[Zope-dev] Re: [Zope] Restricting URL access to objects that are not complete web pages
Stephen Simmons wrote: My thoughts were to use an html_header that tracks how deeply components are nested so that inner components turn off the page wrapper. This achieves 1 and 2. This also achieves 3 if sections raise an exception if their page wrapper is not turned off. You only want to see standard_html_footer and so forth when REQUEST.steps[-1]!=fragment_id, so it would not be accessible directly by URL. Try something like this for standard_html_footer: dtml-if "REQUEST.steps[-1]=='standard_html_footer'" dtml-raise type="NotFound"/dtml-raise/dtml-if /BODY/HTML I think using siteaccess for this is more elegant, though. All the knowledge about what is allowed and what is not is maintained in one place, and the knowledge can be declared flexibly using regular expressions. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
RE: [Zope-dev] acl_users
In AccessControl/User.py, acl_users is used as the name of user folder objects in their classes, and in the constructor, code checks for an existing "acl_users" object to prevent dual-adding user folders. This could be changed to check whether __allow_groups__ has an id, and then checking whether that 'id' exists. I've read through all the Zope source that uses __allow_groups__, so I think I know what it is used for. What I can't work out is, why is this value called __allow_groups__ ? Can anyone offer any insight? Long ago, when the sky was dark and the earth boiled and the primordial elements of Zope were brewing, __allow_groups__ was a simple dictionary-like thing that was generally hard-coded in applications to control access (and the publisher used it directly). As the earth cooled and simple life began to emerge, the __allow_groups__ structures became manageable through the web in a relatively rudimentary way (but still looked a lot like simple dicts to the publisher). By the time the hairy mammals began walking upright and Zope assumed the general form we see today, the publisher expected __allow_groups__ to be either a dict-like object or to have a 'validate' method. In theory, it still supports the old dict behavior today. Maybe not insight, but a little history at least... 8^) Brian Lloyd[EMAIL PROTECTED] Software Engineer 540.371.6909 Digital Creations http://www.digicool.com ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] using a DA
Hi,
i have a problem on using a DA in my Product.
I have a Postgresql DA in my root-folder. If my Product is installed
in the root-folder and i use:
self.con_obj = DA.DA('id','','pgsql','',query)
return self.con_obj()
When i install my Product in a sub-folder of the root-folder and i call
the function above the following error occurs.
The database connection pgsql cannot be found.
Who can help me, please

If I have to define __cmp__ and __hash__ then I will basically be making
them up because the object in question are mutable - except for their
identity.
I don't think that in this case __cmp__ has to be implemented; you just
use the default behaviour of object identity comparison. All you need to
do is then implent a __hash__() method that will return a 32-bit integer
that is unique to the object. You could base this on repr(self).
Why do the Python class instances naturally act as dictionary keys while
the ExtensionClass instances don't?
ExtensionClasses pretend to be Python classes, but are not succeeding
everywhere. I am not that deeply knowledgable about Extension Classes, so
I cannot tell you why exactly you see this difference.

You cant do that with todays Wikis, which need to capture the whole discussion right from the beginning (IMO) [snip] I think you could integrate both mailinglists and wikis. On the one hand, often we'd like to preserve a good posting in a mailing list as a wiki page. So we make a separate [EMAIL PROTECTED] address that's subscribed to the mailing list, that keeps listening to the list and sees things like this in postings: Wiki:StructuredTextWiki:FooBarPage This is a bunch of text that should be added to FooBarPage. Wiki:end Or I see you posted something interesting, and *I* think it should be on the list: Wiki:StructuredTextWiki:FooBarPage Something very interesting you wrote Wiki:end It should strip off the quotes automatically in such a case. Some care should be taken so that replies don't add the same text to the wiki *again*. Anyway, so that's the mailinglist to wiki gateway. Now the wiki to mailinglist gateway. There's a very interesting discussion going on about ZFoobar on the MetaSyntaxWiki. So, someone presses the 'make this page into a discussion list' button, and the following happens: * A new mailinglist is created (with some name the user could fill in) * the wiki page is posted to the mailing list as the first message (perhaps after some editing) * if there is a notification system, the existence of the mailinglist is announced (ideally to all people who posted on that page). * the mailinglist is also listed in some central list somewhere on the Zope site. As people post interesting things to the mailing list, the wiki can be informed by the mechanism I described above. There should also be a rule for the list to be shut down as soon as the discussion has died down (no postings for a while, etc). I hope these ideas contribute to the discussion. I too find it harder to keep track of wikis than of a mailing list, and editing structured text in textareas through the web is not very unpleasant. I keep tripping up over structured text rules as well. (that gives me an idea that is fairly simple to implement: [EMAIL PROTECTED] is an address you can mail to directly as well, and whatever you write is added to the wiki page you indicate; we get to use our own editors, parts can be forwarded from the list, and so on) Regards, Martijn ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope-dev] adding local roles to folders within a Product
I have a ZClass-based product. The folder (should I be calling this an Application Object? :-) ) that contains all the product methods and objects that are accessible via the web has some local roles defined on it. I'm making a sort of Wizard to instantiate a new application instance. This happens by copying an empty application folder from within the ZClass product, to a chosen place in the standard part of the ZODB object heirarchy. I want to define the local roles on the "prototype" folder that is inside my Product. However, when I go to Control_Panel/Products/MyProduct/prototype/manage_access, I get the "map permissions to permissions" screen, rather than the "map permissions to roles, and define local roles" screen. Can I define local roles on my prototype folder -- perhaps using an external method, or DTML API calls to do it? Or, is there some reason that local roles don't make sense within products, and so I have to copy my prototype folder to elsewhere in the ZODB, and then set the local roles? -- Steve Alexander Software Enigineer Cat-Box limited http://www.cat-box.net ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

