[Libevent-users] bufferevent openssl deadlock
We've run into the same problem.
Our minimal fix (as opposed to the patch mentioned, which adds atomic operations to evthread) for our specific use case was this :
- expose event_base_lock() and event_base_unlock() to library users
- in the user code make sure to lock the event_base before writing to an openssl bufferevent, so no callbacks can be fired during that write (which results in a deadlock).
Does anybody have feedback on better ways to workaround this?
Hi Nick, would you mind sharing the changes you had in mind?
