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.

The road to the upcoming 2.20 turned out to be a bit rockier as we
had a couple of subcommands with larger importance (rebase and
rebase-i) reimplemented, together with some new and exciting
commands (like range-diff and its integration into format-patch),
each with a few loose ends we needed to tie until the last minute.
I've let -rc1 and -rc2 slip for a few days to make sure we get
closer to a stable point, and I am hoping that a few topics that are
at the bottom of master..pu chain with today's pushout merged to the
'master' branch, I should be able to cut a 2.20-rc2 that is in a
reasonable shape.

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

--------------------------------------------------
[New Topics]

* gh/diff-raw-has-no-ellipses (2018-11-26) 1 commit
  (merged to 'next' on 2018-11-29 at 24a7536f15)
 + doc: update diff-format.txt for removed ellipses in --raw

 "git diff --raw" lost ellipses to adjust the output columns for
 some time now, but the documentation still showed them.

 Will cook in 'next'.


* mk/http-backend-kill-children-before-exit (2018-11-26) 1 commit
  (merged to 'next' on 2018-11-29 at bf2d45062f)
 + http-backend: enable cleaning up forked upload/receive-pack on exit

 The http-backend CGI process did not correctly clean up the child
 processes it spawns to run upload-pack etc. when it dies itself,
 which has been corrected.

 Will cook in 'next'.


* ab/replace-graft-with-replace-advice (2018-11-29) 1 commit
  (merged to 'next' on 2018-11-30 at c5d658e075)
 + advice: don't pointlessly suggest --convert-graft-file

 The advice message to tell the user to migrate an existing graft
 file to the replace system when a graft file was read was shown
 even when "git replace --convert-graft-file" command, which is the
 way the message suggests to use, was running, which made little
 sense.

 Will merge to 'master'.


* ma/reset-doc-rendering-fix (2018-11-29) 2 commits
  (merged to 'next' on 2018-11-30 at be718c19e2)
 + git-reset.txt: render literal examples as monospace
 + git-reset.txt: render tables correctly under Asciidoctor

 Doc updates.

 Will merge to 'master'.


* sg/daemon-test-signal-fix (2018-11-27) 1 commit
  (merged to 'next' on 2018-11-30 at b3f7fdf727)
 + t/lib-git-daemon: fix signal checking

 Test fix.

 Will merge to 'master'.


* tb/log-G-binary (2018-11-29) 1 commit
 - log -G: ignore binary files

 "git log -G<regex>" looked for a hunk in the "git log -p" patch
 output that contained a string that matches the given pattern.
 Optimize this code to ignore binary files, which by default will
 not show any hunk that would match any pattern (unless textconv or
 the --text option is in effect, that is).

 Expecting an update to the tests.


* jc/format-patch-range-diff-fix (2018-11-30) 1 commit
  (merged to 'next' on 2018-11-30 at 26290b1ec1)
 + format-patch: do not let its diff-options affect --range-diff

 "git format-patch --range-diff" by mistake passed the diff options
 used to generate the primary output of the command to the
 range-diff machinery, which caused the range-diff in the cover
 letter to include fairly useless "--stat" output.  This has been
 corrected by forcing a non-customizable default formatting options
 on the range-diff machinery when driven by format-patch.

 Will merge to 'master'.


* js/rebase-reflog-action-fix (2018-11-30) 1 commit
  (merged to 'next' on 2018-11-30 at 93fd2fb920)
 + rebase: fix GIT_REFLOG_ACTION regression

 "git rebase" reimplemented recently in C accidentally changed the
 way reflog entries are recorded (earlier "rebase -i" identified the
 entries it leaves with "rebase -i", but the new version always
 marks them with "rebase").  This has been corrected.

 Will merge to 'master'.


* js/rebase-stat-unrelated-fix (2018-11-30) 1 commit
  (merged to 'next' on 2018-11-30 at a9faaff8c1)
 + rebase --stat: fix when rebasing to an unrelated history

 "git rebase --stat" to transplant a piece of history onto a totally
 unrelated history were not working before and silently showed wrong
 result.  With the recent reimplementation in C, it started to instead
 die with an error message, as the original logic was not prepared
 to cope with this case.  This has now been fixed.

 Will merge to 'master'.

--------------------------------------------------
[Graduated to "master"]

* cc/delta-islands (2018-11-21) 3 commits
  (merged to 'next' on 2018-11-21 at 3bac399f83)
 + pack-objects: fix off-by-one in delta-island tree-depth computation
 + pack-objects: zero-initialize tree_depth/layer arrays
 + pack-objects: fix tree_depth and layer invariants

 A few issues in the implementation of "delta-islands" feature has
 been corrected.


