# Debian Packaging
|
||||
|
||||
Tagged releases and develop branch commits are available as installable Debian packages
|
||||
for Ubuntu. Packages are built for the all Ubuntu versions which are supported by
|
||||
Canonical:
|
||||
|
||||
- Trusty Tahr (14.04 LTS)
|
||||
- Xenial Xerus (16.04 LTS)
|
||||
- Yakkety Yak (16.10)
|
||||
- Zesty Zapus (17.04)
|
||||
|
||||
Packages of develop branch commits have suffix -unstable and cannot be installed alongside
|
||||
the stable version. Switching between release streams requires user intervention.
|
||||
|
||||
The packages are built and served by launchpad.net. We generate a Debian source package
|
||||
for each distribution and upload it. Their builder picks up the source package, builds it
|
||||
and installs the new version into the PPA repository. Launchpad requires a valid signature
|
||||
by a team member for source package uploads. The signing key is stored in an environment
|
||||
variable which Travis CI makes available to certain builds.
|
||||
|
||||
We want to build go-ethereum with the most recent version of Go, irrespective of the Go
|
||||
version that is available in the main Ubuntu repository. In order to make this possible,
|
||||
our PPA depends on the ~gophers/ubuntu/archive PPA. Our source package build-depends on
|
||||
golang-1.9, which is co-installable alongside the regular golang package. PPA dependencies
|
||||
can be edited at https://launchpad.net/%7Eethereum/+archive/ubuntu/ethereum/+edit-dependencies
|
||||
|
||||
## Building Packages Locally (for testing)
|
||||
|
||||
You need to run Ubuntu to do test packaging.
|
||||
|
||||
Add the gophers PPA and install Go 1.9 and Debian packaging tools:
|
||||
|
||||
$ sudo apt-add-repository ppa:gophers/ubuntu/archive
|
||||
$ sudo apt-get update
|
||||
$ sudo apt-get install build-essential golang-1.9 devscripts debhelper
|
||||
|
||||
Create the source packages:
|
||||
|
||||
$ go run build/ci.go debsrc -workdir dist
|
||||
|
||||
Then go into the source package directory for your running distribution and build the package:
|
||||
|
||||
$ cd dist/ethereum-unstable-1.6.0+xenial
|
||||
$ dpkg-buildpackage
|
||||
|
||||
Built packages are placed in the dist/ directory.
|
||||
|
||||
$ cd ..
|
||||
$ dpkg-deb -c geth-unstable_1.6.0+xenial_amd64.deb

# devp2p Simulations
|
||||
|
||||
The `p2p/simulations` package implements a simulation framework which supports
|
||||
creating a collection of devp2p nodes, connecting them together to form a
|
||||
simulation network, performing simulation actions in that network and then
|
||||
extracting useful information.
|
||||
|
||||
## Nodes
|
||||
|
||||
Each node in a simulation network runs multiple services by wrapping a collection
|
||||
of objects which implement the `node.Service` interface meaning they:
|
||||
|
||||
* can be started and stopped
|
||||
* run p2p protocols
|
||||
* expose RPC APIs
|
||||
|
||||
This means that any object which implements the `node.Service` interface can be
|
||||
used to run a node in the simulation.
|
||||
|
||||
## Services
|
||||
|
||||
Before running a simulation, a set of service initializers must be registered
|
||||
which can then be used to run nodes in the network.
|
||||
|
||||
A service initializer is a function with the following signature:
|
||||
|
||||
```go
|
||||
func(ctx *adapters.ServiceContext) (node.Service, error)
|
||||
```
|
||||
|
||||
These initializers should be registered by calling the `adapters.RegisterServices`
|
||||
function in an `init()` hook:
|
||||
|
||||
```go
|
||||
func init() {
|
||||
adapters.RegisterServices(adapters.Services{
|
||||
"service1": initService1,
|
||||
"service2": initService2,
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
## Node Adapters
|
||||
|
||||
The simulation framework includes multiple "node adapters" which are
|
||||
responsible for creating an environment in which a node runs.
|
||||
|
||||
### SimAdapter
|
||||
|
||||
The `SimAdapter` runs nodes in-memory, connecting them using an in-memory,
|
||||
synchronous `net.Pipe` and connecting to their RPC server using an in-memory
|
||||
`rpc.Client`.
|
||||
|
||||
### ExecAdapter
|
||||
|
||||
The `ExecAdapter` runs nodes as child processes of the running simulation.
|
||||
|
||||
It does this by executing the binary which is running the simulation but
|
||||
setting `argv[0]` (i.e. the program name) to `p2p-node` which is then
|
||||
detected by an init hook in the child process which runs the `node.Service`
|
||||
using the devp2p node stack rather than executing `main()`.
|
||||
|
||||
The nodes listen for devp2p connections and WebSocket RPC clients on random
|
||||
localhost ports.
|
||||
|
||||
### DockerAdapter
|
||||
|
||||
The `DockerAdapter` is similar to the `ExecAdapter` but executes `docker run`
|
||||
to run the node in a Docker container using a Docker image containing the
|
||||
simulation binary at `/bin/p2p-node`.
|
||||
|
||||
The Docker image is built using `docker build` when the adapter is initialised,
|
||||
meaning no prior setup is necessary other than having a working Docker client.
|
||||
|
||||
Each node listens on the external IP of the container and the default p2p and
|
||||
RPC ports (`30303` and `8546` respectively).
|
||||
|
||||
## Network
|
||||
|
||||
A simulation network is created with an ID and default service (which is used
|
||||
if a node is created without an explicit service), exposes methods for
|
||||
creating, starting, stopping, connecting and disconnecting nodes, and emits
|
||||
events when certain actions occur.
