+Git 2.13 Release Notes
+======================
+
+Backward compatibility notes.
+
+ * Use of an empty string as a pathspec element that is used for
+ 'everything matches' is still warned and Git asks users to use a
+ more explicit '.' for that instead. The hope is that existing
+ users will not mind this change, and eventually the warning can be
+ turned into a hard error, upgrading the deprecation into removal of
+ this (mis)feature. That is not scheduled to happen in the upcoming
+ release (yet).
+
+ * The historical argument order "git merge <msg> HEAD <commit>..."
+ has been deprecated for quite some time, and is now removed.
+
+ * The default location "~/.git-credential-cache/socket" for the
+ socket used to communicate with the credential-cache daemon has
+ been moved to "~/.cache/git/credential/socket".
+
+ * Git now avoids blindly falling back to ".git" when the setup
+ sequence said we are _not_ in Git repository. A corner case that
+ happens to work right now may be broken by a call to die("BUG").
+ We've tried hard to locate such cases and fixed them, but there
+ might still be cases that need to be addressed--bug reports are
+ greatly appreciated.
+
+
+Updates since v2.12
+-------------------
+
+UI, Workflows & Features
+
+ * "git describe" and "git name-rev" have been taught to take more
+ than one refname patterns to restrict the set of refs to base their
+ naming output on, and also learned to take negative patterns to
+ name refs not to be used for naming via their "--exclude" option.
+
+ * Deletion of a branch "foo/bar" could remove .git/refs/heads/foo
+ once there no longer is any other branch whose name begins with
+ "foo/", but we didn't do so so far. Now we do.
+
+ * When "git merge" detects a path that is renamed in one history
+ while the other history deleted (or modified) it, it now reports
+ both paths to help the user understand what is going on in the two
+ histories being merged.
+
+ * The <url> part in "http.<url>.<variable>" configuration variable
+ can now be spelled with '*' that serves as wildcard.
+ E.g. "http.https://*.example.com.proxy" can be used to specify the
+ proxy used for https://a.example.com, https://b.example.com, etc.,
+ i.e. any host in the example.com domain.
+
+ * "git tag" did not leave useful message when adding a new entry to
+ reflog; this was left unnoticed for a long time because refs/tags/*
+ doesn't keep reflog by default.
+
+ * The "negative" pathspec feature was somewhat more cumbersome to use
+ than necessary in that its short-hand used "!" which needed to be
+ escaped from shells, and it required "exclude from what?" specified.
+
+ * The command line options for ssh invocation needs to be tweaked for
+ some implementations of SSH (e.g. PuTTY plink wants "-P <port>"
+ while OpenSSH wants "-p <port>" to specify port to connect to), and
+ the variant was guessed when GIT_SSH environment variable is used
+ to specify it. The logic to guess now applies to the command
+ specified by the newer GIT_SSH_COMMAND and also core.sshcommand
+ configuration variable, and comes with an escape hatch for users to
+ deal with misdetected cases.
+
+ * The "--git-path", "--git-common-dir", and "--shared-index-path"
+ options of "git rev-parse" did not produce usable output. They are
+ now updated to show the path to the correct file, relative to where
+ the caller is.
+
+ * "git diff -W" has been taught to handle the case where a new
+ function is added at the end of the file better.
+
+ * "git update-ref -d" and other operations to delete references did
+ not leave any entry in HEAD's reflog when the reference being
+ deleted was the current branch. This is not a problem in practice
+ because you do not want to delete the branch you are currently on,
+ but caused renaming of the current branch to something else not to
+ be logged in a useful way.
+
+ * "Cc:" on the trailer part does not have to conform to RFC strictly,
+ unlike in the e-mail header. "git send-email" has been updated to
+ ignore anything after '>' when picking addresses, to allow non-address
+ cruft like " # stable 4.4" after the address.
+
+ * When "git submodule init" decides that the submodule in the working
+ tree is its upstream, it now gives a warning as it is not a very
+ common setup.
+
+ * "git stash push" takes a pathspec so that the local changes can be
+ stashed away only partially.
+
+ * Documentation for "git ls-files" did not refer to core.quotePath.
+
+ * The experimental "split index" feature has gained a few
+ configuration variables to make it easier to use.
+
+ * From a working tree of a repository, a new option of "rev-parse"
+ lets you ask if the repository is used as a submodule of another
+ project, and where the root level of the working tree of that
+ project (i.e. your superproject) is.
