shelve: fix dirstate corruption during unshelve (
issue4055)
If you shelved on top of commit A, then rebased A to @ and unshelved, any file
changed in A would appear as modified in hg status despite the contents not having
changed.
The fix is to use dirstate.setparents() instead of doing it manually. This will
be a little slower since it has to iterate through everything in the dirstate
instead of only what's in the mergestate, but this will be more correct since
the mergestate did not include files which were merged but had no conflict.
The tests also had several bad dirstate's hardcoded in them. This change updates
the tests appropriately and adds a new test to cover this specific rebase case.
changegroup: don't run changegroup hooks if nodes are gone
The changegroup hook runs when the repo lock is released, but it's possible that
multiple transactions have happened during that single lock and therefore the
commits the hook was for may be gone. This is the case in the shelve extension
where it adds a commit and strips it in the same lock but different
transactions (which results in warning messages during unshelve on hgsubversion
repos).
A real fix would be to attach the hook to the transaction instead, but that
might have unknown consequences. Since we're this close to code-freeze, this fix
just prevents the hook from running if the commit disappeared.
shelve: make no_backup parameter passing python 2.4 compatible
Python 2.4 doesn't allow passing named parameter after an list unpack,
but allows to unpack a dict.
