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

1204-----------------
1205
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001206- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1207 start byte and the continuation byte(s) are now considered invalid, instead
1208 of the number of bytes specified by the start byte.
1209 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1210 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1211 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1212 Previous versions returned a single u'\ufffd'.
1213
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001214- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001215 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1216 arises from the "Overriding __eq__ blocks inheritance ..." warning
1217 when turned into an exception: in this case the exception simply
1218 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001219
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001220- Issue #8748: Fix two issues with comparisons between complex and integer
1221 objects. (1) The comparison could incorrectly return True in some cases
1222 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1223 (2) The comparison raised an OverflowError for large integers, leading
1224 to unpredictable exceptions when combining integers and complex objects
1225 in sets or dicts.
1226
Mark Dickinson81336372010-05-30 12:12:25 +00001227- Issue #5211: Implicit coercion for the complex type is now completely
1228 removed. (Coercion for arithmetic operations was already removed in 2.7
1229 alpha 4, but coercion for rich comparisons was accidentally left in.)
1230
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001231- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
1232 and error handler, instead of writing to the C stderr file in utf-8
1233
Georg Brandlfee0f442010-05-22 21:26:21 +00001234- Issue #7902: When using explicit relative import syntax, don't try implicit
1235 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00001236
Georg Brandlfee0f442010-05-22 21:26:21 +00001237- Issue #7079: Fix a possible crash when closing a file object while using it
1238 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +00001239
Victor Stinnerb65bd2e2010-06-11 19:22:28 +00001240- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00001241 Window Server again in a framework build on MacOSX 10.5 or earlier.

1245
Georg Brandlfee0f442010-05-22 21:26:21 +00001246- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
1247 of the interpreter to set sys.argv without also modifying sys.path. This
1248 helps fix `CVE-2008-5983

1273
R. David Murray52dcd452010-06-02 22:03:15 +00001274- Issue #1368247: set_charset (and therefore MIMEText) now automatically

1365 non-float non-integer argument is now converted to an integer (if possible)
1366 using its __int__ method. Previously, only small arguments were treated this
1367 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00001607- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1608 with a non-empty format string. This is an effort to future-proof user
1609 code. If a derived class does not currently implement __format__ but later
1610 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001611 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001612 Python 3.3 and it will be an error in Python 3.4.

1663 InvalidOperation instead of returning False. (Comparisons involving a quiet
1664 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1665 signaling NaNs remain unhashable.

2029 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002030 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00002044- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2045 and add the additional members returned in an OSVERSIONINFOEX structure. The
2046 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002049- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2050 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2051 returning NULL. The macro now returns a statically allocated empty string
2052 instead.

2062 strings,
2063 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2064 numeric strings corresponding to subnormal values,
2065 (3) a memory leak for some values large enough to cause overflow, and
2066 (4) a number of flaws that could lead to incorrectly rounded results.

2085
Georg Brandlba83f822010-03-14 09:50:54 +00002086- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

Antoine Pitroud840e512010-02-04 20:20:18 +00002097- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002098 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002099 Also, raise ValueError rather than TypeError when an unknown TIPC address
2100 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002104- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002105 file position when calling `truncate()`. It would previously change the file
2106 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002107 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2108
Georg Brandlba83f822010-03-14 09:50:54 +00002109- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2110 class used to represent files stored inside an archive. The new
2111 implementation is significantly faster and can be wrapped in a
2112 ``io.BufferedReader`` object for more speedups. It also solves an issue
2113 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2114 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002124- Issue #7748: Since unicode values are supported for some metadata options in
2125 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2126 encoded string for them. This ensures that the upload and register commands
2127 send the correct values to PyPI without any error.

