What's New in Python 2.7.1?
===========================
*Release date: XXXX-XX-XX*
Core and Builtins
-----------------
- Restore GIL in nis_cat in case of error.
- Issue #8530: Prevent stringlib fastsearch from reading beyond the front
of an array.
- Issue #83755: Implicit set-to-frozenset conversion was not thread-safe.
- Issue #9416: Fix some issues with complex formatting where the
output with no type specifier failed to match the str output:
- format(complex(-0.0, 2.0), '-') omitted the real part from the output,
- format(complex(0.0, 2.0), '-') included a sign and parentheses.
- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
compiler.
2010-07-03 11:51:25 -03:00
Library
-------
- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
are not held onto after they are deleted elsewhere.
- Issue #9626: the view methods for collections.OrderedDict() were returning
the unordered versions inherited from dict. Those methods are now
overridden to provide ordered views.
- Issue #8688: MANIFEST files created by distutils now include a magic
comment indicating they are generated. Manually maintained MANIFESTs
without this marker will not be overwritten or removed.
- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
and a BadZipfile error is raised if it doesn't match (as used to be the
case in Python 2.5 and earlier).
- Issue #9550: a BufferedReader could issue an additional read when the
original read request had been satisfied, which could block indefinitely
when the underlying raw IO channel was e.g. a socket. Report and original
patch by Jason V. Miller.
- Issue #9551: Don't raise TypeError when setting the value to None for
SafeConfigParser instances constructed with allow_no_value == True.
- Issue #6915: Under Windows, os.listdir() didn't release the Global
Interpreter Lock around all system calls. Original patch by Ryan Kelly.
- Issue #3757: thread-local objects now support cyclic garbage collection.
Thread-local objects involved in reference cycles will be deallocated
timely by the cyclic GC, even if the underlying thread is still running.
- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the
current node.
- Issue #6869: Fix a refcount problem in the _ctypes extension.
- Issue5504 - ctypes should now work with systems where mmap can't be
PROT_WRITE and PROT_EXEC.
- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
This is how it is supposed to work, wget and curl do the same. Previous
behavior was wrong.
- Issue #2944: asyncore doesn't handle connection refused correctly.
- Issue #3196: email header decoding is now forgiving if an RFC2047
encoded word encoded in base64 is lacking padding.
- Issue #9444: Argparse now uses the first element of prefix_chars as
the option character for the added 'h/help' option if prefix_chars
does not contain a '-', instead of raising an error.
- Issue #9354: Provide getsockopt() in asyncore's file_wrapper.
- Issue #7781: Fix restricting stats by entry counts in the pstats
interactive browser.
- Issue #9209: Do not crash in the pstats interactive browser on invalid
regular expressions.
- Issue #7372: Fix pstats regression when stripping paths from profile
data generated with the profile module.
- Issue #4108: In urllib.robotparser, if there are multiple 'User-agent: *'
entries, consider the first one.
- Issue #8397: Raise an error when attempting to mix iteration and regular
reads on a BZ2File object, rather than returning incorrect results.

2010-06-05 23:09:33 -03:00
What's New in Python 2.7 Release Candidate 1?
=============================================
2010-05-08 15:53:42 -03:00
2010-06-05 21:22:09 -03:00
*Release date: 2010-06-05*
2010-05-08 15:53:42 -03:00
Core and Builtins
-----------------
- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
start byte and the continuation byte(s) are now considered invalid, instead
of the number of bytes specified by the start byte.
E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
Previous versions returned a single u'\ufffd'.
- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
__hash__ in 3.x" warning. Also fix "XXX undetected error" that
arises from the "Overriding __eq__ blocks inheritance ..." warning
when turned into an exception: in this case the exception simply
gets ignored.
- Issue #8748: Fix two issues with comparisons between complex and integer
objects. (1) The comparison could incorrectly return True in some cases
(2**53+1 == complex(2**53) == 2**53), breaking transivity 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 #5211: Implicit coercion for the complex type is now completely
removed. (Coercion for arithmetic operations was already removed in 2.7
alpha 4, but coercion for rich comparisons was accidentally left in.)
- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
and error handler, instead of writing to the C stderr file in utf-8
- Issue #7902: When using explicit relative import syntax, don't try implicit
relative import semantics.
- Issue #7079: Fix a possible crash when closing a file object while using it
from another thread. Patch by Daniel Stutzbach.
- Issue #8868: Fix that ensures that python scripts have access to the
Window Server again in a framework build on MacOSX 10.5 or earlier.
C-API
-----
- Issue #5753: A new C API function, :cfunc:`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>`_.
2010-05-08 15:53:42 -03:00
Library
-------
2010-06-05 16:51:38 -03:00
- Issue #8302: SkipTest in unittest.TestCase.setUpClass or setUpModule is now
reported as a skip rather than an error.

unittest.TestCase.assertSequenceEqual are no longer included in failure
reports.
- Issue #8899: time.struct_time now has class and atribute docstrings.

mistake.
- Issue #1368247: set_charset (and therefore MIMEText) now automatically
encodes a unicode _payload to the output_charset.
- Issue #7150: Raise OverflowError if the result of adding or subtracting
timedelta from date or datetime falls outside of the MINYEAR:MAXYEAR range.
- Issue #6662: Fix parsing of malformatted charref (&#bad;), patch written by
Fredrik Håård
- Issue #8016: Add the CP858 codec.
- Issue #3924: Ignore cookies with invalid "version" field in cookielib.
- Issue #6268: Fix seek() method of codecs.open(), don't read or write the BOM
twice after seek(0). Fix also reset() method of codecs, UTF-16, UTF-32 and
StreamWriter classes.
- Issue #5640: Fix Shift-JIS incremental encoder for error handlers different
than 'strict'.
- Issue #8782: Add a trailing newline in linecache.updatecache to the last line
of files without one.
- Issue #8729: Return NotImplemented from ``collections.Mapping.__eq__()`` when
comparing to a non-mapping.
- Issue #8759: Fix user paths in sysconfig for posix and os2 schemes.
- Issue #1285086: Speed up ``urllib.quote()`` and urllib.unquote for simple
cases.
- Issue #8688: Distutils now recalculates MANIFEST everytime.
- Issue #5099: The ``__del__()`` method of ``subprocess.Popen`` (and the methods
it calls) referenced global objects, causing errors to pop up during
interpreter shutdown.
Extension Modules
-----------------
- Issue #7384: If the system readline library is linked against ncurses,
the curses module must be linked against ncurses as well. Otherwise it
is not safe to load both the readline and curses modules in an application.
- Issue #2810: Fix cases where the Windows registry API returns
ERROR_MORE_DATA, requiring a re-try in order to get the complete result.
- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
overflow checks in the ``audioop`` module.
2010-05-08 15:53:42 -03:00
Tests
-----
- Issue #8889: test_support.transient_internet rewritten so that the new
checks also work on FreeBSD, which lacks EAI_NODATA.
- Issue #8835: test_support.transient_internet() catches gaierror(EAI_NONAME)
and gaierror(EAI_NODATA)
- Issue #7449: Skip test_socketserver if threading support is disabled
- On darwin, ``test_site`` assumed that a framework build was being used,
leading to a failure where four directories were expected for site-packages
instead of two in a non-framework build.
Build
-----
- Display installer warning that Windows 2000 won't be supported in future
releases.
- Issues #1759169, #8864: Drop _XOPEN_SOURCE on Solaris, define it for

Core and Builtins
-----------------
- Run Clang 2.7's static analyzer for ``Objects/`` and ``Python/``.
- Issue #1533: Fix inconsistency in range function argument processing: any
non-float non-integer argument is now converted to an integer (if possible)
using its __int__ method. Previously, only small arguments were treated this
way; larger arguments (those whose __int__ was outside the range of a C long)
would produce a TypeError.
- Issue #8202: ``sys.argv[0]`` is now set to '-m' instead of '-c' when searching
for the module file to be executed with the -m command line option.
- Issue #7319: When -Q is used, do not silence DeprecationWarning.
- Issue #7332: Remove the 16KB stack-based buffer in
``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
benefit compared to the dynamic memory allocation fallback. Patch by
Charles-François Natali.
- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
passed to bytearray.
- Issue #7072: ``isspace(0xa0)`` is true on Mac OS X.

- Issue #8404: Fix set operations on dictionary views.
- 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``.
2010-04-10 15:53:58 -03:00
Library
-------
- Issue #8681: Make the zlib module's error messages more informative when the
zlib itself doesn't give any detailed explanation.
- Issue #8571: Fix an internal error when compressing or decompressing a chunk
larger than 1GB with the zlib module's compressor and decompressor objects.
- Issue #8573: asyncore ``_strerror()`` function might throw ValueError.
- 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.
2010-05-05 13:17:22 -03:00
- Issue #7755: Use an unencumbered audio file for tests.
- Issue #8621: ``uuid.uuid4()`` returned the same sequence of values in the
parent and any children created using ``os.fork`` on Mac OS X 10.6.
- Issue #8313: ``traceback.format_exception_only()`` encodes unicode message to
ASCII with backslashreplace error handler if ``str(value)`` failed.
- 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
exceptions raised by the implicit flush(). Also ensure that calling close()
several times is supported. Patch by Pascal Chambon.
- Issue #8576: logging updated to remove usage of find_unused_port().
- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
gc.DEBUG_STATS.
- 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")``.
- Issue #8577: ``distutils.sysconfig.get_python_inc()`` now makes a difference
between the build dir and the source dir when looking for "python.h" or
"Include".
- Issue #8464: tarfile no longer creates files with execute permissions set when
mode="w|" is used.
- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions of
the Linux kernel. Patch by Yaniv Aknin.
- Issue #6312: Fix http HEAD request when the transfer encoding is chunked. It
should correctly return an empty response now.
- 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. Based on initial patch by Lennart Regebro.
- Issue #8086: In :func:`ssl.DER_cert_to_PEM_cert()`, fix missing newline before
the certificate footer. Patch by Kyle VanderBeek.

- 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.
- Issue #5103: SSL handshake would ignore the socket timeout and block
indefinitely if the other end didn't respond.
- The do_handshake() method of SSL objects now adjusts the blocking mode of the
SSL structure if necessary (as other methods already do).
- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
- Issue #5238: Calling makefile() on an SSL object would prevent the underlying
socket from being closed until all objects get truely destroyed.

Initial patch by Péter Szabó.
- 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.
- 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 #8484: Load all ciphers and digest algorithms when initializing the _ssl
extension, such that verification of some SSL certificates doesn't fail

Tests
-----
- Issue #8672: Add a zlib test ensuring that an incomplete stream can be handled
by a decompressor object without errors (it returns incomplete uncompressed
data).

Build
-----
- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
(Optimization was unintentionally turned on in gcc --with-pydebug builds in
2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)
- Issue #8509: Fix quoting in help strings and code snippets in configure.in.
- Issue #3646: It is now easily possible to install a Python framework into your
home directory on Mac OS X, see Mac/README for more information.

