[WIP] Import latest gem versions from rubygems.org

[onk]

What

Automaticaly update the latest version of gems. It is useful to know it is up to date.

current: The newest version used in the registered project in gem_collector.

Now it wants this: The latest version on rubygems.org.

How

1. Download https://rubygems.org/specs.4.8.gz.
2. Import it to gem_collector_latest_gem_versions table.
3. Automaticaly update it by sidekiq plug-in, whenever, vanilla cron, etc.

Like this:

rails runner "GemCollector::UpdateLatestGemVersionsJob.new.perform"

Implements

Table name: latest_gem_versions

Name	Type	Attributes
id	integer	not null, primary key
gem_name	string	not null
version	string

• index_latest_gem_versions_on_gem_name (unique):
  • gem_name

gem_name column has unique constraint and import with :on_duplicate_key_update option.

Wish to consult

• It does not fetch prerelease_specs. Is it OK? I think when calcurating latest gem rate, beta version should be excluded.
• gem's platform is fixed to "ruby". Is it OK?

It looks a good starting point to me, but I have one question; why do you import only latest versions? With only latest versions, we can judge "up-to-date or not", but cannot measure "how up-to-date".

Thank you for review!

why do you import only latest versions?

I only thought about checking "up-to-date or not", like this. https://gyazo.com/dc491bc97a5b8b59b979f054f015ed1c It seems better to keep all gem versions, but how do I show it 🤔