2209
Mark Dickinson1b34d252010-01-01 17:27:30 +00002210- Issue #5080: A number of functions and methods previously produced a

2212 These functions and methods now raise TypeError instead. The majority of the
2213 effects of this change are in the extension modules, but some core functions
2214 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2215 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002398- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2399 decimal string that's guaranteed to round back to x under correct rounding
2400 (with round-half-to-even rounding mode). Previously it gave a string based on
2401 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2402 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2403 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002405- Issue #7117: On almost all platforms: float-to-string and string-to-float
2406 conversions within Python are now correctly rounded. Places these conversions
2407 occur include: str for floats and complex numbers; the float and complex
2408 constructors; old-style and new-style numeric formatting; serialization and
2409 deserialization of floats and complex numbers using marshal, pickle and json;
2410 parsing of float and imaginary literals in Python code; Decimal-to-float
2411 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002412
Georg Brandlba83f822010-03-14 09:50:54 +00002413 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2414 providing correctly-rounded strtod and dtoa C functions. This code is
2415 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2416 the C compiler. There may be a small number of platforms on which correct
2417 operation of this code cannot be guaranteed, so the code is not used: notably,
2418 this applies to platforms where the C double format is not IEEE 754 binary64,
2419 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2420 and Python's configure script is unable to determine how to change the FPU
2421 precision. On these platforms conversions use the platform strtod and dtoa,
2422 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002424- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2425 uses the correctly-rounded string <-> float conversions described above (when
2426 available), and so produces correctly rounded results that will display nicely
2427 under the float repr. There are two related small changes: (1) round now
2428 accepts any class with an ``__index__()`` method for its second argument (but
2429 no longer accepts floats for the second argument), and (2) an excessively
2430 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2431 raises an exception.

4014 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4015 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004214- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

4216 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4217 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00004315 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4316 for catch_warnings() also led to an improvement in the raising of a
4317 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004383What's New in Python 2.6 beta 3?
4384================================
4385
Barry Warsaw07a4a382008-08-21 01:15:08 +00004386*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004387
4388Core and Builtins
4389-----------------
4390
Guido van Rossumf8402962008-08-20 15:01:50 +00004391- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4392 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4393 extensions do not automatically benefit from the class attribute
4394 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4395 to their tp_flags field if they care. This is a backwards
4396 compatibility feature; in 3.0, all types will use the cache by
4397 default.
4398
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004399- Keyword arguments can now follow starred arguments. (``f(a, *args,
4400 keyword=23)`` is now valid syntax.)
4401
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004402- ctypes function pointers that are COM methods have a boolean True
4403 value again.
4404
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004405- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4406 by denying s# to parse objects that have a releasebuffer procedure,
4407 and introducing s*.
4408
Georg Brandl1e13ea92008-08-11 09:07:59 +00004409- Issue #3537: Fix an assertion failure when an empty but presized dict
4410 object was stored in the freelist.
4411
Mark Dickinsonb6467572008-08-04 21:30:09 +00004412- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4413 ValueError consistently across platforms.
4414
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004415- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4416 (64bit Unix, for example), unichr() would truncate its argument and return
4417 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4418
Neal Norwitze7d8be82008-07-31 17:17:14 +00004419- Apply security patches from Apple.
4420
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004421- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4422 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4423
Antoine Pitrou92f82162008-07-25 22:22:08 +00004424- Issue #1819: function calls with several named parameters are now on
4425 average 35% faster (as measured by pybench).
4426
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004427- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4428 the python debugger steps into a class statement: the free variables (local
4429 variables defined in an outer scope) would be deleted from the outer scope.
4430
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004431- Issue #2620: Overflow checking when allocating or reallocating memory
4432 was not always being done properly in some python types and extension
4433 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4434 all been updated to perform better checks and places in the code that
4435 would previously leak memory on the error path when such an allocation
4436 failed have been fixed.

