Audio's callerId depends on the user name and there isn't
an "on-demand" way of fetching that field internally, making callerId
assembly with trusted attributes (server-side generated) impossible in
bbb-webrtc-sfu.
The new extra header (User-Name, mapped to user_name in the proxied
connection) allows fetching the user name field in a cheap way and
consequently provides a cheap+safe way of assembling the callerId.
Alternatives I've considered but discarded:
- a new akka-apps req-resp pair for fetching the user name (+overhead)
- a new akka-apps req-resp pair for generating the callerId (+overhead)
- piggybacking on GetMicrophonePermissionReq/Resp to generate the
callerId (same overhead, but mixing responsabilities)
yq package is now provided in the BigBlueButton support PPA for BBB 2.5,
so we can depend on the package now. Ensure the dependency is specific
to avoid an incompatible yq version 4 from being installed.
The old 6h values seem far too large and I cant recall nor find any good
justification for them to be that way
Reducing the timeouts to more sane values allow resources (WebSockets) to be
cleaned up faster
The heartbeat routine in bbb-webrtc-sfu runs every 20s. The heartbeat
routine in SIP.js/FS runs every 30(+10)s. The new timeouts are those values
multiplied by 3.
Remaining, to be handles separately:
bbb-html5 before-remove and after-install -- sip.nginx needs to be
handled in bbb-conf
bbb-freeswitch-core -- /tmp/vars xml, etc. -- not sure how to handle
beta.6 updates mediasoup 3.9.0 which has a new Meson build system
That new build system does a pretty good job cleaning compiler leftovers on its
own, so theoretically our cleanup code isn't needed anymore.
Amend history:
build/packages-template/bbb-webrtc-sfu/build.sh -> v2.6.0-beta.6 to beta.7
... drop build artifacts from compiling mediasoup. This reduces package
size from ~ 54 MB to ~ 12 MB.
Additionally this drops the `npm rebuild` command from the after-install
script. It should not be necessary to recompile stuff during
installation. To ensure a clean `node_modules` directory, it will be
cleaned in the before-install script.
