Overview ¶
Package kernel provides functions to read kernel parameters from the system.
Index ¶

DefaultCmdlinePath is the default path to the kernel command line.

Types ¶
type Interface ¶
type Interface interface {
// ReadParameters reads and returns kernel parameters from the system.
ReadParameters() (*Parameters, error)
}
Interface provides an interface for reading kernel parameters.
type InterfaceMock ¶
type InterfaceMock struct {
// ReadParametersFunc mocks the ReadParameters method.
ReadParametersFunc func() (*Parameters, error)
// contains filtered or unexported fields
}
InterfaceMock is a mock implementation of Interface.
func TestSomethingThatUsesInterface(t *testing.T) {
// make and configure a mocked Interface
mockedInterface := &InterfaceMock{
ReadParametersFunc: func() (*Parameters, error) {
panic("mock out the ReadParameters method")
},
}
// use mockedInterface in code that requires Interface
// and then make assertions.
}
func (*InterfaceMock) ReadParameters ¶
func (mock *InterfaceMock) ReadParameters() (*Parameters, error)
ReadParameters calls ReadParametersFunc.
func (*InterfaceMock) ReadParametersCalls ¶
func (mock *InterfaceMock) ReadParametersCalls() []struct { }
ReadParametersCalls gets all the calls that were made to ReadParameters. Check the length with:
len(mockedInterface.ReadParametersCalls())
type Parameters ¶
type Parameters struct {
// CommandLine contains the raw kernel boot parameters from /proc/cmdline.
CommandLine string
}
Parameters holds kernel boot parameters.
type SystemReader ¶
type SystemReader struct {
// contains filtered or unexported fields
}
SystemReader reads kernel parameters from the actual system files.
func NewSystemReader ¶
func NewSystemReader() *SystemReader
NewSystemReader creates a new SystemReader with the default cmdline path.
func NewSystemReaderWithPath ¶
func NewSystemReaderWithPath(cmdlinePath string) *SystemReader
NewSystemReaderWithPath creates a new SystemReader with a custom cmdline path. This is useful for testing.
func (*SystemReader) ReadParameters ¶
func (r *SystemReader) ReadParameters() (*Parameters, error)
ReadParameters reads kernel parameters from /proc/cmdline and returns them as a Parameters struct with the raw command line content.
