2005-01-19	* Change extension `.store' to `.drv'.	Eelco Dolstra	1	-4/+11
	* Re-enable `nix-store --query --requisites'.
2005-01-19	* Started removing closure store expressions, i.e., the explicit	Eelco Dolstra	1	-108/+28
	representation of closures as ATerms in the Nix store. Instead, the file system pointer graph is now stored in the Nix database. This has many advantages: - It greatly simplifies the implementation (we can drop the notion of `successors', and so on). - It makes registering roots for the garbage collector much easier. Instead of specifying the closure expression as a root, you can simply specify the store path that must be retained as a root. This could not be done previously, since there was no way to find the closure store expression containing a given store path. - Better traceability: it is now possible to query what paths are referenced by a path, and what paths refer to a path.
2005-01-17	* Removed the `id' attribute hack.	Eelco Dolstra	1	-5/+32
	* Formalise the notion of fixed-output derivations, i.e., derivations for which a cryptographic hash of the output is known in advance. Changes to such derivations should not propagate upwards through the dependency graph. Previously this was done by specifying the hash component of the output path through the `id' attribute, but this is insecure since you can lie about it (i.e., you can specify any hash and then produce a completely different output). Now the responsibility for checking the output is moved from the builder to Nix itself. A fixed-output derivation can be created by specifying the `outputHash' and `outputHashAlgo' attributes, the latter taking values `md5', `sha1', and `sha256', and the former specifying the actual hash in hexadecimal or in base-32 (auto-detected by looking at the length of the attribute value). MD5 is included for compatibility but should be considered deprecated. * Removed the `drvPath' pseudo-attribute in derivation results. It's no longer necessary. * Cleaned up the support for multiple output paths in derivation store expressions. Each output now has a unique identifier (e.g., `out', `devel', `docs'). Previously there was no way to tell output paths apart at the store expression level. * `nix-hash' now has a flag `--base32' to specify that the hash should be printed in base-32 notation. * `fetchurl' accepts parameters `sha256' and `sha1' in addition to `md5'. * `nix-prefetch-url' now prints out a SHA-1 hash in base-32. (TODO: a flag to specify the hash.)
2005-01-14	* Start move towards SHA-256 hashes instead of MD5.	Eelco Dolstra	1	-13/+3
	* Start cleaning up unique store path generation (they weren't always unique; in particular the suffix ("-aterm-2.2", "-builder.sh") was not part of the hash, therefore changes to the suffix would cause multiple store objects with the same hash).
2005-01-13	* Added SHA-1 support. `nix-hash' now has an option `--type sha1' to	Eelco Dolstra	1	-1/+1
	select SHA-1 hashing.
2004-11-03	* string2ATerm -> overloaded toATerm.	Eelco Dolstra	1	-7/+7

2004-10-29	* Drop ATmake / ATMatcher also in handling store expressions.	Eelco Dolstra	1	-30/+31

2004-10-25	* Allow certain operations to succeed even if we don't have write	Eelco Dolstra	1	-1/+1
	permission to the Nix store or database. E.g., `nix-env -qa' will work, but `nix-env -qas' won't (the latter needs DB access). The option `--readonly-mode' forces this mode; otherwise, it's only activated when the database cannot be opened.
2004-01-12	* Changed the extension for store expressions from ".nix" to ".store"	Eelco Dolstra	1	-1/+1
	(following the Usenix paper).
2003-11-18	* "Nix expression" -> "store expression".	Eelco Dolstra	1	-0/+197
	* More refactoring.
