| IDLE |
| ---- |
| |
| - Issue #15348: Stop the debugger engine (normally in a user process) |
| before closing the debugger window (running in the IDLE process). |
| This prevents the RuntimeErrors that were being caught and ignored. |
| |
| - Issue #24455: Prevent IDLE from hanging when a) closing the shell while the |
| debugger is active (15347); b) closing the debugger with the [X] button |
| (15348); and c) activating the debugger when already active (24455). |
| The patch by Mark Roseman does this by making two changes. |
| 1. Suspend and resume the gui.interaction method with the tcl vwait |
| mechanism intended for this purpose (instead of root.mainloop & .quit). |
| 2. In gui.run, allow any existing interaction to terminate first. |

| about the other buttons and the new IDLE Dark theme. |
| |
| - Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme. |
| It is more or less IDLE Classic inverted, with a cobalt blue background. |
| Strings, comments, keywords, ... are still green, red, orange, ... . |
| To use it with IDLEs released before November 2015, hit the |
| 'Save as New Custom Theme' button and enter a new name, |
| such as 'Custom Dark'. The custom theme will work with any IDLE |
| release, and can be modified. |
| |
| - Issue #25224: README.txt is now an idlelib index for IDLE developers and |
| curious users. The previous user content is now in the IDLE doc chapter. |

| |
| - Issue #24199: Deprecate unused idlelib.idlever with possible removal in 3.6. |

| Extension Modules |
| ----------------- |
| |
| - Issue #17477: Update the bsddb module to pybsddb 5.3.0, supporting |
| db-5.x, and dropping support for db-4.1 and db-4.2. |

| - Issue #17192: Update the ctypes module's libffi to v3.0.13. This |
| specifically addresses a stack misalignment issue on x86 and issues on |
| some more recent platforms. |
| |
| - Issue #12268: The io module file object write methods no longer abort early |
| when a write system calls is interrupted (EINTR). |
| |
| - Fix the leak of a dict in the time module when used in an embedded |
| interpreter that is repeatedly initialized and shutdown and reinitialized. |
| |
| - Issue #12268: File readline, readlines and read or readall methods |
| no longer lose data when an underlying read system call is interrupted |
| within an io module object. IOError is no longer raised due to a read |
| system call returning EINTR from within these methods. |

| In particular, fix extension module build failures when trying to use |
| 32-bit-only installer Pythons on systems with Xcode 4 (currently |
| OS X 10.8, 10.7, and optionally 10.6). |
| * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4) |
| * Since Xcode 4 removes ppc support, extension module builds now |
| check for ppc compiler support and by default remove ppc and |
| ppc64 archs when they are not available. |
| * Extension module builds now revert to using system installed |
| headers and libs (/usr and /System/Library) if the SDK used |
| to build the interpreter is not installed or has moved. |
| * Try to avoid building extension modules with deprecated |
| and problematic Apple llvm-gcc compiler. If original compiler |
| is not available, use clang instead by default. |

| - Issue #13020: Fix a reference leak when allocating a structsequence object |
| fails. Patch by Suman Saha. |
| |
| - Issue #13703: oCERT-2011-003: add -R command-line option and PYTHONHASHSEED |
| environment variable, to provide an opt-in way to protect against denial of |
| service attacks due to hash collisions within the dict and set types. Patch |
| by David Malcolm, based on work by Victor Stinner. |
| |
| - Issue #11235: Fix OverflowError when trying to import a source file whose |
| modification time doesn't fit in a 32-bit timestamp. |
| |
| - Issue #11638: Unicode strings in 'name' and 'version' no longer cause |
| UnicodeDecodeErrors. |
| |
| - Fix the fix for issue #12149: it was incorrect, although it had the side |
| effect of appearing to resolve the issue. Thanks to Mark Shannon for |
| noticing. |
| |
| - Issue #13546: Fixed an overflow issue that could crash the intepreter when |
| calling sys.setrecursionlimit((1<<31)-1). |
| |
| - Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder |
| already accepts them). |
| |
| - Issue #10519: Avoid unnecessary recursive function calls in |
| setobject.c. |
| |
| - Issue #13268: Fix the assert statement when a tuple is passed as the message. |

| - Issue #7732: Fix a crash on importing a module if a directory has the same |
| name than a Python module (e.g. "__init__.py"): don't close the file twice. |
| |
| - Issue #12973: Fix overflow checks that invoked undefined behaviour in |
| int.__pow__. These overflow checks were causing int.__pow__ to produce |
| incorrect results with recent versions of Clang, as a result of the |
| compiler optimizing the check away. Also fix similar overflow checks |
| in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These |
| bugs caused test failures with recent versions of Clang. |

| deallocator calls one of the methods on the type (e.g. when subclassing |
| IOBase). Diagnosis and patch by Davide Rizzo. |
| |

| again in Python 3.2. |

| - Issue #1326113: distutils' build_ext command --libraries option now |
| correctly parses multiple values separated by whitespace or commas. |
| |
| - Issue #13993: HTMLParser is now able to handle broken end tags. |
| |
| - Issue #13960: HTMLParser is now able to handle broken comments. |
| |
| - Issue #9750: Fix sqlite3.Connection.iterdump on tables and fields |
| with a name that is a keyword or contains quotes. Patch by Marko |
| Kohtala. |
| |
| - Issue #13994: Earlier partial revert of Distutils enhancements in 2.7 |
| has left two versions of customize_compiler, the original in |
| distutils.sysconfig and another copy in distutils.ccompiler, with some |
| parts of distutils calling one and others using the other. |
| Complete the revert back to only having one in distutils.sysconfig as |
| is the case in 3.x. |
| |
| - Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building |
| Distutils-based packages with C extension modules may fail because |
| Apple has removed gcc-4.2, the version used to build python.org |
| 64-bit/32-bit Pythons. If the user does not explicitly override |
| the default C compiler by setting the CC environment variable, |
| Distutils will now attempt to compile extension modules with clang |
| if gcc-4.2 is required but not found. Also as a convenience, if |
| the user does explicitly set CC, substitute its value as the default |
| compiler in the Distutils LDSHARED configuration variable for OS X. |
| (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u |
| SDK, neither of which are available in Xcode 4. This change does not |
| attempt to override settings to support their use with Xcode 4.) |
| |
| - Issue #9021: Add an introduction to the copy module documentation. |
| |
| - Issue #6005: Examples in the socket library documentation use sendall, where |
| relevant, instead send method. |

| raise a ProgrammingError now. |
| |
| - Issue #13676: Handle strings with embedded zeros correctly in sqlite3. |

| - Issue #6631: Disallow relative file paths in urllib urlopen methods. |
| |
| - Issue #13781: Prevent gzip.GzipFile from using the dummy filename provided by |

| - tarfile.py: Correctly detect bzip2 compressed streams with blocksizes |
| other than 900k. |
| |
| - Issue #13573: The csv.writer now uses the repr() for floats rather than str(). |
| This allows floats to round-trip without loss of precision. |
| |
| - Issue #13439: Fix many errors in turtle docstrings. |
| |
| - Issue #12856: Ensure child processes do not inherit the parent's random |
| seed for filename generation in the tempfile module. Patch by Brian |
| Harring. |

| certificate with a subjectAltName. Patch by Robert Xiao. |
| |

| |
| - Issue #13322: Fix BufferedWriter.write() to ensure that BlockingIOError is |
| raised when the wrapped raw file is non-blocking and the write would block. |

| |
| - Issue #1548891: The cStringIO.StringIO() constructor now encodes unicode |
| arguments with the system default encoding just like the write() method |
| does, instead of converting it to a raw buffer. This also fixes handling of |
| unicode input in the shlex module (#6988, #1170). |
| |
| - Issue #9168: now smtpd is able to bind privileged port. |
| |
| - Issue #12529: fix cgi.parse_header issue on strings with double-quotes and |
| semicolons together. Patch by Ben Darnell and Petri Lehtinen. |

| of crashing when an invalid path is given in the manifest template. |
| |
| - Issue #12841: tarfile unnecessarily checked the existence of numerical user |

| of the current user (i.e. root) was used for the file and ownership |
| information was lost. |
| |

| |
| - Issue #12352: Fix a deadlock in multiprocessing.Heap when a block is freed by |
| the garbage collector while the Heap lock is held. |
| |
| - Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to |
| check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the |
| interpreter process. This could cause failures in non-Distutils subprocesses |
| and was unreliable since tests or user programs could modify the interpreter |
| environment after Distutils set it. Instead, have Distutils set the |
| deployment target only in the environment of each build subprocess. It is |
| still possible to globally override the default by setting |
| MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be |
| greater or equal to the default value, the value with which the interpreter |
| was built. |
| |

| connection if its getresponse() method fails with a socket error. Patch |
| written by Ezio Melotti. |

| functions. |
| |

| instead of os.stat. |
| |
| - Issue #12080: Fix a performance issue in Decimal._power_exact that caused |
| some corner-case Decimal.__pow__ calls to take an unreasonably long time. |
| |
| - Named tuples now work correctly with vars(). |
| |
| - sys.setcheckinterval() now updates the current ticker count as well as |
| updating the check interval, so if the user decreases the check interval, |
| the ticker doesn't have to wind down to zero from the old starting point |
| before the new interval takes effect. And if the user increases the |
| interval, it makes sure the new limit takes effect right away rather have an |
| early task switch before recognizing the new interval. |
| |
| - Issue #12085: Fix an attribute error in subprocess.Popen destructor if the |
| constructor has failed, e.g. because of an undeclared keyword argument. Patch |
| written by Oleg Oshmyan. |
| |

| |
| - Issue #9869: Make long() and PyNumber_Long return something of type |
| long for a class whose __long__ method returns a plain int. This |
| fixes an interpreter crash when initializing an instance of a long |
| subclass from an object whose __long__ method returns a plain int. |
| |
| - Issue #10006: type.__abstractmethods__ now raises an AttributeError. |
| |
| - Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid |
| thread-local storage key. |
| |
| - Issue #4947: The write() method of sys.stdout and sys.stderr uses their |
| encoding and errors attributes instead of using utf-8 in strict mode, to get |
| the same behaviour than the print statement. |
| |
| - Issue #9737: Fix a crash when trying to delete a slice or an item from |
| a memoryview object. |
| |
| - Restore GIL in nis_cat in case of error. |

