Florent Xiclunac2279652012-02-12 14:49:03 +0100326- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100327 has left two versions of customize_compiler, the original in
328 distutils.sysconfig and another copy in distutils.ccompiler, with some
329 parts of distutils calling one and others using the other.
330 Complete the revert back to only having one in distutils.sysconfig as
331 is the case in 3.x.
332
Ned Deily0d0ea482012-02-10 12:59:06 +0100333- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
334 Distutils-based packages with C extension modules may fail because
335 Apple has removed gcc-4.2, the version used to build python.org
336 64-bit/32-bit Pythons. If the user does not explicitly override
337 the default C compiler by setting the CC environment variable,
338 Distutils will now attempt to compile extension modules with clang
339 if gcc-4.2 is required but not found. Also as a convenience, if
340 the user does explicitly set CC, substitute its value as the default
341 compiler in the Distutils LDSHARED configuration variable for OS X.
342 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
343 SDK, neither of which are available in Xcode 4. This change does not
344 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700617- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
618 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
619 interpreter process. This could cause failures in non-Distutils subprocesses
620 and was unreliable since tests or user programs could modify the interpreter
621 environment after Distutils set it. Instead, have Distutils set the the
622 deployment target only in the environment of each build subprocess. It is
623 still possible to globally override the default by setting
624 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
625 greater or equal to the default value, the value with which the interpreter
626 was built.

656 the ticker doesn't have to wind down to zero from the old starting point
657 before the new interval takes effect. And if the user increases the
658 interval, it makes sure the new limit takes effect right away rather have an
659 early task switch before recognizing the new interval.

1604 This prevents user-created self-referencing ordered dictionaries from
1605 becoming permanently uncollectable GC garbage. The downside is that

2066
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002067- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2068 start byte and the continuation byte(s) are now considered invalid, instead
2069 of the number of bytes specified by the start byte.
2070 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2071 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2072 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2073 Previous versions returned a single u'\ufffd'.
2074
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002075- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00002076 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2077 arises from the "Overriding __eq__ blocks inheritance ..." warning
2078 when turned into an exception: in this case the exception simply
2079 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002080
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002081- Issue #8748: Fix two issues with comparisons between complex and integer
2082 objects. (1) The comparison could incorrectly return True in some cases
2083 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2084 (2) The comparison raised an OverflowError for large integers, leading
2085 to unpredictable exceptions when combining integers and complex objects
2086 in sets or dicts.
2087
Mark Dickinson81336372010-05-30 12:12:25 +00002088- Issue #5211: Implicit coercion for the complex type is now completely
2089 removed. (Coercion for arithmetic operations was already removed in 2.7
2090 alpha 4, but coercion for rich comparisons was accidentally left in.)
2091
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002092- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
2093 and error handler, instead of writing to the C stderr file in utf-8
2094
Georg Brandlfee0f442010-05-22 21:26:21 +00002095- Issue #7902: When using explicit relative import syntax, don't try implicit
2096 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00002097
Georg Brandlfee0f442010-05-22 21:26:21 +00002098- Issue #7079: Fix a possible crash when closing a file object while using it
2099 from another thread. Patch by Daniel Stutzbach.

Victor Stinnerb65bd2e2010-06-11 19:22:28 +00002101- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00002102 Window Server again in a framework build on MacOSX 10.5 or earlier.

Georg Brandlfee0f442010-05-22 21:26:21 +00002107- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
2108 of the interpreter to set sys.argv without also modifying sys.path. This
2109 helps fix `CVE-2008-5983

2226 non-float non-integer argument is now converted to an integer (if possible)
2227 using its __int__ method. Previously, only small arguments were treated this
2228 way; larger arguments (those whose __int__ was outside the range of a C long)

2456 changed.
2457
Georg Brandlfee0f442010-05-22 21:26:21 +00002458- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

Georg Brandlfee0f442010-05-22 21:26:21 +00002468- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2469 with a non-empty format string. This is an effort to future-proof user
2470 code. If a derived class does not currently implement __format__ but later
2471 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002472 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002473 Python 3.3 and it will be an error in Python 3.4.

