The codebase is filled with includes that are unused, and which thus can be removed. At the same time, the files often do not include all headers that contain the definitions used in those files. This change uses clang-format and clang-tidy to clean up the includes, with minor manual intervention to ensure the code compiles on all platforms.
This is a refactor aimed at cleaning up and simplifying the existing
job queue.
As of now, all jobs are cancelled at the same time and in the same
way, so this commit removes the per-job cancellation token. If the
need for such support is demonstrated, support can be re-added.
* Revise documentation for ClosureCounter and Workers.
* Simplify code, removing unnecessary function arguments and
deduplicating expressions
* Restructure job handlers to no longer need to pass a job's
handle to the job.
The existing calculation would limit the maximum number of threads
that would be created by default to at most 6; this may have been
reasonable a few years ago, but given both the load on the network
as of today and the increase in the number of CPU cores, the value
should be revisited.
This commit, if merged, changes the default calculation for nodes
that are configured as `large` or `huge` to allow for up to twelve
threads.
