16 deallocator calls one of the methods on the type (e.g. when subclassing
17 IOBase). Diagnosis and patch by Davide Rizzo.

142
Ned Deily657b2de2011-06-28 19:51:30 -0700143- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
144 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
145 interpreter process. This could cause failures in non-Distutils subprocesses
146 and was unreliable since tests or user programs could modify the interpreter
147 environment after Distutils set it. Instead, have Distutils set the the
148 deployment target only in the environment of each build subprocess. It is
149 still possible to globally override the default by setting
150 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
151 greater or equal to the default value, the value with which the interpreter
152 was built.

Victor Stinnerf2e439f2011-01-23 00:11:58 +0000871- Issue #10955: zipimport uses ASCII encoding instead of cp437 to decode
Victor Stinner4ee65a92011-01-22 10:30:29 +0000872 filenames, at bootstrap, if the codec registry is not ready yet. It is still
873 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +0000874 for all file entries in the ZIP file.

883
Armin Ronacher8d96d772011-01-22 13:13:05 +0000884- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
885 encoding. This is the preferred encoding of PEP 3333 and the base encoding
886 of HTTP 1.1.
887
Armin Ronacher59531282011-01-22 13:44:22 +0000888- To match the behaviour of HTTP server, the HTTP client library now also
889 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
890 that for incoming headers which makes this behaviour now consistent in
891 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +0000991- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +0000992 continuation line in the formatted value has no leading white space and looks
993 like a header. Since Generator uses Header to format all headers, this check
994 is made for all headers in any serialized message at serialization time. This
995 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +0000996

R. David Murray92532142011-01-07 23:25:30 +00001003- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Éric Araujof0ab5d62011-05-29 03:43:59 +02001004 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001005 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001006
Éric Araujof0ab5d62011-05-29 03:43:59 +02001007- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001008 rfc2047-encoding header values with embedded newlines, leaving them without
1009 folding whitespace. It now uses the continuation_ws, as it does for
1010 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001012- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1013 time.asctime(), time.ctime() and time.strftime() functions will now format
1014 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1015 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1016 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1017 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

2043 with a non-empty format string. This is an effort to future-proof user
2044 code. If a derived class does not currently implement __format__ but later
2045 adds its own __format__, it would most likely break user code that had
2046 supplied a format string. This will be changed to a DeprecationWaring in
2047 Python 3.3 and it will be an error in Python 3.4.

2062 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2063
Georg Brandl27a28582010-10-10 09:49:21 +00002064- Issue #9804: ascii() now always represents unicode surrogate pairs as a single

2066 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2067 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002102- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method

Georg Brandl27a28582010-10-10 09:49:21 +00002104 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002105 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002130 retry the select() loop instead of bailing out. This is because select() can
2131 incorrectly report a socket as ready for reading (for example, if it received
2132 some data with an invalid checksum).

Antoine Pitrou6d7df632010-09-27 17:52:25 +00002136- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002137 received. Now sendall() properly calls signal handlers if necessary, and
2138 retries sending if these returned successfully, including on sockets with a
2139 timeout.

Georg Brandl27a28582010-10-10 09:49:21 +00002179 non-blocking mode: they return None when an operation would block (instead of
2180 raising an exception).

Georg Brandl27a28582010-10-10 09:49:21 +00002192- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2193 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002212- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002213 it possible for the user to create self-referencing ordered dictionaries which
2214 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002215 approach of using weakref proxies so that reference cycles never get created
2216 in the first place.
2217
Victor Stinnercb043522010-09-10 23:49:04 +00002218- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002222- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2223 environment variable to set the filesystem encoding at Python startup.
2224 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2225 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002226
Georg Brandl27a28582010-10-10 09:49:21 +00002227- Issue #9410: Various optimizations to the pickle module, leading to speedups

2236
Georg Brandl27a28582010-10-10 09:49:21 +00002237- Issue #9707: Rewritten reference implementation of threading.local which is
2238 friendlier towards reference cycles. This change is not normally visible
2239 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002241- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2242 still return the id of the parent process after it has exited. This process
2243 id may even have been reused by another unrelated process.
2244
Georg Brandl27a28582010-10-10 09:49:21 +00002245- Issue #9792: In case of connection failure, socket.create_connection() would
2246 swallow the exception and raise a new one, making it impossible to fetch the
2247 original errno, or to filter timeout errors. Now the original error is
2248 re-raised.

