Joyce's Friday

I removed the line spaces from the version_message method and in the source/git.rb file. Moved the rspec tests for gems, git, and source to the correct file in the spec/update directory and the proper place in the file.

Add rspec test for when you run bundle outdated with the wrong gem name it returns non-zero exit code.

Started working on adding a -all flag to bundle update. Instead of updating the gems when users run bundle update, move that functionality to bundle update –all. Then, bundle update should print instructions/messages on how to update because “many people think that they should run bundle update after git pull, but that mostly just messes everything up.”

Started working on bundler-features issues #17

Warn if using a version of bundler older than that specified in the lockfile

From Issue #2239 in bundler/bundler

gucki: bundler does not enforce version of itself specified in Gemfile.lock No milestone No one is assigned My Gemfile.lock has bundler locked at 1.2.3. Now on a different where bundler 1.0.21 is installed, I can run bundle exec cap deploy. However the deploy fails, because the capistrano version is incompatible with that bundler version.

The main problem is that bundler does not enforce the locked version of 1.2.3 for itself. It silently uses 1.0.21.

Andre: If you want the version enforced, put it in your Gemfile. The locked version is for reference, so you know which version of Bundler created the lockfile.

gucki: If there any special reason why it's different to the normal behavior of all other gems? At least a warning should be emitted?

Andre: Yes, it's different because otherwise you would never be able to upgrade Bundler.

I know that we had agreed to print a warning if you try to use an older version, but I'm not sure if that code was ever written. It's definitely a good idea.

./lib/bundler/cli.rb: def exec(*args)

lib/bundler/cli.rb line 526 def exec(*args) Bundler.definition.validate_bundler! Bundler.definition.validate_ruby! Bundler.load.setup_environment

add a validate bundler method ./lib/bundler/definition.rb:

find version of bundler in Gemfile.lock

If you run bundle exec it should the version of bundler in the lockfile or print a warning. bundler is already loaded and it's too late but it should check the lock for a bundler version constraint and abort if it doesn't meet it

bundle exec should check for a bundler version constraint, and print a warning if it doesn't meet it

bundle show bundler

gem list bundler

specify a version in the Gemfile.lock that is not the version on my computer . Get it to give an error.

What does it do now?
