509 environment after Distutils set it. Instead, have Distutils set the the
510 deployment target only in the environment of each build subprocess. It is
511 still possible to globally override the default by setting

514 was built.

R. David Murrayb7deff12011-01-30 06:21:28 +00001187- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
1188 files in binary mode, using the email package's binary support to parse
1189 arbitrary email messages. StringIO and text file input is deprecated,
1190 and string input fails early if non-ASCII characters are used, where
1191 previously it would fail when the email was processed in a later step.
1192
Nick Coghlan793ee1f2011-01-30 01:24:08 +00001193- Issue #10845: Mitigate the incompatibility between the multiprocessing

1204 obscured.
1205
Ned Deily70063932011-01-29 18:29:01 +00001206- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the

Raymond Hettingera63a3122011-01-26 20:34:14 +00001218- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
1219 keyword-only argument. The preceding positional argument was deprecated,
1220 so it made no sense to add filter as a positional argument.
1221
Raymond Hettinger512d2cc2011-01-25 21:32:39 +00001222- Issue #11004: Repaired edge case in deque.count().

Victor Stinner4ee65a92011-01-22 10:30:29 +00001235 filenames, at bootstrap, if the codec registry is not ready yet. It is still
1236 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +00001237 for all file entries in the ZIP file.

1245 a symbol named FSTAT.
1246
Armin Ronacher8d96d772011-01-22 13:13:05 +00001247- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1248 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1249 of HTTP 1.1.
1250
Armin Ronacher59531282011-01-22 13:44:22 +00001251- To match the behaviour of HTTP server, the HTTP client library now also
1252 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1253 that for incoming headers which makes this behaviour now consistent in
1254 both incoming and outgoing direction.
1255
Steven Bethardb0270112011-01-24 21:02:50 +00001256- Issue #9509: argparse now properly handles IOErrors raised by

1260 during request handling.
1261
Georg Brandl0f6b47a2011-01-30 12:19:35 +00001262- Issue #10680: Fix mutually exclusive arguments for argument groups in

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002012 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002387- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002388 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

2391
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002392- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2393 threads are still running. Instead, reinitialize the GIL on a second call to
2394 Py_Initialize().
2395
Georg Brandl27a28582010-10-10 09:49:21 +00002396- All SyntaxErrors now have a column offset and therefore a caret when the error
2397 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002398
Brett Cannonbc2eff32010-09-19 21:39:02 +00002399- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2400 module that was imported, but instead gets the module from sys.modules.
2401
Nick Coghlan37ee8502010-12-03 14:26:13 +00002402- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00002405- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2406 with a non-empty format string. This is an effort to future-proof user
2407 code. If a derived class does not currently implement __format__ but later
2408 adds its own __format__, it would most likely break user code that had
2409 supplied a format string. This will be changed to a DeprecationWaring in
2410 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002411
Antoine Pitrou1df15362010-09-13 14:16:46 +00002412- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2413 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2414 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2415
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002416- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2417 functions from the libc caused the methods .upper() and lower() to become
2418 locale aware and created subtly wrong results.
2419
Georg Brandl27a28582010-10-10 09:49:21 +00002420- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2421 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002422
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002423- Issue #4617: Previously it was illegal to delete a name from the local
2424 namespace if it occurs as a free variable in a nested block. This limitation
2425 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2426
Georg Brandl27a28582010-10-10 09:49:21 +00002427- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2428 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2429 Also, the "backslashreplace" error handler now joins surrogate pairs into a

Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002468 replacement for old handle_accept() and avoids the user to call accept()

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002575- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002576 it possible for the user to create self-referencing ordered dictionaries which
2577 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002578 approach of using weakref proxies so that reference cycles never get created
2579 in the first place.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002604- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2605 still return the id of the parent process after it has exited. This process
2606 id may even have been reused by another unrelated process.

Georg Brandl27a28582010-10-10 09:49:21 +00002622 * Update the seed() method to use all of the bits in a string instead of just
2623 the hash value. This makes better use of the seed value and assures the
2624 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002625
Georg Brandl27a28582010-10-10 09:49:21 +00002626 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2627 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2628 which has a slight bias whenever n is not a power of two. Issue #9025.

2630 * Improved documentation of arguments to randrange(). Issue #9379.

2651 guaranteed to exist in all Python implementations and the names of hash
2652 algorithms available in the current process.

