Ned Deily657b2de2011-06-28 19:51:30 -0700430- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
431 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
432 interpreter process. This could cause failures in non-Distutils subprocesses
433 and was unreliable since tests or user programs could modify the interpreter
434 environment after Distutils set it. Instead, have Distutils set the the
435 deployment target only in the environment of each build subprocess. It is
436 still possible to globally override the default by setting
437 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
438 greater or equal to the default value, the value with which the interpreter
439 was built.

Victor Stinner4ee65a92011-01-22 10:30:29 +00001160 filenames, at bootstrap, if the codec registry is not ready yet. It is still
1161 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +00001162 for all file entries in the ZIP file.

1171
Armin Ronacher8d96d772011-01-22 13:13:05 +00001172- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1173 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1174 of HTTP 1.1.
1175
Armin Ronacher59531282011-01-22 13:44:22 +00001176- To match the behaviour of HTTP server, the HTTP client library now also
1177 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1178 that for incoming headers which makes this behaviour now consistent in
1179 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001279- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001280 continuation line in the formatted value has no leading white space and looks
1281 like a header. Since Generator uses Header to format all headers, this check
1282 is made for all headers in any serialized message at serialization time. This
1283 provides protection against header injection attacks.

Éric Araujof0ab5d62011-05-29 03:43:59 +02001292 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001293 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001294
Éric Araujof0ab5d62011-05-29 03:43:59 +02001295- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001296 rfc2047-encoding header values with embedded newlines, leaving them without
1297 folding whitespace. It now uses the continuation_ws, as it does for
1298 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001300- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1301 time.asctime(), time.ctime() and time.strftime() functions will now format
1302 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1303 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1304 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1305 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Antoine Pitrou600232b2011-01-05 21:03:42 +00001316- Issue #7995: When calling accept() on a socket with a timeout, the returned

Georg Brandl27a28582010-10-10 09:49:21 +00002288- ast.literal_eval() can now handle negative numbers. It is also a little more

2319 Py_Initialize().
2320
Georg Brandl27a28582010-10-10 09:49:21 +00002321- All SyntaxErrors now have a column offset and therefore a caret when the error

2326
Nick Coghlan37ee8502010-12-03 14:26:13 +00002327- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00002330- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2331 with a non-empty format string. This is an effort to future-proof user
2332 code. If a derived class does not currently implement __format__ but later
2333 adds its own __format__, it would most likely break user code that had
2334 supplied a format string. This will be changed to a DeprecationWaring in
2335 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002337- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

2339 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002341- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2342 functions from the libc caused the methods .upper() and lower() to become
2343 locale aware and created subtly wrong results.
2344
Georg Brandl27a28582010-10-10 09:49:21 +00002345- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2346 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002347
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002348- Issue #4617: Previously it was illegal to delete a name from the local
2349 namespace if it occurs as a free variable in a nested block. This limitation
2350 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2351
Georg Brandl27a28582010-10-10 09:49:21 +00002352- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2353 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2354 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2355 single character on UCS-2 builds.

2359 memoryview), and gain support for the context management protocol.
2360
Antoine Pitrou079ce542010-09-08 12:37:10 +00002361- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00002390- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002391 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002392 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002393 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002418 retry the select() loop instead of bailing out. This is because select() can
2419 incorrectly report a socket as ready for reading (for example, if it received
2420 some data with an invalid checksum).

Antoine Pitrou6d7df632010-09-27 17:52:25 +00002424- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002425 received. Now sendall() properly calls signal handlers if necessary, and
2426 retries sending if these returned successfully, including on sockets with a
2427 timeout.

Georg Brandl27a28582010-10-10 09:49:21 +00002467 non-blocking mode: they return None when an operation would block (instead of

Georg Brandl27a28582010-10-10 09:49:21 +00002480- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2481 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002500- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002501 it possible for the user to create self-referencing ordered dictionaries which
2502 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002503 approach of using weakref proxies so that reference cycles never get created
2504 in the first place.
2505
Victor Stinnercb043522010-09-10 23:49:04 +00002506- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002510- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2511 environment variable to set the filesystem encoding at Python startup.
2512 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2513 reencode all filenames in all objects.

