What does the specifying jobs [1] in the _constraints file actually do? I expected it to work similarly as specifying 'osc build --jobs N' on the command line, but looking in the logs of a remote build server, it see that it actually runs with a higher number '+ /usr/bin/make -O VERBOSE=1 -j8'. Is there a way to limit the requested number of parallel build jobs in the _constraints file, or is the only way to put this in the spec file like '%cmake_build --jobs 4'?

it is the opposite, it is canceling out any worker which has less than X jobs configured. So the job will only be assigned to workers which are called using --jobs X during dispatching ...

I think the documentation could do with some clarification here. "To require a minimal number of pre-confiured parallel jobs for the build job. This limits the parallel wanted jobs for the build tooling, but is actually not a hardware requirement." As a native english speaker its pretty easy to interpret the second sentence as limiting the number of parallel jobs that can run. Is there a good place to create bug reports for obs documentation?

You can use the %limit_build macro (from the memory-constraints package) to limit the number of jobs according to the given memory consumption. That takes the available memory on the worker into account, so that a bigger worker may run with more jobs. -- Andreas Schwab, SUSE Labs, schwab@suse.de GPG Key fingerprint = 0196 BAD8 1CE9 1970 F4BE 1748 E4D4 88E3 0EEA B9D7 "And now for something completely different."

This was exactly what I was looking for, thanks!
