#1163: YAML datetime object with timezone seem to be parseable from mri/yarv but fails on macruby 0.8 -------------------------------+-------------------------------------------- Reporter: rff.rff@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 0.8 Component: MacRuby | Keywords: yaml, datetime -------------------------------+-------------------------------------------- the following YAML snippet {{{ date: 2011-02-21 00:00:00 +01:00 }}} is parsed properly by ruby 1.8.7, and 1.9.2 {{{ $ ruby -ryaml -e 'p YAML.load("date: 2011-02-21 00:00:00 +01:00")' {"date"=>Mon Feb 21 00:00:00 +0100 2011} }}} but macruby fails to read it properly failing with a message "argument out of range". This seem related to this code im YAML.rb {{{ def YAML.load(io) parsr = LibYAML::Parser.new(io) parsr.load end }}} which seems to indicate the problem lies in the libyaml bindings. Since I am currently unable to build macruby from source I can't tell if this is still a problem in trunk. I encountered this problem trying to install gems packaged on my box with GMT+1 timezone, so this may be a relatively widespread issue. -- Ticket URL: <http://www.macruby.org/trac/ticket/1163> MacRuby <http://macruby.org/>

#1160: Need ability to access errno from Ruby code --------------------------------------+------------------------------------- Reporter: warpflyght@… | Owner: lsansonetti@… Type: enhancement | Status: new Priority: minor | Milestone: Component: MacRuby | Keywords: --------------------------------------+------------------------------------- There doesn't appear to be a way to obtain the current thread's errno value without dropping into native code. The FFI library defines FFI.errno, but MacRuby's implementation of FFI is best characterized as a stub and thus hasn't implemented this functionality yet. If FFI is removed before 1.0 (see comments in #585), I'm not sure what the right place to expose errno would be. If it is not removed, implementing FFI.errno seems like the right thing to do. -- Ticket URL: <http://www.macruby.org/trac/ticket/1160> MacRuby <http://macruby.org/>
