Victor Stinner 0cdad1e2bc Issue #25349: Add fast path for b'%c' % int 
Optimize also %% formater.
 2015-10-09 22:50:36 +02:00
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.

R David Murray aecf63ee3a Merge #25328: add missing raise keyword in decode_data+SMTPUTF8 check. 2015-10-09 10:20:58 -04:00
R David Murray 1a815389cc #25328: add missing raise keyword in decode_data+SMTPUTF8 check. 
This is a relatively benign bug, since having both be true was correctly
rejected at in SMTPServer even before this patch.

Patch by Xiang Zhang.

Victor Stinner 6bd525b656 Optimize error handlers of ASCII and Latin1 encoders when the replacement 
string is pure ASCII: use _PyBytesWriter_WriteBytes(), don't check individual
character.

Cleanup unicode_encode_ucs1():

* Rename repunicode to rep
* Clear rep object on error
* Factorize code between bytes and unicode path

Victor Stinner ad7715891e _PyBytesWriter: simplify code to avoid "prealloc" parameters 
Substract preallocate bytes from min_size before calling
_PyBytesWriter_Prepare().

Victor Stinner 53926a1ce2 _PyBytesWriter: rename size attribute to min_size 2015-10-09 12:37:03 +02:00
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 (%)

Victor Stinner e7bf86cd7d Optimize backslashreplace error handler 
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.

Victor Stinner fdfbf78114 Issue #25318: Add _PyBytesWriter API 
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.
