14
Benjamin Peterson18d7d7a2011-07-29 18:27:44 -050015- Make type(None), type(Ellipsis), and type(NotImplemented) callable. They
16 return the respective singleton instances.

21 compiling them.
22
Raymond Hettinger66d2be82011-07-28 09:55:13 -070023- Issue #12647: The None object now has a __bool__() method that returns False.
24 Formerly, bool(None) returned False only because of special case logic
25 in PyObject_IsTrue().
26
Eric V. Smith12ebefc2011-07-18 14:03:41 -040027- Issue #12579: str.format_map() now raises a ValueError if used on a

37 cleared by the garbage collector. This fixes a segfault when an instance
38 and its type get caught in a reference cycle, and the instance's
39 deallocator calls one of the methods on the type (e.g. when subclassing
40 IOBase). Diagnosis and patch by Davide Rizzo.

Ned Deily657b2de2011-06-28 19:51:30 -0700421- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
422 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
423 interpreter process. This could cause failures in non-Distutils subprocesses
424 and was unreliable since tests or user programs could modify the interpreter
425 environment after Distutils set it. Instead, have Distutils set the the
426 deployment target only in the environment of each build subprocess. It is
427 still possible to globally override the default by setting
428 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
429 greater or equal to the default value, the value with which the interpreter

Nadeem Vawda3c01d162011-08-01 23:48:26 +02001157- Issue #11651: Improve the Makefile test targets to run more of the test suite
1158 more quickly. The --multiprocess option is now enabled by default, reducing
1159 the amount of time needed to run the tests. "make test" and "make quicktest"
1160 now include some resource-intensive tests, but no longer run the test suite
1161 twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides
1162 as an easy platform-independent way to run test suite with sensible defaults.

1171 with the ``-m`` (or ``--match``) option. This works with all test cases
1172 using the unittest module. This is useful with long test suites
1173 such as test_io or test_subprocess.

1193 Web site.

1440 files in binary mode, using the email package's binary support to parse

Steven Bethardb0270112011-01-24 21:02:50 +00001502
1503- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00001504 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00001505 that for incoming headers which makes this behaviour now consistent in
1506 both incoming and outgoing direction.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002261 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002262 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002263 encoding and to encode command line arguments on this OS.

2656 with a non-empty format string. This is an effort to future-proof user
2657 code. If a derived class does not currently implement __format__ but later
2658 adds its own __format__, it would most likely break user code that had
2659 supplied a format string. This will be changed to a DeprecationWaring in
2660 Python 3.3 and it will be an error in Python 3.4.

2674 namespace if it occurs as a free variable in a nested block. This limitation
2675 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).

Georg Brandl27a28582010-10-10 09:49:21 +00002677- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2678 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2679 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2680 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002715- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002716 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002717 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002718 replacement for old handle_accept() and avoids the user to call accept()

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002742- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002743 retry the select() loop instead of bailing out. This is because select() can
2744 incorrectly report a socket as ready for reading (for example, if it received
2745 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002792 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002825- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002826 it possible for the user to create self-referencing ordered dictionaries which
2827 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002828 approach of using weakref proxies so that reference cycles never get created
2829 in the first place.
2830
Victor Stinnercb043522010-09-10 23:49:04 +00002831- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2832 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002833 utf-8 in strict mode) . Patch written by David Watson.

