+Git v2.4.8 Release Notes
+========================
+
+Fixes since v2.4.7
+------------------
+
+ * Abandoning an already applied change in "git rebase -i" with
+ "--continue" left CHERRY_PICK_HEAD and confused later steps.
+
+ * Various fixes around "git am" that applies a patch to a history
+ that is not there yet.
+
+ * "git for-each-ref" reported "missing object" for 0{40} when it
+ encounters a broken ref. The lack of object whose name is 0{40} is
+ not the problem; the ref being broken is.
+
+ * "git commit --cleanup=scissors" was not careful enough to protect
+ against getting fooled by a line that looked like scissors.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+Git v2.5.1 Release Notes
+========================
+
+Fixes since v2.5
+----------------
+
+ * Running an aliased command from a subdirectory when the .git thing
+ in the working tree is a gitfile pointing elsewhere did not work.
+
+ * Often a fast-import stream builds a new commit on top of the
+ previous commit it built, and it often unconditionally emits a
+ "from" command to specify the first parent, which can be omitted in
+ such a case. This caused fast-import to forget the tree of the
+ previous commit and then re-read it from scratch, which was
+ inefficient. Optimize for this common case.
+
+ * The "rev-parse --parseopt" mode parsed the option specification
+ and the argument hint in a strange way to allow '=' and other
+ special characters in the option name while forbidding them from
+ the argument hint. This made it impossible to define an option
+ like "--pair <key>=<value>" with "pair=key=value" specification,
+ which instead would have defined a "--pair=key <value>" option.
+
+ * A "rebase" replays changes of the local branch on top of something
+ else, as such they are placed in stage #3 and referred to as
+ "theirs", while the changes in the new base, typically a foreign
+ work, are placed in stage #2 and referred to as "ours". Clarify
+ the "checkout --ours/--theirs".
+
+ * An experimental "untracked cache" feature used uname(2) in a
+ slightly unportable way.
+
+ * "sparse checkout" misbehaved for a path that is excluded from the
+ checkout when switching between branches that differ at the path.
+
+ * The low-level "git send-pack" did not honor 'user.signingkey'
+ configuration variable when sending a signed-push.
+
+ * An attempt to delete a ref by pushing into a repository whose HEAD
+ symbolic reference points at an unborn branch that cannot be
+ created due to ref D/F conflict (e.g. refs/heads/a/b exists, HEAD
+ points at refs/heads/a) failed.
+
+ * "git subtree" (in contrib/) depended on "git log" output to be
+ stable, which was a no-no. Apply a workaround to force a
+ particular date format.
+
+ * "git clone $URL" in recent releases of Git contains a regression in
+ the code that invents a new repository name incorrectly based on
+ the $URL. This has been corrected.
+ (merge db2e220 jk/guess-repo-name-regression-fix later to maint).
+
+ * Running tests with the "-x" option to make them verbose had some
+ unpleasant interactions with other features of the test suite.
+ (merge 9b5fe78 jk/test-with-x later to maint).
+
+ * "git pull" in recent releases of Git has a regression in the code
+ that allows custom path to the --upload-pack=<program>. This has
+ been corrected.
+
+ * pipe() emulation used in Git for Windows looked at a wrong variable
+ when checking for an error from an _open_osfhandle() call.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+Git 2.6 Release Notes
+=====================
+
+Updates since v2.5
+------------------
+
+UI, Workflows & Features
+
+ * An asterisk as a substring (as opposed to the entirety) of a path
+ component for both side of a refspec, e.g.
+ "refs/heads/o*:refs/remotes/heads/i*", is now allowed.
+
+ * New userdiff pattern definition for fountain screenwriting markup
+ format has been added.
+
+ * "git log" and friends learned a new "--date=format:..." option to
+ format timestamps using system's strftime(3).
+
+ * "git fast-import" learned to respond to the get-mark command via
+ its cat-blob-fd interface.
+
+ * "git rebase -i" learned "drop commit-object-name subject" command
+ as another way to skip replaying of a commit.
+
+ * A new configuration variable can enable "--follow" automatically
+ when "git log" is run with one pathspec argument.
+
+ * "git status" learned to show a more detailed information regarding
+ the "rebase -i" session in progress.
+
+ * "git cat-file" learned "--batch-all-objects" option to enumerate all
+ available objects in the repository more quickly than "rev-list
+ --all --objects" (the output includes unreachable objects, though).
+
+ * "git fsck" learned to ignore errors on a set of known-to-be-bad
+ objects, and also allows the warning levels of various kinds of
+ non-critical breakages to be tweaked.
+
+ * "git rebase -i"'s list of todo is made configurable.
+
+ * "git send-email" now performs alias-expansion on names that are
+ given via --cccmd, etc.
+
+ * An environment variable GIT_REPLACE_REF_BASE tells Git to look into
+ refs hierarchy other than refs/replace/ for the object replacement
+ data.
+
+ * Allow untracked cache (experimental) to be used when sparse
+ checkout (experimental) is also in use.
+
+ * "git pull --rebase" has been taught to pay attention to
+ rebase.autostash configuration.
+
+ * The command-line completion script (in contrib/) has been updated.
+
+ * A negative !ref entry in multi-value transfer.hideRefs
+ configuration can be used to say "don't hide this one".
+
+ * After "git am" without "-3" stops, running "git am -" pays attention
+ to "-3" only for the patch that caused the original invocation
+ to stop.
+
+ * When linked worktree is used, simultaneous "notes merge" instances
+ for the same ref in refs/notes/* are prevented from stomping on
+ each other.
+
+ * "git send-email" learned a new option --smtp-auth to limit the SMTP
+ AUTH mechanisms to be used to a subset of what the system library
+ supports.
+
+ * A new configuration variable http.sslVersion can be used to specify
+ what specific version of SSL/TLS to use to make a connection.
+
+ * "git notes merge" can be told with "--strategy=<how>" option how to
+ automatically handle conflicts; this can now be configured by
+ setting notes.mergeStrategy configuration variable.
+
+ * "git log --cc" did not show any patch, even though most of the time
+ the user meant "git log --cc -p -m" to see patch output for commits
+ with a single parent, and combined diff for merge commits. The
+ command is taught to DWIM "--cc" (without "--raw" and other forms
+ of output specification) to "--cc -p -m".
+
+ * "git config --list" output was hard to parse when values consist of
+ multiple lines. "--name-only" option is added to help this.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * In preparation for allowing different "backends" to store the refs
+ in a way different from the traditional "one ref per file in
+ $GIT_DIR or in a $GIT_DIR/packed-refs file" filesystem storage,
+ direct filesystem access to ref-like things like CHERRY_PICK_HEAD
+ from scripts and programs has been reduced.
+
+ * Computation of untracked status indicator by bash prompt
+ script (in contrib/) has been optimized.
