Ned Deily657b2de2011-06-28 19:51:30 -0700493- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to

496 and was unreliable since tests or user programs could modify the interpreter
497 environment after Distutils set it. Instead, have Distutils set the the
498 deployment target only in the environment of each build subprocess. It is
499 still possible to globally override the default by setting
500 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
501 greater or equal to the default value, the value with which the interpreter
502 was built.

R. David Murrayb7deff12011-01-30 06:21:28 +00001175- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
1176 files in binary mode, using the email package's binary support to parse
1177 arbitrary email messages. StringIO and text file input is deprecated,
1178 and string input fails early if non-ASCII characters are used, where
1179 previously it would fail when the email was processed in a later step.
1180
Nick Coghlan793ee1f2011-01-30 01:24:08 +00001181- Issue #10845: Mitigate the incompatibility between the multiprocessing

Ned Deily806c9442011-01-29 18:43:56 +00001190- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
1191 preventing a confusing hung appearance on OS X with the windows
1192 obscured.
1193
Ned Deily70063932011-01-29 18:29:01 +00001194- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the

1204 with a None body.
1205
Raymond Hettingera63a3122011-01-26 20:34:14 +00001206- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
1207 keyword-only argument. The preceding positional argument was deprecated,
1208 so it made no sense to add filter as a positional argument.
1209
Raymond Hettinger512d2cc2011-01-25 21:32:39 +00001210- Issue #11004: Repaired edge case in deque.count().
1211
Ned Deily122539e2011-01-24 21:46:44 +00001212- Issue #10974: IDLE no longer crashes if its recent files list includes files
1213 with non-ASCII characters in their path names.

Victor Stinnerf2e439f2011-01-23 00:11:58 +00001222- Issue #10955: zipimport uses ASCII encoding instead of cp437 to decode
Victor Stinner4ee65a92011-01-22 10:30:29 +00001223 filenames, at bootstrap, if the codec registry is not ready yet. It is still
1224 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +00001225 for all file entries in the ZIP file.
Victor Stinner4ee65a92011-01-22 10:30:29 +00001226

1233 a symbol named FSTAT.
1234
Armin Ronacher8d96d772011-01-22 13:13:05 +00001235- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1236 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1237 of HTTP 1.1.
1238
Armin Ronacher59531282011-01-22 13:44:22 +00001239- To match the behaviour of HTTP server, the HTTP client library now also
1240 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1241 that for incoming headers which makes this behaviour now consistent in
1242 both incoming and outgoing direction.
1243
Steven Bethardb0270112011-01-24 21:02:50 +00001244- Issue #9509: argparse now properly handles IOErrors raised by

1248 during request handling.
1249
Georg Brandl0f6b47a2011-01-30 12:19:35 +00001250- Issue #10680: Fix mutually exclusive arguments for argument groups in
1251 argparse.

Georg Brandl255abdd2011-01-16 14:17:26 +00001278- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
1279 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
1280 translates newlines (\r\n => \n).

Martin v. Löwisc83bc3c2011-01-06 19:15:47 +00001282- Remove buffer API from stable ABI for now, see #10181.

1345 is made for all headers in any serialized message at serialization time. This
1346 provides protection against header injection attacks.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00001999 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002000 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002001 encoding and to encode command line arguments on this OS.

2394 with a non-empty format string. This is an effort to future-proof user
2395 code. If a derived class does not currently implement __format__ but later
2396 adds its own __format__, it would most likely break user code that had
2397 supplied a format string. This will be changed to a DeprecationWaring in
2398 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002400- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

2402 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

2405 functions from the libc caused the methods .upper() and lower() to become
2406 locale aware and created subtly wrong results.
2407

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002411- Issue #4617: Previously it was illegal to delete a name from the local
2412 namespace if it occurs as a free variable in a nested block. This limitation
2413 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2414
Georg Brandl27a28582010-10-10 09:49:21 +00002415- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2416 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2417 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2418 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002453- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002454 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002455 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002456 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002481 retry the select() loop instead of bailing out. This is because select() can
2482 incorrectly report a socket as ready for reading (for example, if it received
2483 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002563- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002564 it possible for the user to create self-referencing ordered dictionaries which
2565 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002566 approach of using weakref proxies so that reference cycles never get created
2567 in the first place.
2568
Victor Stinnercb043522010-09-10 23:49:04 +00002569- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002573- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2574 environment variable to set the filesystem encoding at Python startup.
2575 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2576 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002582- The pprint module now supports printing OrderedDicts in their given order

