Project Description

Pyst consists of a set of interfaces and libraries to allow programming of Asterisk from python. The library currently supports AGI, AMI, and the parsing of Asterisk configuration files. The library also includes debugging facilities for AGI.

Download from Sourceforge project page.

Installation is the standard python install:

tar xvf pyst.tar.gz
cd pyst
python setup.py install --prefix=/usr/local

Documentation is currently only in python docstrings, you can use pythons built-in help facility:

import asterisk
help (asterisk)
import asterisk.agi
help (asterisk.agi)
import asterisk.manager
help (asterisk.manager)
import asterisk.config
help (asterisk.config)

Some notes on platforms: We now specify “platforms = ‘Any’” in setup.py. This means, the manager part of the package will probably run on any platform. The agi scripts on the other hand are called directly on the host where Asterisk is running. Since Asterisk doesn’t run on windows platforms (and probably never will) the agi part of the package can only be run on Asterisk platforms.

Note

This project has been forked because it was impossible for me to contact the project maintainer (after several attempts), and I’d like to bring the project up-to-date, fix bugs, and make it more usable overall.

My plans immediate plans include adding full documentation, re-writing some of the core routines, adding a test suite, and accepting pull requests.

If you are one of the current maintainers, and would like to take over the fork, please contact me: rdegges@gmail.com, so we can get that setup!

Credits

Thanks to Karl Putland for writing the original package. Thanks to Matthew Nicholson for maintaining the package for some years and for handing over maintenance when he was no longer interested.

Things to do for pyst

This is the original changelog merged into the readme file. I’m not so sure I really want to change all these things (in particular the threaded implementation looks good to me). I will maintain a section summarizing the changes in this README, the ChangeLog won’t be maintained any longer. Detailed changes will be available in the version control tool (currently svn).

  • ChangeLog: The ChangeLog needs to be updated from the monotone logs.

  • Documentation: All of pyst’s inline documentation needs to be updated.

  • manager.py: This should be converted to be single threaded. Also there is a race condition when a user calls manager.logoff() followed by manager.close(). The close() function may still call logoff again if the socket thread has not yet cleared the _connected flag.

    A class should be made for each manager action rather than having a function in a manager class. The manager class should be adapted to have a send method that know the general format of the classes.

Matthew Nicholson writes on the mailinglist (note that I’m not sure I’ll do this, I’m currently satisfied with the threaded implementation):

For pyst 0.3 I am planning to clean up the manager.py. There are several know issues with the code. No one has actually reported these as problems, but I have personally had trouble with these. Currently manager.py runs in several threads, the main program thread, a thread to read from the network, and an event distribution thread. This causes problems with non thread safe code such as the MySQLdb libraries. This design also causes problems when an event handler throws an exception that causes the event processing thread to terminate.

The second problem is with the way actions are sent. Each action has a specific function associated with it in the manager object that takes all possible arguments that may ever be passed to that action. This makes the api somewhat rigid and the Manager object cluttered.

To solve these problems I am basically going to copy the design of my Astxx manager library (written in c++) and make it more python like. Each action will be a different object with certain methods to handle various tasks, with one function in the actual Manager class to send the action. This will make the Manager class much smaller and much more flexible. The current code will be consolidated into a single threaded design with hooks to have the library process events and such. These hooks will be called from the host application’s main loop.

Upgrading from older versions

If upgrading from…

  • 0.2:

    • get_header() methods in manager.py now work like dict.get() instead of dict[key]
  • 0.1.0:

    • agi.get_variable no longer throws an exception, instead it returns an empty string when a channel variable is not set.
    • manager.quit() has be renamed to manager.close()

Source Code Repository Access

The current versions are kept in a Subversion repository on Sourceforge. You can check out the trunk with:

svn co https://pyst.svn.sourceforge.net/svnroot/pyst/pyst/trunk pyst

There is also a 0.2 branch in:

https://pyst.svn.sourceforge.net/svnroot/pyst/pyst/branches/0.2

which contains unreleased changes after 0.2 (which have been merged into trunk after changing how manager commands to asterisk are parsed).

Released versions are in:

https://pyst.svn.sourceforge.net/svnroot/pyst/pyst/tags

For versions prior to the 0.2 release when Matthew Nicholson was maintaining pyst, the changes are kept in a monotone repository (monotone is a free distributed version control system). Please contact Matthew via Sourceforge if you’re interested in intermediate versions.

prior to that the sources are in the CVS repository on sourceforge.

Changes

Version 0.3: Minor feature enhancements

New maintainer Ralf Schlatterbeck, this is my first release, please report any problems via the Sourceforge Bug-Tracker or email me directly. Thanks to Karl Putland for writing the original package. Thanks to Matthew Nicholson for maintaining the package for some years and for handing over maintenance when he was no longer interested. The parsing of answers from asterisk was completely rewritten. This should fix problems people were having with commands returning embedded ‘/’ or empty lines. Some new manager commands added.

  • Add playdtmf manager command
  • add sippeers and sipshowpeer manager commands
  • rewritten manager communication
  • should no longer choke on ‘/’ in answers returned from a manager command (fixes SF Bug 2947866)
  • should now correctly parse multi-line output with embedded empty lines, e.g. mgr.command('dialplan show')
  • Bug-fix for list manipulation in event_dispatch, thanks to Jan Mueller, see mailinglist comment from 2008-04-18
  • Merge unreleased changes from repository of Matthew Nicholson in particular a typo in agi.py for set_autohangup, and change of get_header methods (see Upgrading instructions). The fixed manager.command support is already in (with a different solution). The unreleased changes are also on the 0.2 branch in the subversion repository in case somebody is interested.

See the ChangeLog for older changes.
