Ned Deily18fae3f2013-01-31 01:24:55 -0800917- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
918 In particular, fix extension module build failures when trying to use
919 32-bit-only installer Pythons on systems with Xcode 4 (currently
920 OS X 10.8, 10.7, and optionally 10.6).
921 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
922 * Since Xcode 4 removes ppc support, extension module builds now
923 check for ppc compiler support and by default remove ppc and
924 ppc64 archs when they are not available.
925 * Extension module builds now revert to using system installed
926 headers and libs (/usr and /System/Library) if the SDK used
927 to build the interpreter is not installed or has moved.
928 * Try to avoid building extension modules with deprecated
929 and problematic Apple llvm-gcc compiler. If original compiler
930 is not available, use clang instead by default.

1215
Mark Dickinsondbbed042011-09-19 16:38:08 +01001216- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1217 int.__pow__. These overflow checks were causing int.__pow__ to produce
1218 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001219 compiler optimizing the check away. Also fix similar overflow checks
1220 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1221 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02001232- Issue #12149: Update the method cache after a type's dictionnary gets
1233 cleared by the garbage collector. This fixes a segfault when an instance
1234 and its type get caught in a reference cycle, and the instance's
1235 deallocator calls one of the methods on the type (e.g. when subclassing
1236 IOBase). Diagnosis and patch by Davide Rizzo.

Victor Stinnerd3c7e172011-05-30 23:49:13 +02001244- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +02001245 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
1246 raw_input() interrupted by CTRL+c.

Łukasz Langa7a153902011-10-18 17:16:00 +02001248- Issue #10860: httplib now correctly handles an empty port after port

Florent Xiclunac2279652012-02-12 14:49:03 +01001289- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001290 has left two versions of customize_compiler, the original in
1291 distutils.sysconfig and another copy in distutils.ccompiler, with some
1292 parts of distutils calling one and others using the other.
1293 Complete the revert back to only having one in distutils.sysconfig as
1294 is the case in 3.x.
1295
Ned Deily0d0ea482012-02-10 12:59:06 +01001296- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1297 Distutils-based packages with C extension modules may fail because
1298 Apple has removed gcc-4.2, the version used to build python.org
1299 64-bit/32-bit Pythons. If the user does not explicitly override
1300 the default C compiler by setting the CC environment variable,
1301 Distutils will now attempt to compile extension modules with clang
1302 if gcc-4.2 is required but not found. Also as a convenience, if
1303 the user does explicitly set CC, substitute its value as the default
1304 compiler in the Distutils LDSHARED configuration variable for OS X.
1305 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1306 SDK, neither of which are available in Xcode 4. This change does not
1307 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001580- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1581 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1582 interpreter process. This could cause failures in non-Distutils subprocesses
1583 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001584 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001585 deployment target only in the environment of each build subprocess. It is
1586 still possible to globally override the default by setting
1587 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1588 greater or equal to the default value, the value with which the interpreter
1589 was built.

1616
Barry Warsawc5643282011-07-19 17:06:30 -04001617- sys.setcheckinterval() now updates the current ticker count as well as
1618 updating the check interval, so if the user decreases the check interval,
1619 the ticker doesn't have to wind down to zero from the old starting point
1620 before the new interval takes effect. And if the user increases the
1621 interval, it makes sure the new limit takes effect right away rather have an
1622 early task switch before recognizing the new interval.

2574 This prevents user-created self-referencing ordered dictionaries from
2575 becoming permanently uncollectable GC garbage. The downside is that

3036
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003037- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3038 start byte and the continuation byte(s) are now considered invalid, instead
3039 of the number of bytes specified by the start byte.
3040 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3041 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3042 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003051- Issue #8748: Fix two issues with comparisons between complex and integer
3052 objects. (1) The comparison could incorrectly return True in some cases
3053 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3054 (2) The comparison raised an OverflowError for large integers, leading
3055 to unpredictable exceptions when combining integers and complex objects
3056 in sets or dicts.
3057
Mark Dickinson81336372010-05-30 12:12:25 +00003058- Issue #5211: Implicit coercion for the complex type is now completely

3196 non-float non-integer argument is now converted to an integer (if possible)

3250 operation raises multiple signals and more than one of those signals is
3251 trapped, the specification determines the order in which the signals should be
3252 handled. In many cases this order wasn't being followed, leading to the wrong

3420Core and Builtins
3421-----------------
3422
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003423- Issue #7301: Add environment variable $PYTHONWARNINGS.
3424
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003425- Issue #8329: Don't return the same lists from select.select when no fds are
3426 changed.
3427
Georg Brandlfee0f442010-05-22 21:26:21 +00003428- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003429 on 64-bit machines. The shift count for either left or right shift is
3430 permitted to be up to sys.maxsize.
3431
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003432- Ensure that tokenization of identifiers is not affected by locale.
3433
Georg Brandlfee0f442010-05-22 21:26:21 +00003434- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003435
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003436- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3437
Georg Brandlfee0f442010-05-22 21:26:21 +00003438- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3439 with a non-empty format string. This is an effort to future-proof user
3440 code. If a derived class does not currently implement __format__ but later
3441 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003442 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003443 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003444
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003445- Issue #8268: Old-style classes (not just instances) now support weak
3446 references.
3447

