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

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

Ned Deily657b2de2011-06-28 19:51:30 -07001015- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1016 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1017 interpreter process. This could cause failures in non-Distutils subprocesses
1018 and was unreliable since tests or user programs could modify the interpreter
1019 environment after Distutils set it. Instead, have Distutils set the the
1020 deployment target only in the environment of each build subprocess. It is
1021 still possible to globally override the default by setting
1022 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1023 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -07001024 was built. Also, implement the same handling in packaging.

1814 more quickly. The --multiprocess option is now enabled by default, reducing
1815 the amount of time needed to run the tests. "make test" and "make quicktest"
1816 now include some resource-intensive tests, but no longer run the test suite

1827 with the ``-m`` (or ``--match``) option. This works with all test cases
1828 using the unittest module. This is useful with long test suites

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002931 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

3277
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00003278- Issue #10068: Global objects which have reference cycles with their module's
3279 dict are now cleared again. This causes issue #7140 to appear again.
3280
Victor Stinner257d38f2010-10-09 10:12:11 +00003281- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00003282 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00003283
Georg Brandl27a28582010-10-10 09:49:21 +00003284- ast.literal_eval() can now handle negative numbers. It is also a little more
3285 liberal in what it accepts without compromising the safety of the evaluation.
3286 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00003287
Benjamin Peterson970d1882010-10-02 17:55:47 +00003288- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
3289 result metaclasses can now be ABCs (see #9533).
3290
Victor Stinneraef57e32010-10-02 11:50:49 +00003291- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
3292
Victor Stinner5593d8a2010-10-02 11:11:27 +00003293- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00003294 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
3295 32 bits wchar_t (eg. Linux in narrow build).

Victor Stinner137c34c2010-09-29 10:25:54 +00003300- Issue #9979: Create function PyUnicode_AsWideCharString().
3301
Brett Cannon5305a992010-09-27 21:08:38 +00003302- Issue #7397: Mention that importlib.import_module() is probably what someone
3303 really wants to be using in __import__'s docstring.
3304
Georg Brandl27a28582010-10-10 09:49:21 +00003305- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
3306 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00003307
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00003308- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00003309 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00003310
Brian Curtine8e4b3b2010-09-23 20:04:14 +00003311- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
3312
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00003313- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
3314 threads are still running. Instead, reinitialize the GIL on a second call to
3315 Py_Initialize().
3316
Georg Brandl27a28582010-10-10 09:49:21 +00003317- All SyntaxErrors now have a column offset and therefore a caret when the error
3318 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00003319
Brett Cannonbc2eff32010-09-19 21:39:02 +00003320- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3321 module that was imported, but instead gets the module from sys.modules.
3322
Nick Coghlan37ee8502010-12-03 14:26:13 +00003323- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00003324 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00003325
Georg Brandl27a28582010-10-10 09:49:21 +00003326- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3327 with a non-empty format string. This is an effort to future-proof user
3328 code. If a derived class does not currently implement __format__ but later
3329 adds its own __format__, it would most likely break user code that had
3330 supplied a format string. This will be changed to a DeprecationWaring in
3331 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00003332
Antoine Pitrou1df15362010-09-13 14:16:46 +00003333- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3334 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3335 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3336
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003337- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3338 functions from the libc caused the methods .upper() and lower() to become
3339 locale aware and created subtly wrong results.
3340
Georg Brandl27a28582010-10-10 09:49:21 +00003341- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3342 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003343
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003344- Issue #4617: Previously it was illegal to delete a name from the local
3345 namespace if it occurs as a free variable in a nested block. This limitation
3346 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3347
Georg Brandl27a28582010-10-10 09:49:21 +00003348- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3349 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3350 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3351 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00003352
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003353- Issue #9757: memoryview objects get a release() method to release the
3354 underlying buffer (previously this was only done when deallocating the
3355 memoryview), and gain support for the context management protocol.
3356
Antoine Pitrou079ce542010-09-08 12:37:10 +00003357- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3358 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00003374- Issue #4661: email can now parse bytes input and generate either converted
3375 7bit output or bytes output. Email version bumped to 5.1.0.
3376
Antoine Pitrou59fdd672010-10-08 10:37:08 +00003377- Issue #1589: Add ssl.match_hostname(), to help implement server identity

3379
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00003380- Issue #9759: GzipFile now raises ValueError when an operation is attempted

