9dd1555c81 GUACAMOLE-249: Do not include CB_RESPONSE_OK flag in Format List PDU. 
The CLIPRDR specification requires that the msgFlags field for the
Format List PDU be set to 0x0000. The function within FreeRDP overrides
this value to 0x0000, but it is still incorrect to attempt to set it.

16be3af03c GUACAMOLE-249: Load FreeRDP plugins regardless of entry point interface. 
Most plugins built into FreeRDP implement the PVIRTUALCHANNELENTRYEX
entry point, but the FreeRDP standard function for loading plugins only
supports PVIRTUALCHANNELENTRY. It appears that only the commandline
argument parser included with FreeRDP was updated to leverage the new
entry points.

GUACAMOLE-859: Merge correct Caps Lock keysym sent via RDP 2019-08-13 21:11:46 -04:00
Weston Thayer
a189c9ab8a GUACAMOLE-859: Remove +ext from Caps Lock keymapping. 
When connected with a Guacamole RDP session, the keysym for Caps Lock (0xffe5) is sent over RDP as scancode 0xe03a. Windows does not understand this scancode, thus does not generate the correct VK (Virtual Key) events. Removing +ext from the keymap sends the scancode 0x003a, which is correctly recognized by Windows as Caps Lock. This enables Windows applications to listen for key down and key up events on the Caps Lock key while connected via a Guacamole RDP session.

Note: this issue likely went un-noticed for a long time because it only impacts the key up and down events for the Caps Lock key, not Caps Lock's effect on sending uppercase [A-Z] characters.

cc4671d7a1 GUACAMOLE-662: Correct handling of buffering within nested socket. 
The nested socket implementation seems to have never been properly
updated since guac_socket was changed to rely on implementation-specific
buffering. This meant that absolutely every write resulted in a nest
instruction being sent to the parent socket.

Data should instead be built up within the internal buffer, with each
flush writing as much of the internal buffer as possible within a nest
instruction, leaving any partial UTF-8 characters at the end of the
buffer for later completion with future writes.
