[pacman-dev] [bug?] pacman 3 doesn't check for free space in /var/cache/pacman/pkg/

[bardo]

Hi.

I looked at the Flyspray and it seems this hasn't been seen before:
pacman doesn't care if it has enough space to copy the downloaded file
from the temporary source, and sometimes it fails. POC follows (I
filled up my /var on purpose, then tried to install a package that
wasn't in my cache).

<code>
[root at damocles ~]# df /var/
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sdb6              3092380   3092380         0 100% /var
[root at damocles ~]# pacman3 -S openvpn

As you may notice, the package is actually downloaded, then marked as corrupted.
