Ezio Melottiab2eb0e2010-06-05 19:21:32 +000095- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
96 start byte and the continuation byte(s) are now considered invalid, instead
97 of the number of bytes specified by the start byte.
98 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
99 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
100 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
101 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000109- Issue #8748: Fix two issues with comparisons between complex and integer
110 objects. (1) The comparison could incorrectly return True in some cases
111 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
112 (2) The comparison raised an OverflowError for large integers, leading
113 to unpredictable exceptions when combining integers and complex objects
114 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +0000116- Issue #5211: Implicit coercion for the complex type is now completely
117 removed. (Coercion for arithmetic operations was already removed in 2.7
118 alpha 4, but coercion for rich comparisons was accidentally left in.)

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

Georg Brandlfee0f442010-05-22 21:26:21 +0000551- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
552 InvalidOperation instead of returning False. (Comparisons involving a quiet
553 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
554 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +0000556- Issue #2531: Comparison operations between floats and Decimal instances now
557 return a result based on the numeric values of the operands; previously they
558 returned an arbitrary result based on the relative ordering of id(float) and
559 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000561- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000562 argument `-` which tells it to read files to compile from stdin. Each line is
563 read on demand and the named file is compiled immediately. (Original patch by
564 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000573- Comparisons using one of <, <=, >, >= between a complex instance and a
574 Fractions instance now raise TypeError instead of returning True/False. This
575 makes Fraction <=> complex comparisons consistent with int <=> complex, float
576 <=> complex, and complex <=> complex comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +0000683 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
684 inconsistent: __int__ was used for some integer codes but not for others, and
685 the set of integer codes for which it was used differed between native packing
686 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000984 file position when calling `truncate()`. It would previously change the file
985 position to the given argument, which goes against the tradition of

989 class used to represent files stored inside an archive. The new
990 implementation is significantly faster and can be wrapped in a

992 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1082
Georg Brandlba83f822010-03-14 09:50:54 +00001083- The ``__complex__()`` method is now looked up on the class of instances to
1084 make it consistent with other special methods.

1088
Mark Dickinson1b34d252010-01-01 17:27:30 +00001089- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001090 DeprecationWarning when passed a float argument where an integer was expected.
1091 These functions and methods now raise TypeError instead. The majority of the
1092 effects of this change are in the extension modules, but some core functions
1093 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1094 and many unicode/str methods.

