[ruby-core:112146] [Ruby master Bug#19394] cvars in instance of cloned class point to source class's cvars even after class_variable_set on clone
by jamescdavis (James Davis) 25 Jul '23

25 Jul '23

Issue #19394 has been reported by jamescdavis (James Davis). ---------------------------------------- Bug #19394: cvars in instance of cloned class point to source class's cvars even after class_variable_set on clone https://bugs.ruby-lang.org/issues/19394 * Author: jamescdavis (James Davis) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x86_64-darwin21] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- This unexpected change in behavior happens between Ruby 3.0.x and 3.1.x. In Ruby >= 3.1, when a class with a cvar is cloned (or duped), the cvar in instances of the cloned class continues to point to the source class’s cvar after the clone has its cvar updated with `class_variable_set`. In Ruby < 3.1, the cloned class instance points to the updated cvar, as expected. It seems likely that this is a bug in the [cvar cache](https://bugs.ruby-lang.org/issues/17763) introduced in Ruby 3.1. Repro: ```rb class Foo @@bar = 'bar' def print_bar puts "#{self.class.name} (from instance): #{@@bar} #{@@bar.object_id}" end end foo_bar = Foo.class_variable_get(:@@bar) puts "Foo (class_variable_get): #{foo_bar} #{foo_bar.object_id}" Foo.new.print_bar FooClone = Foo.clone FooClone.class_variable_set(:@@bar, 'bar_clone') foo_clone_bar = FooClone.class_variable_get(:@@bar) puts "FooClone (class_variable_get): #{foo_clone_bar} #{foo_clone_bar.object_id}" FooClone.new.print_bar ``` Ruby 3.0.5: ``` Foo (class_variable_get): bar 60 Foo (from instance): bar 60 FooClone (class_variable_get): bar_clone 80 FooClone (from instance): bar_clone 80 ``` Ruby 3.1.3, 3.2.0: ``` Foo (class_variable_get): bar 60 Foo (from instance): bar 60 FooClone (class_variable_get): bar_clone 80 FooClone (from instance): bar 60 ``` Something similar happens when there are multiple clones and a cvar that the source class does not have defined is set on the clones. In this case, the cvars in instances of the clones all point to the first clone’s cvar. Repro: ```rb class Foo def print_bar puts "#{self.class.name} (from instance): #{@@bar} #{@@bar.object_id}" end end Foo1 = Foo.clone Foo2 = Foo.clone Foo3 = Foo.clone Foo1.class_variable_set(:@@bar, 'bar1') Foo2.class_variable_set(:@@bar, 'bar2') Foo3.class_variable_set(:@@bar, 'bar3') foo1_bar = Foo1.class_variable_get(:@@bar) foo2_bar = Foo2.class_variable_get(:@@bar) foo3_bar = Foo3.class_variable_get(:@@bar) puts "Foo1 (class_variable_get): #{foo1_bar} #{foo1_bar.object_id}" puts "Foo2 (class_variable_get): #{foo2_bar} #{foo2_bar.object_id}" puts "Foo3 (class_variable_get): #{foo3_bar} #{foo3_bar.object_id}" Foo1.new.print_bar Foo2.new.print_bar Foo3.new.print_bar ``` Ruby 3.0.5: ``` Foo1 (class_variable_get): bar1 60 Foo2 (class_variable_get): bar2 80 Foo3 (class_variable_get): bar3 100 Foo1 (from instance): bar1 60 Foo2 (from instance): bar2 80 Foo3 (from instance): bar3 100 ``` Ruby 3.1.3, 3.2.0: ``` Foo1 (class_variable_get): bar1 60 Foo2 (class_variable_get): bar2 80 Foo3 (class_variable_get): bar3 100 Foo1 (from instance): bar1 60 Foo2 (from instance): bar1 60 Foo3 (from instance): bar1 60 ``` -- https://bugs.ruby-lang.org/

Issue #19630 has been reported by postmodern (Hal Brodigan). ---------------------------------------- Feature #19630: [RFC] Deprecate `Kernel.open("|command-here")` due to frequent security issues https://bugs.ruby-lang.org/issues/19630 * Author: postmodern (Hal Brodigan) * Status: Open * Priority: Normal ---------------------------------------- `Kernel.open()` is the source of numerous [1] security [2] issues [3], due to the fact that it can be used to execute commands if given a String argument of the form `"|command-here"`. However, in most uses of `Kernel.open()` the developer appears to either want to open a local file, or if 'open-uri' was explicitly required open a remote URI. We should deprecate calling `Kernel.open()` with a `"|command-here"` style arguments, with a warning message instructing the developer to use `IO.popen()` instead. Eventually, support for `Kernel.open("|command-here")` could be removed completely, in favor of having the developer explicitly call `IO.popen()` or `URI.open()`.

