457 Decimal operation raises multiple signals and more than one of those
458 signals is trapped, the specification determines the order in which
459 the signals should be handled. In many cases this order wasn't
460 being followed, leading to the wrong Python exception being raised.

1844What's New in Python 2.6.1
1845==========================
1846
1847*Release date: 04-Dec-2008*
1848
1849Core and Builtins
1850-----------------
1851
1852- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1853 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1854 instead of throwing a MemoryError.
1855
1856- Issue #4367: Python would segfault during compiling when the unicodedata
1857 module couldn't be imported and \N escapes were present.
1858
1859- Issue #4348: Some bytearray methods returned that didn't cause any change to
1860 the bytearray, returned the same bytearray instead of a copy.
1861
1862- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1863
1864- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1865
1866- Issue #4048: The parser module now correctly validates relative imports.
1867
1868- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1869 exec statement.
1870
1871- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1872 method does not return iterators for the 4th and 5th items.
1873
1874- Issue #4209: Enabling unicode_literals and the print_function in the same
1875 __future__ import didn't work.
1876
1877- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1878 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1879 really executed because I cannot move to such directory on win2k)
1880
1881- Issue #4069: When set.remove(element) is used with a set element, the element
1882 is temporarily replaced with an equivalent frozenset. But the eventual
1883 KeyError would always report the empty frozenset([]) as the missing key. Now
1884 it correctly refers to the initial element.
1885
1886- Fixed C99 style comments in several files. Python is now C89 compatible
1887 again.

2035
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002036- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2037 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2038 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2039 ``printf`` function, whereas PyString_FromFormat has an independent
2040 implementation and uses "%zd" on all platforms for size_t values.
2041 This makes a difference on win64, where ``printf`` needs "%Id" to display
2042 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002044- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2048 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002052- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002059 was correctly parsed but parsing of subsequent arguments failed.
2060
Vinay Sajip35e3b032008-09-01 14:33:59 +00002061- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002062 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2063 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2064 when given a tuple of classes as second argument, were looking up
2065 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2066 type object.
2067

