| Release date: 2014-09-22 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #22258: Fix the the internal function set_inheritable() on Illumos. |
| This platform exposes the function ``ioctl(FIOCLEX)``, but calling it fails |

| now falls back to the slower ``fcntl()`` (``F_GETFD`` and then ``F_SETFD``). |
| |
| - Issue #21669: With the aid of heuristics in SyntaxError.__init__, the |
| parser now attempts to generate more meaningful (or at least more search |

| and "or" operators. |

| maintenance release, but we use a trick to remain backward compatible with |
| 3.4.0/1. |

| with non-standard cookie handling in some Web browsers. Reported by |
| Sergey Bobrov. |
| |

| response is received. Patch by Martin Panter. |
| |

| shrunk. Original patches by Jan Kanis and Lita Cho. |

| caused by mutation of the waiters queue without holding the lock. Patch |

| |
| - Issue #19407: New package installation and distribution guides based on |

| 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_*()' |

| =============================================== |
| |
| 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. |

| 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 |

| |
| - Issue #19920: Added tests for TarFile.list(). Based on patch by Vajrasky Kok. |
| |

| 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. |

| 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() |

| 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(). |

| 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. |
| |

| 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 |

| 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. |

| billion characters) input strings in _Py_dg_strtod. |
| |
| Library |
| ------- |

| - Issue #20154: Deadlock in asyncio.StreamReader.readexactly(). |
| |
| - 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. |

| 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". |
| |

| |
| - 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 #19727: os.utime(..., None) is now potentially more precise |
| under Windows. |
| |

| |
| - 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.) |
| |

| dis.Bytecode.current_offset to easily display "current instruction" |
| markers in the new disassembly API (Patch by Claudiu Popa). |

| 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'). |
| |

| on a system with SO_REUSEPORT defined in the headers but run on a system |
| with an OS kernel that does not support that reasonably new socket option. |
| |
| - Fix compilation error under gcc of the ctypes module bundled libffi for arm. |

| |
| - Issue #19378: the "line_offset" parameter in the new "dis.get_instructions" |
| API has been renamed to "first_line" (and the default value and usage |
| changed accordingly). This should reduce confusion with the more common use |
| of "offset" in the dis docs to refer to bytecode offsets. |
| |
| - Issue #18678: Corrected spwd struct member names in spwd module: |
| sp_nam->sp_namp, and sp_pwd->sp_pwdp. The old names are kept as extra |

| |
| Release date: 2013-10-20 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #19301: Give classes and functions that are explicitly marked global a |
| global qualname. |
| |
| - Issue #19279: UTF-7 decoder no longer produces illegal strings. |
| |
| - Issue #16612: Add "Argument Clinic", a compile-time preprocessor for |
| C files to generate argument parsing code. (See PEP 436.) |
| |
| - 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 #19219: Speed up marshal.loads(), and make pyc files slightly |
| (5% to 10%) smaller. |
| |

| |
| - Issue #16742: The result of the C callback PyOS_ReadlineFunctionPointer must |
| now be a string allocated by PyMem_RawMalloc() or PyMem_RawRealloc() (or NULL |
| if an error occurred), instead of a string allocated by PyMem_Malloc() or |
| PyMem_Realloc(). |
| |
| - Issue #19199: Remove ``PyThreadState.tick_counter`` field |
| |
| - Fix macro expansion of _PyErr_OCCURRED(), and make sure to use it in at |
| least one place so as to avoid regressions. |
| |
| - Issue #19087: Improve bytearray allocation in order to allow cheap popping |
| of data at the front (slice deletion). |
| |
| - Issue #19014: memoryview.cast() is now allowed on zero-length views. |
| |
| - Issue #18690: memoryview is now automatically registered with |
| collections.abc.Sequence |

| - 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 |

| 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 |

| compressed streams. |
| |

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

| when necessary. Patch by Oscar Benjamin. |
| |
| - Issue #5845: In site.py, only load readline history from ~/.python_history |

| 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. |

| ----------------- |
| |
| - 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 |

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

| |
| - 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. |

| |
| What's New in Python 3.3.0 Release Candidate 3? |
| =============================================== |
| |
| *Release date: 23-Sep-2012* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #15900: Fix reference leak in `PyUnicode_TranslateCharmap()`. |

| |
| - Fixes for a few crash and memory leak regressions found by Coverity. |
| |
| Library |
| ------- |
| |
| - Issue #15882: Change `_decimal` to accept any coefficient tuple when |
| constructing infinities. This is done for backwards compatibility with |
| decimal.py: Infinity coefficients are undefined in _decimal (in accordance |
| with the specification). |

| What's New in Python 3.3.0 Release Candidate 2? |
| =============================================== |
| |
| *Release date: 09-Sep-2012* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #13992: The trashcan mechanism is now thread-safe. This eliminates |
| sporadic crashes in multi-thread programs when several long deallocator chains |
| ran concurrently and involved subclasses of built-in container types. |
| |
| - Issue #15784: Modify `OSError`.__str__() to better distinguish between errno |
| error numbers and Windows error numbers. |
| |
| - Issue #15781: Fix two small race conditions in import's module locking. |
| |
| Library |
| ------- |
| |
| - Issue #17158: Add 'symbols' to help() welcome message; clarify |
| 'modules spam' messages. |

| |
| - Issue #10650: Deprecate the watchexp parameter of the `Decimal.quantize()` |
| 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 |
| ----- |
| |
| - Issue #15822: Really ensure 2to3 grammar pickles are properly installed |

| Patch by Chris Rebert. |
| |
| - Create a 'Concurrent Execution' section in the docs, and split up the |
| 'Optional Operating System Services' section to use a more user-centric |

| |
| 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 #14928: Fix importlib bootstrap issues by using a custom executable |

| 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. |
| |

| 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 #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 |

| 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 |

| 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. |

| format string that contains positional fields. Initial patch by |
| Julian Berman. |

| 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. |

| the __dir__() methods of those types. |
| |
| - Issue #5715: In socketserver, close the server socket in the child process. |

| they try to take the GIL. |
| |
| - Issue #9756: When calling a method descriptor or a slot wrapper descriptor, |
| 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_* |

| depending on heap usage). |
| |

| |
| - Issue #11432: A bug was introduced in subprocess.Popen on posix systems with |

| file descriptor would raise an exception. webbrowser.open would fail. fixed. |
| |
| - Issue #9856: Change object.__format__ with a non-empty format string |
| to be a DeprecationWarning. In 3.2 it was a PendingDeprecationWarning. |
| In 3.4 it will be a TypeError. |
| |
| - Issue #11244: The peephole optimizer is now able to constant-fold |
| arbitrarily complex expressions. This also fixes a 3.2 regression where |

| - 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 #13960: HTMLParser is now able to handle broken comments when |

| |
| - Issue #13845: On Windows, time.time() now uses GetSystemTimeAsFileTime() |
| instead of ftime() to have a resolution of 100 ns instead of 1 ms (the clock |
| accuracy is between 0.5 ms and 15 ms). |
| |
| - Issue #13846: Add time.monotonic(), monotonic clock. |
| |

| 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). |

| 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. |

| 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 |

| 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 #12407: Explicitly skip test_capi.EmbeddingTest under Windows. |
| |
| - Issue #12400: regrtest -W doesn't rerun the tests twice anymore, but captures |

| 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 |
