Ezio Melottiab2eb0e2010-06-05 19:21:32 +000060- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
61 start byte and the continuation byte(s) are now considered invalid, instead
62 of the number of bytes specified by the start byte.
63 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
64 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
65 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
66 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +000068- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +000069 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
70 arises from the "Overriding __eq__ blocks inheritance ..." warning
71 when turned into an exception: in this case the exception simply
72 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +000073
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +000074- Issue #8748: Fix two issues with comparisons between complex and integer
75 objects. (1) The comparison could incorrectly return True in some cases
76 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
77 (2) The comparison raised an OverflowError for large integers, leading
78 to unpredictable exceptions when combining integers and complex objects
79 in sets or dicts.
80
Mark Dickinson81336372010-05-30 12:12:25 +000081- Issue #5211: Implicit coercion for the complex type is now completely
82 removed. (Coercion for arithmetic operations was already removed in 2.7
83 alpha 4, but coercion for rich comparisons was accidentally left in.)
84
Victor Stinnerc49dfcc2010-05-25 22:30:32 +000085- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
86 and error handler, instead of writing to the C stderr file in utf-8
87
Georg Brandlfee0f442010-05-22 21:26:21 +000088- Issue #7902: When using explicit relative import syntax, don't try implicit
89 relative import semantics.

447
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000448- Issue #8329: Don't return the same lists from select.select when no fds are
449 changed.

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

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000526- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000527 argument `-` which tells it to read files to compile from stdin. Each line is
528 read on demand and the named file is compiled immediately. (Original patch by

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000948- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000949 file position when calling `truncate()`. It would previously change the file
950 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000951 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

956 class used to represent files stored inside an archive. The new
957 implementation is significantly faster and can be wrapped in a
958 ``io.BufferedReader`` object for more speedups. It also solves an issue
959 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001050- The ``__complex__()`` method is now looked up on the class of instances to
1051 make it consistent with other special methods.

1055
Mark Dickinson1b34d252010-01-01 17:27:30 +00001056- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001057 DeprecationWarning when passed a float argument where an integer was expected.
1058 These functions and methods now raise TypeError instead. The majority of the
1059 effects of this change are in the extension modules, but some core functions
1060 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1061 and many unicode/str methods.

1075 of integers: the result of a/b is now correctly rounded for ints a and b (at
1076 least on IEEE 754 platforms), and in particular does not depend on the
1077 internal representation of a long.

1085
Georg Brandlba83f822010-03-14 09:50:54 +00001086 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00001244- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1245 decimal string that's guaranteed to round back to x under correct rounding
1246 (with round-half-to-even rounding mode). Previously it gave a string based on
1247 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1248 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1249 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001251- Issue #7117: On almost all platforms: float-to-string and string-to-float
1252 conversions within Python are now correctly rounded. Places these conversions
1253 occur include: str for floats and complex numbers; the float and complex
1254 constructors; old-style and new-style numeric formatting; serialization and
1255 deserialization of floats and complex numbers using marshal, pickle and json;
1256 parsing of float and imaginary literals in Python code; Decimal-to-float
1257 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001258
Georg Brandlba83f822010-03-14 09:50:54 +00001259 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1260 providing correctly-rounded strtod and dtoa C functions. This code is
1261 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1262 the C compiler. There may be a small number of platforms on which correct
1263 operation of this code cannot be guaranteed, so the code is not used: notably,
1264 this applies to platforms where the C double format is not IEEE 754 binary64,
1265 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1266 and Python's configure script is unable to determine how to change the FPU
1267 precision. On these platforms conversions use the platform strtod and dtoa,
1268 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001270- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1271 uses the correctly-rounded string <-> float conversions described above (when
1272 available), and so produces correctly rounded results that will display nicely
1273 under the float repr. There are two related small changes: (1) round now
1274 accepts any class with an ``__index__()`` method for its second argument (but
1275 no longer accepts floats for the second argument), and (2) an excessively
1276 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1277 raises an exception.

