Juliusz Chroboczek e175ef0e49 Replace changed connections. 
We used to destroy and recreate connections, we now replace them atomically.
 2020-06-10 20:25:25 +02:00
Juliusz Chroboczek 448bb0374d Use pushConn to delete connections. 
The previous mechanism (going through up.local) was racy and complicated.

Juliusz Chroboczek 94c42ea784 Be more aggressive about growing the packet cache. 
Also add a test.

Juliusz Chroboczek f3b58bbf5c Don't complain about rate limiting. 2020-06-09 15:15:59 +02:00
Juliusz Chroboczek 4a526b4133 Implement packet pacing. 
We used to send all of the packets corresponding to a received packet
as a single burst, which led to persistent packet drops for clients
at the end of the queue.  Pace the writer, which introduces up to 1ms
extra jitter.
 2020-06-09 15:15:59 +02:00
Juliusz Chroboczek 2454e33df3 Use jiffies in rate estimator. 
This avoids locking in estimate.
 2020-06-09 14:14:32 +02:00
Juliusz Chroboczek f277b42e26 Check for connection state if not sending report packet. 
This avoids a situation when an RTCP sender never terminates.
 2020-06-09 13:46:04 +02:00
Juliusz Chroboczek f70ff2424e Detect sends on closed websocket explicitly. 
It turns out that send on a closed websocket doesn't throw, so handle
this case explicitly.  Thanks to Giuseppe Castagna for noticing.
 2020-06-09 01:49:55 +02:00
Juliusz Chroboczek 191624130a Use packet timestamps when saving to disk. 2020-06-09 01:06:09 +02:00

Juliusz Chroboczek da97560cb3 Protect upConn.tracks by the upConn mutex rather than the client mutex. 
Also don't rely on tracks being immutable in sendRR.
 2020-06-08 19:11:20 +02:00
Juliusz Chroboczek 8ba50bd2ca Tweak SR sending policy. 
Don't send SRs for tracks for which we have no time offset yet.
Send an unscheduled SR when we get our first time offset.
 2020-06-04 19:12:52 +02:00
Juliusz Chroboczek ce7f3670bc Resize packet cache dynamically. 2020-06-04 01:51:36 +02:00

This was broken when we pushed user notifications into addClient.

Juliusz Chroboczek b7a680671d Remove padding in packetcache. 
Since the packet entries are already overdimensioned, there's no
need to add additional padding.
