go.internal.godebug

C# package converted from the Go standard library by go2cs. Go version: 1.23.1

Tests

Package godebug makes the settings in the $GODEBUG environment variable available to other packages. These settings are often used for compatibility tweaks, when we need to change a default behavior but want to let users opt back in to the original. For example GODEBUG=http2server=0 disables HTTP/2 support in the net/http server.

In typical usage, code should declare a Setting as a global and then call Value each time the current setting value is needed:

var http2server = godebug.New("http2server")

func ServeConn(c net.Conn) {
	if http2server.Value() == "0" {
		disallow HTTP/2
		...
	}
	...
}

Each time a non-default setting causes a change in program behavior, code must call [Setting.IncNonDefault] to increment a counter that can be reported by runtime/metrics.Read. The call must only happen when the program executes a non-default behavior, not just when the setting is set to a non-default value. This is occasionally (but very rarely) infeasible, in which case the internal/godebugs table entry must set Opaque: true, and the documentation in doc/godebug.md should mention that metrics are unavailable.

Conventionally, the global variable representing a godebug is named for the godebug itself, with no case changes:

var gotypesalias = godebug.New("gotypesalias") // this
var goTypesAlias = godebug.New("gotypesalias") // NOT THIS

The test in internal/godebugs that checks for use of IncNonDefault requires the use of this convention.

Note that counters used with IncNonDefault must be added to various tables in other packages. See the [Setting.IncNonDefault] documentation for details.