+
+ * Memory use reduction when commit-slab facility is used to annotate
+ sparsely (which is not recommended in the first place).
+
+ * Clean up refs API and make "git clone" less intimate with the
+ implementation detail.
+
+ * "git pull" was reimplemented in C.
+
+ * The packet tracing machinery allows to capture an incoming pack
+ data to a file for debugging.
+
+ * Move machinery to parse human-readable scaled numbers like 1k, 4M,
+ and 2G as an option parameter's value from pack-objects to
+ parse-options API, to make it available to other codepaths.
+
+ * "git verify-tag" and "git verify-commit" have been taught to share
+ more code, and then learned to optionally show the verification
+ message from the underlying GPG implementation.
+
+ * Various enhancements around "git am" reading patches generated by
+ foreign SCM have been made.
+
+ * Ref listing by "git branch -l" and "git tag -l" commands has
+ started to be rebuilt, based on the for-each-ref machinery.
+
+ * The code to perform multi-tree merges has been taught to repopulate
+ the cache-tree upon a successful merge into the index, so that
+ subsequent "diff-index --cached" (hence "status") and "write-tree"
+ (hence "commit") will go faster.
+
+ The same logic in "git checkout" may now be removed, but that is a
+ separate issue.
+
+ * Tests that assume how reflogs are represented on the filesystem too
+ much have been corrected.
+
+ * "git am" has been rewritten in "C".
+
+ * git_path() and mkpath() are handy helper functions but it is easy
+ to misuse, as the callers need to be careful to keep the number of
+ active results below 4. Their uses have been reduced.
+
+ * The "lockfile" API has been rebuilt on top of a new "tempfile" API.
+
+ * To prepare for allowing a different "ref" backend to be plugged in
+ to the system, update_ref()/delete_ref() have been taught about
+ ref-like things like MERGE_HEAD that are per-worktree (they will
+ always be written to the filesystem inside $GIT_DIR).
+
+ * The gitmodules API that is accessed from the C code learned to
+ cache stuff lazily.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.5
+----------------
+
+Unless otherwise noted, all the fixes since v2.5 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git subtree" (in contrib/) depended on "git log" output to be
+ stable, which was a no-no. Apply a workaround to force a
+ particular date format.
+ (merge e7aac44 da/subtree-date-confusion later to maint).
+
+ * An attempt to delete a ref by pushing into a repository whose HEAD
+ symbolic reference points at an unborn branch that cannot be
+ created due to ref D/F conflict (e.g. refs/heads/a/b exists, HEAD
+ points at refs/heads/a) failed.
+ (merge b112b14 jx/do-not-crash-receive-pack-wo-head later to maint).
+
+ * The low-level "git send-pack" did not honor 'user.signingkey'
+ configuration variable when sending a signed-push.
+ (merge d830d39 db/send-pack-user-signingkey later to maint).
+
+ * "sparse checkout" misbehaved for a path that is excluded from the
+ checkout when switching between branches that differ at the path.
+ (merge 7d78241 as/sparse-checkout-removal later to maint).
+
+ * An experimental "untracked cache" feature used uname(2) in a
+ slightly unportable way.
+ (merge 100e433 cb/uname-in-untracked later to maint).
+
+ * A "rebase" replays changes of the local branch on top of something
+ else, as such they are placed in stage #3 and referred to as
+ "theirs", while the changes in the new base, typically a foreign
+ work, are placed in stage #2 and referred to as "ours". Clarify
+ the "checkout --ours/--theirs".
+ (merge f303016 se/doc-checkout-ours-theirs later to maint).
+
+ * The "rev-parse --parseopt" mode parsed the option specification
+ and the argument hint in a strange way to allow '=' and other
+ special characters in the option name while forbidding them from
+ the argument hint. This made it impossible to define an option
+ like "--pair <key>=<value>" with "pair=key=value" specification,
+ which instead would have defined a "--pair=key <value>" option.
+ (merge 2d893df ib/scripted-parse-opt-better-hint-string later to maint).
+
+ * Often a fast-import stream builds a new commit on top of the
+ previous commit it built, and it often unconditionally emits a
+ "from" command to specify the first parent, which can be omitted in
+ such a case. This caused fast-import to forget the tree of the
+ previous commit and then re-read it from scratch, which was
+ inefficient. Optimize for this common case.
+ (merge 0df3245 mh/fast-import-optimize-current-from later to maint).
+
+ * Running an aliased command from a subdirectory when the .git thing
+ in the working tree is a gitfile pointing elsewhere did not work.
+ (merge d95138e nd/export-worktree later to maint).
+
+ * "Is this subdirectory a separate repository that should not be
+ touched?" check "git clean" was inefficient. This was replaced
+ with a more optimized check.
+ (merge 38ae878 ee/clean-remove-dirs later to maint).
+
+ * The "new-worktree-mode" hack in "checkout" that was added in
+ nd/multiple-work-trees topic has been removed by updating the
+ implementation of new "worktree add".
+ (merge 65f9b75 es/worktree-add-cleanup later to maint).
+
+ * Remove remaining cruft from "git checkout --to", which
+ transitioned to "git worktree add".
+ (merge 114ff88 es/worktree-add later to maint).
+
+ * An off-by-one error made "git remote" to mishandle a remote with a
+ single letter nickname.
+ (merge bc598c3 mh/get-remote-group-fix later to maint).
+
+ * "git clone $URL", when cloning from a site whose sole purpose is to
+ host a single repository (hence, no path after <scheme>://<site>/),
+ tried to use the site name as the new repository name, but did not
+ remove username or password when <site> part was of the form
+ <user>@<pass>:<host>. The code is taught to redact these.
+ (merge adef956 ps/guess-repo-name-at-root later to maint).
+
+ * Running tests with the "-x" option to make them verbose had some
+ unpleasant interactions with other features of the test suite.
+ (merge 9b5fe78 jk/test-with-x later to maint).
+
+ * t1509 test that requires a dedicated VM environment had some
+ bitrot, which has been corrected.
+ (merge faacc5a ps/t1509-chroot-test-fixup later to maint).
+
+ * "git pull" in recent releases of Git has a regression in the code
+ that allows custom path to the --upload-pack=<program>. This has
+ been corrected.
+
+ Note that this is irrelevant for 'master' with "git pull" rewritten
+ in C.
+ (merge 22d6857 mm/pull-upload-pack later to maint).
+
+ * When trying to see that an object does not exist, a state errno
+ leaked from our "first try to open a packfile with O_NOATIME and
+ then if it fails retry without it" logic on a system that refuses
+ O_NOATIME. This confused us and caused us to die, saying that the
+ packfile is unreadable, when we should have just reported that the
+ object does not exist in that packfile to the caller.
+ (merge dff6f28 cb/open-noatime-clear-errno later to maint).
+
+ * The codepath to produce error messages had a hard-coded limit to
+ the size of the message, primarily to avoid memory allocation while
+ calling die().
