What's New in Python 3.2 Beta 1?
2010-10-12 20:38:48 +08:00
================================
2010-10-12 06:38:01 +08:00
2010-10-12 20:38:48 +08:00
*Release date: XX-Nov-2010*
2010-10-12 06:38:01 +08:00
Core and Builtins
-----------------
- Issue #6081: Add str.format_map, similar to str.format(**mapping).
2010-10-31 07:16:28 +08:00
- 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 hold 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 #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 #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 (eg. PyParser_ASTFromFile) expects
filenames encoded to the filesystem encoding with 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, reuse instead 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.
2010-10-12 06:38:01 +08:00
Library
-------
- Issue #10155: Add IISCGIHandler to wsgiref.handlers to support IIS
CGI 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.
- Issue #10184: Touch directories only once when extracting a tarfile.
- Issue #10199: New package, ``turtledemo`` now contains selected demo
scripts that were formerly found under Demo/turtle.
- Issue #10265: Close file objects explicitly in sunau. Patch by Brian Brazil.
- Issue #10266: uu.decode didn't close in_file explicitly when it was given
as a filename. Patch by Brian Brazil.

maxsize parameter had been reduced.
- Issue #10160: Speed up operator.attrgetter. Patch by Christos Georgiou.
- logging: Added style option to basicConfig() to allow %, {} or $-formatting.
- Issue #5729: json.dumps() now supports using a string such as '\t'
for pretty-printing multilevel objects.
- Issue #10253: FileIO leaks a file descriptor when trying to open a file
for append that isn't seekable. Patch by Brian Brazil.
- Support context manager protocol for file-like objects returned by
mailbox ``get_file()`` methods.
- Issue #10246: uu.encode didn't close file objects explicitly when filenames
were given to it. Patch by Brian Brazil.
- Issue #10198: fix duplicate header written to wave files when writeframes()
is called without data.
- Close file objects in modulefinder in a timely manner.
- Close a io.TextIOWrapper object in email.parser in a timely manner.
- Close a file object in distutils.sysconfig in a timely manner.
- Close a file object in pkgutil in a timely manner.
- Issue #10233: Close file objects in a timely manner in the tarfile module
and its test suite.
- Issue #10093: ResourceWarnings are now issued when files and sockets are
deallocated without explicit closing. These warnings are silenced by
default, except in pydebug mode.
- tarfile.py: Add support for all missing variants of the GNU sparse
extensions and create files with holes when extracting sparse members.
- Issue #10218: Return timeout status from ``Condition.wait`` in threading.
- Issue #7351: Add ``zipfile.BadZipFile`` spelling of the exception name
and deprecate the old name ``zipfile.BadZipfile``.
- Issue #5027: The standard ``xml`` namespace is now understood by
xml.sax.saxutils.XMLGenerator as being bound to
http://www.w3.org/XML/1998/namespace. Patch by Troy J. Farrell.
2010-10-27 15:27:06 +08:00
- Issue #5975: Add csv.unix_dialect class.
- Issue #7761: telnetlib.interact failures on Windows fixed.
- logging: Added style option to Formatter to allow %, {} or $-formatting.
- Issue #5178: Added tempfile.TemporaryDirectory class that can be used
as a context manager.
- Issue #1349106: Generator (and BytesGenerator) flatten method and Header
encode method now support a 'linesep' argument.
- Issue #5639: Add a *server_hostname* argument to ``SSLContext.wrap_socket``
in order to support the TLS SNI extension. ``HTTPSConnection`` and
``urlopen()`` also use this argument, so that HTTPS virtual hosts are now
supported.
- Issue #10166: Avoid recursion in pstats Stats.add() for many stats items.
- Issue #10163: Skip unreadable registry keys during mimetypes
initialization.
- logging: Made StreamHandler terminator configurable.
- logging: Allowed filters to be just callables.
- logging: Added tests for _logRecordClass changes.
- Issue #10092: Properly reset locale in calendar.Locale*Calendar classes.
- logging: Added _logRecordClass, getLogRecordClass, setLogRecordClass to
increase flexibility of LogRecord creation.
- Issue #5117: Case normalization was needed on ntpath.relpath(). And
fixed root directory issue on posixpath.relpath(). (Ported working fixes
from ntpath)
- Issue #1343: xml.sax.saxutils.XMLGenerator now has an option
short_empty_elements to direct it to use self-closing tags when appropriate.
2010-10-16 09:20:45 +08:00

