'git -C <path>' option(s) on the command line should be taken into
account during completion, because
- like '--git-dir=<path>', it can lead us to a different repository,
- a few git commands executed in the completion script do care about
in which directory they are executed, and
- the command for which we are providing completion might care about
in which directory it will be executed.
However, unlike '--git-dir=<path>', the '-C <path>' option can be
specified multiple times and their effect is cumulative, so we can't
just store a single '<path>' in a variable. Nor can we simply
concatenate a path from '-C <path1> -C <path2> ...', because e.g. (in
an arguably pathological corner case) a relative path might be
followed by an absolute path.
Instead, store all '-C <path>' options word by word in the
$__git_C_args array in the main git completion function, and pass this
array, if present, to 'git rev-parse --absolute-git-dir' when
discovering the repository in __gitdir(), and let it take care of
multiple options, relative paths, absolute paths and everything.
Also pass all '-C <path> options via the $__git_C_args array to those
git executions which require a worktree and for which it matters from
which directory they are executed from. There are only three such
cases:
- 'git diff-index' and 'git ls-files' in __git_ls_files_helper()
used for git-aware filename completion, and
- the 'git ls-tree' used for completing the 'ref:path' notation.
The other git commands executed in the completion script don't need
these '-C <path>' options, because __gitdir() already took those
options into account. It would not hurt them, either, but let's not
induce unnecessary code churn.

The output of 'git rev-parse --git-dir' can be either a relative or an
absolute path, depending on whether the current working directory is
at the top of the worktree or the .git directory or not, or how the
path to the repository is specified via the '--git-dir=<path>' option
or the $GIT_DIR environment variable. And if that output is a
relative path, then it is relative to the directory where any 'git
-C <path>' options might have led us.
This doesn't matter at all for regular scripts, because the git
wrapper automatically takes care of changing directories according to
the '-C <path>' options, and the scripts can then simply follow any
path returned by 'git rev-parse --git-dir', even if it's a relative
path.
Our Bash completion script, however, is unique in that it must run
directly in the user's interactive shell environment. This means that
it's not executed through the git wrapper and would have to take care
of any '-C <path> options on its own, and it can't just change
directories as it pleases. Consequently, adding support for taking
any '-C <path>' options on the command line into account during
completion turned out to be considerably more difficult, error prone
and required more subshells and git processes when it had to cope with
a relative path to the .git directory.
Help this rather special use case and teach 'git rev-parse' a new
'--absolute-git-dir' option which always outputs a canonicalized
absolute path to the .git directory, regardless of whether the path is
discovered automatically or is specified via $GIT_DIR or 'git
--git-dir=<path>'.

The main completion function finds the name of the git command by
iterating through all the words on the command line in search for the
first non-option-looking word. As it is not aware of 'git -C's
mandatory path argument, if the '-C <path>' option is present, 'path'
will be the first such word and it will be mistaken for a git command.
This breaks completion in various ways:
- If 'path' happens to match one of the commands supported by the
completion script, then options of that command will be offered.
- If 'path' doesn't match a supported command and doesn't contain any
characters not allowed in Bash identifier names, then the
completion script does basically nothing and Bash in turn falls
back to filename completion for all subsequent words.
- Otherwise, if 'path' does contain such an unallowed character, then
it leads to a more or less ugly error message in the middle of the
command line. The standard '/' directory separator is such a
character, and it happens to trigger one of the uglier errors:
$ git -C some/path <TAB>sh.exe": declare: `_git_some/path': not a valid identifier
error: invalid key: alias.some/path
Fix this by skipping 'git -C's mandatory path argument while iterating
over the words on the command line. Extend the relevant test with
this case and, while at it, with cases that needed similar treatment
in the past ('--git-dir', '-c', '--work-tree' and '--namespace').
Additionally, silence the standard error of the 'declare' builtins
looking for the completion function associated with the git command
and of the 'git config' query for the aliased command. So if git ever
learns a new option with a mandatory argument in the future, then,
though the completion script will again misbehave, at least the
command line will not be utterly disrupted by those error messages.

completion: don't offer commands when 'git --opt' needs an argument
The main git options '--git-dir', '-c', '-C', '--worktree' and
'--namespace' require an argument, but attempting completion right
after them lists git commands.
Don't offer anything right after these options, thus let Bash fall
back to filename completion, because
- the three options '--git-dir', '-C' and '--worktree' do actually
require a path argument, and
- we don't complete the required argument of '-c' and '--namespace',
and in that case the "standard" behavior of our completion script
is to not offer anything, but fall back to filename completion.