1109 least on IEEE 754 platforms), and in particular does not depend on the
1110 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001256- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1257 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001258
Georg Brandlba83f822010-03-14 09:50:54 +00001259- Issue #3382: 'F' formatting for float and complex now convert the result to
1260 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1261 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001262
Georg Brandlba83f822010-03-14 09:50:54 +00001263- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1264 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001265
Georg Brandlba83f822010-03-14 09:50:54 +00001266- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1267 1e-100 used to raise OverflowError, but now gives the requested 120
1268 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001269
Georg Brandlba83f822010-03-14 09:50:54 +00001270- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00001271
Georg Brandlba83f822010-03-14 09:50:54 +00001272- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00001273
Georg Brandlba83f822010-03-14 09:50:54 +00001274- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
1275 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001276
Georg Brandlba83f822010-03-14 09:50:54 +00001277- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1278 decimal string that's guaranteed to round back to x under correct rounding
1279 (with round-half-to-even rounding mode). Previously it gave a string based on
1280 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1281 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1282 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001283
Georg Brandlba83f822010-03-14 09:50:54 +00001284- Issue #7117: On almost all platforms: float-to-string and string-to-float
1285 conversions within Python are now correctly rounded. Places these conversions
1286 occur include: str for floats and complex numbers; the float and complex
1287 constructors; old-style and new-style numeric formatting; serialization and
1288 deserialization of floats and complex numbers using marshal, pickle and json;
1289 parsing of float and imaginary literals in Python code; Decimal-to-float
1290 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001291
Georg Brandlba83f822010-03-14 09:50:54 +00001292 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1293 providing correctly-rounded strtod and dtoa C functions. This code is
1294 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1295 the C compiler. There may be a small number of platforms on which correct
1296 operation of this code cannot be guaranteed, so the code is not used: notably,
1297 this applies to platforms where the C double format is not IEEE 754 binary64,
1298 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1299 and Python's configure script is unable to determine how to change the FPU
1300 precision. On these platforms conversions use the platform strtod and dtoa,
1301 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001302
Georg Brandlba83f822010-03-14 09:50:54 +00001303- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1304 uses the correctly-rounded string <-> float conversions described above (when
1305 available), and so produces correctly rounded results that will display nicely
1306 under the float repr. There are two related small changes: (1) round now
1307 accepts any class with an ``__index__()`` method for its second argument (but
1308 no longer accepts floats for the second argument), and (2) an excessively
1309 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1310 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +00001311
Philip Jenveyfab8be22009-11-17 02:42:26 +00001312- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
1313
Georg Brandlba83f822010-03-14 09:50:54 +00001314- Fix several issues with ``compile()``. The input can now contain Windows and
1315 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00001316
Georg Brandlba83f822010-03-14 09:50:54 +00001317- Remove length limitation when constructing a complex number from a unicode
1318 string.
Mark Dickinsonc04c7c52009-10-26 22:28:14 +00001319
Georg Brandlba83f822010-03-14 09:50:54 +00001320- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
1321 during the formation of an output tuple.
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +00001322
Mark Dickinson8d87dc02009-10-25 20:39:06 +00001323- Issue #1087418: Boost performance of bitwise operations for longs.
1324
Georg Brandlba83f822010-03-14 09:50:54 +00001325- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
1326 which fixes the problem of some exceptions being thrown at shutdown when the
1327 interpreter is killed. Patch by Adam Olsen.
Antoine Pitrouefb60c02009-10-20 21:29:37 +00001328
Georg Brandlba83f822010-03-14 09:50:54 +00001329- Issue #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``,
1330 and note that they are unsafe and deprecated.
Eric Smithc12781a2009-10-19 14:38:14 +00001331
Georg Brandlba83f822010-03-14 09:50:54 +00001332- Issue #7120: logging: Remove import of multiprocessing which is causing crash
1333 in GAE.
Vinay Sajip03d5c342009-10-16 14:06:44 +00001334
Georg Brandlba83f822010-03-14 09:50:54 +00001335- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
1336 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +00001337
Georg Brandlba83f822010-03-14 09:50:54 +00001338- Issue #1754094: Improve the stack depth calculation in the compiler. There
1339 should be no other effect than a small decrease in memory use. Patch by
1340 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +00001341
Georg Brandlba83f822010-03-14 09:50:54 +00001342- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
1343 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +00001344
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00001345- Issue #1571184: The Unicode database contains properties for more characters.
1346 The tables for code points representing numeric values, white spaces or line
1347 breaks are now generated from the official Unicode Character Database files,
1348 and include information from the Unihan.txt file.
1349

1354 running through the shell. Patch by Jean-Paul Calderone and Jani Hakala.
Philip Jenvey8b902042009-09-29 19:10:15 +00001355
Georg Brandlba83f822010-03-14 09:50:54 +00001356- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of

Georg Brandlba83f822010-03-14 09:50:54 +00001404- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
1405 build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
1406 of stdint.h on that platform.
Mark Dickinson2f865b92009-06-30 15:32:30 +00001407

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001451- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00001452
Georg Brandlba83f822010-03-14 09:50:54 +00001453 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1454 (2) parsing of strings representing infinities and nans was locale aware; and
1455 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00001456
Georg Brandlba83f822010-03-14 09:50:54 +00001457- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1458 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1459 but with at least one decimal point and with a default precision
1460 of 12. Previously, the behavior the same but with a default precision of 6.
1461 This more closely matches ``str()``, and reduces surprises when adding
1462 alignment flags to the empty presentation type. This also affects the new
1463 complex.__format__ in the same way.
1464
1465- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1466 classtype's, even if it was None. property now inserts the __doc__ into the
1467 subclass instance __dict__.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001715- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1716 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

1725 gives improved memory leak detection when running under Valgrind, while taking
1726 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00002949 leak-chasing test runs give sensible results. The previous method of reaping
2950 threads could return successfully while some Thread objects were still

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003093- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

