Ned Deily657b2de2011-06-28 19:51:30 -0700522- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to

526 environment after Distutils set it. Instead, have Distutils set the the
527 deployment target only in the environment of each build subprocess. It is
528 still possible to globally override the default by setting
529 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be

531 was built.

1205 files in binary mode, using the email package's binary support to parse
1206 arbitrary email messages. StringIO and text file input is deprecated,

1236 keyword-only argument. The preceding positional argument was deprecated,
1237 so it made no sense to add filter as a positional argument.

Armin Ronacher8d96d772011-01-22 13:13:05 +00001264- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1265 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1266 of HTTP 1.1.
1267
Armin Ronacher59531282011-01-22 13:44:22 +00001268- To match the behaviour of HTTP server, the HTTP client library now also
1269 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1270 that for incoming headers which makes this behaviour now consistent in
1271 both incoming and outgoing direction.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002026- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2027 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002028 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002029 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002030 encoding and to encode command line arguments on this OS.

2035
Benjamin Peterson230b2062010-10-16 03:45:45 +00002036- Issue #9997: Don't let the name "top" have special significance in scope

2423 with a non-empty format string. This is an effort to future-proof user
2424 code. If a derived class does not currently implement __format__ but later
2425 adds its own __format__, it would most likely break user code that had
2426 supplied a format string. This will be changed to a DeprecationWaring in

Antoine Pitrou1df15362010-09-13 14:16:46 +00002429- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2430 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2431 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002433- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2434 functions from the libc caused the methods .upper() and lower() to become
2435 locale aware and created subtly wrong results.

Georg Brandl27a28582010-10-10 09:49:21 +00002437- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002440- Issue #4617: Previously it was illegal to delete a name from the local
2441 namespace if it occurs as a free variable in a nested block. This limitation
2442 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2443
Georg Brandl27a28582010-10-10 09:49:21 +00002444- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2445 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2446 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2447 single character on UCS-2 builds.

2451 memoryview), and gain support for the context management protocol.
2452
Antoine Pitrou079ce542010-09-08 12:37:10 +00002453- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00002482- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002483 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002484 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002485 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002510 retry the select() loop instead of bailing out. This is because select() can
2511 incorrectly report a socket as ready for reading (for example, if it received
2512 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002592- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002593 it possible for the user to create self-referencing ordered dictionaries which
2594 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002595 approach of using weakref proxies so that reference cycles never get created
2596 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +00002598- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2599 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002600 utf-8 in strict mode) . Patch written by David Watson.

Georg Brandl27a28582010-10-10 09:49:21 +00002602- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2603 environment variable to set the filesystem encoding at Python startup.
2604 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2605 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002611- The pprint module now supports printing OrderedDicts in their given order

Vinay Sajip121a1c42010-09-08 10:46:15 +00002614- Logging: Added QueueHandler class to facilitate logging usage with
2615 multiprocessing.
2616
Georg Brandl27a28582010-10-10 09:49:21 +00002617- Issue #9707: Rewritten reference implementation of threading.local which is
2618 friendlier towards reference cycles. This change is not normally visible
2619 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002620
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002621- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2622 still return the id of the parent process after it has exited. This process
2623 id may even have been reused by another unrelated process.
2624
Georg Brandl27a28582010-10-10 09:49:21 +00002625- Issue #9792: In case of connection failure, socket.create_connection() would
2626 swallow the exception and raise a new one, making it impossible to fetch the
2627 original errno, or to filter timeout errors. Now the original error is
2628 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002630- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2631 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2632 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002634- Updates to the random module:
2635
Georg Brandl27a28582010-10-10 09:49:21 +00002636 * Document which parts of the module are guaranteed to stay the same across
2637 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002638
Georg Brandl27a28582010-10-10 09:49:21 +00002639 * Update the seed() method to use all of the bits in a string instead of just
2640 the hash value. This makes better use of the seed value and assures the
2641 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002642
Georg Brandl27a28582010-10-10 09:49:21 +00002643 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2644 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2645 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002646
2647 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00002652- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
2653 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2654 given warning type was triggered by the code under test.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00002662- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002663 unsupported operation is attempted (for example, writing to a file open only
2664 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002666- hashlib has two new constant attributes: algorithms_guaranteed and
2667 algorithms_avaiable that respectively list the names of hash algorithms
2668 guaranteed to exist in all Python implementations and the names of hash
2669 algorithms available in the current process.
2670
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002671- A new package ``concurrent.futures`` as defined by PEP 3148.
2672
Benjamin Peterson568867a2010-09-11 16:02:03 +00002673C-API
2674-----
2675