[ruby-core:111565] [Ruby master Bug#19293] The new Time.new(String) API is nice... but we still need a stricter version of this
by matsuda (Akira Matsuda) 23 Jul '23

Issue #19293 has been reported by matsuda (Akira Matsuda). ---------------------------------------- Bug #19293: The new Time.new(String) API is nice... but we still need a stricter version of this https://bugs.ruby-lang.org/issues/19293 * Author: matsuda (Akira Matsuda) * Status: Open * Priority: Normal * ruby -v: ruby 3.3.0dev (2023-01-01T07:39:00Z master 542e984d82) +YJIT [arm64-darwin21] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- The Ruby 3.2 style `Time.new(String)` API works very well so far, but since the original `Time.new(Integer, Integer, Integer...)` API actually accepts String objects as its arguments, there's one ambiguous case as follows: `Time.new('20230123') #=> 20230123-01-01 00:00:00 +0900` Then the problem that I'm facing is that we cannot tell if `Time.new` would parse the given String as ISO8601-ish or just a year, and in order to avoid this ambiguity, we still need to somehow parse the String beforehand in our application side (like we're doing this way in Ruby on Rails https://github.com/rails/rails/blob/c49b8270/activemodel/lib/active_model/t…) then dispatch to the new `Time.new` only when the String is validated to be conforming the ISO format. Otherwise, if we just optimistically pass in given Strings to `Time.new`, we'll occasionally get a Time object with an unintended buggy value. Therefore, it unfortunately seems that my feature request on #16005 still continues... I have to keep proposing that we need either of the following: 1. A trustworthy version of ISO8601 parser method perhaps with another name than `.new` that accepts strict ISO8601-ish String only (but with the T delimiter, I still don't know what the proper name of this format is). 2. Change `Time.new(Integer-ish, Integer-ish, Integer-ish...)` not to accept Integer-ish Strings but to accept only Integers. But I can imagine that this direction is very unlikely acceptable, due to the incompatibility. -- https://bugs.ruby-lang.org/

[ruby-core:112926] [Ruby master Misc#19535] Instance variables order is unpredictable on objects with `OBJ_TOO_COMPLEX_SHAPE_ID`
by byroot (Jean Boussier) 22 Jul '23

Issue #19535 has been reported by byroot (Jean Boussier). ---------------------------------------- Misc #19535: Instance variables order is unpredictable on objects with `OBJ_TOO_COMPLEX_SHAPE_ID` https://bugs.ruby-lang.org/issues/19535 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal ---------------------------------------- ### Context I've been helping the Mastodon folks in investigating a weird Marshal deserialization bug they randomly experience since they upgraded to Ruby 3.2: https://github.com/mastodon/mastodon/issues/23644 Ultimately the bug comes from a circular dependency issues in the object graph that is serialized when one call `Marshal.dump` on an `ActiveRecord::Base` object. A simplified reproduction to better explain the problem is: ```ruby class Status def normal_order @attributes = { id: 42 } @relations = { self => 1 } self end def inverse_order @relations = nil @attributes = { id: 42 } @relations = { self => 1 } self end def hash @attributes.fetch(:id) end end s = Marshal.load(Marshal.dump(Status.new.normal_order)) s = Marshal.load(Marshal.dump(Status.new.inverse_order)) ``` In short, that `Status` object is both the top level object, and is referenced as a key in a hash, in that same payload. It also defined a custom `#hash` method, that requires some other attribute to be set. It all "works" as long as `@attributes` is dumped before `@relations`. ### Problem The above micro-reproduction uses two different shapes to demonstrate the ordering issues, but in both case the ordering is predictable. However if you generate too many shapes from a single class, it will be marked as `TOO_COMPLEX` and future instance will have their instance variables backed by an `id_table`, which is unordered, and will cause a similar issue. I definitely consider this a bug on the Rails side, and I will do what I can so that Rails doesn't depend on that implicit ordering. However it's unlikely we'll be able to fix older version, and other users may run into this issue when upgrading to Ruby 3.2, so I think it may be worth to try to preserve some sort of predicable ordering, at least for a few more versions. Additionally, debugging it was made particularly difficult, because it would work fine initially, and then break after enough shapes had been generated. Generally speaking I think such semi-predictable behavior is much worse than a fully random behavior (similar to how Go randomize keys order in their maps). ### Historical behavior On Ruby 3.1 and older, the instance variables ordering was defined by the order in which each ivar appeared for the very first time: ```ruby class Foo def set @a = 1 @b = 2 @c = 3 self end def inverse_order @c = 3 @b = 2 @a = 1 self end end p Foo.new.set.instance_variables # => [:@a, :@b, :@c] p Foo.new.inverse_order.instance_variables # => [:@a, :@b, :@c] ``` This means that the order could be different from once execution of the program to another, but would remain stable inside a single process. On 3.2, it's now defined by the order in which each ivar appeared in that specific object instance: ```ruby [:@a, :@b, :@c] [:@c, :@b, :@a] ``` Except, if the object is backed by an `id_table`, in which case it's fully unpredictable. ### Possible changes I discussed this with @tenderlovemaking, and he suggested we could change the `id_table` for an `st_table` so that the ordering could be predictable again, and would behave like objects with a non-complex shape. Another possibility would be to preserve the observable behavior of 3.1 and older. Or of course we could clearly specify that the ordering is random, but if so I think it would be wise to make it always random so that this class of bugs has a much higher chance to be caught early in testing rather than in production. cc @Eregon as I presume this has implications on TruffleRuby as well. -- https://bugs.ruby-lang.org/
