What's cooking in git.git (May 2018, #01; Mon, 7)

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.

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


[New Topics]

* tb/test-apfs-utf8-normalization (2018-05-02) 1 commit
 - test: correct detection of UTF8_NFD_TO_NFC for APFS

 A test to see if the filesystem normalizes UTF-8 filename has been
 updated to check what we need to know in a more direct way, i.e. a
 path created in NFC form can be accessed with NFD form (or vice
 versa) to cope with APFS as well as HFS.

* ab/get-short-oid (2018-05-02) 12 commits
 - get_short_oid: document & warn if we ignore the type selector
 - config doc: document core.disambiguate
 - get_short_oid / peel_onion: ^{commit} should be commit, not committish
 - get_short_oid / peel_onion: ^{tree} should be tree, not treeish
 - get_short_oid: learn to disambiguate by ^{blob}
 - get_short_oid: learn to disambiguate by ^{tag}
 - get_short_oid: sort ambiguous objects by type, then SHA-1
 - sha1-name.c: move around the collect_ambiguous() function
 - cache.h: add comment explaining the order in object_type
 - git-p4: change "commitish" typo to "committish"
 - sha1-array.h: align function arguments

 Misc doc fixes.

 Will merge to 'next'.

* bc/format-patch-cover-no-attach (2018-05-02) 1 commit
 - format-patch: make cover letters always text/plain

 "git format-patch --cover --attach" created a broken MIME multipart
 message for the cover letter, which has been fixed by keeping the
 cover letter as plain text file.

 Will merge to 'next'.

* bp/test-drop-caches (2018-05-04) 1 commit
 - test-drop-caches: simplify delay loading of NtSetSystemInformation

 Code simplification.

 Will merge to 'next'.

* cc/perf-bisect (2018-05-06) 1 commit
 - perf/bisect_run_script: disable codespeed

 Performance test updates.

 Will merge to 'next'.

* cf/submodule-progress-dissociate (2018-05-04) 3 commits
 - submodule: add --dissociate option to add/update commands
 - submodule: add --progress option to add command
 - submodule: clean up subsititions in script

 "git submodule update" and "git submodule add" supported the
 "--reference" option to borrow objects from a neighbouring local
 repository like "git clone" does, but lacked the more recent
 invention "--dissociate".  Also "git submodule add" has been taught
 to take the "--progress" option.

 Is this ready for 'next'?  Should "git submodule -h" list the new
 options in its short help?

* dd/send-email-reedit (2018-05-06) 1 commit
 - git-send-email: allow re-editing of message

 "git send-email" can sometimes offer confirmation dialog "Send this
 email?" with choices 'Yes', 'No', 'Quit', and 'All'.  A new action
 'Edit' has been added to this dialog's choice.
 Waiting briefly for an ack or two.
 cf. <xmqq4ljlsahj.fsf@xxxxxxxxxxxxxxxxxxxxxxxxx>

* em/status-rename-config (2018-05-06) 1 commit
 - wt-status: use settings from git_diff_ui_config

 "git status" learned to pay attention to UI related diff
 configuration variables such as diff.renames.

 Will merge to 'next'.

* jm/cache-entry-from-mem-pool (2018-05-02) 5 commits
 - block alloc: add validations around cache_entry lifecyle
 - block alloc: allocate cache entries from mem_pool
 - mem-pool: fill out functionality
 - block alloc: add lifecycle APIs for cache_entry structs
 - read-cache: teach refresh_cache_entry() to take istate

 For a large tree, the index needs to hold many cache entries
 allocated on heap.  These cache entries are now allocated out of a
 dedicated memory pool to amortize malloc(3) overhead.

 Needs review.  
 Is the "caller always knows which pool an entry came from and calls
 the right kind of free" a feasible approach?

* js/branch-diff (2018-05-06) 18 commits

 - branch-diff: first rudimentary implementation
 - Add a new builtin: branch-diff
 - Add a function to solve least-cost assignment problems

 "git tbdiff" that lets us compare individual patches in two
 iterations of a topic has been rewritten and made into a built-in

 Expecting a reroll.
 cf. <nycvar.QRO.>

* js/sequencer-and-root-commits (2018-05-06) 6 commits
 - rebase --rebase-merges: root commits can be cousins, too
 - rebase --rebase-merges: a "merge" into a new root is a fast-forward
 - sequencer: allow introducing new root commits
 - rebase -i --root: let the sequencer handle even the initial part
 - sequencer: learn about the special "fake root commit" handling
 - sequencer: extract helper to update active_cache_tree
 (this branch uses js/rebase-recreate-merge.)

