Finally I discovered that by removing the first %d on line 225 and self.addr[1] on line 226, while leaving everything else alone, it works fine. One curious thing though: When I run it this way, the line it writes in the log file begins with ^D. Where is that character coming from? Jim

Actually we aren't. ctsybasemodule was pretty ripe with problems and bugs, so we wrote our own which is still in the hands of the testers who helped pay for its development. It will be releases as soon as they give it the OK. Which should be very soon. Mind you, our 'module' is not a Python DB API complient module, but rather a thin wrapper around the sybase ctlib C library. A DB API module could be quicky and easily written with our C module, but we have not written one and we don't plan on it. The only thing we are providing is the new C module and a Zope Sybase databse adapter. -Michel

RE: [Zope-dev] Max objects before ZCatalog?

Between the > individual lookup, > doing a 'large catalog' ZCatalog search, and creating many ZCatalogs. 'large' here is a big number. ZCatalog stores it's index information in BTrees. Without getting into too much theory or insulting anyones intelligence, a BTree is a tree like data structure. When doing a 'search' you start at the top and work your way down the tree, comparing your search value to the value of each node in the tree. If you had on the order of a million objects, you would only make on the order of 10-20 or so comparisons. This is very fast and scales quite well. > > I'm accessing a few variable (~ 2-8) in 20-5000 (~max) subobjects and > testing them against the current objects variables.

But if you have 5000 cataloged objects, max, then you're well below flexing catalog. -Michel

ctsybasemodule
by Brusowankin, David 19 Nov '99

19 Nov '99

Hi, I noticed that you guys are maintaining ctsybasemodule for now. What is the latest version of ctsybasemodule ? Can I get it ? And, although I am not guaranteeing anything for NOW, I may be able to find some time to help in its maintainence. Please send me the bug list as well.

Writing custom folderish products
by Martijn Faassen 19 Nov '99

19 Nov '99

Hi there, I'm writing a product (in Python, not with ZClasses) which consists of: form - a folderish object to which you can add.. fields - a number of SimpleItemish objects that can be added to a form What I have working: * I can make the form behave like a folder by deriving it from OFS.ObjectManager * I have a number of fields that can be added anywhere in the Zope tree What I want to reach is this situation: * I want the form to behave like an folder, but only fields should be addable. and * Fields should not be addable anywhere but in a form. What set of incantations would accomplish this? Any example source? Or Zope source code I should study? Anything? Any hint in the right direction would be appreciated. Regards, Martijn

Replacing/Augmenting dtml-sqltest from a Product?
by Bradley McLean 19 Nov '99

19 Nov '99

Please forgive the somewhat naive question. I'm a seasoned C/C++, Java, Perl programmer new to Python and Zope. Hopefully someone can save me a little time. I've modified Shared/DC/ZRDB/sqltest.py and sqlgroup.py to provide some additional semantics that I find very useful. Specifically, I've added range and keyword operations, and comparisons other than equality to sqltest, and I've made a parameterized version of sqlgroup that allows selection of 'and' or 'or' linkages from a variable, making it easier to provide sophisticated search options on a Zope page. I'd like to make these modifications available for public review and comment. The best way I can think of to do this is to make a new Product that provides the new versions and replaces them in DC/ZRDB/DA/SQL. Can anyone give me a brief shortcut on how to do that? I can figure out how to make a Product, but figuring out how to either replace these classes, or to create a duplicate of SQL Method which uses them is not entirely obvious. TIA, -Brad

Max objects before ZCatalog?
by David Kankiewicz 19 Nov '99

19 Nov '99

What is the magic number for performance? Between the individual lookup, doing a 'large catalog' ZCatalog search, and creating many ZCatalogs. I'm accessing a few variable (~ 2-8) in 20-5000 (~max) subobjects and testing them against the current objects variables. The design is for something that most scale and can easily to be changed (I have this half done). The idea is really close to ZTopics, with my own idea of a minimalistic custom implementation. Is there anyone who has experience or has done performance testing and would like to comment? Thanks in advanced, David

RE-POST: getting Zap to work with cgi-bin directory?
by Michael Olivier 19 Nov '99

19 Nov '99

I'm reposting because I got no responses to this, and we're stuck. I would greatly appreciate any light you can shed on whether Zap should work with its cgi-bin like standard apache does, and how to troubleshoot problems. Ours isn't working and it isn't clear to us what else to try. --Michael Michael Olivier wrote: > > Hi folks, > > We've got Zope and Zap running but are having trouble with Zap's cgi-bin > directory.

mozilla and zope, update.
by Anthony Baxter 19 Nov '99

19 Nov '99

For those who are interested, Mozilla is very very close to being usable for working in Zope. At the moment, the killer is the open bug 6144 - Moz loses track of the auth header, and doesn't re-send it in. This means that in the management interface, you're not authorised, and so manage_workspace defaults to index_html, rather than manage_main. It's currently listed to be fixed before the next milestone release, M12, which is scheduled for 15th December. I'll post an update when it's fixed. Anthony

killing zombies
by Robin Becker 19 Nov '99

19 Nov '99

After putting the site I've developed on a live test basis I notice that I'm getting some zombie connections. I'm using the medusa active channel display code as in the code below. I notice that there are kill_zombies method for zhhtp_channel, but how should I use that method? My approach uses a similar approach, but is probably wrong. The zombie killers aren't happening in Zope as it stands. Can I ask why not? can I get the same thing to happen for other channels eg ftp etc? #status.py from ZServer.medusa.status_handler import channel_list_producer from ZServer.medusa.asyncore import socket_map from ZServer.HTTPServer import zhttp_channel from string import replace from time import time def __build(s): r='' while 1: t = s.more() if t=='': break r = r + t return r def get_active_channels(): r='' s=channel_list_producer('aaaa') r = r + replace(__build(s),'<p><a href="aaaa">Status Report</a>','') return r def kill_zombies(self): now = int (time()) for channel in socket_map.keys(): if channel.__class__ == zhttp_channel: if (now - channel.creation_time) > channel.zombie_timeout: channel.close() -- Robin Becker
