Bug Description
Binary package hint: zsync
Ubuntu 9.04 i386, zsync 0.5
zsync cannot download DVD image of Ubuntu (karmic-
To test it, try command like this one:
# zsync http://
In the case that zsync has this limit by design, it should warn the user that it cannot download such huge file and give up. Better way is to fix zsync to don't have such limit...
SRU JUSTIFICATION: zsync on i386 is currently broken on i386 for all files over 2GB. The larger the file, the more important it is that we have reliable and robust methods for optimizing download times, and we have common files now over 2GB in size - DVD images.
REGRESSION POTENTIAL: we could break zsync support for files less than 2GB in size on i386 (worth the risk), or we could break zsync support on amd64 (very unlikely).
TEST CASE:
- run zsync on i386 against http://
- observe that everything about this is broken, including the download time, the reported file size, and (eventually) the downloaded image, which will be truncated at 2GB.
- upgrade to zsync from -proposed
- run zsync again against the same partially-
- verify that the md5sum is correct at the end of the download by comparing with http://

I retested with Ubuntu 9.04 amd64 and zsync 0.5. I can download DVD image in 64-bit Linux, bug is isoloated to 32-bit code. Thisis good news...
I tried to generate zsync file for DVD ISO image under Ubuntu 9.04 386 and Ubuntu 9.04 amd64 and I get the same file in both cases. This is great.
My conlusison is that only zsync client in 32-bit Linux has some bug that limits it use to some small ISO images (CD is OK, DVD is too big).
