2004-06-20 * Re-enable support for substitutes in the normaliser.Eelco Dolstra1-23/+31
* 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.
2004-02-14 * The environment variable NIX_ROOT can now be set to execute Nix in aEelco Dolstra1-1/+30
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.
2004-01-09 * Option `--force-realise' in `nix-store --query'.Eelco Dolstra1-5/+12
2003-12-01 * Help text for all (non-script) programs, so no more:Eelco Dolstra1-9/+1
$ nix-instantiate --help error: unknown flag `--help` Try `nix-instantiate --help' for more information. :-)
2003-11-19 * nix-env: a tool to manage user environments.Eelco Dolstra1-3/+2
* Replace all directory reading code by a generic readDirectory() function.
2003-11-18 * "Fix expression" -> "Nix expression".Eelco Dolstra1-0/+303
* More refactoring.
