![]() Obviously, if you haven’t done so already, you’ll need to install the boto3 package.I have a FileSystemWatcher monitoring a file on a network share. If an event occurs to make the share unavailable, maybe due to a network problem, the FileSystemWatcher becomes disconnected. An error occurs when a File Watch Task step fails. I can try handling the "Error" event, but based on MSDN documentation, this event is not related to the FileSystemWatcher becoming unattached. You can choose from the following options: Select Ignore to ignore the error and move to the next step. The "Error" event is related to FileSystemWatcher receiving too many notifications in a short period of timeĬausing an internal buffer overflow. To be hot-pluggable, so let's mark it with user_creatable = false.ĭiff -git a/hw/ide/microdrive.c b/hw/ide/microdrive.From MSDN documentation and testing, I can deduce the "Error" event may be raised as a result of the FileSystemWatcher becoming disconnected, but I can't say for sure.ġ) Is there a better approach for attempting to handle errors like this with FileSystemWatcherĢ) Is there a property that allows me to determine that the FSW has become disconnected from the file? I notice there is a non-public member of the FSW "stopListening", which appears to be set to true when the FSW becomes disconnected.
