Subject: What's cooking in git.git (Jul 2016, #06; Tue, 19)

From: Junio C Hamano <[email-masked]>
Date: Tue, 19 Jul 2016 15:54:23 -0700

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

    http://git-blame.blogspot.com/p/git-public-repositories.html

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

* ew/autoconf-pthread (2016-07-18) 1 commit
  (merged to 'next' on 2016-07-19 at 146e249)
 + configure.ac: stronger test for pthread linkage

 Existing autoconf generated test for the need to link with pthread
 library did not check all the functions from pthread libraries;
 recent FreeBSD has some functions in libc but not others, and we
 mistakenly thought linking with libc is enough when it is not.

 Will merge to 'master'.

* ew/daemon-socket-keepalive (2016-07-18) 1 commit
  (merged to 'next' on 2016-07-19 at 0140849)
 + daemon: ignore ENOTSOCK from setsockopt

 Recent update to "git daemon" tries to enable the socket-level
 KEEPALIVE, but when it is spawned via inetd, the standard input
 file descriptor may not necessarily be connected to a socket.
 Suppress an ENOTSOCK error from setsockopt().

 Will merge to 'master'.

* jc/doc-diff-filter-exclude (2016-07-14) 1 commit
  (merged to 'next' on 2016-07-19 at 0c8aa92)
 + diff: document diff-filter exclusion

 Belated doc update for a feature added in v1.8.5.

 Will merge to 'master'.

* jk/push-scrub-url (2016-07-14) 1 commit
  (merged to 'next' on 2016-07-19 at 6ada3f1)
 + push: anonymize URL in status output

 "git fetch http://user:pass@host/repo..." scrubbed the userinfo
 part, but "git push" didn't.

 Will merge to 'master'.

* js/fsck-name-object (2016-07-18) 4 commits
  (merged to 'next' on 2016-07-19 at 6f39d2f)
 + fsck: optionally show more helpful info for broken links
 + fsck: give the error function a chance to see the fsck_options
 + fsck_walk(): optionally name objects on the go
 + fsck: refactor how to describe objects

 When "git fsck" reports a broken link (e.g. a tree object contains
 a blob that does not exist), both containing object and the object
 that is referred to were reported with their 40-hex object names.
 The command learned the "--name-objects" option to show the path to
 the containing object from existing refs (e.g. "HEAD~24^2:file.txt").

 Will merge to 'master'.

* mh/blame-worktree (2016-07-18) 2 commits
  (merged to 'next' on 2016-07-19 at 4c39534)
 + t/t8003-blame-corner-cases.sh: Use here documents
 + blame: allow to blame paths freshly added to the index

 "git blame file" allowed the lineage of lines in the uncommitted,
 unadded contents of "file" to be inspected, but it refused when
 "file" did not appear in the current commit.  When "file" was
 created by renaming an existing file (but the change has not been
 committed), this restriction was unnecessarily tight.

 Will merge to 'master'.

* jt/fetch-large-handshake-window-on-http (2016-07-19) 1 commit
 - fetch-pack: grow stateless RPC windows exponentially

 "git fetch" exchanges batched have/ack messages between the sender
 and the receiver, initially doubling every time and then falling
 back to use the maximum window size.  The "smart http" transport,
 being an half-duplex protocol, outgrows the preset limit too
 quickly and becomes inefficient when interacting with a large
 repository.  The internal mechanism learned to grow the window size
 more aggressively when working with the "smart http" transport.

 Will merge to 'next'.

* ew/svn-authorsprog-doc (2016-07-19) 1 commit
 - git-svn: document svn.authorsProg in config

 Belated doc update.

 Perhaps I will get a copy of this directly from Eric together with
 other updates to git-svn, in which case this needs to be scrapped.

* rs/use-strbuf-addbuf (2016-07-19) 1 commit
  (merged to 'next' on 2016-07-19 at 679f992)
 + use strbuf_addbuf() for appending a strbuf to another

 Code cleanup.

 Will merge to 'master'.

* rs/submodule-config-code-cleanup (2016-07-19) 1 commit
  (merged to 'next' on 2016-07-19 at 59dbd58)
 + submodule-config: use explicit empty string instead of strbuf in config_from()

 Code cleanup.

 Will merge to 'master'.

