What's cooking in git.git (Dec 2011, #07; Mon, 19)

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 second large batch of topics for 1.7.9 graduated to 'master', and the tip of it should be 85% feature complete for this cycle (modulo fixes and tweaks).

Here are the repositories that have my integration branches:

With maint, master, next, pu, todo:

        git://git.kernel.org/pub/scm/git/git.git
        git://repo.or.cz/alt-git.git
        https://code.google.com/p/git-core/
        https://github.com/git/git

With only maint and master:

        git://git.sourceforge.jp/gitroot/git-core/git.git
        git://git-core.git.sourceforge.net/gitroot/git-core/git-core

With all the topics and integration branches:

        https://github.com/gitster/git

The preformatted documentation in HTML and man format are found in:

The lf-to-crlf filter in the streaming checkout codepath forgot that we try not to convert LF to CRLF if the repository data already has CRLF.

Probably solving a wrong problem and encouraging a wrong workflow while at it. jc/advise-push-default might be a better approach.

 - new representation types in the packstream
 - varint-in-pack: refactor varint encoding/decoding

Not ready.

At least pack-objects and fsck need to learn the new encoding for the series to be usable locally, and then index-pack/unpack-objects needs to learn it to be used remotely.

 - gpg-interface: allow use of a custom GPG binary
 - pretty: %G[?GS] placeholders
 - test "commit -S" and "log --show-signature"

Not urgent.
