Ned Deily657b2de2011-06-28 19:51:30 -0700296- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
297 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
298 interpreter process. This could cause failures in non-Distutils subprocesses
299 and was unreliable since tests or user programs could modify the interpreter
300 environment after Distutils set it. Instead, have Distutils set the the
301 deployment target only in the environment of each build subprocess. It is
302 still possible to globally override the default by setting
303 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
304 greater or equal to the default value, the value with which the interpreter

Victor Stinnerf933e1a2010-10-20 22:58:25 +00001802 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001803 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

1918 your app validates with Python <3.2b1+, but not on this version, it is likely
1919 the case that your app was not compliant.)

Georg Brandl27a28582010-10-10 09:49:21 +00002187- All SyntaxErrors now have a column offset and therefore a caret when the error

Georg Brandl27a28582010-10-10 09:49:21 +00002196- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2197 with a non-empty format string. This is an effort to future-proof user
2198 code. If a derived class does not currently implement __format__ but later
2199 adds its own __format__, it would most likely break user code that had
2200 supplied a format string. This will be changed to a DeprecationWaring in
2201 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002203- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

2205 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 +00002207- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2208 functions from the libc caused the methods .upper() and lower() to become

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002214- Issue #4617: Previously it was illegal to delete a name from the local
2215 namespace if it occurs as a free variable in a nested block. This limitation
2216 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2217
Georg Brandl27a28582010-10-10 09:49:21 +00002218- Issue #9804: ascii() now always represents unicode surrogate pairs as a single

2220 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2221 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002256- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002257 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002258 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002259 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002399- Issue #9792: In case of connection failure, socket.create_connection() would
2400 swallow the exception and raise a new one, making it impossible to fetch the
2401 original errno, or to filter timeout errors. Now the original error is
2402 re-raised.

2405 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2406 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002408- Updates to the random module:
2409
Georg Brandl27a28582010-10-10 09:49:21 +00002410 * Document which parts of the module are guaranteed to stay the same across
2411 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002412
Georg Brandl27a28582010-10-10 09:49:21 +00002413 * Update the seed() method to use all of the bits in a string instead of just
2414 the hash value. This makes better use of the seed value and assures the
2415 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002416
Georg Brandl27a28582010-10-10 09:49:21 +00002417 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2418 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2419 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002420
2421 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002440- hashlib has two new constant attributes: algorithms_guaranteed and
2441 algorithms_avaiable that respectively list the names of hash algorithms
2442 guaranteed to exist in all Python implementations and the names of hash
2443 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00002548- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2549 now removed, since their effect was inexistent in 3.x (the default encoding is
2550 hardcoded to utf-8 and cannot be changed).

2572 return characters from the full Unicode range, even on narrow unicode builds
2573 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2574 in Python is that unicodedata.numeric() now returns the correct value for
2575 large code points, and repr() may consider more characters as printable.
2576
Victor Stinner6c00c142010-08-17 23:37:11 +00002577- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00002594 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2595 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00002612- Issue #9416: Fix some issues with complex formatting where the output with no
2613 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002614
2615 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2616 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Ezio Melotti57221d02010-07-01 07:32:02 +00002955- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002956 start byte and the continuation byte(s) are now considered invalid, instead of
2957 the number of bytes specified by the start byte. E.g.:
2958 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2959 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2960 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2961 returned a single u'\ufffd'.

