Brackets version 27 halt on Windows 7

[hectorfhurtado]

Hi,

First of all, thanks for this awsome editor.

Second of all, with this new release ( 27 ), from time to time Brackets just halts and the content panel is turned into a light blue color and no button has effect, not even the red top right button to close it, I have to force the exit on Task manager. I don't know how this is triggered, It just happens.

I'm running Brackets on a Windows 7 machine.

This is a screenshot:

Thanks in advance.

@hectorfhurtado i also ran into this issue today.
I noticed that in the moment, when brackets starts to hang some brackets process just used an awfull lot of memory. But i couldn't reproduce the error at the moment. The only thing i noticed was, that the Brackets process seemed to use much memory, which increased with nearly every file i opened.

Hi, oh yes, when I just opened brackets, It consumed 57MB, but, when I started changed between files ( with Ctrl + Tab ), memory consumptions went to 125MB in 10 seconds more or less. I had opened 6 files and I was looping on these.

High Priority. This isn't related to #4394.

@hectorfhurtado and @WebsiteDeveloper - this sounds like it might be the same issue as #3977. Are you using any particular large JS libraries (e.g. Angular) in the projects that you have open when Brackets hangs? If so, please let us know as that will help us narrow down the problem.

[njx]

High priority for sprint 28. Tentatively assigning to @dangoor since it sounds like these might be more Tern-related cases.

@njx, I have similar problem too. I use Brackets to develop my company projects, which contains a large set of javascript file. Once updated to 27, It get around 10 seconds to open a file, any type of files.

update: not only open files, It needed to be wait also in switching the files on Working Files

[hectorfhurtado]

HI, I'm using polymer and a bunch of node modules, but I've noticed that Brackets hangs when I have various opened files on my Working Files area and if I don't save on my current file and jump to another It just stops working. That exactly happend to me yesterday, very frustrating on that moment :) I'm back on release 26

[dangoor]

From the look of it, I think you're right @njx. I'm going to start digging in now with one of the known failure cases.

[dangoor]

@hectorfhurtado To help me reproduce this, would you mind telling me which Polymer files are in your project and what dependences/devDependencies you have in package.json for node? I'd like to try to set up something as similar as possible to see the behavior.

Here's what I have seen so far... I threw all of Polymer's .min.js files into a directory (just to be rough on the code hinting system). I installed express into node_modules, knowing that that comes along with a number of files (124 .js files in node_modules).

If I use cmd-tab to switch between files a bunch, the CPU works hard for a few seconds but the app never becomes unresponsive. I do see memory usage climbing as I do this. The brackets-helper process on my Mac is now at 738MB, up from 590MB before my last handful of cmd-tab switches. Given that each of the 6 Polymer files I have is more than 100K, this test is probably a bit harsher than reality, which is why I'm interested in knowing more specifically which libraries you have.

[hectorfhurtado]

Hi, these are mi dependencies on node:

"dependencies": {
"express": "3.1.0",
"jade": "*",
"mongodb": "~1.2.0",
"socket.io": "~0.9.0",
"ssh2": "~0.2.5"
},
"devDependencies": {
"grunt": "~0.4.0",
"grunt-contrib-copy": "~0.4.1",
"grunt-contrib-concat": "~0.1.0",
"grunt-contrib-compass": "~0.1.0",
"grunt-contrib-coffee": "~0.7.0",
"grunt-contrib-livereload": "~0.1.0",
"grunt-contrib-uglify": "~0.2.0",
"grunt-contrib-watch": "~0.3.0",
"grunt-contrib-yuidoc": "~0.4.0",
}

From polymer, I'm using polymer.min.js and web-animations.js; but in total my project has 13.323 files, because I have a bunch of MIBs, scripts that act as agents, sass files, etc.

I don't know if Brackets actually tries to scan all of these files or just the ones I'm using on the working space. If Brackets is looking at all, is there a way to hide from brackets unrelevant files?

Thanks in advace

these are some detail of my machine:
Processor: Intel(R) COre(TM) i5-3320M CPU 2.60 GHz
RAM: 4.00 GB (2.89 GB usable)
System type: 32 bits OS

I can reproduce the hang with web-animations.js on my Windows 7 before getting changes from this pull request #4439. So I believe changes in Tern also fix the hang issue that can be caused by web-animations.js.

Update: Actually, I started out with ExtJS and switched to web-animation.js when I got the hang. So it may not be the web-animations.js.