2587
Georg Brandl27a28582010-10-10 09:49:21 +00002588- Issue #9707: Rewritten reference implementation of threading.local which is
2589 friendlier towards reference cycles. This change is not normally visible
2590 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002592- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2593 still return the id of the parent process after it has exited. This process
2594 id may even have been reused by another unrelated process.
2595
Georg Brandl27a28582010-10-10 09:49:21 +00002596- Issue #9792: In case of connection failure, socket.create_connection() would
2597 swallow the exception and raise a new one, making it impossible to fetch the
2598 original errno, or to filter timeout errors. Now the original error is
2599 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002605- Updates to the random module:
2606
Georg Brandl27a28582010-10-10 09:49:21 +00002607 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002610 * Update the seed() method to use all of the bits in a string instead of just
2611 the hash value. This makes better use of the seed value and assures the
2612 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002613
Georg Brandl27a28582010-10-10 09:49:21 +00002614 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2615 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2616 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002617
2618 * Improved documentation of arguments to randrange(). Issue #9379.

2639 guaranteed to exist in all Python implementations and the names of hash
2640 algorithms available in the current process.

2769 return characters from the full Unicode range, even on narrow unicode builds
2770 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2771 in Python is that unicodedata.numeric() now returns the correct value for
2772 large code points, and repr() may consider more characters as printable.
2773
Victor Stinner6c00c142010-08-17 23:37:11 +00002774- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Victor Stinner47fcb5b2010-08-13 23:59:58 +00002790- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00002791 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2792 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00002798- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2799 use PyUnicode_FromFormatV() to format the warning message.

2807 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002808
Georg Brandl649971e2010-09-05 17:06:50 +00002809- Issue #9416: Fix some issues with complex formatting where the output with no
2810 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002811
2812 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2813 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3151
Ezio Melotti57221d02010-07-01 07:32:02 +00003152- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003153 start byte and the continuation byte(s) are now considered invalid, instead of
3154 the number of bytes specified by the start byte. E.g.:
3155 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3156 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3157 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3158 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00003159
Georg Brandl62069d32010-07-31 08:56:11 +00003160- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
3161 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00003162
Benjamin Peterson88968ad2010-06-25 19:30:21 +00003163- Be more specific in error messages about positional arguments.

Georg Brandl62069d32010-07-31 08:56:11 +00003172- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3173 dealing with unary minus applied to a constant. The removed code was mutating
3174 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003175
Victor Stinner554f3f02010-06-16 23:33:54 +00003176- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003177 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003178 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003179 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003180
Victor Stinner25e8ec42010-06-25 00:02:38 +00003181- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use

3183
Victor Stinner06e49dd2010-06-13 18:21:50 +00003184- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003185 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003186 string formats.
3187
Georg Brandl62069d32010-07-31 08:56:11 +00003188- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003189 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3190 location of the raised exception.
3191
Victor Stinner313a1202010-06-11 23:56:51 +00003192- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3193 filenames and enable os.fsencode().
3194
Benjamin Peterson285a6892010-06-22 19:21:52 +00003195- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3196
Georg Brandl62069d32010-07-31 08:56:11 +00003197- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3198 interpreter with characters outside the Basic Multilingual Plane (higher than
3199 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003200
Georg Brandl62069d32010-07-31 08:56:11 +00003201- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3202 TypeError instead of giving a DeprecationWarning when a float is parsed using
3203 the 'L' code (for long long). (All other integer codes already raise
3204 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003205
Victor Stinner600d3be2010-06-10 12:00:55 +00003206- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3207 enable shortcuts for upper case encoding name. Add also a shortcut for
3208 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3209
Georg Brandl62069d32010-07-31 08:56:11 +00003210- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3211 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003212
3213- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003214 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003215 like bytearray.
3216
Georg Brandl62069d32010-07-31 08:56:11 +00003217- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003218 used anymore and it was never documented.
3219
Georg Brandl62069d32010-07-31 08:56:11 +00003220- In str.format(), raise a ValueError when indexes to arguments are too large.

