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

1155 of the number of bytes specified by the start byte.
1156 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1157 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1169 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

1537-----------------
1538
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001539- Issue #7301: Add environment variable $PYTHONWARNINGS.
1540
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001541- Issue #8329: Don't return the same lists from select.select when no fds are
1542 changed.
1543
Georg Brandlfee0f442010-05-22 21:26:21 +00001544- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001545 on 64-bit machines. The shift count for either left or right shift is
1546 permitted to be up to sys.maxsize.
1547
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001548- Ensure that tokenization of identifiers is not affected by locale.

1553
Georg Brandlfee0f442010-05-22 21:26:21 +00001554- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1555 with a non-empty format string. This is an effort to future-proof user
1556 code. If a derived class does not currently implement __format__ but later
1557 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001558 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001559 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001592- Issue #8257: The Decimal construct now accepts a float instance directly,
1593 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001594

1597
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001598- collections.Counter() now supports a subtract() method.
1599
Georg Brandlfee0f442010-05-22 21:26:21 +00001600- The functools module now has a total_ordering() class decorator to simplify
1601 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00001609- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1610 InvalidOperation instead of returning False. (Comparisons involving a quiet
1611 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1612 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001613
Georg Brandlfee0f442010-05-22 21:26:21 +00001614- Issue #2531: Comparison operations between floats and Decimal instances now
1615 return a result based on the numeric values of the operands; previously they
1616 returned an arbitrary result based on the relative ordering of id(float) and
1617 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001618
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001619- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001620 argument `-` which tells it to read files to compile from stdin. Each line is
1621 read on demand and the named file is compiled immediately. (Original patch by
1622 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00001631- Comparisons using one of <, <=, >, >= between a complex instance and a
1632 Fractions instance now raise TypeError instead of returning True/False. This
1633 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1634 <=> complex, and complex <=> complex comparisons.

1743 the set of integer codes for which it was used differed between native packing
1744 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002052 file position when calling `truncate()`. It would previously change the file
2053 position to the given argument, which goes against the tradition of

Mark Dickinson1b34d252010-01-01 17:27:30 +00002157- Issue #5080: A number of functions and methods previously produced a

2159 These functions and methods now raise TypeError instead. The majority of the
2160 effects of this change are in the extension modules, but some core functions
2161 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2162 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002345- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2346 decimal string that's guaranteed to round back to x under correct rounding
2347 (with round-half-to-even rounding mode). Previously it gave a string based on
2348 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2349 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2350 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002351
Georg Brandlba83f822010-03-14 09:50:54 +00002352- Issue #7117: On almost all platforms: float-to-string and string-to-float
2353 conversions within Python are now correctly rounded. Places these conversions
2354 occur include: str for floats and complex numbers; the float and complex
2355 constructors; old-style and new-style numeric formatting; serialization and
2356 deserialization of floats and complex numbers using marshal, pickle and json;
2357 parsing of float and imaginary literals in Python code; Decimal-to-float
2358 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002359
Georg Brandlba83f822010-03-14 09:50:54 +00002360 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2361 providing correctly-rounded strtod and dtoa C functions. This code is
2362 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2363 the C compiler. There may be a small number of platforms on which correct
2364 operation of this code cannot be guaranteed, so the code is not used: notably,
2365 this applies to platforms where the C double format is not IEEE 754 binary64,
2366 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2367 and Python's configure script is unable to determine how to change the FPU
2368 precision. On these platforms conversions use the platform strtod and dtoa,
2369 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002371- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2372 uses the correctly-rounded string <-> float conversions described above (when
2373 available), and so produces correctly rounded results that will display nicely
2374 under the float repr. There are two related small changes: (1) round now
2375 accepts any class with an ``__index__()`` method for its second argument (but
2376 no longer accepts floats for the second argument), and (2) an excessively
2377 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2378 raises an exception.

