What's cooking in git.git (Aug 2009, #05; Wed, 26)
--------------------------------------------------

Here are the topics that have been cooking.  Commits prefixed with '-' are
only in 'pu' 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.

After the 1.6.5 cycle, the next release will be 1.7.0, and we will push
out the planned "push safety" change.  1.7.0 would be a good time to
introduce "justifiable" changes that are not strictly backward compatible.

During 1.6.5 cycle, 'next' will hold topics meant for 1.6.5 and 1.7.0.

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

* aj/fix-read-tree-from-scratch (2009-08-17) 1 commit
  (merged to 'next' on 2009-08-20 at 7a04133)
 + read-tree: Fix regression with creation of a new index file.

* jc/maint-checkout-index-to-prefix (2009-08-16) 1 commit
  (merged to 'next' on 2009-08-20 at 2f6aea2)

  (merged to 'next' on 2009-08-14 at a702e78)
 + git submodule summary: add --files option

* lh/short-decorate (2009-08-15) 1 commit
  (merged to 'next' on 2009-08-18 at b8c1d96)
 + git-log: allow --decorate[=short|full]

* oa/stash-na (2009-08-11) 1 commit
  (merged to 'next' on 2009-08-14 at 12c2e2b)
 + git stash: Give friendlier errors when there is nothing to apply
--------------------------------------------------
[New Topics]

* np/maint-1.6.3-deepen (2009-08-24) 1 commit.
  (merged to 'next' on 2009-08-25 at 8e383d4)
 + fix simple deepening of a repo

* jk/maint-1.6.3-checkout-unborn (2009-08-24) 1 commit.
  (merged to 'next' on 2009-08-25 at 5f29625)
 + checkout: do not imply "-f" on unborn branches

* mr/gitweb-snapshot (2009-08-25) 3 commits
 - gitweb: add t9501 tests for checking HTTP status codes
 - gitweb: split test suite into library and tests
 - gitweb: improve snapshot error handling
--------------------------------------------------
[Stalled]

* js/stash-dwim (2009-07-27) 1 commit.
  (merged to 'next' on 2009-08-16 at 67896c4)
 + Make 'git stash -k' a short form for 'git stash save --keep-index'
 (this branch is used by tr/reset-checkout-patch.)

* tr/reset-checkout-patch (2009-08-18) 8 commits.
  (merged to 'next' on 2009-08-18 at e465bb3)
 + tests: disable interactive hunk selection tests if perl is not available
  (merged to 'next' on 2009-08-16 at 67896c4)
 + DWIM 'git stash save -p' for 'git stash -p'
 + Implement 'git stash save --patch'
 + Implement 'git checkout --patch'
 + Implement 'git reset --patch'
 + builtin-add: refactor the meat of interactive_add()
 + Add a small patch-mode testing library
 + git-apply--interactive: Refactor patch mode code
 (this branch uses js/stash-dwim.)

There was a discussion on better DWIMmery for the above two topics to (1)
forbid "git stash save --anything-with-dash" and (2) redirect with any
option "git stash --opt" to "git stash save --opt", to keep it flexible
and safe at the same time.  I think it is a sane thing to do, but nothing
has happened lately.

* jn/gitweb-blame (2009-08-06) 3 commits
 - gitweb: Create links leading to 'blame_incremental' using JavaScript
 - gitweb: Incremental blame (WIP)
 - gitweb: Add optional "time to generate page" info in footer

Ajax-y blame WIP

* db/vcs-helper (2009-08-09) 17 commits
 - Allow helpers to request marks for fast-import
 - Allow helpers to report in "list" command that the ref is unchanged
 - Add support for "import" helper command
 - transport-helper_init(): fix a memory leak in error path
 - Add a config option for remotes to specify a foreign vcs
 - Allow programs to not depend on remotes having urls
 - Allow fetch to modify refs
 - Use a function to determine whether a remote is valid
 - Use a clearer style to issue commands to remote helpers
  (merged to 'next' on 2009-08-07 at f3533ba)
 + Makefile: install hardlinks for git-remote-<scheme> supported by libcurl if possible
 + Makefile: do not link three copies of git-remote-* programs
 + Makefile: git-http-fetch does not need expat
  (merged to 'next' on 2009-08-06 at 15da79d)
 + http-fetch: Fix Makefile dependancies
 + Add transport native helper executables to .gitignore
  (merged to 'next' on 2009-08-05 at 33d491e)
 + git-http-fetch: not a builtin
 + Use an external program to implement fetching with curl
 + Add support for external programs for handling native fetches
 (this branch is used by jh/cvs-helper.)

