Roberto Ierusalimschy bc84180d12 error message in 'os.rename' does not include file name, because error 
may be caused both by 'fromname' or 'toname'
 2012-10-19 12:54:02 -03:00
Roberto Ierusalimschy ad5da6ba14 API functions get acceptable indices except when not possible (when 
they modify the value at that index) + new macro 'ispseudo' +
specific test 'api_checkstackindex'
 2012-10-19 12:52:46 -03:00
Roberto Ierusalimschy 86b39206d9 open upvalues cannot be old if thread is not old; when thread is old, 
their list is not traversed anymore, and therefore can contain dead
elements.
