At the time I was involved the implementation came up short of anything useful and was prone to crashing the server. 2 of the bugs I filed at the time are still listed as 'open', and IIRC I didn't get round to filing a bug for everything I found (I communicated those to Robert directly).

Indeed, especially because no type can be "None"! It is known that refreshing (more generally reloading a Python module) can cause objects apparently becoming "None". This happens because the variables defined in the old module instance are rebound to None when the module is released. This would explain that "aq_parent" in your "index_html" would appear as None if you happen to access an object still associated with the old class. However, the type of "None" is "NoneType" and not "None". I do not yet know what magic can cause "type(aq_parent)" (which usually is ") to become "None". As written earlier: refreshing is essentially a Python feature (delete a set of modules from "sys.modules", then reimport some of them again) rather than a Zope feature. It should be possible to reproduce your weird observations with Python operations only. I tried but was not yet able to reproduce it (I still use Zope 2.8 (but that should not matter) and Python 2.4.1). -- Dieter ___ 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 )

Sounds like you have your Apache setup misconfigured, and it is not passing along the cookies. Use a Firefox extension like LiveHTTPHeaders or the Web Developer Toolbar to see what Cookie headers are being sent back and forth to see if Apache is handling things correctly.

Re: [Zope] Product refreshing in Zope 2.9
I've noticed another strange behaviour with the Acquisition module in Zope 2.9 that might give us some clues as to why refreshing doesn't work. Imagine some code that looks like this:: from Acquisition import aq_parent class MyProduct(Folder): def index_html(self): print type(aq_parent) is None return "Hello World!" The first time I run this, it prints "False" to stdout because ac_parent is of course a function. BUT, if I refresh the product (no change made to the source) and run this index_html() again it instead prints "True" because ac_parent has become None. Isn't that odd? Again, this is easily reproducable with http://www.peterbe.com/zope/2.9-refresh-reproduction/MyProduct.tgz Any idea anyone?

Yes it works; we have some stuff working here at my place of employment. I had some problems getting the right squid build to work last year when looking at this for a customer, but since the team here has had no problems that I'm aware of with current builds.

I don't agree that refresh is "crucial": refresh has always had "best effort" semantics, which leads many experienced Zope2 developers never to use it at all. Through bitter experience, they have learned that when refresht fails (silently), they have found that the hours spent figuring out why the application's behavior changed are much more expensive than the time it takes enter '' in the zopectl shell. You'd be better off lobbying for faster restart times, including especially the third party products you use (a "stock" Zope restarts *very* quickly).

Python product refresh is crucial to zope2 and this problem needs to be sorted out. I'm calling bullshit on this one. How is it "crucial"? A product that introduces its own strange problems cannot be called "crucial".

You also need to reload all products that import this product, and (as I think was mentioned before) if you use any kind of global registy it will most likely fail.
