16 compiling them.
17
Raymond Hettinger66d2be82011-07-28 09:55:13 -070018- Issue #12647: The None object now has a __bool__() method that returns False.
19 Formerly, bool(None) returned False only because of special case logic
20 in PyObject_IsTrue().
21
Eric V. Smith12ebefc2011-07-18 14:03:41 -040022- Issue #12579: str.format_map() now raises a ValueError if used on a

Antoine Pitrou84f1b172011-07-12 21:57:15 +020031- Issue #12149: Update the method cache after a type's dictionnary gets
32 cleared by the garbage collector. This fixes a segfault when an instance
33 and its type get caught in a reference cycle, and the instance's
34 deallocator calls one of the methods on the type (e.g. when subclassing
35 IOBase). Diagnosis and patch by Davide Rizzo.

41
Victor Stinnerd64e8a72011-07-04 13:48:30 +020042- Issue #9642: Fix filesystem encoding initialization: use the ANSI code page
43 on Windows if the mbcs codec is not available, and fail with a fatal error if
44 we cannot get the locale encoding (if nl_langinfo(CODESET) is not available)
45 instead of using UTF-8.
46

67 sequence, which will be converted to a list and sorted by dir().
68
Benjamin Petersonb204a422011-06-05 22:04:07 -050069- Issue #12265: Make error messages produced by passing an invalid set of

Ned Deily657b2de2011-06-28 19:51:30 -0700404- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
405 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
406 interpreter process. This could cause failures in non-Distutils subprocesses
407 and was unreliable since tests or user programs could modify the interpreter
408 environment after Distutils set it. Instead, have Distutils set the the
409 deployment target only in the environment of each build subprocess. It is
410 still possible to globally override the default by setting
411 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
412 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700413 was built. Also, implement the same handling in packaging.

Steven Bethardb0270112011-01-24 21:02:50 +00001467
1468- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00001469 encodes headers with iso-8859-1 (latin1) encoding. It was already doing

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001567- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001568 continuation line in the formatted value has no leading white space and looks
1569 like a header. Since Generator uses Header to format all headers, this check
1570 is made for all headers in any serialized message at serialization time. This
1571 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001572

Georg Brandl255abdd2011-01-16 14:17:26 +00001581 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001582
Éric Araujof0ab5d62011-05-29 03:43:59 +02001583- email.header.Header was incorrectly encoding folding whitespace when

1585 folding whitespace. It now uses the continuation_ws, as it does for

1591 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1592 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1593 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

2199-----------------
2200
Antoine Pitroucf9f9802010-11-10 13:55:25 +00002201- Issue #10372: Import the warnings module only after the IO library is
2202 initialized, so as to avoid bootstrap issues with the '-W' option.
2203
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002204- Issue #10293: Remove obsolete field in the PyMemoryView structure, unused
2205 undocumented value PyBUF_SHADOW, and strangely-looking code in
Antoine Pitrouaeb6cee2010-11-04 20:30:33 +00002206 PyMemoryView_GetContiguous.
2207
Georg Brandl54445ad2010-11-20 10:24:34 +00002208- Issue #6081: Add str.format_map(), similar to ``str.format(**mapping)``.
Eric Smith27bbca62010-11-04 17:06:58 +00002209
Benjamin Petersonbbb04122010-10-30 23:16:28 +00002210- If FileIO.__init__ fails, close the file descriptor.
2211
Raymond Hettingerdd421542010-10-30 08:10:29 +00002212- Issue #10221: dict.pop(k) now has a key error message that includes the
2213 missing key (same message d[k] returns for missing keys).
2214
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002215- Issue #5437: A preallocated MemoryError instance should not keep traceback
Antoine Pitrou07e20ef2010-10-28 22:56:58 +00002216 data (including local variables caught in the stack trace) alive infinitely.
2217
Benjamin Peterson503d6c52010-10-24 02:52:05 +00002218- Issue #10186: Fix the SyntaxError caret when the offset is equal to the length
2219 of the offending line.
2220
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002221- Issue #10089: Add support for arbitrary -X options on the command line. They