| ZipFile.open()) could return more bytes than requested. |
| |
| - Issue #9825: removed __del__ from the definition of collections.OrderedDict. |
| This prevents user-created self-referencing ordered dictionaries from |
| becoming permanently uncollectable GC garbage. The downside is that |
| removing __del__ means that the internal doubly-linked list has to wait for |
| GC collection rather than freeing memory immediately when the refcnt drops |
| to zero. |
| |

| avoid issues when socket.close is called from a __del__ method. |
| |
| - Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which |
| can be set to False to turn off the previously undocumented 'popularity' |
| heuristic. Patch by Terry Reedy and Eli Bendersky |
| |
| - Issue #8797: urllib2 does a retry for Basic Authentication failure instead of |
| falling into recursion. |
| |
| - Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four |
| character years even if the message contains RFC822 two character years. |
| |
| - Issue #8750: Fixed MutableSet's methods to correctly handle |
| reflexive operations, namely x -= x and x ^= x. |
| |

| error handling when accepting a new connection. |

| ignored by the buffered IO layer anymore. |
| |
| - Issue #2521: Use weakrefs on for caching in the abc module, so that classes |
| are not held onto after they are deleted elsewhere. |
| |
| - Issue #9626: the view methods for collections.OrderedDict() were returning |
| the unordered versions inherited from dict. Those methods are now |
| overridden to provide ordered views. |
| |
| - Issue #8688: MANIFEST files created by distutils now include a magic |
| comment indicating they are generated. Manually maintained MANIFESTs |
| without this marker will not be overwritten or removed. |
| |
| - Issue #7467: when reading a file from a ZIP archive, its CRC is checked |
| and a BadZipfile error is raised if it doesn't match (as used to be the |
| case in Python 2.5 and earlier). |
| |
| - Issue #9550: a BufferedReader could issue an additional read when the |
| original read request had been satisfied, which could block indefinitely |
| when the underlying raw IO channel was e.g. a socket. Report and original |
| patch by Jason V. Miller. |
| |
| - Issue #9551: Don't raise TypeError when setting the value to None for |
| SafeConfigParser instances constructed with allow_no_value == True. |

| current node. |
| |
| - Issue #6869: Fix a refcount problem in the _ctypes extension. |
| |
| - Issue #5504: ctypes should now work with systems where mmap can't be |
| PROT_WRITE and PROT_EXEC. |
| |
| - Issue #8280: urllib2's Request method will remove fragements in the url. |
| This is how it is supposed to work, wget and curl do the same. Previous |
| behavior was wrong. |
| |
| - Issue #2944: asyncore doesn't handle connection refused correctly. |
| |
| - Issue #3196: email header decoding is now forgiving if an RFC2047 |
| encoded word encoded in base64 is lacking padding. |
| |
| - Issue #9444: Argparse now uses the first element of prefix_chars as |
| the option character for the added 'h/help' option if prefix_chars |
| does not contain a '-', instead of raising an error. |
| |

| power of 10 and the exponent is tiny (for example, |
| Decimal(10) ** Decimal('1e-999999999')). |

| What's New in Python 2.7 Release Candidate 1? |
| ============================================= |
| |
| *Release date: 2010-06-05* |
| |
| Core and Builtins |
| ----------------- |
| |
| - 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 #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 #8748: Fix two issues with comparisons between complex and integer |
| objects. (1) The comparison could incorrectly return True in some cases |
| (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality. |
| (2) The comparison raised an OverflowError for large integers, leading |
| to unpredictable exceptions when combining integers and complex objects |
| in sets or dicts. |
| |
| - Issue #5211: Implicit coercion for the complex type is now completely |
| removed. (Coercion for arithmetic operations was already removed in 2.7 |
| alpha 4, but coercion for rich comparisons was accidentally left in.) |
| |
| - 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 #8868: Fix that ensures that python scripts have access to the |
| Window Server again in a framework build on MacOSX 10.5 or earlier. |
| |
| 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 |
| ------- |
| |
| - Issue #8302: SkipTest in unittest.TestCase.setUpClass or setUpModule is now |
| reported as a skip rather than an error. |
| |
| - Issue #8351: Excessively large diffs due to |
| unittest.TestCase.assertSequenceEqual are no longer included in failure |
| reports. |
| |
| - Issue #8899: time.struct_time now has class and attribute docstrings. |
| |
| - Issue #4487: email now accepts as charset aliases all codec aliases |
| accepted by the codecs module. |
| |
| - Issue #6470: Drop UNC prefix in FixTk. |
| |
| - Issue #5610: feedparser no longer eats extra characters at the end of |
| a body part if the body part ends with a \r\n. |
| |
| - Issue #8833: tarfile created hard link entries with a size field != 0 by |
| mistake. |
| |
| - Issue #1368247: set_charset (and therefore MIMEText) now automatically |
| encodes a unicode _payload to the output_charset. |
| |
| - Issue #7150: Raise OverflowError if the result of adding or subtracting |
| timedelta from date or datetime falls outside of the MINYEAR:MAXYEAR range. |
| |
| - Issue #6662: Fix parsing of malformatted charref (&#bad;), patch written by |
| Fredrik Håård |
| |
| - Issue #8016: Add the CP858 codec. |
| |
| - Issue #3924: Ignore cookies with invalid "version" field in cookielib. |
| |
| - Issue #6268: Fix seek() method of codecs.open(), don't read or write the BOM |
| twice after seek(0). Fix also reset() method of codecs, UTF-16, UTF-32 and |
| StreamWriter classes. |
| |
| - Issue #5640: Fix Shift-JIS incremental encoder for error handlers different |
| than 'strict'. |
| |
| - Issue #8782: Add a trailing newline in linecache.updatecache to the last line |
| of files without one. |
| |
| - Issue #8729: Return NotImplemented from ``collections.Mapping.__eq__()`` when |
| comparing to a non-mapping. |
| |
| - Issue #8759: Fix user paths in sysconfig for posix and os2 schemes. |
| |
| - Issue #1285086: Speed up ``urllib.quote()`` and urllib.unquote for simple |
| cases. |
| |
| - Issue #8688: Distutils now recalculates MANIFEST every time. |
| |
| - Issue #5099: The ``__del__()`` method of ``subprocess.Popen`` (and the methods |
| it calls) referenced global objects, causing errors to pop up during |
| interpreter shutdown. |
| |
| Extension Modules |
| ----------------- |
| |
| - Issue #7384: If the system readline library is linked against ncurses, |
| the curses module must be linked against ncurses as well. Otherwise it |
| is not safe to load both the readline and curses modules in an application. |
| |
| - Issue #2810: Fix cases where the Windows registry API returns |
| ERROR_MORE_DATA, requiring a re-try in order to get the complete result. |
| |
| - Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing |
| overflow checks in the ``audioop`` module. |
| |