What's New in Python 2.7 beta 1?
================================
2010-04-10 13:22:05 -03:00
*Release date: 2010-04-10*
2010-03-06 18:44:07 -04:00
Core and Builtins
-----------------
- Issue #7301: Add environment variable $PYTHONWARNINGS.
- Issue #8329: Don't return the same lists from select.select when no fds are
changed.
- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
2010-04-06 13:47:55 -03:00
on 64-bit machines. The shift count for either left or right shift is
permitted to be up to sys.maxsize.
- Ensure that tokenization of identifiers is not affected by locale.
- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
- Issue #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 #8268: Old-style classes (not just instances) now support weak
references.
- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
is set.
- Issue #1583863: An unicode subclass can now override the __unicode__ method
- Issue #6474: Make error message from passing an inadequate number of keyword
arguments to a function correct.
- Issue #8164: Don't allow lambda functions to have a docstring.
- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
(SIGINT). If an error occurs while importing the site module, the error is
printed and Python exits. Initialize the GIL before importing the site
module.
- Code objects now support weak references.
2010-03-06 18:44:07 -04:00
Library
-------
- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
`ssl.OPENSSL_VERSION_NUMBER`.
2010-04-04 20:23:22 -03:00
- Issue #8310: Allow dis to examine new style classes.
- Issue #8257: The Decimal construct now accepts a float instance directly,
converting that float to a Decimal of equal value:
2010-04-03 12:47:46 -03:00
>>> Decimal(1.1)
Decimal('1.100000000000000088817841970012523233890533447265625')
- collections.Counter() now supports a subtract() method.
- The functools module now has a total_ordering() class decorator to simplify
the specification of rich comparisons.
2010-04-04 15:34:45 -03:00
- The functools module also adds cmp_to_key() as a tool to transition old-style
comparison functions to new-style key-functions.
2010-04-04 15:34:45 -03:00
- Issue #8294: The Fraction constructor now accepts Decimal and float instances
directly.
- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
InvalidOperation instead of returning False. (Comparisons involving a quiet
NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
signaling NaNs remain unhashable.
- Issue #2531: Comparison operations between floats and Decimal instances now
return a result based on the numeric values of the operands; previously they
returned an arbitrary result based on the relative ordering of id(float) and
id(Decimal).
- Issue #8233: When run as a script, py_compile.py optionally takes a single
argument `-` which tells it to read files to compile from stdin. Each line is
read on demand and the named file is compiled immediately. (Original patch by
Piotr Ożarowski).
- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
function like a normal call.
- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
form feed (0x0C) are now considered linebreaks, as specified in Unicode
Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
- Comparisons using one of <, <=, >, >= between a complex instance and a
Fractions instance now raise TypeError instead of returning True/False. This
makes Fraction <=> complex comparisons consistent with int <=> complex, float
<=> complex, and complex <=> complex comparisons.
2010-03-27 08:14:37 -03:00
- Addition of ``WeakSet`` to the ``weakref`` module.
- logging: Added LOG_FTP to SysLogHandler and updated documentation.
- Issue #8205: Remove the "Modules" directory from sys.path when Python is
running from the build directory (POSIX only).
- Issue #7667: Fix doctest failures with non-ASCII paths.
- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
didn't support chflags() (for example ZFS under FreeBSD). The error is now
silenced.
- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
deprecated.
- Issue #7860: platform.uname now reports the correct 'machine' type when Python
is running in WOW64 mode on 64 bit Windows.
- logging: Added getChild utility method to Logger and added isEnabledFor method
to LoggerAdapter.
- Issue #8201: logging: Handle situation of non-ASCII and Unicode logger names
existing at the same time, causing a Unicode error when configuration code
attempted to sort the existing loggers.
- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
when logging occurs.
- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
reads and writes are always retried by OpenSSL itself.
- Issue #8179: Fix macpath.realpath() on a non-existing path.
- Issue #8024: Update the Unicode database to 5.2.
- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support writing
into objects supporting the new buffer API, for example bytearrays or
memoryviews.
- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
with Tcl/Tk-8.5.
- Issue #8140: Extend compileall to compile single files. Add -i option.
- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of the
locale.
- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set
to an non existent program name and Python is unable to retrieve the real
program name.
- Issue #8117: logging: Improved algorithm for computing initial rollover time
for ``TimedRotatingFileHandler`` by using the modification time of an existing
log file to compute the next rollover time. If the log file does not exist,
the current time is used as the basis for the computation.
- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The
cElementTree module is updated too.
- Issue #7880: Fix sysconfig when the python executable is a symbolic link.
- Issue #7624: Fix ``isinstance(foo(), collections.Callable)`` for old-style
classes.
- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
a base64 transfer-encoded payload *after* decoding it; it no longer does.
This is a behavior change, so email's minor version number is now bumped, to
version 4.0.2, for the 2.7 release.
- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is
a socket option available on FreeBSD 7.1 and newer.
- Issue #8038: unittest.TestCase.assertNotRegexpMatches
- Addition of -b command line option to unittest for buffering stdout / stderr
during test runs.
2010-05-15 18:00:59 -03:00
- Issue #1220212: Added os.kill support for Windows, including support for
sending CTRL+C and CTRL+BREAK events to console subprocesses.

2010-03-14 21:02:36 -03:00
- Issue #8142: Update libffi to the 3.0.9 release.
- 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 #1530559: When passing a non-integer argument to struct.pack with *any*
integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
argument's __int__ method to convert to an integer before packing. It also
produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
inconsistent: __int__ was used for some integer codes but not for others, and
the set of integer codes for which it was used differed between native packing
and standard packing.)
- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a bug in
the return value of QueryReflectionKey.
2010-04-02 18:51:37 -03:00
Tools/Demos
-----------
- Issue #7993: Add a test of IO packet processing bandwidth to ccbench. It
measures the number of UDP packets processed per second depending on the
number of background CPU-bound Python threads.
2010-03-06 18:44:07 -04:00
- python-config now supports multiple options on the same command line.
2010-03-14 11:24:31 -03:00
Build
-----
- Issue #8032: For gdb7, a python-gdb.py file is added to the build, allowing to
use advanced gdb features when debugging Python.
- Issue #1628484: The Makefile doesn't ignore the CFLAGS environment variable
anymore. It also forwards the LDFLAGS settings to the linker when building a
shared library.
- Issue #6716: Quote -x arguments of compileall in MSI installer.
2010-03-14 11:24:31 -03:00
- Issue #7705: Fix linking on FreeBSD.
2010-04-07 13:34:08 -03:00
- Make sure that the FreeBSD build of the included libffi uses the proper
assembly file.
C-API
-----
- Issue #8276: PyEval_CallObject() is now only available in macro form. The
function declaration, which was kept for backwards compatibility reasons, is
now removed (the macro was introduced in 1997!).
- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported from
Python 3.1. All existing Python CObjects in the main distribution have been
converted to capsules. To address backwards-compatibility concerns,
PyCObject_AsVoidPtr() was changed to understand capsules.
Tests
-----
- 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 #8348: Fix test ftp url in test_urllib2net.
- Issue #8204: Fix test_ttk notebook test by forcing focus.
- Issue #8344: Fix test_ttk bug on FreeBSD.
- 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).
2010-03-25 17:33:49 -03:00
- Issue #8180 and #8207: Fix test_pep277 on OS X and add more tests for special
Unicode normalization cases.
- Issue #7783: test.test_support.open_urlresource invalidates the outdated files
from the local cache.

bugs and allows loading SQLite extensions from shared libraries.
- Issue #7808: Fix reference leaks in _bsddb and related tests.
- Issue #6544: Fix a reference leak in the kqueue implementation's error
handling.
- Stop providing crtassem.h symbols when compiling with Visual Studio 2010, as
msvcr100.dll is not a platform assembly anymore.
2010-02-06 14:26:27 -04:00
- Issue #7242: On Solaris 9 and earlier calling ``os.fork()`` from within a

is run with the -OO flag. Tests requiring docstrings are skipped.
- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
now also used by regrtest to run all the tests in a temporary directory. The
original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
Xicluna who helped with the patch.
Build
-----
- Issue #3920, #7903: Define _BSD_SOURCE on OpenBSD 4.4 through 4.9.

*Release date: 2010-02-06*
2010-01-09 13:30:31 -04:00
Core and Builtins
-----------------
- Issue #5677: Explicitly forbid write operations on read-only file objects,
and read operations on write-only file objects. On Windows, the system C
library would return a bogus result; on Solaris, it was possible to crash the
interpreter. Patch by Stefan Krah.
- Issue #7853: Normalize exceptions before they are passed to a context
manager's ``__exit__()`` method.
- Issue #7385: Fix a crash in ``PyMemoryView_FromObject()`` when
``PyObject_GetBuffer()`` fails. Patch by Florent Xicluna.
- Issue #7819: Check ``sys.call_tracing()`` arguments types.
- Issue #7788: Fix an interpreter crash produced by deleting a list slice with
very large step value.
- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
and add the additional members returned in an OSVERSIONINFOEX structure. The
new members are service_pack_major, service_pack_minor, suite_mask, and
product_type.
- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
returning NULL. The macro now returns a statically allocated empty string
instead.
- Issue #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.
- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
option is not used.
- Issue #2335: Backport set literals syntax from Python 3.x.
2010-01-11 19:13:49 -04:00
- Issue #2333: Backport set and dict comprehensions syntax from Python 3.x.
- Issue #1967: Backport dictionary views from Python 3.x.
2010-01-09 13:30:31 -04:00
Library
-------
- Issue #9137: Fix issue in MutableMapping.update, which incorrectly
treated keyword arguments called 'self' or 'other' specially.
- Issue #7835: shelve should no longer produce mysterious warnings during
interpreter shutdown.
- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
XML processing instructions and comments. These raw characters are allowed
by the XML specification, and are necessary when outputting e.g. PHP code in
a processing instruction. Patch by Neil Muller.
- Issue #7869: logging: Improved diagnostic for format-time errors.
- Issue #7868: logging: Added loggerClass attribute to Manager.
- Issue #7851: logging: Clarification on logging configuration files.
- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Also, raise ValueError rather than TypeError when an unknown TIPC address
type is specified. Patch by Brian Curtin.
2010-02-04 14:48:53 -04:00
- logging: Implemented PEP 391.
- 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 ``zipfile.ZipExtFile``
class used to represent files stored inside an archive. The new
implementation is significantly faster and can be wrapped in a
``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 #7792: Registering non-classes to ABCs raised an obscure error.
- Removed the deprecated functions ``verify()`` and ``vereq()`` from
Lib/test/test_support.py.
- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
when the release file is empty.
- Issue #7748: Since unicode values are supported for some metadata options in
Distutils, the DistributionMetadata get_* methods will now return an utf-8
encoded string for them. This ensures that the upload and register commands
send the correct values to PyPI without any error.
- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
headers in multipart/signed MIME parts, which fixes one of the sources of
invalid modifications to such parts by Generator.
- Issue #7701: Fix crash in ``binascii.b2a_uu()`` in debug mode when given a
1-byte argument. Patch by Victor Stinner.
- Issue #3299: Fix possible crash in the _sre module when given bad argument
values in debug mode. Patch by Victor Stinner.
- Issue #7703: Add support for the new buffer API to functions of the binascii
module. Backported from py3k by Florent Xicluna, with some additional tests.
- Issue #2846: Add support for gzip.GzipFile reading zero-padded files. Patch
by Brian Curtin.
- Issue #5827: Make sure that normpath preserves unicode. Initial patch by
Matt Giuca.
- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since
Extension extra options may change the output without changing the .c file).
Initial patch by Collin Winter.
Extension Modules
-----------------
- Expat: Fix DoS via XML document with malformed UTF-8 sequences
(CVE_2009_3560).
Build
-----
- Issue #7632: When Py_USING_MEMORY_DEBUGGER is defined, disable the private
memory allocation scheme in dtoa.c and use PyMem_Malloc and PyMem_Free
instead. Also disable caching of powers of 5.
- Issue #7658: Ensure that the new pythonw executable works on OSX 10.4
- Issue #7714: Use ``gcc -dumpversion`` to detect the version of GCC on
MacOSX.
- Issue #7661: Allow ctypes to be built from a non-ASCII directory path.
Patch by Florent Xicluna.
Tools/Demos
-----------
- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were
added to the ``Tools`` directory. They were previously living in the
sandbox.
Tests
-----
- issue #7728: test_timeout was changed to use ``test_support.bind_port()``
instead of a hard coded port.
Documentation
-------------
- Updated "Using Python" documentation to include description of CPython's -J,
-U and -X options.
- Updated Python manual page (options -B, -O0, -s, environment variables
PYTHONDONTWRITEBYTECODE, PYTHONNOUSERSITE).

