Eelco Dolstra a71d02440b * Oops. 2011-12-30 17:13:25 +00:00
Eelco Dolstra 6f5e3326ce * Move topoSortPaths() out of gc.cc. 2011-12-30 15:02:50 +00:00
Eelco Dolstra 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.
 2011-12-30 14:47:14 +00:00
Eelco Dolstra ed11b17b2e * Fix doc error. 2011-12-30 13:43:29 +00:00
Eelco Dolstra 254b3399ba * Sync with the trunk. 2011-12-30 13:08:14 +00:00
Eelco Dolstra 8c42a8c8ff * Make sure that lock files are cleaned up properly when building 
through the build hook.
 2011-12-25 16:38:37 +00:00
Eelco Dolstra 524fa8a4f1 * Oops. 2011-12-22 16:27:03 +00:00
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.
 2011-12-22 15:55:53 +00:00
Eelco Dolstra 58d974336c * Drop unnecessary call to canonPath() (nixStore is already canonical). 2011-12-22 14:33:34 +00:00
Eelco Dolstra 66c99b0cf5 * ‘--disable-shared’ is no longer supported. Fortunately it's not 
needed for the coverage analysis.
 2011-12-22 10:58:27 +00:00
Eelco Dolstra 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.
 2011-12-21 19:11:58 +00:00
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.
 2011-12-21 18:59:25 +00:00
Eelco Dolstra 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.

Shea Levy f8e54b7874 Make the reference cycle in the cyclic outputs test indirect 2011-12-21 17:34:44 +00:00
Shea Levy b4cee3f816 Revert previous commit 
It doesn't detect indirect references
 2011-12-21 17:31:34 +00:00
Shea Levy f3c88f297d Detect and reject mutually-referential outputs 
There is probably a more efficient way to do this.
 2011-12-21 17:14:28 +00:00
Eelco Dolstra b19a0f63db * Simplify the context handling logic. 2011-12-21 15:33:30 +00:00
Eelco Dolstra 4be5a2c096 * Add a test for unsafeDiscardOutputDependency. Not really related to 
multiple outputs, but good to have anyway.
 2011-12-21 14:42:06 +00:00
Eelco Dolstra 179409b911 * Add a test for referring to another derivation's ‘drvPath’. This 
currently fails in read-only mode.
 2011-12-21 13:47:21 +00:00
Eelco Dolstra 3877619888 * Add some accidentally committed files. 2011-12-21 11:47:52 +00:00
Eelco Dolstra edd9359beb * Doing a GC after building a derivation with cyclic outputs currently 
segfaults.
 2011-12-20 17:10:39 +00:00
Eelco Dolstra 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>".
 2011-12-20 17:08:43 +00:00
Eelco Dolstra 46e42c92c1 * Refactor a bit so that more tests can be added. 2011-12-20 17:01:02 +00:00
Eelco Dolstra b5363810bb * Fix the build. 2011-12-20 16:37:01 +00:00
Eelco Dolstra 194d21f9f6 * Sync with the trunk. 2011-12-16 23:33:01 +00:00
Eelco Dolstra 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.
 2011-12-16 22:31:25 +00:00
Eelco Dolstra 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.
 2011-12-16 19:44:13 +00:00
Eelco Dolstra 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).
 2011-12-15 16:19:53 +00:00
Eelco Dolstra a67b8ae224 * Typo. 2011-12-15 14:04:35 +00:00
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.
 2011-12-14 23:30:06 +00:00
Eelco Dolstra 893cac1402 * Remove the terminate handler, which was only really needed because 
of Berkeley DB (see r8632).
 2011-12-14 22:41:10 +00:00
Eelco Dolstra 23bf700196 * Oops, the daemon test wasn't actually using the daemon. 2011-12-14 22:31:31 +00:00
Eelco Dolstra c8c0380744 * Remove unnecessary quotes. showPaths() already adds quotes. 2011-12-05 21:04:20 +00:00
Eelco Dolstra 000160f5b9 * In ‘nix-store --verify --check-contents’, repair missing hashes 
rather than complain about them.
 2011-12-02 17:52:18 +00:00
Eelco Dolstra 3964d95abf * nix-prefetch-url: rewritten in Perl. 2011-12-02 12:09:50 +00:00
Eelco Dolstra 92d6a5ed73 * Add some more functions to the Perl bindings. 2011-12-02 12:09:24 +00:00
Eelco Dolstra 49f59dceca * Move parseHash16or32 into libutil, and use in nix-hash. 2011-12-02 11:47:06 +00:00
Eelco Dolstra b12b21825c * Allow '<nixexpr>' syntax to be used in nix-instantiate, nix-build 
and nix-env, e.g.,

  $ nix-env -f '<nixpkgs>' -i patchelf

  or

  $ nix-build '<nixos/tests>' -A login.test
 2011-12-01 16:41:43 +00:00
Eelco Dolstra 23c38a04cc * Slight improvement. 2011-12-01 13:51:05 +00:00
Eelco Dolstra 24f863d86b * When doing "nix-store --add-fixed" without "--recursive" via the Nix 
daemon (which is an error), print a nicer error message than
  "Connection reset by peer" or "broken pipe".
* In the daemon, log errors that occur during request parameter
  processing.

Eelco Dolstra f35c4351e5 * Don't require a specific Perl version. 2011-11-29 22:15:07 +00:00
Eelco Dolstra 4d0407ba08 * Fix make check. 2011-11-29 13:38:52 +00:00

Eelco Dolstra b1eb8f4249 * Get rid of some superfluous error messages if a substituter fails. 
* Say "fetch" instead of "substitute".
