Ned Deilycbfb9a52012-06-23 16:02:19 -0700593- Issue #13590: Improve support for OS X Xcode 4:
594 * Try to avoid building Python or extension modules with problematic
595 llvm-gcc compiler.
596 * Since Xcode 4 removes ppc support, extension module builds now
597 check for ppc compiler support and automatically remove ppc and
598 ppc64 archs when not available.
599 * Since Xcode 4 no longer install SDKs in default locations,
600 extension module builds now revert to using installed headers
601 and libs if the SDK used to build the interpreter is not
602 available.
603 * Update ./configure to use better defaults for universal builds;
604 in particular, --enable-universalsdk=yes uses the Xcode default
605 SDK and --with-universal-archs now defaults to "intel" if ppc
606 not available.

1964 Distutils-based packages with C extension modules may fail because
1965 Apple has removed gcc-4.2, the version used to build python.org
1966 64-bit/32-bit Pythons. If the user does not explicitly override
1967 the default C compiler by setting the CC environment variable,
1968 Distutils will now attempt to compile extension modules with clang
1969 if gcc-4.2 is required but not found. Also as a convenience, if
1970 the user does explicitly set CC, substitute its value as the default
1971 compiler in the Distutils LDSHARED configuration variable for OS X.
1972 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1973 SDK, neither of which are available in Xcode 4. This change does not
1974 attempt to override settings to support their use with Xcode 4.)

2700
Ned Deily657b2de2011-06-28 19:51:30 -07002701- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2702 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2703 interpreter process. This could cause failures in non-Distutils subprocesses
2704 and was unreliable since tests or user programs could modify the interpreter
2705 environment after Distutils set it. Instead, have Distutils set the the
2706 deployment target only in the environment of each build subprocess. It is
2707 still possible to globally override the default by setting
2708 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2709 greater or equal to the default value, the value with which the interpreter

Antoine Pitrou305bc9e2011-01-20 21:07:24 +00003888 filenames, at bootstrap, if the codec registry is not ready yet. It is still
3889 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
3890 for all file entries in the ZIP file.

3902 of HTTP 1.1.
Steven Bethardb0270112011-01-24 21:02:50 +00003903
3904- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00003905 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00003906 that for incoming headers which makes this behaviour now consistent in
3907 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00004003- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00004004 continuation line in the formatted value has no leading white space and looks
4005 like a header. Since Generator uses Header to format all headers, this check
4006 is made for all headers in any serialized message at serialization time. This
4007 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00004008
Antoine Pitrou67b212e2011-01-08 09:55:31 +00004009- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

Éric Araujof0ab5d62011-05-29 03:43:59 +02004016 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00004017 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00004018
Éric Araujof0ab5d62011-05-29 03:43:59 +02004019- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00004020 rfc2047-encoding header values with embedded newlines, leaving them without
4021 folding whitespace. It now uses the continuation_ws, as it does for
4022 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00004024- Issue #1777412, #10827: Changed the rules for 2-digit years. The
4025 time.asctime(), time.ctime() and time.strftime() functions will now format
4026 any year when ``time.accept2dyear`` is False and will accept years >= 1000
4027 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
4028 supported by the OS. With Visual Studio or on Solaris, the year is limited to
4029 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

5050 Py_Initialize().
5051
Georg Brandl27a28582010-10-10 09:49:21 +00005052- All SyntaxErrors now have a column offset and therefore a caret when the error

5062 with a non-empty format string. This is an effort to future-proof user
5063 code. If a derived class does not currently implement __format__ but later
5064 adds its own __format__, it would most likely break user code that had
5065 supplied a format string. This will be changed to a DeprecationWaring in
5066 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00005068- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

5070 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 +00005072- Issue #9210: Configure option --with-wctype-functions was removed. Using the
5073 functions from the libc caused the methods .upper() and lower() to become
5074 locale aware and created subtly wrong results.
5075
Georg Brandl27a28582010-10-10 09:49:21 +00005076- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Victor Stinner1205f272010-09-11 00:54:47 +00005078
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00005079- Issue #4617: Previously it was illegal to delete a name from the local
5080 namespace if it occurs as a free variable in a nested block. This limitation
5081 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
5082
Georg Brandl27a28582010-10-10 09:49:21 +00005083- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
5084 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
5085 Also, the "backslashreplace" error handler now joins surrogate pairs into a
5086 single character on UCS-2 builds.

