this makes 'lbu diff' and aaudit diffs nice when a world
dependency is added or removed. sorting also makes the ordering
more deterministic as the world targets constraints are always
applied in the same order. test suite updated accordingly.
This makes sure any conflicted packages will be removed first.
Useful if we know there are conflicting files, and want to avoid
adding potentially harmful replaces line. Add a test case for
this too.
Select latest version of package (if it is not pinned), and print
error if it cannot be installed due to other dependencies.
Together with --available, it selects the latest package which is
present at least in some repository.
This also fixes few solver issues with ordering of package selection
that got quite apparent with this flag. Namely, we cannot "lock"
a package until it's reverse dependencies are locked or not all of
the solver flags are propagated properly.
the pinning11 changed when @repo got the leading @ on error messages.
analyze_dep() now properly ignores conflict dependencies, as those
names are usually intentionally left unassigned.
Instead of the dependency oriented logic, switch to print them
for each package or name needed. Might give a bit more readable
errors now. There's still few corner cases that proper error is
not output, which are cought by the test cases.
make cache a special kind of repository, and automatically cache
special packages (virtual packages, or ones installed from command
line). add test cases for handling virtual packages. fixes#1617.
Solver will now never report partial solution where a conflict
constraint is not satisfied. The is because with --force we might
install the partial solution; and if conflicted packages were to
be installed we might have extra trouble.
Otherwise we might start to change packages unexpectedly when not
upgrading. This also fixes some other things the solver might've
decided to do.
Add also few test cases to detect bad behaviour.
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.
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.
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
Allow to select packages that conflict in case we are looking for
errors. This allows 'add --force' to install (on boot) the set of
packages with minimum conflicts.