2524
Georg Brandl27a28582010-10-10 09:49:21 +00002525- Issue #9707: Rewritten reference implementation of threading.local which is
2526 friendlier towards reference cycles. This change is not normally visible
2527 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002529- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2530 still return the id of the parent process after it has exited. This process
2531 id may even have been reused by another unrelated process.
2532
Georg Brandl27a28582010-10-10 09:49:21 +00002533- Issue #9792: In case of connection failure, socket.create_connection() would
2534 swallow the exception and raise a new one, making it impossible to fetch the
2535 original errno, or to filter timeout errors. Now the original error is
2536 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002538- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2539 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2540 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002542- Updates to the random module:
2543
Georg Brandl27a28582010-10-10 09:49:21 +00002544 * Document which parts of the module are guaranteed to stay the same across
2545 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00002547 * Update the seed() method to use all of the bits in a string instead of just
2548 the hash value. This makes better use of the seed value and assures the
2549 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002550
Georg Brandl27a28582010-10-10 09:49:21 +00002551 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2552 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2553 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002554
2555 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002574- hashlib has two new constant attributes: algorithms_guaranteed and
2575 algorithms_avaiable that respectively list the names of hash algorithms
2576 guaranteed to exist in all Python implementations and the names of hash
2577 algorithms available in the current process.
2578
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002579- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002669- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2670 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
2671 bytecode is a bit simplified. Patch by Demur Rumed.
Antoine Pitrou74a69fa2010-09-04 18:43:52 +00002672
Brett Cannonef0e6c32010-09-04 18:24:04 +00002673- Issue #9766: Rename poorly named variables exposed by _warnings to prevent

Georg Brandl649971e2010-09-05 17:06:50 +00002682- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2683 now removed, since their effect was inexistent in 3.x (the default encoding is
2684 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002685
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002686- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
2687 properly. Patch by Stefan Behnel.
2688
Georg Brandl649971e2010-09-05 17:06:50 +00002689- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
2690 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00002691
Benjamin Peterson33856de2010-08-30 14:41:20 +00002692- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
2693
Benjamin Peterson0e102062010-08-25 23:13:17 +00002694- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.

Georg Brandl649971e2010-09-05 17:06:50 +00002696- Issue #9684: Added a definition for SIZEOF_WCHAR_T to PC/pyconfig.h, to match
2697 the pyconfig.h generated by configure on other systems.
Daniel Stutzbach864078a2010-08-25 19:18:59 +00002698
Georg Brandl649971e2010-09-05 17:06:50 +00002699- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that

2704
Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +00002705- Issue #5127: The C functions that access the Unicode Database now accept and
2706 return characters from the full Unicode range, even on narrow unicode builds
2707 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2708 in Python is that unicodedata.numeric() now returns the correct value for
2709 large code points, and repr() may consider more characters as printable.
2710
Victor Stinner6c00c142010-08-17 23:37:11 +00002711- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
2712 as a unicode object, instead of a byte string. Function needed to support
2713 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
2714 function.
2715
Victor Stinner6961bd62010-08-17 22:26:51 +00002716- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

2719
Georg Brandl649971e2010-09-05 17:06:50 +00002720- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
2721 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +00002722

2724 write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
Victor Stinner79766632010-08-16 17:36:42 +00002725 sys.stderr.
2726
Victor Stinner47fcb5b2010-08-13 23:59:58 +00002727- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00002728 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2729 objects are output as-is.
Victor Stinner47fcb5b2010-08-13 23:59:58 +00002730
Georg Brandl649971e2010-09-05 17:06:50 +00002731- Issue #9203: Computed gotos are now enabled by default on supported compilers
2732 (which are detected by the configure script). They can still be disable
2733 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00002734
Georg Brandl649971e2010-09-05 17:06:50 +00002735- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2736 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00002737
Georg Brandl649971e2010-09-05 17:06:50 +00002738- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
2739 array.

