Many git commands that deal with working tree files try to remove a
directory that becomes empty (i.e. "git switch" from a branch that
has the directory to another branch that does not would attempt
remove all files in the directory and the directory itself). This

And like it, it has options to customize the various colored parts.
This patch updates the default git-grep colors to make them match the

It was possible to get the same result by setting the various `color.grep.<slot>`
options, but this patch makes `git grep --color` share the same color scheme as
`grep --color` by default without any user configuration.

In commit bee8691f19 ("stash: restore untracked files AFTER restoring
tracked files", 2021-09-10), we correctly identified that we should
restore changes to tracked files before attempting to restore untracked
files, and accordingly moved the code for restoring untracked files a
few lines down in do_apply_stash(). Unfortunately, the intervening
lines had some early return statements meaning that we suddenly stopped
restoring untracked files in some cases.
Even before the previous commit, there was another possible issue with
the current code -- a post-stash-apply 'git status' that was intended
to be run after restoring the stash was skipped when we hit a conflict
(or other error condition), which seems slightly inconsistent.
Fix both issues by saving the return status, and letting other
functionality run before returning.

315a84f9aa (subtree: use commits before rejoins for splits, 2018-09-28)
changed the signature of check_parents from 'check_parents [REV...]'
to 'check_parents PARENTS_EXPR INDENT'. In other words the variable list
of parent revisions became a list embedded in a string. However it
neglected to unpack the list again before sending it to cache_miss,
leading to incorrect calls whenever more than one parent was present.
This is the case whenever a merge commit is processed, with the end
result being a loss of performance from unecessary rechecks.
The indent parameter was subsequently removed in e9525a8a02 (subtree:

handling bug remained.
For consistency, take multiple arguments in check_parents,

When in cone mode sparse-checkout, it is unclear how 'git
sparse-checkout add <dir1> ...' should behave if the existing
sparse-checkout file does not match the cone mode patterns. Change the
behavior to fail with an error message about the existing patterns.
Also, all cone mode patterns start with a '/' character, so add that
restriction. This is necessary for our example test 'cone mode: warn on
bad pattern', but also requires modifying the example sparse-checkout
file we use to test the warnings related to recognizing cone mode
patterns.
This error checking would cause a failure further down the test script
because of a test that adds non-cone mode patterns without cleaning them
up. Perform that cleanup as part of the test now.

Add a test to t1091-sparse-checkout-builtin.sh that would result in an
infinite loop and out-of-memory error before this change. The issue
relies on having non-cone-mode patterns while trying to modify the
patterns in cone-mode.
The fix is simple, allowing us to break from the loop when the input
path does not contain a slash, as the "dir" pattern we added does not.
This is only a fix to the critical out-of-memory error. A better
response to such a strange state will follow in a later change.

Then core.sparseCheckoutCone is enabled, the sparse-checkout patterns are
used to populate two hashsets that accelerate pattern matching. If the user
modifies the sparse-checkout file outside of the 'sparse-checkout' builtin,
then strange patterns can happen, triggering some error checks.
One of these error checks is possible to hit when some special characters
exist in a line. A warning message is correctly written to stderr, but then
there is additional logic that attempts to remove the line from the hashset
and free the data. This leads to a segfault in the 'git sparse-checkout
list' command because it iterates over the contents of the hashset, which is
now invalid.
The fix here is to stop trying to remove from the hashset. In addition,
we disable cone mode sparse-checkout because of the malformed data. This
results in the pattern-matching working with a possibly-slower
algorithm, but using the patterns as they are in the sparse-checkout
file.
This also changes the behavior of commands such as 'git sparse-checkout
list' because the output patterns will be the contents of the
sparse-checkout file instead of the list of directories. This is an
existing behavior for other types of bad patterns.
Add a test that triggers the segfault without the code change.

We encourage identifying what, among many topics on `next`, exact
topics a new work depends on, instead of building directly on
`next`. Let's clarify this in the documentation.
Developers should know what they are building on top of, and be
aware of which part of the system is currently being worked on.
Encouraging them to make trial merges to `next` and `seen`
themselves will incentivize them to read others' changes and
understand them, eventually helping the developers to coordinate
among themselves and reviewing each others' changes.

file is involved in a rename/delete conflict BUT the file is unmodified
(either before or after renormalization), merge-ort was running into an
assertion failure. Prior to that commit (or if assertions were compiled
out), merge-ort would mis-merge instead, ignoring the rename/delete
conflict and just deleting the file.
Remove the assertions, fix the code appropriately, leave some good

The environment variable $SHELL is usually set to the user's
interactive shell. Our build and test scripts never use $SHELL because
there are no guarantees about its input language. Instead, we use
/bin/sh which should be a POSIX shell.
For systems with a broken /bin/sh, we allow to override that path via
SHELL_PATH. To run tests in yet another shell we allow to override
SHELL_PATH with TEST_SHELL_PATH.
Perf tests run in $SHELL via a wrapper defined in t/perf/perf-lib.sh,
so they break with e.g. SHELL=python. Use TEST_SHELL_PATH like
in other tests. TEST_SHELL_PATH is always defined because
t/perf/perf-lib.sh includes t/test-lib.sh, which includes