2911 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2912 returning NULL. The macro now returns a statically allocated empty string
2913 instead.

2923 strings,
2924 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2925 numeric strings corresponding to subnormal values,

Antoine Pitroud840e512010-02-04 20:20:18 +00002958- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002959 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002960 Also, raise ValueError rather than TypeError when an unknown TIPC address

Georg Brandlba83f822010-03-14 09:50:54 +00002966 file position when calling `truncate()`. It would previously change the file
2967 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002968 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2969

2971 class used to represent files stored inside an archive. The new
2972 implementation is significantly faster and can be wrapped in a
2973 ``io.BufferedReader`` object for more speedups. It also solves an issue
2974 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002985- Issue #7748: Since unicode values are supported for some metadata options in
2986 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2987 encoded string for them. This ensures that the upload and register commands
2988 send the correct values to PyPI without any error.

3073 These functions and methods now raise TypeError instead. The majority of the
3074 effects of this change are in the extension modules, but some core functions
3075 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3076 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00003259- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3260 decimal string that's guaranteed to round back to x under correct rounding
3261 (with round-half-to-even rounding mode). Previously it gave a string based on
3262 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3263 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3264 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00003266- Issue #7117: On almost all platforms: float-to-string and string-to-float
3267 conversions within Python are now correctly rounded. Places these conversions
3268 occur include: str for floats and complex numbers; the float and complex
3269 constructors; old-style and new-style numeric formatting; serialization and
3270 deserialization of floats and complex numbers using marshal, pickle and json;
3271 parsing of float and imaginary literals in Python code; Decimal-to-float
3272 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003273
Georg Brandlba83f822010-03-14 09:50:54 +00003274 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3275 providing correctly-rounded strtod and dtoa C functions. This code is
3276 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3277 the C compiler. There may be a small number of platforms on which correct
3278 operation of this code cannot be guaranteed, so the code is not used: notably,
3279 this applies to platforms where the C double format is not IEEE 754 binary64,
3280 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3281 and Python's configure script is unable to determine how to change the FPU
3282 precision. On these platforms conversions use the platform strtod and dtoa,
3283 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003285- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3286 uses the correctly-rounded string <-> float conversions described above (when
3287 available), and so produces correctly rounded results that will display nicely
3288 under the float repr. There are two related small changes: (1) round now
3289 accepts any class with an ``__index__()`` method for its second argument (but
3290 no longer accepts floats for the second argument), and (2) an excessively
3291 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3292 raises an exception.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005075- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

5077 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5078 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00005176 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5177 for catch_warnings() also led to an improvement in the raising of a
5178 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005244What's New in Python 2.6 beta 3?
5245================================
5246
Barry Warsaw07a4a382008-08-21 01:15:08 +00005247*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005248
5249Core and Builtins
5250-----------------
5251
Guido van Rossumf8402962008-08-20 15:01:50 +00005252- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5253 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5254 extensions do not automatically benefit from the class attribute
5255 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5256 to their tp_flags field if they care. This is a backwards
5257 compatibility feature; in 3.0, all types will use the cache by
5258 default.
5259
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005260- Keyword arguments can now follow starred arguments. (``f(a, *args,
5261 keyword=23)`` is now valid syntax.)
5262
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005263- ctypes function pointers that are COM methods have a boolean True
5264 value again.
5265
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005266- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5267 by denying s# to parse objects that have a releasebuffer procedure,
5268 and introducing s*.
5269
Georg Brandl1e13ea92008-08-11 09:07:59 +00005270- Issue #3537: Fix an assertion failure when an empty but presized dict
5271 object was stored in the freelist.
5272
Mark Dickinsonb6467572008-08-04 21:30:09 +00005273- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5274 ValueError consistently across platforms.
5275
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005276- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5277 (64bit Unix, for example), unichr() would truncate its argument and return
5278 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5279
Neal Norwitze7d8be82008-07-31 17:17:14 +00005280- Apply security patches from Apple.
5281
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005282- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5283 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5284
Antoine Pitrou92f82162008-07-25 22:22:08 +00005285- Issue #1819: function calls with several named parameters are now on
5286 average 35% faster (as measured by pybench).
5287
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005288- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5289 the python debugger steps into a class statement: the free variables (local
5290 variables defined in an outer scope) would be deleted from the outer scope.
5291
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005292- Issue #2620: Overflow checking when allocating or reallocating memory
5293 was not always being done properly in some python types and extension
5294 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5295 all been updated to perform better checks and places in the code that
5296 would previously leak memory on the error path when such an allocation
5297 failed have been fixed.