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002202What's New in Python 2.6 beta 3?
2203================================
2204
Barry Warsaw07a4a382008-08-21 01:15:08 +00002205*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002206
2207Core and Builtins
2208-----------------
2209
Guido van Rossumf8402962008-08-20 15:01:50 +00002210- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2211 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2212 extensions do not automatically benefit from the class attribute
2213 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2214 to their tp_flags field if they care. This is a backwards
2215 compatibility feature; in 3.0, all types will use the cache by
2216 default.
2217
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002218- Keyword arguments can now follow starred arguments. (``f(a, *args,
2219 keyword=23)`` is now valid syntax.)
2220
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002221- ctypes function pointers that are COM methods have a boolean True
2222 value again.
2223
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002224- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2225 by denying s# to parse objects that have a releasebuffer procedure,
2226 and introducing s*.
2227
Georg Brandl1e13ea92008-08-11 09:07:59 +00002228- Issue #3537: Fix an assertion failure when an empty but presized dict
2229 object was stored in the freelist.
2230
Mark Dickinsonb6467572008-08-04 21:30:09 +00002231- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2232 ValueError consistently across platforms.
2233
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002234- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2235 (64bit Unix, for example), unichr() would truncate its argument and return
2236 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2237
Neal Norwitze7d8be82008-07-31 17:17:14 +00002238- Apply security patches from Apple.
2239
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002240- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2241 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2242
Antoine Pitrou92f82162008-07-25 22:22:08 +00002243- Issue #1819: function calls with several named parameters are now on
2244 average 35% faster (as measured by pybench).
2245
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002246- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2247 the python debugger steps into a class statement: the free variables (local
2248 variables defined in an outer scope) would be deleted from the outer scope.
2249
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002250- Issue #2620: Overflow checking when allocating or reallocating memory
2251 was not always being done properly in some python types and extension
2252 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2253 all been updated to perform better checks and places in the code that
2254 would previously leak memory on the error path when such an allocation
2255 failed have been fixed.
2256
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002257Library
2258-------
2259
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002260- Issue #3612: Added some missing basic types in ctypes.wintypes.
2261
Benjamin Petersone977ad42008-08-20 01:42:01 +00002262- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2263 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2264
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002265- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2266 version reported by these tools does not necessarily follow the python
2267 version numbering scheme, so the module is less strict when parsing it.
2268
Nick Coghlanf70385a2008-08-18 12:42:46 +00002269- Issue #2235: Added Py3k warnings for types which will become unhashable
2270 under the stricter __hash__ inheritance rules in 3.0. Several types
2271 which did not meet the rules for hash invariants and were already
2272 unhashable in 3.0 have now been explicitly flagged as unhashable in
2273 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2274 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2275
Brett Cannon88f801d2008-08-18 00:46:22 +00002276- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2277 imported into the module but exposed as part of the module's API.
2278
Brett Cannon7b96f072008-08-18 00:41:11 +00002279- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2280
Brett Cannon46225e72008-08-18 00:36:52 +00002281- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2282
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002283- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2284
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002285- Issue #3575: Incremental decoder's decode function now takes bytearray
2286 by using 's*' instead of 't#'.
2287
Jesus Cea585ad8a2009-07-02 15:37:21 +00002288- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002289 fails unicode conversion on 2nd parameter. (windows only)
2290
Georg Brandl21896072010-08-01 22:31:28 +00002291- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00002292 in a redirect.
2293
Brett Cannonabe423e2008-08-16 21:47:07 +00002294- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002295 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002296
Facundo Batistaeb90b782008-08-16 14:44:07 +00002297- Issue #2776: fixed small issue when handling an URL with double slash
2298 after a 302 response in the case of not going through a proxy.
2299
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002300- Issue #2676: in the email package, content-type parsing was hanging on
2301 pathological input because of quadratic or exponential behaviour of a
2302 regular expression.
2303
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002304- Issue #3476: binary buffered reading through the new "io" library is now
2305 thread-safe.
2306
Brett Cannonbf3157b2008-08-14 05:00:03 +00002307- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2308 since mimetools itself is deprecated. Because modules are cached, all
2309 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2310
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002311- Issue #3134: shutil referenced undefined WindowsError symbol.
2312
Robert Schuppenies14646332008-08-10 11:01:53 +00002313- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2314 menu entries were not deleted.
2315
Brett Cannon83e81842008-08-09 23:30:55 +00002316- Copied the implementation of reduce() to _functools.reduce() to have a
2317 version that did not raise a DeprecationWarning under -3.
2318
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002319- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2320 a MemoryError rather than silently stop the iteration.
2321
Guido van Rossum59ce9012008-08-09 14:55:34 +00002322- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2323 to _sre.compile() will now be rejected. This should not affect anybody
2324 since the re.compile() function never generates invalid re-bytecode.
2325
Skip Montanaroa032bf42008-08-08 22:52:51 +00002326- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2327 upon first access it can be automatically initialized from the csv file if
2328 it wasn't initialized during instantiation.
2329
Brett Cannon3aa2a492008-08-06 22:28:09 +00002330- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2331 the reload() built-in has been removed.
2332
Brett Cannon7e30b672008-08-04 21:52:25 +00002333- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002334 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00002335 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
2336 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2337 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2338 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2339 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002340
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002341- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2342 raised an AttributeError.
2343
Benjamin Peterson01a24322008-07-28 23:35:27 +00002344- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002345 asking for a specific length. This problem only affected files opened
2346 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002347
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002348- Issue #3449: Update decimal module to use most recent specification
2349 (v. 1.68) and tests (v. 2.58) from IBM.
2350
Georg Brandl21896072010-08-01 22:31:28 +00002351- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