+ (merge f4c3edc jk/long-error-messages later to maint).
+
+ * strbuf_read() used to have one extra iteration (and an unnecessary
+ strbuf_grow() of 8kB), which was eliminated.
+ (merge 3ebbd00 jh/strbuf-read-use-read-in-full later to maint).
+
+ * We rewrote one of the build scripts in Perl but this reimplements
+ in Bourne shell.
+ (merge 82aec45 sg/help-group later to maint).
+
+ * The experimental untracked-cache feature were buggy when paths with
+ a few levels of subdirectories are involved.
+ (merge 73f9145 dt/untracked-subdir later to maint).
+
+ * "interpret-trailers" helper mistook a single-liner log message that
+ has a colon as the end of existing trailer.
+ (merge 6262fe9 cc/trailers-corner-case-fix later to maint).
+
+ * "git describe" without argument defaulted to describe the HEAD
+ commit, but "git describe --contains" didn't. Arguably, in a
+ repository used for active development, such defaulting would not
+ be very useful as the tip of branch is typically not tagged, but it
+ is better to be consistent.
+ (merge 2bd0706 sg/describe-contains later to maint).
+
+ * The client side codepaths in "git push" have been cleaned up
+ and the user can request to perform an optional "signed push",
+ i.e. sign only when the other end accepts signed push.
+ (merge 68c757f db/push-sign-if-asked later to maint).
+
+ * Because the configuration system does not allow "alias.0foo" and
+ "pager.0foo" as the configuration key, the user cannot use '0foo'
+ as a custom command name anyway, but "git 0foo" tried to look these
+ keys up and emitted useless warnings before saying '0foo is not a
+ git command'. These warning messages have been squelched.
+ (merge 9e9de18 jk/fix-alias-pager-config-key-warnings later to maint).
+
+ * "git rev-list" does not take "--notes" option, but did not complain
+ when one is given.
+ (merge 2aea7a5 jk/rev-list-has-no-notes later to maint).
+
+ * Code cleanups and documentation updates.

by giving '--no-keep-cr' from the command line.
See linkgit:git-am[1], linkgit:git-mailsplit[1].
+am.threeWay::
+ By default, `git am` will fail if the patch does not apply cleanly. When
+ set to true, this setting tells `git am` to fall back on 3-way merge if
+ the patch records the identity of blobs it is supposed to apply to and
+ we have those blobs available locally (equivalent to giving the `--3way`
+ option from the command line). Defaults to `false`.
+ See linkgit:git-am[1].
+
apply.ignoreWhitespace::
When set to 'change', tells 'git apply' to ignore changes in
whitespace, in the same way as the '--ignore-space-change'
object to a worktree file upon checkout. See
linkgit:gitattributes[5] for details.
+fsck.<msg-id>::
+ Allows overriding the message type (error, warn or ignore) of a
+ specific message ID such as `missingEmail`.
++
+For convenience, fsck prefixes the error/warning with the message ID,
+e.g. "missingEmail: invalid author/committer line - missing email" means
+that setting `fsck.missingEmail = ignore` will hide that issue.
++
+This feature is intended to support working with legacy repositories
+which cannot be repaired without disruptive changes.
+
+fsck.skipList::
+ The path to a sorted list of object names (i.e. one SHA-1 per
+ line) that are known to be broken in a non-fatal way and should
+ be ignored. This feature is useful when an established project
+ should be accepted despite early commits containing errors that
+ can be safely ignored such as invalid committer email addresses.
+ Note: corrupt objects cannot be skipped with this setting.
+
gc.aggressiveDepth::
The depth parameter used in the delta compression
algorithm used by 'git gc --aggressive'. This defaults
gc.pruneExpire::
When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
Override the grace period with this config variable. The value
- "now" may be used to disable this grace period and always prune
- unreachable objects immediately.
-
-gc.pruneWorktreesExpire::
- When 'git gc' is run, it will call
- 'prune --worktrees --expire 3.months.ago'.
- Override the grace period with this config variable. The value
- "now" may be used to disable the grace period and prune
- $GIT_DIR/worktrees immediately.
+ "now" may be used to disable this grace period and always prune
+ unreachable objects immediately, or "never" may be used to
+ suppress pruning.
+
+gc.worktreePruneExpire::
+ When 'git gc' is run, it calls
+ 'git worktree prune --expire 3.months.ago'.
+ This config variable can be used to set a different grace
+ period. The value "now" may be used to disable the grace
+ period and prune $GIT_DIR/worktrees immediately, or "never"
+ may be used to suppress pruning.
gc.reflogExpire::
gc.<pattern>.reflogExpire::
'git reflog expire' removes reflog entries older than
- this time; defaults to 90 days. With "<pattern>" (e.g.
+ this time; defaults to 90 days. The value "now" expires all
+ entries immediately, and "never" suppresses expiration
+ altogether. With "<pattern>" (e.g.
"refs/stash") in the middle the setting applies only to
the refs that match the <pattern>.
gc.reflogExpireUnreachable::
-gc.<ref>.reflogExpireUnreachable::
+gc.<pattern>.reflogExpireUnreachable::
'git reflog expire' removes reflog entries older than
this time and are not reachable from the current tip;
- defaults to 30 days. With "<pattern>" (e.g. "refs/stash")
+ defaults to 30 days. The value "now" expires all entries
+ immediately, and "never" suppresses expiration altogether.
+ With "<pattern>" (e.g. "refs/stash")
in the middle, the setting applies only to the refs that
match the <pattern>.
If set, store cookies received during requests to the file specified by
http.cookieFile. Has no effect if http.cookieFile is unset.
+http.sslVersion::
+ The SSL version to use when negotiating an SSL connection, if you
+ want to force the default. The available and default version
+ depend on whether libcurl was built against NSS or OpenSSL and the
+ particular configuration of the crypto library in use. Internally
+ this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl
+ documentation for more details on the format of this option and
+ for the ssl version supported. Actually the possible values of
+ this option are:
+
+ - sslv2
+ - sslv3
+ - tlsv1
+ - tlsv1.0
+ - tlsv1.1
+ - tlsv1.2
+
++
+Can be overridden by the 'GIT_SSL_VERSION' environment variable.
+To force git to use libcurl's default ssl version and ignore any
+explicit http.sslversion option, set 'GIT_SSL_VERSION' to the
+empty string.
+
http.sslCipherList::
A list of SSL ciphers to use when negotiating an SSL connection.
The available ciphers depend on whether libcurl was built against
mergetool.prompt::
Prompt before each invocation of the merge resolution program.
+notes.mergeStrategy::
+ Which merge strategy to choose by default when resolving notes
+ conflicts. Must be one of `manual`, `ours`, `theirs`, `union`, or
+ `cat_sort_uniq`. Defaults to `manual`. See "NOTES MERGE STRATEGIES"
+ section of linkgit:git-notes[1] for more information on each strategy.
