Victor Stinner	f2eafa323b	Split PyBytes_FromObject() into subfunctions	10 years ago
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	10 years ago
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.	10 years ago
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	10 years ago
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.	10 years ago
Victor Stinner	661aaccf9d	Add use_bytearray attribute to _PyBytesWriter Issue #25399: Add a new use_bytearray attribute to _PyBytesWriter to use a bytearray buffer, instead of using a bytes object.	10 years ago
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	10 years ago

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".	10 years ago

Victor Stinner	be75b8cf23	Issue #25349 : Optimize bytes % int Optimize bytes.__mod__(args) for integere formats: %d (%i, %u), %o, %x and %X. _PyBytesWriter is now used to format directly the integer into the writer buffer, instead of using a temporary bytes object. Formatting is between 30% and 50% faster on a microbenchmark.	10 years ago

Victor Stinner	53926a1ce2	_PyBytesWriter: rename size attribute to min_size	10 years ago
Victor Stinner	fa7762ec06	Issue #25349 : Optimize bytes % args using the new private _PyBytesWriter API * Thanks to the _PyBytesWriter API, output smaller than 512 bytes are allocated on the stack and so avoid calling _PyBytes_Resize(). Because of that, change the default buffer size to fmtcnt instead of fmtcnt+100. * Rely on _PyBytesWriter algorithm to overallocate the buffer instead of using a custom code. For example, _PyBytesWriter uses a different overallocation factor (25% or 50%) depending on the platform to get best performances. * Disable overallocation for the last write. * Replace C loops to fill characters with memset() * Add also many comments to _PyBytes_Format() * Remove unused FORMATBUFLEN constant * Avoid the creation of a temporary bytes object when formatting a floating point number (when no custom formatting option is used) * Fix also reference leaks on error handling * Use Py_MEMCPY() to copy bytes between two formatters (%)	10 years ago
