Forgot to reset per-name penalty when it got locked by apply_decision.
This also fine tunes compare_package_preference() to always prefer
packages specified on command line speeding up calculation certain
complicated solutions.
* upgrade needs explicit check so we don't try self-upgrade
(which would print additional messages on screen)
* add can fix problems, so check against the new world
* merge the code in few places
Previously we would cache the penalty when evaluating the final
solution, and adding that until we backtrack to first topology
position changing that penalty. However, we can just keep track
of minimum penalty based on name state, and add it. This allows
us to bail out early on bad branches because we know in advance
how things will turn out.
Previously we would not upgrade just by doing "apk add foo@tag" if
foo was already installed. It required explicit '-u'. This allows
'apk add' to explicitly prefer the newly specified pinning.
Improves /etc/apk/repositories format so you can say:
http://nl.alpinelinux.org/alpine/v2.3/main
@edge http://nl.alpinelinux.org/alpine/edge/main
@testing http://nl.alpinelinux.org/alpine/edge/testing
After which you can pin dependencies to these tags using:
apk add stableapp newapp@edge bleedingapp@testing
Apk will now by default only use the untagged repositories,
but adding a tag to specific dependency:
1. will prefer that tag for the name
2. allowing pulling in dependencies from that tag (though,
it prefers untagged packages to satisfy deps if possible)
fixes#575
If two packages replace each other, the one with highes priority
will keep the file. Additionally, if we have a package overriding
another's file it's remembered and handled properly. This is
essentially to allow "policy packages" which just overwrite certain
(configuration) files from other package(s).
"replaces" is now turned to a full dependency type list, so you can
make package overwrite files only certain versions of the package
(though, we should probably take this into account already at solution
calculation phase).
Also make 'info --replaces' print the "replaces" of the package.
This is in preparation for the policy package support, which still
requires "replacement priority" field to decide which packages' files
get the preference.
The array struct aligned size to 64 bit on x86_64 which caused bad things
to happen.
We use size_t to make sure the size element is correct regardless arch.
Solution found by Timo.
allow per-name solver flags to be inheritable, and use them in
self-upgrade, add -u and the fix applet. this gives more familiar
behaviour for the upgrades.
