Simon Cruanes	151d80d0f1	breaking: feat(trace): pass a string trace_id in manual spans ... - in entering manual spans, we now pass an explicit span_ctx that contains a trace_id (bytes) and the parent span id (int64). - this makes compat with OTEL easier as we want this sort of span_ctx to be passed around.	2025-04-09 09:28:09 -04:00

Simon Cruanes	0b6dc27556	break tef: use mtime.now, not a counter, for multiproc ... this allows us to correlate timestamps among processes on the same machine.	2024-08-23 15:17:55 -04:00

Simon Cruanes	c16666d214	perf: reduce overhead in trace-tef ... we call onto the channel functions less, because they involve locking. Instead we do all writes into a (reused) buffer and write it all at once at the end.	2023-12-05 14:52:40 -05:00
Simon Cruanes	0e198c8059	compat < 5.0	2023-11-28 14:31:16 -05:00

Simon Cruanes	4fc81d4ca2	tef: carry additional data for manual spans in the explicit_span's map ... the span opening has been emitted already, so we'll emit the metadata at exit time. We don't need side storage since we already have a hmap.	2023-08-30 20:24:17 -04:00

Simon Cruanes	96fb44e6bb	trace-tef: emit function name, if provided, as a metadata key/value pair ... the key is "function". It is visible when selecting the span, typically.	2023-08-19 17:13:56 -04:00
Simon Cruanes	0eb6a84982	feat: add ?flavor argument to manual spans.	2023-08-09 00:26:21 -04:00
