This fixes the issue that `nix-build`, without experimental feature
'nix-command' enabled, recommends the experimental CLI `nix log` to view
build logs. Now it'll recommend the stable `nix-store -l` CLI instead.
Fixes https://github.com/NixOS/nix/issues/8118
in order to make the development process more transparent for everyone,
all pull requests should go through the triage process before getting
merged.
this ensures that all team members are aware of what is going on, and
that rationale for decisions is kept track of in the meeting notes for
posterity. (ideally all that should go into the commit history, but this
is a more invasive process change that needs further deliberation.)
having all team members take at least a brief but conscious look at each
change may also help with keeping our quality standards, as more
reviewers are more likely to remind each other of our shared values.
See the note in the test.
We don't want these flags showing up for commands where they are
irrelevant.
Eventually, this needs a proper fix, but it need not be a blocker for
stabilize: for a quick-n-dirty punt, just put these flags behind the
`nix-command` unstable feature.
This is fine because they are only relevant for commands which we don't
need to stabilize for a while.
`legacyPackages` of nixpkgs trigger eval errors in `hasContent`, causing
the whole `legacyPackages` being skipped. We should treat it as
has-content in that case.
Instead of having a bunch of optional fields, have a few subclasses
which can have mandatory fields.
Additionally, the new `getExtraPathInfo`, and `nixpkgsFlakeRef`, are
moved to `InstallableValue`.
I did these things because https://github.com/NixOS/rfcs/pull/134 ; with
these things moved to `InstallableValue`, the base `Installable` no
longer depends on libexpr! This is a major step towards that.
Also, add a bunch of doc comments for sake of the internal API docs.
Otherwise, a trace consisting of
frame
frame
frame
non-frame
... would reach the non-frame and print the suggestion, even though
it would have ignored the non-frame anyway.
This resulted in a peculariar situation where --show-trace would have
no apparent effect, as the trace was actually already complete.
