"git fetch" was taught to forbid + updates to existing tags without the "--force" option. + + * "git multi-pack-index" learned to detect corruption in the .midx + file it uses, and this feature has been integrated into "git fsck". + + * Generation of (experimental) commit-graph files have so far been + fairly silent, even though it takes noticeable amount of time in a + meaningfully large repository. The users will now see progress + output. + + * The minimum version of Windows supported by Windows port of Git is + now set to Vista. + + * The completion script (in contrib/) learned to complete a handful of + options "git stash list" command takes. + + * The completion script (in contrib/) learned that "git fetch + --multiple" only takes remote names as arguments and no refspecs. + + * "git status" learns to show progress bar when refreshing the index + takes a long time. + (merge ae9af12287 nd/status-refresh-progress later to maint). + + * "git help -a" and "git help -av" give different pieces of + information, and generally the "verbose" version is more friendly + to the new users. "git help -a" by default now uses the more + verbose output (with "--no-verbose", you can go back to the + original). Also "git help -av" now lists aliases and external + commands, which it did not used to. + + * Unlike "grep", "git grep" by default recurses to the whole tree. + The command learned "git grep --recursive" option, so that "git + grep --no-recursive" can serve as a synonym to setting the + max-depth to 0. + + * When pushing into a repository that borrows its objects from an + alternate object store, "git receive-pack" that responds to the + push request on the other side lists the tips of refs in the + alternate to reduce the amount of objects transferred. This + sometimes is detrimental when the number of refs in the alternate + is absurdly large, in which case the bandwidth saved in potentially + fewer objects transferred is wasted in excessively large ref + advertisement. The alternate refs that are advertised are now + configurable with a pair of configuration variables. + + * "git cmd --help" when "cmd" is aliased used to only say "cmd is + aliased to ...". Now it shows that to the standard error stream + and runs "git $cmd --help" where $cmd is the first word of the + alias expansion. + + * The documentation of "git gc" has been updated to mention that it + is no longer limited to "pruning away crufts" but also updates + ancillary files like commit-graph as a part of repository + optimization. + + * "git p4 unshelve" improvements. + + * The logic to select the default user name and e-mail on Windows has + been improved. + (merge 501afcb8b0 js/mingw-default-ident later to maint). + + * The "rev-list --filter" feature learned to exclude all trees via + "tree:0" filter. + + * "git send-email" learned to grab address-looking string on any + trailer whose name ends with "-by"; --suppress-cc=misc-by on the + command line, or setting sendemail.suppresscc configuration + variable to "misc-by", can be used to disable this behaviour. + + * Developer builds now uses -Wunused-function compilation option. + + * One of our CI tests to run with "unusual/experimental/random" + settings now also uses commit-graph and midx. + + * "git mergetool" learned to take the "--[no-]gui" option, just like + "git difftool" does. + + * "git rebase -i" learned a new insn, 'break', that the user can + insert in the to-do list. Upon hitting it, the command returns + control back to the user. + + * New "--pretty=format:" placeholders %GF and %GP that show the GPG + key fingerprints have been invented. + + * On platforms with recent cURL library, http.sslBackend configuration + variable can be used to choose a different SSL backend at runtime. + The Windows port uses this mechanism to switch between OpenSSL and + Secure Channel while talking over the HTTPS protocol. + + * "git send-email" learned to disable SMTP authentication via the + "--smtp-auth=none" option, even when the smtp username is given + (which turns the authentication on by default). + + +Performance, Internal Implementation, Development Support etc. + + * When there are too many packfiles in a repository (which is not + recommended), looking up an object in these would require + consulting many pack .idx files; a new mechanism to have a single + file that consolidates all of these .idx files is introduced. + + * "git submodule update" is getting rewritten piece-by-piece into C. + + * The code for computing history reachability has been shuffled, + obtained a bunch of new tests to cover them, and then being + improved. + + * The unpack_trees() API used in checking out a branch and merging + walks one or more trees along with the index. When the cache-tree + in the index tells us that we are walking a tree whose flattened + contents is known (i.e. matches a span in the index), as linearly + scanning a span in the index is much more efficient than having to + open tree objects recursively and listing their entries, the walk + can be optimized, which has been done. + + * When creating a thin pack, which allows objects to be made into a + delta against another object that is not in the resulting pack but + is known to be present on the receiving end, the code learned to + take advantage of the reachability bitmap; this allows the server + to send a delta against a base beyond the "boundary" commit. + + * spatch transformation to replace boolean uses of !hashcmp() to + newly introduced oideq() is added, and applied, to regain + performance lost due to support of multiple hash algorithms. + + * Fix a bug in which the same path could be registered under multiple + worktree entries if the path was missing (for instance, was removed + manually). Also, as a convenience, expand the number of cases in + which --force is applicable. + + * Split Documentation/config.txt for easier maintenance. + (merge 6014363f0b nd/config-split later to maint). + + * Test helper binaries clean-up. + (merge c9a1f4161f nd/test-tool later to maint). + + * Various tests have been updated to make it easier to swap the + hash function used for object identification. + (merge ae0c89d41b bc/hash-independent-tests later to maint). + + * Update fsck.skipList implementation and documentation. + (merge 371a655074 ab/fsck-skiplist later to maint). + + * An alias that expands to another alias has so far been forbidden, + but now it is allowed to create such an alias. + + * Various test scripts have been updated for style and also correct + handling of exit status of various commands. + + * "gc --auto" ended up calling exit(-1) upon error, which has been + corrected to use exit(1). Also the error reporting behaviour when + daemonized has been updated to exit with zero status when stopping + due to a previously discovered error (which implies there is no + point running gc to improve the situation); we used to exit with + failure in such a case. + + * Various codepaths in the core-ish part learned to work on an + arbitrary in-core index structure, not necessarily the default + instance "the_index". + (merge b3c7eef9b0 nd/the-index later to maint). + + * Code clean-up in the internal machinery used by "git status" and + "git commit --dry-run". + (merge 73ba5d78b4 ss/wt-status-committable later to maint). + + * Some environment variables that control the runtime options of Git + used during tests are getting renamed for consistency. + (merge 4231d1ba99 bp/rename-test-env-var later to maint). + + * A new extension to the index file has been introduced, which allows + the index file to be read in parallel for performance. + + * The oidset API was built on top of the oidmap API which in turn is + on the hashmap API. Replace the implementation to build on top of + the khash API and gain performance. + + * Over some transports, fetching objects with an exact commit object + name can be done without first seeing the ref advertisements. The + code has been optimized to exploit this. + + * In a partial clone that will lazily be hydrated from the + originating repository, we generally want to avoid "does this + object exist (locally)?" on objects that we deliberately omitted + when we created the clone. The cache-tree codepath (which is used + to write a tree object out of the index) however insisted that the + object exists, even for paths that are outside of the partial + checkout area. The code has been updated to avoid such a check. + + * To help developers, an EditorConfig file that attempts to follow + the project convention has been added. + (merge b548d698a0 bc/editorconfig later to maint). + + * The result of coverage test can be combined with "git blame" to + check the test coverage of code introduced recently with a new + 'coverage-diff' tool (in contrib/). + (merge 783faedd65 ds/coverage-diff later to maint). + + * An experiment to fuzz test a few areas, hopefully we can gain more + coverage to various areas. + + * More codepaths are moving away from hardcoded hash sizes. + + * The way the Windows port figures out the current directory has been + improved. + + * The way DLLs are loaded on the Windows port has been improved. + + * Some tests have been reorganized and renamed; "ls t/" now gives a + better overview of what is tested for these scripts than before. + + * "git rebase" and "git rebase -i" have been reimplemented in C. + + * Windows port learned to use nano-second resolution file timestamps. + + +Fixes since v2.19 +----------------- + + * "git interpret-trailers" and its underlying machinery had a buggy + code that attempted to ignore patch text after commit log message, + which triggered in various codepaths that will always get the log + message alone and never get such an input. + (merge 66e83d9b41 jk/trailer-fixes later to maint). + + * Malformed or crafted data in packstream can make our code attempt + to read or write past the allocated buffer and abort, instead of + reporting an error, which has been fixed. + + * "git rebase -i" did not clear the state files correctly when a run + of "squash/fixup" is aborted and then the user manually amended the + commit instead, which has been corrected. + (merge 10d2f35436 js/rebase-i-autosquash-fix later to maint). + + * When fsmonitor is in use, after operation on submodules updates + .gitmodules, we lost track of the fact that we did so and relied on + stale fsmonitor data. + (merge 43f1180814 bp/mv-submodules-with-fsmonitor later to maint). + + * Fix for a long-standing bug that leaves the index file corrupt when + it shrinks during a partial commit. + (merge 6c003d6ffb jk/reopen-tempfile-truncate later to maint). + + * Further fix for O_APPEND emulation on Windows + (merge eeaf7ddac7 js/mingw-o-append later to maint). + + * A corner case bugfix in "git rerere" code. + (merge ad2bf0d9b4 en/rerere-multi-stage-1-fix later to maint). + + * "git add ':(attr:foo)'" is not supported and is supposed to be + rejected while the command line arguments are parsed, but we fail + to reject such a command line upfront. + (merge 84d938b732 nd/attr-pathspec-fix later to maint). + + * Recent update broke the reachability algorithm when refs (e.g. + tags) that point at objects that are not commit were involved, + which has been fixed. + + * "git rebase" etc. in Git 2.19 fails to abort when given an empty + commit log message as result of editing, which has been corrected. + (merge a3ec9eaf38 en/sequencer-empty-edit-result-aborts later to maint). + + * The code to backfill objects in lazily cloned repository did not + work correctly, which has been corrected. + (merge e68302011c jt/lazy-object-fetch-fix later to maint). + + * Update error messages given by "git remote" and make them consistent. + (merge 5025425dff ms/remote-error-message-update later to maint). + + * "git update-ref" learned to make both "--no-deref" and "--stdin" + work at the same time. + (merge d345e9fbe7 en/update-ref-no-deref-stdin later to maint). + + * Recently added "range-diff" had a corner-case bug to cause it + segfault, which has been corrected. + (merge e467a90c7a tg/range-diff-corner-case-fix later to maint). + + * The recently introduced commit-graph auxiliary data is incompatible + with mechanisms such as replace & grafts that "breaks" immutable + nature of the object reference relationship.

The - default mode is 'dotGitOnly'. - -core.ignoreCase:: - Internal variable which enables various workarounds to enable - Git to work better on filesystems that are not case sensitive, - like APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing - finds "makefile" when Git expects "Makefile", Git will assume - it is really the same file, and continue to remember it as - "Makefile". -+ -The default is false, except linkgit:git-clone[1] or linkgit:git-init[1] -will probe and set core.ignoreCase true if appropriate when the repository -is created. -+ -Git relies on the proper configuration of this variable for your operating -and file system. Modifying this value may result in unexpected behavior. - -core.precomposeUnicode:: - This option is only used by Mac OS implementation of Git. - When core.precomposeUnicode=true, Git reverts the unicode decomposition - of filenames done by Mac OS. This is useful when sharing a repository - between Mac OS and Linux or Windows. - (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7). - When false, file names are handled fully transparent by Git, - which is backward compatible with older versions of Git. - -core.protectHFS:: - If set to true, do not allow checkout of paths that would - be considered equivalent to `.git` on an HFS+ filesystem. - Defaults to `true` on Mac OS, and `false` elsewhere. - -core.protectNTFS:: - If set to true, do not allow checkout of paths that would - cause problems with the NTFS filesystem, e.g. conflict with - 8.3 "short" names. - Defaults to `true` on Windows, and `false` elsewhere. - -core.fsmonitor:: - If set, the value of this variable is used as a command which - will identify all files that may have changed since the - requested date/time. This information is used to speed up git by - avoiding unnecessary processing of files that have not changed. - See the "fsmonitor-watchman" section of linkgit:githooks[5]. - -core.trustctime:: - If false, the ctime differences between the index and the - working tree are ignored; useful when the inode change time - is regularly modified by something outside Git (file system - crawlers and some backup systems). - See linkgit:git-update-index[1]. True by default. - -core.splitIndex:: - If true, the split-index feature of the index will be used. - See linkgit:git-update-index[1]. False by default. - -core.untrackedCache:: - Determines what to do about the untracked cache feature of the - index. It will be kept, if this variable is unset or set to - `keep`. It will automatically be added if set to `true`. And - it will automatically be removed, if set to `false`. Before - setting it to `true`, you should check that mtime is working - properly on your system. - See linkgit:git-update-index[1]. `keep` by default. - -core.checkStat:: - When missing or is set to `default`, many fields in the stat - structure are checked to detect if a file has been modified - since Git looked at it. When this configuration variable is - set to `minimal`, sub-second part of mtime and ctime, the - uid and gid of the owner of the file, the inode number (and - the device number, if Git was compiled to use it), are - excluded from the check among these fields, leaving only the - whole-second part of mtime (and ctime, if `core.trustCtime` - is set) and the filesize to be checked. -+ -There are implementations of Git that do not leave usable values in -some fields (e.g. JGit); by excluding these fields from the -comparison, the `minimal` mode may help interoperability when the -same repository is used by these other systems at the same time. - -core.quotePath:: - Commands that output paths (e.g. 'ls-files', 'diff'), will - quote "unusual" characters in the pathname by enclosing the - pathname in double-quotes and escaping those characters with - backslashes in the same way C escapes control characters (e.g. - `\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with - values larger than 0x80 (e.g. octal `\302\265` for "micro" in - UTF-8). If this variable is set to false, bytes higher than - 0x80 are not considered "unusual" any more. Double-quotes, - backslash and control characters are always escaped regardless - of the setting of this variable. A simple space character is - not considered "unusual". Many commands can output pathnames - completely verbatim using the `-z` option. The default value - is true. - -core.eol:: - Sets the line ending type to use in the working directory for - files that have the `text` property set when core.autocrlf is false. - Alternatives are 'lf', 'crlf' and 'native', which uses the platform's - native line ending. The default value is `native`. See - linkgit:gitattributes[5] for more information on end-of-line - conversion. - -core.safecrlf:: - If true, makes Git check if converting `CRLF` is reversible when - end-of-line conversion is active. Git will verify if a command - modifies a file in the work tree either directly or indirectly. - For example, committing a file followed by checking out the - same file should yield the original file in the work tree. If - this is not the case for the current setting of - `core.autocrlf`, Git will reject the file. The variable can - be set to "warn", in which case Git will only warn about an - irreversible conversion but continue the operation. -+ -CRLF conversion bears a slight chance of corrupting data. -When it is enabled, Git will convert CRLF to LF during commit and LF to -CRLF during checkout. A file that contains a mixture of LF and -CRLF before the commit cannot be recreated by Git. For text -files this is the right thing to do: it corrects line endings -such that we have only LF line endings in the repository. -But for binary files that are accidentally classified as text the -conversion can corrupt data. -+ -If you recognize such corruption early you can easily fix it by -setting the conversion type explicitly in .gitattributes. Right -after committing you still have the original file in your work -tree and this file is not yet corrupted. You can explicitly tell -Git that this file is binary and Git will handle the file -appropriately. -+ -Unfortunately, the desired effect of cleaning up text files with -mixed line endings and the undesired effect of corrupting binary -files cannot be distinguished. In both cases CRLFs are removed -in an irreversible way. For text files this is the right thing -to do because CRLFs are line endings, while for binary files -converting CRLFs corrupts data. -+ -Note, this safety check does not mean that a checkout will generate a -file identical to the original file for a different setting of -`core.eol` and `core.autocrlf`, but only for the current one. For -example, a text file with `LF` would be accepted with `core.eol=lf` -and could later be checked out with `core.eol=crlf`, in which case the -resulting file would contain `CRLF`, although the original file -contained `LF`. However, in both work trees the line endings would be -consistent, that is either all `LF` or all `CRLF`, but never mixed. A -file with mixed line endings would be reported by the `core.safecrlf` -mechanism. - -core.autocrlf:: - Setting this variable to "true" is the same as setting - the `text` attribute to "auto" on all files and core.eol to "crlf". - Set to true if you want to have `CRLF` line endings in your - working directory and the repository has LF line endings. - This variable can be set to 'input', - in which case no output conversion is performed. - -core.checkRoundtripEncoding:: - A comma and/or whitespace separated list of encodings that Git - performs UTF-8 round trip checks on if they are used in an - `working-tree-encoding` attribute (see linkgit:gitattributes[5]). - The default value is `SHIFT-JIS`. - -core.symlinks:: - If false, symbolic links are checked out as small plain files that - contain the link text. linkgit:git-update-index[1] and - linkgit:git-add[1] will not change the recorded type to regular - file. Useful on filesystems like FAT that do not support - symbolic links. -+ -The default is true, except linkgit:git-clone[1] or linkgit:git-init[1] -will probe and set core.symlinks false if appropriate when the repository -is created. - -core.gitProxy:: - A "proxy command" to execute (as 'command host port') instead - of establishing direct connection to the remote server when - using the Git protocol for fetching. If the variable value is - in the "COMMAND for DOMAIN" format, the command is applied only - on hostnames ending with the specified domain string. This variable - may be set multiple times and is matched in the given order; - the first match wins. -+ -Can be overridden by the `GIT_PROXY_COMMAND` environment variable -(which always applies universally, without the special "for" -handling). -+ -The special string `none` can be used as the proxy command to -specify that no proxy be used for a given domain pattern. -This is useful for excluding servers inside a firewall from -proxy use, while defaulting to a common proxy for external domains. - -core.sshCommand:: - If this variable is set, `git fetch` and `git push` will - use the specified command instead of `ssh` when they need to - connect to a remote system. The command is in the same form as - the `GIT_SSH_COMMAND` environment variable and is overridden - when the environment variable is set. - -core.ignoreStat:: - If true, Git will avoid using lstat() calls to detect if files have - changed by setting the "assume-unchanged" bit for those tracked files - which it has updated identically in both the index and working tree. -+ -When files are modified outside of Git, the user will need to stage -the modified files explicitly (e.g. see 'Examples' section in -linkgit:git-update-index[1]). -Git will not normally detect changes to those files. -+ -This is useful on systems where lstat() calls are very slow, such as -CIFS/Microsoft Windows. -+ -False by default. - -core.preferSymlinkRefs:: - Instead of the default "symref" format for HEAD - and other symbolic reference files, use symbolic links. - This is sometimes needed to work with old scripts that - expect HEAD to be a symbolic link. - -core.bare:: - If true this repository is assumed to be 'bare' and has no - working directory associated with it. If this is the case a - number of commands that require a working directory will be - disabled, such as linkgit:git-add[1] or linkgit:git-merge[1]. -+ -This setting is automatically guessed by linkgit:git-clone[1] or -linkgit:git-init[1] when the repository was created. By default a -repository that ends in "/.git" is assumed to be not bare (bare = -false), while all other repositories are assumed to be bare (bare -= true). - -core.worktree:: - Set the path to the root of the working tree. - If `GIT_COMMON_DIR` environment variable is set, core.worktree - is ignored and not used for determining the root of working tree. - This can be overridden by the `GIT_WORK_TREE` environment - variable and the `--work-tree` command-line option. - The value can be an absolute path or relative to the path to - the .git directory, which is either specified by --git-dir - or GIT_DIR, or automatically discovered. - If --git-dir or GIT_DIR is specified but none of - --work-tree, GIT_WORK_TREE and core.worktree is specified, - the current working directory is regarded as the top level - of your working tree. -+ -Note that this variable is honored even when set in a configuration -file in a ".git" subdirectory of a directory and its value differs -from the latter directory (e.g. "/path/to/.git/config" has -core.worktree set to "/different/path"), which is most likely a -misconfiguration. Running Git commands in the "/path/to" directory will -still use "/different/path" as the root of the work tree and can cause -confusion unless you know what you are doing (e.g. you are creating a -read-only snapshot of the same index to a location different from the -repository's usual working tree). - -core.logAllRefUpdates:: - Enable the reflog. Updates to a ref <ref> is logged to the file - "`$GIT_DIR/logs/<ref>`", by appending the new and old - SHA-1, the date/time and the reason of the update, but - only when the file exists. If this configuration - variable is set to `true`, missing "`$GIT_DIR/logs/<ref>`" - file is automatically created for branch heads (i.e. under - `refs/heads/`), remote refs (i.e. under `refs/remotes/`), - note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`. - If it is set to `always`, then a missing reflog is automatically - created for any ref under `refs/`. -+ -This information can be used to determine what commit -was the tip of a branch "2 days ago". -+ -This value is true by default in a repository that has -a working directory associated with it, and false by -default in a bare repository. - -core.repositoryFormatVersion:: - Internal variable identifying the repository format and layout - version. - -core.sharedRepository:: - When 'group' (or 'true'), the repository is made shareable between - several users in a group (making sure all the files and objects are - group-writable). When 'all' (or 'world' or 'everybody'), the - repository will be readable by all users, additionally to being - group-shareable. When 'umask' (or 'false'), Git will use permissions - reported by umask(2). When '0xxx', where '0xxx' is an octal number, - files in the repository will have this mode value. '0xxx' will override - user's umask value (whereas the other options will only override - requested parts of the user's umask value). Examples: '0660' will make - the repo read/write-able for the owner and group, but inaccessible to - others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a - repository that is group-readable but not group-writable. - See linkgit:git-init[1]. False by default. - -core.warnAmbiguousRefs:: - If true, Git will warn you if the ref name you passed it is ambiguous - and might match multiple refs in the repository. True by default. - -core.compression:: - An integer -1..9, indicating a default compression level. - -1 is the zlib default. 