2355
Georg Brandlf9efabb2008-07-23 15:16:45 +00002356- Deprecate the "ast" parser function aliases.
2357
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002358- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
2359
2360- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2361 invalid arguments.
2362
2363- Issue #3302: Fix several crashes when calling locale's gettext functions
2364 with None arguments.
2365
2366- Issue #3389: Allow resolving dotted names for handlers in logging
2367 configuration files.
2368

2370
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002371- Issue #3394: zipfile.writestr sets external attributes when passed a
2372 file name rather than a ZipInfo instance, so files are extracted with
2373 mode 0600 rather than 000 under Unix.
2374
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002375- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2376 argument in python 2.5, this broke code that subclassed Popen to include its
2377 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2385-------------
2386
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002387- Issue #2235: the C API function PyObject_HashNotImplemented and its
2388 interaction with the tp_hash slot (added in 2.6b2) are now documented
2389
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002390- Issue #643841: The language reference now provides more detailed
2391 coverage of the lookup process for special methods. The disclaimers
2392 regarding lack of coverage of new-style classes have also been
2393 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002396What's New in Python 2.6 beta 2?
2397================================
2398
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002399*Release date: 17-Jul-2008*
2400
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002401Core and Builtins
2402-----------------
2403
Georg Brandl3e483f62008-07-16 22:57:41 +00002404- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2405 its methods now allow for items objects that can be converted to
2406 an integer using operator.index().
2407
Mark Dickinson64b7e502008-07-16 09:40:03 +00002408- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2409 produced a ValueError instead of giving the correct float.
2410
Eric Smitha5fa5a22008-07-16 00:11:49 +00002411- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2412 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2413
Mark Dickinson7103aa42008-07-15 19:08:33 +00002414- Issue #3008: the float type has a new instance method 'float.hex'
2415 and a new class method 'float.fromhex' to convert floating-point
2416 numbers to and from hexadecimal strings, respectively.
2417
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002418- Issue #2235: __hash__ is once again inherited by default. To allow
2419 collections.Hashable to remain meaningful in the presence of the
2420 default hash implementation (object.__hash__), it is now possible
2421 to explicit block inheritance of hash by setting __hash__=None at
2422 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2423 level.
2424
Nick Coghlanb028f502008-07-13 14:52:36 +00002425- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2426 the parent module cannot be found while performing an absolute import.
2427 This means that an incorrectly defined __package__ attribute will
2428 now only prevent relative imports in that module rather than causing
2429 all imports from that module to fail.
2430
Nick Coghlan14ff9942008-07-08 14:21:42 +00002431- Issue #2517: Allow unicode messages in Exceptions again by correctly
2432 bypassing the instance dictionary when looking up __unicode__ on
2433 new-style classes.
2434
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002435- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2436 set to a custom object whose write() method happens to install
2437 another file in sys.stdout.
2438
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002439- Issue #3088: Corrected a race condition in classes derived from
2440 threading.local: the first member set by a thread could be saved in
2441 another thread's dictionary.
2442
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002443- Issue #3004: Minor change to slice.indices(): the start and stop
2444 arguments are now treated identically, making the behaviour easier
2445 to describe and understand. For example, slice(None, -10,
2446 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2447 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2448 10, -1).
2449
Georg Brandl278fc502008-07-19 12:46:12 +00002450- Issue #3219: Calling a function with repeated keyword arguments,
2451 f(a=2, a=23), would not cause a syntax error. This was a regression

Georg Brandl5cc774e2008-06-11 20:28:06 +00002902 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002903
2904 This is controlled by the configure argument ``--with-universal-archs``:
2905
2906 - ``--with-universal-archs=all``: install 4-way universal
2907
2908 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2909
2910 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2911

