pyperl-1.0.1 compile error
by jbr＠FIZ-Karlsruhe.DE 12 Jun '03

12 Jun '03

Hello, I have tried to compile package pyperl-1.0.1.tar.gz on solaris. I am using gcc version 3.2 on solaris 5.8 and Python 2.1.3 (#1, Jun 4 2003, 16:09:53) Compilation of module perlxsi.c failed. With gcc 2.95 on a different maschine I got no warnings and could compile. Because I have to use gcc 3.2 (or sun cc ) on that machine, what can I do ?

Problem with calling methods
by Nikel, Ernst-Dieter 12 Jun '03

12 Jun '03

Hi everyone, I have the following problem: For example consider the code: <dtml-in "test.ba.objectValues()"> <dtml-var id> </dtml-in> This gives the ids in the folder test/ba. My problem is that in my applcation I get the path like "test/ba" in the example through a REQUEST. The script <dtml-in "_[tt].ba.objectValues()"> <dtml-var id> </dtml-in> works if the variable "tt" contains the value "test". But I don't have found a possibility to call the method if the given path (or better the relevant part of the path) contains more than one folder. The code <dtml-in "_[tt].objectValues()"> <dtml-var id> </dtml-in> don't works if the variable "tt" contains "test.ba". Thank you in advance for your help. Regards Ernst-Dieter

Re: [Zope] ZSQLMethodFile?

Version objects and created object bug
by J C Lawrence 12 Jun '03

12 Jun '03

Version objects seem to have some bugs related to objects created inside the version (newly created objects, not edited objects). As a simple example: 1) Create a folder, "test". 2) Create a version object in the folder. 3) Join/open the version. 4) Create two DTML documents in the root of the site, "test_aq". Note that it is controlled by the version (see the red star in the ZMI). Why? Shouldn't version objects apply only to their current folder and things under them, or are they really just named change sets for the entire Zope tree? Version objects ignore acquisition? 5) Create two DTML documents in "test", "unchanged" and "changed". 6) Make a simple edit to "changed" and save it. 7) Commit/save the version (you can quit the version first or not). 8) Quit the version if you haven't already. 9) View the "test" folder. Note that "changed" and "unchanged" are not visible outside of the version. (They should be!) 10) Join the version and note that "changed" and "unchanged" are still flagged as controlled by the version. What gives? In trying to dig thru this I ran into FileStorage:versionEmpty() (its in the call tree under the DTML that decides if there are things to commit in a version). I've been beating on that code for a few hours now and just don't grok it. Just what is the following condition testing for? if index[oid]==srcpos: return 0 Line 1384 for Zope 2.6.1. Or more simply, I don't understand what the following leading comment actually means: # When committing or aborting, we search backward through the linked # list until we find a record for an object that does not have a # current record in the version. If we find a record for which the # non-version pointer is the same as the previous pointer, then we # forget that the corresponding object had a current record in the # version. This strategy allows us to avoid searching backward # through previously committed or aborted version records. That comment would seem to suggest that the above conditional should be "!="?

Using tal and no dmtl.
by John Kipling Lewis 12 Jun '03

12 Jun '03

We are trying to use only TAL in our Zope documents. It's been frustrating in some ways. Is there a way in TAL to simply run a python function? We've been using the omit-tag to do this, but I find this cludgy. <div tal:omit-tag="python:foo()"></div> Are other people just using dmtl for this sort of thing. Is there a way to do it in TAL that isn't cludgy? John -

A few newbie questions
by Guillaume Dargaud 11 Jun '03

11 Jun '03

Okay, just getting started, so I have some pretty basic questions that have probably been answered plenty of times. 1) Where can I search the list archive ? 2) Where are the standard_html_header and standard_html_footer files ? I can't seem to find them under the root hierarchy. 3) I tried to play with the lesson8 in Elvis tutorial after reading chapter 3 of the Zope book where it references "class Image" in appendix B. So I changed the code like the AppB example: <dtml-var standard_html_header> <h2><dtml-var title></h2> <dtml-in expr="photoArchive.objectValues()"> <p> <dtml-var ImageObject> <P><dtml-var title> (<dtml-var getSize> bytes)</p> </dtml-in> <dtml-var standard_html_footer> But I get a Error Type: KeyError; Error Value: ImageObject when I try to view the results. What's missing ?!? 4) Is there a way to read the EXIF data off jpeg files directly from Zope ? Or the information data off png files ? I have plenty more questions but am too confused at this point to put them in meaningful sentances... -- Guillaume Dargaud Colorado State University - Dept of Atmospheric Science http://www.gdargaud.net/ "If it's not on fire, it's a software problem."

Problems with CookieCrumbler and ExternalEditor
by Andreas Pakulat 11 Jun '03

11 Jun '03

Hi, I seem to have a problem with CookieCrumbler and ExternalEditor. I installed both and they work. I installed a cookiecumbler into the Rootfolder, now I see the login_form of my Website whenever I access the /manage URL. While that's not a problem in the first place, it makes using ExternalEditor impossible, as the DAVLock is not done. If I remove the cookieauthentication Object, Logout and Login using HTTP-Auth I can use ExternalEditor again. If I then recreate the cookie_authentication and logout I'm not really logged out (free access to /manage). But restarting the Browser helps and the I log in using the websites login_form and clicking on a ExternalEdit Link I get a 401 Unauthorized Access Message from the ExternalEditor. Is there a possibility to use both together? Andreas -- You have many friends and very few living enemies.
