Florent Xiclunac2279652012-02-12 14:49:03 +0100310- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100311 has left two versions of customize_compiler, the original in
312 distutils.sysconfig and another copy in distutils.ccompiler, with some
313 parts of distutils calling one and others using the other.
314 Complete the revert back to only having one in distutils.sysconfig as
315 is the case in 3.x.
316
Ned Deily0d0ea482012-02-10 12:59:06 +0100317- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
318 Distutils-based packages with C extension modules may fail because
319 Apple has removed gcc-4.2, the version used to build python.org
320 64-bit/32-bit Pythons. If the user does not explicitly override
321 the default C compiler by setting the CC environment variable,
322 Distutils will now attempt to compile extension modules with clang
323 if gcc-4.2 is required but not found. Also as a convenience, if
324 the user does explicitly set CC, substitute its value as the default
325 compiler in the Distutils LDSHARED configuration variable for OS X.
326 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
327 SDK, neither of which are available in Xcode 4. This change does not
328 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700601- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
602 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
603 interpreter process. This could cause failures in non-Distutils subprocesses
604 and was unreliable since tests or user programs could modify the interpreter
605 environment after Distutils set it. Instead, have Distutils set the the
606 deployment target only in the environment of each build subprocess. It is
607 still possible to globally override the default by setting
608 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
609 greater or equal to the default value, the value with which the interpreter
610 was built.

640 the ticker doesn't have to wind down to zero from the old starting point

642 interval, it makes sure the new limit takes effect right away rather have an
643 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00001587- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1588 This prevents user-created self-referencing ordered dictionaries from
1589 becoming permanently uncollectable GC garbage. The downside is that
1590 removing __del__ means that the internal doubly-linked list has to wait for
1591 GC collection rather than freeing memory immediately when the refcnt drops
1592 to zero.
1593

1600 to fetch the original errno, or to filter timeout errors. Now the
1601 original error is re-raised.

1622
R. David Murray7c4bf552010-08-25 01:45:57 +00001623- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1624 character years even if the message contains RFC822 two character years.
1625
Daniel Stutzbach91287322010-08-24 21:09:30 +00001626- Issue #8750: Fixed MutableSet's methods to correctly handle

1639
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001640- Issue #9617: Signals received during a low-level write operation aren't
1641 ignored by the buffered IO layer anymore.
1642
Benjamin Peterson52c36052010-08-21 03:03:22 +00001643- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1645
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001646- Issue #9626: the view methods for collections.OrderedDict() were returning
1647 the unordered versions inherited from dict. Those methods are now
1648 overridden to provide ordered views.

1655 and a BadZipfile error is raised if it doesn't match (as used to be the
1656 case in Python 2.5 and earlier).
1657
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001658- Issue #9550: a BufferedReader could issue an additional read when the
1659 original read request had been satisfied, which could block indefinitely
1660 when the underlying raw IO channel was e.g. a socket. Report and original
1661 patch by Jason V. Miller.

Fred Drake0a1fa0e2010-08-10 13:09:54 +00001663- Issue #9551: Don't raise TypeError when setting the value to None for

2055 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2056 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2057 Previous versions returned a single u'\ufffd'.

2067 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00002311- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
2312 the method could block indefinitely if called just before the event loop
2313 started running. This also fixes the occasional freezes witnessed in
2314 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +00002316- Issue #5103: SSL handshake would ignore the socket timeout and block
2317 indefinitely if the other end didn't respond.
2318
Georg Brandlfee0f442010-05-22 21:26:21 +00002319- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002412 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

2438
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002439- Issue #8329: Don't return the same lists from select.select when no fds are
2440 changed.
2441
Georg Brandlfee0f442010-05-22 21:26:21 +00002442- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002443 on 64-bit machines. The shift count for either left or right shift is
2444 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00002452- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2453 with a non-empty format string. This is an effort to future-proof user
2454 code. If a derived class does not currently implement __format__ but later
2455 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002456 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002457 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002490- Issue #8257: The Decimal construct now accepts a float instance directly,
2491 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002492