2951 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002964- Issue #1631171: Re-implement the 'warnings' module in C (the
2965 original Python code has been kept as backup). This will allow for
2966 using the 'warning's machinery in such places as the parser where
2967 use of pure Python code is not possible. Both the ``showarning()``
2968 and ``formatwarning()`` gain an optional 'line' argument which is
2969 not called by default for backwards-compatibility reasons. Setting
2970 ``warnings.showwarning()`` to an implementation that lacks support
2971 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003034- Issue #2550: The approach used by client/server code for obtaining
3035 ports to listen on in network-oriented tests has been refined in an
3036 effort to facilitate running multiple instances of the entire
3037 regression test suite in parallel without issue.
3038 test_support.bind_port() has been fixed such that it will always
3039 return a unique port -- which wasn't always the case with the
3040 previous implementation, especially if socket options had been set
3041 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3042 new implementation of bind_port() will actually raise an exception
3043 if it is passed an AF_INET/SOCK_STREAM socket with either the
3044 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3045 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3046 the socket it's been passed. This currently only applies to
3047 Windows. This option prevents any other sockets from binding to the
3048 host/port we've bound to, thus removing the possibility of the
3049 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3050 when a second SOCK_STREAM socket binds and accepts to a host/port
3051 that's already been bound by another socket. The optional preferred
3052 port parameter to bind_port() has been removed. Under no
3053 circumstances should tests be hard coding ports!
3054
3055 test_support.find_unused_port() has also been introduced, which will
3056 pass a temporary socket object to bind_port() in order to obtain an
3057 unused port. The temporary socket object is then closed and
3058 deleted, and the port is returned. This method should only be used
3059 for obtaining an unused port in order to pass to an external program
3060 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3061 a parameter to a server-oriented class that doesn't give you direct
3062 access to the underlying socket used.
3063
3064 Finally, test_support.HOST has been introduced, which should be used
3065 for the host argument of any relevant socket calls (i.e. bind and
3066 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003067
3068 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003069 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003070 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3071 test_asynchat and test_socket_ssl.
3072
Georg Brandl3ee81df2008-05-17 18:14:43 +00003073 It is now possible for multiple instances of the regression test
3074 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00003353- Added the future_builtins module, which contains hex() and oct().
3354 These are the PEP 3127 version of these functions, designed to be
3355 compatible with the hex() and oct() builtins from Python 3.0. They
3356 differ slightly in their output formats from the existing, unchanged
3357 Python 2.6 builtins. The expected usage of the future_builtins
3358 module is:
3359 from future_builtins import hex, oct
3360
Eric Smith7ef40bf2008-02-20 23:34:22 +00003361- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3362 exponents for exponents with absolute value < 100. Follows C99
3363 standard. This is a change on Windows, which would use 3 digits.
3364 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3365 so that any alterations it does to the resulting string will be
3366 available in stringlib/formatter.h (for float.__format__).
3367
Eric Smith5a3c1352008-02-19 13:21:56 +00003368- Implemented PEP 3101, Advanced String Formatting. This adds a new
3369 builtin format(); a format() method for str and unicode; a
3370 __format__() method to object, str, unicode, int, long, float, and
3371 datetime; the class string.Formatter; and the C API
3372 PyObject_Format().
3373
Georg Brandl3ee81df2008-05-17 18:14:43 +00003374- Fixed several potential crashes, all caused by specially crafted
3375 __del__ methods exploiting objects in temporarily inconsistent
3376 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003377
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003378- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003379 prevent a possible crash: an Abstract Base Class would try to access
3380 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003381