3095 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3096 ``printf`` function, whereas PyString_FromFormat has an independent
3097 implementation and uses "%zd" on all platforms for size_t values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003118- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003119 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3120 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3121 when given a tuple of classes as second argument, were looking up
3122 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3123 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003262What's New in Python 2.6 beta 3?
3263================================
3264
Barry Warsaw07a4a382008-08-21 01:15:08 +00003265*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003266
3267Core and Builtins
3268-----------------
3269
Guido van Rossumf8402962008-08-20 15:01:50 +00003270- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3271 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3272 extensions do not automatically benefit from the class attribute
3273 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3274 to their tp_flags field if they care. This is a backwards
3275 compatibility feature; in 3.0, all types will use the cache by
3276 default.
3277
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003278- Keyword arguments can now follow starred arguments. (``f(a, *args,
3279 keyword=23)`` is now valid syntax.)
3280
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003281- ctypes function pointers that are COM methods have a boolean True
3282 value again.
3283
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003284- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3285 by denying s# to parse objects that have a releasebuffer procedure,
3286 and introducing s*.
3287
Georg Brandl1e13ea92008-08-11 09:07:59 +00003288- Issue #3537: Fix an assertion failure when an empty but presized dict
3289 object was stored in the freelist.
3290
Mark Dickinsonb6467572008-08-04 21:30:09 +00003291- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3292 ValueError consistently across platforms.
3293
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003294- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3295 (64bit Unix, for example), unichr() would truncate its argument and return
3296 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3297
Neal Norwitze7d8be82008-07-31 17:17:14 +00003298- Apply security patches from Apple.
3299
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003300- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3301 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3302
Antoine Pitrou92f82162008-07-25 22:22:08 +00003303- Issue #1819: function calls with several named parameters are now on
3304 average 35% faster (as measured by pybench).
3305
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003306- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3307 the python debugger steps into a class statement: the free variables (local
3308 variables defined in an outer scope) would be deleted from the outer scope.
3309
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003310- Issue #2620: Overflow checking when allocating or reallocating memory
3311 was not always being done properly in some python types and extension
3312 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3313 all been updated to perform better checks and places in the code that
3314 would previously leak memory on the error path when such an allocation
3315 failed have been fixed.

3319
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003320- Issue #3612: Added some missing basic types in ctypes.wintypes.
3321
Benjamin Petersone977ad42008-08-20 01:42:01 +00003322- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3323 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3324
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003325- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3326 version reported by these tools does not necessarily follow the python
3327 version numbering scheme, so the module is less strict when parsing it.
3328
Nick Coghlanf70385a2008-08-18 12:42:46 +00003329- Issue #2235: Added Py3k warnings for types which will become unhashable
3330 under the stricter __hash__ inheritance rules in 3.0. Several types
3331 which did not meet the rules for hash invariants and were already
3332 unhashable in 3.0 have now been explicitly flagged as unhashable in
3333 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3334 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3335
Brett Cannon88f801d2008-08-18 00:46:22 +00003336- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3337 imported into the module but exposed as part of the module's API.
3338
Brett Cannon7b96f072008-08-18 00:41:11 +00003339- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3340
Brett Cannon46225e72008-08-18 00:36:52 +00003341- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3342
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003343- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3344
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003345- Issue #3575: Incremental decoder's decode function now takes bytearray
3346 by using 's*' instead of 't#'.
3347
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003348- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003349 fails unicode conversion on 2nd parameter. (windows only)
3350
Facundo Batista94f243a2008-08-17 03:38:39 +00003351- Issue 2464. urllib2 now supports a malformation in the URL received
3352 in a redirect.
3353
Brett Cannonabe423e2008-08-16 21:47:07 +00003354- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003355 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003356
Facundo Batistaeb90b782008-08-16 14:44:07 +00003357- Issue #2776: fixed small issue when handling an URL with double slash
3358 after a 302 response in the case of not going through a proxy.
3359
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003360- Issue #2676: in the email package, content-type parsing was hanging on
3361 pathological input because of quadratic or exponential behaviour of a
3362 regular expression.
3363
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003364- Issue #3476: binary buffered reading through the new "io" library is now
3365 thread-safe.
3366
Brett Cannonbf3157b2008-08-14 05:00:03 +00003367- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3368 since mimetools itself is deprecated. Because modules are cached, all
3369 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3370
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003371- Issue #3134: shutil referenced undefined WindowsError symbol.
3372
Robert Schuppenies14646332008-08-10 11:01:53 +00003373- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3374 menu entries were not deleted.
3375
Brett Cannon83e81842008-08-09 23:30:55 +00003376- Copied the implementation of reduce() to _functools.reduce() to have a
3377 version that did not raise a DeprecationWarning under -3.
3378
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003379- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3380 a MemoryError rather than silently stop the iteration.
3381
Guido van Rossum59ce9012008-08-09 14:55:34 +00003382- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3383 to _sre.compile() will now be rejected. This should not affect anybody
3384 since the re.compile() function never generates invalid re-bytecode.
3385
Skip Montanaroa032bf42008-08-08 22:52:51 +00003386- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3387 upon first access it can be automatically initialized from the csv file if
3388 it wasn't initialized during instantiation.
3389
Brett Cannon3aa2a492008-08-06 22:28:09 +00003390- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3391 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00003405 asking for a specific length. This problem only affected files opened
3406 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003407