2757 this code path is really executed because I cannot move to such directory on

2784 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

4160
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004161- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4162 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4163 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4164 ``printf`` function, whereas PyString_FromFormat has an independent
4165 implementation and uses "%zd" on all platforms for size_t values.
4166 This makes a difference on win64, where ``printf`` needs "%Id" to display
4167 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00004187 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4188 mechanism. In the process, fix a bug where isinstance() and issubclass(),

4190 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4191 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004262 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4263 for catch_warnings() also led to an improvement in the raising of a
4264 DeprecationWarning related to warnings.warn_explicit().
4265
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004266- The deprecation warnings for the old camelCase threading API were removed.

4288
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004289- Issue #2975: When compiling several extension modules with Visual Studio 2008
4290 from the same python interpreter, some environment variables would grow
4291 without limit.
4292
Benjamin Peterson37346b22008-08-23 20:27:43 +00004293- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4294 exploitation of poor argument checking.
4295
Gerhard Häringef2276b2008-09-12 13:54:06 +00004296- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

4309 wrapper for warnings.catch_warnings() that makes it easier to check
4310 that expected warning messages are being reported.
4311

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004330What's New in Python 2.6 beta 3?
4331================================
4332
Barry Warsaw07a4a382008-08-21 01:15:08 +00004333*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004334
4335Core and Builtins
4336-----------------
4337
Guido van Rossumf8402962008-08-20 15:01:50 +00004338- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4339 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4340 extensions do not automatically benefit from the class attribute
4341 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4342 to their tp_flags field if they care. This is a backwards
4343 compatibility feature; in 3.0, all types will use the cache by
4344 default.
4345
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004346- Keyword arguments can now follow starred arguments. (``f(a, *args,
4347 keyword=23)`` is now valid syntax.)
4348
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004349- ctypes function pointers that are COM methods have a boolean True
4350 value again.
4351
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004352- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4353 by denying s# to parse objects that have a releasebuffer procedure,
4354 and introducing s*.
4355
Georg Brandl1e13ea92008-08-11 09:07:59 +00004356- Issue #3537: Fix an assertion failure when an empty but presized dict
4357 object was stored in the freelist.
4358
Mark Dickinsonb6467572008-08-04 21:30:09 +00004359- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4360 ValueError consistently across platforms.
4361
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004362- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4363 (64bit Unix, for example), unichr() would truncate its argument and return
4364 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4365
Neal Norwitze7d8be82008-07-31 17:17:14 +00004366- Apply security patches from Apple.
4367
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004368- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4369 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4370
Antoine Pitrou92f82162008-07-25 22:22:08 +00004371- Issue #1819: function calls with several named parameters are now on
4372 average 35% faster (as measured by pybench).
4373
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004374- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4375 the python debugger steps into a class statement: the free variables (local
4376 variables defined in an outer scope) would be deleted from the outer scope.
4377
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004378- Issue #2620: Overflow checking when allocating or reallocating memory
4379 was not always being done properly in some python types and extension
4380 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4381 all been updated to perform better checks and places in the code that
4382 would previously leak memory on the error path when such an allocation
4383 failed have been fixed.

