| ================================ |
| |
| *Release date: 2010-08-03* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #6213: Implement getstate() and setstate() methods of utf-8-sig and |
| utf-16 incremental encoders. |
| |
| - Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the |
| start byte and the continuation byte(s) are now considered invalid, instead |
| of the number of bytes specified by the start byte. |
| E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and |
| replaces with U+FFFD only the start byte ('\xf1') and the continuation byte |
| ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence. |
| Previous versions returned a single u'\ufffd'. |
| |
| - Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError. |
| |
| - Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash |
| the interpreter with characters outside the Basic Multilingual Plane |
| (higher than 0x10000). |
| |
| - Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of |
| __hash__ in 3.x" warning. Also fix "XXX undetected error" that |
| arises from the "Overriding __eq__ blocks inheritance ..." warning |
| when turned into an exception: in this case the exception simply |
| gets ignored. |
| |
| - Issue #4108: In urllib.robotparser, if there are multiple 'User-agent: *' |
| entries, consider the first one. |
| |
| - Issue #9354: Provide getsockopt() in asyncore's file_wrapper. |
| |
| - In the unicode/str.format(), raise a ValueError when indexes to arguments are |
| too large. |
| |
| - Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding |
| and error handler, instead of writing to the C stderr file in utf-8 |
| |
| - Issue #7902: When using explicit relative import syntax, don't try |
| implicit relative import semantics. |
| |
| - Issue #7079: Fix a possible crash when closing a file object while using |
| it from another thread. Patch by Daniel Stutzbach. |
| |
| - Issue #1533: fix inconsistency in range function argument |
| processing: any non-float non-integer argument is now converted to |
| an integer (if possible) using its __int__ method. Previously, only |
| small arguments were treated this way; larger arguments (those whose |
| __int__ was outside the range of a C long) would produce a TypeError. |
| |
| - Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize |
| is passed to bytearray. |
| |
| - Issue #8329: Don't return the same lists from select.select when no fds are |
| changed. |
| |
| - Raise a TypeError when trying to delete a T_STRING_INPLACE struct member. |
| |
| - Issue #1583863: An unicode subclass can now override the __unicode__ method. |
| |
| - Issue #7507: Quote "!" in pipes.quote(); it is special to some shells. |
| |
| - Issue #7544: Preallocate thread memory before creating the thread to avoid |
| a fatal error in low memory condition. |
| |
| - Issue #7820: The parser tokenizer restores all bytes in the right if |
| the BOM check fails. |
| |
| - Issue #7072: isspace(0xa0) is true on Mac OS X |
| |
| C-API |
| ----- |
| |
| - Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows |
| embedders of the interpreter to set sys.argv without also modifying |
| sys.path. This helps fix `CVE-2008-5983 |
| <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_. |
| |
| Library |

| the interpreter executable. This fixes a failure of test_httpservers |
| on OS X. |

| mode doesn't add a BOM at the end of the file if the file isn't empty. |
| |
| - Issue #3704: cookielib was not properly handling URLs with a / in the |
| parameters. |
| |
| - Issue #4629: getopt raises an error if an argument ends with = whereas getopt |

| options). |
| |
| - Issue #7895: platform.mac_ver() no longer crashes after calling os.fork() |
| |
| - Issue #5395: array.fromfile() would raise a spurious EOFError when an |

| returns the same information as the id command. |
| |
| os.getgroups() can now return more than 16 groups on MacOSX. |
| |
| - Issue #9277: Fix bug in struct.pack for bools in standard mode |
| (e.g., struct.pack('>?')): if conversion to bool raised an exception |
| then that exception wasn't properly propagated on machines where |
| char is unsigned. |
| |
| - Issue #7384: If the system readline library is linked against |

| effectively raised. A new private utility ``_check_py3k_warnings`` has been |
| backported to help silencing py3k warnings. |
| |
| - Issue #8672: Add a zlib test ensuring that an incomplete stream can be |
| handled by a decompressor object without errors (it returns incomplete |
| uncompressed data). |
| |
| - Issue #8629: Disable some test_ssl tests, since they give different |
| results with OpenSSL 1.0.0 and higher. |

| type is specified. Patch by Brian Curtin. |
| |
| - Issue #6939: Fix file I/O objects in the `io` module to keep the original |

| the release file is empty. |

| sys.dont_write_bytecode. |
| |

| reading from stdin so that existing input does not confuse it and |
| lead to incorrect entry or an IOError. It also properly flushes it |
| afterwards to avoid the terminal echoing the input afterwards on |
| OSes such as Solaris. |
| |
| - Issue #7244: itertools.izip_longest() no longer ignores exceptions |
| raised during the formation of an output tuple. |
| |
| - Issue #7233: Fix a number of two-argument Decimal methods to make |
| sure that they accept an int or long as the second argument. Also |
| fix buggy handling of large arguments (those with coefficient longer |

| |
| - Issue #7082: When falling back to the MIME 'name' parameter, the |

| |
| - Fix a problem in PyErr_NormalizeException that leads to "undetected errors" |
| when hitting the recursion limit under certain circumstances. |
| |
| - Issue #1665206: Remove the last eager import in _warnings.c and make it lazy. |
| |
| - Issue #4034: Fix weird attribute error messages of the traceback object. (As |
| a result traceback.__members__ no longer exists.) |
| |
| - Issue #5247: Improve error message when unknown format codes are |
| used when using str.format() with str, unicode, long, int, and |
| float arguments. |
| |
| - Running Python with the -3 option now also warns about classic division |
| for ints and longs. |
| |
| - Issue #5013: Fixed a bug in FileHandler which occurred when the delay |
| parameter was set. |
| |
| - Issue #1242657: the __len__() and __length_hint__() calls in several tools |
| were suppressing all exceptions. These include list(), filter(), map(), |
| zip(), and bytearray(). |
| |
| - Issue #4935: The overflow checking code in the expandtabs() method common |
| to str, bytes and bytearray could be optimized away by the compiler, letting |
| the interpreter segfault instead of raising an error. |
| |
| - Issue #4915: Port sysmodule to Windows CE. |
| |
| - Issue #1180193: When importing a module from a .pyc (or .pyo) file with |
| an existing .py counterpart, override the co_filename attributes of all |
| code objects if the original filename is obsolete (which can happen if the |
| file has been renamed, moved, or if it is accessed through different paths). |
| Patch by Ziga Seilnacht and Jean-Paul Calderone. |
| |
| - Issue #4075: Use OutputDebugStringW in Py_FatalError. |
| |
| - Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open |

| - Issue #4764: IOError.filename is set when trying to open a directory on POSIX |
| systems. |

| fail. |
| |
| - Issue #4597: Fixed several opcodes that weren't always propagating |
| exceptions. |
| |
| - Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always |
| print elapsed times, not only when some objects are uncollectable / |
| unreachable. Original patch by Neil Schemenauer. |
| |
| - Issue #4589: Fixed exception handling when the __exit__ function of a |
| context manager returns a value that cannot be converted to a bool. |
| |
| - Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` |
| method on file objects with closefd=False. The file descriptor is still |
| kept open but the file object behaves like a closed file. The ``FileIO`` |
| object also got a new readonly attribute ``closefd``. |
| |
| - Issue #3689: The list reversed iterator now supports __length_hint__ |
| instead of __len__. Behavior now matches other reversed iterators. |
| |
| - Issue #4509: Various issues surrounding resize of bytearray objects to |
| which there are buffer exports. |
| |
| - Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with |
| short file names. |

| defined (part of issue #5035). |

| output compared to previous Python versions. |
| |
| - Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop |

| |
| - Issue #2047: shutil.move() could believe that its destination path was |

| "src.new"). |
| |
| - Issue #4920: Fixed .next() vs .__next__() issues in the ABCs for |
| Iterator and MutableSet. |

| allow adding directories to a zipfile. |
| |
| - Issue #5008: When a file is opened in append mode with the new IO library, |
| do an explicit seek to the end of file (so that e.g. tell() returns the |
| file size rather than 0). This is consistent with the behaviour of the |
| traditional 2.x file object. |
| |
| - Issue #3997: zipfiles generated with more than 65536 files could not be |
| opened with other applications. |
| |
| - Issue #4816: itertools.combinations() and itertools.product were raising |

