9
10Core and Builtins
11-----------------
12
Victor Stinner5593d8a2010-10-02 11:11:27 +000013- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
14 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE
15 and 32 bits wchar_t (eg. Linux in narrow build).
16
Benjamin Petersonaec5fd12010-10-02 00:03:31 +000017- Issue #10006: type.__abstractmethods__ now raises an AttributeError.
18
Brian Curtin9e88b5a2010-10-01 14:49:24 +000019- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +000020 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +000021
Victor Stinner137c34c2010-09-29 10:25:54 +000022- Issue #9979: Create function PyUnicode_AsWideCharString().
23
Brett Cannon5305a992010-09-27 21:08:38 +000024- Issue #7397: Mention that importlib.import_module() is probably what someone
25 really wants to be using in __import__'s docstring.
26
Brian Curtin1771b542010-09-27 17:56:36 +000027- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions
28 of winreg to use named arguments.
29
Mark Dickinsonb09a3d62010-09-23 20:11:19 +000030- Issue #9930: Remove bogus subtype check that was causing (e.g.)
31 float.__rdiv__(2.0, 3) to return NotImplemented instead of the
32 expected 1.5.
33
Brian Curtine8e4b3b2010-09-23 20:04:14 +000034- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
35
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +000036- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
37 threads are still running. Instead, reinitialize the GIL on a second call to
38 Py_Initialize().
39
Barry Warsaw31c604d2010-09-22 20:58:04 +000040- All SyntaxErrors now have a column offset and therefore a caret when the
41 error is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +000042
Brett Cannonbc2eff32010-09-19 21:39:02 +000043- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
44 module that was imported, but instead gets the module from sys.modules.
45
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +000046- Issue #9212: The range type_items now provides index() and count()
47 methods, to conform to the Sequence ABC. Patch by Daniel Urban and
48 Daniel Stutzbach.
49
Eric Smithe4d63172010-09-13 20:48:43 +000050- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
51 is called with a non-empty format string. This is an effort to
52 future-proof user code. If a derived class does not currently
53 implement __format__ but later adds its own __format__, it would
54 most likely break user code that had supplied a format string. This
55 will be changed to a DeprecationWaring in Python 3.3 and it will be
56 an error in Python 3.4.
57
Antoine Pitrou1df15362010-09-13 14:16:46 +000058- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
59 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
60 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
61
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +000062- Issue #9210: Configure option --with-wctype-functions was removed. Using the
63 functions from the libc caused the methods .upper() and lower() to become
64 locale aware and created subtly wrong results.
65
Victor Stinner1205f272010-09-11 00:54:47 +000066- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on
67 a non-ASCII byte in the format string.
68
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +000069- Issue #4617: Previously it was illegal to delete a name from the local
70 namespace if it occurs as a free variable in a nested block. This limitation
71 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
72
Antoine Pitroue4a18922010-09-09 20:30:23 +000073- Issue #9804: ascii() now always represents unicode surrogate pairs as
74 a single ``\UXXXXXXXX``, regardless of whether the character is printable
75 or not. Also, the "backslashreplace" error handler now joins surrogate
76 pairs into a single character on UCS-2 builds.
77
Antoine Pitrou6e6cc832010-09-09 12:59:39 +000078- Issue #9757: memoryview objects get a release() method to release the
79 underlying buffer (previously this was only done when deallocating the
80 memoryview), and gain support for the context management protocol.
81
Antoine Pitrou079ce542010-09-08 12:37:10 +000082- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
83 thread-local storage key.
84

