2004-06-21	* Remove obstructing invalid store paths add[Text]ToStore().	Eelco Dolstra	1	-0/+6

2004-06-21	* Wrap calls to registerSubstitute() in a single transaction to	Eelco Dolstra	1	-8/+4
	improve throughput. * Don't build the `substitute-rev' table for now, since it caused Theta(N^2) time and log file consumption when adding N substitutes. Maybe we can do without it.
2004-06-20	* Re-enable support for substitutes in the normaliser.	Eelco Dolstra	1	-58/+107
	* A better substitute mechanism. Instead of generating a store expression for each store path for which we have a substitute, we can have a single store expression that builds a generic program that is invoked to build the desired store path, which is passed as an argument. This means that operations like `nix-pull' only produce O(1) files instead of O(N) files in the store when registering N substitutes. (It consumes O(N) database storage, of course, but that's not a performance problem). * Added a test for the substitute mechanism. * `nix-store --substitute' reads the substitutes from standard input, instead of from the command line. This prevents us from running into the kernel's limit on command line length.
2004-04-14	* Be stricter in verifying store paths.	Eelco Dolstra	1	-4/+5

2004-02-14	* The environment variable NIX_ROOT can now be set to execute Nix in a	Eelco Dolstra	1	-9/+29
	chroot() environment. * A operation `--validpath' to register path validity. Useful for bootstrapping in a pure Nix environment. * Safety checks: ensure that files involved in store operations are in the store.
2004-01-15	* Catch SIGINT to terminate cleanly when the user tries to interrupt	Eelco Dolstra	1	-1/+1
	Nix. This is to prevent Berkeley DB from becoming wedged. Unfortunately it is not possible to throw C++ exceptions from a signal handler. In fact, you can't do much of anything except change variables of type `volatile sig_atomic_t'. So we set an interrupt flag in the signal handler and check it at various strategic locations in the code (by calling checkInterrupt()). Since this is unlikely to cover all cases (e.g., (semi-)infinite loops), sometimes SIGTERM may now be required to kill Nix.
2004-01-13	* Print error messages, not debug messages.	Eelco Dolstra	1	-5/+9

2003-12-22	* GCC 2.95 compatibility.	Eelco Dolstra	1	-0/+1

2003-12-05	* Allow successors that don't exist but have a substitute.	Eelco Dolstra	1	-34/+73
	* Integrity: check in successor / substitute registration whether the target path exists or has a substitute.
2003-11-24	* Bug fix in path invalidation.	Eelco Dolstra	1	-23/+41
	* More consistency checks.
2003-11-22	* Maintain integrity of the substitute and successor mappings when	Eelco Dolstra	1	-37/+54
	deleting a path in the store. * Allow absolute paths in Nix expressions. * Get nix-prefetch-url to work again. * Various other fixes.
2003-11-22	* Fix the garbage collector.	Eelco Dolstra	1	-8/+1

2003-11-18	* libnix -> libstore.	Eelco Dolstra	1	-0/+407
