### Changed

- ⚠️ **Breaking Change:** `go.opentelemetry.io/otel/sdk/metric` now
applies a default cardinality limit of 2000 to comply with the Metrics
SDK specification recommendation.
New attribute sets are dropped when the cardinality limit is reached.
The measurement of these sets are aggregated into a special attribute
set containing `attribute.Bool("otel.metric.overflow", true)`.
  This can break users who relied on the previous unlimited default.
Set `WithCardinalityLimit(0)` or the deprecated
`OTEL_GO_X_CARDINALITY_LIMIT=0` environment variable to preserve
unlimited cardinality.
Note that support for `OTEL_GO_X_CARDINALITY_LIMIT` may be removed in a
future release. (#8247)
- `ErrorType` in `go.opentelemetry.io/otel/semconv` now unwraps errors
created with `fmt.Errorf` when deriving the `error.type` attribute.
(#8133)
- `go.opentelemetry.io/otel/sdk/log` now unwraps error chains created
with `fmt.Errorf` when deriving the `error.type` attribute from errors
on log records. (#8133)
- `Set.MarshalLog` method in `go.opentelemetry.io/otel/attribute` now
uses `Value.String` formatting following the [OpenTelemetry AnyValue
representation for non-OTLP
protocols](https://opentelemetry.io/docs/specs/otel/common/#anyvalue).
(#8169)
- Optimize `go.opentelemetry.io/otel/sdk/metric` to return a drop
reservoir and short-circuit `Offer` calls to the exemplar reservoir when
`exemplar.AlwaysOffFilter` is configured. (#8211) (#8267)
- Optimize `go.opentelemetry.io/otel/sdk/metric` to return a drop
reservoir for asynchronous instruments when `exemplar.TraceBasedFilter`
is configured. (#8286)

### Deprecated

- Deprecate `Value.Emit` method in `go.opentelemetry.io/otel/attribute`.
  Use `Value.String` instead. (#8176)

### Fixed

- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Fix gzipped request body replay on redirect in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#8135)
- Fix gzipped request body replay on redirect in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8152)
- `go.opentelemetry.io/otel/exporters/prometheus` now uses
`Value.String` formatting for label values following the [OpenTelemetry
AnyValue representation for non-OTLP
protocols](https://opentelemetry.io/docs/specs/otel/common/#anyvalue).
(#8170)
- Propagate errors from the exporter when calling `Shutdown` on
`BatchSpanProcessor` in `go.opentelemetry.io/otel/sdk/trace`. (#8197)
- Fix stale status code reporting on self-observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` and
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8226)
- Fix a concurrent `Collect` data race and potential panic in
`go.opentelemetry.io/otel/exporters/prometheus` when
`WithResourceAsConstantLabels` option is used. (#8227)
- Fix race condition in `FixedSizeReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar` by reverting #7447.
(#8249)
- Fix `FixedSizeReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar` to safely handle zero
size.
A capacity check in the constructor initializes the reservoir safely and
skips initialization for zero-cap; early returns in `Offer()` and
`Collect()` ensure no-op behavior. (#8295)
- Fix counting of spans and logs in self-observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`,
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`,
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`, and
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8254)
- Drop conflicting scope attributes named `name`, `version`, or
`schema_url` from metric labels in
`go.opentelemetry.io/otel/exporters/prometheus`, preserving the
dedicated `otel_scope_name`, `otel_scope_version`, and
`otel_scope_schema_url` labels. (#8264)
- Close schema files opened by `ParseFile` in
`go.opentelemetry.io/otel/schema/v1.0` and
`go.opentelemetry.io/otel/schema/v1.1`.
([GHSA-995v-fvrw-c78m](https://github.com/open-telemetry/opentelemetry-go/security/advisories/GHSA-995v-fvrw-c78m))
- Enforce the 8192-byte baggage size limit during extraction/parsing,
changing behavior when the limit is exceeded in
`go.opentelemetry.io/otel/baggage` and
`go.opentelemetry.io/otel/propagation`. (#8222)
- Fix `go.opentelemetry.io/otel/semconv/v1.41.0` to include `Attr*`
helper methods for required attributes on observable instruments.
(#8361)
- Limit baggage extraction error reporting in
`go.opentelemetry.io/otel/propagation` to prevent malformed or oversized
baggage headers from flooding logs.

### Release Notes

<details>
<summary>mvdan/gofumpt (mvdan.cc/gofumpt)</summary>

###
[`v0.10.0`](https://redirect.github.com/mvdan/gofumpt/blob/HEAD/CHANGELOG.md#v0100---2026-05-04)

[Compare
Source](https://redirect.github.com/mvdan/gofumpt/compare/v0.9.2...v0.10.0)

This release is based on Go 1.26's gofmt, and requires Go 1.25 or later.

A new rule is introduced to drop unnecessary parentheses around
expressions
where the inner expression is unambiguous on its own, such as `f((3))`.
Parentheses are kept where they are useful, such as on binary
expressions. See
[#&#8203;44](https://redirect.github.com/mvdan/gofumpt/issues/44).

