What's cooking in git.git (Jun 2014, #04; Tue, 17)
--------------------------------------------------

Here are the topics that have been cooking.  Commits prefixed with
'-' are only in 'pu' (proposed updates) while commits prefixed with
'+' are in 'next'.

Many topics that have been cooking in 'next' during the previous
cycle, totalling close to 300 individual patches, are in 'master'
now.  We have also accumulated some fixes we need to merge down to
'maint' and cut a v2.0.1 sometime next week.

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"]

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

 Teaches "git patch-id" to compute the patch ID that does not change
 when the files in a single patch is reordered. As this new algorithm
 is backward incompatible, the last bit to flip it to be the default
 is left out of 'master' for now.


* as/pretty-truncate (2014-05-21) 5 commits
  (merged to 'next' on 2014-06-10 at d8147a2)
 + pretty.c: format string with truncate respects logOutputEncoding
 + t4205, t6006: add tests that fail with i18n.logOutputEncoding set
 + t4205 (log-pretty-format): use `tformat` rather than `format`
 + t4041, t4205, t6006, t7102: don't hardcode tested encoding value
 + t4205 (log-pretty-formats): don't hardcode SHA-1 in expected outputs

 Originally merged to 'next' on 2014-05-30

 Compatibility enhancement for Solaris.


* cc/replace-edit (2014-05-19) 10 commits
  (merged to 'next' on 2014-06-10 at ff69722)
 + Documentation: replace: describe new --edit option

 + refs.c: optimize check_refname_component()
 (this branch is used by dt/refs-check-refname-component-sse42.)

 Originally merged to 'next' on 2014-06-06

* jk/complete-merge-pull (2014-05-27) 2 commits
  (merged to 'next' on 2014-06-10 at d1524c5)
 + completion: add missing options for git-merge
 + completion: add a note that merge options are shared

 Originally merged to 'next' on 2014-06-06

 The completion code did not know about quite a few options that are
 common between "git merge" and "git pull", and a couple of options
 unique to "git merge".


* jk/daemon-tolower (2014-05-23) 1 commit
  (merged to 'next' on 2014-06-10 at f3c549d)
 + daemon/config: factor out duplicate xstrdup_tolower

 Originally merged to 'next' on 2014-05-21

  (merged to 'next' on 2014-06-10 at 299ea28)

 Originally merged to 'next' on 2014-05-21

  (merged to 'next' on 2014-06-10 at 01e6983)
 + strbuf: add strbuf_tolower function

 Originally merged to 'next' on 2014-05-23


* jl/remote-rm-prune (2014-05-27) 3 commits
  (merged to 'next' on 2014-06-10 at 13259ff)
 + remote prune: optimize "dangling symref" check/warning
 + remote: repack packed-refs once when deleting multiple refs
 + remote rm: delete remote configuration as the last

 Originally merged to 'next' on 2014-06-06

 "git remote rm" and "git remote prune" can involve removing many
 refs at once, which is not a very efficient thing to do when very
 many refs exist in the packed-refs file.


* jl/status-added-submodule-is-never-ignored (2014-04-07) 2 commits
  (merged to 'next' on 2014-06-10 at fc63847)
 + commit -m: commit staged submodules regardless of ignore config
 + status/commit: show staged submodules regardless of ignore config

 Originally merged to 'next' on 2014-06-06

 submodule.*.ignore and diff.ignoresubmodules are used to ignore all
 submodule changes in "diff" output, but it can be confusing to
 apply these configuration values to status and commit.

 This is a backward-incompatible change, but should be so in a good
 way (aka bugfix).


* jm/dedup-test-config (2014-06-05) 1 commit
  (merged to 'next' on 2014-06-10 at 8966f54)
 + t/t7810-grep.sh: remove duplicate test_config()

 Originally merged to 'next' on 2014-06-06

 Originally merged to 'next' on 2014-06-06


* jm/format-patch-mail-sig (2014-05-27) 2 commits
  (merged to 'next' on 2014-06-10 at 310f59e)

  (merged to 'next' on 2014-06-10 at 034f13d)

  (merged to 'next' on 2014-06-10 at f149f4a)

* nd/daemonize-gc (2014-05-27) 1 commit
  (merged to 'next' on 2014-06-10 at 6fae7b0)
 + gc --auto: do not lock refs in the background

 Originally merged to 'next' on 2014-06-06

 "git gc --auto" was recently changed to run in the background to
 give control back early to the end-user sitting in front of the
 terminal, but it forgot that housekeeping involving reflogs should
 be done without other processes competing for accesses to the refs.