Georg Brandl27a28582010-10-10 09:49:21 +00002835- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2836 environment variable to set the filesystem encoding at Python startup.
2837 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2838 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002840- Issue #9410: Various optimizations to the pickle module, leading to speedups
2841 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2842 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002843
Georg Brandl27a28582010-10-10 09:49:21 +00002844- The pprint module now supports printing OrderedDicts in their given order
2845 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00002847- Logging: Added QueueHandler class to facilitate logging usage with
2848 multiprocessing.
2849
Georg Brandl27a28582010-10-10 09:49:21 +00002850- Issue #9707: Rewritten reference implementation of threading.local which is
2851 friendlier towards reference cycles. This change is not normally visible
2852 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002853
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002854- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2855 still return the id of the parent process after it has exited. This process
2856 id may even have been reused by another unrelated process.
2857
Georg Brandl27a28582010-10-10 09:49:21 +00002858- Issue #9792: In case of connection failure, socket.create_connection() would
2859 swallow the exception and raise a new one, making it impossible to fetch the
2860 original errno, or to filter timeout errors. Now the original error is
2861 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002863- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2864 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2865 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002867- Updates to the random module:
2868
Georg Brandl27a28582010-10-10 09:49:21 +00002869 * Document which parts of the module are guaranteed to stay the same across
2870 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002871
Georg Brandl27a28582010-10-10 09:49:21 +00002872 * Update the seed() method to use all of the bits in a string instead of just
2873 the hash value. This makes better use of the seed value and assures the
2874 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002875
Georg Brandl27a28582010-10-10 09:49:21 +00002876 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2877 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2878 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002879
2880 * Improved documentation of arguments to randrange(). Issue #9379.

2901 guaranteed to exist in all Python implementations and the names of hash
2902 algorithms available in the current process.
2903

3032 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

Georg Brandl649971e2010-09-05 17:06:50 +00003060- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3061 use PyUnicode_FromFormatV() to format the warning message.

Georg Brandl649971e2010-09-05 17:06:50 +00003071- Issue #9416: Fix some issues with complex formatting where the output with no
3072 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003073
3074 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3075 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3404Core and Builtins
3405-----------------
3406
Victor Stinner8182b712010-07-28 00:40:58 +00003407- Issue #8991: convertbuffer() rejects discontigious buffers.
3408
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00003409- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
3410 compiler.
3411
Benjamin Petersonccabcd42010-07-07 20:54:01 +00003412- Issue #8413: structsequence now subclasses tuple.
3413
Ezio Melotti57221d02010-07-01 07:32:02 +00003414- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003415 start byte and the continuation byte(s) are now considered invalid, instead of
3416 the number of bytes specified by the start byte. E.g.:
3417 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3418 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3419 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3420 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00003421
Georg Brandl62069d32010-07-31 08:56:11 +00003422- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3423 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00003424
Benjamin Peterson88968ad2010-06-25 19:30:21 +00003425- Be more specific in error messages about positional arguments.
3426
Victor Stinner4aae1eb2010-06-24 22:08:25 +00003427- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
3428 objects, as described in the documentation.
3429
Victor Stinner0fe25a42010-06-17 23:08:50 +00003430- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Georg Brandl62069d32010-07-31 08:56:11 +00003431 Fix the encoding of the modules filename. Patch written by Amaury Forgeot

