Ned Deilycbfb9a52012-06-23 16:02:19 -0700762- Issue #13590: Improve support for OS X Xcode 4:
763 * Try to avoid building Python or extension modules with problematic
764 llvm-gcc compiler.
765 * Since Xcode 4 removes ppc support, extension module builds now
766 check for ppc compiler support and automatically remove ppc and
767 ppc64 archs when not available.
768 * Since Xcode 4 no longer install SDKs in default locations,
769 extension module builds now revert to using installed headers
770 and libs if the SDK used to build the interpreter is not
771 available.
772 * Update ./configure to use better defaults for universal builds;
773 in particular, --enable-universalsdk=yes uses the Xcode default
774 SDK and --with-universal-archs now defaults to "intel" if ppc
775 not available.

Ned Deily99377482012-02-10 13:01:08 +01002132- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2133 Distutils-based packages with C extension modules may fail because
2134 Apple has removed gcc-4.2, the version used to build python.org
2135 64-bit/32-bit Pythons. If the user does not explicitly override
2136 the default C compiler by setting the CC environment variable,
2137 Distutils will now attempt to compile extension modules with clang
2138 if gcc-4.2 is required but not found. Also as a convenience, if
2139 the user does explicitly set CC, substitute its value as the default
2140 compiler in the Distutils LDSHARED configuration variable for OS X.
2141 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2142 SDK, neither of which are available in Xcode 4. This change does not
2143 attempt to override settings to support their use with Xcode 4.)

Ned Deily657b2de2011-06-28 19:51:30 -07002870- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2871 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2872 interpreter process. This could cause failures in non-Distutils subprocesses
2873 and was unreliable since tests or user programs could modify the interpreter
2874 environment after Distutils set it. Instead, have Distutils set the the
2875 deployment target only in the environment of each build subprocess. It is
2876 still possible to globally override the default by setting
2877 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2878 greater or equal to the default value, the value with which the interpreter

4111
Victor Stinnerb3c9e072011-01-04 02:07:34 +00004112- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
4113 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
4114 translates newlines (\r\n => \n).
4115
Victor Stinnerdc555402011-01-04 13:15:39 +00004116- Remove buffer API from stable ABI for now, see #10181.
4117
Victor Stinnere6edec22011-01-04 00:29:35 +00004118- Issue #8651: PyArg_Parse*() functions raise an OverflowError if the file
Amaury Forgeot d'Arca251a852011-01-03 00:19:11 +00004119 doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int
4120 (length bigger than 2^31-1 bytes).
4121
Victor Stinner92be9392010-12-28 00:28:21 +00004122- Issue #9015, #9611: FileIO.readinto(), FileIO.write(), os.write() and
Victor Stinnerc655a722011-07-05 11:31:49 +02004123 stdprinter.write() clamp the length to INT_MAX on Windows.
Victor Stinner92be9392010-12-28 00:28:21 +00004124
4125- Issue #8278: On Windows and with a NTFS filesystem, os.stat() and os.utime()

4127
4128- Issue #10780: PyErr_SetFromWindowsErrWithFilename() and
Georg Brandl8aa7e992010-12-28 18:30:18 +00004129 PyErr_SetExcFromWindowsErrWithFilename() decode the filename from the
4130 filesystem encoding instead of UTF-8.
Raymond Hettinger8ebe27f2010-12-21 19:24:26 +00004131
4132- Issue #10779: PyErr_WarnExplicit() decodes the filename from the filesystem

4142
Georg Brandl255abdd2011-01-16 14:17:26 +00004143- Issue #10916: mmap should not segfault when a file is mapped using 0 as length
4144 and a non-zero offset, and an attempt to read past the end of file is made
4145 (IndexError is raised instead). Patch by Ross Lagerwall.
Antoine Pitrou85f46152011-01-15 16:17:07 +00004146

