Release History

v1.2.3 (2021-04-22)

  • Pass args to click from Daemon.cli()
  • Don't run start hook on reload or when the daemon is already running

v1.2.1 and v1.2.2 (2021-02-16)

  • Minor tweaks to some undocumented experimental features

v1.2.0 (2021-02-15)

  • Dropped support for Python 2.7 and 3.5 (only >= 3.6 is now supported)
  • Deprecated shutdown_callback argument in favor of new hooks system. Replace shutdown_callback=func with hooks={'shutdown': func}.
  • Added 'start' hook that gets called before attempting to start the daemon. This can be useful for checking things or setting things up.
  • Improvements to some undocumented experimental features. :)

v1.1.1 (2020-12-31)

  • The stop action will now clean up the PID file if the worker didn't do it for some reason.
  • A few bug fixes to some undocumented experimental features. :)

v1.1.0 (2020-12-16)

  • Official support for Python 3.9
  • Added back official support for Python 3.5
  • Increased test coverage to over 95%.
  • All tests now pass on macOS (Intel) and the GitHub Actions build now runs on macOS 10.15 in addition to Ubuntu.
  • Fixed the close_open_files option to be much more reliable and consistent across different platforms.
  • Fixed a race condition with the self-reload functionality where the PID file of the parent process was being deleted while the child process was trying to read it.
  • Added stdout_file and stderr_file arguments to Daemon. If these arguments are provided when detach=True, STDOUT and STDERR will be redirected to these files. In non-detached mode, these arguments are ignored.
  • When chrootdir is given, all other paths are now always considered relative to the chroot directory, even with a leading slash.
  • Actions can now take arbitrary arguments, and (on Python 3) CLI options are auto-generated from the function signature. The auto-generated CLI options work best when your action's function signature contains type annotations and default values where applicable.
  • Added timeout and force arguments to the built-in stop action, accessible from the CLI as --timeout and --force.
  • Added json and fields arguments to the built-in status action, accessible from the CLI as --json and --fields.
  • Added colored output when the output stream is attached to a terminal.
  • Fixed a bug where the daemon wouldn't respond properly to docker stop when running in a docker container.
  • The worker function can now be a method called worker on a Daemon subclass.
  • Some more secret experimental stuff. :)

v1.0.2 (2020-07-12)

  • Official support for Python 2.7, 3.6, 3.7, and 3.8.
  • Fixed bug checking if a stream is a socket on Python 3.8.
  • Closing open files is now more efficient on systems with a very high limit on the number of open files.
  • Improved detection of running inside a container.

v1.0.1 (2016-04-17)

  • No changes in this release. Bumped version only to re-upload to PyPI.

v1.0.0 (2016-04-17)

  • Added official support for Python 2.7, 3.3, 3.4, and 3.5.
  • Added a comprehensive suite of unit tests with over 90% code coverage.
  • Dependencies (click and psutil) are no longer pinned to specific versions.
  • Fixed bug with atexit handlers not being called in intermediate processes.
  • Fixed bug when PID file is a relative path.
  • Fixed bug when STDIN doesn't have a file descriptor number.
  • Fixed bug when running in non-detached mode in a Docker container.
  • A TTY is no longer checked for when deciding how to run in non-detached mode. The behavior was inconsistent across different platforms.
  • Fixed bug when a process stopped before having chance to check if it stopped.
  • Fixed bug where an exception could be raised if a PID file is already gone when trying to remove it.
  • Subdirectories created for PID files now respect the umask setting.
  • The pre-umask mode for PID files is now 0o666 instead of 0o777, which will result in a default mode of 0o644 instead of 0o755 when using the default umask of 0o22.

v0.8 (2014-08-01)

  • Upgraded click to version 2.5.
  • Status action now returns exit code 1 if the daemon is not running.

v0.7 (2014-06-23)

  • Fixed bug that was causing an empty PID file on Python 3.
  • Upgraded click to version 2.1.
  • Open file discriptors are no longer closed by default. This functionality is now optional via the close_open_files argument to Daemon().
  • Added is_worker argument to DaemonCLI() as well as the pass_daemon decorator.

v0.6 (2014-06-10)

  • Upgraded click to version 2.0.

v0.5 (2014-06-09)

  • Fixed literal octal formatting to work with Python 3.

v0.4 (2014-05-19)

  • Fixed bug with uptime calculation in status action.
  • Upgraded click to version 0.7.

v0.3 (2014-05-14)

  • Reorganized package and cleaned up code.

v0.2 (2014-05-12)

  • Renamed Daemon.get_actions() to Daemon.list_actions().
  • Improvements to documentation.
  • Fixed bug with non-detached mode when parent is in the same process group.

v0.1 (2014-05-11)

  • Initial release.