Georg Brandl3ee81df2008-05-17 18:14:43 +00003385- Clear all free lists during a gc.collect() of the highest generation
3386 in order to allow pymalloc to free more arenas. Python may give back
3387 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003388
Georg Brandl3ee81df2008-05-17 18:14:43 +00003389- Issue #2045: Fix an infinite recursion triggered when printing a
3390 subclass of collections.defaultdict, if its default_factory is set
3391 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003392
Christian Heimesf75dbef2008-02-08 00:11:31 +00003393- Fixed a minor memory leak in dictobject.c. The content of the free
3394 list was not freed on interpreter shutdown.
3395
Georg Brandl5a7eca12010-03-21 19:29:04 +00003396- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003397 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003398
Georg Brandl3ee81df2008-05-17 18:14:43 +00003399- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3400 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003401 to compact the internal free lists of pre-allocted ints and floats.
3402
Georg Brandl3ee81df2008-05-17 18:14:43 +00003403- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3404 calls. Python expected the return type int but the fork familie
3405 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003406
Georg Brandl3ee81df2008-05-17 18:14:43 +00003407- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003419- Patch #1473257: generator objects gain a gi_code attribute. This is
3420 the same object as the func_code attribute of the function that
3421 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003422
Georg Brandl3ee81df2008-05-17 18:14:43 +00003423- Issue #1920: "while 0" statements were completely removed by the
3424 compiler, even in the presence of an "else" clause, which is
3425 supposed to be run when the condition is false. Now the compiler
3426 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003427
Guido van Rossumeead05f2008-01-24 18:21:02 +00003428- A few crashers fixed: weakref_in_del.py (issue #1377858);
3429 loosing_dict_ref.py (issue #1303614, test67.py);
3430 borrowed_ref_[34].py (not in tracker).
3431
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003432- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003433 suppressed while an extension is loaded by calling SetErrorMode in
3434 dynload_win.c. The error is still reported properly.
3435
Georg Brandl3ee81df2008-05-17 18:14:43 +00003436- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003437 several extension methods and modules do not work without unicode
3438 support.
3439
Georg Brandl26543b12008-01-21 18:36:51 +00003440- Issue #1882: when compiling code from a string, encoding cookies in the
3441 second line of code were not always recognized correctly.
3442
Georg Brandl14404b62008-01-19 19:27:05 +00003443- Issue #1679: "0x" was taken as a valid integer literal.
3444
Georg Brandl6caad7d2008-01-26 14:19:22 +00003445- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003446 added.
3447
Christian Heimesc94e2b52008-01-14 04:13:37 +00003448- sys.float_info / PyFloat_GetInfo: The floating point information
3449 object was converted from a dict to a specialized structseq object.
3450
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451- Patch #1816: Added sys.flags structseq. It exposes the status of
3452 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003453
Georg Brandl3ee81df2008-05-17 18:14:43 +00003454- Objects/structseq.c: Implemented new structseq representation. The
3455 patch makes structseqs (e.g. the return value of os.stat) more
3456 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003457
Georg Brandl3ee81df2008-05-17 18:14:43 +00003458- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003480 and INF. float("nan"), float("inf") and float("-inf") now work on
3481 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003482
Georg Brandl3ee81df2008-05-17 18:14:43 +00003483- Compiler now generates simpler and faster code for dictionary
3484 literals. The oparg for BUILD_MAP now indicates an estimated
3485 dictionary size. There is a new opcode, STORE_MAP, for adding
3486 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003515- Patch #1739468: Directories and zipfiles containing a __main__.py
3516 file can now be directly executed by passing their name to the
3517 interpreter. The directory/zipfile is automatically inserted as the
3518 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003520- Issue #1265: Fix a problem with sys.settrace, if the tracing
3521 function uses a generator expression when at the same time the
3522 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003523
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003524- sets and frozensets now have an isdisjoint() method.
3525

3527
Neal Norwitz44f326e2007-10-05 05:29:17 +00003528- Fix warnings found by the new version of the Coverity checker.
3529
Georg Brandl5a7eca12010-03-21 19:29:04 +00003530- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003531 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3532 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003533
Georg Brandl3ee81df2008-05-17 18:14:43 +00003534- Issue #1686386: Tuple's tp_repr did not take into account the
3535 possibility of having a self-referential tuple, which is possible
3536 from C code. Nor did object's tp_str consider that a type's tp_str
3537 could do something that could lead to an inifinite recursion.
3538 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3539 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003540
Georg Brandl3ee81df2008-05-17 18:14:43 +00003541- Issue #1164: It was possible to trigger deadlock when using the
3542 'print' statement to write to a file since the GIL was not released
3543 as needed. Now PyObject_Print() does the right thing along with
3544 various tp_print implementations of the built-in types and those in
3545 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003546
Georg Brandl3ee81df2008-05-17 18:14:43 +00003547- Issue #1147: Exceptions were directly allowing string exceptions in
3548 their throw() method even though string exceptions no longer
3549 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003550
Georg Brandl3ee81df2008-05-17 18:14:43 +00003551- Issue #1096: Prevent a segfault from getting the repr of a very
3552 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003553
Brett Cannon1e534b52007-09-07 04:18:30 +00003554- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003555 PyObject_Call() never calling back out to Python code to trigger
3556 recursion depth updates/checks. Required the creation of a static
3557 RuntimeError instance in case normalizing an exception put the
3558 recursion check value past its limit. Fixes crashers
3559 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003560
Georg Brandl3ee81df2008-05-17 18:14:43 +00003561- Patch #1031213: Decode source line in SyntaxErrors back to its

