Georg Brandl255abdd2011-01-16 14:17:26 +00001287 continuation line in the formatted value has no leading white space and looks
1288 like a header. Since Generator uses Header to format all headers, this check
1289 is made for all headers in any serialized message at serialization time. This
1290 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001291

Georg Brandl255abdd2011-01-16 14:17:26 +00001300 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001301
Éric Araujof0ab5d62011-05-29 03:43:59 +02001302- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001303 rfc2047-encoding header values with embedded newlines, leaving them without
1304 folding whitespace. It now uses the continuation_ws, as it does for
1305 continuation lines that it creates itself.

1308 time.asctime(), time.ctime() and time.strftime() functions will now format

1310 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1311 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1312 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Antoine Pitroucf9f9802010-11-10 13:55:25 +00001920- Issue #10372: Import the warnings module only after the IO library is
1921 initialized, so as to avoid bootstrap issues with the '-W' option.
1922
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001923- Issue #10293: Remove obsolete field in the PyMemoryView structure, unused
1924 undocumented value PyBUF_SHADOW, and strangely-looking code in

Eric Smith27bbca62010-11-04 17:06:58 +00001928
Benjamin Petersonbbb04122010-10-30 23:16:28 +00001929- If FileIO.__init__ fails, close the file descriptor.
1930
Raymond Hettingerdd421542010-10-30 08:10:29 +00001931- Issue #10221: dict.pop(k) now has a key error message that includes the
1932 missing key (same message d[k] returns for missing keys).
1933
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001934- Issue #5437: A preallocated MemoryError instance should not keep traceback

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001943- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
1944 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001945 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001946 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001947 encoding and to encode command line arguments on this OS.
1948

1950 filenames encoded to the filesystem encoding with the surrogateescape error
Victor Stinner4c7c8c32010-10-16 13:14:10 +00001951 handler (to support undecodable bytes), instead of UTF-8 in strict mode.
1952
Benjamin Peterson230b2062010-10-16 03:45:45 +00001953- Issue #9997: Don't let the name "top" have special significance in scope
1954 resolution.
1955
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001956- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding its value as
1957 the default 512 when compiling on AIX.
R. David Murraye16cda92010-10-15 23:12:57 +00001958

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001999 unexpectedly if the return value of a task could not be pickled. Only the
2000 ``repr`` of such errors are now sent back, wrapped in an

2002
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002003- Issue #9244: The ``apply_async()`` and ``map_async()`` methods of

2340 with a non-empty format string. This is an effort to future-proof user
2341 code. If a derived class does not currently implement __format__ but later
2342 adds its own __format__, it would most likely break user code that had
2343 supplied a format string. This will be changed to a DeprecationWaring in
2344 Python 3.3 and it will be an error in Python 3.4.

2348 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002357- Issue #4617: Previously it was illegal to delete a name from the local
2358 namespace if it occurs as a free variable in a nested block. This limitation
2359 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2360
Georg Brandl27a28582010-10-10 09:49:21 +00002361- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2362 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2363 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2364 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002399- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002400 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002401 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002402 replacement for old handle_accept() and avoids the user to call accept()
2403 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002426- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002427 retry the select() loop instead of bailing out. This is because select() can
2428 incorrectly report a socket as ready for reading (for example, if it received
2429 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002476 non-blocking mode: they return None when an operation would block (instead of

Georg Brandl27a28582010-10-10 09:49:21 +00002489- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2490 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002509- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002510 it possible for the user to create self-referencing ordered dictionaries which
2511 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002512 approach of using weakref proxies so that reference cycles never get created
2513 in the first place.
2514
Victor Stinnercb043522010-09-10 23:49:04 +00002515- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2516 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002517 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002518
Georg Brandl27a28582010-10-10 09:49:21 +00002519- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2520 environment variable to set the filesystem encoding at Python startup.
2521 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2522 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002523
Georg Brandl27a28582010-10-10 09:49:21 +00002524- Issue #9410: Various optimizations to the pickle module, leading to speedups

