small edit textarea
by Jason B 03 May '00

03 May '00

I sure wish we could get a bigger area for the edit textarea box. If we could get rid of the "Size" and "Last Modified fields in the management screens we would have more room. Does anyone know where to make these changes? Maybe these fields shouldn't go away, maybe they should be placed along side the id and title? Also, the timestamp on a change goes underneath the status message of "Content Changed" - maybe this could go to the right of the message. It's not like that date is very important anyway, you can still see the "Last modified" date on the same return screen. If these little changes were made we could probably squeeze in 4 or 5 more lines of the edit textarea and not have to scroll as much. Sure would make editing easier. Another thing that I think would be cool would be to make the first slash in the links back through the tree a link to the root folder. What do you think? __________________________________________________ Do You Yahoo!? Talk to your friends online and get email alerts with Yahoo! Messenger. http://im.yahoo.com/

wget to manage zope - manage_restart
by Gustin Kiffney 03 May '00

03 May '00

I've got zope running on an intranet NT server and its ODBC connection keeps a number of database files open at all times which my backup system can't handle. Hitting the zope control panel restart button closes those files long enough to get them backed up, but I'd like to do this later at night and automatically because the files get opened again as soon as someone hits the site (all the picklists, etc come out of the ODBC database files). So far I can't figure out how to do this. It looks like just hitting the URL http://superuser:password@myserver/Control_Panel/manage_restart? should work (I'm using wget on a linux box to do this) should work, and it DOES work from IE, but it doesn't work from wget - here's what happens with wget doing this with that exact same url: I guess wget tries without authorization first: Server: Zope/Zope 2.1.4 (binary release, python 1.5.2, win32-x86) ZServer/1.1b1 Date: Thu, 27 Apr 2000 20:47:13 GMT Www-Authenticate: basic realm="Zope" Bobo-Exception-File: C:\PROGRA~1\WEBSITE3\lib\python\ZPublisher\HTTPResponse.py Bobo-Exception-Type: Unauthorized Content-Type: text/html Connection: close Bobo-Exception-Value: You are not authorized to access this resource.</s trong> Content-Length: 1376 Bobo-Exception-Line: 551 then wget says this: Closing fd 4 Connecting to 128.1.1.200:8080...

Anybody see what I'm doing wrong here?

Please help. On the top of 'index_html' I have: <dtml-if "REQUEST.has_key('SUBMIT')"> // this is the submit button of the form // the action of the form is 'index_html' itself <dtml-call insertNewItem> // this is a ZSQL method </dtml-if> -here is the form- The point is that I want the method to be executed only when the form is submitted. When first displayed nothing unusual happens (the REQUEST doesn't have 'SUBMIT'). But when I submit the form than this is what I get: Error Type: ValueError Error Value: Invalid Header (0): Does anyone know what is wrong with this (or with Zope)?

ZOPE Benchmark
by Ostermeyer＠t-online.de 03 May '00

03 May '00

BZ's ZOPE vrs Tomcat benchmarking reminds on another thing I'd noticed before, but didn't investigate any further: At that time I was playing around a little with Servlets. I'd run an file upload servlet with Jigsaw's Servlet Engine. (Jigsaw is another HTTP-Server written in Java. It's available for free on the W3C's web site.) I used the com.oreilly.servlet package to implement the servlet. It turned out, that uploading a 3.5 MB binary file by the servlet took about 42 seconds. Using ZOPE to upload the same file took about 17 seconds on the same machine. This is of course far from a real benchmark. But the results are stable and seem to proof BZ's scores. I don't know if this shows ZOPE's superior implementation over other (Java) web servers. My opinion is, that it must have something to do with the performance of Java and Python byte code, right? Have anybody a comparison of that kind? Andreas Ostermeyer

DTML and JavaScript
by a.wacknitz＠francotyp.com 03 May '00

03 May '00

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have some listboxes that depend on each other such that if an entry is selected in one of them the contents (filled by ZSQL scripts) of the others change. I assume that this is not possible with DTML solely. Therefore I consider JavaScript. But I have no experience with it and I ask myself if (and how) it is possible to mix DTML and JavaScript eg. using the onChange() event. Is there any documentation or examples on this theme that I can have a look at?

