------------------------------------------
Summary: TProcessPoolServer does not shutdown cleanly
Key: THRIFT-1617
URL: https://issues.apache.org/jira/browse/THRIFT-1617
Project: Thrift
Issue Type: Bug
Components: Python - Library
Affects Versions: 0.8
Environment: linux, but I assume all
Reporter: Jonathan Kaczynski
I haven't been able to get TProcessPoolServer to shutdown cleanly.
I tried stopping TProcessPoolServer in the finally clause of a try-block around
server.serve(), [https://gist.github.com/2828980], but the child processes
became orphaned.
Then, I tried using the code from the test I found,
http://svn.apache.org/repos/asf/thrift/trunk/test/py/TestServer.py, but the
processes still didn't terminate: https://gist.github.com/2829045
I commented on THRIFT-1083, and Dvir responded with an updated version of
TProcessPoolServer.py:
[THRIFT-1083|https://issues.apache.org/jira/browse/THRIFT-1083?focusedCommentId=13280566&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13280566].
Here's how I'm using it: https://gist.github.com/2771144
I'm sending the parent process the TERM signal, and noticed two issues:
1. The child processes won't terminate until they have attempted to field a
request. If server.stop() is called before it has fielded a request, the child
process will continue running until it services a request and then it will
shutdown.
2. The parent process never shuts down.