4439-------
4440
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004441- Issue #3612: Added some missing basic types in ctypes.wintypes.
4442
Benjamin Petersone977ad42008-08-20 01:42:01 +00004443- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4444 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4445
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004446- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4447 version reported by these tools does not necessarily follow the python
4448 version numbering scheme, so the module is less strict when parsing it.
4449
Nick Coghlanf70385a2008-08-18 12:42:46 +00004450- Issue #2235: Added Py3k warnings for types which will become unhashable
4451 under the stricter __hash__ inheritance rules in 3.0. Several types
4452 which did not meet the rules for hash invariants and were already
4453 unhashable in 3.0 have now been explicitly flagged as unhashable in
4454 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4455 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4456
Brett Cannon88f801d2008-08-18 00:46:22 +00004457- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4458 imported into the module but exposed as part of the module's API.
4459
Brett Cannon7b96f072008-08-18 00:41:11 +00004460- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4461
Brett Cannon46225e72008-08-18 00:36:52 +00004462- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004464- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4465
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004466- Issue #3575: Incremental decoder's decode function now takes bytearray
4467 by using 's*' instead of 't#'.
4468
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004469- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004470 fails unicode conversion on 2nd parameter. (windows only)
4471
Georg Brandl222e2082010-08-01 22:27:39 +00004472- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004473 in a redirect.
4474
Brett Cannonabe423e2008-08-16 21:47:07 +00004475- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004476 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004477
Facundo Batistaeb90b782008-08-16 14:44:07 +00004478- Issue #2776: fixed small issue when handling an URL with double slash
4479 after a 302 response in the case of not going through a proxy.
4480
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004481- Issue #2676: in the email package, content-type parsing was hanging on
4482 pathological input because of quadratic or exponential behaviour of a
4483 regular expression.
4484
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004485- Issue #3476: binary buffered reading through the new "io" library is now
4486 thread-safe.
4487
Brett Cannonbf3157b2008-08-14 05:00:03 +00004488- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4489 since mimetools itself is deprecated. Because modules are cached, all
4490 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4491
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004492- Issue #3134: shutil referenced undefined WindowsError symbol.
4493
Robert Schuppenies14646332008-08-10 11:01:53 +00004494- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4495 menu entries were not deleted.
4496
Brett Cannon83e81842008-08-09 23:30:55 +00004497- Copied the implementation of reduce() to _functools.reduce() to have a
4498 version that did not raise a DeprecationWarning under -3.
4499
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004500- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4501 a MemoryError rather than silently stop the iteration.
4502
Guido van Rossum59ce9012008-08-09 14:55:34 +00004503- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4504 to _sre.compile() will now be rejected. This should not affect anybody
4505 since the re.compile() function never generates invalid re-bytecode.
4506
Skip Montanaroa032bf42008-08-08 22:52:51 +00004507- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4508 upon first access it can be automatically initialized from the csv file if
4509 it wasn't initialized during instantiation.
4510
Brett Cannon3aa2a492008-08-06 22:28:09 +00004511- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4512 the reload() built-in has been removed.
4513
Brett Cannon7e30b672008-08-04 21:52:25 +00004514- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004515 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4518 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4519 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4520 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Antoine Pitroude781a42008-08-09 12:43:23 +00004526 asking for a specific length. This problem only affected files opened
4527 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004528
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004529- Issue #3449: Update decimal module to use most recent specification
4530 (v. 1.68) and tests (v. 2.58) from IBM.

4583-----------------
4584
Georg Brandl3e483f62008-07-16 22:57:41 +00004585- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4586 its methods now allow for items objects that can be converted to
4587 an integer using operator.index().
4588
Mark Dickinson64b7e502008-07-16 09:40:03 +00004589- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4590 produced a ValueError instead of giving the correct float.
4591
Eric Smitha5fa5a22008-07-16 00:11:49 +00004592- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4593 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4594
Mark Dickinson7103aa42008-07-15 19:08:33 +00004595- Issue #3008: the float type has a new instance method 'float.hex'
4596 and a new class method 'float.fromhex' to convert floating-point
4597 numbers to and from hexadecimal strings, respectively.
4598
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004599- Issue #2235: __hash__ is once again inherited by default. To allow
4600 collections.Hashable to remain meaningful in the presence of the
4601 default hash implementation (object.__hash__), it is now possible
4602 to explicit block inheritance of hash by setting __hash__=None at
4603 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4604 level.
4605
Nick Coghlanb028f502008-07-13 14:52:36 +00004606- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4607 the parent module cannot be found while performing an absolute import.
4608 This means that an incorrectly defined __package__ attribute will
4609 now only prevent relative imports in that module rather than causing
4610 all imports from that module to fail.
4611
Nick Coghlan14ff9942008-07-08 14:21:42 +00004612- Issue #2517: Allow unicode messages in Exceptions again by correctly

