11-----------------
12
Antoine Pitrou093ce9c2011-12-16 11:24:27 +010013- Issue #6695: Full garbage collection runs now clear the freelist of set
14 objects. Initial patch by Matthias Troffaes.
15
Antoine Pitroue0e27352011-12-15 14:31:28 +010016- Fix OSError.__init__ and OSError.__new__ so that each of them can be
17 overriden and take additional arguments (followup to issue #12555).
18
Antoine Pitrou2e872082011-12-15 14:15:31 +010019- Fix the fix for issue #12149: it was incorrect, although it had the side
20 effect of appearing to resolve the issue. Thanks to Mark Shannon for
21 noticing.
22
Alexandre Vassalotti3bfc65a2011-12-13 13:08:09 -050023- Issue #13505: Pickle bytes objects in a way that is compatible with
24 Python 2 when using protocols <= 2.

Barry Warsaw9f571352011-12-05 16:45:02 -050026- Issue #11147: Fix an unused argument in _Py_ANNOTATE_MEMORY_ORDER. (Fix
27 given by Campbell Barton).
28

30 pickle protocol >= 3. The old reduction format is kept with older protocols
31 in order to allow unpickling under Python 2. Patch by Irmen de Jong.
32
Antoine Pitrou11942a52011-11-28 19:08:36 +010033- Issue #7111: Python can now be run without a stdin, stdout or stderr
34 stream. It was already the case with Python 2. However, the corresponding
35 sys module entries are now set to None (instead of an unusable file object).
36
Antoine Pitrouf0effe62011-11-26 01:11:02 +010037- Issue #11849: Ensure that free()d memory arenas are really released
38 on POSIX systems supporting anonymous memory mappings. Patch by
39 Charles-François Natali.
40
Victor Stinnercad939b2011-11-25 20:11:54 +010041- Issue #13452: PyUnicode_EncodeDecimal() doesn't support error handlers
Victor Stinner6345be92011-11-25 20:09:01 +010042 different than "strict" anymore. The caller was unable to compute the
43 size of the output buffer: it depends on the error handler.
44
Antoine Pitrou86a36b52011-11-25 18:56:07 +010045- PEP 3155 / issue #13448: Qualified name for classes and functions.

54 to allow compiling extension modules with -Wswitch-enum on gcc.
55 Initial patch by Floris Bruynooghe.
56
Antoine Pitrouf34a0cd2011-11-18 20:14:34 +010057- Issue #10227: Add an allocation cache for a single slice object. Patch by
58 Stefan Behnel.
59
Antoine Pitrou56a220a2011-11-16 00:56:10 +010060- Issue #13393: BufferedReader.read1() now asks the full requested size to
61 the raw stream instead of limiting itself to the buffer size.
62
Antoine Pitrou28e401e2011-11-15 19:15:19 +010063- Issue #13392: Writing a pyc file should now be atomic under Windows as well.
64
Antoine Pitrou5418ee02011-11-15 01:42:21 +010065- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
66 already accepts them).
67
Antoine Pitrou9a812cb2011-11-15 00:00:12 +010068- Issue #13389: Full garbage collection passes now clear the freelists for
69 list and dict objects. They already cleared other freelists in the
70 interpreter.
71
Brian Curtin52fbea12011-11-06 13:41:17 -060072- Issue #13327: Remove the need for an explicit None as the second argument
Brian Curtin304a1652011-11-07 16:30:01 -060073 to os.utime, os.lutimes, os.futimes, os.futimens, os.futimesat, in
74 order to update to the current time. Also added keyword argument
75 handling to os.utimensat in order to remove the need for explicit None.
Brian Curtin52fbea12011-11-06 13:41:17 -060076
Amaury Forgeot d'Arc864741b2011-11-06 15:10:48 +010077- Issue #13350: Simplify some C code by replacing most usages of
78 PyUnicode_Format by PyUnicode_FromFormat.