*Release date: 2010-01-09*
2009-12-05 14:40:02 -04:00
Core and Builtins
-----------------
- 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 #5080: A number of functions and methods previously produced a
DeprecationWarning when passed a float argument where an integer was expected.
These functions and methods now raise TypeError instead. The majority of the
effects of this change are in the extension modules, but some core functions
and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
and many unicode/str methods.
- Issue #7604: Deleting an unset slotted attribute did not raise an
AttributeError.
- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
in ** operator. The behaviour now conforms to that described in C99 Annex F.
- Issue #7579: The msvcrt module now has docstrings for all its functions.
- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
used to drop the time part of the result.
- 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 a long.
- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
in the subclass.
- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
executables on OSX.
These executables now work properly with the arch(1) command: ``arch -ppc
python`` will start a universal binary version of python in PPC mode (unlike
previous releases).
- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
underlying error when the coercion fails for the left hand operand.
- Issue #7491: Metaclass's __cmp__ method was ignored.
- Issue #7466: Segmentation fault when the garbage collector is called in the
middle of populating a tuple. Patch by Florent Xicluna.
2009-12-05 14:40:02 -04:00
Library
-------
- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
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.
- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc
when it has a fully qualified configuration prefix. Initial patch by
Arfrever.
- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
renaming of `cPickle` to `pickle`. The warning was annoying since there's no
alternative to cPickle if you care about performance. Patch by Florent
Xicluna.
- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by Victor
Stinner.
- Issue #7092: Fix the DeprecationWarnings emitted by the standard library when
using the -3 flag. Patch by Florent Xicluna.
- Issue #7471: Improve the performance of GzipFile's buffering mechanism, and
make it implement the ``io.BufferedIOBase`` ABC to allow for further speedups
by wrapping it in an ``io.BufferedReader``. Patch by Nir Aides.
- Issue #3972: ``httplib.HTTPConnection`` now accepts an optional source_address
parameter to allow specifying where your connections come from.
- ``socket.create_connection()`` now accepts an optional source_address
parameter.
- Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager.
Initial patch by Brian Curtin.
- Distutils now correctly identifies the build architecture as "x86_64" when
building on OSX 10.6 without "-arch" flags.
- Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest file in text
mode.
2009-12-21 19:37:44 -04:00
- 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
long passwords. Initial patch by JP St. Pierre.
- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by
Tatsuhiro Tsujikawa.
- Issue #7349: Make methods of file objects in the io module accept None as an
argument where file-like objects (ie StringIO and BytesIO) accept them to mean
the same as passing no argument.
- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
argument like other file objects.
2009-12-13 13:31:31 -04:00
- Issue #7357: tarfile no longer suppresses fatal extraction errors by default.
- Issue #7470: logging: Fix bug in Unicode encoding fallback.
- Issue #5949: Fixed IMAP4_SSL hang when the IMAP server response is missing
proper end-of-line termination.
- Issue #7457: Added a read_pkg_file method to
``distutils.dist.DistributionMetadata``.
2009-12-05 14:40:02 -04:00
- Issue #3745: Undo the 2.7a1 change to have hashlib to reject unicode and non
buffer API supporting objects as input. That behavior is for 3.x only.
2010-01-02 18:42:50 -04:00
C-API
-----
- Issue #7767: New function ``PyLong_AsLongLongAndOverflow()`` added, analogous
to ``PyLong_AsLongAndOverflow()``.
- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
float arguments for integer format codes (other than 'L'): previously an
attempt to pass a float resulted in a DeprecationWarning; now it gives a
TypeError. For the 'L' format code (which previously had no warning) there is
now a DeprecationWarning.
- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.
2009-12-21 15:29:59 -04:00
Build
-----
- Issue #6491: Allow --with-dbmliborder to specify that no dbms will be built.
2010-01-01 11:18:38 -04:00
- Issue #6943: Use pkg-config to find the libffi headers when the
``--with-system-ffi`` flag is used.
2010-01-01 11:18:38 -04:00
- Issue #7609: Add a ``--with-system-expat`` option that causes the system's
expat library to be used for the pyexpat module instead of the one included
with Python.
- Issue #7589: Only build the nis module when the correct header files are
found.
2010-01-02 05:25:21 -04:00
- Switch to OpenSSL 0.9.8l and sqlite 3.6.21 on Windows.
- Issue #7541: when using ``python-config`` with a framework install the
compiler might use the wrong library.
Tests
-----
- Issue #7376: Instead of running a self-test (which was failing) when called
with no arguments, doctest.py now gives a usage message.
- Issue #7396: Fix regrtest -s, which was broken by the -j enhancement.
- Issue #7498: test_multiprocessing now uses test_support.find_unused_port
instead of a hardcoded port number in test_rapid_restart.

Core and Builtins
-----------------
- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
when called with invalid values.
- Issue #3382: 'F' formatting for float and complex now convert the result to
upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
to 'g' for large values.
- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1e50 in absolute value.
- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1e-100 used to raise OverflowError, but now gives the requested 120
significant digits instead.
- Add Py3k warnings for parameter names in parentheses.
- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
10.6.
- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
decimal string that's guaranteed to round back to x under correct rounding
(with round-half-to-even rounding mode). Previously it gave a string based on
rounding x to 17 decimal digits. repr(x) for a complex number behaves
similarly. On platforms where the correctly-rounded strtod and dtoa code is
not supported (see below), repr is unchanged.
- Issue #7117: On almost all platforms: float-to-string and string-to-float
conversions within Python are now correctly rounded. Places these conversions
occur include: str for floats and complex numbers; the float and complex
constructors; old-style and new-style numeric formatting; serialization and
deserialization of floats and complex numbers using marshal, pickle and json;
parsing of float and imaginary literals in Python code; Decimal-to-float
conversion.
The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
providing correctly-rounded strtod and dtoa C functions. This code is
supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
the C compiler. There may be a small number of platforms on which correct
operation of this code cannot be guaranteed, so the code is not used: notably,
this applies to platforms where the C double format is not IEEE 754 binary64,
and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
and Python's configure script is unable to determine how to change the FPU
precision. On these platforms conversions use the platform strtod and dtoa,
as before.
- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
uses the correctly-rounded string <-> float conversions described above (when
available), and so produces correctly rounded results that will display nicely
under the float repr. There are two related small changes: (1) round now
accepts any class with an ``__index__()`` method for its second argument (but
no longer accepts floats for the second argument), and (2) an excessively
large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
raises an exception.
- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
- Fix several issues with ``compile()``. The input can now contain Windows and
Mac newlines and is no longer required to end in a newline.
- Remove length limitation when constructing a complex number from a unicode
string.
- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
during the formation of an output tuple.
- Issue #1087418: Boost performance of bitwise operations for longs.
- 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 #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``,
and note that they are unsafe and deprecated.
- Issue #7120: logging: Remove import of multiprocessing which is causing crash
in GAE.
- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
module is the only object holding a reference to it.
- Issue #1754094: Improve the stack depth calculation in the compiler. There
should be no other effect than a small decrease in memory use. Patch by
Christopher Tur Lesniewski-Laas.
- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
and mutating it from another one. Patch by Scott Dial.
- Issue #1571184: The Unicode database contains properties for more characters.
The tables for code points representing numeric values, white spaces or line
breaks are now generated from the official Unicode Character Database files,
and include information from the Unihan.txt file.
- Issue #7050: Fix a SystemError when trying to use unpacking and augmented
assignment.
- Issue #5329: Fix ``os.popen*`` regression from 2.5 with commands as a sequence
running through the shell. Patch by Jean-Paul Calderone and Jani Hakala.
- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of
producing internally inconsistent Python longs.
- Issue #6990: Fix ``threading.local`` subclasses leaving old state around after
a reference cycle GC which could be recycled by new locals.
2009-09-18 18:47:27 -03:00
- Issue #6300: unicode.encode, unicode.decode, str.decode, and str.encode now
take keyword arguments.
- Issue #6922: Fix an infinite loop when trying to decode an invalid UTF-32
stream with a non-raising error handler like "replace" or "ignore".
- Issue #6713: Improve performance of base 10 int -> string and long -> string
conversions.
2009-09-16 17:36:34 -03:00
- Issue #1590864: Fix potential deadlock when mixing threads and fork().
- Issue #6844: Do not emit DeprecationWarnings when accessing a "message"
attribute on exceptions that was set explicitly.
- Issue #6846: Fix bug where bytearray.pop() returns negative integers.
- ``classmethod()`` no longer checks if its argument is callable.
- Issue #6750: A text file opened with ``io.open()`` could duplicate its output
when writing from multiple threads at the same time.
- Issue #6704: Improve the col_offset in AST for "for" statements with a target
of tuple unpacking.
- Issue #6707: ``dir()`` on an uninitialized module caused a crash.
- Issue #6540: Fixed crash for ``bytearray.translate()`` with invalid parameters.
- Issue #6573: ``set.union()`` stopped processing inputs if an instance of self
occurred in the argument chain.
2009-07-13 17:03:21 -03:00
- Issue #1616979: Added the cp720 (Arabic DOS) encoding.
- Issue #6070: On posix platforms import no longer copies the execute bit from
the .py file to the .pyc file if it is set. Patch by Marco N.
- Issue #4618: When unicode arguments are passed to ``print()``, the default
separator and end should be unicode also.
2010-03-07 11:23:59 -04:00
- Issue #6119: Fixed an incorrect Py3k warning about order comparisons of
built-in functions and methods.
- 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.
2009-06-28 07:23:00 -03:00
- Issue #4856: Remove checks for win NT.
- Issue #2016: Fixed a crash in a corner case where the dictionary of keyword
arguments could be modified during the function call setup.
- Removed the ipaddr module.
- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
because it wasn't recognized as a sequence).
- Issue #6289: Encoding errors from ``compile()`` were being masked.
- When no module is given in a relative import, the module field of the
ImportFrom AST node is now None instead of an empty string.
- Assignment to None using import statements now raises a SyntaxError.
- Issue #4547: When debugging a very large function, it was not always possible
to update the lineno attribute of the current frame.
- Issue #5330: C functions called with keyword arguments were not reported by
the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
- 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 #6101: A new opcode, SETUP_WITH, has been added to speed up the with
statement and correctly lookup the __enter__ and __exit__ special methods.
- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
consistent with float("1e500") and interpretation of real and imaginary
literals.
2009-05-16 23:58:36 -03:00
- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
- ``__instancecheck__()`` and ``__subclasscheck__()`` are now completely ignored
on classic classes and instances.
2009-05-16 19:46:11 -03:00
- 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').
- 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.
- 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 #1588: Add complex.__format__. For example, ``format(complex(1, 2./3),
'.5')`` now produces a sensible result.
2009-04-29 21:58:58 -03:00
- 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 #4971: Fix titlecase for characters that are their own titlecase, but
not their own uppercase.
- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
_PyOS_double_to_string or PyOS_double_to_string.
- 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.
- Implement PEP 378, Format Specifier for Thousands Separator, for floats, ints,
and longs.
- Issue #5515: 'n' formatting for ints, longs, and floats handles leading zero
formatting poorly.
- Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no
type code and we have an exponent.
- Issue #3166: Make long -> float (and int -> float) conversions correctly
rounded.
- Issue #5787: ``object.__getattribute__(some_type, "__bases__")`` segfaulted on
2010-03-07 11:23:59 -04:00
some built-in types.
- Issue #1869: Fix a couple of minor round() issues. ``round(5e15+1)`` was
giving 5e15+2; ``round(-0.0)`` was losing the sign of the zero.
- Issue #5759: float() didn't call __float__ on str subclasses.
- Issue #5704: The "-3" command-line option now implies "-t".
2009-04-12 09:08:12 -03:00
- Issue #2170: Refactored ``xml.dom.minidom.normalize``, increasing both its
clarity and its speed.
- Issue #2396: The memoryview object was backported from Python 3.1.
- 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.
- 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.long_info structseq to
provide information about the internal format.
- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
result traceback.__members__ no longer exists.)
- 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 #3652: Make the 'line' argument for ``warnings.showwarning()`` a
requirement. Means the DeprecationWarning from Python 2.6 can go away.
- Issue #5247: Improve error message when unknown format codes are used when
using ``str.format()`` with str, unicode, long, int, and float arguments.
- Running Python with the -3 option now also warns about classic division for
ints and longs.
- Issue #5260: Long integers now consume less memory: average saving is 2 bytes
per long on a 32-bit system and 6 bytes per long on a 64-bit system.
- 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 #4978: Passing keyword arguments as unicode strings is now allowed.
2009-04-05 17:23:13 -03:00
- Issue #1242657: the __len__() and __length_hint__() calls in several tools
were suppressing all exceptions. These include list(), filter(), map(),
zip(), and bytearray().
2009-01-19 11:42:23 -04:00
- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
functions.
2009-01-18 20:08:08 -04:00
- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
OSError.
- Issue #4807: Port the _winreg module to Windows CE.
- 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.
2009-01-12 04:11:24 -04:00
- Issue #4893: Use NT threading on CE.
- Issue #4915: Port sysmodule to Windows CE.
- 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
2009-07-12 21:03:20 -03:00
Martin von Löwis at
http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
- 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 #4075: Use ``OutputDebugStringW()`` in Py_FatalError.
- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
file with `str' 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 #4764: With io.open, IOError.filename is set when trying to open a
directory on POSIX systems.
- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
systems.
- 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 #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 and long.
- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
patch by Neal Norwitz.
- Issue #4597: Fixed exception handling when the __exit__ function of a context
manager returns a value that cannot be converted to a bool.
- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
2008-12-10 03:35:02 -04:00
- Issue #4445: Replace ``sizeof(PyStringObject)`` with
``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
instances. On a typical machine this saves 3 bytes of memory (on average) per
string allocation.
- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
interpreter to abort ("Fatal Python error: Could not reset the stack!")
instead of throwing a MemoryError.
- Issue #3689: The list reversed iterator now supports __length_hint__ instead
of __len__. Behavior now matches other reversed iterators.
2008-12-03 11:42:10 -04:00
- Issue #4367: Python would segfault during compiling when the unicodedata
module couldn't be imported and \N escapes were present.
- 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 #4348: Some bytearray methods returned that didn't cause any change to
the bytearray, returned the same bytearray instead of a copy.
- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
- Issue #4048: The parser module now correctly validates relative imports.
- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
exec statement.
- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
does not return iterators for the 4th and 5th items.
- Issue #4209: Enabling unicode_literals and the print_function in the same
__future__ import didn't work.
- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
2008-10-25 04:00:52 -03:00
because it is a reserved word in 3.x.
- On windows, ``os.chdir()`` given unicode was not working if
GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
this code path is really executed because I cannot move to such directory on
win2k)
- Issue #4069: When ``set.remove(element)`` is used with a set element, the
element is temporarily replaced with an equivalent frozenset. But the
eventual KeyError would always report the empty ``frozenset()`` as the missing
key. Now it correctly refers to the initial element.
- Issue #4509: Various issues surrounding resize of bytearray objects to which
there are buffer exports.
- Issue #4748: Lambda generators no longer return a value.
2009-01-12 05:20:34 -04:00
- Issue #3582: Use native TLS functions on Windows
- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
file names.
- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
to avoid compiler warnings.
2009-04-05 20:48:26 -03:00
- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
returned them on 64bit platforms.
- Issue #5108: Handle %s like %S and %R 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().
2009-05-06 11:32:35 -03:00
- Issue #3739: The unicode-internal encoder now reports the number of characters
consumed like any other encoder (instead of the number of bytes).
- 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.
2008-10-02 00:33:51 -03:00

