| |
| - Issue #16455: On FreeBSD and Solaris, if the locale is C, the |
| ASCII/surrogateescape codec is now used, instead of the locale encoding, to |
| decode the command line arguments. This change fixes inconsistencies with |
| os.fsencode() and os.fsdecode() because these operating systems announces an |
| ASCII locale encoding, whereas the ISO-8859-1 encoding is used in practice. |
| |

| |
| - Issue #16306: Fix multiple error messages when unknown command line |
| parameters where passed to the interpreter. Patch by Hieu Nguyen. |

| - Issue #16290: A float return value from the __complex__ special method is no |
| longer accepted in the complex() constructor. |
| |
| - Issue #16416: On Mac OS X, operating system data are now always |
| encoded/decoded to/from UTF-8/surrogateescape, instead of the locale encoding |
| (which may be ASCII if no locale environment variable is set), to avoid |
| inconsistencies with os.fsencode() and os.fsdecode() functions which are |
| already using UTF-8/surrogateescape. |
| |
| - Issue #16453: Fix equality testing of dead weakref objects. |
| |
| - Issue #9535: Fix pending signals that have been received but not yet |
| handled by Python to not persist after os.fork() in the child process. |

| Patch by Serhiy Storchaka. |
| |
| - Issue #8401: assigning an int to a bytearray slice (e.g. b[3:4] = 5) now |
| raises an error. |
| |
| - Issue #7317: Display full tracebacks when an error occurs asynchronously. |
| Patch by Alon Horev with update by Alexey Kachayev. |
| |
| - Issue #16309: Make PYTHONPATH="" behavior the same as if PYTHONPATH |
| not set at all. |
| |
| - Issue #10189: Improve the error reporting of SyntaxErrors related to global |
| and nonlocal statements. |
| |
| - Issue #16086: PyTypeObject.tp_flags and PyType_Spec.flags are now unsigned |
| (unsigned long and unsigned int) to avoid an undefined behaviour with |
| Py_TPFLAGS_TYPE_SUBCLASS ((1 << 31). PyType_GetFlags() result type is |
| now unsigned too (unsigned long, instead of long). |
| |

| |
| Library |
| ------- |
| |
| - Issue #15882: Change `_decimal` to accept any coefficient tuple when |

| *Release date: 09-Sep-2012* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #13992: The trashcan mechanism is now thread-safe. This eliminates |

| method. |
| |
| - Issue #15785: Modify `window.get_wch()` API of the curses module: return a |
| character for most keys, and an integer for special keys, instead of always |
| returning an integer. So it is now possible to distinguish special keys like |
| keypad keys. |
| |
| - Issue #14223: Fix `window.addch()` of the curses module for special characters |
| like curses.ACS_HLINE: the Python function addch(int) and addch(bytes) is now |
| calling the C function waddch()/mvwaddch() (as it was done in Python 3.2), |
| instead of wadd_wch()/mvwadd_wch(). The Python function addch(str) is still |
| calling the C function wadd_wch()/mvwadd_wch() if the Python curses is linked |
| to libncursesw. |
| |
| Build |

| msg isn't a str. |
| |
| - Issue #2051: Source file permission bits are once again correctly copied to |

| first argument, rather than requiring a separate "fileobj" argument. |
| |
| - gzip.open() now accepts file objects as well as filenames. |
| |
| - Issue #14992: os.makedirs(path, exist_ok=True) would raise an OSError |

| Build |
| ----- |
| |
| - Issue #13590: Improve support for OS X Xcode 4: |
| * Try to avoid building Python or extension modules with problematic |
| llvm-gcc compiler. |
| * Since Xcode 4 removes ppc support, extension module builds now |
| check for ppc compiler support and automatically remove ppc and |
| ppc64 archs when not available. |
| * Since Xcode 4 no longer install SDKs in default locations, |
| extension module builds now revert to using installed headers |
| and libs if the SDK used to build the interpreter is not |
| available. |
| * Update ./configure to use better defaults for universal builds; |
| in particular, --enable-universalsdk=yes uses the Xcode default |
| SDK and --with-universal-archs now defaults to "intel" if ppc |
| not available. |
| |
| - Issue #14225: Fix Unicode support for curses (#12567) on OS X |
| |
| - Issue #14928: Fix importlib bootstrap issues by using a custom executable |

