## 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.
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.
When we introduced dappConnection to ENS, we didn't add the concept
of auto connection, like we do in the "normal" connection. This
means that when using $WEB3, the contracts connection waited for
the user to click on a button, but the ENS part called `ethereum.enable`
directly, which is confusing for the dev, because we specified to
NOT automatically connect to ethreum.
This fixes it by checking the dappAutoEnable property in contracts
config and adds it to the namesystemConfig artifact
And remove `suggestions.json` in the `"files"` list of
`packages/core/console/package.json` since it was moved to
`packages/plugins/suggestions/suggestions.json`.
Remove the `<12.0.0` restriction re: Node.js version in the `"engines"`
settings for all the packages in the monorepo that had that restriction.
Add missing `"engines"` settings in `packages/plugins/snark/package.json`.
Adjust the Azure Pipelines config to include builds for Node.js v12.x and
v13.x.
Bump `solc` to `0.4.26` in `dapps/tests/app` and `dapps/tests/contracts`. It
was discovered that older versions suffered a fatal `Maximum call stack size
exceeded` error when run on Windows with Node.js v12.x or newer. Display a
warning re: the bad combo (solc version + Windows + Node version) if it's
detected at runtime.
Adjust the root `yarn.lock` so that the `sha3` transitive dependency resolves
to a newer version that is compatible with Node v13.x.
Fixes the use of Infura to connect to the ENS contracts. When
connecting directly to Infura, it would throw with `rejected due to
project ID settings`, because it doesn't accept the VM as the domain
Instead, when passing from the proxy, it works. So I changed the
default when no dappConnection to ['$EMBARK']. I also added a
message when the error happens to help users fix it themselves
When in the testnet, we don,t register because we already have the
addresses, which is fine, but we also didn't populate the ensConfig
object which contains the important information about the addresses
and ABI.
There was a lot of lint problems in a couple of files so I cleaned
that up
## Problem
Doing read, then write each a trasaction or call exectues could get
heavy, especially with regular txs on
This was especially true in the tests, which led to deactivate the
tx logger in the tests
## Solution
Instead of reading the whole file, adding the JSON line a writing,
we instead just append some pseudo JSON to it that later gets read
and parsed correctly back to JSON
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: {
...
}
```
This commit introduces a new `global.getEvmVersion()` that can be used to
conditionally run tests, such as when tests rely on RPC APIs that are only
available in specific evm nodes.
When running tests that expect the EVM to fail, Embark's proxy keeps logging
the VM errors to stdout making it look like tests weren't successful, while they
are actually passing.
Inside a test-runner it's probably expected not to see any error logs when the
tests in question expect errors.
This commit changes the proxy to use `debug()` logs instead of `error()`, making
it configurable through log verbosity how much errors are seen.
## Issue
Transaction logs for contracts that were unknown to Embark (ie not in the dapp) would often log super large objects (filling the terminal) that were not formatted with spaces so were hard to read without actually be that useful. In addition, occasionally the object logged would throw the error `TypeError: Converting circular structure to JSON`.
## Fix
Set the log level for transaction logs that are not from a known contract to `debug`, so that they do not flood the terminal with often usused information.
Use `util.inspect` to print the transaction log instead of `JSON.stringify` to prevent circular structure errors.
The problem was that putting the artifacts in src caused them to be watched
and thus creating an infinite loop, because a change in src triggers the build of the artifacts
This was fixed by ignoring the artifacts by chokidar, wherever they are
If using `embark-snark` in the dapp as a plugin, and the dapp didn’t have any contracts, the `embark-snark` plugin would not simply exit early and essentially do nothing.
Fix `embark-snark` plugin so that it will run its routine regardless of whether or not the dapp has contracts or not.
Bump `circom` and `snarkjs` to their latest patch version.
## Issue 1 - “register” section missing
When the “register” section of `namesystem.json` was missing, ENS would not deploy the ENS contracts nor create the contracts’ artifacts.
### Fix 1
Fix ENS deployment routine to always deploy the ENS contracts. In the case of testnet/mainnet, the contracts’ addresses will be known and therefore will be understood as “already deployed” by the contract deployer.
## Issue 2 - “register” section exists for non-dev environment
Additionally, if a root domain was specified in the “register” section and the DApp connected to an external node where we do not own the ENS contracts (ie testnet), attempting to register a root domain would not be possible as we do not own the ENS contracts.
### Fix 2
Fix ENS deployment routine to check if we are on a network in which we own the ENS contracts. If we are not, and we have specified a “register” section, print a warning to the user that the registration will be ignored. Additionally, remove the “register” section.
