Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000127- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
128 start byte and the continuation byte(s) are now considered invalid, instead
129 of the number of bytes specified by the start byte.
130 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
131 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
132 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
133 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000135- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000136 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
137 arises from the "Overriding __eq__ blocks inheritance ..." warning
138 when turned into an exception: in this case the exception simply
139 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000141- Issue #8748: Fix two issues with comparisons between complex and integer
142 objects. (1) The comparison could incorrectly return True in some cases
143 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
144 (2) The comparison raised an OverflowError for large integers, leading
145 to unpredictable exceptions when combining integers and complex objects
146 in sets or dicts.
147
Mark Dickinson81336372010-05-30 12:12:25 +0000148- Issue #5211: Implicit coercion for the complex type is now completely
149 removed. (Coercion for arithmetic operations was already removed in 2.7
150 alpha 4, but coercion for rich comparisons was accidentally left in.)
151
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000152- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +0000155- Issue #7902: When using explicit relative import syntax, don't try implicit

1023 ``io.BufferedReader`` object for more speedups. It also solves an issue
1024 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1120
Mark Dickinson1b34d252010-01-01 17:27:30 +00001121- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001122 DeprecationWarning when passed a float argument where an integer was expected.
1123 These functions and methods now raise TypeError instead. The majority of the
1124 effects of this change are in the extension modules, but some core functions
1125 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1126 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00001288- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1289 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001290
Georg Brandlba83f822010-03-14 09:50:54 +00001291- Issue #3382: 'F' formatting for float and complex now convert the result to
1292 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1293 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001294
Georg Brandlba83f822010-03-14 09:50:54 +00001295- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1296 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001297
Georg Brandlba83f822010-03-14 09:50:54 +00001298- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1299 1e-100 used to raise OverflowError, but now gives the requested 120
1300 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001301
Georg Brandlba83f822010-03-14 09:50:54 +00001302- Add Py3k warnings for parameter names in parentheses.

1307 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001308
Georg Brandlba83f822010-03-14 09:50:54 +00001309- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1310 decimal string that's guaranteed to round back to x under correct rounding
1311 (with round-half-to-even rounding mode). Previously it gave a string based on
1312 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1313 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1314 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001315
Georg Brandlba83f822010-03-14 09:50:54 +00001316- Issue #7117: On almost all platforms: float-to-string and string-to-float
1317 conversions within Python are now correctly rounded. Places these conversions
1318 occur include: str for floats and complex numbers; the float and complex
1319 constructors; old-style and new-style numeric formatting; serialization and
1320 deserialization of floats and complex numbers using marshal, pickle and json;
1321 parsing of float and imaginary literals in Python code; Decimal-to-float
1322 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001323
Georg Brandlba83f822010-03-14 09:50:54 +00001324 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1325 providing correctly-rounded strtod and dtoa C functions. This code is
1326 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1327 the C compiler. There may be a small number of platforms on which correct
1328 operation of this code cannot be guaranteed, so the code is not used: notably,
1329 this applies to platforms where the C double format is not IEEE 754 binary64,
1330 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1331 and Python's configure script is unable to determine how to change the FPU
1332 precision. On these platforms conversions use the platform strtod and dtoa,
1333 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001334
Georg Brandlba83f822010-03-14 09:50:54 +00001335- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1336 uses the correctly-rounded string <-> float conversions described above (when
1337 available), and so produces correctly rounded results that will display nicely
1338 under the float repr. There are two related small changes: (1) round now
1339 accepts any class with an ``__index__()`` method for its second argument (but
1340 no longer accepts floats for the second argument), and (2) an excessively
1341 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1342 raises an exception.

1345
Georg Brandlba83f822010-03-14 09:50:54 +00001346- Fix several issues with ``compile()``. The input can now contain Windows and
1347 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00001348

1378 The tables for code points representing numeric values, white spaces or line
1379 breaks are now generated from the official Unicode Character Database files,
1380 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00001489- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1490 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1491 but with at least one decimal point and with a default precision
1492 of 12. Previously, the behavior the same but with a default precision of 6.
1493 This more closely matches ``str()``, and reduces surprises when adding
1494 alignment flags to the empty presentation type. This also affects the new
1495 complex.__format__ in the same way.

