| | |
* | | Add _PyBytesWriter_Resize() functionVictor Stinner2015-10-141-18/+30
| | | | | | | | | | | | This function gives a control to the buffer size without using min_size.

| | | | | | | | | | | | | | | | | | | | | * 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

| | | | | | | | | | | | enhance code to detect buffer under- and overflow.
* | | Optimize bytes.fromhex() and bytearray.fromhex()Victor Stinner2015-10-141-52/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* | | Optimize bytearray % argsVictor Stinner2015-10-141-18/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | | Add use_bytearray attribute to _PyBytesWriterVictor Stinner2015-10-141-28/+65
| | | | | | | | | | | | | | | Issue #25399: Add a new use_bytearray attribute to _PyBytesWriter to use a bytearray buffer, instead of using a bytes object.
* | | Rewrite PyBytes_FromFormatV() using _PyBytesWriter APIVictor Stinner2015-10-131-171/+165
| | | | | | | | | | | | | | | | | | | | | * 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
* | | Fix compilation error in _PyBytesWriter_WriteBytes() on WindowsVictor Stinner2015-10-121-1/+3
| | |
* | | Writer APIs: use empty string singletonsVictor Stinner2015-10-121-9/+14
| | | | | | | | | | | | | | | Modify _PyBytesWriter_Finish() and _PyUnicodeWriter_Finish() to return the empty bytes/Unicode string if the string is empty.
* | | Relax _PyBytesWriter APIVictor Stinner2015-10-121-8/+7
| | | | | | | | | | | | | | | | | | | | | Don't require _PyBytesWriter pointer to be a "char *". Same change for _PyBytesWriter_WriteBytes() parameter. For example, binascii uses "unsigned char*".
* | | Issue #25349: Add fast path for b'%c' % intVictor Stinner2015-10-091-10/+15
| | | | | | | | | | | | Optimize also %% formater.
* | | Issue #25349: Optimize bytes % intVictor Stinner2015-10-091-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | 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.
* | | Add _PyBytesWriter_WriteBytes() to factorize the codeVictor Stinner2015-10-091-0/+14

* | | _PyBytesWriter: simplify code to avoid "prealloc" parametersVictor Stinner2015-10-091-9/+7
| | | | | | | | | | | | | | | Substract preallocate bytes from min_size before calling _PyBytesWriter_Prepare().
* | | _PyBytesWriter: rename size attribute to min_sizeVictor Stinner2015-10-091-7/+7

* | | Issue #25349: Optimize bytes % args using the new private _PyBytesWriter APIVictor Stinner2015-10-091-59/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 (%)
* | | Issue #25318: cleanup code _PyBytesWriterVictor Stinner2015-10-091-17/+17
