add-interactive: Clarify “remaining hunks in the file”

The "a" and "d" commands to ‘add --patch’ (accept/reject rest of file)
interact with "j", "g", and "/" (skip some hunks) in a perhaps
confusing way: after accepting or rejecting all _later_ hunks in the
file, they return to the earlier, skipped hunks and prompt the user
about them again.

This behavior can be very useful in practice.  One can still accept or
reject _all_ undecided hunks in a file by using the "g" command to
move to hunk #1 first.

handle "git --bare init <dir>" properly

If we know we are creating a bare repository, we use setenv
to set the GIT_DIR directory to the current directory
(either where we already were, or one we created and chdir'd
into with "git init --bare <dir>").

However, with "git --bare init <dir>" (note the --bare as a
git wrapper option), the setup code actually sets GIT_DIR
for us, but it uses the wrong, original cwd when a directory
is given. Because our setenv does not use the overwrite
flag, it is ignored.

We need to set the overwrite flag, but only when we are
given a directory on the command line. That still allows:

  GIT_DIR=foo.git git init --bare

to work. The behavior is changed for:

  GIT_DIR=foo.git git init --bare bar.git

which used to create the repository in foo.git, but now will
use bar.git. This is more sane, as command line options
should generally override the environment.

In 3bf7886 (test-lib: Let tests specify commands to be run at end of

commands unconditionally at the end of a test.  During each test,
the intended cleanup actions are collected in the test_cleanup variable
and evaluated.  That variable looks something like this:

eval_ret=$?; clean_something && (exit "$eval_ret")
eval_ret=$?; clean_something_else && (exit "$eval_ret")
eval_ret=$?; final_cleanup && (exit "$eval_ret")
eval_ret=$?

All cleanup actions are run unconditionally but if one of them fails
it is properly reported through $eval_ret.

On FreeBSD, unfortunately, $? is set at the beginning of an ‘eval’
to 0 instead of the exit status of the previous command.  This results
in tests using test_expect_code appearing to fail and all others
appearing to pass, unless their cleanup fails.  Avoid the problem by
setting eval_ret before the ‘eval’ begins.

Documentation/shortlog: scripted users should not rely on implicit HEAD

When passed no revision arguments, ‘git shortlog’ reads a log from
stdin if and only if stdin is not a tty.  So scripts that need to
function identically when standard input is a terminal (as when run
interactively) and not (as when run through a cron job) should either
supply a log themselves or specify the desired revisions explicitly.

11 years agotest-lib: Let tests specify commands to be run at end of test

test-lib: Let tests specify commands to be run at end of test

Certain actions can imply that if the test fails early, recovery from
within other tests is too much to expect:

 - creating unwritable directories, like the EACCESS test in t0001-init
 - setting unusual configuration, like user.signingkey in t7004-tag
 - crashing and leaving the index lock held, like t3600-rm once did

Some test scripts work around this by running cleanup actions outside
the supervision of the test harness, with the unfortunate consequence
that those commands are not appropriately echoed and their output not
suppressed.  Others explicitly save exit status, clean up, and then
reset the exit status within the tests, which has excellent behavior
but makes the tests hard to read.  Still others ignore the problem.

Allow tests a fourth option: by calling this function, tests can
stack up commands they would like to be run to clean up.

Commands passed to test_when_finished during a test are
unconditionally run in the test environment immediately before the
test is completed, in last-in-first-out order.  If some cleanup
command fails, then the other cleanup commands are still run before
the failure is reported and the test script allowed to continue.

Dear Junio,

this is a resend of relicensing patch for test suite library, which
was initially sent by Carl Worth. Since the time you sent me acks for
this patch collected by you, I collected 8 additional acks as is
documented at
https://git.wiki.kernel.org/index.php/Test-lib_reclicensing. There are
still three contributors missing: Bert Wesarg, Stephan Beyer and Bryan
Donlan. The contributions of first two are clearly not copyrightable.
I'm not sure about the copyrightability of Bryan Donlan's
contributions (git log -p --author='Bryan Donlan' t/test-lib.sh).

Carl told me that in your ack collection process you missed only three
acks. So I wonder whether you already did some analysis of which
contributions are copyrightable. If so, are the missing acks in the
list bellow?

Thanks
Michal

René Scharfe [Sun, 2 May 2010 13:04:41 +0000 (15:04 +0200)]
git diff too slow for a file

Ever since the xdiff library had been introduced to git, all its callers
have used the flag XDF_NEED_MINIMAL.  It makes sure that the smallest
possible diff is produced, but that takes quite some time if there are
lots of differences that can be expressed in multiple ways.

This flag makes a difference for only 0.1% of the non-merge commits in
the git repo of Linux, both in terms of diff size and execution time.
The patches there are mostly nice and small.

SungHyun Nam however reported a case in a different repo where a diff
took more than 20 times longer to generate with XDF_NEED_MINIMAL than
without.  Rebasing became really slow.

This patch removes this flag from all callers.  The default of xdiff is
saner because it has minimal to no impact in the normal case of small
diffs and doesn't incur that much of a speed penalty for large ones.

A follow-up patch may introduce a command line option to set the flag if
the user needs it, similar to GNU diff's -d/--minimal.