There was a discussion that suggests that the use of colon ':' before vcs
helper name needs to be corrected.  Nothing happened since.

* je/send-email-no-subject (2009-08-05) 1 commit
 - send-email: confirm on empty mail subjects

This seems to break t9001.  Near the tip of 'pu' I have a iffy
workaround.
--------------------------------------------------
[Cooking]

* mm/reset-report (2009-08-21) 2 commits
  (merged to 'next' on 2009-08-25 at f2a4424)
 + reset: make the reminder output consistent with "checkout"
 + Rename REFRESH_SAY_CHANGED to REFRESH_IN_PORCELAIN.

* wl/insta-mongoose (2009-08-21) 1 commit
  (merged to 'next' on 2009-08-25 at da1d566)
 + Add support for the Mongoose web server.

* lt/approxidate (2009-08-22) 2 commits
  (merged to 'next' on 2009-08-26 at 62853f9)
 + Further 'approxidate' improvements
 + Improve on 'approxidate'

Fixes a few "reasonably formatted but thus-far misparsed" date strings.
As Nico suggested, we would need a test to prevent regression to existing
support for date strings that are "reasonably formatted".

* jc/mailinfo-scissors (2009-08-25) 2 commits
 - Documentation: describe the scissors mark support of "git am"
 - Teach mailinfo to ignore everything before -- >8 -- mark

* tf/diff-whitespace-incomplete-line (2009-08-23) 2 commits.
  (merged to 'next' on 2009-08-26 at 4fc7784)
 + xutils: Fix xdl_recmatch() on incomplete lines
 + xutils: Fix hashing an incomplete line with whitespaces at the end

* cc/sequencer-rebase-i (2009-08-21) 17 commits.
 - rebase -i: use "git sequencer--helper --cherry-pick"
 - sequencer: add "--cherry-pick" option to "git sequencer--helper"
 - sequencer: add "do_commit()" and related functions
 - pick: libify "pick_help_msg()"
 - revert: libify pick
 - rebase -i: use "git sequencer--helper --fast-forward"
 - sequencer: let "git sequencer--helper" callers set "allow_dirty"
 - sequencer: add "--fast-forward" option to "git sequencer--helper"
 - sequencer: add "do_fast_forward()" to perform a fast forward
 - rebase -i: use "git sequencer--helper --reset-hard"
 - sequencer: add "--reset-hard" option to "git sequencer--helper"
 - sequencer: add comments about reset_almost_hard()
 - sequencer: add "reset_almost_hard()" and related functions
 - rebase -i: use "git sequencer--helper --make-patch"
 - sequencer: free memory used in "make_patch" function
 - sequencer: add "make_patch" function to save a patch
 - sequencer: add "builtin-sequencer--helper.c"

Migrating "rebase -i" bit by bit to C.  I am inclined to agree with Dscho
that maybe this approach forces the migration to follow the structure of
the shell script too much, and could force a suboptimal end result, but
we'll see.

* as/maint-graph-interesting-fix (2009-08-21) 2 commits.
  (merged to 'next' on 2009-08-25 at 9d5e215)
 + Add tests for rev-list --graph with options that simplify history
 + graph API: fix bug in graph_is_interesting()

Looked sane.

