| Library |
| ------- |
| |
| - Issue #20710: The pydoc summary line no longer displays the "self" parameter |
| for bound methods. |
| |
| - Issue #20566: Change asyncio.as_completed() to use a Queue, to |
| avoid O(N**2) behavior. |
| |
| - Issue #20704: Implement new debug API in asyncio. Add new methods |
| BaseEventLoop.set_debug() and BaseEventLoop.get_debug(). |
| Add support for setting 'asyncio.tasks._DEBUG' variable with |
| 'PYTHONASYNCIODEBUG' environment variable. |
| |
| - asyncio: Refactoring and fixes: BaseEventLoop.sock_connect() raises an |
| error if the address is not resolved; use __slots__ in Handle and |
| TimerHandle; as_completed() and wait() raise TypeError if the passed |
| list of Futures is a single Future; call_soon() and other 'call_*()' |
| functions raise TypeError if the passed callback is a coroutine |
| function; _ProactorBasePipeTransport uses _FlowControlMixin; |
| WriteTransport.set_write_buffer_size() calls _maybe_pause_protocol() |
| to consider pausing receiving if the watermark limits have changed; |
| fix _check_resolved_address() for IPv6 address; and other minor |
| improvements, along with multiple documentation updates. |

| |
| - Issue #20616: Add a format() method to tracemalloc.Traceback. |
| |
| - Issue #19744: the ensurepip installation step now just prints a warning to |
| stderr rather than failing outright if SSL/TLS is unavailable. This allows |
| local installation of POSIX builds without SSL/TLS support. |
| |
| - Issue #20594: Avoid name clash with the libc function posix_close. |
| |
| Build |
| ----- |
| |

| What's New in Python 3.4.0 release candidate 1? |
| =============================================== |
| |
| Release date: 2014-02-10 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #19255: The builtins module is restored to initial value before |
| cleaning other modules. The sys and builtins modules are cleaned last. |
| |
| - Issue #20588: Make Python-ast.c C89 compliant. |
| |
| - Issue #20437: Fixed 22 potential bugs when deleting objects references. |
| |
| - Issue #20500: Displaying an exception at interpreter shutdown no longer |
| risks triggering an assertion failure in PyObject_Str. |
| |
| - Issue #20538: UTF-7 incremental decoder produced inconsistent string when |
| input was truncated in BASE64 section. |
| |
| - Issue #20404: io.TextIOWrapper (and hence the open() builtin) now uses the |
| internal codec marking system added for issue #19619 to throw LookupError |
| for known non-text encodings at stream construction time. The existing |
| output type checks remain in place to deal with unmarked third party |
| codecs. |
| |
| - Issue #17162: Add PyType_GetSlot. |
| |
| - Issue #20162: Fix an alignment issue in the siphash24() hash function which |
| caused a crash on PowerPC 64-bit (ppc64). |
| |
| Library |
| ------- |
| |
| - Issue #20530: The signatures for slot builtins have been updated |
| to reflect the fact that they only accept positional-only arguments. |
| |
| - Issue #20517: Functions in the os module that accept two filenames |
| now register both filenames in the exception on failure. |
| |
| - Issue #20563: The ipaddress module API is now considered stable. |
| |
| - Issue #14983: email.generator now always adds a line end after each MIME |
| boundary marker, instead of doing so only when there is an epilogue. This |
| fixes an RFC compliance bug and solves an issue with signed MIME parts. |
| |
| - Issue #20540: Fix a performance regression (vs. Python 3.2) when layering |
| a multiprocessing Connection over a TCP socket. For small payloads, Nagle's |
| algorithm would introduce idle delays before the entire transmission of a |
| message. |
| |
| - Issue #16983: the new email header parsing code will now decode encoded words |
| that are (incorrectly) surrounded by quotes, and register a defect. |
| |
| - Issue #19772: email.generator no longer mutates the message object when |
| doing a down-transform from 8bit to 7bit CTEs. |
| |
| - Issue #20536: the statistics module now correctly handle Decimal instances |
| with positive exponents |
| |
| - Issue #18805: the netmask/hostmask parsing in ipaddress now more reliably |
| filters out illegal values and correctly allows any valid prefix length. |
| |
| - Issue #20481: For at least Python 3.4, the statistics module will require |
| that all inputs for a single operation be of a single consistent type, or |
| else a mixed of ints and a single other consistent type. This avoids |
| some interoperability issues that arose with the previous approach of |
| coercing to a suitable common type. |
| |
| - Issue #20478: the statistics module now treats collections.Counter inputs |
