Scaling problems, or something else?
by Gaute Amundsen 22 May '07

22 May '07

Just a quick call for ideas on this problem we have... Setup: Zope 2.7.5 (~180 sites) -> apache (-> varnish for 1 high profile site) Most noticeable symtoms: Takes 30 sec. or more to serve a page, or times out. Sporadic problem, but allways during general high load. Lasts less than 1 hour. Restarting zope does not help. Lots of apache processes in '..reading..' state Apache accesses and volume is down. Server load is unchanged, and < 2.0 Apache processes is way up (~250 aganinst <40) Netstat "established" connections is WAY up (~650 aganist < 50) Is this zope hitting some sort of limit and just letting Apache hang? Would setting up ZEO on the same box make a difference, or would it be better to extend varnish coverage? What would you do to pinpoint the problem? Any ideas are welcome! Regards Gaute Amundsen

MailingLogger 3.1.0 Released!
by Chris Withers 17 May '07

17 May '07

Hot on the heals of the 3.0.0 release, this 3.1.0 release offers support for SMTP hosts that require authentication in order to send mail... Mailinglogger enables log entries to be emailed either as the entries are logged or as a summary at the end of the running process. This pair of enhanced emailing handlers for the python logging framework is now available as a standard python package and as an egg. The handlers have the following features: - customisable and dynamic subject lines for emails sent - emails sent with an X-Mailer header for easy filtering - flood protection to ensure the number of emails sent is not excessive - fully documented and tested In addition, extra support is provided for configuring the handlers when using ZConfig, Zope 2 or Zope 3. Installation is as easy as: easy_install mailinglogger For more information, please see: http://www.simplistix.co.uk/software/python/mailinglogger cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Conditional import of annotations for Zope 2.9 and 2.10: how?
by Maurits van Rees 17 May '07

17 May '07

Hi, In Zope 2.9 (or 3.2) the annotations module is in zope.app.annotations. In Zope 2.10 (or 3.3) it is in zope.annotations. In a product for zope 2.9 I used to do this in zcml: <include package="zope.app.annotation" /> and this in code: from zope.app.annotation.interfaces import IAnnotations from zope.app.annotation.interfaces import IAttributeAnnotatable This of course gives problems in zope 2.10/3.3. The code part is easily fixable to run in all versions: try: from zope.app.annotation.interfaces import IAnnotations from zope.app.annotation.interfaces import IAttributeAnnotatable except: # Zope 2.10+/3.3+ have a different location for annotations from zope.annotation.interfaces import IAnnotations from zope.annotation.interfaces import IAttributeAnnotatable But how should I fix up the zcml? With the zcml above, zope 2.10 does not start. With this: <include package="zope.annotation" /> zope 2.9 does not start. That is to be expected. zcml:condition to the rescue:  <include zcml:condition="installed zope.app.annotation" package="zope.app.annotation" />  <include zcml:condition="installed zope.annotation" package="zope.annotation" /> Zope 2.9 is fine with this. And the tests for my product that make use of annotations pass. But now zope 2.10 cannot start: zope.configuration.xmlconfig.ZopeXMLConfigurationError: File "/home/maurits/instances/plone3/etc/site.zcml", line 15.2-15.23 ZopeXMLConfigurationError: File "/home/maurits/instances/plone3/Products/eXtremeManagement/configure.zcml", line 7.2-7.31 ZopeXMLConfigurationError: File "/home/maurits/instances/plone3/Products/eXtremeManagement/actual/configure.zcml", line 6.2-7.43 IOError: [Errno 2] No such file or directory: '/opt/zope/zope2.10.3/lib/python/zope/app/annotation/configure.zcml' So I change the code so both zopes can start:  <include zcml:condition="have zope.app.annotation" package="zope.app.annotation" />  <include zcml:condition="have zope.annotation" package="zope.annotation" /> Now zope 2.10 looks fine. Its tests fail but that is due to other reasons. Within a zopectl debug session I can adapt to IAnnotations. But now the tests in 2.9 fail because adapting does not work: TypeError: ('Could not adapt', <Task at >, <InterfaceClass zope.app.annotation.interfaces.IAnnotations>) So: neither the conditions 'have' nor 'installed' work for both zopes. What other options are there to do this in zcml? Or should I take my loss and translate the zope/(app/)annotations/configure.zcml file (which only registers one adapter) into python code? -- Maurits van Rees | http://maurits.vanrees.org/ [NL] Work | http://zestsoftware.nl/ "Do not worry about your difficulties in computers, I can assure you mine are still greater."

