No sidedata is generated in the source

  $ hg debugsidedata -c 0

Check that sidedata capabilities are advertised

  $ hg debugcapabilities ../target-repo | grep sidedata

We expect the client to abort the push since it's not capable of generating

what the server is asking

  $ hg push -r . ../target-repo

  pushing to ../target-repo

  abort: cannot push: required sidedata category not supported by this client: '1'

(Push) Difference is not subset/superset

----------------------------------------

Source has one in common, one missing and one more sidedata category with the

target.

  $ rm -rf source-repo target-repo

  $ hg init source-repo --config experimental.revlogv2=enable-unstable-format-and-corrupt-my-data

  $ hg debugcapabilities . | grep sidedata

  $ hg debugcapabilities ../target-repo | grep sidedata

Sidedata is generated in the source, but only the right categories (entry-0001 and entry-0002)

  $ hg debugsidedata -c 0

  2 sidedata entries

   entry-0001 size 4

   entry-0002 size 32

  $ hg debugsidedata -c 1 -v

  2 sidedata entries

   entry-0002 size 32

  $ hg debugsidedata a 1

  2 sidedata entries

   entry-0001 size 4

   entry-0002 size 32

We expect the target to have sidedata that was generated by the source on push,

and also removed the sidedata categories that are not supported by the target.

Namely, we expect entry-0002 (only exchanged) and entry-0003 (generated),

but not entry-0001.