4386-------
4387
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004388- Issue #3612: Added some missing basic types in ctypes.wintypes.
4389
Benjamin Petersone977ad42008-08-20 01:42:01 +00004390- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4391 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4392
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004393- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4394 version reported by these tools does not necessarily follow the python
4395 version numbering scheme, so the module is less strict when parsing it.
4396
Nick Coghlanf70385a2008-08-18 12:42:46 +00004397- Issue #2235: Added Py3k warnings for types which will become unhashable
4398 under the stricter __hash__ inheritance rules in 3.0. Several types
4399 which did not meet the rules for hash invariants and were already
4400 unhashable in 3.0 have now been explicitly flagged as unhashable in
4401 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4402 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4403
Brett Cannon88f801d2008-08-18 00:46:22 +00004404- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4405 imported into the module but exposed as part of the module's API.
4406
Brett Cannon7b96f072008-08-18 00:41:11 +00004407- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4408
Brett Cannon46225e72008-08-18 00:36:52 +00004409- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004411- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4412
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004413- Issue #3575: Incremental decoder's decode function now takes bytearray
4414 by using 's*' instead of 't#'.
4415
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004416- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004417 fails unicode conversion on 2nd parameter. (windows only)
4418
Georg Brandl222e2082010-08-01 22:27:39 +00004419- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004420 in a redirect.
4421
Brett Cannonabe423e2008-08-16 21:47:07 +00004422- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004423 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004424
Facundo Batistaeb90b782008-08-16 14:44:07 +00004425- Issue #2776: fixed small issue when handling an URL with double slash
4426 after a 302 response in the case of not going through a proxy.
4427
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004428- Issue #2676: in the email package, content-type parsing was hanging on
4429 pathological input because of quadratic or exponential behaviour of a
4430 regular expression.
4431
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004432- Issue #3476: binary buffered reading through the new "io" library is now
4433 thread-safe.
4434
Brett Cannonbf3157b2008-08-14 05:00:03 +00004435- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4436 since mimetools itself is deprecated. Because modules are cached, all
4437 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4438
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004439- Issue #3134: shutil referenced undefined WindowsError symbol.
4440
Robert Schuppenies14646332008-08-10 11:01:53 +00004441- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4442 menu entries were not deleted.
4443
Brett Cannon83e81842008-08-09 23:30:55 +00004444- Copied the implementation of reduce() to _functools.reduce() to have a
4445 version that did not raise a DeprecationWarning under -3.
4446
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004447- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4448 a MemoryError rather than silently stop the iteration.
4449
Guido van Rossum59ce9012008-08-09 14:55:34 +00004450- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4451 to _sre.compile() will now be rejected. This should not affect anybody
4452 since the re.compile() function never generates invalid re-bytecode.
4453
Skip Montanaroa032bf42008-08-08 22:52:51 +00004454- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4455 upon first access it can be automatically initialized from the csv file if
4456 it wasn't initialized during instantiation.
4457
Brett Cannon3aa2a492008-08-06 22:28:09 +00004458- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4459 the reload() built-in has been removed.
4460
Brett Cannon7e30b672008-08-04 21:52:25 +00004461- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004462 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004473 asking for a specific length. This problem only affected files opened
4474 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004475

4500 file name rather than a ZipInfo instance, so files are extracted with
4501 mode 0600 rather than 000 under Unix.
4502
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004503- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4504 argument in python 2.5, this broke code that subclassed Popen to include its
4505 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4520 regarding lack of coverage of new-style classes have also been
4521 removed, since the coverage is now fairly reasonable.

4531
Georg Brandl3e483f62008-07-16 22:57:41 +00004532- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4533 its methods now allow for items objects that can be converted to
4534 an integer using operator.index().
4535
Mark Dickinson64b7e502008-07-16 09:40:03 +00004536- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4537 produced a ValueError instead of giving the correct float.
4538
Eric Smitha5fa5a22008-07-16 00:11:49 +00004539- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4540 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4541
Mark Dickinson7103aa42008-07-15 19:08:33 +00004542- Issue #3008: the float type has a new instance method 'float.hex'
4543 and a new class method 'float.fromhex' to convert floating-point
4544 numbers to and from hexadecimal strings, respectively.
4545
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004546- Issue #2235: __hash__ is once again inherited by default. To allow
4547 collections.Hashable to remain meaningful in the presence of the
4548 default hash implementation (object.__hash__), it is now possible
4549 to explicit block inheritance of hash by setting __hash__=None at
4550 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4551 level.
4552
Nick Coghlanb028f502008-07-13 14:52:36 +00004553- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4554 the parent module cannot be found while performing an absolute import.
4555 This means that an incorrectly defined __package__ attribute will
4556 now only prevent relative imports in that module rather than causing
4557 all imports from that module to fail.
4558
Nick Coghlan14ff9942008-07-08 14:21:42 +00004559- Issue #2517: Allow unicode messages in Exceptions again by correctly

4570
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004571- Issue #3004: Minor change to slice.indices(): the start and stop
4572 arguments are now treated identically, making the behaviour easier
4573 to describe and understand. For example, slice(None, -10,
4574 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4575 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4576 10, -1).

