python - 使用 pyinotify 监视文件创建，但等待它完全写入磁盘

Question

我正在使用 pyinotify 来监视文件夹以了解何时在其中创建文件。当创建某些文件时，我想移动它们。问题是文件一创建(很明显)，我的程序就会尝试移动它，甚至在它完全写入磁盘之前。

有没有办法让 pyinotify 等到文件完全写入磁盘后才通知我文件已创建？或者有什么简单的方法可以在我收到通知后让 python 等待移动它直到它完成写入？

让 pyinotify 对 IN_CLOSE_WRITE 使用react事件:

wm.add_watch(watched_dir, pyinotify.IN_CLOSE_WRITE, proc_fun=MyProcessEvent())

这来自 man 5 incrontab，但它同样适用于 pyinotify:

   IN_ACCESS           File was accessed (read) (*)
   IN_ATTRIB           Metadata changed (permissions, timestamps, extended attributes, etc.) (*)
   IN_CLOSE_WRITE      File opened for writing was closed (*)
   IN_CLOSE_NOWRITE    File not opened for writing was closed (*)
   IN_CREATE           File/directory created in watched directory (*)
   IN_DELETE           File/directory deleted from watched directory (*)
   IN_DELETE_SELF           Watched file/directory was itself deleted
   IN_MODIFY           File was modified (*)
   IN_MOVE_SELF        Watched file/directory was itself moved
   IN_MOVED_FROM       File moved out of watched directory (*)
   IN_MOVED_TO         File moved into watched directory (*)
   IN_OPEN             File was opened (*)