3382
Éric Araujo6108bf52010-10-04 23:52:37 +00003383- Issue #9042: Fix interaction of custom translation classes and caching in
3384 gettext.
3385
Éric Araujoef777bd2010-10-05 00:04:20 +00003386- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003387 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003388 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003389 replacement for old handle_accept() and avoids the user to call accept()
3390 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00003413- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00003414 retry the select() loop instead of bailing out. This is because select() can
3415 incorrectly report a socket as ready for reading (for example, if it received
3416 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00003473- Issue #9854: The default read() implementation in io.RawIOBase now handles
3474 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00003475
Georg Brandl27a28582010-10-10 09:49:21 +00003476- Issue #1552: socket.socketpair() now returns regular socket.socket objects
3477 supporting the whole socket API (rather than the "raw" _socket.socket
3478 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00003479

Éric Araujod8c73c62011-03-21 03:15:22 +01003483- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00003484 them handle recursive calls within the same thread.
Raymond Hettinger98a5f3f2010-09-13 21:36:00 +00003485
Vinay Sajipaf9d10a2010-09-13 20:40:30 +00003486- logging: Enhanced HTTPHandler with secure and credentials initializers.

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00003490- Issue #9837: The read() method of ZipExtFile objects (as returned by
3491 ZipFile.open()) could return more bytes than requested.
3492
Georg Brandl27a28582010-10-10 09:49:21 +00003493- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:

Raymond Hettingerdc08a142010-09-12 05:15:22 +00003495
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003496- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003497 it possible for the user to create self-referencing ordered dictionaries which
3498 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003499 approach of using weakref proxies so that reference cycles never get created
3500 in the first place.
3501
Victor Stinnercb043522010-09-10 23:49:04 +00003502- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
3503 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00003504 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00003505
Georg Brandl27a28582010-10-10 09:49:21 +00003506- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3507 environment variable to set the filesystem encoding at Python startup.
3508 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3509 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003510
Georg Brandl27a28582010-10-10 09:49:21 +00003511- Issue #9410: Various optimizations to the pickle module, leading to speedups
3512 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
3513 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00003514
Georg Brandl27a28582010-10-10 09:49:21 +00003515- The pprint module now supports printing OrderedDicts in their given order
3516 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00003518- Logging: Added QueueHandler class to facilitate logging usage with
3519 multiprocessing.
3520
Georg Brandl27a28582010-10-10 09:49:21 +00003521- Issue #9707: Rewritten reference implementation of threading.local which is
3522 friendlier towards reference cycles. This change is not normally visible
3523 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003524
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003525- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3526 still return the id of the parent process after it has exited. This process
3527 id may even have been reused by another unrelated process.
3528
Georg Brandl27a28582010-10-10 09:49:21 +00003529- Issue #9792: In case of connection failure, socket.create_connection() would
3530 swallow the exception and raise a new one, making it impossible to fetch the
3531 original errno, or to filter timeout errors. Now the original error is
3532 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003534- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3535 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3536 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00003537
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003538- Updates to the random module:
3539
Georg Brandl27a28582010-10-10 09:49:21 +00003540 * Document which parts of the module are guaranteed to stay the same across
3541 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003542
Georg Brandl27a28582010-10-10 09:49:21 +00003543 * Update the seed() method to use all of the bits in a string instead of just
3544 the hash value. This makes better use of the seed value and assures the
3545 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003546
Georg Brandl27a28582010-10-10 09:49:21 +00003547 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3548 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3549 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003550
3551 * Improved documentation of arguments to randrange(). Issue #9379.

3557 cases now also have assertWarns and assertWarnsRegexp methods to check that a
3558 given warning type was triggered by the code under test.

3565
Antoine Pitrou0d739d72010-09-05 23:01:12 +00003566- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00003567 unsupported operation is attempted (for example, writing to a file open only
3568 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00003570- hashlib has two new constant attributes: algorithms_guaranteed and
3571 algorithms_avaiable that respectively list the names of hash algorithms
3572 guaranteed to exist in all Python implementations and the names of hash
3573 algorithms available in the current process.
3574
Brian Quinlanaf38dc52010-09-21 12:28:43 +00003575- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00003665- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
3666 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
3667 bytecode is a bit simplified. Patch by Demur Rumed.

