domains (acl_users) and access via proxy
by Didier Georgieff 04 Sep '00

04 Sep '00

Hello, Our users are acessing to the Zope server thru corporate (ministers) proxys. I can't get the "domains" working, while trying (agriculture.gouv.fr, gouv.fr, fr) even with simple one. I'm suspecting some changes in the REQUEST made by the corporate proxys. Is there any doc about what REQUEST variable is used in the "domains" restriction ? (I have a HTTP_FORWARDED with the *proxy* name (unfortunately without the .gouv.fr). I can't find anything on the site and the list either. Thanks in advance.

I, myself, have seen a very similar problem -- with Netscape 4.5.1 under Solaris 2.7. I tried to analyse it, but failed. I can say, that is was *not* the Netscape image bug (Netscape sends If-Modified-Since headers with two year digits). Inside Zope's "OFS.Image.File.index_html" everything looks fine. Dieter

Re: [Zope] Way to list vocabulary words specific to a page?

Kevin Smith writes: > I am interested in showing the vocabulary words indexed for the page being viewed, to be used as meta keyword data. > > Is this possible? Zope does not manage vocabulary words on a page basis. Therefore, you cannot simply ask: "give me the words for this given page". With some effort, you can emulate ZCatalogs word splitting: given an object, "o", and an attribute, "a", to be indexed, ZCatalog first determines "o"s "a" value: val= getattr(o,a) if callable(val): val= val() The resulting string is then fed to a C implemented module called "Splitter" which splits the text into a sequence of words. It is this sequence, you are interested in. You will probably need to write an external method. You will find the relevant code in "SearchIndex.UnTextIndex". Dieter

Not like ASP complaint - any good answers
by Sean McGrath 04 Sep '00

04 Sep '00

All, I have had a number of e-mails from developers using Microsoft ASP in recent days. The paraphrased consensus in the e-mails is that the external methods/python methods approach to mixing markup with code in Zope is more clunky than in ASP where you can intermingle the two at will. Has anyone written anything on this topic I could point them to? regards, Sean http://www.pyxie.org - an Open Source XML Processing library for Python

Re: [Zope] If-Modified-Since problem again?!

No traceback, because no exception. I speak of a true rounding problem: the image is modified at "x" (expressed in seconds) Zope sends "x" converted to a date/time string as "Last-Modified" Zope receives the date/time string back as "If-Modified-Since". Zope converts it to a "long", say y. *BUT* y is not x, it is "x-1". Of cause, this does not happen for all modification times. But there are not too few of them. Dieter

Re: [Zope] Non-blocking MailHost
by Richard Taylor 04 Sep '00

04 Sep '00

I think what people have in mind (correct me if I am wrong) is something that will accept messages (for posting to the mailhost at some time in the future) and then immediately return. I guess it would spawn another process/thread to do the posting asynchronously. The problem, as I see it is how to handle an error with the posting. The user who submitted the mail is now long gone so it must be left to an administrator to pick up the pieces. Perhaps the posting routine could accept a user (developer) provided exception handler that gets called if a posting fails. It maybe better to just hand this off to a completely separate program rather than try to handle it within a zope thread.

Catalog AND Zieve
by Menard.Jean-Francois＠hydro.qc.ca 04 Sep '00

04 Sep '00

I'm trying to use the Zieve product with my Catalog to sort the results on a variable key. Since the Catalog do not return the actual objects, how can I use Zieve with it? Maybe an external method returning the object list? If so, how shold I do that?

Hi all, I am getting the following error when i try to install the portal toolkit with the ' experimental login manager support'. I am using the zpatterns version : ZPatterns-0-4-1snap1and demo portal : 0.8.2 and other products. If I create the portal with no initail member then i am able to have a portal with login manager support. But then after I have installed the portal I am unable to add a member. ?? Can i have a working snapshot of the portal toolkit with the login manager for a windows version or probably a direction as to how to go abt fixing the above problem?? -neeloy ============================================================================ ================================= Error Type: NameError Error Value: client File C:\Program Files\WebSite\lib\python\Products\ZPatterns\DataSkins.py, line 377, in _v_currentSheets (Object: wqeqw) NameError: (see above) ============================================================================ ================================================= Traceback (innermost last): File C:\PROGRA~1\WebSite\lib\python\ZPublisher\Publish.py, line 222, in publish_module File C:\PROGRA~1\WebSite\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\PROGRA~1\WebSite\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: RoleManager) File C:\PROGRA~1\WebSite\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\PROGRA~1\WebSite\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: Portal_add) File C:\PROGRA~1\WebSite\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: Portal_add) File C:\PROGRA~1\WebSite\lib\python\OFS\DTMLMethod.py, line 167, in __call__ (Object: Portal_add) File C:\PROGRA~1\WebSite\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: Portal_add) File C:\PROGRA~1\WebSite\lib\python\DocumentTemplate\DT_With.py, line 146, in render (Object: Portal.createInObjectManager(REQUEST['id'], REQUEST)) File C:\PROGRA~1\WebSite\lib\python\DocumentTemplate\DT_Util.py, line 337, in eval (Object: apply_wizard(REQUEST)) (Info: REQUEST) File <string>, line 0, in ?

sending mail slow?
by Chris Withers 04 Sep '00

04 Sep '00

Hi, I've noticed that sending mail from within Zope the <sendmail> tab or mailhost.send() is very slow (like it adds a few seconds to the time it takes to get a page back from a post). Why is that? how can I make it faster? I'd thought about having the actual mail sending done in a different thread/process but I don't know how I'd do that or whether it'd be worth doing. I wonder where the slowness is coming from :S cheers, Chris
