0.3.1

Bug Fix Log

Notifications still showed up even after they were deleted:

• daemon.py now keeps checking the database in a loop
• It only schedules tasks that are currently in the database
• If a task is deleted, it won’t be scheduled again
• This way, deleted reminders don’t show up anymore
• A set is used to avoid scheduling the same task more than once

0.3.0

Update Log

Highlights:

• Converted simple one-time reminder runner into a fully persistent, self-updating background reminder daemon with systemd user service integration.

Changes Made:

• Initial issue

  • Reminders worked but only if scheduled at program start.
  • New tasks added after startup were ignored unless the service was restarted.

• Root cause

  • Tasks were loaded only once at startup.
  • schedule.run_pending could only trigger jobs that were scheduled beforehand.

• Temporary fix tested

  • Added tasks manually for 1–2 minutes in the future.
  • Restarted the service to pick up new tasks.
  • Reminders worked after restart, but the process was manual and not scalable.

• Permanent fix implemented

  • Modified daemon.py to:
    • Continuously poll the database every second inside the main loop.
    • Track already scheduled tasks using a set.
    • Schedule only new tasks that were not already scheduled.
  • Now new reminders appear without needing to restart the service.

• Notification not showing up issue

  • Root cause: notify2 needs a DBUS graphical session environment.
  • Solved by:
    • Moving from system-wide service to user-specific systemd service.
    • Setting environment variables inside the .service file:
      • DISPLAY=:0
      • DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/%U/bus

• Service location fixed

  • Moved the .service file to ~/.config/systemd/user/.
  • Updated the Makefile to:
    • Use systemctl --user commands.
    • Remove all sudo dependency.
  • Service now runs correctly under the user session and can send desktop notifications.

• Final test and confirmation

  • Added a task using make add.
  • Without restarting, the new reminder triggered at the correct time.
  • Confirmed that there were no duplicate tasks and no missed triggers.
  • Background daemon now runs continuously and reliably.

Final Features After Upgrade:

• Automatically loads new reminders without requiring a service restart.
• Lightweight background process using schedule.run_pending loop.
• Fully integrated with systemd user services (no root needed).
• Desktop notifications work correctly in the graphical session.
• Database-driven, scalable, and robust reminder scheduling.