+
+ * The pathspec mechanism learned to further limit the paths that
+ match the pattern to those that have specified attributes attached
+ via the gitattributes mechanism.
+
+ * Our source code has used the SHA1_HEADER cpp macro after "#include"
+ in the C code to switch among the SHA-1 implementations. Instead,
+ list the exact header file names and switch among implementations
+ using "#ifdef BLK_SHA1/#include "block-sha1/sha1.h"/.../#endif";
+ this helps some IDE tools.
+
+ * The start-up sequence of "git" needs to figure out some configured
+ settings before it finds and set itself up in the location of the
+ repository and was quite messy due to its "chicken-and-egg" nature.
+ The code has been restructured.
+
+ * The command line prompt (in contrib/) learned a new 'tag' style
+ that can be specified with GIT_PS1_DESCRIBE_STYLE, to describe a
+ detached HEAD with "git describe --tags".
+
+ * The configuration file learned a new "includeIf.<condition>.path"
+ that includes the contents of the given path only when the
+ condition holds. This allows you to say "include this work-related
+ bit only in the repositories under my ~/work/ directory".
+
+ * Recent update to "rebase -i" started showing a message that is not
+ a warning with "warning:" prefix by mistake. This has been fixed.
+
+ * Recently we started passing the "--push-options" through the
+ external remote helper interface; now the "smart HTTP" remote
+ helper understands what to do with the passed information.
+
+ * "git describe --dirty" dies when it cannot be determined if the
+ state in the working tree matches that of HEAD (e.g. broken
+ repository or broken submodule). The command learned a new option
+ "git describe --broken" to give "$name-broken" (where $name is the
+ description of HEAD) in such a case.
+
+ * "git checkout" is taught the "--recurse-submodules" option.
+
+ * Recent enhancement to "git stash push" command to support pathspec
+ to allow only a subset of working tree changes to be stashed away
+ was found to be too chatty and exposed the internal implementation
+ detail (e.g. when it uses reset to match the index to HEAD before
+ doing other things, output from reset seeped out). These, and
+ other chattyness has been fixed.
+
+ * "git merge <message> HEAD <commit>" syntax that has been deprecated
+ since October 2007 has been removed.
+
+ * The refs completion for large number of refs has been sped up,
+ partly by giving up disambiguating ambiguous refs and partly by
+ eliminating most of the shell processing between 'git for-each-ref'
+ and 'ls-remote' and Bash's completion facility.
+
+ * On many keyboards, typing "@{" involves holding down SHIFT key and
+ one can easily end up with "@{Up..." when typing "@{upstream}". As
+ the upstream/push keywords do not appear anywhere else in the syntax,
+ we can safely accept them case insensitively without introducing
+ ambiguity or confusion to solve this.
+
+ * "git tag/branch/for-each-ref" family of commands long allowed to
+ filter the refs by "--contains X" (show only the refs that are
+ descendants of X), "--merged X" (show only the refs that are
+ ancestors of X), "--no-merged X" (show only the refs that are not
+ ancestors of X). One curious omission, "--no-contains X" (show
+ only the refs that are not descendants of X) has been added to
+ them.
+
+ * The default behaviour of "git log" in an interactive session has
+ been changed to enable "--decorate".
+
+ * The output from "git status --short" has been extended to show
+ various kinds of dirtyness in submodules differently; instead of to
+ "M" for modified, 'm' and '?' can be shown to signal changes only
+ to the working tree of the submodule but not the commit that is
+ checked out.
+
+ * Allow the http.postbuffer configuration variable to be set to a
+ size that can be expressed in size_t, which can be larger than
+ ulong on some platforms.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * The code to list branches in "git branch" has been consolidated
+ with the more generic ref-filter API.
+
+ * Resource usage while enumerating refs from alternate object store
+ has been optimized to help receiving end of "push" that hosts a
+ repository with many "forks".
+
+ * The gitattributes machinery is being taught to work better in a
+ multi-threaded environment.
+
+ * "git rebase -i" starts using the recently updated "sequencer" code.
+
+ * Code and design clean-up for the refs API.
+
+ * The preload-index code has been taught not to bother with the index
+ entries that are paths that are not checked out by "sparse checkout".
+
+ * Some warning() messages from "git clean" were updated to show the
+ errno from failed system calls.
+
+ * The "parse_config_key()" API function has been cleaned up.
+
