Enable sparse index in 'git stash' by disabling
'command_requires_full_index'.
With sparse index enabled, some subcommands of 'stash' work without
expanding the index, e.g., 'git stash', 'git stash list', 'git stash drop',
etc. Others ensure the index is expanded either directly (as in the case of
'git stash [pop|apply]', where the call to 'merge_recursive_generic()' in
'do_apply_stash()' triggers the expansion), or in a command called
internally by stash (e.g., 'git update-index' in 'git stash -u'). So, in
addition to enabling sparse index, add tests to 't1092' demonstrating which
variants of 'git stash' expand the index, and which do not.
Finally, add the option to skip writing 'untracked.txt' in
'ensure_not_expanded', and use that option to successfully apply stashed
untracked files without a conflict in 'untracked.txt'.

Add tests verifying expected 'git stash' behavior in
't1092-sparse-checkout-compatibility'. These cases establish the expected
behavior of 'git stash' in a sparse-checkout and verify consistency both
with and without a sparse index. Although no sparse index compatibility has
been integrated into 'git stash' yet, the tests are all 'expect_success' -
we don't want the cone-mode sparse-checkout behavior to change depending on
whether it is using a sparse index or not. Therefore, we expect these tests
to continue passing once sparse index is integrated with 'git stash'.
Additionally, add performance test cases for 'git stash' both with and
without untracked files. Note that, unlike the other tests in
'p2000-sparse-operations.sh', the tests added for 'stash' are combination
operations. This is done to ensure the stash/unstash is not blocked by the
modification of '$SPARSE_CONE/a' performed as part of 'test_perf_on_all'.

This reverts commit 2a0cafd464709cfa22fe7249290c644a2a26c520,
as it expects a working "a ref deletion must produce a single

which we do not have.

With the addition of the safe.directory in 8959555ce
(setup_git_directory(): add an owner check for the top-level directory,
2022-03-02) released in v2.35.2, we are receiving feedback from a
variety of users about the feature.
Some users have a very large list of shared repositories and find it
cumbersome to add this config for every one of them.
In a more difficult case, certain workflows involve running Git commands
within containers. The container boundary prevents any global or system
config from communicating `safe.directory` values from the host into the
container. Further, the container almost always runs as a different user
than the owner of the directory in the host.
To simplify the reactions necessary for these users, extend the
definition of the safe.directory config value to include a possible '*'
value. This value implies that all directories are safe, providing a
single setting to opt-out of this protection.
Note that an empty assignment of safe.directory clears all previous
values, and this is already the case with the "if (!value || !*value)"
condition.

It seems that nothing is ever checking to make sure the safe directories
in the configs actually have the key safe.directory, so some unrelated
config that has a value with a certain directory would also make it a
safe directory.

It is difficult to change the ownership on a directory in our test
suite, so insert a new GIT_TEST_ASSUME_DIFFERENT_OWNER environment
variable to trick Git into thinking we are in a differently-owned
directory. This allows us to test that the config is parsed correctly.

Test regression fix.
* ld/sparse-index-bash-completion:
t9902: split test to run on appropriate systems
|
|
The "FUNNYNAMES" test prerequisite passes on Cygwin, as the Cygwin
file system interface has a workaround for the underlying operating
system's lack of support for tabs, newlines or quotes. However, it does
not add support for backslash, which is treated as a directory
separator, meaning one of the tests added by 48803821b1 ("completion:
handle unusual characters for sparse-checkout", 2022-02-07) will fail on
Cygwin.
To avoid this failure while still getting maximal test coverage, split
that test into two: test handling of paths that include tabs on anything
that has the FUNNYNAMES prerequisite, but skip testing handling of paths
that include backslashes unless both FUNNYNAMES is set and the system is
not Cygwin.
It might be nice to have more granularity than "FUNNYNAMES" and its
sibling "FUNNIERNAMES" provide, so that tests could be run based on
specific individual characters supported by the file system being
tested, but that seems like it would make the prerequisite checks in
this area much more verbose for very little gain.

The error "not tracking: ambiguous information for ref" is raised
when we are evaluating what tracking information to set on a branch,
and find that the ref to be added as tracking branch is mapped
under multiple remotes' fetch refspecs.
This can easily happen when a user copy-pastes a remote definition
in their git config, and forgets to change the tracking path.
Add advice in this situation, explicitly highlighting which remotes
are involved and suggesting how to correct the situation. Also
update a test to explicitly expect that advice.

"git branch --recurse-submodules" does not propagate "--track=inherit"
or "--no-track" to submodules, which causes submodule branches to use
the wrong tracking mode [1]. To fix this, pass the correct options to
the "submodule--helper create-branch" child process and test for it.
While we are refactoring the same code, replace "--track" with the
synonymous, but more consistent-looking "--track=direct" option
(introduced at the same time as "--track=inherit", d3115660b4 (branch:
add flags and config to inherit tracking, 2021-12-20)).
[1] This bug is partially a timing issue: "branch --recurse-submodules"
was introduced around the same time as "--track=inherit", and even
though I rebased "branch --recurse-submodules" on top of that, I had
neglected to support the new tracking mode. Omitting "--no-track"
was just a plain old mistake, though.

Update the stat info of the moved index entry in 'rename_index_entry_at()'
if the entry is up-to-date with the index. Internally, 'git mv' uses
'rename_index_entry_at()' to move the source index entry to the destination.
However, it directly copies the stat info of the original cache entry, which
will not reflect the 'ctime' of the file renaming operation that happened as
part of the move. If a file is otherwise up-to-date with the index, that
difference in 'ctime' will make the entry appear out-of-date until the next
index-refreshing operation (e.g., 'git status').
Some commands, such as 'git reset', use the cached stat information to
determine whether a file is up-to-date; if this information is incorrect,
the command will fail when it should pass. In order to ensure a moved entry
is evaluated as 'up-to-date' when appropriate, refresh the destination index
entry's stat info in 'git mv' if and only if the file is up-to-date.
Note that the test added in 't7001-mv.sh' requires a "sleep 1" to ensure the
'ctime' of the file creation will be definitively older than the 'ctime' of
the renamed file in 'git mv'.

NEEDSWORK: The Windows version of `utime()` (aka `mingw_utime()`) does

Do not copy any of the various fsmonitor--daemon files from the .git
directory of the (GIT_PREF_REPO or GIT_PERF_LARGE_REPO) source repo
into the test's trash directory.
When perf tests start, they copy the contents of the source repo into
the test's trash directory. If fsmonitor is running in the source repo,
there may be control files, such as the IPC socket and/or fsmonitor
cookie files. These should not be copied into the test repo.
Unix domain sockets cannot be copied in the manner used by the test
setup, so if present, the test setup fails.
Cookie files are harmless, but we should avoid them.
The builtin fsmonitor keeps all such control files/sockets in
.git/fsmonitor--daemon*, so it is simple to exclude them.

Add the "feature: fsmonitor--daemon" message to the output of
`git version --build-options`.
The builtin FSMonitor is only available on certain platforms and
even then only when certain Makefile flags are enabled, so print
a message in the verbose version output when it is available.
This can be used by test scripts for prereq testing. Granted, tests
could just try `git fsmonitor--daemon status` and look for a 128 exit
code or grep for a "not supported" message on stderr, but these
methods are rather obscure.
The main advantage is that the feature message will automatically
appear in bug reports and other support requests.
This concept was also used during the development of Scalar for
similar reasons.
