Package Monitoring : - use packag dedicated to monitor component - each monitor work as standalone server to monitor health - collect metrics to export them to prometheus exporter Package Prometheus : - review to simplify use for API and not API metrics - optimize code Package Status : - Rework to use Monitor package - Rework to use native json / text Marshaller interface Context : - rework context config (context var) to use sync map and sync RWMutex (WORM) - move gin context to dedicated sub package (dependancies of logger make circular dependencies) - optimize code Config : - rework to optimize sync / collect of component - rework status to monitor - remove monitor managment from config to each component - add a func to set default logger to implement inherit default logger options - optimize code IOUtils : - isolate logger / closer interface as a usable & public interface & instance - this interface / instance allow to collect io.closer over a context to close all if context is done Logger : - rework to use context.config map - rework to use ioutils closer - rework to allow options to inherit a default options, or the last version of options - optimize code Size : - Add package Size to calculate and manipulate size Byte or bit - Add encoding : Text/JSON/Yaml/Toml... - Add option to défine default unit : Byte or bit Other : - adjust following code - optimize code - limit use of atomic value - rework to use RWMutex instead of sync.Mutex to maximize capabilities of read instead of write - remove 32bit build for CI/CD - add darwin/arm64 build for CI/CD Bump Dependencies
