Jimmy updated GUACAMOLE-1354:
-----------------------------
Description:
I found the printing problem that freezes the guacd when printing quickly and
successively.
*[Test environment]*
RDP Server: Windows Server 2019 Datacenter
Server: Ubuntu 18.04
Guacamole Client:
[#6644955f|https://github.com/apache/guacamole-client/commit/6644955fff07db7844f0b495b4abfabf2b700e21]
on master branch
Guacamole Server:
[#44145f68|https://github.com/apache/guacamole-server/commit/44145f681aa3cf08e9cf01e99a68096c77bcab39]
on master branch
Chrome: 90.0.4430.212
User: Windows 10 Pro, 20H2
*[Test case]*
# Connect to Windows Server 2019 through Apache guacamole.
# Open Notepad.
# Type some text.
# Press Ctrl+P and select Guacamole Printer.
# Click "Print" button.

When repeating step 4 and 5 quickly and successively, we can see this issue
soon.
I attach the guacamole server log when encountering the freeze issue.
*[Rough Analysis]*
When the guacd doesn't receive *GUAC_RDP_PRINT_JOB_ACK_RECEIVED* from the
guacamole client due to unknown reason, *guac_rdp_print_job_wait_for_ack()*
function suspends execution of the *guac_rdp_print_job_output_thread()* thread
for ever.
Thanks.
