Python apt: Multiple instances of Cache and DepCache

["Karichery, Sreeraj" <Sreeraj.Karichery@deshaw.com>]

Hi,

 

I’ve started playing around python apt libraries and trying to see if we can have multiple instances of Cache and DepCache available as references living at the same time.

 

I have reinit the DepCache and use that again, but I was looking for comparing the DepCache for different operations performed.

 

Eg: I’m trying to implement something like this:

 

                # Setup cache using some set of sources

                c1 = apt_pkg.Cache()

                dc1 = apt_pkg.DepCache(c1)

                dc1.mark_install(pkg1)

               dc1.mark_install(pkg2)

 

                ….

                # Create a fresh cache again (using different set of aptsources)

c2 = apt_pkg.Cache()

dc2 = apt_pkg.DepCache(c2)

dc2.mark_install(pkg1)

dc2.mark_install(pkg2)

 

                # Custom build function

compare_depcache(c1, c2, dc1, dc2)

 

Thanks
