Helping Digital Creations fix bugs - suggestions

I just answered a question on the Zope list about a bug in Gadfly which doesn't allow linebreaks. I was at least the second person to encounter this bug - I got the answer from someone else. The solution is to delete 1(!) character. I submitted it to the Collector, and now it says: Submitted: 2000/01/11 * * * This item is under review * * * okay, there was a conference, and it's not so big a bug, but I get the feeling nobody ever read the bug report, since fixing it takes 30 seconds at the most. I doubt it'll be fixed until someone from DC find the bug independently. I know DC asked about this at the conference, but I think people who weren't there might think of something too. Some uggested solutions (from what DC promised/suggested or): 1. Hand out portions of Zope to outside people (stuff like load_site.py or StructuredText comes to mind). I'd volunteer for load_site (proof of competence will be presented once I check that my merge with CVS actually works :). and/or Setup a (moderated?) mailing-list for each component devoted only to that specific component and force ZComponent's maintainer to read it. I'm thinking zope-zcatalog and zope-sql and zope-zpublisher, modeled after the mozilla and ptk lists. How many patches sent to zope-dev or zope lists got lost in the all the noise? 2. Change Collector so it has categories for stuff like Gadfly, StructuredText - for every Zope component. Remove obsolete stuff like ZTables. If I file a Gadfly bug, it should be emailed to the ZGadflyDA maintainer. Switch to Roundabout (http://www.lfw.org/python) when it's released? Anybody else have suggestions? -- Itamar S.T. itamars(a)ibm.net

I've been thinking about that one, just in general, trying to figure out which of the many WTDI (ways to do it) works best -- I think I will add a thumb rule to my list of Zopeisms as follows: * Any use of "manage_*" methods from within Python (not PythonMethods, though -- they don't have access to the Right Stuff) is highly suspect, and signals a need to refactor somewhere. This includes just about any method which takes REQUEST or RESPONSE as explicit parameters. -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com

blah
by Terry Kerr 08 Feb '00

08 Feb '00

Hi, I setup an ZCatalog index "self._catalog.addIndex('description', 'TextIndex')". All the ZCatalog Aware objects have this description attrribute...which is just a string. Now when I go "<dtml-in "MyCatalog(description='blah')>" it should return all objects with 'blah' in the description attribute. But it is not! It is acting very strangly. It sometimes does after I do a reindex, but sometimes doesn't. My product inherits from ZCatatlog, and its default_catalog=self.id. Am I missing something? The fieldIndex's work fine. Is there some problem with the way lookups are done with TextIndex? I am using zope 2.1.3 from src. -- Terry Kerr (terry(a)adroitnet.com.au) Adroit Internet Solutions Pty Ltd (www.adroitnet.com.au) (03) 9888 8522 0414 938 124

Zope as a proxy - cache server

Can I use zope as a proxy / cache server? Does it require to make changes on the zserver code or just zclient is enough? Rgs, Kent Sin

Computed fields in ZCatalog
by Kevin Dangoor 07 Feb '00

07 Feb '00

Hi, Looking at the ZCatalog code, if an index or metadata field is callable for a particular object, then that function will be called. However, it isn't called with *any* parameters. Is there any way to make that metadata value based upon other values in the object? For example, if I wanted to create a method that would return Property1+Property2 and have that value show up in the Catalog, can that be done? Kevin

Scheduler product, anyone?
by Loren Stafford 07 Feb '00

07 Feb '00

At one time there was talk on this list (or zope(a)zope.org) of building a scheduler product -- something that would automatically execute specified methods at specified times or time intervals. Does anyone have such a product in the works? ...or is it time for me to roll up my sleeves and get to work? -- Thanks -- Loren

Database connections
by Stephan Richter 07 Feb '00

07 Feb '00

Hello everyone, My client went live with a site today and we are having huge problems with the DB connections. Every one out of five times the request will time out. We are heavily using DB tables for our data storage. (We are using PostGres.) My client has read that other people experienced the same issue, since only 7 DB connections are allowed at a given time. She read that you can hack the python code somewhere. I am sure you guys know how to do this. If you could send me a set of instructions of how to fix it, that would be great.

[PATCH] Improved Lynx managing experience
by Petru Paler 07 Feb '00

07 Feb '00

In the hope that I'm not the only one using Lynx with Zope often enough to get irritated by the double links in the Folder contents manage screen, I attach this patch. PS: usage info: save this message into a text file then cd into you Zope install dir and do a 'patch < file_name'. PPS: it does not affect in any way the management interface when used with any other browser than Lynx. text-ly yours, -Petru --- lib/python/OFS/main.dtml.org Mon Feb 7 15:24:18 2000 +++ lib/python/OFS/main.dtml Mon Feb 7 15:25:39 2000 @@ -16,7 +16,7 @@ <INPUT TYPE="CHECKBOX" NAME="ids:list" VALUE="<dtml-var sequence-key html_quote>"> </TD> <TD ALIGN="LEFT" VALIGN="TOP"> - <dtml-if icon> + <dtml-if "icon and _.string.find(HTTP_USER_AGENT, 'Lynx') == -1"> <A HREF="<dtml-var sequence-key url_quote>/manage_workspace"> <IMG SRC="<dtml-var SCRIPT_NAME>/<dtml-var icon>" ALT="[<dtml-var meta_type>]" BORDER="0"></A>

Expressions like <dtml-var this url> bail out contrary to intuition -- proposed fix enclosed
by Jarkko Kniivilä 07 Feb '00

07 Feb '00

Hi fellow Zopistas! While upgrading a Zope 2.1.0 beta installation recently to 2.1.3, I discovered that a recent change made to 'DT_Var.py' rendered DTML expressions like <dtml-var this url> and &dtml.url-this; inoperative. I had been relying on them for a default action url on my forms (in DTML methods). Especially the entity reference syntax is quite a nice abbreviation for the more explicit <dtml-var "this().absolute_url()"> which still continues to work. The enclosed fix simply acknowledges that 'this' isn't a ZODB namespace object but a method encapsulating python 'self' and thus always needs to be invoked. I'm not quite on the top of things why the previous behavior was changed in the first place (Jim? Anyone?). I'll file this to the Collector if there's no objection by you. Copyright to the patch is hereby transfered to Digital Creations to be used freely. Cheers, // Jarkko Kniivila, CTO, Ambient Factor New Media, Hameenlinna, Finland
