Subsonic Forum

I have a problem when downloading larger files (4.4gb). I have tested subsonic with some video streaming, but it seems that downloading is a problem.
It starts downloading, but the filesize is set only to about 381mb for a 4.4gb file and if I stream the movie it stops about 10 minutes in. I seems that the problem is the filesize is an 32bit variable and should be 64 bit, but im not that much into programming, so it could be something else.

The system is a ubuntu system and using apache_tomcat as host application.

When i try to download it with the zip function i get this error which only supports the problem.


Exception java.lang.IllegalArgumentException
Message invalid entry size
Java version Sun Microsystems Inc. 1.6.0_07

Java.lang.IllegalArgumentException: invalid entry size at java.util.zip.ZipEntry.setSize(ZipEntry.java:135) at net.sourceforge.subsonic.controller.DownloadController.zip(DownloadController.java:314) at net.sourceforge.subsonic.controller.DownloadController.downloadPlaylist(DownloadController.java:227) at net.sourceforge.subsonic.controller.DownloadController.handleRequest(DownloadController.java:115)

And so on.

Thanks in advance

It turns out that this is a bug/feature in Java.

The method javax.servlet.ServletResponse.setContentLength(int) has a 2 GB maximum:

There is fortunately a work-around that I will use:

Regarding the zip error, it turns out that it has a limit of 4GB, according to wikipedia. There is a "ZIP64" format extension to get around this, but that is apparently not included in Sun's implementation.

Anyway, I'll implement the setContentLength work-around in 3.6, and hopefully that will solve your issue.

Thanks for reporting it!
