------------------------------------
Summary: Removing dead symlinks fails with jruby on ppc64 platform
Key: JRUBY-6315
URL: https://jira.codehaus.org/browse/JRUBY-6315
Project: JRuby
Issue Type: Bug
Reporter: Vinutha Nayak
Assignee: Thomas E Enebo
Failing testcase : test_file.rb ( part of testcase shipped with ruby 1.7.0
source ) . I have simplified it to contain only the failing part.
{noformat}
require 'test/unit'
class TestMethodSymlink < Test::Unit::TestCase
def test_require_symlink
# Create a ruby file that sets a global variable to its view of __FILE__
f = File.open("real_file.rb", "w")
f.write("$test_require_symlink_filename=__FILE__")
f.close()
system("ln -s real_file.rb linked_file.rb")
assert(File.symlink?("linked_file.rb"))
# JRUBY-5167 - Test that symlinks don't effect __FILE__ during load or
require
# Note: This bug only manifests for absolute paths that point to symlinks.
abs_path = File.join(Dir.pwd, "real_file.rb")
require abs_path
assert_equal($test_require_symlink_filename, abs_path)
abs_path_linked = File.join(Dir.pwd, "linked_file.rb")
require abs_path_linked
assert_equal($test_require_symlink_filename, abs_path_linked)
load abs_path_linked
assert_equal($test_require_symlink_filename, abs_path_linked)
ensure
File.delete("real_file.rb")
File.delete("linked_file.rb")
end
end
{noformat}
When running with Java 7 we get the following error :
{noformat}
E
Finished in 0.311 seconds.
1) Error:
test_require_symlink(TestMethodSymlink):
Errno::ENOENT: No such file or directory - linked_file.rb

Basically here the issue is that Jruby is not able to recognise the dead
symlinks.
Seems like it is failing at the following part of ruby code :
{noformat}
boolean isSymlink = RubyFileTest.symlink_p(recv, filename).isTrue();
// Broken symlinks considered by exists() as non-existing,
// so we need to check for symlinks explicitly.
if (!lToDelete.exists() && !isSymlink) {
throw runtime.newErrnoENOENTError(filename.getUnicodeValue());
<----- exception is thrown here
}
{noformat}
the symlink_p() should be returning *false* in the current scenario on ppc64
bit machine .
Could you please check on this ? I have tested with
build@http://ci.jruby.org/snapshots/master and I see the same failure with it
too .Failure is seen both with java6 and java7 latest builds.
