* 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 13:57:13 +01:00			`drvPath=$($TOP/src/nix-instantiate/nix-instantiate 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 19:04:17 +02:00

* 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. TODO: substitutes are currently broken. 2004-05-11 20:05:44 +02:00			`if test "$text" != "abacade"; then exit 1; fi`
