Zachary Ware bca9694ac1 Issue #21442: Fix MSVC compiler warning introduced by issue21377. 2014-05-06 11:42:37 -05:00
Victor Stinner db067af12a Issue #21233: Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(),
PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) and bytearray(int) are now
using ``calloc()`` instead of ``malloc()`` for large objects which is faster
and use less memory (until the bytearray buffer is filled with data).

Antoine Pitrou 161d695fb0 Issue #21377: PyBytes_Concat() now tries to concatenate in-place when the first argument has a reference count of 1.

Kristján Valur Jónsson c5cc5011ac Make the various iterators' "setstate" sliently and consistently clip the
index.  This avoids the possibility of setting an iterator to an invalid
state.

Christian Heimes d3afe781b1 Silence expression result unused warnings with clang.
The PyObject_INIT() macros returns obj:

Victor Stinner fd9e44db37 Issue #16286: optimize PyUnicode_RichCompare() for identical strings (same
pointer) for any operator, not only Py_EQ and Py_NE.

Code of bytes_richcompare() and PyUnicode_RichCompare() is now closer.

Benjamin Peterson 5ff3f73d94 try to call __bytes__ before __index__ (closes #16722) 2012-12-19 15:27:41 -06:00
Gregory P. Smith 27cbcd6241 Fix the internals of our hash functions to used unsigned values during hash
computation as the overflow behavior of signed integers is undefined.

In practice we require compiling everything with -fwrapv which forces overflow
to be defined as twos compliment but this keeps the code cleaner for checkers
or in the case where someone has compiled it without -fwrapv or their
compiler's equivalent.

Found by Clang trunk's Undefined Behavior Sanitizer (UBSan).

Cleanup only - no functionality or hash values change.

Chris Jerdonek e7f2186f99 Issue #16495: remove extraneous NULL encoding check from bytes_decode().
The NULL encoding check in bytes_decode() was unnecessary because this case
is already taken care of by the call to _Py_normalize_encoding() inside
PyUnicode_Decode().

Larry Hastings ca28e99202 Issue #14889: PyBytes_FromObject(bytes) now just increfs and returns.
Previously, if you passed in a bytes object, it would create a whole
new object.

Victor Stinner d0880d57b0 Simplify and optimize formatlong()
* Remove _PyBytes_FormatLong(): inline it into formatlong()
 * the input type is always a long, so remove the code for bool
 * don't duplicate the string if the length does not change
 * Use PyUnicode_DATA() instead of _PyUnicode_AsString()

Victor Stinner 8f825060f1 Check newly created consistency using _PyUnicode_CheckConsistency(str, 1)
* In debug mode, fill the string data with invalid characters
 * Simplify also reference counting in PyCodec_BackslashReplaceErrors()
   and PyCodec_XMLCharRefReplaceError()

Georg Brandl 09a7c72cad Merge from 3.1: Issue #13703: add a way to randomize the hash values of basic types (str, bytes, datetime)
in order to make algorithmic complexity attacks on (e.g.) web apps much more complicated.

The environment variable PYTHONHASHSEED and the new command line flag -R control this
behavior.

Gregory P. Smith 63e6c3222f Consolidate the occurrances of the prime used as the multiplier when hashing
to a single #define instead of having several copies in several files.

This excludes the Modules/ tree (datetime and expat both have a copy
for their own purposes with no need for it to be the same).
