6cd80496e9 ("gitk: Resize panes correctly when reducing window size",
2020-10-03) introduces a mechanism to record previously-set sash
positions to make sure that correct values are used while computing
resize proportions. However, if we are not using ttk, then sash
represents only the x coordinate and the recorded sash (`oldsash`) only
includes the x coordinate. When we need to access the y coordinate via
the recorded sash position, we generate the following Application Error
popup:
Error: expected integer but got ""
expected integer but got ""
expected integer but got ""
while executing
"$win sash place 0 $sash0 [lindex $s0 1]"
(procedure "resizeclistpanes" line 38)
invoked from within
"resizeclistpanes .tf.histframe.pwclist 2818"
(command bound to event)
To fix this, if we are not using ttk, we append the sash positions with
the y coordinates before recording them to match the use_ttk case.

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.

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
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

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.

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.

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.

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.

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.
