[Zope-dev] ZODB optimization
I'm wondering, is the ZODB easily 'fragmented' or .. un-optimized ? If so, are there any tools/functions that will 'unfragment' / optimize it? Does the 'pack database' in the Administration menu do this? If so, it could be a Good Thing (tm) to have separate optimize and packing (history deletion etc.) functions (buttons). Is there any way to make an object not keep history on itself or on contained objects ? -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 )
Re: [Zope-dev] Mail and zope
> Is there anyway to get a hold off the message-id of e-mail sent through > the sendmail tag? As far as I can see, there isn't any generation of a message-id in the MailHost product. If you want to get a hold of the message-id, the right thing would probably be to generate it yourself, and adding it in the header field of the message you're sending.. I.e., something like this (untested): To: From: [EMAIL PROTECTED] Message-ID: Although using a message-id generated from one of the python library modules would be a better way of doing it..

Hi guys,
Does anyone know how to disable acqusition ?
That is, with a simple method, and not disabling the Acqusition class,
something like self.aq_disabled('attribute') .
Thanks.

[Zope-dev] Implementing a URL path resolver
Hi guys,
I've been tinkling with a function that does what REQUEST.resolve_url does,
except without it relying on having a REQUEST instance available.
That is, just resolving the path itself, something like this:
path ÿstring.split(relative_url, '/')
path ÿfilter(None, path)
new_path ÿ'%s' % path[0]
path ÿpath[1:]
for element in path:
new_path ÿnew_path + "['%s']" % element
return eval("self%s" % new_path)
Now, neither []- or .-like evaluation of the path works..
Any ideas?
Cheers,
Morten

[Zope-dev] Sessions, ConflictError and emails
Hi, I have a site which is based on Zope and Plone, where users can shop around (shopping cart is stored in SESSION objects) and a separate part of the site (backend, Plone) where newsletters and such can be sent out. I have a problem however with duplicate emails being sent out to the subscribers, and this is most likely due to conflict errors being raised.. The event.log file says: 2008-02-18T21:05:23 INFO ZPublisher.Conflict ConflictError at /VirtualHostBase/http/www.site:80/VirtualHostRoot/levanger/plone/site_newsletter/nyhetsbrev-130208/testSendToMe: database conflict error (oid 0x92aa, class BTrees._OOBTree.OOBTree, serial this txn started with 0x0373d8eef99cf5bb 2008-02-18 21:02:58.503076, serial currently committed 0x0373d8f1624479aa 2008-02-18 21:05:23.031441) (58 conflicts (0 unresolved) since startup at Thu Jan 24 17:34:08 2008) Now, those errors aren't a big deal in themselves, but it is a problem when the system sends out duplicate mail messages to lots of visitors. I've seen some blurbs about deferring sending emails until the transaction has been completed, and I just discovered zope.sendmail which is said to defer sending emails until the transaction has succeeded. Is zope.sendmail a good choice? Will it work with Zope 2.9.8?

| "current object"? You probably mean objects?
No, the current (containing) object.
| Couldn't you do that with getParentNode().id?
Then I'd get the parent of the current object, wouldn't I?
An example to elaborate:
ZOPE
tmp
folder_a
folder_b
item_a
Now, if I'm in the context of tmp, I'd like to have a method that will
return this list:
['tmp',
['folder_a',[]],
['folder_b',[
'item_a',[]]
]
]
Anyhow, I got a tip to read the ZDOM.py file.. thanks. =)

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).

[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.

[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
manage_add_b
(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] 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] 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] 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've also seen several people (including guys from DC) refer to ZClass products as (paraphrasing) not-so-good and half-baked..

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.

I'm not sure whether the code above is thread safe or not. ThreadSafeCounter was made because I don't know enough about Zope internals to determine whether or not the counter would return unique values, nor do I know enough about threads to be completely sure that it would, every time. File locking is a simple concept, and easy to understand. As I've understood it, two threads serving requests have a copy each of the database, and only when changes are committed are they reflected in the database. Therefore, two requests created at the same time could get an identical copy and therefore and identical value. ..so, it basically boils down to the fact that it's simple to use file locking.

[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] 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] ZCatalog hackery
Hi guys, I've got a problem with ZCatalog. I've got plenty of large objects, ranging from 100KB to 100MB in size. Needless to say, these take up a lot of processor time when indexed by the ZCatalog. Now, these object have to be moved from time to time, only moved, so that one or two of the related columns and indexes are affected (the path and the parent container id); is there a way to go around this so that those two, the one column and the index are updated, and not, let's say the indexed body (which is 100KB - 100MB in size) ?

[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?

[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!)

('type', 0, , ): (see above)
I added an extra try except block:
if request.has_key(index.id) :
try:
if len(request[index.id])>0:
r=index._apply_index(request)
except:
raise str((index.id, request[index.id],
type(index.id), type(request[index.id])))
The original exception was a TypeError, len() of unsized object.
Cheers,

Cool. And maybe some apt-get functionality?

[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. Some interesting articles, food for thought: http://www.zdnet.com/enterprise/stories/main/0,10228,2777053,00.html http://www.gnu.org/philosophy/license-list.html#GPLIncompatibleLicenses http://www.gnu.org/philosophy/bsd.html [1] http://www.thingamy.com/tpl Regards, 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 )

Because that is what I understand you to say. Others have > said the opposite. Yes, you can distribute a GPL-compatible licensed code with GPL licensed code without licencing the former under GPL. Take a look in the Linux-kernel source tree for example. And yes, it would be very interesting to see the underlying reason(s) for the ZPL..

Verifying the license with the GNU people now. -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 )
