The code I've just about finished will do this, and it also only stores deltas between files (unless the md5 changes, or the file shrinks, in which case it writes a full file). I also plan to support gzipping the data files in the repository. Once this is done, I'll be running it 12-hourly here to allow us some recovery to any cases of screwups.

I could not even log in to the management-screen... Hmm... me thinks this has nothing to do then with the code in Publish.py, that file has been around for years and is extremly stable. If you can't log in the managment interface, the problem is probably something completely different. -Michel

All other index meta-data about your product should catalog normally. If your news items aren't showing up, it may be because no-one has approved it.

I'll check the 2.1.2 release, since the CVS is different than what you point out that probably means whatever problem you're having is fixed. -Michel

Is it a good sollution? Is the problem real, or in > my mind? You have identified a real problem: it is a pain even for me in a site where I stage projects for different clients. One solution I had considered was to hack the factories to add a "global_visibility" flag to them, and to add a "factory proxy" object which would be dropped into the main Zope tree which would "surface" its factory to folders which acquired it. + Zope + Control Panel + Products + FooProduct + FooClass + FooFactory (global_visibility not checked) ... + FolderUnderWhichIWantToEnableFooFactory o FooFactoryProxy + FolderWhichCanContainFoos FooNumberOne Another namespace problem I have it the pollution of the "Permissions" namespace (mentioned in another thread). Perhaps the "visibility" flag should be a property of the Product, and therefore apply to _all_ its objects: permissions, classes, factories, etc.? An alternative to the proxy object would be to add a view to the Folder which allowed filtering the Products which could be used beneath it. -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com

Aside from the inability to turn these back into Data.fs files, didn't someone mention at some point that the XML exports weren't properly formed XML? Or was it that there was no DTD for them? Having said that, IBM had some software for doing proper diffs of XML documents, so if it _was_ possible to export the root object (or, better yet, convert the on-disk ZODB file directly into XML, so that you get to keep the old versions &c around), it would be way cool.

mod_pcgi2 version 0.4.0
by Oleg Broytmann 12 Jan '00

12 Jan '00

Hello! http://www.zope.org/Members/phd/mod_pcgi2 - version 0.4.0. Fixed a minor problem with pcgiStartProc - changed it back to double-fork. This introduces problems for people who want to compile the module on Win32. I don't know how to help them; if anyone is interested in compiling the module on Win32 - patches accepted... The module finally seems pretty stable, all neccessary features implemented, all bugs caught and fixed. I thing this is last release before 1.0. BTW, it seems my news items do not appear on Zope front page. They stopped after I changed naming scheme from mod_pcgi2_v0.2.0 to mod_pcgi2-v0.3.0 (underscore to dash). It seems ZCatalog hates dashes, right? Oleg. ---- Oleg Broytmann http://www.fortunecity.com/skyscraper/unix/797/ phd2(a)email.com Programmers don't die, they just GOSUB without RETURN.