3223 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003224
Georg Brandl62069d32010-07-31 08:56:11 +00003225- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3226 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3227 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3228 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003229
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003230- Issue #8748: Fix two issues with comparisons between complex and integer
3231 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003232 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3233 (2) The comparison raised an OverflowError for large integers, leading to
3234 unpredictable exceptions when combining integers and complex objects in sets
3235 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003236

3239
Victor Stinner9ca9c252010-05-19 16:53:30 +00003240- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003241 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003242 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003243
Georg Brandl62069d32010-07-31 08:56:11 +00003244- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3245 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003246
Victor Stinnerae6265f2010-05-15 16:27:27 +00003247- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3248 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003249 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003250 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003251
Victor Stinner59e62db2010-05-15 13:14:32 +00003252- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003253 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003254
Victor Stinnerb744ba12010-05-15 12:27:16 +00003255- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003256 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003257 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3258
Victor Stinner0964ee12010-04-30 16:48:45 +00003259- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003260 PyUnicode_FromString() to support surrogates in the filename and use the right
3261 encoding.

3362 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003364- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003365 where the right hand operand is a set of constants, by turning the set into a
3366 frozenset and pre-building it as a constant. The comparison operation is made
3367 against the constant instead of building a new set each time it is executed (a
3368 similar optimization already existed which turned a list of constants into a
3369 pre-built tuple). Patch and additional tests by Dave Malcolm.

3376 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3377 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3378 parsing certain long numeric strings corresponding to subnormal values, (3) a
3379 memory leak for some values large enough to cause overflow, and (4) a number
3380 of flaws that could lead to incorrectly rounded results.

3396 least on IEEE 754 platforms), and in particular does not depend on the
3397 internal representation of an int.

3675 the performance hit anytime the cache is exceeded.

R. David Murrayb2416e52010-04-12 16:58:02 +00004055- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004056 filename and date, conforming to the 'standards' they were originally designed
4057 to follow. This improves compatibility with patch tools.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004073- Add functools.total_ordering() and functools.cmp_to_key().
4074
Georg Brandl62069d32010-07-31 08:56:11 +00004075- Issue #8257: The Decimal construct now accepts a float instance directly,
4076 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004077
4078 >>> Decimal(1.1)
4079 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004084- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4085 InvalidOperation instead of returning False. (Comparisons involving a quiet
4086 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4087 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004088
Georg Brandl62069d32010-07-31 08:56:11 +00004089- Issue #2531: Comparison operations between floats and Decimal instances now
4090 return a result based on the numeric values of the operands; previously they
4091 returned an arbitrary result based on the relative ordering of id(float) and
4092 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4093 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004094
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004095- Added a subtract() method to collections.Counter().
4096
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004097- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004098 argument `-` which tells it to read files to compile from stdin. Each line is
4099 read on demand and the named file is compiled immediately. (Original patch by
4100 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004102- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004106- Comparisons using one of <, <=, >, >= between a complex instance and a
4107 Fractions instance now raise TypeError instead of returning True/False. This
4108 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4109 <=> complex, and complex <=> complex comparisons.

4117
Antoine Pitrou910bd512010-03-22 20:11:09 +00004118- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004119 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00004152- The internals of the subprocess module on POSIX systems have been replaced by
4153 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4154 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004155
Georg Brandl62069d32010-07-31 08:56:11 +00004156- subprocess.Popen now has restore_signals and start_new_session features. The
4157 default of restore_signals=True is a new behavior compared to earlier Python
4158 versions. This means that signals such as SIGPIPE are not ignored by default
4159 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00004160

4246 position when calling `truncate()`. It would previously change the file
4247 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004248 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4252 archive. The new implementation is significantly faster and can be wrapped in
4253 a :class:`io.BufferedReader` object for more speedups. It also solves an
4254 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004652- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004653 compared to other unix systems. In particular, os.getgroups() does not reflect
4654 any changes made using os.setgroups() but basicly always returns the same

Brett Cannoncfed0292009-11-05 01:26:57 +00005002- Issue #7248 (part 2): Use a unique temporary directory for importlib source
5003 tests instead of tempfile.tempdir. This prevents the tests from sharing state
5004 between concurrent executions on the same system.

