Eelco Dolstra b88460bcbc * Disregard the Hash field in manifests. 2009-03-19 09:47:34 +00:00
Eelco Dolstra 9441550acb * nix-push / generate-patches: bzip the manifest. 2007-09-04 15:38:09 +00:00
Eelco Dolstra bae75ca5a1 * New kind of manifest object: "localPath", which denotes that a store 
path can be created by copying it from another location in the file
  system.  This is useful in the NixOS installation.
 2007-01-23 16:50:19 +00:00
Eelco Dolstra 36d9258c0d * Successors have been gone for ages. 2007-01-23 16:05:59 +00:00
Eelco Dolstra 5168f9bb00 * Canonicalise manifests a bit by sorting them. 2006-02-24 16:02:36 +00:00
Eelco Dolstra 7272c3f817 * Ignore hash conflicts in gc-releases.pl. 2005-03-18 09:43:25 +00:00
Eelco Dolstra 8eff18cd43 * Set NAR name to content hash; previous nix-push names were not 
unique.
* Drop `hashAlgo' attribute in manifests; prefix hashes with the hash
  algorithm instead.
 2005-03-14 15:09:53 +00:00
Eelco Dolstra 8376fff151 * Add a version number to manifests. 2005-02-25 16:12:52 +00:00
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).
 2005-02-24 17:36:42 +00:00
Eelco Dolstra 98df735b51 * Propagate the deriver of a path through the substitute mechanism. 
* Removed some dead code (successor stuff) from nix-push.
* Updated terminology in the tests (store expr -> drv path).
* Check that the deriver is set properly in the tests.
 2005-02-09 12:57:13 +00:00
Eelco Dolstra 48ebe4527e * Better error reporting in readmanifest. 
* Use force flag in `mv' to prevent silly interactive questions (this
  happens with shared Nix stores).
 2005-02-08 11:40:19 +00:00
Eelco Dolstra 066da4ab85 * Really fix the substitute mechanism, i.e., ensure the closure 
invariant by registering references through the manifest.
* Added a test for nix-pull.
 2005-01-25 17:08:52 +00:00
Eelco Dolstra 6270aa727d * Propagate patches from the source distribution to the destination 
distribution insofar they are applicable.
 2004-12-29 22:17:26 +00:00
Eelco Dolstra 2fdb27e7f2 * Atomic file replacement is good. 2004-12-29 19:04:21 +00:00
Eelco Dolstra e1e9c036f9 * A utility to generate patches between releases based on their 
manifests.
 2004-12-29 18:58:15 +00:00
Eelco Dolstra 4bf58d5379 * Added a function to write manifests. 2004-12-28 21:11:28 +00:00
Eelco Dolstra 3d1b2101cc * Place manifests in /nix/var/nix/manifests. 
* Use the new patch downloader.
 2004-12-20 16:38:50 +00:00
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 99da51d4de * Show error messages from curl. 2004-10-20 14:05:48 +00:00
Eelco Dolstra 37ee6cef99 * Adapted nix-pull to use the new substitute mechanism. 2004-06-21 09:51:23 +00:00
Eelco Dolstra 03f1d1ecb5 * Switched from wget to curl. 
* Made the dependencies on bzip2 and the shell explicit.
 2004-04-06 08:18:51 +00:00
Eelco Dolstra 92e832348d * Lots of manual stuff. Reference pages for most Nix commands. 
* nix-pull now requires the full url to the manifest, i.e.,
  `/MANIFEST/' is no longer automatically appended.
* nix-prefetch-url works again.
 2004-02-10 16:14:47 +00:00
Eelco Dolstra b1c5f3c10d * Doh! Edited readmanifest.pm' instead of readmanifest.pm.in'. 2004-01-16 14:54:39 +00:00
Eelco Dolstra 06c5a7075d * Refactoring: put the manifest-reading code in a separate file. 2003-12-05 11:25:38 +00:00