3122
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003123- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3124
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003125- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3126 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3127 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3128 ``printf`` function, whereas PyString_FromFormat has an independent
3129 implementation and uses "%zd" on all platforms for size_t values.
3130 This makes a difference on win64, where ``printf`` needs "%Id" to display
3131 64bit values.
3132
Benjamin Peterson97179b02008-09-09 20:55:01 +00003133- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3134 error.
3135
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003136- Issue #3777: long() applied to a float object now always return a long
3137 object; previously an int would be returned for small values. the __long__
3138 method is allowed to return either an int or a long, but the behaviour of
3139 float objects should not change to respect backward compatibility.
3140
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003141- Issue #3751: str.rpartition would perform a left-partition when called with
3142 a unicode argument.
3143
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003144- Issue #3683: Fix compilation when --without-threads is given.
3145
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003146- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003147 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003148 was correctly parsed but parsing of subsequent arguments failed.
3149
Vinay Sajip35e3b032008-09-01 14:33:59 +00003150- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003151 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3152 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3153 when given a tuple of classes as second argument, were looking up
3154 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3155 type object.
3156
Neal Norwitz18aa3882008-08-24 05:04:52 +00003157- Fix crashes on memory allocation failure found with failmalloc.
3158
3159- Fix memory leaks found with valgrind and update suppressions file.
3160
3161- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3162
3163- Fix problem using wrong name in decimal module reported by pychecker.
3164
Christian Heimes7d4c3172008-08-22 19:47:25 +00003165- Silenced another compiler warning about a used but not defined
3166 function 'stringlib_contains_obj'.
3167
Benjamin Peterson712ee922008-08-24 18:10:20 +00003168- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3169 ``__delslice__``.
3170
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003171- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3172 library targets in the Makefile.
3173
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003174- Issue #1204: The configure script now tests for additional libraries
3175 that may be required when linking against readline. This fixes issues
3176 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
3177

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00003186- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
3187 stack usage in the case of deeply nested objects.
3188
Guido van Rossume3c4fd92008-09-10 14:27:00 +00003189- Issue #3629: Fix sre "bytecode" validator for an end case.
3190
Martin v. Löwis24329ba2008-09-10 13:38:12 +00003191- Issue #3811: The Unicode database was updated to 5.1.
3192
Nick Coghland2e09382008-09-11 12:11:06 +00003193- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
3194 silent misbehaviour when a single instance is nested in multiple
3195 with statements, or when the methods are invoked in the wrong order.
3196
Vinay Sajip844f7412008-09-09 13:42:08 +00003197- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
3198
Nick Coghland2e09382008-09-11 12:11:06 +00003199- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003200 return a list or None rather than a custom object.
3201
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003202- Issue #1638033: Cookie.Morsel gained the httponly attribute.
3203
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00003204- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

3209 its symbolic link.
3210
Vinay Sajip65d66e12008-09-04 07:31:21 +00003211- Issue #3772: Fixed regression problem in StreamHandler.emit().

3224
Brett Cannon1eaf0742008-09-02 01:25:16 +00003225- Issue 3602: Moved test.test_support.catch_warning() to
3226 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3227 for catch_warnings() also led to an improvement in the raising of a
3228 DeprecationWarning related to warnings.warn_explicit().
3229
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003230- The deprecation warnings for the old camelCase threading API were removed.

Christian Heimesa27a62e2008-08-22 19:55:54 +00003234- Silenced a trivial compiler warning in the sqlite module.
3235
Christian Heimes1cc69632008-08-22 20:10:27 +00003236- Fixed two format strings in the _collections module.
3237

3239 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00003240
Gregory P. Smithd7122032008-09-02 05:36:11 +00003241- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
3242 non-integer floating point number.
3243
Vinay Sajip65d66e12008-09-04 07:31:21 +00003244- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