86-------
87
R. David Murray31e984c2010-10-01 15:40:20 +000088- Issue #10004: quoprimime no longer generates a traceback when confronted
89 with invalid characters after '=' in a Q-encoded word.
90
Senthil Kumaran0f476d42010-09-30 06:09:18 +000091- Issue #1491: BaseHTTPServer nows send a 100 Continue response before sending
92 a 200 OK for the Expect: 100-continue request header.
93
Antoine Pitrou69ab9512010-09-29 15:03:40 +000094- Issue #9360: Cleanup and improvements to the nntplib module. The API
95 now conforms to the philosophy of bytes and unicode separation in Python 3.
96 A test suite has also been added.
97
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +000098- Issue #9962: GzipFile now has the peek() method.
99
Antoine Pitrou3e1fd272010-09-28 21:23:11 +0000100- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
101 retry the select() loop instead of bailing out. This is because select()
102 can incorrectly report a socket as ready for reading (for example, if it
103 received some data with an invalid checksum).
104
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +0000105- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
106
Antoine Pitrou6d7df632010-09-27 17:52:25 +0000107- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
108 received. Now sendall() properly calls signal handlers if necessary,
109 and retries sending if these returned successfully, including on sockets
110 with a timeout.
111
Vinay Sajip9fdd11b2010-09-25 17:48:25 +0000112- Issue #9947: logging: Fixed locking bug in stopListening.
113

117
Brian Curtin0dac8082010-09-23 20:38:14 +0000118- Issue #9790: Rework imports necessary for samefile and sameopenfile
119 in ntpath.
120
Antoine Pitrou70c60442010-09-23 19:51:39 +0000121- Issue #9928: Properly initialize the types exported by the bz2 module.
122
Antoine Pitrou7b969842010-09-23 16:22:51 +0000123- Issue #1675951: Allow GzipFile to work with unseekable file objects.
124 Patch by Florian Festi.
125
Vinay Sajip0637d492010-09-23 08:15:54 +0000126- Logging: Added QueueListener class to facilitate logging usage for
127 performance-critical threads.
128

