From 6302bf2ebe8d4807ede5ac9b8602c92ed336e5bd Mon Sep 17 00:00:00 2001 From: "U.Nakamura" Date: Mon, 19 Jun 2023 20:49:09 +0900 Subject: merge revision(s) d2520b7b76759118071a16e6bca22726a5de9fb4: [Backport #19439] Marshal.load: restore instance variables on Regexp [Bug #19439] The instance variables were restore on the Regexp source, not the regexp itself. Unfortunately we have a bit of a chicken and egg problem. The source holds the encoding, and the encoding need to be set on the source to be able to instantiate the Regexp. So the instance variables have to be read on the `source`. To correct this we transfert the instance variables after instantiating the Regexp. The only way to avoid this would be to read the instance variable twice and rewind. --- marshal.c | 20 ++++++++++++++++++-- spec/ruby/core/marshal/shared/load.rb | 11 +++++++++++ 2 files changed, 29 insertions(+), 2 deletions(-) --- spec/ruby/core/marshal/shared/load.rb | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'spec/ruby') diff --git a/spec/ruby/core/marshal/shared/load.rb b/spec/ruby/core/marshal/shared/load.rb index b70bca55bf..3a1eb72676 100644 --- a/spec/ruby/core/marshal/shared/load.rb +++ b/spec/ruby/core/marshal/shared/load.rb @@ -803,6 +803,17 @@ describe :marshal_load, shared: true do new_obj_metaclass_ancestors[@num_self_class, 3].should == [Meths, UserRegexp, Regexp] end + + ruby_bug "#19439", ""..."3.3" do + it "restore the regexp instance variables" do + obj = Regexp.new("hello") + obj.instance_variable_set(:@regexp_ivar, [42]) + + new_obj = Marshal.send(@method, "\x04\bI/\nhello\x00\a:\x06EF:\x11@regexp_ivar[\x06i/") + new_obj.instance_variables.should == [:@regexp_ivar] + new_obj.instance_variable_get(:@regexp_ivar).should == [42] + end + end end describe "for a Float" do -- cgit v1.2.3
