78a26cb720 Merge branch 'sh/mergetool-hideresolved'
"git mergetool" feeds three versions (base, local and remote) of
a conflicted path unmodified.  The command learned to optionally
prepare these files with unconflicted parts already resolved.

* sh/mergetool-hideresolved:
  mergetool: add per-tool support and overrides for the hideResolved flag
  mergetool: break setup_tool out into separate initialization function
  mergetool: add hideResolved configuration

dadc91ff0c Merge branch 'js/range-diff-one-side-only'
The "git range-diff" command learned "--(left|right)-only" option
to show only one side of the compared range.

* js/range-diff-one-side-only:
  range-diff: offer --left-only/--right-only options
  range-diff: move the diffopt initialization down one layer
  range-diff: combine all options in a single data structure
  range-diff: simplify code spawning `git log`
  range-diff: libify the read_patches() function again
  range-diff: avoid leaking memory in two error code paths

77348b0e6e Merge branch 'js/range-diff-wo-dotdot'
There are other ways than ".." for a single token to denote a
"commit range", namely "<rev>^!" and "<rev>^-<n>", but "git
range-diff" did not understand them.

* js/range-diff-wo-dotdot:
  range-diff(docs): explain how to specify commit ranges
  range-diff/format-patch: handle commit ranges other than A..B
  range-diff/format-patch: refactor check for commit range

69571dfe21 Merge branch 'jt/clone-unborn-head'
"git clone" tries to locally check out the branch pointed at by
HEAD of the remote repository after it is done, but the protocol
did not convey the information necessary to do so when copying an
empty repository.  The protocol v2 learned how to do so.

* jt/clone-unborn-head:
  clone: respect remote unborn HEAD
  connect, transport: encapsulate arg in struct
  ls-refs: report unborn targets of symrefs

9d336655ba doc: fix naming of response-end-pkt
Git Protocol version 2[1] defines 0002 as a Message Packet that indicates
the end of a response for stateless connections.

Change the naming of the 0002 Packet to 'Response End' to match the
parsing introduced in Wireshark's MR !1922 for consistency. A subsequent
MR in Wireshark will address additional mismatches.

669b458755 docs/rev-list: add an examples section
We currently don't show any examples of using git-rev-list at all. Let's
add some pretty elementary examples. They likely seem obvious to anybody
who has worked with the tool for a while, but my purpose here is
two-fold:

  - they may be enlightening to people who haven't used the tool a lot
    to give a general flavor of how it is meant to be used

  - they can serve as a starting point for adding more interesting
    examples (we can do that without the basic ones, of course, but I
    think it makes sense to show off the building blocks)

This set is far from exhaustive, but again, the purpose is to be a
starting point for further additions.

452d26448d rev-list-options.txt: fix rendering of bonus paragraph
In git-log(1) -- but not in git-shortlog(1) or git-rev-list(1) -- we
include a bonus paragraph in the description of `--first-parent`. But
we forgot to add a lone "+" for a list continuation, and we shouldn't
be indenting this second paragraph. As a result, we get a different
indentation and the `backticks` render literally.

1eb4136ac2 diff: --{rotate,skip}-to=<path>
In the implementation of "git difftool", there is a case where the
user wants to start viewing the diffs at a specific path and
continue on to the rest, optionally wrapping around to the
beginning.  Since it is somewhat cumbersome to implement such a
feature as a post-processing step of "git diff" output, let's
support it internally with two new options.

 - "git diff --rotate-to=C", when the resulting patch would show
   paths A B C D E without the option, would "rotate" the paths to
   shows patch to C D E A B instead.  It is an error when there is
   no patch for C is shown.

 - "git diff --skip-to=C" would instead "skip" the paths before C,
   and shows patch to C D E.  Again, it is an error when there is no
   patch for C is shown.

 - "git log [-p]" also accepts these two options, but it is not an
   error if there is no change to the specified path.  Instead, the
   set of output paths are rotated or skipped to the specified path
   or the first path that sorts after the specified path.

ee82a487f6 ref-filter: use pretty.c logic for trailers
Now, ref-filter is using pretty.c logic for setting trailer options.

New to ref-filter:
  :key=<K> - only show trailers with specified key.
  :valueonly[=val] - only show the value part.
  :separator=<SEP> - inserted between trailer lines.
  :key_value_separator=<SEP> - inserted between key and value in trailer lines

Enhancement to existing options(now can take value and its optional):
  :only[=val]
  :unfold[=val]

'val' can be: true, on, yes or false, off, no.

Currently, the options for the `list` and `show` subcommands are just
listed as `<options>`. This seems to imply, from a cursory glance at the
summary, that they take the stash options listed below. However, reading
more carefully, we see that they take log options and diff options
respectively.

Make it more obvious that they take log and diff options by explicitly
stating this in the subcommand summary.

16950f8384 rev-list: add --disk-usage option for calculating disk usage
It can sometimes be useful to see which refs are contributing to the
overall repository size (e.g., does some branch have a bunch of objects
not found elsewhere in history, which indicates that deleting it would
shrink the size of a clone).

