v1.2.0

Frequenz channels Release Notes

Upgrading

• FileWatcher: The file polling mechanism is now forced by default. This provides reliable and consistent file monitoring on network file systems (e.g., CIFS). However, it may have a performance impact on local file systems or when monitoring a large number of files.
  • To disable file polling, set the force_polling parameter to False.
  • The polling_interval parameter defines the interval for polling changes. This is relevant only when polling is enabled and defaults to 1 second.

New Features

• Timer.reset() now supports setting the interval and will restart the timer with the new interval.

Bug Fixes

• FileWatcher:

  • Fixed ready() method to return False when an error occurs. Before this fix, select() (and other code using ready()) never detected the FileWatcher was stopped and the select() loop was continuously waking up to inform the receiver was ready.
  • Reports file events correctly on network file systems like CIFS.

• Timer.stop() and Timer.reset() now immediately stop the timer if it is running. Before this fix, the timer would continue to run until the next interval.

What's Changed

• Timer: Add support for rearming timer with new interval by @Marenz in #321
• Enable polling in file watcher by @daniel-zullo-frequenz in #322
