[Zope-dev] change in product permissions/behaviour in 2.20b1
The (heavily modified) Survey product from Piers Lauder is in heavy use here. In 2.1.x and in 2.20b1, the links in a folder view point to [objectname]/manage_workspace In 2.1.x, this does the right thing - if you have appropriate permissions on the survey object, you get a management screen. Without 'View management screens' permission, you see a rendered survey form to fill in. Fine. In 2.20b1, this is now broken. No matter what permissions you have, the [objectname]/manage_workspace link turns into a link to [objectname] and you see the survey. I've futzed with __ac_permissions__ = and added that little tip about Globals.default__class_init__(Survey) without any joy. Is this a bug, a deliberate change in behaviour or is it just me? -- Dr Ross Lazarus Associate Professor and Sub-Dean for Information Technology Faculty of Medicine, Room 126A, A27, University of Sydney, Camperdown, NSW 2006, Australia Tel: (+61 2) 93514429 Mobile: +61414872482 Fax: (+61 2) 93516646 Email: [EMAIL PROTECTED] ___ 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] censemble communication toolkit and distributed lock manager
I recently announced the availability of censemble communication toolkit and a distributed lock manager built using it. After reading about ZEO and the plans to turn the Zope Storage Service into a replicated service, I thought you might find this work useful. regards, Mark Hayden CEnsemble Version 0.03 Download: ftp://24.142.58.202/pub/hayden/ CEnsemble is a toolkit for building reliable distributed applications. It provides a library of protocols that can be used for quickly building complex distributed applications. CEnsemble is a rewrite in C of the Ensemble system, which was written in a dialect of the ML programming language. More information of Ensemble can be found at: Homepage: http://www.cs.cornell.edu/Info/Projects/Ensemble/index.html Download: ftp://cs.cornell.edu/pub/ensemble/ Included with censemble-0.03 is a complete distributed lock manager (DLM) built using the toolkit. The DLM can be used either through a text-based pipe interface or linked into your application as a C library. No familiarity with Ensemble is needed to use the DLM (all the interface is in one header file). A DLM tutorial is included (censemble/dlm/README). The DLM features include: * Fault-tolerant. Any of the lock manager processes can fail; the system will remain available as long as a quorum (majority) of the servers continue running. * Load balanced: locks are randomly assigned to servers to manage. As servers are added or removed from the system, they will reassign locks to even the load. * Reader/writer locks. ___ 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 )

No, although we do have a class that we use to wrap around some of the
results that we sometimes return instead of the results themselves.
I'll try taking that out and see if that's the problem.

Here are the contents of 'state':

'SQL Product

We're using ZMySQLDA v1.1.3.

It might be more convenient to update/modify than your cataloging-specific Agent class.

Mixing Session and Cart is not a good idea just because Client >can have several carts, for example. The composition is better than >inheritance in this case, Phillip :-) I look at components in terms of "value add". Your SessionManager's value-add is that it lets you transparently create an instance of something which is associated with a cookie and which can be expired whenever it's idle for greater than a certain period of time. But the idea of a "Session" has no real value-add to me; it just makes it possible for a thing to be managed by the SessionManager. You could in fact do without the Session class altogether, and have SessionManager simply set the lastAccessed attribute directly. This would actually make SessionManager more useful, because you could use it with ZClasses that hadn't been explicitly designed to be session-based, as long as there was an AttributeProvider for lastAccessed. And you could drop the SessionSource class altogether as well, since any RackMountable/DataSkin would be acceptable as a "Session". Popular opinion to the contrary, I don't believe that there is such a thing as a "session" object. Session objects are a hack, to give you a place to put session-specific objects' data. In my opinion, if you can have session-specific objects, you don't really need a "session" object. If one can simply call CurrentCart() or CurrentGame() (where CurrentCart and CurrentGame are SessionManager specialists) to retrieve a session-specific shopping cart or gameboard, why have a "session" object? If I want them both to use the same cookie, I can certainly do that by setting the properties on both CurrentGame and CurrentCart. And there's also no chance that two session-specific objects from different vendors (such as perhaps my Games and Carts) will accidentally collide with each others attributes or sheets in the "session" object, since they're being handled by seperate specialists. >> IMHO, the basicSheet stuff you've done, while convenient, encourages >> developers to take the quick-and-dirty route of just using the Session as a >> place to store variables - and that throws away a lot of the usefulness of >> ZPatterns.

