11-----------------
12
Antoine Pitrou5b629422011-12-23 12:40:16 +010013- Issue #13577: Built-in methods and functions now have a __qualname__.
14 Patch by sbt.
15
Antoine Pitrou093ce9c2011-12-16 11:24:27 +010016- Issue #6695: Full garbage collection runs now clear the freelist of set
17 objects. Initial patch by Matthias Troffaes.
18
Antoine Pitroue0e27352011-12-15 14:31:28 +010019- Fix OSError.__init__ and OSError.__new__ so that each of them can be
20 overriden and take additional arguments (followup to issue #12555).
21
Antoine Pitrou2e872082011-12-15 14:15:31 +010022- Fix the fix for issue #12149: it was incorrect, although it had the side
23 effect of appearing to resolve the issue. Thanks to Mark Shannon for
24 noticing.
25
Alexandre Vassalotti3bfc65a2011-12-13 13:08:09 -050026- Issue #13505: Pickle bytes objects in a way that is compatible with
27 Python 2 when using protocols <= 2.
28
Barry Warsaw9f571352011-12-05 16:45:02 -050029- Issue #11147: Fix an unused argument in _Py_ANNOTATE_MEMORY_ORDER. (Fix
30 given by Campbell Barton).
31

33 pickle protocol >= 3. The old reduction format is kept with older protocols
34 in order to allow unpickling under Python 2. Patch by Irmen de Jong.
35
Antoine Pitrou11942a52011-11-28 19:08:36 +010036- Issue #7111: Python can now be run without a stdin, stdout or stderr
37 stream. It was already the case with Python 2. However, the corresponding
38 sys module entries are now set to None (instead of an unusable file object).
39
Antoine Pitrouf0effe62011-11-26 01:11:02 +010040- Issue #11849: Ensure that free()d memory arenas are really released
41 on POSIX systems supporting anonymous memory mappings. Patch by
42 Charles-François Natali.
43
Victor Stinnercad939b2011-11-25 20:11:54 +010044- Issue #13452: PyUnicode_EncodeDecimal() doesn't support error handlers
Victor Stinner6345be92011-11-25 20:09:01 +010045 different than "strict" anymore. The caller was unable to compute the
46 size of the output buffer: it depends on the error handler.
47
Antoine Pitrou86a36b52011-11-25 18:56:07 +010048- PEP 3155 / issue #13448: Qualified name for classes and functions.

57 to allow compiling extension modules with -Wswitch-enum on gcc.
58 Initial patch by Floris Bruynooghe.
59
Antoine Pitrouf34a0cd2011-11-18 20:14:34 +010060- Issue #10227: Add an allocation cache for a single slice object. Patch by
61 Stefan Behnel.
62
Antoine Pitrou56a220a2011-11-16 00:56:10 +010063- Issue #13393: BufferedReader.read1() now asks the full requested size to
64 the raw stream instead of limiting itself to the buffer size.
65
Antoine Pitrou28e401e2011-11-15 19:15:19 +010066- Issue #13392: Writing a pyc file should now be atomic under Windows as well.
67
Antoine Pitrou5418ee02011-11-15 01:42:21 +010068- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
69 already accepts them).
70
Antoine Pitrou9a812cb2011-11-15 00:00:12 +010071- Issue #13389: Full garbage collection passes now clear the freelists for
72 list and dict objects. They already cleared other freelists in the
73 interpreter.
74
Brian Curtin52fbea12011-11-06 13:41:17 -060075- Issue #13327: Remove the need for an explicit None as the second argument
Brian Curtin304a1652011-11-07 16:30:01 -060076 to os.utime, os.lutimes, os.futimes, os.futimens, os.futimesat, in
77 order to update to the current time. Also added keyword argument
78 handling to os.utimensat in order to remove the need for explicit None.
Brian Curtin52fbea12011-11-06 13:41:17 -060079
Amaury Forgeot d'Arc864741b2011-11-06 15:10:48 +010080- Issue #13350: Simplify some C code by replacing most usages of

105 object identity).
106
Nick Coghlande31b192011-10-23 22:04:16 +1000107- Issue #1294232: In a few cases involving metaclass inheritance, the