| like any other iterable. |
| |
| - Issue #17369: get_filename was raising an exception if the filename |
| parameter's RFC2231 encoding was broken in certain ways. This was |
| a regression relative to python2. |
| |
| - Issue #20013: Some imap servers disconnect if the current mailbox is |
| deleted, and imaplib did not handle that case gracefully. Now it |
| handles the 'bye' correctly. |
| |
| - Issue #20531: Revert 3.4 version of fix for #19063, and apply the 3.3 |
| version. That is, do *not* raise an error if unicode is passed to |
| email.message.Message.set_payload. |
| |
| - Issue #20476: If a non-compat32 policy is used with any of the email parsers, |
| EmailMessage is now used as the factory class. The factory class should |
| really come from the policy; that will get fixed in 3.5. |
| |
| - Issue #19920: TarFile.list() no longer fails when outputs a listing |
| containing non-encodable characters. Based on patch by Vajrasky Kok. |
| |
| - Issue #20515: Fix NULL pointer dereference introduced by issue #20368. |
| |
| - Issue #19186: Restore namespacing of expat symbols inside the pyexpat module. |
| |
| - Issue #20053: ensurepip (and hence venv) are no longer affected by the |
| settings in the default pip configuration file. |
| |
| - Issue #20426: When passing the re.DEBUG flag, re.compile() displays the |
| debug output every time it is called, regardless of the compilation cache. |
| |
| - Issue #20368: The null character now correctly passed from Tcl to Python. |
| Improved error handling in variables-related commands. |
| |
| - Issue #20435: Fix _pyio.StringIO.getvalue() to take into account newline |
| translation settings. |
| |
| - tracemalloc: Fix slicing traces and fix slicing a traceback. |
| |
| - Issue #20354: Fix an alignment issue in the tracemalloc module on 64-bit |
| platforms. Bug seen on 64-bit Linux when using "make profile-opt". |
| |
| - Issue #17159: inspect.signature now accepts duck types of functions, |
| which adds support for Cython functions. Initial patch by Stefan Behnel. |
| |
| - Issue #18801: Fix inspect.classify_class_attrs to correctly classify |
| object.__new__ and object.__init__. |
| |
| - Fixed cmath.isinf's name in its argument parsing code. |
| |
| - Issue #20311, #20452: poll and epoll now round the timeout away from zero, |
| instead of rounding towards zero, in select and selectors modules: |
| select.epoll.poll(), selectors.PollSelector.poll() and |
| selectors.EpollSelector.poll(). For example, a timeout of one microsecond |
| (1e-6) is now rounded to one millisecondi (1e-3), instead of being rounded to |
| zero. However, the granularity property and asyncio's resolution feature |
| were removed again. |
| |
| - asyncio: Some refactoring; various fixes; add write flow control to |
| unix pipes; Future.set_exception() instantiates the exception |
| argument if it is a class; improved proactor pipe transport; support |
| wait_for(f, None); don't log broken/disconnected pipes; use |
| ValueError instead of assert for forbidden subprocess_{shell,exec} |
| arguments; added a convenience API for subprocess management; added |
| StreamReader.at_eof(); properly handle duplicate coroutines/futures |
| in gather(), wait(), as_completed(); use a bytearray for buffering |
| in StreamReader; and more. |
| |
| - Issue #20288: fix handling of invalid numeric charrefs in HTMLParser. |
| |
| - Issue #20424: Python implementation of io.StringIO now supports lone surrogates. |
| |
| - Issue #20308: inspect.signature now works on classes without user-defined |
| __init__ or __new__ methods. |
| |
| - Issue #20372: inspect.getfile (and a bunch of other inspect functions that |
| use it) doesn't crash with unexpected AttributeError on classes defined in C |
| without __module__. |
| |
| - Issue #20356: inspect.signature formatting uses '/' to separate |
| positional-only parameters from others. |
| |
| - Issue #20223: inspect.signature now supports methods defined with |
| functools.partialmethods. |
| |
| - Issue #19456: ntpath.join() now joins relative paths correctly when a drive |
| is present. |
| |
| - Issue #19077: tempfile.TemporaryDirectory cleanup no longer fails when |
| called during shutdown. Emitting resource warning in __del__ no longer fails. |
| Original patch by Antoine Pitrou. |
| |
| - Issue #20394: Silence Coverity warning in audioop module. |
| |
| - Issue #20367: Fix behavior of concurrent.futures.as_completed() for |
| duplicate arguments. Patch by Glenn Langford. |
| |
| - Issue #8260: The read(), readline() and readlines() methods of |
| codecs.StreamReader returned incomplete data when were called after |
| readline() or read(size). Based on patch by Amaury Forgeot d'Arc. |