5091
Antoine Pitrou079ce542010-09-08 12:37:10 +00005092- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00005121- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00005122 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00005123 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00005124 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00005149 retry the select() loop instead of bailing out. This is because select() can

Georg Brandl27a28582010-10-10 09:49:21 +00005232 it possible for the user to create self-referencing ordered dictionaries which
5233 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00005234 approach of using weakref proxies so that reference cycles never get created
5235 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00005278 * Update the seed() method to use all of the bits in a string instead of just
5279 the hash value. This makes better use of the seed value and assures the
5280 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00005282 * Improved the random()-->integer algorithm used in choice(), shuffle(),
5283 sample(), randrange(), and randint(). Formerly, it used int(n*random())
5284 which has a slight bias whenever n is not a power of two. Issue #9025.

5286 * Improved documentation of arguments to randrange(). Issue #9379.

5307 guaranteed to exist in all Python implementations and the names of hash
5308 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00005413- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
5414 now removed, since their effect was inexistent in 3.x (the default encoding is
5415 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00005416
Antoine Pitroub0fa8312010-09-01 15:10:12 +00005417- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

5421 platforms. Previously, it inlined only when using Microsoft Visual C.

5437 return characters from the full Unicode range, even on narrow unicode builds
5438 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
5439 in Python is that unicodedata.numeric() now returns the correct value for
5440 large code points, and repr() may consider more characters as printable.
5441
Victor Stinner6c00c142010-08-17 23:37:11 +00005442- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Victor Stinner47fcb5b2010-08-13 23:59:58 +00005458- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00005459 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
5460 objects are output as-is.

5464 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00005465
Georg Brandl649971e2010-09-05 17:06:50 +00005466- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
5467 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00005468
Georg Brandl649971e2010-09-05 17:06:50 +00005469- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an

5475 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00005476
Georg Brandl649971e2010-09-05 17:06:50 +00005477- Issue #9416: Fix some issues with complex formatting where the output with no
5478 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00005479
5480 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
5481 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

5824 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
5825 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions

Georg Brandl62069d32010-07-31 08:56:11 +00005869- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
5870 TypeError instead of giving a DeprecationWarning when a float is parsed using
5871 the 'L' code (for long long). (All other integer codes already raise
5872 TypeError in this case.)

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00005898- Issue #8748: Fix two issues with comparisons between complex and integer
5899 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00005900 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
5901 (2) The comparison raised an OverflowError for large integers, leading to
5902 unpredictable exceptions when combining integers and complex objects in sets

6204
Alexander Belopolskyf0f45142010-08-11 17:31:17 +00006205- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
6206 variable argument list. `Py_VA_COPY` is equivalent to C99
6207 `va_copy`, but available on all python platforms.
6208
Mark Dickinsone6fc7402010-08-06 18:55:26 +00006209- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
6210 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
6211 "step = -step" when reversing a slice.
6212
Georg Brandl62069d32010-07-31 08:56:11 +00006213- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the

Antoine Pitrou8689a102010-04-01 16:53:15 +00006221- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00006222 function declaration, which was kept for backwards compatibility reasons, is
6223 now removed (the macro was introduced in 1997!).

6233 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
6234 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00006235 to match the behaviour of the other integer format codes.
6236

Georg Brandl62069d32010-07-31 08:56:11 +00006245- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
6246 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
6247 accessing the d_type and d_name members of structures using PyDescr_COMMON.

6261
Georg Brandl62069d32010-07-31 08:56:11 +00006262- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6263 allocator will be automatically disabled when running under Valgrind. This
6264 gives improved memory leak detection when running under Valgrind, while taking
6265 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00006338- The default size of the re module's compiled regular expression cache has been

Antoine Pitrou3060c452010-08-13 16:27:38 +00006340 simply clearing the entire cache on overflow to forgetting the least recently
6341 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00006342 applications that use a lot of regular expressions and limits the impact of
6343 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00006597- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
6598 operation raises multiple signals and more than one of those signals is
6599 trapped, the specification determines the order in which the signals should be
6600 handled. In many cases this order wasn't being followed, leading to the wrong
6601 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00006640- Issue #8524: When creating an SSL socket, the timeout value of the original
6641 socket wasn't retained (instead, a socket with a positive timeout would be
6642 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00006643
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00006644- Issue #5103: SSL handshake would ignore the socket timeout and block

Barry Warsawd5f9bf52010-03-31 21:36:22 +00006765- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00006766 argument `-` which tells it to read files to compile from stdin. Each line is
6767 read on demand and the named file is compiled immediately. (Original patch by
6768 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00006774- Comparisons using one of <, <=, >, >= between a complex instance and a
6775 Fractions instance now raise TypeError instead of returning True/False. This
6776 makes Fraction <=> complex comparisons consistent with int <=> complex, float
6777 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00006824- subprocess.Popen now has restore_signals and start_new_session features. The
6825 default of restore_signals=True is a new behavior compared to earlier Python
6826 versions. This means that signals such as SIGPIPE are not ignored by default
6827 in subprocesses launched by Python (Issue #1652).