865 Condition, etc.) used to be factory functions returning instances of hidden
866 classes (_Thread, _Condition, etc.), because (if Guido recalls correctly) this

Ned Deily657b2de2011-06-28 19:51:30 -07001013- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1014 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1015 interpreter process. This could cause failures in non-Distutils subprocesses
1016 and was unreliable since tests or user programs could modify the interpreter
1017 environment after Distutils set it. Instead, have Distutils set the the
1018 deployment target only in the environment of each build subprocess. It is
1019 still possible to globally override the default by setting
1020 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1021 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -07001022 was built. Also, implement the same handling in packaging.

1813 the amount of time needed to run the tests. "make test" and "make quicktest"
1814 now include some resource-intensive tests, but no longer run the test suite

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002929 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

3275
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00003276- Issue #10068: Global objects which have reference cycles with their module's
3277 dict are now cleared again. This causes issue #7140 to appear again.
3278
Victor Stinner257d38f2010-10-09 10:12:11 +00003279- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00003280 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00003281
Georg Brandl27a28582010-10-10 09:49:21 +00003282- ast.literal_eval() can now handle negative numbers. It is also a little more
3283 liberal in what it accepts without compromising the safety of the evaluation.
3284 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00003285
Benjamin Peterson970d1882010-10-02 17:55:47 +00003286- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
3287 result metaclasses can now be ABCs (see #9533).
3288
Victor Stinneraef57e32010-10-02 11:50:49 +00003289- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
3290
Victor Stinner5593d8a2010-10-02 11:11:27 +00003291- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00003292 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
3293 32 bits wchar_t (eg. Linux in narrow build).

Victor Stinner137c34c2010-09-29 10:25:54 +00003298- Issue #9979: Create function PyUnicode_AsWideCharString().
3299
Brett Cannon5305a992010-09-27 21:08:38 +00003300- Issue #7397: Mention that importlib.import_module() is probably what someone
3301 really wants to be using in __import__'s docstring.
3302
Georg Brandl27a28582010-10-10 09:49:21 +00003303- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
3304 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00003305
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00003306- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00003307 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00003308
Brian Curtine8e4b3b2010-09-23 20:04:14 +00003309- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
3310
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00003311- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
3312 threads are still running. Instead, reinitialize the GIL on a second call to
3313 Py_Initialize().
3314
Georg Brandl27a28582010-10-10 09:49:21 +00003315- All SyntaxErrors now have a column offset and therefore a caret when the error
3316 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00003317
Brett Cannonbc2eff32010-09-19 21:39:02 +00003318- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3319 module that was imported, but instead gets the module from sys.modules.
3320
Nick Coghlan37ee8502010-12-03 14:26:13 +00003321- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00003322 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00003323
Georg Brandl27a28582010-10-10 09:49:21 +00003324- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3325 with a non-empty format string. This is an effort to future-proof user
3326 code. If a derived class does not currently implement __format__ but later
3327 adds its own __format__, it would most likely break user code that had
3328 supplied a format string. This will be changed to a DeprecationWaring in
3329 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00003330
Antoine Pitrou1df15362010-09-13 14:16:46 +00003331- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3332 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3333 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3334
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003335- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3336 functions from the libc caused the methods .upper() and lower() to become
3337 locale aware and created subtly wrong results.
3338
Georg Brandl27a28582010-10-10 09:49:21 +00003339- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3340 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003341
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003342- Issue #4617: Previously it was illegal to delete a name from the local
3343 namespace if it occurs as a free variable in a nested block. This limitation
3344 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3345
Georg Brandl27a28582010-10-10 09:49:21 +00003346- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3347 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3348 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3349 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00003350
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003351- Issue #9757: memoryview objects get a release() method to release the
3352 underlying buffer (previously this was only done when deallocating the
3353 memoryview), and gain support for the context management protocol.
3354
Antoine Pitrou079ce542010-09-08 12:37:10 +00003355- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3356 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00003372- Issue #4661: email can now parse bytes input and generate either converted
3373 7bit output or bytes output. Email version bumped to 5.1.0.
3374
Antoine Pitrou59fdd672010-10-08 10:37:08 +00003375- Issue #1589: Add ssl.match_hostname(), to help implement server identity
3376 verification for higher-level protocols.
3377
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00003378- Issue #9759: GzipFile now raises ValueError when an operation is attempted
3379 after the file is closed. Patch by Jeffrey Finkelstein.
3380
Éric Araujo6108bf52010-10-04 23:52:37 +00003381- Issue #9042: Fix interaction of custom translation classes and caching in
3382 gettext.
3383
Éric Araujoef777bd2010-10-05 00:04:20 +00003384- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003385 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003386 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003387 replacement for old handle_accept() and avoids the user to call accept()
3388 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00003390- Issue #9065: tarfile no longer uses "root" as the default for the uname and

