Lénaïc Huard b83f99c399 grep: align default colors with GNU grep ones
git-grep shares a lot of options with the standard grep tool.
Like GNU grep, it has coloring options to highlight the matching text.
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
GNU grep default ones [1].

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.

Elijah Newren 71cade5a0b stash: do not return before restoring untracked files
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.

James Limbouris 3ce8888fb4 subtree: fix argument handling in check_parents
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:
have $indent actually affect indentation, 2021-04-27), but the argument
handling bug remained.

For consistency, take multiple arguments in check_parents,
and pass all of them to cache_miss separately.

Derrick Stolee a3eca58445 sparse-checkout: refuse to add to bad patterns
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.

Derrick Stolee 391c3a1020 sparse-checkout: fix OOM error with mixed patterns
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.

Derrick Stolee a481d4378c sparse-checkout: fix segfault on malformed patterns
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.

Junio C Hamano fdfae830f8 SubmittingPatchs: clarify choice of base and testing
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.

Elijah Newren d30126c20d merge-ort: fix bug with renormalization and rename/delete conflicts
Ever since commit a492d5331c ("merge-ort: ensure we consult df_conflict
and path_conflicts", 2021-06-30), when renormalization is active AND a
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
comments in the code, and add a testcase for this situation.

Ævar Arnfjörð Bjarmason 2f12b31b74 Makefile: don't invoke msgfmt with --statistics
Remove the --statistics flag that I added in 5e9637c629 (i18n: add
infrastructure for translating Git with gettext, 2011-11-18). Our
Makefile output is good about reducing verbosity by default, except in
this case:

    $ rm -rf po/build/locale/e*; time make -j $(nproc) all
        SUBDIR templates
        MKDIR -p po/build/locale/el/LC_MESSAGES
        MSGFMT po/build/locale/el/LC_MESSAGES/git.mo
        MKDIR -p po/build/locale/es/LC_MESSAGES
        MSGFMT po/build/locale/es/LC_MESSAGES/git.mo
    1038 translated messages, 3325 untranslated messages.
    5230 translated messages.

I didn't have any good reason for using --statistics at the time other
than ad-hoc eyeballing of the output. We don't need to spew out
exactly how many messages we've got translated every time. Now we'll
instead emit:

    $ rm -rf po/build/locale/e*; time make -j $(nproc) all

Johannes Altmanninger 9ccab75608 t/perf: do not run tests in user's $SHELL
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
GIT-BUILD-OPTIONS.

can have an arbitrary size, so the format allows for arbitrarily sized reflog

This triggers a failure for reftable in t7006-pager.sh.

Ævar Arnfjörð Bjarmason fcd2c3d9d8 reflog + refs-backend: move "verbose" out of the backend
Move the handling of the "verbose" flag entirely out of
"refs/files-backend.c" and into "builtin/reflog.c". This allows the
backend to stop knowing about the EXPIRE_REFLOGS_VERBOSE flag.

The expire_reflog_ent() function shouldn't need to deal with the
implementation detail of whether or not we're emitting verbose output,
by doing this the --verbose output becomes backend-agnostic, so
reftable will get the same output.

I think the output is rather bad currently, and should e.g. be
implemented with some better future mode of progress.[ch], but that's
a topic for another improvement.

In the initial implementation of "git reflog" in 4264dc15e1 (git
reflog expire, 2006-12-19) we had this
lookup_commit_reference_gently().

I don't think we've ever found tags that we need to recursively
dereference in reflogs, so this should at least be changed to a
"lookup commit" as I'm doing here, although I can't think of a way
where it mattered in practice.

I also think we'd probably like to just die here if we have a NULL
object, but as this code needs to handle potentially broken
repositories let's just show an "error" but continue, the non-quiet
lookup_commit() will do for us. None of our tests cover the case where
"commit" is NULL after this lookup.