2251 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2252 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002254- Updates to the random module:
2255
Georg Brandl27a28582010-10-10 09:49:21 +00002256 * Document which parts of the module are guaranteed to stay the same across
2257 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00002259 * Update the seed() method to use all of the bits in a string instead of just
2260 the hash value. This makes better use of the seed value and assures the
2261 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002262
Georg Brandl27a28582010-10-10 09:49:21 +00002263 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2264 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2265 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002266
2267 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002286- hashlib has two new constant attributes: algorithms_guaranteed and
2287 algorithms_avaiable that respectively list the names of hash algorithms
2288 guaranteed to exist in all Python implementations and the names of hash
2289 algorithms available in the current process.
2290
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002291- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002381- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2382 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
2383 bytecode is a bit simplified. Patch by Demur Rumed.
Antoine Pitrou74a69fa2010-09-04 18:43:52 +00002384
Brett Cannonef0e6c32010-09-04 18:24:04 +00002385- Issue #9766: Rename poorly named variables exposed by _warnings to prevent

Georg Brandl649971e2010-09-05 17:06:50 +00002394- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2395 now removed, since their effect was inexistent in 3.x (the default encoding is
2396 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002397
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002398- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

2400
Georg Brandl649971e2010-09-05 17:06:50 +00002401- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
2402 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00002403
Benjamin Peterson33856de2010-08-30 14:41:20 +00002404- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
2405
Benjamin Peterson0e102062010-08-25 23:13:17 +00002406- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.

Georg Brandl649971e2010-09-05 17:06:50 +00002408- Issue #9684: Added a definition for SIZEOF_WCHAR_T to PC/pyconfig.h, to match
2409 the pyconfig.h generated by configure on other systems.
Daniel Stutzbach864078a2010-08-25 19:18:59 +00002410
Georg Brandl649971e2010-09-05 17:06:50 +00002411- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that

2418 return characters from the full Unicode range, even on narrow unicode builds
2419 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2420 in Python is that unicodedata.numeric() now returns the correct value for
2421 large code points, and repr() may consider more characters as printable.
2422
Victor Stinner6c00c142010-08-17 23:37:11 +00002423- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
2424 as a unicode object, instead of a byte string. Function needed to support
2425 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
2426 function.
2427
Victor Stinner6961bd62010-08-17 22:26:51 +00002428- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

2431
Georg Brandl649971e2010-09-05 17:06:50 +00002432- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
2433 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +00002434

2436 write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
Victor Stinner79766632010-08-16 17:36:42 +00002437 sys.stderr.
2438
Victor Stinner47fcb5b2010-08-13 23:59:58 +00002439- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00002440 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2441 objects are output as-is.
Victor Stinner47fcb5b2010-08-13 23:59:58 +00002442
Georg Brandl649971e2010-09-05 17:06:50 +00002443- Issue #9203: Computed gotos are now enabled by default on supported compilers
2444 (which are detected by the configure script). They can still be disable
2445 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00002446
Georg Brandl649971e2010-09-05 17:06:50 +00002447- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2448 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00002449
Georg Brandl649971e2010-09-05 17:06:50 +00002450- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
2451 array.

Georg Brandl649971e2010-09-05 17:06:50 +00002455- Issue #9337: The str() of a float or complex number is now identical to its
2456 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002457
Georg Brandl649971e2010-09-05 17:06:50 +00002458- Issue #9416: Fix some issues with complex formatting where the output with no
2459 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002460
2461 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2462 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Georg Brandl62069d32010-07-31 08:56:11 +00002802 start byte and the continuation byte(s) are now considered invalid, instead of
2803 the number of bytes specified by the start byte. E.g.:

2805 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2806 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2807 returned a single u'\ufffd'.

