89 it raises ValueError).
90
Jeffrey Yasskine75f59a2008-03-07 06:22:15 +000091- Issue #1193577: A .shutdown() method has been added to SocketServers

153=================================
Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +0000154
Barry Warsaw7c075232008-03-01 02:53:36 +0000155*Release date: 29-Feb-2008*
Neal Norwitz92422fb2006-08-18 03:57:54 +0000156
157Core and builtins
158-----------------
159
Fred Drakea8ee94b2008-03-01 02:45:07 +0000160- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +0000161 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +0000162
Georg Brandlad61bc82008-02-23 15:11:18 +0000163- Issue #2067: file.__exit__() now calls subclasses' close() method.
164
165- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +0000166
Facundo Batistafc2d0102008-02-23 12:01:13 +0000167- Issue #1881: An internal parser limit has been increased. Also see
168 issue 215555 for a discussion.
169
Eric Smitha73fbe72008-02-23 03:09:44 +0000170- Added the future_builtins module, which contains hex() and oct().
171 These are the PEP 3127 version of these functions, designed to be
172 compatible with the hex() and oct() builtins from Python 3.0. They
173 differ slightly in their output formats from the existing, unchanged
174 Python 2.6 builtins. The expected usage of the future_builtins
175 module is:
176 from future_builtins import hex, oct
177
Eric Smith7ef40bf2008-02-20 23:34:22 +0000178- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
179 exponents for exponents with absolute value < 100. Follows C99
180 standard. This is a change on Windows, which would use 3 digits.
181 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
182 so that any alterations it does to the resulting string will be
183 available in stringlib/formatter.h (for float.__format__).
184
Eric Smith5a3c1352008-02-19 13:21:56 +0000185- Implemented PEP 3101, Advanced String Formatting. This adds a new
186 builtin format(); a format() method for str and unicode; a
187 __format__() method to object, str, unicode, int, long, float, and
188 datetime; the class string.Formatter; and the C API
189 PyObject_Format().
190
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +0000191- Fixed several potential crashes, all caused by specially crafted __del__
192 methods exploiting objects in temporarily inconsistent state.
193
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +0000194- Issue #2115: Important speedup in setting __slot__ attributes. Also
195 prevent a possible crash: an Abstract Base Class would try to access a slot
196 on a registered virtual subclass.
197
Christian Heimes2f0da532008-02-15 06:57:08 +0000198- Fixed repr() and str() of complex numbers with infinity or nan as real or
199 imaginary part.
200
Andrew M. Kuchlingc6511a82008-03-04 01:48:26 +0000201- Clear all free lists during a gc.collect() of the highest generation in order
Christian Heimes3b718a72008-02-14 12:47:33 +0000202 to allow pymalloc to free more arenas. Python may give back memory to the
203 OS earlier.
204
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +0000205- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
206 collections.defaultdict, if its default_factory is set to a bound method.
207
Christian Heimesf75dbef2008-02-08 00:11:31 +0000208- Fixed a minor memory leak in dictobject.c. The content of the free
209 list was not freed on interpreter shutdown.
210
Christian Heimes6075a822008-02-06 12:44:34 +0000211- Limit free list of method and builtin function objects to 256 entries
212 each.
213
Amaury Forgeot d'Arc578a8ca2008-02-04 20:53:14 +0000214- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
215 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +0000216 to compact the internal free lists of pre-allocted ints and floats.
217