Georg Brandl649971e2010-09-05 17:06:50 +00003678- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3679 now removed, since their effect was inexistent in 3.x (the default encoding is
3680 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00003681
Antoine Pitroub0fa8312010-09-01 15:10:12 +00003682- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

3684
Georg Brandl649971e2010-09-05 17:06:50 +00003685- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
3686 platforms. Previously, it inlined only when using Microsoft Visual C.

Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +00003701- Issue #5127: The C functions that access the Unicode Database now accept and
3702 return characters from the full Unicode range, even on narrow unicode builds
3703 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3704 in Python is that unicodedata.numeric() now returns the correct value for
3705 large code points, and repr() may consider more characters as printable.
3706
Victor Stinner6c00c142010-08-17 23:37:11 +00003707- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
3708 as a unicode object, instead of a byte string. Function needed to support
3709 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
3710 function.
3711
Victor Stinner6961bd62010-08-17 22:26:51 +00003712- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

Georg Brandl62069d32010-07-31 08:56:11 +00004086 start byte and the continuation byte(s) are now considered invalid, instead of
4087 the number of bytes specified by the start byte. E.g.:
4088 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
4089 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
4090 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
4091 returned a single u'\ufffd'.

4135 TypeError instead of giving a DeprecationWarning when a float is parsed using
4136 the 'L' code (for long long). (All other integer codes already raise
4137 TypeError in this case.)

4141 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
4142
Georg Brandl62069d32010-07-31 08:56:11 +00004143- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol

Georg Brandl62069d32010-07-31 08:56:11 +00004147 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004148 like bytearray.
4149
Georg Brandl62069d32010-07-31 08:56:11 +00004150- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no

4159 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
4160 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
4161 equal value.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004163- Issue #8748: Fix two issues with comparisons between complex and integer
4164 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00004165 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
4166 (2) The comparison raised an OverflowError for large integers, leading to
4167 unpredictable exceptions when combining integers and complex objects in sets
4168 or dicts.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00004470- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
4471 variable argument list. `Py_VA_COPY` is equivalent to C99
4472 `va_copy`, but available on all python platforms.
4473
Mark Dickinsone6fc7402010-08-06 18:55:26 +00004474- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
4475 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
4476 "step = -step" when reversing a slice.
4477
Georg Brandl62069d32010-07-31 08:56:11 +00004478- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the
4479 interpreter to set sys.argv without also modifying sys.path. This helps fix

4484 strings in an efficient manner.
4485
Antoine Pitrou8689a102010-04-01 16:53:15 +00004486- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00004487 function declaration, which was kept for backwards compatibility reasons, is
4488 now removed (the macro was introduced in 1997!).
Antoine Pitrou8689a102010-04-01 16:53:15 +00004489
Georg Brandl62069d32010-07-31 08:56:11 +00004490- Issue #7767: New function PyLong_AsLongLongAndOverflow added, analogous to

Georg Brandl62069d32010-07-31 08:56:11 +00004497 PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
4498 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4499 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004500 to match the behaviour of the other integer format codes.
4501
Georg Brandl62069d32010-07-31 08:56:11 +00004502- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.

Georg Brandl62069d32010-07-31 08:56:11 +00004510- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
4511 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
4512 accessing the d_type and d_name members of structures using PyDescr_COMMON.
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +00004513

4525 ``const char *`` as the string is stored beyond the call.
4526
Georg Brandl62069d32010-07-31 08:56:11 +00004527- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4528 allocator will be automatically disabled when running under Valgrind. This
4529 gives improved memory leak detection when running under Valgrind, while taking
4530 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00004605 simply clearing the entire cache on overflow to forgetting the least recently
4606 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004607 applications that use a lot of regular expressions and limits the impact of
4608 the performance hit anytime the cache is exceeded.

4621 module is renamed to `_datetime` and if available, overrides all classes
4622 defined in datetime with fast C impementation. Python implementation is based
4623 on the original python prototype for the datetime module by Tim Peters with
4624 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00004862- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4863 operation raises multiple signals and more than one of those signals is
4864 trapped, the specification determines the order in which the signals should be
4865 handled. In many cases this order wasn't being followed, leading to the wrong

5087 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00005089- subprocess.Popen now has restore_signals and start_new_session features. The
5090 default of restore_signals=True is a new behavior compared to earlier Python
5091 versions. This means that signals such as SIGPIPE are not ignored by default
5092 in subprocesses launched by Python (Issue #1652).