2860 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2861 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003060- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3061 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3062 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3063 ``printf`` function, whereas PyString_FromFormat has an independent
3064 implementation and uses "%zd" on all platforms for size_t values.

3161 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3162 for catch_warnings() also led to an improvement in the raising of a
3163 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003229What's New in Python 2.6 beta 3?
3230================================
3231
Barry Warsaw07a4a382008-08-21 01:15:08 +00003232*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003233
3234Core and Builtins
3235-----------------
3236
Guido van Rossumf8402962008-08-20 15:01:50 +00003237- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3238 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3239 extensions do not automatically benefit from the class attribute
3240 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3241 to their tp_flags field if they care. This is a backwards
3242 compatibility feature; in 3.0, all types will use the cache by
3243 default.
3244
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003245- Keyword arguments can now follow starred arguments. (``f(a, *args,
3246 keyword=23)`` is now valid syntax.)
3247
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003248- ctypes function pointers that are COM methods have a boolean True
3249 value again.
3250
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003251- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3252 by denying s# to parse objects that have a releasebuffer procedure,
3253 and introducing s*.
3254
Georg Brandl1e13ea92008-08-11 09:07:59 +00003255- Issue #3537: Fix an assertion failure when an empty but presized dict
3256 object was stored in the freelist.
3257
Mark Dickinsonb6467572008-08-04 21:30:09 +00003258- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3259 ValueError consistently across platforms.
3260
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003261- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3262 (64bit Unix, for example), unichr() would truncate its argument and return
3263 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3264
Neal Norwitze7d8be82008-07-31 17:17:14 +00003265- Apply security patches from Apple.
3266
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003267- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3268 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3269
Antoine Pitrou92f82162008-07-25 22:22:08 +00003270- Issue #1819: function calls with several named parameters are now on
3271 average 35% faster (as measured by pybench).
3272
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003273- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3274 the python debugger steps into a class statement: the free variables (local
3275 variables defined in an outer scope) would be deleted from the outer scope.
3276
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003277- Issue #2620: Overflow checking when allocating or reallocating memory
3278 was not always being done properly in some python types and extension
3279 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3280 all been updated to perform better checks and places in the code that
3281 would previously leak memory on the error path when such an allocation
3282 failed have been fixed.

3286
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003287- Issue #3612: Added some missing basic types in ctypes.wintypes.
3288
Benjamin Petersone977ad42008-08-20 01:42:01 +00003289- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3290 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3291
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003292- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3293 version reported by these tools does not necessarily follow the python
3294 version numbering scheme, so the module is less strict when parsing it.
3295
Nick Coghlanf70385a2008-08-18 12:42:46 +00003296- Issue #2235: Added Py3k warnings for types which will become unhashable
3297 under the stricter __hash__ inheritance rules in 3.0. Several types
3298 which did not meet the rules for hash invariants and were already
3299 unhashable in 3.0 have now been explicitly flagged as unhashable in
3300 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3301 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3302
Brett Cannon88f801d2008-08-18 00:46:22 +00003303- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3304 imported into the module but exposed as part of the module's API.
3305
Brett Cannon7b96f072008-08-18 00:41:11 +00003306- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3307
Brett Cannon46225e72008-08-18 00:36:52 +00003308- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003310- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3311
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003312- Issue #3575: Incremental decoder's decode function now takes bytearray
3313 by using 's*' instead of 't#'.
3314
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003315- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003316 fails unicode conversion on 2nd parameter. (windows only)
3317
Facundo Batista94f243a2008-08-17 03:38:39 +00003318- Issue 2464. urllib2 now supports a malformation in the URL received
3319 in a redirect.
3320
Brett Cannonabe423e2008-08-16 21:47:07 +00003321- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003322 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003323
Facundo Batistaeb90b782008-08-16 14:44:07 +00003324- Issue #2776: fixed small issue when handling an URL with double slash
3325 after a 302 response in the case of not going through a proxy.
3326
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003327- Issue #2676: in the email package, content-type parsing was hanging on
3328 pathological input because of quadratic or exponential behaviour of a
3329 regular expression.
3330
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003331- Issue #3476: binary buffered reading through the new "io" library is now
3332 thread-safe.
3333
Brett Cannonbf3157b2008-08-14 05:00:03 +00003334- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3335 since mimetools itself is deprecated. Because modules are cached, all
3336 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3337
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003338- Issue #3134: shutil referenced undefined WindowsError symbol.
3339
Robert Schuppenies14646332008-08-10 11:01:53 +00003340- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3341 menu entries were not deleted.
3342
Brett Cannon83e81842008-08-09 23:30:55 +00003343- Copied the implementation of reduce() to _functools.reduce() to have a
3344 version that did not raise a DeprecationWarning under -3.
3345
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003346- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3347 a MemoryError rather than silently stop the iteration.
3348
Guido van Rossum59ce9012008-08-09 14:55:34 +00003349- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3350 to _sre.compile() will now be rejected. This should not affect anybody
3351 since the re.compile() function never generates invalid re-bytecode.
3352
Skip Montanaroa032bf42008-08-08 22:52:51 +00003353- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3354 upon first access it can be automatically initialized from the csv file if
3355 it wasn't initialized during instantiation.
3356
Brett Cannon3aa2a492008-08-06 22:28:09 +00003357- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3358 the reload() built-in has been removed.
3359
Brett Cannon7e30b672008-08-04 21:52:25 +00003360- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003361 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003372 asking for a specific length. This problem only affected files opened
3373 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003374