0 means no compression, - and 1..9 are various speed/size tradeoffs, 9 being slowest. - If set, this provides a default to other compression variables, - such as `core.looseCompression` and `pack.compression`. - -core.looseCompression:: - An integer -1..9, indicating the compression level for objects that - are not in a pack file. -1 is the zlib default. 0 means no - compression, and 1..9 are various speed/size tradeoffs, 9 being - slowest. If not set, defaults to core.compression. If that is - not set, defaults to 1 (best speed). - -core.packedGitWindowSize:: - Number of bytes of a pack file to map into memory in a - single mapping operation. Larger window sizes may allow - your system to process a smaller number of large pack files - more quickly. Smaller window sizes will negatively affect - performance due to increased calls to the operating system's - memory manager, but may improve performance when accessing - a large number of large pack files. -+ -Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 -MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should -be reasonable for all users/operating systems. You probably do -not need to adjust this value. -+ -Common unit suffixes of 'k', 'm', or 'g' are supported. +include::config/core.txt[] -core.packedGitLimit:: - Maximum number of bytes to map simultaneously into memory - from pack files. If Git needs to access more than this many - bytes at once to complete an operation it will unmap existing - regions to reclaim virtual address space within the process. -+ -Default is 256 MiB on 32 bit platforms and 32 TiB (effectively -unlimited) on 64 bit platforms. -This should be reasonable for all users/operating systems, except on -the largest projects. You probably do not need to adjust this value. -+ -Common unit suffixes of 'k', 'm', or 'g' are supported. - -core.deltaBaseCacheLimit:: - Maximum number of bytes to reserve for caching base objects - that may be referenced by multiple deltified objects. By storing the - entire decompressed base objects in a cache Git is able - to avoid unpacking and decompressing frequently used base - objects multiple times. -+ -Default is 96 MiB on all platforms. This should be reasonable -for all users/operating systems, except on the largest projects. -You probably do not need to adjust this value. -+ -Common unit suffixes of 'k', 'm', or 'g' are supported. - -core.bigFileThreshold:: - Files larger than this size are stored deflated, without - attempting delta compression. Storing large files without - delta compression avoids excessive memory usage, at the - slight expense of increased disk usage. Additionally files - larger than this size are always treated as binary. -+ -Default is 512 MiB on all platforms. This should be reasonable -for most projects as source code and other text files can still -be delta compressed, but larger binary media files won't be. -+ -Common unit suffixes of 'k', 'm', or 'g' are supported. - -core.excludesFile:: - Specifies the pathname to the file that contains patterns to - describe paths that are not meant to be tracked, in addition - to '.gitignore' (per-directory) and '.git/info/exclude'. - Defaults to `$XDG_CONFIG_HOME/git/ignore`. - If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore` - is used instead. See linkgit:gitignore[5]. - -core.askPass:: - Some commands (e.g. svn and http interfaces) that interactively - ask for a password can be told to use an external program given - via the value of this variable. Can be overridden by the `GIT_ASKPASS` - environment variable. If not set, fall back to the value of the - `SSH_ASKPASS` environment variable or, failing that, a simple password - prompt. The external program shall be given a suitable prompt as - command-line argument and write the password on its STDOUT. - -core.attributesFile:: - In addition to '.gitattributes' (per-directory) and - '.git/info/attributes', Git looks into this file for attributes - (see linkgit:gitattributes[5]). Path expansions are made the same - way as for `core.excludesFile`. Its default value is - `$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not - set or empty, `$HOME/.config/git/attributes` is used instead. - -core.hooksPath:: - By default Git will look for your hooks in the - '$GIT_DIR/hooks' directory. Set this to different path, - e.g. '/etc/git/hooks', and Git will try to find your hooks in - that directory, e.g. '/etc/git/hooks/pre-receive' instead of - in '$GIT_DIR/hooks/pre-receive'. -+ -The path can be either absolute or relative. A relative path is -taken as relative to the directory where the hooks are run (see -the "DESCRIPTION" section of linkgit:githooks[5]). -+ -This configuration variable is useful in cases where you'd like to -centrally configure your Git hooks instead of configuring them on a -per-repository basis, or as a more flexible and centralized -alternative to having an `init.templateDir` where you've changed -default hooks. - -core.editor:: - Commands such as `commit` and `tag` that let you edit - messages by launching an editor use the value of this - variable when it is set, and the environment variable - `GIT_EDITOR` is not set. See linkgit:git-var[1]. - -core.commentChar:: - Commands such as `commit` and `tag` that let you edit - messages consider a line that begins with this character - commented, and removes them after the editor returns - (default '#'). -+ -If set to "auto", `git-commit` would select a character that is not -the beginning character of any line in existing commit messages. - -core.filesRefLockTimeout:: - The length of time, in milliseconds, to retry when trying to - lock an individual reference. Value 0 means not to retry at - all; -1 means to try indefinitely. Default is 100 (i.e., - retry for 100ms). - -core.packedRefsTimeout:: - The length of time, in milliseconds, to retry when trying to - lock the `packed-refs` file. Value 0 means not to retry at - all; -1 means to try indefinitely. Default is 1000 (i.e., - retry for 1 second). - -sequence.editor:: - Text editor used by `git rebase -i` for editing the rebase instruction file. - The value is meant to be interpreted by the shell when it is used. - It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable. - When not configured the default commit message editor is used instead. - -core.pager:: - Text viewer for use by Git commands (e.g., 'less'). The value - is meant to be interpreted by the shell. The order of preference - is the `$GIT_PAGER` environment variable, then `core.pager` - configuration, then `$PAGER`, and then the default chosen at - compile time (usually 'less'). -+ -When the `LESS` environment variable is unset, Git sets it to `FRX` -(if `LESS` environment variable is set, Git does not change it at -all). If you want to selectively override Git's default setting -for `LESS`, you can set `core.pager` to e.g. `less -S`. This will -be passed to the shell by Git, which will translate the final -command to `LESS=FRX less -S`. The environment does not set the -`S` option but the command line does, instructing less to truncate -long lines. Similarly, setting `core.pager` to `less -+F` will -deactivate the `F` option specified by the environment from the -command-line, deactivating the "quit if one screen" behavior of -`less`. One can specifically activate some flags for particular -commands: for example, setting `pager.blame` to `less -S` enables -line truncation only for `git blame`. -+ -Likewise, when the `LV` environment variable is unset, Git sets it -to `-c`. You can override this setting by exporting `LV` with -another value or setting `core.pager` to `lv +c`. - -core.whitespace:: - A comma separated list of common whitespace problems to - notice. 'git diff' will use `color.diff.whitespace` to - highlight them, and 'git apply --whitespace=error' will - consider them as errors. You can prefix `-` to disable - any of them (e.g. `-trailing-space`): -+ -* `blank-at-eol` treats trailing whitespaces at the end of the line - as an error (enabled by default). -* `space-before-tab` treats a space character that appears immediately - before a tab character in the initial indent part of the line as an - error (enabled by default). -* `indent-with-non-tab` treats a line that is indented with space - characters instead of the equivalent tabs as an error (not enabled by - default). -* `tab-in-indent` treats a tab character in the initial indent part of - the line as an error (not enabled by default). -* `blank-at-eof` treats blank lines added at the end of file as an error - (enabled by default). -* `trailing-space` is a short-hand to cover both `blank-at-eol` and - `blank-at-eof`. -* `cr-at-eol` treats a carriage-return at the end of line as - part of the line terminator, i.e. with it, `trailing-space` - does not trigger if the character before such a carriage-return - is not a whitespace (not enabled by default). -* `tabwidth=<n>` tells how many character positions a tab occupies; this - is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent` - errors. The default tab width is 8. Allowed values are 1 to 63. - -core.fsyncObjectFiles:: - This boolean will enable 'fsync()' when writing object files. -+ -This is a total waste of time and effort on a filesystem that orders -data writes properly, but can be useful for filesystems that do not use -journalling (traditional UNIX filesystems) or that only journal metadata -and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback"). +extensions.worktreeConfig:: + If set, by default "git config" reads from both "config" and + "config.worktree" file from GIT_DIR in that order. In + multiple working directory mode, "config" file is shared while + "config.worktree" is per-working directory (i.e., it's in + GIT_COMMON_DIR/worktrees/<id>/config.worktree) -core.preloadIndex:: - Enable parallel index preload for operations like 'git diff' -+ -This can speed up operations like 'git diff' and 'git status' especially -on filesystems like NFS that have weak caching semantics and thus -relatively high IO latencies. When enabled, Git will do the -index comparison to the filesystem data in parallel, allowing -overlapping IO's. Defaults to true. - -core.createObject:: - You can set this to 'link', in which case a hardlink followed by - a delete of the source are used to make sure that object creation - will not overwrite existing objects. -+ -On some file system/operating system combinations, this is unreliable. -Set this config setting to 'rename' there; However, This will remove the -check that makes sure that existing object files will not get overwritten. - -core.notesRef:: - When showing commit messages, also show notes which are stored in - the given ref. The ref must be fully qualified. If the given - ref does not exist, it is not an error but means that no - notes should be printed. -+ -This setting defaults to "refs/notes/commits", and it can be overridden by -the `GIT_NOTES_REF` environment variable. See linkgit:git-notes[1]. - -core.commitGraph:: - If true, then git will read the commit-graph file (if it exists) - to parse the graph structure of commits. Defaults to false. See - linkgit:git-commit-graph[1] for more information. - -core.useReplaceRefs:: - If set to `false`, behave as if the `--no-replace-objects` - option was given on the command line. See linkgit:git[1] and - linkgit:git-replace[1] for more information. - -core.multiPackIndex:: - Use the multi-pack-index file to track multiple packfiles using a - single index. See link:technical/multi-pack-index.html[the - multi-pack-index design document]. - -core.sparseCheckout:: - Enable "sparse checkout" feature. See section "Sparse checkout" in - linkgit:git-read-tree[1] for more information. - -core.abbrev:: - Set the length object names are abbreviated to. If - unspecified or set to "auto", an appropriate value is - computed based on the approximate number of packed objects - in your repository, which hopefully is enough for - abbreviated object names to stay unique for some time. - The minimum length is 4. - -add.ignoreErrors:: -add.ignore-errors (deprecated):: - Tells 'git add' to continue adding files when some files cannot be - added due to indexing errors. Equivalent to the `--ignore-errors` - option of linkgit:git-add[1]. `add.ignore-errors` is deprecated, - as it does not follow the usual naming convention for configuration - variables. - -alias.*:: - Command aliases for the linkgit:git[1] command wrapper - e.g. - after defining "alias.last = cat-file commit HEAD", the invocation - "git last" is equivalent to "git cat-file commit HEAD". To avoid - confusion and troubles with script usage, aliases that - hide existing Git commands are ignored. Arguments are split by - spaces, the usual shell quoting and escaping is supported. - A quote pair or a backslash can be used to quote them. -+ -If the alias expansion is prefixed with an exclamation point, -it will be treated as a shell command. For example, defining -"alias.new = !gitk --all --not ORIG_HEAD", the invocation -"git new" is equivalent to running the shell command -"gitk --all --not ORIG_HEAD". Note that shell commands will be -executed from the top-level directory of a repository, which may -not necessarily be the current directory. -`GIT_PREFIX` is set as returned by running 'git rev-parse --show-prefix' -from the original current directory. See linkgit:git-rev-parse[1]. - -am.keepcr:: - If true, git-am will call git-mailsplit for patches in mbox format - with parameter `--keep-cr`. In this case git-mailsplit will - not remove `\r` from lines ending with `\r\n`. Can be overridden - by giving `--no-keep-cr` from the command line. - See linkgit:git-am[1], linkgit:git-mailsplit[1]. - -am.threeWay:: - By default, `git am` will fail if the patch does not apply cleanly. When - set to true, this setting tells `git am` to fall back on 3-way merge if - the patch records the identity of blobs it is supposed to apply to and - we have those blobs available locally (equivalent to giving the `--3way` - option from the command line). Defaults to `false`. - See linkgit:git-am[1]. - -apply.ignoreWhitespace:: - When set to 'change', tells 'git apply' to ignore changes in - whitespace, in the same way as the `--ignore-space-change` - option. - When set to one of: no, none, never, false tells 'git apply' to - respect all whitespace differences. - See linkgit:git-apply[1]. - -apply.whitespace:: - Tells 'git apply' how to handle whitespaces, in the same way - as the `--whitespace` option. See linkgit:git-apply[1]. - -blame.blankBoundary:: - Show blank commit object name for boundary commits in - linkgit:git-blame[1]. This option defaults to false. - -blame.coloring:: - This determines the coloring scheme to be applied to blame - output. It can be 'repeatedLines', 'highlightRecent', - or 'none' which is the default. - -blame.date:: - Specifies the format used to output dates in linkgit:git-blame[1]. - If unset the iso format is used. For supported values, - see the discussion of the `--date` option at linkgit:git-log[1]. - -blame.showEmail:: - Show the author email instead of author name in linkgit:git-blame[1]. - This option defaults to false. - -blame.showRoot:: - Do not treat root commits as boundaries in linkgit:git-blame[1]. - This option defaults to false. - -branch.autoSetupMerge:: - Tells 'git branch' and 'git checkout' to set up new branches - so that linkgit:git-pull[1] will appropriately merge from the - starting point branch. Note that even if this option is not set, - this behavior can be chosen per-branch using the `--track` - and `--no-track` options. The valid settings are: `false` -- no - automatic setup is done; `true` -- automatic setup is done when the - starting point is a remote-tracking branch; `always` -- - automatic setup is done when the starting point is either a - local branch or remote-tracking - branch. This option defaults to true. - -branch.autoSetupRebase:: - When a new branch is created with 'git branch' or 'git checkout' - that tracks another branch, this variable tells Git to set - up pull to rebase instead of merge (see "branch.<name>.rebase"). - When `never`, rebase is never automatically set to true. - When `local`, rebase is set to true for tracked branches of - other local branches. - When `remote`, rebase is set to true for tracked branches of - remote-tracking branches. - When `always`, rebase will be set to true for all tracking - branches. - See "branch.autoSetupMerge" for details on how to set up a - branch to track another branch. - This option defaults to never. - -branch.sort:: - This variable controls the sort ordering of branches when displayed by - linkgit:git-branch[1]. Without the "--sort=<value>" option provided, the - value of this variable will be used as the default. - See linkgit:git-for-each-ref[1] field names for valid values. - -branch.<name>.remote:: - When on branch <name>, it tells 'git fetch' and 'git push' - which remote to fetch from/push to. The remote to push to - may be overridden with `remote.pushDefault` (for all branches). - The remote to push to, for the current branch, may be further - overridden by `branch.<name>.pushRemote`. If no remote is - configured, or if you are not on any branch, it defaults to - `origin` for fetching and `remote.pushDefault` for pushing. - Additionally, `.` (a period) is the current local repository - (a dot-repository), see `branch.<name>.merge`'s final note below. - -branch.<name>.pushRemote:: - When on branch <name>, it overrides `branch.<name>.remote` for - pushing. It also overrides `remote.pushDefault` for pushing - from branch <name>. When you pull from one place (e.g. your - upstream) and push to another place (e.g. your own publishing - repository), you would want to set `remote.pushDefault` to - specify the remote to push to for all branches, and use this - option to override it for a specific branch. - -branch.<name>.merge:: - Defines, together with branch.<name>.remote, the upstream branch - for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which - branch to merge and can also affect 'git push' (see push.default). - When in branch <name>, it tells 'git fetch' the default - refspec to be marked for merging in FETCH_HEAD. The value is - handled like the remote part of a refspec, and must match a - ref which is fetched from the remote given by - "branch.<name>.remote". - The merge information is used by 'git pull' (which at first calls - 'git fetch') to lookup the default branch for merging. Without - this option, 'git pull' defaults to merge the first refspec fetched. - Specify multiple values to get an octopus merge. - If you wish to setup 'git pull' so that it merges into <name> from - another branch in the local repository, you can point - branch.<name>.merge to the desired branch, and use the relative path - setting `.` (a period) for branch.<name>.remote. - -branch.<name>.mergeOptions:: - Sets default options for merging into branch <name>. The syntax and - supported options are the same as those of linkgit:git-merge[1], but - option values containing whitespace characters are currently not - supported. - -branch.<name>.rebase:: - When true, rebase the branch <name> on top of the fetched branch, - instead of merging the default branch from the default remote when - "git pull" is run. See "pull.rebase" for doing this in a non - branch-specific manner. -+ -When `merges`, pass the `--rebase-merges` option to 'git rebase' -so that the local merge commits are included in the rebase (see -linkgit:git-rebase[1] for details). -+ -When preserve, also pass `--preserve-merges` along to 'git rebase' -so that locally committed merge commits will not be flattened -by running 'git pull'. -+ -When the value is `interactive`, the rebase is run in interactive mode. -+ -*NOTE*: this is a possibly dangerous operation; do *not* use -it unless you understand the implications (see linkgit:git-rebase[1] -for details). - -branch.<name>.description:: - Branch description, can be edited with - `git branch --edit-description`. Branch description is - automatically added in the format-patch cover letter or - request-pull summary. - -browser.<tool>.cmd:: - Specify the command to invoke the specified browser. The - specified command is evaluated in shell with the URLs passed - as arguments. (See linkgit:git-web{litdd}browse[1].) - -browser.<tool>.path:: - Override the path for the given tool that may be used to - browse HTML help (see `-w` option in linkgit:git-help[1]) or a - working repository in gitweb (see linkgit:git-instaweb[1]). - -checkout.defaultRemote:: - When you run 'git checkout <something>' and only have one - remote, it may implicitly fall back on checking out and - tracking e.g. 'origin/<something>'. This stops working as soon - as you have more than one remote with a '<something>' - reference. This setting allows for setting the name of a - preferred remote that should always win when it comes to - disambiguation. The typical use-case is to set this to - `origin`. -+ -Currently this is used by linkgit:git-checkout[1] when 'git checkout -<something>' will checkout the '<something>' branch on another remote, -and by linkgit:git-worktree[1] when 'git worktree add' refers to a -remote branch. This setting might be used for other checkout-like -commands or functionality in the future. - -checkout.optimizeNewBranch:: - Optimizes the performance of "git checkout -b <new_branch>" when - using sparse-checkout. When set to true, git will not update the - repo based on the current sparse-checkout settings. This means it - will not update the skip-worktree bit in the index nor add/remove - files in the working directory to reflect the current sparse checkout - settings nor will it show the local changes. - -clean.requireForce:: - A boolean to make git-clean do nothing unless given -f, - -i or -n. Defaults to true. - -color.advice:: - A boolean to enable/disable color in hints (e.g. when a push - failed, see `advice.