102 object identity).
103
Nick Coghlande31b192011-10-23 22:04:16 +1000104- Issue #1294232: In a few cases involving metaclass inheritance, the

952
Ned Deily657b2de2011-06-28 19:51:30 -0700953- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
954 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
955 interpreter process. This could cause failures in non-Distutils subprocesses
956 and was unreliable since tests or user programs could modify the interpreter
957 environment after Distutils set it. Instead, have Distutils set the the
958 deployment target only in the environment of each build subprocess. It is
959 still possible to globally override the default by setting
960 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
961 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700962 was built. Also, implement the same handling in packaging.

Georg Brandl255abdd2011-01-16 14:17:26 +00002207 continuation line in the formatted value has no leading white space and looks
2208 like a header. Since Generator uses Header to format all headers, this check
2209 is made for all headers in any serialized message at serialization time. This
2210 provides protection against header injection attacks.

R. David Murray92532142011-01-07 23:25:30 +00002221
Éric Araujof0ab5d62011-05-29 03:43:59 +02002222- email.header.Header was incorrectly encoding folding whitespace when

2224 folding whitespace. It now uses the continuation_ws, as it does for
2225 continuation lines that it creates itself.

2228 time.asctime(), time.ctime() and time.strftime() functions will now format

2230 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
2231 supported by the OS. With Visual Studio or on Solaris, the year is limited to
2232 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002865 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002866 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002867 encoding and to encode command line arguments on this OS.

2870 filenames encoded to the filesystem encoding with the surrogateescape error

Benjamin Peterson230b2062010-10-16 03:45:45 +00002873- Issue #9997: Don't let the name "top" have special significance in scope

Georg Brandl27a28582010-10-10 09:49:21 +00003219- ast.literal_eval() can now handle negative numbers. It is also a little more
3220 liberal in what it accepts without compromising the safety of the evaluation.
3221 For example, 3j+4 and 3+4+5 are both accepted.

Georg Brandl27a28582010-10-10 09:49:21 +00003252- All SyntaxErrors now have a column offset and therefore a caret when the error

Georg Brandl27a28582010-10-10 09:49:21 +00003261- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3262 with a non-empty format string. This is an effort to future-proof user
3263 code. If a derived class does not currently implement __format__ but later
3264 adds its own __format__, it would most likely break user code that had
3265 supplied a format string. This will be changed to a DeprecationWaring in
3266 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00003268- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3269 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3270 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 +00003272- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3273 functions from the libc caused the methods .upper() and lower() to become
3274 locale aware and created subtly wrong results.
3275
Georg Brandl27a28582010-10-10 09:49:21 +00003276- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003279- Issue #4617: Previously it was illegal to delete a name from the local
3280 namespace if it occurs as a free variable in a nested block. This limitation
3281 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3282
Georg Brandl27a28582010-10-10 09:49:21 +00003283- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3284 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3285 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3286 single character on UCS-2 builds.

Antoine Pitrou079ce542010-09-08 12:37:10 +00003292- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00003321- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003322 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003323 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003324 replacement for old handle_accept() and avoids the user to call accept()

3457 friendlier towards reference cycles. This change is not normally visible
3458 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003460- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3461 still return the id of the parent process after it has exited. This process
3462 id may even have been reused by another unrelated process.
3463
Georg Brandl27a28582010-10-10 09:49:21 +00003464- Issue #9792: In case of connection failure, socket.create_connection() would
3465 swallow the exception and raise a new one, making it impossible to fetch the
3466 original errno, or to filter timeout errors. Now the original error is
3467 re-raised.

3470 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3471 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003473- Updates to the random module:
3474
Georg Brandl27a28582010-10-10 09:49:21 +00003475 * Document which parts of the module are guaranteed to stay the same across
3476 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00003478 * Update the seed() method to use all of the bits in a string instead of just
3479 the hash value. This makes better use of the seed value and assures the
3480 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003481
Georg Brandl27a28582010-10-10 09:49:21 +00003482 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3483 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3484 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003485
3486 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003505- hashlib has two new constant attributes: algorithms_guaranteed and

3507 guaranteed to exist in all Python implementations and the names of hash
3508 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00003613- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3614 now removed, since their effect was inexistent in 3.x (the default encoding is

3637 return characters from the full Unicode range, even on narrow unicode builds
3638 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3639 in Python is that unicodedata.numeric() now returns the correct value for
3640 large code points, and repr() may consider more characters as printable.
3641
Victor Stinner6c00c142010-08-17 23:37:11 +00003642- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00003677- Issue #9416: Fix some issues with complex formatting where the output with no
3678 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003679
3680 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00004020- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00004021 start byte and the continuation byte(s) are now considered invalid, instead of
4022 the number of bytes specified by the start byte. E.g.:
4023 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
4024 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
4025 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
4026 returned a single u'\ufffd'.