| traceback of the original exception as its __traceback__ attribute. |
| |
| - Issue #17481: inspect.getfullargspec() now uses inspect.signature() API. |
| |
| - Issue #15304: concurrent.futures.wait() can block forever even if |
| Futures have completed. Patch by Glenn Langford. |
| |
| - Issue #14455: plistlib: fix serializing integers integers in the range |
| of an unsigned long long but outside of the range of signed long long for |
| binary plist files. |
| |
| IDLE |
| ---- |
| |
| - Issue #20406: Use Python application icons for Idle window title bars. |
| Patch mostly by Serhiy Storchaka. |
| |
| - Update the python.gif icon for the Idle classbrowser and pathbowser |
| from the old green snake to the new new blue and yellow snakes. |
| |
| - Issue #17721: Remove non-functional configuration dialog help button until we |
| make it actually gives some help when clicked. Patch by Guilherme Simões. |
| |
| Tests |
| ----- |
| |
| - Issue #20532: Tests which use _testcapi now are marked as CPython only. |
| |
| - Issue #19920: Added tests for TarFile.list(). Based on patch by Vajrasky Kok. |
| |
| - Issue #19990: Added tests for the imghdr module. Based on patch by |
| Claudiu Popa. |
| |
| - Issue #20474: Fix test_socket "unexpected success" failures on OS X 10.7+. |
| |
| Tools/Demos |
| ----------- |
| |
| - Issue #20530: Argument Clinic's signature format has been revised again. |
| The new syntax is highly human readable while still preventing false |
| positives. The syntax also extends Python syntax to denote "self" and |
| positional-only parameters, allowing inspect.Signature objects to be |
| totally accurate for all supported builtins in Python 3.4. |
| |
| - Issue #20456: Argument Clinic now observes the C preprocessor conditional |
| compilation statements of the C files it parses. When a Clinic block is |
| inside a conditional code, it adjusts its output to match, including |
| automatically generating an empty methoddef macro. |
| |
| - Issue #20456: Cloned functions in Argument Clinic now use the correct |
| name, not the name of the function they were cloned from, for text |
| strings inside generated code. |
| |
| - Issue #20456: Fixed Argument Clinic's test suite and "--converters" feature. |
| |
| - Issue #20456: Argument Clinic now allows specifying different names |
| for a parameter in Python and C, using "as" on the parameter line. |
| |
| - Issue #20326: Argument Clinic now uses a simple, unique signature to |
| annotate text signatures in docstrings, resulting in fewer false |
| positives. "self" parameters are also explicitly marked, allowing |
| inspect.Signature() to authoritatively detect (and skip) said parameters. |
| |
| - Issue #20326: Argument Clinic now generates separate checksums for the |
| input and output sections of the block, allowing external tools to verify |
| that the input has not changed (and thus the output is not out-of-date). |
| |
| Build |
| ----- |
| |
| - Issue #20465: Update SQLite shipped with OS X installer to 3.8.3. |
| |
| C-API |
| ----- |
| |
| - Issue #20517: Added new functions allowing OSError exceptions to reference |
| two filenames instead of one: PyErr_SetFromErrnoWithFilenameObjects() and |
| PyErr_SetExcFromWindowsErrWithFilenameObjects(). |
| |
| Documentation |
| ------------- |
| |
| - Issue #20488: Change wording to say importlib is *the* implementation of |
| import instead of just *an* implementation. |
| |
| - Issue #6386: Clarify in the tutorial that specifying a symlink to execute |
| means the directory containing the executed script and not the symlink is |
| added to sys.path. |
| |
| |
| What's New in Python 3.4.0 Beta 3? |
| ================================== |
| |
| Release date: 2014-01-26 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #20189: Four additional builtin types (PyTypeObject, |
| PyMethodDescr_Type, _PyMethodWrapper_Type, and PyWrapperDescr_Type) |
| have been modified to provide introspection information for builtins. |
| |
| - Issue #17825: Cursor "^" is correctly positioned for SyntaxError and |
| IndentationError. |
| |
| - Issue #2382: SyntaxError cursor "^" is now written at correct position in most |
| cases when multibyte characters are in line (before "^"). This still not |
| works correctly with wide East Asian characters. |
| |
| - Issue #18960: The first line of Python script could be executed twice when |
| the source encoding was specified on the second line. Now the source encoding |
| declaration on the second line isn't effective if the first line contains |
| anything except a comment. 'python -x' works now again with files with the |
| source encoding declarations, and can be used to make Python batch files |
| on Windows. |
| |
| Library |
| ------- |
| |
| - asyncio: Various improvements and small changes not all covered by |
| issues listed below. E.g. wait_for() now cancels the inner task if |
| the timeout occcurs; tweaked the set of exported symbols; renamed |
| Empty/Full to QueueEmpty/QueueFull; "with (yield from lock)" now |
| uses a separate context manager; readexactly() raises if not enough |
| data was read; PTY support tweaks. |
| |
| - Issue #20311: asyncio: Add a granularity attribute to BaseEventLoop: maximum |
| between the resolution of the BaseEventLoop.time() method and the resolution |
| of the selector. The granuarility is used in the scheduler to round time and |
| deadline. |
| |
| - Issue #20311: selectors: Add a resolution attribute to BaseSelector. |
| |
| - Issue #20189: unittest.mock now no longer assumes that any object for |
| which it could get an inspect.Signature is a callable written in Python. |
| Fix courtesy of Michael Foord. |
| |
| - Issue #20317: ExitStack.__exit__ could create a self-referential loop if an |
| exception raised by a cleanup operation already had its context set |
| correctly (for example, by the @contextmanager decorator). The infinite |
| loop this caused is now avoided by checking if the expected context is |
| already set before trying to fix it. |
| |
| - Issue #20374: Fix build with GNU readline >= 6.3. |
| |
| - Issue #20262: Warnings are raised now when duplicate names are added in the |
| ZIP file or too long ZIP file comment is truncated. |

