SOAP is not yet a really active project, so I can't say when it will happen. It is on the (soon to be published) development roadmap. We have some things to do to open up the dev. process and enable the community to really participate - once we have some of those key things out of the way it will be much easier for things like SOAP to get the needed resources...

RE: [ZCommerce] Secure storage of credit card info
by Meilicke, Scott 09 Jun '00

09 Jun '00

Hi there, I know your post indicates you've thought about this, but you may want to reconsider storing CC info at all. It's a trade off on convenience for the customer and security precautions on your site. If you don't have the numbers, that's one less thing an intruder could do with your information when they do break in. If you do store CC info, you should probably offer the option to not store the CC#. I know I don't like my CC info in a merchant database, encrypted or not. Scott -----Original Message----- From: R. David Murray [mailto:bitz@bitdance.com] Sent: Thursday, June 08, 2000 5:57 PM To: zope(a)zope.org Cc: zcommerce(a)codeit.com Subject: [ZCommerce] Secure storage of credit card info OK, any of you out there who have thought about ecommerce, cryptography, and zope, I've got a design question for you. Actually, this question is independent of zope, but I need to solve it in a zope context. You have a ZCommerce site. You accept credit cards, and securely communicate with a CC processor to verify the transacton. Now, you want to save the CC# and other info in case something needs to be done with it later, and probably store the CC# so this customer doesn't have to type it in again later. Regardless of whether you are storing this info in a relational database or in the ZODB, how do you secure that information? Ideally I'd like it to be encrypted on disk. Now, storing it in a database probably makes it pretty hard to grep out even if a hacker manages to snarf the database file, but I'd like to encrypt it. But if I encrypt it, I have to have a decryption key somewhere. Where do I store the decryption key so that the cracker who snarfs the database file can't get it (just in memory somewhere?), and yet have the system be able to boot itself, including having the key, without human intervention? It seems to me like this is a Hard Problem, but I'm not up on the current cyrptography practice. So if there is a well known general solution, I'd love to hear about it. Otherwise, does anyone know what current Best Practice is? --RDM _______________________________________________ ZCommerce Mailing List - ZCommerce(a)codeit.com http://lists.codeit.com/mailman/listinfo/zcommerce

ZDiscussions in classes?
by Alexander Limi 09 Jun '00

09 Jun '00

Hi, I have a problem with getting ZDiscussion working the way I want it to. First a little background, so it becomes easier for me to explain what I want to do: On my site I have several users (called "artists") that I have built a ZClass for. This Artist-ZClass contains a propertysheet with the properties of the artist, it also subclasses ObjectManager, so the artists can add their own pictures in their own object. This works excellent, and I am about to take the next step - adding a discussion forum on each artist, so people can discuss the artist's work directly on his pages. I then tried to add a ZDiscussion Topic ("discuss") in the ZClass. (I also regenerated the methods before proceeding, to get the default interface.) When I tried to access the discussion at: http://my.host/artists/testartist/discuss Zope asks me for a login, and not even the superuser can access it. Either my thinking is screwed up (it often is ;), or it is impossible to accomplish this with ZDiscussions. Could anyone offer me some insight as to what I'm doing wrong here? -- Alexander Limi alexander(a)limi.net

Install problem questions
by Eric Damien Berna 09 Jun '00

09 Jun '00

I'm trying to get Zope to work on my computer, but I'm having a problem that I can't seem to figure out how to fix. I'm installing it on a NetBSD system with the packages system. It seems to install correctly, and at least partially runs, since it does give me an error code. Yet all it does is give me this error code, and nothing else. I've looked through the Zope Web site, and searched the mailing list archives,but I can't find anything that mentions this problem. What am I doing wrong? How can I fix this? Thanks. This is the error in its entirety: Zope Error Zope has encountered an error while publishing this resource. Resource not found Sorry, the requested Zope resource does not exist.

Random line of Products
by Oleg Broytmann 09 Jun '00

09 Jun '00

Hello! I created and published three demo toy Products I named them "Random" Products, because each of them displays text, randomly selected from a list prepared by webmaster. These Products differ in how they store the text items. I learned a good deal of Zope internals while wrote it, and I hope that looking into it will help people to learn Product API. I also run a demo site for these Products. Source code: http://www.zope.org/Members/phd/Random/ Demo site : http://sun.med.ru/pcgi/Random/ DETAILS: The first Product, RandomLine was created from Boring Product - I just learned Product API. The product stores text (edited in a texarea), splits the text into a list of lines and when asked displays a random line. The second Product, RandomLine_v, is just a modified version of the first. The difference is volatile attributes. I found (in RandomLine) that I store both text and splitted list of strings in ZODB. I thought I need to learn volatile attributes and this version stores only text in ZODB. The splitted list stored in a volatile attribute and recomputed when neccessary. The third Product, RandomItem, implements the same idea, but with different implementation. The core class is ObjectManager-derived, and it stores a list of items. Every item in turn stores multiline text. Oleg. ---- Oleg Broytmann http://www.zope.org/Members/phd/ phd2(a)mail.com Programmers don't die, they just GOSUB without RETURN.

If you use more connections in the same dtml-document it may lead into the problems. Imagine: connection1:update table connection2:select from table So connection1-object will never know there is an attempt to read from the table after the update. It will however "commit" the write when the document is fully generated. connection2-object will block therefore. HTH Tino Wildenhain

Can you print out the form variables? Are all the statements inside the same DTML file? It really works fine. Also, make sure that FSSession is in a parent folder of your DTML method.

Zope logging with multilog (daemontools)
by Frank Tegtmeyer 09 Jun '00

09 Jun '00

I provided a document that describes a setup for logging that uses the external logger program multilog. multilog prevents filling the disk, provides filtering by patterns and exact TAI64N timestamps. It is designed to never loose any log data. multilog is part of Daniel J. Bernsteins dameontools package. You may find the article at http://www.lightwerk.de/zope/logging Regards, Frank