2798 return characters from the full Unicode range, even on narrow unicode builds
2799 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2800 in Python is that unicodedata.numeric() now returns the correct value for
2801 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00002820 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2821 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00002827- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2828 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00002829

2836 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002837
Georg Brandl649971e2010-09-05 17:06:50 +00002838- Issue #9416: Fix some issues with complex formatting where the output with no
2839 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002840
2841 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2842 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Victor Stinner8182b712010-07-28 00:40:58 +00003174- Issue #8991: convertbuffer() rejects discontigious buffers.
3175
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00003176- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
3177 compiler.
3178
Benjamin Petersonccabcd42010-07-07 20:54:01 +00003179- Issue #8413: structsequence now subclasses tuple.
3180
Ezio Melotti57221d02010-07-01 07:32:02 +00003181- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003182 start byte and the continuation byte(s) are now considered invalid, instead of
3183 the number of bytes specified by the start byte. E.g.:
3184 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3185 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3186 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3187 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00003188
Georg Brandl62069d32010-07-31 08:56:11 +00003189- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3190 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00003191
Benjamin Peterson88968ad2010-06-25 19:30:21 +00003192- Be more specific in error messages about positional arguments.
3193
Victor Stinner4aae1eb2010-06-24 22:08:25 +00003194- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
3195 objects, as described in the documentation.

Georg Brandl62069d32010-07-31 08:56:11 +00003201- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3202 dealing with unary minus applied to a constant. The removed code was mutating
3203 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003204
Victor Stinner554f3f02010-06-16 23:33:54 +00003205- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003206 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003207 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003208 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003209
Victor Stinner25e8ec42010-06-25 00:02:38 +00003210- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3211 "w*" format instead. Add tests for "w*" format.
3212
Victor Stinner06e49dd2010-06-13 18:21:50 +00003213- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003214 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003215 string formats.
3216
Georg Brandl62069d32010-07-31 08:56:11 +00003217- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003218 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3219 location of the raised exception.
3220
Victor Stinner313a1202010-06-11 23:56:51 +00003221- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3222 filenames and enable os.fsencode().
3223
Benjamin Peterson285a6892010-06-22 19:21:52 +00003224- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3225
Georg Brandl62069d32010-07-31 08:56:11 +00003226- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3227 interpreter with characters outside the Basic Multilingual Plane (higher than
3228 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003229
Georg Brandl62069d32010-07-31 08:56:11 +00003230- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3231 TypeError instead of giving a DeprecationWarning when a float is parsed using
3232 the 'L' code (for long long). (All other integer codes already raise
3233 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003234
Victor Stinner600d3be2010-06-10 12:00:55 +00003235- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3236 enable shortcuts for upper case encoding name. Add also a shortcut for
3237 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3238
Georg Brandl62069d32010-07-31 08:56:11 +00003239- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3240 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003241
3242- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003243 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003244 like bytearray.
3245
Georg Brandl62069d32010-07-31 08:56:11 +00003246- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003247 used anymore and it was never documented.
3248
Georg Brandl62069d32010-07-31 08:56:11 +00003249- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003250
Georg Brandl62069d32010-07-31 08:56:11 +00003251- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3252 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003253
Georg Brandl62069d32010-07-31 08:56:11 +00003254- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3255 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3256 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3257 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003258
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003259- Issue #8748: Fix two issues with comparisons between complex and integer
3260 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003261 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3262 (2) The comparison raised an OverflowError for large integers, leading to
3263 unpredictable exceptions when combining integers and complex objects in sets
3264 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003265
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003266- Issue #8766: Initialize _warnings module before importing the first module.
3267 Fix a crash if an empty directory called "encodings" exists in sys.path.
3268
Victor Stinner9ca9c252010-05-19 16:53:30 +00003269- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003270 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003271 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003272
Georg Brandl62069d32010-07-31 08:56:11 +00003273- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3274 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003275
Victor Stinnerae6265f2010-05-15 16:27:27 +00003276- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3277 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003278 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003279 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003280
Victor Stinner59e62db2010-05-15 13:14:32 +00003281- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003282 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003283
Victor Stinnerb744ba12010-05-15 12:27:16 +00003284- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003285 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003286 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3287
Victor Stinner0964ee12010-04-30 16:48:45 +00003288- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003289 PyUnicode_FromString() to support surrogates in the filename and use the right
3290 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003291
Georg Brandl8569e582010-05-19 20:57:08 +00003292- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3293
Georg Brandl62069d32010-07-31 08:56:11 +00003294- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003295
Benjamin Petersonfb886362010-04-24 18:21:17 +00003296- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3297 arguments.
3298
Victor Stinner14284c22010-04-23 12:02:30 +00003299- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003300 indirectly Python signal handlers anymore because mywrite() ignores exceptions
3301 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00003302
Victor Stinner31be90b2010-04-22 19:38:16 +00003303- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
Georg Brandl62069d32010-07-31 08:56:11 +00003304 unicode string (eg. backslashreplace).
Victor Stinner31be90b2010-04-22 19:38:16 +00003305
Georg Brandl62069d32010-07-31 08:56:11 +00003306- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
3307 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00003308
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003309- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003310 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
3311 compared to the dynamic memory allocation fallback. Patch by Charles-François
3312 Natali.