| - Issue #20245: The open functions in the tarfile module now correctly handle |
| empty mode. |
| |
| - Issue #20242: Fixed basicConfig() format strings for the alternative |
| formatting styles. Thanks to kespindler for the bug report and patch. |
| |
| - Issue #20246: Fix buffer overflow in socket.recvfrom_into. |
| |
| - Issues #20206 and #5803: Fix edge case in email.quoprimime.encode where it |
| truncated lines ending in a character needing encoding but no newline by |
| using a more efficient algorithm that doesn't have the bug. |
| |
| - Issue #19082: Working xmlrpc.server and xmlrpc.client examples. Both in |
| modules and in documentation. Initial patch contributed by Vajrasky Kok. |
| |
| - Issue #20138: The wsgiref.application_uri() and wsgiref.request_uri() |
| functions now conform to PEP 3333 when handle non-ASCII URLs. |
| |

| invalid fileobj. |
| |
| - Issue #20152: Ported Python/import.c over to Argument Clinic. |

| on the second line if the first line contains anything except a comment. |
| |
| - Issue #20078: Reading malformed zipfiles no longer hangs with 100% CPU |
| consumption. |
| |
| - Issue #20113: os.readv() and os.writev() now raise an OSError exception on |
| error instead of returning -1. |
| |
| - Issue #19719: Make importlib.abc.MetaPathFinder.find_module(), |
| PathEntryFinder.find_loader(), and Loader.load_module() use PEP 451 APIs to |
| help with backwards-compatibility. |
| |
| - Issue #20144: inspect.Signature now supports parsing simple symbolic |
| constants as parameter default values in __text_signature__. |
| |
| - Issue #20072: Fixed multiple errors in tkinter with wantobjects is False. |
| |
| - Issue #20229: Avoid plistlib deprecation warning in platform.mac_ver(). |
| |
| - Issue #14455: Fix some problems with the new binary plist support in plistlib. |
| |
| IDLE |
| ---- |
| |
| - Issue #17390: Add Python version to Idle editor window title bar. |
| Original patches by Edmond Burnett and Kent Johnson. |
| |
| - Issue #18960: IDLE now ignores the source encoding declaration on the second |
| line if the first line contains anything except a comment. |
| |
| Tests |
| ----- |
| |
| - Issue #20358: Tests for curses.window.overlay and curses.window.overwrite |
| no longer specify min{row,col} > max{row,col}. |
| |
| - Issue #19804: The test_find_mac test in test_uuid is now skipped if the |
| ifconfig executable is not available. |
| |
| - Issue #19886: Use better estimated memory requirements for bigmem tests. |
| |
| Tools/Demos |
| ----------- |
| |
| - Issue #20390: Argument Clinic's "file" output preset now defaults to |
| "{dirname}/clinic/{basename}.h". |
| |
| - Issue #20390: Argument Clinic's "class" directive syntax has been extended |
| with two new required arguments: "typedef" and "type_object". |
| |
| - Issue #20390: Argument Clinic: If __new__ or __init__ functions didn't use |
| kwargs (or args), the PyArg_NoKeywords (or PyArg_NoPositional) calls |
| generated are only run when the type object is an exact match. |
| |
| - Issue #20390: Argument Clinic now fails if you have required parameters after |
| optional parameters. |
| |
| - Issue #20390: Argument Clinic converters now have a new template they can |
| inject code into: "modifiers". Code put there is run in the parsing |
| function after argument parsing but before the call to the impl. |
| |
| - Issue #20376: Argument Clinic now escapes backslashes in docstrings. |
| |
| - Issue #20381: Argument Clinic now sanity checks the default argument when |
| c_default is also specified, providing a nice failure message for |
| disallowed values. |
| |
| - Issue #20189: Argument Clinic now ensures that parser functions for |
| __new__ are always of type newfunc, the type of the tp_new slot. |
| Similarly, parser functions for __init__ are now always of type initproc, |
| the type of tp_init. |
| |
| - Issue #20189: Argument Clinic now suppresses the docstring for __new__ |
| and __init__ functions if no docstring is provided in the input. |
| |
| - Issue #20189: Argument Clinic now suppresses the "self" parameter in the |
| impl for @staticmethod functions. |
| |
| - Issue #20294: Argument Clinic now supports argument parsing for __new__ and |
| __init__ functions. |
| |
| - Issue #20299: Argument Clinic custom converters may now change the default |
| value of c_default and py_default with a class member. |
| |
| - Issue #20287: Argument Clinic's output is now configurable, allowing |
| delaying its output or even redirecting it to a separate file. |
| |
| - Issue #20226: Argument Clinic now permits simple expressions |
| (e.g. "sys.maxsize - 1") as default values for parameters. |
| |
| - Issue #19936: Added executable bits or shebang lines to Python scripts which |
| requires them. Disable executable bits and shebang lines in test and |
| benchmark files in order to prevent using a random system python, and in |
| source files of modules which don't provide command line interface. Fixed |
| shebang lines in the unittestgui and checkpip scripts. |

| What's New in Python 3.4.0 Beta 2? |
| ================================== |
| |
| Release date: 2014-01-05 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #17432: Drop UCS2 from names of Unicode functions in python3.def. |
| |
| - Issue #19526: Exclude all new API from the stable ABI. Exceptions can be |
| made if a need is demonstrated. |
| |
| - Issue #19969: PyBytes_FromFormatV() now raises an OverflowError if "%c" |
| argument is not in range [0; 255]. |
| |
| - Issue #19995: %c, %o, %x, and %X now issue a DeprecationWarning on non-integer |
| input; reworded docs to clarify that an integer type should define both __int__ |
| and __index__. |
| |
| - Issue #19787: PyThread_set_key_value() now always set the value. In Python |
| 3.3, the function did nothing if the key already exists (if the current value |
| is a non-NULL pointer). |
| |
| - Issue #14432: Remove the thread state field from the frame structure. Fix a |
| crash when a generator is created in a C thread that is destroyed while the |
| generator is still used. The issue was that a generator contains a frame, and |
| the frame kept a reference to the Python state of the destroyed C thread. The |
| crash occurs when a trace function is setup. |
| |
| - Issue #19576: PyGILState_Ensure() now initializes threads. At startup, Python |
| has no concrete GIL. If PyGILState_Ensure() is called from a new thread for |
| the first time and PyEval_InitThreads() was not called yet, a GIL needs to be |
| created. |
| |
| - Issue #17576: Deprecation warning emitted now when __int__() or __index__() |
| return not int instance. |
| |
| - Issue #19932: Fix typo in import.h, missing whitespaces in function prototypes. |
| |
| - Issue #19736: Add module-level statvfs constants defined for GNU/glibc |
| based systems. |
| |
| - Issue #20097: Fix bad use of "self" in importlib's WindowsRegistryFinder. |
| |
| - Issue #19729: In str.format(), fix recursive expansion in format spec. |
| |
| - Issue #19638: Fix possible crash / undefined behaviour from huge (more than 2 |
| billion characters) input strings in _Py_dg_strtod. |
| |
| Library |
| ------- |

| |
| - Issue #16113: Remove sha3 module again. |
| |
| - Issue #20111: pathlib.Path.with_suffix() now sanity checks the given suffix. |
| |
| - Fix breakage in TestSuite.countTestCases() introduced by issue #11798. |

