Prior to this change, we had a bunch of ad-hoc string manipulation code
scattered around. This made it hard to figure out what data model for
string contexts is.
Now, we still store string contexts most of the time as encoded strings
--- I was wary of the performance implications of changing that --- but
whenever we parse them we do so only through the
`NixStringContextElem::parse` method, which handles all cases. This
creates a data type that is very similar to `DerivedPath` but:
- Represents the funky `=<drvpath>` case as properly distinct from the
others.
- Only encodes a single output, no wildcards and no set, for the
"built" case.
(I would like to deprecate `=<path>`, after which we are in spitting
distance of `DerivedPath` and could maybe get away with fewer types, but
that is another topic for another day.)

- Add a comment
- Put `OutputsSpec` in a different header (First part of #6815)
- Make a few stray uses of it in new code use `DerivedPath` instead.

runCommand now uses stdenvNoCC by default, so that needs to be
included instead of the regular stdenv.

Don't check NixOS modules
|
|
NixOS modules can be paths. Rather than dig further down into the layer
violation, don't check anything specific to NixOS modules.

this makes the table less unwieldy, and leaves enough space for

add notes on semantics where appropriate
|
|
this form is much easier to maintain (also with minimal diffs), and
allows for more details on each operator.
this change a purely mechanical transformation, without changing any contents.
|
|
this is for a simpler transformation into a series of subsections

macOS doesn't have user namespacing, so the gid of the builder needs
to be nixbld. The logic got "has sandboxing enabled" confused with
"has user namespaces".
Fixes #7529.

This basically reverts 6e5165b77370c76bfa39d4b55e9f83673f3bd466.
It fixes errors like
sandbox-exec: <internal init prelude>:292:47: unable to open sandbox-minimal.sb: not found
when trying to run a development Nix installed in a user's home
directory.
Also, we're trying to minimize the number of installed files
to make it possible to deploy Nix as a single statically-linked
binary.

The `fish_add_path` function is only available for fish 3.2.0 or newer,
and not on older versions.
This commit adds an alternative way to update the PATH when
`fish_add_path` does not exist.

Previously addTempRoot() acquired the LocalStore state lock and waited
for the garbage collector to reply. If the garbage collector is in the
same process (as it the case with auto-GC), this would deadlock as
soon as the garbage collector thread needs the LocalStore state lock.
So now addTempRoot() uses separate Syncs for the state that it
needs. As long at the auto-GC thread doesn't call addTempRoot() (which
it shouldn't), it shouldn't deadlock.
Fixes #3224.
|
|
This also moves the file handle into its own Sync object so we're not
holding the _state while acquiring the file lock. There was no real
deadlock risk here since locking a newly created file cannot block,
but it's still a bit nicer.

This has the same goal as b13fd4c58e81b2b2b0d72caa5ce80de861622610,but
achieves it in a different way in order to not break
`nix why-depends --derivation`.
|
|
- Test with `--derivation`
- Actually test with ca-derivations (was suuposedly done, but not
activated because of a missing line in `local.mk`)

This reverts commit b13fd4c58e81b2b2b0d72caa5ce80de861622610.
