[Zope-dev] Zope 2.4: Unicode, Berkeley Storage?
I was just reading the Zope 2.4.0 plan on dev.zope.org, and I have two questions: 1. Will Unicode be supported (UTF-8 encoding) for results, posted data, marshaled arguments, etc? 2. Will the BDB storage be standard with 2.4? Transactional Undo sounds _very_ nice.

RE: [Zope-dev] ZEO on SMP
If I understand your scenario, you are trying to run two instances of Zope on a single machine, talking to a ZEO server? That won't work :) Neither Unix nor Windows knows what to do with two processes trying to open the same port for listen. I'm surprised the second Zope instance even starts. If you want to try it, start each instance of Zope on different ports, then use some kind of ipforwarding/load balancer on the box to route connections to port 80 to either of your Zope servers (say 8081 and 8082). -Randy -Original Message- From: Dyon Balding [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 23, 2001 12:08 PM To: Tino Wildenhain Cc: [EMAIL PROTECTED] Subject: Re: [Zope-dev] ZEO on SMP Tino, Thanks for your reply.

[Zope-dev] External transaction integration bug?
I may just be missing something obvious here, but it seems like there is a hole in ZODB.Transaction.Transaction.commit and Shared.DC.ZRDB.TM.TM, that can cause external transactions (those that use the TM mixin class, like psycopg) to be abandoned (never get committed or rolled back). Let's say somewhere around line 300 in Transaction.py (the call to j.commit(o, self)) we get an exception. Furthermore, let's say the TM derived database object has already been committed (the only effect of which is to move the DB into the jars mapping, since TM.tpc_begin() and TM.commit() both do nothing). The exception dumps us down to about line 353, where we call _p_jar.abort() on all the uncommitted objects (note: it's important that the database connection isn't in this list, because TM.abort() will rollback the transaction. the way we keep the db out of this list is by having it appear in objects _before_ the object that failed the commit). Next we reach line ~366, where we should "unwind TPC for the jars that began it". What this means is calling tpc_abort() on each jar from the objects that were already committed (which includes the database). However, TM.tpc_abort() does nothing, leaving the external database transaction open. Does this make sense? If this makes sense (i.e. seems bad :), does catching tpc_abort() in TM and calling TM.abort() seem like a valid fix?

RE: [Zope-dev] Objects, Roles and Permissions
I haven't worked with this code closely in a few months, but as I recall
permissions that are acquired are stored as a list, and those that
aren't are stored as a tuple.
if type(self._View_Permission) == type(()):
# done, this permission isn't acquired above this point
Furthermore, I may be missing the point of this thread, but if you are
trying to get the list of all roles assigned to a permission (from a
python product), you could use this:
from AccessControl.PermissionRole import rolesFromPermissionOn
roles = rolesFromPermissionOn('View', ob)

A "getGrantedPermissions" for examining a role should work
similarly, right?

set all to 1 and then... iterate through the list (tuple or
list? list of

the role?
Thx once again,

btw: Isn't return['Manager'] at the end of your code obsolete
(but safe)? Or
is there anything special going on at the root level
(isTopLevelPrincipiaApplicationObject)?

[Zope-dev] Zope 2.3.0 AccessControl/SecurityInfo.py
Sorry if these have already been fixed in 2.3.1, I haven't had time to
upgrade yet.
I fixed a small bug in SecurityInfo that made
SecurityInfo.setPermissionDefault() impossible to use:
191c191
self.roles[permission_name] = rdict.keys()
---
self.roles[permission_name] = rdict
def setPermissionDefault(self, permission_name, roles):
"""Declare default roles for a permission"""
rdict = {}
for role in roles:
rdict[role] = 1
if self.roles.get(permission_name, rdict) != rdict:
LOG('SecurityInfo', WARNING, 'Conflicting default role'
'declarations for permission "%s"' % permission_name)
self._warnings = 1
self.roles[permission_name] = rdict.keys()
My other problem was that I wanted to setup some default permissions
that are used programatically in my product (i.e. they aren't used to
protect any specific methods, but the methods themselves check for the
permission.) A small change to ClassSecurityInfo.apply() allows you to
call SecurityInfo.setPermissionDefault() to create new permissions, even
if they aren't attached to any methods:
239a240,242
for permission_name in self.roles.keys():
if not ac_permissions.has_key(permission_name):
ac_permissions[permission_name] = ()
def apply(self, classobj):
"""Apply security information to the given class object."""
dict = classobj.__dict__
# Check the class for an existing __ac_permissions__ and
# incorporate that if present to support older classes or
# classes that haven't fully switched to using SecurityInfo.
if dict.has_key('__ac_permissions__'):
for item in dict['__ac_permissions__']:
permission_name = item[0]
self._setaccess(item[1], permission_name)
if len(item) 2:
self.setDefaultRoles(permission_name, item[2])
# Set __roles__ for attributes declared public or private.
# Collect protected attribute names in ac_permissions.