Victor Stinner0fe25a42010-06-17 23:08:50 +00003433
Georg Brandl62069d32010-07-31 08:56:11 +00003434- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3435 dealing with unary minus applied to a constant. The removed code was mutating
3436 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003437
Victor Stinner554f3f02010-06-16 23:33:54 +00003438- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003439 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003440 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003441 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003442
Victor Stinner25e8ec42010-06-25 00:02:38 +00003443- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3444 "w*" format instead. Add tests for "w*" format.
3445
Victor Stinner06e49dd2010-06-13 18:21:50 +00003446- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003447 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003448 string formats.
3449
Georg Brandl62069d32010-07-31 08:56:11 +00003450- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003451 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3452 location of the raised exception.
3453
Victor Stinner313a1202010-06-11 23:56:51 +00003454- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3455 filenames and enable os.fsencode().
3456
Benjamin Peterson285a6892010-06-22 19:21:52 +00003457- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3458
Georg Brandl62069d32010-07-31 08:56:11 +00003459- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3460 interpreter with characters outside the Basic Multilingual Plane (higher than
3461 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003462
Georg Brandl62069d32010-07-31 08:56:11 +00003463- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3464 TypeError instead of giving a DeprecationWarning when a float is parsed using
3465 the 'L' code (for long long). (All other integer codes already raise
3466 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003467
Victor Stinner600d3be2010-06-10 12:00:55 +00003468- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3469 enable shortcuts for upper case encoding name. Add also a shortcut for
3470 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3471
Georg Brandl62069d32010-07-31 08:56:11 +00003472- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3473 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003474
3475- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003476 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003477 like bytearray.
3478
Georg Brandl62069d32010-07-31 08:56:11 +00003479- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003480 used anymore and it was never documented.
3481
Georg Brandl62069d32010-07-31 08:56:11 +00003482- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003483
Georg Brandl62069d32010-07-31 08:56:11 +00003484- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3485 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003486
Georg Brandl62069d32010-07-31 08:56:11 +00003487- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3488 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3489 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3490 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003491
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003492- Issue #8748: Fix two issues with comparisons between complex and integer
3493 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003494 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3495 (2) The comparison raised an OverflowError for large integers, leading to
3496 unpredictable exceptions when combining integers and complex objects in sets
3497 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003498
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003499- Issue #8766: Initialize _warnings module before importing the first module.
3500 Fix a crash if an empty directory called "encodings" exists in sys.path.
3501
Victor Stinner9ca9c252010-05-19 16:53:30 +00003502- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003503 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003504 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003505
Georg Brandl62069d32010-07-31 08:56:11 +00003506- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3507 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003508
Victor Stinnerae6265f2010-05-15 16:27:27 +00003509- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3510 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003511 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003512 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003513
Victor Stinner59e62db2010-05-15 13:14:32 +00003514- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003515 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003516
Victor Stinnerb744ba12010-05-15 12:27:16 +00003517- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003518 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003519 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3520
Victor Stinner0964ee12010-04-30 16:48:45 +00003521- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003522 PyUnicode_FromString() to support surrogates in the filename and use the right
3523 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003524
Georg Brandl8569e582010-05-19 20:57:08 +00003525- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3526
Georg Brandl62069d32010-07-31 08:56:11 +00003527- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003528
Benjamin Petersonfb886362010-04-24 18:21:17 +00003529- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3530 arguments.
3531
Victor Stinner14284c22010-04-23 12:02:30 +00003532- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003533 indirectly Python signal handlers anymore because mywrite() ignores exceptions
3534 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00003535
Victor Stinner31be90b2010-04-22 19:38:16 +00003536- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing

Victor Stinner31be90b2010-04-22 19:38:16 +00003538
Georg Brandl62069d32010-07-31 08:56:11 +00003539- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
3540 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00003541
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003542- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003543 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
3544 compared to the dynamic memory allocation fallback. Patch by Charles-François
3545 Natali.

3623 crash in many places because of the PyByteArray_AS_STRING() macro returning
3624 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003626- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003627 where the right hand operand is a set of constants, by turning the set into a
3628 frozenset and pre-building it as a constant. The comparison operation is made
3629 against the constant instead of building a new set each time it is executed (a
3630 similar optimization already existed which turned a list of constants into a
3631 pre-built tuple). Patch and additional tests by Dave Malcolm.

3638 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3639 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3640 parsing certain long numeric strings corresponding to subnormal values, (3) a

3658 least on IEEE 754 platforms), and in particular does not depend on the
3659 internal representation of an int.

Georg Brandl62069d32010-07-31 08:56:11 +00003936 applications that use a lot of regular expressions and limits the impact of
3937 the performance hit anytime the cache is exceeded.

R. David Murrayb2416e52010-04-12 16:58:02 +00004317- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004318 filename and date, conforming to the 'standards' they were originally designed
4319 to follow. This improves compatibility with patch tools.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004335- Add functools.total_ordering() and functools.cmp_to_key().
4336
Georg Brandl62069d32010-07-31 08:56:11 +00004337- Issue #8257: The Decimal construct now accepts a float instance directly,
4338 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004339
4340 >>> Decimal(1.1)
4341 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004346- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4347 InvalidOperation instead of returning False. (Comparisons involving a quiet
4348 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4349 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004350
Georg Brandl62069d32010-07-31 08:56:11 +00004351- Issue #2531: Comparison operations between floats and Decimal instances now
4352 return a result based on the numeric values of the operands; previously they
4353 returned an arbitrary result based on the relative ordering of id(float) and
4354 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4355 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004356
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004357- Added a subtract() method to collections.Counter().
4358
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004359- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004360 argument `-` which tells it to read files to compile from stdin. Each line is
4361 read on demand and the named file is compiled immediately. (Original patch by
4362 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004364- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004368- Comparisons using one of <, <=, >, >= between a complex instance and a
4369 Fractions instance now raise TypeError instead of returning True/False. This
4370 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4371 <=> complex, and complex <=> complex comparisons.

