Barry Warsaw b2e5794870 bpo-31338 (#3374) 
* Add Py_UNREACHABLE() as an alias to abort().
* Use Py_UNREACHABLE() instead of assert(0)
* Convert more unreachable code to use Py_UNREACHABLE()
* Document Py_UNREACHABLE() and a few other macros.

Eric Snow 2ebc5ce42a bpo-30860: Consolidate stateful runtime globals. (#3397) 
* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

Victor Stinner f17c3de263 Use _PyObject_CallNoArg() 
Replace:
    PyObject_CallFunctionObjArgs(callable, NULL)
with:
    _PyObject_CallNoArg(callable)
 2016-12-06 18:46:19 +01:00
Victor Stinner de4ae3d486 Backed out changeset b9c9691c72c5 
Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like
_PyObject_CallArg1() uses more stack memory than
PyObject_CallFunctionObjArgs().
 2016-12-04 22:59:09 +01:00
Victor Stinner 27580c1fb5 Replace PyObject_CallFunctionObjArgs() with fastcall 
* PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func)
* PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg)

PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires
extra work to "parse" C arguments to build a C array of PyObject*.

_PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate
memory on the C stack.

This change is part of the fastcall project. The change on listsort() is
related to the issue #23507.

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

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

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

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.
 2015-10-09 22:43:24 +02:00

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 (%)
