File.truncate no longer elongate file
-------------------------------------
Key: JRUBY-963
URL: http://jira.codehaus.org/browse/JRUBY-963
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.0.0RC2
Environment: Windows XP / Java 1.6.0
Reporter: Peter K Chan
path = "new_file"
File.truncate(path, 10)
puts "Size is: " + File.size(path).to_s
In JRuby 1.0 RC2:
Size is: 0
In previous release:
Size is: 10
According to RubyDoc, File.truncate should:
"Truncates the file file_name to be at most integer bytes long. Not available
on all platforms."
No patch is attached, since the current JRuby behaviour is still correct, given
the documentation. However, if need be, the previous behavior can be restored
by using java.io.RandomAccessFile.setLength(), instead of the NIO's
setLength(), which does not elongate files.
