剛剛追了一下walkor的源碼, 發(fā)現(xiàn)校驗文件熱重啟的邏輯只是對比了一下文件的最后更新時間, 這個并不包括 文件的新增, 改名, 刪除等邏輯, 如果要想實現(xiàn)相應的邏輯, 需要自行調整代碼

public function checkFilesChange($monitorDir): bool
    {
        static $lastMtime, $tooManyFilesCheck;
        if (!$lastMtime) {
            $lastMtime = time();
        }
        clearstatcache();
        if (!is_dir($monitorDir)) {
            if (!is_file($monitorDir)) {
                return false;
            }
            $iterator = [new SplFileInfo($monitorDir)];
        } else {
            // recursive traversal directory
            $dirIterator = new RecursiveDirectoryIterator($monitorDir, FilesystemIterator::SKIP_DOTS | FilesystemIterator::FOLLOW_SYMLINKS);
            $iterator = new RecursiveIteratorIterator($dirIterator);
        }

                continue;
            }
            // check mtime 主要這里校驗了最后一次更新的時間

                $lastMtime = $file->getMTime();
                if (DIRECTORY_SEPARATOR === '/' && isset($this->loadedFiles[$file->getRealPath()])) {
                    echo "$file updated but cannot be reloaded because only auto-loaded files support reload.\n";