Georg Brandl27a28582010-10-10 09:49:21 +00002528- The pprint module now supports printing OrderedDicts in their given order

Vinay Sajip121a1c42010-09-08 10:46:15 +00002531- Logging: Added QueueHandler class to facilitate logging usage with
2532 multiprocessing.
2533
Georg Brandl27a28582010-10-10 09:49:21 +00002534- Issue #9707: Rewritten reference implementation of threading.local which is
2535 friendlier towards reference cycles. This change is not normally visible
2536 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002537
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002538- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2539 still return the id of the parent process after it has exited. This process
2540 id may even have been reused by another unrelated process.
2541
Georg Brandl27a28582010-10-10 09:49:21 +00002542- Issue #9792: In case of connection failure, socket.create_connection() would
2543 swallow the exception and raise a new one, making it impossible to fetch the
2544 original errno, or to filter timeout errors. Now the original error is
2545 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002547- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2548 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2549 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002551- Updates to the random module:
2552
Georg Brandl27a28582010-10-10 09:49:21 +00002553 * Document which parts of the module are guaranteed to stay the same across
2554 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002555
Georg Brandl27a28582010-10-10 09:49:21 +00002556 * Update the seed() method to use all of the bits in a string instead of just
2557 the hash value. This makes better use of the seed value and assures the
2558 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002559
Georg Brandl27a28582010-10-10 09:49:21 +00002560 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2561 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2562 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002563
2564 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002583- hashlib has two new constant attributes: algorithms_guaranteed and
2584 algorithms_avaiable that respectively list the names of hash algorithms
2585 guaranteed to exist in all Python implementations and the names of hash
2586 algorithms available in the current process.

2715 return characters from the full Unicode range, even on narrow unicode builds
2716 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2717 in Python is that unicodedata.numeric() now returns the correct value for
2718 large code points, and repr() may consider more characters as printable.
2719
Victor Stinner6c00c142010-08-17 23:37:11 +00002720- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Victor Stinner47fcb5b2010-08-13 23:59:58 +00002736- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00002737 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2738 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00002744- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2745 use PyUnicode_FromFormatV() to format the warning message.

2753 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002754
Georg Brandl649971e2010-09-05 17:06:50 +00002755- Issue #9416: Fix some issues with complex formatting where the output with no
2756 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002757
2758 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2759 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Georg Brandl62069d32010-07-31 08:56:11 +00003118- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3119 dealing with unary minus applied to a constant. The removed code was mutating
3120 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00003122- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003123 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003124 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003125 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003126
Victor Stinner25e8ec42010-06-25 00:02:38 +00003127- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use

3129
Victor Stinner06e49dd2010-06-13 18:21:50 +00003130- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003131 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003132 string formats.
3133
Georg Brandl62069d32010-07-31 08:56:11 +00003134- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003135 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3136 location of the raised exception.
3137
Victor Stinner313a1202010-06-11 23:56:51 +00003138- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3139 filenames and enable os.fsencode().

3142
Georg Brandl62069d32010-07-31 08:56:11 +00003143- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3144 interpreter with characters outside the Basic Multilingual Plane (higher than
3145 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003146
Georg Brandl62069d32010-07-31 08:56:11 +00003147- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3148 TypeError instead of giving a DeprecationWarning when a float is parsed using
3149 the 'L' code (for long long). (All other integer codes already raise
3150 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003151
Victor Stinner600d3be2010-06-10 12:00:55 +00003152- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3153 enable shortcuts for upper case encoding name. Add also a shortcut for
3154 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3155
Georg Brandl62069d32010-07-31 08:56:11 +00003156- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3157 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003158
3159- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003160 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003161 like bytearray.
3162
Georg Brandl62069d32010-07-31 08:56:11 +00003163- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003164 used anymore and it was never documented.
3165
Georg Brandl62069d32010-07-31 08:56:11 +00003166- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003167
Georg Brandl62069d32010-07-31 08:56:11 +00003168- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3169 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003170
Georg Brandl62069d32010-07-31 08:56:11 +00003171- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3172 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3173 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3174 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003175
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003176- Issue #8748: Fix two issues with comparisons between complex and integer
3177 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003178 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3179 (2) The comparison raised an OverflowError for large integers, leading to
3180 unpredictable exceptions when combining integers and complex objects in sets
3181 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003182

