Adds pub/sub of incoming Pss messages using event.Feed,
and a websockets interface for pss send and notifications
through persistent connection using rpc.notifier.
Websocket RPC are started automatically on the swarm executable
if the --pss flag is present. If more instances are to be run,
alternate ws ports can be specified with the --pssport flag.
Current implementation also includes a shallow builtin ping/pong handler
with topic "pss" and version 1, to simplify POCs and testing against pss.
This will eventually be removed, so no code should be made dependent on it.
General:
- Message encapsulation is temporary until integration with whisper
Incoming message handling:
- Implements a dispatcher for registering handler functions to pss topics
- Handlers can be any sort of function, and can send/receive on p2p.MsgReadWriter
- Actual p2p.Protocol handling now as pluggable convenience function
Sending and routing:
- Added temporary cache solution based on message hash digest
- Send and forward split up as separate methods
- Send is now payload agnostic (p2p.Protocol replies massaged in p2p.MsgWriter)
Tests:
- TestPssRandom...
Sends PSS between randomly selected nodes in different population magnitudes
- TestPssFullLinearEcho
A->B->C->B->A ping/pong over pss, where A and C are running pss
- TestPssFullRandom50Pct
10 nodes where 5 are running pss, 5 sends to/from random nodes
(messages currently get stuck in kad. routing, discarded by cache block)
- Protocoltester tests status unknown
* Conceals rw in messenger type
* Adds generic remote control for nodes in network sim
* Adds msg type and event to sim, journal
* Msg http output, http options handler
* Msg event added to "cytoscape" for output to visualizer
* Msg event structure changed to fit "cytodata" logic
* Fix for handling CORS/PUT requests:
* fallthrough OPTIONS method handler
* Access-Control-Allow-Methods header added (note that the servermux panics if sent empty method value through http)
Pointer rcvr incompatible with protocols.NewPeer
p2p: Removed duplicate declaration of Messenger interface
p2p/protocols,swarm/network: Codemap primitive type correction
Codemap was using uint for message types
But Messenger.SendMsg needs uint64

- Moved fuse related code in a new package, swarm/fuse
- Added write support
- Create new files
- Delete existing files
- Append to files (with limitations)
- More test coverage
This PR deprecates the file related RPC calls in favour of an improved HTTP API.
The main aim is to expose a simple to use API which can be consumed by thin
clients (e.g. curl and HTML forms) without the need for complex logic (e.g.
manipulating prefix trie manifests).
This adds a swarm ls command which lists files and directories stored in a
manifest. Rather than listing all files, it uses "directory prefixes" in case there are a
lot of files in a manifest but you just want to traverse it.
This also includes some refactoring to the tests and the introduction of a
swarm/api/client package to make things easier to test.
* swarm/api: fix build/tests on unsupported platforms
Skip FUSE tests if FUSE is unavailable and change build constraints so
the 'lesser' platforms aren't mentioned explicitly. The test are
compiled on all platforms to prevent regressions in _fallback.go
Also gofmt -w -s because why not.
* internal/web3ext: fix swarmfs wrappers
Remove inputFormatter specifications so users get an error
when passing the wrong number of arguments.
* swarm/api: improve FUSE-related logging and APIs
The API now returns JSON objects instead of strings.
Log messages for invalid arguments are removed.
There is no need to depend on the old context package now that the
minimum Go version is 1.7. The move to "context" eliminates our weird
vendoring setup. Some vendored code still uses golang.org/x/net/context
and it is now vendored in the normal way.
This change triggered new vet checks around context.WithTimeout which
didn't fire with golang.org/x/net/context.