Georg Brandlfee0f442010-05-22 21:26:21 +00002507- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2508 InvalidOperation instead of returning False. (Comparisons involving a quiet
2509 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2510 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002511
Georg Brandlfee0f442010-05-22 21:26:21 +00002512- Issue #2531: Comparison operations between floats and Decimal instances now
2513 return a result based on the numeric values of the operands; previously they
2514 returned an arbitrary result based on the relative ordering of id(float) and
2515 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00002529- Comparisons using one of <, <=, >, >= between a complex instance and a
2530 Fractions instance now raise TypeError instead of returning True/False. This
2531 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2532 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002950 file position when calling `truncate()`. It would previously change the file
2951 position to the given argument, which goes against the tradition of

3048
Georg Brandlba83f822010-03-14 09:50:54 +00003049- The ``__complex__()`` method is now looked up on the class of instances to
3050 make it consistent with other special methods.

3054
Mark Dickinson1b34d252010-01-01 17:27:30 +00003055- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003056 DeprecationWarning when passed a float argument where an integer was expected.
3057 These functions and methods now raise TypeError instead. The majority of the
3058 effects of this change are in the extension modules, but some core functions
3059 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3060 and many unicode/str methods.

3072
Georg Brandlba83f822010-03-14 09:50:54 +00003073- Issue #1811: Improve accuracy and cross-platform consistency for true division
3074 of integers: the result of a/b is now correctly rounded for ints a and b (at
3075 least on IEEE 754 platforms), and in particular does not depend on the
3076 internal representation of a long.

3084
Georg Brandlba83f822010-03-14 09:50:54 +00003085 These executables now work properly with the arch(1) command: ``arch -ppc
3086 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00003250- Issue #7117: On almost all platforms: float-to-string and string-to-float
3251 conversions within Python are now correctly rounded. Places these conversions
3252 occur include: str for floats and complex numbers; the float and complex
3253 constructors; old-style and new-style numeric formatting; serialization and
3254 deserialization of floats and complex numbers using marshal, pickle and json;
3255 parsing of float and imaginary literals in Python code; Decimal-to-float
3256 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003257
Georg Brandlba83f822010-03-14 09:50:54 +00003258 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3259 providing correctly-rounded strtod and dtoa C functions. This code is
3260 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3261 the C compiler. There may be a small number of platforms on which correct
3262 operation of this code cannot be guaranteed, so the code is not used: notably,
3263 this applies to platforms where the C double format is not IEEE 754 binary64,
3264 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3265 and Python's configure script is unable to determine how to change the FPU
3266 precision. On these platforms conversions use the platform strtod and dtoa,
3267 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003269- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3270 uses the correctly-rounded string <-> float conversions described above (when
3271 available), and so produces correctly rounded results that will display nicely
3272 under the float repr. There are two related small changes: (1) round now
3273 accepts any class with an ``__index__()`` method for its second argument (but
3274 no longer accepts floats for the second argument), and (2) an excessively
3275 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3276 raises an exception.

4858 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4859 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4860 neither __int__ nor __long__, TypeError used to be raised (with a

4865 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005059- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

5061 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5062 ``printf`` function, whereas PyString_FromFormat has an independent
5063 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005160 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5161 for catch_warnings() also led to an improvement in the raising of a
5162 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005228What's New in Python 2.6 beta 3?
5229================================
5230
Barry Warsaw07a4a382008-08-21 01:15:08 +00005231*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005232
5233Core and Builtins
5234-----------------
5235
Guido van Rossumf8402962008-08-20 15:01:50 +00005236- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5237 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5238 extensions do not automatically benefit from the class attribute
5239 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5240 to their tp_flags field if they care. This is a backwards
5241 compatibility feature; in 3.0, all types will use the cache by
5242 default.
5243
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005244- Keyword arguments can now follow starred arguments. (``f(a, *args,
5245 keyword=23)`` is now valid syntax.)
5246
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005247- ctypes function pointers that are COM methods have a boolean True
5248 value again.
5249
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005250- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5251 by denying s# to parse objects that have a releasebuffer procedure,
5252 and introducing s*.
5253
Georg Brandl1e13ea92008-08-11 09:07:59 +00005254- Issue #3537: Fix an assertion failure when an empty but presized dict
5255 object was stored in the freelist.
5256
Mark Dickinsonb6467572008-08-04 21:30:09 +00005257- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5258 ValueError consistently across platforms.
5259
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005260- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5261 (64bit Unix, for example), unichr() would truncate its argument and return
5262 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5263
Neal Norwitze7d8be82008-07-31 17:17:14 +00005264- Apply security patches from Apple.
5265
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005266- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5267 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5268
Antoine Pitrou92f82162008-07-25 22:22:08 +00005269- Issue #1819: function calls with several named parameters are now on
5270 average 35% faster (as measured by pybench).
5271
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005272- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5273 the python debugger steps into a class statement: the free variables (local
5274 variables defined in an outer scope) would be deleted from the outer scope.
5275
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005276- Issue #2620: Overflow checking when allocating or reallocating memory
5277 was not always being done properly in some python types and extension
5278 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5279 all been updated to perform better checks and places in the code that
5280 would previously leak memory on the error path when such an allocation
5281 failed have been fixed.

