+
+What's cooking in git.git (Dec 2009, #02; Sat, 05)
+--------------------------------------------------
+
+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 planned 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
+
+ * "git diff -w/-b" won't even produce "diff --git" header when all changes
+ are about whitespaces.
+
+ http://thread.gmane.org/gmane.comp.version-control.git/133256
+
+--------------------------------------------------
+[New Topics]
+
+Note: Ilari's vcs-helper series hasn't been queued yet, as its first round
+generated a healthy amount of discussion and he made it clear that the
+second round is being prepared, addressing the comments given on the list.
+Hopefully trivial coding style issues in the first round will also be
+fixed (e.g. keyword "if" lacked a SP after it before opening parenthesis
+of the condition) in the second round.
+
+* jn/maint-pull-rebase-error-message (2009-11-27) 1 commit.
+ (merged to 'next' on 2009-12-03 at 2ced03c)
+ + pull: clarify advice for the unconfigured error case
+
+Replaces old 'jn/rfc-pull-rebase-error-message' topic.
+
+* fc/opt-quiet-gc-reset (2009-12-02) 1 commit
+ - General --quiet improvements
+
+* mv/commit-date (2009-12-03) 2 commits
+ - Document date formats accepted by parse_date()
+ - builtin-commit: add --date option
+
+* mh/rebase-fixup (2009-12-05) 4 commits
+ - [squash to Add a command "fix"] Avoid "\(alternatives\|choices\)" in sed script
+ - Add a command "fix" to rebase --interactive.
+ - t3404: set a couple more tags in the original repository
+ - t3404: Better document the original repository layout

