Mark Dickinson23f0d6b2010-06-05 11:52:24 +000015- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +000016 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
17 arises from the "Overriding __eq__ blocks inheritance ..." warning
18 when turned into an exception: in this case the exception simply
19 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +000020
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +000021- Issue #8748: Fix two issues with comparisons between complex and integer
22 objects. (1) The comparison could incorrectly return True in some cases
23 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
24 (2) The comparison raised an OverflowError for large integers, leading
25 to unpredictable exceptions when combining integers and complex objects
26 in sets or dicts.
27
Mark Dickinson81336372010-05-30 12:12:25 +000028- Issue #5211: Implicit coercion for the complex type is now completely
29 removed. (Coercion for arithmetic operations was already removed in 2.7
30 alpha 4, but coercion for rich comparisons was accidentally left in.)
31
Victor Stinnerc49dfcc2010-05-25 22:30:32 +000032- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
33 and error handler, instead of writing to the C stderr file in utf-8
34
Georg Brandlfee0f442010-05-22 21:26:21 +000035- Issue #7902: When using explicit relative import syntax, don't try implicit
36 relative import semantics.

46
Georg Brandlfee0f442010-05-22 21:26:21 +000047- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
48 of the interpreter to set sys.argv without also modifying sys.path. This
49 helps fix `CVE-2008-5983
Antoine Pitrou6a265602010-05-21 17:12:38 +000050 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

Antoine Pitroufc69af12010-04-24 20:04:58 +0000263- Issue #5103: SSL handshake would ignore the socket timeout and block
264 indefinitely if the other end didn't respond.
265
Georg Brandlfee0f442010-05-22 21:26:21 +0000266- The do_handshake() method of SSL objects now adjusts the blocking mode of the
267 SSL structure if necessary (as other methods already do).

Georg Brandlfee0f442010-05-22 21:26:21 +0000277- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
278 string "python" as the *ident*. openlog() arguments are all optional and
279 keywords.

Georg Brandlfee0f442010-05-22 21:26:21 +0000312 filename and date, conforming to the 'standards' they were originally designed
313 to follow. This improves compatibility with patch tools.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000359 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
360 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
361 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

382-----------------
383
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000384- Issue #7301: Add environment variable $PYTHONWARNINGS.
385
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000386- Issue #8329: Don't return the same lists from select.select when no fds are
387 changed.
388
Georg Brandlfee0f442010-05-22 21:26:21 +0000389- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000390 on 64-bit machines. The shift count for either left or right shift is
391 permitted to be up to sys.maxsize.
392
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000393- Ensure that tokenization of identifiers is not affected by locale.

398
Georg Brandlfee0f442010-05-22 21:26:21 +0000399- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
400 with a non-empty format string. This is an effort to future-proof user
401 code. If a derived class does not currently implement __format__ but later
402 adds its own __format__, it would most likely break user code that had
403 supplied a format string. This will be changed to a DeprecationWaring in
404 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000431- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000432 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

Georg Brandlfee0f442010-05-22 21:26:21 +0000437- Issue #8257: The Decimal construct now accepts a float instance directly,
438 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000439
440 >>> Decimal(1.1)

442
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000443- collections.Counter() now supports a subtract() method.
444
Georg Brandlfee0f442010-05-22 21:26:21 +0000445- The functools module now has a total_ordering() class decorator to simplify
446 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000447
Georg Brandlfee0f442010-05-22 21:26:21 +0000448- The functools module also adds cmp_to_key() as a tool to transition old-style

Mark Dickinson7c63eee2010-04-02 22:27:36 +0000453
Georg Brandlfee0f442010-05-22 21:26:21 +0000454- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
455 InvalidOperation instead of returning False. (Comparisons involving a quiet
456 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
457 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000458
Georg Brandlfee0f442010-05-22 21:26:21 +0000459- Issue #2531: Comparison operations between floats and Decimal instances now
460 return a result based on the numeric values of the operands; previously they
461 returned an arbitrary result based on the relative ordering of id(float) and
462 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000463
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000464- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000465 argument `-` which tells it to read files to compile from stdin. Each line is
466 read on demand and the named file is compiled immediately. (Original patch by
467 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000476- Comparisons using one of <, <=, >, >= between a complex instance and a
477 Fractions instance now raise TypeError instead of returning True/False. This
478 makes Fraction <=> complex comparisons consistent with int <=> complex, float
479 <=> complex, and complex <=> complex comparisons.

