11-----------------
12
Victor Stinner75d8c5c2010-10-23 17:02:31 +000013- Issue #6011: sysconfig and distutils.sysconfig use the surrogateescape error
14 handler to parse the Makefile file. Avoid a UnicodeDecodeError if the source
15 code directory name contains a non-ASCII character and the locale encoding is
16 ASCII.
17
Antoine Pitrou9583cac2010-10-21 13:42:28 +000018- Issue #10089: Add support for arbitrary -X options on the command-line.

20
Victor Stinnerf933e1a2010-10-20 22:58:25 +000021- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead
22 of the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
23 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
24 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
25 encoding and to encode command line arguments on this OS.
26
Victor Stinner4c7c8c32010-10-16 13:14:10 +000027- Issue #9713, #10114: Parser functions (eg. PyParser_ASTFromFile) expects
28 filenames encoded to the filesystem encoding with surrogateescape error
29 handler (to support undecodable bytes), instead of UTF-8 in strict mode.
30
Benjamin Peterson230b2062010-10-16 03:45:45 +000031- Issue #9997: Don't let the name "top" have special significance in scope
32 resolution.
33
R. David Murraye16cda92010-10-15 23:12:57 +000034- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding
35 its value as the default 512 when compiling on AIX.
36
Victor Stinnerf3170cc2010-10-15 12:04:23 +000037- Use locale encoding instead of UTF-8 to encode and decode filenames if
38 Py_FileSystemDefaultEncoding is not set.
39
Victor Stinner22a351a2010-10-14 12:04:34 +000040- Issue #10095: fp_setreadl() doesn't reopen the file, reuse instead the file
41 descriptor.
42
Georg Brandl66c221e2010-10-14 07:04:07 +000043- Issue #9418: Moved private string methods ``_formatter_parser`` and
44 ``_formatter_field_name_split`` into a new ``_string`` module.
45
Victor Stinner8f6b6b02010-10-13 22:02:27 +000046- Issue #9992: Remove PYTHONFSENCODING environment variable.

Antoine Pitroud5323212010-10-22 18:19:07 +000051- Issue #5639: Add a *server_hostname* argument to ``SSLContext.wrap_socket``
52 in order to support the TLS SNI extension. ``HTTPSConnection`` and
53 ``urlopen()`` also use this argument, so that HTTPS virtual hosts are now
54 supported.
55
Georg Brandl83938432010-10-22 06:28:01 +000056- Issue #10166: Avoid recursion in pstats Stats.add() for many stats items.

71
Hirokazu Yamamotob08820a2010-10-18 12:13:18 +000072- Issue #5117: Case normalization was needed on ntpath.relpath(). And
73 fixed root directory issue on posixpath.relpath(). (Ported working fixes
74 from ntpath)
75
R. David Murraya90032a2010-10-17 22:46:45 +000076- Issue #1343: xml.sax.saxutils.XMLGenerator now has an option

78
Barry Warsawf6219a52010-10-16 01:20:45 +000079- Issue #9807 (part 1): Expose the ABI flags in sys.abiflags. Add --abiflags
80 switch to python-config for command line access.
81
Georg Brandl3844f0d2010-10-15 18:00:35 +000082- Issue #6098: Don't claim DOM level 3 conformance in minidom.

Victor Stinner4c7c8c32010-10-16 13:14:10 +000088 characters by default. Deprecate ``cgi.escape()``.
Georg Brandl1f7fffb2010-10-15 15:57:45 +000089
Georg Brandld2413422010-10-15 16:42:14 +000090- Issue #9409: Fix the regex to match all kind of filenames, for interactive

Alexander Belopolsky1bcbaab2010-10-14 17:03:51 +000094 return the same instance as ``datetime.timezone.utc``.
95
Antoine Pitroub1c54962010-10-14 15:05:38 +000096- Issue #7523: Add SOCK_CLOEXEC and SOCK_NONBLOCK to the socket module,
97 where supported by the system. Patch by Nikita Vetoshkin.