In a Zope binary install, Python 1.5.2 is included; it's library files are

Any clues to what is wrng here?
From the source of smtplib.py:
""" SMTP 'ehlo' command.

smtpib first tries to send a 'EHLO' command to see if the server supports
extended SMTP commands. But it will have to send the hostname of the
machine from which you are contacting the SMTP server along. This is where
things go wrong (line 303):
name=socket.gethostbyaddr(socket.gethostname())[0]
The above line _should_ return your Fully Qualified Domain Name. But the
result of socket.gethostname() isn't resolvable into a full host
specification; thus resulting in the 'host not found' message.
I *think* that socket.gethostname() returns exactly the same result as
'hostname' on the commandline does. You may want to check that in a python
interpreter (pythonCR import socketCR socket.gethostname()CR).
You can use the same command (hostname) as root to set the correct
hostname, or you will have to make sure your hostname is resolvable into
an ip-address (edit /etc/hosts should do that I think).
To illustrate, the output of the command
socket.gethostbyaddr(socket.gethostname()) on my machine results in:
('localhost', ['sneek'], ['127.0.0.1'])
which matches nicely with the following entry in /etc/hosts:
127.0.0.1 localhost sneek
Hope this helps.

If number(b)number(a) then sorting-by-index works well. This might happen for example if you are sorting by "author name", where there are more matches than there are authors. This is efficient since the catalog precomputes the matches grouped by author name, and it only needs to sort the groups. If number(a)number(b) then there is no sorting-by-index. In this case there are more groups than matches (ie many groups are empty) and it is more efficient to sort matches.

[Zope] Import class in External method
Hi, I had some weeks ago a nice discussion on " Howto import external class in an external method ". However, I use now the " http://www.zope.org/Members/4am/instancehome " method to run my site. This really cool ;) In these condition, I would like to use something similar to import modules. If I want import a class placed in **my Zope root** tree the question is : where to place this module to import it ? I put my module in " MyZopeRoot/Products/Foo/ " and the call in the external method is " from Foo.mymodule import * " or " import Foo.mymodule " but nothing works. I stress I have also created a __init__.py in " MyZopeRoot/Products/Foo/ " but nothing has changed.

RE: [Zope] Clean Zope source patch
I need to patch Zope source code to make an I18N module of my own work. The function I need to patch is Publish.py in lib/python/ZPublisher (only the publish function). I'd like to to it a 'clean' way, that is, without modifying the actual source code. To achieve this, I can copy the publish function into MyPublish.py, patch it, and, somewhere in the Zope source file hierarchy, put something the following statement : ZPublisher.publish = MyPublish Well, huh... This is theory. It doesn't work because I don't know where ZPublisher is actually imported into Zope, and, thus, where my affectation will really take effect. Does anyone knows how to do this ? Or perhaps someone knows a better way to "cleanly" patch Zope source ?. An ideal way to do "guerilla patching" like this is with a Product. This is in fact how HotFix products work. At Zope startup time, the Zope machinery tries to import each package in lib/python/Products. So you can create your own "product" which is nothing more than a package with an "__init__.py" that performs the replacement. For example, create a directory "I18NHack" in your lib/python/Products and a file therein "__init__.py" (along with your MyPublish module). The __init__.py would look something like: from MyPublish import publish import ZPublisher.Publish # replace the original publish function... ZPublisher.Publish.publish=publish This way you don't modify any Zope source and can pretty easily manage and distribute your patch. Hope this helps!

Re: [Zope] Restricting URL access to objects that are not complete web pages
Steve, Ideally the publishability of an object would be an internal property of that object, not something that is set externally via rules in SiteAccess. It's been a little while since I last looked at SiteAccess, but wouldn't using SiteAccess force you to store publishable objects in one part of the database hierarchy and non-publishables in another? If you wanted publishables and non-publishables all mixed up in the same folders, SiteAccess's rules might get a bit complicated. Another approach could be to: - create a folder that does a RESPONSE.setStatus(404) as the URL traversal machinery passes it. This sets up the default condition of 'NotFound' error for the URL - at the end of the URL, if the final object is publishable or the final item is a publishable method called on a publishable object, do a RESPONSE.setStatus(200) to say 'OK'. Would this be feasible without hacking HTTPResponse.py too much?

Even if you don't reset the status to 200 and it remains as 404, the page will still get sent to the browser. You don't want to mess with the traversal machinery on this, as you want traversal to continue to work as it does now. I think your intent is to block direct requests from a web-browser for particular objects. The easiest way of doing this is to check REQUEST.steps[-1] to see if it equals the current object's id.

Using versions to isolate development from current users is useful but only in a limited fashion. Most environments don't allow development on production servers, and if you're doing serious development you're probably working on the filesystem (at least partially) anyway. We're facing this challenge at ZapMedia, and I had the same problem at WebMD. The solution there was a bit easier because we had fewer developers working on more isolated projects.