+ * A test that creates a confusing branch whose name is HEAD has been
+ corrected not to do so.
+
+ * The code that parses header fields in the commit object has been
+ updated for (micro)performance and code hygiene.
+
+ * An helper function to make it easier to append the result from
+ real_path() to a strbuf has been added.
+
+ * Reduce authentication round-trip over HTTP when the server supports
+ just a single authentication method. This also improves the
+ behaviour when Git is misconfigured to enable http.emptyAuth
+ against a server that does not authenticate without a username
+ (i.e. not using Kerberos etc., which makes http.emptyAuth
+ pointless).
+
+ * Windows port wants to use OpenSSL's implementation of SHA-1
+ routines, so let them.
+
+ * The t/perf performance test suite was not prepared to test not so
+ old versions of Git, but now it covers versions of Git that are not
+ so ancient.
+
+ * Add 32-bit Linux variant to the set of platforms to be tested with
+ Travis CI.
+
+ * "git branch --list" takes the "--abbrev" and "--no-abbrev" options
+ to control the output of the object name in its "-v"(erbose)
+ output, but a recent update started ignoring them; fix it before
+ the breakage reaches to any released version.
+
+ * Picking two versions of Git and running tests to make sure the
+ older one and the newer one interoperate happily has now become
+ possible.
+
+ * "git tag --contains" used to (ab)use the object bits to keep track
+ of the state of object reachability without clearing them after
+ use; this has been cleaned up and made to use the newer commit-slab
+ facility.
+
+ * The "debug" helper used in the test framework learned to run
+ a command under "gdb" interactively.
+
+ * The "detect attempt to create collisions" variant of SHA-1
+ implementation by Marc Stevens (CWI) and Dan Shumow (Microsoft)
+ has been integrated and made the default.
+
+ * The test framework learned to detect unterminated here documents.
+
+ * The name-hash used for detecting paths that are different only in
+ cases (which matter on case insensitive filesystems) has been
+ optimized to take advantage of multi-threading when it makes sense.
+
+ * An earlier version of sha1dc/sha1.c that was merged to 'master'
+ compiled incorrectly on Windows, which has been fixed.
+
+ * "what URL do we want to update this submodule?" and "are we
+ interested in this submodule?" are split into two distinct
+ concepts, and then the way used to express the latter got extended,
+ paving a way to make it easier to manage a project with many
+ submodules and make it possible to later extend use of multiple
+ worktrees for a project with submodules.
+
+ * Some debugging output from "git describe" were marked for l10n,
+ but some weren't. Mark missing ones for l10n.
+
+ * Define a new task in .travis.yml that triggers a test session on
+ Windows run elsewhere.
+
+ * Conversion from uchar[20] to struct object_id continues.
+
+ * The "submodule" specific field in the ref_store structure is
+ replaced with a more generic "gitdir" that can later be used also
+ when dealing with ref_store that represents the set of refs visible
+ from the other worktrees.
+
+ * The string-list API used a custom reallocation strategy that was
+ very inefficient, instead of using the usual ALLOC_GROW() macro,
+ which has been fixed.
+ (merge 950a234cbd jh/string-list-micro-optim later to maint).
+
+ * In a 2- and 3-way merge of trees, more than one source trees often
+ end up sharing an identical subtree; optimize by not reading the
+ same tree multiple times in such a case.
+ (merge d12a8cf0af jh/unpack-trees-micro-optim later to maint).
+
+ * The index file has a trailing SHA-1 checksum to detect file
+ corruption, and historically we checked it every time the index
+ file is used. Omit the validation during normal use, and instead
+ verify only in "git fsck".
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.12
+-----------------
+
+Unless otherwise noted, all the fixes since v2.12 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git repack --depth=<n>" for a long time busted the specified depth
+ when reusing delta from existing packs. This has been corrected.
+
+ * The code to parse the command line "git grep <patterns>... <rev>
+ [[--] <pathspec>...]" has been cleaned up, and a handful of bugs
+ have been fixed (e.g. we used to check "--" if it is a rev).
+
+ * "git ls-remote" and "git archive --remote" are designed to work
+ without being in a directory under Git's control. However, recent
+ updates revealed that we randomly look into a directory called
+ .git/ without actually doing necessary set-up when working in a
+ repository. Stop doing so.
+
+ * "git show-branch" expected there were only very short branch names
+ in the repository and used a fixed-length buffer to hold them