181
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +0000182- Issue #10068: Global objects which have reference cycles with their module's
183 dict are now cleared again. This causes issue #7140 to appear again.
184
Victor Stinner257d38f2010-10-09 10:12:11 +0000185- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +0000186 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +0000187
Georg Brandl27a28582010-10-10 09:49:21 +0000188- ast.literal_eval() can now handle negative numbers. It is also a little more
189 liberal in what it accepts without compromising the safety of the evaluation.
190 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +0000191
Benjamin Peterson970d1882010-10-02 17:55:47 +0000192- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
193 result metaclasses can now be ABCs (see #9533).
194
Victor Stinneraef57e32010-10-02 11:50:49 +0000195- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
196
Victor Stinner5593d8a2010-10-02 11:11:27 +0000197- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +0000198 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
199 32 bits wchar_t (eg. Linux in narrow build).

Victor Stinner137c34c2010-09-29 10:25:54 +0000204- Issue #9979: Create function PyUnicode_AsWideCharString().
205
Brett Cannon5305a992010-09-27 21:08:38 +0000206- Issue #7397: Mention that importlib.import_module() is probably what someone
207 really wants to be using in __import__'s docstring.
208
Georg Brandl27a28582010-10-10 09:49:21 +0000209- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
210 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +0000211
Mark Dickinsonb09a3d62010-09-23 20:11:19 +0000212- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +0000213 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +0000214
Brian Curtine8e4b3b2010-09-23 20:04:14 +0000215- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
216
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +0000217- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
218 threads are still running. Instead, reinitialize the GIL on a second call to
219 Py_Initialize().
220
Georg Brandl27a28582010-10-10 09:49:21 +0000221- All SyntaxErrors now have a column offset and therefore a caret when the error
222 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +0000223
Brett Cannonbc2eff32010-09-19 21:39:02 +0000224- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
225 module that was imported, but instead gets the module from sys.modules.
226
Georg Brandl27a28582010-10-10 09:49:21 +0000227- Issue #9212: The range type_items now provides index() and count() methods, to
228 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +0000229
Georg Brandl27a28582010-10-10 09:49:21 +0000230- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
231 with a non-empty format string. This is an effort to future-proof user
232 code. If a derived class does not currently implement __format__ but later
233 adds its own __format__, it would most likely break user code that had
234 supplied a format string. This will be changed to a DeprecationWaring in
235 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +0000236
Antoine Pitrou1df15362010-09-13 14:16:46 +0000237- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
238 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
239 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
240
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +0000241- Issue #9210: Configure option --with-wctype-functions was removed. Using the
242 functions from the libc caused the methods .upper() and lower() to become
243 locale aware and created subtly wrong results.
244
Georg Brandl27a28582010-10-10 09:49:21 +0000245- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
246 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +0000247
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +0000248- Issue #4617: Previously it was illegal to delete a name from the local
249 namespace if it occurs as a free variable in a nested block. This limitation
250 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
251
Georg Brandl27a28582010-10-10 09:49:21 +0000252- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
253 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
254 Also, the "backslashreplace" error handler now joins surrogate pairs into a
255 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +0000256
Antoine Pitrou6e6cc832010-09-09 12:59:39 +0000257- Issue #9757: memoryview objects get a release() method to release the
258 underlying buffer (previously this was only done when deallocating the
259 memoryview), and gain support for the context management protocol.
260
Antoine Pitrou079ce542010-09-08 12:37:10 +0000261- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
262 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +0000269- Issue #4661: email can now parse bytes input and generate either converted
270 7bit output or bytes output. Email version bumped to 5.1.0.
271
Antoine Pitrou59fdd672010-10-08 10:37:08 +0000272- Issue #1589: Add ssl.match_hostname(), to help implement server identity
273 verification for higher-level protocols.
274
Antoine Pitrou7980eaa2010-10-06 21:21:18 +0000275- Issue #9759: GzipFile now raises ValueError when an operation is attempted

Éric Araujo6108bf52010-10-04 23:52:37 +0000278- Issue #9042: Fix interaction of custom translation classes and caching in
279 gettext.
280
Éric Araujoef777bd2010-10-05 00:04:20 +0000281- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method

Raymond Hettingerfa11db02010-09-12 04:12:42 +0000391- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +0000392 it possible for the user to create self-referencing ordered dictionaries which
393 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +0000394 approach of using weakref proxies so that reference cycles never get created
395 in the first place.