4619 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004620 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005092- Issue #1631171: Re-implement the 'warnings' module in C (the
5093 original Python code has been kept as backup). This will allow for
5094 using the 'warning's machinery in such places as the parser where
5095 use of pure Python code is not possible. Both the ``showarning()``
5096 and ``formatwarning()`` gain an optional 'line' argument which is

Georg Brandl3ee81df2008-05-17 18:14:43 +00005162- Issue #2550: The approach used by client/server code for obtaining
5163 ports to listen on in network-oriented tests has been refined in an
5164 effort to facilitate running multiple instances of the entire
5165 regression test suite in parallel without issue.
5166 test_support.bind_port() has been fixed such that it will always
5167 return a unique port -- which wasn't always the case with the
5168 previous implementation, especially if socket options had been set
5169 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5170 new implementation of bind_port() will actually raise an exception
5171 if it is passed an AF_INET/SOCK_STREAM socket with either the
5172 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5173 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5174 the socket it's been passed. This currently only applies to
5175 Windows. This option prevents any other sockets from binding to the
5176 host/port we've bound to, thus removing the possibility of the
5177 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5178 when a second SOCK_STREAM socket binds and accepts to a host/port
5179 that's already been bound by another socket. The optional preferred
5180 port parameter to bind_port() has been removed. Under no
5181 circumstances should tests be hard coding ports!
5182
5183 test_support.find_unused_port() has also been introduced, which will
5184 pass a temporary socket object to bind_port() in order to obtain an
5185 unused port. The temporary socket object is then closed and
5186 deleted, and the port is returned. This method should only be used
5187 for obtaining an unused port in order to pass to an external program
5188 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5189 a parameter to a server-oriented class that doesn't give you direct
5190 access to the underlying socket used.
5191
5192 Finally, test_support.HOST has been introduced, which should be used
5193 for the host argument of any relevant socket calls (i.e. bind and
5194 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005195
5196 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005197 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005198 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5199 test_asynchat and test_socket_ssl.
5200
Georg Brandl3ee81df2008-05-17 18:14:43 +00005201 It is now possible for multiple instances of the regression test
5202 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005368- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
5369 values on 32-bit vs. 64-bit python interpreters. Both were correct,
5370 but they now both return a signed integer object for consistency.

Eric Smitha73fbe72008-02-23 03:09:44 +00005481- Added the future_builtins module, which contains hex() and oct().
5482 These are the PEP 3127 version of these functions, designed to be
5483 compatible with the hex() and oct() builtins from Python 3.0. They
5484 differ slightly in their output formats from the existing, unchanged
5485 Python 2.6 builtins. The expected usage of the future_builtins
5486 module is:
5487 from future_builtins import hex, oct
5488
Eric Smith7ef40bf2008-02-20 23:34:22 +00005489- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5490 exponents for exponents with absolute value < 100. Follows C99
5491 standard. This is a change on Windows, which would use 3 digits.
5492 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5493 so that any alterations it does to the resulting string will be
5494 available in stringlib/formatter.h (for float.__format__).
5495
Eric Smith5a3c1352008-02-19 13:21:56 +00005496- Implemented PEP 3101, Advanced String Formatting. This adds a new
5497 builtin format(); a format() method for str and unicode; a
5498 __format__() method to object, str, unicode, int, long, float, and
5499 datetime; the class string.Formatter; and the C API
5500 PyObject_Format().
5501
Georg Brandl3ee81df2008-05-17 18:14:43 +00005502- Fixed several potential crashes, all caused by specially crafted
5503 __del__ methods exploiting objects in temporarily inconsistent
5504 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005505
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005506- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005507 prevent a possible crash: an Abstract Base Class would try to access
5508 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005509

