Removing nested go-routines in OfAgent message processing

When an OF message is received we call "parseHeader" in a goroutine,
thus there is no need to create new go-routines from within that method.
That is actually harmful as it messes up with the BarrierRequest handling,
avoiding nested routines guarantees that the Barrier Request are honored in ofagent

Ofagent-go

Ofagent-go provides an OpenFlow management interface for Voltha. It is a rewrite in Golang of the original ofagent that was written in python / twisted. The main driver behind the work was to introduce true concurrency to the agent for performance/scalability reasons.

Building

  1. Outside $GOPATH

    1. Read-only git clone https://github.com/opencord/ofagent-go.git
    2. To Contribute git clone https://gerrit.opencord.org/ofagent-go

  2. Compile go build -mod=vendor -o ./build/ofagent-go

Running

  • Normal Logging
    • ./build/ofagent-go -ofaddress=localhost openflowPort=6653 -volthaAddress=localhost -volthaPort=50057
  • Debug Logging
    • ./build/ofagent-go -debug -ofaddress=localhost openflowPort=6653 -volthaAddress=localhost -volthaPort=50057

Building with a Local Copy of voltha-protos or voltha-lib-go

If you want to build/test using a local copy or voltha-protos or voltha-lib-go this can be accomplished by using the environment variables LOCAL_PROTOS and LOCAL_LIB_GO. These environment variables should be set to the filesystem path where the local source is located, e.g.

LOCAL\_PROTOS=$HOME/src/voltha-protos
LOCAL\_LIB\_GO=$HOME/src/voltha-lib-go

When these environment variables are set the vendored versions of these packages will be removed from the vendor directory and replaced by coping the files from the specified locations to the vendor directory. NOTE: this means that the files in the vendor directory are no longer what is in the git repository and it will take manual git intervention to put the original files back.
