+Git v2.2 Release Notes
+======================
+
+Updates since v2.1
+------------------
+
+Ports
+
+ * Building on older MacOS X systems automatically sets
+ the necessary NO_APPLE_COMMON_CRYPTO build-time option.
+
+ * The support to build with NO_PTHREADS has been resurrected.
+
+
+UI, Workflows & Features
+
+ * "git archive" learned to filter what gets archived with pathspec.
+
+ * "git config --edit --global" starts from a skeletal per-user
+ configuration file contents, instead of a total blank, when the
+ user does not already have any. This immediately reduces the
+ need for a later "Have you forgotten setting core.user?" and we
+ can add more to the template as we gain more experience.
+
+ * "git stash list -p" used to be almost always a no-op because each
+ stash entry is represented as a merge commit. It learned to show
+ the difference between the base commit version and the working tree
+ version, which is in line with what "git show" gives.
+
+ * Sometimes users want to report a bug they experience on their
+ repository, but they are not at liberty to share the contents of
+ the repository. "fast-export" was taught an "--anonymize" option
+ to replace blob contents, names of people and paths and log
+ messages with bland and simple strings to help them.
+
+ * "log --date=iso" uses a slight variant of ISO 8601 format that is
+ made more human readable. A new "--date=iso-strict" option gives
+ datetime output that is more strictly conformant.
+
+ * A broken reimplementation of Git could write an invalid index that
+ records both stage #0 and higher stage entries for the same path.
+ We now notice and reject such an index, as there is no sensible
+ fallback (we do not know if the broken tool wanted to resolve and
+ forgot to remove higher stage entries, or if it wanted to unresolve
+ and forgot to remove the stage#0 entry).
+
+ * The temporary files "git mergetool" uses are named to avoid too
+ many dots in them (e.g. a temporary file for "hello.c" used to be
+ named e.g. "hello.BASE.4321.c" but now uses underscore instead,
+ e.g. "hello_BASE_4321.c").
+
+ * The temporary files "git mergetools" uses can be placed in a newly
+ creted temporary directory, instead of the current directory, by
+ setting the mergetool.writeToTemp configuration variable.
+
+ * The "pre-receive" and "post-receive" hooks are no longer required
+ to consume their input fully (not following this requirement used
+ to result in intermittent errors in "git push").
+
+ * The pretty-format specifier "%d", which expanded to " (tagname)"
+ for a tagged commit, gained a cousin "%D" that just gives the
+ "tagname" without frills.
+
+ * "git push" learned "--signed" push, that allows a push (i.e.
+ request to update the refs on the other side to point at a new
+ history, together with the transmission of necessary objects) to be
+ signed, so that it can be verified and audited, using the GPG
+ signature of the person who pushed, that the tips of branches at a
+ public repository really point the commits the pusher wanted to,
+ without having to "trust" the server.
+
+ * "git interpret-trailers" is a new filter to programatically edit
+ the tail end of the commit log messages.
+
+ * "git help everyday" shows the "Everyday Git in 20 commands or so"
+ document, whose contents have been updated to more modern Git
+ practice.
+
+
+Performance, Internal Implementation, etc.
+
+ * The API to manipulate the "refs" has been restructured to make it
+ more transactional, with the eventual goal to allow all-or-none
+ atomic updates and migrating the storage to something other than
+ the traditional filesystem based one (e.g. databases).
+
+ * The lockfile API and its users have been cleaned up.
+
+ * We no longer attempt to keep track of individual dependencies to
+ the header files in the build procedure, relying on automated
+ dependency generation support from modern compilers.
+
+ * In tests, we have been using NOT_{MINGW,CYGWIN} test prerequisites
+ long before negated prerequisites e.g. !MINGW were invented.
+ The former has been converted to the latter to avoid confusion.
+
+ * Looking up remotes configuration in a repository with very many
+ remotes defined has been optimized.
+
+ * There are cases where you lock and open to write a file, close it
+ to show the updated contents to external processes, and then have
+ to update the file again while still holding the lock, but the
+ lockfile API lacked support for such an access pattern.
+
+ * The API to allocate the structure to keep track of commit
+ decoration has been updated to make it less cumbersome to use.
+
+ * An in-core caching layer to let us avoid reading the same
+ configuration files number of times has been added. A few commands
+ have been converted to use this subsystem.
+
+ * Various code paths have been cleaned up and simplified by using
+ "strbuf", "starts_with()", and "skip_prefix()" APIs more.
+
+ * A few codepaths that died when large blobs that would not fit in
+ core are involved in their operation have been taught to punt
+ instead, by e.g. marking too large a blob as not to be diffed.
+
+ * A few more code paths in "commit" and "checkout" have been taught
+ to repopulate the cache-tree in the index, to help speed up later
+ "write-tree" (used in "commit") and "diff-index --cached" (used in
+ "status").
+
+ * A common programming mistake to assign the same short option name
+ to two separate options is detected by parse_options() API to help
+ developers.
+
+ * The code path to write out the packed-refs file has been optimized,
+ which especially matters in a repository with a large number of
+ refs.
+
+ * The check to see if a ref $F can be created by making sure no
+ existing ref has $F/ as its prefix has been optimized, which
+ especially matters in a repository with a large number of existing
+ refs.
+
+ * "git fsck" was taught to check contents of tag objects a bit more.
+
+ * "git hash-object" was taught a "--literally" option to help
+ debugging.
+
+ * When running a required clean filter, we do not have to mmap the
+ original before feeding the filter. Instead, stream the file
+ contents directly to the filter and process its output.
+
+ * The scripts in the test suite can be run with "-x" option to show
+ a shell-trace of each command run in them.
+
+ * The "run-command" API learned to manage the argv and environment
+ array for child process, alleviating the need for the callers to
+ allocate and deallocate them.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.1
+----------------
+
+Unless otherwise noted, all the fixes since v2.1 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git log --pretty/format=" with an empty format string did not
+ mean the more obvious "No output whatsoever" but "Use default
+ format", which was counterintuitive.
+
+ * "git -c section.var command" and "git -c section.var= command"
+ should pass the configuration differently (the former should be a
+ boolean true, the latter should be an empty string).
+
+ * Applying a patch not generated by Git in a subdirectory used to
+ check the whitespace breakage using the attributes for incorrect
+ paths. Also whitespace checks were performed even for paths
+ excluded via "git apply --exclude=<path>" mechanism.
+
+ * "git bundle create" with date-range specification were meant to
+ exclude tags outside the range, but it didn't.
+
+ * "git add x" where x that used to be a directory has become a
+ symbolic link to a directory misbehaved.
+
+ * The prompt script checked $GIT_DIR/ref/stash file to see if there
+ is a stash, which was a no-no.
+
+ * Pack-protocol documentation had a minor typo.
+
+ * "git checkout -m" did not switch to another branch while carrying
+ the local changes forward when a path was deleted from the index.
+
+ * "git daemon" (with NO_IPV6 build configuration) used to incorrectly
+ use the hostname even when gethostbyname() reported that the given
+ hostname is not found.
+ (merge 107efbe rs/daemon-fixes later to maint).
+
+ * With sufficiently long refnames, "git fast-import" could have
+ overflown an on-stack buffer.
+
+ * After "pack-refs --prune" packed refs at the top-level, it failed
+ to prune them.
+
+ * Progress output from "git gc --auto" was visible in "git fetch -q".
+
+ * We used to pass -1000 to poll(2), expecting it to also mean "no
+ timeout", which should be spelled as -1.
+
+ * "git rebase" documentation was unclear that it is required to
+ specify on what <upstream> the rebase is to be done when telling it
+ to first check out <branch>.
+ (merge 95c6826 so/rebase-doc later to maint).
+
+ * "git push" over HTTP transport had an artificial limit on number of
+ refs that can be pushed imposed by the command line length.
+ (merge 26be19b jk/send-pack-many-refspecs later to maint).
+
+ * When receiving an invalid pack stream that records the same object
+ twice, multiple threads got confused due to a race.
+ (merge ab791dd jk/index-pack-threading-races later to maint).
+
+ * An attempt to remove the entire tree in the "git fast-import" input
+ stream caused it to misbehave.
+ (merge 2668d69 mb/fast-import-delete-root later to maint).
+
+ * Reachability check (used in "git prune" and friends) did not add a
+ detached HEAD as a starting point to traverse objects still in use.
+ (merge c40fdd0 mk/reachable-protect-detached-head later to maint).
+
+ * "git config --add section.var val" used to lose existing
+ section.var whose value was an empty string.
+ (merge c1063be ta/config-add-to-empty-or-true-fix later to maint).
+
+ * "git fsck" failed to report that it found corrupt objects via its
+ exit status in some cases.
+ (merge 30d1038 jk/fsck-exit-code-fix later to maint).
+
+ * Use of "--verbose" option used to break "git branch --merged".
+ (merge 12994dd jk/maint-branch-verbose-merged later to maint).
+
+ * Some MUAs mangled a line in a message that begins with "From " to
+ ">From " when writing to a mailbox file and feeding such an input
+ to "git am" used to lose such a line.
+ (merge 85de86a jk/mbox-from-line later to maint).
+
+ * "rev-parse --verify --quiet $name" is meant to quietly exit with a
+ non-zero status when $name is not a valid object name, but still
+ gave error messages in some cases.
+
+ * A handful of C source files have been updated to include
+ "git-compat-util.h" as the first thing, to conform better to our
+ coding guidelines.
+ (merge 1c4b660 da/include-compat-util-first-in-c later to maint).
+
+ * t7004 test, which tried to run Git with small stack space, has been
+ updated to give a bit larger stack to avoid false breakage on some
+ platforms.
+ (merge b9a1907 sk/tag-contains-wo-recursion later to maint).
+
+ * A few documentation pages had example sections marked up not quite
+ correctly, which passed AsciiDoc but failed with AsciiDoctor.
+ (merge c30c43c bc/asciidoc-pretty-formats-fix later to maint).
+ (merge f8a48af bc/asciidoc later to maint).
+
+ * "gitweb" used deprecated CGI::startfrom, which was removed from
+ CGI.pm as of 4.04; use CGI::start_from instead.
+ (merge 4750f4b rm/gitweb-start-form later to maint).
+
+ * Newer versions of 'meld' breaks the auto-detection we use to see if
+ they are new enough to support the `--output` option.
+ (merge b12d045 da/mergetool-meld later to maint).
+
+ * "git pack-objects" forgot to disable the codepath to generate
+ object recheability bitmap when it needs to split the resulting
+ pack.
+ (merge 2113471 jk/pack-objects-no-bitmap-when-splitting later to maint).
--
core.fileMode::
- If false, the executable bit differences between the index and
- the working tree are ignored; useful on broken filesystems like FAT.
- See linkgit:git-update-index[1].
+ Tells Git if the executable bit of files in the working tree
+ is to be honored.
+
-The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
-will probe and set core.fileMode false if appropriate when the
-repository is created.
+Some filesystems lose the executable bit when a file that is
+marked as executable is checked out, or checks out an
+non-executable file with executable bit on.
+linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem
+to see if it handles the executable bit correctly
+and this variable is automatically set as necessary.
++
+A repository, however, may be on a filesystem that handles
+the filemode correctly, and this variable is set to 'true'
+when created, but later may be made accessible from another
+environment that loses the filemode (e.g. exporting ext4 via
+CIFS mount, visiting a Cygwin created repository with
+Git for Windows or Eclipse).
+In such a case it may be necessary to set this variable to 'false'.
+See linkgit:git-update-index[1].
++
+The default is true (when core.filemode is not specified in the config file).
core.ignorecase::
If true, this option enables various workarounds to enable
Files larger than this size are stored deflated, without
attempting delta compression. Storing large files without
delta compression avoids excessive memory usage, at the
- slight expense of increased disk usage.
+ slight expense of increased disk usage. Additionally files
+ larger than this size are always treated as binary.
+
Default is 512 MiB on all platforms. This should be reasonable
for most projects as source code and other text files can still
if the file has been updated, otherwise the user is prompted to
indicate the success of the merge.
+mergetool.meld.hasOutput::
+ Older versions of `meld` do not support the `--output` option.
+ Git will attempt to detect whether `meld` supports `--output`
+ by inspecting the output of `meld --help`. Configuring
+ `mergetool.meld.hasOutput` will make Git skip these checks and
+ use the configured value instead. Setting `mergetool.meld.hasOutput`
+ to `true` tells Git to unconditionally use the `--output` option,
+ and `false` avoids using `--output`.
+
mergetool.keepBackup::
After performing a merge, the original file with conflict markers
can be saved as a file with a `.orig` extension. If this variable
preserved, otherwise they will be removed after the tool has
exited. Defaults to `false`.
+mergetool.writeToTemp::
+ Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
+ conflicting files in the worktree by default. Git will attempt
+ to use a temporary directory for these files when set `true`.
+ Defaults to `false`.
+
mergetool.prompt::
Prompt before each invocation of the merge resolution program.
receiving data from git-push and updating refs. You can stop
it by setting this variable to false.
+receive.certnonceseed::
+ By setting this variable to a string, `git receive-pack`
+ will accept a `git push --signed` and verifies it by using
+ a "nonce" protected by HMAC using this string as a secret
+ key.
+
+receive.certnonceslop::
+ When a `git push --signed` sent a push certificate with a
+ "nonce" that was issued by a receive-pack serving the same
+ repository within this many seconds, export the "nonce"
+ found in the certificate to `GIT_PUSH_CERT_NONCE` to the
+ hooks (instead of what the receive-pack asked the sending
+ side to include). This may allow writing checks in
+ `pre-receive` and `post-receive` a bit easier. Instead of
+ checking `GIT_PUSH_CERT_NONCE_SLOP` environment variable
+ that records by how many seconds the nonce is stale to
+ decide if they want to accept the certificate, they only
+ can check `GIT_PUSH_CERT_NONCE_STATUS` is `OK`.
+
receive.fsckObjects::
If it is set to true, git-receive-pack will check all received
objects. It will abort in the case of a malformed object or a

