What's cooking in git.git (Mar 2013, #02; Thu, 7)
--------------------------------------------------

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 tip of the 'master' is at 1.8.2-rc3.  Hopefully we can tag the
final sometime next week.

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"]

* mp/complete-paths (2013-03-05) 1 commit
  (merged to 'next' on 2013-03-05 at 929f7c5)
 + git-completion.zsh: define __gitcomp_file compatibility function

 A finishing touch for a new feature in the upcoming release.

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

* po/help-guides (2013-03-03) 5 commits
 - help doc: include --guide option description
 - help.c: add list_common_guides_help() function
 - help.c: add --guide option
 - help.c: use OPT_COUNTUP
 - show 'git help <guide>' usage, with examples

 Give more visibility to "concept guides" to help "git help" users.

 Expecting a reroll.

* jk/graph-c-expose-symbols-for-cgit (2013-03-03) 1 commit
  (merged to 'next' on 2013-03-04 at be35b12)
 + Revert "graph.c: mark private file-scope symbols as static"

 In the v1.8.0 era, we changed symbols that do not have to be global
 to file scope static, but a few functions in graph.c were used by
 CGit from sideways bypassing the entry points of the API the
 in-tree users use.

 Will cook in 'next'.


* we/submodule-update-prefix-output (2013-03-03) 1 commit
  (merged to 'next' on 2013-03-04 at 908df73)
 + submodule update: when using recursion, show full path

 Will cook in 'next'.


* jc/nobody-sets-src-peer-ref (2013-03-04) 1 commit
  (merged to 'next' on 2013-03-07 at 1910e21)
 + match_push_refs(): nobody sets src->peer_ref anymore

 Dead code removal.

 Will cook in 'next'.


* jc/push-follow-tag (2013-03-05) 4 commits
 - push: --follow-tags
 - commit.c: use clear_commit_marks_many() in in_merge_bases_many()
 - commit.c: add in_merge_bases_many()
 - commit.c: add clear_commit_marks_many()

 The new "--follow-tags" option tells "git push" to push relevant
 tags when pushing branches out.


* jc/maint-reflog-expire-clean-mark-typofix (2013-03-05) 1 commit
  (merged to 'next' on 2013-03-07 at 0a61cbb)
 + reflog: fix typo in "reflog expire" clean-up codepath

 Will cook in 'next'.


* aw/setup-prefix-pathspec (2013-03-07) 1 commit
 - setup.c: stop prefix_pathspec() from looping past the end of string

 Expecting a reroll.
 $gmane/217618


* gp/add-u-A-documentation (2013-03-07) 1 commit
 - add: Clarify documentation of -A and -u

 Looked good. We would need to start preparing a xx/add-u-A-2.0-default-to-top
 topic and update the messages this topic touches soon, though.

 Waiting for comments and then will merge to 'next'.


* lf/bundle-verify-list-prereqs (2013-03-07) 2 commits
 - bundle: Add colons to list headings in "verify"
 - bundle: Fix "verify" output if history is complete

 Will merge to 'next'.


* ks/rfc2047-one-char-at-a-time (2013-03-07) 1 commit
 - format-patch: RFC 2047 says multi-octet character may not be split

 When "format-patch" quoted a non-ascii strings on the header files,
 it incorrectly applied rfc2047 and chopped a single character in
 the middle of it.

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

* mb/gitweb-highlight-link-target (2012-12-20) 1 commit
 - Highlight the link target line in Gitweb using CSS

 Expecting a reroll.
 $gmane/211935


* jc/add-delete-default (2012-08-13) 1 commit
 - git add: notice removal of tracked paths by default

 "git add dir/" updated modified files and added new files, but does
 not notice removed files, which may be "Huh?" to some users.  They
 can of course use "git add -A dir/", but why should they?

 Resurrected from graveyard, as I thought it was a worthwhile thing
 to do in the longer term.

 There seems to be some interest. Let's see if it results in a solid
 execution of a sensible transition plan towards Git 2.0.


