  • 51e46c7a4   docs, parallelism: Rearrange how jobserver reservations are made ... Browse Code ยป

    Rasmus correctly observed that the existing jobserver reservation only
    worked if no other build targets were specified. The correct approach
    is to hold the jobserver slots until sphinx has finished. To fix this,
    the following changes are made:

    - refactor (and rename) scripts/jobserver-exec to set an environment
    variable for the maximally reserved jobserver slots and exec a
    child, to release the slots on exit.

    - create Documentation/scripts/parallel-wrapper.sh which examines both
    $PARALLELISM and the detected "-jauto" logic from Documentation/Makefile
    to decide sphinx's final -j argument.

    - chain these together in Documentation/Makefile
