2014-03-12solver: additional improvements to install_if handlingTimo Teräs1-0/+2
2013-06-20solver: fix pinning+cache to workTimo Teräs1-1/+2
Mistakenly allowed masked out package to be installed if it was in cache.
2013-06-19solver: fix package deletion to consier provides properlyTimo Teräs1-3/+10
2013-06-19solver: properly order deletion of unneeded packagesTimo Teräs1-2/+1
2013-06-19solver: add logic: transitive provides exclusionTimo Teräs1-1/+2
If name N is required, and all providers of A also provide B, it means that only instances of B can be selected that provide N. This is strong help with cases when so:libfoo.so.1 is updated to so:libfoo.so.2 and not everything is recompiled.
2013-06-19upgrade: new option: --latest (-l)Timo Teräs1-0/+1
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.
2013-06-13solver: prune broken world dependencies with --forceTimo Teräs1-0/+1
mostly useful for reboot, when all packages are not available.
2013-06-13solver: corner case fixesTimo Teräs1-0/+2
- try harder to not change anything during self-upgrade - also honor locking to packages that where earlier used in merging common dependencies - clarify upgrade applet help messages
2013-06-13solver: rewrite as deductive solver -- pinning supportTimo Teräs1-2/+4
Fix also pinning test cases to be more sane.
2013-06-13solver: rewrite as deductive solver -- per name flagsTimo Teräs1-2/+4
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 Teräs1-27/+21
Implementing basic dependency handling, install_if and awareness of pinning.
2013-06-12Revert "Revert "solver: increase score fields to 32-bits (from 16-bits)""William Pitcock1-18/+4
This reverts commit a2d873a77c6dd2e7f6219e6941af796e1f904e69.
2013-06-11Revert "solver: increase score fields to 32-bits (from 16-bits)"root1-4/+18
This reverts commit 84bfef1a6b587a7da7d12fb701ab0d1d5d6ce2a9.
2013-04-29solver: increase score fields to 32-bits (from 16-bits)Timo Teräs1-18/+4
We are having so many packages that they might overflow otherwise. "ERROR: Preference overflow" was already reported.
2013-01-28solver: remove backjumping by nameTimo Teräs1-1/+0
It is incorrect optimization causing valid solutions to be skipped. Any performance it might've gained, should be fixed by reintroduction of the minimum penalty logic added in previous commit.
2013-01-28solver: reintroduce minimum penalty logicTimo Teräs1-0/+23
Basic per-name per-package specific scoring added.
2012-10-08solver: additional backjumping schemeTimo Teräs1-0/+1
Enabled when all attempts to satisfy a name failed, we know that we can ignore all decisions until we find a decision affecting the name we wanted to satisfy.
2012-02-29solver: merge apk_name_state to apk_nameTimo Teräs1-0/+45
apk_name_state is now quite small; and we avoid overhead of two pointers (+ malloc overhead) when we just make it part of apk_name. It also fixes some problems (that got introduced) where apk_name_state was not allocated.
