Crash / Entire window goes blank - in projects using Ionic #7262

Switching back to sprint 36 in the meantime. Very weird! |
|
Ack, that's terrible. Next time it happens, can you try (from Chrome) going to |
|
Sure I'll install 37 side-by-side with 36 and share what I find ... |
To do this, install Sprint 36, then make a copy of the entire Brackets install folder, then install Sprint 37 (which installs over Brackets folder). |
|
@redmunds sorry I don't quite follow. Right now I have Sprint 36 and Sprint 37 separately in my Applications folder (this is Mac OS X). Is that what I want? |
|
BTW just noticed some of my extensions were out of date. I've updated them, let's see if that solves it. Will post any failures here. |
|
That's perfect. I missed that you were on Mac. |
|
OK this is weird. Screen went blank, then I went to |
|
We've heard reports of this problem, although it's rare and it has been a while, but since it's so nasty we'd love to try to nail this down. Can you provide a set of reproducible steps that makes it happen every time? That would help us to track it down. Thanks. |
|
Also, see if you can reproduce it with no extensions installed. You can use Debug > Reload Without Extensions to quickly run without extensions (and restarting Brackets returns to loading of extensions). If that eliminates problem, then try to isolate which extension is causing problem. |
|
Just crashed again. Had Chrome dev running at the time and it says "Inspected target has crashed. Once it reloads we will attach to it automatically." Will try with no ext. This is sprint 37. |
|
Yikes. Just crashed again, this time with extensions disabled. Chrome gave the same "Inspected target has crashed. Once it reloads we will attach to it automatically." msg. Still working on reproducible steps but right now it seems like

OK I'm getting it to crash pretty consistently. I'm thinking it's this particular javascript file I'm working in. Confirmed that there is no useful information coming up in the Chrome dev console. I'm gonna try to isolate if there's a particular part of the code in this file that's causing the problem. |
|
What version of Chrome are you running? Switch to stable if you are running something else. |
|
Version 33.0.1750.152 (stable). I do have Chromium installed as well ... |
|
@boozedog Can you open up Activity Monitor on the side and see (a) if Brackets memory usage keeps climbing before it goes white, and (b) if Brackets CPU usage is high even when it's just sitting idle? Also, are you able to share the source code of the project you're working on? (You can send it directly to us privately if you don't want to post it publicly anywhere). |
|
This sounds a lot like #7245, but it could wind up being a totally different repro case (even if both wind up being Tern-related)... |
|
@peterflynn yeah actually it's Brackets Helper that goes way up in CPU and memory. Brackets itself stays low ... ?? |
|
Weirder and weirder. If I flip from one JS file to another, the BH CPU/mem usage keeps building. If I switch to an HTML file, it immediately drops back down. Also, this is happening when I open any JS file in this project. It's an ionic app I'm working on.' Will play more with this later this evening ... |
|
@boozedog How large is your project -- number of JS files, number of bytes of JS code overall? Do you have a lot of node_modules or other 3rd-party libraries in your project? |
|
This is an client-side project using Ionic which is a framework built on Angular. Total of about 150 .js files including all the libraries. I'm having trouble figuring out the total number of bytes, there are several very large files in Angular and Ionic but I'd guess at least 10 megabytes? |
|
OK so I tried the .jscodehints and excluded the directories with large library type .js files in them and that seems to solve the problem! I'm able to work with my .js files and no wacky CPU or memory usage! |

changed the title
|
A user named "fels_zh" on IRC just reported a crash with a project using Ionic also -- changing title of bug to clarify that this is the common thread (was: "Entire window goes blank!") |
|
I've just done some investigation of this specific issue. I can reproduce the crash, but I haven't tracked down precisely which file is to blame. |
|
Sounds promising -;) On May 2, 2014, at 7:00 PM, "Kevin Dangoor" <[email protected]mailto:[email protected]> wrote: I've just done some investigation of this specific issue. I can reproduce the crash, but I haven't tracked down precisely which file is to blame. ionic.bundle.js appears to not be to blame, because the JS code hints code doesn't send files greater than 512K over to the hinting engine and ionic.bundle.js is bigger than that (and I was able to see that the code hints was correctly noting the size of that file). I'll dig around some more. Reply to this email directly or view it on GitHubhttps://github.com//issues/7262#issuecomment-42093512. |
We've had a number of people report problems with Ionic in their projects. Tern appears to have an issue with the minified Ionic files. I had planned to add default exclusions so that we could quickly solve pain like this and this problem appeared to be a good candidate. The repro steps [reported here](#7262 (comment)) are fixed with this change.
|
I was better able to troubleshoot this with the new CEF and discovered that Tern was having trouble with all of the Ionic minified files. One bit of low hanging fruit in the plan for code hints that I'm working on was to ship some default exclusions with Brackets when we hear of a specific file (or files) that are commonly causing people pain. I've implemented that in #7739 with all of the ionic minified files excluded and found that things look much better. |
|
This is now fixed in master by automatically ignoring the minified Ionic files. |
|
I forgot to mention is that if you don't do the Since I normally don't use Ionic and the But since I've been following this wanted to at least add the detail since the fix (#7739) appears to be excluding file and wasn't sure which copy was going to be excluded. For the problematic ionic sample, I have the following files: In #7739 @JeffryBooher said "I was able to reproduce this eventually with the steps listed in the issue on Mac but the steps don't work on Windows.". Without a Mac and Xcode, there also would not be multiple copies of the same complex Ionic JS file within the project as well. |

@shafdog good point. The problem I was running into on Windows was I couldn't get the |
|
@shafdog I'll need to re-test my fix. When I switched from regex to glob for the new preference, I inadvertently dropped ionic.bundle.js, only getting the .min.js files. Thanks for mentioning that. I'm going to reopen this bug in the meantime. |
|
OK, I just retested with the code in master and the project works fine, so it appears that it was the minified files and not the bundle.js file that caused the issue. |
|
In addition to widen/fine-uploader which I've mentioned before, I've just nailed down another library which causes this problem: crypto-js hosted on Google Code. |
|
@tomekwi Thanks for the info. We made a change in Release 0.41 which should prevent Brackets from crashing -- have you tried it with 0.41? |
|
Thank you. Next week I'll have an opportunity to test it, I'll let you know. |
|
Same here for Firefox and Ubuntu... |
|
Hey Guys, It is happening with me now. Release 1.8 build 1.8.0-17108 (alf_localization_release_1.8 3af64fa) Just today crash 5 times. I work from a mac, El captain OS. This start right after the atualization for 1.8 |
|
I have the same problem OSX 10.11.6, Ionic 2.1.18. Brackets 1.8.0-17108 |
I'm running sprint 37 on Mac OS X 10.9.2 . The entire Brackets window goes blank eventually, and at that point I'm not able to even quit the application, must Force Quit in Finder.
