  git-completion.bash: zsh does not implement function redirection correctly

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.

926eb7ba4c git-completion.zsh: define __gitcomp_file compatibility function
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.

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.

50c5885e05 git-completion.bash: replace zsh notation that breaks bash 3.X
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
easily work around this by using standard Bash array notation.

Since command line options have higher priority than config file

07ab4dec80 config: Introduce diff.algorithm variable
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'.

5471fb1c4c Merge branch 'so/prompt-command'
Updates __git_ps1 so that it can be used as $PROMPT_COMMAND,
instead of being used for command substitution in $PS1, to embed
color escape sequences in its output.

* so/prompt-command:
  coloured git-prompt: paint detached HEAD marker in red
  Fix up colored git-prompt
  show color hints based on state of the git tree
  Allow __git_ps1 to be used in PROMPT_COMMAND

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.

c9407860f4 completion: add new zsh completion
It seems there's always issues with zsh's bash completion emulation.
I've tried to fix as many as I could[1], and most of the fixes are already
in the latest version of zsh, but still, there are issues.

There is no point going through all that pain; the emulation is easy to
achieve, and this patch works better than zsh's bash completion
emulation.

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.