[Graduated to "master"]

* ah/unpack-trees-advice-messages (2016-06-27) 1 commit
  (merged to 'next' on 2016-07-06 at 4254fc2)
 + unpack-trees: fix English grammar in do-this-before-that messages

 Grammofix.

* ak/lazy-prereq-mktemp (2016-07-06) 1 commit
  (merged to 'next' on 2016-07-11 at 66a9384)
 + t7610: test for mktemp before test execution

 A test that unconditionally used "mktemp" learned that the command
 is not necessarily available everywhere.

* bc/cocci (2016-06-28) 11 commits
  (merged to 'next' on 2016-07-06 at f2e8e2a)
 + diff: convert prep_temp_blob() to struct object_id
 + merge-recursive: convert merge_recursive_generic() to object_id
 + merge-recursive: convert leaf functions to use struct object_id
 + merge-recursive: convert struct merge_file_info to object_id
 + merge-recursive: convert struct stage_data to use object_id
 + diff: rename struct diff_filespec's sha1_valid member
 + diff: convert struct diff_filespec to struct object_id
 + coccinelle: apply object_id Coccinelle transformations
 + coccinelle: convert hashcpy() with null_sha1 to hashclr()
 + contrib/coccinelle: add basic Coccinelle transforms
 + hex: add oid_to_hex_r()
 (this branch is used by js/am-3-merge-recursive-direct.)

 Conversion from unsigned char sha1[20] to struct object_id
 continues.

* dg/subtree-rebase-test (2016-06-28) 1 commit
  (merged to 'next' on 2016-07-06 at 4dec1ad)
 + contrib/subtree: Add a test for subtree rebase that loses commits

 Add a test to specify the desired behaviour that currently is not
 available in "git rebase -Xsubtree=...".

* dk/blame-move-no-reason-for-1-line-context (2016-05-29) 1 commit
  (merged to 'next' on 2016-07-06 at 087490c)
 + blame: require 0 context lines while finding moved lines with -M

 "git blame -M" missed a single line that was moved within the file.

* ew/gc-auto-pack-limit-fix (2016-06-27) 1 commit
  (merged to 'next' on 2016-07-06 at aa023d3)
 + gc: fix off-by-one error with gc.autoPackLimit

 "gc.autoPackLimit" when set to 1 should not trigger a repacking
 when there is only one pack, but the code counted poorly and did
 so.

* jk/big-and-future-archive-tar (2016-07-01) 5 commits
  (merged to 'next' on 2016-07-06 at 89f3835)
 + archive-tar: drop return value
 + archive-tar: write extended headers for far-future mtime
 + archive-tar: write extended headers for file sizes >= 8GB
 + t5000: test tar files that overflow ustar headers
 + t9300: factor out portable "head -c" replacement

 "git archive" learned to handle files that are larger than 8GB and
 commits far in the future than expressible by the traditional US-TAR
 format.

* jk/common-main (2016-07-06) 1 commit
  (merged to 'next' on 2016-07-11 at 1c2228a)
 + Merge branch 'jk/common-main-2.8' into jk/common-main
 (this branch uses jk/common-main-2.8.)

 There are certain house-keeping tasks that need to be performed at
 the very beginning of any Git program, and programs that are not
 built-in commands had to do them exactly the same way as "git"
 potty does.  It was easy to make mistakes in one-off standalone
 programs (like test helpers).  A common "main()" function that
 calls cmd_main() of individual program has been introduced to
 make it harder to make mistakes.

* jk/common-main-2.8 (2016-07-06) 6 commits
 + mingw: declare main()'s argv as const
 + common-main: call git_setup_gettext()
 + common-main: call restore_sigpipe_to_default()
 + common-main: call sanitize_stdfds()
 + common-main: call git_extract_argv0_path()
 + add an extra level of indirection to main()
 (this branch is used by jk/common-main.)

* jk/printf-format (2016-07-08) 3 commits
  (merged to 'next' on 2016-07-11 at 731eafb)
 + commit.c: remove print_commit_list()
 + avoid using sha1_to_hex output as printf format
 + walker: let walker_say take arbitrary formats

 Code clean-up to avoid using a variable string that compilers may
 feel untrustable as printf-style format given to write_file()
 helper function.