3251 _check_logger_class from multiprocessing.
3252
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003253- Issue #2975: When compiling several extension modules with Visual Studio 2008
3254 from the same python interpreter, some environment variables would grow
3255 without limit.
3256
Benjamin Peterson37346b22008-08-23 20:27:43 +00003257- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3258 exploitation of poor argument checking.
3259
Gerhard Häringef2276b2008-09-12 13:54:06 +00003260- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3261
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003262- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3263 remaining ones have "pysqlite_" prefix.
3264
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003265- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00003272- Issue #3781: Add test.test_support.check_warnings() as a convenience
3273 wrapper for warnings.catch_warnings() that makes it easier to check
3274 that expected warning messages are being reported.
3275
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003276- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003294What's New in Python 2.6 beta 3?
3295================================
3296
Barry Warsaw07a4a382008-08-21 01:15:08 +00003297*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003298
3299Core and Builtins
3300-----------------
3301
Guido van Rossumf8402962008-08-20 15:01:50 +00003302- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3303 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3304 extensions do not automatically benefit from the class attribute
3305 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3306 to their tp_flags field if they care. This is a backwards
3307 compatibility feature; in 3.0, all types will use the cache by
3308 default.
3309
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003310- Keyword arguments can now follow starred arguments. (``f(a, *args,
3311 keyword=23)`` is now valid syntax.)
3312
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003313- ctypes function pointers that are COM methods have a boolean True
3314 value again.
3315
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003316- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3317 by denying s# to parse objects that have a releasebuffer procedure,
3318 and introducing s*.
3319
Georg Brandl1e13ea92008-08-11 09:07:59 +00003320- Issue #3537: Fix an assertion failure when an empty but presized dict
3321 object was stored in the freelist.
3322
Mark Dickinsonb6467572008-08-04 21:30:09 +00003323- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3324 ValueError consistently across platforms.
3325
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003326- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3327 (64bit Unix, for example), unichr() would truncate its argument and return
3328 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3329
Neal Norwitze7d8be82008-07-31 17:17:14 +00003330- Apply security patches from Apple.
3331
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003332- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3333 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3334
Antoine Pitrou92f82162008-07-25 22:22:08 +00003335- Issue #1819: function calls with several named parameters are now on
3336 average 35% faster (as measured by pybench).
3337
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003338- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3339 the python debugger steps into a class statement: the free variables (local
3340 variables defined in an outer scope) would be deleted from the outer scope.
3341
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003342- Issue #2620: Overflow checking when allocating or reallocating memory
3343 was not always being done properly in some python types and extension
3344 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3345 all been updated to perform better checks and places in the code that
3346 would previously leak memory on the error path when such an allocation
3347 failed have been fixed.

3350-------
3351
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003352- Issue #3612: Added some missing basic types in ctypes.wintypes.
3353
Benjamin Petersone977ad42008-08-20 01:42:01 +00003354- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3355 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3356
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003357- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3358 version reported by these tools does not necessarily follow the python
3359 version numbering scheme, so the module is less strict when parsing it.
3360
Nick Coghlanf70385a2008-08-18 12:42:46 +00003361- Issue #2235: Added Py3k warnings for types which will become unhashable
3362 under the stricter __hash__ inheritance rules in 3.0. Several types
3363 which did not meet the rules for hash invariants and were already
3364 unhashable in 3.0 have now been explicitly flagged as unhashable in
3365 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3366 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3367
Brett Cannon88f801d2008-08-18 00:46:22 +00003368- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3369 imported into the module but exposed as part of the module's API.
3370
Brett Cannon7b96f072008-08-18 00:41:11 +00003371- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3372
Brett Cannon46225e72008-08-18 00:36:52 +00003373- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003375- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3376
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003377- Issue #3575: Incremental decoder's decode function now takes bytearray
3378 by using 's*' instead of 't#'.
3379
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003380- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003381 fails unicode conversion on 2nd parameter. (windows only)
3382
Facundo Batista94f243a2008-08-17 03:38:39 +00003383- Issue 2464. urllib2 now supports a malformation in the URL received
3384 in a redirect.
3385
Brett Cannonabe423e2008-08-16 21:47:07 +00003386- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003387 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003388
Facundo Batistaeb90b782008-08-16 14:44:07 +00003389- Issue #2776: fixed small issue when handling an URL with double slash
3390 after a 302 response in the case of not going through a proxy.
3391
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003392- Issue #2676: in the email package, content-type parsing was hanging on
3393 pathological input because of quadratic or exponential behaviour of a
3394 regular expression.
3395
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003396- Issue #3476: binary buffered reading through the new "io" library is now
3397 thread-safe.
3398
Brett Cannonbf3157b2008-08-14 05:00:03 +00003399- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3400 since mimetools itself is deprecated. Because modules are cached, all
3401 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3402
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003403- Issue #3134: shutil referenced undefined WindowsError symbol.
3404
Robert Schuppenies14646332008-08-10 11:01:53 +00003405- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3406 menu entries were not deleted.
3407
Brett Cannon83e81842008-08-09 23:30:55 +00003408- Copied the implementation of reduce() to _functools.reduce() to have a
3409 version that did not raise a DeprecationWarning under -3.
3410
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003411- Issue #3205: When iterating over a BZ2File fails allocating memory, raise

3415 to _sre.compile() will now be rejected. This should not affect anybody
3416 since the re.compile() function never generates invalid re-bytecode.

