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.
 2015-10-14 13:56:47 +02:00
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
 2015-10-14 13:32:13 +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.
 2015-10-14 12:02:39 +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.
 2015-10-14 09:56:53 +02:00
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.
 2015-10-14 09:41:48 +02:00
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
 2015-10-14 00:21:35 +02:00
Victor Stinner e9aa5950bb Fix compilation error in _PyBytesWriter_WriteBytes() on Windows 2015-10-12 13:57:47 +02:00
Victor Stinner 6c2cdae9e6 Writer APIs: use empty string singletons 
Modify _PyBytesWriter_Finish() and _PyUnicodeWriter_Finish() to return the
empty bytes/Unicode string if the string is empty.
 2015-10-12 13:29:43 +02:00
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*".

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.

Victor Stinner ce179bf6ba Add _PyBytesWriter_WriteBytes() to factorize the code 2015-10-09 12:57:22 +02:00

Substract preallocate bytes from min_size before calling
_PyBytesWriter_Prepare().