* jk/test-match-signal (2016-07-06) 4 commits
  (merged to 'next' on 2016-07-11 at 54e1462)
 + t/lib-git-daemon: use test_match_signal
 + test_must_fail: use test_match_signal
 + t0005: use test_match_signal as appropriate
 + tests: factor portable signal check out of t0005

 The test framework learned a new helper test_match_signal to
 check an exit code from getting killed by an expected signal.

* jk/write-file (2016-07-08) 9 commits
  (merged to 'next' on 2016-07-11 at f51b449)
 + branch: use write_file_buf instead of write_file
 + use write_file_buf where applicable
 + write_file: add format attribute
 + write_file: add pointer+len variant
 + write_file: use xopen
 + write_file: drop "gently" form
 + branch: use non-gentle write_file for branch description
 + am: ignore return value of write_file()
 + config: fix bogus fd check when setting up default config

 General code clean-up around a helper function to write a
 single-liner to a file.

 While it is textually independent, jk/printf-format needs to be
 merged before this one.

* js/am-call-theirs-theirs-in-fallback-3way (2016-07-08) 1 commit
  (merged to 'next' on 2016-07-11 at abae4bc)
 + am: counteract gender bias
 (this branch is used by js/am-3-merge-recursive-direct.)

 One part of "git am" had an oddball helper function that called
 stuff from outside "his" as opposed to calling what we have "ours",
 which was not gender-neutral and also inconsistent with the rest of
 the system where outside stuff is usuall called "theirs" in
 contrast to "ours".

* js/log-to-diffopt-file (2016-07-11) 12 commits
  (merged to 'next' on 2016-07-13 at d7a0af7)
 + mingw: fix the shortlog --output=<file> test
  (merged to 'next' on 2016-07-06 at 39e7a5f)
 + diff: do not color output when --color=auto and --output=<file> is given
 + t4211: ensure that log respects --output=<file>
 + shortlog: respect the --output=<file> setting
 + format-patch: use stdout directly
 + format-patch: avoid freopen()
 + format-patch: explicitly switch off color when writing to files
 + shortlog: support outputting to streams other than stdout
 + graph: respect the diffopt.file setting
 + line-log: respect diffopt's configured output file stream
 + log-tree: respect diffopt's configured output file stream
 + log: prepare log/log-tree to reuse the diffopt.close_file attribute

 The commands in the "log/diff" family have had an FILE* pointer in the
 data structure they pass around for a long time, but some codepaths
 used to always write to the standard output.  As a preparatory step
 to make "git format-patch" available to the internal callers, these
 codepaths have been updated to consistently write into that FILE*
 instead.

* js/sign-empty-commit-fix (2016-06-29) 1 commit
  (merged to 'next' on 2016-07-06 at 448da1b)
 + commit -S: avoid invalid pointer with empty message

 "git commit --amend --allow-empty-message -S" for a commit without
 any message body could have misidentified where the header of the
 commit object ends.

* js/t3404-grammo-fix (2016-06-29) 1 commit
  (merged to 'next' on 2016-07-06 at 4378654)
 + t3404: fix a grammo (commands are ran -> commands are run)

 Grammofix.

* lf/recv-sideband-cleanup (2016-07-06) 2 commits
  (merged to 'next' on 2016-07-06 at d527bcb)
 + sideband.c: small optimization of strbuf usage
 + sideband.c: refactor recv_sideband()

 Code simplification.

* ls/p4-tmp-refs (2016-07-08) 1 commit
  (merged to 'next' on 2016-07-11 at 4af2d93)
 + git-p4: place temporary refs used for branch import under refs/git-p4-tmp

 "git p4" used a location outside $GIT_DIR/refs/ to place its
 temporary branches, which has been moved to refs/git-p4-tmp/.

* mm/doc-tt (2016-06-28) 7 commits
  (merged to 'next' on 2016-07-06 at a8c74bd)
 + doc: typeset HEAD and variants as literal
 + CodingGuidelines: formatting HEAD in documentation
 + doc: typeset long options with argument as literal
 + doc: typeset '--' as literal
 + doc: typeset long command-line options as literal
 + doc: typeset short command-line options as literal
 + Documentation/git-mv.txt: fix whitespace indentation

 More mark-up updates to typeset strings that are expected to
 literally typed by the end user in fixed-width font.

