It's interesting to see z3c.rml knocking around. I've often questioned the legal existence of z3c.rml. As far as I remember, RML forms part of the commercial stuff that ReportLab (the company) offers and I'm not sure even the spec of the xml and/or the name RML are available for use without talking to ReportLab first... Anyway, just thought I'd mention it as legality is something people should take into account even in the open source world ;-) Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

I think you need to review the c.buildout documentation and try to setup a project. Probably take a look at zopeproject I think available on PyPi. I think it should be possible to write a script or use the existing scripts in z3c.rml and use the z3c.recipe.dev:script to generate a working starting point based on buildout for running your PDF conversion script. At least buildout makes sure that your packages are installed correct as working unit. Also a good starting point is the READEM.txt file in the z3c.rml package. There are several tests which will produce several PDF based on rml code. > If I cd into the 'tests' directory, and try this: > python text_rml.py > > I get almost the same traceback (just with 'text_rml.py' > replacing 'rml2pdf.py'). > > Am I trying to run this correctly?

When I debug things like this I use some combination of fstail and a hacked ZEO client that triggers a pdb each time an object is stored. Using one or both of those you should be able to track down what kinds of objects are being written. From there hopefully you'll be able to determine what is causing the writes. -- Benji York Senior Software Engineer Zope Corporation ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Attempting to use z3c.rml properly...
Hi All, I've given up on using z3c.rml (or indeed reportab's open-source software) with Google's AppEngine as the restrictions they were too constraining. Now, I just want to be able to run z3c.rml on my machine at home to verify how it works. Once it works, I'll be able to upload it to a regular web host with less restrictions. So, starting with a clean z3c.rml 0.8.1: Installing onto a XP Pro SP3 machine, Python 2.5 with setuptools. I did a 'python setup.py install' for zope.event, zope.interface, zope.schema, and zope.i18nmessageid first. Everything except zope.i18nmessageid went well. Then, I did the same for z3c.rml. It pulled in all the dependancies (downloaded lxml 2.2, and checked zope.schema 3.5.5, zope.interface 3.5.2, reportlab 2.3, pyPdf 1.12). Okay, now what? How best to launch this? If I cd into C:\Temp\z3c.rml\src\z3c\rml, and give this command line: python rml2pdf.py tests\input\simple-layout.rml I get this error: Traceback (most recent call last): File "rml2pdf.py", line 24, in from z3c.rml import document, interfaces File "c:\python25\lib\site-packages\z3c.rml-0.8.1dev-py2.5.egg\z3c\rml\document.py", line 26, in from z3c.rml import attr, directive, interfaces, occurence File "c:\python25\lib\site-packages\z3c.rml-0.8.1dev-py2.5.egg\z3c\rml\attr.py", line 35, in from z3c.rml import interfaces File "c:\python25\lib\site-packages\z3c.rml-0.8.1dev-py2.5.egg\z3c\rml\interfaces.py", line 138, in class IDeprecatedDirective(zope.interface.interfaces.IInterface): AttributeError: 'module' object has no attribute 'interfaces' If I cd into the 'tests' directory, and try this: python text_rml.py I get almost the same traceback (just with 'text_rml.py' replacing 'rml2pdf.py'). Am I trying to run this correctly? I'd put money on my doing something ham-fisted here, but I can't see what it is. Just for context, it'd be hard to underestimate my experience with Python. I've only been at this a week or so, and figuring out things as I go, so please don't worry about hurting my feeling by going too simple! Thanks for any help. -Ken ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] zodb is growing every login/logout
@Paul: yes, ZODB just grow after login and logout. @Nikolay: Yes, I'm using the default persistent zope3 session. This was also my first idea, and I switched to a RAM Session, but it had no effects. I tested the RAM Session by restart zope, and I where logged out after restart (so I think the RAM session is working by losing the login-data). But the ZODB was growing again. Here is my code to switch the session and my session class: - #from zope.session.session import RAMSessionDataContainer from zope.session.session import PersistentSessionDataContainer class MySession(PersistentSessionDataContainer): timeout=5*60*6 def __init__(self): super(MySession,self).__init__() # timeout session 5 minuten: self.timeout=MySession.timeout self.resolution=1*60 --- But i switched just in the app, maybe I have to change the global session in zope?
