5ff3f73d94 try to call __bytes__ before __index__ (closes #16722) 2012-12-19 15:27:41 -06:00

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.

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.

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()

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()

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.

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).