* nd/connect-ssh-command-config (2016-07-06) 1 commit
  (merged to 'next' on 2016-07-06 at 6eac316)
 + connect: read $GIT_SSH_COMMAND from config file

 A new configuration variable core.sshCommand has been added to
 specify what value for GIT_SSH_COMMAND to use per repository.

* nd/doc-new-command (2016-06-27) 1 commit
  (merged to 'next' on 2016-07-06 at 1404b64)
 + new-command.txt: correct the command description file

 Typofix in a doc.

* nd/fetch-ref-summary (2016-07-06) 5 commits
  (merged to 'next' on 2016-07-11 at 379df9f)
 + fetch: reduce duplicate in ref update status lines with placeholder
 + fetch: align all "remote -> local" output
 + fetch: change flag code for displaying tag update and deleted ref
 + fetch: refactor ref update status formatting code
 + git-fetch.txt: document fetch output

 Improve the look of the way "git fetch" reports what happened to
 each ref that was fetched.

* nd/icase (2016-07-01) 12 commits
  (merged to 'next' on 2016-07-11 at a00d080)
 + grep.c: reuse "icase" variable
 + diffcore-pickaxe: support case insensitive match on non-ascii
 + diffcore-pickaxe: Add regcomp_or_die()
 + grep/pcre: support utf-8
 + gettext: add is_utf8_locale()
 + grep/pcre: prepare locale-dependent tables for icase matching
 + grep: rewrite an if/else condition to avoid duplicate expression
 + grep/icase: avoid kwsset when -F is specified
 + grep/icase: avoid kwsset on literal non-ascii strings
 + test-regex: expose full regcomp() to the command line
 + test-regex: isolate the bug test code
 + grep: break down an "if" stmt in preparation for next changes

 "git grep -i" has been taught to fold case in non-ascii locales
 correctly.

* nd/ita-cleanup (2016-07-01) 3 commits
  (merged to 'next' on 2016-07-06 at f15aeba)
 + grep: fix grepping for "intent to add" files
 + t7810-grep.sh: fix a whitespace inconsistency
 + t7810-grep.sh: fix duplicated test name

 Git does not know what the contents in the index should be for a
 path added with "git add -N" yet, so "git grep --cached" should not
 show hits (or show lack of hits, with -L) in such a path, but that
 logic does not apply to "git grep", i.e. searching in the working
 tree files.  But we did so by mistake, which has been corrected.

* ps/rebase-i-auto-unstash-upon-abort (2016-06-29) 1 commit
  (merged to 'next' on 2016-07-06 at 0fdcedb)
 + rebase -i: restore autostash on abort

 "git rebase -i --autostash" did not restore the auto-stashed change
 when the operation was aborted.

* rs/help-c-source-with-gitattributes (2016-07-07) 1 commit
  (merged to 'next' on 2016-07-11 at b90b7d0)
 + .gitattributes: set file type for C files

 The .c/.h sources are marked as such in our .gitattributes file so
 that "git diff -W" and friends would work better.

* sb/submodule-parallel-fetch (2016-07-11) 3 commits
  (merged to 'next' on 2016-07-11 at 4983ded)
 + hoist out handle_nonblock function for xread and xwrite
  (merged to 'next' on 2016-07-06 at de5fd35)
 + xwrite: poll on non-blocking FDs
 + xread: retry after poll on EAGAIN/EWOULDBLOCK

 Fix recently introduced codepaths that are involved in parallel
 submodule operations, which gave up on reading too early, and
 could have wasted CPU while attempting to write under a corner
 case condition.

* va/i18n-even-more (2016-07-01) 39 commits
  (merged to 'next' on 2016-07-01 at fa5e50e3)

 (this branch is used by js/am-3-merge-recursive-direct.)

 More markings of messages for i18n, with updates to various tests
 to pass GETTEXT_POISON tests.

 One patch from the original submission dropped due to conflicts
 with jk/upload-pack-hook, which is still in flux.

 Needs review.

 - bisect: write about `bisect next` in documentation

 The internal algorithm used in "git bisect" to find the next commit
 to check has been optimized greatly.

 Expecting a reroll.

 - diffcore-rename: allow easier debugging
 - diffcore-rename.c: add locate_rename_src()
 - diffcore-break: allow debugging

 "git diff -B -M" produced incorrect patch when the postimage of a
 completely rewritten file is similar to the preimage of a removed
 file; such a resulting file must not be expressed as a rename from
 other place.