398 encode the value with filesystem encoding and surrogateescape (instead of

421 still return the id of the parent process after it has exited. This process
422 id may even have been reused by another unrelated process.
423
Georg Brandl27a28582010-10-10 09:49:21 +0000424- Issue #9792: In case of connection failure, socket.create_connection() would

Georg Brandl27a28582010-10-10 09:49:21 +0000438 * Update the seed() method to use all of the bits in a string instead of just
439 the hash value. This makes better use of the seed value and assures the
440 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +0000441
Georg Brandl27a28582010-10-10 09:49:21 +0000442 * Improved the random()-->integer algorithm used in choice(), shuffle(),
443 sample(), randrange(), and randint(). Formerly, it used int(n*random())
444 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +0000445
446 * Improved documentation of arguments to randrange(). Issue #9379.

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

597 return characters from the full Unicode range, even on narrow unicode builds
598 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

Victor Stinner47fcb5b2010-08-13 23:59:58 +0000618- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +0000619 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
620 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +0000626- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
627 use PyUnicode_FromFormatV() to format the warning message.

635 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +0000636
Georg Brandl649971e2010-09-05 17:06:50 +0000637- Issue #9416: Fix some issues with complex formatting where the output with no
638 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +0000639
640 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
641 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Georg Brandl62069d32010-07-31 08:56:11 +0000975 start byte and the continuation byte(s) are now considered invalid, instead of
976 the number of bytes specified by the start byte. E.g.:

978 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
979 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
980 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00001023- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
1024 TypeError instead of giving a DeprecationWarning when a float is parsed using
1025 the 'L' code (for long long). (All other integer codes already raise
1026 TypeError in this case.)

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001052- Issue #8748: Fix two issues with comparisons between complex and integer
1053 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00001054 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
1055 (2) The comparison raised an OverflowError for large integers, leading to
1056 unpredictable exceptions when combining integers and complex objects in sets

Victor Stinner0964ee12010-04-30 16:48:45 +00001081- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of

Georg Brandl62069d32010-07-31 08:56:11 +00001245- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
1246 range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
1247 long but the length of the range did not. Also fix several cases where
1248 reversed(range(a, b, c)) gave wrong results, and fix a refleak for
1249 reversed(range(a, b, c)) with large arguments.

1387 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
1388 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00001389 to match the behaviour of the other integer format codes.

1417 allocator will be automatically disabled when running under Valgrind. This
1418 gives improved memory leak detection when running under Valgrind, while taking
1419 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00001492- The default size of the re module's compiled regular expression cache has been
1493 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00001494 simply clearing the entire cache on overflow to forgetting the least recently
1495 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00001496 applications that use a lot of regular expressions and limits the impact of
1497 the performance hit anytime the cache is exceeded.

1510 module is renamed to `_datetime` and if available, overrides all classes
1511 defined in datetime with fast C impementation. Python implementation is based
1512 on the original python prototype for the datetime module by Tim Peters with
1513 minor modifications by the PyPy project. The test suite now tests `datetime`
1514 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00001928- Comparisons using one of <, <=, >, >= between a complex instance and a
1929 Fractions instance now raise TypeError instead of returning True/False. This
1930 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1931 <=> complex, and complex <=> complex comparisons.

Antoine Pitrou910bd512010-03-22 20:11:09 +00001940- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00001941 didn't support chflags() (for example ZFS under FreeBSD). The error is now

1976 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00001977
Georg Brandl62069d32010-07-31 08:56:11 +00001978- subprocess.Popen now has restore_signals and start_new_session features. The
1979 default of restore_signals=True is a new behavior compared to earlier Python
1980 versions. This means that signals such as SIGPIPE are not ignored by default
1981 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00001982

Georg Brandl62069d32010-07-31 08:56:11 +00002067- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
2068 position when calling `truncate()`. It would previously change the file
2069 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00002070 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2071
Antoine Pitroua32f9a22010-01-27 21:18:57 +00002072- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00002073 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
2074 archive. The new implementation is significantly faster and can be wrapped in
2075 a :class:`io.BufferedReader` object for more speedups. It also solves an
2076 issue where interleaved calls to `read()` and `readline()` give wrong results.
2077 Patch by Nir Aides.

