290 * Try to avoid building Python or extension modules with problematic

293 check for ppc compiler support and automatically remove ppc and
294 ppc64 archs when not available.

296 extension module builds now revert to using installed headers
297 and libs if the SDK used to build the interpreter is not

Antoine Pitroue0e27352011-12-15 14:31:28 +01001164- Fix OSError.__init__ and OSError.__new__ so that each of them can be
1165 overriden and take additional arguments (followup to issue #12555).
1166
Antoine Pitrou2e872082011-12-15 14:15:31 +01001167- Fix the fix for issue #12149: it was incorrect, although it had the side

Antoine Pitrou5418ee02011-11-15 01:42:21 +01001213- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
1214 already accepts them).
1215
Antoine Pitrou9a812cb2011-11-15 00:00:12 +01001216- Issue #13389: Full garbage collection passes now clear the freelists for

1660 Distutils-based packages with C extension modules may fail because
1661 Apple has removed gcc-4.2, the version used to build python.org
1662 64-bit/32-bit Pythons. If the user does not explicitly override
1663 the default C compiler by setting the CC environment variable,
1664 Distutils will now attempt to compile extension modules with clang
1665 if gcc-4.2 is required but not found. Also as a convenience, if
1666 the user does explicitly set CC, substitute its value as the default
1667 compiler in the Distutils LDSHARED configuration variable for OS X.
1668 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1669 SDK, neither of which are available in Xcode 4. This change does not
1670 attempt to override settings to support their use with Xcode 4.)

Éric Araujo0cdd4452011-07-28 00:28:28 +02002248- Issue #10968: Remove indirection in threading. The public names (Thread,
2249 Condition, etc.) used to be factory functions returning instances of hidden
2250 classes (_Thread, _Condition, etc.), because (if Guido recalls correctly) this

2252 inherit from Thread and other classes, without having to import the private
2253 underscored names like multiprocessing did.

2293 to get channel binding data for the current SSL session (only the

2345
Victor Stinner7f53a502011-07-05 22:00:25 +02002346- Issue #12459: time.sleep() now raises a ValueError if the sleep length is
2347 negative, instead of an infinite sleep on Windows or raising an IOError on
2348 Linux for example, to have the same behaviour on all platforms.

2384 UTF-8 instead of the locale encoding if the encoding is not specified. It now
2385 also opens XML files for the parser in binary mode instead of the text mode

2396
Ned Deily657b2de2011-06-28 19:51:30 -07002397- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2398 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2399 interpreter process. This could cause failures in non-Distutils subprocesses
2400 and was unreliable since tests or user programs could modify the interpreter
2401 environment after Distutils set it. Instead, have Distutils set the the
2402 deployment target only in the environment of each build subprocess. It is
2403 still possible to globally override the default by setting
2404 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2405 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -07002406 was built. Also, implement the same handling in packaging.

Georg Brandld2f38572011-01-30 08:37:19 +00003602 that for incoming headers which makes this behaviour now consistent in
3603 both incoming and outgoing direction.

Georg Brandl255abdd2011-01-16 14:17:26 +00003700 continuation line in the formatted value has no leading white space and looks
3701 like a header. Since Generator uses Header to format all headers, this check
3702 is made for all headers in any serialized message at serialization time. This
3703 provides protection against header injection attacks.

Georg Brandl255abdd2011-01-16 14:17:26 +00003713 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00003714
Éric Araujof0ab5d62011-05-29 03:43:59 +02003715- email.header.Header was incorrectly encoding folding whitespace when

3717 folding whitespace. It now uses the continuation_ws, as it does for
3718 continuation lines that it creates itself.

3721 time.asctime(), time.ctime() and time.strftime() functions will now format

3723 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
3724 supported by the OS. With Visual Studio or on Solaris, the year is limited to
3725 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00004709- Issue #10068: Global objects which have reference cycles with their module's
4710 dict are now cleared again. This causes issue #7140 to appear again.
4711
Victor Stinner257d38f2010-10-09 10:12:11 +00004712- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()

Georg Brandl27a28582010-10-10 09:49:21 +00004715- ast.literal_eval() can now handle negative numbers. It is also a little more
4716 liberal in what it accepts without compromising the safety of the evaluation.
4717 For example, 3j+4 and 3+4+5 are both accepted.

