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.
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).
functions. Reworked {time,datetime}_new() to do what their corresponding
setstates used to do in their state-tuple-input paths, but directly,
without constructing an object with throwaway state first. Tightened
the "is this a state tuple input?" paths to check the presumed state
string-length too, and to raise an exception if the optional second state
element isn't a tzinfo instance (IOW, check these paths for type errors
as carefully as the normal paths).
anymore either, so don't. This also allows to get rid of obscure code
making __getnewargs__ identical to __getstate__ (hmm ... hope there
wasn't more to this than I realize!).