2781 return characters from the full Unicode range, even on narrow unicode builds
2782 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2783 in Python is that unicodedata.numeric() now returns the correct value for
2784 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00002810- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2811 use PyUnicode_FromFormatV() to format the warning message.

2819 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002820
Georg Brandl649971e2010-09-05 17:06:50 +00002821- Issue #9416: Fix some issues with complex formatting where the output with no
2822 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002823
2824 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2825 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3156
Victor Stinner8182b712010-07-28 00:40:58 +00003157- Issue #8991: convertbuffer() rejects discontigious buffers.
3158
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00003159- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
3160 compiler.
3161
Benjamin Petersonccabcd42010-07-07 20:54:01 +00003162- Issue #8413: structsequence now subclasses tuple.
3163
Ezio Melotti57221d02010-07-01 07:32:02 +00003164- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003165 start byte and the continuation byte(s) are now considered invalid, instead of
3166 the number of bytes specified by the start byte. E.g.:
3167 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3168 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3169 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3170 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00003171
Georg Brandl62069d32010-07-31 08:56:11 +00003172- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3173 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00003174
Benjamin Peterson88968ad2010-06-25 19:30:21 +00003175- Be more specific in error messages about positional arguments.
3176
Victor Stinner4aae1eb2010-06-24 22:08:25 +00003177- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
3178 objects, as described in the documentation.
3179
Victor Stinner0fe25a42010-06-17 23:08:50 +00003180- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Georg Brandl62069d32010-07-31 08:56:11 +00003181 Fix the encoding of the modules filename. Patch written by Amaury Forgeot

Victor Stinner0fe25a42010-06-17 23:08:50 +00003183
Georg Brandl62069d32010-07-31 08:56:11 +00003184- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3185 dealing with unary minus applied to a constant. The removed code was mutating
3186 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003187
Victor Stinner554f3f02010-06-16 23:33:54 +00003188- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003189 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003190 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003191 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003192
Victor Stinner25e8ec42010-06-25 00:02:38 +00003193- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3194 "w*" format instead. Add tests for "w*" format.
3195
Victor Stinner06e49dd2010-06-13 18:21:50 +00003196- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003197 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003198 string formats.
3199
Georg Brandl62069d32010-07-31 08:56:11 +00003200- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003201 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3202 location of the raised exception.
3203
Victor Stinner313a1202010-06-11 23:56:51 +00003204- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3205 filenames and enable os.fsencode().
3206
Benjamin Peterson285a6892010-06-22 19:21:52 +00003207- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3208
Georg Brandl62069d32010-07-31 08:56:11 +00003209- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3210 interpreter with characters outside the Basic Multilingual Plane (higher than
3211 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003212
Georg Brandl62069d32010-07-31 08:56:11 +00003213- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3214 TypeError instead of giving a DeprecationWarning when a float is parsed using
3215 the 'L' code (for long long). (All other integer codes already raise
3216 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003217
Victor Stinner600d3be2010-06-10 12:00:55 +00003218- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3219 enable shortcuts for upper case encoding name. Add also a shortcut for
3220 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3221
Georg Brandl62069d32010-07-31 08:56:11 +00003222- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3223 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003224
3225- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003226 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003227 like bytearray.
3228
Georg Brandl62069d32010-07-31 08:56:11 +00003229- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003230 used anymore and it was never documented.
3231
Georg Brandl62069d32010-07-31 08:56:11 +00003232- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003233
Georg Brandl62069d32010-07-31 08:56:11 +00003234- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3235 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003236
Georg Brandl62069d32010-07-31 08:56:11 +00003237- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3238 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3239 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3240 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003241
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003242- Issue #8748: Fix two issues with comparisons between complex and integer
3243 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003244 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3245 (2) The comparison raised an OverflowError for large integers, leading to
3246 unpredictable exceptions when combining integers and complex objects in sets
3247 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003248
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003249- Issue #8766: Initialize _warnings module before importing the first module.
3250 Fix a crash if an empty directory called "encodings" exists in sys.path.
3251
Victor Stinner9ca9c252010-05-19 16:53:30 +00003252- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003253 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003254 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003255
Georg Brandl62069d32010-07-31 08:56:11 +00003256- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3257 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003258
Victor Stinnerae6265f2010-05-15 16:27:27 +00003259- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3260 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003261 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003262 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003263
Victor Stinner59e62db2010-05-15 13:14:32 +00003264- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003265 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003266
Victor Stinnerb744ba12010-05-15 12:27:16 +00003267- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003268 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003269 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3270
Victor Stinner0964ee12010-04-30 16:48:45 +00003271- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003272 PyUnicode_FromString() to support surrogates in the filename and use the right
3273 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003274
Georg Brandl8569e582010-05-19 20:57:08 +00003275- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3276
Georg Brandl62069d32010-07-31 08:56:11 +00003277- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003278
Benjamin Petersonfb886362010-04-24 18:21:17 +00003279- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3280 arguments.
3281
Victor Stinner14284c22010-04-23 12:02:30 +00003282- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003283 indirectly Python signal handlers anymore because mywrite() ignores exceptions
3284 (KeyboardInterrupt).

