* Make it easy to run individual tests from the command line. 2006-03-01 13:15:33 +01:00			`source common.sh`

* 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 21:17:54 +02:00			`# Instantiate.`
* Simplification. 2006-03-01 13:51:18 +01:00			`drvPath=$($nixinstantiate substitutes.nix)`
* Propagate the deriver of a path through the substitute mechanism. * Removed some dead code (successor stuff) from nix-push. * Updated terminology in the tests (store expr -> drv path). * Check that the deriver is set properly in the tests. 2005-02-09 13:57:13 +01:00			`echo "derivation is $drvPath"`
