Hey, I've been switching a lot of feeds over to the new infra over the past few hours, if you still notice any issues in one of your (or someone elses) skyfeed feeds right NOW, in this moment, please reply here with a link to it. I'll take a look and fix them if needed!

I continue to see intermittent failure to load for the gift link feed

Today's status: feed content is way old.

@redsolver.dev the gift link feed has not updated in a day at this point. Other feeds don't seem to have the same issue. Any idea what's different?

It's mostly about RegEx complexity, the new engine has stricter timeouts and I still have some work to do in caching efficiency of already processed feeds, which results in some feeds with larger regex queries to fail to compute in time. Actively working on ironing these bugs out atm.

Any idea why after working reliably for almost 24h, the gift link feed got stuck again?

I tried splitting the big regex in half with a stash/pop but that didn't help. Waiting on your fix

Worked for a few hours this morning, but gift links feed is stuck again. How is the limit on big regular expressions structured? A leaky bucket on total run time? Something simpler like a per-step cap?

I tried changing how I use some of the lists I have and splitting the regex even more to keep all operations under 100ms. That seems to have gotten things going again. Would really help to make the list operations faster though; they're important for enabling moderation.
