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

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.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001572- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001573 continuation line in the formatted value has no leading white space and looks
1574 like a header. Since Generator uses Header to format all headers, this check
1575 is made for all headers in any serialized message at serialization time. This
1576 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001577

Georg Brandl255abdd2011-01-16 14:17:26 +00001586 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001587
Éric Araujof0ab5d62011-05-29 03:43:59 +02001588- email.header.Header was incorrectly encoding folding whitespace when

1590 folding whitespace. It now uses the continuation_ws, as it does for

1596 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1597 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1598 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

2205
Antoine Pitroucf9f9802010-11-10 13:55:25 +00002206- Issue #10372: Import the warnings module only after the IO library is
2207 initialized, so as to avoid bootstrap issues with the '-W' option.
2208

Eric Smith27bbca62010-11-04 17:06:58 +00002214
Benjamin Petersonbbb04122010-10-30 23:16:28 +00002215- If FileIO.__init__ fails, close the file descriptor.
2216
Raymond Hettingerdd421542010-10-30 08:10:29 +00002217- Issue #10221: dict.pop(k) now has a key error message that includes the
2218 missing key (same message d[k] returns for missing keys).
2219
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002220- Issue #5437: A preallocated MemoryError instance should not keep traceback

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002229- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2230 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002231 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002232 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002233 encoding and to encode command line arguments on this OS.
2234

2236 filenames encoded to the filesystem encoding with the surrogateescape error
Victor Stinner4c7c8c32010-10-16 13:14:10 +00002237 handler (to support undecodable bytes), instead of UTF-8 in strict mode.
2238
Benjamin Peterson230b2062010-10-16 03:45:45 +00002239- Issue #9997: Don't let the name "top" have special significance in scope
2240 resolution.
2241

R. David Murraye16cda92010-10-15 23:12:57 +00002244
Victor Stinnerf3170cc2010-10-15 12:04:23 +00002245- Use locale encoding instead of UTF-8 to encode and decode filenames if

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002285 unexpectedly if the return value of a task could not be pickled. Only the
2286 ``repr`` of such errors are now sent back, wrapped in an
Ask Soleme912f5a2010-11-09 21:14:53 +00002287 ``MaybeEncodingError`` exception.
2288
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002289- Issue #9244: The ``apply_async()`` and ``map_async()`` methods of
2290 ``multiprocessing.Pool`` now accepts a ``error_callback`` argument. This can

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002346 incorrectly validated some non-compliant applications as WSGI compliant; if

2626 with a non-empty format string. This is an effort to future-proof user
2627 code. If a derived class does not currently implement __format__ but later
2628 adds its own __format__, it would most likely break user code that had
2629 supplied a format string. This will be changed to a DeprecationWaring in
2630 Python 3.3 and it will be an error in Python 3.4.

2634 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002643- Issue #4617: Previously it was illegal to delete a name from the local
2644 namespace if it occurs as a free variable in a nested block. This limitation
2645 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2646
Georg Brandl27a28582010-10-10 09:49:21 +00002647- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2648 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2649 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2650 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002685- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002686 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002687 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002688 replacement for old handle_accept() and avoids the user to call accept()
2689 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00002713 retry the select() loop instead of bailing out. This is because select() can
2714 incorrectly report a socket as ready for reading (for example, if it received
2715 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002795- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002796 it possible for the user to create self-referencing ordered dictionaries which
2797 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002798 approach of using weakref proxies so that reference cycles never get created
2799 in the first place.
2800
Victor Stinnercb043522010-09-10 23:49:04 +00002801- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2802 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002803 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002804
Georg Brandl27a28582010-10-10 09:49:21 +00002805- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2806 environment variable to set the filesystem encoding at Python startup.
2807 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2808 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002809
Georg Brandl27a28582010-10-10 09:49:21 +00002810- Issue #9410: Various optimizations to the pickle module, leading to speedups

Georg Brandl27a28582010-10-10 09:49:21 +00002814- The pprint module now supports printing OrderedDicts in their given order