A new rule is introduced to require multi-line function calls to match
the opening and closing parenthesis in terms of the use of newlines. See
[#&#8203;74](https://redirect.github.com/mvdan/gofumpt/issues/74).

The `-extra` flag now accepts a comma-separated list of rule names to
enable
individual extra rules, rather than enabling all of them at once. See
[#&#8203;339](https://redirect.github.com/mvdan/gofumpt/issues/339).

The following changes are included as well:

- Avoid crashing on `go.mod` files without a `module` directive -
[#&#8203;350](https://redirect.github.com/mvdan/gofumpt/issues/350)
- Avoid failing when an ignored directory cannot be read -
[#&#8203;351](https://redirect.github.com/mvdan/gofumpt/issues/351)
- Avoid prefixing more kinds of commented-out Go code with spaces -
[#&#8203;230](https://redirect.github.com/mvdan/gofumpt/issues/230)
- Avoid prefixing a shebang comment with a space -
[#&#8203;237](https://redirect.github.com/mvdan/gofumpt/issues/237)
- Narrow the newlines on assignments rule to ignore complex cases -
[#&#8203;354](https://redirect.github.com/mvdan/gofumpt/issues/354)
- Fix three bugs which caused a second gofumpt run to make changes -
[#&#8203;132](https://redirect.github.com/mvdan/gofumpt/issues/132),
[#&#8203;345](https://redirect.github.com/mvdan/gofumpt/issues/345)

Ali Asghar c5045485b4 metric: clarify sync vs observable Gauge in package godoc (#8225) 
## Description

The "Measurements" description in the
\`go.opentelemetry.io/otel/metric\` package godoc stated that a Gauge is
used when "the most recent measurement needs to be conveyed about an
asynchronous measurement" and only listed \`Int64ObservableGauge\` and
\`Float64ObservableGauge\`. Synchronous Gauge types (\`Int64Gauge\`,
\`Float64Gauge\`) were added to the API but are not reflected in this
paragraph.

This PR updates the sentence to list all four Gauge types and briefly
note the difference (sync records an instantaneous value at a specific
point in code; observable samples via a callback once per collection
cycle).

Partially addresses #4801 (the "explain the differences between
instrument types" request) by correcting the Gauge coverage
specifically. Happy to follow up with a broader summary-by-example list
if @pellared thinks that's still valuable.

Fixes #4801.

## Checklist

- [x] CHANGELOG.md entry added (placeholder `#XXXX`, will update with
real PR number once assigned).
- [ ] Tests updated (godoc-only change, no behavior change).

David Ashpole 48dd8b1a09 Add x.Settable to allow reusing attribute options (#8178) 
Fixes https://github.com/open-telemetry/opentelemetry-go/issues/7851

This adopts this proposal from @MrAlias:
https://github.com/open-telemetry/opentelemetry-go/issues/7851#issuecomment-3837399805

This adds a Set function to attrOpt, and changes attrOpt functions to
use a pointer receiver. Users can use this by checking if the attribute
option implements the `Settable` interface in `metric/x`. There are no
public API changes to the metric package, as this is still an
experiment. See the benchmark change and the interface documentation for
how it can be used to avoid calling metric.WithAttributeSet.

I updated the benchmark in
https://github.com/open-telemetry/opentelemetry-go/commit/448394b549375f4f6742201e199e0339d0b78524,
but didn't commit it here to avoid a dependency between the SDK and the
`metric/x` package.

As expected, this removes one allocation from the Dynamic case!

The results are:

David Ashpole d96b420138 Add support for the development attributes advisory parameter (#8135) 
From [the
spec](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/api.md#instrument-advisory-parameter-attributes):

> ##### Instrument advisory parameter: `Attributes`

> **Status**: [Development](../document-status.md)

> Applies to all instrument types.

> `Attributes` (a list of [attribute
keys](../common/README.md#attribute)) is
the recommended set of attribute keys to be used for the resulting
metrics.

We already have `WithAttributes` options, so i've opted to name this
`WithDefaultAttributes` to avoid naming collisions. We could also
consider `WithAttributeKeys`, or `WithDefaultAttributeKeys`

Follows the pattern for experimental options introduced in
https://github.com/open-telemetry/opentelemetry-go/pull/8111

David Ashpole 28df982c8b Add support for experimental options in the metrics API (#8111) 
Part of https://github.com/open-telemetry/opentelemetry-go/issues/8110

Related to
https://github.com/open-telemetry/opentelemetry-go/issues/5882.

I'm hoping to find a better way to support experimental Options types in
our API packages. This is one approach to consider.

This contains no public API changes. It introduces a type:
`ExperimentalOption` in `/metric/internal/x`, which can be used by our
experimental options defined outside of the module. Options that embed
this interface are ignored by `New*Config` builder functions in the
metrics API to prevent them from panicing when used. Only SDKs that
explicitly support the experimental option in question will respect it.
Alternative SDKs will ignore the experimental options. We would still
need to treat ExperimentalOption as a stable artifact, since the SDK
will indirectly depend on it.