130
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +0000131- Issue #9877: Expose sysconfig.get_makefile_filename()
132
133- logging: Added hasHandlers() method to Logger and LoggerAdapter.
134
Antoine Pitrou38425292010-09-21 18:19:07 +0000135- Issue #9908: Fix os.stat() on bytes paths under Windows 7.
136
Antoine Pitrou52d42502010-09-21 16:08:27 +0000137- Issue #2643: msync() is not called anymore when deallocating an open mmap
138 object, only munmap().
139
Vinay Sajip212b5902010-09-21 11:31:32 +0000140- logging: Changed LoggerAdapter implementation internally, to make it
141 easier to subclass in a useful way.
142
Vinay Sajipc84f0162010-09-21 11:25:39 +0000143- logging: hasHandlers method was added to Logger, and isEnabledFor,
144 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
145 LoggerAdapter was introduced into the unit tests for logging.
146
Florent Xiclunaeb19dce2010-09-18 23:34:07 +0000147- Issue #1686: Fix string.Template when overriding the pattern attribute.
148
Antoine Pitrou98b46702010-09-18 22:59:00 +0000149- Issue #9854: SocketIO objects now observe the RawIOBase interface in
150 non-blocking mode: they return None when an operation would block (instead
151 of raising an exception).
152
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +0000153- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
154 another kind.
155
Vinay Sajip19ec67a2010-09-17 18:57:36 +0000156- Issue #9441: logging has better coverage for rotating file handlers.
157
Raymond Hettinger35c87f22010-09-16 19:10:17 +0000158- Issue #9865: collections.OrderedDict now has a __sizeof__ method.
159
Antoine Pitrou328ec742010-09-14 18:37:24 +0000160- Issue #9854: The default read() implementation in io.RawIOBase now
161 handles non-blocking readinto() returning None correctly.
162
Antoine Pitrou9e0b8642010-09-14 18:00:02 +0000163- Issue #1552: socket.socketpair() now returns regular socket.socket
164 objects supporting the whole socket API (rather than the "raw"
165 _socket.socket objects).
166
Antoine Pitroua468adc2010-09-14 14:43:44 +0000167- Issue #9853: Fix the signature of SSLSocket.recvfrom() and
168 SSLSocket.sendto() to match the corresponding socket methods.
169
Raymond Hettinger98a5f3f2010-09-13 21:36:00 +0000170- Issue 9840: Added a decorator to reprlib for wrapping __repr__ methods
171 to make them handle recursive calls within the same thread.
172
Vinay Sajipaf9d10a2010-09-13 20:40:30 +0000173- logging: Enhanced HTTPHandler with secure and credentials initializers.
174
Victor Stinnere797c162010-09-17 23:34:26 +0000175- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
Victor Stinnerccb706c2010-09-13 19:41:36 +0000176
Antoine Pitrou6464d5f2010-09-12 14:51:20 +0000177- Issue #9837: The read() method of ZipExtFile objects (as returned by
178 ZipFile.open()) could return more bytes than requested.
179
Raymond Hettingerdc08a142010-09-12 05:15:22 +0000180- Issue #9826: OrderedDict.__repr__ can now handle self-referential
181 values: d['x'] = d.
182
Raymond Hettingerfa11db02010-09-12 04:12:42 +0000183- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
184 it possible for the user to create self-referencing ordered dictionaries
185 which become permanently uncollectable GC garbage. Reinstated the Py3.1
186 approach of using weakref proxies so that reference cycles never get created
187 in the first place.
188
Victor Stinnercb043522010-09-10 23:49:04 +0000189- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
190 encode the value with filesystem encoding and surrogateescape (instead of
Victor Stinner6f7b7832010-09-10 23:50:31 +0000191 utf-8 in strict mode). Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +0000192
Victor Stinner5b519e02010-09-10 21:57:59 +0000193- Issue #9632: Remove sys.setfilesystemencoding() function: use
194 PYTHONFSENCODING environment variable to set the filesystem encoding at
195 Python startup. sys.setfilesystemencoding() creates inconsistencies because
196 it is unable to reencode all filenames in all objects.
197
Antoine Pitrouea99c5c2010-09-09 18:33:21 +0000198- Issue #9410: Various optimizations to the pickle module, leading to
199 speedups up to 4x (depending on the benchmark). Mostly ported from
200 Unladen Swallow; initial patch by Alexandre Vassalotti.
201
Raymond Hettingerbad3c882010-09-09 12:31:00 +0000202- The pprint module now supports printing OrderedDicts in their given
203 order (formerly, it would sort the keys).
204
Vinay Sajip121a1c42010-09-08 10:46:15 +0000205- Logging: Added QueueHandler class to facilitate logging usage with
206 multiprocessing.
207
Antoine Pitrou783eea72010-09-07 22:06:17 +0000208- Issue #9707: Rewritten reference implementation of threading.local which
209 is friendlier towards reference cycles. This change is not normally
210 visible since an optimized C implementation (_thread._local) is used
211 instead.
212
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +0000213- Issue #6394: os.getppid() is now supported on Windows. Note that it will
214 still return the id of the parent process after it has exited. This process
215 id may even have been reused by another unrelated process.
216
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +0000217- Issue #9792: In case of connection failure, socket.create_connection()
218 would swallow the exception and raise a new one, making it impossible
219 to fetch the original errno, or to filter timeout errors. Now the
220 original error is re-raised.
221
Antoine Pitrou5e38aae2010-09-07 16:30:09 +0000222- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
223 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
224 be updated back after the system call. Original patch by Brian Brazil.
225
Raymond Hettinger435cb0f2010-09-06 23:36:31 +0000226- Updates to the random module:
227
228 * Document which parts of the module are guaranteed to stay the same
229 across versions and which parts are subject to change.
230
Raymond Hettingerf763a722010-09-07 00:38:15 +0000231 * Update the seed() method to use all of the bits in a string
Raymond Hettinger05156612010-09-07 04:44:52 +0000232 instead of just the hash value. This makes better use of the
233 seed value and assures the seeding is platform independent.
234 Issue #7889.
235
236 * Improved the random()-->integer algorithm used in choice(),
237 shuffle(), sample(), randrange(), and randint(). Formerly, it
238 used int(n*random()) which has a slight bias whenever n is not
239 a power of two. Issue #9025.
240
241 * Improved documentation of arguments to randrange(). Issue #9379.
Raymond Hettingerf763a722010-09-07 00:38:15 +0000242
Raymond Hettingerf45abc92010-09-06 21:26:09 +0000243- collections.OrderedDict now supports a new method for repositioning
244 keys to either end.
245
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +0000246- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest
247 test cases now also have assertWarns and assertWarnsRegexp methods to
248 check that a given warning type was triggered by the code under test.
249
Antoine Pitrou972ee132010-09-06 18:48:21 +0000250- Issue #5506: BytesIO objects now have a getbuffer() method exporting a
251 view of their contents without duplicating them. The view is both readable
252 and writable.
253
Brian Curtin62857742010-09-06 17:07:27 +0000254- Issue #7566: Implement os.path.sameopenfile for Windows.
255
Antoine Pitrou0d739d72010-09-05 23:01:12 +0000256- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
257 unsupported operation is attempted (for example, writing to a file open
258 only for reading).
259
Gregory P. Smith13b55292010-09-06 08:30:23 +0000260- hashlib has two new constant attributes: algorithms_guaranteed and
261 algorithms_avaiable that respectively list the names of hash algorithms
262 guaranteed to exist in all Python implementations and the names of hash
263 algorithms available in the current process.
264
Brian Quinlanaf38dc52010-09-21 12:28:43 +0000265- A new package ``concurrent.futures`` as defined by PEP 3148.