3449 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00003450
Victor Stinnerc7790ed2010-03-22 12:36:28 +00003451- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00003453- Issue #6474: Make error message from passing an inadequate number of keyword
3454 arguments to a function correct.
3455
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00003456- Issue #8164: Don't allow lambda functions to have a docstring.
3457
Victor Stinner66644262010-03-10 22:30:19 +00003458- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003459 (SIGINT). If an error occurs while importing the site module, the error is
3460 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003461 module.
3462
Collin Winter001a3952010-03-18 21:54:01 +00003463- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00003468- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
3469
Antoine Pitrouf9de5342010-04-05 21:35:07 +00003470- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00003471 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
3472 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00003474- Issue #8310: Allow dis to examine new style classes.
3475
Georg Brandlfee0f442010-05-22 21:26:21 +00003476- Issue #8257: The Decimal construct now accepts a float instance directly,
3477 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003478
3479 >>> Decimal(1.1)
3480 Decimal('1.100000000000000088817841970012523233890533447265625')
3481
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003482- collections.Counter() now supports a subtract() method.
3483
Georg Brandlfee0f442010-05-22 21:26:21 +00003484- The functools module now has a total_ordering() class decorator to simplify
3485 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003486
Georg Brandlfee0f442010-05-22 21:26:21 +00003487- The functools module also adds cmp_to_key() as a tool to transition old-style
3488 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003489
Georg Brandlfee0f442010-05-22 21:26:21 +00003490- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3491 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003492
Georg Brandlfee0f442010-05-22 21:26:21 +00003493- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3494 InvalidOperation instead of returning False. (Comparisons involving a quiet
3495 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3496 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003497
Georg Brandlfee0f442010-05-22 21:26:21 +00003498- Issue #2531: Comparison operations between floats and Decimal instances now
3499 return a result based on the numeric values of the operands; previously they
3500 returned an arbitrary result based on the relative ordering of id(float) and
3501 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003502
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003503- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003504 argument `-` which tells it to read files to compile from stdin. Each line is
3505 read on demand and the named file is compiled immediately. (Original patch by
3506 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003507
Georg Brandlfee0f442010-05-22 21:26:21 +00003508- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
3509 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00003511- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3512 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003513 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003514
Georg Brandlfee0f442010-05-22 21:26:21 +00003515- Comparisons using one of <, <=, >, >= between a complex instance and a
3516 Fractions instance now raise TypeError instead of returning True/False. This
3517 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3518 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003519
Michael Foorde6410c52010-03-29 20:04:23 +00003520- Addition of ``WeakSet`` to the ``weakref`` module.

3528
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003529- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003530 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3531 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003532
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003533- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3534 deprecated.
3535
Georg Brandlfee0f442010-05-22 21:26:21 +00003536- Issue #7860: platform.uname now reports the correct 'machine' type when Python
3537 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00003538

3543 existing at the same time, causing a Unicode error when configuration code
3544 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00003545
Georg Brandlfee0f442010-05-22 21:26:21 +00003546- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
3547 when logging occurs.

Antoine Pitroueee91cd2010-03-26 19:27:16 +00003549- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
3550 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
3551 reads and writes are always retried by OpenSSL itself.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003573- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003574 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3575 log file to compute the next rollover time. If the log file does not exist,
3576 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003577

Georg Brandlba83f822010-03-14 09:50:54 +00003586- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3587 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3588 This is a behavior change, so email's minor version number is now bumped, to

Georg Brandlba83f822010-03-14 09:50:54 +00003622- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3623 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3624 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003625 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3626 inconsistent: __int__ was used for some integer codes but not for others, and
3627 the set of integer codes for which it was used differed between native packing
3628 and standard packing.)

4033-----------------
4034
Georg Brandlba83f822010-03-14 09:50:54 +00004035- The ``__complex__()`` method is now looked up on the class of instances to
4036 make it consistent with other special methods.

4040
Mark Dickinson1b34d252010-01-01 17:27:30 +00004041- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004042 DeprecationWarning when passed a float argument where an integer was expected.
4043 These functions and methods now raise TypeError instead. The majority of the
4044 effects of this change are in the extension modules, but some core functions
4045 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4046 and many unicode/str methods.

4060 of integers: the result of a/b is now correctly rounded for ints a and b (at
4061 least on IEEE 754 platforms), and in particular does not depend on the
4062 internal representation of a long.

4070
Georg Brandlba83f822010-03-14 09:50:54 +00004071 These executables now work properly with the arch(1) command: ``arch -ppc
4072 python`` will start a universal binary version of python in PPC mode (unlike

