mara: comments to code ratio too high. It was 16 comment lines for one
line of feature.
Kept only the fact that stops the feature being trimmed away again - it
is not a transport, it is in `default`, so `default-features = false`
drops it - and, in hive-metric, the one reason its declaration
deliberately differs. Why an HTTP 200 is the failure that matters, and
what a stderr-reporting CLI would cost, are the PR's and the follow-up
issue's job, not the manifest's.
`default-features = false` on opentelemetry-otlp was written to trim
transports and dropped `internal-logs` with them, so every otel_warn! and
otel_debug! inside that crate compiled to nothing. The failure that
matters is the one which returns HTTP 200: the collector accepts the
request and rejects the data points, and HttpMetricsClient.PartialSuccess
is the only place the rejection count and the collector's reason are ever
surfaced.
The feature is per-crate, not per-workspace: the macros are exported by
the opentelemetry API crate but their cfg and CARGO_PKG_NAME resolve in
the calling crate, so the API crate and the SDK had internal logs on
while the exporter did not.
hive-metric keeps the identical declaration on purpose - it installs no
tracing subscriber, so the feature would be inert there and would only
mislead. Both files now record which side of that they are on, and the
stale "same features as hive-metric" comment is corrected.
Not sufficient on its own: a hard export failure is logged by the SDK at
debug on the compiled timer path, so it stays below the info filter.
That needs a level rather than a feature and is left to review.
Second increment of the per-crate README effort, covering the rest of the
infra/wire/priv column: hive-priv, hive-metric, hive-types, hive-sh4re,
hive-core-agent-sock, hive-agent-sock. Same shape as the first batch —
purpose + when-to-use, and point at the crate-root //! docs plus the
relevant docs/ pages rather than duplicating them. Wires
readme = "README.md" into each Cargo.toml [package].
Disjoint from the batch-1 crates, so the two increments compose cleanly.
