convert: add a config option to help doing identity hg->hg conversion
I want to change the computation of the list of files modified by a
commit. In principle, this would simply change a cache. But since this
information is stored in commits rather than a cache, changing it
means changing commit hashes (going forward).
Some users rely on the convert extension from hg to hg not changing
hashes when nothing changes (usually). Allow these users to preserve
hashes despite changes to the changelog files computation by reusing
these files lists when the manifest is unchanged (since these files
list are derived from the manifest).

#require no-reposimplestore 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). $ cat << EOF >> $HGRCPATH > [format] > sparse-revlog = no > EOF $ 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 .. >>> from __future__ import print_function >>> 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 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 ..
