builtin/repack.c: add cruft packs to MIDX during geometric repack
When using cruft packs, the following race can occur when a geometric
repack that writes a MIDX bitmap takes place afterwords:
- First, create an unreachable object and do an all-into-one cruft
repack which stores that object in the repository's cruft pack.
- Then make that object reachable.
- Finally, do a geometric repack and write a MIDX bitmap.
Assuming that we are sufficiently unlucky as to select a commit from the
MIDX which reaches that object for bitmapping, then the `git
multi-pack-index` process will complain that that object is missing.
The reason is because we don't include cruft packs in the MIDX when
doing a geometric repack. Since the "make that object reachable" doesn't
necessarily mean that we'll create a new copy of that object in one of
the packs that will get rolled up as part of a geometric repack, it's
possible that the MIDX won't see any copies of that now-reachable
object.
Of course, it's desirable to avoid including cruft packs in the MIDX
because it causes the MIDX to store a bunch of objects which are likely
to get thrown away. But excluding that pack does open us up to the above
race.
This patch demonstrates the bug, and resolves it by including cruft
packs in the MIDX even when doing a geometric repack.

builtin/pack-objects.c: --cruft with expiration
In a previous patch, pack-objects learned how to generate a cruft pack
so long as no objects are dropped.
This patch teaches pack-objects to handle the case where a non-never
`--cruft-expiration` value is passed. This case is slightly more
complicated than before, because we want pack-objects to save
unreachable objects which would have been pruned when there is another
recent (i.e., non-prunable) unreachable object which reaches the other.
We'll call these objects "unreachable but reachable-from-recent".
Here is how pack-objects handles `--cruft-expiration`:
- Instead of adding all objects outside of the kept pack(s) into the
packing list, only handle the ones whose mtime is within the grace
period.
- Construct a reachability traversal whose tips are the
unreachable-but-recent objects.
- Then, walk along that traversal, stopping if we reach an object in
the kept pack. At each step along the traversal, we add the object
we are visiting to the packing list.
In the majority of these cases, any object we visit in this traversal
will already be in our packing list. But we will sometimes encounter
reachable-from-recent cruft objects, which we want to retain even if
they aged out of the grace period.
The most subtle point of this process is that we actually don't need to
bother to update the rescued object's mtime. Even though we will write
an .mtimes file with a value that is older than the expiration window,
it will continue to survive cruft repacks so long as any objects which
reach it haven't aged out.
That is, a future repack will also exclude that object from the initial
packing list, only to discover it later on when doing the reachability
traversal.
Finally, stopping early once an object is found in a kept pack is safe
to do because the kept packs ordinarily represent which packs will
survive after repacking. Assuming that it _isn't_ safe to halt a
traversal early would mean that there is some ancestor object which is
missing, which implies repository corruption (i.e., the complete set of
reachable objects isn't present).

reachable: report precise timestamps from objects in cruft packs
When generating a cruft pack, the caller within pack-objects will want
to know the precise timestamps of cruft objects (i.e., their
corresponding values in the .mtimes table) rather than the mtime of the
cruft pack itself.
Teach add_recent_packed() to lookup each object's precise mtime from the
.mtimes file if one exists (indicated by the is_cruft bit on the
packed_git structure).
A couple of small things worth noting here:
- load_pack_mtimes() needs to be called before asking for
nth_packed_mtime(), and that call is done lazily here. That function
exits early if the .mtimes file has already been opened and parsed,
so only the first call is slow.
- Checking the is_cruft bit can be done without any extra work on the
caller's behalf, since it is set up for us automatically as a
side-effect of calling add_packed_git() (just like the 'pack_keep'
and 'pack_promisor' bits).

