Re: [PATCH v2 2/3] graph: add support for node free API

By the way, I don't know where to consult about this issue at the moment.
Please forgive me for discussing this issue here. Can we set up a chat box on 
this
page instead of having to comment through email or git send email? Many email 
clients
cannot set the In Reply To header or do not currently have a git send email 
environment,
which is not conducive to the timeliness and convenience of comments.