Victor Stinner5593d8a2010-10-02 11:11:27 +00004724- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00004725 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00004739- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00004740 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

4743
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00004744- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
4745 threads are still running. Instead, reinitialize the GIL on a second call to
4746 Py_Initialize().
4747
Georg Brandl27a28582010-10-10 09:49:21 +00004748- All SyntaxErrors now have a column offset and therefore a caret when the error
4749 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00004750
Brett Cannonbc2eff32010-09-19 21:39:02 +00004751- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
4752 module that was imported, but instead gets the module from sys.modules.
4753
Nick Coghlan37ee8502010-12-03 14:26:13 +00004754- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00004757- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4758 with a non-empty format string. This is an effort to future-proof user
4759 code. If a derived class does not currently implement __format__ but later
4760 adds its own __format__, it would most likely break user code that had
4761 supplied a format string. This will be changed to a DeprecationWaring in
4762 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00004763
Antoine Pitrou1df15362010-09-13 14:16:46 +00004764- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
4765 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
4766 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
4767
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00004768- Issue #9210: Configure option --with-wctype-functions was removed. Using the
4769 functions from the libc caused the methods .upper() and lower() to become
4770 locale aware and created subtly wrong results.
4771
Georg Brandl27a28582010-10-10 09:49:21 +00004772- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
4773 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00004774
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00004775- Issue #4617: Previously it was illegal to delete a name from the local
4776 namespace if it occurs as a free variable in a nested block. This limitation
4777 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
4778
Georg Brandl27a28582010-10-10 09:49:21 +00004779- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
4780 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
4781 Also, the "backslashreplace" error handler now joins surrogate pairs into a
4782 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00004783
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00004784- Issue #9757: memoryview objects get a release() method to release the
4785 underlying buffer (previously this was only done when deallocating the
4786 memoryview), and gain support for the context management protocol.
4787
Antoine Pitrou079ce542010-09-08 12:37:10 +00004788- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
4789 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00004805- Issue #4661: email can now parse bytes input and generate either converted

Antoine Pitrou59fdd672010-10-08 10:37:08 +00004808- Issue #1589: Add ssl.match_hostname(), to help implement server identity

4816
Éric Araujoef777bd2010-10-05 00:04:20 +00004817- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00004818 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00004819 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00004820 replacement for old handle_accept() and avoids the user to call accept()
4821 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00004845 retry the select() loop instead of bailing out. This is because select() can
4846 incorrectly report a socket as ready for reading (for example, if it received
4847 some data with an invalid checksum).

Antoine Pitrou98b46702010-09-18 22:59:00 +00004893- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00004894 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00004927- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00004928 it possible for the user to create self-referencing ordered dictionaries which
4929 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00004930 approach of using weakref proxies so that reference cycles never get created
4931 in the first place.

4939 sys.setfilesystemencoding() creates inconsistencies because it is unable to
4940 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00004952- Issue #9707: Rewritten reference implementation of threading.local which is
4953 friendlier towards reference cycles. This change is not normally visible

