6===========================
7
8*Release date: XX-XXX-2011*
9
10Core and Builtins
11-----------------
12
Antoine Pitrou2be60af2012-01-24 17:44:06 +010013- Issue #11235: Fix OverflowError when trying to import a source file whose
14 modification time doesn't fit in a 32-bit timestamp.
15
Antoine Pitrou6c40eb72012-01-18 20:16:09 +010016- Fix the builtin module initialization code to store the init function for
17 future reinitialization.
18
Gregory P. Smith9564e4c2012-01-21 14:50:11 -080019- Issue #8052: The posix subprocess module would take a long time closing
20 all possible file descriptors in the child process rather than just open
21 file descriptors. It now closes only the open fds if possible for the
22 default close_fds=True behavior.
23
Meador Inge33880602012-01-15 19:15:36 -060024- Issue #13629: Renumber the tokens in token.h so that they match the indexes

26
Antoine Pitrou2e872082011-12-15 14:15:31 +010027- Fix the fix for issue #12149: it was incorrect, although it had the side
28 effect of appearing to resolve the issue. Thanks to Mark Shannon for
29 noticing.
30
Alexandre Vassalotti3bfc65a2011-12-13 13:08:09 -050031- Issue #13505: Pickle bytes objects in a way that is compatible with

35 given by Campbell Barton).
36
Antoine Pitrou11942a52011-11-28 19:08:36 +010037- Issue #7111: Python can now be run without a stdin, stdout or stderr
38 stream. It was already the case with Python 2. However, the corresponding
39 sys module entries are now set to None (instead of an unusable file object).
40
Amaury Forgeot d'Arc58e87612011-11-22 21:51:55 +010041- Issue #13436: Fix a bogus error message when an AST object was passed
42 an invalid integer value.
43
Petri Lehtinen8d40f162011-11-19 22:03:10 +020044- Issue #13338: Handle all enumerations in _Py_ANNOTATE_MEMORY_ORDER
45 to allow compiling extension modules with -Wswitch-enum on gcc.
46 Initial patch by Floris Bruynooghe.
47
Antoine Pitrou5418ee02011-11-15 01:42:21 +010048- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
49 already accepts them).
50
Antoine Pitrou0d776b12011-11-06 00:34:26 +010051- Issue #13342: input() used to ignore sys.stdin's and sys.stdout's unicode
52 error handler in interactive mode (when calling into PyOS_Readline()).
53
Amaury Forgeot d'Arc97c1bef2011-11-04 22:17:45 +010054- Issue #13343: Fix a SystemError when a lambda expression uses a global
55 variable in the default value of a keyword-only argument:
56 (lambda *, arg=GLOBAL_NAME: None)
57
Petri Lehtinencd06a142011-10-30 20:59:10 +020058- Issue #10519: Avoid unnecessary recursive function calls in
59 setobject.c.
60

Antoine Pitrou551ba202011-10-18 16:40:50 +020073- Issue #13188: When called without an explicit traceback argument,
74 generator.throw() now gets the traceback from the passed exception's
75 ``__traceback__`` attribute. Patch by Petri Lehtinen.
76
Mark Hammond6c58b282011-10-17 11:05:57 +110077- Issue #7833: Extension modules built using distutils on Windows will no
78 longer include a "manifest" to prevent them failing at import time in some
79 embedded situations.
80

784 and was unreliable since tests or user programs could modify the interpreter
785 environment after Distutils set it. Instead, have Distutils set the the
786 deployment target only in the environment of each build subprocess. It is
787 still possible to globally override the default by setting
788 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
789 greater or equal to the default value, the value with which the interpreter
790 was built.

