Yiyang Zhou created THRIFT-5449:
-----------------------------------
Summary: Use select.poll instead of select.select in Python
TNonblockingServer if available
Key: THRIFT-5449
URL: https://issues.apache.org/jira/browse/THRIFT-5449
Project: Thrift
Issue Type: Improvement
Components: Python - Library
Reporter: Yiyang Zhou
Currently Python TNonblockingServer uses select.select to monitor the IO of all
existing connections. The value of file descriptors monitored by select() is
limited to be lower than _FD_SETSIZE_ (1024). Any file desciptor higher than
1024, when passed into select.select, will trigger the "fd out of range" error.
Switching to select.poll can solve this problem. However, as noted in the
official documentation, select.poll is not supported in all operating system.
We should also check whether the current system has poll in the select module,
and use poll if it's available.
