Changelog
apt (2.9.3) unstable; urgency=medium
[ Julian Andres Klode ]
* Initial implementation ("alpha") of the 3.0 solver:
This new solver is available using the --solver 3.0 option.
Highlights:
- Fully backtracking solver, think DPLL without pure literal elimination
- Manually installed packages are not offered up for removal
- New --no-strict-pinning option allows APT to fallback to non-candidate
versions, e.g. apt install --no-strict-pinning foo/experimental installs
foo from experimental and will switch dependencies where needed.
- Autoremove is more aggressive and only keeps the strongest automatically
installed package. For example, gcc-<version> will now be offered for
removal and no longer kept around due libtool Depends: gcc | c-compiler
and gcc-<version> Provides: c-compiler, as `gcc` is already satisfied.
Caveats right now:
- Test suite is not yet passing
- The list of automatically removable packages is not displayed
when automatically installed packages are not removed
- Error information gets lost on backtracking (see Debug::APT::Solver=2)
- Error information is just rendered as A -> B implication graphs,
with some nodes perhaps containing a "not".
- The logic for replacing obsolete manually installed packages with
new replacement packages (think Conflits/Replaces/Provides) is not
yet implemented.
- Conflict-driven clause learning is not implemented, so backtracking
is technically pretty inefficient.
* Solver3 integration fixes:
- test: Ignore progress output in comparing output..
- test-allow-scores-for-all-dependency-types: Adjust for solver3
- EDSP: Add "solver3" alias for apt-internal-solver
* UI work:
- Highlight essential removals with action::remove color
- The text of notices and audits shall not be bold
- Separate columns by 2 spaces in lists (Closes: #1070064)
* Support src:name shortcuts in showsrc, source, build-dep commands