Vinay Sajip121a1c42010-09-08 10:46:15 +00002817- Logging: Added QueueHandler class to facilitate logging usage with
2818 multiprocessing.
2819
Georg Brandl27a28582010-10-10 09:49:21 +00002820- Issue #9707: Rewritten reference implementation of threading.local which is
2821 friendlier towards reference cycles. This change is not normally visible
2822 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002823
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002824- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2825 still return the id of the parent process after it has exited. This process
2826 id may even have been reused by another unrelated process.
2827
Georg Brandl27a28582010-10-10 09:49:21 +00002828- Issue #9792: In case of connection failure, socket.create_connection() would
2829 swallow the exception and raise a new one, making it impossible to fetch the
2830 original errno, or to filter timeout errors. Now the original error is
2831 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002833- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2834 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2835 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002837- Updates to the random module:
2838
Georg Brandl27a28582010-10-10 09:49:21 +00002839 * Document which parts of the module are guaranteed to stay the same across
2840 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002841
Georg Brandl27a28582010-10-10 09:49:21 +00002842 * Update the seed() method to use all of the bits in a string instead of just
2843 the hash value. This makes better use of the seed value and assures the
2844 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002845
Georg Brandl27a28582010-10-10 09:49:21 +00002846 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2847 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2848 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002849
2850 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002869- hashlib has two new constant attributes: algorithms_guaranteed and

2871 guaranteed to exist in all Python implementations and the names of hash
2872 algorithms available in the current process.

3001 return characters from the full Unicode range, even on narrow unicode builds
3002 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3003 in Python is that unicodedata.numeric() now returns the correct value for
3004 large code points, and repr() may consider more characters as printable.

Victor Stinner47fcb5b2010-08-13 23:59:58 +00003022- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003023 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3024 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00003030- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3031 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00003032

3039 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003040
Georg Brandl649971e2010-09-05 17:06:50 +00003041- Issue #9416: Fix some issues with complex formatting where the output with no
3042 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003043
3044 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3045 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Georg Brandl62069d32010-07-31 08:56:11 +00003404- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3405 dealing with unary minus applied to a constant. The removed code was mutating
3406 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00003408- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003409 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003410 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003411 handlers. Patch written by Mark Hammond.

3415
Victor Stinner06e49dd2010-06-13 18:21:50 +00003416- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003417 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003418 string formats.
3419
Georg Brandl62069d32010-07-31 08:56:11 +00003420- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003421 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3422 location of the raised exception.

3428
Georg Brandl62069d32010-07-31 08:56:11 +00003429- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3430 interpreter with characters outside the Basic Multilingual Plane (higher than
3431 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003432
Georg Brandl62069d32010-07-31 08:56:11 +00003433- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3434 TypeError instead of giving a DeprecationWarning when a float is parsed using
3435 the 'L' code (for long long). (All other integer codes already raise
3436 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003437
Victor Stinner600d3be2010-06-10 12:00:55 +00003438- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3439 enable shortcuts for upper case encoding name. Add also a shortcut for
3440 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3441
Georg Brandl62069d32010-07-31 08:56:11 +00003442- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3443 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003444
3445- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003446 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003447 like bytearray.
3448
Georg Brandl62069d32010-07-31 08:56:11 +00003449- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003450 used anymore and it was never documented.
3451
Georg Brandl62069d32010-07-31 08:56:11 +00003452- In str.format(), raise a ValueError when indexes to arguments are too large.

Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003456
Georg Brandl62069d32010-07-31 08:56:11 +00003457- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3458 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3459 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3460 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003461
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003462- Issue #8748: Fix two issues with comparisons between complex and integer
3463 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003464 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3465 (2) The comparison raised an OverflowError for large integers, leading to
3466 unpredictable exceptions when combining integers and complex objects in sets
3467 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003468

3471
Victor Stinner9ca9c252010-05-19 16:53:30 +00003472- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003473 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003474 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003475
Georg Brandl62069d32010-07-31 08:56:11 +00003476- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3477 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003478
Victor Stinnerae6265f2010-05-15 16:27:27 +00003479- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3480 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003481 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003482 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003483
Victor Stinner59e62db2010-05-15 13:14:32 +00003484- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003485 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003486
Victor Stinnerb744ba12010-05-15 12:27:16 +00003487- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003488 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003489 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3490
Victor Stinner0964ee12010-04-30 16:48:45 +00003491- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003492 PyUnicode_FromString() to support surrogates in the filename and use the right
3493 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003494
Georg Brandl8569e582010-05-19 20:57:08 +00003495- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.

Victor Stinnerdcb24032010-04-22 12:08:36 +00003511
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003512- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003513 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

Mark Dickinsonf673f0c2010-03-13 09:48:39 +00003546- Issue #7845: Rich comparison methods on the complex type now return
3547 NotImplemented rather than raising a TypeError when comparing with an
3548 incompatible type; this allows user-defined classes to implement their own
3549 comparisons with complex.