+
+* je/send-email-no-subject (2009-08-05) 1 commit.
+ (merged to 'next' on 2009-10-11 at 1b99c56)
+ + 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"?)
+
+* jc/checkout-merge-base (2009-11-20) 2 commits
+ - "rebase --onto A...B" replays history on the merge base between A and B
+ - "checkout A...B" switches to the merge base between A and B
+
+I've been using the first one for a while myself but do not see many users
+want this (yet); the new feature is not urgent anyway.
+
+* jh/notes (2009-12-02) 11 commits
+ - Refactor notes concatenation into a flexible interface for combining notes
+ - Notes API: Allow multiple concurrent notes trees with new struct notes_tree
+ - Notes API: for_each_note(): Traverse the entire notes tree with a callback
+ - Notes API: get_note(): Return the note annotating the given object
+ - Notes API: add_note(): Add note objects to the internal notes tree structure
+ - Notes API: init_notes(): Initialize the notes tree from the given notes ref
+ - Notes API: get_commit_notes() -> format_note() + remove the commit restriction
+ - Minor style fixes to notes.c
+ - Add more testcases to test fast-import of notes
+ - Rename t9301 to t9350, to make room for more fast-import tests
+ - fast-import: Proper notes tree manipulation
+
+Rerolled (waiting for Acks).
+
+* tr/maint-merge-ours-clarification (2009-11-15) 1 commit
+ (merged to 'next' on 2009-11-21 at fadaf7b)
+ + rebase: refuse to rebase with -s ours
+
+I do not think we reached a concensus for solving conflicts between "give
+them rope" and "protect users from clearly meaningless combinations". The
+author obviously is for the latter (and I am inclined to agree); Dscho
+seems to think otherwise.
+
+* jc/fix-tree-walk (2009-10-22) 8 commits
+ (merged to 'next' on 2009-10-22 at 10c0c8f)
+ + Revert failed attempt since 353c5ee
+ + read-tree --debug-unpack
+ (merged to 'next' on 2009-10-11 at 0b058e2)
+ + unpack-trees.c: look ahead in the index
+ + unpack-trees.c: prepare for looking ahead in the index
+ + Aggressive three-way merge: fix D/F case
+ + 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
+
+This has some stupid bugs and reverted from 'next' until I can fix it, but
+the "temporarily" turned out to be very loooong. Sigh. We won't have a
+proper fix in 1.6.6.
+
+* jc/grep-full-tree (2009-11-24) 1 commit.
+ - grep: --full-tree
+
+The interaction with this option and pathspecs need to be worked out
+better. I _think_ "grep --full-tree -e pattern -- '*.h'" should find from
+all the header files in the tree, for example.
+
+--------------------------------------------------
+[Cooking]
+
+* sr/gfi-options (2009-12-04) 7 commits
+ - fast-import: add (non-)relative-marks feature
+ - fast-import: allow for multiple --import-marks= arguments
+ - fast-import: test the new option command
+ - fast-import: add option command
+ - fast-import: add feature command
+ - fast-import: put marks reading in its own function
+ - fast-import: put option parsing code in separate functions
+
+Rerolled.
+
+* ap/merge-backend-opts (2008-07-18) 6 commits
+ - Document that merge strategies can now take their own options
+ - Extend merge-subtree tests to test -Xsubtree=dir.
+ - Make "subtree" part more orthogonal to the rest of merge-recursive.
+ - Teach git-pull to pass -X<option> to git-merge
+ - git merge -X<option>
+ - git-merge-file --ours, --theirs
+
+"git pull" patch needs sq-then-eval fix to protect it from $IFS
+but otherwise seemed good.
+
+* mo/bin-wrappers (2009-12-02) 3 commits
+ - INSTALL: document a simpler way to run uninstalled builds
+ - run test suite without dashed git-commands in PATH
+ - build dashless "bin-wrappers" directory similar to installed bindir
+
+Rerolled.
+
+* tr/http-updates (2009-12-01) 3 commits
+ - Allow curl to rewind the RPC read buffer
+ - Add an option for using any HTTP authentication scheme, not only basic
+ - http: maintain curl sessions
+
+There was a discussion on a better structure not to require rewinding in
+the first place? I didn't follow it closely...
+
+* jc/diff-whitespace-prepare (2009-11-28) 2 commits
+ - diff: flip the default diff.bwoutputonly to true
+ - diff: optionally allow traditional "-b/-w affects only output" semantics
+ (this branch uses gb/1.7.0-diff-whitespace-only-output and jc/1.7.0-diff-whitespace-only-status; is used by jc/1.7.0-diff-whitespace-prepare.)
+
+This is to redo the two -b/-w semantic changes to prepare the migration of
+existing users before 1.7.0 happens.
+
+* sr/vcs-helper (2009-12-04) 13 commits
+ (merged to 'next' on 2009-12-03 at e45b562)
+ + builtin-push: don't access freed transport->url
+ (merged to 'next' on 2009-11-27 at 83268ab)
+ + Add Python support library for remote helpers
+ + Basic build infrastructure for Python scripts
+ + Allow helpers to report in "list" command that the ref is unchanged
+ + Fix various memory leaks in transport-helper.c
+ + Allow helper to map private ref names into normal names
+ + Add support for "import" helper command
+ + Allow specifying the remote helper in the url
+ + Add a config option for remotes to specify a foreign vcs
+ + Allow fetch to modify refs
+ + Use a function to determine whether a remote is valid
+ + Allow programs to not depend on remotes having urls
+ + Fix memory leak in helper method for disconnect
+
+Should be among the first to graduate after 1.6.6 final.
+
+* tr/reset-checkout-patch (2009-11-19) 1 commit.
+ (merged to 'next' on 2009-11-22 at b224950)
+ + {checkout,reset} -p: make patch direction configurable
+
+I do not particularly like a configuration like this that changes the
+behaviour of a command in a drastic way---it will make helping others
+much harder.
+
+* nd/sparse (2009-11-25) 20 commits.
+ (merged to 'next' on 2009-11-25 at 71380f5)
+ + tests: rename duplicate t1009
+ (merged to 'next' on 2009-11-23 at f712a41)
+ + sparse checkout: inhibit empty worktree
+ + Add tests for sparse checkout
+ + read-tree: add --no-sparse-checkout to disable sparse checkout support
+ + unpack-trees(): ignore worktree check outside checkout area
+ + unpack_trees(): apply $GIT_DIR/info/sparse-checkout to the final index
+ + unpack-trees(): "enable" sparse checkout and load $GIT_DIR/info/sparse-checkout
+ + unpack-trees.c: generalize verify_* functions
+ + unpack-trees(): add CE_WT_REMOVE to remove on worktree alone
+ + Introduce "sparse checkout"
+ + dir.c: export excluded_1() and add_excludes_from_file_1()
+ + excluded_1(): support exclude files in index
+ + unpack-trees(): carry skip-worktree bit over in merged_entry()
+ + Read .gitignore from index if it is skip-worktree
+ + Avoid writing to buffer in add_excludes_from_file_1()
+ + Teach Git to respect skip-worktree bit (writing part)
+ + Teach Git to respect skip-worktree bit (reading part)
+ + Introduce "skip-worktree" bit in index, teach Git to get/set this bit
+ + Add test-index-version
+ + update-index: refactor mark_valid() in preparation for new options
+
+There were some test glitches reported and at least one test seems to
+be broken in the sense that it is not testing what it is trying to.
+Fix-up expected.