-Everyday Git With 20 Commands Or So
-===================================
-
-<<Individual Developer (Standalone)>> commands are essential for
-anybody who makes a commit, even for somebody who works alone.
-
-If you work with other people, you will need commands listed in
-the <<Individual Developer (Participant)>> section as well.
-
-People who play the <<Integrator>> role need to learn some more
-commands in addition to the above.
-
-<<Repository Administration>> commands are for system
-administrators who are responsible for the care and feeding
-of Git repositories.
-
-
-Individual Developer (Standalone)[[Individual Developer (Standalone)]]
-----------------------------------------------------------------------
-
-A standalone individual developer does not exchange patches with
-other people, and works alone in a single repository, using the
-following commands.
-
- * linkgit:git-init[1] to create a new repository.
-
- * linkgit:git-show-branch[1] to see where you are.
-
- * linkgit:git-log[1] to see what happened.
-
- * linkgit:git-checkout[1] and linkgit:git-branch[1] to switch
- branches.
-
- * linkgit:git-add[1] to manage the index file.
-
- * linkgit:git-diff[1] and linkgit:git-status[1] to see what
- you are in the middle of doing.
-
- * linkgit:git-commit[1] to advance the current branch.
-
- * linkgit:git-reset[1] and linkgit:git-checkout[1] (with
- pathname parameters) to undo changes.
-
- * linkgit:git-merge[1] to merge between local branches.
-
- * linkgit:git-rebase[1] to maintain topic branches.
-
- * linkgit:git-tag[1] to mark known point.
-
-Examples
-~~~~~~~~
-
-Use a tarball as a starting point for a new repository.::
-+
-------------
-$ tar zxf frotz.tar.gz
-$ cd frotz
-$ git init
-$ git add . <1>
-$ git commit -m "import of frotz source tree."
-$ git tag v2.43 <2>
-------------
-+
-<1> add everything under the current directory.
-<2> make a lightweight, unannotated tag.
-
-Create a topic branch and develop.::
-+
-------------
-$ git checkout -b alsa-audio <1>
-$ edit/compile/test
-$ git checkout -- curses/ux_audio_oss.c <2>
-$ git add curses/ux_audio_alsa.c <3>
-$ edit/compile/test
-$ git diff HEAD <4>
-$ git commit -a -s <5>
-$ edit/compile/test
-$ git reset --soft HEAD^ <6>
-$ edit/compile/test
-$ git diff ORIG_HEAD <7>
-$ git commit -a -c ORIG_HEAD <8>
-$ git checkout master <9>
-$ git merge alsa-audio <10>
-$ git log --since='3 days ago' <11>
-$ git log v2.43.. curses/ <12>
-------------
-+
-<1> create a new topic branch.
-<2> revert your botched changes in `curses/ux_audio_oss.c`.
-<3> you need to tell Git if you added a new file; removal and
-modification will be caught if you do `git commit -a` later.
-<4> to see what changes you are committing.
-<5> commit everything as you have tested, with your sign-off.
-<6> take the last commit back, keeping what is in the working tree.
-<7> look at the changes since the premature commit we took back.
-<8> redo the commit undone in the previous step, using the message
-you originally wrote.
-<9> switch to the master branch.
-<10> merge a topic branch into your master branch.
-<11> review commit logs; other forms to limit output can be
-combined and include `--max-count=10` (show 10 commits),
-`--until=2005-12-10`, etc.
-<12> view only the changes that touch what's in `curses/`
-directory, since `v2.43` tag.
-
-
-Individual Developer (Participant)[[Individual Developer (Participant)]]
-------------------------------------------------------------------------
-
-A developer working as a participant in a group project needs to
-learn how to communicate with others, and uses these commands in
-addition to the ones needed by a standalone developer.
-
- * linkgit:git-clone[1] from the upstream to prime your local
- repository.
-
- * linkgit:git-pull[1] and linkgit:git-fetch[1] from "origin"
- to keep up-to-date with the upstream.
-
- * linkgit:git-push[1] to shared repository, if you adopt CVS
- style shared repository workflow.
-
- * linkgit:git-format-patch[1] to prepare e-mail submission, if
- you adopt Linux kernel-style public forum workflow.
-
-Examples
-~~~~~~~~
-
-Clone the upstream and work on it. Feed changes to upstream.::
-+
-------------
-$ git clone git://git.kernel.org/pub/scm/.../torvalds/linux-2.6 my2.6
-$ cd my2.6
-$ edit/compile/test; git commit -a -s <1>
-$ git format-patch origin <2>
-$ git pull <3>
-$ git log -p ORIG_HEAD.. arch/i386 include/asm-i386 <4>
-$ git pull git://git.kernel.org/pub/.../jgarzik/libata-dev.git ALL <5>
-$ git reset --hard ORIG_HEAD <6>
-$ git gc <7>
-$ git fetch --tags <8>
-------------
-+
-<1> repeat as needed.
-<2> extract patches from your branch for e-mail submission.
-<3> `git pull` fetches from `origin` by default and merges into the
-current branch.
-<4> immediately after pulling, look at the changes done upstream
-since last time we checked, only in the
-area we are interested in.
-<5> fetch from a specific branch from a specific repository and merge.
-<6> revert the pull.
-<7> garbage collect leftover objects from reverted pull.
-<8> from time to time, obtain official tags from the `origin`
-and store them under `.git/refs/tags/`.
-
-
-Push into another repository.::
-+
-------------
-satellite$ git clone mothership:frotz frotz <1>
-satellite$ cd frotz
-satellite$ git config --get-regexp '^(remote|branch)\.' <2>
-remote.origin.url mothership:frotz

-------------
-+
-<1> mothership machine has a frotz repository under your home
-directory; clone from it to start a repository on the satellite
-machine.
-<2> clone sets these configuration variables by default.
-It arranges `git pull` to fetch and store the branches of mothership
-machine to local `remotes/origin/*` remote-tracking branches.
-<3> arrange `git push` to push local `master` branch to
-`remotes/satellite/master` branch of the mothership machine.
-<4> push will stash our work away on `remotes/satellite/master`
-remote-tracking branch on the mothership machine. You could use this
-as a back-up method.
-<5> on mothership machine, merge the work done on the satellite
-machine into the master branch.

