> Memory leak in loading files from disk with file plugin
> -------------------------------------------------------
>                 Key: CB-8332
>                 URL:
>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: Plugin File
>    Affects Versions: 3.5.0
>         Environment: iOS
>            Reporter: Patrick Richards
>              Labels: iOS, memory-leak
> When loading files from disk, the file plugin appears to leak memory. Using instruments
it can be narrowed down to -[CDVFilesystemURLProtocol startLoading], which is in CDVFile.m
on line 150.
> (
> To reproduce:
> • have the iOS app download a file using plugin-file-transfer
> • store that file to persistent storage
> • load that file from disk and the app will leak
> We have a very simple proof of concept that downloads a large photo, then constantly
refreshes an iFrame which triggers loading the photo from persistent storage. The memory usage
of the app climbs over time (with various dips at memory warnings), then crashes due to memory
pressure. We can upload this sample project/provide a link if needed – there doesn’t appear
to be a way to attach files.
