我在从 pyinotify 捕获事件处理程序中的错误时遇到问题。我正在尝试对写入后刚刚关闭的文件进行一些处理。

这是我的脚本的简化版本:

import pyinotify
import asyncore

mask = pyinotify.IN_CLOSE_WRITE

class EventHandler(pyinotify.ProcessEvent):

    def process_IN_CLOSE_WRITE(self, event):
        try:
            do_stuff()
        except BaseException as e:
            print "Exception:" + str(e)
            pass

if __name__ == "__main__":
        try:
                wm = pyinotify.WatchManager()

                notifier = pyinotify.AsyncNotifier(wm, EventHandler())
                wdd = wm.add_watch('/dir-to-watch/', mask, rec=True)
                asyncore.loop()
        except:
                print "Unhandled error!"
                print "Details:" + str(e)
                print "Continuing anyway..."
                pass

似乎当我收到错误或异常时,主循环中的异常或事件处理程序中的异常BaseException没有捕获错误或异常。

我收到这样开头的消息:

错误:未捕获的python异常,关闭通道(:[Errno 2]没有这样的文件或目录:

所以我的问题是:如何捕捉这些异常?

I had to create a custom AsyncNotifier:

class CustomAsyncNotifier(pyinotify.AsyncNotifier):
        def handle_error(self):
                print "Handling error!"
                print "Guru meditiation #00000025.65045338"
                print ""
                print "Continuing anyway..."

and then change my code to use it:

if __name__ == "__main__":
        wm = pyinotify.WatchManager()

        notifier = CustomAsyncNotifier(wm, EventHandler())
        wdd = wm.add_watch('/mnt/md0/proxies/', mask, rec=True)
        asyncore.loop()
