Victor Stinner257d38f2010-10-09 10:12:11 +000040- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +000041 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +000042
Georg Brandl27a28582010-10-10 09:49:21 +000043- ast.literal_eval() can now handle negative numbers. It is also a little more
44 liberal in what it accepts without compromising the safety of the evaluation.
45 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +000046
Benjamin Peterson970d1882010-10-02 17:55:47 +000047- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
48 result metaclasses can now be ABCs (see #9533).

51
Victor Stinner5593d8a2010-10-02 11:11:27 +000052- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +000053 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
54 32 bits wchar_t (eg. Linux in narrow build).

60
Brett Cannon5305a992010-09-27 21:08:38 +000061- Issue #7397: Mention that importlib.import_module() is probably what someone

63
Georg Brandl27a28582010-10-10 09:49:21 +000064- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
65 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +000066
Mark Dickinsonb09a3d62010-09-23 20:11:19 +000067- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +000068 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +000069
Brian Curtine8e4b3b2010-09-23 20:04:14 +000070- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
71
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +000072- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
73 threads are still running. Instead, reinitialize the GIL on a second call to
74 Py_Initialize().
75
Georg Brandl27a28582010-10-10 09:49:21 +000076- All SyntaxErrors now have a column offset and therefore a caret when the error
77 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +000078
Brett Cannonbc2eff32010-09-19 21:39:02 +000079- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
80 module that was imported, but instead gets the module from sys.modules.
81
Georg Brandl27a28582010-10-10 09:49:21 +000082- Issue #9212: The range type_items now provides index() and count() methods, to
83 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +000084
Georg Brandl27a28582010-10-10 09:49:21 +000085- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
86 with a non-empty format string. This is an effort to future-proof user
87 code. If a derived class does not currently implement __format__ but later
88 adds its own __format__, it would most likely break user code that had
89 supplied a format string. This will be changed to a DeprecationWaring in
90 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +000091
Antoine Pitrou1df15362010-09-13 14:16:46 +000092- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
93 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
94 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
95
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +000096- Issue #9210: Configure option --with-wctype-functions was removed. Using the
97 functions from the libc caused the methods .upper() and lower() to become
98 locale aware and created subtly wrong results.
99
Georg Brandl27a28582010-10-10 09:49:21 +0000100- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
101 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +0000102
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +0000103- Issue #4617: Previously it was illegal to delete a name from the local
104 namespace if it occurs as a free variable in a nested block. This limitation
105 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
106
Georg Brandl27a28582010-10-10 09:49:21 +0000107- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
108 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
109 Also, the "backslashreplace" error handler now joins surrogate pairs into a
110 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +0000111
Antoine Pitrou6e6cc832010-09-09 12:59:39 +0000112- Issue #9757: memoryview objects get a release() method to release the
113 underlying buffer (previously this was only done when deallocating the
114 memoryview), and gain support for the context management protocol.
115
Antoine Pitrou079ce542010-09-08 12:37:10 +0000116- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
117 thread-local storage key.

