Martin Panter 9513ba3b8f Issue #24802: Merge null termination fixes from 3.5 2015-11-07 03:15:32 +00:00
Martin Panter 61d6e4ae9d Issue #24802: Merge null termination fixes from 3.4 into 3.5 2015-11-07 02:56:11 +00:00
Martin Panter eeb896c411 Issue #24802: Copy bytes-like objects to null-terminated buffers if necessary 
This avoids possible buffer overreads when int(), float(), compile(), exec()
and eval() are passed bytes-like objects. Similar code is removed from the
complex() constructor, where it was not reachable.

Patch by John Leitch, Serhiy Storchaka and Martin Panter.

Victor Stinner e20310fa19 Issue #25556: Add assertions to PyObject_GetItem() to ensure that an exception 
is raised when it returns NULL.

Simplify also ceval.c: rely on the fact that PyObject_GetItem() raised an
exception when it returns NULL.

Martin Panter 7462b64911 Issue #25523: Correct "a" article to "an" article 
This changes the main documentation, doc strings, source code comments, and a

or edited some other way to fix the grammar.

After:

  TypeError: '<' not supported between instances of 'int' and 'NoneType'

Victor Stinner c3d2bc19e4 Use _PyBytesWriter in _PyBytes_FromIterator() 2015-10-14 14:15:49 +02:00
Victor Stinner c5c3ba4bec Add _PyBytesWriter_Resize() function 
This function gives a control to the buffer size without using min_size.

Victor Stinner 3c50ce39bf Factorize _PyBytes_FromList() and _PyBytes_FromTuple() code using a C macro 2015-10-14 13:50:40 +02:00
Victor Stinner f2eafa323b Split PyBytes_FromObject() into subfunctions 2015-10-14 13:44:29 +02:00
Victor Stinner 2ec8063cc9 Modify _PyBytes_DecodeEscapeRecode() to use _PyBytesAPI 
* Don't overallocate by 400% when recode is needed: only overallocate on demand
  using _PyBytesWriter.
* Use _PyLong_DigitValue to convert hexadecimal digit to int
* Create _PyBytes_DecodeEscapeRecode() subfunction

Victor Stinner 1285e5c805 Fix compiler warnings (uninitialized variables), false alarms in fact 2015-10-14 12:10:20 +02:00
Victor Stinner f6358a7e4c _PyBytesWriter_Alloc(): only use 10 bytes of the small buffer in debug mode to 
enhance code to detect buffer under- and overflow.

Victor Stinner f091033b14 Issue #25401: Remove now unused hex_digit_to_int() function 2015-10-14 11:59:46 +02:00
Victor Stinner 2bf8993db9 Optimize bytes.fromhex() and bytearray.fromhex() 
Issue #25401: Optimize bytes.fromhex() and bytearray.fromhex(): they are now
between 2x and 3.5x faster. Changes:

* Use a fast-path working on a char* string for ASCII string
* Use a slow-path for non-ASCII string
* Replace slow hex_digit_to_int() function with a O(1) lookup in
  _PyLong_DigitValue precomputed table
* Use _PyBytesWriter API to handle the buffer
* Add unit tests to check the error position in error messages
 2015-10-14 11:25:33 +02:00
Victor Stinner 772b2b09f2 Optimize bytearray % args 
Issue #25399: Don't create temporary bytes objects: modify _PyBytes_Format() to
create work directly on bytearray objects.

* Rename _PyBytes_Format() to _PyBytes_FormatEx() just in case if something
  outside CPython uses it
* _PyBytes_FormatEx() now uses (char*, Py_ssize_t) for the input string, so
  bytearray_format() doesn't need tot create a temporary input bytes object
* Add use_bytearray parameter to _PyBytes_FormatEx() which is passed to
  _PyBytesWriter, to create a bytearray buffer instead of a bytes buffer

Most formatting operations are now between 2.5 and 5 times faster.

Victor Stinner 661aaccf9d Add use_bytearray attribute to _PyBytesWriter

Victor Stinner 03dab786b2 Rewrite PyBytes_FromFormatV() using _PyBytesWriter API 
* Add much more unit tests on PyBytes_FromFormatV()
* Remove the first loop to compute the length of the output string
* Use _PyBytesWriter to handle the bytes buffer, use overallocation
* Cleanup the code to make simpler and easier to review

Victor Stinner c29e29bed1 Relax _PyBytesWriter API 
Don't require _PyBytesWriter pointer to be a "char *". Same change for
_PyBytesWriter_WriteBytes() parameter.

For example, binascii uses "unsigned char*".
