18 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
19 benefit compared to the dynamic memory allocation fallback. Patch by
20 Charles-François Natali.
21
Benjamin Peterson821a8ea2010-04-16 22:35:38 +000022- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

39 where the method could block indefinitely if called just before the
40 event loop started running. This also fixes the occasional freezes
41 witnessed in test_httpservers.
42
Antoine Pitroufc69af12010-04-24 20:04:58 +000043- Issue #5103: SSL handshake would ignore the socket timeout and block
44 indefinitely if the other end didn't respond.
45
Antoine Pitrou4d3e3722010-04-24 19:57:01 +000046- The do_handshake() method of SSL objects now adjusts the blocking mode of
47 the SSL structure if necessary (as other methods already do).
48
Georg Brandl4341e542010-04-24 09:08:10 +000049- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
50
Antoine Pitroub558f172010-04-23 23:25:45 +000051- Issue #5238: Calling makefile() on an SSL object would prevent the

62 a non-infinite timeout. Also make that method friendlier with applications
63 wanting to continue using the socket in clear-text mode, by disabling
64 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
65
Antoine Pitrouc715a9e2010-04-21 19:28:03 +000066- Issue #8484: Load all ciphers and digest algorithms when initializing

89 Locke and Hans Ulrich Niedermann.
90
R. David Murray1a14d3d2010-04-12 16:35:19 +000091- Issue #7585: difflib context and unified diffs now place a tab between
92 filename and date, conforming to the 'standards' they were originally
93 designed to follow. This improves compatibility with patch tools.
94
R. David Murray27ef9372010-04-12 14:26:06 +000095- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

129-----------------
130
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000131- Issue #7301: Add environment variable $PYTHONWARNINGS.

Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000133- Issue #8329: Don't return the same lists from select.select when no fds are
134 changed.
135
Mark Dickinson82791672010-04-06 16:47:55 +0000136- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
137 on 64-bit machines. The shift count for either left or right shift is
138 permitted to be up to sys.maxsize.
139
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000140- Ensure that tokenization of identifiers is not affected by locale.

145
Eric Smithd44b2fc2010-04-02 12:30:56 +0000146- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
147 is called with a non-empty format string. This is an effort to
148 future-proof user code. If a derived class does not currently
149 implement __format__ but later adds its own __format__, it would
150 most likely break user code that had supplied a format string. This
151 will be changed to a DeprecationWaring in Python 3.3 and it will be
152 an error in Python 3.4.
153
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000154- Issue #8268: Old-style classes (not just instances) now support weak
155 references.

Victor Stinner6cbf90f2010-03-25 00:21:53 +0000157- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
158 optimizations are disabled when --with-pydebug is used.
159
Victor Stinnerc7790ed2010-03-22 12:36:28 +0000160- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +0000161

Georg Brandlba83f822010-03-14 09:50:54 +0000168 (SIGINT). If an error occurs while importing the site module, the error is
169 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000170 module.

178
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000179- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
180 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
181 and `ssl.OPENSSL_VERSION_NUMBER`.
182
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000183- Issue #8310: Allow dis to examine new style classes.
184
Mark Dickinson8a950712010-04-03 15:47:46 +0000185- Issue #8257: The Decimal construct now accepts a float instance
186 directly, converting that float to a Decimal of equal value:
187
188 >>> Decimal(1.1)
189 Decimal('1.100000000000000088817841970012523233890533447265625')

192
Raymond Hettingera551f312010-04-04 18:34:45 +0000193- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000194 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000195
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000196- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000197 old-style comparison functions to new-style key-functions.
198
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000199- Issue #8294: The Fraction constructor now accepts Decimal and float
200 instances directly.
201
Mark Dickinsone096e822010-04-02 10:17:07 +0000202- Issue #7279: Comparisons involving a Decimal signaling NaN now
203 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000204 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
205 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000206
Mark Dickinson99d80962010-04-02 08:53:22 +0000207- Issue #2531: Comparison operations between floats and Decimal
208 instances now return a result based on the numeric values of the

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000212- Issue #8233: When run as a script, py_compile.py optionally takes a single
213 argument `-` which tells it to read files to compile from stdin. Each line
214 is read on demand and the named file is compiled immediately. (Original
215 patch by Piotr Ożarowski).
216
217- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
218 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000219
Florent Xicluna58b65662010-03-30 16:29:03 +0000220- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
221 form feed (0x0C) are now considered linebreaks, as specified in Unicode
222 Standard Annex #14. See issue #7643.

224
Mark Dickinson9588d992010-03-27 11:14:37 +0000225- Comparisons using one of <, <=, >, >= between a complex instance and
226 a Fractions instance now raise TypeError instead of returning
227 True/False. This makes Fraction <=> complex comparisons consistent with
228 int <=> complex, float <=> complex, and complex <=> complex comparisons.
229
Michael Foorde6410c52010-03-29 20:04:23 +0000230- Addition of ``WeakSet`` to the ``weakref`` module.