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002224- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2225 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002226 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002227 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002228 encoding and to encode command line arguments on this OS.
2229
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002230- Issue #9713, #10114: Parser functions (e.g. PyParser_ASTFromFile) expect
2231 filenames encoded to the filesystem encoding with the surrogateescape error
Victor Stinner4c7c8c32010-10-16 13:14:10 +00002232 handler (to support undecodable bytes), instead of UTF-8 in strict mode.
2233
Benjamin Peterson230b2062010-10-16 03:45:45 +00002234- Issue #9997: Don't let the name "top" have special significance in scope
2235 resolution.
2236
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002237- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding its value as
2238 the default 512 when compiling on AIX.
R. David Murraye16cda92010-10-15 23:12:57 +00002239
Victor Stinnerf3170cc2010-10-15 12:04:23 +00002240- Use locale encoding instead of UTF-8 to encode and decode filenames if

2242
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002243- Issue #10095: fp_setreadl() doesn't reopen the file, instead reuse the file
Victor Stinner22a351a2010-10-14 12:04:34 +00002244 descriptor.
2245
Georg Brandl66c221e2010-10-14 07:04:07 +00002246- Issue #9418: Moved private string methods ``_formatter_parser`` and

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002271- Issue #10386: Add __all__ to token module; this simplifies importing in

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002280 unexpectedly if the return value of a task could not be pickled. Only the
2281 ``repr`` of such errors are now sent back, wrapped in an
Ask Soleme912f5a2010-11-09 21:14:53 +00002282 ``MaybeEncodingError`` exception.
2283
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002284- Issue #9244: The ``apply_async()`` and ``map_async()`` methods of
2285 ``multiprocessing.Pool`` now accepts a ``error_callback`` argument. This can

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002341 incorrectly validated some non-compliant applications as WSGI compliant; if
2342 your app validates with Python <3.2b1+, but not on this version, it is likely

2621 with a non-empty format string. This is an effort to future-proof user
2622 code. If a derived class does not currently implement __format__ but later
2623 adds its own __format__, it would most likely break user code that had
2624 supplied a format string. This will be changed to a DeprecationWaring in
2625 Python 3.3 and it will be an error in Python 3.4.

2639 namespace if it occurs as a free variable in a nested block. This limitation
2640 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2641
Georg Brandl27a28582010-10-10 09:49:21 +00002642- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2643 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2644 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2645 single character on UCS-2 builds.

Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002681 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002682 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002683 replacement for old handle_accept() and avoids the user to call accept()
2684 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00002708 retry the select() loop instead of bailing out. This is because select() can
2709 incorrectly report a socket as ready for reading (for example, if it received
2710 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002790- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002791 it possible for the user to create self-referencing ordered dictionaries which
2792 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002793 approach of using weakref proxies so that reference cycles never get created
2794 in the first place.
2795
Victor Stinnercb043522010-09-10 23:49:04 +00002796- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002800- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2801 environment variable to set the filesystem encoding at Python startup.
2802 sys.setfilesystemencoding() creates inconsistencies because it is unable to

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002819- Issue #6394: os.getppid() is now supported on Windows. Note that it will

2821 id may even have been reused by another unrelated process.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002832- Updates to the random module:
2833
Georg Brandl27a28582010-10-10 09:49:21 +00002834 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002837 * Update the seed() method to use all of the bits in a string instead of just
2838 the hash value. This makes better use of the seed value and assures the
2839 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002840
Georg Brandl27a28582010-10-10 09:49:21 +00002841 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2842 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2843 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002844
2845 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002864- hashlib has two new constant attributes: algorithms_guaranteed and

2866 guaranteed to exist in all Python implementations and the names of hash
2867 algorithms available in the current process.

2996 return characters from the full Unicode range, even on narrow unicode builds
2997 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2998 in Python is that unicodedata.numeric() now returns the correct value for
2999 large code points, and repr() may consider more characters as printable.

Mark Dickinson388122d2010-08-04 20:56:28 +00003035
Georg Brandl649971e2010-09-05 17:06:50 +00003036- Issue #9416: Fix some issues with complex formatting where the output with no
3037 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003038
3039 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Georg Brandl62069d32010-07-31 08:56:11 +00003399- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3400 dealing with unary minus applied to a constant. The removed code was mutating
3401 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00003403- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003404 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003405 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003406 handlers. Patch written by Mark Hammond.