Antoine Pitrou783eea72010-09-07 22:06:17 +00004955
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00004956- Issue #6394: os.getppid() is now supported on Windows. Note that it will
4957 still return the id of the parent process after it has exited. This process
4958 id may even have been reused by another unrelated process.
4959
Georg Brandl27a28582010-10-10 09:49:21 +00004960- Issue #9792: In case of connection failure, socket.create_connection() would
4961 swallow the exception and raise a new one, making it impossible to fetch the
4962 original errno, or to filter timeout errors. Now the original error is
4963 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00004964
Georg Brandl27a28582010-10-10 09:49:21 +00004965- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
4966 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
4967 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00004969- Updates to the random module:
4970
Georg Brandl27a28582010-10-10 09:49:21 +00004971 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00004974 * Update the seed() method to use all of the bits in a string instead of just
4975 the hash value. This makes better use of the seed value and assures the
4976 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00004978 * Improved the random()-->integer algorithm used in choice(), shuffle(),
4979 sample(), randrange(), and randint(). Formerly, it used int(n*random())
4980 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00004981
4982 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00005001- hashlib has two new constant attributes: algorithms_guaranteed and
5002 algorithms_avaiable that respectively list the names of hash algorithms
5003 guaranteed to exist in all Python implementations and the names of hash
5004 algorithms available in the current process.

Ezio Melotti57221d02010-07-01 07:32:02 +00005516- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00005517 start byte and the continuation byte(s) are now considered invalid, instead of
5518 the number of bytes specified by the start byte. E.g.:
5519 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
5520 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
5521 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
5522 returned a single u'\ufffd'.

5566 TypeError instead of giving a DeprecationWarning when a float is parsed using
5567 the 'L' code (for long long). (All other integer codes already raise

5929 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
5930 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00005931 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00006034- The default size of the re module's compiled regular expression cache has been
6035 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00006036 simply clearing the entire cache on overflow to forgetting the least recently
6037 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00006038 applications that use a lot of regular expressions and limits the impact of
6039 the performance hit anytime the cache is exceeded.

6054 on the original python prototype for the datetime module by Tim Peters with
6055 minor modifications by the PyPy project. The test suite now tests `datetime`
6056 module with and without `_datetime` acceleration using the same test cases.

6284
Victor Stinnerd17f2192010-08-15 09:56:07 +00006285- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00006286 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00006293- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
6294 operation raises multiple signals and more than one of those signals is
6295 trapped, the specification determines the order in which the signals should be
6296 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandl62069d32010-07-31 08:56:11 +00006336- Issue #8524: When creating an SSL socket, the timeout value of the original
6337 socket wasn't retained (instead, a socket with a positive timeout would be
6338 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00006339
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00006340- Issue #5103: SSL handshake would ignore the socket timeout and block
6341 indefinitely if the other end didn't respond.
6342
Georg Brandl62069d32010-07-31 08:56:11 +00006343- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00006448- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
6449 InvalidOperation instead of returning False. (Comparisons involving a quiet
6450 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
6451 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00006453- Issue #2531: Comparison operations between floats and Decimal instances now
6454 return a result based on the numeric values of the operands; previously they
6455 returned an arbitrary result based on the relative ordering of id(float) and

6472 makes Fraction <=> complex comparisons consistent with int <=> complex, float
6473 <=> complex, and complex <=> complex comparisons.

6517 an extension module (_posixsubprocess) so that the fork()+exec() can be done
6518 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00006519
Georg Brandl62069d32010-07-31 08:56:11 +00006520- subprocess.Popen now has restore_signals and start_new_session features. The
6521 default of restore_signals=True is a new behavior compared to earlier Python

6523 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00006524

Georg Brandl62069d32010-07-31 08:56:11 +00006609- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
6610 position when calling `truncate()`. It would previously change the file
6611 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00006612 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
6613
Antoine Pitroua32f9a22010-01-27 21:18:57 +00006614- Issue #7610: Reworked implementation of the internal
Georg Brandl88b95f92012-05-06 11:24:06 +02006615 ``zipfile.ZipExtFile`` class used to represent files stored inside an
Georg Brandl62069d32010-07-31 08:56:11 +00006616 archive. The new implementation is significantly faster and can be wrapped in
Georg Brandl88b95f92012-05-06 11:24:06 +02006617 a ``io.BufferedReader`` object for more speedups. It also solves an
Georg Brandl62069d32010-07-31 08:56:11 +00006618 issue where interleaved calls to `read()` and `readline()` give wrong results.
6619 Patch by Nir Aides.

