the only bit of information needed in solver commit is the "hard"
topology sorting information for trigger ordering. fixes a bug in
"apk del" which uses the state pointers to do intermediate
calculations between solution solving and commit.
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.
* each package name has two sorting positions, one which causes
install_if triggers to be run, and other for bulk dependencies
* fix also inverted ordering of package installations
* the solver no longer does look-ahead locking of names
(could be possibly optimized later); instead names are now
always ordered strictly to properly detect the package names
which are unsolveable
* basic error tests added, so we can see the most likely problem
in dependencies easily
* basic code for a backtracking, forward checking dependency satisfier
* works better when there are tricky dependencies to solve
(when can't just upgrade everything to most preferred versions)
* the new code always evaluates all of 'world' constraints
(old code just does incremental updates based on heuristics)
* is probably somewhat slower than old code (probably unnoticeable
difference in most cases)
* makes easier to write support for provides and repository pinning
* test applet and a bunch of test cases added which uses the new code
* from the old feature set install_if is not yet implemented
This applet can be used to generate data for graphviz tools.
Useful to visualize package dependencies, and possible errors
in the repository.
Usage examples:
apk dot gnome-desktop | tred | dot -Tpng gnome-desktop.png
-- to generate simplified dependency chart of gnome-desktop
apk dot --errors | dot -Tpng index-errors.png
-- to generate chart visualizing dependency errors in index
Make indexer keep noise about errors that prevent index generation.
Detect certain errors in the APKs better. And also have the applet
return error in these scenarios.
commit 4e72075fba introduced a bug where package installation might happen
in wrong order (reminder for self to separate the package version deduction
to separate step from installation ordering). this restricts the earlier
commit to not mingle with the install order.