Georg Brandl3ee81df2008-05-17 18:14:43 +00005513- Clear all free lists during a gc.collect() of the highest generation
5514 in order to allow pymalloc to free more arenas. Python may give back
5515 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005516
Georg Brandl3ee81df2008-05-17 18:14:43 +00005517- Issue #2045: Fix an infinite recursion triggered when printing a
5518 subclass of collections.defaultdict, if its default_factory is set
5519 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005520
Christian Heimesf75dbef2008-02-08 00:11:31 +00005521- Fixed a minor memory leak in dictobject.c. The content of the free
5522 list was not freed on interpreter shutdown.
5523
Georg Brandl21e99f42010-03-07 15:23:59 +00005524- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005525 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005526
Georg Brandl3ee81df2008-05-17 18:14:43 +00005527- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5528 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005529 to compact the internal free lists of pre-allocted ints and floats.
5530
Georg Brandl3ee81df2008-05-17 18:14:43 +00005531- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5532 calls. Python expected the return type int but the fork familie
5533 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005534
Georg Brandl3ee81df2008-05-17 18:14:43 +00005535- Issue #1678380: Fix a bug that identifies 0j and -0j when they

5545 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005546
Georg Brandl3ee81df2008-05-17 18:14:43 +00005547- Patch #1473257: generator objects gain a gi_code attribute. This is
5548 the same object as the func_code attribute of the function that
5549 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005550
Georg Brandl3ee81df2008-05-17 18:14:43 +00005551- Issue #1920: "while 0" statements were completely removed by the
5552 compiler, even in the presence of an "else" clause, which is
5553 supposed to be run when the condition is false. Now the compiler
5554 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005555
Guido van Rossumeead05f2008-01-24 18:21:02 +00005556- A few crashers fixed: weakref_in_del.py (issue #1377858);
5557 loosing_dict_ref.py (issue #1303614, test67.py);
5558 borrowed_ref_[34].py (not in tracker).
5559
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005560- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005561 suppressed while an extension is loaded by calling SetErrorMode in

5563
Georg Brandl3ee81df2008-05-17 18:14:43 +00005564- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005565 several extension methods and modules do not work without unicode
5566 support.
5567
Georg Brandl26543b12008-01-21 18:36:51 +00005568- Issue #1882: when compiling code from a string, encoding cookies in the
5569 second line of code were not always recognized correctly.
5570
Georg Brandl14404b62008-01-19 19:27:05 +00005571- Issue #1679: "0x" was taken as a valid integer literal.
5572
Georg Brandl6caad7d2008-01-26 14:19:22 +00005573- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005574 added.
5575
Christian Heimesc94e2b52008-01-14 04:13:37 +00005576- sys.float_info / PyFloat_GetInfo: The floating point information
5577 object was converted from a dict to a specialized structseq object.
5578
Georg Brandl3ee81df2008-05-17 18:14:43 +00005579- Patch #1816: Added sys.flags structseq. It exposes the status of
5580 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005581
Georg Brandl3ee81df2008-05-17 18:14:43 +00005582- Objects/structseq.c: Implemented new structseq representation. The
5583 patch makes structseqs (e.g. the return value of os.stat) more
5584 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005585
Georg Brandl3ee81df2008-05-17 18:14:43 +00005586- Patch #1700288: added a type attribute cache that caches method

5595 envvar and sys.dont_write_bytecode attribute. All these can be set
5596 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005597
Georg Brandl3ee81df2008-05-17 18:14:43 +00005598- Improve some exception messages when Windows fails to load an
5599 extension module. Now we get for example '%1 is not a valid Win32

Georg Brandl3ee81df2008-05-17 18:14:43 +00005608 and INF. float("nan"), float("inf") and float("-inf") now work on
5609 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005611- Compiler now generates simpler and faster code for dictionary
5612 literals. The oparg for BUILD_MAP now indicates an estimated
5613 dictionary size. There is a new opcode, STORE_MAP, for adding
5614 entries to the dictionary.

