When the dirty work tree and index status indicator is enabled,
__git_ps1() checks for changes in the index by running 'git diff-index
--cached --quiet HEAD --' and looking at its exit code. However, that
makes sense only when HEAD points to a valid commit: on an unborn
branch the failure of said command would be caused by the invalid
HEAD, not by changes in the index. Therefore, __git_ps1() first
checks for a valid HEAD by running 'git rev-parse --quiet --verify
HEAD'.
Since the previous patch we implicitly check HEAD's validity by
running 'git rev-parse ... --short HEAD', making the dirty status
indicator's 'git rev-parse' check redundant. It's sufficient to check
for non-emptyness of the variable holding the abbreviated commit
object name, thereby sparing the overhead of fork()+exec()ing a git
process.

When describing a detached HEAD according to the $GIT_PS1_DESCRIBE
environment variable fails, __git_ps1() now runs the '$(git rev-parse
--short HEAD)' command substitution to get the abbreviated detached
HEAD commit object name. This imposes the overhead of fork()ing a
subshell and fork()+exec()ing a git process.
Avoid this overhead by combining this command substitution with the
"main" 'git rev-parse' execution for getting the path to the .git
directory & co. This means that we'll look for the abbreviated commit
object name even when it's not necessary, because we're on a branch or
the detached HEAD can be described. It doesn't matter, however,
because once 'git rev-parse' is up and running to fulfill all those
other queries, the additional overhead of looking for the abbreviated
commit object name is not measurable because it's lost in the noise.
There is a caveat, however, when we are on an unborn branch, because
in that case HEAD doesn't point to a valid commit, hence the query for
the abbreviated commit object name fails. Therefore, '--short HEAD'
must be the last options to 'git rev-parse' in order to get all the
other necessary information for the prompt even on an unborn branch.
Furthermore, in that case, and in that case only, 'git rev-parse'
doesn't output the last line containing the abbreviated commit object
name, obviously, so we have to take care to only parse it if 'git
rev-parse' exited without any error.
Although there are tests already excercising __git_ps1() on unborn
branches, they all do so implicitly. Add a test that checks this
explicitly.

There are a couple of '$(git rev-parse --<opt>)' command substitutions
in __git_ps1() and three of them are executed in the main code path:
- the first to get the path to the .git directory ('--git-dir'),
- the second to check whether we're inside the .git directory
('--is-inside-git-dir'),
- and the last, depending on the results of the second, either
* to check whether it's a bare repo ('--is-bare-repository'), or
* to check whether inside a work tree ('--is-inside-work-tree').
Naturally, this imposes the overhead of fork()ing three subshells and
fork()+exec()ing three git commands.
Combine these four 'git rev-parse' queries into a single one and use
bash parameter expansions to parse the combined output, i.e. to
separate the path to the .git directory from the true/false of
'--is-inside-git-dir', etc. This way we can eliminate two of the
three subshells and git commands.

__git_ps1() runs the '$(git symbolic-ref HEAD)' command substitution
to find out whether we are on a branch and to find out the name of
that branch. This imposes the overhead of fork()ing a subshell and
fork()+exec()ing a git process.
Since HEAD is in most cases a single-line file and the symbolic ref
format is quite simple to recognize and parse, read and parse it using
only bash builtins, thereby sparing all that fork()+exec() overhead.
Don't display the git prompt if reading HEAD fails, because a readable
HEAD is required for a git repository. HEAD can also be a symlink
symbolic ref (due to 'core.preferSymlinkRefs'), so use bash builtins
for reading HEAD only when HEAD is not a symlink.

During an ongoing interactive rebase __git_ps1() finds out the name of
the rebased branch, the total number of patches and the number of the
current patch by executing a '$(cat .git/rebase-merge/<FILE>)' command
substitution for each. That is not quite the most efficient way to
read single line single word files, because it imposes the overhead of
fork()ing a subshell and fork()+exec()ing 'cat' several times.
Use the 'read' bash builtin instead to avoid those overheads.