| What's New in Python 3.3.0 Alpha 1? |
| =================================== |
| |
| *Release date: 05-Mar-2012* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #14172: Fix reference leak when marshalling a buffer-like object |
| (other than a bytes object). |
| |
| - Issue #13521: dict.setdefault() now does only one lookup for the given key, |
| making it "atomic" for many purposes. Patch by Filip Gruszczyński. |
| |
| - PEP 409, Issue #6210: "raise X from None" is now supported as a means of |
| suppressing the display of the chained exception context. The chained |
| context still remains available as the __context__ attribute. |
| |
| - Issue #10181: New memoryview implementation fixes multiple ownership |
| and lifetime issues of dynamically allocated Py_buffer members (#9990) |
| as well as crashes (#8305, #7433). Many new features have been added |
| (See whatsnew/3.3), and the documentation has been updated extensively. |
| The ndarray test object from _testbuffer.c implements all aspects of |
| PEP-3118, so further development towards the complete implementation |
| of the PEP can proceed in a test-driven manner. |
| |
| Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review |
| and many ideas. |
| |
| - Issue #12834: Fix incorrect results of memoryview.tobytes() for |
| non-contiguous arrays. |
| |
| - Issue #5231: Introduce memoryview.cast() method that allows changing |
| format and shape without making a copy of the underlying memory. |
| |
| - Issue #14084: Fix a file descriptor leak when importing a module with a |
| bad encoding. |
| |
| - Upgrade Unicode data to Unicode 6.1. |
| |
| - Issue #14040: Remove rarely used file name suffixes for C extensions |
| (under POSIX mainly). |
| |
| - Issue #14051: Allow arbitrary attributes to be set of classmethod and |
| staticmethod. |
| |
| - Issue #13703: oCERT-2011-003: Randomize hashes of str and bytes to protect |
| against denial of service attacks due to hash collisions within the dict and |
| set types. Patch by David Malcolm, based on work by Victor Stinner. |
| |
| - Issue #13020: Fix a reference leak when allocating a structsequence object |
| fails. Patch by Suman Saha. |
| |
| - Issue #13908: Ready types returned from PyType_FromSpec. |
| |
| - Issue #11235: Fix OverflowError when trying to import a source file whose |
| modification time doesn't fit in a 32-bit timestamp. |
| |
| - Issue #12705: A SyntaxError exception is now raised when attempting to |
| compile multiple statements as a single interactive statement. |
| |
| - Fix the builtin module initialization code to store the init function for |
| future reinitialization. |
| |
| - Issue #8052: The posix subprocess module would take a long time closing |
| all possible file descriptors in the child process rather than just open |
| file descriptors. It now closes only the open fds if possible for the |
| default close_fds=True behavior. |
| |
| - Issue #13629: Renumber the tokens in token.h so that they match the indexes |
| into _PyParser_TokenNames. |
| |
| - Issue #13752: Add a casefold() method to str. |
| |
| - Issue #13761: Add a "flush" keyword argument to the print() function, |
| used to ensure flushing the output stream. |
| |
| - Issue #13645: pyc files now contain the size of the corresponding source |
| code, to avoid timestamp collisions (especially on filesystems with a low |
| timestamp resolution) when checking for freshness of the bytecode. |
| |
| - PEP 380, Issue #11682: Add "yield from <x>" to support easy delegation to |
| subgenerators (initial patch by Greg Ewing, integration into 3.3 by |
| Renaud Blanch, Ryan Kelly, Zbigniew Jędrzejewski-Szmek and Nick Coghlan) |
| |
| - Issue #13748: Raw bytes literals can now be written with the ``rb`` prefix |
| as well as ``br``. |
| |
| - Issue #12736: Use full unicode case mappings for upper, lower, and title case. |
| |
| - Issue #12760: Add a create mode to open(). Patch by David Townshend. |
| |

