Details

If a souce file name has space in it's name, bsdtar treats it as two separate parameters.
If it has '%' in file name, a printf used to print makepkg progress expects additional parameters and build fails, too.

Example: try to build a package with source like:
http://opendesktop.org/CONTENT/content-files/50534-fedora%20core%206%20inverse.tar.gz or
http://opendesktop.org/CONTENT/content-files/50534-fedora core 6 inverse.tar.gz
This task depends upon

Does it work if you escape those characters? i.e. \%

We need to be more careful when creating our cmd in the extract_sources() function- we don't quote the $file variable there, so spaces will definitely break things. Attached is a patch to fix the spaces issue.

And the second part, not too hard at all. Fix cases with escape sequences in filenames.

@Allan: nope, I doesn't work with any possible combination of {doublequote,singlequote,no quote}x{%20,space}x{no escape,escape before %20 or spaces}
(where 'x' is cartesian product :)). Every time it fails either downloading, bsdtar or printf.
I haven't tried Dan's patches yet.

Signoff on both patches.

Looking into this further, those patches fix the case with "%20" but not with raw spaces. That still fails on download. But manually wget the file with spaces in its name and it extracts fine.

I can partially fix the spaces in file names issue by adding escaped quotes around the file name and url when generating the dlcmd command in download sources. Only problem is I end up with this:

dlcmd="/usr/bin/wget -c -t 3 --waitretry=3 -O \"50534-fedora core 6 inverse.tar.gz.part\" \"http://opendesktop.org/CONTENT/content-files/50534-fedora core 6 inverse.tar.gz\""

$dlcmd || return $?

Doing an "echo $dlcmd" and copying and pasting the output works, but the line running $dlcmd fails. wget trys downloading multiple files, splitting at the spaces.

bah... eval...

The attached patch complete the fixes needed for this bug. All patches are on my working branch.
