The sandbox rule `(allow network* (local ip))` doesn't do what it
implies. Adding this rule permits all network traffic. We should be
matching on (remote ip "localhost:*")` instead.
This seems to have found one actual bug in fs-sink.cc: the symlink case
was falling into the regular file case, which can't possibly be
intentional, right?
Docker uses "latest" as the default label instead of "master".
This change will allow to docker run ghcr.io/nixos/nix without having to
specify the label.
It keeps the :master label on docker hub for back-compat.
When a file conflict arises during a package install a suggestion is
made to remove the old entry. This was previously done using the
installable URLs of the old entry. These URLs are quite verbose and
often do not equal the URL of the existing entry.
This change uses the recently introduced profile entry name for the
suggestion, resulting in a simpler output.
The improvement is easily seen in the change to the functional test.
- `nix store add` supports text hashing
With functional test ensuring it matches `builtins.toFile`.
- Factored-out flags for both commands
- Move all common reusable flags to `libcmd`
- They are not part of the *definition* of the CLI infra, just a usag
of it.
- The `libstore` flag couldn't go in `args.hh` in libutil anyways,
would be awkward for it to live alone
- Shuffle around `Cmd*` hierarchy so flags for deprecated commands don't
end up on the new ones
This PR reduces the creation of short-lived basic_json objects while
parsing flake.lock files. For large flake.lock files (~1.5MB) I was
observing ~60s being spent for trivial nix build operations while
after this change it is now taking ~1.6s.
It's better to just check whether the input has all the attributes
needed to consider itself locked (e.g. whether a Git input has an
'rev' attribute).
Also, the 'locked' field was actually incorrect for Git inputs: it
would be set to true even for dirty worktrees. As a result, we got
away with using fetchTree() internally even though fetchTree()
requires a locked input in pure mode. In particular, this allowed
'--override-input' to work by accident.
The fix is to pass a set of "overrides" to call-flake.nix for all the
unlocked inputs (i.e. the top-level flake and any --override-inputs).
This fixes warnings like
warning: Ignoring setting 'auto-allocate-uids' because experimental feature 'auto-allocate-uids' is not enabled
warning: Ignoring setting 'impure-env' because experimental feature 'configurable-impure-env' is not enabled
when using the daemon and the user didn't actually set those settings.
Note: this also hides those settings from `nix config show`, but that
seems a good thing.
`canonPath` and `absPath` work on native paths, and so should switch
between supporting Unix paths and Windows paths accordingly.
The templating is because `CanonPath`, which shares the implementation,
should always be Unix style. It is the pure "nix-native" path type for
virtual file operations --- it is part of Nix's "business logic", and
should not vary with the host OS accordingly.