See
https://github.com/open-telemetry/opentelemetry-go/compare/main...dashpole:opentelemetry-go:attributes_advisory
for how this would be used to support the advisory attributes parameter.

Damien Mathieu 9276201a64 Release v1.43.0 / v0.65.0 / v0.19.0 (#8128) 
Release issue:
https://github.com/open-telemetry/opentelemetry-go/issues/8127

## Added

- Add `IsRandom` and `WithRandom` on `TraceFlags`, and `IsRandom` on
`SpanContext` in `go.opentelemetry.io/otel/trace`

Flag](https://www.w3.org/TR/trace-context-2/#random-trace-id-flag)
support. (#8012)
- Add service detection with `WithService` in
`go.opentelemetry.io/otel/sdk/resource`. (#7642)

`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
(#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`.
(#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest`. (#8038)
- Add support for per-series start time tracking for cumulative metrics
in `go.opentelemetry.io/otel/sdk/metric`.
  Set `OTEL_GO_X_PER_SERIES_START_TIMESTAMPS=true` to enable. (#8060)
- Add `WithCardinalityLimitSelector` for metric reader for configuring
cardinality limits specific to the instrument kind. (#7855)

## Changed

- Introduce the `EMPTY` Type in `go.opentelemetry.io/otel/attribute` to
reflect that an empty value is now a valid value, with `INVALID`
remaining as a deprecated alias of `EMPTY`. (#8038)
- Refactor slice handling in `go.opentelemetry.io/otel/attribute` to
optimize short slice values with fixed-size fast paths. (#8039)
- Improve performance of span metric recording in
`go.opentelemetry.io/otel/sdk/trace` by returning early if
self-observability is not enabled. (#8067)
- Improve formatting of metric data diffs in
`go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest`. (#8073)

## Deprecated

- Deprecate `INVALID` in `go.opentelemetry.io/otel/attribute`. Use
`EMPTY` instead. (#8038)

## Fixed

- Return spec-compliant `TraceIdRatioBased` description. This is a
breaking behavioral change, but it is necessary to
make the implementation
[spec-compliant](https://opentelemetry.io/docs/specs/otel/trace/sdk/#traceidratiobased).
(#8027)
- Fix a race condition in `go.opentelemetry.io/otel/sdk/metric` where
the lastvalue aggregation could collect the value 0 even when no
zero-value measurements were recorded. (#8056)
- Limit HTTP response body to 4 MiB in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` to
mitigate excessive memory usage caused by a misconfigured or malicious
server.
Responses exceeding the limit are treated as non-retryable errors.
(#8108)
- Limit HTTP response body to 4 MiB in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` to
mitigate excessive memory usage caused by a misconfigured or malicious
server.
Responses exceeding the limit are treated as non-retryable errors.
(#8108)
- Limit HTTP response body to 4 MiB in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp` to
mitigate excessive memory usage caused by a misconfigured or malicious
server.
Responses exceeding the limit are treated as non-retryable errors.
(#8108)
- `WithHostID` detector in `go.opentelemetry.io/otel/sdk/resource` to
use full path for `kenv` command on BSD. (#8113)
- Fix missing `request.GetBody` in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp` to
correctly handle HTTP2 GOAWAY frame. (#8096)

Tyler Yahn a3a5317c5c Release v1.40.0 (#7859) 
### Added

- Add `Enabled` method to all synchronous instrument interfaces
(`Float64Counter`, `Float64UpDownCounter`, `Float64Histogram`,
`Float64Gauge`, `Int64Counter`, `Int64UpDownCounter`, `Int64Histogram`,
`Int64Gauge`,) in `go.opentelemetry.io/otel/metric`. This stabilizes the
synchronous instrument enabled feature, allowing users to check if an
instrument will process measurements before performing computationally
expensive operations. (#7763)
- Add `AlwaysRecord` sampler in `go.opentelemetry.io/otel/sdk/trace`.
(#7724)
- Add `go.opentelemetry.io/otel/semconv/v1.39.0` package. The package
contains semantic conventions from the `v1.39.0` version of the
OpenTelemetry Semantic Conventions. See the [migration
documentation](https://github.com/open-telemetry/opentelemetry-go/blob/298cbedf256b7a9ab3c21e41fc5e3e6d6e4e94aa/semconv/v1.39.0/MIGRATION.md)
for information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.38.0.` (#7783, #7789)