R. David Murrayb7deff12011-01-30 06:21:28 +00001463- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
1464 files in binary mode, using the email package's binary support to parse
1465 arbitrary email messages. StringIO and text file input is deprecated,
1466 and string input fails early if non-ASCII characters are used, where
1467 previously it would fail when the email was processed in a later step.
1468
Nick Coghlan793ee1f2011-01-30 01:24:08 +00001469- Issue #10845: Mitigate the incompatibility between the multiprocessing

1479 preventing a confusing hung appearance on OS X with the windows
1480 obscured.
1481
Ned Deily70063932011-01-29 18:29:01 +00001482- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the

Raymond Hettingera63a3122011-01-26 20:34:14 +00001494- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
1495 keyword-only argument. The preceding positional argument was deprecated,
1496 so it made no sense to add filter as a positional argument.
1497
Raymond Hettinger512d2cc2011-01-25 21:32:39 +00001498- Issue #11004: Repaired edge case in deque.count().

Victor Stinner4ee65a92011-01-22 10:30:29 +00001511 filenames, at bootstrap, if the codec registry is not ready yet. It is still
1512 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +00001513 for all file entries in the ZIP file.

1521 a symbol named FSTAT.
1522
Armin Ronacher8d96d772011-01-22 13:13:05 +00001523- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1524 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1525 of HTTP 1.1.
1526
Armin Ronacher59531282011-01-22 13:44:22 +00001527- To match the behaviour of HTTP server, the HTTP client library now also
1528 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1529 that for incoming headers which makes this behaviour now consistent in
1530 both incoming and outgoing direction.
1531
Steven Bethardb0270112011-01-24 21:02:50 +00001532- Issue #9509: argparse now properly handles IOErrors raised by

1536 during request handling.
1537
Georg Brandl0f6b47a2011-01-30 12:19:35 +00001538- Issue #10680: Fix mutually exclusive arguments for argument groups in

1633 is made for all headers in any serialized message at serialization time. This
1634 provides protection against header injection attacks.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002285- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2286 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002287 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002288 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002289 encoding and to encode command line arguments on this OS.

2294
Benjamin Peterson230b2062010-10-16 03:45:45 +00002295- Issue #9997: Don't let the name "top" have special significance in scope

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002402 incorrectly validated some non-compliant applications as WSGI compliant; if

2682 with a non-empty format string. This is an effort to future-proof user
2683 code. If a derived class does not currently implement __format__ but later
2684 adds its own __format__, it would most likely break user code that had
2685 supplied a format string. This will be changed to a DeprecationWaring in
2686 Python 3.3 and it will be an error in Python 3.4.

2700 namespace if it occurs as a free variable in a nested block. This limitation
2701 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2702
Georg Brandl27a28582010-10-10 09:49:21 +00002703- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2704 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2705 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2706 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002741- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002742 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002743 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002744 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002769 retry the select() loop instead of bailing out. This is because select() can
2770 incorrectly report a socket as ready for reading (for example, if it received
2771 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002818 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002851- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002852 it possible for the user to create self-referencing ordered dictionaries which
2853 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002854 approach of using weakref proxies so that reference cycles never get created
2855 in the first place.
2856
Victor Stinnercb043522010-09-10 23:49:04 +00002857- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002861- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2862 environment variable to set the filesystem encoding at Python startup.
2863 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2864 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002870- The pprint module now supports printing OrderedDicts in their given order

2875
Georg Brandl27a28582010-10-10 09:49:21 +00002876- Issue #9707: Rewritten reference implementation of threading.local which is
2877 friendlier towards reference cycles. This change is not normally visible
2878 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002879
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002880- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2881 still return the id of the parent process after it has exited. This process
2882 id may even have been reused by another unrelated process.
2883
Georg Brandl27a28582010-10-10 09:49:21 +00002884- Issue #9792: In case of connection failure, socket.create_connection() would
2885 swallow the exception and raise a new one, making it impossible to fetch the
2886 original errno, or to filter timeout errors. Now the original error is
2887 re-raised.

