[Zope-dev] No more access to username
Hello!
Until Zope 2.8.3 it was possible to access to the name of the logged in
user also in a public accessible method. A thing I used quite often is
hiding links which were not accessible for an anonymous user but show
them in case the user has authenticated itself somewhere else in the site:
dtml-if AUTHENTICATED_USER.has_role('Manager')
| a href=manageManage/a
/dtml-if
This no longer works in Zope 2.8.5 (2.8.4 is untested) and Zope 2.9.0.
AUTHENTICATED_USER or _.SecurityGetUser().getUserName() is set to
Anonymous User as long as the method does not require a login. When a
login is reqired, AUTHENTICATED_USER is filled correctly but a
unpriviledged user is no longer able to access the document.
I'm not sure if I should see this as a bug or a feature and I was not
able to find the change in a diff of the sources. Could you tell me more
about this behavior?
Beat

[Zope-dev] Nine new ZC Zope 3 packages on zope.org
Zope Corp has released nine new packages as standalone Zope 3 projects on zope.org. Three are completely new to the zope.org repository, and six were previously part of the zc Sandbox on zope.org. These three packages are brand new to zope.org. zc.shortcut Our (second) take on the symbolic link use case. zc.displayname What we use for drawing breadcrumbs and such; a dependency of zc.shortcut. zc.relationship A very new cut at a ZODB-friendly directed graph, based loosely on some old ZC work. These next six projects were already in the zc sandbox, and are now moved to full-fledged projects so collaboration is possible and so we share the state of the art. zc.datetimewidget A datetime widget that uses the now-standard mishoo LGPL calendar widget. zc.extrinsicreference One-way references designed to be back-references for standard attribute pointers. zc.form Some *extremely* useful but sometimes undertested widgets, including timezone widgets and choice widgets that remember the last chosen value per user. zc.listcontainer A persistent linked list that might be more appropriate than ordered container for some use cases. Well tested. zc.resourcelibrary An approach to letting page components dynamically request javascript and css resources during page composition. Wants a publishing pipeline to be able to get rid of a heavy-handed replacement of the browser request factory. Good idea, usable and useful now, but could use more polish. zc.table A very useful and powerful table rendering implementation, including the ability to have table-based forms. It has some rough edges that could use polish. ZC has released many other useful standalone projects on zope.org over the past few months, including zope.file, zope.ucol, zope.locking, and zc.catalog. They all are worth a look.

[Zope] ZEO disconnects, Zope auto restarts (via zopectl)
Zope 2.9.0 We are seeing spontaneous restarts of Zope with no indication in any of the standard Zope logs. Looking at the ZEO log indicates that the restarts of Zope are due to a lost connection between Zope ZEO but with no other information. The logging level is set at the distribution default (INFO). The restarts are a huge problem because session variables are not persistent and so all of the user state they contain is lost on restart. In our statful implementation, this is a major problem. I want to adjust the configuration so that the Zope/ZEO connection is stable. In our configuration, Zope and ZEO are linked via localhost on a distinguished port. I've Googled about looking for some infomation about tuning the ZEO/Zope interface, but have found little real information. Some additional log detail would be helpful. We are running a fairly vanilla setup, excerpted below: zope.conf # ZEO client storage: # zodb_db main mount-point / # ZODB cache, in number of objects cache-size 5000 zeoclient server localhost:8301 storage 1 var $INSTANCE/var # ZEO client cache, in bytes cache-size 20MB # Uncomment to have a persistent disk cache client group1-zeo /zeoclient /zodb_db zeo.conf zeo address localhost:8301 read-only false invalidation-queue-size 100 pid-filename $INSTANCE/var/ZEO.pid # monitor-address PORT # transaction-timeout SECONDS /zeo runner program $INSTANCE/bin/runzeo socket-name $INSTANCE/etc/zeo.zdsock daemon true forever false backoff-limit 10 exit-codes 0, 2 directory $INSTANCE default-to-interactive true # user zope python /usr/bin/python2.4 zdrun /usr/local/src/zope/Zope2.9/lib64/python/zdaemon/zdrun.py # This logfile should match the one in the zeo.conf file. # It is used by zdctl's logtail command, zdrun/zdctl doesn't write it. logfile $INSTANCE/log/zeo.log /runner It's not clear what changes will lead to a more stable connection because it is not clear what's triggering the problem. Any advice would be appreciated. Presumably the shotgun approach would work -- increase the cache sizes, lengthen the invalidation-queue-size, and increase the backoff-limit but it would be nice to have some guidance. 5~ ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

