Right.. I spent the hours leading up to the year change by adding a YouTube to MP3 downloader into my Telegram bot. After a bit of fiddling it turned out okay, and the commit for it was mentioned to the last for the year 2020.

I mentioned this in one of my chats, and users came in with more issues. Told them it's the last commit for the year and I'll keep myself to it. I did adjust the code a bit though to fix those issues, awaiting a commit after midnight.

Midnight passes and 2020 turns into 2021.

I commit the new features, and quickly implemented another one I already thought of as well, but needed its own commit.

Quickly afterwards it turns out that the /mp3 feature actually breaks the bot somewhat, especially on long tracks. Users add a slew of 10h songs into what essentially became a long queue of single-threaded bot action (or rather lack thereof).

I made the /mp3 command accessible to myself only like I did with some other administrative commands already. Still no dice, the bot rejected the commands but executed part of the /mp3 command anyway.

I look a bit further into the code and it turns out that while I was restructuring some functions, I forgot to make the admin() function exit the script after it sends the rejection onwards. This was a serious security issue and meant that all authentication was void. Fortunately the chat did not realize this - one of the commands that became available as a result was literally a terminal on the bot's system.

I fix the issue in 7 commits after midnight total, 3 of which were related to /mp3 and admin(). We're now 1 hour after midnight.

Happy New Year everyone... :')