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005585- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005586 compared to other unix systems. In particular, os.getgroups() does not reflect
5587 any changes made using os.setgroups() but basicly always returns the same
5588 information as the id command. os.getgroups() can now return more than 16
5589 groups on MacOSX.

5615 Prior to this change, timezone adjustment in utctimetuple() could produce
5616 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

Georg Brandl62069d32010-07-31 08:56:11 +00005619- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5620 directive. When the ``%z`` directive is present in the format string, an
5621 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5622 ``datetime.timezone`` instance constructed from the parsed offset. If both
5623 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5624 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005626- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005627 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5628 ``datetime.timezone``, return fixed name and UTC offset from their
5629 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5630 returns ``None``. A class attribute, ``utc`` contains an instance
5631 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00005647- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
5648 with an improved 'binary-split' algorithm that uses fewer multiplications and
5649 allows many of the multiplications to be performed using plain C integer
5650 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
5651 arguments.

Mark Dickinson0381e3f2010-05-08 14:35:02 +00005656- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5657 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005658 the result is now always correctly rounded, and is equivalent to ``td /
5659 timedelta(seconds=1)``.

5668 integer format code, struct.pack first attempts to convert the non-integer
5669 using its __index__ method. If that method is non-existent or raises
5670 TypeError it goes on to try the __int__ method, as described below.

6051 are always None now.
6052
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00006053- Issue #6137: The pickle module now translates module names when loading
6054 or dumping pickles with a 2.x-compatible protocol, in order to make data
6055 sharing and migration easier. This behaviour can be disabled using the
6056 new `fix_imports` optional argument.

Eric Smith41669ca2009-05-23 14:23:22 +00006110- Issue #6089: Fixed str.format with certain invalid field specifiers
6111 that would raise SystemError.
6112
Raymond Hettinger2bcde142009-05-29 04:52:27 +00006113- Issue #5982: staticmethod and classmethod now expose the wrapped
6114 function with __func__.
6115
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00006116- Added support for multiple context managers in the same with-statement.
6117 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00006119- Issue #5829: complex("1e500") no longer raises OverflowError. This
6120 makes it consistent with float("1e500") and interpretation of real
6121 and imaginary literals.
6122
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00006123- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00006127- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
6128 (1) inf and nan strings with trailing whitespace were incorrectly
6129 rejected; (2) parsing of strings representing infinities and nans
6130 was locale aware; and (3) the interpretation of fromhex('-nan')
6131 didn't match that of float('-nan').

6142
Georg Brandlfaf41492009-05-26 18:31:11 +00006143- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
6144 arguments for strings with a space in them.
6145
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00006146- collections.namedtuple() was not working with the following field
6147 names: cls, self, tuple, itemgetter, and property.
6148
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00006149- In unittest, using a skipping decorator on a class is now equivalent to
6150 skipping every test on the class. The ClassTestSuite class has been removed.
6151
Martin v. Löwis70ccd162009-05-24 19:47:22 +00006152- Issue #6050: Don't fail extracting a directory from a zipfile if
6153 the directory already exists.
6154
Antoine Pitrou61f77b52009-05-24 15:46:13 +00006155- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
6156 than an int, which makes some operations possible under 64-bit Linux (e.g.
6157 DN_MULTISHOT with F_NOTIFY).
6158
Antoine Pitrou716c4442009-05-23 19:04:03 +00006159- Issue #5761: Add the name of the underlying file to the repr() of various
6160 IO objects.
6161
R. David Murraycaa27b72009-05-23 18:49:56 +00006162- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
6163 by Musashi Tamura, tests by Marcin Bachry.
6164
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00006165- Issue #1983: Fix functions taking or returning a process identifier to use
6166 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
6167 a process identifier type wider than the standard C integer type.
6168
R. David Murray87e20742009-05-23 01:30:26 +00006169- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

6180
Antoine Pitroue4501852009-05-14 18:55:55 +00006181- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
6182 library. This means, for example, that opening an UTF-16 text file in
6183 append mode doesn't add a BOM at the end of the file if the file isn't
6184 empty.
6185
R. David Murray74b89242009-05-13 17:33:03 +00006186- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
6187 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
6188 corrects a pydoc regression.
6189
Georg Brandl5f90d792010-08-01 22:31:05 +00006190- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00006191 now it does. This also means getfp method now returns the real fp.

