+Git Release Notes
+=================
+
+Backward Compatibility Notes
+----------------------------
+
+ * "git branch -l <foo>" used to be a way to ask a reflog to be
+ created while creating a new branch, but that is no longer the
+ case. It is a short-hand for "git branch --list <foo>" now.
+
+ * "git push" into refs/tags/* hierarchy is rejected without getting
+ forced, but "git fetch" (misguidedly) used the "fast forwarding"
+ rule used for the refs/heads/* hierarchy; this has been corrected,
+ which means some fetches of tags that did not fail with older
+ version of Git will fail without "--force" with this version.
+
+ * "git help -a" now gives verbose output (same as "git help -av").
+ Those who want the old output may say "git help --no-verbose -a"..
+
+
+Updates since v2.19
+-------------------
+
+UI, Workflows & Features
+
+ * Running "git clone" against a project that contain two files with
+ pathnames that differ only in cases on a case insensitive
+ filesystem would result in one of the files lost because the
+ underlying filesystem is incapable of holding both at the same
+ time. An attempt is made to detect such a case and warn.
+
+ * "git checkout -b newbranch [HEAD]" should not have to do as much as
+ checking out a commit different from HEAD. An attempt is made to
+ optimize this special case.
+
+ * "git rev-list --stdin </dev/null" used to be an error; it now shows
+ no output without an error. "git rev-list --stdin --default HEAD"
+ still falls back to the given default when nothing is given on the
+ standard input.
+
+ * Lift code from GitHub to restrict delta computation so that an
+ object that exists in one fork is not made into a delta against
+ another object that does not appear in the same forked repository.
+
+ * "git format-patch" learned new "--interdiff" and "--range-diff"
+ options to explain the difference between this version and the
+ previous attempt in the cover letter (or after the tree-dashes as
+ a comment).
+
+ * "git mailinfo" used in "git am" learned to make a best-effort
+ recovery of a patch corrupted by MUA that sends text/plain with
+ format=flawed option.
+ (merge 3aa4d81f88 rs/mailinfo-format-flowed later to maint).
+
+ * The rules used by "git push" and "git fetch" to determine if a ref
+ can or cannot be updated were inconsistent; specifically, fetching
+ to update existing tags were allowed even though tags are supposed
+ to be unmoving anchoring points. "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 fo 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.
+
+
+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.
+
+
+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. Disable optimizations
+ based on its use (and updating existing commit-graph) when these
+ incompatible features are in use in the repository.
+ (merge 829a321569 ds/commit-graph-with-grafts later to maint).
+
+ * The mailmap file update.
+ (merge 255eb03edf jn/mailmap-update later to maint).
+
+ * The code in "git status" sometimes hit an assertion failure. This
+ was caused by a structure that was reused without cleaning the data
+ used for the first run, which has been corrected.
+ (merge 3e73cc62c0 en/status-multiple-renames-to-the-same-target-fix later to maint).
+
+ * "git fetch $repo $object" in a partial clone did not correctly
+ fetch the asked-for object that is referenced by an object in
+ promisor packfile, which has been fixed.
+
+ * A corner-case bugfix.
+ (merge c5cbb27cb5 sm/show-superproject-while-conflicted later to maint).
+
+ * Various fixes to "diff --color-moved-ws".
+
+ * A partial clone that is configured to lazily fetch missing objects
+ will on-demand issue a "git fetch" request to the originating
+ repository to fill not-yet-obtained objects. The request has been
+ optimized for requesting a tree object (and not the leaf blob
+ objects contained in it) by telling the originating repository that
+ no blobs are needed.
+ (merge 4c7f9567ea jt/non-blob-lazy-fetch later to maint).
+
+ * Code cleanup, docfix, build fix, etc.

-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

-
-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.

- avoid mistakes by always being explicit.
-
-* `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.
-
-* `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).
-
-* `tracking` - This is a deprecated synonym for `upstream`.
-
-* `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

- 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

-
-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>::

-
-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.

-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

- 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`.

+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.

+ Provides the default value for the `--from` option to format-patch.

+ The default for format-patch is to output a signature containing
+ the Git version number. Use this variable to change that default.

+ Works just like format.signature except the contents of the

+ The default pretty format for log/show/whatchanged command,

+ 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.

