New date format in gemspec breaks older rubygems version

dubstep · September 20, 2011, 7:03pm

I forget why but I’m stuck using rubygems 1.7.2, which means I
occasionally get the dreaded “invalid date format in specification”
error message

What sets the date format?

For example. with rubygems-bundler

Invalid gemspec in [/usr/local/rvm/rubies/ree-1.8.7-2011.03/lib/ruby/
gems/1.8/specifications/rubygems-bundler-0.2.6.gemspec]: invalid date
format in specification: “2011-09-16 00:00:00.000000000Z”

If you look on github the date is 2011-09-16. no time information is
added

github.com

rvm/rubygems-bundler/blob/master/rubygems-bundler.gemspec

#!/usr/bin/env ruby
# -*- encoding: utf-8 -*-

Kernel.load File.expand_path("../lib/rubygems-bundler/version.rb", __FILE__)

Gem::Specification.new do |s|
  s.name        = "rubygems-bundler"
  s.version     = RubygemsBundler::VERSION
  s.authors     = ["Josh Hull", "Michal Papis"]
  s.email       = ["[email protected]", "[email protected]"]
  s.homepage    = "https://rvm.github.com/rubygems-bundler"
  s.summary     = %q{Stop using bundle exec}
  s.description = %q{Stop using bundle exec. Integrate Rubygems and Bundler. Make rubygems generate bundler aware executable wrappers.}
  s.license     = 'Apache-2.0'

  s.files       = `git ls-files`.split("\n")
  s.test_files  = `git ls-files -- {test,spec,features}/*`.split("\n")

  s.add_dependency "bundler-unload", ">=1.0.2"
  s.add_dependency "executable-hooks", ">=1.5.0"

So what adds the 00:00:00.000000000Z? Is it part of the rubygems
push process?

This gem supports older versions of rubygems but once it is uploaded
to rubygems.org it will only work on 1.8.x :-\

Thanks for any pointers.

FYI… The Gem author fixed this issue by rebuilding the Gem with
1.8.7. He mentioned something about the YAML version. I guess I
should learn about the Gem deploy process to better understand what
the root cause of the issue was.