completion: list short refs from a remote given as a URL
e832f5c09680 (completion: avoid ls-remote in certain scenarios,
2013-05-28) turned a 'git ls-remote <remote>' query into a 'git
for-each-ref refs/remotes/<remote>/' to improve responsiveness of
remote refs completion by avoiding potential network communication.
However, it inadvertently made impossible to complete short refs from
a remote given as a URL, e.g. 'git fetch git://server.com/repo.git
<TAB>', because there is, of course, no such thing as
'refs/remotes/git://server.com/repo.git'.
Since the previous commit we tell apart configured remotes, i.e. those
that can have a hierarchy under 'refs/remotes/', from others that
don't, including remotes given as URL, so we know when we can't use
the faster 'git for-each-ref'-based approach.
Resurrect the old, pre-e832f5c09680 'git ls-remote'-based code for the
latter case to support listing short refs from remotes given as a URL.
The code is slightly updated from the original to
- take into account the path to the repository given on the command
line (if any), and
- omit 'ORIG_HEAD' from the query, as 'git ls-remote' will never
list it anyway.
When the remote given to __git_refs() doesn't exist, then it will be
handled by this resurrected 'git ls-remote' query. This code path
doesn't list 'HEAD' unconditionally, which has the nice side effect of
fixing two more expected test failures.

completion: list refs from remote when remote's name matches a directory
If the remote given to __git_refs() happens to match both the name of
a configured remote and the name of a directory in the current working
directory, then that directory is assumed to be a git repository, and
listing refs from that directory will be attempted. This is wrong,
because in such a situation git commands (e.g. 'git fetch|pull|push
<remote>' whom these refs will eventually be passed to) give
precedence to the configured remote. Therefore, __git_refs() should
list refs from the configured remote as well.
Add the helper function __git_is_configured_remote() that checks
whether its argument matches the name of a configured remote. Use
this helper to decide how to handle the remote passed to __git_refs().

completion: respect 'git --git-dir=<path>' when listing remote refs
In __git_refs() the git commands listing refs, both short and full,
from a given remote repository are run without giving them the path to
the git repository which might have been specified on the command line
via 'git --git-dir=<path>'. This is bad, those git commands should
access the 'refs/remotes/<remote>/' hierarchy or the remote and
credentials configuration in that specified repository.
Use the __gitdir() helper only to find the path to the .git directory
and pass the resulting path to the 'git ls-remote' and 'for-each-ref'
executions that list remote refs. While modifying that 'for-each-ref'
line, remove the superfluous disambiguating doubledash.
Don't use __gitdir() to check that the given remote is on the file
system: basically it performs only a single if statement for us at the
considerable cost of fork()ing a subshell for a command substitution.
We are better off to perform all the necessary checks of the remote in
__git_refs().
Though __git_refs() was the last remaining callsite that passed a
remote to __gitdir(), don't delete __gitdir()'s remote-handling part
yet, just in case some users' custom completion scriptlets depend on
it.

completion: ensure that the repository path given on the command line exists
The __gitdir() helper function prints the path to the git repository
to its stdout or stays silent and returns with error when it can't
find a repository or when the repository given via $GIT_DIR doesn't
exist.
This is not the case, however, when the path in $__git_dir, i.e. the
path to the repository specified on the command line via 'git
--git-dir=<path>', doesn't exist: __gitdir() still outputs it as if it
were a real existing repository, making some completion functions
believe that they operate on an existing repository.

completion tests: add tests for the __git_refs() helper function
Check how __git_refs() lists refs in different scenarios, i.e.

- non-existing remote,
- unique remote branches for 'git checkout's tracking DWIMery,

Seven of these tests expect failure, mostly demonstrating bugs related
to listing refs from a remote repository:

- listing refs from the wrong place when the name of a configured

completion tests: consolidate getting path of current working directory
Some tests of the __gitdir() helper function use the $TRASH_DIRECTORY

avoided, because it might contain symbolic links. There happens to be
no issues with this here, however, because those tests use
$TRASH_DIRECTORY both for specifying the expected result and for
specifying input which in turn is just 'echo'ed verbatim.
Other __gitdir() tests ask for the path of the trash directory by
running $(pwd -P) in each test, sometimes even twice in a single test.
Run $(pwd) only once at the beginning of the test script to store the
path of the trash directory in a variable, and use that variable in
all __gitdir() tests.

completion tests: make the $cur variable local to the test helper functions
The test helper functions test_gitcomp() and test_gitcomp_nl() leak
the $cur variable into the test environment. Since this variable has
a special role in the Bash completion script (it holds the word
currently being completed) it influences the behavior of most
completion functions and thus this leakage could interfere with
subsequent tests. Although there are no such issues in the current
tests, early versions of the new tests that will be added later in
this series suffered because of this.
It's better to play safe and declare $cur local in those test helper
functions. 'local' is bashism, of course, but the tests of the Bash
completion script are run under Bash anyway, and there are already
other variables declared local in this test script.

