Compliance Matrix Validation for rel1.0.0 -Context Propagation

[lalitb]

This ticket is to validate the below attributes of Spec Compliance Matrix for Rel 1.0.0. While validation, if there is any ticket created for non-compliance, mention that next to the non-compliant point below in the description.

Context Propagation:

• Create Context Key
• Get value from Context
• Set value for Context
• Attach Context
• Detach Context
• Get current Context
• Composite Propagator
• Global Propagator
• TraceContext Propagator
• B3 Propagator
• Jaeger Propagator

TextMap Propagator:

• Fields (API to fetch propagation fields set by TextMapPropagator::Inject() method #762)
• Setter argument
• Getter argument
• Getter argument returning Keys (API to fetch propagation fields set by TextMapPropagator::Inject() method #762)

Context Propagation:

Create Context Key

This is not configurable. The default keys are hard-coded in code - current_span, baggage.

Get value from Context

opentelemetry-cpp/api/include/opentelemetry/context/runtime_context.h

Line 122 in b4584ad

static ContextValue GetValue(nostd::string_view key, Context *context = nullptr) noexcept

Set value for Context

opentelemetry-cpp/api/include/opentelemetry/context/runtime_context.h

Lines 102 to 105 in b4584ad

	static Context SetValue(nostd::string_view key,
	const ContextValue &value,
	Context *context = nullptr) noexcept
	{

Attach Context

opentelemetry-cpp/api/include/opentelemetry/context/runtime_context.h

Line 87 in b0f27a4

static nostd::unique_ptr<Token> Attach(const Context &context) noexcept

Detach Context

opentelemetry-cpp/api/include/opentelemetry/context/runtime_context.h

Line 94 in b0f27a4

static bool Detach(Token &token) noexcept { return GetRuntimeContextStorage()->Detach(token); }

Get current Context

opentelemetry-cpp/api/include/opentelemetry/context/runtime_context.h

Line 83 in b0f27a4

static Context GetCurrent() noexcept { return GetRuntimeContextStorage()->GetCurrent(); }

Composite Propagator

Global Propagator

https://github.com/open-telemetry/opentelemetry-cpp/blob/v0.6.0/api/include/opentelemetry/context/propagation/global_propagator.h

TraceContext Propagator

https://github.com/open-telemetry/opentelemetry-cpp/blob/v0.6.0/api/include/opentelemetry/trace/propagation/http_trace_context.h

B3 Propagator

https://github.com/open-telemetry/opentelemetry-cpp/blob/v0.6.0/api/include/opentelemetry/trace/propagation/b3_propagator.h