4379
Antoine Pitrou910bd512010-03-22 20:11:09 +00004380- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004381 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00004414- The internals of the subprocess module on POSIX systems have been replaced by
4415 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4416 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004417
Georg Brandl62069d32010-07-31 08:56:11 +00004418- subprocess.Popen now has restore_signals and start_new_session features. The
4419 default of restore_signals=True is a new behavior compared to earlier Python
4420 versions. This means that signals such as SIGPIPE are not ignored by default
4421 in subprocesses launched by Python (Issue #1652).

4508 position when calling `truncate()`. It would previously change the file
4509 position to the given argument, which goes against the tradition of

4514 archive. The new implementation is significantly faster and can be wrapped in
4515 a :class:`io.BufferedReader` object for more speedups. It also solves an
4516 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004914- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004915 compared to other unix systems. In particular, os.getgroups() does not reflect
4916 any changes made using os.setgroups() but basicly always returns the same
4917 information as the id command. os.getgroups() can now return more than 16
4918 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00005254- Issue #6551: test_zipimport could import and then destroy some modules of the

Georg Brandl62069d32010-07-31 08:56:11 +00005273 leak-chasing test runs give sensible results. The previous method of reaping
5274 threads could return successfully while some Thread objects were still
5275 referenced. This also introduces a new private function:
Antoine Pitrou65c9c642009-10-30 17:25:12 +00005276 :func:`_thread._count()`.

5283
R. David Murray0bc11ae2009-10-18 22:18:17 +00005284- Issue #7058: Added save/restore for things like sys.argv and cwd to
Georg Brandl62069d32010-07-31 08:56:11 +00005285 runtest_inner in regrtest, with warnings if the called test modifies them, and

