[Zope-dev] Debugging spinning Zope?
Hi, I have a problem with a Zope that hangs eating up 99.9% of the CPU. I've tried to debug the problem by using DeadlockDebugger but that doesn't even return when accessing it. I guess the next step is to use pdb og gdb - are there perhaps any documents out there describing the process?

[Zope-dev] New ways of getting transactions?
Hi, I'm having some code that bombs out trying to commit a transaction; I believe it's because of new ways of doing things in Zope 2.9.. how do you call the equivalents of get_transaction().commit() and abort() in Zope 2.9? Will those new ways work with Zope 2.7/2.8? Thanks. -- Morten W.

[Zope-dev] Problems adding many objects
Hi, I've created a script that imports XML into the ZODB, using regular TTW methods - and all is fine, except for when I import large files, with many objects. After about 288 objects, the import fails when the method that adds an object in the ZODB returns None, instead of the object it added. From what I can tell, the added object is not None before it is returned, but the name object, set via the expression object = self.manage_add_issue(...) is None. So it looks like somewhere between 'return issue_' in manage_add_issue and the expression above, the object is lost. Any ideas what could be happening here? I've managed to work around it for now, but it is interesting nonetheless.

With source files, it's easier to 'see'; not to mention that code can be factored out into generic python modules in a less cumbersome way. How about meta-programming (designing) via the Zope interface, with UML or somesuch; automatically generating Python code, then enable designers to use a ZFormulator-ish product to edit the interface while a programmer can work on the 'backend' (emacs on a terminal)? One thing I'd really like to implement is DTMLFile transparency via the web, so that a designer could enter into Control_Panel/Products/MyProduct and edit webinterface files there, reflecting it on the filesystem. ZClasses (as they are today, 'half-baked') should be tossed out, and focus brought on making one approach easier. -Morten ___ 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 )

That is a hard question. I don't know whether Zope is just an interpreter or contains facilities that, in effect, the user program links with. It makes a difference. If the former, you can run programs on Zope regardless of their licenses. If the latter, then in general, you can't take someone's GPL-covered code and combine it with Zope, because the Zope license is GPL-incompatible. If someone wrote a GPL-covered program specifically for Zope, you are pretty safe taking that as implicit permission to combine it with Zope.

[Zope-dev] ZPL and GPL licensing issues
Hi there, we @ thingamy are considering changing our license to a ZPL-ish one [1] to better serve our clients' needs. However, some of the (Zope) products we've developed may need to rely on GPL'ed code, or needs to be incorporated within it, and the 'obnoxious advertising clause' seemingly puts a stop to it.. The ZPL is listed as a license incompatible with the GPL, but it doesn't really say clearly what the reason is, as far as we can figure, it's because of the advertising clause. Anyways, I'm wondering if any of you have encountered the same issue developing Zope products and any solutions towards it.

[Zope-dev] Non-undoable storage
Hia guys, during testing of a mail product I've discovered that the Data.fs file may bloat considerably after storing 50 messages. Packing the database will reduce the Data.fs file to 20 MB (from 40 MB). Another thing is that storing 50 messages takes a *long time* on a 600Mhz 256 MB RAM system. The thing that struck me was that transactions may cause a lot of overhead, both in database size and for execution speed, so, the thing I'm wondering about is if there exists a non-undoable storage, or something similar that doesn't support transactions.. Another thing I noticed BTW, is that retrieving 500 messages and packing the database on every 50th message (all messages retrieved during one request) would lead to off the charts memory usage, the process ended up using 700 MB of RAM (had to add swap files as the footprint grew!)

[Zope-dev] ZCatalog features
Hia guys, A couple of comments and questions about the ZCatalog: Is it possible to pass an argument to the catalog so that returned brains would instead be actual objects? Given that we have to manually join search results, because ZCatalog doesn't support ORs etc (for FieldIndexes), wouldn't it be useful to have some sort of tool that could take a set of results, and return a result with only unique values?

[Zope-dev] Ensuring 'freshness' of dynamic pages (slightly offtopic)
Hi guys, I've been trying to ensure that documents from a certain website are always fresh, that is, every request for a new page must be validated before the client sees it. I've tried using these HTTP Cache-control directives: no-cache no-store max-age (1) must-revalidate but no such luck. If I for example specify 'Check against server: Never' in IE, the pages are cached, no matter what. Is it possible to ensure that pages are always fresh, even if it is specified on the client side that the client should never try to retrieve a 'fresher' page? I've been contemplating a new solution, which is to append a string like ?ensure_freshness=02349025180.12 (some random, unique id) on each link, but that's not a thing which I wish to do now, at such a late stage in the project. Also, it strikes me that it isn't possible to specify multiple cache-control directives with the current HTTPRequest implementation, am I missing something here, or is this a bug / missing feature? Any ideas?