3429-----------------
3430
Georg Brandl3e483f62008-07-16 22:57:41 +00003431- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3432 its methods now allow for items objects that can be converted to
3433 an integer using operator.index().
3434
Mark Dickinson64b7e502008-07-16 09:40:03 +00003435- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3436 produced a ValueError instead of giving the correct float.
3437
Eric Smitha5fa5a22008-07-16 00:11:49 +00003438- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3439 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3440
Mark Dickinson7103aa42008-07-15 19:08:33 +00003441- Issue #3008: the float type has a new instance method 'float.hex'
3442 and a new class method 'float.fromhex' to convert floating-point
3443 numbers to and from hexadecimal strings, respectively.
3444
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003445- Issue #2235: __hash__ is once again inherited by default. To allow
3446 collections.Hashable to remain meaningful in the presence of the
3447 default hash implementation (object.__hash__), it is now possible
3448 to explicit block inheritance of hash by setting __hash__=None at
3449 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3450 level.
3451
Nick Coghlanb028f502008-07-13 14:52:36 +00003452- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3453 the parent module cannot be found while performing an absolute import.
3454 This means that an incorrectly defined __package__ attribute will
3455 now only prevent relative imports in that module rather than causing
3456 all imports from that module to fail.
3457
Nick Coghlan14ff9942008-07-08 14:21:42 +00003458- Issue #2517: Allow unicode messages in Exceptions again by correctly

3463 set to a custom object whose write() method happens to install
3464 another file in sys.stdout.

3467 threading.local: the first member set by a thread could be saved in
3468 another thread's dictionary.
3469
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003470- Issue #3004: Minor change to slice.indices(): the start and stop
3471 arguments are now treated identically, making the behaviour easier
3472 to describe and understand. For example, slice(None, -10,
3473 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3474 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3475 10, -1).
3476
Georg Brandl278fc502008-07-19 12:46:12 +00003477- Issue #3219: Calling a function with repeated keyword arguments,
3478 f(a=2, a=23), would not cause a syntax error. This was a regression
3479 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003480
Georg Brandl278fc502008-07-19 12:46:12 +00003481- Issue #2862: Make int and float freelist management consistent with
3482 other freelists. Changes their CompactFreeList apis into
3483 ClearFreeList apis and calls them via gc.collect().