2976 dealing with unary minus applied to a constant. The removed code was mutating
2977 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00002981 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002982 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002983
Victor Stinner25e8ec42010-06-25 00:02:38 +00002984- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use

2990
Georg Brandl62069d32010-07-31 08:56:11 +00002991- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002992 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2993 location of the raised exception.
2994
Victor Stinner313a1202010-06-11 23:56:51 +00002995- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2996 filenames and enable os.fsencode().
2997
Benjamin Peterson285a6892010-06-22 19:21:52 +00002998- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2999
Georg Brandl62069d32010-07-31 08:56:11 +00003000- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the

Georg Brandl62069d32010-07-31 08:56:11 +00003004- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3005 TypeError instead of giving a DeprecationWarning when a float is parsed using
3006 the 'L' code (for long long). (All other integer codes already raise
3007 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003008
Victor Stinner600d3be2010-06-10 12:00:55 +00003009- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3010 enable shortcuts for upper case encoding name. Add also a shortcut for
3011 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3012
Georg Brandl62069d32010-07-31 08:56:11 +00003013- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3014 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003015
3016- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003017 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003018 like bytearray.
3019
Georg Brandl62069d32010-07-31 08:56:11 +00003020- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003021 used anymore and it was never documented.
3022
Georg Brandl62069d32010-07-31 08:56:11 +00003023- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +00003025- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3026 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003027
Georg Brandl62069d32010-07-31 08:56:11 +00003028- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3029 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3030 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3031 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003032
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003033- Issue #8748: Fix two issues with comparisons between complex and integer
3034 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003035 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3036 (2) The comparison raised an OverflowError for large integers, leading to
3037 unpredictable exceptions when combining integers and complex objects in sets
3038 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003039
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003040- Issue #8766: Initialize _warnings module before importing the first module.

3042
Victor Stinner9ca9c252010-05-19 16:53:30 +00003043- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003044 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003045 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003046
Georg Brandl62069d32010-07-31 08:56:11 +00003047- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3048 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003049
Victor Stinnerae6265f2010-05-15 16:27:27 +00003050- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3051 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003052 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003053 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003054
Victor Stinner59e62db2010-05-15 13:14:32 +00003055- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003056 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003057
Victor Stinnerb744ba12010-05-15 12:27:16 +00003058- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003059 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003060 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3061
Victor Stinner0964ee12010-04-30 16:48:45 +00003062- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003063 PyUnicode_FromString() to support surrogates in the filename and use the right
3064 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003065
Georg Brandl8569e582010-05-19 20:57:08 +00003066- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3067
Georg Brandl62069d32010-07-31 08:56:11 +00003068- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003069
Benjamin Petersonfb886362010-04-24 18:21:17 +00003070- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3071 arguments.
3072
Victor Stinner14284c22010-04-23 12:02:30 +00003073- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003074 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Mark Dickinsonf673f0c2010-03-13 09:48:39 +00003117- Issue #7845: Rich comparison methods on the complex type now return
3118 NotImplemented rather than raising a TypeError when comparing with an
3119 incompatible type; this allows user-defined classes to implement their own

Antoine Pitroufc8d6f42010-01-17 12:38:54 +00003166
Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003167- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003168 where the right hand operand is a set of constants, by turning the set into a
3169 frozenset and pre-building it as a constant. The comparison operation is made
3170 against the constant instead of building a new set each time it is executed (a
3171 similar optimization already existed which turned a list of constants into a
3172 pre-built tuple). Patch and additional tests by Dave Malcolm.

3179 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3180 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3181 parsing certain long numeric strings corresponding to subnormal values, (3) a
3182 memory leak for some values large enough to cause overflow, and (4) a number
3183 of flaws that could lead to incorrectly rounded results.

Georg Brandl62069d32010-07-31 08:56:11 +00003197- Issue #1811: improve accuracy and cross-platform consistency for true division
3198 of integers: the result of a/b is now correctly rounded for ints a and b (at
3199 least on IEEE 754 platforms), and in particular does not depend on the
3200 internal representation of an int.
Mark Dickinsoncbb62742009-12-27 15:09:50 +00003201
Ronald Oussoren6f6c5622009-12-24 14:03:19 +00003202- Issue #6834: replace the implementation for the 'python' and 'pythonw'

3204
Georg Brandl62069d32010-07-31 08:56:11 +00003205 These executables now work properly with the arch(1) command: ``arch -ppc