* cc/shared-index-permbits (2018-11-19) 1 commit
  (merged to 'next' on 2018-11-19 at 79df716844)
 + read-cache: make the split index obey umask settings

 The way .git/index and .git/sharedindex* files were initially
 created gave these files different perm bits until they were
 adjusted for shared repository settings.  This was made consistent.


* jk/t5562-perl-path-fix (2018-11-24) 1 commit
  (merged to 'next' on 2018-11-24 at 2d8dca3544)
 + t5562: fix perl path

 Hotfix for test breakage on platforms whose Perl is not at
 /usr/bin/perl


* jn/eoie-ieot (2018-11-21) 3 commits
  (merged to 'next' on 2018-11-21 at 9eb98a38f0)
 + index: make index.threads=true enable ieot and eoie
 + ieot: default to not writing IEOT section
 + eoie: default to not writing EOIE section
 (this branch is used by jn/unknown-index-extensions.)

 As the warning message shown by existing versions of Git for
 unknown index extensions is a bit too alarming, two new extensions
 are held back and not written by default for the upcoming release.


* js/builtin-rebase-perf-fix-err-fix (2018-11-21) 1 commit
  (merged to 'next' on 2018-11-21 at 9c351cfc4a)
 + rebase: warn about the correct tree's OID

 The object name of the tree reported in a recently added error
 message was wrong, which has been corrected.


* js/rebase-am-options-fix (2018-11-21) 1 commit
  (merged to 'next' on 2018-11-21 at 4da85e17c2)
 + legacy-rebase: backport -C<n> and --whitespace=<option> checks

 Recently, built-in "rebase" tightened the error checking for a few
 options that are passed to underlying "am", but we forgot to make
 the matching change to the scripted version, which has been
 corrected.


* nd/clone-case-smashing-warning (2018-11-21) 1 commit
  (merged to 'next' on 2018-11-21 at 68bc7959f8)
 + clone: fix colliding file detection on APFS

 Recently added check for case smashing filesystems did not
 correctly utilize the cached stat information, leading to false
 breakage detected by our test suite, which has been corrected.


* nd/per-worktree-ref-iteration (2018-11-26) 1 commit
  (merged to 'next' on 2018-11-26 at b7c39e5946)
 + files-backend.c: fix build error on Solaris

 Build fix.


* tb/clone-case-smashing-warning-test (2018-11-24) 1 commit
  (merged to 'next' on 2018-11-24 at 37f0d3b920)
 + t5601-99: Enable colliding file detection for MINGW

 The code recently added to "git clone" to see if the platform's
 filesystem is adequate to check out and use the project code
 correctly (e.g. a case smashing filesystem cannot be used for a
 project with two files whose paths are different only in case) was
 meant to help Windows users, but the test for it was not enabled
 for that platform, which has been corrected.


* tz/build-tech-midx-doc (2018-11-21) 1 commit
  (merged to 'next' on 2018-11-21 at 15dd462db0)
 + Documentation: build technical/multi-pack-index

 A documentation page that is referred to by other pages was not
 built by mistake, which has been corrected.

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

* lt/date-human (2018-07-09) 1 commit
 - Add 'human' date format

 A new date format "--date=human" that morphs its output depending
 on how far the time is from the current time has been introduced.
 "--date=auto" can be used to use this new format when the output is
 goint to the pager or to the terminal and otherwise the default
 format.

[Cooking]

* dl/merge-cleanup-scissors-fix (2018-11-21) 2 commits
  (merged to 'next' on 2018-11-21 at 217be06acb)
 + merge: add scissors line on merge conflict
 + t7600: clean up 'merge --squash c3 with c7' test

 The list of conflicted paths shown in the editor while concluding a
 conflicted merge was shown above the scissors line when the
 clean-up mode is set to "scissors", even though it was commented
 out just like the list of updated paths and other information to
 help the user explain the merge better.

 Will cook in 'next'.


* aw/pretty-trailers (2018-11-19) 5 commits
 - pretty: add support for separator option in %(trailers)
 - strbuf: separate callback for strbuf_expand:ing literals
 - pretty: add support for "valueonly" option in %(trailers)
 - pretty: allow showing specific trailers
 - pretty: single return path in %(trailers) handling

 The %(trailers) formatter in "git log --format=..."  now allows to
 optionally pick trailers selectively by keyword, show only values,
 etc.


* nd/attr-pathspec-in-tree-walk (2018-11-19) 5 commits
 - tree-walk: support :(attr) matching
 - dir.c: move, rename and export match_attrs()
 - pathspec.h: clean up "extern" in function declarations
 - tree-walk.c: make tree_entry_interesting() take an index
 - tree.c: make read_tree*() take 'struct repository *'

 The traversal over tree objects has learned to honor
 ":(attr:label)" pathspec match, which has been implemented only for
 enumerating paths on the filesystem.


