08bdd3a185 cocci: drop bogus xstrdup_or_null() rule
13092a91 (cocci: refactor common patterns to use xstrdup_or_null(),
2016-10-12) introduced a rule to rewrite this conditional call to
xstrdup(E) and an assignment to variable V:

    - if (E)
    -    V = xstrdup(E);

into an unconditional call to xstrdup_or_null(E) and an assignment
to variable V:

    + V = xstrdup_or_null(E);

which is utterly bogus.  The original code may already have an
acceptable value in V and the conditional assignment may be to
improve the value already in V with a copy of a better value E when
(and only when) E is not NULL.

The rewritten construct unconditionally discards the existing value
of V and replaces it with a copy of E, even when E is NULL, which
changes the meaning of the program.

By the way, if it were

	-if (E && !V)
	-	V = xstrdup(E);
	+V = xstrdup_or_null(E);

it would probably have been correct.  But there is no existing code
that would have been improved by such a rule, so let's just remove
the bogus one without replacing with the more specific one.

6dfadc8981 clone: plug a miniscule leak
The remote_name variable is first assigned a copy of the value of
the "clone.defaultremotename" configuration variable and then by the
value of the "--origin" command line option.  The former is prepared
to see multiple instances of the configuration variable by freeing
the current value of the variable before a copy of the newly
discovered value gets assigned to it.  The latter however blindly
assigned a copy of the new value to the variable, thereby leaking
the value read from the configuration variable.

git format-patch only sets no_free when --output is given, causing it to
forget pathspecs after the first commit.  Set no_free unconditionally
instead.

The existing test was unable to detect this breakage because it checks

multiple files and a pathspec limiting the diff.  Replace it with a more

5cdb38458e 2.36 show regression fix
This only surfaced as a regression after 2.36 release, but the
breakage was already there with us for at least a year.

e900d494 (diff: add an API for deferred freeing, 2021-02-11)
introduced a mechanism to delay freeing resources held in
diff_options struct that need to be kept as long as the struct will
be reused to compute diff.  "git log -p" was taught to utilize the
mechanism but it was done with an incorrect assumption that the
underlying helper function, cmd_log_walk(), is called only once,
and it is OK to do the freeing at the end of it.

Alas, for "git show A B", the function is called once for each
commit given, so it is not OK to free the resources until we finish
calling it for all the commits given from the command line.

During 2.36 release cycle, we started clearing the <pathspec> as
part of this freeing, which made the bug a lot more visible.

Fix this breakage by tweaking how cmd_log_walk() frees the resources
at the end and using a variant of it that does not immediately free
the resources to show each commit object from the command line in
"git show".

Protect the fix with a few new tests.

f62563988f t0033-safe-directory: check the error message without matching the trash dir
Since 8959555cee (setup_git_directory(): add an owner check for the
top-level directory, 2022-03-02) when git finds itself in a repository
owned by someone else, it aborts with a "fatal: unsafe repository
(<repo path>)" error message and an advice about how to set the
'safe.directory' config variable to mark that repository as safe.
't0033-safe-directory.sh' contains tests that check that this feature
and handling said config work as intended.  To ensure that git dies
for the right reason, several of those tests check that its standard
error contains the name of that config variable, but:

  - it only appears in the advice part, not in the actual error
    message.

  - it is interpreted as a regexp by 'grep', so, because of the dot,
    it matches the name of the test script and the path of the trash
    directory as well.  Consequently, these tests could be fooled by
    any error message that would happen to include the path of the
    test repository.

Tighten these checks to look for "unsafe repository" instead.

124b05b230 rev-parse: integrate with sparse index
It is not obvious that the 'git rev-parse' builtin would use the sparse
index, but it is possible to parse paths out of the index using the
":<path>" syntax. The 'git rev-parse' output is only the OID of the
object found at that location, but otherwise behaves similarly to 'git
show :<path>'. This includes the failure conditions on directories and
the error messages depending on whether a path is in the worktree or
not.

The only code change required is to change the
command_requires_full_index setting in builtin/rev-parse.c, and we can
re-use many existing 'git show' tests for the rev-parse case.

4925adb4da object-name: diagnose trees in index properly
When running 'git show :<path>' where '<path>' is a directory, then
there is a subtle difference between a full checkout and a sparse
checkout. The error message from diagnose_invalid_index_path() reports
whether the path is on disk or not. The full checkout will have the
directory on disk, but the path will not be in the index. The sparse
checkout could have the directory not exist, specifically when that
directory is outside of the sparse-checkout cone.

In the case of a sparse index, we have yet another state: the path can
be a sparse directory in the index. In this case, the error message from
diagnose_invalid_index_path() would erroneously say "path '<path>' is in
the index, but not at stage 0", which is false.

Add special casing around sparse directory entries so we get to the
correct error message. This requires two checks in order to get parity
with the normal sparse-checkout case.

