12
Antoine Pitrou5136ac02012-01-13 18:52:16 +010013- Issue #13645: pyc files now contain the size of the corresponding source
14 code, to avoid timestamp collisions (especially on filesystems with a low
15 timestamp resolution) when checking for freshness of the bytecode.
16
Nick Coghlan1f7ce622012-01-13 21:43:40 +100017- PEP 380, Issue #11682: Add "yield from <x>" to support easy delegation to
18 subgenerators (initial patch by Greg Ewing, integration into 3.3 by
19 Renaud Blanch, Ryan Kelly, Zbigniew Jędrzejewski-Szmek and Nick Coghlan)
20
Antoine Pitrou3a5d4cb2012-01-12 22:46:19 +010021- Issue #13748: Raw bytes literals can now be written with the ``rb`` prefix
22 as well as ``br``.

34 objects. Initial patch by Matthias Troffaes.
35
Antoine Pitroue0e27352011-12-15 14:31:28 +010036- Fix OSError.__init__ and OSError.__new__ so that each of them can be
37 overriden and take additional arguments (followup to issue #12555).
38
Antoine Pitrou2e872082011-12-15 14:15:31 +010039- Fix the fix for issue #12149: it was incorrect, although it had the side
40 effect of appearing to resolve the issue. Thanks to Mark Shannon for
41 noticing.
42

52
Antoine Pitrou11942a52011-11-28 19:08:36 +010053- Issue #7111: Python can now be run without a stdin, stdout or stderr

Victor Stinner6345be92011-11-25 20:09:01 +010062 different than "strict" anymore. The caller was unable to compute the
63 size of the output buffer: it depends on the error handler.
64
Antoine Pitrou86a36b52011-11-25 18:56:07 +010065- PEP 3155 / issue #13448: Qualified name for classes and functions.

78 Stefan Behnel.
79
Antoine Pitrou56a220a2011-11-16 00:56:10 +010080- Issue #13393: BufferedReader.read1() now asks the full requested size to
81 the raw stream instead of limiting itself to the buffer size.
82
Antoine Pitrou28e401e2011-11-15 19:15:19 +010083- Issue #13392: Writing a pyc file should now be atomic under Windows as well.
84
Antoine Pitrou5418ee02011-11-15 01:42:21 +010085- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
86 already accepts them).
87
Antoine Pitrou9a812cb2011-11-15 00:00:12 +010088- Issue #13389: Full garbage collection passes now clear the freelists for
89 list and dict objects. They already cleared other freelists in the
90 interpreter.
91

94 order to update to the current time. Also added keyword argument
95 handling to os.utimensat in order to remove the need for explicit None.
Brian Curtin52fbea12011-11-06 13:41:17 -060096

122 object identity).
123
Nick Coghlande31b192011-10-23 22:04:16 +1000124- Issue #1294232: In a few cases involving metaclass inheritance, the

1055
Ned Deily657b2de2011-06-28 19:51:30 -07001056- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1057 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1058 interpreter process. This could cause failures in non-Distutils subprocesses
1059 and was unreliable since tests or user programs could modify the interpreter
1060 environment after Distutils set it. Instead, have Distutils set the the
1061 deployment target only in the environment of each build subprocess. It is
1062 still possible to globally override the default by setting
1063 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1064 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -07001065 was built. Also, implement the same handling in packaging.

Steven Bethardb0270112011-01-24 21:02:50 +00002215
2216- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00002217 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00002218 that for incoming headers which makes this behaviour now consistent in
2219 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00002315- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00002316 continuation line in the formatted value has no leading white space and looks
2317 like a header. Since Generator uses Header to format all headers, this check
2318 is made for all headers in any serialized message at serialization time. This
2319 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00002320

Georg Brandl255abdd2011-01-16 14:17:26 +00002329 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00002330
Éric Araujof0ab5d62011-05-29 03:43:59 +02002331- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00002332 rfc2047-encoding header values with embedded newlines, leaving them without
2333 folding whitespace. It now uses the continuation_ws, as it does for
2334 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00002336- Issue #1777412, #10827: Changed the rules for 2-digit years. The
2337 time.asctime(), time.ctime() and time.strftime() functions will now format

2339 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
2340 supported by the OS. With Visual Studio or on Solaris, the year is limited to
2341 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002975 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

3324
Victor Stinner257d38f2010-10-09 10:12:11 +00003325- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()

Georg Brandl27a28582010-10-10 09:49:21 +00003328- ast.literal_eval() can now handle negative numbers. It is also a little more
3329 liberal in what it accepts without compromising the safety of the evaluation.
3330 For example, 3j+4 and 3+4+5 are both accepted.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00003352- Issue #9930: Remove bogus subtype check that was causing (e.g.)

