As discussed in [1] there's a regression in the "pu" branch now
because a new test implicitly assumed that a previous test guarded by
a prerequisite had been run. Add a "GIT_TEST_FAIL_PREREQS" special
test setup where we'll skip (nearly) all tests guarded by
prerequisites, allowing us to easily emulate those platform where we
don't run these tests.
As noted in the documentation I'm adding I'm whitelisting the SYMLINKS
prerequisite for now. A lot of tests started failing if we lied about
not supporting symlinks. It's also unlikely that we'll have a failing
test due to a hard dependency on symlinks without that being the
obvious cause, so for now it's not worth the effort to make it work.

When running Apache, 'git daemon', or p4d, we want to kill them at the
end of the test script, otherwise a leftover daemon process will keep
its port open indefinitely, and thus will interfere with subsequent
executions of the same test script.
So far, we stop these daemon processes "manually", i.e.:
- by registering functions or commands in the trap on EXIT to stop
the daemon while preserving the last seen exit code before the
trap (to deal with a failure when run with '--immediate' or with
interrupts by ctrl-C),
- and by invoking these functions/commands last thing before
'test_done' (and sometimes restoring the test framework's default
trap on EXIT, to prevent the daemons from being killed twice).
On one hand, we do this inconsistently, e.g. 'git p4' tests invoke
different functions in the trap on EXIT and in the last test before
'test_done', and they neither restore the test framework's default trap
on EXIT nor preserve the last seen exit code. On the other hand, this
is error prone, because, as shown in a previous patch in this series,
any output from the cleanup commands in the trap on EXIT can prevent a
proper cleanup when a test script run with '--verbose-log' and certain
shells, notably 'dash', is interrupted.
Let's introduce 'test_atexit', which is loosely modeled after
'test_when_finished', but has a broader scope: rather than running the
commands after the current test case, run them when the test script
finishes, and also run them when the test is interrupted, or exits
early in case of a failure while the '--immediate' option is in
effect.
When running the cleanup commands at the end of a successful test,
then they will be run in 'test_done' before it removes the trash
directory, i.e. the cleanup commands will still be able to access any
pidfiles or socket files in there. When running the cleanup commands
after an interrupt or failure with '--immediate', then they will be
run in the trap on EXIT. In both cases they will be run in
'test_eval_', i.e. both standard error and output of all cleanup
commands will go where they should according to the '-v' or
'--verbose-log' options, and thus won't cause any troubles when
interrupting a test script run with '--verbose-log'.

Change the GETTEXT_POISON compile-time + runtime GIT_GETTEXT_POISON
test parameter to only be a GIT_TEST_GETTEXT_POISON=<non-empty?>
runtime parameter, to be consistent with other parameters documented
in "Running tests with special setups" in t/README.
When I added GETTEXT_POISON in bb946bba76 ("i18n: add GETTEXT_POISON
to simulate unfriendly translator", 2011-02-22) I was concerned with
ensuring that the _() function would get constant folded if NO_GETTEXT
was defined, and likewise that GETTEXT_POISON would be compiled out
unless it was defined.
But as the benchmark in my [1] shows doing a one-off runtime
getenv("GIT_TEST_[...]") is trivial, and since GETTEXT_POISON was
originally added the GIT_TEST_* env variables have become the common
idiom for turning on special test setups.
So change GETTEXT_POISON to work the same way. Now the
GETTEXT_POISON=YesPlease compile-time option is gone, and running the
tests with GIT_TEST_GETTEXT_POISON=[YesPlease|] can be toggled on/off
without recompiling.
This allows for conditionally amending tests to test with/without
poison, similar to what 859fdc0c3c ("commit-graph: define
GIT_TEST_COMMIT_GRAPH", 2018-08-29) did for GIT_TEST_COMMIT_GRAPH. Do
some of that, now we e.g. always run the t0205-gettext-poison.sh test.
I did enough there to remove the GETTEXT_POISON prerequisite, but its
inverse C_LOCALE_OUTPUT is still around, and surely some tests using
it can be converted to e.g. always set GIT_TEST_GETTEXT_POISON=.
Notes on the implementation:
* We still compile a dedicated GETTEXT_POISON build in Travis
CI. Perhaps this should be revisited and integrated into the
"linux-gcc" build, see ae59a4e44f ("travis: run tests with
GIT_TEST_SPLIT_INDEX", 2018-01-07) for prior art in that area. Then
again maybe not, see [2].
* We now skip a test in t0000-basic.sh under
GIT_TEST_GETTEXT_POISON=YesPlease that wasn't skipped before. This
test relies on C locale output, but due to an edge case in how the
previous implementation of GETTEXT_POISON worked (reading it from
GIT-BUILD-OPTIONS) wasn't enabling poison correctly. Now it does,
and needs to be skipped.
* The getenv() function is not reentrant, so out of paranoia about
code of the form:
printf(_("%s"), getenv("some-env"));
call use_gettext_poison() in our early setup in git_setup_gettext()
so we populate the "poison_requested" variable in a codepath that's
won't suffer from that race condition.
* We error out in the Makefile if you're still saying
GETTEXT_POISON=YesPlease to prompt users to change their
invocation.
* We should not print out poisoned messages during the test
initialization itself to keep it more readable, so the test library
hides the variable if set in $GIT_TEST_GETTEXT_POISON_ORIG during
setup. See [3].
See also [4] for more on the motivation behind this patch, and the
history of the GETTEXT_POISON facility.