3489 api functions without holding the GIL, which could lead to a fatal
3490 error when they failed.
3491
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003492- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003517- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3518 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003519 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003520 content-length. The problem had been corrected in the 2.4 branch, but never
3521 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003536- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3537 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003991- Issue #1631171: Re-implement the 'warnings' module in C (the
3992 original Python code has been kept as backup). This will allow for
3993 using the 'warning's machinery in such places as the parser where
3994 use of pure Python code is not possible. Both the ``showarning()``
3995 and ``formatwarning()`` gain an optional 'line' argument which is
3996 not called by default for backwards-compatibility reasons. Setting
3997 ``warnings.showwarning()`` to an implementation that lacks support
3998 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004061- Issue #2550: The approach used by client/server code for obtaining
4062 ports to listen on in network-oriented tests has been refined in an
4063 effort to facilitate running multiple instances of the entire
4064 regression test suite in parallel without issue.
4065 test_support.bind_port() has been fixed such that it will always
4066 return a unique port -- which wasn't always the case with the
4067 previous implementation, especially if socket options had been set
4068 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4069 new implementation of bind_port() will actually raise an exception
4070 if it is passed an AF_INET/SOCK_STREAM socket with either the
4071 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4072 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4073 the socket it's been passed. This currently only applies to
4074 Windows. This option prevents any other sockets from binding to the
4075 host/port we've bound to, thus removing the possibility of the
4076 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4077 when a second SOCK_STREAM socket binds and accepts to a host/port
4078 that's already been bound by another socket. The optional preferred
4079 port parameter to bind_port() has been removed. Under no
4080 circumstances should tests be hard coding ports!
4081
4082 test_support.find_unused_port() has also been introduced, which will
4083 pass a temporary socket object to bind_port() in order to obtain an
4084 unused port. The temporary socket object is then closed and
4085 deleted, and the port is returned. This method should only be used
4086 for obtaining an unused port in order to pass to an external program
4087 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4088 a parameter to a server-oriented class that doesn't give you direct
4089 access to the underlying socket used.
4090
4091 Finally, test_support.HOST has been introduced, which should be used
4092 for the host argument of any relevant socket calls (i.e. bind and
4093 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004094
4095 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004096 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004097 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4098 test_asynchat and test_socket_ssl.
4099
Georg Brandl3ee81df2008-05-17 18:14:43 +00004100 It is now possible for multiple instances of the regression test
4101 suite to run in parallel without issue.

4368-----------------
4369
Fred Drakea8ee94b2008-03-01 02:45:07 +00004370- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004371 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00004377- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004378 issue 215555 for a discussion.
4379
Eric Smitha73fbe72008-02-23 03:09:44 +00004380- Added the future_builtins module, which contains hex() and oct().
4381 These are the PEP 3127 version of these functions, designed to be
4382 compatible with the hex() and oct() builtins from Python 3.0. They
4383 differ slightly in their output formats from the existing, unchanged
4384 Python 2.6 builtins. The expected usage of the future_builtins
4385 module is:
4386 from future_builtins import hex, oct
4387
Eric Smith7ef40bf2008-02-20 23:34:22 +00004388- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4389 exponents for exponents with absolute value < 100. Follows C99
4390 standard. This is a change on Windows, which would use 3 digits.
4391 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4392 so that any alterations it does to the resulting string will be
4393 available in stringlib/formatter.h (for float.__format__).
4394
Eric Smith5a3c1352008-02-19 13:21:56 +00004395- Implemented PEP 3101, Advanced String Formatting. This adds a new
4396 builtin format(); a format() method for str and unicode; a
4397 __format__() method to object, str, unicode, int, long, float, and
4398 datetime; the class string.Formatter; and the C API
4399 PyObject_Format().
4400
Georg Brandl3ee81df2008-05-17 18:14:43 +00004401- Fixed several potential crashes, all caused by specially crafted
4402 __del__ methods exploiting objects in temporarily inconsistent
4403 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004404
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004405- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004406 prevent a possible crash: an Abstract Base Class would try to access
4407 a slot on a registered virtual subclass.

