Re: Very strange problem with module ldapurl

[Jens V. <je...@zo...>]

i was stepping through the creation of l2 in the debugger, and to aid =20=

this i made the following change::

Index: ldapurl.py
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
RCS file: /cvsroot/python-ldap/python-ldap/Lib/ldapurl.py,v
retrieving revision 1.26
diff -r1.26 ldapurl.py
229c229
<     extensions=3DLDAPUrlExtensions({}),
---
 >     extensions=3DNone,
238c238
<     self.extensions=3Dextensions
---
 >     self.extensions=3Dextensions or LDAPUrlExtensions({})

i basically moved the creation of that LDAPUrlExtensions object from =20
the argument list into the function itself. that solved the problem for =20=

me it seems. here is my output now::

l1 before creation of l2:
ldap://host1/????X-=20
BINDPW=3Dpasswd1,dummyext1=3Ddummyvalue1,bindname=3Dcn=3DUser1
l1 after creation of l2:
ldap://host1/????X-=20
BINDPW=3Dpasswd1,dummyext1=3Ddummyvalue1,bindname=3Dcn=3DUser1
l2 itself:
ldap://host2/????X-=20
BINDPW=3Dpasswd2,dummyext2=3Ddummyvalue2,bindname=3Dcn=3DUser2

hmmm.... :)
