chore(deps): update module github.com/cyphar/filepath-securejoin to v0.7.0 ( #8486 )
...
This PR contains the following updates:
| Package | Change |

[Confidence](https://docs.renovatebot.com/merge-confidence/ ) |
|---|---|---|---|
|
[github.com/cyphar/filepath-securejoin](https://redirect.github.com/cyphar/filepath-securejoin )
| `v0.6.1` → `v0.7.0` |
|
|
---
### Release Notes
<details>
<summary>cyphar/filepath-securejoin
(github.com/cyphar/filepath-securejoin)</summary>
###
[`v0.7.0`](https://redirect.github.com/cyphar/filepath-securejoin/releases/tag/v0.7.0 ):
-- "You talk of times of peace for all, and then prepare for war."
[Compare
Source](https://redirect.github.com/cyphar/filepath-securejoin/compare/v0.6.1...v0.7.0 )
##### Changed
- Update to `cyphar.com/go-pathrs@0.2.5`, which included a build-time
API
breakage that we needed to work around. The API of this library is
unchanged
by this, but users should make sure to update to `v0.7.0` of
`filepath-securejoin` if they use the `libpathrs` built tag and have
update
to `libpathrs` `v0.2.5`.

attribute: test map equivalence with duplicate keys ( #8473 )
...
Add coverage documenting the map equivalence behavior for duplicated
keys.
This follows the prior-art semantics of `attribute.Set`.
Side note: there is already a `duplicate keys keep stable order` test
case in `TestAsMap`. However, I think that adding these test cases is a
good coverage addition.

attribute: inline hashing for small SLICE and MAP values ( #8476 )
...
Fixes #8450
Inlining the hashing logic for SLICE and MAP values of sizes 1 to 5
avoids slice header construction and function call overhead.
Our benchmark results show:
- Hashing speed improved by ~20% to ~44% across small slices and maps
- Heap allocations are completely eliminated (reduced from 1 to 0
allocs/op)
```

sdk: deduplicate MAP attribute keys ( #8471 )
...
Fixes https://github.com/open-telemetry/opentelemetry-go/issues/7957 .
- Remove duplicate keys from `attribute.MAP` values by default across
SDK resource, log, trace, and metric export paths, including top-level
MAP-valued attributes and MAP values nested inside MAP or SLICE values.
- Update `log.WithAllowKeyDuplication()` behavior and docs.
- Always deduplicate MAP values in resources;
`go.opentelemetry.io/otel/sdk/resource` does not provide an opt-out.
Resources are typically evaluated once at startup or occasionally
updated. The ~12.90% overhead shown in benchmarks will have low impact
on an application's runtime latency, and having a strictly normalized
Resource map prevents downstream exporter issues.
- Preserve top-level `attribute.Set` behavior for resources, scopes, and
metric datapoint attributes; this change normalizes MAP-valued attribute
values, not the outer attribute collection semantics.
- Use last-value-wins semantics and do not increment dropped-attribute
counts for MAP duplicate removal.
- Keep internal helper code scoped per module: shared source lives in
`internal/shared/attrdedup`, then `gotmpl` renders module-local copies
under `sdk/internal`, `sdk/log/internal`, and `sdk/metric/internal`.
## Benchmarks
Baseline benchmarks were run from a local `main` worktree at
`/tmp/opentelemetry-go-main`; branch benchmarks were run from this
branch. All comparisons use `-benchmem -count=10`.

## Rejected implementations
### Seen-Pool
I tested an alternative `deduplicateMapValue` implementation using a
pooled `map[string]struct{}` for duplicate detection, modeled after
`sdk/log.Record`'s `seenPool`. The candidate was not kept because it
regressed all non-opt-out helper benchmark paths.
```console
pkg: go.opentelemetry.io/otel/sdk/internal/attrdedup
│ baseline │ seenpool │
│ sec/op │ sec/op vs base │
Value/FastPath-20 143.8n ± 0% 201.6n ± 0% +40.15% (p=0.000 n=20)
Value/DuplicateMap-20 669.8n ± 9% 862.9n ± 12% +28.83% (p=0.000 n=20)
Value/NestedMapInSlice-20 918.2n ± 9% 1115.0n ± 5% +21.43% (p=0.000 n=20)
Value/AllowKeyDuplication-20 1.324n ± 0% 1.324n ± 0% ~ (p=0.389 n=20)
geomean 104.0n 126.6n +21.68%
```
The candidate did not change allocation counts, but the `sync.Pool` and
map operations added measurable CPU overhead.
### Needs-Style Preflight
I tested an alternative implementation modeled after
`sdk/log.Record.needsValueLimitsOrDedup`: first scan attribute values to
determine whether normalization is needed, then normalize only when the
scan says a value would change.
The refined candidate preserved the opt-out fast path and avoided an
extra slice preflight pass, but was not kept because package-level
benchmark results were mixed: resource improved, but trace and metric
regressed.