588 the set of integer codes for which it was used differed between native packing
589 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000887 file position when calling `truncate()`. It would previously change the file
888 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000889 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

894 class used to represent files stored inside an archive. The new
895 implementation is significantly faster and can be wrapped in a
896 ``io.BufferedReader`` object for more speedups. It also solves an issue
897 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

910 encoded string for them. This ensures that the upload and register commands
911 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000988- The ``__complex__()`` method is now looked up on the class of instances to
989 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000991- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
992 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
993
Mark Dickinson1b34d252010-01-01 17:27:30 +0000994- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000995 DeprecationWarning when passed a float argument where an integer was expected.
996 These functions and methods now raise TypeError instead. The majority of the
997 effects of this change are in the extension modules, but some core functions

Georg Brandlba83f822010-03-14 09:50:54 +00001182- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1183 decimal string that's guaranteed to round back to x under correct rounding
1184 (with round-half-to-even rounding mode). Previously it gave a string based on
1185 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1186 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1187 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001188
Georg Brandlba83f822010-03-14 09:50:54 +00001189- Issue #7117: On almost all platforms: float-to-string and string-to-float
1190 conversions within Python are now correctly rounded. Places these conversions
1191 occur include: str for floats and complex numbers; the float and complex
1192 constructors; old-style and new-style numeric formatting; serialization and
1193 deserialization of floats and complex numbers using marshal, pickle and json;
1194 parsing of float and imaginary literals in Python code; Decimal-to-float
1195 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001196
Georg Brandlba83f822010-03-14 09:50:54 +00001197 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1198 providing correctly-rounded strtod and dtoa C functions. This code is
1199 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1200 the C compiler. There may be a small number of platforms on which correct
1201 operation of this code cannot be guaranteed, so the code is not used: notably,
1202 this applies to platforms where the C double format is not IEEE 754 binary64,
1203 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1204 and Python's configure script is unable to determine how to change the FPU
1205 precision. On these platforms conversions use the platform strtod and dtoa,
1206 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001208- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1209 uses the correctly-rounded string <-> float conversions described above (when
1210 available), and so produces correctly rounded results that will display nicely
1211 under the float repr. There are two related small changes: (1) round now
1212 accepts any class with an ``__index__()`` method for its second argument (but
1213 no longer accepts floats for the second argument), and (2) an excessively
1214 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1215 raises an exception.

1364 but with at least one decimal point and with a default precision
1365 of 12. Previously, the behavior the same but with a default precision of 6.
1366 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00001508- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1509 existing .py counterpart, override the co_filename attributes of all code
1510 objects if the original filename is obsolete (which can happen if the file has

1565
Georg Brandlba83f822010-03-14 09:50:54 +00001566- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1567 file objects with closefd=False. The file descriptor is still kept open but
1568 the file object behaves like a closed file. The ``FileIO`` object also got a
1569 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001589- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001592- On windows, ``os.chdir()`` given unicode was not working if
1593 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1594 this code path is really executed because I cannot move to such directory on
1595 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001597- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1598 element is temporarily replaced with an equivalent frozenset. But the
1599 eventual KeyError would always report the empty ``frozenset()`` as the missing
1600 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001620- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1621 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1622 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1623 of using the replace error handler in PyUnicode_DecodeUTF8().
1624
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001625- Issue #3739: The unicode-internal encoder now reports the number of characters

1627
Georg Brandlba83f822010-03-14 09:50:54 +00001628- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1630 gives improved memory leak detection when running under Valgrind, while taking
1631 advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00001703 __main__.py file. This allows applications that run other Python scripts to

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002998- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2999 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3000 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3001 ``printf`` function, whereas PyString_FromFormat has an independent
3002 implementation and uses "%zd" on all platforms for size_t values.
3003 This makes a difference on win64, where ``printf`` needs "%Id" to display
3004 64bit values.

3010 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00003023- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003024 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3025 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3026 when given a tuple of classes as second argument, were looking up
3027 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3028 type object.

