46 order to update to the current time. Also added keyword argument
47 handling to os.utimensat in order to remove the need for explicit None.

Ned Deily657b2de2011-06-28 19:51:30 -0700870- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
871 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
872 interpreter process. This could cause failures in non-Distutils subprocesses
873 and was unreliable since tests or user programs could modify the interpreter
874 environment after Distutils set it. Instead, have Distutils set the the
875 deployment target only in the environment of each build subprocess. It is
876 still possible to globally override the default by setting
877 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
878 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700879 was built. Also, implement the same handling in packaging.

1666 more quickly. The --multiprocess option is now enabled by default, reducing
1667 the amount of time needed to run the tests. "make test" and "make quicktest"
1668 now include some resource-intensive tests, but no longer run the test suite
1669 twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides
Éric Araujo4f996442011-10-19 06:02:24 +02001670 an easy platform-independent way to run test suite with sensible defaults.

Steven Bethardb0270112011-01-24 21:02:50 +00002020
2021- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00002022 encodes headers with iso-8859-1 (latin1) encoding. It was already doing

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002779 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002780 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002781 encoding and to encode command line arguments on this OS.

2784 filenames encoded to the filesystem encoding with the surrogateescape error

3164 Py_Initialize().
3165
Georg Brandl27a28582010-10-10 09:49:21 +00003166- All SyntaxErrors now have a column offset and therefore a caret when the error

Georg Brandl27a28582010-10-10 09:49:21 +00003175- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3176 with a non-empty format string. This is an effort to future-proof user
3177 code. If a derived class does not currently implement __format__ but later
3178 adds its own __format__, it would most likely break user code that had
3179 supplied a format string. This will be changed to a DeprecationWaring in
3180 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00003182- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3183 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3184 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3185
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003186- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3187 functions from the libc caused the methods .upper() and lower() to become
3188 locale aware and created subtly wrong results.
3189
Georg Brandl27a28582010-10-10 09:49:21 +00003190- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3191 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003192
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003193- Issue #4617: Previously it was illegal to delete a name from the local
3194 namespace if it occurs as a free variable in a nested block. This limitation
3195 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3196
Georg Brandl27a28582010-10-10 09:49:21 +00003197- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3198 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3199 Also, the "backslashreplace" error handler now joins surrogate pairs into a

Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003238 replacement for old handle_accept() and avoids the user to call accept()

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003345- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003346 it possible for the user to create self-referencing ordered dictionaries which
3347 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003348 approach of using weakref proxies so that reference cycles never get created
3349 in the first place.

3357 sys.setfilesystemencoding() creates inconsistencies because it is unable to

Georg Brandl27a28582010-10-10 09:49:21 +00003364- The pprint module now supports printing OrderedDicts in their given order

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003374- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3375 still return the id of the parent process after it has exited. This process
3376 id may even have been reused by another unrelated process.
3377
Georg Brandl27a28582010-10-10 09:49:21 +00003378- Issue #9792: In case of connection failure, socket.create_connection() would

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003387- Updates to the random module:
3388
Georg Brandl27a28582010-10-10 09:49:21 +00003389 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00003392 * Update the seed() method to use all of the bits in a string instead of just
3393 the hash value. This makes better use of the seed value and assures the
3394 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003395
Georg Brandl27a28582010-10-10 09:49:21 +00003396 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3397 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3398 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003399
3400 * Improved documentation of arguments to randrange(). Issue #9379.

3421 guaranteed to exist in all Python implementations and the names of hash
3422 algorithms available in the current process.

3551 return characters from the full Unicode range, even on narrow unicode builds
3552 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3553 in Python is that unicodedata.numeric() now returns the correct value for
3554 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00003580- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3581 use PyUnicode_FromFormatV() to format the warning message.