3432 file name rather than a ZipInfo instance, so files are extracted with
3433 mode 0600 rather than 000 under Unix.
3434
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003435- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3448 interaction with the tp_hash slot (added in 2.6b2) are now documented
3449
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003450- Issue #643841: The language reference now provides more detailed
3451 coverage of the lookup process for special methods. The disclaimers
3452 regarding lack of coverage of new-style classes have also been

3458
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003459*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003461Core and Builtins
3462-----------------
3463
Georg Brandl3e483f62008-07-16 22:57:41 +00003464- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3465 its methods now allow for items objects that can be converted to
3466 an integer using operator.index().
3467
Mark Dickinson64b7e502008-07-16 09:40:03 +00003468- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3469 produced a ValueError instead of giving the correct float.
3470
Eric Smitha5fa5a22008-07-16 00:11:49 +00003471- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3472 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3473
Mark Dickinson7103aa42008-07-15 19:08:33 +00003474- Issue #3008: the float type has a new instance method 'float.hex'
3475 and a new class method 'float.fromhex' to convert floating-point
3476 numbers to and from hexadecimal strings, respectively.
3477
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003478- Issue #2235: __hash__ is once again inherited by default. To allow
3479 collections.Hashable to remain meaningful in the presence of the
3480 default hash implementation (object.__hash__), it is now possible
3481 to explicit block inheritance of hash by setting __hash__=None at
3482 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3483 level.
3484
Nick Coghlanb028f502008-07-13 14:52:36 +00003485- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3486 the parent module cannot be found while performing an absolute import.
3487 This means that an incorrectly defined __package__ attribute will
3488 now only prevent relative imports in that module rather than causing
3489 all imports from that module to fail.
3490
Nick Coghlan14ff9942008-07-08 14:21:42 +00003491- Issue #2517: Allow unicode messages in Exceptions again by correctly
3492 bypassing the instance dictionary when looking up __unicode__ on
3493 new-style classes.

3496 set to a custom object whose write() method happens to install
3497 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003499- Issue #3088: Corrected a race condition in classes derived from
3500 threading.local: the first member set by a thread could be saved in
3501 another thread's dictionary.
3502
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003503- Issue #3004: Minor change to slice.indices(): the start and stop
3504 arguments are now treated identically, making the behaviour easier
3505 to describe and understand. For example, slice(None, -10,
3506 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3507 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3508 10, -1).
3509
Georg Brandl278fc502008-07-19 12:46:12 +00003510- Issue #3219: Calling a function with repeated keyword arguments,
3511 f(a=2, a=23), would not cause a syntax error. This was a regression
3512 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003513
Georg Brandl278fc502008-07-19 12:46:12 +00003514- Issue #2862: Make int and float freelist management consistent with
3515 other freelists. Changes their CompactFreeList apis into
3516 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003521- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3522 api functions without holding the GIL, which could lead to a fatal
3523 error when they failed.
3524
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003525- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003550- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3551 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003552 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003553 content-length. The problem had been corrected in the 2.4 branch, but never
3554 merged into trunk.
3555
Georg Brandle78fbcc2008-07-05 10:13:36 +00003556- Issue #2663: add filtering capability to shutil.copytree().

