2006-12-03	* Use a Unix domain socket instead of pipes.	Eelco Dolstra	2	-15/+18

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

2006-12-03	* Pid::kill() should be interruptable.	Eelco Dolstra	1	-1/+3

2006-12-03	* Some hackery to propagate the worker's stderr and exceptions to the	Eelco Dolstra	7	-104/+206
	client.
2006-12-03	* Run the worker in a separate session to prevent terminal signals	Eelco Dolstra	1	-0/+6
	from interfering.
2006-12-02	* Move addTempRoot() to the store API, and add another function	Eelco Dolstra	11	-17/+81
	syncWithGC() to allow clients to register GC roots without needing write access to the global roots directory or the GC lock.
2006-12-02	* Doh.	Eelco Dolstra	1	-1/+1

2006-12-02	* Remove most of the old setuid code.	Eelco Dolstra	3	-138/+57
	* Much simpler setuid code for the worker in slave mode.
2006-12-02	* Remove SwitchToOriginalUser, we're not going to need it anymore.	Eelco Dolstra	8	-63/+4

2006-12-02	* Remove queryPathHash().	Eelco Dolstra	4	-2/+32
	* Help for nix-worker.
2006-12-01	* Replace read-only calls to addTextToStore.	Eelco Dolstra	2	-3/+9

2006-12-01	* Merge addToStore and addToStoreFixed.	Eelco Dolstra	11	-96/+40
	* addToStore now adds unconditionally, it doesn't use readOnlyMode. Read-only operation is up to the caller (who can call computeStorePathForPath).
2006-12-01	* Right name.	Eelco Dolstra	1	-2/+2

2006-12-01	* More operations.	Eelco Dolstra	5	-33/+116
	* 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	12	-46/+138
	* Added new operation hasSubstitutes(), which is more efficient than querySubstitutes().size() > 0.
2006-11-30	* Doh.	Eelco Dolstra	1	-1/+1

2006-11-30	* More operations.	Eelco Dolstra	3	-9/+50

2006-11-30	* First remote operation: isValidPath().	Eelco Dolstra	4	-7/+63

2006-11-30	* When NIX_REMOTE is set to "slave", fork off nix-worker in slave	Eelco Dolstra	5	-24/+87
	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	* Skeleton of the privileged worker program.	Eelco Dolstra	11	-126/+254
	* Some refactoring: put the NAR archive integer/string serialisation code in a separate file so it can be reused by the worker protocol implementation.
2006-11-30	* Oops.	Eelco Dolstra	2	-0/+135

2006-11-30	* Skeleton of remote store implementation.	Eelco Dolstra	4	-6/+14

2006-11-30	* Put building in the store API.	Eelco Dolstra	11	-48/+31

2006-11-30	* Refactoring. There is now an abstract interface class StoreAPI	Eelco Dolstra	17	-338/+458
	containing functions that operate on the Nix store. One implementation is LocalStore, which operates on the Nix store directly. The next step, to enable secure multi-user Nix, is to create a different implementation RemoteStore that talks to a privileged daemon process that uses LocalStore to perform the actual operations.
2006-11-29	* Don't spam.	Eelco Dolstra	1	-0/+2

2006-11-29	* Example script to set permissions for setuid operation.	Roy van den Broek	1	-1/+1

2006-11-29	* Remove --enable-setuid, --with-nix-user and --with-nix-group.	Eelco Dolstra	2	-36/+46
	Rather, setuid support is now always compiled in (at least on platforms that have the setresuid system call, e.g., Linux and FreeBSD), but it must enabled by chowning/chmodding the Nix binaries.
2006-11-24	* Doh! Path sizes need to be computed recursively of course.	Eelco Dolstra	3	-6/+28
	(NIX-70)
2006-11-24	* Dead files.	Eelco Dolstra	2	-12/+0

