cf2dc1c238 (speed up alt_odb_usable() with many alternates, 2021-07-07)
introduced the function fspathhash() for calculating path hashes while
respecting the configuration option core.ignorecase. Call it instead of
open-coding it; the resulting code is shorter and less repetitive.

With a54e938e5b (strbuf: support long paths w/o read rights in
strbuf_getcwd() on FreeBSD, 2017-03-26) we had t0001 break on systems
like OpenBSD and AIX whose getcwd(3) has standard (but not like glibc
et al) behavior.
This was partially fixed in bed67874e2 (t0001: skip test with
restrictive permissions if getpwd(3) respects them, 2017-08-07).
The problem with that fix is that while its analysis of the problem is
correct, it doesn't actually call getcwd(3), instead it invokes "pwd
-P". There is no guarantee that "pwd -P" is going to call getcwd(3),
as opposed to e.g. being a shell built-in.
On AIX under both bash and ksh this test breaks because "pwd -P" will
happily display the current working directory, but getcwd(3) called by
the "git init" we're testing here will fail to get it.
I checked whether clobbering the $PWD environment variable would
affect it, and it didn't. Presumably these shells keep track of their
working directory internally.
There's possible follow-up work here in teaching strbuf_getcwd() to
get the working directory with whatever method "pwd" uses on these
platforms. See [1] for a discussion of that, but let's take the easy
way out here and just skip these tests by fixing the
GETCWD_IGNORES_PERMS prerequisite to match the limitations of
strbuf_getcwd().

Three hyphens are rendered verbatim, so "--" has to be used to produce a
dash. There is no double arrow ("<->" is rendered as "<→"), so a left
and right arrow "<-->" have to be combined for that.
So fix asciidoc output for special characters. This is similar to fixes
in commit de82095a95 (doc hash-function-transition: fix asciidoc output,
2021-02-05).

This just matches the style/location of the package installation for
other jobs. There should be no functional change.
I did flip the order of the options and command-name ("-y update"
instead of "update -y") for consistency with other lines in the same
file.
Note also that we have to reorder the dependency install with the
"checkout" action, so that we actually have the "ci" scripts available.

The "sparse" workflow runs "apt-get install" to pick up a few necessary
packages. But it needs to run "apt-get update" first, or it risks trying
to download an old package version that no longer exists. And in fact
this happens now, with output like:
2021-07-26T17:40:51.2551880Z E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/c/curl/libcurl4-openssl-dev_7.68.0-1ubuntu2.5_amd64.deb 404 Not Found [IP: 52.147.219.192 80]
2021-07-26T17:40:51.2554304Z E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
Our other ci jobs don't suffer from this; they rely on scripts in ci/,
and ci/install-dependencies does the appropriate "apt-get update".

setup_unpack_trees_porcelain() populates various fields on
unpack_tree_opts, we need to call clear_unpack_trees_porcelain() to
avoid leaking them. Specifically, we used to leak
unpack_tree_opts.msgs_to_free.
We have to do this in leave_reset_head because there are multiple
scenarios where unpack_tree_opts has already been configured, followed
by a 'goto leave_reset_head'. But we can also 'goto leave_reset_head'
prior to having initialised unpack_tree_opts via memset(..., 0, ...).
Therefore we also move unpack_tree_opts initialisation to the start of
reset_head(), and convert it to use brace initialisation - which
guarantees that we can never clear an uninitialised unpack_tree_opts.
clear_unpack_tree_opts() is always safe to call as long as
unpack_tree_opts is at least zero-initialised, i.e. it does not depend
on a previous call to setup_unpack_trees_porcelain().

- cmd_rebase populates rebase_options.strategy with newly allocated
strings, hence we need to free those strings at the end of cmd_rebase
to avoid a leak.
- In some cases: get_replay_opts() is called, which prepares replay_opts
using data from rebase_options. We used to simply copy the pointer
from rebase_options.strategy, however that would now result in a
double-free because sequencer_remove_state() is eventually used to
free replay_opts.strategy. To avoid this we xstrdup() strategy when
adding it to replay_opts.
The original leak happens because we always populate
rebase_options.strategy, but we don't always enter the path that calls
get_replay_opts() and later sequencer_remove_state() - in other words
we'd always allocate a new string into rebase_options.strategy but
only sometimes did we free it. We now make sure that rebase_options
and replay_opts both own their own copies of strategy, and each copy
is free'd independently.
This was first seen when running t0021 with LSAN, but t2012 helped catch
the fact that we can't just free(options.strategy) at the end of
cmd_rebase (as that can cause a double-free). LSAN output from t0021:

apply_multi_file_filter and async_query_available_blobs both query
subprocess output using subprocess_read_status, which writes data into
the identically named filter_status strbuf. We add a strbuf_release to
avoid leaking their contents.

repo_diff_setup() calls through to diff.c's static prep_parse_options(),
which in turn allocates a new array into diff_opts.parseopts.
diff_setup_done() is responsible for freeing that array, and has the
benefit of verifying diff_opts too - hence we add a call to
diff_setup_done() to avoid leaking parseopts.

old_dir/new_dir are free()'d at the end of update_dir_rename_counts,
however if we return early we'll never free those strings. Therefore
we should move all new allocations after the possible early return,
avoiding a leak.
This seems like a fairly recent leak, that started happening since the
early-return was added in:
1ad69eb0dc (diffcore-rename: compute dir_rename_counts in stages, 2021-02-27)