4414 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004415
Georg Brandl3ee81df2008-05-17 18:14:43 +00004416- Issue #2045: Fix an infinite recursion triggered when printing a
4417 subclass of collections.defaultdict, if its default_factory is set
4418 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004419
Christian Heimesf75dbef2008-02-08 00:11:31 +00004420- Fixed a minor memory leak in dictobject.c. The content of the free
4421 list was not freed on interpreter shutdown.
4422
Georg Brandl21e99f42010-03-07 15:23:59 +00004423- Limit free list of method and built-in function objects to 256

4427 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004428 to compact the internal free lists of pre-allocted ints and floats.
4429
Georg Brandl3ee81df2008-05-17 18:14:43 +00004430- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4431 calls. Python expected the return type int but the fork familie
4432 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004446- Patch #1473257: generator objects gain a gi_code attribute. This is
4447 the same object as the func_code attribute of the function that
4448 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004449
Georg Brandl3ee81df2008-05-17 18:14:43 +00004450- Issue #1920: "while 0" statements were completely removed by the
4451 compiler, even in the presence of an "else" clause, which is
4452 supposed to be run when the condition is false. Now the compiler
4453 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004454

4462
Georg Brandl3ee81df2008-05-17 18:14:43 +00004463- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004464 several extension methods and modules do not work without unicode

Georg Brandl6caad7d2008-01-26 14:19:22 +00004472- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004473 added.
4474
Christian Heimesc94e2b52008-01-14 04:13:37 +00004475- sys.float_info / PyFloat_GetInfo: The floating point information
4476 object was converted from a dict to a specialized structseq object.
4477
Georg Brandl3ee81df2008-05-17 18:14:43 +00004478- Patch #1816: Added sys.flags structseq. It exposes the status of
4479 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004480
Georg Brandl3ee81df2008-05-17 18:14:43 +00004481- Objects/structseq.c: Implemented new structseq representation. The
4482 patch makes structseqs (e.g. the return value of os.stat) more
4483 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004484
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- Patch #1700288: added a type attribute cache that caches method
4486 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004487
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004488- Bug #1776: __import__() no longer accepts filenames on any platform.
4489 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004490
Georg Brandlaed6c662008-01-07 17:25:53 +00004491- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4492
Georg Brandl3ee81df2008-05-17 18:14:43 +00004493- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4494 envvar and sys.dont_write_bytecode attribute. All these can be set
4495 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004496
Georg Brandl3ee81df2008-05-17 18:14:43 +00004497- Improve some exception messages when Windows fails to load an
4498 extension module. Now we get for example '%1 is not a valid Win32
4499 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004500

