Summary Links

madkins/replattr is the madkins/flash handler setup to test slog.HandlerOptions.ReplaceAttr performance. The madkins/flash handler is first configured to generate various warnings using flash.Extras options, then several ReplaceAttr functions are used to correct the aberrant behavior. This is intended to measure the effect of ReplaceAttr usage on performance by comparison with madkins/flash

Duplicates Duplicate field(s) found

Some handlers (e.g. slog.JSONHandler) will output multiple occurrences of the same field name if the logger is called with multiple instances of the same field, generally by using WithAttrs and then the same fields in the eventual log call (e.g. Info). This behavior is currently under debate with no resolution at this time (2024-01-15) and a release milestone of (currently unscheduled) Go 1.23, (whereas Go Release 1.22 is currently expected in February 2024).
