What's New in Python 3.2 Release Candidate 2?
|
|
=============================================
|
|
|
|
*Release date: XX-Jan-2011*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #10451: memoryview objects could allow to mutate a readable buffer.
|
|
Initial patch by Ross Lagerwall.
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #10983: Fix several bugs making tunnel requests in http.client.
|
|
|
|
- Issue #10955: zipimport uses ASCII encoding instead of cp497 to decode
|
|
filenames, at bootstrap, if the codec registry is not ready yet. It is still
|
|
possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
|
|
for all file entries in the ZIP file.
|
|
|
|
- Issue #10949: Improved robustness of rotating file handlers.
|
|
|
|
- Issue #10955: Fix a potential crash when trying to mmap() a file past its
|
|
length. Initial patch by Ross Lagerwall.
|
|
|
|
- Issue #10898: Allow compiling the posix module when the C library defines
|
|
a symbol named FSTAT.
|
|
|
|
- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
|
|
encoding. This is the preferred encoding of PEP 3333 and the base encoding
|
|
of HTTP 1.1.
|
|
|
|
- To match the behaviour of HTTP server, the HTTP client library now also
|
|
encodes headers with iso-8859-1 (latin1) encoding. It was already doing
|
|
that for incoming headers which makes this behaviour now consistent in
|
|
both incoming and outgoing direction.
|
|
|
|
|
|
What's New in Python 3.2 Release Candidate 1
|
|
============================================
|
|
|
|
*Release date: 16-Jan-2011*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #10889: range indexing and slicing now works correctly on ranges with
|
|
a length that exceeds sys.maxsize.
|
|
|
|
- Issue #10892: Don't segfault when trying to delete __abstractmethods__ from a
|
|
class.
|
|
|
|
- Issue #8020: Avoid a crash where the small objects allocator would read
|
|
non-Python managed memory while it is being modified by another thread. Patch
|
|
by Matt Bandy.
|
|
|
|
- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
|
|
io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
|
|
translates newlines (\r\n => \n).
|
|
|
|
- Remove buffer API from stable ABI for now, see #10181.
|
|
|
|
- Issue #8651: PyArg_Parse*() functions raise an OverflowError if the file
|
|
doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int
|
|
(length bigger than 2^31-1 bytes).
|
|
|
|
- Issue #9015, #9611: FileIO.readinto(), FileIO.write(), os.write() and
|
|
stdprinter.write() clamp the length to 2^31-1 on Windows.
|
|
|
|
- Issue #8278: On Windows and with a NTFS filesystem, os.stat() and os.utime()
|
|
can now handle dates after 2038.
|
|
|
|
- Issue #10780: PyErr_SetFromWindowsErrWithFilename() and
|
|
PyErr_SetExcFromWindowsErrWithFilename() decode the filename from the
|
|
filesystem encoding instead of UTF-8.
|
|
|
|
- Issue #10779: PyErr_WarnExplicit() decodes the filename from the filesystem
|
|
encoding instead of UTF-8.
|
|
|
|
- Add sys.flags attribute for the new -q command-line option.
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #10916: mmap should not segfault when a file is mapped using 0 as length
|
|
and a non-zero offset, and an attempt to read past the end of file is made
|
|
(IndexError is raised instead). Patch by Ross Lagerwall.
|
|
|
|
- Issue #10907: Warn OS X 10.6 IDLE users to use ActiveState Tcl/Tk 8.5, rather
|
|
than the currently problematic Apple-supplied one, when running with the
|
|
64-/32-bit installer variant.
|
|
|
|
- Issue #4953: cgi.FieldStorage and cgi.parse() parse the request as bytes, not
|
|
as unicode, and accept binary files. Add encoding and errors attributes to
|
|
cgi.FieldStorage. Patch written by Pierre Quentel (with many inputs by Glenn
|
|
Linderman).
|
|
|
|
- Add encoding and errors arguments to urllib.parse_qs() and urllib.parse_qsl().
|
|
|
|
- Issue #10899: No function type annotations in the standard library. Removed
|
|
function type annotations from _pyio.py.
|
|
|
|
- Issue #10875: Update Regular Expression HOWTO; patch by 'SilentGhost'.
|
|
|
|
- Issue #10872: The repr() of TextIOWrapper objects now includes the mode
|
|
if available.
|
|
|
|
- Issue #10869: Fixed bug where ast.increment_lineno modified the root node
|
|
twice.
|
|
|
|
- Issue #5871: email.header.Header.encode now raises an error if any
|
|
continuation line in the formatted value has no leading white space and looks
|
|
like a header. Since Generator uses Header to format all headers, this check
|
|
is made for all headers in any serialized message at serialization time. This
|
|
provides protection against header injection attacks.
|
|
|
|
- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially
|
|
private by renaming it to ``_GeneratorContextManager``.
|
|
|
|
- Issue #10042: Fixed the total_ordering decorator to handle cross-type
|
|
comparisons that could lead to infinite recursion.
|
|
|
|
- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
|
|
non-ASCII bytes (parsed by a Bytes Parser) when doing conversion to 7bit-clean
|
|
presentation, instead of replacing them with ?s.
|
|
|
|
- email.header.Header was incorrectly encoding folding white space when
|
|
rfc2047-encoding header values with embedded newlines, leaving them without
|
|
folding whitespace. It now uses the continuation_ws, as it does for
|
|
continuation lines that it creates itself.
|
|
|
|
- Issue #1777412, #10827: Changed the rules for 2-digit years. The
|
|
time.asctime(), time.ctime() and time.strftime() functions will now format
|
|
any year when ``time.accept2dyear`` is False and will accept years >= 1000
|
|
otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
|
|
supported by the OS. With Visual Studio or on Solaris, the year is limited to
|
|
the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
|
|
|
|
- Issue #7858: Raise an error properly when os.utime() fails under Windows
|
|
on an existing file.
|
|
|
|
- Issue #3839: wsgiref should not override a Content-Length header set by
|
|
the application. Initial patch by Clovis Fabricio.
|
|
|
|
- Issue #10492: bdb.Bdb.run() only traces the execution of the code, not the
|
|
compilation (if the input is a string).
|
|
|
|
- Issue #7995: When calling accept() on a socket with a timeout, the returned
|
|
socket is now always blocking, regardless of the operating system.
|
|
|
|
- Issue #10756: atexit normalizes the exception before displaying it. Patch by
|
|
Andreas Stührk.
|
|
|
|
- Issue #10790: email.header.Header.append's charset logic now works correctly
|
|
for charsets whose output codec is different from its input codec.
|
|
|
|
- Issue #10819: SocketIO.name property returns -1 when its closed, instead of
|
|
raising a ValueError, to fix repr().
|
|
|
|
- Issue #8650: zlib.compress() and zlib.decompress() raise an OverflowError if
|
|
the input buffer length doesn't fit into an unsigned int (length bigger than
|
|
2^32-1 bytes).
|
|
|
|
- Issue #6643: Reinitialize locks held within the threading module after fork to
|
|
avoid a potential rare deadlock or crash on some platforms.
|
|
|
|
- Issue #10806, issue #9905: Fix subprocess pipes when some of the standard file
|
|
descriptors (0, 1, 2) are closed in the parent process. Initial patch by Ross
|
|
Lagerwall.
|
|
|
|
- `unittest.TestCase` can be instantiated without a method name; for simpler
|
|
exploration from the interactive interpreter.
|
|
|
|
- Issue #10798: Reject supporting concurrent.futures if the system has too
|
|
few POSIX semaphores.
|
|
|
|
- Issue #10807: Remove base64, bz2, hex, quopri, rot13, uu and zlib codecs from
|
|
the codec aliases. They are still accessible via codecs.lookup().
|
|
|
|
- Issue #10801: In zipfile, support different encodings for the header and the
|
|
filenames.
|
|
|
|
- Issue #6285: IDLE no longer crashes on missing help file; patch by Scott
|
|
David Daniels.
|
|
|
|
- Fix collections.OrderedDict.setdefault() so that it works in subclasses that
|
|
define __missing__().
|
|
|
|
- Issue #10786: unittest.TextTestRunner default stream no longer bound at import
|
|
time. `sys.stderr` now looked up at instantiation time. Fix contributed by
|
|
Mark Roddy.
|
|
|
|
- Issue #10753: Characters ';','=' and ',' in the PATH_INFO environment variable
|
|
won't be quoted when the URI is constructed by the wsgiref.util 's request_uri
|
|
method. According to RFC 3986, these characters can be a part of params in
|
|
PATH component of URI and need not be quoted.
|
|
|
|
- Issue #10738: Fix webbrowser.Opera.raise_opts.
|
|
|
|
- Issue #9824: SimpleCookie now encodes , and ; in values to cater to how
|
|
browsers actually parse cookies.
|
|
|
|
- Issue #9333: os.symlink now available regardless of user privileges. The
|
|
function now raises OSError on Windows >=6.0 when the user is unable to create
|
|
symbolic links. XP and 2003 still raise NotImplementedError.
|
|
|
|
- Issue #10783: struct.pack() no longer implicitly encodes unicode to UTF-8.

|
|
- Issue #10626: test_logging now preserves logger disabled states.
|
|
|
|
- Issue #10774: test_logging now removes temp files created during tests.
|
|
|
|
- Issue #5258/#10642: if site.py encounters a .pth file that generates an error,
|
|
it now prints the filename, line number, and traceback to stderr and skips
|
|
the rest of that individual file, instead of stopping processing entirely.
|
|
|
|
- Issue #10763: subprocess.communicate() closes stdout and stderr if both are
|
|
pipes (bug specific to Windows).
|
|
|
|
- Issue #1693546: fix email.message RFC 2231 parameter encoding to be in better
|
|
compliance (no "s around encoded values).
|
|
|
|
- Improved the diff message in the unittest module's assertCountEqual().
|
|
|
|
- Issue #1155362: email.utils.parsedate_tz now handles a missing space before
|
|
the '-' of a timezone field as well as before a '+'.

|
C-API
|
|
-----
|
|
|
|
- Issue #10913: Deprecate misleading functions PyEval_AcquireLock() and
|
|
PyEval_ReleaseLock(). The thread-state aware APIs should be used instead.
|
|
|
|
- Issue #10333: Remove ancient GC API, which has been deprecated since Python
|
|
2.2.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Issue #10843: Update third-party library versions used in OS X 32-bit
|
|
installer builds: bzip2 1.0.6, readline 6.1.2, SQLite 3.7.4 (with FTS3/FTS4
|
|
and RTREE enabled), and ncursesw 5.5 (wide-char support enabled).
|
|
|
|
- Issue #10820: Fix OS X framework installs to support version-specific
|
|
scripts (#10679).
|
|
|
|
- Issue #7716: Under Solaris, don't assume existence of /usr/xpg4/bin/grep in
|
|
the configure script but use $GREP instead. Patch by Fabian Groffen.

- Issue #10475: Don't hardcode compilers for LDSHARED/LDCXXSHARED on NetBSD
|
|
and DragonFly BSD. Patch by Nicolas Joly.
|
|
|
|
- Issue #10679: The "idle", "pydoc" and "2to3" scripts are now installed with
|
|
a version-specific suffix on "make altinstall".
|
|
|
|
- Issue #10655: Fix the build on PowerPC on Linux with GCC when building with
|
|
timestamp profiling (--with-tsc): the preprocessor test for the PowerPC
|
|
support now looks for "__powerpc__" as well as "__ppc__": the latter seems to
|
|
only be present on OS X; the former is the correct one for Linux with GCC.
|
|
|
|
Tools/Demos
|
|
-----------
|
|
|
|
- Issue #10843: Install the Tools directory on OS X in the applications Extras
|
|
(/Applications/Python 3.n/Extras/) where the Demo directory had previous been
|
|
installed.
|
|

|
|
demos have been removed, others integrated in documentation or a new
|
|
Tools/demo subdirectory.

|
|

- Issue #10499: configparser supports pluggable interpolation handlers. The
|
|
default classic interpolation handler is called BasicInterpolation. Another
|
|
interpolation handler added (ExtendedInterpolation) which supports the syntax
|
|
used by zc.buildout (e.g. interpolation between sections).
|
|
|
|
- configparser: the SafeConfigParser class has been renamed to ConfigParser.
|
|
The legacy ConfigParser class has been removed but its interpolation mechanism
|
|
is still available as LegacyInterpolation.

accept vars and default arguments just like get() does.
|
|
|
|
- Issue #9452: configparser supports reading from strings and dictionaries
|
|
(thanks to the mapping protocol API, the latter can be used to copy data
|
|
between parsers).
|
|
|
|
- configparser: accepted INI file structure is now customizable, including
|
|
comment prefixes, name of the DEFAULT section, empty lines in multiline
|
|
values, and indentation.

|
C-API
|
|
-----
|
|
|
|
- Issue #10557: Added a new API function, PyUnicode_TransformDecimalToASCII(),
|
|
which transforms non-ASCII decimal digits in a Unicode string to their ASCII
|
|
equivalents.
|
|
|
|
- Issue #9518: Extend the PyModuleDef_HEAD_INIT macro to explicitly
|
|
zero-initialize all fields, fixing compiler warnings seen when building
|
|
extension modules with gcc with "-Wmissing-field-initializers" (implied by
|
|
"-W").
|
|
|
|
- Issue #10255: Fix reference leak in Py_InitializeEx(). Patch by Neil
|
|
Schemenauer.

