+Git v2.4.5 Release Notes
+========================
+
+Fixes since v2.4.4
+------------------
+
+ * The setup code used to die when core.bare and core.worktree are set
+ inconsistently, even for commands that do not need working tree.
+
+ * There was a dead code that used to handle "git pull --tags" and
+ show special-cased error message, which was made irrelevant when
+ the semantics of the option changed back in Git 1.9 days.
+
+ * "color.diff.plain" was a misnomer; give it 'color.diff.context' as
+ a more logical synonym.
+
+ * The configuration reader/writer uses mmap(2) interface to access
+ the files; when we find a directory, it barfed with "Out of memory?".
+
+ * Recent "git prune" traverses young unreachable objects to safekeep
+ old objects in the reachability chain from them, which sometimes
+ showed unnecessary error messages that are alarming.
+
+ * "git rebase -i" fired post-rewrite hook when it shouldn't (namely,
+ when it was told to stop sequencing with 'exec' insn).
+
+Also contains typofixes, documentation updates and trivial code

+Git v2.4.7 Release Notes
+========================
+
+Fixes since v2.4.6
+------------------
+
+ * A minor regression to "git fsck" in v2.2 era was fixed; it
+ complained about a body-less tag object when it lacked a
+ separator empty line after its header to separate it with a
+ non-existent body.
+
+ * We used to ask libCURL to use the most secure authentication method
+ available when talking to an HTTP proxy only when we were told to
+ talk to one via configuration variables. We now ask libCURL to
+ always use the most secure authentication method, because the user
+ can tell libCURL to use an HTTP proxy via an environment variable
+ without using configuration variables.
+
+ * When you say "!<ENTER>" while running say "git log", you'd confuse
+ yourself in the resulting shell, that may look as if you took
+ control back to the original shell you spawned "git log" from but
+ that isn't what is happening. To that new shell, we leaked
+ GIT_PAGER_IN_USE environment variable that was meant as a local
+ communication between the original "Git" and subprocesses that was
+ spawned by it after we launched the pager, which caused many
+ "interesting" things to happen, e.g. "git diff | cat" still paints
+ its output in color by default.
+
+ Stop leaking that environment variable to the pager's half of the
+ fork; we only need it on "Git" side when we spawn the pager.
+
+ * Avoid possible ssize_t to int truncation.
+
+ * "git config" failed to update the configuration file when the
+ underlying filesystem is incapable of renaming a file that is still
+ open.
+
+ * A minor bugfix when pack bitmap is used with "rev-list --count".
+
+ * An ancient test framework enhancement to allow color was not
+ entirely correct; this makes it work even when tput needs to read
+ from the ~/.terminfo under the user's real HOME directory.
+
+ * Fix a small bug in our use of umask() return value.
+
+ * "git rebase" did not exit with failure when format-patch it invoked

+Git v2.5.1 Release Notes
+========================
+
+Fixes since v2.5
+----------------
+
+ * Running an aliased command from a subdirectory when the .git thing
+ in the working tree is a gitfile pointing elsewhere did not work.
+
+ * Often a fast-import stream builds a new commit on top of the
+ previous commit it built, and it often unconditionally emits a
+ "from" command to specify the first parent, which can be omitted in
+ such a case. This caused fast-import to forget the tree of the
+ previous commit and then re-read it from scratch, which was
+ inefficient. Optimize for this common case.
+
+ * The "rev-parse --parseopt" mode parsed the option specification
+ and the argument hint in a strange way to allow '=' and other
+ special characters in the option name while forbidding them from
+ the argument hint. This made it impossible to define an option
+ like "--pair <key>=<value>" with "pair=key=value" specification,
+ which instead would have defined a "--pair=key <value>" option.
+
+ * A "rebase" replays changes of the local branch on top of something
+ else, as such they are placed in stage #3 and referred to as
+ "theirs", while the changes in the new base, typically a foreign
+ work, are placed in stage #2 and referred to as "ours". Clarify
+ the "checkout --ours/--theirs".
+
+ * An experimental "untracked cache" feature used uname(2) in a
+ slightly unportable way.
+
+ * "sparse checkout" misbehaved for a path that is excluded from the
+ checkout when switching between branches that differ at the path.
+
+ * The low-level "git send-pack" did not honor 'user.signingkey'
+ configuration variable when sending a signed-push.
+
+ * An attempt to delete a ref by pushing into a repository whose HEAD
+ symbolic reference points at an unborn branch that cannot be
+ created due to ref D/F conflict (e.g. refs/heads/a/b exists, HEAD
+ points at refs/heads/a) failed.
+
+ * "git subtree" (in contrib/) depended on "git log" output to be
+ stable, which was a no-no. Apply a workaround to force a
+ particular date format.
+
+ * "git clone $URL" in recent releases of Git contains a regression in
+ the code that invents a new repository name incorrectly based on
+ the $URL. This has been corrected.

