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.

I ran out of time while re-reviewing the stalled topics to
decide what to do with them, and many of them are left out of
'pu' branch for tonight, even though I haven't dropped them
entirely from my repository yet.

A funny thing is, 'pu' passes most of the testsuite thanks to
this temporary droppage.  The tip of 'pu' hasn't passed the
tests for quite some time.

New tests for svn-info seem to be failing in my private
repository at k.org; I haven't tried to look into it yet.

[Will cook further in 'next' and then merge to 'master' soon]

* jc/move-gitk (Sat Nov 17 10:51:16 2007 -0800) 1 commit
 + Move gitk to its own subdirectory

I have a phoney Makefile under the subdirectory for gitk, but
hopefully with the next pull from Paulus I can replace it with
the real thing, along with the i18n stuff.

* cc/bisect (Tue Nov 20 06:39:53 2007 +0100) 7 commits
 + Bisect reset: do nothing when not bisecting.
 + Bisect: use "$GIT_DIR/BISECT_NAMES" to check if we are bisecting.
 + Bisect visualize: use "for-each-ref" to list all good refs.
 + git-bisect: modernize branch shuffling hack
 + git-bisect: use update-ref to mark good/bad commits
 + git-bisect: war on "sed"
 + Bisect reset: remove bisect refs that may have been packed.

Will merge by the weekend (if I can find time, that is).

* mh/rebase-skip-hard (Thu Nov 8 08:03:06 2007 +0100) 1 commit
 + Do git reset --hard HEAD when using git rebase --skip

After seeing a conflicted rebase, you may decide to skip that
patch but then you would need "git reset --hard" before saying
"git rebase --skip".  This teaches "git rebase --skip" to
automatically discard the conflicted rebase for you.

Will merge by the weekend.

* tt/help (Sun Nov 11 19:57:57 2007 -0500) 2 commits
 + Remove hint to use "git help -a"
 + Make the list of common commands more exclusive

Some people on the list may find the exact list of commands
somewhat debatable.  We can fine-tune that in-tree ('pu' does
not count as "in-tree").

* js/mingw-fallouts (Sat Nov 17 23:09:28 2007 +0100) 13 commits
 + fetch-pack: Prepare for a side-band demultiplexer in a thread.
 + rehabilitate some t5302 tests on 32-bit off_t machines
 + Allow ETC_GITCONFIG to be a relative path.
 + Introduce git_etc_gitconfig() that encapsulates access of
   ETC_GITCONFIG.
 + Allow a relative builtin template directory.
 + Close files opened by lock_file() before unlinking.
 + builtin run_command: do not exit with -1.
 + Move #include <sys/select.h> and <sys/ioctl.h> to git-compat-
   util.h.
 + Use is_absolute_path() in sha1_file.c.
 + Skip t3902-quoted.sh if the file system does not support funny
   names.
 + t5302-pack-index: Skip tests of 64-bit offsets if necessary.
 + t7501-commit.sh: Not all seds understand option -i
 + t5300-pack-object.sh: Split the big verify-pack test into smaller
   parts.

A set of good general clean-up patches.

* sb/clean (Wed Nov 14 23:00:54 2007 -0600) 3 commits
 + Teach git clean to use setup_standard_excludes()
 + git-clean: Fix error message if clean.requireForce is not set.
 + Make git-clean a builtin

* jc/spht (Fri Nov 2 17:46:55 2007 -0700) 3 commits
 + core.whitespace: add test for diff whitespace error highlighting
 + git-diff: complain about >=8 consecutive spaces in initial indent
 + War on whitespace: first, a bit of retreat.

Teaching "git apply --whitespace=[warn|strip]" to honor the same
configuration would be a good addition, but this could go to
'master' as is.

* jk/send-pack (Tue Nov 20 06:18:01 2007 -0500) 29 commits
 + send-pack: cluster ref status reporting
 + send-pack: fix "everything up-to-date" message
 + send-pack: tighten remote error reporting
 + make "find_ref_by_name" a public function
 + Fix warning about bitfield in struct ref
 + send-pack: assign remote errors to each ref
 + send-pack: check ref->status before updating tracking refs
 + send-pack: track errors for each ref
 + Merge branch 'aw/mirror-push' into jk/send-pack
 + Merge branch 'ar/send-pack-remote-track' into jk/send-pack
 + Merge branch 'db/remote-builtin' into jk/send-pack
 + git-push: add documentation for the newly added --mirror mode
 + Add tests for git push'es mirror mode
 + Update the tracking references only if they were succesfully
   updated on remote
 + Add a test checking if send-pack updated local tracking branches
   correctly
 + git-push: plumb in --mirror mode
 + Teach send-pack a mirror mode
 + Merge master into aw/mirror-push
 + Merge branch 'jk/terse-push' into aw/mirror-push
 + send-pack: segfault fix on forced push
 + Reteach builtin-ls-remote to understand remotes
 + send-pack: require --verbose to show update of tracking refs
 + receive-pack: don't mention successful updates
 + more terse push output
 + Build in ls-remote
 + Build-in send-pack, with an API for other programs to call.
 + Use built-in send-pack.
 + Build-in peek-remote, using transport infrastructure.
 + Miscellaneous const changes and utilities

Various improvements on status reporting and error handling by
send-pack, and implementation of "mirror" pushing.

