Eelco Dolstra e52ae1c0ff * Use SHA-256 for nix-push. 2005-03-15 11:12:48 +00:00
Eelco Dolstra bd333b939c * Prefix hash algorithm in patch generator too. 2005-03-14 16:46:19 +00:00
Eelco Dolstra db322a47ff * Use a weighted use heuristic to disambiguate between multiple
occurances of a component.  If the shortest path distance between a
  component P and Q in the referers graph is D, then the contribution
  of Q to the use of P is 1 / R^D, where R >= 1, typically 2.  This
  expresses that distant indirect uses are less important than nearby
  uses.

  For instance, this can disambiguate between the bootstrap GCC in
  Nixpkgs and the GCC of the final stdenv (the former has more uses,
  but they are further away),  and between the GCC of the final stdenv
  and the GCC+G77 build (the latter has very few uses).

Eelco Dolstra 2c4302dd7a * Added a disambiguation heuristic: if two components have the same
name but differ to much in sice (by more than a factor of 3), then
  never generate a patch.

Eelco Dolstra 3259ae5811 * Properly specify the hash algorithm in the manifests, and read it
too.
* Change the default hash for nix-prefetch-url back to md5, since
  that's what we use in Nixpkgs (for now; a birthday attack is rather
  unlikely there).