4148 of "UTF8" in the locale module as the latter is not supported MacOSX and OpenBSD.
4149
Georg Brandl255abdd2011-01-16 14:17:26 +00004150- Issue #10907: Warn OS X 10.6 IDLE users to use ActiveState Tcl/Tk 8.5, rather
4151 than the currently problematic Apple-supplied one, when running with the
4152 64-/32-bit installer variant.
Ned Deily4ce92b22011-01-15 04:37:12 +00004153
Victor Stinner5c23b8e2011-01-14 13:05:21 +00004154- Issue #4953: cgi.FieldStorage and cgi.parse() parse the request as bytes, not
4155 as unicode, and accept binary files. Add encoding and errors attributes to
Victor Stinnerc5982962011-01-14 14:11:45 +00004156 cgi.FieldStorage. Patch written by Pierre Quentel (with many inputs by Glenn
4157 Linderman).
Victor Stinner5c23b8e2011-01-14 13:05:21 +00004158
Georg Brandl255abdd2011-01-16 14:17:26 +00004159- Add encoding and errors arguments to urllib.parse_qs() and urllib.parse_qsl().

Georg Brandl619e7ba2011-01-09 07:38:51 +00004171
R. David Murray5b2d9dd2011-01-09 02:35:24 +00004172- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00004173 continuation line in the formatted value has no leading white space and looks
4174 like a header. Since Generator uses Header to format all headers, this check
4175 is made for all headers in any serialized message at serialization time. This
4176 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00004177
Antoine Pitrou67b212e2011-01-08 09:55:31 +00004178- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

4183
R. David Murray92532142011-01-07 23:25:30 +00004184- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Éric Araujof0ab5d62011-05-29 03:43:59 +02004185 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00004186 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00004187
Éric Araujof0ab5d62011-05-29 03:43:59 +02004188- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00004189 rfc2047-encoding header values with embedded newlines, leaving them without
4190 folding whitespace. It now uses the continuation_ws, as it does for
4191 continuation lines that it creates itself.
R. David Murray6f0022d2011-01-07 21:57:25 +00004192
Victor Stinner3ec899f2011-01-08 16:37:47 +00004193- Issue #1777412, #10827: Changed the rules for 2-digit years. The
4194 time.asctime(), time.ctime() and time.strftime() functions will now format
4195 any year when ``time.accept2dyear`` is False and will accept years >= 1000
4196 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
4197 supported by the OS. With Visual Studio or on Solaris, the year is limited to
4198 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
Alexander Belopolskyc64708a2011-01-07 19:59:19 +00004199
Antoine Pitroue85da7a2011-01-06 18:25:55 +00004200- Issue #7858: Raise an error properly when os.utime() fails under Windows
4201 on an existing file.
4202
Antoine Pitroub715fac2011-01-06 17:17:04 +00004203- Issue #3839: wsgiref should not override a Content-Length header set by

4205
Victor Stinner4bd81722011-01-06 00:49:38 +00004206- Issue #10492: bdb.Bdb.run() only traces the execution of the code, not the
4207 compilation (if the input is a string).
4208
Antoine Pitrou600232b2011-01-05 21:03:42 +00004209- Issue #7995: When calling accept() on a socket with a timeout, the returned

4217
Victor Stinnerc3a51ec2011-01-04 11:00:45 +00004218- Issue #10819: SocketIO.name property returns -1 when its closed, instead of

4222 the input buffer length doesn't fit into an unsigned int (length bigger than
4223 2^32-1 bytes).
4224

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00005182- Issue #10068: Global objects which have reference cycles with their module's
5183 dict are now cleared again. This causes issue #7140 to appear again.
5184
Victor Stinner257d38f2010-10-09 10:12:11 +00005185- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00005186 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00005187
Georg Brandl27a28582010-10-10 09:49:21 +00005188- ast.literal_eval() can now handle negative numbers. It is also a little more
5189 liberal in what it accepts without compromising the safety of the evaluation.
5190 For example, 3j+4 and 3+4+5 are both accepted.