Brett Cannon69194272009-07-20 04:23:48 +00002412- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00002413 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
2414 PyPycLoader inherit from this class and provide implementations in relation to
2415 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00002416
Brett Cannon64ef00f2009-07-20 03:19:18 +00002417- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
2418 the documentation said it did even though the code in PyLoader relied on the
2419 abstract method required by ResourceLoader.
2420
Georg Brandl62069d32010-07-31 08:56:11 +00002421- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00002469- Issue #9959: Tweak formula used for computing math.log of an integer,
2470 making it marginally more accurate for exact powers of 2.
2471
Mark Dickinsoncf28b952010-07-29 21:41:59 +00002472- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
2473
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00002474- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00002475 compared to other unix systems. In particular, os.getgroups() does not reflect
2476 any changes made using os.setgroups() but basicly always returns the same
2477 information as the id command. os.getgroups() can now return more than 16
2478 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00002479

2483 struct.pack('>?')): if conversion to bool raised an exception then that
2484 exception wasn't properly propagated on machines where char is unsigned.
Mark Dickinsone26660f2010-07-18 07:48:20 +00002485
Georg Brandl62069d32010-07-31 08:56:11 +00002486- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x python when
2487 they contain instances of old-style classes.
Alexander Belopolskyd92f0402010-07-17 22:50:45 +00002488
Georg Brandl62069d32010-07-31 08:56:11 +00002489- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to accompany

2499
Benjamin Petersonf751bc92010-07-02 13:46:42 +00002500- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
2501 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00002502
Georg Brandl62069d32010-07-31 08:56:11 +00002503- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
2504 Prior to this change, timezone adjustment in utctimetuple() could produce
2505 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
2506 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00002508- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
2509 directive. When the ``%z`` directive is present in the format string, an
2510 aware ``datetime`` object is returned with ``tzinfo`` bound to a
2511 ``datetime.timezone`` instance constructed from the parsed offset. If both
2512 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
2513 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00002514
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00002515- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00002516 implementing ``datetime.tzinfo`` interface. Instances of the new class,
2517 ``datetime.timezone``, return fixed name and UTC offset from their
2518 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
2519 returns ``None``. A class attribute, ``utc`` contains an instance
2520 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00002536- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
2537 with an improved 'binary-split' algorithm that uses fewer multiplications and
2538 allows many of the multiplications to be performed using plain C integer
2539 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
2540 arguments.

2544
Mark Dickinson0381e3f2010-05-08 14:35:02 +00002545- Issue #8644: The accuracy of td.total_seconds() has been improved (by
2546 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00002547 the result is now always correctly rounded, and is equivalent to ``td /
2548 timedelta(seconds=1)``.

2557 integer format code, struct.pack first attempts to convert the non-integer
2558 using its __index__ method. If that method is non-existent or raises
2559 TypeError it goes on to try the __int__ method, as described below.

3139 to be like 'g' but with at least one decimal point and with a
3140 default precision of 12. Previously, the behavior the same but with
3141 a default precision of 6. This more closely matches str(), and
3142 reduces surprises when adding alignment flags to the empty
3143 presentation type. This also affects the new complex.__format__ in
3144 the same way.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00003187- Issue #1869 (and many duplicates): make round(x, n) correctly
3188 rounded for a float x, by using the decimal <-> binary conversions
3189 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
3190 consistently agrees with format(x, '.2f').
3191
Benjamin Petersonae937c02009-04-18 20:54:08 +00003192- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith35e84722009-04-16 20:21:28 +00003197- Issue #5515: str.format() type 'n' combined with commas and leading
3198 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00003199
3200- Implement PEP 378, Format Specifier for Thousands Separator, for
3201 floats.
3202
Mark Dickinson3370cce2009-04-17 22:40:53 +00003203- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003204 1e11, not 1e12. This avoids printing 13 significant digits in
3205 situations where only 12 of them are correct. Example problem
3206 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
3207 long time.)
3208
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003209- Issue #1580: On most platforms, use a 'short' float repr: for a
3210 finite float x, repr(x) now outputs a string based on the shortest
3211 sequence of decimal digits that rounds to x. Previous behaviour was
3212 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00003213 Another minor difference is that the new repr switches to
3214 exponential notation at 1e16 instead of the previous 1e17; this
3215 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003216
3217 There's a new sys attribute sys.float_repr_style, which takes
3218 the value 'short' to indicate that we're using short float repr,
3219 and 'legacy' if the short float repr isn't available for one
3220 reason or another.
3221
3222 The float repr change involves incorporating David Gay's 'perfect
3223 rounding' code into the Python core (it's in Python/dtoa.c). As a
3224 secondary consequence, all string-to-float and float-to-string
3225 conversions (including all float formatting operations) will be
3226 correctly rounded on these platforms.
3227
Georg Brandl5f90d792010-08-01 22:31:05 +00003228 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003229 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00003231- Issue #5759: float() didn't call __float__ on str subclasses.
3232
Georg Brandlabc38772009-04-12 15:51:51 +00003233- The string.maketrans() function is deprecated; there is a new static method
3234 maketrans() on the bytes and bytearray classes. This removes confusion about
3235 the types string.maketrans() is supposed to work with, and mirrors the
3236 methods available on the str class.
3237
R. David Murraydc6da8a2009-04-09 22:16:43 +00003238- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

