347 and was unreliable since tests or user programs could modify the interpreter
348 environment after Distutils set it. Instead, have Distutils set the the
349 deployment target only in the environment of each build subprocess. It is
350 still possible to globally override the default by setting
351 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
352 greater or equal to the default value, the value with which the interpreter
353 was built.

1196 is made for all headers in any serialized message at serialization time. This
1197 provides protection against header injection attacks.

1219 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00001850 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001851 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

2193Core and Builtins
2194-----------------
2195
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002196- Issue #10068: Global objects which have reference cycles with their module's
2197 dict are now cleared again. This causes issue #7140 to appear again.
2198
Victor Stinner257d38f2010-10-09 10:12:11 +00002199- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002200 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002201
Georg Brandl27a28582010-10-10 09:49:21 +00002202- ast.literal_eval() can now handle negative numbers. It is also a little more
2203 liberal in what it accepts without compromising the safety of the evaluation.
2204 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002205
Benjamin Peterson970d1882010-10-02 17:55:47 +00002206- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2207 result metaclasses can now be ABCs (see #9533).
2208
Victor Stinneraef57e32010-10-02 11:50:49 +00002209- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2210
Victor Stinner5593d8a2010-10-02 11:11:27 +00002211- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002212 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2213 32 bits wchar_t (eg. Linux in narrow build).

Victor Stinner5593d8a2010-10-02 11:11:27 +00002216 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002217
Victor Stinner137c34c2010-09-29 10:25:54 +00002218- Issue #9979: Create function PyUnicode_AsWideCharString().
2219
Brett Cannon5305a992010-09-27 21:08:38 +00002220- Issue #7397: Mention that importlib.import_module() is probably what someone
2221 really wants to be using in __import__'s docstring.
2222
Georg Brandl27a28582010-10-10 09:49:21 +00002223- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2224 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002225
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002226- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002227 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002228
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002229- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2230
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002231- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2232 threads are still running. Instead, reinitialize the GIL on a second call to
2233 Py_Initialize().
2234
Georg Brandl27a28582010-10-10 09:49:21 +00002235- All SyntaxErrors now have a column offset and therefore a caret when the error
2236 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002237
Brett Cannonbc2eff32010-09-19 21:39:02 +00002238- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2239 module that was imported, but instead gets the module from sys.modules.
2240
Nick Coghlan37ee8502010-12-03 14:26:13 +00002241- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002242 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002243
Georg Brandl27a28582010-10-10 09:49:21 +00002244- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2245 with a non-empty format string. This is an effort to future-proof user
2246 code. If a derived class does not currently implement __format__ but later
2247 adds its own __format__, it would most likely break user code that had
2248 supplied a format string. This will be changed to a DeprecationWaring in
2249 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002250
Antoine Pitrou1df15362010-09-13 14:16:46 +00002251- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2252 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2253 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2254
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002255- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2256 functions from the libc caused the methods .upper() and lower() to become
2257 locale aware and created subtly wrong results.
2258
Georg Brandl27a28582010-10-10 09:49:21 +00002259- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2260 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002261
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002262- Issue #4617: Previously it was illegal to delete a name from the local
2263 namespace if it occurs as a free variable in a nested block. This limitation
2264 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2265
Georg Brandl27a28582010-10-10 09:49:21 +00002266- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2267 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2268 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2269 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002270
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002271- Issue #9757: memoryview objects get a release() method to release the
2272 underlying buffer (previously this was only done when deallocating the
2273 memoryview), and gain support for the context management protocol.
2274
Antoine Pitrou079ce542010-09-08 12:37:10 +00002275- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2276 thread-local storage key.

2288 not in build_clib.
2289
Antoine Pitroudbec7802010-10-10 09:37:12 +00002290- Issue #9437: Fix building C extensions with non-default LDFLAGS.
2291
R. David Murray96fd54e2010-10-08 15:55:28 +00002292- Issue #4661: email can now parse bytes input and generate either converted
2293 7bit output or bytes output. Email version bumped to 5.1.0.
2294
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002295- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2296 verification for higher-level protocols.
2297
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002298- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2299 after the file is closed. Patch by Jeffrey Finkelstein.
2300
Éric Araujo6108bf52010-10-04 23:52:37 +00002301- Issue #9042: Fix interaction of custom translation classes and caching in
2302 gettext.
2303
Éric Araujoef777bd2010-10-05 00:04:20 +00002304- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002305 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002306 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002307 replacement for old handle_accept() and avoids the user to call accept()
2308 directly.
2309
Lars Gustäbel331b8002010-10-04 15:18:47 +00002310- Issue #9065: tarfile no longer uses "root" as the default for the uname and

