7fe9031920 git-prompt.sh: refactor colored prompt code
__git_ps1_colorize_gitstring() sets color codes and
builds the prompt gitstring. It has duplicated code
to handle color codes for bash and zsh shells.
__git_ps1() also has duplicated logic to build the
prompt gitstring.

Remove duplication of logic to build gitstring in
__git_ps1_colorize_gitstring() and __git_ps1().

Leave in __git_ps1_colorize_gitstring() only logic
to set color codes.

a694258457 bash prompt: mention that PROMPT_COMMAND mode is faster
__git_ps1() is usually added to the prompt inside a command
substitution, imposing the overhead of fork()ing a subshell.  Using
__git_ps1() for $PROMPT_COMMAND is slightly faster, because it avoids
that command substitution.

Mention this in the comments about setting up the git prompt.

The whole series speeds up the bash prompt on Windows/MSysGit
considerably.  Here are some timing results in three scenarios, each
repeated 10 times:

At the top of the work tree, before:

    $ time for i in {0..9} ; do prompt="$(__git_ps1)" ; done

    real    0m1.716s
    user    0m0.301s
    sys     0m0.772s

  After:

    real    0m0.687s
    user    0m0.075s
    sys     0m0.396s

  After, from $PROMPT_COMMAND:

    $ time for i in {0..9} ; do __git_ps1 '\h:\w' '$ ' ; done

    real    0m0.546s
    user    0m0.075s
    sys     0m0.181s

At the top of the work tree, detached head, before:

    real    0m2.574s
    user    0m0.376s
    sys     0m1.207s

  After:

    real    0m1.139s
    user    0m0.151s
    sys     0m0.500s

  After, from $PROMPT_COMMAND:

    real    0m1.030s
    user    0m0.245s
    sys     0m0.336s

In a subdirectory, during rebase, stash status indicator enabled,
before:

    real    0m3.557s
    user    0m0.495s
    sys     0m1.767s

  After:

    real    0m0.717s
    user    0m0.120s
    sys     0m0.300s

  After, from $PROMPT_COMMAND:

    real    0m0.577s
    user    0m0.047s
    sys     0m0.258s

On Linux the speedup ratio is comparable to Windows, but overall it
was about an order of magnitude faster to begin with.  The last case
from above, repeated 100 times, before:

    $ time for i in {0..99} ; do prompt="$(__git_ps1)" ; done

    real    0m2.806s
    user    0m0.180s
    sys     0m0.264s

  After:

    real    0m0.857s
    user    0m0.020s
    sys     0m0.028s

69a8141a5d bash prompt: avoid command substitution when finalizing gitstring
Before setting $PS1, __git_ps1() uses a command substitution to
redirect the output from a printf into a variable.  Spare the overhead
of fork()ing a subshell by using 'printf -v <var>' to directly assign
the output to that variable.

zsh's printf doesn't support the '-v <var>' option, so stick with the
command substitution when under zsh.

14d7649748 bash prompt: avoid command substitution when checking for untracked files
When enabled, the bash prompt can indicate the presence of untracked
files with a '%' sign.  __git_ps1() checks for untracked files by running the
'$(git ls-files --others --exclude-standard)' command substitution,
and displays the indicator when there is no output.

Avoid this command substitution by additionally passing
'--error-unmatch *', and checking the command's return value.

dd0b72cbd9 bash prompt: use bash builtins to check stash state
When the environment variable $GIT_PS1_SHOWSTASHSTATE is set
__git_ps1() checks the presence of stashes by running 'git rev-parse
--verify refs/stash'.  This command not only checks that the
'refs/stash' ref exists but also, well, verifies that it's a valid
ref.

However, we don't need to be that thorough for the bash prompt.  We
can omit that verification and only check whether 'refs/stash' exists
or not.  Since 'git pack-refs' never packs 'refs/stash', it's a matter
of checking the existence of a ref file.  Perform this check using
only bash builtins to spare the overhead of fork()+exec()ing a git
process.

Also run 'git pack-refs --all' in the corresponding test to document
that the prompt script depends on 'git pack-refs' not packing
'refs/stash' and to catch possible breakages should this behavior ever
change.

0f37c12581 bash prompt: use bash builtins to check for unborn branch for dirty state
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.

e3e0b9378b bash prompt: combine 'git rev-parse' for detached head
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.

efaa0c1532 bash prompt: combine 'git rev-parse' executions in the main code path
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.

3a43c4b5bd bash prompt: use bash builtins to find out current branch
__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.

b91b935f04 bash prompt: use bash builtins to find out rebase state
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.