* ow/config-mailmap-pathname (2014-05-27) 1 commit
  (merged to 'next' on 2014-06-10 at aba4ca2)
 + config: respect '~' and '~user' in mailmap.file

 Originally merged to 'next' on 2014-06-06

 mailmap.file configuration names a pathname, hence should honor
 ~/path and ~user/path as its value.


* rr/rebase-autostash-fix (2014-05-20) 2 commits
  (merged to 'next' on 2014-06-10 at afd0c29)
 + rebase -i: test "Nothing to do" case with autostash
 + rebase -i: handle "Nothing to do" case with autostash

 Originally merged to 'next' on 2014-05-21

 Originally merged to 'next' on 2014-06-06

 hashtable used in pack-objects.

  (merged to 'next' on 2014-06-10 at 7cedf2d)

 Originally merged to 'next' on 2014-06-06


* sk/test-cmp-bin (2014-06-04) 1 commit
  (merged to 'next' on 2014-06-10 at 020a475)
 + t5000, t5003: do not use test_cmp to compare binary files

 Originally merged to 'next' on 2014-06-06

  (merged to 'next' on 2014-06-10 at 8d03e5a)

* 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.


* tr/merge-recursive-index-only (2014-02-05) 3 commits
 - 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()
 (this branch is used by tr/remerge-diff.)

 Will hold.


* tr/remerge-diff (2014-02-26) 5 commits
 . 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
 . revision: fold all merge diff variants into an enum merge_diff_mode
 . combine-diff: do not pass revs->dense_combined_merges redundantly
 (this branch uses tr/merge-recursive-index-only.)

 "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.

 Needs to be rebased, now kb/fast-hashmap topic is in.

 . Makefile: use tempfile/mv strategy for GIT-*
 . Makefile: introduce make-var helper function
 . Makefile: fix git-instaweb dependency on gitweb
 . Makefile: drop USE_GETTEXT_SCHEME from GIT-CFLAGS

 Simplify the Makefile rules and macros that exist primarily for
 quoting purposes, and make it easier to robustly express the
 dependency rules.

 Expecting a reroll.


* po/everyday-doc (2014-01-27) 1 commit
 - Make 'git help everyday' work

 This may make the said command to emit something, but the source is
 not meant to be formatted into a manual pages to begin with, and
 also its contents are a bit stale.  It may be a good first step in
 the right direction, but needs more work to at least get the
 mark-up right before public consumption.

 Will hold.


* jk/branch-at-publish-rebased (2014-01-17) 5 commits
 . t1507 (rev-parse-upstream): fix typo in test title
 . implement @{publish} shorthand
 . branch_get: provide per-branch pushremote pointers
 . branch_get: return early on error
 . sha1_name: refactor upstream_mark

 Give an easier access to the tracking branches from "other" side in
 a triangular workflow by introducing B@{publish} that works in a
 similar way to how B@{upstream} does.

 Meant to be used as a basis for whatever Ram wants to build on.

 Ejected from 'pu' to unclutter.


* fc/publish-vs-upstream (2014-04-21) 8 commits
 . sha1_name: add support for @{publish} marks
 . sha1_name: simplify track finding
 . sha1_name: cleanup interpret_branch_name()
 . branch: display publish branch
 . push: add --set-publish option
 . branch: add --set-publish-to option
 . Add concept of 'publish' branch
 . t5516 (fetch-push): fix test restoration

 Add branch@{publish}; it seems that this is somewhat different from
 Ram and Peff started working on.  At least the tip needs to be
 rerolled not to squat on @{p} which @{push} and possibly @{pull}
 may want to share.


* 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

 . unpack-objects: allow to save processed bytes to a buffer
 - ...

 Nico and Duy advancing the eternal vaporware pack-v4.  This is here
 primarily for wider distribution of the preview edition.

 Needs to be rebased, now the pack-bitmap series is in.


* 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.

 "git log -2master" is a common typo that shows two commits starting
 from whichever random branch that is not 'master' that happens to
 be checked out currently.

 Will merge to 'master'.

 validate GPG signatures in commit objects.