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00003411- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00003412 retry the select() loop instead of bailing out. This is because select() can
3413 incorrectly report a socket as ready for reading (for example, if it received
3414 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00003471- Issue #9854: The default read() implementation in io.RawIOBase now handles
3472 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00003473
Georg Brandl27a28582010-10-10 09:49:21 +00003474- Issue #1552: socket.socketpair() now returns regular socket.socket objects
3475 supporting the whole socket API (rather than the "raw" _socket.socket
3476 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00003477

Éric Araujod8c73c62011-03-21 03:15:22 +01003481- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00003482 them handle recursive calls within the same thread.

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003494- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003495 it possible for the user to create self-referencing ordered dictionaries which
3496 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003497 approach of using weakref proxies so that reference cycles never get created
3498 in the first place.
3499
Victor Stinnercb043522010-09-10 23:49:04 +00003500- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
3501 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00003502 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00003503
Georg Brandl27a28582010-10-10 09:49:21 +00003504- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3505 environment variable to set the filesystem encoding at Python startup.
3506 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3507 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003508
Georg Brandl27a28582010-10-10 09:49:21 +00003509- Issue #9410: Various optimizations to the pickle module, leading to speedups
3510 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
3511 initial patch by Alexandre Vassalotti.

Vinay Sajip121a1c42010-09-08 10:46:15 +00003516- Logging: Added QueueHandler class to facilitate logging usage with
3517 multiprocessing.
3518
Georg Brandl27a28582010-10-10 09:49:21 +00003519- Issue #9707: Rewritten reference implementation of threading.local which is
3520 friendlier towards reference cycles. This change is not normally visible
3521 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003522
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003523- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3524 still return the id of the parent process after it has exited. This process
3525 id may even have been reused by another unrelated process.
3526
Georg Brandl27a28582010-10-10 09:49:21 +00003527- Issue #9792: In case of connection failure, socket.create_connection() would
3528 swallow the exception and raise a new one, making it impossible to fetch the
3529 original errno, or to filter timeout errors. Now the original error is
3530 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003532- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3533 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3534 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003536- Updates to the random module:
3537
Georg Brandl27a28582010-10-10 09:49:21 +00003538 * Document which parts of the module are guaranteed to stay the same across
3539 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00003541 * Update the seed() method to use all of the bits in a string instead of just
3542 the hash value. This makes better use of the seed value and assures the
3543 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003544
Georg Brandl27a28582010-10-10 09:49:21 +00003545 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3546 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3547 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003548
3549 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003568- hashlib has two new constant attributes: algorithms_guaranteed and
3569 algorithms_avaiable that respectively list the names of hash algorithms
3570 guaranteed to exist in all Python implementations and the names of hash
3571 algorithms available in the current process.
3572

Georg Brandl649971e2010-09-05 17:06:50 +00003663- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
3664 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our

Georg Brandl649971e2010-09-05 17:06:50 +00003676- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3677 now removed, since their effect was inexistent in 3.x (the default encoding is
3678 hardcoded to utf-8 and cannot be changed).

3700 return characters from the full Unicode range, even on narrow unicode builds
3701 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3702 in Python is that unicodedata.numeric() now returns the correct value for
3703 large code points, and repr() may consider more characters as printable.
3704
Victor Stinner6c00c142010-08-17 23:37:11 +00003705- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

3707 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
3708 function.