4213 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004214
Georg Brandlba83f822010-03-14 09:50:54 +00004215- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4216 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00004229- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4230 decimal string that's guaranteed to round back to x under correct rounding
4231 (with round-half-to-even rounding mode). Previously it gave a string based on
4232 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4233 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4234 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004235
Georg Brandlba83f822010-03-14 09:50:54 +00004236- Issue #7117: On almost all platforms: float-to-string and string-to-float
4237 conversions within Python are now correctly rounded. Places these conversions
4238 occur include: str for floats and complex numbers; the float and complex
4239 constructors; old-style and new-style numeric formatting; serialization and
4240 deserialization of floats and complex numbers using marshal, pickle and json;
4241 parsing of float and imaginary literals in Python code; Decimal-to-float
4242 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004243
Georg Brandlba83f822010-03-14 09:50:54 +00004244 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4245 providing correctly-rounded strtod and dtoa C functions. This code is
4246 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4247 the C compiler. There may be a small number of platforms on which correct
4248 operation of this code cannot be guaranteed, so the code is not used: notably,
4249 this applies to platforms where the C double format is not IEEE 754 binary64,
4250 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4251 and Python's configure script is unable to determine how to change the FPU
4252 precision. On these platforms conversions use the platform strtod and dtoa,
4253 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004255- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4256 uses the correctly-rounded string <-> float conversions described above (when
4257 available), and so produces correctly rounded results that will display nicely
4258 under the float repr. There are two related small changes: (1) round now
4259 accepts any class with an ``__index__()`` method for its second argument (but
4260 no longer accepts floats for the second argument), and (2) an excessively
4261 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4262 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004404
Georg Brandlba83f822010-03-14 09:50:54 +00004405 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4406 (2) parsing of strings representing infinities and nans was locale aware; and
4407 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00004408
Georg Brandlba83f822010-03-14 09:50:54 +00004409- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4410 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4411 but with at least one decimal point and with a default precision
4412 of 12. Previously, the behavior the same but with a default precision of 6.
4413 This more closely matches ``str()``, and reduces surprises when adding
4414 alignment flags to the empty presentation type. This also affects the new
4415 complex.__format__ in the same way.
4416
4417- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4418 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00004480 untrackable objects are not tracked by the garbage collector. This can reduce

4489 internal representation of integers, for performance reasons. Base 2**30 is
4490 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl6425a2f2008-12-28 11:54:53 +00004578- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00004579 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00004580
Skip Montanarof205c132008-12-23 03:30:15 +00004581- Added test case to ensure attempts to read from a file opened for writing
4582 fail.
4583
Georg Brandlba83f822010-03-14 09:50:54 +00004584- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
4585 elapsed times, not only when some objects are uncollectable/unreachable.
4586 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00004587
Mark Dickinson1a707982008-12-17 16:14:37 +00004588- Issue #3439: Add a bit_length method to int and long.
4589
Georg Brandlba83f822010-03-14 09:50:54 +00004590- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
4591 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00004592
Georg Brandlba83f822010-03-14 09:50:54 +00004593- Issue #4597: Fixed exception handling when the __exit__ function of a context
4594 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00004595
Georg Brandlba83f822010-03-14 09:50:54 +00004596- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00004597
Georg Brandlba83f822010-03-14 09:50:54 +00004598- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4599 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4600 instances. On a typical machine this saves 3 bytes of memory (on average) per
4601 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00004602
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004603- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4604 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4605 instead of throwing a MemoryError.
4606
Georg Brandlba83f822010-03-14 09:50:54 +00004607- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4608 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00004609
Benjamin Petersonc078f922008-11-21 22:27:24 +00004610- Issue #4367: Python would segfault during compiling when the unicodedata
4611 module couldn't be imported and \N escapes were present.
4612
Georg Brandlba83f822010-03-14 09:50:54 +00004613- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4614 file objects with closefd=False. The file descriptor is still kept open but
4615 the file object behaves like a closed file. The ``FileIO`` object also got a
4616 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00004617
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004618- Issue #4348: Some bytearray methods returned that didn't cause any change to
4619 the bytearray, returned the same bytearray instead of a copy.
4620
Georg Brandlba83f822010-03-14 09:50:54 +00004621- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00004623- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
4624
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00004625- Issue #4048: The parser module now correctly validates relative imports.
4626
Benjamin Petersondcee09d2008-10-31 02:16:05 +00004627- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
4628 exec statement.
4629
Georg Brandlba83f822010-03-14 09:50:54 +00004630- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
4631 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00004632
Benjamin Petersonbdca9422008-10-26 20:21:13 +00004633- Issue #4209: Enabling unicode_literals and the print_function in the same
4634 __future__ import didn't work.
4635
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004636- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004637 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004638
Georg Brandlba83f822010-03-14 09:50:54 +00004639- On windows, ``os.chdir()`` given unicode was not working if
4640 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4641 this code path is really executed because I cannot move to such directory on
4642 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004643
Georg Brandlba83f822010-03-14 09:50:54 +00004644- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4645 element is temporarily replaced with an equivalent frozenset. But the
4646 eventual KeyError would always report the empty ``frozenset()`` as the missing
4647 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00004648
Georg Brandlba83f822010-03-14 09:50:54 +00004649- Issue #4509: Various issues surrounding resize of bytearray objects to which
4650 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00004651
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00004652- Issue #4748: Lambda generators no longer return a value.

4655
Gregory P. Smithae91d092009-03-02 05:13:57 +00004656- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
4657
Georg Brandlba83f822010-03-14 09:50:54 +00004658- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
4659 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00004660
Matthias Klose91a3b9e2009-04-05 21:19:13 +00004661- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
4662 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00004663
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00004664- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
4665 returned them on 64bit platforms.
4666
Walter Dörwalded960ac2009-05-03 22:36:33 +00004667- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4668 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4669 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4670 of using the replace error handler in PyUnicode_DecodeUTF8().
4671
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004672- Issue #3739: The unicode-internal encoder now reports the number of characters
4673 consumed like any other encoder (instead of the number of bytes).
4674
Georg Brandlba83f822010-03-14 09:50:54 +00004675- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4676 allocator will be automatically disabled when running under Valgrind. This
4677 gives improved memory leak detection when running under Valgrind, while taking
4678 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00004703- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
4704 ownership when the group is not forced, because the group may be different
4705 from the user's group and inherit from its container when the test is run.

