I am trying to make the following with XMLDocument: Extract a branch of the xml-tree and adding a xml header with apropriate xsl which the browser which can recogniz xml can use the xsl to render the branch of the tree. I have made a method which have : <?xml version="1.0"?> <dtml-var "toXML()"> however, Zope send <html><head> <base href="http://..... before the method's output. Can I ask Zope not to send this?

I import the Application module, and modify the class. Not recommended for objects, only for new class methods.

Performance
by Chad Dyer 12 Feb '00

12 Feb '00

We are considering using ZOPE to manage our consumer web sites. In aggregate they currently do 500,000 page views a day. We need them to scale to 2 million page views. Their not Yahoo! but it is enough of a load that I am concerned about the performance ZOPE can provide. The feature set of ZOPE looks great and but I need to work through the performance issues. I've spent quite a bit of time looking at example ZOPE sites and none appear to be huge trafficed sites. They seem to be more vertical developer sites or business-business sites that have lots of features but not necessarily tons of users banging on them at once. Does anyone have benchmarks or performance information from either a software or hardware standpoint they can send me? Chad Dyer

Servlets - Zope
by Dave 12 Feb '00

12 Feb '00

I'm a Zope newbie. For the past 2 years I've been writing web apps using Java Servlets that use databases heavily. With Servlets I've used Connection pools to speed up access. Could someone give me a rough idea of how Zope (say using MySql) handles heavy database integration (i.e. Does Zope create a connection pool, Is there a limit on the number of connection within Zope, etc...) ? Could you (would you need to) create a pool to cache Db connections? Also, on a side note. Has anyone looked at the need or possiblity of hooking Zope to Apache JServ to run Servlets from Zope? Thanks, Dave Bryson

Mail access via ZOPE (IMP?)
by Jonas Juselius 12 Feb '00

12 Feb '00

Hello, Is anybody working on IMAP mail support for Zope? I just had look at WorldPilot (http://www.worldpilot.com) and found it inflexible and impossible to integrate (at least without rewriting a substantial part of the code) with the rest of my site. It is basically just one big object which cannot be configured in any way. Also, it includes lots of stuff like calendars, ToDos, and more which IMHO belong in the Portal toolkit. What I'm looking for (or requesting, since I simply don't have the time to write it myself ;), is something like IMP for php, but for Zope. An IMAP product written in a modular way so that it's look and feel can be customized, a bit like the Portal toolkit. I have users who travel a lot, and it would be really nice for them to be able to access their mail via the web while aborad... Best regards, jonas -- And what is good, Phaedrus, And what is not--- Need we ask anyone to tell us these things? [ PGP public key: finger jonas(a)radon.pc.helsinki.fi ]

Zope (or Python?) not completely thread-safe...?!
by news-list.zope.dev＠innominate.de 11 Feb '00

11 Feb '00

hi! i spent several hours looking for a bug which caused my whole zope system to be hanging. the solution was this: i've been using <dtml-sendmail> to send out emails but due to a network change my smtp-host had changed and i was trying to use a server that wasn't answering to my smtp-request due to some firewall-something. ok, one zope thread was waiting for a reply from the smtp-server but as a consequence all other zope threads were blocked in some way so that i couldn't access my zope system anymore. is that a normal behaviour...?! OS is linux-2.2 ... i would have expected one thread to be waiting and the others to be serving requests as usual... thilo -- mezger(a)innominate.de innominate AG networking people fon: +49.30.308806-11 fax: -77 web: http://innominate.de pgp: /pgp/tm

Zope Product Reload
by Andrew Lahser 11 Feb '00

11 Feb '00

I understand its possible to reload a module with python. Theoretically, it should be possible to reload a Zope Product without restarting Zope. I would like to develop a Product/Patch/External Method that would allow this. After a couple hours of research, I have more questions than answers. If anyone has looked at this, I would appreciate some insight. Here are a few questions. 1. It appears that Zope puts in its own __import__ and reload hooks, is this correct? Why does Zope do this? 2. Just setting up a simple method, such as the following doesn't work either. import Products from CStringIO import StringIO def manage_reload(self, product_name, REQUEST=None): """Reload a Product without restarting Zope""" if hasattr(Products, product_name): product=getattr(Products,product_name) else: return 'Product not found' modules=sys.modules try: reload(product) except: f=StringIO() traceback.print_exc(100,f) f=f.getvalue() try: modules[pname].__import_error__=f except: pass The strange thing about this method is that the module DOES get reloaded, but the new module doesn't appear to get used. Very puzzling! Mostly, I am wondering if anyone else has tried or thought about this problem. Developing products can take many, many iterations, and I am just tired of waiting the three or four seconds for Zope to restart. Drew