Benjamin Peterson01a24322008-07-28 23:35:27 +00003436- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003437 asking for a specific length. This problem only affected files opened
3438 using the new "io" module, not the built-in open() function.

3465 mode 0600 rather than 000 under Unix.
3466
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003467- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3481
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003482- Issue #643841: The language reference now provides more detailed

3494-----------------
3495
Georg Brandl3e483f62008-07-16 22:57:41 +00003496- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3497 its methods now allow for items objects that can be converted to
3498 an integer using operator.index().
3499
Mark Dickinson64b7e502008-07-16 09:40:03 +00003500- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3501 produced a ValueError instead of giving the correct float.
3502
Eric Smitha5fa5a22008-07-16 00:11:49 +00003503- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3504 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3505
Mark Dickinson7103aa42008-07-15 19:08:33 +00003506- Issue #3008: the float type has a new instance method 'float.hex'
3507 and a new class method 'float.fromhex' to convert floating-point
3508 numbers to and from hexadecimal strings, respectively.
3509
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003510- Issue #2235: __hash__ is once again inherited by default. To allow
3511 collections.Hashable to remain meaningful in the presence of the
3512 default hash implementation (object.__hash__), it is now possible
3513 to explicit block inheritance of hash by setting __hash__=None at
3514 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3515 level.
3516
Nick Coghlanb028f502008-07-13 14:52:36 +00003517- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3518 the parent module cannot be found while performing an absolute import.
3519 This means that an incorrectly defined __package__ attribute will
3520 now only prevent relative imports in that module rather than causing
3521 all imports from that module to fail.
3522
Nick Coghlan14ff9942008-07-08 14:21:42 +00003523- Issue #2517: Allow unicode messages in Exceptions again by correctly

3533 another thread's dictionary.
3534
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003535- Issue #3004: Minor change to slice.indices(): the start and stop
3536 arguments are now treated identically, making the behaviour easier
3537 to describe and understand. For example, slice(None, -10,
3538 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3539 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3540 10, -1).
3541
Georg Brandl278fc502008-07-19 12:46:12 +00003542- Issue #3219: Calling a function with repeated keyword arguments,
3543 f(a=2, a=23), would not cause a syntax error. This was a regression
3544 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00003546- Issue #2862: Make int and float freelist management consistent with
3547 other freelists. Changes their CompactFreeList apis into

3554 api functions without holding the GIL, which could lead to a fatal
3555 error when they failed.
3556
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003557- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003582- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3583 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003584 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003585 content-length. The problem had been corrected in the 2.4 branch, but never
3586 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003601- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3603
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003604- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

3989
Brett Cannonb61d8012008-05-11 23:39:04 +00003990- ``Lib/lib-old`` is now added to sys.path.
3991
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003992- On MacOS X it is now possible to install the framework in 64-bit
3993 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003994 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003995
3996 This is controlled by the configure argument ``--with-universal-archs``:
3997
3998 - ``--with-universal-archs=all``: install 4-way universal
3999
4000 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4001
4002 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4003
4004 This option should be used in combination with ``--enable-universalsdk=``.
4005
4006 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00004015
4016- The PyString functions have been renamed to PyBytes. A batch of
4017 defines were added so that the linker still sees the original
4018 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004056- Issue #1631171: Re-implement the 'warnings' module in C (the
4057 original Python code has been kept as backup). This will allow for
4058 using the 'warning's machinery in such places as the parser where
4059 use of pure Python code is not possible. Both the ``showarning()``
4060 and ``formatwarning()`` gain an optional 'line' argument which is
4061 not called by default for backwards-compatibility reasons. Setting
4062 ``warnings.showwarning()`` to an implementation that lacks support
4063 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004088- The getpass module has been improved on Unix. It now uses /dev/tty
4089 by default and uses stderr instead of stdout. A GetPassWarning is
4090 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004105- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004106 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004126- Issue #2550: The approach used by client/server code for obtaining
4127 ports to listen on in network-oriented tests has been refined in an
4128 effort to facilitate running multiple instances of the entire
4129 regression test suite in parallel without issue.
4130 test_support.bind_port() has been fixed such that it will always
4131 return a unique port -- which wasn't always the case with the
4132 previous implementation, especially if socket options had been set
4133 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4134 new implementation of bind_port() will actually raise an exception
4135 if it is passed an AF_INET/SOCK_STREAM socket with either the
4136 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4137 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4138 the socket it's been passed. This currently only applies to
4139 Windows. This option prevents any other sockets from binding to the
4140 host/port we've bound to, thus removing the possibility of the
4141 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4142 when a second SOCK_STREAM socket binds and accepts to a host/port
4143 that's already been bound by another socket. The optional preferred
4144 port parameter to bind_port() has been removed. Under no
4145 circumstances should tests be hard coding ports!
4146
4147 test_support.find_unused_port() has also been introduced, which will
4148 pass a temporary socket object to bind_port() in order to obtain an
4149 unused port. The temporary socket object is then closed and
4150 deleted, and the port is returned. This method should only be used
4151 for obtaining an unused port in order to pass to an external program
4152 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4153 a parameter to a server-oriented class that doesn't give you direct
4154 access to the underlying socket used.
4155
4156 Finally, test_support.HOST has been introduced, which should be used
4157 for the host argument of any relevant socket calls (i.e. bind and
4158 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004159
4160 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004161 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004162 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4163 test_asynchat and test_socket_ssl.
4164
Georg Brandl3ee81df2008-05-17 18:14:43 +00004165 It is now possible for multiple instances of the regression test
4166 suite to run in parallel without issue.

