This is not all of it as it is not possible (or at least I do not know
of a way) to get all suggestions for a repo/project. Did this via loop
searching mainly and taking the modernize suggestions.
* Rework node stats a bit.
Related protocol PR - https://github.com/livekit/protocol/pull/1023
- Make a config for node stats measurements. Wanted to put the config in
`routing` package, but a circular dependency forced me to put in
config.go
- Make rate calculations explicit, i. e. requested via config.
Previously, it had some odd checks to decide when to calculate rate
and it would have been calculating over different windows.
- Report signal/data channel bytes every 5 seconds to stats collection
module. Previously, it was doing it every 30 seconds and that meant
some windows could have had a large spike
NOTE: Still need to think about this for load calculations as a large
number of participants leaving could flush in a small window and that
could report a large spike in bytes/packets. Maybe need to ignore
signal bytes for load calculation?
* deps
* use default node stats config if given config is nil
* split out node stats into a struct for re-use
* update config
* Integrate logger components
Dividing into the following components
* pub - publisher
* pub.sfu
* sub - subscriber
* transport
* transport.pion
* transport.cc
* api
* webhook
* update go modules
* Use net.JoinHostPort to build "host:port" strings for `net.Listen`
net.JoinHostPort provides a unified way of building strings of the form
"Host:Port", abstracting the particular syntax requirements of some
methods in the `net` package (namely, that IPv4 addresses can be given
as-is to `net.Listen`, but IPv6 addresses must be given enclosed in
square brackets).
This change makes sense because an address such as `[::1]` is *not* a
valid IPv6 address; the square brackets are just a detail particular to
the Go `net` library. As such, this syntax shouldn't be exposed to the
user, and configuration should just accept valid IPv6 addresses and
convert them as needed for usage within the code.
* Use '--bind' CLI flag to also filter RTC bind address
The local address passed to a command such as
livekit-server --dev --bind 127.0.0.1
was being used as binding address for the TCP WebSocket port, but was
being ignored for RTC connections.
With `--dev`, the conf.RTC.UDPPort config is set to 7882, which enables
"UDP muxing" mechanism. Without interface or address filtering, Pion
would try to bind to port 7882 on *all* interfaces.
This was failing on a system with IPv6 enabled, when trying to bind to
an IPv6 address of the `docker0` interface. It seems to make sense that
the user-passed bind addresses are also honored for the RTC port
bindings.
* let panics crash
* Revert "let panics crash"
This reverts commit 8027cccadd.
* catch and log panics then os.Exit
* Recover only recovers, caller can exit
* only exit on pacic, still need Recover calls in goroutines
tidied up list-nodes command output:
made the table narrower (to fit on the screen);
made numbers humanized;
added nodes state (useful with SHUTTING_DOWN state);
added retransmitted packets per second.
* cli: Allow setting the current node region with flag or env variable
Also add region to "starting LiveKit server" log.
* routing: Add region to node registration
Register the node's region on the selected router so it can be used for
region aware node selection.
Also add the region to the list-nodes output.
* regionaware: Set minDist to zero for the current node
If you don't set the minDist when leaving the loop early for a node that
matches the current region, the minDist value with still be at max. This
causes the the wrong node to be selected if the current node is the
first one the loop passes through.
Add a test that validates this change. The new test fails if this new
change is not in place.
* prestop and hasparticipants in interface
* add prestop function to existing routers
* fakerouter prestop
* update protocol version
* read lock
* redis router graceful stop
* test fix
* force stop