3589 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003590
Georg Brandl649971e2010-09-05 17:06:50 +00003591- Issue #9416: Fix some issues with complex formatting where the output with no
3592 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003593
3594 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3595 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3926
Victor Stinner8182b712010-07-28 00:40:58 +00003927- Issue #8991: convertbuffer() rejects discontigious buffers.
3928
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00003929- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
3930 compiler.
3931
Benjamin Petersonccabcd42010-07-07 20:54:01 +00003932- Issue #8413: structsequence now subclasses tuple.
3933
Ezio Melotti57221d02010-07-01 07:32:02 +00003934- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003935 start byte and the continuation byte(s) are now considered invalid, instead of
3936 the number of bytes specified by the start byte. E.g.:
3937 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3938 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3939 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3940 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00003941
Georg Brandl62069d32010-07-31 08:56:11 +00003942- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3943 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00003944
Benjamin Peterson88968ad2010-06-25 19:30:21 +00003945- Be more specific in error messages about positional arguments.
3946
Victor Stinner4aae1eb2010-06-24 22:08:25 +00003947- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
3948 objects, as described in the documentation.
3949
Victor Stinner0fe25a42010-06-17 23:08:50 +00003950- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Georg Brandl62069d32010-07-31 08:56:11 +00003951 Fix the encoding of the modules filename. Patch written by Amaury Forgeot

Victor Stinner0fe25a42010-06-17 23:08:50 +00003953
Georg Brandl62069d32010-07-31 08:56:11 +00003954- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3955 dealing with unary minus applied to a constant. The removed code was mutating
3956 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003957
Victor Stinner554f3f02010-06-16 23:33:54 +00003958- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003959 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003960 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003961 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003962
Victor Stinner25e8ec42010-06-25 00:02:38 +00003963- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3964 "w*" format instead. Add tests for "w*" format.
3965
Victor Stinner06e49dd2010-06-13 18:21:50 +00003966- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003967 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003968 string formats.
3969
Georg Brandl62069d32010-07-31 08:56:11 +00003970- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003971 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3972 location of the raised exception.
3973
Victor Stinner313a1202010-06-11 23:56:51 +00003974- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3975 filenames and enable os.fsencode().
3976
Benjamin Peterson285a6892010-06-22 19:21:52 +00003977- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3978
Georg Brandl62069d32010-07-31 08:56:11 +00003979- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3980 interpreter with characters outside the Basic Multilingual Plane (higher than
3981 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003982
Georg Brandl62069d32010-07-31 08:56:11 +00003983- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3984 TypeError instead of giving a DeprecationWarning when a float is parsed using
3985 the 'L' code (for long long). (All other integer codes already raise
3986 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003987
Victor Stinner600d3be2010-06-10 12:00:55 +00003988- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3989 enable shortcuts for upper case encoding name. Add also a shortcut for
3990 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3991
Georg Brandl62069d32010-07-31 08:56:11 +00003992- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3993 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003994
3995- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003996 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003997 like bytearray.
3998
Georg Brandl62069d32010-07-31 08:56:11 +00003999- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00004000 used anymore and it was never documented.
4001
Georg Brandl62069d32010-07-31 08:56:11 +00004002- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00004003
Georg Brandl62069d32010-07-31 08:56:11 +00004004- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
4005 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00004006
Georg Brandl62069d32010-07-31 08:56:11 +00004007- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
4008 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
4009 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
4010 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00004011
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004012- Issue #8748: Fix two issues with comparisons between complex and integer
4013 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00004014 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
4015 (2) The comparison raised an OverflowError for large integers, leading to
4016 unpredictable exceptions when combining integers and complex objects in sets
4017 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004018
Victor Stinner7d79b8b2010-05-19 20:40:50 +00004019- Issue #8766: Initialize _warnings module before importing the first module.
4020 Fix a crash if an empty directory called "encodings" exists in sys.path.
4021
Victor Stinner9ca9c252010-05-19 16:53:30 +00004022- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00004023 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00004024 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00004025
Georg Brandl62069d32010-07-31 08:56:11 +00004026- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
4027 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00004028
Victor Stinnerae6265f2010-05-15 16:27:27 +00004029- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
4030 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00004031 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00004032 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00004033
Victor Stinner59e62db2010-05-15 13:14:32 +00004034- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00004035 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00004036
Victor Stinnerb744ba12010-05-15 12:27:16 +00004037- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00004038 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00004039 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
4040
Victor Stinner0964ee12010-04-30 16:48:45 +00004041- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00004042 PyUnicode_FromString() to support surrogates in the filename and use the right
4043 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00004044
Georg Brandl8569e582010-05-19 20:57:08 +00004045- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
4046
Georg Brandl62069d32010-07-31 08:56:11 +00004047- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00004048
Benjamin Petersonfb886362010-04-24 18:21:17 +00004049- Issue #8419: Prevent the dict constructor from accepting non-string keyword
4050 arguments.
4051
Victor Stinner14284c22010-04-23 12:02:30 +00004052- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00004053 indirectly Python signal handlers anymore because mywrite() ignores exceptions
4054 (KeyboardInterrupt).