5559================================
5560
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005561*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005562
5563Core and Builtins
5564-----------------
5565
Mark Dickinson865e01a2009-05-07 16:37:01 +00005566- Issue #5914: Add new C API function PyOS_string_to_double, and
5567 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5568
Eric Smith741191f2009-05-06 13:08:15 +00005569- Issue #3382: float.__format__, complex.__format__, and %-formatting
5570 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5571 affects nan -> NAN and inf -> INF.
5572
Mark Hammond5a607a32009-05-06 08:04:54 +00005573- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5574 in all operations, including splitdrive, split, etc. splitunc() now issues
5575 a PendingDeprecation warning.
5576
Eric Smith63376222009-05-05 14:04:18 +00005577- Issue #5920: For float.__format__, change the behavior with the
5578 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5579 to be like 'g' but with at least one decimal point and with a
5580 default precision of 12. Previously, the behavior the same but with
5581 a default precision of 6. This more closely matches str(), and
5582 reduces surprises when adding alignment flags to the empty
5583 presentation type. This also affects the new complex.__format__ in
5584 the same way.
5585
Martin v. Löwis011e8422009-05-05 04:43:17 +00005586- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5587
R. David Murrayb18500d2009-05-04 22:59:07 +00005588- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5589 shadowed by classtype's, even if it was None. property now
5590 inserts the __doc__ into the subclass instance __dict__.
5591
Antoine Pitrou244651a2009-05-04 18:56:13 +00005592- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5593 sequences. Patch by Nick Barnes and Victor Stinner.
5594
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005595- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005596
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005597- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5598 received a new method, detach(). detach() disconnects the underlying stream
5599 from the buffer or text IO and returns it.
5600
Mark Dickinson33841c32009-05-01 15:37:04 +00005601- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5602 floats with absolute value over 1e50. Also remove length
5603 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5604 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005605
Eric Smith741191f2009-05-06 13:08:15 +00005606- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005607 format(complex(1, 2./3), '.5') now produces a sensible result.
5608
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005609- Issue #5864: Fix empty format code formatting for floats so that it
5610 never gives more than the requested number of significant digits.
5611
Eric Smith6dc46f52009-04-27 20:39:49 +00005612- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5613 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5614
Eric Smithcc32a112009-04-26 21:35:14 +00005615- Issue #5835: Deprecate PyOS_ascii_formatd.
5616
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005617- Issue #4971: Fix titlecase for characters that are their own
5618 titlecase, but not their own uppercase.
5619
Benjamin Peterson193152c2009-04-25 01:08:45 +00005620- Issue #5283: Setting __class__ in __del__ caused a segfault.
5621
Mark Dickinsonad476da2009-04-23 19:14:16 +00005622- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5623 z involves nans, infs or negative zeros.
5624
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005625- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005626
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005627- Issue #1869 (and many duplicates): make round(x, n) correctly
5628 rounded for a float x, by using the decimal <-> binary conversions
5629 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5630 consistently agrees with format(x, '.2f').
5631
Benjamin Petersonae937c02009-04-18 20:54:08 +00005632- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5633 some builtin types.
5634
Eric Smith0923d1d2009-04-16 20:16:10 +00005635- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5636
Eric Smith35e84722009-04-16 20:21:28 +00005637- Issue #5515: str.format() type 'n' combined with commas and leading
5638 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005639
5640- Implement PEP 378, Format Specifier for Thousands Separator, for
5641 floats.
5642
Mark Dickinson3370cce2009-04-17 22:40:53 +00005643- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005644 1e11, not 1e12. This avoids printing 13 significant digits in
5645 situations where only 12 of them are correct. Example problem
5646 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5647 long time.)
5648
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005649- Issue #1580: On most platforms, use a 'short' float repr: for a
5650 finite float x, repr(x) now outputs a string based on the shortest
5651 sequence of decimal digits that rounds to x. Previous behaviour was
5652 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005653 Another minor difference is that the new repr switches to
5654 exponential notation at 1e16 instead of the previous 1e17; this
5655 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005656
5657 There's a new sys attribute sys.float_repr_style, which takes
5658 the value 'short' to indicate that we're using short float repr,
5659 and 'legacy' if the short float repr isn't available for one
5660 reason or another.
5661
5662 The float repr change involves incorporating David Gay's 'perfect
5663 rounding' code into the Python core (it's in Python/dtoa.c). As a
5664 secondary consequence, all string-to-float and float-to-string
5665 conversions (including all float formatting operations) will be
5666 correctly rounded on these platforms.
5667
Georg Brandl5f90d792010-08-01 22:31:05 +00005668 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005669 this change does not apply.
5670
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005671- Issue #5759: float() didn't call __float__ on str subclasses.
5672
Georg Brandlabc38772009-04-12 15:51:51 +00005673- The string.maketrans() function is deprecated; there is a new static method
5674 maketrans() on the bytes and bytearray classes. This removes confusion about
5675 the types string.maketrans() is supposed to work with, and mirrors the
5676 methods available on the str class.
5677
R. David Murraydc6da8a2009-04-09 22:16:43 +00005678- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5679 its clarity and its speed.
5680
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005681- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005682 to avoid compiler warnings.
5683
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005684- Issue #3739: The unicode-internal encoder now reports the number of characters
5685 consumed like any other encoder (instead of the number of bytes).

