| |
| - Patch #1507247: tarfile.py: use current umask for intermediate |
| directories. |
| |
| - Bug #1637022: Prefix AST symbols with _Py_. |
| |
| - Prevent seg fault on shutdown which could occur if an object |
| raised a warning. |
| |
| - Bug #1566280: Explicitly invoke threading._shutdown from Py_Main, |
| to avoid relying on atexit. |
| |
| - Bug #1590891: random.randrange don't return correct value for big number |
| |
| - Patch #1586791: Better exception messages for some operations on strings, |
| tuples and lists. |
| |
| - Bug #1067760: Deprecate passing floats to file.seek. |
| |
| - Bug #1591996: Correctly forward exception in instance_contains(). |
| |
| - Bug #1588287: fix invalid assertion for `1,2` in debug builds. |
| |
| - Bug #1576657: when setting a KeyError for a tuple key, make sure that |
| the tuple isn't used as the "exception arguments tuple". |
| |
| - Bug #1565514, SystemError not raised on too many nested blocks. |
| |
| - Bug #1576174: WindowsError now displays the windows error code |
| again, no longer the posix error code. |
| |
| - Patch #1549049: Support long values in structmember, issue warnings |
| if the assigned value for structmember fields gets truncated. |
| |
| - Update the peephole optimizer to remove more dead code (jumps after returns) |
| and inline unconditional jumps to returns. |
| |
| - Bug #1545497: when given an explicit base, int() did ignore NULs |
| embedded in the string to convert. |
| |
| - Bug #1569998: break inside a try statement (outside a loop) is now |
| recognized and rejected. |
| |
| - list.pop(x) accepts any object x following the __index__ protocol. |
| |
| - Fix some leftovers from the conversion from int to Py_ssize_t |
| (relevant to strings and sequences of more than 2**31 items). |
| |
| - A number of places, including integer negation and absolute value, |
| were fixed to not rely on undefined behaviour of the C compiler |
| anymore. |
| |
| - Bug #1566800: make sure that EnvironmentError can be called with any |
| number of arguments, as was the case in Python 2.4. |
| |
| - Patch #1567691: super() and new.instancemethod() now don't accept |
| keyword arguments any more (previously they accepted them, but didn't |
| use them). |
| |
| - Fix a bug in the parser's future statement handling that led to "with" |
| not being recognized as a keyword after, e.g., this statement: |
| from __future__ import division, with_statement |
| |
| - Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)). |
| |
| - Fix %zd string formatting on Mac OS X so it prints negative numbers. |
| |
| - Allow exception instances to be directly sliced again. |
| |
| - Bug #1551432: Exceptions do not define an explicit __unicode__ method. This |
| allows calling unicode() on exceptions classes directly to succeed. |
| |
| - Make _PyGILState_NoteThreadState() static, it was not used anywhere |
| outside of pystate.c and should not be necessary. |
| |
| - Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack. |
| Also make sure that every exception class has __module__ set to |
| 'exceptions'. |
| |
| - Bug #1550983: emit better error messages for erroneous relative |
| imports (if not in package and if beyond toplevel package). |
| |
| - Overflow checking code in integer division ran afoul of new gcc |
| optimizations. Changed to be more standard-conforming. |
| |
| - Patch #1542451: disallow continue anywhere under a finally. |
| |
| - Patch #1546288: fix seg fault in dict_equal due to ref counting bug. |
| |
| - The return tuple from str.rpartition(sep) is (tail, sep, head) where |
| head is the original string if sep was not found. |
| |
| - Bug #1520864: unpacking singleton tuples in list comprehensions and |
| generator expressions (x for x, in ... ) works again. Fixing this problem |
| required changing the .pyc magic number. This means that .pyc files |
| generated before 2.5c2 will be regenerated. |
| |
| - with and as are now keywords. |
| |
| |

| |
| - Bug #1569790: mailbox.py: Maildir.get_folder() and MH.get_folder() |
| weren't passing the message factory on to newly created Maildir/MH |
| objects. |
| |
| - Patch #1514543: mailbox.py: In the Maildir class, report errors if there's |
| a filename clash instead of possibly losing a message. (Patch by David |
| Watson.) |
| |
| - Patch #1514544: Try to ensure that messages/indexes have been physically |

| fix all codecs file wrappers to work correctly with the "with" |
| statement (bug #1586513). |
| |
| - Lib/modulefinder.py now handles absolute and relative imports |
| correctly. |
| |
| - Patch #1567274: Support SMTP over TLS. |
| |
| - Patch #1560695: Add .note.GNU-stack to ctypes' sysv.S so that |
| ctypes isn't considered as requiring executable stacks. |
| |
| - ctypes callback functions only support 'fundamental' data types as |
| result type. Raise an error when something else is used. This is a |
| partial fix for Bug #1574584. |
| |
| - Fix turtle so that time.sleep is imported for the entire library. Allows |
| the demo2 function to be executed on its own instead of only when the |
| module is run as a script. |
| |
| - Bug #813342: Start the IDLE subprocess with -Qnew if the parent |

| |
| - Made the error message for time.strptime when the data data and format do |
| match be more clear. |
| |
| - Fix a bug in traceback.format_exception_only() that led to an error |
| being raised when print_exc() was called without an exception set. |
| In version 2.4, this printed "None", restored that behavior. |
| |
| - Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because |
| the close_fds arg to subprocess.Popen is not supported). |
| |
| - Reverted patch #1504333 to sgmllib because it introduced an infinite loop. |
| |
| - Patch #1553314: Fix the inspect.py slowdown that was hurting IPython & SAGE |
| by adding smarter caching in inspect.getmodule() |
| |
| - Fix missing import of the types module in logging.config. |

| function now accepts tuples as well as lists. |
| |
| - Bug #1541863: uuid.uuid1 failed to generate unique identifiers |
| on systems with low clock resolution. |
| |
| - Bug #1531862: Do not close standard file descriptors in subprocess. |

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

| |
| |

| types. |
| |
| - Patch #1610575: The struct module now supports the 't' code, for |
| C99 _Bool. |

| return negative numbers, per the underlying C implementation. |
| |
| - Patch #1544279: Improve thread-safety of the socket module by moving |
| the sock_addr_t storage out of the socket object. |
| |
| - Speed up function calls into the math module. |
| |
| - Bug #1588217: don't parse "= " as a soft line break in binascii's |

| method does, instead of converting it to a raw buffer. |
| |
| - Patch #1572724: fix typo ('=' instead of '==') in _msi.c. |
| |
| - Bug #1572832: fix a bug in ISO-2022 codecs which may cause segfault |

| |
| - Added support for linking the bsddb module against BerkeleyDB 4.5.x. |
| |

| context manager so that one can temporarily set or unset environment |
| variables. |
| |
| - Added guard_warnings_filter to test.test_support. It returns a context |
| manager that protects the 'warnings' module's filter from being mutated |
| once the context has been exited. |
| |