3214 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3215 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003216 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003319- The default size of the re module's compiled regular expression cache has been
3320 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003321 simply clearing the entire cache on overflow to forgetting the least recently
3322 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003323 applications that use a lot of regular expressions and limits the impact of
3324 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003336- Issue #7989: Added pure python implementation of the `datetime` module. The C
3337 module is renamed to `_datetime` and if available, overrides all classes
3338 defined in datetime with fast C impementation. Python implementation is based
3339 on the original python prototype for the datetime module by Tim Peters with
3340 minor modifications by the PyPy project. The test suite now tests `datetime`
3341 module with and without `_datetime` acceleration using the same test cases.

3569
Victor Stinnerd17f2192010-08-15 09:56:07 +00003570- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00003571 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00003578- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3579 operation raises multiple signals and more than one of those signals is
3580 trapped, the specification determines the order in which the signals should be
3581 handled. In many cases this order wasn't being followed, leading to the wrong
3582 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00003616- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3617 the method could block indefinitely if called just before the event loop
3618 started running. This also fixes the occasional freezes witnessed in

Georg Brandl62069d32010-07-31 08:56:11 +00003621- Issue #8524: When creating an SSL socket, the timeout value of the original
3622 socket wasn't retained (instead, a socket with a positive timeout would be
3623 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00003624
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003625- Issue #5103: SSL handshake would ignore the socket timeout and block
3626 indefinitely if the other end didn't respond.
3627
Georg Brandl62069d32010-07-31 08:56:11 +00003628- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00003640- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
3641 string "python" as the *ident*. openlog() arguments are all optional and
3642 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00003643
Georg Brandl62069d32010-07-31 08:56:11 +00003644- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
3645 non-infinite timeout. Also make that method friendlier with applications

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003697 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003698 relies on the system threading library, so as to avoid a semi-busy wait loop.

R. David Murrayb2416e52010-04-12 16:58:02 +00003704- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00003705 filename and date, conforming to the 'standards' they were originally designed

Georg Brandl62069d32010-07-31 08:56:11 +00003733- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3734 InvalidOperation instead of returning False. (Comparisons involving a quiet
3735 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3736 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003737
Georg Brandl62069d32010-07-31 08:56:11 +00003738- Issue #2531: Comparison operations between floats and Decimal instances now
3739 return a result based on the numeric values of the operands; previously they
3740 returned an arbitrary result based on the relative ordering of id(float) and
3741 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3742 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003743
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003744- Added a subtract() method to collections.Counter().

Georg Brandl62069d32010-07-31 08:56:11 +00003747 argument `-` which tells it to read files to compile from stdin. Each line is

Georg Brandl62069d32010-07-31 08:56:11 +00003755- Comparisons using one of <, <=, >, >= between a complex instance and a
3756 Fractions instance now raise TypeError instead of returning True/False. This
3757 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3758 <=> complex, and complex <=> complex comparisons.

Antoine Pitrou910bd512010-03-22 20:11:09 +00003767- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00003768 didn't support chflags() (for example ZFS under FreeBSD). The error is now

3802 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3803 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003804
Georg Brandl62069d32010-07-31 08:56:11 +00003805- subprocess.Popen now has restore_signals and start_new_session features. The
3806 default of restore_signals=True is a new behavior compared to earlier Python
3807 versions. This means that signals such as SIGPIPE are not ignored by default
3808 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00003809

Georg Brandl62069d32010-07-31 08:56:11 +00003894- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
3895 position when calling `truncate()`. It would previously change the file
3896 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00003897 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3898
Antoine Pitroua32f9a22010-01-27 21:18:57 +00003899- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00003900 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
3901 archive. The new implementation is significantly faster and can be wrapped in
3902 a :class:`io.BufferedReader` object for more speedups. It also solves an
3903 issue where interleaved calls to `read()` and `readline()` give wrong results.
3904 Patch by Nir Aides.

