Subject: Expose txn_begin/commit/rollback
Download (untitled) / with headers

While txn_do() is definitely a best practice, it is sometimes easier to use txn_begin/commit/rollback. These are provided by back-ends implementing the TXN role, but is not provided by KiokuDB or KiokuDB::Role::API to us, the little people. Cheers, Sterling

FWIW, I see $dir->backend as perfectly fair game for the end user, since it supports various extensions to the API. That said, I'll add these to the next release anyway.

Bah, now I remembered why I didn't expose these. txn_begin can return a txn handle which txn_commit/rollback can expect to get back as an argument. I think I'm going to roll back this change because the BDB backend relies on this and it's going to be hard to expect the users to comply actually comply with this. If you'd like to implement a stack in KiokuDB.pm to manage this, then be my guest, but please make it pretty anal about providing errors)
