+What's cooking in git.git (Sep 2009, #05; Wed, 23)
+--------------------------------------------------
+
+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 integration branches, but I am
+still holding onto them.
+
+In 1.7.0, we plan to correct handful of warts in the interfaces everybody
+agrees that they were mistakes.  The resulting system may not be strictly
+backward compatible.  Currently planeed changes are:
+
+ * refuse push to update the checked out branch in a non-bare repo by
+   default
+
+   Make "git push" into a repository to update the branch that is checked
+   out fail by default.  You can countermand this default by setting a
+   configuration variable in the receiving repository.
+
+   http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+ * refuse push to delete the current branch by default
+
+   Make "git push $there :$killed" to delete the branch that is pointed at
+   by its HEAD fail by default.  You can countermand this default by
+   setting a configuration variable in the receiving repository.
+
+   http://thread.gmane.org/gmane.comp.version-control.git/108862/focus=108936
+
+ * git-send-email won't make deep threads by default
+
+   Many people said that by default when sending more than 2 patches the
+   threading git-send-email makes by default is hard to read, and they
+   prefer the default be one cover letter and each patch as a direct
+   follow-up to the cover letter.  You can countermand this by setting a
+   configuration variable.
+
+   http://article.gmane.org/gmane.comp.version-control.git/109790
+
+ * git-status won't be "git-commit --dry-run" anymore
+
+   http://thread.gmane.org/gmane.comp.version-control.git/125989/focus=125993
+
+ * "git-diff -w --exit-code" will exit success if only differences it
+   found are whitespace changes that are stripped away from the output.
+
+   http://thread.gmane.org/gmane.comp.version-control.git/119731/focus=119751
+
+We are in pre-release feature freeze.  'next' will hold topics meant for
+1.6.6 and 1.7.0.
+
+Tonight's tip of 'master' is 1.6.5-rc2, and I'll disappear for about a
+week.  Hopefully when I come back in early October all the regressions are
+found and already squashed ;-)
+
+--------------------------------------------------
+[New Topics]
+
+* jc/fix-tree-walk (2009-09-14) 9 commits
+ - read-tree --debug-unpack
+ - unpack-trees.c: look ahead in the index
+ - unpack-trees.c: prepare for looking ahead in the index
+ - traverse_trees(): handle D/F conflict case sanely
+ - more D/F conflict tests
+ - tests: move convenience regexp to match object names to test-lib.sh
+ - unpack_callback(): use unpack_failed() consistently
+ - unpack-trees: typofix
+ - diff-lib.c: fix misleading comments on oneway_diff()
+
+This is my replacement for Linus's lt/maint-traverse-trees-fix patch.  It
+is not so much as a counter-proposal; I originally thought it might make
+sense to walk the index and drive the walker to return the entries from
+trees to match entries from the index, but I ended up doing pretty much
+what Linus outlined --- walk the trees, and have the index walker follow
+it.  It turned out that the index side also needed some hairy look-ahead,
+and I am only half satisfied with the current status of the series.
+
+To fix the resolve merge regression seen in t6035, git-merge-resolve needs
+to be rewritten not to use the one-path-at-a-time "git merge-index".
+
+* jp/fetch-tag-match (2009-09-17) 1 commit
+ - fetch: Speed up fetch by rewriting find_non_local_tags
+
+I did not have much energy left while dealing with the "fix-tree-walk"
+series, so I just queued this without reading nor thinking about it very
+much.  I personally liked my version that had far smaller number of lines
+changed (which means I can be fairly certain that it did not introduce any
+regression), but perhaps the majorly rewritten logic this patch gives us
+may be easier to follow and maintain.  We'll see.
+
+* jg/log-format-body-indent (2009-09-19) 1 commit
+ - [NEEDSWORK: tests] git-log --format: Add %B tag with %B(x) option
+
+* jl/submodule-add-noname (2009-09-22) 1 commit
+ - git submodule add: make the <path> parameter optional
+
+--------------------------------------------------
+[Stalled]
+
+* je/send-email-no-subject (2009-08-05) 1 commit
+  (merged to 'next' on 2009-08-30 at b6455c2)
+ + send-email: confirm on empty mail subjects
+
+The existing tests cover the positive case (i.e. as long as the user says
+"yes" to the "do you really want to send this message that lacks subject",
+the message is sent) of this feature, but the feature itself needs its own
+test to verify the negative case (i.e. does it correctly stop if the user
+says "no"?)
+
+* jh/cvs-helper (2009-08-18) 8 commits
+ - More fixes to the git-remote-cvs installation procedure
+ - Fix the Makefile-generated path to the git_remote_cvs package in git-remote-cvs
+ - Add simple selftests of git-remote-cvs functionality
+ - git-remote-cvs: Remote helper program for CVS repositories
+ - 2/2: Add Python support library for CVS remote helper
+ - 1/2: Add Python support library for CVS remote helper
+ - Basic build infrastructure for Python scripts
+ - Allow helpers to request marks for fast-import
+ (this branch uses db/vcs-helper-rest.)
+
+Builds on db/vcs-helper.  There is a re-roll planned.
+
+* ne/rev-cache (2009-09-07) 7 commits
+ - support for commit grafts, slight change to general mechanism
+ - support for path name caching in rev-cache
+ - full integration of rev-cache into git, completed test suite
+ - administrative functions for rev-cache, start of integration into git
+ - support for non-commit object caching in rev-cache
+ - basic revision cache system, no integration or features
+ - man page and technical discussion for rev-cache
+
+Tonight's 'pu' ships with this and this series seems to break a few
+tests.  I didn't debug.
