z3c.offlinepack
by Ross Patterson 26 Sep '07

I wrote a small script for packing ZODB storages without running zope complete with buildout support for quick deployment without modifying the system. Attached is the README for more details. I hope this is useful for some. Also, I can't seem to get the ReStructuredText in the long_description on the pypi page to display as ReStructuredText instead of just displaying as test. Anyone got any pointers? http://cheeseshop.python.org/pypi/z3c.offlinepack Ross ================== Pack ZODBs Offline ================== Pack a ZODB storage without running any part of the Zope application server. Only an appropriate version of ZODB3 for the ZODB storage is required. Apply only to copies of ZODB storages, not ZODB storages currently in use. Install the distribution:: $ python setup.py install Then use the offlinepack script to pack a copy of your ZODB:: $ offlinepack /path/to/Data-copy.fs zc.buildout ----------- A buildout.cfg is included that will install the offlinepack script to the buildout. The buildout makes it possible to quickly use the offlinepack script without modifying the system python installation:: $ svn co svn://svn.zope.org/repos/main/z3c.offlinepack/trunk z3c.offlinepack $ cd z3c.offlinepack $ python bootsrtap/bootsrtap.py -v $ bin/buildout -v $ bin/offlinepack /path/to/Data-copy.fs The buildout.cfg file can also be modified to use a specific version of ZODB3. This is uesful if you need to use offlinepack without migrating the ZODB to a newer version of ZODB3. Add the version specifier to the offlinepack section of buildout.cfg. For example, to use offlinepack with Zope 2.9, use the following offlinepack section. [offlinepack] recipe = zc.recipe.egg:scripts eggs = z3c.offlinepack ZODB3<3.7-dev

Hi! Every night my Zope server has 99% cpu usage and, sometimes, the server stops to serve pages There are any way to know what the Zope server is doing in real time? I know I could look at event.log or z2.log but I would like to know the activity in real time Is this posible? How can I know what my server is doing? Thanks! -- Mis Cosas http://blogs.sistes.net/Garito

help with customizing error messages, Zope 2.9
by Dennis Allison 21 Sep '07

21 Sep '07

Zope 2.9.X, python 2.4 I am in the process of making error messages suitable for a non-techie audience. I want the "real" messages to go into the event log and a undetailed custom message to be displayed. We'll probably want to be able to choose whether or not to display the non-techie messages since we do our development through the web. I have been reading the code and am a bit confused. standard_error_message is a DTML method at the root which is supposed to provide hooks for the application to specify it's own error messages. standard_error_message should be acquired. It should be possible for there to be multiple copies with the particular one to be used selected by acquisition. This does not appear to be the case for some errors in my configuration, but I am not sure why. There appears to be nothing in the Zope 2.9 zope.conf file that has to do with catching error messages. Is there some configuration that is missing to enable full custom error messages. Looking at the code: ZPublisher/HTTPResponse.py seems to have a complete set of error responses hard-wired with outputs that mimic those of the default standard_error_message. OFS/SimpleItem.py includes a method called raise_standardErrorMessage which first acquires and then publishes the standard_error_message. Zope2/App/startup.py has a method, zpublisher_exception_hook which uses raise_standardErrorMessage and is referenced in ZPublisher/Publish.py where it is used to set error_hook, but error_hook does not appear to be used. It would be helpful to me if someone who understands how this particular code works could provide some hints as to what's needed to fully customize the error message responses.

Two ZEO instances running on same server?
by michael nt milne 18 Sep '07

18 Sep '07

I've got one ZEO instance of Plone 2.5.0 and one ZEO instance of Plone 2.5.3running on one UNIX server. These were both installed using the unified installer for UNIX. I've modified the ZEO ports and also all the ZOPE ports so that there a no conflicts between the two instances. When I access the ZMI in both instances I am seeing Plone sites mirrored between the two instances. Even though the data.fs file for both sit in different areas ....opt/Plone-2.5/zeocluster/.... opt/Plone-2.5.3/zeocluster. What I get is site names etc displayed which haven't been created in that instance and vice versa. When clicking on the site, no actual data is displayed and also skins aren't correct. It also looks like the /Products directories are mirrored in ZOPE. However if I go into site set-up in Plone and add/remove products the correct products are listed for each instance. -- michael

how to get next iteration values?
by Jaroslav Lukesh 17 Sep '07

17 Sep '07

Hi, does somebody knows how to get next iterations of columns from SQL query? I think that is only due my unknowledge of right pythonic syntax. <dtml-let vypisSQL_LET="vypisSQL()"> -- ZSQL method results catch <dtml-in vypisSQL_LET prefix="listing"> current value: <dtml-var column> next value: <dtml-var "vypisSQL_LET.column[listing_number]"> -- here is an error </dtml-in> </dtml-let> Do you have some ideas how to get next value, please? It is possible to do with fill ['','',''....] fields or with memorizing/display last values as a main result, but it is not what I want, it is quite large sequence and ### columns. Many thanks, JL.

utf-8 over xmlrpc with zope2.9
by Kevin 13 Sep '07

13 Sep '07

I am trying to send unicode encoded utf-8 or latin1 strings over xmlrpc to a method in zope. The method in zope tries to decode the string and it seems detects ascii. I then recieve an error that "UnicodeDecodeError: 'ascii' codec can't decode byte 0xf3 in position 4: ordinal not in range(128)" I can re-create this error in a python shell by doing something like: >>> s = 'helló' >>> s2 = unicode(s,'ascii') so after looking at code, I assume this is what is happening instead of >>> s2 = unicode(s,'iso-8859-1') If I submit to this method from an html form, I have no error and the data is stored perfectly. I have tried setting the encoding of xmlrpclib.Server to utf-8 and latin1(iso-8859-1) and making a custom transport for xmlrpclib where I add charset='utf-8' or charset='iso-8859-1'. Is is not possible to send unicode characters > 128 to zope? The method is LDAPUserFolder.manage_edit_user()