| - Issue #20108: Avoid parameter name clash in inspect.getcallargs(). |
| |
| - Issue #19918: Fix PurePath.relative_to() under Windows. |
| |
| - Issue #19422: Explicitly disallow non-SOCK_STREAM sockets in the ssl |
| module, rather than silently let them emit clear text data. |
| |
| - Issue #20046: Locale alias table no longer contains entities which can be |
| calculated. Generalized support of the euro modifier. |
| |
| - Issue #20027: Fixed locale aliases for devanagari locales. |
| |
| - Issue #20067: Tkinter variables now work when wantobjects is false. |
| |
| - Issue #19020: Tkinter now uses splitlist() instead of split() in configure |
| methods. |
| |
| - Issue #19744: ensurepip now provides a better error message when Python is |
| built without SSL/TLS support (pip currently requires that support to run, |
| even if only operating with local wheel files) |
| |
| - Issue #19734: ensurepip now ignores all pip environment variables to avoid |
| odd behaviour based on user configuration settings |
| |
| - Fix TypeError on "setup.py upload --show-response". |
| |
| - Issue #20045: Fix "setup.py register --list-classifiers". |
| |
| - Issue #18879: When a method is looked up on a temporary file, avoid closing |
| the file before the method is possibly called. |
| |
| - Issue #20037: Avoid crashes when opening a text file late at interpreter |
| shutdown. |
| |
| - Issue #19967: Thanks to the PEP 442, asyncio.Future now uses a |
| destructor to log uncaught exceptions, instead of the dedicated |
| _TracebackLogger class. |
| |
| - Added a Task.current_task() class method to asyncio. |
| |
| - Issue #19850: Set SA_RESTART in asyncio when registering a signal |
| handler to limit EINTR occurrences. |
| |
| - Implemented write flow control in asyncio for proactor event loop (Windows). |
| |
| - Change write buffer in asyncio use to avoid O(N**2) behavior. Make |
| write()/sendto() accept bytearray/memoryview. |
| |
| - Issue #20034: Updated alias mapping to most recent locale.alias file |
| from X.org distribution using makelocalealias.py. |
| |
| - Issue #5815: Fixed support for locales with modifiers. Fixed support for |
| locale encodings with hyphens. |
| |
| - Issue #20026: Fix the sqlite module to handle correctly invalid isolation |
| level (wrong type). |
| |
| - Issue #18829: csv.Dialect() now checks type for delimiter, escapechar and |
| quotechar fields. Original patch by Vajrasky Kok. |
| |
| - Issue #19855: uuid.getnode() on Unix now looks on the PATH for the |
| executables used to find the mac address, with /sbin and /usr/sbin as |
| fallbacks. |
| |
| - Issue #20007: HTTPResponse.read(0) no more prematurely closes connection. |
| Original patch by Simon Sapin. |
| |
| - Issue #19946: multiprocessing now uses runpy to initialize __main__ in |
| child processes when necessary, allowing it to correctly handle scripts |
| without suffixes and submodules that use explicit relative imports or |
| otherwise rely on parent modules being correctly imported prior to |
| execution. |
| |
| - Issue #19921: When Path.mkdir() is called with parents=True, any missing |
| parent is created with the default permissions, ignoring the mode argument |
| (mimicking the POSIX "mkdir -p" command). |
| |
| - Issue #19887: Improve the Path.resolve() algorithm to support certain |
| symlink chains. |
| |
| - Issue #19912: Fixed numerous bugs in ntpath.splitunc(). |
| |
| - Issue #19911: ntpath.splitdrive() now correctly processes the 'İ' character |
| (U+0130, LATIN CAPITAL LETTER I WITH DOT ABOVE). |
| |
| - Issue #19532: python -m compileall with no filename/directory arguments now |
| respects the -f and -q flags instead of ignoring them. |
| |
| - Issue #19623: Fixed writing to unseekable files in the aifc module. |
| |
| - Issue #19946: multiprocessing.spawn now raises ImportError when the module to |
| be used as the main module cannot be imported. |
| |
| - Issue #17919: select.poll.register() again works with poll.POLLNVAL on AIX. |
| Fixed integer overflow in the eventmask parameter. |
| |
| - Issue #19063: if a Charset's body_encoding was set to None, the email |
| package would generate a message claiming the Content-Transfer-Encoding |
| was 7bit, and produce garbage output for the content. This now works. |
| A couple of other set_payload mishandlings of non-ASCII are also fixed. |
| In addition, calling set_payload with a string argument without |
| specifying a charset now raises an error (this is a new error in 3.4). |
| |
| - Issue #15475: Add __sizeof__ implementations for itertools objects. |
| |
| - Issue #19944: Fix importlib.find_spec() so it imports parents as needed |
| and move the function to importlib.util. |
| |
| - Issue #19880: Fix a reference leak in unittest.TestCase. Explicitly break |
| reference cycles between frames and the _Outcome instance. |
| |
| - Issue #17429: platform.linux_distribution() now decodes files from the UTF-8 |
| encoding with the surrogateescape error handler, instead of decoding from the |
| locale encoding in strict mode. It fixes the function on Fedora 19 which is |
| probably the first major distribution release with a non-ASCII name. Patch |
| written by Toshio Kuratomi. |
| |
| - Issue #19343: Expose FreeBSD-specific APIs in resource module. Original |
| patch by Koobs. |
| |
| - Issue #19929: Call os.read with 32768 within subprocess.Popen.communicate |
| rather than 4096 for efficiency. A microbenchmark shows Linux and OS X |
| both using ~50% less cpu time this way. |
| |
| - Issue #19506: Use a memoryview to avoid a data copy when piping data |
| to stdin within subprocess.Popen.communicate. 5-10% less cpu usage. |
| |
| - Issue #19876: selectors unregister() no longer raises ValueError or OSError |
| if the FD is closed (as long as it was registered). |
| |
| - Issue #19908: pathlib now joins relative Windows paths correctly when a drive |
| is present. Original patch by Antoine Pitrou. |
| |
| - Issue #19296: Silence compiler warning in dbm_open |
| |
| - Issue #6784: Strings from Python 2 can now be unpickled as bytes |
| objects by setting the encoding argument of Unpickler to be 'bytes'. |
| Initial patch by Merlijn van Deen. |
| |
| - Issue #19839: Fix regression in bz2 module's handling of non-bzip2 data at |
| EOF, and analogous bug in lzma module. |
| |
| - Issue #19881: Fix pickling bug where cpickle would emit bad pickle data for |
| large bytes string (i.e., with size greater than 2**32-1). |
| |
| - Issue #19138: doctest's IGNORE_EXCEPTION_DETAIL now allows a match when |
| no exception detail exists (no colon following the exception's name, or |
| a colon does follow but no text follows the colon). |
| |
| - Issue #19927: Add __eq__ to path-based loaders in importlib. |
| |
| - Issue #19827: On UNIX, setblocking() and settimeout() methods of |
| socket.socket can now avoid a second syscall if the ioctl() function can be |
| used, or if the non-blocking flag of the socket is unchanged. |
| |
| - Issue #19785: smtplib now supports SSLContext.check_hostname and server name |
| indication for TLS/SSL connections. |
| |
| - Issue #19784: poplib now supports SSLContext.check_hostname and server name |
| indication for TLS/SSL connections. |
| |
| - Issue #19783: nntplib now supports SSLContext.check_hostname and server name |
| indication for TLS/SSL connections. |
| |
| - Issue #19782: imaplib now supports SSLContext.check_hostname and server name |
| indication for TLS/SSL connections. |
| |
| - Issue 20123: Fix pydoc.synopsis() for "binary" modules. |
| |
| - Issue #19834: Support unpickling of exceptions pickled by Python 2. |
| |
| - Issue #19781: ftplib now supports SSLContext.check_hostname and server name |
| indication for TLS/SSL connections. |
| |
| - Issue #19509: Add SSLContext.check_hostname to match the peer's certificate |

