Jelle Zijlstra updated THRIFT-4002: ----------------------------------- Attachment: thrift-hashable-exc.patch > Thrift exceptions are not hashable in Python 3 > ---------------------------------------------- > > Key: THRIFT-4002 > URL: https://issues.apache.org/jira/browse/THRIFT-4002 > Project: Thrift > Issue Type: Bug > Components: Python - Compiler > Reporter: Jelle Zijlstra > Labels: compiler, python > Attachments: thrift-hashable-exc.patch > > > The Thrift-to-Python compiler generates `__eq__` but not `__hash__` for > Thrift exception classes, which makes them not hashable in Python 3. Due to > http://bugs.python.org/issue28603, this can lead the Python standard library > to throw an error while printing tracebacks involving Thrift exceptions. > The attached patch generates `__hash__` for Thrift exceptions. This can > technically be incorrect since Thrift exceptions are mutable (compare > https://issues.apache.org/jira/browse/THRIFT-162), but in practice it seems > unlikely that people would mutate exception instances other than directly > after creating them, and without this patch some Thrift exceptions cannot be > displayed by the standard library. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
