    Python News
    What's New in Python 2.7.11?
    *Release date: 2015-12-05*
    - Issue #25624: ZipFile now always writes a ZIP_STORED header for directory
      entries.  Patch by Dingyuan Wang.
    What's New in Python 2.7.11 release candidate 1?
    *Release date: 2015-11-21*
    Core and Builtins
    - Issue #25678: Avoid buffer overreads when int(), long(), float(), and
      compile() are passed buffer objects.  These objects are not necessarily
      terminated by a null byte, but the functions assumed they were.
    - Issue #25388: Fixed tokenizer hang when processing undecodable source code
      with a null byte.
    - Issue #22995: Default implementation of __reduce__ and __reduce_ex__ now
      rejects builtin types with not defined __new__.
    - Issue #7267: format(int, 'c') now raises OverflowError when the argument is
      not in range(0, 256).
    - Issue #24806: Prevent builtin types that are not allowed to be subclassed from
      being subclassed through multiple inheritance.
    - Issue #24848: Fixed a number of bugs in UTF-7 decoding of misformed data.
    - Issue #25003: os.urandom() doesn't use getentropy() on Solaris because
      getentropy() is blocking, whereas os.urandom() should not block. getentropy()
      is supported since Solaris 11.3.
    - Issue #21167: NAN operations are now handled correctly when python is
      compiled with ICC even if -fp-model strict is not specified.
    - Issue #24467: Fixed possible buffer over-read in bytearray. The bytearray
      object now always allocates place for trailing null byte and it's buffer now
      is always null-terminated.
    - Issue #19543: encode() and decode() methods and constructors of str,
      unicode and bytearray classes now emit deprecation warning for known
      non-text encodings when Python is ran with the -3 option.
    - Issue #24115: Update uses of PyObject_IsTrue(), PyObject_Not(),
      PyObject_IsInstance(), PyObject_RichCompareBool() and _PyDict_Contains()
      to check for and handle errors correctly.
    - Issue #4753: On compilers where it is supported, use "computed gotos" for
      bytecode dispatch in the interpreter. This improves interpretation
    - Issue #22939: Fixed integer overflow in iterator object.  Original patch by
      Clement Rouault.
    - Issue #24102: Fixed exception type checking in standard error handlers.
    - Issue #10128: backport issue #10845's mitigation of incompatibilities between
      the multiprocessing module and directory and zipfile execution.
      Multiprocessing on Windows will now automatically skip rerunning __main__ in
      spawned processes, rather than failing with AssertionError.
    - Issue #25578: Fix (another) memory leak in SSLSocket.getpeercer().
    - Issue #25590: In the Readline completer, only call getattr() once per
    - Issue #25530: Disable the vulnerable SSLv3 protocol by default when creating
    - Issue #25569: Fix memory leak in SSLSocket.getpeercert().
    - Issue #7759: Fixed the mhlib module on filesystems that doesn't support
      link counting for directories.
    - Issue #892902: Fixed pickling recursive objects.
    - Issue #18010: Fix the pydoc GUI's search function to handle exceptions
      from importing packages.
    - Issue #25515: Always use os.urandom as a source of randomness in uuid.uuid4.
    - Issue #21827: Fixed textwrap.dedent() for the case when largest common
      whitespace is a substring of smallest leading whitespace.
      Based on patch by Robert Li.
    - Issue #21709: Fix the logging module to not depend upon __file__ being set
      properly to get the filename of its caller from the stack.  This allows it
      to work if run in a frozen or embedded environment where the module's
      .__file__ attribute does not match its code object's .co_filename.
    - Issue #25319: When threading.Event is reinitialized, the underlying condition
      should use a regular lock rather than a recursive lock.
    - Issue #25232: Fix CGIRequestHandler to split the query from the URL at the
      first question mark (?) rather than the last. Patch from Xiang Zhang.
    - Issue #24657: Prevent CGIRequestHandler from collapsing slashes in the
      query part of the URL as if it were a path. Patch from Xiang Zhang.

      accept the self keyword argument.
    - Issue #25203: Failed readline.set_completer_delims() no longer left the

    - Issue #25135: Make deque_clear() safer by emptying the deque before clearing.
      This helps avoid possible reentrancy issues.
    - Issue #24684: socket.socket.getaddrinfo() now calls
      PyUnicode_AsEncodedString() instead of calling the encode() method of the
      host, to handle correctly custom unicode string with an encode() method
      which doesn't return a byte string. The encoder of the IDNA codec is now
      called directly instead of calling the encode() method of the string.
    - Issue #24982: shutil.make_archive() with the "zip" format now adds entries
      for directories (including empty directories) in ZIP file.
    - Issue #17849: Raise a sensible exception if an invalid response is
      received for a HTTP tunnel request, as seen with some servers that
      do not support tunnelling.  Initial patch from Cory Benfield.