Christian Heimes951cc0f2008-01-31 23:08:23 +0000218- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
219 Python expected the return type int but the fork familie returns pi_t.
220
Mark Dickinson105be772008-01-31 22:17:37 +0000221- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
222 in the same code unit.
223
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +0000224- Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
225 the collections.Sequence API.
226
Christian Heimes4d4f2702008-01-30 11:32:37 +0000227- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
228 detection
229
Christian Heimes422051a2008-02-04 18:00:12 +0000230- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
Christian Heimes908caac2008-01-27 23:34:59 +0000231 internal lookup cache for ref leak tests.
232
Georg Brandl0cdf9a32008-01-26 14:14:20 +0000233- Patch #1473257: generator objects gain a gi_code attribute. This is the
234 same object as the func_code attribute of the function that produced the
235 generator.
236
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000237- Issue #1920: "while 0" statements were completely removed by the compiler,
238 even in the presence of an "else" clause, which is supposed to be run when
239 the condition is false. Now the compiler correctly emits bytecode for the
240 "else" suite.
241
Guido van Rossumeead05f2008-01-24 18:21:02 +0000242- A few crashers fixed: weakref_in_del.py (issue #1377858);
243 loosing_dict_ref.py (issue #1303614, test67.py);
244 borrowed_ref_[34].py (not in tracker).
245
Vinay Sajipd7cf32e2008-01-24 12:43:33 +0000246- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +0000247 suppressed while an extension is loaded by calling SetErrorMode in
248 dynload_win.c. The error is still reported properly.
249
Christian Heimes082c9b02008-01-23 14:20:50 +0000250- Bug #1915: Python compiles with --enable-unicode=no again. However
251 several extension methods and modules do not work without unicode
252 support.
253
Georg Brandl26543b12008-01-21 18:36:51 +0000254- Issue #1882: when compiling code from a string, encoding cookies in the
255 second line of code were not always recognized correctly.
256
Georg Brandl14404b62008-01-19 19:27:05 +0000257- Issue #1679: "0x" was taken as a valid integer literal.
258
Georg Brandl6caad7d2008-01-26 14:19:22 +0000259- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +0000260 added.
261
Christian Heimesc94e2b52008-01-14 04:13:37 +0000262- sys.float_info / PyFloat_GetInfo: The floating point information
263 object was converted from a dict to a specialized structseq object.
264
Christian Heimesf31b69f2008-01-14 03:42:48 +0000265- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000266 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +0000267
Georg Brandl6caad7d2008-01-26 14:19:22 +0000268- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +0000269 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +0000270
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +0000271- Patch #1700288: added a type attribute cache that caches method accesses,
272 resulting in speedups in heavily object-oriented code.
273
Neal Norwitz3fc15b82008-01-10 05:42:58 +0000274- Bug #1776: __import__() no longer accepts filenames on any platform.
275 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +0000276
Georg Brandlaed6c662008-01-07 17:25:53 +0000277- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
278
Georg Brandl2da0fce2008-01-07 17:09:35 +0000279- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
280 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
281 to attempt to write compiled bytecode files.
282
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000283- Improve some exception messages when Windows fails to load an extension
284 module. Now we get for example '%1 is not a valid Win32 application' instead