### Changed

- `Exporter` in `go.opentelemetry.io/otel/exporter/prometheus` ignores
metrics with the scope `go.opentelemetry.io/contrib/bridges/prometheus`.
This prevents scrape failures when the Prometheus exporter is
misconfigured to get data from the Prometheus bridge. (#7688)
- Improve performance of concurrent histogram measurements in
`go.opentelemetry.io/otel/sdk/metric`. (#7474)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/stdout/stdoutmetric`. (#7492)
- Improve the concurrent performance of `HistogramReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar` by 4x. (#7443)
- Improve performance of concurrent synchronous gauge measurements in
`go.opentelemetry.io/otel/sdk/metric`. (#7478)
- Improve performance of concurrent exponential histogram measurements
in `go.opentelemetry.io/otel/sdk/metric`. (#7702)
- Improve the concurrent performance of `FixedSizeReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar`. (#7447)
- The `rpc.grpc.status_code` attribute in the experimental metrics
emitted from
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` is
replaced with the `rpc.response.status_code` attribute to align with the
semantic conventions. (#7854)
- The `rpc.grpc.status_code` attribute in the experimental metrics
emitted from
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc` is
replaced with the `rpc.response.status_code` attribute to align with the
semantic conventions. (#7854)

### Fixed

- Fix bad log message when key-value pairs are dropped because of key
duplication in `go.opentelemetry.io/otel/sdk/log`. (#7662)
- Fix `DroppedAttributes` on `Record` in
`go.opentelemetry.io/otel/sdk/log` to not count the non-attribute
key-value pairs dropped because of key duplication. (#7662)
- Fix `SetAttributes` on `Record` in `go.opentelemetry.io/otel/sdk/log`
to not log that attributes are dropped when they are actually not
dropped. (#7662)
- `WithHostID` detector in `go.opentelemetry.io/otel/sdk/resource` to
use full path for `ioreg` command on Darwin (macOS). (#7818)
- Fix missing `request.GetBody` in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` to
correctly handle HTTP2 GOAWAY frame. (#7794)

Antoine Gagniere 570bcc37ae Explicitly discourage the use of mutexes inside callbacks (#7792) 
The
[specifications](https://opentelemetry.io/docs/specs/otel/metrics/api/#asynchronous-instrument-api)
about callbacks say:

> Callback functions MUST be documented as follows for the end user:
> - **Callback functions SHOULD be reentrant safe.** The SDK expects to
evaluate callbacks for each MetricReader independently.
> - **Callback functions SHOULD NOT take an indefinite amount of time.**
> - Callback functions SHOULD NOT make duplicate observations (more than
one Measurement with the same attributes) across all registered
callbacks.
>
> The resulting behavior when a callback violates any of these
RECOMMENDATIONS is explicitly not specified at the API level.

Currently the Go API mentions that callbacks "needs to complete in a
finite amount of time" and "needs to be concurrent safe", but does not
mention reentrancy.

And while close in meaning, there is a nuance between reentrant and
concurrent safe, and a function locking a plain (non-recursive) mutex is
an example of a function that is concurrent safe while not being
reentrant.

Furthermore, in the Go implementation provided in this repo, the metrics
pipeline locks a mutex (in `produce`) then calls all callbacks, which
means that locking a mutex from within a callback would mean holding 2
mutexes at the same time, which opens the door to a deadlock.

In conclusion, users should be made aware in no uncertain terms that
locking a mutex from callbacks is discouraged and not a supported
behavior

(Relates to the discussion in #7755)

Robert Pająk 7706e21e4a metric: add Enabled method to synchronous instruments (#7763) 
Fixes https://github.com/open-telemetry/opentelemetry-go/issues/7681
 2026-01-12 16:21:49 +01:00
Tyler Yahn 6ce14298b9 Release v1.39.0 (#7676) 
## Overview

### Added

- Greatly reduce the cost of recording metrics in
`go.opentelemetry.io/otel/sdk/metric` using hashing for map keys.
(#7175)
- Add `WithInstrumentationAttributeSet` option to
`go.opentelemetry.io/otel/log`, `go.opentelemetry.io/otel/metric`, and
`go.opentelemetry.io/otel/trace` packages. This provides a
concurrent-safe and performant alternative to
`WithInstrumentationAttributes` by accepting a pre-constructed
`attribute.Set`. (#7287)
- Add experimental observability for the Prometheus exporter in
`go.opentelemetry.io/otel/exporters/prometheus`. Check the
`go.opentelemetry.io/otel/exporters/prometheus/internal/x` package
documentation for more information. (#7345)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#7353)
- Add temporality selector functions `DeltaTemporalitySelector`,
`CumulativeTemporalitySelector`, `LowMemoryTemporalitySelector` to
`go.opentelemetry.io/otel/sdk/metric`. (#7434)
- Add experimental observability metrics for simple log processor in
`go.opentelemetry.io/otel/sdk/log`. (#7548)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
(#7459)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#7486)
- Add experimental observability metrics for simple span processor in
`go.opentelemetry.io/otel/sdk/trace`. (#7374)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7512)
- Add experimental observability metrics for manual reader in
`go.opentelemetry.io/otel/sdk/metric`. (#7524)
- Add experimental observability metrics for periodic reader in
`go.opentelemetry.io/otel/sdk/metric`. (#7571)
- Support `OTEL_EXPORTER_OTLP_LOGS_INSECURE` and
`OTEL_EXPORTER_OTLP_INSECURE` environmental variables in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7608)
- Add `Enabled` method to the `Processor` interface in
`go.opentelemetry.io/otel/sdk/log`. All `Processor` implementations now
include an `Enabled` method. (#7639)
- The `go.opentelemetry.io/otel/semconv/v1.38.0` package. The package
contains semantic conventions from the `v1.38.0` version of the
OpenTelemetry Semantic Conventions. See the [migration
documentation](./semconv/v1.38.0/MIGRATION.md) for information on how to
upgrade from `go.opentelemetry.io/otel/semconv/v1.37.0.`(#7648)