| |
| What's New in Python 2.5 release candidate 1? |
| ============================================= |
| |
| *Release date: 17-AUG-2006* |
| |
| Core and builtins |
| ----------------- |
| |
| - Unicode objects will no longer raise an exception when being |
| compared equal or unequal to a string and a UnicodeDecodeError |
| exception occurs, e.g. as result of a decoding failure. |
| |
| Instead, the equal (==) and unequal (!=) comparison operators will |
| now issue a UnicodeWarning and interpret the two objects as |
| unequal. The UnicodeWarning can be filtered as desired using |
| the warning framework, e.g. silenced completely, turned into an |
| exception, logged, etc. |
| |
| Note that compare operators other than equal and unequal will still |
| raise UnicodeDecodeError exceptions as they've always done. |
| |
| - Fix segfault when doing string formatting on subclasses of long. |
| |
| - Fix bug related to __len__ functions using values > 2**32 on 64-bit machines |
| with new-style classes. |
| |
| - Fix bug related to __len__ functions returning negative values with |
| classic classes. |
| |
| - Patch #1538606, Fix __index__() clipping. There were some problems |
| discovered with the API and how integers that didn't fit into Py_ssize_t |
| were handled. This patch attempts to provide enough alternatives |
| to effectively use __index__. |
| |
| - Bug #1536021: __hash__ may now return long int; the final hash |
| value is obtained by invoking hash on the long int. |
| |
| - Bug #1536786: buffer comparison could emit a RuntimeWarning. |
| |
| - Bug #1535165: fixed a segfault in input() and raw_input() when |
| sys.stdin is closed. |
| |
| - On Windows, the PyErr_Warn function is now exported from |
| the Python dll again. |
| |
| - Bug #1191458: tracing over for loops now produces a line event |
| on each iteration. Fixing this problem required changing the .pyc |
| magic number. This means that .pyc files generated before 2.5c1 |
| will be regenerated. |
| |
| - Bug #1333982: string/number constants were inappropriately stored |
| in the byte code and co_consts even if they were not used, ie |
| immediately popped off the stack. |
| |
| - Fixed a reference-counting problem in property(). |
| |
| |
| Library |
| ------- |
| |
| - Fix a bug in the ``compiler`` package that caused invalid code to be |
| generated for generator expressions. |
| |
| - The distutils version has been changed to 2.5.0. The change to |
| keep it programmatically in sync with the Python version running |
| the code (introduced in 2.5b3) has been reverted. It will continue |
| to be maintained manually as static string literal. |
| |
| - If the Python part of a ctypes callback function returns None, |
| and this cannot be converted to the required C type, an exception is |
| printed with PyErr_WriteUnraisable. Before this change, the C |
| callback returned arbitrary values to the calling code. |
| |
| - The __repr__ method of a NULL ctypes.py_object() no longer raises |
| an exception. |
| |
| - uuid.UUID now has a bytes_le attribute. This returns the UUID in |
| little-endian byte order for Windows. In addition, uuid.py gained some |
| workarounds for clocks with low resolution, to stop the code yielding |
| duplicate UUIDs. |
| |
| - Patch #1540892: site.py Quitter() class attempts to close sys.stdin |
| before raising SystemExit, allowing IDLE to honor quit() and exit(). |
| |
| - Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize. |
| |
| - Patch #1536071: trace.py should now find the full module name of a |
| file correctly even on Windows. |
| |
| - logging's atexit hook now runs even if the rest of the module has |
| already been cleaned up. |
| |
| - Bug #1112549, fix DoS attack on cgi.FieldStorage. |
| |
| - Bug #1531405, format_exception no longer raises an exception if |
| str(exception) raised an exception. |
| |
| - Fix a bug in the ``compiler`` package that caused invalid code to be |
| generated for nested functions. |
| |
| |
| Extension Modules |
| ----------------- |
| |
| - Patch #1511317: don't crash on invalid hostname (alias) info. |
| |
| - Patch #1535500: fix segfault in BZ2File.writelines and make sure it |
| raises the correct exceptions. |
| |
| - Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The |
| '-no-stack-protector' compiler flag for OpenBSD has been removed. |
| |
| - Patch #1532975 was applied, which fixes Bug #1533481: ctypes now |
| uses the _as_parameter_ attribute when objects are passed to foreign |
| function calls. The ctypes version number was changed to 1.0.1. |
| |
| - Bug #1530559, struct.pack raises TypeError where it used to convert. |
| Passing float arguments to struct.pack when integers are expected |
| now triggers a DeprecationWarning. |
| |
| |
| Tests |
| ----- |
| |
| - test_socketserver should now work on cygwin and not fail sporadically |
| on other platforms. |
| |
| - test_mailbox should now work on cygwin versions 2006-08-10 and later. |
| |
| - Bug #1535182: really test the xreadlines() method of bz2 objects. |
| |
| - test_threading now skips testing alternate thread stack sizes on |
| platforms that don't support changing thread stack size. |
| |
| |
| Documentation |
| ------------- |
| |
| - Patch #1534922: unittest docs were corrected and enhanced. |
| |
| |
| Build |
| ----- |
| |
| - Bug #1535502, build _hashlib on Windows, and use masm assembler |
| code in OpenSSL. |
| |
| - Bug #1534738, win32 debug version of _msi should be _msi_d.pyd. |
| |
| - Bug #1530448, ctypes build failure on Solaris 10 was fixed. |
| |
| |
| C API |

