RE: [Zope-dev] Can't access ZClass object unless superuser
Steve rocks! It wasn't actually the Ownership, but when I looked at the object I realized that I did not expose the Ownership tab, or the Security tab for the objects that I had created from the ZClass. When I created those views, I found that the permissions for the objects were not set correctly. I don't know how that happened, since I could not even see the permissions in order to edit them. I assume that they acquired those permissions from somewhere, but far better to see them make sure they're right. 'View' and acquire permissions had been disabled. Thanks again!

Re: [Zope-dev] Re: Zope 2.4 crashes -- possible fix identified, other solutions also suggested
Matt et al - We are using python 2.1.1 with pymalloc disabled and gc enabled with zope 2.4.3 on the solaris platform. We are currently seeing only 1 or 2 restarts a day for the zope/zeo clients. Fortunately, we have not experienced any trouble with the zeo server. We have applied the a) extensionclass bugfix and I'm also planning to apply the b) frame setup bugfix later this week. We feel that patch a) has reduced the number of restarts ... but the site activity has descreased as well so it is difficult to really confirm. 1) I would like to know if any patches are available yet for the c) compiler stack size bug. When and if this patch is available, would it require a new python installation, a new zope installation, or both? 2) Are there any other related patches/comments with respect to python 2.1.1 and zope 2.4.3 and this issue? thanks, - joe n.

No, unfortunately, I haven't deleted any users.

Re: [Zope-dev] Iteration counter
> > I will need to use the $counter variable later on in the script.
Oh sorry, forgot that one...
Inside your loop, you can do:
But then again, this would only give the _total_ number of iterations that
have been made. If you only need this number :-), then please forget
everything that I wrote, and just use
sequence-length
or
_.len(WhatYouAreIteratingThrough)
Since you can't break out of a dtml-in, the number of iterations that will be
made will always be equal to the number of items ("length") in your sequence.

[Zope-dev] Iteration counter
I need a to create a simple counter variable that will store the number of
iterations by a structure. I have yet to find a way how to do
this in zope. Here is an example (in perl) of what I need to do:
@bar = ("sara","jane","kate");

$counter = $counter + 1;

I will need to use the $counter variable later on in the script. Does

Re: [Zope-dev] disabling gc does not necessarily hide memory corruption
Oh, ok, sorry for the misreport. It sounds then as if we need to fix whatever is causing the memory corruption that GC trips over. I dont know that we have a real good handle on what this is. Note that in the meantime, folks who turn off gc in order to work around the issue who are having leakage problems should probably consider the use of AutoLance, a product that will restart your Zope if memory consumption is too high: http://www.zope.org/Members/mcdonc/Products/AutoLance .

Yes, I understand that, but we use a lot of PythonScripts, mostly as ZClass methods, and a 1.5GB Data.fs full of ZClass instances. And ZCatalog, boy do we use ZCatalog.

It is no longer based on bytecodehacks, it uses Jeremy's compiler module.

Re: [Zope-dev] [IDEA] ZopeRoot and SiteRoot
Hi all. The Virtual Host Folder I released currently has a lot of the features you want, and is getting a number of other ones. I think it is worth a look, but then, that's just me. It replaces the VHM. I need to specify the interface, such as it is, but ... 1) The currently released one is very stable, as far as I can tell 2) I'm working on a CMF tool "front end" to it that should be released in beta within the week 3) I should also be releasing a new version this week that has all-but-the-kitchen-sink alias support per-virtual-host. Kind of a power-tools approach, where you are responsible for setting up exactly how you want the alias to work. Potentially confusing but hopefully flexible and powerful. And TTW, of course. 4) Once I have the CMF tool front end, I will of necessity have settled down on interfaces to get the various pieces of info you want (virtual host root, location from virtual root for breadcrumbs, etc.) It will need to be a bit specialized because of the alias bits. 5) I'm interested in getting feedback on it now (particularly the soon-to-be-released all-slicing all-dicing alias version) and adding features/cleaning it up as desired (starting January, when my life will hopefully have settled down a bit) For now, it and its current feature list is at http://www.zope.org/Members/poster/VHF I'll send a note on Announce when the new one is out.