Georg Brandl3ee81df2008-05-17 18:14:43 +00004503- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4504 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004505
Christian Heimes0a8143f2007-12-18 23:22:54 +00004506- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004507 and INF. float("nan"), float("inf") and float("-inf") now work on
4508 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004509
Georg Brandl3ee81df2008-05-17 18:14:43 +00004510- Compiler now generates simpler and faster code for dictionary
4511 literals. The oparg for BUILD_MAP now indicates an estimated
4512 dictionary size. There is a new opcode, STORE_MAP, for adding
4513 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004542- Patch #1739468: Directories and zipfiles containing a __main__.py
4543 file can now be directly executed by passing their name to the
4544 interpreter. The directory/zipfile is automatically inserted as the
4545 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004546
Georg Brandl3ee81df2008-05-17 18:14:43 +00004547- Issue #1265: Fix a problem with sys.settrace, if the tracing
4548 function uses a generator expression when at the same time the
4549 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004550
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004551- sets and frozensets now have an isdisjoint() method.
4552
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004553- optimize the performance of builtin.sum().
4554
Neal Norwitz44f326e2007-10-05 05:29:17 +00004555- Fix warnings found by the new version of the Coverity checker.
4556
Georg Brandl21e99f42010-03-07 15:23:59 +00004557- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004558 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4559 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004560
Georg Brandl3ee81df2008-05-17 18:14:43 +00004561- Issue #1686386: Tuple's tp_repr did not take into account the
4562 possibility of having a self-referential tuple, which is possible
4563 from C code. Nor did object's tp_str consider that a type's tp_str
4564 could do something that could lead to an inifinite recursion.
4565 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4566 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004567
Georg Brandl3ee81df2008-05-17 18:14:43 +00004568- Issue #1164: It was possible to trigger deadlock when using the
4569 'print' statement to write to a file since the GIL was not released
4570 as needed. Now PyObject_Print() does the right thing along with
4571 various tp_print implementations of the built-in types and those in
4572 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004573
Georg Brandl3ee81df2008-05-17 18:14:43 +00004574- Issue #1147: Exceptions were directly allowing string exceptions in
4575 their throw() method even though string exceptions no longer
4576 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004577
Georg Brandl3ee81df2008-05-17 18:14:43 +00004578- Issue #1096: Prevent a segfault from getting the repr of a very
4579 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004580
Brett Cannon1e534b52007-09-07 04:18:30 +00004581- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004582 PyObject_Call() never calling back out to Python code to trigger
4583 recursion depth updates/checks. Required the creation of a static
4584 RuntimeError instance in case normalizing an exception put the
4585 recursion check value past its limit. Fixes crashers
4586 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004587

Neal Norwitz0ac60192007-05-27 04:08:54 +00004601- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004602 __*__ attributes. (Some already existed, e.g., __doc__ and
4603 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004604
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004605- Add -3 option to the interpreter to warn about features that are
4606 deprecated and will be changed/removed in Python 3.0.
4607
Georg Brandl2134e752007-05-21 20:34:16 +00004608- Patch #1686487: you can now pass any mapping after '**' in function
4609 calls.
4610
Collin Winter62903052007-05-18 23:11:24 +00004611- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004612 "except E as target:". This is to provide forwards compatibility
4613 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004614
Brett Cannon229cee22007-05-05 01:34:02 +00004615- Deprecate BaseException.message as per PEP 352.
4616
Georg Brandl3ee81df2008-05-17 18:14:43 +00004617- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004618 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004619
Vinay Sajip8549ce32007-05-06 17:53:37 +00004620- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004621 setting a plain string, ie don't expand to single letter identifiers.
4622
Raymond Hettinger13936692007-04-11 18:40:58 +00004623- Request #1191699: Slices can now be pickled.
4624
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004625- Request #1193128: str.translate() now allows a None argument for
4626 translations that only remove characters without re-mapping the
4627 remaining characters.
4628
Georg Brandl5cb76c12007-03-21 09:00:39 +00004629- Patch #1682205: a TypeError while unpacking an iterable is no longer
4630 masked by a generic one with the message "unpack non-sequence".
4631
Neal Norwitzaa754b72007-03-21 06:39:48 +00004632- Remove unused file Python/fmod.c.
4633
Guido van Rossum143b5642007-03-23 04:58:42 +00004634- Bug #1683368: The object.__init__() and object.__new__() methods are
4635 now stricter in rejecting excess arguments. The only time when
4636 either allows excess arguments is when it is not overridden and the
4637 other one is. For backwards compatibility, when both are
4638 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004639 warning later). Also, type.__init__() insists on the same signature
4640 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004641
Georg Brandl3ee81df2008-05-17 18:14:43 +00004642- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4643 object to complex using its __complex__() method before falling back
4644 to the __float__() method. Therefore, the functions in the cmath
4645 module now can operate on objects that define a __complex__()
4646 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004647
Georg Brandl3ee81df2008-05-17 18:14:43 +00004648- Patch #1623563: allow __class__ assignment for classes with
4649 __slots__. The old and the new class are still required to have the
4650 same slot names.