2314 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002315
R. David Murray5397e862010-10-02 15:58:26 +00002316- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2317 characters that appear inside quoted strings in email addresses.
2318
Georg Brandl27a28582010-10-10 09:49:21 +00002319- Issue #10004: quoprimime no longer generates a traceback when confronted with
2320 invalid characters after '=' in a Q-encoded word.

Georg Brandl27a28582010-10-10 09:49:21 +00002322- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
2323 sending a 200 OK for the Expect: 100-continue request header.

2326 conforms to the philosophy of bytes and unicode separation in Python 3. A
2327 test suite has also been added.

Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002329- Issue #9962: GzipFile now has the peek() method.
2330
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002331- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002332 retry the select() loop instead of bailing out. This is because select() can
2333 incorrectly report a socket as ready for reading (for example, if it received
2334 some data with an invalid checksum).

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002408- Issue #9837: The read() method of ZipExtFile objects (as returned by
2409 ZipFile.open()) could return more bytes than requested.
2410
Georg Brandl27a28582010-10-10 09:49:21 +00002411- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2412 d['x'] = d.

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002414- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002415 it possible for the user to create self-referencing ordered dictionaries which
2416 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002417 approach of using weakref proxies so that reference cycles never get created
2418 in the first place.
2419
Victor Stinnercb043522010-09-10 23:49:04 +00002420- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2421 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002422 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002423
Georg Brandl27a28582010-10-10 09:49:21 +00002424- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2425 environment variable to set the filesystem encoding at Python startup.
2426 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2427 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002428
Georg Brandl27a28582010-10-10 09:49:21 +00002429- Issue #9410: Various optimizations to the pickle module, leading to speedups
2430 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2431 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002432
Georg Brandl27a28582010-10-10 09:49:21 +00002433- The pprint module now supports printing OrderedDicts in their given order
2434 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002435
Vinay Sajip121a1c42010-09-08 10:46:15 +00002436- Logging: Added QueueHandler class to facilitate logging usage with
2437 multiprocessing.
2438
Georg Brandl27a28582010-10-10 09:49:21 +00002439- Issue #9707: Rewritten reference implementation of threading.local which is
2440 friendlier towards reference cycles. This change is not normally visible
2441 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002442
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002443- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2444 still return the id of the parent process after it has exited. This process
2445 id may even have been reused by another unrelated process.
2446
Georg Brandl27a28582010-10-10 09:49:21 +00002447- Issue #9792: In case of connection failure, socket.create_connection() would
2448 swallow the exception and raise a new one, making it impossible to fetch the
2449 original errno, or to filter timeout errors. Now the original error is
2450 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002452- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2453 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2454 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002456- Updates to the random module:
2457
Georg Brandl27a28582010-10-10 09:49:21 +00002458 * Document which parts of the module are guaranteed to stay the same across
2459 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002460
Georg Brandl27a28582010-10-10 09:49:21 +00002461 * Update the seed() method to use all of the bits in a string instead of just
2462 the hash value. This makes better use of the seed value and assures the
2463 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002464
Georg Brandl27a28582010-10-10 09:49:21 +00002465 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2466 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2467 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002468
2469 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00002474- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
2475 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2476 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00002477
Georg Brandl27a28582010-10-10 09:49:21 +00002478- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
2479 their contents without duplicating them. The view is both readable and
2480 writable.

2483
Antoine Pitrou0d739d72010-09-05 23:01:12 +00002484- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002485 unsupported operation is attempted (for example, writing to a file open only
2486 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002488- hashlib has two new constant attributes: algorithms_guaranteed and
2489 algorithms_avaiable that respectively list the names of hash algorithms
2490 guaranteed to exist in all Python implementations and the names of hash
2491 algorithms available in the current process.
2492
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002493- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002583- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2584 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
2585 bytecode is a bit simplified. Patch by Demur Rumed.