3124 _check_logger_class from multiprocessing.
3125
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003126- Issue #2975: When compiling several extension modules with Visual Studio 2008
3127 from the same python interpreter, some environment variables would grow
3128 without limit.
3129
Benjamin Peterson37346b22008-08-23 20:27:43 +00003130- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003167What's New in Python 2.6 beta 3?
3168================================
3169
Barry Warsaw07a4a382008-08-21 01:15:08 +00003170*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003171
3172Core and Builtins
3173-----------------
3174
Guido van Rossumf8402962008-08-20 15:01:50 +00003175- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3176 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3177 extensions do not automatically benefit from the class attribute
3178 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3179 to their tp_flags field if they care. This is a backwards
3180 compatibility feature; in 3.0, all types will use the cache by
3181 default.
3182
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003183- Keyword arguments can now follow starred arguments. (``f(a, *args,
3184 keyword=23)`` is now valid syntax.)
3185
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003186- ctypes function pointers that are COM methods have a boolean True
3187 value again.
3188
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003189- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3190 by denying s# to parse objects that have a releasebuffer procedure,
3191 and introducing s*.
3192
Georg Brandl1e13ea92008-08-11 09:07:59 +00003193- Issue #3537: Fix an assertion failure when an empty but presized dict
3194 object was stored in the freelist.
3195
Mark Dickinsonb6467572008-08-04 21:30:09 +00003196- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3197 ValueError consistently across platforms.
3198
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003199- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3200 (64bit Unix, for example), unichr() would truncate its argument and return
3201 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3202
Neal Norwitze7d8be82008-07-31 17:17:14 +00003203- Apply security patches from Apple.
3204
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003205- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3206 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3207
Antoine Pitrou92f82162008-07-25 22:22:08 +00003208- Issue #1819: function calls with several named parameters are now on
3209 average 35% faster (as measured by pybench).
3210
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003211- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3212 the python debugger steps into a class statement: the free variables (local
3213 variables defined in an outer scope) would be deleted from the outer scope.
3214
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003215- Issue #2620: Overflow checking when allocating or reallocating memory
3216 was not always being done properly in some python types and extension
3217 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3218 all been updated to perform better checks and places in the code that
3219 would previously leak memory on the error path when such an allocation
3220 failed have been fixed.
3221
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003222Library
3223-------
3224
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003225- Issue #3612: Added some missing basic types in ctypes.wintypes.
3226
Benjamin Petersone977ad42008-08-20 01:42:01 +00003227- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3228 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3229
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003230- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3231 version reported by these tools does not necessarily follow the python
3232 version numbering scheme, so the module is less strict when parsing it.
3233
Nick Coghlanf70385a2008-08-18 12:42:46 +00003234- Issue #2235: Added Py3k warnings for types which will become unhashable
3235 under the stricter __hash__ inheritance rules in 3.0. Several types
3236 which did not meet the rules for hash invariants and were already
3237 unhashable in 3.0 have now been explicitly flagged as unhashable in
3238 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3239 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3240
Brett Cannon88f801d2008-08-18 00:46:22 +00003241- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3242 imported into the module but exposed as part of the module's API.
3243

3249
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003250- Issue #3575: Incremental decoder's decode function now takes bytearray
3251 by using 's*' instead of 't#'.
3252
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003253- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003254 fails unicode conversion on 2nd parameter. (windows only)
3255
Facundo Batista94f243a2008-08-17 03:38:39 +00003256- Issue 2464. urllib2 now supports a malformation in the URL received
3257 in a redirect.
3258
Brett Cannonabe423e2008-08-16 21:47:07 +00003259- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003260 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003261
Facundo Batistaeb90b782008-08-16 14:44:07 +00003262- Issue #2776: fixed small issue when handling an URL with double slash
3263 after a 302 response in the case of not going through a proxy.
3264
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003265- Issue #2676: in the email package, content-type parsing was hanging on
3266 pathological input because of quadratic or exponential behaviour of a
3267 regular expression.
3268
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003269- Issue #3476: binary buffered reading through the new "io" library is now
3270 thread-safe.
3271
Brett Cannonbf3157b2008-08-14 05:00:03 +00003272- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3273 since mimetools itself is deprecated. Because modules are cached, all
3274 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3275
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003276- Issue #3134: shutil referenced undefined WindowsError symbol.
3277
Robert Schuppenies14646332008-08-10 11:01:53 +00003278- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3279 menu entries were not deleted.
3280
Brett Cannon83e81842008-08-09 23:30:55 +00003281- Copied the implementation of reduce() to _functools.reduce() to have a
3282 version that did not raise a DeprecationWarning under -3.
3283
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003284- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3285 a MemoryError rather than silently stop the iteration.
3286
Guido van Rossum59ce9012008-08-09 14:55:34 +00003287- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3288 to _sre.compile() will now be rejected. This should not affect anybody
3289 since the re.compile() function never generates invalid re-bytecode.
3290
Skip Montanaroa032bf42008-08-08 22:52:51 +00003291- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3292 upon first access it can be automatically initialized from the csv file if
3293 it wasn't initialized during instantiation.
3294
Brett Cannon3aa2a492008-08-06 22:28:09 +00003295- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3296 the reload() built-in has been removed.
3297
Brett Cannon7e30b672008-08-04 21:52:25 +00003298- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003299 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3307 raised an AttributeError.
3308
Benjamin Peterson01a24322008-07-28 23:35:27 +00003309- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003310 asking for a specific length. This problem only affected files opened
3311 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003312