Victor Stinner31be90b2010-04-22 19:38:16 +00003288
Georg Brandl62069d32010-07-31 08:56:11 +00003289- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
3290 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00003291
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003292- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003293 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
3294 compared to the dynamic memory allocation fallback. Patch by Charles-François
3295 Natali.

Georg Brandl62069d32010-07-31 08:56:11 +00003372- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`) could
3373 crash in many places because of the PyByteArray_AS_STRING() macro returning
3374 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003376- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003377 where the right hand operand is a set of constants, by turning the set into a
3378 frozenset and pre-building it as a constant. The comparison operation is made
3379 against the constant instead of building a new set each time it is executed (a
3380 similar optimization already existed which turned a list of constants into a
3381 pre-built tuple). Patch and additional tests by Dave Malcolm.

3388 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3389 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3390 parsing certain long numeric strings corresponding to subnormal values, (3) a
3391 memory leak for some values large enough to cause overflow, and (4) a number
3392 of flaws that could lead to incorrectly rounded results.

3408 least on IEEE 754 platforms), and in particular does not depend on the
3409 internal representation of an int.

3683 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003684 simply clearing the entire cache on overflow to forgetting the least recently
3685 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003686 applications that use a lot of regular expressions and limits the impact of
3687 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003699- Issue #7989: Added pure python implementation of the `datetime` module. The C
3700 module is renamed to `_datetime` and if available, overrides all classes
3701 defined in datetime with fast C impementation. Python implementation is based
3702 on the original python prototype for the datetime module by Tim Peters with
3703 minor modifications by the PyPy project. The test suite now tests `datetime`
3704 module with and without `_datetime` acceleration using the same test cases.

R. David Murrayb2416e52010-04-12 16:58:02 +00004067- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004068 filename and date, conforming to the 'standards' they were originally designed
4069 to follow. This improves compatibility with patch tools.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004085- Add functools.total_ordering() and functools.cmp_to_key().
4086
Georg Brandl62069d32010-07-31 08:56:11 +00004087- Issue #8257: The Decimal construct now accepts a float instance directly,
4088 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004089
4090 >>> Decimal(1.1)
4091 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004096- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4097 InvalidOperation instead of returning False. (Comparisons involving a quiet
4098 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4099 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004100
Georg Brandl62069d32010-07-31 08:56:11 +00004101- Issue #2531: Comparison operations between floats and Decimal instances now
4102 return a result based on the numeric values of the operands; previously they
4103 returned an arbitrary result based on the relative ordering of id(float) and
4104 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4105 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004106
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004107- Added a subtract() method to collections.Counter().
4108
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004109- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004110 argument `-` which tells it to read files to compile from stdin. Each line is
4111 read on demand and the named file is compiled immediately. (Original patch by
4112 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004114- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4115 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00004116 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00004118- Comparisons using one of <, <=, >, >= between a complex instance and a
4119 Fractions instance now raise TypeError instead of returning True/False. This
4120 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4121 <=> complex, and complex <=> complex comparisons.

4129
Antoine Pitrou910bd512010-03-22 20:11:09 +00004130- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004131 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4132 silenced.

4138 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4139 reads and writes are always retried by OpenSSL itself.