5284-------
5285
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005286- Issue #3612: Added some missing basic types in ctypes.wintypes.
5287
Benjamin Petersone977ad42008-08-20 01:42:01 +00005288- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5289 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5290
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005291- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5292 version reported by these tools does not necessarily follow the python
5293 version numbering scheme, so the module is less strict when parsing it.
5294
Nick Coghlanf70385a2008-08-18 12:42:46 +00005295- Issue #2235: Added Py3k warnings for types which will become unhashable
5296 under the stricter __hash__ inheritance rules in 3.0. Several types
5297 which did not meet the rules for hash invariants and were already
5298 unhashable in 3.0 have now been explicitly flagged as unhashable in
5299 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5300 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5301
Brett Cannon88f801d2008-08-18 00:46:22 +00005302- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5303 imported into the module but exposed as part of the module's API.
5304
Brett Cannon7b96f072008-08-18 00:41:11 +00005305- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5306
Brett Cannon46225e72008-08-18 00:36:52 +00005307- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005309- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5310
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005311- Issue #3575: Incremental decoder's decode function now takes bytearray
5312 by using 's*' instead of 't#'.
5313
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005314- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005315 fails unicode conversion on 2nd parameter. (windows only)
5316
Georg Brandl222e2082010-08-01 22:27:39 +00005317- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005318 in a redirect.
5319
Brett Cannonabe423e2008-08-16 21:47:07 +00005320- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005321 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005322
Facundo Batistaeb90b782008-08-16 14:44:07 +00005323- Issue #2776: fixed small issue when handling an URL with double slash
5324 after a 302 response in the case of not going through a proxy.
5325
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005326- Issue #2676: in the email package, content-type parsing was hanging on
5327 pathological input because of quadratic or exponential behaviour of a
5328 regular expression.
5329
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005330- Issue #3476: binary buffered reading through the new "io" library is now
5331 thread-safe.
5332
Brett Cannonbf3157b2008-08-14 05:00:03 +00005333- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5334 since mimetools itself is deprecated. Because modules are cached, all
5335 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5336
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005337- Issue #3134: shutil referenced undefined WindowsError symbol.
5338
Robert Schuppenies14646332008-08-10 11:01:53 +00005339- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5340 menu entries were not deleted.
5341
Brett Cannon83e81842008-08-09 23:30:55 +00005342- Copied the implementation of reduce() to _functools.reduce() to have a
5343 version that did not raise a DeprecationWarning under -3.
5344
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005345- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5346 a MemoryError rather than silently stop the iteration.
5347
Guido van Rossum59ce9012008-08-09 14:55:34 +00005348- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5349 to _sre.compile() will now be rejected. This should not affect anybody
5350 since the re.compile() function never generates invalid re-bytecode.
5351
Skip Montanaroa032bf42008-08-08 22:52:51 +00005352- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5353 upon first access it can be automatically initialized from the csv file if
5354 it wasn't initialized during instantiation.
5355
Brett Cannon3aa2a492008-08-06 22:28:09 +00005356- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5357 the reload() built-in has been removed.
5358
Brett Cannon7e30b672008-08-04 21:52:25 +00005359- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005360 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005371 asking for a specific length. This problem only affected files opened
5372 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005373

