Since goraft/raft@345a74b raftd doesn't compile.

I want to use raftd to run a state machine,how can I do this

Should resp.Body.Close() be done even when there's an error?

I ran this with no leader running:

Hi,

I have done setting GOPATH and installed git also. But after giving command
go get github.com/goraft/raftd

It gives Error and installtion fails. Here is error.

package code.google.com/p/gogoprotobuf/proto: unable to detect version control system for code.google.com/ path package code.google.com/p/goprotobuf/proto: unable to detect version control system for code.google.com/ path

when i add a new url request in line 114 of "raftd/sever/server.go", like s.router.HandleFunc("/nodeState", s.readStateHandle).Method("GET") it went wrong, shows "404 page not found", it is strange.

$ go get github.com/goraft/raftd

I tried to build raftd but failed with following errors.

raftd ✘╹◡╹✘ go get github.com/goraft/raftd
# github.com/goraft/raftd/server
src/github.com/goraft/raftd/server/server.go:68: not enough arguments in call to raft.NewHTTPTransporter

raft.NewHTTPTransporter takes 2nd argument timeout time.Duration, but raftd doesn't pass it. I tried to pass the 2nd argument, building was successful.

I'm guessing this hasn't been updated in a bit and it hasn't kept up with recent go-raft changes.

This might be me doing something wrong, but I was attempting to follow the instructions in the README and I get each system spitting out the "too many open files" error. It looks like each heartbeat is opening a new TCP connection and that is maxing it out. Any idea why this would be happening?

This is the panic, caused by resp.Body.Close() after the HTTP connection fails (resp.Body is nil).

You should move the close after checking the error:

  if err != nil {

  }

Hi,
I am not able to start the multiple instances i.e nodes which will follow the leader.
Please help or you can post video of how you are instantiating multiple servers so that we can also do the same.

I want to use Sourcegraph code search and code review with raftd. A project maintainer needs to enable it to set up a webhook so the code is up-to-date there.

Could you please enable raftd on @sourcegraph by going to https://sourcegraph.com/github.com/goraft/raftd and clicking on Settings? (It should only take 15 seconds.)

Thank you!

When starting a simple 3 node cluster, after about 5-10 minutes, the "leader" dies throwing this error:

Accept error: accept tcp [::]:4001: too many open files

Using debug output, the only thing it shows is a sudden stop when doing:

[raft]01:28:53.821293 peer.heartbeat.flush

I'm not sure where to look. I'm experiencing the same issue in a separate Raft based project and wanted to try the reference implementation which appears to be doing the same thing.

Any ideas?
