What's cooking in git.git (Apr 2013, #09; Fri, 26)
--------------------------------------------------

Here are the topics that have been cooking.  Commits prefixed with
'-' are only in 'pu' (proposed updates) while commits prefixed with
'+' are in 'next'.

The release candidate preview 1.8.3-rc0 has been tagged. I'd like to
see people focus on catching and fixing last minute regressions and
incompleteness in the topics that have already in 'master' for the
upcoming release. New topics that are not relevant for the goal to
release a regression-free and complete 1.8.3 may not be queued even
on 'pu' until final to reduce hassles on integration testing (I do
not mean that it is forbidden to work on and discussing new topics
on the list. It is just the patches won't be considered as formal
submission and they won't hit 'pu').

As to the topics still cooking on 'next', I unfortunately do not see
anything that I feel comfortable merging for 1.8.3; but I am open to
suggestions.

You can find the changes described here in the integration branches
of the repositories listed at

    http://git-blame.blogspot.com/p/git-public-repositories.html

--------------------------------------------------
[Graduated to "master"]

 Further updates to remote-hg (in contrib/).


* jc/add-ignore-removal (2013-04-22) 2 commits
  (merged to 'next' on 2013-04-24 at c85c5a7)
 + git add: rephrase -A/--no-all warning
 + git add: --ignore-removal is a better named --no-all
 (this branch is used by jc/add-2.0-ignore-removal.)

 Introduce "--ignore-removal" as a synonym to "--no-all" for "git
 add", and improve the 2.0 migration warning with it.


* jk/remote-helper-with-signed-tags (2013-04-15) 3 commits
  (merged to 'next' on 2013-04-21 at 0231d45)
 + transport-helper: add 'signed-tags' capability
 + transport-helper: pass --signed-tags=warn-strip to fast-export
 + fast-export: add --signed-tags=warn-strip mode

 Allows remote-helpers to declare they can handle signed tags, and
 issue a warning when using those that don't.


* jn/glossary-revision (2013-04-21) 1 commit
  (merged to 'next' on 2013-04-24 at 70efbe7)
 + glossary: a revision is just a commit

 The wording for "revision" in the glossary wanted to say it refers
 to "commit (noun) as a concept" but it was badly phrased.

 This may need further updates to hint that in contexts where it is
 clear, the word may refer to an object name, not necessarily a
 commit. But the patch as-is is already an improvement.


* ph/rebase-original (2013-04-23) 1 commit
  (merged to 'next' on 2013-04-24 at c643dcd)
 + rebase: find orig_head unambiguously


* rr/shortlog-doc (2013-04-22) 8 commits
  (merged to 'next' on 2013-04-25 at a95a3fc)
 + builtin/shortlog.c: make usage string consistent with log
 + builtin/log.c: make usage string consistent with doc
 + git-shortlog.txt: make SYNOPSIS match log, update OPTIONS
 + git-log.txt: rewrite note on why "--" may be required
 + git-log.txt: generalize <since>..<until>
 + git-log.txt: order OPTIONS properly; move <since>..<until>
 + revisions.txt: clarify the .. and ... syntax
 + git-shortlog.txt: remove (-h|--help) from OPTIONS

 Update documentation for "log" and "shortlog".


* th/bisect-skipped-log (2013-04-23) 1 commit
  (merged to 'next' on 2013-04-25 at 1de189b)
 + bisect: Log possibly bad, skipped commits at bisection end

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

* kb/full-history-compute-treesame-carefully (2013-04-24) 2 commits
 - t6012: update test for tweaked full-history traversal
 - Make --full-history consider more merges


* tr/remote-tighten-commandline-parsing (2013-04-24) 3 commits
 - remote: 'show' and 'prune' can take more than one remote
 - remote: check for superfluous arguments in 'git remote add'
 - remote: add a test for extra arguments, according to docs

 Will merge to 'next'.


* zk/prompt-rebase-step (2013-04-25) 1 commit
  (merged to 'next' on 2013-04-25 at a8264bf)
 + bash-prompt.sh: show where rebase is at when stopped


* rr/pp-user-info-without-extra-allocation (2013-04-25) 3 commits
 - pretty: remove intermediate strbufs from pp_user_info()
 - pretty: simplify output line length calculation in pp_user_info()
 - pretty: simplify input line length calculation in pp_user_info()

 Will merge to 'next'.

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

* jc/format-patch (2013-04-22) 2 commits
 - format-patch: --inline-single
 - format-patch: rename "no_inline" field

 A new option to send a single patch to the standard output to be
 appended at the bottom of a message.  I personally have no need for
 this, but it was easy enough to cobble together.  Tests, docs and
 stripping out more MIMEy stuff are left as exercises to interested
 parties.

 Not ready for inclusion.


* jk/gitweb-utf8 (2013-04-08) 4 commits
 - gitweb: Fix broken blob action parameters on blob/commitdiff pages
 - gitweb: Don't append ';js=(0|1)' to external links
 - gitweb: Make feed title valid utf8
 - gitweb: Fix utf8 encoding for blob_plain, blobdiff_plain, commitdiff_plain, and patch

 Various fixes to gitweb.

 Waiting for a reroll after a review.


* jk/commit-info-slab (2013-04-19) 3 commits
 - commit-slab: introduce a macro to define a slab for new type
 - commit-slab: avoid large realloc
 - commit: allow associating auxiliary info on-demand
 (this branch is used by jc/show-branch.)

