# Leverages the BroadcastLogger introduced in Rails 7.1 to wrap the current
# logger in a new logger that broadcasts to both the current logger and $stdout
#
# (Announcement: https://rubyonrails.org/2023/9/29/this-week-in-rails)
#
# If the current logger already broadcasts to $stdout, it will not be wrapped,
# making it safe to call this method multiple times without knowing the current
# logging "sitch".
#
# Usage probably looks something like this:

/* preventScrollWhenSoftKeyboardAppearsIfThereIsPlentyOfRoom(event)
 *
 * Attach this handler to `touchstart` on any UI control that brings up the keyboard when you don't want iOS
 * MobileSafari to scroll when a user taps it. Assumes that the input is near the top of the page and the user has
 * not scrolled down (specific to my case, sorry!)
 *
 * requires top-level CSS directives so we can add it to the body:
 * ```
 * .prevent-ios-focus-scrolling {
 *   position: fixed;

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:

searls

class FeedsController < ApplicationController
  def index
    @posts = Post.with_visuals.order(published_at: :desc)
  end
end

Sometimes a Controller is Just a Controller

Abstract

You grok SOLID. You practice TDD. You've read Sandi's book…twice. You rewatch Destroy All Software monthly. You can pronounce GOOS. You know your stuff!

But some of your coworkers say your code is too complex or confusing for them. You might rush to conclude that must be a them problem.

But doubt lingers: what if they're right?