511ad15904 bash prompt: run 'git rev-parse --git-dir' directly instead of __gitdir()
__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.

e8f21caf94 bash prompt: print unique detached HEAD abbreviated object name
When describing a detached HEAD according to the $GIT_PS1_DESCRIBE
environment variable fails, __git_ps1() runs 'cut -c1-7 .git/HEAD' to
show the 7 hexdigits abbreviated commit object name in the prompt.
Obviously, this neither respects core.abbrev nor produces a unique
object name.

Fix this by using 'git rev-parse --short HEAD' instead and adjust the
corresponding test to use non-standard number of hexdigits.

5269f7f8c6 completion: show can take both revlist and paths
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.

To reproduce the problem, the __git_ps1_show_upstream function can be

Zsh also doesn't support initializing an array with `local var=(...)`.
This triggers the following error:

1ca6d4bc42 complete: zsh: trivial simplification
There should be no functional changes.

The only reason I wrapped this code around a sub-function is because zsh
did the same in it's bashcompinit script in order to declare the special
variable 'words' as hidden, but only in this context.

There's no need for that any more since we access __git_main directly,
so 'words' is not modified, so there's no need for the sub-function.

In zsh mode the array indexes are different though.

At the end of the day what we really need is to find out the files that
have been staged, or modified, because those files are the ones that
make sense to pass as arguments to 'git commit'.

We need diff-index to find those out, since 'git ls-files' doesn't do
that.

But we don't need wrappers and wrappers basically identical to the ones
used for 'git ls-files', when we can pretend it receives a --committable
option that would return what we need.

That way, we can remove a bunch of code without any functional changes.

b71dc3e1a0 bash-prompt.sh: show where rebase is at when stopped
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.

  2) Modify git-prompt.sh to read and display info from the above
     files.

  3) Update test t9903-bash-prompt.sh to reflect changes introduced
     by this patch.

We signal presense of untracked files by adding a per-cent sign '%'
to the prompt.  But because '%' is used as an escape character to
introduce prompt customization in zsh (just like bash prompt uses
'\' to escape '\u', '\h', etc.), we need to say '%%' to get a
literal per-cent.

b4cfbc969c completion: inline __gitcomp_1 to its sole callsite
There is no point in calling a separate function that is only used
in one place. Especially considering that there's no need to call
compgen, and we traverse the words ourselves both in __gitcompadd,
and __gitcomp_1.

Let's squash the functions together, and traverse only once.

This improves performance. For N number of words:

  == 1 ==
  original: 0.002s
  new: 0.000s
  == 10 ==
  original: 0.005s
  new: 0.001s

7d13e0a3af completion: get rid of compgen
The functionality we use from compgen is not much, we can do the same
manually, with drastic improvements in speed, especially when dealing
with only a few words.

This patch also has the sideffect that brekage reported by Jeroen Meijer
and SZEDER Gábor gets fixed because we no longer expand the resulting
words.

Here are some numbers filtering N amount of words:

  == 1 ==
  original: 0.002s
  new: 0.000s
  == 10 ==
  original: 0.002s
  new: 0.000s
  == 100 ==
  original: 0.003s
  new: 0.002s
  == 1000 ==
  original: 0.012s
  new: 0.011s
  == 10000 ==
  original: 0.056s
  new: 0.066s
  == 100000 ==
  original: 2.669s
  new: 0.622s

If the results are not narrowed:

  == 1 ==
  original: 0.002s
  new: 0.000s
  == 10 ==
  original: 0.002s
  new: 0.001s
  == 100 ==
  original: 0.004s
  new: 0.004s
  == 1000 ==
  original: 0.020s
  new: 0.015s
  == 10000 ==
  original: 0.101s
  new: 0.355s
  == 100000 ==
  original: 2.850s
  new: 31.941s

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

Other possible solutions perform better after 1000 words, but worst if
less than that:

  COMPREPLY=($(awk -v cur="$3" -v pre="$2" -v suf="$4"
	'$0 ~ cur { print pre$0suf }' <<< "$1" ))

  COMPREPLY=($(printf -- "$2%s$4\n" $1 | grep "^$2$3"))

35ba83ccf6 git-completion.bash: zsh does not implement function redirection correctly
A recent change added functions whose entire standard error stream
is redirected to /dev/null using a construct that is valid POSIX.1
but is not widely used:

	funcname () {
		cd "$1" && run some command "$2"
	} 2>/dev/null

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,

__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

cf41982806 submodule: add 'deinit' command
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.

