David Ashpole 5bd5702ad2 Fix stale status code reporting on self-observability metrics (#8226)
Fixes https://github.com/open-telemetry/opentelemetry-go/issues/8218

This now omits the status code attribute when a request fails before
getting a response, and doesn't use the previous response's status code
when reporting self-observability metrics.

Robert Pająk fa9276b15e exporters: support SLICE attributes (#8216)
Fixes #8162

Follow-up to #8153 for `attribute.SLICE`.

Add end-to-end exporter handling for `attribute.SLICE` in the remaining
paths that still treated it as invalid or relied on fallback formatting.

Changes:

- encode `attribute.SLICE` as OTLP `AnyValue_ArrayValue` for trace, log,
and metric transforms
- serialize Zipkin `SLICE` attributes using the non-OTLP AnyValue string
representation
- add trace-side coverage for recursive `convAttrValue` slice conversion

Robert Pająk bec9f66b45 sdk/trace: apply AttributeValueLengthLimit to attribute.SLICE (#8217)
Fixes #7955

Per the OTel spec, attribute value limits must be applied recursively to
array elements. Previously truncateAttr only handled STRING and
STRINGSLICE.

Add a SLICE case to truncateAttr and two unexported helpers:
- truncateValue: recursively truncates STRING, STRINGSLICE, and SLICE
- needsTruncation: pre-scan guard that avoids allocating a new slice
when no element would be modified (mirrors sdk/log's pattern)

```

The new `attribute.SLICE` item makes
`BenchmarkSpanLimits/AttributeValueLengthLimit` ~12% slower with 5 extra
allocs in that path compared to `main`. This is fine as 3 strings and 2
arrays need to be allocated because of the limits+truncation.

Ali Asghar c56c84380c sdk/trace: propagate SpanExporter.Shutdown error from BatchSpanProcessor (#8197)
Fixes #6878.

`bsp.e.Shutdown(ctx)` was called with `:=` inside an `if` statement,
creating a new variable that shadowed the outer `err`. The error was
handled via `otel.Handle` but never returned to the caller of
`BatchSpanProcessor.Shutdown`.

### Fix

Use a dedicated `exportErr` variable. The goroutine writes it before
closing the `wait` channel; the caller reads it only in the `<-wait`
select case (where the goroutine is guaranteed done). This is race-free
— addressing the concern raised by @seh in #6878.

All existing `TestBatchSpanProcessor*` tests pass.

- The undocumented TRAP cache cleanup feature that could be enabled
using the `CODEQL_ACTION_CLEANUP_TRAP_CACHES` environment variable is
deprecated and will be removed in May 2026. If you are affected by this,
we recommend disabling TRAP caching by passing the `trap-caching: false`
input to the `init` Action.
[#&#8203;3795](https://redirect.github.com/github/codeql-action/pull/3795)
- The Git version 2.36.0 requirement for improved incremental analysis
now only applies to repositories that contain submodules.
[#&#8203;3789](https://redirect.github.com/github/codeql-action/pull/3789)
- Python analysis on GHES no longer extracts the standard library,
relying instead on models of the standard library. This should result in
significantly faster extraction and analysis times, while the effect on
alerts should be minimal.
[#&#8203;3794](https://redirect.github.com/github/codeql-action/pull/3794)

Robert Pająk fbbc5a6045 attribute: make TestHashKVs linear-time (#8204)
Unblocks https://github.com/open-telemetry/opentelemetry-go/pull/8166

Per
https://github.com/open-telemetry/opentelemetry-go/pull/8166#issuecomment-4246787382

## Why

This updates `TestHashKVsEquality` to avoid the quadratic pairwise
comparison that was causing slow runs and timeouts in CI.

Below are the results from my machine.

Old:

```
$ go test -run=TestHashKVs -count=1 
PASS
ok      go.opentelemetry.io/otel/attribute      2.063s
```

New:

```
$ go test -run=TestHashKVs -count=1 
PASS
ok      go.opentelemetry.io/otel/attribute      0.024s
```

Instead of collecting every generated testcase and comparing each hash
against every other hash, the test now checks uniqueness as each case is
generated by storing previously seen hashes in a map. Note that it also
does not use the equality operator of `KeyValue` to determine if the
hash should be equal or different.

## What 

- Rename the test from `TestHashKVsEquality` to `TestHashKVs`
- Replace the O(n^2) post-processing loop with an O(n) streaming
uniqueness check
- Simplify failure reporting by removing the dedicated `msg` helper

Side note: for me it also makes the test more readable (however, this is
opinionated).

The actual default reservoir provider uses runtime.GOMAXPROCS(0) to work

fact that the test used runtime.NumCPU() caused the test to fail.

Robert Pająk 0231f02f59 fix(otlpmetrichttp): replay gzipped bodies on redirect (#8185)
Same as https://github.com/open-telemetry/opentelemetry-go/pull/8152 but
for `otlpmetrichttp`

When gzip compression is enabled, the OTLP metric HTTP client compressed
the request body for the initial send but left GetBody wired to the
original uncompressed protobuf payload.

Any redirect or retry path that rebuilt the request from GetBody could
then resend an uncompressed body while still advertising
Content-Encoding: gzip.

Update GetBody to return the gzipped buffer and add a redirect
regression test that verifies the replayed body matches the original
compressed request and can be decompressed successfully.

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 fe35606998 Update semconv template and 1.40.0 to use Enabled for metrics (#8172)
Part of https://github.com/open-telemetry/opentelemetry-go/issues/7800

This adds Enabled checks to the generated semconv metric instruments. I
also opted to regenerate the 1.40.0 conventions given this is not a
behavioral change.

While implementing it, I did get the sense that this _should_ be
redundant. Callers should be checking Enabled before making these calls
because they should avoid building attribute sets. But it does still
make sense to have this as a fallback for cases where callers haven't
done that.

([#&#8203;15040](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15040))
  To better match the feature flag README

(<https://github.com/open-telemetry/opentelemetry-collector/blob/main/featuregate/README.md#feature-lifecycle>).

##### 🧰 Bug fixes 🧰

- `exporter/debug`: Guard from out of bounds profiles dictionary indices
([#&#8203;14803](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14803))

- `pdata/pprofile`: create a copy when the input is marked as read-only
([#&#8203;15080](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15080))

- `pkg/otelcol`: Fix missing default values in unredacted print-config
command by introducing confmap.WithUnredacted MarshalOption.
([#&#8203;14750](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14750))
Resolves an issue where the unredacted mode output omitted all
default-valued options. By introducing a new MarshalOption to disable
redaction directly at the confmap encoding level, the unredacted mode
now preserves all component defaults natively without requiring
post-processing.

- `pkg/service`: Headers on the internal telemetry OTLP exporter are now
redacted when the configuration is marshaled
([#&#8203;14756](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14756))

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

Tyler Yahn b1284dbfaa Support BYTESLICE attributes across trace and exporter paths (#8153)
Fixes https://github.com/open-telemetry/opentelemetry-go/issues/8164

Supersedes #8042 which does not address the `trace` or `zipkin`
packages, and has unrelated support changes.

Add end-to-end handling for `attribute.BYTESLICE` in the remaining trace
and exporter paths that still dropped, invalidated, or stringified byte
slice attributes.

This change:

- preserves byte slice attributes in `trace/auto`
- encodes byte slice attributes as OTLP `AnyValue_BytesValue` in trace,
log, and metric transforms
- serializes Zipkin byte slice attributes as JSON arrays of byte values
- adds regression tests for each updated path

## Problem

`attribute.BYTESLICE` is public, but several downstream conversions
still did not handle it correctly:

- `trace/auto` dropped byte slice attributes during conversion
- OTLP trace, log, and metric transforms fell through to their invalid
default handling
- Zipkin fell back to `Value.Emit()`, which produced a base64 string
rather than an explicit byte-array representation

That made `BYTESLICE` unusable or inconsistent depending on the export
path.

## Changes

### Trace

- Handle `attribute.BYTESLICE` in `trace/auto` by converting it to an
internal telemetry bytes value.
- Add a regression test covering byte slice conversion.

### OTLP

- Handle `attribute.BYTESLICE` in:
  - trace attribute transform
  - log gRPC attribute transform
  - log HTTP attribute transform
  - metric HTTP attribute transform
  - metric gRPC attribute transform
- Update the shared log and metric transform templates so generated
outputs stay aligned.
- Add regression tests for the trace transform, both log transform
outputs, and both metric transform outputs.

### Zipkin

- Handle `attribute.BYTESLICE` explicitly in Zipkin tag serialization.
- Serialize byte slices as JSON arrays of byte values instead of base64
text.
- Add a regression test for Zipkin byte slice serialization.

David Ashpole 0c09e08e7f Add experimental support for batching in periodic reader (#8071)
Adds experimental support for maxExportBatchSize using the
`OTEL_GO_X_METRIC_EXPORT_BATCH_SIZE=<size>` environment variable.

Previous prototype:
https://github.com/open-telemetry/opentelemetry-go/pull/7930

This preserves existing behavior for timeouts when batching is not used,
but individually applies the timeout to export calls when batching is
used.