Antoine Pitroua32f9a22010-01-27 21:18:57 +00006918- Issue #7610: Reworked implementation of the internal

Georg Brandl62069d32010-07-31 08:56:11 +00006920 archive. The new implementation is significantly faster and can be wrapped in
Georg Brandl88b95f92012-05-06 11:24:06 +02006921 a ``io.BufferedReader`` object for more speedups. It also solves an

Brett Cannon69194272009-07-20 04:23:48 +00007258- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00007259 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
7260 PyPycLoader inherit from this class and provide implementations in relation to
7261 other methods required by the ABCs.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00007320- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00007321 compared to other unix systems. In particular, os.getgroups() does not reflect
7322 any changes made using os.setgroups() but basicly always returns the same
7323 information as the id command. os.getgroups() can now return more than 16
7324 groups on MacOSX.

7350 Prior to this change, timezone adjustment in utctimetuple() could produce
7351 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

7355 directive. When the ``%z`` directive is present in the format string, an
7356 aware ``datetime`` object is returned with ``tzinfo`` bound to a
7357 ``datetime.timezone`` instance constructed from the parsed offset. If both
7358 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
7359 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00007362 implementing ``datetime.tzinfo`` interface. Instances of the new class,
7363 ``datetime.timezone``, return fixed name and UTC offset from their
7364 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
7365 returns ``None``. A class attribute, ``utc`` contains an instance
7366 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00007393 the result is now always correctly rounded, and is equivalent to ``td /

Mark Dickinson865e01a2009-05-07 16:37:01 +00007972- Issue #5914: Add new C API function PyOS_string_to_double, and
7973 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.

7982
Eric Smith63376222009-05-05 14:04:18 +00007983- Issue #5920: For float.__format__, change the behavior with the

7985 to be like 'g' but with at least one decimal point and with a
7986 default precision of 12. Previously, the behavior the same but with
7987 a default precision of 6. This more closely matches str(), and
7988 reduces surprises when adding alignment flags to the empty
7989 presentation type. This also affects the new complex.__format__ in
7990 the same way.

R. David Murrayb18500d2009-05-04 22:59:07 +00007994- Issue #5890: in subclasses of 'property' the __doc__ attribute was
7995 shadowed by classtype's, even if it was None. property now
7996 inserts the __doc__ into the subclass instance __dict__.
7997
Antoine Pitrou244651a2009-05-04 18:56:13 +00007998- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00008003- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
8004 received a new method, detach(). detach() disconnects the underlying stream
8005 from the buffer or text IO and returns it.
8006
Mark Dickinson33841c32009-05-01 15:37:04 +00008007- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
8008 floats with absolute value over 1e50. Also remove length
8009 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
8010 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00008012- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00008013 format(complex(1, 2./3), '.5') now produces a sensible result.
8014
Mark Dickinsond3ca5572009-04-29 18:47:07 +00008015- Issue #5864: Fix empty format code formatting for floats so that it

8017
Eric Smith6dc46f52009-04-27 20:39:49 +00008018- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

8029 z involves nans, infs or negative zeros.
8030

Mark Dickinsonc6300392009-04-20 21:38:00 +00008032
Mark Dickinsone6a076d2009-04-18 11:48:33 +00008033- Issue #1869 (and many duplicates): make round(x, n) correctly
8034 rounded for a float x, by using the decimal <-> binary conversions
8035 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
8036 consistently agrees with format(x, '.2f').
8037
Benjamin Petersonae937c02009-04-18 20:54:08 +00008038- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
8039 some builtin types.
8040
Eric Smith0923d1d2009-04-16 20:16:10 +00008041- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
8042
Eric Smith35e84722009-04-16 20:21:28 +00008043- Issue #5515: str.format() type 'n' combined with commas and leading
8044 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00008045
8046- Implement PEP 378, Format Specifier for Thousands Separator, for
8047 floats.
8048
Mark Dickinson3370cce2009-04-17 22:40:53 +00008049- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008050 1e11, not 1e12. This avoids printing 13 significant digits in
8051 situations where only 12 of them are correct. Example problem
8052 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
8053 long time.)
8054
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008055- Issue #1580: On most platforms, use a 'short' float repr: for a
8056 finite float x, repr(x) now outputs a string based on the shortest
8057 sequence of decimal digits that rounds to x. Previous behaviour was
8058 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00008059 Another minor difference is that the new repr switches to
8060 exponential notation at 1e16 instead of the previous 1e17; this
8061 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008062
8063 There's a new sys attribute sys.float_repr_style, which takes
8064 the value 'short' to indicate that we're using short float repr,
8065 and 'legacy' if the short float repr isn't available for one
8066 reason or another.
8067
8068 The float repr change involves incorporating David Gay's 'perfect
8069 rounding' code into the Python core (it's in Python/dtoa.c). As a
8070 secondary consequence, all string-to-float and float-to-string
8071 conversions (including all float formatting operations) will be
8072 correctly rounded on these platforms.
8073
Georg Brandl5f90d792010-08-01 22:31:05 +00008074 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008075 this change does not apply.
8076
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00008077- Issue #5759: float() didn't call __float__ on str subclasses.
8078
Georg Brandlabc38772009-04-12 15:51:51 +00008079- The string.maketrans() function is deprecated; there is a new static method
8080 maketrans() on the bytes and bytearray classes. This removes confusion about
8081 the types string.maketrans() is supposed to work with, and mirrors the
8082 methods available on the str class.
8083
R. David Murraydc6da8a2009-04-09 22:16:43 +00008084- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

