Go Error Handling

Compatibility: errors.Is, errors.As, and %w wrapping require Go 1.13+; structured logging examples may use log/slog from Go 1.21+.

Resource Routing

scripts/check-errors.sh - Run when checking string-based error matching, bare error propagation, and log-and-return patterns.
scripts/check-errors-ast.go - Implementation helper invoked by check-errors.sh; patch this when changing error-flow analysis behavior.
references/ERROR-FLOW.md - Read when deciding where to handle, wrap, log, or return errors.
references/ERROR-TYPES.md - Read when choosing sentinel errors, typed errors, or opaque errors.
references/WRAPPING.md - Read when choosing %w versus %v or crossing package boundaries.

In Go, errors are values — they are created by code and consumed by code.

Choosing an Error Strategy

System boundary (RPC, IPC, storage)? → Wrap with %v to avoid leaking internals
Caller needs to match specific conditions? → Sentinel or typed error, wrap with %w
Caller just needs debugging context? → fmt.Errorf("...: %w", err)
Leaf function, no wrapping needed? → Return the error directly

Default: wrap with %w and place it at the end of the format string.

Core Rules

Never Return Concrete Error Types

Never return concrete error types from exported functions — a concrete nil pointer can become a non-nil interface:

// Bad: Concrete type can cause subtle bugs
func Bad() *os.PathError { /*...*/ }

// Good: Always return the error interface
func Good() error { /*...*/ }

Error Strings

Error strings should not be capitalized and should not end with punctuation. Exception: exported names, proper nouns, or acronyms.

// Bad
err := fmt.Errorf("Something bad happened.")

// Good
err := fmt.Errorf("something bad happened")

For displayed messages (logs, test failures, API responses), capitalization is appropriate.

Return Values on Error

When a function returns an error, callers must treat all non-error return values as unspecified unless explicitly documented.

Tip: Functions taking a context.Context should usually return an error so callers can determine if the context was cancelled.

Handling Errors

When encountering an error, make a deliberate choice — do not discard with _:

Handle immediately — address the error and continue
Return to caller — optionally wrapped with context
In exceptional cases — log.Fatal or panic

To intentionally ignore: add a comment explaining why.

n, _ := b.Write(p) // never returns a non-nil error

For related concurrent operations, use errgroup:

g, ctx := errgroup.WithContext(ctx)
g.Go(func() error { return task1(ctx) })
g.Go(func() error { return task2(ctx) })
if err := g.Wait(); err != nil { return err }

Avoid In-Band Errors

Don't return -1, nil, or empty string to signal errors. Use multiple returns:

// Bad: In-band error value
func Lookup(key string) int  // returns -1 for missing

// Good: Explicit error or ok value
func Lookup(key string) (string, bool)

This prevents callers from writing Parse(Lookup(key)) — it causes a compile-time error since Lookup(key) has 2 outputs.

Error Flow

Handle errors before normal code. Early returns keep the happy path unindented:

// Good: Error first, normal code unindented
if err != nil {
    return err
}
// normal code

Handle errors once — either log or return, never both:

Error encountered?
├─ Caller can act on it? → Return (with context via %w)
├─ Top of call chain? → Log and handle
└─ Neither? → Log at appropriate level, continue

Error Types

Advisory: Recommended best practice.

Caller needs to match?	Message type	Use
No	static	`errors.New("message")`
No	dynamic	`fmt.Errorf("msg: %v", val)`
Yes	static	`var ErrFoo = errors.New("...")`
Yes	dynamic	custom `error` type

Default: Wrap with fmt.Errorf("...: %w", err). Escalate to sentinels for errors.Is(), to custom types for errors.As().

Error Wrapping

Advisory: Recommended best practice.

Use %v: At system boundaries, for logging, to hide internal details
Use %w: To preserve error chain for errors.Is/errors.As

Key rules: Place %w at the end. Add context callers don't have. If annotation adds nothing, return err directly.

Validation: After implementing error handling, run bash scripts/check-errors.sh to detect common anti-patterns. Then run go vet ./... to catch additional issues.