Benjamin Peterson970d1882010-10-02 17:55:47 +00005192- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
5193 result metaclasses can now be ABCs (see #9533).
5194
Victor Stinneraef57e32010-10-02 11:50:49 +00005195- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
5196
Victor Stinner5593d8a2010-10-02 11:11:27 +00005197- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00005198 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

Brett Cannon5305a992010-09-27 21:08:38 +00005206- Issue #7397: Mention that importlib.import_module() is probably what someone

5208
Georg Brandl27a28582010-10-10 09:49:21 +00005209- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
5210 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00005212- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00005213 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00005215- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
5216
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00005217- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
5218 threads are still running. Instead, reinitialize the GIL on a second call to
5219 Py_Initialize().
5220
Georg Brandl27a28582010-10-10 09:49:21 +00005221- All SyntaxErrors now have a column offset and therefore a caret when the error
5222 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00005223
Brett Cannonbc2eff32010-09-19 21:39:02 +00005224- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
5225 module that was imported, but instead gets the module from sys.modules.
5226
Nick Coghlan37ee8502010-12-03 14:26:13 +00005227- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00005228 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00005229
Georg Brandl27a28582010-10-10 09:49:21 +00005230- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5231 with a non-empty format string. This is an effort to future-proof user
5232 code. If a derived class does not currently implement __format__ but later
5233 adds its own __format__, it would most likely break user code that had
5234 supplied a format string. This will be changed to a DeprecationWaring in
5235 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00005236
Antoine Pitrou1df15362010-09-13 14:16:46 +00005237- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
5238 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
5239 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
5240
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00005241- Issue #9210: Configure option --with-wctype-functions was removed. Using the
5242 functions from the libc caused the methods .upper() and lower() to become
5243 locale aware and created subtly wrong results.
5244
Georg Brandl27a28582010-10-10 09:49:21 +00005245- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
5246 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00005247
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00005248- Issue #4617: Previously it was illegal to delete a name from the local
5249 namespace if it occurs as a free variable in a nested block. This limitation
5250 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
5251
Georg Brandl27a28582010-10-10 09:49:21 +00005252- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
5253 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
5254 Also, the "backslashreplace" error handler now joins surrogate pairs into a
5255 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00005256
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00005257- Issue #9757: memoryview objects get a release() method to release the
5258 underlying buffer (previously this was only done when deallocating the
5259 memoryview), and gain support for the context management protocol.
5260
Antoine Pitrou079ce542010-09-08 12:37:10 +00005261- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
5262 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00005278- Issue #4661: email can now parse bytes input and generate either converted

5280
Antoine Pitrou59fdd672010-10-08 10:37:08 +00005281- Issue #1589: Add ssl.match_hostname(), to help implement server identity

5288 gettext.
5289
Éric Araujoef777bd2010-10-05 00:04:20 +00005290- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00005291 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00005292 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00005293 replacement for old handle_accept() and avoids the user to call accept()
5294 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00005317- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00005318 retry the select() loop instead of bailing out. This is because select() can
5319 incorrectly report a socket as ready for reading (for example, if it received
5320 some data with an invalid checksum).

5365
Antoine Pitrou98b46702010-09-18 22:59:00 +00005366- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00005367 non-blocking mode: they return None when an operation would block (instead of
5368 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00005369
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00005370- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Antoine Pitrou328ec742010-09-14 18:37:24 +00005379
Georg Brandl27a28582010-10-10 09:49:21 +00005380- Issue #1552: socket.socketpair() now returns regular socket.socket objects
5381 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00005400- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00005401 it possible for the user to create self-referencing ordered dictionaries which
5402 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00005403 approach of using weakref proxies so that reference cycles never get created
5404 in the first place.
5405
Victor Stinnercb043522010-09-10 23:49:04 +00005406- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
5407 encode the value with filesystem encoding and surrogateescape (instead of

