how our upload scheduler got smarter

You might have noticed our upload system feels a little different lately. We've tweaked how Autoretto schedules your music releases. It’s a subtle change, but it makes the whole process more robust and less prone to missed slots or accidental duplicates. Think of it less like a strict calendar and more like a system that always knows what needs doing next based on what's already done.

Previously, our scheduler might have looked ahead to the next available future timestamp. If something went wrong, or the system restarted, it could lose track of what was supposed to go out when. This new approach flips that. Now, the scheduler looks at the most recent *past* upload slot that's still empty. It checks if there's an available time slot that's already occurred but hasn't had a video published to it yet.

This 'catch-up' window is key. It means if Autoretto is offline for a bit, or if a particular release had an issue and didn't publish, it doesn't just get skipped. When the system comes back online or resolves the issue, it can go back and fill those missed slots. It's designed to make sure your music gets published on schedule, even if the technology has a hiccup.

How does this actually happen without you needing to do anything? We use a simple, recurring task, often called a cron job. This hourly cron job wakes up and checks for any of these 'missed' or 'catch-up' slots. If it finds one, and there's a finished, ready-to-go video for it, it triggers the upload. It's like a diligent assistant making sure no tasks fall through the cracks. This happens automatically, in the background, with no browser needing to be open.

The goal here is efficiency and reliability. We don't want you to have to manually check if an upload failed or if a slot was missed. The system is built to be self-correcting for these common scheduling issues. It prioritizes getting your music out there in the order it was intended.

One of the biggest challenges with automated publishing is preventing duplicate uploads. If a scheduler runs, then gets interrupted, and then tries to run again, it could theoretically try to upload the same video twice. To stop this, we introduced a 'last release stamp.' Every time a video is successfully published, we record the exact timestamp of that release.

Before any new upload is sent, the system checks this last release stamp. It essentially asks, 'Has a video already been published at or after the intended time for this release?' If the answer is yes, even if the system was interrupted and is now trying to process that same slot again, it simply skips the upload. This simple check, combined with the catch-up window and the hourly cron, ensures that you get one polished release per slot, every time, without accidental duplication.

This refined scheduling logic makes Autoretto more dependable. It means you can set your music to be released and trust that the system is actively working to fulfill those commitments, even if minor interruptions occur. It's about making automation feel less like a black box and more like a reliable tool working for you.
