Running with patch

$ QUEUE_ADAPTER=async ./fix-preview-image-race-condition.rb 

Yields

Creating a post and uploading a video

searls

TIL this script helped me figure out that

1. Given a previewable attachment (video, pdf) has 2 preprocessed variants
2. After being attached, these are enqueued [ActiveStorage::AnalyzeJob, ActiveStorage::TransformJob, ActiveStorage::TransformJob]
3. All 3 jobs will (I assume?) separately download the video from storage to a tmp file
4. Running asynchronously, a race condition results: both transform jobs will see no blob.preview_image exists yet and will BOTH create one
5. Since a blob only has one preview_image attached, one preview image (and any variants associated with it) will be orphaned
6. As a result when the attachment is purged, those orphaned blobs and variant record will fail to be purged

Not awesome things that happen in this case:

Welcome to Matsumoto. I mean, physically or virtually. We're so happy to have you here. I think I'm seeing a thousand people in front of me here in this venue. I think it's been a while. It's been a while. It's been like four years since we had this number of people in the Kaigi venue. Four years. I'd like to say thank you for gathering again, coming back to RubyKaigi. I feel like the Kaigi is back. Because of you. Because of you, in the venue. Because you are back. But actually, since there have been four years of blank period of Kaigi, I said you're back, but actually we should be having newcomers to the Kaigi. So, please let me know. Please tell me, who are the first-timers of RubyKaigi? I mean, raise your hand if you are coming to RubyKaigi for the first time. Thank you. Thank you for coming. We really welcome your attendance. So, one thing I'd like to tell you, I have to tell you is... Um... Not that. The COC thing, the Code of Conduct, the core of the conduct is be nice to each other. So, let us be nice