Tests
|
|
-----
|
|
|
|
- regrtest.py once again ensures the test directory is removed from sys.path
|
|
when it is invoked directly as the __main__ module.
|
|
|
|
- `python -m test` can be used to run the test suite as well as `python -m
|
|
test.regrtest`.
|
|
|
|
- Do not fail test_socket when the IP address of the local hostname cannot be
|
|
looked up.

What's New in Python 3.2 Alpha 4?
|
|
=================================
|
|
|
|
*Release date: 13-Nov-2010*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #10372: Import the warnings module only after the IO library is
|
|
initialized, so as to avoid bootstrap issues with the '-W' option.
|
|
|
|
- Issue #10293: Remove obsolete field in the PyMemoryView structure, unused
|
|
undocumented value PyBUF_SHADOW, and strangely-looking code in
|
|
PyMemoryView_GetContiguous.
|
|
|
|
- Issue #6081: Add str.format_map(), similar to ``str.format(**mapping)``.
|
|
|
|
- If FileIO.__init__ fails, close the file descriptor.
|
|
|
|
- Issue #10221: dict.pop(k) now has a key error message that includes the
|
|
missing key (same message d[k] returns for missing keys).
|
|
|
|
- Issue #5437: A preallocated MemoryError instance should not keep traceback
|
|
data (including local variables caught in the stack trace) alive infinitely.
|
|
|
|
- Issue #10186: Fix the SyntaxError caret when the offset is equal to the length
|
|
of the offending line.
|
|
|
|
- Issue #10089: Add support for arbitrary -X options on the command line. They
|
|
can be retrieved through a new attribute ``sys._xoptions``.
|
|
|
|
- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
|
|
the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
|
|
variable is not set, the locale encoding is ISO-8859-1, whereas most programs
|
|
(including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
|
|
encoding and to encode command line arguments on this OS.
|
|
|
|
- Issue #9713, #10114: Parser functions (e.g. PyParser_ASTFromFile) expect
|
|
filenames encoded to the filesystem encoding with the surrogateescape error
|
|
handler (to support undecodable bytes), instead of UTF-8 in strict mode.
|
|
|
|
- Issue #9997: Don't let the name "top" have special significance in scope
|
|
resolution.
|
|
|
|
- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding its value as
|
|
the default 512 when compiling on AIX.
|
|
|
|
- Use locale encoding instead of UTF-8 to encode and decode filenames if
|
|
Py_FileSystemDefaultEncoding is not set.
|
|
|
|
- Issue #10095: fp_setreadl() doesn't reopen the file, instead reuse the file
|
|
descriptor.
|
|
|
|
- Issue #9418: Moved private string methods ``_formatter_parser`` and
|
|
``_formatter_field_name_split`` into a new ``_string`` module.
|
|
|
|
- Issue #9992: Remove PYTHONFSENCODING environment variable.
|
|
|

|
|
there are non-base64 alphabet characters in the input.

|
|
tokenize module and prevents leaking of private names through ``import *``.
|
|
|
|
- Issue #4471: Properly shutdown socket in IMAP.shutdown(). Patch by Lorenzo
|
|
M. Catucci.
|
|
|
|
- Fix IMAP.login() to work properly.
|
|
|
|
- Issue #9244: multiprocessing pool worker processes could terminate
|
|
unexpectedly if the return value of a task could not be pickled. Only the
|
|
``repr`` of such errors are now sent back, wrapped in an
|
|
``MaybeEncodingError`` exception.
|
|
|
|
- Issue #9244: The ``apply_async()`` and ``map_async()`` methods of
|
|
``multiprocessing.Pool`` now accepts a ``error_callback`` argument. This can
|
|
be a callback with the signature ``callback(exc)``, which will be called if
|
|
the target raises an exception.
|
|
|
|
- Issue #10022: The dictionary returned by the ``getpeercert()`` method of SSL
|
|
sockets now has additional items such as ``issuer`` and ``notBefore``.

|
|
tokenize.detect_encoding() and open it in read only mode.

|
|
method send_message to send an email.message.Message object.
|
|
|
|
- Issue #6011: sysconfig and distutils.sysconfig use the surrogateescape error
|
|
handler to parse the Makefile file. Avoid a UnicodeDecodeError if the source
|
|
code directory name contains a non-ASCII character and the locale encoding is
|
|
ASCII.
|
|
|
|
- Issue #10329: The trace module writes reports using the input Python script
|
|
encoding, instead of the locale encoding. Patch written by Alexander
|
|
Belopolsky.
|
|
|
|
- Issue #10126: Fix distutils' test_build when Python was built with

|
|
unpickling them produced nonsensical results.
|

|
|
environment better, and to correct unicode environment values for WSGI 1.0.1.
|
|
|
|
- Issue #10281: nntplib now returns None for absent fields in the OVER/XOVER
|
|
response, instead of raising an exception.
|
|
|
|
- wsgiref now implements and validates PEP 3333, rather than an experimental
|
|
extension of PEP 333. (Note: earlier versions of Python 3.x may have
|
|
incorrectly validated some non-compliant applications as WSGI compliant; if
|
|
your app validates with Python <3.2b1+, but not on this version, it is likely
|
|
the case that your app was not compliant.)
|
|
|
|
- Issue #10280: NNTP.nntp_version should reflect the highest version advertised
|
|
by the server.

|
|
parameter had been reduced.
|
|

not correct, change is made to raise a URLError when a remote host is tried to
|
|
access via file:// scheme.
|
|
|
|
- Issue #1710703: Write structures for an empty ZIP archive when a ZipFile is

