2004-12-20	* Simplify the substitute mechanism:	Eelco Dolstra	1	-4/+3
	- Drop the store expression. So now a substitute is just a command-line invocation (a program name + arguments). If you register a substitute you are responsible for registering the expression that built it (if any) as a root of the garbage collector. - Drop the substitutes-rev DB table.
2004-08-31	* Main the `substitutes-rev' table again, but now in a way that	Eelco Dolstra	1	-2/+3
	doesn't take \Theta(n^2) space/time complexity.
2004-06-28	* Added a switch `--fallback'. From the manual:	Eelco Dolstra	1	-0/+3
	Whenever Nix attempts to realise a derivation for which a closure is already known, but this closure cannot be realised, fall back on normalising the derivation. The most common scenario in which this is useful is when we have registered substitutes in order to perform binary distribution from, say, a network repository. If the repository is down, the realisation of the derivation will fail. When this option is specified, Nix will build the derivation instead. Thus, binary installation falls back on a source installation. This option is not the default since it is generally not desirable for a transient failure in obtaining the substitutes to lead to a full build from source (with the related consumption of resources).
2004-06-21	* Wrap calls to registerSubstitute() in a single transaction to	Eelco Dolstra	1	-2/+2
	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	-2/+26
	* 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	-0/+3

2003-11-22	* Maintain integrity of the substitute and successor mappings when	Eelco Dolstra	1	-3/+0
	deleting a path in the store. * Allow absolute paths in Nix expressions. * Get nix-prefetch-url to work again. * Various other fixes.
2003-11-18	* libnix -> libstore.	Eelco Dolstra	1	-0/+72