| objects. Initial patch by Matthias Troffaes. |
| |
| - Fix OSError.__init__ and OSError.__new__ so that each of them can be |
| overriden and take additional arguments (followup to issue #12555). |
| |
| - Fix the fix for issue #12149: it was incorrect, although it had the side |
| effect of appearing to resolve the issue. Thanks to Mark Shannon for |
| noticing. |
| |
| - Issue #13505: Pickle bytes objects in a way that is compatible with |
| Python 2 when using protocols <= 2. |
| |
| - Issue #11147: Fix an unused argument in _Py_ANNOTATE_MEMORY_ORDER. (Fix |
| given by Campbell Barton). |
| |
| - Issue #13503: Use a more efficient reduction format for bytearrays with |
| pickle protocol >= 3. The old reduction format is kept with older protocols |
| in order to allow unpickling under Python 2. Patch by Irmen de Jong. |
| |
| - Issue #7111: Python can now be run without a stdin, stdout or stderr |
| stream. It was already the case with Python 2. However, the corresponding |
| sys module entries are now set to None (instead of an unusable file object). |
| |
| - Issue #11849: Ensure that free()d memory arenas are really released |
| on POSIX systems supporting anonymous memory mappings. Patch by |
| Charles-François Natali. |
| |
| - Issue #13452: PyUnicode_EncodeDecimal() doesn't support error handlers |
| different than "strict" anymore. The caller was unable to compute the |
| size of the output buffer: it depends on the error handler. |
| |
| - PEP 3155 / issue #13448: Qualified name for classes and functions. |
| |
| - Issue #13436: Fix a bogus error message when an AST object was passed |

| object is hashable. |
| |
| - Issue #13338: Handle all enumerations in _Py_ANNOTATE_MEMORY_ORDER |
| to allow compiling extension modules with -Wswitch-enum on gcc. |
| Initial patch by Floris Bruynooghe. |
| |
| - Issue #10227: Add an allocation cache for a single slice object. Patch by |
| Stefan Behnel. |
| |
| - Issue #13393: BufferedReader.read1() now asks the full requested size to |
| the raw stream instead of limiting itself to the buffer size. |
| |
| - Issue #13392: Writing a pyc file should now be atomic under Windows as well. |
| |
| - Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder |
| already accepts them). |
| |
| - Issue #13389: Full garbage collection passes now clear the freelists for |
| list and dict objects. They already cleared other freelists in the |
| interpreter. |
| |
| - Issue #13327: Remove the need for an explicit None as the second argument |
| to os.utime, os.lutimes, os.futimes, os.futimens, os.futimesat, in |
| order to update to the current time. Also added keyword argument |
| handling to os.utimensat in order to remove the need for explicit None. |
| |
| - Issue #13350: Simplify some C code by replacing most usages of |
| PyUnicode_Format by PyUnicode_FromFormat. |
| |
| - Issue #13342: input() used to ignore sys.stdin's and sys.stdout's unicode |
| error handler in interactive mode (when calling into PyOS_Readline()). |
| |
| - Issue #9896: Add start, stop, and step attributes to range objects. |
| |
| - Issue #13343: Fix a SystemError when a lambda expression uses a global |
| variable in the default value of a keyword-only argument: ``lambda *, |
| arg=GLOBAL_NAME: None`` |
| |
| - Issue #12797: Added custom opener parameter to builtin open() and |
| FileIO.open(). |
| |
| - Issue #10519: Avoid unnecessary recursive function calls in |
| setobject.c. |
| |
| - Issue #10363: Deallocate global locks in Py_Finalize(). |
| |
| - Issue #13018: Fix reference leaks in error paths in dictobject.c. |
| Patch by Suman Saha. |
| |
| - Issue #13201: Define '==' and '!=' to compare range objects based on |
| the sequence of values they define (instead of comparing based on |
| object identity). |
| |
| - Issue #1294232: In a few cases involving metaclass inheritance, the |
| interpreter would sometimes invoke the wrong metaclass when building a new |
| class object. These cases now behave correctly. Patch by Daniel Urban. |
| |
| - Issue #12753: Add support for Unicode name aliases and named sequences. |
| Both ``unicodedata.lookup()`` and '\N{...}' now resolve aliases, |
| and ``unicodedata.lookup()`` resolves named sequences too. |
| |
| - Issue #12170: The count(), find(), rfind(), index() and rindex() methods |
| of bytes and bytearray objects now accept an integer between 0 and 255 |
| as their first argument. Patch by Petri Lehtinen. |
| |
| - Issue #12604: VTRACE macro expanded to no-op in _sre.c to avoid compiler |
| warnings. Patch by Josh Triplett and Petri Lehtinen. |
| |
| - Issue #12281: Rewrite the MBCS codec to handle correctly replace and ignore |
| error handlers on all Windows versions. The MBCS codec is now supporting all |
| error handlers, instead of only replace to encode and ignore to decode. |
| |
| - Issue #13188: When called without an explicit traceback argument, |
| generator.throw() now gets the traceback from the passed exception's |
| ``__traceback__`` attribute. Patch by Petri Lehtinen. |
| |
| - Issue #13146: Writing a pyc file is now atomic under POSIX. |
| |
| - Issue #7833: Extension modules built using distutils on Windows will no |
| longer include a "manifest" to prevent them failing at import time in some |
| embedded situations. |
| |
| - PEP 3151 / issue #12555: reworking the OS and IO exception hierarchy. |
| |
| - Issue #13560: Add PyUnicode_DecodeLocale(), PyUnicode_DecodeLocaleAndSize() |
| and PyUnicode_EncodeLocale() functions to the C API to decode/encode from/to |
| the current locale encoding. |

