File#symlink? returns false on broken symlinks
----------------------------------------------
Key: JRUBY-1919
URL: http://jira.codehaus.org/browse/JRUBY-1919
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1RC1
Environment: Latest JRuby 1.1RC1 from trunk.
Reporter: Vladimir Sizikov
Attachments: file-symlink-p-on-broken-symlink.patch
Consider the following example:
{noformat}
# First, clean everything
`rm -f test-file link-to-test-file`
# Create the file
`touch test-file`
# Create the link
`ln -s test-file link-to-test-file`
# Make the link broken
`rm test-file`
# Main checks:
p File.exists?('link-to-test-file')
p File.symlink?('link-to-test-file')
{noformat}
On MRI, it prints:
false
true
On JRuby, it prints:
false
false
Basically, File#symlink? returns false on broken, but existing symlink.
This leads to some hard-to-understand failures, (even dependent on the
execution order!) when running rubyspecs.
The proposed patch fixes the problem.
