The option --invert-grep is documented to filter out commits whose
messages match the --grep filters. However, it also affects the
header matches (--author, --committer), which is not intended.
Move the handling of that option to grep.c, as only the code there can
distinguish between matches in the header from those in the message
body. If --invert-grep is given then enable extended expressions (not
the regex type, we just need git grep's --not to work), negate the body
patterns and check if any of them match by piggy-backing on the
collect_hits mechanism of grep_source_1().
Collecting the matches in struct grep_opt is a bit iffy, but with
"last_shown" we have a precedent for writing state information to that
struct.

The comand uses a single instance of rev_info on stack, makes a
single revision traversal and exit. Mark the resources held by the
rev_info structure with UNLEAK().
We do not do this at lower level in revision.c or cmd_log_walk(), as
a new caller of the revision traversal API can make unbounded number
of rev_info during a single run, and UNLEAK() would not a be
suitable mechanism to deal with such a caller.

Earlier we marked that this patch-id test is leak-sanitizer clean,
but if we read the test script carefully, it is merely because we
have too many invocations of commands in the "git log" family on the
upstream side of the pipe, hiding breakages from them.
Split the pipeline so that breakages from these commands can be
caught (not limited to aborts due to leak-sanitizer) and unmark
the script as not passing the test with leak-sanitizer in effect.

RCS keywords are strings that are replaced with information from
Perforce. Examples include $Date$, $Author$, $File$, $Change$ etc.
Perforce resolves these by expanding them with their expanded values
when files are synced, but Git's data model requires these expanded
values to be converted back into their unexpanded form.
Previously, git-p4.py would implement this behaviour through the use of
regular expressions. However, the regular expression substitution was
applied using decoded strings i.e. the content of incoming commit diffs
was first decoded from bytes into UTF-8, processed with regular
expressions, then converted back to bytes.
Not only is this behaviour inefficient, but it is also a cause of a
common issue caused by text files containing invalid UTF-8 data. For
files created in Windows, CP1252 Smart Quote Characters (0x93 and 0x94)
are seen fairly frequently. These codes are invalid in UTF-8, so if the
script encountered any file containing them, on Python 2 the symbols
will be corrupted, and on Python 3 the script will fail with an
exception.
This patch replaces this decoding/encoding with bytes object regular
expressions, so that the substitution is performed directly upon the
source data with no conversions.
A test for smart quote handling has been added to the
t9810-git-p4-rcs.sh test suite.

Change the usage message emitted by "git stash --invalid-option" to
emit usage information for "git stash" in general, and not just for
the "push" command. I.e. before:
$ git stash --invalid-option
error: unknown option `invalid-option'
usage: git stash [push [-p|--patch] [-k|--[no-]keep-index] [-q|--quiet]
[-u|--include-untracked] [-a|--all] [-m|--message <message>]
[--] [<pathspec>...]]
[...]
After:
$ git stash --invalid-option
error: unknown option `invalid-option'
usage: git stash list [<options>]
or: git stash show [<options>] [<stash>]
or: git stash drop [-q|--quiet] [<stash>]
or: git stash ( pop | apply ) [--index] [-q|--quiet] [<stash>]
or: git stash branch <branchname> [<stash>]
or: git stash clear
or: git stash [push [-p|--patch] [-S|--staged] [-k|--[no-]keep-index] [-q|--quiet]
[-u|--include-untracked] [-a|--all] [-m|--message <message>]
[--pathspec-from-file=<file> [--pathspec-file-nul]]
[--] [<pathspec>...]]
or: git stash save [-p|--patch] [-S|--staged] [-k|--[no-]keep-index] [-q|--quiet]
[-u|--include-untracked] [-a|--all] [<message>]
[...]
That we emitted the usage for just "push" in the case of the
subcommand not being explicitly specified was an unintentional
side-effect of how it was implemented. When it was converted to C in
d553f538b8 (stash: convert push to builtin, 2019-02-25) the pattern
of having per-subcommand usage information was rightly continued. The
"git-stash.sh" shellscript did not have that, and always printed the
equivalent of "git_stash_usage".
But in doing so the case of push being implicit and explicit was
conflated. A variable was added to track this in 8c3713cede (stash:
eliminate crude option parsing, 2020-02-17), but it did not update the
usage output accordingly.
This still leaves e.g. "git stash push -h" emitting the
"git_stash_usage" output, instead of "git_stash_push_usage". That
should be fixed, but is a much deeper misbehavior in parse_options()
not being aware of subcommands at all. I.e. in how
PARSE_OPT_KEEP_UNKNOWN and PARSE_OPT_NO_INTERNAL_HELP combine in
commands such as "git stash".
Perhaps PARSE_OPT_KEEP_UNKNOWN should imply
PARSE_OPT_NO_INTERNAL_HELP, or better yet parse_options() should be
extended to fully handle these subcommand cases that we handle
manually in "git stash", "git commit-graph", "git multi-pack-index"
etc. All of those musings would be a much bigger change than this
isolated fix though, so let's leave that for some other time.

The discussion for gpg.ssh.allowedSignersFile shows an example string
that contains "user1@example.com,user2@example.com". Asciidoc thinks
these are real email addresses and generates "mailto" footnotes for
them. This makes the rendered content more confusing, as it has extra
"[1]" markers:
The file consists of one or more lines of principals followed by an
ssh public key. e.g.: user1@example.com[1],user2@example.com[2]
ssh-rsa AAAAX1... See ssh-keygen(1) "ALLOWED SIGNERS" for details.
and also generates pointless notes at the end of the page:
NOTES
1. user1@example.commailto:user1@example.com
2. user2@example.commailto:user2@example.com
We can fix this by putting the example into a backtick literal block.
That inhibits the mailto generation, and as a bonus typesets the example
text in a way that sets it off from the regular prose (a tt font for
html, or bold in the roff manpage).

When serving a fetch, git upload-pack copies data from a git
pack-objects stdout pipe to its stdout. This commit increases the size
of the buffer used for that copying from 8192 to 65515, the maximum
sideband-64k packet size.
Previously, this buffer was allocated on the stack. Because the new
buffer size is nearly 64KB, we switch this to a heap allocation.
On GitLab.com we use GitLab's pack-objects cache which does writes of
65515 bytes. Because of the default 8KB buffer size, propagating these
cache writes requires 8 pipe reads and 8 pipe writes from
git-upload-pack, and 8 pipe reads from Gitaly (our Git RPC service).
If we increase the size of the buffer to the maximum Git packet size,
we need only 1 pipe read and 1 pipe write in git-upload-pack, and 1
pipe read in Gitaly to transfer the same amount of data. In benchmarks
with a pure fetch and 100% cache hit rate workload we are seeing CPU
utilization reductions of over 30%.

The previously suggested workflow:
git sparse-checkout init ...
git sparse-checkout set ...
Suffered from three problems:
1) It would delete nearly all files in the first step, then
restore them in the second. That was poor performance and
forced unnecessary rebuilds.
2) The two-step process resulted in two progress bars, which
was suboptimal from a UI point of view for wrappers that
invoked both of these commands but only exposed a single
command to their end users.
3) With cone mode, the first step would delete nearly all
ignored files everywhere, because everything was considered
to be outside of the specified sparsity paths. (The user was
not allowed to specify any sparsity paths in the `init` step.)
Avoid these problems by teaching `set` to understand the extra
parameters that `init` takes and performing any necessary initialization
if not already in a sparse checkout.

However, we would like sparse_checkout_set() to do the same work that

To facilitate this transition, give each mode their own copy of the