+
+notes.<name>.mergeStrategy::
+ Which merge strategy to choose when doing a notes merge into
+ refs/notes/<name>. This overrides the more general
+ "notes.mergeStrategy". See the "NOTES MERGE STRATEGIES" section in
+ linkgit:git-notes[1] for more information on the available strategies.
+
notes.displayRef::
The (fully qualified) refname from which to show notes when
showing commit messages. The value of this variable can be set
When copying notes during a rewrite (see the
"notes.rewrite.<command>" option), determines what to do if
the target commit already has a note. Must be one of
- `overwrite`, `concatenate`, or `ignore`. Defaults to
- `concatenate`.
+ `overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
+ Defaults to `concatenate`.
+
This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
environment variable.
may override this configuration at time of push by specifying
'--no-follow-tags'.
+push.gpgSign::
+ May be set to a boolean value, or the string 'if-asked'. A true
+ value causes all pushes to be GPG signed, as if '--signed' is
+ passed to linkgit:git-push[1]. The string 'if-asked' causes
+ pushes to be signed if the server supports it, as if
+ '--signed=if-asked' is passed to 'git push'. A false value may
+ override a value from a lower-priority config file. An explicit
+ command-line flag always overrides this config option.
rebase.stat::
Whether to show a diffstat of what changed upstream since the last
successful rebase might result in non-trivial conflicts.
Defaults to false.
+rebase.missingCommitsCheck::
+ If set to "warn", git rebase -i will print a warning if some
+ commits are removed (e.g. a line was deleted), however the
+ rebase will still proceed. If set to "error", it will print
+ the previous warning and stop the rebase, 'git rebase
+ --edit-todo' can then be used to correct the error. If set to
+ "ignore", no checking is done.
+ To drop a commit without warning or error, use the `drop`
+ command in the todo-list.
+ Defaults to "ignore".
+
+rebase.instructionFormat
+ A format string, as specified in linkgit:git-log[1], to be used for
+ the instruction list during an interactive rebase. The format will automatically
+ have the long commit hash prepended to the format.
+
receive.advertiseAtomic::
By default, git-receive-pack will advertise the atomic push
capability to its clients. If you don't want to this capability
Defaults to false. If not set, the value of `transfer.fsckObjects`
is used instead.
+receive.fsck.<msg-id>::
+ When `receive.fsckObjects` is set to true, errors can be switched
+ to warnings and vice versa by configuring the `receive.fsck.<msg-id>`
+ setting where the `<msg-id>` is the fsck message ID and the value
+ is one of `error`, `warn` or `ignore`. For convenience, fsck prefixes
+ the error/warning with the message ID, e.g. "missingEmail: invalid
+ author/committer line - missing email" means that setting
+ `receive.fsck.missingEmail = ignore` will hide that issue.
++
+This feature is intended to support working with legacy repositories
+which would not pass pushing when `receive.fsckObjects = true`, allowing
+the host to accept repositories with certain known issues but still catch
+other issues.
+
+receive.fsck.skipList::
+ The path to a sorted list of object names (i.e. one SHA-1 per
+ line) that are known to be broken in a non-fatal way and should
+ be ignored. This feature is useful when an established project
+ should be accepted despite early commits containing errors that
+ can be safely ignored such as invalid committer email addresses.
+ Note: corrupt objects cannot be skipped with this setting.
+
receive.unpackLimit::
If the number of objects received in a push is below this
limit then the objects will be unpacked into loose object
set when initializing a shared repository.
receive.hideRefs::
- String(s) `receive-pack` uses to decide which refs to omit
- from its initial advertisement. Use more than one
- definitions to specify multiple prefix strings. A ref that

NAME
----
-git-bisect - Find by binary search the change that introduced a bug
+git-bisect - Use binary search to find the commit that introduced a bug
SYNOPSIS
The command takes various subcommands, and different options depending
on the subcommand:
- git bisect help
git bisect start [--no-checkout] [<bad> [<good>...]] [--] [<paths>...]
git bisect bad [<rev>]
git bisect good [<rev>...]
git bisect replay <logfile>
git bisect log
git bisect run <cmd>...
+ git bisect help
-This command uses 'git rev-list --bisect' to help drive the
-binary search process to find which change introduced a bug, given an
-old "good" commit object name and a later "bad" commit object name.
-
-Getting help
-~~~~~~~~~~~~
-
-Use "git bisect" to get a short usage description, and "git bisect
-help" or "git bisect -h" to get a long usage description.
+This command uses a binary search algorithm to find which commit in
+your project's history introduced a bug. You use it by first telling
+it a "bad" commit that is known to contain the bug, and a "good"
+commit that is known to be before the bug was introduced. Then `git
+bisect` picks a commit between those two endpoints and asks you
+whether the selected commit is "good" or "bad". It continues narrowing
+down the range until it finds the exact commit that introduced the
+change.
Basic bisect commands: start, bad, good
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Using the Linux kernel tree as an example, basic use of the bisect
-command is as follows:
+As an example, suppose you are trying to find the commit that broke a
+feature that was known to work in version `v2.6.13-rc2` of your
+project. You start a bisect session as follows:
------------------------------------------------
$ git bisect start
$ git bisect bad # Current version is bad
-$ git bisect good v2.6.13-rc2 # v2.6.13-rc2 was the last version
- # tested that was good
+$ git bisect good v2.6.13-rc2 # v2.6.13-rc2 is known to be good
------------------------------------------------
-When you have specified at least one bad and one good version, the
-command bisects the revision tree and outputs something similar to
-the following:
+Once you have specified at least one bad and one good commit, `git
+bisect` selects a commit in the middle of that range of history,
+checks it out, and outputs something similar to the following:
------------------------------------------------
-Bisecting: 675 revisions left to test after this
+Bisecting: 675 revisions left to test after this (roughly 10 steps)
------------------------------------------------
-The state in the middle of the set of revisions is then checked out.
-You would now compile that kernel and boot it. If the booted kernel
-works correctly, you would then issue the following command:
+You should now compile the checked-out version and test it. If that
+version works correctly, type
------------------------------------------------
-$ git bisect good # this one is good
+$ git bisect good
------------------------------------------------
-The output of this command would be something similar to the following:
+If that version is broken, type
------------------------------------------------
-Bisecting: 337 revisions left to test after this
+$ git bisect bad
------------------------------------------------
-You keep repeating this process, compiling the tree, testing it, and
-depending on whether it is good or bad issuing the command "git bisect good"
-or "git bisect bad" to ask for the next bisection.
+Then `git bisect` will respond with something like
+
+------------------------------------------------
+Bisecting: 337 revisions left to test after this (roughly 9 steps)
+------------------------------------------------
+
+Keep repeating the process: compile the tree, test it, and depending
+on whether it is good or bad run `git bisect good` or `git bisect bad`
+to ask for the next commit that needs testing.
