What's cooking in git.git (Feb 2012, #01; Fri, 3)
--------------------------------------------------

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

Here are the repositories that have my integration branches:

With maint, master, next, pu, todo:

        git://git.kernel.org/pub/scm/git/git.git
        git://repo.or.cz/alt-git.git
        https://code.google.com/p/git-core/
        https://github.com/git/git

With only maint and master:

        git://git.sourceforge.jp/gitroot/git-core/git.git
        git://git-core.git.sourceforge.net/gitroot/git-core/git-core

With all the topics and integration branches:

        https://github.com/gitster/git

The preformatted documentation in HTML and man format are found in:

        git://git.kernel.org/pub/scm/git/git-{htmldocs,manpages}.git/
        git://repo.or.cz/git-{htmldocs,manpages}.git/

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

* nd/diffstat-gramnum (2012-02-03) 1 commit
 - Use correct grammar in diffstat summary line

The commands in the "git diff" family and "git apply --stat" that count
the number of files changed and the number of lines inserted/deleted have
been updated to match the output from "diffstat".  This also opens the
door to i18n this line.

Will merge to 'next'.

* jx/i18n-more-marking (2012-02-01) 2 commits
 - i18n: format_tracking_info "Your branch is behind" message
 - i18n: git-commit whence_s "merge/cherry-pick" message

Will merge to 'next'.

* jk/grep-binary-attribute (2012-02-02) 9 commits
 - grep: pre-load userdiff drivers when threaded
 - grep: load file data after checking binary-ness
 - grep: respect diff attributes for binary-ness
 - grep: cache userdiff_driver in grep_source
 - grep: drop grep_buffer's "name" parameter
 - convert git-grep to use grep_source interface
 - grep: refactor the concept of "grep source" into an object
 - grep: move sha1-reading mutex into low-level code
 - grep: make locking flag global

Fixes a longstanding bug that there was no way to tell "git grep" that a
path may look like text but it is not, which "git diff" can do using the
attributes system. Now "git grep" honors the same "binary" (or "-diff")
attribute.

Will merge to 'next'.

* jc/parse-date-raw (2012-02-03) 2 commits
 - parse_date(): '@' prefix forces git-timestamp
 - parse_date(): allow ancient git-timestamp

"rebase" and "commit --amend" failed to work on commits with ancient
timestamps near year 1970.

Waiting for comments.

* jk/git-dir-lookup (2012-02-02) 1 commit
 - standardize and improve lookup rules for external local repos

Will merge to 'next'.

* jk/prompt-fallback-to-tty (2012-02-03) 2 commits
 - prompt: fall back to terminal if askpass fails
 - prompt: clean up strbuf usage

The code to ask for password did not fall back to the terminal input when
GIT_ASKPASS is set but does not work (e.g. lack of X with GUI askpass
helper).

* jk/tests-write-script (2012-02-03) 2 commits
 - t0300: use write_script helper
 - tests: add write_script helper function

Will merge to 'next'.

* jn/gitweb-search-utf-8 (2012-02-03) 1 commit
 - gitweb: Allow UTF-8 encoded CGI query parameters and path_info

Search box in "gitweb" did not accept non-ASCII characters correctly.
Will merge to 'next'.

* jn/rpm-spec (2012-02-03) 1 commit
 - git.spec: Workaround localized messages not put in any RPM

Fix breakage in v1.7.9 Makefile; rpmbuild notices an unpackaged but
installed *.mo file and fails.

Will merge to 'next'.

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

* jc/pull-signed-tag (2012-01-23) 1 commit
  (merged to 'next' on 2012-01-23 at 4257553)
 + merge: use editor by default in interactive sessions

"git merge" in an interactive session learned to spawn the editor by
default to let the user edit the auto-generated merge message, to
encourage people to explain their merges better. Legacy scripts can
export MERGE_AUTOEDIT=no to retain the historical behaviour.

* tr/merge-edit-guidance (2012-01-31) 1 commit
  (merged to 'next' on 2012-01-31 at bb678f7)
 + merge: add instructions to the commit message when editing

"git merge" adds advice text to the commit log template when running
interactively.

--------------------------------------------------
[Stalled]

* jc/advise-push-default (2011-12-18) 1 commit
 - push: hint to use push.default=upstream when appropriate

Peff had a good suggestion outlining an updated code structure so that
somebody new can try to dip his or her toes in the development. Any
takers?

Waiting for a reroll.