3184 Fix a crash if an empty directory called "encodings" exists in sys.path.
3185
Victor Stinner9ca9c252010-05-19 16:53:30 +00003186- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003187 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003188 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003189
Georg Brandl62069d32010-07-31 08:56:11 +00003190- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3191 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003192
Victor Stinnerae6265f2010-05-15 16:27:27 +00003193- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3194 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003195 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003196 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003197
Victor Stinner59e62db2010-05-15 13:14:32 +00003198- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003199 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003200
Victor Stinnerb744ba12010-05-15 12:27:16 +00003201- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003202 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003203 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3204
Victor Stinner0964ee12010-04-30 16:48:45 +00003205- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003206 PyUnicode_FromString() to support surrogates in the filename and use the right
3207 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003208
Georg Brandl8569e582010-05-19 20:57:08 +00003209- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3210
Georg Brandl62069d32010-07-31 08:56:11 +00003211- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.

Georg Brandl62069d32010-07-31 08:56:11 +00003223- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
3224 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00003225
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003226- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003227 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
3228 compared to the dynamic memory allocation fallback. Patch by Charles-François
3229 Natali.

Mark Dickinsonf673f0c2010-03-13 09:48:39 +00003260- Issue #7845: Rich comparison methods on the complex type now return
3261 NotImplemented rather than raising a TypeError when comparing with an
3262 incompatible type; this allows user-defined classes to implement their own
3263 comparisons with complex.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003310- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003311 where the right hand operand is a set of constants, by turning the set into a
3312 frozenset and pre-building it as a constant. The comparison operation is made
3313 against the constant instead of building a new set each time it is executed (a
3314 similar optimization already existed which turned a list of constants into a
3315 pre-built tuple). Patch and additional tests by Dave Malcolm.

3322 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3323 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3324 parsing certain long numeric strings corresponding to subnormal values, (3) a

3621 the performance hit anytime the cache is exceeded.

4022 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004023
4024 >>> Decimal(1.1)
4025 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004030- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4031 InvalidOperation instead of returning False. (Comparisons involving a quiet
4032 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4033 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004035- Issue #2531: Comparison operations between floats and Decimal instances now
4036 return a result based on the numeric values of the operands; previously they
4037 returned an arbitrary result based on the relative ordering of id(float) and
4038 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4039 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004043- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004044 argument `-` which tells it to read files to compile from stdin. Each line is
4045 read on demand and the named file is compiled immediately. (Original patch by
4046 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004048- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004052- Comparisons using one of <, <=, >, >= between a complex instance and a
4053 Fractions instance now raise TypeError instead of returning True/False. This
4054 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4055 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004098- The internals of the subprocess module on POSIX systems have been replaced by
4099 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4100 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004102- subprocess.Popen now has restore_signals and start_new_session features. The
4103 default of restore_signals=True is a new behavior compared to earlier Python
4104 versions. This means that signals such as SIGPIPE are not ignored by default
4105 in subprocesses launched by Python (Issue #1652).

4192 position when calling `truncate()`. It would previously change the file
4193 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004194 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4198 archive. The new implementation is significantly faster and can be wrapped in
4199 a :class:`io.BufferedReader` object for more speedups. It also solves an
4200 issue where interleaved calls to `read()` and `readline()` give wrong results.

Georg Brandl62069d32010-07-31 08:56:11 +00004537 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4538 PyPycLoader inherit from this class and provide implementations in relation to
4539 other methods required by the ABCs.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004598- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004599 compared to other unix systems. In particular, os.getgroups() does not reflect
4600 any changes made using os.setgroups() but basicly always returns the same
4601 information as the id command. os.getgroups() can now return more than 16
4602 groups on MacOSX.

