See the discussion below. A future commit will implement the closer
change below, and rebase this one on top.
<•jbenet> `n.Diagnostics.GetDiagnostic(time.Second * 20)` is not being respected. should it use a context instead? or is it a timeout because the timeout is sent to other nodes?
<•jbenet> oh it's that the io doesnt respect the context so we're stuck waiting for responses.
<•jbenet> this is that complex interface point between the world of contexts, and the world of io. ctxutil.Reader/Writer is made for this, but you have to make sure to defer close the stream. (see how dht_net uses it). i'd love to find a safer interface. not sure what it is, but we have to a) respect contexts, and b) allow using standard io.Reader/Writers. Maybe TRTTD
<•jbenet> is have ctxutil.Reader/Writer take ReadCloser and WriteClosers and always close them. the user _must_ pass an ioutil. NopCloser to avoid ctxutil closing on you when you dont want it to.
<•jbenet> this seems safer to me in the general case.
d3view is now in its own repo:
https://github.com/jbenet/ipfs-diag-net-d3-vis
This is so we can iterate on it quickly without having to
needlessly waste CI resources.
The repo also installs it for you:
```sh
git clone github.com/jbenet/ipfs-diag-net-d3-vis d3view
cd d3view
sudo make install
```
Try it out:
```
ipfs net diag --vis=d3 | diagnostics/d3/d3view
```
Notes: this is not the best way to do it, because it
breaks `--encoding=json`. Not sure what the best way is, and
right now this provides more utility than the other.
I think it's time to move a lot of the peer-to-peer networking
but-not-ipfs-specific things into its own package: p2p.
This could in the future be split off into its own library.
The first thing to go is the peer.
this is a major refactor of the entire codebase
it changes the monolithic peer.Peer into using
a peer.ID and a peer.Peerstore.
Other changes:
- removed handshake3.
- testutil vastly simplified peer
- secio bugfix + debugging logs
- testutil: RandKeyPair
- backpressure bugfix: w.o.w.
- peer: added hex enc/dec
- peer: added a PeerInfo struct
PeerInfo is a small struct used to pass around a peer with
a set of addresses and keys. This is not meant to be a
complete view of the system, but rather to model updates to
the peerstore. It is used by things like the routing system.
- updated peer/queue + peerset
- latency metrics
- testutil: use crand for PeerID gen
RandPeerID generates random "valid" peer IDs. it does not
NEED to generate keys because it is as if we lost the key
right away. fine to read some randomness and hash it. to
generate proper keys and an ID, use:
sk, pk, _ := testutil.RandKeyPair()
id, _ := peer.IDFromPublicKey(pk)
Also added RandPeerIDFatal helper
- removed old spipe
- updated seccat
- core: cleanup initIdentity
- removed old getFromPeerList