4041 dealing with unary minus applied to a constant. The removed code was mutating
4042 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00004046 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00004047 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00004048
Victor Stinner25e8ec42010-06-25 00:02:38 +00004049- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
4050 "w*" format instead. Add tests for "w*" format.
4051
Victor Stinner06e49dd2010-06-13 18:21:50 +00004052- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00004053 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00004054 string formats.
4055
Georg Brandl62069d32010-07-31 08:56:11 +00004056- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00004057 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
4058 location of the raised exception.
4059
Victor Stinner313a1202010-06-11 23:56:51 +00004060- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
4061 filenames and enable os.fsencode().
4062
Benjamin Peterson285a6892010-06-22 19:21:52 +00004063- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
4064
Georg Brandl62069d32010-07-31 08:56:11 +00004065- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
4066 interpreter with characters outside the Basic Multilingual Plane (higher than
4067 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00004068
Georg Brandl62069d32010-07-31 08:56:11 +00004069- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
4070 TypeError instead of giving a DeprecationWarning when a float is parsed using
4071 the 'L' code (for long long). (All other integer codes already raise
4072 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00004073
Victor Stinner600d3be2010-06-10 12:00:55 +00004074- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
4075 enable shortcuts for upper case encoding name. Add also a shortcut for
4076 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
4077
Georg Brandl62069d32010-07-31 08:56:11 +00004078- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
4079 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004080
4081- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00004082 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004083 like bytearray.
4084
Georg Brandl62069d32010-07-31 08:56:11 +00004085- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00004086 used anymore and it was never documented.
4087
Georg Brandl62069d32010-07-31 08:56:11 +00004088- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +00004090- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
4091 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00004092
Georg Brandl62069d32010-07-31 08:56:11 +00004093- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
4094 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
4095 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
4096 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00004097
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004098- Issue #8748: Fix two issues with comparisons between complex and integer
4099 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00004100 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
4101 (2) The comparison raised an OverflowError for large integers, leading to
4102 unpredictable exceptions when combining integers and complex objects in sets
4103 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004104
Victor Stinner7d79b8b2010-05-19 20:40:50 +00004105- Issue #8766: Initialize _warnings module before importing the first module.
4106 Fix a crash if an empty directory called "encodings" exists in sys.path.
4107
Victor Stinner9ca9c252010-05-19 16:53:30 +00004108- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00004109 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00004110 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00004111
Georg Brandl62069d32010-07-31 08:56:11 +00004112- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
4113 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00004114
Victor Stinnerae6265f2010-05-15 16:27:27 +00004115- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
4116 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00004117 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00004118 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00004119
Victor Stinner59e62db2010-05-15 13:14:32 +00004120- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00004121 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00004122
Victor Stinnerb744ba12010-05-15 12:27:16 +00004123- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00004124 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00004125 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
4126
Victor Stinner0964ee12010-04-30 16:48:45 +00004127- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00004128 PyUnicode_FromString() to support surrogates in the filename and use the right
4129 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00004130
Georg Brandl8569e582010-05-19 20:57:08 +00004131- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
4132
Georg Brandl62069d32010-07-31 08:56:11 +00004133- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00004134
Benjamin Petersonfb886362010-04-24 18:21:17 +00004135- Issue #8419: Prevent the dict constructor from accepting non-string keyword
4136 arguments.
4137
Victor Stinner14284c22010-04-23 12:02:30 +00004138- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00004139 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Mark Dickinsond59b4162010-03-13 11:34:40 +00004179- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
Georg Brandl62069d32010-07-31 08:56:11 +00004180 PyMemberDefs could produce an internal error; raise TypeError instead.
Mark Dickinsond59b4162010-03-13 11:34:40 +00004181
Mark Dickinsonf673f0c2010-03-13 09:48:39 +00004182- Issue #7845: Rich comparison methods on the complex type now return
4183 NotImplemented rather than raising a TypeError when comparing with an
4184 incompatible type; this allows user-defined classes to implement their own
4185 comparisons with complex.
4186
Victor Stinner52f6dd72010-03-12 14:45:56 +00004187- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt

