If I understand you correctly, LMDB would be safe to use in these scenarios in an ideal world:
- mdb_env_open(), fork(), exec() (without fd leaks I'd argue)
- mdb_env_open(), pthread_create(), fork()
- mdb_env_open(), fork()
As far as I understand you are after 2 and 3, while I want 1.
I'm after all three.
...if the user calls the cleanup function. But:
Whoops, correction: If you mean using LMDB after fork(), (2) can't be safe unless the user makes it safe with pthread_atfork(). But at least it can clean up some of the stuff (3) also does, and he'll have the pthread_atfork option if he really needs it.
