File#delete can't delete broken symlinks
----------------------------------------
Key: JRUBY-1920
URL: http://jira.codehaus.org/browse/JRUBY-1920
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-delete-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`
# Attempt to delete the broken link
File.delete('link-to-test-file')
# Check that it's deleted
`ls -l link-to-test-file`
{noformat}
MRI prints:
ls: link-to-test-file: No such file or directory
(which means that the broken symlink was successfully deleted)
JRuby prints:
No such file or directory - "link-to-test-file" (Errno::ENOENT)
(an attempt to delete the broken symlink leads to the exception, the
symlink is NOT removed).
This leads to some hard-to-understand rubyspec failures from time to time.
The proposed patch fixes the problem.
NOTE: This issue should be fixes after JRUBY-1919, so that File#symlink?
works correctly, since in this patch we rely on that.