| |
| - Issue #8889: test_support.transient_internet rewritten so that the new |
| checks also work on FreeBSD, which lacks EAI_NODATA. |
| |
| - Issue #8835: test_support.transient_internet() catches gaierror(EAI_NONAME) |
| and gaierror(EAI_NODATA) |
| |
| - Issue #7449: Skip test_socketserver if threading support is disabled |
| |
| - On darwin, ``test_site`` assumed that a framework build was being used, |
| leading to a failure where four directories were expected for site-packages |
| instead of two in a non-framework build. |
| |
| Build |
| ----- |
| |
| - Display installer warning that Windows 2000 won't be supported in future |
| releases. |
| |
| - Issues #1759169, #8864: Drop _XOPEN_SOURCE on Solaris, define it for |
| multiprocessing only. |
| |
| Tools/Demos |
| ----------- |
| |
| - Issue #5464: Implement plural forms in msgfmt.py. |
| |
| |
| What's New in Python 2.7 beta 2? |
| ================================ |
| |
| *Release date: 2010-05-08* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Run Clang 2.7's static analyzer for ``Objects/`` and ``Python/``. |
| |
| - 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 #8202: ``sys.argv[0]`` is now set to '-m' instead of '-c' when searching |
| for the module file to be executed with the -m command line option. |
| |
| - Issue #7319: When -Q is used, do not silence DeprecationWarning. |
| |
| - Issue #7332: Remove the 16KB stack-based buffer in |
| ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable |
| benefit compared to the dynamic memory allocation fallback. Patch by |
| Charles-François Natali. |
| |
| - Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is |
| passed to bytearray. |
| |
| - Issue #7072: ``isspace(0xa0)`` is true on Mac OS X. |
| |
| - Issue #8404: Fix set operations on dictionary views. |
| |
| - Issue #8084: PEP 370 now conforms to system conventions for framework builds |
| on MacOS X. That is, ``python setup.py install --user`` will install into |
| ``~/Library/Python/2.7`` instead of ``~/.local``. |
| |
| Library |
| ------- |
| |
| - Issue #8681: Make the zlib module's error messages more informative when the |
| zlib itself doesn't give any detailed explanation. |
| |
| - Issue #8571: Fix an internal error when compressing or decompressing a chunk |
| larger than 1GB with the zlib module's compressor and decompressor objects. |
| |
| - Issue #8573: asyncore ``_strerror()`` function might throw ValueError. |
| |
| - Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error |
| messages when accessing undefined class attributes because of the cheap |
| inheritance with the underlying socket object. The cheap inheritance has been |
| deprecated. |
| |
| - Issue #4265: ``shutil.copyfile()`` was leaking file descriptors when disk |
| fills. Patch by Tres Seaver. |
| |
| - Issue #7755: Use an unencumbered audio file for tests. |
| |
| - Issue #8621: ``uuid.uuid4()`` returned the same sequence of values in the |
| parent and any children created using ``os.fork`` on Mac OS X 10.6. |
| |
| - Issue #8313: ``traceback.format_exception_only()`` encodes unicode message to |
| ASCII with backslashreplace error handler if ``str(value)`` failed. |
| |
| - Issue #8567: Fix precedence of signals in Decimal module: when a Decimal |
| operation raises multiple signals and more than one of those signals is |
| trapped, the specification determines the order in which the signals should be |
| handled. In many cases this order wasn't being followed, leading to the wrong |
| Python exception being raised. |
| |
| - Issue #7865: The close() method of :mod:`io` objects should not swallow |
| exceptions raised by the implicit flush(). Also ensure that calling close() |
| several times is supported. Patch by Pascal Chambon. |
| |
| - Issue #8576: logging updated to remove usage of find_unused_port(). |
| |
| - Issue #4687: Fix accuracy of garbage collection runtimes displayed with |
| gc.DEBUG_STATS. |
| |
| - Issue #8354: The siginterrupt setting is now preserved for all signals, not |
| just SIGCHLD. |
| |
| - Issue #7192: ``webbrowser.get("firefox")`` now works on Mac OS X, as does |
| ``webbrowser.get("safari")``. |
| |
| - Issue #8577: ``distutils.sysconfig.get_python_inc()`` now makes a difference |
| between the build dir and the source dir when looking for "python.h" or |
| "Include". |
| |
| - Issue #8464: tarfile no longer creates files with execute permissions set when |
| mode="w|" is used. |
| |
| - Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions of |
| the Linux kernel. Patch by Yaniv Aknin. |
| |
| - Issue #6312: Fix http HEAD request when the transfer encoding is chunked. It |
| should correctly return an empty response now. |
| |
| - Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test |
| suites, the ``IGNORE_EXCEPTION_DETAIL`` directive now also ignores the module |
| location of the raised exception. Based on initial patch by Lennart Regebro. |
| |
| - Issue #8086: In :func:`ssl.DER_cert_to_PEM_cert()`, fix missing newline before |
| the certificate footer. Patch by Kyle VanderBeek. |
| |
| - Issue #8546: Reject None given as the buffering argument to ``_pyio.open()``. |
| |
| - Issue #8549: Fix compiling the _ssl extension under AIX. Patch by Sridhar |
| Ratnakumar. |
| |
| - Issue #6656: Fix locale.format_string to handle escaped percents and mappings. |
| |
| - Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where |
| the method could block indefinitely if called just before the event loop |
| started running. This also fixes the occasional freezes witnessed in |
| test_httpservers. |
| |
| - Issue #5103: SSL handshake would ignore the socket timeout and block |
| indefinitely if the other end didn't respond. |
| |
| - The do_handshake() method of SSL objects now adjusts the blocking mode of the |
| SSL structure if necessary (as other methods already do). |
| |
| - Issue #7507: Quote "!" in pipes.quote(); it is special to some shells. |
| |
| - Issue #5238: Calling makefile() on an SSL object would prevent the underlying |
| socket from being closed until all objects get truely destroyed. |
| |
| - Issue #7943: Fix circular reference created when instantiating an SSL socket. |
| Initial patch by Péter Szabó. |
| |
| - Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the |
| string "python" as the *ident*. openlog() arguments are all optional and |
| keywords. |
| |
| - Issue #8108: Fix the unwrap() method of SSL objects when the socket has a |
| non-infinite timeout. Also make that method friendlier with applications |
| wanting to continue using the socket in clear-text mode, by disabling |
| OpenSSL's internal readahead. Thanks to Darryl Miles for guidance. |
| |
| - Issue #8484: Load all ciphers and digest algorithms when initializing the _ssl |
| extension, such that verification of some SSL certificates doesn't fail |
| because of an "unknown algorithm". |
| |
| - Issue #8437: Fix test_gdb failures, patch written by Dave Malcolm |
| |
| - Issue #4814: The timeout parameter is now applied also for connections |
| resulting from PORT/EPRT commands. |
| |
| - Issue #8463: Add missing reference to bztar in shutil's documentation. |
| |
| - Issue #8438: Remove reference to the missing "surrogateescape" encoding error |
| handler from the new IO library. |
| |
| - Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response code |
| as stated in RFC-959 at chapter 5.4. |
| |
| - Issue #8279: Fix test_gdb failures. |
| |
| - Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the |
| available cipher list. Helps fix test_ssl with OpenSSL 1.0.0. |
| |
| - Issue #2987: RFC 2732 support for urlparse (IPv6 addresses). Patch by Tony |
| Locke and Hans Ulrich Niedermann. |
| |
| - Issue #7585: difflib context and unified diffs now place a tab between |
| filename and date, conforming to the 'standards' they were originally designed |
| to follow. This improves compatibility with patch tools. |
| |
| - Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022 |
| character sets will now consistently use a Content-Transfer-Encoding of 7bit |
| rather than sometimes being marked as 8bit. |
| |
| - Issue #8330: Fix expected output in test_gdb. |
| |
| - Issue #8374: Update the internal alias table in the :mod:`locale` module to |
| cover recent locale changes and additions. |
| |
| Extension Modules |
| ----------------- |
| |
| - Issue #8644: Improved accuracy of ``timedelta.total_seconds()``. |
| |
| - Use Clang 2.7's static analyzer to find places to clean up some code. |
| |
| - Build the ossaudio extension on GNU/kFreeBSD. |
| |
| - On Windows, ctypes no longer checks the stack before and after calling a |
| foreign function. This allows using the unmodified libffi library. |
| |
| Tests |
| ----- |
| |
| - 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 #8490: asyncore now has a more solid test suite which actually tests its |
| API. |
| |
| - Issue #8576: Remove use of find_unused_port() in test_smtplib and |
| test_multiprocessing. Patch by Paul Moore. |
| |
| - Issue #7449: Fix many tests to support Python compiled without thread support. |
| Patches written by Jerry Seutter. |
| |
| - Issue #8108: test_ftplib's non-blocking SSL server now has proper handling of |
| SSL shutdowns. |
| |
| Build |
| ----- |
| |
| - Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc. |
| (Optimization was unintentionally turned on in gcc --with-pydebug builds in |
| 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's |
| strange choice of default CFLAGS produced by AC_PROG_CC for gcc.) |
| |
| - Issue #8509: Fix quoting in help strings and code snippets in configure.in. |
| |
| - Issue #3646: It is now easily possible to install a Python framework into your |
| home directory on Mac OS X, see Mac/README for more information. |
| |
| - Issue #8510: Update to autoconf 2.65. |
| |
| Misc |
| ---- |
| |
| - Update the Vim syntax highlight file. |
| |
| |
| What's New in Python 2.7 beta 1? |
| ================================ |
| |
| *Release date: 2010-04-10* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #7301: Add environment variable $PYTHONWARNINGS. |
| |
| - Issue #8329: Don't return the same lists from select.select when no fds are |
| changed. |
| |
| - Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error' |
| on 64-bit machines. The shift count for either left or right shift is |
