From 74bca55da9e509592bd04bc785b6eb86082f8cfe Mon Sep 17 00:00:00 2001 From: usa Date: Thu, 20 Dec 2012 09:52:46 +0000 Subject: merge revision(s) 38202,38238,38324,38326: [Backport #7527] * test/dl/test_func.rb (test_name_with_block, test_bind, test_qsort1): call unbind to release the callback closure because maximum number of callbacks is limited to DL::MAX_CALLBACK (== 5) with pure DL without Fiddle. * ext/dl/lib/dl/func.rb (DL::Function#unbind, #bound?): suppress NoMethodError when Fiddle is available. [ruby-core:50756] [Bug #7543] * test/dl/test_func.rb (test_bound*, test_unbind*): tests for the above. * ext/dl/lib/dl/func.rb (DL::Function#initialize, DL::Function#bind): ABI should be set by using CFunc#calltype even when Fiddle is used.
