d0f5719c2a Add "nix copy-sigs" command
This imports signatures from one store into another. E.g.

  $ nix copy-sigs -r /run/current-system -s https://cache.nixos.org/
  imported 595 signatures

9cee600c88 LocalStore: Keep track of ultimately trusted paths
These are content-addressed paths or outputs of locally performed
builds. They are trusted even if they don't have signatures, so "nix
verify-paths" won't complain about them.

bcc9943cee importPaths(): Optionally add NARs to binary cache accessor
This enables an optimisation in hydra-queue-runner, preventing a
download of a NAR it just uploaded to the cache when reading files
like hydra-build-products.

c10c61449f Eliminate the "store" global variable
Also, move a few free-standing functions into StoreAPI and Derivation.

Also, introduce a non-nullable smart pointer, ref<T>, which is just a
wrapper around std::shared_ptr ensuring that the pointer is never
null. (For reference-counted values, this is better than passing a
"T&", because the latter doesn't maintain the refcount. Usually, the
caller will have a shared_ptr keeping the value alive, but that's not
always the case, e.g., when passing a reference to a std::thread via
std::bind.)

7888b2ba15 Define SOL_LOCAL if not defined already (e.g. on FreeBSD).
Some evidence that defining it to be 0 is right:
* OS X headers define it to be 0.
* Other code uses 0 instead of SOL_LOCAL to check for peer credentials
  (e.g. FreeBSD's implementation of getpeereid).

b755752f76 Add a ‘verifyStore’ RPC
Hello!

The patch below adds a ‘verifyStore’ RPC with the same signature as the
current LocalStore::verifyStore method.

Thanks,
Ludo’.

a3e5c99d66 nix-daemon: Call exit(), not _exit()
This was preventing destructors from running. In particular, it was
preventing the deletion of the temproot file for each worker
process. It may also have been responsible for the excessive WAL
growth on Hydra (due to the SQLite database not being closed
properly).

Apparently broken by accident in

49fe9592a4 nix-daemon: Use a thread instead of SIGPOLL to catch client disconnects
The thread calls poll() to wait until a HUP (or other error event)
happens on the client connection. If so, it sends SIGINT to the main
thread, which is then cleaned up normally. This is much nicer than
messing around with SIGPOLL.

049c0eb49c nix-daemon: Add trusted-users and allowed-users options
‘trusted-users’ is a list of users and groups that have elevated
rights, such as the ability to specify binary caches. It defaults to
‘root’. A typical value would be ‘@wheel’ to specify all users in the
wheel group.

‘allowed-users’ is a list of users and groups that are allowed to
connect to the daemon. It defaults to ‘*’. A typical value would be
‘@users’ to specify the ‘users’ group.

51800e06de Allow recovery from isValidPath RPCs with an invalid path
Currently, clients cannot recover from an isValidPath RPC with an
invalid path parameter because the daemon closes the connection when
that happens.

More precisely:

  1. in performOp, wopIsValidPath case, ‘readStorePath’ raises an
     ‘Error’ exception;

  2. that exception is caught by the handler in ‘processConnection’;

  3. the handler determines errorAllowed == false, and thus exits after
     sending the message.

This last part is fixed by calling ‘startWork’ early on, as in the patch
below.

The same reasoning could be applied to all the RPCs that take one or
more store paths as inputs, but isValidPath is, by definition, likely to
be passed invalid paths in the first place, so it’s important for this
one to allow recovery.