-$ git checkout -b private2.6.14 v2.6.14 <1>
-$ edit/compile/test; git commit -a
-$ git checkout master
-$ git format-patch -k -m --stdout v2.6.14..private2.6.14 |
- git am -3 -k <2>
-------------
-+
-<1> create a private branch based on a well known (but somewhat behind)
-tag.
-<2> forward port all changes in `private2.6.14` branch to `master` branch
-without a formal "merging".

-$ git push ko v0.99.9x <13>
-------------
-+
-<1> see what I was in the middle of doing, if any.
-<2> see what topic branches I have and think about how ready
-they are.
-<3> read mails, save ones that are applicable, and save others
-that are not quite ready.
-<4> apply them, interactively, with my sign-offs.
-<5> create topic branch as needed and apply, again with my
-sign-offs.
-<6> rebase internal topic branch that has not been merged to the
-master or exposed as a part of a stable branch.
-<7> restart `pu` every time from the next.
-<8> and bundle topic branches still cooking.
-<9> backport a critical fix.
-<10> create a signed tag.
-<11> make sure I did not accidentally rewind master beyond what I
-already pushed out. `ko` shorthand points at the repository I have
-at kernel.org, and looks like this:
-+
-------------
-$ cat .git/remotes/ko
-URL: kernel.org:/pub/scm/git/git.git
-Pull: master:refs/tags/ko-master
-Pull: next:refs/tags/ko-next
-Pull: maint:refs/tags/ko-maint
-Push: master
-Push: next
-Push: +pu
-Push: maint
-------------
-+
-In the output from `git show-branch`, `master` should have
-everything `ko-master` has, and `next` should have
-everything `ko-next` has.
-
-<12> push out the bleeding edge.
-<13> push the tag out, too.

-Repository Administration[[Repository Administration]]
-------------------------------------------------------
-
-A repository administrator uses the following tools to set up
-and maintain access to the repository by developers.
-
- * linkgit:git-daemon[1] to allow anonymous download from
- repository.
-
- * linkgit:git-shell[1] can be used as a 'restricted login shell'
- for shared central repository users.
-
-link:howto/update-hook-example.html[update hook howto] has a good
-example of managing a shared central repository.
-
-
-Examples
-~~~~~~~~
-We assume the following in /etc/services::
-+
-------------
-$ grep 9418 /etc/services
-git 9418/tcp # Git Version Control System
-------------
-
-Run git-daemon to serve /pub/scm from inetd.::
-+
-------------
-$ grep git /etc/inetd.conf
-git stream tcp nowait nobody \
- /usr/bin/git-daemon git-daemon --inetd --export-all /pub/scm
-------------
-+
-The actual configuration line should be on one line.
-
-Run git-daemon to serve /pub/scm from xinetd.::
-+
-------------
-$ cat /etc/xinetd.d/git-daemon
-# default: off
-# description: The Git server offers access to Git repositories
-service git

- user = nobody
- server = /usr/bin/git-daemon
- server_args = --inetd --export-all --base-path=/pub/scm
- log_on_failure += USERID
-}
-------------
-+
-Check your xinetd(8) documentation and setup, this is from a Fedora system.
-Others might be different.

-/usr/bin/git-shell
-------------
-+
-<1> log-in shell is set to /usr/bin/git-shell, which does not
-allow anything but `git push` and `git pull`. The users should
-get an ssh access to the machine.
-<2> in many distributions /etc/shells needs to list what is used

GIT
---
Part of the linkgit:git[1] suite
in the commit (as opposed to just listing the files which are
different from the commit's first parent).
+--anonymize::
+ Anonymize the contents of the repository while still retaining
+ the shape of the history and stored tree. See the section on
+ `ANONYMIZING` below.
+
--refspec::
Apply the specified refspec to each ref exported. Multiple of them can
be specified.
'refs/heads/master'.
+ANONYMIZING
+-----------
+
+If the `--anonymize` option is given, git will attempt to remove all
+identifying information from the repository while still retaining enough
+of the original tree and history patterns to reproduce some bugs. The
+goal is that a git bug which is found on a private repository will
+persist in the anonymized repository, and the latter can be shared with
+git developers to help solve the bug.
+
+With this option, git will replace all refnames, paths, blob contents,
+commit and tag messages, names, and email addresses in the output with
+anonymized data. Two instances of the same string will be replaced
+equivalently (e.g., two commits with the same author will have the same
+anonymized author in the output, but bear no resemblance to the original
+author string). The relationship between commits, branches, and tags is
+retained, as well as the commit timestamps (but the commit messages and
+refnames bear no resemblance to the originals). The relative makeup of
+the tree is retained (e.g., if you have a root tree with 10 files and 3
+trees, so will the output), but their names and the contents of the
+files will be replaced.
+
+If you think you have found a git bug, you can start by exporting an
+anonymized stream of the whole repository:
+
+---------------------------------------------------
+$ git fast-export --anonymize --all >anon-stream
+---------------------------------------------------
+
+Then confirm that the bug persists in a repository created from that
+stream (many bugs will not, as they really do depend on the exact
+repository contents):
+
+---------------------------------------------------
+$ git init anon-repo
+$ cd anon-repo
+$ git fast-import <../anon-stream
+$ ... test your bug ...
+---------------------------------------------------
+
+If the anonymized repository shows the bug, it may be worth sharing
+`anon-stream` along with a regular bug report. Note that the anonymized
+stream compresses very well, so gzipping it is encouraged. If you want
+to examine the stream to see that it does not contain any private data,
+you can peruse it directly before sending. You may also want to try:
+
+---------------------------------------------------
+$ perl -pe 's/\d+/X/g' <anon-stream | sort -u | less
+---------------------------------------------------
+
+which shows all of the unique lines (with numbers converted to "X", to
+collapse "User 0", "User 1", etc into "User X"). This produces a much
+smaller output, and it is usually easy to quickly confirm that there is
+no private data in the stream.
+
+

--separate-git-dir=<git dir>::
-Instead of initializing the repository where it is supposed to be,

-specified path, and initialize a Git repository at the path. The
-result is Git repository can be separated from working tree. If this

-path.
+Instead of initializing the repository as a directory to either `$GIT_DIR` or

by umask(2).
-
++
The option can have the following values, defaulting to 'group' if no value
is given:
++
+--
+'umask' (or 'false')::
- - 'umask' (or 'false'): Use permissions reported by umask(2). The default,
- when `--shared` is not specified.

+specified.
- - 'group' (or 'true'): Make the repository group-writable, (and g+sx, since
- the git group may be not the primary group of all users).
- This is used to loosen the permissions of an otherwise safe umask(2) value.
- Note that the umask still applies to the other permission bits (e.g. if
- umask is '0022', using 'group' will not remove read privileges from other
- (non-group) users). See '0xxx' for how to exactly specify the repository

