Propert Sheet Question - Never mind
by James W. Howe 25 Jan '00

25 Jan '00

I figured out my problem with my property sheet. When I created my modified property sheet I took the code from a "view source" of my original property sheet form. This included all the tab related stuff including the old URL. James W. Howe mailto:jwh@allencreek.com Allen Creek Software, Inc. pgpkey: http://ic.net/~jwh/pgpkey.html Ann Arbor, MI 48103

Property Sheet Question
by James W. Howe 25 Jan '00

25 Jan '00

I'm experimenting with creating a custom form for managing my properties. In my ZClass, I've created a DTMLMethod which lets me edit my properties. In my Views view, I've selected my custom form as the form for my Properties tab. When I create an instance of my ZClass, I have two views (tabs) defined, Contents and Properties. When I click on Properties, I see my form. However, if I move the mouse over the Properties view, the URL I see in the status pane is different than the URL of the page currently being displayed. For example, the name of the method which displays my form is "manageProperties". When I click on the object to get to the page which shows the Contents and Properties tabs, if I move my mouse over "Properties" I see the URL ".../ZClassInstance/manageProperties". Clicking on this tab displays the proper form. Now when the mouse is over the "Properties" button, the URL is ".../ZClassInstance/propertysheets/instanceProperties/manage". The "instanceProperties" is the name of the property sheet defined for my ZClass. Can someone explain to me what is going on, and more importantly, how to correct the problem? Thanks. James W.

Stupid Zope-related Python Questions
by James W. Howe 25 Jan '00

25 Jan '00

I've written a ZClass which uses a Python Class as it's base. I've written some DTML methods in my ZClass but I've decided to try and convert some of them to Python code. I have a couple of questions relating to how Python works with Zope. First, I know that when I make changes to my Python files I have to restart Zope to have my changes take effect. I know that my source files get recompiled. However, what I don't know is where/how I can see compilation error messages. For example, yesterday I made some changes and my changes had some syntax errors. I restarted the server but noticed that my Product didn't install correctly. I looked and noticed that my .pyc file was missing. I took a look at my source file and found a syntax error. When I corrected it and restarted Zope everything worked fine. There must be some way to either manually compile Python code or somehow get compilation error messages. Can someone help a Python newbie with this simple task? The other question I have concerns how to do some dtml-like functionality in a Python method. In particular, how would I accomplish the same thing that a dtml-with tag might do? For example, the DTMLMethod that I'm converting to Python is a low level instance creation method for my ZClass. It is responsible for making sure the properties are updated and certain objects are added into the object collection maintained by my ZClass. For DTMLMethods, I just call manage_addDTMLMethod. However, I'm also adding an instance of another ZClass I've written, and in the DTML code, I have to do a <dtml-with "manage_addProduct[...]" before I call the add method for my ZClass. What would be a way to accomplish this in Python code? Thanks. James W. Howe mailto:jwh@allencreek.com Allen Creek Software, Inc. pgpkey: http://ic.net/~jwh/pgpkey.html Ann Arbor, MI 48103

Netscape roaming profiles
by Jeroen Baekelandt 25 Jan '00

25 Jan '00

Hi, I tried to use netscape communicators roaming profiles with Zope. Since it has the PUT method, it should work, when setting user_pref("li.server.http.useSimplePut", true); in prefs.js. I created a folder for my netscape roaming user, gave it manager persmissions (just to test). It stored some of the profile files, but also outputs these errors on the console: 2000-01-25T10:01:32 ERROR(200) ZServer Bad HTTP request: * context expression, or when the NVList passed to arguments did not ------ 2000-01-25T10:01:32 ERROR(200) ZServer uncaptured python exception, closing channel <zhttp_channel connected 127.0.0.1:1536 at b084f0 channel#: 245 requests:>exceptions.IndexError:list index out of range [C:\Program Files\ZopeTest\ZServer\medusa\asyncore.py|poll|59] [C:\Program Files\ZopeTest\ZServer\medusa\asyncore.py|handle_read_event|291] [C:\Program Files\ZopeTest\ZServer\medusa\asynchat.py|handle_read|128] [C:\Program Files\ZopeTest\ZServer\medusa\http_server.py|found_terminator|476] [C:\Program Files\ZopeTest\ZServer\medusa\http_server.py|join_headers|672]) ------ 2000-01-25T10:02:35 ERROR(200) ZServer uncaptured python exception, closing channel <zhttp_channel connected 127.0.0.1:1552 at b4b620 channel#: 260 requests:1> (exceptions.AttributeError:data [C:\Program Files\ZopeTest\ZServer\medusa\asyncore.py|poll|59] [C:\Program Files\ZopeTest\ZServer\medusa\asyncore.py|handle_read_event|291] [C:\Program Files\ZopeTest\ZServer\medusa\asynchat.py|handle_read|103] [C:\Program Files\ZopeTest\ZServer\medusa\http_server.py|collect_incoming_data|435] [C:\Program Files\ZopeTest\ZServer\medusa\http_server.py|collect_incoming_data|143] [C:\Program Files\ZopeTest\ZServer\HTTPServer.py|collect_incoming_data|300]) Any ideas?

Downloadable list archives
by Lalo Martins 25 Jan '00

25 Jan '00

The downloadable list archives would IMHO be more useful if they could just be loaded on any mail program and read as if you're a subscriber since the beginning. For that to work, they need: 1: to have their ``From '' lines in the correct date format; currently is >From mike(a)digicool.com Mon, 10 Jan 2000 15:03:23 -0500 (EST) but the correct is >From mike(a)digicool.com Mon jan 10 15:03:23 2000 -0500 I know this sounds like excess nitpicking, but some mail clients don't recognize the line as a message separator if it is in an incorrect format. 2: maintain the Message-id, References and In-reply-to headers, so we can thread them decently (and new messages will just plug themselves in the existing threads if that is the case).

pcgi-wrapper.exe
by Larry Luther 25 Jan '00

25 Jan '00

pcgi-wrapper.c bugs & programming oddities * The first error stems from using strlen and atol on a buffer which has not been null terminated. The program works because the programmer got lucky because the buffer is followed by a pointer which is initialized to zero and is never used. In "main": char t[10]={0}; should be char t[HDRLEN+1] = {0}; * Remove estatus & emsg, they are not used. * sizeof(char) is used liberally, but according to "The C Programming language" 2nd edition ANSI version. "sizeof(char) == 1", see Pg 204 under A7.4.8. When "sizeof(char)" is replaced by "1", the code simplifies nicely. * After "Receive stdout and stderr" buffers are allocated one byte larger than necessary and the whole buffer is cleared before the read. Both operations can be removed and the code cleaned up. Larry

RE: [Zope] Oracle or PostGreSQL connection pool

Oracle Yes, PostgreSQL is not written by DC so I don't know. I suspect yes. > If I create a connection object, supposedly it may only be used by a > single thread. Not on Oracle. The Oracle DA is fully concurrent. Postgres, I don't know. Possible not. Note that if a DA is not concurrent it's not Zope's fault, it's usually because the client libraries to interface that database are not concurrent. > I'd like to use ZSQL methods but my application should be very > concurrent. Then stick with Oracle. -Michel

Fwd: Rename BUG
by Thomas 25 Jan '00

25 Jan '00

Hello again List, I have finally fixed the bug... temporarily. I had multiple catalogs and it appeared that Johnathon's idea worked. (Thanks again Johnathon) I exported all of the Catalogs and then deleted all of them... this enabled me to rename all my objects. <phew> On that note though, is this planned on being fixed in the next release of Zope?