or SSL. Patch by Giampaolo Rodola'.
- Issue #4969: The mimetypes module now reads the MIME database from the
registry under Windows. Patch by Gabriel Genellina.
- Issue #6816: runpy now provides a run_path function that allows Python code to
execute file paths that refer to source or compiled Python files as well as
zipfiles, directories and other valid sys.path entries that contain a
__main__.py file. This allows applications that run other Python scripts to
support the same flexibility as the CPython command line itself.
- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
connection with another process, rather than looping endlessly. The default
timeout is 20 seconds, which should be amply sufficient for local connections.

a modification is done through it. This fixes inconsistencies and test
failures on systems with slightly bogus mtime behaviour.
- Issue #7246 & Issue #7208: getpass now properly flushes input before reading
from stdin so that existing input does not confuse it and lead to incorrect

symlink to "Program Files" on Vista.
- Issue #4710: Extract directories properly in the zipfile module; allow adding
directories to a zipfile.

--without-threads argument. When this occurs, _multiprocessing will be
disabled, and not compiled.
- Issue #5008: When a file is opened in append mode with the new IO library, do
an explicit seek to the end of file (so that e.g. tell() returns the file size
rather than 0). This is consistent with the behaviour of the traditional 2.x
file object.
- Issue #5013: Fixed a bug in FileHandler which occurred when the delay
parameter was set.
- Issue #4998: The memory saving effect of __slots__ had been lost on Fractions
which inherited from numbers.py which did not have __slots__ defined. The
2009-02-12 13:55:42 -04:00
numbers hierarchy now has its own __slots__ declarations.
- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks
for *nix machines for negative handles and large int handles. Without this
check it is possible to segfault the interpreter.
- Issue #4449: AssertionError in mp_benchmarks.py, caused by an underlying issue
in sharedctypes.py.
- Issue #1225107: inspect.isclass() returned True for instances with a custom
__getattr__.
- Issue #3997: Zipfiles generated with more than 65536 files could not be opened
with other applications.
- Issue #1162154: ``inspect.getmembers()`` now skips attributes that raise
AttributeError, e.g. a __slots__ attribute which has not been set.

2009-01-10 12:15:24 -04:00
- Issue #3860: GzipFile and BZ2File now support the context manager protocol.
- Issue #4272: Add an optional argument to the GzipFile constructor to override
the timestamp in the gzip stream. The default value remains the current time.
The information can be used by e.g. gunzip when decompressing. Patch by
Jacques Frechet.
2009-01-04 17:25:40 -04:00

- Issue #3248: Allow placing ScrolledText in a PanedWindow.
- Issue #4444: Allow assertRaises() to be used as a context handler, so that the
code under test can be written inline if more practical.
- Issue #4739: Add pydoc help topics for symbols, so that e.g. help('@') works
as expected in the interactive environment.

- Issue #3954: Fix a potential SystemError in _hotshot.logreader error handling.
- Issue #4574: Fix a crash in io.IncrementalNewlineDecoder when a carriage
return encodes to more than one byte in the source encoding (e.g. UTF-16) and
gets split on a chunk boundary.
- Issue #4223: inspect.getsource() will now correctly display source code for
packages loaded via zipimport (or any other conformant PEP 302
loader). Original patch by Alexander Belopolsky.
- Issue #4201: pdb can now access and display source code loaded via zipimport
(or any other conformant PEP 302 loader). Original patch by Alexander
Belopolsky.
- Issue #4197: Doctests in modules loaded via zipimport (or any other PEP 302
conformant loader) will now work correctly in most cases (they are still
subject to the constraints that exist for all code running from inside a
module loaded via a PEP 302 loader and attempting to perform IO operations
based on __file__). Original patch by Alexander Belopolsky.
- Issues #4082 and #4512: Add runpy support to zipimport in a manner that allows
backporting to maintenance branches. Original patch by Alexander Belopolsky.
- Issue #4163: Use unicode-friendly word splitting in the textwrap functions
when given an unicode string.
- Issue #4616: TarFile.utime(): Restore directory times on Windows.

support unusual filenames (such as those containing semi-colons) in
Content-Disposition headers.
- Issue #4384: Added logging integration with warnings module using
captureWarnings(). This change includes a NullHandler which does nothing; it
will be of use to library developers who want to avoid the "No handlers could

configure logging.
- Issue #3741: DISTUTILS_USE_SDK set causes msvc9compiler.py to raise an
exception.
- Issue #4363: The uuid.uuid1() and uuid.uuid4() functions now work even if the
ctypes module is not present.
- FileIO's mode attribute now always includes ``"b"``.

biarch systems. Try to rely on ldconfig only, without using objdump and gcc.
- Issue #5104: The socket module now raises OverflowError when 16-bit port and
protocol numbers are supplied outside the allowed 0-65536 range on bind() and
getservbyport().

2009-01-28 11:56:01 -04:00
- Issue #4677: Add two list comprehension tests to pybench.
Build
-----
- Issue #6603: Change READ_TIMESTAMP macro in ceval.c so that it compiles
correctly under gcc on x86-64. This fixes a reported problem with the
--with-tsc build on x86-64.
- Add 2 new options to ``--with-universal-archs`` on MacOSX: ``intel`` builds a
distribution with ``i386`` and ``x86_64`` architectures, while ``3-way``
builds a distribution with the ``ppc``, ``i386`` and ``x86_64`` architectures.
- Issue #6802: Fix build issues on MacOSX 10.6.
2009-08-16 11:38:57 -03:00

C-API
-----
- Issue #7528: Add PyLong_AsLongAndOverflow (backported from py3k).
- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V) and
PyErr_Format, on machines with HAVE_LONG_LONG defined.
- Add new C-API function PyOS_string_to_double, and deprecated PyOS_ascii_atof
and PyOS_ascii_strtod.
- Removed _PyOS_double_to_string. Use PyOS_double_to_string instead. This is in
preparation for (but not strictly related to) issue #7117, short float repr.
- Issue #6624: PyArg_ParseTuple with "s" format when parsing argument with NULL:
Bogus TypeError detail string.
- 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.
- Some PyBytes_* aliases have been removed because they don't exist in 3.x.
- Issue #5175: PyLong_AsUnsignedLongLong now raises OverflowError for negative
arguments. Previously, it raised TypeError.
2008-12-22 16:52:53 -04:00
- Issue #4720: The format for PyArg_ParseTupleAndKeywords can begin with '|'.
- Issue #3632: From the gdb debugger, the 'pyo' macro can now be called when the

asynchronous notifications to python from any thread. Documentation added.
Extension Modules
-----------------
- Issue #6508: Add posix.{getresuid,getresgid,setresuid,setresgid}.
- Issue #7078: Set struct.__doc__ from _struct.__doc__.
- Issue #3366: Add erf, erfc, expm1, gamma, lgamma functions to math module.
- Issue #6823: Allow time.strftime() to accept a tuple with a isdst field
outside of the range of [-1, 1] by normalizing the value to within that range.
- Issue #6877: Make it possible to link the readline extension to libedit on
OSX.
- Issue #6944: Fix a SystemError when socket.getnameinfo() was called with
something other than a tuple as first argument.
- Issue #6865: Fix reference counting issue in the initialization of the pwd
module.
- Issue #6848: Fix curses module build failure on OS X 10.6.
- Fix a segfault in expat when given a specially crafted input lead to the
tokenizer not stopping. CVE-2009-3720.
- Issue #6561: '\d' in a regex now matches only characters with Unicode category
'Nd' (Number, Decimal Digit). Previously it also matched characters with
category 'No'.
- Issue #1523: Remove deprecated overflow wrapping for struct.pack with an
integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
consistently raises struct.error.
- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the
integer formats ('bBhHiIlLqQ'). In the following, '*' represents any of '=',
'<', '>'.
- Packing a float now always gives a Deprecation Warning. Previously it
only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
- If x is not an int, long or float, then packing x will always result in
struct.error. Previously an x with an __int__ method could be packed by
'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
__long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
neither __int__ nor __long__, TypeError used to be raised (with a
confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
struct.error in other cases.
Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
argument with an __int__ method can be packed, but use of this feature
triggers a DeprecationWarning.
- Issue #4873: Fix resource leaks in error cases of pwd and grp.
- Issue #4751: For hashlib algorithms provided by OpenSSL, the Python GIL is now
released during computation on data lengths >= 2048 bytes.
- Issue #3745: Fix hashlib to always reject unicode and non buffer-api
supporting objects as input no matter how it was compiled (built in
2010-01-02 18:42:50 -04:00
implementations or external openssl library). NOTE: Undone in 2.7a2.
2009-01-15 11:17:43 -04:00
- Issue #4397: Fix occasional test_socket failure on OS X.
- Issue #4279: Fix build of parsermodule under Cygwin.
- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.
- Issue #1040026: Fix os.times result on systems where HZ is incorrect.
- Issues #3167, #3682: Fix test_math failures for log, log10 on Solaris,
OpenBSD.
- Issue #4365: Add crtassem.h constants to the msvcrt module.
- Issue #4396: The parser module now correctly validates the with statement.
- Issue #5228: Make functools.partial objects can now be pickled.
Tests
-----
- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
in the Lib/test directory, which might be read-only for the user running the
tests.
- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
of an option with no handler.
- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
fails. Can be combined with -j.
- Issue #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 #7222: Make thread "reaping" more reliable so that reference
leak-chasing test runs give sensible results. The previous method of reaping
threads could return successfully while some Thread objects were still
referenced. This also introduces a new private function: ``thread._count()``.
- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
runs the risk of causing the worker thread to fail.
- Issue #7055: test___all__ now greedily detects all modules which have an
__all__ attribute, rather than using a hardcoded and incomplete list.
- Issue #7058: Added save/restore for things like sys.argv and cwd to
runtest_inner in regrtest, with warnings if the called test modifies them,
and a new section in the summary report at the end.
- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
- Issue #6806: test_platform failed under OS X 10.6.0 because ``sw_ver`` leaves
off the trailing 0 in the version number.
- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
Lib/lib-tk/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.
- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
regression tests in parallel, shortening the total runtime.
- Issue #5354: New test support function import_fresh_module() makes it easy to
import both normal and optimised versions of modules. test_heapq and
test_warnings have been adjusted to use it, tests for other modules with both
C and Python implementations in the stdlib can be adjusted to use it over
time.
- Fix test_warnings to no longer reset the warnings filter.
- Fix test_logging to no longer reset the warnings filter.
- Issue #5635: Fix running test_sys with tracing enabled.
- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
should cause a test to be skipped are now done using import_module from test
support, which does the conversion.
2009-03-31 16:57:24 -03:00
- Issue #5083: New 'gui' resource for regrtest.
- Issue #5837: Certain sequences of calls to set() and unset() for
support.EnvironmentVarGuard objects restored the environment variables
incorrectly on __exit__.
- Issue #2389: Array objects are now pickled in a portable manner.
Misc
----

