Issue #20686 has been reported by ronricardo (Roniece Ricardo). ---------------------------------------- Bug #20686: URI::HTTPS can build URI with blank, invalid host https://bugs.ruby-lang.org/issues/20686 * Author: ronricardo (Roniece Ricardo) * Status: Open * ruby -v: 3.4.0+ * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- In Ruby 3.4.0+, calling `URI::HTTPS.build(host: "")` does not raise `URI::InvalidComponentError` as expected. Instead, it returns `#<URI::HTTPS https://>` I think this was introduced in [this PR](https://github.com/ruby/uri/pull/90). ## Steps to Reproduce ### 1. Environment: - **Ruby Version:** 3.4.0+ ### 2. Steps: - Open an IRB session. - Run: ```ruby URI::HTTPS.build(host: "") ``` ### 3. Expected Behavior: - `URI::InvalidComponentError` should be raised due to the invalid empty `host` component. ### 4. Actual Behavior: - Returns `#<URI::HTTPS https://>` without raising an error. ### Ruby 3.1.4: ```ruby irb(main):008:0> RUBY_VERSION => "3.1.4" irb(main):009:0> URI::HTTPS.build(host:"") /home/vscode/.rbenv/versions/3.1.4/lib/ruby/3.1.0/uri/generic.rb:601:in `check_host': bad component(expected host component): (URI::InvalidComponentError) ``` ### Ruby 3.4.0: ```ruby irb(…):015> RUBY_VERSION => "3.4.0" irb(...):016> URI::HTTPS.build(host:"") => #<URI::HTTPS https://> ``` -- https://bugs.ruby-lang.org/