 The implementation of "git rebase -i --root" has been updaed to use
 the sequencer machinery more.

 Will merge to 'next'.

* js/use-bug-macro (2018-05-06) 4 commits
 - Convert remaining die*(BUG) messages
 - Replace all die("BUG: ...") calls by BUG() ones

 - Merge branch 'bw/protocol-v2' into jt/partial-clone-proto-v2
 (this branch uses bw/protocol-v2; is tangled with bw/server-options.)

 Transfer protocol v2 learned to support the partial clone.

 Will merge to 'next'.

* ma/doc-expand-tabs (2018-05-02) 1 commit
 - revisions.txt: expand tabs to spaces in diagram

 Fix one instance of asciidoctor's misformatting by expanding a tab
 into spaces in a literal block.

 Will discard.  This approach is less maintainable than the approach
 taken by bc/asciidoctor-tab-width topic.

* nd/completion-aliasfiletype-typofix (2018-05-06) 1 commit
 - completion: fix misspelled config key aliasesfiletype


 Will merge to 'next'.

* nd/doc-header (2018-05-02) 1 commit

 (this branch uses sb/object-store-replace and sb/oid-object-info.)

 The conversion to pass "the_repository" and then "a_repository"
 throughout the object access API continues.

* tb/grep-column (2018-05-06) 7 commits
 - contrib/git-jump/git-jump: jump to match column in addition to line
 - grep.c: add configuration variables to show matched option
 - builtin/grep.c: add '--column' option to 'git-grep(1)'
 - grep.c: display column number of first match
 - grep.[ch]: extend grep_opt to allow showing matched column
 - grep.c: expose matched column in match_line()
 - Documentation/config.txt: camel-case lineNumber for consistency

 "git grep" learned the "--column" option that gives not just the
 line number but the column number of the hit.

* bc/asciidoctor-tab-width (2018-05-07) 2 commits
 - Documentation: render revisions correctly under Asciidoctor
 - Documentation: use 8-space tabs with Asciidoctor

 Asciidoctor gives a reasonable imitation for AsciiDoc, but does not
 render illustration in a literal block correctly when indented with
 HT by default. The problem is fixed by forcing 8-space tabs.

 Will merge to 'next'.

* bc/mailmap-self (2018-05-07) 1 commit
 - mailmap: update brian m. carlson's email address

 Will merge to 'next'.

* pw/add-p-select (2018-03-16) 3 commits
 - add -p: optimize line selection for short hunks
 - add -p: allow line selection to be inverted
 - add -p: select individual hunk lines

 "git add -p" interactive interface learned to let users choose
 individual added/removed lines to be used in the operation, instead
 of accepting or rejecting a whole hunk.

 Expecting a reroll to reignite the discussion.
 cf. <9895c7b7-eac4-28c1-90c6-443acd1131b7@xxxxxxxxxxxx>

* jh/json-writer (2018-03-28) 1 commit
 - json_writer: new routines to create data in JSON format

 Preparatory code to later add json output for unspecified telemetry

 We do not add random code that does not have real users to our
 codebase, so let's have it wait until such a real code materializes
 before too long.

* hn/bisect-first-parent (2018-04-21) 1 commit
 - bisect: create 'bisect_flags' parameter in find_bisection()

 Preliminary code update to allow passing more flags down the
 bisection codepath in the future.

 We do not add random code that does not have real users to our
 codebase, so let's have it wait until such a real code materializes
 before too long.

* is/parsing-line-range (2018-04-27) 2 commits
 . log: prevent error if line range ends past end of file
 . blame: prevent error if range ends past end of file

 Parsing of -L[<N>][,[<M>]] parameters "git blame" and "git log"
 take has been tweaked.

 Seems to break a few tests.

* ld/p4-unshelve (2018-02-22) 1 commit
 - git-p4: add unshelve command

 "git p4" learned to "unshelve" shelved commit from P4.

 Will hold, perhaps drop and use format-change that uses a proper "diff".
 cf. <CAE5ih7_ooDMqVtTMoQ70s5XCkncr04HY0JkqSp1UmKQeG81oaA@xxxxxxxxxxxxxx>

 Code clean-up on fsmonitor integration, plus optional utilization
 of the fsmonitor data in diff-files.