What's New in Python 2.6 release candidate 1?
=============================================
2008-09-12 20:25:57 -03:00
*Release date: 12-Sep-2008*
2008-08-20 23:12:56 -03:00
Core and Builtins
-----------------
- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
PyString_FromFormat or PyErr_Format to display size_t values. The macro
PY_FORMAT_SIZE_T is designed to select the correct format for the OS
``printf`` function, whereas PyString_FromFormat has an independent
implementation and uses "%zd" on all platforms for size_t values.
This makes a difference on win64, where ``printf`` needs "%Id" to display
64bit values.
- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
error.
- Issue #3777: long() applied to a float object now always return a long
object; previously an int would be returned for small values. the __long__
method is allowed to return either an int or a long, but the behaviour of
float objects should not change to respect backward compatibility.
- Issue #3751: str.rpartition would perform a left-partition when called with
a unicode argument.
- Issue #3683: Fix compilation when --without-threads is given.
- Issue #3668: Fix a memory leak with the "s*" argument parser in
PyArg_ParseTuple and friends, which occurred when the argument for "s*"
was correctly parsed but parsing of subsequent arguments failed.
- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
mechanism. In the process, fix a bug where isinstance() and issubclass(),
when given a tuple of classes as second argument, were looking up
__instancecheck__ / __subclasscheck__ on the tuple rather than on each
type object.
- Fix crashes on memory allocation failure found with failmalloc.
- Fix memory leaks found with valgrind and update suppressions file.
- Fix compiler warnings in opt mode which would lead to invalid memory reads.

What's New in Python 2.6 beta 3?
================================
2008-08-20 22:15:08 -03:00
*Release date: 20-Aug-2008*
Core and Builtins
-----------------
2008-08-20 12:01:50 -03:00
- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
extensions do not automatically benefit from the class attribute
cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
to their tp_flags field if they care. This is a backwards
compatibility feature; in 3.0, all types will use the cache by
default.
2008-08-19 22:27:30 -03:00
- Keyword arguments can now follow starred arguments. (``f(a, *args,
keyword=23)`` is now valid syntax.)
- ctypes function pointers that are COM methods have a boolean True
value again.
- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
by denying s# to parse objects that have a releasebuffer procedure,
and introducing s*.
- Issue #3537: Fix an assertion failure when an empty but presized dict
object was stored in the freelist.
- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
ValueError consistently across platforms.
- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
(64bit Unix, for example), unichr() would truncate its argument and return
u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
- Apply security patches from Apple.
- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
PyErr_ExceptionMatches returns 0 when an exception occurs there.
2008-07-25 19:22:08 -03:00
- Issue #1819: function calls with several named parameters are now on
average 35% faster (as measured by pybench).
- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
the python debugger steps into a class statement: the free variables (local
variables defined in an outer scope) would be deleted from the outer scope.
- Issue #2620: Overflow checking when allocating or reallocating memory
was not always being done properly in some python types and extension
modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
all been updated to perform better checks and places in the code that
would previously leak memory on the error path when such an allocation
failed have been fixed.
Library
-------
- Issue #3612: Added some missing basic types in ctypes.wintypes.
- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
symtable.Symbol have been deprecated for removal in 3.0 and the next release.
- Issue #2234: distutils failed for some versions of the cygwin compiler. The
version reported by these tools does not necessarily follow the python
version numbering scheme, so the module is less strict when parsing it.
2008-08-18 09:42:46 -03:00
- Issue #2235: Added Py3k warnings for types which will become unhashable
under the stricter __hash__ inheritance rules in 3.0. Several types
which did not meet the rules for hash invariants and were already
unhashable in 3.0 have now been explicitly flagged as unhashable in
2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
imported into the module but exposed as part of the module's API.
- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2008-08-17 21:36:52 -03:00
- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
- Issue #3575: Incremental decoder's decode function now takes bytearray
by using 's*' instead of 't#'.
- Issue #2222: Fixed reference leak when occurred os.rename()
2008-08-17 06:46:56 -03:00
fails unicode conversion on 2nd parameter. (windows only)
2010-08-01 19:27:39 -03:00
- Issue #2464: urllib2 now supports a malformation in the URL received
in a redirect.
- Silence the DeprecationWarning raised when importing mimetools in
BaseHTTPServer, cgi (and rfc822), httplib.
- Issue #2776: fixed small issue when handling an URL with double slash
after a 302 response in the case of not going through a proxy.
- Issue #2676: in the email package, content-type parsing was hanging on
pathological input because of quadratic or exponential behaviour of a
regular expression.
- Issue #3476: binary buffered reading through the new "io" library is now
thread-safe.
- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
since mimetools itself is deprecated. Because modules are cached, all
subsequent imports of rfc822 will not raise a visible DeprecationWarning.
- Issue #3134: shutil referenced undefined WindowsError symbol.
- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
menu entries were not deleted.
- Copied the implementation of reduce() to _functools.reduce() to have a
version that did not raise a DeprecationWarning under -3.
- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
a MemoryError rather than silently stop the iteration.
- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
to _sre.compile() will now be rejected. This should not affect anybody
since the re.compile() function never generates invalid re-bytecode.
2008-08-08 19:52:51 -03:00
- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
upon first access it can be automatically initialized from the csv file if
it wasn't initialized during instantiation.
- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
the reload() built-in has been removed.
- Changed code in the following modules/packages to remove warnings raised
while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
raised an AttributeError.
2008-07-28 20:35:27 -03:00
- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
asking for a specific length. This problem only affected files opened
using the new "io" module, not the built-in open() function.
2008-07-28 20:35:27 -03:00
- Issue #3449: Update decimal module to use most recent specification
(v. 1.68) and tests (v. 2.58) from IBM.
2010-08-01 19:27:39 -03:00
- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
2008-07-26 21:50:41 -03:00
2010-08-01 19:27:39 -03:00
- Issue #1592: Improve error reporting when operations are attempted
on a closed shelf.
2008-07-23 12:16:45 -03:00
- Deprecate the "ast" parser function aliases.
- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
- Issue #3303: Fix a crash in locale.strcoll() when calling it with
invalid arguments.
- Issue #3302: Fix several crashes when calling locale's gettext functions
with None arguments.
- Issue #3389: Allow resolving dotted names for handlers in logging
configuration files.
- Deprecate the sunaudio module for removal in Python 3.0.
- Issue #3394: zipfile.writestr sets external attributes when passed a
file name rather than a ZipInfo instance, so files are extracted with
mode 0600 rather than 000 under Unix.
- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
argument in python 2.5, this broke code that subclassed Popen to include its
own poll method. Fixed my moving _deadstate to an _internal_poll method.
Build
-----
- Generate the PatternGrammar pickle during "make install".
2008-08-04 09:47:17 -03:00
Documentation
-------------
- Issue #2235: the C API function PyObject_HashNotImplemented and its
interaction with the tp_hash slot (added in 2.6b2) are now documented
2008-08-04 09:47:17 -03:00
- Issue #643841: The language reference now provides more detailed
coverage of the lookup process for special methods. The disclaimers
regarding lack of coverage of new-style classes have also been
removed, since the coverage is now fairly reasonable.
What's New in Python 2.6 beta 2?
================================
*Release date: 17-Jul-2008*
Core and Builtins
-----------------
- Issue #3156: Fix inconsistent behavior of the bytearray type: all
its methods now allow for items objects that can be converted to
an integer using operator.index().
- Issue #3360: Fix incorrect parsing of '020000000000.0', which
produced a ValueError instead of giving the correct float.
- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
- Issue #3008: the float type has a new instance method 'float.hex'
and a new class method 'float.fromhex' to convert floating-point
numbers to and from hexadecimal strings, respectively.
2008-07-15 12:40:22 -03:00
- Issue #2235: __hash__ is once again inherited by default. To allow
collections.Hashable to remain meaningful in the presence of the
default hash implementation (object.__hash__), it is now possible
to explicit block inheritance of hash by setting __hash__=None at
the Python level, or tp_hash=PyObject_HashNotImplemented at the C
level.
- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
the parent module cannot be found while performing an absolute import.
This means that an incorrectly defined __package__ attribute will
now only prevent relative imports in that module rather than causing
all imports from that module to fail.
- Issue #2517: Allow unicode messages in Exceptions again by correctly
bypassing the instance dictionary when looking up __unicode__ on
new-style classes.
- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
set to a custom object whose write() method happens to install
another file in sys.stdout.
- Issue #3088: Corrected a race condition in classes derived from
threading.local: the first member set by a thread could be saved in
another thread's dictionary.
- Issue #3004: Minor change to slice.indices(): the start and stop
arguments are now treated identically, making the behaviour easier
to describe and understand. For example, slice(None, -10,
1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
10, -1).
- Issue #3219: Calling a function with repeated keyword arguments,
f(a=2, a=23), would not cause a syntax error. This was a regression
from 2.4 caused by the switch to the new compiler.
- Issue #2862: Make int and float freelist management consistent with
other freelists. Changes their CompactFreeList apis into
ClearFreeList apis and calls them via gc.collect().
Library
-------
2008-07-16 19:33:18 -03:00
- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
api functions without holding the GIL, which could lead to a fatal
error when they failed.
- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
- Issue #3395: fix reference in test_multiprocessing to old debugInfo method
2008-07-16 19:33:18 -03:00
- Issue #3312: Fix two crashes in sqlite3.
- Issue #1608818: Fix misbehavior in os.listdir() if readdir() fails.
- Issue #3125: Remove copy_reg in multiprocessing and replace it with
ForkingPickler.register() to resolve conflict with ctypes.
- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
- Issue #3313: Fixed a crash when a failed dlopen() call does not set
a valid dlerror() message.
2008-07-15 14:19:50 -03:00
- Issue #3258: Fixed a crash when a ctypes POINTER type to an
incomplete structure was created.
- Issue #3339: dummy_thread.acquire() should not return None.
- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2008-07-10 11:43:31 -03:00
- Issue #3301: Bisect module behaved badly when lo was negative.
- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
both unnecessary (HTTP allows text content to be sent in several forms) and
2008-07-10 11:43:31 -03:00
wrong because the actual transmitted size could differ from the
content-length. The problem had been corrected in the 2.4 branch, but never
merged into trunk.
- Issue #2663: add filtering capability to shutil.copytree().
- Issue #1622: Correct interpretation of various ZIP header fields.
- Issue #1526: Allow more than 64k files to be added to Zip64 file.
- Issue #1746: Correct handling of zipfile archive comments (previously
archives with comments over 4k were flagged as invalid). Allow writing
Zip files with archives by setting the 'comment' attribute of a ZipFile.
- Issue #449227: The rlcompleter module now adds "(" to callable objects
2008-07-10 11:43:31 -03:00
when completed.
- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
handling is now the same as that of other special attributes like __name__).
- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
removal in Python 3.0 in favor of urllib2.urlopen().
- Issue #2113: Fix error in subprocess.Popen if the select system call is
interrupted by a signal.
2008-07-10 11:43:31 -03:00
- Issue #3309: Fix bz2.BZFile iterator to release its internal lock
properly when raising an exception due to the bz2file being closed.
Prevents a deadlock.
- Issue #3094: httplib.HTTPSConnection Host: headers no longer include the
redundant ":443" port number designation when the connection is using the
default https port (443).
2008-07-17 00:13:05 -03:00
- Issue #874900: after an os.fork() call the threading module state is cleaned
up in the child process to prevent deadlock and report proper thread counts
if the new process uses the threading module.
Tests
-----
- test.test_support.catch_warning now keeps track of all warnings it sees
and is now better documented. Explicit unit tests for this context manager
have been added to test_warnings.
Build
-----
- Issue #3215: Build sqlite3 as sqlite3.dll, not sqlite3.pyd.
Documentation
-------------
- Document that robotparser has been renamed to urllib.robotparser in
Python 3.0.
- Document that urlparse has been renamed to urllib.parse in Python 3.0.
- Document that urllib2 is split across multiple modules and renamed in
Python 3.0.
- Document that urllib is split across multiple modules and renamed in
Python 3.0.
What's New in Python 2.6 beta 1?
================================
2008-06-18 22:48:07 -03:00
*Release date: 18-June-2008*
Core and Builtins
-----------------
- Issue #3211: warnings.warn_explicit() did not guard against its 'registry'
argument being anything other than a dict or None. Also fixed a bug in error
handling when 'message' and 'category' were both set to None, triggering a
bus error.
- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
holds the last (strong) reference to its referent.
2008-06-11 15:55:38 -03:00
- Add future_builtins.ascii().