4749 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00004750 __main__.py file. This allows applications that run other Python scripts to

6044
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006045- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6046 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6047 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6048 ``printf`` function, whereas PyString_FromFormat has an independent
6049 implementation and uses "%zd" on all platforms for size_t values.
6050 This makes a difference on win64, where ``printf`` needs "%Id" to display
6051 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006053- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6057 object; previously an int would be returned for small values. the __long__
6058 method is allowed to return either an int or a long, but the behaviour of
6059 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006061- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00006067 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006068 was correctly parsed but parsing of subsequent arguments failed.
6069
Vinay Sajip35e3b032008-09-01 14:33:59 +00006070- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006071 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6072 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6073 when given a tuple of classes as second argument, were looking up
6074 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6075 type object.
6076
Neal Norwitz18aa3882008-08-24 05:04:52 +00006077- Fix crashes on memory allocation failure found with failmalloc.

6220-----------------
6221
Guido van Rossumf8402962008-08-20 15:01:50 +00006222- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6223 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6224 extensions do not automatically benefit from the class attribute
6225 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6226 to their tp_flags field if they care. This is a backwards
6227 compatibility feature; in 3.0, all types will use the cache by
6228 default.
6229
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006230- Keyword arguments can now follow starred arguments. (``f(a, *args,
6231 keyword=23)`` is now valid syntax.)

Thomas Heller0ad5ae02008-08-19 19:25:04 +00006233- ctypes function pointers that are COM methods have a boolean True
6234 value again.
6235
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006236- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6237 by denying s# to parse objects that have a releasebuffer procedure,
6238 and introducing s*.
6239
Georg Brandl1e13ea92008-08-11 09:07:59 +00006240- Issue #3537: Fix an assertion failure when an empty but presized dict
6241 object was stored in the freelist.
6242
Mark Dickinsonb6467572008-08-04 21:30:09 +00006243- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6244 ValueError consistently across platforms.
6245
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006246- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6247 (64bit Unix, for example), unichr() would truncate its argument and return
6248 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6249
Neal Norwitze7d8be82008-07-31 17:17:14 +00006250- Apply security patches from Apple.
6251
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006252- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6253 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6254
Antoine Pitrou92f82162008-07-25 22:22:08 +00006255- Issue #1819: function calls with several named parameters are now on
6256 average 35% faster (as measured by pybench).
6257
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006258- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6259 the python debugger steps into a class statement: the free variables (local
6260 variables defined in an outer scope) would be deleted from the outer scope.
6261
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006262- Issue #2620: Overflow checking when allocating or reallocating memory
6263 was not always being done properly in some python types and extension
6264 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6265 all been updated to perform better checks and places in the code that
6266 would previously leak memory on the error path when such an allocation
6267 failed have been fixed.

6273
Benjamin Petersone977ad42008-08-20 01:42:01 +00006274- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6275 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6276
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006277- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6278 version reported by these tools does not necessarily follow the python
6279 version numbering scheme, so the module is less strict when parsing it.
6280
Nick Coghlanf70385a2008-08-18 12:42:46 +00006281- Issue #2235: Added Py3k warnings for types which will become unhashable
6282 under the stricter __hash__ inheritance rules in 3.0. Several types
6283 which did not meet the rules for hash invariants and were already
6284 unhashable in 3.0 have now been explicitly flagged as unhashable in
6285 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6286 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6287
Brett Cannon88f801d2008-08-18 00:46:22 +00006288- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006316- Issue #3476: binary buffered reading through the new "io" library is now
6317 thread-safe.
6318
Brett Cannonbf3157b2008-08-14 05:00:03 +00006319- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6320 since mimetools itself is deprecated. Because modules are cached, all
6321 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6322
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006323- Issue #3134: shutil referenced undefined WindowsError symbol.

6332 a MemoryError rather than silently stop the iteration.
6333
Guido van Rossum59ce9012008-08-09 14:55:34 +00006334- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6335 to _sre.compile() will now be rejected. This should not affect anybody
6336 since the re.compile() function never generates invalid re-bytecode.
6337
Skip Montanaroa032bf42008-08-08 22:52:51 +00006338- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6339 upon first access it can be automatically initialized from the csv file if
6340 it wasn't initialized during instantiation.
6341
Brett Cannon3aa2a492008-08-06 22:28:09 +00006342- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6343 the reload() built-in has been removed.
6344
Brett Cannon7e30b672008-08-04 21:52:25 +00006345- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006346 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006357 asking for a specific length. This problem only affected files opened
6358 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006359

