worker

问题 I'm writing a Jest test and am having trouble resolving this import which uses webpack's worker-loader import ImageInfoWorker from 'worker-loader?name=image_info!@WORKERS/image-info'; I have some other aliases which are resolving properly in my tests, such as: import Store from '@SUPPORT/store'; import * as api from '@SUPPORT/api'; Here is the relevant snippet from package.json "jest": { "moduleFileExtensions": ["js", "jsx"], "moduleNameMapper": { "^@CSS/(.*)$": "<rootDir>/css/$1", "^

问题 I like the simplicity of invokeLater() for sending units of work to the AWT EDT. It would be nice to have a similar mechanism for sending work requests to a background thread (such as SwingWorker) but as I understand it, these do not have any sort of event queueing & dispatch mechanism, which is what invokeLater() depends upon. So instead, I've ended up giving my background thread a blocking queue, to which other threads send messages, and the thread essentially runs a receive loop, blocking

问题 I am using Laravel 5.6 and I am dispatching jobs to a queue and then using supervisor to activate 8 workers on that queue. I was expecting that Laravel will know NOT to run the same job twice but I was surprised to discover that it did. Same job was taken cared of by more than one worker and therefore weird stuff started to happen. The thing is that one year ago I wrote the same mechanism for another Laravel project (but on Laravel version 5.1) and the whole thing worked out of the box. I

问题 I need to invoke this: string input_ip_r = listView1.Items[lc].SubItems[1].Text; so I used if (InvokeRequired) { this.Invoke(new MethodInvoker(function)); return; } This worked but now I have put it into a BackgroundWorker and using this if (InvokeRequired) { this.Invoke(new MethodInvoker(bw.RunWorkerAsync)); return; } it gives an error that you can only run BackgroundWorker one at a time. So how do I invoke while in the Backgroundworker ? 回答1: I'm not quite sure how you want to use the

问题 I am trying to serve long running requests using gunicorn and its async workers but I can't find any examples that I can get to work. I used the example here but tweaked to add a fake delay (sleep for 5s) before returning the response: def app(environ, start_response): data = "Hello, World!\n" start_response("200 OK", [ ("Content-Type", "text/plain"), ("Content-Length", str(len(data))) ]) time.sleep(5) return iter([data]) Then I run gunicorn so: gunicorn -w 4 myapp:app -k gevent When I open

问题 I have a worker role in my hosted service. The worker is sending e-mail daily bases. But in the hosted service, there are 2 environment, Staging and Production. So my worker role sends e-mail 2 times everyday. I'd like to know how to detect if the worker is in stagning or production. Thanks in advance. 回答1: As per my question here, you'll see that there is no fast way of doing this. Also, unless you really know what you are doing, I strongly suggest you not do this . However, if you want to,

问题 I'm having trouble calling methods from an included module inside a resque worker. In the example below, I keep getting undefined method errrors when I attempt to call the say method inside the worker (which is in the TestLib module). I've reduced the code down to bare basics to illustrate the issue: Controller (/app/controllers/test_controller.rb) class TestController < ApplicationController def testque Resque.enqueue( TestWorker, "HI" ) end end Library (/lib/test_lib.rb) module TestLib def

问题 I'm trying to couple the execution of a spawned process in a worker pool to a new system terminal. In the following example (adapted from @sylvain-leroux's answer to this question) a pool of workers is constructed to do some work with queued objects. import os import time import multiprocessing # A main function, to be run by our workers. def worker_main(queue): print('The worker at', os.getpid(), 'is initialized.') while True: # Block until something is in the queue. item = queue.get(True)

问题 I'm working on a JavaFX application that let's the user select a folder and then parse it's contents to find MP3 files and read their metadata. I got this working with Swing although I found it hard to make the user interface look good. Thus I'm trying to do the same in JavaFX. In the original Swing app, I create a thread which starts the parsing of files in the folder the user selected. It works like this: Find out total number of files to parse - The number of files and the number of
