* Make it easy to run individual tests from the command line. 2006-03-01 12:15:33 +00:00			`source common.sh`

* Simplification. 2006-03-01 12:51:18 +00:00			`drvPath=$($nixinstantiate parallel.nix)`
* 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 17:04:17 +00:00
* Propagate the deriver of a path through the substitute mechanism. * Removed some dead code (successor stuff) from nix-push. * Updated terminology in the tests (store expr -> drv path). * Check that the deriver is set properly in the tests. 2005-02-09 12:57:13 +00:00			`echo "derivation is $drvPath"`

* 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. 2004-05-11 18:05:44 +00:00			`if test "$text" != "abacade"; then exit 1; fi`
