What's cooking in git.git (Jan 2015, #02; Mon, 12)
--------------------------------------------------

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 "preview" release candidate 2.3-rc0 has been tagged.  With the
slowness from the end-of-year holiday, this cycle turns out to be a
relatively lean one as I predicted (just 200 changes since 2.2, as
opposed to ~500 changes in an normal cycle), but that is fine.  From
time to time it is OK to have a release that does not add many new
things but just fixes niggles here and there.

A new maintenance release 2.2.2 is also out, which backports many
fixes that were not in 2.2.1 that have been used on 'master' for the
past few weeks.

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

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

* bb/update-unicode-table (2014-12-22) 5 commits
  (merged to 'next' on 2014-12-23 at b4ce669)
 + update_unicode.sh: delete the command group
 + update_unicode.sh: make the output structure visible
 + update_unicode.sh: shorten uniset invocation path
 + update_unicode.sh: set UNICODE_DIR only once
 + update_unicode.sh: simplify output capture

 Simplify the procedure to generate unicode table.


* bc/fetch-thin-less-aggressive-in-normal-repository (2014-12-29) 3 commits
  (merged to 'next' on 2015-01-07 at 60f9ada)
 + pack-objects: use --objects-edge-aggressive for shallow repos
 + rev-list: add an option to mark fewer edges as uninteresting
 + Documentation: add missing article in rev-list-options.txt

 Earlier we made "rev-list --object-edge" more aggressively list the
 objects at the edge commits, in order to reduce number of objects
 fetched into a shallow repository, but the change affected cases
 other than "fetching into a shallow repository" and made it
 unusably slow (e.g. fetching into a normal repository should not
 have to suffer the overhead from extra processing).  Limit it to a
 more specific case by introducing --objects-edge-aggressive, a new
 option to rev-list.


* br/imap-send-verbosity (2014-11-05) 1 commit
  (merged to 'next' on 2014-12-15 at 504af0b)
 + imap-send: use parse options API to determine verbosity
 (this branch is used by br/imap-send-via-libcurl and km/imap-send-libcurl-options.)

 "git imap-send" learned to take "-v" (verbose) and "-q" (quiet)
 command line options.


* br/imap-send-via-libcurl (2014-11-10) 1 commit
  (merged to 'next' on 2014-12-15 at 90db637)
 + git-imap-send: use libcurl for implementation
 (this branch is used by km/imap-send-libcurl-options; uses br/imap-send-verbosity.)

 Newer libCurl knows how to talk IMAP; "git imap-send" has been
 updated to use this instead of a hand-rolled OpenSSL calls.


* bw/maint-0090-awk-tweak (2014-12-23) 1 commit
  (merged to 'next' on 2014-12-29 at 9301c36)
 + t0090: tweak awk statement for Solaris /usr/xpg4/bin/awk


* cc/bisect-rev-parsing (2014-12-29) 2 commits
  (merged to 'next' on 2015-01-07 at 7b76eed)
 + bisect: add test to check that revs are properly parsed
 + bisect: parse revs before passing them to check_expected_revs()

 The logic in "git bisect bad HEAD" etc. to avoid forcing the test
 of the common ancestor of bad and good commits was broken.


* es/checkout-index-temp (2014-12-29) 5 commits
  (merged to 'next' on 2015-01-07 at d45c06d)
 + checkout-index: fix --temp relative path mangling
 + t2004: demonstrate broken relative path printing
 + t2004: standardize file naming in symlink test
 + t2004: drop unnecessary write-tree/read-tree
 + t2004: modernize style

 "git checkout-index --temp=$target $path" did not work correctly
 for paths outside the current subdirectory in the project.


* es/squelch-openssl-warnings-on-macosx (2014-12-18) 1 commit
  (merged to 'next' on 2014-12-23 at e88cf6a)
 + git-compat-util: suppress unavoidable Apple-specific deprecation warnings

 Squelch useless compiler warnings on Mac OS X.


* jc/checkout-local-track-report (2014-10-14) 1 commit
  (merged to 'next' on 2014-12-15 at e91a7df)
 + checkout: report upstream correctly even with loosely defined branch.*.merge

 The report from "git checkout" on a branch that builds on another
 local branch by setting its branch.*.merge to branch name (not a
 full refname) incorrectly said that the upstream is gone.


* jc/clone-borrow (2014-10-15) 1 commit
  (merged to 'next' on 2014-12-15 at 08fdf77)
 + clone: --dissociate option to mark that reference is only temporary

 Allow "git clone --reference" to be used more safely.