3225
Georg Brandl62069d32010-07-31 08:56:11 +00003226- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
3227 range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
3228 long but the length of the range did not. Also fix several cases where
3229 reversed(range(a, b, c)) gave wrong results, and fix a refleak for
3230 reversed(range(a, b, c)) with large arguments.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003340- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
3341 variable argument list. `Py_VA_COPY` is equivalent to C99
3342 `va_copy`, but available on all python platforms.
3343
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003344- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3345 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3346 "step = -step" when reversing a slice.
3347
Georg Brandl62069d32010-07-31 08:56:11 +00003348- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the
3349 interpreter to set sys.argv without also modifying sys.path. This helps fix
3350 `CVE-2008-5983
Antoine Pitrouf978fac2010-05-21 17:25:34 +00003351 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

Benjamin Petersonfb886362010-04-24 18:21:17 +00003353- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
3354 strings in an efficient manner.
3355
Antoine Pitrou8689a102010-04-01 16:53:15 +00003356- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003357 function declaration, which was kept for backwards compatibility reasons, is
3358 now removed (the macro was introduced in 1997!).
Antoine Pitrou8689a102010-04-01 16:53:15 +00003359
Georg Brandl62069d32010-07-31 08:56:11 +00003360- Issue #7767: New function PyLong_AsLongLongAndOverflow added, analogous to

Georg Brandl62069d32010-07-31 08:56:11 +00003367 PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
3368 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3369 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003370 to match the behaviour of the other integer format codes.
3371
Georg Brandl62069d32010-07-31 08:56:11 +00003372- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.

Georg Brandl62069d32010-07-31 08:56:11 +00003380- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3381 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3382 accessing the d_type and d_name members of structures using PyDescr_COMMON.
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +00003383

3395 ``const char *`` as the string is stored beyond the call.
3396
Georg Brandl62069d32010-07-31 08:56:11 +00003397- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3398 allocator will be automatically disabled when running under Valgrind. This
3399 gives improved memory leak detection when running under Valgrind, while taking
3400 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003473- The default size of the re module's compiled regular expression cache has been
3474 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003475 simply clearing the entire cache on overflow to forgetting the least recently
3476 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003477 applications that use a lot of regular expressions and limits the impact of
3478 the performance hit anytime the cache is exceeded.

3491 module is renamed to `_datetime` and if available, overrides all classes
3492 defined in datetime with fast C impementation. Python implementation is based
3493 on the original python prototype for the datetime module by Tim Peters with
3494 minor modifications by the PyPy project. The test suite now tests `datetime`
3495 module with and without `_datetime` acceleration using the same test cases.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003851 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003852 relies on the system threading library, so as to avoid a semi-busy wait loop.

Georg Brandl62069d32010-07-31 08:56:11 +00003887- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3888 InvalidOperation instead of returning False. (Comparisons involving a quiet
3889 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3890 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00003892- Issue #2531: Comparison operations between floats and Decimal instances now
3893 return a result based on the numeric values of the operands; previously they
3894 returned an arbitrary result based on the relative ordering of id(float) and
3895 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3896 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003897
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003898- Added a subtract() method to collections.Counter().
3899
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003900- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003901 argument `-` which tells it to read files to compile from stdin. Each line is
3902 read on demand and the named file is compiled immediately. (Original patch by
3903 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00003905- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00003909- Comparisons using one of <, <=, >, >= between a complex instance and a
3910 Fractions instance now raise TypeError instead of returning True/False. This
3911 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3912 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003955- The internals of the subprocess module on POSIX systems have been replaced by
3956 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3957 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00003959- subprocess.Popen now has restore_signals and start_new_session features. The
3960 default of restore_signals=True is a new behavior compared to earlier Python
3961 versions. This means that signals such as SIGPIPE are not ignored by default
3962 in subprocesses launched by Python (Issue #1652).

4049 position when calling `truncate()`. It would previously change the file
4050 position to the given argument, which goes against the tradition of

4055 archive. The new implementation is significantly faster and can be wrapped in
4056 a :class:`io.BufferedReader` object for more speedups. It also solves an
4057 issue where interleaved calls to `read()` and `readline()` give wrong results.

