In 3bf7886 (test-lib: Let tests specify commands to be run at end of
test, 2010-05-02), the git test harness learned to run cleanup
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.
Thanks to Jeff King for the explanation.

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

Most of these tests are removing files, environment variables, and
configuration that might interfere outside the test. Putting these
clean-up commands in the test (in the same spirit as v1.7.1-rc0~59,
2010-03-20) means that errors during setup will be caught quickly and
non-error text will be suppressed without -v.
While at it, apply some other minor fixes:
- do not rely on the shell to export variables defined with the same
command as a function call
- avoid whitespace immediately after the > redirection operator, for
consistency with the style of other tests

Refuse to use $VISUAL and fall back to $EDITOR if TERM is unset

editor and EDITOR to a line-based editor, which should be more
useful in that situation.
vim, for example, is happy to assume a terminal supports ANSI
sequences even if TERM is dumb (e.g., when running from a text
editor like Acme). git already refuses to fall back to vi on a
dumb terminal if GIT_EDITOR, core.editor, VISUAL, and EDITOR are

The tests generate a large amount of I/O activity creating
and destroying repositories and files. We can improve the
time it takes to run the test suite by creating trash
directories on filesystems with better performance
characteristic, even though we may not want the rest of the
git repository on those filesystems (e.g., because they are
not network connected, or because they are temporary
ramdisks).
For example, on a dual processor system:
$ cd t && time make -j32
real 1m51.562s
user 0m59.260s
sys 1m20.933s
# /dev/shm is tmpfs
$ cd t && time make -j32 GIT_TEST_OPTS="--root=/dev/shm"
real 1m1.484s
user 0m53.555s
sys 1m5.264s

dual processors much better.

The test verifies that glob special characters can be escaped with

On Windows, this does not work because backslashes are first of all

Many tests depend on that symbolic links work. This introduces a check
that sets the prerequisite tag SYMLINKS if the file system supports
symbolic links. Since so many tests have to check for this prerequisite,
we do the check in test-lib.sh, so that we don't need to repeat the test
in many scripts.
To check for 'ln -s' failures, you can use a FAT partition on Linux:
$ mkdosfs -C git-on-fat 1000000
$ sudo mount -o loop,uid=j6t,gid=users,shortname=winnt git-on-fat /mnt
Clone git to /mnt and

Linux does not provide.)

Some tests can be run only if a particular prerequisite is available. For
example, some tests require that an UTF-8 locale is available. Here we
introduce functions that are used in this way:
1. Insert code that checks whether the prerequisite is available. If it is,
call test_set_prereq with an arbitrary tag name that subsequently can be
used to check for the prerequisite:
case $LANG in
*.utf-8)
test_set_prereq UTF8
;;
esac
2. In the calls to test_expect_success pass the tag name:
test_expect_success UTF8 '...description...' '...tests...'
3. There is an auxiliary predicate that can be used anywhere to test for
a prerequisite explicitly:
if test_have_prereq UTF8
then
...code to be skipped if prerequisite is not available...

Many tests pass $(pwd) in some form to git and later test that the output
of git contains the correct value of $(pwd). For example, the test of
'git remote show' sets up a remote that contains $(pwd) and then the
expected result must contain $(pwd).
Again, MSYS-bash's path mangling kicks in: Plain $(pwd) uses the MSYS style
absolute path /c/path/to/git. The test case would write this name into
the 'expect' file. But when git is invoked, MSYS-bash converts this name to
the Windows style path c:/path/to/git, and git would produce this form in
the result; the test would fail.
We fix this by passing -W to bash's pwd that produces the Windows-style
path.
There are a two cases that need an accompanying change:
- In t1504 the value of $(pwd) becomes part of a path list. In this case,
the lone 'c' in something like /foo:c:/path/to/git:/bar inhibits
MSYS-bashes path mangling; IOW in this case we want the /c/path/to/git
form to allow path mangling. We use $PWD instead of $(pwd), which always
has the latter form.
- In t6200, $(pwd) - the Windows style path - must be used to construct the
expected result because that is the path form that git sees. (The change
in the test itself is just for consistency: 'git fetch' always sees the
Windows-style path, with or without the change.)

This function replaces sequences of 'chmod +x' and 'git update-index
--chmod=+x' in the test suite, whose purpose is to help filesystems
that need core.filemode=false. Two places where only 'chmod +x' was used
we also use this new function.
The function calls 'git update-index --chmod' without checking
core.filemode (unlike some of the call sites did). We do this because the
call sites *expect* that the executable bit ends up in the index (ie. it
is not the purpose of the call sites to *test* whether git treats
'chmod +x' and 'update-index --chmod=+x' correctly). Therefore, on
filesystems with core.filemode=true the 'git update-index --chmod' is a
no-op.
The function uses --add with update-index to help one call site in
t6031-merge-recursive. It makes no difference for the other callers.
