What's cooking in git.git (topics)

[Junio C Hamano <gitster@pobox.com>]

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.

It's been a while since the last issue of this series.  I've been
swamped, and haven't had a chance to spend enough time on reviewing and
accepting patches.

A rough timeline from now on.

 * Will merge the remaining topics already on 'next', and perhaps accept a
   handful minor topics that are not yet in.

 * Fixes of 'master' continues; 1.5.6-rc0 gets tagged (2008-05-21).

 * 1.5.6 Final (2008-06-08).

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

* bc/tag (Fri May 9 00:03:35 2008 -0500) 3 commits
 - ident.c: New function valid_ident for checking ident string
   formatting
 - Make mktag a builtin
 - mktag.c: adjust verify_tag parameters

I stopped looking at this after hitting an unappliable patch --- will need
to take a look at it again.

* js/config-cb (Wed May 14 18:46:53 2008 +0100) 1 commit
 - Provide git_config with a callback-data parameter

This needs to wait until most of the other things graduate for 1.5.6;
luckily, unlike the other "path-list" changes, misconversions is much
easier to catch for this change and I am not worried about it.

* ds/branch-auto-rebase (Sat May 10 15:36:29 2008 -0700) 1 commit
 + Allow tracking branches to set up rebase by default.

For 1.5.6.

* bc/repack (Wed May 14 01:33:53 2008 -0400) 5 commits
 + let pack-objects do the writing of unreachable objects as loose
   objects
 + add a force_object_loose() function
 + builtin-gc.c: deprecate --prune, it now really has no effect
 + git-gc: always use -A when manually repacking
 + repack: modify behavior of -A option to leave unreferenced objects
   unpacked

For 1.5.6.

* sp/ignorecase (Sun May 11 18:16:42 2008 +0200) 4 commits
 - t0050: Add test for case insensitive add
 - t0050: Set core.ignorecase case to activate case insensitivity
 - t0050: Test autodetect core.ignorecase
 - git-init: autodetect core.ignorecase

This unfortunately seems to break on natively case sensitive filesystems.

* ar/add-unreadable (Mon May 12 19:59:23 2008 +0200) 5 commits
 + Add a config option to ignore errors for git-add
 + Add a test for git-add --ignore-errors
 + Add --ignore-errors to git-add to allow it to skip files with read
   errors
 + Extend interface of add_files_to_cache to allow ignore indexing
   errors
 + Make the exit code of add_file_to_index actually useful

* jc/diff-words (Sun May 11 12:33:48 2008 -0700) 2 commits
 - diff --color-words: a bit of tweak
 - diff --color-words reimplementation


----------------------------------------------------------------

 + diff: a submodule not checked out is not modified
 + Add t7506 to test submodule related functions for git-status
 + t4027: test diff for submodule with empty directory

A submodule that is not checked out is not modified, but was mistaken as
being removed.  Thanks Ping for tests and fixes.

* cc/hooks-doc (Fri May 2 05:30:47 2008 +0200) 1 commit
 + Documentation: rename "hooks.txt" to "githooks.txt" and make it a

----------------------------------------------------------------
[Will merge to "master" soonish]

 + graph API: eliminate unnecessary indentation
 + log and rev-list: add --graph option
 + Add history graph API
 + revision API: split parent rewriting and parent printing options

Draw "tig 'g'" graph without tig ;-)

 + pack-objects: fix early eviction for max depth delta objects
 + pack-objects: allow for early delta deflating

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

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

Allows common ancestor negotiation for git-push to help people with shared
repository workflow in certain minority situations.  The lack of protocol
support has been bugging me for quite some time, and that was the reason I
did this.

This needs debugging.

* ap/svn (Mon May 12 17:09:49 2008 -0700) 4 commits
 + git-svn: add test for --add-author-from and --use-log-author
 + git-svn: add documentation for --add-author-from option.
 + git-svn: Add --add-author-from option.
 + git-svn: add documentation for --use-log-author option.

Some tweak for output might be needed, I dunno.

* sv/first-parent (Mon May 12 17:12:36 2008 +0200) 2 commits
 + revision.c: really honor --first-parent
 + Simplify and fix --first-parent implementation

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

* jc/blame (Wed Apr 2 22:17:53 2008 -0700) 5 commits
 + git-blame --reverse
 + builtin-blame.c: allow more than 16 parents
 + builtin-blame.c: move prepare_final() into a separate function.
 + rev-list --children
 + revision traversal: --children option

The blame that finds where each line in the original lines moved to.  This
may help a GSoC project that wants to gather statistical overview of the
history.  The final presentation may need tweaking (see the log message of
the tip commit on the series).

* js/rebase-i-sequencer (Sun Apr 27 02:55:50 2008 -0400) 17 commits
 + Use perl instead of tac
 + Fix t3404 assumption that `wc -l` does not use whitespace.
 + rebase -i: Use : in expr command instead of match.
 + rebase -i: update the implementation of 'mark' command
 + Add option --preserve-tags
 + Teach rebase interactive the tag command
 + Add option --first-parent
 + Do rebase with preserve merges with advanced TODO list
 + Select all lines with fake-editor
 + Unify the length of $SHORT* and the commits in the TODO list
 + Teach rebase interactive the merge command
 + Move redo merge code in a function
 + Teach rebase interactive the reset command
 + Teach rebase interactive the mark command
 + Move cleanup code into it's own function
 + Don't append default merge message to -m message
 + fake-editor: output TODO list if unchanged

This may complement the proposed "sequencer" GSoC project.  Dscho seems to
have quite a strong objection to the 'mark' syntax and mechanism being
unnecessarily complex.  Let's wait and see if a less complex but equally
expressive alternative materializes...

* ar/batch-cat (Wed Apr 23 15:17:47 2008 -0400) 5 commits
 - git-cat-file: Add --batch option
 - git-cat-file: Add --batch-check option
 - git-cat-file: Make option parsing a little more flexible
 - git-cat-file: Small refactor of cmd_cat_file
 - Add tests for git cat-file

I fixed up the problematic shell script in the first patch in the series
but later one introduced the same problematic constructs in another file,
at which point I gave up and discarded the rest.  At least it now passes
its own testsuite without breaking others.

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

* 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.

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

This needs to be held back, as it actually removes the support for
features that the main part of the series deprecates, until 1.6.0 or
later.

* pb/push (Mon Apr 28 11:32:12 2008 -0400) 1 commit
 + add special "matching refs" refspec

This first patch is a good enhancement without hurting any existing users.
We need a staged introduction of the second and later patches, and many
people including me did not agree the later ones in the series are
desirable.

* nd/dashless (Wed Nov 28 23:21:57 2007 +0700) 1 commit
 - Move all dashed-form commands to libexecdir

Scheduled for 1.6.0.

* jc/dashless (Sat Dec 1 22:09:22 2007 -0800) 2 commits
 - Prepare execv_git_cmd() for removal of builtins from the
   filesystem
 - git-shell: accept "git foo" form

We do not plan to remove git-foo form completely from the filesystem at
this point, but git-shell may need to be updated.

* jc/cherry-pick (Wed Feb 20 23:17:06 2008 -0800) 3 commits
 - WIP: rethink replay merge
 - Start using replay-tree merge in cherry-pick
 - revert/cherry-pick: start refactoring call to merge_recursive

This is meant to improve cherry-pick's behaviour when renames are
involved, by not using merge-recursive (whose d/f conflict resolution is
quite broken), but unfortunately has stalled for some time now.

* 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

Just my toy at this moment.