| - Issue #4201: pdb can now access and display source code loaded via |
| zipimport (or any other conformant PEP 302 loader). Original patch by |
| Alexander Belopolsky. |
| |
| - Issue #4197: doctests in modules loaded via zipimport (or any other PEP |
| 302 conformant loader) will now work correctly in most cases (they |
| are still subject to the constraints that exist for all code running |
| from inside a module loaded via a PEP 302 loader and attempting to |
| perform IO operations based on __file__). Original patch by |
| Alexander Belopolsky. |
| |
| - Issues #4082 and #4512: Add runpy support to zipimport in a manner that |
| allows backporting to maintenance branches. Original patch by |

| producing a ValueError on some platforms. |
| |
| - Restore Python 2.3 compatibility for decimal.py. |

| |
| What's New in Python 2.6.1 |

| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #3996: On Windows, the PyOS_CheckStack function would cause the |
| interpreter to abort ("Fatal Python error: Could not reset the stack!") |
| instead of throwing a MemoryError. |
| |
| - Issue #4367: Python would segfault during compiling when the unicodedata |
| module couldn't be imported and \N escapes were present. |
| |
| - Issue #4348: Some bytearray methods returned that didn't cause any change to |
| the bytearray, returned the same bytearray instead of a copy. |
| |
| - Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function. |
| |
| - Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly. |
| |
| - Issue #4048: The parser module now correctly validates relative imports. |

| - Issue #4225: ``from __future__ import unicode_literals`` didn't work in an |
| exec statement. |

| __future__ import didn't work. |

| really executed because I cannot move to such directory on win2k) |
| |
| - Issue #4069: When set.remove(element) is used with a set element, the element |
| is temporarily replaced with an equivalent frozenset. But the eventual |
| KeyError would always report the empty frozenset([]) as the missing key. Now |
| it correctly refers to the initial element. |

| What's New in Python 2.6 release candidate 2? |
| ============================================= |
| |
| *Release date: 17-Sep-2008* |
| |
| Core and Builtins |
| ----------------- |
| |
| Extension Modules |
| ----------------- |
| |
| - Security Issue #2: imageop did not validate arguments correctly and could |
| segfault as a result. |
| |
| - Issue #3886: Possible integer overflows in the _hashopenssl module were |
| closed. |
| |
| Tools/Demos |
| ----------- |
| |
| - Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise |
| AttributeError instead of RuntimeError, depending in which C API call |
| exactly the recursion limit is exceeded. Consequently, both exception types |
| are caught and silenced. |
| |
| Build |
| ----- |
| |
| - Issue #3617: Include a licensing statement regarding the Microsoft |
| C runtime in the Windows installer. |
| |
| |
| What's New in Python 2.6 release candidate 1? |
| ============================================= |
| |
| *Release date: 12-Sep-2008* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #3642: Suppress warning in obmalloc when size_t is larger than uint. |
| |
| - Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with |
| PyString_FromFormat or PyErr_Format to display size_t values. The macro |
| PY_FORMAT_SIZE_T is designed to select the correct format for the OS |
| ``printf`` function, whereas PyString_FromFormat has an independent |
| implementation and uses "%zd" on all platforms for size_t values. |
| This makes a difference on win64, where ``printf`` needs "%Id" to display |
| 64bit values. |
| |
| - Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on |
| error. |
| |
| - Issue #3777: long() applied to a float object now always return a long |
| object; previously an int would be returned for small values. the __long__ |
| method is allowed to return either an int or a long, but the behaviour of |
| float objects should not change to respect backward compatibility. |
| |
| - Issue #3751: str.rpartition would perform a left-partition when called with |
| a unicode argument. |
| |
| - Issue #3683: Fix compilation when --without-threads is given. |
| |
| - Issue #3668: Fix a memory leak with the "s*" argument parser in |
| PyArg_ParseTuple and friends, which occurred when the argument for "s*" |
| was correctly parsed but parsing of subsequent arguments failed. |
| |
| - Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to |
| match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__ |
| mechanism. In the process, fix a bug where isinstance() and issubclass(), |
| when given a tuple of classes as second argument, were looking up |
| __instancecheck__ / __subclasscheck__ on the tuple rather than on each |
| type object. |
| |
| - Fix crashes on memory allocation failure found with failmalloc. |
| |
| - Fix memory leaks found with valgrind and update suppressions file. |
| |
| - Fix compiler warnings in opt mode which would lead to invalid memory reads. |
| |
| - Fix problem using wrong name in decimal module reported by pychecker. |
| |
| - Silenced another compiler warning about a used but not defined |
| function 'stringlib_contains_obj'. |
| |
| - Added warnings on the use of ``__getslice__``, ``__setslice__``, or |
| ``__delslice__``. |
| |
| - Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared |
| library targets in the Makefile. |
| |
| - Issue #1204: The configure script now tests for additional libraries |
| that may be required when linking against readline. This fixes issues |
| with x86_64 builds on some platforms (a few Linux flavors and OpenBSD). |
| |
| C-API |
| ----- |
| |
| - Aliased PyObject_Bytes to PyObject_Str. |
| |
| Library |
| ------- |
| |
| - Issue #3640: Pickling a list or a dict uses less local variables, to reduce |
| stack usage in the case of deeply nested objects. |
| |
| - Issue #3629: Fix sre "bytecode" validator for an end case. |
| |
| - Issue #3811: The Unicode database was updated to 5.1. |
| |
| - Issue #3781: Further warnings.catch_warnings() cleanup to prevent |
| silent misbehaviour when a single instance is nested in multiple |
| with statements, or when the methods are invoked in the wrong order. |
| |
| - Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging. |
| |
| - Issue #3781: Clean up the API for warnings.catch_warnings() by having it |
| return a list or None rather than a custom object. |
| |
| - Issue #1638033: Cookie.Morsel gained the httponly attribute. |
| |
| - Issue #3535: zipfile couldn't read some zip files larger than 2GB. |
| |

