End-user changelog

🛑 Breaking changes 🛑

• cmd/mdatagen: Generated processor lifecycle tests now assert that the processor propagates the incoming context unchanged to the next consumer by default. (#15994)
  Disable with skip_context_propagation: true

• processor/queue_batch: Rename queuebatch processor to queue_batch processor. (#14396)

💡 Enhancements 💡

• extension/memory_limiter: Add otelcol_memorylimiter_refused_requests metric to record network request refusals in extension mode. (#15561)

• pkg/confighttp: Enable keepalive configuration by default. (#16026)
  Introduces the feature gate pkg.confighttp.PrioritizeNewKeepalive. When disabled, this flag
  restores the old behaviour of removing the keepalive configuration in favour
  of the deprecated fields IdleConnTimeout, MaxIdleConns, MaxIdleConnsPerHost,
  DisableKeepAlives when the flag is disabled.

• pkg/exporterhelper: Make the partition idle timeout configurable via batch::partition::idle_timeout and raise the default to 90s. (#15894)

• pkg/exporterhelper: Make the multi-batcher partition LRU cache size configurable and export cache size metrics. (#14526)
  Adds sending_queue::batch::partition::cache_size (default 10000) to cap the
  number of active partition batchers. The value
  must be positive. Current size and configured capacity are exported as
  otelcol_exporter_queue_batch_partition_cache_size
  and otelcol_exporter_queue_batch_partition_cache_capacity.

• pkg/pprofile: Speed up profiles dictionary merging during exporter-queue batching by replacing the linear-scan dedup in switchDictionary with an indexed lookup, reducing per-merge cost from O(N*L^2) to O(N+L). (#15544)
  No behavior change: merged dictionary contents and remapped indices are identical to before.

• pkg/receiverhelper: Stop allocating a span link that is always discarded when a long-lived-context receiver starts an operation without a parent span context. (#15998)
  Receivers created with LongLivedCtx: true no longer build a trace.Link when the
  long-lived context carries no valid span context. The SDK already discarded such a link,
  so behaviour is unchanged. This removes 3 of 7 allocations per receive operation.

• pkg/xpdata: Reduce the time xhash.MapHash takes for maps with many entries. (#15990)

🧰 Bug fixes 🧰

• exporter/debug: Support known sync error handling on AIX (#15924)
  Enable the debug exporter to handle known synchronous errors on AIX.

• pkg/exporterhelper: Drop only the oversized item when splitting a batch, instead of discarding every item queued behind it (#15936)
  Applied to logs only for now

• pkg/exporterhelper: Add exporter and data_type attributes to exporter/enqueue spans. (#16022)

• receiver/otlp: Error handler preserves the HTTP status code when the request Content-Type is not one a Status can be encoded in (#15995)
  Extends the fix in #13414, which handled a missing Content-Type. A Content-Type that was
  present but unsupported, or malformed, still fell through to
  500 {"code": 13, "message": "failed to marshal error message"}, reporting client errors
  such as 401 from a server auth extension or 400 from an unsupported Content-Encoding as
  server faults.

v1.67.0/v0.161.0

🛑 Breaking changes 🛑

• pkg/pprofile: Remove deprecated AggregationTemporality, Duration, SetDuration (#15855)
• pkg/scraperhelper/controller: Remove deprecated AddScraper func (#15934)
• pkg/service: Remove deprecated ZapOptions (#15935)
• pkg/xconfmap: Remove deprecated WithForceUnmarshaler func (#15932)

💡 Enhancements 💡

• pkg/pdata: avoid allocations in WriteInt64 and WriteUint64 (#15629)

🧰 Bug fixes 🧰

• cmd/schemagen: Accept components written without a configuration body in the generated Collector configuration schema (#15728)

• pkg/confmap: Fix bug where an escaped URI appearing before a valid URI prevented the subsequent URI from being expanded. (#15867)
  URI scanning now continues after an escaped URI while preserving the escaped expression as literal text.

• pkg/featuregate: Reject feature gate IDs with an empty dot-separated segment (leading, trailing, or consecutive dots), e.g. .foo, foo., foo..bar. (#15676)

• pkg/pprofile: Stop erasing inline attribute keys when key_strindex is unset, and clear key_strindex once it is resolved. (#15793)

• pkg/pprofile: Reference resource and scope attribute strings via the ProfilesDictionary string table when marshaling and unmarshaling OTLP profiles export requests. (#15792)

• pkg/scraperhelper: Fix shutdown being delayed by extra scrapes when a scrape runs longer than the collection interval (#15736)
  If a scrape was still running when the next tick fired, the pending tick and the shutdown
  signal could both be ready when it finished and the controller chose between them at random.

API changelog

💡 Enhancements 💡

• cmd/mdatagen: Allow config metadata authors to choose configoptional.Some or configoptional.Default for generated optional fields (#15977)
  Set go_struct.optional_mode: default to generate an optional object configuration
  section with a fallback default while keeping it absent until configured. Omitting
  optional_mode preserves the existing configoptional.Some behavior.

• pkg/config/configgrpc: Migrate core types of common settings for a gRPC client to schema-based configuration generated by mdatagen. (#15967)

• pkg/exporterhelper: Add NewDefaultBatchConfig to build a BatchConfig with default values, including the partition cache_size and idle_timeout defaults. (#14526, #15894)

• pkg/exporterhelper: Make the partition idle timeout configurable via batch::partition::idle_timeout and raise the default to 90s. (#15894)

• pkg/exporterhelper: Make the multi-batcher partition LRU cache size configurable and export cache size metrics. (#14526)
  Adds sending_queue::batch::partition::cache_size (default 10000) to cap the
  number of active partition batchers. The value
  must be positive. Current size and configured capacity are exported as
  otelcol_exporter_queue_batch_partition_cache_size
  and otelcol_exporter_queue_batch_partition_cache_capacity.

• pkg/xpdata: Move pdata hash APIs from the contrib repo (#15914)

🧰 Bug fixes 🧰

• cmd/schemagen: Fix RefResolver mutating shared, cached type definitions with per-occurrence annotations, which caused generated schemas to have incorrect (and run-to-run nondeterministic) description/x-optional/x-pointer values whenever multiple fields referenced the same type. (#15984)
• pkg/pdata: Fix pcommon.Value.CopyTo to deep-copy ValueTypeBytes values instead of sharing the backing array (#15621)
  The bytes oneof field in CopyAnyValue was assigned directly, so the copy and source shared the same []byte.
  This also affected Map.CopyTo and Slice.CopyTo, which delegate to CopyAnyValue.
