Use PollingObserver, that is, instead of letting watchdog decide anĪppropriate observer like in the example above, do: from import PollingObserver as Observer Dependencies When you want to watch changes in CIFS, you need to explicitly tell watchdog to You may need to configure Vim appropriately to disable If you use Vim to edit your files, the on-modified eventsįor those files will not be triggered by watchdog. It creates backup files and then swaps them in to replace Vim does not modify files unless directed to do so. About using watchdog with editors like Vim Not a very scalable way to monitor a deeply nestedĭirectory of files and directories with a large number ofįiles. To monitor file descriptors just makes this a painful way
That plus the enormousĪmount of bookkeeping that watchdog needs to do in order This is an inherent problem with kqueue because it usesįile descriptors to monitor files. To do that is to edit your ~/.profile file and add Number of files that you will be monitoring.
Running on your system to be increased to more than the Number of file descriptors allowed to be opened by programs Note that when using watchdog with kqueue, you need the OS-independent (polling the disk for directory snapshots and comparing them

On Windows, please install PyYAML using the binaries they provide.
Here’s how youĭo it on Ubuntu: $ sudo apt install libyaml-dev On Linux, use your favorite package manager to install LibYAML. To install LibYAML: $ brew install libyaml Which brings a performance boost to the PyYAML parser. The watchmedo script depends on PyYAML which links with LibYAML, $ python -m pip install -e "." Installation Caveats Install from source: $ python -m pip install -e. Install from PyPI using pip: $ python -m pip install -U watchdog