- Issue #5762: Fix AttributeError raised by ``xml.dom.minidom`` when an empty
XML namespace attribute is encountered.
- Issue #2830: Add the ``html.escape()`` function, which quotes all problematic
characters by default. Deprecate ``cgi.escape()``.
2010-10-16 00:42:14 +08:00
- Issue #9409: Fix the regex to match all kind of filenames, for interactive
debugging in doctests.
2010-10-16 00:42:14 +08:00
- Issue #9183: ``datetime.timezone(datetime.timedelta(0))`` will now
2010-10-15 01:03:51 +08:00
return the same instance as ``datetime.timezone.utc``.
- Issue #7523: Add SOCK_CLOEXEC and SOCK_NONBLOCK to the socket module,
where supported by the system. Patch by Nikita Vetoshkin.
- Issue #10063: file:// scheme will stop accessing remote hosts via ftp
protocol. file:// urls had fallback to access remote hosts via ftp. This was
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
created in modes 'a' or 'w' and then closed without adding any files. Raise
BadZipfile (rather than IOError) when opening small non-ZIP files.
- Issue #10041: The signature of optional arguments in socket.makefile()
didn't match that of io.open(), and they also didn't get forwarded
properly to TextIOWrapper in text mode. Patch by Kai Zhu.
- Issue #9003: http.client.HTTPSConnection, urllib.request.HTTPSHandler and

server certificate checking, as recommended in public uses of HTTPS.
2010-10-13 06:42:37 +08:00
- Issue #6612: Fix site and sysconfig to catch os.getcwd() error, eg. if the
current directory was deleted. Patch written by W. Trevor King.
- Issue #3873: Speed up unpickling from file objects which have a peek()
method.
- Issue #10075: Add a session_stats() method to SSLContext objects.
2010-10-12 06:38:01 +08:00

What's New in Python 3.2 Alpha 3?
=================================
2010-10-10 17:40:34 +08:00
*Release date: 09-Oct-2010*
2010-09-06 05:29:17 +08:00
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()
2010-10-10 17:49:21 +08:00
encodings.
2010-10-10 17:49:21 +08:00
- 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).
2010-10-02 19:50:49 +08:00
- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
2010-10-10 17:49:21 +08:00
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.
2010-10-10 17:49:21 +08:00
- 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.)
2010-10-10 17:49:21 +08:00
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.
2010-09-22 05:28:47 +08:00
- 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().
2010-10-10 17:49:21 +08:00
- 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.
2010-10-10 17:49:21 +08:00
- Issue #9212: The range type_items now provides index() and count() methods, to
conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
2010-10-10 17:49:21 +08:00
- 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.
2010-10-10 17:49:21 +08:00
- 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).
2010-10-10 17:49:21 +08:00
- 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.
2010-09-06 05:29:17 +08:00
Library
-------
- 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.
2010-10-05 08:04:20 +08:00
- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
returning a (sock, addr) pair which is called when a connection has been
2010-10-10 17:49:21 +08:00
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.
2010-10-10 17:49:21 +08:00
- 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.
2010-10-10 17:49:21 +08:00
- Issue #10004: quoprimime no longer generates a traceback when confronted with
invalid characters after '=' in a Q-encoded word.
2010-10-10 17:49:21 +08:00
- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
sending a 200 OK for the Expect: 100-continue request header.
2010-10-10 17:49:21 +08:00
- 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,
2010-10-10 17:49:21 +08:00
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
2010-10-10 17:49:21 +08:00
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.
2010-10-10 17:49:21 +08:00
- 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.
2010-09-22 05:28:47 +08:00
- 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().
2010-10-10 17:49:21 +08:00
- 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
2010-10-10 17:49:21 +08:00
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.
2010-10-10 17:49:21 +08:00
- Issue #9865: collections.OrderedDict now has a __sizeof__ method.
2010-10-10 17:49:21 +08:00
- Issue #9854: The default read() implementation in io.RawIOBase now handles
non-blocking readinto() returning None correctly.
2010-10-10 17:49:21 +08:00
- Issue #1552: socket.socketpair() now returns regular socket.socket objects
supporting the whole socket API (rather than the "raw" _socket.socket
objects).
2010-10-10 17:49:21 +08:00
- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
to match the corresponding socket methods.
2010-10-10 17:49:21 +08:00
- Issue 9840: Added a decorator to reprlib for wrapping __repr__ methods to make
them handle recursive calls within the same thread.
2010-09-14 04:40:30 +08:00
- 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.
2010-10-10 17:49:21 +08:00
- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
d['x'] = d.
- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
2010-10-10 17:49:21 +08:00
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
2010-10-10 17:49:21 +08:00
utf-8 in strict mode) . Patch written by David Watson.
2010-10-10 17:49:21 +08:00
- 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.
2010-10-10 17:49:21 +08:00
- 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.
2010-10-10 17:49:21 +08:00
- The pprint module now supports printing OrderedDicts in their given order
(formerly, it would sort the keys).
2010-09-08 18:46:15 +08:00
- Logging: Added QueueHandler class to facilitate logging usage with
multiprocessing.
2010-10-10 17:49:21 +08:00
- 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.
2010-10-10 17:49:21 +08:00
- 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.
2010-10-10 17:49:21 +08:00
- 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:
2010-10-10 17:49:21 +08:00
* Document which parts of the module are guaranteed to stay the same across
versions and which parts are subject to change.
2010-10-10 17:49:21 +08:00
* 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.
2010-10-10 17:49:21 +08:00
* 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.
2010-10-10 17:49:21 +08:00
- collections.OrderedDict now supports a new method for repositioning keys to

