The handling to die early when there is no EDITOR is valuable when
used in normal code (i.e., editor.c). In git-var, where
null/empty-string is a perfectly valid value to return, it doesn't
make as much sense.
Remove this handling from `git var GIT_EDITOR` so that it does not
fail so noisily when there is no defined editor.

Before, git-var could print usage() even if the command was invoked
correctly with a variable defined in git_vars -- provided that its
read() function returned NULL.
Now, we only print usage() only if it was called with a logical
variable that wasn't defined -- regardless of read().
Since we now know the variable is valid when we call read_var(), we
can avoid printing usage() here (and exiting with code 129) and
instead exit quietly with code 1. While exiting with a different code
can be a breaking change, it's far better than changing the exit
status more generally from 'failure' to 'success'.

Python is missing from the default ubuntu-22.04 runner image, which
prevents git-p4 from working. To install python on ubuntu, we need
to provide the correct package names:
* On Ubuntu 18.04 (bionic), "/usr/bin/python2" is provided by the
"python" package, and "/usr/bin/python3" is provided by the "python3"
package.
* On Ubuntu 20.04 (focal) and above, "/usr/bin/python2" is provided by
the "python2" package which has a different name from bionic, and
"/usr/bin/python3" is provided by "python3".
Since the "ubuntu-latest" runner image has a higher version, its
safe to use "python2" or "python3" package name.

There would be a segmentation fault when running p4 v16.2 on ubuntu
22.04 which is the latest version of ubuntu runner image for github
actions.
By checking each version from [1], p4d version 21.1 and above can work
properly on ubuntu 22.04. But version 22.x will break some p4 test
cases. So p4 version 21.x is exactly the version we can use.
With this update, the versions of p4 for Linux and macOS happen to be
the same. So we can add the version number directly into the "P4WHENCE"
variable, and reuse it in p4 installation for macOS.
By removing the "LINUX_P4_VERSION" variable from "ci/lib.sh", the
comment left above has nothing to do with p4, but still applies to
git-lfs. Since we have a fixed version of git-lfs installed on Linux,
we may have a different version on macOS.

When installing p4 as a dependency, we used to pipe output of "p4 -V"
and "p4d -V" to validate the installation and output a condensed version
information. But this would hide potential errors of p4 and would stop
with an empty output. E.g.: p4d version 16.2 running on ubuntu 22.04
causes sigfaults, even before it produces any output.
By removing the pipe after "p4 -V" and "p4d -V", we may get a
verbose output, and stop immediately on errors because we have "set
-e" in "ci/lib.sh". Since we won't look at these trace logs unless
something fails, just including the raw output seems most sensible.

When adding an alternate ODB, we check if the alternate has the same
path as the object dir, and if so, we do nothing. However, that
comparison does not resolve symlinks. This makes it possible to add the
object dir as an alternate, which may result in bad behavior. For
example, it can trick "git repack -a -l -d" (possibly run by "git gc")
into thinking that all packs come from an alternate and delete all
objects.
rm -rf test &&
git clone https://github.com/git/git test &&
(
cd test &&
ln -s objects .git/alt-objects &&
# -c repack.updateserverinfo=false silences a warning about not
# being able to update "info/refs", it isn't needed to show the
# bad behavior
GIT_ALTERNATE_OBJECT_DIRECTORIES=".git/alt-objects" git \
-c repack.updateserverinfo=false repack -a -l -d &&
# It's broken!
git status
# Because there are no more objects!
ls .git/objects/pack
)
Fix this by resolving symlinks and relative paths before comparing the
alternate and object dir. This lets us clean up a number of issues noted
in 37a95862c6 (alternates: re-allow relative paths from environment,
2016-11-07):
- Now that we compare the real paths, duplicate detection is no longer
foiled by relative paths.
- Using strbuf_realpath() allows us to "normalize" paths that
strbuf_normalize_path() can't, so we can stop silently ignoring errors
when "normalizing" paths from the environment.
- We now store an absolute path based on getcwd() (the "future
direction" named in 37a95862c6), so chdir()-ing in the process no
longer changes the directory pointed to by the alternate. This is a
change in behavior, but a desirable one.

