package opentelemetry-client-cohttp-lwt

0.10

• feat: add support for per-signal urls (by @tatchi)

• fix: emit GC metrics even in the absence of custom metrics

0.9

• compat with trace 0.7

0.8

• feat: add dep on hmap, add standard keys to carry around a span context or trace id

• add semantic conventions for code and HTTP

0.7

• add Span_link.of_span_ctx, Scope.to_span_ctx, dummy values

• feat: add Span_context, as required by OTEL API guidelines

• feat: record backtraces in error spans

• compat with trace 0.6

• ocurl: add ticker_interval_ms config

• ocurl: do some self-tracing optionally

• move protobuf code to opentelemetry.proto

• perf: rewrite parsing+printing for span ctx as w3c trace ctx

• perf: when we get multiple messages, check batches only once

• perf: use ocaml-protoc 3.0.1 for codegen, with faster pbrt

0.6

• fix ticker thread shutdown

• migrated to OTEL proto files v1.0

• replace Thread_local with ocaml-ambient-context, allowing for implicit scope in Lwt/Eio contexts (#34)

• update ocaml-trace interface to use the new trace.0.3-style API (breaking, see #34)

0.5

• new implementation for ocurl backend, using ezcurl and queues

• refactor lwt: Use try%lwt over Lwt.catch

• add opentelemetry.trace (optional, depends on ocaml-trace)

0.4

• expose Scope.get_surrounding

• rehault of GC metrics

• Trace.with_ now has force_new_trace_id param

• use thread-local storage to store global scope

• add Span_link module

• add a Globals.default_span_kind ref to specify default span kind

• fix(otel-lwt): missing modules now re-exported

• fix(client-ocurl): fix tick version used in the absence of bg thread

• drop dep on ocaml-protoc as the generated code is checked-in

• update vendored otel to 0.19

0.3

• improve error reporting from ocurl exporter

• improve GC sample collection

• feat(ocurl): simpler, cleaner backend implementation, with graceful exit

• config: make Config.t private (breaking)

0.2

• require pbrt only, use ocaml-protoc as a lint

• add Metrics_callbacks module

• add histogram metrics (untested)

• basic support for logs

• expose tick function (useful in the absence of a background thread)

• debug the library is set via OTEL_OCAML_DEBUG

• provide conventions for standard metrics

• add runtime attrs to GC stats
