Subject: Bump debian control.tar size limit
X-Git-Tag: 0.6.35~45^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d85442d05de4f2c33e692f4815dbd06f46e3fdb8;p=thirdparty%2Flibsolv.git

Bump debian control.tar size limit

Increase the arbitrary control.tar limit from 1 MB to 16 MB. We came
across an openjdk-7-jdk package that had a 2.4MB control.tar.gz and
libsolv failed to parse it. dpkg doesn't actually apply a limit to these
files.
