Joe Stephenson 5da6cd28a8 sdk/log: Add WithAllowKeyDuplication logger provider option (#6968)
Closes #5133 

This couldn't be added as an option on a processor, as that would
involve moving all the attribute deduplication. logic outside of the
record type. Instead this PR provides the same functionality but it is
set when creating the log provider

The below benchstat report shows the performance improvement when
`allowDupKeys` is set

Robert Pająk a99f9b56ce sdk/log: Record.Resource to return *resource.Resource (#6864)
Fixes https://github.com/open-telemetry/opentelemetry-go/issues/6863

From https://pkg.go.dev/go.opentelemetry.io/otel/sdk/resource#Resource:

> Resource is an immutable object
> [...]
> Resources should be passed and stored as pointers
(`*resource.Resource`)

In all other places the exported API uses `*resource.Resource` and not
`resource.Resource`.

# 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)

Igor a5abd88e1d Optimize Logs SDK BatchProcessor (#6569)
Towards: https://github.com/open-telemetry/opentelemetry-go/issues/6382

This PR optimizes Logs SDK BatchProcessor.

## Why? <!-- was i so blind -->

Batch processor does not check if buffer exporter is full, instead it
clones records to buffer, then tries to push them to buffer exporter,
and then buffer exporter will return false from EnqueueExport if it is
full.

It does not cause any performance issues when using NOOP exporter,
because it "exports" instantly. -> Buffer exporter input channel will
almost never be full.

But actual implementations of exporters are not going to act that way,
they need some time for export operation. And so buffer exporter will
get full fairly frequently. Each export attempt to buffer exporter costs
us copying entire queue inside of batch processor.

In order to catch this or similar performance bottleneck in the future,
new benchmark (`BatchSimulateExport`) was added which will use exporter
that will simulate non-instant export by sleeping for 5ms.

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)

Robert Pająk 1ee7c79b73 sdk/log: Add FilterProcessor and EnabledParameters (#6317)
Per
https://github.com/open-telemetry/opentelemetry-go/pull/6271#issuecomment-2657554647

> We agreed that we can move `FilterProcessor` directly to `sdk/log` as
Logs SDK does not look to be stabilized soon.

- Add the possibility to filter based on the resource and scope which is
available for the SDK. The scope information is the most important as it
gives the possibility to e.g. filter out logs emitted for a given
logger. Thus e.g.
https://github.com/open-telemetry/opentelemetry-specification/issues/4364
is not necessary. See
https://github.com/open-telemetry/opentelemetry-specification/pull/4290#discussion_r1927546170
for more context.
- It is going be an example for
https://github.com/open-telemetry/opentelemetry-specification/issues/4363

There is a little overhead (IMO totally acceptable) because of data
transformation. Most importantly, there is no new heap allocation.

`Logger.Enabled` is still more efficient than `Logger.Emit` (benchmarks
from https://github.com/open-telemetry/opentelemetry-go/pull/6315).

Robert Pająk 55ff06fbdd sdk/log: Change BenchmarkLoggerNewRecord to BenchmarkLoggerEmit (#6315)
I find having benchmark for `Emit` more useful than just for
`newRecord`.
It can be used to showcase the performance benefit of using `Enabled`
even for a record with 10 attributes.

Robert Pająk 078a4a844f sdk/log: Assign fltrProcessors on provider creation instead of lazy (#6239)
I think it is better to calculate fltrProcessors upfront instead of
doing it in a lazy manner. Reasons:

- No locks/synchronization in the hot-path. Even though the performance
overhead is not big (in practice it will be usually unnoticeable, in my
benchmark execution it is less than a nanosecond) I think it is good to
minimize locking on the hot path.
- Simpler code (subjective, but at least less code by 9 lines)

2025-01-05 09:26:07 -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`.
(#5954)
- Fix invalid exemplar keys in
`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`.
(#6032)
2024-12-12 09:54:13 -08:00
Tyler Yahn aa95895dfa Fix sdk/log record attr value limit (#6032)
Fix #6004 

Copy of #5997

### Correctness

From the [OTel
specification](https://github.com/open-telemetry/opentelemetry-specification/blob/88bffeac48aa5eb37ac8044e931af63a0b55fe00/specification/common/README.md#attribute-limits):

> - set an attribute value length limit such that for each attribute
value:
> - if it is a string, if it exceeds that limit (counting any character
in it as 1), SDKs MUST truncate that value, so that its length is at
most equal to the limit...

Our current implementation truncates on number of bytes not characters.

Unit tests are added/updated to validate this fix and prevent
regressions.

