linux - Blocking threads in Python -

I have some Python code'm debug which is blocking problem I have some idea to me whether there but I do not know the python thread mechanism well to find out.

Here is the code:

  class executed: def Execute_many (commands): with_processes = Zip (command, Seldkprocess_cycle) (about Def) in order, process with_processes: send_command_to_process (process command) writing_thread = threading.Thread (target = writing) process _, with_processes to writing_thread.start (): yield receive_result_from_process (process) thread.join ()  

and elsewhere:

  results executor.execute_many (orders) for less important things = [make_foo (result)]  

< Code> process_cycle Executor Dawar subprocess.Popen objects. send_command_to_process and receive_result_from_process interact with these processes by pipes

The issue is debugging from time to time that this code is stored:. All popen processes and writing_thread are blocked at Flushing after writing to the pipe.

I did not expect it to happen, because (even though the buffers are full) execute_many generator will yield Receive_result_from_process (procedure) and processes One of the unblocked (which does not happen - inserting execute_many inside the loop).

So I came up with a hypothesis, that if writing_thread is blocked by a full pipe buffer, the main thread is also blocked (they are in the same process).

Is this possible? If so, a Python feature, or Linux feature?

TL; DR

If there is two threads in a Python process and one of them is blocked on flush after writing a full pipe buffer, can it block other threads?

If so, is it a Python feature, or Linux feature?

If a thread is blocked, then can continue execution to ensure other threads.
