2011-12-02	* Move parseHash16or32 into libutil, and use in nix-hash.	Eelco Dolstra	1	-3/+3

2010-11-16	* Store the size of a store path in the database (to be precise, the	Eelco Dolstra	1	-1/+1
	size of the NAR serialisation of the path, i.e., `nix-store --dump PATH'). This is useful for Hydra.
2010-11-16	* Sync with the trunk.	Eelco Dolstra	1	-2/+2

2010-10-04	* Make sure that config.h is included before the system headers,	Eelco Dolstra	1	-2/+2
	because it defines _FILE_OFFSET_BITS. Without this, on OpenSolaris the system headers define it to be 32, and then the 32-bit stat() ends up being called with a 64-bit "struct stat", or vice versa. This also ensures that we get 64-bit file sizes everywhere. * Remove the redundant call to stat() in parseExprFromFile(). The file cannot be a symlink because that's the exit condition of the loop before.
2010-02-24	* `helpText' is now zero-terminated.	Eelco Dolstra	1	-1/+1

2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-3/+6
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-03-01	* Flags `--to-base32' and `--to-base16' to convert between hex and	Eelco Dolstra	1	-2/+19
	base-32 hashes.
2005-08-14	* nix-hash: option `--truncate' to truncate the hash to 160 bits. Hmm,	Eelco Dolstra	1	-0/+3
	kind of ad hoc ;-)
2005-01-17	* Removed the `id' attribute hack.	Eelco Dolstra	1	-7/+10
	* 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	* Shorten SHA-256 hashes used in store path name generation to 160	Eelco Dolstra	1	-2/+2
	bits, then encode them in a radix-32 representation (using digits and letters except e, o, u, and t). This produces store paths like /nix/store/4i0zb0z7f88mwghjirkz702a71dcfivn-aterm-2.3.1. The nice thing about this is that the hash part of the file name is still 32 characters, as before with MD5. (Of course, shortening SHA-256 to 160 bits makes it no better than SHA-160 in theory, but hopefully it's a bit more resistant to attacks; it's certainly a lot slower.)
2005-01-14	* Add SHA-256.	Eelco Dolstra	1	-0/+1
	* Tests for the various hashes.
2005-01-13	* Added SHA-1 support. `nix-hash' now has an option `--type sha1' to	Eelco Dolstra	1	-2/+13
	select SHA-1 hashing.
2003-12-01	* Help text for all (non-script) programs, so no more:	Eelco Dolstra	1	-0/+7
	$ nix-instantiate --help error: unknown flag `--help` Try `nix-instantiate --help' for more information. :-)
2003-10-20	* Refactored the source tree.	Eelco Dolstra	1	-0/+20