The test framework test-lib.sh itself would want to give warnings
and hints, e.g. when it sees a deprecated environment variable is in
use that we want to encourage users to migrate to another variable.
The self-test of test framework done in t0000 however do not expect
to see these warnings and hints, so depending on the settings of
environment variables, a running test may or may not produce these
messages to the standard error output, breaking the expectations of
self-test test framework does on itself. Here is what we see:
$ TEST_GIT_INDEX_VERSION=4 sh t0000-basic.sh -i -v
...
'err' is not empty, it contains:
warning: TEST_GIT_INDEX_VERSION is now GIT_TEST_INDEX_VERSION
hint: set GIT_TEST_INDEX_VERSION too during the transition period
not ok 5 - pretend we have a fully passing test suite
The following quick attempt to work it around does not work, because
some tests in t0000 do want to see expected errors from the test
framework itself.

There are a few possible ways to work this around:
* We could strip the warning: and hint: unconditionally from the
error output before the error messages are checked in the
self-test (helper functions check_sub_test_lib_test_err and
check_sub_test_lib_test); the problem with this approach is that
it will make it impossible to write self-tests to ensure that
right warnings and hints are given.
* We could force a sane environment settings before the test helper
_run_sub_test_lib_test_common dot-sources test-lib.sh; the
problem with this approach is that _run_sub_test_lib_test_common
now needs to be aware of what pairs of environment variables are
checked in test-lib.sh using check_var_migration helper.
The final patch I came up with is probably the solution that is
least bad. Set a variable to tell test-lib.sh that we are running
a self-test, so that various pieces in test-lib.sh can react to keep
the output stable.

Test t0000 tests the "basics of the basics" and as such, checks that we
have various fixed hard-coded object IDs. The tests relying on these
assertions have been marked with the SHA1 prerequisite, as they will
obviously not function in their current form with SHA-256.
Use the test_oid helper to update these assertions and provide values
for both SHA-1 and SHA-256.
These object IDs were synthesized using a set of scripts that created
the objects for both SHA-1 and SHA-256 using the same method to ensure
that they are indeed the correct values.

Add several test functions to make working with various hash-related
values easier.
Add test_oid_init, which loads common hash-related constants and
placeholder object IDs from the newly added files in t/oid-info.
Provide values for these constants for both SHA-1 and SHA-256.
Add test_oid_cache, which accepts data on standard input in the form of
hash-specific key-value pairs that can be looked up later, using the
same format as the files in t/oid-info. Document this format in a
t/oid-info/README directory so that it's easier to use in the future.
Add test_oid, which is used to specify look up a per-hash value
(produced on standard output) based on the key specified as its
argument. Usually the data to be looked up will be a hash-related
constant (such as the size of the hash in binary or hexadecimal), a
well-known or placeholder object ID (such as the all-zeros object ID or
one consisting of "deadbeef" repeated), or something similar. For these
reasons, test_oid will usually be used within a command substitution.
Consequently, redirect the error output to standard error, since
otherwise it will not be displayed.
Add test_detect_hash, which currently only detects SHA-1, and
test_set_hash, which can be used to set a different hash algorithm for
test purposes. In the future, test_detect_hash will learn to actually
detect the hash depending on how the testsuite is to be run.
Use the local keyword within these functions to avoid overwriting other
shell variables. We have had a test balloon in place for a couple of
releases to catch shells that don't have this keyword and have not
received any reports of failure. Note that the varying usages of local
used here are supported by all common open-source shells supporting the
local keyword.
Test these new functions as part of t0000, which also serves to
demonstrate basic usage of them. In addition, add documentation on how
to format the lookup data and how to use the test functions.
Implement two basic lookup charts, one for common invalid or synthesized
object IDs, and one for various facts about the hash function in use.
Provide versions of the data for both SHA-1 and SHA-256.
Since we use shell variables for storage, names used for lookup can
currently consist only of shell identifier characters. If this is a
problem in the future, we can hash the names before use.