3528 rotating the object pointer by 4 bits to the right.
3529
Mark Dickinson87ec0852009-02-09 17:15:59 +00003530- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
3531 it now forces its argument to double before testing for infinity.
3532
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00003533- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
3534 returns a non-number type.
3535
Benjamin Peterson87618552009-02-08 15:00:52 +00003536- Issue #5182: Removed memoryview.__str__.
3537
Mark Dickinsonc008a172009-02-01 13:59:22 +00003538- Issue #1717: Removed builtin cmp() function, dropped tp_compare
3539 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00003540 the type definition cmpfunc. The tp_compare slot has been renamed

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00003542
Georg Brandl1cdd83c2009-04-05 20:24:29 +00003543- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00003544 were suppressing all exceptions. These include list() and bytearray().
3545
Mark Dickinson1124e712009-01-28 21:25:58 +00003546- Issue #4707: round(x, n) now returns an integer if x is an integer.
3547 Previously it returned a float.
3548
Antoine Pitroub52ec782009-01-25 16:34:23 +00003549- Issue #4753: By enabling a configure option named '--with-computed-gotos'
3550 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
3551 evaluation loop is compiled with a new dispatch mechanism which gives
3552 speedups of up to 20%, depending on the system, on various benchmarks.
3553
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00003554- Issue #4874: Most builtin decoders now reject unicode input.

3560
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00003561- Issue #4838: When a module is deallocated, free the memory backing the
3562 optional module state data.
3563
Mark Dickinson8055afd2009-01-17 10:04:45 +00003564- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003565 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00003566
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00003567- Issue #4935: The overflow checking code in the expandtabs() method common
3568 to str, bytes and bytearray could be optimized away by the compiler, letting
3569 the interpreter segfault instead of raising an error.
3570
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00003571- Issue #3720: Fix a crash when an iterator modifies its class and removes its
3572 __next__ method.
3573
Mark Dickinsone5e298f2009-01-12 20:49:19 +00003574- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
3575 function no longer attempt to call the __long__ slot to convert an object
3576 to an integer. Only the __int__ and __trunc__ slots are examined.
3577
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00003578- Issue #4893: Use NT threading on CE.
3579