+Git v2.5.2 Release Notes
+========================
+
+Fixes since v2.5.1
+------------------
+
+ * "git init empty && git -C empty log" said "bad default revision 'HEAD'",
+ which was found to be a bit confusing to new users.
+
+ * The "interpret-trailers" helper mistook a multi-paragraph title of
+ a commit log message with a colon in it as the end of the trailer
+ block.
+
+ * When re-priming the cache-tree opportunistically while committing
+ the in-core index as-is, we mistakenly invalidated the in-core
+ index too aggressively, causing the experimental split-index code
+ to unnecessarily rewrite the on-disk index file(s).
+
+ * "git archive" did not use zip64 extension when creating an archive
+ with more than 64k entries, which nobody should need, right ;-)?
+
+ * The code in "multiple-worktree" support that attempted to recover
+ from an inconsistent state updated an incorrect file.
+
+ * "git rev-list" does not take "--notes" option, but did not complain
+ when one is given.
+
+ * Because the configuration system does not allow "alias.0foo" and
+ "pager.0foo" as the configuration key, the user cannot use '0foo'
+ as a custom command name anyway, but "git 0foo" tried to look these
+ keys up and emitted useless warnings before saying '0foo is not a
+ git command'. These warning messages have been squelched.
+
+ * We recently rewrote one of the build scripts in Perl, which made it
+ necessary to have Perl to build Git. Reduced Perl dependency by
+ rewriting it again using sed.
+
+ * t1509 test that requires a dedicated VM environment had some
+ bitrot, which has been corrected.
+
+ * strbuf_read() used to have one extra iteration (and an unnecessary
+ strbuf_grow() of 8kB), which was eliminated.
+
+ * The codepath to produce error messages had a hard-coded limit to
+ the size of the message, primarily to avoid memory allocation while
+ calling die().
+
+ * When trying to see that an object does not exist, a state errno
+ leaked from our "first try to open a packfile with O_NOATIME and
+ then if it fails retry without it" logic on a system that refuses
+ O_NOATIME. This confused us and caused us to die, saying that the
+ packfile is unreadable, when we should have just reported that the
+ object does not exist in that packfile to the caller.
+
+ * An off-by-one error made "git remote" to mishandle a remote with a
+ single letter nickname.
+
+ * A handful of codepaths that used to use fixed-sized arrays to hold
+ pathnames have been corrected to use strbuf and other mechanisms to
+ allow longer pathnames without fearing overflows.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+========================

+ * Recent versions of scripted "git am" has a performance regression
+ in "git am --skip" codepath, which no longer exists in the
+ built-in version on the 'master' front. Fix the regression in
+ the last scripted version that appear in 2.5.x maintenance track