+git-interpret-trailers(1)
+=========================
+
+NAME
+----
+git-interpret-trailers - help add stuctured information into commit messages
+
+SYNOPSIS
+--------
+[verse]
+'git interpret-trailers' [--trim-empty] [(--trailer <token>[(=|:)<value>])...] [<file>...]
+
+DESCRIPTION
+-----------
+Help adding 'trailers' lines, that look similar to RFC 822 e-mail
+headers, at the end of the otherwise free-form part of a commit
+message.
+
+This command reads some patches or commit messages from either the
+<file> arguments or the standard input if no <file> is specified. Then
+this command applies the arguments passed using the `--trailer`
+option, if any, to the commit message part of each input file. The
+result is emitted on the standard output.
+
+Some configuration variables control the way the `--trailer` arguments
+are applied to each commit message and the way any existing trailer in
+the commit message is changed. They also make it possible to
+automatically add some trailers.
+
+By default, a '<token>=<value>' or '<token>:<value>' argument given
+using `--trailer` will be appended after the existing trailers only if
+the last trailer has a different (<token>, <value>) pair (or if there
+is no existing trailer). The <token> and <value> parts will be trimmed
+to remove starting and trailing whitespace, and the resulting trimmed
+<token> and <value> will appear in the message like this:
+
+------------------------------------------------
+token: value
+------------------------------------------------
+
+This means that the trimmed <token> and <value> will be separated by
+`': '` (one colon followed by one space).
+
+By default the new trailer will appear at the end of all the existing
+trailers. If there is no existing trailer, the new trailer will appear
+after the commit message part of the ouput, and, if there is no line
+with only spaces at the end of the commit message part, one blank line
+will be added before the new trailer.
+
+Existing trailers are extracted from the input message by looking for
+a group of one or more lines that contain a colon (by default), where
+the group is preceded by one or more empty (or whitespace-only) lines.
+The group must either be at the end of the message or be the last
+non-whitespace lines before a line that starts with '---'. Such three
+minus signs start the patch part of the message.
+
+When reading trailers, there can be whitespaces before and after the
+token, the separator and the value. There can also be whitespaces
+indide the token and the value.
+
+Note that 'trailers' do not follow and are not intended to follow many
+rules for RFC 822 headers. For example they do not follow the line
+folding rules, the encoding rules and probably many other rules.
+
+OPTIONS
+-------
+--trim-empty::
+ If the <value> part of any trailer contains only whitespace,
+ the whole trailer will be removed from the resulting message.
+ This apply to existing trailers as well as new trailers.
+
+--trailer <token>[(=|:)<value>]::
+ Specify a (<token>, <value>) pair that should be applied as a
+ trailer to the input messages. See the description of this
+ command.
+
+CONFIGURATION VARIABLES
+-----------------------
+
+trailer.separators::
+ This option tells which characters are recognized as trailer
+ separators. By default only ':' is recognized as a trailer
+ separator, except that '=' is always accepted on the command
+ line for compatibility with other git commands.
++
+The first character given by this option will be the default character
+used when another separator is not specified in the config for this
+trailer.
++
+For example, if the value for this option is "%=$", then only lines
+using the format '<token><sep><value>' with <sep> containing '%', '='
+or '$' and then spaces will be considered trailers. And '%' will be
+the default separator used, so by default trailers will appear like:
+'<token>% <value>' (one percent sign and one space will appear between
+the token and the value).
+
+trailer.where::
+ This option tells where a new trailer will be added.
++
+This can be `end`, which is the default, `start`, `after` or `before`.
++
+If it is `end`, then each new trailer will appear at the end of the
+existing trailers.
++
+If it is `start`, then each new trailer will appear at the start,
+instead of the end, of the existing trailers.
++
+If it is `after`, then each new trailer will appear just after the
+last trailer with the same <token>.
++
+If it is `before`, then each new trailer will appear just before the
+first trailer with the same <token>.
+
+trailer.ifexists::
+ This option makes it possible to choose what action will be
+ performed when there is already at least one trailer with the
+ same <token> in the message.
++
+The valid values for this option are: `addIfDifferentNeighbor` (this
+is the default), `addIfDifferent`, `add`, `overwrite` or `doNothing`.
++
+With `addIfDifferentNeighbor`, a new trailer will be added only if no
+trailer with the same (<token>, <value>) pair is above or below the line
+where the new trailer will be added.
++
+With `addIfDifferent`, a new trailer will be added only if no trailer
+with the same (<token>, <value>) pair is already in the message.
++
+With `add`, a new trailer will be added, even if some trailers with
+the same (<token>, <value>) pair are already in the message.
++
+With `replace`, an existing trailer with the same <token> will be
+deleted and the new trailer will be added. The deleted trailer will be
+the closest one (with the same <token>) to the place where the new one
+will be added.
++
+With `doNothing`, nothing will be done; that is no new trailer will be
+added if there is already one with the same <token> in the message.
+
+trailer.ifmissing::
+ This option makes it possible to choose what action will be
+ performed when there is not yet any trailer with the same
+ <token> in the message.
++
+The valid values for this option are: `add` (this is the default) and
+`doNothing`.
++
+With `add`, a new trailer will be added.
++
+With `doNothing`, nothing will be done.
+
+trailer.<token>.key::
+ This `key` will be used instead of <token> in the trailer. At
+ the end of this key, a separator can appear and then some
+ space characters. By default the only valid separator is ':',
+ but this can be changed using the `trailer.separators` config
+ variable.
++
+If there is a separator, then the key will be used instead of both the
+<token> and the default separator when adding the trailer.
+
+trailer.<token>.where::
+ This option takes the same values as the 'trailer.where'
+ configuration variable and it overrides what is specified by
+ that option for trailers with the specified <token>.
+
+trailer.<token>.ifexist::
+ This option takes the same values as the 'trailer.ifexist'
+ configuration variable and it overrides what is specified by
+ that option for trailers with the specified <token>.
+
+trailer.<token>.ifmissing::
+ This option takes the same values as the 'trailer.ifmissing'
+ configuration variable and it overrides what is specified by
+ that option for trailers with the specified <token>.
+
+trailer.<token>.command::
+ This option can be used to specify a shell command that will
+ be called to automatically add or modify a trailer with the
+ specified <token>.
++
+When this option is specified, the behavior is as if a special
+'<token>=<value>' argument were added at the beginning of the command
+line, where <value> is taken to be the standard output of the
+specified command with any leading and trailing whitespace trimmed
+off.
++
+If the command contains the `$ARG` string, this string will be
+replaced with the <value> part of an existing trailer with the same
+<token>, if any, before the command is launched.
++
+If some '<token>=<value>' arguments are also passed on the command
+line, when a 'trailer.<token>.command' is configured, the command will
+also be executed for each of these arguments. And the <value> part of
+these arguments, if any, will be used to replace the `$ARG` string in
+the command.
+
+EXAMPLES
+--------
+
+* Configure a 'sign' trailer with a 'Signed-off-by' key, and then
+ add two of these trailers to a message:
++
+------------
+$ git config trailer.sign.key "Signed-off-by"
+$ cat msg.txt
+subject
+
+message
+$ cat msg.txt | git interpret-trailers --trailer 'sign: Alice <alice@example.com>' --trailer 'sign: Bob <bob@example.com>'
+subject
+
+message
+
+Signed-off-by: Alice <alice@example.com>
+Signed-off-by: Bob <bob@example.com>
+------------
+
+* Extract the last commit as a patch, and add a 'Cc' and a
+ 'Reviewed-by' trailer to it:
++
+------------
+$ git format-patch -1
+0001-foo.patch
+$ git interpret-trailers --trailer 'Cc: Alice <alice@example.com>' --trailer 'Reviewed-by: Bob <bob@example.com>' 0001-foo.patch >0001-bar.patch
+------------
+
+* Configure a 'sign' trailer with a command to automatically add a
+ 'Signed-off-by: ' with the author information only if there is no
+ 'Signed-off-by: ' already, and show how it works:
++
+------------
+$ git config trailer.sign.key "Signed-off-by: "
+$ git config trailer.sign.ifmissing add
+$ git config trailer.sign.ifexists doNothing
+$ git config trailer.sign.command 'echo "$(git config user.name) <$(git config user.email)>"'
+$ git interpret-trailers <<EOF
+> EOF
+
+Signed-off-by: Bob <bob@example.com>
+$ git interpret-trailers <<EOF
+> Signed-off-by: Alice <alice@example.com>
+> EOF
+
+Signed-off-by: Alice <alice@example.com>
+------------
+
+* Configure a 'fix' trailer with a key that contains a '#' and no
+ space after this character, and show how it works:
++
+------------
+$ git config trailer.separators ":#"
+$ git config trailer.fix.key "Fix #"
+$ echo "subject" | git interpret-trailers --trailer fix=42
+subject
+
+Fix #42
+------------
+
+* Configure a 'see' trailer with a command to show the subject of a
+ commit that is related, and show how it works:
++
+------------
+$ git config trailer.see.key "See-also: "
+$ git config trailer.see.ifExists "replace"
+$ git config trailer.see.ifMissing "doNothing"
+$ git config trailer.see.command "git log -1 --oneline --format=\"%h (%s)\" --abbrev-commit --abbrev=14 \$ARG"
+$ git interpret-trailers <<EOF
+> subject
+>
+> message
+>
+> see: HEAD~2
+> EOF
+subject
+
+message
+
+See-also: fe3187489d69c4 (subject of related commit)
+------------
+
+* Configure a commit template with some trailers with empty values
+ (using sed to show and keep the trailing spaces at the end of the
+ trailers), then configure a commit-msg hook that uses
+ 'git interpret-trailers' to remove trailers with empty values and
+ to add a 'git-version' trailer:
++
+------------
+$ sed -e 's/ Z$/ /' >commit_template.txt <<EOF
+> ***subject***
+>
+> ***message***
+>
+> Fixes: Z
+> Cc: Z
+> Reviewed-by: Z
+> Signed-off-by: Z
+> EOF
+$ git config commit.template commit_template.txt
+$ cat >.git/hooks/commit-msg <<EOF
+> #!/bin/sh
+> git interpret-trailers --trim-empty --trailer "git-version: \$(git describe)" "\$1" > "\$1.new"
+> mv "\$1.new" "\$1"
+> EOF
+$ chmod +x .git/hooks/commit-msg

All changes made by commits in the current branch but that are not

+When accepting a signed push (see linkgit:git-push[1]), the signed
+push certificate is stored in a blob and an environment variable
+`GIT_PUSH_CERT` can be consulted for its object name. See the
+description of `post-receive` hook for an example. In addition, the
+certificate is verified using GPG and the result is exported with
+the following environment variables:
+
+`GIT_PUSH_CERT_SIGNER`::
+ The name and the e-mail address of the owner of the key that
+ signed the push certificate.
+
+`GIT_PUSH_CERT_KEY`::
+ The GPG key ID of the key that signed the push certificate.
+
+`GIT_PUSH_CERT_STATUS`::
+ The status of GPG verification of the push certificate,
+ using the same mnemonic as used in `%G?` format of `git log`
+ family of commands (see linkgit:git-log[1]).
+
+`GIT_PUSH_CERT_NONCE`::
+ The nonce string the process asked the signer to include
+ in the push certificate. If this does not match the value
+ recorded on the "nonce" header in the push certificate, it
+ may indicate that the certificate is a valid one that is
+ being replayed from a separate "git push" session.
+
+`GIT_PUSH_CERT_NONCE_STATUS`::
+`UNSOLICITED`;;
+ "git push --signed" sent a nonce when we did not ask it to
+ send one.
+`MISSING`;;
+ "git push --signed" did not send any nonce header.
+`BAD`;;
+ "git push --signed" sent a bogus nonce.
+`OK`;;
+ "git push --signed" sent the nonce we asked it to send.
+`SLOP`;;
+ "git push --signed" sent a nonce different from what we
+ asked it to send now, but in a previous session. See
+ `GIT_PUSH_CERT_NONCE_SLOP` environment variable.
+
+`GIT_PUSH_CERT_NONCE_SLOP`::
+ "git push --signed" sent a nonce different from what we
+ asked it to send now, but in a different session whose
+ starting time is different by this many seconds from the

