2012-02-24solver, dot: elementary provides fixesTimo Teräs4-57/+108
implementation is still not near finished, but now at least it can handle it to a minimum degree. many cases are not done right yet, though. ref #574.
2012-02-24all: introduce apk_provides and use it in apk_nameTimo Teräs13-210/+309
in preparation for provides support. implements also some dependency satisfaction helper routines. ref #574.
2012-02-24solver: unallowed pinning is worse than changing installed packageTimo Teräs2-10/+17
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 Teräs4-6/+55
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: add field for provides as 'p'Timo Teräs2-2/+8
ref #574
2012-02-24pkg, db: use 's' for source repository tags instead of 'p'Timo Teräs3-4/+5
Will use 'p' for provides.
2012-02-24verify: report only bad packages with -qTimo Teräs1-2/+7
fixes #1010
2012-02-24apk: do not enable automatically interactive mode with --simulateTimo Teräs1-5/+13
2012-02-24test: improve pinning testsTimo Teräs11-10/+89
2012-02-23solver: fix output of broken dependenciesTimo Teräs1-1/+1
2012-02-23test: rewrite the testing framework to use the real appletsTimo Teräs57-346/+279
also merge the expected output to the *.test files.
2012-02-23pkg: fix writing of versioned conflictsTimo Teräs1-1/+1
2012-02-23db: keep architecture in $ROOT/etc/apk/archTimo Teräs3-8/+54
This we use proper arch in case modifying chroot installation.
2012-02-23solver: report size difference in kibi- or mebibytesTimo Teräs1-5/+11
2012-02-23apk: /etc/apk/interactive enables interactive mode for tty sessionsTimo Teräs1-1/+4
In case someone prefers extra quesions while running apk in a terminal. The file is always from the real root; not from --root so that we will not accidentally enable interactive mode when in initramfs bootstrap.
2012-02-23audit, db: add etc/apk/protected_files.d and new audit featuresTimo Teräs5-187/+322
fixes #607. audit is now mostly rewritten for the new functionality. And has new features like --check-permissions, --recursive and --packages. $ROOT/etc/apk/protected_files.d/*.list can now contain additional protected paths, one path per line: +etc @etc/init.d -tmp + will include the directory as protected configuration directory. @ considers the directory protected, but will backup only symlinks. - removes any protection lbu should be modified to put include and exclude paths in etc/apk/protected_files.d/lbu.list. Additionally, some packages might provide their own listings. E.g. ssh might want to provide ssh.list with something like: +root/.ssh +home/*/.ssh
2012-02-22db: fix repositories.d to be loaded only without --repositories-fileTimo Teräs1-3/+7
2012-02-22db, io: load repositories also from etc/apk/repositories.d/*.listTimo Teräs5-20/+39
Load additional repositories from $ROOT/etc/apk/repositories.d/*.list unless --repositories-file is given as parameter.
2012-02-22solver: lock early names that have only single option leftTimo Teräs1-3/+13
care is needed to get the score right.
2012-02-22solver: lazily update name state in main loopTimo Teräs1-171/+125
2012-02-22solver: handle fix/reinstall betterTimo Teräs1-30/+36
In case someone did "fix --force" for package for which we have no APK available, we would uninstall the package instead of silently ignoring the request. This could mean worse things. So now we just consider unavailable packages a bad deal for reinstall requests. And will downgrade if necessary. But if we really don't have any APK available, we just skip the request but report it.
2012-02-22db: merge identical repositoriesTimo Teräs1-5/+17
Just in case same repository is mentioned with different tags.
2012-02-22solver: transitive dependency requiringTimo Teräs1-12/+41
If n+1 packages depend A, and A depend on B. Add n+1 dependencies to B. Otherwise if someone conflicts B, B might be left out. Leaving package unassigned is no longer a non-preferred action, this fixes the final test case that was failing. And with --force we might even install that scenario. Add also some debug checks.
2012-02-22solver: remove dependency merging; it's not worth itTimo Teräs1-77/+4
callgrind says it's more overhead than improvement. back jumping effectively prunes all bad trees. but can be added later if it becomes needed; due to e.g. provides support.
2012-02-22db, solver, io: scan cache items at startupTimo Teräs8-154/+207
It is faster to just scan the cache directory for existing packages at startup than trying to faccessat() them on demand. It also makes quite a few parts of the code more readable and simpler.
2012-02-21solver: make apk_score a 64-bit int for speedTimo Teräs1-9/+49
2012-02-21solver: remove unneeded flagTimo Teräs1-4/+1
2012-02-21solver: implement backwards jumping and various other optimizationsTimo Teräs3-151/+227
2012-02-20solver: rewrite backtracking and scoring systemTimo Teräs2-406/+695
* properly do absolute scoring now, the previous scoring where preference could get reduced could have caused incorrect early pruning of search tree * backtracking is now separated from package state, and first branching point is the decision if a name is left unassigned or if something _has_ to be assigned. this allows multiple future search tree optimizations like handling of common dependencies early. * merge common dependency names early to provide deeper forward checking.
2012-02-17apk: fix some unharmful leaks reported by valgrindTimo Teräs3-9/+19
2012-02-17solver: get rid of saved score in backtrackingTimo Teräs1-41/+57
also, discover late if package is needed or not.
2012-02-16solver: convert some package state flags to bitfieldsTimo Teräs1-11/+13
2012-02-16solver: name's unlocked chosen is always next package getting lockedTimo Teräs1-35/+28
Instead of "skipping" certain packages, we include them as-if required, and at expansion time we decide if they actually need to be considered for installation. This cleans up the expansion main loop a little bit and makes the code work together better.
2012-02-16solver: rework internals a bitTimo Teräs1-138/+190
* cleaned up little bit on the internal state machine * the decision applying mechanism now aborts early to avoid work if we are approaching bad solution candidate * package availability checking is now done on-demand; which could still be improved
2012-02-16solver: fix allowed pinning calculationTimo Teräs1-2/+2
2012-02-16solver: record repository tag, and flags in solutionTimo Teräs5-68/+113
name state could get overwritten later, so we can't use that when generating the changeset.
2012-02-16solver: remove an unneeded name state variableTimo Teräs1-5/+0
2012-02-15ver: handle pinned packages betterTimo Teräs1-7/+36
2012-02-15solver, db: repository pinning improvementsTimo Teräs7-65/+91
* solver internally calculates now using tags; not repository masks * installeddb now contains the tag name where the package came from -> we can now handle upgrades properly * the pinning is still a preference, and not strictly enforced; versioned dependencies may overrule preference
2012-02-14ver: by default show only upgradeable packagesTimo Teräs1-0/+6
2012-02-14audit: check dirent mode, uid and gid if requestedTimo Teräs1-32/+71

2012-02-10db: allow directory to have sticky bit, and suid/sgid bits setTimo Teräs1-1/+1
2012-02-10db, fix: more secure way to choose effective directory permissionsTimo Teräs3-11/+32
And implement --directory-permissions for fix-applet to reset all directory uid, gid and modes.