+
+Eventually there will be no more revisions left to inspect, and the
+command will print out a description of the first bad commit. The
+reference `refs/bisect/bad` will be left pointing at that commit.
-Eventually there will be no more revisions left to bisect, and you
-will have been left with the first bad kernel revision in "refs/bisect/bad".
Bisect reset
~~~~~~~~~~~~
After a bisect session, to clean up the bisection state and return to
-the original HEAD (i.e., to quit bisecting), issue the following command:
+the original HEAD, issue the following command:
------------------------------------------------
$ git bisect reset
$ git bisect reset <commit>
------------------------------------------------
-For example, `git bisect reset HEAD` will leave you on the current
-bisection commit and avoid switching commits at all, while `git bisect
-reset bisect/bad` will check out the first bad revision.
+For example, `git bisect reset bisect/bad` will check out the first
+bad revision, while `git bisect reset HEAD` will leave you on the
+current bisection commit and avoid switching commits at all.

Avoiding testing a commit
~~~~~~~~~~~~~~~~~~~~~~~~~
-If, in the middle of a bisect session, you know that the next suggested
-revision is not a good one to test (e.g. the change the commit
-introduces is known not to work in your environment and you know it
-does not have anything to do with the bug you are chasing), you may
-want to find a nearby commit and try that instead.
+If, in the middle of a bisect session, you know that the suggested
+revision is not a good one to test (e.g. it fails to build and you
+know that the failure does not have anything to do with the bug you
+are chasing), you can manually select a nearby commit and test that
+one instead.
For example:
------------
$ git bisect good/bad # previous round was good or bad.
-Bisecting: 337 revisions left to test after this
+Bisecting: 337 revisions left to test after this (roughly 9 steps)
$ git bisect visualize # oops, that is uninteresting.
$ git reset --hard HEAD~3 # try 3 revisions before what
# was suggested
Bisect skip
~~~~~~~~~~~~
-Instead of choosing by yourself a nearby commit, you can ask Git
-to do it for you by issuing the command:
+Instead of choosing a nearby commit by yourself, you can ask Git to do
+it for you by issuing the command:
------------
$ git bisect skip # Current version cannot be tested
------------
-But Git may eventually be unable to tell the first bad commit among
-a bad commit and one or more skipped commits.
+However, if you skip a commit adjacent to the one you are looking for,
+Git will be unable to tell exactly which of those commits was the
+first bad one.
-You can even skip a range of commits, instead of just one commit,
-using the "'<commit1>'..'<commit2>'" notation. For example:
+You can also skip a range of commits, instead of just one commit,
+using range notation. For example:
------------
$ git bisect skip v2.5..v2.6
$ git bisect skip v2.5 v2.5..v2.6
------------
-This tells the bisect process that the commits between `v2.5` included
-and `v2.6` included should be skipped.
+This tells the bisect process that the commits between `v2.5` and
+`v2.6` (inclusive) should be skipped.
Cutting down bisection by giving more parameters to bisect start
$ git bisect run my_script arguments
------------
-Note that the script (`my_script` in the above example) should
-exit with code 0 if the current source code is good, and exit with a
-code between 1 and 127 (inclusive), except 125, if the current
-source code is bad.
+Note that the script (`my_script` in the above example) should exit
+with code 0 if the current source code is good/old, and exit with a
+code between 1 and 127 (inclusive), except 125, if the current source
+code is bad/new.
Any other exit code will abort the bisect process. It should be noted
-that a program that terminates via "exit(-1)" leaves $? = 255, (see the
-exit(3) manual page), as the value is chopped with "& 0377".
+that a program that terminates via `exit(-1)` leaves $? = 255, (see the
+exit(3) manual page), as the value is chopped with `& 0377`.
The special exit code 125 should be used when the current source code
cannot be tested. If the script exits with this code, the current
are used by POSIX shells to signal specific error status (127 is for
command not found, 126 is for command found but not executable---these
details do not matter, as they are normal errors in the script, as far as

--------
not be combined with any other options or arguments. See the
section `BATCH OUTPUT` below for details.
+--batch-all-objects::
+ Instead of reading a list of objects on stdin, perform the
+ requested batch operation on all objects in the repository and
+ any alternate object stores (not just reachable objects).
+ Requires `--batch` or `--batch-check` be specified. Note that
+ the objects are visited in order sorted by their hashes.
+
+--buffer::
+ Normally batch output is flushed after each object is output, so
+ that a process can interactively read and write from
+ `cat-file`. With this option, the output uses normal stdio
+ buffering; this is much more efficient when invoking
+ `--batch-check` on a large number of objects.
+
--allow-unknown-type::
Allow -s or -t to query broken/corrupt objects of unknown type.
Interpret <refname> as a reference name pattern for a refspec
(as used with remote repositories). If this option is
enabled, <refname> is allowed to contain a single `*`
- in place of a one full pathname component (e.g.,
- `foo/*/bar` but not `foo/bar*`).
+ in the refspec (e.g., `foo/bar*/baz` or `foo/bar*baz/`
+ but not `foo/bar*/baz*`).
--normalize::
Normalize 'refname' by removing any leading slash (`/`)
--theirs::
When checking out paths from the index, check out stage #2
('ours') or #3 ('theirs') for unmerged paths.
++
+Note that during `git rebase` and `git pull --rebase`, 'ours' and
+'theirs' may appear swapped; `--ours` gives the version from the
+branch the changes are rebased onto, while `--theirs` gives the
+version from the branch that holds your work that is being rebased.
++
+This is because `rebase` is used in a workflow that treats the
+history at the remote as the shared canonical one, and treats the
+work done on the branch you are rebasing as the third-party work to
+be integrated, and you are temporarily assuming the role of the
+keeper of the canonical history during the rebase. As the keeper of
+the canonical history, you need to view the history from the remote
+as `ours` (i.e. "our shared canonical history"), while what you did
+on your side branch as `theirs` (i.e. "one contributor's work on top
+of it").

-========================
+Git Tools
+=========
+When Git was young, people looking for third-party Git-related tools came
+to the Git project itself to find them, thus a list of such tools was
+maintained here. These days, however, search engines fill that role much
+more efficiently, so this manually-maintained list has been retired.
-Introduction
-------------
-
-Apart from Git contrib/ area there are some others third-party tools
-you may want to look.
-
-This document presents a brief summary of each tool and the corresponding
-link.
-
-
-Alternative/Augmentative Porcelains
------------------------------------
-
- - *Cogito* (http://www.kernel.org/pub/software/scm/cogito/)
-
- Cogito is a version control system layered on top of the Git tree history
- storage system. It aims at seamless user interface and ease of use,
- providing generally smoother user experience than the "raw" Core Git
- itself and indeed many other version control systems.
