This requires `--substitute-on-destination` if you want the remote side
to substitute instead of copying if possible.
For completeness sake, document it here.
Also, the stable Nix from nixpkgs is still 2.18, so more folks may
stumble upon this when this is bumped, so I'd expect this to be actually
useful.
Closes#10182
- Align the “frequent” release cycle with the calendar
- The 6-month release cycle is hard to keep track of. A monthly
release will make it much easier to remember the release date.
- Officialise the support for a stable version maintained for as long as NixOS stable
- This is already the case in practice, it just happens that the
“stable” Nixpkgs version is whichever version was deemed
stable-enough at the time of the NixOS release.
Officialise that by cutting a new major release alongside each NixOS one.
Note that this breaks whatever semver compatibility Nix might pretend to
have, but I don't think it makes sense any way.
As discussed in our last meeting, we need a bit more time, but we are
"time boxing" the work left to do to ensure there is not unbounded
delay.
Rather than putting it back underneath `flakes`, though, put it
underneath its own `fetch-tree` experimental feature (which `flakes`
includes/implies). This signals our commitment to the plan to stabilize
it first without waiting to go through the rest of Flakes, and also will
give users a "release candidate" when we get closer to stabilization.
This reverts commit 4112dd1fc9.
Before it returned a list of JSON objects with store object information,
including the path in each object. Now, it maps the paths to JSON
objects with the metadata sans path.
This matches how `nix derivation show` works.
Quite hillariously, none of our existing functional tests caught this
change to `path-info --json` though they did use it. So just new
functional tests need to be added.
This adds publicKeys as an optional fetcher input attribute to flakes
and builtins.fetchGit to provide a nix interface for the json-encoded
`publicKeys` attribute of the git fetcher.

Single quotes are a basic feature of shell syntax that people expect to
work. They are also more convenient for writing literal code expressions
with less escaping.
