Pete Wyckoff a93d33ee7b git-p4: set useClientSpec variable on initial clone
If --use-client-spec was given, set the matching configuration
variable.  This is necessary to ensure that future submits
work properly.

The alternatives of requiring the user to set it, or providing
a command-line option on every submit, are error prone.

Christian Hammerl f24a595f72 completion: Allow dash as the first character for __git_ps1
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.

These shell functions are written in an unnecessarily verbose way;

Felipe Contreras 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]

Felipe Contreras 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.

Thomas Rast 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.

Jeff King 34961d30da contrib: add credential helper for OS X Keychain
With this installed in your $PATH, you can store
git-over-http passwords in your keychain by doing:

  git config credential.helper osxkeychain

The code is based in large part on the work of Jay Soffian,
who wrote the helper originally for the initial, unpublished
version of the credential helper protocol.

This version will pass t0303 if you do:

  GIT_TEST_CREDENTIAL_HELPER=osxkeychain \
  GIT_TEST_CREDENTIAL_HELPER_SETUP="export HOME=$HOME" \
  ./t0303-credential-external.sh

The "HOME" setup is unfortunately necessary. The test
scripts set HOME to the trash directory, but this causes the
keychain API to complain.

Gary Gibbons bf1d68ff4c git-p4: use absolute directory for PWD env var
P4 only looks at the environment variable $PWD to figure out
where it is, so chdir() has code to set that every time.  But
when the clone --destination is not an absolute path, PWD will
not be absolute and P4 won't be able to find any files expected
to be in the current directory.  Fix this by expanding PWD to
an absolute path.

One place this crops up is when using a P4CONFIG environment
variable to specify P4 parameters, such as P4USER or P4PORT.
Setting P4CONFIG=.p4config works for p4 invocations from the
current directory.  But if the value of PWD is not absolute, it
fails.

SZEDER Gábor 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.

SZEDER Gábor 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.

SZEDER Gábor d79bcf2cf2 completion: query only refs/heads/ in __git_refs_remotes()
__git_refs_remotes() is used to provide completion for refspecs to set
'remote.*.fetch' config variables for branches on the given remote.
So it's really only interested in refs under 'refs/heads/', but it
queries the remote for all its refs and then filters out all refs
outside of 'refs/heads/'.

Let 'git ls-remote' do the filtering.

Also remove the unused $cmd variable from __git_refs_remotes().

SZEDER Gábor fb772cca2b completion: support full refs from remote repositories
When the __git_refs() completion helper function lists refs from a
local repository, it usually lists the refs' short name, except when
it needs to provide completion for words starting with refs, because
in that case it lists full ref names, see 608efb87 (bash: complete
full refs, 2008-11-28).

Add the same functionality to the code path dealing with remote
repositories, too.

SZEDER Gábor d8c0453e1a completion: improve ls-remote output filtering in __git_refs()
The remote-handling part of __git_refs() has a nice for loop and state
machine case statement to iterate over all words from the output of
'git ls-remote' to identify object names and ref names.  Since each
line in the output of 'git ls-remote' consists of an object name and a
ref name, we can do more effective filtering by using a while-read
loop and letting bash's word splitting take care of object names.
This way the code is easier to understand and the loop will need only
half the number of iterations than before.

SZEDER Gábor abf05987de completion: make refs completion consistent for local and remote repos
For a local repository the __git_refs() completion helper function
lists refs under 'refs/(tags|heads|remotes)/', plus some special refs
like HEAD and ORIG_HEAD.  For a remote repository, however, it lists
all refs.

Fix this inconsistency by specifying refs filter patterns for 'git
ls-remote' to only list refs under 'refs/(tags|heads|remotes)/'.

For now this makes it impossible to complete refs outside of
'refs/(tags|heads|remotes)/' in a remote repository, but a followup
patch will resurrect that.

SZEDER Gábor a31e62629a completion: optimize refs completion
After a unique command or option is completed, in most cases it is a
good thing to add a trailing a space, but sometimes it doesn't make
sense, e.g. when the completed word is an option taking an argument
('--option=') or a configuration section ('core.').  Therefore the
completion script uses the '-o nospace' option to prevent bash from
automatically appending a space to unique completions, and it has the
__gitcomp() function to add that trailing space only when necessary.
See 72e5e989 (bash: Add space after unique command name is completed.,
2007-02-04), 78d4d6a2 (bash: Support unique completion on git-config.,
2007-02-04), and b3391775 (bash: Support unique completion when
possible., 2007-02-04).

__gitcomp() therefore iterates over all possible completion words it
got as argument, and checks each word whether a trailing space is
necessary or not.  This is ok for commands, options, etc., i.e. when
the number of words is relatively small, but can be noticeably slow
for large number of refs.  However, while options might or might not
need that trailing space, refs are always handled uniformly and always
get that trailing space (or a trailing '.' for 'git config
branch.<head>.').  Since refs listed by __git_refs() & co. are
separated by newline, this allows us some optimizations with
'compgen'.

So, add a specialized variant of __gitcomp() that only deals with
possible completion words separated by a newline and uniformly appends
the trailing space to all words using 'compgen -S " "' (or any other
suffix, if specified), so no iteration over all words is needed.  But
we need to fiddle with IFS, because the default IFS containing a space
would cause the added space suffix to be stripped off when compgen's
output is stored in the COMPREPLY array.  Therefore we use only
newline as IFS, hence the requirement for the newline-separated
possible completion words.

Convert all callsites of __gitcomp() where it's called with refs, i.e.
when it gets the output of either __git_refs(), __git_heads(),
__git_tags(), __git_refs2(), __git_refs_remotes(), or the odd 'git
for-each-ref' somewhere in _git_config().  Also convert callsites
where it gets other uniformly handled newline separated word lists,
i.e. either remotes from __git_remotes(), names of set configuration
variables from __git_config_get_set_variables(), stashes, or commands.

Here are some timing results for dealing with 10000 refs.
Before:

  $ refs="$(__git_refs ~/tmp/git/repo-with-10k-refs/)"
  $ time __gitcomp "$refs"

  real	0m1.134s
  user	0m1.060s
  sys	0m0.130s

After:

  $ time __gitcomp_nl "$refs"

  real	0m0.373s
  user	0m0.360s
  sys	0m0.020s