| - New API for Unicode rich comparisons: PyUnicode_RichCompare() |
| |
| - Bug #1069160. Internal correctness changes were made to |
| ``PyThreadState_SetAsyncExc()``. A test case was added, and |
| the documentation was changed to state that the return value |
| is always 1 (normal) or 0 (if the specified thread wasn't found). |
| |
| |
| What's New in Python 2.5 beta 3? |
| ================================ |
| |
| *Release date: 03-AUG-2006* |
| |
| Core and builtins |
| ----------------- |
| |
| - _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously |
| returned a long (see PEP 353). |
| |
| - Bug #1515471: string.replace() accepts character buffers again. |
| |
| - Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn(). |
| This provides the proper warning for struct.pack(). |
| PyErr_Warn() is now deprecated in favor of PyErr_WarnEx(). |
| |
| - Patch #1531113: Fix augmented assignment with yield expressions. |
| Also fix a SystemError when trying to assign to yield expressions. |
| |
| - Bug #1529871: The speed enhancement patch #921466 broke Python's compliance |
| with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is |
| used in ``sys.path_importer_cache`` to cache non-directory paths and avoid |
| excessive filesystem operations during imports. |
| |
| - Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some |
| operations on signed longs that are formally undefined by C. |
| Unfortunately, at least one compiler now cares about that, so complicated |
| the code to make that compiler happy again. |
| |
| - Bug #1524310: Properly report errors from FindNextFile in os.listdir. |
| |
| - Patch #1232023: Stop including current directory in search |
| path on Windows. |
| |
| - Fix some potential crashes found with failmalloc. |
| |
| - Fix warnings reported by Klocwork's static analysis tool. |
| |
| - Bug #1512814, Fix incorrect lineno's when code within a function |
| had more than 255 blank lines. |
| |
| - Patch #1521179: Python now accepts the standard options ``--help`` and |
| ``--version`` as well as ``/?`` on Windows. |
| |
| - Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works |
| again. Fixing this problem required changing the .pyc magic number. |
| This means that .pyc files generated before 2.5b3 will be regenerated. |
| |
| - Bug #1524317: Compiling Python ``--without-threads`` failed. |
| The Python core compiles again, and, in a build without threads, the |
| new ``sys._current_frames()`` returns a dictionary with one entry, |
| mapping the faux "thread id" 0 to the current frame. |
| |
| - Bug #1525447: build on MacOS X on a case-sensitive filesystem. |
| |
| |
| Library |
| ------- |
| |
| - Correction of patch #1455898: In the mbcs decoder, set final=False |
| for stream decoder, but final=True for the decode function. |
| |
| - os.urandom no longer masks unrelated exceptions like SystemExit or |
| KeyboardInterrupt. |
| |
| - Bug #1525866: Don't copy directory stat times in |
| shutil.copytree on Windows |
| |
| - Bug #1002398: The documentation for os.path.sameopenfile now correctly |
| refers to file descriptors, not file objects. |
| |
| - The renaming of the xml package to xmlcore, and the import hackery done |
| to make it appear at both names, has been removed. Bug #1511497, |
| #1513611, and probably others. |
| |
| - Bug #1441397: The compiler module now recognizes module and function |
| docstrings correctly as it did in Python 2.4. |
| |
| - Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally |
| lost that tests are sorted by name before being run. This rarely |
| matters for well-written tests, but can create baffling symptoms if |
| side effects from one test to the next affect outcomes. ``DocTestFinder`` |
| has been changed to sort the list of tests it returns. |
| |
| - The distutils version has been changed to 2.5.0, and is now kept |
| in sync with sys.version_info[:3]. |
| |
| - Bug #978833: Really close underlying socket in _socketobject.close. |
| |
| - Bug #1459963: urllib and urllib2 now normalize HTTP header names with |
| title(). |
| |
| - Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback |
| to recursive calls and call it with the failing package name. |
| |
| - Bug #1525817: Don't truncate short lines in IDLE's tool tips. |
| |
| - Patch #1515343: Fix printing of deprecated string exceptions with a |
| value in the traceback module. |
| |
| - Resync optparse with Optik 1.5.3: minor tweaks for/to tests. |
| |
| - Patch #1524429: Use repr() instead of backticks in Tkinter again. |
| |
| - Bug #1520914: Change time.strftime() to accept a zero for any position in its |
| argument tuple. For arguments where zero is illegal, the value is forced to |
| the minimum value that is correct. This is to support an undocumented but |
| common way people used to fill in inconsequential information in the time |
| tuple pre-2.4. |
| |
| - Patch #1220874: Update the binhex module for Mach-O. |
| |
| - The email package has improved RFC 2231 support, specifically for |
| recognizing the difference between encoded (name*0*=<blah>) and non-encoded |
| (name*0=<blah>) parameter continuations. This may change the types of |
| values returned from email.message.Message.get_param() and friends. |
| Specifically in some cases where non-encoded continuations were used, |
| get_param() used to return a 3-tuple of (None, None, string) whereas now it |
| will just return the string (since non-encoded continuations don't have |
| charset and language parts). |
| |
| Also, whereas % values were decoded in all parameter continuations, they are |
| now only decoded in encoded parameter parts. |
| |
| - Bug #1517990: IDLE keybindings on MacOS X now work correctly |
| |
| - Bug #1517996: IDLE now longer shows the default Tk menu when a |
| path browser, class browser or debugger is the frontmost window on MacOS X |
| |
| - Patch #1520294: Support for getset and member descriptors in types.py, |
| inspect.py, and pydoc.py. Specifically, this allows for querying the type |
| of an object against these built-in types and more importantly, for getting |
| their docstrings printed in the interactive interpreter's help() function. |
| |
| |
| Extension Modules |
| ----------------- |
| |
| - Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during |
| a socket operation on a socket with a timeout, the exception will be |
| caught correctly. Previously, the exception was not caught. |
| |
| - Patch #1529514: The _ctypes extension is now compiled on more |
| openbsd target platforms. |
| |
| - The ``__reduce__()`` method of the new ``collections.defaultdict`` had |
| a memory leak, affecting pickles and deep copies. |
| |
| - Bug #1471938: Fix curses module build problem on Solaris 8; patch by |
| Paul Eggert. |
| |
| - Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry. |
| |
| - Patch #1521817: Index range checking on ctypes arrays containing |
| exactly one element enabled again. This allows iterating over these |
| arrays, without the need to check the array size before. |
| |
| - Bug #1521375: When the code in ctypes.util.find_library was |
| run with root privileges, it could overwrite or delete |
| /dev/null in certain cases; this is now fixed. |
| |
| - Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the |
| default mode for loading shared libraries in ctypes. |
| |
| - Because of a misspelled preprocessor symbol, ctypes was always |
| compiled without thread support; this is now fixed. |
| |
| - pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename |
| methods now allow their database parameter to be None as the |
| sleepycat API allows. |
| |
| - Bug #1526460: Fix socketmodule compile on NetBSD as it has a different |
| bluetooth API compared with Linux and FreeBSD. |
| |
| Tests |
| ----- |
| |
| - Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of |
| how long the test file should take to play. Now accepts taking 2.93 secs |
| (exact time) +/- 10% instead of the hard-coded 3.1 sec. |
| |
| - Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``, |
| ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when |
| run via ``regrtest.py``. Now they do. |
| |
| Build |
| ----- |
| |
| - Bug #1439538: Drop usage of test -e in configure as it is not portable. |
| |
| Mac |
| --- |
| |
| - PythonLauncher now works correctly when the path to the script contains |
| characters that are treated specially by the shell (such as quotes). |
| |
| - Bug #1527397: PythonLauncher now launches scripts with the working directory |
| set to the directory that contains the script instead of the user home |
| directory. That latter was an implementation accident and not what users |
| expect. |
| |
| |
| What's New in Python 2.5 beta 2? |
| ================================ |
| |
| *Release date: 11-JUL-2006* |
| |
| Core and builtins |
| ----------------- |
| |
| - Bug #1441486: The literal representation of -(sys.maxint - 1) |
| again evaluates to a int object, not a long. |
| |
| - Bug #1501934: The scope of global variables that are locally assigned |
| using augmented assignment is now correctly determined. |
| |
| - Bug #927248: Recursive method-wrapper objects can now safely |
| be released. |
| |
| - Bug #1417699: Reject locale-specific decimal point in float() |
| and atof(). |
| |
| - Bug #1511381: codec_getstreamcodec() in codec.c is corrected to |
| omit a default "error" argument for NULL pointer. This allows |
| the parser to take a codec from cjkcodecs again. |
| |
| - Bug #1519018: 'as' is now validated properly in import statements. |
| |
| - On 64 bit systems, int literals that use less than 64 bits are |
| now ints rather than longs. |
| |
| - Bug #1512814, Fix incorrect lineno's when code at module scope |
| started after line 256. |
| |
| - New function ``sys._current_frames()`` returns a dict mapping thread |
| id to topmost thread stack frame. This is for expert use, and is |
| especially useful for debugging application deadlocks. The functionality |
| was previously available in Fazal Majid's ``threadframe`` extension |
| module, but it wasn't possible to do this in a wholly threadsafe way from |
| an extension. |
| |
| Library |
| ------- |
| |
| - Bug #1257728: Mention Cygwin in distutils error message about a missing |
| VS 2003. |
| |
| - Patch #1519566: Update turtle demo, make begin_fill idempotent. |
| |
| - Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK |
| environment variable to be set in order to the SDK environment |
| for finding the compiler, include files, etc. |
| |
| - Bug #1515998: Properly generate logical ids for files in bdist_msi. |
| |
| - warnings.py now ignores ImportWarning by default |
| |
| - string.Template() now correctly handles tuple-values. Previously, |
| multi-value tuples would raise an exception and single-value tuples would |
| be treated as the value they contain, instead. |
| |
| - Bug #822974: Honor timeout in telnetlib.{expect,read_until} |
| even if some data are received. |
| |
| - Bug #1267547: Put proper recursive setup.py call into the |
| spec file generated by bdist_rpm. |
| |
| - Bug #1514693: Update turtle's heading when switching between |
| degrees and radians. |
| |
| - Reimplement turtle.circle using a polyline, to allow correct |
| filling of arcs. |
| |
| - Bug #1514703: Only setup canvas window in turtle when the canvas |
| is created. |
| |
| - Bug #1513223: .close() of a _socketobj now releases the underlying |
| socket again, which then gets closed as it becomes unreferenced. |
| |
| - Bug #1504333: Make sgmllib support angle brackets in quoted |
| attribute values. |
| |
| - Bug #853506: Fix IPv6 address parsing in unquoted attributes in |
| sgmllib ('[' and ']' were not accepted). |
| |
| - Fix a bug in the turtle module's end_fill function. |
| |
| - Bug #1510580: The 'warnings' module improperly required that a Warning |
| category be either a types.ClassType and a subclass of Warning. The proper |
| check is just that it is a subclass with Warning as the documentation states. |
| |
| - The compiler module now correctly compiles the new try-except-finally |
| statement (bug #1509132). |
| |
| - The wsgiref package is now installed properly on Unix. |
| |
| - A bug was fixed in logging.config.fileConfig() which caused a crash on |
| shutdown when fileConfig() was called multiple times. |
| |
| - The sqlite3 module did cut off data from the SQLite database at the first |
| null character before sending it to a custom converter. This has been fixed |
| now. |
| |
| Extension Modules |
| ----------------- |
| |
| - #1494314: Fix a regression with high-numbered sockets in 2.4.3. This |
| means that select() on sockets > FD_SETSIZE (typically 1024) work again. |
| The patch makes sockets use poll() internally where available. |
| |
| - Assigning None to pointer type fields in ctypes structures possible |
| overwrote the wrong fields, this is fixed now. |
| |
| - Fixed a segfault in _ctypes when ctypes.wintypes were imported |
| on non-Windows platforms. |
| |