2890 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2891 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002893- Updates to the random module:
2894
Georg Brandl27a28582010-10-10 09:49:21 +00002895 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002898 * Update the seed() method to use all of the bits in a string instead of just
2899 the hash value. This makes better use of the seed value and assures the
2900 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002901
Georg Brandl27a28582010-10-10 09:49:21 +00002902 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2903 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2904 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002905
2906 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002925- hashlib has two new constant attributes: algorithms_guaranteed and
2926 algorithms_avaiable that respectively list the names of hash algorithms
2927 guaranteed to exist in all Python implementations and the names of hash
2928 algorithms available in the current process.

3057 return characters from the full Unicode range, even on narrow unicode builds
3058 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3059 in Python is that unicodedata.numeric() now returns the correct value for
3060 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00003086- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3087 use PyUnicode_FromFormatV() to format the warning message.

3095 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003096
Georg Brandl649971e2010-09-05 17:06:50 +00003097- Issue #9416: Fix some issues with complex formatting where the output with no
3098 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003099
3100 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3101 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3439
Ezio Melotti57221d02010-07-01 07:32:02 +00003440- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003441 start byte and the continuation byte(s) are now considered invalid, instead of
3442 the number of bytes specified by the start byte. E.g.:
3443 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3444 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3445 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3446 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00003447
Georg Brandl62069d32010-07-31 08:56:11 +00003448- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3449 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00003450
Benjamin Peterson88968ad2010-06-25 19:30:21 +00003451- Be more specific in error messages about positional arguments.

Georg Brandl62069d32010-07-31 08:56:11 +00003460- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3461 dealing with unary minus applied to a constant. The removed code was mutating
3462 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003463
Victor Stinner554f3f02010-06-16 23:33:54 +00003464- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003465 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003466 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003467 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003468
Victor Stinner25e8ec42010-06-25 00:02:38 +00003469- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use

Georg Brandl62069d32010-07-31 08:56:11 +00003473 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003474 string formats.
3475
Georg Brandl62069d32010-07-31 08:56:11 +00003476- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003477 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3478 location of the raised exception.
3479
Victor Stinner313a1202010-06-11 23:56:51 +00003480- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3481 filenames and enable os.fsencode().
3482
Benjamin Peterson285a6892010-06-22 19:21:52 +00003483- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3484
Georg Brandl62069d32010-07-31 08:56:11 +00003485- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3486 interpreter with characters outside the Basic Multilingual Plane (higher than
3487 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003488
Georg Brandl62069d32010-07-31 08:56:11 +00003489- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3490 TypeError instead of giving a DeprecationWarning when a float is parsed using
3491 the 'L' code (for long long). (All other integer codes already raise
3492 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003493
Victor Stinner600d3be2010-06-10 12:00:55 +00003494- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3495 enable shortcuts for upper case encoding name. Add also a shortcut for
3496 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3497
Georg Brandl62069d32010-07-31 08:56:11 +00003498- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3499 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003500
3501- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003502 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003503 like bytearray.
3504
Georg Brandl62069d32010-07-31 08:56:11 +00003505- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003506 used anymore and it was never documented.
3507
Georg Brandl62069d32010-07-31 08:56:11 +00003508- In str.format(), raise a ValueError when indexes to arguments are too large.

3511 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003512
Georg Brandl62069d32010-07-31 08:56:11 +00003513- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3514 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3515 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3516 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003517
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003518- Issue #8748: Fix two issues with comparisons between complex and integer
3519 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003520 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3521 (2) The comparison raised an OverflowError for large integers, leading to
3522 unpredictable exceptions when combining integers and complex objects in sets
3523 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003524

3527
Victor Stinner9ca9c252010-05-19 16:53:30 +00003528- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003529 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003530 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003531
Georg Brandl62069d32010-07-31 08:56:11 +00003532- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3533 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003534
Victor Stinnerae6265f2010-05-15 16:27:27 +00003535- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3536 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003537 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003538 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003539
Victor Stinner59e62db2010-05-15 13:14:32 +00003540- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003541 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003542
Victor Stinnerb744ba12010-05-15 12:27:16 +00003543- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003544 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003545 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3546
Victor Stinner0964ee12010-04-30 16:48:45 +00003547- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003548 PyUnicode_FromString() to support surrogates in the filename and use the right
3549 encoding.

