Bumps actionview from 8.1.3.1 to 8.1.4.1.

Release notes

Sourced from actionview's releases.

8.1.4.1

Active Support

• ActiveSupport::MessagePack no longer deserializes an unsafe ActiveSupport::SafeBuffer as html_safe.

  A SafeBuffer that was no longer html_safe?, for example after an in-place gsub!, was deserialized as an html_safe SafeBuffer. It is now serialized with an unsafe marker and deserialized as a String. Earlier versions of Rails cannot read an unsafe buffer serialized this way.

• ActiveSupport::Inflector#safe_constantize matches the constant name in a LoadError message as a literal string instead of building a Regexp from it.

  The name's segments were interpolated unescaped into the pattern, so input that reaches safe_constantize, such as the channel identifier in an Action Cable subscribe command, chose the source passed to the regexp compiler.

Active Model

• No changes.

Active Record

• No changes.

Action View

• Skip attribute names in tag helpers that are blank once converted to a string.

  A Symbol such as :" " is not blank, because Symbol#blank? is Symbol#empty?, so it reached the escaping step and produced an attribute with no name. The asset helpers symbolize their keys, so an ordinary String key reached the same place.

• Fix strip_tags to encode " and ' in its output.

  strip_tags returns an html_safe string, but was not encoding quotation marks. The method now encodes all five HTML-significant characters (&, <, >, ", '), consistent with the existing html_safe convention.

  Output used outside HTML, such as in a text template or JSON, now contains " and &[#39](https://github.com/rails/rails/issues/39); where it contained " and '. CGI.unescapeHTML decodes them.

• Escape the matched phrase before substituting it into highlight's :highlighter.

  A match was copied into each \1 of the highlighter as it appeared in the sanitized text, which keeps " and ' as they are, so a match containing a quote ended a quoted attribute value such as the documented '<a href="search?q=\1">\1</a>' and added attributes of its own. Each substituted group now goes through ERB::Util.html_escape_once, so quotes in a match render as " and &[#39](https://github.com/rails/rails/issues/39);. Only the numbered placeholders \0 to \9 are expanded, and a match never replaces the > that closes a tag.

• Require rails-html-sanitizer 1.7.2 or later.

  With the HTML5 sanitizer, Nokogiri before 1.19.5 left < and > unescaped in attribute values. highlight and simple_format, which edit the sanitized HTML as a string, could then turn markup inside an attribute value into live elements. rails-html-sanitizer 1.7.2 requires