 Waiting for an update.
 cf. <alpine.DEB.>

* mk/http-backend-content-length (2017-11-27) 4 commits
 - SQUASH???
 - t5560-http-backend-noserver.sh: add CONTENT_LENGTH cases
 - SQUASH???
 - http-backend: respect CONTENT_LENGTH as specified by rfc3875

 The http-backend (used for smart-http transport) used to slurp the
 whole input until EOF, without paying attention to CONTENT_LENGTH
 that is supplied in the environment and instead expecting the Web
 server to close the input stream.  This has been fixed.

 Expecting a reroll.
 Suggested fixes to be used when rerolling is queued, but I'd
 prefer _not_ squashing them myself.

 Also, it may be too complex solution for the problem.
 cf. <20171204171308.GA13332@xxxxxxxxxxxxxxxxxxxxx>

* mk/use-size-t-in-zlib (2017-08-10) 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".

 Needs resurrecting by making sure the fix is good and still applies
 (or adjusted to today's codebase).


* cc/perf-aggregate-unknown-option (2018-04-26) 1 commit
 - perf/aggregate: use Getopt::Long for option parsing

 Perf-test helper updates.

 - .gitattributes: add a diff driver for Python
 - .gitattributes: use the "perl" differ for Perl

 We learned that our source files with ".pl" and ".py" extensions
 are Perl and Python files respectively and changes to them are
 better viewed as such with appropriate diff drivers.

 Will merge to 'next'.

 The command line completion mechanism (in contrib/) learned to load
 custom completion file for "git $command" where $command is a
 custom "git-$command" that the end user has on the $PATH when using
 newer version of bash.

  (merged to 'next' on 2018-04-25 at 0367d52a4b)
 + worktree: accept -f as short for --force for removal

 "git worktree remove" learned that "-f" is a shorthand for
 "--force" option, just like for "git worktree add".

 Will merge to 'master'.

 Will merge to 'master'.

* js/ident-date-fix (2018-04-19) 1 commit
  (merged to 'next' on 2018-04-30 at d50ec2f4c1)
 + sequencer: reset the committer date before commits

 During a "rebase -i" session, the code could give older timestamp
 to commits created by later "pick" than an earlier "reword", which
 has been corrected.

 Will merge to 'master'.

* nd/submodule-status-fix (2018-04-19) 1 commit
  (merged to 'next' on 2018-04-30 at 34d1f9ca83)
 + submodule--helper: don't print null in 'submodule status'

 "git submodule status" did not check the symbolic revision name it
 computed for the submodule HEAD is not the NULL, and threw it at
 printf routines, which has been corrected.

 Will merge to 'master'.

* sa/send-email-dedup-some-headers (2018-04-19) 1 commit
  (merged to 'next' on 2018-04-30 at 2a1fd8217e)
 + send-email: avoid duplicate In-Reply-To/References

 When fed input that already has In-Reply-To: and/or References:
 headers and told to add the same information, "git send-email"
 added these headers separately, instead of appending to an existing
 one, which is a violation of the RFC.  This has been corrected.

 Will merge to 'master'.

* tg/demote-stash-save-in-completion (2018-04-20) 2 commits
  (merged to 'next' on 2018-04-30 at 93d0af5375)
 + completion: make stash -p and alias for stash push -p
 + completion: stop showing 'save' for stash by default

 The command line completion (in contrib/) has been taught that "git
 stash save" has been deprecated ("git stash push" is the preferred
 spelling in the new world) and does not offer it as a possible
 completion candidate when "git stash push" can be.

 - replace: "libify" create_graft() and callees
 - replace: avoid using die() to indicate a bug
 - commit: Let the callback of for_each_mergetag return on error
 - argv_array: offer to split a string by whitespace

 The functionality of "$GIT_DIR/info/grafts" has been superseded by
 the "refs/replace/" mechanism for some time now, but the internal
 code had support for it in many places, which has been cleaned up
 in order to drop support of the "grafts" mechanism.

 Will merge to 'next'.

* js/rebase-i-clean-msg-after-fixup-continue (2018-05-02) 4 commits

 - sequencer: always commit without editing when asked for
 - rebase -i: Handle "combination of <n> commits" with GETTEXT_POISON
 - rebase -i: demonstrate bugs with fixup!/squash! commit messages

 "git rebase -i" sometimes left intermediate "# This is a
 combination of N commits" message meant for the human consumption
 inside an editor in the final result in certain corner cases, which
 has been fixed.

 + parseopt: handle malformed --expire arguments more nicely
 + gc: do not upcase error message shown with die()

 silently failed when underlying "git prune --expire=nonsense"
 failed to parse its command line.  This has been corrected.

