Junio C Hamano e0ad13977a fsck: do not dereference NULL while checking resolve-undo data
When we found an invalid object recorded in the resolve-undo data,
we would have ended up dereferencing NULL while fsck.  Reporting the
problem and going on to the next object is the right thing to do
here.

Noticed by SZEDER Gábor.

Junio C Hamano 5a5ea141e7 revision: mark blobs needed for resolve-undo as reachable
The resolve-undo extension was added to the index in cfc5789a
(resolve-undo: record resolved conflicts in a new index extension
section, 2009-12-25).  This extension records the blob object names
and their modes of conflicted paths when the path gets resolved
(e.g. with "git add"), to allow "undoing" the resolution with
"checkout -m path".  These blob objects should be guarded from
garbage-collection while we have the resolve-undo information in the
index (otherwise unresolve operation may try to use a blob object
that has already been pruned away).

But the code called from mark_reachable_objects() for the index
forgets to do so.  Teach add_index_objects_to_pending() helper to
also add objects referred to by the resolve-undo extension.

Also make matching changes to "fsck", which has code that is fairly
similar to the reachability stuff, but have parallel implementations
for all these stuff, which may (or may not) someday want to be unified.

Junio C Hamano 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 fast-export doesn't set no_free, so path limiting stopped working

only changes to the specified files are exported.

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
stderr for the absence of a certain string, but format-patch writes to
stdout.  Also the test was not checking the case of one commit modifying
multiple files and a pathspec limiting the diff.  Replace it with a more

Junio C Hamano 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.

Orgad Shaneh 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.

Junio C Hamano 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.

Derrick Stolee 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.

René Scharfe 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.

Junio C Hamano 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.

In 9c4d58ff2c (ls-tree: split up "fast path" callbacks, 2022-03-23), a

passed on the command line, regardless of whether or not we also pass
the `-r` (recursive) flag.

Fix this by making show_tree_long() return the value of `recurse`,
rather than always returning 1. This value is interpreted by
read_tree_at() to be a signal on whether or not to recurse.

Phillip Wood d97eb302ea worktree: add -z option for list subcommand
Add a -z option to be used in conjunction with --porcelain that gives
NUL-terminated output. As 'worktree list --porcelain' does not quote
worktree paths this enables it to handle worktree paths that contain
newlines.

Glen Choo 75388bf5b4 branch: support more tracking modes when recursing
"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.

SZEDER Gábor 840344db75 reflog: fix 'show' subcommand's argv
cmd_reflog() invokes parse_options() with PARSE_OPT_KEEP_ARGV0, but it
doesn't account for the retained argv[0] before invoking
cmd_reflog_show() to handle the 'git reflog show' subcommand.
Consequently, cmd_reflog_show() always gets an 'argv' array starting
with elements argv[0]="reflog" and argv[1]="show".

Strip the name of the git command from the 'argv' array before passing
it to the function handling the 'show' subcommand.

There is no user-visible bug here, because cmd_reflog_show() doesn't
have any options or parameters of its own.

Ævar Arnfjörð Bjarmason 5cb28270a1 pack-objects: lazily set up "struct rev_info", don't leak
In the preceding [1] (pack-objects: move revs out of
get_object_list(), 2022-03-22) the "repo_init_revisions()" was moved
to cmd_pack_objects() so that it unconditionally took place for all
invocations of "git pack-objects".

We'd thus start leaking memory, which is easily reproduced in
e.g. git.git by feeding e83c516331 (Initial revision of "git", the
information manager from hell, 2005-04-07) to "git pack-objects";

    $ echo e83c516331 | ./git pack-objects initial

	SUMMARY: LeakSanitizer: 7120 byte(s) leaked in 1 allocation(s).
	Aborted

Narrowly fixing that commit would have been easy, just add call
repo_init_revisions() right before get_object_list(), which is
effectively what was done before that commit.

But an unstated constraint when setting it up early is that it was
needed for the subsequent [2] (pack-objects: parse --filter directly
into revs.filter, 2022-03-22), i.e. we might have a --filter
command-line option, and need to either have the "struct rev_info"
setup when we encounter that option, or later.

Let's just change the control flow so that we'll instead set up the
"struct rev_info" only when we need it. Doing so leads to a bit more
verbosity, but it's a lot clearer what we're doing and why.

An earlier version of this commit[3] went behind
opt_parse_list_objects_filter()'s back by faking up a "struct option"
before calling it. Let's avoid that and instead create a blessed API
for this pattern.

We could furthermore combine the two get_object_list() invocations
here by having repo_init_revisions() invoked on &pfd.revs, but I think
clearly separating the two makes the flow clearer. Likewise
redundantly but explicitly (i.e. redundant v.s. a "{ 0 }") "0" to
"have_revs" early in cmd_pack_objects().

While we're at it add parentheses around the arguments to the OPT_*
macros in in list-objects-filter-options.h, as we need to change those
lines anyway. It doesn't matter in this case, but is good general
practice.