Victor Stinnercb043522010-09-10 23:49:04 +00005409
Georg Brandl27a28582010-10-10 09:49:21 +00005410- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
5411 environment variable to set the filesystem encoding at Python startup.
5412 sys.setfilesystemencoding() creates inconsistencies because it is unable to
5413 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00005414
Georg Brandl27a28582010-10-10 09:49:21 +00005415- Issue #9410: Various optimizations to the pickle module, leading to speedups

Vinay Sajip121a1c42010-09-08 10:46:15 +00005422- Logging: Added QueueHandler class to facilitate logging usage with
5423 multiprocessing.
5424
Georg Brandl27a28582010-10-10 09:49:21 +00005425- Issue #9707: Rewritten reference implementation of threading.local which is
5426 friendlier towards reference cycles. This change is not normally visible
5427 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00005428
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00005429- Issue #6394: os.getppid() is now supported on Windows. Note that it will
5430 still return the id of the parent process after it has exited. This process
5431 id may even have been reused by another unrelated process.
5432
Georg Brandl27a28582010-10-10 09:49:21 +00005433- Issue #9792: In case of connection failure, socket.create_connection() would
5434 swallow the exception and raise a new one, making it impossible to fetch the
5435 original errno, or to filter timeout errors. Now the original error is
5436 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00005438- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
5439 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
5440 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00005441
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00005442- Updates to the random module:
5443
Georg Brandl27a28582010-10-10 09:49:21 +00005444 * Document which parts of the module are guaranteed to stay the same across
5445 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00005447 * Update the seed() method to use all of the bits in a string instead of just
5448 the hash value. This makes better use of the seed value and assures the
5449 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00005450
Georg Brandl27a28582010-10-10 09:49:21 +00005451 * Improved the random()-->integer algorithm used in choice(), shuffle(),
5452 sample(), randrange(), and randint(). Formerly, it used int(n*random())
5453 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00005454
5455 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00005474- hashlib has two new constant attributes: algorithms_guaranteed and
5475 algorithms_avaiable that respectively list the names of hash algorithms
5476 guaranteed to exist in all Python implementations and the names of hash
5477 algorithms available in the current process.
5478

Ezio Melotti57221d02010-07-01 07:32:02 +00005989- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00005990 start byte and the continuation byte(s) are now considered invalid, instead of
5991 the number of bytes specified by the start byte. E.g.:
5992 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
5993 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
5994 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
5995 returned a single u'\ufffd'.

6040 the 'L' code (for long long). (All other integer codes already raise
6041 TypeError in this case.)

Georg Brandl62069d32010-07-31 08:56:11 +00006051 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00006067- Issue #8748: Fix two issues with comparisons between complex and integer
6068 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00006069 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
6070 (2) The comparison raised an OverflowError for large integers, leading to
6071 unpredictable exceptions when combining integers and complex objects in sets
6072 or dicts.

6377
Mark Dickinsone6fc7402010-08-06 18:55:26 +00006378- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
6379 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

6402 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
6403 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00006404 to match the behaviour of the other integer format codes.

6433 gives improved memory leak detection when running under Valgrind, while taking
6434 advantage of pymalloc at other times.

6525 module is renamed to `_datetime` and if available, overrides all classes
6526 defined in datetime with fast C impementation. Python implementation is based
6527 on the original python prototype for the datetime module by Tim Peters with
6528 minor modifications by the PyPy project. The test suite now tests `datetime`
6529 module with and without `_datetime` acceleration using the same test cases.

6744 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
6745 file system encoding with the surrogateescape error handler (instead of
6746 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

6749
Georg Brandl62069d32010-07-31 08:56:11 +00006750- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
6751 messages when accessing undefined class attributes because of the cheap
6752 inheritance with the underlying socket object. The cheap inheritance has been
6753 deprecated.

6756 Patch by Tres Seaver.
6757
Victor Stinnerd17f2192010-08-15 09:56:07 +00006758- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00006759 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00006766- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
6767 operation raises multiple signals and more than one of those signals is
6768 trapped, the specification determines the order in which the signals should be
6769 handled. In many cases this order wasn't being followed, leading to the wrong
6770 Python exception being raised.