271
Benjamin Peterson568867a2010-09-11 16:02:03 +0000272- Issue #9834: Don't segfault in PySequence_GetSlice, PySequence_SetSlice, or
273 PySequence_DelSlice when the object doesn't have any mapping operations
274 defined.

376 return characters from the full Unicode range, even on narrow unicode builds
377 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

Victor Stinner47fcb5b2010-08-13 23:59:58 +0000397- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +0000398 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
399 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +0000405- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
406 use PyUnicode_FromFormatV() to format the warning message.

417 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +0000418
419 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
420 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Georg Brandl62069d32010-07-31 08:56:11 +0000754 start byte and the continuation byte(s) are now considered invalid, instead of
755 the number of bytes specified by the start byte. E.g.:

757 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')

759 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +0000802- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
803 TypeError instead of giving a DeprecationWarning when a float is parsed using
804 the 'L' code (for long long). (All other integer codes already raise
805 TypeError in this case.)

814- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +0000815 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000816 like bytearray.

Georg Brandl62069d32010-07-31 08:56:11 +0000818- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no

828 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
829 equal value.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000831- Issue #8748: Fix two issues with comparisons between complex and integer
832 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +0000833 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
834 (2) The comparison raised an OverflowError for large integers, leading to
835 unpredictable exceptions when combining integers and complex objects in sets
836 or dicts.

Victor Stinnerae6265f2010-05-15 16:27:27 +0000848- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
849 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +0000850 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall

859
Victor Stinner0964ee12010-04-30 16:48:45 +0000860- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of

1028 reversed(range(a, b, c)) with large arguments.

1166 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
1167 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00001168 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00001271- The default size of the re module's compiled regular expression cache has been
1272 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00001273 simply clearing the entire cache on overflow to forgetting the least recently
1274 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00001275 applications that use a lot of regular expressions and limits the impact of
1276 the performance hit anytime the cache is exceeded.

1290 defined in datetime with fast C impementation. Python implementation is based
1291 on the original python prototype for the datetime module by Tim Peters with
1292 minor modifications by the PyPy project. The test suite now tests `datetime`
1293 module with and without `_datetime` acceleration using the same test cases.

1531 operation raises multiple signals and more than one of those signals is
1532 trapped, the specification determines the order in which the signals should be

Georg Brandl62069d32010-07-31 08:56:11 +00001690- Issue #2531: Comparison operations between floats and Decimal instances now
1691 return a result based on the numeric values of the operands; previously they

Georg Brandl62069d32010-07-31 08:56:11 +00002192 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
2193 PyPycLoader inherit from this class and provide implementations in relation to
2194 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00002195
Brett Cannon64ef00f2009-07-20 03:19:18 +00002196- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
2197 the documentation said it did even though the code in PyLoader relied on the
2198 abstract method required by ResourceLoader.