| |
| - Issue #3762: platform.architecture() fails if python is lanched via |
| its symbolic link. |
| |
| - Issue #3772: Fixed regression problem in StreamHandler.emit(). |
| |
| - Issue #600362: Relocated parse_qs() and parse_qsl(), from the cgi module |
| to the urlparse one. Added a PendingDeprecationWarning in the old |
| module, it will be deprecated in the future. |
| |
| - Issue #2562: Fix distutils PKG-INFO writing logic to allow having |
| non-ascii characters and Unicode in setup.py meta-data. |
| |
| - Issue #3726: Allow spaces in separators in logging configuration files. |
| |
| - Issue #3719: platform.architecture() fails if there are spaces in the |
| path to the Python binary. |
| |
| - Issue #3602: Moved test.test_support.catch_warning() to |
| warnings.catch_warnings() along with some API cleanup. Expanding the tests |
| for catch_warnings() also led to an improvement in the raising of a |
| DeprecationWarning related to warnings.warn_explicit(). |
| |
| - The deprecation warnings for the old camelCase threading API were removed. |
| |
| - logging: fixed lack of use of encoding attribute specified on a stream. |
| |
| - Silenced a trivial compiler warning in the sqlite module. |
| |
| - Fixed two format strings in the _collections module. |
| |
| - Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a |
| directory. |
| |
| - Issue #3708: os.urandom no longer goes into an infinite loop when passed a |
| non-integer floating point number. |
| |
| - Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing |
| SEM_VALUE_MAX. |
| |
| Extension Modules |
| ----------------- |
| |
| - Issue #2975: When compiling several extension modules with Visual Studio 2008 |
| from the same python interpreter, some environment variables would grow |
| without limit. |
| |
| - Issue #3643: Added a few more checks to _testcapi to prevent segfaults by |
| exploitation of poor argument checking. |
| |
| - sqlite3: Changed docstring of iterdump() to mark method as "Non-standard". |
| |
| - Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all |
| remaining ones have "pysqlite_" prefix. |
| |
| - Issue #3846: Release the GIL during sqlite3_prepare calls. This improves |
| concurrent access to the same SQLite database from multiple |
| threads/processes. |
| |
| Tests |
| ----- |
| |
| - Issue #3781: Add test.test_support.check_warnings() as a convenience |
| wrapper for warnings.catch_warnings() that makes it easier to check |
| that expected warning messages are being reported. |
| |
| - Issue #3796: Some tests functions were not enabled in test_float. |
| |
| - Issue #3768: Move test_py3kwarn over to the new API for catch_warnings(). |
| |
| Build |
| ----- |
| |
| - Issue #3833: Use a different upgrade code for Win64 installers. |
| |
| - Issue #2271: Set SecureCustomProperties so that installation will properly |
| use the TARGETDIR even for unprivileged users. |
| |
| - Allow passing the MSI file name to merge.py. |
| |
| - Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash |
| with GNU build target guidelines. |
| |
| |
| What's New in Python 2.6 beta 3? |
| ================================ |
| |
| *Release date: 20-Aug-2008* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from |
| Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party |
| extensions do not automatically benefit from the class attribute |
| cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG |
| to their tp_flags field if they care. This is a backwards |
| compatibility feature; in 3.0, all types will use the cache by |
| default. |
| |
| - Keyword arguments can now follow starred arguments. (``f(a, *args, |
| keyword=23)`` is now valid syntax.) |
| |
| - ctypes function pointers that are COM methods have a boolean True |
| value again. |
| |
| - Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple, |
| by denying s# to parse objects that have a releasebuffer procedure, |
| and introducing s*. |
| |
| - Issue #3537: Fix an assertion failure when an empty but presized dict |
| object was stored in the freelist. |
| |
| - Issue #1481296: Make long(float('nan')) and int(float('nan')) raise |
| ValueError consistently across platforms. |
| |
| - Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long) |
| (64bit Unix, for example), unichr() would truncate its argument and return |
| u'\x00' for unichr(2**32). Now it properly raises an OverflowError. |
| |
| - Apply security patches from Apple. |
| |
| - Issue #2542: Now that issubclass() may call arbitrary code, ensure that |
| PyErr_ExceptionMatches returns 0 when an exception occurs there. |
| |
| - Issue #1819: function calls with several named parameters are now on |
| average 35% faster (as measured by pybench). |
| |
| - Issue #2378: An unexpected UnboundLocalError or NameError could appear when |
| the python debugger steps into a class statement: the free variables (local |
| variables defined in an outer scope) would be deleted from the outer scope. |
| |
| - Issue #2620: Overflow checking when allocating or reallocating memory |
| was not always being done properly in some python types and extension |
| modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have |
| all been updated to perform better checks and places in the code that |
| would previously leak memory on the error path when such an allocation |
| failed have been fixed. |
| |
| Library |
| ------- |
| |
| - Issue #3612: Added some missing basic types in ctypes.wintypes. |
| |
| - The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of |
| symtable.Symbol have been deprecated for removal in 3.0 and the next release. |
| |
| - Issue #2234: distutils failed for some versions of the cygwin compiler. The |
| version reported by these tools does not necessarily follow the python |
| version numbering scheme, so the module is less strict when parsing it. |
| |
| - Issue #2235: Added Py3k warnings for types which will become unhashable |
| under the stricter __hash__ inheritance rules in 3.0. Several types |
| which did not meet the rules for hash invariants and were already |
| unhashable in 3.0 have now been explicitly flagged as unhashable in |
| 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite, |
| xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList) |
| |
| - Update __all__ for cookielib, csv, os, urllib2, and weakref to include things |
| imported into the module but exposed as part of the module's API. |
| |
| - Remove an unneeded import of abc.ABCMeta from 'inspect'. |
| |
| - Remove unneeded imports of 'sys' and 'warnings' from 'io'. |
| |
| - Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread. |
| |
| - Issue #3575: Incremental decoder's decode function now takes bytearray |
| by using 's*' instead of 't#'. |
| |
| - Issue #2222: Fixed reference leak when occurred os.rename() |
| fails unicode conversion on 2nd parameter. (windows only) |
| |
| - Issue #2464: urllib2 now supports a malformation in the URL received |
| in a redirect. |
| |
| - Silence the DeprecationWarning raised when importing mimetools in |
| BaseHTTPServer, cgi (and rfc822), httplib. |
| |
| - Issue #2776: fixed small issue when handling an URL with double slash |
| after a 302 response in the case of not going through a proxy. |
| |
| - Issue #2676: in the email package, content-type parsing was hanging on |
| pathological input because of quadratic or exponential behaviour of a |
| regular expression. |
| |
| - Issue #3476: binary buffered reading through the new "io" library is now |
| thread-safe. |
| |
| - Silence the DeprecationWarning of rfc822 when it is imported by mimetools |
| since mimetools itself is deprecated. Because modules are cached, all |
| subsequent imports of rfc822 will not raise a visible DeprecationWarning. |
| |
| - Issue #3134: shutil referenced undefined WindowsError symbol. |
| |
| - Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to |
| menu entries were not deleted. |
| |
| - Copied the implementation of reduce() to _functools.reduce() to have a |
| version that did not raise a DeprecationWarning under -3. |
| |
| - Issue #3205: When iterating over a BZ2File fails allocating memory, raise |
| a MemoryError rather than silently stop the iteration. |
| |
| - Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode" |
| to _sre.compile() will now be rejected. This should not affect anybody |
| since the re.compile() function never generates invalid re-bytecode. |
| |
| - Issue #3436: Make csv.DictReader's fieldnames attribute a property so that |
| upon first access it can be automatically initialized from the csv file if |
| it wasn't initialized during instantiation. |
| |
| - Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as |
| the reload() built-in has been removed. |
| |
| - Changed code in the following modules/packages to remove warnings raised |
| while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb, |
| ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email, |
| filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile, |
| pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket, |
| subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap, |
| threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib. |
| |
| - Issue #3039: Fix tarfile.TarFileCompat.writestr() which always |
| raised an AttributeError. |
| |
| - Issue #2523: Fix quadratic behaviour when read()ing a binary file without |
| asking for a specific length. This problem only affected files opened |
| using the new "io" module, not the built-in open() function. |
| |
| - Issue #3449: Update decimal module to use most recent specification |
| (v. 1.68) and tests (v. 2.58) from IBM. |
| |
| - Issue #3437: Bug fix in robotparser parsing of Allow: lines. |
| |
| - Issue #1592: Improve error reporting when operations are attempted |
| on a closed shelf. |
| |
| - Deprecate the "ast" parser function aliases. |
| |
| - Issue #3120: On 64-bit Windows the subprocess module was truncating handles. |
| |
| - Issue #3303: Fix a crash in locale.strcoll() when calling it with |
| invalid arguments. |
| |
| - Issue #3302: Fix several crashes when calling locale's gettext functions |
| with None arguments. |
| |
| - Issue #3389: Allow resolving dotted names for handlers in logging |
| configuration files. |
| |
| - Deprecate the sunaudio module for removal in Python 3.0. |
| |
| - Issue #3394: zipfile.writestr sets external attributes when passed a |
| file name rather than a ZipInfo instance, so files are extracted with |
| mode 0600 rather than 000 under Unix. |
| |
| - Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword |
| argument in python 2.5, this broke code that subclassed Popen to include its |
| own poll method. Fixed my moving _deadstate to an _internal_poll method. |
| |
| Build |
| ----- |
| |
| - Generate the PatternGrammar pickle during "make install". |
| |
| Documentation |
| ------------- |
| |
| - Issue #2235: the C API function PyObject_HashNotImplemented and its |
| interaction with the tp_hash slot (added in 2.6b2) are now documented |
| |
| - Issue #643841: The language reference now provides more detailed |
| coverage of the lookup process for special methods. The disclaimers |
| regarding lack of coverage of new-style classes have also been |
| removed, since the coverage is now fairly reasonable. |
| |
| |
| What's New in Python 2.6 beta 2? |
| ================================ |
| |
| *Release date: 17-Jul-2008* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #3156: Fix inconsistent behavior of the bytearray type: all |
| its methods now allow for items objects that can be converted to |
| an integer using operator.index(). |
| |
| - Issue #3360: Fix incorrect parsing of '020000000000.0', which |
| produced a ValueError instead of giving the correct float. |
| |
| - Issue #3083: Add alternate (#) formatting for bin, oct, hex output |
| for str.format(). This adds the prefix 0b, 0o, or 0x, respectively. |
| |
| - Issue #3008: the float type has a new instance method 'float.hex' |
| and a new class method 'float.fromhex' to convert floating-point |
| numbers to and from hexadecimal strings, respectively. |
| |
| - Issue #2235: __hash__ is once again inherited by default. To allow |
| collections.Hashable to remain meaningful in the presence of the |
| default hash implementation (object.__hash__), it is now possible |
| to explicit block inheritance of hash by setting __hash__=None at |
| the Python level, or tp_hash=PyObject_HashNotImplemented at the C |
| level. |
| |
| - Issue #3221: Issue a RuntimeWarning instead of raising SystemError if |
| the parent module cannot be found while performing an absolute import. |
| This means that an incorrectly defined __package__ attribute will |
| now only prevent relative imports in that module rather than causing |
| all imports from that module to fail. |
| |
| - Issue #2517: Allow unicode messages in Exceptions again by correctly |
| bypassing the instance dictionary when looking up __unicode__ on |
| new-style classes. |
| |
| - Issue #3242: Fix a crash inside the print statement, if sys.stdout is |
| set to a custom object whose write() method happens to install |
| another file in sys.stdout. |
| |
| - Issue #3088: Corrected a race condition in classes derived from |
| threading.local: the first member set by a thread could be saved in |
| another thread's dictionary. |
| |
| - Issue #3004: Minor change to slice.indices(): the start and stop |
| arguments are now treated identically, making the behaviour easier |
| to describe and understand. For example, slice(None, -10, |
| 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and |
| slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9, |
| 10, -1). |
| |
| - Issue #3219: Calling a function with repeated keyword arguments, |
| f(a=2, a=23), would not cause a syntax error. This was a regression |
| from 2.4 caused by the switch to the new compiler. |
| |
| - Issue #2862: Make int and float freelist management consistent with |
| other freelists. Changes their CompactFreeList apis into |
| ClearFreeList apis and calls them via gc.collect(). |
| |
| Library |
| ------- |
| |
| - Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python |
| api functions without holding the GIL, which could lead to a fatal |
| error when they failed. |
| |
| - Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects. |
| |
| - Issue #3395: fix reference in test_multiprocessing to old debugInfo method |
| |
| - Issue #3312: Fix two crashes in sqlite3. |
| |
| - Issue #1608818: Fix misbehavior in os.listdir() if readdir() fails. |
| |
| - Issue #3125: Remove copy_reg in multiprocessing and replace it with |
| ForkingPickler.register() to resolve conflict with ctypes. |
| |
| - Issue #3090: Fixed ARCHFLAGS parsing on OS/X |
| |
| - Issue #3313: Fixed a crash when a failed dlopen() call does not set |
| a valid dlerror() message. |
| |
| - Issue #3258: Fixed a crash when a ctypes POINTER type to an |
| incomplete structure was created. |
| |
| - Issue #3339: dummy_thread.acquire() should not return None. |
| |
| - Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments. |
| |
| - Issue #3301: Bisect module behaved badly when lo was negative. |
| |
| - Issue #839496: SimpleHTTPServer used to open text files in text mode. This is |
| both unnecessary (HTTP allows text content to be sent in several forms) and |
| wrong because the actual transmitted size could differ from the |
| content-length. The problem had been corrected in the 2.4 branch, but never |
| merged into trunk. |
| |
| - Issue #2663: add filtering capability to shutil.copytree(). |
| |
| - Issue #1622: Correct interpretation of various ZIP header fields. |
| |
| - Issue #1526: Allow more than 64k files to be added to Zip64 file. |
| |
| - Issue #1746: Correct handling of zipfile archive comments (previously |
| archives with comments over 4k were flagged as invalid). Allow writing |
| Zip files with archives by setting the 'comment' attribute of a ZipFile. |
| |
| - Issue #449227: The rlcompleter module now adds "(" to callable objects |
| when completed. |
| |
| - Issue #3190: Pydoc now hides the automatic module attribute __package__ (the |
| handling is now the same as that of other special attributes like __name__). |
| |
| - Issue #2885 (partial): The urllib.urlopen() function has been deprecated for |
| removal in Python 3.0 in favor of urllib2.urlopen(). |
| |
| - Issue #2113: Fix error in subprocess.Popen if the select system call is |
| interrupted by a signal. |
| |
| - Issue #3309: Fix bz2.BZFile iterator to release its internal lock |
| properly when raising an exception due to the bz2file being closed. |
| Prevents a deadlock. |
| |
| - Issue #3094: httplib.HTTPSConnection Host: headers no longer include the |
| redundant ":443" port number designation when the connection is using the |
| default https port (443). |
| |
| - Issue #874900: after an os.fork() call the threading module state is cleaned |
| up in the child process to prevent deadlock and report proper thread counts |
| if the new process uses the threading module. |
| |
| Tests |
| ----- |
| |
| - test.test_support.catch_warning now keeps track of all warnings it sees |
| and is now better documented. Explicit unit tests for this context manager |
| have been added to test_warnings. |
| |
| Build |
| ----- |
| |
| - Issue #3215: Build sqlite3 as sqlite3.dll, not sqlite3.pyd. |
| |
| |
| Documentation |
| ------------- |
| |
| - Document that robotparser has been renamed to urllib.robotparser in |
| Python 3.0. |
| |
| - Document that urlparse has been renamed to urllib.parse in Python 3.0. |
| |
| - Document that urllib2 is split across multiple modules and renamed in |