561287d342 object-name: reject trees found in the index
The get_oid_with_context_1() method is used when parsing revision
arguments. One particular case is to take a ":<path>" string and search
the index for the given path.

In the case of a sparse index, this might find a sparse directory entry,
in which case the contained object is a tree. In the case of a full
index, this search within the index would fail.

In order to maintain identical return state as in a full index, inspect
the discovered cache entry to see if it is a sparse directory and reject
it. This requires being careful around the only_to_die option to be sure
we die only at the correct time.

This changes the behavior of 'git show :<sparse-dir>', but does not
bring it entirely into alignment with a full index case. It specifically
hits the wrong error message within diagnose_invalid_index_path(). That
error message will be corrected in a future change.

a37d14422a show: integrate with the sparse index
The 'git show' command can take an input to request the state of an
object in the index. This can lead to parsing the index in order to load
a specific file entry. Without the change presented here, a sparse index
would expand to a full one, taking much longer than usual to access a
simple file.

There is one behavioral change that happens here, though: we now can
find a sparse directory entry within the index! Commands that previously
failed because we could not find an entry in the worktree or index now
succeed because we _do_ find an entry in the index.

There might be more work to do to make other situations succeed when
looking for an indexed tree, perhaps by looking at or updating the
cache-tree extension as needed. These situations include having a full
index or asking for a directory that is within the sparse-checkout cone
(and hence is not a sparse directory entry in the index).

For now, we demonstrate how the sparse index integration is extremely
simple for files outside of the cone as well as directories within the
cone. A later change will resolve this behavior around sparse
directories.

4f1ccef87c submodule--helper: fix initialization of warn_if_uninitialized
The .warn_if_uninitialized member was introduced by 48308681
(git submodule update: have a dedicated helper for cloning,
2016-02-29) to submodule_update_clone struct and initialized to
false.  When c9911c93 (submodule--helper: teach update_data more
options, 2022-03-15) moved it to update_data struct, it started
to initialize it to true but this change was not explained in
its log message.

The member is set to true only when pathspec was given, and is
used when a submodule that matched the pathspec is found
uninitialized to give diagnostic message.  "submodule update"
without pathspec is supposed to iterate over all submodules
(i.e. without pathspec limitation) and update only the
initialized submodules, and finding uninitialized submodules
during the iteration is a totally expected and normal thing that
should not be warned.

f8781bfda3 2.36 gitk/diff-tree --stdin regression fix
This only surfaced as a regression after 2.36 release, but the
breakage was already there with us for at least a year.

The diff_free() call is to be used after we completely finished with
a diffopt structure.  After "git diff A B" finishes producing
output, calling it before process exit is fine.  But there are
commands that prepares diff_options struct once, compares two sets
of paths, releases resources that were used to do the comparison,
then reuses the same diff_option struct to go on to compare the next
two sets of paths, like "git log -p".

After "git log -p" finishes showing a single commit, calling it
before it goes on to the next commit is NOT fine.  There is a
mechanism, the .no_free member in diff_options struct, to help "git
log" to avoid calling diff_free() after showing each commit and
instead call it just one.  When the mechanism was introduced in
e900d494 (diff: add an API for deferred freeing, 2021-02-11),
however, we forgot to do the same to "diff-tree --stdin", which *is*
a moral equivalent to "git log".

During 2.36 release cycle, we started clearing the pathspec in
diff_free(), so programs like gitk that runs

    git diff-tree --stdin -- <pathspec>

downstream of a pipe, processing one commit after another, started
showing irrelevant comparison outside the given <pathspec> from the
second commit.  The same commit, by forgetting to teach the .no_free
mechanism, broke "diff-tree --stdin -I<regexp>" and nobody noticed
it for over a year, presumably because it is so seldom used an
option.

But <pathspec> is a different story.  The breakage was very
prominently visible and was reported immediately after 2.36 was
released.

Fix this breakage by mimicking how "git log" utilizes the .no_free
member so that "diff-tree --stdin" behaves more similarly to "log".

Protect the fix with a few new tests.

11f9e8de3d cache: use const char * for get_object_directory()
The get_object_directory() method returns the exact string stored at
the_repository->objects->odb->path. The return type of "char *" implies
that the caller must keep track of the buffer and free() it when
complete. This causes significant problems later when the ODB is
accessed.

Use "const char *" as the return type to avoid this confusion. There are
no current callers that care about the non-const definition.

b56166ca57 multi-pack-index: use --object-dir real path
The --object-dir argument to 'git multi-pack-index' allows a user to
specify an alternate to use instead of the local $GITDIR. This is used
by third-party tools like VFS for Git to maintain the pack-files in a
"shared object cache" used by multiple clones.