| - Add internal API for static strings (_Py_identifier et al.). |
| |
| - Issue #13063: the Windows error ERROR_NO_DATA (numbered 232 and described |
| as "The pipe is being closed") is now mapped to POSIX errno EPIPE |
| (previously EINVAL). |
| |
| - Issue #12911: Fix memory consumption when calculating the repr() of huge |
| tuples or lists. |
| |

| and bytearray.split may now be passed as keyword arguments. |
| |

| as a keyword argument: "my_string.splitlines(keepends=True)". The same |
| change also applies to bytes.splitlines and bytearray.splitlines. |
| |
| - Issue #7732: Don't open a directory as a file anymore while importing a |
| module. Ignore the direcotry if its name matchs the module name (e.g. |
| "__init__.py") and raise a ImportError instead. |
| |
| - Issue #13021: Missing decref on an error path. Thanks to Suman Saha for |
| finding the bug and providing a patch. |
| |
| - Issue #12973: Fix overflow checks that relied on undefined behaviour in |
| list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These bugs |
| caused test failures with recent versions of Clang. |
| |
| - Issue #12904: os.utime, os.futimes, os.lutimes, and os.futimesat now write |
| atime and mtime with nanosecond precision on modern POSIX platforms. |
| |
| - Issue #12802: the Windows error ERROR_DIRECTORY (numbered 267) is now |
| mapped to POSIX errno ENOTDIR (previously EINVAL). |
| |
| - Issue #9200: The str.is* methods now work with strings that contain non-BMP |
| characters even in narrow Unicode builds. |
| |

| return the respective singleton instances. |
| |
| - Forbid summing bytes with sum(). |
| |
| - Verify the types of AST strings and identifiers provided by the user before |
| compiling them. |
| |
| - Issue #12647: The None object now has a __bool__() method that returns False. |
| Formerly, bool(None) returned False only because of special case logic |
| in PyObject_IsTrue(). |
| |
| - Issue #12579: str.format_map() now raises a ValueError if used on a |
| format string that contains positional fields. Initial patch by |
| Julian Berman. |

| non-exception class. |
| |
| - Issue #12149: Update the method cache after a type's dictionary gets |
| cleared by the garbage collector. This fixes a segfault when an instance |
| and its type get caught in a reference cycle, and the instance's |
| deallocator calls one of the methods on the type (e.g. when subclassing |
| IOBase). Diagnosis and patch by Davide Rizzo. |
| |
| - Issue #9611, #9015: FileIO.read() clamps the length to INT_MAX on Windows. |
| |
| - Issue #9642: Uniformize the tests on the availability of the mbcs codec, add |
| a new HAVE_MBCS define. |
| |
| - Issue #9642: Fix filesystem encoding initialization: use the ANSI code page |
| on Windows if the mbcs codec is not available, and fail with a fatal error if |
| we cannot get the locale encoding (if nl_langinfo(CODESET) is not available) |
| instead of using UTF-8. |
| |
| - When a generator yields, do not retain the caller's exception state on the |
| generator. |
| |
| - Issue #12475: Prevent generators from leaking their exception state into the |
| caller's frame as they return for the last time. |
| |
| - Issue #12291: You can now load multiple marshalled objects from a stream, |
| with other data interleaved between marshalled objects. |
| |
| - Issue #12356: When required positional or keyword-only arguments are not |
| given, produce a informative error message which includes the name(s) of the |
| missing arguments. |
| |
| - Issue #12370: Fix super with no arguments when __class__ is overriden in the |
| class body. |
| |
| - Issue #12084: os.stat on Windows now works properly with relative symbolic |

