'%2147483647d' % -123 segfaults. This was because an integer overflow
in a comparison caused the string resize to be skipped. After fixing
the overflow, this could call _PyString_Resize() with a negative size,
so I (1) test for that and raise MemoryError instead; (2) also added a
test for negative newsize to _PyString_Resize(), raising SystemError
as for all bad arguments.
An identical bug existed in unicodeobject.c, of course.
Will backport to 2.2.2.
Immediate benefit: when you use "make -t" to avoid a global recompile
after a trivial header file touchup, Make will no longer create files
named all, oldsharedmods, and sharedmods.
(Not sure if I tracked down all such targets. Not sure if I care.)
refactor a bit and clean up.
M PyShell.py Cosmetic changes, delete blank lines, add # on some
blank lines.
M rpc.py Add more debugging capability
M run.py Add support for getting calltip from subprocess
Move import statements
Also fixed an error message -- %s argument has non-string str()
doesn't make sense for %r, so the error message now differentiates
between %s and %r.
because PyObject_Repr() and PyObject_Str() ensure that this can never
happen. Added a helpful comment instead.
sees a Unicode argument. Unfortunately this test was also executed
for %r, because %s and %r share almost all of their code. This meant
that, if u is a unicode object while repr(u) is an 8-bit string
containing ASCII characters, '%r' % u is a *unicode* string containing
only ASCII characters!
Fixed by executing the test only for %s.

initializing GNU readline, setlocale(LC_CTYPE, "") is called, which
changes the <ctype.h> macros to use the "default" locale (which isn't
the *initial* locale -- the initial locale is the "C" locale in which
only ASCII characters are printable). When the default locale is e.g.
Latin-1, the repr() of string objects can include 8-bit characters
with the high bit set; I believe this is due to the recent
PRINT_MULTIBYTE_STRING changes to stringobject.c. This in turn screws
up test_pyexpat and test_rotor, which depend on the repr() of 8-bit
strings with high bit characters.
The solution (for now) is to force the LC_CTYPE locale to "C" after
importing rlcompleter. This is the locale required by the test suite
anyway.
imported on systems other than Windows, and in particular is imported
by test___all__; the compile farm reported that all Linux tests failed
due to this; isn't anyone in PythonDevLand running CVS on Linux?!).
ths "should be" skipped depends on os.path.supports_unicode_filenames,
not really on the platform. Fiddled the expected-skip constructor
appropriately.
list(xrange(sys.maxint / 4))
test. Changed 4 to 2.
The belief is that this test intended to trigger a bit of code in
listobject.c's NRESIZE macro that's looking for arithmetic overflow. As
written, it doesn't achieve that, though, and leaves it up to the platform
realloc() as to whether it wants to allocate 2 gigabytes. Some platforms
say "sure!", although they don't appear to mean it, and disaster ensues.
Changing 4 to 2 (just barely) manages to trigger the arithmetic overflow
test instead, leaving the platform realloc() out of it.
I'll backport this to the 2.2 branch next.
sys.getwindowsversion() on Windows (new enahanced Tim-proof <wink>
version), and fix test_pep277.py in a few minor ways.
Including doc and NEWS entries.