6778
Georg Brandl62069d32010-07-31 08:56:11 +00006779- Issue #8354: The siginterrupt setting is now preserved for all signals, not

Georg Brandl62069d32010-07-31 08:56:11 +00006804- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
6805 the method could block indefinitely if called just before the event loop
6806 started running. This also fixes the occasional freezes witnessed in
6807 test_httpservers.

Georg Brandl62069d32010-07-31 08:56:11 +00006809- Issue #8524: When creating an SSL socket, the timeout value of the original
6810 socket wasn't retained (instead, a socket with a positive timeout would be
6811 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00006812
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00006813- Issue #5103: SSL handshake would ignore the socket timeout and block
6814 indefinitely if the other end didn't respond.
6815
Georg Brandl62069d32010-07-31 08:56:11 +00006816- The do_handshake() method of SSL objects now adjusts the blocking mode of the
6817 SSL structure if necessary (as other methods already do).

Georg Brandl62069d32010-07-31 08:56:11 +00006828- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
6829 string "python" as the *ident*. openlog() arguments are all optional and
6830 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00006831
Georg Brandl62069d32010-07-31 08:56:11 +00006832- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
6833 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00006834 wanting to continue using the socket in clear-text mode, by disabling
6835 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00006885 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00006886 relies on the system threading library, so as to avoid a semi-busy wait loop.

R. David Murrayb2416e52010-04-12 16:58:02 +00006892- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00006893 filename and date, conforming to the 'standards' they were originally designed

6915 >>> Decimal(1.1)

Georg Brandl62069d32010-07-31 08:56:11 +00006921- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
6922 InvalidOperation instead of returning False. (Comparisons involving a quiet
6923 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
6924 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00006926- Issue #2531: Comparison operations between floats and Decimal instances now
6927 return a result based on the numeric values of the operands; previously they
6928 returned an arbitrary result based on the relative ordering of id(float) and
6929 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
6930 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00006931
Raymond Hettinger9c01e442010-04-03 10:32:58 +00006932- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00006934- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00006935 argument `-` which tells it to read files to compile from stdin. Each line is

6944 Fractions instance now raise TypeError instead of returning True/False. This
6945 makes Fraction <=> complex comparisons consistent with int <=> complex, float
6946 <=> complex, and complex <=> complex comparisons.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00007087- Issue #7610: Reworked implementation of the internal

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00007489- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00007490 compared to other unix systems. In particular, os.getgroups() does not reflect
7491 any changes made using os.setgroups() but basicly always returns the same
7492 information as the id command. os.getgroups() can now return more than 16
7493 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00007518- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
7519 Prior to this change, timezone adjustment in utctimetuple() could produce
7520 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

7524 directive. When the ``%z`` directive is present in the format string, an
7525 aware ``datetime`` object is returned with ``tzinfo`` bound to a
7526 ``datetime.timezone`` instance constructed from the parsed offset. If both
7527 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
7528 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00007530- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00007531 implementing ``datetime.tzinfo`` interface. Instances of the new class,
7532 ``datetime.timezone``, return fixed name and UTC offset from their
7533 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
7534 returns ``None``. A class attribute, ``utc`` contains an instance
7535 representing the UTC timezone. Original patch by Rafe Kaplan.

7552 with an improved 'binary-split' algorithm that uses fewer multiplications and
7553 allows many of the multiplications to be performed using plain C integer
7554 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00007560- Issue #8644: The accuracy of td.total_seconds() has been improved (by
7561 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00007562 the result is now always correctly rounded, and is equivalent to ``td /
7563 timedelta(seconds=1)``.

7572 integer format code, struct.pack first attempts to convert the non-integer
7573 using its __index__ method. If that method is non-existent or raises
7574 TypeError it goes on to try the __int__ method, as described below.

