Revision history [back]

I have gone through the following links for trying to setup my debugging environment for OpenStack Swift but haven't been able to do so far.

1. http://debugopenstack.blogspot.com/
2. https://ask.openstack.org/question/815/how-do-i-debug-nova-service-with-eclipse-and-pydev/

Following is my development environment configuration:

• Ubuntu 12.04 as the host OS (No VM).
• Ubuntu 12.04 as the guest OS running on VMWare Player.
• OpenStack has been successfully deployed on the guest OS using DevStack.

Following the aforementioned links, I have tried setting up my remote debugging environment as follows:

• Eclipse is installed on my host OS along with pydev.
• I have copied the pysrc folder from host OS to guest OS.
• Path of pysrc in guest OS is: /usr/lib/python2.7/site-packages/pysrc.
• Added line sys.path.append('/usr/lib/python2.7/site-packages/pysrc/') after import sys in the file swift-init located at /opt/stack/swift/bin.
• Added line import pydevd and pydevd.settrace("10.99.13.16", port=5678, stdoutToServer=True, stderrToServer=True,suspend=True) under the function def put(self, metadata, extension='.data') in file server.py located at '/opt/stack/swift/swift/obj to set a breakpoint.
• Started the debug server on my host OS. Now I am unable to execute stack.s script successfully and it gives the following errors at the end:

Errors:

Request returned failure status.
500 Internal Server Error
Failed to upload image
    (HTTP 500)
++ failed
++ local r=1
+++ jobs -p
++ kill
++ set +o xtrace

This error is obviously due to my addition of import line in the file server.py as commenting it out makes it work just fine.

Contents of my localrc file are:
