Daniel Berger created JRUBY-6295:
------------------------------------
Summary: Dir.chdir, $HOME and $LOGDIR behavior
Key: JRUBY-6295
URL: https://jira.codehaus.org/browse/JRUBY-6295
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.6.5
Environment: jruby 1.6.5 (ruby-1.8.7-p330) (2011-10-25 9dcd388) (Java
HotSpot(TM) 64-Bit Server VM 1.6.0_29) [darwin-x86_64-java]
Reporter: Daniel Berger
Priority: Minor
This is a followup to jruby-673. In MRI, Dir.chdir defaults to $HOME if no
directory is specified. That was fixed. However, if $HOME is not set, it should
default to $LOGDIR. If neither $HOME nor $LOGDIR are set, it should raise an
error with a specific error message. Take a look at dir_s_chdir in dir.c for
more information.
{noformat}
test "chdir without an argument defaults to LOGDIR if HOME is not set" do
ENV['HOME'] = nil
ENV['LOGDIR'] = Dir.pwd
Dir.chdir
assert_equal(ENV['LOGDIR'], Dir.pwd)
end
test "chdir raises an error if both the HOME and LOGDIR env variables are nil"
do
ENV['HOME'] = nil
ENV['LOGDIR'] = nil
assert_raise(ArgumentError){ Dir.chdir }
assert_raise_message("HOME/LOGDIR not set"){ Dir.chdir }
end