* jc/diff-b-m (2014-10-23) 1 commit
  (merged to 'next' on 2014-12-15 at 59c6636)
 + diff -B -M: fix output for "copy and then rewrite" case

 Fix long-standing bug in "diff -B -M" output.


* jc/merge-bases (2014-10-30) 2 commits
  (merged to 'next' on 2014-12-15 at cac279e)
 + get_merge_bases(): always clean-up object flags
 + bisect: clean flags after checking merge bases

 The get_merge_bases*() API was easy to misuse by careless
 copy&paste coders, leaving object flags tainted in the commits that
 needed to be traversed.


* jc/strbuf-add-lines-avoid-sp-ht-sequence (2014-10-27) 1 commit
  (merged to 'next' on 2014-12-15 at b499889)
 + strbuf_add_commented_lines(): avoid SP-HT sequence in commented lines

 The commented output used to blindly add a SP before the payload
 line, resulting in "# \t<indented text>\n" when the payload began
 with a HT.  Instead, produce "#\t<indented text>\n".


* jh/pre-push-sample-no-custom-ifs (2014-12-22) 1 commit
  (merged to 'next' on 2014-12-29 at c516021)
 + pre-push.sample: remove unnecessary and misleading IFS=' '

 The sample pre-push hook used customized IFS=' ' for no good reason.


* jk/add-i-read-error (2014-12-15) 1 commit
  (merged to 'next' on 2014-12-23 at 9b76001)
 + add--interactive: leave main loop on read error

 "git add -i" did not notice when the interactive command input
 stream went away and kept asking.


* jk/approxidate-avoid-y-d-m-over-future-dates (2014-11-13) 2 commits
  (merged to 'next' on 2014-12-15 at 397e986)
 + approxidate: allow ISO-like dates far in the future
 + pass TIME_DATE_NOW to approxidate future-check

 Traditionally we tried to avoid interpreting date strings given by
 the user as future dates, e.g. GIT_COMMITTER_DATE=2014-12-10 when
 used early November 2014 was taken as "October 12, 2014" because it
 is likely that a date in the future, December 10, is a mistake.

 This heuristics has been loosened to allow people to express future
 dates (most notably, --until=<date> may want to be far in the
 future) and we no longer tiebreak by future-ness of the date when

 (1) ISO-like format is used, and
 (2) the string can make sense interpreted as both y-m-d and y-d-m.

 Git may still have to use the heuristics to tiebreak between dd/mm/yy
 and mm/dd/yy, though.


* lh/send-email-hide-x-mailer (2014-12-15) 2 commits
  (merged to 'next' on 2014-12-23 at fc16c68)
 + test/send-email: --[no-]xmailer tests
 + send-email: add --[no-]xmailer option

 "git send-email" normally identifies itself via X-Mailer: header
 in the message it sends out.  A new command line flag allows the
 header to be squelched.


* nd/lockfile-absolute (2014-11-03) 1 commit
  (merged to 'next' on 2014-12-15 at 34db9af)
 + lockfile.c: store absolute path

 The lockfile API can get confused which file to clean up when the
 process moved the $cwd after creating a lockfile.


* pd/completion-filenames-fix (2014-12-15) 1 commit
  (merged to 'next' on 2014-12-23 at e2b10ab)
 + Update documentation occurrences of filename .sh

 The top-of-the-file instruction for completion scripts (in contrib/)
 did not name the files correctly.


* rd/send-email-2047-fix (2014-12-15) 2 commits
  (merged to 'next' on 2014-12-23 at 2b101ce)
 + send-email: handle adjacent RFC 2047-encoded words properly
 + send-email: align RFC 2047 decoding more closely with the spec

 "git send-email" did not handle RFC 2047 encoded headers quite
 right.


* rs/plug-strbuf-leak-in-lock-ref (2014-12-29) 1 commit
  (merged to 'next' on 2015-01-07 at 4d4a600)
 + refs: plug strbuf leak in lock_ref_sha1_basic()


* rs/plug-strbuf-leak-in-merge (2014-12-29) 1 commit
  (merged to 'next' on 2015-01-07 at 2cb8cea)
 + merge: release strbuf after use in suggest_conflicts()


* rs/simplify-parsing-commit-tree-S (2014-12-29) 1 commit
  (merged to 'next' on 2015-01-07 at 51446e0)
 + commit-tree: simplify parsing of option -S using skip_prefix()