tests: use 'test_must_be_empty' instead of 'test ! -s'

Using 'test_must_be_empty' is preferable to '! test -s', because it
gives a helpful error message if the given file is unexpectedly not
empty, while the latter remains completely silent. Furthermore, it
also catches cases when the given file unexpectedly does not exist at
all.
This patch was basically created by:
sed -i -e 's/! test -s/test_must_be_empty/' t[0-9]*.sh
with the following notable exceptions:
- The '! test -s' check in '.gitmodules ignore=dirty suppresses
submodules with untracked content' in 't7508-status.sh' is left
as-is, because it's bogus and, therefore, it's subject of a
dedicated patch.
- The '! test -s' checks in 't9131-git-svn-empty-symlink.sh' and
't9135-git-svn-moved-branch-empty-file.sh' are immediately
preceeded by a 'test -f' to ensure that the files exist in the
first place. 'test_must_be_empty' ensures that as well, so those
'test -f' commands are removed as well.

Having a simulated "known breakage" test means that the test
suite will always tell us there is a bug to be fixed, even
though it is only simulated.
The right way to test this is in a sub-test, that can also
check that we provide the correct exit status and output.
Fortunately, we already have such a test (added much later
by 5ebf89e).
We could arguably get rid of the simulated success test
immediately above, as well, as it is also redundant with the
tests added in 5ebf89e. However, it does not have the
annoying behavior of the "known breakage" test. It may also
be easier to debug if the test suite is truly broken, since
it is not a test-within-a-test, as the later tests are.

Commit 517cd55 set HARNESS_ACTIVE unconditionally in
sub-tests, because that value affects the output of
"--verbose". t0000 needs stable output from its sub-tests,
and we may or may not be running under a TAP harness.
That commit made the decision to always set the variable,
since it has another useful side effect, which is
suppressing writes to t/test-results by the sub-tests (which
would just pollute the real results).
Since the last commit, though, the sub-tests have their own
test-results directories, so this is no longer an issue. We
can now update a few comments that are no longer accurate
nor necessary.
We can also revisit the choice of HARNESS_ACTIVE. Since we
must choose one value for stability, it's probably saner to
have it off. This means that future patches could test
things like the test-results writing, or the "--quiet"
option, which is currently ignored when run under a harness.

Running t0000 produces more trash directories than expected and does
not clean up after itself:
$ ./t0000-basic.sh
[...]
$ ls -d trash\ directory.*
trash directory.failing-cleanup
trash directory.mixed-results1
trash directory.mixed-results2
trash directory.partial-pass
trash directory.test-verbose
trash directory.test-verbose-only-2
These scratch areas for sub-tests should be under the t0000 trash
directory, but because TEST_OUTPUT_DIRECTORY defaults to
TEST_DIRECTORY, which is exported to help sub-tests find
test-lib.sh, the sub-test trash directories are created under the
toplevel t/ directory instead. Because some of the sub-tests
simulate failures, their trash directories are kept around.
Fix it by explicitly setting TEST_OUTPUT_DIRECTORY appropriately for
sub-tests.
An alternative fix would be to pass the --root parameter that only
specifies where to put the trash directories, which would also work.
However, using TEST_OUTPUT_DIRECTORY is more futureproof in case
tests want to write more output in addition to the test-results/
(which are already suppressed in sub-tests using the HARNESS_ACTIVE
setting) and trash directories.
This fixes a regression introduced by 38b074d (t/test-lib.sh: fix
TRASH_DIRECTORY handling, 2013-04-14). Before that commit, the
TEST_OUTPUT_DIRECTORY setting was not respected consistently so most
tests did their work in a "trash" subdirectory of the current
directory instead of the output dir.

