Patch captureStackTrace/prepareStackTrace to ZoneAwareError, patch process.nextTick, fix removeAllListeners bug #516

JiaLiPassion · 2016-11-23T03:04:25Z

ZoneAwareError didn't add captureStackTrace method, so it will failed when user call Error.captureStackTrace. for example issue 0.7.1 Breaking Error #515
ZoneAwareError didn't add Error.prepareStackTrace callback, so if user add prepareStackTrace callback to Error, the callback will not be executed. for example issue 0.7.1 Breaking Error #515

https://github.com/v8/v8/wiki/Stack-Trace-API

patch process.nextTick with zone.scheduleMicroTask, so process.nextTick can be in zone, and can be handled by ZoneDelegate task related callback(onScheduleTask/onInvokeTask) Patch process.nextTick() #505
modify a typo, FrameType.trasition->FrameType.transition
fix EventEmitter.removeAllListeners bug Incompatabile with nodejs 6.9.1: makeZoneAwareRemoveAllListeners addes 'undefined' arguments to real removeAllListeners calls #518, when call EventEmitter.removeAllListeners without eventName, should remove all eventListener, and add some test cases for EventEmitter.removeListener/newListener.
update fetch to 2.0.1 in package.json

maybe use const better

yes, you are right, thank you.

… should remove all listeners

KrauseStefan

I've looked through the changes, keep in mind that I'm not directly attached to the project so take the feedback for what it is, I do however believe that a few changes are needed before a merge.

lib/common/utils.ts

+      // remove all listeners without eventName
+      target[EVENT_TASKS] = [];
+      target[symbol]();
+      return;


The real removeAllListeners(...)
return this
This wrapper should do the same
https://github.com/nodejs/node/blob/master/lib/events.js#L404

In typescript I believe you probably want to use either let or const as far as I can tell all except the logic in the loop can use const.

thanks, I will change the var to const.
and about the return this part, it has been handled by https://github.com/angular/zone.js/blob/master/lib/node/events.ts#L14

KrauseStefan · 2016-11-24T21:36:21Z

lib/common/utils.ts

    var eventName = args[0];
    var useCapturing = args[1] || defaultUseCapturing;
-    var target = self || _global;
    var eventTasks = findAllExistingRegisteredTasks(target, eventName, useCapturing, true);


When all all listeners are removed shouldn't all the eventTasks also be chanceled?
I believe we need to look into how to use findAllExistingRegisteredTasks to get and cancel all eventTasks.

the cancelTask will just call the original EventEmitter.removeListener, I think we don't need to cancel it, because when we call targetsymbol https://github.com/angular/zone.js/pull/516/files#diff-f5e084bcb7c43d977d56c3b791bbca2dR287, the EventEmitter.removeAllListeners will do it for us.

and the cancelTask call here is also not necessary either I think, https://github.com/angular/zone.js/blob/master/lib/common/utils.ts#L290

lib/node/node.ts

+    args[0] = function() {
+      task.invoke.apply(this, arguments);
+    };
+    setNative.apply(process, args);


Shouldn't this be setNative.apply(self, args) using the self variable coming from patchMethod? Not actually a problem since nextTick appears to bind callbacks to global, but still

yeah, we can pass the self form patchMethod to scheduleTask, but here we know it is process , so we can just use process directly, just like patch timer.https://github.com/angular/zone.js/blob/master/lib/common/timers.ts#L30

Do we know it's process?

var nextTick = process.nextTick; nextTick.call(myObject, function() { console.log(this); // If `nextTick` passed its context object directly to // its callback, this would be `myObject`. However, // with the zone.js patch, this would be `process` });

(I edited my code in the above comment, since it used to make no sense)

Yeah, but I can't imagine when we need to call like nextTick.call(myObject, ...), in my understanding we should always call nextTick.call(process, ...)

I also don't think there's ever a good reason to call nextTick with a different context, especially since with the current implementation (and probably all past/future implementations) it would be useless anyway. But it is allowable to use a different context, and so this could be a problem in the future. With setTimeout the DOM spec requires you to call it on an object of type Window or WorkerGlobalScope (i.e. the global scope)

Anyway, I'd prefer to see it the other way, but it honestly doesn't matter

I didn't know such kind of usage, thank you for the information. in this PR, I'll just keep it this way just to make the coding style be the same with patchTimer. Thanks again.

It seems weird to use this local variable instead of moving scheduleTask inside of patchMethod, but I guess you're trying to limit nested closures?

yeah, I agree, I just keep the coding style to be the same with timer patch, https://github.com/angular/zone.js/blob/master/lib/common/timers.ts#L17