4433-----------------
4434
Fred Drakea8ee94b2008-03-01 02:45:07 +00004435- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004436 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004437

4439
4440- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004441
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004442- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004443 issue 215555 for a discussion.
4444
Eric Smitha73fbe72008-02-23 03:09:44 +00004445- Added the future_builtins module, which contains hex() and oct().
4446 These are the PEP 3127 version of these functions, designed to be
4447 compatible with the hex() and oct() builtins from Python 3.0. They
4448 differ slightly in their output formats from the existing, unchanged
4449 Python 2.6 builtins. The expected usage of the future_builtins
4450 module is:
4451 from future_builtins import hex, oct
4452
Eric Smith7ef40bf2008-02-20 23:34:22 +00004453- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4454 exponents for exponents with absolute value < 100. Follows C99
4455 standard. This is a change on Windows, which would use 3 digits.
4456 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4457 so that any alterations it does to the resulting string will be
4458 available in stringlib/formatter.h (for float.__format__).
4459
Eric Smith5a3c1352008-02-19 13:21:56 +00004460- Implemented PEP 3101, Advanced String Formatting. This adds a new
4461 builtin format(); a format() method for str and unicode; a
4462 __format__() method to object, str, unicode, int, long, float, and
4463 datetime; the class string.Formatter; and the C API
4464 PyObject_Format().
4465
Georg Brandl3ee81df2008-05-17 18:14:43 +00004466- Fixed several potential crashes, all caused by specially crafted
4467 __del__ methods exploiting objects in temporarily inconsistent
4468 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004469
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004470- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004471 prevent a possible crash: an Abstract Base Class would try to access
4472 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004473

