BUG/MEDIUM: stconn: Unblock SC from stream if there is enough room to progrees
At the end of process_stream(), in sc_update_rx(), the SC is now unblocked
if it was waiting for room and the free space in the input buffer is large
enough. This patch should fix an issue with the compression filter that can
leave the channel's buffer empty while the endpoint is waiting for room to
progress. Indeed, in this case, because the buffer is empty, there is no
send attempt and no other way to unblock the SE.
This commit depends on following commits:
* MEDIUM: tree-wide: Change sc API to specify required free space to progress
* MINOR: stconn: Add a field to specify the room needed by the SC to progress
* MINOR: peers: Use the applet API to send message
* MINOR: stats: Use the applet API to write data
* MINOR: cli: Use applet API to write output message
It should fix a regression introduced with the commit 341a5783b
("BUG/MEDIUM: stconn: stop to enable/disable reads from streams via
si_update_rx").
It must be backported iff the commit above is also backported. It was not
backported yet and it is thus probably a good idea to not do so to avoid to
backport too many change..
