SQLx Cache Generation Required

Prerequisites

  1. Code changes applied by Agent 159
  2. PostgreSQL database running (localhost:5432)
  3. 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:

  1. Code changes applied (Agent 159 complete)
  2. SQLx cache generated (cargo sqlx prepare succeeds)
  3. Compilation succeeds (cargo check -p trading_service exit 0)
  4. No type mismatch errors (struct fields match query columns)
  5. 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"