4628 Prior to this change, timezone adjustment in utctimetuple() could produce
4629 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

4633 directive. When the ``%z`` directive is present in the format string, an
4634 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4635 ``datetime.timezone`` instance constructed from the parsed offset. If both
4636 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4637 name, but ``%Z`` data without ``%z`` is discarded.

4641 ``datetime.timezone``, return fixed name and UTC offset from their
4642 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4643 returns ``None``. A class attribute, ``utc`` contains an instance
4644 representing the UTC timezone. Original patch by Rafe Kaplan.

4670 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004671 the result is now always correctly rounded, and is equivalent to ``td /

Mark Hammond5a607a32009-05-06 08:04:54 +00005257- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5258 in all operations, including splitdrive, split, etc. splitunc() now issues
5259 a PendingDeprecation warning.
5260
Eric Smith63376222009-05-05 14:04:18 +00005261- Issue #5920: For float.__format__, change the behavior with the
5262 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5263 to be like 'g' but with at least one decimal point and with a
5264 default precision of 12. Previously, the behavior the same but with
5265 a default precision of 6. This more closely matches str(), and
5266 reduces surprises when adding alignment flags to the empty
5267 presentation type. This also affects the new complex.__format__ in
5268 the same way.
5269
Martin v. Löwis011e8422009-05-05 04:43:17 +00005270- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5271
R. David Murrayb18500d2009-05-04 22:59:07 +00005272- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5273 shadowed by classtype's, even if it was None. property now
5274 inserts the __doc__ into the subclass instance __dict__.
5275
Antoine Pitrou244651a2009-05-04 18:56:13 +00005276- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00005281- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5282 received a new method, detach(). detach() disconnects the underlying stream
5283 from the buffer or text IO and returns it.
5284
Mark Dickinson33841c32009-05-01 15:37:04 +00005285- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5286 floats with absolute value over 1e50. Also remove length
5287 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5288 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005289
Eric Smith741191f2009-05-06 13:08:15 +00005290- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005291 format(complex(1, 2./3), '.5') now produces a sensible result.
5292
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005293- Issue #5864: Fix empty format code formatting for floats so that it
5294 never gives more than the requested number of significant digits.
5295
Eric Smith6dc46f52009-04-27 20:39:49 +00005296- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

5303
Benjamin Peterson193152c2009-04-25 01:08:45 +00005304- Issue #5283: Setting __class__ in __del__ caused a segfault.
5305
Mark Dickinsonad476da2009-04-23 19:14:16 +00005306- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5307 z involves nans, infs or negative zeros.
5308
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005309- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005310
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005311- Issue #1869 (and many duplicates): make round(x, n) correctly
5312 rounded for a float x, by using the decimal <-> binary conversions
5313 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5314 consistently agrees with format(x, '.2f').
5315
Benjamin Petersonae937c02009-04-18 20:54:08 +00005316- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5317 some builtin types.
5318
Eric Smith0923d1d2009-04-16 20:16:10 +00005319- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5320
Eric Smith35e84722009-04-16 20:21:28 +00005321- Issue #5515: str.format() type 'n' combined with commas and leading
5322 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005323
5324- Implement PEP 378, Format Specifier for Thousands Separator, for
5325 floats.
5326
Mark Dickinson3370cce2009-04-17 22:40:53 +00005327- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005328 1e11, not 1e12. This avoids printing 13 significant digits in
5329 situations where only 12 of them are correct. Example problem
5330 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5331 long time.)
5332
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005333- Issue #1580: On most platforms, use a 'short' float repr: for a
5334 finite float x, repr(x) now outputs a string based on the shortest
5335 sequence of decimal digits that rounds to x. Previous behaviour was
5336 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005337 Another minor difference is that the new repr switches to
5338 exponential notation at 1e16 instead of the previous 1e17; this
5339 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005340
5341 There's a new sys attribute sys.float_repr_style, which takes
5342 the value 'short' to indicate that we're using short float repr,
5343 and 'legacy' if the short float repr isn't available for one
5344 reason or another.
5345
5346 The float repr change involves incorporating David Gay's 'perfect
5347 rounding' code into the Python core (it's in Python/dtoa.c). As a
5348 secondary consequence, all string-to-float and float-to-string
5349 conversions (including all float formatting operations) will be
5350 correctly rounded on these platforms.
5351
Georg Brandl5f90d792010-08-01 22:31:05 +00005352 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005353 this change does not apply.
5354
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005355- Issue #5759: float() didn't call __float__ on str subclasses.
5356
Georg Brandlabc38772009-04-12 15:51:51 +00005357- The string.maketrans() function is deprecated; there is a new static method
5358 maketrans() on the bytes and bytearray classes. This removes confusion about
5359 the types string.maketrans() is supposed to work with, and mirrors the
5360 methods available on the str class.
5361
R. David Murraydc6da8a2009-04-09 22:16:43 +00005362- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

