While doing some work for the caching mechanism in the XpTrackerPlugin, I found that I need to do some procesing after the topic was saved.

I patched the TWiki20031218beta version files StoreDotPm and PluginsDotPm to add an afterSaveHandler that can be used by plugins for after-save processing the topic.

Please see MorePluginHooks. I suggested an afterSaveHandler plugin hook myself months ago, because I needed it for ImmediateNotifyPlugin. My implementation of the handler against BeijingRelease is available in the plugin topic. I think this handler will make it into the plugin API for CairoRelease. I'll have to look at your version and see whether your implementation is compatible with mine. If not, we'll have to figure out one that satisfies the needs of both plugins (and any future plugins that might want to use this handler), preferably before the CairoRelease plugin API is fixed.

Thanksfully we both named the handler the same way and put it in the same place. The only difference seems to be that your version requires an additional parameter ($error).

I have made a patch against the TWikiAlphaRelease tagged TWiki20040229alpha, I'll update the patch to the TWiki20040301alpha version and change this topic into a PatchProposal as soon as I test it with your plugin.

The unified patch against the TWikiAlphaRelease tagged TWiki20040301alpha is up. I think that the differences between my version and Walter implementation, but couldn't test the ImmediateNotifyPlugin

I'm changing this into a PatchProposal

-- RafaelAlvarez - 04 Mar 2004

Alright, great. As soon as I have time to test it out a bit and make whatever minor changes may be necessary I'll get this into the core.

Committed to CVS. Note that I've added actually passing the error through to the plugin in Store and removed the comments with your name. (We do appreciate those comments being there, but since they generally are there to identify "unofficial" patches having been applied to a TWiki installation they don't often get committed to CVS.)

-- WalterMundt - 07 Mar 2004

I finished the incomplete implementation: Added the handler to DefaultPlugin and EmptyPlugin; added meta data to text of afterSaveHandler (othogonal to beforeSaveHandler). Change is in TWikiAlphaRelease and at TWiki.org.

Thanks Peter, that is really useful.

Martin - you need to document the parameters and returns for these 2 functions. -- SvenDowideit - 19 Jul 2004