3335
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003336- Issue #3394: zipfile.writestr sets external attributes when passed a
3337 file name rather than a ZipInfo instance, so files are extracted with
3338 mode 0600 rather than 000 under Unix.
3339
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003340- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3341 argument in python 2.5, this broke code that subclassed Popen to include its
3342 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3356 coverage of the lookup process for special methods. The disclaimers
3357 regarding lack of coverage of new-style classes have also been
3358 removed, since the coverage is now fairly reasonable.

3362================================
3363
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003364*Release date: 17-Jul-2008*

3367-----------------
3368
Georg Brandl3e483f62008-07-16 22:57:41 +00003369- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3370 its methods now allow for items objects that can be converted to
3371 an integer using operator.index().
3372
Mark Dickinson64b7e502008-07-16 09:40:03 +00003373- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3374 produced a ValueError instead of giving the correct float.
3375
Eric Smitha5fa5a22008-07-16 00:11:49 +00003376- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3377 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3378
Mark Dickinson7103aa42008-07-15 19:08:33 +00003379- Issue #3008: the float type has a new instance method 'float.hex'
3380 and a new class method 'float.fromhex' to convert floating-point
3381 numbers to and from hexadecimal strings, respectively.
3382
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003383- Issue #2235: __hash__ is once again inherited by default. To allow
3384 collections.Hashable to remain meaningful in the presence of the
3385 default hash implementation (object.__hash__), it is now possible
3386 to explicit block inheritance of hash by setting __hash__=None at
3387 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3388 level.
3389
Nick Coghlanb028f502008-07-13 14:52:36 +00003390- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3391 the parent module cannot be found while performing an absolute import.
3392 This means that an incorrectly defined __package__ attribute will
3393 now only prevent relative imports in that module rather than causing
3394 all imports from that module to fail.
3395
Nick Coghlan14ff9942008-07-08 14:21:42 +00003396- Issue #2517: Allow unicode messages in Exceptions again by correctly
3397 bypassing the instance dictionary when looking up __unicode__ on

3412 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

3456 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003457 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00003867 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003868
3869 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00003929- Issue #1631171: Re-implement the 'warnings' module in C (the
3930 original Python code has been kept as backup). This will allow for
3931 using the 'warning's machinery in such places as the parser where
3932 use of pure Python code is not possible. Both the ``showarning()``
3933 and ``formatwarning()`` gain an optional 'line' argument which is
3934 not called by default for backwards-compatibility reasons. Setting
3935 ``warnings.showwarning()`` to an implementation that lacks support
3936 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003999- Issue #2550: The approach used by client/server code for obtaining
4000 ports to listen on in network-oriented tests has been refined in an
4001 effort to facilitate running multiple instances of the entire
4002 regression test suite in parallel without issue.
4003 test_support.bind_port() has been fixed such that it will always
4004 return a unique port -- which wasn't always the case with the
4005 previous implementation, especially if socket options had been set
4006 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4007 new implementation of bind_port() will actually raise an exception
4008 if it is passed an AF_INET/SOCK_STREAM socket with either the
4009 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4010 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4011 the socket it's been passed. This currently only applies to
4012 Windows. This option prevents any other sockets from binding to the
4013 host/port we've bound to, thus removing the possibility of the
4014 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4015 when a second SOCK_STREAM socket binds and accepts to a host/port
4016 that's already been bound by another socket. The optional preferred
4017 port parameter to bind_port() has been removed. Under no
4018 circumstances should tests be hard coding ports!
4019
4020 test_support.find_unused_port() has also been introduced, which will
4021 pass a temporary socket object to bind_port() in order to obtain an
4022 unused port. The temporary socket object is then closed and
4023 deleted, and the port is returned. This method should only be used
4024 for obtaining an unused port in order to pass to an external program
4025 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4026 a parameter to a server-oriented class that doesn't give you direct
4027 access to the underlying socket used.
4028
4029 Finally, test_support.HOST has been introduced, which should be used
4030 for the host argument of any relevant socket calls (i.e. bind and
4031 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004032
4033 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004034 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004035 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4036 test_asynchat and test_socket_ssl.
4037
Georg Brandl3ee81df2008-05-17 18:14:43 +00004038 It is now possible for multiple instances of the regression test
4039 suite to run in parallel without issue.

