Choice of HTML editors
by Ian Nunn 21 Jan '05

21 Jan '05

I'd be interested in what experienced Zope developers use. HTML I've seen output from FrontPage is rather verbose and complex. I personally use the freeware version of AceHTML and largely write my own simple HTML with it. I assume the development process is create the basic page layout in an editor and then insert Zope tags. What are the "best practices" people use in this regard? Best Regards Ian Nunn School of Computer Science Carleton University, Ottawa, ON, CA

New ZMysql adapter connection problem
by Larry McDonnell 18 Jan '05

18 Jan '05

Hi, I'm test 2.7.3 out and I cannot create a connection to my database. I am using the new adapter ZMySQLDA-2.0.9b2 <http://sourceforge.net/projects/mysql-python/> .and I loaded MySQL-python.exe-0.9.2.win32-py2.3.exe pointing it to the bin directory of my zope installation. It added it to my product list but when I try to make a connection I see the following: Traceback (innermost last): * Module ZPublisher.Publish, line 175, in publish_module_standard * Module ZPublisher.Publish, line 132, in publish * Module Zope.App.startup, line 204, in zpublisher_exception_hook * Module ZPublisher.Publish, line 101, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module Products.ZMySQLDA.DA, line 106, in manage_addZMySQLConnection * Module Shared.DC.ZRDB.Connection, line 64, in __init__ * Module Shared.DC.ZRDB.Connection, line 97, in edit * Module Products.ZMySQLDA.DA, line 126, in connect * Module Products.ZMySQLDA.db, line 183, in __init__ AttributeError: server_capabilities (Also, an error occurred while attempting to render the standard error message.) I also tried a password option but still no connection. I know I could do the above in 2.6.1. Thanks, Larry

[Security advisory] Zope 2.7 + 2.8
by Andreas Jung 12 Jan '05

12 Jan '05

Synopsis: Due to an error in the cAccessControl module of Zope it is possible to bring down a complete Zope site as documented in http://mail.zope.org/pipermail/zope-dev/2004-December/024087.html This exploit causes a segmentation fault of the Python interpreter. Vulnerable for this exploit are at least all Zope installations that allow untrusted users to edit ZPTs (possibly DTML as well) either through the ZMI or through the file system. Affected versions: Zope 2.7.X, Zope 2.8.X Recommended solution: Turn off cAccessControl and enable the Python AccessControl implementation in etc/zope.conf (this line is commented in the default configuration): security-policy-implemenation python A fixed implementation of cAccessControl will be included in the upcoming Zope 2.7.4 beta 2 release. ---- Andreas Jung Zope 2 Release Manager

Re: [Zope] GPL question
by Alan Snyder 12 Jan '05

12 Jan '05

I guess I'm still unsure about what the phrase "based on" and "derived from" means in the context of writing content and building a site based on plone and zope. My stuff wouldn't be able to work directly without plone and zope, but on the other hand, it's not an extension of plone and is not derived from it either. I'll have to keep poking around.

Rotating ZEO logs?
by Paul Winkler 30 Dec '04

30 Dec '04

Hiya folks, I don't know why this never occurred to me before, but the ZEO server doesn't seem to have an equivalent to Zope's log rotation signal handling. From the Zope Book: """ The common idiom after rotating Zope log files is: kill -USR2 `cat $ZOPE_HOME/var/Z2.pid` """ What do people do with their ZEO server log? there's no pid file and it doesn't respond to SIGUSR2 AFAIK... -- Paul Winkler http://www.slinkp.com

Re: [Zope] What did your Zope server do in 2004?

I can only really take a wild guess since we only keep 20 days of zope logs. But if I extrapolate linearly from that, then reduce by 20% to account for some growth, I get the following totals for our two zope servers (they run different sites): host1 host2 total daily avg (total) pages 379176 516876 896052 2455 hits 11052010 2526993 13579003 37202 GB transferred 291 33 322 0.88 -PW

tal:repeat and first and last.
by Pupeno 30 Dec '04

30 Dec '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello Zopers I need to do something except on the first and last item of a tal:repeat. After some time of testing I've found that with the following code: which iterates 4 times I've got: True True True 1, and with I've got: 1 True True True. In any condition, 1 and True are the same, so, I couldn't build my condition. What am I doing wrong ? Should I get one true and three flases ?

How to create zope objects without using the ZMI?
by Michael Lee 30 Dec '04

30 Dec '04

Is there another way to create zope object? Is it possible to write a python script to create object, say a file or a page template? If the answer is yes, how? Thanks in advance.