3650 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003652- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003653 where the right hand operand is a set of constants, by turning the set into a
3654 frozenset and pre-building it as a constant. The comparison operation is made
3655 against the constant instead of building a new set each time it is executed (a
3656 similar optimization already existed which turned a list of constants into a
3657 pre-built tuple). Patch and additional tests by Dave Malcolm.

3664 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3665 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3666 parsing certain long numeric strings corresponding to subnormal values, (3) a
3667 memory leak for some values large enough to cause overflow, and (4) a number
3668 of flaws that could lead to incorrectly rounded results.

3684 least on IEEE 754 platforms), and in particular does not depend on the
3685 internal representation of an int.

Georg Brandl62069d32010-07-31 08:56:11 +00003962 applications that use a lot of regular expressions and limits the impact of
3963 the performance hit anytime the cache is exceeded.

R. David Murrayb2416e52010-04-12 16:58:02 +00004343- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004344 filename and date, conforming to the 'standards' they were originally designed
4345 to follow. This improves compatibility with patch tools.

Georg Brandl62069d32010-07-31 08:56:11 +00004363- Issue #8257: The Decimal construct now accepts a float instance directly,
4364 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004365
4366 >>> Decimal(1.1)
4367 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004372- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4373 InvalidOperation instead of returning False. (Comparisons involving a quiet
4374 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4375 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004376
Georg Brandl62069d32010-07-31 08:56:11 +00004377- Issue #2531: Comparison operations between floats and Decimal instances now
4378 return a result based on the numeric values of the operands; previously they
4379 returned an arbitrary result based on the relative ordering of id(float) and
4380 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4381 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004382
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004383- Added a subtract() method to collections.Counter().
4384
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004385- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004386 argument `-` which tells it to read files to compile from stdin. Each line is
4387 read on demand and the named file is compiled immediately. (Original patch by
4388 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004390- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004394- Comparisons using one of <, <=, >, >= between a complex instance and a
4395 Fractions instance now raise TypeError instead of returning True/False. This
4396 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4397 <=> complex, and complex <=> complex comparisons.

4405
Antoine Pitrou910bd512010-03-22 20:11:09 +00004406- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004407 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00004440- The internals of the subprocess module on POSIX systems have been replaced by
4441 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4442 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004443
Georg Brandl62069d32010-07-31 08:56:11 +00004444- subprocess.Popen now has restore_signals and start_new_session features. The
4445 default of restore_signals=True is a new behavior compared to earlier Python
4446 versions. This means that signals such as SIGPIPE are not ignored by default
4447 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00004448

4534 position when calling `truncate()`. It would previously change the file
4535 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004536 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4540 archive. The new implementation is significantly faster and can be wrapped in
4541 a :class:`io.BufferedReader` object for more speedups. It also solves an
4542 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004940- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004941 compared to other unix systems. In particular, os.getgroups() does not reflect
4942 any changes made using os.setgroups() but basicly always returns the same
4943 information as the id command. os.getgroups() can now return more than 16
4944 groups on MacOSX.

Brett Cannoncfed0292009-11-05 01:26:57 +00005290- Issue #7248 (part 2): Use a unique temporary directory for importlib source
5291 tests instead of tempfile.tempdir. This prevents the tests from sharing state
5292 between concurrent executions on the same system.

