------------------------------------
Summary: Thrift should provide deep-validation of structures
Key: THRIFT-1732
URL: https://issues.apache.org/jira/browse/THRIFT-1732
Project: Thrift
Issue Type: New Feature
Components: Python - Compiler
Affects Versions: 0.9
Environment: All.
Reporter: Avi Flamholz
Priority: Minor
The validate() method in Python does extremely shallow validation: it checks
only that required fields are not None. It does not check that field values
have the correct type or that embedded structures or collections are valid.
This is paltry validation as compared to IsInitialized() in the Python Protocol
Buffers implementation, which descends into embedded structures and checks that
they are valid. Not to mention that ProtocolBuffers also check value types on
assignment.
It is fairly simple to generate a deep_validate() method that will recursively
descend into structures and collections and call validate() on those which can
be validated. I've written something of the sort and I'm curious if it would be
a welcome addition to the Python generated code.