* rs/simplify-transport-get (2014-12-29) 1 commit
  (merged to 'next' on 2015-01-07 at cd27fc8)
 + transport: simplify duplicating a substring in transport_get() using xmemdupz()


* sb/dco-indentation-fix (2014-12-22) 1 commit
  (merged to 'next' on 2014-12-23 at c865690)
 + Documentation/SubmittingPatches: unify whitespace/tabs for the DCO


* sb/doc-submitting-patches-keep-notes (2015-01-07) 1 commit
  (merged to 'next' on 2015-01-07 at c362440)
 + SubmittingPatches: explain rationale for using --notes with format-patch


* sb/t5400-remove-unused (2014-12-16) 1 commit
  (merged to 'next' on 2014-12-23 at a992011)
 + t5400: remove dead code


* tf/prompt-preserve-exit-status (2014-12-22) 1 commit
  (merged to 'next' on 2014-12-23 at dfcd89f)
 + git-prompt: preserve value of $? inside shell prompt

 Using the exit status of the last command in the prompt, e.g.
 PS1='$(__git_ps1) $? ', did not work well because the helper
 function stomped on the exit status.

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

* lf/blame-commit-label (2015-01-12) 1 commit
 . blame.c: fix garbled error message

 Needs fixing.


* aw/doc-smtp-ssl-cert-path (2015-01-07) 1 commit
  (merged to 'next' on 2015-01-12 at 61d0b22)
 + correct smtp-ssl-cert-path description

 A long overdue documentation update to match an age-old code
 update.

 Will merge to 'master'.


* mm/complete-rebase-autostash (2015-01-07) 1 commit
  (merged to 'next' on 2015-01-12 at edcdead)

  (merged to 'next' on 2015-01-12 at 9aed017)
 + git-prompt.sh: allow to hide prompt for ignored pwd
 + git-prompt.sh: if pc mode, immediately set PS1 to a plain prompt

 Will merge to 'master'.


* bc/http-fallback-to-password-after-krb-fails (2015-01-07) 1 commit
  (merged to 'next' on 2015-01-12 at 4c67038)
 + remote-curl: fall back to Basic auth if Negotiate fails

 After attempting and failing a password-less authentication
 (e.g. kerberos), libcURL refuses to fall back to password based
 Basic authentication without a bit of help/encouragement.

 Will cook in 'next'.


* bp/diff-relative-config (2015-01-07) 2 commits
 - diff: teach diff.relative to give default to --relative=<value>
 - diff: teach --no-relative to override earlier --relative


* dk/format-patch-ignore-diff-submodule (2015-01-07) 2 commits
  (merged to 'next' on 2015-01-12 at 6b4605b)
 + format-patch: ignore diff.submodule setting
 + t4255: test am submodule with diff.submodule

 Setting diff.submodule to 'log' made "git format-patch" produce
 broken patches.

 Will cook in 'next'.


* nd/attr-optim (2014-12-29) 3 commits
 - attr: avoid heavy work when we know the specified attr is not defined
 - attr: do not attempt to expand when we know it's not a macro

 Will merge to 'master'.


* cj/log-invert-grep (2015-01-12) 1 commit
  (merged to 'next' on 2015-01-12 at 4589ca2)

[Stalled]

* jn/doc-api-errors (2014-12-04) 1 commit
 - doc: document error handling functions and conventions

 For discussion.


* ye/http-accept-language (2014-12-22) 1 commit
 - http: Add Accept-Language header if possible

 Expecting a reroll ($gmane/261810).


* jk/strbuf-doc-to-header (2014-12-12) 4 commits
 - strbuf.h: reorganize api function grouping headers
 - strbuf.h: format asciidoc code blocks as 4-space indent
 - strbuf.h: drop asciidoc list formatting from API docs
 - strbuf: migrate api-strbuf.txt documentation to strbuf.h

 Resolve the "doc vs header" to favor the latter.

 Expecting to be rerolled.


* pw/remote-set-url-fetch (2014-11-26) 1 commit
 - remote: add --fetch and --both options to set-url

 Expecting a reroll.


* ms/submodule-update-config-doc (2014-11-03) 1 commit
 - submodule: clarify documentation for update subcommand

 Needs a reroll ($gmane/259037).


* je/quiltimport-no-fuzz (2014-10-21) 2 commits
 - git-quiltimport: flip the default not to allow fuzz
 - git-quiltimport.sh: allow declining fuzz with --exact option

 "quiltimport" drove "git apply" always with -C1 option to reduce
 context of the patch in order to give more chance to somewhat stale
 patches to apply.  Add an "--exact" option to disable, and also
 "-C$n" option to customize this behaviour.  The top patch
 optionally flips the default to "--exact".

