Update the ref sorting functions of 'ref-filter.c' so that when date fields
are specified with a format string (such as in 'git for-each-ref
--sort=creatordate:<something>'), they are sorted by their formatted string
value rather than by the underlying numeric timestamp. Currently, date
fields are always sorted by timestamp, regardless of whether formatting
information is included in the '--sort' key.
Leaving the default (unformatted) date sorting unchanged, sorting by the
formatted date string adds some flexibility to 'for-each-ref' by allowing
for behavior like "sort by year, then by refname within each year" or "sort
by time of day". Because the inclusion of a format string previously had no
effect on sort behavior, this change likely will not affect existing usage
of 'for-each-ref' or other ref listing commands.
Additionally, update documentation & tests to document the new sorting
mechanism.

SSH signer did not. Even though we already fixed the caller that
assumed only a negative return value is an error, tighten the callee
to signal an error with a negative return as well. This way, the

The command "git tag -s" internally calls sign_buffer() to make a
cryptographic signature using the chosen backend like GPG and SSH.
The internal helper functions used by "git tag" implementation seem
to use a "negative return values are errors, zero or positive return
values are not" convention, and there are places (e.g., verify_tag()
that calls gpg_verify_tag()) that these internal helper functions
translate return values that signal errors to conform to this
convention, but do_sign() that calls sign_buffer() forgets to do so.
Fix it, so that a failed call to sign_buffer() that can return the
exit status from pipe_command() will not be overlooked.

"git show-ref --verify" is useful for scripts that want to look up a

of comparing the refname to "HEAD" we can accept all one-level refs that
contain only uppercase ascii letters and underscores.

Contributors using Gitgitgadget continue to send single-commit PRs with
their commit message text duplicated below the three-dash line,
increasing the signal-to-noise ratio for reviewers.
This is because Gitgitgadget copies the pull request description as an
in-patch commentary, for single-commit PRs, and _GitHub_ defaults to
prefilling the pull request description with the commit message, for
single-commit PRs (followed by the content of the pull request
template).
Add a note in the pull request template mentioning that for
single-commit PRs, the PR description should thus be kept empty, in the
hope that contributors read it and act on it.

- We use a scoped error variable `e` which is hard to reason about.
This variable is not required at all.

The `stack_compact_range()` function receives a "first" and "last" index
that indicates which tables of the reftable stack should be compacted.
Naturally, "first" must be smaller than "last" in order to identify a
proper range of tables to compress, which we indeed also assert in the
function. But the validations happens after we have already allocated
arrays with a size of `last - first + 1`, leading to an underflow and
thus an invalid allocation size.
Fix this by reordering the array allocations to happen after we have
validated parameters. While at it, convert the array allocations to use
the newly introduced macros.
Note that the relevant variables pointing into arrays should also be
converted to use `size_t` instead of `int`. This is left for a later
commit in this series.

Similar to the preceding commit, let's carry over macros to allocate
arrays with `REFTABLE_ALLOC_ARRAY()` and `REFTABLE_CALLOC_ARRAY()`. This
requires us to change the signature of `reftable_calloc()`, which only
takes a single argument right now and thus puts the burden on the caller
to calculate the final array's size. This is a net improvement though as
it means that we can now provide proper overflow checks when multiplying
the array size with the member size.
Convert callsites of `reftable_calloc()` to the new signature and start
using the new macros where possible.

Throughout the reftable library we have many cases where we need to grow
arrays. In order to avoid too many reallocations, we roughly double the
capacity of the array on each iteration. The resulting code pattern is
duplicated across many sites.
We have similar patterns in our main codebase, which is why we have
eventually introduced an `ALLOC_GROW()` macro to abstract it away and
avoid some code duplication. We cannot easily reuse this macro here
though because `ALLOC_GROW()` uses `REALLOC_ARRAY()`, which in turn will
call realloc(3P) to grow the array. The reftable code is structured as a
library though (even if the boundaries are fuzzy), and one property this
brings with it is that it is possible to plug in your own allocators. So
instead of using realloc(3P), we need to use `reftable_realloc()` that
knows to use the user-provided implementation.
So let's introduce two new macros `REFTABLE_REALLOC_ARRAY()` and
`REFTABLE_ALLOC_GROW()` that mirror what we do in our main codebase,
with two modifications:
- They use `reftable_realloc()`, as explained above.
- They use a different growth factor of `2 * cap + 1` instead of `(cap
+ 16) * 3 / 2`.
The second change is because we know a bit more about the allocation
patterns in the reftable library. In most cases, we end up only having a
handful of items in the array and don't end up growing them. The initial
capacity that our normal growth factor uses (which is 24) would thus end
up over-allocating in a lot of code paths. This effect is measurable:
- Before change:
HEAP SUMMARY:
in use at exit: 671,983 bytes in 152 blocks
total heap usage: 3,843,446 allocs, 3,843,294 frees, 223,761,402 bytes allocated
- After change with a growth factor of `(2 * alloc + 1)`:
HEAP SUMMARY:
in use at exit: 671,983 bytes in 152 blocks
total heap usage: 3,843,446 allocs, 3,843,294 frees, 223,761,410 bytes allocated
- After change with a growth factor of `(alloc + 16)* 2 / 3`:
HEAP SUMMARY:
in use at exit: 671,983 bytes in 152 blocks
total heap usage: 3,833,673 allocs, 3,833,521 frees, 4,728,251,742 bytes allocated
While the total heap usage is roughly the same, we do end up allocating
significantly more bytes with our usual growth factor (in fact, roughly
21 times as many).
Convert the reftable library to use these new macros.

The git-stash(1) command needs to write to the index for many of its
operations. When the index is locked by a concurrent writer it will thus
fail to operate, which is expected. What is not expected though is that
we do not print any error message at all in this case. The user can thus
easily miss the fact that the command didn't do what they expected it to
do and would be left wondering why that is.
Fix this bug and report failures to write to the index. Add tests for
the subcommands which hit the respective code paths.
While at it, unify error messages when writing to the index fails. The
chosen error message is already used in "builtin/stash.c".

Now that multi-pack reuse is supported, enable it via the
feature.experimental configuration in addition to the classic
`pack.allowPackReuse`.
This will allow more users to experiment with the new behavior who might
not otherwise be aware of the existing `pack.allowPackReuse`
configuration option.
The enum with values NO_PACK_REUSE, SINGLE_PACK_REUSE, and
MULTI_PACK_REUSE is defined statically in builtin/pack-objects.c's
compilation unit. We could hoist that enum into a scope visible from the
repository_settings struct, and then use that enum value in
pack-objects. Instead, define a single int that indicates what
pack-objects's default value should be to avoid additional unnecessary
code movement.
Though `feature.experimental` implies `pack.allowPackReuse=multi`, this
can still be overridden by explicitly setting the latter configuration
to either "single" or "false". Tests covering all of these cases are
