bmstore: add handling of the active bookmark
This further centralizes the handling of bookmark storage, and will
help get some lingering bookmarks business out of localrepo. Right
now, this change implies reading of the active bookmark to also imply
reading all bookmarks from disk - for users with many many bookmarks
this may be a measurable performance hit. In that case, we should
migrate bmstore to be able to lazy-read its properties from disk
rather than having to eagerly read them, but I decided to avoid doing
that to try and avoid some potentially complicated filecache decorator
issues.
This doesn't move the logic for writing the active bookmark into a
transaction, though that is probably the correct next step. Since the
API probably needs to morph a little more, I didn't bother marking
bookmarks.{activate,deactivate} as deprecated yet.

Check whether size of generaldelta revlog is not bigger than its regular equivalent. Test would fail if generaldelta was naive implementation of parentdelta: third manifest revision would be fully inserted due to big distance from its paren revision (zero). $ hg init repo --config format.generaldelta=no --config format.usegeneraldelta=no $ cd repo $ echo foo > foo $ echo bar > bar $ echo baz > baz $ hg commit -q -Am boo $ hg clone --pull . ../gdrepo -q --config format.generaldelta=yes $ for r in 1 2 3; do > echo $r > foo > hg commit -q -m $r > hg up -q -r 0 > hg pull . -q -r $r -R ../gdrepo > done $ cd .. >>> import os >>> regsize = os.stat("repo/.hg/store/00manifest.i").st_size >>> gdsize = os.stat("gdrepo/.hg/store/00manifest.i").st_size >>> if regsize < gdsize: ... print 'generaldata increased size of manifest' Verify rev reordering doesnt create invalid bundles (issue4462) This requires a commit tree that when pulled will reorder manifest revs such that the second manifest to create a file rev will be ordered before the first manifest to create that file rev. We also need to do a partial pull to ensure reordering happens. At the end we verify the linkrev points at the earliest commit. $ hg init server --config format.generaldelta=True $ cd server $ touch a $ hg commit -Aqm a $ echo x > x $ echo y > y $ hg commit -Aqm xy $ hg up -q '.^' $ echo x > x $ echo z > z $ hg commit -Aqm xz $ hg up -q 1 $ echo b > b $ hg commit -Aqm b $ hg merge -q 2 $ hg commit -Aqm merge $ echo c > c $ hg commit -Aqm c $ hg log -G -T '{rev} {shortest(node)} {desc}' @ 5 ebb8 c | o 4 baf7 merge |\ | o 3 a129 b | | o | 2 958c xz | | | o 1 f00c xy |/ o 0 3903 a $ cd .. $ hg init client --config format.generaldelta=false --config format.usegeneraldelta=false $ cd client $ hg pull -q ../server -r 4 $ hg debugindex x rev offset length base linkrev nodeid p1 p2 0 0 3 0 1 1406e7411862 000000000000 000000000000 $ cd ..
