| What's New in Python 2.6 alpha 3? |
| ================================= |
| |
| *Release date: XX-XXX-2008* |
| |
| Core and builtins |
| ----------------- |
| |
| - Patch #2617: Reserved -J and -X arguments for Jython, IronPython and other |
| implementations of Python. |
| |
| Extensions Modules |
| ------------------ |
| |
| - 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. |
| |
| Library |
| ------- |
| |
| - 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 #2544: On HP-UX systems, use 'gcc -shared' for linking when |
| gcc is used as compiler. |
| |
| 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. |
| |
| |
| What's New in Python 2.6 alpha 2? |
| ================================= |
| |
| *Release date: 02-Apr-2008* |
| |
| Core and builtins |
| ----------------- |

| threading.currentThread(). |
| |
| - Patch #1442: properly report exceptions when the PYTHONSTARTUP file |
| cannot be executed. |
| |
| - The compilation of a class nested in another class used to leak one |
| reference on the outer class name. |
| |
| - Patch #1810: compile() can now compile _ast trees as returned by |
| compile(..., PyCF_ONLY_AST). |
| |

| |
| - 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 #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 |

| |
| - 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. |
| |
| - Issue #2460: Make Ellipsis object copyable. |
| |
| - Issue #1681432: Add triangular distribution to the random module |

| 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. |
| |
| - 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 |

| 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. |
| |
| Tests |
| ----- |
| |
| - test_nis no longer fails when test.test_support.verbose is true and NIS is |
| not set up on the testing machine. |
| |
| - Output comparison tests are no longer supported. |

| |
| - GHOP 234: Convert test_extcall to doctest. |
| |
| - GHOP 290: Convert test_dbm and test_dummy_threading to unittest. |
| |
| - GHOP 293: Convert test_strftime, test_getargs, and test_pep247 to unittest. |
| |

