When compiling the documentation, asciidoc thinks a backtick surrounded
by whitespace shouldn't be interpreted as marking the start or end of a
literal. In most cases, that's useful behaviour, but in the git-pull
documentation it means asciidoc is failing to correctly detect which
text should be monospaced and which shouldn't.
To avoid this, remove the extraneous spaces from the text to be
monospaced. It would also be possible to fix the formatting by
switching to asciidoc's ++ monospace format markers and still have the
space characters included in the monospace text, but the spaces aren't
necessary and not having them keeps the markup simpler.
Also include a minor grammar fix suggested by Jeff while we're changing
these lines.

Add support for v2 of the PCRE API. This is a new major version of
PCRE that came out in early 2015[1].
The regular expression syntax is the same, but while the API is
similar, pretty much every function is either renamed or takes
different arguments. Thus using it via entirely new functions makes
sense, as opposed to trying to e.g. have one compile_pcre_pattern()
that would call either PCRE v1 or v2 functions.
Git can now be compiled with either USE_LIBPCRE1=YesPlease or
USE_LIBPCRE2=YesPlease, with USE_LIBPCRE=YesPlease currently being a
synonym for the former. Providing both is a compile-time error.
With earlier patches to enable JIT for PCRE v1 the performance of the
release versions of both libraries is almost exactly the same, with
PCRE v2 being around 1% slower.
However after I reported this to the pcre-dev mailing list[2] I got a
lot of help with the API use from Zoltán Herczeg, he subsequently
optimized some of the JIT functionality in v2 of the library.
Running the p7820-grep-engines.sh performance test against the latest
Subversion trunk of both, with both them and git compiled as -O3, and
the test run against linux.git, gives the following results. Just the
/perl/ tests shown:
See commit ("perf: add a comparison test of grep regex engines",
2017-04-19) for details on the machine the above test run was executed
on.
Here HEAD~2 is git with PCRE v1 without JIT, HEAD~ is PCRE v1 with
JIT, and HEAD is PCRE v2 (also with JIT). See previous commits of mine
mentioning p7820-grep-engines.sh for more details on the test setup.
For ease of readability, a different run just of HEAD~ (PCRE v1 with
JIT v.s. PCRE v2), again with just the /perl/ tests shown:
I.e. the two are either neck-to-neck, but PCRE v2 usually pulls ahead,
when it does it's around 20% faster.
A brief note on thread safety: As noted in pcre2api(3) & pcre2jit(3)
the compiled pattern can be shared between threads, but not some of
the JIT context, however the grep threading support does all pattern &
JIT compilation in separate threads, so this code doesn't need to
concern itself with thread safety.
See commit 63e7e9d8b6 ("git-grep: Learn PCRE", 2011-05-09) for the
initial addition of PCRE v1. This change follows some of the same
patterns it did (and which were discussed on list at the time),
e.g. mocking up types with typedef instead of ifdef-ing them out when
USE_LIBPCRE2 isn't defined. This adds some trivial memory use to the
program, but makes the code look nicer.
grep: un-break building with PCRE >= 8.32 without --enable-jit
Amend my change earlier in this series ("grep: add support for the
PCRE v1 JIT API", 2017-04-11) to un-break the build on PCRE v1
versions later than 8.31 compiled without --enable-jit.
As explained in that change and a later compatibility change in this
series ("grep: un-break building with PCRE < 8.32", 2017-05-10) the
pcre_jit_exec() function is a faster path to execute the JIT.
Unfortunately there's no compatibility stub for that function compiled
into the library if pcre_config(PCRE_CONFIG_JIT, &ret) would return 0,
and no macro that can be used to check for it, so the only portable
option to support builds without --enable-jit is via a new
NO_LIBPCRE1_JIT=UnfortunatelyYes Makefile option[1].
Another option would be to make the JIT opt-in via
USE_LIBPCRE1_JIT=YesPlease, after all it's not a default option of
PCRE v1.
I think it makes more sense to make it opt-out since even though it's
not a default option, most packagers of PCRE seem to turn it on by
default, with the notable exception of the MinGW package.
Make the MinGW platform work by default by changing the build defaults
to turn on NO_LIBPCRE1_JIT=UnfortunatelyYes. It is the only platform
that turns on USE_LIBPCRE=YesPlease by default, see commit df5218b4c3 ("config.mak.uname: support MSys2", 2016-01-13) for that
change.