Georg Brandl3ee81df2008-05-17 18:14:43 +00004477- Clear all free lists during a gc.collect() of the highest generation
4478 in order to allow pymalloc to free more arenas. Python may give back
4479 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004480
Georg Brandl3ee81df2008-05-17 18:14:43 +00004481- Issue #2045: Fix an infinite recursion triggered when printing a
4482 subclass of collections.defaultdict, if its default_factory is set
4483 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004484
Christian Heimesf75dbef2008-02-08 00:11:31 +00004485- Fixed a minor memory leak in dictobject.c. The content of the free
4486 list was not freed on interpreter shutdown.
4487
Georg Brandl21e99f42010-03-07 15:23:59 +00004488- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004489 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004490
Georg Brandl3ee81df2008-05-17 18:14:43 +00004491- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4492 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004493 to compact the internal free lists of pre-allocted ints and floats.
4494
Georg Brandl3ee81df2008-05-17 18:14:43 +00004495- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4496 calls. Python expected the return type int but the fork familie
4497 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004498
Georg Brandl3ee81df2008-05-17 18:14:43 +00004499- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4500 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004501
Georg Brandl3ee81df2008-05-17 18:14:43 +00004502- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4503 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004504
Georg Brandl3ee81df2008-05-17 18:14:43 +00004505- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4506 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004508- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4509 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004510
Georg Brandl3ee81df2008-05-17 18:14:43 +00004511- Patch #1473257: generator objects gain a gi_code attribute. This is
4512 the same object as the func_code attribute of the function that
4513 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004514
Georg Brandl3ee81df2008-05-17 18:14:43 +00004515- Issue #1920: "while 0" statements were completely removed by the
4516 compiler, even in the presence of an "else" clause, which is
4517 supposed to be run when the condition is false. Now the compiler
4518 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004519
Guido van Rossumeead05f2008-01-24 18:21:02 +00004520- A few crashers fixed: weakref_in_del.py (issue #1377858);
4521 loosing_dict_ref.py (issue #1303614, test67.py);
4522 borrowed_ref_[34].py (not in tracker).
4523
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004524- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004525 suppressed while an extension is loaded by calling SetErrorMode in
4526 dynload_win.c. The error is still reported properly.
4527
Georg Brandl3ee81df2008-05-17 18:14:43 +00004528- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004529 several extension methods and modules do not work without unicode
4530 support.
4531
Georg Brandl26543b12008-01-21 18:36:51 +00004532- Issue #1882: when compiling code from a string, encoding cookies in the
4533 second line of code were not always recognized correctly.
4534
Georg Brandl14404b62008-01-19 19:27:05 +00004535- Issue #1679: "0x" was taken as a valid integer literal.
4536
Georg Brandl6caad7d2008-01-26 14:19:22 +00004537- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004538 added.
4539
Christian Heimesc94e2b52008-01-14 04:13:37 +00004540- sys.float_info / PyFloat_GetInfo: The floating point information
4541 object was converted from a dict to a specialized structseq object.
4542
Georg Brandl3ee81df2008-05-17 18:14:43 +00004543- Patch #1816: Added sys.flags structseq. It exposes the status of
4544 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004545
Georg Brandl3ee81df2008-05-17 18:14:43 +00004546- Objects/structseq.c: Implemented new structseq representation. The
4547 patch makes structseqs (e.g. the return value of os.stat) more
4548 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004549
Georg Brandl3ee81df2008-05-17 18:14:43 +00004550- Patch #1700288: added a type attribute cache that caches method
4551 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004552
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004553- Bug #1776: __import__() no longer accepts filenames on any platform.
4554 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004555
Georg Brandlaed6c662008-01-07 17:25:53 +00004556- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4557
Georg Brandl3ee81df2008-05-17 18:14:43 +00004558- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4559 envvar and sys.dont_write_bytecode attribute. All these can be set
4560 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004561
Georg Brandl3ee81df2008-05-17 18:14:43 +00004562- Improve some exception messages when Windows fails to load an
4563 extension module. Now we get for example '%1 is not a valid Win32
4564 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004565

Christian Heimes0a8143f2007-12-18 23:22:54 +00004571- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004572 and INF. float("nan"), float("inf") and float("-inf") now work on
4573 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004574
Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- Compiler now generates simpler and faster code for dictionary
4576 literals. The oparg for BUILD_MAP now indicates an estimated
4577 dictionary size. There is a new opcode, STORE_MAP, for adding
4578 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004607- Patch #1739468: Directories and zipfiles containing a __main__.py
4608 file can now be directly executed by passing their name to the
4609 interpreter. The directory/zipfile is automatically inserted as the
4610 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004611
Georg Brandl3ee81df2008-05-17 18:14:43 +00004612- Issue #1265: Fix a problem with sys.settrace, if the tracing
4613 function uses a generator expression when at the same time the
4614 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004615
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004616- sets and frozensets now have an isdisjoint() method.
4617
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004618- optimize the performance of builtin.sum().
4619
Neal Norwitz44f326e2007-10-05 05:29:17 +00004620- Fix warnings found by the new version of the Coverity checker.
4621
Georg Brandl21e99f42010-03-07 15:23:59 +00004622- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004623 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4624 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004625
Georg Brandl3ee81df2008-05-17 18:14:43 +00004626- Issue #1686386: Tuple's tp_repr did not take into account the
4627 possibility of having a self-referential tuple, which is possible
4628 from C code. Nor did object's tp_str consider that a type's tp_str
4629 could do something that could lead to an inifinite recursion.
4630 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4631 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004632
Georg Brandl3ee81df2008-05-17 18:14:43 +00004633- Issue #1164: It was possible to trigger deadlock when using the
4634 'print' statement to write to a file since the GIL was not released
4635 as needed. Now PyObject_Print() does the right thing along with
4636 various tp_print implementations of the built-in types and those in
4637 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004638
Georg Brandl3ee81df2008-05-17 18:14:43 +00004639- Issue #1147: Exceptions were directly allowing string exceptions in
4640 their throw() method even though string exceptions no longer
4641 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004643- Issue #1096: Prevent a segfault from getting the repr of a very
4644 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004645
Brett Cannon1e534b52007-09-07 04:18:30 +00004646- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004647 PyObject_Call() never calling back out to Python code to trigger
4648 recursion depth updates/checks. Required the creation of a static
4649 RuntimeError instance in case normalizing an exception put the
4650 recursion check value past its limit. Fixes crashers
4651 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004652