| permitted to be up to sys.maxsize. |
| |
| - Ensure that tokenization of identifiers is not affected by locale. |
| |
| - Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever. |
| |
| - Raise a TypeError when trying to delete a T_STRING_INPLACE struct member. |
| |
| - Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called |
| with a non-empty format string. This is an effort to future-proof user |
| code. If a derived class does not currently implement __format__ but later |
| adds its own __format__, it would most likely break user code that had |
| supplied a format string. This will be changed to a DeprecationWarning in |
| Python 3.3 and it will be an error in Python 3.4. |
| |
| - Issue #8268: Old-style classes (not just instances) now support weak |
| references. |
| |
| - Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it |
| is set. |
| |
| - Issue #1583863: A unicode subclass can now override the __unicode__ method |
| |
| - Issue #6474: Make error message from passing an inadequate number of keyword |
| arguments to a function correct. |
| |
| - Issue #8164: Don't allow lambda functions to have a docstring. |
| |
| - Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt |
| (SIGINT). If an error occurs while importing the site module, the error is |
| printed and Python exits. Initialize the GIL before importing the site |
| module. |
| |
| - Code objects now support weak references. |
| |
| Library |
| ------- |
| |
| - Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters. |
| |
| - Issue #8321: Give access to OpenSSL version numbers from the `ssl` module, |
| using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and |
| `ssl.OPENSSL_VERSION_NUMBER`. |
| |
| - Issue #8310: Allow dis to examine new style classes. |
| |
| - Issue #8257: The Decimal construct now accepts a float instance directly, |
| converting that float to a Decimal of equal value: |
| |
| >>> Decimal(1.1) |
| Decimal('1.100000000000000088817841970012523233890533447265625') |
| |
| - collections.Counter() now supports a subtract() method. |
| |
| - The functools module now has a total_ordering() class decorator to simplify |
| the specification of rich comparisons. |
| |
| - The functools module also adds cmp_to_key() as a tool to transition old-style |
| comparison functions to new-style key-functions. |
| |
| - Issue #8294: The Fraction constructor now accepts Decimal and float instances |
| directly. |
| |
| - Issue #7279: Comparisons involving a Decimal signaling NaN now signal |
| InvalidOperation instead of returning False. (Comparisons involving a quiet |
| NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal |
| signaling NaNs remain unhashable. |
| |
| - Issue #2531: Comparison operations between floats and Decimal instances now |
| return a result based on the numeric values of the operands; previously they |
| returned an arbitrary result based on the relative ordering of id(float) and |
| id(Decimal). |
| |
| - Issue #8233: When run as a script, py_compile.py optionally takes a single |
| argument `-` which tells it to read files to compile from stdin. Each line is |
| read on demand and the named file is compiled immediately. (Original patch by |
| Piotr Ożarowski). |
| |
| - Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a |
| function like a normal call. |
| |
| - Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and |
| form feed (0x0C) are now considered linebreaks, as specified in Unicode |
| Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/ |
| |
| - Comparisons using one of <, <=, >, >= between a complex instance and a |
| Fractions instance now raise TypeError instead of returning True/False. This |
| makes Fraction <=> complex comparisons consistent with int <=> complex, float |
| <=> complex, and complex <=> complex comparisons. |
| |
| - Addition of ``WeakSet`` to the ``weakref`` module. |
| |
| - logging: Added LOG_FTP to SysLogHandler and updated documentation. |
| |
| - Issue #8205: Remove the "Modules" directory from sys.path when Python is |
| running from the build directory (POSIX only). |
| |
| - Issue #7667: Fix doctest failures with non-ASCII paths. |
| |
| - Issue #7512: shutil.copystat() could raise an OSError when the filesystem |
| didn't support chflags() (for example ZFS under FreeBSD). The error is now |
| silenced. |
| |
| - Issue #7703: ctypes supports both buffer() and memoryview(). The former is |
| deprecated. |
| |
| - Issue #7860: platform.uname now reports the correct 'machine' type when Python |
| is running in WOW64 mode on 64 bit Windows. |
| |
| - logging: Added getChild utility method to Logger and added isEnabledFor method |
| to LoggerAdapter. |
| |
| - Issue #8201: logging: Handle situation of non-ASCII and Unicode logger names |
| existing at the same time, causing a Unicode error when configuration code |
| attempted to sort the existing loggers. |
| |
| - Issue #8200: logging: Handle errors when multiprocessing is not fully loaded |
| when logging occurs. |
| |
| - Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets. |
| Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking |
| reads and writes are always retried by OpenSSL itself. |
| |
| - Issue #8179: Fix macpath.realpath() on a non-existing path. |
| |
| - Issue #8024: Update the Unicode database to 5.2. |
| |
| - Issue #8104: socket.recv_into() and socket.recvfrom_into() now support writing |
| into objects supporting the new buffer API, for example bytearrays or |
| memoryviews. |
| |
| - Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox |
| with Tcl/Tk-8.5. |
| |
| - Issue #8140: Extend compileall to compile single files. Add -i option. |
| |
| - Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set |
| to an non existent program name and Python is unable to retrieve the real |
| program name. |
| |
| - Issue #8117: logging: Improved algorithm for computing initial rollover time |
| for ``TimedRotatingFileHandler`` by using the modification time of an existing |
| log file to compute the next rollover time. If the log file does not exist, |
| the current time is used as the basis for the computation. |
| |
| - Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The |
| cElementTree module is updated too. |
| |
| - Issue #7880: Fix sysconfig when the python executable is a symbolic link. |
| |
| - Issue #7624: Fix ``isinstance(foo(), collections.Callable)`` for old-style |
| classes. |
| |
| - Issue #7143: email: ``get_payload()`` used to strip any trailing newline from |
| a base64 transfer-encoded payload *after* decoding it; it no longer does. |
| This is a behavior change, so email's minor version number is now bumped, to |
| version 4.0.2, for the 2.7 release. |
| |
| - Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is |
| a socket option available on FreeBSD 7.1 and newer. |
| |
| - Issue #8038: unittest.TestCase.assertNotRegexpMatches |
| |
| - Addition of -b command line option to unittest for buffering stdout / stderr |
| during test runs. |
| |
| - Issue #1220212: Added os.kill support for Windows, including support for |
| sending CTRL+C and CTRL+BREAK events to console subprocesses. |
| |
| Extension Modules |
| ----------------- |
| |
| - Issue #8314: Fix unsigned long long bug in libffi on Sparc v8. |
| |
| - Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument. |
| |
| - Issue #8156: bsddb module updated to version 4.8.4. |
| http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4. This update drops |
| support for Berkeley DB 4.0, and adds support for 4.8. |
| |
| - Issue #3928: os.mknod() now available in Solaris, also. |
| |
| - Issue #8142: Update libffi to the 3.0.9 release. |
| |
| - Issue #8300: When passing a non-integer argument to struct.pack with any |
| integer format code, struct.pack first attempts to convert the non-integer |
| using its __index__ method. If that method is non-existent or raises |
| TypeError it goes on to try the __int__ method, as described below. |
| |
| - Issue #1530559: When passing a non-integer argument to struct.pack with *any* |
| integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the |
| argument's __int__ method to convert to an integer before packing. It also |
| produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was |
| inconsistent: __int__ was used for some integer codes but not for others, and |
| the set of integer codes for which it was used differed between native packing |
| and standard packing.) |
| |
| - Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a bug in |
| the return value of QueryReflectionKey. |
| |
| Tools/Demos |
| ----------- |
| |
| - Issue #7993: Add a test of IO packet processing bandwidth to ccbench. It |
| measures the number of UDP packets processed per second depending on the |
| number of background CPU-bound Python threads. |
| |
| - python-config now supports multiple options on the same command line. |
| |
| Build |
| ----- |
| |
| - Issue #8032: For gdb7, a python-gdb.py file is added to the build, allowing to |
| use advanced gdb features when debugging Python. |
| |
| - Issue #1628484: The Makefile doesn't ignore the CFLAGS environment variable |
| anymore. It also forwards the LDFLAGS settings to the linker when building a |
| shared library. |
| |
| - Issue #6716: Quote -x arguments of compileall in MSI installer. |
| |
| - Issue #7705: Fix linking on FreeBSD. |
| |
| - Make sure that the FreeBSD build of the included libffi uses the proper |
| assembly file. |
| |
| C-API |
| ----- |
| |
| - Issue #8276: PyEval_CallObject() is now only available in macro form. The |
| function declaration, which was kept for backwards compatibility reasons, is |
| now removed (the macro was introduced in 1997!). |
| |
| - Issue #7992: A replacement PyCObject API, PyCapsule, has been backported from |
| Python 3.1. All existing Python CObjects in the main distribution have been |
| converted to capsules. To address backwards-compatibility concerns, |
| PyCObject_AsVoidPtr() was changed to understand capsules. |
| |
| Tests |
| ----- |
| |
| - Issue #3864: Skip three test_signal tests on freebsd6 because they fail if any |
| thread was previously started, most likely due to a platform bug. |
| |
| - Issue #8348: Fix test ftp url in test_urllib2net. |
| |
| - Issue #8204: Fix test_ttk notebook test by forcing focus. |

