+What's cooking in git.git (Mar 2009, #01; Tue, 03)
+--------------------------------------------------
+
+Here are the topics that have been cooking.  Commits prefixed with '-' are
+only in 'pu' while commits prefixed with '+' are in 'next'.  The ones
+marked with '.' do not appear in any of the branches, but I am still
+holding onto them.
+
+The topics list the commits in reverse chronological order.  The topics
+meant to be merged to the maintenance series have "maint-" in their names.
+
+The master branch is slightly past 1.6.2-rc2.  It's been a week and I
+think I can declare the final on this Wednesday, *if* I am not too mired
+by the day job, but I do not know what would happen yet.
+
+As an experiment, 'next' and 'pu' stayed open during this release freeze;
+new topics have been accepted.  I have to say that the experiment was a
+moderate success, and many topics in 'next' seem to be of fairly high
+quality already, which would mean that we will have a shorter cycle before
+1.6.3.

+ . clone: do not ignore --no-local option
+
+Jeff had a good suggestion for this series but it was tripped by
+a misfeature in parse_options().

+ - optimize compat/ memmem()
+ - diffcore-pickaxe: use memmem()

+ - fsck: three levels of validation
+ - verify-pack: add --quick
+ - verify_pack(): allow a quicker verification for a pack with

+
+J6t has a good point that if this had any value then medium level should
+replace the default.  I am tempted to actually dropping this as a failed
+experiment.

+[Stalled and may need help and prodding to go forward]
+
+* gb/gitweb-base (Sun Feb 15 10:18:36 2009 +0100) 1 commit
+ - gitweb: fix wrong base URL when non-root DirectoryIndex
+
+* ns/stash-keep (Thu Feb 12 06:25:14 2009 +0900) 1 commit
+ - stash: --keep option just saves
+
+Do we want to keep this one?
+
+* lh/submodule-tree-traversal (Sun Jan 25 01:52:06 2009 +0100) 1 commit
+ - archive.c: add support for --submodules[=(all|checkedout)]
+
+Discussion stalled on the submodule selection criteria.
+
+* 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
+
+This gives Porcelains (like gitweb) the information on the commit _before_
+the one that the final blame is laid on, which should save them one
+rev-parse to dig further.  The line number in the "previous" information
+may need refining, and sanity checking code for reference counting may
+need to be resurrected before this can move forward.
+
+I thought recent tig discussion may blow new life into it, but is this
+unneeded?  If so I'd rather revert it (or discard after 1.6.2).
+
+* db/foreign-scm (Sun Jan 11 15:12:10 2009 -0500) 3 commits
+ - Support fetching from foreign VCSes
+ - Add specification of git-vcs helpers
+ - Add "vcs" config option in remotes
+
+The "spec" did not seem quite well cooked yet, but in the longer term I
+think something like this to allow interoperating with other SCMs as if
+the other end is a native git repository is a very worthy goal.
+
+* cc/replace (Mon Feb 2 06:13:06 2009 +0100) 11 commits
+ - builtin-replace: use "usage_msg_opt" to give better error messages
+ - parse-options: add new function "usage_msg_opt"
+ - builtin-replace: teach "git replace" to actually replace
+ - Add new "git replace" command
+ - environment: add global variable to disable replacement
+ - mktag: call "check_sha1_signature" with the replacement sha1
+ - replace_object: add a test case
+ - object: call "check_sha1_signature" with the replacement sha1
+ - sha1_file: add a "read_sha1_file_repl" function
+ - replace_object: add mechanism to replace objects found in
+   "refs/replace/"
+ - refs: add a "for_each_replace_ref" function
+
+I think the code is much cleaner than the first round, but I am not
+convinced it is doing the right thing in the connectivity traverser.  
+Independent review sorely needed.
+
+* sc/gitweb-category (Fri Dec 12 00:45:12 2008 +0100) 3 commits
+ - gitweb: Optional grouping of projects by category
+ - gitweb: Split git_project_list_body in two functions
+ - gitweb: Modularized git_get_project_description to be more generic
+
+Design discussion between Jakub and Sebastien seems to have stalled, but
+Jakub seems to be taking this over.

+ - builtin-commit: shorten eye-sore overlong lines

+
+* jc/merge-convert (Mon Jan 26 16:45:01 2009 -0800) 1 commit
+ - git-merge-file: allow converting the results for the work tree
+
+This is a feature waiting for a user.  I do not need it in 1.6.2
+
+We did not give scripted Porcelains a way to say "this temporary file I am
+using for merging is for this path, so use the core.autocrlf and attributes
+rules for that final path".  Instead, merge-file simply wrote out the
+data in the canonical repository representation.
+
+rerere has the same issue, but it is a lot worse.  It reads the three
+files (preimage, postimage and thisimage) from the work tree in the work
+tree representation, merges them without converting them to the canonical
+representation first but inserts the conflict markers with the canonical
+representation and writes the resulting mess out.  It needs to be fixed to
+read with convert_to_git(), merge them while they are still in the
+canonical representation and possibly add conflict markers, and then write
+the results out after convert_to_working_tree().  It also needs to write
+in binary mode as well.
