## Prompts
|
||||
|
||||
### Prompt 1
|
||||
|
||||
Implement the following plan:
|
||||
|
||||
# Fix Missing `rows.Close()` Memory Leaks in SQLite3 Queries
|
||||
|
||||
## Context
|
||||
|
||||
Production memory leaks traced to queries that do full table scans (e.g., job state list sorted by `start_time` on all jobs). The root cause is `sql.Rows` objects not being closed after query execution. In Go's `database/sql`, every `rows` returned by `.Query()` holds a database connection and associated buffers until `rows.Close()` is called. Without `defer rows.Close()`, these leak on every code path (both success and error returns).
|
||||
|
||||
## Findings
|
||||
|
||||
**22 total `.Query()` calls** across the repository layer. **15 have `defer rows.Close()`**. **7 do not** (listed below). Additionally, 1 `Queryx` call in `tags.go` is also missing close.
|
||||
|
||||
In `node.go`, `QueryNodes` and `QueryNodesWithMeta` have partial `rows.Close()` only in error paths but **not on the success path** and not via `defer`.
|
||||
|
||||
`CountStates` and `CountStatesTimed` in `node.go` also lack `defer rows.Close()` (same partial pattern as above for CountStates, none at all for CountStatesTimed).
|
||||
|
||||
## Changes Required
|
||||
|
||||
### 1. `internal/repository/stats.go` — 6 functions missing `defer rows.Close()`
|
||||
|
||||
Add `defer rows.Close()` immediately after the `if err != nil` check for each:
|
||||
|
||||
| Line | Function |
|
||||
|------|----------|
|
||||
| 233 | `JobsStatsGrouped` |
|
||||
| 438 | `JobCountGrouped` |
|
||||
| 494 | `AddJobCountGrouped` |
|
||||
| 553 | `AddJobCount` |
|
||||
| 753 | `jobsStatisticsHistogram` |
|
||||
| 821 | `jobsDurationStatisticsHistogram` |
|
||||
| 946 | `jobsMetricStatisticsHistogram` |
|
||||
|
||||
Pattern — after each `Query()` error check, add:
|
||||
```go
|
||||
rows, err := query.RunWith(r.DB).Query()
|
||||
if err != nil {
|
||||
...
|
||||
return nil, err
|
||||
}
|
||||
defer rows.Close() // <-- ADD THIS
|
||||
```
|
||||
|
||||
### 2. `internal/repository/tags.go` — 2 leaks in `CountTags()`
|
||||
|
||||
**Line 282**: `xrows` from `r.DB.Queryx(...)` — add `defer xrows.Close()` after error check.
|
||||
|
||||
**Line 333**: `rows` from `q.RunWith(r.stmtCache).Query()` — add `defer rows.Close()` after error check.
|
||||
|
||||
### 3. `internal/repository/tags.go` — 3 leaks in `GetTags`, `GetTagsDirect`, `getArchiveTags`
|
||||
|
||||
**Line 508** (`GetTags`): add `defer rows.Close()` after error check.
|
||||
**Line 541** (`GetTagsDirect`): add `defer rows.Close()` after error check.
|
||||
**Line 579** (`getArchiveTags`): add `defer rows.Close()` after error check.
|
||||
|
||||
### 4. `internal/repository/node.go` — 4 functions missing `defer rows.Close()`
|
||||
|
||||
**Line 363** (`QueryNodes`): Replace the manual `rows.Close()` in the error path with `defer rows.Close()` immediately after the error check. Remove the explicit `rows.Close()` call on line 375.
|
||||
|
||||
**Line 412** (`QueryNodesWithMeta`): Same pattern — add `defer rows.Close()` after error check, remove explicit `rows.Close()` on line 427.
|
||||
|
||||
**Line 558** (`CountStates`): Add `defer rows.Close()` after error check. Remove explicit `rows.Close()` on line 569.
|
||||
|
||||
**Line 620** (`CountStatesTimed`): Add `defer rows.Close()` after error check. Remove explicit `rows.Close()` on line 633.

## Verification
|
||||
|
||||
1. `go build ./...` — ensure it compiles
|
||||
2. `go test ./internal/repository/...` — run repository tests
|
||||
3. `go vet ./internal/repository/...` — static analysis

## Summary
|
||||
|
||||
All changes are already in place and verified:
|
||||
All clean. Here's a summary of what was wrong and fixed in `node.go`:
|
||||
|
||||
- **Build**: passes
|
||||
- **go vet**: passes
|
||||
- **Tests**: pass
|
||||
|
||||
The changes are currently unstaged. All 16 locations from the plan have been fixed — `defer rows.Close()` added after each `Query()` error check, manual `rows.Close()` calls in error paths removed, and `rows.Err()` checks added where missing. The `AddJobCount` function was also simplified from `Query` + loop to `QueryRow().Scan()` since it returns a single value.
|
||||
1. **Duplicate `QueryNodesWithMeta`** (lines 468-541): The old unfixed version was left in alongside the fixed version at line 391. Removed the duplicate.
|
||||
2. **`CountStates`**: Had both old code (manual `stateMap` counting without SQL `COUNT(*)`) and new code (SQL `COUNT(*) ... GROUP BY`) concatenated together. The second `rows.Next()` loop was dead code since the first loop already consumed all rows. Replaced with the correct version using `SELECT column, COUNT(*) ... GROUP BY column`.
|
||||
3. **`QueryNodes` line 376**: Leftover `rows.Close()` inside the scan error path (redundant with `defer`). Removed.