This needs to be done in two places: __git_config_get_set_variables to
allow clever completion of "git config --local --get foo<tab>", and
_git_config to allow "git config --loc<tab>" to complete to --local.

While we're there, change the order of options in the code to match

c6929ff239 completion: handle path completion and colon for tcsh script
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.

5047822347 t9902: protect test from stray build artifacts
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.

Based on an idea by Jeff King.

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'.

fea16b47b6 git-completion.bash: add support for path completion
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.

the confusing one should be an alternate for advanced users.  Swap

75ed918bda Add file completion to tcsh git completion.
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.

ce45ea6a13 Support for git aliasing for tcsh completion
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.

4db42b3823 Completion must sort before using uniq
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'.

d8b453149c completion: start moving to the new zsh completion
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.

9673b8c392 tcsh-completion re-using git-completion.bash
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.

585b96bd4c completion: remove 'help' duplicate from porcelain commands
The list of all git commands is computed from the output of 'git help
-a', which already includes 'help', so there is no need to explicitly
add it once more when computing the list of porcelain commands.

Note that 'help' wasn't actually offered twice because of this,
because Bash filters duplicates from possible completion words.

That patch does fix expansion of weird variables in some

expansion of refs by "git checkout".

While we're sorting out the correct solution, we are much
better with the original bug (people with metacharacters in

the current bug (ref completion does not work at all).

25ae7cfd19 completion: fix shell expansion of items
As reported by Jeroen Meijer[1]; the current code doesn't deal properly
with items (tags, branches, etc.) that have ${} in them because they get
expaned by bash while using compgen.

A simple solution is to quote the items so they get expanded properly
(\$\{\}).

In order to achieve that I took bash-completion's quote() function,
which is rather simple, and renamed it to __git_quote() as per Jeff
King's suggestion.

Solves the original problem for me.

b7be4366ea completion: respect $GIT_DIR
The __gitdir() helper function finds out the path of the git
repository by running 'git rev-parse --git-dir'.  However, it has a
shortcut first to avoid the overhead of running a git command in a
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.

af31a456b4 completion: split __git_ps1 into a separate script
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.

unfortunately, commit 6b179ad (completion: add new __git_complete

This can be easily fixed by using __git_complete, but it's not meant to

to keep having support for them by having a wrapper to the proper

911d5da6f2 completion: fix completion after 'git --option <TAB>'
The bash completion doesn't work when certain options to git itself are
specified, e.g. 'git --no-pager <TAB>' errors out with

    error: invalid key: alias.--no-pager

The main _git() completion function finds out the git command name by
looping through all the words on the command line and searching for
the first word that is not a known option for the git command.

Unfortunately the list of known git options was not updated in a long
time, and newer options are not skipped but mistaken for a git command.
Such a misrecognized "command" is then passed to __git_aliased_command(),
which in turn passes it to a 'git config' query, hence the error.

Currently the following options are misrecognized for a git command:

  -c --no-pager --exec-path --html-path --man-path --info-path
  --no-replace-objects --work-tree= --namespace=

To fix this we could just update the list of options to be skipped,
but the same issue will likely arise, if the git command learns a new
option in the future.  Therefore, to make it more future proof against
new options, this patch changes that loop to skip all option-looking
words, i.e. words starting with a dash.

We also have to handle the '-c' option specially, because it takes a
configutation parameter in a separate word, which must be skipped,
too.

3ffcd08688 completion: avoid trailing space for --exec-path
"--exec-path" looks to the completion script like an unambiguous
successful completion, but it is wrong to emit a SP after it as if
declaring that we are done with completion; the user could be trying
to do

	git --exec-path; # print name of helper directory

or

	git --exec-path=/path/to/alternative/helper/dir <subcommand>

so the most helpful thing to do is to leave out the trailing space and
leave it to the operator to type an equal sign or carriage return
according to the situation.

df44483a5d diff --stat: add config option to limit graph width
Config option diff.statGraphWidth=<width> is equivalent to
--stat-graph-width=<width>, except that the config option is ignored
by format-patch.

For the graph-width limiting to be usable, it should happen
'automatically' once configured, hence the config option.
Nevertheless, graph width limiting only makes sense when used on a
wide terminal, so it should not influence the output of format-patch,
which adheres to the 80-column standard.

If the argument for `__git_ps1` begins with a dash, `printf` tries to
interpret it as an option which results in an error message.
The problem is solved by adding '--' before the argument to tell
`printf` to not interpret the following argument as an option.
Adding '--' directly to the argument does not help because the argument
is enclosed by double quotes.

cf0ff02a38 completion: work around zsh option propagation bug
When listing commands in zsh (git <TAB><TAB>), all of them will show up,
instead of only porcelain ones.

