Memory leak when switching between views

[christoph-thommen]

When Switching between Tabs / Views, the used memory is increased by 0.3-0.7 MB each switch.
This happens also, when the app content (ion-content) is completely blank and all functionalities within controller.js/app.js are commented out.

Hello! Thanks for opening an issue with us, we just need a little more info from you so that we can better help you with your issue. Would you mind posting a code sample, plunkr or codepen that we can use to reproduce your issue? Also, would you mind running ionic info and posting the output? Thanks again!

Hi
ionic info output is already in my previous post.
As an example you can just take an empty ionic app with tab navigation... When switching around through the views, the memory just increases

Thanks

@Pyroon, will have to do some testing of my own, Thanks! Are you using chrome dev tools to inspect memory usage?

[christoph-thommen]

Yes, but you can see it best when running the app on the iOS simulator (e.g. ipad simulator) and inspecting the memory usage with xcode.

@Pyroon Are you using any external libraries?

[christoph-thommen]

I use some plugins like those:

"com.telerik.plugins.wkwebview": { "WKWEBVIEW_SERVER_PORT": "12344", "PACKAGE_NAME": "xxx" }, "cordova-plugin-console": { "PACKAGE_NAME": "xxx" }, "cordova-plugin-device": { "PACKAGE_NAME": "xxx" }, "cordova-plugin-network-information": { "PACKAGE_NAME": "xxx" }, "cordova-plugin-webserver": { "PACKAGE_NAME": "xxx" }, "ionic-plugin-keyboard": { "PACKAGE_NAME": "xxx" }

additionally, I'm using ng-websocket

Hi @Pyroon,

Can you provide a codepen to recreate this? Let's try to limit external dependencies so we can determine if this is an Ionic issue or a cordova issue.

Thanks,
Dan

Hi
I think I found the issue. It's related to ng-repeat (angular/angular.js#11169)
Cheers

@Pyroon so are you not having the memory leak anymore? Also if you can, could your provide a plunkr or codepen that demonstrates this issue? Thanks!

[christoph-thommen]

Hi
we still have memory issues, but it looks like it's related to the angular ng-repeat memory problem. So no need to go more in detail for ionic. I think switching to ionic 2 asap would help to resolve this issue as the bug is fixed in angular 2
Cheers

@Pyroon sounds good then! Thanks for using ionic!

@jgw96 @Pyroon is this problem resolved ? it still exists on [email protected]

[cozzbie]

Seems to be an angular and not ionic issue @dig1234