Georg Brandl62069d32010-07-31 08:56:11 +00003597 where the right hand operand is a set of constants, by turning the set into a
3598 frozenset and pre-building it as a constant. The comparison operation is made
3599 against the constant instead of building a new set each time it is executed (a
3600 similar optimization already existed which turned a list of constants into a
3601 pre-built tuple). Patch and additional tests by Dave Malcolm.

3907 the performance hit anytime the cache is exceeded.

4308 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004309
4310 >>> Decimal(1.1)
4311 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004316- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4317 InvalidOperation instead of returning False. (Comparisons involving a quiet
4318 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4319 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004321- Issue #2531: Comparison operations between floats and Decimal instances now
4322 return a result based on the numeric values of the operands; previously they
4323 returned an arbitrary result based on the relative ordering of id(float) and
4324 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4325 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004329- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004330 argument `-` which tells it to read files to compile from stdin. Each line is
4331 read on demand and the named file is compiled immediately. (Original patch by
4332 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004334- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004338- Comparisons using one of <, <=, >, >= between a complex instance and a
4339 Fractions instance now raise TypeError instead of returning True/False. This
4340 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4341 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004384- The internals of the subprocess module on POSIX systems have been replaced by
4385 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4386 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004388- subprocess.Popen now has restore_signals and start_new_session features. The
4389 default of restore_signals=True is a new behavior compared to earlier Python
4390 versions. This means that signals such as SIGPIPE are not ignored by default
4391 in subprocesses launched by Python (Issue #1652).

4478 position when calling `truncate()`. It would previously change the file
4479 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004480 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00004482- Issue #7610: Reworked implementation of the internal

4484 archive. The new implementation is significantly faster and can be wrapped in
4485 a :class:`io.BufferedReader` object for more speedups. It also solves an
4486 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00004822- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004823 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4824 PyPycLoader inherit from this class and provide implementations in relation to
4825 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004826
Brett Cannon64ef00f2009-07-20 03:19:18 +00004827- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4828 the documentation said it did even though the code in PyLoader relied on the
4829 abstract method required by ResourceLoader.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004884- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004885 compared to other unix systems. In particular, os.getgroups() does not reflect
4886 any changes made using os.setgroups() but basicly always returns the same
4887 information as the id command. os.getgroups() can now return more than 16
4888 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00004913- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4914 Prior to this change, timezone adjustment in utctimetuple() could produce
4915 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4916 cases.

4919 directive. When the ``%z`` directive is present in the format string, an
4920 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4921 ``datetime.timezone`` instance constructed from the parsed offset. If both
4922 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4923 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004925- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004926 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4927 ``datetime.timezone``, return fixed name and UTC offset from their
4928 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4929 returns ``None``. A class attribute, ``utc`` contains an instance
4930 representing the UTC timezone. Original patch by Rafe Kaplan.

4947 with an improved 'binary-split' algorithm that uses fewer multiplications and
4948 allows many of the multiplications to be performed using plain C integer
4949 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

4956 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004957 the result is now always correctly rounded, and is equivalent to ``td /