When `git pull --rebase --autostash` in a dirty repository resulted in a
fast-forward, nothing was being autostashed and the pull failed. This
was due to a shortcut to avoid running rebase when we can fast-forward,
but autostash is ignored on that codepath.
Now we will only take the shortcut if autostash is not in effect.
Based on a few tests against the git.git repo, the shortcut does not
seem to give us significant performance benefits, on Linux at least.
Regardless, it is more important to be correct than to be fast.

In builtin/grep.c we parse the config before evaluating the command line
options. This makes the task of teaching grep to respect the new config
option 'submodule.recurse' very easy by just parsing that option.
As an alternative I had implemented a similar structure to treat
submodules as the fetch/push command have, including
* aligning the meaning of the 'recurse_submodules' to possible submodule
values RECURSE_SUBMODULES_* as defined in submodule.h.
* having a callback to parse the value and
* reacting to the RECURSE_SUBMODULES_DEFAULT state that was the initial
state.
However all this is not needed for a true boolean value, so let's keep
it simple. However this adds another place where "submodule.recurse" is
parsed.

docs/config: mention protocol implications of url.insteadOf

It would be nice if we could make this work out of the box,

We already have free_refspec(), a public function which does
the same thing as the static free_refspecs(). Let's just
keep one. There are two minor differences between the
functions:
1. free_refspecs() is a noop when the refspec argument is
NULL. This probably doesn't matter in practice. The
nr_refspec parameter would presumably be 0 in that
case, skipping the loop. And free(NULL) is explicitly
OK. But it doesn't hurt for us to port this extra
safety to free_refspec(), as one of the callers passes
a funny "i+1" count.
2. The order of arguments is reversed between the two
functions. This patch uses the already-public order of
free_refspec(), as it matches the argument order on the
parsing side.

C style: use standard style for "TRANSLATORS" comments
Change all the "TRANSLATORS: [...]" comments in the C code to use the
regular Git coding style, and amend the style guide so that the
example there uses that style.
This custom style was necessary back in 2010 when the gettext support
was initially added, and was subsequently documented in commit cbcfd4e3ea ("i18n: mention "TRANSLATORS:" marker in
Documentation/CodingGuidelines", 2014-04-18).
GNU xgettext hasn't had the parsing limitation that necessitated this
exception for almost 3 years. Since its 0.19 release on 2014-06-02
it's been able to recognize TRANSLATOR comments in the standard Git
comment syntax[1].
Usually we'd like to keep compatibility with software that's that
young, but in this case literally the only person who needs to be
using a gettext newer than 3 years old is Jiang Xin (the only person
who runs & commits "make pot" results), so I think in this case we can
make an exception.
This xgettext parsing feature was added after a thread on the Git
mailing list[2] which continued on the bug-gettext[3] list, but we
never subsequently changed our style & styleguide, do so.
There are already longstanding changes in git that use the standard
comment style & have their TRANSLATORS comments extracted properly
without getting the literal "*"'s mixed up in the text, as would
happen before xgettext 0.19.
Commit 7ff2683253 ("builtin-am: implement -i/--interactive",
2015-08-04) added one such comment, which in commit df0617bfa7 ("l10n:
git.pot: v2.6.0 round 1 (123 new, 41 removed)", 2015-09-05) got picked
up in the po/git.pot file with the right format, showing that Jiang
already runs a modern xgettext.
The xgettext parser does not handle the sort of non-standard comment
style that I'm amending here in sequencer.c, but that isn't standard
Git comment syntax anyway. With this change to sequencer.c & "make
pot" the comment in the pot file is now correct:
#. TRANSLATORS: %s will be "revert", "cherry-pick" or
-#. * "rebase -i".
+#. "rebase -i".

