with 'ungetc'
---------------------------------------------------------------------------------------------
Key: JRUBY-2203
URL: http://jira.codehaus.org/browse/JRUBY-2203
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1RC2
Environment: Latest JRuby 1.1RC2
Reporter: Vladimir Sizikov
Assignee: Vladimir Sizikov
Fix For: JRuby 1.1
Position changing methods should discard a char that was pushed back to the
stream via ungetc.
This example:
{noformat}
File.open('/tmp/blah1', 'w+') { |f| f.puts "HELLO" }
File.open('/tmp/blah1') do |file|
file.read(0)
file.ungetc(100)
p file.getc
file.ungetc(100)
file.pos = 0
p file.getc
file.ungetc(100)
file.rewind
p file.getc
file.ungetc(100)
file.seek(0)
p file.getc
end
{noformat}
MRI prints:
100
72
72
72
JRuby prints:
100
100
100
100
Fix is coming.
