James E. King III resolved THRIFT-4405.
---------------------------------------
Resolution: Fixed
Fix Version/s: 0.13.0
> Incorrect handling of sequence numbers that wrap to negative
> ------------------------------------------------------------
>
> Key: THRIFT-4405
> URL: https://issues.apache.org/jira/browse/THRIFT-4405
> Project: Thrift
> Issue Type: Improvement
> Components: Test Suite
> Affects Versions: 0.11.0
> Environment: docker ubuntu-xenial
> Reporter: James E. King III
> Assignee: James E. King III
> Priority: Major
> Fix For: 0.13.0
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> The following tests were added:
> * The cpp client for cross test did not use sequence numbers, so I added a
> testing protocol layer for TestClient on top of all protocols that uses a
> sequence ID that starts at INT32_MAX - 10, and advances until it wraps
> around. This caught a number of negative value handling issues.
> * The cpp client verifies the sequence ID that returns matches what was sent.
> * The python client was changed to use pedantic sequence ID checking on all
> protocols.
> The following errors were identified and fixed:
> * In c_glib, thrift_stored_message_protocol was limiting the sequence ID to
> [0..G_INTMAX]. This was changed to allow any 32-bit value, matching other
> implementations.
> * In cpp, JSON protocol, when the server read the header, it used a uint64_t
> for processing; this interacted with a bugfix from 2017 (THRIFT-4138) that
> dropped boost::lexical_cast and switched to std::stringstream, and this
> corrupted the negative sequence ID.
> * In python, compact protocol, a negative sequence ID was not handled
> properly because it is read in and written out as a "var int" which is always
> positive.
> Documentation was added for sequence number handling.