What's New in Python 3.2 Alpha 2?
=================================
2010-09-05 16:30:40 +08:00
*Release date: 05-Sep-2010*
2010-08-01 02:05:35 +08:00
Core and Builtins
-----------------
2010-09-06 01:06:50 +08:00
- 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.
2010-09-06 01:06:50 +08:00
- Issue #9212: dict_keys and dict_items now provide the isdisjoint() method, to
conform to the Set ABC. Patch by Daniel Urban.
2010-09-06 01:06:50 +08:00
- Issue #9737: Fix a crash when trying to delete a slice or an item from a
memoryview object.
2010-09-06 01:06:50 +08:00
- 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.
2010-09-06 01:06:50 +08:00
- 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.
2010-09-06 01:06:50 +08:00
- Issue #9684: Added a definition for SIZEOF_WCHAR_T to PC/pyconfig.h, to match
the pyconfig.h generated by configure on other systems.
2010-09-06 01:06:50 +08:00
- 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.
2010-09-06 01:06:50 +08:00
- 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.
2010-09-06 01:06:50 +08:00
- 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:
2010-09-06 01:06:50 +08:00
decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
objects are output as-is.
2010-09-06 01:06:50 +08:00
- 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.
2010-09-06 01:06:50 +08:00
- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
use PyUnicode_FromFormatV() to format the warning message.
2010-09-06 01:06:50 +08:00
- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
array.
2010-09-06 01:06:50 +08:00
- Issue #5319: Print an error if flushing stdout fails at interpreter shutdown.
2010-09-06 01:06:50 +08:00

repr().
2010-09-06 01:06:50 +08:00

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.

What's New in Python 3.2 Alpha 1?
=================================
2010-07-31 16:56:11 +08:00
*Release date: 01-Aug-2010*
2009-06-28 05:40:27 +08:00
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
2010-07-31 16:56:11 +08:00
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'.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
Fix the encoding of the modules filename. Patch written by Amaury Forgeot
d'Arc.
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
mode raises unicode errors. The encoder only supports "strict" and "replace"
error handlers, the decoder only supports "strict" and "ignore" error
2010-07-31 16:56:11 +08:00
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"
2010-07-31 16:56:11 +08:00
formats if the string contains a null byte/character. Write unit tests for
string formats.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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).
2010-07-31 16:56:11 +08:00
- 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().
2010-07-31 16:56:11 +08:00
- 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*"
2010-07-31 16:56:11 +08:00
instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
like bytearray.
2010-07-31 16:56:11 +08:00
- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
used anymore and it was never documented.
2010-07-31 16:56:11 +08:00
- In str.format(), raise a ValueError when indexes to arguments are too large.
2010-07-31 16:56:11 +08:00
- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
integers n (including n = -909).
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
(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
2010-07-31 16:56:11 +08:00
be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
2010-05-16 01:43:57 +08:00
back to UTF-8.
- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
2010-07-31 16:56:11 +08:00
error handler, not only the default error handler (strict).
- Issue #8610: Load file system codec at startup, and display a fatal error on
2010-07-31 16:56:11 +08:00
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
2010-07-31 16:56:11 +08:00
PyUnicode_FromString() to support surrogates in the filename and use the right
encoding.

