absorb: preserve branch-closing changesets even if empty
This makes the behavior consistent with 'hg commit', which allows to create
otherwise empty changesets if they close the branch. A lost branch closure can
inadvertently re-open a branch, so it should be preserved.

#require no-reposimplestore Check whether size of generaldelta revlog is not bigger than its regular equivalent.

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 debugdeltachain x rev chain# chainlen prev delta size rawsize chainsize ratio lindist extradist extraratio 0 1 1 -1 base 3 2 3 1.50000 3 0 0.00000 $ cd ..