| |
| What's New in Python 2.6 beta 1? |
| ================================ |
| |
| *Release date: 18-June-2008* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #3211: warnings.warn_explicit() did not guard against its 'registry' |
| argument being anything other than a dict or None. Also fixed a bug in error |
| handling when 'message' and 'category' were both set to None, triggering a |
| bus error. |
| |
| - Issue #3100: Corrected a crash on deallocation of a subclassed weakref which |
| holds the last (strong) reference to its referent. |
| |
| - Add future_builtins.ascii(). |
| |
| - Several set methods now accept multiple arguments: update(), union(), |
| intersection(), intersection_update(), difference(), and difference_update(). |
| |
| - Issue #2898: Added sys.getsizeof() to retrieve size of objects in bytes. |
| |
| - New environment variable PYTHONIOENCODING. |
| |
| - Patch #2488: Add sys.maxsize. |
| |
| - Issue #2353: file.xreadlines() now emits a Py3k warning. |
| |
| - Issue #2863: generators now have a ``gen.__name__`` attribute that |
| equals ``gen.gi_code.co_name``, like ``func.__name___`` that equals |
| ``func.func_code.co_name``. The repr() of a generator now also |
| contains this name. |
| |
| - Issue #2831: enumerate() now has a ``start`` argument. |
| |
| - Issue #2801: fix bug in the float.is_integer method where a |
| ValueError was sometimes incorrectly raised. |
| |
| - Issue #2790: sys.flags was not properly exposing its bytes_warning |
| attribute. |
| |
| - Issue #2196: hasattr() now lets exceptions which do not inherit |
| Exception (KeyboardInterrupt, and SystemExit) propagate instead of |
| ignoring them. |
| |
| - Added checks for integer overflows, contributed by Google. Some are |
| only available if asserts are left in the code, in cases where they |
| can't be triggered from Python code. |
| |
| |
| Extension Modules |
| ----------------- |
| - Issue #1179: [CVE-2007-4965] Integer overflow in imageop module. |
| |
| - Issue #3116: marshal.dumps() had quadratic behavior for strings > 32Mb. |
| |
| - Issue #2138: Add factorial() to the math module. |
| |
| - The heapq module does comparisons using LT instead of LE. This |
| makes its implementation match that used by list.sort(). |
| |
| - Issue #2819: add full-precision summation function to math module, |
| based on Hettinger's ASPN Python Cookbook recipe. |
| |
| - Issue #2592: delegate nb_index and the floor/truediv slots in |
| weakref.proxy. |
| |
| - Support os.O_ASYNC and fcntl.FASYNC if the constants exist on the |
| platform. |
| |
| - Support for Windows 9x has been removed from the winsound module. |
| |
| - bsddb module updated to version 4.7.3. |
| http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.7.3. This |
| code should be compatible with Python 3.0. |
| |
| - Issue #2858: Fix potential memory corruption when |
| bsddb.db.DBEnv.lock_get and other bsddb.db object constructors |
| raised an exception. |
| |
| - Issue #2669: bsddb/__init__.py iteration no longer silently fails when |
| the database has changed size during iteration. It now raises a |
| RuntimeError in the same manner as a dictionary. |
| |
| - Issue #2870: cmathmodule.c compile error. |
| |
| - Added a threading.Thread.ident property. |
| |