241 now silenced.
242
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000243- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

250 method to LoggerAdapter.
251
Vinay Sajip31e928e2010-03-22 13:02:28 +0000252- Issue #8201: logging: Handle situation of non-ASCII and Unicode

260 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
261 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000262

Georg Brandlba83f822010-03-14 09:50:54 +0000284 for ``TimedRotatingFileHandler`` by using the modification time of an
285 existing log file to compute the next rollover time. If the log file does
286 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000287

295
Georg Brandlba83f822010-03-14 09:50:54 +0000296- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
297 a base64 transfer-encoded payload *after* decoding it; it no longer does.

326 integer format code, struct.pack first attempts to convert the non-integer
327 using its __index__ method. If that method is non-existent or raises
328 TypeError it goes on to try the __int__ method, as described below.
329
Georg Brandlba83f822010-03-14 09:50:54 +0000330- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
331 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
332 argument's __int__ method to convert to an integer before packing. It also
333 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
334 was inconsistent: __int__ was used for some integer codes but not for others,
335 and the set of integer codes for which it was used differed between native
336 packing and standard packing.)

561 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000562 library would return a bogus result; on Solaris, it was possible to crash the
563 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +0000576- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
577 and add the additional members returned in an OSVERSIONINFOEX structure. The
578 new members are service_pack_major, service_pack_minor, suite_mask, and
579 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000581- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
582 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
583 returning NULL. The macro now returns a statically allocated empty string
584 instead.

594 strings,
595 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
596 numeric strings corresponding to subnormal values,
597 (3) a memory leak for some values large enough to cause overflow, and
598 (4) a number of flaws that could lead to incorrectly rounded results.

616 XML processing instructions and comments. These raw characters are allowed
617 by the XML specification, and are necessary when outputting e.g. PHP code in
618 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +0000626- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000627 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000628 Also, raise ValueError rather than TypeError when an unknown TIPC address
629 type is specified. Patch by Brian Curtin.
630
Vinay Sajip28c382f2010-02-04 18:48:53 +0000631- logging: Implemented PEP 391.
632
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000633- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000634 file position when calling `truncate()`. It would previously change the file
635 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000636 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
637
Benjamin Petersone06f7112010-01-28 02:15:02 +0000638- UserDict is now a new-style class.
639
Georg Brandlba83f822010-03-14 09:50:54 +0000640- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
641 class used to represent files stored inside an archive. The new
642 implementation is significantly faster and can be wrapped in a
643 ``io.BufferedReader`` object for more speedups. It also solves an issue
644 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
645 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +0000646

Georg Brandlba83f822010-03-14 09:50:54 +0000652- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
653 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000654
Georg Brandlba83f822010-03-14 09:50:54 +0000655- Issue #7748: Since unicode values are supported for some metadata options in
656 Distutils, the DistributionMetadata get_* methods will now return an utf-8
657 encoded string for them. This ensures that the upload and register commands
658 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000659
Georg Brandlba83f822010-03-14 09:50:54 +0000660- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000661 headers in multipart/signed MIME parts, which fixes one of the sources of

732Core and Builtins
733-----------------
734
Georg Brandlba83f822010-03-14 09:50:54 +0000735- The ``__complex__()`` method is now looked up on the class of instances to
736 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000737
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000738- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
739 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
740
Mark Dickinson1b34d252010-01-01 17:27:30 +0000741- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000742 DeprecationWarning when passed a float argument where an integer was expected.
743 These functions and methods now raise TypeError instead. The majority of the
744 effects of this change are in the extension modules, but some core functions
745 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
746 and many unicode/str methods.

757 used to drop the time part of the result.
758
Georg Brandlba83f822010-03-14 09:50:54 +0000759- Issue #1811: Improve accuracy and cross-platform consistency for true division
760 of integers: the result of a/b is now correctly rounded for ints a and b (at
761 least on IEEE 754 platforms), and in particular does not depend on the
762 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000763
Georg Brandlba83f822010-03-14 09:50:54 +0000764- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +0000769 executables on OSX.
770
Georg Brandlba83f822010-03-14 09:50:54 +0000771 These executables now work properly with the arch(1) command: ``arch -ppc
772 python`` will start a universal binary version of python in PPC mode (unlike
773 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000774

Georg Brandlba83f822010-03-14 09:50:54 +0000911- Issue #3382: 'F' formatting for float and complex now convert the result to
912 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
913 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000914
Georg Brandlba83f822010-03-14 09:50:54 +0000915- Remove switch from "%f" formatting to "%g" formatting for floats larger than
916 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000917
Georg Brandlba83f822010-03-14 09:50:54 +0000918- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

