Problem with proxy role...
by Magnus Lie Hetland 07 Aug '00

07 Aug '00

Hi! I'm trying to set up a site with user registration (similar to that on the zope site), and have been using the JobBoard HOWTO as an example of how to let anonymous users add objects. The code works just like it should when I'm logged in as Manager, and I *have* set the proxy role of the method that processes the form to Manager, but still, when I try to use it anonymously, I get the message that I don't have access to the user class... I've tried several implementations, but I don't understand the problem... If the method is proxied as Manager, shouldn't it (and all the methods it calls) have the rights of Manager? (I also tried adding Owner, but that didn't help...) In that case - why doesn't it work, while it *does* work for me when I'm logged in as Manager? Can there be a standard problem hiding here? (Or, perhaps, it's obvious?) Any help is appreciated. Thanks. -- Magnus Lie Hetland (magnus at hetland dot org) "Reality is what refuses to disappear when you stop believing in it" -- Philip K. Dick

Date: Sat, 5 Aug 2000 16:00:29 -0400 charset="iso-8859-1" Zopistas, Maybe I'm making this harder than it needs to be. I want to set up a membership system for the site I am developing with Zope. I do not want to "restrict" any part of the site - instead I want a user to login (at their convenience) and then extend the "menu" options based on their group membership. If a user is not logged in - no problem, they just won't be able to view the advanced options - they'll still be able to surf the site (I want to maintain my user list in an external database as well). What is the best tool in Zope to accomplish this? After searching the site, I find there are several products - ACL Users, GUF, and LoginManager. Is GUF deprecated (The intro tends to give me this feeling)? Is LoginManager the way to go? It also appears GUF is more tailored toward restrictive authentication (I've already perused the "Using GUF with an SQL Database" how-to). I want a user to login (via HTML form/cookie) whenever they like, and get presented with additional menu options (based on their AUTHENICATED/GROUP status). Not have them try to access a "restricted" page (or type "manage") and get a basic authentication login box to get in. As far as LoginManager itself is concerned, I assume it requires ZPatterns. However, the Zpatterns install instructions are *very sparse.* How do I get the thing set up? Here's verbatim from the ZPatterns docs: ----- After unpacking the ZPatterns product, you will need to build this [c] >extension using the included Setup file in the ZPatterns directory. ----- How do I use the "Setup" file?? With the command "python Setup"? It doesn't say *how* to use it. ----- Please follow the standard procedures for building a Python module on your platform. (On Unix-ish systems, this usually consists of copying a Makefile.pre.in to the directory, then doing a make -f Makefile.pre.in boot >followed by make. ----- What are these standard procedures?? I built Python itself with "configure|Make|Make install". Where do I get this "Makefile.pre.in" file in the first place, from my Python src/build directory?? Correct me if I'm wrong, but there's usually some kind of script file to run that get's things going, or a "configure" script. I find none of this in the lib/python/Products/ZPatterns directory after I untarred it. So, I'm basically stumped. It doesn't appear GUF will do what I need, and I have failed on multiple attempts to get Loginmanager/ZPatterns installed. If someone could point me in the right direction on this I sure would appreciate it.

Most of those mails are a year old, is this still an issue? As a developer, do I need to understand threading issues when developing database accessing products, or may I safely assume that threading, locking and transaction semantics are handled between the Database Adapter and Zope itself? I found a mail that says I should run Zope single-threaded when using MySQL: http://lists.zope.org/pipermail/zope/1999-July/006487.html Checking my installation, I find I have no threading option activated, which means I'll be running the default number of 4 threads. What will my server performance look like if I reduce this to 1 thread? Not that I'm having such a wonderful performance now, having my pager go off every hour :-( Is there a way to allocate different threads to different SiteRoot virtual websites, so I can lock a single site in a single thread but let my installation as a whole still retain some multi-threading performance? :*CU# -- *** Guido A.J.

