Eelco Dolstra 96c3d8a615 * I love test sets. 2004-12-20 14:38:04 +00:00
Eelco Dolstra 8b9697e575 * An operation `nix-store --clear-substitutes' to remove all
registered substitute mappings.
2004-12-20 14:16:55 +00:00
Eelco Dolstra fa9259f5f5 * Simplify the substitute mechanism:
- Drop the store expression.  So now a substitute is just a
    command-line invocation (a program name + arguments).  If you
    register a substitute you are responsible for registering the
    expression that built it (if any) as a root of the garbage
    collector.
  - Drop the substitutes-rev DB table.

Eelco Dolstra 77970f8daf * Remove `prebuilts.conf' file, it's not like anybody was using it.

2004-12-16 14:31:49 +00:00
Eelco Dolstra e3b051aeeb * Include the size of the bzipped archive (necessary for computing the
cheapest download path), as well as the hash of the contents of the
  path (necessary for checking patch applicability).

Eelco Dolstra 862f4c154e * Patch deployment. `download.pl' (intended to be used in the
substitute mechanism) creates a store path by downloading full NAR
  archives and/or patches specified in the available manifests.

  Any combination of present paths, full downloads, and patches can be
  used to construct the target path.  In particular, patches can be
  chained in sequence; and full NAR archives of the target path can be
  omitted (i.e., patch-only deployment is possible).  A shortest path
  algorithm is used to find the smallest set of files to be downloaded
  (the edge weights are currently file sizes, but one can imagine
  taking the network speed to the various source into account).

  Patches are binary deltas between two store paths.  To be precise,
  they are the output of the `bsdiff' program applied to the NAR
  archives obtained by dumping (`nix-store --dump') the two store
  paths.  The advantage of diff'ing NAR archives (and not, say, doing
  file-by-file diffs) is that file renames/moves are handled
  automatically.  The disadvantage is that we cannot optimise creation
  of unchanged files (by hard-linking).

Eelco Dolstra dca48aed34 * Allow an optional hash to be provided. This prevents redundant
fetches.
2004-12-13 13:35:36 +00:00

Eelco Dolstra 13f77276d1 * utime() follows symlinks, so don't change the mtime if the file is a
symlink.
2004-11-29 19:22:16 +00:00

Eelco Dolstra 4115d8d8ce * Canonicalise metadata of all files in store paths (set the mtime to
0, set the mode to either 444 or 555, set the group to the default).
