During `embark test`, the contracts dapp was throwing an error:

This was due to the fact that during testing, the Ganache VM **provider** is used as the blockchain node, instead of spinning up an instance of Ganache. Due to this, there is no HTTP nor WebSockets RPC endpoint opened on the VM node, and the contracts dapp was not able to connect to the node during tests.
Add `$EMBARK` to the contract config’s `dappConnection` list, so that the contract test dapp can successfully connect to Embark’s proxy, which ultimately communicates with the Ganache VM.
As a side note, without `$EMBARK` in the `dappConnection` list, the tests could run successfully when using `embark test —node=embark`. This succeeds because the geth node exposes the RPC WebSockets endpoint that the contracts app connects to on `ws://localhost:8546`.
This fixes a bug that redeployment of contracts has not been properly
reflected in the cockpit contract list.
The reason for that was that it's listening for a websocket API that
only updates when the `contractsState` event has been emitted.
The commit ensures `contractsState` is emitted during dedicated deployment
events.
Since ee56f37713, any deployment hook that
was using simple `console.log()` statements to output information, would result in
unexpected `[[object object], [object object]]`.
Unfortunately, the reason for that was that we switched from non-arrow functions to
arrow functions [here](ee56f37713 (diff-a7c4cef8bfebeb39fcd092aca5570fecL324-L340)). Usually switching from non-arrow functions to arrow functions solves
a lot of lexical scope issues where the current reference of `this` isn't pointing at the
right thing.
We're tempering with the global `console.log` inside Embark, which then, combined with
**proper** lexical scope, causes the output described above.
Generally there are a few ways to go about this:
1. Ensure that our custom log functions doesn't turn every log statement into an array output
2. Tell users not to use `console.log` inside deployment hooks and instead rely on `deps.logger`
3. Revert the changes made in the mentioned commit and use non-arrow functions inside `interceptLogs`
Option 2) is not really a solution as we can't simply tell our users that they can't use one of
the most used functions in JavaScript. Option 1) requires finding out why we're formatting logs
by default in an array shapre in the first place. On top of that, we might be relying on this
inside Embark, so it could break certain output.
Option 3) seems to be the most pragmatic solution for now as it doesn't introduce any of the
downsides mentioned above at the cost of using non-arrow functions.
This PR replaces #2057.
Implement a collective typecheck action that can be invoked in the root of the
monorepo with `yarn typecheck` or in watch-mode with `yarn watch:typecheck`.
Include the watch-mode typecheck action as part of `yarn start` (a.k.a
`yarn watch`).
To activate collective typecheck for a package in the monorepo, its
`package.json` file should specify:
```
{
"embark-collective": {
"typecheck": true
}
}
```
*-or-*
```
{
"embark-collective": {
"typecheck": {...}
}
}
```
Where `{...}` above is a `tsconfig.json` fragment that will be merged into the
config generated for the package according the same rules that `tsc` applies
when merging [configs][config].
When collective typecheck begins, it generates a `tsconfig.json` for the root
of the monorepo and for each package that is activated for the action. If the
generated JSON is different than what's on disk for the respective root/package
config, or if the config is not present on disk, then it will be
written. Changes to generated `tsconfig.json` files should be committed; such
changes will arise when there are structural changes to the monorepo, e.g. a
package is added, removed, moved and/or the directory containing it is
renamed. Since the configs are only generated at the beginning of collective
typecheck, when structural changes are made in the monorepo `yarn typecheck`
(or `yarn start` or `yarn watch:typecheck`) should be restarted.
Nearly all of the packages in the monorepo (i.e. all those for which it makes
sense) have been activated for collective typecheck. Even those packages that
don't contain `.ts` sources are activated because `tsc` can make better sense
of the code base as a whole owing to the project references included in the
generated `tsconfig.json` files. Also, owing to the fully cross-referenced
`tsconfig.json` files, it's possible for `tsc` to type check the whole code
base without babel (`yarn build` or `yarn watch:build`) having been run
beforehand.
**NOTE** that a *"cold typecheck"* of the whole monorepo is resource intensive:
on this author's 2019 MacBook Pro it takes around three minutes, the fans spin
up, and `tsc` uses nearly 0.5 GB of RAM. However, once a full typecheck has
completed, the next full typecheck will complete in a few seconds or less; and
when running in watch-mode there is likewise a *big* speedup once a full
typecheck has completed, whether that full check happened before it's running
in watch-mode or when watch-mode itself resulted in a full check before
switching automatically to incremental check, as well a corresponding *big*
reduction in resource consumption. A full check will be needed any time
`yarn typecheck` (or `yarn start` or `yarn watch:typecheck`) is run in a fresh
clone plus `yarn install`, or after doing `yarn reboot[:full]` or `yarn reset`.
The combination of options in each generated package-level `tsconfig.json` and
the root `tsconfig.base.json` result in `tsc` writing `.d.ts` files (TypeScript
declaration files) into the `dist/` directory of each package. That
output is intended to live side-by-side with babel's output, and therefore the
`"rootDir"` option in each generated config is set to `"./src"`.
In projects activated for collective typecheck, `.js` may be converted to `.ts`
and/or `.ts` sources may be added without any additional changes needed in
package-level `package.json`.

