- Refactor ErrorType, list errors managment, codeError - Add interface Error with error interface implement - Add type CodeError assign typiclly to const that represent code of error - Add func to registry func to retrieve message from an uint16 codeError (typicaly a switch of each codeError const) - Add default errorCode with default errorMessage if no one code or message is found - Add modeError to manage how to manage compatibility between Error interface and error interface - Add Error interface that allow parent link (parent as error or Error interface), code and trace management - Add trace finder to allow find func/file/line caller when Error is call - Add http 2 transport in httpcli - Add http 2 transport in httpserver - Add function to get client http with timeout management in httpcli - Add function to get Error if occurs of http client in httpcli - Add test for smtp package - Chg return error by returning Error in all packages - Chg package njs-archive by archive - Chg package njs-certif by certificates - Chg package njs-console by console - Chg package njs-crypt by crypt - Chg package njs-errors by errors - Chg package njs-httpcli by httpcli - Chg package njs-httpserver by httpserver - Chg package njs-ioutils by ioutils - Chg package njs-ldap by ldap - Chg package njs-logger by logger - Chg package njs-password by password - Chg package njs-progress by progress - Chg package njs-router by router - Chg package njs-semaphore by semaphore - Chg package njs-smtp by smtp - Chg package njs-static by static - Chg package njs-status by status - Chg package njs-version by version - Fix dependancies gopkg by github/go-ldap for go module compatibility - Fix gin Abort call by gin Abort with Error in static package - Fix issue #18 in status package : replace partner by component - Fix go vet error - Del deprecated function - Del useless function & files - Bump dependancies - Apply CHG in README.md
