Yeah, srsly dude. This isn’t right for us either. I think that brew upgrade I did last night broke something, must have upgraded node. Apparently upgrading beyond node-sass 6.0.1 is fine now. Last time this happened I had to downgrade node.

No, can’t see anything above 6.0.1 out there :S I need to get back to node@14 again.

USB debugging on a Redmi.

This doesn’t appear anywhere in our codebase. Does iPhone Safari inject this under some circumstances?

undefined is not an object (evaluating 'document.getElementsByTagName('video')[0].webkitExitFullScreen')

I do know how to write, but today the only thing I can make out is Nagios and rubocop -A

Somewhere in there there is something about JSONAPI-Resources attributes, maybe.

Looks like Rails 6.0.4 upgrade has mangled the SQL JSONAPI-Resources is constructing.

You wake in a dark room and someone has only gone and tainted your master branch by merging in multiple commits spanning weeks of work. We can’t possibly unpick 100+ commits, what the hell even were they? But we need master back as it was.

We can however, reset our master to a particular commit in the past that we trust.

git checkout master
git reset --hard <somehash>
git push --force origin <somehash>:master

Total 0 (delta 0), reused 0 (delta 0), pack-reused 0
To github.com:somerepo/someproject.git
 + <someotherhash>...<somehash> <somehash> -> master (forced update)

There were tears of joy and shaky hands, but it was fine.

Building RMagick with native extensions is playing up again… I use homebrew so I was looking for the right solution.

Upgrading to Mongoid 7.x and found a pretty frightening change in behaviour for OR queries. Any unclear OR declarations could have devastating side-effects.

5.4.1

irb(main):001:0> Train.where(id: 1).or(:expiry.gte => Date.today)
=> #<Mongoid::Criteria
  selector: {"_id"=>1, "$or"=>[{"expiry"=>{"$gte"=>2021-07-07 00:00:00 UTC}}]}
  options:  {:sort=>{"number"=>1}}
  class:    Train
  embedded: false>

irb(main):002:0> Train.or(:expiry.gte => Date.today).where(id: 1)
=> #<Mongoid::Criteria
  selector: {"$or"=>[{"expiry"=>{"$gte"=>2021-07-07 00:00:00 UTC}}], "_id"=>1}
  options:  {:sort=>{"number"=>1}}
  class:    Tenant
  embedded: false>

Previously, or queries would append the selector so where(id: 1) and some OR statement

7.3.0

irb(main):006:0> Train.where(id: 1).or(:expiry.gte => Date.today)
=> #<Mongoid::Criteria
  selector: {"$or"=>[{"_id"=>1}, {"expiry"=>{"$gte"=>2021-07-07 00:00:00 UTC}}]}
  options:  {:sort=>{"number"=>1}}
  class:    Train
  embedded: false>

irb(main):007:0> Train.or(:expiry.gte => Date.today).where(id: 1)
=> #<Mongoid::Criteria
  selector: {"$or"=>[{"expiry"=>{"$gte"=>2021-07-07 00:00:00 UTC}}], "_id"=>1}
  options:  {:sort=>{"number"=>1}}
  class:    Train
  embedded: false>

Now it combines them depending on the order they are declared. I am not entirely sure I like either way of declaring this. Having come from ActiveRecord land I would nearly always assume that you’re AND-ing everything you chain onto a scope.

So in this case we could look for our Tenant by ID, but actually find the first unexpired one instead. That’s one hell of a security hole.

I think the lesson here is to be extra cautious when using ‘OR’ in either ActiveRecord or Mongoid since the outcome is not always as obvious as you might think.

An upgrade or two back our Rails 6 app lost line comments. I can’t remember if it was trying to improve speed or the upgrade to sassc. Well it’s fixed now.

# Debug mode disables concatenation and preprocessing of assets.
  # This option may cause significant delays in view rendering with a large
  # number of complex assets.
  # config.assets.debug = true
  # config.sass.line_comments = false
  config.sass.inline_source_maps = true
