Суть 0000149: TransferCompleted signal is emitted even the connection is rejected.
Подробности When a OBEX client connects to a server with the auto_accept as false, the server user is prompted asking whether to accept the incoming connection or not. If the user rejects the conneciton, the OBEX session is removed successfully. But the TransferCompleted signal is sent to the client and the client misbehaves in my casse :)

So I think TransferCompleted signal should not be emitted if the server user have rejected the connection, i.e., ODS needs to check the acceptance condition at the OBEX_CMD_PUT case.

 I am not so sure that this is a good idea. Basically the transfer ends either with ErrorOccurred or TransferCompleted signals. You are proposing to introduce one more case where none of these signals would be emitted upon transfer completion. Unless you can convince me to do this, I would recommend changing your code.

 Hi,
I add more remarks and logs about the situation in more tail.
If the OBEX server user rejects the incoming client OPP file transfer request, ODS sends series of signals as the dbus-monitor logs below. ODS sends TransferCompleted signal after series of TransferStarted and TransferProgress signals as a normal transfer success case, even though the server has rejected the request. The server application would understand that the TransferCompleted signal does not mean the transfer success cause the application has rejected it. But the TransferCompleted signal itself does not say anything about the result of the client request.

That's why I think ODS should not send TransferCompleted signal in this case rather shoud send ErrorOccurred in this case.

By the way, I verified that the bug: 0000148 has been fixed.

 Which ods version or svn revision are you using here?

 I'm using ODS release 0.4.2 with openobex 1.4.

 I did some work on this after 0.4.2, so get newest ods from svn.

 I tested with the newest ODS version in SVN.
There has been lots of changes during this short period of time :)
Seeing the logs below from dbus-monitor tool, Cancelled singnal is emitted before the TransferCompleted singal followed by Disconnected signal. I think ErrorOccurred signal or no signal is better in this initial cancelling case because actual transfer has rejused by the server. But if this stream of signal flow breaks current ODS signaling mechanism I would change my application code using previous information.