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

Robert Pająk 7cfbd86a60 Release v1.32.0/v0.54.0/v0.8.0/v0.0.11 (#5960)
### Added

- Add `go.opentelemetry.io/otel/sdk/metric/exemplar.AlwaysOffFilter`,
which can be used to disable exemplar recording. (#5850)
- Add `go.opentelemetry.io/otel/sdk/metric.WithExemplarFilter`, which
can be used to configure the exemplar filter used by the metrics SDK.
(#5850)
- Add `ExemplarReservoirProviderSelector` and
`DefaultExemplarReservoirProviderSelector` to
`go.opentelemetry.io/otel/sdk/metric`, which defines the exemplar
reservoir to use based on the aggregation of the metric. (#5861)
- Add `ExemplarReservoirProviderSelector` to
`go.opentelemetry.io/otel/sdk/metric.Stream` to allow using views to
configure the exemplar reservoir to use for a metric. (#5861)
- Add `ReservoirProvider`, `HistogramReservoirProvider` and
`FixedSizeReservoirProvider` to
`go.opentelemetry.io/otel/sdk/metric/exemplar` to make it convenient to
use providers of Reservoirs. (#5861)
- The `go.opentelemetry.io/otel/semconv/v1.27.0` package.
The package contains semantic conventions from the `v1.27.0` version of
the OpenTelemetry Semantic Conventions. (#5894)
- Add `Attributes attribute.Set` field to `Scope` in
`go.opentelemetry.io/otel/sdk/instrumentation`. (#5903)
- Add `Attributes attribute.Set` field to `ScopeRecords` in
`go.opentelemetry.io/otel/log/logtest`. (#5927)
- `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` adds
instrumentation scope attributes. (#5934)
- `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` adds
instrumentation scope attributes. (#5934)
- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`
adds instrumentation scope attributes. (#5935)
- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`
adds instrumentation scope attributes. (#5935)
- `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc` adds
instrumentation scope attributes. (#5933)
- `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp` adds
instrumentation scope attributes. (#5933)
- `go.opentelemetry.io/otel/exporters/prometheus` adds instrumentation
scope attributes in `otel_scope_info` metric as labels. (#5932)

### Changed

- Support scope attributes and make them as identifying for `Tracer` in
`go.opentelemetry.io/otel` and `go.opentelemetry.io/otel/sdk/trace`.
(#5924)
- Support scope attributes and make them as identifying for `Meter` in
`go.opentelemetry.io/otel` and `go.opentelemetry.io/otel/sdk/metric`.
(#5926)
- Support scope attributes and make them as identifying for `Logger` in
`go.opentelemetry.io/otel` and `go.opentelemetry.io/otel/sdk/log`.
(#5925)
- Make schema URL and scope attributes as identifying for `Tracer` in
`go.opentelemetry.io/otel/bridge/opentracing`. (#5931)
- Clear unneeded slice elements to allow GC to collect the objects in
`go.opentelemetry.io/otel/sdk/metric` and
`go.opentelemetry.io/otel/sdk/trace`. (#5804)

### Fixed

- Global MeterProvider registration unwraps global instrument Observers,

	clear(sink)
	sink = sink[:0]
	runtime.GC()
	var ms runtime.MemStats
	runtime.ReadMemStats(&ms)
	b.Log(b.N, ms.Frees) // Frees is the cumulative count of heap objects freed.
}
```

```

This is documented at https://go.dev/wiki/SliceTricks:

> NOTE If the type of the element is a pointer or a struct with pointer
fields, which need to be garbage collected, the above implementations of
Cut and Delete have a potential memory leak problem: some elements with
values are still referenced by slice a’s underlying array, just not
“visible” in the slice. Because the “deleted” value is referenced in the
underlying array, the deleted value is still “reachable” during GC, even
though the value cannot be referenced by your code. If the underlying
array is long-lived, this represents a leak.

Followed by examples of how zeroing out the slice elements solves
the problem. This PR does the same.

David Ashpole bc2fe88756 Release v1.31.0/v0.53.0/v0.7.0/v0.0.10 (#5883)
### Added

- Add `go.opentelemetry.io/otel/sdk/metric/exemplar` package which
includes `Exemplar`, `Filter`, `TraceBasedFilter`, `AlwaysOnFilter`,
`HistogramReservoir`, `FixedSizeReservoir`, `Reservoir`, `Value` and
`ValueType` types. These will be used for configuring the exemplar
reservoir for the metrics sdk. (#5747, #5862)
- Add `WithExportBufferSize` option to log batch processor.(#5877)

### Changed

- Enable exemplars by default in `go.opentelemetry.io/otel/sdk/metric`.
Exemplars can be disabled by setting
`OTEL_METRICS_EXEMPLAR_FILTER=always_off` (#5778)
- `Logger.Enabled` in `go.opentelemetry.io/otel/log` now accepts a newly
introduced `EnabledParameters` type instead of `Record`. (#5791)
- `FilterProcessor.Enabled` in
`go.opentelemetry.io/otel/sdk/log/internal/x` now accepts
`EnabledParameters` instead of `Record`. (#5791)
- The `Record` type in `go.opentelemetry.io/otel/log` is no longer
comparable. (#5847)
- Performance improvements for the trace SDK `SetAttributes` method in
`Span`. (#5864)
- Reduce memory allocations for the `Event` and `Link` lists in `Span`.
(#5858)
- Performance improvements for the trace SDK `AddEvent`, `AddLink`,
`RecordError` and `End` methods in `Span`. (#5874)

### Deprecated

- Deprecate all examples under `go.opentelemetry.io/otel/example` as
they are moved to [Contrib
repository](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/examples).
(#5854)

### Fixed

- The race condition for multiple `FixedSize` exemplar reservoirs
identified in #5814 is resolved. (#5819)
- Fix log records duplication in case of heterogeneous resource
attributes by correctly mapping each log record to it's resource and
scope. (#5803)
- Fix timer channel drain to avoid hanging on Go 1.23. (#5868)
- Fix delegation for global meter providers, and panic when calling
otel.SetMeterProvider. (#5827)
- Change the `reflect.TypeOf` to use a nil pointer to not allocate on
the heap unless necessary. (#5827)