5012 threads could return successfully while some Thread objects were still
5013 referenced. This also introduces a new private function:

5021
R. David Murray0bc11ae2009-10-18 22:18:17 +00005022- Issue #7058: Added save/restore for things like sys.argv and cwd to
Georg Brandl62069d32010-07-31 08:56:11 +00005023 runtest_inner in regrtest, with warnings if the called test modifies them, and

5297================================
5298
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005299*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005300
5301Core and Builtins
5302-----------------
5303
Mark Dickinson865e01a2009-05-07 16:37:01 +00005304- Issue #5914: Add new C API function PyOS_string_to_double, and
5305 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5306
Eric Smith741191f2009-05-06 13:08:15 +00005307- Issue #3382: float.__format__, complex.__format__, and %-formatting
5308 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5309 affects nan -> NAN and inf -> INF.
5310
Mark Hammond5a607a32009-05-06 08:04:54 +00005311- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5312 in all operations, including splitdrive, split, etc. splitunc() now issues
5313 a PendingDeprecation warning.
5314
Eric Smith63376222009-05-05 14:04:18 +00005315- Issue #5920: For float.__format__, change the behavior with the
5316 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5317 to be like 'g' but with at least one decimal point and with a
5318 default precision of 12. Previously, the behavior the same but with
5319 a default precision of 6. This more closely matches str(), and
5320 reduces surprises when adding alignment flags to the empty
5321 presentation type. This also affects the new complex.__format__ in
5322 the same way.
5323
Martin v. Löwis011e8422009-05-05 04:43:17 +00005324- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5325
R. David Murrayb18500d2009-05-04 22:59:07 +00005326- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5327 shadowed by classtype's, even if it was None. property now
5328 inserts the __doc__ into the subclass instance __dict__.
5329
Antoine Pitrou244651a2009-05-04 18:56:13 +00005330- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5331 sequences. Patch by Nick Barnes and Victor Stinner.
5332
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005333- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005334
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005335- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5336 received a new method, detach(). detach() disconnects the underlying stream
5337 from the buffer or text IO and returns it.
5338
Mark Dickinson33841c32009-05-01 15:37:04 +00005339- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5340 floats with absolute value over 1e50. Also remove length
5341 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5342 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005343
Eric Smith741191f2009-05-06 13:08:15 +00005344- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005345 format(complex(1, 2./3), '.5') now produces a sensible result.
5346
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005347- Issue #5864: Fix empty format code formatting for floats so that it
5348 never gives more than the requested number of significant digits.
5349
Eric Smith6dc46f52009-04-27 20:39:49 +00005350- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5351 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5352
Eric Smithcc32a112009-04-26 21:35:14 +00005353- Issue #5835: Deprecate PyOS_ascii_formatd.
5354
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005355- Issue #4971: Fix titlecase for characters that are their own
5356 titlecase, but not their own uppercase.
5357
Benjamin Peterson193152c2009-04-25 01:08:45 +00005358- Issue #5283: Setting __class__ in __del__ caused a segfault.
5359
Mark Dickinsonad476da2009-04-23 19:14:16 +00005360- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5361 z involves nans, infs or negative zeros.
5362
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005363- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005364
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005365- Issue #1869 (and many duplicates): make round(x, n) correctly
5366 rounded for a float x, by using the decimal <-> binary conversions
5367 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5368 consistently agrees with format(x, '.2f').
5369
Benjamin Petersonae937c02009-04-18 20:54:08 +00005370- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5371 some builtin types.
5372
Eric Smith0923d1d2009-04-16 20:16:10 +00005373- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5374
Eric Smith35e84722009-04-16 20:21:28 +00005375- Issue #5515: str.format() type 'n' combined with commas and leading
5376 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005377
5378- Implement PEP 378, Format Specifier for Thousands Separator, for
5379 floats.
5380
Mark Dickinson3370cce2009-04-17 22:40:53 +00005381- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005382 1e11, not 1e12. This avoids printing 13 significant digits in
5383 situations where only 12 of them are correct. Example problem
5384 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5385 long time.)
5386
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005387- Issue #1580: On most platforms, use a 'short' float repr: for a
5388 finite float x, repr(x) now outputs a string based on the shortest
5389 sequence of decimal digits that rounds to x. Previous behaviour was
5390 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005391 Another minor difference is that the new repr switches to
5392 exponential notation at 1e16 instead of the previous 1e17; this
5393 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005394
5395 There's a new sys attribute sys.float_repr_style, which takes
5396 the value 'short' to indicate that we're using short float repr,
5397 and 'legacy' if the short float repr isn't available for one
5398 reason or another.
5399
5400 The float repr change involves incorporating David Gay's 'perfect
5401 rounding' code into the Python core (it's in Python/dtoa.c). As a
5402 secondary consequence, all string-to-float and float-to-string
5403 conversions (including all float formatting operations) will be
5404 correctly rounded on these platforms.
5405
Georg Brandl5f90d792010-08-01 22:31:05 +00005406 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005407 this change does not apply.
5408
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005409- Issue #5759: float() didn't call __float__ on str subclasses.
5410
Georg Brandlabc38772009-04-12 15:51:51 +00005411- The string.maketrans() function is deprecated; there is a new static method
5412 maketrans() on the bytes and bytearray classes. This removes confusion about
5413 the types string.maketrans() is supposed to work with, and mirrors the
5414 methods available on the str class.
5415
R. David Murraydc6da8a2009-04-09 22:16:43 +00005416- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5417 its clarity and its speed.
5418
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005419- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005420 to avoid compiler warnings.
5421
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005422- Issue #3739: The unicode-internal encoder now reports the number of characters
5423 consumed like any other encoder (instead of the number of bytes).

