[DRE-maint] Bug#998638: ruby-localhost: spec/localhost/protocol_spec.rb fails on ci.debian.net and salsa

[Antonio Terceiro]

Source: ruby-localhost
Version: 1.1.8-2
Severity: serious
Tags: bookworm sid ftbfs
User: debian-ruby at lists.debian.org
Usertags: ruby3.0

I was looking at the testing migration excuses for puma, which brought
me to ruby-localhost. spec/localhost/protocol_spec.rb very often, but
not always, fails. This is currently blocking testing migration.

Example of failed logs:

on ci.debian.net:
https://ci.debian.net/data/autopkgtest/testing/amd64/r/ruby-localhost/16388045/log.gz

on salsa:
https://salsa.debian.org/ruby-team/ruby-localhost/-/jobs/2150375 (i386 build)
https://salsa.debian.org/ruby-team/ruby-localhost/-/jobs/2150382 (autopkgtest)

I even tried a new upstream version 1.1.9 that is available to see if it
made things better, but it doesn't:
https://salsa.debian.org/ruby-team/ruby-localhost/-/commits/test
https://salsa.debian.org/ruby-team/ruby-localhost/-/pipelines/310716

One option is skipping this test, at least for now, with a patch like
this:

----------------8<----------------8<----------------8<-----------------
diff --git a/debian/ruby-tests.rake b/debian/ruby-tests.rake
index cf1591e..6010dd7 100644
--- a/debian/ruby-tests.rake
+++ b/debian/ruby-tests.rake
@@ -2,4 +2,5 @@ require 'gem2deb/rake/spectask'

 Gem2Deb::Rake::RSpecTask.new do |spec|
   spec.pattern = './spec/**/*_spec.rb'
+  spec.exclude_pattern = './spec/localhost/protocol_spec.rb'
 end
----------------8<----------------8<----------------8<-----------------

But ideally we would want to fix it.
