Jason Ginchereau updated CB-9652:
---------------------------------
Labels: iOS (was: )
> Cordova File plugin memory leaking
> ----------------------------------
>
> Key: CB-9652
> URL: https://issues.apache.org/jira/browse/CB-9652
> Project: Apache Cordova
> Issue Type: Bug
> Components: Plugin File
> Affects Versions: 3.5.0
> Reporter: Gregor
> Labels: iOS
>
> We are creating apps using Ionicframework, then building them using cordova.
> What we are doing in our app is taking photos using Cordova Camera, then
> moving the files to specific directory. The user has an ability to upload all
> photos taken to server. Here is how the user progresses through the app:
> 1. Make Photo using Cordova Camera.
> 2. Use Cordova File to move created file using step 1 to other location.
> 3. Repeat process 1&2 several times (20 times approx).
> 4. Start sync process
> 5. $http requests start (synchronous, not asynchronous!)
> 5.1. Read data from File as base64 string (using Cordova File plugin)
> 5.2. Send data to server
> 5.3. On success, use Cordova File to delete photo from device.
> This was tested on:
> - iPad mini (ios 8, uiwebview)
> - iPad 4 (ios 8, uiwebview)
> We've debugged the whole process through Xcode and checked how memory
> management is doing. The results were catastrophic!
> - After each File.moveTo call, the app memory grew for at least 5MB.
> - After each File.readAsDataUrl call, the app memory grew for at least 5MB.
> - After each File.removeFile call, the app memory grew for at least 5MB.

> The problem isn't when we have just a few files to move (aka 5), but having
> approximately 50 files, it always leads to an app crash. On iPad mini, after
> 10 or 15 images, on iPad4, after 30, 40 or 50 images.
> We've also tried to update Objective C code at all functions which we were
> using surrounding them with {code:java}@autoreleasepool{code} brackets. It
> didn't helped.
> We've also tried to upgrade Cordova, tried to use different File plugin
> versions, but there wasn't any difference. You kinda start thinking,.. is it
> actually any good using those unoptimized plugins? Has anyone actually tried
> them constantly running without closing the app? Has anyone actually thought
> the clients also use old devices?
> There isn't any memory management to be done on the app side, since we're
> coding in JS (using Angular). But the crashes... well... we're dissapointed
> to found out it will take few years before we'll have enough memory and the
> Cordova itself won't be such an resource hog.
> Is there actually anything we can do to 'optimize' the calls? Sadly, there's
> no File.clean() or File.recycle() function we could use to clean the cordova
> plugin memory.
> What are your suggestion?
> Regards,
> Gregor