+ without checking for overflow.
+
+ * A caller of tempfile API that uses stdio interface to write to
+ files may ignore errors while writing, which is detected when
+ tempfile is closed (with a call to ferror()). By that time, the
+ original errno that may have told us what went wrong is likely to
+ be long gone and was overwritten by an irrelevant value.
+ close_tempfile() now resets errno to EIO to make errno at least
+ predictable.
+
+ * "git remote rm X", when a branch has remote X configured as the
+ value of its branch.*.remote, tried to remove branch.*.remote and
+ branch.*.merge and failed if either is unset.
+
+ * A "gc.log" file left by a backgrounded "gc --auto" disables further
+ automatic gc; it has been taught to run at least once a day (by
+ default) by ignoring a stale "gc.log" file that is too old.
+
+ * The code to parse "git -c VAR=VAL cmd" and set configuration
+ variable for the duration of cmd had two small bugs, which have
+ been fixed.
+
+ * user.email that consists of only cruft chars should consistently
+ error out, but didn't.
+
+ * "git upload-pack", which is a counter-part of "git fetch", did not
+ report a request for a ref that was not advertised as invalid.
+ This is generally not a problem (because "git fetch" will stop
+ before making such a request), but is the right thing to do.
+
+ * A leak in a codepath to read from a packed object in (rare) cases
+ has been plugged.
+
+ * When a redirected http transport gets an error during the
+ redirected request, we ignored the error we got from the server,
+ and ended up giving a not-so-useful error message.
+
+ * The patch subcommand of "git add -i" was meant to have paths
+ selection prompt just like other subcommand, unlike "git add -p"
+ directly jumps to hunk selection. Recently, this was broken and
+ "add -i" lost the paths selection dialog, but it now has been
+ fixed.
+
+ * Git v2.12 was shipped with an embarrassing breakage where various
+ operations that verify paths given from the user stopped dying when
+ seeing an issue, and instead later triggering segfault.
+
+ * There is no need for Python only to give a few messages to the
+ standard error stream, but we somehow did.
+
+ * The code to parse "git log -L..." command line was buggy when there
+ are many ranges specified with -L; overrun of the allocated buffer
+ has been fixed.
+
+ * The command-line parsing of "git log -L" copied internal data
+ structures using incorrect size on ILP32 systems.
+
+ * "git diff --quiet" relies on the size field in diff_filespec to be
+ correctly populated, but diff_populate_filespec() helper function
+ made an incorrect short-cut when asked only to populate the size
+ field for paths that need to go through convert_to_git() (e.g. CRLF
+ conversion).
+
+ * A few tests were run conditionally under (rare) conditions where
+ they cannot be run (like running cvs tests under 'root' account).
+
+ * "git branch @" created refs/heads/@ as a branch, and in general the
+ code that handled @{-1} and @{upstream} was a bit too loose in
+ disambiguating.
+
+ * "git fetch" that requests a commit by object name, when the other
+ side does not allow such an request, failed without much
+ explanation.
+
+ * "git filter-branch --prune-empty" drops a single-parent commit that
+ becomes a no-op, but did not drop a root commit whose tree is empty.
+
+ * Recent versions of Git treats http alternates (used in dumb http
+ transport) just like HTTP redirects and requires the client to
+ enable following it, due to security concerns. But we forgot to
+ give a warning when we decide not to honor the alternates.
+
+ * "git push" had a handful of codepaths that could lead to a deadlock
+ when unexpected error happened, which has been fixed.
+
+ * "Dumb http" transport used to misparse a nonsense http-alternates
+ response, which has been fixed.
+
+ * "git add -p <pathspec>" unnecessarily expanded the pathspec to a
+ list of individual files that matches the pathspec by running "git
+ ls-files <pathspec>", before feeding it to "git diff-index" to see
+ which paths have changes, because historically the pathspec
+ language supported by "diff-index" was weaker. These days they are
+ equivalent and there is no reason to internally expand it. This
+ helps both performance and avoids command line argument limit on
+ some platforms.
+ (merge 7288e12cce jk/add-i-use-pathspecs later to maint).
+
+ * "git status --porcelain" is supposed to give a stable output, but a
+ few strings were left as translatable by mistake.
+
+ * "git revert -m 0 $merge_commit" complained that reverting a merge
+ needs to say relative to which parent the reversion needs to
+ happen, as if "-m 0" weren't given. The correct diagnosis is that
+ "-m 0" does not refer to the first parent ("-m 1" does). This has