5300-------
5301
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005302- Issue #3612: Added some missing basic types in ctypes.wintypes.
5303
Benjamin Petersone977ad42008-08-20 01:42:01 +00005304- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5305 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5306
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005307- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5308 version reported by these tools does not necessarily follow the python
5309 version numbering scheme, so the module is less strict when parsing it.
5310
Nick Coghlanf70385a2008-08-18 12:42:46 +00005311- Issue #2235: Added Py3k warnings for types which will become unhashable
5312 under the stricter __hash__ inheritance rules in 3.0. Several types
5313 which did not meet the rules for hash invariants and were already
5314 unhashable in 3.0 have now been explicitly flagged as unhashable in
5315 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5316 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5317
Brett Cannon88f801d2008-08-18 00:46:22 +00005318- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5319 imported into the module but exposed as part of the module's API.
5320
Brett Cannon7b96f072008-08-18 00:41:11 +00005321- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5322
Brett Cannon46225e72008-08-18 00:36:52 +00005323- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005325- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5326
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005327- Issue #3575: Incremental decoder's decode function now takes bytearray
5328 by using 's*' instead of 't#'.
5329
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005330- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005331 fails unicode conversion on 2nd parameter. (windows only)
5332
Georg Brandl222e2082010-08-01 22:27:39 +00005333- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005334 in a redirect.
5335
Brett Cannonabe423e2008-08-16 21:47:07 +00005336- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005337 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005338
Facundo Batistaeb90b782008-08-16 14:44:07 +00005339- Issue #2776: fixed small issue when handling an URL with double slash
5340 after a 302 response in the case of not going through a proxy.
5341
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005342- Issue #2676: in the email package, content-type parsing was hanging on
5343 pathological input because of quadratic or exponential behaviour of a
5344 regular expression.
5345
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005346- Issue #3476: binary buffered reading through the new "io" library is now
5347 thread-safe.
5348
Brett Cannonbf3157b2008-08-14 05:00:03 +00005349- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5350 since mimetools itself is deprecated. Because modules are cached, all
5351 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5352
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005353- Issue #3134: shutil referenced undefined WindowsError symbol.
5354
Robert Schuppenies14646332008-08-10 11:01:53 +00005355- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5356 menu entries were not deleted.
5357
Brett Cannon83e81842008-08-09 23:30:55 +00005358- Copied the implementation of reduce() to _functools.reduce() to have a
5359 version that did not raise a DeprecationWarning under -3.
5360
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005361- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5362 a MemoryError rather than silently stop the iteration.
5363
Guido van Rossum59ce9012008-08-09 14:55:34 +00005364- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5365 to _sre.compile() will now be rejected. This should not affect anybody
5366 since the re.compile() function never generates invalid re-bytecode.
5367
Skip Montanaroa032bf42008-08-08 22:52:51 +00005368- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5369 upon first access it can be automatically initialized from the csv file if
5370 it wasn't initialized during instantiation.
5371
Brett Cannon3aa2a492008-08-06 22:28:09 +00005372- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5373 the reload() built-in has been removed.
5374
Brett Cannon7e30b672008-08-04 21:52:25 +00005375- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005376 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005377 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
5378 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
5379 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5380 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5381 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005382

Antoine Pitroude781a42008-08-09 12:43:23 +00005387 asking for a specific length. This problem only affected files opened