4224 add the additional members returned in an OSVERSIONINFOEX structure. The new
4225 members are service_pack_major, service_pack_minor, suite_mask, and
4226 product_type.
Eric Smithf7bb5782010-01-27 00:44:57 +00004227
Georg Brandl62069d32010-07-31 08:56:11 +00004228- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`) could
4229 crash in many places because of the PyByteArray_AS_STRING() macro returning
4230 NULL. The macro now returns a statically allocated empty string instead.
Antoine Pitroufc8d6f42010-01-17 12:38:54 +00004231
Antoine Pitroub7fbcd32010-01-16 18:37:38 +00004232- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00004233 where the right hand operand is a set of constants, by turning the set into a
4234 frozenset and pre-building it as a constant. The comparison operation is made
4235 against the constant instead of building a new set each time it is executed (a
4236 similar optimization already existed which turned a list of constants into a
4237 pre-built tuple). Patch and additional tests by Dave Malcolm.
Antoine Pitroub7fbcd32010-01-16 18:37:38 +00004238
Georg Brandl62069d32010-07-31 08:56:11 +00004239- Issue #7622: Improve the split(), rsplit(), splitlines() and replace() methods
4240 of bytes, bytearray and unicode objects by using a common implementation based
4241 on stringlib's fast search. Patch by Florent Xicluna.
Antoine Pitrouf2c54842010-01-13 08:07:53 +00004242
Georg Brandl62069d32010-07-31 08:56:11 +00004243- Issue #7632: Fix various str -> float conversion bugs present in 2.7 alpha 2,
4244 including: (1) a serious 'wrong output' bug that could occur for long (> 40
4245 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
4246 parsing certain long numeric strings corresponding to subnormal values, (3) a
4247 memory leak for some values large enough to cause overflow, and (4) a number
4248 of flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +00004249
Benjamin Petersonaea44282010-01-04 01:10:28 +00004250- The __complex__ method is now looked up on the class of instances to make it

4257 AttributeError.
4258
Georg Brandl62069d32010-07-31 08:56:11 +00004259- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
4260 in ** operator. The behaviour now conforms to that described in C99 Annex F.

Georg Brandl62069d32010-07-31 08:56:11 +00004262- Issue #1811: improve accuracy and cross-platform consistency for true division
4263 of integers: the result of a/b is now correctly rounded for ints a and b (at
4264 least on IEEE 754 platforms), and in particular does not depend on the
4265 internal representation of an int.
Mark Dickinsoncbb62742009-12-27 15:09:50 +00004266
Ronald Oussoren6f6c5622009-12-24 14:03:19 +00004267- Issue #6834: replace the implementation for the 'python' and 'pythonw'
4268 executables on OSX.
4269
Georg Brandl62069d32010-07-31 08:56:11 +00004270 These executables now work properly with the arch(1) command: ``arch -ppc
4271 python`` will start a universal binary version of python in PPC mode (unlike
4272 previous releases).

4290
Georg Brandl62069d32010-07-31 08:56:11 +00004291- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
4292 range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
4293 long but the length of the range did not. Also fix several cases where
4294 reversed(range(a, b, c)) gave wrong results, and fix a refleak for
4295 reversed(range(a, b, c)) with large arguments.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00004405- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the

Mark Dickinsone6fc7402010-08-06 18:55:26 +00004409- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
4410 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

4464 gives improved memory leak detection when running under Valgrind, while taking
4465 advantage of pymalloc at other times.

4541 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004542 applications that use a lot of regular expressions and limits the impact of
4543 the performance hit anytime the cache is exceeded.

