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.

__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:

user 0m0.495s
sys 0m1.767s
After:
real 0m0.717s

sys 0m0.300s
After, from $PROMPT_COMMAND:
real 0m0.577s
user 0m0.047s

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:

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.

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.

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 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.
Signed-off-by: SZEDER Gábor <szeder@ira.uka.de>
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.
Signed-off-by: SZEDER Gábor <szeder@ira.uka.de>
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.

__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.

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.

__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.

This reverts commit 1a22bd31f0, reversing
changes made to 3e7a5b489e.
It makes it impossible to "git commit" when status.short is set, and
also "git status --porcelain" output is affected by status.branch.
Now that the "checkout" invoked internally from "rebase -i" knows to
honor GIT_REFLOG_ACTION, we can start to use it to write a better
reflog message when "rebase anotherbranch", "rebase --onto branch",
etc. internally checks out the new fork point. We will write:
rebase -i: checkout master
instead of the old
rebase -i
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.

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.
