Dear All, I have a Linus Redhat OS with zope server running on it. Firstly, how do I know if zope is using it own python or is using the python that come with the OS. Secondly, which one will give me optimum performance? that is running zope with it own python or with the OS python. And lastly, how do i configure zope to either use it own python or OS python. Thanks and God bless U all. ===== Hamzat kamaldeen Ishola Dnet Systems Limited. 223 Ikorodu Road, Lagos.

Transparent Folder problem on windows
by Shashank Ashtikar 18 Dec '02

18 Dec '02

Hi guys, thnx for ur quick response to my question yesterday. I hv another problem but this time regarding transparent folders. I am using a single transparent folder in the product which contains some dtml and python scripts which I am using frequently in my products Interface. On a linux m/c product works fine but on a windows m/c product runs in to problem with the transparent folder. What I am doing is as follows. I have an instance of product say 'SomeInstance' inside this I have a transparent folder as 'Programs' which is containing dtml and python script files which I need. If I type the path as follows "http://localhost:8080/SomeInstance/scriptname" this works on linux perfectly fine( I use mozilla as well as galeon for managing zope server ) but when I type the same path on a windows m/c using IE 6.0, IE throws an error saying "can not locate "http://localhost:8080/SomeInstance/scriptname" if I modify the path as follows then it works. "http://localhost:8080/SomeInstance/Programs/scriptname" can some one tell me why this is hapening and is there a solution to solve this problem. thnx in advnc Shashank A newbie to zope

API for Zope cacheing
by Felix Ulrich-Oltean 18 Dec '02

18 Dec '02

Is there an API for using Zope's cacheing machinery from python products? Specifically, I have a subclass of SimpleUserFolder which calls 20+ SQL statements every time it's called just to work out the user's details - this is all very cacheable and I can see that Zope provides various caches - there are some useful-looking methods in RAMCacheManager.py, but I was wondering if there is a 'known' way to do it. Thanks, Felix.

ZSQL arguments
by Terry Hancock 18 Dec '02

18 Dec '02

>From the DTML inside of a ZSQL method, is it possible to interrogate the list of arguments? Examing the source, I've tried various combinations of _ context.arguments self._arg self.argument_src argument_src _.argument_src and so on, but nothing seems to be understood. In particular, "_" is defined, but seems to be empty (at least a repr(_) doesn't render anything into the query. It doesn't seem that this information is made available to the DTML code in a ZSQL method. I'm asking because I have a fairly wide table that I want to be able to update on essentially any field with optional arguments. There's nothing equivalent to the <dtml-sqltest ... optional> structure for controlling input, so I'm left with something like: <dtml-if arg1> SET arg1 = <dtml-sqlvar arg1 type="string">, </dtml-if> for a couple dozen arguments, which is sort of tiresome, especially since this would change if the schema changes. It'd be nice to be able to code this as a loop, but it's awkward without being able to handle the arguments as a structure. I can of course do some cut and paste in my editor and solve the problem, but I wondered if there's a more elegant solution.

Permissions question
by Kevin Carlson 18 Dec '02

18 Dec '02

I am searching a catalog based on the following criteria: I have the following folder structure: Root Folder | - Folder 1 | - Folder 2 | - Folder 2.1 | - Folder 2.2 | - Folder 3 | - Catalog I have images in each of the subfolders of the root folder. There is an acl_users folder in root as well as in Folder 2.1. The Catalog contains references to each of the image objects in each folder. If I log in as a user that has access to the Root Folder, all is well. However, when I log in as a user that is listed in the acl_users folder contained in Folder 2.1, catalog searches are getting fouled up. When I search the catalog on a text index and check each object to see if the AUTHENTICATED_USER has the 'View' permission, I am getting several results in the result set that shouldn't appear. Only the images that match the search AND appear in Folder 2.1 should be returned for all the users listed in Folder 2.1's acl_users but I am getting back images in other folders as well. My permissions are set up to allow 'View' access only to 'Authenticated' users. I am searching the catalog with the following python script: -------------------- request = container.REQUEST RESPONSE = request.RESPONSE keywordFields = ('title', 'desc') docList = {} if keyword != None and keyword.strip() != "": for field in keywordFields : for item in context.photoCatalog({field : keyword}) : if request['AUTHENTICATED_USER'].has_permission('View', item) : docList[item.id] = item #convert to list docList = docList.values() return docList ---------------------- The line that calls has_permission is returning 1 for pictures outside of the folder in which the user is defined. However, when I render the results page from the docList variable, the images are correctly shown as inaccessible to this user and the login dialog box is displayed. What I'm trying to do is avoid this login by confining result items to those that are viewable by the currently logged in user. Anyone have any ideas as to why this is happening? Kevin

Getting a Mysqldb.Connection objetct form ZMySAQLDA
by Gilles Lenfant 18 Dec '02

18 Dec '02

Hi, Is it possible to get a MySQLdb.Connection object from a ZMySQLDA object ? I need this because my Python product builds the query string dynamically and a ZSQL Method is not suitable for this. Or should I parse the connection string and build my own Connection object ? Thanks in advance for your help --Gilles

Netscape 4, cookies and domains
by Chris Muldrow 18 Dec '02

18 Dec '02

We're using ZEO to feed two Zope clients and we're using Sessions with a packless storage to keep track of session info. It works great except for one problem related to Netscape 4 that I've seen referenced before in other contexts. I've got browseridmanager set to feed cookies with a domain of .mydomain.com. So www1.mydomain.com and www2.mydomain.com and www.mydomain.com all work fine. But mydomain.com doesn't get a browser ID set. If I take off the domain setting in the browser ID manager, it works with Netscape 4 with mydomain.com but of course doesn't work on any of the other domains and doesn't share domain info across the board. Is there any workaround for this short of forcing them to a www.mydomain.com URL? Thanks! - Chris