| - Issue #12225: Still allow Python to build if Python is not in its hg repo or |
| mercurial is not installed. |
| |

| - Issue #12106: The use of the multiple-with shorthand syntax is now reflected |
| in the AST. |
| |
| - Issue #12190: Try to use the same filename object when compiling unmarshalling |
| a code objects in the same file. |
| |
| - Issue #12166: Move implementations of dir() specialized for various types into |
| the __dir__() methods of those types. |
| |
| - Issue #5715: In socketserver, close the server socket in the child process. |
| |
| - Correct lookup of __dir__ on objects. Among other things, this causes errors |
| besides AttributeError found on lookup to be propagated. |

| - Issue #1195: Fix input() if it is interrupted by CTRL+d and then CTRL+c, |
| clear the end-of-file indicator after CTRL+d. |
| |

| the check of the object type doesn't read the __class__ attribute anymore. |
| Fix a crash if a class override its __class__ attribute (e.g. a proxy of the |
| str type). Patch written by Andreas Stührk. |
| |
| - Issue #10517: After fork(), reinitialize the TLS used by the PyGILState_* |
| APIs, to avoid a crash with the pthread implementation in RHEL 5. Patch |
| by Charles-François Natali. |

| It encoded the Unicode filename to UTF-8, but the encoding fails on |
| undecodable filename (on surrogate characters) which raises an unexpected |
| UnicodeEncodeError on recursion limit. |
| |
| - Issue #11187: Remove bootstrap code (use ASCII) of |
| PyUnicode_AsEncodedString(), it was replaced by a better fallback (use the |
| locale encoding) in PyUnicode_EncodeFSDefault(). |

| |
| - Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building |
| Distutils-based packages with C extension modules may fail because |
| Apple has removed gcc-4.2, the version used to build python.org |
| 64-bit/32-bit Pythons. If the user does not explicitly override |
| the default C compiler by setting the CC environment variable, |
| Distutils will now attempt to compile extension modules with clang |
| if gcc-4.2 is required but not found. Also as a convenience, if |
| the user does explicitly set CC, substitute its value as the default |
| compiler in the Distutils LDSHARED configuration variable for OS X. |
| (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u |
| SDK, neither of which are available in Xcode 4. This change does not |
| attempt to override settings to support their use with Xcode 4.) |

| |
| - Issue #10968: Remove indirection in threading. The public names (Event, |
| Condition, etc.) used to be factory functions returning instances of hidden |
| classes (_Event, _Condition, etc.), because (if Guido recalls correctly) this |
| code pre-dates the ability to subclass extension types. It is now possible |
| to inherit from these classes, without having to import the private |
| underscored names like multiprocessing did. |
| |
| - Issue #9723: Add shlex.quote functions, to escape filenames and command |
| lines. |

| directory, so that "import DLFCN" and other similar imports work on |
| Linux 3.0. |
| |
| - Issue #7484: smtplib no longer puts <> around addresses in VRFY and EXPN |
| commands; they aren't required and in fact postfix doesn't support that form. |
| |
| - Issue #12273: Remove ast.__version__. AST changes can be accounted for by |
| checking sys.version_info or sys._mercurial. |
| |
| - Silence spurious "broken pipe" tracebacks when shutting down a |
| ProcessPoolExecutor. |
| |
| - Fix potential resource leaks in concurrent.futures.ProcessPoolExecutor |