[Zope] inheritance and aqusition question
Hello,
im just learning zope and python and find it difficult to get the details of
aquisition and inheritance.
I have the following problem:
(FS product)
My base class has an attribute manage_editSettingsForm
In its __init__ method I instantiate a contoller class.
In the methods of the controller class can access self.manage_edtiSettingsForm
(fine)
Now I instantiate a importSingle class in a method of the controller class.
In the methods of the importSingle class I cannot access
self.manage_edtiSettingsForm (why?)
Controller class:
from Acquisition import Implicit
from Globals import InitializeClass, Persistent
from Products.PythonScripts.Utility import allow_class, allow_module
from AccessControl import ClassSecurityInfo
from OFS.SimpleItem import SimpleItem
from OFS.ObjectManager import ObjectManager
from Products.BTreeFolder2.BTreeFolder2 import BTreeFolder2
from Lasttest import Lasttest
import sys, os, urllib, commands, re, types
import LTimport
allow_module=('Controller')
class Controller(Implicit,ObjectManager, SimpleItem):
-
importSingle Class:
from Globals import InitializeClass
from Acquisition import Implicit
import os,re
class importSingle(Implicit):
I tried subclassing form SimpleItem and ObjectManager but it didn't work.
What is required that inheritance will work?
Greetings Roman

That's true! And it's nor supposed to be. It's only a temporary Object that's
being destroyed
after the method in which it's created has finished processing.

'post init' method to do a 2-stage init so that subitems can acquire items.

Acquisition to work in this way.
I wouldn't like to do that either, because I don't want that object to persist.
Probably I just do things in the wrong way. What I wnat to do is:
In the temporary object:
try:
h=open('file',r)
except:
em = 'File %s does not exist' % file
return REQUEST.RESPONSE.redirect(self.manage_editSettings(REQUEST), em)
the calling Object then would pass it to the browser ...
... in order to do some exception handling.
is there an other way to redirect to the settigs Form when an error occurs in
this nonpersistent object?

Hello Andrew,

One (or more) of the following two;

That's true! And it's nor supposed to be. It's only a temporary Object that's
being destroyed
after the method in which it's created has finished processing.
You generally need to use a
'post init' method to do a 2-stage init so that subitems can acquire items.
There are Zope hooks you can use (manage_afterAdd), or you can call your
own methods in the manage_add Factory method of your product.
If this is what you are doing then it's probably;
The importSingle class must be an attribute of the Controller class for
Acquisition to work in this way.
I wouldn't like to do that either, because I don't want that object to
persist.
Probably I just do things in the wrong way. What I wnat to do is:
In the temporary object:
try:
h=open('file',r)
except:
em = 'File %s does not exist' % file
return REQUEST.RESPONSE.redirect(self.manage_editSettings(REQUEST), em)
... and you want manage_editSettings to be acquired, ok.
As has been suggested, you probably don't have an acquisition
wrapper set up. You can create one without persisting
your wrapped object like so:
class Controller(...):
def some_method(self, ...):
...
temp = importSingle(...)
temp = temp.__of__(self) # this creates the wrapper
temp.someMethod()
...
Once you have a wrapper, you can call methods on it and
those methods can successfully acquire things from the acquisition
context (in this case the Controller instance).
This example assumes that your Controller is responsible for
instantiating the importSingle instances.
But having said that, I too wonder why use acquisition for this.
Why not just pass in a reference to the Controller instance
and call methods on it explicitly?