927 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000928
Georg Brandlba83f822010-03-14 09:50:54 +0000929- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
930 decimal string that's guaranteed to round back to x under correct rounding
931 (with round-half-to-even rounding mode). Previously it gave a string based on
932 rounding x to 17 decimal digits. repr(x) for a complex number behaves
933 similarly. On platforms where the correctly-rounded strtod and dtoa code is
934 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000935
Georg Brandlba83f822010-03-14 09:50:54 +0000936- Issue #7117: On almost all platforms: float-to-string and string-to-float
937 conversions within Python are now correctly rounded. Places these conversions
938 occur include: str for floats and complex numbers; the float and complex
939 constructors; old-style and new-style numeric formatting; serialization and
940 deserialization of floats and complex numbers using marshal, pickle and json;
941 parsing of float and imaginary literals in Python code; Decimal-to-float
942 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000943
Georg Brandlba83f822010-03-14 09:50:54 +0000944 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
945 providing correctly-rounded strtod and dtoa C functions. This code is
946 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
947 the C compiler. There may be a small number of platforms on which correct
948 operation of this code cannot be guaranteed, so the code is not used: notably,
949 this applies to platforms where the C double format is not IEEE 754 binary64,
950 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
951 and Python's configure script is unable to determine how to change the FPU
952 precision. On these platforms conversions use the platform strtod and dtoa,
953 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000954
Georg Brandlba83f822010-03-14 09:50:54 +0000955- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
956 uses the correctly-rounded string <-> float conversions described above (when
957 available), and so produces correctly rounded results that will display nicely
958 under the float repr. There are two related small changes: (1) round now
959 accepts any class with an ``__index__()`` method for its second argument (but
960 no longer accepts floats for the second argument), and (2) an excessively
961 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
962 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000966- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00001109- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1110 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1111 but with at least one decimal point and with a default precision
1112 of 12. Previously, the behavior the same but with a default precision of 6.
1113 This more closely matches ``str()``, and reduces surprises when adding
1114 alignment flags to the empty presentation type. This also affects the new
1115 complex.__format__ in the same way.

1312
Georg Brandlba83f822010-03-14 09:50:54 +00001313- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1314 file objects with closefd=False. The file descriptor is still kept open but
1315 the file object behaves like a closed file. The ``FileIO`` object also got a

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001336- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001339- On windows, ``os.chdir()`` given unicode was not working if
1340 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1341 this code path is really executed because I cannot move to such directory on
1342 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001344- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1345 element is temporarily replaced with an equivalent frozenset. But the
1346 eventual KeyError would always report the empty ``frozenset()`` as the missing
1347 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001367- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1368 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1369 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1370 of using the replace error handler in PyUnicode_DecodeUTF8().
1371
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001372- Issue #3739: The unicode-internal encoder now reports the number of characters

1374
Georg Brandlba83f822010-03-14 09:50:54 +00001375- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1377 gives improved memory leak detection when running under Valgrind, while taking
1378 advantage of pymalloc at other times.

2629 import both normal and optimised versions of modules. test_heapq and
2630 test_warnings have been adjusted to use it, tests for other modules with both
2631 C and Python implementations in the stdlib can be adjusted to use it over
2632 time.

2641 should cause a test to be skipped are now done using import_module from test
2642 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002743- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2744
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002745- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2746 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2747 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2748 ``printf`` function, whereas PyString_FromFormat has an independent
2749 implementation and uses "%zd" on all platforms for size_t values.
2750 This makes a difference on win64, where ``printf`` needs "%Id" to display
2751 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002753- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2757 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002761- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002767 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002768 was correctly parsed but parsing of subsequent arguments failed.
2769
Vinay Sajip35e3b032008-09-01 14:33:59 +00002770- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002771 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2772 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2773 when given a tuple of classes as second argument, were looking up
2774 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2775 type object.
2776
Neal Norwitz18aa3882008-08-24 05:04:52 +00002777- Fix crashes on memory allocation failure found with failmalloc.

Guido van Rossumf8402962008-08-20 15:01:50 +00002922- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2923 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2924 extensions do not automatically benefit from the class attribute
2925 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2926 to their tp_flags field if they care. This is a backwards
2927 compatibility feature; in 3.0, all types will use the cache by
2928 default.
2929
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002930- Keyword arguments can now follow starred arguments. (``f(a, *args,
2931 keyword=23)`` is now valid syntax.)
2932
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002933- ctypes function pointers that are COM methods have a boolean True
2934 value again.
2935
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002936- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2937 by denying s# to parse objects that have a releasebuffer procedure,
2938 and introducing s*.
2939
Georg Brandl1e13ea92008-08-11 09:07:59 +00002940- Issue #3537: Fix an assertion failure when an empty but presized dict
2941 object was stored in the freelist.
2942
Mark Dickinsonb6467572008-08-04 21:30:09 +00002943- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2944 ValueError consistently across platforms.
2945
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002946- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2947 (64bit Unix, for example), unichr() would truncate its argument and return
2948 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2949
Neal Norwitze7d8be82008-07-31 17:17:14 +00002950- Apply security patches from Apple.
2951
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002952- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2953 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2954
Antoine Pitrou92f82162008-07-25 22:22:08 +00002955- Issue #1819: function calls with several named parameters are now on
2956 average 35% faster (as measured by pybench).
2957
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002958- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2959 the python debugger steps into a class statement: the free variables (local
2960 variables defined in an outer scope) would be deleted from the outer scope.
2961
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002962- Issue #2620: Overflow checking when allocating or reallocating memory
2963 was not always being done properly in some python types and extension
2964 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2965 all been updated to perform better checks and places in the code that
2966 would previously leak memory on the error path when such an allocation
2967 failed have been fixed.