| |
| - GHOP 238: Convert test_tokenize to use doctest. |
| |
| - GHOP 237: Rewrite test_thread using unittest. |
| |
| - Patch #2232: os.tmpfile might fail on Windows if the user has no |
| permission to create files in the root directory. |
| |
| Build |
| ----- |
| |
| - 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 |
| PyParser_ParseStringFlagsFilenameEx() |
| |
| What's New in Python 2.6 alpha 1? |
| ================================= |
| |
| *Release date: 29-Feb-2008* |
| |
| Core and builtins |
| ----------------- |
| |
| - Issue #2051: pyc and pyo files are no longer created with permission |
| 644. The mode is now inherited from the py file. |
| |
| - Issue #2067: file.__exit__() now calls subclasses' close() method. |
| |
| - Patch #1759: Backport of PEP 3129 class decorators. |
| |
| - Issue #1881: An internal parser limit has been increased. Also see |
| issue 215555 for a discussion. |
| |
| - Added the future_builtins module, which contains hex() and oct(). |
| These are the PEP 3127 version of these functions, designed to be |
| compatible with the hex() and oct() builtins from Python 3.0. They |
| differ slightly in their output formats from the existing, unchanged |
| Python 2.6 builtins. The expected usage of the future_builtins |
| module is: |
| from future_builtins import hex, oct |
| |
| - Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit |
| exponents for exponents with absolute value < 100. Follows C99 |
| standard. This is a change on Windows, which would use 3 digits. |
| Also, added 'n' to the formats that PyOS_ascii_formatd understands, |
| so that any alterations it does to the resulting string will be |
| available in stringlib/formatter.h (for float.__format__). |
| |
| - Implemented PEP 3101, Advanced String Formatting. This adds a new |
| builtin format(); a format() method for str and unicode; a |
| __format__() method to object, str, unicode, int, long, float, and |
| datetime; the class string.Formatter; and the C API |
| PyObject_Format(). |
| |
| - Fixed several potential crashes, all caused by specially crafted __del__ |
| methods exploiting objects in temporarily inconsistent state. |
| |
| - Issue #2115: Important speedup in setting __slot__ attributes. Also |
| prevent a possible crash: an Abstract Base Class would try to access a slot |
| on a registered virtual subclass. |
| |
| - Fixed repr() and str() of complex numbers with infinity or nan as real or |
| imaginary part. |
| |
| - Clear all free lists during a gc.collect() of the highest generation in order |
| to allow pymalloc to free more arenas. Python may give back memory to the |
| OS earlier. |
| |
| - Issue #2045: Fix an infinite recursion triggered when printing a subclass of |
| collections.defaultdict, if its default_factory is set to a bound method. |
| |
| - Fixed a minor memory leak in dictobject.c. The content of the free |
| list was not freed on interpreter shutdown. |
| |
| - Limit free list of method and builtin 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. |
| |
| - Bug #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. |
| |
| - Bug #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() builtin 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. |
| |
| - Bug #1733488: Fix compilation of bufferobject.c on AIX. |
| |
| - Bug #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. |
| |
| - Bug #1303614: don't expose object's __dict__ when the dict is |
| inherited from a builtin base. |
| |
| - When __slots__ are set to a unicode string, make it work the same as |
| setting a plain string, ie don't expand to single letter identifiers. |
| |
| - Request #1191699: Slices can now be pickled. |
| |
| - Request #1193128: str.translate() now allows a None argument for |
| translations that only remove characters without re-mapping the |
| remaining characters. |
| |
| - Patch #1682205: a TypeError while unpacking an iterable is no longer |
| masked by a generic one with the message "unpack non-sequence". |
| |
| - Remove unused file Python/fmod.c. |
| |
| - Bug #1683368: The object.__init__() and object.__new__() methods are |
| now stricter in rejecting excess arguments. The only time when |
| either allows excess arguments is when it is not overridden and the |
| other one is. For backwards compatibility, when both are |
| overridden, it is a deprecation warning (for now; maybe a Py3k |
| warning later). Also, type.__init__() insists on the same signature |
| as supported by type.__new__(). |
| |
| - Patch #1675423: PyComplex_AsCComplex() now tries to convert an object |
| to complex using its __complex__() method before falling back to the |
| __float__() method. Therefore, the functions in the cmath module now |
| can operate on objects that define a __complex__() method. |
| |
| - Patch #1623563: allow __class__ assignment for classes with __slots__. |
| The old and the new class are still required to have the same slot names. |
| |
| - Patch #1642547: Fix an error/crash when encountering syntax errors in |
| complex if statements. |
| |
| - Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()`` |
| is called with an object that is faking its type. |
| |
| - Patch #1680015: Don't modify __slots__ tuple if it contains an unicode |
| name. |
| |
| - Patch #1444529: the builtin compile() now accepts keyword arguments. |
| |
| - Bug #1678647: write a newline after printing an exception in any |
| case, even when converting the value to a string failed. |
| |
| - The dir() function has been extended to call the __dir__() method on |
| its argument, if it exists. If not, it will work like before. This allows |
| customizing the output of dir() in the presence of a __getattr__(). |
| |
