thirdparty: vendor futures 3.2.0...
thirdparty: vendor futures 3.2.0 Python 3 has a concurrent.futures package in the standard library for representing futures. The "futures" package on PyPI is a backport of this package to work with Python 2. The wire protocol code today has its own future concept for handling of "batch" requests. The frame-based protocol will also want to use futures. I've heavily used the "futures" package on Python 2 in other projects and it is pretty nice. It even has a built-in thread and process pool for running functions in parallel. I've used this heavily for concurrent I/O and other GIL-less activities. The existing futures API in the wire protocol code is not as nice as concurrent.futures. Since concurrent.futures is in the Python standard library and will presumably be the long-term future for futures in our code base, let's vendor the backport so we can use proper futures today. # no-check-commit because of style violations Differential Revision: https://phab.mercurial-scm.org/D3261