+ Set a custom directory to store the resulting files instead of the

+ below.
+
+
+DELTA ISLANDS
+-------------
+
+When possible, `pack-objects` tries to reuse existing on-disk deltas to
+avoid having to search for new ones on the fly. This is an important
+optimization for serving fetches, because it means the server can avoid
+inflating most objects at all and just send the bytes directly from
+disk. This optimization can't work when an object is stored as a delta
+against a base which the receiver does not have (and which we are not
+already sending). In that case the server "breaks" the delta and has to
+find a new one, which has a high CPU cost. Therefore it's important for
+performance that the set of objects in on-disk delta relationships match
+what a client would fetch.
+
+In a normal repository, this tends to work automatically. The objects
+are mostly reachable from the branches and tags, and that's what clients
+fetch. Any deltas we find on the server are likely to be between objects
+the client has or will have.
+
+But in some repository setups, you may have several related but separate
+groups of ref tips, with clients tending to fetch those groups
+independently. For example, imagine that you are hosting several "forks"
+of a repository in a single shared object store, and letting clients
+view them as separate repositories through `GIT_NAMESPACE` or separate
+repos using the alternates mechanism. A naive repack may find that the
+optimal delta for an object is against a base that is only found in
+another fork. But when a client fetches, they will not have the base
+object, and we'll have to find a new delta on the fly.
+
+A similar situation may exist if you have many refs outside of
+`refs/heads/` and `refs/tags/` that point to related objects (e.g.,
+`refs/pull` or `refs/changes` used by some hosting providers). By
+default, clients fetch only heads and tags, and deltas against objects
+found only in those other groups cannot be sent as-is.
+
+Delta islands solve this problem by allowing you to group your refs into
+distinct "islands". Pack-objects computes which objects are reachable
+from which islands, and refuses to make a delta from an object `A`
+against a base which is not present in all of `A`'s islands. This
+results in slightly larger packs (because we miss some delta
+opportunities), but guarantees that a fetch of one island will not have
+to recompute deltas on the fly due to crossing island boundaries.
+
+When repacking with delta islands the delta window tends to get
+clogged with candidates that are forbidden by the config. Repacking
+with a big --window helps (and doesn't take as long as it otherwise
+might because we can reject some object pairs based on islands before
+doing any computation on the content).
+
+Islands are configured via the `pack.island` option, which can be
+specified multiple times. Each value is a left-anchored regular
+expressions matching refnames. For example:
+
+-------------------------------------------
+[pack]
+island = refs/heads/
+island = refs/tags/
+-------------------------------------------
+
+puts heads and tags into an island (whose name is the empty string; see
+below for more on naming). Any refs which do not match those regular
+expressions (e.g., `refs/pull/123`) is not in any island. Any object
+which is reachable only from `refs/pull/` (but not heads or tags) is
+therefore not a candidate to be used as a base for `refs/heads/`.
+
+Refs are grouped into islands based on their "names", and two regexes
+that produce the same name are considered to be in the same
+island. The names are computed from the regexes by concatenating any
+capture groups from the regex, with a '-' dash in between. (And if
+there are no capture groups, then the name is the empty string, as in
+the above example.) This allows you to create arbitrary numbers of
+islands. Only up to 14 such capture groups are supported though.
+
+For example, imagine you store the refs for each fork in
+`refs/virtual/ID`, where `ID` is a numeric identifier. You might then
+configure:
+
+-------------------------------------------
+[pack]
+island = refs/virtual/([0-9]+)/heads/
+island = refs/virtual/([0-9]+)/tags/
+island = refs/virtual/([0-9]+)/(pull)/
+-------------------------------------------
+
+That puts the heads and tags for each fork in their own island (named
+"1234" or similar), and the pull refs for each go into their own
+"1234-pull".
+
+Note that we pick a single island for each regex to go into, using "last
+one wins" ordering (which allows repo-specific config to take precedence
+over user-wide config, and so forth).