+ `GIT_PUSH_CERT_NONCE_STATUS` says `SLOP`.
+ Also read about `receive.certnonceslop` variable in

This hook is called before any refname is updated and before any
fast-forward checks are performed.
0\{40}, otherwise sha1-old and sha1-new should be valid objects in
the repository.
+The `GIT_PUSH_CERT*` environment variables can be inspected, just as
+in `pre-receive` hook, after accepting a signed push.
+
Using this hook, it is easy to generate mails describing the updates
to the repository. This example script sends one mail message per
-ref listing the commits pushed to the repository:
+ref listing the commits pushed to the repository, and logs the push
+certificates of signed pushes with good signatures to a logger
+service:

+NAME
+----
+giteveryday - A useful minimum set of commands for Everyday Git
+
+SYNOPSIS
+--------
+
+Everyday Git With 20 Commands Or So
+
+DESCRIPTION
+-----------
+
+Git users can broadly be grouped into four categories for the purposes of
+describing here a small set of useful command for everyday Git.
+
+* <<STANDALONE,Individual Developer (Standalone)>> commands are essential
+ for anybody who makes a commit, even for somebody who works alone.
+
+* If you work with other people, you will need commands listed in
+ the <<PARTICIPANT,Individual Developer (Participant)>> section as well.
+
+* People who play the <<INTEGRATOR,Integrator>> role need to learn some
+ more commands in addition to the above.
+
+* <<ADMINISTRATION,Repository Administration>> commands are for system
+ administrators who are responsible for the care and feeding
+ of Git repositories.
+
+
+Individual Developer (Standalone)[[STANDALONE]]
+-----------------------------------------------
+
+A standalone individual developer does not exchange patches with
+other people, and works alone in a single repository, using the
+following commands.
+
+ * linkgit:git-init[1] to create a new repository.
+
+ * linkgit:git-log[1] to see what happened.
+
+ * linkgit:git-checkout[1] and linkgit:git-branch[1] to switch
+ branches.
+
+ * linkgit:git-add[1] to manage the index file.
+
+ * linkgit:git-diff[1] and linkgit:git-status[1] to see what
+ you are in the middle of doing.
+
+ * linkgit:git-commit[1] to advance the current branch.
+
+ * linkgit:git-reset[1] and linkgit:git-checkout[1] (with
+ pathname parameters) to undo changes.
+
+ * linkgit:git-merge[1] to merge between local branches.
+
+ * linkgit:git-rebase[1] to maintain topic branches.
+
+ * linkgit:git-tag[1] to mark a known point.
+
+Examples
+~~~~~~~~
+
+Use a tarball as a starting point for a new repository.::
++
+------------
+$ tar zxf frotz.tar.gz
+$ cd frotz
+$ git init
+$ git add . <1>
+$ git commit -m "import of frotz source tree."
+$ git tag v2.43 <2>
+------------
++
+<1> add everything under the current directory.
+<2> make a lightweight, unannotated tag.
+
+Create a topic branch and develop.::
++
+------------
+$ git checkout -b alsa-audio <1>
+$ edit/compile/test
+$ git checkout -- curses/ux_audio_oss.c <2>
+$ git add curses/ux_audio_alsa.c <3>
+$ edit/compile/test
+$ git diff HEAD <4>
+$ git commit -a -s <5>
+$ edit/compile/test
+$ git diff HEAD^ <6>
+$ git commit -a --amend <7>
+$ git checkout master <8>
+$ git merge alsa-audio <9>
+$ git log --since='3 days ago' <10>
+$ git log v2.43.. curses/ <11>
+------------
++
+<1> create a new topic branch.
+<2> revert your botched changes in `curses/ux_audio_oss.c`.
+<3> you need to tell Git if you added a new file; removal and
+modification will be caught if you do `git commit -a` later.
+<4> to see what changes you are committing.
+<5> commit everything, as you have tested, with your sign-off.
+<6> look at all your changes including the previous commit.
+<7> amend the previous commit, adding all your new changes,
+using your original message.
+<8> switch to the master branch.
+<9> merge a topic branch into your master branch.
+<10> review commit logs; other forms to limit output can be
+combined and include `-10` (to show up to 10 commits),
+`--until=2005-12-10`, etc.
+<11> view only the changes that touch what's in `curses/`
+directory, since `v2.43` tag.
+
+
+Individual Developer (Participant)[[PARTICIPANT]]
+-------------------------------------------------
+
+A developer working as a participant in a group project needs to
+learn how to communicate with others, and uses these commands in
+addition to the ones needed by a standalone developer.
+
+ * linkgit:git-clone[1] from the upstream to prime your local
+ repository.
+
+ * linkgit:git-pull[1] and linkgit:git-fetch[1] from "origin"
+ to keep up-to-date with the upstream.
+
+ * linkgit:git-push[1] to shared repository, if you adopt CVS
+ style shared repository workflow.
+
+ * linkgit:git-format-patch[1] to prepare e-mail submission, if
+ you adopt Linux kernel-style public forum workflow.
+
+ * linkgit:git-send-email[1] to send your e-mail submission without
+ corruption by your MUA.
+
+ * linkgit:git-request-pull[1] to create a summary of changes
+ for your upstream to pull.
+
+
+Examples
+~~~~~~~~
+
+Clone the upstream and work on it. Feed changes to upstream.::
++
+------------
+$ git clone git://git.kernel.org/pub/scm/.../torvalds/linux-2.6 my2.6
+$ cd my2.6
+$ git checkout -b mine master <1>
+$ edit/compile/test; git commit -a -s <2>
+$ git format-patch master <3>
+$ git send-email --to="person <email@example.com>" 00*.patch <4>
+$ git checkout master <5>
+$ git pull <6>
+$ git log -p ORIG_HEAD.. arch/i386 include/asm-i386 <7>
+$ git ls-remote --heads http://git.kernel.org/.../jgarzik/libata-dev.git <8>
+$ git pull git://git.kernel.org/pub/.../jgarzik/libata-dev.git ALL <9>
+$ git reset --hard ORIG_HEAD <10>
+$ git gc <11>
+------------
++
+<1> checkout a new branch `mine` from master.
+<2> repeat as needed.
+<3> extract patches from your branch, relative to master,
+<4> and email them.
+<5> return to `master`, ready to see what's new
+<6> `git pull` fetches from `origin` by default and merges into the
+current branch.
+<7> immediately after pulling, look at the changes done upstream
+since last time we checked, only in the
+area we are interested in.
+<8> check the branch names in an external repository (if not known).
+<9> fetch from a specific branch `ALL` from a specific repository
+and merge it.
+<10> revert the pull.
+<11> garbage collect leftover objects from reverted pull.
+
+
+Push into another repository.::
++
+------------
+satellite$ git clone mothership:frotz frotz <1>
+satellite$ cd frotz
+satellite$ git config --get-regexp '^(remote|branch)\.' <2>
+remote.origin.url mothership:frotz
+remote.origin.fetch refs/heads/*:refs/remotes/origin/*
+branch.master.remote origin
+branch.master.merge refs/heads/master
+satellite$ git config remote.origin.push \
+ +refs/heads/*:refs/remotes/satellite/* <3>
+satellite$ edit/compile/test/commit
+satellite$ git push origin <4>
+
+mothership$ cd frotz
+mothership$ git checkout master
+mothership$ git merge satellite/master <5>
+------------
++
+<1> mothership machine has a frotz repository under your home
+directory; clone from it to start a repository on the satellite
+machine.
+<2> clone sets these configuration variables by default.
+It arranges `git pull` to fetch and store the branches of mothership
+machine to local `remotes/origin/*` remote-tracking branches.
+<3> arrange `git push` to push all local branches to
+their corresponding branch of the mothership machine.
+<4> push will stash all our work away on `remotes/satellite/*`
+remote-tracking branches on the mothership machine. You could use this
+as a back-up method. Likewise, you can pretend that mothership
+"fetched" from you (useful when access is one sided).
+<5> on mothership machine, merge the work done on the satellite
+machine into the master branch.
+
+Branch off of a specific tag.::
++
+------------
+$ git checkout -b private2.6.14 v2.6.14 <1>
+$ edit/compile/test; git commit -a
+$ git checkout master
+$ git cherry-pick v2.6.14..private2.6.14 <2>
+------------
++
+<1> create a private branch based on a well known (but somewhat behind)
+tag.
+<2> forward port all changes in `private2.6.14` branch to `master` branch
+without a formal "merging". Or longhand +
+`git format-patch -k -m --stdout v2.6.14..private2.6.14 |
+ git am -3 -k`
+
+An alternate participant submission mechanism is using the
+`git request-pull` or pull-request mechanisms (e.g as used on
+GitHub (www.github.com) to notify your upstream of your
+contribution.
+
+Integrator[[INTEGRATOR]]
+------------------------
+
+A fairly central person acting as the integrator in a group
+project receives changes made by others, reviews and integrates
+them and publishes the result for others to use, using these
+commands in addition to the ones needed by participants.
+
+This section can also be used by those who respond to `git
+request-pull` or pull-request on GitHub (www.github.com) to
+integrate the work of others into their history. An sub-area
+lieutenant for a repository will act both as a participant and
+as an integrator.
+
+
+ * linkgit:git-am[1] to apply patches e-mailed in from your
+ contributors.
+
+ * linkgit:git-pull[1] to merge from your trusted lieutenants.
+
+ * linkgit:git-format-patch[1] to prepare and send suggested
+ alternative to contributors.
+
+ * linkgit:git-revert[1] to undo botched commits.
+
+ * linkgit:git-push[1] to publish the bleeding edge.
+
+
+Examples
+~~~~~~~~
+
+A typical integrator's Git day.::
++
+------------
+$ git status <1>
+$ git branch --no-merged master <2>
+$ mailx <3>
+& s 2 3 4 5 ./+to-apply
+& s 7 8 ./+hold-linus
+& q
+$ git checkout -b topic/one master
+$ git am -3 -i -s ./+to-apply <4>
+$ compile/test
+$ git checkout -b hold/linus && git am -3 -i -s ./+hold-linus <5>
+$ git checkout topic/one && git rebase master <6>
+$ git checkout pu && git reset --hard next <7>
+$ git merge topic/one topic/two && git merge hold/linus <8>
+$ git checkout maint
+$ git cherry-pick master~4 <9>
+$ compile/test
+$ git tag -s -m "GIT 0.99.9x" v0.99.9x <10>
+$ git fetch ko && for branch in master maint next pu <11>
+ do
+ git show-branch ko/$branch $branch <12>
+ done
+$ git push --follow-tags ko <13>
+------------
++
+<1> see what you were in the middle of doing, if anything.
+<2> see which branches haven't been merged into `master` yet.
+Likewise for any other integration branches e.g. `maint`, `next`
+and `pu` (potential updates).
+<3> read mails, save ones that are applicable, and save others
+that are not quite ready (other mail readers are available).
+<4> apply them, interactively, with your sign-offs.
+<5> create topic branch as needed and apply, again with sign-offs.
+<6> rebase internal topic branch that has not been merged to the

