问题 Some backstory: My server ran out of disk space last night while delayed_job workers were running off jobs processing images. When I try to stop the workers, I get the response "Terminated". RAILS_ENV=production script/delayed_job stop Terminated Then I run the following to see that the workers were terminated. ps -ef | grep delayed_job servername 4474 4274 0 02:37 pts/1 00:00:00 grep --color=auto delayed_job Now I try to start up new workers. RAILS_ENV=production script/delayed_job -n2 start

问题 I'm not totally understanding the difference between the close() vs terminate() methods for Web Workers. I've read the descriptions here and it seems to be doing the same thing?? http://www.w3.org/TR/workers/ When would I use one over the other? 回答1: The close() method is visible inside the worker's scope. The terminate() method is a part of the worker object's interface and can be called "from the outside". If you create a worker in your main script and want to stop it from that script you

问题 Can VS Code's Javascript debugger be made to debug node 11's new "Worker Threads"? Worker threads are modelled after web workers with a small number of extra capabilities on top and are available from the new worker_threads package (see https://nodejs.org/api/worker_threads.html). Other than with node's sub processes, one can share memory with worker threads in the form of SharedArrayBuffers. My VS Code launch configuration looks like that: { "type": "node", "request": "launch", "name":

问题 I am writing an npm package which is a plugin for the popular library leafletjs. I am using webpack to bundle the package. I want this package to be able to spawn and destroy some web workers on command. The web worker code is part of my source files. But I want to be able to distribute my package both as an npm module, or through a cdn, meaning it must be compiled down to a singular file that can be included through an HTML header. I am using webpack to do it. So lets say I have a worker

问题 I'm getting the following error Uncaught TypeError: Failed to execute 'postMessage' on 'DedicatedWorkerGlobalScope': The provided value cannot be converted to a sequence. on this line in a webworker: postMessage("hi", "http://localhost:8000"); (in fact, that is the entirety of the webworker). The base file contains: var myWorker = new Worker("test.js"); myWorker.onmessage = function (e) { console.log('Message received from worker'); }; I'm not sure which value it's complaining about and I'm

问题 I'm getting the error WARN [web-server]: 404: /app/workers/total.js when trying to run a unit test on a web worker. Karma.conf.js includes the following: ... files: [ ...