* ab/commit-graph-progress-fix (2018-11-20) 1 commit
 - commit-graph: split up close_reachable() progress output


* sg/test-BUG (2018-11-20) 1 commit
  (merged to 'next' on 2018-11-21 at bb81013952)
 + tests: send "bug in the test script" errors to the script's stderr

 test framework has been updated to make a bug in the test script
 (as opposed to bugs in Git that are discovered by running the
 tests) stand out more prominently.

 Will cook in 'next'.


* sg/test-cmp-rev (2018-11-20) 1 commit
  (merged to 'next' on 2018-11-21 at 5d65cb2a76)
 + test-lib-functions: make 'test_cmp_rev' more informative on failure

 Test framework update.

 Will cook in 'next'.


* ss/msvc-strcasecmp (2018-11-20) 1 commit
  (merged to 'next' on 2018-11-21 at 9e45649e6e)
 + msvc: directly use MS version (_stricmp) of strcasecmp

 MSVC update.

 Will cook in 'next'.


* jn/unknown-index-extensions (2018-11-21) 2 commits
 - index: offer advice for unknown index extensions
 - index: do not warn about unrecognized extensions

 A bit too alarming warning given when unknown index extensions
 exist is getting revamped.

 Expecting a reroll.


* ab/push-example-in-doc (2018-11-14) 1 commit
  (merged to 'next' on 2018-11-18 at 8fd935a19c)
 + push: change needlessly ambiguous example in error

 An error message that sugggests how to give correct arguments to
 "git push" has been updated.

 Will cook in 'next'.


* en/fast-export-import (2018-11-17) 11 commits
  (merged to 'next' on 2018-11-18 at 87bbbffc95)
 + fast-export: add a --show-original-ids option to show original names
 + fast-import: remove unmaintained duplicate documentation
 + fast-export: add --reference-excluded-parents option
 + fast-export: ensure we export requested refs
 + fast-export: when using paths, avoid corrupt stream with non-existent mark
 + fast-export: move commit rewriting logic into a function for reuse
 + fast-export: avoid dying when filtering by paths and old tags exist
 + fast-export: use value from correct enum
 + git-fast-export.txt: clarify misleading documentation about rev-list args
 + git-fast-import.txt: fix documentation for --quiet option
 + fast-export: convert sha1 to oid

 Small fixes and features for fast-export and fast-import, mostly on
 the fast-export side.

 Will cook in 'next'.


* nd/checkout-dwim-fix (2018-11-14) 1 commit
  (merged to 'next' on 2018-11-18 at 3d714e7719)
 + checkout: disambiguate dwim tracking branches and local files

 "git checkout frotz" (without any double-dash) avoids ambiguity by
 making sure 'frotz' cannot be interpreted as a revision and as a
 path at the same time.  This safety has been updated to check also
 a unique remote-tracking branch 'frotz' in a remote, when dwimming
 to create a local branch 'frotz' out of a remote-tracking branch
 'frotz' from a remote.

 Will cook in 'next'.


* nd/checkout-noisy (2018-11-20) 2 commits
 - t0027: squelch checkout path run outside test_expect_* block
 - checkout: print something when checking out paths

 "git checkout [<tree-ish>] path..." learned to report the number of
 paths that have been checked out of the index or the tree-ish,
 which gives it the same degree of noisy-ness as the case in which
 the command checks out a branch.


* sg/clone-initial-fetch-configuration (2018-11-16) 3 commits
  (merged to 'next' on 2018-11-18 at cae0f3985b)
 + Documentation/clone: document ignored configuration variables
 + clone: respect additional configured fetch refspecs during initial fetch
 + clone: use a more appropriate variable name for the default refspec

 Refspecs configured with "git -c var=val clone" did not propagate
 to the resulting repository, which has been corrected.

 Will cook in 'next'.


* en/rebase-merge-on-sequencer (2018-11-08) 2 commits
 - rebase: implement --merge via git-rebase--interactive
 - git-rebase, sequencer: extend --quiet option for the interactive machinery

 "git rebase --merge" as been reimplemented by reusing the internal
 machinery used for "git rebase -i".


* fc/http-version (2018-11-09) 1 commit
  (merged to 'next' on 2018-11-18 at 42f5155095)
 + http: add support selecting http version

 The "http.version" configuration variable can be used with recent
 enough cURL library to force the version of HTTP used to talk when
 fetching and pushing.

 Will cook in 'next'.


* dl/remote-save-to-push (2018-11-13) 1 commit
 - remote: add --save-to-push option to git remote set-url

 "git remote set-url" learned a new option that moves existing value
 of the URL field to pushURL field of the remote before replacing
 the URL field with a new value.


