From c14cbf31e26b5749623947727ffac64817b5bb5f Mon Sep 17 00:00:00 2001 From: Leonardo Rodrigues de Mello Date: Mon, 9 Sep 2013 10:27:54 -0300 Subject: bug # 20681 delete() function should not remove elements from original list MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The setup: list with 3 elements, delete one: $test_list = [‘a’, ‘b’, ‘c’] $test_deleted = delete($test_list, ‘a’) Print out the elements in ‘test_deleted’: notify { ‘group_output2’: withpath => true, name => “$cfeng::test_deleted”, } Notice: /Stage[main]/Syslog/Notify[group_output2]/message: bc Good! Run-on output shows that ‘a’ was deleted Print out the elements in ‘test_list’: notify { ‘group_output1’: withpath => true, name => “$cfeng::test_list”, } Notice: /Stage[main]/Syslog/Notify[group_output1]/message: bc WHAT!? 'a' was deleted from ‘test_list’ as well! Expected abc as output! This behaviour is confirmed for string, hash and array. This is fixed on this commit, I had added two spec tests to cover that cases. bug #20681 spec test for delete() function. I had forgot in the last commit the spec test for hash in the delete function. bug # 20681 delete() function change aproach. Instead of rejecting elements from the original list, we use collection = arguments[0].dup . then latter we could continue to use delete and gsub! on collection without impact on original argument. this is a better solution than the previous one, and works on ruby 1.8.7, 1.9.3 and 2.0.0. The previous solution does not work on ruby 1.8.7. delete function remove typo whitespace. fix typo whitespaces. --- spec/unit/puppet/parser/functions/delete_spec.rb | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'spec') diff --git a/spec/unit/puppet/parser/functions/delete_spec.rb b/spec/unit/puppet/parser/functions/delete_spec.rb index 2f29c93..06238f1 100755 --- a/spec/unit/puppet/parser/functions/delete_spec.rb +++ b/spec/unit/puppet/parser/functions/delete_spec.rb @@ -35,4 +35,22 @@ describe "the delete function" do result.should(eq({ 'a' => 1, 'c' => 3 })) end + it "should not change origin array passed as argument" do + origin_array = ['a','b','c','d'] + result = scope.function_delete([origin_array, 'b']) + origin_array.should(eq(['a','b','c','d'])) + end + + it "should not change the origin string passed as argument" do + origin_string = 'foobarbabarz' + result = scope.function_delete([origin_string,'bar']) + origin_string.should(eq('foobarbabarz')) + end + + it "should not change origin hash passed as argument" do + origin_hash = { 'a' => 1, 'b' => 2, 'c' => 3 } + result = scope.function_delete([origin_hash, 'b']) + origin_hash.should(eq({ 'a' => 1, 'b' => 2, 'c' => 3 })) + end + end -- cgit v1.2.3
