[Bug 412413] Re: zsync 32bit cannot download DVD

[psl]

I replicate the issue at my test server. I have a huge test file with
random data at my local WWW server and I try to get test file (filesize
2202009600)  with zsync running at 32-bit Ubuntu system. From http
traffic, it looks that zsync fails to request more than 2147483647 bytes
from the server. Is the bug in embedded www client in zsync? I think
that 64-bit system will request wider range (Range: bytes=0-2202009599).
Is this hint useful to fix this bug in zsync?

zsync client exits after downloading 2147483647 bytes from www server,
it doesn't try again and again. End user has to download the rest of
file (or the whole file) in other way. :-(
