We have a custom match_pattern_list() function which we use for matching
test names (like "t1234") against glob-like patterns (like "t1???") for
$GIT_SKIP_TESTS, --verbose-only, etc.
Those patterns may have multiple whitespace-separated elements (e.g.,
"t0* t1234 t5?78"). The callers of match_pattern_list thus pass the
strings unquoted, so that the shell does the usual field-splitting into
separate arguments.
But this also means the shell will do the usual globbing for each
argument, which can result in us seeing an expansion based on what's in
the filesystem, rather than the real pattern. For example, if I have the
path "t5000" in the filesystem, and you feed the pattern "t?000", that
_should_ match the string "t0000", but it won't after the shell has
expanded it to "t5000".
This has been a bug ever since that function was introduced. But it
didn't usually trigger since we typically use the function inside the
trash directory, which has a very limited set of files that are unlikely
to match. It became a lot easier to trigger after edc23840b0 (test-lib:
bring $remove_trash out of retirement, 2021-05-10), because now we match
$GIT_SKIP_TESTS before even entering the trash directory. So the t5000
example above can be seen with:
GIT_SKIP_TESTS=t?000 ./t0000-basic.sh
which should skip all tests but doesn't.
We can fix this by using "set -f" to ask the shell not to glob (which is
in POSIX, so should hopefully be portable enough). We only want to do
this in a subshell (to avoid polluting the rest of the script), which
means we need to get the whole string intact into the match_pattern_list
function by quoting it. Arguably this is a good idea anyway, since it
makes it much more obvious that we intend to split, and it's not simply
sloppy scripting.

Git grep allows combining two patterns with --and. It checks and
reports if the second pattern is missing when compiling the expression.
A missing first pattern, however, is only reported later at match time.
Thus no error is returned if no matching is done, e.g. because no file
matches the also given pathspec.
When that happens we get an expression tree with an GREP_NODE_AND node
and a NULL pointer to the missing left child. free_pattern_expr()
tries to dereference it during the cleanup at the end, which results
in a segmentation fault.
Fix this by verifying the presence of the left operand at expression
compilation time.

Some tests will fail under --verbose because while we've unset COLUMNS
since b1d645b58ac (tests: unset COLUMNS inherited from environment,
2012-03-27), we also look for the columns with an ioctl(..,
TIOCGWINSZ, ...) on some platforms. By setting COLUMNS again we
preempt the TIOCGWINSZ lookup in pager.c's term_columns(), it'll take
COLUMNS over TIOCGWINSZ,
This fixes t0500-progress-display.sh., which broke because of a
combination of the this issue and the progress output reacting to the
column width since 545dc345ebd (progress: break too long progress bar
lines, 2019-04-12). The t5324-split-commit-graph.sh fails in a similar
manner due to progress output, see [1] for details.
The issue is not specific to progress.c, the diff code also checks
COLUMNS and some of its tests can be made to fail in a similar
manner[2], anything that invokes a pager is potentially affected.
See ea77e675e56 (Make "git help" react to window size correctly,
2005-12-18) and ad6c3739a33 (pager: find out the terminal width before
spawning the pager, 2012-02-12) for how the TIOCGWINSZ code ended up
in pager.c

Not all systems have a readlink program available for use by the shell.
This causes t3210 to fail on at least AIX. Let's provide a perl
one-liner to do the same thing, and use it there.
I also updated calls in t9802. Nobody reported failure there, but it's
the same issue. Presumably nobody actually tests with p4 on AIX in the
first place (if it is even available there).
I left the use of readlink in the "--valgrind" setup in test-lib.sh, as
valgrind isn't available on exotic platforms anyway (and I didn't want
to increase dependencies between test-lib.sh and test-lib-functions.sh).
There's one other curious case. Commit d2addc3b96 (t7800: readlink may
not be available, 2016-05-31) fixed a similar case. We can't use our
wrapper function there, though, as it's inside a sub-script triggered by
Git. It uses a slightly different technique ("ls" piped to "sed"). I
chose not to use that here as it gives confusing "ls -l" output if the
file is unexpectedly not a symlink (which is OK for its limited use, but
potentially confusing for general use within the test suite). The perl
version emits the empty string.

Before comparing with the expect file, we used to call function
"make_user_friendly_and_stable_output" to filter out trailing spaces in
output. Ævar recommends using pattern "s/Z$//" to prepare expect file,
and then compare it with raw output.
Since we have fixed the issue of occasionally missing the clear-to-eol
suffix when displaying sideband #2 messages, it is safe and stable to
test against raw output.