| constructor is given a str. Move the array module typecode documentation to |
| the docstring of the constructor. |

| What's New in Python 3.4.0 Beta 1? |
| ================================== |
| |
| Release date: 2013-11-24 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Use the repr of a module name in more places in import, especially |
| exceptions. |
| |
| - Issue #19619: str.encode, bytes.decode and bytearray.decode now use an |
| internal API to throw LookupError for known non-text encodings, rather |
| than attempting the encoding or decoding operation and then throwing a |
| TypeError for an unexpected output type. (The latter mechanism remains |
| in place for third party non-text encodings) |
| |
| - Issue #19183: Implement PEP 456 'secure and interchangeable hash algorithm'. |
| Python now uses SipHash24 on all major platforms. |
| |
| - Issue #12892: The utf-16* and utf-32* encoders no longer allow surrogate code |
| points (U+D800-U+DFFF) to be encoded. The utf-32* decoders no longer decode |
| byte sequences that correspond to surrogate code points. The surrogatepass |
| error handler now works with the utf-16* and utf-32* codecs. Based on |
| patches by Victor Stinner and Kang-Hao (Kenny) Lu. |
| |
| - Issue #17806: Added keyword-argument support for "tabsize" to |
| str/bytes.expandtabs(). |
| |
| - Issue #17828: Output type errors in str.encode(), bytes.decode() and |
| bytearray.decode() now direct users to codecs.encode() or codecs.decode() |
| as appropriate. |
| |
| - Issue #17828: The interpreter now attempts to chain errors that occur in |
| codec processing with a replacement exception of the same type that |
| includes the codec name in the error message. It ensures it only does this |
| when the creation of the replacement exception won't lose any information. |
| |
| - Issue #19466: Clear the frames of daemon threads earlier during the |
| Python shutdown to call objects destructors. So "unclosed file" resource |
| warnings are now corretly emitted for daemon threads. |
| |
| - Issue #19514: Deduplicate some _Py_IDENTIFIER declarations. |
| Patch by Andrei Dorian Duma. |
| |
| - Issue #17936: Fix O(n**2) behaviour when adding or removing many subclasses |
| of a given type. |
| |
| - Issue #19428: zipimport now handles errors when reading truncated or invalid |
| ZIP archive. |
| |
| - Issue #18408: Add a new PyFrame_FastToLocalsWithError() function to handle |
| exceptions when merging fast locals into f_locals of a frame. |
| PyEval_GetLocals() now raises an exception and return NULL on failure. |
| |
| - Issue #19369: Optimized the usage of __length_hint__(). |
| |
| - Issue #18603: Ensure that PyOS_mystricmp and PyOS_mystrnicmp are in the |
| Python executable and not removed by the linker's optimizer. |
| |
| - Issue #19306: Add extra hints to the faulthandler module's stack |
| dumps that these are "upside down". |
| |
| Library |

