What's cooking in git.git (Dec 2010, #05; Thu, 16)

[Junio C Hamano <gitster@pobox.com>]

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.

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

* jn/maint-gitweb-pathinfo-fix (2010-12-14) 1 commit
  (merged to 'next' on 2010-12-14 at 1af8cca)
 + gitweb: Fix handling of whitespace in generated links

* rj/maint-difftool-cygwin-workaround (2010-12-14) 1 commit
 - difftool: Fix failure on Cygwin

* rj/maint-test-fixes (2010-12-14) 5 commits
 - t9501-*.sh: Fix a test failure on Cygwin
 - lib-git-svn.sh: Add check for mis-configured web server variables
 - lib-git-svn.sh: Avoid setting web server variables unnecessarily

 - t3600-rm.sh: Don't pass a non-existent prereq to test #15

* rj/test-fixes (2010-12-14) 4 commits
 - t4135-*.sh: Skip the "backslash" tests on cygwin
 - t3032-*.sh: Do not strip CR from line-endings while grepping on MinGW
 - t3032-*.sh: Pass the -b (--binary) option to sed on cygwin
 - t6038-*.sh: Pass the -b (--binary) option to sed on cygwin

* tr/maint-branch-no-track-head (2010-12-14) 1 commit
 - branch: do not attempt to track HEAD implicitly

Probably needs a re-roll to exclude either (1) any ref outside the
hierarchies for branches (i.e. refs/{heads,remotes}/), or (2) only refs
outside refs/ hierarchies (e.g. HEAD, ORIG_HEAD, ...).  The latter feels
safer and saner.

* by/log-l (2010-12-14) 8 commits
 . log -L: implement move/copy detection (-M/-C)
 . log -L: add --full-line-diff option
 . log -L: add --graph prefix before output
 . log -L: support parent rewriting
 . Implement line-history search (git log -L)
 . Export rewrite_parents() for 'log -L'
 . Export three functions from diff.c
 . Refactor parse_loc

Seems to have some bad interactions with nd/struct-pathspec.

* hv/mingw-fs-funnies (2010-12-14) 5 commits
 - mingw_rmdir: set errno=ENOTEMPTY when appropriate
 - mingw: add fallback for rmdir in case directory is in use
 - mingw: make failures to unlink or move raise a question

 - mingw: move unlink wrapper to mingw.c

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

* nd/index-doc (2010-09-06) 1 commit
 - doc: technical details about the index file format

Half-written but it is a good start.  I may need to give some help in
describing more recent index extensions.

* cb/ignored-paths-are-precious (2010-08-21) 1 commit
 - checkout/merge: optionally fail operation when ignored files need to be overwritten

This needs tests; also we know of longstanding bugs in related area that
needs to be addressed---they do not have to be part of this series but
their reproduction recipe would belong to the test script for this topic.

It would hurt users to make the new feature on by default, especially the
ones with subdirectories that come and go.

* jk/tag-contains (2010-07-05) 4 commits
 - Why is "git tag --contains" so slow?
 - default core.clockskew variable to one day
 - limit "contains" traversals based on commit timestamp
 - tag: speed up --contains calculation

The idea of the bottom one is probably Ok, except that the use of object
flags needs to be rethought, or at least the helper needs to be moved to
builtin/tag.c to make it clear that it should not be used outside the
current usage context.

* tr/config-doc (2010-10-24) 2 commits
 . Documentation: complete config list from other manpages
 . Documentation: Move variables from config.txt to separate file

This unfortunately heavily conflicts with patches in flight...

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

* nd/oneline-sha1-name-from-specific-ref (2010-12-13) 3 commits
 - get_sha1: support $commit^{/regex} syntax
 - get_sha1_oneline: make callers prepare the commit list to traverse
 - get_sha1_oneline: fix lifespan rule of temp_commit_buffer variable

This should be more or less ready for 'next'.

* mg/cvsimport (2010-11-28) 3 commits
 - cvsimport.txt: document the mapping between config and options
 - cvsimport: fix the parsing of uppercase config options
 - cvsimport: partial whitespace cleanup

I was being lazy and said "Ok" to "cvsimport.capital-r" but luckily other
people injected sanity to the discussion.  Weatherbaloon patch sent, but
not queued here.

* tf/commit-list-prefix (2010-11-26) 1 commit
 - commit: Add commit_list prefix in two function names.

This churn already introduced an unnecessary conflict.  It is not by
itself a biggie, but these things tend to add up.

* pd/bash-4-completion (2010-12-15) 3 commits
 - Merge branch 'master' (early part) into pd/bash-4-completion
 - bash: simple reimplementation of _get_comp_words_by_ref
 - bash: get --pretty=m<tab> completion to work with bash v4

Updated by Jonathan; this still has some conflicts around "notes"
completion I tried to resolve near the tip of 'pu'.

* jn/svn-fe (2010-12-06) 18 commits
 - vcs-svn: Allow change nodes for root of tree (/)
 - vcs-svn: Implement Prop-delta handling

 - vcs-svn: Reject path nodes without Node-action
 - vcs-svn: Delay read of per-path properties

 - vcs-svn: handle_node: Handle deletion case early
 - vcs-svn: Use mark to indicate nodes with included text
 - vcs-svn: Unclutter handle_node by introducing have_props var
 - vcs-svn: Eliminate node_ctx.mark global
 - vcs-svn: Eliminate node_ctx.srcRev global
 - vcs-svn: Check for errors from open()
 - vcs-svn: Allow simple v3 dumps (no deltas yet)
 - vcs-svn: Error out for v3 dumps

Some RFC patches, to give them early and wider exposure.

 - unpack-trees: move all skip-worktree checks back to unpack_trees()
 - dir.c: add free_excludes()

 . gitweb: Add more explicit means of disabling 'Generating...' page
 . gitweb: Regression fix concerning binary output of files
 . gitweb: Minimal testing of gitweb caching
 . gitweb: File based caching layer (from git.kernel.org)
 . gitweb: add output buffering and associated functions
 . gitweb: Prepare for splitting gitweb

It appears that John and Jakub are finally working together to help
producing something that we can ship in-tree, finally.  I am looking
forward to seeing the conclusion of the discussion.

It is getting ridiculously painful to keep re-resolving the conflicts with
other topics in flight, even with the help with rerere.

Needs a bit more minor work to get the basic code structure right.