Victor Stinner31be90b2010-04-22 19:38:16 +00004058
Georg Brandl62069d32010-07-31 08:56:11 +00004059- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
4060 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00004061
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00004062- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00004063 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
4064 compared to the dynamic memory allocation fallback. Patch by Charles-François
4065 Natali.

Georg Brandl62069d32010-07-31 08:56:11 +00004142- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`) could
4143 crash in many places because of the PyByteArray_AS_STRING() macro returning
4144 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00004146- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00004147 where the right hand operand is a set of constants, by turning the set into a
4148 frozenset and pre-building it as a constant. The comparison operation is made
4149 against the constant instead of building a new set each time it is executed (a
4150 similar optimization already existed which turned a list of constants into a
4151 pre-built tuple). Patch and additional tests by Dave Malcolm.

4158 including: (1) a serious 'wrong output' bug that could occur for long (> 40
4159 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
4160 parsing certain long numeric strings corresponding to subnormal values, (3) a
4161 memory leak for some values large enough to cause overflow, and (4) a number
4162 of flaws that could lead to incorrectly rounded results.

4178 least on IEEE 754 platforms), and in particular does not depend on the
4179 internal representation of an int.

4453 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00004454 simply clearing the entire cache on overflow to forgetting the least recently
4455 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004456 applications that use a lot of regular expressions and limits the impact of
4457 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004469- Issue #7989: Added pure python implementation of the `datetime` module. The C
4470 module is renamed to `_datetime` and if available, overrides all classes
4471 defined in datetime with fast C impementation. Python implementation is based
4472 on the original python prototype for the datetime module by Tim Peters with
4473 minor modifications by the PyPy project. The test suite now tests `datetime`
4474 module with and without `_datetime` acceleration using the same test cases.

R. David Murrayb2416e52010-04-12 16:58:02 +00004837- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004838 filename and date, conforming to the 'standards' they were originally designed
4839 to follow. This improves compatibility with patch tools.

Georg Brandl62069d32010-07-31 08:56:11 +00004857- Issue #8257: The Decimal construct now accepts a float instance directly,
4858 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004859
4860 >>> Decimal(1.1)
4861 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004866- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4867 InvalidOperation instead of returning False. (Comparisons involving a quiet
4868 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4869 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004870
Georg Brandl62069d32010-07-31 08:56:11 +00004871- Issue #2531: Comparison operations between floats and Decimal instances now
4872 return a result based on the numeric values of the operands; previously they
4873 returned an arbitrary result based on the relative ordering of id(float) and
4874 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4875 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004876
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004877- Added a subtract() method to collections.Counter().
4878
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004879- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004880 argument `-` which tells it to read files to compile from stdin. Each line is
4881 read on demand and the named file is compiled immediately. (Original patch by
4882 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004884- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004888- Comparisons using one of <, <=, >, >= between a complex instance and a
4889 Fractions instance now raise TypeError instead of returning True/False. This
4890 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4891 <=> complex, and complex <=> complex comparisons.

4899
Antoine Pitrou910bd512010-03-22 20:11:09 +00004900- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004901 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00004934- The internals of the subprocess module on POSIX systems have been replaced by
4935 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4936 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004937
Georg Brandl62069d32010-07-31 08:56:11 +00004938- subprocess.Popen now has restore_signals and start_new_session features. The
4939 default of restore_signals=True is a new behavior compared to earlier Python
4940 versions. This means that signals such as SIGPIPE are not ignored by default
4941 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00004942

5028 position when calling `truncate()`. It would previously change the file
5029 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00005030 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

5034 archive. The new implementation is significantly faster and can be wrapped in
5035 a :class:`io.BufferedReader` object for more speedups. It also solves an
5036 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005434- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005435 compared to other unix systems. In particular, os.getgroups() does not reflect
5436 any changes made using os.setgroups() but basicly always returns the same
5437 information as the id command. os.getgroups() can now return more than 16
5438 groups on MacOSX.

