What's cooking in git.git (May 2011, #06; Fri, 13)
--------------------------------------------------

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

I am somewhat frustrated that I so almost no reviews on gitweb
patches. Does this mean nobody is interested in viewing the projects
on gitweb? How can we improve this lack of review bandwidth situation?

The main part of this cycle is expected to run thru May, aiming for a
feature freeze in early June.

We are about to finish the week #3 of this cycle.

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

 + t1507: avoid "${parameter<op>'word'}" inside double-quotes

* jh/dirstat-lines (2011-04-29) 8 commits
  (merged to 'next' on 2011-04-29 at a302674)
 + Mark dirstat error messages for translation
 + Improve error handling when parsing dirstat parameters
 + New --dirstat=lines mode, doing dirstat analysis based on diffstat
 + Allow specifying --dirstat cut-off percentage as a floating point number
 + Add config variable for specifying default --dirstat behavior
 + Refactor --dirstat parsing; deprecate --cumulative and --dirstat-by-file
 + Make --dirstat=0 output directories that contribute < 0.1% of changes
 + Add several testcases for --dirstat and friends

* jn/setup-revisions-glob-and-friends-passthru (2011-04-21) 2 commits
  (merged to 'next' on 2011-04-28 at 6006cc4)
 + revisions: allow --glob and friends in parse_options-enabled commands
 + revisions: split out handle_revision_pseudo_opt function

* js/maint-1.6.6-send-pack-stateless-rpc-deadlock-fix (2011-05-05) 2 commits
 + send-pack: unbreak push over stateless rpc
 + send-pack: avoid deadlock when pack-object dies early
 (this branch is used by js/maint-send-pack-stateless-rpc-deadlock-fix.)

* js/maint-send-pack-stateless-rpc-deadlock-fix (2011-05-05) 2 commits
  (merged to 'next' on 2011-05-05 at 3f4ffb9)
 + Merge branch 'js/maint-1.6.6-send-pack-stateless-rpc-deadlock-fix' into js/maint-send-pack-stateless-rpc-deadlock-fix
  (merged to 'next' on 2011-04-28 at db7e04a)
 + Merge branch 'js/maint-1.6.6-send-pack-stateless-rpc-deadlock-fix' into js/maint-send-pack-stateless-rpc-deadlock-fix
 (this branch uses js/maint-1.6.6-send-pack-stateless-rpc-deadlock-fix.)

* rr/rerere-libify-clear-gc (2011-05-08) 1 commit
  (merged to 'next' on 2011-05-11 at b1d8c88)
 + rerere: libify rerere_clear() and rerere_gc()

This is pure code movement.  Changing them to suit the need of other
callers can be built on it as separate patches.

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

* jc/maint-1.6.6-pathspec-stdin-and-cmdline (2011-05-11) 1 commit
 + setup_revisions(): take pathspec from command line and --stdin correctly
 (this branch is used by jc/magic-pathspec, jc/maint-1.7.4-pathspec-stdin-and-cmdline and jc/maint-pathspec-stdin-and-cmdline.)

* jc/maint-1.7.4-pathspec-stdin-and-cmdline (2011-05-11) 1 commit
 - Merge branch 'jc/maint-1.6.6-pathspec-stdin-and-cmdline'
 (this branch uses jc/maint-1.6.6-pathspec-stdin-and-cmdline; is tangled with jc/magic-pathspec and jc/maint-pathspec-stdin-and-cmdline.)

* jc/maint-pathspec-stdin-and-cmdline (2011-05-11) 2 commits
 - Merge branch 'jc/maint-1.7.4-pathspec-stdin-and-cmdline'
 - Merge branch 'jc/maint-1.6.6-pathspec-stdin-and-cmdline'
 (this branch uses jc/maint-1.6.6-pathspec-stdin-and-cmdline; is tangled with jc/magic-pathspec and jc/maint-1.7.4-pathspec-stdin-and-cmdline.)

These are to fix an ancient bug where feeding "git log --stdin path" with
an input that also has additional pathspec corrupted memory.

* jl/read-tree-m-dry-run (2011-05-11) 1 commit
 - Teach read-tree the -n|--dry-run option

Looked good. We _might_ want to make -n simply ignore -u, though.

* jc/streaming (2011-05-12) 5 commits
 - write_entry(): use streaming API for writing working tree files
 - stream: a streaming interface to read from the object store
 - sha1_object_info_extended(): expose a bit more information from object-info
 - write_entry(): separate two helper functions out
 - packed_object_info_detail(): do not return a string
 (this branch uses jc/convert.)

The counterpart to jc/bigfile to cover the write-out codepath. This does
not yet have "read directly from pack or loose object without slurping the
whole thing in memory" yet, which is still work in progress.

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

* mg/diff-stat-count (2011-05-03) 2 commits
 - diff-options.txt: describe --stat-{width,name-width,count}
 - diff: introduce --stat-count to limit the stat lines

There was a miscounting spotted.  Need another round.

* jn/gitweb-js (2011-04-28) 13 commits
 - gitweb: Make JavaScript ability to adjust timezones configurable
 - gitweb.js: Add UI for selecting common timezone to display dates
 - gitweb: JavaScript ability to adjust time based on timezone
 - gitweb: Unify the way long timestamp is displayed
 - gitweb: Refactor generating of long dates into format_timestamp_html
 - gitweb.js: Provide getElementsByClassName method (if it not exists)
 - gitweb.js: Introduce code to handle cookies from JavaScript
 - gitweb.js: Extract and improve datetime handling
 - gitweb.js: Provide default values for padding in padLeftStr and padLeft
 - gitweb.js: Update and improve comments in JavaScript files
 - gitweb: Split JavaScript for maintability, combining on build
 - Remove gitweb/gitweb.cgi and other legacy targets from main Makefile
 - git-instaweb: Simplify build dependency on gitweb

Rerolled.  Waiting for comments.