| to make HTTP POST requests, and make sure it uses CRLF. |
| |
| - Issue #12016: Multibyte CJK decoders now resynchronize faster. They only |
| ignore the first byte of an invalid byte sequence. For example, |
| b'\xff\n'.decode('gb2312', 'replace') gives '\ufffd\n' instead of '\ufffd'. |
| |
| - Issue #12459: time.sleep() now raises a ValueError if the sleep length is |
| negative, instead of an infinite sleep on Windows or raising an IOError on |
| Linux for example, to have the same behaviour on all platforms. |
| |
| - Issue #12451: pydoc: html_getfile() now uses tokenize.open() to support |
| Python scripts using a encoding different than UTF-8 (read the coding cookie |
| of the script). |
| |
| - Issue #12493: subprocess: Popen.communicate() now also handles EINTR errors |

| instead of text mode using the locale encoding, to avoid encoding issues. |
| |
| - Issue #12451: runpy: run_path() now opens the Python script in binary mode, |
| instead of text mode using the locale encoding, to support other encodings |
| than UTF-8 (scripts using the coding cookie). |
| |
| - Issue #12451: xml.dom.pulldom: parse() now opens files in binary mode instead |
| of the text mode (using the locale encoding) to avoid encoding issues. |

| the garbage collector while the Heap lock is held. |
| |
| - Issue #12462: time.sleep() now immediately calls the (Python) signal handler |

| instruction. |
| |
| - Issue #12442: new shutil.disk_usage function, providing total, used and free |
| disk space statistics. |
| |
| - Issue #12451: The XInclude default loader of xml.etree now decodes files from |
| UTF-8 instead of the locale encoding if the encoding is not specified. It now |
| also opens XML files for the parser in binary mode instead of the text mode |
| to avoid encoding issues. |
| |
| - Issue #12451: doctest.debug_script() doesn't create a temporary file |
| anymore to avoid encoding issues. |
| |
| - Issue #12451: pydoc.synopsis() now reads the encoding cookie if available, |
| to read the Python script from the right encoding. |
| |
| - Issue #12451: distutils now opens the setup script in binary mode to read the |
| encoding cookie, instead of opening it in UTF-8. |
| |
| - Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to |
| check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the |
| interpreter process. This could cause failures in non-Distutils subprocesses |
| and was unreliable since tests or user programs could modify the interpreter |
| environment after Distutils set it. Instead, have Distutils set the |
| deployment target only in the environment of each build subprocess. It is |
| still possible to globally override the default by setting |
| MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be |
| greater or equal to the default value, the value with which the interpreter |
| was built. Also, implement the same handling in packaging. |
| |
| - Issue #12422: In the copy module, don't store objects that are their own copy |
| in the memo dict. |

| - Issue #11637: Fix support for importing packaging setup hooks from the |
| project directory. |
| |
| - Issue #6771: Moved the curses.wrapper function from the single-function |
| wrapper module into __init__, eliminating the module. Since __init__ was |
| already importing the function to curses.wrapper, there is no API change. |
| |
| - Issue #11584: email.header.decode_header no longer fails if the header |
| passed to it is a Header object, and Header/make_header no longer fail |
| if given binary unknown-8bit input. |
| |
| - Issue #11700: mailbox proxy object close methods can now be called multiple |
| times without error. |

| Tests |
| ----- |
| |
| - Issue #11689: Fix a variable scoping error in an sqlite3 test |
| |
| - Issue #13786: Remove unimplemented 'trace' long option from regrtest.py. |
| |
| - Issue #13725: Fix regrtest to recognize the documented -d flag. |
| Patch by Erno Tukia. |
| |
| - Issue #13304: Skip test case if user site-packages disabled (-s or |
| PYTHONNOUSERSITE). (Patch by Carl Meyer) |
| |
| - Issue #5661: Add a test for ECONNRESET/EPIPE handling to test_asyncore. Patch |
| by Xavier de Gaye. |
| |
| - Issue #13218: Fix test_ssl failures on Debian/Ubuntu. |
| |

| |
| - Issue #6484: Add unit tests for mailcap module (patch by Gregory Nofi) |
| |
| - Issue #11651: Improve the Makefile test targets to run more of the test suite |
| more quickly. The --multiprocess option is now enabled by default, reducing |
| the amount of time needed to run the tests. "make test" and "make quicktest" |
| now include some resource-intensive tests, but no longer run the test suite |
| twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides |
| an easy platform-independent way to run test suite with sensible defaults. |
| |
| - Issue #12331: The test suite for the packaging module can now run from an |
| installed Python. |

