@Trott what happens if you use setImmediate()?

Trott · 2016-06-05T04:47:12Z

CI with change to setImmediate() instead of full timer elimination: https://ci.nodejs.org/job/node-test-pull-request/2924/

Trott · 2016-06-05T05:24:55Z

setImmediate() seems to be just fine on Windows. 🎉

Trott · 2016-06-05T05:26:05Z

Re-running CI again because all the ARM stuff blew up, wow: https://ci.nodejs.org/job/node-test-pull-request/2925/

cjihrig · 2016-06-05T13:32:23Z

LGTM. The CI blew up again though.

Fishrock123 · 2016-06-05T13:52:08Z

lib/_debugger.js

-      self.resume();
-    });
-  }, 10);
+  setImmediate(() => { self.run(function() { self.resume(); }); });


self.run(self.resume)?

Also can you drop self for this now?

Also can you drop self for this now?

Oh, right, arrow functions, lexical binding...

self.run(self.resume)?

test/parallel/test-debugger-util-regression.js fails if self.resume/this.resume is not wrapped in a function. (I did not look to see why...)

Probably because of this not being set properly.

lib/_debugger.js

-      self.resume();
-    });
-  }, 10);
+  setImmediate(() => { this.run(() => { this.resume; }); });


You're no longer calling resume()?

Heh, looks like we don't have a test that covers that. Guess I'll be adding one.

It seems that .resume() might be unnecessary:

.run() calls either .error() or trySpawn()

.error() will call .resume()

trySpawn() will call .resume() in a ready event listener on client

Trott · 2016-06-06T22:37:03Z

rebased, removed .resume() that was accidentally discovered to be unnecessary, force pushed...

@indutny @cjihrig Can you confirm that this still looks good to you (assuming CI doesn't have any surprises)?

cjihrig · 2016-06-07T00:51:30Z

LGTM, but I'll defer to @indutny, who appears to have written that code back in 2011 (3148f14).

indutny · 2016-06-07T01:11:42Z

Still LGTM
