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 ..