+Git 2.6 Release Notes
+=====================
+
+Updates since v2.5
+------------------
+
+UI, Workflows & Features
+
+ * An asterisk as a substring (as opposed to the entirety) of a path
+ component for both side of a refspec, e.g.
+ "refs/heads/o*:refs/remotes/heads/i*", is now allowed.
+
+ * New userdiff pattern definition for fountain screenwriting markup
+ format has been added.
+
+ * "git log" and friends learned a new "--date=format:..." option to
+ format timestamps using system's strftime(3).
+
+ * "git fast-import" learned to respond to the get-mark command via
+ its cat-blob-fd interface.
+
+ * "git rebase -i" learned "drop commit-object-name subject" command
+ as another way to skip replaying of a commit.
+
+ * A new configuration variable can enable "--follow" automatically
+ when "git log" is run with one pathspec argument.
+
+ * "git status" learned to show a more detailed information regarding
+ the "rebase -i" session in progress.
+
+ * "git cat-file" learned "--batch-all-objects" option to enumerate all
+ available objects in the repository more quickly than "rev-list
+ --all --objects" (the output includes unreachable objects, though).
+
+ * "git fsck" learned to ignore errors on a set of known-to-be-bad
+ objects, and also allows the warning levels of various kinds of
+ non-critical breakages to be tweaked.
+
+ * "git rebase -i"'s list of todo is made configurable.
+
+ * "git send-email" now performs alias-expansion on names that are
+ given via --cccmd, etc.
+
+ * An environment variable GIT_REPLACE_REF_BASE tells Git to look into
+ refs hierarchy other than refs/replace/ for the object replacement
+ data.
+
+ * Allow untracked cache (experimental) to be used when sparse
+ checkout (experimental) is also in use.
+
+ * "git pull --rebase" has been taught to pay attention to
+ rebase.autostash configuration.
+
+ * The command-line completion script (in contrib/) has been updated.
+
+ * A negative !ref entry in multi-value transfer.hideRefs
+ configuration can be used to say "don't hide this one".
+
+ * After "git am" without "-3" stops, running "git am -3" pays attention
+ to "-3" only for the patch that caused the original invocation
+ to stop.
+
+ * When linked worktree is used, simultaneous "notes merge" instances
+ for the same ref in refs/notes/* are prevented from stomping on
+ each other.
+
+ * "git send-email" learned a new option --smtp-auth to limit the SMTP
+ AUTH mechanisms to be used to a subset of what the system library
+ supports.
+
+ * A new configuration variable http.sslVersion can be used to specify
+ what specific version of SSL/TLS to use to make a connection.
+
+ * "git notes merge" can be told with "--strategy=<how>" option how to
+ automatically handle conflicts; this can now be configured by
+ setting notes.mergeStrategy configuration variable.
+
+ * "git log --cc" did not show any patch, even though most of the time
+ the user meant "git log --cc -p -m" to see patch output for commits
+ with a single parent, and combined diff for merge commits. The
+ command is taught to DWIM "--cc" (without "--raw" and other forms
+ of output specification) to "--cc -p -m".
+
+ * "git config --list" output was hard to parse when values consist of
+ multiple lines. "--name-only" option is added to help this.
+
+ * A handful of usability & cosmetic fixes to gitk and l10n updates.
+
+ * A completely empty e-mail address <> is now allowed in the authors
+ file used by git-svn, to match the way it accepts the output from
+ authors-prog.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * In preparation for allowing different "backends" to store the refs
+ in a way different from the traditional "one ref per file in
+ $GIT_DIR or in a $GIT_DIR/packed-refs file" filesystem storage,
+ direct filesystem access to ref-like things like CHERRY_PICK_HEAD
+ from scripts and programs has been reduced.
+
+ * Computation of untracked status indicator by bash prompt
+ script (in contrib/) has been optimized.
+
+ * Memory use reduction when commit-slab facility is used to annotate
+ sparsely (which is not recommended in the first place).
+
+ * Clean up refs API and make "git clone" less intimate with the
+ implementation detail.
+
+ * "git pull" was reimplemented in C.
+
+ * The packet tracing machinery allows to capture an incoming pack
+ data to a file for debugging.
+
+ * Move machinery to parse human-readable scaled numbers like 1k, 4M,
+ and 2G as an option parameter's value from pack-objects to
+ parse-options API, to make it available to other codepaths.
+
+ * "git verify-tag" and "git verify-commit" have been taught to share
+ more code, and then learned to optionally show the verification
+ message from the underlying GPG implementation.
+
+ * Various enhancements around "git am" reading patches generated by
+ foreign SCM have been made.
+
+ * Ref listing by "git branch -l" and "git tag -l" commands has
+ started to be rebuilt, based on the for-each-ref machinery.
+
+ * The code to perform multi-tree merges has been taught to repopulate
+ the cache-tree upon a successful merge into the index, so that
+ subsequent "diff-index --cached" (hence "status") and "write-tree"
+ (hence "commit") will go faster.
+
+ The same logic in "git checkout" may now be removed, but that is a
+ separate issue.
+
+ * Tests that assume how reflogs are represented on the filesystem too
+ much have been corrected.
+
+ * "git am" has been rewritten in "C".
+
+ * git_path() and mkpath() are handy helper functions but it is easy
+ to misuse, as the callers need to be careful to keep the number of
+ active results below 4. Their uses have been reduced.
+
+ * The "lockfile" API has been rebuilt on top of a new "tempfile" API.
+
+ * To prepare for allowing a different "ref" backend to be plugged in
+ to the system, update_ref()/delete_ref() have been taught about
+ ref-like things like MERGE_HEAD that are per-worktree (they will
+ always be written to the filesystem inside $GIT_DIR).
+
+ * The gitmodules API that is accessed from the C code learned to
+ cache stuff lazily.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.5
+----------------
+
+Unless otherwise noted, all the fixes since v2.5 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git subtree" (in contrib/) depended on "git log" output to be
+ stable, which was a no-no. Apply a workaround to force a
+ particular date format.
+ (merge e7aac44 da/subtree-date-confusion later to maint).
+
+ * An attempt to delete a ref by pushing into a repository whose HEAD
+ symbolic reference points at an unborn branch that cannot be
+ created due to ref D/F conflict (e.g. refs/heads/a/b exists, HEAD
+ points at refs/heads/a) failed.
+ (merge b112b14 jx/do-not-crash-receive-pack-wo-head later to maint).
+
+ * The low-level "git send-pack" did not honor 'user.signingkey'
+ configuration variable when sending a signed-push.
+ (merge d830d39 db/send-pack-user-signingkey later to maint).
+
+ * "sparse checkout" misbehaved for a path that is excluded from the
+ checkout when switching between branches that differ at the path.
+ (merge 7d78241 as/sparse-checkout-removal later to maint).
+
+ * An experimental "untracked cache" feature used uname(2) in a
+ slightly unportable way.
+ (merge 100e433 cb/uname-in-untracked later to maint).
+
+ * A "rebase" replays changes of the local branch on top of something
+ else, as such they are placed in stage #3 and referred to as
+ "theirs", while the changes in the new base, typically a foreign
+ work, are placed in stage #2 and referred to as "ours". Clarify
+ the "checkout --ours/--theirs".
+ (merge f303016 se/doc-checkout-ours-theirs later to maint).
+
+ * The "rev-parse --parseopt" mode parsed the option specification
+ and the argument hint in a strange way to allow '=' and other
+ special characters in the option name while forbidding them from
+ the argument hint. This made it impossible to define an option
+ like "--pair <key>=<value>" with "pair=key=value" specification,
+ which instead would have defined a "--pair=key <value>" option.
+ (merge 2d893df ib/scripted-parse-opt-better-hint-string later to maint).
+
+ * Often a fast-import stream builds a new commit on top of the
+ previous commit it built, and it often unconditionally emits a
+ "from" command to specify the first parent, which can be omitted in
+ such a case. This caused fast-import to forget the tree of the
+ previous commit and then re-read it from scratch, which was
+ inefficient. Optimize for this common case.
+ (merge 0df3245 mh/fast-import-optimize-current-from later to maint).
+
+ * Running an aliased command from a subdirectory when the .git thing
+ in the working tree is a gitfile pointing elsewhere did not work.
+ (merge d95138e nd/export-worktree later to maint).
+
+ * "Is this subdirectory a separate repository that should not be
+ touched?" check "git clean" was inefficient. This was replaced
+ with a more optimized check.
+ (merge fbf2fec ee/clean-remove-dirs later to maint).
+
+ * The "new-worktree-mode" hack in "checkout" that was added in
+ nd/multiple-work-trees topic has been removed by updating the
+ implementation of new "worktree add".
+ (merge 65f9b75 es/worktree-add-cleanup later to maint).
+
+ * Remove remaining cruft from "git checkout --to", which
+ transitioned to "git worktree add".
+ (merge 114ff88 es/worktree-add later to maint).
+
+ * An off-by-one error made "git remote" to mishandle a remote with a
+ single letter nickname.
+ (merge bc598c3 mh/get-remote-group-fix later to maint).
+
+ * "git clone $URL", when cloning from a site whose sole purpose is to
+ host a single repository (hence, no path after <scheme>://<site>/),
+ tried to use the site name as the new repository name, but did not
+ remove username or password when <site> part was of the form
+ <user>@<pass>:<host>. The code is taught to redact these.
+ (merge adef956 ps/guess-repo-name-at-root later to maint).
+
+ * Running tests with the "-x" option to make them verbose had some
+ unpleasant interactions with other features of the test suite.
+ (merge 9b5fe78 jk/test-with-x later to maint).
+
+ * t1509 test that requires a dedicated VM environment had some
+ bitrot, which has been corrected.
+ (merge faacc5a ps/t1509-chroot-test-fixup later to maint).
+
+ * "git pull" in recent releases of Git has a regression in the code
+ that allows custom path to the --upload-pack=<program>. This has
+ been corrected.
+
+ Note that this is irrelevant for 'master' with "git pull" rewritten
+ in C.
+ (merge 13e0e28 mm/pull-upload-pack later to maint).
+
+ * When trying to see that an object does not exist, a state errno
+ leaked from our "first try to open a packfile with O_NOATIME and
+ then if it fails retry without it" logic on a system that refuses
+ O_NOATIME. This confused us and caused us to die, saying that the
+ packfile is unreadable, when we should have just reported that the
+ object does not exist in that packfile to the caller.
+ (merge dff6f28 cb/open-noatime-clear-errno later to maint).
+
+ * The codepath to produce error messages had a hard-coded limit to
+ the size of the message, primarily to avoid memory allocation while
+ calling die().
+ (merge f4c3edc jk/long-error-messages later to maint).
+
+ * strbuf_read() used to have one extra iteration (and an unnecessary
+ strbuf_grow() of 8kB), which was eliminated.
+ (merge 3ebbd00 jh/strbuf-read-use-read-in-full later to maint).
+
+ * We rewrote one of the build scripts in Perl but this reimplements
+ in Bourne shell.
+ (merge 57cee8a sg/help-group later to maint).
+
+ * The experimental untracked-cache feature were buggy when paths with
+ a few levels of subdirectories are involved.
+ (merge 73f9145 dt/untracked-subdir later to maint).
+
+ * "interpret-trailers" helper mistook a single-liner log message that
+ has a colon as the end of existing trailer.
+
+ * The "interpret-trailers" helper mistook a multi-paragraph title of
+ a commit log message with a colon in it as the end of the trailer
+ block.
+ (merge 5c99995 cc/trailers-corner-case-fix later to maint).
+
+ * "git describe" without argument defaulted to describe the HEAD
+ commit, but "git describe --contains" didn't. Arguably, in a
+ repository used for active development, such defaulting would not
+ be very useful as the tip of branch is typically not tagged, but it
+ is better to be consistent.
+ (merge 2bd0706 sg/describe-contains later to maint).
+
+ * The client side codepaths in "git push" have been cleaned up
+ and the user can request to perform an optional "signed push",
+ i.e. sign only when the other end accepts signed push.
+ (merge 68c757f db/push-sign-if-asked later to maint).
+
+ * Because the configuration system does not allow "alias.0foo" and
+ "pager.0foo" as the configuration key, the user cannot use '0foo'
+ as a custom command name anyway, but "git 0foo" tried to look these
+ keys up and emitted useless warnings before saying '0foo is not a
+ git command'. These warning messages have been squelched.
+ (merge 9e9de18 jk/fix-alias-pager-config-key-warnings later to maint).
+
+ * "git rev-list" does not take "--notes" option, but did not complain
+ when one is given.
+ (merge 2aea7a5 jk/rev-list-has-no-notes later to maint).
+
+ * When re-priming the cache-tree opportunistically while committing
+ the in-core index as-is, we mistakenly invalidated the in-core
+ index too aggressively, causing the experimental split-index code
+ to unnecessarily rewrite the on-disk index file(s).
+ (merge 475a344 dt/commit-preserve-base-index-upon-opportunistic-cache-tree-update later to maint).
+
+ * "git archive" did not use zip64 extension when creating an archive
+ with more than 64k entries, which nobody should need, right ;-)?
+ (merge 88329ca rs/archive-zip-many later to maint).
+
+ * The code in "multiple-worktree" support that attempted to recover
+ from an inconsistent state updated an incorrect file.
+ (merge 82fde87 nd/fixup-linked-gitdir later to maint).
+
+ * On case insensitive systems, "git p4" did not work well with client
+ specs.
+
+ * "git init empty && git -C empty log" said "bad default revision 'HEAD'",
+ which was found to be a bit confusing to new users.
+ (merge ce11360 jk/log-missing-default-HEAD later to maint).
+
+ * Recent versions of scripted "git am" has a performance regression in
+ "git am --skip" codepath, which no longer exists in the built-in
+ version on the 'master' front. Fix the regression in the last
+ scripted version that appear in 2.5.x maintenance track and older.
+ (merge b9d6689 js/maint-am-skip-performance-regression later to maint).