Georg Brandl649971e2010-09-05 17:06:50 +00002596- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2597 now removed, since their effect was inexistent in 3.x (the default encoding is
2598 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002599
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002600- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
2601 properly. Patch by Stefan Behnel.
2602
Georg Brandl649971e2010-09-05 17:06:50 +00002603- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
2604 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00002605

2620 return characters from the full Unicode range, even on narrow unicode builds
2621 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2622 in Python is that unicodedata.numeric() now returns the correct value for
2623 large code points, and repr() may consider more characters as printable.
2624
Victor Stinner6c00c142010-08-17 23:37:11 +00002625- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00002634- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
2635 the module file to be executed with the -m command line option.

Victor Stinner47fcb5b2010-08-13 23:59:58 +00002641- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00002642 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2643 objects are output as-is.

2647 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00002648
Georg Brandl649971e2010-09-05 17:06:50 +00002649- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2650 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00002651
Georg Brandl649971e2010-09-05 17:06:50 +00002652- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an

Georg Brandl62069d32010-07-31 08:56:11 +00003004 start byte and the continuation byte(s) are now considered invalid, instead of
3005 the number of bytes specified by the start byte. E.g.:
3006 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3007 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3008 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3009 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003052- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3053 TypeError instead of giving a DeprecationWarning when a float is parsed using
3054 the 'L' code (for long long). (All other integer codes already raise
3055 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003056
Victor Stinner600d3be2010-06-10 12:00:55 +00003057- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to

3059 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3060
Georg Brandl62069d32010-07-31 08:56:11 +00003061- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3062 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003063
3064- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003065 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003066 like bytearray.
3067
Georg Brandl62069d32010-07-31 08:56:11 +00003068- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003069 used anymore and it was never documented.

Georg Brandl62069d32010-07-31 08:56:11 +00003076- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3077 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3078 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3079 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003080
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003081- Issue #8748: Fix two issues with comparisons between complex and integer
3082 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003083 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3084 (2) The comparison raised an OverflowError for large integers, leading to
3085 unpredictable exceptions when combining integers and complex objects in sets
3086 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003087

3090
Victor Stinner9ca9c252010-05-19 16:53:30 +00003091- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003092 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003093 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.

Victor Stinnerae6265f2010-05-15 16:27:27 +00003098- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3099 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003100 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003101 back to UTF-8.

Mark Dickinsone6fc7402010-08-06 18:55:26 +00003392- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3393 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

3416 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3417 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003418 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003428- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3429 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3430 accessing the d_type and d_name members of structures using PyDescr_COMMON.

3447 gives improved memory leak detection when running under Valgrind, while taking
3448 advantage of pymalloc at other times.

3524 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003525 applications that use a lot of regular expressions and limits the impact of
3526 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003823- Issue #8524: When creating an SSL socket, the timeout value of the original
3824 socket wasn't retained (instead, a socket with a positive timeout would be
3825 turned into a non-blocking SSL socket).

Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003827- Issue #5103: SSL handshake would ignore the socket timeout and block
3828 indefinitely if the other end didn't respond.
3829
Georg Brandl62069d32010-07-31 08:56:11 +00003830- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Raymond Hettingerc50846a2010-04-05 18:56:31 +00003924- Add functools.total_ordering() and functools.cmp_to_key().
3925
Georg Brandl62069d32010-07-31 08:56:11 +00003926- Issue #8257: The Decimal construct now accepts a float instance directly,
3927 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00003928
3929 >>> Decimal(1.1)
3930 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00003935- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3936 InvalidOperation instead of returning False. (Comparisons involving a quiet
3937 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3938 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003939
Georg Brandl62069d32010-07-31 08:56:11 +00003940- Issue #2531: Comparison operations between floats and Decimal instances now
3941 return a result based on the numeric values of the operands; previously they
3942 returned an arbitrary result based on the relative ordering of id(float) and
3943 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3944 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003945
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003946- Added a subtract() method to collections.Counter().
3947
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003948- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003949 argument `-` which tells it to read files to compile from stdin. Each line is
3950 read on demand and the named file is compiled immediately. (Original patch by
3951 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00003953- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00003957- Comparisons using one of <, <=, >, >= between a complex instance and a
3958 Fractions instance now raise TypeError instead of returning True/False. This
3959 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3960 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003970 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00004003- The internals of the subprocess module on POSIX systems have been replaced by
4004 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4005 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004006
Georg Brandl62069d32010-07-31 08:56:11 +00004007- subprocess.Popen now has restore_signals and start_new_session features. The
4008 default of restore_signals=True is a new behavior compared to earlier Python
4009 versions. This means that signals such as SIGPIPE are not ignored by default
4010 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004265- Issue #6816: runpy now provides a run_path function that allows Python code to
4266 execute file paths that refer to source or compiled Python files as well as
4267 zipfiles, directories and other valid sys.path entries that contain a
4268 __main__.py file. This allows applications that run other Python scripts to
Nick Coghlan260bd3e2009-11-16 06:49:25 +00004269 support the same flexibility as the CPython command line itself.

