Unexpected behavior with zope.session 3.9.5

Hi List,

I'm running into an bit of a problem implementing zope.session on Zope2-2.12.10.
When running the following code inside a class that inherits from BrowserView:

session = ISession(self.request)[product_id]

I get the following error.

AttributeError: ZServerHTTPResponse instance has no attribute 'getCookie'

Looking through the zope.session code, the Session object adapts IRequest.   The exception is being thrown
in zope.session.http.CookieClientIdManager in the the getRequestId() method with the following code.

def getRequestId(self, request):
	'''....'''
	response_cookie = request.response.getCookie(self.namespace)

I am not sure where to begin tracking this down.   Could this be an error with utility lookup?

Yes, unfortunately.

I can see it, but I've 2.12.XX and this should be fixed. This is the 
code in http.py:

     def getPreferredCharsets(self):
         '''See interface IUserPreferredCharsets'''
         charsets = []
         sawstar = sawiso88591 = 0
         header_present = bool(self.request.get('HTTP_ACCEPT_CHARSET'))
         for charset in self.request.get('HTTP_ACCEPT_CHARSET', 
'').split(','):
             charset = charset.strip().lower()

isn't HTTP_ stripped from the request variable name?

can you send me your workaround? Maybe it can help :P

UnicodeDecodeError

Hi!

  I've an Zope application, basically postgres + zpt.

  The postgres db has been upgraded to 8.5, the data inside is utf-8 
(dumped and checkd it), the pg adapeter is the latest, and the "*Z 
Psycopg 2 Database Connection" is configured to use utf-8.* Zope is  
2.12.20 + latest security fix.

  When I try to do:

<span tal:replace="result/?column" /> (result came from an ZSQL method) 
I get an UnicodeDecodeError:

Traceback (innermost last):
   Module ZPublisher.Publish, line 127, in publish

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 38: 
ordinal not in range(128)

if I do:

<span tal:replace="python:str(result['column']).decode('utf-8')" /> it 
works. (I use str because I've also dates in the record, otherwise I 
could not decode being it not a string)

I've several zpt to fix, and I would like it to work as it should. My 
analisys is that result['column'] is seen as a plain string with \xx 
characters inside, and decode just transform it in something that Zope 
recognize as utf-8 when it prints it.

Anyway, any idea?

Re: Finding the right import folder

Write a browser view or use an external method.
It's well known that Python scripts are  restricted.

Finding the right import folder

I have a Zope instance running on a FreeBSD (8) server.  Zope is running fine
(by all measures).  Here is the particulars of the system:

Zope Version
   (Zope 2.7.9-final, python 2.4.5, freebsd8)

Python Version
   2.4.5 (#2, Nov 10 2011, 00:37:52) [GCC 4.2.1 20070719 [FreeBSD]]

System Platform	
   freebsd8

SOFTWARE_HOME
	/usr/local/www/Zope/lib/python

ZOPE_HOME
	/usr/local/www/Zope

INSTANCE_HOME
	/usr/local/setp

CLIENT_HOME
	/usr/local/setp/var

Network Services
	
ZServer.HTTPServer.zhttp_server (Port: 8080)
ZServer.FTPServer.FTPServer (Port: 8021)

-------------------------------

The problem is that I need to import some .zexp files.  I would have thought
that I should put them in the (already existing) import folder at the
INSTANCE_HOME (i.e., /usr/local/setp/import) but when I restart Zope, none of
the .zexp files (including the standard Zope tutorial) show up in a pull-down
menu in the import page.  Based on the above, where should I put the .zexp files
so that the Zope instance finds them.

changing permissions on classes/methods at runtime?

hi all!

is it possible to change permissions and roles on classes/methods
at runtime? normally you'd attach security declarations inline in
your class definition code:

from AccessControl import ClassSecurityInfo
from AccessControl.class_init import InitializeClass
class Cls():
   security = ClassSecurityInfo()
   security.declarePrivate('foo')
   def foo(self):
     pass
InitializeClass(Cls)

now what i tried at runtime is:

from mycode import Cls
from AccessControl import ClassSecurityInfo
security = ClassSecurityInfo()
security.declarePublic('foo')
security.apply(Cls)

but this does not what i want it to, in fact it doesn't seem
to do anything yet - probably because i'm using the wrong way :)

any hints how to do this correctly would be greatly appreciated.

thank you very much in advance and best regards,
Jürgen Herrmann

"dynamic" dtml-with from string content

Dear all,

has somebody an idea here?:

I try to define a property "my_class_path" (string) on a folder and want to 
use that within a dtml-with statement - i.e.:

my_class_path is i.e. "folder1.folder_sub"

<dtml-with "folder1.folder_sub">

seems to work, but i cant find any easy way to  to use the content of the 
string my_class_path within the with statement.

