Fix a leak in the recent 6159e7add49 (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.

sequencer.c: fix "opts->strategy" leak in read_strategy_opts()
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
ended up clobbering the already allocated value, i.e.:

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.

commit: discard partial cache before (re-)reading it
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 11c8a74a64a (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 7168624c353 (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.

Commits that fixed the last memory leak in these tests. Per narrowing
down when they started to pass under SANITIZE=leak with "bisect":

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

- c4d1d526312 (tests: change some 'test $(git) = "x"' to test_cmp,

doesn't cover these sort of prerequisites. There's few enough that we

sequencer: stop exporting GIT_REFLOG_ACTION
Each time it picks a commit the sequencer copies the GIT_REFLOG_ACITON
environment variable so it can temporarily change it and then restore
the previous value. This results in code that is hard to follow and also
leaks memory because (i) we fail to free the copy when we've finished
with it and (ii) each call to setenv() leaks the previous value. Instead
pass the reflog action around in a variable and use it to set
GIT_REFLOG_ACTION in the child environment when running "git commit".
Within the sequencer GIT_REFLOG_ACTION is no longer set and is only read
by sequencer_reflog_action(). It is still set by rebase before calling
the sequencer, that will be addressed in the next commit. cherry-pick
and revert are unaffected as they do not set GIT_REFLOG_ACTION before
calling the sequencer.

make the test a bit more lenient and test for the latter instead of the
former, which works around these CI issues.

t5516: move plaintext-password tests from t5601 and t5516
Commit 6dcbdc0d66 (remote: create fetch.credentialsInUrl config,
2022-06-06) added tests for our handling of passwords in URLs. Since the
obvious URL to be affected is git-over-http, the tests use http. However
they don't set up a test server; they just try to access
https://localhost, assuming it will fail (because the nothing is
listening there).
This causes some possible problems:
- There might be a web server running on localhost, and we do not
actually want to connect to that.
- The DNS resolver, or the local firewall, might take a substantial
amount of time (or forever, whichever comes first) to fail to
connect, slowing down the tests cases unnecessarily.
- Since there's no server, our tests for "allow" and "warn" still
expect the clone/fetch/push operations to fail, even though in the
real world we'd expect these to succeed. We scrape stderr to see
what happened, but it's not as robust as a more realistic test.
Let's instead move these to t5551, which is all about testing http and
where we have a real server. That eliminates any issues with contacting
a strange URL, and lets the "allow" and "warn" tests confirm that the
operation actually succeeds.
It's not quite a verbatim move for a few reasons:
- we can drop the LIBCURL dependency; it's already part of
lib-httpd.sh
- we'll use HTTPD_URL_USER_PASS, etc, instead of our fake URL. To
avoid repetition, we'll add a few extra variables.
- the "https://username:@localhost" test uses a funny URL that
lib-httpd.sh doesn't provide. We'll similarly construct it in a
variable. Note that we're hard-coding the lib-httpd username here,
but t5551 already does that everywhere.
- for the "domain:port" test, the URL provided by lib-httpd is fine,
since our test server will always be on an exotic port. But we'll
confirm in the test that this is so.
- since our message-matching is done via grep, I simplified it to use
a regex, rather than trying to massage lib-httpd's variables.
Arguably this makes it more readable, too, while retaining the bits
we care about: the fatal/warning distinction, the "uses plaintext"
message, and the fact that the password was redacted.
- we'll use the /auth/ path for the repo, which shows that we are
indeed making use of the auth information when needed.
- we'll also use /smart/; most of these tests could be done via /dumb/
in t5550, but setting up pushes there requires extra effort and
dependencies. The smart protocol is what most everyone is using
these days anyway.
This patch is my own, but I stole the analysis and a few bits of the
commit message from a patch by Johannes Schindelin.

branch: error copying or renaming a detached HEAD
In c847f53712 (Detached HEAD (experimental), 2007-01-01) an error
condition was introduced in rename_branch() to prevent renaming, later
also copying, a detached HEAD.
The condition used was checking for NULL in oldname, the source branch
to rename/copy. That condition cannot be satisfied because if no source
branch is specified, HEAD is going to be used in the call.
The error issued instead is:
fatal: Invalid branch name: 'HEAD'
Let's remove the condition in copy_or_rename_branch() (the current
function name) and check for HEAD before calling it, dying with the
original intended error if we're in a detached HEAD.

Documentation: add lint-fsck-msgids
During the initial development of the fsck-msgids.txt feature, it
has become apparent that it is very much error prone to make sure
the description in the documentation file are sorted and correctly
match what is in the fsck.h header file.
Add a quick-and-dirty Perl script and doc-lint target to sanity
check that the fsck-msgids.txt is consistent with the error type
list in the fsck.h header file.

fsck: document msg-id
The documentation lacks mention of specific <msg-id> that are supported.
While git-help --config will display a list of these options, often
developers' first instinct is to consult the git docs to find valid
config values.
Add a list of fsck error messages, and link to it from the git-fsck
documentation.