Antoine Pitrou434736a2009-11-10 18:46:01 +00004286- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00004287 default when instantiating a `threading.RLock` object. This makes recursive
4288 locks as fast as regular non-recursive locks (previously, they were slower by
4289 10x to 15x).

4309 from stdin so that existing input does not confuse it and lead to incorrect

Georg Brandl62069d32010-07-31 08:56:11 +00004504 compared to other unix systems. In particular, os.getgroups() does not reflect
4505 any changes made using os.setgroups() but basicly always returns the same
4506 information as the id command. os.getgroups() can now return more than 16
4507 groups on MacOSX.

4533 Prior to this change, timezone adjustment in utctimetuple() could produce
4534 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

Georg Brandl62069d32010-07-31 08:56:11 +00004537- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4538 directive. When the ``%z`` directive is present in the format string, an
4539 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4540 ``datetime.timezone`` instance constructed from the parsed offset. If both
4541 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4542 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004544- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004545 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4546 ``datetime.timezone``, return fixed name and UTC offset from their
4547 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4548 returns ``None``. A class attribute, ``utc`` contains an instance
4549 representing the UTC timezone. Original patch by Rafe Kaplan.

4567 allows many of the multiplications to be performed using plain C integer
4568 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Georg Brandl62069d32010-07-31 08:56:11 +00004576 the result is now always correctly rounded, and is equivalent to ``td /

4863 threads could return successfully while some Thread objects were still
4864 referenced. This also introduces a new private function:

4872
R. David Murray0bc11ae2009-10-18 22:18:17 +00004873- Issue #7058: Added save/restore for things like sys.argv and cwd to
Georg Brandl62069d32010-07-31 08:56:11 +00004874 runtest_inner in regrtest, with warnings if the called test modifies them, and

5046 (1) inf and nan strings with trailing whitespace were incorrectly
5047 rejected; (2) parsing of strings representing infinities and nans
5048 was locale aware; and (3) the interpretation of fromhex('-nan')
5049 didn't match that of float('-nan').

5066
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005067- In unittest, using a skipping decorator on a class is now equivalent to

5098
Antoine Pitroue4501852009-05-14 18:55:55 +00005099- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5100 library. This means, for example, that opening an UTF-16 text file in
5101 append mode doesn't add a BOM at the end of the file if the file isn't
5102 empty.

