Eelco Dolstra 0a0c1fcb4d * The `-v' flag no longer takes an argument; it should be repeated
instead (e.g., `-vvvv' for lots of output).  Default is to only
  print error messages.
2003-07-24 13:43:16 +00:00
Eelco Dolstra 1a7468a57a * Debug levels. Use `--verbose / -v LEVEL' to display only messages
up to the given verbosity levels.  These currently are:

    lvlError = 0, 
    lvlNormal = 5,
    lvlDebug = 10,
    lvlDebugMore = 15

  although only lvlError and lvlDebug are actually used right now.

Eelco Dolstra df648c4967 * nix --query --expansion' (-qe') to get any path with content
corresponding to the given id.
2003-07-22 10:24:22 +00:00
Eelco Dolstra d5ee6f8700 * In `--query --generators', print out paths, not ids.
(There should really be a switch for this).

Eelco Dolstra 49231fbe41 * Changes to the command line syntax of Nix.
* A function to find all Nix expressions whose output ids are
  completely contained in some set.  Useful for uploading relevant Nix
  expressions to a shared cache.
2003-07-21 14:46:01 +00:00
Eelco Dolstra 7984cfc7c1 * Argh, another short-write problem. Added wrappers around
read()/write() to fix this once and for all.

Eelco Dolstra 6f1a0f948d * Refactorings. 2003-07-20 19:29:38 +00:00
Eelco Dolstra b3fc38bf6a * For debugging: `nix --verify' to check the consistency of the
database and store.
2003-07-17 12:27:55 +00:00
Eelco Dolstra 54664b6fb7 * The write() system call can write less than the requested
number of bytes, e.g., in case of a signal like SIGSTOP.  
  This caused `nix --dump' to fail sometimes.

  Note that this bug went unnoticed because the call to `nix 
  --dump' is in a pipeline, and the shell ignores non-zero 
  exit codes from all but the last element in the pipeline.  
  Is there any way to check the result of the initial elements
  in the pipeline?  (In other words, is it at all possible to 
  write reliable shell scripts?)

Eelco Dolstra d41d085b77 * Get Fix and Nix to work again. 2003-07-15 22:28:27 +00:00
Eelco Dolstra c834a5c597 * Fix handling of pipes (read(2) may not return the required
number of bytes in one call).
2003-07-11 08:16:15 +00:00
Eelco Dolstra e5fbf58041 * A command to register successor fstate expressions.
Unifying substitutes and successors isn't very feasible for now,
  since substitutes are only used when no path with a certain is
  known.  Therefore, a normal form of some expression stored as a
  substitute would not be used unless the expression itself was
  missing.
2003-07-10 18:48:11 +00:00
Eelco Dolstra 1d1c3691d2 * The policy-free derivate sharing now *almost* works. :-) For any
hash for which no local expansion is available, Nix can execute a
  `substitute' which should produce a path with such a hash.

  This is policy-free since Nix does not in any way specify how the
  substitute should work, i.e., it's an arbitrary (unnormalised)
  fstate expression.  For example, `nix-pull' registers substitutes
  that fetch Nix archives from the network (through `wget') and unpack
  them, but any other method is possible as well.  This is an
  improvement over the old Nix sharing scheme, which had a policy
  (fetching through `wget') built in.

  The sharing scheme doesn't work completely yet because successors
  from fstate rewriting have to be registered on the receiving side.
  Probably the whole successor stuff can be folded up into the
  substitute mechanism; this would be a nice simplification.

Eelco Dolstra d072485d28 * Get `nix-push' working again. It now uses Nix/Fix to create Nix
archives (using the package in corepkgs/nar).
* queryPathByHash -> expandHash, and it takes an argument specifying
  the target path (which may be empty).
* Install the core Fix packages in $prefix/share/fix.  TODO: bootstrap
  Nix and install Nix as a Fix package.
2003-07-10 13:41:28 +00:00
Eelco Dolstra 2b95a9dc05 * When computing the set of paths referenced by an expression, also
include the paths of the subterms.
2003-07-09 15:02:03 +00:00

Eelco Dolstra 40274c1f4f * A command to query the paths referenced by an fstate expression.
* Use a temporary directory for build actions.

Eelco Dolstra 8b930a0c94 * Some refactoring. 2003-05-26 13:45:00 +00:00
Eelco Dolstra f8d91f20e6 * Nix can now fetch prebuilts (and other files) from the network, iff
a mapping from the hash to a url has been registered through `nix
  regurl'.

* Bug fix in nix: don't pollute stdout when running tar, it made
  nix-switch barf.

* Bug fix in nix-push-prebuilts: don't create a subdirectory on the
  target when rsync'ing.
2003-05-26 09:44:18 +00:00
Eelco Dolstra 7dd91d3779 * Prebuilt package sharing. We allow transparent binary deployment by
sharing package directories (i.e., the result of building a Nix
  descriptor).

  `nix-pull-prebuilts' obtains a list of all known prebuilts by
  consulting the paths and URLs specified in
  $prefix/etc/nix/prebuilts.conf.  The mappings ($pkghash,
  $prebuilthash) and ($prebuilthash, $location) are registered with
  Nix so that it can use the prebuilt with hash $prebuilthash when
  installing a package with hash $pkghash by downloading and unpacking
  $location.

  `nix-push-prebuilts' creates prebuilts for all packages for which no
  prebuilt is known to exist.  It can then optionally upload these
  to the network through rsync.

  `nix-[pull|push]-prebuilts' just provide a policy.  Nix provides the
  mechanism through the `nix [export|regprebuilt|regurl]' commands.