8086
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008087- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``

Walter Dörwald8dc33d52009-05-06 14:41:26 +00008090- Issue #3739: The unicode-internal encoder now reports the number of characters

8251 untrackable objects are not tracked by the garbage collector. This can
8252 reduce the size of collections and therefore the garbage collection overhead
8253 on long-running programs, depending on their particular use of datatypes.

8366
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00008367- Issue #5249: time.strftime returned malformed string when format string
8368 contained non ascii character on windows.
8369
Benjamin Petersonf5b52242009-03-02 23:31:26 +00008370- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the

8374 rotating the object pointer by 4 bits to the right.
8375
Mark Dickinson87ec0852009-02-09 17:15:59 +00008376- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
8377 it now forces its argument to double before testing for infinity.
8378
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00008379- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
8380 returns a non-number type.
8381
Benjamin Peterson87618552009-02-08 15:00:52 +00008382- Issue #5182: Removed memoryview.__str__.
8383
Mark Dickinsonc008a172009-02-01 13:59:22 +00008384- Issue #1717: Removed builtin cmp() function, dropped tp_compare
8385 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00008386 the type definition cmpfunc. The tp_compare slot has been renamed
8387 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00008388
Georg Brandl1cdd83c2009-04-05 20:24:29 +00008389- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00008390 were suppressing all exceptions. These include list() and bytearray().
8391
Mark Dickinson1124e712009-01-28 21:25:58 +00008392- Issue #4707: round(x, n) now returns an integer if x is an integer.
8393 Previously it returned a float.
8394
Antoine Pitroub52ec782009-01-25 16:34:23 +00008395- Issue #4753: By enabling a configure option named '--with-computed-gotos'
8396 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
8397 evaluation loop is compiled with a new dispatch mechanism which gives
8398 speedups of up to 20%, depending on the system, on various benchmarks.
8399
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00008400- Issue #4874: Most builtin decoders now reject unicode input.