4307
Fred Drakea8ee94b2008-03-01 02:45:07 +00004308- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004309 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004311- Issue #2067: file.__exit__() now calls subclasses' close() method.
4312
4313- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004314
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004315- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004316 issue 215555 for a discussion.
4317
Eric Smitha73fbe72008-02-23 03:09:44 +00004318- Added the future_builtins module, which contains hex() and oct().
4319 These are the PEP 3127 version of these functions, designed to be
4320 compatible with the hex() and oct() builtins from Python 3.0. They
4321 differ slightly in their output formats from the existing, unchanged
4322 Python 2.6 builtins. The expected usage of the future_builtins
4323 module is:
4324 from future_builtins import hex, oct
4325
Eric Smith7ef40bf2008-02-20 23:34:22 +00004326- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4327 exponents for exponents with absolute value < 100. Follows C99
4328 standard. This is a change on Windows, which would use 3 digits.
4329 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4330 so that any alterations it does to the resulting string will be
4331 available in stringlib/formatter.h (for float.__format__).
4332
Eric Smith5a3c1352008-02-19 13:21:56 +00004333- Implemented PEP 3101, Advanced String Formatting. This adds a new
4334 builtin format(); a format() method for str and unicode; a
4335 __format__() method to object, str, unicode, int, long, float, and
4336 datetime; the class string.Formatter; and the C API
4337 PyObject_Format().
4338
Georg Brandl3ee81df2008-05-17 18:14:43 +00004339- Fixed several potential crashes, all caused by specially crafted
4340 __del__ methods exploiting objects in temporarily inconsistent
4341 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004342
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004343- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004344 prevent a possible crash: an Abstract Base Class would try to access
4345 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004346
Georg Brandl3ee81df2008-05-17 18:14:43 +00004347- Fixed repr() and str() of complex numbers with infinity or nan as
4348 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004349
Georg Brandl3ee81df2008-05-17 18:14:43 +00004350- Clear all free lists during a gc.collect() of the highest generation
4351 in order to allow pymalloc to free more arenas. Python may give back
4352 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004353
Georg Brandl3ee81df2008-05-17 18:14:43 +00004354- Issue #2045: Fix an infinite recursion triggered when printing a
4355 subclass of collections.defaultdict, if its default_factory is set
4356 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004357
Christian Heimesf75dbef2008-02-08 00:11:31 +00004358- Fixed a minor memory leak in dictobject.c. The content of the free
4359 list was not freed on interpreter shutdown.
4360
Georg Brandl21e99f42010-03-07 15:23:59 +00004361- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004362 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004363
Georg Brandl3ee81df2008-05-17 18:14:43 +00004364- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4365 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004366 to compact the internal free lists of pre-allocted ints and floats.
4367
Georg Brandl3ee81df2008-05-17 18:14:43 +00004368- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4369 calls. Python expected the return type int but the fork familie
4370 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004371
Georg Brandl3ee81df2008-05-17 18:14:43 +00004372- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4373 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004374
Georg Brandl3ee81df2008-05-17 18:14:43 +00004375- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4376 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004381- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4382 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004383
Georg Brandl3ee81df2008-05-17 18:14:43 +00004384- Patch #1473257: generator objects gain a gi_code attribute. This is
4385 the same object as the func_code attribute of the function that
4386 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004387
Georg Brandl3ee81df2008-05-17 18:14:43 +00004388- Issue #1920: "while 0" statements were completely removed by the
4389 compiler, even in the presence of an "else" clause, which is
4390 supposed to be run when the condition is false. Now the compiler
4391 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004392
Guido van Rossumeead05f2008-01-24 18:21:02 +00004393- A few crashers fixed: weakref_in_del.py (issue #1377858);
4394 loosing_dict_ref.py (issue #1303614, test67.py);
4395 borrowed_ref_[34].py (not in tracker).
4396
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004397- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004398 suppressed while an extension is loaded by calling SetErrorMode in
4399 dynload_win.c. The error is still reported properly.
4400
Georg Brandl3ee81df2008-05-17 18:14:43 +00004401- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004402 several extension methods and modules do not work without unicode
4403 support.
4404
Georg Brandl26543b12008-01-21 18:36:51 +00004405- Issue #1882: when compiling code from a string, encoding cookies in the
4406 second line of code were not always recognized correctly.
4407
Georg Brandl14404b62008-01-19 19:27:05 +00004408- Issue #1679: "0x" was taken as a valid integer literal.
4409
Georg Brandl6caad7d2008-01-26 14:19:22 +00004410- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004411 added.
4412
Christian Heimesc94e2b52008-01-14 04:13:37 +00004413- sys.float_info / PyFloat_GetInfo: The floating point information
4414 object was converted from a dict to a specialized structseq object.
4415
Georg Brandl3ee81df2008-05-17 18:14:43 +00004416- Patch #1816: Added sys.flags structseq. It exposes the status of
4417 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004418
Georg Brandl3ee81df2008-05-17 18:14:43 +00004419- Objects/structseq.c: Implemented new structseq representation. The
4420 patch makes structseqs (e.g. the return value of os.stat) more
4421 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004422
Georg Brandl3ee81df2008-05-17 18:14:43 +00004423- Patch #1700288: added a type attribute cache that caches method