Normally upload-archive forks off upload-archive--writer to
do the real work, and relays any errors back over the
sideband channel. This is a good thing when the command is
properly invoked remotely via ssh or git-daemon. But it's
confusing to curious users who try "git upload-archive -h".
Let's catch this invocation early and give a real usage
message, rather than spewing "-h does not appear to be a git
repository" amidst packet-lines. The chance of a false
positive due to a real client asking for the repo "-h" is
quite small.
Likewise, we'll catch "-h" in upload-archive--writer. People
shouldn't be invoking it manually, but it doesn't hurt to

The git-credential command only takes one argument: the
operation to perform. If we don't have one, we complain
immediately. But if we have one that we don't recognize, we
don't notice until after we've read the credential from
stdin. This is likely to confuse a user invoking "git
credential -h", as the program will hang waiting for their
input before showing anything.
Let's detect this case early. Likewise, we never noticed
when there are extra arguments beyond the one we're
expecting. Let's catch this with the same conditional.
Note that we don't need to handle "--help" similarly,
because the git wrapper does this before even calling
cmd_credential().

If the user provides "-h" on the command line, then our
parse_options() invocation will show a usage message and
quit. But if "-h" is the only argument, the git wrapper
behaves specially: it ignores our RUN_SETUP flag and calls
cmd_am() without having done repository setup at all. This
is due to 99caeed05 (Let 'git <command> -h' show usage
without a git dir, 2009-11-09).
Before cmd_am() calls parse_options(), though, it runs a few
other setup functions. One of these is am_state_init(),
which uses git_pathdup() to set up the default rebase-apply
path. But calling git_pathdup() when we haven't done
repository setup will fall back to using ".git". That's
mostly harmless (since we won't use the value anyway), but
is forbidden since b1ef400eec ("setup_git_env: avoid blind
fall-back to ".git"", 2016-10-20), and we now BUG().
We can't easily move that setup to after the parse_options()
call; the point is to set up defaults that are overwritten
by the option parsing. Instead, we'll detect the "-h" case
early and show the usage then. This matches the behavior of
other builtins which have a similar setup-ordering issue
(e.g., git-branch).

submodule loading: separate code path for .gitmodules and config overlay
The .gitmodules file is not supposed to have all the options available,
that are available in the configuration so separate it out.
A configuration option such as the hypothetical submodule.color.diff
that determines in which color a submodule change is printed,
is a very user specific thing, that the .gitmodules file should
not tamper with.
The .gitmodules file should only be used for settings that required
to setup the project in which the .gitmodules file is tracked. As the
minimum this would only include the name<->path mapping of the
submodule and its URL and branch.
Any further setting (such as 'fetch.recursesubmodules' or
'submodule.<name>.{update, ignore, shallow}') is not specific
to the project setup requirements, but rather is a distribution
of suggested developer configurations. In other areas of Git
a suggested developer configuration is not transported in-tree
but via other means. In an organisation this could be done
by deploying an opinionated system wide config (/etc/gitconfig)
or by putting the settings in the users home directory when
they start at the organisation. In open source projects this
is often accomplished via extensive READMEs (cf. our
SubmittingPatches/CodingGuidlines).
As a later patch in this series wants to introduce
a generic submodule recursion option, we want to make
sure that switch is not exposed via the gitmodules file.

