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

More topics merged to 'master', some of which have been cooking
before the v1.9.0 final release, many of them fallouts from GSoC
microprojects.  Many topics that have been marked to be discarded
are finally discarded.

Quite a few topics are still outside 'pu' and I suspect some of the
larger ones deserve deeper reviews to help moving them to 'next'.
In principle, I'd prefer to keep any large topic that touch core
part of the system cooking in 'next' for at least a full cycle, and
the sooner they get merged to 'next', the better.  Help is greatly

* jk/lib-terminal-lazy (2014-03-14) 1 commit
  (merged to 'next' on 2014-03-20 at 5de832f)
 + t/lib-terminal: make TTY a lazy prerequisite

 The test helper lib-terminal always run an actual test_expect_* when
 included, which screwed up with the use of skil-all that may have to
 be done later.

 Will merge to 'master'.

* ah/doc-gitk-config (2014-03-20) 1 commit
  (merged to 'next' on 2014-03-20 at d671b60)

* jk/pack-bitmap (2014-03-17) 1 commit
  (merged to 'next' on 2014-03-20 at bba6246)
 + pack-objects: turn off bitmaps when skipping objects

 Instead of dying when asked to (re)pack with the reachability
 bitmap when a bitmap cannot be built, just (re)pack without
 producing a bitmap in such a case, with a warning.

 Will merge to 'master', and probably to 'maint' later.

* jk/pack-bitmap-progress (2014-03-17) 2 commits
  (merged to 'next' on 2014-03-20 at c7a83f9)
 + pack-objects: show reused packfile objects in "Counting objects"
 + pack-objects: show progress for reused packfiles

 The progress output while repacking and transferring objects showed
 an apparent large silence while writing the objects out of existing
 packfiles, when the reachability bitmap was in use.

 Will merge to 'master', and probably to 'maint' later.

* jk/subtree-prefix (2014-03-17) 1 commit
  (merged to 'next' on 2014-03-20 at 81367fa)
 + subtree: initialize "prefix" variable

 A stray environment variable $prefix could have leaked into and
 affected the behaviour of the "subtree" script.

 Will merge to 'master'.

* sz/mingw-index-pack-threaded (2014-03-19) 1 commit
 - Enable index-pack threading in msysgit.

 Still under discussion among Windows folks


* bc/blame-crlf-test (2014-02-18) 1 commit
 - blame: add a failing test for a CRLF issue.

 I have a feeling that a fix for this should be fairly isolated and
 trivial (it should be just the matter of paying attention to the
 crlf settings when synthesizing the fake commit)---perhaps somebody
 can squash in a fix to this?

* jk/makefile (2014-02-05) 16 commits
 - move LESS/LV pager environment to Makefile
 - Makefile: teach scripts to include make variables
 - Makefile: auto-build C strings from make variables
 - Makefile: drop *_SQ variables
 - Makefile: add c-quote helper function
 - Makefile: introduce sq function for shell-quoting
 - Makefile: always create files via make-var
 - Makefile: store GIT-* sentinel files in MAKE/
 - Makefile: prefer printf to echo for GIT-*
 - 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.

* kb/fast-hashmap-pack-struct (2014-02-24) 1 commit
 - hashmap.h: make sure map entries are tightly packed

 I am inclined to drop this; an alternative is to replace it with
 the "more portable" one that uses #pragma, which I am willing to
 try doing so on 'pu', though.

* 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.

 Will hold.

* 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.

* jl/submodule-recursive-checkout (2013-12-26) 5 commits
 - Teach checkout to recursively checkout submodules
 - submodule: teach unpack_trees() to update submodules
 - submodule: teach unpack_trees() to repopulate submodules
 - submodule: teach unpack_trees() to remove submodule contents
 - submodule: prepare for recursive checkout of submodules

 Expecting 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).

* hv/submodule-ignore-fix (2013-12-06) 4 commits
 - disable complete ignorance of submodules for index <-> HEAD diff
 - always show committed submodules in summary after commit
 - teach add -f option for ignored submodules
 - fix 'git add' to skip submodules configured as ignored

 Teach "git add" to be consistent with "git status" when changes to
 submodules are set to be ignored, to avoid surprises after checking
 with "git status" to see there isn't any change to be further added
 and then see that "git add ." adds changes to them.

 I think a reroll is coming, so this may need to be replaced, but I
 needed some practice with heavy conflict resolution.  It conflicts
 with two changes to "git add" that have been scheduled for Git 2.0
 quite badly, and I think I got the resolution right this time.

 Waiting for a reroll.

* np/pack-v4 (2013-09-18) 90 commits
 . packv4-parse.c: add tree offset caching
 . t1050: replace one instance of show-index with verify-pack

 . 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.

 Temporarily ejected from 'pu', to try out jk/pack-bitmap, which
 this topic conflicts with.