5300 threads could return successfully while some Thread objects were still
5301 referenced. This also introduces a new private function:

5309
R. David Murray0bc11ae2009-10-18 22:18:17 +00005310- Issue #7058: Added save/restore for things like sys.argv and cwd to
Georg Brandl62069d32010-07-31 08:56:11 +00005311 runtest_inner in regrtest, with warnings if the called test modifies them, and

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005588
5589Core and Builtins
5590-----------------
5591
Mark Dickinson865e01a2009-05-07 16:37:01 +00005592- Issue #5914: Add new C API function PyOS_string_to_double, and
5593 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5594
Eric Smith741191f2009-05-06 13:08:15 +00005595- Issue #3382: float.__format__, complex.__format__, and %-formatting
5596 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5597 affects nan -> NAN and inf -> INF.
5598
Mark Hammond5a607a32009-05-06 08:04:54 +00005599- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5600 in all operations, including splitdrive, split, etc. splitunc() now issues
5601 a PendingDeprecation warning.
5602
Eric Smith63376222009-05-05 14:04:18 +00005603- Issue #5920: For float.__format__, change the behavior with the
5604 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5605 to be like 'g' but with at least one decimal point and with a
5606 default precision of 12. Previously, the behavior the same but with
5607 a default precision of 6. This more closely matches str(), and
5608 reduces surprises when adding alignment flags to the empty
5609 presentation type. This also affects the new complex.__format__ in
5610 the same way.
5611
Martin v. Löwis011e8422009-05-05 04:43:17 +00005612- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5613
R. David Murrayb18500d2009-05-04 22:59:07 +00005614- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5615 shadowed by classtype's, even if it was None. property now
5616 inserts the __doc__ into the subclass instance __dict__.
5617
Antoine Pitrou244651a2009-05-04 18:56:13 +00005618- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5619 sequences. Patch by Nick Barnes and Victor Stinner.
5620
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005621- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005622
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005623- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5624 received a new method, detach(). detach() disconnects the underlying stream
5625 from the buffer or text IO and returns it.
5626
Mark Dickinson33841c32009-05-01 15:37:04 +00005627- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5628 floats with absolute value over 1e50. Also remove length
5629 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5630 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005631
Eric Smith741191f2009-05-06 13:08:15 +00005632- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005633 format(complex(1, 2./3), '.5') now produces a sensible result.
5634
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005635- Issue #5864: Fix empty format code formatting for floats so that it
5636 never gives more than the requested number of significant digits.
5637
Eric Smith6dc46f52009-04-27 20:39:49 +00005638- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5639 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5640
Eric Smithcc32a112009-04-26 21:35:14 +00005641- Issue #5835: Deprecate PyOS_ascii_formatd.
5642
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005643- Issue #4971: Fix titlecase for characters that are their own
5644 titlecase, but not their own uppercase.
5645
Benjamin Peterson193152c2009-04-25 01:08:45 +00005646- Issue #5283: Setting __class__ in __del__ caused a segfault.
5647
Mark Dickinsonad476da2009-04-23 19:14:16 +00005648- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5649 z involves nans, infs or negative zeros.
5650
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005651- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005652
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005653- Issue #1869 (and many duplicates): make round(x, n) correctly
5654 rounded for a float x, by using the decimal <-> binary conversions
5655 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5656 consistently agrees with format(x, '.2f').
5657
Benjamin Petersonae937c02009-04-18 20:54:08 +00005658- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5659 some builtin types.
5660
Eric Smith0923d1d2009-04-16 20:16:10 +00005661- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5662
Eric Smith35e84722009-04-16 20:21:28 +00005663- Issue #5515: str.format() type 'n' combined with commas and leading
5664 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005665
5666- Implement PEP 378, Format Specifier for Thousands Separator, for
5667 floats.
5668
Mark Dickinson3370cce2009-04-17 22:40:53 +00005669- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005670 1e11, not 1e12. This avoids printing 13 significant digits in
5671 situations where only 12 of them are correct. Example problem
5672 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5673 long time.)
5674
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005675- Issue #1580: On most platforms, use a 'short' float repr: for a
5676 finite float x, repr(x) now outputs a string based on the shortest
5677 sequence of decimal digits that rounds to x. Previous behaviour was
5678 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005679 Another minor difference is that the new repr switches to
5680 exponential notation at 1e16 instead of the previous 1e17; this
5681 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005682
5683 There's a new sys attribute sys.float_repr_style, which takes
5684 the value 'short' to indicate that we're using short float repr,
5685 and 'legacy' if the short float repr isn't available for one
5686 reason or another.
5687
5688 The float repr change involves incorporating David Gay's 'perfect
5689 rounding' code into the Python core (it's in Python/dtoa.c). As a
5690 secondary consequence, all string-to-float and float-to-string
5691 conversions (including all float formatting operations) will be
5692 correctly rounded on these platforms.
5693
Georg Brandl5f90d792010-08-01 22:31:05 +00005694 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005695 this change does not apply.
5696
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005697- Issue #5759: float() didn't call __float__ on str subclasses.
5698
Georg Brandlabc38772009-04-12 15:51:51 +00005699- The string.maketrans() function is deprecated; there is a new static method
5700 maketrans() on the bytes and bytearray classes. This removes confusion about
5701 the types string.maketrans() is supposed to work with, and mirrors the
5702 methods available on the str class.
5703
R. David Murraydc6da8a2009-04-09 22:16:43 +00005704- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5705 its clarity and its speed.
5706
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005707- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005708 to avoid compiler warnings.
5709
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005710- Issue #3739: The unicode-internal encoder now reports the number of characters
5711 consumed like any other encoder (instead of the number of bytes).