*` for a list). May be set to `always`, - `false` (or `never`) or `auto` (or `true`), in which case colors - are used only when the error output goes to a terminal. If - unset, then the value of `color.ui` is used (`auto` by default). - -color.advice.hint:: - Use customized color for hints. - -color.blame.highlightRecent:: - This can be used to color the metadata of a blame line depending - on age of the line. -+ -This setting should be set to a comma-separated list of color and date settings, -starting and ending with a color, the dates should be set from oldest to newest. -The metadata will be colored given the colors if the the line was introduced -before the given timestamp, overwriting older timestamped colors. -+ -Instead of an absolute timestamp relative timestamps work as well, e.g. -2.weeks.ago is valid to address anything older than 2 weeks. -+ -It defaults to 'blue,12 month ago,white,1 month ago,red', which colors -everything older than one year blue, recent changes between one month and -one year old are kept white, and lines introduced within the last month are -colored red. - -color.blame.repeatedLines:: - Use the customized color for the part of git-blame output that - is repeated meta information per line (such as commit id, - author name, date and timezone). Defaults to cyan. - -color.branch:: - A boolean to enable/disable color in the output of - linkgit:git-branch[1]. May be set to `always`, - `false` (or `never`) or `auto` (or `true`), in which case colors are used - only when the output is to a terminal. If unset, then the - value of `color.ui` is used (`auto` by default). - -color.branch.<slot>:: - Use customized color for branch coloration. `<slot>` is one of - `current` (the current branch), `local` (a local branch), - `remote` (a remote-tracking branch in refs/remotes/), - `upstream` (upstream tracking branch), `plain` (other - refs). - -color.diff:: - Whether to use ANSI escape sequences to add color to patches. - If this is set to `always`, linkgit:git-diff[1], - linkgit:git-log[1], and linkgit:git-show[1] will use color - for all patches. If it is set to `true` or `auto`, those - commands will only use color when output is to the terminal. - If unset, then the value of `color.ui` is used (`auto` by - default). -+ -This does not affect linkgit:git-format-patch[1] or the -'git-diff-{asterisk}' plumbing commands. Can be overridden on the -command line with the `--color[=<when>]` option. - -color.diff.<slot>:: - Use customized color for diff colorization. `<slot>` specifies - which part of the patch to use the specified color, and is one - of `context` (context text - `plain` is a historical synonym), - `meta` (metainformation), `frag` - (hunk header), 'func' (function in hunk header), `old` (removed lines), - `new` (added lines), `commit` (commit headers), `whitespace` - (highlighting whitespace errors), `oldMoved` (deleted lines), - `newMoved` (added lines), `oldMovedDimmed`, `oldMovedAlternative`, - `oldMovedAlternativeDimmed`, `newMovedDimmed`, `newMovedAlternative` - `newMovedAlternativeDimmed` (See the '<mode>' - setting of '--color-moved' in linkgit:git-diff[1] for details), - `contextDimmed`, `oldDimmed`, `newDimmed`, `contextBold`, - `oldBold`, and `newBold` (see linkgit:git-range-diff[1] for details). - -color.decorate.<slot>:: - Use customized color for 'git log --decorate' output. `<slot>` is one - of `branch`, `remoteBranch`, `tag`, `stash` or `HEAD` for local - branches, remote-tracking branches, tags, stash and HEAD, respectively - and `grafted` for grafted commits. - -color.grep:: - When set to `always`, always highlight matches. When `false` (or - `never`), never. When set to `true` or `auto`, use color only - when the output is written to the terminal. If unset, then the - value of `color.ui` is used (`auto` by default). - -color.grep.<slot>:: - Use customized color for grep colorization. `<slot>` specifies which - part of the line to use the specified color, and is one of -+ --- -`context`;; - non-matching text in context lines (when using `-A`, `-B`, or `-C`) -`filename`;; - filename prefix (when not using `-h`) -`function`;; - function name lines (when using `-p`) -`lineNumber`;; - line number prefix (when using `-n`) -`column`;; - column number prefix (when using `--column`) -`match`;; - matching text (same as setting `matchContext` and `matchSelected`) -`matchContext`;; - matching text in context lines -`matchSelected`;; - matching text in selected lines -`selected`;; - non-matching text in selected lines -`separator`;; - separators between fields on a line (`:`, `-`, and `=`) - and between hunks (`--`) --- - -color.interactive:: - When set to `always`, always use colors for interactive prompts - and displays (such as those used by "git-add --interactive" and - "git-clean --interactive"). When false (or `never`), never. - When set to `true` or `auto`, use colors only when the output is - to the terminal. If unset, then the value of `color.ui` is - used (`auto` by default). - -color.interactive.<slot>:: - Use customized color for 'git add --interactive' and 'git clean - --interactive' output. `<slot>` may be `prompt`, `header`, `help` - or `error`, for four distinct types of normal output from - interactive commands. - -color.pager:: - A boolean to enable/disable colored output when the pager is in - use (default is true). - -color.push:: - A boolean to enable/disable color in push errors. May be set to - `always`, `false` (or `never`) or `auto` (or `true`), in which - case colors are used only when the error output goes to a terminal. - If unset, then the value of `color.ui` is used (`auto` by default). - -color.push.error:: - Use customized color for push errors. - -color.remote:: - If set, keywords at the start of the line are highlighted. The - keywords are "error", "warning", "hint" and "success", and are - matched case-insensitively. May be set to `always`, `false` (or - `never`) or `auto` (or `true`). If unset, then the value of - `color.ui` is used (`auto` by default). - -color.remote.<slot>:: - Use customized color for each remote keyword. `<slot>` may be - `hint`, `warning`, `success` or `error` which match the - corresponding keyword. - -color.showBranch:: - A boolean to enable/disable color in the output of - linkgit:git-show-branch[1]. May be set to `always`, - `false` (or `never`) or `auto` (or `true`), in which case colors are used - only when the output is to a terminal. If unset, then the - value of `color.ui` is used (`auto` by default). - -color.status:: - A boolean to enable/disable color in the output of - linkgit:git-status[1]. May be set to `always`, - `false` (or `never`) or `auto` (or `true`), in which case colors are used - only when the output is to a terminal. If unset, then the - value of `color.ui` is used (`auto` by default). - -color.status.<slot>:: - Use customized color for status colorization. `<slot>` is - one of `header` (the header text of the status message), - `added` or `updated` (files which are added but not committed), - `changed` (files which are changed but not added in the index), - `untracked` (files which are not tracked by Git), - `branch` (the current branch), - `nobranch` (the color the 'no branch' warning is shown in, defaulting - to red), - `localBranch` or `remoteBranch` (the local and remote branch names, - respectively, when branch and tracking information is displayed in the - status short-format), or - `unmerged` (files which have unmerged changes). - -color.transport:: - A boolean to enable/disable color when pushes are rejected. May be - set to `always`, `false` (or `never`) or `auto` (or `true`), in which - case colors are used only when the error output goes to a terminal. - If unset, then the value of `color.ui` is used (`auto` by default). - -color.transport.rejected:: - Use customized color when a push was rejected. - -color.ui:: - This variable determines the default value for variables such - as `color.diff` and `color.grep` that control the use of color - per command family. Its scope will expand as more commands learn - configuration to set a default for the `--color` option. Set it - to `false` or `never` if you prefer Git commands not to use - color unless enabled explicitly with some other configuration - or the `--color` option. Set it to `always` if you want all - output not intended for machine consumption to use color, to - `true` or `auto` (this is the default since Git 1.8.4) if you - want such output to use color when written to the terminal. - -column.ui:: - Specify whether supported commands should output in columns. - This variable consists of a list of tokens separated by spaces - or commas: -+ -These options control when the feature should be enabled -(defaults to 'never'): -+ --- -`always`;; - always show in columns -`never`;; - never show in columns -`auto`;; - show in columns if the output is to the terminal --- -+ -These options control layout (defaults to 'column'). Setting any -of these implies 'always' if none of 'always', 'never', or 'auto' are -specified. -+ --- -`column`;; - fill columns before rows -`row`;; - fill rows before columns -`plain`;; - show in one column --- -+ -Finally, these options can be combined with a layout option (defaults -to 'nodense'): -+ --- -`dense`;; - make unequal size columns to utilize more space -`nodense`;; - make equal size columns --- - -column.branch:: - Specify whether to output branch listing in `git branch` in columns. - See `column.ui` for details. - -column.clean:: - Specify the layout when list items in `git clean -i`, which always - shows files and directories in columns. See `column.ui` for details. - -column.status:: - Specify whether to output untracked files in `git status` in columns. - See `column.ui` for details. - -column.tag:: - Specify whether to output tag listing in `git tag` in columns. - See `column.ui` for details. - -commit.cleanup:: - This setting overrides the default of the `--cleanup` option in - `git commit`. See linkgit:git-commit[1] for details. Changing the - default can be useful when you always want to keep lines that begin - with comment character `#` in your log message, in which case you - would do `git config commit.cleanup whitespace` (note that you will - have to remove the help lines that begin with `#` in the commit log - template yourself, if you do this). - -commit.gpgSign:: - - A boolean to specify whether all commits should be GPG signed. - Use of this option when doing operations such as rebase can - result in a large number of commits being signed. It may be - convenient to use an agent to avoid typing your GPG passphrase - several times. - -commit.status:: - A boolean to enable/disable inclusion of status information in the - commit message template when using an editor to prepare the commit - message. Defaults to true. - -commit.template:: - Specify the pathname of a file to use as the template for - new commit messages. - -commit.verbose:: - A boolean or int to specify the level of verbose with `git commit`. - See linkgit:git-commit[1]. - -credential.helper:: - Specify an external helper to be called when a username or - password credential is needed; the helper may consult external - storage to avoid prompting the user for the credentials. Note - that multiple helpers may be defined. See linkgit:gitcredentials[7] - for details. - -credential.useHttpPath:: - When acquiring credentials, consider the "path" component of an http - or https URL to be important. Defaults to false. See - linkgit:gitcredentials[7] for more information. - -credential.username:: - If no username is set for a network authentication, use this username - by default. See credential.<context>.* below, and - linkgit:gitcredentials[7]. - -credential.<url>.*:: - Any of the credential.* options above can be applied selectively to - some credentials. For example "credential.https://example.com.username" - would set the default username only for https connections to - example.com. See linkgit:gitcredentials[7] for details on how URLs are - matched. - -credentialCache.ignoreSIGHUP:: - Tell git-credential-cache--daemon to ignore SIGHUP, instead of quitting. - -completion.commands:: - This is only used by git-completion.bash to add or remove - commands from the list of completed commands. Normally only - porcelain commands and a few select others are completed. You - can add more commands, separated by space, in this - variable. Prefixing the command with '-' will remove it from - the existing list. - -include::diff-config.txt[] - -difftool.<tool>.path:: - Override the path for the given tool. This is useful in case - your tool is not in the PATH. - -difftool.<tool>.cmd:: - Specify the command to invoke the specified diff tool. - The specified command is evaluated in shell with the following - variables available: 'LOCAL' is set to the name of the temporary - file containing the contents of the diff pre-image and 'REMOTE' - is set to the name of the temporary file containing the contents - of the diff post-image. - -difftool.prompt:: - Prompt before each invocation of the diff tool. - -fastimport.unpackLimit:: - If the number of objects imported by linkgit:git-fast-import[1] - is below this limit, then the objects will be unpacked into - loose object files. However if the number of imported objects - equals or exceeds this limit then the pack will be stored as a - pack. Storing the pack from a fast-import can make the import - operation complete faster, especially on slow filesystems. If - not set, the value of `transfer.unpackLimit` is used instead. - -fetch.recurseSubmodules:: - This option can be either set to a boolean value or to 'on-demand'. - Setting it to a boolean changes the behavior of fetch and pull to - unconditionally recurse into submodules when set to true or to not - recurse at all when set to false. When set to 'on-demand' (the default - value), fetch and pull will only recurse into a populated submodule - when its superproject retrieves a commit that updates the submodule's - reference. - -fetch.fsckObjects:: - If it is set to true, git-fetch-pack will check all fetched - objects. See `transfer.fsckObjects` for what's - checked. Defaults to false. If not set, the value of - `transfer.fsckObjects` is used instead. - -fetch.fsck.<msg-id>:: - Acts like `fsck.<msg-id>`, but is used by - linkgit:git-fetch-pack[1] instead of linkgit:git-fsck[1]. See - the `fsck.<msg-id>` documentation for details. - -fetch.fsck.skipList:: - Acts like `fsck.skipList`, but is used by - linkgit:git-fetch-pack[1] instead of linkgit:git-fsck[1]. See - the `fsck.skipList` documentation for details. - -fetch.unpackLimit:: - If the number of objects fetched over the Git native - transfer is below this - limit, then the objects will be unpacked into loose object - files. However if the number of received objects equals or - exceeds this limit then the received pack will be stored as - a pack, after adding any missing delta bases. Storing the - pack from a push can make the push operation complete faster, - especially on slow filesystems. If not set, the value of - `transfer.unpackLimit` is used instead. - -fetch.prune:: - If true, fetch will automatically behave as if the `--prune` - option was given on the command line. See also `remote.<name>.prune` - and the PRUNING section of linkgit:git-fetch[1]. - -fetch.pruneTags:: - If true, fetch will automatically behave as if the - `refs/tags/*:refs/tags/*` refspec was provided when pruning, - if not set already. This allows for setting both this option - and `fetch.prune` to maintain a 1=1 mapping to upstream - refs. See also `remote.<name>.pruneTags` and the PRUNING - section of linkgit:git-fetch[1]. - -fetch.output:: - Control how ref update status is printed. Valid values are - `full` and `compact`. Default value is `full`. See section - OUTPUT in linkgit:git-fetch[1] for detail. - -fetch.negotiationAlgorithm:: - Control how information about the commits in the local repository is - sent when negotiating the contents of the packfile to be sent by the - server. Set to "skipping" to use an algorithm that skips commits in an - effort to converge faster, but may result in a larger-than-necessary - packfile; The default is "default" which instructs Git to use the default algorithm - that never skips commits (unless the server has acknowledged it or one - of its descendants). - Unknown values will cause 'git fetch' to error out. -+ -See also the `--negotiation-tip` option for linkgit:git-fetch[1]. - -format.attach:: - Enable multipart/mixed attachments as the default for - 'format-patch'. The value can also be a double quoted string - which will enable attachments as the default and set the - value as the boundary. See the --attach option in - linkgit:git-format-patch[1]. - -format.from:: - Provides the default value for the `--from` option to format-patch. - Accepts a boolean value, or a name and email address. If false, - format-patch defaults to `--no-from`, using commit authors directly in - the "From:" field of patch mails. If true, format-patch defaults to - `--from`, using your committer identity in the "From:" field of patch - mails and including a "From:" field in the body of the patch mail if - different. If set to a non-boolean value, format-patch uses that - value instead of your committer identity. Defaults to false. - -format.numbered:: - A boolean which can enable or disable sequence numbers in patch - subjects. It defaults to "auto" which enables it only if there - is more than one patch. It can be enabled or disabled for all - messages by setting it to "true" or "false". See --numbered - option in linkgit:git-format-patch[1]. - -format.headers:: - Additional email headers to include in a patch to be submitted - by mail. See linkgit:git-format-patch[1]. - -format.to:: -format.cc:: - Additional recipients to include in a patch to be submitted - by mail. See the --to and --cc options in - linkgit:git-format-patch[1]. - -format.subjectPrefix:: - The default for format-patch is to output files with the '[PATCH]' - subject prefix. Use this variable to change that prefix. - -format.signature:: - The default for format-patch is to output a signature containing - the Git version number. Use this variable to change that default. - Set this variable to the empty string ("") to suppress - signature generation. - -format.signatureFile:: - Works just like format.signature except the contents of the - file specified by this variable will be used as the signature. - -format.suffix:: - The default for format-patch is to output files with the suffix - `.patch`. Use this variable to change that suffix (make sure to - include the dot if you want it). - -format.pretty:: - The default pretty format for log/show/whatchanged command, - See linkgit:git-log[1], linkgit:git-show[1], - linkgit:git-whatchanged[1]. - -format.thread:: - The default threading style for 'git format-patch'. Can be - a boolean value, or `shallow` or `deep`. `shallow` threading - makes every mail a reply to the head of the series, - where the head is chosen from the cover letter, the - `--in-reply-to`, and the first patch mail, in this order. - `deep` threading makes every mail a reply to the previous one. - A true boolean value is the same as `shallow`, and a false - value disables threading. - -format.signOff:: - A boolean value which lets you enable the `-s/--signoff` option of - format-patch by default. *Note:* Adding the Signed-off-by: line to a - patch should be a conscious act and means that you certify you have - the rights to submit this work under the same open source license. - Please see the 'SubmittingPatches' document for further discussion. - -format.coverLetter:: - A boolean that controls whether to generate a cover-letter when - format-patch is invoked, but in addition can be set to "auto", to - generate a cover-letter only when there's more than one patch. - -format.outputDirectory:: - Set a custom directory to store the resulting files instead of the - current working directory. - -format.useAutoBase:: - A boolean value which lets you enable the `--base=auto` option of - format-patch by default. - -filter.<driver>.clean:: - The command which is used to convert the content of a worktree - file to a blob upon checkin. See linkgit:gitattributes[5] for - details. - -filter.<driver>.smudge:: - The command which is used to convert the content of a blob - object to a worktree file upon checkout. See - linkgit:gitattributes[5] for details. - -fsck.<msg-id>:: - During fsck git may find issues with legacy data which - wouldn't be generated by current versions of git, and which - wouldn't be sent over the wire if `transfer.fsckObjects` was - set. This feature is intended to support working with legacy - repositories containing such data. -+ -Setting `fsck.<msg-id>` will be picked up by linkgit:git-fsck[1], but -to accept pushes of such data set `receive.fsck.<msg-id>` instead, or -to clone or fetch it set `fetch.fsck.<msg-id>`. -+ -The rest of the documentation discusses `fsck.*` for brevity, but the -same applies for the corresponding `receive.fsck.*` and -`fetch.<msg-id>.*`. variables. -+ -Unlike variables like `color.ui` and `core.editor` the -`receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>` variables will not -fall back on the `fsck.<msg-id>` configuration if they aren't set. To -uniformly configure the same fsck settings in different circumstances -all three of them they must all set to the same values. -+ -When `fsck.<msg-id>` is set, errors can be switched to warnings and -vice versa by configuring the `fsck.<msg-id>` setting where the -`<msg-id>` is the fsck message ID and the value is one of `error`, -`warn` or `ignore`. For convenience, fsck prefixes the error/warning -with the message ID, e.g. "missingEmail: invalid author/committer line -- missing email" means that setting `fsck.missingEmail = ignore` will -hide that issue. -+ -In general, it is better to enumerate existing objects with problems -with `fsck.skipList`, instead of listing the kind of breakages these -problematic objects share to be ignored, as doing the latter will -allow new instances of the same breakages go unnoticed. -+ -Setting an unknown `fsck.<msg-id>` value will cause fsck to die, but -doing the same for `receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>` -will only cause git to warn. - -fsck.skipList:: - The path to a sorted list of object names (i.e. one SHA-1 per - line) that are known to be broken in a non-fatal way and should - be ignored. This feature is useful when an established project - should be accepted despite early commits containing errors that - can be safely ignored such as invalid committer email addresses. - Note: corrupt objects cannot be skipped with this setting. -+ -Like `fsck.