ProxyPass: How to get around it.
by The Doctor What 06 Apr '01

06 Apr '01

The idea: I have a site (http://dd.gerf.org/) which works great, it's zope, and it uses ProxyPass (because I have a lot of virtual hosts). However, the bug tracking system I want to use (because I didn't find any good zope ones) requires PHP. So I have it set up as /bugs. But Alias isn't working. I found a page that mentions that you can try to punch a hole using additional proxypass settings, but since this is a virtual (CNAME) host, not a separate IP address, I can't use localhost or some such. And if I say: ProxyPass /bugs http://dd.gerf.org/bugs I get an infinite loop. I tried moving it over to http://gerf.org/~nick/bugs, but that'd require a whole rewrite of the php scripts as they call PHP commands to ask Apache it's host name, which ends up being gerf.org, which is wrong. So, all I want is an Alias that can punch a hole in my ProxyPass. Ciao! -- A computer scientist is someone who fixes things that aren't broken.

QSurvey problem with 2.3.1

Hi all, I was wondering if anyone could provide a pointer as to why the following debug notice comes up. The QSurvey surveys worked under 2.3.0 however now don't under 2.3.1 . Thanks Oliver Debug notice: Traceback (innermost last): File /home/zope/local/test/2.3.0/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /home/zope/local/test/2.3.0/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/zope/local/2.3.0/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /home/zope/local/test/2.3.0/lib/python/ZPublisher/Publish.py, line 171, in publish File /home/zope/local/2.3.0/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: survey) File /home/zope/local/test/2.3.0/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: survey) File /home/zope/local/test/2.3.0/lib/python/OFS/DTMLMethod.py, line 189, in __call__ (Object: survey) File /home/zope/local/2.3.0/lib/python/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: survey) File /home/zope/local/2.3.0/lib/python/DocumentTemplate/DT_Let.py, line 147, in render (Object: do_survey="1") File /home/zope/local/test/2.3.0/lib/python/OFS/DTMLMethod.py, line 182, in __call__ (Object: filethedata) File /home/zope/local/2.3.0/lib/python/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: filethedata) File /home/zope/local/2.3.0/lib/python/DocumentTemplate/DT_With.py, line 146, in render (Object: RESULTS) File /home/zope/local/2.3.0/lib/python/DocumentTemplate/DT_Try.py, line 212, in render File /home/zope/local/2.3.0/lib/python/DocumentTemplate/DT_Try.py, line 246, in render_try_except File /home/zope/local/2.3.0/lib/python/DocumentTemplate/DT_With.py, line 133, in render (Object: QSurveyResultsItemClass.createInObjectManager(id=surveyid, REQUEST=REQUEST)) File /home/zope/local/2.3.0/lib/python/DocumentTemplate/DT_Util.py, line 334, in eval (Object: QSurveyResultsItemClass.createInObjectManager(id=surveyid, REQUEST=REQUEST)) (Info: REQUEST) File <string>, line 0, in ?

RE: [Zope] Can Zope act as an XML capable http client?
by Schmidt, Allen J. 06 Apr '01

06 Apr '01

I too have a need for this. We have sample URLs from a group offering data to us. They are basically standard URLs with various arguments attached to the ends. The data returned is all tab delimited text and not structured at all on the browser. A quick view source shows all the field names at the top with a <COLUMNS> field1, field2, etc. </COLUMNS> and then the data values as <DATA> value1, value2, etc. </DATA> I have been told the result of the query is a pure XML stream and need an XML parser to be able to use it. Will ParsedXML handle this? Is it relatively straightforward to use? I tried installing on a Win98 test Zope 2.3.1 and got a variety of errors and have not had time to go back to it. I will hang up and listen now...

Zopistas, The subject line says it.. I am trying to connect up to a legacy FileMaker system which can act as a web server, serving up generic HTTP content. I'd like to structure the templates so that this content is available on the web in XML format. Can I use Zope to connect to this DB and download the XML via regular HTTP, and then parse it? Id like to then be able to write it to *my* database using a ZSQL method..

html quote of property sheets
by Pierre-Julien Grizel 06 Apr '01

06 Apr '01

Hi there, If I type for example "<" in the title property of a DTML Document, it is showed as "<" when I valid the property form. If I do the same with a Folder, it is rendered as "<", which is the normal and safe behaviour (and is the behaviour of 1.2.x versions). I'm using the 2.3.1b1 version of Zope. Any clues ? Regards, P.-J. -- If the only tool you have is a hammer, you tend to see every problem as a nail.