Guido van Rossum0ad59d42009-03-30 22:01:35 +00005861- Issue #5604: non-ASCII characters in module name passed to
5862 imp.find_module() were converted to UTF-8 while the path is
5863 converted to the default filesystem encoding, causing nonsense.
5864
Benjamin Peterson09832742009-03-26 17:15:46 +00005865- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005867- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5868 the end sys.path, for compatibility with the system install of Python.
5869
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005870- Issue #4688: Add a heuristic so that tuples and dicts containing only
5871 untrackable objects are not tracked by the garbage collector. This can
5872 reduce the size of collections and therefore the garbage collection overhead
5873 on long-running programs, depending on their particular use of datatypes.
5874
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005875- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
5876 improve its performance. Long divisions and remainder operations
5877 are now between 50% and 150% faster.
5878
Mark Dickinsonbd792642009-03-18 20:06:12 +00005879- Issue #4258: Make it possible to use base 2**30 instead of base
5880 2**15 for the internal representation of integers, for performance
5881 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5882 --enable-big-digits option to configure, which overrides the
5883 default. Add sys.int_info structseq to provide information about
5884 the internal format.
5885
Mark Dickinson081dfee2009-03-18 14:47:41 +00005886- Issue #4474: PyUnicode_FromWideChar now converts characters outside
5887 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5888 and sizeof(Py_UNICODE) == 2.
5889
Eric Smith8ec90442009-03-14 12:29:34 +00005890- Issue #5237: Allow auto-numbered fields in str.format(). For
5891 example: '{} {}'.format(1, 2) == '1 2'.
5892
Antoine Pitrou652e7072009-03-13 19:25:20 +00005893- Issue #5392: when a very low recursion limit was set, the interpreter would
5894 abort with a fatal error after the recursion limit was hit twice.
5895
Matthias Klose042f1332009-04-04 14:32:42 +00005896- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