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006383- Issue #3394: zipfile.writestr sets external attributes when passed a
6384 file name rather than a ZipInfo instance, so files are extracted with
6385 mode 0600 rather than 000 under Unix.
6386
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006387- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6388 argument in python 2.5, this broke code that subclassed Popen to include its
6389 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006399- Issue #2235: the C API function PyObject_HashNotImplemented and its
6400 interaction with the tp_hash slot (added in 2.6b2) are now documented
6401
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006402- Issue #643841: The language reference now provides more detailed
6403 coverage of the lookup process for special methods. The disclaimers
6404 regarding lack of coverage of new-style classes have also been
6405 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006413Core and Builtins
6414-----------------
6415
Georg Brandl3e483f62008-07-16 22:57:41 +00006416- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6417 its methods now allow for items objects that can be converted to
6418 an integer using operator.index().
6419
Mark Dickinson64b7e502008-07-16 09:40:03 +00006420- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6421 produced a ValueError instead of giving the correct float.
6422
Eric Smitha5fa5a22008-07-16 00:11:49 +00006423- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6424 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6425
Mark Dickinson7103aa42008-07-15 19:08:33 +00006426- Issue #3008: the float type has a new instance method 'float.hex'
6427 and a new class method 'float.fromhex' to convert floating-point
6428 numbers to and from hexadecimal strings, respectively.
6429
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006430- Issue #2235: __hash__ is once again inherited by default. To allow
6431 collections.Hashable to remain meaningful in the presence of the
6432 default hash implementation (object.__hash__), it is now possible
6433 to explicit block inheritance of hash by setting __hash__=None at
6434 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6435 level.
6436
Nick Coghlanb028f502008-07-13 14:52:36 +00006437- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6438 the parent module cannot be found while performing an absolute import.
6439 This means that an incorrectly defined __package__ attribute will
6440 now only prevent relative imports in that module rather than causing
6441 all imports from that module to fail.
6442
Nick Coghlan14ff9942008-07-08 14:21:42 +00006443- Issue #2517: Allow unicode messages in Exceptions again by correctly
6444 bypassing the instance dictionary when looking up __unicode__ on
6445 new-style classes.
6446
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006447- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6448 set to a custom object whose write() method happens to install
6449 another file in sys.stdout.
6450
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006451- Issue #3088: Corrected a race condition in classes derived from
6452 threading.local: the first member set by a thread could be saved in
6453 another thread's dictionary.
6454
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006455- Issue #3004: Minor change to slice.indices(): the start and stop
6456 arguments are now treated identically, making the behaviour easier
6457 to describe and understand. For example, slice(None, -10,
6458 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6459 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6460 10, -1).
6461
Georg Brandl278fc502008-07-19 12:46:12 +00006462- Issue #3219: Calling a function with repeated keyword arguments,
6463 f(a=2, a=23), would not cause a syntax error. This was a regression
6464 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006465
Georg Brandl278fc502008-07-19 12:46:12 +00006466- Issue #2862: Make int and float freelist management consistent with
6467 other freelists. Changes their CompactFreeList apis into
6468 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006469

6471-------
6472
Thomas Heller57adf222008-08-14 19:10:48 +00006473- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6474 api functions without holding the GIL, which could lead to a fatal
6475 error when they failed.
6476
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006477- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6486 ForkingPickler.register() to resolve conflict with ctypes.
6487
Vinay Sajip51e65192008-07-18 09:01:10 +00006488- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00006490- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6491 a valid dlerror() message.
6492
Thomas Heller2bad6572008-07-15 17:19:50 +00006493- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6494 incomplete structure was created.
6495
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006496- Issue #3339: dummy_thread.acquire() should not return None.

6499
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006500- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006501
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006502- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6503 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006504 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006505 content-length. The problem had been corrected in the 2.4 branch, but never
6506 merged into trunk.
6507
Georg Brandle78fbcc2008-07-05 10:13:36 +00006508- Issue #2663: add filtering capability to shutil.copytree().

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006912- On MacOS X it is now possible to install the framework in 64-bit
6913 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006914 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006915
6916 This is controlled by the configure argument ``--with-universal-archs``:
6917
6918 - ``--with-universal-archs=all``: install 4-way universal
6919
6920 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6921
6922 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6923
6924 This option should be used in combination with ``--enable-universalsdk=``.
6925
6926 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00006976- Issue #1631171: Re-implement the 'warnings' module in C (the
6977 original Python code has been kept as backup). This will allow for
6978 using the 'warning's machinery in such places as the parser where
6979 use of pure Python code is not possible. Both the ``showarning()``
6980 and ``formatwarning()`` gain an optional 'line' argument which is
6981 not called by default for backwards-compatibility reasons. Setting
6982 ``warnings.showwarning()`` to an implementation that lacks support
6983 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007008- The getpass module has been improved on Unix. It now uses /dev/tty
7009 by default and uses stderr instead of stdout. A GetPassWarning is
7010 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007046- Issue #2550: The approach used by client/server code for obtaining
7047 ports to listen on in network-oriented tests has been refined in an
7048 effort to facilitate running multiple instances of the entire
7049 regression test suite in parallel without issue.
7050 test_support.bind_port() has been fixed such that it will always
7051 return a unique port -- which wasn't always the case with the
7052 previous implementation, especially if socket options had been set
7053 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7054 new implementation of bind_port() will actually raise an exception
7055 if it is passed an AF_INET/SOCK_STREAM socket with either the
7056 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7057 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7058 the socket it's been passed. This currently only applies to
7059 Windows. This option prevents any other sockets from binding to the
7060 host/port we've bound to, thus removing the possibility of the
7061 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7062 when a second SOCK_STREAM socket binds and accepts to a host/port
7063 that's already been bound by another socket. The optional preferred
7064 port parameter to bind_port() has been removed. Under no
7065 circumstances should tests be hard coding ports!
7066
7067 test_support.find_unused_port() has also been introduced, which will
7068 pass a temporary socket object to bind_port() in order to obtain an
7069 unused port. The temporary socket object is then closed and
7070 deleted, and the port is returned. This method should only be used
7071 for obtaining an unused port in order to pass to an external program
7072 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7073 a parameter to a server-oriented class that doesn't give you direct
7074 access to the underlying socket used.
7075
7076 Finally, test_support.HOST has been introduced, which should be used
7077 for the host argument of any relevant socket calls (i.e. bind and
7078 connect).