2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
indirectly Python signal handlers anymore because mywrite() ignores exceptions
(KeyboardInterrupt).
- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
2010-07-31 16:56:11 +08:00
unicode string (eg. backslashreplace).
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
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.
2010-07-31 16:56:11 +08:00
- 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.

- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
2010-07-31 16:56:11 +08:00
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
2010-07-31 16:56:11 +08:00
printed and Python exits. Initialize the GIL before importing the site module.
- Issue #7173: Generator finalization could invalidate sys.exc_info().
2010-07-31 16:56:11 +08:00
- Issue #7544: Preallocate thread memory before creating the thread to avoid a
fatal error in low memory condition.
2010-07-31 16:56:11 +08:00

Now it matches other numeric types.
- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
2010-07-31 16:56:11 +08:00
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.
2010-07-31 16:56:11 +08:00
- Issue #7385: Fix a crash in `MemoryView_FromObject` when `PyObject_GetBuffer`
fails. Patch by Florent Xicluna.
2010-07-31 16:56:11 +08:00

- 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.
2010-07-31 16:56:11 +08:00
- 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}`,
2010-07-31 16:56:11 +08:00
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.
2010-07-31 16:56:11 +08:00
- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
in ** operator. The behaviour now conforms to that described in C99 Annex F.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
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).
2010-07-31 16:56:11 +08:00
- 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.

mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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.

libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
will be entirely removed in 3.3.
2010-05-04 05:18:48 +08:00
- Support for OSF* has been disabled. If nobody stands up, support will be
2010-07-31 16:56:11 +08:00
removed in 3.3. See <http://bugs.python.org/issue8606>.
2010-05-04 05:18:48 +08:00
- 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.
2010-07-31 16:56:11 +08:00

in GAE.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when using
byte values greater than 127. Patch by Derk Drukker.

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.
2010-07-31 16:56:11 +08:00

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.

and not an int. Fix the corresponding error message, and the documentation.
2009-07-01 09:28:55 +08:00
- The deprecated PyCObject has been removed.
2010-07-31 16:56:11 +08:00
- 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 #4856: Remove checks for win NT.
2010-07-31 16:56:11 +08:00
- Issue #6687: PyBytes_FromObject() no longer accepts an integer as its argument
to construct a null-initialized bytes object.
2010-07-31 16:56:11 +08:00
- Issue #1023290: Add from_bytes() and to_bytes() methods to integers. These
methods allow the conversion of integers to bytes, and vice-versa.
2010-07-31 16:56:11 +08:00
- Issue #7382: Fix bug in bytes.__getnewargs__ that prevented bytes instances
from being copied with copy.copy(), and bytes subclasses from being pickled
properly.
2010-01-12 09:23:09 +08:00
- Code objects now support weak references.
2010-07-31 16:56:11 +08:00
- Issue #7072: isspace(0xa0) is true on Mac OS X.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
function declaration, which was kept for backwards compatibility reasons, is
now removed (the macro was introduced in 1997!).
2010-07-31 16:56:11 +08:00
- 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,
2010-07-31 16:56:11 +08:00
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.
2010-07-31 16:56:11 +08:00
- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.
2010-07-31 16:56:11 +08:00
- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments) in
PyArg_ParseTupleAndKeywords.
2010-07-31 16:56:11 +08:00
- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V) and
PyErr_Format, on machines with HAVE_LONG_LONG defined.
2010-07-31 16:56:11 +08:00
- 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
accessing the d_type and d_name members of structures using PyDescr_COMMON.
- Issue #6405: Remove duplicate type declarations in descrobject.h.
2009-07-03 21:30:25 +08:00
- The code flags for old __future__ features are now available again.

