Subject: What's cooking in git.git (Aug 2011, #04; Tue, 16)
X-master-at: 4bfe7cb6668c43c1136304bbb17eea1b3ddf0237

What's cooking in git.git (Aug 2011, #04; Tue, 16)
--------------------------------------------------
Here are the topics that have been cooking. Commits prefixed with '-' are
only in 'pu' while commits prefixed with '+' are in 'next'.
The kernel.org machine seems to be very busy for the past 48 hours so it
might take a while for tonight's pushout to propagate to mirrors.
There are a few 'fixup!' commits queued in topics still in 'pu', so that
authors have a choice to just say "that fix looks good, squash it in!"
instead of going through an extra round.
--------------------------------------------------
[New Topics]
* di/fast-import-deltified-tree (2011-08-14) 2 commits
- fast-import: prevent producing bad delta
- fast-import: add a test for tree delta base corruption
* di/parse-options-split (2011-08-11) 2 commits
- Reduce parse-options.o dependencies
- parse-options: export opterr, optbug
* mh/attr (2011-08-14) 7 commits
- Unroll the loop over passes
- Change while loop into for loop
- Determine the start of the states outside of the pass loop
- Change parse_attr() to take a pointer to struct attr_state
- Increment num_attr in parse_attr_line(), not parse_attr()
- Document struct match_attr
- Add a file comment
All looked reasonable.
* mh/iterate-refs (2011-08-14) 6 commits
- Retain caches of submodule refs
- Store the submodule name in struct cached_refs
- Allocate cached_refs objects dynamically
- Change the signature of read_packed_refs()
- Access reference caches only through new function get_cached_refs()
- Extract a function clear_cached_refs()
* jn/plug-empty-tree-leak (2011-08-16) 2 commits
- merge-recursive: take advantage of hardcoded empty tree
- revert: plug memory leak in "cherry-pick root commit" codepath
Both looked reasonable.
--------------------------------------------------
[Stalled]
* jc/merge-reword (2011-05-25) 2 commits
- merge: mark the final "Merge made by..." message for l10n
- merge: reword the final message
Probably the topmost commit should be dropped.
* nk/branch-v-abbrev (2011-07-01) 1 commit
- branch -v: honor core.abbrev
Perhaps needs an updated commit log message?
* di/fast-import-doc (2011-07-13) 2 commits
- doc/fast-import: document feature import-marks-if-exists
- doc/fast-import: clarify notemodify command
Comments from fast-import folks?
* jh/receive-count-limit (2011-05-23) 10 commits
- receive-pack: Allow server to refuse pushes with too many objects
- pack-objects: Estimate pack size; abort early if pack size limit is exceeded
- send-pack/receive-pack: Allow server to refuse pushing too large packs
- pack-objects: Allow --max-pack-size to be used together with --stdout
- send-pack/receive-pack: Allow server to refuse pushes with too many commits
- pack-objects: Teach new option --max-commit-count, limiting #commits in pack
- receive-pack: Prepare for addition of the new 'limit-*' family of capabilities
- Tighten rules for matching server capabilities in server_supports()
- send-pack: Attempt to retrieve remote status even if pack-objects fails
- Update technical docs to reflect side-band-64k capability in receive-pack
Would need another round to separate per-pack and per-session limits.
* jm/mergetool-pathspec (2011-06-22) 2 commits
- mergetool: Don't assume paths are unmerged
- mergetool: Add tests for filename with whitespace
I think this is a good idea, but it probably needs a re-roll.
Cf. $gmane/176254, 176255, 166256
* jk/generation-numbers (2011-07-14) 7 commits
- limit "contains" traversals based on commit generation
- check commit generation cache validity against grafts
- pretty: support %G to show the generation number of a commit
- commit: add commit_generation function
- add metadata-cache infrastructure
- decorate: allow storing values instead of pointers
- Merge branch 'jk/tag-contains-ab' (early part) into HEAD
The initial "tag --contains" de-pessimization without need for generation
numbers is already in; backburnered.
* sr/transport-helper-fix-rfc (2011-07-19) 2 commits
- t5800: point out that deleting branches does not work
- t5800: document inability to push new branch with old content
* po/cygwin-backslash (2011-08-05) 2 commits
- On Cygwin support both UNIX and DOS style path-names
- git-compat-util: add generic find_last_dir_sep that respects is_dir_sep
I think a further refactoring (no, not my suggestion) was offered?
--------------------------------------------------
[Cooking]
