CRC-32 checksum
by Jim Sanford 31 Aug '00

31 Aug '00

Does anyone have or know the whereabouts of a python module that will do 32 bit CRC checksums? I am converting an existing application to Zope and need to be able to generate CRC-32 checksums for checking file integrity of software we produce. __________________________________________________________________ Jim Sanford .

Can't connect Zope FTP from NAT
by zope＠suse99.cyberworksolution.com 31 Aug '00

I use reserved IP under NAT and try to connect a remote Zope FTP server. The connection can't be established. But if I am not under NAT and use a legal public IP, the ftp connection is very well. Is there any solution?

indexing pdf files
by Terry Kerr 31 Aug '00

31 Aug '00

Hi, I need to be able to index the text within pdf files. I assume I will somehow use PrincipiaSearchSource, but I need to know how to get the text out of the pdf when it is uploaded to the ZODB. Has anyone done this before? Are there any packages around that I can use that run in python or at least on a linux box that I can pipe to and from? terry -- Terry Kerr (terry(a)adroit.net) Adroit Internet Solutions Pty Ltd (www.adroit.net) Phone: +613 9563 4461 Fax: +613 9563 3856 Mobile: +61 414 938 124 ICQ: 79303381

Re: [Zope] ZCatalog and foreign characters

I have made a very crude patch to "splitter.c" which lets it treat every non-ascii character as a letter. Obviously, this is not correct. It may include punctution into words. This will lead to not find the words unless searched for with the exact same punctuation. Furthermore, non-ascii letters are not translated to lowercase. Up to now, it gives acceptable results for us. However, we did not yet make stress tests. For a correct solution, splitter must be informed about the encoding and a unicode letter classification and case transformation must be applied. If you work with a fixed locale, you can use the "-L" switch to inform Zope about your locale. Then the splitter should work correctly (for your locale). Dieter

worldpilot: copy of message to sent folder
by Marcus Schopen 31 Aug '00

31 Aug '00

Hi there, I'd like to put a copy of each sent mail to a sent folder. Creating folders named "sent" or "SENT" under the INBOX did not help. Further I'd like to send a bcc of each sent mail to an external address. How do I do that? Thanks Marcus --------------------------------------------------- WorldPilot - Get Synced - http://www.worldpilot.org The Open Source Personal Information Manager Server Powered by Python and Zope - http://www.zope.org

_setObject error - urgent!
by Andy McKay 31 Aug '00

31 Aug '00

Hi, I think I have traced my error with cut and paste, I am getting an error on _setObject. If the object is not registered with Zope properly this will be a problem. Basic synopsis: Im importing an object from a script so Im getting a handle to the folder I would like the object to be in: this is obj. Then I call add and set object: obj._setObject(id, globals()[doctype](id, m)) This rather unusual syntax allows me to use a constructor for man different objects. The type is specified in 'doctype', I then get this error: 2000-08-31T16:56:57 PROBLEM(100) ASPNDoc Error: [exceptions.NameError: cat] Any ideas? Thanks in advance

Zope chat
by David Spencer 31 Aug '00

31 Aug '00

I'm not sure what type of chatroom functionality you're looking for, but you might have options through Jabber Instant Messenger (www.jabber.org) which includes a groupchat transport. I have personally been looking at ways to implement the groupchat using a Java applet for specific projects managed through an intranet. As in Lotus Quickplace, when a team member loads the project homepage, I would like for the applet to load automatically, indicating the online presence of other team members and providing the groupchat function. Ideally, this would take advantage of existing zope authentication. I know LDAP and ODBC user storage has been implemented in the CVS version of the Jabber server, so it should be able to query the same user database as zope. There is also an effort to implement the Jabber server and groupchat transport in python at pyjama.sourceforge.net. Information regarding java functionality, including a sample applet I think, can be found at jabberbeans.org. I would love to hear from anyone interested implementing this type of integration between Jabber and Zope.

I would rather like to see one of the OpenSource Chats get integrated into Zope (e.g. get pseudonym from LoginManager UserSource, integrate administration in Zope management interface etc.), I'm not very happy with ZRTChat. http://www.zope.org/Members/jwashin/ZRTChat It's a great example and "100% Zope", but it will (would) need a lot of enhancements for prod sites.

August 2000 14:30 An: zope(a)zope.org Betreff: [Zope] ChatRoom Not Zope specific, but may be important for many web-masters... Some days ago I was told to make a chatroom in our site. I took a look at some products, but no one has satisfied me yet. If anybody knows about _good_ chatroom, please let me know ! Where _good_ means: + highly customizable view of the chatroom + non-flickering refresh (I used jzChat from www.javazoom.net, but it uses JavaScript on client side, so refresh is flickering) So, it should be Java applet on client side. It can be almost anything on server side - Java servlet, Java stand-alone application, native binary program, standard IRC server, CGI script, Zope Product, etc... I don't need many channels at one time. If you have seen (almost) ready-to-use chatroom solution, your help is greatly appreciated ! :) ololo(a)zeus.polsl.gliwice.pl /--------------------------------------\ | `long long long' is too long for GCC | \--------------------------------------/ _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Yes, we're still working on a "broadtree" implementation that may allay some of these problems, although I don't have an ETA. > > It has no published and well defined query syntax (there's > patches here, > bits there, but no definitive document on how to use it, how to batch > with it, how to perform complex and structured queries, particularly > with TextIndex'es) Hopefully, the Zope book will make it more clear from a user perspective, and sometime in the very distant future I will be writing a chapter in the developer's guide about the catalog. I agree that the ZCatalog wrapper should probably wrap more of the underlying catalog's methods, but these need to be rationalized, defined and then documented in the API docs.

This is why the annoying logging code was added to the catalog. It seems to be related to the TextIndex implementation, but I'm still trying to pin it down.