This patch adds a PyCode_NewEmpty wrapper which lets the user specify just the filename, function name, and first line number, instead of also requiring lots of code internals. ........ r72488 | jeffrey.yasskin | 2009-05-08 18:23:21 -0400 (Fri, 08 May 2009) | 13 lines Issue 5954, PyFrame_GetLineNumber: Most uses of PyCode_Addr2Line (http://www.google.com/codesearch?q=PyCode_Addr2Line) are just trying to get the line number of a specified frame, but there's no way to do that directly. Forcing people to go through the code object makes them know more about the guts of the interpreter than they should need. The remaining uses of PyCode_Addr2Line seem to be getting the line from a traceback (for example, http://www.google.com/codesearch/p?hl=en#u_9_nDrchrw/pygame-1.7.1release/src/base.c&q=PyCode_Addr2Line), which is replaced by the tb_lineno field. So we may be able to deprecate PyCode_Addr2Line entirely for external use. ........ r72879 | jeffrey.yasskin | 2009-05-23 19:23:01 -0400 (Sat, 23 May 2009) | 14 lines Issue #6042: lnotab-based tracing is very complicated and isn't documented very well. There were at least 3 comment blocks purporting to document co_lnotab, and none did a very good job. This patch unifies them into Objects/lnotab_notes.txt which tries to completely capture the current state of affairs. I also discovered that we've attached 2 layers of patches to the basic tracing scheme. The first layer avoids jumping to instructions that don't start a line, to avoid problems in if statements and while loops. The second layer discovered that jumps backward do need to trace at instructions that don't start a line, so it added extra lnotab entries for 'while' and 'for' loops, and added a special case for backward jumps within the same line. I replaced these patches by just treating forward and backward jumps differently. ........
2009-07-21 12:30:03 +08:00
- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
PyCode_Addr2Line().
- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
object at a specified file, function, and line number.
- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
``const char *`` as the string is stored beyond the call.
2010-07-31 16:56:11 +08:00
- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
allocator will be automatically disabled when running under Valgrind. This
gives improved memory leak detection when running under Valgrind, while taking
advantage of pymalloc at other times.

- Issue #9384: ``python -m tkinter`` will now display a simple demo applet.
2010-07-31 16:56:11 +08:00
- 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
2010-08-14 00:27:38 +08:00
simply clearing the entire cache on overflow to forgetting the least recently
used cached compiled regular expressions. This is a performance win for
2010-07-31 16:56:11 +08:00
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.

raises an exception.
- Issue #9110: Addition of ContextDecorator to contextlib, for creating APIs
2010-07-31 16:56:11 +08:00
that act as both context managers and decorators. contextmanager changes to
use ContextDecorator.
Implement importlib.abc.SourceLoader and deprecate PyLoader and PyPycLoader. SourceLoader is a simplification of both PyLoader and PyPycLoader. If one only wants to use source, then they need to only implement get_data and get_filename. To also use bytecode -- sourceless loading is not supported -- then two abstract methods -- path_mtime and set_data -- need to be implemented. Compared to PyLoader and PyPycLoader, there are less abstract methods introduced and bytecode files become an optimization controlled by the ABC and hidden from the user (this need came about as PEP 3147 showed that not treating bytecode as an optimization can cause problems for compatibility). PyLoader is deprecated in favor of SourceLoader. To be compatible from Python 3.1 onwards, a subclass need only use simple methods for source_path and is_package. Otherwise conditional subclassing based on whether Python 3.1 or Python 3.2 is being is the only change. The documentation and docstring for PyLoader explain what is exactly needed. PyPycLoader is deprecated also in favor of SourceLoader. Because PEP 3147 shifted bytecode path details so much, there is no foolproof way to provide backwards-compatibility with SourceLoader. Because of this the class is simply deprecated and users should move to SourceLoader (and optionally PyLoader for Python 3.1). This does lead to a loss of support for sourceless loading unfortunately. At some point before Python 3.2 is released, SourceLoader will be moved over to importlib._bootstrap so that the core code of importlib relies on the new code instead of the old PyPycLoader code. This commit is being done now so that there is no issue in having the API in Python 3.1a1.

