Here are the topics that have been cooking.  Commits prefixed with
'-' are only in '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.

2.27-rc0 has been tagged.  I haven't seen much discussion on
proposed topics for 2.26.3, so haven't merged anything (yet), but
now the 'master' and 'next' front would be more quiescent, efforts
focused on regressions, perhaps people can help pick the topics for
the maintenance track.

You can find the changes described here in the integration branches
of the repositories listed at

[Graduated to "master"]

* ao/p4-d-f-conflict-recover (2020-05-10) 1 commit
  (merged to 'next' on 2020-05-11 at a83a2f6178)
 + git-p4: recover from inconsistent perforce history

 "git p4" learned to recover from a (broken) state where a directory
 and a file are recorded at the same path in the Perforce repository
 the same way as their clients do.

* cw/bisect-replay-with-dos (2020-05-08) 1 commit
  (merged to 'next' on 2020-05-11 at 2eb0edf56d)
 + bisect: allow CRLF line endings in "git bisect replay" input

 "git bisect replay" had trouble with input files when they used
 CRLF line ending, which has been corrected.

  (merged to 'next' on 2020-05-11 at 046d49d455)
 + completion: offer '--(no-)patch' among 'git log' options

 + bloom: parse commit before computing filters
 + test-bloom: fix usage typo
 + bloom: fix whitespace around tab length

 Code cleanup and typofixes.
 This is an early part of ds/line-log-on-bloom that has been cooking
 in 'next'.

* es/bugreport-with-hooks (2020-05-07) 1 commit
  (merged to 'next' on 2020-05-11 at 2dd5d90a34)
 + bugreport: collect list of populated hooks
 (this branch is used by es/bugreport-shell.)

  (merged to 'next' on 2020-05-13 at a127540258)

 Teach codepaths that show progress meter to also use the
 start_progress() and the stop_progress() calls as a "region" to be
 traced.

  (merged to 'next' on 2020-05-11 at d18f0d930e)

  (merged to 'next' on 2020-05-11 at 3cdf7f7ece)
 + rebase --autosquash: fix a potential segfault

 "rebase -i" segfaulted when rearranging a sequence that has a
 fix-up that applies another fix-up (which may or may not be a
 fix-up of yet another step).

* jt/t5500-unflake (2020-05-06) 1 commit
  (merged to 'next' on 2020-05-13 at 11450265ec)
 + t5500: count objects through stderr, not trace

 Test fix for a topic already in 'master' and meant for 'maint'.

* rs/fsck-duplicate-names-in-trees (2020-05-11) 1 commit
  (merged to 'next' on 2020-05-11 at f603ca2528)
 + fsck: report non-consecutive duplicate names in trees

 "git fsck" ensures that the paths recorded in tree objects are
 sorted and without duplicates, but it failed to notice a case where
 a blob is followed by entries that sort before a tree with the same
 name.  This has been corrected.

* sn/midx-repack-with-config (2020-05-10) 2 commits
  (merged to 'next' on 2020-05-11 at d73f8f51d6)

[New Topics]

 function we no longer use.

* cb/t4210-illseq-auto-detect (2020-05-14) 1 commit
 - t4210: detect REG_ILLSEQ dynamically

 As FreeBSD is not the only platform whose regexp library needs
 REG_ILLSEQ prerequisite, add a logic to detect the prerequisite
 automatically.

* en/merge-rename-rename-worktree-fix (2020-05-14) 1 commit
 - merge-recursive: fix rename/rename(1to2) for working tree with a binary

 When a binary file gets renamed and then merged with a minor
 change, the copy on the working tree while conflict resolution
 sometimes got "their" version and not "ours".

 Will merge to 'next'.

--------------------------------------------------
[Stalled]

* mk/use-size-t-in-zlib (2018-10-15) 1 commit
 - zlib.c: use size_t for size

 The wrapper to call into zlib followed our long tradition to use
 "unsigned long" for sizes of regions in memory, which have been
 updated to use "size_t".

--------------------------------------------------
[Cooking]

* bk/p4-prepare-p4-only-fix (2020-05-12) 1 commit
 - git-p4.py: fix --prepare-p4-only error with multiple commits

 The "--prepare-p4-only" option is supposed to stop after replaying
 one changeset, but kept going (by mistake?)

 Needs review by some p4 folks.

 "git grep" has been tweaked to be limited to the sparse checkout
 paths.

 Expecting a reroll.

* js/ci-sdk-download-fix (2020-05-12) 1 commit
 - ci: avoid pounding on the poor ci-artifacts container

 Instead of downloading Windows SDK for CI jobs for windows builds
 from an external site (wingit.blob.core.windows.net), use the one
 created in the windows-build job, to work around quota issues at
 the external site.

 Will merge to 'next'.
 Hopefully this can go away once cmake-for-windows-build topic lands?

 Needs review.

* dr/push-remoteref-fix (2020-04-23) 1 commit
 - remote.c: fix handling of %(push:remoteref)

 The "%(push:remoteref)" placeholder in the "--format=" argument of
 "git format-patch" (and friends) only showed what got explicitly
 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).

 Expecting a reroll.
 cf. <20200416152145.wp2zeibxmuyas6y6@feanor>

* pw/rebase-i-more-options (2020-04-29) 5 commits

 "git receive-pack" that accepts requests by "git push" learned to
 outsource most of the ref updates to the new "proc-receive" hook.

 Needs review.

* hn/refs-cleanup (2020-05-11) 6 commits
 - reftable: define version 2 of the spec to accomodate SHA256
 - reftable: clarify how empty tables should be written
 - reftable: file format documentation
 - refs: document how ref_iterator_advance_fn should handle symrefs
 - t: use update-ref and show-ref to reading/writing refs
 - refs.h: clarify reflog iteration order
 (this branch is used by hn/reftable.)

 Preliminary clean-ups around refs API, plus file format
 specification documentation for the reftable backend.

 I splitted these out of the hn/reftable topic, hoping that these
 should be easier to polish and merge quickly than the rest of the
 series.

* hn/reftable (2020-05-11) 7 commits
 - Add some reftable testing infrastructure
 - vcxproj: adjust for the reftable changes
 - Reftable support for git-core
 - Add reftable library

 - Write pseudorefs through ref backends.
 (this branch uses hn/refs-cleanup.)

 A new refs backend "reftable" to replace the traditional
 combination of packed-refs files and one-file-per-ref loose refs
 has been implemented and integrated for improved performance and
 atomicity.

 Needs review.

* js/ci-skip-on-github-workflow (2020-05-02) 1 commit
 . ci: respect the [skip ci] convention in our GitHub workflow "CI/PR"

 Allow contributors to mark a branch/push that it does not have to
 be built via GitHub actions, in a way similar to how Travis lets
 them mark the commits with an embedded "[skip ci]" string.

 Superseded by dd/ci-only-on-selective-branches topic.

* dd/ci-only-on-selective-branches (2020-05-05) 2 commits
 - CI: limit GitHub Actions to designated branches
 - SubmittingPatches: advertise GitHub Actions CI

 Instead of always building all branches of all forks of our project
 at GitHub via GitHub Actions, only build when branches with known
 and specific names are updated, and also a pull request.