Georg Brandl62069d32010-07-31 08:56:11 +00004164- The internals of the subprocess module on POSIX systems have been replaced by
4165 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4166 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004167
Georg Brandl62069d32010-07-31 08:56:11 +00004168- subprocess.Popen now has restore_signals and start_new_session features. The
4169 default of restore_signals=True is a new behavior compared to earlier Python
4170 versions. This means that signals such as SIGPIPE are not ignored by default
4171 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00004172

4258 position when calling `truncate()`. It would previously change the file
4259 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004260 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4261
Antoine Pitroua32f9a22010-01-27 21:18:57 +00004262- Issue #7610: Reworked implementation of the internal

4264 archive. The new implementation is significantly faster and can be wrapped in
4265 a :class:`io.BufferedReader` object for more speedups. It also solves an
4266 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004664- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004665 compared to other unix systems. In particular, os.getgroups() does not reflect
4666 any changes made using os.setgroups() but basicly always returns the same
4667 information as the id command. os.getgroups() can now return more than 16
4668 groups on MacOSX.

Brett Cannoncfed0292009-11-05 01:26:57 +00005014- Issue #7248 (part 2): Use a unique temporary directory for importlib source
5015 tests instead of tempfile.tempdir. This prevents the tests from sharing state
5016 between concurrent executions on the same system.

5024 threads could return successfully while some Thread objects were still
5025 referenced. This also introduces a new private function:

5033
R. David Murray0bc11ae2009-10-18 22:18:17 +00005034- Issue #7058: Added save/restore for things like sys.argv and cwd to
Georg Brandl62069d32010-07-31 08:56:11 +00005035 runtest_inner in regrtest, with warnings if the called test modifies them, and

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005311*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005312
5313Core and Builtins
5314-----------------
5315
Mark Dickinson865e01a2009-05-07 16:37:01 +00005316- Issue #5914: Add new C API function PyOS_string_to_double, and
5317 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5318
Eric Smith741191f2009-05-06 13:08:15 +00005319- Issue #3382: float.__format__, complex.__format__, and %-formatting
5320 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5321 affects nan -> NAN and inf -> INF.
5322
Mark Hammond5a607a32009-05-06 08:04:54 +00005323- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5324 in all operations, including splitdrive, split, etc. splitunc() now issues
5325 a PendingDeprecation warning.
5326
Eric Smith63376222009-05-05 14:04:18 +00005327- Issue #5920: For float.__format__, change the behavior with the
5328 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5329 to be like 'g' but with at least one decimal point and with a
5330 default precision of 12. Previously, the behavior the same but with
5331 a default precision of 6. This more closely matches str(), and
5332 reduces surprises when adding alignment flags to the empty
5333 presentation type. This also affects the new complex.__format__ in
5334 the same way.
5335
Martin v. Löwis011e8422009-05-05 04:43:17 +00005336- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5337
R. David Murrayb18500d2009-05-04 22:59:07 +00005338- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5339 shadowed by classtype's, even if it was None. property now
5340 inserts the __doc__ into the subclass instance __dict__.
5341
Antoine Pitrou244651a2009-05-04 18:56:13 +00005342- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5343 sequences. Patch by Nick Barnes and Victor Stinner.
5344
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005345- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005346
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005347- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5348 received a new method, detach(). detach() disconnects the underlying stream
5349 from the buffer or text IO and returns it.
5350
Mark Dickinson33841c32009-05-01 15:37:04 +00005351- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5352 floats with absolute value over 1e50. Also remove length
5353 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5354 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005355
Eric Smith741191f2009-05-06 13:08:15 +00005356- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005357 format(complex(1, 2./3), '.5') now produces a sensible result.
5358
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005359- Issue #5864: Fix empty format code formatting for floats so that it
5360 never gives more than the requested number of significant digits.
5361
Eric Smith6dc46f52009-04-27 20:39:49 +00005362- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5363 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5364
Eric Smithcc32a112009-04-26 21:35:14 +00005365- Issue #5835: Deprecate PyOS_ascii_formatd.
5366
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005367- Issue #4971: Fix titlecase for characters that are their own
5368 titlecase, but not their own uppercase.
5369
Benjamin Peterson193152c2009-04-25 01:08:45 +00005370- Issue #5283: Setting __class__ in __del__ caused a segfault.
5371
Mark Dickinsonad476da2009-04-23 19:14:16 +00005372- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5373 z involves nans, infs or negative zeros.
5374
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005375- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005376
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005377- Issue #1869 (and many duplicates): make round(x, n) correctly
5378 rounded for a float x, by using the decimal <-> binary conversions
5379 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5380 consistently agrees with format(x, '.2f').
5381
Benjamin Petersonae937c02009-04-18 20:54:08 +00005382- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5383 some builtin types.
5384
Eric Smith0923d1d2009-04-16 20:16:10 +00005385- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5386
Eric Smith35e84722009-04-16 20:21:28 +00005387- Issue #5515: str.format() type 'n' combined with commas and leading
5388 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005389
5390- Implement PEP 378, Format Specifier for Thousands Separator, for
5391 floats.
5392
Mark Dickinson3370cce2009-04-17 22:40:53 +00005393- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005394 1e11, not 1e12. This avoids printing 13 significant digits in
5395 situations where only 12 of them are correct. Example problem
5396 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5397 long time.)
5398
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005399- Issue #1580: On most platforms, use a 'short' float repr: for a
5400 finite float x, repr(x) now outputs a string based on the shortest
5401 sequence of decimal digits that rounds to x. Previous behaviour was
5402 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005403 Another minor difference is that the new repr switches to
5404 exponential notation at 1e16 instead of the previous 1e17; this
5405 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005406
5407 There's a new sys attribute sys.float_repr_style, which takes
5408 the value 'short' to indicate that we're using short float repr,
5409 and 'legacy' if the short float repr isn't available for one
5410 reason or another.
5411
5412 The float repr change involves incorporating David Gay's 'perfect
5413 rounding' code into the Python core (it's in Python/dtoa.c). As a
5414 secondary consequence, all string-to-float and float-to-string
5415 conversions (including all float formatting operations) will be
5416 correctly rounded on these platforms.
5417
Georg Brandl5f90d792010-08-01 22:31:05 +00005418 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005419 this change does not apply.
5420
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005421- Issue #5759: float() didn't call __float__ on str subclasses.
5422
Georg Brandlabc38772009-04-12 15:51:51 +00005423- The string.maketrans() function is deprecated; there is a new static method
5424 maketrans() on the bytes and bytearray classes. This removes confusion about
5425 the types string.maketrans() is supposed to work with, and mirrors the
5426 methods available on the str class.
5427
R. David Murraydc6da8a2009-04-09 22:16:43 +00005428- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5429 its clarity and its speed.
5430
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005431- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005432 to avoid compiler warnings.
5433
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005434- Issue #3739: The unicode-internal encoder now reports the number of characters
5435 consumed like any other encoder (instead of the number of bytes).