* jc/shortstatus (2009-08-15) 11 commits
  (merged to 'next' on 2009-08-15 at 7e40766)
 + git commit --dry-run -v: show diff in color when asked
 + Documentation/git-commit.txt: describe --dry-run
  (merged to 'next' on 2009-08-12 at 53bda17)
 + wt-status: collect untracked files in a separate "collect" phase
 + Make git_status_config() file scope static to builtin-commit.c
 + wt-status: move wt_status_colors[] into wt_status structure
 + wt-status: move many global settings to wt_status structure
 + commit: --dry-run
  (merged to 'next' on 2009-08-06 at fe8cb94)
 + status: show worktree status of conflicted paths separately
 + wt-status.c: rework the way changes to the index and work tree are summarized
 + diff-index: keep the original index intact
 + diff-index: report unmerged new entries
 (this branch is used by jc/1.7.0-status.)

Will cook for a bit more and then merge.

* jc/maint-unpack-objects-strict (2009-08-13) 1 commit.
  (merged to 'next' on 2009-08-23 at 38eb750)
 + Fix "unpack-objects --strict"

Will merge.

* jh/submodule-foreach (2009-08-20) 9 commits
  (merged to 'next' on 2009-08-20 at 671bea4)
 + git clone: Add --recursive to automatically checkout (nested) submodules
 + t7407: Use 'rev-parse --short' rather than bash's substring expansion notation
  (merged to 'next' on 2009-08-18 at f4a881d)
 + git submodule status: Add --recursive to recurse into nested submodules
 + git submodule update: Introduce --recursive to update nested submodules
 + git submodule foreach: Add --recursive to recurse into nested submodules
 + git submodule foreach: test access to submodule name as '$name'
 + Add selftest for 'git submodule foreach'
 + git submodule: Cleanup usage string and add option parsing to cmd_foreach()
 + git submodule foreach: Provide access to submodule name, as '$name'

Will merge.

* jh/notes (2009-07-29) 8 commits.
 - t3302-notes-index-expensive: Speed up create_repo()
 - fast-import: Add support for importing commit notes
 - First draft of notes tree parser with support for fanout subtrees
 - Teach "-m <msg>" and "-F <file>" to "git notes edit"
 - Add an expensive test for git-notes
 - Speed up git notes lookup
 - Add a script to edit/inspect notes
 - Introduce commit notes

The cvs-helper series depends on this one.  I have a recollection
that some people were not happy about the fan-out of the notes tree
layout, but has the issue been resolved to a concensus?

* ne/rev-cache (2009-08-21) 6 commits
 . support for path name caching in rev-cache
 . full integration of rev-cache into git, completed test suite
 . administrative functions for rev-cache, start of integration into git
 . support for non-commit object caching in rev-cache
 . basic revision cache system, no integration or features
 . man page and technical discussion for rev-cache

Updated but seems to break upload-pack tests when merged to 'pu'; given
what this series touches, breakages in that area are expected.
May discard if a working reroll comes, to give it a fresh start.

* jh/cvs-helper (2009-08-18) 7 commits
 - More fixes to the git-remote-cvs installation procedure
 - Fix the Makefile-generated path to the git_remote_cvs package in git-remote-cvs
 - Add simple selftests of git-remote-cvs functionality
 - git-remote-cvs: Remote helper program for CVS repositories
 - 2/2: Add Python support library for CVS remote helper
 - 1/2: Add Python support library for CVS remote helper
 - Basic build infrastructure for Python scripts
 (this branch uses db/vcs-helper.)

Builds on db/vcs-helper (which is stalled, so this cannot move).

The testing of Python part seemed to be still fragile even with the latest
fix on one of my boches with an earlier round already installed, but I
didn't look very deeply before removing the older installation.

* sr/gfi-options (2009-08-24) 4 commits
 - fast-import: test the new option command
 - fast-import: add option command
 - fast-import: put marks reading in it's own function
 - fast-import: put option parsing code in seperate functions

Will merge to 'next' shortly.

* lt/block-sha1 (2009-08-17) 4 commits
  (merged to 'next' on 2009-08-18 at 67a1ce8)
 + remove ARM and Mozilla SHA1 implementations
 + block-sha1: guard gcc extensions with __GNUC__
 + make sure byte swapping is optimal for git
 + block-sha1: make the size member first in the context struct

May merge soon; Solaris performance patches that was discussed
earlier can happen on 'master', as the series is usable as-is.