Georg Brandl62069d32010-07-31 08:56:11 +00004260- Issue #7246 & Issue #7208: getpass now properly flushes input before reading
4261 from stdin so that existing input does not confuse it and lead to incorrect
4262 entry or an IOError. It also properly flushes it afterwards to avoid the
4263 terminal echoing the input afterwards on OSes such as Solaris.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004455- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004456 compared to other unix systems. In particular, os.getgroups() does not reflect

5052 library. This means, for example, that opening an UTF-16 text file in
5053 append mode doesn't add a BOM at the end of the file if the file isn't
5054 empty.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005103
5104Core and Builtins
5105-----------------
5106
Mark Dickinson865e01a2009-05-07 16:37:01 +00005107- Issue #5914: Add new C API function PyOS_string_to_double, and
5108 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5109
Eric Smith741191f2009-05-06 13:08:15 +00005110- Issue #3382: float.__format__, complex.__format__, and %-formatting
5111 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5112 affects nan -> NAN and inf -> INF.
5113
Mark Hammond5a607a32009-05-06 08:04:54 +00005114- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5115 in all operations, including splitdrive, split, etc. splitunc() now issues
5116 a PendingDeprecation warning.
5117
Eric Smith63376222009-05-05 14:04:18 +00005118- Issue #5920: For float.__format__, change the behavior with the
5119 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5120 to be like 'g' but with at least one decimal point and with a
5121 default precision of 12. Previously, the behavior the same but with
5122 a default precision of 6. This more closely matches str(), and
5123 reduces surprises when adding alignment flags to the empty
5124 presentation type. This also affects the new complex.__format__ in
5125 the same way.
5126
Martin v. Löwis011e8422009-05-05 04:43:17 +00005127- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5128
R. David Murrayb18500d2009-05-04 22:59:07 +00005129- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5130 shadowed by classtype's, even if it was None. property now
5131 inserts the __doc__ into the subclass instance __dict__.
5132
Antoine Pitrou244651a2009-05-04 18:56:13 +00005133- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5134 sequences. Patch by Nick Barnes and Victor Stinner.
5135
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005136- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005137
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005138- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5139 received a new method, detach(). detach() disconnects the underlying stream
5140 from the buffer or text IO and returns it.
5141
Mark Dickinson33841c32009-05-01 15:37:04 +00005142- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5143 floats with absolute value over 1e50. Also remove length
5144 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5145 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005146
Eric Smith741191f2009-05-06 13:08:15 +00005147- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005148 format(complex(1, 2./3), '.5') now produces a sensible result.
5149
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005150- Issue #5864: Fix empty format code formatting for floats so that it
5151 never gives more than the requested number of significant digits.
5152
Eric Smith6dc46f52009-04-27 20:39:49 +00005153- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5154 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5155
Eric Smithcc32a112009-04-26 21:35:14 +00005156- Issue #5835: Deprecate PyOS_ascii_formatd.
5157
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005158- Issue #4971: Fix titlecase for characters that are their own
5159 titlecase, but not their own uppercase.
5160
Benjamin Peterson193152c2009-04-25 01:08:45 +00005161- Issue #5283: Setting __class__ in __del__ caused a segfault.
5162
Mark Dickinsonad476da2009-04-23 19:14:16 +00005163- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5164 z involves nans, infs or negative zeros.
5165
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005166- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005167
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005168- Issue #1869 (and many duplicates): make round(x, n) correctly
5169 rounded for a float x, by using the decimal <-> binary conversions
5170 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5171 consistently agrees with format(x, '.2f').
5172
Benjamin Petersonae937c02009-04-18 20:54:08 +00005173- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5174 some builtin types.
5175
Eric Smith0923d1d2009-04-16 20:16:10 +00005176- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5177
Eric Smith35e84722009-04-16 20:21:28 +00005178- Issue #5515: str.format() type 'n' combined with commas and leading
5179 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005180
5181- Implement PEP 378, Format Specifier for Thousands Separator, for
5182 floats.
5183
Mark Dickinson3370cce2009-04-17 22:40:53 +00005184- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005185 1e11, not 1e12. This avoids printing 13 significant digits in
5186 situations where only 12 of them are correct. Example problem
5187 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5188 long time.)
5189
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005190- Issue #1580: On most platforms, use a 'short' float repr: for a
5191 finite float x, repr(x) now outputs a string based on the shortest
5192 sequence of decimal digits that rounds to x. Previous behaviour was
5193 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005194 Another minor difference is that the new repr switches to
5195 exponential notation at 1e16 instead of the previous 1e17; this
5196 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005197
5198 There's a new sys attribute sys.float_repr_style, which takes
5199 the value 'short' to indicate that we're using short float repr,
5200 and 'legacy' if the short float repr isn't available for one
5201 reason or another.
5202
5203 The float repr change involves incorporating David Gay's 'perfect
5204 rounding' code into the Python core (it's in Python/dtoa.c). As a
5205 secondary consequence, all string-to-float and float-to-string
5206 conversions (including all float formatting operations) will be
5207 correctly rounded on these platforms.
5208
Georg Brandl5f90d792010-08-01 22:31:05 +00005209 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005210 this change does not apply.
5211
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005212- Issue #5759: float() didn't call __float__ on str subclasses.
5213
Georg Brandlabc38772009-04-12 15:51:51 +00005214- The string.maketrans() function is deprecated; there is a new static method
5215 maketrans() on the bytes and bytearray classes. This removes confusion about
5216 the types string.maketrans() is supposed to work with, and mirrors the
5217 methods available on the str class.
5218
R. David Murraydc6da8a2009-04-09 22:16:43 +00005219- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5220 its clarity and its speed.
5221
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005222- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005223 to avoid compiler warnings.
5224
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005225- Issue #3739: The unicode-internal encoder now reports the number of characters
5226 consumed like any other encoder (instead of the number of bytes).

