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

  1. Read the joined errors in order: the first is the original cause, the second is the rollback failure; fix both conditions
  2. Manually reconcile affected generated files (compare against templates or git) since automatic rollback did not complete
  3. 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

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.
