-------------------------------------
CLA signed and emailed.
BTW, I created a pull request on github for my changes :
https://github.com/apache/cordova-plugin-file-transfer/pull/16
So far memory handling seems fine :-)
> iOS file-transfer plugin fails to upload large files (> 200MB)

> Key: CB-5790
> URL: https://issues.apache.org/jira/browse/CB-5790
> Project: Apache Cordova
> Issue Type: Bug
> Components: iOS, Plugin File Transfer
> Affects Versions: 3.3.0
> Environment: iOS 7.0.4 on an non retina iPad mini and an iPad 3.
> Plugin v0.4.0
> Reporter: Nicolas Leclerc
>
> While trying to upload large video files (> 200MB) using the file-transfer
> plugin upload function, i get a FILE_NOT_FOUND_ERR error.
> Turns out the real error is as follows:
> {quote}
> Error opening file
> /var/mobile/Applications/1F3C6CCF-D37B-45C0-B6D2-839FA5F7C163/Documents/20140112214958-rally-vendome-aaa.session/vendome_aaa_mime_1.MOV:
> Error Domain=NSCocoaErrorDomain Code=256 "The operation couldn’t be
> completed. (Cocoa error 256.)" UserInfo=0x176ce440
> {NSFilePath=/var/mobile/Applications/1F3C6CCF-D37B-45C0-B6D2-839FA5F7C163/Documents/20140112214958-rally-vendome-aaa.session/vendome_aaa_mime_1.MOV,
> NSUnderlyingError=0x176cbac0 "The operation couldn’t be completed. *Cannot
> allocate memory*"}
> {quote}
> Smaller files work fine so it would seem that the whole content of the file
> is read into memory before uploading despite using the
> {{NSDataReadingMappedIfSafe}} option of NSData.
> I did find some reference to the fact that ios is indeed buffering the whole
> file into memory:
