Stable Config parsing: Treat empty environment variable or process argument values as empty string by mtoffl01 · Pull Request #8759 · DataDog/dd-trace-java

mtoffl01 · 2025-05-02T18:12:54Z

What Does This Do

Modifies stable config file parsing logic to return "" instead of "UNDEFINED".

Motivation

While "UNDEFINED" may have been meaningful or helpful for string-based configuration values, it doesn't make sense for non-string configurations. Non-string values can't transform "UNDEFINED", so they fall back to their defaults anyway. This change simplifies the behavior by returning an empty string ("") and logging a debug message to indicate what's happening.

In an environment where DD_ENV is not set....

DD_SERVICE: {{environment_variables: ['DD_ENV']}} resolves to DD_SERVICE: "". As a result, the default service name is used
DD_SERVICE: prefix-{{environment_variables: ['DD_ENV']}}-suffix resolves to DD_SERVICE: "prefix--suffix". As a result, "prefix--suffix" is the service name
DD_PROFILING_ENABLED: {{environment_variables: ['DD_ENV']}} resolves to DD_PROFILING_ENABLED: "". As a result, the default setting (false) is used
