All Of My Zope 2.6 Transactions Since 2/6/07 Are Gone!
by Mark, Jonathan (Integic) 03 Apr '07

03 Apr '07

Zope 2.6.2 on Red Hat 7.3 started acting flaky a week or two ago. It started dying every day or so. Then it lost all transactions since 2/6/07, displaying content as it was two months ago. Then it recovered the lost content, now it has lost it again. Zope Undo shows incorrectly that there were no transactions between 2/6/07 and 3/28/07 when the data loss occurred. What is the best approach to getting this data back?

about LocalFS
by Alan 02 Apr '07

02 Apr '07

Dears, Just checking and maybe looking for some advices. My application in Zope depends on LocalFS. I want to make my application reproducible at other Zope servers. My question is if LocalFS is still maintained and under developed and if so is there any other version newer than http://www.easyleading.org/Downloads/LocalFS-1.7rc1-andreas.tar.gz/view? In order to still use LocalFS I need to hack in its code and it's not such a thing I would like to request to another user to do if he/she wants to do my application. If I have to move from LocalFS, which other product would replace it keeping at least LocalFS features? Many thanks in advance. Regards, Alan

ZSQL, call for early beta testers
by Peter Bengtsson 02 Apr '07

02 Apr '07

I've developed a little module that makes it really easy to plug in .sql files into a python product class as ZSQLMethods. It's extremely easy to use and doesn't require any CMF or ZODB stuff. It also has support for memcache for those of you with slow db queries that you need to repeat. It works something like this:: from Products.ZSQL import initializeSQLfiles class _SQLBase(Acquisition.Implicit): dbConnection = 'Psycopg_database_connection' class SQLUser(_SQLBase): pass folders2classes = {'sql/Userstuff': SQLUser} home = package_home(globals()) initializeSQLfiles(folders2classes, home) If in the folder 'sql/Userstuff' you have a file called 'select_users.sql' you will the be able to just run: # select users: print SQLUser.select_users() # same but first printed the final SQL used print SQLUser.select_users(debug__=True) # save time for the next call print SQLUser.select_users(memcache__=True) Is anybody interested in a being early beta testers before I release it as Open Source? It works quite well here for me but I fear I'm getitng a bit home blind based on just my needs. I'm pretty sure it works but some early feedback would be appreciated.

include?
by Katie 02 Apr '07

02 Apr '07

We're almost finished getting the new site done completely in zope using css and mySql. We have an older portion of the old site done in php thought that we don't really want to re-write. We'd like to include it in the dtml document page that has all the common elements of every page but I'm at a loss of a way to do it other than using an inline frame. Is there a dtml include that takes a url string the way the <dtml-var> tag renders the associated file? Katie

z3c.rml 0.5 released!
by Stephan Richter 02 Apr '07

02 Apr '07

Hi everyone, I am very proud to announce the release of z3c.rml version 0.5, an independent implementation of the ReportLab Markup Language (RML). RML is a XML dialect that describes the generation of a PDF using the ReportLab PDF generation library. This release focuses on compatibility with the RML version developed by ReportLab, Inc. In the future, however, the plan is to divert from the original API to fix inconsistencies between the RML Specification and the ReportLab API and to extend beyond the original functionality. Features -------- - Full support of all common RML directives. - Support for merging in pages from external PDF files thanks to pyPdf. - Directives are fully documented using an extension to Zope's interfaces and schemas. - Code-generated DTD file. - Code-generated RML Reference document, of course as PDF built with z3c.rml. - Optional integration of page templates, allowing dynamic RML documents to be created. - Support for charts. - Test suite with 90 files. Roadmap to 1.0 -------------- - Fix inconsistencies between ReportLab and RML APIs. - Finish the documentation of the chart support. - Finish the page insert and merge functionality. - Improve the DTD generator and possibly write a generator for RelaxNG. - Integration of a hyphenation support, if a proper package can be found. Installation ------------ z3c.rml has been uploaded to the Python cheese shop. Thus you should only need to say: easy_install z3c.rml Unfortunately, easy install will not install the ``reportlab`` dependency, since it is not available in the cheese shop. This will have to be done by hand. Also, by default the pagetemplate support is not enabled, because of the many dependencies. However, if you want the pagetemplate support, you can simply install it or install the "zope.pagetemplate" egg. Questions and Comments ---------------------- If you have any questions or comments, please feel free to contact the Zope 3 Users mailing list at zope3-users(a)zope.org or E-mail me directly at srichter(a)cosmos.phy.tufts.edu.