2252
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00002253- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00002254 compared to other unix systems. In particular, os.getgroups() does not reflect
2255 any changes made using os.setgroups() but basicly always returns the same
2256 information as the id command. os.getgroups() can now return more than 16
2257 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00002258

Georg Brandl62069d32010-07-31 08:56:11 +00002282- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
2283 Prior to this change, timezone adjustment in utctimetuple() could produce
2284 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
2285 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00002287- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
2288 directive. When the ``%z`` directive is present in the format string, an
2289 aware ``datetime`` object is returned with ``tzinfo`` bound to a
2290 ``datetime.timezone`` instance constructed from the parsed offset. If both
2291 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
2292 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00002294- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00002295 implementing ``datetime.tzinfo`` interface. Instances of the new class,
2296 ``datetime.timezone``, return fixed name and UTC offset from their
2297 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
2298 returns ``None``. A class attribute, ``utc`` contains an instance
2299 representing the UTC timezone. Original patch by Rafe Kaplan.

2316 with an improved 'binary-split' algorithm that uses fewer multiplications and
2317 allows many of the multiplications to be performed using plain C integer
2318 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00002324- Issue #8644: The accuracy of td.total_seconds() has been improved (by
2325 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00002326 the result is now always correctly rounded, and is equivalent to ``td /
2327 timedelta(seconds=1)``.

2336 integer format code, struct.pack first attempts to convert the non-integer
2337 using its __index__ method. If that method is non-existent or raises
2338 TypeError it goes on to try the __int__ method, as described below.

2918 to be like 'g' but with at least one decimal point and with a
2919 default precision of 12. Previously, the behavior the same but with
2920 a default precision of 6. This more closely matches str(), and
2921 reduces surprises when adding alignment flags to the empty
2922 presentation type. This also affects the new complex.__format__ in
2923 the same way.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00002966- Issue #1869 (and many duplicates): make round(x, n) correctly
2967 rounded for a float x, by using the decimal <-> binary conversions
2968 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2969 consistently agrees with format(x, '.2f').
2970
Benjamin Petersonae937c02009-04-18 20:54:08 +00002971- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

2975
Eric Smith35e84722009-04-16 20:21:28 +00002976- Issue #5515: str.format() type 'n' combined with commas and leading
2977 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002978
2979- Implement PEP 378, Format Specifier for Thousands Separator, for
2980 floats.
2981
Mark Dickinson3370cce2009-04-17 22:40:53 +00002982- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002983 1e11, not 1e12. This avoids printing 13 significant digits in
2984 situations where only 12 of them are correct. Example problem
2985 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2986 long time.)
2987
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002988- Issue #1580: On most platforms, use a 'short' float repr: for a
2989 finite float x, repr(x) now outputs a string based on the shortest
2990 sequence of decimal digits that rounds to x. Previous behaviour was
2991 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002992 Another minor difference is that the new repr switches to
2993 exponential notation at 1e16 instead of the previous 1e17; this
2994 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002995
2996 There's a new sys attribute sys.float_repr_style, which takes
2997 the value 'short' to indicate that we're using short float repr,
2998 and 'legacy' if the short float repr isn't available for one
2999 reason or another.
3000
3001 The float repr change involves incorporating David Gay's 'perfect
3002 rounding' code into the Python core (it's in Python/dtoa.c). As a
3003 secondary consequence, all string-to-float and float-to-string
3004 conversions (including all float formatting operations) will be
3005 correctly rounded on these platforms.
3006
Georg Brandl5f90d792010-08-01 22:31:05 +00003007 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003008 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00003010- Issue #5759: float() didn't call __float__ on str subclasses.
3011
Georg Brandlabc38772009-04-12 15:51:51 +00003012- The string.maketrans() function is deprecated; there is a new static method
3013 maketrans() on the bytes and bytearray classes. This removes confusion about
3014 the types string.maketrans() is supposed to work with, and mirrors the
3015 methods available on the str class.
3016
R. David Murraydc6da8a2009-04-09 22:16:43 +00003017- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

3184 untrackable objects are not tracked by the garbage collector. This can
3185 reduce the size of collections and therefore the garbage collection overhead
3186 on long-running programs, depending on their particular use of datatypes.

