This commit introduces a new feature that enables users to run (migration) scripts.
Similar to deployment hooks, scripts are functions that may perform operations on newly
deployed Smart Contracts.
Therefore a script needs to export a function that has access to some dependencies:
```
// scripts/001-some-script.js
module.exports = async ({contracts, web3, logger}) => {
...
};
```
Where `contracts` is a map of newly deployed Smart Contract instances, `web3` a blockchain connector
instance and `logger` Embark's logger instance. Script functions can but don't have to be `async`.
To execute such a script users use the newly introduced `exec` command:
```
$ embark exec development scripts/001-some-script.js
```
In the example above, `development` defines the environment in which Smart Contracts are being
deployed to as well as where tracking data is stored.
Alternativey, users can also provide a directory in which case Embark will try to execute every
script living inside of it:
```
$ embark exec development scripts
```
Scripts can fail and therefore emit an error accordingly. When this happens, Embark will
abort the script execution (in case multiple are scheduled to run) and informs the user
about the original error:
```
.. 001_foo.js running....
Script '001_foo.js' failed to execute. Original error: Error: Some error
```
It's recommended for scripts to emit proper instances of `Error`.
(Migration) scripts can be tracked as well but there are a couple of rules to be aware of:
- Generally, tracking all scripts that have been executed by default is not a good thing because
some scripts might be one-off operations.
- OTOH, there might be scripts that should always be tracked by default
- Therefore, we introduce a dedicated `migrations` directory in which scripts live that should be
tracked by default
- Any other scripts that does not live in the specified `migrations` directory will not be tracked **unless**
- The new `--track` option was provided

Remove `bignumber.js` workaround (in the root, from PR #2152) because it's no
longer needed (verified locally).
Remove the `"skipLibCheck"` workaround (in `packages/plugins/solidity-tests`,
from PR #2152) because it's no longer needed (verified locally).
Refactor a typing in `packages/plugins/geth`. What's happening is that in web3
v1.2.4 `sendTransaction` has a return type of `PromiEvent<TransactionReceipt>`
but in v1.2.6 it has a return type of `PromiEvent<TransactionReceipt |
TransactionRevertInstructionError>`.
Compare:
* [v1.2.4/packages/web3-eth/types/index.d.ts#L291-L294](https://github.com/ethereum/web3.js/blob/v1.2.4/packages/web3-eth/types/index.d.ts#L291-L294)
* [v1.2.6/packages/web3-eth/types/index.d.ts#L295-L298](https://github.com/ethereum/web3.js/blob/v1.2.6/packages/web3-eth/types/index.d.ts#L295-L298)
The problem is that the `TransactionRevertInstructionError` type doesn't have a
`transactionHash` property. Since at present the code in
`packages/plugins/geth/src/devtxs.ts` only deals with the success case re:
`sendTransaction`, import the `TransactionReceipt` type from `web3-eth` and
cast the resolved return value's type using TypeScript's `as` operator.
This commit adds two new configuration settings for Smart Contract configuration:
- `interfaces` - Any Smart Contract that represent an interface or is used for inheritance
- `libraries` - Any Smart Contract that is used as a library
This makes the configuration less redundant in cases where otherwise the `deploy`
property has been set to `false`, such as:
```
deploy: {
Ownable: {
deploy: false
},
...
}
```
The above can now be done via:
```
interfaces: ['Ownable'],
deploy: {
...
}
```
Refactor typings as necessary. In order for `bignumber.js` in the root
`node_modules` to not conflict with `@types/bignumber.js`, specify
`"bignumber.js": "5.0.0"` in `devDependencies` and `"embark-ui/bignumber.js"`
in `nohoist` of the root `package.json`.
In `packages/plugins/rpc-manager` switch from callback to promise usage with
respect to `web3.eth.accounts.signTransaction` because of a [bug][bug]
discovered in web3 v1.2.4.
In `packages/plugins/solidity-tests` specialize the tsc compiler options with
`"skipLibCheck": true` because of a problematic web3-related typing in the
`.d.ts` files of the remix-tests package.
Bump ganache-cli from 6.4.3 to 6.7.0 (latest) because 6.4.3 doesn't support
`eth_chainId` but web3 1.2.4 makes use of the `eth_chainId` RPC method (EIP
695).
BREAKING CHANGE: bump embark's minimum supported version of parity from
`>=2.0.0` to `>=2.2.1`. This is necessary since web3 1.2.4 makes use of the
`eth_chainId` RPC method (EIP 695) and that parity version is the earliest one
to implement it.

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.
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`.

As discussed in #2008, the `service on/off` command in Embark's interactive console
is non-functioning. As solving the root of the problem requires a bit more effort
than anticipated, we've decided offline to remove this command for the time-being.
The functionality is already gone, this commit removes the corresponding docs.
BREAKING CHANGE:
node: >=10.17.0 <12.0.0
npm: >=6.11.3
yarn: >=1.19.1
node v10.17.0 is the latest in the 10.x series and is still in the Active LTS
lifecycle. Embark is still not compatible with node's 12.x and 13.x
series (because of some dependencies), otherwise it would probably make sense
to bump our minimum supported node version all the way to the most recent 12.x
release.
npm v6.11.3 is the version that's bundled with node v10.17.0.
yarn v1.19.1 is the most recent version as of the time node v10.17.0 was
released.

* address some of the issues in the code review
* feat(@embark/specialconfigs): introduce dynamic addresses
This commit introduces a new Smart Contract configuration addressHandler
that lets users define a function to "lazily" compute the address of the
Smart Contract in question.
This is useful when a third-party takes care of deploying a dependency
Smart Contract, but the address of that Smart Contract only being available
at run-time.
Example:
```
deploy: {
SimpleStorage: {
fromIndex: 0,
args: [100],
},
OtherContract: {
deps: ['SimpleStorage'],
address: async (deps) => {
// use `deps.contracts.SimpleStorage` to determine address
},
abiDefinition: ABI
},
}
```
In the example above, OtherContract will be deployed after SimpleStorage
because it uses the deps property to define Smart Contracts that it depends
on. All dependencies are exposed on the addressHandler function parameter
similar to deployment hooks.
Closes#1690
Upgrade all dependencies on web3/web3-* v1.0.0-beta.37 to v1.2.1.
Make various adjustments related to the previous convention of
`"web3": "1.0.0-beta"` in `embark.json` signifying that embark's own web3
dependency should be used in dapp builds.
Fix bugs in library manager, including a switch from using the
live-plugin-manager package to using npm in a child process to install
`"versions"` dependencies specified in `embark.json` when a specified version
doesn't match up with embark's own version for that package.
Avoid race conditions when installing `"versions"` by completing all installs
prior to starting other services. If an install fails, then after all the
installs have completed or failed the embark command will exit with error.
Change various comments and update docs to reflect the new default of web3
v1.2.1.