Antoine Pitroubddc9fe2010-08-08 20:46:42 +00002742
Georg Brandl649971e2010-09-05 17:06:50 +00002743- Issue #9337: The str() of a float or complex number is now identical to its
2744 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002745
Georg Brandl649971e2010-09-05 17:06:50 +00002746- Issue #9416: Fix some issues with complex formatting where the output with no
2747 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002748
2749 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2750 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3502 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3503 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003504 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003607- The default size of the re module's compiled regular expression cache has been
3608 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003609 simply clearing the entire cache on overflow to forgetting the least recently
3610 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003611 applications that use a lot of regular expressions and limits the impact of
3612 the performance hit anytime the cache is exceeded.

3625 module is renamed to `_datetime` and if available, overrides all classes
3626 defined in datetime with fast C impementation. Python implementation is based
3627 on the original python prototype for the datetime module by Tim Peters with
3628 minor modifications by the PyPy project. The test suite now tests `datetime`
3629 module with and without `_datetime` acceleration using the same test cases.

3856 Patch by Tres Seaver.
3857
Victor Stinnerd17f2192010-08-15 09:56:07 +00003858- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00003859 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00003866- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3867 operation raises multiple signals and more than one of those signals is
3868 trapped, the specification determines the order in which the signals should be
3869 handled. In many cases this order wasn't being followed, leading to the wrong
3870 Python exception being raised.
Mark Dickinsonc69160e2010-05-04 14:35:33 +00003871
Antoine Pitrou6be88762010-05-03 16:48:20 +00003872- Issue #7865: The close() method of :mod:`io` objects should not swallow
Georg Brandl62069d32010-07-31 08:56:11 +00003873 exceptions raised by the implicit flush(). Also qensure that calling close()

Georg Brandl62069d32010-07-31 08:56:11 +00003904- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3905 the method could block indefinitely if called just before the event loop
3906 started running. This also fixes the occasional freezes witnessed in
3907 test_httpservers.
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +00003908
Georg Brandl62069d32010-07-31 08:56:11 +00003909- Issue #8524: When creating an SSL socket, the timeout value of the original
3910 socket wasn't retained (instead, a socket with a positive timeout would be
3911 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00003912
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003913- Issue #5103: SSL handshake would ignore the socket timeout and block
3914 indefinitely if the other end didn't respond.
3915
Georg Brandl62069d32010-07-31 08:56:11 +00003916- The do_handshake() method of SSL objects now adjusts the blocking mode of the
3917 SSL structure if necessary (as other methods already do).
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003918
Georg Brandl62069d32010-07-31 08:56:11 +00003919- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and

Georg Brandl62069d32010-07-31 08:56:11 +00003928- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
3929 string "python" as the *ident*. openlog() arguments are all optional and
3930 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00003931
Georg Brandl62069d32010-07-31 08:56:11 +00003932- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
3933 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00003934 wanting to continue using the socket in clear-text mode, by disabling
3935 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
3936
Antoine Pitrou7062db82010-04-22 13:30:10 +00003937- Issue #8496: make mailcap.lookup() always return a list, rather than an

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003985 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003986 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003987

Georg Brandl62069d32010-07-31 08:56:11 +00003990 Python 2.x and 3.x.
Victor Stinner485fb562010-04-13 11:07:24 +00003991
R. David Murrayb2416e52010-04-12 16:58:02 +00003992- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00003993 filename and date, conforming to the 'standards' they were originally designed
3994 to follow. This improves compatibility with patch tools.
R. David Murrayb2416e52010-04-12 16:58:02 +00003995
R. David Murrayef3d6bd2010-04-12 14:48:58 +00003996- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004010- Add functools.total_ordering() and functools.cmp_to_key().
4011
Georg Brandl62069d32010-07-31 08:56:11 +00004012- Issue #8257: The Decimal construct now accepts a float instance directly,
4013 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004014
4015 >>> Decimal(1.1)
4016 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004021- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4022 InvalidOperation instead of returning False. (Comparisons involving a quiet
4023 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4024 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004025
Georg Brandl62069d32010-07-31 08:56:11 +00004026- Issue #2531: Comparison operations between floats and Decimal instances now
4027 return a result based on the numeric values of the operands; previously they
4028 returned an arbitrary result based on the relative ordering of id(float) and
4029 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4030 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004031
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004032- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004034- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004035 argument `-` which tells it to read files to compile from stdin. Each line is
4036 read on demand and the named file is compiled immediately. (Original patch by
4037 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00004043- Comparisons using one of <, <=, >, >= between a complex instance and a
4044 Fractions instance now raise TypeError instead of returning True/False. This
4045 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4046 <=> complex, and complex <=> complex comparisons.