| |
| - Add ``PyType_Modified()`` as a public API to clear the type cache. |
| |
| - The PyBytes functions have been renamed to PyByteArray. |
| |
| - The PyString functions have been renamed to PyBytes. A batch of |
| defines were added so that the linker still sees the original |
| PyString names. |
| |
| |
| What's New in Python 2.6 alpha 3? |
| ================================= |
| |
| *Release date: 08-May-2008* |
| |
| Core and builtins |
| ----------------- |
| |
| - Issue #2719: backported the ``next()`` builtin from Python 3. |
| |
| - Issue #2681: The octal literal ``0o8`` was incorrecly acctepted. Now |
| it properly raises a SyntaxError. |
| |
| - Issue #2617: Reserved -J and -X arguments for Jython, IronPython and |
| other implementations of Python. |
| |
| - Implemented PEP 370: Per user site-packages directory. |
| |
| Extension Modules |
| ----------------- |
| |
| - Issue #2670: Fix a failure in urllib2.build_opener(), when passed |
| two handlers that derive the same default base class. |
| |
| - Added kill, terminate and send_signal(sig) to subprocess.Popen. |
| |
| - Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to |
| the cmath module. |
| |
| - Four new methods were added to the math and cmath modules: acosh, |
| asinh, atanh and log1p. |
| |
| - zlib.decompressobj().flush(value) no longer crashes the interpreter |
| when passed a value less than or equal to zero. |
| |
| - Issue #1631171: Re-implement the 'warnings' module in C (the |
| original Python code has been kept as backup). This will allow for |
| using the 'warning's machinery in such places as the parser where |
| use of pure Python code is not possible. Both the ``showarning()`` |
| and ``formatwarning()`` gain an optional 'line' argument which is |
| not called by default for backwards-compatibility reasons. Setting |
| ``warnings.showwarning()`` to an implementation that lacks support |
| for the ``line`` argument will raise a DeprecationWarning. |
| |
| Library |
| ------- |
| |
| - The audiodev module has been deprecated for removal in Python 3.0. |
| |
| - Issue #2750: Add the 'json' package. Based on simplejson 1.9 and |
| contributed by Bob Ippolito. |
| |
| - Issue #1734346: Support Unicode file names for zipfiles. |
| |
| - Issue #2581: distutils: Vista UAC/elevation support for |
| bdist_wininst. |
| |
| - Issue #2635: Fix bug in 'fix_sentence_endings' textwrap.fill option, |
| where an extra space was added after a word containing (but not |
| ending in) '.', '!' or '?'. |
| |
| - Add from_buffer() and from_buffer_copy() class methods to ctypes |
| data types. |
| |
| - Issue #2682: ctypes callback functions no longer contain a cyclic |
| reference to themselves. |
| |
| - The getpass module has been improved on Unix. It now uses /dev/tty |
| by default and uses stderr instead of stdout. A GetPassWarning is |
| issued when input echo cannot be controlled. |
| |
| - Issue #2014: Allow XML-RPC datetime objects to have dates before |
| 1900-01-01. |
| |
| - Issue #2439: Added new function pkgutil.get_data(), which is a |
| convenience wrapper for the PEP 302 get_data() API. |
| |
| - Issue #2616: The ctypes.pointer() and ctypes.POINTER() functions are |
| now implemented in C for better performance. |
| |
| - Issue #2408: The ``_types`` module, which was used as in |
| implementation detail of the public ``types`` module, has been |
| removed and replaced by pure python code. |
| |
| - Issue #2513: distutils on Windows is now capable of cross-compiling |
| extension modules between 32 and 64 bit platforms. See the distutls |
| build documentation for more information. |
| |
| - Issue #815646: Individual file objects may now be used from multiple |
| threads at once without fear of crashing the Python interpreter. If |
| file.close() is called while an object is in use by another thread |
| an IOError exception will be raised and the file will not be closed. |
| |
| - The bundled libffi copy is now in sync with the recently released |
| libffi3.0.5 version, apart from some small changes to |
| Modules/_ctypes/libffi/configure.ac. |
| |
| - Issue #2385: distutils.core.run_script() makes __file__ available, |
| so the controlled environment will more closely mirror the typical |
| script environment. This supports setup.py scripts that refer to |
| data files. |
| |
| Tests |
| ----- |
| |
| - Issue #2550: The approach used by client/server code for obtaining |
| ports to listen on in network-oriented tests has been refined in an |
| effort to facilitate running multiple instances of the entire |
| regression test suite in parallel without issue. |
| test_support.bind_port() has been fixed such that it will always |
| return a unique port -- which wasn't always the case with the |
| previous implementation, especially if socket options had been set |
| that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The |
| new implementation of bind_port() will actually raise an exception |
| if it is passed an AF_INET/SOCK_STREAM socket with either the |
| SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if |
| available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on |
| the socket it's been passed. This currently only applies to |
| Windows. This option prevents any other sockets from binding to the |
| host/port we've bound to, thus removing the possibility of the |
| 'non-deterministic' behaviour, as Microsoft puts it, that occurs |
| when a second SOCK_STREAM socket binds and accepts to a host/port |
| that's already been bound by another socket. The optional preferred |
| port parameter to bind_port() has been removed. Under no |
| circumstances should tests be hard coding ports! |
| |
| test_support.find_unused_port() has also been introduced, which will |
| pass a temporary socket object to bind_port() in order to obtain an |
| unused port. The temporary socket object is then closed and |
| deleted, and the port is returned. This method should only be used |
| for obtaining an unused port in order to pass to an external program |
| (i.e. the -accept [port] argument to openssl's s_server mode) or as |
| a parameter to a server-oriented class that doesn't give you direct |
| access to the underlying socket used. |
| |
| Finally, test_support.HOST has been introduced, which should be used |
| for the host argument of any relevant socket calls (i.e. bind and |
| connect). |
| |
| The following tests were updated to following the new conventions: |
| test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib, |
| test_poplib, test_ftplib, test_telnetlib, test_socketserver, |
| test_asynchat and test_socket_ssl. |
| |
| It is now possible for multiple instances of the regression test |
| suite to run in parallel without issue. |
| |
| Build |
| ----- |
| |
| - Issue #1496032: On alpha, use -mieee when gcc is the compiler. |
| |
| - Issue #2544: On HP-UX systems, use 'gcc -shared' for linking when |
| gcc is used as compiler. |
| |
| - Issue #2573: On MacOS X it is now possible to install the framework |
| with a different name using --with-framework-name=NAME. |
| |
| C API |
| ----- |
| |
| - Added implementation of copysign, acosh, asinh, atanh and log1p to |
| the new files Include/pymath.h and Python/pymath.h for platforms |
| which provide the functions through their libm. The files also |
| contains several helpers and constants for math. |
| |
| - Added a new convenience macro, PyErr_WarnPy3k, for issuing Py3k warnings. |
| |
| |
| What's New in Python 2.6 alpha 2? |

| cannot be executed. |
| |
| - The compilation of a class nested in another class used to leak one |
| reference on the outer class name. |
| |

| - Issue #2355: add Py3k warning for buffer(). |
| |
| - Issue #1477: With narrow Unicode builds, the unicode escape sequence |
| \Uxxxxxxxx did not accept values outside the Basic Multilingual |
| Plane. This affected raw unicode literals and the |
| 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in |
| this case, like normal unicode literals and the 'unicode-escape' |
| codec. |

| |
| - Issue #2321: use pymalloc for unicode object string data to reduce |
| memory usage in some circumstances. |
| |
| - PEP 3127: octal literals now start with "0o". Old-style octal |
| literals are still valid. There are binary literals with a prefix of |
| "0b". This also affects int(x, 0). |
| |
| - Issue #2359: Adding deprecation warnings for array.{read,write}. |
| |
| - Issue #1779871: GNU gcc can now build Python on OS X because the |

| from 't' to '?'. |
| |
| - The bundled libffi copy is now in sync with the recently released |
| libffi3.0.4 version, apart from some small changes to |
| Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi |
| files are used. On all linux systems the --with-system-ffi |
| configure option defaults to "yes". |
| |
| - Issue #1577: shutil.move() now calls os.rename() if the destination |
| is a directory instead of copying-then-remove-source. |

