2017-12-12solver: fix potential install_if processing failure, fixes #8237Timo Teräs2-0/+28
In discovery phase, there was logic to not process packages multiple times. However, that logic failed to account the package's depth and install_if state for the name being processed. This caused install_if processing failure in certain topologies of the dependency graph. Adds also a test case that should catch this issue reliably.
2017-11-02solver: prefer highest requirer count above installed statusWilliam Pitcock1-2/+3
This ensures a swap is emitted when replacing a virtual with apk add.
2017-11-02solver: only select a default if there is at least one provider with a ↵William Pitcock2-1/+25
declared provider_priority
2017-11-02solver: implement support for choosing default virtualsWilliam Pitcock5-4/+24
By introducing a new package metadata field, `provider_priority` (index letter `k`), we can specify default packages to satisfy a virtual. If a user wishes to select an alternative provider for the virtual, a changeset swapping the default provider for the selected provider will be generated by the dependency resolver.

2017-04-28test: add test for bug fixed in commit ba7b50c0Timo Teräs3-0/+22
2016-07-22upgrade: improve self upgrade functionality a bitTimo Teräs9-1/+121
trigger it only if apk-tools can be upgrade, add test cases
2015-01-30sort world dependencies alphabeticallyTimo Teräs4-14/+14
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.
2014-10-06solver: enforce conflicts during upgrades and new pkg installsTimo Teräs3-0/+50
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.
2014-05-19solver: fix installation of non-repository packages during tmpfs bootTimo Teräs1-0/+8
allow packages in the cache's installed to be selected for installation by the solver. add test case for the issue.
2014-05-19test: improve loading of repositories, fix broken install-if testTimo Teräs1-0/+8
2014-05-19del: allow deletion of world dependency when it is not installedTimo Teräs1-0/+7
this happens e.g. after tmpfs boot when not all packages where available: the dependency is in world, but not installed.
2013-09-06solver: if pinning is specified, it overrides preferred reposTimo Teräs3-0/+19
add also a test case for this
2013-06-20commit, db: make file conflicts and script errors non-fatalTimo Teräs3-4/+4
fixes #1482
2013-06-19solver: properly order deletion of unneeded packagesTimo Teräs4-2/+49
2013-06-19upgrade: new option: --latest (-l)Timo Teräs3-3/+28
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.
2013-06-18errors: fix a test case, and misanalysis of certain namesTimo Teräs1-1/+1
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.
2013-06-18errors: improve analysis for virtual packagesTimo Teräs2-1/+7
if all packages named N provide the virtual package, list only the name N instead of all packages providing it.
2013-06-14errors: detect self-conflicts properlyTimo Teräs2-2/+7
and add the provided version information to the conflicts. fixes the final test case that was broken. hooray.
2013-06-13solver, errors: fix few additional test cases and clean upsTimo Teräs3-3/+5
2013-06-13errors: rewrite the logic how errors are reportedTimo Teräs12-20/+74
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.
2013-06-13solver: prune broken world dependencies with --forceTimo Teräs3-0/+23
mostly useful for reboot, when all packages are not available.
2013-06-13solver: rewrite as deductive solver -- pinning supportTimo Teräs16-24/+70
Fix also pinning test cases to be more sane.
2013-06-13solver: rewrite as deductive solver -- per name flagsTimo Teräs6-0/+55
Handle properly per-name preference flags, and add test cases for testing those via fix applet.
2013-06-13solver: rewrite as deductive solver -- core featuresTimo Teräs8-8/+8
Implementing basic dependency handling, install_if and awareness of pinning.
2013-05-30db: unify handling of special packagesTimo Teräs2-0/+14
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.
2012-10-09test: fix conflict2 expectation after solver changesTimo Teräs1-1/+1
The 'a' package is now more preferred which actually makes more sense.
2012-02-29solver, test: make conflicts unconditionalTimo Teräs1-1/+1
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.
2012-02-28solver: consider provided names also for preferenceTimo Teräs1-0/+6
ref #574
2012-02-28solver: allow multiple packages with same virtual providesTimo Teräs2-5/+5

ref #574
2012-02-24solver: unallowed pinning is worse than changing installed packageTimo Teräs1-0/+10
2012-02-24test: clean up solver.shTimo Teräs1-5/+9
* take list of tests to run (and default to all) * merge the awk invocation to a function
2012-02-24solver: non preferred actions are worse then non preferred pinningTimo Teräs3-0/+39
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.
2012-02-24pkg, db: use 's' for source repository tags instead of 'p'Timo Teräs1-2/+2
Will use 'p' for provides.
2012-02-24test: improve pinning testsTimo Teräs9-4/+77
2012-02-23test: rewrite the testing framework to use the real appletsTimo Teräs52-115/+208
also merge the expected output to the *.test files.
2012-01-20solver: fix regression from "calculate branch minimum penalty early"Timo Teräs1-2/+1
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.
2012-01-17solver: calculate branch minimum penalty earlyTimo Teräs1-1/+2
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.