larger than 1GB with the zlib module's compressor and decompressor objects.
2010-05-07 06:29:53 +08:00
- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
file system encoding with the surrogateescape error handler (instead of
utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
- Issue #8573: asyncore _strerror() function might throw ValueError.
2010-07-31 16:56:11 +08:00
- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
messages when accessing undefined class attributes because of the cheap
inheritance with the underlying socket object. The cheap inheritance has been
deprecated.
- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
Patch by Tres Seaver.
- Issue #8390: tarfile uses surrogateescape as the default error handler
2010-07-31 16:56:11 +08:00
(instead of replace in read mode or strict in write mode).
- Issue #7755: Use an unencumbered audio file for tests.
2010-07-31 16:56:11 +08:00
- Issue #8621: uuid.uuid4() returned the same sequence of values in the parent
and any children created using ``os.fork`` on MacOS X 10.6.
2010-07-31 16:56:11 +08:00
- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
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 #7865: The close() method of :mod:`io` objects should not swallow
2010-07-31 16:56:11 +08:00
exceptions raised by the implicit flush(). Also qensure that calling close()
several times is supported. Patch by Pascal Chambon.
- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
gc.DEBUG_STATS.
2010-07-31 16:56:11 +08:00
- Issue #8354: The siginterrupt setting is now preserved for all signals, not
just SIGCHLD.
- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does
webbrowser.get("safari").
2010-07-31 16:56:11 +08:00

- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
the method could block indefinitely if called just before the event loop
started running. This also fixes the occasional freezes witnessed in
test_httpservers.
2010-07-31 16:56:11 +08:00
- Issue #8524: When creating an SSL socket, the timeout value of the original
socket wasn't retained (instead, a socket with a positive timeout would be
turned into a non-blocking SSL socket).
- Issue #5103: SSL handshake would ignore the socket timeout and block
indefinitely if the other end didn't respond.
2010-07-31 16:56:11 +08:00
- The do_handshake() method of SSL objects now adjusts the blocking mode of the
SSL structure if necessary (as other methods already do).
2010-07-31 16:56:11 +08:00
- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and
bytes strings for environment keys and values.
- Issue #8467: Pure Python implementation of subprocess encodes the error
message using surrogatepass error handler to support surrogates in the
2010-07-31 16:56:11 +08:00
message.
2010-07-31 16:56:11 +08:00
- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames.
2010-07-31 16:56:11 +08:00
- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
string "python" as the *ident*. openlog() arguments are all optional and
keywords.
2010-07-31 16:56:11 +08:00
- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
non-infinite timeout. Also make that method friendlier with applications
wanting to continue using the socket in clear-text mode, by disabling
OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
- Issue #8496: make mailcap.lookup() always return a list, rather than an
iterator. Patch by Gregory Nofi.

2010-07-31 16:56:11 +08:00
- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
module now takes an optional timeout argument in seconds. Timeout support
2010-07-31 16:56:11 +08:00
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
2010-07-31 16:56:11 +08:00
Python 2.x and 3.x.
- Issue #7585: difflib context and unified diffs now place a tab between
2010-07-31 16:56:11 +08:00
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
2010-07-31 16:56:11 +08:00
character sets will now consistently use a Content-Transfer-Encoding of 7bit
rather than sometimes being marked as 8bit.

2010-07-31 16:56:11 +08:00
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().
2010-07-31 16:56:11 +08:00
- 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')
2010-07-31 16:56:11 +08:00
- Issue #8294: The Fraction constructor now accepts Decimal and float instances
directly.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
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
2010-07-31 16:56:11 +08:00
Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
didn't support chflags() (for example ZFS under FreeBSD). The error is now
silenced.
2010-07-31 16:56:11 +08:00
- Issue #7860: platform.uname now reports the correct 'machine' type when Python
is running in WOW64 mode on 64 bit Windows.
2010-03-27 03:36:14 +08:00

an extension module (_posixsubprocess) so that the fork()+exec() can be done
safely without the possibility of deadlock in multithreaded applications.
2010-07-31 16:56:11 +08:00
- 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.
- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to
2010-07-31 16:56:11 +08:00

- Issue #7361: Importlib was not properly checking the number of bytes in
bytecode file when it was less then 8 bytes.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- Issue #6233: ElementTree failed converting unicode characters to XML entities
when they could't be represented in the requested output encoding. Patch by

specified, rather than fall through to AF_PACKET (in the `socket` module).
2010-07-31 16:56:11 +08:00
Also, raise ValueError rather than TypeError when an unknown TIPC address type
is specified. Patch by Brian Curtin.
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
: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,
2010-07-31 16:56:11 +08:00
allowing for a maximum number of tasks within the pool to be completed by the
worker before that worker is terminated, and a new one created to replace it.

