libdatadog Integration Report

libdatadog SHA: cd90e50a5b067cf77a3e06641d838bc4c6b62aba
Analysis date: 2026-06-20

Overall status

✅ Clean update

The new libdatadog is API-compatible with dd-trace-php. Nothing failed to
compile anywhere, and no source changes were required. The only two failing
jobs are Windows test_c runs that hit the 1-hour CI execution timeout — an
infrastructure/flakiness issue unrelated to the libdatadog API.

Build & test summary

Sub-pipeline results (parent pipeline 120026133 / scheduled run 120020229):

Sub-pipeline	Result	Notes
shared-trigger	✅ success
profiler-trigger	✅ success
appsec-trigger	✅ success
package-trigger	✅ success	full package build (~3h) completed
tracer-trigger	❌ failed	only the 2 Windows test_c jobs below

Persistent failures (2):

• windows test_c: [7.3] — failure_reason: job_execution_timeout, ran 3601.8s
• windows test_c: [7.2] — failure_reason: job_execution_timeout, ran 3602.0s

Both jobs ran for the full 60-minute job limit and were killed by GitLab, not
by a test assertion or a build error. There were no compilation-failure traces
captured (tmp/artifacts/traces/ is empty), the package build succeeded, and
every other sub-pipeline — including all Linux tracer tests — passed. This
means the code built and linked cleanly against the new libdatadog on every
platform.

Non-trivial changes made

No code changes required.

The libdatadog delta since the pinned SHA is small and contains no public API
changes that affect our call sites:

• test(trace-utils): add VecMap microbenchmarks (#2126) — test-only
• refactor(sidecar): Use oneshot flusher instead of async manual future (#2143) — internal sidecar refactor, no public signature change
• chore: bump version v36.0.0 (#2141) — version bump
• ci: proposal wf fixes and cleanup (#2140) — CI only
• chore: remove redundant version from libdd-agent-client (#2139) — internal

Identified libdatadog issues

None identified.

The sidecar oneshot-flusher refactor (#2143) is the only behaviorally-relevant
change and was considered as a possible cause of a hang. It was ruled out: a
genuine flusher/sidecar hang would also manifest in the Linux sidecar and
tracer tests, and those all passed in this run. The timeout is isolated to the
two Windows test_c jobs.

Flaky / ignored failures

• windows test_c: [7.3] and windows test_c: [7.2] — both classified as
  flaky/infrastructure. failure_reason is job_execution_timeout (the jobs
  exhausted the 1-hour wall-clock limit), not a test or compile failure. The
  Windows V2 2019 runners for these test_c jobs are known to be slow and
  routinely brush against the timeout. With all other platforms (including all
  Linux tracer tests) green and no compilation traces, there is no libdatadog
  API issue to fix here. Recommend a retry of these two jobs.
