+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.
+
+Also contains typofixes, documentation updates and trivial code

+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".
+
+
+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.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.5

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.<ref>.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>.
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
- are under the hierarchies listed on the value of this
- variable is excluded, and is hidden when responding to `git
- push`, and an attempt to update or delete a hidden ref by
- `git push` is rejected.
+ This variable is the same as `transfer.hideRefs`, but applies
+ only to `receive-pack` (and so affects pushes, but not fetches).
+ An attempt to update or delete a hidden ref by `git push` is
+ rejected.
receive.updateServerInfo::
If set to true, git-receive-pack will run git-update-server-info
Defaults to false.
transfer.hideRefs::
- This variable can be used to set both `receive.hideRefs`
- and `uploadpack.hideRefs` at the same time to the same
- values. See entries for these other variables.
+ String(s) `receive-pack` and `upload-pack` use to decide which
+ refs to omit from their initial advertisements. Use more than
+ one definition to specify multiple prefix strings. A ref that is
+ under the hierarchies listed in the value of this variable is
+ excluded, and is hidden when responding to `git push` or `git
+ fetch`. See `receive.hideRefs` and `uploadpack.hideRefs` for
+ program-specific versions of this config.
++
+You may also include a `!` in front of the ref name to negate the entry,
+explicitly exposing it, even if an earlier entry marked it as hidden.
+If you have multiple hideRefs values, later entries override earlier ones
+(and entries in more-specific config files override less-specific ones).
transfer.unpackLimit::
When `fetch.unpackLimit` or `receive.unpackLimit` are
`false`.
uploadpack.hideRefs::
- String(s) `upload-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
- are under the hierarchies listed on the value of this
- variable is excluded, and is hidden from `git ls-remote`,
- `git fetch`, etc. An attempt to fetch a hidden ref by `git
- fetch` will fail. See also `uploadpack.allowTipSHA1InWant`.
+ This variable is the same as `transfer.hideRefs`, but applies
+ only to `upload-pack` (and so affects only fetches, not pushes).
+ An attempt to fetch a hidden ref by `git fetch` will fail. See

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.
+
Bisect visualize
~~~~~~~~~~~~~~~~
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

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

--normalize::

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

-
- - *(h)gct* (http://www.cyd.liu.se/users/~freku045/gct/)
-
- Commit Tool or (h)gct is a GUI enabled commit tool for Git and
- Mercurial (hg). It allows the user to view diffs, select which files
- to committed (or ignored / reverted) write commit messages and
- perform the commit itself.
-
- - *git.el* (contrib/)
-
- This is an Emacs interface for Git. The user interface is modelled on

-At the core level, Git is character encoding agnostic.
-
- - The pathnames recorded in the index and in the tree objects
- are treated as uninterpreted sequences of non-NUL bytes.
- What readdir(2) returns are what are recorded and compared
- with the data Git keeps track of, which in turn are expected
- to be what lstat(2) and creat(2) accepts. There is no such
- thing as pathname encoding translation.
+Git is to some extent character encoding agnostic.
- The contents of the blob objects are uninterpreted sequences
of bytes. There is no encoding translation at the core
level.
- - The commit log messages are uninterpreted sequences of non-NUL
- bytes.
+ - Path names are encoded in UTF-8 normalization form C. This
+ applies to tree objects, the index file, ref names, as well as
+ 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
+ linkgit:gitmodules[5]).
++
+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
+be UTF-8 and will fail to display other encodings correctly.
+
+ - Commit log messages are typically encoded in UTF-8, but other
+ extended ASCII encodings are also supported. This includes
+ ISO-8859-x, CP125x and many others, but _not_ UTF-16/32,
+ EBCDIC and CJK multi-byte encodings (GBK, Shift-JIS, Big5,
+ EUC-x, CP9xx etc.).
Although we encourage that the commit log messages are encoded
in UTF-8, both the core and Git Porcelain are designed not to
+
`--date=raw` shows the date in the internal raw Git format `%s %z` format.
+
+`--date=format:...` feeds the format `...` to your system `strftime`.
+Use `--date=format:%c` to show the date in your system locale's
+preferred format. See the `strftime` manual for a complete list of
+format placeholders.
++
`--date=default` shows timestamps in the original time zone
(either committer's or author's).
Format a string and push it onto the end of the array. This is a
convenience wrapper combining `strbuf_addf` and `argv_array_push`.
+`argv_array_pushv`::
+ Push a null-terminated array of strings onto the end of the array.
+
`argv_array_pop`::
Remove the final element from the array. If there are no
elements in the array, do nothing.
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()`.
- The directory name terminated by NUL.
- - A number of untrached file/dir names terminated by NUL.

- * return value, if not NULL, is a pointer into either a static buffer
- * or the input ref.
- *
- * If the reference cannot be resolved to an object, the behavior
- * depends on the RESOLVE_REF_READING flag:
- *
- * - If RESOLVE_REF_READING is set, return NULL.
- *
- * - If RESOLVE_REF_READING is not set, clear sha1 and return the name of
- * the last reference name in the chain, which will either be a non-symbolic
- * reference or an undefined reference. If this is a prelude to
- * "writing" to the ref, the return value is the name of the ref
- * that will actually be created or changed.
- *
- * If the RESOLVE_REF_NO_RECURSE flag is passed, only resolves one
- * level of symbolic reference. The value stored in sha1 for a symbolic
- * reference will always be null_sha1 in this case, and the return
- * value is the reference that the symref refers to directly.
- *
- * If flags is non-NULL, set the value that it points to the
- * combination of REF_ISPACKED (if the reference was found among the
- * packed references), REF_ISSYMREF (if the initial reference was a
- * symbolic reference), REF_BAD_NAME (if the reference name is ill
- * formed --- see RESOLVE_REF_ALLOW_BAD_NAME below), and REF_ISBROKEN
- * (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
- * resolved. The function returns NULL for such ref names.
- * Caps and underscores refers to the special refs, such as HEAD,