Georg Brandl62069d32010-07-31 08:56:11 +00004084 start byte and the continuation byte(s) are now considered invalid, instead of
4085 the number of bytes specified by the start byte. E.g.:
4086 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
4087 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
4088 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
4089 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00004119- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00004120 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

4133 TypeError instead of giving a DeprecationWarning when a float is parsed using
4134 the 'L' code (for long long). (All other integer codes already raise
4135 TypeError in this case.)

4139 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
4140
Georg Brandl62069d32010-07-31 08:56:11 +00004141- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol

Georg Brandl62069d32010-07-31 08:56:11 +00004145 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004146 like bytearray.
4147
Georg Brandl62069d32010-07-31 08:56:11 +00004148- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no

4157 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
4158 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
4159 equal value.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004161- Issue #8748: Fix two issues with comparisons between complex and integer
4162 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00004163 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
4164 (2) The comparison raised an OverflowError for large integers, leading to
4165 unpredictable exceptions when combining integers and complex objects in sets
4166 or dicts.

4299 similar optimization already existed which turned a list of constants into a

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00004468- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
4469 variable argument list. `Py_VA_COPY` is equivalent to C99
4470 `va_copy`, but available on all python platforms.
4471
Mark Dickinsone6fc7402010-08-06 18:55:26 +00004472- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
4473 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
4474 "step = -step" when reversing a slice.
4475
Georg Brandl62069d32010-07-31 08:56:11 +00004476- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the

4483
Antoine Pitrou8689a102010-04-01 16:53:15 +00004484- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00004485 function declaration, which was kept for backwards compatibility reasons, is
4486 now removed (the macro was introduced in 1997!).

Georg Brandl62069d32010-07-31 08:56:11 +00004495 PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
4496 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4497 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004498 to match the behaviour of the other integer format codes.
4499

Georg Brandl62069d32010-07-31 08:56:11 +00004508- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
4509 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
4510 accessing the d_type and d_name members of structures using PyDescr_COMMON.
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +00004511

4523 ``const char *`` as the string is stored beyond the call.
4524
Georg Brandl62069d32010-07-31 08:56:11 +00004525- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4526 allocator will be automatically disabled when running under Valgrind. This
4527 gives improved memory leak detection when running under Valgrind, while taking
4528 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00004603 simply clearing the entire cache on overflow to forgetting the least recently
4604 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004605 applications that use a lot of regular expressions and limits the impact of
4606 the performance hit anytime the cache is exceeded.

4619 module is renamed to `_datetime` and if available, overrides all classes
4620 defined in datetime with fast C impementation. Python implementation is based
4621 on the original python prototype for the datetime module by Tim Peters with
4622 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00004860- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4861 operation raises multiple signals and more than one of those signals is
4862 trapped, the specification determines the order in which the signals should be
4863 handled. In many cases this order wasn't being followed, leading to the wrong
4864 Python exception being raised.

5021 return a result based on the numeric values of the operands; previously they

5085 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00005087- subprocess.Popen now has restore_signals and start_new_session features. The
5088 default of restore_signals=True is a new behavior compared to earlier Python
5089 versions. This means that signals such as SIGPIPE are not ignored by default
5090 in subprocesses launched by Python (Issue #1652).

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005583- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005584 compared to other unix systems. In particular, os.getgroups() does not reflect
5585 any changes made using os.setgroups() but basicly always returns the same
5586 information as the id command. os.getgroups() can now return more than 16
5587 groups on MacOSX.

5613 Prior to this change, timezone adjustment in utctimetuple() could produce
5614 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

5618 directive. When the ``%z`` directive is present in the format string, an
5619 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5620 ``datetime.timezone`` instance constructed from the parsed offset. If both
5621 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5622 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005624- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005625 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5626 ``datetime.timezone``, return fixed name and UTC offset from their
5627 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5628 returns ``None``. A class attribute, ``utc`` contains an instance
5629 representing the UTC timezone. Original patch by Rafe Kaplan.

5646 with an improved 'binary-split' algorithm that uses fewer multiplications and
5647 allows many of the multiplications to be performed using plain C integer
5648 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00005654- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5655 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005656 the result is now always correctly rounded, and is equivalent to ``td /
5657 timedelta(seconds=1)``.