### Changed

- `Distinct` in `go.opentelemetry.io/otel/attribute` is no longer
guaranteed to uniquely identify an attribute set. Collisions between
`Distinct` values for different Sets are possible with extremely high
cardinality (billions of series per instrument), but are highly
unlikely. (#7175)
- `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/trace`
synchronously de-duplicates the passed attributes instead of delegating
it to the returned `TracerOption`. (#7266)
- `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/meter`
synchronously de-duplicates the passed attributes instead of delegating
it to the returned `MeterOption`. (#7266)
- `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/log`
synchronously de-duplicates the passed attributes instead of delegating
it to the returned `LoggerOption`. (#7266)
- Rename the `OTEL_GO_X_SELF_OBSERVABILITY` environment variable to
`OTEL_GO_X_OBSERVABILITY` in `go.opentelemetry.io/otel/sdk/trace`,
`go.opentelemetry.io/otel/sdk/log`, and
`go.opentelemetry.io/otel/exporters/stdout/stdouttrace`. (#7302)
- Improve performance of histogram `Record` in
`go.opentelemetry.io/otel/sdk/metric` when min and max are disabled
using `NoMinMax`. (#7306)
- Improve error handling for dropped data during translation by using
`prometheus.NewInvalidMetric` in
`go.opentelemetry.io/otel/exporters/prometheus`. ⚠️ **Breaking Change:**
Previously, these cases were only logged and scrapes succeeded. Now,
when translation would drop data (e.g., invalid label/value), the
exporter emits a `NewInvalidMetric`, and Prometheus scrapes **fail with
HTTP 500** by default. To preserve the prior behavior (scrapes succeed
while errors are logged), configure your Prometheus HTTP handler with:
`promhttp.HandlerOpts{ ErrorHandling: promhttp.ContinueOnError }`.
(#7363)
- Replace fnv hash with xxhash in `go.opentelemetry.io/otel/attribute`
for better performance. (#7371)
- The default `TranslationStrategy` in
`go.opentelemetry.io/exporters/prometheus` is changed from
`otlptranslator.NoUTF8EscapingWithSuffixes` to
`otlptranslator.UnderscoreEscapingWithSuffixes`. (#7421)
- Improve performance of concurrent measurements in
`go.opentelemetry.io/otel/sdk/metric`. (#7427)
- Include W3C TraceFlags (bits 0–7) in the OTLP `Span.Flags` field in
`go.opentelemetry.io/exporters/otlp/otlptrace/otlptracehttp` and
`go.opentelemetry.io/exporters/otlp/otlptrace/otlptracegrpc`. (#7438)
- The `ErrorType` function in `go.opentelemetry.io/otel/semconv/v1.37.0`
now handles custom error types.
If an error implements an `ErrorType() string` method, the return value
of that method will be used as the error type. (#7442)

### Fixed

- Fix `WithInstrumentationAttributes` options in
`go.opentelemetry.io/otel/trace`, `go.opentelemetry.io/otel/metric`, and
`go.opentelemetry.io/otel/log` to properly merge attributes when passed
multiple times instead of replacing them. Attributes with duplicate keys
will use the last value passed. (#7300)
- The equality of `attribute.Set` when using the `Equal` method is not
affected by the user overriding the empty set pointed to by
`attribute.EmptySet` in `go.opentelemetry.io/otel/attribute`. (#7357)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`.
(#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
(#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#7372)
- Fix `AddAttributes`, `SetAttributes`, `SetBody` on `Record` in
`go.opentelemetry.io/otel/sdk/log` to not mutate input. (#7403)
- Do not double record measurements of `RecordSet` methods in
`go.opentelemetry.io/otel/semconv/v1.37.0`. (#7655)
- Do not double record measurements of `RecordSet` methods in
`go.opentelemetry.io/otel/semconv/v1.36.0`. (#7656)

### Removed

- Drop support for [Go 1.23]. (#7274)
- Remove the `FilterProcessor` interface in
`go.opentelemetry.io/otel/sdk/log`. The `Enabled` method has been added
to the `Processor` interface instead. All `Processor` implementations
must now implement the `Enabled` method. Custom processors that do not
filter records can implement `Enabled` to return `true`. (#7639)