-Use "git bisect" to get a short usage description, and "git bisect
-help" or "git bisect -h" to get a long usage description.
+This command uses a binary search algorithm to find which commit in
+your project's history introduced a bug. You use it by first telling
+it a "bad" commit that is known to contain the bug, and a "good"
+commit that is known to be before the bug was introduced. Then `git
+bisect` picks a commit between those two endpoints and asks you
+whether the selected commit is "good" or "bad". It continues narrowing
+down the range until it finds the exact commit that introduced the
+change.
Basic bisect commands: start, bad, good
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Using the Linux kernel tree as an example, basic use of the bisect
-command is as follows:
+As an example, suppose you are trying to find the commit that broke a
+feature that was known to work in version `v2.6.13-rc2` of your
+project. You start a bisect session as follows:
------------------------------------------------
$ git bisect start
$ git bisect bad # Current version is bad
-$ git bisect good v2.6.13-rc2 # v2.6.13-rc2 was the last version
- # tested that was good
+$ git bisect good v2.6.13-rc2 # v2.6.13-rc2 is known to be good
------------------------------------------------
-When you have specified at least one bad and one good version, the
-command bisects the revision tree and outputs something similar to
-the following:
+Once you have specified at least one bad and one good commit, `git
+bisect` selects a commit in the middle of that range of history,
+checks it out, and outputs something similar to the following:

