Thread dumps
Add some thread dumps. reassigning to javascript I guess this is a duplicate of https://netbeans.org/bugzilla/show_bug.cgi?id=239185 Any update on this? Literally can't edit any file with JS in it. NB can't even scroll the file smoothly. Also just got a Out of memory error. (Can't upload the file, I have tried before. I'm pretty sure its too big as I have 3GB ram assigned to NB.) Also it would be nice if I could just totally disable JavaScript support in NB, so I can at least continue to use NB when there is an issue. Which build do you use? Could you try the latest dev build. I have made some changes that should improve the situation a lot. Thanks Tried dev build 201401090002. Just opening a JS file causes NB to become totally unresponsive. Then its memory blew up (increase by about 1GB within a few seconds). And finally crashes with OOM error. Attached some thread dumps, with the OOM at the end. Created attachment 143877 [details]
More thread dumps
@Petah: Could you please attach the js file? Also could you please try to switch off the navigator window? Thanks. I can't attach that particular file I used in the last case. There are many similar files here: https://github.com/PANmedia/raptor-editor/tree/master/src Tried it with some of those and same thing happened (I opened a few files including src/components/layout/hover-panel.js). Im kinda thinking it might be struggling with my prototypes (but don't quote me on that). By turn of the navigator window do you mean close it? I closed it and then opened src/components/layout/hover-panel.js but same effect. NB still crashed with OOM. I have cloned the repository, created new Html5 Application project with existing sources, where the src folder was chosen as the root folder. I have played with it for a while, open every file, but didn't run in any problem. It would be great, if we can find steps how to reproduce. My questions? - Has the background scanning finished? - How many files do you have opened? - Could you run the ide with the options: -J-Dorg.netbeans.modules.javascript2.editor.parser.JsParser.level=FINE -J-Dorg.netbeans.modules.javascript2.editor.level=FINE and attache the var/messages.log file, when the problems happened. Thanks. Yes background scanning is finished, I opened NB, and didn't touch it until it was not showing in the running tasks at the bottom of NB. It happened even with 1 file open. Started NB with these options: netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-Xmx3200m -J-XX:+UseConcMarkSweepGC -J-XX:PermSize=32m -J-Dnetbeans.logger.console=true -J-ea -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.java2d.dpiaware=true -J-Dsun.zip.disableMemoryMapping=true -J-Dplugin.manager.check.updates=false -J-Dnetbeans.extbrowser.manual_chrome_plugin_install=yes -J-Dorg.netbeans.modules.javascript2.editor.parser.JsParser.level=FINE -J-Dorg.netbeans.modules.javascript2.editor.level=FINE" I have attached the message.log and a screenshot.

Screen Shot
Also note that, in the screenshot, you can see where I open the JS file the memory ramped up from about 1.3GB to 3.2GB in a matter of seconds. Any updates on this? In the message log file there are many exceptions, that some files are locked during scanning. Were some files open in another tool / editor? Could you please upload zipped heap dump (C:\Users\David\AppData\Roaming\NetBeans\dev\var\log\heapdump.hprof.old) here: <http://deadlock.netbeans.org/job/upload/build>. Thanks. I can try again to upload a heap dump (will have to be next week), but I have tried before and it fails. Even the zipped heap dump is like 700MB, which would take like 9 hours on my connection to upload. It is possible that some files/directories could be locked. Windows Explorer and the Console does acquire locks, and would have been open. |