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005397- Issue #3394: zipfile.writestr sets external attributes when passed a
5398 file name rather than a ZipInfo instance, so files are extracted with
5399 mode 0600 rather than 000 under Unix.
5400
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005401- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5402 argument in python 2.5, this broke code that subclassed Popen to include its
5403 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5415
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005416- Issue #643841: The language reference now provides more detailed
5417 coverage of the lookup process for special methods. The disclaimers
5418 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005422What's New in Python 2.6 beta 2?
5423================================
5424
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005425*Release date: 17-Jul-2008*
5426
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005427Core and Builtins
5428-----------------
5429
Georg Brandl3e483f62008-07-16 22:57:41 +00005430- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5431 its methods now allow for items objects that can be converted to
5432 an integer using operator.index().
5433
Mark Dickinson64b7e502008-07-16 09:40:03 +00005434- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5435 produced a ValueError instead of giving the correct float.
5436
Eric Smitha5fa5a22008-07-16 00:11:49 +00005437- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5438 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5439
Mark Dickinson7103aa42008-07-15 19:08:33 +00005440- Issue #3008: the float type has a new instance method 'float.hex'
5441 and a new class method 'float.fromhex' to convert floating-point
5442 numbers to and from hexadecimal strings, respectively.
5443
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005444- Issue #2235: __hash__ is once again inherited by default. To allow
5445 collections.Hashable to remain meaningful in the presence of the
5446 default hash implementation (object.__hash__), it is now possible
5447 to explicit block inheritance of hash by setting __hash__=None at
5448 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5449 level.
5450
Nick Coghlanb028f502008-07-13 14:52:36 +00005451- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5452 the parent module cannot be found while performing an absolute import.
5453 This means that an incorrectly defined __package__ attribute will
5454 now only prevent relative imports in that module rather than causing
5455 all imports from that module to fail.
5456
Nick Coghlan14ff9942008-07-08 14:21:42 +00005457- Issue #2517: Allow unicode messages in Exceptions again by correctly
5458 bypassing the instance dictionary when looking up __unicode__ on
5459 new-style classes.
5460
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005461- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5462 set to a custom object whose write() method happens to install
5463 another file in sys.stdout.
5464
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005465- Issue #3088: Corrected a race condition in classes derived from
5466 threading.local: the first member set by a thread could be saved in
5467 another thread's dictionary.
5468
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005469- Issue #3004: Minor change to slice.indices(): the start and stop
5470 arguments are now treated identically, making the behaviour easier
5471 to describe and understand. For example, slice(None, -10,
5472 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5473 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5474 10, -1).
5475
Georg Brandl278fc502008-07-19 12:46:12 +00005476- Issue #3219: Calling a function with repeated keyword arguments,
5477 f(a=2, a=23), would not cause a syntax error. This was a regression
5478 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005479
Georg Brandl278fc502008-07-19 12:46:12 +00005480- Issue #2862: Make int and float freelist management consistent with
5481 other freelists. Changes their CompactFreeList apis into
5482 ClearFreeList apis and calls them via gc.collect().

5486
Thomas Heller57adf222008-08-14 19:10:48 +00005487- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5488 api functions without holding the GIL, which could lead to a fatal
5489 error when they failed.
5490
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005491- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5500 ForkingPickler.register() to resolve conflict with ctypes.
5501
Vinay Sajip51e65192008-07-18 09:01:10 +00005502- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005503
Thomas Heller880f5292008-07-15 19:39:38 +00005504- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5505 a valid dlerror() message.

