[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.

I can successfully run two Zope (non-ZEO) processes on a single machine, but two ZEO clients don't seem to coexist nicely on the Windows 2000 machine.

[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)

Subject: Re: [Zope-dev] Objects, Roles and Permissions
Thank you very much, Richard! Cool!
Still...

Feel free to expand the method to other roles
and the full suite of permissions.

Other *roles*? Roles are what's coming back, isn't it?
def viewPermissions(self, acquired=0):

"possibly _only_ the acquired permissions" - oops! Your
snippet worked fine
_if_ the view permission was acquired by that object. As soon
as I turned
off acquisition for the view permission of the object, it
would still give
me the acquired roles (that in fact were'nt acquired). What
does the "if"
statement look like that would return the object's own roles
for the View
Permission if acquisition was turned off? Naive Danny who
doesn't know s...
tried to put
if hasattr(self.aq_base, '_View_Permission'):
return self._View_Permission
at the beginning of your code, but no effect. :-(
But now I see how to access specific permissions and read
their content (do
I? I'll experiment with it), thank you very much! I will put a
string.replace on top and pass the Permission to examine by string
parameter, and call that whole stuff "getAllowedRoles".
A "getGrantedPermissions" for examining a role should work
similarly, right?
def ac_inherited_permissions(self, all=0):
set all to 1 and then... iterate through the list (tuple or
list? list of
tuples?) and check every "_current_Permission" if it contains
the role?
Thx once again,
Danny
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 = {}
for name, access in self.names.items():
if access in (ACCESS_PRIVATE, ACCESS_PUBLIC, ACCESS_NONE):
dict['%s__roles__' % name] = access
else:
if not ac_permissions.has_key(access):
ac_permissions[access] = []
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] = ()
permissions = ac_permissions.items()
permissions.sort()

roles = getRoles(permission_name, ())

entry = (permission_name, tuple(names))