 The fix in this patch is broken, unfortunately.
 Will discard.

 "git am -3" calls "git merge-recursive" when it needs to fall back
 to a three-way merge; this call has been turned into an internal
 subroutine call instead of spawning a separate subprocess.

 Will be rerolled, unless Joey says something about the interaction
 with the other topic.

 + pack-objects: do not truncate result in-pack object size on 32-bit systems
 + index-pack: correct "offset" type in unpack_entry_data()
 + index-pack: report correct bad object offsets even if they are large
 + index-pack: correct "len" type in unpack_data()
 + sha1_file.c: use type off_t* for object_info->disk_sizep
 + pack-objects: pass length to check_pack_crc() without truncation

 "git pack-objects" and "git index-pack" mostly operate with off_t
 when talking about the offset of objects in a packfile, but there
 were a handful of places that used "unsigned long" to hold that
 value, leading to an unintended truncation.

 - log: decorate HEAD -> branch with the same color for arrow and HEAD

 An entry "git log --decorate" for the tip of the current branch is
 shown as "HEAD -> name" (where "name" is the name of the branch);
 paint the arrow in the same color as "HEAD", not in the color for
 commits.

 Comments?  Personally I find it more-or-less "Meh".

 The use of strbuf in "git rm" to build filename to remove was a bit

* jh/clean-smudge-annex (2016-07-12) 9 commits

 - better recovery from failure of smudgeToFile filter
 - warn on unusable smudgeToFile/cleanFromFile config
 - use smudgeToFile in git checkout etc
 - use cleanFromFile in git add

 - clarify %f documentation
 - Merge branch 'cc/apply-am' into jh/clean-smudge-annex
 (this branch is used by js/am-3-merge-recursive-direct; uses cc/apply-am.)

 The interface to "clean/smudge" filters require Git to feed the
 whole contents via pipe, which is suboptimal for some applications.
 "cleanFromFile/smudgeToFile" commands are the moral equilvalents
 for these filters but they interact with the files on the
 filesystem directly.

 Will need to wait for all the topics this depends on graduate to 'master'.

 + notes-merge: use O_EXCL to avoid overwriting existing files

 "git notes merge" had a code to see if a path exists (and fails if
 it does) and then open the path for writing (when it doesn't).
 Replace it with open with O_EXCL.

 Will merge to 'master'.

* rw/make-needs-librt (2016-07-11) 2 commits
  (merged to 'next' on 2016-07-13 at 7fafd37)
 + config.mak.uname: define NEEDS_LIBRT under Linux, for now
 + Makefile: add NEEDS_LIBRT to optionally link with librt

 Makefile assumed that -lrt is always available on platforms that
 want to use clock_gettime() and CLOCK_MONOTONIC, which is not a
 case for recent Mac OS X.  The necessary symbols are often found in
 libc on many modern systems and having -lrt on the command line, as
 long as the library exists, had no effect, but when the platform
 removes librt.a that is a different matter--having -lrt will break
 the linkage.

 This change could be seen as a regression for those who do need to
 specify -lrt, as they now specifically ask for NEEDS_LIBRT when
 building. Hopefully they are in the minority these days.

 -   pull: fast-forward "pull --rebase=true"

 "git pull --rebase", when there is no new commits on our side since
 we forked from the upstream, should be able to fast-forward without
 invoking "git rebase", but it didn't.

 Needs a real log message and a few tests.

* po/range-doc (2016-07-01) 3 commits
 - doc: give headings for the two and three dot notations
 - doc: show the actual left, right, and boundary marks

 Clarify various ways to specify the "revision ranges" in the

 Will hold.

 There is another one that tries to clarify r1..r2 excludes r1
 itself, which is not queued here waiting for the conclusion of a
 review discussion.  Otherwise looked good.

* ex/deprecate-empty-pathspec-as-match-all (2016-06-22) 1 commit
  (merged to 'next' on 2016-07-13 at d9ca7fb)
 + pathspec: warn on empty strings as pathspec

 An empty string used as a pathspec element has always meant
 'everything matches', but it is too easy to write a script that
 finds a path to remove in $path and run 'git rm "$paht"', which
 ends up removing everything.  Start warning about this use of an
 empty string used for 'everything matches' and ask users to use a
 more explicit '.' for that instead.

