Syncserver Jira Description
Draft a Jira description for a syncstorage-rs task. Output the description only — do not create, edit, or suggest changes to any source files.
Step 1: Gather context
If a planning doc, epic description, or tech spec was provided, read it first and infer what, why, crates, and constraints before asking anything.
Required information:
- What: What is being built or changed, in one sentence
- Why: Motivation — user need, requirement, bug, or tech debt
- Crates: Which specific crate(s) will be modified (e.g.
syncstorage-spanner, tokenserver-auth, syncserver, tokenserver-postgres)
- Constraints: DB migration required, multi-backend impact (MySQL/Postgres/Spanner), breaking API change, feature flag, FxA contract change — or none
If all four are clear from provided context, proceed directly to Step 2. Otherwise ask for only what is missing in a single message. Also invite related PRs, tickets, existing approach notes, or architecture notes that would add useful context.
Step 2: Research
Search only the crates identified in Step 1. Find the most relevant existing patterns: similar feature, nearby handler, equivalent DB query, related error type. Expand to the broader workspace only if nothing relevant is found there.
Identify:
- Key files an implementer will need to touch
- The closest existing reference implementation to follow
- Which database backends are affected and whether the change must be replicated across MySQL, PostgreSQL, and/or Spanner
- Whether new migrations are required (and which crates:
syncstorage-mysql, syncstorage-postgres, tokenserver-mysql, tokenserver-postgres)
- Whether tests, metrics (Glean/StatsD), or Sentry error handling apply
Incorporate findings directly into the draft — do not list them separately or ask for confirmation. Surface genuine blockers as Open Questions.
Step 3: Output
Background:
Why this is needed and what it enables. 2–4 sentences. Note which service is affected — Syncstorage (storage node), Tokenserver (node allocation + FxA auth), or both.
Acceptance Criteria:
Observable, testable outcomes. Each item verifiable without reading the code. Include criteria for tests, metrics emission, and Sentry error classification where applicable.
Implementation Steps:
Numbered steps with crate paths, file paths, trait/function names, and structural guidance. Reference the nearest existing pattern for each step. For multi-backend changes, call out which backends need matching implementations. No code snippets — file locations, types, and patterns only.
Database Migrations: (omit if no schema changes)
Which migration crates need new files (syncstorage-mysql/migrations/, tokenserver-postgres/migrations/, etc.). Reminder: never edit published migrations — add new up.sql/down.sql pairs only.
Tests:
What needs to be tested. Unit (#[cfg(test)] in the relevant crate), integration (tools/integration_tests/ pytest — requires running server), and E2E (tokenserver/test_e2e.py — hits FxA staging, session-scoped) coverage expectations. Reference the nearest existing test file as a pattern.
Metrics & Error Handling: (omit if not applicable)
Any Glean metrics, StatsD counters, or Sentry event classifications that should be emitted or updated. Note whether new error variants should be routed to Sentry or suppressed as metrics (see is_sentry_event() pattern in syncstorage-spanner/src/error.rs).
Key Reference Files:
Specific files the implementer should read before starting. One line each.
Out of Scope: (omit if not needed)
Open Questions: (omit if none)
Guidelines
- Output the description only — no source file changes
- Implementation Steps should give enough detail to start work without follow-up questions — crate paths, file paths, and patterns, not prose
- Multi-backend tasks: always explicitly name which backends (MySQL / PostgreSQL / Spanner) need matching changes; do not say "all backends" without listing them
- Migration tasks: always reference the no-edit-published-migrations rule
- Omit redundant or obvious acceptance criteria
- Include Database Migrations, Metrics & Error Handling only when relevant
- If motivation or scope remain unclear after asking, flag as an Open Question rather than assuming
- Branch naming reminder for the assignee: Mozilla engineers use
type/description-STOR-####; community contributors use type/description-####