4621 threading.local: the first member set by a thread could be saved in
4622 another thread's dictionary.
4623
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004624- Issue #3004: Minor change to slice.indices(): the start and stop
4625 arguments are now treated identically, making the behaviour easier
4626 to describe and understand. For example, slice(None, -10,
4627 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4628 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4629 10, -1).
4630
Georg Brandl278fc502008-07-19 12:46:12 +00004631- Issue #3219: Calling a function with repeated keyword arguments,
4632 f(a=2, a=23), would not cause a syntax error. This was a regression
4633 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004634
Georg Brandl278fc502008-07-19 12:46:12 +00004635- Issue #2862: Make int and float freelist management consistent with
4636 other freelists. Changes their CompactFreeList apis into

4643 api functions without holding the GIL, which could lead to a fatal
4644 error when they failed.
4645
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004646- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004671- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4672 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004673 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004674 content-length. The problem had been corrected in the 2.4 branch, but never
4675 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004690- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4691 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00005145- Issue #1631171: Re-implement the 'warnings' module in C (the
5146 original Python code has been kept as backup). This will allow for
5147 using the 'warning's machinery in such places as the parser where
5148 use of pure Python code is not possible. Both the ``showarning()``
5149 and ``formatwarning()`` gain an optional 'line' argument which is
5150 not called by default for backwards-compatibility reasons. Setting
5151 ``warnings.showwarning()`` to an implementation that lacks support
5152 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005215- Issue #2550: The approach used by client/server code for obtaining
5216 ports to listen on in network-oriented tests has been refined in an
5217 effort to facilitate running multiple instances of the entire
5218 regression test suite in parallel without issue.
5219 test_support.bind_port() has been fixed such that it will always
5220 return a unique port -- which wasn't always the case with the
5221 previous implementation, especially if socket options had been set
5222 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5223 new implementation of bind_port() will actually raise an exception
5224 if it is passed an AF_INET/SOCK_STREAM socket with either the
5225 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5226 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5227 the socket it's been passed. This currently only applies to
5228 Windows. This option prevents any other sockets from binding to the
5229 host/port we've bound to, thus removing the possibility of the
5230 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5231 when a second SOCK_STREAM socket binds and accepts to a host/port
5232 that's already been bound by another socket. The optional preferred
5233 port parameter to bind_port() has been removed. Under no
5234 circumstances should tests be hard coding ports!
5235
5236 test_support.find_unused_port() has also been introduced, which will
5237 pass a temporary socket object to bind_port() in order to obtain an
5238 unused port. The temporary socket object is then closed and
5239 deleted, and the port is returned. This method should only be used
5240 for obtaining an unused port in order to pass to an external program
5241 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5242 a parameter to a server-oriented class that doesn't give you direct
5243 access to the underlying socket used.
5244
5245 Finally, test_support.HOST has been introduced, which should be used
5246 for the host argument of any relevant socket calls (i.e. bind and
5247 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005248
5249 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005250 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005251 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5252 test_asynchat and test_socket_ssl.
5253
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254 It is now possible for multiple instances of the regression test
5255 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005534- Added the future_builtins module, which contains hex() and oct().
5535 These are the PEP 3127 version of these functions, designed to be
5536 compatible with the hex() and oct() builtins from Python 3.0. They
5537 differ slightly in their output formats from the existing, unchanged
5538 Python 2.6 builtins. The expected usage of the future_builtins
5539 module is:
5540 from future_builtins import hex, oct
5541
Eric Smith7ef40bf2008-02-20 23:34:22 +00005542- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5543 exponents for exponents with absolute value < 100. Follows C99
5544 standard. This is a change on Windows, which would use 3 digits.
5545 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5546 so that any alterations it does to the resulting string will be
5547 available in stringlib/formatter.h (for float.__format__).
5548
Eric Smith5a3c1352008-02-19 13:21:56 +00005549- Implemented PEP 3101, Advanced String Formatting. This adds a new
5550 builtin format(); a format() method for str and unicode; a
5551 __format__() method to object, str, unicode, int, long, float, and
5552 datetime; the class string.Formatter; and the C API
5553 PyObject_Format().
5554
Georg Brandl3ee81df2008-05-17 18:14:43 +00005555- Fixed several potential crashes, all caused by specially crafted
5556 __del__ methods exploiting objects in temporarily inconsistent
5557 state.

