* Make it easy to run individual tests from the command line. 2006-03-01 14:15:33 +02:00			`source common.sh`

* Clean up some tests (use nix-build where appropriate). 2009-03-18 15:15:55 +02:00			`clearStore`
* 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! ;-) 2004-05-04 20:04:17 +03:00

* 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.