4967 integer format code, struct.pack first attempts to convert the non-integer

Mark Hammond5a607a32009-05-06 08:04:54 +00005543- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5544 in all operations, including splitdrive, split, etc. splitunc() now issues
5545 a PendingDeprecation warning.
5546
Eric Smith63376222009-05-05 14:04:18 +00005547- Issue #5920: For float.__format__, change the behavior with the
5548 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5549 to be like 'g' but with at least one decimal point and with a
5550 default precision of 12. Previously, the behavior the same but with
5551 a default precision of 6. This more closely matches str(), and
5552 reduces surprises when adding alignment flags to the empty
5553 presentation type. This also affects the new complex.__format__ in
5554 the same way.
5555
Martin v. Löwis011e8422009-05-05 04:43:17 +00005556- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5557
R. David Murrayb18500d2009-05-04 22:59:07 +00005558- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5559 shadowed by classtype's, even if it was None. property now
5560 inserts the __doc__ into the subclass instance __dict__.
5561
Antoine Pitrou244651a2009-05-04 18:56:13 +00005562- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00005567- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5568 received a new method, detach(). detach() disconnects the underlying stream
5569 from the buffer or text IO and returns it.
5570
Mark Dickinson33841c32009-05-01 15:37:04 +00005571- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5572 floats with absolute value over 1e50. Also remove length
5573 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5574 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005575
Eric Smith741191f2009-05-06 13:08:15 +00005576- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005577 format(complex(1, 2./3), '.5') now produces a sensible result.
5578
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005579- Issue #5864: Fix empty format code formatting for floats so that it
5580 never gives more than the requested number of significant digits.
5581
Eric Smith6dc46f52009-04-27 20:39:49 +00005582- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Benjamin Peterson193152c2009-04-25 01:08:45 +00005590- Issue #5283: Setting __class__ in __del__ caused a segfault.
5591
Mark Dickinsonad476da2009-04-23 19:14:16 +00005592- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5593 z involves nans, infs or negative zeros.
5594
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005595- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005596
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005597- Issue #1869 (and many duplicates): make round(x, n) correctly
5598 rounded for a float x, by using the decimal <-> binary conversions
5599 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5600 consistently agrees with format(x, '.2f').
5601
Benjamin Petersonae937c02009-04-18 20:54:08 +00005602- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5603 some builtin types.
5604
Eric Smith0923d1d2009-04-16 20:16:10 +00005605- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5606
Eric Smith35e84722009-04-16 20:21:28 +00005607- Issue #5515: str.format() type 'n' combined with commas and leading
5608 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005609
5610- Implement PEP 378, Format Specifier for Thousands Separator, for
5611 floats.
5612
Mark Dickinson3370cce2009-04-17 22:40:53 +00005613- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005614 1e11, not 1e12. This avoids printing 13 significant digits in
5615 situations where only 12 of them are correct. Example problem
5616 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5617 long time.)
5618
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005619- Issue #1580: On most platforms, use a 'short' float repr: for a
5620 finite float x, repr(x) now outputs a string based on the shortest
5621 sequence of decimal digits that rounds to x. Previous behaviour was
5622 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005623 Another minor difference is that the new repr switches to
5624 exponential notation at 1e16 instead of the previous 1e17; this
5625 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005626
5627 There's a new sys attribute sys.float_repr_style, which takes
5628 the value 'short' to indicate that we're using short float repr,
5629 and 'legacy' if the short float repr isn't available for one
5630 reason or another.
5631
5632 The float repr change involves incorporating David Gay's 'perfect
5633 rounding' code into the Python core (it's in Python/dtoa.c). As a
5634 secondary consequence, all string-to-float and float-to-string
5635 conversions (including all float formatting operations) will be
5636 correctly rounded on these platforms.
5637
Georg Brandl5f90d792010-08-01 22:31:05 +00005638 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005639 this change does not apply.
5640
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005641- Issue #5759: float() didn't call __float__ on str subclasses.
5642
Georg Brandlabc38772009-04-12 15:51:51 +00005643- The string.maketrans() function is deprecated; there is a new static method
5644 maketrans() on the bytes and bytearray classes. This removes confusion about
5645 the types string.maketrans() is supposed to work with, and mirrors the
5646 methods available on the str class.
5647
R. David Murraydc6da8a2009-04-09 22:16:43 +00005648- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Walter Dörwald8dc33d52009-05-06 14:41:26 +00005654- Issue #3739: The unicode-internal encoder now reports the number of characters

Antoine Pitrou3a652b12009-03-23 18:52:06 +00005814- Issue #4688: Add a heuristic so that tuples and dicts containing only
5815 untrackable objects are not tracked by the garbage collector. This can
5816 reduce the size of collections and therefore the garbage collection overhead
5817 on long-running programs, depending on their particular use of datatypes.

5824 2**15 for the internal representation of integers, for performance
5825 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5826 --enable-big-digits option to configure, which overrides the
5827 default. Add sys.int_info structseq to provide information about
5828 the internal format.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005940- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5941 it now forces its argument to double before testing for infinity.
5942
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005943- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5944 returns a non-number type.
5945
Benjamin Peterson87618552009-02-08 15:00:52 +00005946- Issue #5182: Removed memoryview.__str__.
5947
Mark Dickinsonc008a172009-02-01 13:59:22 +00005948- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5949 slot, the C API functions PyObject_Compare and PyUnicode_Compare and

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005952
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005953- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005954 were suppressing all exceptions. These include list() and bytearray().
5955
Mark Dickinson1124e712009-01-28 21:25:58 +00005956- Issue #4707: round(x, n) now returns an integer if x is an integer.
5957 Previously it returned a float.
5958
Antoine Pitroub52ec782009-01-25 16:34:23 +00005959- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5960 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5961 evaluation loop is compiled with a new dispatch mechanism which gives
5962 speedups of up to 20%, depending on the system, on various benchmarks.
5963
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005964- Issue #4874: Most builtin decoders now reject unicode input.