+<7> restart `pu` every time from the next.
+<8> and bundle topic branches still cooking.
+<9> backport a critical fix.
+<10> create a signed tag.
+<11> make sure master was not accidentally rewound beyond that

++

+(in .git/config)
+[remote "ko"]
+ url = kernel.org:/pub/scm/git/git.git
+ fetch = refs/heads/*:refs/remotes/ko/*
+ push = refs/heads/master
+ push = refs/heads/next
+ push = +refs/heads/pu
+ push = refs/heads/maint
+------------
++
+<12> In the output from `git show-branch`, `master` should have
+everything `ko/master` has, and `next` should have
+everything `ko/next` has, etc.
+<13> push out the bleeding edge, together with new tags that point
+into the pushed history.
+
+
+Repository Administration[[ADMINISTRATION]]
+-------------------------------------------
+
+A repository administrator uses the following tools to set up
+and maintain access to the repository by developers.
+
+ * linkgit:git-daemon[1] to allow anonymous download from
+ repository.
+
+ * linkgit:git-shell[1] can be used as a 'restricted login shell'
+ for shared central repository users.
+
+ * linkgit:git-http-backend[1] provides a server side implementation
+ of Git-over-HTTP ("Smart http") allowing both fetch and push services.
+
+ * linkgit:gitweb[1] provides a web front-end to Git repositories,
+ which can be set-up using the linkgit:git-instaweb[1] script.
+
+link:howto/update-hook-example.html[update hook howto] has a good
+example of managing a shared central repository.
+
+In addition there are a number of other widely deployed hosting, browsing
+and reviewing solutions such as:
+
+ * gitolite, gerrit code review, cgit and others.
+
+Examples
+~~~~~~~~
+We assume the following in /etc/services::
++
+------------
+$ grep 9418 /etc/services
+git 9418/tcp # Git Version Control System
+------------
+
+Run git-daemon to serve /pub/scm from inetd.::
++
+------------
+$ grep git /etc/inetd.conf
+git stream tcp nowait nobody \
+ /usr/bin/git-daemon git-daemon --inetd --export-all /pub/scm
+------------
++
+The actual configuration line should be on one line.
+
+Run git-daemon to serve /pub/scm from xinetd.::
++
+------------
+$ cat /etc/xinetd.d/git-daemon
+# default: off
+# description: The Git server offers access to Git repositories
+service git
+{
+ disable = no
+ type = UNLISTED
+ port = 9418
+ socket_type = stream
+ wait = no
+ user = nobody
+ server = /usr/bin/git-daemon
+ server_args = --inetd --export-all --base-path=/pub/scm
+ log_on_failure += USERID
+}
+------------
++
+Check your xinetd(8) documentation and setup, this is from a Fedora system.
+Others might be different.
+
+Give push/pull only access to developers using git-over-ssh.::
+
+e.g. those using:
+`$ git push/pull ssh://host.xz/pub/scm/project`
++
+------------
+$ grep git /etc/passwd <1>
+alice:x:1000:1000::/home/alice:/usr/bin/git-shell
+bob:x:1001:1001::/home/bob:/usr/bin/git-shell
+cindy:x:1002:1002::/home/cindy:/usr/bin/git-shell
+david:x:1003:1003::/home/david:/usr/bin/git-shell
+$ grep git /etc/shells <2>
+/usr/bin/git-shell
+------------
++
+<1> log-in shell is set to /usr/bin/git-shell, which does not
+allow anything but `git push` and `git pull`. The users require
+ssh access to the machine.
+<2> in many distributions /etc/shells needs to list what is used
+as the login shell.
+
+CVS-style shared repository.::
++
+------------
+$ grep git /etc/group <1>
+git:x:9418:alice,bob,cindy,david
+$ cd /home/devo.git
+$ ls -l <2>
+ lrwxrwxrwx 1 david git 17 Dec 4 22:40 HEAD -> refs/heads/master

+------------
++
+<1> place the developers into the same git group.

--ignore-missing::
Upon seeing an invalid object name in the input, pretend as if