2970-------
2971
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002972- Issue #3612: Added some missing basic types in ctypes.wintypes.
2973
Benjamin Petersone977ad42008-08-20 01:42:01 +00002974- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2975 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2976
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002977- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2978 version reported by these tools does not necessarily follow the python
2979 version numbering scheme, so the module is less strict when parsing it.
2980
Nick Coghlanf70385a2008-08-18 12:42:46 +00002981- Issue #2235: Added Py3k warnings for types which will become unhashable
2982 under the stricter __hash__ inheritance rules in 3.0. Several types
2983 which did not meet the rules for hash invariants and were already
2984 unhashable in 3.0 have now been explicitly flagged as unhashable in
2985 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2986 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2987
Brett Cannon88f801d2008-08-18 00:46:22 +00002988- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2989 imported into the module but exposed as part of the module's API.
2990
Brett Cannon7b96f072008-08-18 00:41:11 +00002991- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2992
Brett Cannon46225e72008-08-18 00:36:52 +00002993- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2994
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002995- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2996
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002997- Issue #3575: Incremental decoder's decode function now takes bytearray
2998 by using 's*' instead of 't#'.
2999
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003000- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003001 fails unicode conversion on 2nd parameter. (windows only)
3002
Facundo Batista94f243a2008-08-17 03:38:39 +00003003- Issue 2464. urllib2 now supports a malformation in the URL received
3004 in a redirect.
3005
Brett Cannonabe423e2008-08-16 21:47:07 +00003006- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003007 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003008
Facundo Batistaeb90b782008-08-16 14:44:07 +00003009- Issue #2776: fixed small issue when handling an URL with double slash
3010 after a 302 response in the case of not going through a proxy.
3011
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003012- Issue #2676: in the email package, content-type parsing was hanging on
3013 pathological input because of quadratic or exponential behaviour of a
3014 regular expression.
3015
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003016- Issue #3476: binary buffered reading through the new "io" library is now
3017 thread-safe.
3018
Brett Cannonbf3157b2008-08-14 05:00:03 +00003019- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3020 since mimetools itself is deprecated. Because modules are cached, all
3021 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3022
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003023- Issue #3134: shutil referenced undefined WindowsError symbol.
3024
Robert Schuppenies14646332008-08-10 11:01:53 +00003025- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3026 menu entries were not deleted.
3027
Brett Cannon83e81842008-08-09 23:30:55 +00003028- Copied the implementation of reduce() to _functools.reduce() to have a
3029 version that did not raise a DeprecationWarning under -3.
3030
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003031- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3032 a MemoryError rather than silently stop the iteration.
3033
Guido van Rossum59ce9012008-08-09 14:55:34 +00003034- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3035 to _sre.compile() will now be rejected. This should not affect anybody
3036 since the re.compile() function never generates invalid re-bytecode.
3037
Skip Montanaroa032bf42008-08-08 22:52:51 +00003038- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3039 upon first access it can be automatically initialized from the csv file if
3040 it wasn't initialized during instantiation.
3041
Brett Cannon3aa2a492008-08-06 22:28:09 +00003042- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3043 the reload() built-in has been removed.
3044
Brett Cannon7e30b672008-08-04 21:52:25 +00003045- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003046 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003053- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3054 raised an AttributeError.
3055
Benjamin Peterson01a24322008-07-28 23:35:27 +00003056- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003057 asking for a specific length. This problem only affected files opened
3058 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003059
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003060- Issue #3449: Update decimal module to use most recent specification
3061 (v. 1.68) and tests (v. 2.58) from IBM.
3062
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003063- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3064
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003065- Issue 1592: Improve error reporting when operations are attempted
3066 on a closed shelf.

