[AG-TECH] Trouble with VenueClient on AG2.1.2 (was : Certificate)

Wed Jun 2 22:19:05 CDT 2004

Hi

I'm still looking for a solution to my segmentation fault problem after 
while requesting a new certificate.

I've looked at the code of VenueClient.py and I've realised that it comes 
 from the line :
xext = crypto.X509Extension(name, critical, value)
in the 
/usr/lib/python2.3/site-packages/AccessGrid/CertificateRepository.py file 
(around line 604, as I've modified the file I can't say exactly which 
line).

After this line comes the segmentation fault. I've found too, with a grep 
X509Extension, that the only matches are in the binary files 
./python2.3/site-packages/OpenSSL_AG/SSL.so and 
./python2.3/site-packages/OpenSSL_AG/crypto.so. BTW, I have installed 
pyOpenSSL_AG0.5.1 from the AccessGrid download page of AGtk2.1.2 .

Origin of the call of X509Extension :

The xext = crypto.X509Extension(...) line is in fact a part of :
def CreateCertificateRequest(self, nameEntries, passphraseCB, keyType = 
KEYTYPE_RSA, bits = 1024, messageDigest = "md5", extensions = None).

This methode is in turn called by :
self.parent.createIdentityCertCB(str(self.name), str(self.email), 
str(self.domain),str(self.password),pinfo[0],pinfo[1],pinfo[2])
This line is in the CertificateRequestTool.py file and is part of def 
Validate(Self), around line 1000.

Once again, this instruction is called from :
page.Validate()
of def ChangingPage(self, event), around line 164 of 
CertificateRequestTool.py.

I hope all this stuff might help you to resolve my trouble. If there is no 
hope on your side (I mean on AG development team) please let me know too !

BTW, the VenueClient.log is the same as in the precedent mail (see below).

Thanks
	Joseph