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00003357- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other

3359 Py_Initialize().
3360
Georg Brandl27a28582010-10-10 09:49:21 +00003361- All SyntaxErrors now have a column offset and therefore a caret when the error
3362 is printed.

Brett Cannonbc2eff32010-09-19 21:39:02 +00003364- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3365 module that was imported, but instead gets the module from sys.modules.
3366
Nick Coghlan37ee8502010-12-03 14:26:13 +00003367- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00003370- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3371 with a non-empty format string. This is an effort to future-proof user
3372 code. If a derived class does not currently implement __format__ but later
3373 adds its own __format__, it would most likely break user code that had
3374 supplied a format string. This will be changed to a DeprecationWaring in
3375 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00003376
Antoine Pitrou1df15362010-09-13 14:16:46 +00003377- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3378 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3379 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3380
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003381- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3382 functions from the libc caused the methods .upper() and lower() to become
3383 locale aware and created subtly wrong results.
3384
Georg Brandl27a28582010-10-10 09:49:21 +00003385- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3386 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003387
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003388- Issue #4617: Previously it was illegal to delete a name from the local
3389 namespace if it occurs as a free variable in a nested block. This limitation
3390 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3391
Georg Brandl27a28582010-10-10 09:49:21 +00003392- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3393 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3394 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3395 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00003396
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003397- Issue #9757: memoryview objects get a release() method to release the
3398 underlying buffer (previously this was only done when deallocating the
3399 memoryview), and gain support for the context management protocol.
3400
Antoine Pitrou079ce542010-09-08 12:37:10 +00003401- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3402 thread-local storage key.

3429
Éric Araujoef777bd2010-10-05 00:04:20 +00003430- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003431 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003432 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003433 replacement for old handle_accept() and avoids the user to call accept()
3434 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00003458 retry the select() loop instead of bailing out. This is because select() can

3505
Antoine Pitrou98b46702010-09-18 22:59:00 +00003506- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00003507 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003540- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003541 it possible for the user to create self-referencing ordered dictionaries which
3542 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003543 approach of using weakref proxies so that reference cycles never get created
3544 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00003550- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3551 environment variable to set the filesystem encoding at Python startup.
3552 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3553 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003554
Georg Brandl27a28582010-10-10 09:49:21 +00003555- Issue #9410: Various optimizations to the pickle module, leading to speedups

3564
Georg Brandl27a28582010-10-10 09:49:21 +00003565- Issue #9707: Rewritten reference implementation of threading.local which is
3566 friendlier towards reference cycles. This change is not normally visible
3567 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003568
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003569- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3570 still return the id of the parent process after it has exited. This process
3571 id may even have been reused by another unrelated process.
3572
Georg Brandl27a28582010-10-10 09:49:21 +00003573- Issue #9792: In case of connection failure, socket.create_connection() would
3574 swallow the exception and raise a new one, making it impossible to fetch the
3575 original errno, or to filter timeout errors. Now the original error is
3576 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003578- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3579 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3580 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00003581
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003582- Updates to the random module:
3583
Georg Brandl27a28582010-10-10 09:49:21 +00003584 * Document which parts of the module are guaranteed to stay the same across
3585 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00003587 * Update the seed() method to use all of the bits in a string instead of just
3588 the hash value. This makes better use of the seed value and assures the
3589 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003591 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3592 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3593 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003594
3595 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003614- hashlib has two new constant attributes: algorithms_guaranteed and
3615 algorithms_avaiable that respectively list the names of hash algorithms
3616 guaranteed to exist in all Python implementations and the names of hash
3617 algorithms available in the current process.
3618

Georg Brandl62069d32010-07-31 08:56:11 +00004130 start byte and the continuation byte(s) are now considered invalid, instead of
4131 the number of bytes specified by the start byte. E.g.:
4132 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
4133 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
4134 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
4135 returned a single u'\ufffd'.

