Release Notes

Supervisor/supervisor (supervisor)

v4.3.0

Compare Source

• Fixed a bug where the poller would not unregister a closed
  file descriptor under some circumstances, which caused excessive
  polling, resulting in higher CPU usage. Patch by aftersnow.

• Fixed a bug where restarting supervisord may have failed with
  the message Error: Another program is already listening on a port that one of our HTTP servers is configured to use.
  if an HTTP request was made during restart. Patch by Julien Le Cléach.

• Fixed a unit test that failed only on Python 3.13. Only test code was
  changed; no changes to supervisord itself. Patch by Colin Watson.

• On Python 3.8 and later, setuptools is no longer a runtime
  dependency. Patch by Ofek Lev.

• On Python versions before 3.8, setuptools is still a runtime
  dependency (for pkg_resources) but it is no longer declared in
  setup.py as such. This is because adding a conditional dependency
  with an environment marker (setuptools; python_version < '3.8')
  breaks installation in some scenarios, e.g. setup.py install or
  older versions of pip. Ensure that setuptools is installed
  if using Python before 3.8.

v4.2.5

Compare Source

• Fixed a bug where the XML-RPC method supervisor.startProcess() would
  return 500 Internal Server Error instead of an XML-RPC fault response
  if the command could not be parsed. Patch by Julien Le Cléach.

• Fixed a bug on Python 2.7 where a UnicodeDecodeError may have occurred
  when using the web interface. Patch by Vinay Sajip.

• Removed use of urllib.parse functions splithost, splitport, and
  splittype deprecated in Python 3.8.

• Removed use of asynchat and asyncore deprecated in Python 3.10.

• The return value of the XML-RPC method supervisor.getAllConfigInfo()
  now includes the directory, uid, and serverurl of the
  program. Patch by Yellmean.

• If a subprocess exits with a unexpected exit code (one not listed in
  exitcodes= in a [program:x] section) then the exit will now be logged
  at the WARN level instead of INFO. Patch by Precy Lee.

• supervisorctl shutdown now shows an error message if an argument is
  given.

• File descriptors are now closed using the faster os.closerange() instead
  of calling os.close() in a loop. Patch by tyong920.