+
+--------------------------------------------------
+[Cooking]
+
+* jc/maint-blank-at-eof (2009-09-15) 0 commits.
+ (this branch uses jc/maint-1.6.0-blank-at-eof.)
+
+The series does not have a commit of its own but is a preparation for
+merging the original jc/1.6.0-maint-blank-at-eof topic to 'maint' and then
+'master'.  It is a fix for longstanding bug and 1.6.5 will not contain
+this topic.
+
+* db/vcs-helper-rest (2009-09-03) 6 commits
+ - Allow helpers to report in "list" command that the ref is unchanged
+ - Add support for "import" helper command
+ - Add a config option for remotes to specify a foreign vcs
+ - Allow programs to not depend on remotes having urls
+ - Allow fetch to modify refs
+ - Use a function to determine whether a remote is valid
+ (this branch is used by jh/cvs-helper.)
+
+This holds the remainder of the db/vcs-helper topic that has already
+merged for 1.6.5.
+
+* jh/notes (2009-09-12) 13 commits
+ - Selftests verifying semantics when loading notes trees with various fanouts
+ - Teach the notes lookup code to parse notes trees with various fanout schemes
+ - notes.[ch] fixup: avoid old-style declaration
+ - Teach notes code to free its internal data structures on request.
+ - Add '%N'-format for pretty-printing commit notes
+ - Add flags to get_commit_notes() to control the format of the note string
+ - t3302-notes-index-expensive: Speed up create_repo()
+ - fast-import: Add support for importing commit notes
+ - Teach "-m <msg>" and "-F <file>" to "git notes edit"
+ - Add an expensive test for git-notes
+ - Speed up git notes lookup
+ - Add a script to edit/inspect notes
+ - Introduce commit notes
+ (this branch uses sr/gfi-options.)
+
+Rerolled and queued.
+
+* jn/gitweb-show-size (2009-09-07) 1 commit
+ - gitweb: Add 'show-sizes' feature to show blob sizes in tree view
+
+* lt/maint-traverse-trees-fix (2009-09-06) 1 commit.
+ . Prepare 'traverse_trees()' for D/F conflict lookahead
+
+Ejected from 'pu' (see jc/fix-tree-walk above).
+
+* jc/maint-1.6.0-blank-at-eof (2009-09-14) 15 commits.
+  (merged to 'next' on 2009-09-15 at 9cbfa00)
+ + diff -B: colour whitespace errors
+ + diff.c: emit_add_line() takes only the rest of the line
+ + diff.c: split emit_line() from the first char and the rest of the line
+ + diff.c: shuffling code around
+ + diff --whitespace: fix blank lines at end
+  (merged to 'next' on 2009-09-07 at 165dc3c)
+ + core.whitespace: split trailing-space into blank-at-{eol,eof}
+ + diff --color: color blank-at-eof
+ + diff --whitespace=warn/error: fix blank-at-eof check
+ + diff --whitespace=warn/error: obey blank-at-eof
+ + diff.c: the builtin_diff() deals with only two-file comparison
+ + apply --whitespace: warn blank but not necessarily empty lines at EOF
+ + apply --whitespace=warn/error: diagnose blank at EOF
+ + apply.c: split check_whitespace() into two
+ + apply --whitespace=fix: detect new blank lines at eof correctly
+ + apply --whitespace=fix: fix handling of blank lines at the eof
+ (this branch is used by jc/maint-blank-at-eof.)
+
+This is a fix for an ancient bug (or inconsistent set of features); the
+topic is based on an ancient codebase and is designed to be merged
+upwards.  jc/maint-blank-at-eof serves that purpose.
+
+Will not be in 1.6.5.
+
+* jn/gitweb-blame (2009-09-01) 5 commits
+ - gitweb: Minify gitweb.js if JSMIN is defined

+[For 1.7.0]
+
+* jk/1.7.0-status (2009-09-05) 5 commits
+ - docs: note that status configuration affects only long format
+  (merged to 'next' on 2009-09-07 at 8a7c563)
+ + commit: support alternate status formats
+ + status: add --porcelain output format
+ + status: refactor format option parsing
+ + status: refactor short-mode printing to its own function
+ (this branch uses jc/1.7.0-status.)
+
+Gives the --short output format to post 1.7.0 "git commit --dry-run" that
+is similar to that of post 1.7.0 "git status".
+
+* jc/1.7.0-status (2009-09-05) 4 commits
+  (merged to 'next' on 2009-09-06 at 19d4beb)
+ + status: typo fix in usage
+  (merged to 'next' on 2009-08-22 at b3507bb)
+ + git status: not "commit --dry-run" anymore
+ + git stat -s: short status output
+ + git stat: the beginning of "status that is not a dry-run of commit"
+ (this branch is used by jk/1.7.0-status.)
+
+With this, "git status" is no longer "git commit --dry-run".
+
+* jc/1.7.0-send-email-no-thread-default (2009-08-22) 1 commit
+  (merged to 'next' on 2009-08-22 at 5106de8)

+  (merged to 'next' on 2009-08-02 at 9c08420)
+ + diff: Rename QUIET internal option to QUICK
+ + diff: change semantics of "ignore whitespace" options
+
+This changes exit code from "git diff --ignore-whitespace" and friends
+when there is no actual output.  It is a backward incompatible change, but
+we could argue that it is a bugfix.
+
+* jc/1.7.0-push-safety (2009-02-09) 2 commits
+  (merged to 'next' on 2009-08-02 at 38b82fe)
