Non-blocking multiprocessing pipe
Installing
pip install pipe_nonblockSupported versions
- Python 3.4+
Usage
from pipe_nonblock import Pipe
c1, c2 = Pipe(duplex=True, conn1_nonblock=True, conn2_nonblock=True) # create a new duplex non-blocking pipe
assert len(list(c2.recv(32))) == 0 # try receive data from a connection, it's empty at the moment
c1.send('foo') # send python string object
buf, = c2.recv(32) # recv return generator with received objects
assert buf == 'foo'
c2.send('bar')
buf, = c1.recv(32)
assert buf == 'bar'Overview of Pipe function
def Pipe(duplex, conn1_nonblock, conn1_nonblock) -> Tuple[connection1, connection2]:| parameter | type | description |
|---|---|---|
| duplex | bool | If duplex is True (the default) then the pipe is bidirectional. If duplex is False then the pipe is unidirectional: conn1 can only be used for receiving messages and conn2 can only be used for sending messages. |
| conn1_nonblock | bool | If conn1_nonblock is True then the connection1 is non-blocking |
| conn2_nonblock | bool | If conn2_nonblock is True then the connection2 is non-blocking |
