Add support for *connecting to* Quorum blockchains. This plugin will not start a Quorum node or nodes automatically as Embark does with other chains.
This plugins supports deploying contracts publically and privately using the Tessera private transaction manager.
This plugin supports sending of public and private transactions using the Tessera private transaction manager.
Add ability to skip bytecode checking as part of the contract deployment process. Instruct the deployer to skip checking if the contract bytecode exists on-chain before deploying the contract. This is important in the case of having many private nodes in a network because if a contract is deployed privately to node 1 and 7, running Embark on node 2 should skip the bytecode check as the contract *is not* deployed on node 2, nor do we want it deployed on node 2. If the bytecode check was in place, Embark would have deployed it to node 2 and therefore not adhered to the privacy needs.
Add Ethereum contract deployer for Quorum, allowing for deploying of public and private contracts using `privateFor` and `privateFrom` (see Contract config updates below).
Add web3 extensions enabling specific functionality for Quorum. Extensions includes those provided by [`quorum-js`](https://github.com/jpmorganchase/quorum.js), as well as some custom monkeypatches that override web3 method output formatting, including:
- web3.eth.getBlock
- web3.eth.getTransaction
- web3.eth.getTransactionReceipt
- web3.eth.decodeParameters
DApps wishing to take advantage of these overrides will need to patch web3 as follows:
```
import {patchWeb3} from "embark-quorum";
import Web3 from "web3";
let web3 = new Web3(...);
web3 = patchWeb3(web3);
```
Add support for sending a raw private transaction in the Quorum network. This includes running actions from the proxy after an `eth_sendTransaction` RPC request has been transformed in to `eth_sendRawTransaction` after being signed.
fix(@embark/transaction-logger): Fix bug when sending a 0-value transaction.
Add `originalRequest` to the proxy when modifying `eth_sendTransaction` to `eth_sendRawTransaction`, so that the original transaction parameters (including `privateFor` and `privateFrom`) can be used to sign a raw private transaction in the `eth_sendRawTransaction` action.
Added the following properties on to blockchain config:
- *`client`* `{boolean}` - Allows `quorum` to be specified as the blockchain client
- *`clientConfig/tesseraPrivateUrl`* `{string}` - URL of the Tessera private transaction manager
```
client: "quorum",
clientConfig: {
tesseraPrivateUrl: "http://localhost:9081" // URL of the Tessera private transaction manager
}
```
Added the following properties to the contracts config:
- *`skipBytecodeCheck`* `{boolean}` - Instructs the deployer to skip checking if the bytecode of the contract exists on the chain before deploying the contract. This is important in the case of having many private nodes in a network because if a contract is deployed privately to node 1 and 7, running Embark on node 2 should skip the bytecode check as the contract *is not* deployed on node 2, nor do we want it deployed on node 2. If the bytecode check was in place, Embark would have deployed it to node 2 and therefore not adhered to the privacy needs.
- *`privateFor`* `{string[]}` - When sending a private transaction, an array of the recipient nodes' base64-encoded public keys.
- *`privateFrom`* `{string}` - When sending a private transaction, the sending party's base64-encoded public key to use
```
environment: {
deploy: {
SimpleStorage: {
skipBytecodeCheck: true,
privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc"],
privateFrom: "BULeR8JyUWhiuuCMU/HLA0Q5pzkYT+cHII3ZKBey3Bo="
}
}
},
```
- *`proxy:endpoint:http:get`* - get the HTTP endpoint of the proxy regardless of blockchain settings
- *`proxy:endpoint:ws:get`* - get the WS endpoint of the proxy regardless of blockchain settings
- *`runcode:register:<variable>`* - when variables are registered in the console using `runcode:register`, actions with the name of the variable (ie `runcode:register:web3`) will be run *before* the variable is actually registered in the console. This allows a variable to be modified by plugins before being registered in the console.
`embark-snark` has been updated such that it can be used, in conjunction with `embarkjs-snark`, in the console, and in the DApp.
This could, for example, be used to build a dapp like https://tornado.cash.
Please see the README for usage instructions.
Updated tests were excluded in this PR as a consideration for time already spent on getting this library completed. Tests should be updated in a future PR.
