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.
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`).
Set Ganache as a blockchain client that doesn't need to be started.
Set it as the default client, at least for development.
Move all blockchain related stuff in the blockchain component
Includes a fix by @emmizle to fix the WS connection in the proxy
Adds back the watch on contract events and writes them to a file
with the same method as contract logs from transaction-logger, so
I extracted those methods to utils/file so that both could use the
same functions.
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.
