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.

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 6991e558dd Move macOS sandbox files to sr/libstore/build 2023-01-04 04:50:45 -08:00
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.

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.

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.

rski d034ed1891 src/libstore: Print the reason opening the DB failed 
Without this, the error is lost, and it makes for a hard to debug
situation. Also remove some of the busyness inside the sqlite_open_v2
args.

The errcode returned is not the extended one. The only way to make open
return an extended code, would be to add SQLITE_OPEN_EXRESCODE to the
flags. In the future it might be worth making this change,
which would also simplify the existing SQLiteError code.