| - Bug #1518190: The ctypes.c_void_p constructor now accepts any |
| integer or long, without range checking. |
| |
| - Patch #1517790: It is now possible to use custom objects in the ctypes |
| foreign function argtypes sequence as long as they provide a from_param |
| method, no longer is it required that the object is a ctypes type. |
| |
| - The '_ctypes' extension module now works when Python is configured |
| with the --without-threads option. |
| |
| - Bug #1513646: os.access on Windows now correctly determines write |
| access, again. |
| |
| - Bug #1512695: cPickle.loads could crash if it was interrupted with |
| a KeyboardInterrupt. |
| |
| - Bug #1296433: parsing XML with a non-default encoding and |
| a CharacterDataHandler could crash the interpreter in pyexpat. |
| |
| - Patch #1516912: improve Modules support for OpenVMS. |
| |
| Build |
| ----- |
| |
| - Automate Windows build process for the Win64 SSL module. |
| |
| - 'configure' now detects the zlib library the same way as distutils. |
| Previously, the slight difference could cause compilation errors of the |
| 'zlib' module on systems with more than one version of zlib. |
| |
| - The MSI compileall step was fixed to also support a TARGETDIR |
| with spaces in it. |
| |
| - Bug #1517388: sqlite3.dll is now installed on Windows independent |
| of Tcl/Tk. |
| |
| - Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old |
| trying to be installed even though it's empty. |
| |
| Tests |
| ----- |
| |
| - Call os.waitpid() at the end of tests that spawn child processes in order |
| to minimize resources (zombies). |
| |
| Documentation |
| ------------- |
| |
| - Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the |
| documentation for the warnings module. |
| |
| - Patch #1509163: MS Toolkit Compiler no longer available. |
| |
| - Patch #1504046: Add documentation for xml.etree. |
| |
| |
| What's New in Python 2.5 beta 1? |
| ================================ |
| |
| *Release date: 20-JUN-2006* |
| |
| Core and builtins |
| ----------------- |
| |
| - Patch #1507676: Error messages returned by invalid abstract object operations |
| (such as iterating over an integer) have been improved and now include the |
| type of the offending object to help with debugging. |
| |
| - Bug #992017: A classic class that defined a __coerce__() method that returned |
| its arguments swapped would infinitely recurse and segfault the interpreter. |
| |
| - Fix the socket tests so they can be run concurrently. |
| |
| - Removed 5 integers from C frame objects (PyFrameObject). |
| f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted. |
| |
| - Bug #532646: object.__call__() will continue looking for the __call__ |
| attribute on objects until one without one is found. This leads to recursion |
| when you take a class and set its __call__ attribute to an instance of the |
| class. Originally fixed for classic classes, but this fix is for new-style. |
| Removes the infinite_rec_3 crasher. |
| |
| - The string and unicode methods startswith() and endswith() now accept |
| a tuple of prefixes/suffixes to look for. Implements RFE #1491485. |
| |
| - Buffer objects, at the C level, never used the char buffer |
| implementation even when the char buffer for the wrapped object was |
| explicitly requested (originally returned the read or write buffer). |
| Now a TypeError is raised if the char buffer is not present but is |
| requested. |
| |
| - Patch #1346214: Statements like "if 0: suite" are now again optimized |
| away like they were in Python 2.4. |
| |
| - Builtin exceptions are now full-blown new-style classes instead of |
| instances pretending to be classes, which speeds up exception handling |
| by about 80% in comparison to 2.5a2. |
| |
| - Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to |
| Unicode 4.1. |
| |
| - Patch #921466: sys.path_importer_cache is now used to cache valid and |
| invalid file paths for the built-in import machinery which leads to |
| fewer open calls on startup. |
| |
| - Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power- |
| of-2 bases. The largest speedup is for inputs with about 1000 decimal |
| digits. Conversion from non-power-of-2 bases remains quadratic-time in |
| the number of input digits (it was and remains linear-time for bases |
| 2, 4, 8, 16 and 32). |
| |
| - Bug #1334662: ``int(string, base)`` could deliver a wrong answer |
| when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented |
| an integer close to ``sys.maxint``. This was repaired by patch |
| #1335972, which also gives a nice speedup. |
| |
| - Patch #1337051: reduced size of frame objects. |
| |
| - PyErr_NewException now accepts a tuple of base classes as its |
| "base" parameter. |
| |
| - Patch #876206: function call speedup by retaining allocated frame |
| objects. |
| |
| - Bug #1462152: file() now checks more thoroughly for invalid mode |
| strings and removes a possible "U" before passing the mode to the |
| C library function. |
| |
| - Patch #1488312, Fix memory alignment problem on SPARC in unicode |
| |
| - Bug #1487966: Fix SystemError with conditional expression in assignment |
| |
| - WindowsError now has two error code attributes: errno, which carries |
| the error values from errno.h, and winerror, which carries the error |
| values from winerror.h. Previous versions put the winerror.h values |
| (from GetLastError()) into the errno attribute. |
| |
| - Patch #1475845: Raise IndentationError for unexpected indent. |
| |
| - Patch #1479181: split open() and file() from being aliases for each other. |
| |
| - Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()`` |
| methods were always silently ignored by dictionaries when comparing keys. |
| They are now passed through (except when using the C API function |
| ``PyDict_GetItem()``, whose semantics did not change). |
| |
| - Bug #1456209: In some obscure cases it was possible for a class with a |
| custom ``__eq__()`` method to confuse dict internals when class instances |
| were used as a dict's keys and the ``__eq__()`` method mutated the dict. |
| No, you don't have any code that did this ;-) |
| |
| Extension Modules |
| ----------------- |
| |
| - Bug #1295808: expat symbols should be namespaced in pyexpat |
| |
| - Patch #1462338: Upgrade pyexpat to expat 2.0.0 |
| |
| - Change binascii.hexlify to accept a read-only buffer instead of only a char |
| buffer and actually follow its documentation. |
| |
| - Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder. |
| |
| - Patch #1478788 (modified version): The functional extension module has |
| been renamed to _functools and a functools Python wrapper module added. |
| This provides a home for additional function related utilities that are |
| not specifically about functional programming. See PEP 309. |
| |
| - Patch #1493701: performance enhancements for struct module. |
| |
| - Patch #1490224: time.altzone is now set correctly on Cygwin. |
| |
| - Patch #1435422: zlib's compress and decompress objects now have a |
| copy() method. |
| |
| - Patch #1454481: thread stack size is now tunable at runtime for thread |
| enabled builds on Windows and systems with Posix threads support. |
| |
| - On Win32, os.listdir now supports arbitrarily-long Unicode path names |
| (up to the system limit of 32K characters). |
| |
| - Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}. |
| As a result, these functions now raise WindowsError instead of OSError. |
| |
| - ``time.clock()`` on Win64 should use the high-performance Windows |
| ``QueryPerformanceCounter()`` now (as was already the case on 32-bit |
| Windows platforms). |
| |
| - Calling Tk_Init twice is refused if the first call failed as that |
| may deadlock. |
| |
| - bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to |
| accept it without potentially using an uninitialized pointer. |
| |
| - bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods |
| assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF |
| patch numbers 1494885 and 1494902] |
| |
| - bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class. |
| [pybsddb project SF patch number 1466734] |
| |
| - bsddb: fix DBCursor.pget() bug with keyword argument names when no data |
| parameter is supplied. [SF pybsddb bug #1477863] |
| |
| - bsddb: the __len__ method of a DB object has been fixed to return correct |
| results. It could previously incorrectly return 0 in some cases. |
| Fixes SF bug 1493322 (pybsddb bug 1184012). |
| |
| - bsddb: the bsddb.dbtables Modify method now raises the proper error and |
| aborts the db transaction safely when a modifier callback fails. |
| Fixes SF python patch/bug #1408584. |
| |
| - bsddb: multithreaded DB access using the simple bsddb module interface |
| now works reliably. It has been updated to use automatic BerkeleyDB |
| deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry |
| database calls that would previously deadlock. [SF python bug #775414] |
| |
| - Patch #1446489: add support for the ZIP64 extensions to zipfile. |
| |
| - Patch #1506645: add Python wrappers for the curses functions |
| is_term_resized, resize_term and resizeterm. |
| |
| Library |
| ------- |
| |
| - Patch #815924: Restore ability to pass type= and icon= in tkMessageBox |
| functions. |
| |
| - Patch #812986: Update turtle output even if not tracing. |
| |
| - Patch #1494750: Destroy master after deleting children in |
| Tkinter.BaseWidget. |
| |
| - Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap. |
| |
| - Patch #763580: Add name and value arguments to Tkinter variable |
| classes. |
| |
| - Bug #1117556: SimpleHTTPServer now tries to find and use the system's |
| mime.types file for determining MIME types. |
| |
| - Bug #1339007: Shelf objects now don't raise an exception in their |
| __del__ method when initialization failed. |
| |
| - Patch #1455898: The MBCS codec now supports the incremental mode for |
| double-byte encodings. |
| |
| - ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to |
| guarantee that adjacent triples in the return list always describe |
| non-adjacent blocks. Previously, a pair of matching blocks could end |
| up being described by multiple adjacent triples that formed a partition |
| of the matching pair. |
| |
| - Bug #1498146: fix optparse to handle Unicode strings in option help, |
| description, and epilog. |
| |
| - Bug #1366250: minor optparse documentation error. |
| |
| - Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately; |
| clarify docs. |
| |
| - The wsgiref package has been added to the standard library. |
| |
| - The functions update_wrapper() and wraps() have been added to the functools |
| module. These make it easier to copy relevant metadata from the original |
| function when writing wrapper functions. |
| |
| - The optional ``isprivate`` argument to ``doctest.testmod()``, and the |
| ``doctest.is_private()`` function, both deprecated in 2.4, were removed. |
| |
| - Patch #1359618: Speed up charmap encoder by using a trie structure |
| for lookup. |
| |
| - The functions in the ``pprint`` module now sort dictionaries by key |
| before computing the display. Before 2.5, ``pprint`` sorted a dictionary |
| if and only if its display required more than one line, although that |
| wasn't documented. The new behavior increases predictability; e.g., |
| using ``pprint.pprint(a_dict)`` in a doctest is now reliable. |
| |
| - Patch #1497027: try HTTP digest auth before basic auth in urllib2 |
| (thanks for J. J. Lee). |
| |
| - Patch #1496206: improve urllib2 handling of passwords with respect to |
| default HTTP and HTTPS ports. |
| |
| - Patch #1080727: add "encoding" parameter to doctest.DocFileSuite. |
| |
| - Patch #1281707: speed up gzip.readline. |
| |
| - Patch #1180296: Two new functions were added to the locale module: |
| format_string() to get the effect of "format % items" but locale-aware, |
| and currency() to format a monetary number with currency sign. |
| |
| - Patch #1486962: Several bugs in the turtle Tk demo module were fixed |
| and several features added, such as speed and geometry control. |
| |
| - Patch #1488881: add support for external file objects in bz2 compressed |
| tarfiles. |
| |
| - Patch #721464: pdb.Pdb instances can now be given explicit stdin and |
| stdout arguments, making it possible to redirect input and output |
| for remote debugging. |
| |
| - Patch #1484695: Update the tarfile module to version 0.8. This fixes |
| a couple of issues, notably handling of long file names using the |
| GNU LONGNAME extension. |
| |
| - Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a |
| new flag when ``name`` is already the name of an option flag. |
| |
| - Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler |
| package. |
| |
| - Patch #1472854: make the rlcompleter.Completer class usable on non- |
| UNIX platforms. |
| |
| - Patch #1470846: fix urllib2 ProxyBasicAuthHandler. |
| |
| - Bug #1472827: correctly escape newlines and tabs in attribute values in |
| the saxutils.XMLGenerator class. |
| |
| |

