# == Tempfile (Patch)
# Tempfile has a horrible bug where it causes an IOError: closed stream in its
# finalizer, leading to intermittent application crashes with confusing stack
# traces. Here we monkey patch the fix into place. You can track the bug on
# ruby's redmine: http://redmine.ruby-lang.org/issues/show/3119
#
# The patch is slightly different for Ruby 1.8 and Ruby 1.9, both patches are
# included here.
class Tempfile # :nodoc:
# Tempfile has changes between 1.8.x and 1.9.x
# so we monkey patch separately
if RUBY_VERSION =~ /^1\.8/
def unlink
# keep this order for thread safeness
begin
File.unlink(@tmpname) if File.exist?(@tmpname)
@@cleanlist.delete(@tmpname)
@tmpname = nil
ObjectSpace.undefine_finalizer(self)
rescue Errno::EACCES
# may not be able to unlink on Windows; just ignore
end
end
alias delete unlink
# There is a patch for this, to be merged into 1.9 at some point.
# When that happens, we'll want to also check the RUBY_PATCHLEVEL
elsif RUBY_VERSION =~ /^1\.9/
def unlink
# keep this order for thread safeness
return unless @tmpname
begin
if File.exist?(@tmpname)
File.unlink(@tmpname)
end
# remove tmpname from remover
@data[0] = @data[2] = nil
@tmpname = nil
rescue Errno::EACCES
# may not be able to unlink on Windows; just ignore
end
end
alias delete unlink