5513
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005514- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005515
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005516- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5517 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005518 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005519 content-length. The problem had been corrected in the 2.4 branch, but never
5520 merged into trunk.
5521
Georg Brandle78fbcc2008-07-05 10:13:36 +00005522- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005535- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5536 handling is now the same as that of other special attributes like __name__).
5537
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005538- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

5995 not called by default for backwards-compatibility reasons. Setting
5996 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00006060- Issue #2550: The approach used by client/server code for obtaining
6061 ports to listen on in network-oriented tests has been refined in an
6062 effort to facilitate running multiple instances of the entire
6063 regression test suite in parallel without issue.
6064 test_support.bind_port() has been fixed such that it will always
6065 return a unique port -- which wasn't always the case with the
6066 previous implementation, especially if socket options had been set
6067 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6068 new implementation of bind_port() will actually raise an exception
6069 if it is passed an AF_INET/SOCK_STREAM socket with either the
6070 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6071 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6072 the socket it's been passed. This currently only applies to
6073 Windows. This option prevents any other sockets from binding to the
6074 host/port we've bound to, thus removing the possibility of the
6075 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6076 when a second SOCK_STREAM socket binds and accepts to a host/port
6077 that's already been bound by another socket. The optional preferred
6078 port parameter to bind_port() has been removed. Under no
6079 circumstances should tests be hard coding ports!
6080
6081 test_support.find_unused_port() has also been introduced, which will
6082 pass a temporary socket object to bind_port() in order to obtain an
6083 unused port. The temporary socket object is then closed and
6084 deleted, and the port is returned. This method should only be used
6085 for obtaining an unused port in order to pass to an external program
6086 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6087 a parameter to a server-oriented class that doesn't give you direct
6088 access to the underlying socket used.
6089
6090 Finally, test_support.HOST has been introduced, which should be used
6091 for the host argument of any relevant socket calls (i.e. bind and
6092 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006093
6094 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006095 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006096 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6097 test_asynchat and test_socket_ssl.
6098
Georg Brandl3ee81df2008-05-17 18:14:43 +00006099 It is now possible for multiple instances of the regression test
6100 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006379- Added the future_builtins module, which contains hex() and oct().
6380 These are the PEP 3127 version of these functions, designed to be
6381 compatible with the hex() and oct() builtins from Python 3.0. They
6382 differ slightly in their output formats from the existing, unchanged
6383 Python 2.6 builtins. The expected usage of the future_builtins
6384 module is:
6385 from future_builtins import hex, oct
6386
Eric Smith7ef40bf2008-02-20 23:34:22 +00006387- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6388 exponents for exponents with absolute value < 100. Follows C99
6389 standard. This is a change on Windows, which would use 3 digits.
6390 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6391 so that any alterations it does to the resulting string will be
6392 available in stringlib/formatter.h (for float.__format__).
6393
Eric Smith5a3c1352008-02-19 13:21:56 +00006394- Implemented PEP 3101, Advanced String Formatting. This adds a new
6395 builtin format(); a format() method for str and unicode; a
6396 __format__() method to object, str, unicode, int, long, float, and
6397 datetime; the class string.Formatter; and the C API
6398 PyObject_Format().
6399
Georg Brandl3ee81df2008-05-17 18:14:43 +00006400- Fixed several potential crashes, all caused by specially crafted
6401 __del__ methods exploiting objects in temporarily inconsistent
6402 state.

6413 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006414
Georg Brandl3ee81df2008-05-17 18:14:43 +00006415- Issue #2045: Fix an infinite recursion triggered when printing a
6416 subclass of collections.defaultdict, if its default_factory is set
6417 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006418
Christian Heimesf75dbef2008-02-08 00:11:31 +00006419- Fixed a minor memory leak in dictobject.c. The content of the free

6428
Georg Brandl3ee81df2008-05-17 18:14:43 +00006429- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

6431 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006445- Patch #1473257: generator objects gain a gi_code attribute. This is
6446 the same object as the func_code attribute of the function that
6447 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006448
Georg Brandl3ee81df2008-05-17 18:14:43 +00006449- Issue #1920: "while 0" statements were completely removed by the
6450 compiler, even in the presence of an "else" clause, which is
6451 supposed to be run when the condition is false. Now the compiler
6452 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006453