__git_ps1() finds out the path to the repository by using the
__gitdir() helper function. __gitdir() is basically just a wrapper
around 'git rev-parse --git-dir', extended with support for
recognizing a remote repository given as argument, to use the path
given on the command line, and with a few shortcuts to recognize a git
repository in cwd or at $GIT_DIR quickly without actually running 'git
rev-parse'. However, the former two is only necessary for the
completion script but makes no sense for the bash prompt, while the
latter shortcuts are performance optimizations __git_ps1() can do
without (they just avoid the overhead of fork()+exec()ing a git
process).
Run 'git rev-parse --git-dir' directly in __git_ps1(), because it will
allow this patch series to combine several $(git rev-parse ...)
command substitutions in the main code path, and the overall
performance benefit will far outweigh the loss of those few shortcuts
in __gitdir(). Furthermore, since __gitdir() is not needed anymore
for the prompt, remove it from the prompt script finally eliminating
its duplication between the prompt and completion scripts. Also
remove the comment from the completion script warning about this code
duplication.

The 'git show' completion uses __git_complete_file (aliased to
__git_complete_revlist_file), because accepts <tree-ish>:<path> as
well as <commit-ish>. But the command also accepts range of commits
in A..B notation, so using __git_complete_revlist_file is more
appropriate.
There still remain two users of __git_complete_file, completions for
"archive" and "ls-tree". As these commands do not take range
notation, and "git show" no longer uses __git_complete_file, the
implementation of it can be updated not to complete ranges, but that
is a separate topic.

When a rebase stops (e.g. interrupted by a merge conflict), it could
be useful to know how far a rebase has progressed and how many
commits in total this rebase will apply. Teach the __git_ps1()
command to display the number of commits so far applied and the
total number of commits to be applied, like this:
((3ec0a6a...)|REBASE 2/5)
In the example above the rebase has stopped at the second commit due to
a merge conflict and there are a total number of five commits to be
applied by this rebase.
This information can be already obtained from the following files which are
being generated during the rebase:
GIT_DIR/.git/rebase-merge/msgnum (git-rebase--merge.sh)
GIT_DIR/.git/rebase-merge/end (git-rebase--merge.sh)
GIT_DIR/.git/rebase-apply/next (git-am.sh)
GIT_DIR/.git/rebase-apply/last (git-am.sh)
but "rebase -i" does not leave necessary clues.
Implement this feature by doing these three things:
1) Modify git-rebase--interactive.sh to also create
GIT_DIR/.git/rebase-merge/msgnum
GIT_DIR/.git/rebase-merge/end
files for the number of commits so far applied and the total
number of commits to be applied.

files.

Here are some numbers filtering N amount of words:

original: 0.056s
new: 0.066s
== 100000 ==

new: 0.622s
If the results are not narrowed:
== 1 ==
original: 0.002s
new: 0.000s
== 10 ==
original: 0.002s
new: 0.001s

So, unless 'git checkout <tab>' usually gives you more than 10000
results, you'll get an improvement :)

less than that:

is redirected to /dev/null using a construct that is valid POSIX.1

Even though this file is "git-completion.bash", zsh completion
support dot-sources it (instead of asking bash to grok it like tcsh
completion does), and zsh does not implement this redirection
correctly.
With zsh, trying to complete an inexistant directory gave this:
git add no-such-dir/__git_ls_files_helper💿2: no such file or directory: no-such-dir/
Also these functions use "cd" to first go somewhere else before
running a command, but the location the caller wants them to go that
is given as an argument to them should not be affected by CDPATH
variable the users may have set for their interactive session.
To fix both of these, wrap the body of the function in a subshell,
unset CDPATH at the beginning of the subshell, and redirect the
standard error stream of the subshell to /dev/null.

Commit fea16b47b6 (Fri Jan 11 19:48:43 2013, Manlio Perillo,
git-completion.bash: add support for path completion), introduced a new
__gitcomp_file function that uses the bash builtin "compgen". The
function was redefined for ZSH in the deprecated section of
git-completion.bash, but not in the new git-completion.zsh script.
As a result, users of git-completion.zsh trying to complete "git add
fo<tab>" get an error:
git add fo__gitcomp_file:8: command not found: compgen
This patch adds the redefinition and removes the error.

With "git submodule init" the user is able to tell git he cares about one
or more submodules and wants to have it populated on the next call to "git
submodule update". But currently there is no easy way he could tell git he
does not care about a submodule anymore and wants to get rid of his local
work tree (except he knows a lot about submodule internals and removes the
"submodule.$name.url" setting from .git/config together with the work tree
himself).
Help those users by providing a 'deinit' command. This removes the
whole submodule.<name> section from .git/config (either for the given
submodule(s) or for all those which have been initialized if '.' is used)
together with their work tree. Fail if the current work tree contains
modifications (unless forced), but don't complain when either the work
tree is already removed or no settings are found in .git/config.
Add tests and link the man pages of "git submodule deinit" and "git rm"
to assist the user in deciding whether removing or unregistering the
submodule is the right thing to do for him. Also add the deinit subcommand
to the completion list.