5666 integer format code, struct.pack first attempts to convert the non-integer
5667 using its __index__ method. If that method is non-existent or raises
5668 TypeError it goes on to try the __int__ method, as described below.

6050
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00006051- Issue #6137: The pickle module now translates module names when loading
6052 or dumping pickles with a 2.x-compatible protocol, in order to make data
6053 sharing and migration easier. This behaviour can be disabled using the
6054 new `fix_imports` optional argument.

6107
Eric Smith41669ca2009-05-23 14:23:22 +00006108- Issue #6089: Fixed str.format with certain invalid field specifiers
6109 that would raise SystemError.
6110
Raymond Hettinger2bcde142009-05-29 04:52:27 +00006111- Issue #5982: staticmethod and classmethod now expose the wrapped
6112 function with __func__.
6113
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00006114- Added support for multiple context managers in the same with-statement.
6115 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00006117- Issue #5829: complex("1e500") no longer raises OverflowError. This
6118 makes it consistent with float("1e500") and interpretation of real
6119 and imaginary literals.
6120
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00006121- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

6124
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00006125- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
6126 (1) inf and nan strings with trailing whitespace were incorrectly
6127 rejected; (2) parsing of strings representing infinities and nans
6128 was locale aware; and (3) the interpretation of fromhex('-nan')
6129 didn't match that of float('-nan').

6135
R. David Murrayfb123912009-05-28 18:19:00 +00006136- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
6137
R. David Murray1f1b9d32009-05-27 20:56:59 +00006138- Issue #6121: pydoc now ignores leading and trailing spaces in the

6140
Georg Brandlfaf41492009-05-26 18:31:11 +00006141- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
6142 arguments for strings with a space in them.
6143
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00006144- collections.namedtuple() was not working with the following field
6145 names: cls, self, tuple, itemgetter, and property.
6146
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00006147- In unittest, using a skipping decorator on a class is now equivalent to
6148 skipping every test on the class. The ClassTestSuite class has been removed.
6149
Martin v. Löwis70ccd162009-05-24 19:47:22 +00006150- Issue #6050: Don't fail extracting a directory from a zipfile if
6151 the directory already exists.
6152
Antoine Pitrou61f77b52009-05-24 15:46:13 +00006153- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
6154 than an int, which makes some operations possible under 64-bit Linux (e.g.
6155 DN_MULTISHOT with F_NOTIFY).
6156
Antoine Pitrou716c4442009-05-23 19:04:03 +00006157- Issue #5761: Add the name of the underlying file to the repr() of various
6158 IO objects.
6159
R. David Murraycaa27b72009-05-23 18:49:56 +00006160- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
6161 by Musashi Tamura, tests by Marcin Bachry.
6162
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00006163- Issue #1983: Fix functions taking or returning a process identifier to use
6164 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
6165 a process identifier type wider than the standard C integer type.
6166
R. David Murray87e20742009-05-23 01:30:26 +00006167- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

6178
Antoine Pitroue4501852009-05-14 18:55:55 +00006179- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
6180 library. This means, for example, that opening an UTF-16 text file in
6181 append mode doesn't add a BOM at the end of the file if the file isn't
6182 empty.
6183
R. David Murray74b89242009-05-13 17:33:03 +00006184- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
6185 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
6186 corrects a pydoc regression.
6187
Georg Brandl5f90d792010-08-01 22:31:05 +00006188- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00006189 now it does. This also means getfp method now returns the real fp.

