Package featureconfig defines which features are enabled for runtime
|
|
in order to selectively enable certain features to maintain a stable runtime.
|
|
|
|
The process for implementing new features using this package is as follows:
|
|
1. Add a new CMD flag in flags.go, and place it in the proper list(s) var for its client.
|
|
2. Add a condition for the flag in the proper Configure function(s) below.
|
|
3. Place any "new" behavior in the `if flagEnabled` statement.
|
|
4. Place any "previous" behavior in the `else` statement.
|
|
5. Ensure any tests using the new feature fail if the flag isn't enabled.
|
|
5a. Use the following to enable your flag for tests:
|
|
cfg := &featureconfig.Flags{
|
|
VerifyAttestationSigs: true,
|
|
}
|
|
resetCfg := featureconfig.InitWithReset(cfg)
|
|
defer resetCfg()
|
|
6. Add the string for the flags that should be running within E2E to E2EValidatorFlags
|
|
and E2EBeaconChainFlags.