Preeti Dewani 49292857b7 Replace fnv with xxhash (#7497) 
**Objective**:
- Performance comparison between fnv and xxhash in terms of ops/sec,
allocations and collisions
- Implement xxhash according to first objective

**Changes**:
- fnv is replaced by xxhash. 
  Perform stats:
  - **Collision**: No collision upto 100M
  - **Allocations**: Same in both cases
- **Ops/sec**: xxhash performed better in cases with medium to large
strings
 
 **Benchmarks**:
 ```

Flc゛ 80cb909774 refactor: replace context.Background() with t.Context()/b.Context() in tests (#7352) 
Based on the Go version we currently use, the dependency already
supports 1.24+, which allows using `t.Context()` and `b.Context()` in
unit tests and benchmarks respectively.

- Enable `context-background` and `context-todo` in
[`usetesting`](https://golangci-lint.run/docs/linters/configuration/#usetesting)
- Adjust the code to support linter detection

Andrew Wilkins e2da30d7d0 trace,metric,log: change WithInstrumentationAttributes to not de-depuplicate the passed attributes in a closure (#7266) 
WithInstrumentationAttributes is creating a closure with a reference to
a slice which is later passed to attribute.NewSet.

attribute.NewSet may mutate the slice, so this will lead to a data race
when the option is applied concurrently. We can fix this by moving the
call to attribute.NewSet outside the closure.

Fixes #7217

Robert Pająk 07a91dd2b0 trace,metric,log: add WithInstrumentationAttributeSet option (#7287) 
Per
https://github.com/open-telemetry/opentelemetry-go/pull/7266#issuecomment-3237027300

Related to
https://github.com/open-telemetry/opentelemetry-go/issues/7217

## What

This PR adds `WithInstrumentationAttributeSet` option functions to the
`log`, `metric`, and `trace` packages as suggested in
https://github.com/open-telemetry/opentelemetry-go/pull/7266#issuecomment-3237027300.
These new functions provide a more concurrent-safe alternative to the
existing `WithInstrumentationAttributes` functions by accepting a
pre-constructed `attribute.Set` instead of variadic `attribute.KeyValue`
parameters.

## Why

As discussed in #7266, the existing `WithInstrumentationAttributes`
functions can lead to data races when used concurrently because
`attribute.NewSet()` may mutate the passed slice in-place. While the
issue was partially addressed by moving the `attribute.NewSet()` call
outside the closure, the best long-term solution is to provide an
alternative that accepts an immutable `attribute.Set`.

**Benefits:**

1. **Concurrent Safety**: Since `attribute.Set` is immutable, these
functions are inherently safe for concurrent use
2. **Performance**: Avoids repeated calls to `attribute.NewSet()` when
the same attributes are used multiple times
3. **Consistency**: Matches the existing pattern used in
`metric.WithAttributeSet()`
4. **Flexibility**: Allows users to pre-compute attribute sets and reuse
them

Deprecating `WithInstrumentationAttributes` is out of scope. See
https://github.com/open-telemetry/opentelemetry-go/pull/7287#issuecomment-3245820459.

Robert Pająk dcf14aa937 trace,metric,log: WithInstrumentationAttributes options to merge attributes (#7300) 
## What

Fix `WithInstrumentationAttributes` options in
`go.opentelemetry.io/otel/trace`, `go.opentelemetry.io/otel/metric`, and
`go.opentelemetry.io/otel/log` to properly merge attributes when passed
multiple times instead of replacing them. Attributes with duplicate keys
will use the last value passed.

## Why

Per
https://github.com/open-telemetry/opentelemetry-go/pull/7287#pullrequestreview-3181379062
and
https://github.com/open-telemetry/opentelemetry-go/pull/7287#issuecomment-3250085450

Not that this does not address
https://github.com/open-telemetry/opentelemetry-go/issues/7217. This is
left to a seperate PR to not scope creep this one. CC @axw

instead of `runtime.NumCPU()` for the `FixedSizeReservoirProvider`
default size. (#7094)

### Fixed

- `SetBody` method of `Record` in `go.opentelemetry.io/otel/sdk/log` now
deduplicates key-value collections (`log.Value` of `log.KindMap` from

[Compare
Source](https://redirect.github.com/stretchr/testify/compare/v1.11.0...v1.11.1)

This release fixes
[#&#8203;1785](https://redirect.github.com/stretchr/testify/issues/1785)
introduced in v1.11.0 where expected argument values implementing the
stringer interface (`String() string`) with a method which mutates their
value, when passed to mock.Mock.On (`m.On("Method",
<expected>).Return()`) or actual argument values passed to
mock.Mock.Called may no longer match one another where they previously
did match. The behaviour prior to v1.11.0 where the stringer is always
called is restored. Future testify releases may not call the stringer
method at all in this case.

Damien Mathieu a85ae98dce Release v1.36.0/v0.58.0/v0.12.0 (#6793) 
# Overview

Closes https://github.com/open-telemetry/opentelemetry-go/issues/6786

### Added

- Add exponential histogram support in