4432 envvar and sys.dont_write_bytecode attribute. All these can be set
4433 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004434
Georg Brandl3ee81df2008-05-17 18:14:43 +00004435- Improve some exception messages when Windows fails to load an
4436 extension module. Now we get for example '%1 is not a valid Win32
4437 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004438

Christian Heimes0a8143f2007-12-18 23:22:54 +00004444- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004445 and INF. float("nan"), float("inf") and float("-inf") now work on
4446 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004447
Georg Brandl3ee81df2008-05-17 18:14:43 +00004448- Compiler now generates simpler and faster code for dictionary
4449 literals. The oparg for BUILD_MAP now indicates an estimated
4450 dictionary size. There is a new opcode, STORE_MAP, for adding
4451 entries to the dictionary.

4481 file can now be directly executed by passing their name to the
4482 interpreter. The directory/zipfile is automatically inserted as the
4483 first entry in sys.path.

4494
Georg Brandl21e99f42010-03-07 15:23:59 +00004495- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004496 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4497 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004498
Georg Brandl3ee81df2008-05-17 18:14:43 +00004499- Issue #1686386: Tuple's tp_repr did not take into account the
4500 possibility of having a self-referential tuple, which is possible
4501 from C code. Nor did object's tp_str consider that a type's tp_str
4502 could do something that could lead to an inifinite recursion.
4503 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4504 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004505
Georg Brandl3ee81df2008-05-17 18:14:43 +00004506- Issue #1164: It was possible to trigger deadlock when using the
4507 'print' statement to write to a file since the GIL was not released
4508 as needed. Now PyObject_Print() does the right thing along with
4509 various tp_print implementations of the built-in types and those in
4510 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00004519- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004520 PyObject_Call() never calling back out to Python code to trigger
4521 recursion depth updates/checks. Required the creation of a static
4522 RuntimeError instance in case normalizing an exception put the
4523 recursion check value past its limit. Fixes crashers
4524 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004539- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004540 __*__ attributes. (Some already existed, e.g., __doc__ and
4541 __name__.)

