84b4202d80 status/commit: make sure --porcelain is not affected by user-facing config
The recent addition of status.branch started affecting what is shown
when "git status --porcelain" is run by mistake.  Identify the
configuration items that should be ignored under "--porcelain"
option, introduce a "deferred config" mechanism to keep the values
read from the configuration, and decide what value to use only after
we read both from configuration and command line.

f0915cbaf4 commit: make it work with status.short
With "status.short" set, it is now impossible to commit with
status.short set, because it acts like "git commit --short", and it
is impossible to differentiate between a status_format set by the
command-line option parser versus that set by the config parser.

To alleviate this problem, clear status_format as soon as the config
parser has finished its work.

ed2b18292b push: change simple to accommodate triangular workflows
When remote.pushdefault or branch.<name>.pushremote is set to a
remote that is different from where you usually fetch from (i.e. a
triangular workflow), master@{u} != origin, and push.default is set
to `upstream` or `simple` would fail with this error:

  $ git push
  fatal: You are pushing to remote 'origin', which is not the upstream of
  your current branch 'master', without telling me what to push
  to update which remote branch.

The very name of "upstream" indicates that it is only suitable for
use in central workflows; let us not even attempt to give it a new
meaning in triangular workflows, and error out as before.

However, the `simple` does not have to share this error.  It is
poised to be the default for Git 2.0, and we would like it to do
something sensible in triangular workflows.

Redefine "simple" as "safer upstream" for centralized workflow as
before, but work as "current" for triangular workflow.

We may want to make it "safer current", but that is a separate
issue.

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.

When describing a detached HEAD according to the $GIT_PS1_DESCRIBE

Obviously, this neither respects core.abbrev nor produces a unique

26cd160cb1 rebase -i: use a better reflog message
Now that the "checkout" invoked internally from "rebase -i" knows to

etc. internally checks out the new fork point.  We will write:

  rebase -i: checkout master

instead of the old

As all the calls git-rebase--interactive make to underlying git
commands that leave reflog messages are preceded by the internal
comment_for_reflog helper function, which uses the original value of
the GIT_REFLOG_ACTION variable it saw when it first started, the new
assignments to GIT_REFLOG_ACTION actively contaminate the value of
the variable, knowing that it will be reset to a sane value before
it is used again.  This does not generally hold true but it should
suffice for now.

e5c2909782 add -i: add extra options at the right place in "diff" command line
Appending "--diff-algorithm=histogram" at the end of canned command
line for various modes of "diff" is correct for most of them but not
for "stash" that has a non-option already wired in, like so:

	'stash' => {
		DIFF => 'diff-index -p HEAD',

Appending an extra option after non-option may happen to work due to
overly lax command line parser, but that is not something we should
rely on.  Instead, splice in the extra argument immediately after the
command name (i.e. 'diff-index', 'diff-files', etc.).

ad0e623332 test-lib: support running tests under valgrind in parallel
With the new --valgrind-parallel=<n> option, we support running the
tests in a single test script under valgrind in parallel using 'n'
processes.

This really follows the dumbest approach possible, as follows:

* We spawn the test script 'n' times, using a throw-away
  TEST_OUTPUT_DIRECTORY.  Each of the instances is given options that
  ensures that it only runs every n-th test under valgrind, but
  together they cover the entire range.

* We add up the numbers from the individual tests, and provide the
  usual output.

This is really a gross hack at this point, and should be improved.  In
particular we should keep the actual outputs somewhere more easily
discoverable, and summarize them to the user.

Nevertheless, this is already workable and gives a speedup of more
than 2 on a dual-core (hyperthreaded) machine, using n=4.  This is
expected since the overhead of valgrind is so big (on the order of 20x
under good conditions, and a large startup overhead at every git
invocation) that redundantly running the non-valgrind tests in between
is not that expensive.

e939e15d24 test-lib: allow prefixing a custom string before "ok N" etc.
This is not really meant for external use, and thus not documented. It
allows the next commit to neatly distinguish between sub-tests and the
main run.

The format is intentionally not valid TAP.  The use in the next commit
would not result in anything valid either way, and it seems better to
make it obvious.

5dfc368f5e test-lib: valgrind for only tests matching a pattern
With the new --valgrind-only=<pattern> option, one can enable
--valgrind at a per-test granularity, exactly analogous to
--verbose-only from the previous commit.

The options are wired such that --valgrind implies --verbose (as
before), but --valgrind-only=<pattern> implies
--verbose-only=<pattern> unless --verbose is also in effect.

ff09af3fb8 test-lib: verbose mode for only tests matching a pattern
With the new --verbose-only=<pattern> option, one can enable --verbose
at a per-test granularity.  The pattern is matched against the test
number, e.g.

  ./t0000-basic.sh --verbose-only='2[0-2]'

to see only the full output of test 20-22, while showing the rest in the
one-liner format.

As suggested by Jeff King, this takes care to wrap the entire
test_expect_* block, but nothing else, in the verbose toggling.  We
can use the test_start/end functions from the previous commit for the
purpose.

This is arguably not *too* useful on its own, but makes the next patch
easier to follow.

517cd55fd5 test-lib: self-test that --verbose works
t0000 contains some light self-tests of test-lib.sh, but --verbose was
not covered.  Add a test.

The only catch is that the presence of a test harness influences the
output (specifically, the presence of some empty lines).  So we need
to unset TEST_HARNESS or set it to a known value.  Leaving it unset
leads to spurious test failures in the final summary, which come from
the subtest.  So we always set it.