5568 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005569
Georg Brandl3ee81df2008-05-17 18:14:43 +00005570- Issue #2045: Fix an infinite recursion triggered when printing a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005600- Patch #1473257: generator objects gain a gi_code attribute. This is
5601 the same object as the func_code attribute of the function that
5602 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005603
Georg Brandl3ee81df2008-05-17 18:14:43 +00005604- Issue #1920: "while 0" statements were completely removed by the
5605 compiler, even in the presence of an "else" clause, which is
5606 supposed to be run when the condition is false. Now the compiler
5607 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005608

Christian Heimes082c9b02008-01-23 14:20:50 +00005618 several extension methods and modules do not work without unicode
5619 support.
5620
Georg Brandl26543b12008-01-21 18:36:51 +00005621- Issue #1882: when compiling code from a string, encoding cookies in the
5622 second line of code were not always recognized correctly.
5623
Georg Brandl14404b62008-01-19 19:27:05 +00005624- Issue #1679: "0x" was taken as a valid integer literal.
5625
Georg Brandl6caad7d2008-01-26 14:19:22 +00005626- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005627 added.
5628
Christian Heimesc94e2b52008-01-14 04:13:37 +00005629- sys.float_info / PyFloat_GetInfo: The floating point information
5630 object was converted from a dict to a specialized structseq object.
5631
Georg Brandl3ee81df2008-05-17 18:14:43 +00005632- Patch #1816: Added sys.flags structseq. It exposes the status of
5633 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005634
Georg Brandl3ee81df2008-05-17 18:14:43 +00005635- Objects/structseq.c: Implemented new structseq representation. The
5636 patch makes structseqs (e.g. the return value of os.stat) more
5637 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005638
Georg Brandl3ee81df2008-05-17 18:14:43 +00005639- Patch #1700288: added a type attribute cache that caches method
5640 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005641
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005642- Bug #1776: __import__() no longer accepts filenames on any platform.
5643 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005644
Georg Brandlaed6c662008-01-07 17:25:53 +00005645- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5646
Georg Brandl3ee81df2008-05-17 18:14:43 +00005647- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5648 envvar and sys.dont_write_bytecode attribute. All these can be set
5649 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005650
Georg Brandl3ee81df2008-05-17 18:14:43 +00005651- Improve some exception messages when Windows fails to load an
5652 extension module. Now we get for example '%1 is not a valid Win32
5653 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005654
Georg Brandl3ee81df2008-05-17 18:14:43 +00005655- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005657- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5658 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005659
Christian Heimes0a8143f2007-12-18 23:22:54 +00005660- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005661 and INF. float("nan"), float("inf") and float("-inf") now work on
5662 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005663
Georg Brandl3ee81df2008-05-17 18:14:43 +00005664- Compiler now generates simpler and faster code for dictionary
5665 literals. The oparg for BUILD_MAP now indicates an estimated
5666 dictionary size. There is a new opcode, STORE_MAP, for adding
5667 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005677- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005678 SystemError.
5679
Nick Coghlanef01d822007-12-03 12:55:17 +00005680- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005696- Patch #1739468: Directories and zipfiles containing a __main__.py
5697 file can now be directly executed by passing their name to the
5698 interpreter. The directory/zipfile is automatically inserted as the
5699 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005700
Georg Brandl3ee81df2008-05-17 18:14:43 +00005701- Issue #1265: Fix a problem with sys.settrace, if the tracing
5702 function uses a generator expression when at the same time the
5703 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005704
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005705- sets and frozensets now have an isdisjoint() method.
5706
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005707- optimize the performance of builtin.sum().
5708
Neal Norwitz44f326e2007-10-05 05:29:17 +00005709- Fix warnings found by the new version of the Coverity checker.
5710
Georg Brandl21e99f42010-03-07 15:23:59 +00005711- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005712 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5713 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005714
Georg Brandl3ee81df2008-05-17 18:14:43 +00005715- Issue #1686386: Tuple's tp_repr did not take into account the
5716 possibility of having a self-referential tuple, which is possible
5717 from C code. Nor did object's tp_str consider that a type's tp_str
5718 could do something that could lead to an inifinite recursion.
5719 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5720 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005721
Georg Brandl3ee81df2008-05-17 18:14:43 +00005722- Issue #1164: It was possible to trigger deadlock when using the
5723 'print' statement to write to a file since the GIL was not released
5724 as needed. Now PyObject_Print() does the right thing along with
5725 various tp_print implementations of the built-in types and those in
5726 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005727
Georg Brandl3ee81df2008-05-17 18:14:43 +00005728- Issue #1147: Exceptions were directly allowing string exceptions in
5729 their throw() method even though string exceptions no longer
5730 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005731
Georg Brandl3ee81df2008-05-17 18:14:43 +00005732- Issue #1096: Prevent a segfault from getting the repr of a very
5733 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005734
Brett Cannon1e534b52007-09-07 04:18:30 +00005735- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005736 PyObject_Call() never calling back out to Python code to trigger
5737 recursion depth updates/checks. Required the creation of a static
5738 RuntimeError instance in case normalizing an exception put the
5739 recursion check value past its limit. Fixes crashers
5740 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005741
Georg Brandl3ee81df2008-05-17 18:14:43 +00005742- Patch #1031213: Decode source line in SyntaxErrors back to its

