Description

Returned status of copyFile and copyDirectory are ignored. It's OK most of the time.

if (srcStatus.isDirectory()) {
    copyDirectory(srcPath, dstPath);
} else {
    copyFile(srcPath, srcStatus.getLen(), dstPath);
}
	
return srcPath.equals(dstPath) || delete(srcPath, true);

However, oss fs can not catch errors when rename from one dir to another if the src dir is being deleted. 

 

Another improvement is logging optimization. Changing log level to debug.