+--------------------------------------------------
+[For 1.7.0]
+
+* jk/1.7.0-status (2009-12-05) 9 commits.
+ (merged to 'next' on 2009-12-05 at 44dcefd)
+ + status -s: obey color.status
+ + builtin-commit: refactor short-status code into wt-status.c
+ (merged to 'next' on 2009-11-27 at 91691ec)
+ + t7508-status.sh: Add tests for status -s
+ + status -s: respect the status.relativePaths option
+ (merged to 'next' on 2009-11-21 at 884bb56)
+ + docs: note that status configuration affects only long format
+ (merged to 'next' on 2009-10-11 at 65c8513)
+ + 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".
+
+Immediately after 1.6.6 while rebuilding 'next', we may want to reorder a
+few commits at the tip, as "docs: affects only long format" describes a
+limitation that will disappear soon.
+
+* jc/1.7.0-status (2009-09-05) 4 commits.
+ (merged to 'next' on 2009-10-11 at 9558627)
+ + status: typo fix in usage
+ + 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 2009-10-11 at 043acdf)
+ + send-email: make --no-chain-reply-to the default
+
+As the title says.
+
+* jc/1.7.0-push-safety (2009-02-09) 2 commits.
+ (merged to 'next' on 2009-10-11 at 81b8128)
+ + Refuse deleting the current branch via push
+ + Refuse updating the current branch in a non-bare repository via push
+
+* jc/1.7.0-diff-whitespace-only-status (2009-08-30) 4 commits.
+ (merged to 'next' on 2009-10-11 at 546c74d)
+ + diff.c: fix typoes in comments
+ + Make test case number unique
+ + diff: Rename QUIET internal option to QUICK
+ + diff: change semantics of "ignore whitespace" options
+ (this branch is used by jc/1.7.0-diff-whitespace-prepare and jc/diff-whitespace-prepare.)
+
+This changes exit code from "git diff --ignore-whitespace" and friends
+when there is no actual output. It is a backward incompatible change,
+and jc/diff-whitespace-prepare topic is meant to ease the transition.
+
+* gb/1.7.0-diff-whitespace-only-output (2009-11-19) 1 commit
+ (merged to 'next' on 2009-11-21 at 3375bf4)
+ + No diff -b/-w output for all-whitespace changes
+ (this branch is used by jc/1.7.0-diff-whitespace-prepare and jc/diff-whitespace-prepare.)
+
+Likewise but for the output of "diff --git" headers.
+
+* jc/1.7.0-diff-whitespace-prepare (2009-11-28) 2 commits
+ - diff: disable diff.bwoutputonly warning
+ - diff: flip the diff.bwoutputonly default to false
+ (this branch uses gb/1.7.0-diff-whitespace-only-output, jc/1.7.0-diff-whitespace-only-status and jc/diff-whitespace-prepare.)
+
+And this is to actually flip the default and eventually remove the warning.
+
+* ns/1.7.0-send-email-no-chain-reply-to (2009-08-22) 1 commit
+ - send-email: make --no-chain-reply-to the default
+
+And this is to actually flip the default in 1.7.0.

+[Reverted from 'next']
+
+* jc/botched-maint-cygwin-count-objects (2009-11-24) 2 commits.
+ (merged to 'next' on 2009-11-25 at 8aa62a0)
+ + Revert "ST_BLOCKS_COUNTS_IN_BLKSIZE to say on-disk size is (st_blksize * st_blocks)"
+ (merged to 'next' on 2009-11-22 at 4ba5880)
+ + ST_BLOCKS_COUNTS_IN_BLKSIZE to say on-disk size is (st_blksize * st_blocks)
+
+This is a revert of the tip one I merged prematurely to 'next'. The real
+fix from Ramsay is already in 'master'.
+
+* ks/precompute-completion (2009-11-15) 4 commits.
+ (merged to 'next' on 2009-11-15 at 23cdb96)
+ + Revert ks/precompute-completion series
+ (merged to 'next' on 2009-10-28 at cd5177f)
+ + completion: ignore custom merge strategies when pre-generating
+ (merged to 'next' on 2009-10-22 at f46a28a)
+ + bug: precomputed completion includes scripts sources
+ (merged to 'next' on 2009-10-14 at adf722a)
+ + Speedup bash completion loading
+
+Reverted out of 'next', to be replaced with jn/faster-completion-startup
+topic.

+[I have been too busy to purge these]
+
+* jn/rfc-pull-rebase-error-message (2009-11-12) 1 commit
+ . git-pull.sh --rebase: overhaul error handling when no candidates are found
+
+Replaced.
+
+* jc/log-tz (2009-03-03) 1 commit.
+ - Allow --date=local --date=other-format to work as expected
+
+Maybe some people care about this. I dunno.

+* jc/1.7.0-no-commit-no-ff-2 (2009-10-22) 1 commit.
+ . git-merge: forbid fast-forward and up-to-date when --no-commit is given
+
+This makes "git merge --no-commit" fail when it results in fast-forward or
+up-to-date. It appears nobody wants to have this, so I dropped it.
+
+* ne/rev-cache (2009-10-19) 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
+
+The author indicated that there is another round coming. Does not seem to
+pass the tests when merged to 'pu', so it has been ejected for now.
+
+* pb/gitweb-no-project-list (2009-11-06) 3 commits.
+ . gitweb: Polish the content tags support
+ . gitweb: Support for no project list on gitweb front page
+ . gitweb: Refactor project list routines
+
+I picked these up but didn't queue as Warthog9's comments made certain
+amount of sense to me.