7353-----------------
7354
Fred Drakea8ee94b2008-03-01 02:45:07 +00007355- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007356 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007357
Georg Brandlad61bc82008-02-23 15:11:18 +00007358- Issue #2067: file.__exit__() now calls subclasses' close() method.
7359
7360- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007361
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007362- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007363 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007364
Eric Smitha73fbe72008-02-23 03:09:44 +00007365- Added the future_builtins module, which contains hex() and oct().
7366 These are the PEP 3127 version of these functions, designed to be
7367 compatible with the hex() and oct() builtins from Python 3.0. They
7368 differ slightly in their output formats from the existing, unchanged
7369 Python 2.6 builtins. The expected usage of the future_builtins
7370 module is:
7371 from future_builtins import hex, oct
7372
Eric Smith7ef40bf2008-02-20 23:34:22 +00007373- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7374 exponents for exponents with absolute value < 100. Follows C99
7375 standard. This is a change on Windows, which would use 3 digits.
7376 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7377 so that any alterations it does to the resulting string will be
7378 available in stringlib/formatter.h (for float.__format__).
7379
Eric Smith5a3c1352008-02-19 13:21:56 +00007380- Implemented PEP 3101, Advanced String Formatting. This adds a new
7381 builtin format(); a format() method for str and unicode; a
7382 __format__() method to object, str, unicode, int, long, float, and
7383 datetime; the class string.Formatter; and the C API
7384 PyObject_Format().
7385
Georg Brandl3ee81df2008-05-17 18:14:43 +00007386- Fixed several potential crashes, all caused by specially crafted
7387 __del__ methods exploiting objects in temporarily inconsistent
7388 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007389
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007390- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007391 prevent a possible crash: an Abstract Base Class would try to access
7392 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007393
Georg Brandl3ee81df2008-05-17 18:14:43 +00007394- Fixed repr() and str() of complex numbers with infinity or nan as
7395 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007396
Georg Brandl3ee81df2008-05-17 18:14:43 +00007397- Clear all free lists during a gc.collect() of the highest generation
7398 in order to allow pymalloc to free more arenas. Python may give back
7399 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007400
Georg Brandl3ee81df2008-05-17 18:14:43 +00007401- Issue #2045: Fix an infinite recursion triggered when printing a
7402 subclass of collections.defaultdict, if its default_factory is set
7403 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007404
Christian Heimesf75dbef2008-02-08 00:11:31 +00007405- Fixed a minor memory leak in dictobject.c. The content of the free
7406 list was not freed on interpreter shutdown.
7407
Georg Brandl21e99f42010-03-07 15:23:59 +00007408- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007409 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007410
Georg Brandl3ee81df2008-05-17 18:14:43 +00007411- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7412 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007413 to compact the internal free lists of pre-allocted ints and floats.
7414
Georg Brandl3ee81df2008-05-17 18:14:43 +00007415- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7416 calls. Python expected the return type int but the fork familie
7417 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007418
Georg Brandl3ee81df2008-05-17 18:14:43 +00007419- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7420 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007421
Georg Brandl3ee81df2008-05-17 18:14:43 +00007422- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7423 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007424
Georg Brandl3ee81df2008-05-17 18:14:43 +00007425- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7426 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007427
Georg Brandl3ee81df2008-05-17 18:14:43 +00007428- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7429 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007430
Georg Brandl3ee81df2008-05-17 18:14:43 +00007431- Patch #1473257: generator objects gain a gi_code attribute. This is
7432 the same object as the func_code attribute of the function that
7433 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007434
Georg Brandl3ee81df2008-05-17 18:14:43 +00007435- Issue #1920: "while 0" statements were completely removed by the
7436 compiler, even in the presence of an "else" clause, which is
7437 supposed to be run when the condition is false. Now the compiler
7438 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007439
Guido van Rossumeead05f2008-01-24 18:21:02 +00007440- A few crashers fixed: weakref_in_del.py (issue #1377858);
7441 loosing_dict_ref.py (issue #1303614, test67.py);
7442 borrowed_ref_[34].py (not in tracker).
7443
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007444- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007445 suppressed while an extension is loaded by calling SetErrorMode in
7446 dynload_win.c. The error is still reported properly.
7447
Georg Brandl3ee81df2008-05-17 18:14:43 +00007448- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007449 several extension methods and modules do not work without unicode
7450 support.
7451
Georg Brandl26543b12008-01-21 18:36:51 +00007452- Issue #1882: when compiling code from a string, encoding cookies in the
7453 second line of code were not always recognized correctly.
7454
Georg Brandl14404b62008-01-19 19:27:05 +00007455- Issue #1679: "0x" was taken as a valid integer literal.
7456
Georg Brandl6caad7d2008-01-26 14:19:22 +00007457- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007458 added.
7459
Christian Heimesc94e2b52008-01-14 04:13:37 +00007460- sys.float_info / PyFloat_GetInfo: The floating point information
7461 object was converted from a dict to a specialized structseq object.
7462
Georg Brandl3ee81df2008-05-17 18:14:43 +00007463- Patch #1816: Added sys.flags structseq. It exposes the status of
7464 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007465
Georg Brandl3ee81df2008-05-17 18:14:43 +00007466- Objects/structseq.c: Implemented new structseq representation. The
7467 patch makes structseqs (e.g. the return value of os.stat) more
7468 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007469
Georg Brandl3ee81df2008-05-17 18:14:43 +00007470- Patch #1700288: added a type attribute cache that caches method
7471 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007472
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007473- Bug #1776: __import__() no longer accepts filenames on any platform.
7474 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007475
Georg Brandlaed6c662008-01-07 17:25:53 +00007476- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7477
Georg Brandl3ee81df2008-05-17 18:14:43 +00007478- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7479 envvar and sys.dont_write_bytecode attribute. All these can be set
7480 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007481
Georg Brandl3ee81df2008-05-17 18:14:43 +00007482- Improve some exception messages when Windows fails to load an
7483 extension module. Now we get for example '%1 is not a valid Win32
7484 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007485
Georg Brandl3ee81df2008-05-17 18:14:43 +00007486- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007488- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7489 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007490
Christian Heimes0a8143f2007-12-18 23:22:54 +00007491- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007492 and INF. float("nan"), float("inf") and float("-inf") now work on
7493 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007494
Georg Brandl3ee81df2008-05-17 18:14:43 +00007495- Compiler now generates simpler and faster code for dictionary
7496 literals. The oparg for BUILD_MAP now indicates an estimated
7497 dictionary size. There is a new opcode, STORE_MAP, for adding
7498 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007499
Georg Brandl3ee81df2008-05-17 18:14:43 +00007500- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007505- Issue #1538: Avoid copying string in split/rsplit if the split char
7506 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007507
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007508- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007509 SystemError.
7510
Nick Coghlanef01d822007-12-03 12:55:17 +00007511- PEP 366: Allow explicit relative imports when executing modules
7512 inside packages with the -m switch via a new module level
7513 __package__ attribute.
7514
Georg Brandl3ee81df2008-05-17 18:14:43 +00007515- Issue #1402: Fix a crash on exit, when another thread is still
7516 running, and if the deallocation of its frames somehow calls the
7517 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007518
Christian Heimes28104c52007-11-27 23:16:44 +00007519- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
7520
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00007521- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007522 attribute of an empty cell object.
7523
Georg Brandl3ee81df2008-05-17 18:14:43 +00007524- Issue #1460: The utf-7 incremental decoder did not accept truncated
7525 input. It now correctly saves its state between chunks of data.