Date: Sun, 6 Aug 2000 16:43:18 +0200 charset="iso-8859-1" Hi! I'm trying to set up a site with user registration (similar to that on the zope site), and have been using the JobBoard HOWTO as an example of how to let anonymous users add objects. The code works just like it should when I'm logged in as Manager, and I *have* set the proxy role of the method that processes the form to Manager, but still, when I try to use it anonymously, I get the message that I don't have access to the user class... I've tried several implementations, but I don't understand the problem... If the method is proxied as Manager, shouldn't it (and all the methods it calls) have the rights of Manager? (I also tried adding Owner, but that didn't help...) In that case - why doesn't it work, while it *does* work for me when I'm logged in as Manager? Can there be a standard problem hiding here?

I knew I'd read it somewhere! First I ran through the help menu, but I must have looked at File/Image Add and missed File/Image Edit. Then I looked at an Image (I had no File objects handy), and when I saw that the help tab for the Edit, page had no description of precondition, and indeed that there was no way to set it, I figured the docs for it must only be in the API section. But the API section does not discuss *any* of the call paramters. So I thought it was undocumented. Since the code supports preconditions on an Image, is this an interface error or a design decision (the latter seems more likely)? If it's a design decision, shouldn't precondition still be documented in the Image api help doc? This is an example of a systematic problem with the (very useful <grin>) help docs as they stand: if the API docs implicitly assume that the parameters are documented in the corresponding management interface panel then there should at least by a cross link; and if there are sometimes parameters that are *not* documented on the manage page, then that needs to be taken into account somehow. --RDM --__--__-- Message: 17 From: Chris McDonough <chrism(a)digicool.com> To: "'Gijs Reulen'" <greulen(a)gilsing.nl>, zope(a)zope.org Subject: RE: [Zope] XMLRPC returns error sometimes Date: Sun, 6 Aug 2000 11:56:35 -0400 Only strings, integers, floats, "booleans", dictionaries, tuples, lists, and special "datetime", base64, and fault objects can be passed via XML-RPC.

The HOWTO seems to indicate that only the regular method must be set to proxy, i.e., "Important:The "entry_addProcessor" must be set to "Manager" proxy for it to work."

ZSQL methods do not pick variables up out of the name space because the possability of unintended collision with database variables is considered too high.

I wonder if you could put your content in a mountable storage and just periodically copy that storage down to the development machine, and similarly periodically copy the master storage (containing the ZClasses) up from the development machine. If your products are Python products you wouldn't even need a mountable storage. > Also, how would you see schema versioning > How could we for instance deal with > objects generated from a product if the product > schema changes ? Zope uses the __setstate__ method for handling this case in Python products. I think there's a howto somewhere but I'm not sure. If not you can find examples of calling it in the Zope sources. For ZClasses the objects get all their info from the ZClass, so you generally don't run into upgrade problems (though people have run into trouble with properties they have tried to delete hanging around on existing instances). --RDM --__--__-- Message: 5 Reply-To: <Steve.Nicholson(a)yoursolutions.com> From: "Steve Nicholson" <Steve.Nicholson(a)yoursolutions.com> To: <zope(a)zope.org> Subject: [Zope] Zope on old hardware??

A Vocabulary allows you to associate an arbitrary method of parsing input text into words for the purposes of cataloging and searching in text indexes.

That happens ... However, during this loop, Zope did not respond to any request. Effectively, it was in single thread mode. Zope 2.1.6 Binary Distribution for Sparc Solaris 2.6 ZOracle DA, DCOracle, Oracle 8.1.6 After several minutes, Zope reported an "infinite recursion in document template" and the world awoke from its sleep. I was unable to reproduce this at home, though: Zope 2.1.6 Source Distribution on Linux 2 No database connections. Hugh, I have been lying: I just removed the "-D" from the Linux start script, and Zope blocked during the infinite loop. The behaviour is not related to the "-D" set or unset.

SQL query template: .... <dtml-sqlvar "_[name]" type=string> .... reported: "missing input variable: _[name]" Of cause, I did not expect that such an input variable should be necessary and I suspected the DTML parser not to see the "..." around "_[name]". After analysis, the explanation was simple: SQLVar.render is a bit stupid in its error handling: try: expr=self.expr if type(expr) is type(''): v=md[expr] else: v=expr(md) except: if args.has_key('optional') and args['optional']: return 'null' raise 'Missing Input', 'Missing input variable, <em>%s</em>' % name This error handling is only senseful for "type(expr) == type('')", i.e. for plain variable access. For true expressions, the original exception would be *much* more useful. In my case, unwrapping the "try ... except ..." produced "KeyError: FOLLUP_UP", an obvious type (FOLLOW_UP rather than FOLLUP_UP). Thus, the above exception handling should become: except: if args.has_key('optional') and args['optional']: return 'null' if type(self.expr) != type(''): raise raise 'Missing Input', 'Missing input variable, <em>%s</em>' % name I will put it into the collector.