2006-11-18	* Turn off synchronisation between C and C++ I/O functions. This	Eelco Dolstra	2	-1/+3
	gives a huge speedup in operations that read or write from standard input/output. (So libstdc++'s I/O isn't that bad, you just have to call std::ios::sync_with_stdio(false).) For instance, `nix-store --register-substitutes' went from 1.4 seconds to 0.1 seconds on a certain input. Another victory for Valgrind.
2006-11-13	* Remove the undocumented `noscan' feature. It's no longer necessary	Eelco Dolstra	1	-15/+12
	now that reference scanning is sufficiently streamy.
2006-11-13	* Magic attribute `exportReferencesGraph' that allows the references	Eelco Dolstra	2	-20/+60
	graph to be passed to a builder. This attribute should be a list of pairs [name1 path1 name2 path2 ...]. The references graph of each `pathN' will be stored in a text file `nameN' in the temporary build directory. The text files have the format used by `nix-store --register-validity'. However, the deriver fields are left empty. `exportReferencesGraph' is useful for builders that want to do something with the closure of a store path. Examples: the builders that make initrds and ISO images for NixOS. `exportReferencesGraph' is entirely pure. It's necessary because otherwise the only way for a builder to get this information would be to call `nix-store' directly, which is not allowed (though unfortunately possible).
2006-11-13	* Option `--reregister' in `nix-store --register-validity'. We need	Eelco Dolstra	1	-8/+18
	this in the NixOS installer (or in the buildfarm) to ensure that the cryptographic hash of the path contents still matches the actual contents.
2006-11-03	* Fix importing of derivation outputs.	Eelco Dolstra	1	-2/+9

2006-10-30	* readFile: don't overflow the stack on large files.	Eelco Dolstra	1	-1/+15

2006-10-28	* `nix-store --read-log / -l PATH' shows the build log of PATH, if	Eelco Dolstra	4	-4/+43
	available. For instance, $ nix-store -l $(which svn) \| less lets you read the build log of the Subversion instance in your profile. * `nix-store -qb': if applied to a non-derivation, take the deriver.
2006-10-23	* Some better error messages.	Eelco Dolstra	2	-5/+12

2006-10-19	* Better message.	Eelco Dolstra	1	-1/+1

2006-10-19	* toFile: maintain the references.	Eelco Dolstra	1	-10/+4

2006-10-19	* Special derivation attribute `allowedReferences' that causes Nix to	Eelco Dolstra	1	-0/+31
	check that the references of the output of a derivation are in the specified set. For instance, allowedReferences = []; specifies that the output cannot have any references. (This is useful, for instance, for the generation of bootstrap binaries for stdenv-linux, which must not have any references for purity). It could also be used to guard against undesired runtime dependencies, e.g., {gcc, dynlib}: derivation { ... allowedReferences = [dynlib]; } says that the output can refer to the path of `dynlib' but not `gcc'. A `forbiddedReferences' attribute would be more useful for this, though.
2006-10-17	* Backwards compatibility hack for user environments made by Nix <= 0.10.	Eelco Dolstra	1	-0/+7

2006-10-17	* Backwards compatibility with old user environment manifests.	Eelco Dolstra	2	-4/+8

2006-10-17	* Print out the offending path.	Eelco Dolstra	1	-2/+3

2006-10-17	* An awful backwards compatibility hack.	Eelco Dolstra	1	-0/+24

2006-10-17	* baseNameOf: paths don't have to be absolute.	Eelco Dolstra	1	-1/+1

2006-10-17	* Maintain the references for the user environment properly.	Eelco Dolstra	1	-1/+1

2006-10-17	* toPath: should be the identity on paths.	Eelco Dolstra	1	-3/+1

2006-10-17	* dirOf: return a path if the argument is a path.	Eelco Dolstra	1	-2/+6

2006-10-17	* toString: don't copy paths. So toString can be used to pass	Eelco Dolstra	1	-3/+4
	non-store paths to a builder.
2006-10-17	* Do the path check on the normal form.	Eelco Dolstra	1	-2/+5