Raymond Hettingerfd7ed402007-12-18 21:24:09 +0000296- Compiler now generates simpler and faster code for dictionary literals.
297 The oparg for BUILD_MAP now indicates an estimated dictionary size.
298 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
299
Christian Heimesdb3d6cb2007-12-16 21:39:43 +0000300- Issue #1638: %zd configure test fails on Linux
301
Christian Heimes90e10e72007-12-14 02:35:23 +0000302- Issue #1620: New property decorator syntax was modifying the decorator
303 in place instead of creating a new decorator object.
304
Skip Montanaro26015492007-12-08 15:33:24 +0000305- Issue #1538: Avoid copying string in split/rsplit if the split
306 char is not found.
307
Andrew M. Kuchling395fe442007-12-05 13:27:20 +0000308- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +0000309 SystemError.
310
Nick Coghlanef01d822007-12-03 12:55:17 +0000311- PEP 366: Allow explicit relative imports when executing modules
312 inside packages with the -m switch via a new module level
313 __package__ attribute.
314
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +0000315- Issue #1402: Fix a crash on exit, when another thread is still running, and
316 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
317 PyGILState_Release() functions.
318
Christian Heimes28104c52007-11-27 23:16:44 +0000319- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
320
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000321- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +0000322 attribute of an empty cell object.
323
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +0000324- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
325 It now correctly saves its state between chunks of data.
326
Nick Coghlan327a39b2007-11-18 11:56:28 +0000327- Patch #1739468: Directories and zipfiles containing a __main__.py file can
328 now be directly executed by passing their name to the interpreter. The
329 directory/zipfile is automatically inserted as the first entry in sys.path.
330
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000331- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
332 generator expression when at the same time the executed code is closing a
333 paused generator.
334
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000335- sets and frozensets now have an isdisjoint() method.
336
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000337- optimize the performance of builtin.sum().
338
Neal Norwitz44f326e2007-10-05 05:29:17 +0000339- Fix warnings found by the new version of the Coverity checker.
340
Raymond Hettinger8f669372007-10-03 21:18:11 +0000341- The enumerate() builtin function is no longer bounded to sequences smaller
342 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
343 shifts from ints to longs.
344
Brett Cannon0b14f242007-09-30 19:45:10 +0000345- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
346 having a self-referential tuple, which is possible from C code. Nor did
347 object's tp_str consider that a type's tp_str could do something that could
348 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
349 respectively, fixed the issues.
350
Brett Cannon01531592007-09-17 03:28:34 +0000351- Issue #1164: It was possible to trigger deadlock when using the 'print'
352 statement to write to a file since the GIL was not released as needed. Now
353 PyObject_Print() does the right thing along with various tp_print
354 implementations of the built-in types and those in the collections module.
355
Brett Cannon4c20bc42007-09-11 21:02:28 +0000356- Issue #1147: Exceptions were directly allowing string exceptions in their
357 throw() method even though string exceptions no longer allowed.
358
Brett Cannona0c05512007-09-10 21:38:27 +0000359- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
360 list by using the recursion counter.
361
Brett Cannon1e534b52007-09-07 04:18:30 +0000362- Issue #1202533: Fix infinite recursion calls triggered by calls to
363 PyObject_Call() never calling back out to Python code to trigger recursion
364 depth updates/checks. Required the creation of a static RuntimeError
365 instance in case normalizing an exception put the recursion check value past
366 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
367
Martin v. Löwisa5136192007-09-04 14:19:28 +0000368- Patch #1031213: Decode source line in SyntaxErrors back to its original source
369 encoding.