5794 threads could return successfully while some Thread objects were still
5795 referenced. This also introduces a new private function:

5803
R. David Murray0bc11ae2009-10-18 22:18:17 +00005804- Issue #7058: Added save/restore for things like sys.argv and cwd to

Benjamin Petersonbd35b032009-04-04 23:16:41 +00006082
6083Core and Builtins
6084-----------------
6085
Mark Dickinson865e01a2009-05-07 16:37:01 +00006086- Issue #5914: Add new C API function PyOS_string_to_double, and
6087 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
6088
Eric Smith741191f2009-05-06 13:08:15 +00006089- Issue #3382: float.__format__, complex.__format__, and %-formatting
6090 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
6091 affects nan -> NAN and inf -> INF.
6092
Mark Hammond5a607a32009-05-06 08:04:54 +00006093- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
6094 in all operations, including splitdrive, split, etc. splitunc() now issues
6095 a PendingDeprecation warning.
6096
Eric Smith63376222009-05-05 14:04:18 +00006097- Issue #5920: For float.__format__, change the behavior with the
6098 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6099 to be like 'g' but with at least one decimal point and with a
6100 default precision of 12. Previously, the behavior the same but with
6101 a default precision of 6. This more closely matches str(), and
6102 reduces surprises when adding alignment flags to the empty
6103 presentation type. This also affects the new complex.__format__ in
6104 the same way.
6105
Martin v. Löwis011e8422009-05-05 04:43:17 +00006106- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
6107
R. David Murrayb18500d2009-05-04 22:59:07 +00006108- Issue #5890: in subclasses of 'property' the __doc__ attribute was
6109 shadowed by classtype's, even if it was None. property now
6110 inserts the __doc__ into the subclass instance __dict__.
6111
Antoine Pitrou244651a2009-05-04 18:56:13 +00006112- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
6113 sequences. Patch by Nick Barnes and Victor Stinner.
6114
Martin v. Löwise0a2b722009-05-10 08:08:56 +00006115- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00006116
Benjamin Petersond2e0c792009-05-01 20:40:59 +00006117- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6118 received a new method, detach(). detach() disconnects the underlying stream
6119 from the buffer or text IO and returns it.
6120
Mark Dickinson33841c32009-05-01 15:37:04 +00006121- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6122 floats with absolute value over 1e50. Also remove length
6123 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6124 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006125
Eric Smith741191f2009-05-06 13:08:15 +00006126- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006127 format(complex(1, 2./3), '.5') now produces a sensible result.
6128
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006129- Issue #5864: Fix empty format code formatting for floats so that it
6130 never gives more than the requested number of significant digits.
6131
Eric Smith6dc46f52009-04-27 20:39:49 +00006132- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6133 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6134
Eric Smithcc32a112009-04-26 21:35:14 +00006135- Issue #5835: Deprecate PyOS_ascii_formatd.
6136
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006137- Issue #4971: Fix titlecase for characters that are their own
6138 titlecase, but not their own uppercase.
6139
Benjamin Peterson193152c2009-04-25 01:08:45 +00006140- Issue #5283: Setting __class__ in __del__ caused a segfault.
6141
Mark Dickinsonad476da2009-04-23 19:14:16 +00006142- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6143 z involves nans, infs or negative zeros.
6144
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006145- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006146
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006147- Issue #1869 (and many duplicates): make round(x, n) correctly
6148 rounded for a float x, by using the decimal <-> binary conversions
6149 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6150 consistently agrees with format(x, '.2f').
6151
Benjamin Petersonae937c02009-04-18 20:54:08 +00006152- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6153 some builtin types.
6154
Eric Smith0923d1d2009-04-16 20:16:10 +00006155- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6156
Eric Smith35e84722009-04-16 20:21:28 +00006157- Issue #5515: str.format() type 'n' combined with commas and leading
6158 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006159
6160- Implement PEP 378, Format Specifier for Thousands Separator, for
6161 floats.
6162
Mark Dickinson3370cce2009-04-17 22:40:53 +00006163- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006164 1e11, not 1e12. This avoids printing 13 significant digits in
6165 situations where only 12 of them are correct. Example problem
6166 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6167 long time.)
6168
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006169- Issue #1580: On most platforms, use a 'short' float repr: for a
6170 finite float x, repr(x) now outputs a string based on the shortest
6171 sequence of decimal digits that rounds to x. Previous behaviour was
6172 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006173 Another minor difference is that the new repr switches to
6174 exponential notation at 1e16 instead of the previous 1e17; this
6175 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006176
6177 There's a new sys attribute sys.float_repr_style, which takes
6178 the value 'short' to indicate that we're using short float repr,
6179 and 'legacy' if the short float repr isn't available for one
6180 reason or another.
6181
6182 The float repr change involves incorporating David Gay's 'perfect
6183 rounding' code into the Python core (it's in Python/dtoa.c). As a
6184 secondary consequence, all string-to-float and float-to-string
6185 conversions (including all float formatting operations) will be
6186 correctly rounded on these platforms.
6187
Georg Brandl5f90d792010-08-01 22:31:05 +00006188 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006189 this change does not apply.
6190
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006191- Issue #5759: float() didn't call __float__ on str subclasses.
6192
Georg Brandlabc38772009-04-12 15:51:51 +00006193- The string.maketrans() function is deprecated; there is a new static method
6194 maketrans() on the bytes and bytearray classes. This removes confusion about
6195 the types string.maketrans() is supposed to work with, and mirrors the
6196 methods available on the str class.
6197
R. David Murraydc6da8a2009-04-09 22:16:43 +00006198- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6199 its clarity and its speed.
6200
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006201- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006202 to avoid compiler warnings.
6203
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006204- Issue #3739: The unicode-internal encoder now reports the number of characters
6205 consumed like any other encoder (instead of the number of bytes).

