[issue22365] SSLContext.load_verify_locations(cadata) does not accept CRLs

2014-09-09 Thread Ralph Broenink 

Ralph Broenink added the comment:

Here's a minimal example of the issue, assuming you have obtained a CRL in PEM 
format, e.g. from https://www.emulab.net/genicrl.bundle:


import ssl
context = ssl.create_default_context()

path = 'path/to/crl.crl'

# Working:
context.load_verify_locations(cafile=path)

# Not working:
with open(path, 'r') as f:
context.load_verify_locations(cadata=f.read())


Replacing the path to the CRL with a path to a CA works in both cases.

[issue22365] SSLContext.load_verify_locations(cadata) does not accept CRLs

2014-09-08 Thread Ralph Broenink 

New submission from Ralph Broenink:

Issue #18138 added support for the cadata argument in 
SSLContext.load_verify_locations. However, this argument does not support 
certificate revocation lists (CRLs) to be added (at least not in PEM format):

ssl.SSLError: [PEM: NO_START_LINE] no start line (_ssl.c:2633)

The documentation of this method is rather vague on this subject and does not 
state explicitly this is not allowed:

This method can also load certification revocation lists (CRLs) in PEM or 
or DER format. In order to make use of CRLs, SSLContext.verify_flags must be 
configured properly.

I think CRLs should be allowed to be loaded using the cadata argument. However, 
the documentation could use some polishing too: At least one of cafile or 
capath must be specified. is outdated since the introduction of cadata.

[issue22154] ZipFile.open context manager support

2014-08-06 Thread Ralph Broenink 

New submission from Ralph Broenink:

In Python 3.2, context manager support for ZipFile was added. However, I would 
also love the ability for ``ZipFile.open`` to be used as a context manager, 
e.g.:

from zipfile import ZipFile
with ZipFile(test.zip, r) as z:
with z.open(test.txt, r) as f:
print(f.read())

Perhaps this should be documented then :)
