83647f4ef1 * Simplify the implementation of "derivation" a bit: lift out the
common attribution so that they're evaluated only once, etc.  Note
  that the default output is now the first element of the "outputs"
  attribute, rather than the first element of the sorted list of
  outputs.  This seems more user-friendly.

921111d197 * Move the implementation of the ‘derivation’ primop into a separate
file.

48cea0d01e * Refactoring: Get rid of a few subdirectories in corepkgs/, and some
other simplifications.
* Use <nix/...> to locate the corepkgs.  This allows them to be
  overriden through $NIX_PATH.
* Use bash's pipefail option in the NAR builder so that we don't need
  to create a temporary file.

and ‘--realise’ actions).

b1004f40f7 * Reject a build if there is a cycle among the outputs. This is
necessary because existing code assumes that the references graph is
  acyclic.

Eelco Dolstra
b33da599c5 * In the garbage collector, delete invalid paths before deleting
unreachable paths.  This matters when using --max-freed etc.:
  unreachable paths could become reachable again, so it's nicer to
  keep them if there is "real" garbage to be deleted.  Also, don't use
  readDirectory() but read the Nix store and delete invalid paths in
  parallel.  This reduces GC latency on very large Nix stores.

66c99b0cf5 * ‘--disable-shared’ is no longer supported. Fortunately it's not
needed for the coverage analysis.

2aac7cd021 * Another case of lock file permissions being too liberal. 2011-12-21 19:17:45 +00:00
Eelco Dolstra
4d728bc3e6 * Security: make sure the lock files used by build-remote.pl are not
readable to other users.  Otherwise, any user can open the lock file
  for reading and lock it, thus DoSing the remote build mechanism.

Eelco Dolstra
69d6f0936a * Use a lock to ensure that only one build-remote instance can copy a
closure to a given machine at the same time.  This prevents the case
  where multiple instances try to copy the same missing store path to
  the target machine, which is very wasteful.

5679041132 * The ‘foo.drvPath’ feature was already broken in read-only mode.
Since it's rarely used and fixing it is too much work right now,
  just document it.

f3c88f297d Detect and reject mutually-referential outputs
There is probably a more efficient way to do this.

4be5a2c096 * Add a test for unsafeDiscardOutputDependency. Not really related to
multiple outputs, but good to have anyway.

179409b911 * Add a test for referring to another derivation's ‘drvPath’. This
currently fails in read-only mode.

1f3b0ede7d * Add a (currently failing) test that checks whether mutually
recursive outputs are properly rejected.
* Add a (also failing) test for "nix-build -A <output-name>".

273b288a7e * importPath() -> importPaths(). Because of buffering of the input
stream it's now necessary for the daemon to process the entire
  sequence of exported paths, rather than letting the client do it.

8d3dfa2c17 * Avoid expensive conversions from char arrays to STL strings. 2011-12-16 21:29:46 +00:00
Eelco Dolstra
e0bd307802 * Make the import operation through the daemon much more efficient
(way fewer roundtrips) by allowing the client to send data in bigger
  chunks.
* Some refactoring.

78598d06f0 * Clean up exception handling. 2011-12-16 15:45:42 +00:00
Eelco Dolstra
5a1b9ed0aa * Refactoring: move sink/source buffering into separate classes.
* Buffer the HashSink.  This speeds up hashing a bit because it
  prevents lots of calls to the hash update functions (e.g. nix-hash
  went from 9.3s to 8.7s of user time on the closure of my
  /var/run/current-system).

Eelco Dolstra
a3e0656cbb * Buffer reads in FdSource. Together with write buffering, this
significantly cuts down the number of syscalls (e.g., for "nix-store
  -qR /var/run/current-system" via the daemon, it reduced the number
  of syscalls in the client from 29134 to 4766 and in the daemon from
  44266 to 20666).
2011-12-15 12:32:08 +00:00
Eelco Dolstra
3a48282b06 * Buffer writes in FdSink. This significantly reduces the number of
system calls / context switches when dumping a NAR and in the worker
  protocol.

893cac1402 * Remove the terminate handler, which was only really needed because
of Berkeley DB (see r8632).

23bf700196 * Oops, the daemon test wasn't actually using the daemon. 2011-12-14 22:31:31 +00:00

c8c0380744 * Remove unnecessary quotes. showPaths() already adds quotes. 2011-12-05 21:04:20 +00:00