* nd/sparse (2009-08-20) 20 commits
 - sparse checkout: inhibit empty worktree
 - Add tests for sparse checkout
 - read-tree: add --no-sparse-checkout to disable sparse checkout support
 - unpack-trees(): ignore worktree check outside checkout area
 - unpack_trees(): apply $GIT_DIR/info/sparse-checkout to the final index
 - unpack-trees(): "enable" sparse checkout and load $GIT_DIR/info/sparse-checkout
 - unpack-trees.c: generalize verify_* functions
 - unpack-trees(): add CE_WT_REMOVE to remove on worktree alone
 - Introduce "sparse checkout"
 - dir.c: export excluded_1() and add_excludes_from_file_1()
 - excluded_1(): support exclude files in index
 - unpack-trees(): carry skip-worktree bit over in merged_entry()
 - Read .gitignore from index if it is skip-worktree
 - Avoid writing to buffer in add_excludes_from_file_1()
 - Teach Git to respect skip-worktree bit (writing part)
 - Teach Git to respect skip-worktree bit (reading part)
 - Introduce "skip-worktree" bit in index, teach Git to get/set this bit
 - Add test-index-version
 - update-index: refactor mark_valid() in preparation for new options
  (merged to 'next' on 2009-08-20 at ea167d7)
 + Prevent diff machinery from examining assume-unchanged entries on worktree

The first one was an independent fix; the rest has been replaced with the
"return of no-checkout" series.
--------------------------------------------------
[For 1.7.0]

* jc/1.7.0-status (2009-08-15) 3 commits
  (merged to 'next' on 2009-08-22 at b3507bb)
 + git status: not "commit --dry-run" anymore
 + git stat -s: short status output
 + git stat: the beginning of "status that is not a dry-run of commit"
 (this branch uses jc/shortstatus.)

With this, "git status" is no longer "git commit --preview".

* jc/1.7.0-send-email-no-thread-default (2009-08-22) 1 commit
  (merged to 'next' on 2009-08-22 at 5106de8)
 + send-email: make --no-chain-reply-to the default

* jc/1.7.0-diff-whitespace-only-status (2009-05-23) 2 commits.
  (merged to 'next' on 2009-08-02 at 9c08420)
 + diff: Rename QUIET internal option to QUICK
 + diff: change semantics of "ignore whitespace" options

This changes exit code from "git diff --ignore-whitespace" and friends
when there is no actual output.  It is a backward incompatible change, but
we could argue that it is a bugfix.

* jc/1.7.0-push-safety (2009-02-09) 2 commits
  (merged to 'next' on 2009-08-02 at 38b82fe)
 + Refuse deleting the current branch via push
 + Refuse updating the current branch in a non-bare repository via push
--------------------------------------------------
[I have been too busy to purge these]

* jc/log-tz (2009-03-03) 1 commit.
 - Allow --date=local --date=other-format to work as expected

Maybe some people care about this.  I dunno.

* jc/mailinfo-remove-brackets (2009-07-15) 1 commit.
 - mailinfo: -b option keeps [bracketed] strings that is not a [PATCH] marker

Maybe some people care about this.  I dunno.

* lt/read-directory (2009-05-15) 3 commits.
 . Add initial support for pathname conversion to UTF-8
 . read_directory(): infrastructure for pathname character set conversion
 . Add 'fill_directory()' helper function for directory traversal

* ps/blame (2009-03-12) 1 commit.
 . blame.c: start libifying the blame infrastructure

* pb/tracking (2009-07-16) 7 commits.
 . branch.c: if remote is not config'd for branch, don't try delete push config
 . branch, checkout: introduce autosetuppush
 . move deletion of merge configuration to branch.c
 . remote: add per-remote autosetupmerge and autosetuprebase configuration
 . introduce a struct tracking_config
 . branch: install_branch_config and struct tracking refactoring
 . config: allow false and true values for branch.autosetuprebase

Has been ejected from 'pu' for some time, expecting a reroll.