[Zope-dev] Storing lots of big objects in containers
Hi guys, A product I'm currently developing has a rather big (in many ways) problem. A product instance may store many, (thousands) of big objects, ranging from 1-50 MB in size. Now, whenever the product instance is accessed, with say for example 100 objects with a size of 2MB each, Zope slows down to a crawl, and spends a lot of time loading (I assume) the objects from the ZODB, even though only 10 objects are actually accessed. ..I can't really use any external storages, as the reason for bringing these objects into the ZODB was to structure them and make then indexable by ZCatalog. And there's probably no time for ZPatterns. Someone suggested using BTreeFolder, but the documentation and examples for it are rather scarce. Does anyone know of products that make a good example use of BTreeFolder? Would BTreeFolder work for this? Are there better alternatives?

[Zope-dev] ConflictErrors and how to handle them
Hi guys, I've been struggling with a problem, namely ConflictErrors. At times, a long-running process may add 100, 1000, 1 objects to a single folder. Under this process, several ConflictErrors may be raised, but they are captured, and the transaction committed again. Problem solved. However, the other side of the problem is that regular requests, from other users, may be be aborted, and as a result the user is presented with a Zope Error screen, which says ConflictError. If I've understood this correctly, it is because the ZODB connection is hosed, and innocent reads trigger ConflictErrors. So, I'm wondering about turning up the number of Exceptions each request may handle (it's 3 now, right?) and just hope that the exception isn't raised more than 10-20 times. Where can I increase the number of accepted exceptions per request? Any thoughts on the solution itself?

[Zope-dev] ZClasses vs. Python Products
Hi peeps, I'm trying to figure out whether to continue work on an existing ZClass product, or rewrite it from scratch. I get a claustrophobic feeling working with ZClasses, and using Python products is more intuitive to me.. I've also seen several people (including guys from DC) refer to ZClass products as (paraphrasing) not-so-good and half-baked.. Anyways, would you care to help me list the pros and cons for ZClasses and Python products? The greatest features of ZClasses are, AFAICS: TTW editing, very good for interface designers Rapid prototyping Easiliy transferable products (If you think there's anything missing from that very short list, please share your thoughts..) And the greatest features of Python products is: Full control of *everything* Now, rapid prototyping in Python products can be achieved using products like mkzprod[1]. And, if there could be some facility to edit all DTML and image files related to a Python product TTW, (and maybe be able to 'subclass' or override these on a per product instance basis), I can't see any *good* reason to develop products with ZClasses. [1] mkzprod: http://www.zope.org/Members/eenge/mk-zprod Hoping for a good discussion.. Cheers, Morten BTW: I've basically made up my mind, and it'll be Python products.

[Zope-dev] LoginManager and ZPatterns
Hi fellow zopers,
I don't know if it's a bug or feature, but whenever I try
to access parental objects from a user object in python
code, I can't seem to find anything.
That is, whenever I call acl_users.getItem('user123').getParentNode()
(the acl_users is a LoginManager instance) it returns None. But,
if it's called from DTML, with exactly the same expression, it returns
the containing object...
Could someone shed some light on this?
Thank you.

[Zope-dev] How to avoid ConflictErrors ?
Hi zopers, I'm having problems with a product I'm developing. The product is part of the ZopeGUM package, the GUM product. If you have a look in gum.py in that product, you can see a method named _retrieve_messages, which can at times store enourmous amounts of objects and data in one transaction. Now, if I access the GUM instance at the same time as this method is being called, I may either get a ConflictError raised in the page, or in the Zope debug output. I've read all the posts I could find regarding ConflictErrors, and they mention that careful programming could help in avoiding these exceptions. I'm assuming that this applies only to whenever two threads are trying to *modify* the same object; and frankly, I can't see where I'm modifying any objects, unless modifying one object, an rfc822_message instance in a message_container instance also somehow modifies the message_container. Any idea what I'm doing wrong?

