[dependabot]

Bumps supervisor from 4.2.1 to 4.2.3.

Changelog

Sourced from supervisor's changelog.

4.2.3 (2021-12-27)

• Fixed a race condition where an rpcinterface extension that subscribed to events would not see the correct process state if it accessed the the state attribute on a Subprocess instance immediately in the event callback. Patch by Chao Wang.

• Added the setuptools package to the list of dependencies in setup.py because it is a runtime dependency. Patch by Louis Sautier.

• The web interface will now return a 404 Not Found response if a log file is missing. Previously, it would return 410 Gone. It was changed because 410 is intended to mean that the condition is likely to be permanent. A log file missing is usually temporary, e.g. a process that was never started will not have a log file but will have one as soon as it is started.

4.2.2 (2021-02-26)

• Fixed a bug where supervisord could crash if a subprocess exited immediately before trying to kill it.

• Fixed a bug where the stdout_syslog and stderr_syslog options of a [program:x] section could not be used unless file logging for the same program had also been configured. The file and syslog options can now be used independently. Patch by Scott Stroupe.

• Fixed a bug where the logfile option in the [supervisord] section would not log to syslog when the special filename of syslog was supplied, as is supported by all other log filename options. Patch by Franck Cuny.

• Fixed a bug where environment variables defined in environment= in the [supervisord] section or a [program:x] section could not be used in %(ENV_x)s expansions. Patch by MythRen.

• The supervisorctl signal command now allows a signal to be sent when a process is in the STOPPING state. Patch by Mike Gould.

• supervisorctl and supervisord now print help when given -? in addition to the existing -h/--help.