3410
Victor Stinner06e49dd2010-06-13 18:21:50 +00003411- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003412 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003413 string formats.
3414
Georg Brandl62069d32010-07-31 08:56:11 +00003415- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003416 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3417 location of the raised exception.
3418
Victor Stinner313a1202010-06-11 23:56:51 +00003419- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3420 filenames and enable os.fsencode().

3423
Georg Brandl62069d32010-07-31 08:56:11 +00003424- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3425 interpreter with characters outside the Basic Multilingual Plane (higher than
3426 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003427
Georg Brandl62069d32010-07-31 08:56:11 +00003428- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3429 TypeError instead of giving a DeprecationWarning when a float is parsed using
3430 the 'L' code (for long long). (All other integer codes already raise
3431 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003432
Victor Stinner600d3be2010-06-10 12:00:55 +00003433- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3434 enable shortcuts for upper case encoding name. Add also a shortcut for
3435 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3436
Georg Brandl62069d32010-07-31 08:56:11 +00003437- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3438 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003439
3440- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003441 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003442 like bytearray.
3443
Georg Brandl62069d32010-07-31 08:56:11 +00003444- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003445 used anymore and it was never documented.
3446
Georg Brandl62069d32010-07-31 08:56:11 +00003447- In str.format(), raise a ValueError when indexes to arguments are too large.

Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003451
Georg Brandl62069d32010-07-31 08:56:11 +00003452- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3453 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3454 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3455 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003456
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003457- Issue #8748: Fix two issues with comparisons between complex and integer
3458 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003459 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3460 (2) The comparison raised an OverflowError for large integers, leading to
3461 unpredictable exceptions when combining integers and complex objects in sets
3462 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003463

3465 Fix a crash if an empty directory called "encodings" exists in sys.path.
3466
Victor Stinner9ca9c252010-05-19 16:53:30 +00003467- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003468 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003469 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003470
Georg Brandl62069d32010-07-31 08:56:11 +00003471- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3472 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003473
Victor Stinnerae6265f2010-05-15 16:27:27 +00003474- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3475 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003476 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003477 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003478
Victor Stinner59e62db2010-05-15 13:14:32 +00003479- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003480 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003481
Victor Stinnerb744ba12010-05-15 12:27:16 +00003482- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003483 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003484 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3485
Victor Stinner0964ee12010-04-30 16:48:45 +00003486- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003487 PyUnicode_FromString() to support surrogates in the filename and use the right
3488 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003489
Georg Brandl8569e582010-05-19 20:57:08 +00003490- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.

Victor Stinnerdcb24032010-04-22 12:08:36 +00003506
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003507- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003508 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

Mark Dickinsonf673f0c2010-03-13 09:48:39 +00003541- Issue #7845: Rich comparison methods on the complex type now return
3542 NotImplemented rather than raising a TypeError when comparing with an
3543 incompatible type; this allows user-defined classes to implement their own
3544 comparisons with complex.

Georg Brandl62069d32010-07-31 08:56:11 +00003592 where the right hand operand is a set of constants, by turning the set into a
3593 frozenset and pre-building it as a constant. The comparison operation is made
3594 against the constant instead of building a new set each time it is executed (a
3595 similar optimization already existed which turned a list of constants into a
3596 pre-built tuple). Patch and additional tests by Dave Malcolm.

3902 the performance hit anytime the cache is exceeded.