5367
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005368- Issue #3739: The unicode-internal encoder now reports the number of characters

Benjamin Peterson8f76b492009-04-03 22:22:42 +00005506- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
5507
Benjamin Peterson7fe98532009-04-02 00:33:55 +00005508- Issue #5499: The 'c' code for argument parsing functions now only accepts a
5509 byte, and the 'C' code only accepts a unicode character.
5510
Georg Brandl406b3d82009-04-11 21:24:37 +00005511- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

5527
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005528- Issue #4688: Add a heuristic so that tuples and dicts containing only
5529 untrackable objects are not tracked by the garbage collector. This can
5530 reduce the size of collections and therefore the garbage collection overhead
5531 on long-running programs, depending on their particular use of datatypes.

5538 2**15 for the internal representation of integers, for performance
5539 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5540 --enable-big-digits option to configure, which overrides the
5541 default. Add sys.int_info structseq to provide information about
5542 the internal format.

Mark Dickinson081dfee2009-03-18 14:47:41 +00005544- Issue #4474: PyUnicode_FromWideChar now converts characters outside
5545 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5546 and sizeof(Py_UNICODE) == 2.
5547
Eric Smith8ec90442009-03-14 12:29:34 +00005548- Issue #5237: Allow auto-numbered fields in str.format(). For

Mark Dickinson87ec0852009-02-09 17:15:59 +00005654- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5655 it now forces its argument to double before testing for infinity.
5656
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005657- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5658 returns a non-number type.
5659
Benjamin Peterson87618552009-02-08 15:00:52 +00005660- Issue #5182: Removed memoryview.__str__.
5661
Mark Dickinsonc008a172009-02-01 13:59:22 +00005662- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5663 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005664 the type definition cmpfunc. The tp_compare slot has been renamed

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005666
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005667- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005668 were suppressing all exceptions. These include list() and bytearray().
5669
Mark Dickinson1124e712009-01-28 21:25:58 +00005670- Issue #4707: round(x, n) now returns an integer if x is an integer.
5671 Previously it returned a float.
5672
Antoine Pitroub52ec782009-01-25 16:34:23 +00005673- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5674 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5675 evaluation loop is compiled with a new dispatch mechanism which gives
5676 speedups of up to 20%, depending on the system, on various benchmarks.
5677
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005678- Issue #4874: Most builtin decoders now reject unicode input.