If i just have a single folder to get aquisition from, i just can use 
something like:

 <dtml-with "_[my_class_path]">

but if i have deeper pathes in my_class_path the this doesnt work.

I just can do directly:

  <dtml-with "_['folder1']['folder_sub']">

but i can't just put "_['folder1']['folder_sub']" into my_class_path too - 
this didn't works too...

It seems i have some tomatoes on my eyes. Can anyone push me back on the track 
here?

Many thanks in advance...

best regards,

Niels.

ANN: eGenix mxODBC Zope Database Adapter 2.0.2

________________________________________________________________________
ANNOUNCEMENT

                     mxODBC Zope Database Adapter

                            Version 2.0.2

                     for Zope and the Plone CMS

                Available for Zope 2.10 and later on
        Windows, Linux, Mac OS X, FreeBSD and other platforms

This announcement is also available on our web-site for online reading:
http://www.egenix.com/company/news/eGenix-mxODBC-Zope-DA-2.0.2-GA.html

________________________________________________________________________
INTRODUCTION

The eGenix mxODBC Zope Database Adapter allows you to easily connect
your Zope or Plone installation to just about any database backend on
the market today, giving you the reliability of the commercially
supported eGenix product mxODBC and the flexibility of the ODBC
standard as middle-tier architecture.

The mxODBC Zope Database Adapter is highly portable, just like Zope
itself and provides a high performance interface to all your ODBC data
sources, using a single well-supported interface on Windows, Linux,
Mac OS X, FreeBSD and other platforms.

This makes it ideal for deployment in ZEO Clusters and Zope hosting
environments where stability and high performance are a top priority,
establishing an excellent basis and scalable solution for your Plone
CMS.

Product page:

    http://www.egenix.com/products/zope/mxODBCZopeDA/

________________________________________________________________________
NEWS

We are pleased to announce a new version 2.0.2 of our mxODBC Zope DA
product.

With the patch level 2.0.2 release we have updated the integrated
mxODBC Python Extension to the latest 3.1.1 release, which
includes a number of important workarounds for these ODBC drivers:

 * Oracle 10gR1 and 10gR2
 * Oracle 11gR1 and 11gR2
 * Teradata 13
 * Netezza

Due to popular demand, we have also added instructions on how to
install mxODBC Zope DA 2.0 with Plone 4.1 and Zope 2.13 - even though
this combination is not officially supported by the mxODBC Zope DA 2.0
series:

    http://www.egenix.com/products/zope/mxODBCZopeDA/#Installation

________________________________________________________________________
UPGRADING

Licenses purchased for version 2.0.x of the mxODBC Zope DA will continue
to work with the 2.0.2 patch level release.

Licenses purchased for version 1.0.x of the mxODBC Zope DA will not
work with version 2.0. More information about available licenses
is available on the product page:

    http://www.egenix.com/products/zope/mxODBCZopeDA/#Licensing

Compared to the popular mxODBC Zope DA 1.0, version 2.0 offers
these enhancements:

 * Includes mxODBC 3.1 with updated support for many current ODBC
   drivers, giving you more portability and features for a wider
   range of database backends.

 * Mac OS X 10.6 (Snow Leopard) support.

 * Plone 3.2, 3.3, 4.0 support. Plone 4.1 works as well.

 * Zope 2.10, 2.11, 2.12 support. Zope 2.13 works as well.

 * Python 2.4 - 2.6 support.

 * Zero maintenance support to automatically reconnect the
   Zope connection after a network or database problem.

 * More flexible Unicode support with options to work with
   pure Unicode, plain strings or mixed setups - even for
   databases that don't support Unicode

 * Automatic and transparent text encoding and decoding

 * More flexible date/time support including options to work
   with Python datetime objects, mxDateTime, strings or tuples

 * New decimal support to have the Zope DA return decimal
   column values using Python's decimal objects.

 * Fully eggified to simplify easy_install and zc.buildout based
   installation

enhancements to RAM cache manager product

Greetings,

ram cached pages using the ram cache manager product seems to be a nice way to improve response times. 

As far as I remember it did not work well with ZEO.

Is there any merit to reengineering this product to use memcached as the backend instead of ZODB/ZEO ?

If so would anyone have an interest to work on this as a funded project ?

It will be great to hear about newer and better solutions as well.

Regards