4547 calls.
4548
Collin Winter62903052007-05-18 23:11:24 +00004549- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004550 "except E as target:". This is to provide forwards compatibility
4551 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004558- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004559 setting a plain string, ie don't expand to single letter identifiers.
4560
Raymond Hettinger13936692007-04-11 18:40:58 +00004561- Request #1191699: Slices can now be pickled.
4562
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004563- Request #1193128: str.translate() now allows a None argument for
4564 translations that only remove characters without re-mapping the
4565 remaining characters.
4566
Georg Brandl5cb76c12007-03-21 09:00:39 +00004567- Patch #1682205: a TypeError while unpacking an iterable is no longer

4571
Guido van Rossum143b5642007-03-23 04:58:42 +00004572- Bug #1683368: The object.__init__() and object.__new__() methods are
4573 now stricter in rejecting excess arguments. The only time when
4574 either allows excess arguments is when it is not overridden and the
4575 other one is. For backwards compatibility, when both are
4576 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004577 warning later). Also, type.__init__() insists on the same signature
4578 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004579
Georg Brandl3ee81df2008-05-17 18:14:43 +00004580- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4581 object to complex using its __complex__() method before falling back
4582 to the __float__() method. Therefore, the functions in the cmath
4583 module now can operate on objects that define a __complex__()
4584 method.

4595 its type.

4601
Georg Brandl7b9c5552007-03-12 14:30:05 +00004602- Bug #1678647: write a newline after printing an exception in any
4603 case, even when converting the value to a string failed.
4604
Georg Brandl871f1bc2007-03-12 13:17:36 +00004605- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004606 its argument, if it exists. If not, it will work like before. This
4607 allows customizing the output of dir() in the presence of a
4608 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004616- Patch #1491866: change the complex() constructor to allow
4617 parthensized forms. This means complex(repr(x)) now works instead of
4618 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004619
Georg Brandlaa2321b2007-03-07 00:40:28 +00004620- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004621 makes the filenames the warning module prints much more sensible
4622 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004635- Patch #1674228: when assigning a slice (old-style), check for the
4636 sq_ass_slice instead of the sq_slice slot.
4637
Georg Brandl3ee81df2008-05-17 18:14:43 +00004638- When printing an unraisable error, don't print exceptions. before
4639 the name. This duplicates the behavior whening normally printing
4640 exceptions.

5206
Georg Brandl92a6bae2007-03-13 17:43:32 +00005207- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005208 are set for invalid interpolation sequences that would lead to

5265 TestCase and TestSuite subclasses (not instances) are no longer
5266 accepted in TestSuite.addTest(). This should cause no
5267 incompatibility since it never made sense with ordinary subclasses
5268 -- the failure just occurred later, with a more cumbersome
5269 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005550- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5551 with RFC 3207 and forgets any knowledge obtained from the server not
5552 obtained from the TLS negotiation itself. Patch contributed by Bill
5553 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005554
Georg Brandl3ee81df2008-05-17 18:14:43 +00005555- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005556 that the SMTP.starttls() caller no longer needs to call ehlo()
5557 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005558 does not claim to support starttls. Adds the
5559 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005614- itertools.chain() now has an alternate constructor,

5640 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5641 silently miscode subclasses of those types. Now, it raises a
5642 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005643

Georg Brandl3ee81df2008-05-17 18:14:43 +00005658 time so that opening a database previously created with the DB_DUP
5659 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5660 opens. Specifically: dictionary assignment to a DB object will
5661 replace all values for a given key when the database allows
5662 duplicate values. DB users should use DB.put(k, v) when they want
5663 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005664

5668
Georg Brandl3ee81df2008-05-17 18:14:43 +00005669- Patch #1185447: binascii.b2a_qp() now correctly quotes binary
5670 characters with ASCII value less than 32. Also, it correctly quotes
5671 dots only if they occur on a single line, as opposed to the previous

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005942- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005943 periodic threadstate and signal checking in tight loops. By
5944 default, this option is turned-off. It should only be enabled in
5945 debugged, performance critical applications.

6001 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006002
Georg Brandl3ee81df2008-05-17 18:14:43 +00006003- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6004 to ``PyTuple_SetItem``, it can be used to populate a brand new
6005 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006006

6017
Georg Brandl3ee81df2008-05-17 18:14:43 +00006018- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6019 of w# format code incorrectly truncated the length to an int, even
6020 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6021 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006022
Georg Brandl3ee81df2008-05-17 18:14:43 +00006023- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6043
6044- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6045 outside of pystate.c and should not be necessary.
6046
Georg Brandl3ee81df2008-05-17 18:14:43 +00006047- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6048 absolute imports. In earlier versions they might have used relative
6049 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006050
Georg Brandl3ee81df2008-05-17 18:14:43 +00006051- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6052 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006053
Georg Brandl3ee81df2008-05-17 18:14:43 +00006054- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006079- Removed the macfs module. It had been deprecated since Python 2.5.
6080 This lead to the deprecation of macostools.touched() as it relied