Georg Brandla5ea6892007-06-01 11:33:33 +00003573
Neal Norwitz0ac60192007-05-27 04:08:54 +00003574- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003575 __*__ attributes. (Some already existed, e.g., __doc__ and
3576 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003577
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003578- Add -3 option to the interpreter to warn about features that are
3579 deprecated and will be changed/removed in Python 3.0.
3580
Georg Brandl2134e752007-05-21 20:34:16 +00003581- Patch #1686487: you can now pass any mapping after '**' in function
3582 calls.
3583
Collin Winter62903052007-05-18 23:11:24 +00003584- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003585 "except E as target:". This is to provide forwards compatibility
3586 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003587
Brett Cannon229cee22007-05-05 01:34:02 +00003588- Deprecate BaseException.message as per PEP 352.
3589
Georg Brandl3ee81df2008-05-17 18:14:43 +00003590- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003591 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003592
Vinay Sajip8549ce32007-05-06 17:53:37 +00003593- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003594 setting a plain string, ie don't expand to single letter identifiers.
3595
Raymond Hettinger13936692007-04-11 18:40:58 +00003596- Request #1191699: Slices can now be pickled.
3597
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003598- Request #1193128: str.translate() now allows a None argument for
3599 translations that only remove characters without re-mapping the
3600 remaining characters.
3601
Georg Brandl5cb76c12007-03-21 09:00:39 +00003602- Patch #1682205: a TypeError while unpacking an iterable is no longer
3603 masked by a generic one with the message "unpack non-sequence".
3604
Neal Norwitzaa754b72007-03-21 06:39:48 +00003605- Remove unused file Python/fmod.c.
3606
Guido van Rossum143b5642007-03-23 04:58:42 +00003607- Bug #1683368: The object.__init__() and object.__new__() methods are
3608 now stricter in rejecting excess arguments. The only time when
3609 either allows excess arguments is when it is not overridden and the
3610 other one is. For backwards compatibility, when both are
3611 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003612 warning later). Also, type.__init__() insists on the same signature
3613 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003614
Georg Brandl3ee81df2008-05-17 18:14:43 +00003615- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3616 object to complex using its __complex__() method before falling back
3617 to the __float__() method. Therefore, the functions in the cmath
3618 module now can operate on objects that define a __complex__()
3619 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003620
Georg Brandl3ee81df2008-05-17 18:14:43 +00003621- Patch #1623563: allow __class__ assignment for classes with
3622 __slots__. The old and the new class are still required to have the
3623 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003624

3629 ``object.__reduce_ex__()`` is called with an object that is faking
3630 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003631
Georg Brandl3ee81df2008-05-17 18:14:43 +00003632- Patch #1680015: Don't modify __slots__ tuple if it contains an