Guido van Rossum0ad59d42009-03-30 22:01:35 +00005585- Issue #5604: non-ASCII characters in module name passed to
5586 imp.find_module() were converted to UTF-8 while the path is
5587 converted to the default filesystem encoding, causing nonsense.
5588
Benjamin Peterson09832742009-03-26 17:15:46 +00005589- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005591- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5592 the end sys.path, for compatibility with the system install of Python.
5593
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005594- Issue #4688: Add a heuristic so that tuples and dicts containing only
5595 untrackable objects are not tracked by the garbage collector. This can
5596 reduce the size of collections and therefore the garbage collection overhead
5597 on long-running programs, depending on their particular use of datatypes.
5598
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005599- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
5600 improve its performance. Long divisions and remainder operations
5601 are now between 50% and 150% faster.
5602
Mark Dickinsonbd792642009-03-18 20:06:12 +00005603- Issue #4258: Make it possible to use base 2**30 instead of base
5604 2**15 for the internal representation of integers, for performance
5605 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5606 --enable-big-digits option to configure, which overrides the
5607 default. Add sys.int_info structseq to provide information about
5608 the internal format.
5609
Mark Dickinson081dfee2009-03-18 14:47:41 +00005610- Issue #4474: PyUnicode_FromWideChar now converts characters outside
5611 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5612 and sizeof(Py_UNICODE) == 2.
5613
Eric Smith8ec90442009-03-14 12:29:34 +00005614- Issue #5237: Allow auto-numbered fields in str.format(). For
5615 example: '{} {}'.format(1, 2) == '1 2'.
5616
Antoine Pitrou652e7072009-03-13 19:25:20 +00005617- Issue #5392: when a very low recursion limit was set, the interpreter would
5618 abort with a fatal error after the recursion limit was hit twice.
5619
Matthias Klose042f1332009-04-04 14:32:42 +00005620- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
5621 short file names.

