- Don't sign installed packages during finalizer execution
- Enforce solver constraints: build ALO and AMO rules taking into account
that the current package might not be selected at all.
- Force uninstalls on upgrade
- Enable option to tell uninstall to ignore conflict with the analized system state,
as we don't want any conflict with the installed to raise during the upgrade.
In this way we both force uninstalls and we avoid to check with conflicts
against the current system state which is pending to deletion.
This is due to the fact that now the solver enforces the constraints
and explictly denies two packages of the same version installed.
- Adapt test as now we generate more constraints, which makes the solver more
noisy on the package that are explictly selected or not
In this way we don't depend on the package fingerpint characters while generating images, allowing
to support completely semver (e.g. + character is not allowed in docker images tag).
This change is not backward compatible with images currently already built and will invalidate the cache
Having the same var in the and block seems to make gophersat crash. Even if might be unoptimal,
we need this to tighten the conditions between packages.
Switch to gophersat fork until this fix is merged upstream:
https://github.com/crillab/gophersat/pull/17
Add "provides" field in packages (which affect both runtime and buildtime deps).
It replaces all the occurences in the deptree before solving, actually
allowing to swap packages and provide virtuals. Along with a mechanism
for package rename #25.
This happens because we select the best instead of selecting the best match in Package BuildFormula()
- Extend the selection test
- Select from databases when ordering
- Relax assertions search
- Split compile step in test
- Adapt tests
Note: This is temporarly until we treat this case in BuildFormula() inside Package
we need to build the constraints between all the requires when expanding
and then create a new constraint that selects the best match
The version inmemory is optimized, while the boltdb implementation is
not.
It returns a list of the same package but with all the versions present
in the db.
Unmarshalling needs well-defined structs, also swap pointers in few places where needed.
There are few more TODOS pending (like getting UpdatePackage fixed properly)
Fixes races conditions and make the DB Switchable. Also prepare inside
the CompilationSpec the tree of the deps to be built, and parallelize
only the building jobs.
Closes#7
Signed-off-by: Ettore Di Giacinto <mudler@gentoo.org>
Add CompilationSpecs type to handle slices of CompilationSpec, to
perform operation such as Unique() and Remove().
Add also dependencies and the spec associated to the Artifact, to track
how the artifact was generated.
Add revdeps compilation wrapper, and unit tests
Split dependency resolving ( definition <-> db mapping ) into a method of the tree (ResolveDeps),
and do not care of looking up for packages while parsing.
Note: it is slower but it is much accurate and we can
choose what to do with the ones which aren't resolved (and show a helpful message too).
Uninstall can be done in different ways - the most accurate would be to try find a minimum subset of packages that gives conflicts and try to reduce them gradually.
E.g. this could be done with other SAT algorithms. For now we keep things simple and we compute the uninstalls as an indirect of an installation from an empty profile.
Also take care of corner cases where world has no clauses, and fixes a typo in building the world formula