+ been fixed.
+
+ * Code to read submodule.<name>.ignore config did not state the
+ variable name correctly when giving an error message diagnosing
+ misconfiguration.
+
+ * Fix for NO_PTHREADS build.
+
+ * Fix for potential segv introduced in v2.11.0 and later (also
+ v2.10.2) to "git log --pickaxe-regex -S".
+
+ * A few unterminated here documents in tests were fixed, which in
+ turn revealed incorrect expectations the tests make. These tests
+ have been updated.
+
+ * Fix for NO_PTHREADS option.
+ (merge 2225e1ea20 bw/grep-recurse-submodules later to maint).
+
+ * Git now avoids blindly falling back to ".git" when the setup
+ sequence said we are _not_ in Git repository. A corner case that
+ happens to work right now may be broken by a call to die("BUG").
+ (merge b1ef400eec jk/no-looking-at-dotgit-outside-repo-final later to maint).
+
+ * A few commands that recently learned the "--recurse-submodule"
+ option misbehaved when started from a subdirectory of the
+ superproject.
+ (merge b2dfeb7c00 bw/recurse-submodules-relative-fix later to maint).
+
+ * FreeBSD implementation of getcwd(3) behaved differently when an
+ intermediate directory is unreadable/unsearchable depending on the
+ length of the buffer provided, which our strbuf_getcwd() was not
+ aware of. strbuf_getcwd() has been taught to cope with it better.
+ (merge a54e938e5b rs/freebsd-getcwd-workaround later to maint).
+
+ * A recent update to "rebase -i" stopped running hooks for the "git
+ commit" command during "reword" action, which has been fixed.
+
+ * Removing an entry from a notes tree and then looking another note
+ entry from the resulting tree using the internal notes API
+ functions did not work as expected. No in-tree users of the API
+ has such access pattern, but it still is worth fixing.
+
+ * "git receive-pack" could have been forced to die by attempting
+ allocate an unreasonably large amount of memory with a crafted push
+ certificate; this has been fixed.
+ (merge f2214dede9 bc/push-cert-receive-fix later to maint).
+
+ * Update error handling for codepath that deals with corrupt loose
+ objects.
+ (merge 51054177b3 jk/loose-object-info-report-error later to maint).
+
+ * "git diff --submodule=diff" learned to work better in a project
+ with a submodule that in turn has its own submodules.
+ (merge 17b254cda6 sb/show-diff-for-submodule-in-diff-fix later to maint).
+
+ * Update the build dependency so that an update to /usr/bin/perl
+ etc. result in recomputation of perl.mak file.
+ (merge c59c4939c2 ab/regen-perl-mak-with-different-perl later to maint).
+
+ * "git push --recurse-submodules --push-option=<string>" learned to
+ propagate the push option recursively down to pushes in submodules.
+
+ * If a patch e-mail had its first paragraph after an in-body header
+ indented (even after a blank line after the in-body header line),
+ the indented line was mistook as a continuation of the in-body
+ header. This has been fixed.
+ (merge fd1062e52e lt/mailinfo-in-body-header-continuation later to maint).
+
+ * Clean up fallouts from recent tightening of the set-up sequence,
+ where Git barfs when repository information is accessed without
+ first ensuring that it was started in a repository.
+ (merge bccb22cbb1 jk/no-looking-at-dotgit-outside-repo later to maint).
+
+ * "git p4" used "name-rev HEAD" when it wants to learn what branch is
+ checked out; it should use "symbolic-ref HEAD".
+ (merge eff451101d ld/p4-current-branch-fix later to maint).
+
+ * "http.proxy" set to an empty string is used to disable the usage of
+ proxy. We broke this early last year.
+ (merge ae51d91105 sr/http-proxy-configuration-fix later to maint).
+
+ * $GIT_DIR may in some cases be normalized with all symlinks resolved
+ while "gitdir" path expansion in the pattern does not receive the
+ same treatment, leading to incorrect mismatch. This has been fixed.
+
+ * "git submodule" script does not work well with strange pathnames.
+ Protect it from a path with slashes in them, at least.
+
+ * "git fetch-pack" was not prepared to accept ERR packet that the
+ upload-pack can send with a human-readable error message. It
+ showed the packet contents with ERR prefix, so there was no data
+ loss, but it was redundant to say "ERR" in an error message.
+ (merge 8e2c7bef03 jt/fetch-pack-error-reporting later to maint).
+
+ * "ls-files --recurse-submodules" did not quite work well in a
+ project with nested submodules.
+
+ * gethostname(2) may not NUL terminate the buffer if hostname does
+ not fit; unfortunately there is no easy way to see if our buffer
+ was too small, but at least this will make sure we will not end up
+ using garbage past the end of the buffer.
+ (merge 5781a9a270 dt/xgethostname-nul-termination later to maint).
+

