What's cooking in git.git (topics)

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

The topics list the commits in reverse chronological order.

I'd like to get post-release fixes to 'maint' first, tag 1.5.4.1 and merge that to 'master', and then start merging things from 'next' to 'master'.

My wish is to have small but short release cycle for 1.5.5 and leave bigger ones cooking for 1.6.0.

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

* sp/safecrlf (Wed Feb 6 12:25:58 2008 +0100) 1 commit
 + safecrlf: Add mechanism to warn about irreversible crlf
   conversions

 + fix config reading in tests
 + allow suppressing of global and system config

* lh/gitdir (Mon Feb 4 21:59:21 2008 +0100) 4 commits
 - git-submodule: prepare for the .git-file
 - Add tests for .git file
 - Document the .git-file
 - Add platform-independent .git "symlink"

Seems to have funny interaction with Jeff King's test script updates.

* pb/prepare-commit-msg (Tue Feb 5 08:04:18 2008 +0100) 4 commits
 + git-commit: add a prepare-commit-msg hook

---------------------------------------------------------------- [Requests for Comments]

* db/send-email-omit-cc (Tue Dec 25 19:56:29 2007 -0800) 1 commit
 + git-send-email: Generalize auto-cc recipient mechanism.

This came after 1.5.4-rc cycle started and was placed on hold. I do not recall if there was any objection to it.

* jc/gitignore-ends-with-slash (Thu Jan 31 20:23:25 2008 -0800) 2 commits
 + gitignore: lazily find dtype
 + gitignore(5): Allow "foo/" in ignore list to match directory "foo"

This is redone after we had discussion on the list to properly make "foo/" match only with directories and "foo" with both files and directories without unnecessary lstat(2) calls.

* jc/apply-whitespace (Tue Jan 15 00:59:05 2008 -0800) 13 commits
 + core.whitespace: cr-at-eol
 + git-apply --whitespace=fix: fix whitespace fuzz introduced by
   previous run
 + builtin-apply.c: pass ws_rule down to match_fragment()
 + builtin-apply.c: move copy_wsfix() function a bit higher.
 + builtin-apply.c: do not feed copy_wsfix() leading '+'
 + builtin-apply.c: simplify calling site to apply_line()
 + builtin-apply.c: clean-up apply_one_fragment()
 + builtin-apply.c: mark common context lines in lineinfo structure.
 + builtin-apply.c: optimize match_beginning/end processing a bit.
 + builtin-apply.c: make it more line oriented
 + builtin-apply.c: push match-beginning/end logic down
 + builtin-apply.c: restructure "offset" matching
 + builtin-apply.c: refactor small part that matches context

* jc/sha1-lookup (Sun Dec 30 03:13:27 2007 -0800) 2 commits
 - sha1-lookup: make selection of 'middle' less aggressive
 - sha1-lookup: more memory efficient search in sorted list of SHA-1

Micro-optimization whose real world benefit is not proven.

* jc/rename (Tue Jan 29 20:54:56 2008 -0800) 1 commit
 - Optimize rename detection for a huge diff

Micro-optimization whose real world benefit is not proven.

---------------------------------------------------------------- [Will merge to 'master' after 1.5.4.1]

* ph/describe-match (Mon Dec 24 12:18:22 2007 +0100) 2 commits
 + git-name-rev: add a --(no-)undefined option.
 + git-describe: Add a --match option to limit considered tags.

* lt/in-core-index (Tue Jan 22 23:01:13 2008 -0800) 9 commits
 + lazy index hashing
 + Create pathname-based hash-table lookup into index
 + read-cache.c: introduce is_racy_timestamp() helper
 + read-cache.c: fix a couple more CE_REMOVE conversion
 + Also use unpack_trees() in do_diff_cache()
 + Make run_diff_index() use unpack_trees(), not read_tree()
 + Avoid running lstat(2) on the same cache entry.
 + index: be careful when handling long names
 + Make on-disk index representation separate from in-core one

This is about reducing number of lstat(2) calls during complex operations, and optimizing "do we have this in the index" queries. Most likely this will be the first series to be merged to 'master'.