Mark Dickinson865e01a2009-05-07 16:37:01 +00008141- Issue #5914: Add new C API function PyOS_string_to_double, and
8142 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
8143
Eric Smith741191f2009-05-06 13:08:15 +00008144- Issue #3382: float.__format__, complex.__format__, and %-formatting
8145 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

Eric Smith63376222009-05-05 14:04:18 +00008152- Issue #5920: For float.__format__, change the behavior with the
8153 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
8154 to be like 'g' but with at least one decimal point and with a
8155 default precision of 12. Previously, the behavior the same but with
8156 a default precision of 6. This more closely matches str(), and
8157 reduces surprises when adding alignment flags to the empty
8158 presentation type. This also affects the new complex.__format__ in
8159 the same way.
8160
Martin v. Löwis011e8422009-05-05 04:43:17 +00008161- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

8173 received a new method, detach(). detach() disconnects the underlying stream
8174 from the buffer or text IO and returns it.
8175
Mark Dickinson33841c32009-05-01 15:37:04 +00008176- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
8177 floats with absolute value over 1e50. Also remove length
8178 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

8185 never gives more than the requested number of significant digits.
8186
Eric Smith6dc46f52009-04-27 20:39:49 +00008187- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsone6a076d2009-04-18 11:48:33 +00008202- Issue #1869 (and many duplicates): make round(x, n) correctly
8203 rounded for a float x, by using the decimal <-> binary conversions
8204 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
8205 consistently agrees with format(x, '.2f').
8206
Benjamin Petersonae937c02009-04-18 20:54:08 +00008207- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
8208 some builtin types.
8209
Eric Smith0923d1d2009-04-16 20:16:10 +00008210- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
8211
Eric Smith35e84722009-04-16 20:21:28 +00008212- Issue #5515: str.format() type 'n' combined with commas and leading
8213 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00008214
8215- Implement PEP 378, Format Specifier for Thousands Separator, for
8216 floats.
8217
Mark Dickinson3370cce2009-04-17 22:40:53 +00008218- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008219 1e11, not 1e12. This avoids printing 13 significant digits in
8220 situations where only 12 of them are correct. Example problem
8221 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
8222 long time.)
8223
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008224- Issue #1580: On most platforms, use a 'short' float repr: for a
8225 finite float x, repr(x) now outputs a string based on the shortest
8226 sequence of decimal digits that rounds to x. Previous behaviour was
8227 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00008228 Another minor difference is that the new repr switches to
8229 exponential notation at 1e16 instead of the previous 1e17; this
8230 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008231
8232 There's a new sys attribute sys.float_repr_style, which takes
8233 the value 'short' to indicate that we're using short float repr,
8234 and 'legacy' if the short float repr isn't available for one
8235 reason or another.
8236
8237 The float repr change involves incorporating David Gay's 'perfect
8238 rounding' code into the Python core (it's in Python/dtoa.c). As a
8239 secondary consequence, all string-to-float and float-to-string
8240 conversions (including all float formatting operations) will be
8241 correctly rounded on these platforms.
8242
Georg Brandl5f90d792010-08-01 22:31:05 +00008243 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008244 this change does not apply.
8245
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00008246- Issue #5759: float() didn't call __float__ on str subclasses.
8247
Georg Brandlabc38772009-04-12 15:51:51 +00008248- The string.maketrans() function is deprecated; there is a new static method
8249 maketrans() on the bytes and bytearray classes. This removes confusion about
8250 the types string.maketrans() is supposed to work with, and mirrors the
8251 methods available on the str class.
8252
R. David Murraydc6da8a2009-04-09 22:16:43 +00008253- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

8418
Antoine Pitrou3a652b12009-03-23 18:52:06 +00008419- Issue #4688: Add a heuristic so that tuples and dicts containing only
8420 untrackable objects are not tracked by the garbage collector. This can
8421 reduce the size of collections and therefore the garbage collection overhead
8422 on long-running programs, depending on their particular use of datatypes.

