 | |
|         If this test failed, you probably added a new "format unit"
 | |
|         in Python/getargs.c, but neglected to update our poor friend
 | |
|         skipitem() in the same file.  (If so, shame on you!)
 | |
| 
 | |
|         With a few exceptions**, this function brute-force tests all
 | |
|         printable ASCII*** characters (32 to 126 inclusive) as format units,
 | |
|         checking to see that PyArg_ParseTupleAndKeywords() return consistent
 | |
|         errors both when the unit is attempted to be used and when it is
 | |
|         skipped.  If the format unit doesn't exist, we'll get one of two
 | |
|         specific error messages (one for used, one for skipped); if it does
 | |
|         exist we *won't* get that error--we'll get either no error or some
 | |
|         other error.  If we get the specific "does not exist" error for one
 | |
|         test and not for the other, there's a mismatch, and the test fails.
 | |
| 
 | |
|            ** Some format units have special funny semantics and it would
 | |
|               be difficult to accommodate them here.  Since these are all
 | |
|               well-established and properly skipped in skipitem() we can
 | |
|               get away with not testing them--this test is really intended
 | |