+`include.path` variable is a relative path, the path is considered to
+be relative to the configuration file in which the include directive

+Conditional includes
+~~~~~~~~~~~~~~~~~~~~
+
+You can include a config file from another conditionally by setting a
+`includeIf.<condition>.path` variable to the name of the file to be
+included. The variable's value is treated the same way as
+`include.path`. `includeIf.<condition>.path` can be given multiple times.
+
+The condition starts with a keyword followed by a colon and some data
+whose format and meaning depends on the keyword. Supported keywords
+are:
+
+`gitdir`::
+
+ The data that follows the keyword `gitdir:` is used as a glob
+ pattern. If the location of the .git directory matches the
+ pattern, the include condition is met.
++
+The .git location may be auto-discovered, or come from `$GIT_DIR`
+environment variable. If the repository is auto discovered via a .git
+file (e.g. from submodules, or a linked worktree), the .git location
+would be the final location where the .git directory is, not where the
+.git file is.
++
+The pattern can contain standard globbing wildcards and two additional
+ones, `**/` and `/**`, that can match multiple path components. Please
+refer to linkgit:gitignore[5] for details. For convenience:
+
+ * If the pattern starts with `~/`, `~` will be substituted with the
+ content of the environment variable `HOME`.
+
+ * If the pattern starts with `./`, it is replaced with the directory
+ containing the current config file.
+
+ * If the pattern does not start with either `~/`, `./` or `/`, `**/`
+ will be automatically prepended. For example, the pattern `foo/bar`
+ becomes `**/foo/bar` and would match `/any/path/to/foo/bar`.
+
+ * If the pattern ends with `/`, `**` will be automatically added. For
+ example, the pattern `foo/` becomes `foo/**`. In other words, it
+ matches "foo" and everything inside, recursively.
+
+`gitdir/i`::
+ This is the same as `gitdir` except that matching is done
+ case-insensitively (e.g. on case-insensitive file sytems)
+
+A few more notes on matching via `gitdir` and `gitdir/i`:
+
+ * Symlinks in `$GIT_DIR` are not resolved before matching.
+
+ * Note that "../" is not special and will match literally, which is
+ unlikely what you want.