The "complete with known paths only" update to completion scripts
returns directory names without trailing slash to compensate the
addition of '/' done by bash that reads from our completion result.
tcsh completion code that reads from our internal completion result
does not add '/', so let it ask our complletion code to keep the '/'
at the end.
* mk/tcsh-complete-only-known-paths:
completion: handle path completion and colon for tcsh script
The completion script used to let the default completer to suggest
pathnames, which gave too many irrelevant choices (e.g. "git add"
would not want to add an unmodified path). Teach it to use a more
git-aware logic to enumerate only relevant ones.
* mp/complete-paths:
git-completion.bash: add support for path completion
Recent enhancements to git-completion.bash provide intelligent path
completion for git commands. Such completions do not provide the
'/' at the end of directories for recent versions of bash; instead,
bash itself will add the trailing slash to directories to the result
provided by git-completion.bash. However, the completion for tcsh
uses the result of the bash completion script directly, so it either
needs to add the necessary slash itself, or needs to ask the bash
script to keep the trailing slash.
Adding the slash itself is difficult because we have to check the
each path in the output of the bash script to see if it is meant to
be a directory or something else. For example, assuming there is a
directory named 'commit' in the current directory, then, when
completing
git add commit<tab>
we would need to add a slash, but for
git help commit<tab>
we should not.
Figuring out such differences would require adding much intelligence
to the tcsh completion script. Instead, it is simpler to ask the
bash script to keep the trailing slash. This patch does this.
Also, tcsh does not handle the colon as a completion separator so we
remove it from the list of separators.

When you have random build artifacts in your build directory, left
behind by running "make" while on another branch, the "git help -a"
command run by __git_list_all_commands in the completion script that
is being tested does not have a way to know that they are not part
of the subcommands this build will ship. Such extra subcommands may
come from the user's $PATH. They will interfere with the tests that
expect a certain prefix to uniquely expand to a known completion.
Instrument the completion script and give it a way for us to tell
what (subset of) subcommands we are going to ship.
Also add a test to "git --help <prefix><TAB>" expansion. It needs
to show not just commands but some selected documentation pages.

When commit d8b45314 began separating the zsh completion from the bash
completion, it introduced a zsh completion "bridge" section into the bash
completion script for zsh users to use until they migrated to the zsh
script. The zsh '+=()' append-to-array notation prevents bash 3.00.15 on
CentOS 4.x from loading the completion script and breaks test 9902. We can

Some users or projects prefer different algorithms over others, e.g.
patience over myers or similar. However, specifying appropriate
argument every time diff is to be used is impractical. Moreover,
creating an alias doesn't play nicely with other tools based on diff
(git-show for instance). Hence, a configuration variable which is able
to set specific algorithm is needed. For now, these four values are
accepted: 'myers' (which has the same effect as not setting the config
variable at all), 'minimal', 'patience' and 'histogram'.

The git-completion.bash script did not implemented full, git aware,
support to complete paths, for git commands that operate on files within
the current working directory or the index.
As an example:
git add <TAB>
will suggest all files in the current working directory, including
ignored files and files that have not been modified.
Support path completion, for git commands where the non-option arguments
always refer to paths within the current working directory or the index,
as follows:
* the path completion for the "git rm" and "git ls-files"
commands will suggest all cached files.
* the path completion for the "git add" command will suggest all
untracked and modified files. Ignored files are excluded.
* the path completion for the "git clean" command will suggest all
untracked files. Ignored files are excluded.
* the path completion for the "git mv" command will suggest all cached
files when expanding the first argument, and all untracked and cached
files for subsequent arguments. In the latter case, empty directories
are included and ignored files are excluded.
* the path completion for the "git commit" command will suggest all
files that have been modified from the HEAD, if HEAD exists, otherwise
it will suggest all cached files.
For all affected commands, completion will always stop at directory
boundary. Only standard ignored files are excluded, using the
--exclude-standard option of the ls-files command.
When using a recent Bash version, Git path completion will be the same
as builtin file completion, e.g.
git add contrib/
will suggest relative file names.

