机器上发生了无法解析的错误，导致无法检测fps相关，请见日志 #61

Closed icesword0760 closed 2 years ago

icesword0760 commented 2 years ago

我修改了源码用于打印出需要解析的字节，检测fps相关时，程序会无法正常工作，报错类型为 无法解析 修改的方法：
def check_header(self,kd_buf): print(kd_buf) if kd_buf.startswith(b'\x07X\xa2Y'): return io.BytesIO() buf_io = io.BytesIO(kd_buf) if not self.threads_pids: self.version = buf_io.read(4) print(buf_io.read()) parsed_header = kd_header_v2.parse_stream(buf_io) self.set_threads_pids(parsed_header.threadmap) return buf_io

现在这个库fps相关功能完全无法使用，希望可以尽快解决，非常感谢

YueChen-C commented 2 years ago

如果仅仅是解析 fps 建议 用 kperf_data 来解析 而不是 Kperf.to_dict这里应该早就做了兼容处理，最新的代码应该不会有这个问题。 还有如果可以的话在这里帮我保存个 res.selector.data 一些数据给我吗 for args in Kperf.to_dict(res.selector.data):

icesword0760 commented 2 years ago

可以的 你的这行代码我要插在哪里（文件路径，代码行数）？需要在最新的版本上插入吗还是我当前这个版本

这是你的文件路径 最近版本这个问题应该解决了，但我想你帮我在一个文件里保存一下这里的二进制数据包，因为这涉及 Kperf.to_dict 解析，我想看看哪里报错了

你这没更新成功吧 Kperf.to_dict 应该 变成了 kperf_data 方法，你加 qq 群然后加我交流吧