<msg-id>` this variable has corresponding -`receive.fsck.skipList` and `fetch.fsck.skipList` variants. -+ -Unlike variables like `color.ui` and `core.editor` the -`receive.fsck.skipList` and `fetch.fsck.skipList` variables will not -fall back on the `fsck.skipList` configuration if they aren't set. To -uniformly configure the same fsck settings in different circumstances -all three of them they must all set to the same values. - -gc.aggressiveDepth:: - The depth parameter used in the delta compression - algorithm used by 'git gc --aggressive'. This defaults - to 50. - -gc.aggressiveWindow:: - The window size parameter used in the delta compression - algorithm used by 'git gc --aggressive'. This defaults - to 250. - -gc.auto:: - When there are approximately more than this many loose - objects in the repository, `git gc --auto` will pack them. - Some Porcelain commands use this command to perform a - light-weight garbage collection from time to time. The - default value is 6700. Setting this to 0 disables it. - -gc.autoPackLimit:: - When there are more than this many packs that are not - marked with `*.keep` file in the repository, `git gc - --auto` consolidates them into one larger pack. The - default value is 50. Setting this to 0 disables it. - -gc.autoDetach:: - Make `git gc --auto` return immediately and run in background - if the system supports it. Default is true. - -gc.bigPackThreshold:: - If non-zero, all packs larger than this limit are kept when - `git gc` is run. This is very similar to `--keep-base-pack` - except that all packs that meet the threshold are kept, not - just the base pack. Defaults to zero. Common unit suffixes of - 'k', 'm', or 'g' are supported. -+ -Note that if the number of kept packs is more than gc.autoPackLimit, -this configuration variable is ignored, all packs except the base pack -will be repacked. After this the number of packs should go below -gc.autoPackLimit and gc.bigPackThreshold should be respected again. - -gc.writeCommitGraph:: - If true, then gc will rewrite the commit-graph file when - linkgit:git-gc[1] is run. When using linkgit:git-gc[1] - '--auto' the commit-graph will be updated if housekeeping is - required. Default is false. See linkgit:git-commit-graph[1] - for details. - -gc.logExpiry:: - If the file gc.log exists, then `git gc --auto` won't run - unless that file is more than 'gc.logExpiry' old. Default is - "1.day". See `gc.pruneExpire` for more ways to specify its - value. - -gc.packRefs:: - Running `git pack-refs` in a repository renders it - unclonable by Git versions prior to 1.5.1.2 over dumb - transports such as HTTP. This variable determines whether - 'git gc' runs `git pack-refs`. This can be set to `notbare` - to enable it within all non-bare repos or it can be set to a - boolean value. The default is `true`. - -gc.pruneExpire:: - When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'. - Override the grace period with this config variable. The value - "now" may be used to disable this grace period and always prune - unreachable objects immediately, or "never" may be used to - suppress pruning. This feature helps prevent corruption when - 'git gc' runs concurrently with another process writing to the - repository; see the "NOTES" section of linkgit:git-gc[1]. - -gc.worktreePruneExpire:: - When 'git gc' is run, it calls - 'git worktree prune --expire 3.months.ago'. - This config variable can be used to set a different grace - period. The value "now" may be used to disable the grace - period and prune `$GIT_DIR/worktrees` immediately, or "never" - may be used to suppress pruning. - -gc.reflogExpire:: -gc.<pattern>.reflogExpire:: - 'git reflog expire' removes reflog entries older than - this time; defaults to 90 days. The value "now" expires all - entries immediately, and "never" suppresses expiration - altogether. With "<pattern>" (e.g. - "refs/stash") in the middle the setting applies only to - the refs that match the <pattern>. - -gc.reflogExpireUnreachable:: -gc.<pattern>.reflogExpireUnreachable:: - 'git reflog expire' removes reflog entries older than - this time and are not reachable from the current tip; - defaults to 30 days. The value "now" expires all entries - immediately, and "never" suppresses expiration altogether. - With "<pattern>" (e.g. "refs/stash") - in the middle, the setting applies only to the refs that - match the <pattern>. - -gc.rerereResolved:: - Records of conflicted merge you resolved earlier are - kept for this many days when 'git rerere gc' is run. - You can also use more human-readable "1.month.ago", etc. - The default is 60 days. See linkgit:git-rerere[1]. - -gc.rerereUnresolved:: - Records of conflicted merge you have not resolved are - kept for this many days when 'git rerere gc' is run. - You can also use more human-readable "1.month.ago", etc. - The default is 15 days. See linkgit:git-rerere[1]. - -gitcvs.commitMsgAnnotation:: - Append this string to each commit message. Set to empty string - to disable this feature. Defaults to "via git-CVS emulator". - -gitcvs.enabled:: - Whether the CVS server interface is enabled for this repository. - See linkgit:git-cvsserver[1]. - -gitcvs.logFile:: - Path to a log file where the CVS server interface well... logs - various stuff. See linkgit:git-cvsserver[1]. - -gitcvs.usecrlfattr:: - If true, the server will look up the end-of-line conversion - attributes for files to determine the `-k` modes to use. If - the attributes force Git to treat a file as text, - the `-k` mode will be left blank so CVS clients will - treat it as text. If they suppress text conversion, the file - will be set with '-kb' mode, which suppresses any newline munging - the client might otherwise do. If the attributes do not allow - the file type to be determined, then `gitcvs.allBinary` is - used. See linkgit:gitattributes[5]. - -gitcvs.allBinary:: - This is used if `gitcvs.usecrlfattr` does not resolve - the correct '-kb' mode to use. If true, all - unresolved files are sent to the client in - mode '-kb'. This causes the client to treat them - as binary files, which suppresses any newline munging it - otherwise might do. Alternatively, if it is set to "guess", - then the contents of the file are examined to decide if - it is binary, similar to `core.autocrlf`. - -gitcvs.dbName:: - Database used by git-cvsserver to cache revision information - derived from the Git repository. The exact meaning depends on the - used database driver, for SQLite (which is the default driver) this - is a filename. Supports variable substitution (see - linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`). - Default: '%Ggitcvs.%m.sqlite' - -gitcvs.dbDriver:: - Used Perl DBI driver. You can specify any available driver - for this here, but it might not work. git-cvsserver is tested - with 'DBD::SQLite', reported to work with 'DBD::Pg', and - reported *not* to work with 'DBD::mysql'. Experimental feature. - May not contain double colons (`:`). Default: 'SQLite'. - See linkgit:git-cvsserver[1]. - -gitcvs.dbUser, gitcvs.dbPass:: - Database user and password. Only useful if setting `gitcvs.dbDriver`, - since SQLite has no concept of database users and/or passwords. - 'gitcvs.dbUser' supports variable substitution (see - linkgit:git-cvsserver[1] for details). - -gitcvs.dbTableNamePrefix:: - Database table name prefix. Prepended to the names of any - database tables used, allowing a single database to be used - for several repositories. Supports variable substitution (see - linkgit:git-cvsserver[1] for details). Any non-alphabetic - characters will be replaced with underscores. - -All gitcvs variables except for `gitcvs.usecrlfattr` and -`gitcvs.allBinary` can also be specified as -'gitcvs.<access_method>.<varname>' (where 'access_method' -is one of "ext" and "pserver") to make them apply only for the given -access method. - -gitweb.category:: -gitweb.description:: -gitweb.owner:: -gitweb.url:: - See linkgit:gitweb[1] for description. - -gitweb.avatar:: -gitweb.blame:: -gitweb.grep:: -gitweb.highlight:: -gitweb.patches:: -gitweb.pickaxe:: -gitweb.remote_heads:: -gitweb.showSizes:: -gitweb.snapshot:: - See linkgit:gitweb.conf[5] for description. - -grep.lineNumber:: - If set to true, enable `-n` option by default. - -grep.column:: - If set to true, enable the `--column` option by default. - -grep.patternType:: - Set the default matching behavior. Using a value of 'basic', 'extended', - 'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`, - `--fixed-strings`, or `--perl-regexp` option accordingly, while the - value 'default' will return to the default matching behavior. - -grep.extendedRegexp:: - If set to true, enable `--extended-regexp` option by default. This - option is ignored when the `grep.patternType` option is set to a value - other than 'default'. - -grep.threads:: - Number of grep worker threads to use. - See `grep.threads` in linkgit:git-grep[1] for more information. - -grep.fallbackToNoIndex:: - If set to true, fall back to git grep --no-index if git grep - is executed outside of a git repository. Defaults to false. - -gpg.program:: - Use this custom program instead of "`gpg`" found on `$PATH` when - making or verifying a PGP signature. The program must support the - same command-line interface as GPG, namely, to verify a detached - signature, "`gpg --verify $file - <$signature`" is run, and the - program is expected to signal a good signature by exiting with - code 0, and to generate an ASCII-armored detached signature, the - standard input of "`gpg -bsau $key`" is fed with the contents to be - signed, and the program is expected to send the result to its - standard output. - -gpg.format:: - Specifies which key format to use when signing with `--gpg-sign`. - Default is "openpgp" and another possible value is "x509". - -gpg.<format>.program:: - Use this to customize the program used for the signing format you - chose. (see `gpg.program` and `gpg.format`) `gpg.program` can still - be used as a legacy synonym for `gpg.openpgp.program`. The default - value for `gpg.x509.program` is "gpgsm". - -gui.commitMsgWidth:: - Defines how wide the commit message window is in the - linkgit:git-gui[1]. "75" is the default. - -gui.diffContext:: - Specifies how many context lines should be used in calls to diff - made by the linkgit:git-gui[1]. The default is "5". - -gui.displayUntracked:: - Determines if linkgit:git-gui[1] shows untracked files - in the file list. The default is "true". - -gui.encoding:: - Specifies the default encoding to use for displaying of - file contents in linkgit:git-gui[1] and linkgit:gitk[1]. - It can be overridden by setting the 'encoding' attribute - for relevant files (see linkgit:gitattributes[5]). - If this option is not set, the tools default to the - locale encoding. - -gui.matchTrackingBranch:: - Determines if new branches created with linkgit:git-gui[1] should - default to tracking remote branches with matching names or - not. Default: "false". - -gui.newBranchTemplate:: - Is used as suggested name when creating new branches using the - linkgit:git-gui[1]. - -gui.pruneDuringFetch:: - "true" if linkgit:git-gui[1] should prune remote-tracking branches when - performing a fetch. The default value is "false". - -gui.trustmtime:: - Determines if linkgit:git-gui[1] should trust the file modification - timestamp or not. By default the timestamps are not trusted. - -gui.spellingDictionary:: - Specifies the dictionary used for spell checking commit messages in - the linkgit:git-gui[1]. When set to "none" spell checking is turned - off. - -gui.fastCopyBlame:: - If true, 'git gui blame' uses `-C` instead of `-C -C` for original - location detection. It makes blame significantly faster on huge - repositories at the expense of less thorough copy detection. - -gui.copyBlameThreshold:: - Specifies the threshold to use in 'git gui blame' original location - detection, measured in alphanumeric characters. See the - linkgit:git-blame[1] manual for more information on copy detection. - -gui.blamehistoryctx:: - Specifies the radius of history context in days to show in - linkgit:gitk[1] for the selected commit, when the `Show History - Context` menu item is invoked from 'git gui blame'. If this - variable is set to zero, the whole history is shown. - -guitool.<name>.cmd:: - Specifies the shell command line to execute when the corresponding item - of the linkgit:git-gui[1] `Tools` menu is invoked. This option is - mandatory for every tool. The command is executed from the root of - the working directory, and in the environment it receives the name of - the tool as `GIT_GUITOOL`, the name of the currently selected file as - 'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if - the head is detached, 'CUR_BRANCH' is empty). - -guitool.<name>.needsFile:: - Run the tool only if a diff is selected in the GUI. It guarantees - that 'FILENAME' is not empty. - -guitool.<name>.noConsole:: - Run the command silently, without creating a window to display its - output. - -guitool.<name>.noRescan:: - Don't rescan the working directory for changes after the tool - finishes execution. - -guitool.<name>.confirm:: - Show a confirmation dialog before actually running the tool. - -guitool.<name>.argPrompt:: - Request a string argument from the user, and pass it to the tool - through the `ARGS` environment variable. Since requesting an - argument implies confirmation, the 'confirm' option has no effect - if this is enabled. If the option is set to 'true', 'yes', or '1', - the dialog uses a built-in generic prompt; otherwise the exact - value of the variable is used. - -guitool.<name>.revPrompt:: - Request a single valid revision from the user, and set the - `REVISION` environment variable. In other aspects this option - is similar to 'argPrompt', and can be used together with it. - -guitool.<name>.revUnmerged:: - Show only unmerged branches in the 'revPrompt' subdialog. - This is useful for tools similar to merge or rebase, but not - for things like checkout or reset. - -guitool.<name>.title:: - Specifies the title to use for the prompt dialog. The default - is the tool name. - -guitool.<name>.prompt:: - Specifies the general prompt string to display at the top of - the dialog, before subsections for 'argPrompt' and 'revPrompt'. - The default value includes the actual command. - -help.browser:: - Specify the browser that will be used to display help in the - 'web' format. See linkgit:git-help[1]. - -help.format:: - Override the default help format used by linkgit:git-help[1]. - Values 'man', 'info', 'web' and 'html' are supported. 'man' is - the default. 'web' and 'html' are the same. - -help.autoCorrect:: - Automatically correct and execute mistyped commands after - waiting for the given number of deciseconds (0.1 sec). If more - than one command can be deduced from the entered text, nothing - will be executed. If the value of this option is negative, - the corrected command will be executed immediately. If the - value is 0 - the command will be just shown but not executed. - This is the default. - -help.htmlPath:: - Specify the path where the HTML documentation resides. File system paths - and URLs are supported. HTML pages will be prefixed with this path when - help is displayed in the 'web' format. This defaults to the documentation - path of your Git installation. - -http.proxy:: - Override the HTTP proxy, normally configured using the 'http_proxy', - 'https_proxy', and 'all_proxy' environment variables (see `curl(1)`). In - addition to the syntax understood by curl, it is possible to specify a - proxy string with a user name but no password, in which case git will - attempt to acquire one in the same way it does for other credentials. See - linkgit:gitcredentials[7] for more information. The syntax thus is - '[protocol://][user[:password]@]proxyhost[:port]'. This can be overridden - on a per-remote basis; see remote.<name>.proxy - -http.proxyAuthMethod:: - Set the method with which to authenticate against the HTTP proxy. This - only takes effect if the configured proxy string contains a user name part - (i.e. is of the form 'user@host' or 'user@host:port'). This can be - overridden on a per-remote basis; see `remote.<name>.proxyAuthMethod`. - Both can be overridden by the `GIT_HTTP_PROXY_AUTHMETHOD` environment - variable. Possible values are: -+ --- -* `anyauth` - Automatically pick a suitable authentication method. It is - assumed that the proxy answers an unauthenticated request with a 407 - status code and one or more Proxy-authenticate headers with supported - authentication methods. This is the default. -* `basic` - HTTP Basic authentication -* `digest` - HTTP Digest authentication; this prevents the password from being - transmitted to the proxy in clear text -* `negotiate` - GSS-Negotiate authentication (compare the --negotiate option - of `curl(1)`) -* `ntlm` - NTLM authentication (compare the --ntlm option of `curl(1)`) --- - -http.emptyAuth:: - Attempt authentication without seeking a username or password. This - can be used to attempt GSS-Negotiate authentication without specifying - a username in the URL, as libcurl normally requires a username for - authentication. - -http.delegation:: - Control GSSAPI credential delegation. The delegation is disabled - by default in libcurl since version 7.21.7. Set parameter to tell - the server what it is allowed to delegate when it comes to user - credentials. Used with GSS/kerberos. Possible values are: -+ --- -* `none` - Don't allow any delegation. -* `policy` - Delegates if and only if the OK-AS-DELEGATE flag is set in the - Kerberos service ticket, which is a matter of realm policy. -* `always` - Unconditionally allow the server to delegate. --- - - -http.extraHeader:: - Pass an additional HTTP header when communicating with a server. If - more than one such entry exists, all of them are added as extra - headers. To allow overriding the settings inherited from the system - config, an empty value will reset the extra headers to the empty list. - -http.cookieFile:: - The pathname of a file containing previously stored cookie lines, - which should be used - in the Git http session, if they match the server. The file format - of the file to read cookies from should be plain HTTP headers or - the Netscape/Mozilla cookie file format (see `curl(1)`). - NOTE that the file specified with http.cookieFile is used only as - input unless http.saveCookies is set. - -http.saveCookies:: - If set, store cookies received during requests to the file specified by - http.cookieFile. Has no effect if http.cookieFile is unset. - -http.sslVersion:: - The SSL version to use when negotiating an SSL connection, if you - want to force the default. The available and default version - depend on whether libcurl was built against NSS or OpenSSL and the - particular configuration of the crypto library in use. Internally - this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl - documentation for more details on the format of this option and - for the ssl version supported. Actually the possible values of - this option are: - - - sslv2 - - sslv3 - - tlsv1 - - tlsv1.0 - - tlsv1.1 - - tlsv1.2 - - tlsv1.3 +include::config/add.txt[] -+ -Can be overridden by the `GIT_SSL_VERSION` environment variable. -To force git to use libcurl's default ssl version and ignore any -explicit http.sslversion option, set `GIT_SSL_VERSION` to the -empty string. - -http.sslCipherList:: - A list of SSL ciphers to use when negotiating an SSL connection. - The available ciphers depend on whether libcurl was built against - NSS or OpenSSL and the particular configuration of the crypto - library in use. Internally this sets the 'CURLOPT_SSL_CIPHER_LIST' - option; see the libcurl documentation for more details on the format - of this list. -+ -Can be overridden by the `GIT_SSL_CIPHER_LIST` environment variable. -To force git to use libcurl's default cipher list and ignore any -explicit http.sslCipherList option, set `GIT_SSL_CIPHER_LIST` to the -empty string. - -http.sslVerify:: - Whether to verify the SSL certificate when fetching or pushing - over HTTPS. Defaults to true. Can be overridden by the - `GIT_SSL_NO_VERIFY` environment variable. - -http.sslCert:: - File containing the SSL certificate when fetching or pushing - over HTTPS. Can be overridden by the `GIT_SSL_CERT` environment - variable. - -http.sslKey:: - File containing the SSL private key when fetching or pushing - over HTTPS. Can be overridden by the `GIT_SSL_KEY` environment - variable. - -http.sslCertPasswordProtected:: - Enable Git's password prompt for the SSL certificate. Otherwise - OpenSSL will prompt the user, possibly many times, if the - certificate or private key is encrypted. Can be overridden by the - `GIT_SSL_CERT_PASSWORD_PROTECTED` environment variable. - -http.sslCAInfo:: - File containing the certificates to verify the peer with when - fetching or pushing over HTTPS. Can be overridden by the - `GIT_SSL_CAINFO` environment variable. - -http.sslCAPath:: - Path containing files with the CA certificates to verify the peer - with when fetching or pushing over HTTPS. Can be overridden - by the `GIT_SSL_CAPATH` environment variable. - -http.pinnedpubkey:: - Public key of the https service. It may either be the filename of - a PEM or DER encoded public key file or a string starting with - 'sha256//' followed by the base64 encoded sha256 hash of the - public key. See also libcurl 'CURLOPT_PINNEDPUBLICKEY'. git will - exit with an error if this option is set but not supported by - cURL. - -http.sslTry:: - Attempt to use AUTH SSL/TLS and encrypted data transfers - when connecting via regular FTP protocol. This might be needed - if the FTP server requires it for security reasons or you wish - to connect securely whenever remote FTP server supports it. - Default is false since it might trigger certificate verification - errors on misconfigured servers. - -http.maxRequests:: - How many HTTP requests to launch in parallel. Can be overridden - by the `GIT_HTTP_MAX_REQUESTS` environment variable. Default is 5. - -http.minSessions:: - The number of curl sessions (counted across slots) to be kept across - requests. They will not be ended with curl_easy_cleanup() until - http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this - value will be capped at 1. Defaults to 1. - -http.postBuffer:: - Maximum size in bytes of the buffer used by smart HTTP - transports when POSTing data to the remote system. - For requests larger than this buffer size, HTTP/1.1 and - Transfer-Encoding: chunked is used to avoid creating a - massive pack file locally. Default is 1 MiB, which is - sufficient for most requests. - -http.lowSpeedLimit, http.lowSpeedTime:: - If the HTTP transfer speed is less than 'http.lowSpeedLimit' - for longer than 'http.lowSpeedTime' seconds, the transfer is aborted. - Can be overridden by the `GIT_HTTP_LOW_SPEED_LIMIT` and - `GIT_HTTP_LOW_SPEED_TIME` environment variables. - -http.noEPSV:: - A boolean which disables using of EPSV ftp command by curl. - This can helpful with some "poor" ftp servers which don't - support EPSV mode. Can be overridden by the `GIT_CURL_FTP_NO_EPSV` - environment variable. Default is false (curl will use EPSV). - -http.userAgent:: - The HTTP USER_AGENT string presented to an HTTP server. The default - value represents the version of the client Git such as git/1.7.1. - This option allows you to override this value to a more common value - such as Mozilla/4.0. This may be necessary, for instance, if - connecting through a firewall that restricts HTTP connections to a set - of common USER_AGENT strings (but not including those like git/1.7.1). - Can be overridden by the `GIT_HTTP_USER_AGENT` environment variable. - -http.followRedirects:: - Whether git should follow HTTP redirects. If set to `true`, git - will transparently follow any redirect issued by a server it - encounters. If set to `false`, git will treat all redirects as - errors. If set to `initial`, git will follow redirects only for - the initial request to a remote, but not for subsequent - follow-up HTTP requests. Since git uses the redirected URL as - the base for the follow-up requests, this is generally - sufficient. The default is `initial`. - -http.<url>.*:: - Any of the http.