sha1_file: drop experimental GIT_USE_LOOKUP search
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.

config: make git_{config,parse}_maybe_bool equivalent
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
it as git_parse_maybe_bool", 2015-08-19) intended git_parse_maybe_bool
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
need.
t5334: document that git push --signed=1 does not work
When accepting booleans as command-line or config options throughout
Git, there are several documented synonyms for true and false.
However, one particular user is slightly broken: `git push --signed=..`
does not understand the integer synonyms for true and false.
This is hardly wanted. The --signed option has a different notion of
boolean than all other arguments and config options, including the
config option corresponding to it, push.gpgSign.

Doc/git-{push,send-pack}: correct --sign= to --signed=
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.
We want to make sure that people who copy & paste code would see
fewer instances of "git-foo". The use of these dashed forms have
been discouraged since v1.6.0 days.

git.c: ignore pager.* when launching builtin as dashed external
When running, e.g., `git -c alias.bar=foo bar`, we expand the alias and
execute `git-foo` as a dashed external. This is true even if git foo is
a builtin. That is on purpose, and is motivated in a comment which was
added in commit 441981bc ("git: simplify environment save/restore
logic", 2016-01-26).
Shortly before we launch a dashed external, and unless we have already
found out whether we should use a pager, we check `pager.foo`. This was
added in commit 92058e4d ("support pager.* for external commands",
2011-08-18). If the dashed external is a builtin, this does not match
that commit's intention and is arguably wrong, since it would be cleaner
if we let the "dashed external builtin" handle `pager.foo`.
This has not mattered in practice, but a recent patch taught `git-tag`
to ignore `pager.tag` under certain circumstances. But, when started
using an alias, it doesn't get the chance to do so, as outlined above.
That recent patch added a test to document this breakage.
Do not check `pager.foo` before launching a builtin as a dashed
external, i.e., if we recognize the name of the external as a builtin.

Using, e.g., `git -c pager.tag tag -a new-tag` results in errors such as

Someone who makes use of both `git tag -a` and `git tag -l` will
probably not set `pager.tag`, so that `git tag -a` will actually work,
at the cost of not paging output of `git tag -l`.
Use the mechanisms introduced in two earlier patches to ignore
`pager.tag` in git.c and let the `git tag` builtin handle it on its own.
Only respect `pager.tag` when running in list-mode.
There is a window between where the pager is started before and after
this patch. This means that early errors can behave slightly different
before and after this patch. Since operation-parsing has to happen
inside this window, this can be seen with `git -c pager.tag="echo pager
is used" tag -l --unknown-option`. This change in paging-behavior should
be acceptable since it only affects erroneous usages.
Update the documentation and update tests.
If an alias is used to run `git tag -a`, then `pager.tag` will still be
respected. Document this known breakage. It will be fixed in a later
commit. Add a similar test for `-l`, which works.

more arguments which imply -l, but using these two should be enough.)
Third, use -a as a representative for "not -l". Actually, the tests use
`git tag -am` so no editor is launched, but that is irrelevant, since we
just want to see whether the pager is used or not. Make one of the tests

The previous patch introduced a way for builtins to declare that they

Provide setup_auto_pager(), which builtins can call in order to handle
`pager.<cmd>`, including possibly starting the pager. Make this function
don't do anything if a pager has already been started, as indicated by
use_pager or pager_in_use().
Whenever this function is called from a builtin, git.c will already have
called commit_pager_choice(). Since commit_pager_choice() treats the
special value -1 as "punt" or "not yet decided", it is not a problem
that we might end up calling commit_pager_choice() once in git.c and
once (or more) in the builtin. Make the new function use -1 in the same
way and document it as "punt".