Georg Brandl3ee81df2008-05-17 18:14:43 +00006477- Patch #1816: Added sys.flags structseq. It exposes the status of
6478 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006479
Georg Brandl3ee81df2008-05-17 18:14:43 +00006480- Objects/structseq.c: Implemented new structseq representation. The
6481 patch makes structseqs (e.g. the return value of os.stat) more
6482 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006483
Georg Brandl3ee81df2008-05-17 18:14:43 +00006484- Patch #1700288: added a type attribute cache that caches method
6485 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006486
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006487- Bug #1776: __import__() no longer accepts filenames on any platform.
6488 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006489
Georg Brandlaed6c662008-01-07 17:25:53 +00006490- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6491
Georg Brandl3ee81df2008-05-17 18:14:43 +00006492- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6493 envvar and sys.dont_write_bytecode attribute. All these can be set
6494 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006495
Georg Brandl3ee81df2008-05-17 18:14:43 +00006496- Improve some exception messages when Windows fails to load an
6497 extension module. Now we get for example '%1 is not a valid Win32
6498 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006499
Georg Brandl3ee81df2008-05-17 18:14:43 +00006500- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006502- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6503 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006504
Christian Heimes0a8143f2007-12-18 23:22:54 +00006505- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006506 and INF. float("nan"), float("inf") and float("-inf") now work on
6507 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006508
Georg Brandl3ee81df2008-05-17 18:14:43 +00006509- Compiler now generates simpler and faster code for dictionary
6510 literals. The oparg for BUILD_MAP now indicates an estimated
6511 dictionary size. There is a new opcode, STORE_MAP, for adding
6512 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006513
Georg Brandl3ee81df2008-05-17 18:14:43 +00006514- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00006515
Georg Brandl3ee81df2008-05-17 18:14:43 +00006516- Issue #1620: New property decorator syntax was modifying the
6517 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006518
Georg Brandl3ee81df2008-05-17 18:14:43 +00006519- Issue #1538: Avoid copying string in split/rsplit if the split char
6520 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006521
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006522- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006523 SystemError.
6524
Nick Coghlanef01d822007-12-03 12:55:17 +00006525- PEP 366: Allow explicit relative imports when executing modules
6526 inside packages with the -m switch via a new module level
6527 __package__ attribute.
6528

6530 running, and if the deallocation of its frames somehow calls the
6531 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006532

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006536 attribute of an empty cell object.
6537
Georg Brandl3ee81df2008-05-17 18:14:43 +00006538- Issue #1460: The utf-7 incremental decoder did not accept truncated
6539 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006540
Georg Brandl3ee81df2008-05-17 18:14:43 +00006541- Patch #1739468: Directories and zipfiles containing a __main__.py
6542 file can now be directly executed by passing their name to the
6543 interpreter. The directory/zipfile is automatically inserted as the
6544 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006545
Georg Brandl3ee81df2008-05-17 18:14:43 +00006546- Issue #1265: Fix a problem with sys.settrace, if the tracing
6547 function uses a generator expression when at the same time the
6548 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006549
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006550- sets and frozensets now have an isdisjoint() method.
6551
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006552- optimize the performance of builtin.sum().
6553
Neal Norwitz44f326e2007-10-05 05:29:17 +00006554- Fix warnings found by the new version of the Coverity checker.
6555
Georg Brandl21e99f42010-03-07 15:23:59 +00006556- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006557 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6558 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006559
Georg Brandl3ee81df2008-05-17 18:14:43 +00006560- Issue #1686386: Tuple's tp_repr did not take into account the
6561 possibility of having a self-referential tuple, which is possible
6562 from C code. Nor did object's tp_str consider that a type's tp_str
6563 could do something that could lead to an inifinite recursion.
6564 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6565 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006566
Georg Brandl3ee81df2008-05-17 18:14:43 +00006567- Issue #1164: It was possible to trigger deadlock when using the
6568 'print' statement to write to a file since the GIL was not released
6569 as needed. Now PyObject_Print() does the right thing along with
6570 various tp_print implementations of the built-in types and those in
6571 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006572
Georg Brandl3ee81df2008-05-17 18:14:43 +00006573- Issue #1147: Exceptions were directly allowing string exceptions in
6574 their throw() method even though string exceptions no longer
6575 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006576
Georg Brandl3ee81df2008-05-17 18:14:43 +00006577- Issue #1096: Prevent a segfault from getting the repr of a very
6578 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006579
Brett Cannon1e534b52007-09-07 04:18:30 +00006580- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006581 PyObject_Call() never calling back out to Python code to trigger
6582 recursion depth updates/checks. Required the creation of a static
6583 RuntimeError instance in case normalizing an exception put the
6584 recursion check value past its limit. Fixes crashers
6585 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006586
Georg Brandl3ee81df2008-05-17 18:14:43 +00006587- Patch #1031213: Decode source line in SyntaxErrors back to its