 The hope is that existing users will not mind this change, and
 eventually the warning can be turned into a hard error, upgrading
 the deprecation into removal of this (mis)feature.

 Will hold to see if people scream.

 (this branch uses mh/ref-iterators and mh/split-under-lock; is tangled with mh/update-ref-errors.)

 The ref-store abstraction was introduced to the refs API so that we
 can plug in different backends to store references.

* jc/blame-reverse (2016-06-14) 2 commits
 - blame: dwim "blame --reverse OLD" as "blame --reverse OLD.."
 - blame: improve diagnosis for "--reverse NEW"

 It is a common mistake to say "git blame --reverse OLD path",
 expecting that the command line is dwimmed as if asking how lines
 in path in an old revision OLD have survived up to the current
 commit.

 Any supporters?  Otherwise will drop.

 - upload-pack: move shallow deepen code out of receive_needs()
 - transport-helper.c: refactor set_helper_option()
 - remote-curl.c: convert fetch_git() to use argv_array

 The existing "git fetch --depth=<n>" option was hard to use
 correctly when making the history of an existing shallow clone
 deeper.  A new option, "--deepen=<n>", has been added to make this
 easier to use.  "git clone" also learned "--shallow-since=<date>"
 and "--shallow-exclude=<tag>" options to make it easier to specify
 "I am interested only in the recent N months worth of history" and
 "Give me only the history since that version".

 Needs review.

 Rerolled.  What this topic attempts to achieve is worthwhile, I
 would think.

 The attributes API has been updated so that it can later be
 optimized using the knowledge of which attributes are queried.

 I wanted to polish this topic further to make the attribute
 subsystem thread-ready, but because other topics depend on this
 topic and they do not (yet) need it to be thread-ready, let's merge
 this early part together with the dependent topics to 'next', and
 back-burner the threading enhancement to another day.

 go?

* sb/pathspec-label (2016-06-03) 6 commits
 - pathspec: disable preload-index when attribute pathspec magic is in use
 - pathspec: allow escaped query values

 - pathspec: move long magic parsing out of prefix_pathspec
 - Documentation: fix a typo
 (this branch is used by sb/submodule-default-paths; uses jc/attr; is tangled with jc/attr-more.)

 The pathspec mechanism learned ":(attr:X)$pattern" pathspec magic
 to limit paths that match $pattern further by attribute settings.
 The preload-index mechanism is disabled when the new pathspec magic
 is in use (at least for now), because the attribute subsystem is
 not thread-ready.

 - ref-filter: introduce format_ref_array_item()
 - ref-filter: move get_head_description() from branch.c
 - ref-filter: modify "%(objectname:short)" to take length
 - ref-filter: implement %(if:equals=<string>) and %(if:notequals=<string>)
 - ref-filter: include reference to 'used_atom' within 'atom_value'
 - ref-filter: implement %(if), %(then), and %(else) atoms

 The code to list branches in "git branch" has been consolidated
 with the more generic ref-filter API.

 Rerolled.
 This also really needs review.

 A new "index-helper" daemon has been introduced to give newly
 spawned Git process a quicker access to the data in the index, and
 optionally interface with the watchman daemon to further reduce the
 refresh cost.

 Not quite ready yet, it seems.

* jc/bundle (2016-03-03) 6 commits
 - index-pack: --clone-bundle option
 - Merge branch 'jc/index-pack' into jc/bundle
 - bundle v3: the beginning
 - bundle: keep a copy of bundle file name in the in-core bundle header
 - bundle: plug resource leak
 - bundle doc: 'verify' is not about verifying the bundle

 The beginning of "split bundle", which could be one of the
 ingredients to allow "git clone" traffic off of the core server
 network to CDN.

 While I think it would make it easier for people to experiment and
 build on if the topic is merged to 'next', I am at the same time a
 bit reluctant to merge an unproven new topic that introduces a new
 file format, which we may end up having to support til the end of
 time.  Comments?

* jc/merge-drop-old-syntax (2015-04-29) 1 commit
 - merge: drop 'git merge <message> HEAD <commit>' syntax

 Stop supporting "git merge <message> HEAD <commit>" syntax that has
 been deprecated since October 2007, and issues a deprecation
 warning message since v2.5.0.

 It has been reported that git-gui still uses the deprecated syntax,
 which needs to be fixed before this final step can proceed.
