2007-09-18	* Pass various options to the worker so that flags like -K or -j work	Eelco Dolstra	1	-2/+21
	in multi-user Nix (NIX-72). * Client/worker: exchange a protocol version number for future compatibility.
2007-08-12	* Get rid of the substitutes database table (NIX-47). Instead, if we	Eelco Dolstra	1	-6/+6
	need any info on substitutable paths, we just call the substituters (such as download-using-manifests.pl) directly. This means that it's no longer necessary for nix-pull to register substitutes or for nix-channel to clear them, which makes those operations much faster (NIX-95). Also, we don't have to worry about keeping nix-pull manifests (in /nix/var/nix/manifests) and the database in sync with each other. The downside is that there is some overhead in calling an external program to get the substitutes info. For instance, "nix-env -qas" takes a bit longer. Abolishing the substitutes table also makes the logic in local-store.cc simpler, as we don't need to store info for invalid paths. On the downside, you cannot do things like "nix-store -qR" on a substitutable but invalid path (but nobody did that anyway). * Never catch interrupts (the Interrupted exception).
2007-06-12	* Support queryDeriver() in multi-user installations.	Eelco Dolstra	1	-6/+12

2007-05-01	* Set a terminate() handler to ensure that we leave the BDB	Eelco Dolstra	1	-2/+2
	environment cleanly even when an exception is thrown from a destructor. We still crash, but we don't take all other Nix processes with us.
2007-02-21	* `nix-store --import' now also works in remote mode. The worker	Eelco Dolstra	1	-6/+24
	always requires a signature on the archive. This is to ensure that unprivileged users cannot add Trojan horses to the Nix store.
2007-02-21	* Support exportPath() in remote mode.	Eelco Dolstra	1	-4/+12

2007-02-21	* `nix-store --import': import an archive created by `nix-store	Eelco Dolstra	1	-0/+6
	--export' into the Nix store, and optionally check the cryptographic signatures against /nix/etc/nix/signing-key.pub. (TODO: verify against a set of public keys.)
2007-02-20	* Start of `nix-store --export' operation for serialising a store	Eelco Dolstra	1	-0/+7
	path. This is like `nix-store --dump', only it also dumps the meta-information of the store path (references, deriver). Will add a `--sign' flag later to add a cryptographic signature, which we will use for exchanging store paths between build farm machines in a secure manner.
2006-12-12	* New primop builtins.filterSource, which can be used to filter files	Eelco Dolstra	1	-2/+2
	from a source directory. All files for which a predicate function returns true are copied to the store. Typical example is to leave out the .svn directory: stdenv.mkDerivation { ... src = builtins.filterSource (path: baseNameOf (toString path) != ".svn") ./source-dir; # as opposed to # src = ./source-dir; } This is important because the .svn directory influences the hash in a rather unpredictable and variable way.
2006-12-05	* Allow unprivileged users to run the garbage collector and to do	Eelco Dolstra	1	-0/+21
	`nix-store --delete'. But unprivileged users are not allowed to ignore liveness. * `nix-store --delete --ignore-liveness': ignore the runtime roots as well.
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