Someone else already told you, that you must create a parameterless method (it need not necessary be named "PrincipiaSearchSource") that returns the files content. You may not need to keep the rendered version around but may be able to extract the plain text on demand. I think, there is a "word.dll" that provides access to MS Word from applications.

In the Squishdot Product I discovered this: Readme = Document('', __name__='') Readme.__roles__ = None This one seems to add a README tab.

Thanks, but I'm really interested in how I would add other objects.

Organization: Net Facilities Group *** http://www.nfg.nl From: gyst(a)nfg.nl (Guido A.J. Stevens) Date: 05 Aug 2000 14:22:30 +0200 I'm hunting down an arcane problem in one of our Zope sites and find myself hitting new and wildly diverse problems every day. I hope somebody can point me in the direction of some solution strategies. Main suspect is a corrupted Data.fs.in file. How can I audit and repair it? problem A: access denied vs. KeyError ============================ For starters, we built a website with a lot of custom programming. I created the NFGnav product http://www.zope.org/Members/gyst/NFGnav and my partner built a collection of ZClasses. All this was Tested And Working Fine (TM). Since some weeks, part of the site gives an 'access denied' error. We had to shut down that subtree. Strange thing is, it also gives access denied for the manager/owner logins of the site - that's me and I really have access to everything. What is even stranger, is that when I logon as superuser, I get a KeyError instead of an access denied error. => Question: which parts of zope would be prone to denying access to a privileged user, while generating KeyErrors for the superuser? problem B: hanging zope thread zombies all zope sites ======================================== While debugging this problem, I found a strange correlation with another problem we're having: zope threads consuming 99.9% CPU. Now and again, a zope thread hangs. All zope sites are dead. I have to not only restart zope; I have to stop zope, restart apache, and start zope again to get rid of the hanging thread and get the zope sites alive again. As soon as I start digging around in the buggy site, the number of thread crashes jumps up. In combination with the problems we're having with that site itself, this suggests two possible causes: 1) ZODB curruption. We've had a complete server crash 3 weeks ago and it is quite possible the ZODB isn't 100% healthy. In my zope installation I found a utility 'bbb.py' to audit data storage files. Alas, it is of no use: | zeno:/usr/lib/zope/utilities# python bbb.py /var/lib/zope/import/www.intratuin.nl.zexp | | The input file is not a ZODB 2 database file. | This script only works with ZODB 2 (BoboPOS) data or export files. => Question: is there another utility for checking and repairing object stores? 2) Another possible cause would be an infinite loop in one of our custom scripts. To try and debug this I wanted to import a copy of the offending site into one of our testlab machines. However, on importing the zexp file I got: <STRONG>Error Type: TypeError</STRONG><BR> <STRONG>Error Value: ('len() of unsized object', <class Shared.DC.ZRDB.DA.SQL at 845bd28>, None)</STRONG><BR> <!-- Traceback (innermost last): File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/lib/zope/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/lib/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_importObject) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_importObject) File /usr/lib/zope/lib/python/OFS/ObjectManager.py, line 478, in manage_importObject (Object: ApplicationDefaultPermissions) File /usr/lib/zope/lib/python/ZODB/ExportImport.py, line 284, in importFile TypeError: (see above) I get the same error if I export another part of our production zope installation and try to import it to another test machine. Which points back into the direction of a file corruption again, doesn't it? => So, what can I do about it? :*CU# -- *** Guido A.J.

I am new to using Zope, but have been succesfull at using a psql input wizard to generate forms to dump data to a postgresql table. However, I have a dilema. I would like to generate a form that can dump multiple inserts to a variable, say x1 into a table. However, there is an additional variable, x2 that would have to be only entered once and would be the same for every record for which a different x1 is entered. I would like the user to enter up to 50 records for x1. Looking at dtml syntax it seems the <dtml-in> should do this. Could anyone point me to any examples or provide some help?
