| Summary | 0000152: replace_program() and virtual variables | ||||
| Description | Short: replace_program() and virtual variables From: Lars, Zonk Date: 2003-01-19 Type: Bug State: New replace_program() can replace with a program only if it either doesn't have virtually inherited variables, or is the first program inherited. Reason is that replace_program() expects the variables of the program in one block, starting at variable_index_offset. However, with virtual inherites the virtually inherited variables are collected in a block at the beginning of the variable block, so that replace_program() extracts the wrong variables during the replacement. Only if the replaced program happens to be the first inherited program, the variable_index_offset is 0 and the extraction code by accident does the right thing. The proper solution would be to use the inheritance/variable information to extract and rebuild both virtual and nonvirtual variable blocks; however at the moment I don't understand the structure well enough to do it. Here are the test programs: --- test.c --- inherit "/test_a"; inherit "/test_c"; --- test_a.c --- string target_program = "test_a"; --- test_c.c --- virtual inherit "/test_b"; string var2 = "test_c"; void create() { replace_program("/test_c"); set_var("content"); call_out( "write_var", 2 ); } --- test_b.c --- string var; void set_var( string value ) { var = value; write( "object="+object_name()+" [set_var()] var="+var+"\n" ); } public void write_var() { write( "object="+object_name()+" [write_var()] var="+var+"\n" ); } ------ | ||||