120-------
121
Antoine Pitroudbec7802010-10-10 09:37:12 +0000122- Issue #9437: Fix building C extensions with non-default LDFLAGS.
123
R. David Murray96fd54e2010-10-08 15:55:28 +0000124- Issue #4661: email can now parse bytes input and generate either converted
125 7bit output or bytes output. Email version bumped to 5.1.0.
126
Antoine Pitrou59fdd672010-10-08 10:37:08 +0000127- Issue #1589: Add ssl.match_hostname(), to help implement server identity
128 verification for higher-level protocols.
129
Antoine Pitrou7980eaa2010-10-06 21:21:18 +0000130- Issue #9759: GzipFile now raises ValueError when an operation is attempted
131 after the file is closed. Patch by Jeffrey Finkelstein.
132
Éric Araujo6108bf52010-10-04 23:52:37 +0000133- Issue #9042: Fix interaction of custom translation classes and caching in
134 gettext.
135
Éric Araujoef777bd2010-10-05 00:04:20 +0000136- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000137 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +0000138 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000139 replacement for old handle_accept() and avoids the user to call accept()
140 directly.
141
Lars Gustäbel331b8002010-10-04 15:18:47 +0000142- Issue #9065: tarfile no longer uses "root" as the default for the uname and
143 gname field.
144
Georg Brandl27a28582010-10-10 09:49:21 +0000145- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
146 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +0000147
R. David Murray5397e862010-10-02 15:58:26 +0000148- Issue #1050268: parseaddr now correctly quotes double quote and backslash
149 characters that appear inside quoted strings in email addresses.
150
Georg Brandl27a28582010-10-10 09:49:21 +0000151- Issue #10004: quoprimime no longer generates a traceback when confronted with
152 invalid characters after '=' in a Q-encoded word.
R. David Murray31e984c2010-10-01 15:40:20 +0000153
Georg Brandl27a28582010-10-10 09:49:21 +0000154- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
155 sending a 200 OK for the Expect: 100-continue request header.
Senthil Kumaran0f476d42010-09-30 06:09:18 +0000156
Georg Brandl27a28582010-10-10 09:49:21 +0000157- Issue #9360: Cleanup and improvements to the nntplib module. The API now
158 conforms to the philosophy of bytes and unicode separation in Python 3. A
159 test suite has also been added.
Antoine Pitrou69ab9512010-09-29 15:03:40 +0000160
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +0000161- Issue #9962: GzipFile now has the peek() method.
162
Antoine Pitrou3e1fd272010-09-28 21:23:11 +0000163- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +0000164 retry the select() loop instead of bailing out. This is because select() can
165 incorrectly report a socket as ready for reading (for example, if it received
166 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +0000167
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +0000168- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
169
Antoine Pitrou6d7df632010-09-27 17:52:25 +0000170- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +0000171 received. Now sendall() properly calls signal handlers if necessary, and
172 retries sending if these returned successfully, including on sockets with a
173 timeout.

207 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
208 LoggerAdapter was introduced into the unit tests for logging.

211
Antoine Pitrou98b46702010-09-18 22:59:00 +0000212- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +0000213 non-blocking mode: they return None when an operation would block (instead of
214 raising an exception).

227 supporting the whole socket API (rather than the "raw" _socket.socket
228 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +0000229
Georg Brandl27a28582010-10-10 09:49:21 +0000230- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()

Raymond Hettingerfa11db02010-09-12 04:12:42 +0000246- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +0000247 it possible for the user to create self-referencing ordered dictionaries which
248 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +0000249 approach of using weakref proxies so that reference cycles never get created
250 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +0000261- Issue #9410: Various optimizations to the pickle module, leading to speedups
262 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
263 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +0000264
Georg Brandl27a28582010-10-10 09:49:21 +0000265- The pprint module now supports printing OrderedDicts in their given order
266 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +0000267
Vinay Sajip121a1c42010-09-08 10:46:15 +0000268- Logging: Added QueueHandler class to facilitate logging usage with
269 multiprocessing.

Georg Brandl27a28582010-10-10 09:49:21 +0000271- Issue #9707: Rewritten reference implementation of threading.local which is
272 friendlier towards reference cycles. This change is not normally visible
273 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +0000274
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +0000275- Issue #6394: os.getppid() is now supported on Windows. Note that it will
276 still return the id of the parent process after it has exited. This process
277 id may even have been reused by another unrelated process.
278
Georg Brandl27a28582010-10-10 09:49:21 +0000279- Issue #9792: In case of connection failure, socket.create_connection() would
280 swallow the exception and raise a new one, making it impossible to fetch the
281 original errno, or to filter timeout errors. Now the original error is
282 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +0000284- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
285 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
286 back after the system call. Original patch by Brian Brazil.

Georg Brandl27a28582010-10-10 09:49:21 +0000293 * Update the seed() method to use all of the bits in a string instead of just
294 the hash value. This makes better use of the seed value and assures the
295 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +0000297 * Improved the random()-->integer algorithm used in choice(), shuffle(),
298 sample(), randrange(), and randint(). Formerly, it used int(n*random())
299 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +0000300
301 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +0000306- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
307 cases now also have assertWarns and assertWarnsRegexp methods to check that a
308 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +0000309
Georg Brandl27a28582010-10-10 09:49:21 +0000310- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of

315
Antoine Pitrou0d739d72010-09-05 23:01:12 +0000316- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +0000317 unsupported operation is attempted (for example, writing to a file open only
318 for reading).
Antoine Pitrou0d739d72010-09-05 23:01:12 +0000319
Gregory P. Smith13b55292010-09-06 08:30:23 +0000320- hashlib has two new constant attributes: algorithms_guaranteed and
321 algorithms_avaiable that respectively list the names of hash algorithms
322 guaranteed to exist in all Python implementations and the names of hash
323 algorithms available in the current process.
324
Brian Quinlanaf38dc52010-09-21 12:28:43 +0000325- A new package ``concurrent.futures`` as defined by PEP 3148.