 Tired of waiting for an Ack; will discard.


* tr/remerge-diff (2014-11-10) 9 commits
 - t4213: avoid "|" in sed regexp
 - log --remerge-diff: show what the conflict resolution changed
 - name-hash: allow dir hashing even when !ignore_case
 - merge-recursive: allow storing conflict hunks in index
 - merge_diff_mode: fold all merge diff variants into an enum
 - combine-diff: do not pass revs->dense_combined_merges redundantly
 - merge-recursive: -Xindex-only to leave worktree unchanged
 - merge-recursive: internal flag to avoid touching the worktree
 - merge-recursive: remove dead conditional in update_stages()

 "log -p" output learns a new way to let users inspect a merge
 commit by showing the differences between the automerged result
 with conflicts the person who recorded the merge would have seen
 and the final conflict resolution that was recorded in the merge.

 Waiting for a reroll ($gmane/256591).


* hv/submodule-config (2014-11-11) 4 commits
 - do not die on error of parsing fetchrecursesubmodules option
 - use new config API for worktree configurations of submodules
 - extract functions for submodule config set and lookup
 - implement submodule config cache for lookup of submodule names

 Kicked back to 'pu' per request ($gmane/255610).


* ab/add-interactive-show-diff-func-name (2014-05-12) 2 commits
 - SQUASH??? git-add--interactive: Preserve diff heading when splitting hunks
 - git-add--interactive: Preserve diff heading when splitting hunks

 Waiting for a reroll.

 - userdiff: support Java try keyword
 - userdiff: support C# async methods and correct C# keywords

 Reviews sent; waiting for a response.


* bg/rebase-off-of-previous-branch (2014-04-16) 1 commit
 - git-rebase: print name of rev when using shorthand

 Teach "git rebase -" to report the concrete name of the branch
 (i.e. the previous one).

 But it stops short and does not do the same for "git rebase @{-1}".
 Expecting a reroll.


* rb/merge-prepare-commit-msg-hook (2014-01-10) 4 commits
 - merge: drop unused arg from abort_commit method signature
 - merge: make prepare_to_commit responsible for write_merge_state
 - t7505: ensure cleanup after hook blocks merge
 - t7505: add missing &&

 Expose more merge states (e.g. $GIT_DIR/MERGE_MODE) to hooks that
 run during "git merge".  The log message stresses too much on one
 hook, prepare-commit-msg, but it would equally apply to other hooks
 like post-merge, I think.

 Waiting for a reroll.


* jc/graph-post-root-gap (2013-12-30) 3 commits
 - WIP: document what we want at the end
 - graph: remove unused code a bit
 - graph: stuff the current commit into graph->columns[]

 This was primarily a RFH ($gmane/239580).


* tg/perf-lib-test-perf-cleanup (2013-09-19) 2 commits
 - perf-lib: add test_perf_cleanup target
 - perf-lib: split starting the test from the execution

 Add test_perf_cleanup shell function to the perf suite, that allows
 the script writers to define a test with a clean-up action.

 Will hold.


* jc/show-branch (2014-03-24) 5 commits
 - show-branch: use commit slab to represent bitflags of arbitrary width
 - show-branch.c: remove "all_mask"
 - show-branch.c: abstract out "flags" operation
 - show-branch.c: lift all_mask/all_revs to a global static
 - show-branch.c: update comment style

 Waiting for the final step to lift the hard-limit before sending it out.

* jn/rerere-fail-on-auto-update-failure (2015-01-08) 1 commit
  (merged to 'next' on 2015-01-12 at 313c449)
 + rerere: error out on autoupdate failure

 "git rerere" (invoked internally from many mergy operations) did
 not correctly signal errors when told to update the working tree
 files and failed to do so for whatever reason.

 Will cook in 'next'.


* jk/prune-packed-server-info (2015-01-06) 2 commits

 + update-server-info: create info/* with mode 0666
 + t1301: set umask in reflog sharedrepository=group test

 Fix recent breakage in Git 2.2 that started creating info/refs and
 objects/info/packs files with permission bits tighter than user's
 umask.

 Will merge to 'master'.