4557 defined in datetime with fast C impementation. Python implementation is based
4558 on the original python prototype for the datetime module by Tim Peters with
4559 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00004952- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4953 InvalidOperation instead of returning False. (Comparisons involving a quiet
4954 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4955 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004957- Issue #2531: Comparison operations between floats and Decimal instances now
4958 return a result based on the numeric values of the operands; previously they
4959 returned an arbitrary result based on the relative ordering of id(float) and
4960 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4961 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004962
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004963- Added a subtract() method to collections.Counter().
4964
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004965- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004966 argument `-` which tells it to read files to compile from stdin. Each line is
4967 read on demand and the named file is compiled immediately. (Original patch by
4968 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004970- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004974- Comparisons using one of <, <=, >, >= between a complex instance and a
4975 Fractions instance now raise TypeError instead of returning True/False. This
4976 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4977 <=> complex, and complex <=> complex comparisons.

Antoine Pitrou910bd512010-03-22 20:11:09 +00004986- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004987 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00005020- The internals of the subprocess module on POSIX systems have been replaced by
5021 an extension module (_posixsubprocess) so that the fork()+exec() can be done
5022 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00005024- subprocess.Popen now has restore_signals and start_new_session features. The
5025 default of restore_signals=True is a new behavior compared to earlier Python
5026 versions. This means that signals such as SIGPIPE are not ignored by default
5027 in subprocesses launched by Python (Issue #1652).

Brett Cannonef7d6722010-02-19 16:04:36 +00005085- Issue #7361: Importlib was not properly checking the number of bytes in
5086 bytecode file when it was less then 8 bytes.
5087
Georg Brandl62069d32010-07-31 08:56:11 +00005088- Issue #7633: In the decimal module, Context class methods (with the exception
5089 of canonical and is_canonical) now accept instances of int and long wherever a
5090 Decimal instance is accepted, and implicitly convert that argument to Decimal.
5091 Previously only some arguments were converted.

Georg Brandl62069d32010-07-31 08:56:11 +00005096- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in XML
5097 processing instructions and comments. These raw characters are allowed by the
5098 XML specification, and are necessary when outputting e.g. PHP code in a
5099 processing instruction. Patch by Neil Muller.

5109 specified, rather than fall through to AF_PACKET (in the `socket` module).
Georg Brandl62069d32010-07-31 08:56:11 +00005110 Also, raise ValueError rather than TypeError when an unknown TIPC address type
5111 is specified. Patch by Brian Curtin.

Georg Brandl62069d32010-07-31 08:56:11 +00005113- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
5114 position when calling `truncate()`. It would previously change the file
5115 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00005116 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5117
Antoine Pitroua32f9a22010-01-27 21:18:57 +00005118- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00005119 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
5120 archive. The new implementation is significantly faster and can be wrapped in
5121 a :class:`io.BufferedReader` object for more speedups. It also solves an
5122 issue where interleaved calls to `read()` and `readline()` give wrong results.
5123 Patch by Nir Aides.

Jesse Noller1f0b6582010-01-27 03:36:01 +00005125- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
Georg Brandl62069d32010-07-31 08:56:11 +00005126 allowing for a maximum number of tasks within the pool to be completed by the
5127 worker before that worker is terminated, and a new one created to replace it.

Benjamin Petersonbf5ff762009-12-13 19:25:34 +00005203- Issue #7349: Make methods of file objects in the io module accept None as an
5204 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
5205 the same as passing no argument.
5206

Tarek Ziadéacafc2d2009-11-29 22:24:57 +00005235- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
5236 ownership when the group is not forced, because the group may be different
5237 from the user's group and inherit from its container when the test is run.
5238

Georg Brandl62069d32010-07-31 08:56:11 +00005282- Issue #6816: runpy now provides a run_path function that allows Python code to
5283 execute file paths that refer to source or compiled Python files as well as
5284 zipfiles, directories and other valid sys.path entries that contain a
5285 __main__.py file. This allows applications that run other Python scripts to
Nick Coghlan260bd3e2009-11-16 06:49:25 +00005286 support the same flexibility as the CPython command line itself.
5287
Georg Brandl62069d32010-07-31 08:56:11 +00005288- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
5289 connection with another process, rather than looping endlessly. The default
5290 timeout is 20 seconds, which should be amply sufficient for local connections.

Antoine Pitrou434736a2009-11-10 18:46:01 +00005303- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00005304 default when instantiating a `threading.RLock` object. This makes recursive
5305 locks as fast as regular non-recursive locks (previously, they were slower by
5306 10x to 15x).