As suggested by Jeff King, this takes care to wrap the entire

You can set and test a prerequisite like this:
test_set_prereq FOO
test_have_prereq FOO && echo yes
You can negate the test in the shell like this:
! test_have_prereq && echo no
However, when you are using the automatic prerequisite
checking in test_expect_*, there is no opportunity to use
the shell negation. This patch introduces the syntax "!FOO"
to indicate that the test should only run if a prerequisite
is not meant.
One alternative is to set an explicit negative prerequisite,
like:
if system_has_foo; then
test_set_prereq FOO
else
test_set_prereq NO_FOO
fi
However, this doesn't work for lazy prerequisites, which
associate a single test with a single name. We could teach
the lazy prereq evaluator to set both forms, but the code
change ends up quite similar to this one (because we still
need to convert NO_FOO into FOO to find the correct lazy
script).

as well. Bot don't do that in case the resulting lines would be too
long. Also when there is no $variable_substitution in the body of a
here document, quote \EOF.
- Don't redirect the output of commands to /dev/null unconditionally,
the git testing framework should already take care of handling test
verbosity transparently and uniformly.

Rename the make_*_path functions so it's clearer what they do, in
particlar make clear what the differnce between make_absolute_path and
make_nonrelative_path is by renaming them real_path and absolute_path
respectively. make_relative_path has an understandable name and is
renamed to relative_path to maintain the name convention.
The function calls have been replaced 1-to-1 in their usage.

t0000 contains two snippets of actual test output. This causes
problems when passing -v to the test[*]: the test infrastructure
echoes the tests before running them, and the TAP parser then sees
this test output and concludes that two tests failed and that the TAP
output was badly formatted.
Guard against this by quoting the output in the source.
[*] either by running 'make smoke' with GIT_TEST_OPTS=-v, or with
prove ./t0000-basic.sh :: -v

Change test_expect_code to be a normal test command instead of a
top-level command.
As a top-level command it would fail in cases like:
test_expect_code 1 'phoney' '
foo && bar && (exit 1)
'
Here the test might incorrectly succeed if "foo" or "bar" happened to
fail with exit status 1. Instead we now do:
test_expect_success 'phoney' '
foo && bar && test_expect_code 1 "(exit 1)"
'
Which will only succeed if "foo" and "bar" return status 0, and "(exit
1)" returns status 1. Note that test_expect_code has been made slightly
noisier, as it reports the exit code it receives even upon success.
Some test code in t0000-basic.sh relied on the old semantics of
test_expect_code to test the test_when_finished command. I've
converted that code to use an external test similar to the TODO test I
added in v1.7.3-rc0~2^2~3.

Change the passing TODO test in t0000-basic.sh to run inside its own
test-lib.sh. The motivation is to have nothing out of the ordinary on
a normal test run for test smoking purposes.
If every normal test run has a passing TODO you're more likely to turn
a blind eye to it and not to investigate cases where things really are
passing unexpectedly.
It also makes the prove(1) output less noisy. Before:
All tests successful.

The support for multiple test prerequisites added by me in "test-lib:
Add support for multiple test prerequisites" was broken.
The for iterated over each prerequisite and returned true/false within
a case statement, but since it missed a return statement only the last
prerequisite in the list of prerequisites was ever considered, the
rest were ignored.
Fix that by changing the test_have_prereq code to something less
clever that keeps a count of the total prereqs and the ones we have
and compares the count at the end.
This comes with the added advantage that it's easy to list the missing
prerequisites in the test output, implement that while I'm at it.

Change the test_have_prereq function in test-lib.sh to support a
comma-separated list of prerequisites. This is useful for tests that
need e.g. both POSIXPERM and SANITY.
The implementation was stolen from Junio C Hamano and Johannes Sixt,
the tests and documentation were not. See the "Tests in Cygwin" thread
in May 2009 for the originals:

In tests, call test_cmp rather than raw diff where possible (i.e. if
the output does not go to a pipe), to allow the use of, say, 'cmp'
when the default 'diff -u' is not compatible with a vendor diff.
When that is not possible, use $DIFF, as set in GIT-BUILD-OPTIONS.

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.

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
$ GIT_SKIP_TESTS='t0001.1[34] t0010 t1301 t403[34] t4129.[47] t5701.7
t7701.3 t9100 t9101.26 t9119 t9124.[67] t9200.10 t9600.6' \
make test
(These additionally skipped tests depend on POSIX permissions that FAT on
Linux does not provide.)
