  To: git

Here are the topics that have been cooking.  Commits prefixed with '-' are
only in 'seen' (formerly 'pu'---proposed updates) while commits prefixed
with '+' are in 'next'.  The ones marked with '.' do not appear in any of
the integration branches, but I am still holding onto them.

The number of topics merged for the next release since Git 2.29 has 
just passed 100 after the 8th batch of them have graduated.
I expect the rest of the week would be slower than usual, due to US
being holiday.

Copies of the source code to Git live in many repositories, and the
following is a list of the ones I push into.  Some repositories have
only a subset of branches.

With maint, master, next, seen, todo:


With all the integration branches and topics broken out:

Even though the preformatted documentation in HTML and man format
are not sources, they are published in these repositories for
convenience (replace "htmldocs" with "manpages" for the manual


Release tarballs are available at:

[Graduated to 'master']

 + Use new HASHMAP_INIT macro to simplify hashmap initialization
 + strmap: take advantage of FLEXPTR_ALLOC_STR when relevant
 + strmap: enable allocations to come from a mem_pool
 + strmap: add a strset sub-type
 + strmap: split create_entry() out of strmap_put()

 (this branch is used by en/merge-ort-impl.)

 A specialization of hashmap that uses a string as key has been
 introduced.  Hopefully it will see wider use over time.

* fc/bash-completion-alias-of-alias (2020-11-17) 3 commits
  (merged to 'next' on 2020-11-18 at 4241203041)

  (merged to 'next' on 2020-11-10 at 75f1f2b8a8)
 + completion: bash: check for alias loop
 + completion: bash: support recursive aliases

 The command line completion script (in contrib/) learned to expand
 commands that are alias of alias.

* jc/ci-github-set-env (2020-11-17) 1 commit
  (merged to 'next' on 2020-11-19 at 00ff5e06ac)

 Another CI adjustment.

* jc/format-patch-name-max (2020-11-09) 1 commit
  (merged to 'next' on 2020-11-11 at 17e19bb17a)
 + format-patch: make output filename configurable

 The maximum length of output filenames "git format-patch" creates
 has become configurable (used to be capped at 64).

* jk/4gb-idx (2020-11-16) 5 commits
  (merged to 'next' on 2020-11-18 at 2f99b73bda)
 + packfile: detect overflow in .idx file size checks

  (merged to 'next' on 2020-11-12 at 3b21625881)
 + t7800: simplify difftool test
  (merged to 'next' on 2020-11-09 at 6d89b9602d)
 + diff: allow passing NULL to diff_free_filespec_data()
 (this branch is used by js/default-branch-name-tests-final-stretch.)

 Running "git diff" while allowing external diff in a state with
 unmerged paths used to segfault, which has been corrected.

* jk/rev-parse-end-of-options (2020-11-10) 3 commits
  (merged to 'next' on 2020-11-11 at 2d517d1608)
 + rev-parse: handle --end-of-options
 + rev-parse: put all options under the "-" check
 + rev-parse: don't accept options after dashdash

 "git rev-parse" learned the "--end-of-options" to help scripts to
 safely take a parameter that is supposed to be a revision, e.g.
 "git rev-parse --verify -q --end-of-options $rev".

* jx/t5411-flake-fix (2020-11-11) 3 commits
  (merged to 'next' on 2020-11-18 at badb1fefe5)
 + receive-pack: use default version 0 for proc-receive

 The exchange between receive-pack and proc-receive hook did not
 carefully check for errors.

  (merged to 'next' on 2020-11-18 at 7cf396ee81)

 We can further update it to lose the hand-maintained function name
 from the message, but that can be done separately.

  (merged to 'next' on 2020-11-12 at aff20da3a2)
 + mergetool: avoid letting `list_tool_variants` break user-defined setups

  (merged to 'next' on 2020-11-18 at bdd3b21b7c)
 + submodules: fix of regression on fetching of non-init subsub-repo

 "git fetch" did not work correctly with nested submodules where the
 innermost submodule that is not of interest got updated in the
 upstream, which has been corrected.

* rs/archive-plug-leak-refname (2020-11-16) 1 commit
  (merged to 'next' on 2020-11-19 at 270ba7b8be)

* sg/bisect-approximately-halfway (2020-11-12) 1 commit
  (merged to 'next' on 2020-11-18 at b13026a0f3)
 + bisect: loosen halfway() check for a large number of commits

 "git bisect start/next" in a large span of history spends a lot of
 time trying to come up with exactly the half-way point; this can be
 optimized by stopping when we see a commit that is close enough to
 the half-way point.

* sg/t5310-jgit-wants-sha1 (2020-11-16) 1 commit
  (merged to 'next' on 2020-11-19 at 72fb4e7155)

 Since jgit does not yet work with SHA-256 repositories, mark the
 tests that uses it not to run unless we are testing with ShA-1

 + t7415: rename to expand scope
 + fsck_tree(): wrap some long lines
 + fsck_tree(): fix shadowed variable

 Originally merged to 'next' on 2020-10-23

 "git fsck" and the corresponding check done during the transport
 learned to ensure that in-tree files like `.gitignore` and
 `.gitattributes` are not symbolic links.

 It seems that there are real projects with .gitignore recorded as
 symlinks, which may need to loosen the fsck setting.  Do we need to
 introduce a class that is separate from symlinked .gitmodules that
 probably is with potential consequences that is more/less grave?

 The "%(push:remoteref)" placeholder in the "--format=" argument of

 configured, not what ref at the receiving end would be updated when
 "git push" was used, as it ignored the default behaviour (e.g. update
 the same ref as the source).

 - diff: do not show submodule with untracked files as "-dirty"

 "git diff" showed a submodule working tree with untracked cruft as
 "Submodule commit <objectname>-dirty", but a natural expectation is
 that the "-dirty" indicator would align with "git describe --dirty",
 which does not consider having untracked files in the working tree
 as source of dirtiness.  The inconsistency has been fixed.

Yep, this needs to be shuffled around. I know that Stolee and Jonathan
Tan are discussing some of the patches, too.

So, half of me is holding off while they discuss, to see if there is
anything that falls out and needs picking up. The other half of me is
busy preparing GitHub's MIDX bitmaps patches for upstream, and hasn't
had the time ;-).

I'll likely send a new version of that series after the US holiday when
I'm back in the office next week.

Sorry for the delay :-/.