You can find that out by generating a list of objects, getting their
sizes from cat-file, and then summing them, like:

    git rev-list --objects --no-object-names main..branch
    git cat-file --batch-check='%(objectsize:disk)' |
    perl -lne '$total += $_; END { print $total }'

Though note that the caveats from git-cat-file(1) apply here. We "blame"
base objects more than their deltas, even though the relationship could
easily be flipped. Still, it can be a useful rough measure.

But one problem is that it's slow to run. Teaching rev-list to sum up
the sizes can be much faster for two reasons:

  1. It skips all of the piping of object names and sizes.

  2. If bitmaps are in use, for objects that are in the
     bitmapped packfile we can skip the oid_object_info()
     lookup entirely, and just ask the revindex for the
     on-disk size.

This patch implements a --disk-usage option which produces the same
answer in a fraction of the time. Here are some timings using a clone of
torvalds/linux:

  [rev-list piped to cat-file, no bitmaps]
  $ time git rev-list --objects --no-object-names --all |
    git cat-file --buffer --batch-check='%(objectsize:disk)' |
    perl -lne '$total += $_; END { print $total }'
  1459938510
  real	0m29.635s
  user	0m38.003s
  sys	0m1.093s

  [internal, no bitmaps]
  $ time git rev-list --disk-usage --objects --all
  1459938510
  real	0m31.262s
  user	0m30.885s
  sys	0m0.376s

Even though the wall-clock time is slightly worse due to parallelism,
notice the CPU savings between the two. We saved 21% of the CPU just by
avoiding the pipes.

But the real win is with bitmaps. If we use them without the new option:

  [rev-list piped to cat-file, bitmaps]
  $ time git rev-list --objects --no-object-names --all --use-bitmap-index |
    git cat-file --batch-check='%(objectsize:disk)' |
    perl -lne '$total += $_; END { print $total }'
  1459938510
  real	0m6.244s
  user	0m8.452s
  sys	0m0.311s

then we're faster to generate the list of objects, but we still spend a
lot of time piping and looking things up. But if we do both together:

  [internal, bitmaps]
  $ time git rev-list --disk-usage --objects --all --use-bitmap-index
  1459938510
  real	0m0.219s
  user	0m0.169s
  sys	0m0.049s

then we get the same answer much faster.

For "--all", that answer will correspond closely to "du objects/pack",
of course. But we're actually checking reachability here, so we're still
fast when we ask for more interesting things:

  $ time git rev-list --disk-usage --use-bitmap-index v5.0..v5.10
  374798628
  real	0m0.429s
  user	0m0.356s
  sys	0m0.072s

I had interpreted that as saying that the objects that notes were

`git worktree list` now annotates worktrees as prunable, shows
locked and prunable attributes in --porcelain mode, and gained
a --verbose option.

* rs/worktree-list-verbose:
  worktree: teach `list` verbose mode
  worktree: teach `list` to annotate prunable worktree
  worktree: teach `list --porcelain` to annotate locked worktree
  t2402: ensure locked worktree is properly cleaned up
  worktree: teach worktree_lock_reason() to gently handle main worktree
  worktree: teach worktree to lazy-load "prunable" reason

a38cb9878a mailmap: only look for .mailmap in work tree
When trying to find a .mailmap file, we will always look for it in the
current directory. This makes sense in a repository with a working tree,
since we'd always go to the toplevel directory at startup. But for a
bare repository, it can be confusing. With an option like --git-dir (or
$GIT_DIR in the environment), we don't chdir at all, and we'd read
.mailmap from whatever directory you happened to be in before starting
Git.

(Note that --git-dir without specifying a working tree historically
means "the current directory is the root of the working tree", but most
bare repositories will have core.bare set these days, meaning they will
realize there is no working tree at all).

The documentation for gitmailmap(5) says:

  If the file `.mailmap` exists at the toplevel of the repository[...]

which likewise reinforces the notion that we are looking in the working
tree.

This patch prevents us from looking for such a file when we're in a bare
repository. This does break something that used to work:

  cd bare.git
  git cat-file blob HEAD:.mailmap >.mailmap
  git shortlog

But that was never advertised in the documentation. And these days we
have mailmap.blob (which defaults to HEAD:.mailmap) to do the same thing
in a much cleaner way.

However, there's one more interesting case: we might not have a
repository at all! The git-shortlog command can be run with git-log
output fed on its stdin, and it will apply the mailmap. In that case, it
probably does make sense to read .mailmap from the current directory.
This patch will continue to do so.

That leads to one even weirder case: if you run git-shortlog to process
stdin, the input _could_ be from a different repository entirely. Should
we respect the in-tree .mailmap then? Probably yes. Whatever the source
of the input, if shortlog is running in a repository, the documentation
claims that we'd read the .mailmap from its top-level (and of course
it's reasonably likely that it _is_ from the same repo, and the user
just preferred to run git-log and git-shortlog separately for whatever
reason).

The included test covers these cases, and we now document the "no repo"
case explicitly.

We also add a test that confirms we find a top-level ".mailmap" even
when we start in a subdirectory of the working tree. This worked both
before and after this commit, but we never tested it explicitly (it
works because we always chdir to the top-level of the working tree if
there is one).

acc1c4d5d4 maintenance: incremental strategy runs pack-refs weekly
When the 'maintenance.strategy' config option is set to 'incremental',
a default maintenance schedule is enabled. Add the 'pack-refs' task to
that strategy at the weekly cadence.