Brett Cannon69194272009-07-20 04:23:48 +00004239- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004240 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4241 PyPycLoader inherit from this class and provide implementations in relation to
4242 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004243
Brett Cannon64ef00f2009-07-20 03:19:18 +00004244- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4245 the documentation said it did even though the code in PyLoader relied on the
4246 abstract method required by ResourceLoader.
4247
Georg Brandl62069d32010-07-31 08:56:11 +00004248- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004296- Issue #9959: Tweak formula used for computing math.log of an integer,
4297 making it marginally more accurate for exact powers of 2.
4298
Mark Dickinsoncf28b952010-07-29 21:41:59 +00004299- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
4300
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004301- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004302 compared to other unix systems. In particular, os.getgroups() does not reflect
4303 any changes made using os.setgroups() but basicly always returns the same
4304 information as the id command. os.getgroups() can now return more than 16
4305 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004306
Martin v. Löwisc9e1c7d2010-07-23 12:16:41 +00004307- Issue #6095: Make directory argument to os.listdir optional.

4310 struct.pack('>?')): if conversion to bool raised an exception then that
4311 exception wasn't properly propagated on machines where char is unsigned.
Mark Dickinsone26660f2010-07-18 07:48:20 +00004312
Georg Brandl62069d32010-07-31 08:56:11 +00004313- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x python when
4314 they contain instances of old-style classes.
Alexander Belopolskyd92f0402010-07-17 22:50:45 +00004315
Georg Brandl62069d32010-07-31 08:56:11 +00004316- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to accompany

4326
Benjamin Petersonf751bc92010-07-02 13:46:42 +00004327- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
4328 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00004329
Georg Brandl62069d32010-07-31 08:56:11 +00004330- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4331 Prior to this change, timezone adjustment in utctimetuple() could produce
4332 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4333 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004335- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4336 directive. When the ``%z`` directive is present in the format string, an
4337 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4338 ``datetime.timezone`` instance constructed from the parsed offset. If both
4339 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4340 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004341
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004342- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004343 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4344 ``datetime.timezone``, return fixed name and UTC offset from their
4345 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4346 returns ``None``. A class attribute, ``utc`` contains an instance
4347 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004363- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4364 with an improved 'binary-split' algorithm that uses fewer multiplications and
4365 allows many of the multiplications to be performed using plain C integer
4366 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4367 arguments.

4371
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004372- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4373 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004374 the result is now always correctly rounded, and is equivalent to ``td /
4375 timedelta(seconds=1)``.

Mark Dickinsonc5935772010-04-03 15:54:36 +00004383- Issue #8300: When passing a non-integer argument to struct.pack with any
4384 integer format code, struct.pack first attempts to convert the non-integer
4385 using its __index__ method. If that method is non-existent or raises
4386 TypeError it goes on to try the __int__ method, as described below.
4387

4966 to be like 'g' but with at least one decimal point and with a
4967 default precision of 12. Previously, the behavior the same but with
4968 a default precision of 6. This more closely matches str(), and
4969 reduces surprises when adding alignment flags to the empty
4970 presentation type. This also affects the new complex.__format__ in
4971 the same way.