path = ~/foo ; expand "foo" in your `$HOME` directory

+ shared index is never written.
+ By default the value is 20, so a new shared index is written

+`strip` can be used as a synomym to `lstrip`.
objecttype::
The type of the object (`blob`, `tree`, `commit`, `tag`).

++
+A general note on safety: supplying this option without an expected
+value, i.e. as `--force-with-lease` or `--force-with-lease=<refname>`
+interacts very badly with anything that implicitly runs `git fetch` on
+the remote to be pushed to in the background, e.g. `git fetch origin`
+on your repository in a cronjob.
++
+The protection it offers over `--force` is ensuring that subsequent
+changes your work wasn't based on aren't clobbered, but this is
+trivially defeated if some background process is updating refs in the
+background. We don't have anything except the remote tracking info to
+go by as a heuristic for refs you're expected to have seen & are
+willing to clobber.
++
+If your editor or some other system is running `git fetch` in the
+background for you a way to mitigate this is to simply set up another
+remote:
++
+ git remote add origin-push $(git config remote.origin.url)
+ git fetch origin-push
++
+Now when the background process runs `git fetch origin` the references
+on `origin-push` won't be updated, and thus commands like:
++
+ git push --force-with-lease origin-push
++
+Will fail unless you manually run `git fetch origin-push`. This method
+is of course entirely defeated by something that runs `git fetch
+--all`, in that case you'd need to either disable it or do something
+more tedious like:
++
+ git fetch # update 'master' from remote
+ git tag base master # mark our base point
+ git rebase -i master # rewrite some commits
+ git push --force-with-lease=master:base master:master
++
+I.e. create a `base` tag for versions of the upstream code that you've
+seen and are willing to overwrite, then rewrite history, and finally
+force push changes to `master` if the remote version is still at
+`base`, regardless of what your local `remotes/origin/master` has been

+Quarantine Environment
+----------------------
+
+When `receive-pack` takes in objects, they are placed into a temporary
+"quarantine" directory within the `$GIT_DIR/objects` directory and
+migrated into the main object store only after the `pre-receive` hook
+has completed. If the push fails before then, the temporary directory is
+removed entirely.
+
+This has a few user-visible effects and caveats:
+
+ 1. Pushes which fail due to problems with the incoming pack, missing
+ objects, or due to the `pre-receive` hook will not leave any
+ on-disk data. This is usually helpful to prevent repeated failed
+ pushes from filling up your disk, but can make debugging more
+ challenging.
+
+ 2. Any objects created by the `pre-receive` hook will be created in
+ the quarantine directory (and migrated only if it succeeds).
+
+ 3. The `pre-receive` hook MUST NOT update any refs to point to
+ quarantined objects. Other programs accessing the repository will
+ not be able to see the objects (and if the pre-receive hook fails,
+ those refs would become corrupted). For safety, any ref updates
+ from within `pre-receive` are automatically rejected.

which is located right next to a superproject 'bar.git', you'll
have to use '../foo.git' instead of './foo.git' - as one might expect

of relative URLs in Git is identical to that of relative directories).

+Split index
+-----------
+
+This mode is designed for repositories with very large indexes, and
+aims at reducing the time it takes to repeatedly write these indexes.
+
+In this mode, the index is split into two files, $GIT_DIR/index and
+$GIT_DIR/sharedindex.<SHA-1>. Changes are accumulated in
+$GIT_DIR/index, the split index, while the shared index file contains
+all index entries and stays unchanged.
+
+All changes in the split index are pushed back to the shared index
+file when the number of entries in the split index reaches a level
+specified by the splitIndex.maxPercentChange config variable (see
+linkgit:git-config[1]).
+
+Each time a new shared index file is created, the old shared index
+files are deleted if their modification time is older than what is
+specified by the splitIndex.sharedIndexExpire config variable (see
+linkgit:git-config[1]).
+
+To avoid deleting a shared index file that is still used, its
+modification time is updated to the current time everytime a new split
+index based on the shared index file is either created or read from.

Attribute Values
An attribute for a path can be in one of four states: Set, Unset,
Unspecified or set to a string, and `.value` member of `struct

`ATTR_TRUE()`::
Querying Specific Attributes
----------------------------
-* Prepare an array of `struct git_attr_check` to define the list of
- attributes you would want to check. To populate this array, you would
- need to define necessary attributes by calling `git_attr()` function.
+* Prepare `struct attr_check` using attr_check_initl()
+ function, enumerating the names of attributes whose values you are
+ interested in, terminated with a NULL pointer. Alternatively, an
+ empty `struct attr_check` can be prepared by calling
+ `attr_check_alloc()` function and then attributes you want to
+ ask about can be added to it with `attr_check_append()`
+ function.
* Call `git_check_attr()` to check the attributes for the path.
-* Inspect `git_attr_check` structure to see how each of the attribute in
- the array is defined for the path.
+* Inspect `attr_check` structure to see how each of the
+ attribute in the array is defined for the path.
Example
-------
-To see how attributes "crlf" and "indent" are set for different paths.
+To see how attributes "crlf" and "ident" are set for different paths.
-. Prepare an array of `struct git_attr_check` with two elements (because
- we are checking two attributes). Initialize their `attr` member with
- pointers to `struct git_attr` obtained by calling `git_attr()`:

return; /* already done */

- check[1].attr = git_attr("ident");