Hi, I am dealing with Zope for a week now. I try to learn how the tree tag works. Thereto I've got a question and maybe somebody on this maillinglist can help me?! In the tree code of the Qickstart/index_html this code is given: <IMG SRC="/Outline/OpenBook.gif" ALIGN="TOP" BORDER="0"> ^°°°°°°°°°°°°°°°^ Where do I find the definition of the variable BASE2? Am I right that the variable contains a part of the path? Thanx Uli __________________________________________________ uli(a)highq-it.de

LoginManager Mania
by Andrew Athan 06 Apr '01

06 Apr '01

So I've been reading the source of LoginManager 0.8.8 for a while now and I'd love for someone to explain why what I'm about to say is crazy: There's some silliness going on in there with respect to handling presentation of the login form. Specifically: (1) findLogin of the BasicCookieLogin has an if which seems to be trying to use the loginForm DTML Document form values in the case that there is no cookie information about the user. Thus it seems the author intended for the loginForm to come up in response to any "unauthorized" access. The submission of that form would then "authorize" the user the second time around. I don't see how this would ever happen, though (see 2) (2) loginManager.py's lm_unath() functions, which replace response.unauthorized() when no user can be identified (such as in 1, when first accessing any page) both "append" the old() unauthorized() function to the loginForm DTML Document which they invoke. This old() seems to be the unauthorized() implementation found in HTMLResponse of Zope. What it does is to eventually raise an unauthorized exception, and this results in sending back a 401 w/ the WWW-Authenticate header that causes the panel to pop up for login. This prevents the loginForm DTML form from ever displaying. So what were the authors thinking here? Am I supposed to put a <dtml-try> in the standard document header and handle the unauthorized exception in some standard way in the footer? Just doesn't seem to make sense unless LoginManager was meant to be a top level user_folder and all this is left over or half-finished cruft. A. PS: This stuff needs to get an order of magnitude less painful to deal with, no?

Generic Sort External Method
by Oleg Broytmann 06 Apr '01

06 Apr '01

Hello! On http://www.zope.org/Members/phd/Sort/ there is the generic Sort External Method that helps programmers to sort their sequences according to their needs. It can sort by a key, by multiple key, in ascending/descending order (different order for any key possible), by locale rules, ignoring case and, best of all, it allows developer to write his/her own comparison function for a key. Example: Sort(sequence, "akey/nocase,anotherkey/cmp/desc") This, of course, is a variant of my patch for dtml-in (http://classic.zope.org:8080/Collector/2120/view) I am not going to drop one of them in favor of the other - both have its niches. There is a command-line test suite and a Zope test folder. Oleg. ---- Oleg Broytmann http://www.zope.org/Members/phd/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

Acquisition problem?
by Andrew Athan 06 Apr '01

06 Apr '01

I'm trying to use LoginManager and am running into a little problem, which I'm sure is based in a not-deep-enough understanding of acquisition issues. Bloop ---acl_users ------Z MySQL DA ------SQL_get_password [SQL Method, taking username & password parameters, tested & works] ------xuserAuthenticate [DTML Method: contains the line <dtml-in "SQL_get_password(username='foo',password='bar')">] ------Test [DTML Method: contains the line <dtml-let ret="xuserAuthenticate(username='foo',password='bar')"> If I try to "view" Test, then I get the nasty traceback below. If I view xuserAuthenticate, no such error is reported. I suppose this is because dtml-let puts a "strange" acquisition context in place during the execution of xuserAuthenticate...an execution context that does not include the containing folder of Test (namely acl_users). Or is this due to some strange properties that I am not yet familiar with of acl_user folders?

Re: Text truncated by Netscape (but not by Explorer)
by Pierre Dricot 06 Apr '01

06 Apr '01

Finally, we have found the solution by using the following tag <dtml-var expr="_.string.split(AUTEUR_BIO_FR)"> to display the text really transmitted through ODBC: ['Vous', 'n\222\351chapperez', 'pas', 'au', 'Colonel', 'Moutarde', '!', 'De', 'MADAME', 'FIGARO', '\340', 'MODES', '&', 'TRAVAUX,', 'Moutarde', 'enlumine', 'les', 'pages', 'des', 'plus', 'grands', 'ma\000gazines.', 'Des', 'INROCKUPTIBLES', '\340', 'OKAPI,', 'le', 'Colonel', 'baladait', 'son', 'charme', 'et', 'ses', 'images', 'aux', 'couleurs', 'lumineuses', 'quand', 'la', 'passion', 'de', '\000la', 'BD', 'l\222a', 'surpris', 'au', 'd\351tour', 'd\222une', 'page', 'de', 'L\222\311QUIPE', 'MAGAZINE.', 'Et', 'en', 'bande', 'dessin\351e', 'comme', 'en', 'illustration,', 'le', 'Colonel', 'Moutarde', 'd\000onne', 'le', 'meilleur', 'de', 'lui-m\352me', '!'] As you can see, there is a special caracter \000 is some words most probably inserted by SQL Server every 125 caracters and Netscape reacts inconsistently. The solution was simply to remove this caracter with the following tag: expr="_.string.replace(AUTEUR_BIO_FR,'\000','')" So the problem wasn't inside Zope... > Pierre Dricot a écrit : > > > A long text description is stored as ntext(16) in a MSSQL7 database and > > retrieved trough ODBC (ZODBCDA-3.1.0b2-win32-x86).

It happens only if the zipfile is unreadable for zipfile.py, the constructor leaves the temporary file open, os.unlink() fails. Do you use the Windows Binary distribution of Zope?