4090 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4091 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004092
Georg Brandl62069d32010-07-31 08:56:11 +00004093- subprocess.Popen now has restore_signals and start_new_session features. The
4094 default of restore_signals=True is a new behavior compared to earlier Python
4095 versions. This means that signals such as SIGPIPE are not ignored by default
4096 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00004097

Georg Brandl62069d32010-07-31 08:56:11 +00004182- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
4183 position when calling `truncate()`. It would previously change the file
4184 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004185 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4186
Antoine Pitroua32f9a22010-01-27 21:18:57 +00004187- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00004188 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
4189 archive. The new implementation is significantly faster and can be wrapped in
4190 a :class:`io.BufferedReader` object for more speedups. It also solves an
4191 issue where interleaved calls to `read()` and `readline()` give wrong results.
4192 Patch by Nir Aides.

Brett Cannon69194272009-07-20 04:23:48 +00004527- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004528 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4529 PyPycLoader inherit from this class and provide implementations in relation to
4530 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004531
Brett Cannon64ef00f2009-07-20 03:19:18 +00004532- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4533 the documentation said it did even though the code in PyLoader relied on the
4534 abstract method required by ResourceLoader.
4535
Georg Brandl62069d32010-07-31 08:56:11 +00004536- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004584- Issue #9959: Tweak formula used for computing math.log of an integer,
4585 making it marginally more accurate for exact powers of 2.
4586
Mark Dickinsoncf28b952010-07-29 21:41:59 +00004587- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
4588
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004589- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004590 compared to other unix systems. In particular, os.getgroups() does not reflect
4591 any changes made using os.setgroups() but basicly always returns the same
4592 information as the id command. os.getgroups() can now return more than 16
4593 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004594
Martin v. Löwisc9e1c7d2010-07-23 12:16:41 +00004595- Issue #6095: Make directory argument to os.listdir optional.

4598 struct.pack('>?')): if conversion to bool raised an exception then that
4599 exception wasn't properly propagated on machines where char is unsigned.
Mark Dickinsone26660f2010-07-18 07:48:20 +00004600

4614
Benjamin Petersonf751bc92010-07-02 13:46:42 +00004615- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as

Georg Brandl62069d32010-07-31 08:56:11 +00004618- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4619 Prior to this change, timezone adjustment in utctimetuple() could produce
4620 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4621 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004623- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4624 directive. When the ``%z`` directive is present in the format string, an
4625 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4626 ``datetime.timezone`` instance constructed from the parsed offset. If both
4627 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4628 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004629
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004630- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004631 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4632 ``datetime.timezone``, return fixed name and UTC offset from their
4633 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4634 returns ``None``. A class attribute, ``utc`` contains an instance
4635 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004651- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4652 with an improved 'binary-split' algorithm that uses fewer multiplications and
4653 allows many of the multiplications to be performed using plain C integer
4654 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4655 arguments.

Mark Dickinson0381e3f2010-05-08 14:35:02 +00004660- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4661 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004662 the result is now always correctly rounded, and is equivalent to ``td /
4663 timedelta(seconds=1)``.

4672 integer format code, struct.pack first attempts to convert the non-integer
4673 using its __index__ method. If that method is non-existent or raises
4674 TypeError it goes on to try the __int__ method, as described below.

