Limitations of just using External Methods ?
by chas 26 Mar '99

26 Mar '99

Hi zoppelgangers, I have several applications built 100% with python CGI scripts that I'd like to run on Zope. The reason for this are : a) For the better performance (I was worried about the scalability of CGI for high-availability and knew I had to move to FastCGI or the equivalent) b) I really really like the way Zope takes care of the CGI variable handling (ie. declaring the HTML form fields as arguments in the python method). However, I don't really want to use DTML at all. The reasons is that I find it much harder to read than pure Python. This is just a personal aesthetic thing and no criticism of Zope at all (full kudos to Digicool on an excellent application). It's just coding aesthetic : I like it all kept in Python, like servlets in java (as opposed to CFML, ASP etc). So, I've put all of my CGI scripts in a newly-created extensions directory and registered them via the Zope web-manager. It was, as the documentation says, incredibly simple and it seems to work for simple methods. (I'll declare my own packages later). Now, if I just use External Methods like this (using my own ex-CGI Python scripts to query databases, IMAP etc), am I missing out on any of Zope's main benefits ? In particular, the cache management ? Would I have to turn my stuff into a Zope Product to get these benefits ? (I've not had too much joy with the Product stuff yet) chas

I have a Zope sandbox which I would like to use to play with new features as they become available. Unfortunately, for the past several days my sandbox server has been broken because ExtensionClass/ComputedAttribute.c is missing. Is it missing on purpose? If so, is there a way I can work around it?

Probably be a two step procedure, 1) try to match the error by string exactly, otherwise 2) evaluate each handler in turn and see if the exception isa class. > Another small nit is that I think that you should use 'error_message' and > 'error_type' like standard_error_message does rather than 'errmsg' and > 'errname'. I have fixed this in 0.1.1 of the Product which is now available from the same directory as the original. I've also made some other additional fixes relating to the default error handler.

Ok, the problem was that I had the roles defined on the top level folder and the users defined in the subfolder. By moving the roles into the subfolder, the problem went away. --- John Eikenberry [jae(a)kavi.com - http://taos.kavi.com/~jae/] ______________________________________________________________ "A society that will trade a little liberty for a little order will deserve neither and lose both." --B.

Anonymous after logging in?
by John Eikenberry 25 Mar '99

25 Mar '99

Hello, I'm having a strange problem with logged in users getting to anonymous areas of the site. Here's an simplified example to explain... Two directories off the / /private /public /private allows no access to "Anonymous User", requiring a login. There are no usernames in /acl_users. All the user info for logging into /private is kept in /private/acl_users. /public has no acl_users folder. If you start up netscape, you can get to /public without any problems. But once you've logged into /private, you can't get back to /public without getting an unauthorized error... You are not authorized to access this resource. Username and password are not correct. Traceback (innermost last): File lib/python/ZPublisher/Publish.py, line 877, in publish_module File lib/python/ZPublisher/Publish.py, line 531, in publish (Info: /MCExam) File lib/python/ZPublisher/Publish.py, line 297, in unauthorized Unauthorized: (see above) Any tips about how to fix this. Note that the login info has to stay in /private/acl_users (they can't be moved to /acl_users). Thanks, --- John Eikenberry [jae(a)kavi.com - http://taos.kavi.com/~jae/] ______________________________________________________________ "A society that will trade a little liberty for a little order will deserve neither and lose both." --B.

Hi there, Though the ZDP FAQ hasn't moved at the relentless pace it did before this week, there's still a new version of the FAQ at zdp.zope.org. It's a fairly minor change, but you might find some things that are useful to you. Of course, if you haven't seen it yet, go rush over! Happy Zoping, Martijn

The Artist Formerly Known as NotMail
by Michel Pelletier 25 Mar '99

25 Mar '99

Greetings, For those of you interested in the NotMail project we have some announcements. First, Digital Creations has officialy adopted NotMail as one of it's products. Second, in an attempt to make the products at least *sound* more mature :), we are changing the name. Third, in the last two weeks I have been working pretty hevily on NotMail and it has changed significantly. Therefore: NotMail is, for the interum, called The Artist Formerly Known as NotMail (TAFKAN). We still call it NotMail, but that's just our code word. TAFKAN was once a product, but now it's just a bunch of dtml methods. The actuall imap functionality that TAFKAN needs has been abstracted into another product called IMAPAdapter. IMAPAdapter is very early alpha software. It has several known bugs, and Linus knows how many unknown ones. Your millage may vary. It may light your computer on fire. It might delete all your mail and crash your imap server. It might send insults in your general direction. You get the point. IMAPAdapter is, in Zopespeak, a 'user database'. Other examples of user databases are User Folder, UserDb Folders, and etcUserFolders. IMAPAdapter walks, swims, and quacks (to quote Jim) like any other type of user database. The simplest example of using IMAPAdapter is: Create an empty folder without an 'acl_users' Add an IMAPAdapter (it will automagicly call itself 'acl_users'), telling it where to find it's imap server, what default roles to assign to users, and other misc stuff. Create a DTML Method called index_html containing the following DTML:    <img src=>   ()     Going to this file will prompt you for a username and password (assuming you've correctly set the permissions and roles). The username and password you enter here must be a valid IMAP login for your imap server. It is *not* necessary to add a Zope user to Zope, IMAPAdapter will try your uid:pwd pair against the IMAP server and validate/deny you based on the sucess or failure of making an IMAP connection. What you will see when you look at this DTML Method is a pretty #tree breakdown of all your imap namespaces, folders and subfolders. IMAPAdapter, like all other user databases, contains a validate() method that Zope calls to authenticate a user. This method returns an imapUser object (which inherits BasicUser, like most other Zope user objects). This user object is what AUTHENTICATED_USER refers to. imapUser exposes the imap API to the DTML programmer. The API is currently a very rough draft, and there are several functions that were in TAFKAN that are missing in IMAPAdapter (like the folder management stuff to add/edit/delete imap folders) At the moment, IMAPAdapter is pretty much read-only on your 'imap space'. Voila! IMAPAdapter is available in public CVS. Web CVS access will be here soon! (yippee!) -Michel
