Patch `transaction` to support abort hooks

Project Description

This package defines the parameterless function add_abort_hooks which patches transaction to support (before and after) abort hooks.

The support is analogous to that of before commit hooks. Especially, transaction._transaction.Transaction gets two new methods addBeforeAbortHook and addAfterAbortHook analoguous to addBeforeCommitHook with identical signature. The hooks are called at the begin or end, respectively, of Transaction.abort().

Note that the abort hooks are not called when the transaction is internally aborted during a transaction commit. In this case, the after commit hooks are called (with False as first parameter). Therefore, it is likely that you will register a corresponding pair of abort hook and after commit hook. In fact, I had expected that the after commit hooks would be called during abort as well, but the ZODB developers decided that not calling them on abort is a feature, not a bug.