* options above can be applied selectively to some URLs. - For a config key to match a URL, each element of the config key is - compared to that of the URL, in the following order: -+ --- -. Scheme (e.g., `https` in `https://example.com/`). This field - must match exactly between the config key and the URL. - -. Host/domain name (e.g., `example.com` in `https://example.com/`). - This field must match between the config key and the URL. It is - possible to specify a `*` as part of the host name to match all subdomains - at this level. `https://*.example.com/` for example would match - `https://foo.example.com/`, but not `https://foo.bar.example.com/`. - -. Port number (e.g., `8080` in `http://example.com:8080/`). - This field must match exactly between the config key and the URL. - Omitted port numbers are automatically converted to the correct - default for the scheme before matching. - -. Path (e.g., `repo.git` in `https://example.com/repo.git`). The - path field of the config key must match the path field of the URL - either exactly or as a prefix of slash-delimited path elements. This means - a config key with path `foo/` matches URL path `foo/bar`. A prefix can only - match on a slash (`/`) boundary. Longer matches take precedence (so a config - key with path `foo/bar` is a better match to URL path `foo/bar` than a config - key with just path `foo/`). - -. User name (e.g., `user` in `https://user@example.com/repo.git`). If - the config key has a user name it must match the user name in the - URL exactly. If the config key does not have a user name, that - config key will match a URL with any user name (including none), - but at a lower precedence than a config key with a user name. --- -+ -The list above is ordered by decreasing precedence; a URL that matches -a config key's path is preferred to one that matches its user name. For example, -if the URL is `https://user@example.com/foo/bar` a config key match of -`https://example.com/foo` will be preferred over a config key match of -`https://user@example.com`. -+ -All URLs are normalized before attempting any matching (the password part, -if embedded in the URL, is always ignored for matching purposes) so that -equivalent URLs that are simply spelled differently will match properly. -Environment variable settings always override any matches. The URLs that are -matched against are those given directly to Git commands. This means any URLs -visited as a result of a redirection do not participate in matching. - -ssh.variant:: - By default, Git determines the command line arguments to use - based on the basename of the configured SSH command (configured - using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or - the config setting `core.sshCommand`). If the basename is - unrecognized, Git will attempt to detect support of OpenSSH - options by first invoking the configured SSH command with the - `-G` (print configuration) option and will subsequently use - OpenSSH options (if that is successful) or no options besides - the host and remote command (if it fails). -+ -The config variable `ssh.variant` can be set to override this detection. -Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`, -`tortoiseplink`, `simple` (no options except the host and remote command). -The default auto-detection can be explicitly requested using the value -`auto`. Any other value is treated as `ssh`. This setting can also be -overridden via the environment variable `GIT_SSH_VARIANT`. -+ -The current command-line parameters used for each variant are as -follows: -+ --- +include::config/alias.txt[] -* `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command +include::config/am.txt[] -* `simple` - [username@]host command +include::config/apply.txt[] -* `plink` or `putty` - [-P port] [-4] [-6] [username@]host command +include::config/blame.txt[] -* `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command +include::config/branch.txt[] --- -+ -Except for the `simple` variant, command-line parameters are likely to -change as git gains new features. - -i18n.commitEncoding:: - Character encoding the commit messages are stored in; Git itself - does not care per se, but this information is necessary e.g. when - importing commits from emails or in the gitk graphical history - browser (and possibly at other places in the future or in other - porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'. - -i18n.logOutputEncoding:: - Character encoding the commit messages are converted to when - running 'git log' and friends. - -imap:: - The configuration variables in the 'imap' section are described - in linkgit:git-imap-send[1]. - -index.version:: - Specify the version with which new index files should be - initialized. This does not affect existing repositories. - -init.templateDir:: - Specify the directory from which templates will be copied. - (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].) - -instaweb.browser:: - Specify the program that will be used to browse your working - repository in gitweb. See linkgit:git-instaweb[1]. - -instaweb.httpd:: - The HTTP daemon command-line to start gitweb on your working - repository. See linkgit:git-instaweb[1]. - -instaweb.local:: - If true the web server started by linkgit:git-instaweb[1] will - be bound to the local IP (127.0.0.1). - -instaweb.modulePath:: - The default module path for linkgit:git-instaweb[1] to use - instead of /usr/lib/apache2/modules. Only used if httpd - is Apache. - -instaweb.port:: - The port number to bind the gitweb httpd to. See - linkgit:git-instaweb[1]. - -interactive.singleKey:: - In interactive commands, allow the user to provide one-letter - input with a single key (i.e., without hitting enter). - Currently this is used by the `--patch` mode of - linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1], - linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this - setting is silently ignored if portable keystroke input - is not available; requires the Perl module Term::ReadKey. - -interactive.diffFilter:: - When an interactive command (such as `git add --patch`) shows - a colorized diff, git will pipe the diff through the shell - command defined by this configuration variable. The command may - mark up the diff further for human consumption, provided that it - retains a one-to-one correspondence with the lines in the - original diff. Defaults to disabled (no filtering). - -log.abbrevCommit:: - If true, makes linkgit:git-log[1], linkgit:git-show[1], and - linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may - override this option with `--no-abbrev-commit`. - -log.date:: - Set the default date-time mode for the 'log' command. - Setting a value for log.date is similar to using 'git log''s - `--date` option. See linkgit:git-log[1] for details. - -log.decorate:: - Print out the ref names of any commits that are shown by the log - command. If 'short' is specified, the ref name prefixes 'refs/heads/', - 'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is - specified, the full ref name (including prefix) will be printed. - If 'auto' is specified, then if the output is going to a terminal, - the ref names are shown as if 'short' were given, otherwise no ref - names are shown. This is the same as the `--decorate` option - of the `git log`. - -log.follow:: - If `true`, `git log` will act as if the `--follow` option was used when - a single <path> is given. This has the same limitations as `--follow`, - i.e. it cannot be used to follow multiple files and does not work well - on non-linear history. - -log.graphColors:: - A list of colors, separated by commas, that can be used to draw - history lines in `git log --graph`. - -log.showRoot:: - If true, the initial commit will be shown as a big creation event. - This is equivalent to a diff against an empty tree. - Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which - normally hide the root commit will now show it. True by default. - -log.showSignature:: - If true, makes linkgit:git-log[1], linkgit:git-show[1], and - linkgit:git-whatchanged[1] assume `--show-signature`. - -log.mailmap:: - If true, makes linkgit:git-log[1], linkgit:git-show[1], and - linkgit:git-whatchanged[1] assume `--use-mailmap`. - -mailinfo.scissors:: - If true, makes linkgit:git-mailinfo[1] (and therefore - linkgit:git-am[1]) act by default as if the --scissors option - was provided on the command-line. When active, this features - removes everything from the message body before a scissors - line (i.e. consisting mainly of ">8", "8<" and "-"). - -mailmap.file:: - The location of an augmenting mailmap file. The default - mailmap, located in the root of the repository, is loaded - first, then the mailmap file pointed to by this variable. - The location of the mailmap file may be in a repository - subdirectory, or somewhere outside of the repository itself. - See linkgit:git-shortlog[1] and linkgit:git-blame[1]. - -mailmap.blob:: - Like `mailmap.file`, but consider the value as a reference to a - blob in the repository. If both `mailmap.file` and - `mailmap.blob` are given, both are parsed, with entries from - `mailmap.file` taking precedence. In a bare repository, this - defaults to `HEAD:.mailmap`. In a non-bare repository, it - defaults to empty. - -man.viewer:: - Specify the programs that may be used to display help in the - 'man' format. See linkgit:git-help[1]. - -man.<tool>.cmd:: - Specify the command to invoke the specified man viewer. The - specified command is evaluated in shell with the man page - passed as argument. (See linkgit:git-help[1].) - -man.<tool>.path:: - Override the path for the given tool that may be used to - display help in the 'man' format. See linkgit:git-help[1]. - -include::merge-config.txt[] - -mergetool.<tool>.path:: - Override the path for the given tool. This is useful in case - your tool is not in the PATH. - -mergetool.<tool>.cmd:: - Specify the command to invoke the specified merge tool. The - specified command is evaluated in shell with the following - variables available: 'BASE' is the name of a temporary file - containing the common base of the files to be merged, if available; - 'LOCAL' is the name of a temporary file containing the contents of - the file on the current branch; 'REMOTE' is the name of a temporary - file containing the contents of the file from the branch being - merged; 'MERGED' contains the name of the file to which the merge - tool should write the results of a successful merge. - -mergetool.<tool>.trustExitCode:: - For a custom merge command, specify whether the exit code of - the merge command can be used to determine whether the merge was - successful. If this is not set to true then the merge target file - timestamp is checked and the merge assumed to have been successful - if the file has been updated, otherwise the user is prompted to - indicate the success of the merge. - -mergetool.meld.hasOutput:: - Older versions of `meld` do not support the `--output` option. - Git will attempt to detect whether `meld` supports `--output` - by inspecting the output of `meld --help`. Configuring - `mergetool.meld.hasOutput` will make Git skip these checks and - use the configured value instead. Setting `mergetool.meld.hasOutput` - to `true` tells Git to unconditionally use the `--output` option, - and `false` avoids using `--output`. - -mergetool.keepBackup:: - After performing a merge, the original file with conflict markers - can be saved as a file with a `.orig` extension. If this variable - is set to `false` then this file is not preserved. Defaults to - `true` (i.e. keep the backup files). - -mergetool.keepTemporaries:: - When invoking a custom merge tool, Git uses a set of temporary - files to pass to the tool. If the tool returns an error and this - variable is set to `true`, then these temporary files will be - preserved, otherwise they will be removed after the tool has - exited. Defaults to `false`. - -mergetool.writeToTemp:: - Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of - conflicting files in the worktree by default. Git will attempt - to use a temporary directory for these files when set `true`. - Defaults to `false`. - -mergetool.prompt:: - Prompt before each invocation of the merge resolution program. - -notes.mergeStrategy:: - Which merge strategy to choose by default when resolving notes - conflicts. Must be one of `manual`, `ours`, `theirs`, `union`, or - `cat_sort_uniq`. Defaults to `manual`. See "NOTES MERGE STRATEGIES" - section of linkgit:git-notes[1] for more information on each strategy. - -notes.<name>.mergeStrategy:: - Which merge strategy to choose when doing a notes merge into - refs/notes/<name>. This overrides the more general - "notes.mergeStrategy". See the "NOTES MERGE STRATEGIES" section in - linkgit:git-notes[1] for more information on the available strategies. - -notes.displayRef:: - The (fully qualified) refname from which to show notes when - showing commit messages. The value of this variable can be set - to a glob, in which case notes from all matching refs will be - shown. You may also specify this configuration variable - several times. A warning will be issued for refs that do not - exist, but a glob that does not match any refs is silently - ignored. -+ -This setting can be overridden with the `GIT_NOTES_DISPLAY_REF` -environment variable, which must be a colon separated list of refs or -globs. -+ -The effective value of "core.notesRef" (possibly overridden by -GIT_NOTES_REF) is also implicitly added to the list of refs to be -displayed. - -notes.rewrite.<command>:: - When rewriting commits with <command> (currently `amend` or - `rebase`) and this variable is set to `true`, Git - automatically copies your notes from the original to the - rewritten commit. Defaults to `true`, but see - "notes.rewriteRef" below. - -notes.rewriteMode:: - When copying notes during a rewrite (see the - "notes.rewrite.<command>" option), determines what to do if - the target commit already has a note. Must be one of - `overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`. - Defaults to `concatenate`. -+ -This setting can be overridden with the `GIT_NOTES_REWRITE_MODE` -environment variable. - -notes.rewriteRef:: - When copying notes during a rewrite, specifies the (fully - qualified) ref whose notes should be copied. The ref may be a - glob, in which case notes in all matching refs will be copied. - You may also specify this configuration several times. -+ -Does not have a default value; you must configure this variable to -enable note rewriting. Set it to `refs/notes/commits` to enable -rewriting for the default commit notes. -+ -This setting can be overridden with the `GIT_NOTES_REWRITE_REF` -environment variable, which must be a colon separated list of refs or -globs. - -pack.window:: - The size of the window used by linkgit:git-pack-objects[1] when no - window size is given on the command line. Defaults to 10. - -pack.depth:: - The maximum delta depth used by linkgit:git-pack-objects[1] when no - maximum depth is given on the command line. Defaults to 50. - Maximum value is 4095. - -pack.windowMemory:: - The maximum size of memory that is consumed by each thread - in linkgit:git-pack-objects[1] for pack window memory when - no limit is given on the command line. The value can be - suffixed with "k", "m", or "g". When left unconfigured (or - set explicitly to 0), there will be no limit. - -pack.compression:: - An integer -1..9, indicating the compression level for objects - in a pack file. -1 is the zlib default. 0 means no - compression, and 1..9 are various speed/size tradeoffs, 9 being - slowest. If not set, defaults to core.compression. If that is - not set, defaults to -1, the zlib default, which is "a default - compromise between speed and compression (currently equivalent - to level 6)." -+ -Note that changing the compression level will not automatically recompress -all existing objects. You can force recompression by passing the -F option -to linkgit:git-repack[1]. - -pack.island:: - An extended regular expression configuring a set of delta - islands. See "DELTA ISLANDS" in linkgit:git-pack-objects[1] - for details. - -pack.islandCore:: - Specify an island name which gets to have its objects be - packed first. This creates a kind of pseudo-pack at the front - of one pack, so that the objects from the specified island are - hopefully faster to copy into any pack that should be served - to a user requesting these objects. In practice this means - that the island specified should likely correspond to what is - the most commonly cloned in the repo. See also "DELTA ISLANDS" - in linkgit:git-pack-objects[1]. - -pack.deltaCacheSize:: - The maximum memory in bytes used for caching deltas in - linkgit:git-pack-objects[1] before writing them out to a pack. - This cache is used to speed up the writing object phase by not - having to recompute the final delta result once the best match - for all objects is found. Repacking large repositories on machines - which are tight with memory might be badly impacted by this though, - especially if this cache pushes the system into swapping. - A value of 0 means no limit. The smallest size of 1 byte may be - used to virtually disable this cache. Defaults to 256 MiB. - -pack.deltaCacheLimit:: - The maximum size of a delta, that is cached in - linkgit:git-pack-objects[1]. This cache is used to speed up the - writing object phase by not having to recompute the final delta - result once the best match for all objects is found. - Defaults to 1000. Maximum value is 65535. - -pack.threads:: - Specifies the number of threads to spawn when searching for best - delta matches. This requires that linkgit:git-pack-objects[1] - be compiled with pthreads otherwise this option is ignored with a - warning. This is meant to reduce packing time on multiprocessor - machines. The required amount of memory for the delta search window - is however multiplied by the number of threads. - Specifying 0 will cause Git to auto-detect the number of CPU's - and set the number of threads accordingly. - -pack.indexVersion:: - Specify the default pack index version. Valid values are 1 for - legacy pack index used by Git versions prior to 1.5.2, and 2 for - the new pack index with capabilities for packs larger than 4 GB - as well as proper protection against the repacking of corrupted - packs. Version 2 is the default. Note that version 2 is enforced - and this config option ignored whenever the corresponding pack is - larger than 2 GB. -+ -If you have an old Git that does not understand the version 2 `*.idx` file, -cloning or fetching over a non native protocol (e.g. "http") -that will copy both `*.pack` file and corresponding `*.idx` file from the -other side may give you a repository that cannot be accessed with your -older version of Git. If the `*.pack` file is smaller than 2 GB, however, -you can use linkgit:git-index-pack[1] on the *.pack file to regenerate -the `*.idx` file. - -pack.packSizeLimit:: - The maximum size of a pack. This setting only affects - packing to a file when repacking, i.e. the git:// protocol - is unaffected. It can be overridden by the `--max-pack-size` - option of linkgit:git-repack[1]. Reaching this limit results - in the creation of multiple packfiles; which in turn prevents - bitmaps from being created. - The minimum size allowed is limited to 1 MiB. - The default is unlimited. - Common unit suffixes of 'k', 'm', or 'g' are - supported. - -pack.useBitmaps:: - When true, git will use pack bitmaps (if available) when packing - to stdout (e.g., during the server side of a fetch). Defaults to - true. You should not generally need to turn this off unless - you are debugging pack bitmaps. - -pack.writeBitmaps (deprecated):: - This is a deprecated synonym for `repack.writeBitmaps`. - -pack.writeBitmapHashCache:: - When true, git will include a "hash cache" section in the bitmap - index (if one is written). This cache can be used to feed git's - delta heuristics, potentially leading to better deltas between - bitmapped and non-bitmapped objects (e.g., when serving a fetch - between an older, bitmapped pack and objects that have been - pushed since the last gc). The downside is that it consumes 4 - bytes per object of disk space, and that JGit's bitmap - implementation does not understand it, causing it to complain if - Git and JGit are used on the same repository. Defaults to false. - -pager.<cmd>:: - If the value is boolean, turns on or off pagination of the - output of a particular Git subcommand when writing to a tty. - Otherwise, turns on pagination for the subcommand using the - pager specified by the value of `pager.<cmd>`. If `--paginate` - or `--no-pager` is specified on the command line, it takes - precedence over this option. To disable pagination for all - commands, set `core.pager` or `GIT_PAGER` to `cat`. - -pretty.<name>:: - Alias for a --pretty= format string, as specified in - linkgit:git-log[1]. Any aliases defined here can be used just - as the built-in pretty formats could. For example, - running `git config pretty.changelog "format:* %H %s"` - would cause the invocation `git log --pretty=changelog` - to be equivalent to running `git log "--pretty=format:* %H %s"`. - Note that an alias with the same name as a built-in format - will be silently ignored. - -protocol.allow:: - If set, provide a user defined default policy for all protocols which - don't explicitly have a policy (`protocol.<name>.allow`). By default, - if unset, known-safe protocols (http, https, git, ssh, file) have a - default policy of `always`, known-dangerous protocols (ext) have a - default policy of `never`, and all other protocols have a default - policy of `user`. Supported policies: -+ --- +include::config/browser.txt[] -* `always` - protocol is always able to be used. +include::config/checkout.txt[] -* `never` - protocol is never able to be used. +include::config/clean.txt[] -* `user` - protocol is only able to be used when `GIT_PROTOCOL_FROM_USER` is - either unset or has a value of 1. This policy should be used when you want a - protocol to be directly usable by the user but don't want it used by commands which - execute clone/fetch/push commands without user input, e.g. recursive - submodule initialization. +include::config/color.txt[] --- +include::config/column.txt[] -protocol.<name>.allow:: - Set a policy to be used by protocol `<name>` with clone/fetch/push - commands. See `protocol.allow` above for the available policies. -+ -The protocol names currently used by git are: -+ --- - - `file`: any local file-based path (including `file://` URLs, - or local paths) - - - `git`: the anonymous git protocol over a direct TCP - connection (or proxy, if configured) - - - `ssh`: git over ssh (including `host:path` syntax, - `ssh://`, etc). - - - `http`: git over http, both "smart http" and "dumb http". - Note that this does _not_ include `https`; if you want to configure - both, you must do so individually. - - - any external helpers are named by their protocol (e.g., use - `hg` to allow the `git-remote-hg` helper) --- - -protocol.version:: - Experimental. If set, clients will attempt to communicate with a - server using the specified protocol version. If unset, no - attempt will be made by the client to communicate using a - particular protocol version, this results in protocol version 0 - being used. - Supported versions: -+ --- +include::config/commit.txt[] -* `0` - the original wire protocol. +include::config/credential.txt[] -* `1` - the original wire protocol with the addition of a version string - in the initial response from the server. +include::config/completion.txt[] -* `2` - link:technical/protocol-v2.html[wire protocol version 2]. +include::config/diff.txt[] --- +include::config/difftool.txt[] -pull.ff:: - By default, Git does not create an extra merge commit when merging - a commit that is a descendant of the current commit. Instead, the - tip of the current branch is fast-forwarded. When set to `false`, - this variable tells Git to create an extra merge commit in such - a case (equivalent to giving the `--no-ff` option from the command - line). When set to `only`, only such fast-forward merges are - allowed (equivalent to giving the `--ff-only` option from the - command line). This setting overrides `merge.ff` when pulling. +include::config/fastimport.txt[] -pull.rebase:: - When true, rebase branches on top of the fetched branch, instead - of merging the default branch from the default remote when "git - pull" is run. See "branch.