| What's New in Python 2.6 alpha 1? |
| ================================= |
| |
| *Release date: 29-Feb-2008* |
| |
| Core and builtins |
| ----------------- |
| |
| - Issue #2051: pyc and pyo files are no longer created with permission |
| 644. The mode is now inherited from the py file. |
| |
| - Issue #2067: file.__exit__() now calls subclasses' close() method. |
| |
| - Patch #1759: Backport of PEP 3129 class decorators. |
| |
| - Issue #1881: An internal parser limit has been increased. Also see |
| issue #215555 for a discussion. |
| |
| - Added the future_builtins module, which contains hex() and oct(). |
| These are the PEP 3127 version of these functions, designed to be |
| compatible with the hex() and oct() builtins from Python 3.0. They |
| differ slightly in their output formats from the existing, unchanged |
| Python 2.6 builtins. The expected usage of the future_builtins |
| module is: |
| from future_builtins import hex, oct |
| |
| - Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit |
| exponents for exponents with absolute value < 100. Follows C99 |
| standard. This is a change on Windows, which would use 3 digits. |
| Also, added 'n' to the formats that PyOS_ascii_formatd understands, |
| so that any alterations it does to the resulting string will be |
| available in stringlib/formatter.h (for float.__format__). |
| |
| - Implemented PEP 3101, Advanced String Formatting. This adds a new |
| builtin format(); a format() method for str and unicode; a |
| __format__() method to object, str, unicode, int, long, float, and |
| datetime; the class string.Formatter; and the C API |
| PyObject_Format(). |
| |
| - Fixed several potential crashes, all caused by specially crafted |
| __del__ methods exploiting objects in temporarily inconsistent |
| state. |
| |
| - Issue #2115: Important speedup in setting __slot__ attributes. Also |
| prevent a possible crash: an Abstract Base Class would try to access |
| a slot on a registered virtual subclass. |
| |
| - Fixed repr() and str() of complex numbers with infinity or nan as |
| real or imaginary part. |
| |
| - Clear all free lists during a gc.collect() of the highest generation |
| in order to allow pymalloc to free more arenas. Python may give back |
| memory to the OS earlier. |
| |
| - Issue #2045: Fix an infinite recursion triggered when printing a |
| subclass of collections.defaultdict, if its default_factory is set |
| to a bound method. |
| |
| - Fixed a minor memory leak in dictobject.c. The content of the free |
| list was not freed on interpreter shutdown. |
| |
| - Limit free list of method and built-in function objects to 256 |
| entries each. |
| |
| - Patch #1953: Added ``sys._compact_freelists()`` and the C API |
| functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList`` |
| to compact the internal free lists of pre-allocted ints and floats. |
| |
| - Issue #1983: Fixed return type of fork(), fork1() and forkpty() |
| calls. Python expected the return type int but the fork familie |
| returns pi_t. |
| |
| - Issue #1678380: Fix a bug that identifies 0j and -0j when they |
| appear in the same code unit. |
| |
| - Issue #2025: Add tuple.count() and tuple.index() methods to comply |
| with the collections.Sequence API. |
| |
| - Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and |
| linebreak detection |
| |
| - Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear |
| the internal lookup cache for ref leak tests. |
| |
| - Patch #1473257: generator objects gain a gi_code attribute. This is |
| the same object as the func_code attribute of the function that |
| produced the generator. |
| |
| - Issue #1920: "while 0" statements were completely removed by the |
| compiler, even in the presence of an "else" clause, which is |
| supposed to be run when the condition is false. Now the compiler |
| correctly emits bytecode for the "else" suite. |
| |
| - A few crashers fixed: weakref_in_del.py (issue #1377858); |
| loosing_dict_ref.py (issue #1303614, test67.py); |
| borrowed_ref_[34].py (not in tracker). |
| |
| - Issue #1069410: The "can't load dll" message box on Windows is |
| suppressed while an extension is loaded by calling SetErrorMode in |
| dynload_win.c. The error is still reported properly. |
| |
| - Issue #1915: Python compiles with --enable-unicode=no again. However |
| several extension methods and modules do not work without unicode |
| support. |
| |
| - Issue #1882: when compiling code from a string, encoding cookies in the |
| second line of code were not always recognized correctly. |
| |
| - Issue #1679: "0x" was taken as a valid integer literal. |
| |
| - Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were |
| added. |
| |
| - sys.float_info / PyFloat_GetInfo: The floating point information |
| object was converted from a dict to a specialized structseq object. |
| |
| - Patch #1816: Added sys.flags structseq. It exposes the status of |
| most command line arguments and PYTHON* environment variables. |
| |
| - Objects/structseq.c: Implemented new structseq representation. The |
| patch makes structseqs (e.g. the return value of os.stat) more |
| readable. |
| |
| - Patch #1700288: added a type attribute cache that caches method |
| accesses, resulting in speedups in heavily object-oriented code. |
| |
| - Bug #1776: __import__() no longer accepts filenames on any platform. |
| The first parameter to __import__() must be a valid module name. |
| |
| - Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG. |
| |
| - Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE |
| envvar and sys.dont_write_bytecode attribute. All these can be set |
| to forbid Python to attempt to write compiled bytecode files. |
| |
| - Improve some exception messages when Windows fails to load an |
| extension module. Now we get for example '%1 is not a valid Win32 |
| application' instead of 'error code 193'. |
| |
| - Bug #1481296: Fixed long(float('nan')) != 0L. |
| |
| - Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, |
| y) functions. |
| |
| - Issue #1635: Platform independent creation and representation of NaN |
| and INF. float("nan"), float("inf") and float("-inf") now work on |
| every platform with IEEE 754 semantics. |
| |
| - Compiler now generates simpler and faster code for dictionary |
| literals. The oparg for BUILD_MAP now indicates an estimated |
| dictionary size. There is a new opcode, STORE_MAP, for adding |
| entries to the dictionary. |
| |
| - Issue #1638: %zd configure test fails on Linux. |
| |
| - Issue #1620: New property decorator syntax was modifying the |
| decorator in place instead of creating a new decorator object. |
| |
| - Issue #1538: Avoid copying string in split/rsplit if the split char |
| is not found. |
| |
| - Issue #1553: An erroneous __length_hint__ can make list() raise a |
| SystemError. |
| |
| - PEP 366: Allow explicit relative imports when executing modules |
| inside packages with the -m switch via a new module level |
| __package__ attribute. |
| |
| - Issue #1402: Fix a crash on exit, when another thread is still |
| running, and if the deallocation of its frames somehow calls the |
| PyGILState_Ensure() / PyGILState_Release() functions. |
| |
| - Expose the Py_Py3kWarningFlag as sys.py3kwarning. |
| |
| - Issue #1445: Fix a SystemError when accessing the ``cell_contents`` |
| attribute of an empty cell object. |
| |
| - Issue #1460: The utf-7 incremental decoder did not accept truncated |
| input. It now correctly saves its state between chunks of data. |
| |
| - Patch #1739468: Directories and zipfiles containing a __main__.py |
| file can now be directly executed by passing their name to the |
| interpreter. The directory/zipfile is automatically inserted as the |
| first entry in sys.path. |
| |
| - Issue #1265: Fix a problem with sys.settrace, if the tracing |
| function uses a generator expression when at the same time the |
| executed code is closing a paused generator. |
| |
| - sets and frozensets now have an isdisjoint() method. |
| |
| - optimize the performance of builtin.sum(). |
| |
| - Fix warnings found by the new version of the Coverity checker. |
| |
| - The enumerate() built-in function is no longer bounded to sequences |
| smaller than LONG_MAX. Formerly, it raised an OverflowError. Now, |
| automatically shifts from ints to longs. |
| |
| - Issue #1686386: Tuple's tp_repr did not take into account the |
| possibility of having a self-referential tuple, which is possible |
| from C code. Nor did object's tp_str consider that a type's tp_str |
| could do something that could lead to an inifinite recursion. |
| Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the |
| issues. |
| |
| - Issue #1164: It was possible to trigger deadlock when using the |
| 'print' statement to write to a file since the GIL was not released |
| as needed. Now PyObject_Print() does the right thing along with |
| various tp_print implementations of the built-in types and those in |
| the collections module. |
| |
| - Issue #1147: Exceptions were directly allowing string exceptions in |
| their throw() method even though string exceptions no longer |
| allowed. |
| |
| - Issue #1096: Prevent a segfault from getting the repr of a very |
| deeply nested list by using the recursion counter. |
| |
| - Issue #1202533: Fix infinite recursion calls triggered by calls to |
| PyObject_Call() never calling back out to Python code to trigger |