3390 crash in many places because of the PyByteArray_AS_STRING() macro returning
3391 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003393- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003394 where the right hand operand is a set of constants, by turning the set into a
3395 frozenset and pre-building it as a constant. The comparison operation is made
3396 against the constant instead of building a new set each time it is executed (a
3397 similar optimization already existed which turned a list of constants into a
3398 pre-built tuple). Patch and additional tests by Dave Malcolm.

3425 least on IEEE 754 platforms), and in particular does not depend on the
3426 internal representation of an int.

3702 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003703 applications that use a lot of regular expressions and limits the impact of
3704 the performance hit anytime the cache is exceeded.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004077 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004078 relies on the system threading library, so as to avoid a semi-busy wait loop.

Georg Brandl62069d32010-07-31 08:56:11 +00004113- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4114 InvalidOperation instead of returning False. (Comparisons involving a quiet
4115 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4116 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004118- Issue #2531: Comparison operations between floats and Decimal instances now
4119 return a result based on the numeric values of the operands; previously they
4120 returned an arbitrary result based on the relative ordering of id(float) and
4121 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4122 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004123
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004124- Added a subtract() method to collections.Counter().
4125
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004126- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004127 argument `-` which tells it to read files to compile from stdin. Each line is
4128 read on demand and the named file is compiled immediately. (Original patch by
4129 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004131- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004135- Comparisons using one of <, <=, >, >= between a complex instance and a
4136 Fractions instance now raise TypeError instead of returning True/False. This
4137 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4138 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004181- The internals of the subprocess module on POSIX systems have been replaced by
4182 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4183 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004184
Georg Brandl62069d32010-07-31 08:56:11 +00004185- subprocess.Popen now has restore_signals and start_new_session features. The
4186 default of restore_signals=True is a new behavior compared to earlier Python
4187 versions. This means that signals such as SIGPIPE are not ignored by default
4188 in subprocesses launched by Python (Issue #1652).

4275 position when calling `truncate()`. It would previously change the file
4276 position to the given argument, which goes against the tradition of

4281 archive. The new implementation is significantly faster and can be wrapped in
4282 a :class:`io.BufferedReader` object for more speedups. It also solves an
4283 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00004619- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004620 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4621 PyPycLoader inherit from this class and provide implementations in relation to
4622 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004623
Brett Cannon64ef00f2009-07-20 03:19:18 +00004624- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4625 the documentation said it did even though the code in PyLoader relied on the
4626 abstract method required by ResourceLoader.
4627
Georg Brandl62069d32010-07-31 08:56:11 +00004628- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004681- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004682 compared to other unix systems. In particular, os.getgroups() does not reflect
4683 any changes made using os.setgroups() but basicly always returns the same
4684 information as the id command. os.getgroups() can now return more than 16
4685 groups on MacOSX.