Facundo Batista66c52772008-07-02 16:52:55 +00003568
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003569- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3570 handling is now the same as that of other special attributes like __name__).
3571
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003572- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003960- On MacOS X it is now possible to install the framework in 64-bit
3961 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003962 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003963
3964 This is controlled by the configure argument ``--with-universal-archs``:
3965
3966 - ``--with-universal-archs=all``: install 4-way universal
3967
3968 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3969
3970 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3971
3972 This option should be used in combination with ``--enable-universalsdk=``.
3973
3974 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3979
Georg Brandl74a1dea2008-05-28 11:21:39 +00003980- Add ``PyType_Modified()`` as a public API to clear the type cache.
3981
3982- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003983
3984- The PyString functions have been renamed to PyBytes. A batch of
3985 defines were added so that the linker still sees the original
3986 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004024- Issue #1631171: Re-implement the 'warnings' module in C (the
4025 original Python code has been kept as backup). This will allow for
4026 using the 'warning's machinery in such places as the parser where
4027 use of pure Python code is not possible. Both the ``showarning()``
4028 and ``formatwarning()`` gain an optional 'line' argument which is
4029 not called by default for backwards-compatibility reasons. Setting
4030 ``warnings.showwarning()`` to an implementation that lacks support
4031 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004056- The getpass module has been improved on Unix. It now uses /dev/tty
4057 by default and uses stderr instead of stdout. A GetPassWarning is
4058 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004073- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004074 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004094- Issue #2550: The approach used by client/server code for obtaining
4095 ports to listen on in network-oriented tests has been refined in an
4096 effort to facilitate running multiple instances of the entire
4097 regression test suite in parallel without issue.
4098 test_support.bind_port() has been fixed such that it will always
4099 return a unique port -- which wasn't always the case with the
4100 previous implementation, especially if socket options had been set
4101 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4102 new implementation of bind_port() will actually raise an exception
4103 if it is passed an AF_INET/SOCK_STREAM socket with either the
4104 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4105 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4106 the socket it's been passed. This currently only applies to
4107 Windows. This option prevents any other sockets from binding to the
4108 host/port we've bound to, thus removing the possibility of the
4109 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4110 when a second SOCK_STREAM socket binds and accepts to a host/port
4111 that's already been bound by another socket. The optional preferred
4112 port parameter to bind_port() has been removed. Under no
4113 circumstances should tests be hard coding ports!
4114
4115 test_support.find_unused_port() has also been introduced, which will
4116 pass a temporary socket object to bind_port() in order to obtain an
4117 unused port. The temporary socket object is then closed and
4118 deleted, and the port is returned. This method should only be used
4119 for obtaining an unused port in order to pass to an external program
4120 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4121 a parameter to a server-oriented class that doesn't give you direct
4122 access to the underlying socket used.
4123
4124 Finally, test_support.HOST has been introduced, which should be used
4125 for the host argument of any relevant socket calls (i.e. bind and
4126 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004127
4128 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004129 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004130 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4131 test_asynchat and test_socket_ssl.
4132
Georg Brandl3ee81df2008-05-17 18:14:43 +00004133 It is now possible for multiple instances of the regression test
4134 suite to run in parallel without issue.

4401-----------------
4402
Fred Drakea8ee94b2008-03-01 02:45:07 +00004403- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004404 644. The mode is now inherited from the py file.

4407
4408- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004409
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004410- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004411 issue 215555 for a discussion.
4412
Eric Smitha73fbe72008-02-23 03:09:44 +00004413- Added the future_builtins module, which contains hex() and oct().
4414 These are the PEP 3127 version of these functions, designed to be
4415 compatible with the hex() and oct() builtins from Python 3.0. They
4416 differ slightly in their output formats from the existing, unchanged
4417 Python 2.6 builtins. The expected usage of the future_builtins
4418 module is:
4419 from future_builtins import hex, oct
4420
Eric Smith7ef40bf2008-02-20 23:34:22 +00004421- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4422 exponents for exponents with absolute value < 100. Follows C99
4423 standard. This is a change on Windows, which would use 3 digits.
4424 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4425 so that any alterations it does to the resulting string will be
4426 available in stringlib/formatter.h (for float.__format__).
4427
Eric Smith5a3c1352008-02-19 13:21:56 +00004428- Implemented PEP 3101, Advanced String Formatting. This adds a new
4429 builtin format(); a format() method for str and unicode; a
4430 __format__() method to object, str, unicode, int, long, float, and
4431 datetime; the class string.Formatter; and the C API
4432 PyObject_Format().
4433
Georg Brandl3ee81df2008-05-17 18:14:43 +00004434- Fixed several potential crashes, all caused by specially crafted
4435 __del__ methods exploiting objects in temporarily inconsistent
4436 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004437
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004438- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004439 prevent a possible crash: an Abstract Base Class would try to access
4440 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004441

Georg Brandl3ee81df2008-05-17 18:14:43 +00004445- Clear all free lists during a gc.collect() of the highest generation
4446 in order to allow pymalloc to free more arenas. Python may give back
4447 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004448
Georg Brandl3ee81df2008-05-17 18:14:43 +00004449- Issue #2045: Fix an infinite recursion triggered when printing a
4450 subclass of collections.defaultdict, if its default_factory is set
4451 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004452
Christian Heimesf75dbef2008-02-08 00:11:31 +00004453- Fixed a minor memory leak in dictobject.c. The content of the free
4454 list was not freed on interpreter shutdown.
4455
Georg Brandl21e99f42010-03-07 15:23:59 +00004456- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004457 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004458