What's New in Python 3.2 Alpha 3?
|
|
=================================
|
|
|
|
*Release date: 09-Oct-2010*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #10068: Global objects which have reference cycles with their module's
|
|
dict are now cleared again. This causes issue #7140 to appear again.
|
|
|
|
- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
|
|
encodings.
|
|
|
|
- ast.literal_eval() can now handle negative numbers. It is also a little more
|
|
liberal in what it accepts without compromising the safety of the evaluation.
|
|
For example, 3j+4 and 3+4+5 are both accepted.
|
|
|
|
- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
|
|
result metaclasses can now be ABCs (see #9533).
|
|
|
|
- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
|
|
|
|
- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
|
|
UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
|
|
32 bits wchar_t (eg. Linux in narrow build).
|
|
|
|
- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
|
|
introduced by issue #9324.
|
|
|
|
- Issue #9979: Create function PyUnicode_AsWideCharString().
|
|
|
|
- Issue #7397: Mention that importlib.import_module() is probably what someone
|
|
really wants to be using in __import__'s docstring.
|
|
|
|
- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
|
|
to use named arguments.
|
|
|
|
- Issue #9930: Remove bogus subtype check that was causing (e.g.)
|
|
float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
|
|
|
|
- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
|
|
|
|
- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
|
|
threads are still running. Instead, reinitialize the GIL on a second call to
|
|
Py_Initialize().
|
|
|
|
- All SyntaxErrors now have a column offset and therefore a caret when the error
|
|
is printed.
|
|
|
|
- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
|
|
module that was imported, but instead gets the module from sys.modules.
|
|
|
|
- Issue #9213: The range type_items now provides index() and count() methods, to
|
|
conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
|
|
|
|
- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
|
|
with a non-empty format string. This is an effort to future-proof user
|
|
code. If a derived class does not currently implement __format__ but later
|
|
adds its own __format__, it would most likely break user code that had
|
|
supplied a format string. This will be changed to a DeprecationWaring in
|
|
Python 3.3 and it will be an error in Python 3.4.
|
|
|
|
- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
|
|
re-created on a subsequent call to Py_Initialize(). The problem (a crash)
|
|
wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
|
|
|
|
- Issue #9210: Configure option --with-wctype-functions was removed. Using the
|
|
functions from the libc caused the methods .upper() and lower() to become
|
|
locale aware and created subtly wrong results.
|
|
|
|
- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
|
|
non-ASCII byte in the format string.
|
|
|
|
- Issue #4617: Previously it was illegal to delete a name from the local
|
|
namespace if it occurs as a free variable in a nested block. This limitation
|
|
of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
|
|
|
|
- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
|
|
``\UXXXXXXXX``, regardless of whether the character is printable or not.
|
|
Also, the "backslashreplace" error handler now joins surrogate pairs into a
|
|
single character on UCS-2 builds.
|
|
|
|
- Issue #9757: memoryview objects get a release() method to release the
|
|
underlying buffer (previously this was only done when deallocating the
|
|
memoryview), and gain support for the context management protocol.
|
|
|
|
- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
|
|
thread-local storage key.
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #2236: distutils' mkpath ignored the mode parameter.
|
|
|
|
- Fix typo in one sdist option (medata-check).
|
|
|
|
- Issue #9199: Fix incorrect use of distutils.cmd.Command.announce.
|
|
|
|
- Issue #1718574: Fix options that were supposed to accept arguments but did
|
|
not in build_clib.
|
|
|
|
- Issue #9437: Fix building C extensions with non-default LDFLAGS.
|
|
|
|
- Issue #4661: email can now parse bytes input and generate either converted
|
|
7bit output or bytes output. Email version bumped to 5.1.0.
|
|
|
|
- Issue #1589: Add ssl.match_hostname(), to help implement server identity
|
|
verification for higher-level protocols.
|
|
|
|
- Issue #9759: GzipFile now raises ValueError when an operation is attempted
|
|
after the file is closed. Patch by Jeffrey Finkelstein.
|
|
|
|
- Issue #9042: Fix interaction of custom translation classes and caching in
|
|
gettext.
|
|
|
|
- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
|
|
returning a (sock, addr) pair which is called when a connection has been
|
|
established with a new remote endpoint. This is supposed to be used as a
|
|
replacement for old handle_accept() and avoids the user to call accept()
|
|
directly.
|
|
|
|
- Issue #9065: tarfile no longer uses "root" as the default for the uname and
|
|
gname field.
|
|
|
|
- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
|
|
an environment that does not have docutils. Patch by Arfrever.
|
|
|
|
- Issue #1050268: parseaddr now correctly quotes double quote and backslash
|
|
characters that appear inside quoted strings in email addresses.
|
|
|
|
- Issue #10004: quoprimime no longer generates a traceback when confronted with
|
|
invalid characters after '=' in a Q-encoded word.
|
|
|
|
- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
|
|
sending a 200 OK for the Expect: 100-continue request header.
|
|
|
|
- Issue #9360: Cleanup and improvements to the nntplib module. The API now
|
|
conforms to the philosophy of bytes and unicode separation in Python 3. A
|
|
test suite has also been added.
|
|
|
|
- Issue #9962: GzipFile now has the peek() method.
|
|
|
|
- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
|
|
retry the select() loop instead of bailing out. This is because select() can
|
|
incorrectly report a socket as ready for reading (for example, if it received
|
|
some data with an invalid checksum).
|
|
|
|
- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
|
|
|
|
- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
|
|
received. Now sendall() properly calls signal handlers if necessary, and
|
|
retries sending if these returned successfully, including on sockets with a
|
|
timeout.
|
|
|
|
- Issue #9947: logging: Fixed locking bug in stopListening.
|
|
|
|
- Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler.
|
|
|
|
- Issue #9936: Fixed executable lines' search in the trace module.
|
|
|
|
- Issue #9790: Rework imports necessary for samefile and sameopenfile
|
|
in ntpath.
|
|
|
|
- Issue #9928: Properly initialize the types exported by the bz2 module.
|
|
|
|
- Issue #1675951: Allow GzipFile to work with unseekable file objects. Patch by
|
|
Florian Festi.
|
|
|
|
- Logging: Added QueueListener class to facilitate logging usage for
|
|
performance-critical threads.
|
|
|
|
- Issue #9916: Add some missing errno symbols.
|
|
|
|
- Issue #9877: Expose sysconfig.get_makefile_filename()
|
|
|
|
- logging: Added hasHandlers() method to Logger and LoggerAdapter.
|
|
|
|
- Issue #9908: Fix os.stat() on bytes paths under Windows 7.
|
|
|
|
- Issue #2643: msync() is not called anymore when deallocating an open mmap
|
|
object, only munmap().
|
|
|
|
- logging: Changed LoggerAdapter implementation internally, to make it easier to
|
|
subclass in a useful way.
|
|
|
|
- logging: hasHandlers method was added to Logger, and isEnabledFor,
|
|
getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
|
|
LoggerAdapter was introduced into the unit tests for logging.
|
|
|
|
- Issue #1686: Fix string.Template when overriding the pattern attribute.
|
|
|
|
- Issue #9854: SocketIO objects now observe the RawIOBase interface in
|
|
non-blocking mode: they return None when an operation would block (instead of
|
|
raising an exception).
|
|
|
|
- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
|
|
another kind.
|
|
|
|
- Issue #9441: logging has better coverage for rotating file handlers.
|
|
|
|
- Issue #9865: collections.OrderedDict now has a __sizeof__ method.
|
|
|
|
- Issue #9854: The default read() implementation in io.RawIOBase now handles
|
|
non-blocking readinto() returning None correctly.
|
|
|
|
- Issue #1552: socket.socketpair() now returns regular socket.socket objects
|
|
supporting the whole socket API (rather than the "raw" _socket.socket
|
|
objects).
|
|
|
|
- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
|
|
to match the corresponding socket methods.
|
|
|
|
- Issue 9840: Added a decorator to reprlib for wrapping __repr__ methods to make
|
|
them handle recursive calls within the same thread.
|
|
|
|
- logging: Enhanced HTTPHandler with secure and credentials initializers.
|
|
|
|
- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
|
|
|
|
- Issue #9837: The read() method of ZipExtFile objects (as returned by
|
|
ZipFile.open()) could return more bytes than requested.
|
|
|
|
- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
|
|
d['x'] = d.
|
|
|
|
- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
|
|
it possible for the user to create self-referencing ordered dictionaries which
|
|
become permanently uncollectable GC garbage. Reinstated the Python 3.1
|
|
approach of using weakref proxies so that reference cycles never get created
|
|
in the first place.
|
|
|
|
- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
|
|
encode the value with filesystem encoding and surrogateescape (instead of
|
|
utf-8 in strict mode) . Patch written by David Watson.
|
|
|
|
- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
|
|
environment variable to set the filesystem encoding at Python startup.
|
|
sys.setfilesystemencoding() creates inconsistencies because it is unable to
|
|
reencode all filenames in all objects.
|
|
|
|
- Issue #9410: Various optimizations to the pickle module, leading to speedups
|
|
up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
|
|
initial patch by Alexandre Vassalotti.
|
|
|
|
- The pprint module now supports printing OrderedDicts in their given order
|
|
(formerly, it would sort the keys).
|
|
|
|
- Logging: Added QueueHandler class to facilitate logging usage with
|
|
multiprocessing.
|
|
|
|
- Issue #9707: Rewritten reference implementation of threading.local which is
|
|
friendlier towards reference cycles. This change is not normally visible
|
|
since an optimized C implementation (_thread._local) is used instead.
|
|
|
|
- Issue #6394: os.getppid() is now supported on Windows. Note that it will
|
|
still return the id of the parent process after it has exited. This process
|
|
id may even have been reused by another unrelated process.
|
|
|
|
- Issue #9792: In case of connection failure, socket.create_connection() would
|
|
swallow the exception and raise a new one, making it impossible to fetch the
|
|
original errno, or to filter timeout errors. Now the original error is
|
|
re-raised.
|
|
|
|
- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
|
|
the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
|
|
back after the system call. Original patch by Brian Brazil.
|
|
|
|
- Updates to the random module:
|
|
|
|
* Document which parts of the module are guaranteed to stay the same across
|
|
versions and which parts are subject to change.
|
|
|
|
* Update the seed() method to use all of the bits in a string instead of just
|
|
the hash value. This makes better use of the seed value and assures the
|
|
seeding is platform independent. Issue #7889.
|
|
|
|
* Improved the random()-->integer algorithm used in choice(), shuffle(),
|
|
sample(), randrange(), and randint(). Formerly, it used int(n*random())
|
|
which has a slight bias whenever n is not a power of two. Issue #9025.
|
|
|
|
* Improved documentation of arguments to randrange(). Issue #9379.
|
|
|
|
- collections.OrderedDict now supports a new method for repositioning keys to
|
|
either end.
|
|
|
|
- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
|
|
cases now also have assertWarns and assertWarnsRegexp methods to check that a
|
|
given warning type was triggered by the code under test.
|
|
|
|
- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
|
|
their contents without duplicating them. The view is both readable and
|
|
writable.
|
|
|
|
- Issue #7566: Implement os.path.sameopenfile for Windows.
|
|
|
|
- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
|
|
unsupported operation is attempted (for example, writing to a file open only
|
|
for reading).
|
|
|
|
- hashlib has two new constant attributes: algorithms_guaranteed and
|
|
algorithms_avaiable that respectively list the names of hash algorithms
|
|
guaranteed to exist in all Python implementations and the names of hash
|
|
algorithms available in the current process.
|
|
|
|
- A new package ``concurrent.futures`` as defined by PEP 3148.
|
|
|
|
C-API
|
|
-----
|
|
|
|
- Add PyErr_SyntaxLocationEx, which supports passing a column offset.
|
|
|
|
- Issue #9834: Don't segfault in PySequence_GetSlice, PySequence_SetSlice, or
|
|
PySequence_DelSlice when the object doesn't have any mapping operations
|
|
defined.
|
|
|
|
Tools/Demos
|
|
-----------
|
|
|
|
- Issue #9188: The gdb extension now handles correctly narrow (UCS2) as well as
|
|
wide (UCS4) unicode builds for both the host interpreter (embedded inside gdb)
|
|
and the interpreter under test.
|
|
|
|
Tests
|
|
-----
|
|
|
|
- Issue #9308: Added tests for importing encoded modules that do not

What's New in Python 3.2 Alpha 2?
|
|
=================================
|
|
|
|
*Release date: 05-Sep-2010*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
|
|
the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
|
|
bytecode is a bit simplified. Patch by Demur Rumed.
|
|
|
|
- Issue #9766: Rename poorly named variables exposed by _warnings to prevent
|
|
confusion with the proper variables names from 'warnings' itself.
|
|
|
|
- Issue #9212: dict_keys and dict_items now provide the isdisjoint() method, to
|
|
conform to the Set ABC. Patch by Daniel Urban.
|
|
|
|
- Issue #9737: Fix a crash when trying to delete a slice or an item from a
|
|
memoryview object.
|
|
|
|
- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
|
|
now removed, since their effect was inexistent in 3.x (the default encoding is
|
|
hardcoded to utf-8 and cannot be changed).
|
|
|
|
- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
|
|
properly. Patch by Stefan Behnel.
|
|
|
|
- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
|
|
platforms. Previously, it inlined only when using Microsoft Visual C.
|
|
|
|
- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
|
|
|
|
- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
|
|
|
|
- Issue #9684: Added a definition for SIZEOF_WCHAR_T to PC/pyconfig.h, to match
|
|
the pyconfig.h generated by configure on other systems.
|
|
|
|
- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that
|
|
occur during attribute lookup are now propagated to the caller.
|
|
|
|
- Issue #8622: Add PYTHONFSENCODING environment variable to override the
|
|
filesystem encoding.
|
|
|
|
- Issue #5127: The C functions that access the Unicode Database now accept and
|
|
return characters from the full Unicode range, even on narrow unicode builds
|
|
(Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
|
|
in Python is that unicodedata.numeric() now returns the correct value for
|
|
large code points, and repr() may consider more characters as printable.
|
|
|
|
- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
|
|
as a unicode object, instead of a byte string. Function needed to support
|
|
unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
|
|
function.
|
|
|
|
- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().
|
|
|
|
- Issue #9612: The set object is now 64-bit clean under Windows.
|
|
|
|
- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
|
|
the module file to be executed with the -m command line option.
|
|
|
|
- Issue #9599: Create PySys_FormatStdout() and PySys_FormatStderr() functions to
|
|
write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
|
|
sys.stderr.
|
|
|
|
- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
|
|
decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
|
|
objects are output as-is.
|
|
|
|
- Issue #9203: Computed gotos are now enabled by default on supported compilers
|
|
(which are detected by the configure script). They can still be disable
|
|
selectively by specifying --without-computed-gotos.
|
|
|
|
- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
|
|
use PyUnicode_FromFormatV() to format the warning message.
|
|
|
|
- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
|
|
array.
|
|
|
|
- Issue #5319: Print an error if flushing stdout fails at interpreter shutdown.
|
|
|
|
- Issue #9337: The str() of a float or complex number is now identical to its
|
|
repr().
|
|
|
|
- Issue #9416: Fix some issues with complex formatting where the output with no
|
|
type specifier failed to match the str output:
|
|
|
|
- format(complex(-0.0, 2.0), '-') omitted the real part from the output,
|
|
- format(complex(0.0, 2.0), '-') included a sign and parentheses.
|
|
|
|
Extension Modules
|

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

- Issue #8013: time.asctime and time.ctime no longer call system
|
|
asctime and ctime functions. The year range for time.asctime is now

|
1900 through maxint. The range for time.ctime is the same as for
|
|
time.localtime. The string produced by these functions is longer
|
|
than 24 characters when year is greater than 9999.
|
|
|
|
- Issue #6608: time.asctime is now checking struct tm fields its input