- New environment variable PYTHONIOENCODING.
2008-05-20 05:11:19 -03:00
- Patch #2488: Add sys.maxsize.
- Issue #2353: file.xreadlines() now emits a Py3k warning.
- Issue #2863: generators now have a ``gen.__name__`` attribute that
equals ``gen.gi_code.co_name``, like ``func.__name___`` that equals
``func.func_code.co_name``. The repr() of a generator now also
contains this name.
2008-05-14 03:34:15 -03:00
- Issue #2831: enumerate() now has a ``start`` argument.
- Issue #2801: fix bug in the float.is_integer method where a
ValueError was sometimes incorrectly raised.
- Issue #2790: sys.flags was not properly exposing its bytes_warning
attribute.
- Issue #2196: hasattr() now lets exceptions which do not inherit
Exception (KeyboardInterrupt, and SystemExit) propagate instead of
ignoring them.
- Added checks for integer overflows, contributed by Google. Some are
only available if asserts are left in the code, in cases where they
can't be triggered from Python code.
Extension Modules
-----------------
2008-08-20 11:57:20 -03:00
- Issue #1179: [CVE-2007-4965] Integer overflow in imageop module.

2008-06-22 10:39:11 -03:00
- Issue #2138: Add factorial() to the math module.
2008-06-09 03:54:45 -03:00

- Issue #2858: Fix potential memory corruption when
bsddb.db.DBEnv.lock_get and other bsddb.db object constructors
raised an exception.
2008-05-25 05:32:04 -03:00
- Issue #2669: bsddb/__init__.py iteration no longer silently fails when
the database has changed size during iteration. It now raises a
RuntimeError in the same manner as a dictionary.
- Issue #2870: cmathmodule.c compile error.
- Added a threading.Thread.ident property.
Library
-------
- logging.config: Removed out-of-date comment in _install_handlers and
used issubclass in place of equality comparison of classes.
- Issue #2722: Now the os.getcwd() supports very long path names.
- Issue #2888: Fixed the behaviour of pprint when working with nested

sense).
- Issue #1817: cgi now correctly handles the querystring on POST requests
2008-06-19 19:41:08 -03:00
- Issue #3136: fileConfig()'s disabling of old loggers is now conditional via
an optional disable_existing_loggers parameter, but the default value is
such that the old behaviour is preserved. Thanks to Leandro Lucarella for
the patch.
2008-06-17 08:04:02 -03:00
- Issue #3126: StreamHandler and FileHandler check before calling "flush" and
"close" that the stream object has these, using hasattr (thanks to bobf for
the patch).

deleting old log files (filename only instead of full path).
- Issue #1775025: You can now specify zipfile members to open(),
read() or extract() via a ZipInfo instance. This allows handling
duplicate filenames in zipfiles.
2008-05-17 14:57:01 -03:00
- Issue #961805: Fix Text.edit_modified() in Tkinter.
- Issue #1793: Function ctypes.util.find_msvcrt() added that returns
the name of the C runtime library that Python uses.
ctypes.util.find_library(name) now call this function when name is
'm' or 'c'.

What's New in Python 2.6 alpha 3?
2008-03-01 13:11:41 -04:00
=================================
2008-05-08 10:16:19 -03:00
*Release date: 08-May-2008*
2008-03-01 13:11:41 -04:00
Core and builtins
-----------------
2008-03-25 04:56:27 -03:00
2008-04-30 16:47:09 -03:00
- Issue #2719: backported the ``next()`` builtin from Python 3.
- Issue #2681: The octal literal ``0o8`` was incorrecly acctepted. Now
it properly raises a SyntaxError.
- Issue #2617: Reserved -J and -X arguments for Jython, IronPython and
other implementations of Python.
- Implemented PEP 370: Per user site-packages directory.

Extension Modules
-----------------
2008-04-03 22:34:41 -03:00
- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
two handlers that derive the same default base class.
- Added kill, terminate and send_signal(sig) to subprocess.Popen.
- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
the cmath module.
- Four new methods were added to the math and cmath modules: acosh,
asinh, atanh and log1p.
- zlib.decompressobj().flush(value) no longer crashes the interpreter
when passed a value less than or equal to zero.
- Issue #1631171: Re-implement the 'warnings' module in C (the
original Python code has been kept as backup). This will allow for
using the 'warning's machinery in such places as the parser where
use of pure Python code is not possible. Both the ``showarning()``
and ``formatwarning()`` gain an optional 'line' argument which is
not called by default for backwards-compatibility reasons. Setting
``warnings.showwarning()`` to an implementation that lacks support
for the ``line`` argument will raise a DeprecationWarning.
2008-04-03 22:34:41 -03:00
Library
-------
- The audiodev module has been deprecated for removal in Python 3.0.
- Issue #2750: Add the 'json' package. Based on simplejson 1.9 and
contributed by Bob Ippolito.
- Issue #1734346: Support Unicode file names for zipfiles.
- Issue #2581: distutils: Vista UAC/elevation support for
bdist_wininst.
- Issue #2635: Fix bug in 'fix_sentence_endings' textwrap.fill option,
where an extra space was added after a word containing (but not
ending in) '.', '!' or '?'.
- Add from_buffer() and from_buffer_copy() class methods to ctypes
data types.
2008-04-25 00:40:17 -03:00
- Issue #2682: ctypes callback functions no longer contain a cyclic
reference to themselves.
2008-04-22 05:11:33 -03:00
- The getpass module has been improved on Unix. It now uses /dev/tty
by default and uses stderr instead of stdout. A GetPassWarning is
issued when input echo cannot be controlled.
2008-04-18 17:35:46 -03:00
- Issue #2014: Allow XML-RPC datetime objects to have dates before
1900-01-01.
- Issue #2439: Added new function pkgutil.get_data(), which is a
convenience wrapper for the PEP 302 get_data() API.
- Issue #2616: The ctypes.pointer() and ctypes.POINTER() functions are
now implemented in C for better performance.
- Issue #2408: The ``_types`` module, which was used as in
implementation detail of the public ``types`` module, has been
removed and replaced by pure python code.
2008-04-08 20:10:07 -03:00
- Issue #2513: distutils on Windows is now capable of cross-compiling
extension modules between 32 and 64 bit platforms. See the distutls
build documentation for more information.
- Issue #815646: Individual file objects may now be used from multiple
threads at once without fear of crashing the Python interpreter. If
file.close() is called while an object is in use by another thread
an IOError exception will be raised and the file will not be closed.
- The bundled libffi copy is now in sync with the recently released
libffi3.0.5 version, apart from some small changes to
Modules/_ctypes/libffi/configure.ac.
- Issue #2385: distutils.core.run_script() makes __file__ available,
so the controlled environment will more closely mirror the typical
script environment. This supports setup.py scripts that refer to
data files.
2008-04-03 22:34:41 -03:00
Tests
-----
- Issue #2550: The approach used by client/server code for obtaining
ports to listen on in network-oriented tests has been refined in an
effort to facilitate running multiple instances of the entire
regression test suite in parallel without issue.
test_support.bind_port() has been fixed such that it will always
return a unique port -- which wasn't always the case with the
previous implementation, especially if socket options had been set
that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
new implementation of bind_port() will actually raise an exception
if it is passed an AF_INET/SOCK_STREAM socket with either the
SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
the socket it's been passed. This currently only applies to
Windows. This option prevents any other sockets from binding to the
host/port we've bound to, thus removing the possibility of the
'non-deterministic' behaviour, as Microsoft puts it, that occurs
when a second SOCK_STREAM socket binds and accepts to a host/port
that's already been bound by another socket. The optional preferred
port parameter to bind_port() has been removed. Under no

This method should only be used for obtaining an unused port in order to pass to an external program (i.e. the -accept [port] argument to openssl's s_server mode) or as a parameter to a server-oriented class that doesn't give you direct access to the underlying socket used. Finally, test_support.HOST has been introduced, which should be used for the host argument of any relevant socket calls (i.e. bind and connect).

tracing function set by sys.settrace is still active and happens to
call threading.currentThread().
- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
cannot be executed.
- The compilation of a class nested in another class used to leak one
reference on the outer class name.
- Patch #1810: compile() can now compile _ast trees as returned by

- Issue #2355: add Py3k warning for buffer().
- Issue #1477: With narrow Unicode builds, the unicode escape sequence
\Uxxxxxxxx did not accept values outside the Basic Multilingual
Plane. This affected raw unicode literals and the

memory usage in some circumstances.
- PEP 3127: octal literals now start with "0o". Old-style octal
literals are still valid. There are binary literals with a prefix of
"0b". This also affects int(x, 0).
- Issue #2359: Adding deprecation warnings for array.{read,write}.
- Issue #1779871: GNU gcc can now build Python on OS X because the
flags -Wno-long-double, -no-cpp-precomp, and -mno-fused-madd are no
longer passed.

- Backport of Python 3.0's io module.
- Issue #2482: Make sure that the coefficient of a Decimal is always
stored as a str instance, not as a unicode instance. This ensures
that str(Decimal) is always an instance of str.
- Issue #2478: fix failure of decimal.Decimal(0).sqrt()
- Issue #2432: give DictReader the dialect and line_num attributes
advertised in the docs.
- Issue #2460: Make Ellipsis object copyable.
- Issue #1681432: Add triangular distribution to the random module

in the WWW-Authenticate header.
- Issue #2434: Enhanced platform.win32_ver() to also work on Python
installation which do not have the win32all package installed.
- Added support to platform.uname() to also report the machine and
processor information on Windows XP and later. As a result,
platform.machine() and platform.processor() will report this
information as well.
- The library implementing the 2to3 conversion, lib2to3, was added to
the standard distribution.
2008-03-19 01:43:46 -03:00
- Issue #1747858: Fix chown to work with large uid's and gid's on
64-bit platforms.
2008-03-18 17:40:01 -03:00
- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
values on 32-bit vs. 64-bit python interpreters. Both were correct,
but they now both return a signed integer object for consistency.
2008-03-15 13:07:11 -03:00
- Issue #1158: add %f format (fractions of a second represented as
microseconds) to datetime objects. Understood by both strptime and
strftime.
- Issue #705836: struct.pack(">f", x) now raises OverflowError on all
platforms when x is too large to fit into an IEEE 754 float;
previously it only raised OverflowError on non IEEE 754 platforms.
- Issues #2166, #1741 and #1531505: now distutils deals with HOME
correctly under win32
- Patch #1858: distutils: added multiple server support in .pypirc
- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
optional: it defaults to the traceback of the exception that is
currently being handled (is mandatory to be in the middle of an
exception, otherwise it raises ValueError).
- Issue #1193577: A .shutdown() method has been added to SocketServers
which terminates the .serve_forever() loop.
- Issue #2220: handle rlcompleter attribute match failure more
gracefully.
- Issue #2225: py_compile, when executed as a script, now returns a
non- zero status code if not all files could be compiled
successfully.
- Bug #1725737: In distutils' sdist, exclude RCS, CVS etc. also in the
2008-03-06 03:34:52 -04:00
root directory, and also exclude .hg, .git, .bzr, and _darcs.
- Issue #1872: The struct module typecode for _Bool has been changed
from 't' to '?'.
2008-03-05 10:53:39 -04:00
- The bundled libffi copy is now in sync with the recently released
libffi3.0.4 version, apart from some small changes to
Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
files are used. On all linux systems the --with-system-ffi
configure option defaults to "yes".
2008-03-05 10:53:39 -04:00
- Issue #1577: shutil.move() now calls os.rename() if the destination
is a directory instead of copying-then-remove-source.