* mb/remote-default-nn-origin (2012-07-11) 6 commits
 - Teach get_default_remote to respect remote.default.
 - Test that plain "git fetch" uses remote.default when on a detached HEAD.
 - Teach clone to set remote.default.
 - Teach "git remote" about remote.default.
 - Teach remote.c about the remote.default configuration setting.
 - Rename remote.c's default_remote_name static variables.

 When the user does not specify what remote to interact with, we
 often attempt to use 'origin'.  This can now be customized via a
 configuration variable.

 Expecting a reroll.
 $gmane/210151

 "The first remote becomes the default" bit is better done as a
 separate step.

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

* kb/name-hash (2013-02-27) 1 commit
  (merged to 'next' on 2013-03-05 at 7f7e5d4)
 + name-hash.c: fix endless loop with core.ignorecase=true

 The code to keep track of what directory names are known to Git on
 platforms with case insensitive filesystems can get confused upon
 a hash collision between these pathnames and looped forever.

 Will cook in 'next'.


* rs/zip-compresssed-size-with-export-subst (2013-02-27) 1 commit
  (merged to 'next' on 2013-03-03 at c1ac6d8)
 + archive-zip: fix compressed size for stored export-subst files

 When export-subst is used, "zip" output recorded incorrect
 size of the file.

 Will cook in 'next'.


* hv/config-from-strbuf (2013-02-28) 4 commits
 - teach config parsing to read from strbuf
 - config: make parsing stack struct independent from actual data source
 - config: drop file pointer validity check in get_next_char()
 - config: factor out config file stack management

 Expecting a reroll.
 $gmane/217163


* jc/describe (2013-02-28) 1 commit
  (merged to 'next' on 2013-03-05 at 6b353f3)
 + describe: --match=<pattern> must limit the refs even when used with --all

 The "--match=<pattern>" option of "git describe", when used with
 "--all" to allow refs that are not annotated tags to be used as a
 base of description, did not restrict the output from the command
 to those that match the given pattern.

 We may want to have a looser matching that does not restrict to tags,
 but that can be done as a follow-up topic; this step is purely a bugfix.

 Will cook in 'next'.


* jk/mailsplit-maildir-muttsort (2013-03-02) 1 commit
  (merged to 'next' on 2013-03-03 at d5f7735)
 + mailsplit: sort maildir filenames more cleverly

 Will cook in 'next'.


* pc/subtree-add-before-fetch (2013-02-28) 1 commit
 - contrib/subtree: allow addition of remote branch with name not locally present

 Comments?


* tr/line-log (2013-02-28) 5 commits
 - log -L: :pattern:file syntax to find by funcname
 - Implement line-history search (git log -L)
 - Export rewrite_parents() for 'log -L'
 - blame: introduce $ as "end of file" in -L syntax
 - Refactor parse_loc


* jc/perl-cat-blob (2013-02-22) 1 commit
  (merged to 'next' on 2013-02-25 at 7c0079a)
 + Git.pm: fix cat_blob crashes on large files

 perl/Git.pm::cat_blob slurped everything in core only to write it
 out to a file descriptor, which was not a very smart thing to do.

 Will cook in 'next'.


* nd/doc-index-format (2013-02-23) 3 commits
  (merged to 'next' on 2013-02-26 at 4d3caea)
 + update-index: list supported idx versions and their features
 + read-cache.c: use INDEX_FORMAT_{LB,UB} in verify_hdr()
 + index-format.txt: mention of v4 is missing in some places

 Update the index format documentation to mention the v4 format.

 Will cook in 'next'.


* ap/maint-diff-rename-avoid-overlap (2013-03-06) 3 commits
  (merged to 'next' on 2013-03-06 at 3bc8dda)
 + tests: make sure rename pretty print works
  (merged to 'next' on 2013-02-26 at 19d70bf)
 + diff: prevent pprint_rename from underrunning input
  (merged to 'next' on 2013-02-25 at c9bd6d3)
 + diff: Fix rename pretty-print when suffix and prefix overlap

 The logic used by "git diff -M --stat" to shorten the names of
 files before and after a rename did not work correctly when the
 common prefix and suffix between the two filenames overlapped.

 Will cook in 'next'.