| - Issue #3158: doctest can now find doctests in functions and methods |
| written in C. |
| |
| - Issue #13477: Added command line interface to the tarfile module. |
| Original patch by Berker Peksag. |
| |
| - Issue #19674: inspect.signature() now produces a correct signature |
| for some builtins. |
| |
| - Issue #19722: Added opcode.stack_effect(), which |
| computes the stack effect of bytecode instructions. |
| |
| - Issue #19735: Implement private function ssl._create_stdlib_context() to |
| create SSLContext objects in Python's stdlib module. It provides a single |
| configuration point and makes use of SSLContext.load_default_certs(). |
| |
| - Issue #16203: Add re.fullmatch() function and regex.fullmatch() method, |
| which anchor the pattern at both ends of the string to match. |
| Original patch by Matthew Barnett. |
| |
| - Issue #13592: Improved the repr for regular expression pattern objects. |
| Based on patch by Hugo Lopes Tavares. |
| |
| - Issue #19641: Added the audioop.byteswap() function to convert big-endian |
| samples to little-endian and vice versa. |
| |
| - Issue #15204: Deprecated the 'U' mode in file-like objects. |
| |
| - Issue #17810: Implement PEP 3154, pickle protocol 4. |
| |
| - Issue #19668: Added support for the cp1125 encoding. |
| |
| - Issue #19689: Add ssl.create_default_context() factory function. It creates |
| a new SSLContext object with secure default settings. |
| |
| - Issue #19727: os.utime(..., None) is now potentially more precise |
| under Windows. |
| |
| - Issue #17201: ZIP64 extensions now are enabled by default. Patch by |
| William Mallard. |
| |
| - Issue #19292: Add SSLContext.load_default_certs() to load default root CA |
| certificates from default stores or system stores. By default the method |
| loads CA certs for authentication of server certs. |
| |
| - Issue #19673: Add pathlib to the stdlib as a provisional module (PEP 428). |
| |
| - Issue #16596: pdb in a generator now properly skips over yield and |
| yield from rather than stepping out of the generator into its |
| caller. (This is essential for stepping through asyncio coroutines.) |
| |
| - Issue #17916: Added dis.Bytecode.from_traceback() and |
| dis.Bytecode.current_offset to easily display "current instruction" |
| markers in the new disassembly API (Patch by Claudiu Popa). |
| |
| - Issue #19552: venv now supports bootstrapping pip into virtual environments |
| |
| - Issue #17134: Finalize interface to Windows' certificate store. Cert and |
| CRL enumeration are now two functions. enum_certificates() also returns |
| purpose flags as set of OIDs. |
| |
| - Issue #19555: Restore sysconfig.get_config_var('SO'), (and the distutils |
| equivalent) with a DeprecationWarning pointing people at $EXT_SUFFIX. |
| |
| - Issue #8813: Add SSLContext.verify_flags to change the verification flags |
| of the context in order to enable certification revocation list (CRL) |
| checks or strict X509 rules. |
| |
| - Issue #18294: Fix the zlib module to make it 64-bit safe. |

| |
| - Issue #19633: Fixed writing not compressed 16- and 32-bit wave files on |
| big-endian platforms. |
| |
| - Issue #18379: SSLSocket.getpeercert() returns CA issuer AIA fields, OCSP |
| and CRL distribution points. |
| |
| - Issue #18138: Implement cadata argument of SSLContext.load_verify_location() |
| to load CA certificates and CRL from memory. It supports PEM and DER |
| encoded strings. |
| |
| - Issue #18775: Add name and block_size attribute to HMAC object. They now |
| provide the same API elements as non-keyed cryptographic hash functions. |
| |
| - Issue #17276: MD5 as default digestmod for HMAC is deprecated. The HMAC |
| module supports digestmod names, e.g. hmac.HMAC('sha1'). |
| |
| - Issue #19449: in csv's writerow, handle non-string keys when generating the |
| error message that certain keys are not in the 'fieldnames' list. |
| |
| - Issue #13633: Added a new convert_charrefs keyword arg to HTMLParser that, |
| when True, automatically converts all character references. |
| |
| - Issue #2927: Added the unescape() function to the html module. |
| |

| |
| - Issue #19553: PEP 453 - "make install" and "make altinstall" now install or |

| - Issue #18810: Shift stat calls in importlib.machinery.FileFinder such that |
| the code is optimistic that if something exists in a directory named exactly |
| like the possible package being searched for that it's in actuality a |
| directory. |
| |
| - Issue #18416: importlib.machinery.PathFinder now treats '' as the cwd and |
| importlib.machinery.FileFinder no longer special-cases '' to '.'. This leads |
| to modules imported from cwd to now possess an absolute file path for |
| __file__ (this does not affect modules specified by path on the CLI but it |
| does affect -m/runpy). It also allows FileFinder to be more consistent by not |
| having an edge case. |
| |
| - Issue #4555: All exported C symbols are now prefixed with either |
| "Py" or "_Py". |

| |
| - Issue #19262: Initial check in of the 'asyncio' package (a.k.a. Tulip, |
| a.k.a. PEP 3156). There are no docs yet, and the PEP is slightly |
| out of date with the code. This module will have *provisional* status |
| in Python 3.4. |
| |
| - Issue #19276: Fixed the wave module on 64-bit big-endian platforms. |
| |
| - Issue #19266: Rename the new-in-3.4 ``contextlib.ignore`` context manager |
| to ``contextlib.suppress`` in order to be more consistent with existing |
| descriptions of that operation elsewhere in the language and standard |
| library documentation (Patch by Zero Piraeus). |
| |

| compressed streams. |
| |
| - Issue #19209: Remove import of copyreg from the os module to speed up |
| interpreter startup. stat_result and statvfs_result are now hard-coded to |
| reside in the os module. |
| |
| - Issue #19205: Don't import the 're' module in site and sysconfig module to |
| to speed up interpreter start. |
| |
| - Issue #9548: Add a minimal "_bootlocale" module that is imported by the |

| |
| - Issue #17839: base64.decodebytes and base64.encodebytes now accept any |

| |
| - Issue #14499: Fix several problems with OS X universal build support: |
| 1. ppc arch detection for extension module builds broke with Xcode 5 |
| 2. ppc arch detection in configure did not work on OS X 10.4 |
| 3. -sysroot and -arch flags were unnecessarily duplicated |
| 4. there was no obvious way to configure an intel-32 only build. |
| |
| - Issue #19019: Change the OS X installer build script to use CFLAGS instead |
| of OPT for special build options. By setting OPT, some compiler-specific |
| options like -fwrapv were overridden and thus not used, which could result |
| in broken interpreters when building with clang. |

