This release of the Python agent includes a hot fix to address an issue whereby external web service calls made via HTTPS connections were failing. This issue was introduced with version 22.214.171.124 of the agent.
For a list of known issues with the Python agent see our online help article on the status of the Python agent.
- The Cross Application Tracing feature added in version 126.96.36.199 of the agent was causing failure of external web service calls made over HTTPS connections when that call was made via the 'httplib' module. As the 'httplib' module is used internally in other HTTP client libraries such as the 'urllib', 'urllib2', 'urllib3' and 'requests' modules, they would also have been affected.
- Setting the 'cross_application_tracer.enabled' setting in the agent configuration file to 'false' to disable Cross Application Tracing would cause an exception when an external web service call was being made via the 'httplib' module.
