own products over FTP
by Petr Knapek 07 Feb '01

07 Feb '01

Hi Zopists, I have created some python products for Zope and now I would like to have the possibility to create their instances in ZODB over FTP. Please give me a tip for documentation on this one. Help is also welcomed. Zope: 2.1.6 OS: Linux Debian Thank you, Petr -- Petr Knápek NEXTRA Czech Republic, s.r.o., Hlinky 114, 603 00 Brno, Czech Republic e-mail: mailto:petr.knapek@nextra.cz tel:+420-5-43 554 150 FAX:+420-5-43 554 214

SearchIndex / Lexicon bug
by richard＠bizarsoftware.com.au 07 Feb '01

07 Feb '01

I just submitted a bug report to the collector, and didn't supply a patch. I really should have, and here it is. *** /tmp/Lexicon.py Wed Feb 7 17:09:20 2001 --- lib/python/SearchIndex/Lexicon.py Wed Feb 7 17:09:32 2001 *************** *** 158,164 **** def get(self, key, default=None): """Return the matched word against the key.""" ! return [self._lexicon.getWordId(key, default)] def __getitem__(self, key): --- 158,164 ---- def get(self, key, default=None): """Return the matched word against the key.""" ! return [self._lexicon.get(key, default)] def __getitem__(self, key): I won't supply a patch for the other bug reported - ZCatalog/Catalog.py being to munchy with the exceptions - because I'm not entirely sure what the original purpose of the try/except clause is. As I mentioned in the bug report, I'm pretty sure it wasn't supposed to catch AttributeErrors. It's no longer in our code at all, and I'll let you know if that causes problems...

zope and java
by Mike Blake 07 Feb '01

07 Feb '01

Hi all, We're considering zope as a front-end publishing and web-app development solution for a project which has already developed a complex underlying layer of servlets for secure client/server transactions against their "host". Since we haven't been able to find any add-on products for zope providing an interface to java environments, we thought we'd ask: Can zope work wtih Java yet? If so, please point us in the right direction. Thanks, Mike Blake -- [morcilla(a)ketden.com chikoon]$ whoami ------------------------------------------------------------ [whoami] >> Mike Blake >> Web Developer / CellNetwork, Spain [e-mail] >> mike.blake(a)cellnetwork.com [icq] >> 103631268 [mobile] >> 678 642 392 [direct office phone] >> 91 761 4913 [office] >> Plaza Alonso Martinez 3, 4ª Planta, 28004 Madrid ------------------------------------------------------------

Mike asked: > Can zope work with Java yet? If so, please point us in the right direction. Phil responded: > I'll recap. There is a piece of software under development called JPE. > This is supposedly going to be or even is a Jave-Python gateway in effect. > > It should allow you to use Java classes in Python and Vice-versa. FYI, more details here: http://www.arakne.com/jpe.htm The actual interface seems to be based on JNI, which should be cross-platform, at least that's the intention. Discalimer: After you hit the link above you will know as much as I do. Later, Jerry S.

The field converters (:int, :text, etc.)
by Morten W. Petersen 06 Feb '01

06 Feb '01

Hi guys, IIRC, there was some talk about modularizing the field converters (checkers) so that they could be easiliy modified and added to. Is there currently any efforts to solving this problem? If not, there's definently a need for it, IMO.. Thank you for your time. -Morten

by Steve Alexander 06 Feb '01

The Zope 2.3 CVS has had the file main.dtml updated to fix problems with objects that don't do "get_size" properly (collector #1900). I've updated the following files from PlugIns accordingly. lib/python/Products/PlugIns/www/PlugInGroup.dtml lib/python/Products/PlugIns/www/main.dtml You can find copies here: http://www.cat-box.net/steve/PlugInGroup.dtml http://www.cat-box.net/steve/main.dtml -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

CoreSessionTracking stuff
by Andy McKay 05 Feb '01

05 Feb '01

More questions on CoreSessionTracking. On on site I wish to persist the information on a session indefinitely so a user can reconnect with those previous session settings. I looked at "External Session Data Container" (ESDC) and had some questions here I go: - Why does an ESDC have a session timeout in 20 minutes, yet the cookie lifespan can be 30 days. Surely there will be no way to tie a cookie back up to a session since the ESDC will be have had that person nuked, I was sort of hoping I coudl persist the data in the ESDC for a long time to provide storage (I could always set the minutes to 99999 or something silly). I guess if I really want data to be persisted for ever some sort of Membership product will be needed... - Mounting a non-undoable db into Zope is not trivial unless there is something Im missing. There's a non-undoable system every Zope installation has called the file system, why dont we use that? I was thinking we could modifiy LocalFS to provide that sort of functionality would be much easier... Cheers. -- Andy McKay.

Bug or feature (Zope Factory)
by Andreas Heckel 05 Feb '01

05 Feb '01

When I create a ZClass within a product called ZFooClass and I change the 'Add list name' property within it's ZFooClass_factory to 'Z Foo Class' no instance of this class can be pasted. The object [ZFooClass instance] does not support this operation Traceback (innermost last): File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/Zope/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/Zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_pasteObjects) File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_pasteObjects) File /usr/local/Zope/lib/python/OFS/CopySupport.py, line 199, in manage_pasteObjects (Object: ElementWithAttributes) File /usr/local/Zope/lib/python/OFS/CopySupport.py, line 377, in _verifyObjectPaste (Object: ElementWithAttributes) Copy Error: (see above) This is a Zope2.1.6 Traceback ... same behavior on 2.2.4 / 2.2.5 If I leave it 'ZFooClass' I can copy and paste instances. Do I miss something ? BTW: What's wrong with zope(a)zope.org? Although I can post at this time with on mail delivary warning I get no new messages ? -- _______________________________________________________________________ Andreas Heckel andreas(a)easyleading.org LINUX is like a wigwam...no gates...no windows and an apache inside ;-)