* jn/ctags-more (2011-04-29) 3 commits
 - gitweb: Optional grouping of projects by category
 - gitweb: Modularized git_get_project_description to be more generic
 - gitweb: Split git_project_list_body in two functions

Waiting for comments.

* jc/require-work-tree-exists (2011-05-08) 1 commit
 - require-work-tree wants more than what its name says

Make "git pull" run from a random place work as long as GIT_DIR and
GIT_WORK_TREE are set up correctly.  I am not absolutely sure if that
is a sane use case, though. May drop.

* jc/add-delete-default (2011-04-27) 1 commit
 - git add: notice removal of tracked paths by default

* jk/maint-merge-rename-create (2011-03-25) 3 commits
 - merge: turn on rewrite detection
 - merge: handle renames with replacement content
 - t3030: fix accidental success in symlink rename

Peff wanted to reroll this.

* jc/index-pack (2011-02-27) 5 commits
 - index-pack --verify: read anomalous offsets from v2 idx file
 - write_idx_file: need_large_offset() helper function
 - index-pack: --verify
 - write_idx_file: introduce a struct to hold idx customization options
 - index-pack: group the delta-base array entries also by type

Still a WIP. Need to put histogram output into index-pack --verify to
really kill verify-pack.

* jc/dotdot-is-parent-directory (2011-05-04) 1 commit
 - specifying ranges: we did not mean to make ".." an empty set

Updated documentation, but I do not feel a strong enough annoyance to push
this forward. May drop.

* jk/tag-contains (2010-07-05) 4 commits
 - Why is "git tag --contains" so slow?
 - default core.clockskew variable to one day
 - limit "contains" traversals based on commit timestamp
 - tag: speed up --contains calculation

The idea of the bottom one is probably Ok, except that the use of object
flags needs to be rethought, or at least the helper needs to be moved to
builtin/tag.c to make it clear that it should not be used outside the
current usage context.

* jc/advice-about-to-lose-commit (2011-05-06) 1 commit
 - checkout: honor advice.detachedHead when reattaching to a branch

Needs to tighten the advice to only govern the generic How-to part.

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

* jc/bigfile (2011-05-12) 3 commits
 - Bigfile: teach "git add" to send a large file straight to a pack
 - index_fd(): split into two helper functions
 - index_fd(): turn write_object and format_check arguments into one flag

This covers the entry point for a big file to the system. Other parts that
need to know about them are the exit point (i.e. write_entry()), packing
and repacking (as long as bigfilethreshold is sane this should work),
diffs and status (avoid slurping large binary in core only to do nothing,
which we already should), and transport (receive-pack/fetch-pack call
either unpack-objects or index-pack, which still want to hold the full
object in-core and need to be fixed).

* jc/convert (2011-05-09) 4 commits
 - convert: make it harder to screw up adding a conversion attribute
 - convert: make it safer to add conversion attributes
 - convert: give saner names to crlf/eol variables, types and functions
 - convert: rename the "eol" global variable to "core_eol"
 (this branch is used by jc/streaming.)

Just a clean-up.
Will merge to "next" by the end of week #3.

* jk/blame-line-porcelain (2011-05-09) 3 commits
 - blame: add --line-porcelain output format
 - blame: refactor porcelain output
 - add tests for various blame formats

* ms/tagname-does-not-begin-with-dash (2011-05-10) 1 commit
 - tag: disallow '-' as tag name

Will merge to "next" by the end of week #3.

* fc/completion-zsh (2011-05-10) 1 commit
 + git-completion: fix regression in zsh support
 (this branch is used by sg/completion-updates.)

* nd/sparse-co-fix (2011-05-10) 2 commits
 - sparse checkout: do not eagerly decide the fate for whole directory
 - t1011: fix sparse-checkout initialization and add new file

* kk/maint-prefix-in-config-mak (2011-05-09) 3 commits
  (merged to 'next' on 2011-05-09 at 267a3aa)
 + Honor $(prefix) set in config.mak* when defining ETC_GIT*
 + Revert "Honor $(prefix) set in config.mak* when defining ETC_GIT* and sysconfdir"
  (merged to 'next' on 2011-05-02 at c747ba3)
 + Honor $(prefix) set in config.mak* when defining ETC_GIT* and sysconfdir

One revert and replace the whole thing from J6t. The end result looked
reasonable.

Will merge to "master" by the end of week #4.

* ci/commit--interactive-atomic (2011-05-10) 6 commits
  (merged to 'next' on 2011-05-11 at 7f36fd8)
 + Test atomic git-commit --interactive
 + Add commit to list of config.singlekey commands
 + Add support for -p/--patch to git-commit
 + Allow git commit --interactive with paths
 + t7501.8: feed a meaningful command
 + Use a temporary index for git commit --interactive

Will merge to "master" by the end of week #4.

  (merged to 'next' on 2011-05-02 at 0fd443a)

 (this branch uses fc/completion-zsh.)

This reverts the "local words only on bash" thingy and uses the
workaround blessed by zsh folks instead.

Will merge to "master" by the end of week #4.

  (merged to 'next' on 2011-05-12 at 656c8b5)

 (this branch uses jc/maint-1.6.6-pathspec-stdin-and-cmdline; is tangled with jc/maint-1.7.4-pathspec-stdin-and-cmdline and jc/maint-pathspec-stdin-and-cmdline.)

This seems to need more time to mature than I expected.
