Niels Thykier	179faeb23b	Update some comments to match a renamed method ... Signed-off-by: Niels Thykier <niels@thykier.net>	6 years ago
Niels Thykier	8cefd1a546	Have transactions verify/assert safe usage ... Have the transaction code verify that there is at most one active child at the time and no one is using the parent while child is active. This is how the code is intended to be used and also the code almost certainly does not work otherwise. The new code does not cover commiting/rolling back a parent before a child but that is already covered by the existing code (it will trigger when child transaction is rolled back/committed or when leaving the contextmanager from start_transaction). This would have caught 7d758760d1 immediately with an assertion error. Signed-off-by: Niels Thykier <niels@thykier.net>	6 years ago

Niels Thykier	c7dbd95c0b	Have MigrationManager keep track of active transaction ... This leaves callers with only having to track the transaction they need to care about (if any). Signed-off-by: Niels Thykier <niels@thykier.net>	6 years ago
Niels Thykier	a05a249e04	Record exactly which binaries are updated in the transaction ... Signed-off-by: Niels Thykier <niels@thykier.net>	6 years ago
Niels Thykier	5d49a41204	Introduce a "Transaction" for changes to testing ... This isolates the undo handling in the new transaction object and in doop_source, which currently generates the undo items. This commit will be a stepping stone to rewriting the undo handling.
