ocaml-trace/CHANGES.md

0.5

• perf: reduce overhead in trace-tef
• perf: add Mpsc_queue, adapted from picos, to trace-tef

0.4

• add ?data to counter_int and counter_float

• add float to user data

• add add_data_to_current_span and add_data_to_manual_span

• make explicit_span.meta mutable

• trace-tef: write to trace.json if env variable TRACE is either 1 or true

• trace-tef: emit function name, if provided, as a metadata key/value pair

• re-export trace.core in trace

• perf: in trace-tef, use broadcast instead of signal in the job queue

0.3

• add explicit spans, for more precise tracing
• rename repo to ocaml-trace
• trace-tef: add a ticker thread to ensure we flush the file regularly

0.2

• trace-tef: additional argument to with_setup; env for "stdout"/"stderr"
• refactor: avoid conflicting with stdlib Trace module by adding sublibrary trace.core. Programs that use compiler-libs.toplevel should use trace.core directly, because using trace will cause linking errors.
• perf(trace-tef): improve behavior of collector under contention by pulling all events at once in the worker
