SQLx Cache Generation Required
Prerequisites
- ✅ Code changes applied by Agent 159
- ⏳ PostgreSQL database running (localhost:5432)
- ⏳ Database contains PostgreSQL functions:
get_top_models_24h(symbol text, limit integer)get_high_disagreement_events_24h(symbol text, threshold double precision, limit integer)
Commands for Group E
# 1. Verify database connectivity
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt -c "SELECT 1"
# 2. Verify PostgreSQL functions exist
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt -c "\df get_top_models_24h"
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt -c "\df get_high_disagreement_events_24h"
# 3. Generate SQLx cache (requires SQLX_OFFLINE=false)
cd /home/jgrusewski/Work/foxhunt
SQLX_OFFLINE=false cargo sqlx prepare --package trading_service
# 4. Verify cache files created
ls -la services/trading_service/.sqlx/*.json | tail -5
# 5. Build with offline mode
SQLX_OFFLINE=true cargo check -p trading_service
# 6. Verify no errors
echo $? # Should be 0 for success
Expected Outcomes
Before Agent 159 Fixes
error: `SQLX_OFFLINE=true` but there is no cached data for this query
--> services/trading_service/src/ensemble_audit_logger.rs:530
|
| SELECT * FROM get_top_models_24h($1, $2)
|
error: `SQLX_OFFLINE=true` but there is no cached data for this query
--> services/trading_service/src/ensemble_audit_logger.rs:551
|
| SELECT * FROM get_high_disagreement_events_24h($1, $2, $3)
|
Total errors: 4 (including INSERT queries)
After Agent 159 Fixes + SQLx Cache
cargo check -p trading_service
Expected Output:
Checking trading_service v1.0.0 (/home/jgrusewski/Work/foxhunt/services/trading_service)
Finished `dev` profile [unoptimized + debuginfo] target(s) in X.XXs
Exit Code: 0 (success)
Rollback Plan (If Issues Found)
If Column Mismatch Errors
# Revert changes
git diff services/trading_service/src/ensemble_audit_logger.rs
git checkout -- services/trading_service/src/ensemble_audit_logger.rs
# Report to Agent 159 for correction
If PostgreSQL Functions Missing
# Check migration status
cargo sqlx migrate run
# Or manually create functions (if not in migrations)
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt < migrations/XXX_create_analytics_functions.sql
If Database Unavailable
# Start PostgreSQL container
docker-compose up -d postgres
# Wait for healthy status
docker-compose ps postgres
Success Criteria
✅ All criteria must pass:
- ✅ Code changes applied (Agent 159 complete)
- ⏳ SQLx cache generated (
cargo sqlx preparesucceeds) - ⏳ Compilation succeeds (
cargo check -p trading_serviceexit 0) - ⏳ No type mismatch errors (struct fields match query columns)
- ⏳ Integration tests pass (if applicable)
Error Resolution Guide
Error: "function get_top_models_24h does not exist"
Solution: Run database migrations
cargo sqlx migrate run
Error: "column count mismatch"
Solution: Verify struct matches query (see validation sections above)
Error: "type mismatch for column X"
Solution: Check PostgreSQL function return type vs Rust struct type
psql postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt -c "\df+ get_top_models_24h"
