RE: [Zope] apache open proxy configuration problem
Title: RE: [Zope] apache open proxy configuration problem
I abandoned mod_proxy for mod_rewrite. Security-wise, mod_rewrite had
less to worry about (this is important when website administration
changes hands).
The sample configuration below shows how to handle Zope resource
quirks and how to proxy requests to and from folders in Zope (both
tested). The last rule is my guess at what "proxy everything to and
from Zope" would look like (untested). Apache is listening on 80 and
routes requests to a Zope instance listening on 8080.

I've been running zope through apache for years and years now, and I
have a new machine set up with apache 2.0.48 and zope (Zope 2.8.0-final,
python 2.3.5, linux2)
Using Identical Vhost configuration settings from an old machine all has
been well, up until about 5 days ago, when I noticed the machine getting
slammed, and wierd logs started showing up like:

In my quick research to try to determine the problem, I found people
advising to turn "ProxyRequests Off", which I did, but did not have any
effect.
Luckily this is just a development server, not a live production server,
so its not super critical, but I'm nervous now that my production server
might be in the same state...

[Zope] Deleting objects from an external method
I'm trying to allow users to delete objects that have been accidentally created. I have criteria for what that means, but since I *DO NOT* want them to delete object except by this method, I want to avoid granting "Delete objects" to them (non-Managers). Can this even be done? At the base level, "Delete objects" is a hard-coded requirement of the ObjectManager.manage_delObjects() function. One solution that I considered is to create a new role with the privilege, then within my ExternalMethod: - grant the role to the user for the folder, - delete the object, - remove the role for that user for the folder But this seems overly tedious, and a problem if the script terminates before removing the role. Similarly, it could use the Manager role in the same scenario, but this seems dangerous.

All it means is that Python's `whrandom` module is going to go away in a future release -- it's advising applications to switch to using the `random` module if they want to continue to work under future releases.

The Zope concern for moving to any new Python release isn't that Python may be buggy, it's that a new Python release may introduce new behaviors that open "security holes" in Zope. Until a security audit is performed (which is done by expert humans), and any new security holes that may be discovered get plugged, 2.4.2 will remain unsupported for use with Zope 2. In contrast, Python 2.4 is now _required_ for Zope 3 development. Zope 3 has a different approach to security, which isn't as sensitive to changes in Python. ___ 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 )
Re: [Zope] resolving conflict errors
Thanks Chris. On point as usual! I was unaware that the session mechanism used the ZODB although a bit of thought says it has to. We don't store any data into the ZODB in these methods, but we do use the session mechanism heavily. I suppose that moving to a fully transactional database system would be the simplest solution, but I'm a bit wary of doing so on a live system.

The solution, of course, is to resolve the conflicts properly. Another solution is to use a RDBMS that fully supports transactions. This is almost always the easiest solution. ConflictErrors are a fact of life if you use ZODB to store data; they are impossible to eliminate entirely so no matter what, if you need to communicate with external data stores that aren't transactional (MyISAM tables, LDAP, sendmail, etc.) you need to anticipate duplicated requests in the code that communicates with these systems. For example, Jens Vagelpohl has a replacement for Zope's MailHost that prevents retried requests due to conflict errors from causing a mail to be resent. I've written payment systems that anticipate the fact that the request may be retried, so instead of submitting the payment request twice, the code keeps around a little cache about what it did "last" so it doesn't do it again. And so on. > The first question: what data is generating the conflict? I believe that if you run Zope event logging at BLATHER level, the traceback of every ConflictError exception is logged, which can give you an idea of what is causing the errors. > The DTML code > and all the method references are static and unchanged. What data does > Zope store in the ZODB when an object is evaluated? None that you don't tell it to. Typically conflict errors are a result of two threads calling code which changes the same object at the same time, but nothing that Zope does "under the hood" causes it; it is always caused by application code. One "exception" to this rule is conflict errors raised when using Zope sessions. It's not actually an exception to the rule, but programmers are shielded from the fact that sessions store data in ZODB when you use the session API (e.g. REQUEST.SESSION). The sessioning machinery needs to manage housekeeping info whenever the API is used to expire old sessions and create new ones, so although it may not "look" like you are writing to the ZODB when you use sessions (even to read data out of them), you potentially are. Zope 2.8 has a ZODB that support multiversion concurrency control, which eliminates a certain class of conflict errors (read conflict errors), so if you are getting a lot of these, and you can get away with using 2.8, I'd suggest doing so. > Presumably conflicts can be reolved programatically by setting a method > on the object > >_p_resolveConflict( self, old, saved, new ) > > and returning one or another of the states (old, saved, new).