Guido van Rossum0ad59d42009-03-30 22:01:35 +00006355- Issue #5604: non-ASCII characters in module name passed to
6356 imp.find_module() were converted to UTF-8 while the path is
6357 converted to the default filesystem encoding, causing nonsense.
6358
Benjamin Peterson09832742009-03-26 17:15:46 +00006359- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00006361- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
6362 the end sys.path, for compatibility with the system install of Python.
6363
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006364- Issue #4688: Add a heuristic so that tuples and dicts containing only
6365 untrackable objects are not tracked by the garbage collector. This can
6366 reduce the size of collections and therefore the garbage collection overhead
6367 on long-running programs, depending on their particular use of datatypes.
6368
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00006369- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
6370 improve its performance. Long divisions and remainder operations
6371 are now between 50% and 150% faster.
6372
Mark Dickinsonbd792642009-03-18 20:06:12 +00006373- Issue #4258: Make it possible to use base 2**30 instead of base
6374 2**15 for the internal representation of integers, for performance
6375 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6376 --enable-big-digits option to configure, which overrides the
6377 default. Add sys.int_info structseq to provide information about
6378 the internal format.
6379
Mark Dickinson081dfee2009-03-18 14:47:41 +00006380- Issue #4474: PyUnicode_FromWideChar now converts characters outside
6381 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
6382 and sizeof(Py_UNICODE) == 2.
6383
Eric Smith8ec90442009-03-14 12:29:34 +00006384- Issue #5237: Allow auto-numbered fields in str.format(). For
6385 example: '{} {}'.format(1, 2) == '1 2'.
6386
Antoine Pitrou652e7072009-03-13 19:25:20 +00006387- Issue #5392: when a very low recursion limit was set, the interpreter would
6388 abort with a fatal error after the recursion limit was hit twice.
6389
Matthias Klose042f1332009-04-04 14:32:42 +00006390- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
6391 short file names.

6423 bytes already but the failure was non-obvious.
6424
Jesse Noller7af4ef82009-03-30 16:47:15 +00006425- Issue #5177: Multiprocessing's SocketListener class now uses

6436
Lars Gustäbel42e00912009-03-22 20:34:29 +00006437- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6438 forever on incomplete input. That caused tarfile.open() to hang when used
6439 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6440 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00006461 struct.error instead of returning b'\xff\xff\xff\xff'. The
6462 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