3581
Antoine Pitrouab868312009-01-10 15:40:25 +00003582- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
3583 common cases are optimized thanks to a dedicated fast path and a moderate
3584 amount of loop unrolling.
3585
Antoine Pitrou14b78f52009-01-09 22:27:08 +00003586- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
3587 collecting the oldest generation) so that allocating lots of objects without
3588 destroying them does not show quadratic performance. Based on a proposal by
3589 Martin von Löwis at
3590 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
3591
Vinay Sajip6268cbc2009-01-21 00:19:28 +00003592- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00003593 having been closed (for instance, a read() call could return some
3594 previously buffered data). Patch by Dmitry Vasiliev.
3595
Antoine Pitrou05608432009-01-09 18:53:14 +00003596- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
3597 flag to work properly. Furthermore, when specifying -u, the text stdout
3598 and stderr streams have line-by-line buffering enabled (the default being
3599 to buffer arbitrary chunks of data).
3600
Raymond Hettinger35631532009-01-09 03:58:09 +00003601- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
3602 instead of ints (reducing its size from 4 to 8 times thereby reducing
3603 Python's overall memory).
3604
Antoine Pitroud35cbf62009-01-06 19:02:24 +00003605- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
3606 an existing .py counterpart, override the co_filename attributes of all
3607 code objects if the original filename is obsolete (which can happen if the
3608 file has been renamed, moved, or if it is accessed through different paths).
3609 Patch by Ziga Seilnacht and Jean-Paul Calderone.
3610
Antoine Pitrouc3b39242009-01-03 16:59:18 +00003611- Issue #4580: Fix slicing of memoryviews when the item size is greater than
3612 one byte. Also fixes the meaning of len() so that it returns the number of
3613 items, rather than the size in bytes.
3614
Martin v. Löwis5c88d812009-01-02 20:47:48 +00003615- Issue #4075: Use OutputDebugStringW in Py_FatalError.
3616
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00003617- Issue #4747: When the terminal does not use utf-8, executing a script with
3618 non-ascii characters in its name could fail with a "SyntaxError: None" error.
3619
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003620- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
3621 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00003622
Antoine Pitrou7ddda782009-01-01 15:35:33 +00003623- Issue #3680: Reference cycles created through a dict, set or deque iterator
3624 did not get collected.
3625
Nick Coghlanf1f2f682008-12-30 07:29:12 +00003626- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
3627 where the tp_hash and tp_dict slots are both NULL.
3628
Georg Brandlccc47b62008-12-28 11:44:14 +00003629- Issue #4759: None is now allowed as the first argument of
3630 bytearray.translate(). It was always allowed for bytes.translate().
3631
Skip Montanaro80072cb2008-12-23 03:51:14 +00003632- Added test case to ensure attempts to read from a file opened for writing
3633 fail.
3634
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00003635- Issue #3106: Speedup some comparisons (str/str and int/int).

3638 comprehensions. Original patch for list comprehensions by Neal Norwitz.
3639
Antoine Pitrou621601a2008-12-17 23:18:19 +00003640- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
3641 print elapsed times, not only when some objects are uncollectable /
3642 unreachable. Original patch by Neil Schemenauer.
3643
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00003644- Issue #3439: Add a bit_length method to int.
3645
Mark Dickinsonda2706b2008-12-11 18:03:03 +00003646- Issue #2173: When getting device encoding, check that return value of
3647 nl_langinfo is not the empty string. This was causing silent build
3648 failures on OS X.
3649
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00003650- Issue #4597: Fixed several opcodes that weren't always propagating
3651 exceptions.
3652
3653- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00003654 context manager returns a value that cannot be converted to a bool.
3655
Mark Dickinsonfd24b322008-12-06 15:33:31 +00003656- Issue #4445: Replace "sizeof(PyBytesObject)" with
3657 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
3658 bytes instances. On a typical machine this saves 3 bytes of memory
3659 (on average) per allocation of a bytes instance.
3660
Christian Heimesa872de52008-12-05 08:26:55 +00003661- Issue #4533: File read operation was dreadfully slow due to a slowly
3662 growing read buffer. Fixed by using the same growth rate algorithm as
3663 Python 2.x.
3664
Antoine Pitrou5504e892008-12-06 21:27:53 +00003665- Issue #4509: Various issues surrounding resize of bytearray objects to
3666 which there are buffer exports (e.g. memoryview instances).
3667
Georg Brandlf9734072008-12-07 15:30:06 +00003668- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
3669 method on file objects with closefd=False. The file descriptor is still
3670 kept open but the file object behaves like a closed file. The ``FileIO``
3671 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00003672
Antoine Pitroubc420402008-12-07 20:14:49 +00003673- Issue #4569: Interpreter crash when mutating a memoryview with an item size
3674 larger than 1.

3679
Walter Dörwaldc1651a02009-05-03 22:55:55 +00003680- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
3681 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3682 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3683 of using the replace error handler in PyUnicode_DecodeUTF8().