5011
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005012- Issue #3166: Make int -> float conversions correctly rounded.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00005014- Issue #1869 (and many duplicates): make round(x, n) correctly
5015 rounded for a float x, by using the decimal <-> binary conversions
5016 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5017 consistently agrees with format(x, '.2f').
5018
Benjamin Petersonae937c02009-04-18 20:54:08 +00005019- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith0923d1d2009-04-16 20:16:10 +00005022- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5023
Eric Smith35e84722009-04-16 20:21:28 +00005024- Issue #5515: str.format() type 'n' combined with commas and leading
5025 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005026
5027- Implement PEP 378, Format Specifier for Thousands Separator, for
5028 floats.
5029
Mark Dickinson3370cce2009-04-17 22:40:53 +00005030- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005031 1e11, not 1e12. This avoids printing 13 significant digits in
5032 situations where only 12 of them are correct. Example problem
5033 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5034 long time.)
5035
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005036- Issue #1580: On most platforms, use a 'short' float repr: for a
5037 finite float x, repr(x) now outputs a string based on the shortest
5038 sequence of decimal digits that rounds to x. Previous behaviour was
5039 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005040 Another minor difference is that the new repr switches to
5041 exponential notation at 1e16 instead of the previous 1e17; this
5042 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005043
5044 There's a new sys attribute sys.float_repr_style, which takes
5045 the value 'short' to indicate that we're using short float repr,
5046 and 'legacy' if the short float repr isn't available for one
5047 reason or another.
5048
5049 The float repr change involves incorporating David Gay's 'perfect
5050 rounding' code into the Python core (it's in Python/dtoa.c). As a
5051 secondary consequence, all string-to-float and float-to-string
5052 conversions (including all float formatting operations) will be
5053 correctly rounded on these platforms.
5054
Georg Brandl5f90d792010-08-01 22:31:05 +00005055 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005056 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005058- Issue #5759: float() didn't call __float__ on str subclasses.
5059
Georg Brandlabc38772009-04-12 15:51:51 +00005060- The string.maketrans() function is deprecated; there is a new static method
5061 maketrans() on the bytes and bytearray classes. This removes confusion about
5062 the types string.maketrans() is supposed to work with, and mirrors the
5063 methods available on the str class.
5064
R. David Murraydc6da8a2009-04-09 22:16:43 +00005065- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

5232 untrackable objects are not tracked by the garbage collector. This can
5233 reduce the size of collections and therefore the garbage collection overhead
5234 on long-running programs, depending on their particular use of datatypes.

5242 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5243 --enable-big-digits option to configure, which overrides the
5244 default. Add sys.int_info structseq to provide information about
5245 the internal format.

5305 forever on incomplete input. That caused tarfile.open() to hang when used
5306 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

5346 used when using str.format() with str, int, and float arguments.
5347
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005348- Issue #5249: time.strftime returned malformed string when format string
5349 contained non ascii character on windows.
5350
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005351- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the

5353
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005354- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5355 rotating the object pointer by 4 bits to the right.
5356
Mark Dickinson87ec0852009-02-09 17:15:59 +00005357- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5358 it now forces its argument to double before testing for infinity.
5359
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005360- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5361 returns a non-number type.
5362
Benjamin Peterson87618552009-02-08 15:00:52 +00005363- Issue #5182: Removed memoryview.__str__.
5364
Mark Dickinsonc008a172009-02-01 13:59:22 +00005365- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5366 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005367 the type definition cmpfunc. The tp_compare slot has been renamed
5368 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005369
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005370- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005371 were suppressing all exceptions. These include list() and bytearray().
5372
Mark Dickinson1124e712009-01-28 21:25:58 +00005373- Issue #4707: round(x, n) now returns an integer if x is an integer.
5374 Previously it returned a float.
5375
Antoine Pitroub52ec782009-01-25 16:34:23 +00005376- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5377 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5378 evaluation loop is compiled with a new dispatch mechanism which gives
5379 speedups of up to 20%, depending on the system, on various benchmarks.
5380
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005381- Issue #4874: Most builtin decoders now reject unicode input.