4460 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004461 to compact the internal free lists of pre-allocted ints and floats.
4462
Georg Brandl3ee81df2008-05-17 18:14:43 +00004463- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4464 calls. Python expected the return type int but the fork familie
4465 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004466

4477 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004478
Georg Brandl3ee81df2008-05-17 18:14:43 +00004479- Patch #1473257: generator objects gain a gi_code attribute. This is
4480 the same object as the func_code attribute of the function that
4481 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004482
Georg Brandl3ee81df2008-05-17 18:14:43 +00004483- Issue #1920: "while 0" statements were completely removed by the
4484 compiler, even in the presence of an "else" clause, which is
4485 supposed to be run when the condition is false. Now the compiler
4486 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004487
Guido van Rossumeead05f2008-01-24 18:21:02 +00004488- A few crashers fixed: weakref_in_del.py (issue #1377858);
4489 loosing_dict_ref.py (issue #1303614, test67.py);
4490 borrowed_ref_[34].py (not in tracker).
4491
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004492- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004493 suppressed while an extension is loaded by calling SetErrorMode in
4494 dynload_win.c. The error is still reported properly.
4495
Georg Brandl3ee81df2008-05-17 18:14:43 +00004496- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004497 several extension methods and modules do not work without unicode
4498 support.
4499
Georg Brandl26543b12008-01-21 18:36:51 +00004500- Issue #1882: when compiling code from a string, encoding cookies in the
4501 second line of code were not always recognized correctly.
4502
Georg Brandl14404b62008-01-19 19:27:05 +00004503- Issue #1679: "0x" was taken as a valid integer literal.
4504
Georg Brandl6caad7d2008-01-26 14:19:22 +00004505- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004506 added.
4507
Christian Heimesc94e2b52008-01-14 04:13:37 +00004508- sys.float_info / PyFloat_GetInfo: The floating point information
4509 object was converted from a dict to a specialized structseq object.
4510
Georg Brandl3ee81df2008-05-17 18:14:43 +00004511- Patch #1816: Added sys.flags structseq. It exposes the status of
4512 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004513
Georg Brandl3ee81df2008-05-17 18:14:43 +00004514- Objects/structseq.c: Implemented new structseq representation. The
4515 patch makes structseqs (e.g. the return value of os.stat) more
4516 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004517
Georg Brandl3ee81df2008-05-17 18:14:43 +00004518- Patch #1700288: added a type attribute cache that caches method
4519 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004520
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004521- Bug #1776: __import__() no longer accepts filenames on any platform.
4522 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004523
Georg Brandlaed6c662008-01-07 17:25:53 +00004524- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4525
Georg Brandl3ee81df2008-05-17 18:14:43 +00004526- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4527 envvar and sys.dont_write_bytecode attribute. All these can be set
4528 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004529
Georg Brandl3ee81df2008-05-17 18:14:43 +00004530- Improve some exception messages when Windows fails to load an
4531 extension module. Now we get for example '%1 is not a valid Win32
4532 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004533
Georg Brandl3ee81df2008-05-17 18:14:43 +00004534- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004536- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4537 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004538
Christian Heimes0a8143f2007-12-18 23:22:54 +00004539- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004540 and INF. float("nan"), float("inf") and float("-inf") now work on
4541 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004542
Georg Brandl3ee81df2008-05-17 18:14:43 +00004543- Compiler now generates simpler and faster code for dictionary
4544 literals. The oparg for BUILD_MAP now indicates an estimated
4545 dictionary size. There is a new opcode, STORE_MAP, for adding
4546 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004547
Georg Brandl3ee81df2008-05-17 18:14:43 +00004548- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004553- Issue #1538: Avoid copying string in split/rsplit if the split char
4554 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004555
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004556- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004557 SystemError.
4558
Nick Coghlanef01d822007-12-03 12:55:17 +00004559- PEP 366: Allow explicit relative imports when executing modules
4560 inside packages with the -m switch via a new module level
4561 __package__ attribute.
4562
Georg Brandl3ee81df2008-05-17 18:14:43 +00004563- Issue #1402: Fix a crash on exit, when another thread is still
4564 running, and if the deallocation of its frames somehow calls the
4565 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004566