5386 untrackable objects are not tracked by the garbage collector. This can
5387 reduce the size of collections and therefore the garbage collection overhead

5579 and stderr streams have line-by-line buffering enabled (the default being
5580 to buffer arbitrary chunks of data).
5581
Raymond Hettinger35631532009-01-09 03:58:09 +00005582- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5583 instead of ints (reducing its size from 4 to 8 times thereby reducing
5584 Python's overall memory).
5585
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005586- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5587 an existing .py counterpart, override the co_filename attributes of all
5588 code objects if the original filename is obsolete (which can happen if the
5589 file has been renamed, moved, or if it is accessed through different paths).
5590 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5591
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005592- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5593 one byte. Also fixes the meaning of len() so that it returns the number of
5594 items, rather than the size in bytes.
5595

Georg Brandlccc47b62008-12-28 11:44:14 +00005610- Issue #4759: None is now allowed as the first argument of

5612

5638 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

5644 Python 2.x.
5645
Antoine Pitrou5504e892008-12-06 21:27:53 +00005646- Issue #4509: Various issues surrounding resize of bytearray objects to

5648
Georg Brandlf9734072008-12-07 15:30:06 +00005649- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5650 method on file objects with closefd=False. The file descriptor is still
5651 kept open but the file object behaves like a closed file. The ``FileIO``
5652 object also got a new readonly attribute ``closefd``.

5662 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5663 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5664 of using the replace error handler in PyUnicode_DecodeUTF8().

5983
Antoine Pitrou08838b62009-01-21 00:55:13 +00005984- Issue #5008: When a file is opened in append mode with the new IO library,
5985 do an explicit seek to the end of file (so that e.g. tell() returns the

6017 appropriately when it is being used via socket.makefile() objects
6018 rather than delaying the close by waiting for garbage collection to do it.