For a lot of uses of UNLEAK() it would be quite tricky to release the
memory involved, or we're missing the relevant *_(release|clear)()
functions. But in these cases we have them already, and can just
invoke them on the variable(s) involved, instead of UNLEAK().
For "builtin/worktree.c" the UNLEAK() was also added in [1], but the
struct member it's unleaking was removed in [2]. The only non-"int"
member of that structure is "const char *keep_locked", which comes to
us via "argv" or a string literal[3].
We have good visibility via the compiler and
tooling (e.g. SANITIZE=address) on bad free()-ing, but none on
UNLEAK() we don't need anymore. So let's prefer releasing the memory
when it's easy.
For "bugreport", "worktree" and "config" we need to start using a "ret
= ..." return pattern. For "builtin/bugreport.c" these UNLEAK() were
added in [4], and for "builtin/config.c" in [1].
For "config" the code seen here was the only user of the "value"
variable. For "ACTION_{RENAME,REMOVE}_SECTION" we need to be sure to
return the right exit code in the cases where we were relying on
falling through to the top-level.
I think there's still a use-case for UNLEAK(), but hat it's changed
since then. Using it so that "we can see the real leaks" is
counter-productive in these cases.
It's more useful to have UNLEAK() be a marker of the remaining odd
cases where it's hard to free() the memory for whatever reason. With
this change less than 20 of them remain in-tree.

Fix a leak in the recent 6159e7add4 (rebase --abort: improve reflog
message, 2022-10-12). Before that commit we'd strbuf_release() the
reflog message we were formatting, but when that code was refactored
to use "ropts.head_msg" the strbuf_release() was omitted.
Ideally the three users of "ropts" in cmd_rebase() should use
different "ropts" variables, in practice they're completely separate,
as this and the other user in the "switch" statement will "goto
cleanup", which won't touch "ropts".
The third caller after the "switch" is then unreachable if we take
these two branches, so all of them are getting a "{ 0 }" init'd
"ropts".
So it's OK that we're leaving a stale pointer in "ropts.head_msg",
cleaning it up was our responsibility, and it won't be used again.

When "read_strategy_opts()" is called we may have populated the
"opts->strategy" before, so we'll need to free() it to avoid leaking
memory.
We populate it before because we cal get_replay_opts() from within
"rebase.c" with an already populated "opts", which we then copy. Then
if we're doing a "rebase -i" the sequencer API itself will promptly
clobber our alloc'd version of it with its own.
If this code is changed to do, instead of the added free() here a:
if (opts->strategy)
opts->strategy = xstrdup("another leak");
We get a couple of stacktraces from -fsanitize=leak showing how we

This can be seen in e.g. the 4th test of
"t3404-rebase-interactive.sh".
In the larger picture the ownership of the "struct replay_opts" is
quite a mess, e.g. in this case rebase.c's static "get_replay_opts()"
function partially creates it, but nothing in rebase.c will free()
it. The structure is "mostly owned" by the sequencer API, but it also
expects to get these partially populated versions of it.
It would be better to have rebase keep track of what it allocated, and
free() that, and to pass that as a "const" to the sequencer API, which
would copy what it needs to its own version, and to free() that.
But doing so is a much larger change, and however messy the ownership
boundary is here is consistent with what we're doing already, so let's
just free() this to fix the leak.

- builtin/repack.c: Fix a leak that's been here since this use of
"strbuf_release()" was added in a1bbc6c017 (repack: rewrite the shell
script in C, 2013-09-15). We don't use the variable for anything
except this loop, so we can instead free it right afterwards.
- builtin/rev-parse: Fix a leak that's been here since this code was
added in 21d4783538 (Add a parseopt mode to git-rev-parse to bring
parse-options to shell scripts., 2007-11-04).
- builtin/stash.c: Fix a couple of leaks that have been here since
this code was added in d4788af875 (stash: convert create to builtin,
2019-02-25), we strbuf_release()'d only some of the "struct strbuf" we
allocated earlier in the function, let's release all of them.
- ref-filter.c: Fix a leak in 482c119186 (gpg-interface: improve
interface for parsing tags, 2021-02-11), we don't use the "payload"
variable that we ask parse_signature() to populate for us, so let's
free it.
- t/helper/test-fake-ssh.c: Fix a leak that's been here since this
code was added in 3064d5a38c (mingw: fix t5601-clone.sh,
2016-01-27). Let's free the "struct strbuf" as soon as we don't need
it anymore.

