Both, `httpProxy` and `wsProxy` inside `Proxymanager` have been assigned
the value of `new Proxy(...).serve()` which is an instance of `express`.
This was wrong and causes runtime errors when proxies are being stopped as
they don't have a `stop()` API.
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.
Managing account details inside of the RPC Manager became a bit convulted and difficult to follow due to any web3 requests inside of an `RpcModifier` communicating over the proxy and therefore to other `RpcModifier`’s or itself. It also created cases where node accounts were duplicated by way of running the `eth_accounts` modifier multiple times (the first time getting accounts from the node and subsequent times getting accounts from the modified `eth_accounts` response.
This has been simplified by having the entry point of the `rpc-manager` (`index.js`) talk directly to the node via `web3`. This allowed account/nodeAccount management to also be handled by the entry point, removing the need for each individual `RpcModifier` from having to handle these account details. The result is a much more simplified and and much easier to maintain code for RPC Manager.
The cases for which accounts can be modified (via `personal_newAccount` RPC call, and via test configuration change) are now handled in one place (the entry point) and propagated to the each `RpcModifier`.
Add `blockchain:started` command to request when the blockchain has been started. In this case, this is needed so that we know when we can create a direct connection to the node, instead of the proxy (as is the case in almost all other modules).
Extend action timeout when in debug mode.
1. These changs have made the `RpcModifier` base class essentially useless, however, it has been kept in place because it will be used for future DRY improvements to the `rpc-manager`.
2. These changes have been tested with the following DApps:
- Demo
- Test DApp
- Contracts test DApp
- Teller
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`).
fix(@embark/proxy): up max listener for proxy request manager
In the tests, we had warnings about max listeners reached, because
the default limit is 10. So I upped the limit for the request
manager and the WS connection.
stoopid CI
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
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.
## User reported error
i recently updated to embark 5.0 im having issues connecting to a local node each time i connect to it i get the following output from the embark console
```
Error during proxy setup: Port should be >= 0 and < 65536. Received 754510.. Use '--loglevel debug' for more detailed information.
```
This is what i have under the blockchain.js file
```
localDev: {
endpoint: "http://127.0.0.1:7545",
accounts: [{
nodeAccounts: true,
}]
}
```
### Problem
The port to start the proxy on is incremented by a constant value (using the `+` operator), however the port comes from the config and in the case where it is a string, the `+` operator acts as a string concatentation.
### Fix
Ensure the port from the config is always parsed to a number before attempting to add the constant proxy port offset.
