The FSF page says this in regards to the ZPL: [snip] > We urge you not to use the license of Zope for software you write. However, > there is no reason to avoid running programs that have been released under > this license, such as Zope. So what is the issue you are raising? Any software you write on or for Zope can be licensed in any manner you choose. Stallman et al may not "approve" of the ZPL mostly I think because it has more in common with the BSD license than the GPL, in that binary distribution of Zope is allowed without the source code.

Juan, thanks for shining some light towards this murky area. Maybe ZWiki and other zope products need to be LGPL or dual-licensed, maybe the zope license can use some refinement. I for one won't know without seeing some enlightened discussion of the issue. This stuff is unsexy but important. Best regards, -Simon

I'm new to this list, and i'm trying to port zope to os/2 to provide the os/2 community with such a fine program:) well, i installed the emx/gcc package and put python for os/2 1.5.2 up and running, and then picked up the zope src (2.2.2) from zope.org and did a: python wo_pcgi.py it then started to compile and exited with folowwing error: ------------------------------------------------------------------------ ------ Compiling python modules ------------------------------------------------------------------------ ------ Building extension modules ------------------------------------------------ Compiling extensions in lib/python cp /lib/python1.5/config/Makefile.pre.in . cp: /lib/python1.5/config/Makefile.pre.in: No such file or directory Traceback (innermost last): File "wo_pcgi.py", line 116, in ?

Simulate DTML-Method Proxy-Roles for python-product-methods ?
by Martin Grönemeyer 15 Nov '00

15 Nov '00

Hello. I've started to implement a small Product in Python. One method should be able to access an object in a folder which isn't accessible by anonymous but only by a special role. Is it possible to give a proxy-role to the python-method to access this object ? cheers Martin i.A.

ZopeBug: No Last-Modified for misc_/.../*.gif objects!!!!
by The Doctor What 15 Nov '00

15 Nov '00

I was looking at the cacheability of my website in zope, and saw that the misc_/OFSP/*.gif images (as in the icon objects) are NOT cacheable because they don't return *any* date info. If they *at least* returned a Last Modified, they'd be cacheable. I looked at the Zope Source and it looks like misc_.py just calls ImageFile objects. Why aren't the ImageFile objects setting these header info bits correctly? I'm not very knowledgable about Zope inside, but this seems like it should be happening. A side effect of fixing this problem would be that the manage screens would suddenly work much faster since the icons would not need to be reloaded EVERY time!! Here is the HEAD info from two ImageFile objects. The first is in the folder images which has a SiteAccess object that forces the Cache-Control object, a normal Image would not have the Cache-Control line. The second is a misc_.py object: checkhead http://docwhat.gerf.org:9673/images/thedoctorwhat HTTP/1.0 200 OK Server: Zope/Zope 2.2.2 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Wed, 15 Nov 2000 19:06:23 GMT Cache-Control: public, max-age=86400 Connection: close Content-Type: image/png Content-Length: 21717 Last-Modified: Wed, 15 Nov 2000 03:14:17 GMT checkhead http://docwhat.gerf.org:9673/misc_/OFSP/Folder_icon.gif HTTP/1.0 200 OK Server: Zope/Zope 2.2.2 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Wed, 15 Nov 2000 19:06:37 GMT Connection: close Content-Type: image/gif Content-Length: 903 I have attached by stupid checkhead program.

__replaceable__ or whatever it is ;-)
by Chris Withers 15 Nov '00

15 Nov '00

Hi, I was wondering how the stuff for attributes that are replaceable in instance and singleton attributesis getting on. Itamar says the code is in the CVS for Zope, but neither of us can find any documentation. Could whoever did the coding please put something in the Interfaces Wiki or point us to where the official documentation lives? Also, when is it going to land in a erleased Zoep version? 2.3 I guess... cheers, Chris

is _getCopy slow?
by seb bacon 15 Nov '00

15 Nov '00

My product is performing incredibly badly. I profiled it and got the following results: ncalls tottime percall cumtime percall filename:lineno(function) ...<snip>... 4/1 0.010 0.003 6.360 6.360 WebFactory.py:92(change_theme) 37/6 0.440 0.012 6.330 1.055 CopySupport.py:426(_getCopy) 37/6 0.710 0.019 6.270 1.045 ExportImport.py:126(importFile) 38 0.020 0.001 1.930 0.051 BaseStorage.py:200(tpc_finish) 38 1.910 0.050 1.910 0.050 FileStorage.py:768(_finish) For each folder in the instance, a method change_theme() is called recursively on each of its subfolders. The culprit appears to be the _getCopy call, which in turn calls importFile, and takes a whole second to call each time. The object being copied is in each case typically a folder containing 3 - 5 documents. Is _getCopy inherently slow, or am I misreading the profiler output, or is it more likely there's something wrong with my code? Cheers, seb

Automatic conversion to pdf format
by stefano.ciccarelli＠thewhitebird.com 15 Nov '00

15 Nov '00

<Newbie Alert> I am currently setting up a support website using Knowledge Kit. I would like to integrate it with ZpdfDocument, so that some documents could be automatically converted to pdf, without the need to cut and paste from Knowledge Kit to ZpdfDocument. Since I am a Zope newbie I did not find a way to make it work. I would really appreciate your help, Stefano Ciccarelli

large PersistentMapping
by Robin Becker 15 Nov '00

15 Nov '00

I'm trying to build a Reverse Cross Referencing Product. The idea is to enable documents to know which other documents in the Zope data base are pointing at them. I would like to use a persistent mapping to store the link information, but since eventually the object might be quite large will I get a performance hit when accessing only a small part of the object. It certainly seems to work for small instances, but I'm worried about what happens as my structure gets larger. Is there an alternate way to do this? The heart of the object are the methods def __init__(self, id, title): '''Initialise a new instance of RXRef''' self.id=str(id) self.title = str(title) self.title = title self._N = PersistentMapping() def addNode(self,n): '''Add a new node if not known''' N = self._N if not N.has_key(n): N[n]=[] def addLinks(self,src,DST): '''We have a single src and multiple destinations''' if type(DST) not in SEQTYPES: DST = [DST] N = self._N for dst in DST: self.addNode(dst) if src not in N[dst]: N[dst].append(src) def delLinks(self,src,DST): '''We have a single src and multiple destinations''' if type(DST) not in SEQTYPES: DST = [DST] N = self._N for dst in DST: if N.has_key(dst): if src in N[dst]: N[dst].remove(src) if N[dst]==[]: del N[dst] def getRLinks(self,dst): '''get links pointing to dst''' N = self._N return N.has_key(dst) and N[dst][:] or [] -- Robin Becker