5653 bytes already but the failure was non-obvious.
5654
Jesse Noller7af4ef82009-03-30 16:47:15 +00005655- Issue #5177: Multiprocessing's SocketListener class now uses

5666
Lars Gustäbel42e00912009-03-22 20:34:29 +00005667- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5668 forever on incomplete input. That caused tarfile.open() to hang when used
5669 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5670 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00005691 struct.error instead of returning b'\xff\xff\xff\xff'. The
5692 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

5709 used when using str.format() with str, int, and float arguments.
5710
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005711- Issue #5249: time.strftime returned malformed string when format string
5712 contained non ascii character on windows.
5713
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005714- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5715 source has already been decoded into str.
5716
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005717- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5718 rotating the object pointer by 4 bits to the right.
5719
Mark Dickinson87ec0852009-02-09 17:15:59 +00005720- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5721 it now forces its argument to double before testing for infinity.
5722
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005723- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5724 returns a non-number type.
5725
Benjamin Peterson87618552009-02-08 15:00:52 +00005726- Issue #5182: Removed memoryview.__str__.
5727
Mark Dickinsonc008a172009-02-01 13:59:22 +00005728- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5729 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005730 the type definition cmpfunc. The tp_compare slot has been renamed
5731 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005732
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005733- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005734 were suppressing all exceptions. These include list() and bytearray().
5735
Mark Dickinson1124e712009-01-28 21:25:58 +00005736- Issue #4707: round(x, n) now returns an integer if x is an integer.
5737 Previously it returned a float.
5738
Antoine Pitroub52ec782009-01-25 16:34:23 +00005739- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5740 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5741 evaluation loop is compiled with a new dispatch mechanism which gives
5742 speedups of up to 20%, depending on the system, on various benchmarks.
5743
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005744- Issue #4874: Most builtin decoders now reject unicode input.

5750
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005751- Issue #4838: When a module is deallocated, free the memory backing the
5752 optional module state data.
5753
Mark Dickinson8055afd2009-01-17 10:04:45 +00005754- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005755 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005756
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005757- Issue #4935: The overflow checking code in the expandtabs() method common
5758 to str, bytes and bytearray could be optimized away by the compiler, letting
5759 the interpreter segfault instead of raising an error.
5760
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005761- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5762 __next__ method.
5763
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005764- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5765 function no longer attempt to call the __long__ slot to convert an object
5766 to an integer. Only the __int__ and __trunc__ slots are examined.
5767
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005768- Issue #4893: Use NT threading on CE.

5771
Antoine Pitrouab868312009-01-10 15:40:25 +00005772- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5773 common cases are optimized thanks to a dedicated fast path and a moderate
5774 amount of loop unrolling.
5775
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005776- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5777 collecting the oldest generation) so that allocating lots of objects without
5778 destroying them does not show quadratic performance. Based on a proposal by
5779 Martin von Löwis at
5780 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5781
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005782- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005783 having been closed (for instance, a read() call could return some
5784 previously buffered data). Patch by Dmitry Vasiliev.
5785
Antoine Pitrou05608432009-01-09 18:53:14 +00005786- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5787 flag to work properly. Furthermore, when specifying -u, the text stdout
5788 and stderr streams have line-by-line buffering enabled (the default being
5789 to buffer arbitrary chunks of data).
5790
Raymond Hettinger35631532009-01-09 03:58:09 +00005791- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5792 instead of ints (reducing its size from 4 to 8 times thereby reducing
5793 Python's overall memory).
5794
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005795- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5796 an existing .py counterpart, override the co_filename attributes of all
5797 code objects if the original filename is obsolete (which can happen if the
5798 file has been renamed, moved, or if it is accessed through different paths).
5799 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5800
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005801- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5802 one byte. Also fixes the meaning of len() so that it returns the number of
5803 items, rather than the size in bytes.
5804
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005805- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5806
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005807- Issue #4747: When the terminal does not use utf-8, executing a script with
5808 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5809
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005810- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5811 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005812
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005813- Issue #3680: Reference cycles created through a dict, set or deque iterator
5814 did not get collected.
5815
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005816- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5817 where the tp_hash and tp_dict slots are both NULL.
5818
Georg Brandlccc47b62008-12-28 11:44:14 +00005819- Issue #4759: None is now allowed as the first argument of
5820 bytearray.translate(). It was always allowed for bytes.translate().
5821
Skip Montanaro80072cb2008-12-23 03:51:14 +00005822- Added test case to ensure attempts to read from a file opened for writing
5823 fail.
5824
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005825- Issue #3106: Speedup some comparisons (str/str and int/int).