Georg Brandl5f90d792010-08-01 22:31:05 +00006223- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00006224 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00006232*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00006233
6234Core and Builtins
6235-----------------
6236
Mark Dickinson865e01a2009-05-07 16:37:01 +00006237- Issue #5914: Add new C API function PyOS_string_to_double, and
6238 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
6239
Eric Smith741191f2009-05-06 13:08:15 +00006240- Issue #3382: float.__format__, complex.__format__, and %-formatting
6241 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
6242 affects nan -> NAN and inf -> INF.
6243
Mark Hammond5a607a32009-05-06 08:04:54 +00006244- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
6245 in all operations, including splitdrive, split, etc. splitunc() now issues
6246 a PendingDeprecation warning.
6247
Eric Smith63376222009-05-05 14:04:18 +00006248- Issue #5920: For float.__format__, change the behavior with the
6249 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6250 to be like 'g' but with at least one decimal point and with a
6251 default precision of 12. Previously, the behavior the same but with
6252 a default precision of 6. This more closely matches str(), and
6253 reduces surprises when adding alignment flags to the empty
6254 presentation type. This also affects the new complex.__format__ in
6255 the same way.
6256
Martin v. Löwis011e8422009-05-05 04:43:17 +00006257- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
6258
R. David Murrayb18500d2009-05-04 22:59:07 +00006259- Issue #5890: in subclasses of 'property' the __doc__ attribute was
6260 shadowed by classtype's, even if it was None. property now
6261 inserts the __doc__ into the subclass instance __dict__.
6262
Antoine Pitrou244651a2009-05-04 18:56:13 +00006263- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
6264 sequences. Patch by Nick Barnes and Victor Stinner.
6265
Martin v. Löwise0a2b722009-05-10 08:08:56 +00006266- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00006267
Benjamin Petersond2e0c792009-05-01 20:40:59 +00006268- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6269 received a new method, detach(). detach() disconnects the underlying stream
6270 from the buffer or text IO and returns it.
6271
Mark Dickinson33841c32009-05-01 15:37:04 +00006272- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6273 floats with absolute value over 1e50. Also remove length
6274 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6275 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006276
Eric Smith741191f2009-05-06 13:08:15 +00006277- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006278 format(complex(1, 2./3), '.5') now produces a sensible result.
6279
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006280- Issue #5864: Fix empty format code formatting for floats so that it
6281 never gives more than the requested number of significant digits.
6282
Eric Smith6dc46f52009-04-27 20:39:49 +00006283- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6284 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6285
Eric Smithcc32a112009-04-26 21:35:14 +00006286- Issue #5835: Deprecate PyOS_ascii_formatd.
6287
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006288- Issue #4971: Fix titlecase for characters that are their own
6289 titlecase, but not their own uppercase.
6290
Benjamin Peterson193152c2009-04-25 01:08:45 +00006291- Issue #5283: Setting __class__ in __del__ caused a segfault.
6292
Mark Dickinsonad476da2009-04-23 19:14:16 +00006293- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6294 z involves nans, infs or negative zeros.
6295
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006296- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006297
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006298- Issue #1869 (and many duplicates): make round(x, n) correctly
6299 rounded for a float x, by using the decimal <-> binary conversions
6300 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6301 consistently agrees with format(x, '.2f').
6302
Benjamin Petersonae937c02009-04-18 20:54:08 +00006303- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6304 some builtin types.
6305
Eric Smith0923d1d2009-04-16 20:16:10 +00006306- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6307
Eric Smith35e84722009-04-16 20:21:28 +00006308- Issue #5515: str.format() type 'n' combined with commas and leading
6309 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006310
6311- Implement PEP 378, Format Specifier for Thousands Separator, for
6312 floats.
6313
Mark Dickinson3370cce2009-04-17 22:40:53 +00006314- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006315 1e11, not 1e12. This avoids printing 13 significant digits in
6316 situations where only 12 of them are correct. Example problem
6317 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6318 long time.)
6319
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006320- Issue #1580: On most platforms, use a 'short' float repr: for a
6321 finite float x, repr(x) now outputs a string based on the shortest
6322 sequence of decimal digits that rounds to x. Previous behaviour was
6323 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006324 Another minor difference is that the new repr switches to
6325 exponential notation at 1e16 instead of the previous 1e17; this
6326 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006327
6328 There's a new sys attribute sys.float_repr_style, which takes
6329 the value 'short' to indicate that we're using short float repr,
6330 and 'legacy' if the short float repr isn't available for one
6331 reason or another.
6332
6333 The float repr change involves incorporating David Gay's 'perfect
6334 rounding' code into the Python core (it's in Python/dtoa.c). As a
6335 secondary consequence, all string-to-float and float-to-string
6336 conversions (including all float formatting operations) will be
6337 correctly rounded on these platforms.

