Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Tim Peters 0891ac017d The 'p' (Pascal string) pack code acts unreasonably when the string size
and count exceed 255.  Changed to preserve as much of the string as
possible (instead of count%256 characters).

Tim Peters 3eec38af37 Added "i" and "l" to the list of std-mode struct codes that don't range-
check correctly on pack().  While these were checking OK on my 32-bit box,
Mark Favas reported failures on a 64-bit box (alas, easy to believe).

Tim Peters 17e17d4406 Generalize the new qQ std-mode tests to all int codes (bBhHiIlLqQ).
Unfortunately, the std-mode bBhHIL codes don't do any range-checking; if
and when some of those get fixed, remove their letters from the
IntTester.BUGGY_RANGE_CHECK string.  In the meantime, a msg saying that
range-tests are getting skipped is printed to stdout whenever one is
skipped.

Tim Peters da9c5b35a3 The new {b,l}p_{u,}longlong() didn't check get_pylong()'s return for NULL.
Repaired that, and added appropriate tests for it to test_struct.py.

Tim Peters 7a3bfc3a47 Added q/Q standard (x-platform 8-byte ints) mode in struct module.
This completes the q/Q project.

longobject.c _PyLong_AsByteArray:  The original code had a gross bug:
the most-significant Python digit doesn't necessarily have SHIFT
significant bits, and you really need to count how many copies of the sign
bit it has else spurious overflow errors result.

test_struct.py:  This now does exhaustive std q/Q testing at, and on both
sides of, all relevant power-of-2 boundaries, both positive and negative.

NEWS:  Added brief dict news while I was at it.

Tim Peters c533edceb1 Renamed some stuff to tell the truth about what it does. 2001-06-10 23:52:59 +00:00
Tim Peters 7b9542a3f7 Initial support for 'q' and 'Q' struct format codes: for now, only in
native mode, and only when config #defines HAVE_LONG_LONG.  Standard mode
will eventually treat them as 8-byte ints across all platforms, but that
likely requires a new set of routines in longobject.c first (while
sizeof(long) >= 4 is guaranteed by C, there's nothing in C we can rely
on x-platform to hold 8 bytes of int, so we'll have to roll our own;
I'm thinking of a simple pair of conversion functions, Python long
to/from sized vector of unsigned bytes; that may be useful for GMP
conversions too; std q/Q would call them with size fixed at 8).

test_struct.py:  In addition to adding some native-mode 'q' and 'Q' tests,
got rid of unused code, and repaired a non-portable assumption about
native sizeof(short) (it isn't 2 on some Cray boxes).

libstruct.tex:  In addition to adding a bit of 'q'/'Q' docs (more needed
later), removed an erroneous footnote about 'I' behavior.

Fred Drake 132dce2246 Update the code to better reflect recommended style:
Use != instead of <> since <> is documented as "obsolescent".
Use "is" and "is not" when comparing with None or type objects.

Fred Drake 004d5e6880 Make reindent.py happy (convert everything to 4-space indents!). 2000-10-23 17:22:08 +00:00
Guido van Rossum 41360a4696 Mass check-in after untabifying all files that need it. 1998-03-26 19:42:58 +00:00
Guido van Rossum 04ebf5ca5d Change the ``calcsize*3'' test to be portable to 64-bit machines. 1997-01-03 19:00:37 +00:00
Guido van Rossum 420c11c6aa Added f/d tests for specific byte orders. 1997-01-03 00:09:46 +00:00
Guido van Rossum 2a37850273 Exercise the new feature set somewhat.
Use TestFailed exception and verbose flag from test_support module.