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004570 attribute of an empty cell object.
4571
Georg Brandl3ee81df2008-05-17 18:14:43 +00004572- Issue #1460: The utf-7 incremental decoder did not accept truncated
4573 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004574
Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- Patch #1739468: Directories and zipfiles containing a __main__.py
4576 file can now be directly executed by passing their name to the
4577 interpreter. The directory/zipfile is automatically inserted as the
4578 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004579
Georg Brandl3ee81df2008-05-17 18:14:43 +00004580- Issue #1265: Fix a problem with sys.settrace, if the tracing
4581 function uses a generator expression when at the same time the
4582 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004583
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004584- sets and frozensets now have an isdisjoint() method.
4585
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004586- optimize the performance of builtin.sum().
4587
Neal Norwitz44f326e2007-10-05 05:29:17 +00004588- Fix warnings found by the new version of the Coverity checker.
4589
Georg Brandl21e99f42010-03-07 15:23:59 +00004590- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004591 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4592 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004593
Georg Brandl3ee81df2008-05-17 18:14:43 +00004594- Issue #1686386: Tuple's tp_repr did not take into account the
4595 possibility of having a self-referential tuple, which is possible
4596 from C code. Nor did object's tp_str consider that a type's tp_str
4597 could do something that could lead to an inifinite recursion.
4598 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4599 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004600
Georg Brandl3ee81df2008-05-17 18:14:43 +00004601- Issue #1164: It was possible to trigger deadlock when using the
4602 'print' statement to write to a file since the GIL was not released
4603 as needed. Now PyObject_Print() does the right thing along with
4604 various tp_print implementations of the built-in types and those in
4605 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004606
Georg Brandl3ee81df2008-05-17 18:14:43 +00004607- Issue #1147: Exceptions were directly allowing string exceptions in
4608 their throw() method even though string exceptions no longer
4609 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004610
Georg Brandl3ee81df2008-05-17 18:14:43 +00004611- Issue #1096: Prevent a segfault from getting the repr of a very
4612 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004613
Brett Cannon1e534b52007-09-07 04:18:30 +00004614- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004615 PyObject_Call() never calling back out to Python code to trigger
4616 recursion depth updates/checks. Required the creation of a static
4617 RuntimeError instance in case normalizing an exception put the
4618 recursion check value past its limit. Fixes crashers
4619 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004620
Georg Brandl3ee81df2008-05-17 18:14:43 +00004621- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004634- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004635 __*__ attributes. (Some already existed, e.g., __doc__ and
4636 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004637
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004638- Add -3 option to the interpreter to warn about features that are
4639 deprecated and will be changed/removed in Python 3.0.
4640
Georg Brandl2134e752007-05-21 20:34:16 +00004641- Patch #1686487: you can now pass any mapping after '**' in function
4642 calls.
4643
Collin Winter62903052007-05-18 23:11:24 +00004644- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004645 "except E as target:". This is to provide forwards compatibility
4646 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004647
Brett Cannon229cee22007-05-05 01:34:02 +00004648- Deprecate BaseException.message as per PEP 352.
4649
Georg Brandl3ee81df2008-05-17 18:14:43 +00004650- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004651 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004652
Vinay Sajip8549ce32007-05-06 17:53:37 +00004653- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004654 setting a plain string, ie don't expand to single letter identifiers.
4655
Raymond Hettinger13936692007-04-11 18:40:58 +00004656- Request #1191699: Slices can now be pickled.
4657
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004658- Request #1193128: str.translate() now allows a None argument for
4659 translations that only remove characters without re-mapping the
4660 remaining characters.
4661
Georg Brandl5cb76c12007-03-21 09:00:39 +00004662- Patch #1682205: a TypeError while unpacking an iterable is no longer
4663 masked by a generic one with the message "unpack non-sequence".
4664
Neal Norwitzaa754b72007-03-21 06:39:48 +00004665- Remove unused file Python/fmod.c.
4666
Guido van Rossum143b5642007-03-23 04:58:42 +00004667- Bug #1683368: The object.__init__() and object.__new__() methods are
4668 now stricter in rejecting excess arguments. The only time when
4669 either allows excess arguments is when it is not overridden and the
4670 other one is. For backwards compatibility, when both are
4671 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004672 warning later). Also, type.__init__() insists on the same signature
4673 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004674
Georg Brandl3ee81df2008-05-17 18:14:43 +00004675- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4676 object to complex using its __complex__() method before falling back
4677 to the __float__() method. Therefore, the functions in the cmath
4678 module now can operate on objects that define a __complex__()
4679 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004680
Georg Brandl3ee81df2008-05-17 18:14:43 +00004681- Patch #1623563: allow __class__ assignment for classes with
4682 __slots__. The old and the new class are still required to have the
4683 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004684
Georg Brandl3ee81df2008-05-17 18:14:43 +00004685- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004688- Patch #1462488: Python no longer segfaults when
4689 ``object.__reduce_ex__()`` is called with an object that is faking
4690 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004691
Georg Brandl3ee81df2008-05-17 18:14:43 +00004692- Patch #1680015: Don't modify __slots__ tuple if it contains an

