I have 1.5.1 and it failed for me. Is the zlib.pyd in 1.5.2 based on a newer version of the zlib library that may not be forward compatible? -- Robin Dunn robin(a)AllDunn.com http://AllDunn.com/robin/ http://AllDunn.com/wxPython/ Check it out!

(Dummy Dummy Dummy......) I should have known that, it was a stumbling block with Mac cgi's, but I never noticed it when I checked http_server.py. I imagine that will fix it.

Request.py and duplicate column names
by TFE MMS JARVIS JOHN 02 Mar '99

02 Mar '99

Hi All! First off, I'd like to thank Digital Creations for an excellent (and really fun) product. I'm building a prototype web site interface for a database where I work using Zope 1.10.2 and the ZOracleDA product and have a some questions. 1. When trying to do a join (a lazy query, I know) like: select a.*, b.* from tablea a, tableb b where a.b_id=a.id Both tables have an ID column so Zope raises a 'ValueError' exception with the message 'Duplicate column name, ID'. I wonder if instead of raising an exception something like the following could be done? A diff of Shared/DC/ZRDB/Results.py: 120,131c120 < #raise ValueError, 'Duplicate column name, %s' % name < < #instead of error, append an extension to < #create a unique name < tempname=name < nameext=1 < while schema.has_key(name): < name=tempname+'_'+str(nameext) < nameext=nameext+1 < < #update with newly created name < item['name']=name --- > raise ValueError, 'Duplicate column name, %s' % name I tested this some and it seems to work. Are there any problems that could be caused by doing this? 2. I'll post the other questions separately because they are unrelated. TIA!, John Jarvis Tokyo Electron, FE Ltd.

Not really -- you can't access _getPassword() from DTML. You would have to write an external method to do that (which implies that you have access to the filesystem, and could get the passwords anyway if you wanted them that bad...)

Zopistas Seems that the activity on the Zope list has exploded. A lot of the questions I read in the posts have been raised many times in the past. I believe a FAQ on the Zope site is neccessary. Do the folks at digital creations have time to set it up? Pavlos

ZServer and MSIE (long & detailed)
by Dave G 02 Mar '99

02 Mar '99

Has anyone else experienced a problem getting Explorer to connect with Zserver? I have no problem with any version of Navigator but MSIE 3.01 and 4.0 and 4.5 for both Mac and Windows throw up an error box claiming an "error with Explorer's internet extensions has failed". Very baffling, I can connect just fine via telnet using the following requests, ZServer (medusa) returns a proper html page. Requests sent: GET / HTTP/1.0 Connection: Keep-Alive Host: www.fishwrapper.com Accept: image/gif, image/jpeg, */* GET / HTTP/1.0 accept: image/gif, image/jpeg, */* GET / HTTP/1.1 accept: image/gif, image/jpeg, */* response recieved: Status: 200 OK Content-Length: 1307 Content-Type: text/html <html><head> <base hr ef="http://chestnut.netraven.com/"> </head> blah, blah, blah..... (note the difference in the sent host and recieved host, the host arg in the start script sets the host for the ftp server, not the webserver...) I can see nothing in the responses that would cause MSIE to fail, note this has been tested from four different PC's on three different ip's, including a local connection from my Lan. Strangly enough I did a stream capture and hit my server and the startship server (also running ZServer) and the two responses differ even though the requests were from the same browser on the same connection. request for http://www.fishwrapper.com/ followed by my servers response : Send 357 bytes on stream 4. <00000000< GET / HTTP/1.0 <00000010< Connection: Keep-Alive <00000028< User-Agent: Mozilla/4.5 (Macintosh; I; PPC) <00000055< Pragma: no-cache <00000067< Host: www.fishwrapper.com <00000082< Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, <000000BF< image/png, */* <000000CF< Accept-Encoding: gzip <000000E6< Accept-Language: en <000000FB< Accept-Charset: iso-8859-1,*,utf-8 <0000011F< Cookie: sql_pref__rows="10"; sql_pref__cols="65"; dtpref_cols="9 <0000015F< 5" <00000163< Receive 1364 bytes on stream 4. >00000000> Status: 200 OK >0000000F> Content-Length: 1303 >00000024> Content-Type: text/html >0000003C> >0000003D> <html><head> blah, blah, blah..... request for http://starship.python.net/ followed by starship's response : Send 276 bytes on stream 1. <00000000< GET / HTTP/1.0 <00000010< Connection: Keep-Alive <00000028< User-Agent: Mozilla/4.5 (Macintosh; I; PPC) <00000055< Host: starship.python.net:9673 <00000075< Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, <000000B2< image/png, */* <000000C2< Accept-Encoding: gzip <000000D9< Accept-Language: en <000000EE< Accept-Charset: iso-8859-1,*,utf-8 <00000112< Receive 1254 bytes on stream 1. >00000000> HTTP/1.0 200 OK >00000011> Server: Medusa/1.4 >00000025> Content-Length: 1112 >0000003B> Content-Type: text/html >00000054> Connection: close >00000067> Date: Tue, 02 Mar 1999 02:24:00 GMT >0000008C> >0000008E> <HTML> >00000095> <HEAD> blah, blah, blah..... Do starships ZServer and mine differ? My http_server.py script carries RC_ID of: "v 1.4 1999/01/18 22:44:49 amos" I downloaded a fresh copy of ZServer when I grabbed the newest copy of Zope. Any clues? I've been documenting and testing everything I could think of, I'd report a bug but it seems MSIE works with the Starship server, so I think it's not a bug so much as something wrong on my end?

calling a function with arguments?
by julian＠zereau.net 02 Mar '99

02 Mar '99

I want to call a function I have made, with arguments. 1) is there any way to call it direct, complete with module name? It would mean getting Zope to import that module. 2) I know I can put it in an external metod and use  but it needs arguments, so I'll need to set and re-set the same DTML-namespace variable throughout the document, in which case, how do I alter/set DTML varibles from within DTML? --- Julian Morrison Programmer (Zereau Ltd)

In this case imports in the method's file work fine, but only inside Zope's search path (practically, the installation path and lib subdirectory).