6591 with %G.
6592
Georg Brandl3ee81df2008-05-17 18:14:43 +00006593- Prevent expandtabs() on string and unicode objects from causing a
6594 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006595

Neal Norwitz0ac60192007-05-27 04:08:54 +00006600- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006601 __*__ attributes. (Some already existed, e.g., __doc__ and
6602 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006603
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006604- Add -3 option to the interpreter to warn about features that are
6605 deprecated and will be changed/removed in Python 3.0.
6606
Georg Brandl2134e752007-05-21 20:34:16 +00006607- Patch #1686487: you can now pass any mapping after '**' in function
6608 calls.
6609
Collin Winter62903052007-05-18 23:11:24 +00006610- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006611 "except E as target:". This is to provide forwards compatibility
6612 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006613
Brett Cannon229cee22007-05-05 01:34:02 +00006614- Deprecate BaseException.message as per PEP 352.
6615
Georg Brandl3ee81df2008-05-17 18:14:43 +00006616- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006617 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006618
Vinay Sajip8549ce32007-05-06 17:53:37 +00006619- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006620 setting a plain string, ie don't expand to single letter identifiers.
6621
Raymond Hettinger13936692007-04-11 18:40:58 +00006622- Request #1191699: Slices can now be pickled.
6623
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006624- Request #1193128: str.translate() now allows a None argument for
6625 translations that only remove characters without re-mapping the
6626 remaining characters.
6627
Georg Brandl5cb76c12007-03-21 09:00:39 +00006628- Patch #1682205: a TypeError while unpacking an iterable is no longer
6629 masked by a generic one with the message "unpack non-sequence".
6630
Neal Norwitzaa754b72007-03-21 06:39:48 +00006631- Remove unused file Python/fmod.c.
6632
Guido van Rossum143b5642007-03-23 04:58:42 +00006633- Bug #1683368: The object.__init__() and object.__new__() methods are
6634 now stricter in rejecting excess arguments. The only time when
6635 either allows excess arguments is when it is not overridden and the
6636 other one is. For backwards compatibility, when both are
6637 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006638 warning later). Also, type.__init__() insists on the same signature
6639 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006640
Georg Brandl3ee81df2008-05-17 18:14:43 +00006641- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6642 object to complex using its __complex__() method before falling back
6643 to the __float__() method. Therefore, the functions in the cmath
6644 module now can operate on objects that define a __complex__()
6645 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006646
Georg Brandl3ee81df2008-05-17 18:14:43 +00006647- Patch #1623563: allow __class__ assignment for classes with
6648 __slots__. The old and the new class are still required to have the
6649 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006650
Georg Brandl3ee81df2008-05-17 18:14:43 +00006651- Patch #1642547: Fix an error/crash when encountering syntax errors
6652 in complex if statements.

6655 ``object.__reduce_ex__()`` is called with an object that is faking
6656 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006657
Georg Brandl3ee81df2008-05-17 18:14:43 +00006658- Patch #1680015: Don't modify __slots__ tuple if it contains an