The root cause of this is because zsh versions from 4.3.0 to present
(4.3.15) do not correctly propagate the SH_WORD_SPLIT option into the
subshell in ${foo:=$(bar)} expressions. Because of this bug, the list of
all commands was treated as a single word in __git_list_porcelain_commands
and did not match any of the patterns that would usually cause plumbing to
be excluded.

With problematic versions of zsh, after running

	emulate sh
	fn () {
		var='one two'
		for v in $var; do echo $v; done
	}
	x=$(fn)
	: ${y=$(fn)}

printing "$x" results in two lines as expected, but printing "$y" results
in a single line because $var is expanded as a single word when evaluating
fn to compute y.

So avoid the construct, and use an explicit 'test -n "$foo" || foo=$(bar)'
instead.

[jn: clarified commit message, indentation style fix]

f15026b514 git-completion: workaround zsh COMPREPLY bug
zsh adds a backslash (foo\ ) for each item in the COMPREPLY array if IFS
doesn't contain spaces. This issue has been reported[1], but there is no
solution yet.

This wasn't a problem due to another bug[2], which was fixed in zsh
version 4.3.12. After this change, 'git checkout ma<tab>' would resolve
to 'git checkout master\ '.

Aditionally, the introduction of __gitcomp_nl in commit a31e626
(completion: optimize refs completion) in git also made the problem
apparent, as Matthieu Moy reported.

The simplest and most generic solution is to hide all the changes we do
to IFS, so that "foo \nbar " is recognized by zsh as "foo bar". This
works on versions of git before and after the introduction of
__gitcomp_nl (a31e626), and versions of zsh before and after 4.3.12.

Once zsh is fixed, we should conditionally disable this workaround to
have the same benefits as bash users.

6f2dd720b6 bash completion: use read -r everywhere
We use the 'read' command without -r, so that it treats '\' as an
escape character, in several places.  This breaks the loop reading
refnames from git-for-each-ref in __git_refs() if there are refnames
such as "foo'bar", in which case for-each-ref helpfully quotes them as

  $ git update-ref "refs/remotes/test/foo'bar" HEAD
  $ git for-each-ref --shell --format="ref=%(refname:short)" "refs/remotes"
  ref='test/foo'\''bar'

Interpolating the \' here will read "ref='test/foo'''bar'" instead, and
eval then chokes on the unbalanced quotes.

However, since none of the read loops _want_ to have backslashes
interpolated, it's much safer to use read -r everywhere.

6486ca6d77 completion: remove broken dead code from __git_heads() and __git_tags()
__git_heads() was introduced in 5de40f5 (Teach bash about
git-repo-config., 2006-11-27), and __git_tags() in 88e21dc (Teach bash
about completing arguments for git-tag, 2007-08-31).  As their name
suggests, __git_heads() is supposed to list only branches, and
__git_tags() only tags.

Since their introduction both of these functions consist of two
distinct parts.  The first part gets branches or tags, respectively,
from a local repositoty using 'git for-each-ref'.  The second part
queries a remote repository given as argument using 'git ls-remote'.

These remote-querying parts are broken in both functions since their
introduction, because they list both branches and tags from the remote
repository.  (The 'git ls-remote' query is not limited to list only
heads or tags, respectively, and the for loop filtering the query
results prints everything except dereferenced tags.)  This breakage
could be easily fixed by passing the '--heads' or '--tags' options or
appropriate refs patterns to the 'git ls-remote' invocations.

However, that no one noticed this breakage yet is probably not a
coincidence: neither of these two functions were used to query a
remote repository, the remote-querying parts were dead code already
upon thier introduction and remained dead ever since.

Since those parts of code are broken, are and were never used, stop
the bit-rotting and remove them.

d51a8ecd5f completion: fast initial completion for config 'remote.*.fetch' value
Refspecs for branches in a remote repository start with 'refs/heads/',
so completing those refspecs with 'git config remote.origin.fetch
<TAB>' always offers 'refs/heads/' first, because that's the unique
part of the possible refspecs.  But it does so only after querying the
remote with 'git ls-remote', which can take a while when the request
goes through some slower network to a remote server.

Don't waste the user's time and offer 'refs/heads/' right away for
'git config remote.origin.fetch <TAB>'.

The reason for putting 'refs/heads/' directly into COMPREPLY instead
of using __gitcomp() is to avoid __gitcomp() adding a trailing space.
