(or misconfigured system) Probably in the FreeBSD library, because not only "Splitter.c" uses "char" for strings but almost all C modules I know of. Nevertheless, you patch to "splitter" should be welcome as it solves a usability problem on FreeBSD systems. Put it into the collector (URL:http://classic.zope.org/Collector) You may file a problem report to the FreeBSD maintainers in parallel. Dieter

Thus, for <dtml-if var1 and var2>, you should use: <dtml-if "(_.has_key('var1') and var1) and (_.has_key('var2') and var2)"> Dieter

manage_afterAdd - need enlightenment
by Aleksander Salwa 11 Sep '00

11 Sep '00

I decided to convert my ZClasses to CatalogAware. I added CatalogAware as first base class. If I add <dtml-call "index_object()"> in my MyZClass_add method, then new object is automatically indexed as expected. But in CatalogAwareness.py I see method manage_afterAdd, which does the same. Is this method called automatically (probably not), or have I to call it - where, what arguments ? I tried to call it after call to _add method - I got strange error: Error Type: AttributeError Error Value: _u This ZClass base classes are CatalogAware and DTMLDocument. Without mentioned call to "index_object", object is not indexed. I need some enlightenment on manage_afterAdd - how (and why) to use it, and CatalogAware in general :) Of course, I can put "index_object()" in every _add method, but probably it's not the right way of doing things. ololo(a)zeus.polsl.gliwice.pl /--------------------------------------\ | `long long long' is too long for GCC | \--------------------------------------/

ZGDChart/GDChart on Linux
by Hung Jung Lu 11 Sep '00

11 Sep '00

Hmmm... I don't remember anymore how to build GDChart on Linux. To simplify the situation, let us say that we want to focus on GDChart alone, not ZGDChart. I downloaded from http://athani.pair.com/msteed/software/gdchart/index.html and did the "make -f makepy.linux" thing. But when I opened a Python interpreter, it says: >>>import gdchart Traceback (innermost last): File "<stdin>", line 1, in ? ImportError: ./gdchart.so: undefined symbol: gdImagePng I have suceeded (don't remember how) to get passed this error, but then I get something similar for gdImageJpeg. Has anyone succeeded in installing gdchart module on Linux? (I thought I was successful once!) regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Re: [Zope] ZServer Statistics

Analog is a great tool and I have used it under other Web Servers. I wonder if anyone has a working config file which can read the Zope logs and would be willing to share with everyone. I'd be happy to write one, but being realistic since it has been on my to-do list for six months ( I believe that it is item number 351 ;-$ ) I would be fooling myself to think that I could do it in a reasonable time for everyone.

Re: [Zope] Uh-oh, my Zope site is going down the toilet!
by Brad Clements 11 Sep '00

More news, and this looks bad, though I'm happy to have a work-around The ReportForm doc was owned by a user in LoginManager (has roles manager, etc) I was able to Take Ownership as a user in the root acl_users (user folder) and I no longer get the NameError. So .. there's something wrong in that it appears that DTML Documents owned by a LoginManager object don't seem to completely acquire objects from above.. However I'd expect an attributeError, not a NameError, so some of the acquisition machinery works, but something is broken. Does anyone from DC or ZPatterns folks want to play with my site to figure this out?

Uh-oh, my Zope site is going down the toilet! (NameError in DT_Util.py)
by Brad Clements 11 Sep '00

11 Sep '00

Earlier I reported a problem with copy/pasting a DTML method. Now I'm getting a NameError exception in DT_Util.py, line 337 (in eval). This appears to be either an acquisition problem, a security problem or a combiniation in conjunction with LoginManager. (the traceback is at the bottom of this message) Zope version: Zope 2.2.1 (binary release, python 1.5.2, win32-x86) LoginManager-0-8-7a1 Here's my layout / Strader (folder) DateRange (External Method) Outbound (folder) InTransit (DTML Doc) ReportBanner (Dtml Method) Reports (DTML Doc) ReportForm (DTML Doc) acl_users (LoginManager) acl_users (user folder) ReportBanner and ReportForm both use <dtml-var "DateRange(value)[0]"> ReportBanner is called from InTransit, and it works. It works when authenticated via LoginManager or by the root acl_users folder When ReportForm is called from Reports, I get a NameError exception if authenticated solely via LoginManager. However when logged in on another machine, authenticated via Loginmanager, it works. I suspect that copy of the browser is also sending Basic Auth credentials, but I can't be sure. Earlier today I reported that I couldn't copy/paste ReportBanner. It seems that this object, and ReportForm are owned by a user in LoginManager, though I don't know how that happened.. cookie exchange probably. I'm wondering if there's something strange happening with LoginManager, ownership, acquisition and so on. It seems like I can't take ownership of these objects either, and the "make ownership implicit" button doesn't seem to have any effect. So anyway, I'd expect an attributeError or a UnAuthenticated error, but NameError is unexpected and looks very suspicious to me. My customer has spent a *lot* of money on this project so far, and I'm worried that I have some strange bug running through the system now due to these two unexpected problems (copy/paste and now nameerror) I can't think of a workaround for NameError. Thoughts?

newbie dtml-if/expr ?
by Daniel Chudnov 11 Sep '00

(zope-2.1.6, rh6-linux) How come I can't do this: <dtml-if "var1 and var2"> <dtml-call somefuncNeedingVar1AndVar2> </dtml-if> ...or other obvious (e.g. (extra) (parenthesized)) variations thereupon, but the following seem to work: <dtml-if "_.has_key('var1') and _.has_key('var2')"> ... </dtml-if> ...or this... <dtml-if "_.has_key('var1') and _.var2">  ... </dtml-if> ...or even worse, this... <dtml-if var1> <dtml-if var2> ... </dtml-if> </dtml-if> Can't seem to find the answer in the zqr or dtml reference... what am I missing here? Hopefully there's a simple answer. :) Many thanks, -Dan
