I have no idea what the original symptom or situation was, so
I can't really comment. I'll note, however, that the error
refered to in Pascal's reply results from a wart in Python's
type-definition protocols that I thought I had fixed, but maybe
I proposed fixing it and didn't get around to it. :(
More specific would be helpful. Is a custom C type involved here?

Ok, in case anyone is interested, this nasty code change made it :
In Zope-2.8.4-final/lib/python/ZODB/serialize.py:
Change :

try:

I think Jim is the only one who could explain what you see. I can't
even find the place in the code which generates that error:
$ find . -name "*.py" -o -name "*.c" | xargs grep "is not safe"
./RestrictedPython/RCompile.py: The UNPACK_SEQUENCE opcode is not
safe because it extracts

Ok, just found it has already been reported several months ago, even with python 2.3.x:
http://www.zope.org/Collectors/Zope/1725
Does someone know of any kind of temporary workaround for this ?
Thanks !

Objet : [Zope] Zope 2.8.4+Latest cygwin installation
Hi,
I would like to know if anyone has been able to compile and run Zope
2.8.4 with Cygwin.
I just installed cygwin with latest stable packages.
I compiled python 2.4.2 (I know, not the supported version, so I am
about to try 2.3.5 now)
I had issues with the socket module, and from google I applied a
workaround that worked fine :
in Modules/socketmodule.c
Change :
#if defined(__sgi) && !defined(INET_ADDRSTRLEN)
#define INET_ADDRSTRLEN 16
#endif
To :
/*#if defined(__sgi) && !defined(INET_ADDRSTRLEN)*/
#define INET_ADDRSTRLEN 16
/*#endif*/
I made several python tests and all looks fine.
Then I compiled Zope 2.8.4 without any issue.
But when I run it, I get this error:
Site Error
An error was encountered while publishing this resource.
exceptions.TypeError
Sorry, a site error occurred.

Module ZODB.serialize, line 482, in getGhost
TypeError: Acquirer.__new__(Application) is not safe, use

Does anyone know what I can do ?
Thanks a lot.