Georg Brandl5f90d792010-08-01 22:31:05 +00006221- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00006222 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Petersonbd35b032009-04-04 23:16:41 +00006227What's New in Python 3.1 beta 1?
6228================================
6229
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00006230*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00006231
6232Core and Builtins
6233-----------------
6234
Mark Dickinson865e01a2009-05-07 16:37:01 +00006235- Issue #5914: Add new C API function PyOS_string_to_double, and
6236 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
6237
Eric Smith741191f2009-05-06 13:08:15 +00006238- Issue #3382: float.__format__, complex.__format__, and %-formatting
6239 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
6240 affects nan -> NAN and inf -> INF.
6241
Mark Hammond5a607a32009-05-06 08:04:54 +00006242- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
6243 in all operations, including splitdrive, split, etc. splitunc() now issues
6244 a PendingDeprecation warning.
6245
Eric Smith63376222009-05-05 14:04:18 +00006246- Issue #5920: For float.__format__, change the behavior with the
6247 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6248 to be like 'g' but with at least one decimal point and with a
6249 default precision of 12. Previously, the behavior the same but with
6250 a default precision of 6. This more closely matches str(), and
6251 reduces surprises when adding alignment flags to the empty
6252 presentation type. This also affects the new complex.__format__ in
6253 the same way.
6254
Martin v. Löwis011e8422009-05-05 04:43:17 +00006255- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
6256
R. David Murrayb18500d2009-05-04 22:59:07 +00006257- Issue #5890: in subclasses of 'property' the __doc__ attribute was
6258 shadowed by classtype's, even if it was None. property now
6259 inserts the __doc__ into the subclass instance __dict__.
6260
Antoine Pitrou244651a2009-05-04 18:56:13 +00006261- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
6262 sequences. Patch by Nick Barnes and Victor Stinner.
6263
Martin v. Löwise0a2b722009-05-10 08:08:56 +00006264- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00006265
Benjamin Petersond2e0c792009-05-01 20:40:59 +00006266- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6267 received a new method, detach(). detach() disconnects the underlying stream
6268 from the buffer or text IO and returns it.
6269
Mark Dickinson33841c32009-05-01 15:37:04 +00006270- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6271 floats with absolute value over 1e50. Also remove length
6272 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6273 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006274
Eric Smith741191f2009-05-06 13:08:15 +00006275- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006276 format(complex(1, 2./3), '.5') now produces a sensible result.
6277
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006278- Issue #5864: Fix empty format code formatting for floats so that it
6279 never gives more than the requested number of significant digits.
6280
Eric Smith6dc46f52009-04-27 20:39:49 +00006281- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6282 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6283
Eric Smithcc32a112009-04-26 21:35:14 +00006284- Issue #5835: Deprecate PyOS_ascii_formatd.
6285
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006286- Issue #4971: Fix titlecase for characters that are their own
6287 titlecase, but not their own uppercase.
6288
Benjamin Peterson193152c2009-04-25 01:08:45 +00006289- Issue #5283: Setting __class__ in __del__ caused a segfault.
6290
Mark Dickinsonad476da2009-04-23 19:14:16 +00006291- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6292 z involves nans, infs or negative zeros.
6293
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006294- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006295
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006296- Issue #1869 (and many duplicates): make round(x, n) correctly
6297 rounded for a float x, by using the decimal <-> binary conversions
6298 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6299 consistently agrees with format(x, '.2f').
6300
Benjamin Petersonae937c02009-04-18 20:54:08 +00006301- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6302 some builtin types.
6303
Eric Smith0923d1d2009-04-16 20:16:10 +00006304- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6305
Eric Smith35e84722009-04-16 20:21:28 +00006306- Issue #5515: str.format() type 'n' combined with commas and leading
6307 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006308
6309- Implement PEP 378, Format Specifier for Thousands Separator, for
6310 floats.
6311
Mark Dickinson3370cce2009-04-17 22:40:53 +00006312- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006313 1e11, not 1e12. This avoids printing 13 significant digits in
6314 situations where only 12 of them are correct. Example problem
6315 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6316 long time.)
6317
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006318- Issue #1580: On most platforms, use a 'short' float repr: for a
6319 finite float x, repr(x) now outputs a string based on the shortest
6320 sequence of decimal digits that rounds to x. Previous behaviour was
6321 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006322 Another minor difference is that the new repr switches to
6323 exponential notation at 1e16 instead of the previous 1e17; this
6324 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006325
6326 There's a new sys attribute sys.float_repr_style, which takes
6327 the value 'short' to indicate that we're using short float repr,
6328 and 'legacy' if the short float repr isn't available for one
6329 reason or another.
6330
6331 The float repr change involves incorporating David Gay's 'perfect
6332 rounding' code into the Python core (it's in Python/dtoa.c). As a
6333 secondary consequence, all string-to-float and float-to-string
6334 conversions (including all float formatting operations) will be
6335 correctly rounded on these platforms.