| - Issue #12626: In regrtest, allow to filter tests using a glob filter |
| with the ``-m`` (or ``--match``) option. This works with all test cases |
| using the unittest module. This is useful with long test suites |
| such as test_io or test_subprocess. |
| |
| - Issue #12624: It is now possible to fail after the first failure when |
| running in verbose mode (``-v`` or ``-W``), by using the ``--failfast`` |
| (or ``-G``) option to regrtest. This is useful with long test suites |
| such as test_io or test_subprocess. |
| |
| - Issue #12587: Correct faulty test file and reference in test_tokenize. |
| (Patch by Robert Xiao) |
| |
| - Issue #12573: Add resource checks for dangling Thread and Process objects. |

| |
| - Skip network tests when getaddrinfo() returns EAI_AGAIN, meaning a temporary |
| failure in name resolution. |
| |
| - Issue #11812: Solve transient socket failure to connect to 'localhost' |
| in test_telnetlib.py. |
| |
| - Solved a potential deadlock in test_telnetlib.py. Related to issue #11812. |
| |
| - Avoid failing in test_robotparser when mueblesmoraleda.com is flaky and |
| an overzealous DNS service (e.g. OpenDNS) redirects to a placeholder |
| Web site. |
| |
| - Avoid failing in test_urllibnet.test_bad_address when some overzealous |
| DNS service (e.g. OpenDNS) resolves a non-existent domain name. The test |
| is now skipped instead. |
| |
| - Issue #12440: When testing whether some bits in SSLContext.options can be |
| reset, check the version of the OpenSSL headers Python was compiled against, |
| rather than the runtime version of the OpenSSL library. |
| |
| - Issue #11512: Add a test suite for the cgitb module. Patch by Robbie Clemons. |
| |
| - Issue #12497: Install test/data to prevent failures of the various codecmaps |
| tests. |
| |
| - Issue #12496: Install test/capath directory to prevent test_connect_capath |
| testcase failure in test_ssl. |
| |
| - Issue #12469: Run wakeup and pending signal tests in a subprocess to run the |
| test in a fresh process with only one thread and to not change signal |
| handling of the parent process. |
| |
| - Issue #8716: Avoid crashes caused by Aqua Tk on OSX when attempting to run |
| test_tk or test_ttk_guionly under a username that is not currently logged |
| in to the console windowserver (as may be the case under buildbot or ssh). |
| |
| - Issue #12407: Explicitly skip test_capi.EmbeddingTest under Windows. |
| |
| - Issue #12400: regrtest -W doesn't rerun the tests twice anymore, but captures |
| the output and displays it on failure instead. regrtest -v doesn't print the |
| error twice anymore if there is only one error. |
| |
| - Issue #12141: Install copies of template C module file so that |
| test_build_ext of test_distutils and test_command_build_ext of |
| test_packaging are no longer silently skipped when |
| run outside of a build directory. |
| |
| - Issue #8746: Add additional tests for os.chflags() and os.lchflags(). |
| Patch by Garrett Cooper. |
| |
| - Issue #10736: Fix test_ttk test_widgets failures with Cocoa Tk 8.5.9 |
| 2.8 + on Mac OS X. (Patch by Ronald Oussoren) |
| |
| - Issue #12057: Add tests for ISO 2022 codecs (iso2022_jp, iso2022_jp_2, |

| when the randomly generated temporary path happened to match the regex. |
| |
| - Issue #11958: Fix FTP tests for IPv6, bind to "::1" instead of "localhost". |
| Patch written by Charles-Francois Natali. |

| - Issue #8407, #11859: Fix tests of test_io using threads and an alarm: use |
| pthread_sigmask() to ensure that the SIGALRM signal is received by the main |
| thread. |
| |
| - Issue #11811: Factor out detection of IPv6 support on the current host |
| and make it available as ``test.support.IPV6_ENABLED``. Patch by |
| Charles-François Natali. |
| |
| - Issue #10914: Add a minimal embedding test to test_capi. |
| |
| - Issue #11223: Skip test_lock_acquire_interruption() and |
| test_rlock_acquire_interruption() of test_threadsignals if a thread lock is |
| implemented using a POSIX mutex and a POSIX condition variable. A POSIX |
| condition variable cannot be interrupted by a signal (e.g. on Linux, the |
| futex system call is restarted). |
