queue

问题 OVERVIEW I'm working on a project and I've come across a bit of a problem in that things aren't happening in the order I want them to happen. So I have been thinking about designing some kind of Queue that I can use to organize function calls and other miscellaneous JavaScript/jQuery instructions used during start-up, i.e., while the page is loading. What I'm looking for doesn't necessarily need to be a Queue data structure but some system that will ensure that things execute in the order I

问题 I am trying to download 100 files using a script I dont want at any point of time not more than 4 downloads are happening. So i have create a folder /home/user/file_limit . In the script it creates a file here before the download and after the download is complete it will delete it. The script will check the number of files in the folder is less than 4 then only it will allow to create a file in the folder /home/user/file_limit I am running a script like this today=`date +%Y-%m-%d-%H_%M_%S_%N

问题 I'm trying to transfer samples from thread A ("Acquisition") to thread B ("P300") using queue but I can't read any data in thread B, although samples are being allocated in thread A. Judging by my output, I think my thread B is rushing and testing things before my thread A starts to put data in. See an approximation of my code structure bellow: import threading import queue from queue import Empty import numpy as np import warnings warnings.filterwarnings("error") class AcqThread(threading

问题 The posted code starts two async Processes . The first publisher Process publishes data to the Queue , the second subscriber Process reads the data from the Queue and logs it to console. To make sure the Queue is not accessed at the same time, before getting the data from the Queue , the subscribe function first executes lock.acquire() , then gets the data with data = q.get() and finally releases the lock with the lock.release() statement. The same locking-releasing sequence is used in

问题 I'm currently implementing a sync queue service to sync a webapp's customers to Outlook's contacts. I'm using the Graph API for the job. The creation and updating of contacts is done using graph's batch request. There's a part in the docs about the response that I don't fully understand and pretty much ignored. I just want to make sure my implementation is correct. In addition to the responses property, there might be a nextLink property in the batch response. This allows Microsoft Graph to

问题 I facing a problem. I found a solution I'm explaining below but I want some advice aout to right way to resolve it. Here is the problem: I have a class object called Item . This Item has a method, call make_request which makes a GET request on a server, and save the result. Now, I have implemented 3 Item object which calls make_request . The Item objects gonna call the method each 3 minutes, but these make_requests must be delayed by 1 minutes from the previous object's call. Example : 14:00

问题 Say I want a queue where only 3 items are being processed asynchronously at any one time, how do I go about this? This is what I mean: If I have a collection of items to upload to the backend i.e. upload some artefacts to cloud storage and consequently create/update a doc to reflect the url of each artefact and I don't want to: Async/Await each upload operation before the next - as this would be slow Send everything off at the same time - this could lead to write hot-spotting or rate limiting
