[Pcsclite-muscle] Bug in reconnecting to a card.

[Abraham Macias Paredes]

Hi again, 

 After some tests I think that a second ?Connect? invalidates the transactions (Python test attached).

 

Or maybe there are a couple of seconds of timeout before invalidating the transactions and allowing the connection (because when you run the test you can notice a couple of seconds of delay before the second ?connect?).

 

The output of the test in my Windows 10 is:

 

c:\Python27>python.exe test.py

Context established!

PCSC Readers: ['Dell Smart Card Reader Keyboard 0']

Using reader: Dell Smart Card Reader Keyboard 0

Connected with active protocol 1

Start transaction

Connect again

Connected with active protocol 1

Start transaction (card 2)

End transaction (card 2)

End transaction in the first connection

Exception: failed to end a transaction: Se ha reiniciado la tarjeta inteligente, por lo que no es v?lida ninguna informaci?n de estado compartido.

Released context.

press Enter to continue

 

Best regards!

Hi,

*         Do you get the same behavior on Windows?
No, in Windows seems that ?disconnect? and ?reconnect? ends all started transactions.

*         What should be the correct behavior of pcsc-lite?
I think that is logical to think that when you ?reconnect? or ?disconnect? a card, all estarted transactions are ended.

Thank you and best regards!

Hi PCSC lite Project people,

 

Hello,
 

  I?m developing a software that nowadays is not stable (my software is buggy), but I detected that a bug in my software causes a bug in pcsc-lite.

 

The ?SCardReconnect? doesn?t check if the connection has a transaction opened. So if you open a transtaction and reconnects the transaction is still opened. And also you can open a new transaction. 

 

Interesting.

Do you get the same behavior on Windows?

What should be the correct behavior of pcsc-lite?

Bye
