--------------------------------------

             Summary: Thrift RSpec test suite fails with Ruby 2.4.x due to Fixnum deprecation
                 Key: THRIFT-4289
                 URL: https://issues.apache.org/jira/browse/THRIFT-4289
             Project: Thrift
          Issue Type: Bug
          Components: Ruby - Compiler, Ruby - Library
    Affects Versions: 0.10.0
         Environment: Thrift v0.10.0
ruby 2.4.0p0
CentOS Linux (3.10.0-514.26.2.el7.x86_64) 7
            Reporter: Jerzy J. Gangi


h3. Steps to reproduce:
1) Install ruby 2.4.x
2) Build Thrift with `./bootstrap.sh`, `./configure`, `make`, and `sudo make install`

h3. The RSpec suite will fail 3 errors:

{noformat}
Failures:

  1) Struct Thrift::Struct should support optional type-checking in Thrift::Struct.new
     Failure/Error: lambda { SpecNamespace::Hello.new(:greeting => 3) }.should raise_error(Thrift::TypeError, "Expected Types::STRING, received Fixnum for field greeting")
       expected Thrift::TypeError with "Expected Types::STRING, received Fixnum for field greeting", got #<Thrift::TypeError: Expected Types::STRING, received Integer for field greeting> with backtrace:
         # ./lib/thrift/types.rb:69:in `check_type'
         # ./lib/thrift/struct.rb:42:in `block in initialize'
         # ./lib/thrift/struct.rb:38:in `each'
         # ./lib/thrift/struct.rb:38:in `initialize'
         # ./spec/struct_spec.rb:230:in `new'
         # ./spec/struct_spec.rb:230:in `block (4 levels) in <top (required)>'
         # ./spec/struct_spec.rb:230:in `block (3 levels) in <top (required)>'
     # ./spec/struct_spec.rb:230:in `block (3 levels) in <top (required)>'

  2) Struct Thrift::Struct should support optional type-checking in field accessors
     Failure/Error: lambda { hello.greeting = 3 }.should raise_error(Thrift::TypeError, "Expected Types::STRING, received Fixnum for field greeting")
       expected Thrift::TypeError with "Expected Types::STRING, received Fixnum for field greeting", got #<Thrift::TypeError: Expected Types::STRING, received Integer for field greeting> with backtrace:
         # ./lib/thrift/types.rb:69:in `check_type'
         # ./lib/thrift/struct.rb:157:in `block in field_accessor'
         # ./spec/struct_spec.rb:241:in `block (4 levels) in <top (required)>'
         # ./spec/struct_spec.rb:241:in `block (3 levels) in <top (required)>'
     # ./spec/struct_spec.rb:241:in `block (3 levels) in <top (required)>'

  3) Thrift::Types type checking should give the Thrift::TypeError a readable message
     Failure/Error: lambda { Thrift.check_type(3, {:type => Thrift::Types::STRING}, :foo) }.should raise_error(Thrift::TypeError, msg)
       expected Thrift::TypeError with "Expected Types::STRING, received Fixnum for field foo", got #<Thrift::TypeError: Expected Types::STRING, received Integer for field foo> with backtrace:
         # ./lib/thrift/types.rb:69:in `check_type'
         # ./spec/types_spec.rb:101:in `block (4 levels) in <top (required)>'
         # ./spec/types_spec.rb:101:in `block (3 levels) in <top (required)>'
     # ./spec/types_spec.rb:101:in `block (3 levels) in <top (required)>'
{noformat}

h3. Cause
Starting in Ruby 2.4, ::Fixnum is deprecated. See https://bugs.ruby-lang.org/issues/12005

h4. Solution
In lib/rb/spec/struct_spec.rb, change
{noformat}
lambda { SpecNamespace::Hello.new(:greeting => 3) }.should raise_error(Thrift::TypeError, "Expected Types::STRING, received Fixnum for field greeting")
{noformat}
to
{noformat}
lambda { SpecNamespace::Hello.new(:greeting => 3) }.should raise_error(Thrift::TypeError, "Expected Types::STRING, received Integer for field greeting")
{noformat}
and
{noformat}
lambda { hello.greeting = 3 }.should raise_error(Thrift::TypeError, "Expected Types::STRING, received Fixnum for field greeting")
{noformat}
to
{noformat}
lambda { hello.greeting = 3 }.should raise_error(Thrift::TypeError, "Expected Types::STRING, received Integer for field greeting")
{noformat}
In lib/rb/spec/types_spec.rb, change:
{noformat}
msg = "Expected Types::STRING, received Fixnum for field foo"
{noformat}
to
{noformat}
msg = "Expected Types::STRING, received Integer for field foo"
{noformat}
and
{noformat}
msg = "Expected Types::STRING, received Fixnum for field foo.element"
{noformat}
to
{noformat}
msg = "Expected Types::STRING, received Integer for field foo.element"
{noformat}

RSpec suite will then pass, and `sudo make install` will exit successfully.