* jk/loose-object-cache (2018-11-24) 10 commits
  (merged to 'next' on 2018-11-24 at 5f4f22707d)
 + odb_load_loose_cache: fix strbuf leak
  (merged to 'next' on 2018-11-18 at 276691a21b)
 + fetch-pack: drop custom loose object cache
 + sha1-file: use loose object cache for quick existence check
 + object-store: provide helpers for loose_objects_cache
 + sha1-file: use an object_directory for the main object dir
 + handle alternates paths the same as the main object dir
 + sha1_file_name(): overwrite buffer instead of appending
 + rename "alternate_object_database" to "object_directory"
 + submodule--helper: prefer strip_suffix() to ends_with()
 + fsck: do not reuse child_process structs

 Code clean-up with optimization for the codepath that checks
 (non-)existence of loose objects.

 Will cook in 'next'.


* js/protocol-advertise-multi (2018-11-17) 1 commit
 - protocol: advertise multiple supported versions

 The transport layer has been updated so that the protocol version
 used can be negotiated between the parties, by the initiator
 listing the protocol versions it is willing to talk, and the other
 side choosing from one of them.


* js/smart-http-detect-remote-error (2018-11-17) 3 commits
  (merged to 'next' on 2018-11-18 at 5c6edfcb85)
 + remote-curl: die on server-side errors
 + remote-curl: tighten "version 2" check for smart-http
 + remote-curl: refactor smart-http discovery

 Some errors from the other side coming over smart HTTP transport
 were not noticed, which has been corrected.

 Will cook in 'next'.


* nb/branch-show-other-worktrees-head (2018-11-12) 2 commits
 - branch: mark and colorize a branch differently if it is checked out in a linked worktree
 - ref-filter: add worktree atom

 "git branch --list" learned to show branches that are checked out
 in other worktrees connected to the same repository prefixed with
 '+', similar to the way the currently checked out branch is shown
 with '*' in front.

 Expecting a reroll.


* nd/the-index (2018-11-12) 22 commits
  (merged to 'next' on 2018-11-18 at 73d1d8594e)

* ab/push-dwim-dst (2018-11-14) 7 commits
  (merged to 'next' on 2018-11-18 at 36567023be)
 + push doc: document the DWYM behavior pushing to unqualified <dst>
 + push: test that <src> doesn't DWYM if <dst> is unqualified
 + push: add an advice on unqualified <dst> push
 + push: move unqualified refname error into a function
 + push: improve the error shown on unqualified <dst> push
 + i18n: remote.c: mark error(...) messages for translation
 + remote.c: add braces in anticipation of a follow-up change

 "git push $there $src:$dst" rejects when $dst is not a fully
 qualified refname and not clear what the end user meant.  The
 codepath has been taught to give a clearer error message, and also
 guess where the push should go by taking the type of the pushed
 object into account (e.g. a tag object would want to go under
 refs/tags/).

* md/list-lazy-objects-fix (2018-10-29) 1 commit
 - list-objects.c: don't segfault for missing cmdline objects

 "git rev-list --exclude-promissor-objects" had to take an object
 that does not exist locally (and is lazily available) from the
 command line without barfing, but the code dereferenced NULL.

 That sympotom may be worth addressing, but I think the "fix" is
 overly broad and is wrong.  Giving a missing object should be
 diagnosed as an error, not swept under the rug silently.

 command is excempt from the requirement.

 Prepare to run test suite on Azure DevOps.

 Ejected out of 'pu', as doing so seems to help other topics get
 tested at TravisCI.

 https://travis-ci.org/git/git/builds/452713184 is a sample of a
 build whose tests on 4 hang (with this series in).  Ejecting it
 gave us https://travis-ci.org/git/git/builds/452778963 which still
 shows breakages from other topics not yet in 'next', but at least
 the tests do not stall.

 . sequencer: refactor transform_todos() to work on a todo_list
 . sequencer: make the todo_list structure public
 . sequencer: changes in parse_insn_buffer()

 The scripted version of "git rebase -i" wrote and rewrote the todo
 list many times during a single step of its operation, and the
 recent C-rewrite made a faithful conversion of the logic to C.  The
 implementation has been updated to carry necessary information
 around in-core to avoid rewriting the same file over and over
 unnecessarily.

 With too many topics in-flight that touch sequencer and rebaser,
 this need to wait giving precedence to other topics that fix bugs.

 individual added/removed lines to be used in the operation, instead
 of accepting or rejecting a whole hunk.

 The original implementation of "git archive --remote" more or less
 bypassed the transport layer and did not work over http(s).  The
 version 2 of the protocol is defined to allow going over http(s) as
 well as Git native transport.
