  • v1.0.6 Changes

    November 20, 2005
    • Various tweaks to make run more effectively on Mac OS X (including fixing tests to run there, no more "error reading from fd XXX" in logtail output, reduced disk/CPU usage as a result of not writing to log file unnecessarily on Mac OS).
  • v1.0.5 Changes

    July 29, 2004
    • ๐Ÿš€ Short description: In previous releases, managed programs that created voluminous stdout/stderr output could run more slowly than usual when invoked under supervisor, now they do not.

    Long description: The supervisord manages child output by polling pipes related to child process stderr/stdout. Polling operations are performed in the mainloop, which also performs a 'select' on the filedescriptor(s) related to client/server operations. In prior releases, the select timeout was set to 2 seconds. This release changes the timeout to 1/10th of a second in order to keep up with client stdout/stderr output.

    Gory description: On Linux, at least, there is a pipe buffer size fixed by the kernel of somewhere between 512 - 4096 bytes; when a child process writes enough data to fill the pipe buffer, it will block on further stdout/stderr output until supervisord comes along and clears out the buffer by reading bytes from the pipe within the mainloop. We now clear these buffers much more quickly than we did before due to the increased frequency of buffer reads in the mainloop; the timeout value of 1/10th of a second seems to be fast enough to clear out the buffers of child process pipes when managing programs on even a very fast system while still enabling the supervisord process to be in a sleeping state for most of the time.

  • v1.0.4 Changes

    June 30, 2004
    • โšก๏ธ Forgot to update version tag in configure.py, so the supervisor version in a3 is listed as "1.0.1", where it should be "1.0.3". a4 will be listed as "1.0.4'.

    • Instead of preventing a process from starting if setuid() can't be called (if supervisord is run as nonroot, for example), just log the error and proceed.

  • v1.0.3 Changes

    May 26, 2004
    • The daemon could chew up a lot of CPU time trying to select() on real files (I didn't know select() failed to block when a file is at EOF). Fixed by polling instead of using select().

    • ๐Ÿ–จ Processes could "leak" and become zombies due to a bug in reaping dead children.

    • 0๏ธโƒฃ supervisord now defaults to daemonizing itself.

    • 'daemon' config file option and -d/--daemon command-line option removed from supervisord acceptable options. In place of these options, we now have a 'nodaemon' config file option and a -n/--nodaemon command-line option.

    • logtail now works.

    • ๐Ÿ”€ pidproxy changed slightly to reap children synchronously.

    • in alpha2 changelist, supervisord was reported to have a "noauth" command-line option. This was not accurate. The way to turn off auth on the server is to disinclude the "passwdfile" config file option from the server config file. The client however does indeed still have a noauth option, which prevents it from ever attempting to send authentication credentials to servers.

    • ZPL license added for ZConfig to LICENSE.txt

  • v1.0.2 Changes

    • supervisorctl and supervisord no longer need to run on the same machine due to the addition of internet socket support.

    • ๐Ÿ”ง supervisorctl and supervisord no longer share a common configuration file format.

    • supervisorctl now uses a persistent connection to supervisord (as opposed to creating a fresh connection for each command).

    • ๐Ÿ‘ SRP (Secure Remote Password) authentication is now a supported form of access control for supervisord. In supervisorctl interactive mode, by default, users will be asked for credentials when attempting to talk to a supervisord that requires SRP authentication.

    • ๐Ÿ”ง supervisord has a new command-line option and configuration file option for specifying "noauth" mode, which signifies that it should not require authentication from clients.

    • ๐Ÿ”ง supervisorctl has a new command-line option and configuration option for specifying "noauth" mode, which signifies that it should never attempt to send authentication info to servers.

    • supervisorctl has new commands: open: opens a connection to a new supervisord; close: closes the current connection.

    • ๐ŸŒฒ supervisorctl's "logtail" command now retrieves log data from supervisord's log file remotely (as opposed to reading it directly from a common filesystem). It also no longer emulates "tail -f", it just returns lines of the server's log file.

    • The supervisord/supervisorctl wire protocol now has protocol versioning and is documented in "protocol.txt".

    • "configfile" command-line override -C changed to -c

    • top-level section name for supervisor schema changed to 'supervisord' from 'supervisor'

    • โž• Added 'pidproxy' shim program.

    Known issues in alpha 2:

    • If supervisorctl loses a connection to a supervisord or if the remote supervisord crashes or shuts down unexpectedly, it is possible that any supervisorctl talking to it will "hang" indefinitely waiting for data. Pressing Ctrl-C will allow you to restart supervisorctl.

    • Only one supervisorctl process may talk to a given supervisord process at a time. If two supervisorctl processes attempt to talk to the same supervisord process, one will "win" and the other will be disconnected.

    • Sometimes if a pidproxy is used to start a program, the pidproxy program itself will "leak".

  • v1.0.0 Changes

    ๐ŸŽ‰ Initial release.
