When will the wait for Syd to finish writing folon finally end? Get the latest news and updates.

Alright, so here’s the deal. I was wrestling with this beast of a task: “wait for syd to finish writing folon.” Sounds simple, right? Wrong! This turned into a whole saga, lemme tell ya.

First, I started by figuring out what “folon” even is. Turns out, it’s some kinda configuration file that Syd was crafting. Crucial for deploying the new service, apparently. So, my job was basically to sit tight until that file was ready, then kick off the deployment.

Initially, I thought, “Easy peasy, I’ll just ping Syd every few minutes.” So I wrote a quick-and-dirty bash script:

• Loop every 5 minutes
• ssh into Syd’s machine
• Check if folon exists and isn’t empty

Yeah, that worked…kinda. But it was super clunky. Constant SSH connections, plus it relied on Syd’s machine being up and reachable. Not ideal.

Then, I thought, “Okay, let’s get a bit smarter.” We’re using a shared Git repo for all config files, so I switched gears. Instead of checking Syd’s machine, I’d watch the Git repo.

My second attempt looked like this:

• Use git ls-remote to check for the existence of folon on Syd’s branch.
• If it’s there, great! Download it.
• If not, sleep for a bit and try again.

This was better! Fewer moving parts, and less reliant on Syd’s individual setup. But…still kinda meh. It was polling, which is never great. Plus, it didn’t account for Syd starting the file, but not finishing it. I needed to make sure the file was actually complete before grabbing it.

So, round three! I talked to Syd (shocking, I know!) and we agreed on a signal. When Syd was done writing folon, they’d commit it with a specific commit message: “feat: folon complete.”

Now that was something I could work with! I refactored my script to use the Git log:

1. git log --oneline to scan the recent commits on Syd’s branch.
2. Look for the “feat: folon complete” commit message.
3. Once that commit is found, then download the folon file and proceed with the deployment.

Bingo! This worked like a charm. No more polling, no more SSH headaches, just a simple, reliable way to wait for Syd to finish writing folon. The whole process became much cleaner.

The key takeaways for me were:

• Don’t be afraid to iterate and refine your approach.
• Communication is key! Talking to Syd saved me a ton of time.
• Look for signals, not just states. Waiting for a specific event is often more efficient than constantly checking for a condition.

So, yeah, that’s how I wrestled with waiting for Syd to finish writing folon. It was a bit of a journey, but I learned a few things along the way. Hopefully, this helps someone else out there!