| What's New in Python 3.4.0 Alpha 2? |
| =================================== |
| |
| Release date: 2013-09-09 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #18942: sys._debugmallocstats() output was damaged on Windows. |
| |
| - Issue #18571: Implementation of the PEP 446: file descriptors and file |
| handles are now created non-inheritable; add functions |
| os.get/set_inheritable(), os.get/set_handle_inheritable() and |
| socket.socket.get/set_inheritable(). |
| |
| - Issue #11619: The parser and the import machinery do not encode Unicode |
| filenames anymore on Windows. |
| |
| - Issue #18808: Non-daemon threads are now automatically joined when |
| a sub-interpreter is shutdown (it would previously dump a fatal error). |
| |
| - Remove support for compiling on systems without getcwd(). |
| |
| - Issue #18774: Remove last bits of GNU PTH thread code and thread_pth.h. |
| |
| - Issue #18771: Add optimization to set object lookups to reduce the cost |
| of hash collisions. The core idea is to inspect a second key/hash pair |
| for each cache line retrieved. |
| |
| - Issue #16105: When a signal handler fails to write to the file descriptor |
| registered with ``signal.set_wakeup_fd()``, report an exception instead |
| of ignoring the error. |
| |
| - Issue #18722: Remove uses of the "register" keyword in C code. |
| |
| - Issue #18667: Add missing "HAVE_FCHOWNAT" symbol to posix._have_functions. |

| |
| - Issue #17934: Add a clear() method to frame objects, to help clean up |
| expensive details (local variables) and break reference cycles. |
| |
| - Issue #18780: %-formatting codes %d, %i, and %u now treat int-subclasses |
| as int (displays value of int-subclass instead of str(int-subclass) ). |
| |
| Library |
| ------- |
| |
| - Issue #18808: Thread.join() now waits for the underlying thread state to |
| be destroyed before returning. This prevents unpredictable aborts in |
| Py_EndInterpreter() when some non-daemon threads are still running. |
| |
| - Issue #18458: Prevent crashes with newer versions of libedit. Its readline |
| emulation has changed from 0-based indexing to 1-based like gnu readline. |

| |
| - Issue #18882: Add threading.main_thread() function. |
| |

| a plain tuple. Patch by Claudiu Popa. |
| |
| - Issue #17487: The result of the wave getparams method now is pickleable again. |
| Patch by Claudiu Popa. |
| |
| - Issue #18756: os.urandom() now uses a lazily-opened persistent file |
| descriptor, so as to avoid using many file descriptors when run in |
| parallel from multiple threads. |
| |
| - Issue #18418: After fork(), reinit all threads states, not only active ones. |
| Patch by A. Jesse Jiryu Davis. |
| |

| |
| - Issue #16809: Tkinter's splitlist() and split() methods now accept Tcl_Obj |
| argument. |
| |
| - Issue #18324: set_payload now correctly handles binary input. This also |
| supersedes the previous fixes for #14360, #1717, and #16564. |
| |
| - Issue #18794: Add a fileno() method and a closed attribute to select.devpoll |
| objects. |

| - Issue #18178: Fix ctypes on BSD. dlmalloc.c was compiled twice which broke |
| malloc weak symbols. |
| |

| inside subjectAltName correctly. Formerly the module has used OpenSSL's |
| GENERAL_NAME_print() function to get the string represention of ASN.1 |
| strings for ``rfc822Name`` (email), ``dNSName`` (DNS) and |
| ``uniformResourceIdentifier`` (URI). |
| |

| |
| - Issue #18756: Improve error reporting in os.urandom() when the failure |
| is due to something else than /dev/urandom not existing (for example, |
| exhausting the file descriptor limit). |
| |
| - Issue #18673: Add O_TMPFILE to os module. O_TMPFILE requires Linux kernel |
| 3.11 or newer. It's only defined on system with 3.11 uapi headers, too. |

| as promised by hashlib's documentation. |
| |

| |
| - Issue #12015: The tempfile module now uses a suffix of 8 random characters |

| if methods have annotations; it now correctly displays the annotations. |
| |
| - Issue #18600: Added policy argument to email.message.Message.as_string, |
| and as_bytes and __bytes__ methods to Message. |
| |
| - Issue #18671: Output more information when logging exceptions occur. |

| existing directory caused mkstemp and related APIs to fail instead of |
| retrying. Report and fix by Vlad Shcherbina. |
| |
| - Issue #18920: argparse's default destination for the version action (-v, |
| --version) has also been changed to stdout, to match the Python executable. |

| test.support. Patch by Valerie Lambert. |
| |
| - Issue #12037: Fix test_email for desktop Windows. |
| |
| - Issue #15507: test_subprocess's test_send_signal could fail if the test |
| runner were run in an environment where the process inherited an ignore |
| setting for SIGINT. Restore the SIGINT handler to the desired |
| KeyboardInterrupt raising one during that test. |
| |
| - Issue #16799: Switched from getopt to argparse style in regrtest's argument |
| parsing. Added more tests for regrtest's argument parsing. |
| |
| - Issue #18792: Use "127.0.0.1" or "::1" instead of "localhost" as much as |
| possible, since "localhost" goes through a DNS lookup under recent Windows |
| versions. |
| |
| IDLE |
| ---- |

| shipped in OS X 10.6 and later releases. |
| |
| Tools/Demos |
| ----------- |
| |
| - Issue #18922: Now The Lib/smtpd.py and Tools/i18n/msgfmt.py scripts write |

| winreg.QueryValueEx that may have been returning truncated values. |
| |