For bash completion, the option '-o bashdefault' is used to indicate
that when no other choices are available, file completion should be
performed. Since this option is not available in tcsh, no file
completion is ever performed. Therefore, commands like 'git add ',
'git send-email ', etc, require the user to manually type out
the file name. This can be quite annoying.
To improve the user experience we try to simulate file completion
directly in this script (although not perfectly).
The known issues with the file completion simulation are:
- Possible completions are shown with their directory prefix.
- Completions containing shell variables are not handled.
- Completions with ~ as the first character are not handled.

tcsh users sometimes alias the 'git' command to another name. In
this case, the user expects to only have to issue a new 'complete'
command using the alias name.
However, the tcsh script currently uses the command typed by the
user to call the appropriate function in git-completion.bash, either
_git() or _gitk(). When using an alias, this technique no longer
works.
This change specifies the real name of the command (either 'git' or
'gitk') as a parameter to the script handling tcsh completion. This
allows the user to use any alias for the 'git' or 'gitk' commands,
while still getting completion to work.
A check for the presence of ${HOME}/.git-completion.bash is also
added to help the user make use of the script properly.

The user can be presented with invalid completion results
when trying to complete a 'git checkout' command. This can happen
when using a branch name prefix that matches multiple remote branches.
For example, if available branches are:
master
remotes/GitHub/maint
remotes/GitHub/master
remotes/origin/maint
remotes/origin/master
When performing completion on 'git checkout ma' the user will be
given the choices:
maint
master
However, 'git checkout maint' will fail in this case, although
completion previously said 'maint' was valid. Furthermore, when
performing completion on 'git checkout mai', no choices will be
suggested. So, the user is first told that the branch name
'maint' is valid, but when trying to complete 'mai' into 'maint',
that completion is no longer valid.
The completion results should never propose 'maint' as a valid
branch name, since 'git checkout' will refuse it.
The reason for this bug is that the uniq program only
works with sorted input. The man page states
"uniq prints the unique lines in a sorted file".
When __git_refs uses the guess heuristic employed by checkout for
tracking branches it wants to consider remote branches but only if
the branch name is unique. To do that, it calls 'uniq -u'. However
the input given to 'uniq -u' is not sorted.
Therefore, in the above example, when dealing with 'git checkout ma',
"__git_refs '' 1" will find the following list:
master
maint
master
maint
master
which, when passed to 'uniq -u' will remain the same. Therefore
'maint' will be wrongly suggested as a valid option.
When dealing with 'git checkout mai', the list will be:
maint
maint
which happens to be sorted and will be emptied by 'uniq -u',
properly ignoring 'maint'.
A solution for preventing the completion script from suggesting
such invalid branch names is to first call 'sort' and then 'uniq -u'.

Zsh's bash completion emulation is buggy, not properly maintained, and
we have some workarounds in place for different bugs that appeared in
various versions.
Since I'm the only one that has worked on that code lately[1], it might make
snese to use the code I wrote specifically for git.
The advantages are:
1) Less workarounds
* No need to hack __get_comp_words_by_ref
* No need to hack IFS or words
2) Improved features
* 'git show master' now properly adds a space at the end (IFS bug)
* 'git checkout --conflict=' now properly returns the sub-items
(missing feature)
3) Consolidated code
* It's all now in a single chunk, and it's basically the same as
git-completion.zsh
Since there's some interest in moving the zsh-specific code out of this
script, lets go ahead and warn the users that they should be using
git-completion.zsh.

