This PR adds support for EIP-712 (https://github.com/ethereum/EIPs/blob/master/EIPS/eip-712.md), by allowing the signing of typed data transactions using the `eth_signTypeData_v3` or `eth_signTypedData` request.
Add a module called `embark-rpc-manager` to handle all RPC transaction modifications.
The internal events management module extracted to `embark-core`. This allows other modules (ie plugins) to use a private instance of Embark’s event API.
Remove transaction modifications in `embark-accounts-manager` and leave only the functionality in this module that handle account management (ie funding of accounts). Other functionality was moved to `embark-rpc-manager`.
- Transactions should now reflect when a new node account is added via `personal_newAccount` or via the node itself (and once `eth_accounts` is requested).
- In the proxy, errors are handled for all cases and are now JSON-RPC spec-compliant.
- Always register `eth_signTypedData` RPC response and display error message if account cannot be found.
NOTE: Updated yarn.lock due to conflict after rebase.
Avoid race condition with rpc modifications
Refactor proxy to make request handling asynchronous, and to allow circumvention of forwarding requests to the node in cases where it is not needed.
Move loading of plugins to after core and stack components (in cmd_controller).
We should load custom plugins LAST (ie after all core and stack components, and after all Embark plugins). To do this, we disable automatic loading of plugins in the config, and allow them to be loading explicitly in cmd_controller.
Create a system that allows registration of custom plugins. Each plugin is generated in EmbarkJS by instantiating the registered class. For example, we can register a Plasma plugin and it will be generated in to EmbarkJS.Plasma with an instantiation of `embarkjs-plasma`. The DApp itself can then do what it wants with `EmbarkJS.Plasma` (ie call `EmbarkJS.Plasma.init()`.
NOTE: loading of custom plugins needs to be applied to all other commands in `cmd_controller`. This PR only loads custom plugins for the `run` command.
NOTE: This PR is based on branch fix/ws-eth-subscribe (#1850). I will rebase this PR when (and if) #1850 is merged.
In 776db1b7f7 (diff-5cab125016e6d753f03b6cd0241d5ebbR267) we've introduced the ability to add
a `priority` parameter to plugin actions, so the order of actions can be semi-ensured.
That commit also introduced typings for that new API but it actually didn't match the
implementation of the API, namely that the second parameter of `Plugin.registerActionForEvent()`
can be either an options object **or** a callback function.
This forces consumers to call the API as `registerActoniForEvent(name, undefined|null, callback)`
which shouldn't be necessary.
BREAKING CHANGE:
Related to #1985. Prior to Embark's minimum supported version of Node.js being
bumped to to 10.17.0, Embark was incompatible with any relatively recent
release of the `ipfs-http-client` package.
While *internal* changes are needed re: ipfs's `Buffer` export for
e.g. `embark_demo` to function correctly *(and this PR makes those changes)*,
Embark otherwise runs/tests okay.
Keep in mind #2033.
However, if a dApp author were to explicitly `require('ifps-api')` in the
front-end that wouldn't work as before; and swapping `"ipfs-http-client"` for
`"ipfs-api"` might also not be enough — there are API changes that dApp authors
would need to consider, regardless of Embark presently supplying the dependency
and EmbarkJS wrapping around it.
Closes#1994.
Hook `embark-profiler` into the engine's contracts group.
Adjust `request` signatures to match v5 usage.
Ensure gas numbers are formatted consistently in the ascii table.
Display non-json output in cockpit's console as monospace/pre to preserve
profiler table formatting.
Embark's `File.content` is an asynchrononus getter that potentially downloads the
contents of a file from its `externalUrl`. This can potentially fail but is not properly
reported to the user as the error itself is ignored.
This commit ensures errors are propagated and displayed to the user.
The blockchain module should not contain any ethereum-specific code, and currently it contains a check to see if the blockchain has already been started.
This PR moves this check to blockchain client (ie geth or parity). This check function is registered along with the started callback.
style(@embark/stack/blockchain): add missing semicolon
Turns out that, when Embark tries to replace ENS subdomains, it would fail
if `subdomains` aren't defined in the namesystem configuration.
This commit adds a safeguard so that not defining `subdomains` is fine.
This commit fixes the issue that it wasn't possible anymore to use named constructor arguments
in Smart Contract configurations.
