I would *not* be suprised. I believe that the problem is that medusa's ftp server wants to look up the hostname of the server machine. On Win95 machines which are not connected to a network this fails. I think that this can be fixed by adding an entry in your Win95 hosts file (\windows\hosts) like so: 127.0.0.1 localhost If I recall correctly, I think that a hosts file doesn't exist by default on Win95 machines. But there may be a sample hosts file in \windows\hosts.sam. That said, I think that medusa's ftp server shouldn't have to make this host name lookup. I am looking at implementing a fix/work around for this and submitting it to Sam Rushing. I'll also add this information to the ZServer INSTALL.txt file. -Amos

My guess is IP_ADDRESS in your start.py is not set right, however I believe it defaults to 127.0.0.1, does Win95 not have a 127.0.0.1 (loopback) interface? I would *not* be suprised. -Michel localhost 127.0.0.1 is set in the hosts file of windows. Also the names and the IP-adresses of my two PC's on that network. Now, I've changed several values in start.py, I've changed Hostname to the name of my server and changed the paths etc in start.py. It still gives this error (see previous message)... :-( Tom.

RE: [Zope] Could we migrate Zope email to a news group?

[I accidentally sent this directly to the poster first. If I could make a suggestion: Maybe the list admin could have the list output a correct Reply-To field. That would be good.] I suggest a dual news/list solution, which has been successfully (at least according to Mr. Udell) deployed by Byte and others. By this I mean a new server which replicates to the mailing list, and a mailing list that replicates to the news server. It works, and gives you pretty much the best of both worlds.

I have a tabular object with a column() method which returns a Results object containing information about the table columns. This lets me programmatically build results tables pretty nicely: <TABLE BORDER=1><TR>  <TH></TH> </TR>  <TR> <TD></TD> </TR>  </TABLE> However, when I want to try to do some summary statistics on the tablular object where I build the stat-name, it appears the statistics() method looks at the wrong results object. <TABLE BORDER=1><TR> <TH></TH>  <TH></TH> </TR>   <TR><TD># Items</TD>  <TD></TD> </TR>   </TABLE> When statistics() iterates over the results objects, it can't find the item 'name' using either getitem or mapping because the 'item' dictionary contains : {'__module__': 'Shared.DC.ZRDB.Results', '__doc__': None} instead of just the results object which should contain the item 'name'. Even if I explicitly name the 'count-column' name, it still isn't finding the correct object, so I don't think that I'm off-base using "_['count-'+colname]". Any clues as to what I'm doing wrong here such that the statistics method can't seem to point at the correct object? Why can  A obtain the correct value, but  can't? Thanks Kent

Installing ZServer
by Tom Deprez 05 May '99

05 May '99

Hi, Still in my 'Zope hype' I installed it on my old DX2 66Mhz pc with Windows95. It works!!!. I've installed 1.11 and I like it even better then 1.10.2 ... if you keep going like this.... what will 2.0 become? Better graphics also! :-) I must say that it is slow (slower then 1.10.2).... but I guess this is normal seeing my computer configuration... :-) Now, I wanted to try out the ZServer instead of the ZopeHTTPServer. So I created the following batchfile : set ZOPE_DEBUG_MODE=1 set PYTHONHOME='D:\WebSite\' "D:\WebSite\bin\python" "D:\WebSite\ZServer\start.py" However, I always get the following error : log: adding channel <trigger at 920320> Traceback (innermost last): File "D:\WebSite\ZServer\start.py", line 96, in ? from FTPServer import FTPServer File "D:\WebSite\ZServer\FTPServer.py", line 140, in ? from medusa.ftp server import ftp_channel, ftp_server, recv_channel File "D:\WebSite\ZServer\medusa\ftp_server.py", line 58, in ? HOSTNAME = socket.gethostbyaddr (IP_ADDRESS)[0] socket.error: host not found What am I doing wrong? Regards, Tom.

DTML methods vs. documents for index_html
by Jimmie Houchin 05 May '99

05 May '99

Hello, I am working on my understanding on DTML methods and documents. I've read previous posts and the ZDP FAQ and this is my understanding. Feel free to enlighten my understanding. :) >From Michel in the thread, DTML Method vs Document At 05:24 PM 3/3/99 -0500, Michel Pelletier <michel(a)digicool.com> wrote: > >This is my take on the situation.

DTML Documents have >properties which may interfere with aquisition you'd want to do, and >aquisition is from their own point of view, which may not be what you >want. By the way I find this to be a most excellent explanation. For the default public interface of a folder, it seems to me that it should be a DTMLMethod. In browsing a default install of Zope 1.11.0pr1 the top level folder's default interface is a DTMLMethod, likewise the QuickStart. When you add a Folder and check Create Public Interface and then click add it adds a DTMLDocument not DTMLMethod. Is this the currently desired effect? Or is this legacy functionality due to pre 1.10.x and DTMLMethods? If so would the following be a reasonable way to handle the current philosophy? (According to my understanding.) In /python/OFS/Folder.py I see line 119 which says: if createPublic: i.manage_addDTMLDocument(id='index_html',title='') To change the default is all I need to do is change it to? if createPublic: i.manage_addDTMLMethod(id='index_html',title='') Thanks, Jimmie Houchin

Error in QuickStart 1.11.0pr1
by Jimmie Houchin 05 May '99

05 May '99

Hello, I just downloaded Zope 1.11.0pr1 and was attempting to go thru the QuickStart when I got an error stating. Resource not found. I viewed the QuickStart index_html without problem. I click on any of the links to view further information and get the error. This is all with a default binary install of the Win32 version into it's own directory. This traceback is in the page source.  Is the QuickStart not complete? Thanks, Jimmie Houchin

"critical" as in "confidential" or as in "requiring urgent (quick) delivery". If "confidential", I'm not aware of seeing confidential info on these lists. If "urgent", what I see on these lists is no more time critical than what happens on other popular news groups -- take the python news group as an example, and anyway, my experience with USENET is that it isn't that much slower than email. Which isn't to say that the email lists shouldn't exist, but that they should be reduced to two flavors: a moderated announce list, and an insiders list for a few who are highly active in Zope (and I have concerns that this second flavor would initially weaken the news group, by siphoning off good questions and some of the best experts -- perhaps the "zope(a)zope.org" list would need to be replaced with an autoresponder, sending all non-followups a message inviting them to resubmit their message, to the news group). In short: What's good enough for Python (comp.lang.python) is good enough for Zope. It's time Zope had a strong news group presence. ======================================================================= I won't rest till it's the best ...