449 return characters from the full Unicode range, even on narrow unicode builds
450 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
451 in Python is that unicodedata.numeric() now returns the correct value for

Victor Stinner47fcb5b2010-08-13 23:59:58 +0000470- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +0000471 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
472 objects are output as-is.

487 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +0000488
Georg Brandl649971e2010-09-05 17:06:50 +0000489- Issue #9416: Fix some issues with complex formatting where the output with no
490 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +0000491
492 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
493 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Victor Stinner8182b712010-07-28 00:40:58 +0000819- Issue #8991: convertbuffer() rejects discontigious buffers.
820
Antoine Pitrou1ac745b2010-07-11 12:12:00 +0000821- Issue #7616: Fix copying of overlapping memoryview slices with the Intel

825
Ezio Melotti57221d02010-07-01 07:32:02 +0000826- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +0000827 start byte and the continuation byte(s) are now considered invalid, instead of
828 the number of bytes specified by the start byte. E.g.:
829 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
830 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
831 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
832 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +0000834- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
835 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

847 dealing with unary minus applied to a constant. The removed code was mutating
848 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +0000849
Victor Stinner554f3f02010-06-16 23:33:54 +0000850- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +0000851 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +0000852 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +0000853 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +0000854
Victor Stinner25e8ec42010-06-25 00:02:38 +0000855- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
856 "w*" format instead. Add tests for "w*" format.
857
Victor Stinner06e49dd2010-06-13 18:21:50 +0000858- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +0000859 formats if the string contains a null byte/character. Write unit tests for

861
Georg Brandl62069d32010-07-31 08:56:11 +0000862- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +0000863 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
864 location of the raised exception.
865
Victor Stinner313a1202010-06-11 23:56:51 +0000866- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
867 filenames and enable os.fsencode().
868
Benjamin Peterson285a6892010-06-22 19:21:52 +0000869- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
870
Georg Brandl62069d32010-07-31 08:56:11 +0000871- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
872 interpreter with characters outside the Basic Multilingual Plane (higher than
873 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +0000874
Georg Brandl62069d32010-07-31 08:56:11 +0000875- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
876 TypeError instead of giving a DeprecationWarning when a float is parsed using
877 the 'L' code (for long long). (All other integer codes already raise
878 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +0000879
Victor Stinner600d3be2010-06-10 12:00:55 +0000880- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
881 enable shortcuts for upper case encoding name. Add also a shortcut for
882 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
883
Georg Brandl62069d32010-07-31 08:56:11 +0000884- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
885 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000886
887- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +0000888 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000889 like bytearray.
890
Georg Brandl62069d32010-07-31 08:56:11 +0000891- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +0000892 used anymore and it was never documented.
893
Georg Brandl62069d32010-07-31 08:56:11 +0000894- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +0000896- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
897 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +0000898
Georg Brandl62069d32010-07-31 08:56:11 +0000899- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
900 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
901 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
902 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +0000903
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000904- Issue #8748: Fix two issues with comparisons between complex and integer
905 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +0000906 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
907 (2) The comparison raised an OverflowError for large integers, leading to
908 unpredictable exceptions when combining integers and complex objects in sets
909 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000910
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000911- Issue #8766: Initialize _warnings module before importing the first module.

913
Victor Stinner9ca9c252010-05-19 16:53:30 +0000914- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +0000915 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +0000916 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +0000917
Georg Brandl62069d32010-07-31 08:56:11 +0000918- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
919 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +0000920
Victor Stinnerae6265f2010-05-15 16:27:27 +0000921- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
922 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +0000923 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000924 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000925
Victor Stinner59e62db2010-05-15 13:14:32 +0000926- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +0000927 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +0000928
Victor Stinnerb744ba12010-05-15 12:27:16 +0000929- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +0000930 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +0000931 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
932
Victor Stinner0964ee12010-04-30 16:48:45 +0000933- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +0000934 PyUnicode_FromString() to support surrogates in the filename and use the right
935 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +0000936
Georg Brandl8569e582010-05-19 20:57:08 +0000937- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
938
Georg Brandl62069d32010-07-31 08:56:11 +0000939- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000940
Benjamin Petersonfb886362010-04-24 18:21:17 +0000941- Issue #8419: Prevent the dict constructor from accepting non-string keyword
942 arguments.
943
Victor Stinner14284c22010-04-23 12:02:30 +0000944- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +0000945 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Georg Brandl62069d32010-07-31 08:56:11 +0000955 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