5444-----------------
5445
Georg Brandl3e483f62008-07-16 22:57:41 +00005446- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5447 its methods now allow for items objects that can be converted to
5448 an integer using operator.index().
5449
Mark Dickinson64b7e502008-07-16 09:40:03 +00005450- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5451 produced a ValueError instead of giving the correct float.
5452
Eric Smitha5fa5a22008-07-16 00:11:49 +00005453- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5454 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5455
Mark Dickinson7103aa42008-07-15 19:08:33 +00005456- Issue #3008: the float type has a new instance method 'float.hex'
5457 and a new class method 'float.fromhex' to convert floating-point
5458 numbers to and from hexadecimal strings, respectively.
5459
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005460- Issue #2235: __hash__ is once again inherited by default. To allow
5461 collections.Hashable to remain meaningful in the presence of the
5462 default hash implementation (object.__hash__), it is now possible
5463 to explicit block inheritance of hash by setting __hash__=None at
5464 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5465 level.
5466
Nick Coghlanb028f502008-07-13 14:52:36 +00005467- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5468 the parent module cannot be found while performing an absolute import.
5469 This means that an incorrectly defined __package__ attribute will
5470 now only prevent relative imports in that module rather than causing
5471 all imports from that module to fail.
5472
Nick Coghlan14ff9942008-07-08 14:21:42 +00005473- Issue #2517: Allow unicode messages in Exceptions again by correctly

5483 another thread's dictionary.
5484
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005485- Issue #3004: Minor change to slice.indices(): the start and stop
5486 arguments are now treated identically, making the behaviour easier
5487 to describe and understand. For example, slice(None, -10,
5488 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5489 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5490 10, -1).
5491
Georg Brandl278fc502008-07-19 12:46:12 +00005492- Issue #3219: Calling a function with repeated keyword arguments,
5493 f(a=2, a=23), would not cause a syntax error. This was a regression
5494 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005532- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5533 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005534 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005535 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005551- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00006006- Issue #1631171: Re-implement the 'warnings' module in C (the
6007 original Python code has been kept as backup). This will allow for
6008 using the 'warning's machinery in such places as the parser where
6009 use of pure Python code is not possible. Both the ``showarning()``
6010 and ``formatwarning()`` gain an optional 'line' argument which is
6011 not called by default for backwards-compatibility reasons. Setting
6012 ``warnings.showwarning()`` to an implementation that lacks support
6013 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006055- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006056 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006076- Issue #2550: The approach used by client/server code for obtaining
6077 ports to listen on in network-oriented tests has been refined in an
6078 effort to facilitate running multiple instances of the entire
6079 regression test suite in parallel without issue.
6080 test_support.bind_port() has been fixed such that it will always
6081 return a unique port -- which wasn't always the case with the
6082 previous implementation, especially if socket options had been set
6083 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6084 new implementation of bind_port() will actually raise an exception
6085 if it is passed an AF_INET/SOCK_STREAM socket with either the
6086 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6087 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6088 the socket it's been passed. This currently only applies to
6089 Windows. This option prevents any other sockets from binding to the
6090 host/port we've bound to, thus removing the possibility of the
6091 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6092 when a second SOCK_STREAM socket binds and accepts to a host/port
6093 that's already been bound by another socket. The optional preferred
6094 port parameter to bind_port() has been removed. Under no
6095 circumstances should tests be hard coding ports!
6096
6097 test_support.find_unused_port() has also been introduced, which will
6098 pass a temporary socket object to bind_port() in order to obtain an
6099 unused port. The temporary socket object is then closed and
6100 deleted, and the port is returned. This method should only be used
6101 for obtaining an unused port in order to pass to an external program
6102 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6103 a parameter to a server-oriented class that doesn't give you direct
6104 access to the underlying socket used.
6105
6106 Finally, test_support.HOST has been introduced, which should be used
6107 for the host argument of any relevant socket calls (i.e. bind and
6108 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006109
6110 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006111 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006112 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6113 test_asynchat and test_socket_ssl.
6114
Georg Brandl3ee81df2008-05-17 18:14:43 +00006115 It is now possible for multiple instances of the regression test
6116 suite to run in parallel without issue.