When the "ident" member of the structure was added in
1e8fef609e (untracked cache: guard and disable on system changes,
2015-03-08) this function wasn't updated to free it. Let's do so.
Let's also free the "exclude_per_dir" memory we've been leaking
since[1], while making sure not to free() the constant ".gitignore"
string we add by default[2].
As we now have three struct members we're freeing let's change
free_untracked_cache() to return early if "uc" isn't defined. We won't
hand it to free() now, but that was just for convenience, once we're
dealing with >=2 struct members this pattern is more convenient.

The "sparse_checkout_patterns" member was added to the "struct
index_state" in 836e25c51b (sparse-checkout: hold pattern list in
index, 2021-03-30), but wasn't added to discard_index(). Let's do
that.

The read_cache() in prepare_to_commit() would end up clobbering the
pointer we had for a previously populated "the_index.cache_tree" in
the very common case of "git commit" stressed by e.g. the tests being
changed here.
We'd populate "the_index.cache_tree" by calling
"update_main_cache_tree" in prepare_index(), but would not end up with
a "fully prepared" index. What constitutes an existing index is
clearly overly fuzzy, here we'll check "active_nr" (aka
"the_index.cache_nr"), but our "the_index.cache_tree" might have been
malloc()'d already.
Thus the code added in 11c8a74a64 (commit: write cache-tree data when
writing index anyway, 2011-12-06) would end up allocating the
"cache_tree", and would interact here with code added in
7168624c35 (Do not generate full commit log message if it is not
going to be used, 2007-11-28). The result was a very common memory
leak.

These two built-ins both deal with the index, but weren't discarding
it. In subsequent commits we'll add more free()-ing to discard_index()
that we've missed, but let's first call the existing function.
We can doubtless add discard_index() (or its alias discard_cache()) to
a lot more places, but let's just add it here for now.

This marks tests that have been leak-free since various recent
commits, but which were not marked us such when the memory leak was
fixed. These were mostly discovered with the "check" mode added in
faececa53f (test-lib: have the "check" mode for SANITIZE=leak
consider leak logs, 2022-07-28).
Commits that fixed the last memory leak in these tests. Per narrowing
down when they started to pass under SANITIZE=leak with "bisect":
- t1022-read-tree-partial-clone.sh:
7e2619d8ff (list_objects_filter_options: plug leak of filter_spec
strings, 2022-09-08)
- t4053-diff-no-index.sh: 07a6f94a6d (diff-no-index: release prefixed
filenames, 2022-09-07)
- t6415-merge-dir-to-symlink.sh: bac92b1f39 (Merge branch
'js/ort-clean-up-after-failed-merge', 2022-08-08).
- t5554-noop-fetch-negotiator.sh:
66eede4a37 (prepare_repo_settings(): plug leak of config values,
2022-09-08)
- t2012-checkout-last.sh, t7504-commit-msg-hook.sh,
t91{15,46,60}-git-svn-*.sh: The in-flight "pw/rebase-no-reflog-action"
series, upon which this is based:
https://lore.kernel.org/git/pull.1405.git.1667575142.gitgitgadget@gmail.com/
Let's mark all of these as passing with
"TEST_PASSES_SANITIZE_LEAK=true", to have it regression tested,
including as part of the "linux-leaks" CI job.
Additionally, let's remove the "!SANITIZE_LEAK" prerequisite from
tests that now pass, these were marked as failing in:
- 77e56d55ba (diff.c: fix a double-free regression in a18d66cefb,
2022-03-17)
- c4d1d52631 (tests: change some 'test $(git) = "x"' to test_cmp,
2022-03-07)
These were not spotted with the new "check" mode, but manually, it
doesn't cover these sort of prerequisites. There's few enough that we
shouldn't bother to automate it. They'll be going away sooner than
later.