----------------------------------------------------------------
[Actively cooking]

* kh/commit (Thu Nov 22 16:21:49 2007 -0800) 23 commits
 + Add a few more tests for git-commit
 + builtin-commit: Include the diff in the commit message when
   verbose.
 + builtin-commit: fix partial-commit support
 + Fix add_files_to_cache() to take pathspec, not user specified list
   of files
 + Export three helper functions from ls-files
 + builtin-commit: run commit-msg hook with correct message file
 + builtin-commit: do not color status output shown in the message
   template
 + file_exists(): dangling symlinks do exist
 + Replace "runstatus" with "status" in the tests
 + t7501-commit: Add test for git commit <file> with dirty index.
 + builtin-commit: Clean up an unused variable and a debug fprintf().
 + Call refresh_cache() when updating the user index for --only
   commits.
 + builtin-commit: Add newline when showing which commit was created
 + builtin-commit: resurrect behavior for multiple -m options
 + builtin-commit --s: add a newline if the last line was not a S-o-b
 + builtin-commit: fix --signoff
 + git status: show relative paths when run in a subdirectory
 + builtin-commit: Refresh cache after adding files.
 + builtin-commit: fix reflog message generation
 + launch_editor(): read the file, even when EDITOR=:
 + Port git commit to C.
 + Export launch_editor() and make it accept ':' as a no-op editor.
 + Add testcase for amending and fixing author in git commit.

Although I found the fd shuffling somewhat distasteful, overall
the series seems reasonably stable so it is in 'next'.

* cr/tag-options (Thu Nov 22 23:16:51 2007 -0800) 2 commits
 + builtin-tag: accept and process multiple -m just like git-commit
 + Make builtin-tag.c use parse_options.

The handling of multiple -m options are made consistent with
what git-commit does; i.e. they are concatenated as separate
paragraphs.

* wc/add-i (Thu Nov 22 01:47:13 2007 -0800) 3 commits
 + git-add -i: allow multiple selection in patch subcommand
 + Add path-limiting to git-add--interactive
 + Teach builtin-add to pass multiple paths to git-add--interactive

This still does not have the "directly invoke 'patch' subcommand
and exit after the interaction without coming back to the menu"
part.

* sp/refspec-match (Sun Nov 11 15:01:48 2007 +0100) 4 commits
 + refactor fetch's ref matching to use refname_match()
 + push: use same rules as git-rev-parse to resolve refspecs
 + add refname_match()
 + push: support pushing HEAD to real branch name

These are the uncontroversial bits from the series.

The "--matching" patch was dropped; I do not know what will
happen to the "--current" thing.  I'd prefer to postpone the
discussion until jk/send-pack topic stabilizes and graduates.

* jc/branch-contains (Sun Nov 18 22:22:00 2007 -0800) 3 commits
 + git-branch --contains: doc and test
 + git-branch --contains=commit
 + parse-options: Allow to hide options from the default usage.

Contains Pierre's "hidable options with --help-all" patch.

----------------------------------------------------------------
[Approaching 'next']

----------------------------------------------------------------
[Others]

* jc/maint-format-patch-encoding (Fri Nov 2 17:55:31 2007 -0700) 2 commits
 - test format-patch -s: make sure MIME content type is shown as
   needed
 - format-patch -s: add MIME encoding header if signer's name
   requires so

This is to apply to 'maint' later; the equivalent fix is already
in 'master'.

* lt/maint-rev-list-gitlink (Sun Nov 11 23:35:23 2007 +0000) 1 commit
 - Fix rev-list when showing objects involving submodules

This is to apply to 'maint' later; the equivalent fix is already
in 'next' and will be merged to 'master' soon.

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

* jc/cherry-pick (Tue Nov 13 12:38:51 2007 -0800) 1 commit
 - revert/cherry-pick: start refactoring call to merge_recursive

* jc/nu (Sun Oct 14 22:07:34 2007 -0700) 3 commits
 - merge-nu: a new merge backend without using unpack_trees()
 - read_tree: take an explicit index structure
 - gcc 4.2.1 -Werror -Wall -ansi -pedantic -std=c99: minimum fix

The second one could probably be used to replace the use of
path-list in the tip commit on the kh/commit series.

* dz/color-addi (Sat Nov 10 18:03:44 2007 -0600) 3 commits
 - Added diff hunk coloring to git-add--interactive
 - Let git-add--interactive read colors from .gitconfig
 - Added basic color support to git add --interactive

There were many good suggestions by Jeff to the updated series;
hopefully we can replace these three with it.

* nd/maint-work-tree-fix (Sat Nov 3 20:18:06 2007 +0700) 1 commit
 + Add missing inside_work_tree setting in setup_git_directory_gently

There was an additional patch, which still had issues Dscho
pointed out.  Waiting for refinements.

* js/reflog-delete (Wed Oct 17 02:50:45 2007 +0100) 1 commit
 + Teach "git reflog" a subcommand to delete single entries

* jc/pathspec (Thu Sep 13 13:38:19 2007 -0700) 3 commits
 - pathspec_can_match(): move it from builtin-ls-tree.c to tree.c
 - ls-tree.c: refactor show_recursive() and rename it.
 - tree-diff.c: split out a function to match a single pattern.

* ss/dirty-rebase (Thu Nov 1 22:30:24 2007 +0100) 3 commits
 . Make git-svn rebase --dirty pass along --dirty to git-rebase.
 . Implement --dirty for git-rebase--interactive.
 . Introduce --dirty option to git-rebase, allowing you to start from
   a dirty state.

This seems to be optimized for the --dirty case too much.  I'd
prefer an implementation that make rebases without --dirty to
pay no penalty (if that is possible, otherwise "as little as
possible").

* jk/rename (Tue Oct 30 00:24:42 2007 -0400) 3 commits
 . handle renames using similarity engine
 . introduce generic similarity library
 . change hash table calling conventions

This was an attempt to use different strategy to speed up
similarity computation, but does not work quite well as is.