Prior to c2f41bf52 (color.c: fix color_parse_mem() with
value_len == 0, 2017-01-19), the empty string was
interpreted as a color "reset". This was an accidental
outcome, and that commit turned it into an error.
However, scripts may pass the empty string as a default
value to "git config --get-color" to disable color when the
value is not defined. The git-add--interactive script does
this. As a result, the script is unusable since c2f41bf52
unless you have color.diff.plain defined (if it is defined,
then we don't parse the empty default at all).
Our test scripts didn't notice the recent breakage because
they run without a terminal, and thus without color. They
never hit this code path at all. And nobody noticed the
original buggy "reset" behavior, because it was effectively
a noop.
Let's fix the code to have an empty color name produce an
empty sequence of color codes. The tests need a few fixups:
- we'll add a new test in t4026 to cover this case. But
note that we need to tweak the color() helper. While
we're there, let's factor out the literal ANSI ESC
character. Otherwise it makes the diff quite hard to
read.
- we'll add a basic sanity-check in t4026 that "git add
-p" works at all when color is enabled. That would have
caught this bug, as well as any others that are specific
to the color code paths.
- 73c727d69 (log --graph: customize the graph lines with
config log.graphColors, 2017-01-19) added a test to
t4202 that checks some "invalid" graph color config.
Since ",, blue" before yielded only "blue" as valid, and
now yields "empty, empty, blue", we don't match the
expected output.
One way to fix this would be to change the expectation
to the empty color strings. But that makes the test much
less interesting, since we show only two graph lines,
both of which would be colorless.
Since the empty-string case is now covered by t4026,
let's remove them entirely here. They're just in the way
of the primary thing the test is supposed to be
checking.

The default behavior of update-ref to create reflogs differs in
repositories with worktree and bare ones. The existing tests cover only
the behavior of repositories with worktree.
This commit adds tests that assert the correct behavior in bare
repositories for update-ref. Two cases are covered:
- If core.logAllRefUpdates is not set, no reflogs should be created
- If core.logAllRefUpdates is true, reflogs should be created

When core.logallrefupdates is true, we only create a new reflog for refs
that are under certain well-known hierarchies. The reason is that we
know that some hierarchies (like refs/tags) are not meant to change, and
that unknown hierarchies might not want reflogs at all (e.g., a
hypothetical refs/foo might be meant to change often and drop old
history immediately).
However, sometimes it is useful to override this decision and simply log
for all refs, because the safety and audit trail is more important than
the performance implications of keeping the log around.
This patch introduces a new "always" mode for the core.logallrefupdates
option which will log updates to everything under refs/, regardless
where in the hierarchy it is (we still will not log things like
ORIG_HEAD and FETCH_HEAD, which are known to be transient).

t0001: don't let a default ACL interfere with the umask test
The "init creates a new deep directory (umask vs. shared)" test expects
the permissions of newly created files to be based on the umask, which
fails if a default ACL is inherited from the working tree for git. So
attempt to remove a default ACL if there is one. Same idea as 8ed0a740dd42bd0724aebed6e3b07c4ea2a2d5e8. (I guess I'm the only one who
ever runs the test suite with a default ACL set.)

When running git-p4 on Windows, with multiple git-p4.mapUser entries in
git config - no user mappings are applied to the generated repository.
Reproduction Steps:
1. Add multiple git-p4.mapUser entries to git config on a Windows
machine
2. Attempt to clone a p4 repository
None of the user mappings will be applied.
This issue is actually caused by gitConfigList, using split(os.linesep)
to convert the output of git config --get-all into a list. On Windows,
os.linesep is equal to '\r\n' - however git.exe returns configuration
with a line seperator of '\n'.
This leads to the list returned by gitConfigList containing only one
element - which contains the full output of git config --get-all in
string form, which causes problems for the code introduced to
getUserMapFromPerforceServer in 10d08a149d ("git-p4: map a P4 user to
Git author name and email address", 2016-03-01)
This issue should be caught by the test introduced in 10d08a1, however
would require running on Windows to reproduce.
Using splitlines solves this issue, by splitting config on all
typical delimiters ('\n', '\r\n' etc.)

On Windows, executables need to have the file extension `.exe`, or they
are not executables. Hence, to support scripts, Git for Windows also
looks for a she-bang line by opening the file in question, and executing
it via the specified script interpreter.
To figure out whether files in the `PATH` are executable, `git help` has
code that imitates this behavior. With one exception: it *always* opens
the files and looks for a she-bang line *or* an `MZ` tell-tale
(nevermind that files with the magic `MZ` but without file extension
`.exe` would still not be executable).
Opening this many files leads to performance problems that are even more
serious when a virus scanner is running. Therefore, let's change the
code to look for the file extension `.exe` early, and avoid opening the
file altogether if we already know that it is executable.
See the following measurements (in seconds) as an example, where we
execute a simple program that simply lists the directory contents and
calls open() on every listed file:
With virus scanner running (coldcache):
$ ./a.exe /libexec/git-core/
before open (git-add.exe): 0.000000
after open (git-add.exe): 0.412873
before open (git-annotate.exe): 0.000175

With this patch I get:
$ time git help git

and without
$ time git help git

real 1m37.734s
user 0m0.000s

both tests with cold cache and giving the machine some time to settle
down after restart.