[Zope] resolving conflict errors
Zope 2.7.6 I am a bit confused. I have a Zope DTML method that is generating ZODB conflict errors. The DTML method identified as producing the conflicts is a list of calls to other methods, conditionally executed. Most conflicts don't cause problems because the backoff and restart of the initial transaction will not have changed global state. In our particular case, the conflicting transaction has changed global state in our RDBMS so when it gets rerun, some RDBMS transactions are duplicated. And that's a problem. The solution, of course, is to resolve the conflicts properly. The first question: what data is generating the conflict? The DTML code and all the method references are static and unchanged. What data does Zope store in the ZODB when an object is evaluated? Presumably conflicts can be reolved programatically by setting a method on the object _p_resolveConflict( self, old, saved, new ) and returning one or another of the states (old, saved, new). It's not real clear how to do it. -- ___ 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 )

Uncomment it. jens ___ 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] __getitem__ and returning a PageTemplateFile instance
Hi,
I am trying to make a product where-in I want to be able to return a
page based on the url, think something like /product/username
which would return a page with the users details.
For this purpose I am using __getitem__, but when I return a
PageTemplateFile instance it just tells me it has encountered a problem
publishing the object.
Example:
class TestProd(SimpleItem):
"""A TestProd object"""
meta_type = "TestProd"
manage_options = ( {"label": "Edit", "action": "manage_main"},
{"label": "View", "action": "index_html"})
manage_main = PageTemplateFile("templates/mainTestProd", globals())
index_html = PageTemplateFile("templates/indexTestProd", globals())
userdetails = PageTemplateFile("templates/userdetails", globals())
def __init__(self, id, title):
self.id = id
self.title = title
def __getitem__(self, id):
# Does not work!
results = fetch_userdata_from_db(id)
return self.userdetails(self, self.REQUEST, results=results)
def test(self, username):
# Works, but uses /product/test?username=username
results = fetch_userdata_from_db(username)
return self.userdetails(self, self.REQUEST, results=results)
I have tried with everything I can think of to debug this, but have so
far failed. What am I doing wrong here?
Please note that I have also tried with static data, that is returning
self.userdata(self, self.REQUEST, results="some data")

VerboseSecurity is *integrated* into Zope after 2.8, you don't install it separately. You enable it in zope.conf, see the "verbose- security" option. jens ___ 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 )
Re: [Zope] error trying to import smtplib (unauthorized)
*continues banging head against brick wall* My friend you have made me an official MailTemplate product beta tester ;-) Because it has no security declarations. If you bothered to install VerboseSecurity it would have told you this... MailHosts are how you send mail in Zope... MailTemplates are what you want to use, I still don't understand why you're having so many problems, I simply cannot reproduce what you're seeing... Start with a fresh, clean Zope instance and tell me the steps you go (every single one of them!) through to get to the point where you can try the python script and get the errors you were complaining about before... cheers, Chris FINALLY it work's! I installed VerboseSecurity and repeat the same action'sit just work. Sorry for the delay Chris but I read some where that VerboseSecurity is made only for Zope 2.7 and some users recommend not to install that product because it changes the security policies of zope with the authors ... Thanks for the help Chris (and for the product ;-) ). NOTE: With VerboseSecurity installed there is no need to change any permission in any object or folder on the security tab to get the product run. ___ 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 )

Is there any way to return the "data" encoded in utf-8? It is
coming as
ISO-8859-7 from an SQL2K Server...
utf8_string = unicode(iso_8859_7_string, 'iso-8859-7').encode('utf-8')

No, you haven't anyway taken me through, step by step, what you've
done to get where you are...
What release of Zope are you using?
Chris
I unistall zope and install it again with version Zope-2.8.2-final and
put your product on C:\Zope-Instance\Products\MailTemplates
I run Zope with admin priviledges and :
1.Created a folder with id MailTesting on the root.
2.Created a MailHost object with id MailHost inside MailTesting folder.
3.Created a MailTemplate object with the id my_mt and selected my
MailHost object (from step 2) inside MailTesting folder.
4.Created a python script inside MailTesting folder with the id
send_mail and change your code only in the part :
mto=('[EMAIL PROTECTED]',[EMAIL PROTECTED]), --> mto='[EMAIL PROTECTED]',
5.Created a file with the id myfile.bin and loaded a txt file inside
MailTesting folder.
6.Have changed in _all objects_ and in the _folder_ the _permissions_ on
the security tab of each one (_I checked all the checkboxes!!!_)
7.Try to run the python script from the test tab ... :
It prompt for user name and password.
User name and password given correct and it keep prompting the same.
Some how this action log me out from Zope.
8.To check the error log I must log in again.There are 2 errors :
A) admin (admin) Unauthorized: You are not allowed to access 'add_file'
in this context
(when I was trying to test the script with my account )
B) Anonymous User (None) Unauthorized: You are not authorized to
access this resource.
(when I log on again to see the error log)
traceback for A:
Traceback (innermost last):

9.If I press cancel when I run the python script your product show me
this error message:
Error Type: Unauthorized
Error Value: You are not allowed to access 'add_file' in this
context
Is that what you want ?
I will install VerboseSecurity (my last hope)
