readability.
load_bool(): Now that I know the intended difference between _PUSH and
_APPEND, used the right one.
Pdata_grow(): Squashed out a redundant overflow test.
wasn't used outside the assert (and hence caused a compiler warning
about an unused variable in NDEBUG mode). The assert wasn't very
useful any more.
_PyLong_NumBits(): moved the calculation of ndigits after asserting
that v != NULL.
huge. On older Linux systems, the C library's strtod() apparently
gives up before seeing the end of the string when it sees so many
digits that it thinks the result must be Infinity. (It is wrong, BTW
-- there could be an "e-10000" hiding behind 10,000 digits.) The
shorter shuge still tests what it's testing, without relying on
strtod() doing a super job.
exception, ResourceDenied. This is used to distinguish between tests that
are skipped for other reasons (platform support, missing data, etc.) from
those that are skipped because a "resource" has not been enabled. This
prevents those tests from being reported as unexpected skips for the
platform; those should only be considered unexpected skips if the resource
were enabled.
[ 676342 ] after using pdb readline does not work correctly
using Michael Stone's patch so the completer functionality of
cmd is only setup between preloop and postloop.
description since while there, it is useless and ignored, according to Tim's
commen. (PyInt_FromString is also not described, but PyLong_FromString is.
Is the former deprecated?)
a function, then
p->f(arg1, arg2, ...)
is semantically the same as
(*p->f)(arg1, arg2, ...)
Changed all instances of the latter into the former. Given how often
the code embeds this kind of expression in an if test, the unnecessary
parens and dereferening operator were a real drag on readability.
loops. Renamed DATA and BINDATA to DATA0 and DATA1. Included
disassemblies, but noted why we can't test them. Added XXX comment to
cPickle about a mysterious comment, where pickle and cPickle diverge
in how they number PUT indices.
Assorted code cleanups; e.g., sizeof(char) is 1 by definition, so there's
no need to do things like multiply by sizeof(char) in hairy malloc
arguments. Fixed an undetected-overflow bug in readline_file().
longobject.c: Fixed a really stupid bug in the new _PyLong_NumBits.
pickle.py: Fixed stupid bug in save_long(): When proto is 2, it
wrote LONG1 or LONG4, but forgot to return then -- it went on to
append the proto 1 LONG opcode too.
Fixed equally stupid cancelling bugs in load_long1() and
load_long4(): they *returned* the unpickled long instead of pushing
it on the stack. The return values were ignored. Tests passed
before only because save_long() pickled the long twice.
Fixed bugs in encode_long().
Noted that decode_long() is quadratic-time despite our hopes,
because long(string, 16) is still quadratic-time in len(string).
It's hex() that's linear-time. I don't know a way to make decode_long()
linear-time in Python, short of maybe transforming the 256's-complement
bytes into marshal's funky internal format, and letting marshal decode
that. It would be more valuable to make long(string, 16) linear time.
pickletester.py: Added a global "protocols" vector so tests can try
all the protocols in a sane way. Changed test_ints() and test_unicode()
to do so. Added a new test_long(), but the tail end of it is disabled
because it "takes forever" under pickle.py (but runs very quickly under
cPickle: cPickle proto 2 for longs is linear-time).