Re: [Zope] Problem calling manage_addZClass from DTML

Unless you are attempting somthing like the "local products" hack discussed here back in February (Products declared/scoped within "normal" Zope folders, rather than the "magic" Control_Panel/Products folder), I can't think of any reason you'd want to call "manage_addZClass" -- that method is designed to create the actual class object for a ZClass, and should normally only happen inside Control_Panel/Products. Instances of a given ZClass are created via the factory methods defined within the ZClass product. Guessing that you have defined a ZClass (lets say, "Guiness", defined within a Product called "HarpBrewery"), and want to instantiate it into a folder ("SeansMug"). The "factory methods" for the Guiness class are called Guiness_addForm (HTML form, collects the "constructor parameters") and Guiness_add (DTML method, extracts ctor parms from the REQUEST and creates the object. In this case, you could do the following within a DTML method bound to SeansMug (this assumes that the REQUEST object has previously been populated with appropriate values):: <dtml-with "manage_addProduct[ 'HarpBrewery' ]"> <dtml-call "Guiness.createInObjectManager( REQUEST[ 'ObjectName' ] , REQUEST )"> </dtml-with> Hope that helps!

This code is legacy code from ZTables, I didn't write it and I also didn't take it out, it's kinda like your appendix, you don't use it but it's there. In the future, indexes may store positional information. > All these bugs leaves me wondering if the catch all used in > _indexedSearch is necessary.

This method is also a carry over from ZTables. > Another question I have about ZCatalog is the following: Is ZCatalog > usable for searching and indexing gigabytes text? That's a hard question to answer. The short answer is yes. Over time, if you index your content incrementally, then you can easily text index gigabytes of text. If you were to try to feed gigabytes of text into Zope all in one shot, it would probably fail either due to: 1) not enough memory (no subtransations) 2) not enough tmp storage (with subtransactions) Since Zope is transactional, all changes are accumlated before commit. Because this commit happens 'all at once' for all objects a commit on gigabytes of objects *plus* indexes for them would take hours, days maybe. This is not a good way to do it. The best way index content is gradually, over time. We call this 'incremental' indexing. Using this slow scheme you could easily index gigabytes of text. -Michel

Properties disappearing inside <dtml-with>
by Mike Orr 02 May '00

02 May '00

I have a bunch of DTML Documents that call a group_html_footer (DTML Method) before standard_html_footer. Inside this method I need access to "title" (the document title) and "state" (a property in the document). I also need access to the images inside a "glue_images" folder. (The folder contains two images -- "glue_hr" and "gluemem" -- and nothing else.) Inside the method I have a <dtml-with glue_images> ... </dtml-with glue_images> block to pick up the images. For some reason, "title" and "state" are empty inside the block but are fine outside. I thought this was only supposed to happen with the "only" attribute. The following test code illustrates it. My state is <dtml-var state> My title is <dtml-var title> <dtml-with glue_images> My state is <dtml-var state> My title is <dtml-var title> ... REST OF METHOD </dtml-with glue_images> Results in: My state is CO My title is Colorado My state is My title is As a workaround, I turned the dtml-with to <dtml-let gluehr="glue_images.gluehr"> ... </dtml-let> This fortunately does not hide the other variables. Why is dtml-with eating my variables? -- -Mike Orr, mso(a)mso.oz.net -or- mso(a)oz.net (permanent: mso(a)jimpick.com) http://mso.oz.net/ English * Esperanto * Russkiy * Deutsch * Espan~ol

EOFError: end of stream during parse (Gadfly? SQLSession? Sybase?)
by Hung Jung Lu 02 May '00

02 May '00

Hi, I am getting this error quite often: Error Type: EOFError Error Value: end of stream during parse near :: "urOBv9CS7Mzi0g'"*"\012AND name = 'fi" I suspect that it is coming from Gadfly with SQLSession, but it could also be coming from Sybase. This happens randomly (so it's hard to repreduce) and goes away with a click on the Refresh button. Has anyone seen something similar? Any idea how to debug it? regards, Hung Jung ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
