Hello. Do any of you know of an IDE(preferably open source) that I can use to develop/debug/test python code in? Thanks. - Asad

Creating a Zope Product
by Asad Habib 12 Dec '03

Does anyone know how to create a Zope Product? One example would be the Local File System Object that I am using. If you could point me to some resources that would be great. Thanks. - Asad

Changing the Appearance of the Contents of a Local File System Object
by Asad Habib 12 Dec '03

12 Dec '03

Hello. I have a folder that I have created at the root level and inside this folder I have placed one Local File System object. The Local File System object contains two File objects. When I view the Local File System object by clicking on the 'View' option provided by the management interface, I can see that it contains two File objects. What I would like to do is to change the way that these File objects are displayed. Specifically, I would like to show only certain attributes that these File objects have and hide others. Right now, the following attributes are shown: type, icon, size, and last modified time(mtime). I would like to hide the size and last modified time(mtime) attributes. I want these attributes to be set but I do not want their values to show. FYI, I am using the Local File System Product. Any help would be greatly appreciated. Thanks. - Asad

Post-mortem [Was: Zope 2.7.0 b3 regressions]
by Stefan H. Holek 12 Dec '03

12 Dec '03

After causing all this noise, let me summarize what I now understand is the intended behavior of Zope's URL methods. Given an object is accessed by /VirtualHostBase/http/example.com:80/VirtualHostRoot/_vh_foo/folder/doc 1) doc.absolute_url() Returns the full URL of doc including protocol and host. e.g. http://example.com/foo/folder/doc 2) doc.absolute_url(relative=1) Returns the path of doc, relative to the virtual root. e.g. folder/doc 3) REQUEST.BASEPATH1 + '/' + doc.absolute_url(1) Results in the absolute path of doc, starting at the server root. e.g. /foo/folder/doc Comments: ad 2) This may or may not be RFC-2396 compliant, I must admit I fail to parse the RFC here. It certainly appears necessary for b/w compatibility at least. ad 3) It may still be a good idea to add an API method for this (e.g. 'absolute_path') like I proposed in February (#809). If only to increase the visibility of this requirement. I understand that it may be too late for 2.7. Whoever is going to unroll the fix, please also adapt the tests in Products/SiteAccess/tests. Finally, please accept my apologies for the tone of some replies; I do certainly need a vacation.

ZServer HTTP 1.1 support
by Paul Winkler 11 Dec '03

11 Dec '03

I noticed this in ZServer/README.txt (zope 2.6.2): HTTP 1.1 support is ZServer is incomplete, though it should work for most HTTP 1.1 clients. Anybody know what specifically is "incomplete"? In particular, some people on my team asked me if zserver supports "persistent" connections, and I didn't know how to answer. I'm looking now at HTTPServer.py and the docstrings suggest that it does ... yes? no? -- Paul Winkler http://www.slinkp.com Look! Up in the sky! It's RADIO FOOLISH POLYETHYLENE TEREPHTHALATE SQUID!

2.7 on Windows
by Lennart Regebro 11 Dec '03

11 Dec '03

I'm having serious trouble in getting HEAD running in Windows. Obviously, configure doesn't work. :-) I found something on zope.org telling me to run python inst\configure.py and in in turn tells me to run nmake build. This builds Zope, but creates no z2.py or runzope.py or anything like that. What next? Any ideas?

Preview of a Stackless Zope Application
by Christian Tismer 11 Dec '03

11 Dec '03

Howdy, I made a little demo of Stackless Zope. It is just a quick hack to see how things can work. The example is a long-running Python method which "prints" lines to the browser. The key to this surprizing solution is tasklets, channels, and thread pickling.

Heads up: about to merge new-style ExtensionClass and ZODB 3.3 into Zope 2 head
by Jim Fulton 10 Dec '03

10 Dec '03

Hi, I'm just about to start writing the checkin logs for the merge of new-style ExtensionClass and ZODB 3.3 into the Zope 3 head. I expect the merge to be done within the next hour or two. Except for a test failure and some warnings pre-existing on the head, all of the tests and Zope runs. This is a huge change though and I expect this to be the beginning of a period of relative instability. Hoepfully, we can all work together to quickly address whatever problems come up. As I mentioned in another message, old Zope 2 databases won't work on the head for a while until I have a chance to come up with a mechanism for converting ancient BTrees and intSets. Unfortunately, until a change I checked into the Zope 2.7 branch on Wednesday, Zope was continuing to use the old depricated BTrees for a key data structure.