------------
You are responsible for updating the `nr` variable.
+
+If you need to specify the number of elements to allocate explicitly
+then use the macro `REALLOC_ARRAY(item, alloc)` instead of `ALLOC_GROW`.
`git_config_from_file`. This takes the same callback and data parameters
as `git_config`.
+Querying For Specific Variables
+-------------------------------
+
+For programs wanting to query for specific variables in a non-callback
+manner, the config API provides two functions `git_config_get_value`
+and `git_config_get_value_multi`. They both read values from an internal
+cache generated previously from reading the config files.
+
+`int git_config_get_value(const char *key, const char **value)`::
+
+ Finds the highest-priority value for the configuration variable `key`,
+ stores the pointer to it in `value` and returns 0. When the
+ configuration variable `key` is not found, returns 1 without touching
+ `value`. The caller should not free or modify `value`, as it is owned
+ by the cache.
+
+`const struct string_list *git_config_get_value_multi(const char *key)`::
+
+ Finds and returns the value list, sorted in order of increasing priority
+ for the configuration variable `key`. When the configuration variable
+ `key` is not found, returns NULL. The caller should not free or modify
+ the returned pointer, as it is owned by the cache.
+
+`void git_config_clear(void)`::
+
+ Resets and invalidates the config cache.
+
+The config API also provides type specific API functions which do conversion
+as well as retrieval for the queried variable, including:
+
+`int git_config_get_int(const char *key, int *dest)`::
+
+ Finds and parses the value to an integer for the configuration variable
+ `key`. Dies on error; otherwise, stores the value of the parsed integer in
+ `dest` and returns 0. When the configuration variable `key` is not found,
+ returns 1 without touching `dest`.
+
+`int git_config_get_ulong(const char *key, unsigned long *dest)`::
+
+ Similar to `git_config_get_int` but for unsigned longs.
+
+`int git_config_get_bool(const char *key, int *dest)`::
+
+ Finds and parses the value into a boolean value, for the configuration
+ variable `key` respecting keywords like "true" and "false". Integer
+ values are converted into true/false values (when they are non-zero or
+ zero, respectively). Other values cause a die(). If parsing is successful,
+ stores the value of the parsed result in `dest` and returns 0. When the
+ configuration variable `key` is not found, returns 1 without touching
+ `dest`.
+
+`int git_config_get_bool_or_int(const char *key, int *is_bool, int *dest)`::
+
+ Similar to `git_config_get_bool`, except that integers are copied as-is,
+ and `is_bool` flag is unset.
+
+`int git_config_get_maybe_bool(const char *key, int *dest)`::
+
+ Similar to `git_config_get_bool`, except that it returns -1 on error
+ rather than dying.
+
+`int git_config_get_string_const(const char *key, const char **dest)`::
+
+ Allocates and copies the retrieved string into the `dest` parameter for
+ the configuration variable `key`; if NULL string is given, prints an
+ error message and returns -1. When the configuration variable `key` is
+ not found, returns 1 without touching `dest`.
+
+`int git_config_get_string(const char *key, char **dest)`::
+
+ Similar to `git_config_get_string_const`, except that retrieved value
+ copied into the `dest` parameter is a mutable string.
+
+`int git_config_get_pathname(const char *key, const char **dest)`::
+
+ Similar to `git_config_get_string`, but expands `~` or `~user` into
+ the user's home directory when found at the beginning of the path.
+
+`git_die_config(const char *key, const char *err, ...)`::
+
+ First prints the error message specified by the caller in `err` and then
+ dies printing the line number and the file name of the highest priority
+ value for the configuration variable `key`.
+
+`void git_die_config_linenr(const char *key, const char *filename, int linenr)`::
+
+ Helper function which formats the die error message according to the
+ parameters entered. Used by `git_die_config()`. It can be used by callers
+ handling `git_config_get_value_multi()` to print the correct error message
+ for the desired value.
+
+See test-config.c for usage examples.
+
Value Parsing Helpers
---------------------
`git_config` respects includes automatically. The lower-level
`git_config_from_file` does not.
+Custom Configsets
+-----------------
+
+A `config_set` can be used to construct an in-memory cache for
+config-like files that the caller specifies (i.e., files like `.gitmodules`,
+`~/.gitconfig` etc.). For example,
+
+---------------------------------------
+struct config_set gm_config;
+git_configset_init(&gm_config);
+int b;
+/* we add config files to the config_set */
+git_configset_add_file(&gm_config, ".gitmodules");
+git_configset_add_file(&gm_config, ".gitmodules_alt");
+
+if (!git_configset_get_bool(gm_config, "submodule.frotz.ignore", &b)) {
+ /* hack hack hack */
+}
+
+/* when we are done with the configset */
+git_configset_clear(&gm_config);
+----------------------------------------
+
+Configset API provides functions for the above mentioned work flow, including:
+
+`void git_configset_init(struct config_set *cs)`::
+
+ Initializes the config_set `cs`.
+
+`int git_configset_add_file(struct config_set *cs, const char *filename)`::
+
+ Parses the file and adds the variable-value pairs to the `config_set`,
+ dies if there is an error in parsing the file. Returns 0 on success, or
+ -1 if the file does not exist or is inaccessible. The user has to decide
+ if he wants to free the incomplete configset or continue using it when
+ the function returns -1.
+
+`int git_configset_get_value(struct config_set *cs, const char *key, const char **value)`::
+
+ Finds the highest-priority value for the configuration variable `key`
+ and config set `cs`, stores the pointer to it in `value` and returns 0.
+ When the configuration variable `key` is not found, returns 1 without
+ touching `value`. The caller should not free or modify `value`, as it
+ is owned by the cache.
+
+`const struct string_list *git_configset_get_value_multi(struct config_set *cs, const char *key)`::
+
+ Finds and returns the value list, sorted in order of increasing priority
+ for the configuration variable `key` and config set `cs`. When the
+ configuration variable `key` is not found, returns NULL. The caller
+ should not free or modify the returned pointer, as it is owned by the cache.
+
+`void git_configset_clear(struct config_set *cs)`::
+
+ Clears `config_set` structure, removes all saved variable-value pairs.
+
+In addition to above functions, the `config_set` API provides type specific
+functions in the vein of `git_config_get_int` and family but with an extra
+parameter, pointer to struct `config_set`.
+They all behave similarly to the `git_config_get*()` family described in
+"Querying For Specific Variables" above.
+
Writing Config Files
--------------------
The lockfile API serves two purposes:
-* Mutual exclusion. When we write out a new index file, first
- we create a new file `$GIT_DIR/index.lock`, write the new
- contents into it, and rename it to the final destination
- `$GIT_DIR/index`. We try to create the `$GIT_DIR/index.lock`
- file with O_EXCL so that we can notice and fail when somebody
- else is already trying to update the index file.
-
-* Automatic cruft removal. After we create the "lock" file, we
- may decide to `die()`, and we would want to make sure that we
- remove the file that has not been committed to its final
- destination. This is done by remembering the lockfiles we
- created in a linked list and cleaning them up from an
- `atexit(3)` handler. Outstanding lockfiles are also removed
- when the program dies on a signal.
+* Mutual exclusion and atomic file updates. When we want to change a
+ file, we create a lockfile `<filename>.lock`, write the new file
+ contents into it, and then rename the lockfile to its final
+ destination `<filename>`. We create the `<filename>.lock` file with
+ `O_CREAT|O_EXCL` so that we can notice and fail if somebody else has
+ already locked the file, then atomically rename the lockfile to its
+ final destination to commit the changes and unlock the file.
+
+* Automatic cruft removal. If the program exits after we lock a file
+ but before the changes have been committed, we want to make sure
+ that we remove the lockfile. This is done by remembering the
+ lockfiles we have created in a linked list and setting up an
+ `atexit(3)` handler and a signal handler that clean up the
+ lockfiles. This mechanism ensures that outstanding lockfiles are
+ cleaned up if the program exits (including when `die()` is called)
+ or if the program dies on a signal.
+
+Please note that lockfiles only block other writers. Readers do not
+block, but they are guaranteed to see either the old contents of the
+file or the new contents of the file (assuming that the filesystem
+implements `rename(2)` atomically).
+
+
+Calling sequence
+----------------
+
+The caller:
+
+* Allocates a `struct lock_file` either as a static variable or on the
+ heap, initialized to zeros. Once you use the structure to call the
+ `hold_lock_file_*` family of functions, it belongs to the lockfile
+ subsystem and its storage must remain valid throughout the life of
+ the program (i.e. you cannot use an on-stack variable to hold this
+ structure).
+
+* Attempts to create a lockfile by passing that variable and the path
+ of the final destination (e.g. `$GIT_DIR/index`) to
+ `hold_lock_file_for_update` or `hold_lock_file_for_append`.
+
+* Writes new content for the destination file by either:
+
+ * writing to the file descriptor returned by the `hold_lock_file_*`
+ functions (also available via `lock->fd`).
+
+ * calling `fdopen_lock_file` to get a `FILE` pointer for the open
+ file and writing to the file using stdio.
+
+When finished writing, the caller can:
+
+* Close the file descriptor and rename the lockfile to its final
+ destination by calling `commit_lock_file` or `commit_lock_file_to`.
+
+* Close the file descriptor and remove the lockfile by calling
+ `rollback_lock_file`.
+
+* Close the file descriptor without removing or renaming the lockfile
+ by calling `close_lock_file`, and later call `commit_lock_file`,
+ `commit_lock_file_to`, `rollback_lock_file`, or `reopen_lock_file`.
+
+Even after the lockfile is committed or rolled back, the `lock_file`
+object must not be freed or altered by the caller. However, it may be
+reused; just pass it to another call of `hold_lock_file_for_update` or
+`hold_lock_file_for_append`.
+
+If the program exits before you have called one of `commit_lock_file`,
+`commit_lock_file_to`, `rollback_lock_file`, or `close_lock_file`, an
+`atexit(3)` handler will close and remove the lockfile, rolling back
+any uncommitted changes.
+
+If you need to close the file descriptor you obtained from a
+`hold_lock_file_*` function yourself, do so by calling
+`close_lock_file`. You should never call `close(2)` or `fclose(3)`
+yourself! Otherwise the `struct lock_file` structure would still think
+that the file descriptor needs to be closed, and a commit or rollback
+would result in duplicate calls to `close(2)`. Worse yet, if you close
+and then later open another file descriptor for a completely different
+purpose, then a commit or rollback might close that unrelated file
+descriptor.
+
+
+Error handling
+--------------
+
+The `hold_lock_file_*` functions return a file descriptor on success
+or -1 on failure (unless `LOCK_DIE_ON_ERROR` is used; see below). On
+errors, `errno` describes the reason for failure. Errors can be
+reported by passing `errno` to one of the following helper functions:
+
+unable_to_lock_message::
+
+ Append an appropriate error message to a `strbuf`.
+
+unable_to_lock_error::
+
+ Emit an appropriate error message using `error()`.
+
+unable_to_lock_die::
+
+ Emit an appropriate error message and `die()`.
+
+Similarly, `commit_lock_file`, `commit_lock_file_to`, and
+`close_lock_file` return 0 on success. On failure they set `errno`
+appropriately, do their best to roll back the lockfile, and return -1.
+
+
+Flags
+-----
+
+The following flags can be passed to `hold_lock_file_for_update` or
+`hold_lock_file_for_append`:
+
+LOCK_NO_DEREF::
+
+ Usually symbolic links in the destination path are resolved
+ and the lockfile is created by adding ".lock" to the resolved
+ path. If `LOCK_NO_DEREF` is set, then the lockfile is created
+ by adding ".lock" to the path argument itself. This option is
+ used, for example, when locking a symbolic reference, which
+ for backwards-compatibility reasons can be a symbolic link
+ containing the name of the referred-to-reference.
+
+LOCK_DIE_ON_ERROR::
+
+ If a lock is already taken for the file, `die()` with an error
+ message. If this option is not specified, trying to lock a
+ file that is already locked returns -1 to the caller.
The functions
hold_lock_file_for_update::
- Take a pointer to `struct lock_file`, the filename of
- the final destination (e.g. `$GIT_DIR/index`) and a flag
- `die_on_error`. Attempt to create a lockfile for the
- destination and return the file descriptor for writing
- to the file. If `die_on_error` flag is true, it dies if
- a lock is already taken for the file; otherwise it
- returns a negative integer to the caller on failure.
+ Take a pointer to `struct lock_file`, the path of the file to
+ be locked (e.g. `$GIT_DIR/index`) and a flags argument (see
+ above). Attempt to create a lockfile for the destination and
+ return the file descriptor for writing to the file.
+
+hold_lock_file_for_append::
+
+ Like `hold_lock_file_for_update`, but before returning copy
+ the existing contents of the file (if any) to the lockfile and
+ position its write pointer at the end of the file.
+
+fdopen_lock_file::
+
+ Associate a stdio stream with the lockfile. Return NULL
+ (*without* rolling back the lockfile) on error. The stream is
+ closed automatically when `close_lock_file` is called or when
+ the file is committed or rolled back.
+
+get_locked_file_path::
+
+ Return the path of the file that is locked by the specified
+ lock_file object. The caller must free the memory.
commit_lock_file::
- Take a pointer to the `struct lock_file` initialized
- with an earlier call to `hold_lock_file_for_update()`,
- close the file descriptor and rename the lockfile to its
- final destination. Returns 0 upon success, a negative
- value on failure to close(2) or rename(2).
+ Take a pointer to the `struct lock_file` initialized with an
+ earlier call to `hold_lock_file_for_update` or
+ `hold_lock_file_for_append`, close the file descriptor, and
+ rename the lockfile to its final destination. Return 0 upon
+ success. On failure, roll back the lock file and return -1,
+ with `errno` set to the value from the failing call to
+ `close(2)` or `rename(2)`. It is a bug to call
+ `commit_lock_file` for a `lock_file` object that is not
+ currently locked.
+
+commit_lock_file_to::
+
+ Like `commit_lock_file()`, except that it takes an explicit
+ `path` argument to which the lockfile should be renamed. The
+ `path` must be on the same filesystem as the lock file.
rollback_lock_file::
- Take a pointer to the `struct lock_file` initialized
- with an earlier call to `hold_lock_file_for_update()`,
- close the file descriptor and remove the lockfile.
+ Take a pointer to the `struct lock_file` initialized with an
+ earlier call to `hold_lock_file_for_update` or
+ `hold_lock_file_for_append`, close the file descriptor and
+ remove the lockfile. It is a NOOP to call
+ `rollback_lock_file()` for a `lock_file` object that has
+ already been committed or rolled back.
close_lock_file::
- Take a pointer to the `struct lock_file` initialized
- with an earlier call to `hold_lock_file_for_update()`,
- and close the file descriptor. Returns 0 upon success,
- a negative value on failure to close(2).
-
-Because the structure is used in an `atexit(3)` handler, its
-storage has to stay throughout the life of the program. It
-cannot be an auto variable allocated on the stack.
-
-Call `commit_lock_file()` or `rollback_lock_file()` when you are
-done writing to the file descriptor. If you do not call either
-and simply `exit(3)` from the program, an `atexit(3)` handler
-will close and remove the lockfile.
-
-If you need to close the file descriptor you obtained from
-`hold_lock_file_for_update` function yourself, do so by calling
-`close_lock_file()`. You should never call `close(2)` yourself!
-Otherwise the `struct
-lock_file` structure still remembers that the file descriptor
-needs to be closed, and a later call to `commit_lock_file()` or
-`rollback_lock_file()` will result in duplicate calls to
-`close(2)`. Worse yet, if you `close(2)`, open another file
-descriptor for completely different purpose, and then call
-`commit_lock_file()` or `rollback_lock_file()`, they may close
-that unrelated file descriptor.
+
+ Take a pointer to the `struct lock_file` initialized with an
+ earlier call to `hold_lock_file_for_update` or
+ `hold_lock_file_for_append`. Close the file descriptor (and
+ the file pointer if it has been opened using
+ `fdopen_lock_file`). Return 0 upon success. On failure to
+ `close(2)`, return a negative value and roll back the lock
+ file. Usually `commit_lock_file`, `commit_lock_file_to`, or
+ `rollback_lock_file` should eventually be called if
+ `close_lock_file` succeeds.
+
+reopen_lock_file::
+
+ Re-open a lockfile that has been closed (using
+ `close_lock_file`) but not yet committed or rolled back. This
+ can be used to implement a sequence of operations like the
+ following:
+
+ * Lock file.
+
+ * Write new contents to lockfile, then `close_lock_file` to
+ cause the contents to be written to disk.
+
+ * Pass the name of the lockfile to another program to allow it
+ (and nobody else) to inspect the contents you wrote, while
+ still holding the lock yourself.
+
+ * `reopen_lock_file` to reopen the lockfile. Make further
+ updates to the contents.
+
+ * `commit_lock_file` to make the final version permanent.
Functions
---------
+`child_process_init`
+
+ Initialize a struct child_process variable.
+
`start_command`::
Start a sub-process. Takes a pointer to a `struct child_process`
The caller:
-1. allocates and clears (memset(&chld, 0, sizeof(chld));) a
- struct child_process variable;
+1. allocates and clears (using child_process_init() or
+ CHILD_PROCESS_INIT) a struct child_process variable;
2. initializes the members;
3. calls start_command();
4. processes the data;
. If the string does not contain '=', it names an environment
variable that will be removed from the child process's environment.
+If the .env member is NULL, `start_command` will point it at the
+.env_array `argv_array` (so you may use one or the other, but not both).
+The memory in .env_array will be cleaned up automatically during
+`finish_command` (or during `start_command` when it is unsuccessful).
+
To specify a new initial working directory for the sub-process,
specify it in the .dir member.
Add a single character to the buffer.
+`strbuf_addchars`::
+
+ Add a character the specified number of times to the buffer.
+
`strbuf_insert`::
Insert data to the given position of the buffer. The remaining contents
use it unless you need the correct position in the file
descriptor.
+`strbuf_getcwd`::
+
+ Set the buffer to the path of the current working directory.
+
+`strbuf_add_absolute_path`
+
+ Add a path to a buffer, converting a relative path to an
+ absolute one in the process. Symbolic links are not
+ resolved.
+
`stripspace`::
Strip whitespace from a buffer. The second parameter controls if
want-list = first-want
*additional-want
- shallow-line = PKT_LINE("shallow" SP obj-id)
+ shallow-line = PKT-LINE("shallow" SP obj-id)