4656 ``object.__reduce_ex__()`` is called with an object that is faking
4657 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004658
Georg Brandl3ee81df2008-05-17 18:14:43 +00004659- Patch #1680015: Don't modify __slots__ tuple if it contains an

4663
Georg Brandl7b9c5552007-03-12 14:30:05 +00004664- Bug #1678647: write a newline after printing an exception in any
4665 case, even when converting the value to a string failed.
4666
Georg Brandl871f1bc2007-03-12 13:17:36 +00004667- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004668 its argument, if it exists. If not, it will work like before. This
4669 allows customizing the output of dir() in the presence of a
4670 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004672- Patch #922167: Python no longer segfaults when faced with infinitely
4673 self-recursive reload() calls (as reported by bug #742342).
4674
Georg Brandl3ee81df2008-05-17 18:14:43 +00004675- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004678- Patch #1491866: change the complex() constructor to allow
4679 parthensized forms. This means complex(repr(x)) now works instead of
4680 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004681
Georg Brandlaa2321b2007-03-07 00:40:28 +00004682- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004683 makes the filenames the warning module prints much more sensible
4684 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004685
Georg Brandl49aafc92007-03-07 00:34:46 +00004686- Variant of patch #697613: don't exit the interpreter on a SystemExit
4687 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004688 variable is given, but break into the interactive interpreter just
4689 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004697- Patch #1674228: when assigning a slice (old-style), check for the
4698 sq_ass_slice instead of the sq_slice slot.
4699
Georg Brandl3ee81df2008-05-17 18:14:43 +00004700- When printing an unraisable error, don't print exceptions. before
4701 the name. This duplicates the behavior whening normally printing
4702 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004703

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005204- Added a timeout parameter to the constructor of other protocols
5205 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5206 work started with create_connection() and timeout in httplib, and
5207 closes patch #723312.
5208
Vinay Sajip8549ce32007-05-06 17:53:37 +00005209- Patch #1676823: Added create_connection() to socket.py, which may be

5233
Georg Brandlf66b6032007-03-14 08:27:52 +00005234- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005235 AttributeError instead of an IOError when the server's response
5236 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005237
Georg Brandl3ee81df2008-05-17 18:14:43 +00005238- Patch #957650: "%var%" environment variable references are now

Georg Brandl3ee81df2008-05-17 18:14:43 +00005242- Patch #1429539: pdb now correctly initializes the __main__ module
5243 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005244 correctly now.
5245

5252
Georg Brandl3ee81df2008-05-17 18:14:43 +00005253- Patch #1530482: add pydoc.render_doc() which returns the

5263 parameter which can be set to False to prevent the default
5264 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00005265
Georg Brandl9e6b4702007-03-13 18:15:41 +00005266- Patch #1581073: add a flag to textwrap that prevents the dropping of
5267 whitespace while wrapping.
5268
Georg Brandl92a6bae2007-03-13 17:43:32 +00005269- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005270 are set for invalid interpolation sequences that would lead to
5271 errors on reading back those values.

5314 returned string up to the first NUL character.

5325
Georg Brandl3ee81df2008-05-17 18:14:43 +00005326- unittest now verifies more of its assumptions. In particular,
5327 TestCase and TestSuite subclasses (not instances) are no longer
5328 accepted in TestSuite.addTest(). This should cause no
5329 incompatibility since it never made sense with ordinary subclasses
5330 -- the failure just occurred later, with a more cumbersome
5331 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00005332

5341
Georg Brandl3ee81df2008-05-17 18:14:43 +00005342- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00005720 time so that opening a database previously created with the DB_DUP
5721 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5722 opens. Specifically: dictionary assignment to a DB object will
5723 replace all values for a given key when the database allows
5724 duplicate values. DB users should use DB.put(k, v) when they want
5725 to store duplicates; not DB[k] = v.

5732 characters with ASCII value less than 32. Also, it correctly quotes
5733 dots only if they occur on a single line, as opposed to the previous
5734 behavior of quoting dots if they are the second character of any
5735 line.
