删除新建文件 失败

Error message

删除新建文件 %s 失败: %w

What it means

When rolling back a file that did not exist before the task (file.Existed == false), rollback deletes it. If os.Remove fails with any error other than ErrNotExist, the removal failed and rollback aborts with this wrapped error naming the path.

Solutions

1. Fix permissions on the file and its parent directory so the server process can delete it (chown/chmod or run as the owning user)
2. Close programs holding the file open (editors, `go run`, nodemon/vite watchers) and retry
3. Check that the path is still a regular file, not a directory, and remove the intruding entry manually
4. On Windows, ensure the file isn't read-only (clear the read-only attribute)

Example fix

// before
-rw-r--r-- 1 root root api.go   # server runs as www-data
// after
sudo chown www-data:www-data server/api/v1/api.go

if err := unix.Access(dir, unix.W_OK); err != nil {
    return fmt.Errorf("cannot delete in %s: %w", dir, err)
}
// and verify target is a regular file
st, err := os.Stat(targetPath)
if err == nil && !st.Mode().IsRegular() {
    return fmt.Errorf("%s is not a regular file", targetPath)
}

if err := commitAutoCodeFileTask(task, publish, persist); err != nil {
    if strings.Contains(err.Error(), "删除新建文件") {
        var path string
        fmt.Sscanf(err.Error(), "删除新建文件 %s 失败", &path)
        fmt.Printf("manually remove %s after fixing permissions\n", path)
    }
}

When it happens

Trigger: os.Remove(newFile) returns a real error during rollback — typically EACCES/EPERM (file or containing directory not writable by the process), EBUSY (file held open/locked on Windows), or the path turned into a directory.

Common situations: Server process lacks write permission on the generated directory (e.g. root-created files, read-only mount), Windows locks the file while a watcher/editor has it open, or the target was replaced by a directory between apply and rollback.