 Technology demonstration to show a way we could use unbound number
 of flag bits on commit objects.


* jn/config-ignore-inaccessible (2013-04-15) 1 commit
 - config: allow inaccessible configuration under $HOME

 When $HOME is misconfigured to point at an unreadable directory, we
 used to complain and die. This loosens the check.

 I do not think we agreed that this is a good idea, though.

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

* jh/checkout-auto-tracking (2013-04-21) 8 commits
  (merged to 'next' on 2013-04-22 at 2356700)
 + glossary: Update and rephrase the definition of a remote-tracking branch
 + branch.c: Validate tracking branches with refspecs instead of refs/remotes/*
 + t9114.2: Don't use --track option against "svn-remote"-tracking branches
 + t7201.24: Add refspec to keep --track working
 + t3200.39: tracking setup should fail if there is no matching refspec.
 + checkout: Use remote refspecs when DWIMming tracking branches
 + t2024: Show failure to use refspec when DWIMming remote branch names
 + t2024: Add tests verifying current DWIM behavior of 'git checkout <branch>'

 Updates "git checkout foo" that DWIMs the intended "upstream" and
 turns it into "git checkout -t -b foo remotes/origin/foo" to
 correctly take existing remote definitions into account.  The
 remote "origin" may be what uniquely map its own branch to
 remotes/some/where/foo but that some/where may not be "origin".

 Will cook in 'next'.


* mg/more-textconv (2013-04-23) 7 commits
 - git grep: honor textconv by default
 - grep: honor --textconv for the case rev:path
 - grep: allow to use textconv filters
 - t7008: demonstrate behavior of grep with textconv
 - cat-file: do not die on --textconv without textconv filters
 - show: honor --textconv for blobs
 - t4030: demonstrate behavior of show with textconv

 Rerolled. I am not sure if I like "show <blob>" and "grep" that use
 textconv by default, though.


* mh/multimail (2013-04-21) 1 commit
 - git-multimail: a replacement for post-receive-email

 Waiting for comments.


* jc/prune-all (2013-04-25) 4 commits
  (merged to 'next' on 2013-04-26 at 97a7387)
 + prune: introduce OPT_EXPIRY_DATE() and use it
  (merged to 'next' on 2013-04-22 at b00ccf6)
 + api-parse-options.txt: document "no-" for non-boolean options
 + git-gc.txt, git-reflog.txt: document new expiry options
 + date.c: add parse_expiry_date()
 (this branch is tangled with mh/packed-refs-various.)

 We used the approxidate() parser for "--expire=<timestamp>" options
 of various commands, but it is better to treat --expire=all and
 --expire=now a bit more specially than using the current timestamp.
 Update "git gc" and "git reflog" with a new parsing function for
 expiry dates.

 Will cook in 'next'.


* as/check-ignore (2013-04-11) 5 commits
  (merged to 'next' on 2013-04-21 at 7515aa8)
 + Documentation: add caveats about I/O buffering for check-{attr,ignore}
 + check-ignore: allow incremental streaming of queries via --stdin
 + check-ignore: move setup into cmd_check_ignore()
 + check-ignore: add -n / --non-matching option
 + t0008: remove duplicated test fixture data

 Enhance "check-ignore" (1.8.2 update) to work more like "check-attr"
 over bidi-pipes.

 Will wait for a follow-up.
 $gmane/222235

 The test in the second from the tip needs to be updated.

 + api-parse-options.txt: document "no-" for non-boolean options
 + git-gc.txt, git-reflog.txt: document new expiry options
 + date.c: add parse_expiry_date()
 (this branch is tangled with jc/prune-all.)

 Updates reading and updating packed-refs file, correcting corner
 case bugs.


* fc/transport-helper-error-reporting (2013-04-25) 10 commits
  (merged to 'next' on 2013-04-25 at 3358f1a)
 + t5801: "VAR=VAL shell_func args" is forbidden
  (merged to 'next' on 2013-04-22 at 5ba6467)
 + transport-helper: update remote helper namespace
 + transport-helper: trivial code shuffle

 Update transport helper to report errors and maintain ref hierarchy
 used to keep track of remote helper state better.

 J6t reports that the update to t5801 breaks on Windows by the
 remote-testgit that is written in bash, and Windows port of bash
 does not have process substitution so remote-testgit is unusable
 there.


* jk/submodule-subdirectory-ok (2013-04-24) 3 commits
  (merged to 'next' on 2013-04-24 at 6306b29)
 + submodule: fix quoting in relative_path()
  (merged to 'next' on 2013-04-22 at f211e25)
 + submodule: drop the top-level requirement
 + rev-parse: add --prefix option

 Allow various subcommands of "git submodule" to be run not from the
 top of the working tree of the superproject.

 Will cook in 'next'.

 + submodule.c: duplicate real_path's return value
  (merged to 'next' on 2013-04-19 at 45ae3c9)
 + rm: delete .gitmodules entry of submodules removed from the work tree
 + Teach mv to update the path entry in .gitmodules for moved submodules
 + Teach mv to move submodules using a gitfile
 + Teach mv to move submodules together with their work trees

 "git mv A B" when moving a submodule A does "the right thing",
 inclusing relocating its working tree and adjusting the paths in
 the .gitmodules file.

 Will cook in 'next'.
