[issue34440] Certificate verify failed (works fine in 3.6)

2018-08-20 Thread Lennart Grahl 


New submission from Lennart Grahl :

When running the attached script with the attached cert, Python 3.7 raises an 
exception (see https://paste.pound-python.org/show/VLr84Yn2Fnz6RSKEq3ui/). In 
Python 3.6, the certificate is being accepted.

I don't see anything wrong with the self-signed certificate.

You can (hopefully) reproduce this by running minimal_server.py

Hi.

I don't see why the certificate would not be valid for that address. Python 3.6 
also accepts it without any modifications to the script.

[issue27124] binascii.a2b_hex raises binascii.Error, not TypeError

2016-05-25 Thread Lennart Grahl 

New submission from Lennart Grahl:

When using binascii.a2b_hex (or binascii.unhexlify) and the argument is 
invalid, the doc states that it should raise a TypeError for invalid arguments 
(e.g. passing an odd-length string).

However, it does raise binascii.Error instead of TypeError:

try:
binascii.a2b_hex('a')
except Exception as exc:
print(type(exc))

[issue27124] binascii.a2b_hex raises binascii.Error and ValueError, not TypeError

What surprised me even more was that it raises ValueError (although 
binascii.Error inherits ValueError) in case a unicode string has been passed as 
an argument:

try:
binascii.a2b_hex('รค')
except binascii.Error:
print('binascii.Error')
except ValueError:
print('ValueError')