6384
Fred Drakea8ee94b2008-03-01 02:45:07 +00006385- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006386 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006387
Georg Brandlad61bc82008-02-23 15:11:18 +00006388- Issue #2067: file.__exit__() now calls subclasses' close() method.
6389
6390- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006391
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006392- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006393 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006394
Eric Smitha73fbe72008-02-23 03:09:44 +00006395- Added the future_builtins module, which contains hex() and oct().
6396 These are the PEP 3127 version of these functions, designed to be
6397 compatible with the hex() and oct() builtins from Python 3.0. They
6398 differ slightly in their output formats from the existing, unchanged
6399 Python 2.6 builtins. The expected usage of the future_builtins
6400 module is:
6401 from future_builtins import hex, oct
6402
Eric Smith7ef40bf2008-02-20 23:34:22 +00006403- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6404 exponents for exponents with absolute value < 100. Follows C99
6405 standard. This is a change on Windows, which would use 3 digits.
6406 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6407 so that any alterations it does to the resulting string will be
6408 available in stringlib/formatter.h (for float.__format__).
6409
Eric Smith5a3c1352008-02-19 13:21:56 +00006410- Implemented PEP 3101, Advanced String Formatting. This adds a new
6411 builtin format(); a format() method for str and unicode; a
6412 __format__() method to object, str, unicode, int, long, float, and
6413 datetime; the class string.Formatter; and the C API
6414 PyObject_Format().
6415
Georg Brandl3ee81df2008-05-17 18:14:43 +00006416- Fixed several potential crashes, all caused by specially crafted
6417 __del__ methods exploiting objects in temporarily inconsistent
6418 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006419
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006420- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006421 prevent a possible crash: an Abstract Base Class would try to access
6422 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006423

Georg Brandl3ee81df2008-05-17 18:14:43 +00006427- Clear all free lists during a gc.collect() of the highest generation
6428 in order to allow pymalloc to free more arenas. Python may give back
6429 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006430
Georg Brandl3ee81df2008-05-17 18:14:43 +00006431- Issue #2045: Fix an infinite recursion triggered when printing a
6432 subclass of collections.defaultdict, if its default_factory is set
6433 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006434
Christian Heimesf75dbef2008-02-08 00:11:31 +00006435- Fixed a minor memory leak in dictobject.c. The content of the free
6436 list was not freed on interpreter shutdown.
6437
Georg Brandl21e99f42010-03-07 15:23:59 +00006438- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006439 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006440
Georg Brandl3ee81df2008-05-17 18:14:43 +00006441- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6442 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006443 to compact the internal free lists of pre-allocted ints and floats.
6444
Georg Brandl3ee81df2008-05-17 18:14:43 +00006445- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6446 calls. Python expected the return type int but the fork familie
6447 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006448
Georg Brandl3ee81df2008-05-17 18:14:43 +00006449- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00006461- Patch #1473257: generator objects gain a gi_code attribute. This is
6462 the same object as the func_code attribute of the function that
6463 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006464
Georg Brandl3ee81df2008-05-17 18:14:43 +00006465- Issue #1920: "while 0" statements were completely removed by the
6466 compiler, even in the presence of an "else" clause, which is
6467 supposed to be run when the condition is false. Now the compiler
6468 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006469
Guido van Rossumeead05f2008-01-24 18:21:02 +00006470- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006474- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006475 suppressed while an extension is loaded by calling SetErrorMode in
6476 dynload_win.c. The error is still reported properly.
6477
Georg Brandl3ee81df2008-05-17 18:14:43 +00006478- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006479 several extension methods and modules do not work without unicode
6480 support.
6481
Georg Brandl26543b12008-01-21 18:36:51 +00006482- Issue #1882: when compiling code from a string, encoding cookies in the
6483 second line of code were not always recognized correctly.
6484
Georg Brandl14404b62008-01-19 19:27:05 +00006485- Issue #1679: "0x" was taken as a valid integer literal.
6486
Georg Brandl6caad7d2008-01-26 14:19:22 +00006487- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006488 added.
6489
Christian Heimesc94e2b52008-01-14 04:13:37 +00006490- sys.float_info / PyFloat_GetInfo: The floating point information
6491 object was converted from a dict to a specialized structseq object.
6492
Georg Brandl3ee81df2008-05-17 18:14:43 +00006493- Patch #1816: Added sys.flags structseq. It exposes the status of
6494 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006495
Georg Brandl3ee81df2008-05-17 18:14:43 +00006496- Objects/structseq.c: Implemented new structseq representation. The
6497 patch makes structseqs (e.g. the return value of os.stat) more
6498 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006499
Georg Brandl3ee81df2008-05-17 18:14:43 +00006500- Patch #1700288: added a type attribute cache that caches method
6501 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006502
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006503- Bug #1776: __import__() no longer accepts filenames on any platform.
6504 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006505
Georg Brandlaed6c662008-01-07 17:25:53 +00006506- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6507
Georg Brandl3ee81df2008-05-17 18:14:43 +00006508- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6509 envvar and sys.dont_write_bytecode attribute. All these can be set
6510 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006511
Georg Brandl3ee81df2008-05-17 18:14:43 +00006512- Improve some exception messages when Windows fails to load an
6513 extension module. Now we get for example '%1 is not a valid Win32
6514 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006515
Georg Brandl3ee81df2008-05-17 18:14:43 +00006516- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006518- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6519 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006520
Christian Heimes0a8143f2007-12-18 23:22:54 +00006521- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006522 and INF. float("nan"), float("inf") and float("-inf") now work on
6523 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006524
Georg Brandl3ee81df2008-05-17 18:14:43 +00006525- Compiler now generates simpler and faster code for dictionary
6526 literals. The oparg for BUILD_MAP now indicates an estimated
6527 dictionary size. There is a new opcode, STORE_MAP, for adding
6528 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006532- Issue #1620: New property decorator syntax was modifying the
6533 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006534
Georg Brandl3ee81df2008-05-17 18:14:43 +00006535- Issue #1538: Avoid copying string in split/rsplit if the split char
6536 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006537
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006538- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006539 SystemError.
6540
Nick Coghlanef01d822007-12-03 12:55:17 +00006541- PEP 366: Allow explicit relative imports when executing modules
6542 inside packages with the -m switch via a new module level
6543 __package__ attribute.
6544
Georg Brandl3ee81df2008-05-17 18:14:43 +00006545- Issue #1402: Fix a crash on exit, when another thread is still
6546 running, and if the deallocation of its frames somehow calls the
6547 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006548