5387
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005388- Issue #4838: When a module is deallocated, free the memory backing the
5389 optional module state data.
5390
Mark Dickinson8055afd2009-01-17 10:04:45 +00005391- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005392 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005393
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005394- Issue #4935: The overflow checking code in the expandtabs() method common
5395 to str, bytes and bytearray could be optimized away by the compiler, letting
5396 the interpreter segfault instead of raising an error.
5397
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005398- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5399 __next__ method.
5400
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005401- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5402 function no longer attempt to call the __long__ slot to convert an object
5403 to an integer. Only the __int__ and __trunc__ slots are examined.
5404
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005405- Issue #4893: Use NT threading on CE.
5406
Martin v. Löwisec59d042009-01-12 07:59:10 +00005407- Issue #4915: Port sysmodule to Windows CE.
5408
Antoine Pitrouab868312009-01-10 15:40:25 +00005409- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5410 common cases are optimized thanks to a dedicated fast path and a moderate
5411 amount of loop unrolling.
5412
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005413- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5414 collecting the oldest generation) so that allocating lots of objects without
5415 destroying them does not show quadratic performance. Based on a proposal by
5416 Martin von Löwis at
5417 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5418
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005419- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005420 having been closed (for instance, a read() call could return some
5421 previously buffered data). Patch by Dmitry Vasiliev.
5422
Antoine Pitrou05608432009-01-09 18:53:14 +00005423- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5424 flag to work properly. Furthermore, when specifying -u, the text stdout
5425 and stderr streams have line-by-line buffering enabled (the default being
5426 to buffer arbitrary chunks of data).
5427
Raymond Hettinger35631532009-01-09 03:58:09 +00005428- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5429 instead of ints (reducing its size from 4 to 8 times thereby reducing
5430 Python's overall memory).
5431
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005432- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5433 an existing .py counterpart, override the co_filename attributes of all
5434 code objects if the original filename is obsolete (which can happen if the
5435 file has been renamed, moved, or if it is accessed through different paths).
5436 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5437
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005438- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5439 one byte. Also fixes the meaning of len() so that it returns the number of
5440 items, rather than the size in bytes.
5441
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005442- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5443
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005444- Issue #4747: When the terminal does not use utf-8, executing a script with
5445 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5446
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005447- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5448 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005449
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005450- Issue #3680: Reference cycles created through a dict, set or deque iterator
5451 did not get collected.
5452
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005453- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5454 where the tp_hash and tp_dict slots are both NULL.
5455
Georg Brandlccc47b62008-12-28 11:44:14 +00005456- Issue #4759: None is now allowed as the first argument of
5457 bytearray.translate(). It was always allowed for bytes.translate().
5458
Skip Montanaro80072cb2008-12-23 03:51:14 +00005459- Added test case to ensure attempts to read from a file opened for writing
5460 fail.
5461
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005462- Issue #3106: Speedup some comparisons (str/str and int/int).

5465 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5466
Antoine Pitrou621601a2008-12-17 23:18:19 +00005467- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5468 print elapsed times, not only when some objects are uncollectable /
5469 unreachable. Original patch by Neil Schemenauer.
5470
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005471- Issue #3439: Add a bit_length method to int.
5472
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005473- Issue #2173: When getting device encoding, check that return value of
5474 nl_langinfo is not the empty string. This was causing silent build
5475 failures on OS X.
5476
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005477- Issue #4597: Fixed several opcodes that weren't always propagating
5478 exceptions.
5479
5480- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005481 context manager returns a value that cannot be converted to a bool.
5482
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005483- Issue #4445: Replace "sizeof(PyBytesObject)" with
5484 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5485 bytes instances. On a typical machine this saves 3 bytes of memory
5486 (on average) per allocation of a bytes instance.
5487
Christian Heimesa872de52008-12-05 08:26:55 +00005488- Issue #4533: File read operation was dreadfully slow due to a slowly
5489 growing read buffer. Fixed by using the same growth rate algorithm as
5490 Python 2.x.
5491
Antoine Pitrou5504e892008-12-06 21:27:53 +00005492- Issue #4509: Various issues surrounding resize of bytearray objects to
5493 which there are buffer exports (e.g. memoryview instances).
5494
Georg Brandlf9734072008-12-07 15:30:06 +00005495- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5496 method on file objects with closefd=False. The file descriptor is still
5497 kept open but the file object behaves like a closed file. The ``FileIO``
5498 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005499
Antoine Pitroubc420402008-12-07 20:14:49 +00005500- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5501 larger than 1.

5506
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005507- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5508 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5509 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5510 of using the replace error handler in PyUnicode_DecodeUTF8().