6479 used when using str.format() with str, int, and float arguments.
6480
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006481- Issue #5249: time.strftime returned malformed string when format string
6482 contained non ascii character on windows.
6483
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006484- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6485 source has already been decoded into str.
6486
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006487- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6488 rotating the object pointer by 4 bits to the right.
6489
Mark Dickinson87ec0852009-02-09 17:15:59 +00006490- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6491 it now forces its argument to double before testing for infinity.
6492
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006493- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6494 returns a non-number type.
6495
Benjamin Peterson87618552009-02-08 15:00:52 +00006496- Issue #5182: Removed memoryview.__str__.
6497
Mark Dickinsonc008a172009-02-01 13:59:22 +00006498- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6499 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006500 the type definition cmpfunc. The tp_compare slot has been renamed
6501 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006502
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006503- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006504 were suppressing all exceptions. These include list() and bytearray().
6505
Mark Dickinson1124e712009-01-28 21:25:58 +00006506- Issue #4707: round(x, n) now returns an integer if x is an integer.
6507 Previously it returned a float.
6508
Antoine Pitroub52ec782009-01-25 16:34:23 +00006509- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6510 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6511 evaluation loop is compiled with a new dispatch mechanism which gives
6512 speedups of up to 20%, depending on the system, on various benchmarks.
6513
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006514- Issue #4874: Most builtin decoders now reject unicode input.

6520
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00006521- Issue #4838: When a module is deallocated, free the memory backing the
6522 optional module state data.
6523
Mark Dickinson8055afd2009-01-17 10:04:45 +00006524- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006525 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006526
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006527- Issue #4935: The overflow checking code in the expandtabs() method common
6528 to str, bytes and bytearray could be optimized away by the compiler, letting
6529 the interpreter segfault instead of raising an error.
6530
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006531- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6532 __next__ method.
6533
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006534- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6535 function no longer attempt to call the __long__ slot to convert an object
6536 to an integer. Only the __int__ and __trunc__ slots are examined.
6537
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006538- Issue #4893: Use NT threading on CE.

6541
Antoine Pitrouab868312009-01-10 15:40:25 +00006542- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6543 common cases are optimized thanks to a dedicated fast path and a moderate
6544 amount of loop unrolling.
6545
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006546- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6547 collecting the oldest generation) so that allocating lots of objects without
6548 destroying them does not show quadratic performance. Based on a proposal by
6549 Martin von Löwis at
6550 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6551
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006552- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006553 having been closed (for instance, a read() call could return some
6554 previously buffered data). Patch by Dmitry Vasiliev.
6555
Antoine Pitrou05608432009-01-09 18:53:14 +00006556- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6557 flag to work properly. Furthermore, when specifying -u, the text stdout
6558 and stderr streams have line-by-line buffering enabled (the default being
6559 to buffer arbitrary chunks of data).
6560
Raymond Hettinger35631532009-01-09 03:58:09 +00006561- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6562 instead of ints (reducing its size from 4 to 8 times thereby reducing
6563 Python's overall memory).
6564
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006565- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6566 an existing .py counterpart, override the co_filename attributes of all
6567 code objects if the original filename is obsolete (which can happen if the
6568 file has been renamed, moved, or if it is accessed through different paths).
6569 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6570
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006571- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6572 one byte. Also fixes the meaning of len() so that it returns the number of
6573 items, rather than the size in bytes.
6574
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006575- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6576
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006577- Issue #4747: When the terminal does not use utf-8, executing a script with
6578 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6579
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006580- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6581 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006582
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006583- Issue #3680: Reference cycles created through a dict, set or deque iterator
6584 did not get collected.
6585
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006586- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6587 where the tp_hash and tp_dict slots are both NULL.
6588
Georg Brandlccc47b62008-12-28 11:44:14 +00006589- Issue #4759: None is now allowed as the first argument of
6590 bytearray.translate(). It was always allowed for bytes.translate().
6591
Skip Montanaro80072cb2008-12-23 03:51:14 +00006592- Added test case to ensure attempts to read from a file opened for writing
6593 fail.
6594
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006595- Issue #3106: Speedup some comparisons (str/str and int/int).