```console

```
All candidate allocation geomeans were unchanged. Because the candidate
did not improve performance consistently across affected export paths,
this PR keeps the original lazy allocation-free no-op implementation.

Changes:
- encode `attribute.MAP` as OTLP `AnyValue_AnyValue_KvlistValue` for
trace, log, and metric transforms
- serialize Zipkin `MAP` attributes using the non-OTLP AnyValue string
representation

sdk/trace: apply AttributeValueLengthLimit to attribute.MAP ( #8454 )
...
Fixes #7956
Per the OTel spec, attribute value limits must be applied recursively to
map values. Previously `truncateAttr` handled `STRING`, `STRINGSLICE`,
`BYTESLICE`, and `SLICE`, but not `MAP`.
Add `MAP` handling to the trace SDK attribute limiter:
- `truncateAttr`: truncates `attribute.MAP` values when needed.
- `truncateValue`: recursively truncates `MAP`, `SLICE`, `STRINGSLICE`,
`STRING`, and `BYTESLICE` values.
- `needsTruncation`: pre-scan guard for `MAP` values to avoid rebuilding
when no nested value changes.
`benchstat` for `BenchmarkSpanLimits/AttributeValueLengthLimit`
(`count=10`):
```
SpanLimits/AttributeValueLengthLimit-20 14.88µ ± 16% 15.56µ ± 53% ~ (p=0.739 n=10)
SpanLimits/AttributeValueLengthLimit-20 12.71Ki ± 0% 13.66Ki ± 0% +7.52% (p=0.000 n=10)
SpanLimits/AttributeValueLengthLimit-20 47.00 ± 0% 56.00 ± 0% +19.15% (p=0.000 n=10)
```
The extra allocations are expected in the truncation path because
truncated `MAP` values are rebuilt recursively.
`benchstat` for `BenchmarkSpanLimits/AttributeValueLengthLimit`
(`count=10`):
```
SpanLimits/None-20 14.18µ ± 7% 12.86µ ± 18% -9.31% (p=0.043 n=10)
SpanLimits/None-20 12.16Ki ± 0% 12.16Ki ± 0% ~ (p=1.000 n=10)
SpanLimits/None-20 38.00 ± 0% 38.00 ± 0% ~ (p=1.000 n
```
No extra allocations where nothing needs to be rebuild.

Fixes #8400 .
Remap computed hash of 0 to 1 for non-empty input in hashKVs to prevent
zero-hash collapse to empty set. Do this instead of trying to handle the
actual hash of 0 because we use 0 in Distinct.IsValid()

Add WithUnsafeAttributes to support no-copy dynamic metric API calls ( #8251 )
...
Split from https://github.com/open-telemetry/opentelemetry-go/pull/8179
Part of https://github.com/open-telemetry/opentelemetry-go/issues/7743
This just defines the new WithUnsafeAttributes option, but converts it
to a set, and leaves the optimization of that path for a follow-up.

sdk/metric: reuse cumulative-histogram Collect buffers to reduce heap usage ( #8428 )
...
`cumulativeHistogram.collect()` was allocating a fresh `[]uint64` for
every series' `BucketCounts` (and a fresh `Exemplars` slice) on every
cycle. The delta path already reused these buffers; the cumulative path
now follows the same pattern: pre-size `h.DataPoints`, write in place so
`loadCountsInto` and `collectExemplars` reuse the existing slot's
capacity, and explicitly clear `Sum`/`Min`/`Max` since `sync.Map`
iteration order isn't stable across cycles.
Steady-state allocation at high cardinality drops by ~98% (187 MiB ->
3.8 MiB per cycle at 100k series).
Fixes #8427

fix: off-by-one bug for FixedSizeReservoir ( #8309 )
...
While working on
https://github.com/open-telemetry/opentelemetry-go/pull/8306 , I found an
off-by-one error.
Reset was setting `r.next` to `k`, and then calling advance(), which
meant `r.next` was always at least `k+1`.
The first `k` exemplars are unconditionally stored during the "fill"
phase. Count is incremented at the end of the Offer call, so the `k+1`th
exemplar was **never** stored because `r.next` is `k` when that Offer
call is being evaluated.

Cleanup limitedSyncMap, and add tests ( #8302 )
...
Making some cleanups to the existing limitedSyncMap before
https://github.com/open-telemetry/opentelemetry-go/pull/8276 .
### Changes
limitedSyncMap uses generics to eliminate the need to use type
assertions in the aggregators themselves, and moves all type assertions
to be internal to the limitedSyncMap implementation
Testing
* Added two new tests for limitedSyncMap: a ConcurrentSafe test, and a
test that ensures the overflow limit is correctly enforced after it is
Cleared.

sdk/trace: avoid logging exporter endpoint configuration ( #8438 )
...
Prevent internal trace exporter logging from including endpoint
configuration.
`MarshalLog` now keeps the existing log shape where practical, but logs
exporter/client type strings instead of recursively serializing exporter
and client internals. OTLP trace HTTP/gRPC and Zipkin exporter log
payloads no longer include endpoint URLs, embedded credentials, query
tokens, internal hostnames, or insecure transport configuration.
## Changes
- Stop recursive logging of trace exporter/client config from
`sdk/trace` span processors and `otlptrace.Exporter`.
- Remove endpoint/URL fields from OTLP trace HTTP/gRPC and Zipkin
`MarshalLog` output.
- Add regression coverage for credential-bearing endpoints not appearing
in internal log output.

When `ExportOp.End` is called with a non-nil error and `exportedSpans`
metric is disabled but `opDuration` is enabled, the `error.type`
attribute is not included in the duration histogram record.
