filemerge: tag merge tool for blocked times
Merge tools can take a while - let's ensure that they're appropriately tagged
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 ..

>>> if regsize < gdsize:

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.