8408 optional module state data.
8409
Mark Dickinson8055afd2009-01-17 10:04:45 +00008410- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008411 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00008412
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00008413- Issue #4935: The overflow checking code in the expandtabs() method common
8414 to str, bytes and bytearray could be optimized away by the compiler, letting
8415 the interpreter segfault instead of raising an error.
8416
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00008417- Issue #3720: Fix a crash when an iterator modifies its class and removes its
8418 __next__ method.
8419
Mark Dickinsone5e298f2009-01-12 20:49:19 +00008420- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
8421 function no longer attempt to call the __long__ slot to convert an object
8422 to an integer. Only the __int__ and __trunc__ slots are examined.
8423
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00008424- Issue #4893: Use NT threading on CE.
8425
Martin v. Löwisec59d042009-01-12 07:59:10 +00008426- Issue #4915: Port sysmodule to Windows CE.
8427
Antoine Pitrouab868312009-01-10 15:40:25 +00008428- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
8429 common cases are optimized thanks to a dedicated fast path and a moderate
8430 amount of loop unrolling.
8431
Antoine Pitrou14b78f52009-01-09 22:27:08 +00008432- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
8433 collecting the oldest generation) so that allocating lots of objects without
8434 destroying them does not show quadratic performance. Based on a proposal by
8435 Martin von Löwis at
8436 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
8437
Vinay Sajip6268cbc2009-01-21 00:19:28 +00008438- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00008439 having been closed (for instance, a read() call could return some
8440 previously buffered data). Patch by Dmitry Vasiliev.
8441
Antoine Pitrou05608432009-01-09 18:53:14 +00008442- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
8443 flag to work properly. Furthermore, when specifying -u, the text stdout
8444 and stderr streams have line-by-line buffering enabled (the default being
8445 to buffer arbitrary chunks of data).
8446
Raymond Hettinger35631532009-01-09 03:58:09 +00008447- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
8448 instead of ints (reducing its size from 4 to 8 times thereby reducing
8449 Python's overall memory).
8450
Antoine Pitroud35cbf62009-01-06 19:02:24 +00008451- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
8452 an existing .py counterpart, override the co_filename attributes of all
8453 code objects if the original filename is obsolete (which can happen if the
8454 file has been renamed, moved, or if it is accessed through different paths).
8455 Patch by Ziga Seilnacht and Jean-Paul Calderone.
8456
Antoine Pitrouc3b39242009-01-03 16:59:18 +00008457- Issue #4580: Fix slicing of memoryviews when the item size is greater than
8458 one byte. Also fixes the meaning of len() so that it returns the number of
8459 items, rather than the size in bytes.
8460
Martin v. Löwis5c88d812009-01-02 20:47:48 +00008461- Issue #4075: Use OutputDebugStringW in Py_FatalError.
8462
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00008463- Issue #4747: When the terminal does not use utf-8, executing a script with
8464 non-ascii characters in its name could fail with a "SyntaxError: None" error.
8465
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008466- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
8467 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00008468
Antoine Pitrou7ddda782009-01-01 15:35:33 +00008469- Issue #3680: Reference cycles created through a dict, set or deque iterator
8470 did not get collected.
8471
Nick Coghlanf1f2f682008-12-30 07:29:12 +00008472- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
8473 where the tp_hash and tp_dict slots are both NULL.
8474
Georg Brandlccc47b62008-12-28 11:44:14 +00008475- Issue #4759: None is now allowed as the first argument of
8476 bytearray.translate(). It was always allowed for bytes.translate().
8477
Skip Montanaro80072cb2008-12-23 03:51:14 +00008478- Added test case to ensure attempts to read from a file opened for writing
8479 fail.
8480
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00008481- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00008483- Issue #2183: Simplify and optimize bytecode for list, dict and set
8484 comprehensions. Original patch for list comprehensions by Neal Norwitz.
8485
Antoine Pitrou621601a2008-12-17 23:18:19 +00008486- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
8487 print elapsed times, not only when some objects are uncollectable /
8488 unreachable. Original patch by Neil Schemenauer.
8489
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00008490- Issue #3439: Add a bit_length method to int.
8491
Mark Dickinsonda2706b2008-12-11 18:03:03 +00008492- Issue #2173: When getting device encoding, check that return value of
8493 nl_langinfo is not the empty string. This was causing silent build
8494 failures on OS X.
8495
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00008496- Issue #4597: Fixed several opcodes that weren't always propagating
8497 exceptions.
8498
8499- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00008500 context manager returns a value that cannot be converted to a bool.
8501
Mark Dickinsonfd24b322008-12-06 15:33:31 +00008502- Issue #4445: Replace "sizeof(PyBytesObject)" with
8503 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
8504 bytes instances. On a typical machine this saves 3 bytes of memory
8505 (on average) per allocation of a bytes instance.
8506
Christian Heimesa872de52008-12-05 08:26:55 +00008507- Issue #4533: File read operation was dreadfully slow due to a slowly
8508 growing read buffer. Fixed by using the same growth rate algorithm as
8509 Python 2.x.
8510
Antoine Pitrou5504e892008-12-06 21:27:53 +00008511- Issue #4509: Various issues surrounding resize of bytearray objects to
8512 which there are buffer exports (e.g. memoryview instances).
8513
Georg Brandlf9734072008-12-07 15:30:06 +00008514- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
8515 method on file objects with closefd=False. The file descriptor is still
8516 kept open but the file object behaves like a closed file. The ``FileIO``
8517 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00008518
Antoine Pitroubc420402008-12-07 20:14:49 +00008519- Issue #4569: Interpreter crash when mutating a memoryview with an item size
8520 larger than 1.

8525
Walter Dörwaldc1651a02009-05-03 22:55:55 +00008526- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
8527 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
8528 step. This avoids problems with counting UTF-8 bytes that ignores the effect
8529 of using the replace error handler in PyUnicode_DecodeUTF8().

Guilherme Polo2a998fa2009-06-21 17:40:07 +00009134- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
9135 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
9136 the same behaviour as test_ttkguionly (and now also test_tk) which is to
9137 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00009139- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00009140 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00009141 from test support, which does the conversion.
