  1. Lock paths in the scm cache

    This is necessary now that hydra-evaluator runs multiple evaluations
    in parallel, to prevent corruption of Git/Mercurial clones.

  2. hydra-evaluator: Handle SIGINT

    This makes "systemctl stop hydra-evaluator" work promptly again.

  3. Move most of AddBuilds to hydra-eval-jobset

    Having this stuff in a separate module is a remnant of the time when
    hydra-server could add builds to the queue directly. This is no longer
    the case.

  1. Allow determinism checking for entire jobsets

      xxx-jobset-repeats = patchelf:master:2
    will cause Hydra to perform every build step in the specified jobset 2
    additional times (i.e. 3 times in total). Non-determinism is not fatal
    unless the derivation has the attribute "isDeterministic = true"; we
    just note the lack of determinism in the Hydra database. This will
    allow us to get stats about the (lack of) reproducibility of all of

  1. Support testing build determinism

    Builds can now specify the attribute "isDeterministic = true" to tell
    Hydra to build with build-repeat > 0. If there is a mismatch between
    rounds, the step / build fails with a suitable status.
    Maybe this should be a meta attribute, but that makes it invisible to
    hydra-queue-runner, and it seems reasonable to make a claim of
    mandatory determinism part of the derivation (since e.g. enabling this
    flag should trigger a rebuild).

  2. hydra-queue-runner: More accurate memory accounting

    We now take into account the memory necessary for compressing the NAR
    being exported to the binary cache, plus xz compression overhead.
    Also, we now release the memory tokens for the NAR accessor *after*
    releasing the NAR accessor. Previously the memory for the NAR accessor
    might still be in use while another thread does an allocation, causing
    the maximum to be exceeded temporarily.
    Also, use notify_all instead of notify_one to wake up memory token
    waiters. This is not very nice, but not every waiter is requesting the
    same number of tokens, so some might be able to proceed.

  1. hydra-queue-runner: Fix a race keeping cancelled steps alive

    If a step is cancelled just as its builder step is starting,
    doBuildStep() will return sRetry. This causes builder() to make the
    step runnable again, since the queue monitor may have added new builds
    referencing it. The idea is that if the latter condition is not true,
    the step's reference count will drop to zero and it will be
    deleted. However, if the dispatcher thread sees and locks the step
    before the reference count can drop to zero in the builder thread, the
    dispatcher thread will start a new builder thread for the step. Thus
    the step can be kept alive for an indefinite amount of time.
    The fix is for State::builder() to use a weak pointer to the step, to
    ensure that the step's reference count can drop to zero *before* it's
    added to the runnable queue.

  1. Step cancellation: Don't use pthread_cancel()

    This was a bad idea because pthread_cancel() is unsalvageable broken
    in C++. Destructors are not allowed to throw exceptions (especially in
    C++11), but pthread_cancel() can cause a __cxxabiv1::__forced_unwind
    exception inside any destructor that invokes a cancellation
    point. (This exception can be caught but *must* be rethrown.) So let's
    just kill the builder process instead.