`go.opentelemetry.io/otel/exporters/prometheus`. (#6421)
- The `go.opentelemetry.io/otel/semconv/v1.31.0` package.
The package contains semantic conventions from the `v1.31.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.31.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.30.0`. (#6479)
- Add `Recording`, `Scope`, and `Record` types in
`go.opentelemetry.io/otel/log/logtest`. (#6507)
- Add `WithHTTPClient` option to configure the `http.Client` used by
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#6751)
- Add `WithHTTPClient` option to configure the `http.Client` used by
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#6752)
- Add `WithHTTPClient` option to configure the `http.Client` used by
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#6688)
- Add `ValuesGetter` in `go.opentelemetry.io/otel/propagation`, a
`TextMapCarrier` that supports retrieving multiple values for a single
key. (#5973)
- Add `Values` method to `HeaderCarrier` to implement the new
`ValuesGetter` interface in `go.opentelemetry.io/otel/propagation`.
(#5973)
- Update `Baggage` in `go.opentelemetry.io/otel/propagation` to retrieve
multiple values for a key when the carrier implements `ValuesGetter`.
(#5973)
- Add `AssertEqual` function in `go.opentelemetry.io/otel/log/logtest`.
(#6662)
- The `go.opentelemetry.io/otel/semconv/v1.32.0` package.
The package contains semantic conventions from the `v1.32.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.32.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.31.0`(#6782)
- Add `Transform` option in `go.opentelemetry.io/otel/log/logtest`.
(#6794)
- Add `Desc` option in `go.opentelemetry.io/otel/log/logtest`. (#6796)

### Removed

- Drop support for [Go 1.22]. (#6381, #6418)
- Remove `Resource` field from `EnabledParameters` in
`go.opentelemetry.io/otel/sdk/log`. (#6494)
- Remove `RecordFactory` type from
`go.opentelemetry.io/otel/log/logtest`. (#6492)
- Remove `ScopeRecords`, `EmittedRecord`, and `RecordFactory` types from
`go.opentelemetry.io/otel/log/logtest`. (#6507)
- Remove `AssertRecordEqual` function in
`go.opentelemetry.io/otel/log/logtest`, use `AssertEqual` instead.
(#6662)

### Changed

- ⚠️ Update `github.com/prometheus/client_golang` to `v1.21.1`, which
changes the `NameValidationScheme` to `UTF8Validation`.
This allows metrics names to keep original delimiters (e.g. `.`), rather
than replacing with underscores.
This can be reverted by setting
`github.com/prometheus/common/model.NameValidationScheme` to
`LegacyValidation` in `github.com/prometheus/common/model`. (#6433)
- Initialize map with `len(keys)` in `NewAllowKeysFilter` and
`NewDenyKeysFilter` to avoid unnecessary allocations in
`go.opentelemetry.io/otel/attribute`. (#6455)
- `go.opentelemetry.io/otel/log/logtest` is now a separate Go module.
(#6465)
- `go.opentelemetry.io/otel/sdk/log/logtest` is now a separate Go
module. (#6466)
- `Recorder` in `go.opentelemetry.io/otel/log/logtest` no longer
separately stores records emitted by loggers with the same
instrumentation scope. (#6507)
- Improve performance of `BatchProcessor` in
`go.opentelemetry.io/otel/sdk/log` by not exporting when exporter cannot
accept more. (#6569, #6641)

### Deprecated

- Deprecate support for `model.LegacyValidation` for
`go.opentelemetry.io/otel/exporters/prometheus`. (#6449)

### Fixes

- Stop percent encoding header environment variables in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc` and
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#6392)
- Ensure the `noopSpan.tracerProvider` method is not inlined in
`go.opentelemetry.io/otel/trace` so the `go.opentelemetry.io/auto`
instrumentation can instrument non-recording spans. (#6456)
- Use a `sync.Pool` instead of allocating `metricdata.ResourceMetrics`
in `go.opentelemetry.io/otel/exporters/prometheus`. (#6472)

Sean Liao a571c52b0a all: replace math/rand with math/rand/v2 (#6732) 
Update to new stdlib apis.

The new Float64 is uniform, which resolves a long comment.

> // There are exactly 1<<53 float64s in [0,1). Use Intn(1<<53) /
(1<<53).
	return float64(r.Uint64()<<11>>11) / (1 << 53)

Sam Xie 09ff8b107a Drop support for Go 1.22 (#6381) 2025-03-05 22:23:10 -08:00
Sam Xie 5ba5e7a449 Release v1.35.0/v0.57.0/v0.11.0 (#6407) 
## Overview

This release is the last to support [Go 1.22].
The next release will require at least [Go 1.23].

### Added

- Add `ValueFromAttribute` and `KeyValueFromAttribute` in
`go.opentelemetry.io/otel/log`. (#6180)
- Add `EventName` and `SetEventName` to `Record` in
`go.opentelemetry.io/otel/log`. (#6187)
- Add `EventName` to `RecordFactory` in
`go.opentelemetry.io/otel/log/logtest`. (#6187)
- `AssertRecordEqual` in `go.opentelemetry.io/otel/log/logtest` checks
`Record.EventName`. (#6187)
- Add `EventName` and `SetEventName` to `Record` in
`go.opentelemetry.io/otel/sdk/log`. (#6193)
- Add `EventName` to `RecordFactory` in
