Long ago in 628522ec14 (sha1-lookup: more memory efficient
search in sorted list of SHA-1, 2007-12-29) we added
sha1_entry_pos(), a binary search that uses the uniform
distribution of sha1s to scale the selection of mid-points.
As this was a performance experiment, we tied it to the
GIT_USE_LOOKUP environment variable and never enabled it by
default.
This code was successful in reducing the number of steps in
each search. But the overhead of the scaling ends up making
it slower when the cache is warm. Here are best-of-five
timings for running rev-list on linux.git, which will have
to look up every object:
$ time git rev-list --objects --all >/dev/null
real 0m35.357s
user 0m35.016s
sys 0m0.340s
$ time GIT_USE_LOOKUP=1 git rev-list --objects --all >/dev/null
real 0m37.364s
user 0m37.045s
sys 0m0.316s
The USE_LOOKUP version might have more benefit on a cold
cache, as the time to fault in each page would dominate. But
that would be for a single lookup. In practice, most
operations tend to look up many objects, and the whole pack
.idx will end up warm.
It's possible that the code could be better optimized to
compete with a naive binary search for the warm-cache case,
and we could have the best of both worlds. But over the
years nobody has done so, and this is largely dead code that
is rarely run outside of the test suite. Let's drop it in
the name of simplicity.
This lets us remove sha1_entry_pos() entirely, as the .idx
lookup code was the only caller. Note that sha1-lookup.c
still contains sha1_pos(), which differs from
sha1_entry_pos() in two ways:
- it has a different interface; it uses a function pointer
to access sha1 entries rather than a size/offset pair
describing the table's memory layout
- it only scales the initial selection of "mi", rather
than each iteration of the search
We can't get rid of this function, as it's called from
several places. It may be that we could replace it with a
simple binary search, but that's out of scope for this patch
(and would need benchmarking).

In 1a812f3a70 (hashcmp(): inline memcmp() by hand to
optimize, 2011-04-28), it was reported that an open-coded
loop outperformed memcmp() for comparing sha1s.
Discussion[1] a few years later in 2013 showed that this
depends on your libc's version of memcmp(). In particular,
glibc 2.13 optimized their memcmp around 2011. Here are
current timings with glibc 2.24 (best-of-five, on
linux.git):
[before this patch, open-coded]
$ time git rev-list --objects --all
real 0m35.357s
user 0m35.016s
sys 0m0.340s
[after this patch, memcmp]
real 0m32.930s
user 0m32.630s
sys 0m0.300s
Now that we've had 6 years for that version of glibc to
make its way onto people's machines, it's worth revisiting
our benchmarks and switching to memcmp().
It may be that there are other non-glibc systems where
memcmp() isn't as well optimized. But since our single data
point in favor of open-coding was on a now-ancient glibc, we
should probably assume the system memcmp is good unless
proven otherwise. We may end up with a SLOW_MEMCMP Makefile
knob, but we can hold off on that until we actually find
such a system in practice.

find_pack_entry_one() uses the fan-out table of pack indexes to find out
which entries match the first byte of the searched hash and does a
binary search on this subset of the main index table.
If there are no matching entries then lo and hi will have the same
value. The binary search still starts and compares the hash of the
following entry (which has a non-matching first byte, so won't cause any
trouble), or whatever comes after the sorted list of entries.
The probability of that stray comparison matching by mistake is low, but
let's not take any chances and check when entering the binary search
loop if we're actually done already.

Both of these act on a string `value` which they parse as a boolean. The
"parse"-variant was introduced as a replacement for the "config"-variant
which for historical reasons takes an unused argument `name`. That it
was intended as a replacement is not obvious from commit 9a549d43
("config.c: rename git_config_maybe_bool_text and export it as
git_parse_maybe_bool", 2015-08-19), but that is what the background on
the mailing list suggests [1].
However, these two functions do not parse `value` in exactly the same
way. In particular, git_config_maybe_bool accepts integers (0 for false,
non-0 for true). This means there are two slightly different definitions
of "maybe_bool" in the code-base, and that every time a call to
git_config_maybe_bool is changed to use git_parse_maybe_bool, it risks
breaking someone's workflow.
Move the implementation of "config" into "parse" and make the latter a
trivial wrapper.
This also fixes the only user of git_parse_maybe_bool, `git push
--signed=..`.

Commit 9a549d43 ("config.c: rename git_config_maybe_bool_text and export

to be a replacement for git_config_maybe_bool, which could then be
retired. That is not obvious from the commit message, but that is what
the background on the mailing list suggests [1].
However, git_{config,parse}_maybe_bool do not handle all input the same.
Before the rename, that was by design and there is a caller in config.c
which requires git_parse_maybe_bool to behave exactly as it does.
Prepare for the next patch by renaming git_parse_maybe_bool to ..._text
and reimplementing the first one as a simple call to the second one. Let
the existing users in config.c use ..._text, since it does what they

Since we're about to touch the behavior of --signed=, do this as a
preparatory step.
The documentation mentions --sign=, and it works. But that's just
because it's an unambiguous abbreviation of --signed, which is how it is
actually implemented. This was added in commit 30261094 ("push: support
signing pushes iff the server supports it", 2015-08-19). Back when that
series was developed [1] [2], there were suggestions about both --sign=
and --signed=. The final implementation settled on --signed=, but some
of the documentation and commit messages ended up using --sign=.
The option is referred to as --signed= in Documentation/config.txt
(under push.gpgSign).
One could argue that we have promised --sign for two years now, so we
should implement it as an alias for --signed. (Then we might also
deprecate the latter, something which was considered already then.) That
would be a slightly more intrusive change.
This minor issue would only be a problem once we want to implement some
other option --signfoo, but the earlier we do this step, the better.
