Package: libsbuild-perl Version: 0.78.1-2 Severity: normal X-Debbugs-Cc: vagr...@debian.org
Dear Maintainer, Forenote: I'm Cc'ing vagr...@debian.org because he reported a related issue to this one and the fix for this issue might impact him. I'm using a slow internet connection and, when repeatedly testing a package I've modified with sbuild, it takes a long time downloading packages for dependencies of the built package. So I've made the /var/cache/apt/archive directory persistent in the schroot by binding it to a directory on the host. So downloaded packages by apt are kept even after the schroot session is ended. But, even if I disable "$apt_clean" option, sbuild always download dependencies packages at each invocation. I've found in "/usr/share/perl5/Sbuild/ResolverBase.pm", that sbuild is using APT::Keep-Downloaded-Packages "false" This makes all downloaded packages by apt deleted after installation. As this apt option is used unconditionally, sbuild always download, install dependencies for the built package and then delete the downloaded packages from the cache at each invocation. APT::Keep-Downloaded-Packages option was introduced to fix this bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=861762 I suggest to set `APT::Keep-Downloaded-Packages` to "false" only if the option "$apt_clean" option is set to 1, else set it to "true". The current description of the apt_clean option is: APT clean. 1 to enable running "apt-get clean" at the start of each build, or 0 to disable. If accepted, I suggest to amend this description accordingly. I can provide a patch if this solution is accepted. What do you think about that solution ?
