2013-01-28solver: remove backjumping by nameTimo Teräs2-29/+3
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 Teräs2-49/+78
Basic per-name per-package specific scoring added.
2013-01-22solver: do not backtrack over "exclude none"Timo Teräs1-1/+8
Otherwise we can return no solution at all instead of partially satisfied solution (and give proper error message).
2013-01-21solver: simplify strength evaluation in constraint handlingTimo Teräs1-20/+8
2013-01-21solver: check if solution is not found at allTimo Teräs1-0/+6
This is an internal error.
2013-01-18solver: fix reset of last_touched to zeroTimo Teräs1-2/+2
2013-01-18solver: some code clean upsTimo Teräs1-5/+5
2013-01-18solver: build fix for debug print on x86_64Natanael Copa1-1/+1
use %zu for size_t
2013-01-18solver: fix name assignment logic to not mess up internal stateTimo Teräs1-11/+10
Should get rid of error messages like: ERROR: Saved_score {4/0/0,74} != score {6/0/0,74}
2012-11-05ver: fix help message of --limitTimo Teräs1-2/+2
2012-11-04solver: fix package prefence calculation a bitTimo Teräs1-1/+3
2012-10-09del: consider also reverse dependencies for provided namesTimo Teräs1-8/+19
So we get better error report if package is not deleted due to reverse dependency.
2012-10-08solver: additional backjumping schemeTimo Teräs2-11/+49
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.
2012-10-08solver: optimize backjumpingTimo Teräs2-8/+9
to be functional when backtracking
2012-10-08solver: properly calculate decision "strength" with providesTimo Teräs1-17/+13
2012-10-05solver: fix back jumping once moreTimo Teräs1-17/+33
2012-10-05solver: record dependency apk_name in apk_decisionTimo Teräs1-51/+19
We can't just use the primary name, as that would mess up backtracking. We need to record the name which caused the name to get considered - that way the right last_touched_decision is used on backtracking.
2012-10-03solver: various fixesTimo Teräs1-14/+58
* push_decision expects to always get the package primary 'name' as apk_name. ASSERT that and fix problem cases. (though - this might need to be reverted, and store the non primary name in apk_decision instead to accomodate for better backtracking optimizations) * fix error reporting of virtual package names * make 'assign_name' errors soft. the incorrect packages just are no longer consider instead of aborting whole calculation. * fix backtracking of virtual packages that are not depended directly
2012-10-03solver: improve assert error messagesNatanael Copa1-2/+3
Print name of package and void double "ERROR"
2012-10-03solver: fix compile with -Werror on 64bitNatanael Copa1-1/+1
2012-09-28info: --provides alias -p is reserved for --root, use -PNatanael Copa1-2/+2
fixes #1396
2012-09-20apk: implement --progress-fd to write progress to a specified fdTimo Teräs4-19/+35
2012-09-04db: remove AT_SYMLINK_NOFOLLOW for directory permissionsTimo Teräs1-2/+2
fchmodat does not support this flag - symlinks do not have permissions. Sysadmin probably does not expect us to not follow symlinks either: if /var -> /mnt/foo/var, we should be making sure the permissions and ownership is correct on the target directory, not on the symlink. Since fchmodat never returned ENOENT with AT_SYMLINK_NOFOLLOW, this also fixes directory re-creation if it does not exist. fixes #1348.
2012-07-16audit: report new directories in recurse mode tooTimo Teräs1-12/+5
Add new 'd' flag for it.
2012-07-16audit: fix protection mask of non-db directoriesTimo Teräs3-26/+27
If a directory has protection mask, but does not exist in db, we do not handle it right unless we calculate the protection mask by hand, or create temporary db dir entry for it. For simplicity create always the db dir entry -- depending on audit type we likely need to create it anyway. This commit also caches the db dir entry in the audit tree context to avoid duplicate lookups. ref #1241.
2012-07-09audit: get right protection mask for base directories in the listsTimo Teräs1-6/+14
Use the paths' protection mask where available instead of the parent paths'. ref #1241
2012-06-06search: improve output format for --rdependsNatanael Copa1-2/+4
- makes -v option useful - makes --origin --quiet --exact useful for piping and scripting - makes the default output more readable
2012-05-07ver: show all packages with -vNatanael Copa1-1/+1
ref #1122
2012-05-07ver: make --quiet output suitable for scripting/pipingNatanael Copa1-0/+4
Do not print version numbers or compare result char when in quiet mode. This makes the output suitable for be used in scripts or pipes. For example: # Upgrade all packages that matches a given regexp apk version --limit '<' --quiet | grep $regexp | apk fix --reinstall # Delete all packages that are removed from repository apk version --limit '?' --quiet | xargs apk del
2012-05-07ver: print '?' when package is not available in any repoNatanael Copa2-1/+3
This makes it possible to differ between downgradable packages (-l '<') and unavailable in repos (-l '?').
2012-05-01audit: apply protected_paths.d masks to individual filesTimo Teräs1-3/+18
2012-05-01db: strip leading and trailing slashes from protected path specTimo Teräs1-0/+6
2012-04-27solver: fix install_if triggers on cyclic and early depsTimo Teräs1-11/+15
2012-04-27solver: fix backtracking with install_if dependenciesTimo Teräs1-17/+20
2012-04-27ver: show all versions if package name specifiedTimo Teräs1-1/+1
fixes #1116
2012-04-27db: fix has_protected_children setup on leaf path entriesTimo Teräs1-1/+1
Fixes --recurse during audit.
2012-04-03pkg: honor --allow-untrusted when installing non-repository packagesTimo Teräs1-13/+21
fixes #1072
2012-03-31solver: fix a type from previous commitTimo Teräs1-1/+1
2012-03-31solver: fix installation of non-repository packagesTimo Teräs1-1/+2
2012-03-30info: fix exit code for -eTimo Teräs1-3/+6
fixes #1069
2012-03-28build: openssl seems to require -ldl for now, so add thatTimo Teräs1-0/+1
2012-03-01solver: properly set allowed flag for installed packagesTimo Teräs1-3/+6
2012-02-29solver: rename some fieldsTimo Teräs1-24/+25
2012-02-29solver: merge apk_name_state to apk_nameTimo Teräs5-236/+220
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.
2012-02-29info: support displaying providesTimo Teräs1-6/+32
2012-02-29solver, test: make conflicts unconditionalTimo Teräs8-50/+65
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.
2012-02-28add: allow specifying repository tag with added virtual packagesTimo Teräs1-2/+12
2012-02-28lua: fix bindings, and build by defaultTimo Teräs2-10/+4
2012-02-28solver: ask confirmation in interactive mode only if there's changesTimo Teräs1-1/+2
2012-02-28solver: do not consider non-allowed packages in main loopTimo Teräs1-43/+32
Instead cache the allowed pinning decision, and use it. Update install decision heuristic to also use this cached information.