<name>.rebase" for setting this on a - per-branch basis. -+ -When `merges`, pass the `--rebase-merges` option to 'git rebase' -so that the local merge commits are included in the rebase (see -linkgit:git-rebase[1] for details). -+ -When preserve, also pass `--preserve-merges` along to 'git rebase' -so that locally committed merge commits will not be flattened -by running 'git pull'. -+ -When the value is `interactive`, the rebase is run in interactive mode. -+ -*NOTE*: this is a possibly dangerous operation; do *not* use -it unless you understand the implications (see linkgit:git-rebase[1] -for details). - -pull.octopus:: - The default merge strategy to use when pulling multiple branches - at once. - -pull.twohead:: - The default merge strategy to use when pulling a single branch. - -push.default:: - Defines the action `git push` should take if no refspec is - explicitly given. Different values are well-suited for - specific workflows; for instance, in a purely central workflow - (i.e. the fetch source is equal to the push destination), - `upstream` is probably what you want. Possible values are: -+ --- +include::config/fetch.txt[] -* `nothing` - do not push anything (error out) unless a refspec is - explicitly given. This is primarily meant for people who want to - avoid mistakes by always being explicit. +include::config/format.txt[] -* `current` - push the current branch to update a branch with the same - name on the receiving end. Works in both central and non-central - workflows. +include::config/filter.txt[] -* `upstream` - push the current branch back to the branch whose - changes are usually integrated into the current branch (which is - called `@{upstream}`). This mode only makes sense if you are - pushing to the same repository you would normally pull from - (i.e. central workflow). +include::config/fsck.txt[] -* `tracking` - This is a deprecated synonym for `upstream`. +include::config/gc.txt[] -* `simple` - in centralized workflow, work like `upstream` with an - added safety to refuse to push if the upstream branch's name is - different from the local one. -+ -When pushing to a remote that is different from the remote you normally -pull from, work as `current`. This is the safest option and is suited -for beginners. -+ -This mode has become the default in Git 2.0. - -* `matching` - push all branches having the same name on both ends. - This makes the repository you are pushing to remember the set of - branches that will be pushed out (e.g. if you always push 'maint' - and 'master' there and no other branches, the repository you push - to will have these two branches, and your local 'maint' and - 'master' will be pushed there). -+ -To use this mode effectively, you have to make sure _all_ the -branches you would push out are ready to be pushed out before -running 'git push', as the whole point of this mode is to allow you -to push all of the branches in one go. If you usually finish work -on only one branch and push out the result, while other branches are -unfinished, this mode is not for you. Also this mode is not -suitable for pushing into a shared central repository, as other -people may add new branches there, or update the tip of existing -branches outside your control. -+ -This used to be the default, but not since Git 2.0 (`simple` is the -new default). - --- - -push.followTags:: - If set to true enable `--follow-tags` option by default. You - may override this configuration at time of push by specifying - `--no-follow-tags`. - -push.gpgSign:: - May be set to a boolean value, or the string 'if-asked'. A true - value causes all pushes to be GPG signed, as if `--signed` is - passed to linkgit:git-push[1]. The string 'if-asked' causes - pushes to be signed if the server supports it, as if - `--signed=if-asked` is passed to 'git push'. A false value may - override a value from a lower-priority config file. An explicit - command-line flag always overrides this config option. - -push.pushOption:: - When no `--push-option=<option>` argument is given from the - command line, `git push` behaves as if each <value> of - this variable is given as `--push-option=<value>`. -+ -This is a multi-valued variable, and an empty value can be used in a -higher priority configuration file (e.g. `.git/config` in a -repository) to clear the values inherited from a lower priority -configuration files (e.g. `$HOME/.gitconfig`). -+ --- - -Example: - -/etc/gitconfig - push.pushoption = a - push.pushoption = b - -~/.gitconfig - push.pushoption = c - -repo/.git/config - push.pushoption = - push.pushoption = b - -This will result in only b (a and c are cleared). - --- - -push.recurseSubmodules:: - Make sure all submodule commits used by the revisions to be pushed - are available on a remote-tracking branch. If the value is 'check' - then Git will verify that all submodule commits that changed in the - revisions to be pushed are available on at least one remote of the - submodule. If any commits are missing, the push will be aborted and - exit with non-zero status. If the value is 'on-demand' then all - submodules that changed in the revisions to be pushed will be - pushed. If on-demand was not able to push all necessary revisions - it will also be aborted and exit with non-zero status. If the value - is 'no' then default behavior of ignoring submodules when pushing - is retained. You may override this configuration at time of push by - specifying '--recurse-submodules=check|on-demand|no'. - -include::rebase-config.txt[] - -receive.advertiseAtomic:: - By default, git-receive-pack will advertise the atomic push - capability to its clients. If you don't want to advertise this - capability, set this variable to false. - -receive.advertisePushOptions:: - When set to true, git-receive-pack will advertise the push options - capability to its clients. False by default. - -receive.autogc:: - By default, git-receive-pack will run "git-gc --auto" after - receiving data from git-push and updating refs. You can stop - it by setting this variable to false. - -receive.certNonceSeed:: - By setting this variable to a string, `git receive-pack` - will accept a `git push --signed` and verifies it by using - a "nonce" protected by HMAC using this string as a secret - key. - -receive.certNonceSlop:: - When a `git push --signed` sent a push certificate with a - "nonce" that was issued by a receive-pack serving the same - repository within this many seconds, export the "nonce" - found in the certificate to `GIT_PUSH_CERT_NONCE` to the - hooks (instead of what the receive-pack asked the sending - side to include). This may allow writing checks in - `pre-receive` and `post-receive` a bit easier. Instead of - checking `GIT_PUSH_CERT_NONCE_SLOP` environment variable - that records by how many seconds the nonce is stale to - decide if they want to accept the certificate, they only - can check `GIT_PUSH_CERT_NONCE_STATUS` is `OK`. - -receive.fsckObjects:: - If it is set to true, git-receive-pack will check all received - objects. See `transfer.fsckObjects` for what's checked. - Defaults to false. If not set, the value of - `transfer.fsckObjects` is used instead. - -receive.fsck.<msg-id>:: - Acts like `fsck.<msg-id>`, but is used by - linkgit:git-receive-pack[1] instead of - linkgit:git-fsck[1]. See the `fsck.<msg-id>` documentation for - details. - -receive.fsck.skipList:: - Acts like `fsck.skipList`, but is used by - linkgit:git-receive-pack[1] instead of - linkgit:git-fsck[1]. See the `fsck.skipList` documentation for - details. - -receive.keepAlive:: - After receiving the pack from the client, `receive-pack` may - produce no output (if `--quiet` was specified) while processing - the pack, causing some networks to drop the TCP connection. - With this option set, if `receive-pack` does not transmit - any data in this phase for `receive.keepAlive` seconds, it will - send a short keepalive packet. The default is 5 seconds; set - to 0 to disable keepalives entirely. - -receive.unpackLimit:: - If the number of objects received in a push is below this - limit then the objects will be unpacked into loose object - files. However if the number of received objects equals or - exceeds this limit then the received pack will be stored as - a pack, after adding any missing delta bases. Storing the - pack from a push can make the push operation complete faster, - especially on slow filesystems. If not set, the value of - `transfer.unpackLimit` is used instead. - -receive.maxInputSize:: - If the size of the incoming pack stream is larger than this - limit, then git-receive-pack will error out, instead of - accepting the pack file. If not set or set to 0, then the size - is unlimited. - -receive.denyDeletes:: - If set to true, git-receive-pack will deny a ref update that deletes - the ref. Use this to prevent such a ref deletion via a push. - -receive.denyDeleteCurrent:: - If set to true, git-receive-pack will deny a ref update that - deletes the currently checked out branch of a non-bare repository. - -receive.denyCurrentBranch:: - If set to true or "refuse", git-receive-pack will deny a ref update - to the currently checked out branch of a non-bare repository. - Such a push is potentially dangerous because it brings the HEAD - out of sync with the index and working tree. If set to "warn", - print a warning of such a push to stderr, but allow the push to - proceed. If set to false or "ignore", allow such pushes with no - message. Defaults to "refuse". -+ -Another option is "updateInstead" which will update the working -tree if pushing into the current branch. This option is -intended for synchronizing working directories when one side is not easily -accessible via interactive ssh (e.g. a live web site, hence the requirement -that the working directory be clean). This mode also comes in handy when -developing inside a VM to test and fix code on different Operating Systems. -+ -By default, "updateInstead" will refuse the push if the working tree or -the index have any difference from the HEAD, but the `push-to-checkout` -hook can be used to customize this. See linkgit:githooks[5]. - -receive.denyNonFastForwards:: - If set to true, git-receive-pack will deny a ref update which is - not a fast-forward. Use this to prevent such an update via a push, - even if that push is forced. This configuration variable is - set when initializing a shared repository. - -receive.hideRefs:: - This variable is the same as `transfer.hideRefs`, but applies - only to `receive-pack` (and so affects pushes, but not fetches). - An attempt to update or delete a hidden ref by `git push` is - rejected. - -receive.updateServerInfo:: - If set to true, git-receive-pack will run git-update-server-info - after receiving data from git-push and updating refs. - -receive.shallowUpdate:: - If set to true, .git/shallow can be updated when new refs - require new shallow roots. Otherwise those refs are rejected. - -remote.pushDefault:: - The remote to push to by default. Overrides - `branch.<name>.remote` for all branches, and is overridden by - `branch.<name>.pushRemote` for specific branches. - -remote.<name>.url:: - The URL of a remote repository. See linkgit:git-fetch[1] or - linkgit:git-push[1]. - -remote.<name>.pushurl:: - The push URL of a remote repository. See linkgit:git-push[1]. - -remote.<name>.proxy:: - For remotes that require curl (http, https and ftp), the URL to - the proxy to use for that remote. Set to the empty string to - disable proxying for that remote. - -remote.<name>.proxyAuthMethod:: - For remotes that require curl (http, https and ftp), the method to use for - authenticating against the proxy in use (probably set in - `remote.<name>.proxy`). See `http.proxyAuthMethod`. - -remote.<name>.fetch:: - The default set of "refspec" for linkgit:git-fetch[1]. See - linkgit:git-fetch[1]. - -remote.<name>.push:: - The default set of "refspec" for linkgit:git-push[1]. See - linkgit:git-push[1]. - -remote.<name>.mirror:: - If true, pushing to this remote will automatically behave - as if the `--mirror` option was given on the command line. - -remote.<name>.skipDefaultUpdate:: - If true, this remote will be skipped by default when updating - using linkgit:git-fetch[1] or the `update` subcommand of - linkgit:git-remote[1]. - -remote.<name>.skipFetchAll:: - If true, this remote will be skipped by default when updating - using linkgit:git-fetch[1] or the `update` subcommand of - linkgit:git-remote[1]. - -remote.<name>.receivepack:: - The default program to execute on the remote side when pushing. See - option --receive-pack of linkgit:git-push[1]. - -remote.<name>.uploadpack:: - The default program to execute on the remote side when fetching. See - option --upload-pack of linkgit:git-fetch-pack[1]. - -remote.<name>.tagOpt:: - Setting this value to --no-tags disables automatic tag following when - fetching from remote <name>. Setting it to --tags will fetch every - tag from remote <name>, even if they are not reachable from remote - branch heads. Passing these flags directly to linkgit:git-fetch[1] can - override this setting. See options --tags and --no-tags of - linkgit:git-fetch[1]. - -remote.<name>.vcs:: - Setting this to a value <vcs> will cause Git to interact with - the remote with the git-remote-<vcs> helper. - -remote.<name>.prune:: - When set to true, fetching from this remote by default will also - remove any remote-tracking references that no longer exist on the - remote (as if the `--prune` option was given on the command line). - Overrides `fetch.prune` settings, if any. - -remote.<name>.pruneTags:: - When set to true, fetching from this remote by default will also - remove any local tags that no longer exist on the remote if pruning - is activated in general via `remote.<name>.prune`, `fetch.prune` or - `--prune`. Overrides `fetch.pruneTags` settings, if any. -+ -See also `remote.<name>.prune` and the PRUNING section of -linkgit:git-fetch[1]. - -remotes.<group>:: - The list of remotes which are fetched by "git remote update - <group>". See linkgit:git-remote[1]. - -repack.useDeltaBaseOffset:: - By default, linkgit:git-repack[1] creates packs that use - delta-base offset. If you need to share your repository with - Git older than version 1.4.4, either directly or via a dumb - protocol such as http, then you need to set this option to - "false" and repack. Access from old Git versions over the - native protocol are unaffected by this option. - -repack.packKeptObjects:: - If set to true, makes `git repack` act as if - `--pack-kept-objects` was passed. See linkgit:git-repack[1] for - details. Defaults to `false` normally, but `true` if a bitmap - index is being written (either via `--write-bitmap-index` or - `repack.writeBitmaps`). - -repack.useDeltaIslands:: - If set to true, makes `git repack` act as if `--delta-islands` - was passed. Defaults to `false`. - -repack.writeBitmaps:: - When true, git will write a bitmap index when packing all - objects to disk (e.g., when `git repack -a` is run). This - index can speed up the "counting objects" phase of subsequent - packs created for clones and fetches, at the cost of some disk - space and extra time spent on the initial repack. This has - no effect if multiple packfiles are created. - Defaults to false. - -rerere.autoUpdate:: - When set to true, `git-rerere` updates the index with the - resulting contents after it cleanly resolves conflicts using - previously recorded resolution. Defaults to false. - -rerere.enabled:: - Activate recording of resolved conflicts, so that identical - conflict hunks can be resolved automatically, should they be - encountered again. By default, linkgit:git-rerere[1] is - enabled if there is an `rr-cache` directory under the - `$GIT_DIR`, e.g. if "rerere" was previously used in the - repository. - -sendemail.identity:: - A configuration identity. When given, causes values in the - 'sendemail.<identity>' subsection to take precedence over - values in the 'sendemail' section. The default identity is - the value of `sendemail.identity`. - -sendemail.smtpEncryption:: - See linkgit:git-send-email[1] for description. Note that this - setting is not subject to the 'identity' mechanism. - -sendemail.smtpssl (deprecated):: - Deprecated alias for 'sendemail.smtpEncryption = ssl'. - -sendemail.smtpsslcertpath:: - Path to ca-certificates (either a directory or a single file). - Set it to an empty string to disable certificate verification. - -sendemail.<identity>.*:: - Identity-specific versions of the 'sendemail.*' parameters - found below, taking precedence over those when this - identity is selected, through either the command-line or - `sendemail.identity`. - -sendemail.aliasesFile:: -sendemail.aliasFileType:: -sendemail.annotate:: -sendemail.bcc:: -sendemail.cc:: -sendemail.ccCmd:: -sendemail.chainReplyTo:: -sendemail.confirm:: -sendemail.envelopeSender:: -sendemail.from:: -sendemail.multiEdit:: -sendemail.signedoffbycc:: -sendemail.smtpPass:: -sendemail.suppresscc:: -sendemail.suppressFrom:: -sendemail.to:: -sendemail.tocmd:: -sendemail.smtpDomain:: -sendemail.smtpServer:: -sendemail.smtpServerPort:: -sendemail.smtpServerOption:: -sendemail.smtpUser:: -sendemail.thread:: -sendemail.transferEncoding:: -sendemail.validate:: -sendemail.xmailer:: - See linkgit:git-send-email[1] for description. - -sendemail.signedoffcc (deprecated):: - Deprecated alias for `sendemail.signedoffbycc`. - -sendemail.smtpBatchSize:: - Number of messages to be sent per connection, after that a relogin - will happen. If the value is 0 or undefined, send all messages in - one connection. - See also the `--batch-size` option of linkgit:git-send-email[1]. - -sendemail.smtpReloginDelay:: - Seconds wait before reconnecting to smtp server. - See also the `--relogin-delay` option of linkgit:git-send-email[1]. - -showbranch.default:: - The default set of branches for linkgit:git-show-branch[1]. - See linkgit:git-show-branch[1]. - -splitIndex.maxPercentChange:: - When the split index feature is used, this specifies the - percent of entries the split index can contain compared to the - total number of entries in both the split index and the shared - index before a new shared index is written. - The value should be between 0 and 100. If the value is 0 then - a new shared index is always written, if it is 100 a new - shared index is never written. - By default the value is 20, so a new shared index is written - if the number of entries in the split index would be greater - than 20 percent of the total number of entries. - See linkgit:git-update-index[1]. - -splitIndex.sharedIndexExpire:: - When the split index feature is used, shared index files that - were not modified since the time this variable specifies will - be removed when a new shared index file is created. The value - "now" expires all entries immediately, and "never" suppresses - expiration altogether. - The default value is "2.weeks.ago". - Note that a shared index file is considered modified (for the - purpose of expiration) each time a new split-index file is - either created based on it or read from it. - See linkgit:git-update-index[1]. - -status.relativePaths:: - By default, linkgit:git-status[1] shows paths relative to the - current directory. Setting this variable to `false` shows paths - relative to the repository root (this was the default for Git - prior to v1.5.4). - -status.short:: - Set to true to enable --short by default in linkgit:git-status[1]. - The option --no-short takes precedence over this variable. - -status.branch:: - Set to true to enable --branch by default in linkgit:git-status[1]. - The option --no-branch takes precedence over this variable. - -status.displayCommentPrefix:: - If set to true, linkgit:git-status[1] will insert a comment - prefix before each output line (starting with - `core.commentChar`, i.e. `#` by default). This was the - behavior of linkgit:git-status[1] in Git 1.8.4 and previous. - Defaults to false. - -status.renameLimit:: - The number of files to consider when performing rename detection - in linkgit:git-status[1] and linkgit:git-commit[1]. Defaults to - the value of diff.renameLimit. - -status.renames:: - Whether and how Git detects renames in linkgit:git-status[1] and - linkgit:git-commit[1] . If set to "false", rename detection is - disabled. If set to "true", basic rename detection is enabled. - If set to "copies" or "copy", Git will detect copies, as well. - Defaults to the value of diff.renames. - -status.showStash:: - If set to true, linkgit:git-status[1] will display the number of - entries currently stashed away. - Defaults to false. - -status.showUntrackedFiles:: - By default, linkgit:git-status[1] and linkgit:git-commit[1] show - files which are not currently tracked by Git. Directories which - contain only untracked files, are shown with the directory name - only. Showing untracked files means that Git needs to lstat() all - the files in the whole repository, which might be slow on some - systems. So, this variable controls how the commands displays - the untracked files. Possible values are: -+ --- -* `no` - Show no untracked files. -* `normal` - Show untracked files and directories. -* `all` - Show also individual files in untracked directories. --- -+ -If this variable is not specified, it defaults to 'normal'. -This variable can be overridden with the -u|--untracked-files option -of linkgit:git-status[1] and linkgit:git-commit[1]. - -status.submoduleSummary:: - Defaults to false. - If this is set to a non zero number or true (identical to -1 or an - unlimited number), the submodule summary will be enabled and a - summary of commits for modified submodules will be shown (see - --summary-limit option of linkgit:git-submodule[1]). Please note - that the summary output command will be suppressed for all - submodules when `diff.ignoreSubmodules` is set to 'all' or only - for those submodules where `submodule.<name>.ignore=all`. The only - exception to that rule is that status and commit will show staged - submodule changes. To - also view the summary for ignored submodules you can either use - the --ignore-submodules=dirty command-line option or the 'git - submodule summary' command, which shows a similar output but does - not honor these settings. - -stash.showPatch:: - If this is set to true, the `git stash show` command without an - option will show the stash entry in patch form. Defaults to false. - See description of 'show' command in linkgit:git-stash[1]. - -stash.showStat:: - If this is set to true, the `git stash show` command without an - option will show diffstat of the stash entry. Defaults to true. - See description of 'show' command in linkgit:git-stash[1]. - -submodule.<name>.url:: - The URL for a submodule. This variable is copied from the .gitmodules - file to the git config via 'git submodule init'. The user can change - the configured URL before obtaining the submodule via 'git submodule - update'. If neither submodule.<name>.active or submodule.active are - set, the presence of this variable is used as a fallback to indicate - whether the submodule is of interest to git commands. - See linkgit:git-submodule[1] and linkgit:gitmodules[5] for details. - -submodule.<name>.update:: - The method by which a submodule is updated by 'git submodule update', - which is the only affected command, others such as - 'git checkout --recurse-submodules' are unaffected. It exists for - historical reasons, when 'git submodule' was the only command to - interact with submodules; settings like `submodule.active` - and `pull.rebase` are more specific. It is populated by - `git submodule init` from the linkgit:gitmodules[5] file. - See description of 'update' command in linkgit:git-submodule[1]. - -submodule.<name>.branch:: - The remote branch name for a submodule, used by `git submodule - update --remote`. Set this option to override the value found in - the `.gitmodules` file. See linkgit:git-submodule[1] and - linkgit:gitmodules[5] for details. - -submodule.<name>.fetchRecurseSubmodules:: - This option can be used to control recursive fetching of this - submodule. It can be overridden by using the --[no-]recurse-submodules - command-line option to "git fetch" and "git pull". - This setting will override that from in the linkgit:gitmodules[5] - file. - -submodule.