Mark Dickinsone6fc7402010-08-06 18:55:26 +00001215- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
1216 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

Antoine Pitrou3060c452010-08-13 16:27:38 +00001346 simply clearing the entire cache on overflow to forgetting the least recently
1347 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00001348 applications that use a lot of regular expressions and limits the impact of
1349 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00001758- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1759 InvalidOperation instead of returning False. (Comparisons involving a quiet
1760 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1761 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00001763- Issue #2531: Comparison operations between floats and Decimal instances now
1764 return a result based on the numeric values of the operands; previously they
1765 returned an arbitrary result based on the relative ordering of id(float) and
1766 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
1767 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00001768
Raymond Hettinger9c01e442010-04-03 10:32:58 +00001769- Added a subtract() method to collections.Counter().
1770
Barry Warsawd5f9bf52010-03-31 21:36:22 +00001771- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00001772 argument `-` which tells it to read files to compile from stdin. Each line is
1773 read on demand and the named file is compiled immediately. (Original patch by
1774 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00001776- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00001780- Comparisons using one of <, <=, >, >= between a complex instance and a
1781 Fractions instance now raise TypeError instead of returning True/False. This
1782 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1783 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00001826- The internals of the subprocess module on POSIX systems have been replaced by
1827 an extension module (_posixsubprocess) so that the fork()+exec() can be done
1828 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00001829
Georg Brandl62069d32010-07-31 08:56:11 +00001830- subprocess.Popen now has restore_signals and start_new_session features. The
1831 default of restore_signals=True is a new behavior compared to earlier Python
1832 versions. This means that signals such as SIGPIPE are not ignored by default
1833 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00001919- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
1920 position when calling `truncate()`. It would previously change the file
1921 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00001922 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00001924- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00001925 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
1926 archive. The new implementation is significantly faster and can be wrapped in
1927 a :class:`io.BufferedReader` object for more speedups. It also solves an
1928 issue where interleaved calls to `read()` and `readline()` give wrong results.
1929 Patch by Nir Aides.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00002326- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00002327 compared to other unix systems. In particular, os.getgroups() does not reflect

2686 threads could return successfully while some Thread objects were still

2889
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00002890- In unittest, using a skipping decorator on a class is now equivalent to
2891 skipping every test on the class. The ClassTestSuite class has been removed.
2892
Martin v. Löwis70ccd162009-05-24 19:47:22 +00002893- Issue #6050: Don't fail extracting a directory from a zipfile if

2895
Antoine Pitrou61f77b52009-05-24 15:46:13 +00002896- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
2897 than an int, which makes some operations possible under 64-bit Linux (e.g.
2898 DN_MULTISHOT with F_NOTIFY).
2899
Antoine Pitrou716c4442009-05-23 19:04:03 +00002900- Issue #5761: Add the name of the underlying file to the repr() of various

2921
Antoine Pitroue4501852009-05-14 18:55:55 +00002922- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
2923 library. This means, for example, that opening an UTF-16 text file in
2924 append mode doesn't add a BOM at the end of the file if the file isn't
2925 empty.
2926
R. David Murray74b89242009-05-13 17:33:03 +00002927- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
2928 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
2929 corrects a pydoc regression.
2930
Georg Brandl5f90d792010-08-01 22:31:05 +00002931- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00002932 now it does. This also means getfp method now returns the real fp.

