[Zope] Pword reset tools

[Richard Harley]

It looks like there are no pa55word reset products for straight Zope that are 
still maintained i.e. a feature to allow users to reset their own pa55words via 
email linking into aclusers.

If that is correct does anybody have any pointers for implementing such a 
mechanism with a one time email reset tool?

TIA

Re: [Zope] Zope and security vulnerability: 20121106

So, to clarify, does this affect plain Zope 2.10, no Plone?

The affected versions go back a long time. I don't know it exactly,
but people have used it successfully with Plone 2.1 (from ancient
times) and I have patched Zope 2.8 instances too.

Hi,
is a standard Zope affected by this security vulnerability or
only if Plone is installed:

The patch is replacing some basic classes therefore it looks to
me that Zope itself without any Plone is vulnerable too. If so
is there a Hotfix for Zope or new Zope version which fixes these
bugs?
Ciao Marcus

Re: [Zope] Python scripts

That works great, thanks. So there is no way to do this across, say, a 
folder with hundreds of scripts in without duplicating the code in each 
individually?

You can check that the script is not the published object with:

 if container.REQUEST['PUBLISHED'] is script:
 raise 'Forbidden'

For newer versions of Zope raise an exception object:

 from zExceptions import Forbidden
 if container.REQUEST['PUBLISHED'] is script:
 raise Forbidden('Script may not be published.')

Does anyone have a recommendation on how to implement sessioning on Zope

[Zope] Python Script Security

[Richard Harley]

Hello all

I have a dtml method which builds a page from various different python 
scripts.
How can I stop the python scripts from being called and passed variables 
independently of the main dtml method? I've tried some research on proxy 
roles but couldn't pin it down.  ZSQL methods are not callable 
independently and I would like Python Scripts to behave the same.
TIA

[Zope] zopetime behaviour

[Richard Harley]

Hi all

I hope I'm not missing something obvious here. ZopeTime is gaining two 
hours when it's string formatted.

*
thistime = context.ZopeTime().strftime("%Y/%m/%d %H:%M:%S")
print "ZopeTime:"
print context.ZopeTime()

print "String formatted ZopeTime:"
print thistime
*

The output is this:*

*ZopeTime: 2011/09/20 10:16:12.628 GMT+1

String formatted ZopeTime: 2011/09/20 12:16:12

How come string formatted ZopeTime gains two hours?

Cheers

[Zope] AUTHENTICATED_USER

[Richard Harley]

Please could someone tell me why AUTHENTICATED_USER was deprecated in 
favour of the python security module? A quick google says "because it 
can be replaced"..but this isn't really a good in depth explanation? If 
a request was manipulated to include another AUTHENTICATED_USER, 
wouldn't Zope just error out anyway?

Re: [Zope] Zope Dates

Thanks Andreas - so there is no way to set a date format at an 
intermediate layer so that all dates are rendered a certain way without 
string formatting? Am I naive in thinking this could possibly be done at 
the db adapter level?

'international' only affects the format for parsing dates as far as I
can recall. Using strftime() gives you full control over the output
format. Your application should not rely on the default format. If you
need a custom date output format then define it explicitly in your
application.

Re: [Zope] Question about Upgrading Zope and OS X Server

[Richard Harley]

Dan - we are using 64bit Zope 2.8.7 and python 2.4 with no problems for 
years now. It can do everything we want with regards to Python 
scripting, database connectivity etc.

I can't think of any huge problems with staying on Zope 2.8.6/7 era. I 
have said before 2.10+ breaks lots of products that would take ages to 
hack about (especially for companies using Zope not individuals with 
time on their hands). I'm all for upgrading, bug fixing and refactoring 
normally, but the backwards compatibility with Zope makes it harder than 
it should be.

Re: [Zope] Zip Folder

[Richard Harley]

OK thanks, I'll have a look. I didn't want to waste time hacking around 
old products initially. I guess there's not much demand for this then, 
because it would have been done and released otherwise. I'm surprised 
it's not a staple part of a zope installation though.

[Zope] Zip Folder

[Richard Harley]

Hello all

I have been using Zope 2.9 - which works with the zip folder product. 
Now I upgraded to Zope 2.13 but the zip folder product does not work. Is 
there an equivalent, or another way of unzipping folders straight into 
the filesystem?

Thanks

[Zope] Logging a user onto zope

[Richard Harley]

Hello all

I'm trying to log someone onto Zope not using acl_users - how does this 
work? Ideally I want to pass variables through a logon page, 
authenticate against a postgres table then let the user have access to a 
certain folder. I tried ExUserFolder but it seems over the top for what 
I want and very dtml-heavy.

[Zope] commit problems psycopg

[Richard Harley]

  We have had a problem with postgresql 8.3 on a Windows server 2008. I
  wonder whether there has been any other experiences like this. We have
  connected to Potsgres from Zope via a Psycopg adapter and noticed that
  sometimes when data is inserted via a form in Zope, the data is
  available in Zope but doesn't get committed to the database. This has
  come to a head over the weekend where at least one month's worth of data
  has disappeared and this includes changes to the actual database
  structure - luckily only on a testing machine, but concerning nevertheless.
  The data seemed to disappear after we upgraded to the most recent
  version of Zpsycopg2 database adapter, previously we were using version
  1 (I know it's old, we are only testing after all) and have never had
  these sorts of problem before. It's almost as if all the data and
  changes to the db were held in memory, and Postgres continued to work
  fine from there, but when the db adapter was changed and Zope restarted
  everything was cleared from memory.
  Has anyone had similar experiences or can anyone cast any light on where
  the problem may lie. To us it seems the db adapter is the most likely
  candidate but we can't understand how this could happen, explanations
  also welcome. Have posted this to psycopg list too.
Thanks
