2004-05-13	* Set the executable bit.	Eelco Dolstra	1	-0/+0

2004-05-13	* Perform all tests.	Eelco Dolstra	1	-4/+2

2004-05-13	* The build hooks used to implement distributed builds can now be run	Eelco Dolstra	4	-10/+16
	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.
2004-05-12	* Use `-j0'.	Eelco Dolstra	1	-8/+1

2004-05-12	* A switch `-j NUMBER' to set the maximum number of parallel jobs (0 =	Eelco Dolstra	1	-1/+1
	no limit). * Add missing file to distribution.
2004-05-12	* Broken test.	Eelco Dolstra	1	-3/+3

2004-05-12	* An quick and dirty hack to support distributed builds.	Eelco Dolstra	4	-2/+59

2004-05-11	* True parallel builds. Nix can now run as many build jobs in	Eelco Dolstra	4	-14/+13
	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.
2004-05-04	* A test to verify that Nix executes build jobs in parallel, if	Eelco Dolstra	4	-3/+80
	possible. This test fails right now because this hasn't been implemented right now. Yes, I'm doing Test-Driven Development! ;-)
2004-05-04	* 1000th revision!	Eelco Dolstra	4	-2/+50
	* A test to verify that locking of output paths (caused by concurrent invocations of Nix) works correctly.
2004-05-04	* Another test.	Eelco Dolstra	6	-2/+66

2004-05-04	* Grrr. TESTS are not included in EXTRA_DIST.	Eelco Dolstra	1	-1/+1

2004-05-04	* Allow the location of the store etc. to be specified using	Eelco Dolstra	5	-0/+64
	environment variables. * Started adding some automatic tests. * Do a `make check' when building RPMs.