reachable: add options to add_unseen_recent_objects_to_traversal
This function behaves very similarly to what we will need in
pack-objects in order to implement cruft packs with expiration. But it
is lacking a couple of things. Namely, it needs:
- a mechanism to communicate the timestamps of individual recent
objects to some external caller
- and, in the case of packed objects, our future caller will also want
to know the originating pack, as well as the offset within that pack
at which the object can be found
- finally, it needs a way to skip over packs which are marked as kept
in-core.
To address the first two, add a callback interface in this patch which
reports the time of each recent object, as well as a (packed_git,
off_t) pair for packed objects.
Likewise, add a new option to the packed object iterators to skip over
packs which are marked as kept in core. This option will become

builtin/pack-objects.c: --cruft without expiration
Teach `pack-objects` how to generate a cruft pack when no objects are
dropped (i.e., `--cruft-expiration=never`). Later patches will teach
`pack-objects` how to generate a cruft pack that prunes objects.
When generating a cruft pack which does not prune objects, we want to
collect all unreachable objects into a single pack (noting and updating
their mtimes as we accumulate them). Ordinary use will pass the result
of a `git repack -A` as a kept pack, so when this patch says "kept
pack", readers should think "reachable objects".
Generating a non-expiring cruft packs works as follows:
- Callers provide a list of every pack they know about, and indicate
which packs are about to be removed.
- All packs which are going to be removed (we'll call these the
redundant ones) are marked as kept in-core.
Any packs the caller did not mention (but are known to the
`pack-objects` process) are also marked as kept in-core. Packs not
mentioned by the caller are assumed to be unknown to them, i.e.,
they entered the repository after the caller decided which packs
should be kept and which should be discarded.
Since we do not want to include objects in these "unknown" packs
(because we don't know which of their objects are or aren't
reachable), these are also marked as kept in-core.
- Then, we enumerate all objects in the repository, and add them to
our packing list if they do not appear in an in-core kept pack.
This results in a new cruft pack which contains all known objects that
aren't included in the kept packs. When the kept pack is the result of
`git repack -A`, the resulting pack contains all unreachable objects.

separator, meaning one of the tests added by 48803821b1 ("completion:

that include backslashes unless both FUNNYNAMES is set and the system is
not Cygwin.
It might be nice to have more granularity than "FUNNYNAMES" and its

Documentation/Makefile: fix "make info" regression in dad9cd7d518
Fix a regression in my dad9cd7d518 (Makefile: move ".SUFFIXES" rule to
shared.mak, 2022-03-03). As explained in the GNU make documentation
for the $* variable, available at:
info make --index-search='$*'
This rule relied on ".texi" being in the default list of suffixes, as
seen at:
The documentation explains what was going on here:
In an explicit rule, there is no stem; so '$*' cannot be determined
in that way. Instead, if the target name ends with a recognized
suffix (*note Old-Fashioned Suffix Rules: Suffix Rules.), '$*' is
set to the target name minus the suffix. For example, if the
target name is 'foo.c', then '$*' is set to 'foo', since '.c' is a
suffix. GNU 'make' does this bizarre thing only for compatibility
with other implementations of 'make'. You should generally avoid
using '$*' except in implicit rules or static pattern rules.
If the target name in an explicit rule does not end with a
recognized suffix, '$*' is set to the empty string for that rule.
I.e. this rule added back in 5cefc33bffd (Documentation: add
gitman.info target, 2007-12-10) was resolving gitman.texi from
gitman.info. We can instead just use the more obvious $< variable
referring to the prerequisite.
This was the only use of $* in our Makefiles in an explicit rule, the

depend on the ".SUFFIXES" list.

configure.ac: fix HAVE_SYNC_FILE_RANGE definition
If sync_file_range is not available when building the configure script,
there is a cosmetic bug when running that script reporting
"HAVE_SYNC_FILE_RANGE: command not found". Remove that error message by
defining HAVE_SYNC_FILE_RANGE to an empty string, rather than generating
a script where that appears as a bare command.

git-compat-util: really support openssl as a source of entropy
05cd988dce5 (wrapper: add a helper to generate numbers from a CSPRNG,
2022-01-17), configure openssl as the source for entropy in NON-STOP
but doesn't add the needed header or link options.
Since the only system that is configured to use openssl as a source
of entropy is NON-STOP, add the header unconditionally, and -lcrypto
to the list of external libraries.
An additional change is required to make sure a NO_OPENSSL=1 build
will be able to work as well (tested on Linux with a modified value
of CSPRNG_METHOD = openssl), and the more complex logic that allows
for compatibility with APPLE_COMMON_CRYPTO or allowing for simpler
ways to link (without libssl) has been punted for now.

In 9c4d58ff2c (ls-tree: split up "fast path" callbacks, 2022-03-23), a
refactoring of the various read_tree_at() callbacks caused us to
unconditionally recurse into directories if `-l` (long format) was
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.
