-----------------------------------
Summary: Regression in 0.11: Arrays with default values in python
Key: THRIFT-4510
URL: https://issues.apache.org/jira/browse/THRIFT-4510
Project: Thrift
Issue Type: Bug
Components: Python - Compiler
Affects Versions: 0.11.0
Reporter: Jason Gauci
We are getting reports from users that our project is broken on thrift 0.11.
Arrays with default values are newly broken in 0.11 because thrift_spec is not
defined soon enough.
To reproduce:
brew install thrift
git clone [https://github.com/caffe2/BlueWhale.git]
cd BlueWhale
thrift --gen py --out . ml/rl/thrift/core.thrift
cat ml/rl/thrift/core/ttypes.py
Notice that the TrainingParameters.__init__ tries to use thrift_spec to handle
the default array when thrift_spec doesn't exist yet. This results in this
failure upon import:
AttributeError: 'TrainingParameters' object has no attribute 'thrift_spec'
The same thing works when using 0.10