7528 file can now be directly executed by passing their name to the
7529 interpreter. The directory/zipfile is automatically inserted as the
7530 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007531
Georg Brandl3ee81df2008-05-17 18:14:43 +00007532- Issue #1265: Fix a problem with sys.settrace, if the tracing
7533 function uses a generator expression when at the same time the
7534 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007535
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007536- sets and frozensets now have an isdisjoint() method.
7537
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007538- optimize the performance of builtin.sum().
7539
Neal Norwitz44f326e2007-10-05 05:29:17 +00007540- Fix warnings found by the new version of the Coverity checker.
7541
Georg Brandl21e99f42010-03-07 15:23:59 +00007542- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007543 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7544 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007545
Georg Brandl3ee81df2008-05-17 18:14:43 +00007546- Issue #1686386: Tuple's tp_repr did not take into account the
7547 possibility of having a self-referential tuple, which is possible
7548 from C code. Nor did object's tp_str consider that a type's tp_str
7549 could do something that could lead to an inifinite recursion.
7550 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7551 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007552
Georg Brandl3ee81df2008-05-17 18:14:43 +00007553- Issue #1164: It was possible to trigger deadlock when using the
7554 'print' statement to write to a file since the GIL was not released
7555 as needed. Now PyObject_Print() does the right thing along with
7556 various tp_print implementations of the built-in types and those in
7557 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007558
Georg Brandl3ee81df2008-05-17 18:14:43 +00007559- Issue #1147: Exceptions were directly allowing string exceptions in
7560 their throw() method even though string exceptions no longer
7561 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007562
Georg Brandl3ee81df2008-05-17 18:14:43 +00007563- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00007566- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007567 PyObject_Call() never calling back out to Python code to trigger
7568 recursion depth updates/checks. Required the creation of a static
7569 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007587 __*__ attributes. (Some already existed, e.g., __doc__ and
7588 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007589
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007590- Add -3 option to the interpreter to warn about features that are

7598 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007599
Brett Cannon229cee22007-05-05 01:34:02 +00007600- Deprecate BaseException.message as per PEP 352.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007606 setting a plain string, ie don't expand to single letter identifiers.
7607
Raymond Hettinger13936692007-04-11 18:40:58 +00007608- Request #1191699: Slices can now be pickled.