| recursion depth updates/checks. Required the creation of a static |
| RuntimeError instance in case normalizing an exception put the |
| recursion check value past its limit. Fixes crashers |
| infinite_rec_(1|2|4|5).py. |
| |
| - Patch #1031213: Decode source line in SyntaxErrors back to its |
| original source encoding. |
| |
| - Patch #1673759: add a missing overflow check when formatting floats |
| with %G. |
| |
| - Prevent expandtabs() on string and unicode objects from causing a |
| segfault when a large width is passed on 32-bit platforms. |
| |
| - Issue #1733488: Fix compilation of bufferobject.c on AIX. |
| |
| - Issue #1722485: remove docstrings again when running with -OO. |
| |
| - Add new attribute names for function objects. All the func_* become |
| __*__ attributes. (Some already existed, e.g., __doc__ and |
| __name__.) |
| |
| - Add -3 option to the interpreter to warn about features that are |
| deprecated and will be changed/removed in Python 3.0. |
| |
| - Patch #1686487: you can now pass any mapping after '**' in function |
| calls. |
| |
| - except clauses may now be spelled either "except E, target:" or |
| "except E as target:". This is to provide forwards compatibility |
| with Python 3.0. |
| |
| - Deprecate BaseException.message as per PEP 352. |
| |
| - Issue #1303614: don't expose object's __dict__ when the dict is |
| inherited from a built-in base. |
| |
| - When __slots__ are set to a unicode string, make it work the same as |
| setting a plain string, ie don't expand to single letter identifiers. |
| |
| - Request #1191699: Slices can now be pickled. |
| |
| - Request #1193128: str.translate() now allows a None argument for |
| translations that only remove characters without re-mapping the |
| remaining characters. |
| |
| - Patch #1682205: a TypeError while unpacking an iterable is no longer |
| masked by a generic one with the message "unpack non-sequence". |
| |
| - Remove unused file Python/fmod.c. |
| |
| - Bug #1683368: The object.__init__() and object.__new__() methods are |
| now stricter in rejecting excess arguments. The only time when |
| either allows excess arguments is when it is not overridden and the |
| other one is. For backwards compatibility, when both are |
| overridden, it is a deprecation warning (for now; maybe a Py3k |
| warning later). Also, type.__init__() insists on the same signature |
| as supported by type.__new__(). |
| |
| - Patch #1675423: PyComplex_AsCComplex() now tries to convert an |
| object to complex using its __complex__() method before falling back |
| to the __float__() method. Therefore, the functions in the cmath |
| module now can operate on objects that define a __complex__() |
| method. |
| |
| - Patch #1623563: allow __class__ assignment for classes with |
| __slots__. The old and the new class are still required to have the |
| same slot names. |
| |
| - Patch #1642547: Fix an error/crash when encountering syntax errors |
| in complex if statements. |
| |
| - Patch #1462488: Python no longer segfaults when |
| ``object.__reduce_ex__()`` is called with an object that is faking |
| its type. |
| |
| - Patch #1680015: Don't modify __slots__ tuple if it contains an |
| unicode name. |
| |
| - Patch #1444529: the builtin compile() now accepts keyword arguments. |
| |
| - Bug #1678647: write a newline after printing an exception in any |
| case, even when converting the value to a string failed. |
| |
| - The dir() function has been extended to call the __dir__() method on |
| its argument, if it exists. If not, it will work like before. This |
| allows customizing the output of dir() in the presence of a |
| __getattr__(). |
| |
| - Patch #922167: Python no longer segfaults when faced with infinitely |
| self-recursive reload() calls (as reported by bug #742342). |
| |
| - Patch #1675981: remove unreachable code from ``type.__new__()`` |
| method. |
| |
| - Patch #1491866: change the complex() constructor to allow |
| parthensized forms. This means complex(repr(x)) now works instead of |
| raising a ValueError. |
| |
| - Patch #703779: unset __file__ in __main__ after running a file. This |
| makes the filenames the warning module prints much more sensible |
| when a PYTHONSTARTUP file is used. |
| |
| - Variant of patch #697613: don't exit the interpreter on a SystemExit |
| exception if the -i command line option or PYTHONINSPECT environment |
| variable is given, but break into the interactive interpreter just |
| like on other exceptions or normal program exit. |
| |
| - Patch #1638879: don't accept strings with embedded NUL bytes in |
| long(). |
| |
| - Bug #1674503: close the file opened by execfile() in an error |
| condition. |
| |
| - Patch #1674228: when assigning a slice (old-style), check for the |
| sq_ass_slice instead of the sq_slice slot. |
| |
| - When printing an unraisable error, don't print exceptions. before |
| the name. This duplicates the behavior whening normally printing |
| exceptions. |
| |
| - Bug #1653736: Properly discard third argument to |
| slot_nb_inplace_power. |
| |
| - PEP 352: Raising a string exception now triggers a TypeError. |
| Attempting to catch a string exception raises DeprecationWarning. |
| |
| - Bug #1377858: Fix the segfaulting of the interpreter when an object |
| created a weakref on itself during a __del__ call for new-style |
| classes (classic classes still have the bug). |
| |
| - Bug #1579370: Make PyTraceBack_Here use the current thread, not the |
| frame's thread state. |
| |
| - patch #1630975: Fix crash when replacing sys.stdout in |
| sitecustomize.py. |
| |
| - Prevent seg fault on shutdown which could occur if an object raised |
| a warning. |
| |
| - Bug #1566280: Explicitly invoke threading._shutdown from Py_Main, to |
| avoid relying on atexit. |
| |
| - Bug #1590891: random.randrange don't return correct value for big |
| number. |
| |
| - Patch #1586791: Better exception messages for some operations on |
| strings, tuples and lists. |
| |
| - Bug #1067760: Deprecate passing floats to file.seek. |
| |
| - Bug #1591996: Correctly forward exception in instance_contains(). |
| |
| - Bug #1588287: fix invalid assertion for `1,2` in debug builds. |
| |
| - Bug #1576657: when setting a KeyError for a tuple key, make sure |
| that the tuple isn't used as the "exception arguments tuple". |
| |
| - Bug #1565514: SystemError not raised on too many nested blocks. |
| |
| - Bug #1576174: WindowsError now displays the windows error code |
| again, no longer the posix error code. |
| |
| - Patch #1549049: Support long values in structmember, issue warnings |
| if the assigned value for structmember fields gets truncated. |
| |
| - Update the peephole optimizer to remove more dead code (jumps after |
| returns) and inline unconditional jumps to returns. |
| |
| - Bug #1545497: when given an explicit base, int() did ignore NULs |
| embedded in the string to convert. |
| |
| - Bug #1569998: break inside a try statement (outside a loop) is now |
| recognized and rejected. |
| |
| - list.pop(x) accepts any object x following the __index__ protocol. |
| |
| - A number of places, including integer negation and absolute value, |
| were fixed to not rely on undefined behaviour of the C compiler |
| anymore. |
| |
| - Bug #1566800: make sure that EnvironmentError can be called with any |
| number of arguments, as was the case in Python 2.4. |
| |
| - Patch #1567691: super() and new.instancemethod() now don't accept |
| keyword arguments any more (previously they accepted them, but |
| didn't use them). |
| |
| - Fix a bug in the parser's future statement handling that led to |
| "with" not being recognized as a keyword after, e.g., this |
| statement: from __future__ import division, with_statement |
| |
| - Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)). |
| |
| - Fix %zd string formatting on Mac OS X so it prints negative numbers. |
| |
| - Allow exception instances to be directly sliced again. |
| |
| - Bug #1551432: Exceptions do not define an explicit __unicode__ |
| method. This allows calling unicode() on exceptions classes |
| directly to succeed. |
| |
| - Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack. |
| Also make sure that every exception class has __module__ set to |
| 'exceptions'. |
| |
| - Bug #1550983: emit better error messages for erroneous relative |
| imports (if not in package and if beyond toplevel package). |
| |
| - Overflow checking code in integer division ran afoul of new gcc |
| optimizations. Changed to be more standard-conforming. |
| |
| - Patch #1542451: disallow continue anywhere under a finally. |
| |
| - Patch #1546288: fix seg fault in dict_equal due to ref counting bug. |
| |
| - The return tuple from str.rpartition(sep) is (tail, sep, head) where |
| head is the original string if sep was not found. |
| |
| - Bug #1520864: unpacking singleton tuples in list comprehensions and |
| generator expressions (x for x, in ... ) works again. Fixing this |
| problem required changing the .pyc magic number. This means that |
| .pyc files generated before 2.5c2 will be regenerated. |
| |
| - ``with`` and ``as`` are now keywords. |
| |
| - Bug #1664966: Fix crash in exec if Unicode filename can't be |
| decoded. |
| |
| - Issue #1537: Changed GeneratorExit's base class from Exception to |
| BaseException. |
| |
| - Issue #1703448: A joined thread could show up in the |
| threading.enumerate() list after the join() for a brief period until |
| it actually exited. |
| |

