Victor Stinner 71dc3d878a Issue #25349, #26249: Fix memleak in formatfloat() 2016-04-26 12:35:13 +02:00
Victor Stinner e914d41312 Issue #26766: Fix _PyBytesWriter_Finish() 
Return a bytearray object when bytearray is requested and when the small buffer
is used.

Fix also test_bytes: bytearray%args must return a bytearray type.

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.

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.

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 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 (%)

R David Murray 861470c836 #16518: Bring error messages in harmony with docs ("bytes-like object") 
Some time ago we changed the docs to consistently use the term 'bytes-like
object' in all the contexts where bytes, bytearray, memoryview, etc are used.
This patch (by Ezio Melotti) completes that work by changing the error
messages that previously reported that certain types did "not support the
buffer interface" to instead say that a bytes-like object is required.  (The
glossary entry for bytes-like object references the discussion of the buffer
protocol in the docs.)

Benjamin Peterson 5ff3f73d94 try to call __bytes__ before __index__ (closes #16722) 2012-12-19 15:27:41 -06:00
Gregory P. Smith 27cbcd6241 Fix the internals of our hash functions to used unsigned values during hash 
computation as the overflow behavior of signed integers is undefined.

In practice we require compiling everything with -fwrapv which forces overflow
to be defined as twos compliment but this keeps the code cleaner for checkers
or in the case where someone has compiled it without -fwrapv or their
compiler's equivalent.

Found by Clang trunk's Undefined Behavior Sanitizer (UBSan).

Cleanup only - no functionality or hash values change.

Chris Jerdonek e7f2186f99 Issue #16495: remove extraneous NULL encoding check from bytes_decode().

PyUnicode_Decode().

Eric Smith 0923d1d8d7 The other half of Issue #1580: use short float repr where possible. 
Addresses the float -> string conversion, using David Gay's code which
was added in Mark Dickinson's checkin r71663.

Also addresses these, which are intertwined with the short repr
changes:

- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'
- Issue #5515: 'n' formatting with commas no longer works poorly
    with leading zeros.
- PEP 378 Format Specifier for Thousands Separator: implemented
    for floats.

Georg Brandl abc387747d Add bytes/bytearray.maketrans() to mirror str.maketrans(), and deprecate 
string.maketrans() which actually works on bytes.  (Also closes #5675.)

Eric Smith a3b1ac8dca Added ',' thousands grouping to int.__format__. See PEP 378. 
This is incomplete, but I want to get some version into the next alpha. I am still working on:
Documentation.
More tests.
Implement for floats.

In addition, there's an existing bug with 'n' formatting that carries forward to thousands grouping (issue 5515).

Mark Dickinson e94c679df0 Issue #1717: rename tp_compare to tp_reserved. I'll change the