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005561- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005562 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5563 ``datetime.timezone``, return fixed name and UTC offset from their
5564 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5565 returns ``None``. A class attribute, ``utc`` contains an instance
5566 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00005891 runtest_inner in regrtest, with warnings if the called test modifies them, and

6063 (1) inf and nan strings with trailing whitespace were incorrectly
6064 rejected; (2) parsing of strings representing infinities and nans
6065 was locale aware; and (3) the interpretation of fromhex('-nan')
6066 didn't match that of float('-nan').

6169Core and Builtins
6170-----------------
6171
Mark Dickinson865e01a2009-05-07 16:37:01 +00006172- Issue #5914: Add new C API function PyOS_string_to_double, and
6173 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
6174
Eric Smith741191f2009-05-06 13:08:15 +00006175- Issue #3382: float.__format__, complex.__format__, and %-formatting
6176 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
6177 affects nan -> NAN and inf -> INF.
6178
Mark Hammond5a607a32009-05-06 08:04:54 +00006179- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
6180 in all operations, including splitdrive, split, etc. splitunc() now issues
6181 a PendingDeprecation warning.
6182
Eric Smith63376222009-05-05 14:04:18 +00006183- Issue #5920: For float.__format__, change the behavior with the
6184 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6185 to be like 'g' but with at least one decimal point and with a
6186 default precision of 12. Previously, the behavior the same but with
6187 a default precision of 6. This more closely matches str(), and
6188 reduces surprises when adding alignment flags to the empty
6189 presentation type. This also affects the new complex.__format__ in
6190 the same way.
6191
Martin v. Löwis011e8422009-05-05 04:43:17 +00006192- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
6193
R. David Murrayb18500d2009-05-04 22:59:07 +00006194- Issue #5890: in subclasses of 'property' the __doc__ attribute was
6195 shadowed by classtype's, even if it was None. property now
6196 inserts the __doc__ into the subclass instance __dict__.
6197
Antoine Pitrou244651a2009-05-04 18:56:13 +00006198- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
6199 sequences. Patch by Nick Barnes and Victor Stinner.
6200
Martin v. Löwise0a2b722009-05-10 08:08:56 +00006201- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00006202
Benjamin Petersond2e0c792009-05-01 20:40:59 +00006203- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6204 received a new method, detach(). detach() disconnects the underlying stream
6205 from the buffer or text IO and returns it.
6206
Mark Dickinson33841c32009-05-01 15:37:04 +00006207- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6208 floats with absolute value over 1e50. Also remove length
6209 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6210 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006211
Eric Smith741191f2009-05-06 13:08:15 +00006212- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006213 format(complex(1, 2./3), '.5') now produces a sensible result.
6214
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006215- Issue #5864: Fix empty format code formatting for floats so that it
6216 never gives more than the requested number of significant digits.
6217
Eric Smith6dc46f52009-04-27 20:39:49 +00006218- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6219 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6220
Eric Smithcc32a112009-04-26 21:35:14 +00006221- Issue #5835: Deprecate PyOS_ascii_formatd.
6222
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006223- Issue #4971: Fix titlecase for characters that are their own
6224 titlecase, but not their own uppercase.
6225
Benjamin Peterson193152c2009-04-25 01:08:45 +00006226- Issue #5283: Setting __class__ in __del__ caused a segfault.
6227
Mark Dickinsonad476da2009-04-23 19:14:16 +00006228- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6229 z involves nans, infs or negative zeros.
6230
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006231- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006232
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006233- Issue #1869 (and many duplicates): make round(x, n) correctly
6234 rounded for a float x, by using the decimal <-> binary conversions
6235 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6236 consistently agrees with format(x, '.2f').
6237
Benjamin Petersonae937c02009-04-18 20:54:08 +00006238- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6239 some builtin types.
6240
Eric Smith0923d1d2009-04-16 20:16:10 +00006241- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6242
Eric Smith35e84722009-04-16 20:21:28 +00006243- Issue #5515: str.format() type 'n' combined with commas and leading
6244 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006245
6246- Implement PEP 378, Format Specifier for Thousands Separator, for
6247 floats.
6248
Mark Dickinson3370cce2009-04-17 22:40:53 +00006249- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006250 1e11, not 1e12. This avoids printing 13 significant digits in
6251 situations where only 12 of them are correct. Example problem
6252 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6253 long time.)
6254
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006255- Issue #1580: On most platforms, use a 'short' float repr: for a
6256 finite float x, repr(x) now outputs a string based on the shortest
6257 sequence of decimal digits that rounds to x. Previous behaviour was
6258 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006259 Another minor difference is that the new repr switches to
6260 exponential notation at 1e16 instead of the previous 1e17; this
6261 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006262
6263 There's a new sys attribute sys.float_repr_style, which takes
6264 the value 'short' to indicate that we're using short float repr,
6265 and 'legacy' if the short float repr isn't available for one
6266 reason or another.
6267
6268 The float repr change involves incorporating David Gay's 'perfect
6269 rounding' code into the Python core (it's in Python/dtoa.c). As a
6270 secondary consequence, all string-to-float and float-to-string
6271 conversions (including all float formatting operations) will be
6272 correctly rounded on these platforms.
6273
Georg Brandl5f90d792010-08-01 22:31:05 +00006274 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006275 this change does not apply.
6276
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006277- Issue #5759: float() didn't call __float__ on str subclasses.
6278
Georg Brandlabc38772009-04-12 15:51:51 +00006279- The string.maketrans() function is deprecated; there is a new static method
6280 maketrans() on the bytes and bytearray classes. This removes confusion about
6281 the types string.maketrans() is supposed to work with, and mirrors the
6282 methods available on the str class.
6283
R. David Murraydc6da8a2009-04-09 22:16:43 +00006284- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6285 its clarity and its speed.
6286
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006287- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006288 to avoid compiler warnings.
6289
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006290- Issue #3739: The unicode-internal encoder now reports the number of characters
6291 consumed like any other encoder (instead of the number of bytes).

