Re: monitoring file changes (win32)

It seems there is no way on Windows to notify you that a file (handle) has been closed, as there might be multiple handles open to the same file. I guess the closest you'll get is Re: how to permanently monitor a directory, which will notify you of "no changes" after a certain amount of time has passed, in addition to other changes.

Hello and thank you for the hint. The solution so far seems to be to thread the application, run $watcher->get_results() every 10 seconds, stat() each file and if the modification date is less than localtime()-10 ignore it. It should be picked by the next run. On to reading how threads work in Win32..	[reply]

After some more experimenting, I believe an apology is needed for the second point: all my tests were done in virtual machines - Virtualbox and Parallels. I have now tried the same using Microsoft's .Net System.IO.FilesystemWatcher and noticed the same problems. Something in the way those emulators handle filesystem changes causes events to not be triggered. My conclusion so far is that it's not a FS::W issue. POE::C::DW:O does work in the same setups though, this might be because it doesn't use Win32::ChangeNotify Any hints on where I should move this topic would be greatly appreciated.	[reply]