For example, the following Smart Contract expects two constructor arguments:
```solidity
contract SomeContract {
constructor(address[] _addresses, int initialValue) public {}
}
```
The first being a list of addresses, the second one a number. This can be configured as:
```js
SomeContract: {
args: [
["$MyToken2", "$SimpleStorage"],
123
]
}
```
Notice how the order of arguments matters here. `_addresses` come first in the constructor,
so they have to be defined first in the configuration as well.
Another way to configure this is using named arguments, which is what's broken prior to this commit:
```js
SomeContract: {
args: {
initialValue: 123,
_addresses: ["$MyToken2", "$SimpleStorage"]
}
}
```
Using a notation like this ^ the order no longer matters as Embark will figure out the right
values for the constructor arguments by their names.
The reason this is broken is because there are several modules in Embark that register and
run a `deployment:contract:beforeDeploy` action, which are allowed to mutate this configuration
object. One of those modules is the `ens` module, which searches for ENS names in the arguments
and figure out whether it has to replace it with a resolved address.
One thing that particular module didn't take into account is that `args` could be either and
array, or an object and will always return an array, changing the shape of `args` in case it was
an object.
This is a problem because another module, `ethereum-blockchain-client`, another action is registered
that takes this mutated object in `determineArguments()` and ensure that, if `args` is actually an
object, the values are put in the correct position matching the constructor of the Smart Contract in
question.
One way to solve this was to use the newly introduced [priority](https://github.com/embark-framework/embark/pull/2031) and ensure
that `ens` action is executed after `ethereum-blockchain-client`'s.
However, the actual bug here is that the ENS module changes the shape of `args` in the first place,
so this commit ensures that it preserves it.
Update event name `"deploy:contract:deployed"` to
`"deployment:contract:deployed"`.
Also, listen one time for `"deployment:deployContracts:afterAll"` and then
request the full contracts list so as to pickup contract names that were
already deployed. This is necessary for subsequent `embark run` (without
reset), otherwise the suggestions list will be missing contracts.
The `WhisperGethClient` returns empty strings for its "new account" and "list
accounts" commands; if a command is an empty string then `Blockchain` should
not execute it.
Previously, in the embark cli dashboard/console, if you were to type `Foo.` and
hit tab for autocomplete then (assuming you hadn't defined `Foo`) there would
be unhandled errors and the console could even become unusable.
Refactor `packages/core/console` and related code so that nothing happens when
you attempt to autocomplete a bad reference (the same behavior as Node's own
REPL).
Also bump peerDeps: @emotion/core from 0.13.1 to 10.0.22 and @emotion/styled
from 0.10.6 to 10.0.23. Satisfy @babel/runtime peerDep with 7.6.3.
Make small refactors in components/FileExplorer and
containers/FileExplorerRowContainer re: the package upgrades.

`embark console` registers and tries to spin up `Cockpit`, even when there's already
a Cockpit instance running and thefore exits with an error that a certain port is already
in use.
This commit ensures that Cockpit is only bootstrapped when `embark console` is
executed as a non-secondary process, meaning that there's no other `embark run`
process active that might occupy Cockpit's default port.
We've introduced a regression in https://github.com/embark-framework/embark/commit/f9557d4c9 where invalid data
has been sent to web3's `ecRecover()` method to verify signed messages.
This causes an internal server error and the utility feature inside Cockpit
unsuable.
This commit ensures that the correct data is sent to `ecRecover()` making verifying
messages through Cockpit functional again.
Fix the proxy’s handling of WebSocket connections when subscribing to contract events and node data using the `eth_subscribe` RPC request.
Previously, the client connection that the subscription data was sent to was often in a closed state. It was determined that this connection was the wrong connection to forward the data in the first place. The connection was in fact generally the connection created for the Ethereum service check which was then (correctly and subsequently) closed after it had finished its operation.
The flow of a proxy request handling a WebSocket “eth_subscribe” RPC request is now as follows:
1. A WebSocket RPC request `”eth_subscribe”` is sent from a client to the proxy.
2. Proxy forwards the request to the node by way of a new instance of `RequestManager`.
3. When the node receives an event matching the subscription, it sends the event data back to same socket connection it received the request on (ie the specific instance of `RequestManager`).
4. The `RequestManager` fires the `”data”` event containing the subscription data, and this event is picked up in the proxy.
5. The proxy then forwards the subscription data on to the originating WS client connection.
All other requests (ie non-WS or WS RPC requests that are not `eth_subscribe`) will be serviced to/from the node using a single `RequestManager` instance.