5825 byte, and the 'C' code only accepts a unicode character.
5826
Georg Brandl406b3d82009-04-11 21:24:37 +00005827- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
5828 when hitting the recursion limit under certain circumstances.
5829
Brett Cannon0759dd62009-04-01 18:13:07 +00005830- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
5831
Georg Brandlab6f2f62009-03-31 04:16:10 +00005832- Fix a segfault when running test_exceptions with coverage, caused by
5833 insufficient checks in accessors of Exception.__context__.
5834
Guido van Rossum0ad59d42009-03-30 22:01:35 +00005835- Issue #5604: non-ASCII characters in module name passed to
5836 imp.find_module() were converted to UTF-8 while the path is
5837 converted to the default filesystem encoding, causing nonsense.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005841- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5842 the end sys.path, for compatibility with the system install of Python.
5843
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005844- Issue #4688: Add a heuristic so that tuples and dicts containing only
5845 untrackable objects are not tracked by the garbage collector. This can
5846 reduce the size of collections and therefore the garbage collection overhead
5847 on long-running programs, depending on their particular use of datatypes.
5848
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005849- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

5851 are now between 50% and 150% faster.
5852
Mark Dickinsonbd792642009-03-18 20:06:12 +00005853- Issue #4258: Make it possible to use base 2**30 instead of base
5854 2**15 for the internal representation of integers, for performance
5855 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5856 --enable-big-digits option to configure, which overrides the
5857 default. Add sys.int_info structseq to provide information about
5858 the internal format.
5859
Mark Dickinson081dfee2009-03-18 14:47:41 +00005860- Issue #4474: PyUnicode_FromWideChar now converts characters outside
5861 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5862 and sizeof(Py_UNICODE) == 2.
5863
Eric Smith8ec90442009-03-14 12:29:34 +00005864- Issue #5237: Allow auto-numbered fields in str.format(). For

5866
Antoine Pitrou652e7072009-03-13 19:25:20 +00005867- Issue #5392: when a very low recursion limit was set, the interpreter would
5868 abort with a fatal error after the recursion limit was hit twice.
5869
Matthias Klose042f1332009-04-04 14:32:42 +00005870- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

Lars Gustäbel42e00912009-03-22 20:34:29 +00005917- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5918 forever on incomplete input. That caused tarfile.open() to hang when used
5919 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

5959 used when using str.format() with str, int, and float arguments.
5960
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005961- Issue #5249: time.strftime returned malformed string when format string
5962 contained non ascii character on windows.
5963
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005964- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5965 source has already been decoded into str.
5966
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005967- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5968 rotating the object pointer by 4 bits to the right.
5969
Mark Dickinson87ec0852009-02-09 17:15:59 +00005970- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5971 it now forces its argument to double before testing for infinity.
5972
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005973- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5974 returns a non-number type.
5975
Benjamin Peterson87618552009-02-08 15:00:52 +00005976- Issue #5182: Removed memoryview.__str__.
5977
Mark Dickinsonc008a172009-02-01 13:59:22 +00005978- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5979 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005980 the type definition cmpfunc. The tp_compare slot has been renamed
5981 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005982
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005983- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005984 were suppressing all exceptions. These include list() and bytearray().
5985
Mark Dickinson1124e712009-01-28 21:25:58 +00005986- Issue #4707: round(x, n) now returns an integer if x is an integer.
5987 Previously it returned a float.
5988
Antoine Pitroub52ec782009-01-25 16:34:23 +00005989- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5990 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5991 evaluation loop is compiled with a new dispatch mechanism which gives
5992 speedups of up to 20%, depending on the system, on various benchmarks.
5993
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005994- Issue #4874: Most builtin decoders now reject unicode input.

6002 optional module state data.
6003
Mark Dickinson8055afd2009-01-17 10:04:45 +00006004- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006005 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006006
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006007- Issue #4935: The overflow checking code in the expandtabs() method common
6008 to str, bytes and bytearray could be optimized away by the compiler, letting
6009 the interpreter segfault instead of raising an error.
6010
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006011- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6012 __next__ method.
6013
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006014- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6015 function no longer attempt to call the __long__ slot to convert an object
6016 to an integer. Only the __int__ and __trunc__ slots are examined.
6017