| - Patch #922167: Python no longer segfaults when faced with infinitely |
| self-recursive reload() calls (as reported by bug #742342). |
| |
| - Patch #1675981: remove unreachable code from ``type.__new__()`` method. |
| |
| - Patch #1491866: change the complex() constructor to allow parthensized |
| forms. This means complex(repr(x)) now works instead of raising a |
| ValueError. |
| |
| - Patch #703779: unset __file__ in __main__ after running a file. This |
| makes the filenames the warning module prints much more sensible when |
| a PYTHONSTARTUP file is used. |
| |
| - Variant of patch #697613: don't exit the interpreter on a SystemExit |
| exception if the -i command line option or PYTHONINSPECT environment |
| variable is given, but break into the interactive interpreter just like |
| on other exceptions or normal program exit. |
| |
| - Patch #1638879: don't accept strings with embedded NUL bytes in long(). |
| |
| - Bug #1674503: close the file opened by execfile() in an error condition. |
| |
| - Patch #1674228: when assigning a slice (old-style), check for the |
| sq_ass_slice instead of the sq_slice slot. |
| |
| - When printing an unraisable error, don't print exceptions. before the name. |
| This duplicates the behavior whening normally printing exceptions. |
| |
| - Bug #1653736: Properly discard third argument to slot_nb_inplace_power. |
| |
| - PEP 352: Raising a string exception now triggers a TypeError. Attempting to |
| catch a string exception raises DeprecationWarning. |
| |
| - Bug #1377858: Fix the segfaulting of the interpreter when an object created |
| a weakref on itself during a __del__ call for new-style classes (classic |
| classes still have the bug). |
| |
| - Bug #1579370: Make PyTraceBack_Here use the current thread, not the |
| frame's thread state. |
| |
| - patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py |
| |
| - Prevent seg fault on shutdown which could occur if an object |
| raised a warning. |
| |
| - Bug #1566280: Explicitly invoke threading._shutdown from Py_Main, |
| to avoid relying on atexit. |
| |
| - Bug #1590891: random.randrange don't return correct value for big number |
| |
| - Patch #1586791: Better exception messages for some operations on strings, |
| tuples and lists. |
| |
| - Bug #1067760: Deprecate passing floats to file.seek. |
| |
| - Bug #1591996: Correctly forward exception in instance_contains(). |
| |
| - Bug #1588287: fix invalid assertion for `1,2` in debug builds. |
| |
| - Bug #1576657: when setting a KeyError for a tuple key, make sure that |
| the tuple isn't used as the "exception arguments tuple". |
| |
| - Bug #1565514, SystemError not raised on too many nested blocks. |
| |
| - Bug #1576174: WindowsError now displays the windows error code |
| again, no longer the posix error code. |
| |
| - Patch #1549049: Support long values in structmember, issue warnings |
| if the assigned value for structmember fields gets truncated. |
| |
| - Update the peephole optimizer to remove more dead code (jumps after returns) |
| and inline unconditional jumps to returns. |
| |
| - Bug #1545497: when given an explicit base, int() did ignore NULs |
| embedded in the string to convert. |
| |
| - Bug #1569998: break inside a try statement (outside a loop) is now |
| recognized and rejected. |
| |
| - list.pop(x) accepts any object x following the __index__ protocol. |
| |
| - A number of places, including integer negation and absolute value, |
| were fixed to not rely on undefined behaviour of the C compiler |
| anymore. |
| |
| - Bug #1566800: make sure that EnvironmentError can be called with any |
| number of arguments, as was the case in Python 2.4. |
| |
| - Patch #1567691: super() and new.instancemethod() now don't accept |
| keyword arguments any more (previously they accepted them, but didn't |
| use them). |
| |
| - Fix a bug in the parser's future statement handling that led to "with" |
| not being recognized as a keyword after, e.g., this statement: |
| from __future__ import division, with_statement |
| |
| - Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)). |
| |
| - Fix %zd string formatting on Mac OS X so it prints negative numbers. |
| |
| - Allow exception instances to be directly sliced again. |
| |
| - Bug #1551432: Exceptions do not define an explicit __unicode__ method. This |
| allows calling unicode() on exceptions classes directly to succeed. |
| |
| - Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack. |
| Also make sure that every exception class has __module__ set to |
| 'exceptions'. |
| |
| - Bug #1550983: emit better error messages for erroneous relative |
| imports (if not in package and if beyond toplevel package). |
| |
| - Overflow checking code in integer division ran afoul of new gcc |
| optimizations. Changed to be more standard-conforming. |
| |
| - Patch #1542451: disallow continue anywhere under a finally. |
| |
| - Patch #1546288: fix seg fault in dict_equal due to ref counting bug. |
| |
| - The return tuple from str.rpartition(sep) is (tail, sep, head) where |
| head is the original string if sep was not found. |
| |
| - Bug #1520864: unpacking singleton tuples in list comprehensions and |
| generator expressions (x for x, in ... ) works again. Fixing this problem |
| required changing the .pyc magic number. This means that .pyc files |
| generated before 2.5c2 will be regenerated. |
| |
| - ``with`` and ``as`` are now keywords. |
| |
| - Bug #1664966: Fix crash in exec if Unicode filename can't be decoded. |
| |
| - Issue #1537: Changed GeneratorExit's base class from Exception to |
| BaseException. |
| |
| - Fix Issue #1703448: A joined thread could show up in the |
| threading.enumerate() list after the join() for a brief period until |
| it actually exited. |
| |