* 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/format-patch (2013-04-22) 2 commits
 - format-patch: --inline-single
 - format-patch: rename "no_inline" field

 A new option to send a single patch to the standard output to be
 appended at the bottom of a message.  I personally have no need for
 this, but it was easy enough to cobble together.  Tests, docs and
 stripping out more MIMEy stuff are left as exercises to interested

* jc/show-branch (2013-06-07) 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.

  (merged to 'next' on 2014-03-14 at 8ac862c)

 + wt-status: i18n of section labels
 + wt-status: extract the code to compute width for labels
 + wt-status: make full label string to be subject to l10n

 Unify the codepaths that format new/modified/changed sections and
 conflicted paths in the "git status" output and make it possible to
 properly internationalize their output.

 Will merge to 'master'.

* pw/branch-config-message (2014-03-13) 1 commit
 - install_branch_config(): simplify verbose messages logic

 Among the many attempts to microproject #8, this seemed to be the
 most "done" among the table based ones; I however tend to think
 that the original with minimum refactoring would be easier to read.

* ys/fsck-commit-parsing (2014-03-19) 2 commits

 + stash pop: mention we did not drop the stash upon failing to apply

 "stash pop", upon failing to apply the stash, refrains from
 discarding the stash to avoid information loss.  Be more explicit
 in the error message.

 The wording may want to get a bit more bikeshedding.

* cn/fetch-prune-overlapping-destination (2014-02-28) 2 commits
 - fetch: handle overlaping refspecs on --prune

  (merged to 'next' on 2014-03-14 at ff375fc)
 + skip_prefix(): scan prefix only once

 Update implementation of skip_prefix() to scan only once; given
 that most "prefix" arguments to the inline function are constant
 strings whose strlen() can be determined at the compile time, this
 might actually make things worse with a compiler with sufficient

 Serving objects from a shallow repository needs to write a

 - tree-diff: rework diff_tree() to generate diffs for multiparent cases as well
 - Portable alloca for Git
 - tree-diff: reuse base str(buf) memory on sub-tree recursion
 - tree-diff: no need to call "full" diff_tree_sha1 from show_path()
 - tree-diff: rework diff_tree interface to be sha1 based
 - tree-diff: diff_tree() should now be static
 - tree-diff: remove special-case diff-emitting code for empty-tree cases
 - tree-diff: simplify tree_entry_pathcmp
 - tree-diff: show_path prototype is not needed anymore
 - tree-diff: rename compare_tree_entry -> tree_entry_pathcmp
 - tree-diff: move all action-taking code out of compare_tree_entry()
 - tree-diff: don't assume compare_tree_entry() returns -1,0,1
 - tree-diff: consolidate code for emitting diffs and recursion in one place
 - tree-diff: show_tree() is not needed
 - tree-diff: no need to pass match to skip_uninteresting()
 - tree-diff: no need to manually verify that there is no mode change for a path
 - combine-diff: move changed-paths scanning logic into its own function
 - combine-diff: move show_log_first logic/action out of paths scanning

 Instead of running N pair-wise diff-trees when inspecting a
 N-parent merge, find the set of paths that were touched by walking
 N+1 trees in parallel.  These set of paths can then be turned into
 N pair-wise diff-tree results to be processed through rename
 detections and such.  And N=2 case nicely degenerates to the usual
 2-way diff-tree, which is very nice.

* nd/log-show-linear-break (2014-03-20) 2 commits
 - log: add --show-linear-break to help see non-linear history
 - object.h: centralize object flag allocation

 Attempts to show where a single-strand-of-pearls break in "git log"

 The implementation seems to have got worse compared to the previous
 round.  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.

 RFC.  This latest round clashes with the kb/fast-hashmap topic in

* lt/request-pull (2014-03-13) 6 commits
  (merged to 'next' on 2014-03-17 at 21a598d)
 + request-pull: documentation updates
 + request-pull: resurrect "pretty refname" feature
 + request-pull: test updates
 + request-pull: pick up tag message as before
 + request-pull: allow "local:remote" to specify names on both ends
 + request-pull: more strictly match local/remote branches

 Discard the accumulated "heuristics" to guess from which branch the
 result wants to be pulled from and make sure what the end user
 specified is not second-guessed by "git request-pull", to avoid

 Will merge to 'master'.

* cc/interpret-trailers (2014-03-07) 11 commits
 - Documentation: add documentation for 'git interpret-trailers'
 - trailer: add tests for commands in config file
 - trailer: execute command from 'trailer.<name>.command'
 - trailer: add tests for "git interpret-trailers"
 - trailer: add interpret-trailers command
 - trailer: put all the processing together and print
 - trailer: parse trailers from stdin
 - trailer: process command line trailer arguments
 - trailer: read and process config information
 - trailer: process trailers from stdin and arguments
 - trailers: add data structures and basic functions

 A new filter to programatically edit the tail end of the commit log

* 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.