4303 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004304
4305 >>> Decimal(1.1)
4306 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004311- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4312 InvalidOperation instead of returning False. (Comparisons involving a quiet
4313 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4314 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004316- Issue #2531: Comparison operations between floats and Decimal instances now
4317 return a result based on the numeric values of the operands; previously they
4318 returned an arbitrary result based on the relative ordering of id(float) and
4319 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4320 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004324- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004325 argument `-` which tells it to read files to compile from stdin. Each line is
4326 read on demand and the named file is compiled immediately. (Original patch by
4327 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004329- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004333- Comparisons using one of <, <=, >, >= between a complex instance and a
4334 Fractions instance now raise TypeError instead of returning True/False. This
4335 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4336 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004379- The internals of the subprocess module on POSIX systems have been replaced by
4380 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4381 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004383- subprocess.Popen now has restore_signals and start_new_session features. The
4384 default of restore_signals=True is a new behavior compared to earlier Python
4385 versions. This means that signals such as SIGPIPE are not ignored by default
4386 in subprocesses launched by Python (Issue #1652).

4473 position when calling `truncate()`. It would previously change the file
4474 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004475 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4479 archive. The new implementation is significantly faster and can be wrapped in
4480 a :class:`io.BufferedReader` object for more speedups. It also solves an
4481 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00004817- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004818 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4819 PyPycLoader inherit from this class and provide implementations in relation to
4820 other methods required by the ABCs.

Brett Cannon64ef00f2009-07-20 03:19:18 +00004822- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4823 the documentation said it did even though the code in PyLoader relied on the
4824 abstract method required by ResourceLoader.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004879- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004880 compared to other unix systems. In particular, os.getgroups() does not reflect
4881 any changes made using os.setgroups() but basicly always returns the same
4882 information as the id command. os.getgroups() can now return more than 16
4883 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00004908- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4909 Prior to this change, timezone adjustment in utctimetuple() could produce
4910 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

4914 directive. When the ``%z`` directive is present in the format string, an
4915 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4916 ``datetime.timezone`` instance constructed from the parsed offset. If both
4917 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4918 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004920- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004921 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4922 ``datetime.timezone``, return fixed name and UTC offset from their
4923 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4924 returns ``None``. A class attribute, ``utc`` contains an instance
4925 representing the UTC timezone. Original patch by Rafe Kaplan.

4942 with an improved 'binary-split' algorithm that uses fewer multiplications and
4943 allows many of the multiplications to be performed using plain C integer
4944 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

4951 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004952 the result is now always correctly rounded, and is equivalent to ``td /

Mark Hammond5a607a32009-05-06 08:04:54 +00005538- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5539 in all operations, including splitdrive, split, etc. splitunc() now issues
5540 a PendingDeprecation warning.
5541
Eric Smith63376222009-05-05 14:04:18 +00005542- Issue #5920: For float.__format__, change the behavior with the
5543 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5544 to be like 'g' but with at least one decimal point and with a
5545 default precision of 12. Previously, the behavior the same but with
5546 a default precision of 6. This more closely matches str(), and
5547 reduces surprises when adding alignment flags to the empty
5548 presentation type. This also affects the new complex.__format__ in
5549 the same way.
5550
Martin v. Löwis011e8422009-05-05 04:43:17 +00005551- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5552
R. David Murrayb18500d2009-05-04 22:59:07 +00005553- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5554 shadowed by classtype's, even if it was None. property now
5555 inserts the __doc__ into the subclass instance __dict__.
5556
Antoine Pitrou244651a2009-05-04 18:56:13 +00005557- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00005562- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5563 received a new method, detach(). detach() disconnects the underlying stream
5564 from the buffer or text IO and returns it.
5565
Mark Dickinson33841c32009-05-01 15:37:04 +00005566- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5567 floats with absolute value over 1e50. Also remove length
5568 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5569 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005570
Eric Smith741191f2009-05-06 13:08:15 +00005571- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005572 format(complex(1, 2./3), '.5') now produces a sensible result.
5573
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005574- Issue #5864: Fix empty format code formatting for floats so that it
5575 never gives more than the requested number of significant digits.
5576
Eric Smith6dc46f52009-04-27 20:39:49 +00005577- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +00005587- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5588 z involves nans, infs or negative zeros.
5589
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005590- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005591
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005592- Issue #1869 (and many duplicates): make round(x, n) correctly
5593 rounded for a float x, by using the decimal <-> binary conversions
5594 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5595 consistently agrees with format(x, '.2f').
5596
Benjamin Petersonae937c02009-04-18 20:54:08 +00005597- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5598 some builtin types.
5599
Eric Smith0923d1d2009-04-16 20:16:10 +00005600- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5601
Eric Smith35e84722009-04-16 20:21:28 +00005602- Issue #5515: str.format() type 'n' combined with commas and leading
5603 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005604
5605- Implement PEP 378, Format Specifier for Thousands Separator, for
5606 floats.
5607
Mark Dickinson3370cce2009-04-17 22:40:53 +00005608- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005609 1e11, not 1e12. This avoids printing 13 significant digits in
5610 situations where only 12 of them are correct. Example problem
5611 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5612 long time.)
5613
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005614- Issue #1580: On most platforms, use a 'short' float repr: for a
5615 finite float x, repr(x) now outputs a string based on the shortest
5616 sequence of decimal digits that rounds to x. Previous behaviour was
5617 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005618 Another minor difference is that the new repr switches to
5619 exponential notation at 1e16 instead of the previous 1e17; this
5620 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005621
5622 There's a new sys attribute sys.float_repr_style, which takes
5623 the value 'short' to indicate that we're using short float repr,
5624 and 'legacy' if the short float repr isn't available for one
5625 reason or another.
5626
5627 The float repr change involves incorporating David Gay's 'perfect
5628 rounding' code into the Python core (it's in Python/dtoa.c). As a
5629 secondary consequence, all string-to-float and float-to-string
5630 conversions (including all float formatting operations) will be
5631 correctly rounded on these platforms.
5632
Georg Brandl5f90d792010-08-01 22:31:05 +00005633 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005634 this change does not apply.
5635
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005636- Issue #5759: float() didn't call __float__ on str subclasses.
5637
Georg Brandlabc38772009-04-12 15:51:51 +00005638- The string.maketrans() function is deprecated; there is a new static method
5639 maketrans() on the bytes and bytearray classes. This removes confusion about
5640 the types string.maketrans() is supposed to work with, and mirrors the
5641 methods available on the str class.
5642
R. David Murraydc6da8a2009-04-09 22:16:43 +00005643- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

