Re: [Zope] Firefox manage_changePermissions issue?
Hi Tony, Sory for the age in replying... Tony Addyman wrote: Chris: Can you recall whose Firefox you would have been using at the time? I have been using the RPM version from SUSE 9.2. I would have been using a recent Windows binary. The problem occurs a number of times when using POST with the ZMI. The major changePermissions problem is just the most obvious. When the problem occurs elsewhere simply repeating the interaction within the ZMI makes the change "stick" eventually, i.e. the POST is not followed by the phantom GET. I have just started using the stock tar.gz firefox installer from mozilla.org. So far it hasn't shown the problem. Of course, the problem doesn't always occur, but it may be progress. Yeah, sadly, after my initial experience with something that may have been caused by this, but which I never actually tracked down, I haven't bumped into it again, even though I'm almost exclusively using Firefox now... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk ___ 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 )

(snip) I have not been able to provoke anything similar with Firefox 1.03 and CMFDefault 1.4.2 which is what I had handy when I read your message. You might try Shane's tcpwatch.py to further analyze the problem: Start it like e.g. (if zope is running on http://fooserver:8080): tcpwatch.py -h -L :fooserver:8080 then point your browser at http://localhost: and tcpwatch will log *everything* that goes between server and browser - all request data, all response headers and data. -- Paul Winkler http://www.slinkp.com ___ 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 )

Anyone got any ideas on how to stop Firefox doing this? ;-) cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk ___ 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] Firefox manage_changePermissions issue?
I have experienced the following problem on two separate Zope/Plone sites. It is reasonably repeatable, but sometimes works without problem. I have a ZODB saved for testing purposes. I have tried fsrecovery.py on the database. It is not corrupted. Firefox fails on this database every time. The scenario: I change a permission setting using the ZMI of a Plone Site. I press the Save Changes button. Firefox sends a POST .../manage_changePermissions message to make the required change. A 200 response is returned. Firefox then immediately sends a GET .../manage_changePermissions without any interaction from the user. This totally destroys the permission settings for the object. Naturally, two transactions are logged, and undoing the second one fixes the error. However, it took over a day of digging to work this out, and the error is quite heart-stopping when it hits, because you are locked out of the object - in my case the entire Plone site. I can make this behaviour occur with Firefox repeatedly, but not quite always. If I continue to work on a site making changes and undoing them, sometimes the manage_changePermissions is only sent once. If I return to the "saved" ZODB and restart Zope, the duplicate sending happens in Firefox without fail. I have tried both Firefox-1.0.1 and Firefox-1.0.3. I have not managed to make it happen with Mozilla-1.7.2 or Konqueror-3.3.0, but I have been using Firefox most of the time because of the Live HTTP Headers extension. I have the logs, HTTP messages between browser and server, etc. I can't see anything in the Zope Access Control source which would cause a GET to be used after the POST. The GET is logged in the Firefox Live HTTP Headers, so it is not being generated further down the line by a proxy. I have a solution to apply next time this happens (use undo), but I would really like to track this one down. Any suggestions as to what to try next? I don't really want to study the Firefox source. I would rather learn about Zope and Plone :-) Thanks Tony Addyman -- Eur Ing A.M.Addyman, School of Computing, Science and Engineering University of Salford, Salford, M5 4WT ___ 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 )
