Robert Hensing 34a1e0d29b doc/manual: Introduce @docroot@ as a stable base for includable snippets
This way the links are clearly within the manual (ie not absolute paths),
while allowing snippets to reference the documentation root reliably,
regardless of at which base url they're included.

Robert Hensing be10c09d23 manual: Check links
mdbook-linkcheck is not consistent about its warning setting.
It disables some warnings, but not the warnings about lack of
fragment checking support; hence the extra filtering.

John Ericson 5576d5e987 Parse string context elements properly
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.)

John Ericson da64f026dd Make clear that StorePathWithOutputs is a deprecated type
- 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.

Eelco Dolstra 4e84b532ed On macOS with auto-uid-allocation and sandboxing, use the correct gid
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.

Eelco Dolstra 609a7dc059 Include macOS sandbox files in the Nix binary
This basically reverts 6e5165b773.
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.

Alexandre Thomas 49e058f1cf Fix Nix installation on older versions of fish

and not on older versions.

`fish_add_path` does not exist.

unsafeDiscardReferences
Adds a new boolean structured attribute
`outputChecks.<output>.unsafeDiscardReferences` which disables scanning
an output for runtime references.

    __structuredAttrs = true;
    outputChecks.out.unsafeDiscardReferences = true;

This is useful when creating filesystem images containing their own embedded Nix
store: they are self-contained blobs of data with no runtime dependencies.

Setting this attribute requires the experimental feature
`discard-references` to be enabled.

Eelco Dolstra 28d5b5cd45 Fix deadlock between auto-GC and addTempRoot()
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.
2023-01-03 15:20:21 +01:00
Eelco Dolstra 224b56f10e Move creation of the temp roots file into its own function
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.