2975Core and Builtins
2976-----------------
2977
Mark Dickinson865e01a2009-05-07 16:37:01 +00002978- Issue #5914: Add new C API function PyOS_string_to_double, and
2979 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2980
Eric Smith741191f2009-05-06 13:08:15 +00002981- Issue #3382: float.__format__, complex.__format__, and %-formatting
2982 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2983 affects nan -> NAN and inf -> INF.
2984
Mark Hammond5a607a32009-05-06 08:04:54 +00002985- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2986 in all operations, including splitdrive, split, etc. splitunc() now issues
2987 a PendingDeprecation warning.
2988
Eric Smith63376222009-05-05 14:04:18 +00002989- Issue #5920: For float.__format__, change the behavior with the
2990 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2991 to be like 'g' but with at least one decimal point and with a
2992 default precision of 12. Previously, the behavior the same but with
2993 a default precision of 6. This more closely matches str(), and
2994 reduces surprises when adding alignment flags to the empty
2995 presentation type. This also affects the new complex.__format__ in
2996 the same way.
2997
Martin v. Löwis011e8422009-05-05 04:43:17 +00002998- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2999
R. David Murrayb18500d2009-05-04 22:59:07 +00003000- Issue #5890: in subclasses of 'property' the __doc__ attribute was
3001 shadowed by classtype's, even if it was None. property now
3002 inserts the __doc__ into the subclass instance __dict__.
3003
Antoine Pitrou244651a2009-05-04 18:56:13 +00003004- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
3005 sequences. Patch by Nick Barnes and Victor Stinner.
3006
Martin v. Löwise0a2b722009-05-10 08:08:56 +00003007- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00003008
Benjamin Petersond2e0c792009-05-01 20:40:59 +00003009- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
3010 received a new method, detach(). detach() disconnects the underlying stream
3011 from the buffer or text IO and returns it.
3012
Mark Dickinson33841c32009-05-01 15:37:04 +00003013- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
3014 floats with absolute value over 1e50. Also remove length
3015 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
3016 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00003017
Eric Smith741191f2009-05-06 13:08:15 +00003018- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00003019 format(complex(1, 2./3), '.5') now produces a sensible result.
3020
Mark Dickinsond3ca5572009-04-29 18:47:07 +00003021- Issue #5864: Fix empty format code formatting for floats so that it
3022 never gives more than the requested number of significant digits.
3023
Eric Smith6dc46f52009-04-27 20:39:49 +00003024- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
3025 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
3026
Eric Smithcc32a112009-04-26 21:35:14 +00003027- Issue #5835: Deprecate PyOS_ascii_formatd.
3028
Martin v. Löwis71efeb72009-04-26 01:02:07 +00003029- Issue #4971: Fix titlecase for characters that are their own
3030 titlecase, but not their own uppercase.
3031
Benjamin Peterson193152c2009-04-25 01:08:45 +00003032- Issue #5283: Setting __class__ in __del__ caused a segfault.
3033
Mark Dickinsonad476da2009-04-23 19:14:16 +00003034- Issue #5816: complex(repr(z)) now recovers z exactly, even when
3035 z involves nans, infs or negative zeros.
3036
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00003037- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00003038
Mark Dickinsone6a076d2009-04-18 11:48:33 +00003039- Issue #1869 (and many duplicates): make round(x, n) correctly
3040 rounded for a float x, by using the decimal <-> binary conversions
3041 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
3042 consistently agrees with format(x, '.2f').
3043
Benjamin Petersonae937c02009-04-18 20:54:08 +00003044- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
3045 some builtin types.
3046
Eric Smith0923d1d2009-04-16 20:16:10 +00003047- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
3048
Eric Smith35e84722009-04-16 20:21:28 +00003049- Issue #5515: str.format() type 'n' combined with commas and leading
3050 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00003051
3052- Implement PEP 378, Format Specifier for Thousands Separator, for
3053 floats.
3054
Mark Dickinson3370cce2009-04-17 22:40:53 +00003055- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003056 1e11, not 1e12. This avoids printing 13 significant digits in
3057 situations where only 12 of them are correct. Example problem
3058 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
3059 long time.)
3060
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003061- Issue #1580: On most platforms, use a 'short' float repr: for a
3062 finite float x, repr(x) now outputs a string based on the shortest
3063 sequence of decimal digits that rounds to x. Previous behaviour was
3064 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00003065 Another minor difference is that the new repr switches to
3066 exponential notation at 1e16 instead of the previous 1e17; this
3067 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003068
3069 There's a new sys attribute sys.float_repr_style, which takes
3070 the value 'short' to indicate that we're using short float repr,
3071 and 'legacy' if the short float repr isn't available for one
3072 reason or another.
3073
3074 The float repr change involves incorporating David Gay's 'perfect
3075 rounding' code into the Python core (it's in Python/dtoa.c). As a
3076 secondary consequence, all string-to-float and float-to-string
3077 conversions (including all float formatting operations) will be
3078 correctly rounded on these platforms.
3079
Georg Brandl5f90d792010-08-01 22:31:05 +00003080 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003081 this change does not apply.
3082
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00003083- Issue #5759: float() didn't call __float__ on str subclasses.
3084
Georg Brandlabc38772009-04-12 15:51:51 +00003085- The string.maketrans() function is deprecated; there is a new static method
3086 maketrans() on the bytes and bytearray classes. This removes confusion about
3087 the types string.maketrans() is supposed to work with, and mirrors the
3088 methods available on the str class.
3089
R. David Murraydc6da8a2009-04-09 22:16:43 +00003090- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
3091 its clarity and its speed.
3092
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003093- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00003094 to avoid compiler warnings.
3095
Walter Dörwald8dc33d52009-05-06 14:41:26 +00003096- Issue #3739: The unicode-internal encoder now reports the number of characters
3097 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +00003177- Issue #1161031: fix readwrite select flag handling: POLLPRI now
3178 results in a handle_expt_event call, not handle_read_event, and POLLERR
3179 and POLLNVAL now call handle_close, not handle_expt_event. Also,
3180 dispatcher now has an 'ignore_log_types' attribute for suppressing
3181 log messages, which is set to 'warning' by default.