4180 the 'L' code (for long long). (All other integer codes already raise
4181 TypeError in this case.)

4208 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00004209 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
4210 (2) The comparison raised an OverflowError for large integers, leading to
4211 unpredictable exceptions when combining integers and complex objects in sets

4542 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4543 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004544 to match the behaviour of the other integer format codes.

4573 gives improved memory leak detection when running under Valgrind, while taking
4574 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00004647- The default size of the re module's compiled regular expression cache has been
4648 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00004649 simply clearing the entire cache on overflow to forgetting the least recently
4650 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004651 applications that use a lot of regular expressions and limits the impact of
4652 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004906- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4907 operation raises multiple signals and more than one of those signals is
4908 trapped, the specification determines the order in which the signals should be
4909 handled. In many cases this order wasn't being followed, leading to the wrong

4950 socket wasn't retained (instead, a socket with a positive timeout would be
4951 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004952
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004953- Issue #5103: SSL handshake would ignore the socket timeout and block

Georg Brandl62069d32010-07-31 08:56:11 +00005066- Issue #2531: Comparison operations between floats and Decimal instances now
5067 return a result based on the numeric values of the operands; previously they
5068 returned an arbitrary result based on the relative ordering of id(float) and

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005629- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005630 compared to other unix systems. In particular, os.getgroups() does not reflect
5631 any changes made using os.setgroups() but basicly always returns the same
5632 information as the id command. os.getgroups() can now return more than 16
5633 groups on MacOSX.

5659 Prior to this change, timezone adjustment in utctimetuple() could produce
5660 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

5664 directive. When the ``%z`` directive is present in the format string, an
5665 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5666 ``datetime.timezone`` instance constructed from the parsed offset. If both
5667 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5668 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005671 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5672 ``datetime.timezone``, return fixed name and UTC offset from their
5673 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5674 returns ``None``. A class attribute, ``utc`` contains an instance
5675 representing the UTC timezone. Original patch by Rafe Kaplan.

5692 with an improved 'binary-split' algorithm that uses fewer multiplications and
5693 allows many of the multiplications to be performed using plain C integer
5694 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

5701 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005702 the result is now always correctly rounded, and is equivalent to ``td /
5703 timedelta(seconds=1)``.

5712 integer format code, struct.pack first attempts to convert the non-integer
5713 using its __index__ method. If that method is non-existent or raises
5714 TypeError it goes on to try the __int__ method, as described below.

6294 to be like 'g' but with at least one decimal point and with a
6295 default precision of 12. Previously, the behavior the same but with
6296 a default precision of 6. This more closely matches str(), and
6297 reduces surprises when adding alignment flags to the empty
6298 presentation type. This also affects the new complex.__format__ in
6299 the same way.

Mark Dickinsonad476da2009-04-23 19:14:16 +00006337- Issue #5816: complex(repr(z)) now recovers z exactly, even when

6339
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006340- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006341
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006342- Issue #1869 (and many duplicates): make round(x, n) correctly
6343 rounded for a float x, by using the decimal <-> binary conversions
6344 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6345 consistently agrees with format(x, '.2f').
6346
Benjamin Petersonae937c02009-04-18 20:54:08 +00006347- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