<name>.ignore:: - Defines under what circumstances "git status" and the diff family show - a submodule as modified. When set to "all", it will never be considered - modified (but it will nonetheless show up in the output of status and - commit when it has been staged), "dirty" will ignore all changes - to the submodules work tree and - takes only differences between the HEAD of the submodule and the commit - recorded in the superproject into account. "untracked" will additionally - let submodules with modified tracked files in their work tree show up. - Using "none" (the default when this option is not set) also shows - submodules that have untracked files in their work tree as changed. - This setting overrides any setting made in .gitmodules for this submodule, - both settings can be overridden on the command line by using the - "--ignore-submodules" option. The 'git submodule' commands are not - affected by this setting. - -submodule.<name>.active:: - Boolean value indicating if the submodule is of interest to git - commands. This config option takes precedence over the - submodule.active config option. See linkgit:gitsubmodules[7] for - details. - -submodule.active:: - A repeated field which contains a pathspec used to match against a - submodule's path to determine if the submodule is of interest to git - commands. See linkgit:gitsubmodules[7] for details. - -submodule.recurse:: - Specifies if commands recurse into submodules by default. This - applies to all commands that have a `--recurse-submodules` option, - except `clone`. - Defaults to false. - -submodule.fetchJobs:: - Specifies how many submodules are fetched/cloned at the same time. - A positive integer allows up to that number of submodules fetched - in parallel. A value of 0 will give some reasonable default. - If unset, it defaults to 1. - -submodule.alternateLocation:: - Specifies how the submodules obtain alternates when submodules are - cloned. Possible values are `no`, `superproject`. - By default `no` is assumed, which doesn't add references. When the - value is set to `superproject` the submodule to be cloned computes - its alternates location relative to the superprojects alternate. - -submodule.alternateErrorStrategy:: - Specifies how to treat errors with the alternates for a submodule - as computed via `submodule.alternateLocation`. Possible values are - `ignore`, `info`, `die`. Default is `die`. - -tag.forceSignAnnotated:: - A boolean to specify whether annotated tags created should be GPG signed. - If `--annotate` is specified on the command line, it takes - precedence over this option. - -tag.sort:: - This variable controls the sort ordering of tags when displayed by - linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the - value of this variable will be used as the default. - -tar.umask:: - This variable can be used to restrict the permission bits of - tar archive entries. The default is 0002, which turns off the - world write bit. The special value "user" indicates that the - archiving user's umask will be used instead. See umask(2) and - linkgit:git-archive[1]. - -transfer.fsckObjects:: - When `fetch.fsckObjects` or `receive.fsckObjects` are - not set, the value of this variable is used instead. - Defaults to false. -+ -When set, the fetch or receive will abort in the case of a malformed -object or a link to a nonexistent object. In addition, various other -issues are checked for, including legacy issues (see `fsck.<msg-id>`), -and potential security issues like the existence of a `.GIT` directory -or a malicious `.gitmodules` file (see the release notes for v2.2.1 -and v2.17.1 for details). Other sanity and security checks may be -added in future releases. -+ -On the receiving side, failing fsckObjects will make those objects -unreachable, see "QUARANTINE ENVIRONMENT" in -linkgit:git-receive-pack[1]. On the fetch side, malformed objects will -instead be left unreferenced in the repository. -+ -Due to the non-quarantine nature of the `fetch.fsckObjects` -implementation it can not be relied upon to leave the object store -clean like `receive.fsckObjects` can. -+ -As objects are unpacked they're written to the object store, so there -can be cases where malicious objects get introduced even though the -"fetch" failed, only to have a subsequent "fetch" succeed because only -new incoming objects are checked, not those that have already been -written to the object store. That difference in behavior should not be -relied upon. In the future, such objects may be quarantined for -"fetch" as well. -+ -For now, the paranoid need to find some way to emulate the quarantine -environment if they'd like the same protection as "push". E.g. in the -case of an internal mirror do the mirroring in two steps, one to fetch -the untrusted objects, and then do a second "push" (which will use the -quarantine) to another internal repo, and have internal clients -consume this pushed-to repository, or embargo internal fetches and -only allow them once a full "fsck" has run (and no new fetches have -happened in the meantime). - -transfer.hideRefs:: - String(s) `receive-pack` and `upload-pack` use to decide which - refs to omit from their initial advertisements. Use more than - one definition to specify multiple prefix strings. A ref that is - under the hierarchies listed in the value of this variable is - excluded, and is hidden when responding to `git push` or `git - fetch`. See `receive.hideRefs` and `uploadpack.hideRefs` for - program-specific versions of this config. -+ -You may also include a `!` in front of the ref name to negate the entry, -explicitly exposing it, even if an earlier entry marked it as hidden. -If you have multiple hideRefs values, later entries override earlier ones -(and entries in more-specific config files override less-specific ones). -+ -If a namespace is in use, the namespace prefix is stripped from each -reference before it is matched against `transfer.hiderefs` patterns. -For example, if `refs/heads/master` is specified in `transfer.hideRefs` and -the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master` -is omitted from the advertisements but `refs/heads/master` and -`refs/namespaces/bar/refs/heads/master` are still advertised as so-called -"have" lines. In order to match refs before stripping, add a `^` in front of -the ref name. If you combine `!` and `^`, `!` must be specified first. -+ -Even if you hide refs, a client may still be able to steal the target -objects via the techniques described in the "SECURITY" section of the -linkgit:gitnamespaces[7] man page; it's best to keep private data in a -separate repository. - -transfer.unpackLimit:: - When `fetch.unpackLimit` or `receive.unpackLimit` are - not set, the value of this variable is used instead. - The default value is 100. - -uploadarchive.allowUnreachable:: - If true, allow clients to use `git archive --remote` to request - any tree, whether reachable from the ref tips or not. See the - discussion in the "SECURITY" section of - linkgit:git-upload-archive[1] for more details. Defaults to - `false`. - -uploadpack.hideRefs:: - This variable is the same as `transfer.hideRefs`, but applies - only to `upload-pack` (and so affects only fetches, not pushes). - An attempt to fetch a hidden ref by `git fetch` will fail. See - also `uploadpack.allowTipSHA1InWant`. - -uploadpack.allowTipSHA1InWant:: - When `uploadpack.hideRefs` is in effect, allow `upload-pack` - to accept a fetch request that asks for an object at the tip - of a hidden ref (by default, such a request is rejected). - See also `uploadpack.hideRefs`. Even if this is false, a client - may be able to steal objects via the techniques described in the - "SECURITY" section of the linkgit:gitnamespaces[7] man page; it's - best to keep private data in a separate repository. - -uploadpack.allowReachableSHA1InWant:: - Allow `upload-pack` to accept a fetch request that asks for an - object that is reachable from any ref tip. However, note that - calculating object reachability is computationally expensive. - Defaults to `false`. Even if this is false, a client may be able - to steal objects via the techniques described in the "SECURITY" - section of the linkgit:gitnamespaces[7] man page; it's best to - keep private data in a separate repository. - -uploadpack.allowAnySHA1InWant:: - Allow `upload-pack` to accept a fetch request that asks for any - object at all. - Defaults to `false`. - -uploadpack.keepAlive:: - When `upload-pack` has started `pack-objects`, there may be a - quiet period while `pack-objects` prepares the pack. Normally - it would output progress information, but if `--quiet` was used - for the fetch, `pack-objects` will output nothing at all until - the pack data begins. Some clients and networks may consider - the server to be hung and give up. Setting this option instructs - `upload-pack` to send an empty keepalive packet every - `uploadpack.keepAlive` seconds. Setting this option to 0 - disables keepalive packets entirely. The default is 5 seconds. - -uploadpack.packObjectsHook:: - If this option is set, when `upload-pack` would run - `git pack-objects` to create a packfile for a client, it will - run this shell command instead. The `pack-objects` command and - arguments it _would_ have run (including the `git pack-objects` - at the beginning) are appended to the shell command. The stdin - and stdout of the hook are treated as if `pack-objects` itself - was run. I.e., `upload-pack` will feed input intended for - `pack-objects` to the hook, and expects a completed packfile on - stdout. - -uploadpack.allowFilter:: - If this option is set, `upload-pack` will support partial - clone and partial fetch object filtering. -+ -Note that this configuration variable is ignored if it is seen in the -repository-level config (this is a safety measure against fetching from -untrusted repositories). - -uploadpack.allowRefInWant:: - If this option is set, `upload-pack` will support the `ref-in-want` - feature of the protocol version 2 `fetch` command. This feature - is intended for the benefit of load-balanced servers which may - not have the same view of what OIDs their refs point to due to - replication delay. - -url.<base>.insteadOf:: - Any URL that starts with this value will be rewritten to - start, instead, with <base>. In cases where some site serves a - large number of repositories, and serves them with multiple - access methods, and some users need to use different access - methods, this feature allows people to specify any of the - equivalent URLs and have Git automatically rewrite the URL to - the best alternative for the particular user, even for a - never-before-seen repository on the site. When more than one - insteadOf strings match a given URL, the longest match is used. -+ -Note that any protocol restrictions will be applied to the rewritten -URL. If the rewrite changes the URL to use a custom protocol or remote -helper, you may need to adjust the `protocol.*.allow` config to permit -the request. In particular, protocols you expect to use for submodules -must be set to `always` rather than the default of `user`. See the -description of `protocol.allow` above. - -url.<base>.pushInsteadOf:: - Any URL that starts with this value will not be pushed to; - instead, it will be rewritten to start with <base>, and the - resulting URL will be pushed to. In cases where some site serves - a large number of repositories, and serves them with multiple - access methods, some of which do not allow push, this feature - allows people to specify a pull-only URL and have Git - automatically use an appropriate URL to push, even for a - never-before-seen repository on the site. When more than one - pushInsteadOf strings match a given URL, the longest match is - used. If a remote has an explicit pushurl, Git will ignore this - setting for that remote. - -user.email:: - Your email address to be recorded in any newly created commits. - Can be overridden by the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL`, and - `EMAIL` environment variables. See linkgit:git-commit-tree[1]. - -user.name:: - Your full name to be recorded in any newly created commits. - Can be overridden by the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME` - environment variables. See linkgit:git-commit-tree[1]. - -user.useConfigOnly:: - Instruct Git to avoid trying to guess defaults for `user.email` - and `user.name`, and instead retrieve the values only from the - configuration. For example, if you have multiple email addresses - and would like to use a different one for each repository, then - with this configuration option set to `true` in the global config - along with a name, Git will prompt you to set up an email before - making new commits in a newly cloned repository. - Defaults to `false`. - -user.signingKey:: - If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the - key you want it to automatically when creating a signed tag or - commit, you can override the default selection with this variable. - This option is passed unchanged to gpg's --local-user parameter, - so you may specify a key using any method that gpg supports. - -versionsort.prereleaseSuffix (deprecated):: - Deprecated alias for `versionsort.suffix`. Ignored if - `versionsort.suffix` is set. - -versionsort.suffix:: - Even when version sort is used in linkgit:git-tag[1], tagnames - with the same base version but different suffixes are still sorted - lexicographically, resulting e.g. in prerelease tags appearing - after the main release (e.g. "1.0-rc1" after "1.0"). This - variable can be specified to determine the sorting order of tags - with different suffixes. -+ -By specifying a single suffix in this variable, any tagname containing -that suffix will appear before the corresponding main release. E.g. if -the variable is set to "-rc", then all "1.0-rcX" tags will appear before -"1.0". If specified multiple times, once per suffix, then the order of -suffixes in the configuration will determine the sorting order of tagnames -with those suffixes. E.g. if "-pre" appears before "-rc" in the -configuration, then all "1.0-preX" tags will be listed before any -"1.0-rcX" tags. The placement of the main release tag relative to tags -with various suffixes can be determined by specifying the empty suffix -among those other suffixes. E.g. if the suffixes "-rc", "", "-ck" and -"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags -are listed first, followed by "v4.8", then "v4.8-ckX" and finally -"v4.8-bfsX". -+ -If more than one suffixes match the same tagname, then that tagname will -be sorted according to the suffix which starts at the earliest position in -the tagname. If more than one different matching suffixes start at -that earliest position, then that tagname will be sorted according to the -longest of those suffixes. -The sorting order between different suffixes is undefined if they are -in multiple config files. - -web.browser:: - Specify a web browser that may be used by some commands. - Currently only linkgit:git-instaweb[1] and linkgit:git-help[1] - may use it. - -worktree.guessRemote:: - With `add`, if no branch argument, and neither of `-b` nor - `-B` nor `--detach` are given, the command defaults to - creating a new branch from HEAD.

Before + setting it to `true`, you should check that mtime is working + properly on your system. + See linkgit:git-update-index[1]. `keep` by default. + +core.checkStat:: + When missing or is set to `default`, many fields in the stat + structure are checked to detect if a file has been modified + since Git looked at it. When this configuration variable is + set to `minimal`, sub-second part of mtime and ctime, the + uid and gid of the owner of the file, the inode number (and + the device number, if Git was compiled to use it), are + excluded from the check among these fields, leaving only the + whole-second part of mtime (and ctime, if `core.trustCtime` + is set) and the filesize to be checked. ++ +There are implementations of Git that do not leave usable values in +some fields (e.g. JGit); by excluding these fields from the +comparison, the `minimal` mode may help interoperability when the +same repository is used by these other systems at the same time. + +core.quotePath:: + Commands that output paths (e.g. 'ls-files', 'diff'), will + quote "unusual" characters in the pathname by enclosing the + pathname in double-quotes and escaping those characters with + backslashes in the same way C escapes control characters (e.g. + `\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with + values larger than 0x80 (e.g. octal `\302\265` for "micro" in + UTF-8). If this variable is set to false, bytes higher than + 0x80 are not considered "unusual" any more. Double-quotes, + backslash and control characters are always escaped regardless + of the setting of this variable. A simple space character is + not considered "unusual". Many commands can output pathnames + completely verbatim using the `-z` option. The default value + is true. + +core.eol:: + Sets the line ending type to use in the working directory for + files that have the `text` property set when core.autocrlf is false. + Alternatives are 'lf', 'crlf' and 'native', which uses the platform's + native line ending. The default value is `native`. See + linkgit:gitattributes[5] for more information on end-of-line + conversion. + +core.safecrlf:: + If true, makes Git check if converting `CRLF` is reversible when + end-of-line conversion is active. Git will verify if a command + modifies a file in the work tree either directly or indirectly. + For example, committing a file followed by checking out the + same file should yield the original file in the work tree. If + this is not the case for the current setting of + `core.autocrlf`, Git will reject the file. The variable can + be set to "warn", in which case Git will only warn about an + irreversible conversion but continue the operation. ++ +CRLF conversion bears a slight chance of corrupting data. +When it is enabled, Git will convert CRLF to LF during commit and LF to +CRLF during checkout. A file that contains a mixture of LF and +CRLF before the commit cannot be recreated by Git. For text +files this is the right thing to do: it corrects line endings +such that we have only LF line endings in the repository. +But for binary files that are accidentally classified as text the +conversion can corrupt data. ++ +If you recognize such corruption early you can easily fix it by +setting the conversion type explicitly in .gitattributes. Right +after committing you still have the original file in your work +tree and this file is not yet corrupted. You can explicitly tell +Git that this file is binary and Git will handle the file +appropriately. ++ +Unfortunately, the desired effect of cleaning up text files with +mixed line endings and the undesired effect of corrupting binary +files cannot be distinguished. In both cases CRLFs are removed +in an irreversible way. For text files this is the right thing +to do because CRLFs are line endings, while for binary files +converting CRLFs corrupts data. ++ +Note, this safety check does not mean that a checkout will generate a +file identical to the original file for a different setting of +`core.eol` and `core.autocrlf`, but only for the current one. For +example, a text file with `LF` would be accepted with `core.eol=lf` +and could later be checked out with `core.eol=crlf`, in which case the +resulting file would contain `CRLF`, although the original file +contained `LF`. However, in both work trees the line endings would be +consistent, that is either all `LF` or all `CRLF`, but never mixed. A +file with mixed line endings would be reported by the `core.safecrlf` +mechanism. + +core.autocrlf:: + Setting this variable to "true" is the same as setting + the `text` attribute to "auto" on all files and core.eol to "crlf". + Set to true if you want to have `CRLF` line endings in your + working directory and the repository has LF line endings. + This variable can be set to 'input', + in which case no output conversion is performed. + +core.checkRoundtripEncoding:: + A comma and/or whitespace separated list of encodings that Git + performs UTF-8 round trip checks on if they are used in an + `working-tree-encoding` attribute (see linkgit:gitattributes[5]). + The default value is `SHIFT-JIS`. + +core.symlinks:: + If false, symbolic links are checked out as small plain files that + contain the link text. linkgit:git-update-index[1] and + linkgit:git-add[1] will not change the recorded type to regular + file. Useful on filesystems like FAT that do not support + symbolic links. ++ +The default is true, except linkgit:git-clone[1] or linkgit:git-init[1] +will probe and set core.symlinks false if appropriate when the repository +is created. + +core.gitProxy:: + A "proxy command" to execute (as 'command host port') instead + of establishing direct connection to the remote server when + using the Git protocol for fetching. If the variable value is + in the "COMMAND for DOMAIN" format, the command is applied only + on hostnames ending with the specified domain string. This variable + may be set multiple times and is matched in the given order; + the first match wins. ++ +Can be overridden by the `GIT_PROXY_COMMAND` environment variable +(which always applies universally, without the special "for" +handling). ++ +The special string `none` can be used as the proxy command to +specify that no proxy be used for a given domain pattern. +This is useful for excluding servers inside a firewall from +proxy use, while defaulting to a common proxy for external domains. + +core.sshCommand:: + If this variable is set, `git fetch` and `git push` will + use the specified command instead of `ssh` when they need to + connect to a remote system. The command is in the same form as + the `GIT_SSH_COMMAND` environment variable and is overridden + when the environment variable is set. + +core.ignoreStat:: + If true, Git will avoid using lstat() calls to detect if files have + changed by setting the "assume-unchanged" bit for those tracked files + which it has updated identically in both the index and working tree. ++ +When files are modified outside of Git, the user will need to stage +the modified files explicitly (e.g. see 'Examples' section in +linkgit:git-update-index[1]). +Git will not normally detect changes to those files. ++ +This is useful on systems where lstat() calls are very slow, such as +CIFS/Microsoft Windows. ++ +False by default. + +core.preferSymlinkRefs:: + Instead of the default "symref" format for HEAD + and other symbolic reference files, use symbolic links. + This is sometimes needed to work with old scripts that + expect HEAD to be a symbolic link. + +core.alternateRefsCommand:: + When advertising tips of available history from an alternate, use the shell to + execute the specified command instead of linkgit:git-for-each-ref[1]. The + first argument is the absolute path of the alternate. Output must contain one + hex object id per line (i.e., the same as produced by `git for-each-ref + --format='%(objectname)'`). ++ +Note that you cannot generally put `git for-each-ref` directly into the config +value, as it does not take a repository path as an argument (but you can wrap +the command above in a shell script). + +core.alternateRefsPrefixes:: + When listing references from an alternate, list only references that begin + with the given prefix. Prefixes match as if they were given as arguments to + linkgit:git-for-each-ref[1]. To list multiple prefixes, separate them with + whitespace. If `core.alternateRefsCommand` is set, setting + `core.alternateRefsPrefixes` has no effect. + +core.bare:: + If true this repository is assumed to be 'bare' and has no + working directory associated with it. If this is the case a + number of commands that require a working directory will be + disabled, such as linkgit:git-add[1] or linkgit:git-merge[1]. ++ +This setting is automatically guessed by linkgit:git-clone[1] or +linkgit:git-init[1] when the repository was created. By default a +repository that ends in "/.git" is assumed to be not bare (bare = +false), while all other repositories are assumed to be bare (bare += true). + +core.worktree:: + Set the path to the root of the working tree. + If `GIT_COMMON_DIR` environment variable is set, core.worktree + is ignored and not used for determining the root of working tree. + This can be overridden by the `GIT_WORK_TREE` environment + variable and the `--work-tree` command-line option. + The value can be an absolute path or relative to the path to + the .git directory, which is either specified by --git-dir + or GIT_DIR, or automatically discovered. + If --git-dir or GIT_DIR is specified but none of + --work-tree, GIT_WORK_TREE and core.worktree is specified, + the current working directory is regarded as the top level + of your working tree. ++ +Note that this variable is honored even when set in a configuration +file in a ".git" subdirectory of a directory and its value differs +from the latter directory (e.g. "/path/to/.git/config" has +core.worktree set to "/different/path"), which is most likely a +misconfiguration. Running Git commands in the "/path/to" directory will +still use "/different/path" as the root of the work tree and can cause +confusion unless you know what you are doing (e.g. you are creating a +read-only snapshot of the same index to a location different from the +repository's usual working tree). + +core.logAllRefUpdates:: + Enable the reflog. Updates to a ref <ref> is logged to the file + "`$GIT_DIR/logs/<ref>`", by appending the new and old + SHA-1, the date/time and the reason of the update, but + only when the file exists. If this configuration + variable is set to `true`, missing "`$GIT_DIR/logs/<ref>`" + file is automatically created for branch heads (i.e. under + `refs/heads/`), remote refs (i.e. under `refs/remotes/`), + note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`. + If it is set to `always`, then a missing reflog is automatically + created for any ref under `refs/`. ++ +This information can be used to determine what commit +was the tip of a branch "2 days ago". ++ +This value is true by default in a repository that has +a working directory associated with it, and false by +default in a bare repository. + +core.repositoryFormatVersion:: + Internal variable identifying the repository format and layout + version. + +core.sharedRepository:: + When 'group' (or 'true'), the repository is made shareable between + several users in a group (making sure all the files and objects are + group-writable). When 'all' (or 'world' or 'everybody'), the + repository will be readable by all users, additionally to being + group-shareable. When 'umask' (or 'false'), Git will use permissions + reported by umask(2). When '0xxx', where '0xxx' is an octal number, + files in the repository will have this mode value. '0xxx' will override + user's umask value (whereas the other options will only override + requested parts of the user's umask value). Examples: '0660' will make + the repo read/write-able for the owner and group, but inaccessible to + others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a + repository that is group-readable but not group-writable. + See linkgit:git-init[1]. False by default. + +core.warnAmbiguousRefs:: + If true, Git will warn you if the ref name you passed it is ambiguous + and might match multiple refs in the repository. True by default. + +core.compression:: + An integer -1..9, indicating a default compression level. + -1 is the zlib default. 