6662
Georg Brandl7b9c5552007-03-12 14:30:05 +00006663- Bug #1678647: write a newline after printing an exception in any
6664 case, even when converting the value to a string failed.
6665
Georg Brandl871f1bc2007-03-12 13:17:36 +00006666- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006667 its argument, if it exists. If not, it will work like before. This
6668 allows customizing the output of dir() in the presence of a
6669 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006670
Collin Winter276887b2007-03-12 16:11:39 +00006671- Patch #922167: Python no longer segfaults when faced with infinitely
6672 self-recursive reload() calls (as reported by bug #742342).
6673
Georg Brandl3ee81df2008-05-17 18:14:43 +00006674- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00006677- Patch #1491866: change the complex() constructor to allow
6678 parthensized forms. This means complex(repr(x)) now works instead of
6679 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006680
Georg Brandlaa2321b2007-03-07 00:40:28 +00006681- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006682 makes the filenames the warning module prints much more sensible
6683 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006684
Georg Brandl49aafc92007-03-07 00:34:46 +00006685- Variant of patch #697613: don't exit the interpreter on a SystemExit
6686 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006687 variable is given, but break into the interactive interpreter just
6688 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00006695
Georg Brandl0fca97a2007-03-05 22:28:08 +00006696- Patch #1674228: when assigning a slice (old-style), check for the
6697 sq_ass_slice instead of the sq_slice slot.
6698
Georg Brandl3ee81df2008-05-17 18:14:43 +00006699- When printing an unraisable error, don't print exceptions. before
6700 the name. This duplicates the behavior whening normally printing
6701 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00006702
Georg Brandl3ee81df2008-05-17 18:14:43 +00006703- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007203- Added a timeout parameter to the constructor of other protocols
7204 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7205 work started with create_connection() and timeout in httplib, and
7206 closes patch #723312.
7207
Vinay Sajip8549ce32007-05-06 17:53:37 +00007208- Patch #1676823: Added create_connection() to socket.py, which may be
7209 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007210 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007211
Martin v. Löwis0af33882007-03-23 13:27:15 +00007212- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007219- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
7220 to True (which is not the default), it visits symlinks pointing to

7224 GNOME or KDE browser, depending on whether there is a session of one
7225 of those present. Also, it tries the Windows default browser before
7226 trying Mozilla variants.

7232
Georg Brandlf66b6032007-03-14 08:27:52 +00007233- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007234 AttributeError instead of an IOError when the server's response
7235 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007236
Georg Brandl3ee81df2008-05-17 18:14:43 +00007237- Patch #957650: "%var%" environment variable references are now
7238 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00007240
Georg Brandl3ee81df2008-05-17 18:14:43 +00007241- Patch #1429539: pdb now correctly initializes the __main__ module
7242 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007243 correctly now.
7244
Georg Brandlbad6f192007-03-13 21:32:56 +00007245- The nonobvious commands.getstatus() function is now deprecated.

7251
Georg Brandl3ee81df2008-05-17 18:14:43 +00007252- Patch #1530482: add pydoc.render_doc() which returns the
7253 documentation for a thing instead of paging it to stdout, which
7254 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00007255

7262 parameter which can be set to False to prevent the default
7263 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00007264
Georg Brandl9e6b4702007-03-13 18:15:41 +00007265- Patch #1581073: add a flag to textwrap that prevents the dropping of
7266 whitespace while wrapping.
7267
Georg Brandl92a6bae2007-03-13 17:43:32 +00007268- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007269 are set for invalid interpolation sequences that would lead to
7270 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007271

7284
Georg Brandl94fe3f52007-03-13 09:32:11 +00007285- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00007286 field names in its exception message if you try to write a record
7287 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00007305

7313 returned string up to the first NUL character.
7314

7324
Georg Brandl3ee81df2008-05-17 18:14:43 +00007325- unittest now verifies more of its assumptions. In particular,
7326 TestCase and TestSuite subclasses (not instances) are no longer
7327 accepted in TestSuite.addTest(). This should cause no
7328 incompatibility since it never made sense with ordinary subclasses
7329 -- the failure just occurred later, with a more cumbersome
7330 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00007331

7339 given a unicode argument and os.listdir() returns unicode filenames.
7340
Georg Brandl3ee81df2008-05-17 18:14:43 +00007341- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00007719 time so that opening a database previously created with the DB_DUP
7720 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7721 opens. Specifically: dictionary assignment to a DB object will
7722 replace all values for a given key when the database allows
7723 duplicate values. DB users should use DB.put(k, v) when they want
7724 to store duplicates; not DB[k] = v.

7731 characters with ASCII value less than 32. Also, it correctly quotes
7732 dots only if they occur on a single line, as opposed to the previous
7733 behavior of quoting dots if they are the second character of any
7734 line.
