413 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
414 interpreter process. This could cause failures in non-Distutils subprocesses
415 and was unreliable since tests or user programs could modify the interpreter
416 environment after Distutils set it. Instead, have Distutils set the the
417 deployment target only in the environment of each build subprocess. It is
418 still possible to globally override the default by setting
419 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
420 greater or equal to the default value, the value with which the interpreter
421 was built.

Armin Ronacher59531282011-01-22 13:44:22 +00001158- To match the behaviour of HTTP server, the HTTP client library now also
1159 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1160 that for incoming headers which makes this behaviour now consistent in
1161 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001261- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001262 continuation line in the formatted value has no leading white space and looks
1263 like a header. Since Generator uses Header to format all headers, this check
1264 is made for all headers in any serialized message at serialization time. This
1265 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001266

Éric Araujof0ab5d62011-05-29 03:43:59 +02001274 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001275 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001276
Éric Araujof0ab5d62011-05-29 03:43:59 +02001277- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001278 rfc2047-encoding header values with embedded newlines, leaving them without
1279 folding whitespace. It now uses the continuation_ws, as it does for
1280 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001282- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1283 time.asctime(), time.ctime() and time.strftime() functions will now format
1284 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1285 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1286 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1287 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001919 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002264- Issue #10068: Global objects which have reference cycles with their module's
2265 dict are now cleared again. This causes issue #7140 to appear again.
2266
Victor Stinner257d38f2010-10-09 10:12:11 +00002267- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()

Georg Brandl27a28582010-10-10 09:49:21 +00002270- ast.literal_eval() can now handle negative numbers. It is also a little more
2271 liberal in what it accepts without compromising the safety of the evaluation.
2272 For example, 3j+4 and 3+4+5 are both accepted.

Victor Stinner5593d8a2010-10-02 11:11:27 +00002279- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002280 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002294- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002295 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

2298
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002299- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2300 threads are still running. Instead, reinitialize the GIL on a second call to
2301 Py_Initialize().
2302
Georg Brandl27a28582010-10-10 09:49:21 +00002303- All SyntaxErrors now have a column offset and therefore a caret when the error
2304 is printed.

Brett Cannonbc2eff32010-09-19 21:39:02 +00002306- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2307 module that was imported, but instead gets the module from sys.modules.
2308
Nick Coghlan37ee8502010-12-03 14:26:13 +00002309- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002310 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.

Georg Brandl27a28582010-10-10 09:49:21 +00002312- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2313 with a non-empty format string. This is an effort to future-proof user
2314 code. If a derived class does not currently implement __format__ but later
2315 adds its own __format__, it would most likely break user code that had
2316 supplied a format string. This will be changed to a DeprecationWaring in
2317 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002318
Antoine Pitrou1df15362010-09-13 14:16:46 +00002319- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2320 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2321 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2322
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002323- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2324 functions from the libc caused the methods .upper() and lower() to become
2325 locale aware and created subtly wrong results.
2326
Georg Brandl27a28582010-10-10 09:49:21 +00002327- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2328 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002329
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002330- Issue #4617: Previously it was illegal to delete a name from the local
2331 namespace if it occurs as a free variable in a nested block. This limitation
2332 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2333
Georg Brandl27a28582010-10-10 09:49:21 +00002334- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2335 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2336 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2337 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002338
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002339- Issue #9757: memoryview objects get a release() method to release the
2340 underlying buffer (previously this was only done when deallocating the
2341 memoryview), and gain support for the context management protocol.
2342
Antoine Pitrou079ce542010-09-08 12:37:10 +00002343- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2344 thread-local storage key.

2371
Éric Araujoef777bd2010-10-05 00:04:20 +00002372- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002373 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002374 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002375 replacement for old handle_accept() and avoids the user to call accept()
2376 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00002400 retry the select() loop instead of bailing out. This is because select() can

Antoine Pitrou98b46702010-09-18 22:59:00 +00002448- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002449 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002482- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002483 it possible for the user to create self-referencing ordered dictionaries which
2484 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002485 approach of using weakref proxies so that reference cycles never get created
2486 in the first place.