Hmm... I guess the best way is splitting current session >class into two - simple Session and LazySession. Yeah, but to my way of thinking, they *should* be coding them, because if they're not it means they haven't thought their design through enough to know what *kind* of session-specific object they're making. To me, there is no such thing as a session object, only session-specific objects. In any case, it's not a big deal to make a session-specific object. Add a ZClass, base it on DataSkin, set up a "common instance" property sheet, and boom, you're done. Now set your session manager's rack to use it, and you're in business. ___ 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 )

I recommend pdb; there's a How-To klm wrote on the zope.org site called
'Debugging Zope Python Code', that recommends inserting something like
import pdb
pdb.set_trace()
at the part of the code that you want to have it drop down into the
debugger at, and then you can step through and find out the value of
various expressions as you're running things, call functions, etc.
Mr. Creosote is also my favorite - check out the MrCreosote subdirectory
of pcgi/ in your Zope installation; the nice thing about Mr. Creosote is
you can have it send debugging info to another machine (UDP packets)

[Zope-dev] Re: Objet : Re: ZScheduler-0.0.5 problem
This is going to be hard to debug remotely. Can you help me out? First try getting ZScheduler 0.0.6 which fixes a problem of non-responsive Zope, though there the problem was on shut-down not on start-up. Be sure you have STUPID_LOG_FILE working. Then uncomment some of my debugging statements (calls to loggerr) in the source of __init__.py and Dispatcher.py -- maybe add some instrumentation yourself -- all with the goal of observing how far it runs before Zope hangs. Maybe you'll have to activate one of the #import pdb; pdb.set_trace() statements (in an appropriate place, of course). Also, are there any entries in the Zope log or system log that are seem relevant? The only other thing that comes to mind is that ZScheduler depends on Python's threading module, so you must have a version of threading that works on your OS. I don't know whether there are any "gotchas" with respect to Python threading on Linux (Linux 6.1, I386, Zope-2.1.7.). Maybe someone else can step in and let us know if there are.

Think of someone creating a Session subclass called "Shopping Cart", with methods for viewing, checking out, adding/deleting items, etc. Or, if they have many subsystems which want to share the same Session objects, they could do this by having each subsystem use a different propertysheet of the same Session object. IMHO, the basicSheet stuff you've done, while convenient, encourages developers to take the quick-and-dirty route of just using the Session as a place to store variables - and that throws away a lot of the usefulness of ZPatterns. For one thing, you've guaranteed that Sessions have to be stored as persistent objects in the ZODB, or at least that the basicSheet has to support arbitrary properties. * Make dead session removal something that doesn't happen automatically, or at least have an option to do so. Your default deletion algorithm would be very expensive when executed against a non-ZODB database, and would be more efficiently done a few times a day in large batches by a cron job. * Delegate determining which sessions are dead to the Rack, rather than doing it in the Specialist. This allows an SQL implementation to make use of indexes. Specifically, make removeDead call: self._getSource().findIdleSessions(self.session_ttl) And then provide a default implementation of findIdleSessions() in the Specialist. (Btw, please note that your current implementation absolutely requires that at least *some* session data be stored persistently in the ZODB, which if you're using a FileStorage, is a bad place for it to be.) Now, the whole thing works the same way when first installed, but if someone implements the session ID and lastAccessed attributes in an SQL database, they can substitute a different implementation for findIdleSessions() by putting it in the Rack. ___ 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 )

Thank you, Phillip. I've spent all the evening hunting these bugs.
By the way, how do you debug? Is there better way than inserting things
like
print "objectChanging %s, has status=%d" % (
self, self.__dict__.has_key('_v_status_')
)
:-)

We create SQL methods then store them as > properties of the class. This may be what it's choking on. It shouldn't be - SQLMethods don't ever actually assign a StringIO to anything but transient variables. The Results object returned from a query could in some cases wrap a StringIO instance - you don't do anything in your product where Results objects would be stored as object attributes do you? If this were a problem common to all SQLMethod objects then I would expect people to be seeing this error all over the place. Is anyone else seeing this? If you're not storing Results anywhere, it would be helpful to see the str() of the 'state' being dumped in commit() - also to know what database adapter/version you are using...

[Zope-dev] Catalog acquisition problems?
Hi there, We've been experiencing some odd interactions between the ZCatalog and acquisition. Inside the tags things seem to go screwy. It's picking up the properties in the root folder instead of in the subfolder (the context), where the is used. Why would this happen? Another odd thing that happens is that dtml-let variables appeared wiped empty inside the dtml-in: ... ... The will display nothing. 'foo' *does* exist, but it just appears to be empty. Am I missing something, or is this a bug?

I want to use all power of dtml-in and other zope tools. There are things where I can just write my functions and methods; and there are cases so general that it's more correct to extend zope functionality. Do you know that latest version of Zope can sort by multiple keys? How do you extend your ru_sort() to reflect the change?

[Zope-dev] dtml-in: sort is not locale-aware
Hello! Currently dtml-in does not use locale when sorting the sequence. Before creating a patch I want to discuss a way dtml-in should handle this.