5437
Raymond Hettingereb816952009-05-29 01:22:18 +00005438- Issue #5150: IDLE's format menu now has an option to strip trailing

Guido van Rossum0ad59d42009-03-30 22:01:35 +00005573- Issue #5604: non-ASCII characters in module name passed to
5574 imp.find_module() were converted to UTF-8 while the path is
5575 converted to the default filesystem encoding, causing nonsense.
5576
Benjamin Peterson09832742009-03-26 17:15:46 +00005577- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005579- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5580 the end sys.path, for compatibility with the system install of Python.
5581
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005582- Issue #4688: Add a heuristic so that tuples and dicts containing only
5583 untrackable objects are not tracked by the garbage collector. This can
5584 reduce the size of collections and therefore the garbage collection overhead
5585 on long-running programs, depending on their particular use of datatypes.
5586
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005587- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
5588 improve its performance. Long divisions and remainder operations
5589 are now between 50% and 150% faster.
5590
Mark Dickinsonbd792642009-03-18 20:06:12 +00005591- Issue #4258: Make it possible to use base 2**30 instead of base
5592 2**15 for the internal representation of integers, for performance
5593 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5594 --enable-big-digits option to configure, which overrides the
5595 default. Add sys.int_info structseq to provide information about
5596 the internal format.
5597
Mark Dickinson081dfee2009-03-18 14:47:41 +00005598- Issue #4474: PyUnicode_FromWideChar now converts characters outside
5599 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5600 and sizeof(Py_UNICODE) == 2.
5601
Eric Smith8ec90442009-03-14 12:29:34 +00005602- Issue #5237: Allow auto-numbered fields in str.format(). For
5603 example: '{} {}'.format(1, 2) == '1 2'.
5604
Antoine Pitrou652e7072009-03-13 19:25:20 +00005605- Issue #5392: when a very low recursion limit was set, the interpreter would
5606 abort with a fatal error after the recursion limit was hit twice.
5607
Matthias Klose042f1332009-04-04 14:32:42 +00005608- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
5609 short file names.

