This repository contains the source code used for the App Engine Flexible Environment Python Compat (multicore) runtime, corresponding to env:flex
+ runtime: python-compat
in your app.yaml
. This runtime provides best effort compatibility with applications written to target the App Engine Standard Environment with Python 2.7. This runtime is deprecated and incomplete.
Do not use this runtime for new development. If you are using this runtime, you should expediently migrate to the vanilla Python runtime before November 2017.
By default the multi-process version of the runtime is launched via the Gunicorn webserver and is configured to use gevent-based concurrency and a number of processes equal to the number of CPU cores available.
This can be changed by creating a file called gunicorn.conf.py
in your
application's root directory, which will override the default
gunicorn.conf.py
included with this project. Refer the gunicorn documentation for details.
This runtime is deprecated and incomplete. Only critical bug fixes are planned.
Notably:
app.yaml
that are flagged as login: required
or login: admin
are not supported. Attemping to access these handlers will result in a 404 as the handlers will not be registered.threadsafe: false
in app.yaml
is ignored. Your application must either be threadsafe or you much change the gunicorn configuration to use sync workers.There may be other features that are not implemented or not functional in this version.
