What's cooking in git.git (Sep 2008, #01; Sat, 06)
--------------------------------------------------

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

The topics list the commits in reverse chronological order.  The topics
meant to be merged to the maintenance series have "maint-" in their names.

----------------------------------------------------------------
[Stalled -- Needs Action to Proceed (or to be dropped)]

* bd/blame (Thu Aug 21 18:22:01 2008 -0500) 5 commits
 - Use xdiff caching to improve git blame performance
 - Allow xdiff machinery to cache hash results for a file
 - Always initialize xpparam_t to 0
 - Bypass textual patch generation and parsing in git blame
 - Allow alternate "low-level" emit function from xdl_diff

Réne had good comments on how the callback should be structured.

* kb/am-directory (Fri Aug 29 15:27:50 2008 -0700) 1 commit
 - git-am: Pass the --directory option through to git-apply

----------------------------------------------------------------
[Will be merged to "master" soon]

* jc/hide-cr-in-diff-from-less (Wed Aug 27 19:48:01 2008 -0700) 1 commit
 + diff: Help "less" hide ^M from the output

* jc/maint-checkout-fix (Fri Aug 29 13:40:36 2008 -0700) 1 commit
 + checkout: do not check out unmerged higher stages randomly

This is the same one as the bottom of "better conflict resolution" series;
it is a bugfix meant to be applied on 'maint'.

* jc/cc-ld-dynpath (Sat Aug 16 15:01:23 2008 +0200) 2 commits
 + configure: auto detect dynamic library path switches
 + Makefile: Allow CC_LD_DYNPATH to be overriden

I decided to push this forward; it might break minority configurations,
but it appears nobody pays attention until it actually hurts, so let's see
what happens when this hits 'master'.

* ar/autospell (Sun Aug 31 15:54:58 2008 +0200) 2 commits
 + Add help.autocorrect to enable/disable autocorrecting
 + git wrapper: DWIM mistyped commands

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

* tr/rev-list-reverse (Mon Sep 1 00:31:37 2008 +0200) 2 commits
 + t6013: replace use of 'tac' with equivalent Perl
 + rev-list: fix --reverse interaction with --parents

* jc/better-conflict-resolution (Thu Sep 4 23:48:48 2008 +0200) 16 commits
 + Fix AsciiDoc errors in merge documentation
 + git-merge documentation: describe how conflict is presented
 + checkout --conflict=<style>: recreate merge in a non-default style
 + checkout -m: recreate merge when checking out of unmerged index
 + Merge branch 'jc/maint-checkout-fix' into 'jc/better-conflict-
   resolution'
 + git-merge-recursive: learn to honor merge.conflictstyle
 + merge.conflictstyle: choose between "merge" and "diff3 -m" styles
 + rerere: understand "diff3 -m" style conflicts with the original
 + rerere.c: use symbolic constants to keep track of parsing states
 + xmerge.c: "diff3 -m" style clips merge reduction level to EAGER or
   less
 + xmerge.c: minimum readability fixups
 + xdiff-merge: optionally show conflicts in "diff3 -m" style
 + xdl_fill_merge_buffer(): separate out a too deeply nested function
 + checkout --ours/--theirs: allow checking out one side of a
   conflicting merge
 + checkout -f: allow ignoring unmerged paths when checking out of
   the index
 + checkout: do not check out unmerged higher stages randomly

* lt/time-reject-fractional-seconds (Sat Aug 16 21:25:40 2008 -0700) 1 commit
 + date/time: do not get confused by fractional seconds

* jc/maint-name-hash-clear (Sat Aug 23 13:05:10 2008 -0700) 1 commit
 + discard_cache: reset lazy name_hash bit

I spotted this by accident while working on something unrelated.

When a program calls discard_cache() to read the index again, we do not
properly re-initialize the name_hash structure that is used by the case
insensitivitly logic.  This _might_ improve issues people may be having on
case insensitive filesystems.  I dunno.

* jc/add-ita (Thu Aug 21 01:44:53 2008 -0700) 1 commit
 + git-add --intent-to-add (-N)

Teaches "git add" to record only the intent to add a path later.
I rerolled this without the fake empty blob object.

* cc/bisect (Sat Sep 6 07:27:03 2008 +0200) 3 commits
 + bisect: remove "checkout_done" variable used when checking merge
   bases
 + bisect: only check merge bases when needed
 + bisect: test merge base if good rev is not an ancestor of bad rev

* mv/merge-recursive (Sat Sep 6 18:29:49 2008 +0200) 11 commits
 + builtin-merge: release the lockfile in try_merge_strategy()
 + merge-recursive: get rid of virtual_id
 + merge-recursive: move current_{file,directory}_set to struct
   merge_options
 + merge-recursive: move the global obuf to struct merge_options
 + merge-recursive: get rid of the index_only global variable
 + merge-recursive: move call_depth to struct merge_options
 + cherry-pick/revert: make direct internal call to merge_tree()
 + builtin-merge: avoid run_command_v_opt() for recursive and subtree
 + merge-recursive: introduce merge_options
 + merge-recursive.c: Add more generic merge_recursive_generic()
 + Split out merge_recursive() to merge-recursive.c

* jc/diff-prefix (Mon Aug 18 20:08:09 2008 -0700) 1 commit
 + diff: vary default prefix depending on what are compared

As some people may have noticed, I've been running with this one when
sending out "How about this" patches to the discussion threads.

* jc/post-simplify (Fri Aug 15 01:34:51 2008 -0700) 2 commits
 - revision --simplify-merges: incremental simplification
 - revision --simplify-merges: prepare for incremental simplification

I started making this incremental but the progress is not so great.

----------------------------------------------------------------
[On Hold]

* dk/emacs (Tue Aug 26 22:24:40 2008 -0500) 2 commits
 - Teach git.el to mark/unmark files by regexp
 - git.el: Diff only file at point by default

These are still queued but Alexandre had improvement requests so these
will likely be dropped.

* jc/stripspace (Sun Mar 9 00:30:35 2008 -0800) 6 commits
 - git-am --forge: add Signed-off-by: line for the author
 - git-am: clean-up Signed-off-by: lines
 - stripspace: add --log-clean option to clean up signed-off-by:
   lines
 - stripspace: use parse_options()
 - Add "git am -s" test
 - git-am: refactor code to add signed-off-by line for the committer

The one at second from the tip needs reworking.

* jc/send-pack-tell-me-more (Thu Mar 20 00:44:11 2008 -0700) 1 commit
 - "git push": tellme-more protocol extension

* jc/merge-whitespace (Sun Feb 24 23:29:36 2008 -0800) 1 commit
 - WIP: start teaching the --whitespace=fix to merge machinery

* jc/blame (Wed Jun 4 22:58:40 2008 -0700) 2 commits
 - blame: show "previous" information in --porcelain/--incremental
   format
 - git-blame: refactor code to emit "porcelain format" output

* sg/merge-options (Sun Apr 6 03:23:47 2008 +0200) 1 commit
 + merge: remove deprecated summary and diffstat options and config
   variables

This was previously in "will be in master soon" category, but it turns out
that the synonyms to the ones this one deletes are fairly new invention
that happend in 1.5.6 timeframe, and we cannot do this just yet.  Perhaps
in 1.7.0, but with the loud whining about moving git-foo out of $PATH we
have been hearing, it might not be a bad idea to drop this.

* jk/renamelimit (Sat May 3 13:58:42 2008 -0700) 1 commit
 - diff: enable "too large a rename" warning when -M/-C is explicitly
   asked for

This would be the right thing to do for command line use, but gitk will be
hit due to tcl/tk's limitation, so I am holding this back for now.