5985 used when using str.format() with str, int, and float arguments.
5986
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005987- Issue #5249: time.strftime returned malformed string when format string
5988 contained non ascii character on windows.
5989
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005990- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5991 source has already been decoded into str.
5992
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005993- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5994 rotating the object pointer by 4 bits to the right.
5995
Mark Dickinson87ec0852009-02-09 17:15:59 +00005996- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5997 it now forces its argument to double before testing for infinity.
5998
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005999- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6000 returns a non-number type.
6001
Benjamin Peterson87618552009-02-08 15:00:52 +00006002- Issue #5182: Removed memoryview.__str__.
6003
Mark Dickinsonc008a172009-02-01 13:59:22 +00006004- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6005 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006006 the type definition cmpfunc. The tp_compare slot has been renamed
6007 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006008
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006009- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006010 were suppressing all exceptions. These include list() and bytearray().
6011
Mark Dickinson1124e712009-01-28 21:25:58 +00006012- Issue #4707: round(x, n) now returns an integer if x is an integer.
6013 Previously it returned a float.
6014
Antoine Pitroub52ec782009-01-25 16:34:23 +00006015- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6016 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6017 evaluation loop is compiled with a new dispatch mechanism which gives
6018 speedups of up to 20%, depending on the system, on various benchmarks.
6019
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006020- Issue #4874: Most builtin decoders now reject unicode input.

6026
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00006027- Issue #4838: When a module is deallocated, free the memory backing the
6028 optional module state data.
6029
Mark Dickinson8055afd2009-01-17 10:04:45 +00006030- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006031 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006032
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006033- Issue #4935: The overflow checking code in the expandtabs() method common
6034 to str, bytes and bytearray could be optimized away by the compiler, letting
6035 the interpreter segfault instead of raising an error.
6036
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006037- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6038 __next__ method.
6039
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006040- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6041 function no longer attempt to call the __long__ slot to convert an object
6042 to an integer. Only the __int__ and __trunc__ slots are examined.
6043
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006044- Issue #4893: Use NT threading on CE.

6047
Antoine Pitrouab868312009-01-10 15:40:25 +00006048- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6049 common cases are optimized thanks to a dedicated fast path and a moderate
6050 amount of loop unrolling.
6051
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006052- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6053 collecting the oldest generation) so that allocating lots of objects without
6054 destroying them does not show quadratic performance. Based on a proposal by
6055 Martin von Löwis at
6056 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6057
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006058- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006059 having been closed (for instance, a read() call could return some
6060 previously buffered data). Patch by Dmitry Vasiliev.
6061
Antoine Pitrou05608432009-01-09 18:53:14 +00006062- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6063 flag to work properly. Furthermore, when specifying -u, the text stdout
6064 and stderr streams have line-by-line buffering enabled (the default being
6065 to buffer arbitrary chunks of data).
6066
Raymond Hettinger35631532009-01-09 03:58:09 +00006067- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6068 instead of ints (reducing its size from 4 to 8 times thereby reducing
6069 Python's overall memory).
6070
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006071- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6072 an existing .py counterpart, override the co_filename attributes of all
6073 code objects if the original filename is obsolete (which can happen if the
6074 file has been renamed, moved, or if it is accessed through different paths).
6075 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6076
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006077- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6078 one byte. Also fixes the meaning of len() so that it returns the number of
6079 items, rather than the size in bytes.
6080
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006081- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6082
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006083- Issue #4747: When the terminal does not use utf-8, executing a script with
6084 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6085
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006086- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6087 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006088
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006089- Issue #3680: Reference cycles created through a dict, set or deque iterator
6090 did not get collected.
6091
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006092- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6093 where the tp_hash and tp_dict slots are both NULL.
6094
Georg Brandlccc47b62008-12-28 11:44:14 +00006095- Issue #4759: None is now allowed as the first argument of
6096 bytearray.translate(). It was always allowed for bytes.translate().
6097
Skip Montanaro80072cb2008-12-23 03:51:14 +00006098- Added test case to ensure attempts to read from a file opened for writing
6099 fail.
6100
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006101- Issue #3106: Speedup some comparisons (str/str and int/int).

