Eelco Dolstra	daf0a923c7	* Wrap calls to registerSubstitute() in a single transaction to ... 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.	2004-06-21 07:38:17 +00:00
Eelco Dolstra	112ee89501	* Re-enable support for substitutes in the normaliser. ... * 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.	2004-06-20 19:17:54 +00:00
Eelco Dolstra	a4d2b22c8c	* Be stricter in verifying store paths.	2004-04-14 08:08:55 +00:00
Eelco Dolstra	ab0bc4999a	* Maintain integrity of the substitute and successor mappings when ... 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 18:45:56 +00:00
Eelco Dolstra	9f0f020929	* libnix -> libstore.	2003-11-18 10:55:27 +00:00