Zope-konsulter i Sverige - People/companies working/consulting with Zope in Sweden
by Dario 17 May '07

17 May '07

Hello, [In english at the end]. Jag håller på med en liten kartläggning av hur svårt/lätt det är att få tag på Zope-kompetens/konsulter i Sverige. Jag behöver lite hårda fakta för att antingen verifiera eller motsäga ett visst mått av FUD som sprids. Jag vore tacksam om ni som säljer Zope-kompetens kunde höra av er till dario(a)chalmers.se med en kort beskrivning av vad ni kan erbjuda. Jag vill betona att detta enbart en kartläggning, vi planerar inte att köpa några konsulttjänster i en omedelbar framtid. ### I am doing some small research for my university and we need to get a realistic estimate of how easy/hard it is to get hold of Zope-compentence for hire in Sweden. There is some degree of FUD being spread, and I need to have some hard data to confirm or invalidate the FUD. If you or your company sell Zope-competence in Sweden, I would be gratefull if you could send me a message with a short description of your offering. My email address is dario(a)chalmers.se. I'd like to emphasize that this is only research to get an estimate of Zope-competence availability, we have no plans for a business engagment in the immediate future. ### Thank you/Tack på förhand, Dario Lopez-Kästen IT Systems & Services Chalmers University of Technology -- -- ------------------------------------------------------------------- Dario Lopez-Kästen, IT Systems & Services Chalmers University of Tech.

by Tres Seaver 15 May '07

15 May '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the CMF developer community, I am pleased to announce the release of version 1.6.4 of the Zope Content Managment Framework (CMF). This is a bugfix release, and is a recommended upgrade for users running an earlier release of the CMF in the 1.6.x line. What is the CMF? The Zope Content Management Framework provides a set of services and content objects useful for building highly dynamic, content-oriented portal sites. The CMF provides the foundation for popular software packages such as Plone. It is intended to be easily customizable, in terms of both the types of content used and the policies and services it provides. Where do I get it? For release files, change logs, installation instructions and more please visit "http://www.zope.org/Products/CMF/CMF-1.6.4", http://www.zope.org/Products/CMF/CMF-1.6.4. Roadmap and release information can be found at "http://www.zope.org/Products/CMF/docs/roadmap", http://www.zope.org/Products/CMF/docs/roadmap.

Re: MailTemplate multipart/alternative samples

Glad they worked well so far :-) > May I have some hints/sample how to use MailTemplates for > obtain a multipart/alternative message? > > For example the first part plain/text e and the second one > text/html and no file attachment. Sure, what I'd do is use the template to generate the html and render that to a message: msg = container.my_html_mail.as_message( mfrom='from(a)example.com', mto='to1(a)example.com', subject='Your requested file', ) Then I'd add a Mimetext object with the plain text version: from email.mime.text import MIMEText msg.attach(MIMEText(text_version_of_your_message)) And finally send the message: msg.send() Of course, the "fun" bit is generating the plain text version of the message from the html version. You might try stripogram for that: http://sourceforge.net/project/showfiles.php?group_id=1083&package_id=34645 ...but your milleage may vary (a lot!) cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

tp whom it may concern

I just wanted to pay my respect to the makers of Zope and Zope 3 in particular. I've spent nearly 2 months (I'm not that smart - things take their time) with it now, and I'm far from tired of it. I will perhaps use grok at some point - but I'd like to be able to switch on the computer, before I start playing with it ;-) med venlig hilsen / with kind regards Jørgen G.