6104 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6105
Antoine Pitrou621601a2008-12-17 23:18:19 +00006106- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6107 print elapsed times, not only when some objects are uncollectable /
6108 unreachable. Original patch by Neil Schemenauer.
6109
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006110- Issue #3439: Add a bit_length method to int.
6111
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006112- Issue #2173: When getting device encoding, check that return value of
6113 nl_langinfo is not the empty string. This was causing silent build
6114 failures on OS X.
6115
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006116- Issue #4597: Fixed several opcodes that weren't always propagating
6117 exceptions.
6118
6119- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006120 context manager returns a value that cannot be converted to a bool.
6121
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006122- Issue #4445: Replace "sizeof(PyBytesObject)" with
6123 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6124 bytes instances. On a typical machine this saves 3 bytes of memory
6125 (on average) per allocation of a bytes instance.
6126
Christian Heimesa872de52008-12-05 08:26:55 +00006127- Issue #4533: File read operation was dreadfully slow due to a slowly
6128 growing read buffer. Fixed by using the same growth rate algorithm as
6129 Python 2.x.
6130
Antoine Pitrou5504e892008-12-06 21:27:53 +00006131- Issue #4509: Various issues surrounding resize of bytearray objects to
6132 which there are buffer exports (e.g. memoryview instances).
6133
Georg Brandlf9734072008-12-07 15:30:06 +00006134- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6135 method on file objects with closefd=False. The file descriptor is still
6136 kept open but the file object behaves like a closed file. The ``FileIO``
6137 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006138
Antoine Pitroubc420402008-12-07 20:14:49 +00006139- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6140 larger than 1.

Antoine Pitrou08838b62009-01-21 00:55:13 +00006469- Issue #5008: When a file is opened in append mode with the new IO library,
6470 do an explicit seek to the end of file (so that e.g. tell() returns the
6471 file size rather than 0). This is consistent with the behaviour of the

6502 appropriately when it is being used via socket.makefile() objects
6503 rather than delaying the close by waiting for garbage collection to do it.
6504
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006505- Issue #1696199: Add collections.Counter() for rapid and convenient

6717 supporting objects as input no matter how it was compiled (built in
6718 implementations or external openssl library).
6719
Mark Dickinson29500f62009-01-15 15:36:10 +00006720- Issue #4397: Fix occasional test_socket failure on OS X.

6723
Antoine Pitroubcd5cbe2009-01-08 21:17:16 +00006724- Issue #4751: hashlib now releases the GIL when hashing large buffers
6725 (with a hardwired threshold of 2048 bytes), allowing better parallelization
6726 on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.
6727
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006728- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
6729
Antoine Pitrou31f30b12009-01-02 17:34:35 +00006730- Issue #4738: Each zlib object now has a separate lock, allowing to compress
6731 or decompress several streams at once on multi-CPU systems. Also, the GIL
6732 is now released when computing the CRC of a large buffer. Patch by ebfe.
6733
Georg Brandlb1441c72009-01-03 22:33:39 +00006734- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.

6739 OpenBSD.
Amaury Forgeot d'Arcefae8c42008-11-21 23:08:09 +00006740
Antoine Pitrou3ad3a0d2008-12-18 17:08:32 +00006741- Issue #4583: array.array would not always prohibit resizing when a buffer
6742 has been exported, resulting in an interpreter crash when accessing the
6743 buffer.
6744
Martin v. Löwis841edad2008-11-30 10:36:49 +00006745
Jack Diederiche0cbd692009-04-01 04:27:09 +00006746- Issue #5228: Make functools.partial objects can now be pickled.

6749-----
6750
Antoine Pitrou88909542009-06-29 13:54:42 +00006751- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6752 regression tests in parallel, shortening the total runtime.
6753
Guilherme Polo2a998fa2009-06-21 17:40:07 +00006754- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6755 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6756 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6757 skip the tests if DISPLAY is defined but can't be used.
6758
R. David Murraya21e4ca2009-03-31 23:16:50 +00006759- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006760 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006761 from test support, which does the conversion.
6762
Guilherme Polo9de29af2009-01-28 20:40:48 +00006763- Issue #5083: New 'gui' resource for regrtest.