Senthil Kumaran97f0c6b2009-07-25 04:24:38 +00006953
Brett Cannon69194272009-07-20 04:23:48 +00006954- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00006955 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
6956 PyPycLoader inherit from this class and provide implementations in relation to
6957 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00006958
Brett Cannon64ef00f2009-07-20 03:19:18 +00006959- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
6960 the documentation said it did even though the code in PyLoader relied on the
6961 abstract method required by ResourceLoader.
6962
Georg Brandl62069d32010-07-31 08:56:11 +00006963- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how
6964 to handle a comparison without loss of precision. Also add correct handling
6965 of infinities and nans for comparisons with float.
Mark Dickinson85424c92009-07-18 14:41:42 +00006966

Georg Brandl62069d32010-07-31 08:56:11 +00006969- Issue #6358: The exit status of a command started with os.popen() was reported
6970 differently than it did with python 2.x.
Amaury Forgeot d'Arc97e5f282009-07-11 09:35:13 +00006971
Georg Brandl62069d32010-07-31 08:56:11 +00006972- Issue #6323: The pdb debugger did not exit when running a script with a syntax
6973 error.
Amaury Forgeot d'Arc2de11152009-07-09 23:07:52 +00006974
Gregory P. Smithd06fa472009-07-04 02:46:54 +00006975- Issue #3392: The subprocess communicate() method no longer fails in select()
6976 when file descriptors are large; communicate() now uses poll() when possible.
6977
Antoine Pitrou54923952009-07-01 14:53:06 +00006978- Issue #6369: Fix an RLE decompression bug in the binhex module.

6985 sys.path.
6986
Alexandre Vassalotticf76e1a2009-07-22 03:24:36 +00006987- Issue #6218: io.StringIO and io.BytesIO instances are now picklable.
6988
Georg Brandl62069d32010-07-31 08:56:11 +00006989- The os.get_exec_path() function to return the list of directories that will be
6990 searched for an executable when launching a subprocess was added.
Gregory P. Smithb6e8c7e2010-02-27 07:22:22 +00006991
Gregory P. Smith3fdd9642010-02-28 18:57:46 +00006992- Issue #7481: When a threading.Thread failed to start it would leave the
6993 instance stuck in initial state and present in threading.enumerate().
6994
Georg Brandl62069d32010-07-31 08:56:11 +00006995- Issue #1068268: The subprocess module now handles EINTR in internal os.waitpid
6996 and os.read system calls where appropriate.
Gregory P. Smitha59c59f2010-03-01 00:17:40 +00006997
Gregory P. Smith1a530912010-03-01 04:59:27 +00006998- Issue #6729: Added ctypes.c_ssize_t to represent ssize_t.
6999
Steven Bethard6d265692010-03-02 09:22:57 +00007000- Issue #6247: The argparse module has been added to the standard library.
7001
Georg Brandl62069d32010-07-31 08:56:11 +00007002- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is a socket
7003 option available on FreeBSD 7.1 and newer.
Larry Hastingsf0f37952010-04-02 11:47:10 +00007004