+on the remote side. Whether this is allowed depends on where in
+`refs/*` the <dst> reference lives as described in detail below, in
+those sections "update" means any modifications except deletes, which
+as noted after the next few sections are treated differently.
++
+The `refs/heads/*` namespace will only accept commit objects, and
+updates only if they can be fast-forwarded.
++
+The `refs/tags/*` namespace will accept any kind of object (as
+commits, trees and blobs can be tagged), and any updates to them will
+be rejected.
++
+It's possible to push any type of object to any namespace outside of
+`refs/{tags,heads}/*`. In the case of tags and commits, these will be
+treated as if they were the commits inside `refs/heads/*` for the
+purposes of whether the update is allowed.
++
+I.e. a fast-forward of commits and tags outside `refs/{tags,heads}/*`
+is allowed, even in cases where what's being fast-forwarded is not a
+commit, but a tag object which happens to point to a new commit which
+is a fast-forward of the commit the last tag (or commit) it's
+replacing. Replacing a tag with an entirely different tag is also
+allowed, if it points to the same commit, as well as pushing a peeled
+tag, i.e. pushing the commit that existing tag object points to, or a
+new tag object which an existing commit points to.
++
+Tree and blob objects outside of `refs/{tags,heads}/*` will be treated
+the same way as if they were inside `refs/tags/*`, any update of them
+will be rejected.
++
+All of the rules described above about what's not allowed as an update
+can be overridden by adding an the optional leading `+` to a refspec
+(or using `--force` command line option). The only exception to this
+is that no amount of forcing will make the `refs/heads/*` namespace
+accept a non-commit object. Hooks and configuration can also override
+or amend these rules, see e.g. `receive.denyNonFastForwards` in
+linkgit:git-config[1] and `pre-receive` and `update` in
+linkgit:githooks[5].
++
+Pushing an empty <src> allows you to delete the <dst> ref from the
+remote repository. Deletions are always accepted without a leading `+`
+in the refspec (or `--force`), except when forbidden by configuration
+or hooks. See `receive.denyDeletes` in linkgit:git-config[1] and
+`pre-receive` and `update` in linkgit:githooks[5].

The special refspec `:` (or `+:` to allow non-fast-forward updates)

+section of linkgit:git-push[1] for what those are. Exceptions to those

+a commit for another commit that's doesn't have the previous commit as
+an ancestor etc.
++
+Unlike when pushing with linkgit:git-push[1], there is no
+configuration which'll amend these rules, and nothing like a

++
+As with pushing with linkgit:git-push[1], all of the rules described
+above about what's not allowed as an update can be overridden by
+adding an the optional leading `+` to a refspec (or using `--force`

+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:
++
+--
+
+* `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.
+
+* `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.
+
+* `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).
+
+* `tracking` - This is a deprecated synonym for `upstream`.
+
+* `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'.

+ By default, git-receive-pack will run "git-gc --auto" after

+ 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.