 Will merge to 'master'.

* ma/http-walker-no-partial (2018-04-24) 2 commits
  (merged to 'next' on 2018-04-30 at 4582c99ba8)
 + walker: drop fields of `struct walker` which are always 1
 + http-fetch: make `-a` standard behaviour

 "git http-fetch" (deprecated) had an optional and experimental
 "feature" to fetch only commits and/or trees, which nobody used.
 This has been removed.

 - directory rename detection: directory splitting testcases
 - directory rename detection: basic testcases
 (this branch is used by bp/merge-rename-config.)

 Rename detection logic in "diff" family that is used in "merge" has
 learned to guess when all of x/a, x/b and x/c have moved to z/a,
 z/b and z/c, it is likely that x/d added in the meantime would also
 want to move to z/d by taking the hint that the entire directory
 'x' moved to 'z'.  Incidentally, this avoids updating a file in the
 working tree after a (non-trivial) merge whose result matches what
 our side originally had.

 + git_config_set: do not use a state machine
 + config_set_store: rename some fields for consistency
 + config: avoid using the global variable `store`
 + config: introduce an optional event stream while parsing
 + t1300: `--unset-all` can leave an empty section behind (bug)
 + t1300: add a few more hairy examples of sections becoming empty
 + t1300: remove unreasonable expectation from TODO
 + t1300: avoid relying on a bug

 + git_config_set: fix off-by-two

 "git config --unset a.b", when "a.b" is the last variable in an
 otherwise empty section "a", left an empty section "a" behind, and
 worse yet, a subsequent "git config a.c value" did not reuse that
 empty shell and instead created a new one.  These have been
 (partially) corrected.

 Moving a submodule that itself has submodule in it with "git mv"
 forgot to make necessary adjustment to the nested sub-submodules;
 now the codepath learned to recurse into the submodules.

* tb/config-type (2018-04-19) 2 commits

 + builtin/config.c: support `--type=<type>` as preferred alias for `--<type>`
 + builtin/config.c: treat type specifiers singularly
 (this branch is used by tb/config-default.)

 The "git config" command uses separate options e.g. "--int",
 "--bool", etc. to specify what type the caller wants the value to
 be interpreted as.  A new "--type=<typename>" option has been
 introduced, which would make it cleaner to define new types.

 Will merge to 'master'.

* tb/config-default (2018-04-23) 3 commits

 + builtin/config: introduce `color` type specifier
 + config.c: introduce 'git_config_color' to parse ANSI colors
 + builtin/config: introduce `--default`
 (this branch uses tb/config-type.)

 "git config --get" learned the "--default" option, to help the
 calling script.  Building on top of the tb/config-type topic, the
 "git config" learns "--type=color" type.  Taken together, you can
 do things like "git config --get foo.color --default blue" and get
 the ANSI color sequence for the color given to foo.color variable,
 or "blue" if the variable does not exist.

 + t3200: unset core.logallrefupdates when testing reflog creation
 (this branch is used by jk/branch-l-1-removal and jk/branch-l-2-reincarnation.)

 The "-l" option in "git branch -l" is an unfortunate short-hand for
 "--create-reflog", but many users, both old and new, somehow expect
 it to be something else, perhaps "--list".  This step deprecates
 the short-hand and warns about the future removal of the it when it
 is used.

 - branch: make "-l" a synonym for "--list"

 "git gc" in a large repository takes a lot of time as it considers
 to repack all objects into one pack by default.  The command has
 been taught to pretend as if the largest existing packfile is
 marked with ".keep" so that it is left untouched while objects in
 other packs and loose ones are repacked.

 . Makefile: add Perl runtime prefix support
 . Makefile: generate Perl header from template file

 The Windows port was the first that allowed Git to be installed
 anywhere by having its components refer to each other with relative
 pathnames.  The recent dj/runtime-prefix topic extends the idea to
 other platforms, and its approach has been adopted back in the
 Windows port.

 Ejected, as the parent topic dj/runtime-prefix covers Windows now.

* bp/fsexcludes (2018-04-16) 2 commits
 . fsmonitor: switch to use new fsexcludes logic and remove unused untracked cache based logic
 . fsexcludes: add a programmatic way to exclude files from git's working directory traversal logic

 Can we have a few lines summary here, just like we have for other
 topic ;-) I personally take the overlong title of these commits as
 a sign that they can further be simplified and cleaned up by
 splitting, focusing the scope, etc.