4711 Prior to this change, timezone adjustment in utctimetuple() could produce
4712 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

4724 ``datetime.timezone``, return fixed name and UTC offset from their
4725 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always

5041 threads could return successfully while some Thread objects were still

5283 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5284 corrects a pydoc regression.
5285
Georg Brandl5f90d792010-08-01 22:31:05 +00005286- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005287 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005328*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005329
5330Core and Builtins
5331-----------------
5332
Mark Dickinson865e01a2009-05-07 16:37:01 +00005333- Issue #5914: Add new C API function PyOS_string_to_double, and
5334 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5335
Eric Smith741191f2009-05-06 13:08:15 +00005336- Issue #3382: float.__format__, complex.__format__, and %-formatting
5337 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5338 affects nan -> NAN and inf -> INF.
5339
Mark Hammond5a607a32009-05-06 08:04:54 +00005340- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5341 in all operations, including splitdrive, split, etc. splitunc() now issues
5342 a PendingDeprecation warning.
5343
Eric Smith63376222009-05-05 14:04:18 +00005344- Issue #5920: For float.__format__, change the behavior with the
5345 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5346 to be like 'g' but with at least one decimal point and with a
5347 default precision of 12. Previously, the behavior the same but with
5348 a default precision of 6. This more closely matches str(), and
5349 reduces surprises when adding alignment flags to the empty
5350 presentation type. This also affects the new complex.__format__ in
5351 the same way.
5352
Martin v. Löwis011e8422009-05-05 04:43:17 +00005353- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5354
R. David Murrayb18500d2009-05-04 22:59:07 +00005355- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5356 shadowed by classtype's, even if it was None. property now
5357 inserts the __doc__ into the subclass instance __dict__.
5358
Antoine Pitrou244651a2009-05-04 18:56:13 +00005359- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5360 sequences. Patch by Nick Barnes and Victor Stinner.
5361
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005362- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005363
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005364- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5365 received a new method, detach(). detach() disconnects the underlying stream
5366 from the buffer or text IO and returns it.
5367
Mark Dickinson33841c32009-05-01 15:37:04 +00005368- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5369 floats with absolute value over 1e50. Also remove length
5370 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5371 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005372
Eric Smith741191f2009-05-06 13:08:15 +00005373- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005374 format(complex(1, 2./3), '.5') now produces a sensible result.
5375
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005376- Issue #5864: Fix empty format code formatting for floats so that it
5377 never gives more than the requested number of significant digits.
5378
Eric Smith6dc46f52009-04-27 20:39:49 +00005379- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5380 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5381
Eric Smithcc32a112009-04-26 21:35:14 +00005382- Issue #5835: Deprecate PyOS_ascii_formatd.
5383
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005384- Issue #4971: Fix titlecase for characters that are their own
5385 titlecase, but not their own uppercase.
5386
Benjamin Peterson193152c2009-04-25 01:08:45 +00005387- Issue #5283: Setting __class__ in __del__ caused a segfault.
5388
Mark Dickinsonad476da2009-04-23 19:14:16 +00005389- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5390 z involves nans, infs or negative zeros.
5391
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005392- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005393
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005394- Issue #1869 (and many duplicates): make round(x, n) correctly
5395 rounded for a float x, by using the decimal <-> binary conversions
5396 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5397 consistently agrees with format(x, '.2f').
5398
Benjamin Petersonae937c02009-04-18 20:54:08 +00005399- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5400 some builtin types.
5401
Eric Smith0923d1d2009-04-16 20:16:10 +00005402- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5403
Eric Smith35e84722009-04-16 20:21:28 +00005404- Issue #5515: str.format() type 'n' combined with commas and leading
5405 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005406
5407- Implement PEP 378, Format Specifier for Thousands Separator, for
5408 floats.
5409
Mark Dickinson3370cce2009-04-17 22:40:53 +00005410- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005411 1e11, not 1e12. This avoids printing 13 significant digits in
5412 situations where only 12 of them are correct. Example problem
5413 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5414 long time.)
5415
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005416- Issue #1580: On most platforms, use a 'short' float repr: for a
5417 finite float x, repr(x) now outputs a string based on the shortest
5418 sequence of decimal digits that rounds to x. Previous behaviour was
5419 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005420 Another minor difference is that the new repr switches to
5421 exponential notation at 1e16 instead of the previous 1e17; this
5422 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005423
5424 There's a new sys attribute sys.float_repr_style, which takes
5425 the value 'short' to indicate that we're using short float repr,
5426 and 'legacy' if the short float repr isn't available for one
5427 reason or another.
5428
5429 The float repr change involves incorporating David Gay's 'perfect
5430 rounding' code into the Python core (it's in Python/dtoa.c). As a
5431 secondary consequence, all string-to-float and float-to-string
5432 conversions (including all float formatting operations) will be
5433 correctly rounded on these platforms.
5434
Georg Brandl5f90d792010-08-01 22:31:05 +00005435 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005436 this change does not apply.
5437
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005438- Issue #5759: float() didn't call __float__ on str subclasses.
5439
Georg Brandlabc38772009-04-12 15:51:51 +00005440- The string.maketrans() function is deprecated; there is a new static method
5441 maketrans() on the bytes and bytearray classes. This removes confusion about
5442 the types string.maketrans() is supposed to work with, and mirrors the
5443 methods available on the str class.
5444
R. David Murraydc6da8a2009-04-09 22:16:43 +00005445- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5446 its clarity and its speed.
5447
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005448- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005449 to avoid compiler warnings.
5450
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005451- Issue #3739: The unicode-internal encoder now reports the number of characters
5452 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00005589- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
5590
Benjamin Peterson7fe98532009-04-02 00:33:55 +00005591- Issue #5499: The 'c' code for argument parsing functions now only accepts a
5592 byte, and the 'C' code only accepts a unicode character.
5593
Georg Brandl406b3d82009-04-11 21:24:37 +00005594- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
5595 when hitting the recursion limit under certain circumstances.
5596
Brett Cannon0759dd62009-04-01 18:13:07 +00005597- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
5598
Georg Brandlab6f2f62009-03-31 04:16:10 +00005599- Fix a segfault when running test_exceptions with coverage, caused by
5600 insufficient checks in accessors of Exception.__context__.
5601
Guido van Rossum0ad59d42009-03-30 22:01:35 +00005602- Issue #5604: non-ASCII characters in module name passed to
5603 imp.find_module() were converted to UTF-8 while the path is
5604 converted to the default filesystem encoding, causing nonsense.
5605
Benjamin Peterson09832742009-03-26 17:15:46 +00005606- Issue #5126: str.isprintable() returned False for space characters.
5607
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005608- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5609 the end sys.path, for compatibility with the system install of Python.
5610
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005611- Issue #4688: Add a heuristic so that tuples and dicts containing only
5612 untrackable objects are not tracked by the garbage collector. This can
5613 reduce the size of collections and therefore the garbage collection overhead
5614 on long-running programs, depending on their particular use of datatypes.
5615
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005616- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

