Re: [photospace-developer] FileSysemWatcher

[alon s. <as...@gm...>]

Klaus, that sounds fine. If you make any improvements, please share
them back with the photospace project.

FileSystemWatcher could definitely be better. A few things I have
considered as improvements:

1. OS-specific hooks
Most operating systems have native filesystem event mechanisms that
forgo the need to poll the file system for changes. With JNI hooks to
these mechanisms, FileSystemWatcher would use far fewer system
resources to do its job.

There are commercial libraries that do this:
http://www.servertec.com/products/sfc/features.html.

2. Sleep/Wake up
For photospace, there are often long periods of time where there are
no changes to the filesystem and then short periods where there are
lots of changes. It could be useful for FileSystemWatcher to check for
changes frequently when there have been recent changes and to check
for changes infrequently when there have not been changes for a while.