6349
Eric Smith0923d1d2009-04-16 20:16:10 +00006350- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6351
Eric Smith35e84722009-04-16 20:21:28 +00006352- Issue #5515: str.format() type 'n' combined with commas and leading
6353 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006354
6355- Implement PEP 378, Format Specifier for Thousands Separator, for
6356 floats.
6357
Mark Dickinson3370cce2009-04-17 22:40:53 +00006358- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006359 1e11, not 1e12. This avoids printing 13 significant digits in
6360 situations where only 12 of them are correct. Example problem
6361 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6362 long time.)
6363
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006364- Issue #1580: On most platforms, use a 'short' float repr: for a
6365 finite float x, repr(x) now outputs a string based on the shortest
6366 sequence of decimal digits that rounds to x. Previous behaviour was
6367 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006368 Another minor difference is that the new repr switches to
6369 exponential notation at 1e16 instead of the previous 1e17; this
6370 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006371
6372 There's a new sys attribute sys.float_repr_style, which takes
6373 the value 'short' to indicate that we're using short float repr,
6374 and 'legacy' if the short float repr isn't available for one
6375 reason or another.
6376
6377 The float repr change involves incorporating David Gay's 'perfect
6378 rounding' code into the Python core (it's in Python/dtoa.c). As a
6379 secondary consequence, all string-to-float and float-to-string
6380 conversions (including all float formatting operations) will be
6381 correctly rounded on these platforms.
6382
Georg Brandl5f90d792010-08-01 22:31:05 +00006383 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006384 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006386- Issue #5759: float() didn't call __float__ on str subclasses.
6387
Georg Brandlabc38772009-04-12 15:51:51 +00006388- The string.maketrans() function is deprecated; there is a new static method
6389 maketrans() on the bytes and bytearray classes. This removes confusion about
6390 the types string.maketrans() is supposed to work with, and mirrors the
6391 methods available on the str class.
6392
R. David Murraydc6da8a2009-04-09 22:16:43 +00006393- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

6560 untrackable objects are not tracked by the garbage collector. This can
6561 reduce the size of collections and therefore the garbage collection overhead
6562 on long-running programs, depending on their particular use of datatypes.

6570 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6571 --enable-big-digits option to configure, which overrides the
6572 default. Add sys.int_info structseq to provide information about
6573 the internal format.

Lars Gustäbel42e00912009-03-22 20:34:29 +00006632- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6633 forever on incomplete input. That caused tarfile.open() to hang when used
6634 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6635 partial bzip2 compressed data.
6636
Mark Dickinson79f52032009-03-17 23:12:51 +00006637- Issue #2110: Add support for thousands separator and 'n' type
6638 specifier to Decimal.__format__
6639
Mark Dickinson9c59fe02009-03-17 18:15:08 +00006640- Fix Decimal.__format__ bug that swapped the meanings of the '<' and
6641 '>' alignment characters.
6642
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00006643- The error detection code in FileIO.close() could fail to reflect the `errno`
6644 value, and report it as -1 instead.
6645
Antoine Pitroua28fcfd2009-03-13 23:42:55 +00006646- Issue #5016: FileIO.seekable() could return False if the file position

6655 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00006656 struct.error instead of returning b'\xff\xff\xff\xff'. The
6657 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
6658 have been removed from the struct module.

6674 used when using str.format() with str, int, and float arguments.
6675
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006676- Issue #5249: time.strftime returned malformed string when format string
6677 contained non ascii character on windows.
6678
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006679- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6680 source has already been decoded into str.
6681
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006682- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6683 rotating the object pointer by 4 bits to the right.
6684
Mark Dickinson87ec0852009-02-09 17:15:59 +00006685- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6686 it now forces its argument to double before testing for infinity.
6687
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006688- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6689 returns a non-number type.
6690
Benjamin Peterson87618552009-02-08 15:00:52 +00006691- Issue #5182: Removed memoryview.__str__.
6692
Mark Dickinsonc008a172009-02-01 13:59:22 +00006693- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6694 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006695 the type definition cmpfunc. The tp_compare slot has been renamed
6696 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006697
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006698- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006699 were suppressing all exceptions. These include list() and bytearray().
6700
Mark Dickinson1124e712009-01-28 21:25:58 +00006701- Issue #4707: round(x, n) now returns an integer if x is an integer.
6702 Previously it returned a float.
6703
Antoine Pitroub52ec782009-01-25 16:34:23 +00006704- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6705 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6706 evaluation loop is compiled with a new dispatch mechanism which gives
6707 speedups of up to 20%, depending on the system, on various benchmarks.
6708
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006709- Issue #4874: Most builtin decoders now reject unicode input.