5152Core and Builtins
5153-----------------
5154
Mark Dickinson865e01a2009-05-07 16:37:01 +00005155- Issue #5914: Add new C API function PyOS_string_to_double, and
5156 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5157
Eric Smith741191f2009-05-06 13:08:15 +00005158- Issue #3382: float.__format__, complex.__format__, and %-formatting
5159 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5160 affects nan -> NAN and inf -> INF.
5161
Mark Hammond5a607a32009-05-06 08:04:54 +00005162- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5163 in all operations, including splitdrive, split, etc. splitunc() now issues
5164 a PendingDeprecation warning.
5165
Eric Smith63376222009-05-05 14:04:18 +00005166- Issue #5920: For float.__format__, change the behavior with the
5167 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5168 to be like 'g' but with at least one decimal point and with a
5169 default precision of 12. Previously, the behavior the same but with
5170 a default precision of 6. This more closely matches str(), and
5171 reduces surprises when adding alignment flags to the empty
5172 presentation type. This also affects the new complex.__format__ in
5173 the same way.
5174
Martin v. Löwis011e8422009-05-05 04:43:17 +00005175- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5176
R. David Murrayb18500d2009-05-04 22:59:07 +00005177- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5178 shadowed by classtype's, even if it was None. property now
5179 inserts the __doc__ into the subclass instance __dict__.
5180
Antoine Pitrou244651a2009-05-04 18:56:13 +00005181- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5182 sequences. Patch by Nick Barnes and Victor Stinner.
5183
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005184- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005185
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005186- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5187 received a new method, detach(). detach() disconnects the underlying stream
5188 from the buffer or text IO and returns it.
5189
Mark Dickinson33841c32009-05-01 15:37:04 +00005190- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5191 floats with absolute value over 1e50. Also remove length
5192 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5193 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005194
Eric Smith741191f2009-05-06 13:08:15 +00005195- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005196 format(complex(1, 2./3), '.5') now produces a sensible result.
5197
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005198- Issue #5864: Fix empty format code formatting for floats so that it
5199 never gives more than the requested number of significant digits.
5200
Eric Smith6dc46f52009-04-27 20:39:49 +00005201- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5202 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5203
Eric Smithcc32a112009-04-26 21:35:14 +00005204- Issue #5835: Deprecate PyOS_ascii_formatd.
5205
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005206- Issue #4971: Fix titlecase for characters that are their own
5207 titlecase, but not their own uppercase.
5208
Benjamin Peterson193152c2009-04-25 01:08:45 +00005209- Issue #5283: Setting __class__ in __del__ caused a segfault.
5210
Mark Dickinsonad476da2009-04-23 19:14:16 +00005211- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5212 z involves nans, infs or negative zeros.
5213
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005214- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005215
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005216- Issue #1869 (and many duplicates): make round(x, n) correctly
5217 rounded for a float x, by using the decimal <-> binary conversions
5218 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5219 consistently agrees with format(x, '.2f').
5220
Benjamin Petersonae937c02009-04-18 20:54:08 +00005221- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5222 some builtin types.
5223
Eric Smith0923d1d2009-04-16 20:16:10 +00005224- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5225
Eric Smith35e84722009-04-16 20:21:28 +00005226- Issue #5515: str.format() type 'n' combined with commas and leading
5227 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005228
5229- Implement PEP 378, Format Specifier for Thousands Separator, for
5230 floats.
5231
Mark Dickinson3370cce2009-04-17 22:40:53 +00005232- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005233 1e11, not 1e12. This avoids printing 13 significant digits in
5234 situations where only 12 of them are correct. Example problem
5235 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5236 long time.)
5237
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005238- Issue #1580: On most platforms, use a 'short' float repr: for a
5239 finite float x, repr(x) now outputs a string based on the shortest
5240 sequence of decimal digits that rounds to x. Previous behaviour was
5241 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005242 Another minor difference is that the new repr switches to
5243 exponential notation at 1e16 instead of the previous 1e17; this
5244 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005245
5246 There's a new sys attribute sys.float_repr_style, which takes
5247 the value 'short' to indicate that we're using short float repr,
5248 and 'legacy' if the short float repr isn't available for one
5249 reason or another.
5250
5251 The float repr change involves incorporating David Gay's 'perfect
5252 rounding' code into the Python core (it's in Python/dtoa.c). As a
5253 secondary consequence, all string-to-float and float-to-string
5254 conversions (including all float formatting operations) will be
5255 correctly rounded on these platforms.
5256
Georg Brandl5f90d792010-08-01 22:31:05 +00005257 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005258 this change does not apply.
5259
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005260- Issue #5759: float() didn't call __float__ on str subclasses.
5261
Georg Brandlabc38772009-04-12 15:51:51 +00005262- The string.maketrans() function is deprecated; there is a new static method
5263 maketrans() on the bytes and bytearray classes. This removes confusion about
5264 the types string.maketrans() is supposed to work with, and mirrors the
5265 methods available on the str class.
5266
R. David Murraydc6da8a2009-04-09 22:16:43 +00005267- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5268 its clarity and its speed.
5269
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005270- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005271 to avoid compiler warnings.
5272
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005273- Issue #3739: The unicode-internal encoder now reports the number of characters
5274 consumed like any other encoder (instead of the number of bytes).

