always enable instrumentation - Always enable OpenTelemetry instrumentation, use OTEL_EXPORT_ENABLED for data export control - Remove conditional checks from middleware, metrics, and decorators - Simplify CI configuration to use single test job instead of parallel jobs - Update tests to remove conditional logic and mocking of is_enabled() - Add comprehensive environment variable documentation to README - Update config.py to always add OpenTelemetry middleware - Replace ENABLE_OPENTELEMETRY/OTEL_ENABLED with OTEL_EXPORT_ENABLED This approach is much simpler and eliminates the complexity of conditional OpenTelemetry loading while still allowing control over data export. --- .gitlab-ci.yml | 51 ++---------- README.md | 44 ++++++++++ config.py | 3 + ivatar/opentelemetry_config.py | 103 +++++++++++------------ ivatar/opentelemetry_middleware.py | 38 +-------- ivatar/test_opentelemetry.py | 129 ++++++----------------------- 6 files changed, 128 insertions(+), 240 deletions(-) diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index 7c469bf..2556f46 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -11,56 +11,21 @@ cache: variables: PIP_CACHE_DIR: .pipcache -# Test without OpenTelemetry (baseline testing) -test_without_opentelemetry: -
