From 17f9ad40f64b0a7d54210964b5341f9c44fa4613 Mon Sep 17 00:00:00 2001 From: ko1 Date: Tue, 7 Nov 2017 14:23:58 +0000 Subject: [PATCH] disable GC. * test/ruby/test_io.rb (test_write_no_garbage): malloc can cause GC and it will reduce string object counts. So disable GC during this test. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60699 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- test/ruby/test_io.rb | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) diff --git a/test/ruby/test_io.rb b/test/ruby/test_io.rb index 3ffc7281df..a0a574e69d 100644 --- a/test/ruby/test_io.rb +++ b/test/ruby/test_io.rb @@ -3651,10 +3651,15 @@ __END__ ObjectSpace.count_objects(res) # creates strings on first call [ 'foo'.b, '*' * 24 ].each do |buf| with_pipe do |r, w| - before = ObjectSpace.count_objects(res)[:T_STRING] - n = w.write(buf) - s = w.syswrite(buf) - after = ObjectSpace.count_objects(res)[:T_STRING] + GC.disable + begin + before = ObjectSpace.count_objects(res)[:T_STRING] + n = w.write(buf) + s = w.syswrite(buf) + after = ObjectSpace.count_objects(res)[:T_STRING] + ensure + GC.enable + end assert_equal before, after, "no strings left over after write [ruby-core:78898] [Bug #13085]: #{ before } strings before write -> #{ after } strings after write" assert_not_predicate buf, :frozen?, 'no inadvertent freeze'