Mark Dickinson12c4bdb2009-09-28 19:21:11 +00007010
Mark Dickinsonfa41e602010-09-28 07:22:27 +00007011- Issue #9959: Tweak formula used for computing math.log of an integer,
7012 making it marginally more accurate for exact powers of 2.
7013
Mark Dickinsoncf28b952010-07-29 21:41:59 +00007014- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
7015
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00007016- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00007017 compared to other unix systems. In particular, os.getgroups() does not reflect
7018 any changes made using os.setgroups() but basicly always returns the same
7019 information as the id command. os.getgroups() can now return more than 16
7020 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00007021
Martin v. Löwisc9e1c7d2010-07-23 12:16:41 +00007022- Issue #6095: Make directory argument to os.listdir optional.
7023
Georg Brandl62069d32010-07-31 08:56:11 +00007024- Issue #9277: Fix bug in struct.pack for bools in standard mode (e.g.,
7025 struct.pack('>?')): if conversion to bool raised an exception then that
7026 exception wasn't properly propagated on machines where char is unsigned.
Mark Dickinsone26660f2010-07-18 07:48:20 +00007027
Georg Brandl62069d32010-07-31 08:56:11 +00007028- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x python when
7029 they contain instances of old-style classes.
Alexander Belopolskyd92f0402010-07-17 22:50:45 +00007030
Georg Brandl62069d32010-07-31 08:56:11 +00007031- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to accompany
7032 existing isinf and isnan functions.
Mark Dickinson8e0c9962010-07-11 17:38:24 +00007033
Georg Brandl62069d32010-07-31 08:56:11 +00007034- Issue #1578269: Implement os.symlink for Windows 6.0+. Patch by Jason
7035 R. Coombs.
Brian Curtind40e6f72010-07-08 21:39:08 +00007036
Benjamin Petersona9800a82010-07-07 19:04:48 +00007037- In struct.pack, correctly propogate exceptions from computing the truth of an
7038 object in the '?' format.
7039
Alexander Belopolskya11d8c02010-07-06 23:19:45 +00007040- Issue #9000: datetime.timezone objects now have eval-friendly repr.
7041
Benjamin Petersonf751bc92010-07-02 13:46:42 +00007042- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
7043 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00007044
Georg Brandl62069d32010-07-31 08:56:11 +00007045- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
7046 Prior to this change, timezone adjustment in utctimetuple() could produce
7047 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
7048 cases.
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00007049
Georg Brandl62069d32010-07-31 08:56:11 +00007050- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
7051 directive. When the ``%z`` directive is present in the format string, an
7052 aware ``datetime`` object is returned with ``tzinfo`` bound to a
7053 ``datetime.timezone`` instance constructed from the parsed offset. If both
7054 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
7055 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00007056
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00007057- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00007058 implementing ``datetime.tzinfo`` interface. Instances of the new class,
7059 ``datetime.timezone``, return fixed name and UTC offset from their
7060 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
7061 returns ``None``. A class attribute, ``utc`` contains an instance
7062 representing the UTC timezone. Original patch by Rafe Kaplan.
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00007063
Georg Brandl62069d32010-07-31 08:56:11 +00007064- Issue #8973: Add __all__ to struct module; this ensures that help(struct)
7065 includes documentation for the struct.Struct class.
Mark Dickinson4b80ef52010-06-12 15:17:02 +00007066
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00007067- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00007068 For example, "1" or "ilib123" are now invalid formats and cause
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00007069 ``struct.error`` to be raised. Patch by Caleb Deveraux.
Alexander Belopolsky177e8532010-06-11 16:04:59 +00007070
Georg Brandl62069d32010-07-31 08:56:11 +00007071- Issue #7384: If the system readline library is linked against ncurses, the
7072 curses module must be linked against ncurses as well. Otherwise it is not safe
7073 to load both the readline and curses modules in an application.
Stefan Kraha3ac44e2010-06-08 14:00:52 +00007074
Georg Brandl62069d32010-07-31 08:56:11 +00007075- Issue #2810: Fix cases where the Windows registry API returns ERROR_MORE_DATA,
7076 requiring a re-try in order to get the complete result.

Georg Brandl62069d32010-07-31 08:56:11 +00007078- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
7079 with an improved 'binary-split' algorithm that uses fewer multiplications and
7080 allows many of the multiplications to be performed using plain C integer
7081 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
7082 arguments.

Mark Dickinson85eacea2010-05-10 16:27:45 +00007084- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
7085 overflow checks in the audioop module.
7086
Mark Dickinson0381e3f2010-05-08 14:35:02 +00007087- Issue #8644: The accuracy of td.total_seconds() has been improved (by
7088 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00007089 the result is now always correctly rounded, and is equivalent to ``td /
7090 timedelta(seconds=1)``.