8491
Lars Gustäbel42e00912009-03-22 20:34:29 +00008492- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
8493 forever on incomplete input. That caused tarfile.open() to hang when used
8494 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Mark Dickinsonb40b9472009-03-29 16:58:21 +00008516 struct.error instead of returning b'\xff\xff\xff\xff'. The
8517 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
8518 have been removed from the struct module.

8532
Eric Smith5e5c0db2009-02-20 14:25:03 +00008533- Issue #5247: Improve error message when unknown format codes are
8534 used when using str.format() with str, int, and float arguments.
8535
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00008536- Issue #5249: time.strftime returned malformed string when format string
8537 contained non ascii character on windows.
8538
Benjamin Petersonf5b52242009-03-02 23:31:26 +00008539- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
8540 source has already been decoded into str.
8541
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00008542- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
8543 rotating the object pointer by 4 bits to the right.
8544
Mark Dickinson87ec0852009-02-09 17:15:59 +00008545- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
8546 it now forces its argument to double before testing for infinity.
8547
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00008548- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
8549 returns a non-number type.
8550
Benjamin Peterson87618552009-02-08 15:00:52 +00008551- Issue #5182: Removed memoryview.__str__.
8552
Mark Dickinsonc008a172009-02-01 13:59:22 +00008553- Issue #1717: Removed builtin cmp() function, dropped tp_compare
8554 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00008555 the type definition cmpfunc. The tp_compare slot has been renamed
8556 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00008557
Georg Brandl1cdd83c2009-04-05 20:24:29 +00008558- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00008559 were suppressing all exceptions. These include list() and bytearray().
8560
Mark Dickinson1124e712009-01-28 21:25:58 +00008561- Issue #4707: round(x, n) now returns an integer if x is an integer.
8562 Previously it returned a float.
8563
Antoine Pitroub52ec782009-01-25 16:34:23 +00008564- Issue #4753: By enabling a configure option named '--with-computed-gotos'
8565 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
8566 evaluation loop is compiled with a new dispatch mechanism which gives
8567 speedups of up to 20%, depending on the system, on various benchmarks.
8568
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00008569- Issue #4874: Most builtin decoders now reject unicode input.

8575
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00008576- Issue #4838: When a module is deallocated, free the memory backing the
8577 optional module state data.
8578
Mark Dickinson8055afd2009-01-17 10:04:45 +00008579- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008580 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00008581
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00008582- Issue #4935: The overflow checking code in the expandtabs() method common
8583 to str, bytes and bytearray could be optimized away by the compiler, letting
8584 the interpreter segfault instead of raising an error.
8585
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00008586- Issue #3720: Fix a crash when an iterator modifies its class and removes its
8587 __next__ method.
8588
Mark Dickinsone5e298f2009-01-12 20:49:19 +00008589- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
8590 function no longer attempt to call the __long__ slot to convert an object
8591 to an integer. Only the __int__ and __trunc__ slots are examined.
8592
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00008593- Issue #4893: Use NT threading on CE.
8594
Martin v. Löwisec59d042009-01-12 07:59:10 +00008595- Issue #4915: Port sysmodule to Windows CE.
8596
Antoine Pitrouab868312009-01-10 15:40:25 +00008597- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
8598 common cases are optimized thanks to a dedicated fast path and a moderate
8599 amount of loop unrolling.
8600
Antoine Pitrou14b78f52009-01-09 22:27:08 +00008601- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
8602 collecting the oldest generation) so that allocating lots of objects without
8603 destroying them does not show quadratic performance. Based on a proposal by
8604 Martin von Löwis at
8605 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
8606
Vinay Sajip6268cbc2009-01-21 00:19:28 +00008607- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00008608 having been closed (for instance, a read() call could return some
8609 previously buffered data). Patch by Dmitry Vasiliev.
8610
Antoine Pitrou05608432009-01-09 18:53:14 +00008611- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
8612 flag to work properly. Furthermore, when specifying -u, the text stdout
8613 and stderr streams have line-by-line buffering enabled (the default being
8614 to buffer arbitrary chunks of data).
8615
Raymond Hettinger35631532009-01-09 03:58:09 +00008616- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
8617 instead of ints (reducing its size from 4 to 8 times thereby reducing
8618 Python's overall memory).
8619
Antoine Pitroud35cbf62009-01-06 19:02:24 +00008620- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
8621 an existing .py counterpart, override the co_filename attributes of all
8622 code objects if the original filename is obsolete (which can happen if the
8623 file has been renamed, moved, or if it is accessed through different paths).
8624 Patch by Ziga Seilnacht and Jean-Paul Calderone.
8625
Antoine Pitrouc3b39242009-01-03 16:59:18 +00008626- Issue #4580: Fix slicing of memoryviews when the item size is greater than
8627 one byte. Also fixes the meaning of len() so that it returns the number of
8628 items, rather than the size in bytes.
8629
Martin v. Löwis5c88d812009-01-02 20:47:48 +00008630- Issue #4075: Use OutputDebugStringW in Py_FatalError.
8631
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00008632- Issue #4747: When the terminal does not use utf-8, executing a script with
8633 non-ascii characters in its name could fail with a "SyntaxError: None" error.
8634
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008635- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
8636 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00008637
Antoine Pitrou7ddda782009-01-01 15:35:33 +00008638- Issue #3680: Reference cycles created through a dict, set or deque iterator
8639 did not get collected.
8640
Nick Coghlanf1f2f682008-12-30 07:29:12 +00008641- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
8642 where the tp_hash and tp_dict slots are both NULL.
8643
Georg Brandlccc47b62008-12-28 11:44:14 +00008644- Issue #4759: None is now allowed as the first argument of
8645 bytearray.translate(). It was always allowed for bytes.translate().
8646
Skip Montanaro80072cb2008-12-23 03:51:14 +00008647- Added test case to ensure attempts to read from a file opened for writing
8648 fail.
8649
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00008650- Issue #3106: Speedup some comparisons (str/str and int/int).

