Date Thu, 01 Aug 2013 12:45:48 GMT
Klaus Schmidt created CB-4480:

             Summary: CDVFileTransfer - handling big files >2GB is not correct
                 Key: CB-4480
             Project: Apache Cordova
          Issue Type: Bug
          Components: Plugin File Transfer
    Affects Versions: 3.0.0, 2.9.0
         Environment: iOS in general
            Reporter: Klaus Schmidt
            Assignee: Steve Gill
         Attachments: CDVFileTransfer.h.diff, CDVFileTransfer.m.diff

Hello Cordova Team,

we needed to download big files (>2GB) via FileTransfer and use the onProgressEvent to
display the progress.
On Android everything is fine. On iOS the reported sizes in the onProgressEvent are not valid,
if the downloaded file is larger than 2GB:
{{CDVFileTransfer}} uses {{NSInteger}} for {{bytesTransfered}} and {{bytesExpected}}. {{NSInteger}}
only is up to 2G-1 as mentioned here:

We patched library of version 2.9.0 to use "unsigned long long" - now we are able to display
downloads up to 16Exabytes-1byte correctly. We see in github, that 3.0.0 has the same issue.

I will add the diff in the issue after creating it.