* ap/maint-update-index-h-is-for-help (2013-02-23) 1 commit
  (merged to 'next' on 2013-02-25 at f5f767c)

* nd/branch-error-cases (2013-02-23) 1 commit
  (merged to 'next' on 2013-02-25 at 1d0289f)
 + branch: segfault fixes and validation

 "git branch" had more cases where it did not bother to check
 nonsense command line parameters.

 Will cook in 'next'.


* rt/commit-cleanup-config (2013-02-23) 1 commit
  (merged to 'next' on 2013-02-25 at 8249b61)
 + t7502: perform commits using alternate editor in a subshell

 Fix tests that contaminated their environments and affected new
 tests introduced later in the sequence by containing their effects
 in their own subshells.

 Will cook in 'next'.


* wk/doc-pre-rebase (2013-02-24) 1 commit
  (merged to 'next' on 2013-02-25 at a6ec310)

* gp/describe-match-uses-glob-pattern (2013-02-24) 1 commit
  (merged to 'next' on 2013-02-26 at c9cc789)
 + describe: Document --match pattern format
 (this branch is used by gp/forbid-describe-all-match.)

 Will cook in 'next'.


* gp/forbid-describe-all-match (2013-02-24) 1 commit
 - describe: make --all and --match=PATTERN mutually incompatible
 (this branch uses gp/describe-match-uses-glob-pattern.)

 "describe --match=<pattern> --all <commit>" ought to mean "use refs
 that match <pattern> to describe <commit>; you do not have to limit
 yourself to annotated tags."  But it doesn't.  Disable the
 combination.

 We may want to discard this if jc/describe topic turns out to be a
 better idea.


* jk/common-make-variables-export-safety (2013-02-25) 1 commit
  (merged to 'next' on 2013-03-05 at 084ae43)
 + Makefile: make mandir, htmldir and infodir absolute

 Make the three variables safer to be exported to submakes by
 ensuring that they are full paths so that they can be used as
 installation location.

 Will cook in 'next'.


* jk/suppress-clang-warning (2013-02-25) 1 commit
 - fix clang -Wtautological-compare with unsigned enum


* mg/qnx6 (2013-02-25) 1 commit
 - QNX: newer QNX 6.x.x is not so crippled

 Still under discussion.
 Not ready for inclusion.

 - Fix time offset calculation in case of unsigned time_t
 - date.c: fix unsigned time_t comparison

 A few workarounds for systems with unsigned time_t.

 + fetch-pack: fix out-of-bounds buffer offset in get_ack
 + upload-pack: remove packet debugging harness
 + upload-pack: do not add duplicate objects to shallow list

 them more robust.

* ob/imap-send-ssl-verify (2013-02-20) 1 commit
  (merged to 'next' on 2013-02-25 at e897609)
 + imap-send: support Server Name Indication (RFC4366)

 Correctly connect to SSL/TLS sites that serve multiple hostnames on
 a single IP by including Server Name Indication in the client-hello.

 Will cook in 'next'.


* jc/format-patch (2013-02-21) 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.


* tk/doc-filter-branch (2013-02-26) 2 commits
  (merged to 'next' on 2013-02-26 at bd4638b)
 + Documentation: filter-branch env-filter example

  (merged to 'next' on 2013-02-19 at cf622b7)
 + Documentation/git-commit.txt: rework the --cleanup section
 + git-commit: only append a newline to -m mesg if necessary
 + t7502: demonstrate breakage with a commit message with trailing newlines
 + t/t7502: compare entire commit message with what was expected

 'git commit -m "$str"' when $str was already terminated with a LF
 now avoids adding an extra LF to the message.

 Will cook in 'next'.


* da/difftool-fixes (2013-02-21) 4 commits
  (merged to 'next' on 2013-02-25 at 687db1f)
 + t7800: "defaults" is no longer a builtin tool name

 + t7800: update copyright notice
 + difftool: silence uninitialized variable warning

 Minor maintenance updates to difftool, and updates to its tests.

