  • Add support for Python 3.4.

  • zdaemon can now be invoked as a module as in python -m zdaemon ...

4.0.0 (2013-05-10)

  • Add tox support and MANIFEST.in for proper releasing.
  • Add Python 3.3 support.
  • Drop Python 2.4 and 2.5 support.

3.0.5 (2012-11-27)

  • Fixed: the status command didn't return a non-zero exit status when the program wasn't running. This made it impossible for other software (e.g. Puppet) to tell if a process was running.

3.0.4 (2012-07-30)

  • Fixed: The start command exited with a zero exit status even when the program being started failed to start (or exited imediately).

3.0.3 (2012-07-10)

  • Fixed: programs started with zdaemon couldn't, themselves, invoke zdaemon.

3.0.2 (2012-07-10)

Fail :(

3.0.1 (2012-06-08)

  • Fixed:

    The change in 2.0.6 to set a user's supplemental groups broke common configurations in which the effective user was set via su or sudo -u prior to invoking zdaemon.

    Now, zdaemon doesn't set groups or the effective user if the effective user is already set to the configured user.

3.0.0 (2012-06-08)

  • Added an option, start-test-program to supply a test command to test whether the program managed by zdaemon is up and operational, rather than just running. When starting a program, the start command doesn't return until the test passes. You could, for example, use this to wait until a web server is actually accepting connections.

  • Added a start-timeout option to error if a program takes too long to start. This is especially useful in combination with the start-test-program option.

  • Added an option, stop-timeout, to control how long to wait for a graceful shutdown.

    Previously, this was controlled by backoff-limit, which didn't make much sense.

  • Several undocumented, untested, and presumably unused features were removed.

2.0.6 (2012-06-07)

  • Fixed: When the user option was used to run as a particular user, supplemental groups weren't set to the user's supplemental groups.

2.0.5 (2012-06-07)

(Accidental release. Please ignore.)

2.0.4 (2009-04-20)

  • Version 2.0.3 broke support for relative paths to the socket (-s option and socket-name parameter), now relative paths work again as in version 2.0.2.
  • Fixed change log format, made table of contents nicer.
  • Fixed author's email address.
  • Removed zpkg stuff.

2.0.3 (2009-04-11)

  • Added support to bootstrap on Jython.
  • If the run directory does not exist it will be created. This allow to use /var/run/mydaemon as run directory when /var/run is a tmpfs (LP #318118).

Bugs Fixed

  • No longer uses a hard-coded file name (/tmp/demo.zdsock) in unit tests. This lets you run the tests on Python 2.4 and 2.5 simultaneously without spurious errors.
  • make -h work again for both runner and control scripts. Help is now taken from the __doc__ of the options class users by the zdaemon script being run.

2.0.2 (2008-04-05)

Bugs Fixed

  • Fixed backwards incompatible change in handling of environment option.

2.0.1 (2007-10-31)

Bugs Fixed

  • Fixed test renormalizer that did not work in certain cases where the environment was complex.

2.0.0 (2007-07-19)

  • Final release for 2.0.0.

2.0a6 (2007-01-11)

Bugs Fixed

  • When the user option was used, it only affected running the daemon.

2.0a3, 2.0a4, 2.0a5 (2007-01-10)

Bugs Fixed

  • The new (2.0) mechanism used by zdaemon to start the daemon manager broke some applications that extended zdaemon.
  • Added extra checks to deal with programs that extend zdaemon and copy the schema and thus don't see updates to the ZConfig schema.

2.0a2 (2007-01-10)

New Features

  • Added support for setting environment variables in the configuration file. This is useful when zdaemon is used to run programs that need environment variables set (e.g. LD_LIBRARY_PATH).
  • Added a command to rotate the transcript log.

2.0a1 (2006-12-21)

Bugs Fixed

  • In non-daemon mode, start hung, producing annoying dots when the program exited.
  • The start command hung producing annoying dots if the daemon failed to start.
  • foreground and start had different semantics because one used os.system and another used os.spawn

New Features

  • Documentation
  • Command-line arguments can now be supplied to the start and foreground (fg) commands
  • zdctl now invokes itself to run zdrun. This means that it's no-longer necessary to generate a separate zdrun script. This especially when the magic techniques to find and run zdrun using directory sniffing fail to set the path correctly.
  • The daemon mode is now enabled by default. To get non-daemon mode, you have to use a configuration file and set daemon to off there. The old -d option is kept for backward compatibility, but is a no-op.

1.4a1 (2005-11-21)

  • Fixed a bug in the distribution setup file.

1.4a1 (2005-11-05)

  • First semi-formal release.

After some unknown release(???)

  • Made 'zdaemon.zdoptions' not fail for --help when __main__.__doc__ is None.

After 1.1

  • Updated test 'testRunIgnoresParentSignals':
o Use 'mkdtemp' to create a temporary directory to hold the test socket
rather than creating the test socket in the test directory. Hopefully this will be more robust. Sometimes the test directory has a path so long that the test socket can't be created.
o Changed management of 'donothing.sh'. This script is now created by
the test in the temporarily directory with the necessary permissions. This is to avoids possible mangling of permissions leading to spurious test failures. It also avoids management of a file in the source tree, which is a bonus.

  • Rearranged source tree to conform to more usual zpkg-based layout:

    o Python package lives under 'src'.

    o Dependencies added to 'src' as 'svn:externals'.

    o Unit tests can now be run from a checkout.

  • Made umask-based test failures due to running as root emit a more forceful warning.

1.1 (2005-06-09)

  • SVN tag: svn://svn.zope.org/repos/main/zdaemon/tags/zdaemon-1.1
  • Tagged to make better 'svn:externals' linkage possible.