5686 optional module state data.
5687
Mark Dickinson8055afd2009-01-17 10:04:45 +00005688- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005689 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005690
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005691- Issue #4935: The overflow checking code in the expandtabs() method common
5692 to str, bytes and bytearray could be optimized away by the compiler, letting
5693 the interpreter segfault instead of raising an error.
5694
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005695- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5696 __next__ method.
5697
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005698- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5699 function no longer attempt to call the __long__ slot to convert an object
5700 to an integer. Only the __int__ and __trunc__ slots are examined.
5701
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005702- Issue #4893: Use NT threading on CE.
5703

5705
Antoine Pitrouab868312009-01-10 15:40:25 +00005706- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5707 common cases are optimized thanks to a dedicated fast path and a moderate
5708 amount of loop unrolling.
5709
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005710- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5711 collecting the oldest generation) so that allocating lots of objects without
5712 destroying them does not show quadratic performance. Based on a proposal by
5713 Martin von Löwis at
5714 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5715
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005716- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005717 having been closed (for instance, a read() call could return some
5718 previously buffered data). Patch by Dmitry Vasiliev.
5719
Antoine Pitrou05608432009-01-09 18:53:14 +00005720- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5721 flag to work properly. Furthermore, when specifying -u, the text stdout
5722 and stderr streams have line-by-line buffering enabled (the default being
5723 to buffer arbitrary chunks of data).
5724
Raymond Hettinger35631532009-01-09 03:58:09 +00005725- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5726 instead of ints (reducing its size from 4 to 8 times thereby reducing
5727 Python's overall memory).
5728
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005729- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5730 an existing .py counterpart, override the co_filename attributes of all
5731 code objects if the original filename is obsolete (which can happen if the
5732 file has been renamed, moved, or if it is accessed through different paths).
5733 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5734
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005735- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5736 one byte. Also fixes the meaning of len() so that it returns the number of
5737 items, rather than the size in bytes.
5738
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005739- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5740
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005741- Issue #4747: When the terminal does not use utf-8, executing a script with
5742 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5743
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005744- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5745 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005746
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005747- Issue #3680: Reference cycles created through a dict, set or deque iterator
5748 did not get collected.
5749
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005750- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5751 where the tp_hash and tp_dict slots are both NULL.
5752
Georg Brandlccc47b62008-12-28 11:44:14 +00005753- Issue #4759: None is now allowed as the first argument of
5754 bytearray.translate(). It was always allowed for bytes.translate().
5755
Skip Montanaro80072cb2008-12-23 03:51:14 +00005756- Added test case to ensure attempts to read from a file opened for writing
5757 fail.
5758
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005759- Issue #3106: Speedup some comparisons (str/str and int/int).

5762 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5763
Antoine Pitrou621601a2008-12-17 23:18:19 +00005764- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5765 print elapsed times, not only when some objects are uncollectable /
5766 unreachable. Original patch by Neil Schemenauer.
5767
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005768- Issue #3439: Add a bit_length method to int.
5769
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005770- Issue #2173: When getting device encoding, check that return value of
5771 nl_langinfo is not the empty string. This was causing silent build
5772 failures on OS X.
5773
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005774- Issue #4597: Fixed several opcodes that weren't always propagating
5775 exceptions.
5776
5777- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005778 context manager returns a value that cannot be converted to a bool.
5779
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005780- Issue #4445: Replace "sizeof(PyBytesObject)" with
5781 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5782 bytes instances. On a typical machine this saves 3 bytes of memory
5783 (on average) per allocation of a bytes instance.
5784
Christian Heimesa872de52008-12-05 08:26:55 +00005785- Issue #4533: File read operation was dreadfully slow due to a slowly
5786 growing read buffer. Fixed by using the same growth rate algorithm as
5787 Python 2.x.
5788
Antoine Pitrou5504e892008-12-06 21:27:53 +00005789- Issue #4509: Various issues surrounding resize of bytearray objects to
5790 which there are buffer exports (e.g. memoryview instances).
5791
Georg Brandlf9734072008-12-07 15:30:06 +00005792- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5793 method on file objects with closefd=False. The file descriptor is still
5794 kept open but the file object behaves like a closed file. The ``FileIO``
5795 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005796
Antoine Pitroubc420402008-12-07 20:14:49 +00005797- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5798 larger than 1.

5803
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005804- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5805 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5806 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5807 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00006409- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6410 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00006412- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6413 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6414 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6415 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00006417- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006418 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006419 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00006421- Issue #5083: New 'gui' resource for regrtest.
