stratakis a10d426bab bpo-36292: Mark unreachable code as such in long bitwise ops (GH-12333) 2019-03-18 18:59:20 +01:00
Serhiy Storchaka 6a44f6eef3
bpo-36048: Use __index__() instead of __int__() for implicit conversion if available. (GH-11952) 
Deprecate using the __int__() method in implicit conversions of Python
numbers to C integers.

bpo-35713: Split _Py_InitializeCore into subfunctions (GH-11650) 
* Split _Py_InitializeCore_impl() into subfunctions: add multiple pycore_init_xxx() functions
* Preliminary sys.stderr is now set earlier to get an usable
  sys.stderr ealier.
* Move code into _Py_Initialize_ReconfigureCore() to be able to call
  it from _Py_InitializeCore().
* Split _PyExc_Init(): create a new _PyBuiltins_AddExceptions()
  function.
* Call _PyExc_Init() earlier in _Py_InitializeCore_impl()
  and new_interpreter() to get working exceptions earlier.
* _Py_ReadyTypes() now returns _PyInitError rather than calling
  Py_FatalError().
* Misc code cleanup

bpo-35064 prefix smelly symbols that appear with COUNT_ALLOCS with _Py_ (GH-10152) 
Configuring python with ./configure --with-pydebug CFLAGS="-D COUNT_ALLOCS -O0"
makes "make smelly" fail as some symbols were being exported without the "Py_" or
"_Py" prefixes.

bpo-33012: Fix invalid function casts for long_long. (GH-6652) 
long_long() was used with three function types:
PyCFunction, getter and unaryfunction.

Siddhesh Poyarekar 55edd0c185 bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. (GH-6030) 
METH_NOARGS functions need only a single argument but they are cast
into a PyCFunction, which takes two arguments.  This triggers an
invalid function cast warning in gcc8 due to the argument mismatch.
Fix this by adding a dummy unused argument.

PyLong_FromString(): fix Coverity CID 1424951 (#4738) 
Explicitly cast digits (Py_ssize_t) to double to fix the following
false-alarm warning from Coverity:

"fsize_z = digits * log_base_BASE[base] + 1;"

CID 1424951: Incorrect expression (UNINTENDED_INTEGER_DIVISION)
Dividing integer expressions "9223372036854775783UL" and "4UL", and
then converting the integer quotient to type "double". Any remainder,
or fractional part of the quotient, is ignored.

Serhiy Storchaka 918403cfc3 bpo-29816: Shift operation now has less opportunity to raise OverflowError. (#680) 
ValueError always is raised rather than OverflowError for negative counts.

Victor Stinner de4ae3d486 Backed out changeset b9c9691c72c5 
Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like
_PyObject_CallArg1() uses more stack memory than
PyObject_CallFunctionObjArgs().
 2016-12-04 22:59:09 +01:00
Victor Stinner 27580c1fb5 Replace PyObject_CallFunctionObjArgs() with fastcall 
* PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func)
* PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg)

PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires
extra work to "parse" C arguments to build a C array of PyObject*.

_PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate
memory on the C stack.

This change is part of the fastcall project. The change on listsort() is
related to the issue #23507.

Optimize bytes.__mod__(args) for integere formats: %d (%i, %u), %o, %x and %X.
_PyBytesWriter is now used to format directly the integer into the writer

R David Murray 861470c836 #16518: Bring error messages in harmony with docs ("bytes-like object") 
Some time ago we changed the docs to consistently use the term 'bytes-like
object' in all the contexts where bytes, bytearray, memoryview, etc are used.
This patch (by Ezio Melotti) completes that work by changing the error
messages that previously reported that certain types did "not support the
buffer interface" to instead say that a bytes-like object is required.  (The
glossary entry for bytes-like object references the discussion of the buffer
protocol in the docs.)

Tim Peters 9259c21a63 Issue #19171: speed some cases of 3-argument long pow(). 
Reduce the base by the modulus when the base is larger than
the modulus.  This can unboundedly speed the "startup costs"
of doing modular exponentiation, particularly in cases where
the base is much larger than the modulus.  Original patch
by Armin Rigo, inspired by https://github.com/pyca/ed25519.

Tim Peters 81a93159d7 Issue #19171: speed some cases of 3-argument long pow(). 
Reduce the base by the modulus when the base is larger than
the modulus.  This can unboundedly speed the "startup costs"
of doing modular exponentiation, particularly in cases where
the base is much larger than the modulus.  Original patch
by Armin Rigo, inspired by https://github.com/pyca/ed25519.

Mark Dickinson 02515f7a3a Minor consistency fixes for some longobject.c exception messages: 
- replace 'long int' / 'long' by 'int'
 - fix capitalization of "Python" in PyLong_AsUnsignedLong
 - "is too large" -> "too large", for consistency with other messages.

Victor Stinner 1c8f059019 Issue #18520: Add a new PyStructSequence_InitType2() function, same than 
PyStructSequence_InitType() except that it has a return value (0 on success,
-1 on error).

 * PyStructSequence_InitType2() now raises MemoryError on memory allocation failure
 * Fix also some calls to PyDict_SetItemString(): handle error