Ævar Arnfjörð Bjarmason 20d6b6868c reflog expire: use "switch" over enum values
Change code added in 03cb91b18c (reflog --expire-unreachable: special
case entries in "HEAD" reflog, 2010-04-09) to use a "switch" statement
with an exhaustive list of "case" statements instead of doing numeric
comparisons against the enum labels.

Now we won't assume that "x != UE_ALWAYS" means "(x == UE_HEAD || x ||
UE_NORMAL)". That assumption is true now, but we'd introduce subtle
bugs here if that were to change, now the compiler will notice and
error out on such errors.

Ævar Arnfjörð Bjarmason f2919bae98 reflog: change one->many worktree->refnames to use a string_list
Change the FLEX_ARRAY pattern added in bda3a31cc7 (reflog-expire:
Avoid creating new files in a directory inside readdir(3) loop,
2008-01-25) the string-list API instead.

This does not change any behavior, allows us to delete much of this
code as it's replaced by things we get from the string-list API for
free, as a result we need just one struct to keep track of this data,
instead of two.

The "DUP" -> "string_list_append_nodup(..., strbuf_detach(...))"
pattern here is the same as that used in a recent memory leak fix in
b202e51b15 (grep: fix a "path_list" memory leak, 2021-10-22).

Ævar Arnfjörð Bjarmason 46fbe418b2 reflog expire: narrow scope of "cb" in cmd_reflog_expire()
As with the preceding change for "reflog delete", change the "cb_data"
we pass to callbacks to be &cb.cmd itself, instead of passing &cb and
having the callback lookup cb->cmd.

This makes it clear that the "cb" itself is the same memzero'd
structure on each iteration of the for-loops that use &cb, except for
the "cmd" member.

The "struct expire_reflog_policy_cb" we pass to reflog_expire() will
have the members that aren't "cmd" modified by the callbacks, but
before we invoke them everything except "cmd" is zero'd out.

This included the "tip_commit", "mark_list" and "tips". It might have
looked as though we were re-using those between iterations, but the
first thing we did in reflog_expiry_prepare() was to either NULL them,
or clobber them with another value.

Joel Holdsworth 0fe3df45f2 git-p4: remove "rollback" verb
The "rollback" verb implements a simple algorithm which takes the set of
remote perforce tracker branches, or optionally, the complete collection
of local branches in a git repository, and deletes commits from these
branches until there are no commits left with a perforce change number
greater than than a user-specified change number. If the base of a git
branch has a newer change number than the user-specified maximum, then
the branch is deleted.

In future, there might be an argument for the addition of some kind of
"reset this branch back to a given perforce change number" verb for
git-p4. However, in its current form it is unlikely to be useful to
users for the following reasons:

  * The verb is completely undocumented. The only description provided
    contains the following text: "A tool to debug the multi-branch
    import. Don't use :)".

  * The verb has a very narrow purpose in that it applies the rollback
    operation to fixed sets of branches - either all remote p4 branches,
    or all local branches. There is no way for users to specify branches
    with more granularity, for example, allowing users to specify a
    single branch or a set of branches. The utility of the current
    implementation is therefore a niche within a niche.

Given these shortcomings, this patch removes the verb from git-p4.

Joel Holdsworth fb8dfc1ccb git-p4: remove "debug" verb
The git-p4 "debug" verb is described as "A tool to debug the output of
p4 -G".

The verb is not documented in any detail, but implements a function
which executes an arbitrary p4 command with the -G flag, which causes
perforce to format all output as marshalled Python dictionary objects.

The verb was implemented early in the history of git-p4, and may once
have served a useful purpose to the authors in the early stages of
development. However, the "debug" verb is no longer being used by the
current developers (and users) of git-p4, and whatever purpose the verb
previously offered is easily replaced by invoking p4 directly.

This patch therefore removes the verb from git-p4.

Han-Wen Nienhuys be49349c72 t7004: create separate tags for different tests
Reftable intentionally keeps reflog data for deleted refs.

This breaks tests that delete and recreate "refs/tags/tag_with_reflog" as traces
of the deletion are left in reflog. To resolve this, use a differently named ref
for each test case.
