What's cooking in git.git (Oct 2019, #01; Thu, 3)
--------------------------------------------------
 
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.
 
I've been offline for a week or so, and have been trying to process
the backlog, but I am sure there are still things to be picked up.
 
You can find the changes described here in the integration branches
of the repositories listed at
 
    http://git-blame.blogspot.com/p/git-public-repositories.html
 
--------------------------------------------------
[New Topics]
 
* ag/sequencer-todo-updates (2019-10-02) 5 commits
 - sequencer: directly call pick_commits() from complete_action()
 - rebase: fill `squash_onto' in get_replay_opts()
 - sequencer: move the code writing total_nr on the disk to a new function
 - sequencer: update `done_nr' when skipping commands in a todo list
 - sequencer: update `total_nr' when adding an item to a todo list
 
 Expecting a reroll.
 cf. <nycvar.QRO.7.76.6.1910021018360.46@tvgsbejvaqbjf.bet> to clarify log messages.
 there may be others.
 
 
* ah/cleanups (2019-10-03) 4 commits
 - git_mkstemps_mode(): replace magic numbers with computed value
 - wrapper: use a loop instead of repetitive statements
 - diffcore-break: use a goto instead of a redundant if statement
 - commit-graph: remove a duplicate assignment
 
 Miscellaneous code clean-ups.
 
 Will merge to 'next'.
 
 
* as/shallow-slab-use-fix (2019-10-02) 1 commit
 - shallow.c: don't free unallocated slabs
 
 Correct code that tried to reference all entries in a sparse array
 of pointers by mistake.
 
 Will merge to 'next'.
 
 
* js/fetch-jobs (2019-10-02) 1 commit
 - fetch: let --jobs=<n> parallelize --multiple, too
 
 "git fetch --jobs=<n>" allowed <n> parallel jobs when fetching
 submodules, but this did not apply to "git fetch --multiple" that
 fetches from multiple remote repositories.  It now does.
 
 Will merge to 'next'.
 
 
* js/mingw-spawn-with-spaces-in-path (2019-10-02) 1 commit
 - t0061: fix test for argv[0] with spaces (MINGW only)
 
 Test fix.
 
 Will merge to 'next'.
 
 
* gs/commit-graph-trace-with-cmd (2019-10-02) 1 commit
 - commit-graph: emit trace2 cmd_mode for each sub-command
 
 Dev support.
 
 Will merge to 'next'.
 
 
* js/trace2-fetch-push (2019-10-03) 2 commits
 - push: add trace2 instrumentation
 - fetch: add trace2 instrumentation
 
 Dev support.
 
 Will merge to 'next'.
 
 
* js/range-diff-noprefix (2019-10-03) 1 commit
 - range-diff: internally force `diff.noprefix=true`
 
 "git range-diff" segfaulted when diff.noprefix configuration was
 used, as it blindly expected the patch it internally generates to
 have the standard a/ and b/ prefixes.  The command now forces the
 internal patch to be built without any prefix, not to be affected
 by any end-user configuration.
 
 Will merge to 'next'.

 + t3206: abstract away hash size constants
 + t3201: abstract away SHA-1-specific constants
 
 Preparation for SHA-256 upgrade continues in the test department.
 
 
* bw/rebase-autostash-keep-current-branch (2019-09-07) 2 commits
  (merged to 'next' on 2019-09-18 at 6d8ed846ed)
 + builtin/rebase.c: Remove pointless message
 + builtin/rebase.c: make sure the active branch isn't moved when autostashing
 
 "git rebase --autostash <upstream> <branch>", when <branch> is
 different from the current branch, incorrectly moved the tip of the
 current branch, which has been corrected.
 
 
* dl/compat-cleanup (2019-09-05) 2 commits
  (merged to 'next' on 2019-09-09 at e33c896e16)

 (this branch is used by dl/cocci-everywhere.)
 
 Code cleanup.
 
 
* dl/complete-cherry-pick-revert-skip (2019-08-27) 3 commits
  (merged to 'next' on 2019-09-18 at 7dd173f824)
 + status: mention --skip for revert and cherry-pick
 + completion: add --skip for cherry-pick and revert
 + completion: merge options for cherry-pick and revert
 
 The command line completion support (in contrib/) learned about the
 "--skip" option of "git revert" and "git cherry-pick".
 
