Bug #5535: test/psych/test_yamldbm.rb, test/syck/test_yamldbm.rb
のDBM内部構造の順序に依存したテストがFailure

Author: Naohisa G.
Status: Open
Priority: Normal
Assignee:
Category: test
Target version:
ruby -v: ruby 2.0.0dev (2011-11-01) [x86_64-linux]

x86_64-linux, sparc-solaris2.10 での make test-all にて、以下のFailureが出ます。

YAML::DBM#shift の rdoc によると、

The order in which values are removed/returned is not guaranteed.
順序が不定であると明記されていますが、テストは特定の順序に依存して書かれているのが原因のようです。
YAML::DBM#to_a, YAML::DBM#values のテストも同様です。（ただしrdocに順序に関する記述は無い。）

Failure:
test_values(Syck::YAMLDBMTest) [/XXX/test/syck/test_yamldbm.rb:169]:
<[“b”, “d”]> expected but was
<[“d”, “b”]>.
Failure:
test_to_a(Syck::YAMLDBMTest) [/XXX/test/syck/test_yamldbm.rb:51]:
<[[“a”, “b”], [“c”, “d”]]> expected but was
<[[“c”, “d”], [“a”, “b”]]>.
Failure:
test_shift(Syck::YAMLDBMTest) [/XXX/test/syck/test_yamldbm.rb:100]:
<[“a”, “b”]> expected but was