| default permissions for missing directories. |
| |
| - Issue #175006: The debugger used to skip the condition of a "while" |
| statement after the first iteration. Now it correctly steps on the |
| expression, and breakpoints on the "while" statement are honored on |
| each loop. |
| |
| - Issue #1765140: add an optional delay argument to FileHandler and |
| its subclasses. Defaults to false (existing behaviour), but if true, |
| defers opening the file until the first call to emit(). |
| |

| (as opposed to the command line) will now write file names ending in |
| ".cpp" too. |
| |
| - As specified in RFC 2616, an HTTP response like 2xx indicates that |

| closes patch #723312. |
| |
| - Patch #1676823: Added create_connection() to socket.py, which may be |

| directories. |
| |
| - Bug #1681228: the webbrowser module now correctly uses the default |
| GNOME or KDE browser, depending on whether there is a session of one |

| pydoc.doc() does. |
| |
| - Patch #1533909: the timeit module now accepts callables in addition |
| to strings for the code to time and the setup code. Also added two |
| convenience functions for instantiating a Timer and calling its |
| methods. |
| |
| - Patch #1537850: tempfile.NamedTemporaryFile now has a "delete" |
| parameter which can be set to False to prevent the default |
| delete-on-close behavior. |
| |
| - Patch #1581073: add a flag to textwrap that prevents the dropping of |
| whitespace while wrapping. |
| |
| - Patch #1603688: ConfigParser.SafeConfigParser now checks values that |
| are set for invalid interpolation sequences that would lead to |
| errors on reading back those values. |

| names now has a descriptive message. |
| |
| - Bug #1115886: os.path.splitext('.cshrc') gives now ('.cshrc', ''). |
| |
| - unittest now verifies more of its assumptions. In particular, |
| TestCase and TestSuite subclasses (not instances) are no longer |
| accepted in TestSuite.addTest(). This should cause no |
| incompatibility since it never made sense with ordinary subclasses |
| -- the failure just occurred later, with a more cumbersome |
| exception. |
| |
| - Patch #787789: allow to pass custom TestRunner instances to |
| unittest's main() function. |
| |
| - Patches #1550273, #1550272: fix a few bugs in unittest and add a |

| with statement compiled by the compiler package crashed the |
| interpreter. |
| |
| - Bug #1643943: Fix time.strptime's support for the %U directive. |
| |
| - Patch #1507247: tarfile.py: use current umask for intermediate |
| directories. |

| |
| - Bug #494589: make ntpath.expandvars behave according to its |
| docstring. |

| python_implementation() and linux_distribution(). |
| |
| - Added support for IronPython and Jython to the platform module. |

| works as expected. ``mmap.find`` also takes an optional ``end`` |
| parameter. |
| |
| - _winreg's HKEY object has gained __enter__ and __exit__ methods to |
| support the context manager protocol. The _winreg module also |
| gained a new function ``ExpandEnvironmentStrings`` to expand |

| - pybsddb.sf.net Bug #477182: Load the database flags at database open |
| time so that opening a database previously created with the DB_DUP |
| or DB_DUPSORT flag set will keep the proper behavior on subsequent |
| opens. Specifically: dictionary assignment to a DB object will |
| replace all values for a given key when the database allows |
| duplicate values. DB users should use DB.put(k, v) when they want |
| to store duplicates; not DB[k] = v. |

| |
| - Bug #1686475: Support stat'ing open files on Windows again. |
| |
| - Patch #1185447: binascii.b2a_qp() now correctly quotes binary |

| fails. |
| |
| - Speed up function calls into the math module. |
| |
| - Bug #1588217: don't parse "= " as a soft line break in binascii's |

| codepoints now. |
| |
| - Bug #1552726: in readline.c, avoid repeatedly polling in interactive |
| mode by only placing a timeout on the select() if an input hook has |
| been defined. This prevents an interactive Python from waking up 10 |
| times per second. Patch by Richard Boulton. |
| |

| were transposed. |
| |
| - Added support for linking the bsddb module against BerkeleyDB 4.5.x, |
| 4.6.x and 4.7.x. |

| |
| - Refactor test_profile and test_cprofile to use the same code to |
| profile. |
| |
| - Make test_runpy reentrant by fixing _check_module to clear out any |
| module being tested. Was causing an error by __import__ doing a |
| reload on the second run and thus suppressing bytecode recreation. |
| |

| test_urllib2net and raise test.test_support.ResourceDenied. |
| |
| - Patch #1559413: Fix test_cmd_line if sys.executable contains a |
| space. |

| if test.test_support.requires says that the resource should exist. |
| |
| - Added a test for slicing of an exception. |
| |

| |
| Tools |
| ----- |
| |
| - Tools/scripts/reindent.py now creates the backup file using |
| shutil.copy to preserve user/group and permissions. Added also a |
| --nobackup option to not create the backup if the user is concerned |
| regarding this. Check issue #1050828 for more details. |
| |
| - Tools/scripts/win_add2path.py was added. The simple script modifes |
| the PATH environment var of the HKCU tree and adds the python bin |
| and script directory. |

| - Patch #1540470: for OpenBSD 4.0. |
| |
| - Fix build failure on kfreebsd and on the hurd. |
| |
| - Fix the build of the library reference in info format. |
| |
| - Allow Emacs 22 for building the documentation in info format. |
| |
| - Makefile.pre.in(buildbottest): Run an optional script |
| pybuildbot.identify to include some information about the build |
| environment. |
| |
| |
| C API |
| ----- |
| |
| - Unified naming convention for free lists and their limits. All free |
| lists in Object/ are named ``free_list``, the counter ``numfree`` |
| and the upper limit is a macro ``PyName_MAXFREELIST`` inside an |
| #ifndef block. |
| |
| - ``PySet_Add()`` can now modify a newly created frozenset. Similarly |
| to ``PyTuple_SetItem``, it can be used to populate a brand new |
| frozenset; but it does not steal a reference to the added item. |
| |
| - Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API. |
| |
| - Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format |
| and _FormatV from Python 3.0. Made PyLong_AsSsize_t and |
| PyLong_FromSsize_t public functions. |
| |
| - Patch #1720595: add T_BOOL to the range of structmember types. |
| |
| - Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and |
| ``PyFloat_GetInfo()`` to the float API. |
| |
| - Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# |
| of w# format code incorrectly truncated the length to an int, even |
| when PY_SSIZE_T_CLEAN is set. The str.decode method used to return |
| incorrect results with huge strings. |
| |
| - Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, |
| Py_TYPE and Py_REFCNT. |
| |
| - PEP 3123: Provide forward compatibility with Python 3.0, while |
| keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, |
| and PyVarObject_HEAD_INIT. |
| |
| - Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not |
| defined. |
| |
| - Patch #1733960: Allow T_LONGLONG to accept ints. |
| |
| - T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members. |
| |
| - Added a new API function ``PyImport_ImportModuleNoBlock``. |
| |
| - Bug #1637022: Prefix AST symbols with _Py_. |
| |
| - Fix some leftovers from the conversion from int to Py_ssize_t |
| (relevant to strings and sequences of more than 2**31 items). |
| |
| - Make _PyGILState_NoteThreadState() static, it was not used anywhere |
| outside of pystate.c and should not be necessary. |
| |
| - ``PyImport_Import`` and ``PyImport_ImportModule`` now always do |
| absolute imports. In earlier versions they might have used relative |
| imports under some conditions. |
| |
| - Added case insensitive comparison methods ``PyOS_stricmp(char*, |
| char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``. |
| |
| - Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx |
| macro so it can be used as an expression. |
| |
| |
| Windows |
| ------- |
| |
| - Patch #1706: Drop support for Win9x, WinME and NT4. Python now |
| requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION |
| macros are set to Win2k for x86/32bit builds and WinXP for AMD64 |
| builds. |
| |
| - Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and |
| _CRT_NONSTDC_NO_DEPRECATE. |
| |
| - Bug #1216: Restore support for Visual Studio 2002. |
| |
| |
| Mac |
| --- |
| |
| - cfmfile now raises a DeprecationWarning. |
| |
| - buildtools now raises a DeprecationWarning. |
| |
| - Removed the macfs module. It had been deprecated since Python 2.5. |
| This lead to the deprecation of macostools.touched() as it relied |
| solely on macfs and was a no-op under OS X. |