ac_permissions[access].append(name)
# Now transform our nested dict structure into the nested tuple
# structure expected of __ac_permissions__ attributes and set
# it on the class object.
getRoles = self.roles.get
__ac_permissions__ = []
for permission_name in self.roles.keys():
if not ac_permissions.has_key(permission_name):
ac_permissions[permission_name] = ()

[Zope] CoreSessionTracking and ConflictError
I've been porting my product from my own private session manager to use
CoreSessionTracking 0.6, and am having a problem with lots of conflict
errors.
I've got a session_id_mgr in the root, configured as per defaults, and a
session_data_mgr also in the root, using the RAM base container.
Then I have a simple DTML method:
dtml-let session="session_data_mgr.getSessionData()"
dtml-let title=title
dtml-call expr="session.set('title', title)"
dtml-in expr="_.range(100)"
dtml-in expr="_.range(100)"
/dtml-in
/dtml-in
/dtml-let
/dtml-let
Test
If I goto this URL in a browser, it works fine, displaying "Test", with
no ConflictError in my debug listing. Then I quickly press Refresh
twice in my browser. This results in the page "Test", and a
ConflictError in my log (as I expected).
After that, any request that uses the session data (even without a set)
results in a ConflictError:
dtml-let session="session_data_mgr.getSessionData()"
Title: dtml-var expr="session.get('title')"
/dtml-let
Any ideas why this is happening?

RE: [Zope] hasRole bug or feature in 2.2.?
From: Ron Bickers [mailto:[EMAIL PROTECTED]]
If this is true, it explains clearly Zope's behavior. It's really a
browser
"feature" and not a Zope issue at all.
Yes, that's the problem.
My solution is to use a custom UserFolder, which sets a temporary cookie
when a normal HTTP login is accepted. This cookie is then used for
further validation. The class I use is rather complex, providing
persistent login in addition to these features, and randomly re-creating
the cookie so one can't easily spoof a user, but this simple class will
get you going:
class UserFolder(AccessControl.User.BasicUserFolder):
def validate(self, request, auth='', roles=None):
user = AccessControl.User.BasicUserFolder.validate(self,
request, auth, roles)
if user is AccessControl.User.nobody or user is None:
if request.cookies.has_key('login'):
user =
self.getUser(request.cookies['login'])
else:
request.response.setCookie('login',
user.getUserName(), path='/')
return user

Subject: [Zope] Using a multiple_selection property in a product
I am attempting to build a product that will contain some unique
information and access control for services in support of college
classes. Many, many things are going well...better than expected.
However I am having problems getting the product to correctly recognize
a multiple selection property. The property is the days of the week that
the course is offered. ( Monday-Wednesday-Friday or Tuesday-Thursday, or
any combination thereof)
The DTML for the product creation form contains the following:
---
th align="LEFT" valign="TOP"emDays Course Offered/em/th
td align="LEFT" valign="TOP"
select name="classdays:multiple_selection" size=5 multiple
option value="Monday"Monday/option
option value="Tuesday"Tuesday/option
option value="Wednesday"Wednesday/option
option value="Thursday"Thursday/option
option value="Friday"Friday/option
/select
in the product class I have tried two tactics (actually more but I'll
confess to only these two)
_properties(
{'id':'classdays',
'type':'multiple_selection','mode':'w'}, ...
RESULT: product installs, but classdays in an "unknown property type"
so I try this:
_properties(
{'id':'classdays', 'type':'multiple
selection','mode':'w'}, ...
RESULT: product installs, however the Properties are unavailable,
furthermore trying to view the properties by clicking on the Properties
tab generates the following Zope error:
Error Type: NameError
Error Value: select_variable
[somewhat helpful troubleshooting suggestions]

I've also tried to use :list with much less success. Any helpful
suggestions would be appreciated. The solution is not obvious to me.
TIA...

RE: [Zope] RE: New install - no management screen? (resolved)
I realize you've already worked around this problem, but I've seen this on some installations of IE. The solution I've found is to delete all cookies from the client. -Randy -Original Message- From: Glenn Gillis [mailto:[EMAIL PROTECTED]] Sent: Sunday, December 31, 2000 8:57 AM To: [EMAIL PROTECTED] Subject: [Zope] RE: New install - no management screen? (resolved) Thanks for the suggestions. It turns out to have been an Internet Explorer thing. I pulled the site up in Netscape and everything works fine. I was on IE 5.01 SP1, upgrading to 5.5 SP1 seems to have resolved the problem. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev ) ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] custom __of__
This is something that I still don't quite understand. I have a set of (python, Folder derived) objects, which are children of a Folder derived python class. Each of these in turn has another, related python object. / a ab1 ab2 ab3 b1 b2 b3 When I access /a/ab1, I want b1 inserted into the acquisition hierarchy between a and ab1. I've done this with __bobo_traverse__, but that doesn't help when you access ab1 as an attribute of a, such as when using objectValues(). So I thought I would try overriding __of__, like so in the ab class: def __of__(self, parent): wparent = self._b.__of__(parent) return Folder.Folder.__of__(self, wparent) But that doesn't work, I get this error on the return line: Error Type: TypeError Error Value: unbound C method must be called with Acquirer 1st argument Any ideas? I'm pretty confused.
