From d79366b4c9619e70a2c292b3a7c0311618eba9be Mon Sep 17 00:00:00 2001 From: Marco Costa Date: Tue, 8 Jan 2019 17:52:06 -0500 Subject: Preserve Bundle configuration during app generation (#34755) When generating a new rails application (rails new) using a custom template that includes gems from an authenticated source, the user has to provide credentials to bundler. One way to do this is by exporting environment variables, for example: export BUNDLE_GITHUB__COM=user:pass: provides credentials for bundler to fetch gems from github.com. The problem this PR addresses is that we are currently scrubs all /BUNDLE_.*/ environment variables by wrapping our system calls in Bundler.with_clean_env. We do this because we don't want our commands executed against the generated project to use the generator's bundler environment (e.g. our gems): the generated project should use it's own configuration. The problem with Bundler.with_clean_env is that, on top of restoring environment variables to their original state, it also scrubs any /BUNDLE_.*/ variables, which is harmful for authenticated gem sources. This PR replaces Bundler.with_clean_env with Bundler.with_original_env, which only restores environment variables to their initial state, without additional scrubbing. --- railties/lib/rails/generators/app_base.rb | 20 +++++++++++--------- 1 file changed, 11 insertions(+), 9 deletions(-) (limited to 'railties/lib/rails') diff --git a/railties/lib/rails/generators/app_base.rb b/railties/lib/rails/generators/app_base.rb index 3778690ef6..8df2b32dd2 100644 --- a/railties/lib/rails/generators/app_base.rb +++ b/railties/lib/rails/generators/app_base.rb @@ -388,19 +388,21 @@ module Rails # its own vendored Thor, which could be a different version.