7618
Guido van Rossum143b5642007-03-23 04:58:42 +00007619- Bug #1683368: The object.__init__() and object.__new__() methods are
7620 now stricter in rejecting excess arguments. The only time when
7621 either allows excess arguments is when it is not overridden and the
7622 other one is. For backwards compatibility, when both are
7623 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007624 warning later). Also, type.__init__() insists on the same signature
7625 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007626
Georg Brandl3ee81df2008-05-17 18:14:43 +00007627- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7628 object to complex using its __complex__() method before falling back
7629 to the __float__() method. Therefore, the functions in the cmath
7630 module now can operate on objects that define a __complex__()
7631 method.

7648
Georg Brandl7b9c5552007-03-12 14:30:05 +00007649- Bug #1678647: write a newline after printing an exception in any
7650 case, even when converting the value to a string failed.
7651
Georg Brandl871f1bc2007-03-12 13:17:36 +00007652- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007653 its argument, if it exists. If not, it will work like before. This
7654 allows customizing the output of dir() in the presence of a
7655 __getattr__().

7665 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007666
Georg Brandlaa2321b2007-03-07 00:40:28 +00007667- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007668 makes the filenames the warning module prints much more sensible
7669 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007670

Georg Brandl0fca97a2007-03-05 22:28:08 +00007682- Patch #1674228: when assigning a slice (old-style), check for the
7683 sq_ass_slice instead of the sq_slice slot.
7684
Georg Brandl3ee81df2008-05-17 18:14:43 +00007685- When printing an unraisable error, don't print exceptions. before

8313 accepted in TestSuite.addTest(). This should cause no
8314 incompatibility since it never made sense with ordinary subclasses
8315 -- the failure just occurred later, with a more cumbersome
8316 exception.

8600 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008601
Georg Brandl3ee81df2008-05-17 18:14:43 +00008602- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008603 that the SMTP.starttls() caller no longer needs to call ehlo()
8604 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008605 does not claim to support starttls. Adds the
8606 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00008705 time so that opening a database previously created with the DB_DUP
8706 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8707 opens. Specifically: dictionary assignment to a DB object will
8708 replace all values for a given key when the database allows
8709 duplicate values. DB users should use DB.put(k, v) when they want
8710 to store duplicates; not DB[k] = v.

8717 characters with ASCII value less than 32. Also, it correctly quotes
8718 dots only if they occur on a single line, as opposed to the previous
8719 behavior of quoting dots if they are the second character of any
8720 line.

9043-----
9044
Georg Brandl3ee81df2008-05-17 18:14:43 +00009045- Unified naming convention for free lists and their limits. All free
9046 lists in Object/ are named ``free_list``, the counter ``numfree``
9047 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9048 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009049
Georg Brandl3ee81df2008-05-17 18:14:43 +00009050- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9051 to ``PyTuple_SetItem``, it can be used to populate a brand new
9052 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009053
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009054- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009055
Georg Brandl3ee81df2008-05-17 18:14:43 +00009056- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9057 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9058 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009059
9060- Patch #1720595: add T_BOOL to the range of structmember types.
9061
9062- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9063 ``PyFloat_GetInfo()`` to the float API.
9064
Georg Brandl3ee81df2008-05-17 18:14:43 +00009065- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9066 of w# format code incorrectly truncated the length to an int, even
9067 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9068 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009069
Georg Brandl3ee81df2008-05-17 18:14:43 +00009070- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9071 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009072
Georg Brandl3ee81df2008-05-17 18:14:43 +00009073- PEP 3123: Provide forward compatibility with Python 3.0, while
9074 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9075 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009076
Georg Brandl3ee81df2008-05-17 18:14:43 +00009077- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9078 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009079
9080- Patch #1733960: Allow T_LONGLONG to accept ints.
9081
9082- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9083
Christian Heimes000a0742008-01-03 22:16:32 +00009084- Added a new API function ``PyImport_ImportModuleNoBlock``.
9085
Georg Brandl6caad7d2008-01-26 14:19:22 +00009086- Bug #1637022: Prefix AST symbols with _Py_.
9087
9088- Fix some leftovers from the conversion from int to Py_ssize_t
9089 (relevant to strings and sequences of more than 2**31 items).
9090
9091- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9092 outside of pystate.c and should not be necessary.
9093
Georg Brandl3ee81df2008-05-17 18:14:43 +00009094- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9095 absolute imports. In earlier versions they might have used relative
9096 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009097
Georg Brandl3ee81df2008-05-17 18:14:43 +00009098- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9099 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009100
Georg Brandl3ee81df2008-05-17 18:14:43 +00009101- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
9102 macro so it can be used as an expression.

9107
Georg Brandl3ee81df2008-05-17 18:14:43 +00009108- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9109 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9110 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9111 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009112
Georg Brandl3ee81df2008-05-17 18:14:43 +00009113- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
9114 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009126- Removed the macfs module. It had been deprecated since Python 2.5.
9127 This lead to the deprecation of macostools.touched() as it relied
9128 solely on macfs and was a no-op under OS X.
