回滚自动代码文件失败: %w
Error message
回滚自动代码文件失败: %w
What it means
joinAutoCodeRollbackError combines the original commit failure with any rollback failure via errors.Join. When rollback itself failed, the returned error additionally carries 回滚自动代码文件失败 wrapping the rollback error — signaling the workspace may now be in a partially-applied, partially-reverted state. It is a wrapper, not a root cause; always inspect the sibling error(s) in the join for the primary failure.

Solutions
- Read the joined errors in order: the first is the original cause, the second is the rollback failure; fix both conditions
- Manually reconcile affected generated files (compare against templates or git) since automatic rollback did not complete
- Run the operation again from a clean tree (git checkout the generated paths) after removing the interfering watcher/editor/process
Example fix
// before: treating the wrapper as the cause
if strings.Contains(err.Error(), "回滚自动代码文件失败") { ... }
// after: unwrap the joined errors
for _, e := range errors.Errors(err) { log.Println(e) }
// or errors.Is(err, errAutoCodeFileConflict) Defensive patterns
Strategy: try-catch
Validate before calling
// no pre-check possible; handle the joined error after the call err := commitAutoCodeFileTask(task, publish, persist)
Try / catch
err := commitAutoCodeFileTask(task, publish, persist)
if err != nil {
if errors.Is(err, errAutoCodeFileConflict) {
// rollback was blocked by an external file change
}
if joined, ok := err.(interface{ Unwrap() []error }); ok {
for _, e := range joined.Unwrap() {
log.Printf("joined error: %v", e)
}
}
// reconcile workspace from git before retrying
git status --porcelain server/ web/
} Prevention
- Always inspect joined errors with errors.Is/errors.As, never substring matching on the wrapper
- Run generation from a clean git tree so partial states are recoverable
- Avoid external writers (watchers, formatters) during commitAutoCodeFileTask
- Treat this error as 'workspace may be inconsistent' — diff before continuing
When it happens
Trigger: Any failure inside commitAutoCodeFileTask (apply error, persist() DB error, frontend publish error) whose accompanying task.rollback(applied) also returns an error — e.g. rollback hit a file conflict or filesystem failure.
Common situations: DB commit failed AND a generated file was externally modified so rollback stopped mid-way; nested wrappers like 回滚失败 → 文件冲突 appear when errors.Is chains are printed.
