Daniel Stutzbach | c944cfc | 2010-09-21 21:08:09 +0000 | [diff] [blame] | 398 | # This test creates a complex arrangement of frozensets and |
| 399 | # compares the pretty-printed repr against a string hard-coded in |
| 400 | # the test. The hard-coded repr depends on the sort order of |
| 401 | # frozensets. |
| 402 | # |
| 403 | # However, as the docs point out: "Since sets only define |
| 404 | # partial ordering (subset relationships), the output of the |
| 405 | # list.sort() method is undefined for lists of sets." |
| 406 | # |
| 407 | # In a nutshell, the test assumes frozenset({0}) will always |
| 408 | # sort before frozenset({1}), but: |
| 409 | # |
| 410 | # >>> frozenset({0}) < frozenset({1}) |
| 411 | # False |
| 412 | # >>> frozenset({1}) < frozenset({0}) |
| 413 | # False |
| 414 | # |
| 415 | # Consequently, this test is fragile and |
| 416 | # implementation-dependent. Small changes to Python's sort |
| 417 | # algorithm cause the test to fail when it should pass. |
