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.

Enable ref-filter to process multiple merged and no-merged filters, and
extend functionality to git branch, git tag and git for-each-ref. This
provides an easy way to check for branches that are "graduation
candidates:"
$ git branch --no-merged master --merged next
If passed more than one merged (or more than one no-merged) filter, refs
must be reachable from any one of the merged commits, and reachable from
none of the no-merged commits.

Add tests covering the behavior of passing multiple contains/no-contains
filters to git branch, e.g.:
$ git branch --contains feature_a --contains feature_b
$ git branch --no-contains feature_a --no-contains feature_b
When passed more than one contains (or no-contains) filter, the tips of
the branches returned must be reachable from any of the contains commits
and from none of the the no-contains commits.
This logic is useful to describe prior to enabling multiple
merged/no-merged filters, so that future tests will demonstrate
consistent behavior between merged/no-merged and contains/no-contains
filters.

"git status" has trouble showing where it came from by interpreting
reflog entries that recordcertain events, e.g. "checkout @{u}", and
gives a hard/fatal error. Even though it inherently is impossible
to give a correct answer because the reflog entries lose some
information (e.g. "@{u}" does not record what branch the user was
on hence which branch 'the upstream' needs to be computed, and even
if the record were available, the relationship between branches may
have changed), at least hide the error to allow "status" show its
output.

A popular way of partially staging a new file is to run `git add -N
<path>` and then use the hunk editing of `git add -p` to select the
part of the file that the user wishes to stage. Since
85953a3187 ("diff-files --raw: show correct post-image of
intent-to-add files", 2020-07-01) this has stopped working as
intent-to-add paths are now show as new files rather than changes to
an empty blob and `git apply` refused to apply a creation patch for a
path that was marked as intent-to-add. 7cfde3fa0f ("apply: allow "new
file" patches on i-t-a entries", 2020-08-06) fixed the problem with
apply but it still wasn't possible to edit the added hunk properly.
2c8bd8471a ("checkout -p: handle new files correctly", 2020-05-27)
had previously changed `add -p` to handle new files but it did not
implement patch editing correctly. The perl version simply forbade
editing and the C version opened the editor with the full diff rather
that just the hunk which meant that the user had to edit the hunk
header manually to get it to work.
The root cause of the problem is that added files store the diff header
with the hunk data rather than separating the two as we do for other
changes. Changing added files to store the diff header separately
fixes the editing problem at the expense of having to special case
empty additions as they no longer have any hunks associated with them,
only the diff header.
The changes move some existing code into a conditional changing the
indentation, they are best viewed with
--color-moved-ws=allow-indentation-change (or --ignore-space-change
works well to get an overview of the changes)

but it currently fails for the wrong reason.

Our color tests of "git add -p" do something a bit different from how a
normal user would behave: we pretend there's a pager in use, so that Git
thinks it's OK to write color to a non-tty stdout. This comes from
8539b46534 (t3701: avoid depending on the TTY prerequisite, 2019-12-06),
which allows us to avoid a lot of complicated mock-tty code.
However, those environment variables also make their way down to
sub-processes of add--interactive, including the "diff-files" we run to
generate the patches. As a result, it thinks it should output color,
too. So in t3701.50, for example, the machine-readable version of the
diff we get unexpectedly has color in it. We fail to parse it as a diff
and think there are zero hunks.
The test does still pass, though, because even with zero hunks we'll
dump the diff header (and we consider those unparseable bits to be part
of the header!), and so the output still has the expected color codes in
it. We don't notice that the command was totally broken and failed to
apply anything.
And in fact we're not really testing what we think we are about the
color, either. While add--interactive does correctly show the version we
got from running "diff-files --color", we'd also pass the test if we had
accidentally shown the machine-readable version, too, since it
(erroneously) has color codes in it.
One could argue that the test isn't very realistic; it's setting up this
"pretend there's a pager" situation to get around the tty restrictions
of the test environment. So one option would be to move back towards
using a real tty. But the behavior of add--interactive really is
user-visible here. If a user, for whatever reason, did run "git
--paginate add --patch" (perhaps because their pager is really a filter
or something), the command would totally fail to do anything useful.
Since we know that we don't want color in this output, let's just make
add--interactive more defensive, and say "--no-color" explicitly. It
doesn't hurt anything in the common case, but it fixes this odd case and
lets our test function properly again.
Note that the C builtin run_add_p() already passes --no-color, so it
doesn't need a similar fix. That will eventually replace this perl code
anyway, but the test change here will be valuable for ensuring that.