* nd/read-directory-recursive-optim (2013-02-17) 1 commit
  (merged to 'next' on 2013-02-17 at 36ba9f4)
 + read_directory: avoid invoking exclude machinery on tracked files

 "git status" has been optimized by taking advantage of the fact
 that paths that are already known to the index do not have to be
 checked against the .gitignore mechanism under some conditions.

 Will cook in 'next'.


* mg/gpg-interface-using-status (2013-02-14) 5 commits
  (merged to 'next' on 2013-02-26 at 93f0e72)
 + pretty: make %GK output the signing key for signed commits
 + pretty: parse the gpg status lines rather than the output
 + gpg_interface: allow to request status return
 + log-tree: rely upon the check in the gpg_interface
 + gpg-interface: check good signature in a reliable way

 Call "gpg" using the right API when validating the signature on
 tags.

 Will cook in 'next'.


* jn/shell-disable-interactive (2013-02-11) 2 commits
 - shell: pay attention to exit status from 'help' command

* jc/fetch-raw-sha1 (2013-02-07) 4 commits
  (merged to 'next' on 2013-02-14 at ffa3c65)
 + fetch: fetch objects by their exact SHA-1 object names
 + upload-pack: optionally allow fetching from the tips of hidden refs
 + fetch: use struct ref to represent refs to be fetched
 + parse_fetch_refspec(): clarify the codeflow a bit

 Allows requests to fetch objects at any tip of refs (including
 hidden ones).  It seems that there may be use cases even outside
 Gerrit (e.g. $gmane/215701).

* mn/send-email-works-with-credential (2013-02-27) 6 commits
  (merged to 'next' on 2013-02-27 at ee7ae0e)

* nd/branch-show-rebase-bisect-state (2013-03-06) 4 commits
 - branch: show more information when HEAD is detached
 - status: show more info than "currently not on any branch"
 - wt-status: move wt_status_get_state() out to wt_status_print()
 - wt-status: split wt_status_state parsing function out

 This is hopefully almost there.


* nd/count-garbage (2013-02-15) 4 commits
  (merged to 'next' on 2013-02-17 at b2af923)
 + count-objects: report how much disk space taken by garbage files
 + count-objects: report garbage files in pack directory too
 + sha1_file: reorder code in prepare_packed_git_one()

  (merged to 'next' on 2013-02-27 at 7a261cb)
 + Add contrib/credentials/netrc with GPG support

 A new read-only credential helper (in contrib/) to interact with
 the .netrc/.authinfo files.  Hopefully mn/send-email-authinfo topic
 can rebuild on top of something like this.

 Will cook in 'next'.


* jl/submodule-deinit (2013-03-04) 1 commit
  (merged to 'next' on 2013-03-05 at 097164e)
 + submodule: add 'deinit' command

 There was no Porcelain way to say "I no longer am interested in
 this submodule", once you express your interest in a submodule with
 "submodule init".  "submodule deinit" is the way to do so.

 Will cook in 'next'.


* jc/remove-export-from-config-mak-in (2013-03-05) 3 commits
  (merged to 'next' on 2013-03-05 at abaa3cb)
 + Fix `make install` when configured with autoconf
  (merged to 'next' on 2013-02-12 at eb8af04)
 + Makefile: do not export mandir/htmldir/infodir
  (merged to 'next' on 2013-02-07 at 33f7d4f)
 + config.mak.in: remove unused definitions

 config.mak.in template had an "export" line to cause a few
 common makefile variables to be exported; if they need to be
 expoted for autoconf/configure users, they should also be exported
 for people who write config.mak the same way.  Move the "export" to
 the main Makefile.  Also, stop exporting mandir that used to be
 exported (only) when config.mak.autogen was used.  It would have
 broken installation of manpages (but not other documentation
 formats).

* jc/remove-treesame-parent-in-simplify-merges (2013-01-17) 1 commit
  (merged to 'next' on 2013-01-30 at b639b47)
 + simplify-merges: drop merge from irrelevant side branch

 The --simplify-merges logic did not cull irrelevant parents from a
 merge that is otherwise not interesting with respect to the paths
 we are following.

 This touches a fairly core part of the revision traversal
 infrastructure; even though I think this change is correct, please
 report immediately if you find any unintended side effect.