5746 with %G.
5747
Georg Brandl3ee81df2008-05-17 18:14:43 +00005748- Prevent expandtabs() on string and unicode objects from causing a
5749 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005755- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005756 __*__ attributes. (Some already existed, e.g., __doc__ and
5757 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005758
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005759- Add -3 option to the interpreter to warn about features that are
5760 deprecated and will be changed/removed in Python 3.0.
5761
Georg Brandl2134e752007-05-21 20:34:16 +00005762- Patch #1686487: you can now pass any mapping after '**' in function
5763 calls.
5764
Collin Winter62903052007-05-18 23:11:24 +00005765- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005766 "except E as target:". This is to provide forwards compatibility
5767 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005768
Brett Cannon229cee22007-05-05 01:34:02 +00005769- Deprecate BaseException.message as per PEP 352.
5770
Georg Brandl3ee81df2008-05-17 18:14:43 +00005771- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005772 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005773
Vinay Sajip8549ce32007-05-06 17:53:37 +00005774- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005775 setting a plain string, ie don't expand to single letter identifiers.
5776
Raymond Hettinger13936692007-04-11 18:40:58 +00005777- Request #1191699: Slices can now be pickled.
5778
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005779- Request #1193128: str.translate() now allows a None argument for
5780 translations that only remove characters without re-mapping the
5781 remaining characters.
5782
Georg Brandl5cb76c12007-03-21 09:00:39 +00005783- Patch #1682205: a TypeError while unpacking an iterable is no longer
5784 masked by a generic one with the message "unpack non-sequence".
5785
Neal Norwitzaa754b72007-03-21 06:39:48 +00005786- Remove unused file Python/fmod.c.
5787
Guido van Rossum143b5642007-03-23 04:58:42 +00005788- Bug #1683368: The object.__init__() and object.__new__() methods are
5789 now stricter in rejecting excess arguments. The only time when
5790 either allows excess arguments is when it is not overridden and the
5791 other one is. For backwards compatibility, when both are
5792 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005793 warning later). Also, type.__init__() insists on the same signature
5794 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005795
Georg Brandl3ee81df2008-05-17 18:14:43 +00005796- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5797 object to complex using its __complex__() method before falling back
5798 to the __float__() method. Therefore, the functions in the cmath
5799 module now can operate on objects that define a __complex__()
5800 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005801
Georg Brandl3ee81df2008-05-17 18:14:43 +00005802- Patch #1623563: allow __class__ assignment for classes with
5803 __slots__. The old and the new class are still required to have the
5804 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005805
Georg Brandl3ee81df2008-05-17 18:14:43 +00005806- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00005809- Patch #1462488: Python no longer segfaults when
5810 ``object.__reduce_ex__()`` is called with an object that is faking
5811 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005812
Georg Brandl3ee81df2008-05-17 18:14:43 +00005813- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00005816- Patch #1444529: the builtin compile() now accepts keyword arguments.
5817
Georg Brandl7b9c5552007-03-12 14:30:05 +00005818- Bug #1678647: write a newline after printing an exception in any
5819 case, even when converting the value to a string failed.
5820
Georg Brandl871f1bc2007-03-12 13:17:36 +00005821- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005822 its argument, if it exists. If not, it will work like before. This
5823 allows customizing the output of dir() in the presence of a
5824 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005825
Collin Winter276887b2007-03-12 16:11:39 +00005826- Patch #922167: Python no longer segfaults when faced with infinitely
5827 self-recursive reload() calls (as reported by bug #742342).
5828
Georg Brandl3ee81df2008-05-17 18:14:43 +00005829- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005832- Patch #1491866: change the complex() constructor to allow
5833 parthensized forms. This means complex(repr(x)) now works instead of
5834 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005835
Georg Brandlaa2321b2007-03-07 00:40:28 +00005836- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005837 makes the filenames the warning module prints much more sensible
5838 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005839
Georg Brandl49aafc92007-03-07 00:34:46 +00005840- Variant of patch #697613: don't exit the interpreter on a SystemExit
5841 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005842 variable is given, but break into the interactive interpreter just
5843 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005848- Bug #1674503: close the file opened by execfile() in an error
5849 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005850
Georg Brandl0fca97a2007-03-05 22:28:08 +00005851- Patch #1674228: when assigning a slice (old-style), check for the
5852 sq_ass_slice instead of the sq_slice slot.
5853
Georg Brandl3ee81df2008-05-17 18:14:43 +00005854- When printing an unraisable error, don't print exceptions. before
5855 the name. This duplicates the behavior whening normally printing