Georg Brandla5ea6892007-06-01 11:33:33 +0000380
Neal Norwitz0ac60192007-05-27 04:08:54 +0000381- Add new attribute names for function objects. All the func_* become
382 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
383
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000384- Add -3 option to the interpreter to warn about features that are
385 deprecated and will be changed/removed in Python 3.0.
386
Georg Brandl2134e752007-05-21 20:34:16 +0000387- Patch #1686487: you can now pass any mapping after '**' in function
388 calls.
389
Collin Winter62903052007-05-18 23:11:24 +0000390- except clauses may now be spelled either "except E, target:" or
391 "except E as target:". This is to provide forwards compatibility with
392 Python 3.0.
393
Brett Cannon229cee22007-05-05 01:34:02 +0000394- Deprecate BaseException.message as per PEP 352.
395
Armin Rigo9790a272007-05-02 19:23:31 +0000396- Bug #1303614: don't expose object's __dict__ when the dict is
397 inherited from a builtin base.
398
Vinay Sajip8549ce32007-05-06 17:53:37 +0000399- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000400 setting a plain string, ie don't expand to single letter identifiers.
401
Raymond Hettinger13936692007-04-11 18:40:58 +0000402- Request #1191699: Slices can now be pickled.
403
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000404- Request #1193128: str.translate() now allows a None argument for
405 translations that only remove characters without re-mapping the
406 remaining characters.
407
Georg Brandl5cb76c12007-03-21 09:00:39 +0000408- Patch #1682205: a TypeError while unpacking an iterable is no longer
409 masked by a generic one with the message "unpack non-sequence".
410
Neal Norwitzaa754b72007-03-21 06:39:48 +0000411- Remove unused file Python/fmod.c.
412
Guido van Rossum143b5642007-03-23 04:58:42 +0000413- Bug #1683368: The object.__init__() and object.__new__() methods are
414 now stricter in rejecting excess arguments. The only time when
415 either allows excess arguments is when it is not overridden and the
416 other one is. For backwards compatibility, when both are
417 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000418 warning later). Also, type.__init__() insists on the same signature
419 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000420
Georg Brandl2b869942007-03-17 16:08:45 +0000421- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
422 to complex using its __complex__() method before falling back to the
423 __float__() method. Therefore, the functions in the cmath module now
424 can operate on objects that define a __complex__() method.
425
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000426- Patch #1623563: allow __class__ assignment for classes with __slots__.
427 The old and the new class are still required to have the same slot names.
428
Collin Winter77c67bd2007-03-16 04:11:30 +0000429- Patch #1642547: Fix an error/crash when encountering syntax errors in
430 complex if statements.
431
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000432- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
433 is called with an object that is faking its type.
434
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000435- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
436 name.
437
Georg Brandl5240d742007-03-13 20:46:32 +0000438- Patch #1444529: the builtin compile() now accepts keyword arguments.
439
Georg Brandl7b9c5552007-03-12 14:30:05 +0000440- Bug #1678647: write a newline after printing an exception in any
441 case, even when converting the value to a string failed.
442
Georg Brandl871f1bc2007-03-12 13:17:36 +0000443- The dir() function has been extended to call the __dir__() method on
444 its argument, if it exists. If not, it will work like before. This allows
445 customizing the output of dir() in the presence of a __getattr__().
446
Collin Winter276887b2007-03-12 16:11:39 +0000447- Patch #922167: Python no longer segfaults when faced with infinitely
448 self-recursive reload() calls (as reported by bug #742342).
449
Žiga Seilnacht89032082007-03-11 15:54:54 +0000450- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
451
Collin Wintere38051d2007-03-09 20:33:07 +0000452- Patch #1491866: change the complex() constructor to allow parthensized
453 forms. This means complex(repr(x)) now works instead of raising a
454 ValueError.
455
Georg Brandlaa2321b2007-03-07 00:40:28 +0000456- Patch #703779: unset __file__ in __main__ after running a file. This
457 makes the filenames the warning module prints much more sensible when
458 a PYTHONSTARTUP file is used.
459
Georg Brandl49aafc92007-03-07 00:34:46 +0000460- Variant of patch #697613: don't exit the interpreter on a SystemExit
461 exception if the -i command line option or PYTHONINSPECT environment
462 variable is given, but break into the interactive interpreter just like
463 on other exceptions or normal program exit.
464
Georg Brandl00cd8182007-03-06 18:41:12 +0000465- Patch #1638879: don't accept strings with embedded NUL bytes in long().
466
Georg Brandl098cd692007-03-06 12:17:50 +0000467- Bug #1674503: close the file opened by execfile() in an error condition.
468
Georg Brandl0fca97a2007-03-05 22:28:08 +0000469- Patch #1674228: when assigning a slice (old-style), check for the
470 sq_ass_slice instead of the sq_slice slot.
471
Neal Norwitz88516a62007-02-26 22:41:45 +0000472- When printing an unraisable error, don't print exceptions. before the name.
473 This duplicates the behavior whening normally printing exceptions.
474
Martin v. Löwisfd963262007-02-09 12:19:32 +0000475- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
476
Brett Cannon129bd522007-01-30 21:34:36 +0000477- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
478 catch a string exception raises DeprecationWarning.
479
Brett Cannonf5bee302007-01-23 23:21:22 +0000480- Bug #1377858: Fix the segfaulting of the interpreter when an object created
481 a weakref on itself during a __del__ call for new-style classes (classic
482 classes still have the bug).
483
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000484- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
485 frame's thread state.
486