6021
Antoine Pitrouab868312009-01-10 15:40:25 +00006022- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6023 common cases are optimized thanks to a dedicated fast path and a moderate
6024 amount of loop unrolling.
6025
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006026- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6027 collecting the oldest generation) so that allocating lots of objects without
6028 destroying them does not show quadratic performance. Based on a proposal by
6029 Martin von Löwis at
6030 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6031
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006032- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006033 having been closed (for instance, a read() call could return some
6034 previously buffered data). Patch by Dmitry Vasiliev.
6035
Antoine Pitrou05608432009-01-09 18:53:14 +00006036- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6037 flag to work properly. Furthermore, when specifying -u, the text stdout
6038 and stderr streams have line-by-line buffering enabled (the default being
6039 to buffer arbitrary chunks of data).
6040
Raymond Hettinger35631532009-01-09 03:58:09 +00006041- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6042 instead of ints (reducing its size from 4 to 8 times thereby reducing
6043 Python's overall memory).
6044
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006045- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6046 an existing .py counterpart, override the co_filename attributes of all
6047 code objects if the original filename is obsolete (which can happen if the
6048 file has been renamed, moved, or if it is accessed through different paths).
6049 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6050
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006051- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6052 one byte. Also fixes the meaning of len() so that it returns the number of
6053 items, rather than the size in bytes.
6054
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006055- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6056
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006057- Issue #4747: When the terminal does not use utf-8, executing a script with
6058 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6059
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006060- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6061 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006062
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006063- Issue #3680: Reference cycles created through a dict, set or deque iterator
6064 did not get collected.
6065
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006066- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6067 where the tp_hash and tp_dict slots are both NULL.
6068
Georg Brandlccc47b62008-12-28 11:44:14 +00006069- Issue #4759: None is now allowed as the first argument of
6070 bytearray.translate(). It was always allowed for bytes.translate().
6071
Skip Montanaro80072cb2008-12-23 03:51:14 +00006072- Added test case to ensure attempts to read from a file opened for writing
6073 fail.
6074
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006075- Issue #3106: Speedup some comparisons (str/str and int/int).

6078 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6079
Antoine Pitrou621601a2008-12-17 23:18:19 +00006080- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6081 print elapsed times, not only when some objects are uncollectable /
6082 unreachable. Original patch by Neil Schemenauer.
6083
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006084- Issue #3439: Add a bit_length method to int.
6085
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006086- Issue #2173: When getting device encoding, check that return value of
6087 nl_langinfo is not the empty string. This was causing silent build
6088 failures on OS X.
6089
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006090- Issue #4597: Fixed several opcodes that weren't always propagating
6091 exceptions.
6092
6093- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006094 context manager returns a value that cannot be converted to a bool.
6095
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006096- Issue #4445: Replace "sizeof(PyBytesObject)" with
6097 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6098 bytes instances. On a typical machine this saves 3 bytes of memory
6099 (on average) per allocation of a bytes instance.
6100
Christian Heimesa872de52008-12-05 08:26:55 +00006101- Issue #4533: File read operation was dreadfully slow due to a slowly
6102 growing read buffer. Fixed by using the same growth rate algorithm as
6103 Python 2.x.
6104
Antoine Pitrou5504e892008-12-06 21:27:53 +00006105- Issue #4509: Various issues surrounding resize of bytearray objects to

6442
Antoine Pitrou08838b62009-01-21 00:55:13 +00006443- Issue #5008: When a file is opened in append mode with the new IO library,
6444 do an explicit seek to the end of file (so that e.g. tell() returns the
6445 file size rather than 0). This is consistent with the behaviour of the
6446 traditional 2.x file object.

6476 appropriately when it is being used via socket.makefile() objects
6477 rather than delaying the close by waiting for garbage collection to do it.
6478
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006479- Issue #1696199: Add collections.Counter() for rapid and convenient

Antoine Pitrou88909542009-06-29 13:54:42 +00006725- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6726 regression tests in parallel, shortening the total runtime.
6727
Guilherme Polo2a998fa2009-06-21 17:40:07 +00006728- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6729 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6730 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6731 skip the tests if DISPLAY is defined but can't be used.
6732
R. David Murraya21e4ca2009-03-31 23:16:50 +00006733- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006734 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006735 from test support, which does the conversion.
6736
Guilherme Polo9de29af2009-01-28 20:40:48 +00006737- Issue #5083: New 'gui' resource for regrtest.
