The checkexact() helper function was calling repo.rollback() from inside an open transaction. In addition to being insane, this is unnecessary because import will release the transaction on an exception. It turns out that this has been broken since the feature was first introduced, first released in v1.0: changeset: 4263:3e8ce73e04cd user: Brendan Cully <brendan@kublai.com> date: Thu Mar 22 10:44:59 2007 -0700 files: mercurial/commands.py mercurial/patch.py description: Add import --exact. When this option is set, import will apply the patch (which must be generated by export) to the parents specified in the patch, and check that the node produced by the patch matches the node ID in the patch.
