[ruby-core:111448] [Ruby master Bug#19266] URI::Generic should use URI::RFC3986_PARSER instead of URI::DEFAULT_PARSER
by gareth (Gareth Adams) 22 Jul '24

Issue #19266 has been reported by gareth (Gareth Adams). ---------------------------------------- Bug #19266: URI::Generic should use URI::RFC3986_PARSER instead of URI::DEFAULT_PARSER https://bugs.ruby-lang.org/issues/19266 * Author: gareth (Gareth Adams) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [arm64-darwin21] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- In June 2014, [`uri/common` was updated][1] to introduce a RFC3986-compliant parser (`URI::RFC3986_PARSER`) as an alternative to the previous RFC2396 parser, and common methods like `URI()` were updated to use that new parser by default. The only methods in `common` not updated were [`URI.extract` and `URI.regexp`][2] which are marked as obsolete. (The old parser was kept in the `DEFAULT_PARSER` constant despite it not being the default for those methods, presumably for backward compatibility.) However, similar [methods called on `URI::Generic`][3] were never updated to use this new parser. This means that methods like `URI::Generic.build` fail when given input that succeeds normally, and this also affects subclasses like URI::HTTP: ``` $ pry -r uri -r uri/common -r uri/generic [1] pry(main)> URI::Generic.build(host: "underscore_host.example") URI::InvalidComponentError: bad component(expected host component): underscore_host.example from /Users/gareth/.asdf/installs/ruby/3.1.3/lib/ruby/3.1.0/uri/generic.rb:591:in `check_host' [2] pry(main)> URI::HTTP.build(host: "underscore_host.example") URI::InvalidComponentError: bad component(expected host component): underscore_host.example from /Users/gareth/.asdf/installs/ruby/3.1.3/lib/ruby/3.1.0/uri/generic.rb:591:in `check_host' [3] pry(main)> URI("http://underscore_host.example") => #<URI::HTTP http://underscore_host.example> ``` `URI::Generic.new` allows a configurable `parser` positional argument to override the class' default parser, but other factory methods like `.build` don't allow this override. Arguably this doesn't cause problems because at least in the case above, the URI can be built with the polymorphic constructor, but having the option to build URIs from explicit named parts is useful, and leaving the outdated functionality in the `Generic` class is ambiguous. It's possible that the whole Generic class and its subclasses aren't intended to be used directly how I'm intending here, but there's nothing I could see that suggested this is the case. I'm not aware of the entire list of differences between RFC2396 and RFC3986. The relevant difference here is that in RFC2396 an individual segment of a host ([`domainlabel`s][4]) could only be `alphanum | alphanum *( alphanum | "-" ) alphanum`, whereas RFC3986 allows [hostnames][5] to include any of `ALPHA / DIGIT / "-" / "." / "_" / "~"`. It's possible that other differences might cause issues for developers, but since this has gone over 8 years without anyone else caring about this, this is definitely not especially urgent.

Issue #19619 has been reported by okuramasafumi (Masafumi OKURA). ---------------------------------------- Bug #19619: Endless method definition with parameters for an instance given as numbered parameters doesn't work https://bugs.ruby-lang.org/issues/19619 * Author: okuramasafumi (Masafumi OKURA) * Status: Open * Priority: Normal * ruby -v: 3.2.2 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- This works: ```ruby class Foo def bar(baz) = 'foo' end p Foo.new.bar('baz') ``` This also works: ```ruby o = Object.new o.tap { |obj| def obj.bar(baz) = 'foo' } p o.bar('baz') ``` Even this works: ```ruby o = Object.new o.tap { def _1.bar = 'foo' } p o.bar ``` But this DOESN'T work: ```ruby o = Object.new o.tap { def _1.bar(baz) = 'foo' } p o.bar('baz') ``` So, when we define a method with parameters on an instance given as numbered parameters, it doesn't work. If we change one condition (definition way, parameter existence, and so on), it works. -- https://bugs.ruby-lang.org/

[ruby-core:111306] [Ruby master Feature#19236] Allow to create hashes with a specific capacity from Ruby
by byroot (Jean Boussier) 07 Jul '24

Issue #19236 has been reported by byroot (Jean Boussier). ---------------------------------------- Feature #19236: Allow to create hashes with a specific capacity from Ruby https://bugs.ruby-lang.org/issues/19236 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal * Target version: 3.3 ---------------------------------------- Followup on [Feature #18683] which added a C-API for this purpose. Various protocol parsers such as Redis `RESP3` or `msgpack`, have to create hashes, and they know the size in advance. For efficiency, it would be preferable if they could directly allocate a Hash of the necessary size, so that large hashes wouldn't cause many re-alloccations and re-hash. `String` and `Array` both already offer similar APIs: ```ruby String.new(capacity: XXX) Array.new(XX) / rb_ary_new_capa(long) ``` However there's no such public API for Hashes in Ruby land. ### Proposal I think `Hash` should have a way to create a new hash with a `capacity` parameter. The logical signature of `Hash.new(capacity: 1000)` was deemed too incompatible in [Feature #18683]. @Eregon proposed to add `Hash.create(capacity: 1000)`. -- https://bugs.ruby-lang.org/

[ruby-core:115595] [Ruby master Bug#20043] `defined?` checks for method existence but only sometimes

Issue #20043 has been reported by tenderlovemaking (Aaron Patterson). ---------------------------------------- Bug #20043: `defined?` checks for method existence but only sometimes https://bugs.ruby-lang.org/issues/20043 * Author: tenderlovemaking (Aaron Patterson) * Status: Open * Priority: Normal * ruby -v: ruby 3.3.0dev (2023-12-05T21:25:34Z master 56eccb350b) [arm64-darwin23] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- When an expression is passed to `defined?`, it will _sometimes_ check if a method in a sub-expression is defined and sometimes it won't. For example: ``` $ ./miniruby -e'p defined?(a)' nil $ ./miniruby -e'p defined?([a])' nil ``` In the above case, Ruby will check whether or not the method `a` is defined, and it returns `nil`. However, if you use a splat, it will not check: ``` $ ./miniruby -e'p defined?([*a])' "expression" ``` The same thing seems to happen with method parameters: ``` $ ./miniruby -e'p defined?(itself)' "method" $ ./miniruby -e'p defined?(itself(a))' nil $ ./miniruby -e'p defined?(itself(*a))' "method" ``` Oddly, `defined?` will check contents of arrays, but _won't_ check contents of hashes: ``` $ ./miniruby -e'p defined?([[[[a]]]])' nil $ ./miniruby -e'p defined?({ a => a })' "expression" ``` I think all of the cases that refer to `a` should check whether or not `a` is defined regardless of splats or hashes. -- https://bugs.ruby-lang.org/