2494 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2495 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002496
Georg Brandl27a28582010-10-10 09:49:21 +00002497- Issue #9410: Various optimizations to the pickle module, leading to speedups

2506
Georg Brandl27a28582010-10-10 09:49:21 +00002507- Issue #9707: Rewritten reference implementation of threading.local which is
2508 friendlier towards reference cycles. This change is not normally visible
2509 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002510
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002511- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2512 still return the id of the parent process after it has exited. This process
2513 id may even have been reused by another unrelated process.
2514
Georg Brandl27a28582010-10-10 09:49:21 +00002515- Issue #9792: In case of connection failure, socket.create_connection() would
2516 swallow the exception and raise a new one, making it impossible to fetch the
2517 original errno, or to filter timeout errors. Now the original error is
2518 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002520- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2521 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2522 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002524- Updates to the random module:
2525
Georg Brandl27a28582010-10-10 09:49:21 +00002526 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002529 * Update the seed() method to use all of the bits in a string instead of just
2530 the hash value. This makes better use of the seed value and assures the
2531 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002533 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2534 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2535 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002536
2537 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002556- hashlib has two new constant attributes: algorithms_guaranteed and
2557 algorithms_avaiable that respectively list the names of hash algorithms
2558 guaranteed to exist in all Python implementations and the names of hash
2559 algorithms available in the current process.

Georg Brandl62069d32010-07-31 08:56:11 +00003072 start byte and the continuation byte(s) are now considered invalid, instead of
3073 the number of bytes specified by the start byte. E.g.:
3074 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3075 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3076 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3077 returned a single u'\ufffd'.

3121 TypeError instead of giving a DeprecationWarning when a float is parsed using
3122 the 'L' code (for long long). (All other integer codes already raise
3123 TypeError in this case.)

3484 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3485 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003486 to match the behaviour of the other integer format codes.

3514 allocator will be automatically disabled when running under Valgrind. This
3515 gives improved memory leak detection when running under Valgrind, while taking
3516 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003589- The default size of the re module's compiled regular expression cache has been
3590 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003591 simply clearing the entire cache on overflow to forgetting the least recently
3592 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003593 applications that use a lot of regular expressions and limits the impact of
3594 the performance hit anytime the cache is exceeded.

3826 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
3827 file system encoding with the surrogateescape error handler (instead of
3828 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

Georg Brandl62069d32010-07-31 08:56:11 +00003848- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3849 operation raises multiple signals and more than one of those signals is
3850 trapped, the specification determines the order in which the signals should be
3851 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandl62069d32010-07-31 08:56:11 +00003891- Issue #8524: When creating an SSL socket, the timeout value of the original
3892 socket wasn't retained (instead, a socket with a positive timeout would be
3893 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00003894
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003895- Issue #5103: SSL handshake would ignore the socket timeout and block

Georg Brandl62069d32010-07-31 08:56:11 +00003914- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
3915 non-infinite timeout. Also make that method friendlier with applications

Georg Brandl62069d32010-07-31 08:56:11 +00004008- Issue #2531: Comparison operations between floats and Decimal instances now
4009 return a result based on the numeric values of the operands; previously they
4010 returned an arbitrary result based on the relative ordering of id(float) and
4011 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4012 comparisons.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004571- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004572 compared to other unix systems. In particular, os.getgroups() does not reflect
4573 any changes made using os.setgroups() but basicly always returns the same
4574 information as the id command. os.getgroups() can now return more than 16
4575 groups on MacOSX.

4601 Prior to this change, timezone adjustment in utctimetuple() could produce
4602 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

4606 directive. When the ``%z`` directive is present in the format string, an
4607 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4608 ``datetime.timezone`` instance constructed from the parsed offset. If both
4609 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4610 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00004613 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4614 ``datetime.timezone``, return fixed name and UTC offset from their
4615 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4616 returns ``None``. A class attribute, ``utc`` contains an instance
4617 representing the UTC timezone. Original patch by Rafe Kaplan.

4634 with an improved 'binary-split' algorithm that uses fewer multiplications and
4635 allows many of the multiplications to be performed using plain C integer
4636 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

4643 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004644 the result is now always correctly rounded, and is equivalent to ``td /
4645 timedelta(seconds=1)``.

4654 integer format code, struct.pack first attempts to convert the non-integer
4655 using its __index__ method. If that method is non-existent or raises
4656 TypeError it goes on to try the __int__ method, as described below.

5237 default precision of 12. Previously, the behavior the same but with
5238 a default precision of 6. This more closely matches str(), and
5239 reduces surprises when adding alignment flags to the empty
5240 presentation type. This also affects the new complex.__format__ in
5241 the same way.

