The H1 multiplexer is able to perform synchronous send. When a large body is transfer, if nothing is received and if no error or shutdown occurs, it is possible to not go down at the H1 connection level to do I/O for a long time. When this happens, we must still take care to refresh the H1 connection timeout. Otherwise it is possible to hit the connection timeout during the transfer while it should not expire. This bug exists because only h1_process() refresh the H1 connection timeout. To fix the bug, h1_snd_buf() must also refresh this timeout. To make things more readable, a dedicated function has been introduced and called to refresh the timeout. This bug exists on all HTX versions. But it is harder to hit it on 2.1 and below because when a H1 mux is initialized, we actively try to read data instead of subscribing for receiving. So there is at least one call to h1_process(). This patch should fix the issue #790. It must be backported as far as 2.0.
