Mac os x, zope 2.11.0 importing products
by Giampiero Benvenuti 21 Jun '08

21 Jun '08

Dear all, I just installed successfully zope2.11.0 on my mac. I'm having a problem with importing some products. For instance ZMySQLDA (v. 2.0.8) gives me this error: ------ 2008-06-21T12:37:30 ERROR Application Couldn't install ZMySQLDA Traceback (most recent call last): File "/Applications/zope211/lib/python/OFS/Application.py", line 758, in install_product global_dict, global_dict, silly) File "/Applications/zope211/instance1/Products/ZMySQLDA/ __init__.py", line 91, in ? import DA File "/Applications/zope211/instance1/Products/ZMySQLDA/DA.py", line 155, in ? misc_={'conn': ImageFile( File "/usr/local/lib/python2.4/site-packages/PIL/ImageFile.py", line 74, in __init__ self.fp = open(fp, "rb") IOError: [Errno 2] No such file or directory: 'Shared/DC/ZRDB/www/ DBAdapterFolder_icon.gif' ------ After a google search I found this: http://dev.x3ng.com.br/browser/ Recria/buildout/patches/zmysqlda-imagefile.patch?rev=2386&format=txt It looks like the problem is related to PIL and after applying the patch (-from ImageFile import ImageFile +from Globals import ImageFile) everything works just fine. The question is: why this problem doesn't happen with zope2.10.5? I have the same setup... same python, same PIL. Applying the patch to the products doesn't look like a good school. Do you have any suggestion? Your help is much appreciated, Giampiero

record count in catalog
by Darryl Caldwell 21 Jun '08

21 Jun '08

Hi all, The Catalog tab in my catalog says this: The catalog "mycatalog" contains 30,345 record(s) in the path "/". But when I sort and return a list of cataloged objects I only have 19,881. Here is the script call to retrieve the records: context.mycatalog.search( {}, sort_index='lastname' ) Why don't the numbers match up? -d

template / context question
by Erik Myllymaki 20 Jun '08

20 Jun '08

I am trying to separate out small bits of HTML that are used on many pages of a site. In one case I use a secondary navigation on some pages in the right column that is supposed to look in the containing folder's sub-folders and list the Page Templates that is finds there. I create a folder called /templates/widgets and within there I have a Page Template called template-lister. <h2>Quick Links</h2> <ul tal:define="ztu modules/ZTUtils; raw python:context.objectValues('Folder'); location_folder_list python:ztu.LazyFilter(raw, skip='View')"> <li tal:repeat="location_folder location_folder_list"> <a href="" tal:attributes="href location_folder/absolute_url" tal:content="location_folder/title">Location Title</a> title <ul tal:define="raw python:office_folder.objectValues('Page Template'); posting_list python:ztu.LazyFilter(raw, skip='View')"> <li tal:repeat="posting posting_list" tal:condition="posting_list"> <a href="" tal:attributes="href posting/absolute_url" tal:content="posting/title">Posting Title</a> </li> <li tal:condition="not: posting_list"> No Postings at this time </li> </ul> </li> </ul> If I put this code directly in each Page Template that uses it, it works fine, but when removed from each Page Template and called like so: it uses the context of the "/templates/widgets" folder and does not work. Because this bit of TAL is used on many pages and the style of it changes often, I really want to pull it out into one place for easy updating. I know I am missing something elemental here ... Thanks for any advice.

ZODB and Zope Database Adapters
by Marco Bizzarri 19 Jun '08

19 Jun '08

Hi all. In the doc/ZODB3.txt of Zope 2.8 (and Zope 2.9) I've found the following paragraph. " ZODB 3 and Zope Database Adapters Most database adapters are *currently* likely to be problematic unless the underlying extensions and libraries: - allow multiple simultaneous database connections, - are thread safe, - give up the Python global interpreter lock when making database calls. This is only a problem when running Zope 2 with multiple threads. " I would like to know if anyone has experience of some of these problems with psycopg 1.1 and ZPsycopgDA Regards Marco -- Marco Bizzarri http://iliveinpisa.blogspot.com/

Apart from a few minor bug fixes, it provides a few new features: Some highlights: * mxTools now has a new mx.Tools.dlopen() function which allow loading shared libraries explicitly and from a specific path. This allows working around problems with not being able to dynamically set LD_LIBRARY_PATH on Unix platforms. * mxTools can be configured to expose a new API called mx.Tools.setproctitle() which allows setting the process title on Unix platforms. * mxBeeBase comes with a new on-disk dictionary version called BeeFixedLengthStringDict, which allows using keys with embedded \0 characters. * mxSetup, our Python distutils extension, can now build prebuilt archives that no longer require the "... build --skip ..." command to skip the build process. The uninstall command now also works for prebuilt archives and the bdist_prebuilt command has been enhanced to be able to build pure Python distributions as well. * mxSetup now also works together with setuptools to e.g. build and install the packages as eggs. Run setup.py with --use-setuptools to enable this support. For a more detailed description of changes, please see the respective package documentation on our web-site. As always, we are providing pre-compiled versions of the package for the most popular Python platforms.