* ss/git-svn-prompt-sans-terminal (2012-01-04) 3 commits
 - fixup! 15eaaf4
 - git-svn, perl/Git.pm: extend Git::prompt helper for querying users
 - perl/Git.pm: "prompt" helper to honor GIT_ASKPASS and SSH_ASKPASS

The bottom one has been replaced with a rewrite based on comments from
Ævar. The second one needs more work, both in perl/Git.pm and prompt.c, to
give precedence to tty over SSH_ASKPASS when terminal is available.

* nd/commit-ignore-i-t-a (2012-01-16) 2 commits
 - commit, write-tree: allow to ignore CE_INTENT_TO_ADD while writing trees
 - cache-tree: update API to take abitrary flags

May want to consider this as fixing an earlier UI mistake, and not as a
feature that devides the userbase.

--------------------------------------------------
[Cooking]

* fc/zsh-completion (2012-02-03) 3 commits
 - completion: simplify __gitcomp and __gitcomp_nl implementations
 - completion: use ls -1 instead of rolling a loop to do that ourselves
 - completion: work around zsh option propagation bug

Fix git subcommand completion for zsh (in contrib/completion).

Will merge to 'next'.

* jc/maint-request-pull-for-tag (2012-01-31) 1 commit
  (merged to 'next' on 2012-02-01 at 7649f18)
 + request-pull: explicitly ask tags/$name to be pulled

When asking for a tag to be pulled, "request-pull" shows the name of the
tag prefixed with "tags/"

* nd/find-pack-entry-recent-cache-invalidation (2012-02-01) 2 commits
  (merged to 'next' on 2012-02-01 at e26aed0)
 + find_pack_entry(): do not keep packed_git pointer locally
 + sha1_file.c: move the core logic of find_pack_entry() into fill_pack_entry()

* nd/pack-objects-parseopt (2012-02-01) 3 commits
 - pack-objects: convert to use parse_options()
 - pack-objects: remove bogus comment
 - pack-objects: do not accept "--index-version=version,"

Will merge to 'next'.

"pack-objects" learned use parse-options, losing custom command line
parsing code.

* bl/gitweb-project-filter (2012-02-01) 8 commits
  (merged to 'next' on 2012-02-01 at 2c96ce7)
 + gitweb: Make project search respect project_filter
 + gitweb: improve usability of projects search form
 + gitweb: place links to parent directories in page header
 + gitweb: show active project_filter in project_list page header
 + gitweb: limit links to alternate forms of project_list to active project_filter
 + gitweb: add project_filter to limit project list to a subdirectory
 + gitweb: prepare git_get_projects_list for use outside 'forks'.
 + gitweb: move hard coded .git suffix out of git_get_projects_list

"gitweb" allows intermediate entries in the directory hierarchy that leads
to a projects to be clicked, which in turn shows the list of projects
inside that directory.

* rt/completion-branch-edit-desc (2012-01-29) 1 commit
  (merged to 'next' on 2012-02-01 at 0627ebf)
 + completion: --edit-description option for git-branch

Originally merged to 'next' on 2012-01-31.
Will merge to 'master'.

"vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and support
incremental imports.

Will merge to 'next' through the tip and then to 'master' soon after.

* jc/split-blob (2012-01-24) 6 commits
 - chunked-object: streaming checkout
 - chunked-object: fallback checkout codepaths
 - bulk-checkin: support chunked-object encoding
 - bulk-checkin: allow the same data to be multiply hashed
 - new representation types in the packstream
 - varint-in-pack: refactor varint encoding/decoding

Not ready.

I finished the streaming checkout codepath, but as explained in 127b177
(bulk-checkin: support chunked-object encoding, 2011-11-30), these are
still early steps of a long and painful journey. At least pack-objects and
fsck need to learn the new encoding for the series to be usable locally,
and then index-pack/unpack-objects needs to learn it to be used remotely.

Given that I heard a lot of noise that people want large files, and that I
was asked by somebody at GitTogether'11 privately for an advice on how to
pay developers (not me) to help adding necessary support, I am somewhat
dissapointed that the original patch series that was sent almost two
months ago still remains here without much comments and updates from the
developer community. I even made the interface to the logic that decides
where to split chunks easily replaceable, and I deliberately made the
logic in the original patch extremely stupid to entice others, especially
the "bup" fanboys, to come up with a better logic, thinking that giving
people an easy target to shoot for, they may be encouraged to help
out. The plan is not working :-(.
