"""
|
|
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
|
|
to catch *new* format units.
|
|
|
|
*** Python C source files must be ASCII. Therefore it's impossible
|
|
to have non-ASCII format units.
