python - Esky更新导致事务处理文件操作错误

Question

这是我运行 esky auto_update 时遇到的错误:

Traceback (most recent call last):
File "__main__.py", line 838, in <module>
File "__main__.py", line 331, in bootstrap
File "__main__.py", line 358, in chainload

File "esky\fstransact\win32txf.pyc", line 24, in wrapper
WindowsError: [Error 6805] The remote server or share does not support transacted file operations.

在服务器上，我看到更新请求两次。

这可能是一个网络问题，因为该问题不会发生在本地网络上，而是仅在从远程站点更新时发生。关于出了什么问题以及如何解决这个问题有什么想法吗？

Answer 1

Esky 使用事务性 NTFS 在移动文件时保持数据完整性，特别是 MoveFileTransacted功能。但是，事务性 NTFS 仅适用于本地文件。

引用 Microsoft 文档，When to Use Transactional NTFS :

TxF does not support the following transaction scenarios:

• Transactions on network volumes, for example on file shares. TxF is not supported by the CIFS/SMB protocols.
• Transactions on any file system other than NTFS.
• Transacted operations against files cached by client-side caching.
• File access using object IDs.
• Any shared writer scenario.
• Any situation where a file is opened for an extended period of time (days or weeks).

除了不远程更新之外，我不确定还有什么方法可以解决这个问题。