| |
| - Issue #7242: On Solaris 9 and earlier calling ``os.fork()`` from within a |
| thread could raise an incorrect RuntimeError about not holding the import |
| lock. The import lock is now reinitialized after fork. |

| filesystem encoding. |
| |
| - Issue #6292: For the moment at least, the test suite runs cleanly if python |
| is run with the -OO flag. Tests requiring docstrings are skipped. |
| |
| - Issue #7712: test_support gained a new ``temp_cwd`` context manager which is |
| now also used by regrtest to run all the tests in a temporary directory. The |
| original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent |
| Xicluna who helped with the patch. |
| |
| Build |
| ----- |
| |
| - Issue #3920, #7903: Define _BSD_SOURCE on OpenBSD 4.4 through 4.9. |
| |
| |
| What's New in Python 2.7 alpha 3? |
| ================================= |
| |
| *Release date: 2010-02-06* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #5677: Explicitly forbid write operations on read-only file objects, |
| and read operations on write-only file objects. On Windows, the system C |
| library would return a bogus result; on Solaris, it was possible to crash the |
| interpreter. Patch by Stefan Krah. |
| |
| - Issue #7853: Normalize exceptions before they are passed to a context |
| manager's ``__exit__()`` method. |
| |
| - Issue #7385: Fix a crash in ``PyMemoryView_FromObject()`` when |
| ``PyObject_GetBuffer()`` fails. Patch by Florent Xicluna. |
| |
| - Issue #7819: Check ``sys.call_tracing()`` arguments types. |
| |
| - Issue #7788: Fix an interpreter crash produced by deleting a list slice with |
| very large step value. |
| |
| - Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple |
| and add the additional members returned in an OSVERSIONINFOEX structure. The |
| new members are service_pack_major, service_pack_minor, suite_mask, and |
| product_type. |
| |
| - Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``) |
| could crash in many places because of the ``PyByteArray_AS_STRING()`` macro |
| returning NULL. The macro now returns a statically allocated empty string |
| instead. |
| |
| - Issue #7622: Improve the split(), rsplit(), splitlines() and replace() |
| methods of bytes, bytearray and unicode objects by using a common |
| implementation based on stringlib's fast search. Patch by Florent Xicluna. |
| |
| - Issue #7632: Fix various str -> float conversion bugs present in 2.7 alpha 2, |
| including: |
| |
| (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input |
| strings, |
| (2) a crash in dtoa.c that occurred in debug builds when parsing certain long |
| numeric strings corresponding to subnormal values, |
| (3) a memory leak for some values large enough to cause overflow, and |
| (4) a number of flaws that could lead to incorrectly rounded results. |
| |
| - Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3 |
| option is not used. |
| |
| - Issue #2335: Backport set literals syntax from Python 3.x. |
| |
| - Issue #2333: Backport set and dict comprehensions syntax from Python 3.x. |
| |
| - Issue #1967: Backport dictionary views from Python 3.x. |
| |
| Library |
| ------- |
| |
| - Issue #9137: Fix issue in MutableMapping.update, which incorrectly |
| treated keyword arguments called 'self' or 'other' specially. |
| |
| - Issue #7835: shelve should no longer produce mysterious warnings during |
| interpreter shutdown. |
| |
| - Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in |
| XML processing instructions and comments. These raw characters are allowed |
| by the XML specification, and are necessary when outputting e.g. PHP code in |
| a processing instruction. Patch by Neil Muller. |
| |
| - Issue #7869: logging: Improved diagnostic for format-time errors. |
| |
| - Issue #7868: logging: Added loggerClass attribute to Manager. |
| |
| - Issue #7851: logging: Clarification on logging configuration files. |
| |
| - Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is |
| specified, rather than fall through to AF_PACKET (in the ``socket`` module). |
| Also, raise ValueError rather than TypeError when an unknown TIPC address |
| type is specified. Patch by Brian Curtin. |
| |
| - logging: Implemented PEP 391. |
| |
| - Issue #6939: Fix file I/O objects in the `io` module to keep the original |
| file position when calling `truncate()`. It would previously change the file |
| position to the given argument, which goes against the tradition of |
| ftruncate() and other truncation APIs. Patch by Pascal Chambon. |
| |
| - Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile`` |
| class used to represent files stored inside an archive. The new |
| implementation is significantly faster and can be wrapped in an |
| ``io.BufferedReader`` object for more speedups. It also solves an issue |
| where interleaved calls to ``read()`` and ``readline()`` give wrong results. |
| Patch by Nir Aides. |
| |
| - Issue #7792: Registering non-classes to ABCs raised an obscure error. |
| |
| - Removed the deprecated functions ``verify()`` and ``vereq()`` from |
| Lib/test/test_support.py. |
| |
| - Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()`` |
| when the release file is empty. |
| |
| - Issue #7748: Since unicode values are supported for some metadata options in |
| Distutils, the DistributionMetadata get_* methods will now return a utf-8 |
| encoded string for them. This ensures that the upload and register commands |
| send the correct values to PyPI without any error. |
| |
| - Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping |
| headers in multipart/signed MIME parts, which fixes one of the sources of |
| invalid modifications to such parts by Generator. |
| |
| - Issue #7701: Fix crash in ``binascii.b2a_uu()`` in debug mode when given a |
| 1-byte argument. Patch by Victor Stinner. |
| |
| - Issue #3299: Fix possible crash in the _sre module when given bad argument |
| values in debug mode. Patch by Victor Stinner. |
| |
| - Issue #7703: Add support for the new buffer API to functions of the binascii |
| module. Backported from py3k by Florent Xicluna, with some additional tests. |
| |
| - Issue #2846: Add support for gzip.GzipFile reading zero-padded files. Patch |
| by Brian Curtin. |
| |
| - Issue #5827: Make sure that normpath preserves unicode. Initial patch by |
| Matt Giuca. |
| |
| - Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since |
| Extension extra options may change the output without changing the .c file). |
| Initial patch by Collin Winter. |
| |
| Extension Modules |
| ----------------- |
| |
| - Expat: Fix DoS via XML document with malformed UTF-8 sequences |
| (CVE_2009_3560). |
| |
| Build |
| ----- |
| |
| - Issue #7632: When Py_USING_MEMORY_DEBUGGER is defined, disable the private |
| memory allocation scheme in dtoa.c and use PyMem_Malloc and PyMem_Free |
| instead. Also disable caching of powers of 5. |
| |
| - Issue #7658: Ensure that the new pythonw executable works on OSX 10.4 |
| |
| - Issue #7714: Use ``gcc -dumpversion`` to detect the version of GCC on |
| MacOSX. |
| |
| - Issue #7661: Allow ctypes to be built from a non-ASCII directory path. |
| Patch by Florent Xicluna. |
| |
| Tools/Demos |
| ----------- |
| |
| - iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were |
| added to the ``Tools`` directory. They were previously living in the |
| sandbox. |
| |
| Tests |
| ----- |
| |
| - Issue #7728: test_timeout was changed to use ``test_support.bind_port()`` |
| instead of a hard coded port. |
| |
| Documentation |
| ------------- |
| |
| - Updated "Using Python" documentation to include description of CPython's -J, |
| -U and -X options. |
| |
| - Updated Python manual page (options -B, -O0, -s, environment variables |
| PYTHONDONTWRITEBYTECODE, PYTHONNOUSERSITE). |
| |
| |
| What's New in Python 2.7 alpha 2? |
| ================================= |
| |
| *Release date: 2010-01-09* |
| |
| Core and Builtins |
| ----------------- |
| |
| - The ``__complex__()`` method is now looked up on the class of instances to |
| make it consistent with other special methods. |
| |
| - Issue #7462: Implement the stringlib fast search algorithm for the `rfind`, |
| `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna. |
| |
| - Issue #5080: A number of functions and methods previously produced a |
| DeprecationWarning when passed a float argument where an integer was expected. |
| These functions and methods now raise TypeError instead. The majority of the |
| effects of this change are in the extension modules, but some core functions |
| and methods are affected: notably the 'chr', 'range' and 'xrange' builtins, |
| and many unicode/str methods. |
| |
| - Issue #7604: Deleting an unset slotted attribute did not raise an |
| AttributeError. |
| |
| - Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero) |
| in ** operator. The behaviour now conforms to that described in C99 Annex F. |
| |
| - Issue #7579: The msvcrt module now has docstrings for all its functions. |
| |
| - Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat() |
| used to drop the time part of the result. |
| |
| - Issue #1811: Improve accuracy and cross-platform consistency for true division |
| of integers: the result of a/b is now correctly rounded for ints a and b (at |
| least on IEEE 754 platforms), and in particular does not depend on the |
| internal representation of a long. |
| |
| - Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the |
| same message when only ``__str__()`` (and not ``__unicode__()``) is overridden |
| in the subclass. |
| |
| - Issue #6834: Replace the implementation for the 'python' and 'pythonw' |
| executables on OSX. |
| |
| These executables now work properly with the arch(1) command: ``arch -ppc |
| python`` will start a universal binary version of python in PPC mode (unlike |
| previous releases). |
| |
| - Issue #1680159: Unicode coercion during an 'in' operation no longer masks the |
| underlying error when the coercion fails for the left hand operand. |
| |
| - Issue #7491: Metaclass's __cmp__ method was ignored. |
| |
| - Issue #7466: Segmentation fault when the garbage collector is called in the |
| middle of populating a tuple. Patch by Florent Xicluna. |
| |
| Library |
| ------- |
| |
| - Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``, |
| allowing for a maximum number of tasks within the pool to be completed by the |
| worker before that worker is terminated, and a new one created to replace it. |
| |
| - Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc |
| when it has a fully qualified configuration prefix. Initial patch by |
| Arfrever. |
| |
| - Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles |
| renaming of `cPickle` to `pickle`. The warning was annoying since there's no |
| alternative to cPickle if you care about performance. Patch by Florent |
| Xicluna. |
| |
| - Issue #7455: Fix possible crash in cPickle on invalid input. Patch by Victor |
| Stinner. |
| |
| - Issue #7092: Fix the DeprecationWarnings emitted by the standard library when |
| using the -3 flag. Patch by Florent Xicluna. |
| |
| - Issue #7471: Improve the performance of GzipFile's buffering mechanism, and |
| make it implement the ``io.BufferedIOBase`` ABC to allow for further speedups |
| by wrapping it in an ``io.BufferedReader``. Patch by Nir Aides. |
| |
| - Issue #3972: ``httplib.HTTPConnection`` now accepts an optional source_address |
| parameter to allow specifying where your connections come from. |
| |
| - ``socket.create_connection()`` now accepts an optional source_address |
| parameter. |
| |
| - Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager. |
| Initial patch by Brian Curtin. |
| |
| - Distutils now correctly identifies the build architecture as "x86_64" when |
| building on OSX 10.6 without "-arch" flags. |
| |
| - Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest file in text |
| mode. |
| |
| - Issue #7552: Removed line feed in the base64 Authorization header in the |
| Distutils upload command to avoid an error when PyPI reads it. This occurs on |
| long passwords. Initial patch by JP St. Pierre. |
| |
| - Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by |
| Tatsuhiro Tsujikawa. |
| |
| - Issue #7349: Make methods of file objects in the io module accept None as an |
| argument where file-like objects (ie StringIO and BytesIO) accept them to mean |
| the same as passing no argument. |
| |
| - Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no |
| argument like other file objects. |
| |
| - Issue #7357: tarfile no longer suppresses fatal extraction errors by default. |
| |
| - Issue #7470: logging: Fix bug in Unicode encoding fallback. |
| |
| - Issue #5949: Fixed IMAP4_SSL hang when the IMAP server response is missing |
| proper end-of-line termination. |
| |
| - Issue #7457: Added a read_pkg_file method to |
| ``distutils.dist.DistributionMetadata``. |
| |
| - Issue #3745: Undo the 2.7a1 change to have hashlib to reject unicode and non |
| buffer API supporting objects as input. That behavior is for 3.x only. |
| |
| C-API |
| ----- |
| |
| - Issue #7767: New function ``PyLong_AsLongLongAndOverflow()`` added, analogous |
| to ``PyLong_AsLongAndOverflow()``. |
| |
| - Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``, |
| ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``, |
| ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept |
| float arguments for integer format codes (other than 'L'): previously an |
| attempt to pass a float resulted in a DeprecationWarning; now it gives a |
| TypeError. For the 'L' format code (which previously had no warning) there is |
| now a DeprecationWarning. |
| |
| - Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added. |
| |
| Build |
| ----- |
| |
| - Issue #6491: Allow --with-dbmliborder to specify that no dbms will be built. |
| |
| - Issue #6943: Use pkg-config to find the libffi headers when the |
| ``--with-system-ffi`` flag is used. |
| |
| - Issue #7609: Add a ``--with-system-expat`` option that causes the system's |
| expat library to be used for the pyexpat module instead of the one included |
| with Python. |
| |
| - Issue #7589: Only build the nis module when the correct header files are |
| found. |
| |
| - Switch to OpenSSL 0.9.8l and sqlite 3.6.21 on Windows. |
| |
| - Issue #7541: when using ``python-config`` with a framework install the |
| compiler might use the wrong library. |
| |
| Tests |
| ----- |
| |
| - Issue #7376: Instead of running a self-test (which was failing) when called |
| with no arguments, doctest.py now gives a usage message. |
| |
| - Issue #7396: Fix regrtest -s, which was broken by the -j enhancement. |
| |
| - Issue #7498: test_multiprocessing now uses test_support.find_unused_port |
| instead of a hardcoded port number in test_rapid_restart. |
| |
| |
| What's New in Python 2.7 alpha 1 |
| ================================ |
| |
| *Release date: 2009-12-05* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows |
| when called with invalid values. |
| |
| - Issue #3382: 'F' formatting for float and complex now convert the result to |
| upper case. This only affects 'inf' and 'nan', since 'f' no longer converts |
| to 'g' for large values. |
| |
| - Remove switch from "%f" formatting to "%g" formatting for floats larger than |
| 1e50 in absolute value. |
| |
| - Remove restrictions on precision when formatting floats. E.g., "%.120g" % |
| 1e-100 used to raise OverflowError, but now gives the requested 120 |
| significant digits instead. |
| |
| - Add Py3k warnings for parameter names in parentheses. |
| |
| - Issue #7362: Give a proper error message for ``def f((x)=3): pass``. |
| |
| - Issue #7085: Fix crash when importing some extensions in a thread on MacOSX |
| 10.6. |
| |
| - Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest |
| decimal string that's guaranteed to round back to x under correct rounding |
| (with round-half-to-even rounding mode). Previously it gave a string based on |
| rounding x to 17 decimal digits. repr(x) for a complex number behaves |
| similarly. On platforms where the correctly-rounded strtod and dtoa code is |
| not supported (see below), repr is unchanged. |
| |
| - Issue #7117: On almost all platforms: float-to-string and string-to-float |
| conversions within Python are now correctly rounded. Places these conversions |
| occur include: str for floats and complex numbers; the float and complex |
| constructors; old-style and new-style numeric formatting; serialization and |
| deserialization of floats and complex numbers using marshal, pickle and json; |
| parsing of float and imaginary literals in Python code; Decimal-to-float |
| conversion. |
| |
| The conversions use a Python-adapted version of David Gay's well-known dtoa.c, |
| providing correctly-rounded strtod and dtoa C functions. This code is |
| supported on Windows, and on Unix-like platforms using gcc, icc or suncc as |
| the C compiler. There may be a small number of platforms on which correct |
| operation of this code cannot be guaranteed, so the code is not used: notably, |
| this applies to platforms where the C double format is not IEEE 754 binary64, |
| and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision |
| and Python's configure script is unable to determine how to change the FPU |
| precision. On these platforms conversions use the platform strtod and dtoa, |
| as before. |
| |
| - Issue #7117: Backport round implementation from Python 3.x. ``round()`` now |
| uses the correctly-rounded string <-> float conversions described above (when |
| available), and so produces correctly rounded results that will display nicely |
| under the float repr. There are two related small changes: (1) round now |
| accepts any class with an ``__index__()`` method for its second argument (but |
| no longer accepts floats for the second argument), and (2) an excessively |
| large second integer argument (e.g., ``round(1.234, 10**100)``) no longer |
| raises an exception. |
| |
| - Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding. |
| |
| - Fix several issues with ``compile()``. The input can now contain Windows and |
| Mac newlines and is no longer required to end in a newline. |
| |
| - Remove length limitation when constructing a complex number from a unicode |
| string. |
| |
| - Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised |
| during the formation of an output tuple. |
| |
| - Issue #1087418: Boost performance of bitwise operations for longs. |
| |
| - Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``, |

