Michael Stockton commented on THRIFT-1183:
------------------------------------------
It should work. We added the #ord method in thrift/core_ext/fixnum.rb for pre
1.8.7 clients.
> Pure-ruby CompactProtocol raises ArgumentError when deserializing under Ruby
> 1.9

> Key: THRIFT-1183
> URL: https://issues.apache.org/jira/browse/THRIFT-1183
> Project: Thrift
> Issue Type: Bug
> Components: Ruby - Library
> Affects Versions: 0.6.1
> Environment: OS X 10.6 i686 / Ruby 1.9.2
> Reporter: Ilya Maykov
> Attachments: patch-THRIFT-1183.txt

> While testing my fix for THRIFT-1182 with various combinations of
> native/non-native ruby and binary/compact protocols, I stumbled upon a bug in
> the pure-ruby implementation of CompactProtocol.
> In lib/thrift/protocol/compact_protocol.rb line 306:
> ...
> val = dat[0]
> if (val > 0x7f)
> ...
> Here, dat is a string, so dat[0] returns a Fixnum in Ruby 1.8.7 but a string
> of size 1 in Ruby 1.9.2. The conditional compares dat[0] with 0x7f, which
> raises the following error in 1.9.2:
> /Users/ilyam/.rvm/gems/ruby-1.9.2-p180/gems/thrift-0.6.0/lib/thrift/protocol/compact_protocol.rb:307:in
> `>': comparison of String with 127 failed (ArgumentError)
> from

> from
> /Users/ilyam/.rvm/gems/ruby-1.9.2-p180/gems/thrift-0.6.0/lib/thrift/serializer/deserializer.rb:29:in
> `deserialize'
> The solution is a one-line fix, patch will be attached shortly.