reset/checkout/read-tree: unify config callback for submodule recursion

By putting the callback function there, we no longer need the function
'set_config_update_recurse_submodules', nor duplicate the global variable
in each builtin as well as submodule.c
In the three builtins we have different 2 ways how to load the .gitmodules
and config file, which are slightly different. git-checkout has to load
the submodule config all the time due to 23b4c7bcc5 (checkout: Use
submodule.*.ignore settings from .git/config and .gitmodules, 2010-08-28)
git-reset and git-read-tree do not respect these diff settings, so loading
the submodule configuration is optional. Also put that into submodule.c
for code deduplication.

submodule test invocation: only pass additional arguments
In a later patch we want to introduce a config option to trigger the
submodule recursing by default. As this option should be available and
uniform across all commands that deal with submodules we'd want to test
for this option in the submodule update library.
So instead of calling the whole test set again for
"git -c submodule.recurse foo" instead of "git foo --recurse-submodules",
we'd only want to introduce one basic test that tests if the option is
recognized and respected to not overload the test suite.
Change the test functions by taking only the argument and assemble the
command inside the test function by embedding the arguments into the
command that is "git $arguments --recurse-submodules".
It would be nice to do this for all functions in lib-submodule-update,
but we cannot do that for the non-recursing tests, as there we do not
just pass in a git command but whole functions. (See t3426 for example)

A recent update to t5545-push-options.sh started skipping all the
tests in the script when a web server testing is disabled or
unavailable, not just the ones that require a web server. Non HTTP
tests have been salvaged to always run in this script.

The recently introduced "[includeIf "gitdir:$dir"] path=..."
mechansim has further been taught to take symlinks into account.
The directory "$dir" specified in "gitdir:$dir" may be a symlink to
a real location, not something that $(getcwd) may return. In such
a case, a realpath of "$dir" is compared with the real path of the
current repository to determine if the contents from the named path
should be included.

config: match both symlink & realpath versions in IncludeIf.gitdir:*
There is no good reason why "git fetch $there $sha1" should fail

"git describe --contains" penalized light-weight tags so much that
they were almost never considered. Instead, give them about the
same chance to be considered as an annotated tag that is the same
age as the underlying commit would.

treewide: use is_missing_file_error() where ENOENT and ENOTDIR are checked
Using the is_missing_file_error() helper introduced in the previous
step, update all hits from
$ git grep -e ENOENT --and -e ENOTDIR
There are codepaths that only check ENOENT, and it is possible that
some of them should be checking both. Updating them is kept out of
this step deliberately, as we do not want to change behaviour in this
step.
Our code often opens a path to an optional file, to work on its
contents when we can successfully open it. We can ignore a failure
to open if such an optional file does not exist, but we do want to
report a failure in opening for other reasons (e.g. we got an I/O
error, or the file is there, but we lack the permission to open).
The exact errors we need to ignore are ENOENT (obviously) and
ENOTDIR (less obvious). Instead of repeating comparison of errno
with these two constants, introduce a helper function to do so.
Fixes the test by changing "branch.s/s/dummy" to "branch.s/s.dummy" which is
the right way of accessing config key "branch.s/s.dummy". Purpose of
this test is to confirm that this key doesn't exist after the branch
"s/s" has been renamed to "s".
Earlier it was trying to access invalid config key and hence was getting
an error. However, this wasn't caught because we were expecting the
command to fail for other reason as mentioned above.

Tag objects, which are not reachable from any ref, that point at
missing objects were mishandled by "git gc" and friends (they
should silently be ignored instead)

A test allowed both "git push" and "git receive-pack" on the other
end write their traces into the same file. This is OK on platforms
that allows atomically appending to a file opened with O_APPEND,
but on other platforms led to a mangled output, causing
intermittent test failures. This has been fixed by disabling
traces from "receive-pack" in the test.

"git interpret-trailers", when used as GIT_EDITOR for "git commit
-v", looked for and appended to a trailer block at the very end,
i.e. at the end of the "diff" output. The command has been
corrected to pay attention to the cut-mark line "commit -v" adds to
the buffer---the real trailer block should appear just before it.

"git for-each-ref --format=..." with %(HEAD) in the format used to