3251 (typically /dev/zero under Unix) could crash the interpreter.
3252
Benjamin Peterson59406a92009-03-26 17:10:29 +00003253- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

3255
Lars Gustäbel42e00912009-03-22 20:34:29 +00003256- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
3257 forever on incomplete input. That caused tarfile.open() to hang when used
3258 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
3259 partial bzip2 compressed data.

3265 '>' alignment characters.
3266
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00003267- The error detection code in FileIO.close() could fail to reflect the `errno`

3279 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00003280 struct.error instead of returning b'\xff\xff\xff\xff'. The
3281 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
3282 have been removed from the struct module.

3298 used when using str.format() with str, int, and float arguments.
3299
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00003300- Issue #5249: time.strftime returned malformed string when format string
3301 contained non ascii character on windows.
3302
Benjamin Petersonf5b52242009-03-02 23:31:26 +00003303- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
3304 source has already been decoded into str.
3305
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00003306- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
3307 rotating the object pointer by 4 bits to the right.
3308
Mark Dickinson87ec0852009-02-09 17:15:59 +00003309- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
3310 it now forces its argument to double before testing for infinity.
3311
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00003312- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
3313 returns a non-number type.
3314
Benjamin Peterson87618552009-02-08 15:00:52 +00003315- Issue #5182: Removed memoryview.__str__.
3316
Mark Dickinsonc008a172009-02-01 13:59:22 +00003317- Issue #1717: Removed builtin cmp() function, dropped tp_compare
3318 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00003319 the type definition cmpfunc. The tp_compare slot has been renamed
3320 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00003321
Georg Brandl1cdd83c2009-04-05 20:24:29 +00003322- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00003323 were suppressing all exceptions. These include list() and bytearray().
3324
Mark Dickinson1124e712009-01-28 21:25:58 +00003325- Issue #4707: round(x, n) now returns an integer if x is an integer.
3326 Previously it returned a float.
3327
Antoine Pitroub52ec782009-01-25 16:34:23 +00003328- Issue #4753: By enabling a configure option named '--with-computed-gotos'
3329 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
3330 evaluation loop is compiled with a new dispatch mechanism which gives
3331 speedups of up to 20%, depending on the system, on various benchmarks.
3332
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00003333- Issue #4874: Most builtin decoders now reject unicode input.

3339
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00003340- Issue #4838: When a module is deallocated, free the memory backing the
3341 optional module state data.
3342
Mark Dickinson8055afd2009-01-17 10:04:45 +00003343- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003344 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00003345
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00003346- Issue #4935: The overflow checking code in the expandtabs() method common
3347 to str, bytes and bytearray could be optimized away by the compiler, letting
3348 the interpreter segfault instead of raising an error.
3349
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00003350- Issue #3720: Fix a crash when an iterator modifies its class and removes its
3351 __next__ method.
3352
Mark Dickinsone5e298f2009-01-12 20:49:19 +00003353- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
3354 function no longer attempt to call the __long__ slot to convert an object
3355 to an integer. Only the __int__ and __trunc__ slots are examined.
3356
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00003357- Issue #4893: Use NT threading on CE.
3358