6553
Georg Brandl3ee81df2008-05-17 18:14:43 +00006554- Issue #1460: The utf-7 incremental decoder did not accept truncated
6555 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006556
Georg Brandl3ee81df2008-05-17 18:14:43 +00006557- Patch #1739468: Directories and zipfiles containing a __main__.py
6558 file can now be directly executed by passing their name to the
6559 interpreter. The directory/zipfile is automatically inserted as the
6560 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006561
Georg Brandl3ee81df2008-05-17 18:14:43 +00006562- Issue #1265: Fix a problem with sys.settrace, if the tracing
6563 function uses a generator expression when at the same time the
6564 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006565
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006566- sets and frozensets now have an isdisjoint() method.
6567
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006568- optimize the performance of builtin.sum().
6569
Neal Norwitz44f326e2007-10-05 05:29:17 +00006570- Fix warnings found by the new version of the Coverity checker.
6571
Georg Brandl21e99f42010-03-07 15:23:59 +00006572- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006573 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6574 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006575
Georg Brandl3ee81df2008-05-17 18:14:43 +00006576- Issue #1686386: Tuple's tp_repr did not take into account the
6577 possibility of having a self-referential tuple, which is possible
6578 from C code. Nor did object's tp_str consider that a type's tp_str
6579 could do something that could lead to an inifinite recursion.
6580 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6581 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006582
Georg Brandl3ee81df2008-05-17 18:14:43 +00006583- Issue #1164: It was possible to trigger deadlock when using the
6584 'print' statement to write to a file since the GIL was not released
6585 as needed. Now PyObject_Print() does the right thing along with
6586 various tp_print implementations of the built-in types and those in
6587 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006588
Georg Brandl3ee81df2008-05-17 18:14:43 +00006589- Issue #1147: Exceptions were directly allowing string exceptions in
6590 their throw() method even though string exceptions no longer
6591 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006592
Georg Brandl3ee81df2008-05-17 18:14:43 +00006593- Issue #1096: Prevent a segfault from getting the repr of a very
6594 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006595
Brett Cannon1e534b52007-09-07 04:18:30 +00006596- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006597 PyObject_Call() never calling back out to Python code to trigger
6598 recursion depth updates/checks. Required the creation of a static
6599 RuntimeError instance in case normalizing an exception put the
6600 recursion check value past its limit. Fixes crashers
6601 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006602
Georg Brandl3ee81df2008-05-17 18:14:43 +00006603- Patch #1031213: Decode source line in SyntaxErrors back to its
6604 original source encoding.