What's New in Python 3.2 Alpha 1?
|
|
=================================
|
|
|
|
*Release date: 01-Aug-2010*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #8991: convertbuffer() rejects discontigious buffers.
|
|
|
|
- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
|
|
compiler.
|
|
|
|
- Issue #8413: structsequence now subclasses tuple.
|
|
|
|
- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
|
|
start byte and the continuation byte(s) are now considered invalid, instead of
|
|
the number of bytes specified by the start byte. E.g.:
|
|
'\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
|
|
with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
|
|
even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
|
|
returned a single u'\ufffd'.
|
|
|
|
- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
|
|
rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
|
|
|
|
- Be more specific in error messages about positional arguments.
|
|
|
|
- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
|
|
objects, as described in the documentation.
|
|
|
|
- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
|
|
Fix the encoding of the modules filename. Patch written by Amaury Forgeot
|
|
d'Arc.
|
|
|
|
- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
|
|
dealing with unary minus applied to a constant. The removed code was mutating
|
|
the ST, causing a second compilation to fail.
|
|
|
|
- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
|
|
mode raises unicode errors. The encoder only supports "strict" and "replace"
|
|
error handlers, the decoder only supports "strict" and "ignore" error
|
|
handlers. Patch written by Mark Hammond.
|
|
|
|
- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
|
|
"w*" format instead. Add tests for "w*" format.
|
|
|
|
- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
|
|
formats if the string contains a null byte/character. Write unit tests for
|
|
string formats.
|
|
|
|
- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
|
|
suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
|
|
location of the raised exception.
|
|
|
|
- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
|
|
filenames and enable os.fsencode().
|
|
|
|
- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
|
|
|
|
- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
|
|
interpreter with characters outside the Basic Multilingual Plane (higher than
|
|
0x10000).
|
|
|
|
- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
|
|
TypeError instead of giving a DeprecationWarning when a float is parsed using
|
|
the 'L' code (for long long). (All other integer codes already raise
|
|
TypeError in this case.)
|
|
|
|
- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
|
|
enable shortcuts for upper case encoding name. Add also a shortcut for
|
|
"iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
|
|
|
|
- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
|
|
doesn't support "char buffer" anymore in Python 3.
|
|
|
|
- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
|
|
instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
|
|
like bytearray.
|
|
|
|
- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
|
|
used anymore and it was never documented.
|
|
|
|
- In str.format(), raise a ValueError when indexes to arguments are too large.
|
|
|
|
- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
|
|
integers n (including n = -909).
|
|
|
|
- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
|
|
of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
|
|
easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
|
|
equal value.
|
|
|
|
- Issue #8748: Fix two issues with comparisons between complex and integer
|
|
objects. (1) The comparison could incorrectly return True in some cases
|
|
(2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
|
|
(2) The comparison raised an OverflowError for large integers, leading to
|
|
unpredictable exceptions when combining integers and complex objects in sets
|
|
or dicts.
|
|
|
|
- Issue #8766: Initialize _warnings module before importing the first module.
|
|
Fix a crash if an empty directory called "encodings" exists in sys.path.
|
|
|
|
- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
|
|
encoding and surrogateescape error handler instead of the locale encoding to
|
|
be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
|
|
|
|
- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
|
|
of strict) error handler to escape surrogates.
|
|
|
|
- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
|
|
object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
|
|
handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
|
|
back to UTF-8.
|
|
|
|
- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
|
|
error handler, not only the default error handler (strict).
|
|
|
|
- Issue #8610: Load file system codec at startup, and display a fatal error on
|
|
failure. Set the file system encoding to utf-8 (instead of None) if getting
|
|
the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
|
|
|
|
- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
|
|
PyUnicode_FromString() to support surrogates in the filename and use the right
|
|
encoding.
|
|
|
|
- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
|
|
|
|
- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
|
|
|
|
- Issue #8419: Prevent the dict constructor from accepting non-string keyword
|
|
arguments.
|
|
|
|
- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
|
|
indirectly Python signal handlers anymore because mywrite() ignores exceptions
|
|
(KeyboardInterrupt).
|
|
|
|
- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
|
|
unicode string (eg. backslashreplace).
|
|
|
|
- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
|
|
anymore, you have to convert your bytearray filenames to bytes.
|
|
|
|
- Issue #7332: Remove the 16KB stack-based buffer in
|
|
PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
|
|
compared to the dynamic memory allocation fallback. Patch by Charles-François
|
|
Natali.
|
|
|
|
- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
|
|
passed to bytes or bytearray.
|
|
|
|
- Issue #7301: Add environment variable $PYTHONWARNINGS.
|
|
|
|
- Issue #8329: Don't return the same lists from select.select when no fds are
|
|
changed.
|
|
|
|
- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error' on
|
|
64-bit machines. The shift count for either left or right shift is permitted
|
|
to be up to sys.maxsize.
|
|
|
|
- Ensure that tokenization of identifiers is not affected by locale.
|
|
|
|
- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
|
|
|
|
- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
|
|
|
|
- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
|
|
is set.
|
|
|
|
- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
|
|
is unknown.
|
|
|
|
- Issue #1583863: A str subclass can now override the __str__ method.
|
|
|
|
- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
|
|
PyMemberDefs could produce an internal error; raise TypeError instead.
|
|
|
|
- Issue #7845: Rich comparison methods on the complex type now return
|
|
NotImplemented rather than raising a TypeError when comparing with an
|
|
incompatible type; this allows user-defined classes to implement their own
|
|
comparisons with complex.
|
|
|
|
- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
|
|
(SIGINT). If an error occurs while importing the site module, the error is
|
|
printed and Python exits. Initialize the GIL before importing the site module.
|
|
|
|
- Issue #7173: Generator finalization could invalidate sys.exc_info().
|
|
|
|
- Issue #7544: Preallocate thread memory before creating the thread to avoid a
|
|
fatal error in low memory condition.
|
|
|
|
- Issue #7820: The parser tokenizer restores all bytes in the right if the BOM
|
|
check fails.
|
|
|
|
- Handle errors from looking up __prepare__ correctly.
|
|
|
|
- Issue #5939: Add additional runtime checking to ensure a valid capsule in
|
|
Modules/_ctypes/callproc.c.
|
|
|
|
- Issue #7309: Fix unchecked attribute access when converting
|
|
UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to strings.
|
|
|
|
- Issue #6902: Fix problem with built-in types format incorrectly with 0
|
|
padding.
|
|
|
|
- Issue #7988: Fix default alignment to be right aligned for complex.__format__.
|
|
Now it matches other numeric types.
|
|
|
|
- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
|
|
PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string and
|
|
PyOS_string_to_double instead. See issue #5835 for the original deprecations.
|
|
|
|
- Issue #7385: Fix a crash in `MemoryView_FromObject` when `PyObject_GetBuffer`
|
|
fails. Patch by Florent Xicluna.
|
|
|
|
- Issue #7788: Fix an interpreter crash produced by deleting a list slice with
|
|
very large step value.
|
|
|
|
- Issue #7766: Change sys.getwindowsversion() return value to a named tuple and
|
|
add the additional members returned in an OSVERSIONINFOEX structure. The new
|
|
members are service_pack_major, service_pack_minor, suite_mask, and
|
|
product_type.
|
|
|
|
- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`) could
|
|
crash in many places because of the PyByteArray_AS_STRING() macro returning
|
|
NULL. The macro now returns a statically allocated empty string instead.
|
|
|
|
- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
|
|
where the right hand operand is a set of constants, by turning the set into a
|
|
frozenset and pre-building it as a constant. The comparison operation is made
|
|
against the constant instead of building a new set each time it is executed (a
|
|
similar optimization already existed which turned a list of constants into a
|
|
pre-built tuple). Patch and additional tests by Dave Malcolm.
|
|
|
|
- Issue #7622: Improve the split(), rsplit(), splitlines() and replace() methods
|
|
of bytes, bytearray and unicode objects by using a common implementation based
|
|
on stringlib's fast search. Patch by Florent Xicluna.
|
|
|
|
- Issue #7632: Fix various str -> float conversion bugs present in 2.7 alpha 2,
|
|
including: (1) a serious 'wrong output' bug that could occur for long (> 40
|
|
digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
|
|
parsing certain long numeric strings corresponding to subnormal values, (3) a
|
|
memory leak for some values large enough to cause overflow, and (4) a number
|
|
of flaws that could lead to incorrectly rounded results.
|
|
|
|
- The __complex__ method is now looked up on the class of instances to make it
|
|
consistent with other special methods.
|
|
|
|
- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
|
|
`rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
|
|
|
|
- Issue #7604: Deleting an unset slotted attribute did not raise an
|
|
AttributeError.
|
|
|
|
- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
|
|
in ** operator. The behaviour now conforms to that described in C99 Annex F.
|
|
|
|
- Issue #1811: improve accuracy and cross-platform consistency for true division
|
|
of integers: the result of a/b is now correctly rounded for ints a and b (at
|
|
least on IEEE 754 platforms), and in particular does not depend on the
|
|
internal representation of an int.
|
|
|
|
- Issue #6834: replace the implementation for the 'python' and 'pythonw'
|
|
executables on OSX.
|
|
|
|
These executables now work properly with the arch(1) command: ``arch -ppc
|
|
python`` will start a universal binary version of python in PPC mode (unlike
|
|
previous releases).
|
|
|
|
- Issue #7466: Segmentation fault when the garbage collector is called in the
|
|
middle of populating a tuple. Patch by Florent Xicluna.
|
|
|
|
- Issue #7419: setlocale() could crash the interpreter on Windows when called
|
|
with invalid values.
|
|
|
|
- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
|
|
mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
|
|
|
|
- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
|
|
10.6.
|
|
|
|
- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
|
|
|
|
- Issue #6970: Remove redundant calls when comparing objects that don't
|
|
implement the relevant rich comparison methods.
|
|
|
|
- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
|
|
range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
|
|
long but the length of the range did not. Also fix several cases where
|
|
reversed(range(a, b, c)) gave wrong results, and fix a refleak for
|
|
reversed(range(a, b, c)) with large arguments.
|
|
|
|
- Issue #7244: itertools.izip_longest() no longer ignores exceptions raised
|
|
during the formation of an output tuple.
|
|
|
|
- Issue #3297: On wide unicode builds, do not split unicode characters into
|
|
surrogates.
|
|
|
|
- Remove length limitation when constructing a complex number from a string.
|
|
|
|
- Issue #1087418: Boost performance of bitwise operations for longs.
|
|
|
|
- Support for AtheOS has been completely removed from the code base. It was
|
|
disabled since Python 3.0.
|
|
|
|
- Support for several legacy threading libraries has been disabled. These
|
|
libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
|
|
will be entirely removed in 3.3.
|
|
|
|
- Support for OSF* has been disabled. If nobody stands up, support will be
|
|
removed in 3.3. See <http://bugs.python.org/issue8606>.
|
|
|
|
- Peephole constant folding had missed UNARY_POSITIVE.
|
|
|
|
- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
|
|
fixes the problem of some exceptions being thrown at shutdown when the
|
|
interpreter is killed. Patch by Adam Olsen.
|
|
|
|
- Issue #7147: Remove support for compiling Python without complex number
|
|
support.
|
|
|
|
- Issue #7120: logging: Removed import of multiprocessing which is causing crash
|
|
in GAE.
|
|
|
|
- Issue #1754094: Improve the stack depth calculation in the compiler. There
|
|
should be no other effect than a small decrease in memory use. Patch by
|
|
Christopher Tur Lesniewski-Laas.
|
|
|
|
- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when using
|
|
byte values greater than 127. Patch by Derk Drukker.
|
|
|
|
- Issue #1571184: The Unicode database contains properties for more characters.
|
|
The tables for code points representing numeric values, white spaces or line
|
|
breaks are now generated from the official Unicode Character Database files,
|
|
and include information from the Unihan.txt file.
|
|
|
|
- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of
|
|
producing internally inconsistent Python longs.
|
|
|
|
- Issue #6990: Fix threading.local subclasses leaving old state around after a
|
|
reference cycle GC which could be recycled by new locals.
|
|
|
|
- Issue #5460: Fix an ambiguity in the grammar.
|
|

|
|
|
|
- Issue #6846: Fix bug where bytearray.pop() returns negative integers.
|
|

writing from multiple threads at the same time.
|
|
|
|
- Issue #6707: dir() on an uninitialized module caused a crash.
|
|
|
|
- Issue #6540: Fixed crash for bytearray.translate() with invalid parameters.

- Issue #6573: set.union() stopped processing inputs if an instance of self
|
|
occurred in the argument chain.
|
|
|
|
- Issue #6070: On posix platforms import no longer copies the execute bit from
|
|
the .py file to the .pyc file if it is set.
|
|
|
|
- Issue #1616979: Added the cp720 (Arabic DOS) encoding.
|
|
|
|
- Issue #6428: Since Python 3.0, the __bool__ method must return a bool object,
|
|
and not an int. Fix the corresponding error message, and the documentation.
|
|
|
|
- The deprecated PyCObject has been removed.
|
|
|
|
- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
|
|
build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
|
|
of stdint.h on that platform.
|
|
|
|
- Issue #6373: Fixed a SystemError when encoding with the latin-1 codec and the
|
|
'surrogateescape' error handler, a string which contains unpaired surrogates.
|
|
|
|

