"diff-highlight" (in contrib/) had a logic to flush its output upon
seeing a blank line but the way it detected a blank line was broken.
* jk/diff-highlight-blank-match-fix:
diff-highlight: correctly match blank lines for flush

"git push" that wants to be atomic and wants to send push
certificate learned not to prepare and sign the push certificate
when it fails the local check (hence due to atomicity it is known
that no certificate is needed).

send-pack: run GPG after atomic push checking

The "unshelve" subcommand of "git p4" used incorrectly used
commit^N where it meant to say commit~N to name the Nth generation
ancestor, which has been corrected.
* ld/p4-unshelve-fix:
git-p4: use HEAD~$n to find parent commit for unshelve
git-p4 unshelve: adding a commit breaks git-p4 unshelve

"git receive-pack" that accepts requests by "git push" learned to
outsource most of the ref updates to the new "proc-receive" hook.
* jx/proc-receive-hook:
doc: add documentation for the proc-receive hook
transport: parse report options for tracking refs
t5411: test updates of remote-tracking branches
receive-pack: new config receive.procReceiveRefs
doc: add document for capability report-status-v2
New capability "report-status-v2" for git-push

A "git gc"'s big brother has been introduced to take care of more
repository maintenance tasks, not limited to the object database
cleaning.
* ds/maintenance-part-1:
maintenance: add trace2 regions for task execution
maintenance: add auto condition for commit-graph task
maintenance: use pointers to check --auto
maintenance: create maintenance.<task>.enabled config

"git fetch --all --ipv4/--ipv6" forgot to pass the protocol options
to instances of the "git fetch" that talk to individual remotes,
which has been corrected.

"git remote set-head" that failed still said something that hints
the operation went through, which was misleading.

There is a logic to estimate how many objects are in the
repository, which is mean to run once per process invocation, but
it ran every time the estimated value was requested.

"git for-each-ref" and friends that list refs used to allow only
one --merged or --no-merged to filter them; they learned to take
combination of both kind of filtering.
* al/ref-filter-merged-and-no-merged:
Doc: prefer more specific file name
ref-filter: make internal reachable-filter API more precise
ref-filter: allow merged and no-merged filters

The 'meld' backend of the "git mergetool" learned to give the
underlying 'meld' the '--auto-merge' option, which would help
reduce the amount of text that requires manual merging.

"format-patch --range-diff=<prev> <origin>..HEAD" has been taught

We try to flush the output from diff-highlight whenever we see a blank
line. That lets you see the output for each commit as soon as it is
generated, even if Git is still chugging away at a diff, or traversing
to find the next commit.
However, our "blank line" match checks length($_). That won't ever be
true, because we haven't chomped the line ending. As a result, we never
flush. Instead, let's use a simple regex which handles line endings in
with the end-of-line marker.
This has been broken since the initial version in 927a13fe87 (contrib:
add diff highlight script, 2011-10-18). Probably nobody noticed because:
- most output is big enough, or comes fast enough, that it flushes
anyway. And it can be difficult to notice the difference between
"show a commit, then pause" and "pause, then show two commits". I
only noticed because I was viewing "git log" output on a repo with a
very slow textconv filter.
- if stdout is going to the terminal (and not another pager like
less), then the flush isn't necessary. So any manual testing would
show it appearing to work.
You can easily see the difference with something like:
echo '* diff=slow' >>.gitattributes
git -c diff.slow.textconv='sleep 1; cat' \
-c pager.log='diff-highlight | less' \
log -p
That should generate one commit every second or so (more if it touches
multiple files), but without this patch it waits for many seconds before
generating several pages of output.

The refs update commands can be sent to the server side in two different
ways: GPG-signed or unsigned. We should run these two operations in the
same "Finally, tell the other end!" code block, but they are seperated
by the "Clear the status for each ref" code block. This will result in
a slight performance loss, because the failed atomic push will still
perform unnecessary preparations for shallow advertise and GPG-signed
commands buffers, and user may have to be bothered by the (possible) GPG
passphrase input when there is nothing to sign.
Add a new test case to t5534 to ensure GPG will not be called when the
GPG-signed atomic push fails.

The internal reachable-filter API is a bit loose and imprecise; it
also bleeds unnecessarily into the public header. Tighten the API
by:
* renaming do_merge_filter() to reach_filter()
* separating parameters to explicitly identify what data is used
by the function instead of passing an entire ref_filter_cbdata
struct
* renaming and moving internal constants from header to source
file

The completion for format-patch currently suggests --base=, --interdiff=
and --range-diff= as options. However, with these `=` forms of the
options, there is no space and we'd enter the `--*` case which means we
don't call the __git_complete_revlist() at the end.
Teach _git_format_patch() to complete refs in the case of --base=,
--interdiff= and --range-diff=.

The approximate_object_count() function tries to compute the count only
once per process. But ever since it was introduced in 8e3f52d778
(find_unique_abbrev: move logic out of get_short_sha1(), 2016-10-03), we
failed to actually set the "valid" flag, meaning we'd compute it fresh
on every call.
This turns out not to be _too_ bad, because we're only iterating through
the packed_git list, and not making any system calls. But since it may
get called for every abbreviated hash we output, even this can add up if
you have many packs.
Here are before-and-after timings for a new perf test which just asks
rev-list to abbreviate each commit hash (the test repo is linux.git,
with commit-graphs):
Test origin HEAD
----------------------------------------------------------------------------
5303.3: rev-list (1) 28.91(28.46+0.44) 29.03(28.65+0.38) +0.4%
5303.4: abbrev-commit (1) 1.18(1.06+0.11) 1.17(1.02+0.14) -0.8%
5303.7: rev-list (50) 28.95(28.56+0.38) 29.50(29.17+0.32) +1.9%
5303.8: abbrev-commit (50) 3.67(3.56+0.10) 3.57(3.42+0.15) -2.7%
5303.11: rev-list (1000) 30.34(29.89+0.43) 30.82(30.35+0.46) +1.6%
5303.12: abbrev-commit (1000) 86.82(86.52+0.29) 77.82(77.59+0.22) -10.4%
5303.15: load 10,000 packs 0.08(0.02+0.05) 0.08(0.02+0.06) +0.0%
It doesn't help at all when we have 1 pack (5303.4), but we get a 10%
speedup when there are 1000 packs (5303.12). That's a modest speedup for
a case that's already slow and we'd hope to avoid in general (note how
slow it is even after, because we have to look in each of those packs
for abbreviations). But it's a one-line change that clearly matches the
original intent, so it seems worth doing.
The included perf test may also be useful for keeping an eye on any
regressions in the overall abbreviation code.
