gevent-compatible reentrant lock?

Question

What is the RLock equivalent in gevent? If there is no equivalent, how to identify the current greenlet so I can implement one?

From reading the source, gevent.lock.BoundedSemaphore(1) is the equivalent of a simple (non-reentrant) Lock. Testing also indicates this.

Answer 1

The gevent.lock module has an implementation of RLock which uses the getcurrent method of gevent.hub to identify the current greenlet. Here is a simple example.

from gevent.lock import RLock

lock = RLock()
with lock:
     print("acquired once")
     with lock:
          print("acquired twice")

While I didn't find any documentation here, you can always read the source.