- Issue #6687: PyBytes_FromObject() no longer accepts an integer as its argument
|
|
to construct a null-initialized bytes object.
|
|
|
|
- Issue #1023290: Add from_bytes() and to_bytes() methods to integers. These
|
|
methods allow the conversion of integers to bytes, and vice-versa.
|
|
|
|
- Issue #7382: Fix bug in bytes.__getnewargs__ that prevented bytes instances
|
|
from being copied with copy.copy(), and bytes subclasses from being pickled
|
|
properly.
|
|
|
|
- Code objects now support weak references.
|
|
|
|
- Issue #7072: isspace(0xa0) is true on Mac OS X.
|
|
|
|
- Issue #8084: PEP 370 now conforms to system conventions for framework builds
|
|
on MacOS X. That is, "python setup.py install --user" will install into
|
|
"~/Library/Python/2.7" instead of "~/.local".
|
|
|
|
C-API
|
|
-----
|
|
|
|
- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
|
|
variable argument list. `Py_VA_COPY` is equivalent to C99
|
|
`va_copy`, but available on all python platforms.
|
|
|
|
- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
|
|
instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
|
|
"step = -step" when reversing a slice.
|
|
|
|
- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the
|
|
interpreter to set sys.argv without also modifying sys.path. This helps fix
|
|
`CVE-2008-5983
|
|
<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
|
|
|
|
- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
|
|
strings in an efficient manner.
|
|
|
|
- Issue #8276: PyEval_CallObject() is now only available in macro form. The
|
|
function declaration, which was kept for backwards compatibility reasons, is
|
|
now removed (the macro was introduced in 1997!).
|
|
|
|
- Issue #7767: New function PyLong_AsLongLongAndOverflow added, analogous to
|
|
PyLong_AsLongAndOverflow.
|
|
|
|
- Make PyUnicode_CompareWithASCIIString return not equal if the Python string
|
|
has '\0' at the end.
|
|
|
|
- Issue #5080: The argument parsing functions PyArg_ParseTuple,
|
|
PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
|
|
PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
|
|
'L' format code. This will become a TypeError in a future version of Python,
|
|
to match the behaviour of the other integer format codes.
|
|
|
|
- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.
|
|
|
|
- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments) in
|
|
PyArg_ParseTupleAndKeywords.
|
|
|
|
- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V) and
|
|
PyErr_Format, on machines with HAVE_LONG_LONG defined.
|
|
|
|
- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
|
|
PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
|
|

|
- In pdb, when Ctrl-C is entered while defining commands for a breakpoint, the
|
|
old commands are restored.
|
|
|
|
- For traceback debugging, the pdb listing now also shows the locations where
|
|
the exception was originally (re)raised, if it differs from the last line
|
|
executed (e.g. in case of finally clauses).
|
|
|
|
- The pdb command "source" has been added. It displays the source code for a
|
|
given object, if possible.
|
|
|
|
- The pdb command "longlist" has been added. It displays the whole source code
|
|
for the current function.

|
|
output into methods.

|
|
reassigned.
|
|
|
|

|
|
files. Also, add a command-line option "-c" that runs a command as if given
|
|
in .pdbrc.
|
|
|
|
- Issue #4179: In pdb, allow "list ." as a command to return to the currently
|
|

|
- The default size of the re module's compiled regular expression cache has been
|
|
increased from 100 to 500 and the cache replacement policy has changed from
|
|
simply clearing the entire cache on overflow to forgetting the least recently
|
|
used cached compiled regular expressions. This is a performance win for
|
|
applications that use a lot of regular expressions and limits the impact of
|
|
the performance hit anytime the cache is exceeded.

- Issue #7989: Added pure python implementation of the `datetime` module. The C
|
|
module is renamed to `_datetime` and if available, overrides all classes
|
|
defined in datetime with fast C impementation. Python implementation is based
|
|
on the original python prototype for the datetime module by Tim Peters with
|
|
minor modifications by the PyPy project. The test suite now tests `datetime`
|
|
module with and without `_datetime` acceleration using the same test cases.

|
iteration over 'locals()' in Context.__init__.
|
|

|
- Fix extreme speed issue in Decimal.pow when the base is an exact power of 10
|
|

|
|
operation raises multiple signals and more than one of those signals is
|

trapped, the specification determines the order in which the signals should be
|
|
handled. In many cases this order wasn't being followed, leading to the wrong

|
Python exception being raised.

- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
|
|
using backslashreplace error handler.
|
|
|
|
- Issue #8412: os.system() now accepts bytes, bytearray and str with surrogates.
|
|
|
|
- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
|
|
Locke and Hans Ulrich Niedermann.
|
|
|
|
- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
|
|
|
|
- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
|
|
module now takes an optional timeout argument in seconds. Timeout support
|
|
relies on the system threading library, so as to avoid a semi-busy wait loop.
|
|
|
|
- Issue #8383: pickle and pickletools use surrogatepass error handler when
|
|
encoding unicode as utf8 to support lone surrogates and stay compatible with
|
|
Python 2.x and 3.x.
|
|
|
|
- Issue #7585: difflib context and unified diffs now place a tab between
|
|
filename and date, conforming to the 'standards' they were originally designed
|
|
to follow. This improves compatibility with patch tools.
|
|
|
|
- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
|
|
character sets will now consistently use a Content-Transfer-Encoding of 7bit
|
|
rather than sometimes being marked as 8bit.
|
|
|
|
- Issue #8375: test_distutils now checks if the temporary directory are still
|
|
present before it cleans them.
|
|
|
|
- Issue #8374: Update the internal alias table in the :mod:`locale` module to
|
|
cover recent locale changes and additions.
|
|
|
|
- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
|
|
using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
|
|
`ssl.OPENSSL_VERSION_NUMBER`.
|
|
|
|
- Add functools.total_ordering() and functools.cmp_to_key().
|
|
|
|
- Issue #8257: The Decimal construct now accepts a float instance directly,
|
|
converting that float to a Decimal of equal value:
|
|
|
|
>>> Decimal(1.1)
|
|
Decimal('1.100000000000000088817841970012523233890533447265625')
|
|
|
|
- Issue #8294: The Fraction constructor now accepts Decimal and float instances
|
|
directly.
|
|
|
|
- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
|
|
InvalidOperation instead of returning False. (Comparisons involving a quiet
|
|
NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
|
|
signaling NaNs remain unhashable.
|
|
|
|
- Issue #2531: Comparison operations between floats and Decimal instances now
|
|
return a result based on the numeric values of the operands; previously they
|
|
returned an arbitrary result based on the relative ordering of id(float) and
|
|
id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
|
|
comparisons.
|
|
|
|
- Added a subtract() method to collections.Counter().
|
|
|
|
- Issue #8233: When run as a script, py_compile.py optionally takes a single
|
|
argument `-` which tells it to read files to compile from stdin. Each line is
|
|
read on demand and the named file is compiled immediately. (Original patch by
|
|
Piotr Ożarowski).
|
|
|
|
- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
|
|
form feed (0x0C) are now considered linebreaks, as specified in Unicode
|
|
Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
|
|
|
|
- Comparisons using one of <, <=, >, >= between a complex instance and a
|
|
Fractions instance now raise TypeError instead of returning True/False. This
|
|
makes Fraction <=> complex comparisons consistent with int <=> complex, float
|
|
<=> complex, and complex <=> complex comparisons.
|
|
|
|
- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some
|
|
methods (such as oss_mixer_device.fileno()) were not available. Initial patch
|
|
by Bertrand Janin.
|
|
|
|
- Issue #8205: Remove the "Modules" directory from sys.path when Python is
|
|
running from the build directory (POSIX only).
|
|
|
|
- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
|
|
didn't support chflags() (for example ZFS under FreeBSD). The error is now
|
|
silenced.
|
|
|
|
- Issue #7860: platform.uname now reports the correct 'machine' type when Python
|
|
is running in WOW64 mode on 64 bit Windows.
|
|
|
|
- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
|
|
Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
|
|
reads and writes are always retried by OpenSSL itself.
|
|
|
|
- Issue #4282: Fix the main function of the profile module for a non-ASCII
|
|
script, open the file in binary mode and not in text mode with the default
|
|
(utf8) encoding.
|
|
|
|
- Issue #8179: Fix macpath.realpath() on a non-existing path.
|
|
|
|
- Issue #8024: Update the Unicode database to 5.2.
|
|
|
|
- Issue #8168: py_compile now handles files with utf-8 BOMS.
|
|
|
|
- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
|
|
detected.
|
|
|
|

|
|
with Tcl/Tk-8.5.
|

|
- Issue #8140: extend compileall to compile single files. Add -i option.
|
|
|
|
- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of the
|
|
locale.
|
|
|
|
- The internals of the subprocess module on POSIX systems have been replaced by
|
|
an extension module (_posixsubprocess) so that the fork()+exec() can be done
|
|
safely without the possibility of deadlock in multithreaded applications.
|
|
|
|
- subprocess.Popen now has restore_signals and start_new_session features. The
|
|
default of restore_signals=True is a new behavior compared to earlier Python
|
|
versions. This means that signals such as SIGPIPE are not ignored by default
|
|
in subprocesses launched by Python (Issue #1652).
|
|
|
|
- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
|
|
cElementTree module is updated too.
|
|

|
|
an non existent program name and Python is unable to retrieve the real program
|
|
name.

|
|
replacement were all bytes. Patch by Antoine Pitrou.

|
|
ignored only to the first file. Noted by Bogdan Opanchuk.
|
|
|
|
- Issue #7597: curses.use_env() can now be called before initscr(). Noted by

|
|
messages parsed by email.Parser.HeaderParser.

|
|
- Issue #7361: Importlib was not properly checking the number of bytes in
|
|
bytecode file when it was less then 8 bytes.
|
|
|
|
- Issue #7633: In the decimal module, Context class methods (with the exception
|
|
of canonical and is_canonical) now accept instances of int and long wherever a
|
|
Decimal instance is accepted, and implicitly convert that argument to Decimal.
|
|
Previously only some arguments were converted.
|
|
|
|
- Issue #7835: shelve should no longer produce mysterious warnings during
|
|
interpreter shutdown.
|
|
|
|
- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in XML
|
|
processing instructions and comments. These raw characters are allowed by the
|
|
XML specification, and are necessary when outputting e.g. PHP code in a
|
|
processing instruction. Patch by Neil Muller.
|
|
|
|
- Issue #6233: ElementTree failed converting unicode characters to XML entities
|
|
when they could't be represented in the requested output encoding. Patch by
|
|
Jerry Chen.
|
|
|
|
- Issue #6003: add an argument to ``zipfile.Zipfile.writestr`` to specify the
|
|
compression type.
|
|
|
|
- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
|
|
specified, rather than fall through to AF_PACKET (in the `socket` module).
|
|
Also, raise ValueError rather than TypeError when an unknown TIPC address type
|
|
is specified. Patch by Brian Curtin.
|
|
|
|
- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
|
|
position when calling `truncate()`. It would previously change the file
|
|
position to the given argument, which goes against the tradition of
|
|
ftruncate() and other truncation APIs. Patch by Pascal Chambon.
|
|
|
|
- Issue #7610: Reworked implementation of the internal
|
|
:class:`zipfile.ZipExtFile` class used to represent files stored inside an
|
|
archive. The new implementation is significantly faster and can be wrapped in
|
|
a :class:`io.BufferedReader` object for more speedups. It also solves an
|
|
issue where interleaved calls to `read()` and `readline()` give wrong results.
|
|
Patch by Nir Aides.
|
|
|
|
- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
|
|
allowing for a maximum number of tasks within the pool to be completed by the

|
Extension extra options may change the output without changing the .c
|
|
file). Initial patch by Collin Winter.
|
|
|
|
- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc

|
|
Stinner.
|
|
|
|
- Issue #1628205: Socket file objects returned by socket.socket.makefile() now
|
|
properly handles EINTR within the read, readline, write & flush methods. The
|
|
socket.sendall() method now properly handles interrupted system calls.
|
|
|
|
- Issue #7471: Improve the performance of GzipFile's buffering mechanism, and
|
|
make it implement the `io.BufferedIOBase` ABC to allow for further speedups by
|
|
wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
|

|
parameter to allow specifying where your connections come from.
|
|
|
|

|
|
- Issue #5511: now zipfile.ZipFile can be used as a context manager. Initial
|
|
patch by Brian Curtin.
|
|
|
|
- Issue #7556: Make sure Distutils' msvc9compile reads and writes the MSVC XML
|
|
Manifest file in text mode so string patterns can be used in regular
|
|
expressions.
|
|
|
|
- Issue #7552: Removed line feed in the base64 Authorization header in the
|
|
Distutils upload command to avoid an error when PyPI reads it. This occurs on

|
long passwords. Initial patch by JP St. Pierre.
|

- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by
|
|
Tatsuhiro Tsujikawa.

|
|
Patch by Victor Stinner and Florent Xicluna.
|
|
|
|
- Issue #7349: Make methods of file objects in the io module accept None as an

|
|
access to the initgroups(3) C library call on Unix systems which implement it.
|
|
Patch by Jean-Paul Calderone.
|
|
|
|
- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
|
|
ownership when the group is not forced, because the group may be different
|
|
from the user's group and inherit from its container when the test is run.
|
|
|
|
- Issue #4486: When an exception has an explicit cause, do not print its

|
|
of an error.