On Windows, the user can specify a path using a Windows-style file path
with backslashes such as "C:\Path\To\ObjectDir". This same path style is
used in the .git/objects/info/alternates file, so it already matches the
path of that alternate. However, find_odb() converts these paths to
real-paths for the comparison, which use forward slashes. As of the
previous change, lookup_multi_pack_index() uses real-paths, so it
correctly finds the target multi-pack-index when given these paths.

Some commands such as 'git multi-pack-index repack' call child processes
using the object_dir value, so it can be helpful to convert the path to
the real-path before sending it to those locations.

Add a callback to convert the real path immediately upon parsing the
argument. We need to be careful that we don't store the exact value out
of get_object_directory() and free it, or we could corrupt a later use
of the_repository->objects->odb->path.

We don't use get_object_directory() for the initial instantiation in
cmd_multi_pack_index() because we need 'git multi-pack-index -h' to work
without a Git repository.

eafcc6de52 midx: use real paths in lookup_multi_pack_index()
This helper looks for a parsed multi-pack-index whose object directory
matches the given object_dir. Before going into the loop over the parsed
multi-pack-indexes, it calls find_odb() to ensure that the given
object_dir is actually a known object directory.

However, find_odb() uses real-path manipulations to compare the input to
the alternate directories. This same real-path comparison is not used in
the loop, leading to potential issues with the strcmp().

Update the method to use the real-path values instead.

d097a23bfa clone: die() instead of BUG() on bad refs
When cloning directly from a local repository, we load a list of refs
based on scanning the $GIT_DIR/refs/ directory of the "server"
repository. If files exist in that directory that do not parse as
hexadecimal hashes, then the ref array used by write_remote_refs()
ends up with some entries with null OIDs. This causes us to hit a BUG()
statement in ref_transaction_create():

  BUG: create called without valid new_oid

This BUG() call used to be a die() until 033abf97f (Replace all
die("BUG: ...") calls by BUG() ones, 2018-05-02). Before that, the die()
was added by f04c5b552 (ref_transaction_create(): check that new_sha1 is
valid, 2015-02-17).

The original report for this bug [1] mentioned that this problem did not
exist in Git 2.27.0. The failure bisects unsurprisingly to 968f12fda
(refs: turn on GIT_REF_PARANOIA by default, 2021-09-24). When
GIT_REF_PARANOIA is enabled, this case always fails as far back as I am
able to successfully compile and test the Git codebase.

[1] https://github.com/git-for-windows/git/issues/3781

There are two approaches to consider here. One would be to remove this
BUG() statement in favor of returning with an error. There are only two
callers to ref_transaction_create(), so this would have a limited
impact.

The other approach would be to add special casing in 'git clone' to
avoid this faulty input to the method.

While I originally started with changing 'git clone', I decided that
modifying ref_transaction_create() was a more complete solution. This
prevents failing with a BUG() statement when we already have a good way
to report an error (including a reason for that error) within the
method. Both callers properly check the return value and die() with the
error message, so this is an appropriate direction.

The added test helps check against a regression, but does check that our
intended error message is handled correctly.

45a14f578e Revert "name-rev: release unused name strings"
This reverts commit 2d53975488.

3656f84278 (name-rev: prefer shorter names over following merges,
2021-12-04) broke the assumption of 2d53975488 (name-rev: release unused
name strings, 2020-02-04) that a better name for a child is a better
name for all of its ancestors as well, because it added a penalty for
generation > 0.  This leads to strings being free(3)'d that are still
needed.

079f970971 (name-rev: sort tip names before applying, 2020-02-05)
already reduced the number of free(3) calls for the use case that
motivated the original patch (name-rev --all in the Chromium repository)
from ca. 44000 to 5, and 3656f84278 eliminated even those few.  So this
revert won't affect name-rev's performance on that particular repo.

96697781e0 log: "--since-as-filter" option is a non-terminating "--since" variant
The "--since=<time>" option of "git log" limits the commits displayed by
the command by stopping the traversal once it sees a commit whose
timestamp is older than the given time and not digging further into its
parents.

This is OK in a history where a commit always has a newer timestamp than
any of its parents'.  Once you see a commit older than the given <time>,
all ancestor commits of it are even older than the time anyway.  It
poses, however, a problem when there is a commit with a wrong timestamp
that makes it appear older than its parents.  Stopping traversal at the
"incorrectly old" commit will hide its ancestors that are newer than
that wrong commit and are newer than the cut-off time given with the
--since option.  --max-age and --after being the synonyms to --since,
they share the same issue.

Add a new "--since-as-filter" option that is a variant of
"--since=<time>".  Instead of stopping the traversal to hide an old
enough commit and its all ancestors, exclude commits with an old
timestamp from the output but still keep digging the history.

Without other traversal stopping options, this will force the command in
"git log" family to dig down the history to the root.  It may be an
acceptable cost for a small project with short history and many commits
with screwy timestamps.

