Description
When calling
resolveVAccelConfig()inpkg/unikontainers/unikontainers.go, we only print the error at DEBUG level. The function returns the same error type in 2 different cases:1) when vAccel is disabled and
2) when a bad configuration is detected (i.e. missing or bad RPCAddress).
Therefore the error is always ignored and the container launched in with no vAccel but with no warning of the situation.
The fix adds a sentinel error
ErrVAccelDisabledto treat the two cases differently. When vAccel is not configured, we expect an error and log it at Debug. When there is a genuine misconfiguration, we Warn so operators can see theissue without having to enable debug log level. Added unit tests for all four paths in
resolveVAccelConfig.Files changed:
