Valentin Gagarin e07448ba6b convert table to subsections
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.

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
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.

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.

Release shared lock before acquiring exclusive lock
In principle, this should avoid deadlocks where two instances of Nix are
holding a shared lock on big-lock and are both waiting to get an
exclusive lock.

However, it seems like `flock(2)` is supposed to do this automatically,
so it's not clear whether this is actually where the problem comes from.
