Feature Proposal: Background Tasking Framework

Motivation

As discussed in previous topics - here and in the fork - TWiki has no convenient way to do background processing. The current methods(e.g.tick_twiki.pl) are inflexible, do not support plugins and are not easy to manage.

The Tasking Framework solves these problems. It's been running as a prototype (Alpha quality) for over a year on my site.

Description and Documentation

This is a complex - but not particularly risky - package. It's in fairly good shape - except that the documentation needs to be extracted from the source modules (there's a tool for that) and organized into a wiki page(s). I need a volunteer for that.

Once it is merged into trunk, over time plugins will want to start using it. The most obvious usage (and the original motivation) is periodic removal of temporary files. But MailerContrib would benefit from scheduling, and the list of additional uses is endless.

Key features:

  • Simple interface for Plugins - add a driverCleanup routine, and it will be called on an admin-defined schedule. Easiest way to handle working directory cleanups
  • Scheduling uses crontab format, but a GUI (in configure) is provided to simplify use.
  • Tasks run by a daemon, which provides a persistent environment (for performance).
  • Full-featured API for more complex applications
    • Three calls added to Func namespace
    • Task API is OO; tasks can be scheduled, cancelled, modified, etc.
  • Auto-loaded "drivers" for contribs and other non-plugin extensions
  • Tasks can be triggered based on events as well as time. Events include:
    • File/directory modification/creation/deletion
    • Change to wiki configuration
  • Replaces tick_twiki.pl
  • Events provide parameters
  • Multiple execution queues allow parallel processing - with dependencies
  • External commands can also be scheduled.
  • Internal tasks inherit persistent environment, but execute in their own fork. Daemon communication is secured via RPC.
  • Generated output is logged, optionally mailed to administrator (like cron).
  • Debugging support.
  • Web-based management (including https:) of daemon
  • Full documentation is in source files (can can be extracted by supplied script); however, it needs to be organized into one or more wiki pages.
  • Examples and some debugging test cases provided.
  • Integrates with Configure - plugins and contribs simply provide files - culturally compatible for developers.
Included is an installation utility which handles setting up links and other minor headaches. More importantly, it provides a mechanism for painlessly packaging any kit (including the core) such that it can be installed with selinux contexts and permissions according to site policy. This mechanism uses structured comments to extend the MANIFEST format, and should be considered for all of TWiki. It would greatly simplify installation - no more hassles with every install resetting permissions and manual fixups.

Finally, the installer is designed to autosense TWiki v.s. the fork, and the Task Framework is intended to work in both environments. However, the code has not yet been ported to the other wiki - mostly Configure issues.

This has been developed/tested on linux (fedora). Windows has not been tested and probably needs some work. Other distributions should work, but need testing. It would not be surprising if some minor edits were required. A volunteer(s) would be appreciated.

I have been unable to make the time to wrap this up, but it is (and has been) ready for broader exposure.

Examples

Here is a sample of the management interface:

Impact

WhatDoesItAffect: API, Documentation, Install, Usability

No impact on traditional TWiki operation or software (except for replacing tick_twiki.pl).

Currrent packaging is in two tarballs, plus core changes:

Core support:

Configure support is in 5.1.0, although some (field width-related) bugs may still be pending. Peter?

Discussion

Sorry about some of the formatting; copy and paste of status confused the WYSIWYG editor, and the kit listings, which had pre tags were also corrupted by it. Since the result is still readable, I'm not going to fix it up. It would just be corrupted again by the next edit to this topic.

  • Feedback from JerusalemReleaseMeeting2012x09x14:
    • Proposal was missed because committed date and committed developer field where missing
    • Lengthy discussion on excellent proposal
    • Implementation finished in alpha
    • Needs more documentation, TWiki.TWikiTaskFramework topic is needed
    • This comes with install script, so needs some thought how to ship with TWiki that does not have/depend on install script
    • Possibly ship with core, disabled, with docs to run install script
    • Let's discuss for a few days in proposal topic
    • Ideally, Timothe would do check-in
    • PTh to install and test

I would say that the doc issue is that almost everything needed exists, but it's in sections scattered thru the code. Where I could use help (due to severe time limitations) is having someone mark the sections in some sensible order. Then a(n existing in the kit) tool knows how to extract them to be put into a wiki page.

Also, there was a lot of discussion when I started the project that may be useful. See the following links (I haven't visited in a while, but these are from my bookmarks.) http://twiki.org/cgi-bin/view/Codev/PluginGarbageCollection http://foswiki.org/Tasks/Item10780 http://foswiki.org/Development/PluginGarbageCollection http://foswiki.org/Development/PeriodicTasks

I appreciate the help and support.
