In 83bbf9b92ea8 (mergetool--lib: improve support for vimdiff-style tool
variants, 2020-07-29), we introduced a `list_tool_variants` function
in the spirit of Postel's Law: be lenient in what you accept as input.
In this particular instance, we wanted to allow not only `bc` but also
`bc3` as name for the Beyond Compare tool.
However, what this patch overlooked is that it is totally allowed for
users to override the defaults in `mergetools/`. But now that we strip
off trailing digits, the name that the user gave the tool might not
actually be in the list produced by `list_tool_variants`.
So let's do the same as for the `diff_cmd` and the `merge_cmd`: override
it with the trivial version in case a user-defined setup was detected.

As of 83bbf9b92ea8 (mergetool--lib: improve support for vimdiff-style
tool variants, 2020-07-29), we already list `bc` and `bc3` as aliases
for that mergetool/difftool.
However, the current Beyond Compare version is _4_, therefore the `bc4`
alias is missing from that list.
Most notably, this is the root cause of the breakage reported in
https://github.com/git-for-windows/git/issues/2893 where a
well-configured `bc4` difftool stopped working as of v2.29.0:
`setup_tool` would notice that after stripping off the trailing digit,
it finds a match in `mergetools/` (the `bc` file), source it, and then
the alias would not match the list offered by the `list_tool_variants`
function, and simply exit without doing anything, but pretending
success.

Now that hashamp has lazy initialization and a HASHMAP_INIT macro,
hashmaps allocated on the stack can be initialized without a call to
hashmap_init() and in some cases makes the code a bit shorter. Convert
some callsites over to take advantage of this.

By default, we do not use a mempool and strdup_strings is true; in this
case, we can avoid both an extra allocation and an extra free by just
over-allocating for the strmap_entry leaving enough space at the end to
copy the key. FLEXPTR_ALLOC_STR exists for exactly this purpose, so
make use of it.
Also, adjust the case when we are using a memory pool and strdup_strings
is true to just do one allocation from the memory pool instead of two so
that the strmap_clear() and strmap_remove() code can just avoid freeing
the key in all cases.

For heavy users of strmaps, allowing the keys and entries to be

In 1af265f0 (compat/bswap.h: simplify MSVC endianness
detection, 2020-11-08) we attempted to simplify code by assuming MSVC
builds will be for little-endian machines, since only unusably old
versions of MSVC supported big-endian MIPS and m68k architectures.
However, it's possible that MSVC could be ported to build for a
big-endian architecture again, so the simplification wasn't as
future-proof as hoped.
So let's go back to the old way of detecting MSVC, and then checking
architecture from a list of little-endian architecture macros.
Note that MSVC does not treat ARM64 as bi-endian, so we can safely treat
it as little-endian.

We taught rev-list a new way to separate options from revisions in
19e8789b23 (revision: allow --end-of-options to end option parsing,
2019-08-06), but rev-parse uses its own parser. It should know about
--end-of-options not only for consistency, but because it may be
presented with similarly ambiguous cases. E.g., if a caller does:
git rev-parse "$rev" -- "$path"
to parse an untrusted input, then it will get confused if $rev contains
an option-like string like "--local-env-vars". Or even "--not-real",
which we'd keep as an option to pass along to rev-list.
Or even more importantly:
git rev-parse --verify "$rev"
can be confused by options, even though its purpose is safely parsing
untrusted input. On the plus side, it will always fail the --verify
part, as it will not have parsed a revision, so the caller will
generally "fail closed" rather than continue to use the untrusted
string. But it will still trigger whatever option was in "$rev"; this
should be mostly harmless, since rev-parse options are all read-only,
but I didn't carefully audit all paths.
This patch lets callers write:
git rev-parse --end-of-options "$rev" -- "$path"
and:
git rev-parse --verify --end-of-options "$rev"
which will both treat "$rev" always as a revision parameter. The latter
is a bit clunky. It would be nicer if we had defined "--verify" to
require that its next argument be the revision. But we have not
historically done so, and:
git rev-parse --verify -q "$rev"
does currently work. I added a test here to confirm that we didn't break
that.
A few implementation notes:
- We don't document --end-of-options explicitly in commands, but rather
in gitcli(7). So I didn't give it its own section in git-rev-parse(1).
But I did call it out specifically in the --verify section, and
include it in the examples, which should show best practices.
- We don't have to re-indent the main option-parsing block, because we
can combine our "did we see end of options" check with "does it start
with a dash". The exception is the pre-setup options, which need
their own block.
- We do however have to pull the "--" parsing out of the "does it start
with dash" block, because we want to parse it even if we've seen
--end-of-options.
- We'll leave "--end-of-options" in the output. This is probably not
technically necessary, as a careful caller will do:
git rev-parse --end-of-options $revs -- $paths
and anything in $revs will be resolved to an object id. However, it
does help a slightly less careful caller like:
git rev-parse --end-of-options $revs_or_paths
where a path "--foo" will remain in the output as long as it also
exists on disk. In that case, it's helpful to retain --end-of-options
to get passed along to rev-list, s it would otherwise see just
"--foo".

The option-parsing loop of rev-parse checks whether the first character
of an arg is "-". If so, then it enters a series of conditionals
checking for individual options. But some options are inexplicably
outside of that outer conditional.
This doesn't produce the wrong behavior; the conditional is actually
redundant with the individual option checks, and it's really only its
fallback "continue" that we care about. But we should at least be
consistent.
One obvious alternative is that we could get rid of the conditional
entirely. But we'll be using the extra block it provides in the next
patch.

Because of the order in which we check options in rev-parse, there are a
few options we accept even after a "--". This is wrong, because the
whole point of "--" is to say "everything after here is a path". Let's
move the "did we see a dashdash" check (it's called "as_is" in the code)
to the top of the parsing loop.
Note there is one subtlety here. The options are ordered so that some
are checked before we even see if we're in a repository (they continue
the loop, and if we get past a certain point, then we do the repository
setup). By moving the as_is check higher, it's also in that "before
setup" section, even though it might look at the repository via
verify_filename(). However, this works out: we'd never set as_is until
we parse "--", and we don't parse that until after doing the setup.
An alternative here to avoid the subtlety is to put the as_is check at
the top of the post-setup options. But then every pre-setup option would
have to remember to check "if (!as_is && !strcmp(...))". So while this
is a bit magical, it's harder for future code to get wrong.
