python - ZeroMQ bidirectional async communication with subprocesses -


i have server process receives requests web clients. server has call external worker process ( .py ) streams data server , server streams client.

the server has monitor these worker processes , send messages them ( kill them or send messages control kind of data gets streamed ). these messages asynchronous ( e.g. depend on web client )

i thought in using zeromq sockets on ipc://-transport-class , call socket.recv() method blocking.

should use 2 sockets ( 1 streaming data server , receive control messages server )?

using separate socket signalling , messaging better

while poller-instance bit, cardinal step use separate socket signalling , 1 data-streaming. always. point is, in such setup, both poller.poll() , event-loop can remain socket-specific , spent not more predefined amount of time, during real-time controlled code-execution.

so, not hesitate setup bit richer signalling/messaging infrastructure environment enjoy increased simplicity of control, separation of concerns , clarity of intents.

zeromq excellent tool doing - including per-socket io-thread affinity, indeed fine-grain performance tuning available @ fingertips.

resizing Telegram inline keyboard -

telegram's inline keyboard great feature lots of different use cases. inline buttons added list of items this: inline_keyboard = [[inlinekeyboardbutton(text="button", callback_data="button"), inlinekeyboardbutton(text="reset",callback_data="reset")]] inline_keyboard_markup = inlinekeyboardmarkup(inline_keyboard) update.message.reply_text("hi", reply_markup=inline_keyboard_markup) the above code adds 2 buttons each half width of chat screen. i know the normal keyboard button there resize_keyboard parameter somehow can used. my question is there way resize inline buttons ? example make full width or quarter width. unfortunately, can't now. :( you can suggest @botsupport , might add feature next version.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
