supervisor/HISTORY.txt

2.2b1 (2007-03-31)
------------------

- Individual program configuration sections can now specify an
  environment.

- Added a 'version' command to supervisorctl.  This returns the
  version of the supervisor2 package which the remote supervisord
  process is using.

2.1 (2007-03-17)
----------------

- When supervisord was invoked more than once, and its configuration
  was set up to use a UNIX domain socket as the HTTP server, the
  socket file would be erased in error.  The symptom of this was
  that a subsequent invocation of supervisorctl could not find the
  socket file, so the process could not be controlled (it and all of
  its subprocesses would need to be killed by hand).

- Close subprocess file descriptors properly when a subprocess exits
  or otherwise dies.  This should result in fewer "too many open
  files to spawn foo" messages when supervisor is left up for long
  periods of time.

- When a process was not killable with a "normal" signal at shutdown
  time, too many "INFO: waiting for x to die" messages would be sent
  to the log until we ended up killing the process with a SIGKILL.
  Now a maximum of one every three seconds is sent up until SIGKILL
  time.  Thanks to Ian Bicking.

- Add an assertion: we never want to try to marshal None to XML-RPC
  callers.  Issue 223 in the collector from vgatto indicates that
  somehow a supervisor XML-RPC method is returning None (which
  should never happen), but I cannot identify how.  Maybe the
  assertion will give us more clues if it happens again.

- Supervisor would crash when run under Python 2.5 because the
  xmlrpclib.Transport class in Python 2.5 changed in a
  backward-incompatible way.  Thanks to Eric Westra for the bug
  report and a fix.

- Tests now pass under Python 2.5.

- Better supervisorctl reporting on stop requests that have a FAILED
  status.

- Removed duplicated code (readLog/readMainLog), thanks to Mike
  Naberezny.

- Added tailProcessLog command to the XML-RPC API.  It provides a
  more efficient way to tail logs than readProcessLog().  Use
  readProcessLog() to read chunks and tailProcessLog() to tail.
  (thanks to Mike Naberezny).

2.1b1 (2006-08-30)
------------------

- "supervisord -h" and "supervisorctl -h" did not work (traceback
  instead of showing help view (thanks to Damjan from Macedonia for
  the bug report).

- Processes which started successfully after failing to start
  initially are no longer reported in BACKOFF state once they are
  started successfully (thanks to Damjan from Macdonia for the bug
  report).

- Add new 'maintail' command to supervisorctl shell, which allows
  you to tail the 'main' supervisor log.  This uses a new
  readMainLog xmlrpc API.

- Various process-state-transition related changes, all internal.
  README.txt updated with new state transition map.

- startProcess and startAllProcesses xmlrpc APIs changed: instead of
  accepting a timeout integer, these accept a wait boolean (timeout
  is implied by process' "startsecs" configuration).  If wait is
  False, do not wait for startsecs.

Known issues:

- Code does not match state transition map.  Processes which are
  configured as autorestarting which start "successfully" but
  subsequently die after 'startsecs' go through the transitions
  RUNNING -> BACKOFF -> STARTING instead of the correct transitions
  RUNNING -> EXITED -> STARTING.  This has no real negative effect,
  but should be fixed for correctness.

2.0 (2006-08-30)
----------------

- pidfile written in daemon mode had incorrect pid.

- supervisorctl: tail (non -f) did not pass through proper error
  messages when supplied by the server.

- Log signal name used to kill processes at debug level.

- supervisorctl "tail -f" didn't work with supervisorctl sections
  configured with an absolute unix:// URL

- New "environment" config file option allows you to add environment
  variable values to supervisord environment from config file.

2.0b1 (2006-07-12)
------------------

- fundamental rewrite based on 1.0.6, use distutils (only) for
  installation, use ConfigParser rather than ZConfig, use HTTP for
  wire protocol, web interface, less lies in supervisorctl.
