hi! i've posted this problem on the zope-list a couple of days ago with no reply so i'm trying zope-dev now: i'm using this code to output A B C ... Z:    this works fine in my Zope-1.10.2/Linux installation but Zope-1.10.2/Win95 generates this error message: Error type: InError Error value: Strings are not allowed as input to the in tag. can someone explain this inconsistency? why are strings allowed on linux but not on win95? thilo

zope-dev: ? fully render dtml in an external method ?
by Dr. Ross Lazarus 30 May '99

30 May '99

In an external method, is there a simple way to get a fully rendered html representation of a zope dtml method/document ? eg, I can loop through all the things I want using types = ('DTML Document','DTML Method') # meta types to snarf for t in types: for fooname,foo in self.objectItems([t]): With dtml method foo, I can call str(foo) and get an html quoted version complete with zope tags...not quite what I had in mind. I've tried HTML(foo) from DT_HTML without success...is there some simple way to do this !?

RE: [Zope-dev] The Zope CGI executable, rewriting URLs on IIS

Local named pipes are much faster than TCP sockets on NT because connections are not routed through the networking layer, but are directly by the kernel. On NT LANs, named pipes is the most efficient IPC mechanism; if you go over a slow link (eg., WAN) you're right -- TCP definitely rules. As for your #2, give me a clue as to why you'd want to run Zope on a Win9x box. When did Win9x become a server OS? Never mind the fact that the wrapper service that comes with Zope will not run on Win9x, and the executable CGI wrapper won't work without it. I'm almost done with the ISAPI port now. It is based on Brian Lloyd's code, which uses named pipes. -- Alexander Staubo http://www.mop.no/~alex/ "It has taken the planet Earth 4.5 billion years to discover it is 4.5 billion years old." --George Wald >-----Original Message----- >From: zope-dev-admin(a)zope.org [mailto:zope-dev-admin@zope.org]On Behalf >Of Brad Clements >Sent: 28. mai 1999 22:50 >To: zope-dev(a)zope.org >Subject: Re: [Zope-dev] The Zope CGI executable, rewriting URLs on IIS > > >On 27 May 99, at 9:30, Jeff Bauer wrote: > >> A caveat: PCGI on win32 is experimental and uses TCP/IP >> sockets (Unix version uses AF_UNIX IPC).

ext. method writing to file solved...

Ah. Stupid me. All I really had to do was chmod the directory properly.

zope/apache - external product writing to a file system ?
by Dr. Ross Lazarus 29 May '99

29 May '99

We're running zope 1.10.2 under apache. Briefly, my question is - What's the easiest way to convince apache/zope to allow an external method to actually write some files somewhere - do I only need to ask my friendly (!) sysadmin to adjust some apache permissions or is there more to this ? Details - In order to get a static html representation of a zope folder and subfolder objects, I thought I'd write myself an external method which walks the folder structure and tries to write the dtml stuff to the file system as a static mirror of the dynamic zope site. Problem. Everything seems to work fine except that all of the file writes fail - IOError 13 - permission denied. I thought I'd be sneaky and tried using the zope/var directory assuming that apache was stopping zope from writing to any arbitrary directory. No joy - zope too smart to allow me to do that. I'll release it as a contributed product if I can get this sorted out. (Yes, wget already does this but we've had some interesting problems...) -- Dr Ross Lazarus Associate Professor and Sub-Dean for Information Technology Faculty of Medicine, A27, R126a, University of Sydney, Camperdown, NSW 2006, Australia Tel: (+61 2) 93514429 Mobile: +61414872482 Fax: (+61 2) 93516646 Email: rossl(a)med.usyd.edu.au http://www.health.usyd.edu.au/people/rossl.htm

Detecting object deletions
by Robert Leftwich 28 May '99

28 May '99

How do I detect if an object is being deleted ? I need to detect when an object is being deleted in order to perform some clean up. The deal is (excuse the highly imaginative names) : Foo inherits from Bar which inherits from Folder Foo has a __del__ method which prints 'Foo is being deleted' When an instance of Foo is deleted (via manage_delObjects) I would expect __del__ to be called at some point but nothing happens. Am I overlooking something obvious ? Thanks Robert Leftwich (running Zope 1.10.2 on win32 NT) PS This is becoming quite urgent, so if you can help, please do so !

I assume it > communicates with the Zope service, but how? Using HTTP? Basically, the windows service/cgi.exe stuff is a holdover from the past, when PCGI didn't work on windows. The win32 service listens on a named pipe for connections from the cgi executable - the two communicate using the PCGI protocol. If you'd like, I can probably send you the service/cgi code - I'm sure that the powers that be here would love to see an ISAPI version of the cgi executable. Over time, I expect PCGI to obsolete this system, but there just haven't been enough resources to work on this lately :( While I'm pretty sure PCGI actually works now on win32, there is some work to do rolling it into the installation, documentation, etc. > > The reason I ask is that I'd like to emulate the behaviour in an ISAPI > filter DLL.

I tried writing a (rather simple) filter once, but never really tried to tackle this problem. I assume that if you had an ISAPI thing calling the service though, it could probably munge the request a bit to do the right thing.

Bug in Client.py?
by jhauser＠ifm.uni-kiel.de 28 May '99

28 May '99

Tried to gather data remotely with a ZClient. There is the possibility to give type arguments to the name/keyword pairs. This does not function from the commandline, right? I get a string in every case. Example: python Client.py http://localhost:9222/test/rinfo 'data=[1,2,3]' The real bug is with the file specifier. There is only an open in line 625, this should be an v=open(v).read() or do I miss something? __Janko