5626
Nick Coghlanef01d822007-12-03 12:55:17 +00005627- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005643- Patch #1739468: Directories and zipfiles containing a __main__.py
5644 file can now be directly executed by passing their name to the
5645 interpreter. The directory/zipfile is automatically inserted as the
5646 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005647
Georg Brandl3ee81df2008-05-17 18:14:43 +00005648- Issue #1265: Fix a problem with sys.settrace, if the tracing
5649 function uses a generator expression when at the same time the
5650 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005651
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005652- sets and frozensets now have an isdisjoint() method.

5657
Georg Brandl21e99f42010-03-07 15:23:59 +00005658- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005659 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5660 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005661
Georg Brandl3ee81df2008-05-17 18:14:43 +00005662- Issue #1686386: Tuple's tp_repr did not take into account the
5663 possibility of having a self-referential tuple, which is possible
5664 from C code. Nor did object's tp_str consider that a type's tp_str
5665 could do something that could lead to an inifinite recursion.
5666 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5667 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005668
Georg Brandl3ee81df2008-05-17 18:14:43 +00005669- Issue #1164: It was possible to trigger deadlock when using the
5670 'print' statement to write to a file since the GIL was not released
5671 as needed. Now PyObject_Print() does the right thing along with
5672 various tp_print implementations of the built-in types and those in
5673 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005674
Georg Brandl3ee81df2008-05-17 18:14:43 +00005675- Issue #1147: Exceptions were directly allowing string exceptions in
5676 their throw() method even though string exceptions no longer
5677 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005678
Georg Brandl3ee81df2008-05-17 18:14:43 +00005679- Issue #1096: Prevent a segfault from getting the repr of a very
5680 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005681
Brett Cannon1e534b52007-09-07 04:18:30 +00005682- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005683 PyObject_Call() never calling back out to Python code to trigger
5684 recursion depth updates/checks. Required the creation of a static
5685 RuntimeError instance in case normalizing an exception put the
5686 recursion check value past its limit. Fixes crashers
5687 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005688
Georg Brandl3ee81df2008-05-17 18:14:43 +00005689- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005702- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005703 __*__ attributes. (Some already existed, e.g., __doc__ and
5704 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005705
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005706- Add -3 option to the interpreter to warn about features that are
5707 deprecated and will be changed/removed in Python 3.0.
5708
Georg Brandl2134e752007-05-21 20:34:16 +00005709- Patch #1686487: you can now pass any mapping after '**' in function
5710 calls.
5711
Collin Winter62903052007-05-18 23:11:24 +00005712- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005713 "except E as target:". This is to provide forwards compatibility
5714 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005715
Brett Cannon229cee22007-05-05 01:34:02 +00005716- Deprecate BaseException.message as per PEP 352.
5717
Georg Brandl3ee81df2008-05-17 18:14:43 +00005718- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005719 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005720
Vinay Sajip8549ce32007-05-06 17:53:37 +00005721- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005722 setting a plain string, ie don't expand to single letter identifiers.
5723
Raymond Hettinger13936692007-04-11 18:40:58 +00005724- Request #1191699: Slices can now be pickled.
5725
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005726- Request #1193128: str.translate() now allows a None argument for
5727 translations that only remove characters without re-mapping the
5728 remaining characters.
5729
Georg Brandl5cb76c12007-03-21 09:00:39 +00005730- Patch #1682205: a TypeError while unpacking an iterable is no longer
5731 masked by a generic one with the message "unpack non-sequence".
5732
Neal Norwitzaa754b72007-03-21 06:39:48 +00005733- Remove unused file Python/fmod.c.
5734
Guido van Rossum143b5642007-03-23 04:58:42 +00005735- Bug #1683368: The object.__init__() and object.__new__() methods are
5736 now stricter in rejecting excess arguments. The only time when
5737 either allows excess arguments is when it is not overridden and the
5738 other one is. For backwards compatibility, when both are
5739 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005740 warning later). Also, type.__init__() insists on the same signature
5741 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005742
Georg Brandl3ee81df2008-05-17 18:14:43 +00005743- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5744 object to complex using its __complex__() method before falling back
5745 to the __float__() method. Therefore, the functions in the cmath
5746 module now can operate on objects that define a __complex__()
5747 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005748
Georg Brandl3ee81df2008-05-17 18:14:43 +00005749- Patch #1623563: allow __class__ assignment for classes with
5750 __slots__. The old and the new class are still required to have the
5751 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005752
Georg Brandl3ee81df2008-05-17 18:14:43 +00005753- Patch #1642547: Fix an error/crash when encountering syntax errors