[Zope-dev] AttributeError when adding ZClass product (PortalMembership)
Hi guys,
I have a problem with a product. This product, let's call it product
SuperSecret, adds a number of folderish objects to the new instance
when it is created. Now, if we name the SuperSecret product instance for
a, and the class instance that raises the AttributeError b, I
will show you what happens:
I am at the root folder of the Zope instace, and select the SuperSecret
entry from the Products list. There I enter the relevant information,
and submit the form. But then, the SuperProduct raises an exception
when the manage_add_some_class function tries to add the new b instance
to the a instance. (No exception is raised when the offending line
which tries to access the Control_Panel via the b instance & acquisition
is commented out).
The manage method, which looks like this:
def manage_add_b(self, id, description, REQUEST=None):
"Add an instance of the b class."
self._setObject(id, b(id, description))
#get_transaction().commit()
Shared.utils.install_authentication_folder(self[id])
which calls an external function, which looks like this:
def install_authentication_folder(container):
container.Control_Panel.Products.PortalMembership.doInstall(folder=container,
REQUEST={})
which raises an AttributeError that looks like this:
Zope Error
Zope has encountered an error while publishing this resource.
Error Type: AttributeError
Error Value: Control_Panel
[...]
File /home/morten/Zope/lib/python/Products/rs/rs.py, line 56, in manage_add_a
File /home/morten/Zope/lib/python/Products/SuperSecret/a.py, line 168, in
__init__
(Object: CatalogAware)
File /home/morten/Zope/lib/python/Products/SuperSecret/b.py, line 61, in

(Object: CatalogAware)
File /home/morten/Zope/lib/python/Products/SuperSecret/Shared/utils.py, line
211, in install_authentication_folder
(Object: CatalogAware)
AttributeError: (see above)
Now, I guess this could be because the new instance isn't aware of it's
surroundings, but I've tried to manually commit the transaction (which
could help?), but obviously didn't... =)
I guess it could be a solution to call a number of methods after the
product instance is added, but that's a bit too hackish for me.
Any ideas?
Thanks in advance,
Morten

[Zope-dev] Calling HTMLFiles
Hi,
I'm having difficulties calling an HTML file from python..
Here's the code:
[...]
from events import conflicting_events
calendar_event_add_redirect = HTMLFile('calendar_event_add_redirect',
globals())
manage_add_calendar_event_form = HTMLFile('calendar_event_add', globals())
conflicting_events_dialogue = HTMLFile('calendar_event_conflicting_events_dialogue',
globals())
# These two expand into seconds
expand_hour = lambda x: x * 60 * 60
expand_minute = lambda x: x * 60
def manage_add_calendar_event(self, title='', note='',
alarm=0, start=0, end=0,
priority=0, status=0,
REQUEST=None, RESPONSE=None):
"Add an instance of the calendar_event class."
new_id = str(self.get_unique_id())
if REQUEST:
alarm = expand_hour(REQUEST['alarm_hour']) + \
expand_minute(REQUEST['alarm_minute'])
start = expand_hour(REQUEST['start_hour']) + \
expand_minute(REQUEST['start_minute'])
end = expand_hour(REQUEST['end_hour']) + \
expand_minute(REQUEST['end_minute'])
title = REQUEST['title']
note = REQUEST['note']
priority = REQUEST['priority']
status = REQUEST['status']
conflicting_events_ = self.check_timespan(
self.getParentNode().getParentNode().id,
self.getParentNode().id, self.id,
start, end)
if conflicting_events_:
return conflicting_events_dialogue(self, REQUEST)
[...]
Now, if there are any conflicting events, the HTMLFile is returned, with
some parameters passed along.
What I'm wondering about is how can I pass the variables defined
in the REQUEST so that they can be looked up with dtml-code in
the conflicting_events_dialogue?
And doing it without raising KeyErrors on DTMLMethod that are
called from within the conflicting_events_dialogue?
Thanks.

Re: [Zope-dev] ZCatalog and 'fuzzy logic'
> I do not think that "fuzzy logic" is strongly related to "regexp-like". > Anyway. > > Fuzzy searching often means "finding matches with characters omitted, > replaced or inserted". It seems I misunderstood the term fuzzy logic myself. Fuzzy logic means if I search for a word, for example 'programmer', it will return matches to the words 'program', 'programming','programmable' etc. I.e., it will somewhat intelligently return words that are similar in what they mean, using grammar rules (chopping off endings of words and making them match others).

Well, to try to explain the problem: If I have 1.000.000 objects catalogued, all of the meta type Person, and I want to find all the instances matching the regexp-pattern '?Peter' on those objects' attribute firstname, and the regexp-pattern '???ne' on that objects' attribute lastname, how could I effectively implement that?

[Zope-dev] LoginManager and PTK
Hi guys, I previously posted a couple of functions that enables users to login at a lower level in the tree-structre than where the actual user folder is. I.e., a user could enter username and password at /a and get redirected to /a/a/a/a/b (the acl_users folder would be located in /a/a/a/a). Now, there is a minor problem, because I can't seem to figure out how to login the user to the actual context /a/a/a/a, except maybe first redirecting the user to /a/a/a/a and then letting the user log in from there..
