xdelta3: non-seekable source in decode: XD3_INTERNAL

[GoogleCodeExporter]

Running xdelta3 3.0y on some of (bigger?) Arch's packages fails with 
"xdelta3: non-seekable source in decode: XD3_INTERNAL". The last version it 
works okay with is 3.0v2.

With 3.0y: 
xdelta3 -d -vv -s wine-1.1.40-1-i686.pkg.tar.gz wine-1.1.40-1_to_1.1.41-1-

Playing with -B has no effect. Unless it's PEBKAC.

Mentioned files available at 
http://www.schlunix.org/archlinux/extra/os/i686/wine-1.1.40-1-i686.pkg.tar.gz 
and http://archdelta.net/extra/os/i686/wine-1.1.40-1_to_1.1.41-1-i686.delta

The same happened to me when trying to create a delta of the jre package.

At me similar problem. Arch Linux and xdelta3 3.0y too.

How large a value for -B did you try?  As documented in 
http://xdelta.org/2009/10/re-3.html, there is a normal case for this error.  
You should raise the value for -B until it goes away, but keep in mind that 
this problem would not happen normally, it's a result of the delta being 
generated by a pre-3.0y binary being applied by 3.0y.

Who is in charge of the archdelta.net site?  I'd like to know how they choose 
which version of xdelta3 to use, as I'd really like people to upgrade to 3.0y.  
These problems will go away (I think) when both encode and decode are using 
3.0y or later.

I believe I tried different -B values, including the highest possible, without 
success. 

Quoting from the archdelta maintainer's original post ( 
https://bbs.archlinux.org/viewtopic.php?pid=717016#p717016 ): "I'm using 
xdelta3 (3.0v-2) because the 3.0w version has a bug where it doesn't decompress 
input files correctly (netting a delta thats almost the same size as the 
package)."

I filed issue 113 about the failure related to -B.

However, I would like archlinux to upgrade past 3.0v and will post again on 
that forum.

FYI, the version currently present in Arch repository is 3.0z.

Release 3.0.0 fixes this issue and the related issue 113.  Thanks.
