libdatadog Integration Report

libdatadog SHA: 98016adb6ea73454ea4804a3847724d7b215b677
Analysis date: 2026-06-06

Overall status

✅ Clean update

No code changes were required. The new libdatadog revision is a release
version-bump merge with no functional/API changes, and all compilation jobs
passed. The three failing jobs are runtime test failures (Windows hangs and one
ASAN test) that cannot be attributed to this libdatadog update.

Build & test summary

The only new libdatadog commit since the pinned SHA is:

98016adb6 chore(release): merge release branch to main (proposal for libdd-sampling (#2087)) (#2089)

The net diff this merge introduces to main touches no Rust source files —
only version metadata:

Cargo.lock
libdd-data-pipeline/Cargo.toml
libdd-sampling/Cargo.toml         (-> 3.0.0)
libdd-sampling/CHANGELOG.md
libdd-trace-obfuscation/Cargo.toml
libdd-trace-stats/Cargo.toml
libdd-trace-utils/Cargo.toml
libdd-trace-utils/CHANGELOG.md
libdd-tracer-flare/Cargo.toml

These are crate version bumps (e.g. libdd-sampling 2.1.0 → 3.0.0) and
changelog entries that were already present in the source tree dd-trace-php was
building against; the merge simply lands them on main. There is no API
surface change, no signature change, and no behavioural change in this delta.

Sub-pipeline results:

Sub-pipeline	Result
package-trigger	✅ success
appsec-trigger	✅ success
profiler-trigger	✅ success
shared-trigger	✅ success
tracer-trigger	❌ failed (3 test jobs, below)

All Rust/native build steps compiled and linked successfully against the new
libdatadog (every build/package job passed, and the compilation-trace directory
tmp/artifacts/traces/ is empty — the harness captured no compilation
failures). The three failures are all in the test stage, not the build stage.

Non-trivial changes made

No code changes required.

Identified libdatadog issues

None identified.

The libdatadog delta is version metadata only (no .rs changes), so none of the
observed failures can originate from a libdatadog code change.

Flaky / ignored failures

All three failing jobs are in the tracer test stage and are unrelated to the
(metadata-only) libdatadog update:

1. windows test_c: [7.3] — failure_reason: job_execution_timeout.
   The job ran for the full ~3602s (1-hour) job limit and was killed, i.e. it
   hung rather than failing a specific assertion. Windows runners are prone to
   this class of hang/timeout. No build output or compilation failure precedes
   it.

2. windows test_c: [7.2] — failure_reason: job_execution_timeout.
   Same signature as the 7.3 job: ran the full ~3602s and timed out. Two
   simultaneous Windows-only timeouts on the same runner group point at runner
   infrastructure / a flaky hang, not at a libdatadog change (which contains no
   code).

3. ASAN test_c with multiple observers: [8.4] — failure_reason: script_failure after ~286s. This is the Linux ASAN variant of the C test
   suite under the multiple-observers configuration. Because the libdatadog
   delta introduces no functional code, this failure is not attributable to the
   update; it is treated as pre-existing flakiness/infra noise. (Full job logs
   were not available in the artifacts — only all_failures.json metadata and a
   junit archive that was not extracted — so no specific assertion could be
   correlated; the version-only nature of the libdatadog change is sufficient to
   exclude it as a cause.)

These same three jobs are the ones the CI harness already retried
(tmp/artifacts/retried_jobs.tsv), consistent with transient/flaky behaviour.