Eric Smith63376222009-05-05 14:04:18 +00005252- Issue #5920: For float.__format__, change the behavior with the

5254 to be like 'g' but with at least one decimal point and with a
5255 default precision of 12. Previously, the behavior the same but with
5256 a default precision of 6. This more closely matches str(), and
5257 reduces surprises when adding alignment flags to the empty
5258 presentation type. This also affects the new complex.__format__ in
5259 the same way.
5260
Martin v. Löwis011e8422009-05-05 04:43:17 +00005261- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

5273 received a new method, detach(). detach() disconnects the underlying stream
5274 from the buffer or text IO and returns it.
5275
Mark Dickinson33841c32009-05-01 15:37:04 +00005276- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5277 floats with absolute value over 1e50. Also remove length
5278 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

5299
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005300- Issue #3166: Make int -> float conversions correctly rounded.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00005302- Issue #1869 (and many duplicates): make round(x, n) correctly
5303 rounded for a float x, by using the decimal <-> binary conversions
5304 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5305 consistently agrees with format(x, '.2f').
5306
Benjamin Petersonae937c02009-04-18 20:54:08 +00005307- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

5309
Eric Smith0923d1d2009-04-16 20:16:10 +00005310- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5311
Eric Smith35e84722009-04-16 20:21:28 +00005312- Issue #5515: str.format() type 'n' combined with commas and leading
5313 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005314
5315- Implement PEP 378, Format Specifier for Thousands Separator, for
5316 floats.
5317
Mark Dickinson3370cce2009-04-17 22:40:53 +00005318- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005319 1e11, not 1e12. This avoids printing 13 significant digits in
5320 situations where only 12 of them are correct. Example problem
5321 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5322 long time.)
5323
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005324- Issue #1580: On most platforms, use a 'short' float repr: for a
5325 finite float x, repr(x) now outputs a string based on the shortest
5326 sequence of decimal digits that rounds to x. Previous behaviour was
5327 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005328 Another minor difference is that the new repr switches to
5329 exponential notation at 1e16 instead of the previous 1e17; this
5330 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005331
5332 There's a new sys attribute sys.float_repr_style, which takes
5333 the value 'short' to indicate that we're using short float repr,
5334 and 'legacy' if the short float repr isn't available for one
5335 reason or another.
5336
5337 The float repr change involves incorporating David Gay's 'perfect
5338 rounding' code into the Python core (it's in Python/dtoa.c). As a
5339 secondary consequence, all string-to-float and float-to-string
5340 conversions (including all float formatting operations) will be
5341 correctly rounded on these platforms.
5342
Georg Brandl5f90d792010-08-01 22:31:05 +00005343 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005344 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005346- Issue #5759: float() didn't call __float__ on str subclasses.
5347
Georg Brandlabc38772009-04-12 15:51:51 +00005348- The string.maketrans() function is deprecated; there is a new static method
5349 maketrans() on the bytes and bytearray classes. This removes confusion about
5350 the types string.maketrans() is supposed to work with, and mirrors the
5351 methods available on the str class.
5352
R. David Murraydc6da8a2009-04-09 22:16:43 +00005353- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

5520 untrackable objects are not tracked by the garbage collector. This can
5521 reduce the size of collections and therefore the garbage collection overhead
5522 on long-running programs, depending on their particular use of datatypes.

5530 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5531 --enable-big-digits option to configure, which overrides the
5532 default. Add sys.int_info structseq to provide information about
5533 the internal format.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005645- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5646 it now forces its argument to double before testing for infinity.
5647
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005648- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5649 returns a non-number type.
5650
Benjamin Peterson87618552009-02-08 15:00:52 +00005651- Issue #5182: Removed memoryview.__str__.
5652
Mark Dickinsonc008a172009-02-01 13:59:22 +00005653- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5654 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005655 the type definition cmpfunc. The tp_compare slot has been renamed

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005657
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005658- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005659 were suppressing all exceptions. These include list() and bytearray().
5660
Mark Dickinson1124e712009-01-28 21:25:58 +00005661- Issue #4707: round(x, n) now returns an integer if x is an integer.
5662 Previously it returned a float.
5663
Antoine Pitroub52ec782009-01-25 16:34:23 +00005664- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5665 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5666 evaluation loop is compiled with a new dispatch mechanism which gives
5667 speedups of up to 20%, depending on the system, on various benchmarks.
5668
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005669- Issue #4874: Most builtin decoders now reject unicode input.