5757 ``object.__reduce_ex__()`` is called with an object that is faking
5758 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005759
Georg Brandl3ee81df2008-05-17 18:14:43 +00005760- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00005763- Patch #1444529: the builtin compile() now accepts keyword arguments.
5764
Georg Brandl7b9c5552007-03-12 14:30:05 +00005765- Bug #1678647: write a newline after printing an exception in any
5766 case, even when converting the value to a string failed.
5767
Georg Brandl871f1bc2007-03-12 13:17:36 +00005768- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005769 its argument, if it exists. If not, it will work like before. This
5770 allows customizing the output of dir() in the presence of a
5771 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005772
Collin Winter276887b2007-03-12 16:11:39 +00005773- Patch #922167: Python no longer segfaults when faced with infinitely
5774 self-recursive reload() calls (as reported by bug #742342).
5775
Georg Brandl3ee81df2008-05-17 18:14:43 +00005776- Patch #1675981: remove unreachable code from ``type.__new__()``
5777 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005779- Patch #1491866: change the complex() constructor to allow
5780 parthensized forms. This means complex(repr(x)) now works instead of
5781 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005782
Georg Brandlaa2321b2007-03-07 00:40:28 +00005783- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005784 makes the filenames the warning module prints much more sensible
5785 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005786
Georg Brandl49aafc92007-03-07 00:34:46 +00005787- Variant of patch #697613: don't exit the interpreter on a SystemExit
5788 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005789 variable is given, but break into the interactive interpreter just
5790 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00005797
Georg Brandl0fca97a2007-03-05 22:28:08 +00005798- Patch #1674228: when assigning a slice (old-style), check for the
5799 sq_ass_slice instead of the sq_slice slot.
5800
Georg Brandl3ee81df2008-05-17 18:14:43 +00005801- When printing an unraisable error, don't print exceptions. before
5802 the name. This duplicates the behavior whening normally printing
5803 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006354- Patch #1530482: add pydoc.render_doc() which returns the

6369
Georg Brandl92a6bae2007-03-13 17:43:32 +00006370- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006371 are set for invalid interpolation sequences that would lead to
6372 errors on reading back those values.

6428 TestCase and TestSuite subclasses (not instances) are no longer
6429 accepted in TestSuite.addTest(). This should cause no
6430 incompatibility since it never made sense with ordinary subclasses
6431 -- the failure just occurred later, with a more cumbersome
6432 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006719 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00006721 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006820- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006821 time so that opening a database previously created with the DB_DUP
6822 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6823 opens. Specifically: dictionary assignment to a DB object will
6824 replace all values for a given key when the database allows
6825 duplicate values. DB users should use DB.put(k, v) when they want
6826 to store duplicates; not DB[k] = v.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007105- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007106 periodic threadstate and signal checking in tight loops. By
7107 default, this option is turned-off. It should only be enabled in

Georg Brandl3ee81df2008-05-17 18:14:43 +00007166- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7167 to ``PyTuple_SetItem``, it can be used to populate a brand new

7182 of w# format code incorrectly truncated the length to an int, even
7183 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7184 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007214- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7215 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