5828 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5829
Antoine Pitrou621601a2008-12-17 23:18:19 +00005830- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5831 print elapsed times, not only when some objects are uncollectable /
5832 unreachable. Original patch by Neil Schemenauer.
5833
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005834- Issue #3439: Add a bit_length method to int.
5835
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005836- Issue #2173: When getting device encoding, check that return value of
5837 nl_langinfo is not the empty string. This was causing silent build
5838 failures on OS X.
5839
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005840- Issue #4597: Fixed several opcodes that weren't always propagating
5841 exceptions.
5842
5843- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005844 context manager returns a value that cannot be converted to a bool.
5845
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005846- Issue #4445: Replace "sizeof(PyBytesObject)" with
5847 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5848 bytes instances. On a typical machine this saves 3 bytes of memory
5849 (on average) per allocation of a bytes instance.
5850
Christian Heimesa872de52008-12-05 08:26:55 +00005851- Issue #4533: File read operation was dreadfully slow due to a slowly
5852 growing read buffer. Fixed by using the same growth rate algorithm as
5853 Python 2.x.
5854
Antoine Pitrou5504e892008-12-06 21:27:53 +00005855- Issue #4509: Various issues surrounding resize of bytearray objects to
5856 which there are buffer exports (e.g. memoryview instances).
5857
Georg Brandlf9734072008-12-07 15:30:06 +00005858- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5859 method on file objects with closefd=False. The file descriptor is still
5860 kept open but the file object behaves like a closed file. The ``FileIO``
5861 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005862
Antoine Pitroubc420402008-12-07 20:14:49 +00005863- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5864 larger than 1.
5865

6192
Antoine Pitrou08838b62009-01-21 00:55:13 +00006193- Issue #5008: When a file is opened in append mode with the new IO library,
6194 do an explicit seek to the end of file (so that e.g. tell() returns the
6195 file size rather than 0). This is consistent with the behaviour of the

6226 appropriately when it is being used via socket.makefile() objects
6227 rather than delaying the close by waiting for garbage collection to do it.
6228
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006229- Issue #1696199: Add collections.Counter() for rapid and convenient

6441 supporting objects as input no matter how it was compiled (built in
6442 implementations or external openssl library).
6443
Mark Dickinson29500f62009-01-15 15:36:10 +00006444- Issue #4397: Fix occasional test_socket failure on OS X.

Martin v. Löwisa9b54c72009-01-11 09:30:50 +00006446- Issue #4279: Fix build of parsermodule under Cygwin.
6447
Antoine Pitroubcd5cbe2009-01-08 21:17:16 +00006448- Issue #4751: hashlib now releases the GIL when hashing large buffers
6449 (with a hardwired threshold of 2048 bytes), allowing better parallelization
6450 on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.
6451
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006452- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
6453
Antoine Pitrou31f30b12009-01-02 17:34:35 +00006454- Issue #4738: Each zlib object now has a separate lock, allowing to compress
6455 or decompress several streams at once on multi-CPU systems. Also, the GIL
6456 is now released when computing the CRC of a large buffer. Patch by ebfe.
6457
Georg Brandlb1441c72009-01-03 22:33:39 +00006458- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.

6463 OpenBSD.
Amaury Forgeot d'Arcefae8c42008-11-21 23:08:09 +00006464
Antoine Pitrou3ad3a0d2008-12-18 17:08:32 +00006465- Issue #4583: array.array would not always prohibit resizing when a buffer
6466 has been exported, resulting in an interpreter crash when accessing the
6467 buffer.
6468
Martin v. Löwis841edad2008-11-30 10:36:49 +00006469
Jack Diederiche0cbd692009-04-01 04:27:09 +00006470- Issue #5228: Make functools.partial objects can now be pickled.

6474
Antoine Pitrou88909542009-06-29 13:54:42 +00006475- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6476 regression tests in parallel, shortening the total runtime.
6477
Guilherme Polo2a998fa2009-06-21 17:40:07 +00006478- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6479 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6480 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6481 skip the tests if DISPLAY is defined but can't be used.
6482
R. David Murraya21e4ca2009-03-31 23:16:50 +00006483- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006484 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006485 from test support, which does the conversion.
6486
Guilherme Polo9de29af2009-01-28 20:40:48 +00006487- Issue #5083: New 'gui' resource for regrtest.