* km/imap-send-libcurl-options (2015-01-06) 2 commits
  (merged to 'next' on 2015-01-12 at 5bb8802)
 + imap-send.c: set CURLOPT_USE_SSL to CURLUSESSL_TRY
 + imap-send.c: support GIT_CURL_VERBOSE

 Now imap-send learned to talk to the server using cURL library,

* rh/test-color-avoid-terminfo-in-original-home (2015-01-07) 2 commits
  (merged to 'next' on 2015-01-12 at eac0b93)
 + test-lib.sh: do tests for color support after changing HOME
 + test-lib: use 'test ...' instead of '[ ... ]'

 We try to see if "tput" gives a useful result before switching TERM
 to dumb and moving HOME to point to our fake location for stability
 of the tests, and then use the command when coloring the output
 from the tests, but there is no guarantee "tput" works after
 switching HOME.

* sp/subtree-doc (2015-01-06) 1 commit
  (merged to 'next' on 2015-01-12 at 7c488d6)

* js/remote-add-with-insteadof (2014-12-23) 2 commits
  (merged to 'next' on 2015-01-12 at ccff14f)
 + Add a regression test for 'git remote add <existing> <same-url>'
 + git remote: allow adding remotes agreeing with url.<...>.insteadOf

 "git remote add $name $URL" is now allowed when "url.$URL.insteadOf"
 is already defined.

 Will merge to 'master'.


* sb/atomic-push (2015-01-07) 10 commits
  (merged to 'next' on 2015-01-12 at 411c6a6)
 + t5543-atomic-push.sh: add basic tests for atomic pushes
 + push.c: add an --atomic argument
 + send-pack.c: add --atomic command line argument
 + send-pack: rename ref_update_to_be_sent to check_to_send_update
 + receive-pack.c: negotiate atomic push support
 + receive-pack.c: add execute_commands_atomic function
 + receive-pack.c: move transaction handling in a central place
 + receive-pack.c: move iterating over all commands outside execute_commands
 + receive-pack.c: die instead of error in case of possible future bug
 + receive-pack.c: shorten the execute_commands loop over all commands
 (this branch uses mh/reflog-expire.)

 "git push" has been taught a "--atomic" option that makes push to
 update more than one ref an "all-or-none" affair.

 Will cook in 'next'.


* mh/reflog-expire (2014-12-22) 24 commits
  (merged to 'next' on 2015-01-12 at 12a7dff)
 + refs.c: let fprintf handle the formatting

 + struct expire_reflog_cb: a new callback data type
 + Rename expire_reflog_cb to expire_reflog_policy_cb
 + expire_reflog(): move updateref to flags argument
 + expire_reflog(): move dry_run to flags argument
 + expire_reflog(): add a "flags" argument
 + expire_reflog(): extract two policy-related functions
 + Extract function should_expire_reflog_ent()
 + expire_reflog(): use a lock_file for rewriting the reflog file
 + expire_reflog(): return early if the reference has no reflog
 + expire_reflog(): rename "ref" parameter to "refname"
 + expire_reflog(): it's not an each_ref_fn anymore
 + refs.c: add a function to append a reflog entry to a fd
 + refs.c: make ref_transaction_delete a wrapper for ref_transaction_update
 + refs.c: make ref_transaction_create a wrapper for ref_transaction_update
 (this branch is used by sb/atomic-push.)

 Restructure "reflog expire" to fit the reflogs better with the
 recently updated ref API.

 Looked reasonable (except that some shortlog entries stood out like
 a sore thumb).

 Will cook in 'next'.

 + receive-pack: support push-to-checkout hook
 + receive-pack: refactor updateInstead codepath

 Extending the js/push-to-deploy topic, the behaviour of "git push"
 when updating the working tree and the index with an update to the
 branch that is checked out can be tweaked by push-to-checkout hook.

 Will cook in 'next'.

* jc/push-cert-hmac-optim (2014-09-25) 2 commits
 . receive-pack: truncate hmac early and convert only necessary bytes
 . sha1_to_hex: split out "hex-format n bytes" helper and use it

 This is "we could do this if we wanted to", not "we measured and it
 improves performance critical codepath".


* mt/patch-id-stable (2014-06-10) 1 commit
 . patch-id: change default to stable

 Nobody seems to be jumping up & down requesting this last step,
 which makes the result somewhat backward incompatible.


* sb/copy-fd-errno (2014-11-17) 1 commit
 . copy.c: make copy_fd preserve meaningful errno


* cj/grep-none-match (2015-01-06) 1 commit
 . git-log: added --none-match option

 "git log --none-match --grep=WIP" will show only commits that are
 not marked as WIP.

 cj/log-invert-grep replaces this.
