Is putting an object in a multi-processing queue independent from getting an object from it? In other words, will putting an object block the process P1 if another process P2 is getting from it? Update: I am assuming an infinite queue. My reading of the source code is that get obtains a read lock, which is independent of of the lock (called _notempty ) acquired by put . If I understand correctly, concurrent get s can block each other, and concurrent put s can block each other (modulo your use of the block parameter), but that gets and puts do not mutually block. 来源： https://stackoverflow.com

I am working on a practical scenario related with Java;a socket program. The existing system and the expected system are as follows. Existing System - The system checks that a certain condition is satisfied. If so It will create some message to be sent and put it into a queue. The queue processor is a separate thread. It periodically check the queue for existence of items in it. If found any items (messages) it just sends the message to a remote host (hardcoded) and remove the item from queue. Expected System - This is something like that. The message is created when a certain condition is

I have data in my application which must be updated on the server on the basis of network availability. I store this data on a local database on android using sqlite. Currently the idea is: Data should be inserted on the local sqlite database A service should be waiting as soon as the data is inserted it checks the network availability and send it to the server and wait for success response. If the response true is received from the server it should update the sync status of that sqlite row and move to the next row to send the data. I wanted to find out the best way to queue this data to send

Closed . This question is opinion-based . It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post . Closed 3 years ago . I needed to know if laravel 5 queue management system is suitable for big projects (having about 100.000 users). I want to do something like messaging (not spam :) ) users at once each day. Is redis good enough for this job (queuing)? Or it is better to use a lib that is specially for queuing (like beanstalkd)? To be fair and to try and post a reasonable answer to this

I have trouble understanding why this simple program raises an EOFError at the end. I am using a Queue() to communicate with a Thread() that I want to automatically and cleanly terminate atexit of my program. import threading import multiprocessing import atexit class MyClass: def __init__(self): self.queue = None self.thread = None def start(self): self.queue = multiprocessing.Queue() self.thread = threading.Thread(target=self.queued_writer, daemon=True) self.thread.start() # Remove this: no error self.queue.put("message") def queued_writer(self): while 1: msg = self.queue.get() print(