488
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000489- Prevent seg fault on shutdown which could occur if an object
490 raised a warning.
491
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000492- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
493 to avoid relying on atexit.
494
Raymond Hettinger94547f72006-12-20 06:42:06 +0000495- Bug #1590891: random.randrange don't return correct value for big number

505
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000506- Bug #1576657: when setting a KeyError for a tuple key, make sure that
507 the tuple isn't used as the "exception arguments tuple".
508
Neal Norwitz21997af2006-10-28 21:19:07 +0000509- Bug #1565514, SystemError not raised on too many nested blocks.

515 if the assigned value for structmember fields gets truncated.
516
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000517- Update the peephole optimizer to remove more dead code (jumps after returns)
518 and inline unconditional jumps to returns.
519
Georg Brandl2c1375c2006-10-12 11:27:59 +0000520- Bug #1545497: when given an explicit base, int() did ignore NULs
521 embedded in the string to convert.
522
Georg Brandl846f73a2006-10-08 07:11:54 +0000523- Bug #1569998: break inside a try statement (outside a loop) is now
524 recognized and rejected.
525
Armin Rigo7ccbca92006-10-04 12:17:45 +0000526- list.pop(x) accepts any object x following the __index__ protocol.
527
Armin Rigo7ccbca92006-10-04 12:17:45 +0000528- A number of places, including integer negation and absolute value,
529 were fixed to not rely on undefined behaviour of the C compiler
530 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000531
Georg Brandl3267d282006-09-30 09:03:42 +0000532- Bug #1566800: make sure that EnvironmentError can be called with any
533 number of arguments, as was the case in Python 2.4.
534
Georg Brandl5d59c092006-09-30 08:43:30 +0000535- Patch #1567691: super() and new.instancemethod() now don't accept
536 keyword arguments any more (previously they accepted them, but didn't
537 use them).

548
Brett Cannon9adeab72006-09-20 18:34:28 +0000549- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
550 allows calling unicode() on exceptions classes directly to succeed.
551
Georg Brandl4e933132006-09-06 20:05:58 +0000552- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

557 imports (if not in package and if beyond toplevel package).
558
Tim Petersc10c9d02006-09-05 02:18:09 +0000559- Overflow checking code in integer division ran afoul of new gcc
560 optimizations. Changed to be more standard-conforming.

565
Neal Norwitzd34e4272006-09-05 02:36:20 +0000566- The return tuple from str.rpartition(sep) is (tail, sep, head) where
567 head is the original string if sep was not found.
568
Neal Norwitzdac090d2006-09-05 03:53:08 +0000569- Bug #1520864: unpacking singleton tuples in list comprehensions and
570 generator expressions (x for x, in ... ) works again. Fixing this problem
571 required changing the .pyc magic number. This means that .pyc files
572 generated before 2.5c2 will be regenerated.
573
Georg Brandl6caad7d2008-01-26 14:19:22 +0000574- ``with`` and ``as`` are now keywords.

1002
Georg Brandld9bef352007-03-13 19:32:21 +00001003- Patch #1533909: the timeit module now accepts callables in addition to

1057 returned string up to the first NUL character.

1070 and TestSuite subclasses (not instances) are no longer accepted in

1442 time so that opening a database previously created with the DB_DUP or

1447 DB[k] = v.

1709
Guido van Rossum7c862f82007-12-13 20:50:10 +00001710- Bug #1608: use -fwrapv when GCC supports it. This is important,
1711 newer GCC versions may optimize away overflow buffer overflow checks
1712 without this option!
1713
Martin v. Löwis63bf1492007-11-12 05:14:05 +00001714- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
1715
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00001716- Add a FAST_LOOPS build option that speeds-up looping by trading away
1717 periodic threadstate and signal checking in tight loops. By default,
1718 this option is turned-off. It should only be enabled in debugged,
1719 performance critical applications.
1720
Martin v. Löwisd44a4e92007-09-05 11:47:34 +00001721- Patch #786737: Allow building in a tree of symlinks pointing to

