1.13.0 / 2022-01-06

Notes

Ruby

This release introduces native gem support for Ruby 3.1. Please note that Windows users should use the x64-mingw-ucrt platform gem for Ruby 3.1, and x64-mingw32 for Ruby 2.6–3.0 (see RubyInstaller 3.1.0 release notes).

This release ends support for:

• Ruby 2.5, for which official support ended 2021-03-31.
• JRuby 9.2, which is a Ruby 2.5-compatible release.

Faster, more reliable installation: Native Gem for ARM64 Linux

This version of Nokogiri ships experimental native gem support for the aarch64-linux platform, which should support AWS Graviton and other ARM Linux platforms. We don't yet have CI running for this platform, and so we're interested in hearing back from y'all whether this is working, and what problems you're seeing. Please send us feedback here: Feedback: Have you used the aarch64-linux native gem?

Publishing

This version of Nokogiri opts-in to the "MFA required to publish" setting on Rubygems.org. This and all future Nokogiri gem files must be published to Rubygems by an account with multi-factor authentication enabled. This should provide some additional protection against supply-chain attacks.

A related discussion about Trust exists at #2357 in which I invite you to participate if you have feelings or opinions on this topic.

Dependencies

• [CRuby] Vendored libiconv is updated from 1.15 to 1.16. (Note that libiconv is only redistributed in the native windows and native darwin gems, see LICENSE-DEPENDENCIES.md for more information.) [#2206]
• [CRuby] Upgrade mini_portile2 dependency from ~> 2.6.1 to ~> 2.7.0. ("ruby" platform gem only.)

Improved

• {XML,HTML4}::DocumentFragment constructors all now take an optional parse options parameter or block (similar to Document constructors). [#1692] (Thanks, @JackMc!)
• Nokogiri::CSS.xpath_for allows an XPathVisitor to be injected, for finer-grained control over how CSS queries are translated into XPath.
• [CRuby] XML::Reader#encoding will return the encoding detected by the parser when it's not passed to the constructor. [#980]
• [CRuby] Handle abruptly-closed HTML comments as recommended by WHATWG. (Thanks to tehryanx for reporting!)
• [CRuby] Node#line is no longer capped at 65535. libxml v2.9.0 and later support a new parse option, exposed as Nokogiri::XML::ParseOptions::PARSE_BIG_LINES, which is turned on by default in ParseOptions::DEFAULT_{XML,XSLT,HTML,SCHEMA} (Note that JRuby already supported large line numbers.) [#1764, #1493, #1617, #1505, #1003, #533]
• [CRuby] If a cycle is introduced when reparenting a node (i.e., the node becomes its own ancestor), a RuntimeError is raised. libxml2 does no checking for this, which means cycles would otherwise result in infinite loops on subsequent operations. (Note that JRuby already did this.) [#1912]
• [CRuby] Source builds will download zlib and libiconv via HTTPS. ("ruby" platform gem only.) [#2391] (Thanks, @jmartin-r7!)
• [JRuby] Node#line behavior has been modified to return the line number of the node in the final DOM structure. This behavior is different from CRuby, which returns the node's position in the input string. Ideally the two implementations would be the same, but at least is now officially documented and tested. The real-world impact of this change is that the value returned in JRuby is greater by 1 to account for the XML prolog in the output. [#2380] (Thanks, @dabdine!)

Fixed

• CSS queries on HTML5 documents now correctly match foreign elements (SVG, MathML) when namespaces are not specified in the query. [#2376]
• XML::Builder blocks restore context properly when exceptions are raised. [#2372] (Thanks, @ric2b and @rinthedev!)
• The Nokogiri::CSS::Parser cache now uses the XPathVisitor configuration as part of the cache key, preventing incorrect cache results from being returned when multiple XPathVisitor options are being used.
• Error recovery from in-context parsing (e.g., Node#parse) now always uses the correct DocumentFragment class. Previously Nokogiri::HTML4::DocumentFragment was always used, even for XML documents. [#1158]
• DocumentFragment#> now works properly, matching a CSS selector against only the fragment roots. [#1857]
• XML::DocumentFragment#errors now correctly contains any parsing errors encountered. Previously this was always empty. (Note that HTML::DocumentFragment#errors already did this.)
• [CRuby] Fix memory leak in Document#canonicalize when inclusive namespaces are passed in. [#2345]
• [CRuby] Fix memory leak in Document#canonicalize when an argument type error is raised. [#2345]
• [CRuby] Fix memory leak in EncodingHandler where iconv handlers were not being cleaned up. [#2345]
• [CRuby] Fix memory leak in XPath custom handlers where string arguments were not being cleaned up. [#2345]
• [CRuby] Fix memory leak in Reader#base_uri where the string returned by libxml2 was not freed. [#2347]
• [JRuby] Deleting a Namespace from a NodeSet no longer modifies the href to be the default namespace URL.
• [JRuby] Fix XHTML formatting of closing tags for non-container elements. [#2355]

Deprecated

• Passing a Nokogiri::XML::Node as the second parameter to Node.new is deprecated and will generate a warning. This parameter should be a kind of Nokogiri::XML::Document. This will become an error in a future version of Nokogiri. [#975]
• Nokogiri::CSS::Parser, Nokogiri::CSS::Tokenizer, and Nokogiri::CSS::Node are now internal-only APIs that are no longer documented, and should not be considered stable. With the introduction of XPathVisitor injection into Nokogiri::CSS.xpath_for there should be no reason to rely on these internal APIs.
• CSS-to-XPath utility classes Nokogiri::CSS::XPathVisitorAlwaysUseBuiltins and XPathVisitorOptimallyUseBuiltins are deprecated. Prefer Nokogiri::CSS::XPathVisitor with appropriate constructor arguments. These classes will be removed in a future version of Nokogiri.
