Test Replicate compaction logic. This command helps test and debug compaction issues, especially with eventually consistent storage backends.
First, understand the test scenario:
- What storage backend needs testing?
- What size database is involved?
- Are there eventual consistency concerns?
Then create comprehensive tests:
- Test basic compaction:
func TestCompaction_Basic(t *testing.T) {
// Create multiple LTX files at level 0
// Run compaction to level 1
// Verify merged file is correct
}
- Test with eventual consistency:
func TestStore_CompactDB_RemotePartialRead(t *testing.T) {
// Use mock client that returns partial data initially
// Verify compaction prefers local files
// Ensure no corruption occurs
}
- Test lock page handling during compaction:
func TestCompaction_LockPage(t *testing.T) {
// Create database > 1GB
// Compact with data around lock page
// Verify lock page is skipped (page at 0x40000000)
}
- Test timestamp preservation:
func TestCompaction_PreserveTimestamps(t *testing.T) {
// Compact files with different CreatedAt times
// Verify earliest timestamp is preserved
}
Key areas to test:
- Reading from local files first (db.go:1280-1294)
- Skipping lock page at 1GB boundary
- Preserving CreatedAt timestamps
- Handling partial/incomplete remote files
- Concurrent compaction safety
Run with race detector:
go test -race -v -run TestStore_CompactDB ./...
Use the test harness for large databases:
./bin/replicate-test populate -db test.db -target-size 1.5GB
./bin/replicate-test validate -source-db test.db -replica-url file:///tmp/replica
