With the latest client changes the internal event loop requires a handle
to wait on. Add a new function to (re)set the newly added transport event handle.
Up to this commit the client and server state machine handling used
different return values for state machine changes.
This is fixed with this commit:
* Use common enum return values
* Use common helper functions
* Added transport_get_context to get rdpContext in IO callbacks.
* Added WINPR_ASSERT where possible.
* Fixed handle count mismatch in transport_get_event_handles
The async transport option is broken by design.
If used the main loop is called from the transport thread and the
main thread of the application.
Unless the transport layer is refactored to just work on queues
(input and output) this option will never work, therefore remove it.
This patch make it possible to limit the time that is passed when we call
XXX_check_fds functions. This should smooth the treatment between handling inputs
and handling incoming bitmap updates.
The default maximum time is set to 100 ms.
CMake 2.8 does not support default visibility on windows.
To allow building tests add the FREERDP_LOCAL define for each
function that is internal to FreeRDP.
When build with testing these functions are exported and available
for use by tests.
This big patch allows to have non-blocking writes. To achieve
this, it slightly changes the way transport is handled. The misc transport
layers are handled with OpenSSL BIOs. In the chain we insert a
bufferedBIO that will bufferize write calls that couldn't be honored.
For an access with Tls security the BIO chain would look like this:
FreeRdp Code ===> SSL bio ===> buffered BIO ===> socket BIO
The buffered BIO will store bytes that couldn't be send because of
blocking write calls.
This patch also rework TSG so that it would look like this in the
case of SSL security with TSG:
(TSG in)
> SSL BIO => buffered BIO ==> socket BIO
/
FreeRdp => SSL BIO => TSG BIO
\
> SSL BIO => buffered BIO ==> socket BIO
(TSG out)
So from the FreeRDP point of view sending something is only BIO_writing
on the frontBio (last BIO on the left).