Mark Dickinsonad476da2009-04-23 19:14:16 +00005279- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5280 z involves nans, infs or negative zeros.
5281
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005282- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005283
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005284- Issue #1869 (and many duplicates): make round(x, n) correctly
5285 rounded for a float x, by using the decimal <-> binary conversions
5286 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5287 consistently agrees with format(x, '.2f').
5288
Benjamin Petersonae937c02009-04-18 20:54:08 +00005289- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

5291
Eric Smith0923d1d2009-04-16 20:16:10 +00005292- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5293
Eric Smith35e84722009-04-16 20:21:28 +00005294- Issue #5515: str.format() type 'n' combined with commas and leading
5295 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005296
5297- Implement PEP 378, Format Specifier for Thousands Separator, for
5298 floats.
5299
Mark Dickinson3370cce2009-04-17 22:40:53 +00005300- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005301 1e11, not 1e12. This avoids printing 13 significant digits in
5302 situations where only 12 of them are correct. Example problem
5303 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5304 long time.)
5305
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005306- Issue #1580: On most platforms, use a 'short' float repr: for a
5307 finite float x, repr(x) now outputs a string based on the shortest
5308 sequence of decimal digits that rounds to x. Previous behaviour was
5309 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005310 Another minor difference is that the new repr switches to
5311 exponential notation at 1e16 instead of the previous 1e17; this
5312 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005313
5314 There's a new sys attribute sys.float_repr_style, which takes
5315 the value 'short' to indicate that we're using short float repr,
5316 and 'legacy' if the short float repr isn't available for one
5317 reason or another.
5318
5319 The float repr change involves incorporating David Gay's 'perfect
5320 rounding' code into the Python core (it's in Python/dtoa.c). As a
5321 secondary consequence, all string-to-float and float-to-string
5322 conversions (including all float formatting operations) will be
5323 correctly rounded on these platforms.
5324
Georg Brandl5f90d792010-08-01 22:31:05 +00005325 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005326 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005328- Issue #5759: float() didn't call __float__ on str subclasses.
5329
Georg Brandlabc38772009-04-12 15:51:51 +00005330- The string.maketrans() function is deprecated; there is a new static method
5331 maketrans() on the bytes and bytearray classes. This removes confusion about
5332 the types string.maketrans() is supposed to work with, and mirrors the
5333 methods available on the str class.
5334
R. David Murraydc6da8a2009-04-09 22:16:43 +00005335- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

5502 untrackable objects are not tracked by the garbage collector. This can
5503 reduce the size of collections and therefore the garbage collection overhead
5504 on long-running programs, depending on their particular use of datatypes.

5512 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5513 --enable-big-digits option to configure, which overrides the
5514 default. Add sys.int_info structseq to provide information about
5515 the internal format.

Lars Gustäbel42e00912009-03-22 20:34:29 +00005574- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5575 forever on incomplete input. That caused tarfile.open() to hang when used
5576 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5577 partial bzip2 compressed data.

5583 '>' alignment characters.
5584
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00005585- The error detection code in FileIO.close() could fail to reflect the `errno`
5586 value, and report it as -1 instead.
5587
Antoine Pitroua28fcfd2009-03-13 23:42:55 +00005588- Issue #5016: FileIO.seekable() could return False if the file position

Mark Dickinsonb40b9472009-03-29 16:58:21 +00005598 struct.error instead of returning b'\xff\xff\xff\xff'. The
5599 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5600 have been removed from the struct module.

5614
Eric Smith5e5c0db2009-02-20 14:25:03 +00005615- Issue #5247: Improve error message when unknown format codes are
5616 used when using str.format() with str, int, and float arguments.
5617
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005618- Issue #5249: time.strftime returned malformed string when format string
5619 contained non ascii character on windows.
5620
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005621- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5622 source has already been decoded into str.
5623
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005624- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5625 rotating the object pointer by 4 bits to the right.
5626
Mark Dickinson87ec0852009-02-09 17:15:59 +00005627- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5628 it now forces its argument to double before testing for infinity.
5629
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005630- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5631 returns a non-number type.
5632
Benjamin Peterson87618552009-02-08 15:00:52 +00005633- Issue #5182: Removed memoryview.__str__.
5634
Mark Dickinsonc008a172009-02-01 13:59:22 +00005635- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5636 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005637 the type definition cmpfunc. The tp_compare slot has been renamed
5638 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005639
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005640- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005641 were suppressing all exceptions. These include list() and bytearray().
5642
Mark Dickinson1124e712009-01-28 21:25:58 +00005643- Issue #4707: round(x, n) now returns an integer if x is an integer.
5644 Previously it returned a float.
5645
Antoine Pitroub52ec782009-01-25 16:34:23 +00005646- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5647 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5648 evaluation loop is compiled with a new dispatch mechanism which gives
5649 speedups of up to 20%, depending on the system, on various benchmarks.
5650
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005651- Issue #4874: Most builtin decoders now reject unicode input.

