Re: LMDB transaction flags

Hello, I'd like to be able to know if a LMDB transaction is active, valid, dirty, read-only, etc.

Why? There is no valid reason for these details to be exposed to LMDB callers. All LMDB users need to know is whether they have created a valid txn, and whether they want to abort it or commit it.

From the documentation I read that such information is in mt_flags of the mdb_txn structure, which is opaque. I don't see any function exposing mt_flags. Is there any other way to read that information?

No. Nor are the flag definitions public.