 
* dl/format-patch-doc-test-cleanup (2019-09-05) 13 commits
  (merged to 'next' on 2019-09-09 at b3022b4002)

 + t4014: drop unnecessary blank lines from test cases
 (this branch is used by dl/format-patch-cover-letter-subject.)
 
 The documentation and tests for "git format-patch" have been
 cleaned up.
 
 
* dl/rebase-i-keep-base (2019-08-27) 9 commits
  (merged to 'next' on 2019-09-18 at f94f486724)
 + rebase: teach rebase --keep-base
 + rebase tests: test linear branch topology
 + rebase: fast-forward --fork-point in more cases
 + rebase: fast-forward --onto in more cases
 + rebase: refactor can_fast_forward into goto tower
 + t3432: test for --no-ff's interaction with fast-forward
 + t3432: distinguish "noop-same" v.s. "work-same" in "same head" tests
 + t3432: test rebase fast-forward behavior
 + t3431: add rebase --fork-point tests
 
 "git rebase --keep-base <upstream>" tries to find the original base
 of the topic being rebased and rebase on top of that same base,
 which is useful when running the "git rebase -i" (and its limited
 variant "git rebase -x").
 
 The command also has learned to fast-forward in more cases where it
 can instead of replaying to recreate identical commits.
 
 
* dl/use-sq-from-test-lib (2019-09-06) 1 commit
  (merged to 'next' on 2019-09-09 at 9a6619ddab)

 Code cleanup.
 
 
* ds/commit-graph-on-fetch (2019-09-03) 1 commit

 graph after finishing.
 
 
* ds/include-exclude (2019-09-05) 5 commits
  (merged to 'next' on 2019-09-18 at 1a3655a089)
 + unpack-trees: rename 'is_excluded_from_list()'
 + treewide: rename 'exclude' methods to 'pattern'
 + treewide: rename 'EXCL_FLAG_' to 'PATTERN_FLAG_'
 + treewide: rename 'struct exclude_list' to 'struct pattern_list'
 + treewide: rename 'struct exclude' to 'struct path_pattern'
 
 The internal code originally invented for ".gitignore" processing
 got reshuffled and renamed to make it less tied to "excluding" and
 stress more that it is about "matching", as it has been reused for
 things like sparse checkout specification that want to check if a
 path is "included".
 
 
* dt/remote-helper-doc-re-lock-option (2019-08-30) 1 commit
  (merged to 'next' on 2019-09-09 at 970488992a)

 - grep: avoid leak of chartables in PCRE2
 - grep: make PCRE2 aware of custom allocator

* dl/format-patch-cover-letter-subject (2019-09-05) 1 commit
 - format-patch: learn --infer-cover-subject option
 
 "git format-patch --cover-letter" learned to optionally use the
 first paragraph (typically a single-liner) of branch.*.description
 as the subject of the cover letter.
 
 Reroll with a redesign with less emphasis on "subject" coming?
 
 
* jn/unknown-index-extensions (2018-11-21) 2 commits
 - index: offer advice for unknown index extensions

 header in the series of header fields has been moved down, which
 may help working around a suspected bug in GMail MSA, reported at
 <CAHk-=whP1stFZNAaJiMi5eZ9rj0MRt20Y_yHVczZPH+O01d+sA@mail.gmail.com>

 listing the protocol versions it is willing to talk, and the other
 side choosing from one of them.
 
 Expecting a reroll.

 Traditionally, we avoided threaded grep while searching in objects
 (as opposed to files in the working tree) as accesses to the object
 layer is not thread-safe.  This limitation is getting lifted.

 - Move git_sort(), a stable sort, into into libgit.a
 
 The rename detection logic sorts a list of rename source candidates
 by similarity to pick the best candidate, which means that a tie
 between sources with the same similarity is broken by the original
 location in the original canidate list (which is sorted by path).
 Force the sorting by similarity done with a stable sort, which is
 not promised by system supplied qsort(3), to ensure consistent
 results across platforms.