Many packages in the monorepo did not specify all of their dependencies; they
were effectively relying on resolution in the monorepo's root
`node_modules`. In a production release of `embark` and `embark[js]-*` packages
this can lead to broken packages.
To fix the problem currently and to help prevent it from happening again, make
use of the `eslint-plugin-import` package's `import/no-extraneous-dependencies`
and `import/no-unresolved` rules. In the root `tslint.json` set
`"no-implicit-dependencies": true`, wich is the tslint equivalent of
`import/no-extraneous-dependencies`; there is no tslint equivalent for
`import/no-unresolved`, but we will eventually replace tslint with an eslint
configuration that checks both `.js` and `.ts` files.
For `import/no-unresolved` to work in our monorepo setup, in most packages add
an `index.js` that has:
```js
module.exports = require('./dist'); // or './dist/lib' in some cases
```
And point `"main"` in `package.json` to `"./index.js"`. Despite what's
indicated in npm's documentation for `package.json`, it's also necessary to add
`"index.js"` to the `"files"` array.
Make sure that all `.js` files that can and should be linted are in fact
linted. For example, files in `packages/embark/src/cmd/` weren't being linted
and many test suites weren't being linted.
Bump all relevant packages to `eslint@6.8.0`.
Fix all linter errors that arose after these changes.
Implement a `check-yarn-lock` script that's run as part of `"ci:full"` and
`"qa:full"`, and can manually be invoked via `yarn cylock` in the root of the
monorepo. The script exits with error if any specifiers are found in
`yarn.lock` for `embark[js][-*]` and/or `@embarklabs/*` (with a few exceptions,
cf. `scripts/check-yarn-lock.js`).
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

Also make a few more revisions:
Revise the "write logs" testing strategy such that it's not necessary for the
logger functions to take an optional callback.
Drop unused `tmp` package from `packages/core/logger` since it's not used in
the tests.
Strip colors before writing to the log file, use a two-space delimiter between
sections of each logged line in the log file, and collapse whitespace in the
message section of each line. These changes make the log file more amenable to
being processed with cli tools such as awk, cut, etc. It's also possible in a
text editor to replace `' '` with `\t` and then load the file in a spreadsheet,
with each line-section in its own column.
Rearrange the sections of each logged line so that it's easier to read, and
only include the origin if the loglevel is debug or trace.
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 follows on PR #2227.
Satisfy new peer dependencies following the bumps: `@storybook/core`,
`regenerator-runtime`.
Follow storybook's instructions to add `@storybook/preset-create-react-app` as
a dependency and also add the needed `.storybook/main.js` in
`packages/cockpit/ui/`.
Storybook is sensitive to presets being in the immediate project's
`node_modules` so add a `"nohoist"` in the root `package.json` for
`"embark-ui/@storybook/**"`.
After making the changes above, problems related to babel were observed when
running `yarn start`. It has been known for some time that having the root
babel config's dependencies spec'd in
`packages/utils/collective/package.json` (which is the package that actually
drives the babel cli) could lead to problems related to deduping, but such
problems hadn't been experienced until now. Move the dependencies relevant to
the root `babel.config.js` into the root `package.json` and update the
explanatory comment in the config.
Make various related changes to templates, tests, etc. The methodology for
finding files that needed changes was to search through the whole monorepo for
the strings "solc" and "solidity" and then inspect the hits to see whether
changes were needed/appropriate.
Remove `solc` as a dependency in `packages/embark/package.json` so that it's
only a proper dependency in `packages/plugins/solidity/package.json`. Adjust
how the "bundled" `solc` package's version is determined, i.e. inspect the
`package.json` of `embark-solidity` instead of `embark`.
When `solc`'s version is `>=0.6.0` use the [new callback API][api].
[api]: https://github.com/ethereum/solc-js/blob/master/README.md#example-usage-with-import-callback
Also, in `dapps/tests/contracts` move the `this.timeout(0);` inside the
`it(...)` for the expensive gas esimation (involving
`SimpleStorage.methods.set`) because it otherwise doesn't seem to have an
effect on the default 15 second timeout.
