File.extname doesn't handle single period properly
--------------------------------------------------
Key: JRUBY-1017
URL: http://jira.codehaus.org/browse/JRUBY-1017
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.0.0RC2
Environment: OS X 10.4.9, Java 1.5
Reporter: Daniel Berger
Priority: Minor
The rule for File.extname is that a string with a single '.' (period) with
nothing preceding it, or nothing following it, returns an empty string. These
all fail currently:
{noformat}
assert_equal("", File.extname(".bashrc"))
assert_equal("", File.extname("."))
assert_equal("", File.extname("/."))
assert_equal("", File.extname(".."))
assert_equal("", File.extname(".foo."))
assert_equal("", File.extname("foo."))
{noformat}