Facundo Batistad918a652007-04-24 13:54:38 +00006347- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006348 the client's request was successfully received, understood, and
6349 accepted. Now in these cases no error is raised in urllib (issue
6350 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006358- Added a timeout parameter to the constructor of other protocols
6359 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6360 work started with create_connection() and timeout in httplib, and
6361 closes patch #723312.
6362
Vinay Sajip8549ce32007-05-06 17:53:37 +00006363- Patch #1676823: Added create_connection() to socket.py, which may be
6364 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006365 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006366
Martin v. Löwis0af33882007-03-23 13:27:15 +00006367- Bug #978833: Revert r50844, as it broke _socketobject.dup.

6387
Georg Brandlf66b6032007-03-14 08:27:52 +00006388- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006389 AttributeError instead of an IOError when the server's response
6390 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006391
Georg Brandl3ee81df2008-05-17 18:14:43 +00006392- Patch #957650: "%var%" environment variable references are now
6393 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00006396- Patch #1429539: pdb now correctly initializes the __main__ module
6397 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006398 correctly now.
6399

6406
Georg Brandl3ee81df2008-05-17 18:14:43 +00006407- Patch #1530482: add pydoc.render_doc() which returns the

6417 parameter which can be set to False to prevent the default
6418 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00006420- Patch #1581073: add a flag to textwrap that prevents the dropping of
6421 whitespace while wrapping.
6422
Georg Brandl92a6bae2007-03-13 17:43:32 +00006423- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006424 are set for invalid interpolation sequences that would lead to
6425 errors on reading back those values.

6465 Python would crash instead of raising an error.
6466

6468 returned string up to the first NUL character.
6469

6479
Georg Brandl3ee81df2008-05-17 18:14:43 +00006480- unittest now verifies more of its assumptions. In particular,
6481 TestCase and TestSuite subclasses (not instances) are no longer
6482 accepted in TestSuite.addTest(). This should cause no
6483 incompatibility since it never made sense with ordinary subclasses
6484 -- the failure just occurred later, with a more cumbersome
6485 exception.

6494 given a unicode argument and os.listdir() returns unicode filenames.
6495
Georg Brandl3ee81df2008-05-17 18:14:43 +00006496- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006874 time so that opening a database previously created with the DB_DUP
6875 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6876 opens. Specifically: dictionary assignment to a DB object will
6877 replace all values for a given key when the database allows
6878 duplicate values. DB users should use DB.put(k, v) when they want
6879 to store duplicates; not DB[k] = v.

6886 characters with ASCII value less than 32. Also, it correctly quotes
6887 dots only if they occur on a single line, as opposed to the previous
6888 behavior of quoting dots if they are the second character of any
6889 line.