3071
3072- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3073 invalid arguments.
3074
3075- Issue #3302: Fix several crashes when calling locale's gettext functions
3076 with None arguments.
3077
3078- Issue #3389: Allow resolving dotted names for handlers in logging
3079 configuration files.
3080
3081- Deprecate the sunaudio module for removal in Python 3.0.
3082
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003083- Issue #3394: zipfile.writestr sets external attributes when passed a
3084 file name rather than a ZipInfo instance, so files are extracted with
3085 mode 0600 rather than 000 under Unix.
3086
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003087- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3088 argument in python 2.5, this broke code that subclassed Popen to include its
3089 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3097-------------
3098
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003099- Issue #2235: the C API function PyObject_HashNotImplemented and its
3100 interaction with the tp_hash slot (added in 2.6b2) are now documented
3101
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003102- Issue #643841: The language reference now provides more detailed
3103 coverage of the lookup process for special methods. The disclaimers
3104 regarding lack of coverage of new-style classes have also been
3105 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003113Core and Builtins
3114-----------------
3115
Georg Brandl3e483f62008-07-16 22:57:41 +00003116- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3117 its methods now allow for items objects that can be converted to
3118 an integer using operator.index().
3119
Mark Dickinson64b7e502008-07-16 09:40:03 +00003120- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3121 produced a ValueError instead of giving the correct float.
3122
Eric Smitha5fa5a22008-07-16 00:11:49 +00003123- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3124 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3125
Mark Dickinson7103aa42008-07-15 19:08:33 +00003126- Issue #3008: the float type has a new instance method 'float.hex'
3127 and a new class method 'float.fromhex' to convert floating-point
3128 numbers to and from hexadecimal strings, respectively.
3129
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003130- Issue #2235: __hash__ is once again inherited by default. To allow
3131 collections.Hashable to remain meaningful in the presence of the
3132 default hash implementation (object.__hash__), it is now possible
3133 to explicit block inheritance of hash by setting __hash__=None at
3134 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3135 level.
3136
Nick Coghlanb028f502008-07-13 14:52:36 +00003137- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3138 the parent module cannot be found while performing an absolute import.
3139 This means that an incorrectly defined __package__ attribute will
3140 now only prevent relative imports in that module rather than causing
3141 all imports from that module to fail.
3142
Nick Coghlan14ff9942008-07-08 14:21:42 +00003143- Issue #2517: Allow unicode messages in Exceptions again by correctly
3144 bypassing the instance dictionary when looking up __unicode__ on
3145 new-style classes.
3146
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003147- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3148 set to a custom object whose write() method happens to install
3149 another file in sys.stdout.
3150
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003151- Issue #3088: Corrected a race condition in classes derived from
3152 threading.local: the first member set by a thread could be saved in
3153 another thread's dictionary.
3154
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003155- Issue #3004: Minor change to slice.indices(): the start and stop
3156 arguments are now treated identically, making the behaviour easier
3157 to describe and understand. For example, slice(None, -10,
3158 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3159 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3160 10, -1).
3161
Georg Brandl278fc502008-07-19 12:46:12 +00003162- Issue #3219: Calling a function with repeated keyword arguments,
3163 f(a=2, a=23), would not cause a syntax error. This was a regression
3164 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003165
Georg Brandl278fc502008-07-19 12:46:12 +00003166- Issue #2862: Make int and float freelist management consistent with
3167 other freelists. Changes their CompactFreeList apis into
3168 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003169

3171-------
3172
Thomas Heller57adf222008-08-14 19:10:48 +00003173- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3174 api functions without holding the GIL, which could lead to a fatal
3175 error when they failed.
3176
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003177- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003185- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3186 ForkingPickler.register() to resolve conflict with ctypes.
3187
Vinay Sajip51e65192008-07-18 09:01:10 +00003188- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003189
Thomas Heller880f5292008-07-15 19:39:38 +00003190- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3191 a valid dlerror() message.
3192
Thomas Heller2bad6572008-07-15 17:19:50 +00003193- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3194 incomplete structure was created.
3195
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003196- Issue #3339: dummy_thread.acquire() should not return None.
3197
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003198- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3199
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003200- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003201
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003202- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3203 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003204 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003205 content-length. The problem had been corrected in the 2.4 branch, but never
3206 merged into trunk.
3207
Georg Brandle78fbcc2008-07-05 10:13:36 +00003208- Issue #2663: add filtering capability to shutil.copytree().

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003612- On MacOS X it is now possible to install the framework in 64-bit
3613 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003614 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003615
3616 This is controlled by the configure argument ``--with-universal-archs``:
3617
3618 - ``--with-universal-archs=all``: install 4-way universal
3619
3620 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3621
3622 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3623
3624 This option should be used in combination with ``--enable-universalsdk=``.
3625
3626 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003676- Issue #1631171: Re-implement the 'warnings' module in C (the
3677 original Python code has been kept as backup). This will allow for
3678 using the 'warning's machinery in such places as the parser where
3679 use of pure Python code is not possible. Both the ``showarning()``
3680 and ``formatwarning()`` gain an optional 'line' argument which is
3681 not called by default for backwards-compatibility reasons. Setting
3682 ``warnings.showwarning()`` to an implementation that lacks support
3683 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003746- Issue #2550: The approach used by client/server code for obtaining
3747 ports to listen on in network-oriented tests has been refined in an
3748 effort to facilitate running multiple instances of the entire
3749 regression test suite in parallel without issue.
3750 test_support.bind_port() has been fixed such that it will always
3751 return a unique port -- which wasn't always the case with the
3752 previous implementation, especially if socket options had been set
3753 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3754 new implementation of bind_port() will actually raise an exception
3755 if it is passed an AF_INET/SOCK_STREAM socket with either the
3756 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3757 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3758 the socket it's been passed. This currently only applies to
3759 Windows. This option prevents any other sockets from binding to the
3760 host/port we've bound to, thus removing the possibility of the
3761 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3762 when a second SOCK_STREAM socket binds and accepts to a host/port
3763 that's already been bound by another socket. The optional preferred
3764 port parameter to bind_port() has been removed. Under no
3765 circumstances should tests be hard coding ports!
3766
3767 test_support.find_unused_port() has also been introduced, which will
3768 pass a temporary socket object to bind_port() in order to obtain an
3769 unused port. The temporary socket object is then closed and
3770 deleted, and the port is returned. This method should only be used
3771 for obtaining an unused port in order to pass to an external program
3772 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3773 a parameter to a server-oriented class that doesn't give you direct
3774 access to the underlying socket used.