6598 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6599
Antoine Pitrou621601a2008-12-17 23:18:19 +00006600- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6601 print elapsed times, not only when some objects are uncollectable /
6602 unreachable. Original patch by Neil Schemenauer.
6603
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006604- Issue #3439: Add a bit_length method to int.
6605
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006606- Issue #2173: When getting device encoding, check that return value of
6607 nl_langinfo is not the empty string. This was causing silent build
6608 failures on OS X.
6609
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006610- Issue #4597: Fixed several opcodes that weren't always propagating
6611 exceptions.
6612
6613- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006614 context manager returns a value that cannot be converted to a bool.
6615
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006616- Issue #4445: Replace "sizeof(PyBytesObject)" with
6617 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6618 bytes instances. On a typical machine this saves 3 bytes of memory
6619 (on average) per allocation of a bytes instance.
6620
Christian Heimesa872de52008-12-05 08:26:55 +00006621- Issue #4533: File read operation was dreadfully slow due to a slowly
6622 growing read buffer. Fixed by using the same growth rate algorithm as
6623 Python 2.x.
6624
Antoine Pitrou5504e892008-12-06 21:27:53 +00006625- Issue #4509: Various issues surrounding resize of bytearray objects to
6626 which there are buffer exports (e.g. memoryview instances).
6627
Georg Brandlf9734072008-12-07 15:30:06 +00006628- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6629 method on file objects with closefd=False. The file descriptor is still
6630 kept open but the file object behaves like a closed file. The ``FileIO``
6631 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006632
Antoine Pitroubc420402008-12-07 20:14:49 +00006633- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6634 larger than 1.

Antoine Pitrou08838b62009-01-21 00:55:13 +00006963- Issue #5008: When a file is opened in append mode with the new IO library,
6964 do an explicit seek to the end of file (so that e.g. tell() returns the
6965 file size rather than 0). This is consistent with the behaviour of the

6996 appropriately when it is being used via socket.makefile() objects
6997 rather than delaying the close by waiting for garbage collection to do it.
6998
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006999- Issue #1696199: Add collections.Counter() for rapid and convenient

Gregory P. Smith365a1862009-02-12 07:35:29 +00007210- Issue #3745: Fix hashlib to always reject unicode and non buffer-api
7211 supporting objects as input no matter how it was compiled (built in
7212 implementations or external openssl library).
7213
Mark Dickinson29500f62009-01-15 15:36:10 +00007214- Issue #4397: Fix occasional test_socket failure on OS X.

Martin v. Löwisa9b54c72009-01-11 09:30:50 +00007216- Issue #4279: Fix build of parsermodule under Cygwin.
7217
Antoine Pitroubcd5cbe2009-01-08 21:17:16 +00007218- Issue #4751: hashlib now releases the GIL when hashing large buffers
7219 (with a hardwired threshold of 2048 bytes), allowing better parallelization
7220 on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.
7221
Martin v. Löwis5c88d812009-01-02 20:47:48 +00007222- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
7223
Antoine Pitrou31f30b12009-01-02 17:34:35 +00007224- Issue #4738: Each zlib object now has a separate lock, allowing to compress
7225 or decompress several streams at once on multi-CPU systems. Also, the GIL
7226 is now released when computing the CRC of a large buffer. Patch by ebfe.
7227
Georg Brandlb1441c72009-01-03 22:33:39 +00007228- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.
7229

7233 OpenBSD.
Amaury Forgeot d'Arcefae8c42008-11-21 23:08:09 +00007234
Antoine Pitrou3ad3a0d2008-12-18 17:08:32 +00007235- Issue #4583: array.array would not always prohibit resizing when a buffer
7236 has been exported, resulting in an interpreter crash when accessing the
7237 buffer.
7238
Martin v. Löwis841edad2008-11-30 10:36:49 +00007239
Jack Diederiche0cbd692009-04-01 04:27:09 +00007240- Issue #5228: Make functools.partial objects can now be pickled.

7244
Antoine Pitrou88909542009-06-29 13:54:42 +00007245- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
7246 regression tests in parallel, shortening the total runtime.
7247
Guilherme Polo2a998fa2009-06-21 17:40:07 +00007248- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
7249 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
7250 the same behaviour as test_ttkguionly (and now also test_tk) which is to
7251 skip the tests if DISPLAY is defined but can't be used.
7252
R. David Murraya21e4ca2009-03-31 23:16:50 +00007253- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00007254 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00007255 from test support, which does the conversion.
7256
Guilherme Polo9de29af2009-01-28 20:40:48 +00007257- Issue #5083: New 'gui' resource for regrtest.