4696
Georg Brandl7b9c5552007-03-12 14:30:05 +00004697- Bug #1678647: write a newline after printing an exception in any
4698 case, even when converting the value to a string failed.
4699
Georg Brandl871f1bc2007-03-12 13:17:36 +00004700- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004701 its argument, if it exists. If not, it will work like before. This
4702 allows customizing the output of dir() in the presence of a
4703 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004704
Collin Winter276887b2007-03-12 16:11:39 +00004705- Patch #922167: Python no longer segfaults when faced with infinitely
4706 self-recursive reload() calls (as reported by bug #742342).
4707
Georg Brandl3ee81df2008-05-17 18:14:43 +00004708- Patch #1675981: remove unreachable code from ``type.__new__()``
4709 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004711- Patch #1491866: change the complex() constructor to allow
4712 parthensized forms. This means complex(repr(x)) now works instead of
4713 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004714

5224 ".cpp" too.
5225
Facundo Batistad918a652007-04-24 13:54:38 +00005226- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005227 the client's request was successfully received, understood, and
5228 accepted. Now in these cases no error is raised in urllib (issue
5229 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00005230

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005237- Added a timeout parameter to the constructor of other protocols
5238 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5239 work started with create_connection() and timeout in httplib, and
5240 closes patch #723312.
5241
Vinay Sajip8549ce32007-05-06 17:53:37 +00005242- Patch #1676823: Added create_connection() to socket.py, which may be
5243 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00005244 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00005245
Martin v. Löwis0af33882007-03-23 13:27:15 +00005246- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005253- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
5254 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00005255 directories.
5256

5266
Georg Brandlf66b6032007-03-14 08:27:52 +00005267- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005268 AttributeError instead of an IOError when the server's response
5269 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005270
Georg Brandl3ee81df2008-05-17 18:14:43 +00005271- Patch #957650: "%var%" environment variable references are now
5272 properly expanded in ntpath.expandvars(), also "~user" home
5273 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00005274
Georg Brandl3ee81df2008-05-17 18:14:43 +00005275- Patch #1429539: pdb now correctly initializes the __main__ module
5276 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005277 correctly now.
5278
Georg Brandlbad6f192007-03-13 21:32:56 +00005279- The nonobvious commands.getstatus() function is now deprecated.

5285
Georg Brandl3ee81df2008-05-17 18:14:43 +00005286- Patch #1530482: add pydoc.render_doc() which returns the
5287 documentation for a thing instead of paging it to stdout, which
5288 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00005289
Georg Brandl3ee81df2008-05-17 18:14:43 +00005290- Patch #1533909: the timeit module now accepts callables in addition

5297 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00005299- Patch #1581073: add a flag to textwrap that prevents the dropping of
5300 whitespace while wrapping.
5301
Georg Brandl92a6bae2007-03-13 17:43:32 +00005302- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005303 are set for invalid interpolation sequences that would lead to
5304 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00005305

5318
Georg Brandl94fe3f52007-03-13 09:32:11 +00005319- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00005320 field names in its exception message if you try to write a record
5321 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00005339

5347 returned string up to the first NUL character.
5348

5358
Georg Brandl3ee81df2008-05-17 18:14:43 +00005359- unittest now verifies more of its assumptions. In particular,
5360 TestCase and TestSuite subclasses (not instances) are no longer
5361 accepted in TestSuite.addTest(). This should cause no
5362 incompatibility since it never made sense with ordinary subclasses
5363 -- the failure just occurred later, with a more cumbersome
5364 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00005365

5373 given a unicode argument and os.listdir() returns unicode filenames.
5374
Georg Brandl3ee81df2008-05-17 18:14:43 +00005375- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00005753 time so that opening a database previously created with the DB_DUP
5754 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5755 opens. Specifically: dictionary assignment to a DB object will
5756 replace all values for a given key when the database allows
5757 duplicate values. DB users should use DB.put(k, v) when they want
5758 to store duplicates; not DB[k] = v.

5765 characters with ASCII value less than 32. Also, it correctly quotes
5766 dots only if they occur on a single line, as opposed to the previous
5767 behavior of quoting dots if they are the second character of any
5768 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005769