What's New in Python 2.6 alpha 1?
=================================
2008-02-29 22:53:36 -04:00
*Release date: 29-Feb-2008*
2006-08-18 00:57:54 -03:00
Core and builtins
-----------------
2008-02-29 22:45:07 -04:00
- Issue #2051: pyc and pyo files are no longer created with permission
2008-02-29 22:23:38 -04:00
644. The mode is now inherited from the py file.
- Issue #2067: file.__exit__() now calls subclasses' close() method.
- Patch #1759: Backport of PEP 3129 class decorators.
- Issue #1881: An internal parser limit has been increased. Also see
2010-08-01 19:27:39 -03:00
issue #215555 for a discussion.
- Added the future_builtins module, which contains hex() and oct().
These are the PEP 3127 version of these functions, designed to be
compatible with the hex() and oct() builtins from Python 3.0. They
differ slightly in their output formats from the existing, unchanged
Python 2.6 builtins. The expected usage of the future_builtins
module is:
from future_builtins import hex, oct
- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
exponents for exponents with absolute value < 100. Follows C99
standard. This is a change on Windows, which would use 3 digits.
Also, added 'n' to the formats that PyOS_ascii_formatd understands,
so that any alterations it does to the resulting string will be
available in stringlib/formatter.h (for float.__format__).
2008-02-19 09:21:56 -04:00
- Implemented PEP 3101, Advanced String Formatting. This adds a new
builtin format(); a format() method for str and unicode; a
__format__() method to object, str, unicode, int, long, float, and
datetime; the class string.Formatter; and the C API
PyObject_Format().
- Fixed several potential crashes, all caused by specially crafted
__del__ methods exploiting objects in temporarily inconsistent
state.
- Issue #2115: Important speedup in setting __slot__ attributes. Also
prevent a possible crash: an Abstract Base Class would try to access
a slot on a registered virtual subclass.
- Fixed repr() and str() of complex numbers with infinity or nan as
real or imaginary part.
- Clear all free lists during a gc.collect() of the highest generation
in order to allow pymalloc to free more arenas. Python may give back
memory to the OS earlier.
- Issue #2045: Fix an infinite recursion triggered when printing a
subclass of collections.defaultdict, if its default_factory is set
to a bound method.
- Fixed a minor memory leak in dictobject.c. The content of the free
list was not freed on interpreter shutdown.
2010-03-07 11:23:59 -04:00
- Limit free list of method and built-in function objects to 256
entries each.
- Patch #1953: Added ``sys._compact_freelists()`` and the C API
functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
to compact the internal free lists of pre-allocted ints and floats.
- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
calls. Python expected the return type int but the fork familie
returns pi_t.
- Issue #1678380: Fix a bug that identifies 0j and -0j when they
appear in the same code unit.
- Issue #2025: Add tuple.count() and tuple.index() methods to comply
with the collections.Sequence API.
- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
linebreak detection
- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
the internal lookup cache for ref leak tests.
- Patch #1473257: generator objects gain a gi_code attribute. This is
the same object as the func_code attribute of the function that
produced the generator.
- Issue #1920: "while 0" statements were completely removed by the
compiler, even in the presence of an "else" clause, which is
supposed to be run when the condition is false. Now the compiler
correctly emits bytecode for the "else" suite.
2008-01-24 18:59:25 -04:00
- A few crashers fixed: weakref_in_del.py (issue #1377858);
loosing_dict_ref.py (issue #1303614, test67.py);
borrowed_ref_[34].py (not in tracker).
- Issue #1069410: The "can't load dll" message box on Windows is
suppressed while an extension is loaded by calling SetErrorMode in
dynload_win.c. The error is still reported properly.
- Issue #1915: Python compiles with --enable-unicode=no again. However
several extension methods and modules do not work without unicode
support.
2008-01-21 14:36:51 -04:00
- Issue #1882: when compiling code from a string, encoding cookies in the
second line of code were not always recognized correctly.
- Issue #1679: "0x" was taken as a valid integer literal.
- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
added.
- sys.float_info / PyFloat_GetInfo: The floating point information
object was converted from a dict to a specialized structseq object.
- Patch #1816: Added sys.flags structseq. It exposes the status of
most command line arguments and PYTHON* environment variables.
2008-01-13 23:42:48 -04:00
- Objects/structseq.c: Implemented new structseq representation. The
patch makes structseqs (e.g. the return value of os.stat) more
readable.
- Patch #1700288: added a type attribute cache that caches method
accesses, resulting in speedups in heavily object-oriented code.
- Bug #1776: __import__() no longer accepts filenames on any platform.
The first parameter to __import__() must be a valid module name.
- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
envvar and sys.dont_write_bytecode attribute. All these can be set
to forbid Python to attempt to write compiled bytecode files.
- Improve some exception messages when Windows fails to load an
extension module. Now we get for example '%1 is not a valid Win32
application' instead of 'error code 193'.
- Bug #1481296: Fixed long(float('nan')) != 0L.
- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
y) functions.
2008-01-03 16:23:15 -04:00
- Issue #1635: Platform independent creation and representation of NaN
and INF. float("nan"), float("inf") and float("-inf") now work on
every platform with IEEE 754 semantics.
- Compiler now generates simpler and faster code for dictionary
literals. The oparg for BUILD_MAP now indicates an estimated
dictionary size. There is a new opcode, STORE_MAP, for adding
entries to the dictionary.
- Issue #1638: %zd configure test fails on Linux.
- Issue #1620: New property decorator syntax was modifying the
decorator in place instead of creating a new decorator object.
- Issue #1538: Avoid copying string in split/rsplit if the split char
is not found.
2007-12-05 09:27:20 -04:00
- Issue #1553: An erroneous __length_hint__ can make list() raise a
2007-12-05 08:52:34 -04:00
SystemError.
2007-12-03 08:55:17 -04:00
- PEP 366: Allow explicit relative imports when executing modules
inside packages with the -m switch via a new module level
__package__ attribute.
- Issue #1402: Fix a crash on exit, when another thread is still
running, and if the deallocation of its frames somehow calls the
PyGILState_Ensure() / PyGILState_Release() functions.
2007-11-30 16:37:22 -04:00
- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
attribute of an empty cell object.
- Issue #1460: The utf-7 incremental decoder did not accept truncated
input. It now correctly saves its state between chunks of data.
2007-11-20 21:38:26 -04:00
- Patch #1739468: Directories and zipfiles containing a __main__.py
file can now be directly executed by passing their name to the
interpreter. The directory/zipfile is automatically inserted as the
first entry in sys.path.
- Issue #1265: Fix a problem with sys.settrace, if the tracing
function uses a generator expression when at the same time the
executed code is closing a paused generator.
2007-11-07 22:52:43 -04:00
- sets and frozensets now have an isdisjoint() method.
- optimize the performance of builtin.sum().
- Fix warnings found by the new version of the Coverity checker.
2010-03-07 11:23:59 -04:00
- The enumerate() built-in function is no longer bounded to sequences
smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
automatically shifts from ints to longs.
- Issue #1686386: Tuple's tp_repr did not take into account the
possibility of having a self-referential tuple, which is possible
from C code. Nor did object's tp_str consider that a type's tp_str
could do something that could lead to an inifinite recursion.
Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
issues.
- Issue #1164: It was possible to trigger deadlock when using the
'print' statement to write to a file since the GIL was not released
as needed. Now PyObject_Print() does the right thing along with
various tp_print implementations of the built-in types and those in
the collections module.
- Issue #1147: Exceptions were directly allowing string exceptions in
their throw() method even though string exceptions no longer
allowed.
- Issue #1096: Prevent a segfault from getting the repr of a very
deeply nested list by using the recursion counter.
- Issue #1202533: Fix infinite recursion calls triggered by calls to
PyObject_Call() never calling back out to Python code to trigger
recursion depth updates/checks. Required the creation of a static
RuntimeError instance in case normalizing an exception put the
recursion check value past its limit. Fixes crashers
infinite_rec_(1|2|4|5).py.
- Patch #1031213: Decode source line in SyntaxErrors back to its
original source encoding.
- Patch #1673759: add a missing overflow check when formatting floats
with %G.
- Prevent expandtabs() on string and unicode objects from causing a
segfault when a large width is passed on 32-bit platforms.
- Issue #1733488: Fix compilation of bufferobject.c on AIX.
- Issue #1722485: remove docstrings again when running with -OO.
- Add new attribute names for function objects. All the func_* become
__*__ attributes. (Some already existed, e.g., __doc__ and
__name__.)
- Add -3 option to the interpreter to warn about features that are
deprecated and will be changed/removed in Python 3.0.
- Patch #1686487: you can now pass any mapping after '**' in function
calls.
- except clauses may now be spelled either "except E, target:" or
"except E as target:". This is to provide forwards compatibility
with Python 3.0.
- Deprecate BaseException.message as per PEP 352.
- Issue #1303614: don't expose object's __dict__ when the dict is
2010-03-07 11:23:59 -04:00
inherited from a built-in base.
2007-05-06 14:53:37 -03:00
- When __slots__ are set to a unicode string, make it work the same as
setting a plain string, ie don't expand to single letter identifiers.
2007-04-11 15:40:58 -03:00
- Request #1191699: Slices can now be pickled.
- Request #1193128: str.translate() now allows a None argument for
translations that only remove characters without re-mapping the
remaining characters.
- Patch #1682205: a TypeError while unpacking an iterable is no longer
masked by a generic one with the message "unpack non-sequence".
- Remove unused file Python/fmod.c.
- Bug #1683368: The object.__init__() and object.__new__() methods are
now stricter in rejecting excess arguments. The only time when
either allows excess arguments is when it is not overridden and the
other one is. For backwards compatibility, when both are
overridden, it is a deprecation warning (for now; maybe a Py3k
2007-03-23 16:39:01 -03:00
warning later). Also, type.__init__() insists on the same signature
as supported by type.__new__().
- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
object to complex using its __complex__() method before falling back
to the __float__() method. Therefore, the functions in the cmath
module now can operate on objects that define a __complex__()
method.
- Patch #1623563: allow __class__ assignment for classes with
__slots__. The old and the new class are still required to have the
same slot names.
- Patch #1642547: Fix an error/crash when encountering syntax errors
in complex if statements.
- Patch #1462488: Python no longer segfaults when
``object.__reduce_ex__()`` is called with an object that is faking
its type.
- Patch #1680015: Don't modify __slots__ tuple if it contains an
unicode name.
- Patch #1444529: the builtin compile() now accepts keyword arguments.
- Bug #1678647: write a newline after printing an exception in any
case, even when converting the value to a string failed.
- The dir() function has been extended to call the __dir__() method on
its argument, if it exists. If not, it will work like before. This
allows customizing the output of dir() in the presence of a
__getattr__().
- Patch #922167: Python no longer segfaults when faced with infinitely
self-recursive reload() calls (as reported by bug #742342).
- Patch #1675981: remove unreachable code from ``type.__new__()``
method.
- Patch #1491866: change the complex() constructor to allow
parthensized forms. This means complex(repr(x)) now works instead of
raising a ValueError.
- Patch #703779: unset __file__ in __main__ after running a file. This
makes the filenames the warning module prints much more sensible
when a PYTHONSTARTUP file is used.
- Variant of patch #697613: don't exit the interpreter on a SystemExit
exception if the -i command line option or PYTHONINSPECT environment
variable is given, but break into the interactive interpreter just
like on other exceptions or normal program exit.
- Patch #1638879: don't accept strings with embedded NUL bytes in
long().
- Bug #1674503: close the file opened by execfile() in an error
condition.
- Patch #1674228: when assigning a slice (old-style), check for the
sq_ass_slice instead of the sq_slice slot.
- When printing an unraisable error, don't print exceptions. before
the name. This duplicates the behavior whening normally printing
exceptions.
- Bug #1653736: Properly discard third argument to
slot_nb_inplace_power.
- PEP 352: Raising a string exception now triggers a TypeError.
Attempting to catch a string exception raises DeprecationWarning.
- Bug #1377858: Fix the segfaulting of the interpreter when an object
created a weakref on itself during a __del__ call for new-style
classes (classic classes still have the bug).
- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
frame's thread state.
- patch #1630975: Fix crash when replacing sys.stdout in
sitecustomize.py.
- Prevent seg fault on shutdown which could occur if an object raised
a warning.
- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main, to
avoid relying on atexit.
- Bug #1590891: random.randrange don't return correct value for big
number.
- Patch #1586791: Better exception messages for some operations on
strings, tuples and lists.
- Bug #1067760: Deprecate passing floats to file.seek.
2006-11-08 02:48:36 -04:00
- Bug #1591996: Correctly forward exception in instance_contains().
- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
- Bug #1576657: when setting a KeyError for a tuple key, make sure
that the tuple isn't used as the "exception arguments tuple".
- Bug #1565514: SystemError not raised on too many nested blocks.
- Bug #1576174: WindowsError now displays the windows error code
again, no longer the posix error code.
- Patch #1549049: Support long values in structmember, issue warnings
if the assigned value for structmember fields gets truncated.
- Update the peephole optimizer to remove more dead code (jumps after
returns) and inline unconditional jumps to returns.
- Bug #1545497: when given an explicit base, int() did ignore NULs
embedded in the string to convert.
2006-10-08 04:11:54 -03:00
- Bug #1569998: break inside a try statement (outside a loop) is now
recognized and rejected.
- list.pop(x) accepts any object x following the __index__ protocol.
- A number of places, including integer negation and absolute value,
were fixed to not rely on undefined behaviour of the C compiler
anymore.
- Bug #1566800: make sure that EnvironmentError can be called with any
number of arguments, as was the case in Python 2.4.
- Patch #1567691: super() and new.instancemethod() now don't accept
keyword arguments any more (previously they accepted them, but
didn't use them).
- Fix a bug in the parser's future statement handling that led to
"with" not being recognized as a keyword after, e.g., this
statement: from __future__ import division, with_statement
- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).
- Fix %zd string formatting on Mac OS X so it prints negative numbers.
- Allow exception instances to be directly sliced again.
- Bug #1551432: Exceptions do not define an explicit __unicode__
method. This allows calling unicode() on exceptions classes
directly to succeed.
- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
Also make sure that every exception class has __module__ set to
'exceptions'.
- Bug #1550983: emit better error messages for erroneous relative
imports (if not in package and if beyond toplevel package).
- Overflow checking code in integer division ran afoul of new gcc
optimizations. Changed to be more standard-conforming.
- Patch #1542451: disallow continue anywhere under a finally.
- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
- The return tuple from str.rpartition(sep) is (tail, sep, head) where
head is the original string if sep was not found.
- Bug #1520864: unpacking singleton tuples in list comprehensions and
generator expressions (x for x, in ... ) works again. Fixing this
problem required changing the .pyc magic number. This means that
.pyc files generated before 2.5c2 will be regenerated.
- ``with`` and ``as`` are now keywords.
- Bug #1664966: Fix crash in exec if Unicode filename can't be
decoded.
- Issue #1537: Changed GeneratorExit's base class from Exception to
BaseException.
- Issue #1703448: A joined thread could show up in the
threading.enumerate() list after the join() for a brief period until
it actually exited.