8654
Antoine Pitrou621601a2008-12-17 23:18:19 +00008655- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
8656 print elapsed times, not only when some objects are uncollectable /
8657 unreachable. Original patch by Neil Schemenauer.
8658
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00008659- Issue #3439: Add a bit_length method to int.
8660
Mark Dickinsonda2706b2008-12-11 18:03:03 +00008661- Issue #2173: When getting device encoding, check that return value of
8662 nl_langinfo is not the empty string. This was causing silent build
8663 failures on OS X.
8664
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00008665- Issue #4597: Fixed several opcodes that weren't always propagating
8666 exceptions.
8667
8668- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00008669 context manager returns a value that cannot be converted to a bool.
8670
Mark Dickinsonfd24b322008-12-06 15:33:31 +00008671- Issue #4445: Replace "sizeof(PyBytesObject)" with
8672 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
8673 bytes instances. On a typical machine this saves 3 bytes of memory
8674 (on average) per allocation of a bytes instance.
8675
Christian Heimesa872de52008-12-05 08:26:55 +00008676- Issue #4533: File read operation was dreadfully slow due to a slowly
8677 growing read buffer. Fixed by using the same growth rate algorithm as
8678 Python 2.x.
8679
Antoine Pitrou5504e892008-12-06 21:27:53 +00008680- Issue #4509: Various issues surrounding resize of bytearray objects to
8681 which there are buffer exports (e.g. memoryview instances).
8682
Georg Brandlf9734072008-12-07 15:30:06 +00008683- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
8684 method on file objects with closefd=False. The file descriptor is still
8685 kept open but the file object behaves like a closed file. The ``FileIO``
8686 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00008687
Antoine Pitroubc420402008-12-07 20:14:49 +00008688- Issue #4569: Interpreter crash when mutating a memoryview with an item size
8689 larger than 1.

8694
Walter Dörwaldc1651a02009-05-03 22:55:55 +00008695- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
8696 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
8697 step. This avoids problems with counting UTF-8 bytes that ignores the effect
8698 of using the replace error handler in PyUnicode_DecodeUTF8().