| What's New in Python 2.5 alpha 2? |
| ================================= |
| |
| *Release date: 27-APR-2006* |
| |
| Core and builtins |
| ----------------- |
| |
| - Bug #1465834: 'bdist_wininst preinstall script support' was fixed |
| by converting these apis from macros into exported functions again: |
| |
| PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile |
| PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx |
| PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne |
| PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString |
| PyRun_String Py_CompileString |
| |
| - Under COUNT_ALLOCS, types are not necessarily immortal anymore. |
| |
| - All uses of PyStructSequence_InitType have been changed to initialize |
| the type objects only once, even if the interpreter is initialized |
| multiple times. |
| |
| - Bug #1454485, array.array('u') could crash the interpreter. This was |
| due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings) |
| to unicode when it didn't make sense. 'u#' now requires a unicode string. |
| |
| - Py_UNICODE is unsigned. It was always documented as unsigned, but |
| due to a bug had a signed value in previous versions. |
| |
| - Patch #837242: ``id()`` of any Python object always gives a positive |
| number now, which might be a long integer. ``PyLong_FromVoidPtr`` and |
| ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has |
| never been correct to implement a ``__hash()__`` method that returns the |
| ``id()`` of an object: |
| |
| def __hash__(self): |
| return id(self) # WRONG |
| |
| because a hash result must be a (short) Python int but it was always |
| possible for ``id()`` to return a Python long. However, because ``id()`` |
| could return negative values before, on a 32-bit box an ``id()`` result |
| was always usable as a hash value before this patch. That's no longer |
| necessarily so. |
| |
| - Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c) |
| to load extension modules and now provides the dl module. As a result, |
| sys.setdlopenflags() now works correctly on these systems. (SF patch |
| #1454844) |
| |
| - Patch #1463867: enhanced garbage collection to allow cleanup of cycles |
| involving generators that have paused outside of any ``try`` or ``with`` |
| blocks. (In 2.5a1, a paused generator that was part of a reference |
| cycle could not be garbage collected, regardless of whether it was |
| paused in a ``try`` or ``with`` block.) |
| |
| Extension Modules |
| ----------------- |
| |
| - Patch #1191065: Fix preprocessor problems on systems where recvfrom |
| is a macro. |
| |
| - Bug #1467952: os.listdir() now correctly raises an error if readdir() |
| fails with an error condition. |
| |
| - Fixed bsddb.db.DBError derived exceptions so they can be unpickled. |
| |
| - Bug #1117761: bsddb.*open() no longer raises an exception when using |
| the cachesize parameter. |
| |
| - Bug #1149413: bsddb.*open() no longer raises an exception when using |
| a temporary db (file=None) with the 'n' flag to truncate on open. |
| |
| - Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3 |
| as older versions cause excessive test failures. |
| |
| - Patch #1062014: AF_UNIX sockets under Linux have a special |
| abstract namespace that is now fully supported. |
| |
| Library |
| ------- |
| |
| - Bug #1223937: subprocess.CalledProcessError reports the exit status |
| of the process using the returncode attribute, instead of |
| abusing errno. |
| |
| - Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes |
| a doctest to be skipped (the code is not run, and the expected output |
| or exception is ignored). |
| |
| - Fixed contextlib.nested to cope with exceptions being raised and |
| caught inside exit handlers. |
| |
| - Updated optparse module to Optik 1.5.1 (allow numeric constants in |
| hex, octal, or binary; add ``append_const`` action; keep going if |
| gettext cannot be imported; added ``OptionParser.destroy()`` method; |
| added ``epilog`` for better help generation). |
| |
| - Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when |
| called from a thread spawned as a side effect of importing a module. |
| |
| - The pydoc module now supports documenting packages contained in |
| .zip or .egg files. |
| |
| - The pkgutil module now has several new utility functions, such |
| as ``walk_packages()`` to support working with packages that are either |
| in the filesystem or zip files. |
| |
| - The mailbox module can now modify and delete messages from |
| mailboxes, in addition to simply reading them. Thanks to Gregory |
| K. Johnson for writing the code, and to the 2005 Google Summer of |
| Code for funding his work. |
| |
| - The ``__del__`` method of class ``local`` in module ``_threading_local`` |
| returned before accomplishing any of its intended cleanup. |
| |
| - Patch #790710: Add breakpoint command lists in pdb. |
| |
| - Patch #1063914: Add Tkinter.Misc.clipboard_get(). |
| |
| - Patch #1191700: Adjust column alignment in bdb breakpoint lists. |
| |
| - SimpleXMLRPCServer relied on the fcntl module, which is unavailable on |
| Windows. Bug #1469163. |
| |
| - The warnings, linecache, inspect, traceback, site, and doctest modules |
| were updated to work correctly with modules imported from zipfiles or |
| via other PEP 302 __loader__ objects. |
| |
| - Patch #1467770: Reduce usage of subprocess._active to processes which |
| the application hasn't waited on. |
| |
| - Patch #1462222: Fix Tix.Grid. |
| |
| - Fix exception when doing glob.glob('anything*/') |
| |
| - The pstats.Stats class accepts an optional stream keyword argument to |
| direct output to an alternate file-like object. |
| |
| Build |
| ----- |
| |
| - The Makefile now has a reindent target, which runs reindent.py on |
| the library. |
| |
| - Patch #1470875: Building Python with MS Free Compiler |
| |
| - Patch #1161914: Add a python-config script. |
| |
| - Patch #1324762:Remove ccpython.cc; replace --with-cxx with |
| --with-cxx-main. Link with C++ compiler only if --with-cxx-main was |
| specified. (Can be overridden by explicitly setting LINKCC.) Decouple |
| CXX from --with-cxx-main, see description in README. |
| |
| - Patch #1429775: Link extension modules with the shared libpython. |
| |
| - Fixed a libffi build problem on MIPS systems. |
| |
| - ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV`` |
| now accept formats "%u" for unsigned ints, "%lu" for unsigned longs, |
| and "%zu" for unsigned integers of type ``size_t``. |
| |
| Tests |
| ----- |
| |
| - test_contextlib now checks contextlib.nested can cope with exceptions |
| being raised and caught inside exit handlers. |
| |
| - test_cmd_line now checks operation of the -m and -c command switches |
| |
| - The test_contextlib test in 2.5a1 wasn't actually run unless you ran |
| it separately and by hand. It also wasn't cleaning up its changes to |
| the current Decimal context. |
| |
| - regrtest.py now has a -M option to run tests that test the new limits of |
| containers, on 64-bit architectures. Running these tests is only sensible |
| on 64-bit machines with more than two gigabytes of memory. The argument |
| passed is the maximum amount of memory for the tests to use. |
| |
| Tools |
| ----- |
| |
| - Added the Python benchmark suite pybench to the Tools/ directory; |
| contributed by Marc-Andre Lemburg. |
| |
| Documentation |
| ------------- |
| |
| - Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``. |
| |
| - PEP 343: Added Context Types section to the library reference |
| and attempted to bring other PEP 343 related documentation into |
| line with the implementation and/or python-dev discussions. |
| |
| - Bug #1337990: clarified that ``doctest`` does not support examples |
| requiring both expected output and an exception. |
| |
| |
| What's New in Python 2.5 alpha 1? |
| ================================= |
| |
| *Release date: 05-APR-2006* |
| |
| Core and builtins |
| ----------------- |
| |
| - PEP 338: -m command line switch now delegates to runpy.run_module |
| allowing it to support modules in packages and zipfiles |
| |
| - On Windows, .DLL is not an accepted file name extension for |
| extension modules anymore; extensions are only found if they |
| end in .PYD. |
| |
| - Bug #1421664: sys.stderr.encoding is now set to the same value as |
| sys.stdout.encoding. |
| |
| - __import__ accepts keyword arguments. |
| |
| - Patch #1460496: round() now accepts keyword arguments. |
| |
| - Fixed bug #1459029 - unicode reprs were double-escaped. |
| |
| - Patch #1396919: The system scope threads are reenabled on FreeBSD |
| 5.4 and later versions. |
| |
| - Bug #1115379: Compiling a Unicode string with an encoding declaration |
| now gives a SyntaxError. |
| |
| - Previously, Python code had no easy way to access the contents of a |
| cell object. Now, a ``cell_contents`` attribute has been added |
| (closes patch #1170323). |
| |
| - Patch #1123430: Python's small-object allocator now returns an arena to |
| the system ``free()`` when all memory within an arena becomes unused |
| again. Prior to Python 2.5, arenas (256KB chunks of memory) were never |
| freed. Some applications will see a drop in virtual memory size now, |
| especially long-running applications that, from time to time, temporarily |
| use a large number of small objects. Note that when Python returns an |
| arena to the platform C's ``free()``, there's no guarantee that the |
| platform C library will in turn return that memory to the operating system. |
| The effect of the patch is to stop making that impossible, and in tests it |
| appears to be effective at least on Microsoft C and gcc-based systems. |
| Thanks to Evan Jones for hard work and patience. |
| |
| - Patch #1434038: property() now uses the getter's docstring if there is |
| no "doc" argument given. This makes it possible to legitimately use |
| property() as a decorator to produce a read-only property. |
| |
| - PEP 357, patch 1436368: add an __index__ method to int/long and a matching |
| nb_index slot to the PyNumberMethods struct. The slot is consulted instead |
| of requiring an int or long in slicing and a few other contexts, enabling |
| other objects (e.g. Numeric Python's integers) to be used as slice indices. |
| |
| - Fixed various bugs reported by Coverity's Prevent tool. |
| |
| - PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the |
| new exception base class, BaseException, which has a new message attribute. |
| KeyboardInterrupt and SystemExit to directly inherit from BaseException now. |
| Raising a string exception now raises a DeprecationWarning. |
| |
| - Patch #1438387, PEP 328: relative and absolute imports. Imports can now be |
| explicitly relative, using 'from .module import name' to mean 'from the same |
| package as this module is in. Imports without dots still default to the |
| old relative-then-absolute, unless 'from __future__ import |
| absolute_import' is used. |
| |
| - Properly check if 'warnings' raises an exception (usually when a filter set |
