[CLOSED] Intermittent WSOD when editing brackets Gruntfile.js

[core-ai-bot]

Issue by jasonsanjose Tuesday Jul 23, 2013 at 19:00 GMT Originally opened as https://github.com/adobe/brackets/issues/4549

1. Sync to jasonsanjose/grunt-hack-setup (branched from master 830c83c2adc07220c0624e7806fb58dbecd50155 as of this morning 7/23)
2. Open brackets project
3. Open Gruntfile.js
4. On line 171, begin typing if (grunt.file.exists(path)) {
5. Observe crash

I've had varying success reproducing this crash. It might depend on how quickly you begin typing after Brackets starts up and/or whether or not the Gruntfile.js was already in the working set.

I was able to reproduce on mac and windows. If it didn't reproduce right away, making simple edits like backspacing to retype the line seemed to do the trick too.

To me for now. I got some tips from@dangoor on how we could try to track down another workaround.

This is a small point, but this crash also reproduces without the original workaround. (I just wanted to check that to make sure that this isn't actually a regression caused by the original workaround.)

On the assumption that this is another V8 crash in Acorn, I tried to narrow down the crash by writing a Brackets extension that simply runs acorn on every .js file in a folder (recursively), and pointed it at the Brackets folder. Unfortunately, I couldn't get it to crash. I also couldn't get it to crash on polymer.min.js (with the version of Acorn that doesn't have@dangoor's workaround), though, so there must be something else that I need to do in order to trigger even the original crash. Tern doesn't pass any special options to Acorn, though, so it's hard to imagine what that would be.

@gruehle mentioned that the original crash happened when rescanning the same file after small changes a lot of times, so I tried having Acorn scan each file multiple times in a row, but that still doesn't trigger the original crash in polymer or in the brackets codebase.

My original reason for trying this approach is that I can't easily use console.log() to figure out where the crash is in the normal course of running Tern/Acorn within Brackets, because console.log() isn't available in web workers. I tried posting log messages back to the main thread, but I don't think I was getting good data from that approach, probably because the final log message didn't actually make it before the worker crashed.

@dangoor suggested hacking JS code hints so they don't run Tern as a worker, but I couldn't find a quick way to do that. (I looked at a web worker polyfill that simulates the worker with setTimeout(), which would be perfect for this purpose, but it doesn't work with importScripts(), which is necessary for require.)

It might not take that long to hack the worker and the host in ScopeManager to replace postMessage()/addEventListener() with a direct call mechanism...I have to leave for the day but might look at that next, see if I can hack that up in a short period of time.

I've found steps that will reproduce this in master, so it's not related to any of the other changes in this branch:

1. Copy the following to the clipboard:

function foo(path) {

}

1. In Brackets, open Gruntfile.js
2. Place the cursor on line 167
3. Paste
4. Click in the blank line inside foo() and type grunt.file.exists(path) - crash

If I type the function wrapper instead of pasting it before typing the call to grunt.file.exists(), I can't get the crash to happen. Also, the crash doesn't happen if I just type grunt.file.exists(path) directly into Gruntfile.js without the function wrapper around it.

I'm not sure that tells us anything :), but at least we have a slightly reduced repro case in master.

Try the glenn/cef-3.1547.1337 branch in brackets-shell and see if the crash still reproduces. This is a new CEF that integrates Chromium 29.

Crash doesn't appear to occur in that branch, as expected, though I've only tried my smaller repro case so far.

I now have a branch that runs Tern in the main thread, but I can't get the crash to occur in that branch (either Jason's original or my reduced version) :( So it's possible that this is actually a different problem that's related to the worker. It could actually be a bug in workers, or it could just be that because the asynchronicity is different, something else changes that avoids the crash.

It would be interesting to try to reproduce the original crash@dangoor's workaround fixes in this branch, but I don't know how to do that (there was a link in that bug that appears to have been a recipe for reproducing it, but the link was removed).

Progress: the immediate cause of the crash is src/utils/KeyEvent.js. If I remove that from a copy of the Brackets project, I can't reproduce the crash.

UPDATE: Red herring. It seems like I can reproduce it even if that file is removed now.

I haven't reproduced the crash in the cef-3.1547.1337-remove-acorn-fix8516 build so far on mac. I'm using the latest branch version that@gruehle says fixed the separate 10.6 crash. I'm on 10.7.

Closing since the upgrade to CEF has landed in master and@jasonsanjose has confirmed the crash no longer occurs.

I'm going to reopen this since we're still tracking which CEF version we're going to ship.

I've been working on finding a workaround for this. It is difficult because the crashing code is in a web worker and if we try to use the debugger on the worker, the code doesn't hit the optimizer (and therefore doesn't crash). And the worker doesn't have console.

What I have seen consistently is that the worker receives a GetFile message for WorkingSetView-test with 0 bytes of text.

Worker: Parsing ../test/spec/WorkingSetView-test.js 0 ScopeManager.js:1067
Worker: Returned from parse0 ScopeManager.js:1067
Worker: 106 files remaining ScopeManager.js:1067

The handling of WorkingSetView-test.js appears to run fine. The worker does not send any messages back to the main thread after that, though. My theory is that the worker is dying before it actually has a chance to post the messages back.

After WorkingSetView-test is sent into the worker, the main thread loads up a handful of additional files, the first of which is widgets/bootstrap-dropdown.js. That's the first of 19 files that are loaded and posted to the worker, but the worker never logs the receipt of any of them.

My guess is that it's crashing when parsing bootstrap-dropdown.js, but I haven't yet figured out a way to narrow it down more than that. Since this crash is so reproducible, perhaps the next step is to just start selectively forcing functions in Acorn to not optimize (through the eval(true) trick used in the next function there).

Yup, that's all very consistent with what I was seeing on Wednesday.

I have a workaround for this crash in the dangoor/v8-crash/redux branch. I have added eval(true) to every function in acorn.js as a way to force the v8 optimizer to turn off. I was easily able to reproduce the crash using Jason's reported steps before the workaround and could not reproduce it after the workaround.

I did some performance tests this morning and found that when parsing polymer.min.js, acorn took on average about 13% longer to parse (median was 9% more) after adding all of the eval(true)'s.

That's not to bad, how certain are we that this addresses the bulk of the potential crasher?

Comment by dangoor Monday Jul 29, 2013 at 16:41 GMT

So far, all of the crashes that I've seen with the sprint 27 shell (including the one in this bug) have been caused by v8's optimizer on Acorn. It is certainly possible for v8's optimizer to fail on some other piece of code, but it appears that there's something specific in Acorn that triggers this bug.

Barring reports of some other crash, this workaround seems to do the trick.

Do we want to keep this open until we merge the new CEF? (I guess in some sense it was already closed due to the workaround...)

Comment by dangoor Saturday Aug 10, 2013 at 03:20 GMT

Seems fine to me to close it given that we have both a new CEF that appears to work and a workaround if it doesn't.
