Backport of the concurrent.futures package from Python 3
.. image:: https://travis-ci.org/agronholm/pythonfutures.svg?branch=master :target: https://travis-ci.org/agronholm/pythonfutures :alt: Build Status
This is a backport of the concurrent.futures
_ standard library module to Python 2.
It does not work on Python 3 due to Python 2 syntax being used in the codebase. Python 3 users should not attempt to install it, since the package is already included in the standard library.
To conditionally require this library only on Python 2, you can do this in your setup.py
:
.. code-block:: python
setup(
...
extras_require={
':python_version == "2.7"': ['futures']
}
)
Or, using the newer syntax:
.. code-block:: python
setup(
...
install_requires={
'futures; python_version == "2.7"'
}
)
.. warning:: The ProcessPoolExecutor
class has known (unfixable) problems on Python 2 and
should not be relied on for mission critical work. Please see Issue 29 <https://github.com/agronholm/pythonfutures/issues/29>
_ and upstream bug report <https://bugs.python.org/issue9205>
_ for more details.