Mark Dickinson1124e712009-01-28 21:25:58 +00005575- Issue #4707: round(x, n) now returns an integer if x is an integer.
5576 Previously it returned a float.
5577
Antoine Pitroub52ec782009-01-25 16:34:23 +00005578- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5579 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5580 evaluation loop is compiled with a new dispatch mechanism which gives
5581 speedups of up to 20%, depending on the system, on various benchmarks.
5582
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005583- Issue #4874: Most builtin decoders now reject unicode input.

5591 optional module state data.
5592
Mark Dickinson8055afd2009-01-17 10:04:45 +00005593- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005594 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005595
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005596- Issue #4935: The overflow checking code in the expandtabs() method common
5597 to str, bytes and bytearray could be optimized away by the compiler, letting
5598 the interpreter segfault instead of raising an error.
5599
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005600- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5601 __next__ method.
5602
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005603- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5604 function no longer attempt to call the __long__ slot to convert an object
5605 to an integer. Only the __int__ and __trunc__ slots are examined.

5610
Antoine Pitrouab868312009-01-10 15:40:25 +00005611- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5612 common cases are optimized thanks to a dedicated fast path and a moderate
5613 amount of loop unrolling.
5614
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005615- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5616 collecting the oldest generation) so that allocating lots of objects without
5617 destroying them does not show quadratic performance. Based on a proposal by
5618 Martin von Löwis at
5619 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5620
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005621- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005622 having been closed (for instance, a read() call could return some
5623 previously buffered data). Patch by Dmitry Vasiliev.
5624
Antoine Pitrou05608432009-01-09 18:53:14 +00005625- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5626 flag to work properly. Furthermore, when specifying -u, the text stdout
5627 and stderr streams have line-by-line buffering enabled (the default being
5628 to buffer arbitrary chunks of data).
5629
Raymond Hettinger35631532009-01-09 03:58:09 +00005630- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5631 instead of ints (reducing its size from 4 to 8 times thereby reducing
5632 Python's overall memory).
5633
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005634- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5635 an existing .py counterpart, override the co_filename attributes of all
5636 code objects if the original filename is obsolete (which can happen if the
5637 file has been renamed, moved, or if it is accessed through different paths).
5638 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5639
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005640- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5641 one byte. Also fixes the meaning of len() so that it returns the number of
5642 items, rather than the size in bytes.
5643
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005644- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5645
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005646- Issue #4747: When the terminal does not use utf-8, executing a script with
5647 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5648
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005649- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5653 did not get collected.
5654
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005655- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5656 where the tp_hash and tp_dict slots are both NULL.
5657
Georg Brandlccc47b62008-12-28 11:44:14 +00005658- Issue #4759: None is now allowed as the first argument of
5659 bytearray.translate(). It was always allowed for bytes.translate().
5660
Skip Montanaro80072cb2008-12-23 03:51:14 +00005661- Added test case to ensure attempts to read from a file opened for writing
5662 fail.
5663

5668
Antoine Pitrou621601a2008-12-17 23:18:19 +00005669- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

5674
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005675- Issue #2173: When getting device encoding, check that return value of
5676 nl_langinfo is not the empty string. This was causing silent build
5677 failures on OS X.
5678
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005679- Issue #4597: Fixed several opcodes that weren't always propagating
5680 exceptions.
5681
5682- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005683 context manager returns a value that cannot be converted to a bool.
5684
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005685- Issue #4445: Replace "sizeof(PyBytesObject)" with
5686 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5687 bytes instances. On a typical machine this saves 3 bytes of memory
5688 (on average) per allocation of a bytes instance.
5689
Christian Heimesa872de52008-12-05 08:26:55 +00005690- Issue #4533: File read operation was dreadfully slow due to a slowly
5691 growing read buffer. Fixed by using the same growth rate algorithm as
5692 Python 2.x.
5693
Antoine Pitrou5504e892008-12-06 21:27:53 +00005694- Issue #4509: Various issues surrounding resize of bytearray objects to
5695 which there are buffer exports (e.g. memoryview instances).
5696
Georg Brandlf9734072008-12-07 15:30:06 +00005697- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5698 method on file objects with closefd=False. The file descriptor is still
5699 kept open but the file object behaves like a closed file. The ``FileIO``
5700 object also got a new readonly attribute ``closefd``.

5708
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005709- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5710 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5711 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5712 of using the replace error handler in PyUnicode_DecodeUTF8().
