Martin Panter 7462b64911 Issue #25523: Correct "a" article to "an" article
This changes the main documentation, doc strings, source code comments, and a
couple error messages in the test suite. In some cases the word was removed
or edited some other way to fix the grammar.

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 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

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.

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.

Victor Stinner f7d2471260 Merge 3.5 (sys.setrecursionlimit) 2015-10-13 00:16:07 +02:00
Victor Stinner 50856d5ae7 sys.setrecursionlimit() now raises RecursionError
Issue #25274: sys.setrecursionlimit() now raises a RecursionError if the new
recursion limit is too low depending at the current recursion depth. Modify
also the "lower-water mark" formula to make it monotonic. This mark is used to
decide when the overflowed flag of the thread state is reset.

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 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 b3653a3458 Issue #25318: cleanup code _PyBytesWriter
Rename "stack buffer" to "small buffer".

Add also an assertion in _PyBytesWriter_GetPos().

Victor Stinner 0016507c16 Issue #25318: Move _PyBytesWriter to bytesobject.c
Declare also the private API in bytesobject.h.

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.

Victor Stinner 6df29ada02 Issue #25150: Hide the private _Py_atomic_xxx symbols from the public
Python.h header to fix a compilation error with OpenMP. PyThreadState_GET()
becomes an alias to PyThreadState_Get() to avoid ABI incompatibilies.

It is important that the _PyThreadState_Current variable is always accessed
with the same implementation of pyatomic.h. Use the PyThreadState_Get()
function so extension modules will all reuse the same implementation.

Victor Stinner 9a8b177e60 Issue #25155: Add _PyTime_AsTimevalTime_t() function
On Windows, the tv_sec field of the timeval structure has the type C long,
whereas it has the type C time_t on all other platforms. A C long has a size of
32 bits (signed inter, 1 bit for the sign, 31 bits for the value) which is not
enough to store an Epoch timestamp after the year 2038.

Add the _PyTime_AsTimevalTime_t() function written for datetime.datetime.now():
convert a _PyTime_t timestamp to a (secs, us) tuple where secs type is time_t.
It allows to support dates after the year 2038 on Windows.

Enhance also _PyTime_AsTimeval_impl() to detect overflow on the number of
seconds when rounding the number of microseconds.

Victor Stinner 7667f58151 Issue #23517: fromtimestamp() and utcfromtimestamp() methods of
datetime.datetime now round microseconds to nearest with ties going to nearest
even integer (ROUND_HALF_EVEN), as round(float), instead of rounding towards
-Infinity (ROUND_FLOOR).

pytime API: replace _PyTime_ROUND_HALF_UP with _PyTime_ROUND_HALF_EVEN. Fix
also _PyTime_Divide() for negative numbers.

_PyTime_AsTimeval_impl() now reuses _PyTime_Divide() instead of reimplementing
rounding modes.
