Why bundler starts to download all specs for the gem

[hurricup]

I have a system ruby on ubuntu 22.04 with default bundler 2.22

Bundler version 2.2.22

I have a simple Gemfile :

source 'http://rubygems.org'

gem 'cucumber'

And i need to bundle install it. This is a scenario from one of tests. And it worked fine until today morning.

But now it looks like for some reason bundler starts to download all cucumber specs, and dies on cucumber/cucumber-ruby#136

Question is why and is it possible to avoid such issues.

I was unable to reproduce this on my local machine or in the same docker container test scenario runs. Probably there are some infrastructural issues on the test host machine.

For some reason the compact index API requests timed out. In that case, Bundler falls back to fetching the full index. It was most likely a temporary problem.

I see. But note, that this may cause a problem when some old version of a gem was broken (broken gemspec), bundler unable to skip it and fails. When it may be shouldn't.