| interpreter is killed. Patch by Adam Olsen. |
| |
| - Issue #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``, |
| and note that they are unsafe and deprecated. |
| |
| - Issue #7120: logging: Remove import of multiprocessing which is causing crash |
| in GAE. |
| |
| - Issue #7140: The ``__dict__`` of a module should not be cleared unless the |
| module is the only object holding a reference to it. |
| |
| - Issue #1754094: Improve the stack depth calculation in the compiler. There |
| should be no other effect than a small decrease in memory use. Patch by |
| Christopher Tur Lesniewski-Laas. |
| |
| - Issue #7084: Fix a (very unlikely) crash when printing a list from one thread, |
| and mutating it from another one. Patch by Scott Dial. |
| |
| - Issue #1571184: The Unicode database contains properties for more characters. |
| The tables for code points representing numeric values, white spaces or line |
| breaks are now generated from the official Unicode Character Database files, |
| and include information from the Unihan.txt file. |
| |
| - Issue #7050: Fix a SystemError when trying to use unpacking and augmented |
| assignment. |
| |
| - Issue #5329: Fix ``os.popen*`` regression from 2.5 with commands as a sequence |
| running through the shell. Patch by Jean-Paul Calderone and Jani Hakala. |
| |
| - Issue #7019: Raise ValueError when unmarshalling bad long data, instead of |
| producing internally inconsistent Python longs. |
| |
| - Issue #6990: Fix ``threading.local`` subclasses leaving old state around after |
| a reference cycle GC which could be recycled by new locals. |
| |
| - Issue #6300: unicode.encode, unicode.decode, str.decode, and str.encode now |
| take keyword arguments. |
| |
| - Issue #6922: Fix an infinite loop when trying to decode an invalid UTF-32 |
| stream with a non-raising error handler like "replace" or "ignore". |
| |

| when writing from multiple threads at the same time. |
| |
| - Issue #6704: Improve the col_offset in AST for "for" statements with a target |
| of tuple unpacking. |
| |
| - Issue #6707: ``dir()`` on an uninitialized module caused a crash. |
| |
| - Issue #6540: Fixed crash for ``bytearray.translate()`` with invalid parameters. |
| |
| - Issue #6573: ``set.union()`` stopped processing inputs if an instance of self |
| occurred in the argument chain. |
| |
| - Issue #1616979: Added the cp720 (Arabic DOS) encoding. |
| |
| - Issue #6070: On posix platforms import no longer copies the execute bit from |
| the .py file to the .pyc file if it is set. Patch by Marco N. |
| |
| - Issue #4618: When unicode arguments are passed to ``print()``, the default |
| separator and end should be unicode also. |
| |
| - Issue #6119: Fixed an incorrect Py3k warning about order comparisons of |
| built-in functions and methods. |
| |
| - Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a |
| build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead |
| of stdint.h on that platform. |
| |
| - Issue #4856: Remove checks for win NT. |
| |
| - Issue #2016: Fixed a crash in a corner case where the dictionary of keyword |
| arguments could be modified during the function call setup. |
| |
| - Removed the ipaddr module. |
| |
| - Issue #6329: Fixed iteration for memoryview objects (it was being blocked |
| because it wasn't recognized as a sequence). |
| |
| - Issue #6289: Encoding errors from ``compile()`` were being masked. |
| |
| - When no module is given in a relative import, the module field of the |
| ImportFrom AST node is now None instead of an empty string. |
| |
| - Assignment to None using import statements now raises a SyntaxError. |
| |
| - Issue #4547: When debugging a very large function, it was not always possible |
| to update the lineno attribute of the current frame. |
| |
| - Issue #5330: C functions called with keyword arguments were not reported by |
| the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau. |
| |
| - Issue #5982: staticmethod and classmethod now expose the wrapped function with |
| ``__func__``. |
| |
| - Added support for multiple context managers in the same with-statement. |
| Deprecated ``contextlib.nested()`` which is no longer needed. |
| |
| - Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with |
| statement and correctly lookup the __enter__ and __exit__ special methods. |
| |
| - Issue #5829: complex("1e500") no longer raises OverflowError. This makes it |
| consistent with float("1e500") and interpretation of real and imaginary |
| literals. |
| |
| - Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more. |
| |
| - ``__instancecheck__()`` and ``__subclasscheck__()`` are now completely ignored |
| on classic classes and instances. |
| |
| - Issue #5994: The marshal module now has docstrings. |
| |
| - Issue #5981: Fix three minor inf/nan issues in float.fromhex: |
| |
| (1) inf and nan strings with trailing whitespace were incorrectly rejected; |
| (2) parsing of strings representing infinities and nans was locale aware; and |
| (3) the interpretation of fromhex('-nan') didn't match that of float('-nan'). |
| |
| - Issue #5920: For ``float.__format__()``, change the behavior with the empty |
| presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g' |
| but with at least one decimal point and with a default precision |
| of 12. Previously, the behavior the same but with a default precision of 6. |
| This more closely matches ``str()``, and reduces surprises when adding |
| alignment flags to the empty presentation type. This also affects the new |
| complex.__format__ in the same way. |
| |
| - Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by |
| classtype's, even if it was None. property now inserts the __doc__ into the |
| subclass instance __dict__. |
| |
| - Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal |
| sequences. Patch by Nick Barnes and Victor Stinner. |
| |
| - Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3), |
| '.5')`` now produces a sensible result. |
| |
| - Issue #5864: Fix empty format code formatting for floats so that it never |
| gives more than the requested number of significant digits. |
| |
| - Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes new |
| Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h. |
| |
| - Issue #4971: Fix titlecase for characters that are their own titlecase, but |
| not their own uppercase. |
| |