- Issue #1492: The content type of BaseHTTPServer error messages can
now be overridden.
- Issue #1781: ConfigParser now does not let you add the "default" section
(ignore-case)
- Removed uses of dict.has_key() from distutils, and uses of
callable() from copy_reg.py, so the interpreter now starts up

statement after the first iteration. Now it correctly steps on the
expression, and breakpoints on the "while" statement are honored on
each loop.
- Issue #1765140: add an optional delay argument to FileHandler and
its subclasses. Defaults to false (existing behaviour), but if true,
defers opening the file until the first call to emit().
- The pprint module now supports sets and frozensets.
- Issue #1221598: add optional callbacks to ftplib.FTP's storbinary()

(as opposed to the command line) will now write file names ending in
".cpp" too.
- As specified in RFC 2616, an HTTP response like 2xx indicates that
the client's request was successfully received, understood, and

- Bug #1290505: time.strptime's internal cache of locale information
is now properly recreated when the locale is changed.
- Patch #1685563: remove (don't add) duplicate paths in
distutils.MSVCCompiler.

- Patch #1630118: add a SpooledTemporaryFile class to tempfile.py.
- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
to True (which is not the default), it visits symlinks pointing to
directories.
- Bug #1681228: the webbrowser module now correctly uses the default
GNOME or KDE browser, depending on whether there is a session of one
of those present. Also, it tries the Windows default browser before

- Patch #1681153: the wave module now closes a file object it opened if
initialization failed.

AttributeError instead of an IOError when the server's response
didn't contain a valid HTTP status line.
- Patch #957650: "%var%" environment variable references are now
properly expanded in ntpath.expandvars(), also "~user" home
directory references are recognized and handled on Windows.
- Patch #1429539: pdb now correctly initializes the __main__ module
for the debugged script, which means that imports from __main__ work
correctly now.
- The nonobvious commands.getstatus() function is now deprecated.
- Patch #1393667: pdb now has a "run" command which restarts the
debugged Python program, optionally with different arguments.
- Patch #1649190: Adding support for _Bool to ctypes as c_bool.
- Patch #1530482: add pydoc.render_doc() which returns the
documentation for a thing instead of paging it to stdout, which
pydoc.doc() does.
- Patch #1533909: the timeit module now accepts callables in addition
to strings for the code to time and the setup code. Also added two
convenience functions for instantiating a Timer and calling its
methods.
- Patch #1537850: tempfile.NamedTemporaryFile now has a "delete"
parameter which can be set to False to prevent the default
delete-on-close behavior.
- Patch #1581073: add a flag to textwrap that prevents the dropping of
whitespace while wrapping.
- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
are set for invalid interpolation sequences that would lead to
errors on reading back those values.
- Added support for the POSIX.1-2001 (pax) format to
tarfile.py. Extended and cleaned up the test suite. Added a new
testtar.tar.
This is the implementation of POSIX.1-2001 (pax) format read/write support. The TarInfo class now contains all necessary logic to process and create tar header data which has been moved there from the TarFile class. The fromtarfile() method was added. The new path and linkpath properties are aliases for the name and linkname attributes in correspondence to the pax naming scheme. The TarFile constructor and classmethods now accept a number of keyword arguments which could only be set as attributes before (e.g. dereference, ignore_zeros). The encoding and pax_headers arguments were added for pax support. There is a new tarinfo keyword argument that allows using subclassed TarInfo objects in TarFile. The boolean TarFile.posix attribute is deprecated, because now three tar formats are supported. Instead, the desired format for writing is specified using the constants USTAR_FORMAT, GNU_FORMAT and PAX_FORMAT as the format keyword argument. This change affects TarInfo.tobuf() as well. The test suite has been heavily reorganized and partially rewritten. A new testtar.tar was added that contains sample data in many formats from 4 different tar programs. Some bugs and quirks that also have been fixed: Directory names do no longer have a trailing slash in TarInfo.name or TarFile.getnames(). Adding the same file twice does not create a hardlink file member. The TarFile constructor does no longer need a name argument. The TarFile._mode attribute was renamed to mode and contains either 'r', 'w' or 'a'.
2007-03-13 07:47:19 -03:00
- Patch #1449244: Support Unicode strings in

TCPServer, SimpleXMLRPCServer and DocXMLRPCServer.
- Bug #1531963: Make SocketServer.TCPServer's server_address always be
equal to calling getsockname() on the server's socket. Fixed by
2007-03-09 23:35:34 -04:00
patch #1545011.
- Patch #742598: Add .timeout attribute to SocketServer that calls
.handle_timeout() when no requests are received.
- Bug #1651235: When a tuple was passed to a ctypes function call,
Python would crash instead of raising an error.
- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
returned string up to the first NUL character.

module. The KeyError raised by Zipfile.getinfo for nonexistent
names now has a descriptive message.
- Bug #1115886: os.path.splitext('.cshrc') gives now ('.cshrc', '').
- unittest now verifies more of its assumptions. In particular,
TestCase and TestSuite subclasses (not instances) are no longer
accepted in TestSuite.addTest(). This should cause no
incompatibility since it never made sense with ordinary subclasses
-- the failure just occurred later, with a more cumbersome
exception.
2007-03-08 14:37:31 -04:00
- Patch #787789: allow to pass custom TestRunner instances to
unittest's main() function.

with statement compiled by the compiler package crashed the
interpreter.

with RFC 3207 and forgets any knowledge obtained from the server not
obtained from the TLS negotiation itself. Patch contributed by Bill
Fenner.
2008-01-17 04:03:17 -04:00
- Issue #1339: The smtplib.SMTP class has been refactored a bit such
that the SMTP.starttls() caller no longer needs to call ehlo()
beforehand. SMTP.starttls() now raises an exception of the server
does not claim to support starttls. Adds the
SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
Fenner.
- Patch #1089358: Add signal.siginterrupt, a wrapper around

and ungetwch. The functions accept or return unicode.
- os.access now returns True on Windows for any existing directory.
- Added warnpy3k function to the warnings module.

intended for RECNO databases.
- pybsddb.sf.net Bug #477182: Load the database flags at database open
time so that opening a database previously created with the DB_DUP
or DB_DUPSORT flag set will keep the proper behavior on subsequent
opens. Specifically: dictionary assignment to a DB object will
replace all values for a given key when the database allows
duplicate values. DB users should use DB.put(k, v) when they want
to store duplicates; not DB[k] = v.
- Add the bsddb.db.DBEnv.lock_id_free method.
- Bug #1686475: Support stat'ing open files on Windows again.
- Patch #1185447: binascii.b2a_qp() now correctly quotes binary

fails.
- Speed up function calls into the math module.
- Bug #1588217: don't parse "= " as a soft line break in binascii's

2006-09-27 13:37:30 -03:00
- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
mode by only placing a timeout on the select() if an input hook has
been defined. This prevents an interactive Python from waking up 10
times per second. Patch by Richard Boulton.
2007-03-17 19:33:35 -03:00

-----
- Refactor test_logging to use unittest.
- Refactor test_profile and test_cprofile to use the same code to
profile.
- Make test_runpy reentrant by fixing _check_module to clear out any
module being tested. Was causing an error by __import__ doing a
reload on the second run and thus suppressing bytecode recreation.

- Tools/scripts/reindent.py now creates the backup file using
shutil.copy to preserve user/group and permissions. Added also a
--nobackup option to not create the backup if the user is concerned
2010-08-01 19:27:39 -03:00
regarding this. Check issue #1050828 for more details.
- Tools/scripts/win_add2path.py was added. The simple script modifes
the PATH environment var of the HKCU tree and adds the python bin
and script directory.
2007-08-28 22:33:45 -03:00
- Tools/18n/pygettext.py was added to the list of scripts installed by
Tools/scripts/setup.py (tracker item 642309).

newer GCC versions may optimize away overflow buffer overflow checks
without this option!
- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
- Add a FAST_LOOPS build option that speeds-up looping by trading away
periodic threadstate and signal checking in tight loops. By

environment.
2006-08-18 00:57:54 -03:00
C API
-----
- Unified naming convention for free lists and their limits. All free
lists in Object/ are named ``free_list``, the counter ``numfree``
and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
#ifndef block.
- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
to ``PyTuple_SetItem``, it can be used to populate a brand new
frozenset; but it does not steal a reference to the added item.
- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
PyLong_FromSsize_t public functions.

- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
``PyFloat_GetInfo()`` to the float API.
- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
of w# format code incorrectly truncated the length to an int, even
when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
incorrect results with huge strings.
- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
Py_TYPE and Py_REFCNT.
- PEP 3123: Provide forward compatibility with Python 3.0, while
keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
and PyVarObject_HEAD_INIT.
- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
defined.
- Patch #1733960: Allow T_LONGLONG to accept ints.
- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
- Added a new API function ``PyImport_ImportModuleNoBlock``.
- Bug #1637022: Prefix AST symbols with _Py_.
- Fix some leftovers from the conversion from int to Py_ssize_t
(relevant to strings and sequences of more than 2**31 items).
- Make _PyGILState_NoteThreadState() static, it was not used anywhere
outside of pystate.c and should not be necessary.
- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
absolute imports. In earlier versions they might have used relative
imports under some conditions.
- Added case insensitive comparison methods ``PyOS_stricmp(char*,
char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
macro so it can be used as an expression.
2006-08-18 00:57:54 -03:00
Windows
-------
- Patch #1706: Drop support for Win9x, WinME and NT4. Python now

builds.
- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
_CRT_NONSTDC_NO_DEPRECATE.
- Bug #1216: Restore support for Visual Studio 2002.

Mac
---
- cfmfile now raises a DeprecationWarning.
- buildtools now raises a DeprecationWarning.
- Removed the macfs module. It had been deprecated since Python 2.5.
This lead to the deprecation of macostools.touched() as it relied
solely on macfs and was a no-op under OS X.