3360
Antoine Pitrouab868312009-01-10 15:40:25 +00003361- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
3362 common cases are optimized thanks to a dedicated fast path and a moderate
3363 amount of loop unrolling.
3364
Antoine Pitrou14b78f52009-01-09 22:27:08 +00003365- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
3366 collecting the oldest generation) so that allocating lots of objects without
3367 destroying them does not show quadratic performance. Based on a proposal by
3368 Martin von Löwis at
3369 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
3370
Vinay Sajip6268cbc2009-01-21 00:19:28 +00003371- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00003372 having been closed (for instance, a read() call could return some
3373 previously buffered data). Patch by Dmitry Vasiliev.
3374
Antoine Pitrou05608432009-01-09 18:53:14 +00003375- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
3376 flag to work properly. Furthermore, when specifying -u, the text stdout
3377 and stderr streams have line-by-line buffering enabled (the default being
3378 to buffer arbitrary chunks of data).
3379
Raymond Hettinger35631532009-01-09 03:58:09 +00003380- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
3381 instead of ints (reducing its size from 4 to 8 times thereby reducing
3382 Python's overall memory).
3383
Antoine Pitroud35cbf62009-01-06 19:02:24 +00003384- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
3385 an existing .py counterpart, override the co_filename attributes of all
3386 code objects if the original filename is obsolete (which can happen if the
3387 file has been renamed, moved, or if it is accessed through different paths).
3388 Patch by Ziga Seilnacht and Jean-Paul Calderone.
3389
Antoine Pitrouc3b39242009-01-03 16:59:18 +00003390- Issue #4580: Fix slicing of memoryviews when the item size is greater than
3391 one byte. Also fixes the meaning of len() so that it returns the number of
3392 items, rather than the size in bytes.
3393
Martin v. Löwis5c88d812009-01-02 20:47:48 +00003394- Issue #4075: Use OutputDebugStringW in Py_FatalError.
3395
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00003396- Issue #4747: When the terminal does not use utf-8, executing a script with
3397 non-ascii characters in its name could fail with a "SyntaxError: None" error.
3398
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003399- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
3400 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00003401
Antoine Pitrou7ddda782009-01-01 15:35:33 +00003402- Issue #3680: Reference cycles created through a dict, set or deque iterator
3403 did not get collected.
3404
Nick Coghlanf1f2f682008-12-30 07:29:12 +00003405- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
3406 where the tp_hash and tp_dict slots are both NULL.
3407
Georg Brandlccc47b62008-12-28 11:44:14 +00003408- Issue #4759: None is now allowed as the first argument of
3409 bytearray.translate(). It was always allowed for bytes.translate().
3410
Skip Montanaro80072cb2008-12-23 03:51:14 +00003411- Added test case to ensure attempts to read from a file opened for writing
3412 fail.
3413
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00003414- Issue #3106: Speedup some comparisons (str/str and int/int).

3418
Antoine Pitrou621601a2008-12-17 23:18:19 +00003419- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
3420 print elapsed times, not only when some objects are uncollectable /
3421 unreachable. Original patch by Neil Schemenauer.
3422
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00003423- Issue #3439: Add a bit_length method to int.
3424
Mark Dickinsonda2706b2008-12-11 18:03:03 +00003425- Issue #2173: When getting device encoding, check that return value of
3426 nl_langinfo is not the empty string. This was causing silent build
3427 failures on OS X.
3428
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00003429- Issue #4597: Fixed several opcodes that weren't always propagating
3430 exceptions.
3431
3432- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00003433 context manager returns a value that cannot be converted to a bool.
3434
Mark Dickinsonfd24b322008-12-06 15:33:31 +00003435- Issue #4445: Replace "sizeof(PyBytesObject)" with
3436 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
3437 bytes instances. On a typical machine this saves 3 bytes of memory
3438 (on average) per allocation of a bytes instance.
3439
Christian Heimesa872de52008-12-05 08:26:55 +00003440- Issue #4533: File read operation was dreadfully slow due to a slowly
3441 growing read buffer. Fixed by using the same growth rate algorithm as
3442 Python 2.x.
3443
Antoine Pitrou5504e892008-12-06 21:27:53 +00003444- Issue #4509: Various issues surrounding resize of bytearray objects to
3445 which there are buffer exports (e.g. memoryview instances).
3446
Georg Brandlf9734072008-12-07 15:30:06 +00003447- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
3448 method on file objects with closefd=False. The file descriptor is still
3449 kept open but the file object behaves like a closed file. The ``FileIO``
3450 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00003451
Antoine Pitroubc420402008-12-07 20:14:49 +00003452- Issue #4569: Interpreter crash when mutating a memoryview with an item size
3453 larger than 1.

3458
Walter Dörwaldc1651a02009-05-03 22:55:55 +00003459- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
3460 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3461 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3462 of using the replace error handler in PyUnicode_DecodeUTF8().
