Before it was possible for precompiled binaries of the Cython layer to
be downloaded during a test run if the metadata of the host machine's
gRPC Python project matched the metadata of a file in cloud storage. Now
we disallow this, and fix a bug where the relevant environment variable
was ineffectual.
This reorganizes the Python code, scraps the current testing
infrastructure, and implements a simple test discovery and run script
based on the standard Python unittest library so we can trust that our
tests are running.
Allows:
- running python tests in parallel
- clearer Travis output
- subjects each python test to the five minute run_tests timeout,
instead of ALL the tests to the five minute timeout
- easier benchmarking of which tests are slow
This makes grpc.early_adopter much more independent of RPC
Framework and cleaner at the cost of reexporting most of the
interfaces and writing several delegation classes.
This provides for now what should be a nicer interface for code
generation than that of the Face layer. In terms of abstraction
it's conceptually very similar so the two should probably be
merged as soon as is reasonable.
The source code is moved from src/python to
src/python/src. A setup.py is added at
src/python. The build_python.sh and
run_python.sh scripts are updated to build
and run the Python tests by building a
package and installing it in the developer's
Python 2.7 virtual environment.