    - Issue #24634: Importing uuid should not try to load libc on Windows

    - Issue #17527: Add PATCH to wsgiref.validator. Patch from Luca Sbardella.
    - Issue #24613: Calling array.fromstring() with self is no longer allowed
      to prevent the use-after-free error.  Patch by John Leitch.
    - Issue #24708: Fix possible integer overflow in strop.replace().
    - Issue #24620: Random.setstate() now validates the value of state last element.
    - Issue #13938: 2to3 converts StringTypes to a tuple. Patch from Mark Hammond.

      tuple.  Fixed possible memory leak.
    - Issue #24481: Fix possible memory corruption with large profiler info strings
      in hotshot.
    - Issue #24489: ensure a previously set C errno doesn't disturb cmath.polar().
    - Issue #19543: io.TextIOWrapper (and hence io.open()) now uses the internal
      codec marking system added to emit deprecation warning for known non-text
      encodings at stream construction time when Python is ran with the -3 option.
    - Issue #24264: Fixed buffer overflow in the imageop module.

      Original patch by David Moore.
    - Issue #22095: Fixed HTTPConnection.set_tunnel with default port.  The port

      to their regular dict counterparts.
    - Issue #22107: tempfile.gettempdir() and tempfile.mkdtemp() now try again
      when a directory with the chosen name already exists on Windows as well as

      Formatting unicode warning in the file with the path containing non-ascii
      characters no longer fails with UnicodeErrror.
    - Issue #24134: Reverted issue #24134 changes.
    - Issue 15348: Stop the debugger engine (normally in a user process)
      before closing the debugger window (running in the IDLE process).
      This prevents the RuntimeErrors that were being caught and ignored.
    - Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
      debugger is active (15347); b) closing the debugger with the [X] button
      (15348); and c) activating the debugger when already active (24455).
      The patch by Mark Roseman does this by making two changes.
      1. Suspend and resume the gui.interaction method with the tcl vwait
      mechanism intended for this purpose (instead of root.mainloop & .quit).
     2. In gui.run, allow any existing interaction to terminate first.

    - Change 'The program' to 'Your program' in an IDLE 'kill program?' message
     to make it clearer that the program referred to is the currently running
     user program, not IDLE itself.

     Patch by Mark Roseman.

    - Issue #25313: Change the handling of new built-in text color themes to better
     address the compatibility problem introduced by the addition of IDLE Dark.
     Consistently use the revised idleConf.CurrentTheme everywhere in idlelib.

    - Issue #24782: Extension configuration is now a tab in the IDLE Preferences
     dialog rather than a separate dialog.   The former tabs are now a sorted
     list.  Patch by Mark Roseman.

    - Issue #22726: Re-activate the config dialog help button with some content
     about the other buttons and the new IDLE Dark theme.

    - Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme.
     It is more or less IDLE Classic inverted, with a cobalt blue background.
     Strings, comments, keywords, ... are still green, red, orange, ... .
     To use it with IDLEs released before November 2015, hit the
     'Save as New Custom Theme' button and enter a new name,
     such as 'Custom Dark'.  The custom theme will work with any IDLE
     release, and can be modified.

    - Issue #25224: README.txt is now an idlelib index for IDLE developers and
     curious users.  The previous user content is now in the IDLE doc chapter.

     Settings -> Custom Highlighting.  Original patch by Mark Roseman.

     background, as configured by users, on all systems.  Found items are now
     always highlighted on Windows.  Initial patch by Mark Roseman.

     Patch by Mark Roseman.

    - Issue #25173: Associate tkinter messageboxes with a specific widget.

    - Issue #25198: Enhance the initial html viewer now used for Idle Help.
     * Properly indent fixed-pitch text (patch by Mark Roseman).
     * Give code snippet a very Sphinx-like light blueish-gray background.
     * Re-use initial width and height set by users for shell and editor.
     * When the Table of Contents (TOC) menu is used, put the section header
     at the top of the screen.

    - Issue #25225: Condense and rewrite Idle doc section on text colors.

    - Issue #21995: Explain some differences between IDLE and console Python.

    - Issue #22820: Explain need for *print* when running file from Idle editor.

    - Issue #25199: Idle: add synchronization comments for future maintainers.

    - Issue #16893: Replace help.txt with help.html for Idle doc display.
     The new idlelib/help.html is rstripped Doc/build/html/library/idle.html.
     It looks better than help.txt and will better document Idle as released.
     The tkinter html viewer that works for this file was written by Mark Roseman.
     The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated.

    - Issue #24199: Deprecate unused idlelib.idlever with possible removal in 3.6.

    - Issue #24790: Remove extraneous code (which also create 2 & 3 conflicts).

    - Issue #23672: Allow Idle to edit and run files with astral chars in name.
     Patch by Mohd Sanad Zaki Rizvi.

    - Issue 24745: Idle editor default font. Switch from Courier to
     platform-sensitive TkFixedFont.  This should not affect current customized

     a test run is no longer marked as a failure if all tests succeed when

    - PCbuild\rt.bat now accepts an unlimited number of arguments to pass along
     to regrtest.py.  Previously there was a limit of 9.
