120 * We use a "smart" matching algorithm that allows us to detect partial improvements
121 * in conformance. Specifically, two running indices are kept, one through the actual
122 * path and one through the expected path. The actual path index increases unless there is
123 * no match and the todo field of the appropriate path_test_t element is 2. Similarly,
124 * if the wine_entries_preceding field of the appropriate path_test_t element is non-zero,
125 * the expected path index does not increase for that many elements as long as there
126 * is no match. This allows us to todo_wine extra path elements that are present only
127 * on wine but not on native and vice versa.
129 * Note that if expected_size is zero and the WINETEST_DEBUG environment variable is
130 * greater than 2, the trace() output is a C path_test_t array structure, useful for making
131 * new tests that use this function.