6607 with %G.
6608
Georg Brandl3ee81df2008-05-17 18:14:43 +00006609- Prevent expandtabs() on string and unicode objects from causing a
6610 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006611

Georg Brandla5ea6892007-06-01 11:33:33 +00006615
Neal Norwitz0ac60192007-05-27 04:08:54 +00006616- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006617 __*__ attributes. (Some already existed, e.g., __doc__ and
6618 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006619
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006620- Add -3 option to the interpreter to warn about features that are
6621 deprecated and will be changed/removed in Python 3.0.
6622
Georg Brandl2134e752007-05-21 20:34:16 +00006623- Patch #1686487: you can now pass any mapping after '**' in function
6624 calls.
6625
Collin Winter62903052007-05-18 23:11:24 +00006626- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006627 "except E as target:". This is to provide forwards compatibility
6628 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006629
Brett Cannon229cee22007-05-05 01:34:02 +00006630- Deprecate BaseException.message as per PEP 352.
6631
Georg Brandl3ee81df2008-05-17 18:14:43 +00006632- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006633 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006634
Vinay Sajip8549ce32007-05-06 17:53:37 +00006635- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006636 setting a plain string, ie don't expand to single letter identifiers.
6637
Raymond Hettinger13936692007-04-11 18:40:58 +00006638- Request #1191699: Slices can now be pickled.
6639
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006640- Request #1193128: str.translate() now allows a None argument for
6641 translations that only remove characters without re-mapping the
6642 remaining characters.
6643
Georg Brandl5cb76c12007-03-21 09:00:39 +00006644- Patch #1682205: a TypeError while unpacking an iterable is no longer
6645 masked by a generic one with the message "unpack non-sequence".
6646
Neal Norwitzaa754b72007-03-21 06:39:48 +00006647- Remove unused file Python/fmod.c.
6648
Guido van Rossum143b5642007-03-23 04:58:42 +00006649- Bug #1683368: The object.__init__() and object.__new__() methods are
6650 now stricter in rejecting excess arguments. The only time when
6651 either allows excess arguments is when it is not overridden and the
6652 other one is. For backwards compatibility, when both are
6653 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006654 warning later). Also, type.__init__() insists on the same signature
6655 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006656
Georg Brandl3ee81df2008-05-17 18:14:43 +00006657- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6658 object to complex using its __complex__() method before falling back
6659 to the __float__() method. Therefore, the functions in the cmath
6660 module now can operate on objects that define a __complex__()
6661 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006662
Georg Brandl3ee81df2008-05-17 18:14:43 +00006663- Patch #1623563: allow __class__ assignment for classes with
6664 __slots__. The old and the new class are still required to have the
6665 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006666
Georg Brandl3ee81df2008-05-17 18:14:43 +00006667- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00006670- Patch #1462488: Python no longer segfaults when
6671 ``object.__reduce_ex__()`` is called with an object that is faking
6672 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006673
Georg Brandl3ee81df2008-05-17 18:14:43 +00006674- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00006677- Patch #1444529: the builtin compile() now accepts keyword arguments.
6678
Georg Brandl7b9c5552007-03-12 14:30:05 +00006679- Bug #1678647: write a newline after printing an exception in any
6680 case, even when converting the value to a string failed.
6681
Georg Brandl871f1bc2007-03-12 13:17:36 +00006682- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006683 its argument, if it exists. If not, it will work like before. This
6684 allows customizing the output of dir() in the presence of a
6685 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006686
Collin Winter276887b2007-03-12 16:11:39 +00006687- Patch #922167: Python no longer segfaults when faced with infinitely
6688 self-recursive reload() calls (as reported by bug #742342).
6689
Georg Brandl3ee81df2008-05-17 18:14:43 +00006690- Patch #1675981: remove unreachable code from ``type.__new__()``
6691 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006693- Patch #1491866: change the complex() constructor to allow
6694 parthensized forms. This means complex(repr(x)) now works instead of
6695 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006696
Georg Brandlaa2321b2007-03-07 00:40:28 +00006697- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006698 makes the filenames the warning module prints much more sensible
6699 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006700
Georg Brandl49aafc92007-03-07 00:34:46 +00006701- Variant of patch #697613: don't exit the interpreter on a SystemExit
6702 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006703 variable is given, but break into the interactive interpreter just
6704 like on other exceptions or normal program exit.

