Eelco Dolstra 3426d19547 * Perform all tests. 2004-05-13 19:16:48 +00:00
Eelco Dolstra a8306cb98f * The build hooks used to implement distributed builds can now be run
in parallel.  Hooks are more efficient: locks on output paths are
  only acquired when the hook says that it is willing to accept a
  build job.  Hooks now work in two phases.  First, they should first
  tell Nix whether they are willing to accept a job.  Nix guarantuees
  that no two hooks will ever be in the first phase at the same time
  (this simplifies the implementation of hooks, since they don't have
  to perform locking (?)).  Second, if they accept a job, they are
  then responsible for building it (on the remote system), and copying
  the result back.  These can be run in parallel with other hooks and
  locally executed jobs.

  The implementation is a bit messy right now, though.  

* The directory `distributed' shows a (hacky) example of a hook that
  distributes build jobs over a set of machines listed in a
  configuration file.

Eelco Dolstra 5087c8f645 * Use `-j0'. 2004-05-12 14:30:57 +00:00
Eelco Dolstra efa5fa1a91 * A switch `-j NUMBER' to set the maximum number of parallel jobs (0 =
no limit).
* Add missing file to distribution.

Eelco Dolstra 1f48aa0be7 * Broken test. 2004-05-12 13:49:10 +00:00
Eelco Dolstra 8c0b42f857 * An quick and dirty hack to support distributed builds. 2004-05-12 09:35:51 +00:00
Eelco Dolstra c8d3882cdc * True parallel builds. Nix can now run as many build jobs in
parallel as possible (similar to GNU Make's `-j' switch).  This is
  useful on SMP systems, but it is especially useful for doing builds
  on multiple machines.  The idea is that a large derivation is
  initiated on one master machine, which then distributes
  sub-derivations to any number of slave machines.  This should not
  happen synchronously or in lock-step, so the master must be capable
  of dealing with multiple parallel build jobs.  We now have the
  infrastructure to support this.

  TODO: substitutes are currently broken.

Eelco Dolstra a9858c9f26 * A test to verify that Nix executes build jobs in parallel, if
possible.

  This test fails right now because this hasn't been implemented right
  now.  Yes, I'm doing Test-Driven Development! ;-)

Eelco Dolstra f044ccf702 * 1000th revision!
* A test to verify that locking of output paths (caused by concurrent
  invocations of Nix) works correctly.

Eelco Dolstra a7bbe73971 * Another test. 2004-05-04 13:22:33 +00:00
Eelco Dolstra ef093aac8f * Grrr. TESTS are not included in EXTRA_DIST. 2004-05-04 12:45:04 +00:00
Eelco Dolstra 256eeab711 * Allow the location of the store etc. to be specified using
environment variables.
* Started adding some automatic tests.
* Do a `make check' when building RPMs.