5619
Mark Dickinsonbd792642009-03-18 20:06:12 +00005620- Issue #4258: Make it possible to use base 2**30 instead of base
5621 2**15 for the internal representation of integers, for performance
5622 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5623 --enable-big-digits option to configure, which overrides the
5624 default. Add sys.int_info structseq to provide information about
5625 the internal format.
5626
Mark Dickinson081dfee2009-03-18 14:47:41 +00005627- Issue #4474: PyUnicode_FromWideChar now converts characters outside
5628 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5629 and sizeof(Py_UNICODE) == 2.
5630
Eric Smith8ec90442009-03-14 12:29:34 +00005631- Issue #5237: Allow auto-numbered fields in str.format(). For
5632 example: '{} {}'.format(1, 2) == '1 2'.
5633
Antoine Pitrou652e7072009-03-13 19:25:20 +00005634- Issue #5392: when a very low recursion limit was set, the interpreter would
5635 abort with a fatal error after the recursion limit was hit twice.
5636
Matthias Klose042f1332009-04-04 14:32:42 +00005637- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
5638 short file names.

R. David Murray548ac412009-04-02 19:44:43 +00005644 mailbox.MH.get_message().
5645
Hye-Shik Chang944820b2009-04-02 10:33:16 +00005646- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
5647 error substitutions from non-strict codec error callbacks in
5648 incrementalencoder and StreamWriter.
5649
Georg Brandl33c28812009-04-01 23:07:29 +00005650- Issue #5656: Fix the coverage reporting when running the test suite with

5668
Brett Cannon7f6b4f82009-03-30 21:30:26 +00005669- Issue #5236: Change time.strptime() to only take strings. Didn't work with
5670 bytes already but the failure was non-obvious.
5671
Jesse Noller7af4ef82009-03-30 16:47:15 +00005672- Issue #5177: Multiprocessing's SocketListener class now uses

5680
Benjamin Peterson59406a92009-03-26 17:10:29 +00005681- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
5682 io.BufferedRandom have been deprecated for removal in Python 3.2.
5683
Lars Gustäbel42e00912009-03-22 20:34:29 +00005684- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5685 forever on incomplete input. That caused tarfile.open() to hang when used
5686 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5687 partial bzip2 compressed data.
5688
Mark Dickinson79f52032009-03-17 23:12:51 +00005689- Issue #2110: Add support for thousands separator and 'n' type