+Multi-Pack-Index (MIDX) Design Notes
+====================================
+
+The Git object directory contains a 'pack' directory containing
+packfiles (with suffix ".pack") and pack-indexes (with suffix
+".idx"). The pack-indexes provide a way to lookup objects and
+navigate to their offset within the pack, but these must come
+in pairs with the packfiles. This pairing depends on the file
+names, as the pack-index differs only in suffix with its pack-
+file. While the pack-indexes provide fast lookup per packfile,
+this performance degrades as the number of packfiles increases,
+because abbreviations need to inspect every packfile and we are
+more likely to have a miss on our most-recently-used packfile.
+For some large repositories, repacking into a single packfile
+is not feasible due to storage space or excessive repack times.
+
+The multi-pack-index (MIDX for short) stores a list of objects
+and their offsets into multiple packfiles. It contains:
+
+- A list of packfile names.
+- A sorted list of object IDs.
+- A list of metadata for the ith object ID including:
+ - A value j referring to the jth packfile.
+ - An offset within the jth packfile for the object.
+- If large offsets are required, we use another list of large
+ offsets similar to version 2 pack-indexes.
+
+Thus, we can provide O(log N) lookup time for any number
+of packfiles.
+
+Design Details
+--------------
+
+- The MIDX is stored in a file named 'multi-pack-index' in the
+ .git/objects/pack directory. This could be stored in the pack
+ directory of an alternate. It refers only to packfiles in that
+ same directory.
+
+- The pack.multiIndex config setting must be on to consume MIDX files.
+
+- The file format includes parameters for the object ID hash
+ function, so a future change of hash algorithm does not require
+ a change in format.
+
+- The MIDX keeps only one record per object ID. If an object appears
+ in multiple packfiles, then the MIDX selects the copy in the most-
+ recently modified packfile.
+
+- If there exist packfiles in the pack directory not registered in
+ the MIDX, then those packfiles are loaded into the `packed_git`
+ list and `packed_git_mru` cache.
+
+- The pack-indexes (.idx files) remain in the pack directory so we
+ can delete the MIDX file, set core.midx to false, or downgrade
+ without any loss of information.
+
+- The MIDX file format uses a chunk-based approach (similar to the
+ commit-graph file) that allows optional data to be added.
+
+Future Work
+-----------
+
+- Add a 'verify' subcommand to the 'git midx' builtin to verify the
+ contents of the multi-pack-index file match the offsets listed in
+ the corresponding pack-indexes.
+
+- The multi-pack-index allows many packfiles, especially in a context
+ where repacking is expensive (such as a very large repo), or
+ unexpected maintenance time is unacceptable (such as a high-demand
+ build machine). However, the multi-pack-index needs to be rewritten
+ in full every time. We can extend the format to be incremental, so
+ writes are fast. By storing a small "tip" multi-pack-index that
+ points to large "base" MIDX files, we can keep writes fast while
+ still reducing the number of binary searches required for object
+ lookups.
+
+- The reachability bitmap is currently paired directly with a single
+ packfile, using the pack-order as the object order to hopefully
+ compress the bitmaps well using run-length encoding. This could be
+ extended to pair a reachability bitmap with a multi-pack-index. If
+ the multi-pack-index is extended to store a "stable object order"
+ (a function Order(hash) = integer that is constant for a given hash,
+ even as the multi-pack-index is updated) then a reachability bitmap
+ could point to a multi-pack-index and be updated independently.
+
+- Packfiles can be marked as "special" using empty files that share
+ the initial name but replace ".pack" with ".keep" or ".promisor".
+ We can add an optional chunk of data to the multi-pack-index that
+ records flags of information about the packfiles. This allows new
+ states, such as 'repacked' or 'redeltified', that can help with
+ pack maintenance in a multi-pack environment. It may also be
+ helpful to organize packfiles by object type (commit, tree, blob,
+ etc.) and use this metadata to help that maintenance.
+
+- The partial clone feature records special "promisor" packs that
+ may point to objects that are not stored locally, but available
+ on request to a server. The multi-pack-index does not currently
+ track these promisor packs.