5648
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005649- Issue #3739: The unicode-internal encoder now reports the number of characters

5788
Benjamin Peterson7fe98532009-04-02 00:33:55 +00005789- Issue #5499: The 'c' code for argument parsing functions now only accepts a

5808
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005809- Issue #4688: Add a heuristic so that tuples and dicts containing only
5810 untrackable objects are not tracked by the garbage collector. This can
5811 reduce the size of collections and therefore the garbage collection overhead
5812 on long-running programs, depending on their particular use of datatypes.

5819 2**15 for the internal representation of integers, for performance
5820 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5821 --enable-big-digits option to configure, which overrides the
5822 default. Add sys.int_info structseq to provide information about
5823 the internal format.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005935- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5936 it now forces its argument to double before testing for infinity.
5937
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005938- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5939 returns a non-number type.
5940
Benjamin Peterson87618552009-02-08 15:00:52 +00005941- Issue #5182: Removed memoryview.__str__.
5942
Mark Dickinsonc008a172009-02-01 13:59:22 +00005943- Issue #1717: Removed builtin cmp() function, dropped tp_compare

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005947
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005948- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005949 were suppressing all exceptions. These include list() and bytearray().
5950
Mark Dickinson1124e712009-01-28 21:25:58 +00005951- Issue #4707: round(x, n) now returns an integer if x is an integer.
5952 Previously it returned a float.
5953
Antoine Pitroub52ec782009-01-25 16:34:23 +00005954- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5955 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5956 evaluation loop is compiled with a new dispatch mechanism which gives
5957 speedups of up to 20%, depending on the system, on various benchmarks.
5958
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005959- Issue #4874: Most builtin decoders now reject unicode input.