6349 at once could hit the recursion limit if the mimetypes database hadn't been
6350 initialized before.
6351
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006352- Issue #5854: Updated __all__ to include some missing names and remove some

6362 instances.
6363
Mark Dickinsoncf63f2f2009-04-22 17:50:21 +00006364- Issue #5812: Fraction('1e6') is valid: more generally, any string
6365 that's valid for float() is now valid for Fraction(), with the
6366 exception of strings representing NaNs and infinities.

6372 results in a handle_expt_event call, not handle_read_event, and POLLERR
6373 and POLLNVAL now call handle_close, not handle_expt_event. Also,
6374 dispatcher now has an 'ignore_log_types' attribute for suppressing
6375 log messages, which is set to 'warning' by default.
6376
Matthias Klosea3d29e82009-04-07 13:13:10 +00006377- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for

Benjamin Peterson8f76b492009-04-03 22:22:42 +00006428- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
6429
Benjamin Peterson7fe98532009-04-02 00:33:55 +00006430- Issue #5499: The 'c' code for argument parsing functions now only accepts a
6431 byte, and the 'C' code only accepts a unicode character.
6432
Georg Brandl406b3d82009-04-11 21:24:37 +00006433- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
6434 when hitting the recursion limit under certain circumstances.
6435
Brett Cannon0759dd62009-04-01 18:13:07 +00006436- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.

6449
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006450- Issue #4688: Add a heuristic so that tuples and dicts containing only
6451 untrackable objects are not tracked by the garbage collector. This can
6452 reduce the size of collections and therefore the garbage collection overhead
6453 on long-running programs, depending on their particular use of datatypes.

6460 2**15 for the internal representation of integers, for performance
6461 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6462 --enable-big-digits option to configure, which overrides the
6463 default. Add sys.int_info structseq to provide information about
6464 the internal format.

6467 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
6468 and sizeof(Py_UNICODE) == 2.
6469
Eric Smith8ec90442009-03-14 12:29:34 +00006470- Issue #5237: Allow auto-numbered fields in str.format(). For

6472
Antoine Pitrou652e7072009-03-13 19:25:20 +00006473- Issue #5392: when a very low recursion limit was set, the interpreter would
6474 abort with a fatal error after the recursion limit was hit twice.
6475
Matthias Klose042f1332009-04-04 14:32:42 +00006476- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
6477 short file names.