`go.opentelemetry.io/otel/sdk/log/logtest`. (#6193)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#6211)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#6211)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/stdout/stdoutlog` (#6210)
- The `go.opentelemetry.io/otel/semconv/v1.28.0` package.
The package contains semantic conventions from the `v1.28.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.28.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.27.0`(#6236)
- The `go.opentelemetry.io/otel/semconv/v1.30.0` package.
The package contains semantic conventions from the `v1.30.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.30.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.28.0`(#6240)
- Document the pitfalls of using `Resource` as a comparable type.
`Resource.Equal` and `Resource.Equivalent` should be used instead.
(#6272)
- Support [Go 1.24]. (#6304)
- Add `FilterProcessor` and `EnabledParameters` in
`go.opentelemetry.io/otel/sdk/log`.
It replaces
`go.opentelemetry.io/otel/sdk/log/internal/x.FilterProcessor`.
Compared to previous version it additionally gives the possibility to
filter by resource and instrumentation scope. (#6317)

### Changed

- Update `github.com/prometheus/common` to v0.62.0., which changes the
`NameValidationScheme` to `NoEscaping`. This allows metrics names to
keep original delimiters (e.g. `.`), rather than replacing with
underscores. This is controlled by the `Content-Type` header, or can be
reverted by setting `NameValidationScheme` to `LegacyValidation` in
`github.com/prometheus/common/model`. (#6198)

### Fixes

- Eliminate goroutine leak for the processor returned by
`NewSimpleSpanProcessor` when `Shutdown` is called and the passed `ctx`
is canceled and `SpanExporter.Shutdown` has not returned. (#6368)
- Eliminate goroutine leak for the processor returned by
`NewBatchSpanProcessor` when `ForceFlush` is called and the passed `ctx`
is canceled and `SpanExporter.Export` has not returned. (#6369)

Tyler Yahn edc378fa8d Release v1.34.0/v0.56.0/v0.10.0 (#6174) 
## Overview

### Changed

- Remove the notices from `Logger` to make the whole Logs API
user-facing in `go.opentelemetry.io/otel/log`. (#6167)

### Fixed

- Relax minimum Go version to 1.22.0 in various modules. (#6073)
- The `Type` name logged for the
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` client
is corrected from `otlphttpgrpc` to `otlptracegrpc`. (#6143)
- The `Type` name logged for the
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlphttpgrpc` client
is corrected from `otlphttphttp` to `otlptracehttp`. (#6143)
 2025-01-17 08:21:54 -08:00
Tyler Yahn 8c38f80ec3 Release v1.33.0 (#6035) 
### Added

- Add `Reset` method to `SpanRecorder` in
`go.opentelemetry.io/otel/sdk/trace/tracetest`. (#5994)
- Add `EnabledInstrument` interface in
`go.opentelemetry.io/otel/sdk/metric/internal/x`. This is an
experimental interface that is implemented by synchronous instruments
provided by `go.opentelemetry.io/otel/sdk/metric`. Users can use it to
avoid performing computationally expensive operations when recording
measurements. It does not fall within the scope of the OpenTelemetry Go
versioning and stability [policy](./VERSIONING.md) and it may be changed
in backwards incompatible ways or removed in feature releases. (#6016)

### Changed

- The default global API now supports full auto-instrumentation from the
`go.opentelemetry.io/auto` package. See that package for more
information. (#5920)
- Propagate non-retryable error messages to client in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#5929)
- Propagate non-retryable error messages to client in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#5929)
- Propagate non-retryable error messages to client in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#5929)
- Performance improvements for attribute value `AsStringSlice`,
`AsFloat64Slice`, `AsInt64Slice`, `AsBoolSlice`. (#6011)
- Change `EnabledParameters` to have a `Severity` field instead of a
getter and setter in `go.opentelemetry.io/otel/log`. (#6009)

### Fixed

- Fix inconsistent request body closing in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#5954)
- Fix inconsistent request body closing in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#5954)
- Fix inconsistent request body closing in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.

`go.opentelemetry.io/otel/exporters/prometheus`. (#5995)
- Fix attribute value truncation in
`go.opentelemetry.io/otel/sdk/trace`. (#5997)
- Fix attribute value truncation in `go.opentelemetry.io/otel/sdk/log`.

Tyler Yahn 99c3c661e0 Use auto-instrumentation SDK in global tracing (#5920) 
When the auto-instrumentation attaches to a process using the global
TracerProvider, and there has not been a delegate set, create a span
from the go.opentelemetry.io/auto/sdk package so the OTel Go
auto-instrumentation can instrument the application by default.

Resolve #5702