5967 optional module state data.
5968
Mark Dickinson8055afd2009-01-17 10:04:45 +00005969- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005970 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005971
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005972- Issue #4935: The overflow checking code in the expandtabs() method common
5973 to str, bytes and bytearray could be optimized away by the compiler, letting
5974 the interpreter segfault instead of raising an error.
5975
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005976- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5977 __next__ method.
5978
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005979- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5980 function no longer attempt to call the __long__ slot to convert an object
5981 to an integer. Only the __int__ and __trunc__ slots are examined.
5982
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005983- Issue #4893: Use NT threading on CE.
5984

5986
Antoine Pitrouab868312009-01-10 15:40:25 +00005987- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5988 common cases are optimized thanks to a dedicated fast path and a moderate
5989 amount of loop unrolling.
5990
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005991- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5992 collecting the oldest generation) so that allocating lots of objects without
5993 destroying them does not show quadratic performance. Based on a proposal by
5994 Martin von Löwis at
5995 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5996
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005997- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005998 having been closed (for instance, a read() call could return some
5999 previously buffered data). Patch by Dmitry Vasiliev.
6000
Antoine Pitrou05608432009-01-09 18:53:14 +00006001- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6002 flag to work properly. Furthermore, when specifying -u, the text stdout
6003 and stderr streams have line-by-line buffering enabled (the default being
6004 to buffer arbitrary chunks of data).
6005
Raymond Hettinger35631532009-01-09 03:58:09 +00006006- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6007 instead of ints (reducing its size from 4 to 8 times thereby reducing
6008 Python's overall memory).
6009
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006010- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6011 an existing .py counterpart, override the co_filename attributes of all
6012 code objects if the original filename is obsolete (which can happen if the
6013 file has been renamed, moved, or if it is accessed through different paths).
6014 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6015
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006016- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6017 one byte. Also fixes the meaning of len() so that it returns the number of
6018 items, rather than the size in bytes.
6019
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006020- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6021
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006022- Issue #4747: When the terminal does not use utf-8, executing a script with
6023 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6024
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006025- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6026 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006027
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006028- Issue #3680: Reference cycles created through a dict, set or deque iterator
6029 did not get collected.
6030
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006031- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6032 where the tp_hash and tp_dict slots are both NULL.
6033
Georg Brandlccc47b62008-12-28 11:44:14 +00006034- Issue #4759: None is now allowed as the first argument of
6035 bytearray.translate(). It was always allowed for bytes.translate().
6036
Skip Montanaro80072cb2008-12-23 03:51:14 +00006037- Added test case to ensure attempts to read from a file opened for writing
6038 fail.
6039
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006040- Issue #3106: Speedup some comparisons (str/str and int/int).

6043 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6044
Antoine Pitrou621601a2008-12-17 23:18:19 +00006045- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6046 print elapsed times, not only when some objects are uncollectable /
6047 unreachable. Original patch by Neil Schemenauer.
6048
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006049- Issue #3439: Add a bit_length method to int.
6050
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006051- Issue #2173: When getting device encoding, check that return value of
6052 nl_langinfo is not the empty string. This was causing silent build
6053 failures on OS X.
6054
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006055- Issue #4597: Fixed several opcodes that weren't always propagating
6056 exceptions.
6057
6058- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006059 context manager returns a value that cannot be converted to a bool.
6060
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006061- Issue #4445: Replace "sizeof(PyBytesObject)" with
6062 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6063 bytes instances. On a typical machine this saves 3 bytes of memory
6064 (on average) per allocation of a bytes instance.
6065
Christian Heimesa872de52008-12-05 08:26:55 +00006066- Issue #4533: File read operation was dreadfully slow due to a slowly
6067 growing read buffer. Fixed by using the same growth rate algorithm as
6068 Python 2.x.
6069
Antoine Pitrou5504e892008-12-06 21:27:53 +00006070- Issue #4509: Various issues surrounding resize of bytearray objects to
6071 which there are buffer exports (e.g. memoryview instances).
6072
Georg Brandlf9734072008-12-07 15:30:06 +00006073- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6074 method on file objects with closefd=False. The file descriptor is still
6075 kept open but the file object behaves like a closed file. The ``FileIO``
6076 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006077
Antoine Pitroubc420402008-12-07 20:14:49 +00006078- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6079 larger than 1.

6084
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006085- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6086 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6087 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6088 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00006690- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6691 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00006693- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6694 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6695 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6696 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00006698- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006699 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006700 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00006702- Issue #5083: New 'gui' resource for regrtest.