3636
Georg Brandl7b9c5552007-03-12 14:30:05 +00003637- Bug #1678647: write a newline after printing an exception in any
3638 case, even when converting the value to a string failed.
3639
Georg Brandl871f1bc2007-03-12 13:17:36 +00003640- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003641 its argument, if it exists. If not, it will work like before. This
3642 allows customizing the output of dir() in the presence of a
3643 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003644
Collin Winter276887b2007-03-12 16:11:39 +00003645- Patch #922167: Python no longer segfaults when faced with infinitely
3646 self-recursive reload() calls (as reported by bug #742342).
3647
Georg Brandl3ee81df2008-05-17 18:14:43 +00003648- Patch #1675981: remove unreachable code from ``type.__new__()``
3649 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003651- Patch #1491866: change the complex() constructor to allow
3652 parthensized forms. This means complex(repr(x)) now works instead of
3653 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003654
Georg Brandlaa2321b2007-03-07 00:40:28 +00003655- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003656 makes the filenames the warning module prints much more sensible
3657 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003658
Georg Brandl49aafc92007-03-07 00:34:46 +00003659- Variant of patch #697613: don't exit the interpreter on a SystemExit
3660 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003661 variable is given, but break into the interactive interpreter just
3662 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003667- Bug #1674503: close the file opened by execfile() in an error
3668 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003669
Georg Brandl0fca97a2007-03-05 22:28:08 +00003670- Patch #1674228: when assigning a slice (old-style), check for the
3671 sq_ass_slice instead of the sq_slice slot.
3672
Georg Brandl3ee81df2008-05-17 18:14:43 +00003673- When printing an unraisable error, don't print exceptions. before
3674 the name. This duplicates the behavior whening normally printing
3675 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003676
Georg Brandl3ee81df2008-05-17 18:14:43 +00003677- Bug #1653736: Properly discard third argument to

4303 -- the failure just occurred later, with a more cumbersome
4304 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004585- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4586 with RFC 3207 and forgets any knowledge obtained from the server not
4587 obtained from the TLS negotiation itself. Patch contributed by Bill
4588 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004589
Georg Brandl3ee81df2008-05-17 18:14:43 +00004590- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004591 that the SMTP.starttls() caller no longer needs to call ehlo()
4592 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004593 does not claim to support starttls. Adds the
4594 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4675 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4676 silently miscode subclasses of those types. Now, it raises a
4677 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004678

Georg Brandl3ee81df2008-05-17 18:14:43 +00004693 time so that opening a database previously created with the DB_DUP
4694 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4695 opens. Specifically: dictionary assignment to a DB object will
4696 replace all values for a given key when the database allows
4697 duplicate values. DB users should use DB.put(k, v) when they want
4698 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004699

4705 characters with ASCII value less than 32. Also, it correctly quotes
4706 dots only if they occur on a single line, as opposed to the previous
4707 behavior of quoting dots if they are the second character of any
4708 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004709

Georg Brandl3ee81df2008-05-17 18:14:43 +00004978 periodic threadstate and signal checking in tight loops. By
4979 default, this option is turned-off. It should only be enabled in
4980 debugged, performance critical applications.

5032
Georg Brandl3ee81df2008-05-17 18:14:43 +00005033- Unified naming convention for free lists and their limits. All free
5034 lists in Object/ are named ``free_list``, the counter ``numfree``

5036 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005037
Georg Brandl3ee81df2008-05-17 18:14:43 +00005038- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5039 to ``PyTuple_SetItem``, it can be used to populate a brand new
5040 frozenset; but it does not steal a reference to the added item.

5052
Georg Brandl3ee81df2008-05-17 18:14:43 +00005053- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5054 of w# format code incorrectly truncated the length to an int, even
5055 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5056 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005057
Georg Brandl3ee81df2008-05-17 18:14:43 +00005058- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5078
5079- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5080 outside of pystate.c and should not be necessary.
5081
Georg Brandl3ee81df2008-05-17 18:14:43 +00005082- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5083 absolute imports. In earlier versions they might have used relative
5084 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005085
Georg Brandl3ee81df2008-05-17 18:14:43 +00005086- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5087 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005088
Georg Brandl3ee81df2008-05-17 18:14:43 +00005089- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005114- Removed the macfs module. It had been deprecated since Python 2.5.
5115 This lead to the deprecation of macostools.touched() as it relied
