Johnny db57f4456a fix: resolve data races in store tests with atomic operations
Fix all data races detected by -race flag in parallel store tests.

Problems fixed:
1. TestMain not propagating exit code
   - Was: m.Run(); return
   - Now: os.Exit(m.Run())

2. Data races on global DSN variables
   - mysqlBaseDSN and postgresBaseDSN written in sync.Once
   - Read outside Once without synchronization
   - Race detector: write/read without happens-before relationship

3. Data races on container pointers
   - mysqlContainer, postgresContainer, testDockerNetwork
   - Same pattern: write in Once, read in cleanup

Solution: Use atomic operations
- atomic.Value for DSN strings (Store/Load)
- atomic.Pointer for container pointers (Store/Load)
- Provides proper memory synchronization
- Race-free reads and writes

Why sync.Once alone wasn't enough:
- sync.Once guarantees function runs once
- Does NOT provide memory barrier for variables written inside
- Reads outside Once have no synchronization with writes
- Race detector correctly flags this as violation

Technical details:
- atomic.Value.Store() provides release semantics
- atomic.Value.Load() provides acquire semantics
- Guarantees happens-before relationship per Go memory model
- All 159 parallel tests can safely access globals

Impact:
- Tests now pass with -race flag
- No performance degradation (atomic ops are fast)
- Maintains parallel execution benefits (8-10x speedup)
- Proper Go memory model compliance

Store tests

How to test store with MySQL?

  1. Create a database in your MySQL server.
  2. Run the following command with two environment variables set:
DRIVER=mysql DSN=root@/memos_test go test -v ./test/store/...
  • DRIVER should be set to mysql.
  • DSN should be set to the DSN of your MySQL server.