| _PyOS_double_to_string or PyOS_double_to_string. |
| |
| - Issue #5283: Setting __class__ in __del__ caused a segfault. |
| |
| - Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves |
| nans, infs or negative zeros. |
| |
| - Implement PEP 378, Format Specifier for Thousands Separator, for floats, ints, |
| and longs. |
| |
| - Issue #5515: 'n' formatting for ints, longs, and floats handles leading zero |
| formatting poorly. |
| |
| - Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no |
| type code and we have an exponent. |
| |
| - Issue #3166: Make long -> float (and int -> float) conversions correctly |
| rounded. |
| |
| - Issue #5787: ``object.__getattribute__(some_type, "__bases__")`` segfaulted on |
| some built-in types. |
| |
| - Issue #1869: Fix a couple of minor round() issues. ``round(5e15+1)`` was |
| giving 5e15+2; ``round(-0.0)`` was losing the sign of the zero. |
| |
| - Issue #5759: float() didn't call __float__ on str subclasses. |
| |
| - Issue #5704: The "-3" command-line option now implies "-t". |
| |
| - Issue #2170: Refactored ``xml.dom.minidom.normalize``, increasing both its |
| clarity and its speed. |
| |
| - Issue #2396: The memoryview object was backported from Python 3.1. |
| |
| - 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 #4865: On MacOSX /Library/Python/2.7/site-packages is added to the end |
| sys.path, for compatibility with the system install of Python. |
| |
| - Issue #4688: Add a heuristic so that tuples and dicts containing only |
| untrackable objects are not tracked by the garbage collector. This can reduce |
| the size of collections and therefore the garbage collection overhead on |
| long-running programs, depending on their particular use of datatypes. |
| |
| - Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to improve its |
| performance. Long divisions and remainder operations are now between 50% and |
| 150% faster. |
| |
| - Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the |
| internal representation of integers, for performance reasons. Base 2**30 is |
| enabled by default on 64-bit machines. Add --enable-big-digits option to |
| configure, which overrides the default. Add sys.long_info structseq to |
| provide information about the internal format. |
| |
| - Issue #4034: Fix weird attribute error messages of the traceback object. (As a |
| result traceback.__members__ no longer exists.) |
| |
| - Issue #4474: PyUnicode_FromWideChar now converts characters outside the BMP to |
| surrogate pairs, on systems with sizeof(wchar_t) == 4 and sizeof(Py_UNICODE) |
| == 2. |
| |
| - Issue #5237: Allow auto-numbered fields in str.format(). For example: ``'{} |
| {}'.format(1, 2) == '1 2'``. |
| |
| - Issue #3652: Make the 'line' argument for ``warnings.showwarning()`` a |
| requirement. Means the DeprecationWarning from Python 2.6 can go away. |
| |
| - 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 #5260: Long integers now consume less memory: average saving is 2 bytes |
| per long on a 32-bit system and 6 bytes per long on a 64-bit system. |
| |
| - Issue #5186: Reduce hash collisions for objects with no __hash__ method by |
| rotating the object pointer by 4 bits to the right. |
| |
| - Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs: it now |
| forces its argument to double before testing for infinity. |
| |
| - Issue #4978: Passing keyword arguments as unicode strings is now allowed. |
| |
| - Issue #1242657: the __len__() and __length_hint__() calls in several tools |
| were suppressing all exceptions. These include list(), filter(), map(), |
| zip(), and bytearray(). |
| |
| - os.ftruncate raises OSErrors instead of IOErrors for consistency with other os |
| functions. |
| |
| - Issue #4991: Passing invalid file descriptors to io.FileIO now raises an |
| OSError. |
| |
| - Issue #4807: Port the _winreg module to Windows CE. |
| |
| - 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 #3720: Fix a crash when an iterator modifies its class and removes its |
| __next__ method. |
| |
| - Issue #4893: Use NT threading on CE. |
| |
| - Issue #4915: Port sysmodule to Windows CE. |
| |
| - Issue #4074: Change the criteria for doing a full garbage collection (i.e. |
| collecting the oldest generation) so that allocating lots of objects without |
| destroying them does not show quadratic performance. Based on a proposal by |
| Martin von Löwis at |
| http://mail.python.org/pipermail/python-dev/2008-June/080579.html. |
| |
| - Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t. |
| |
| - 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 |
| file with `str' filename on Windows. |
| |
| - Issue #3680: Reference cycles created through a dict, set or deque iterator |
| did not get collected. |
| |
| - Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where |
| the tp_hash and tp_dict slots are both NULL. |
| |
| - Issue #4764: With io.open, IOError.filename is set when trying to open a |
| directory on POSIX systems. |
| |
| - Issue #4764: IOError.filename is set when trying to open a directory on POSIX |
| systems. |
| |
| - Issue #4759: None is now allowed as the first argument of |
| ``bytearray.translate()``. It was always allowed for ``bytes.translate()``. |
| |
| - Added test case to ensure attempts to read from a file opened for writing |
| fail. |
| |
| - 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 #3439: Add a bit_length method to int and long. |
| |
| - Issue #2183: Simplify and optimize bytecode for list comprehensions. Original |
| patch by Neal Norwitz. |
| |
| - Issue #4597: Fixed exception handling when the __exit__ function of a context |
| manager returns a value that cannot be converted to a bool. |
| |
| - Issue #4597: Fixed several opcodes that weren't always propagating exceptions. |
| |
| - Issue #4445: Replace ``sizeof(PyStringObject)`` with |
| ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str |
| instances. On a typical machine this saves 3 bytes of memory (on average) per |
| string allocation. |
| |
| - 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 #3689: The list reversed iterator now supports __length_hint__ instead |
| of __len__. Behavior now matches other reversed iterators. |
| |
| - Issue #4367: Python would segfault during compiling when the unicodedata |
| module couldn't be imported and \N escapes were present. |
| |
| - 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 #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. |
| |
| - Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method |
| does not return iterators for the 4th and 5th items. |
| |
| - Issue #4209: Enabling unicode_literals and the print_function in the same |
| __future__ import didn't work. |
| |
| - Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning |
| because it is a reserved word in 3.x. |
| |
| - On windows, ``os.chdir()`` given unicode was not working if |
| GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful |
| this code path is 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. |
| |
| - Issue #4509: Various issues surrounding resize of bytearray objects to which |
| there are buffer exports. |
| |
| - Issue #4748: Lambda generators no longer return a value. |
| |
| - Issue #3582: Use native TLS functions on Windows |
| |
| - The re.sub(), re.subn() and re.split() functions now accept a flags parameter. |
| |
| - Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short |
| file names. |
| |
| - Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)' |
| to avoid compiler warnings. |
| |
| - Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam() |
| returned them on 64bit platforms. |
| |
| - Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call |
| PyUnicode_DecodeUTF8() once, remember the result and output it in a second |
| step. This avoids problems with counting UTF-8 bytes that ignores the effect |
| of using the replace error handler in PyUnicode_DecodeUTF8(). |
| |
| - Issue #3739: The unicode-internal encoder now reports the number of characters |
| consumed like any other encoder (instead of the number of bytes). |
| |
| - Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc |
| allocator will be automatically disabled when running under Valgrind. This |
| gives improved memory leak detection when running under Valgrind, while taking |
| advantage of pymalloc at other times. |

| support the same flexibility as the CPython command line itself. |
| |

| disabled, and not compiled. |
| |
| - 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 |

| 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 |

| based on __file__). Original patch by Alexander Belopolsky. |
| |
| - Issues #4082 and #4512: Add runpy support to zipimport in a manner that allows |

| Extension Modules |
| ----------------- |
| |
| - Issue #6508: Add posix.{getresuid,getresgid,setresuid,setresgid}. |
| |
| - Issue #7078: Set struct.__doc__ from _struct.__doc__. |
| |
| - Issue #3366: Add erf, erfc, expm1, gamma, lgamma functions to math module. |
| |
| - Issue #6823: Allow time.strftime() to accept a tuple with a isdst field |
| outside of the range of [-1, 1] by normalizing the value to within that range. |
| |
| - Issue #6877: Make it possible to link the readline extension to libedit on |
| OSX. |
| |
| - Issue #6944: Fix a SystemError when socket.getnameinfo() was called with |
| something other than a tuple as first argument. |
| |
| - Issue #6865: Fix reference counting issue in the initialization of the pwd |
| module. |
| |
| - Issue #6848: Fix curses module build failure on OS X 10.6. |
| |
| - Fix a segfault in expat when given a specially crafted input lead to the |
| tokenizer not stopping. CVE-2009-3720. |
| |
| - Issue #6561: '\d' in a regex now matches only characters with Unicode category |
| 'Nd' (Number, Decimal Digit). Previously it also matched characters with |
| category 'No'. |
| |
| - Issue #1523: Remove deprecated overflow wrapping for struct.pack with an |
| integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now |
| consistently raises struct.error. |
| |
| - Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the |
| integer formats ('bBhHiIlLqQ'). In the following, '*' represents any of '=', |
| '<', '>'. |
| |
| - Packing a float now always gives a Deprecation Warning. Previously it |
| only warned for 'I', 'L', '*B', '*H', '*I', '*L'. |
| |
| - If x is not an int, long or float, then packing x will always result in |
| struct.error. Previously an x with an __int__ method could be packed by |
| 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a |
| __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with |
| neither __int__ nor __long__, TypeError used to be raised (with a |
| confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and |
| struct.error in other cases. |
| |
| Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any |
| argument with an __int__ method can be packed, but use of this feature |
| triggers a DeprecationWarning. |
| |

| - Issue #4396: The parser module now correctly validates the with statement. |
| |
| - Issue #5228: Make functools.partial objects can now be pickled. |
| |
| Tests |
| ----- |
| |
| - Issue #7431: Use TESTFN in test_linecache instead of trying to create a file |
| in the Lib/test directory, which might be read-only for the user running the |
| tests. |
| |
| - Issue #7324: Add a sanity check to regrtest argument parsing to catch the case |
| of an option with no handler. |
| |
| - Issue #7312: Add a -F flag to run the selected tests in a loop until a test |
| fails. Can be combined with -j. |
| |
| - Issue #7295: Do not use a hardcoded file name in test_tarfile. |
| |
| - Issue #7270: Add some dedicated unit tests for multi-thread synchronization |
| primitives such as Lock, RLock, Condition, Event and Semaphore. |
| |
| - Issue #7222: Make thread "reaping" more reliable so that reference |
| leak-chasing test runs give sensible results. The previous method of reaping |
| threads could return successfully while some Thread objects were still |
| referenced. This also introduces a new private function: ``thread._count()``. |
| |
| - Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer |
| runs the risk of causing the worker thread to fail. |
| |
| - Issue #7055: test___all__ now greedily detects all modules which have an |
| __all__ attribute, rather than using a hardcoded and incomplete list. |
| |
| - Issue #7058: Added save/restore for things like sys.argv and cwd to |
| runtest_inner in regrtest, with warnings if the called test modifies them, |
| and a new section in the summary report at the end. |
| |
| - Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6. |
| |
| - Issue #6806: test_platform failed under OS X 10.6.0 because ``sw_ver`` leaves |
| off the trailing 0 in the version number. |
| |
| - Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to |
| Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate |
| the same behaviour as test_ttkguionly (and now also test_tk) which is to skip |
| the tests if DISPLAY is defined but can't be used. |
| |
| - Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running |
| regression tests in parallel, shortening the total runtime. |
| |
| - Issue #5354: New test support function import_fresh_module() makes it easy to |
| import both normal and optimised versions of modules. test_heapq and |
| test_warnings have been adjusted to use it, tests for other modules with both |
| C and Python implementations in the stdlib can be adjusted to use it over |
| time. |
| |
| - Fix test_warnings to no longer reset the warnings filter. |
| |
| - Fix test_logging to no longer reset the warnings filter. |
| |
| - Issue #5635: Fix running test_sys with tracing enabled. |
| |
| - regrtest no longer treats ImportError as equivalent to SkipTest. Imports that |
| should cause a test to be skipped are now done using import_module from test |
| support, which does the conversion. |
| |
| - Issue #5083: New 'gui' resource for regrtest. |
| |
| - Issue #5837: Certain sequences of calls to set() and unset() for |
| support.EnvironmentVarGuard objects restored the environment variables |
| incorrectly on __exit__. |
| |
| - Issue #2389: Array objects are now pickled in a portable manner. |
| |
| Misc |
| ---- |
| |
| - Issue #5611: Auto-detect whether a C file uses tabs or spaces in Vim. |
| |

| filename or mode, and the filename is a unicode string. |
| |
| - Bug #3951: Py_USING_MEMORY_DEBUGGER should not be enabled by default. |
| |
| Library |
| ------- |
| |
| - Issue #3965: Allow repeated calls to turtle.Screen, by making it a |
| true singleton object. |
| |

| |
| 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 Tools/scripts/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 #3776: Deprecate the bsddb package for removal in 3.0. |
| |
| - 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. |
| |

| ----------------- |
| |
| - Issue #4301: Patch the logging module to add processName support, remove |
| _check_logger_class from multiprocessing. |
| |
| - 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 #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 a 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. |
| |

| 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 #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. |
| |

| |
| - The PyBytes functions have been renamed to PyByteArray. |
| |
| - The PyString functions have been renamed to PyBytes. A batch of |

| |
| |
| 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. |
| |
| |

| - Added backport of bytearray type. |
| |
| - 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 #2348: add Py3k warning for file.softspace. |
| |
| - Issue #2346/#2347: add Py3k warnings for __methods__ and |