Error naming: See go-naming when naming sentinel errors (ErrFoo) or custom error types
Testing errors: See go-testing when testing error semantics with errors.Is/errors.As or writing error-checking helpers
Panic handling: See go-defensive when deciding between panic and error returns, or writing recover guards
Guard clauses: See go-control-flow when structuring early-return error flow or reducing nesting
Logging decisions: See go-logging when choosing log levels, configuring structured logging, or deciding what context to include in log messages

# Go Error Handling

> Compatibility: `errors.Is`, `errors.As`, and `%w` wrapping require Go 1.13+; structured logging examples may use `log/slog` from Go 1.21+.

## Resource Routing

- `scripts/check-errors.sh` - Run when checking string-based error matching, bare error propagation, and log-and-return patterns.
- `scripts/check-errors-ast.go` - Implementation helper invoked by `check-errors.sh`; patch this when changing error-flow analysis behavior.
- `references/ERROR-FLOW.md` - Read when deciding where to handle, wrap, log, or return errors.
- `references/ERROR-TYPES.md` - Read when choosing sentinel errors, typed errors, or opaque errors.
- `references/WRAPPING.md` - Read when choosing `%w` versus `%v` or crossing package boundaries.

In Go, [errors are values](https://go.dev/blog/errors-are-values) — they are
created by code and consumed by code.

## Choosing an Error Strategy

1. System boundary (RPC, IPC, storage)? → Wrap with `%v` to avoid leaking internals
2. Caller needs to match specific conditions? → Sentinel or typed error, wrap with `%w`
3. Caller just needs debugging context? → `fmt.Errorf("...: %w", err)`
4. Leaf function, no wrapping needed? → Return the error directly

**Default**: wrap with `%w` and place it at the end of the format string.

## Core Rules

### Never Return Concrete Error Types

**Never return concrete error types from exported functions** — a concrete `nil`
pointer can become a non-nil interface:

```go
// Bad: Concrete type can cause subtle bugs
func Bad() *os.PathError { /*...*/ }

// Good: Always return the error interface
func Good() error { /*...*/ }
```

### Error Strings

Error strings should **not** be capitalized and should **not** end with
punctuation. Exception: exported names, proper nouns, or acronyms.

```go
// Bad
err := fmt.Errorf("Something bad happened.")

// Good
err := fmt.Errorf("something bad happened")
```

For displayed messages (logs, test failures, API responses), capitalization is
appropriate.

### Return Values on Error

When a function returns an error, callers must treat all non-error return values
as unspecified unless explicitly documented.

**Tip**: Functions taking a `context.Context` should usually return an `error`
so callers can determine if the context was cancelled.

---

## Handling Errors

When encountering an error, make a **deliberate choice** — do not discard
with `_`:

1. **Handle immediately** — address the error and continue
2. **Return to caller** — optionally wrapped with context
3. **In exceptional cases** — `log.Fatal` or `panic`

To intentionally ignore: add a comment explaining why.

```go
n, _ := b.Write(p) // never returns a non-nil error
```

For related concurrent operations, use
[`errgroup`](https://pkg.go.dev/golang.org/x/sync/errgroup):

```go
g, ctx := errgroup.WithContext(ctx)
g.Go(func() error { return task1(ctx) })
g.Go(func() error { return task2(ctx) })
if err := g.Wait(); err != nil { return err }
```

### Avoid In-Band Errors

Don't return `-1`, `nil`, or empty string to signal errors. Use multiple
returns:

```go
// Bad: In-band error value
func Lookup(key string) int  // returns -1 for missing

// Good: Explicit error or ok value
func Lookup(key string) (string, bool)
```

This prevents callers from writing `Parse(Lookup(key))` — it causes a
compile-time error since `Lookup(key)` has 2 outputs.

```

├─ Caller can act on it? → Return (with context via %w)
├─ Top of call chain? → Log and handle
└─ Neither? → Log at appropriate level, continue
```

## Error Types

> **Advisory**: Recommended best practice.

| Caller needs to match? | Message type | Use |
|------------------------|--------------|-----|
| No | static | `errors.New("message")` |
| No | dynamic | `fmt.Errorf("msg: %v", val)` |
| Yes | static | `var ErrFoo = errors.New("...")` |
| Yes | dynamic | custom `error` type |

**Default**: Wrap with `fmt.Errorf("...: %w", err)`. Escalate to sentinels for
`errors.Is()`, to custom types for `errors.As()`.
