Hi,
I have an old patch on that code that instead checks if there are pending
data to send and exit the loop instead of a simple counter.
But I think that both solutions are not perfect. The reason is that a channel
is either reading or writing. If there's for instance a very big message to
Hi,
For now I simply used a counter to work around this issue.
while (... g_pollable_input_stream_is_readable ) {
if (loop > 10)
break;
}
Ugly but seems useful.

Hi,
yes, I think this is a real issue. I feel like I've stumbled across
something similar in the past when working on webdav.
So yeah, it seems like the channel might get blocked in one direction

However, that doesn't mean that other
Hi,
After debugging, I think my problem is probably not accociated with
cooperative multitasking.
Here is where spice-gtk read data:
/* treat all incoming data (block on message completion) */
while (!c->has_error &&
c->state != SPICE_CHANNEL_STATE_MIGRATING &&
Hi
About priority channel, here is my idea:
Priority control is added to data sending procedure.
Sending level(1 - 3) is initiated to 3, means all data can be sent. 2 means
data of level 1 and 2 channels can be sent, and level3 data will not be sent. 1
means only data of level 1 channel can

Thanks a lot, that information is very helpful, I will try that.

Hi,

remote data so the read won't stop other code. If you need to
Hi
Here is my experiment:
I created a new port-channel to transfer data between vdagent and spice-gtk. I
used a while loop to send 2kb data to gtk, gtk received and drop the data. In
the mean time I used a timer(1ms) to send 2kb data to vdagent.
Strange thing is that gtk will continually

Hi,
Spice-gtk is now using co-routine to handle different channel connections. When
a channel is handling data, other channels would have to wait, rather than
handling synchronously. That would bring us following issues:
1. If some less important channels (like usb channels) are transfering
