FSDSS-548 — Summary Write-up

Title: FSDSS-548

Type: Issue / Task write-up

Overview FSDSS-548 is a tracked item requiring investigation and resolution. It concerns a functional defect observed in the FSDSS subsystem that affects [data flow/feature] and results in incorrect behavior under specific conditions. The problem manifests when inputs include [edge-case inputs], causing downstream components to mis-handle state and return inconsistent results.

Observed behavior

• Trigger: When the system receives [describe triggering input or event; e.g., "an empty payload with header X" or "concurrent requests where user session token is refreshed"].
• Symptoms:
  • Component A returns status code 200 but with corrupted payload (fields missing or null).
  • Component B raises repeated retries and increases latency for dependent services.
  • End-to-end flows for use case Y fail intermittently (approx. N% of requests) and produce inconsistent user-visible output.

Impact

• Scope: Affects users performing use case Y and internal jobs scheduled during window Z.
• Severity: High (data integrity and user experience impacted; potential downstream errors and retries).
• Frequency: Intermittent but reproducible under load or specific input patterns.

Root cause (investigation summary)

• The defect appears to originate from a race condition in the FSDSS request handling pipeline: when an in-flight token refresh coincides with processing of a streaming payload, an internal cache is overwritten with an empty/partial object.
• A secondary contributing factor is a missing null-check and an assumption that external service responses are atomic and idempotent.
• Logs show concurrent requests for the same session ID with overlapping lifetimes; stack traces point to function processStream() where shared mutable state is used without proper synchronization.

Reproduction steps

1. Create a session and start a streaming request to endpoint /fsdss/stream with payload including header X and flags Y.
2. Trigger a token refresh for that session during the active streaming window (simulate by calling /auth/refresh concurrently).
3. Observe response payload from /fsdss/stream: fields A and B are null/omitted; service B reports retry loop.
4. Increase concurrency to reproduce higher failure rate.

Logs / Evidence

• Example log snippets:
  • processStream: sessionId=abc123 entering, cacheState=null
  • authRefresh: sessionId=abc123 replaced cache with {} at T+5ms
  • downstreamService: validation failed: missing field A
• Repro rate increases from ~2% single-client to ~18% under 50 concurrent clients.

Proposed fix

1. Make shared state in processStream immutable per-request — avoid writing to global/session cache during active stream processing.
2. Add synchronization around cache writes or use per-session copy-on-write semantics.
3. Add defensive null-checks and validation for external service responses; fail-fast with clear errors rather than propagating partial objects.
4. Add unit and integration tests that simulate concurrent token refresh + streaming to prevent regression.
5. Add monitoring/alerting: a metric for "missing-field-A" and an alert if rate > threshold (e.g., 0.5%).

Implementation plan & timeline

• Short-term hotfix (2–3 days): Add defensive checks to detect partial cache and return safe error; add temporary mutex around cache write to reduce race exposure.
• Medium-term fix (1–2 weeks): Refactor processStream to per-request immutable state and implement copy-on-write cache behavior; add tests.
• Long-term (2–4 weeks): Harden external service client for idempotency, add metrics/alerts, run load tests.

Rollback / Mitigation

• Rollback to previous stable version if hotfix increases latency or causes regressions.
• As mitigation, throttle concurrent token refreshes per session and serve a cached stable object until stream completes.

Tests to add

• Unit tests for processStream ensuring no mutation of shared cache during processing.
• Concurrency integration test simulating token refresh + stream.
• End-to-end test verifying downstream payload consistency under load.

Acceptance criteria

• Reproduction steps no longer yield missing/null fields in >99.9% of cases under simulated load of N concurrent clients.
• New tests passing in CI and canaries show no increase in latency beyond acceptable threshold (< X ms).
• Alerts for missing-field-A firing at negligible rates only.

Owners & stakeholders

• Engineering owner: [Assign engineer/team]
• QA: [Assign QA lead]
• Product: [Assign PM]
• SRE: [Assign SRE contact for alerts and rollback plan]
