Serhiy Storchaka 4aa867959f Issue #23783: Fixed memory leak in PyObject_ClearWeakRefs() in case of 
MemoryError.
 2015-03-30 09:52:29 +03:00
Serhiy Storchaka 2c7b5a9d0d Issue #23466: %c, %o, %x, and %X in bytes formatting now raise TypeError on 
non-integer input.
 2015-03-30 09:19:08 +03:00
Serhiy Storchaka 48070c1248 Issue #23803: Fixed str.partition() and str.rpartition() when a separator 
is wider then partitioned string.
 2015-03-29 19:21:02 +03:00
Victor Stinner 1912b39def _PyUnicodeWriter_WriteStr() now checks that the input string is consistent 
in debug mode to detect bugs earlier.

_PyUnicodeWriter_Finish() doesn't check if the read only string is consistent,
whereas it does check consistency for strings built by itself.
 2015-03-26 09:37:23 +01:00
Serhiy Storchaka d357b89f0b Issue #22079: Deprecation warning now is issued in PyType_Ready() instead of 
raising TypeError when statically allocated type subclasses dynamically
allocated type
 2015-03-22 09:46:36 +02:00
Victor Stinner dabbfe7b30 Issue #23573: Fix bytes.rfind() and bytearray.rfind() on Windows 
Windows has no memrchr() function.

This change is only a workaround, the optimization must be reenabled on other
platforms.
 2015-03-25 03:16:32 +01:00
Serhiy Storchaka d9d769fcdd Issue #23573: Increased performance of string search operations (str.find, 
str.index, str.count, the in operator, str.split, str.partition) with
arguments of different kinds (UCS1, UCS2, UCS4).
 2015-03-24 21:55:47 +02:00
Victor Stinner 944fbcc478 Issue #23571: Enhance _Py_CheckFunctionResult() 
Too bad, sometimes Py_FatalError() is unable to write the exception into
sys.stderr (on "AMD64 OpenIndiana 3.x" buildbot, the buildbot was probably out
of memory).

Call Py_FatalError() with a different message for the two cases (result+error,
or no result and no error).
 2015-03-24 16:28:52 +01:00
Victor Stinner 454bd3a277 stdprinter_write(): mention the encoding 2015-03-24 13:40:29 +01:00
Victor Stinner 3b06dfb9d1 Issue #23571: In debug mode, _Py_CheckFunctionResult() now calls 
Py_FatalError() instead of using an assertion in debug mode. Py_FatalError()
displays the current exception and the traceback which contain more information
than just the assertion error.
 2015-03-24 12:53:59 +01:00
Victor Stinner efde146b0c Issue #23571: _Py_CheckFunctionResult() now gives the name of the function 
which returned an invalid result (result+error or no result without error) in
the exception message.

Add also unit test to check that the exception contains the name of the
function.

Special case: the final _PyEval_EvalFrameEx() check doesn't mention the
function since it didn't execute a single function but a whole frame.

Serhiy Storchaka 1dd49824df Issue #23681: The -b option now affects comparisons of bytes with int. 2015-03-20 16:54:57 +02:00
Victor Stinner f50e187724 Fix compiler warnings: comparison between signed and unsigned numbers 2015-03-20 11:32:24 +01:00

Antoine Pitrou 31084ba528 Issue #23632: Memoryviews now allow tuple indexing (including for multi-dimensional memoryviews). 2015-03-19 23:29:36 +01:00
Victor Stinner 66aab0c4b5 Issue #23708: Add _Py_read() and _Py_write() functions to factorize code handle 
EINTR error and special cases for Windows.

These functions now truncate the length to PY_SSIZE_T_MAX to have a portable
and reliable behaviour. For example, read() result is undefined if counter is
greater than PY_SSIZE_T_MAX on Linux.

Antoine Pitrou a654510150 Issue #23629: Fix the default __sizeof__ implementation for variable-sized objects. 2015-03-10 22:32:00 +01:00
Victor Stinner 283f3f8ab3 Issue #23571: Oops, fix #ifdef assert() 
assert() are noop when NDEBUG is defined. We want the opposite.
 2015-03-09 15:55:37 +01:00
Victor Stinner 4a7cc88472 Issue #23571: PyObject_Call(), PyCFunction_Call() and call_function() now 
raise a SystemError if a function returns a result and raises an exception.
The SystemError is chained to the previous exception.

Refactor also PyObject_Call() and PyCFunction_Call() to make them more readable.

Remove some checks which became useless (duplicate checks).

Change reviewed by Serhiy Storchaka.

Raymond Hettinger bd9b200b87 Update copyright for 2015 updates. 2015-01-18 16:10:30 -08:00
Raymond Hettinger 9cd6a789c6 Clean-up, simplify, and slightly speed-up bounds logic in set_pop(). 
Elsewhere in the setobject.c code we do a bitwise-and with the mask
instead of using a conditional to reset to zero on wrap-around.
Using that same technique here use gives cleaner, faster, and more
consistent code.
