Eelco Dolstra 7dd342e482 * Doh. 2006-09-19 16:40:22 +00:00
Eelco Dolstra ee6cf99660 * Doh! Of course we have to take execute permission into account. 
* Restore the mtime on modified directories.

Eelco Dolstra 6dbed1bf38 * `optimise-store.pl' reduces disk space consumption by hard-linking 
all identitical files in the Nix store to each other.  (Previously
  it only computed the size that would be saved by doing so.)

Eelco Dolstra 9488ae7357 * `show-duplication.pl', a small utility that shows the amount of 
package duplication present in (e.g.) a profile.  It shows the
  number of instances of each package in a closure, along with the
  size in bytes of each instance as well as the "waste" (the
  difference between the sum of the sizes of all instances and the
  average size).

  $ ./show-duplication.pl /nix/var/nix/profiles/default
  gcc 11
    3.3.6 19293318
    3.4.4 21425257
    ...
    average 14942970, waste 149429707
  coreutils 6
  ...
  average package duplication 1.87628865979381, total size 3486330471, total waste 1335324237, 38.3017114443825% wasted

  This utility is useful for measuring the cost in terms of disk space
  of the Nix approach.

Eelco Dolstra 6af4a5a71f * Prototype store optimiser. It searched the Nix store for identical 
files and hard-links them to each other to save disk space.

  Currently it doesn't actually do the hard-linking, it just reports
  the amount of space saved if it did.
