The next commit will tweak the way __git_ps1() decides whether to display
the untracked files status indicator in the presence of untracked
directories. Add tests to make sure it doesn't change current behavior,
in particular that an empty untracked directory doesn't trigger the
untracked files status indicator.

People often forget to chain the commands in their test together
with &&, leaving a failure from an earlier command in the test go
unnoticed. The new GIT_TEST_CHAIN_LINT mechanism allows you to

The prompt script (in contrib/) did not show the untracked sign
when working in a subdirectory without any untracked files.
* ct/prompt-untracked-fix:
git prompt: use toplevel to find untracked files

These are tests which are missing a link in their &&-chain,
but during a setup phase. We may fail to notice failure in
commands that build the test environment, but these are
typically not expected to fail at all (but it's still good
to double-check that our test environment is what we
expect).

Optionally set __git_ps1 to display nothing when present working
directory is ignored, triggered by the new environment variable
GIT_PS1_HIDE_IF_PWD_IGNORED. This environment variable may be
overridden on any repository by setting bash.hideIfPwdIgnored to
"false". In the absence of GIT_PS1_HIDE_IF_PWD_IGNORED this change
has no effect.
Many people manage e.g. dotfiles in their home directory with git.
This causes the prompt generated by __git_ps1 to refer to that "top
level" repo while working in any descendant directory. That can be
distracting, so this patch helps one shut off that noise.

Not all shells subject the prompt string to parameter expansion. Test
whether the shell will expand the value of PS1, and use the result to
control whether raw ref names are included directly in PS1.
This fixes a regression introduced in commit 8976500 ("git-prompt.sh:
don't put unsanitized branch names in $PS1"): zsh does not expand PS1
by default, but that commit assumed it did. The bug resulted in
prompts containing the literal string '${__git_ps1_branch_name}'
instead of the actual branch name.

Both bash and zsh subject the value of PS1 to parameter expansion,
command substitution, and arithmetic expansion. Rather than include
the raw, unescaped branch name in PS1 when running in two- or
three-argument mode, construct PS1 to reference a variable that holds
the branch name. Because the shells do not recursively expand, this
avoids arbitrary code execution by specially-crafted branch names such
as '$(IFS=_;cmd=sudo_rm_-rf_/;$cmd)'.

Newlines in the path to a git repository were not an issue for the
git-specific bash prompt before commit efaa0c1532 (bash prompt:
combine 'git rev-parse' executions in the main code path, 2013-06-17),
because the path returned by 'git rev-parse --git-dir' was directly
stored in a variable, and this variable was later always accessed
inside double quotes.
Newlines are not an issue after commit efaa0c1532 either, but it's
more subtle. Since efaa0c1532 we use the following single 'git
rev-parse' execution to query various info about the repository:
git rev-parse --git-dir --is-inside-git-dir \
--is-bare-repository --is-inside-work-tree
The results to these queries are separated by a newline character in
the output, e.g.:
/home/szeder/src/git/.git
false
false
true
A newline in the path to the git repository could potentially break
the parsing of these results and ultimately the bash prompt, unless
the parsing is done right. Commit efaa0c1532 got it right, as I
consciously started parsing 'git rev-parse's output from the end,
where each record is a single line containing either 'true' or 'false'
or, after e3e0b9378b (bash prompt: combine 'git rev-parse' for
detached head, 2013-06-24), the abbreviated commit object name, and
all what remains at the beginning is the path to the git repository,
no matter how many lines it is.
This subtlety really warrants its own test, especially since I didn't
explain it in the log message or in an in-code comment back then, so
add a test to excercise the prompt with newline characters in the path
to the repository. Guard this test with the FUNNYNAMES prerequisite,
because not all filesystems support newlines in filenames. Note that
'git rev-parse --git-dir' prints '.git' or '.' when at the top of the
worktree or the repository, respectively, and only prints the full
path to the repository when in a subdirectory, hence the need for
changing into a subdir in the test.

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.

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.

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.

Currently __gitdir() is duplicated in the git completion and prompt
scripts, while its tests are in the prompt test suite. This patch
series is about to change __git_ps1() in a way that it won't need
__gitdir() anymore and __gitdir() will be removed from the prompt
script.
So move all __gitdir() tests from the prompt test suite over to the
completion test suite. Update the setup tests so that they perform
only those steps that are necessary for each test suite.

* zk/prompt-rebase-step:
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.

When the git directory is accessed through a symlink like
ln -s /tmp/git /tmp/git-symlink
cd /tmp/git-symlink/t
make -C .. && ./t9903-bash-prompt.sh
$TRASH_DIRECTORY is /tmp/git-symlink/t/trash directory.t9903-bash-prompt
and $(pwd -P) is /tmp/git/t/trash directory.t9903-bash-prompt.
When __gitdir looks up the path through 'git rev-parse --git-dir', it
will return paths similar to $(pwd -P). This behavior is already tested in
t9903 'gitdir - resulting path avoids symlinks'.

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.

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.

The tests cover the discovery of the '.git' directory in the
__gitdir() function in different scenarios, and the prompt itself,
i.e. branch name, detached heads, operations (rebase, merge,
cherry-pick, bisect), and status indicators (dirty, stash, untracked
files; but not the upstream status).