|
|
Windows box. Help provided by David Bolen.
|
|
|

|
- Issue #4969: The mimetypes module now reads the MIME database from the
|
|
registry under Windows. Patch by Gabriel Genellina.
|
|
|
|
- Issue #6816: runpy now provides a run_path function that allows Python code to
|
|
execute file paths that refer to source or compiled Python files as well as
|
|
zipfiles, directories and other valid sys.path entries that contain a
|
|
__main__.py file. This allows applications that run other Python scripts to
|
|
support the same flexibility as the CPython command line itself.
|
|
|
|
- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
|
|
connection with another process, rather than looping endlessly. The default
|
|
timeout is 20 seconds, which should be amply sufficient for local connections.
|
|
|
|
- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and
|
|
unpickled. This fixes crashes under Windows when trying to run
|
|
test_multiprocessing in verbose mode.
|
|
|
|
- Issue #7893: ``unittest.TextTestResult`` is made public and a ``resultclass``
|
|
argument added to the TextTestRunner constructor allowing a different result
|
|
class to be used without having to subclass.
|
|
|
|
- Issue #7588: ``unittest.TextTestResult.getDescription`` now includes the test
|
|
name in failure reports even if the test has a docstring.
|
|
|
|
- Issue #3001: Add a C implementation of recursive locks which is used by
|
|
default when instantiating a `threading.RLock` object. This makes recursive
|
|
locks as fast as regular non-recursive locks (previously, they were slower by
|
|
10x to 15x).
|
|
|
|
- Issue #7282: Fix a memory leak when an RLock was used in a thread other than
|
|
those started through `threading.Thread` (for example, using
|
|
`_thread.start_new_thread()`).
|
|
|

|
|
objects on 64-bit systems. Patch by Michael Broghton.

|
|
modification is done through it. This fixes inconsistencies and test failures
|
|
on systems with slightly bogus mtime behaviour.
|
|
|
|
- Issue #7246 & Issue #7208: getpass now properly flushes input before reading
|
|
from stdin so that existing input does not confuse it and lead to incorrect
|
|
entry or an IOError. It also properly flushes it afterwards to avoid the
|
|
terminal echoing the input afterwards on OSes such as Solaris.
|
|
|
|
- Issue #7233: Fix a number of two-argument Decimal methods to make sure that
|
|
they accept an int or long as the second argument. Also fix buggy handling of
|
|
large arguments (those with coefficient longer than the current precision) in
|
|
shift and rotate.
|
|
|
|
- Issue #4750: Store the basename of the original filename in the gzip FNAME
|
|

|
|
larger than emax.
|
|

|
|
platforms, and assorted locale fixes by Derk Drukker.

|
|
|
|

|
|
should be raised, not AttributeError.
|
|
|
|
- When the globals past to importlib.__import__() has __package__ set to None,
|
|
fall back to computing what __package__ should be instead of giving up.
|

- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
|
|
loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
|
|
PyPycLoader inherit from this class and provide implementations in relation to
|
|
other methods required by the ABCs.
|
|
|
|
- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

the documentation said it did even though the code in PyLoader relied on the
|
|
abstract method required by ResourceLoader.
|
|

|
Extension Modules
|
|
-----------------
|
|
|
|
- Issue #9959: Tweak formula used for computing math.log of an integer,
|
|
making it marginally more accurate for exact powers of 2.
|
|
|
|
- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
|
|
|
|
- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
|
|
compared to other unix systems. In particular, os.getgroups() does not reflect
|
|
any changes made using os.setgroups() but basicly always returns the same
|
|
information as the id command. os.getgroups() can now return more than 16
|
|
groups on MacOSX.
|
|
|
|
- Issue #6095: Make directory argument to os.listdir optional.
|
|
|
|
- Issue #9277: Fix bug in struct.pack for bools in standard mode (e.g.,
|
|
struct.pack('>?')): if conversion to bool raised an exception then that
|
|
exception wasn't properly propagated on machines where char is unsigned.
|
|
|
|
- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x python when
|
|
they contain instances of old-style classes.
|
|
|
|
- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to accompany
|
|
existing isinf and isnan functions.
|
|
|
|
- Issue #1578269: Implement os.symlink for Windows 6.0+. Patch by Jason
|
|
R. Coombs.
|
|
|
|
- In struct.pack, correctly propogate exceptions from computing the truth of an
|
|
object in the '?' format.
|
|
|
|
- Issue #9000: datetime.timezone objects now have eval-friendly repr.
|
|
|
|
- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
|
|
special methods.
|
|
|
|
- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
|
|
Prior to this change, timezone adjustment in utctimetuple() could produce
|
|
tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
|
|
cases.
|
|
|
|
- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
|
|
directive. When the ``%z`` directive is present in the format string, an
|
|
aware ``datetime`` object is returned with ``tzinfo`` bound to a
|
|
``datetime.timezone`` instance constructed from the parsed offset. If both
|
|
``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
|
|
name, but ``%Z`` data without ``%z`` is discarded.
|
|
|
|
- Issue #5094: The ``datetime`` module now has a simple concrete class
|
|
implementing ``datetime.tzinfo`` interface. Instances of the new class,
|
|
``datetime.timezone``, return fixed name and UTC offset from their
|
|
``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
|
|
returns ``None``. A class attribute, ``utc`` contains an instance
|
|
representing the UTC timezone. Original patch by Rafe Kaplan.
|
|
|
|
- Issue #8973: Add __all__ to struct module; this ensures that help(struct)
|
|
includes documentation for the struct.Struct class.
|
|
|
|
- Issue #3129: Trailing digits in struct format string are no longer ignored.
|
|
For example, "1" or "ilib123" are now invalid formats and cause
|
|
``struct.error`` to be raised. Patch by Caleb Deveraux.
|
|
|
|
- Issue #7384: If the system readline library is linked against ncurses, the
|
|
curses module must be linked against ncurses as well. Otherwise it is not safe
|
|
to load both the readline and curses modules in an application.
|
|
|
|
- Issue #2810: Fix cases where the Windows registry API returns ERROR_MORE_DATA,
|
|
requiring a re-try in order to get the complete result.
|
|
|
|
- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
|
|
with an improved 'binary-split' algorithm that uses fewer multiplications and
|
|
allows many of the multiplications to be performed using plain C integer
|
|
arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
|
|
arguments.
|
|
|
|
- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
|
|
overflow checks in the audioop module.
|
|
|
|
- Issue #8644: The accuracy of td.total_seconds() has been improved (by
|
|
calculating with integer arithmetic instead of float arithmetic internally):
|
|
the result is now always correctly rounded, and is equivalent to ``td /
|
|
timedelta(seconds=1)``.
|
|
|
|
- Issue #2706: Allow division of a timedelta by another timedelta: timedelta /
|
|
timedelta, timedelta % timedelta, timedelta // timedelta and divmod(timedelta,
|
|
timedelta) are all supported.
|
|
|
|
- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
|
|
|
|
- Issue #8300: When passing a non-integer argument to struct.pack with any
|
|
integer format code, struct.pack first attempts to convert the non-integer
|
|
using its __index__ method. If that method is non-existent or raises
|
|
TypeError it goes on to try the __int__ method, as described below.
|
|
|
|
- Issue #8142: Update libffi to the 3.0.9 release.
|
|
|
|
- Issue #6949: Allow the _dbm extension to be built with db 4.8.x.
|
|
|
|
- Issue #6544: Fix a reference leak in the kqueue implementation's error
|
|
handling.
|
|
|
|
- Stop providing crtassem.h symbols when compiling with Visual Studio 2010, as
|
|
msvcr100.dll is not a platform assembly anymore.
|
|
|
|
- Issue #6508: Add posix.{getresuid,getresgid,setresuid,setresgid}.
|
|
|
|

|
|

- Issue #6877: It is now possible to link the readline extension to the libedit
|
|
readline emulation on OSX 10.5 or later.
|
|
|
|
- Issue #6848: Fix curses module build failure on OS X 10.6.
|
|
|
|
- Fix a segfault that could be triggered by expat with specially formed input.
|
|
|
|
- Issue #6561: '\d' in a regex now matches only characters with Unicode category
|
|
'Nd' (Number, Decimal Digit). Previously it also matched characters with
|
|
category 'No'.
|
|
|
|
- Issue #4509: Array objects are no longer modified after an operation failing
|
|
due to the resize restriction in-place when the object has exported buffers.
|
|
|
|
- Issue #2389: Array objects are now pickled in a portable manner.
|
|
|
|
- Expat: Fix DoS via XML document with malformed UTF-8 sequences
|
|
(CVE_2009_3560).
|
|
|
|
- Issue #7242: On Solaris 9 and earlier calling os.fork() from within a thread
|
|
could raise an incorrect RuntimeError about not holding the import lock. The
|
|
import lock is now reinitialized after fork.
|
|
|
|

- The four path modules (genericpath, macpath, ntpath, posixpath) share a common
|
|
TestCase for some tests: test_genericpath.CommonTest.
|
|
|
|
- Print platform information when running the whole test suite, or using the
|
|
--verbose flag.
|
|
|
|
- Issue #767675: enable test_pep277 on POSIX platforms with Unicode-friendly
|
|
filesystem encoding.
|
|
|
|
- Issue #6292: for the moment at least, the test suite runs cleanly if python is
|
|
run with the -OO flag. Tests requiring docstrings are skipped.
|
|
|
|
- Issue #7712: test.support gained a new `temp_cwd` context manager which is now
|
|
also used by regrtest to run all the tests in a temporary directory. The
|
|
original CWD is saved in `support.SAVEDCWD`. Thanks to Florent Xicluna who
|
|
helped with the patch.
|
|
|
|
- Issue #7924: Fix an intermittent 'XXX undetected error' failure in test_capi
|
|
(only seen so far on platforms where the curses module wasn't built), due to
|
|
an uncleared exception.
|
|
|
|
- Issue #7728: test_timeout was changed to use support.bind_port instead of a
|
|
hard coded port.
|
|
|
|
- Issue #7376: Instead of running a self-test (which was failing) when called
|
|
with no arguments, doctest.py now gives a usage message.
|
|
|
|
- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.
|
|
|
|
- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
|
|
instead of a hardcoded port number in test_rapid_restart.
|
|
|
|
- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
|
|
in the Lib/test directory, which might be read-only for the user running the
|
|
tests.
|
|
|
|
- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
|
|
of an option with no handler.
|
|
|
|
- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
|
|
fails. Can be combined with -j.
|
|
|
|
- Issue #6551: test_zipimport could import and then destroy some modules of the
|
|
encodings package, which would make other tests fail further down the road
|
|
because the internally cached encoders and decoders would point to empty
|
|
global variables.
|
|
|
|
- Issue #7295: Do not use a hardcoded file name in test_tarfile.
|
|
|
|
- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
|
|
primitives such as Lock, RLock, Condition, Event and Semaphore.
|
|
|
|
- Issue #7248 (part 2): Use a unique temporary directory for importlib source
|
|
tests instead of tempfile.tempdir. This prevents the tests from sharing state
|
|
between concurrent executions on the same system.
|
|
|
|
- Issue #7248: In importlib.test.source.util a try/finally block did not make
|
|
sure that some referenced objects actually were created in the block before
|
|
calling methods on the object.
|
|
|
|
- Issue #7222: Make thread "reaping" more reliable so that reference
|
|
leak-chasing test runs give sensible results. The previous method of reaping
|
|
threads could return successfully while some Thread objects were still
|
|
referenced. This also introduces a new private function:
|
|
:func:`_thread._count()`.
|
|
|
|
- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
|
|
runs the risk of causing the worker thread to fail.
|
|
|
|
- Issue #7055: test___all__ now greedily detects all modules which have an
|
|
__all__ attribute, rather than using a hardcoded and incomplete list.
|
|
|
|
- Issue #7058: Added save/restore for things like sys.argv and cwd to
|
|
runtest_inner in regrtest, with warnings if the called test modifies them, and
|
|
a new section in the summary report at the end.
|
|
|
|
- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
|
|
|
|
- Fixed tests in importlib.test.source.test_abc_loader that were masking the
|
|
proper exceptions that should be raised for missing or improper code object
|
|
bytecode.
|
|
|
|
- Removed importlib's custom test discovery code and switched to
|
|
unittest.TestLoader.discover().
|
|
|
|
Tools/Demos
|
|
-----------
|
|
|
|
- Issue #5464, #8974: Implement plural forms in msgfmt.py.
|
|
|
|
- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were
|
|
added to the `Tools/` directory. They were previously living in the sandbox.
|

|
|
- Issue #6137: The pickle module now translates module names when loading
|
|
or dumping pickles with a 2.x-compatible protocol, in order to make data

|
|
- Removed the ipaddr module.
|
|
|
|
- Issue #3613: base64.{encode,decode}string are now called

|
|
|
|
C-API

=============================================
|
|
|
|
*Release date: 2009-05-30*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|

- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
|
|
of the command line.
|
|
|
|
- Issue #6012: Add cleanup support to O& argument parsing.
|
|
|
|
- Issue #6089: Fixed str.format with certain invalid field specifiers
|
|
that would raise SystemError.
|
|
|
|
- Issue #5982: staticmethod and classmethod now expose the wrapped
|
|
function with __func__.
|
|
|
|
- Added support for multiple context managers in the same with-statement.
|
|
Deprecated contextlib.nested() which is no longer needed.
|
|
|
|
- Issue #5829: complex("1e500") no longer raises OverflowError. This
|
|
makes it consistent with float("1e500") and interpretation of real
|
|
and imaginary literals.
|
|
|
|
- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
|
|
|
|
- Issue #5994: the marshal module now has docstrings.
|
|
|
|
- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
|
|
(1) inf and nan strings with trailing whitespace were incorrectly
|
|
rejected; (2) parsing of strings representing infinities and nans
|
|
was locale aware; and (3) the interpretation of fromhex('-nan')
|
|
didn't match that of float('-nan').
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
|
|
|
|
- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
|
|
|
|
- Issue #6121: pydoc now ignores leading and trailing spaces in the
|
|
argument to the 'help' function.
|
|
|
|
- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
|
|
arguments for strings with a space in them.
|
|
|
|
- collections.namedtuple() was not working with the following field
|
|
names: cls, self, tuple, itemgetter, and property.
|
|
|
|
- In unittest, using a skipping decorator on a class is now equivalent to
|
|
skipping every test on the class. The ClassTestSuite class has been removed.
|
|
|
|
- Issue #6050: Don't fail extracting a directory from a zipfile if
|
|
the directory already exists.
|
|
|
|
- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
|
|
than an int, which makes some operations possible under 64-bit Linux (e.g.
|
|
DN_MULTISHOT with F_NOTIFY).
|
|
|
|
- Issue #5761: Add the name of the underlying file to the repr() of various
|
|
IO objects.
|
|
|
|
- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
|
|
by Musashi Tamura, tests by Marcin Bachry.
|
|
|
|
- Issue #1983: Fix functions taking or returning a process identifier to use
|
|
the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
|
|
a process identifier type wider than the standard C integer type.
|
|
|
|
- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
|
|
Patch by Farhan Ahmad, test by Marcin Bachry.
|
|
|
|
- Issue #2116: Weak references and weak dictionaries now support copy()ing and

|
|
|
|
- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
|
|
|
|
- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
|
|
library. This means, for example, that opening an UTF-16 text file in
|
|
append mode doesn't add a BOM at the end of the file if the file isn't
|
|
empty.
|
|
|
|
- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
|
|
file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
|
|
corrects a pydoc regression.
|
|
|
|
- Issue #5955: aifc's close method did not close the file it wrapped,
|
|
now it does. This also means getfp method now returns the real fp.
|
|
|

|
|
- Lib/smtpd.py is no longer installed as a script.
|
|
|

|
- Issue #4873: Fix resource leaks in error cases of pwd and grp.
|
|
|
|
- Issue #6093: Fix off-by-one error in locale.strxfrm.

|
- The _functools and _locale modules are now built into the libpython shared
|
|
library instead of as extension modules.
|
|
|
|
Build
|
|
-----
|
|
|
|
- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file
|
|
and a python3.pc symlink in the $(LIBDIR)/pkgconfig directory. Patch by
|
|
Clinton Roy.
|
|
|
|
Tests
|
|
-----
|
|
|
|
- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
|
|
tests on darwin even when the OS was installed on a case-sensitive
|
|
filesystem. Also fixed tests that should not be run when
|
|
sys.dont_write_bytecode is true.

What's New in Python 3.1 beta 1?
|
|
================================
|
|
|
|
*Release date: 2009-05-06*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Issue #5914: Add new C API function PyOS_string_to_double, and
|
|
deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
|
|
|
|
- Issue #3382: float.__format__, complex.__format__, and %-formatting
|
|
no longer map 'F' to 'f'. Because of issue #5859 (below), this only
|
|
affects nan -> NAN and inf -> INF.
|
|
|
|
- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
|
|
in all operations, including splitdrive, split, etc. splitunc() now issues
|
|
a PendingDeprecation warning.
|
|
|
|
- Issue #5920: For float.__format__, change the behavior with the
|
|
empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
|
|
to be like 'g' but with at least one decimal point and with a
|
|
default precision of 12. Previously, the behavior the same but with
|
|
a default precision of 6. This more closely matches str(), and
|
|
reduces surprises when adding alignment flags to the empty
|
|
presentation type. This also affects the new complex.__format__ in
|
|
the same way.
|
|
|
|
- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
|
|
|
|
- Issue #5890: in subclasses of 'property' the __doc__ attribute was
|
|
shadowed by classtype's, even if it was None. property now
|
|
inserts the __doc__ into the subclass instance __dict__.
|
|
|
|
- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
|
|
sequences. Patch by Nick Barnes and Victor Stinner.
|
|
|
|
- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
|
|
|
|
- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
|
|
received a new method, detach(). detach() disconnects the underlying stream
|
|
from the buffer or text IO and returns it.
|
|
|
|
- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
|
|
floats with absolute value over 1e50. Also remove length
|
|
restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
|
|
12.34 no longer raise an exception.
|
|
|
|
- Issue #1588: Add complex.__format__. For example,
|
|
format(complex(1, 2./3), '.5') now produces a sensible result.
|
|
|
|
- Issue #5864: Fix empty format code formatting for floats so that it
|
|
never gives more than the requested number of significant digits.
|
|
|
|
- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
|
|
new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
|
|
|
|
- Issue #5835: Deprecate PyOS_ascii_formatd.
|
|
|
|
- Issue #4971: Fix titlecase for characters that are their own
|
|
titlecase, but not their own uppercase.
|
|
|
|
- Issue #5283: Setting __class__ in __del__ caused a segfault.
|
|
|
|
- Issue #5816: complex(repr(z)) now recovers z exactly, even when
|
|
z involves nans, infs or negative zeros.
|
|
|
|
- Issue #3166: Make int -> float conversions correctly rounded.
|
|
|
|
- Issue #1869 (and many duplicates): make round(x, n) correctly
|
|
rounded for a float x, by using the decimal <-> binary conversions
|
|
from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
|
|
consistently agrees with format(x, '.2f').
|
|
|
|
- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
|
|
some builtin types.
|
|
|
|
- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
|
|
|
|
- Issue #5515: str.format() type 'n' combined with commas and leading
|
|
zeros no longer gives odd results with ints and floats.
|
|
|
|
- Implement PEP 378, Format Specifier for Thousands Separator, for
|
|
floats.
|
|
|
|
- The str function switches to exponential notation at
|
|
1e11, not 1e12. This avoids printing 13 significant digits in
|
|
situations where only 12 of them are correct. Example problem
|
|
value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
|
|
long time.)
|
|
|
|
- Issue #1580: On most platforms, use a 'short' float repr: for a
|
|
finite float x, repr(x) now outputs a string based on the shortest
|
|
sequence of decimal digits that rounds to x. Previous behaviour was
|
|
to output 17 significant digits and then strip trailing zeros.
|
|
Another minor difference is that the new repr switches to
|
|
exponential notation at 1e16 instead of the previous 1e17; this
|
|
avoids misleading output in some cases.
|
|
|
|
There's a new sys attribute sys.float_repr_style, which takes
|
|
the value 'short' to indicate that we're using short float repr,
|
|
and 'legacy' if the short float repr isn't available for one
|
|
reason or another.
|
|
|
|
The float repr change involves incorporating David Gay's 'perfect
|
|
rounding' code into the Python core (it's in Python/dtoa.c). As a
|
|
secondary consequence, all string-to-float and float-to-string
|
|
conversions (including all float formatting operations) will be
|
|
correctly rounded on these platforms.
|
|
|
|
See issue #1580 discussions for details of platforms for which
|
|
this change does not apply.
|
|
|
|
- Issue #5759: float() didn't call __float__ on str subclasses.
|
|
|
|
- The string.maketrans() function is deprecated; there is a new static method
|
|
maketrans() on the bytes and bytearray classes. This removes confusion about
|
|
the types string.maketrans() is supposed to work with, and mirrors the
|
|
methods available on the str class.
|
|
|
|
- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
|
|
its clarity and its speed.
|
|
|
|
- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
|
|
to avoid compiler warnings.
|
|
|
|
- Issue #3739: The unicode-internal encoder now reports the number of characters
|
|
consumed like any other encoder (instead of the number of bytes).
|
|
|
|
Installation
|
|
------------
|
|
|
|
- Issue #5756: Install idle and pydoc with a 3 suffix.
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #8203: Fix IDLE Credits dialog: view_file() uses its encoding argument.
|
|
|
|
- Issue #5311: bdist_msi can now build packages that do not depend on a
|
|
specific Python version.
|
|
|
|
- Issue #5150: IDLE's format menu now has an option to strip trailing
|
|
whitespace.
|
|