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

* jc/setup (Sun Feb 3 23:59:17 2008 -0800) 4 commits
 + builtin-mv: minimum fix to avoid losing files
 + git-add: adjust to the get_pathspec() changes.
 + Make blame accept absolute paths
 + setup: sanitize absolute and funny paths in get_pathspec()

* jc/error-message-in-cherry-pick (Thu Jan 10 22:49:35 2008 -0800) 1 commit
 + Make error messages from cherry-pick/revert more sensible

Björn Steinbrink reported and then tested this. Is queued in 'next' but will push it out to 'master' after 1.5.4.1.

* jc/submittingpatches (Sun Feb 3 17:02:28 2008 -0800) 3 commits
 + Documentation/SubmittingPatches: What's Acked-by and Tested-by?
 + Documentation/SubmittingPatches: discuss first then submit
 + Documentation/SubmittingPatches: Instruct how to use [PATCH]
   Subject header

These I think are sensible but they did not see much discussion, so they are parked here for now.

* cc/browser (Sat Feb 2 07:32:56 2008 +0100) 4 commits
 + instaweb: use 'git-web--browse' to launch browser.
 + Rename 'git-help--browse.sh' to 'git-web--browse.sh'.
 + help--browse: add '--config' option to check a config option for a
   browser.
 + help: make 'git-help--browse' usable outside 'git-help'.

Christian Couder consolidated the logic to pick user's favorite browser between instaweb and help.

* mw/send-email (Sun Feb 3 19:53:58 2008 -0500) 3 commits
 + git-send-email: Better handling of EOF
 + git-send-email: SIG{TERM,INT} handlers
 + git-send-email: ssh/login style password requests

For 'master' post 1.5.4.1.

* db/no-separate-ls-remote-connection (Mon Feb 4 13:26:23 2008 -0500) 1 commit
 + Reduce the number of connects when fetching

Looked reasonably clean and correct. Will park in 'next' just in case, but I think this is ready for 'master' post 1.5.4.1.

* bd/qsort (Tue Feb 5 15:10:44 2008 -0600) 1 commit
 + compat: Add simplified merge sort implementation from glibc

More reasonable qsort(3) than Microsoft by Brian Downing; I already did the "de-gcc-ism" pointed out on the list but Brian said he would reroll the patch, so I've parked it in 'pu' for now. If Brian is Ok with the version here, we could move it to 'next'.

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

* js/reflog-delete (Fri Jan 4 19:11:37 2008 -0600) 2 commits
 + builtin-reflog.c: fix typo that accesses an unset variable
 + Teach "git reflog" a subcommand to delete single entries

There was a patch that uses this to implement "git-stash drop", which I didn't queue, as the command name and the UI was undecided yet.

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

Scheduled for 1.6.0. I am not sure if we should merge this to 'next' before 1.5.5. Most active people will be on 'next' and if we have this there, the resulting 1.5.5 release might end up having issues that come from differences this one introduces.

---------------------------------------------------------------- [temporarily excluded]

* bf/remote-head (Sun Dec 23 20:52:32 2007 -0500) 1 commit
 . git-remote: make add -f guess HEAD, as clone does

I might have carefully looked at this in the past but I do not recall if there were issues. Need re-reviewing and help from the list is appreciated.

* ab/pserver (Fri Dec 14 04:08:51 2007 +0000) 1 commit
 . Authentication support for pserver

This needs careful security audit and a fix to its password database format. Plaintext in .git/config is not acceptable.

* jc/cherry-pick (Mon Dec 24 00:51:01 2007 -0800) 4 commits
 . PARK: Start using replay-tree merge in cherry-pick
 . revert/cherry-pick: start refactoring call to merge_recursive
 . expose a helper function peel_to_type().
 . merge-recursive: split low-level merge functions out.

Meant to avoid merge_recursive() during cherry-pick and revert, so that D/F conflicts can be redone right, but I got busy and this has unfortunately stalled.

* 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/diff-relative (Thu Dec 6 09:48:32 2007 -0800) 1 commit
 . Make "diff" Porcelain output paths as relative to subdirectory.

* jc/git-symref (Tue Dec 11 16:42:46 2007 -0800) 1 commit
 . PARK: show-symref protocol extension.