It is quite unlikely for us to add traversal stopper other than since,
so have this as a --since-as-filter option, rather than a separate
--as-filter, that would be probably more confusing.

3506cae04f CI: select CC based on CC_PACKAGE (again)
Fix a regression in 707d2f2fe8 (CI: use "$runs_on_pool", not
"$jobname" to select packages & config, 2021-11-23).

In that commit I changed CC=gcc from CC=gcc-9, but on OSX the "gcc" in
$PATH points to clang, we need to use gcc-9 instead. Likewise for the
linux-gcc job CC=gcc-8 was changed to the implicit CC=gcc, which would
select GCC 9.4.0 instead of GCC 8.4.0.

Furthermore in 25715419bf (CI: don't run "make test" twice in one
job, 2021-11-23) when the "linux-TEST-vars" job was split off from
"linux-gcc" the "cc_package: gcc-8" line was copied along with
it, so its "cc_package" line wasn't working as intended either.

As a table, this is what's changed by this commit, i.e. it only
affects the linux-gcc, linux-TEST-vars and osx-gcc jobs:

	|-------------------+-----------+-------------------+-------+-------|
	| jobname           | vector.cc | vector.cc_package | old   | new   |
	|-------------------+-----------+-------------------+-------+-------|
	| linux-clang       | clang     | -                 | clang | clang |
	| linux-sha256      | clang     | -                 | clang | clang |
	| linux-gcc         | gcc       | gcc-8             | gcc   | gcc-8 |
	| osx-clang         | clang     | -                 | clang | clang |
	| osx-gcc           | gcc       | gcc-9             | clang | gcc-9 |
	| linux-gcc-default | gcc       | -                 | gcc   | gcc   |
	| linux-TEST-vars   | gcc       | gcc-8             | gcc   | gcc-8 |

41c64ae0e7 show-branch: -g and --current are incompatible
When "--current" is given to "git show-branch" running in the
"--reflog" mode, the code tries to reference a "reflog" message
that does not even exist.  This is because the --current is not
prepared to work in that mode.

The reason "--current" exists is to support this request:

    I list branches on the command line.  These are the branchesI
    care about and I use as anchoring points. I may or may not be on
    one of these main branches.  Please make sure I can view the
    commits on the current branch with respect to what is in these
    other branches.

And to serve that request, the code checks if the current branch is
among the ones listed on the command line, and adds it only if it is
not to the end of one array, which essentially lists the objects.
The reflog mode additionally uses another array to list reflog
messages, which the "--current" code does not add to.  This leaves
one uninitialized slot at the end of the array of reflog messages,
and causes the program to show garbage or segfault.

Catch the unsupported (and meaningless) combination and exit with a
usage error.

There are other combinations of options that are incompatible but
have not been tested.  Add test to cover them while adding coverage
for this new combination.

9e5ebe9668 rebase: use correct base for --keep-base when a branch is given
--keep-base rebases onto the merge base of the given upstream and the
current HEAD regardless of whether a branch is given. This is contrary
to the documentation and to the option's intended purpose. Instead,
rebase onto the merge base of the given upstream and the given branch.

8af759374e diff: use mks_tempfile_dt()
Git uses temporary files to pass the contents of blobs to external diff
programs and textconv filters.  It calls mks_tempfile_ts() to create
them, which puts them all in the same directory.  This requires adding
a random name prefix.

Use mks_tempfile_dt() instead, which allows the files to have arbitrary
names, each in their own separate temporary directory.  This way they
can have the same basename as the original blob, which looks nicer in
graphical diff programs.

The test in t4020 to check the prettiness of the temporary paths was
neutered by 5476bdf0e8 (diff tests: don't ignore "git diff" exit code in
"read" loop, 2022-03-07), which removed its grep check without replacing
it with an equivalent test_cmp check.  Add one that only checks the
basename of the temporary file and nothing else.

And make the test more robust while at it, by using test_when_finished
to get rid of the added file even if the test fails.

2c2db194bd tempfile: add mks_tempfile_dt()
Add a function to create a temporary file with a certain name in a
temporary directory created using mkdtemp(3).  Its result is more
sightly than the paths created by mks_tempfile_ts(), which include
a random prefix.  That's useful for files passed to a program that
displays their name, e.g. an external diff tool.

c0befa0c03 commit-graph: close file before returning NULL
There are two reasons that we could return NULL early within
load_commit_graph_chain():

 1. The file does not exist, so the file pointer is NULL.
 2. The file exists, but is too small to contain a single hash.

These were grouped together when the function was first written in
5c84b3396 (commit-graph: load commit-graph chains, 2019-06-18) in order
to simplify how the 'chain_name' string is freed. However, the current
code leaves a narrow window where the file pointer is not closed when
the file exists, but is rejected for being too small.

Split out these cases separately to ensure we close the file in this
case.