3255
Antoine Pitrou3a652b12009-03-23 18:52:06 +00003256- Issue #4688: Add a heuristic so that tuples and dicts containing only
3257 untrackable objects are not tracked by the garbage collector. This can
3258 reduce the size of collections and therefore the garbage collection overhead
3259 on long-running programs, depending on their particular use of datatypes.

3274 and sizeof(Py_UNICODE) == 2.
3275
Eric Smith8ec90442009-03-14 12:29:34 +00003276- Issue #5237: Allow auto-numbered fields in str.format(). For

Lars Gustäbel42e00912009-03-22 20:34:29 +00003329- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
3330 forever on incomplete input. That caused tarfile.open() to hang when used
3331 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
3332 partial bzip2 compressed data.
3333
Mark Dickinson79f52032009-03-17 23:12:51 +00003334- Issue #2110: Add support for thousands separator and 'n' type

Antoine Pitrou8043cf82009-01-09 19:54:29 +00003445 having been closed (for instance, a read() call could return some
3446 previously buffered data). Patch by Dmitry Vasiliev.
3447
Antoine Pitrou05608432009-01-09 18:53:14 +00003448- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
3449 flag to work properly. Furthermore, when specifying -u, the text stdout
3450 and stderr streams have line-by-line buffering enabled (the default being
3451 to buffer arbitrary chunks of data).
3452
Raymond Hettinger35631532009-01-09 03:58:09 +00003453- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
3454 instead of ints (reducing its size from 4 to 8 times thereby reducing
3455 Python's overall memory).
3456
Antoine Pitroud35cbf62009-01-06 19:02:24 +00003457- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
3458 an existing .py counterpart, override the co_filename attributes of all
3459 code objects if the original filename is obsolete (which can happen if the
3460 file has been renamed, moved, or if it is accessed through different paths).

3465 items, rather than the size in bytes.
3466

3497
Mark Dickinsonda2706b2008-12-11 18:03:03 +00003498- Issue #2173: When getting device encoding, check that return value of

3509 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

3512
Christian Heimesa872de52008-12-05 08:26:55 +00003513- Issue #4533: File read operation was dreadfully slow due to a slowly

3515 Python 2.x.
3516
Antoine Pitrou5504e892008-12-06 21:27:53 +00003517- Issue #4509: Various issues surrounding resize of bytearray objects to

Georg Brandlf9734072008-12-07 15:30:06 +00003520- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
3521 method on file objects with closefd=False. The file descriptor is still
3522 kept open but the file object behaves like a closed file. The ``FileIO``
3523 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00003524

3533 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3534 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3535 of using the replace error handler in PyUnicode_DecodeUTF8().

3854
Antoine Pitrou08838b62009-01-21 00:55:13 +00003855- Issue #5008: When a file is opened in append mode with the new IO library,
3856 do an explicit seek to the end of file (so that e.g. tell() returns the
3857 file size rather than 0). This is consistent with the behaviour of the

3888 appropriately when it is being used via socket.makefile() objects
3889 rather than delaying the close by waiting for garbage collection to do it.
3890
Raymond Hettingerb8baf632009-01-14 02:20:07 +00003891- Issue #1696199: Add collections.Counter() for rapid and convenient