4052Core and builtins
4053-----------------
4054
Fred Drakea8ee94b2008-03-01 02:45:07 +00004055- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004056 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004057
Georg Brandlad61bc82008-02-23 15:11:18 +00004058- Issue #2067: file.__exit__() now calls subclasses' close() method.
4059
4060- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004061
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004062- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004063 issue 215555 for a discussion.
4064
Eric Smitha73fbe72008-02-23 03:09:44 +00004065- Added the future_builtins module, which contains hex() and oct().
4066 These are the PEP 3127 version of these functions, designed to be
4067 compatible with the hex() and oct() builtins from Python 3.0. They
4068 differ slightly in their output formats from the existing, unchanged
4069 Python 2.6 builtins. The expected usage of the future_builtins
4070 module is:
4071 from future_builtins import hex, oct
4072
Eric Smith7ef40bf2008-02-20 23:34:22 +00004073- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4074 exponents for exponents with absolute value < 100. Follows C99
4075 standard. This is a change on Windows, which would use 3 digits.
4076 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4077 so that any alterations it does to the resulting string will be
4078 available in stringlib/formatter.h (for float.__format__).
4079
Eric Smith5a3c1352008-02-19 13:21:56 +00004080- Implemented PEP 3101, Advanced String Formatting. This adds a new
4081 builtin format(); a format() method for str and unicode; a
4082 __format__() method to object, str, unicode, int, long, float, and
4083 datetime; the class string.Formatter; and the C API
4084 PyObject_Format().
4085
Georg Brandl3ee81df2008-05-17 18:14:43 +00004086- Fixed several potential crashes, all caused by specially crafted
4087 __del__ methods exploiting objects in temporarily inconsistent
4088 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004089
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004090- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004091 prevent a possible crash: an Abstract Base Class would try to access
4092 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004093
Georg Brandl3ee81df2008-05-17 18:14:43 +00004094- Fixed repr() and str() of complex numbers with infinity or nan as
4095 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004096
Georg Brandl3ee81df2008-05-17 18:14:43 +00004097- Clear all free lists during a gc.collect() of the highest generation
4098 in order to allow pymalloc to free more arenas. Python may give back
4099 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004100
Georg Brandl3ee81df2008-05-17 18:14:43 +00004101- Issue #2045: Fix an infinite recursion triggered when printing a
4102 subclass of collections.defaultdict, if its default_factory is set
4103 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004104
Christian Heimesf75dbef2008-02-08 00:11:31 +00004105- Fixed a minor memory leak in dictobject.c. The content of the free
4106 list was not freed on interpreter shutdown.
4107
Georg Brandl21e99f42010-03-07 15:23:59 +00004108- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004109 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004110
Georg Brandl3ee81df2008-05-17 18:14:43 +00004111- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4112 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004113 to compact the internal free lists of pre-allocted ints and floats.
4114
Georg Brandl3ee81df2008-05-17 18:14:43 +00004115- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4116 calls. Python expected the return type int but the fork familie
4117 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004118
Georg Brandl3ee81df2008-05-17 18:14:43 +00004119- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4120 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004121
Georg Brandl3ee81df2008-05-17 18:14:43 +00004122- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4123 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004124
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4126 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004127
Georg Brandl3ee81df2008-05-17 18:14:43 +00004128- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4129 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004130
Georg Brandl3ee81df2008-05-17 18:14:43 +00004131- Patch #1473257: generator objects gain a gi_code attribute. This is
4132 the same object as the func_code attribute of the function that
4133 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004134
Georg Brandl3ee81df2008-05-17 18:14:43 +00004135- Issue #1920: "while 0" statements were completely removed by the
4136 compiler, even in the presence of an "else" clause, which is
4137 supposed to be run when the condition is false. Now the compiler
4138 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004139
Guido van Rossumeead05f2008-01-24 18:21:02 +00004140- A few crashers fixed: weakref_in_del.py (issue #1377858);
4141 loosing_dict_ref.py (issue #1303614, test67.py);
4142 borrowed_ref_[34].py (not in tracker).
4143
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004144- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004145 suppressed while an extension is loaded by calling SetErrorMode in
4146 dynload_win.c. The error is still reported properly.
4147
Georg Brandl3ee81df2008-05-17 18:14:43 +00004148- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004149 several extension methods and modules do not work without unicode
4150 support.
4151
Georg Brandl26543b12008-01-21 18:36:51 +00004152- Issue #1882: when compiling code from a string, encoding cookies in the
4153 second line of code were not always recognized correctly.
4154
Georg Brandl14404b62008-01-19 19:27:05 +00004155- Issue #1679: "0x" was taken as a valid integer literal.
4156
Georg Brandl6caad7d2008-01-26 14:19:22 +00004157- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004158 added.
4159
Christian Heimesc94e2b52008-01-14 04:13:37 +00004160- sys.float_info / PyFloat_GetInfo: The floating point information
4161 object was converted from a dict to a specialized structseq object.
4162
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163- Patch #1816: Added sys.flags structseq. It exposes the status of
4164 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004165
Georg Brandl3ee81df2008-05-17 18:14:43 +00004166- Objects/structseq.c: Implemented new structseq representation. The
4167 patch makes structseqs (e.g. the return value of os.stat) more
4168 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004169
Georg Brandl3ee81df2008-05-17 18:14:43 +00004170- Patch #1700288: added a type attribute cache that caches method
4171 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004172
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004173- Bug #1776: __import__() no longer accepts filenames on any platform.
4174 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004175
Georg Brandlaed6c662008-01-07 17:25:53 +00004176- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4177
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4179 envvar and sys.dont_write_bytecode attribute. All these can be set
4180 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004181
Georg Brandl3ee81df2008-05-17 18:14:43 +00004182- Improve some exception messages when Windows fails to load an
4183 extension module. Now we get for example '%1 is not a valid Win32
4184 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004185
Georg Brandl3ee81df2008-05-17 18:14:43 +00004186- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004188- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4189 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004190
Christian Heimes0a8143f2007-12-18 23:22:54 +00004191- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192 and INF. float("nan"), float("inf") and float("-inf") now work on
4193 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004194
Georg Brandl3ee81df2008-05-17 18:14:43 +00004195- Compiler now generates simpler and faster code for dictionary
4196 literals. The oparg for BUILD_MAP now indicates an estimated
4197 dictionary size. There is a new opcode, STORE_MAP, for adding
4198 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004199
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004205- Issue #1538: Avoid copying string in split/rsplit if the split char
4206 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004207
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004208- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004209 SystemError.
4210
Nick Coghlanef01d822007-12-03 12:55:17 +00004211- PEP 366: Allow explicit relative imports when executing modules
4212 inside packages with the -m switch via a new module level
4213 __package__ attribute.
4214
Georg Brandl3ee81df2008-05-17 18:14:43 +00004215- Issue #1402: Fix a crash on exit, when another thread is still
4216 running, and if the deallocation of its frames somehow calls the
4217 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004218