-You keep repeating this process, compiling the tree, testing it, and

------------
-MULTIPLE WORKING TREES
-----------------------
-
-A git repository can support multiple working trees, allowing you to check
-out more than one branch at a time. With `git checkout --to` a new working
-tree is associated with the repository. This new working tree is called a
-"linked working tree" as opposed to the "main working tree" prepared by "git
-init" or "git clone". A repository has one main working tree (if it's not a
-bare repository) and zero or more linked working trees.
-
-Each linked working tree has a private sub-directory in the repository's
-$GIT_DIR/worktrees directory. The private sub-directory's name is usually
-the base name of the linked working tree's path, possibly appended with a
-number to make it unique. For example, when `$GIT_DIR=/path/main/.git` the
-command `git checkout --to /path/other/test-next next` creates the linked
-working tree in `/path/other/test-next` and also creates a
-`$GIT_DIR/worktrees/test-next` directory (or `$GIT_DIR/worktrees/test-next1`
-if `test-next` is already taken).
-
-Within a linked working tree, $GIT_DIR is set to point to this private
-directory (e.g. `/path/main/.git/worktrees/test-next` in the example) and
-$GIT_COMMON_DIR is set to point back to the main working tree's $GIT_DIR
-(e.g. `/path/main/.git`). These settings are made in a `.git` file located at
-the top directory of the linked working tree.
-
-Path resolution via `git rev-parse --git-path` uses either
-$GIT_DIR or $GIT_COMMON_DIR depending on the path. For example, in the
-linked working tree `git rev-parse --git-path HEAD` returns
-`/path/main/.git/worktrees/test-next/HEAD` (not
-`/path/other/test-next/.git/HEAD` or `/path/main/.git/HEAD`) while `git
-rev-parse --git-path refs/heads/master` uses
-$GIT_COMMON_DIR and returns `/path/main/.git/refs/heads/master`,
-since refs are shared across all working trees.
-
-See linkgit:gitrepository-layout[5] for more information. The rule of
-thumb is do not make any assumption about whether a path belongs to
-$GIT_DIR or $GIT_COMMON_DIR when you need to directly access something
-inside $GIT_DIR. Use `git rev-parse --git-path` to get the final path.
-
-When you are done with a linked working tree you can simply delete it.
-The working tree's entry in the repository's $GIT_DIR/worktrees
-directory will eventually be removed automatically (see
-`gc.pruneworktreesexpire` in linkgit::git-config[1]), or you can run
-`git prune --worktrees` in the main or any linked working tree to
-clean up any stale entries in $GIT_DIR/worktrees.
-
-If you move a linked working directory to another file system, or
-within a file system that does not support hard links, you need to run
-at least one git command inside the linked working directory
-(e.g. `git status`) in order to update its entry in $GIT_DIR/worktrees
-so that it does not get automatically removed.
-
-To prevent a $GIT_DIR/worktrees entry from from being pruned (which
-can be useful in some situations, such as when the
-entry's working tree is stored on a portable device), add a file named
-'locked' to the entry's directory. The file contains the reason in
-plain text. For example, if a linked working tree's `.git` file points
-to `/path/main/.git/worktrees/test-next` then a file named
-`/path/main/.git/worktrees/test-next/locked` will prevent the
-`test-next` entry from being pruned. See
-linkgit:gitrepository-layout[5] for details.
-
-Multiple checkout support for submodules is incomplete. It is NOT
-recommended to make multiple checkouts of a superproject.

-A short Git tools survey
-========================
+Git Tools
+=========
+When Git was young, people looking for third-party Git-related tools came
+to the Git project itself to find them, thus a list of such tools was
+maintained here. These days, however, search engines fill that role much
+more efficiently, so this manually-maintained list has been retired.
-Introduction
-------------
-
-Apart from Git contrib/ area there are some others third-party tools
-you may want to look.
-
-This document presents a brief summary of each tool and the corresponding
-link.
-
-
-Alternative/Augmentative Porcelains
------------------------------------
-
- - *Cogito* (http://www.kernel.org/pub/software/scm/cogito/)
-
- Cogito is a version control system layered on top of the Git tree history
- storage system. It aims at seamless user interface and ease of use,
- providing generally smoother user experience than the "raw" Core Git
- itself and indeed many other version control systems.
-
- Cogito is no longer maintained as most of its functionality
- is now in core Git.
-
-
- - *pg* (http://www.spearce.org/category/projects/scm/pg/)
-
- pg is a shell script wrapper around Git to help the user manage a set of
- patches to files. pg is somewhat like quilt or StGit, but it does have a
- slightly different feature set.
-
-
- - *StGit* (http://www.procode.org/stgit/)
-
- Stacked Git provides a quilt-like patch management functionality in the
- Git environment. You can easily manage your patches in the scope of Git
- until they get merged upstream.
-
-
-History Viewers
----------------
-
- - *gitk* (shipped with git-core)
-
- gitk is a simple Tk GUI for browsing history of Git repositories easily.
-
-
- - *gitview* (contrib/)
-
- gitview is a GTK based repository browser for Git
-
-
- - *gitweb* (shipped with git-core)
-
- Gitweb provides full-fledged web interface for Git repositories.
-
-
- - *qgit* (http://digilander.libero.it/mcostalba/)
-
- QGit is a git/StGit GUI viewer built on Qt/C++. QGit could be used
- to browse history and directory tree, view annotated files, commit
- changes cherry picking single files or applying patches.
- Currently it is the fastest and most feature rich among the Git
- viewers and commit tools.
-
- - *tig* (http://jonas.nitro.dk/tig/)
-
- tig by Jonas Fonseca is a simple Git repository browser
- written using ncurses. Basically, it just acts as a front-end
- for git-log and git-show/git-diff. Additionally, you can also
- use it as a pager for Git commands.
-
-
-Foreign SCM interface
----------------------
-
- - *git-svn* (shipped with git-core)
-
- git-svn is a simple conduit for changesets between a single Subversion
- branch and Git.
-
-
- - *quilt2git / git2quilt* (http://home-tj.org/wiki/index.php/Misc)
-
- These utilities convert patch series in a quilt repository and commit
- series in Git back and forth.
-
-
- - *hg-to-git* (contrib/)
-
- hg-to-git converts a Mercurial repository into a Git one, and
- preserves the full branch history in the process. hg-to-git can
- also be used in an incremental way to keep the Git repository
- in sync with the master Mercurial repository.