After applying hunks to a file with "add -p", the C patch_update_file()
function tries to refresh the index (just like the perl version does).
We can only refresh the index if we're able to read it in, so we first
check the return value of repo_read_index(). But unlike many functions,
where "0" is success, that function is documented to return the number
of entries in the index. Hence we should be checking for success with a
non-negative return value.
Neither the tests nor any users seem to have noticed this, probably due
to a combination of:
- this affects only the C version, which is not yet the default
- following it up with any porcelain command like "git diff" or "git
commit" would refresh the index automatically.
But you can see the problem by running the plumbing "git diff-files"
immediately after "add -p" stages all hunks. Running the new test with
GIT_TEST_ADD_I_USE_BUILTIN=1 fails without the matching code change.

When a user checks out the upstream branch of HEAD, the upstream branch
not being a local branch, and then runs "git status", like this:
git clone $URL client
cd client
git checkout @{u}
git status
no status is printed, but instead an error message:
fatal: HEAD does not point to a branch
(This error message when running "git branch" persists even after
checking out other things - it only stops after checking out a branch.)
This is because "git status" reads the reflog when determining the "HEAD
detached" message, and thus attempts to DWIM "@{u}", but that doesn't
work because HEAD no longer points to a branch.
Therefore, when calculating the status of a worktree, tolerate dangling
marks. This is done by adding an additional parameter to
dwim_ref() and repo_dwim_ref().

887952b8c6 ("fetch: optionally allow disabling FETCH_HEAD update",
2020-08-18) introduced the ability to disable writing to FETCH_HEAD
during fetch, but did not suppress the "<source> -> FETCH_HEAD" message
when this ability is used. This message is misleading in this case,
because FETCH_HEAD is not written. Also, because "fetch" is used to
lazy-fetch missing objects in a partial clone, this significantly
clutters up the output in that case since the objects to be fetched are
potentially numerous.
Therefore, suppress this message when --no-write-fetch-head is passed
(but not when --dry-run is set).

The intention of `git init --separate-work-dir=<path>` is to move the
.git/ directory to a location outside of the main worktree. When used
within a linked worktree, however, rather than moving the .git/
directory as intended, it instead incorrectly moves the worktree's
.git/worktrees/<id> directory to <path>, thus disconnecting the linked
worktree from its parent repository and breaking the worktree in the
process since its local .git file no longer points at a location at
which it can find the object database. Fix this broken behavior.
An intentional side-effect of this change is that it also closes a
loophole not caught by ccf236a23a (init: disallow --separate-git-dir
with bare repository, 2020-08-09) in which the check to prevent
--separate-git-dir being used in conjunction with a bare repository was
unable to detect the invalid combination when invoked from within a
linked worktree. Therefore, add a test to verify that this loophole is
closed, as well.

A linked worktree's .git file is a "gitfile" pointing at the
.git/worktrees/<id> directory within the repository. When `git init
--separate-git-dir=<path>` is used on an existing repository to relocate
the repository's .git/ directory to a different location, it neglects to
update the .git files of linked worktrees, thus breaking the worktrees
by making it impossible for them to locate the repository. Fix this by
teaching --separate-git-dir to repair the .git file of each linked
worktree to point at the new repository location.

The .git/worktrees/<id>/gitdir file points at the location of a linked
worktree's .git file. Its content must be of the form
/path/to/worktree/.git (from which the location of the worktree itself
can be derived by stripping the "/.git" suffix). If the gitdir file is
deleted or becomes corrupted or outdated, then Git will be unable to
find the linked worktree. An easy way for the gitdir file to become
outdated is for the user to move the worktree manually (without using
"git worktree move"). Although it is possible to manually update the
gitdir file to reflect the new linked worktree location, doing so
requires a level of knowledge about worktree internals beyond what a
user should be expected to know offhand.
Therefore, teach "git worktree repair" how to repair broken or outdated
.git/worktrees/<id>/gitdir files automatically. (For this to work, the
command must either be invoked from within the worktree whose gitdir
file requires repair, or from within the main or any linked worktree by
providing the path of the broken worktree as an argument to "git
worktree repair".)

If a worktree's .git file is deleted or becomes corrupted or outdated,

Currently, ref-filter only supports printing email with angle brackets.
Let's add support for two more email options.
- trim : for email without angle brackets.
- localpart : for the part before the @ sign out of trimmed email

The 'grep' check in test 4 of t7421 resulted in the failure of t7421 on
Windows due to a different error message
error: cannot spawn git: No such file or directory
instead of
fatal: exec 'rev-parse': cd to 'my-subm' failed: No such file or directory
Tighten up the check to compute 'src_abbrev' by guarding the
'verify_submodule_committish()' call using `p->status !='D'`, so that
the former isn't called in case of non-existent submodule directory,
consequently, there is no such error message on any execution
environment. The same need not be implemented for 'dst_abbrev' and is
rather redundant since the conditional 'if (S_ISGITLINK(p->mod_dst))'
already guards the 'verify_submodule_committish()' when we have a
status of 'D'.
Therefore, eliminate the 'grep' check in t7421. Instead, verify the
absence of an error message by doing a 'test_must_be_empty' on the
file containing the error.
