The solver should repsect the (conflicts) field of the (package) stanza.

The solver should say no solution rather than just ignoring the conflict.

When conflicts are obtained from an opam file instead of a dune-project,
|
||
|
|
the behaviour should be the same:
|
||
|
|
|
||
|
|
$ dune build x.opam
|
||
|
|
$ sed -n '/conflicts/,/]/p' x.opam
|
||
|
|
conflicts: [
|
||
|
|
"foo" {< "0.2"}
|
||
|
|
"foo2" {< "0.2"}
|
||
|
|
]
|
||
|
|
|
||
|
|
Even though the conflicts are listed by opam without a `|` to indicate a
|
||
|
|
disjunction, either package is problematic:
|
||
|
|
|
||
|
|
$ mkpkg dune 3.11
|
||
|
|
$ echo '(lang dune 3.11)' | solve_project 2>&1 | sed -E 's/3.[0-9]+/3.XX/'

Adding a new version of `foo` only resolves one conflict:
|
||
|
|
|
||
|
|
$ mkpkg foo 0.2
|
||
|
|
$ echo '(lang dune 3.11)' | solve_project 2>&1 | sed -E 's/3.[0-9]+/3.XX/'

Addition of `foo2` to solve the last remaining conflict:
|

|

$ mkpkg foo2 0.2
|
||
|
|
$ solve_project <<EOF
|
||

|

|

Solution for dune.lock:
|
||
|
|
- bar.0.0.1
|
||
|
|
- bar2.0.0.1
|
||
|
|
- foo.0.2
|
||
|
|
- foo2.0.2
|
||
|
|
|
||
|
|
Same but checking that the latest versions of `foo` and `foo2` are not selected
|
||
|
|
due to the version constraints conflicts:
|
||
|
|
|
||
|
|
$ solve_project << EOF
|
||
|
|
> (lang dune 3.11)
|
||
|
|
> (generate_opam_files true)
|
||
|
|
> (package
|
||
|
|
> (name x)
|
||
|
|
> (allow_empty)
|
||
|
|
> (conflicts (foo (>= 0.2)) (foo2 (>= 0.2)))
|
||
|
|
> (depends bar bar2))
|
||
|
|
> EOF
|
||
|
|
Solution for dune.lock:
|

|