| |
| - Issue #2400: Allow relative imports to "import *". |
| |
| - Issue #1745: Backport print function with ``from __future__ import |
| print_function``. |
| |
| - Issue #2332: add new attribute names for instance method objects. |
| The two changes are: im_self -> __self__ and im_func -> __func__ |
| |
| - Issue #2379: Raise a Py3K warning for __getitem__ or __getslice__ on |
| exception instances. |
| |
| - Issue #2371: Add a Py3k warning when catching an exception that |
| doesn't derive from BaseException. |
| |
| - Issue #2341: Add a Py3k warning when raising an exception that |
| doesn't derive from BaseException. |
| |
| - 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 |
| flags -Wno-long-double, -no-cpp-precomp, and -mno-fused-madd are no |
| longer passed. |
| |
| - Add a warning when asserting a non-empty tuple which is always true. |
| |
| - Issue #2179: speed up with statement execution by storing the exit |
| method on the stack instead of in a temporary variable (patch by |
| Jeffrey Yaskin) |
| |
| - Issue #2238: Some syntax errors in *args and **kwargs expressions |
| could give bogus error messages. |

| - Issue #2315: logging.handlers: TimedRotatingFileHandler now accounts |
| for daylight savings time in calculating the next rollover. |
| |
| - Issue #2316: logging.handlers: TimedRotatingFileHandler now |
| calculates rollovers correctly even when nothing is logged for a |
| while. |
| |
| - Issue #2317: logging.handlers: TimedRotatingFileHandler now uses |
| improved logic for removing old files. |
| |
| - Issue #2495: tokenize.untokenize now inserts a space between two |
| consecutive string literals; previously, ["" ""] was rendered as |
| [""""], which is incorrect python code. |
| |
| - Issue #2248: return the result of the QUIT command. from |
| SMTP.quit(). |
| |
| - Backport of Python 3.0's io module. |
| |
| - Issue #2482: Make sure that the coefficient of a Decimal is always |
| stored as a str instance, not as a unicode instance. This ensures |
| that str(Decimal) is always an instance of str. |
| |
| - Issue #2478: fix failure of decimal.Decimal(0).sqrt() |
| |
| - Issue #2432: give DictReader the dialect and line_num attributes |
| advertised in the docs. |

| in the WWW-Authenticate header. |
| |
| - Issue #2434: Enhanced platform.win32_ver() to also work on Python |
| installation which do not have the win32all package installed. |
| |
| - Added support to platform.uname() to also report the machine and |
| processor information on Windows XP and later. As a result, |
| platform.machine() and platform.processor() will report this |
| information as well. |
| |
| - The library implementing the 2to3 conversion, lib2to3, was added to |
| the standard distribution. |
| |
| - Issue #1747858: Fix chown to work with large uid's and gid's on |
| 64-bit platforms. |
| |
| - Issue #1202: zlib.crc32 and zlib.adler32 no longer return different |
| values on 32-bit vs. 64-bit python interpreters. Both were correct, |
| but they now both return a signed integer object for consistency. |
| |
| - Issue #1158: add %f format (fractions of a second represented as |
| microseconds) to datetime objects. Understood by both strptime and |
| strftime. |
| |
| - Issue #705836: struct.pack(">f", x) now raises OverflowError on all |
| platforms when x is too large to fit into an IEEE 754 float; |
| previously it only raised OverflowError on non IEEE 754 platforms. |
| |
| - Issues #2166, #1741 and #1531505: now distutils deals with HOME |
| correctly under win32 |
| |
| - Patch #1858: distutils: added multiple server support in .pypirc |
| |
| - Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now |
| optional: it defaults to the traceback of the exception that is |
| currently being handled (is mandatory to be in the middle of an |
| exception, otherwise it raises ValueError). |
| |
| - Issue #1193577: A .shutdown() method has been added to SocketServers |
| which terminates the .serve_forever() loop. |
| |
| - Issue #2220: handle rlcompleter attribute match failure more |
| gracefully. |
| |
| - Issue #2225: py_compile, when executed as a script, now returns a |
| non- zero status code if not all files could be compiled |
| successfully. |
| |
| - Bug #1725737: In distutils' sdist, exclude RCS, CVS etc. also in the |
| root directory, and also exclude .hg, .git, .bzr, and _darcs. |
| |
| - Issue #1872: The struct module typecode for _Bool has been changed |
| 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. |
| |

| |
| - Patch #2232: os.tmpfile might fail on Windows if the user has no |
| permission to create files in the root directory. |
| |

| ----- |
| |
| - A new script 2to3 is now installed, to run the 2.x to 3.x converter. |
| |
| - Python/memmove.c and Python/strerror.c have been removed; both |
| functions are in the C89 standard library. |
| |
| - Patch #2284: Add -x64 option to rt.bat. |
| |
| C API |
| ----- |
| |
| - Patch #2477: Added PyParser_ParseFileFlagsEx() and |

| |
| |
| 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: Modified 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 a |
| 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. |
| |

| 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 |
| |

| 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). |

| 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 |

| - 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(). |
| |
| - The pprint module now supports sets and frozensets. |

| specified at connection time. |
| |
| - Bug #1728403: Fix a bug that CJKCodecs StreamReader hangs when it |
| reads a file that ends with incomplete sequence and sizehint |
| argument for .read() is specified. |

| of an infinite recursion check. |
| |
| - Removed plat-freebsd2 and plat-freebsd3 directories (and IN.py in |

| only useful in Unix/Linux environments. |
| |
| - Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file |
| (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 |
| the client's request was successfully received, understood, and |
| accepted. Now in these cases no error is raised in urllib (issue |
| #1177) and urllib2. |
| |

| closes patch #723312. |
| |
| - Patch #1676823: Added create_connection() to socket.py, which may be |
| called with a timeout, and use it from httplib (whose HTTPConnection |

| directories. |
| |
| - Bug #1681228: the webbrowser module now correctly uses the default |
| GNOME or KDE browser, depending on whether there is a session of one |
| of those present. Also, it tries the Windows default browser before |
| trying Mozilla variants. |
| |

| for the debugged script, which means that imports from __main__ work |
| correctly now. |

| |
| - Patch #1393667: pdb now has a "run" command which restarts the |
| debugged Python program, optionally with different arguments. |
| |
| - Patch #1649190: Adding support for _Bool to ctypes as c_bool. |
| |
| - Patch #1530482: add pydoc.render_doc() which returns the |
| documentation for a thing instead of paging it to stdout, which |
| 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 passing custom TestRunner instances to |
| unittest's main() function. |
| |
| - Patches #1550273, #1550272: fix a few bugs in unittest and add a |

| members). |
| |
| - Issue #829951: In the smtplib module, SMTP.starttls() now complies |
| with RFC 3207 and forgets any knowledge obtained from the server not |

| Fenner. |
| |
| - Issue #1339: The smtplib.SMTP class has been refactored a bit such |
| that the SMTP.starttls() caller no longer needs to call ehlo() |
| beforehand. SMTP.starttls() now raises an exception of the server |
| does not claim to support starttls. Adds the |
| SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill |
| Fenner. |

| - 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. |
| |
| - Add the bsddb.db.DBEnv.lock_id_free method. |
| |
| - Bug #1686475: Support stat'ing open files on Windows again. |
| |
| - Patch #1185447: binascii.b2a_qp() now correctly quotes binary |

| 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. |
| |
| - fixed a bug with bsddb.DB.stat: the flags and txn keyword arguments |
| 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. |
| |

| module being tested. Was causing an error by __import__ doing a |
| reload on the second run and thus suppressing bytecode recreation. |
| |
| - Capture socket connection resets and timeouts in test_socket_ssl and |
| test_urllib2net and raise test.test_support.ResourceDenied. |
| |
| - Patch #1559413: Fix test_cmd_line if sys.executable contains a |
| space. |

| used to catch the warnings issued by the warning framework. |
| |
| 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. |

| Build |
| ----- |
| |
| - Have the search path for building extensions follow the declared |
| order in $CPPFLAGS and $LDFLAGS when adding directories from those |
| environment variables. |
| |
| - Bug #1983: Added a check to pyport to verify that sizeof(pid_t) is |
| smaller or equal sizeof(long). |
| |
| - Bug #1234: Fixed semaphore errors on AIX 5.2 |
| |
| - Issue #1726: Remove Python/atof.c from PCBuild/pythoncore.vcproj. |
| |
| - Removed PCbuild8/ directory and added a new build directory for VS |
| 2005 based on the VS 2008 build directory to PC/VS8.0. The script |
| PCbuild/vs8to9.py was added to sync changes from PCbuild to |
| PC/VS8.0. |
| |
| - Moved PCbuild/ directory for VS 2003 to PC/VS7.1 and renamed |
| PCBuild9/ directory to PCBuild/. |
| |
| - Bug #1699: Define _BSD_SOURCE only on OpenBSD. |
| |
| - Bug #1608: use -fwrapv when GCC supports it. This is important, |
| newer GCC versions may optimize away overflow buffer overflow checks |
| without this option! |
| |
| - Patch #1418: Make the AC_REPLACE_FUNCS object files actually work. |
| |
| - Add a FAST_LOOPS build option that speeds-up looping by trading away |
| periodic threadstate and signal checking in tight loops. By |
| default, this option is turned-off. It should only be enabled in |
| debugged, performance critical applications. |
| |
| - Patch #786737: Allow building in a tree of symlinks pointing to a |
| readonly source. |
| |
| - Bug #1737210: Change Manufacturer of Windows installer to PSF. |
| |
| - Bug #1746880: Correctly install DLLs into system32 folder on Win64. |
| |
| - Define _BSD_SOURCE, to get access to POSIX extensions on OpenBSD |
| 4.1+. |
| |
| - Stop supporting AtheOS and cause a build error in configure for the |
| platform. |
| |
| - Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS |
| returned by python-config if Python was built with --enable-shared |
| because that prevented the shared library from being used. |
| |
| - Patch #1569798: fix a bug in distutils when building Python from a |
| directory within sys.exec_prefix. |
| |
| - Bug #1675511: Use -Kpic instead of -xcode=pic32 on Solaris/x86. |
| |
| - Disable _XOPEN_SOURCE on NetBSD 1.x. |
| |
| - configure now checks whether gcc supports the PyArg_ParseTuple |
| format attribute. |
| |
| - Bug #1578513: Cross compilation was broken by a change to configure. |
| Repair so that it's back to how it was in 2.4.3. |
| |
| - Patch #1576954: Update VC6 build directory; remove redundant files |
| in VC7. |
| |
| - Bug #1568842: Fix test for uintptr_t. |
| |
| - 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. |