5677 optional module state data.
5678
Mark Dickinson8055afd2009-01-17 10:04:45 +00005679- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005680 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005681
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005682- Issue #4935: The overflow checking code in the expandtabs() method common
5683 to str, bytes and bytearray could be optimized away by the compiler, letting
5684 the interpreter segfault instead of raising an error.
5685
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005686- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5687 __next__ method.
5688
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005689- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5690 function no longer attempt to call the __long__ slot to convert an object
5691 to an integer. Only the __int__ and __trunc__ slots are examined.
5692
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005693- Issue #4893: Use NT threading on CE.
5694

5696
Antoine Pitrouab868312009-01-10 15:40:25 +00005697- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5698 common cases are optimized thanks to a dedicated fast path and a moderate
5699 amount of loop unrolling.
5700
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005701- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5702 collecting the oldest generation) so that allocating lots of objects without
5703 destroying them does not show quadratic performance. Based on a proposal by
5704 Martin von Löwis at
5705 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5706
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005707- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005708 having been closed (for instance, a read() call could return some
5709 previously buffered data). Patch by Dmitry Vasiliev.
5710
Antoine Pitrou05608432009-01-09 18:53:14 +00005711- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5712 flag to work properly. Furthermore, when specifying -u, the text stdout
5713 and stderr streams have line-by-line buffering enabled (the default being
5714 to buffer arbitrary chunks of data).
5715
Raymond Hettinger35631532009-01-09 03:58:09 +00005716- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5717 instead of ints (reducing its size from 4 to 8 times thereby reducing
5718 Python's overall memory).
5719
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005720- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5721 an existing .py counterpart, override the co_filename attributes of all
5722 code objects if the original filename is obsolete (which can happen if the
5723 file has been renamed, moved, or if it is accessed through different paths).
5724 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5725
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005726- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5727 one byte. Also fixes the meaning of len() so that it returns the number of
5728 items, rather than the size in bytes.
5729
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005730- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5731
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005732- Issue #4747: When the terminal does not use utf-8, executing a script with
5733 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5734
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005735- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5736 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005737
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005738- Issue #3680: Reference cycles created through a dict, set or deque iterator
5739 did not get collected.
5740
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005741- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5742 where the tp_hash and tp_dict slots are both NULL.
5743
Georg Brandlccc47b62008-12-28 11:44:14 +00005744- Issue #4759: None is now allowed as the first argument of
5745 bytearray.translate(). It was always allowed for bytes.translate().
5746
Skip Montanaro80072cb2008-12-23 03:51:14 +00005747- Added test case to ensure attempts to read from a file opened for writing
5748 fail.
5749
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005750- Issue #3106: Speedup some comparisons (str/str and int/int).

5753 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5754
Antoine Pitrou621601a2008-12-17 23:18:19 +00005755- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5756 print elapsed times, not only when some objects are uncollectable /
5757 unreachable. Original patch by Neil Schemenauer.
5758
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005759- Issue #3439: Add a bit_length method to int.
5760
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005761- Issue #2173: When getting device encoding, check that return value of
5762 nl_langinfo is not the empty string. This was causing silent build
5763 failures on OS X.
5764
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005765- Issue #4597: Fixed several opcodes that weren't always propagating
5766 exceptions.
5767
5768- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005769 context manager returns a value that cannot be converted to a bool.
5770
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005771- Issue #4445: Replace "sizeof(PyBytesObject)" with
5772 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5773 bytes instances. On a typical machine this saves 3 bytes of memory
5774 (on average) per allocation of a bytes instance.
5775
Christian Heimesa872de52008-12-05 08:26:55 +00005776- Issue #4533: File read operation was dreadfully slow due to a slowly
5777 growing read buffer. Fixed by using the same growth rate algorithm as
5778 Python 2.x.
5779
Antoine Pitrou5504e892008-12-06 21:27:53 +00005780- Issue #4509: Various issues surrounding resize of bytearray objects to
5781 which there are buffer exports (e.g. memoryview instances).
5782
Georg Brandlf9734072008-12-07 15:30:06 +00005783- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5784 method on file objects with closefd=False. The file descriptor is still
5785 kept open but the file object behaves like a closed file. The ``FileIO``
5786 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005787
Antoine Pitroubc420402008-12-07 20:14:49 +00005788- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5789 larger than 1.

5794
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005795- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5796 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5797 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5798 of using the replace error handler in PyUnicode_DecodeUTF8().