0 means no compression, + and 1..9 are various speed/size tradeoffs, 9 being slowest. + If set, this provides a default to other compression variables, + such as `core.looseCompression` and `pack.compression`. + +core.looseCompression:: + An integer -1..9, indicating the compression level for objects that + are not in a pack file. -1 is the zlib default. 0 means no + compression, and 1..9 are various speed/size tradeoffs, 9 being + slowest. If not set, defaults to core.compression. If that is + not set, defaults to 1 (best speed). + +core.packedGitWindowSize:: + Number of bytes of a pack file to map into memory in a + single mapping operation. Larger window sizes may allow + your system to process a smaller number of large pack files + more quickly. Smaller window sizes will negatively affect + performance due to increased calls to the operating system's + memory manager, but may improve performance when accessing + a large number of large pack files. ++ +Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 +MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should +be reasonable for all users/operating systems. You probably do +not need to adjust this value. ++ +Common unit suffixes of 'k', 'm', or 'g' are supported. + +core.packedGitLimit:: + Maximum number of bytes to map simultaneously into memory + from pack files. If Git needs to access more than this many + bytes at once to complete an operation it will unmap existing + regions to reclaim virtual address space within the process. ++ +Default is 256 MiB on 32 bit platforms and 32 TiB (effectively +unlimited) on 64 bit platforms. +This should be reasonable for all users/operating systems, except on +the largest projects. You probably do not need to adjust this value. ++ +Common unit suffixes of 'k', 'm', or 'g' are supported. + +core.deltaBaseCacheLimit:: + Maximum number of bytes to reserve for caching base objects + that may be referenced by multiple deltified objects. By storing the + entire decompressed base objects in a cache Git is able + to avoid unpacking and decompressing frequently used base + objects multiple times. ++ +Default is 96 MiB on all platforms. This should be reasonable +for all users/operating systems, except on the largest projects. +You probably do not need to adjust this value. ++ +Common unit suffixes of 'k', 'm', or 'g' are supported. + +core.bigFileThreshold:: + Files larger than this size are stored deflated, without + attempting delta compression. Storing large files without + delta compression avoids excessive memory usage, at the + slight expense of increased disk usage. Additionally files + larger than this size are always treated as binary. ++ +Default is 512 MiB on all platforms. This should be reasonable +for most projects as source code and other text files can still +be delta compressed, but larger binary media files won't be. ++ +Common unit suffixes of 'k', 'm', or 'g' are supported. + +core.excludesFile:: + Specifies the pathname to the file that contains patterns to + describe paths that are not meant to be tracked, in addition + to '.gitignore' (per-directory) and '.git/info/exclude'. + Defaults to `$XDG_CONFIG_HOME/git/ignore`. + If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore` + is used instead. See linkgit:gitignore[5]. + +core.askPass:: + Some commands (e.g. svn and http interfaces) that interactively + ask for a password can be told to use an external program given + via the value of this variable. Can be overridden by the `GIT_ASKPASS` + environment variable. If not set, fall back to the value of the + `SSH_ASKPASS` environment variable or, failing that, a simple password + prompt. The external program shall be given a suitable prompt as + command-line argument and write the password on its STDOUT. + +core.attributesFile:: + In addition to '.gitattributes' (per-directory) and + '.git/info/attributes', Git looks into this file for attributes + (see linkgit:gitattributes[5]). Path expansions are made the same + way as for `core.excludesFile`. Its default value is + `$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not + set or empty, `$HOME/.config/git/attributes` is used instead. + +core.hooksPath:: + By default Git will look for your hooks in the + '$GIT_DIR/hooks' directory. Set this to different path, + e.g. '/etc/git/hooks', and Git will try to find your hooks in + that directory, e.g. '/etc/git/hooks/pre-receive' instead of + in '$GIT_DIR/hooks/pre-receive'. ++ +The path can be either absolute or relative. A relative path is +taken as relative to the directory where the hooks are run (see +the "DESCRIPTION" section of linkgit:githooks[5]). ++ +This configuration variable is useful in cases where you'd like to +centrally configure your Git hooks instead of configuring them on a +per-repository basis, or as a more flexible and centralized +alternative to having an `init.templateDir` where you've changed +default hooks. + +core.editor:: + Commands such as `commit` and `tag` that let you edit + messages by launching an editor use the value of this + variable when it is set, and the environment variable + `GIT_EDITOR` is not set. See linkgit:git-var[1]. + +core.commentChar:: + Commands such as `commit` and `tag` that let you edit + messages consider a line that begins with this character + commented, and removes them after the editor returns + (default '#'). ++ +If set to "auto", `git-commit` would select a character that is not +the beginning character of any line in existing commit messages. + +core.filesRefLockTimeout:: + The length of time, in milliseconds, to retry when trying to + lock an individual reference. Value 0 means not to retry at + all; -1 means to try indefinitely. Default is 100 (i.e., + retry for 100ms). + +core.packedRefsTimeout:: + The length of time, in milliseconds, to retry when trying to + lock the `packed-refs` file. Value 0 means not to retry at + all; -1 means to try indefinitely. Default is 1000 (i.e., + retry for 1 second). + +core.pager:: + Text viewer for use by Git commands (e.g., 'less'). The value + is meant to be interpreted by the shell. The order of preference + is the `$GIT_PAGER` environment variable, then `core.pager` + configuration, then `$PAGER`, and then the default chosen at + compile time (usually 'less'). ++ +When the `LESS` environment variable is unset, Git sets it to `FRX` +(if `LESS` environment variable is set, Git does not change it at +all). If you want to selectively override Git's default setting +for `LESS`, you can set `core.pager` to e.g. `less -S`. This will +be passed to the shell by Git, which will translate the final +command to `LESS=FRX less -S`. The environment does not set the +`S` option but the command line does, instructing less to truncate +long lines. Similarly, setting `core.pager` to `less -+F` will +deactivate the `F` option specified by the environment from the +command-line, deactivating the "quit if one screen" behavior of +`less`. One can specifically activate some flags for particular +commands: for example, setting `pager.blame` to `less -S` enables +line truncation only for `git blame`. ++ +Likewise, when the `LV` environment variable is unset, Git sets it +to `-c`. You can override this setting by exporting `LV` with +another value or setting `core.pager` to `lv +c`. + +core.whitespace:: + A comma separated list of common whitespace problems to + notice. 'git diff' will use `color.diff.whitespace` to + highlight them, and 'git apply --whitespace=error' will + consider them as errors. You can prefix `-` to disable + any of them (e.g. `-trailing-space`): ++ +* `blank-at-eol` treats trailing whitespaces at the end of the line + as an error (enabled by default). +* `space-before-tab` treats a space character that appears immediately + before a tab character in the initial indent part of the line as an + error (enabled by default). +* `indent-with-non-tab` treats a line that is indented with space + characters instead of the equivalent tabs as an error (not enabled by + default). +* `tab-in-indent` treats a tab character in the initial indent part of + the line as an error (not enabled by default). +* `blank-at-eof` treats blank lines added at the end of file as an error + (enabled by default). +* `trailing-space` is a short-hand to cover both `blank-at-eol` and + `blank-at-eof`. +* `cr-at-eol` treats a carriage-return at the end of line as + part of the line terminator, i.e. with it, `trailing-space` + does not trigger if the character before such a carriage-return + is not a whitespace (not enabled by default). +* `tabwidth=<n>` tells how many character positions a tab occupies; this + is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent` + errors. The default tab width is 8. Allowed values are 1 to 63. + +core.fsyncObjectFiles:: + This boolean will enable 'fsync()' when writing object files. ++ +This is a total waste of time and effort on a filesystem that orders +data writes properly, but can be useful for filesystems that do not use +journalling (traditional UNIX filesystems) or that only journal metadata +and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback"). + +core.preloadIndex:: + Enable parallel index preload for operations like 'git diff' ++ +This can speed up operations like 'git diff' and 'git status' especially +on filesystems like NFS that have weak caching semantics and thus +relatively high IO latencies. When enabled, Git will do the +index comparison to the filesystem data in parallel, allowing +overlapping IO's. Defaults to true. + +core.unsetenvvars:: + Windows-only: comma-separated list of environment variables' + names that need to be unset before spawning any other process. + Defaults to `PERL5LIB` to account for the fact that Git for + Windows insists on using its own Perl interpreter. + +core.createObject:: + You can set this to 'link', in which case a hardlink followed by + a delete of the source are used to make sure that object creation + will not overwrite existing objects. ++ +On some file system/operating system combinations, this is unreliable. +Set this config setting to 'rename' there; However, This will remove the +check that makes sure that existing object files will not get overwritten. + +core.notesRef:: + When showing commit messages, also show notes which are stored in + the given ref. The ref must be fully qualified. If the given + ref does not exist, it is not an error but means that no + notes should be printed. ++ +This setting defaults to "refs/notes/commits", and it can be overridden by +the `GIT_NOTES_REF` environment variable. See linkgit:git-notes[1]. + +core.commitGraph:: + If true, then git will read the commit-graph file (if it exists) + to parse the graph structure of commits. Defaults to false. See + linkgit:git-commit-graph[1] for more information. + +core.useReplaceRefs:: + If set to `false`, behave as if the `--no-replace-objects` + option was given on the command line. See linkgit:git[1] and + linkgit:git-replace[1] for more information. + +core.multiPackIndex:: + Use the multi-pack-index file to track multiple packfiles using a + single index. See link:technical/multi-pack-index.html[the + multi-pack-index design document]. + +core.sparseCheckout:: + Enable "sparse checkout" feature. See section "Sparse checkout" in + linkgit:git-read-tree[1] for more information. + +core.abbrev:: + Set the length object names are abbreviated to. If + unspecified or set to "auto", an appropriate value is + computed based on the approximate number of packed objects + in your repository, which hopefully is enough for + abbreviated object names to stay unique for some time. + The minimum length is 4. diff --git a/Documentation/config/credential.txt b/Documentation/config/credential.txt new file mode 100644 index 0000000..60fb318 --- /dev/null +++ b/Documentation/config/credential.txt @@ -0,0 +1,26 @@ +credential.helper:: + Specify an external helper to be called when a username or + password credential is needed; the helper may consult external + storage to avoid prompting the user for the credentials.

If set to `initial`, git will follow redirects only for + the initial request to a remote, but not for subsequent + follow-up HTTP requests. Since git uses the redirected URL as + the base for the follow-up requests, this is generally + sufficient. The default is `initial`. + +http.<url>.*:: + Any of the http.* options above can be applied selectively to some URLs. + For a config key to match a URL, each element of the config key is + compared to that of the URL, in the following order: ++ +-- +. Scheme (e.g., `https` in `https://example.com/`). This field + must match exactly between the config key and the URL. + +. Host/domain name (e.g., `example.com` in `https://example.com/`). + This field must match between the config key and the URL. It is + possible to specify a `*` as part of the host name to match all subdomains + at this level. `https://*.example.com/` for example would match + `https://foo.example.com/`, but not `https://foo.bar.example.com/`. + +. Port number (e.g., `8080` in `http://example.com:8080/`). + This field must match exactly between the config key and the URL. + Omitted port numbers are automatically converted to the correct + default for the scheme before matching. + +. Path (e.g., `repo.git` in `https://example.com/repo.git`). The + path field of the config key must match the path field of the URL + either exactly or as a prefix of slash-delimited path elements. This means + a config key with path `foo/` matches URL path `foo/bar`. A prefix can only + match on a slash (`/`) boundary. Longer matches take precedence (so a config + key with path `foo/bar` is a better match to URL path `foo/bar` than a config + key with just path `foo/`). + +. User name (e.g., `user` in `https://user@example.com/repo.git`). If + the config key has a user name it must match the user name in the + URL exactly. If the config key does not have a user name, that + config key will match a URL with any user name (including none), + but at a lower precedence than a config key with a user name. +-- ++ +The list above is ordered by decreasing precedence; a URL that matches +a config key's path is preferred to one that matches its user name. For example, +if the URL is `https://user@example.com/foo/bar` a config key match of +`https://example.com/foo` will be preferred over a config key match of +`https://user@example.com`. ++ +All URLs are normalized before attempting any matching (the password part, +if embedded in the URL, is always ignored for matching purposes) so that +equivalent URLs that are simply spelled differently will match properly. +Environment variable settings always override any matches. The URLs that are +matched against are those given directly to Git commands. This means any URLs +visited as a result of a redirection do not participate in matching. diff --git a/Documentation/config/i18n.txt b/Documentation/config/i18n.txt new file mode 100644 index 0000000..cc25621 --- /dev/null +++ b/Documentation/config/i18n.txt @@ -0,0 +1,10 @@ +i18n.commitEncoding:: + Character encoding the commit messages are stored in; Git itself + does not care per se, but this information is necessary e.g. when + importing commits from emails or in the gitk graphical history + browser (and possibly at other places in the future or in other + porcelains).

When left unconfigured (or + set explicitly to 0), there will be no limit. + +pack.compression:: + An integer -1..9, indicating the compression level for objects + in a pack file. -1 is the zlib default. 0 means no + compression, and 1..9 are various speed/size tradeoffs, 9 being + slowest. If not set, defaults to core.compression. If that is + not set, defaults to -1, the zlib default, which is "a default + compromise between speed and compression (currently equivalent + to level 6)." ++ +Note that changing the compression level will not automatically recompress +all existing objects. You can force recompression by passing the -F option +to linkgit:git-repack[1]. + +pack.island:: + An extended regular expression configuring a set of delta + islands. See "DELTA ISLANDS" in linkgit:git-pack-objects[1] + for details. + +pack.islandCore:: + Specify an island name which gets to have its objects be + packed first. This creates a kind of pseudo-pack at the front + of one pack, so that the objects from the specified island are + hopefully faster to copy into any pack that should be served + to a user requesting these objects. In practice this means + that the island specified should likely correspond to what is + the most commonly cloned in the repo. See also "DELTA ISLANDS" + in linkgit:git-pack-objects[1]. + +pack.deltaCacheSize:: + The maximum memory in bytes used for caching deltas in + linkgit:git-pack-objects[1] before writing them out to a pack. + This cache is used to speed up the writing object phase by not + having to recompute the final delta result once the best match + for all objects is found. Repacking large repositories on machines + which are tight with memory might be badly impacted by this though, + especially if this cache pushes the system into swapping. + A value of 0 means no limit. The smallest size of 1 byte may be + used to virtually disable this cache. Defaults to 256 MiB. + +pack.deltaCacheLimit:: + The maximum size of a delta, that is cached in + linkgit:git-pack-objects[1]. This cache is used to speed up the + writing object phase by not having to recompute the final delta + result once the best match for all objects is found. + Defaults to 1000. Maximum value is 65535. + +pack.threads:: + Specifies the number of threads to spawn when searching for best + delta matches. This requires that linkgit:git-pack-objects[1] + be compiled with pthreads otherwise this option is ignored with a + warning. This is meant to reduce packing time on multiprocessor + machines. The required amount of memory for the delta search window + is however multiplied by the number of threads. + Specifying 0 will cause Git to auto-detect the number of CPU's + and set the number of threads accordingly. + +pack.indexVersion:: + Specify the default pack index version. Valid values are 1 for + legacy pack index used by Git versions prior to 1.5.2, and 2 for + the new pack index with capabilities for packs larger than 4 GB + as well as proper protection against the repacking of corrupted + packs. Version 2 is the default. Note that version 2 is enforced + and this config option ignored whenever the corresponding pack is + larger than 2 GB. ++ +If you have an old Git that does not understand the version 2 `*.idx` file, +cloning or fetching over a non native protocol (e.g. "http") +that will copy both `*.pack` file and corresponding `*.idx` file from the +other side may give you a repository that cannot be accessed with your +older version of Git. If the `*.pack` file is smaller than 2 GB, however, +you can use linkgit:git-index-pack[1] on the *.pack file to regenerate +the `*.idx` file. + +pack.packSizeLimit:: + The maximum size of a pack. This setting only affects + packing to a file when repacking, i.e. the git:// protocol + is unaffected. It can be overridden by the `--max-pack-size` + option of linkgit:git-repack[1]. Reaching this limit results + in the creation of multiple packfiles; which in turn prevents + bitmaps from being created. + The minimum size allowed is limited to 1 MiB. + The default is unlimited. + Common unit suffixes of 'k', 'm', or 'g' are + supported. + +pack.useBitmaps:: + When true, git will use pack bitmaps (if available) when packing + to stdout (e.g., during the server side of a fetch). Defaults to + true. You should not generally need to turn this off unless + you are debugging pack bitmaps. + +pack.writeBitmaps (deprecated):: + This is a deprecated synonym for `repack.writeBitmaps`. + +pack.writeBitmapHashCache:: + When true, git will include a "hash cache" section in the bitmap + index (if one is written). This cache can be used to feed git's + delta heuristics, potentially leading to better deltas between + bitmapped and non-bitmapped objects (e.g., when serving a fetch + between an older, bitmapped pack and objects that have been + pushed since the last gc). The downside is that it consumes 4 + bytes per object of disk space, and that JGit's bitmap + implementation does not understand it, causing it to complain if + Git and JGit are used on the same repository.