4228 file can now be directly executed by passing their name to the
4229 interpreter. The directory/zipfile is automatically inserted as the
4230 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004231
Georg Brandl3ee81df2008-05-17 18:14:43 +00004232- Issue #1265: Fix a problem with sys.settrace, if the tracing
4233 function uses a generator expression when at the same time the
4234 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004235
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004236- sets and frozensets now have an isdisjoint() method.
4237
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004238- optimize the performance of builtin.sum().
4239
Neal Norwitz44f326e2007-10-05 05:29:17 +00004240- Fix warnings found by the new version of the Coverity checker.
4241
Georg Brandl21e99f42010-03-07 15:23:59 +00004242- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004243 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4244 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004245
Georg Brandl3ee81df2008-05-17 18:14:43 +00004246- Issue #1686386: Tuple's tp_repr did not take into account the
4247 possibility of having a self-referential tuple, which is possible
4248 from C code. Nor did object's tp_str consider that a type's tp_str
4249 could do something that could lead to an inifinite recursion.
4250 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4251 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004253- Issue #1164: It was possible to trigger deadlock when using the
4254 'print' statement to write to a file since the GIL was not released
4255 as needed. Now PyObject_Print() does the right thing along with
4256 various tp_print implementations of the built-in types and those in
4257 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004258
Georg Brandl3ee81df2008-05-17 18:14:43 +00004259- Issue #1147: Exceptions were directly allowing string exceptions in
4260 their throw() method even though string exceptions no longer
4261 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004262

Brett Cannon1e534b52007-09-07 04:18:30 +00004266- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004267 PyObject_Call() never calling back out to Python code to trigger
4268 recursion depth updates/checks. Required the creation of a static
4269 RuntimeError instance in case normalizing an exception put the
4270 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00004286- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004287 __*__ attributes. (Some already existed, e.g., __doc__ and
4288 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004289
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004290- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00004297 "except E as target:". This is to provide forwards compatibility
4298 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004299
Brett Cannon229cee22007-05-05 01:34:02 +00004300- Deprecate BaseException.message as per PEP 352.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004306 setting a plain string, ie don't expand to single letter identifiers.
4307
Raymond Hettinger13936692007-04-11 18:40:58 +00004308- Request #1191699: Slices can now be pickled.