5654
Lars Gustäbel42e00912009-03-22 20:34:29 +00005655- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5656 forever on incomplete input. That caused tarfile.open() to hang when used
5657 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

5697 used when using str.format() with str, int, and float arguments.
5698
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005699- Issue #5249: time.strftime returned malformed string when format string
5700 contained non ascii character on windows.
5701
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005702- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5703 source has already been decoded into str.
5704
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005705- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5706 rotating the object pointer by 4 bits to the right.
5707
Mark Dickinson87ec0852009-02-09 17:15:59 +00005708- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5709 it now forces its argument to double before testing for infinity.
5710
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005711- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5712 returns a non-number type.
5713
Benjamin Peterson87618552009-02-08 15:00:52 +00005714- Issue #5182: Removed memoryview.__str__.
5715
Mark Dickinsonc008a172009-02-01 13:59:22 +00005716- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5717 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005718 the type definition cmpfunc. The tp_compare slot has been renamed
5719 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005720
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005721- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005722 were suppressing all exceptions. These include list() and bytearray().
5723
Mark Dickinson1124e712009-01-28 21:25:58 +00005724- Issue #4707: round(x, n) now returns an integer if x is an integer.
5725 Previously it returned a float.
5726
Antoine Pitroub52ec782009-01-25 16:34:23 +00005727- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5728 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5729 evaluation loop is compiled with a new dispatch mechanism which gives
5730 speedups of up to 20%, depending on the system, on various benchmarks.
5731
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005732- Issue #4874: Most builtin decoders now reject unicode input.

5738
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005739- Issue #4838: When a module is deallocated, free the memory backing the
5740 optional module state data.
5741
Mark Dickinson8055afd2009-01-17 10:04:45 +00005742- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005743 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005744
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005745- Issue #4935: The overflow checking code in the expandtabs() method common
5746 to str, bytes and bytearray could be optimized away by the compiler, letting
5747 the interpreter segfault instead of raising an error.
5748
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005749- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5750 __next__ method.
5751
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005752- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5753 function no longer attempt to call the __long__ slot to convert an object
5754 to an integer. Only the __int__ and __trunc__ slots are examined.
5755
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005756- Issue #4893: Use NT threading on CE.

5759
Antoine Pitrouab868312009-01-10 15:40:25 +00005760- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5761 common cases are optimized thanks to a dedicated fast path and a moderate
5762 amount of loop unrolling.
5763
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005764- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5765 collecting the oldest generation) so that allocating lots of objects without
5766 destroying them does not show quadratic performance. Based on a proposal by
5767 Martin von Löwis at
5768 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5769
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005770- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005771 having been closed (for instance, a read() call could return some
5772 previously buffered data). Patch by Dmitry Vasiliev.
5773
Antoine Pitrou05608432009-01-09 18:53:14 +00005774- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5775 flag to work properly. Furthermore, when specifying -u, the text stdout
5776 and stderr streams have line-by-line buffering enabled (the default being
5777 to buffer arbitrary chunks of data).
5778
Raymond Hettinger35631532009-01-09 03:58:09 +00005779- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5780 instead of ints (reducing its size from 4 to 8 times thereby reducing
5781 Python's overall memory).
5782
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005783- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5784 an existing .py counterpart, override the co_filename attributes of all
5785 code objects if the original filename is obsolete (which can happen if the
5786 file has been renamed, moved, or if it is accessed through different paths).
5787 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5788
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005789- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5790 one byte. Also fixes the meaning of len() so that it returns the number of
5791 items, rather than the size in bytes.
5792
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005793- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5794
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005795- Issue #4747: When the terminal does not use utf-8, executing a script with
5796 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5797
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005798- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5799 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005800
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005801- Issue #3680: Reference cycles created through a dict, set or deque iterator
5802 did not get collected.
5803
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005804- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5805 where the tp_hash and tp_dict slots are both NULL.
5806
Georg Brandlccc47b62008-12-28 11:44:14 +00005807- Issue #4759: None is now allowed as the first argument of
5808 bytearray.translate(). It was always allowed for bytes.translate().
5809
Skip Montanaro80072cb2008-12-23 03:51:14 +00005810- Added test case to ensure attempts to read from a file opened for writing
5811 fail.
5812
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005813- Issue #3106: Speedup some comparisons (str/str and int/int).