What's New in Python 3.1 alpha 2?
|
|
=================================
|
|
|
|
*Release date: 2009-4-4*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- Implement PEP 378, Format Specifier for Thousands Separator, for
|
|
integers.
|
|
|
|
- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
|
|
|
|
- Issue #5499: The 'c' code for argument parsing functions now only accepts a
|
|
byte, and the 'C' code only accepts a unicode character.
|
|
|
|
- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
|
|
when hitting the recursion limit under certain circumstances.
|
|
|
|
- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
|
|
|
|
- Fix a segfault when running test_exceptions with coverage, caused by
|
|
insufficient checks in accessors of Exception.__context__.
|
|
|
|
- Issue #5604: non-ASCII characters in module name passed to
|
|
imp.find_module() were converted to UTF-8 while the path is
|
|
converted to the default filesystem encoding, causing nonsense.
|
|
|
|
- Issue #5126: str.isprintable() returned False for space characters.
|
|
|
|
- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
|
|
the end sys.path, for compatibility with the system install of Python.
|
|
|
|
- Issue #4688: Add a heuristic so that tuples and dicts containing only
|
|
untrackable objects are not tracked by the garbage collector. This can
|
|
reduce the size of collections and therefore the garbage collection overhead
|
|
on long-running programs, depending on their particular use of datatypes.
|
|
|
|
- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
|
|
improve its performance. Long divisions and remainder operations
|
|
are now between 50% and 150% faster.
|
|
|
|
- Issue #4258: Make it possible to use base 2**30 instead of base
|
|
2**15 for the internal representation of integers, for performance
|
|
reasons. Base 2**30 is enabled by default on 64-bit machines. Add
|
|
--enable-big-digits option to configure, which overrides the
|
|
default. Add sys.int_info structseq to provide information about
|
|
the internal format.
|
|
|
|
- Issue #4474: PyUnicode_FromWideChar now converts characters outside
|
|
the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
|
|
and sizeof(Py_UNICODE) == 2.
|
|
|
|
- Issue #5237: Allow auto-numbered fields in str.format(). For
|
|
example: '{} {}'.format(1, 2) == '1 2'.
|
|
|
|
- Issue #5392: when a very low recursion limit was set, the interpreter would
|
|
abort with a fatal error after the recursion limit was hit twice.
|
|
|
|
- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
|
|
short file names.
|
|
|
|
Library
|
|
-------
|
|
|
|
- Issue #2625: added missing items() call to the for loop in
|
|
mailbox.MH.get_message().
|
|
|
|
- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
|
|
error substitutions from non-strict codec error callbacks in
|
|
incrementalencoder and StreamWriter.
|
|
|
|
- Issue #5656: Fix the coverage reporting when running the test suite with
|
|
the -T argument.
|
|
|
|
- Issue #5647: MutableSet.__iand__() no longer mutates self during iteration.
|
|
|
|
- Issue #5624: Fix the _winreg module name still used in several modules.
|
|
|
|
- Issue #5628: Fix io.TextIOWrapper.read() with a unreadable buffer.
|
|
|
|
- Issue #5619: Multiprocessing children disobey the debug flag and causes
|
|
popups on windows buildbots. Patch applied to work around this issue.
|
|
|
|
- Issue #5400: Added patch for multiprocessing on netbsd compilation/support
|
|
|
|
- Issue #5387: Fixed mmap.move crash by integer overflow.
|
|
|
|
- Issue #5261: Patch multiprocessing's semaphore.c to support context
|
|
manager use: "with multiprocessing.Lock()" works now.
|
|
|
|
- Issue #5236: Change time.strptime() to only take strings. Didn't work with
|
|
bytes already but the failure was non-obvious.
|
|
|
|
- Issue #5177: Multiprocessing's SocketListener class now uses
|
|
socket.SO_REUSEADDR on all connections so that the user no longer needs
|
|
to wait 120 seconds for the socket to expire.
|
|
|
|
- Issue #5595: Fix UnboundedLocalError in ntpath.ismount().
|
|
|
|
- Issue #1174606: Calling read() without arguments of an unbounded file
|
|
(typically /dev/zero under Unix) could crash the interpreter.
|
|
|
|
- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
|
|
io.BufferedRandom have been deprecated for removal in Python 3.2.
|
|
|
|
- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
|
|
forever on incomplete input. That caused tarfile.open() to hang when used
|
|
with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
|
|
partial bzip2 compressed data.
|
|
|
|
- Issue #2110: Add support for thousands separator and 'n' type
|
|
specifier to Decimal.__format__
|
|
|
|
- Fix Decimal.__format__ bug that swapped the meanings of the '<' and
|
|
'>' alignment characters.
|
|
|
|
- The error detection code in FileIO.close() could fail to reflect the `errno`
|
|
value, and report it as -1 instead.
|
|
|
|
- Issue #5016: FileIO.seekable() could return False if the file position
|
|
was negative when truncated to a C int. Patch by Victor Stinner.
|
|
|
|
Extension Modules
|
|
-----------------
|
|
|
|
- Issue #5391: mmap now deals exclusively with bytes.
|
|
|
|
- Issue #5463: In struct module, remove deprecated overflow wrapping
|
|
when packing an integer: struct.pack('=L', -1) now raises
|
|
struct.error instead of returning b'\xff\xff\xff\xff'. The
|
|
_PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
|
|
have been removed from the struct module.
|
|
|
|
|
|
What's New in Python 3.1 alpha 1
|
|
================================
|
|
|
|
*Release date: 2009-03-07*
|
|
|
|
Core and Builtins
|
|
-----------------
|
|
|
|
- The io module has been reimplemented in C for speed.
|
|
|
|
- Give dict views an informative __repr__.
|
|
|
|
- Issue #5247: Improve error message when unknown format codes are
|
|
used when using str.format() with str, int, and float arguments.
|
|
|
|
- Issue #5249: time.strftime returned malformed string when format string
|
|
contained non ascii character on windows.
|
|
|
|
- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
|
|
source has already been decoded into str.
|
|
|
|
- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
|
|
rotating the object pointer by 4 bits to the right.
|
|
|
|
- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
|
|
it now forces its argument to double before testing for infinity.
|
|
|
|
- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
|
|
returns a non-number type.
|
|
|
|
- Issue #5182: Removed memoryview.__str__.
|
|
|
|
- Issue #1717: Removed builtin cmp() function, dropped tp_compare
|
|
slot, the C API functions PyObject_Compare and PyUnicode_Compare and
|
|
the type definition cmpfunc. The tp_compare slot has been renamed
|
|
to tp_reserved, and is reserved for future usage.
|
|
|
|
- Issue #1242657: the __len__() and __length_hint__() calls in several tools
|
|
were suppressing all exceptions. These include list() and bytearray().
|
|
|
|
- Issue #4707: round(x, n) now returns an integer if x is an integer.
|
|
Previously it returned a float.
|
|
|
|
- Issue #4753: By enabling a configure option named '--with-computed-gotos'
|
|
on compilers that support it (notably: gcc, SunPro, icc), the bytecode
|
|
evaluation loop is compiled with a new dispatch mechanism which gives
|
|
speedups of up to 20%, depending on the system, on various benchmarks.
|
|
|
|
- Issue #4874: Most builtin decoders now reject unicode input.
|
|
|
|
- Issue #4842: Don't allow trailing 'L' when constructing an integer
|
|
from a string.
|
|
|
|
- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
|
|
|
|
- Issue #4838: When a module is deallocated, free the memory backing the
|
|
optional module state data.
|
|
|
|
- Issue #4910: Rename nb_long slot to nb_reserved, and change its
|
|
type to ``(void *)``.
|
|
|
|
- Issue #4935: The overflow checking code in the expandtabs() method common
|
|
to str, bytes and bytearray could be optimized away by the compiler, letting
|
|
the interpreter segfault instead of raising an error.
|
|
|
|
- Issue #3720: Fix a crash when an iterator modifies its class and removes its
|
|
__next__ method.
|
|
|
|
- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
|
|
function no longer attempt to call the __long__ slot to convert an object
|
|
to an integer. Only the __int__ and __trunc__ slots are examined.
|
|
|
|
- Issue #4893: Use NT threading on CE.
|
|
|
|
- Issue #4915: Port sysmodule to Windows CE.
|
|
|
|
- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
|
|
common cases are optimized thanks to a dedicated fast path and a moderate
|
|
amount of loop unrolling.
|
|
|
|
- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
|
|
collecting the oldest generation) so that allocating lots of objects without
|
|
destroying them does not show quadratic performance. Based on a proposal by
|
|
Martin von Löwis at
|
|
http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
|
|
|
|
- Issue #4604: Some objects of the I/O library could still be used after
|
|
having been closed (for instance, a read() call could return some
|
|
previously buffered data). Patch by Dmitry Vasiliev.
|
|
|
|
- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
|
|
flag to work properly. Furthermore, when specifying -u, the text stdout
|
|
and stderr streams have line-by-line buffering enabled (the default being
|
|
to buffer arbitrary chunks of data).
|
|
|
|
- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
|
|
instead of ints (reducing its size from 4 to 8 times thereby reducing
|
|
Python's overall memory).
|
|
|
|
- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
|
|
an existing .py counterpart, override the co_filename attributes of all
|
|
code objects if the original filename is obsolete (which can happen if the
|
|
file has been renamed, moved, or if it is accessed through different paths).
|
|
Patch by Ziga Seilnacht and Jean-Paul Calderone.
|
|
|
|
- Issue #4580: Fix slicing of memoryviews when the item size is greater than
|
|
one byte. Also fixes the meaning of len() so that it returns the number of
|
|
items, rather than the size in bytes.
|
|
|
|
- Issue #4075: Use OutputDebugStringW in Py_FatalError.
|
|
|
|
- Issue #4747: When the terminal does not use utf-8, executing a script with
|
|
non-ascii characters in its name could fail with a "SyntaxError: None" error.
|
|
|
|
- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
|
|
to open file with a bytes filename on Windows.
|
|
|
|
- Issue #3680: Reference cycles created through a dict, set or deque iterator
|
|
did not get collected.
|
|
|
|
- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
|
|
where the tp_hash and tp_dict slots are both NULL.
|
|
|
|
- Issue #4759: None is now allowed as the first argument of
|
|
bytearray.translate(). It was always allowed for bytes.translate().
|
|
|
|
- Added test case to ensure attempts to read from a file opened for writing
|
|
fail.
|
|
|
|
- Issue #3106: Speedup some comparisons (str/str and int/int).
|
|
|
|
- Issue #2183: Simplify and optimize bytecode for list, dict and set
|
|
comprehensions. Original patch for list comprehensions by Neal Norwitz.
|
|
|
|
- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
|
|
print elapsed times, not only when some objects are uncollectable /
|
|
unreachable. Original patch by Neil Schemenauer.
|
|
|
|
- Issue #3439: Add a bit_length method to int.
|
|
|
|
- Issue #2173: When getting device encoding, check that return value of
|
|
nl_langinfo is not the empty string. This was causing silent build
|
|
failures on OS X.
|
|
|
|
- Issue #4597: Fixed several opcodes that weren't always propagating
|
|
exceptions.
|
|
|
|
- Issue #4589: Fixed exception handling when the __exit__ function of a
|
|
context manager returns a value that cannot be converted to a bool.
|
|
|
|
- Issue #4445: Replace "sizeof(PyBytesObject)" with
|
|
"offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
|
|
bytes instances. On a typical machine this saves 3 bytes of memory
|
|
(on average) per allocation of a bytes instance.
|
|
|
|
- Issue #4533: File read operation was dreadfully slow due to a slowly
|
|
growing read buffer. Fixed by using the same growth rate algorithm as
|
|
Python 2.x.
|
|
|
|
- Issue #4509: Various issues surrounding resize of bytearray objects to
|
|
which there are buffer exports (e.g. memoryview instances).
|
|
|
|
- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
|
|
method on file objects with closefd=False. The file descriptor is still
|
|
kept open but the file object behaves like a closed file. The ``FileIO``
|
|
object also got a new readonly attribute ``closefd``.
|
|
|
|
- Issue #4569: Interpreter crash when mutating a memoryview with an item size
|
|
larger than 1.
|
|
|
|
- Issue #4748: Lambda generators no longer return a value.
|
|
|
|
- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
|
|
|
|
- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
|
|
PyUnicode_DecodeUTF8() once, remember the result and output it in a second
|
|
step. This avoids problems with counting UTF-8 bytes that ignores the effect
|
|
of using the replace error handler in PyUnicode_DecodeUTF8().
|
|
|
|

- Issue #7071: byte-compilation in Distutils is now done with respect to
|
|
sys.dont_write_bytecode.

|
|
|
|
- Issue #6545: Removed assert statements in distutils.Extension, so the
|
|
behavior is similar when used with -O.
|
|
|
|
- unittest has been split up into a package. All old names should still work.
|
|
|
|
- Issue #6466: now distutils.cygwinccompiler and distutils.emxccompiler
|
|
uses the same refactored function to get gcc/ld/dllwrap versions numbers.
|
|
It's `distutils.util.get_compiler_versions`. Added deprecation warnings
|
|
for the obsolete get_versions() functions.
|
|

Extension Modules
|
|
-----------------
|
|
|
|
- Issue #3745: Fix hashlib to always reject unicode and non buffer-api
|
|
supporting objects as input no matter how it was compiled (built in
|
|
implementations or external openssl library).
|
|
|
|
- Issue #4397: Fix occasional test_socket failure on OS X.
|
|
|
|
- Issue #4279: Fix build of parsermodule under Cygwin.
|
|
|
|
- Issue #4751: hashlib now releases the GIL when hashing large buffers
|
|
(with a hardwired threshold of 2048 bytes), allowing better parallelization
|
|
on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.
|
|
|
|
- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
|
|
|
|
- Issue #4738: Each zlib object now has a separate lock, allowing to compress
|
|
or decompress several streams at once on multi-CPU systems. Also, the GIL
|
|
is now released when computing the CRC of a large buffer. Patch by ebfe.
|
|
|
|
- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.
|
|
|
|
- Issue #1040026: Fix os.times result on systems where HZ is incorrect.
|
|
|
|
- Issues #3167, #3682: Fix test_math failures for log, log10 on Solaris,
|
|
OpenBSD.
|
|
|
|
- Issue #4583: array.array would not always prohibit resizing when a buffer
|
|
has been exported, resulting in an interpreter crash when accessing the
|
|
buffer.
|
|
|
|
|
|
- Issue #5228: Make functools.partial objects can now be pickled.
|
|
|
|
Tests
|
|
-----
|
|
|
|
- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
|
|
regression tests in parallel, shortening the total runtime.
|
|
|
|
- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
|
|
Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
|
|
the same behaviour as test_ttkguionly (and now also test_tk) which is to
|
|
skip the tests if DISPLAY is defined but can't be used.
|
|
|
|
- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
|
|
that should cause a test to be skipped are now done using import_module
|
|
from test support, which does the conversion.
|
|
|
|
- Issue #5083: New 'gui' resource for regrtest.