6715
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00006716- Issue #4838: When a module is deallocated, free the memory backing the
6717 optional module state data.
6718
Mark Dickinson8055afd2009-01-17 10:04:45 +00006719- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006720 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006721
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006722- Issue #4935: The overflow checking code in the expandtabs() method common
6723 to str, bytes and bytearray could be optimized away by the compiler, letting
6724 the interpreter segfault instead of raising an error.
6725
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006726- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6727 __next__ method.
6728
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006729- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6730 function no longer attempt to call the __long__ slot to convert an object
6731 to an integer. Only the __int__ and __trunc__ slots are examined.
6732
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006733- Issue #4893: Use NT threading on CE.
6734
Martin v. Löwisec59d042009-01-12 07:59:10 +00006735- Issue #4915: Port sysmodule to Windows CE.
6736
Antoine Pitrouab868312009-01-10 15:40:25 +00006737- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6738 common cases are optimized thanks to a dedicated fast path and a moderate
6739 amount of loop unrolling.
6740
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006741- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6742 collecting the oldest generation) so that allocating lots of objects without
6743 destroying them does not show quadratic performance. Based on a proposal by
6744 Martin von Löwis at
6745 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6746
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006747- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006748 having been closed (for instance, a read() call could return some
6749 previously buffered data). Patch by Dmitry Vasiliev.
6750
Antoine Pitrou05608432009-01-09 18:53:14 +00006751- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6752 flag to work properly. Furthermore, when specifying -u, the text stdout
6753 and stderr streams have line-by-line buffering enabled (the default being
6754 to buffer arbitrary chunks of data).
6755
Raymond Hettinger35631532009-01-09 03:58:09 +00006756- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6757 instead of ints (reducing its size from 4 to 8 times thereby reducing
6758 Python's overall memory).
6759
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006760- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6761 an existing .py counterpart, override the co_filename attributes of all
6762 code objects if the original filename is obsolete (which can happen if the
6763 file has been renamed, moved, or if it is accessed through different paths).
6764 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6765
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006766- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6767 one byte. Also fixes the meaning of len() so that it returns the number of
6768 items, rather than the size in bytes.
6769
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006770- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6771
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006772- Issue #4747: When the terminal does not use utf-8, executing a script with
6773 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6774
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006775- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6776 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006777
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006778- Issue #3680: Reference cycles created through a dict, set or deque iterator
6779 did not get collected.
6780
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006781- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6782 where the tp_hash and tp_dict slots are both NULL.
6783
Georg Brandlccc47b62008-12-28 11:44:14 +00006784- Issue #4759: None is now allowed as the first argument of
6785 bytearray.translate(). It was always allowed for bytes.translate().
6786
Skip Montanaro80072cb2008-12-23 03:51:14 +00006787- Added test case to ensure attempts to read from a file opened for writing
6788 fail.
6789
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006790- Issue #3106: Speedup some comparisons (str/str and int/int).

6794
Antoine Pitrou621601a2008-12-17 23:18:19 +00006795- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6796 print elapsed times, not only when some objects are uncollectable /
6797 unreachable. Original patch by Neil Schemenauer.
6798
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006799- Issue #3439: Add a bit_length method to int.
6800
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006801- Issue #2173: When getting device encoding, check that return value of
6802 nl_langinfo is not the empty string. This was causing silent build
6803 failures on OS X.
6804
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006805- Issue #4597: Fixed several opcodes that weren't always propagating
6806 exceptions.
6807
6808- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006809 context manager returns a value that cannot be converted to a bool.
6810
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006811- Issue #4445: Replace "sizeof(PyBytesObject)" with
6812 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6813 bytes instances. On a typical machine this saves 3 bytes of memory
6814 (on average) per allocation of a bytes instance.
6815
Christian Heimesa872de52008-12-05 08:26:55 +00006816- Issue #4533: File read operation was dreadfully slow due to a slowly
6817 growing read buffer. Fixed by using the same growth rate algorithm as
6818 Python 2.x.
6819
Antoine Pitrou5504e892008-12-06 21:27:53 +00006820- Issue #4509: Various issues surrounding resize of bytearray objects to
6821 which there are buffer exports (e.g. memoryview instances).
6822
Georg Brandlf9734072008-12-07 15:30:06 +00006823- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6824 method on file objects with closefd=False. The file descriptor is still
6825 kept open but the file object behaves like a closed file. The ``FileIO``
6826 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006827
Antoine Pitroubc420402008-12-07 20:14:49 +00006828- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6829 larger than 1.

6834
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006835- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6836 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6837 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6838 of using the replace error handler in PyUnicode_DecodeUTF8().