4318
Guido van Rossum143b5642007-03-23 04:58:42 +00004319- Bug #1683368: The object.__init__() and object.__new__() methods are
4320 now stricter in rejecting excess arguments. The only time when
4321 either allows excess arguments is when it is not overridden and the
4322 other one is. For backwards compatibility, when both are
4323 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004324 warning later). Also, type.__init__() insists on the same signature
4325 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004326
Georg Brandl3ee81df2008-05-17 18:14:43 +00004327- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4328 object to complex using its __complex__() method before falling back
4329 to the __float__() method. Therefore, the functions in the cmath
4330 module now can operate on objects that define a __complex__()
4331 method.

4348
Georg Brandl7b9c5552007-03-12 14:30:05 +00004349- Bug #1678647: write a newline after printing an exception in any
4350 case, even when converting the value to a string failed.
4351
Georg Brandl871f1bc2007-03-12 13:17:36 +00004352- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004353 its argument, if it exists. If not, it will work like before. This
4354 allows customizing the output of dir() in the presence of a
4355 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004356

4365 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004366
Georg Brandlaa2321b2007-03-07 00:40:28 +00004367- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004368 makes the filenames the warning module prints much more sensible
4369 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004370

Georg Brandl0fca97a2007-03-05 22:28:08 +00004382- Patch #1674228: when assigning a slice (old-style), check for the
4383 sq_ass_slice instead of the sq_slice slot.
4384
Georg Brandl3ee81df2008-05-17 18:14:43 +00004385- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00005011- unittest now verifies more of its assumptions. In particular,

5013 accepted in TestSuite.addTest(). This should cause no
5014 incompatibility since it never made sense with ordinary subclasses
5015 -- the failure just occurred later, with a more cumbersome
5016 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005297- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5298 with RFC 3207 and forgets any knowledge obtained from the server not
5299 obtained from the TLS negotiation itself. Patch contributed by Bill
5300 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005301
Georg Brandl3ee81df2008-05-17 18:14:43 +00005302- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005303 that the SMTP.starttls() caller no longer needs to call ehlo()
5304 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005305 does not claim to support starttls. Adds the
5306 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005405 time so that opening a database previously created with the DB_DUP
5406 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5407 opens. Specifically: dictionary assignment to a DB object will
5408 replace all values for a given key when the database allows
5409 duplicate values. DB users should use DB.put(k, v) when they want
5410 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005411

5417 characters with ASCII value less than 32. Also, it correctly quotes
5418 dots only if they occur on a single line, as opposed to the previous
5419 behavior of quoting dots if they are the second character of any
5420 line.

5743-----
5744
Georg Brandl3ee81df2008-05-17 18:14:43 +00005745- Unified naming convention for free lists and their limits. All free
5746 lists in Object/ are named ``free_list``, the counter ``numfree``
5747 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5748 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005749
Georg Brandl3ee81df2008-05-17 18:14:43 +00005750- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5751 to ``PyTuple_SetItem``, it can be used to populate a brand new
5752 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005753
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005754- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005755
Georg Brandl3ee81df2008-05-17 18:14:43 +00005756- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5757 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5758 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005759
5760- Patch #1720595: add T_BOOL to the range of structmember types.
5761
5762- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5763 ``PyFloat_GetInfo()`` to the float API.
5764
Georg Brandl3ee81df2008-05-17 18:14:43 +00005765- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5766 of w# format code incorrectly truncated the length to an int, even
5767 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5768 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005769
Georg Brandl3ee81df2008-05-17 18:14:43 +00005770- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5771 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005772
Georg Brandl3ee81df2008-05-17 18:14:43 +00005773- PEP 3123: Provide forward compatibility with Python 3.0, while
5774 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5775 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005776
Georg Brandl3ee81df2008-05-17 18:14:43 +00005777- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5778 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005779
5780- Patch #1733960: Allow T_LONGLONG to accept ints.
5781
5782- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5783
Christian Heimes000a0742008-01-03 22:16:32 +00005784- Added a new API function ``PyImport_ImportModuleNoBlock``.
5785
Georg Brandl6caad7d2008-01-26 14:19:22 +00005786- Bug #1637022: Prefix AST symbols with _Py_.
5787
5788- Fix some leftovers from the conversion from int to Py_ssize_t
5789 (relevant to strings and sequences of more than 2**31 items).
5790
5791- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5792 outside of pystate.c and should not be necessary.
5793
Georg Brandl3ee81df2008-05-17 18:14:43 +00005794- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5795 absolute imports. In earlier versions they might have used relative
5796 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005797
Georg Brandl3ee81df2008-05-17 18:14:43 +00005798- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5799 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005800
Georg Brandl3ee81df2008-05-17 18:14:43 +00005801- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5802 macro so it can be used as an expression.

5807
Georg Brandl3ee81df2008-05-17 18:14:43 +00005808- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5809 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5810 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5811 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005812
Georg Brandl3ee81df2008-05-17 18:14:43 +00005813- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5814 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005826- Removed the macfs module. It had been deprecated since Python 2.5.
5827 This lead to the deprecation of macostools.touched() as it relied
5828 solely on macfs and was a no-op under OS X.
