DB migration failure at startup panicked via .expect() (main.rs:223),
dumping a raw backtrace for what is usually just "PostgreSQL isn't running
yet". Worse, the 1.6s runtime retry budget was reused at startup, so it
almost always failed against a cold/slow DB (docker-compose without
healthchecks, local Postgres not started, etc.).
Changes:
- pool: extract build_pg_config() (returns Result, no panic); add
validate_database_url() so URL-format / DB_POOL_SIZE errors surface as
friendly exit(1) instead of hitting the LazyLock's unreachable .expect()
- pool: add get_conn_for_startup() — a startup-only retry loop with a
configurable total-duration window (MIGRATE_STARTUP_TIMEOUT_SECS,
default 30s, 500ms interval), separate from the runtime get_conn()
anti-avalanche fast retry (untouched)
- migrate: split run() into run_on_conn(&mut conn) so callers control the
connection-acquisition strategy; main.rs pairs this with the startup
retry. Advisory-lock release comment updated: exit(1) terminates the
process just like panic, so the session-level lock is still freed
- main: startup fatal errors (bad URL, DB unreachable, migration failed)
now each emit tracing::error! + eprintln! ERROR + targeted HINT, then
exit(1) — no panic, no backtrace nudge
- .env.example / AGENTS.md: document MIGRATE_STARTUP_TIMEOUT_SECS
No runtime behavior change: get_conn() and its ~40 call sites are
unchanged. Advisory-lock safety preserved (documented in migrate.rs).
- COMPRESSION_ALGORITHMS defaults to 'all' when unset
- Support 'none'/'off' to explicitly disable compression
- Add parse_compression_algorithms helper and unit tests
- Update .env.example comment to reflect new default
- Cache ammonia::Builder with LazyLock (was rebuilt per request)
- Enable tracing release_max_level_info to strip tracing overhead at compile time
- Remove TraceLayer and tower-http trace feature from production
- Increase DB pool size 10→20 (configurable via DB_POOL_SIZE)
- Increase SSR cache TTL 300s→3600s (configurable via SSR_CACHE_SECS)
Benchmark: 7,444 → 9,840 req/s, P99 latency 27.6ms → 11.1ms
- Replace image crate's WebP with zenwebp for better quality/speed
- Add webp.rs module with configurable quality and method
- Update .env.example with WEBP_QUALITY and WEBP_METHOD
- Add WebP decode support in image serving pipeline
- Add detailed timing logs for WebP conversion
- Separate /uploads and /api/upload routes from Dioxus app to avoid
IncrementalRenderer intercepting non-page requests
- Remove broken SmartIpKeyExtractor-based general_limit() that failed
under Dioxus dev server proxy (Unable To Extract Key)
