commit-graph.c: display correct number of chunks when writing
chunk-format: add technical docs
chunk-format: restore duplicate chunk checks
midx: use 64-bit multiplication for chunk sizes

commit-graph: use chunk-format read API
chunk-format: create read chunk API
midx: use chunk-format API in write_midx_internal()
midx: drop chunk progress during write
midx: return success/failure in chunk write methods
midx: add num_large_offsets to write_midx_context
midx: add pack_perm to write_midx_context
midx: add entries to write_midx_context
midx: use context in write_midx_pack_names()

commit-graph: use chunk-format write API
chunk-format: create chunk format write API
commit-graph: anonymize data in chunk_write_fn
Performance optimization work on the rename detection continues.
* en/diffcore-rename:
merge-ort: call diffcore_rename() directly
gitdiffcore doc: mention new preliminary step for rename detection
diffcore-rename: guide inexact rename detection based on basenames
diffcore-rename: complete find_basename_matches()
diffcore-rename: compute basenames of source and dest candidates
t4001: add a test comparing basename similarity and content similarity
diffcore-rename: filter rename_src list when possible
diffcore-rename: no point trying to find a match better than exact
Preliminary changes to fsmonitor integration.
* jh/fsmonitor-prework:
fsmonitor: refactor initialization of fsmonitor_last_update token
fsmonitor: allow all entries for a folder to be invalidated
fsmonitor: log FSMN token when reading and writing the index
fsmonitor: log invocation of FSMonitor hook to trace2
read-cache: log the number of scanned files to trace2
read-cache: log the number of lstat calls to trace2

p7519: fix watchman watch-list test on Windows
p7519: do not rely on "xargs -d" in test
This reverts commit c85eec7fc3, as
it is a bit overzealous, we are in prerelease freeze, and we want
to have enough time to get this right and cook in 'next'.

"git push $there --delete ''" should have been diagnosed as an
error, but instead turned into a matching push, which has been
corrected.
* jc/push-delete-nothing:
push: do not turn --delete '' into a matching push
A handful of multi-word configuration variable names in
documentation that are spelled in all lowercase have been corrected
to use the more canonical camelCase.

Various fixes on "git add --chmod".
* mt/add-chmod-fixes:

add: mark --chmod error string for translation
add --chmod: don't update index when --dry-run is used
The code to implement "git merge-base --independent" was poorly
done and was kept from the very beginning of the feature.
* ds/merge-base-independent:
commit-reach: stale commits may prune generation further
commit-reach: use heuristic in remove_redundant()
commit-reach: move compare_commits_by_gen
commit-reach: use one walk in remove_redundant()
commit-reach: reduce requirements for remove_redundant()
"git rebase --[no-]fork-point" gained a configuration variable
rebase.forkPoint so that users do not have to keep specifying a
non-default setting.
* ah/rebase-no-fork-point-config:
rebase: add a config option for --no-fork-point
"git grep" has been tweaked to be limited to the sparse checkout
paths.
* mt/grep-sparse-checkout:
grep: honor sparse-checkout on working tree searches
"git difftool" learned "--skip-to=<path>" option to restart an
interrupted session from an arbitrary path.
* zh/difftool-skip-to:
difftool.c: learn a new way start at specified file
"git {diff,log} --{skip,rotate}-to=<path>" allows the user to
discard diff output for early paths or move them to the end of the
output.
* jc/diffcore-rotate:
diff: --{rotate,skip}-to=<path>
The error codepath around the "--temp/--prefix" feature of "git
checkout-index" has been improved.
* mt/checkout-index-corner-cases:
checkout-index: omit entries with no tempname from --temp output
write_entry(): fix misuses of `path` in error messages
Objects that lost references can be pruned away, even when they
have notes attached to it (and these notes will become dangling,
which in turn can be pruned with "git notes prune"). This has been
clarified in the documentation.
* mz/doc-notes-are-not-anchors:
docs: clarify that refs/notes/ do not keep the attached objects alive
Removal of GIT_TEST_GETTEXT_POISON continues.
* ab/detox-gettext-tests:
tests: remove most uses of test_i18ncmp
tests: remove last uses of C_LOCALE_OUTPUT
tests: remove most uses of C_LOCALE_OUTPUT