Start by creating an "actual" file in a core.hooksPath test that has
the hook echoing to the "actual" file.
We later test_cmp that file to see what hooks were run. If we fail to
run our hook(s) we'll have an empty list of hooks for the test_cmp
instead of a nonexisting file. For the logic of this test that makes more sense.
See 867ad08a261 (hooks: allow customizing where the hook directory is,

Since cd1d61c44f (make union merge an xdl merge favor, 2010-03-01), we
pass NULL to ll_xdl_merge() for the "name" labels of the ancestor, ours
and theirs buffers. We usually use these for annotating conflict markers
left in a file. For a union merge, these shouldn't matter; the point of
it is that we'd never leave conflict markers in the first place.
But there is one code path where we may dereference them: if the file
contents appear to be binary, ll_binary_merge() will give up and pass
them to warning() to generate a message for the user (that was true even
when cd1d61c44f was written, though the warning was in ll_xdl_merge()
back then).
That can result in a segfault, though on many systems (including glibc),
the printf routines will helpfully just say "(null)" instead. We can
extend our binary-union test in t6406 to check stderr, which catches the
problem on all systems.
This also fixes a warning from "gcc -O3". Unlike lower optimization
levels, it inlines enough to see that the NULL can make it to warning()
and complains:
In function ‘ll_binary_merge’,
inlined from ‘ll_xdl_merge’ at ll-merge.c:115:10,
inlined from ‘ll_union_merge’ at ll-merge.c:151:9:

Prior to commit a944af1d86 (merge: teach -Xours/-Xtheirs to binary
ll-merge driver, 2012-09-08), we always reported a conflict from
ll_binary_merge() by returning "1" (in the xdl_merge and ll_merge code,
this value is the number of conflict hunks). After that commit, we
report zero conflicts if the "variant" flag is set, under the assumption
that it is one of XDL_MERGE_FAVOR_OURS or XDL_MERGE_FAVOR_THEIRS.
But this gets confused by XDL_MERGE_FAVOR_UNION. We do not know how to
do a binary union merge, but erroneously report no conflicts anyway (and
just blindly use the "ours" content as the result).
Let's tighten our check to just the cases that a944af1d86 meant to
cover. This fixes the union case (which existed already back when that
commit was made), as well as future-proofing us against any other
variants that get added later.
Note that you can't trigger this from "git merge-file --union", as that
bails on binary files before even calling into the ll-merge machinery.
The test here uses the "union" merge attribute, which does erroneously
report a successful merge.

Change various cmd_* functions that claim to return an "int" to use
"return" instead of exit() to indicate an exit code. These were not
marked with NORETURN, and by directly exit()-ing we'll skip the
cleanup git.c would otherwise do (e.g. closing fd's, erroring if we
can't). See run_builtin() in git.c.
In the case of shell.c and sh-i18n--envsubst.c this was the result of
an incomplete migration to using a cmd_main() in 3f2e2297b9 (add an
extra level of indirection to main(), 2016-07-01).

In some test-cases, UTF-8 locale is required. To find such locale,
we're using the first available UTF-8 locale that returned by
"locale -a".
However, the locale(1) utility is unavailable on some systems,
e.g. Linux with musl libc.
However, without "locale -a", we can't guess provided UTF-8 locale.
Add a Makefile knob GIT_TEST_UTF8_LOCALE and activate it for
linux-musl in our CI system.
Rename t/lib-git-svn.sh:prepare_a_utf8_locale to prepare_utf8_locale,
since we no longer prepare the variable named "a_utf8_locale",
but set up a fallback value for GIT_TEST_UTF8_LOCALE instead.
The fallback will be LC_ALL, LANG environment variable,
or the first UTF-8 locale from output of "locale -a", in that order.

* rs/parallel-checkout-test-fix:
parallel-checkout: avoid dash local bug in tests
|
|
Dash bug https://bugs.launchpad.net/ubuntu/+source/dash/+bug/139097
lets the shell erroneously perform field splitting on the expansion of a
command substitution during declaration of a local variable. It causes
the parallel-checkout tests to fail e.g. when running them with
/bin/dash on MacOS 11.4, where they error out like this:
./t2080-parallel-checkout-basics.sh: 33: local: 0: bad variable name
That's because the output of wc -l contains leading spaces and the
returned number of lines is treated as another variable to declare, i.e.
as in "local workers= 0".
Work around it by enclosing the command substitution in quotes.

The --batch code to print an object assumes we found out the type of
the object from calling oid_object_info_extended(). This is true for
the default format, but even in a custom format, we manually modify
the object_info struct to ask for the type.
This assumption was broken by 845de33a5b (cat-file: avoid noop calls
to sha1_object_info_extended, 2016-05-18). That commit skips the call
to oid_object_info_extended() entirely when --batch-all-objects is in
use, and the custom format does not include any placeholders that
require calling it.
Or when the custom format only include placeholders like %(objectname) or
%(rest), oid_object_info_extended() will not get the type of the object.
This results in an error when we try to confirm that the type didn't
change:
$ git cat-file --batch=batman --batch-all-objects
batman
fatal: object 000023961a0c02d6e21dc51ea3484ff71abf1c74 changed type!?
and also has other subtle effects (e.g., we'd fail to stream a blob,
since we don't realize it's a blob in the first place).
We can fix this by flipping the order of the setup. The check for "do
we need to get the object info" must come _after_ we've decided
whether we need to look up the type.

to test the functionality of pack-refs itself, as that is covered by
t3210-pack-refs.sh.

The packed/loose ref storage is an overlay combination of packed-refs (refs and
tags in a single file) and one-file-per-ref. This creates all kinds of edge
cases related to directory/file conflicts, (non-)empty directories, and the
locking scheme, none of which applies to reftable.

In reftable, there is no notion of a per-ref 'existence' of a reflog. Each
reflog entry has its own key, so it is not possible to distinguish between
{reflog doesn't exist,reflog exists but is empty}. This makes the logic
in log_ref_setup() (file refs/files-backend.c), which depends on the existence
of the reflog file infeasible.