5657
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005658- Issue #4838: When a module is deallocated, free the memory backing the
5659 optional module state data.
5660
Mark Dickinson8055afd2009-01-17 10:04:45 +00005661- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005662 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005663
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005664- Issue #4935: The overflow checking code in the expandtabs() method common
5665 to str, bytes and bytearray could be optimized away by the compiler, letting
5666 the interpreter segfault instead of raising an error.
5667
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005668- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5669 __next__ method.
5670
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005671- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5672 function no longer attempt to call the __long__ slot to convert an object
5673 to an integer. Only the __int__ and __trunc__ slots are examined.
5674
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005675- Issue #4893: Use NT threading on CE.
5676
Martin v. Löwisec59d042009-01-12 07:59:10 +00005677- Issue #4915: Port sysmodule to Windows CE.
5678
Antoine Pitrouab868312009-01-10 15:40:25 +00005679- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5680 common cases are optimized thanks to a dedicated fast path and a moderate
5681 amount of loop unrolling.
5682
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005683- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5684 collecting the oldest generation) so that allocating lots of objects without
5685 destroying them does not show quadratic performance. Based on a proposal by
5686 Martin von Löwis at
5687 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5688
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005689- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005690 having been closed (for instance, a read() call could return some
5691 previously buffered data). Patch by Dmitry Vasiliev.
5692
Antoine Pitrou05608432009-01-09 18:53:14 +00005693- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5694 flag to work properly. Furthermore, when specifying -u, the text stdout
5695 and stderr streams have line-by-line buffering enabled (the default being
5696 to buffer arbitrary chunks of data).
5697
Raymond Hettinger35631532009-01-09 03:58:09 +00005698- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5699 instead of ints (reducing its size from 4 to 8 times thereby reducing
5700 Python's overall memory).
5701
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005702- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5703 an existing .py counterpart, override the co_filename attributes of all
5704 code objects if the original filename is obsolete (which can happen if the
5705 file has been renamed, moved, or if it is accessed through different paths).
5706 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5707
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005708- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5709 one byte. Also fixes the meaning of len() so that it returns the number of
5710 items, rather than the size in bytes.
5711
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005712- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5713
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005714- Issue #4747: When the terminal does not use utf-8, executing a script with
5715 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5716
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005717- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5718 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005719
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005720- Issue #3680: Reference cycles created through a dict, set or deque iterator
5721 did not get collected.
5722
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005723- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5724 where the tp_hash and tp_dict slots are both NULL.
5725
Georg Brandlccc47b62008-12-28 11:44:14 +00005726- Issue #4759: None is now allowed as the first argument of
5727 bytearray.translate(). It was always allowed for bytes.translate().
5728
Skip Montanaro80072cb2008-12-23 03:51:14 +00005729- Added test case to ensure attempts to read from a file opened for writing
5730 fail.
5731
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005732- Issue #3106: Speedup some comparisons (str/str and int/int).

5736
Antoine Pitrou621601a2008-12-17 23:18:19 +00005737- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5738 print elapsed times, not only when some objects are uncollectable /
5739 unreachable. Original patch by Neil Schemenauer.
5740
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005741- Issue #3439: Add a bit_length method to int.
5742
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005743- Issue #2173: When getting device encoding, check that return value of
5744 nl_langinfo is not the empty string. This was causing silent build
5745 failures on OS X.
5746
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005747- Issue #4597: Fixed several opcodes that weren't always propagating
5748 exceptions.
5749
5750- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005751 context manager returns a value that cannot be converted to a bool.
5752
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005753- Issue #4445: Replace "sizeof(PyBytesObject)" with
5754 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5755 bytes instances. On a typical machine this saves 3 bytes of memory
5756 (on average) per allocation of a bytes instance.
5757
Christian Heimesa872de52008-12-05 08:26:55 +00005758- Issue #4533: File read operation was dreadfully slow due to a slowly
5759 growing read buffer. Fixed by using the same growth rate algorithm as
5760 Python 2.x.
5761
Antoine Pitrou5504e892008-12-06 21:27:53 +00005762- Issue #4509: Various issues surrounding resize of bytearray objects to
5763 which there are buffer exports (e.g. memoryview instances).
5764
Georg Brandlf9734072008-12-07 15:30:06 +00005765- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5766 method on file objects with closefd=False. The file descriptor is still
5767 kept open but the file object behaves like a closed file. The ``FileIO``
5768 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005769
Antoine Pitroubc420402008-12-07 20:14:49 +00005770- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5771 larger than 1.

5776
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005777- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5778 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5779 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5780 of using the replace error handler in PyUnicode_DecodeUTF8().