If `add` encounters an error while applying the --chmod changes, it
prints a message to stderr, but exits with a success code. This might
have been an oversight, as the command does exit with a non-zero code in
other situations where it cannot (or refuses to) update all of the
requested paths (e.g. when some of the given paths are ignored). So make
the exit behavior more consistent by also propagating --chmod errors to
the exit status.
Note: the test "all statuses changed in folder if . is given" uses paths
added by previous test cases, some of which might be symbolic links.
Because `git add --chmod` will now fail with such paths, this test would
depend on whether all the previous tests were executed, or only some
of them. Avoid that by running the test on a fresh repo with only
regular files.

This error message is intended for humans, so mark it for translation.
Also use error() instead of fprintf(stderr, ...), to make the
corresponding line a bit cleaner, and to display the "error:" prefix,
which helps classifying the nature/severity of the message.

When writing a commit-graph, a progress meter is shown which indicates
the number of pieces of data to write (one per commit in each chunk).
In 47410aa837 (commit-graph: use chunk-format write API, 2021-02-18),
the number of chunks became tracked by the new chunk-format API. But a
stray local variable was left behind from when write_commit_graph_file()
used to keep track of the same.
Since this was no longer updated after 47410aa837, the progress meter
appeared broken:
$ git commit-graph write --reachable
Expanding reachable commits in commit graph: 837569, done.
Writing out commit graph in 3 passes: 166% (4187845/2512707), done.
Drop the local variable and rely instead on the chunk-format API to tell
us the correct number of chunks.

When we added a syntax sugar "git push remote --delete <ref>" to
"git push" as a synonym to the canonical "git push remote :<ref>"
syntax at f517f1f2 (builtin-push: add --delete as syntactic sugar
for :foo, 2009-12-30), we weren't careful enough to make sure that
<ref> is not empty.
Blindly rewriting "--delete <ref>" to ":<ref>" means that an empty
string <ref> results in refspec ":", which is the syntax to ask for
"matching" push that does not delete anything.
Worse yet, if there were matching refs that can be fast-forwarded,
they would have been published prematurely, even if the user feels
that they are not ready yet to be pushed out, which would be a real
disaster.

We describe the more strict date formats accepted by GIT_COMMITTER_DATE,
etc, but the --date option also allows the looser approxidate formats,
as well. Unfortunately we don't have a good or complete reference for
this format, but let's at least mention that it _is_ looser, and give a
few examples.
If we ever write separate, more complete date-format documentation, we
should refer to it from here.

This adds yet another vimdiff/gvimdiff variant and presents conflicts as
a two-way diff between 'LOCAL' and 'REMOTE'. 'MERGED' is not opened
which deviates from the norm so usage text is echoed as a Vim message on
startup that instructs the user with how to proceed and how to abort.
Vimdiff is well-suited to two-way diffs so this is an option for a more
simple, more streamlined conflict resolution. For example: it is
difficult to communicate differences across more than two files using
only syntax highlighting; default vimdiff commands to get and put
changes between buffers do not need the user to manually specify
a source or destination buffer when only using two buffers.
Like other merge tools that directly compare 'LOCAL' with 'REMOTE', this
tool will benefit when paired with the new `mergetool.hideResolved`
setting.

The periodic maintenance tasks configured by `git maintenance start`
invoke `git for-each-repo` to run `git maintenance run` on each path
specified by the multi-value global configuration variable
`maintenance.repo`. Because `git for-each-repo` will likely be run
outside of the repositories which require periodic maintenance, it is
mandatory that the repository paths specified by `maintenance.repo` are
absolute.
Unfortunately, however, `git maintenance register` does nothing to
ensure that the paths it assigns to `maintenance.repo` are indeed
absolute, and may in fact -- especially in the case of a bare repository
-- assign a relative path to `maintenance.repo` instead. Fix this
problem by converting all paths to absolute before assigning them to
`maintenance.repo`.
While at it, also fix `git maintenance unregister` to convert paths to
absolute, as well, in order to ensure that it can correctly remove from
`maintenance.repo` a path assigned via `git maintenance register`.

next it calls compute_topological_levels() which can cause the slab to

clear_topo_level_slab() when we're done.