|
||||
|
||||
### Events
|
||||
|
||||
A simulation network emits the following events:
|
||||
|
||||
* node event - when nodes are created / started / stopped
|
||||
* connection event - when nodes are connected / disconnected
|
||||
* message event - when a protocol message is sent between two nodes
|
||||
|
||||
The events have a "control" flag which when set indicates that the event is the
|
||||
outcome of a controlled simulation action (e.g. creating a node or explicitly
|
||||
connecting two nodes together).
|
||||
|
||||
This is in contrast to a non-control event, otherwise called a "live" event,
|
||||
which is the outcome of something happening in the network as a result of a
|
||||
control event (e.g. a node actually started up or a connection was actually
|
||||
established between two nodes).
|
||||
|
||||
Live events are detected by the simulation network by subscribing to node peer
|
||||
events via RPC when the nodes start up.
|
||||
|
||||
## Testing Framework
|
||||
|
||||
The `Simulation` type can be used in tests to perform actions in a simulation
|
||||
network and then wait for expectations to be met.
|
||||
|
||||
With a running simulation network, the `Simulation.Run` method can be called
|
||||
with a `Step` which has the following fields:
|
||||
|
||||
* `Action` - a function which performs some action in the network
|
||||
|
||||
* `Expect` - an expectation function which returns whether or not a
|
||||
given node meets the expectation
|
||||
|
||||
* `Trigger` - a channel which receives node IDs which then trigger a check
|
||||
of the expectation function to be performed against that node
|
||||
|
||||
As a concrete example, consider a simulated network of Ethereum nodes. An
|
||||
`Action` could be the sending of a transaction, `Expect` it being included in
|
||||
a block, and `Trigger` a check for every block that is mined.
|
||||
|
||||
On return, the `Simulation.Run` method returns a `StepResult` which can be used
|
||||
to determine if all nodes met the expectation, how long it took them to meet
|
||||
the expectation and what network events were emitted during the step run.
|
||||
|
||||
## HTTP API
|
||||
|
||||
The simulation framework includes a HTTP API which can be used to control the
|
||||
simulation.
|
||||
|
||||
The API is initialised with a particular node adapter and has the following
|
||||
endpoints:
|
||||
|
||||
```
|
||||
GET / Get network information
|
||||
POST /start Start all nodes in the network
|
||||
POST /stop Stop all nodes in the network
|
||||
GET /events Stream network events
|
||||
GET /snapshot Take a network snapshot
|
||||
POST /snapshot Load a network snapshot
|
||||
POST /nodes Create a node
|
||||
GET /nodes Get all nodes in the network
|
||||
GET /nodes/:nodeid Get node information
|
||||
POST /nodes/:nodeid/start Start a node
|
||||
POST /nodes/:nodeid/stop Stop a node
|
||||
POST /nodes/:nodeid/conn/:peerid Connect two nodes
|
||||
DELETE /nodes/:nodeid/conn/:peerid Disconnect two nodes
|
||||
GET /nodes/:nodeid/rpc Make RPC requests to a node via WebSocket
|
||||
```
|
||||
|
||||
For convenience, `nodeid` in the URL can be the name of a node rather than its
|
||||
ID.
|
||||
|
||||
## Command line client
|
||||
|
||||
`p2psim` is a command line client for the HTTP API, located in
|
||||
`cmd/p2psim`.
|
||||
|
||||
It provides the following commands:
|
||||
|
||||
```
|
||||
p2psim show
|
||||
p2psim events [--current] [--filter=FILTER]
|
||||
p2psim snapshot
|
||||
p2psim load
|
||||
p2psim node create [--name=NAME] [--services=SERVICES] [--key=KEY]
|
||||
p2psim node list
|
||||
p2psim node show <node>
|
||||
p2psim node start <node>
|
||||
p2psim node stop <node>
|
||||
p2psim node connect <node> <peer>
|
||||
p2psim node disconnect <node> <peer>
|
||||
p2psim node rpc <node> <method> [<args>] [--subscribe]
|
||||
```
|
||||
|
||||

# devp2p simulation examples
|
||||
|
||||
## ping-pong
|
||||
|
||||
`ping-pong.go` implements a simulation network which contains nodes running a
|
||||
simple "ping-pong" protocol where nodes send a ping message to all their
|
||||
connected peers every 10s and receive pong messages in return.
|
||||
|
||||
To run the simulation, run `go run ping-pong.go` in one terminal to start the
|
||||
simulation API and `./ping-pong.sh` in another to start and connect the nodes:
|
||||
|
||||
```
|
||||
$ go run ping-pong.go
|
||||
INFO [08-15|13:53:49] using sim adapter
|
||||
INFO [08-15|13:53:49] starting simulation server on 0.0.0.0:8888...
|
||||
```
|
||||
|
||||
```
|
||||
$ ./ping-pong.sh
|
||||
---> 13:58:12 creating 10 nodes
|
||||
Created node01
|
||||
Started node01
|
||||
...
|
||||
Created node10
|
||||
Started node10
|
||||
---> 13:58:13 connecting node01 to all other nodes
|
||||
Connected node01 to node02
|
||||
...
|
||||
Connected node01 to node10
|
||||
---> 13:58:14 done
|
||||
```
|
||||
|
||||
Use the `--adapter` flag to choose the adapter type:
|
||||
|
||||
```
|
||||
$ go run ping-pong.go --adapter exec
|
||||
INFO [08-15|14:01:14] using exec adapter tmpdir=/var/folders/k6/wpsgfg4n23ddbc6f5cnw5qg00000gn/T/p2p-example992833779
|
||||

|
||||
```