-
- Cogito is no longer maintained as most of its functionality
- is now in core Git.
-
-
- - *pg* (http://www.spearce.org/category/projects/scm/pg/)
-
- pg is a shell script wrapper around Git to help the user manage a set of
- patches to files. pg is somewhat like quilt or StGit, but it does have a
- slightly different feature set.
-
-
- - *StGit* (http://www.procode.org/stgit/)
-
- Stacked Git provides a quilt-like patch management functionality in the
- Git environment. You can easily manage your patches in the scope of Git
- until they get merged upstream.
-
-
-History Viewers
----------------
-
- - *gitk* (shipped with git-core)
-
- gitk is a simple Tk GUI for browsing history of Git repositories easily.
-
-

-
- gitview is a GTK based repository browser for Git

- - *gitweb* (shipped with git-core)
-
- Gitweb provides full-fledged web interface for Git repositories.
-
-
- - *qgit* (http://digilander.libero.it/mcostalba/)
-
- QGit is a git/StGit GUI viewer built on Qt/C++. QGit could be used
- to browse history and directory tree, view annotated files, commit
- changes cherry picking single files or applying patches.
- Currently it is the fastest and most feature rich among the Git
- viewers and commit tools.
-
- - *tig* (http://jonas.nitro.dk/tig/)
-
- tig by Jonas Fonseca is a simple Git repository browser
- written using ncurses. Basically, it just acts as a front-end
- for git-log and git-show/git-diff. Additionally, you can also
- use it as a pager for Git commands.
-
-
-Foreign SCM interface
----------------------
-
- - *git-svn* (shipped with git-core)
-
- git-svn is a simple conduit for changesets between a single Subversion
- branch and Git.
-
-
- - *quilt2git / git2quilt* (http://home-tj.org/wiki/index.php/Misc)
-
- These utilities convert patch series in a quilt repository and commit
- series in Git back and forth.
-
-
- - *hg-to-git* (contrib/)
-
- hg-to-git converts a Mercurial repository into a Git one, and
- preserves the full branch history in the process. hg-to-git can
- also be used in an incremental way to keep the Git repository
- in sync with the master Mercurial repository.

+ `CHERRY_PICK_HEAD` are examples. Unlike
+ <<def_per_worktree_ref,per-worktree refs>>, these files cannot
+ be symbolic refs, and never have reflogs. They also cannot be

+ path names in command line arguments, environment variables
+ and config files (`.git/config` (see linkgit:git-config[1]),
+ linkgit:gitignore[5], linkgit:gitattributes[5] and

++
+Note that Git at the core level treats path names simply as
+sequences of non-NUL bytes, there are no path name encoding
+conversions (except on Mac and Windows). Therefore, using
+non-ASCII path names will mostly work even on platforms and file
+systems that use legacy extended ASCII encodings. However,
+repositories created on such systems will not work properly on
+UTF-8-based systems (e.g. Linux, Mac, Windows) and vice versa.
+Additionally, many Git-based tools simply assume path names to

-lockfile API
-============
-
-The lockfile API serves two purposes:
-
-* Mutual exclusion and atomic file updates. When we want to change a
- file, we create a lockfile `<filename>.lock`, write the new file
- contents into it, and then rename the lockfile to its final
- destination `<filename>`. We create the `<filename>.lock` file with
- `O_CREAT|O_EXCL` so that we can notice and fail if somebody else has
- already locked the file, then atomically rename the lockfile to its
- final destination to commit the changes and unlock the file.
-
-* Automatic cruft removal. If the program exits after we lock a file
- but before the changes have been committed, we want to make sure
- that we remove the lockfile. This is done by remembering the
- lockfiles we have created in a linked list and setting up an
- `atexit(3)` handler and a signal handler that clean up the
- lockfiles. This mechanism ensures that outstanding lockfiles are
- cleaned up if the program exits (including when `die()` is called)
- or if the program dies on a signal.
-
-Please note that lockfiles only block other writers. Readers do not
-block, but they are guaranteed to see either the old contents of the
-file or the new contents of the file (assuming that the filesystem
-implements `rename(2)` atomically).
-
-
-Calling sequence
-----------------
-
-The caller:
-
-* Allocates a `struct lock_file` either as a static variable or on the
- heap, initialized to zeros. Once you use the structure to call the
- `hold_lock_file_*` family of functions, it belongs to the lockfile
- subsystem and its storage must remain valid throughout the life of
- the program (i.e. you cannot use an on-stack variable to hold this
- structure).
-
-* Attempts to create a lockfile by passing that variable and the path
- of the final destination (e.g. `$GIT_DIR/index`) to
- `hold_lock_file_for_update` or `hold_lock_file_for_append`.
-
-* Writes new content for the destination file by either:
-
- * writing to the file descriptor returned by the `hold_lock_file_*`
- functions (also available via `lock->fd`).
-
- * calling `fdopen_lock_file` to get a `FILE` pointer for the open
- file and writing to the file using stdio.
-
-When finished writing, the caller can:
-
-* Close the file descriptor and rename the lockfile to its final
- destination by calling `commit_lock_file` or `commit_lock_file_to`.
-
-* Close the file descriptor and remove the lockfile by calling
- `rollback_lock_file`.
-
-* Close the file descriptor without removing or renaming the lockfile
- by calling `close_lock_file`, and later call `commit_lock_file`,
- `commit_lock_file_to`, `rollback_lock_file`, or `reopen_lock_file`.
-
-Even after the lockfile is committed or rolled back, the `lock_file`
-object must not be freed or altered by the caller. However, it may be
-reused; just pass it to another call of `hold_lock_file_for_update` or
-`hold_lock_file_for_append`.
-
-If the program exits before you have called one of `commit_lock_file`,
-`commit_lock_file_to`, `rollback_lock_file`, or `close_lock_file`, an
-`atexit(3)` handler will close and remove the lockfile, rolling back
-any uncommitted changes.
-
-If you need to close the file descriptor you obtained from a
-`hold_lock_file_*` function yourself, do so by calling
-`close_lock_file`. You should never call `close(2)` or `fclose(3)`
-yourself! Otherwise the `struct lock_file` structure would still think
-that the file descriptor needs to be closed, and a commit or rollback
-would result in duplicate calls to `close(2)`. Worse yet, if you close
-and then later open another file descriptor for a completely different
-purpose, then a commit or rollback might close that unrelated file
-descriptor.
-
-
-Error handling
---------------
-
-The `hold_lock_file_*` functions return a file descriptor on success
-or -1 on failure (unless `LOCK_DIE_ON_ERROR` is used; see below). On
-errors, `errno` describes the reason for failure. Errors can be
-reported by passing `errno` to one of the following helper functions:
-
-unable_to_lock_message::
-
- Append an appropriate error message to a `strbuf`.
-
-unable_to_lock_error::
-
- Emit an appropriate error message using `error()`.