6341
Georg Brandlabc38772009-04-12 15:51:51 +00006342- The string.maketrans() function is deprecated; there is a new static method
6343 maketrans() on the bytes and bytearray classes. This removes confusion about
6344 the types string.maketrans() is supposed to work with, and mirrors the
6345 methods available on the str class.

Mark Dickinson87ec0852009-02-09 17:15:59 +00006639- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6640 it now forces its argument to double before testing for infinity.
6641
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006642- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Georg Brandl1cdd83c2009-04-05 20:24:29 +00006652- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006653 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00006655- Issue #4707: round(x, n) now returns an integer if x is an integer.
6656 Previously it returned a float.
6657
Antoine Pitroub52ec782009-01-25 16:34:23 +00006658- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6659 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6660 evaluation loop is compiled with a new dispatch mechanism which gives
6661 speedups of up to 20%, depending on the system, on various benchmarks.

Mark Dickinson8055afd2009-01-17 10:04:45 +00006675
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006676- Issue #4935: The overflow checking code in the expandtabs() method common
6677 to str, bytes and bytearray could be optimized away by the compiler, letting
6678 the interpreter segfault instead of raising an error.
6679
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006680- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6681 __next__ method.
6682
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006683- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

Antoine Pitrouab868312009-01-10 15:40:25 +00006691- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6692 common cases are optimized thanks to a dedicated fast path and a moderate
6693 amount of loop unrolling.
6694
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006695- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6696 collecting the oldest generation) so that allocating lots of objects without
6697 destroying them does not show quadratic performance. Based on a proposal by
6698 Martin von Löwis at
6699 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6700
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006701- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006702 having been closed (for instance, a read() call could return some
6703 previously buffered data). Patch by Dmitry Vasiliev.
6704
Antoine Pitrou05608432009-01-09 18:53:14 +00006705- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6706 flag to work properly. Furthermore, when specifying -u, the text stdout
6707 and stderr streams have line-by-line buffering enabled (the default being
6708 to buffer arbitrary chunks of data).
6709
Raymond Hettinger35631532009-01-09 03:58:09 +00006710- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6711 instead of ints (reducing its size from 4 to 8 times thereby reducing
6712 Python's overall memory).
6713
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006714- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6715 an existing .py counterpart, override the co_filename attributes of all
6716 code objects if the original filename is obsolete (which can happen if the
6717 file has been renamed, moved, or if it is accessed through different paths).
6718 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6719
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006720- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6721 one byte. Also fixes the meaning of len() so that it returns the number of
6722 items, rather than the size in bytes.
6723
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006724- Issue #4075: Use OutputDebugStringW in Py_FatalError.

6737
Georg Brandlccc47b62008-12-28 11:44:14 +00006738- Issue #4759: None is now allowed as the first argument of

6740
Skip Montanaro80072cb2008-12-23 03:51:14 +00006741- Added test case to ensure attempts to read from a file opened for writing

6757 failures on OS X.
6758
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006759- Issue #4597: Fixed several opcodes that weren't always propagating

6764
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006765- Issue #4445: Replace "sizeof(PyBytesObject)" with
6766 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6767 bytes instances. On a typical machine this saves 3 bytes of memory
6768 (on average) per allocation of a bytes instance.
6769
Christian Heimesa872de52008-12-05 08:26:55 +00006770- Issue #4533: File read operation was dreadfully slow due to a slowly
6771 growing read buffer. Fixed by using the same growth rate algorithm as
6772 Python 2.x.
6773
Antoine Pitrou5504e892008-12-06 21:27:53 +00006774- Issue #4509: Various issues surrounding resize of bytearray objects to

6776
Georg Brandlf9734072008-12-07 15:30:06 +00006777- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6778 method on file objects with closefd=False. The file descriptor is still
6779 kept open but the file object behaves like a closed file. The ``FileIO``
6780 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00006789- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6790 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6791 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6792 of using the replace error handler in PyUnicode_DecodeUTF8().