| to "error" is triggered) when raising a warning for raising string |
| exceptions. |
| |
| - CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default. |
| The name was removed from Include/code.h. |
| |
| - PEP 308: conditional expressions were added: (x if cond else y). |
| |
| - Patch 1433928: |
| - The copy module now "copies" function objects (as atomic objects). |
| - dict.__getitem__ now looks for a __missing__ hook before raising |
| KeyError. |
| |
| - PEP 343: with statement implemented. Needs ``from __future__ import |
| with_statement``. Use of 'with' as a variable will generate a warning. |
| Use of 'as' as a variable will also generate a warning (unless it's |
| part of an import statement). |
| The following objects have __context__ methods: |
| - The built-in file type. |
| - The thread.LockType type. |
| - The following types defined by the threading module: |
| Lock, RLock, Condition, Semaphore, BoundedSemaphore. |
| - The decimal.Context class. |
| |
| - Fix the encodings package codec search function to only search |
| inside its own package. Fixes problem reported in patch #1433198. |
| |
| Note: Codec packages should implement and register their own |
| codec search function. PEP 100 has the details. |
| |
| - PEP 353: Using ``Py_ssize_t`` as the index type. |
| |
| - ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging |
| info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353) |
| now allow Python to make use of memory blocks exceeding 2**32 bytes for |
| some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited |
| to 4-byte allocations before. |
| |
| - Patch #1400181, fix unicode string formatting to not use the locale. |
| This is how string objects work. u'%f' could use , instead of . |
| for the decimal point. Now both strings and unicode always use periods. |
| |
| - Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8. |
| configure would break checking curses.h. |
| |
| - Bug #959576: The pwd module is now builtin. This allows Python to be |
| built on UNIX platforms without $HOME set. |
| |
| - Bug #1072182, fix some potential problems if characters are signed. |
| |
| - Bug #889500, fix line number on SyntaxWarning for global declarations. |
| |
| - Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter. |
| |
| - Support for converting hex strings to floats no longer works. |
| This was not portable. float('0x3') now raises a ValueError. |
| |
| - Patch #1382163: Expose Subversion revision number to Python. New C API |
| function Py_GetBuildNumber(). New attribute sys.subversion. Build number |
| is now displayed in interactive prompt banner. |
| |
| - Implementation of PEP 341 - Unification of try/except and try/finally. |
| "except" clauses can now be written together with a "finally" clause in |
| one try statement instead of two nested ones. Patch #1355913. |
| |
| - Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec |
| now encodes backslash correctly. |
| |
| - Patch #1350409: Work around signal handling bug in Visual Studio 2005. |
| |
| - Bug #1281408: Py_BuildValue now works correctly even with unsigned longs |
| and long longs. |
| |
| - SF Bug #1350188, "setdlopenflags" leads to crash upon "import" |
| It was possible for dlerror() to return a NULL pointer, so |
| it will now use a default error message in this case. |
| |
| - Replaced most Unicode charmap codecs with new ones using the |
| new Unicode translate string feature in the builtin charmap |
| codec; the codecs were created from the mapping tables available |
| at ftp.unicode.org and contain a few updates (e.g. the Mac OS |
| encodings now include a mapping for the Apple logo) |
| |
| - Added a few more codecs for Mac OS encodings |
| |
| - Sped up some Unicode operations. |
| |
| - A new AST parser implementation was completed. The abstract |
| syntax tree is available for read-only (non-compile) access |
| to Python code; an _ast module was added. |
| |
| - SF bug #1167751: fix incorrect code being produced for generator expressions. |
| The following code now raises a SyntaxError: foo(a = i for i in range(10)) |
| |
| - SF Bug #976608: fix SystemError when mtime of an imported file is -1. |
| |
| - SF Bug #887946: fix segfault when redirecting stdin from a directory. |
| Provide a warning when a directory is passed on the command line. |
| |
| - Fix segfault with invalid coding. |
| |
| - SF bug #772896: unknown encoding results in MemoryError. |
| |
| - All iterators now have a Boolean value of True. Formerly, some iterators |
| supported a __len__() method which evaluated to False when the iterator |
| was empty. |
| |
| - On 64-bit platforms, when __len__() returns a value that cannot be |
| represented as a C int, raise OverflowError. |
| |
| - test__locale is skipped on OS X < 10.4 (only partial locale support is |
| present). |
| |
| - SF bug #893549: parsing keyword arguments was broken with a few format |
| codes. |
| |
| - Changes donated by Elemental Security to make it work on AIX 5.3 |
| with IBM's 64-bit compiler (SF patch #1284289). This also closes SF |
| bug #105470: test_pwd fails on 64bit system (Opteron). |
| |
| - Changes donated by Elemental Security to make it work on HP-UX 11 on |
| Itanium2 with HP's 64-bit compiler (SF patch #1225212). |
| |
| - Disallow keyword arguments for type constructors that don't use them |
| (fixes bug #1119418). |
| |
| - Forward UnicodeDecodeError into SyntaxError for source encoding errors. |
| |
| - SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for |
| exceptions that cause a function to exit. |
| |
| - The implementation of set() and frozenset() was revised to use its |
| own internal data structure. Memory consumption is reduced by 1/3 |
| and there are modest speed-ups as well. The API is unchanged. |
| |
| - SF bug #1238681: freed pointer is used in longobject.c:long_pow(). |
| |
| - SF bug #1229429: PyObject_CallMethod failed to decrement some |
| reference counts in some error exit cases. |
| |
| - SF bug #1185883: Python's small-object memory allocator took over |
| a block managed by the platform C library whenever a realloc specified |
| a small new size. However, there's no portable way to know then how |
| much of the address space following the pointer is valid, so there's no |
| portable way to copy data from the C-managed block into Python's |
| small-object space without risking a memory fault. Python's small-object |
| realloc now leaves such blocks under the control of the platform C |
| realloc. |
| |
| - SF bug #1232517: An overflow error was not detected properly when |
| attempting to convert a large float to an int in os.utime(). |
| |
| - SF bug #1224347: hex longs now print with lowercase letters just |
| like their int counterparts. |
| |
| - SF bug #1163563: the original fix for bug #1010677 ("thread Module |
| Breaks PyGILState_Ensure()") broke badly in the case of multiple |
| interpreter states; back out that fix and do a better job (see |
| http://mail.python.org/pipermail/python-dev/2005-June/054258.html |
| for a longer write-up of the problem). |
| |
| - SF patch #1180995: marshal now uses a binary format by default when |
| serializing floats. |
| |
| - SF patch #1181301: on platforms that appear to use IEEE 754 floats, |
| the routines that promise to produce IEEE 754 binary representations |
| of floats now simply copy bytes around. |
| |
| - bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP |
| 278. |
| |
| - patch #1109424: int, long, float, complex, and unicode now check for the |
| proper magic slot for type conversions when subclassed. Previously the |
| magic slot was ignored during conversion. Semantics now match the way |
| subclasses of str always behaved. int/long/float, conversion of an instance |
| to the base class has been moved to the proper nb_* magic slot and out of |
| PyNumber_*(). |
| Thanks Walter D�rwald. |
| |
| - Descriptors defined in C with a PyGetSetDef structure, where the setter is |
| NULL, now raise an AttributeError when attempting to set or delete the |
| attribute. Previously a TypeError was raised, but this was inconsistent |
| with the equivalent pure-Python implementation. |
| |
| - It is now safe to call PyGILState_Release() before |
| PyEval_InitThreads() (note that if there is reason to believe there |
| are multiple threads around you still must call PyEval_InitThreads() |
| before using the Python API; this fix is for extension modules that |
| have no way of knowing if Python is multi-threaded yet). |
| |
| - Typing Ctrl-C whilst raw_input() was waiting in a build with threads |
| disabled caused a crash. |
| |
| - Bug #1165306: instancemethod_new allowed the creation of a method |
| with im_class == im_self == NULL, which caused a crash when called. |
| |
| - Move exception finalisation later in the shutdown process - this |
| fixes the crash seen in bug #1165761 |
| |
| - Added two new builtins, any() and all(). |
| |
| - Defining a class with empty parentheses is now allowed |
| (e.g., ``class C(): pass`` is no longer a syntax error). |
| Patch #1176012 added support to the 'parser' module and 'compiler' package |
| (thanks to logistix for that added support). |
| |
| - Patch #1115086: Support PY_LONGLONG in structmember. |
| |
| - Bug #1155938: new style classes did not check that __init__() was |
| returning None. |
| |
| - Patch #802188: Report characters after line continuation character |
| ('\') with a specific error message. |
| |
| - Bug #723201: Raise a TypeError for passing bad objects to 'L' format. |
| |
| - Bug #1124295: the __name__ attribute of file objects was |
| inadvertently made inaccessible in restricted mode. |
| |
| - Bug #1074011: closing sys.std{out,err} now causes a flush() and |
| an ferror() call. |
| |
| - min() and max() now support key= arguments with the same meaning as in |
| list.sort(). |
| |
| - The peephole optimizer now performs simple constant folding in expressions: |
| (2+3) --> (5). |
| |
| - set and frozenset objects can now be marshalled. SF #1098985. |
| |
| - Bug #1077106: Poor argument checking could cause memory corruption |
| in calls to os.read(). |
| |
| - The parser did not complain about future statements in illegal |
| positions. It once again reports a syntax error if a future |
| statement occurs after anything other than a doc string. |
| |
| - Change the %s format specifier for str objects so that it returns a |
| unicode instance if the argument is not an instance of basestring and |
| calling __str__ on the argument returns a unicode instance. |
| |
| - Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the |
| current thread state when the auto-GIL-state machinery knows about |
| it (since the thread state is being deleted, continuing to remember it |
| can't help, but can hurt if another thread happens to get created with |
| the same thread id). |
| |
| Extension Modules |
| ----------------- |
| |
| - Patch #1380952: fix SSL objects timing out on consecutive read()s |

| lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse, |
| util, whatsound, whrandom, zmod |
| |
| - The following modules were removed: regsub, reconvert, regex, regex_syntax. |
| |

| than the system default domain. |
| |
| - Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps |

| st_birthtime for FreeBSD. |
| |

| were set in a different thread than that which called readline. |
| |
| - collections.deque objects now support a remove() method. |
| |

| create datetime object using a string and format. |
| |
| - Patch #1117961: Replace the MD5 implementation from RSA Data Security Inc |

| |
| Library |
| ------- |
| |
| - Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have |
| been renamed to have only a single underscore prefix. This was done to |
| make subclassing easier. |
| |
| - PEP 338: new module runpy defines a run_module function to support |
| executing modules which provide access to source code or a code object |
| via the PEP 302 import mechanisms. |
| |
| - The email module's parsedate_tz function now sets the daylight savings |
| flag to -1 (unknown) since it can't tell from the date whether it should |
| be set. |
| |
| - Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results |
| now sport attributes that provide access to the parts of the result. |
| |
| - Patch #1462498: sgmllib now handles entity and character references |
| in attribute values. |
| |
| - Added the sqlite3 package. This is based on pysqlite2.1.3, and provides |
| a DB-API interface in the standard library. You'll need sqlite 3.0.8 or |
| later to build this - if you have an earlier version, the C extension |
| module will not be built. |
| |
| - Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts |
| aren't officially supported here, and trying to use them will probably |
| raise an exception some day. But dicts have been allowed, and "mostly |
| worked", so support for them won't go away without warning. |
| |
| - Bug #1445068: getpass.getpass() can now be given an explicit stream |
| argument to specify where to write the prompt. |
| |
| - Patch #1462313, bug #1443328: the pickle modules now can handle classes |
| that have __private names in their __slots__. |
| |

| |
| - patch #1457316: "setup.py upload" now supports --identity to select the |
| key to be used for signing the uploaded code. |
| |
| - Queue.Queue objects now support .task_done() and .join() methods |
| to make it easier to monitor when daemon threads have completed |
| processing all enqueued tasks. Patch #1455676. |
| |
| - popen2.Popen objects now preserve the command in a .cmd attribute. |
| |
| - Added the ctypes ffi package. |
| |
| - email 4.0 package now integrated. This is largely the same as the email 3.0 |
| package that was included in Python 2.3, except that PEP 8 module names are |
| now used (e.g. mail.message instead of email.Message). The MIME classes |
| have been moved to a subpackage (e.g. email.mime.text instead of |
| email.MIMEText). The old names are still supported for now. Several |
| deprecated Message methods have been removed and lots of bugs have been |
| fixed. More details can be found in the email package documentation. |
| |
| - Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object |
| (a subclass of tuple) that provides incremental decoders and encoders |
| (a way to use stateful codecs without the stream API). Python functions |
| codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well |
| as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder() |
| have been added. |
| |
| - Patch #1359365: Calling next() on a closed StringIO.String object raises |
| a ValueError instead of a StopIteration now (like file and cString.String do). |
| cStringIO.StringIO.isatty() will raise a ValueError now if close() has been |
| called before (like file and StringIO.StringIO do). |
| |
| - A regrtest option -w was added to re-run failed tests in verbose mode. |
| |
| - Patch #1446372: quit and exit can now be called from the interactive |
| interpreter to exit. |
| |
| - The function get_count() has been added to the gc module, and gc.collect() |
| grew an optional 'generation' argument. |
| |
| - A library msilib to generate Windows Installer files, and a distutils |
| command bdist_msi have been added. |
| |
| - PEP 343: new module contextlib.py defines decorator @contextmanager |
| and helpful context managers nested() and closing(). |
| |
| - The compiler package now supports future imports after the module docstring. |
| |
| - Bug #1413790: zipfile now sanitizes absolute archive names that are |
| not allowed by the specs. |
| |
| - Patch #1215184: FileInput now can be given an opening hook which can |
| be used to control how files are opened. |
| |
| - Patch #1212287: fileinput.input() now has a mode parameter for |
| specifying the file mode input files should be opened with. |
| |
| - Patch #1215184: fileinput now has a fileno() function for getting the |
| current file number. |
| |
| - Patch #1349274: gettext.install() now optionally installs additional |
| translation functions other than _() in the builtin namespace. |
| |

| in pydoc. |
| |
| - Patch #1412872: zipfile now sets the creator system to 3 (Unix) |
| unless the system is Win32. |
| |
| - Patch #1349118: urllib now supports user:pass@ style proxy |
| specifications, raises IOErrors when proxies for unsupported protocols |
| are defined, and uses the https proxy on https redirections. |
| |
| - Bug #902075: urllib2 now supports 'host:port' style proxy specifications. |
| |
| - Bug #1407902: Add support for sftp:// URIs to urlparse. |
| |
| - Bug #1371247: Update Windows locale identifiers in locale.py. |
| |
| - Bug #1394565: SimpleHTTPServer now doesn't choke on query parameters |
| any more. |
| |
| - Bug #1403410: The warnings module now doesn't get confused |
| when it can't find out the module name it generates a warning for. |
| |
| - Patch #1177307: Added a new codec utf_8_sig for UTF-8 with a BOM signature. |
| |
| - Patch #1157027: cookielib mishandles RFC 2109 cookies in Netscape mode |
| |
| - Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise |
| LoadError as documented, instead of IOError. For compatibility, |
| LoadError subclasses IOError. |
| |
| - Added the hashlib module. It provides secure hash functions for MD5 and |
| SHA1, 224, 256, 384, and 512. Note that recent developments make the |
| historic MD5 and SHA1 unsuitable for cryptographic-strength applications. |
| In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html> |
| Ronald L. Rivest offered this advice for Python: |
| |
| "The consensus of researchers in this area (at least as |
| expressed at the NIST Hash Function Workshop 10/31/05), |
| is that SHA-256 is a good choice for the time being, but |
| that research should continue, and other alternatives may |
| arise from this research. The larger SHA's also seem OK." |
| |
| - Added a subset of Fredrik Lundh's ElementTree package. Available |
| modules are xml.etree.ElementTree, xml.etree.ElementPath, and |
| xml.etree.ElementInclude, from ElementTree 1.2.6. |

| |
| - Patch #827386: Support absolute source paths in msvccompiler.py. |

| Tkdnd. |
| |
| - Bug #1015140: disambiguated the term "article id" in nntplib docs and |
| docstrings to either "article number" or "message id". |
| |

| it can be missing in embedded interpreters |
| |
| - Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib. |
| |
| - Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via |
| error messages. |
| |
| - Bug #1108948: Cookie.py produced invalid JavaScript code. |
| |
| - The tokenize module now detects and reports indentation errors. |
| Bug #1224621. |
| |
| - The tokenize module has a new untokenize() function to support a full |
| roundtrip from lexed tokens back to Python source code. In addition, |

| files to PyPI. |
| |
| - distutils.commands.register now encodes the data as UTF-8 before posting |
| them to PyPI. |
| |

| instead of raising a TypeError when interacting with other types. This |
| allows other classes to implement __radd__ style methods and have them |
| work as expected. |
| |
| - Bug #1163325: Decimal infinities failed to hash. Attempting to |
| hash a NaN raised an InvalidOperation instead of a TypeError. |

| disables recursive traversal through instance attributes, which can |
| be exploited in various ways. |
| |
| - Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec |
| flags on the HTTP listening socket. |
| |
| - Bug #792570: SimpleXMLRPCServer had problems if the request grew too large. |
| Fixed by reading the HTTP body in chunks instead of one big socket.read(). |
| |

| constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler. |
| |

| - Bug #1103844: fix distutils.install.dump_dirs() with negated options. |
| |
| - os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience. |
| |
| - Enhancements to the csv module: |
| |
| + Dialects are now validated by the underlying C code, better |
| reflecting its capabilities, and improving its compliance with |
| PEP 305. |
| + Dialect parameter parsing has been re-implemented to improve error |
| reporting. |
| + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305 |
| dictates. |
| + the parser now removes the escapechar prefix from escaped characters. |
| + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric |
| types, rather than any object that can be represented as a numeric. |
| + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields |
| to floats. |
| + reader now allows \r characters to be quoted (previously it only allowed |
| \n to be quoted). |
| + writer doublequote handling improved. |
| + Dialect classes passed to the module are no longer instantiated by |
| the module before being parsed (the former validation scheme required |
| this, but the mechanism was unreliable). |
| + The dialect registry now contains instances of the internal |
| C-coded dialect type, rather than references to python objects. |
| + the internal c-coded dialect type is now immutable. |
| + register_dialect now accepts the same keyword dialect specifications |
| as the reader and writer, allowing the user to register dialects |
| without first creating a dialect class. |
| + a configurable limit to the size of parsed fields has been added - |
| previously, an unmatched quote character could result in the entire |
| file being read into the field buffer before an error was reported. |
| + A new module method csv.field_size_limit() has been added that sets |
| the parser field size limit (returning the former limit). The initial |
| limit is 128kB. |
| + A line_num attribute has been added to the reader object, which tracks |
| the number of lines read from the source iterator. This is not |
| the same as the number of records returned, as records can span |
| multiple lines. |
| + reader and writer objects were not being registered with the cyclic-GC. |
| This has been fixed. |
| |
| - _DummyThread objects in the threading module now delete self.__block that is |
| inherited from _Thread since it uses up a lock allocated by 'thread'. The |
| lock primitives tend to be limited in number and thus should not be wasted on |
| a _DummyThread object. Fixes bug #1089632. |
| |
| - The imghdr module now detects Exif files. |
| |
| - StringIO.truncate() now correctly adjusts the size attribute. |
| (Bug #951915). |
| |
| - locale.py now uses an updated locale alias table (built using |
| Tools/i18n/makelocalealias.py, a tool to parse the X11 locale |
| alias file); the encoding lookup was enhanced to use Python's |
| encoding alias table. |
| |
| - moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache. |
| |
| - the pickle module no longer accepts the deprecated None option in the |
| args tuple returned by __reduce__(). |
| |
| - optparse now optionally imports gettext. This allows its use in setup.py. |
| |
| - the pickle module no longer uses the deprecated bin parameter. |
| |
| - the shelve module no longer uses the deprecated binary parameter. |
| |
| - the pstats module no longer uses the deprecated ignore() method. |
| |
| - the filecmp module no longer uses the deprecated use_statcache argument. |
| |
| - unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully |
| extended or overridden by subclasses. Formerly, the subclassed method would |
| be ignored by the rest of the module. (Bug #1078905). |
| |
| - heapq.nsmallest() and heapq.nlargest() now support key= arguments with |
| the same meaning as in list.sort(). |
| |
| - Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only |
| once when a size argument is given. This prevents a buffer overflow in the |
| tokenizer with very long source lines. |
| |
| - Bug #1083110: ``zlib.decompress.flush()`` would segfault if called |
| immediately after creating the object, without any intervening |
| ``.decompress()`` calls. |
| |
| - The reconvert.quote function can now emit triple-quoted strings. The |
| reconvert module now has some simple documentation. |
| |
| - ``UserString.MutableString`` now supports negative indices in |
| ``__setitem__`` and ``__delitem__`` |
| |
| - Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05") |
| correctly. |
| |
| - Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by |
| ``codecs.StreamReader.readline()`` has a trailing "\r", read one more |
| character even if the user has passed a size parameter to get a proper |
| line ending. Remove the special handling of a "\r\n" that has been split |
| between two lines. |
| |
| - Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain |
| about illegal code points. The codec now supports PEP 293 style error |
| handlers. |
| |
| - Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads |
| from the input stream, so that the output is a byte string in the correct |
| encoding instead of a unicode string. |
| |
| - Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than |
| considering it exactly like a '*'. |
| |
| - Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to |
| ``encodings.aliases``. |
| |
| - ` uu.encode()`` and ``uu.decode()`` now support unicode filenames. |
| |
| - Patch #1413711: Certain patterns of differences were making difflib |
| touch the recursion limit. |
| |
| - Bug #947906: An object oriented interface has been added to the calendar |
| module. It's possible to generate HTML calendar now and the module can be |
| called as a script (e.g. via ``python -mcalendar``). Localized month and |
| weekday names can be ouput (even if an exotic encoding is used) using |
| special classes that use unicode. |
| |
| Build |
| ----- |
| |
| - Fix test_float, test_long, and test_struct failures on Tru64 with gcc |
| by using -mieee gcc option. |
| |
| - Patch #1432345: Make python compile on DragonFly. |
| |
| - Build support for Win64-AMD64 was added. |
| |
| - Patch #1428494: Prefer linking against ncursesw over ncurses library. |
| |
| - Patch #881820: look for openpty and forkpty also in libbsd. |
| |
| - The sources of zlib are now part of the Python distribution (zlib 1.2.3). |
| The zlib module is now builtin on Windows. |
| |
| - Use -xcode=pic32 for CCSHARED on Solaris with SunPro. |
| |
| - Bug #1189330: configure did not correctly determine the necessary |
| value of LINKCC if python was built with GCC 4.0. |
| |
| - Upgrade Windows build to zlib 1.2.3 which eliminates a potential security |
| vulnerability in zlib 1.2.1 and 1.2.2. |
| |
| - EXTRA_CFLAGS has been introduced as an environment variable to hold compiler |
| flags that change binary compatibility. Changes were also made to |
| distutils.sysconfig to also use the environment variable when used during |
| compilation of the interpreter and of C extensions through distutils. |
| |
| - SF patch 1171735: Darwin 8's headers are anal about POSIX compliance, |
| and linking has changed (prebinding is now deprecated, and libcc_dynamic |
| no longer exists). This configure patch makes things right. |
| |
| - Bug #1158607: Build with --disable-unicode again. |
| |
| - spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is |
| defined. Discovered as a result of not being able to build on OS X. |
| |
| - setup.py now uses the directories specified in LDFLAGS using the -L option |
| and in CPPFLAGS using the -I option for adding library and include |
| directories, respectively, for compiling extension modules against. This has |
| led to the core being compiled using the values in CPPFLAGS. It also removes |
| the need for the special-casing of both DarwinPorts and Fink for darwin since |
| the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink, |
| ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for |
| Fink, ``-I/opt/local/include`` for DarwinPorts). |
| |
| - Test in configure.in that checks for tzset no longer dependent on tm->tm_zone |
| to exist in the struct (not required by either ISO C nor the UNIX 2 spec). |
| Tests for sanity in tzname when HAVE_TZNAME defined were also defined. |
| Closes bug #1096244. Thanks Gregory Bond. |
| |
| C API |
| ----- |
| |
| - ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to |
| ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory |
| is obtained via the ``PyObject_`` family, it must be released via the |
| ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has |
| always been officially true, but when Python's small-object allocator was |
| introduced, an attempt was made to cater to a few extension modules |
| discovered at the time that obtained memory via ``PyObject_New`` but |
| released it via ``PyMem_DEL``. It's years later, and if such code still |
| exists it will fail now (probably with segfaults, but calling wrong |
| low-level memory management functions can yield many symptoms). |
| |
| - Added a C API for set and frozenset objects. |
| |
| - Removed PyRange_New(). |
| |
| - Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the |
| mapping argument now. This string is used as a mapping table. Byte values |
| greater than the length of the string and 0xFFFE are treated as undefined |
| mappings. |
| |
| |
| Tests |
| ----- |
| |
| - In test_os, st_?time is now truncated before comparing it with ST_?TIME. |
| |
| - Patch #1276356: New resource "urlfetch" is implemented. This enables |
| even impatient people to run tests that require remote files. |
| |
| |

| Mac OS 9 and change to reflect the state for OS X. |
| Closes patch #1095802. Thanks Jack Jansen. |
| |
| Mac |

| |
| |
| New platforms |
| ------------- |
| |
| - FreeBSD 7 support is added. |
| |
| |
| Tools/Demos |
| ----------- |
| |
| - Created Misc/Vim/vim_syntax.py to auto-generate a python.vim file in that |
| directory for syntax highlighting in Vim. Vim directory was added and placed |
| vimrc to it (was previous up a level). |
| |
| - Added two new files to Tools/scripts: pysource.py, which recursively |
| finds Python source files, and findnocoding.py, which finds Python |
| source files that need an encoding declaration. |
| Patch #784089, credits to Oleg Broytmann. |
| |
| - Bug #1072853: pindent.py used an uninitialized variable. |
| |
| - Patch #1177597: Correct Complex.__init__. |
| |
| - Fixed a display glitch in Pynche, which could cause the right arrow to |
| wiggle over by a pixel. |