git.c: let builtins opt for handling `pager.foo` themselves
Before launching a builtin git foo and unless mechanisms with precedence
are in use, we check for and handle the `pager.foo` config. This is done
without considering exactly how git foo is being used, and indeed, git.c
cannot (and should not) know what the arguments to git foo are supposed
to achieve.
In practice this means that, e.g., `git -c pager.tag tag -a new-tag`
results in errors such as "Vim: Warning: Output is not to a terminal"
and a garbled terminal. Someone who makes use of both `git tag -a` and
`git tag -l` will probably not set `pager.tag`, so that `git tag -a`
will actually work, at the cost of not paging output of `git tag -l`.
To allow individual builtins to make more informed decisions about when
to respect `pager.foo`, introduce a flag DELAY_PAGER_CONFIG. If the flag
is set, do not check `pager.foo`.
Do not check for DELAY_PAGER_CONFIG in `execv_dashed_external()`. That
call site is arguably wrong, although in a way that is not yet visible,
and will be changed in a slightly different direction in a later patch.
Don't add any users of DELAY_PAGER_CONFIG just yet, one will follow in a

revision: do not fallback to default when rev_input_given is set
If revs->def is set (as it is in "git log") and there are no
pending objects after parsing the user's input, then we show
whatever is in "def". But if the user _did_ ask for some
input that just happened to be empty (e.g., "--glob" that
does not match anything), showing the default revision is
confusing. We should just show nothing, as that is what the
user's request yielded.

rev-list: don't show usage when we see empty ref patterns
If the user gives us no starting point for a traversal, we
want to complain with our normal usage message. But if they
tried to do so with "--all" or "--glob", but that happened
not to match any refs, the usage message isn't helpful. We
should just give them the empty output they asked for
instead.

Normally a caller that invokes setup_revisions() has to
check rev.pending to see if anything was actually queued for
the traversal. But they can't tell the difference between
two cases:
1. The user gave us no tip from which to start a
traversal.
2. The user tried to give us tips via --glob, --all, etc,
but their patterns ended up being empty.
Let's set a flag in the rev_info struct that callers can use
to tell the difference. We can set this from the
init_all_refs_cb() function. That's a little funny because
it's not exactly about initializing the "cb" struct itself.
But that function is the common setup place for doing
pattern traversals that is used by --glob, --all, etc.

t6018: flesh out empty input/output rev-list tests
In 751a2ac6e (rev-list --exclude: tests, 2013-11-01), we
added a few tests for handling "empty" inputs with rev-list
(i.e., where the user gave us some pattern but it turned out
not to queue any objects for traversal), all of which were
marked as failing.
In preparation for working on this area of the code, let's
give each test a more descriptive name. Let's also include
one more case which we should cover: feeding a --glob
pattern that doesn't match anything.
We can also drop the explanatory comment; we'll be
converting these to expect_success in the next few patches,
so the discussion isn't necessary.

Using test_commit is simpler than chaining echo && git add &&
test_tick && commit. Also having tags makes it clearer which commit
is being selecting by reset.

Interactive rebase was ignoring '--rerere-autoupdate'. Fix this by
reading it appropriate file when restoring the sequencer state for an
interactive rebase and passing '--rerere-autoupdate' to merge and
cherry-pick when rebasing with '--preserve-merges'.

Rebase accepts '--rerere-autoupdate' as an option but only honors it
if '-m' is also given. Fix it for a non-interactive rebase by passing
on the option to 'git am' and 'git cherry-pick'. Rework the tests so
that they can be used for each rebase flavor and extend them.

submodule: merge repo_read_gitmodules and gitmodules_config
Since 69aba5329 (submodule: add repo_read_gitmodules) there have been
two ways to load a repository's .gitmodules file:
'repo_read_gitmodules()' is used if you have a repository object you are
working with or 'gitmodules_config()' if you are implicitly working with
'the_repository'. Merge the logic of these two functions to remove
duplicate code.
In addition, 'repo_read_gitmodules()' can segfault by passing in a NULL
pointer to 'git_config_from_file()' if a repository doesn't have a
worktree. Instead check for the existence of a worktree before
attempting to load the .gitmodules file.

submodule: remove submodule.fetchjobs from submodule-config parsing
The '.gitmodules' file should only contain information pertinent to
configuring individual submodules (name to path mapping, URL where to
obtain the submodule, etc.) while other configuration like the number of
jobs to use when fetching submodules should be a part of the
repository's config.
Remove the 'submodule.fetchjobs' configuration option from the general
submodule-config parsing and instead rely on using the
'config_from_gitmodules()' in order to maintain backwards compatibility
with this config being placed in the '.gitmodules' file.