6343
Georg Brandlabc38772009-04-12 15:51:51 +00006344- The string.maketrans() function is deprecated; there is a new static method
6345 maketrans() on the bytes and bytearray classes. This removes confusion about
6346 the types string.maketrans() is supposed to work with, and mirrors the
6347 methods available on the str class.

Mark Dickinson87ec0852009-02-09 17:15:59 +00006641- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6642 it now forces its argument to double before testing for infinity.
6643
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006644- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Georg Brandl1cdd83c2009-04-05 20:24:29 +00006654- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006655 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00006657- Issue #4707: round(x, n) now returns an integer if x is an integer.
6658 Previously it returned a float.
6659
Antoine Pitroub52ec782009-01-25 16:34:23 +00006660- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6661 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6662 evaluation loop is compiled with a new dispatch mechanism which gives
6663 speedups of up to 20%, depending on the system, on various benchmarks.

6674
Mark Dickinson8055afd2009-01-17 10:04:45 +00006675- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006676 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006677
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006678- Issue #4935: The overflow checking code in the expandtabs() method common
6679 to str, bytes and bytearray could be optimized away by the compiler, letting
6680 the interpreter segfault instead of raising an error.
6681
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006682- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6683 __next__ method.
6684
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006685- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

6692
Antoine Pitrouab868312009-01-10 15:40:25 +00006693- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6694 common cases are optimized thanks to a dedicated fast path and a moderate
6695 amount of loop unrolling.
6696
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006697- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6698 collecting the oldest generation) so that allocating lots of objects without
6699 destroying them does not show quadratic performance. Based on a proposal by
6700 Martin von Löwis at
6701 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6702
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006703- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006704 having been closed (for instance, a read() call could return some
6705 previously buffered data). Patch by Dmitry Vasiliev.
6706
Antoine Pitrou05608432009-01-09 18:53:14 +00006707- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6708 flag to work properly. Furthermore, when specifying -u, the text stdout
6709 and stderr streams have line-by-line buffering enabled (the default being
6710 to buffer arbitrary chunks of data).
6711
Raymond Hettinger35631532009-01-09 03:58:09 +00006712- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6713 instead of ints (reducing its size from 4 to 8 times thereby reducing
6714 Python's overall memory).
6715
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006716- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6717 an existing .py counterpart, override the co_filename attributes of all
6718 code objects if the original filename is obsolete (which can happen if the
6719 file has been renamed, moved, or if it is accessed through different paths).
6720 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6721
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006722- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6723 one byte. Also fixes the meaning of len() so that it returns the number of
6724 items, rather than the size in bytes.
6725
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006726- Issue #4075: Use OutputDebugStringW in Py_FatalError.

6730
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006731- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

6739
Georg Brandlccc47b62008-12-28 11:44:14 +00006740- Issue #4759: None is now allowed as the first argument of

6742
Skip Montanaro80072cb2008-12-23 03:51:14 +00006743- Added test case to ensure attempts to read from a file opened for writing

6759 failures on OS X.
6760
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006761- Issue #4597: Fixed several opcodes that weren't always propagating

6766
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006767- Issue #4445: Replace "sizeof(PyBytesObject)" with
6768 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6769 bytes instances. On a typical machine this saves 3 bytes of memory
6770 (on average) per allocation of a bytes instance.
6771
Christian Heimesa872de52008-12-05 08:26:55 +00006772- Issue #4533: File read operation was dreadfully slow due to a slowly
6773 growing read buffer. Fixed by using the same growth rate algorithm as
6774 Python 2.x.
6775
Antoine Pitrou5504e892008-12-06 21:27:53 +00006776- Issue #4509: Various issues surrounding resize of bytearray objects to

6778
Georg Brandlf9734072008-12-07 15:30:06 +00006779- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6780 method on file objects with closefd=False. The file descriptor is still
6781 kept open but the file object behaves like a closed file. The ``FileIO``
6782 object also got a new readonly attribute ``closefd``.

6792 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6793 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6794 of using the replace error handler in PyUnicode_DecodeUTF8().