2010-07-31 16:56:11 +08:00
properly handles EINTR within the read, readline, write & flush methods. The
socket.sendall() method now properly handles interrupted system calls.
2010-07-31 16:56:11 +08:00
- Issue #7471: Improve the performance of GzipFile's buffering mechanism, and
make it implement the `io.BufferedIOBase` ABC to allow for further speedups by

expressions.
2010-07-31 16:56:11 +08:00
- 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

2010-07-31 16:56:11 +08:00
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
2010-07-31 16:56:11 +08:00
implicit context too. This affects the `traceback` module as well as built-in
exception printing.

registry under Windows. Patch by Gabriel Genellina.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
unpickled. This fixes crashes under Windows when trying to run

- 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
2010-07-31 16:56:11 +08:00
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).
2010-07-31 16:56:11 +08:00
- Issue #7282: Fix a memory leak when an RLock was used in a thread other than

modification is done through it. This fixes inconsistencies and test failures
on systems with slightly bogus mtime behaviour.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- Issue #7233: Fix a number of two-argument Decimal methods to make sure that

- Issue #6838: Use a list to accumulate the value instead of repeatedly
concatenating strings in http.client's HTTPResponse._read_chunked providing a
significant speed increase when downloading large files servend with a
Transfer-Encoding of 'chunked'.
- Trying to import a submodule from a module that is not a package, ImportError
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.
- Raise a TypeError when the name of a module to be imported for
2010-07-31 16:56:11 +08:00

- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
2010-07-31 16:56:11 +08:00
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.
2010-07-31 16:56:11 +08:00
- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

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
2010-07-31 16:56:11 +08:00
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.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-18 15:48:20 +08:00
2010-07-31 16:56:11 +08:00
- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x python when
they contain instances of old-style classes.
2010-07-31 16:56:11 +08:00
- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to accompany
existing isinf and isnan functions.
2010-07-31 16:56:11 +08:00

object in the '?' format.
- Issue #9000: datetime.timezone objects now have eval-friendly repr.
2010-07-02 21:46:42 +08:00
- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
special methods.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
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.
2010-07-31 16:56:11 +08:00
- Issue #8973: Add __all__ to struct module; this ensures that help(struct)
includes documentation for the struct.Struct class.
2010-06-13 01:18:45 +08:00
- Issue #3129: Trailing digits in struct format string are no longer ignored.
For example, "1" or "ilib123" are now invalid formats and cause
2010-06-13 01:18:45 +08:00
``struct.error`` to be raised. Patch by Caleb Deveraux.
2010-07-31 16:56:11 +08:00
- 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.
2010-06-08 22:00:52 +08:00
2010-07-31 16:56:11 +08:00

requiring a re-try in order to get the complete result.
2010-07-31 16:56:11 +08:00
- 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):
2010-07-31 16:56:11 +08:00
the result is now always correctly rounded, and is equivalent to ``td /
timedelta(seconds=1)``.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00

2010-07-31 16:56:11 +08:00
- 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'.
2010-07-31 16:56:11 +08:00
- 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.

(Optimization was unintentionally turned on in gcc --with-pydebug builds as a
result of the issue #1628484 fix, combined with autoconf's strange choice of
default CFLAGS produced by AC_PROG_CC for gcc.)
2010-07-31 16:56:11 +08:00