The current tcsh-completion support for Git, as can be found on the
Internet, takes the approach of defining the possible completions
explicitly. This has the obvious draw-back to require constant
updating as the Git code base evolves.
The approach taken by this commit is to to re-use the advanced bash
completion script and use its result for tcsh completion. This is
achieved by sourcing the bash script and outputting the completion
result for tcsh consumption.
Three solutions were looked at to implement this approach with (C)
being retained:
A) Modifications:
git-completion.bash and new git-completion.tcsh
Modify the existing git-completion.bash script to support
being sourced using bash (as now), but also executed using bash.
When being executed, the script will output the result of the
computed completion to be re-used elsewhere (e.g., in tcsh).
The modification to git-completion.bash is made not to be
tcsh-specific, but to allow future users to also re-use its
output. Therefore, to be general, git-completion.bash accepts a
second optional parameter, which is not used by tcsh, but could
prove useful for other users.
Pros:
1- allows the git-completion.bash script to easily be re-used
2- tcsh support is mostly isolated in git-completion.tcsh
Cons (for tcsh users only):
1- requires the user to copy both git-completion.tcsh and
git-completion.bash to ${HOME}
2- requires bash script to have a fixed name and location:
${HOME}/.git-completion.bash
B) Modifications:
git-completion.bash
Modify the existing git-completion.bash script to support
being sourced using bash (as now), but also executed using bash,
and sourced using tcsh.
Pros:
1- only requires the user to deal with a single file
2- maintenance more obvious for tcsh since it is entirely part
of the same git-completion.bash script.
Cons:
1- tcsh support could affect bash support as they share the
same script
2- small tcsh section must use syntax suitable for both tcsh
and bash and must be at the beginning of the script
3- requires script to have a fixed name and location:
${HOME}/.git-completion.sh (for tcsh users only)
C) Modifications:
New git-completion.tcsh
Provide a short tcsh script that generates another script
which extends git-completion.bash. This new script can be
used by tcsh to perform completion.
Pros:
1- tcsh support is entirely isolated in git-completion.tcsh
2- new tcsh script can be as complex as needed
Cons (for tcsh users only):
1- requires the user to copy both git-completion.tcsh and
git-completion.bash to ${HOME}
2- requires bash script to have a fixed name and location:
${HOME}/.git-completion.bash
3- sourcing the new script will generate a third script
Approach (C) was selected avoid any modification to git-completion.bash.

subshell when the current directory is at the top of the work tree,
i.e. when it contains a '.git' subdirectory.
If the 'GIT_DIR' environment variable is set then it specifies the
path to the git repository, and the autodetection of the '.git'
directory is not necessary. However, $GIT_DIR is only taken into
acocunt by 'git rev-parse --git-dir', and the check for the '.git'
subdirectory is performed first, so it wins over the path given in
$GIT_DIR.
There are several completion (helper) functions that depend on
__gitdir(), and when the above case triggers the completion script
will do weird things, like offering refs, aliases, or stashes from a
different repository, or displaying wrong or broken prompt, etc.
So check first whether $GIT_DIR is set, and only proceed with checking
the '.git' directory in the current directory if it isn't. 'git
rev-parse' would also check whether the path in $GIT_DIR is a proper
'.git' directory, i.e. 'HEAD', 'refs/', and 'objects/' are present and
accessible, but we don't have to be that thorough for the bash prompt.
And we've lived with an equally permissive check for '.git' in the
current working directory for years anyway.

Commit 7f02f3d7 (completion: rename internal helpers _git and _gitk,
2012-05-19) renamed said functions to _main_git() and _main_gitk(),
respectively. By convention the name of our git-completion-specific
functions start with '_git' or '__git' prefix, so rename those
functions once again to put them back into our "namespace". Use the
two underscore prefix, because _git_main() could be mistaken for the
completion function of the (not yet existing) 'git main' command.

The __gitdir function is duplicated between completion and prompt
scripts, and these definitions should not diverge; otherwise one of
them can be subtly broken depending on the order the user's shell
dot-sources them.
Leave a note to people who may want to touch one copy to make sure
they update the other one in sync. Hopefully this line would also
appear in the context of the patch to allow reviewers to notice a
patch that attempts to update only one of them.

bash-completion 1.90 shipped with support to load completions
dynamically[1], which means the git completion script wouldn't be loaded
until the user types 'git <tab>'--this creates a problem to people using
__git_ps1(); that function won't be available when the shell is first
created.
For now distributions have workarounded this issue by moving the git
completion to the "compatdir"[2]; this of course is not ideal.
The solution, proposed by Kerrick Staley[3], is to split the git script
in two; the part that deals with __git_ps1() in one (i.e.
git-prompt.sh), and everything else in another (i.e.
git-completion.bash).
Another benefit of this is that zsh user that are not interested in the
bash completion can use it for their prompts, which has been tried
before[4].
The only slight issue is that __gitdir() would be duplicated, but this
is probably not a big deal.
So let's go ahead and move __git_ps1() to a new file.
While at this, I took the liberty to reformat the help text in the new
file.

No reason to have it executable. Every way this script is intended to be
used includes the 'source' command.

Some people might be relying on _git and _gitk to define custom aliases,
unfortunately, commit 6b179ad (completion: add new __git_complete
helper) broke that support.
"bash: [: 1: unary operator expected"
This can be easily fixed by using __git_complete, but it's not meant to
be public.
Although _git and _gitk are probably not meant to be public, it's easy
to keep having support for them by having a wrapper to the proper
new function that is fully functional.