5693 '>' alignment characters.
5694
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00005695- The error detection code in FileIO.close() could fail to reflect the `errno`
5696 value, and report it as -1 instead.
5697

5705
Mark Dickinsonae681df2009-03-21 10:26:31 +00005706- Issue #5463: In struct module, remove deprecated overflow wrapping
5707 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00005708 struct.error instead of returning b'\xff\xff\xff\xff'. The
5709 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5710 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005737- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5738 it now forces its argument to double before testing for infinity.
5739
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005740- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5741 returns a non-number type.
5742
Benjamin Peterson87618552009-02-08 15:00:52 +00005743- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005749
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005750- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005751 were suppressing all exceptions. These include list() and bytearray().
5752
Mark Dickinson1124e712009-01-28 21:25:58 +00005753- Issue #4707: round(x, n) now returns an integer if x is an integer.
5754 Previously it returned a float.

5757 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5758 evaluation loop is compiled with a new dispatch mechanism which gives
5759 speedups of up to 20%, depending on the system, on various benchmarks.

Georg Brandl65ce6ad2010-09-05 17:32:31 +00005772 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005773
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005774- Issue #4935: The overflow checking code in the expandtabs() method common
5775 to str, bytes and bytearray could be optimized away by the compiler, letting
5776 the interpreter segfault instead of raising an error.
5777
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005778- Issue #3720: Fix a crash when an iterator modifies its class and removes its

5790 common cases are optimized thanks to a dedicated fast path and a moderate
5791 amount of loop unrolling.
5792
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005793- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5794 collecting the oldest generation) so that allocating lots of objects without
5795 destroying them does not show quadratic performance. Based on a proposal by
5796 Martin von Löwis at
5797 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5798
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005799- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005800 having been closed (for instance, a read() call could return some
5801 previously buffered data). Patch by Dmitry Vasiliev.
5802
Antoine Pitrou05608432009-01-09 18:53:14 +00005803- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5804 flag to work properly. Furthermore, when specifying -u, the text stdout
5805 and stderr streams have line-by-line buffering enabled (the default being
5806 to buffer arbitrary chunks of data).
5807
Raymond Hettinger35631532009-01-09 03:58:09 +00005808- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5809 instead of ints (reducing its size from 4 to 8 times thereby reducing
5810 Python's overall memory).
5811
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005812- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5813 an existing .py counterpart, override the co_filename attributes of all
5814 code objects if the original filename is obsolete (which can happen if the
5815 file has been renamed, moved, or if it is accessed through different paths).
5816 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5817
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005818- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5819 one byte. Also fixes the meaning of len() so that it returns the number of
5820 items, rather than the size in bytes.
5821
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005822- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5823
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005824- Issue #4747: When the terminal does not use utf-8, executing a script with
5825 non-ascii characters in its name could fail with a "SyntaxError: None" error.

5831 did not get collected.
5832
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005833- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5834 where the tp_hash and tp_dict slots are both NULL.
5835
Georg Brandlccc47b62008-12-28 11:44:14 +00005836- Issue #4759: None is now allowed as the first argument of
5837 bytearray.translate(). It was always allowed for bytes.translate().
5838
Skip Montanaro80072cb2008-12-23 03:51:14 +00005839- Added test case to ensure attempts to read from a file opened for writing
5840 fail.

5846
Antoine Pitrou621601a2008-12-17 23:18:19 +00005847- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5848 print elapsed times, not only when some objects are uncollectable /
5849 unreachable. Original patch by Neil Schemenauer.
5850

5852
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005853- Issue #2173: When getting device encoding, check that return value of
5854 nl_langinfo is not the empty string. This was causing silent build
5855 failures on OS X.
5856
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005857- Issue #4597: Fixed several opcodes that weren't always propagating
5858 exceptions.
5859
5860- Issue #4589: Fixed exception handling when the __exit__ function of a

Antoine Pitrou08838b62009-01-21 00:55:13 +00006210- Issue #5008: When a file is opened in append mode with the new IO library,
6211 do an explicit seek to the end of file (so that e.g. tell() returns the

6243 appropriately when it is being used via socket.makefile() objects
6244 rather than delaying the close by waiting for garbage collection to do it.
6245
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006246- Issue #1696199: Add collections.Counter() for rapid and convenient

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006501 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006502 from test support, which does the conversion.