support. Patches written by Jerry Seutter.
2010-07-31 16:56:11 +08:00
- Issue #8108: test_ftplib's non-blocking SSL server now has proper handling of
SSL shutdowns.
2010-07-31 16:56:11 +08:00
- Issues #8279, #8330, #8437, #8480, #8495: Fix test_gdb failures, patch written
by Dave Malcolm.
2010-07-31 16:56:11 +08:00
- Issue #3864: Skip three test_signal tests on freebsd6 because they fail if any
thread was previously started, most likely due to a platform bug.
- Issue #8193: Fix test_zlib failure with zlib 1.2.4.
- Issue #8248: Add some tests for the bool type. Patch by Gregory Nofi.
- Issue #8263: Now regrtest.py will report a failure if it receives a
KeyboardInterrupt (SIGINT).
- Issue #8180 and #8207: Fix test_pep277 on OS X and add more tests for special
Unicode normalization cases.
2010-07-31 16:56:11 +08:00
- Issue #7783: test.support.open_urlresource invalidates the outdated files from
the local cache.
- Issue #7849: Now the utility ``check_warnings`` verifies if the warnings are
effectively raised.
2010-07-31 16:56:11 +08:00
- The four path modules (genericpath, macpath, ntpath, posixpath) share a common
TestCase for some tests: test_genericpath.CommonTest.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- 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.
2009-12-15 07:06:11 +08:00
- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
instead of a hardcoded port number in test_rapid_restart.
2010-07-31 16:56:11 +08:00
- 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.
2010-07-31 16:56:11 +08:00
- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
of an option with no handler.
2010-07-31 16:56:11 +08:00
- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
fails. Can be combined with -j.
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
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()`.
2010-07-31 16:56:11 +08:00
- 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.
2009-10-19 06:18:17 +08:00
- Issue #7058: Added save/restore for things like sys.argv and cwd to
2010-07-31 16:56:11 +08:00
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.
2010-07-31 16:56:11 +08:00
- 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
2010-07-31 16:56:11 +08:00
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
2010-07-31 16:56:11 +08:00

- 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').
2009-05-07 07:26:59 +08:00
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

- 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.
2010-08-02 06:31:05 +08:00
- 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.
Installation
------------
- Issue #6047: fullinstall has been removed because Python 3's executable will
now be known as python3.
2009-05-07 07:26:59 +08:00

Clinton Roy.
Tests
-----
2010-08-02 06:31:05 +08:00
- 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.
2009-04-05 07:16:41 +08:00
What's New in Python 3.1 beta 1?
================================
2009-05-07 04:43:28 +08:00
*Release date: 2009-05-06*
2009-04-05 07:16:41 +08:00
Core and Builtins
-----------------
2009-05-08 00:37:01 +08:00
- 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,
2009-04-30 09:00:33 +08:00
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'.
2009-04-17 04:21:28 +08:00
- 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.
2010-08-02 06:31:05 +08:00
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).

What's New in Python 3.1 alpha 2?
=================================
2009-04-05 05:06:52 +08:00
*Release date: 2009-4-4*
2009-03-08 02:46:21 +08:00
Core and Builtins
-----------------
2009-04-04 06:25:33 +08:00
- Implement PEP 378, Format Specifier for Thousands Separator, for
integers.
2009-03-08 02:46:21 +08:00
2009-04-04 06:22:42 +08:00
- 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.
2009-03-08 02:46:21 +08:00
Library
-------
2009-04-06 04:24:29 +08:00
- 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.
2009-04-01 12:28:33 +08:00
- Issue #5624: Fix the _winreg module name still used in several modules.
- Issue #5628: Fix io.TextIOWrapper.read() with a unreadable buffer.

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.
2009-03-31 11:25:07 +08:00
- 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.
2009-03-31 00:47:15 +08:00
- 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.
2009-03-29 21:02:52 +08:00
- 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.
2009-03-27 01:10:29 +08:00
- 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.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc.

2009-03-04 08:14:51 +08:00
- The io module has been reimplemented in C for speed.
2009-03-03 18:52:49 +08:00
- 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.
2009-02-08 23:00:52 +08:00
- 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.
2009-04-06 04:24:29 +08:00
- 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().

raised. Initial patch by Ezio Melotti.
- Issue #6516: Added owner/group support when creating tar archives in
Distutils.
- Issue #6954: Fixed crash when using DISTUTILS_DEBUG flag in Distutils.
- Issue #6163: Fixed HP-UX runtime library dir options in
distutils.unixcompiler. Initial patch by Sridhar Ratnakumar and
Michael Haubenwallner.
- Issue #6693: New functions in site.py to get user/global site packages paths.
- Issue #6511: ZipFile now raises BadZipfile (instead of an IOError) when
opening an empty or very small file.
- 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.

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.
