As part of 8ed5376533 we made `ENS.getEnsConfig()`
asynchronous, hence it needs a callback. This change was not done in one of the
ENS tests, resulting in the test to fail. The test mocked that particular API,
turning it into noop, which is why the test kept timing out.
This commit fixes the test by not mocking the API and adding the needed configuration
to the environment.
Prior to this commit, registering ENS subdomains would fail due to `defaultAccount`
being null. This is because the underlying API was still relying on `blockchain:defaultAccount:get`.
However since the bigger refactor, every plugin/module is in charge of creating its own
blockchain connector instance and ensuring it has a default account.
This commit makes use of ENS' module's `webDefaultAccount` async getter to
ensure a valid default account is set when registering an ENS subdomain.
Add back DevTxs.
DevTxs sends a zero-value tx to push through any pending txs that may get stuck with geth while in `—dev` mode.
When the geth client is running, devtxs is started automatically, sending a transaction every 10 seconds.
Converted the legacy code in to typescript.
Re-enable debugger for cockpit and console.
Add missing request `blockchain:getTransaction` required to start a debugging session.
Fix error in console when stopping a debug session.
Add option in communication config to choose which Whisper client to use.
Because Parity’s implementation of Whisper is not compatible with Whisper v6, and therefore web3.js in its current form, the following changes have been made:
1. remove any functionality associated with launching a Parity Whisper process.
2. Warn the user when the Parity Whisper client has been opted for in the communication config.
3. Return an error for API calls when Parity Whisper client has been opted for in the communication config.
4. Update Cockpit’s Communication module to show errors returned from API calls.
5. Update the messaging configuration documentation for the new communication client option.
Users can turn of blockchain support if they want to using the blockchain.js
configuration. In practice however, this has never properly worked as several
places in Embark's codebase weren't actually honoring that configuration value.
This commit introduces the necessary changes so that disabling blockchain support will:
No longer generate blockchain related EmbarkJS artifacts
No longer try to deploy Smart Contracts but still compile them
This commit removes the need for `EmbarkJS.onReady()` and `EmbarkJS.Blockchain.blockchainConnector` APIs
in the ENS provider implementation and instead relies purely on vanilla `Web3`. This comes
with the effect that `EmbarkJS.Names` needs to figure out itself what to connect
to, as well as when a connection has been established.
To make that possible, `EmbarkJS.Names` now implements a similar algorithm to
`EmbarkJS.Blockchain` that tries to connect different endpoint, given a `dappConnection`
configuration.
If no `dappConnection` configuration is given via `namesystem.json`, Embark will fallback
to the same connection list that's provided in `contracts.js|json`.

1. get rid of the whisper layer and handle everything in the communication layer
2. Create a gethWhisper and a parityWhisper plugin that has the same files as packages/embark/src/lib/modules/geth, except with a whisperClient instead of gethClient, and will include most of https://github.com/embark-framework/embark/blob/master/packages/plugins/whisper/src/index.js.
3. Get rid of any whisper registration in geth.
4. In the whisperGeth and whisperParity plugins, modify the request for communication:node:register, to end up calling `startWhisperNode`
When whisper was being started in a new process, the message displayed in the console was “Starting Blockchain node in another process”. This is misleading as it is the same message that geth/parity use to start up their processes.
Update whisper initialisation process messaging so it states “Starting Whisper node in another process”.
When `eth_unsubscribe` is received in the proxy, ensure this request is forwarded through on the correct socket (the same socket that was used for the corresponding `eth_subscribe`).
Move subscription handling for `eth_subscribe` and `eth_unsubscribe` to RpcModifiers (in `rpc-manager` package).
For each `eth_subscribe` request, a new `RequestManager` is created. Since the endpoint property on the proxy class was updated to be a provider, the same provider was being assigned to each new `RequestManager` and thus creating multiple event handlers for each subscription created. To circumvent this, we are now creating a new provider for each `RequestManager`.

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.
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.
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.
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.
* fix(@embark/solidity): fix solidity ipc connection with blockchain
When blockchain was run in another process, the IPC was connected,
but the compiler was not loaded, so the IPC calls never returned
* fix(@embark/geth): fix cb is not a fn because it needs request2
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.
