I have no problem on Linux using pcsc-lite 1.6.5 and your Python sample.
$ ./SCardCancel2.py Context established!
context canceled
Exception: Failed to release context: Command cancelled.
PCSC-Lite 1.5.3 is an old version. You should at least try with version 1.5.5.

Hi Ludovic,
I can not force ubuntu to update to 1.6.5., maybe you should tell them
to. Furthermore the example above gives no exception when running on
windows 7 or windows xp. (release context does return success instead of
cancel)

safesign (libaetpkss.so) hangs the process which uses
Below a program that shows the problem out of the context of SafeSign
(libaetpkss.so). The program runs fine on Windows (XP), and hangs on Ubuntu
with
PCSC-Lite 1.5.3
#! /usr/bin/env python
from smartcard.scard import *
try:
hresult, hcontext = SCardEstablishContext(SCARD_SCOPE_USER)
Also seen this problem with the 1.5 libs. However upgrading to 1.6.4
causes other issues: the hanging problem goes away but now the usb token
is never detected.
It could be a problem with libaetpkss.so since its closed source and we
can't tell if its correct or not.

I confirm that 1.6.x does not have this problem (I have installed it
from debian pool), so I have lost interest in patching an old version,
so I will be happy with a WONTFIX.
The answer to your questions:
- no, there is no one at the other end of the pipe
- I could generate a pcscd log, but I
Interesting patch. But I (as upstream maintainer) can't apply it before
I understand the problem.
If you can write a small sample to reproduce the problem without using a
proprietary software I will have a look.
If it is not possible I have some questions:
- does the FIFO the code is trying to
I don't know what the heck libaetpkss does, as it is closed source.
I assure you I am not happy to use proprietary code. It kept a lot of my
packages downgraded because this bug, and it took me a day to figure out at
last what is the problem.
It is possible that safesign calls linpcsc-lite in
The latest pcsc-lite 1.6.x do not use a fifo anymore. So the patch would
only be for the 1.5.x branch.
If I can't reproduce/understand the bug myself I will not apply the patch, even
if it works for you.
I note you have not replied to the 2 questions in my previous message.