1729
Brett Cannon19fab762007-06-02 03:02:29 +00001730- Stop supporting AtheOS and cause a build error in configure for the platform.
1731
Georg Brandldb846032007-03-31 18:56:11 +00001732- Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS
1733 returned by python-config if Python was built with --enable-shared
1734 because that prevented the shared library from being used.
1735
Georg Brandl18c47f62007-03-13 10:19:22 +00001736- Patch #1569798: fix a bug in distutils when building Python from a
1737 directory within sys.exec_prefix.
1738
Martin v. Löwiseb623572007-03-12 10:50:39 +00001739- Bug #1675511: Use -Kpic instead of -xcode=pic32 on Solaris/x86.

1742
Martin v. Löwisaac13162006-10-19 10:58:46 +00001743- configure now checks whether gcc supports the PyArg_ParseTuple format
1744 attribute.
1745
Vinay Sajip76fdb8c2006-12-14 08:53:55 +00001746- Bug #1578513: Cross compilation was broken by a change to configure.
Martin v. Löwisfefbc202006-10-17 18:59:23 +00001747 Repair so that it's back to how it was in 2.4.3.
1748
Martin v. Löwisc9e82f62006-10-15 07:54:40 +00001749- Patch #1576954: Update VC6 build directory; remove redundant
1750 files in VC7.

Neal Norwitz92422fb2006-08-18 03:57:54 +00001766C API
1767-----
1768
Christian Heimes5b970ad2008-02-06 13:33:44 +00001769- Unified naming convention for free lists and their limits. All free lists
1770 in Object/ are named ``free_list``, the counter ``numfree`` and the upper
1771 limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
1772
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00001773- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
1774 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
1775 it does not steal a reference to the added item.
1776
1777- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
1778
Georg Brandl6caad7d2008-01-26 14:19:22 +00001779- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format and
1780 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t
1781 public functions.
1782
1783- Patch #1720595: add T_BOOL to the range of structmember types.
1784
1785- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
1786 ``PyFloat_GetInfo()`` to the float API.
1787
1788- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
1789 format code incorrectly truncated the length to an int, even when
1790 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
1791 results with huge strings.
1792
1793- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
1794 and Py_REFCNT.
1795
1796- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
1797 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
1798 PyVarObject_HEAD_INIT.
1799
1800- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
1801
1802- Patch #1733960: Allow T_LONGLONG to accept ints.
1803
1804- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
1805
Christian Heimes000a0742008-01-03 22:16:32 +00001806- Added a new API function ``PyImport_ImportModuleNoBlock``.
1807
Georg Brandl6caad7d2008-01-26 14:19:22 +00001808- Bug #1637022: Prefix AST symbols with _Py_.
1809
1810- Fix some leftovers from the conversion from int to Py_ssize_t
1811 (relevant to strings and sequences of more than 2**31 items).
1812
1813- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1814 outside of pystate.c and should not be necessary.
1815
Christian Heimes000a0742008-01-03 22:16:32 +00001816- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
1817 imports. In earlier versions they might have used relative imports under
1818 some conditions.
1819
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00001820- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00001821 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
1822
Neal Norwitz8a267062006-08-19 04:25:29 +00001823- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
1824 so it can be used as an expression.

1828-------
1829
Christian Heimes95d64472008-02-09 19:55:22 +00001830- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
1831 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
1832 Win2k for x86/32bit builds and WinXP for AMD64 builds.
1833
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00001834- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE
1835 and _CRT_NONSTDC_NO_DEPRECATE.
1836

Brett Cannon791d56f2007-05-31 19:40:42 +00001845- buildtools now raises a DeprecationWarning.
1846
Brett Cannon5e263512007-05-20 23:17:38 +00001847- Removed the macfs module. It had been deprecated since Python 2.5. This
1848 lead to the deprecation of macostools.touched() as it relied solely on macfs
1849 and was a no-op under OS X.
