* _PyBytesWriter: simplify code to avoid "prealloc" parametersVictor Stinner2015-10-093-47/+47
| | | | | 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
| | | | | | Rename "stack buffer" to "small buffer". Add also an assertion in _PyBytesWriter_GetPos().
* Issue #25318: Fix backslashreplace()Victor Stinner2015-10-091-1/+1
| | | | Fix code to estimate the needed space.
* Issue #25318: Avoid sprintf() in backslashreplace()Victor Stinner2015-10-091-7/+18
| | | | | | Rewrite backslashreplace() to be closer to PyCodec_BackslashReplaceErrors(). Add also unit tests for non-BMP characters.
* Issue #25318: Fix compilation errorVictor Stinner2015-10-091-1/+1

* Optimize backslashreplace error handlerVictor Stinner2015-10-082-51/+160
| | | | | | | | | | Issue #25318: Optimize backslashreplace and xmlcharrefreplace error handlers in UTF-8 encoder. Optimize also backslashreplace error handler for ASCII and Latin1 encoders. Use the new _PyBytesWriter API to optimize these error handlers for the encoders. It avoids to create an exception and call the slow implementation of the error handler.
* Issue #25318: Add _PyBytesWriter APIVictor Stinner2015-10-082-132/+268
| | | | | | | | | | | Add a new private API to optimize Unicode encoders. It uses a small buffer allocated on the stack and supports overallocation. Use _PyBytesWriter API for UCS1 (ASCII and Latin1) and UTF-8 encoders. Enable overallocation for the UTF-8 encoder with error handlers. unicode_encode_ucs1(): initialize collend to collstart+1 to not check the current character twice, we already know that it is not ASCII.
