paxos-call-chain.dot describes to some detail the call chain involved in the
|
||
|
|
Paxos algorithm, paying special consideration to the messages involved.
|
||
|
|
|
||
|
|
This information is not easily obtainable by Doxygen, as it does not follow
|
||
|
|
the call chain when messages are involved, since it becomes an async workflow.
|
||
|
|
|
||
|
|
To obtain the graph one should run
|
||
|
|
|
||
|
|
dot -T<format> paxos-call-chain.dot -o paxos-call-chain.<format>
|
||
|
|
|
||
|
|
e.g.,
|
||
|
|
|
||
|
|
dot -Tps paxos-call-chain.dot -o paxos-call-chain.ps
|
||
|
|
|
||
|
|
or
|
||
|
|
|
||
|
|
dot -Tpng paxos-call-chain.dot -o paxos-call-chain.png
|
||
|
|
|
||
|
|
It should do the trick.
|
||
|
|
|

|
Also, for future reference, we consider that:
|
||
|
|
- boxed nodes refer to the Leader;
|
||
|
|
- elliptical nodes refer to the Peon;
|
||
|
|
- diamond shaped nodes refer to state changes;
|
||
|
|
- dotted lines illustrate a message being sent from the Leader to the Peon,
|
||
|
|
or vice-versa.