6524 forever on incomplete input. That caused tarfile.open() to hang when used
6525 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6526 partial bzip2 compressed data.
6527
Mark Dickinson79f52032009-03-17 23:12:51 +00006528- Issue #2110: Add support for thousands separator and 'n' type

Vinay Sajip6268cbc2009-01-21 00:19:28 +00006638- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006639 having been closed (for instance, a read() call could return some
6640 previously buffered data). Patch by Dmitry Vasiliev.
6641
Antoine Pitrou05608432009-01-09 18:53:14 +00006642- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6643 flag to work properly. Furthermore, when specifying -u, the text stdout
6644 and stderr streams have line-by-line buffering enabled (the default being
6645 to buffer arbitrary chunks of data).
6646
Raymond Hettinger35631532009-01-09 03:58:09 +00006647- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6648 instead of ints (reducing its size from 4 to 8 times thereby reducing
6649 Python's overall memory).
6650
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006651- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6652 an existing .py counterpart, override the co_filename attributes of all
6653 code objects if the original filename is obsolete (which can happen if the
6654 file has been renamed, moved, or if it is accessed through different paths).
6655 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6656
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006657- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6658 one byte. Also fixes the meaning of len() so that it returns the number of
6659 items, rather than the size in bytes.
6660
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006661- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6662
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006663- Issue #4747: When the terminal does not use utf-8, executing a script with
6664 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6665
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006666- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6667 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006668
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006669- Issue #3680: Reference cycles created through a dict, set or deque iterator
6670 did not get collected.
6671
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006672- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6673 where the tp_hash and tp_dict slots are both NULL.
6674
Georg Brandlccc47b62008-12-28 11:44:14 +00006675- Issue #4759: None is now allowed as the first argument of
6676 bytearray.translate(). It was always allowed for bytes.translate().
6677
Skip Montanaro80072cb2008-12-23 03:51:14 +00006678- Added test case to ensure attempts to read from a file opened for writing
6679 fail.
6680
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006681- Issue #3106: Speedup some comparisons (str/str and int/int).
6682
Antoine Pitrouf289ae62008-12-18 11:06:25 +00006683- Issue #2183: Simplify and optimize bytecode for list, dict and set
6684 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6685
Antoine Pitrou621601a2008-12-17 23:18:19 +00006686- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6687 print elapsed times, not only when some objects are uncollectable /
6688 unreachable. Original patch by Neil Schemenauer.
6689
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006690- Issue #3439: Add a bit_length method to int.
6691
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006692- Issue #2173: When getting device encoding, check that return value of
6693 nl_langinfo is not the empty string. This was causing silent build
6694 failures on OS X.
6695
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006696- Issue #4597: Fixed several opcodes that weren't always propagating
6697 exceptions.
6698
6699- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006700 context manager returns a value that cannot be converted to a bool.
6701
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006702- Issue #4445: Replace "sizeof(PyBytesObject)" with
6703 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6704 bytes instances. On a typical machine this saves 3 bytes of memory
6705 (on average) per allocation of a bytes instance.
6706
Christian Heimesa872de52008-12-05 08:26:55 +00006707- Issue #4533: File read operation was dreadfully slow due to a slowly
6708 growing read buffer. Fixed by using the same growth rate algorithm as
6709 Python 2.x.
6710
Antoine Pitrou5504e892008-12-06 21:27:53 +00006711- Issue #4509: Various issues surrounding resize of bytearray objects to
6712 which there are buffer exports (e.g. memoryview instances).
6713
Georg Brandlf9734072008-12-07 15:30:06 +00006714- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6715 method on file objects with closefd=False. The file descriptor is still
6716 kept open but the file object behaves like a closed file. The ``FileIO``
6717 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006718
Antoine Pitroubc420402008-12-07 20:14:49 +00006719- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6720 larger than 1.
6721

6725
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006726- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6727 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6728 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6729 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00007049- Issue #5008: When a file is opened in append mode with the new IO library,
7050 do an explicit seek to the end of file (so that e.g. tell() returns the

7082 appropriately when it is being used via socket.makefile() objects
7083 rather than delaying the close by waiting for garbage collection to do it.