Reorganize types in `packages/core/typings` (a.k.a `@types/embark`) into
`packages/core/core` (`embark-core`), refactor other packages' imports
accordingly, and delete `packages/core/typings` from the monorepo. This results
in some similarly named but incompatible types exported from `embark-core`
(e.g. `Events` and `EmbarkEvents`, the latter being the one from
`packages/core/typings`); future refactoring should consolidate those types. To
avoid circular dependency relationships it's also necessary to split out
`Engine` from `embark-core` into its own package (`embark-engine`) and to
introduce a bit of duplication, e.g. the `Maybe` type that's now defined in
both `embark-i18n` and `embark-core`.
In the process of the types reorg, move many dependencies spec'd in various
`package.json` to the `package.json` of the package/s that actually depend on
them, e.g. many are moved from `packages/embark/package.json` to
`packages/core/engine/package.json`. Related to those moves, fix some Node.js
`require`-logic related to bug-prone dependency resolution.
Fix all type errors that appeared as a result of activating collective
typecheck across the whole monorepo.
Reactivate `tslint` in `packages/core/core` and fix the remaining linter errors.
Tidy up and add a few items in the root `package.json` scripts.
Bump lerna from `3.16.4` to `3.19.0`.
Bumpt typescript from `3.6.3` to `3.7.2`.
Bumpt tslint from `5.16.0` to `5.20.1`.
Make various changes related to packages' `import`/`require`ing packages that
weren't spec'd in their respective `package.json`. More refactoring is needed
in this regard, but changes were made as the problems were observed in the
process of authoring this PR.

This was caused by the fact that we registered the action to change
the accounts, but that action needs the node accounts, which is
a request to eth_accounts, hence creating a loop
The transaction logger takes care of intercepting any responses coming from the
blockchain proxy, determines what response it's dealing with and then extracts
information from the response to output useful log information to the user, such as
when a contract methods has been called etc.
It turned out that it didn't properly handle cases where value transactions
from account to account (such as done here in [Status Teller](a5ab4d4b26/embarkConfig/data.js (L100-L110))) have been made.
Since Embark couldn't map any of those accounts to actual contracts, while
still having stored corresponding transactions, it logged them as transactions
from "Unknown Smart Contracts".
This commit ensures via heuristics that, if the address a transactions is sent to is
included in any of the nodes accounts, the transaction logger logs a useful message
that a certain value is sent from one to anover account.

It's a relevant `package.json` if the package has a test suite. If `test` isn't
specified then the tests won't run in CI (they have't been running).
Include a fix for one failing test in `packages/plugins/ens` and two failing
test in `packages/stack/deployment`. In all three cases, the mock embark
object's config needed a `blockchainConfig` section with `{ enabled: true }`.
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.
Tests were exiting early and Mocha was reporting an exit code of 0. This allowed CI to complete as if the tests were successful.
Change `compiler:contracts` event request to `compiler:contracts:compile` and update documentation. Because the `compiler:contracts` event didn’t exist, this test was silently failing.
Update the `TestEvents` mock object to allow passing of parameters to an event that is not a callback.
Add unit tests to test for contracts loaded via node_modules.
1. This PR contains a change where any contracts loaded from node_modules will be imported in to `.embark/contracts/node_modules`. Previously, these contracts were loaded in to `.embark/node_modules` (with the `/contracts`).
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`.

It is unnecessary and not a good idea for `packages/embark` to provide
dependencies to other monorepo packages via any kind of transitive dependency
relationship. In this case, `embark` depended on `embark-core` and
`embark-core` needs `embark-whisper-*` packages but it's `embark` that supplies
those packages indirectly. It works out in the monorepo, *probably* in
production too, but we need to move away from that pattern completely.
`Engine.startEngine(cb)` potentially exits the current process if
any registered plugins emits an error in the bootstrap phase.
This limits consumers of this API to react accordingly. Embark's APIs
should be considered library APIs that propagate errors, but let callers
decide what to do with them.
This commit ensures we keep propagating the error of `startEngine()` without
exiting the current process.
Client traffic with the communication provider node, e.g. a whisper node, is
not proxied so make the default port 8547 instead of 8557. It's not a technical
problem for it to be 8557, but our convention to present has been for 855*
ports to be proxied while the upstream is an 854* port.
Update the boilerplate and demo templates to match.
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 using websockets, the simulator was starting on port `8545` instead of `8546`, so the blockchain check was failing.
Update the simulator port to be websockets port from the config when using websockets.
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”.
Improve the reliability of the expiration unit test in the test dapp by explicitly setting the `block.timestamp` and comparing an expiration value against that.
This improves on the current implementation that relies on time passed which varies depending on the speed of unit tests run (CPU speed, logs shown, etc).
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.
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.