-
-unable_to_lock_die::
-
- Emit an appropriate error message and `die()`.
-
-Similarly, `commit_lock_file`, `commit_lock_file_to`, and
-`close_lock_file` return 0 on success. On failure they set `errno`
-appropriately, do their best to roll back the lockfile, and return -1.
-
-
-Flags
------
-
-The following flags can be passed to `hold_lock_file_for_update` or
-`hold_lock_file_for_append`:
-
-LOCK_NO_DEREF::
-
- Usually symbolic links in the destination path are resolved
- and the lockfile is created by adding ".lock" to the resolved
- path. If `LOCK_NO_DEREF` is set, then the lockfile is created
- by adding ".lock" to the path argument itself. This option is
- used, for example, when locking a symbolic reference, which
- for backwards-compatibility reasons can be a symbolic link
- containing the name of the referred-to-reference.
-
-LOCK_DIE_ON_ERROR::
-
- If a lock is already taken for the file, `die()` with an error
- message. If this option is not specified, trying to lock a
- file that is already locked returns -1 to the caller.
-
-
-The functions
--------------
-
-hold_lock_file_for_update::
-
- Take a pointer to `struct lock_file`, the path of the file to
- be locked (e.g. `$GIT_DIR/index`) and a flags argument (see
- above). Attempt to create a lockfile for the destination and
- return the file descriptor for writing to the file.
-
-hold_lock_file_for_append::
-
- Like `hold_lock_file_for_update`, but before returning copy
- the existing contents of the file (if any) to the lockfile and
- position its write pointer at the end of the file.
-
-fdopen_lock_file::
-
- Associate a stdio stream with the lockfile. Return NULL
- (*without* rolling back the lockfile) on error. The stream is
- closed automatically when `close_lock_file` is called or when
- the file is committed or rolled back.
-
-get_locked_file_path::
-
- Return the path of the file that is locked by the specified
- lock_file object. The caller must free the memory.
-
-commit_lock_file::
-
- Take a pointer to the `struct lock_file` initialized with an
- earlier call to `hold_lock_file_for_update` or
- `hold_lock_file_for_append`, close the file descriptor, and
- rename the lockfile to its final destination. Return 0 upon
- success. On failure, roll back the lock file and return -1,
- with `errno` set to the value from the failing call to
- `close(2)` or `rename(2)`. It is a bug to call
- `commit_lock_file` for a `lock_file` object that is not
- currently locked.
-
-commit_lock_file_to::
-
- Like `commit_lock_file()`, except that it takes an explicit
- `path` argument to which the lockfile should be renamed. The
- `path` must be on the same filesystem as the lock file.
-
-rollback_lock_file::
-
- Take a pointer to the `struct lock_file` initialized with an
- earlier call to `hold_lock_file_for_update` or
- `hold_lock_file_for_append`, close the file descriptor and
- remove the lockfile. It is a NOOP to call
- `rollback_lock_file()` for a `lock_file` object that has
- already been committed or rolled back.
-
-close_lock_file::
-
- Take a pointer to the `struct lock_file` initialized with an
- earlier call to `hold_lock_file_for_update` or
- `hold_lock_file_for_append`. Close the file descriptor (and
- the file pointer if it has been opened using
- `fdopen_lock_file`). Return 0 upon success. On failure to
- `close(2)`, return a negative value and roll back the lock
- file. Usually `commit_lock_file`, `commit_lock_file_to`, or
- `rollback_lock_file` should eventually be called if
- `close_lock_file` succeeds.
-
-reopen_lock_file::
-
- Re-open a lockfile that has been closed (using
- `close_lock_file`) but not yet committed or rolled back. This
- can be used to implement a sequence of operations like the
- following:
-
- * Lock file.
-
- * Write new contents to lockfile, then `close_lock_file` to
- cause the contents to be written to disk.
-
- * Pass the name of the lockfile to another program to allow it
- (and nobody else) to inspect the contents you wrote, while
- still holding the lock yourself.
-
- * `reopen_lock_file` to reopen the lockfile. Make further
- updates to the contents.
-
- * `commit_lock_file` to make the final version permanent.
Introduce an option with integer argument.
The integer is put into `int_var`.
+`OPT_MAGNITUDE(short, long, &unsigned_long_var, description)`::
+ Introduce an option with a size argument. The argument must be a
+ non-negative integer and may include a suffix of 'k', 'm' or 'g' to
+ scale the provided value by 1024, 1024^2 or 1024^3 respectively.
+ The scaled value is put into `unsigned_long_var`.
+
`OPT_DATE(short, long, &int_var, description)`::
Introduce an option with date argument, see `approxidate()`.
The timestamp is put into `int_var`.
Use it to hide deprecated options that are still to be recognized
and ignored silently.
+`OPT_PASSTHRU(short, long, &char_var, arg_str, description, flags)`::
+ Introduce an option that will be reconstructed into a char* string,
+ which must be initialized to NULL. This is useful when you need to
+ pass the command-line option to another command. Any previous value
+ will be overwritten, so this should only be used for options where
+ the last one specified on the command line wins.
+
+`OPT_PASSTHRU_ARGV(short, long, &argv_array_var, arg_str, description, flags)`::
+ Introduce an option where all instances of it on the command-line will
+ be reconstructed into an argv_array. This is useful when you need to
+ pass the command-line option, which can be specified multiple times,
+ to another command.
+
The last element of the array must be `OPT_END()`.

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

- * reference will always be null_sha1 in this case, and the return

- * symbolic reference), REF_BAD_NAME (if the reference name is ill

- * (if the ref is malformed or has a bad name). See refs.h for more detail
- * on each flag.
- *
- * If ref is not a properly-formatted, normalized reference, return
- * NULL. If more than MAXDEPTH recursive symbolic lookups are needed,
- * give up and return NULL.
- *
- * RESOLVE_REF_ALLOW_BAD_NAME allows resolving refs even when their
- * name is invalid according to git-check-ref-format(1). If the name
- * is bad then the value stored in sha1 will be null_sha1 and the two
- * flags REF_ISBROKEN and REF_BAD_NAME will be set.
- *
- * Even with RESOLVE_REF_ALLOW_BAD_NAME, names that escape the refs/
- * directory and do not consist of all caps and underscores cannot be

/*
* 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.
+ * The lockfile API serves two purposes:
+ *
+ * * Mutual exclusion and atomic file updates. When we want to change
+ * a file, we create a lockfile `<filename>.lock`, write the new
+ * file contents into it, and then rename the lockfile to its final
+ * destination `<filename>`. We create the `<filename>.lock` file
+ * with `O_CREAT|O_EXCL` so that we can notice and fail if somebody
+ * else has already locked the file, then atomically rename the
+ * lockfile to its final destination to commit the changes and
+ * unlock the file.
