Antoine Pitrou 5b4faae307 Issue #13992: The trashcan mechanism is now thread-safe. This eliminates 
sporadic crashes in multi-thread programs when several long deallocator
chains ran concurrently and involved subclasses of built-in container
types.

Note that the trashcan functions are part of the stable ABI, therefore
they have to be kept around for binary compatibility of extensions.

Antoine Pitrou 56cd62c04a Issue #13992: The trashcan mechanism is now thread-safe. This eliminates 
sporadic crashes in multi-thread programs when several long deallocator
chains ran concurrently and involved subclasses of built-in container
types.

Because of this change, a couple extension modules compiled for 3.2.4
(those which use the trashcan mechanism, despite it being undocumented)
will not be loadable by 3.2.3 and earlier. However, extension modules
compiled for 3.2.3 and earlier will be loadable by 3.2.4.

Victor Stinner d3f0882dfb Issue #14744: Use the new _PyUnicodeWriter internal API to speed up str%args and str.format(args) 
* Formatting string, int, float and complex use the _PyUnicodeWriter API. It
   avoids a temporary buffer in most cases.
 * Add _PyUnicodeWriter_WriteStr() to restore the PyAccu optimization: just
   keep a reference to the string if the output is only composed of one string
 * Disable overallocation when formatting the last argument of str%args and
   str.format(args)
 * Overallocation allocates at least 100 characters: add min_length attribute
   to the _PyUnicodeWriter structure
 * Add new private functions: _PyUnicode_FastCopyCharacters(),
   _PyUnicode_FastFill() and _PyUnicode_FromASCII()

The speed up is around 20% in average.

Victor Stinner b5c3ea3af3 Issue #14687: Optimize str%args 
* formatfloat() uses unicode_fromascii() instead of PyUnicode_DecodeASCII()
   to not have to check characters, we know that it is really ASCII
 * Use PyUnicode_FromOrdinal() instead of _PyUnicode_FromUCS4() to format
   a character: if avoids a call to ucs4lib_find_max_char() to compute
   the maximum character (whereas we already know it, it is just the character
   itself)

Benjamin Peterson 7b1668735a don't use a slot wrapper from a different special method (closes #14658) 
This also alters the fix to #11603. Specifically, setting __repr__ to
object.__str__ now raises a recursion RuntimeError when str() or repr() is
called instead of silently bypassing the recursion. I believe this behavior is
more correct.

  of the PEP can proceed in a test-driven manner.

Georg Brandl 2fb477c0f0 Merge 3.2: Issue #13703 plus some related test suite fixes. 2012-02-21 00:33:36 +01:00
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.
