This document provides instructions for developers to setup their environment and work on the upcoming BBB 2.0 (tentative release version).
Follow the (install instructions)[http://docs.bigbluebutton.org/install/install.html] for 1.1.
Make sure you have a working BBB 1.1 before you proceed with the instructions below.
Setup your development environment following these (instructions)[http://docs.bigbluebutton.org/dev/setup.html]
Checkout the development branch move-java-classes-from-bbb-web-to-bbb-common-web from this (repository)[https://github.com/ritzalam/bigbluebutton]
Open nine (9) terminal windows so you will dedicate one window for each bbb-component. You can name them client, bbb-apps, apps-common, red5, akka-apps, akka-fsesl, bbb-web, common-web, and messages.
On you bbb-client terminal, run the following commands.
cd ~/dev/bigbluebutton/bigbluebutton-client
Build build a specific locale (en_US default)
ant locale -DLOCALE=en_US
To build all locales
ant locales
This will take about 10 minutes (depending on the speed of your computer). Next, let's build the client
ant
This will create a build of the BigBlueButton client in the /home/firstuser/dev/bigbluebutton/bigbluebutton-client/client directory.
On your red5 terminal, turn off red5 service
sudo systemctl stop red5
You need to make red5/webapps writeable. Otherwise, you will get a permission error when you try to deploy into Red5.
sudo chmod -R 777 /usr/share/red5/webapps
On your message terminal, run the following commands. Other components depends on this, so build this first.
cd ~/dev/bigbluebutton/bbb-common-message/
sbt clean
sbt publish
sbt publishLocal
We've split bbb-apps into bbb-apps-common and bigbluebutton-apps. We need to build bbb-apps-common first.
On your apps-common terminal, build the bbb-apps-common component.
cd ~/dev/bigbluebutton/bbb-apps-common/
# Force updating of bbb-commons-message
sbt clean
# Build and share library
sbt publish publishLocal
On your bbb-apps terminal, run the following commands.
cd ~/dev/bigbluebutton/bigbluebutton-apps/
# To make sure the lib folder is clean of old dependencies especially if you've used this
# dev environment for BBB 1.1, delete the contents of the lib directory. You can only to
# do once.
rm lib/*
# Force updating dependencies (bbb-apps-common)
gradle clean
gradle resolveDeps
gradle war deploy
On your red5 terminal, start red5.
cd /usr/share/red5
sudo -u red5 ./red5.sh
On your akka-apps terminal, start akka-apps
cd ~/dev/bigbluebutton/akka-bbb-apps
# To make sure the lib folder is clean of old dependencies especially if you've used this
# dev environment for BBB 1.1, delete the contents of the lib directory. You can only to
# do once.
rm lib_managed/*
# We need to stop the existing packaged akka-apps
sudo systemctl stop bbb-apps-akka
# Now we can run our own
sbt clean
sbt run
On your akka-fsesl terminal, start akka-fsesl
cd ~/dev/bigbluebutton/akka-bbb-fsesl
# To make sure the lib folder is clean of old dependencies especially if you've used this
# dev environment for BBB 1.1, delete the contents of the lib directory. You can only to
# do once.
rm lib_managed/*
# We need to stop the existing packaged akka-fsesl
sudo systemctl stop bbb-fsesl-akka
# Now we can run our own
sbt clean
sbt run
We've split up bbb-web into bbb-common-web and bigbluebutton-web. We need to build bbb-common-web first.
On your common-web terminal, run these commands
cd ~/dev/bigbluebutton/bbb-common-web/
# To make sure the lib folder is clean of old dependencies especially if you've used this
# dev environment for BBB 1.1, delete the contents of the lib directory. You can only to
# do once.
rm lib_managed/*
# Force updating of dependencies especially bbb-commons-message
sbt clean
sbt publish publishLocal
First we need to remove the old bbb-web app from tomcat to avoid duplicate messages
sudo cp /var/lib/tomcat7/webapps/bigbluebutton.war /var/lib/tomcat7/webapps/bigbluebutton.war-packaged
sudo rm -r /var/lib/tomcat7/webapps/bigbluebutton
On your bbb-web terminal, start bbb-web
cd ~/dev/bigbluebutton/bigbluebutton-web
Get the salt and BBB URL from /var/lib/tomcat7/webapps/demo/bbb_api_conf.jsp
Edit grails-app/conf/bigbluebutton.properties and change the following with
the salt and IP you got from above.
bigbluebutton.web.serverURL=http://192.168.74.128
securitySalt=856d5e0197b1aa0cf79897841142a5f6
Start bbb-web
# To make sure the lib folder is clean of old dependencies especially if you've used this
# dev environment for BBB 1.1, delete the contents of the lib directory. You can only to
# do once.
rm lib/*
gradle clean
gradle resolveDeps
grails clean
sudo chmod -R ugo+rwx /var/log/bigbluebutton
grails -Dserver.port=8888 run-war
If things started without errors, congrats!
In bigbluebutton-apps, from InMessages.scala choose the message to convert.
case class UserShareWebcam(meetingID: String, userId: String, stream: String) extends InMessage
In bbb-apps-common, add new message in BbbCoreEnvelope.scala
object UserShareWebcamMsg { val NAME = "UserShareWebcamMsg" }
case class UserShareWebcamMsg(header: BbbClientMsgHeader, body: UserShareWebcamMsgBody)
Define UserShareWebcamMsgBody in MessageBody.scala
case class UserShareWebcamMsgBody(userId: String, stream: String)
From the client, send message as
{
"header": {
"name": "UserShareWebcamMsg",
"meetingId": "foo-meetingId",
"userId": "bar-userId"
},
"body": {
"streamId": "my-webcam-stream"
}
}
In ReceivedJsonMsgHandlerActor, deserialize the message with implementation in ReceivedJsonMsgDeserializer.
case UserShareWebcamMsg.NAME =>
for {
m <- routeUserShareWebcamMsg(jsonNode)
} yield {
send(envelope, m)
}
Route the message in ReceivedMessageRouter.
def send(envelope: BbbCoreEnvelope, msg: UserShareWebcamMsg): Unit = {
val event = BbbMsgEvent(msg.header.meetingId, BbbCommonEnvCoreMsg(envelope, msg))
publish(event)
}
Handle the message in MeestingActor replacing the old implementation.
A complete example would be the ValidateAuthTokenReqMsg.