+ *
+ * * Automatic cruft removal. If the program exits after we lock a
+ * file but before the changes have been committed, we want to make
+ * sure that we remove the lockfile. This is done by remembering the
+ * lockfiles we have created in a linked list and setting up an
+ * `atexit(3)` handler and a signal handler that clean up the
+ * lockfiles. This mechanism ensures that outstanding lockfiles are
+ * cleaned up if the program exits (including when `die()` is
+ * called) or if the program is terminated by 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).
+ *
+ * Most of the heavy lifting is done by the tempfile module (see
+ * "tempfile.h").
+ *
+ * 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_for_*()` 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 calling
+ * `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_for_*()` 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 `commit_lock_file()`,
+ * `commit_lock_file_to()`, or `rollback_lock_file()` is called, the
+ * tempfile module will close and remove the lockfile, thereby rolling
+ * back any uncommitted changes.
+ *
+ * If you need to close the file descriptor you obtained from a
+ * `hold_lock_file_for_*()` function yourself, do so by calling
+ * `close_lock_file()`. See "tempfile.h" for more information.
+ *
+ *
+ * Under the covers, a lockfile is just a tempfile with a few helper
+ * functions. In particular, the state diagram and the cleanup
+ * machinery are all implemented in the tempfile module.
+ *
+ *
+ * Error handling
+ * --------------
+ *
+ * The `hold_lock_file_for_*()` functions return a file descriptor on
+ * success or -1 on failure (unless `LOCK_DIE_ON_ERROR` is used; see
+ * "flags" below). On errors, `errno` describes the reason for
+ * failure. Errors can be reported by passing `errno` to
+ * `unable_to_lock_message()` or `unable_to_lock_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.

+The two character language translation codes are defined by ISO_639-1, as
+stated in the gettext(1) full manual, appendix A.1, Usual Language Codes.
+
+
+Contributing to an existing translation
+---------------------------------------
As a contributor for a language XX, you should first check TEAMS file in
this directory to see whether a dedicated repository for your language XX
exists. Fork the dedicated repository and start to work if it exists.
+Sometime, contributors may find that the translations of their Git
+distributions are quite different with the translations of the
+corresponding version from Git official. This is because some Git
+distributions (such as from Ubuntu, etc.) have their own l10n workflow.
+For this case, wrong translations should be reported and fixed through
+their workflows.
+
+
+Creating a new language translation
+-----------------------------------
If you are the first contributor for the language XX, please fork this
repository, prepare and/or update the translated message file po/XX.po
(described later), and ask the l10n coordinator to pull your work.
language, so that the l10n coordinator only needs to interact with one
person per language.

+Translation Process Flow
+------------------------
The overall data-flow looks like this:

+/*
+ * State diagram and cleanup
+ * -------------------------
+ *
+ * If the program exits while a temporary file is active, we want to
+ * make sure that we remove it. This is done by remembering the active
+ * temporary files in a linked list, `tempfile_list`. An `atexit(3)`
+ * handler and a signal handler are registered, to clean up any active
+ * temporary files.
+ *
+ * Because the signal handler can run at any time, `tempfile_list` and
+ * the `tempfile` objects that comprise it must be kept in
+ * self-consistent states at all times.
+ *
+ * The possible states of a `tempfile` 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 `tempfile_list`, and `on_list` is set.
+ *
+ * - Active, file open (after `create_tempfile()` or
+ * `reopen_tempfile()`). In this state:
+ *
+ * - the temporary file exists
+ * - `active` is set
+ * - `filename` holds the filename of the temporary file
+ * - `fd` holds a file descriptor open for writing to it
+ * - `fp` holds a pointer to an open `FILE` object if and only if
+ * `fdopen_tempfile()` has been called on the object
+ * - `owner` holds the PID of the process that created the file
+ *
+ * - Active, file closed (after successful `close_tempfile()`). Same
+ * as the previous state, except that the temporary file is closed,
+ * `fd` is -1, and `fp` is `NULL`.
+ *
+ * - Inactive (after `delete_tempfile()`, `rename_tempfile()`, a
+ * failed attempt to create a temporary file, or a failed
+ * `close_tempfile()`). 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 and `fp` is `NULL`
+ * - the object is left registered in the `tempfile_list`, and
+ * `on_list` is set.
+ *
+ * A temporary file is owned by the process that created it. The
+ * `tempfile` has an `owner` field that records the owner's PID. This
+ * field is used to prevent a forked process from deleting a temporary
+ * file created by its parent.

+/*
+ * Handle temporary files.
+ *
+ * The tempfile API allows temporary files to be created, deleted, and
+ * atomically renamed. Temporary files that are still active when the
+ * program ends are cleaned up automatically. Lockfiles (see
+ * "lockfile.h") are built on top of this API.
+ *
+ *
+ * Calling sequence
+ * ----------------
+ *
+ * The caller:
+ *
+ * * Allocates a `struct tempfile` either as a static variable or on
+ * the heap, initialized to zeros. Once you use the structure to
+ * call `create_tempfile()`, it belongs to the tempfile 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 temporary file by calling
+ * `create_tempfile()`.
+ *
+ * * Writes new content to the file by either:
+ *
+ * * writing to the file descriptor returned by `create_tempfile()`
+ * (also available via `tempfile->fd`).
+ *
+ * * calling `fdopen_tempfile()` 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 remove the temporary file by
+ * calling `delete_tempfile()`.
+ *
+ * * Close the temporary file and rename it atomically to a specified
+ * filename by calling `rename_tempfile()`. This relinquishes
+ * control of the file.
+ *
+ * * Close the file descriptor without removing or renaming the
+ * temporary file by calling `close_tempfile()`, and later call
+ * `delete_tempfile()` or `rename_tempfile()`.
+ *
+ * Even after the temporary file is renamed or deleted, the `tempfile`
+ * object must not be freed or altered by the caller. However, it may
+ * be reused; just pass it to another call of `create_tempfile()`.
+ *
+ * If the program exits before `rename_tempfile()` or
+ * `delete_tempfile()` is called, an `atexit(3)` handler will close
+ * and remove the temporary file.
+ *
+ * If you need to close the file descriptor yourself, do so by calling
+ * `close_tempfile()`. You should never call `close(2)` or `fclose(3)`
+ * yourself, otherwise the `struct tempfile` structure would still
+ * think that the file descriptor needs to be closed, and a later
+ * cleanup 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 the unrelated file descriptor
+ * might get closed.
+ *
+ *
+ * Error handling
+ * --------------
+ *
+ * `create_tempfile()` returns a file descriptor on success or -1 on
+ * failure. On errors, `errno` describes the reason for failure.
+ *
+ * `delete_tempfile()`, `rename_tempfile()`, and `close_tempfile()`
+ * return 0 on success. On failure they set `errno` appropriately, do
+ * their best to delete the temporary file, and return -1.