Neal Norwitz0ac60192007-05-27 04:08:54 +00004666- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004667 __*__ attributes. (Some already existed, e.g., __doc__ and
4668 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004669
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004670- Add -3 option to the interpreter to warn about features that are
4671 deprecated and will be changed/removed in Python 3.0.
4672
Georg Brandl2134e752007-05-21 20:34:16 +00004673- Patch #1686487: you can now pass any mapping after '**' in function
4674 calls.
4675
Collin Winter62903052007-05-18 23:11:24 +00004676- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004677 "except E as target:". This is to provide forwards compatibility
4678 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00004680- Deprecate BaseException.message as per PEP 352.
4681
Georg Brandl3ee81df2008-05-17 18:14:43 +00004682- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004683 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004684
Vinay Sajip8549ce32007-05-06 17:53:37 +00004685- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004686 setting a plain string, ie don't expand to single letter identifiers.
4687
Raymond Hettinger13936692007-04-11 18:40:58 +00004688- Request #1191699: Slices can now be pickled.
4689
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004690- Request #1193128: str.translate() now allows a None argument for
4691 translations that only remove characters without re-mapping the
4692 remaining characters.
4693
Georg Brandl5cb76c12007-03-21 09:00:39 +00004694- Patch #1682205: a TypeError while unpacking an iterable is no longer
4695 masked by a generic one with the message "unpack non-sequence".
4696
Neal Norwitzaa754b72007-03-21 06:39:48 +00004697- Remove unused file Python/fmod.c.
4698
Guido van Rossum143b5642007-03-23 04:58:42 +00004699- Bug #1683368: The object.__init__() and object.__new__() methods are
4700 now stricter in rejecting excess arguments. The only time when
4701 either allows excess arguments is when it is not overridden and the
4702 other one is. For backwards compatibility, when both are
4703 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004704 warning later). Also, type.__init__() insists on the same signature
4705 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004706
Georg Brandl3ee81df2008-05-17 18:14:43 +00004707- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4708 object to complex using its __complex__() method before falling back
4709 to the __float__() method. Therefore, the functions in the cmath
4710 module now can operate on objects that define a __complex__()
4711 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004713- Patch #1623563: allow __class__ assignment for classes with
4714 __slots__. The old and the new class are still required to have the
4715 same slot names.

4728
Georg Brandl7b9c5552007-03-12 14:30:05 +00004729- Bug #1678647: write a newline after printing an exception in any
4730 case, even when converting the value to a string failed.
4731
Georg Brandl871f1bc2007-03-12 13:17:36 +00004732- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004733 its argument, if it exists. If not, it will work like before. This
4734 allows customizing the output of dir() in the presence of a
4735 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005259 the client's request was successfully received, understood, and

5271 work started with create_connection() and timeout in httplib, and

5273
Vinay Sajip8549ce32007-05-06 17:53:37 +00005274- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00005300 AttributeError instead of an IOError when the server's response
5301 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005335 are set for invalid interpolation sequences that would lead to
5336 errors on reading back those values.

5392 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00005785 time so that opening a database previously created with the DB_DUP
5786 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5787 opens. Specifically: dictionary assignment to a DB object will
5788 replace all values for a given key when the database allows
5789 duplicate values. DB users should use DB.put(k, v) when they want
5790 to store duplicates; not DB[k] = v.

5797 characters with ASCII value less than 32. Also, it correctly quotes
5798 dots only if they occur on a single line, as opposed to the previous
5799 behavior of quoting dots if they are the second character of any
5800 line.
