I'm afraid this patch is basically impossible to review. There are
warning signs like the inclusion of the binary swo file. The hint that
code gets duplicated also worries me, even if you abstract this, there
shouldn't be reason to do that.
If we do this its going to have to be a more granular series where the
patches *just* move code to new locations so we can see/understand what
other changes are being made as I simply don't trust this patch, sorry
:(.
Cheers,
Richard
Hi,
sorry about the swo file that's a mistake on my side. The duplicated code is
simply so that deb and ipk shares a class. So my choice was to either duplicate
that class (and let them diverge which is fine) or in the core
package_manager.py file have a class that is not used by all package managers
(rpm doesn't use it).
This patch is only code moves and class renames. I know it's very hard to
review, that's a real problem. Let me see if I can split it up some more.
BR
Fredrik