5816 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5817
Antoine Pitrou621601a2008-12-17 23:18:19 +00005818- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5819 print elapsed times, not only when some objects are uncollectable /
5820 unreachable. Original patch by Neil Schemenauer.
5821
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005822- Issue #3439: Add a bit_length method to int.
5823
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005824- Issue #2173: When getting device encoding, check that return value of
5825 nl_langinfo is not the empty string. This was causing silent build
5826 failures on OS X.
5827
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005828- Issue #4597: Fixed several opcodes that weren't always propagating
5829 exceptions.
5830
5831- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005832 context manager returns a value that cannot be converted to a bool.
5833
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005834- Issue #4445: Replace "sizeof(PyBytesObject)" with
5835 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5836 bytes instances. On a typical machine this saves 3 bytes of memory
5837 (on average) per allocation of a bytes instance.
5838
Christian Heimesa872de52008-12-05 08:26:55 +00005839- Issue #4533: File read operation was dreadfully slow due to a slowly
5840 growing read buffer. Fixed by using the same growth rate algorithm as
5841 Python 2.x.
5842
Antoine Pitrou5504e892008-12-06 21:27:53 +00005843- Issue #4509: Various issues surrounding resize of bytearray objects to
5844 which there are buffer exports (e.g. memoryview instances).
5845
Georg Brandlf9734072008-12-07 15:30:06 +00005846- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5847 method on file objects with closefd=False. The file descriptor is still
5848 kept open but the file object behaves like a closed file. The ``FileIO``
5849 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005850
Antoine Pitroubc420402008-12-07 20:14:49 +00005851- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5852 larger than 1.

Antoine Pitrou08838b62009-01-21 00:55:13 +00006181- Issue #5008: When a file is opened in append mode with the new IO library,
6182 do an explicit seek to the end of file (so that e.g. tell() returns the
6183 file size rather than 0). This is consistent with the behaviour of the

6214 appropriately when it is being used via socket.makefile() objects
6215 rather than delaying the close by waiting for garbage collection to do it.
6216
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006217- Issue #1696199: Add collections.Counter() for rapid and convenient

6429 supporting objects as input no matter how it was compiled (built in
6430 implementations or external openssl library).
6431
Mark Dickinson29500f62009-01-15 15:36:10 +00006432- Issue #4397: Fix occasional test_socket failure on OS X.

6435
Antoine Pitroubcd5cbe2009-01-08 21:17:16 +00006436- Issue #4751: hashlib now releases the GIL when hashing large buffers
6437 (with a hardwired threshold of 2048 bytes), allowing better parallelization
6438 on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.
6439
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006440- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
6441
Antoine Pitrou31f30b12009-01-02 17:34:35 +00006442- Issue #4738: Each zlib object now has a separate lock, allowing to compress
6443 or decompress several streams at once on multi-CPU systems. Also, the GIL
6444 is now released when computing the CRC of a large buffer. Patch by ebfe.
6445
Georg Brandlb1441c72009-01-03 22:33:39 +00006446- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.

6451 OpenBSD.
Amaury Forgeot d'Arcefae8c42008-11-21 23:08:09 +00006452
Antoine Pitrou3ad3a0d2008-12-18 17:08:32 +00006453- Issue #4583: array.array would not always prohibit resizing when a buffer
6454 has been exported, resulting in an interpreter crash when accessing the
6455 buffer.
6456
Martin v. Löwis841edad2008-11-30 10:36:49 +00006457
Jack Diederiche0cbd692009-04-01 04:27:09 +00006458- Issue #5228: Make functools.partial objects can now be pickled.

6461-----
6462
Antoine Pitrou88909542009-06-29 13:54:42 +00006463- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6464 regression tests in parallel, shortening the total runtime.
6465
Guilherme Polo2a998fa2009-06-21 17:40:07 +00006466- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6467 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6468 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6469 skip the tests if DISPLAY is defined but can't be used.
6470
R. David Murraya21e4ca2009-03-31 23:16:50 +00006471- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006472 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006473 from test support, which does the conversion.
6474
Guilherme Polo9de29af2009-01-28 20:40:48 +00006475- Issue #5083: New 'gui' resource for regrtest.