+NAME
+----
+git-worktree - Manage multiple working trees
+
+
+SYNOPSIS
+--------
+[verse]
+'git worktree add' [-f] [--detach] [-b <new-branch>] <path> [<branch>]
+'git worktree prune' [-n] [-v] [--expire <expire>]
+
+DESCRIPTION
+-----------
+
+Manage multiple working trees attached to the same repository.
+
+A git repository can support multiple working trees, allowing you to check
+out more than one branch at a time. With `git worktree add` a new working
+tree is associated with the repository. This new working tree is called a
+"linked working tree" as opposed to the "main working tree" prepared by "git
+init" or "git clone". A repository has one main working tree (if it's not a
+bare repository) and zero or more linked working trees.
+
+When you are done with a linked working tree you can simply delete it.
+The working tree's administrative files in the repository (see
+"DETAILS" below) will eventually be removed automatically (see
+`gc.worktreePruneExpire` in linkgit:git-config[1]), or you can run
+`git worktree prune` in the main or any linked working tree to
+clean up any stale administrative files.
+
+If you move a linked working tree to another file system, or
+within a file system that does not support hard links, you need to run
+at least one git command inside the linked working tree
+(e.g. `git status`) in order to update its administrative files in the
+repository so that they do not get automatically pruned.
+
+If a linked working tree is stored on a portable device or network share
+which is not always mounted, you can prevent its administrative files from
+being pruned by creating a file named 'locked' alongside the other
+administrative files, optionally containing a plain text reason that
+pruning should be suppressed. See section "DETAILS" for more information.
+
+COMMANDS
+--------
+add <path> [<branch>]::
+
+Create `<path>` and checkout `<branch>` into it. The new working directory
+is linked to the current repository, sharing everything except working
+directory specific files such as HEAD, index, etc.
++
+If `<branch>` is omitted and neither `-b` nor `-B` nor `--detached` used,
+then, as a convenience, a new branch based at HEAD is created automatically,
+as if `-b $(basename <path>)` was specified.
+
+prune::
+
+Prune working tree information in $GIT_DIR/worktrees.
+
+OPTIONS
+-------
+
+-f::
+--force::
+ By default, `add` refuses to create a new working tree when `<branch>`
+ is already checked out by another working tree. This option overrides
+ that safeguard.
+
+-b <new-branch>::
+-B <new-branch>::
+ With `add`, create a new branch named `<new-branch>` starting at
+ `<branch>`, and check out `<new-branch>` into the new working tree.
+ If `<branch>` is omitted, it defaults to HEAD.
+ By default, `-b` refuses to create a new branch if it already
+ exists. `-B` overrides this safeguard, resetting `<new-branch>` to
+ `<branch>`.
+
+--detach::
+ With `add`, detach HEAD in the new working tree. See "DETACHED HEAD"
+ in linkgit:git-checkout[1].
+
+-n::
+--dry-run::
+ With `prune`, do not remove anything; just report what it would
+ remove.
+
+-v::
+--verbose::
+ With `prune`, report all removals.
+
+--expire <time>::
+ With `prune`, only expire unused working trees older than <time>.
+
+DETAILS
+-------
+Each linked working tree has a private sub-directory in the repository's
+$GIT_DIR/worktrees directory. The private sub-directory's name is usually
+the base name of the linked working tree's path, possibly appended with a
+number to make it unique. For example, when `$GIT_DIR=/path/main/.git` the
+command `git worktree add /path/other/test-next next` creates the linked
+working tree in `/path/other/test-next` and also creates a
+`$GIT_DIR/worktrees/test-next` directory (or `$GIT_DIR/worktrees/test-next1`
+if `test-next` is already taken).
+
+Within a linked working tree, $GIT_DIR is set to point to this private
+directory (e.g. `/path/main/.git/worktrees/test-next` in the example) and
+$GIT_COMMON_DIR is set to point back to the main working tree's $GIT_DIR
+(e.g. `/path/main/.git`). These settings are made in a `.git` file located at
+the top directory of the linked working tree.
+
+Path resolution via `git rev-parse --git-path` uses either
+$GIT_DIR or $GIT_COMMON_DIR depending on the path. For example, in the
+linked working tree `git rev-parse --git-path HEAD` returns
+`/path/main/.git/worktrees/test-next/HEAD` (not
+`/path/other/test-next/.git/HEAD` or `/path/main/.git/HEAD`) while `git
+rev-parse --git-path refs/heads/master` uses
+$GIT_COMMON_DIR and returns `/path/main/.git/refs/heads/master`,
+since refs are shared across all working trees.
+
+See linkgit:gitrepository-layout[5] for more information. The rule of
+thumb is do not make any assumption about whether a path belongs to
+$GIT_DIR or $GIT_COMMON_DIR when you need to directly access something
+inside $GIT_DIR. Use `git rev-parse --git-path` to get the final path.
+
+To prevent a $GIT_DIR/worktrees entry from being pruned (which
+can be useful in some situations, such as when the
+entry's working tree is stored on a portable device), add a file named
+'locked' to the entry's directory. The file contains the reason in
+plain text. For example, if a linked working tree's `.git` file points
+to `/path/main/.git/worktrees/test-next` then a file named
+`/path/main/.git/worktrees/test-next/locked` will prevent the
+`test-next` entry from being pruned. See
+linkgit:gitrepository-layout[5] for details.
+
+EXAMPLES
+--------
+You are in the middle of a refactoring session and your boss comes in and
+demands that you fix something immediately. You might typically use
+linkgit:git-stash[1] to store your changes away temporarily, however, your
+working tree is in such a state of disarray (with new, moved, and removed
+files, and other bits and pieces strewn around) that you don't want to risk
+disturbing any of it. Instead, you create a temporary linked working tree to
+make the emergency fix, remove it when done, and then resume your earlier
+refactoring session.
+
+------------
+$ git worktree add -b emergency-fix ../temp master
+$ pushd ../temp
+# ... hack hack hack ...
+$ git commit -a -m 'emergency fix for boss'
+$ popd
+$ rm -rf ../temp
+$ git worktree prune
+------------
+
+BUGS
+----
+Multiple checkout in general is still experimental, and the support
+for submodules is incomplete. It is NOT recommended to make multiple
+checkouts of a superproject.
+
+git-worktree could provide more automation for tasks currently
+performed manually, such as:
+
+- `remove` to remove a linked working tree and its administrative files (and
+ warn if the working tree is dirty)
+- `mv` to move or rename a working tree and update its administrative files
+- `list` to list linked working trees
+- `lock` to prevent automatic pruning of administrative files (for instance,
+ for a working tree on a portable device)

