2006-12-05	* The determination of the root set should be made by the privileged	Eelco Dolstra	1	-4/+36
	process, so forward the operation. * Spam the user about GC misconfigurations (NIX-71). * findRoots: skip all roots that are unreadable - the warnings with which we spam the user should be enough.
2006-12-04	* Add indirect root registration to the protocol so that unprivileged	Eelco Dolstra	1	-0/+9
	processes can register indirect roots. Of course, there is still the problem that the garbage collector can only read the targets of the indirect roots when it's running as root...
2006-12-04	* Don't redirect stderr.	Eelco Dolstra	1	-6/+0

2006-12-04	* Handle exceptions and stderr for all protocol functions.	Eelco Dolstra	1	-0/+10
	* SIGIO -> SIGPOLL (POSIX calls it that). * Use sigaction instead of signal to register the SIGPOLL handler. Sigaction is better defined, and a handler registered with signal appears not to interrupt fcntl(..., F_SETLKW, ...), which is bad.
2006-12-04	* Daemon mode (`nix-worker --daemon'). Clients connect to the server	Eelco Dolstra	1	-1/+2
	via the Unix domain socket in /nix/var/nix/daemon.socket. The server forks a worker process per connection. * readString(): use the heap, not the stack. * Some protocol fixes.
2006-12-04	* When NIX_REMOTE=daemon, connect to /nix/var/nix/daemon.socket	Eelco Dolstra	1	-7/+29
	instead of forking a worker.
2006-12-04	* Refactoring.	Eelco Dolstra	1	-13/+29

2006-12-04	* Pass the verbosity level to the worker.	Eelco Dolstra	1	-2/+8

2006-12-04	* Install the worker in bindir, not libexecdir.	Eelco Dolstra	1	-1/+4
	* Allow the worker path to be overriden through the NIX_WORKER environment variable.
2006-12-03	* Don't run setuid root when build-users is empty.	Eelco Dolstra	1	-0/+1
	* Send startup errors to the client.
2006-12-03	* Use a Unix domain socket instead of pipes.	Eelco Dolstra	1	-13/+17

2006-12-03	* Better error message if the worker doesn't start.	Eelco Dolstra	1	-4/+8

2006-12-03	* Some hackery to propagate the worker's stderr and exceptions to the	Eelco Dolstra	1	-5/+34
	client.
2006-12-02	* Move addTempRoot() to the store API, and add another function	Eelco Dolstra	1	-0/+15
	syncWithGC() to allow clients to register GC roots without needing write access to the global roots directory or the GC lock.
2006-12-02	* Remove queryPathHash().	Eelco Dolstra	1	-1/+4
	* Help for nix-worker.
2006-12-01	* Merge addToStore and addToStoreFixed.	Eelco Dolstra	1	-28/+4
	* addToStore now adds unconditionally, it doesn't use readOnlyMode. Read-only operation is up to the caller (who can call computeStorePathForPath).
2006-12-01	* More operations.	Eelco Dolstra	1	-1/+24
	* addToStore() and friends: don't do a round-trip to the worker if we're only interested in the path (i.e., in read-only mode).
2006-11-30	* More remote operations.	Eelco Dolstra	1	-18/+32
	* Added new operation hasSubstitutes(), which is more efficient than querySubstitutes().size() > 0.
2006-11-30	* More operations.	Eelco Dolstra	1	-5/+18

2006-11-30	* First remote operation: isValidPath().	Eelco Dolstra	1	-4/+14

2006-11-30	* When NIX_REMOTE is set to "slave", fork off nix-worker in slave	Eelco Dolstra	1	-1/+53
	mode. Presumably nix-worker would be setuid to the Nix store user. The worker performs all operations on the Nix store and database, so the caller can be completely unprivileged. This is already much more secure than the old setuid scheme, since the worker doesn't need to do Nix expression evaluation and so on. Most importantly, this means that it doesn't need to access any user files, with all resulting security risks; it only performs pure store operations. Once this works, it is easy to move to a daemon model that forks off a worker for connections established through a Unix domain socket. That would be even more secure.
2006-11-30	* Oops.	Eelco Dolstra	1	-0/+82
