[BUG] maybe yet unknown BTREES bug
by Dieter Maurer 28 Jan '03

28 Jan '03

Attention: cross post We have run in an apparent "BTrees" bug (with the "BTrees" version included in Zope 2.5.1). We try to insert a value into an "BTrees.OOBTree.OOBTree" instance with tree[k]= v and get an "exceptions.KeyError on 13384379A0pfvqTmtEQ". The code comes from Zope's "Transience" implementation. The reported key is some session key. We are not yet sure, however, whether it is the key we are just trying to insert. Reading the "News.txt" of ZODB-3.2a1, this bug may not yet be known. We will install the "BTrees" package from ZODB-3.2a1 and see whether the problem disappears. I will report back... Dieter

2.6.1b2?
by Leonardo Rochael Almeida 28 Jan '03

28 Jan '03

Hi, I'd just like to know when can we expect a 2.6.1b2. It would be nice to have a new release where we don't have to patch just to get ZClasses to work. -- Ideas don't stay in some minds very long because they don't like solitary confinement.

Zope 2.6.0 ZMI Problem for CJK(Collector 623) patch.
by Hajime Nakagami 28 Jan '03

28 Jan '03

Hi ! Zope 2.6.0 have a problem for non 'iso-8859-1' user. And Collector 623 is still incollect now. http://collector.zope.org/Zope/623 It's serious problem for CJK(I'm Japanese). So I make patch for 2.6.0. http://www005.upp.so-net.ne.jp/zope260-i18n-20021123.diff 1.Install $ cd $(INST_HOME) $ patch -p0 <zope260-i18n-20021123.diff 2.Usage Set attribute 'default_charset'(string type) as 'foo' some Folder object. And after you can set 'foo' charset in the Folder object via ZMI. 3.Attension Python need to recognize 'foo' encoding. (You need install adaptable Codec) I try with 'euc-jp' charset, and I think any charset is available. (But my browser can request only Japanese encoding charset.) thanks

product refresh and random number generation.
by Romain Slootmaekers 28 Jan '03

28 Jan '03

hi, I'm having problems with random number generation and product refreshes. To illustrate the problem, consider the following product code: class RandomNumberGenerator(SimpleItem.SimpleItem): """ ... """ def __init__(self,id): "initialize an instance" self.id = id self.__random = Random(time.time()) def next(self): """ returns next random number. """ return self.__random.random() ok, this works but whenever the product is refreshed or the zope server restarts, the generator will start to generate the same sequence of numbers, which is not what I want. I'm having trouble understanding what is happening: since the object gets pumped up every request it would make sense that you get the same random number if you lose some state from the internal random generator. But this isn't happening. You apparantly only lose state when the product is refreshed or when the zope server restarts. Could this be a cache effect ? (I could, as a last resort seed the generator with the current time every request, but then, I lose all guarantees about the period for the random number generation) any input appreciated. Romain.

How about some details about SGI's Supportfolio?
by Jean Jordaan 28 Jan '03

28 Jan '03

A couple of Zope Announce's ago, our attention was drawn to this press release: http://www.zope.com/News/PressReleases/SGI-2003-01-22 I was wondering if there are any stories behind that --- what technologies were used, what problems there were, how many people were involved in building it, what SGI's degree of participation was in the design, whether SGI now has inhouse Zope expertise with the ability to extend Supportfolio .. any interesting bits that the community can learn from. Actually, I'm not interested in Supportfolio exclusively --- I'd appreciate any stories about significant Zope implementations, if anyone has time to tell them, and is not bound by confidentiality issues. -- Jean Jordaan http://www.upfrontsystems.co.za

interaction with local FS
by Mario Bianchi 27 Jan '03

27 Jan '03

Hi everyone, I'm curious in finding out how zope interacts with the server's file system: let's say I want to allow the users of my site to manage (read/write) their own files on the server's file system, does Zope support this goal anyhow? As far as I've seen, to me the response seems to be no, it doesn't! The only way to access the server's file system from zope seems to be using the ExternalFile product, which is far from satisfactory from the point of view of file access rights: it only allows access to files owned by zope itself (or in the same group of zope's). No way to access 'someuser''s files with the uid of 'someuser'? Thanks, Mario. _________________________________________________________________ The new MSN 8: advanced junk mail protection and 2 months FREE* http://join.msn.com/?page=features/junkmail

RE: [Zope] interaction with local FS

There is a product called LocalFS, which will allow you access to the file system. However, the access is with the username/password specified in the properties of LocalFS, so it may be laborious to set up a LocalFS instance for each user you have.

Zope reference counts
by Ivo van der Wijk 24 Jan '03

24 Jan '03

Hi, I'm currently optimizing/analyzing a Zope server and I noticed the following: The number of references to specific objects (in this case specifically Squishdot comments) increases almost linear with the number of threads. Does this mean each thread keeps it's own cache pool of objects? Do these references point to the same object instances, or are these copied as well? I have the impression the memoryconsumption grows with the number of threads - is this true? Cheers Ivo -- Drs.

Registering Product with Control Panel
by Brian R Brinegar 23 Jan '03

23 Jan '03

Okay, I've got a product (Basic content object) Called HTMLBlock. When I start my ZEO Client with the product installed I don't recieve any error messages. The product is listed in the "Select type to add..." menu. However if I try to add an instance of the Product I recieve an AttributeError on HTMLBlock. After a little poking around I realized that the product is not listed in the /Control_Panel/Products/ list. The traceback I get when trying to add an instance is below. Thanks, -Brian Traceback (innermost last): File /data/www/Zope.mysql.pes161.HB10/src/Zope-2.5.1-src/lib/python/ZPublisher/Publish.py, line 89, in publish File /data/www/Zope.mysql.pes161.HB10/src/Zope-2.5.1-src/lib/python/ZPublisher/BaseRequest.py, line 278, in traverse File /data/www/Zope.mysql.pes161.HB10/src/Zope-2.5.1-src/lib/python/App/FactoryDispatcher.py, line 30, in __bobo_traverse__ File /data/www/Zope.mysql.pes161.HB10/src/Zope-2.5.1-src/lib/python/App/Product.py, line 66, in _product (Object: Products) AttributeError: HTMLBlock