----
If the receiving end does not support delete-refs, the sending end MUST
NOT ask for delete command.
+If the receiving end does not support push-cert, the sending end
+MUST NOT send a push-cert command. When a push-cert command is
+sent, command-list MUST NOT be sent; the commands recorded in the
+push certificate is used instead.
+
The pack-file MUST NOT be sent if the only command used is 'delete'.
A pack-file MUST be sent if either create or update command is used,
it will run any update hooks to make sure that the update is acceptable.
If all of that is fine, the server will then update the references.
+Push Certificate
+----------------
+
+A push certificate begins with a set of header lines. After the
+header and an empty line, the protocol commands follow, one per
+line.
+
+Currently, the following header fields are defined:
+
+`pusher` ident::
+ Identify the GPG key in "Human Readable Name <email@address>"
+ format.
+
+`pushee` url::
+ The repository URL (anonymized, if the URL contains
+ authentication material) the user who ran `git push`
+ intended to push into.
+
+`nonce` nonce::
+ The 'nonce' string the receiving repository asked the
+ pushing user to include in the certificate, to prevent
+ replay attacks.
+
+The GPG signature lines are a detached signature for the contents
+recorded in the push certificate before the signature block begins.
+The detached signature is used to certify that the commands were
+given by the pusher, who must be the signer.
+
Report Status
-------------
and server advertised. As a consequence of these rules, server MUST
NOT advertise capabilities it does not understand.
-The 'report-status', 'delete-refs', and 'quiet' capabilities are sent and
-recognized by the receive-pack (push to server) process.
+The 'report-status', 'delete-refs', 'quiet', and 'push-cert' capabilities
+are sent and recognized by the receive-pack (push to server) process.
The 'ofs-delta' and 'side-band-64k' capabilities are sent and recognized
by both upload-pack and receive-pack protocols. The 'agent' capability
If the upload-pack server advertises this capability, fetch-pack may
send "want" lines with SHA-1s that exist at the server but are not
advertised by upload-pack.
+
+push-cert=<nonce>
+-----------------
+
+The receive-pack server that advertises this capability is willing
+to accept a signed push certificate, and asks the <nonce> to be
+included in the push certificate. A send-pack client MUST NOT
+send a push-cert packet unless the receive-pack server advertises
+this capability.

+ * File write-locks as used by Git.
+ *
+ * For an overview of how to use the lockfile API, please see
+ *
+ * Documentation/technical/api-lockfile.txt
+ *
+ * This module keeps track of all locked files in lock_file_list for
+ * use at cleanup. This list and the lock_file objects that comprise
+ * it must be kept in self-consistent states at all time, because the
+ * program can be interrupted any time by a signal, in which case the
+ * signal handler will walk through the list attempting to clean up
+ * any open lock files.
+ *
+ * A lockfile is owned by the process that created it. The lock_file
+ * object has an "owner" field that records its owner. This field is
+ * used to prevent a forked process from closing a lockfile created by
+ * its parent.
+ *
+ * The possible states of a lock_file object are as follows:
+ *
+ * - Uninitialized. In this state the object's on_list field must be
+ * zero but the rest of its contents need not be initialized. As
+ * soon as the object is used in any way, it is irrevocably
+ * registered in the lock_file_list, and on_list is set.
+ *
+ * - Locked, lockfile open (after hold_lock_file_for_update(),
+ * hold_lock_file_for_append(), or reopen_lock_file()). In this
+ * state:
+ * - the lockfile exists
+ * - active is set
+ * - filename holds the filename of the lockfile
+ * - fd holds a file descriptor open for writing to the lockfile
+ * - fp holds a pointer to an open FILE object if and only if
+ * fdopen_lock_file() has been called on the object
+ * - owner holds the PID of the process that locked the file
+ *
+ * - Locked, lockfile closed (after successful close_lock_file()).
+ * Same as the previous state, except that the lockfile is closed
+ * and fd is -1.
+ *
+ * - Unlocked (after commit_lock_file(), commit_lock_file_to(),
+ * rollback_lock_file(), a failed attempt to lock, or a failed
+ * close_lock_file()). In this state:
+ * - active is unset
+ * - filename is empty (usually, though there are transitory
+ * states in which this condition doesn't hold). Client code should
+ * *not* rely on the filename being empty in this state.
+ * - fd is -1
+ * - the object is left registered in the lock_file_list, and
+ * on_list is set.

+# This test covers the handling of objects which might have old
+# mtimes in the filesystem (because they were used previously)
+# and are just now becoming referenced again.
+#
+# We're going to do two things that are a little bit "fake" to
+# help make our simulation easier:
+#
+# 1. We'll turn off reflogs. You can still run into
+# problems with reflogs on, but your objects
+# don't get pruned until both the reflog expiration
+# has passed on their references, _and_ they are out
+# of prune's expiration period. Dropping reflogs
+# means we only have to deal with one variable in our tests,
+# but the results generalize.
+#
+# 2. We'll use a temporary index file to create our
+# works-in-progress. Most workflows would mention
+# referenced objects in the index, which prune takes
+# into account. However, many operations don't. For
+# example, a partial commit with "git commit foo"
+# will use a temporary index. Or they may not need
+# an index at all (e.g., creating a new commit
+# to refer to an existing tree).
