update python compiler to parse unions, * namespaces and oneway services
------------------------------------------------------------------------
Key: THRIFT-1262
URL: https://issues.apache.org/jira/browse/THRIFT-1262
Project: Thrift
Issue Type: Improvement
Components: Python - Compiler
Reporter: Will Pierce
Attachments: THRIFT-1262-python_compiler_revival_v1.patch
This patch adds python-compiler parser support for Unions, "*" namespaces, and
oneway services in thrift files. The python compiler is still incomplete (it
doesn't generate a valid thrift_spec member in the code text it outputs), but
this helps bring it a little up to date with "newer" features of Thrift that
presumable didn't exist when the python compiler was last touched (January
2009).
This is a patch against the branches/py-compiler/ directory, not trunk/... If
there's a better way to submit fixes to the python compiler, please let me
know. Or maybe this should be moved into trunk instead? (The SVN commit
message on the py-complier branch is "Snapshot (back up) my work-in-progress
before I hop on a plane.:" from gstein.)
The various changes here include:
* adding SYM_STAR as a recognized symbol (for * namespaces)
* adding Union as a subclass of Struct
* parser.py is now executable w/ some debug output
* fix up absolute pathing in gen.py so it doesn't rely on
/Users/gstein/src/asf/...
* slight improvement to UnknownToken exception output (line number better
labeled)
* fix bug in handling of the service 'extends' keyword
* fix redefinition of Exception class
* add some repr() methods to make debugging output a little more readable