Georg Brandlfb4b3b72007-04-24 15:27:13 +00007204- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
7205 (as opposed to the command line) will now write file names ending in
7206 ".cpp" too.
7207
Facundo Batistad918a652007-04-24 13:54:38 +00007208- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007209 the client's request was successfully received, understood, and
7210 accepted. Now in these cases no error is raised in urllib (issue
7211 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00007212

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007219- Added a timeout parameter to the constructor of other protocols
7220 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7221 work started with create_connection() and timeout in httplib, and
7222 closes patch #723312.
7223
Vinay Sajip8549ce32007-05-06 17:53:37 +00007224- Patch #1676823: Added create_connection() to socket.py, which may be
7225 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007226 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007227
Martin v. Löwis0af33882007-03-23 13:27:15 +00007228- Bug #978833: Revert r50844, as it broke _socketobject.dup.

7248
Georg Brandlf66b6032007-03-14 08:27:52 +00007249- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007250 AttributeError instead of an IOError when the server's response
7251 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007252
Georg Brandl3ee81df2008-05-17 18:14:43 +00007253- Patch #957650: "%var%" environment variable references are now
7254 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00007256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007257- Patch #1429539: pdb now correctly initializes the __main__ module
7258 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007259 correctly now.
7260
Georg Brandlbad6f192007-03-13 21:32:56 +00007261- The nonobvious commands.getstatus() function is now deprecated.

7267
Georg Brandl3ee81df2008-05-17 18:14:43 +00007268- Patch #1530482: add pydoc.render_doc() which returns the
7269 documentation for a thing instead of paging it to stdout, which
7270 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00007271
Georg Brandl3ee81df2008-05-17 18:14:43 +00007272- Patch #1533909: the timeit module now accepts callables in addition

7278 parameter which can be set to False to prevent the default
7279 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00007280
Georg Brandl9e6b4702007-03-13 18:15:41 +00007281- Patch #1581073: add a flag to textwrap that prevents the dropping of
7282 whitespace while wrapping.
7283
Georg Brandl92a6bae2007-03-13 17:43:32 +00007284- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007285 are set for invalid interpolation sequences that would lead to
7286 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007287

7329 returned string up to the first NUL character.

7340
Georg Brandl3ee81df2008-05-17 18:14:43 +00007341- unittest now verifies more of its assumptions. In particular,
7342 TestCase and TestSuite subclasses (not instances) are no longer
7343 accepted in TestSuite.addTest(). This should cause no
7344 incompatibility since it never made sense with ordinary subclasses
7345 -- the failure just occurred later, with a more cumbersome
7346 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00007347

7355 given a unicode argument and os.listdir() returns unicode filenames.
7356
Georg Brandl3ee81df2008-05-17 18:14:43 +00007357- Patch #1673619: setup.py identifies extension modules it doesn't
7358 know how to build and those it knows how to build but that fail to
7359 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007735 time so that opening a database previously created with the DB_DUP
7736 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7737 opens. Specifically: dictionary assignment to a DB object will
7738 replace all values for a given key when the database allows
7739 duplicate values. DB users should use DB.put(k, v) when they want
7740 to store duplicates; not DB[k] = v.

7747 characters with ASCII value less than 32. Also, it correctly quotes
7748 dots only if they occur on a single line, as opposed to the previous
7749 behavior of quoting dots if they are the second character of any
7750 line.