-lockfile API
-============
-
-The lockfile API serves two purposes:
-
-* Mutual exclusion and atomic file updates. When we want to change a
- file, we create a lockfile `<filename>.lock`, write the new file
- contents into it, and then rename the lockfile to its final
- destination `<filename>`. We create the `<filename>.lock` file with
- `O_CREAT|O_EXCL` so that we can notice and fail if somebody else has
- already locked the file, then atomically rename the lockfile to its
- final destination to commit the changes and unlock the file.
-
-* Automatic cruft removal. If the program exits after we lock a file
- but before the changes have been committed, we want to make sure
- that we remove the lockfile. This is done by remembering the
- lockfiles we have created in a linked list and setting up an
- `atexit(3)` handler and a signal handler that clean up the
- lockfiles. This mechanism ensures that outstanding lockfiles are
- cleaned up if the program exits (including when `die()` is called)
- or if the program dies on a signal.
-
-Please note that lockfiles only block other writers. Readers do not
-block, but they are guaranteed to see either the old contents of the
-file or the new contents of the file (assuming that the filesystem
-implements `rename(2)` atomically).
-
-
-Calling sequence
-----------------
-
-The caller:
-
-* Allocates a `struct lock_file` either as a static variable or on the
- heap, initialized to zeros. Once you use the structure to call the
- `hold_lock_file_*` family of functions, it belongs to the lockfile
- subsystem and its storage must remain valid throughout the life of
- the program (i.e. you cannot use an on-stack variable to hold this
- structure).
-
-* Attempts to create a lockfile by passing that variable and the path
- of the final destination (e.g. `$GIT_DIR/index`) to
- `hold_lock_file_for_update` or `hold_lock_file_for_append`.
-
-* Writes new content for the destination file by either:
-
- * writing to the file descriptor returned by the `hold_lock_file_*`
- functions (also available via `lock->fd`).
-
- * calling `fdopen_lock_file` to get a `FILE` pointer for the open
- file and writing to the file using stdio.
-
-When finished writing, the caller can:
-
-* Close the file descriptor and rename the lockfile to its final
- destination by calling `commit_lock_file` or `commit_lock_file_to`.
-
-* Close the file descriptor and remove the lockfile by calling
- `rollback_lock_file`.
-
-* Close the file descriptor without removing or renaming the lockfile
- by calling `close_lock_file`, and later call `commit_lock_file`,
- `commit_lock_file_to`, `rollback_lock_file`, or `reopen_lock_file`.
-
-Even after the lockfile is committed or rolled back, the `lock_file`
-object must not be freed or altered by the caller. However, it may be
-reused; just pass it to another call of `hold_lock_file_for_update` or
-`hold_lock_file_for_append`.
-
-If the program exits before you have called one of `commit_lock_file`,
-`commit_lock_file_to`, `rollback_lock_file`, or `close_lock_file`, an
-`atexit(3)` handler will close and remove the lockfile, rolling back
-any uncommitted changes.
-
-If you need to close the file descriptor you obtained from a
-`hold_lock_file_*` function yourself, do so by calling
-`close_lock_file`. You should never call `close(2)` or `fclose(3)`
-yourself! Otherwise the `struct lock_file` structure would still think
-that the file descriptor needs to be closed, and a commit or rollback
-would result in duplicate calls to `close(2)`. Worse yet, if you close
-and then later open another file descriptor for a completely different
-purpose, then a commit or rollback might close that unrelated file
-descriptor.
-
-
-Error handling
---------------
-
-The `hold_lock_file_*` functions return a file descriptor on success
-or -1 on failure (unless `LOCK_DIE_ON_ERROR` is used; see below). On
-errors, `errno` describes the reason for failure. Errors can be
-reported by passing `errno` to one of the following helper functions:
-
-unable_to_lock_message::
-
- Append an appropriate error message to a `strbuf`.
-
-unable_to_lock_error::
-
- Emit an appropriate error message using `error()`.
-
-unable_to_lock_die::
-
- Emit an appropriate error message and `die()`.
-
-Similarly, `commit_lock_file`, `commit_lock_file_to`, and
-`close_lock_file` return 0 on success. On failure they set `errno`
-appropriately, do their best to roll back the lockfile, and return -1.
-
-
-Flags
------
-
-The following flags can be passed to `hold_lock_file_for_update` or
-`hold_lock_file_for_append`:
-
-LOCK_NO_DEREF::
-
- Usually symbolic links in the destination path are resolved
- and the lockfile is created by adding ".lock" to the resolved
- path. If `LOCK_NO_DEREF` is set, then the lockfile is created
- by adding ".lock" to the path argument itself. This option is
- used, for example, when locking a symbolic reference, which
- for backwards-compatibility reasons can be a symbolic link
- containing the name of the referred-to-reference.
-
-LOCK_DIE_ON_ERROR::
-
- If a lock is already taken for the file, `die()` with an error
- message. If this option is not specified, trying to lock a
- file that is already locked returns -1 to the caller.
-
-
-The functions
--------------
-
-hold_lock_file_for_update::
-
- Take a pointer to `struct lock_file`, the path of the file to
- be locked (e.g. `$GIT_DIR/index`) and a flags argument (see
- above). Attempt to create a lockfile for the destination and
- return the file descriptor for writing to the file.
-
-hold_lock_file_for_append::
-
- Like `hold_lock_file_for_update`, but before returning copy
- the existing contents of the file (if any) to the lockfile and
- position its write pointer at the end of the file.
-
-fdopen_lock_file::
-
- Associate a stdio stream with the lockfile. Return NULL
- (*without* rolling back the lockfile) on error. The stream is
- closed automatically when `close_lock_file` is called or when
- the file is committed or rolled back.
-
-get_locked_file_path::
-
- Return the path of the file that is locked by the specified
- lock_file object. The caller must free the memory.
-
-commit_lock_file::
-
- Take a pointer to the `struct lock_file` initialized with an
- earlier call to `hold_lock_file_for_update` or
- `hold_lock_file_for_append`, close the file descriptor, and
- rename the lockfile to its final destination. Return 0 upon
- success. On failure, roll back the lock file and return -1,
- with `errno` set to the value from the failing call to
- `close(2)` or `rename(2)`. It is a bug to call
- `commit_lock_file` for a `lock_file` object that is not
- currently locked.
-
-commit_lock_file_to::
-
- Like `commit_lock_file()`, except that it takes an explicit
- `path` argument to which the lockfile should be renamed. The
- `path` must be on the same filesystem as the lock file.
-
-rollback_lock_file::
-
- Take a pointer to the `struct lock_file` initialized with an
- earlier call to `hold_lock_file_for_update` or
- `hold_lock_file_for_append`, close the file descriptor and
- remove the lockfile. It is a NOOP to call
- `rollback_lock_file()` for a `lock_file` object that has
- already been committed or rolled back.
-
-close_lock_file::
-
- Take a pointer to the `struct lock_file` initialized with an
- earlier call to `hold_lock_file_for_update` or
- `hold_lock_file_for_append`. Close the file descriptor (and
- the file pointer if it has been opened using
- `fdopen_lock_file`). Return 0 upon success. On failure to
- `close(2)`, return a negative value and roll back the lock
- file. Usually `commit_lock_file`, `commit_lock_file_to`, or
- `rollback_lock_file` should eventually be called if
- `close_lock_file` succeeds.
-
-reopen_lock_file::
-
- Re-open a lockfile that has been closed (using
- `close_lock_file`) but not yet committed or rolled back. This
- can be used to implement a sequence of operations like the
- following:
-
- * Lock file.
-
- * Write new contents to lockfile, then `close_lock_file` to
- cause the contents to be written to disk.
-
- * Pass the name of the lockfile to another program to allow it
- (and nobody else) to inspect the contents you wrote, while
- still holding the lock yourself.
-
- * `reopen_lock_file` to reopen the lockfile. Make further
- updates to the contents.
-
- * `commit_lock_file` to make the final version permanent.

