Xena Series Release Notes

2.6.2

Bug Fixes

  • Fix the backdoor helper method fo() to also work when there are objects present in the current python instance that do not have a __class__ attribute.

2.6.1

New Features

  • A new config options, [DEFAULT] wsgi_server_debug, has been added. This allows admins to configure whether the server should send exception tracebacks to the clients on HTTP 500 errors. This defaults to False, preserving previous behavior.

2.0.0

Upgrade Notes

  • Support for Python 2.7 has been dropped. The minimum version of Python now supported is Python 3.6.

1.40.2

Bug Fixes

  • SIGHUP is now handled properly with restart_method='mutate', no longer restarting child processes. See bug 1794708 for details. In conjunction with the fix for bug 1715374 in oslo.privsep, the nova-compute service now behaves correctly when it receives SIGHUP.

1.40.0

New Features

  • The config option backdoor_socket_path now is a format string that supports {pid}, which will be replaced with the PID of the current process. This makes the eventlet backdoor accessible when spawning multiple processes with the same backdoor_socket_path inside the configuration.

1.37.0

New Features

  • Add support for profiling (capture function calltrace) service’s worker processes.

1.35.0

New Features

  • The ThreadGroup class has new add_timer_args() and add_dynamic_timer_args() methods to create timers passing the positional and keyword arguments to the callback as a sequence and a mapping. This API provides more flexibility for the addition of timer control options in the future.

  • The ThreadGroup add_timer_args() and add_dynamic_timer_args() methods now support passing a stop_on_exception=False argument to allow the timer to keep running even when an exception is raised by the callback function.

Deprecation Notes

  • The ThreadGroup.cancel() method is deprecated and will be removed in a future major release.

  • The API of the ThreadGroup add_timer() and add_dynamic_timer() methods has been identified as error-prone when passing arguments intended for the callback function. Passing callback arguments in this way is now deprecated. Callers should use the new add_timer_args() or add_dynamic_timer_args() methods (respectively) instead when it is necessary to pass arguments to the timer callback function.

1.19.0

New Features

  • Add a new type of looping call: FixedIntervalWithTimeoutLoopingCall. It is a FixedIntervalLoopingCall with timeout checking.

1.17.0

Other Notes

  • Switch to reno for managing release notes.