+Rerere
+======
+
+This document describes the rerere logic.
+
+Conflict normalization
+----------------------
+
+To ensure recorded conflict resolutions can be looked up in the rerere
+database, even when branches are merged in a different order,
+different branches are merged that result in the same conflict, or
+when different conflict style settings are used, rerere normalizes the
+conflicts before writing them to the rerere database.
+
+Different conflict styles and branch names are normalized by stripping
+the labels from the conflict markers, and removing the common ancestor
+version from the `diff3` conflict style. Branches that are merged
+in different order are normalized by sorting the conflict hunks. More
+on each of those steps in the following sections.
+
+Once these two normalization operations are applied, a conflict ID is
+calculated based on the normalized conflict, which is later used by
+rerere to look up the conflict in the rerere database.
+
+Removing the common ancestor version
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Say we have three branches AB, AC and AC2. The common ancestor of
+these branches has a file with a line containing the string "A" (for
+brevity this is called "line A" in the rest of the document). In
+branch AB this line is changed to "B", in AC, this line is changed to
+"C", and branch AC2 is forked off of AC, after the line was changed to
+"C".
+
+Forking a branch ABAC off of branch AB and then merging AC into it, we
+get a conflict like the following:
+
+ <<<<<<< HEAD
+ B
+ =======
+ C
+ >>>>>>> AC
+
+Doing the analogous with AC2 (forking a branch ABAC2 off of branch AB
+and then merging branch AC2 into it), using the diff3 conflict style,
+we get a conflict like the following:
+
+ <<<<<<< HEAD
+ B
+ ||||||| merged common ancestors
+ A
+ =======
+ C
+ >>>>>>> AC2
+
+By resolving this conflict, to leave line D, the user declares:
+
+ After examining what branches AB and AC did, I believe that making
+ line A into line D is the best thing to do that is compatible with
+ what AB and AC wanted to do.
+
+As branch AC2 refers to the same commit as AC, the above implies that
+this is also compatible what AB and AC2 wanted to do.
+
+By extension, this means that rerere should recognize that the above
+conflicts are the same. To do this, the labels on the conflict
+markers are stripped, and the common ancestor version is removed. The above
+examples would both result in the following normalized conflict:
+
+ <<<<<<<
+ B
+ =======
+ C
+ >>>>>>>
+
+Sorting hunks
+~~~~~~~~~~~~~
+
+As before, lets imagine that a common ancestor had a file with line A
+its early part, and line X in its late part. And then four branches
+are forked that do these things:
+
+ - AB: changes A to B
+ - AC: changes A to C
+ - XY: changes X to Y
+ - XZ: changes X to Z
+
+Now, forking a branch ABAC off of branch AB and then merging AC into
+it, and forking a branch ACAB off of branch AC and then merging AB
+into it, would yield the conflict in a different order. The former
+would say "A became B or C, what now?" while the latter would say "A
+became C or B, what now?"
+
+As a reminder, the act of merging AC into ABAC and resolving the
+conflict to leave line D means that the user declares:
+
+ After examining what branches AB and AC did, I believe that
+ making line A into line D is the best thing to do that is
+ compatible with what AB and AC wanted to do.
+
+So the conflict we would see when merging AB into ACAB should be
+resolved the same way---it is the resolution that is in line with that
+declaration.
+
+Imagine that similarly previously a branch XYXZ was forked from XY,
+and XZ was merged into it, and resolved "X became Y or Z" into "X
+became W".
+
+Now, if a branch ABXY was forked from AB and then merged XY, then ABXY
+would have line B in its early part and line Y in its later part.
+Such a merge would be quite clean. We can construct 4 combinations
+using these four branches ((AB, AC) x (XY, XZ)).
+
+Merging ABXY and ACXZ would make "an early A became B or C, a late X
+became Y or Z" conflict, while merging ACXY and ABXZ would make "an
+early A became C or B, a late X became Y or Z". We can see there are
+4 combinations of ("B or C", "C or B") x ("X or Y", "Y or X").
+
+By sorting, the conflict is given its canonical name, namely, "an
+early part became B or C, a late part becames X or Y", and whenever
+any of these four patterns appear, and we can get to the same conflict
+and resolution that we saw earlier.
+
+Without the sorting, we'd have to somehow find a previous resolution
+from combinatorial explosion.
+
+Conflict ID calculation
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Once the conflict normalization is done, the conflict ID is calculated
+as the sha1 hash of the conflict hunks appended to each other,
+separated by <NUL> characters. The conflict markers are stripped out
+before the sha1 is calculated. So in the example above, where we
+merge branch AC which changes line A to line C, into branch AB, which
+changes line A to line C, the conflict ID would be
+SHA1('B<NUL>C<NUL>').
+
+If there are multiple conflicts in one file, the sha1 is calculated
+the same way with all hunks appended to each other, in the order in
+which they appear in the file, separated by a <NUL> character.
+
+Nested conflicts
+~~~~~~~~~~~~~~~~
+
+Nested conflicts are handled very similarly to "simple" conflicts.
+Similar to simple conflicts, the conflict is first normalized by
+stripping the labels from conflict markers, stripping the common ancestor
+version, and the sorting the conflict hunks, both for the outer and the
+inner conflict. This is done recursively, so any number of nested
+conflicts can be handled.
+
+Note that this only works for conflict markers that "cleanly nest". If
+there are any unmatched conflict markers, rerere will fail to handle
+the conflict and record a conflict resolution.
+
+The only difference is in how the conflict ID is calculated. For the
+inner conflict, the conflict markers themselves are not stripped out
+before calculating the sha1.
+
+Say we have the following conflict for example:
+
+ <<<<<<< HEAD
+ 1
+ =======
+ <<<<<<< HEAD
+ 3
+ =======
+ 2
+ >>>>>>> branch-2
+ >>>>>>> branch-3~
+
+After stripping out the labels of the conflict markers, and sorting
+the hunks, the conflict would look as follows:
+
+ <<<<<<<
+ 1
+ =======
+ <<<<<<<
+ 2
+ =======
+ 3
+ >>>>>>>
+ >>>>>>>
+
+and finally the conflict ID would be calculated as:
+`sha1('1<NUL><<<<<<<\n3\n=======\n2\n>>>>>>><NUL>')`