| When too many positional arguments are passed, also a TypeError is |
| raised instead of a ValueError. |
| |
| - Convert the internal ctypes array type cache to a WeakValueDict so |
| that array types do not live longer than needed. |
| |
| - Issue #1786: pdb should use its own stdin/stdout around an exec call |

| expected a tuple type of length six instead of time.struct_time object. |
| |

| internal floating point type to the sys module. |
| |
| - Issue 1429818: patch for trace and doctest modules so they play nicely |
| together. |
| |
| - doctest made a bad assumption that a package's __loader__.get_data() |
| method used universal newlines. |
| |
| - Issue #1705170: contextlib.contextmanager was still swallowing |
| StopIteration in some cases. This should no longer happen. |

| |
| - Bug #1734723: Fix repr.Repr() so it doesn't ignore the maxtuple attribute. |
| |
| - The urlopen function of urllib2 now has an optional timeout parameter (note |
| that it actually works with HTTP, HTTPS, FTP and FTPS connections). |
| |
| - In ftplib, the FTP.ntransfercmd method, when in passive mode, now uses |
| the socket.create_connection function, using the timeout 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. |
| |
| - Bug #1730389: Change time.strptime() to use ``\s+`` instead of ``\s*`` when |
| matching spaces in the specified format argument. |

| |
| - shlex.split() now has an optional "posix" parameter. |
| |

| - Fix bug in marshal where bad data would cause a segfault due to |
| lack of an infinite recursion check. |
| |
| - Removed plat-freebsd2 and plat-freebsd3 directories (and IN.py in |
| the directories). |

| the traceback inadvertently or maliciously closing the comment and |
| injecting HTML into the error page. |

| (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. |
| |
| - Bug #1290505: time.strptime's internal cache of locale information is now |
| properly recreated when the locale is changed. |

| |
| - Added a timeout parameter to the constructor of other protocols |

| 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 |
| and HTTPSConnection now accept an optional timeout). |
| |
| - Bug #978833: Revert r50844, as it broke _socketobject.dup. |
| |

| 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. |
| |
| - Patch #1339796: add a relpath() function to os.path. |
| |
| - Patch #1681153: the wave module now closes a file object it opened if |
| initialization failed. |
| |
| - Bug #767111: fix long-standing bug in urllib which caused an |
| AttributeError instead of an IOError when the server's response didn't |
| contain a valid HTTP status line. |
| |

| expanded in ntpath.expandvars(), also "~user" home directory references |
| are recognized and handled on Windows. |
| |
| - Patch #1429539: pdb now correctly initializes the __main__ module for |
| the debugged script, which means that imports from __main__ work |

| strings for the code to time and the setup code. Also added two |
| convenience functions for instantiating a Timer and calling its methods. |

| whitespace while wrapping. |
| |
| - Patch #1603688: ConfigParser.SafeConfigParser now checks values that |

| |
| - unittest now verifies more of its assumptions. In particular, TestCase |

| - 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 |

| bytes. |
| |
| - The implementation of UnicodeError objects has been simplified (start and end |
| attributes are now stored directly as Py_ssize_t members). |
| |
| - Issue829951: In the smtplib module, SMTP.starttls() now complies with |
| RFC 3207 and forgets any knowledge obtained from the server not obtained |
| from the TLS negotiation itself. Patch contributed by Bill Fenner. |
| |
| - Issue1339: 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 characters |

| - Make test_runpy reentrant by fixing _check_module to clear out any module |
| being tested. Was causing an error by __import__ doing a reload on the |
| second run and thus suppressing bytecode recreation. |
| |
| - 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. |
| |
| - Added test.test_support.TransientResource which is a context manager to |
| surround calls to resources that are not guaranteed to work even if |
| test.test_support.requires says that the resource should exist. |
| |
| - Added a test for slicing of an exception. |
| |
| - Added test.test_support.EnvironmentVarGuard. It's a class that provides a |
| context manager so that one can temporarily set or unset environment |
| variables. |
| |
| - Added some tests for modulefinder. |
| |
| - Converted test_imp to use unittest. |
| |
| - Fix bsddb test_basics.test06_Transactions to check the version |
| number properly. |
| |
| - test.test_support.catch_warning is a new context manager that can be 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. |
| |
| - Tools/18n/pygettext.py was added to the list of scripts installed by |
| Tools/scripts/setup.py (tracker item 642309). |
| |
| - Added IronPython and Jython support to pybench (part of which |
| was patch #1563844) |
| |
| - Made some minor changes to pybench output to allow the user |
| to see which Python version is running pybench |
| |
| - Added support for the new platform module feature |
| platform.python_implementation(); this will now be saved |
| in the benchmark pickle |
| |

| |
| 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 #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. |

| - 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. |