5972 optional module state data.
5973
Mark Dickinson8055afd2009-01-17 10:04:45 +00005974- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005975 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005976
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005977- Issue #4935: The overflow checking code in the expandtabs() method common
5978 to str, bytes and bytearray could be optimized away by the compiler, letting
5979 the interpreter segfault instead of raising an error.
5980
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005981- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5982 __next__ method.
5983
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005984- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5985 function no longer attempt to call the __long__ slot to convert an object
5986 to an integer. Only the __int__ and __trunc__ slots are examined.
5987
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005988- Issue #4893: Use NT threading on CE.
5989

5991
Antoine Pitrouab868312009-01-10 15:40:25 +00005992- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5993 common cases are optimized thanks to a dedicated fast path and a moderate
5994 amount of loop unrolling.
5995
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005996- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5997 collecting the oldest generation) so that allocating lots of objects without
5998 destroying them does not show quadratic performance. Based on a proposal by
5999 Martin von Löwis at
6000 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6001
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006002- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006003 having been closed (for instance, a read() call could return some
6004 previously buffered data). Patch by Dmitry Vasiliev.
6005
Antoine Pitrou05608432009-01-09 18:53:14 +00006006- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6007 flag to work properly. Furthermore, when specifying -u, the text stdout
6008 and stderr streams have line-by-line buffering enabled (the default being
6009 to buffer arbitrary chunks of data).
6010
Raymond Hettinger35631532009-01-09 03:58:09 +00006011- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6012 instead of ints (reducing its size from 4 to 8 times thereby reducing
6013 Python's overall memory).
6014
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006015- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6016 an existing .py counterpart, override the co_filename attributes of all
6017 code objects if the original filename is obsolete (which can happen if the
6018 file has been renamed, moved, or if it is accessed through different paths).
6019 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6020
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006021- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6022 one byte. Also fixes the meaning of len() so that it returns the number of
6023 items, rather than the size in bytes.
6024
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006025- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6026
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006027- Issue #4747: When the terminal does not use utf-8, executing a script with
6028 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6029
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006030- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6031 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006032
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006033- Issue #3680: Reference cycles created through a dict, set or deque iterator
6034 did not get collected.
6035
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006036- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6037 where the tp_hash and tp_dict slots are both NULL.
6038
Georg Brandlccc47b62008-12-28 11:44:14 +00006039- Issue #4759: None is now allowed as the first argument of
6040 bytearray.translate(). It was always allowed for bytes.translate().
6041
Skip Montanaro80072cb2008-12-23 03:51:14 +00006042- Added test case to ensure attempts to read from a file opened for writing
6043 fail.
6044
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006045- Issue #3106: Speedup some comparisons (str/str and int/int).

6049
Antoine Pitrou621601a2008-12-17 23:18:19 +00006050- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6051 print elapsed times, not only when some objects are uncollectable /
6052 unreachable. Original patch by Neil Schemenauer.
6053
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006054- Issue #3439: Add a bit_length method to int.
6055
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006056- Issue #2173: When getting device encoding, check that return value of
6057 nl_langinfo is not the empty string. This was causing silent build
6058 failures on OS X.
6059
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006060- Issue #4597: Fixed several opcodes that weren't always propagating
6061 exceptions.
6062
6063- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006064 context manager returns a value that cannot be converted to a bool.
6065
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006066- Issue #4445: Replace "sizeof(PyBytesObject)" with
6067 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6068 bytes instances. On a typical machine this saves 3 bytes of memory
6069 (on average) per allocation of a bytes instance.
6070
Christian Heimesa872de52008-12-05 08:26:55 +00006071- Issue #4533: File read operation was dreadfully slow due to a slowly
6072 growing read buffer. Fixed by using the same growth rate algorithm as
6073 Python 2.x.
6074
Antoine Pitrou5504e892008-12-06 21:27:53 +00006075- Issue #4509: Various issues surrounding resize of bytearray objects to
6076 which there are buffer exports (e.g. memoryview instances).
6077
Georg Brandlf9734072008-12-07 15:30:06 +00006078- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6079 method on file objects with closefd=False. The file descriptor is still
6080 kept open but the file object behaves like a closed file. The ``FileIO``
6081 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00006083- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6084 larger than 1.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00006090- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6091 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6092 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6093 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00006695- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6696 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00006698- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6699 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6700 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6701 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00006703- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006704 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006705 from test support, which does the conversion.
6706
Guilherme Polo9de29af2009-01-28 20:40:48 +00006707- Issue #5083: New 'gui' resource for regrtest.