+submodule config cache API
+==========================
+
+The submodule config cache API allows to read submodule
+configurations/information from specified revisions. Internally
+information is lazily read into a cache that is used to avoid
+unnecessary parsing of the same .gitmodule files. Lookups can be done by
+submodule path or name.
+
+Usage
+-----
+
+To initialize the cache with configurations from the worktree the caller
+typically first calls `gitmodules_config()` to read values from the
+worktree .gitmodules and then to overlay the local git config values
+`parse_submodule_config_option()` from the config parsing
+infrastructure.
+
+The caller can look up information about submodules by using the
+`submodule_from_path()` or `submodule_from_name()` functions. They return
+a `struct submodule` which contains the values. The API automatically
+initializes and allocates the needed infrastructure on-demand. If the
+caller does only want to lookup values from revisions the initialization
+can be skipped.
+
+If the internal cache might grow too big or when the caller is done with
+the API, all internally cached values can be freed with submodule_free().
+
+Data Structures
+---------------
+
+`struct submodule`::
+
+ This structure is used to return the information about one
+ submodule for a certain revision. It is returned by the lookup
+ functions.
+
+Functions
+---------
+
+`void submodule_free()`::
+
+ Use these to free the internally cached values.
+
+`int parse_submodule_config_option(const char *var, const char *value)`::
+
+ Can be passed to the config parsing infrastructure to parse
+ local (worktree) submodule configurations.
+
+`const struct submodule *submodule_from_path(const unsigned char *commit_sha1, const char *path)`::
+
+ Lookup values for one submodule by its commit_sha1 and path.
+
+`const struct submodule *submodule_from_name(const unsigned char *commit_sha1, const char *name)`::
+
+ The same as above but lookup by name.
+
+If given the null_sha1 as commit_sha1 the local configuration of a
+submodule will be returned (e.g. consolidated values from local git
+configuration and the .gitmodules file in the worktree).
+
+For an example usage see test-submodule-config.c.

- *
- * RESOLVE_REF_ALLOW_BAD_NAME allows resolving refs even when their

- * is bad then the value stored in sha1 will be null_sha1 and the two

+Release 1.1.1 (bugfix-only release)
+===================================
+
+* The SMTP mailer was not working with Python 2.4.
+
+Release 1.1.0
+=============
+
+* When a single commit is pushed, omit the reference changed email.
+ Set multimailhook.combineWhenSingleCommit to false to disable this
+ new feature.
+
+* In gitolite environments, the pusher's email address can be used as
+ the From address by creating a specially formatted comment block in
+ gitolite.conf (see multimailhook.from in README).
+
+* Support for SMTP authentication and SSL/TLS encryption was added,
+ see smtpUser, smtpPass, smtpEncryption in README.
+
+* A new option scanCommitForCc was added to allow git-multimail to
+ search the commit message for 'Cc: ...' lines, and add the
+ corresponding emails in Cc.
+
+* If $USER is not set, use the variable $USERNAME. This is needed on
+ Windows platform to recognize the pusher.
+
+* The emailPrefix variable can now be set to an empty string to remove
+ the prefix.
+
+* A short tutorial was added in doc/gitolite.rst to set up
+ git-multimail with gitolite.
+
+* The post-receive file was renamed to post-receive.example. It has
+ always been an example (the standard way to call git-multimail is to
+ call git_multimail.py), but it was unclear to many users.
+
+* A new refchangeShowGraph option was added to make it possible to
+ include both a graph and a log in the summary emails. The options
+ to control the graph formatting can be set via the new graphOpts
+ option.
+
+* New option --force-send was added to disable new commit detection
+ for update hook. One use-case is to run git_multimail.py after
+ running "git fetch" to send emails about commits that have just been
+ fetched (the detection of new commits was unreliable in this mode).
+
+* The testing infrastructure was considerably improved (continuous
+ integration with travis-ci, automatic check of PEP8 and RST syntax,
+ many improvements to the test scripts).
+
+This version has been tested with Python 2.4 to 2.7, and Git 1.7.1 to
+2.4.