+ attr_check_append(check, attr);
+ argv++;
+ }
+}
+------------
+
Querying All Attributes
-----------------------
To get the values of all attributes associated with a file:
-* Call `git_all_attrs()`, which returns an array of `git_attr_check`
- structures.
+* Prepare an empty `attr_check` structure by calling
+ `attr_check_alloc()`.
+
+* Call `git_all_attrs()`, which populates the `attr_check`
+ with the attributes attached to the path.
-* Iterate over the `git_attr_check` array to examine the attribute
- names and values. The name of the attribute described by a
- `git_attr_check` object can be retrieved via
- `git_attr_name(check[i].attr)`. (Please note that no items will be
- returned for unset attributes, so `ATTR_UNSET()` will return false
- for all returned `git_array_check` objects.)
+* Iterate over the `attr_check.items[]` array to examine
+ the attribute names and values. The name of the attribute
+ described by a `attr_check.items[]` object can be retrieved via
+ `git_attr_name(check->items[i].attr)`. (Please note that no items
+ will be returned for unset attributes, so `ATTR_UNSET()` will return
+ false for all returned `attr_check.items[]` objects.)
-* Free the `git_array_check` array.
+* Free the `attr_check` struct by calling `attr_check_free()`.
`cmpfn` stores the comparison function specified in `hashmap_init()`. In
advanced scenarios, it may be useful to change this, e.g. to switch between
case-sensitive and case-insensitive lookup.
++
+When `disallow_rehash` is set, automatic rehashes are prevented during inserts
+and deletes.

`unsigned int strihash(const char *buf)`::
`unsigned int memhash(const void *buf, size_t len)`::

Ready-to-use hash functions for strings, using the FNV-1 algorithm (see
http://www.isthe.com/chongo/tech/comp/fnv).
`memihash` operate on arbitrary-length memory.
+
`strihash` and `memihash` are case insensitive versions.
++
+`memihash_cont` is a variant of `memihash` that allows a computation to be
+continued with another chunk of data.

++
+This is useful if the caller knows that the hashmap will be accessed
+by multiple threads.
++
+The caller is still responsible for any necessary locking; this simply
+prevents unexpected rehashing. The caller is also responsible for properly
+sizing the initial hashmap to ensure good performance.

+oid-array API
+==============
+
+The oid-array API provides storage and manipulation of sets of object
+identifiers. The emphasis is on storage and processing efficiency,
+making them suitable for large lists. Note that the ordering of items is
+not preserved over some operations.
+
+Data Structures
+---------------
+
+`struct oid_array`::
+
+ A single array of object IDs. This should be initialized by
+ assignment from `OID_ARRAY_INIT`. The `oid` member contains
+ the actual data. The `nr` member contains the number of items in
+ the set. The `alloc` and `sorted` members are used internally,
+ and should not be needed by API callers.
+
+Functions
+---------
+
+`oid_array_append`::
+ Add an item to the set. The object ID will be placed at the end of
+ the array (but note that some operations below may lose this
+ ordering).
+
+`oid_array_lookup`::
+ Perform a binary search of the array for a specific object ID.
+ If found, returns the offset (in number of elements) of the
+ object ID. If not found, returns a negative integer. If the array
+ is not sorted, this function has the side effect of sorting it.
+
+`oid_array_clear`::
+ Free all memory associated with the array and return it to the
+ initial, empty state.
+
+`oid_array_for_each_unique`::
+ Efficiently iterate over each unique element of the list,
+ executing the callback function for each one. If the array is
+ not sorted, this function has the side effect of sorting it. If
+ the callback returns a non-zero value, the iteration ends
+ immediately and the callback's return is propagated; otherwise,
+ 0 is returned.

- * root, we'll fail to find .git/config (because it's really
- * ../.git/config, etc). See t7006 for a complete set of failures.
- *
- * However, we have historically provided this hack because it does
- * work some of the time (namely when you are at the top-level of a