Georg Brandl62069d32010-07-31 08:56:11 +00007092- Issue #2706: Allow division of a timedelta by another timedelta: timedelta /

7097
Mark Dickinsonc5935772010-04-03 15:54:36 +00007098- Issue #8300: When passing a non-integer argument to struct.pack with any
7099 integer format code, struct.pack first attempts to convert the non-integer
7100 using its __index__ method. If that method is non-existent or raises
7101 TypeError it goes on to try the __int__ method, as described below.
7102
Matthias Klosea8349752010-03-15 13:25:28 +00007103- Issue #8142: Update libffi to the 3.0.9 release.

7171 (Optimization was unintentionally turned on in gcc --with-pydebug builds as a

7681 to be like 'g' but with at least one decimal point and with a
7682 default precision of 12. Previously, the behavior the same but with
7683 a default precision of 6. This more closely matches str(), and
7684 reduces surprises when adding alignment flags to the empty
7685 presentation type. This also affects the new complex.__format__ in
7686 the same way.

7700 received a new method, detach(). detach() disconnects the underlying stream
7701 from the buffer or text IO and returns it.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00007729- Issue #1869 (and many duplicates): make round(x, n) correctly
7730 rounded for a float x, by using the decimal <-> binary conversions
7731 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
7732 consistently agrees with format(x, '.2f').
7733
Benjamin Petersonae937c02009-04-18 20:54:08 +00007734- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

7738
Eric Smith35e84722009-04-16 20:21:28 +00007739- Issue #5515: str.format() type 'n' combined with commas and leading
7740 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00007741
7742- Implement PEP 378, Format Specifier for Thousands Separator, for
7743 floats.
7744
Mark Dickinson3370cce2009-04-17 22:40:53 +00007745- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007746 1e11, not 1e12. This avoids printing 13 significant digits in
7747 situations where only 12 of them are correct. Example problem
7748 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
7749 long time.)
7750
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007751- Issue #1580: On most platforms, use a 'short' float repr: for a
7752 finite float x, repr(x) now outputs a string based on the shortest
7753 sequence of decimal digits that rounds to x. Previous behaviour was
7754 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00007755 Another minor difference is that the new repr switches to
7756 exponential notation at 1e16 instead of the previous 1e17; this
7757 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007758
7759 There's a new sys attribute sys.float_repr_style, which takes
7760 the value 'short' to indicate that we're using short float repr,
7761 and 'legacy' if the short float repr isn't available for one
7762 reason or another.
7763
7764 The float repr change involves incorporating David Gay's 'perfect
7765 rounding' code into the Python core (it's in Python/dtoa.c). As a
7766 secondary consequence, all string-to-float and float-to-string
7767 conversions (including all float formatting operations) will be
7768 correctly rounded on these platforms.
7769
Georg Brandl5f90d792010-08-01 22:31:05 +00007770 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007771 this change does not apply.

7774
Georg Brandlabc38772009-04-12 15:51:51 +00007775- The string.maketrans() function is deprecated; there is a new static method
7776 maketrans() on the bytes and bytearray classes. This removes confusion about
7777 the types string.maketrans() is supposed to work with, and mirrors the
7778 methods available on the str class.

7948 reduce the size of collections and therefore the garbage collection overhead
7949 on long-running programs, depending on their particular use of datatypes.

8018
Lars Gustäbel42e00912009-03-22 20:34:29 +00008019- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
8020 forever on incomplete input. That caused tarfile.open() to hang when used
8021 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
8022 partial bzip2 compressed data.
8023
Mark Dickinson79f52032009-03-17 23:12:51 +00008024- Issue #2110: Add support for thousands separator and 'n' type

8042 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00008043 struct.error instead of returning b'\xff\xff\xff\xff'. The
8044 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
8045 have been removed from the struct module.

8061 used when using str.format() with str, int, and float arguments.
8062
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00008063- Issue #5249: time.strftime returned malformed string when format string
8064 contained non ascii character on windows.
8065
Benjamin Petersonf5b52242009-03-02 23:31:26 +00008066- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
8067 source has already been decoded into str.
8068
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00008069- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
8070 rotating the object pointer by 4 bits to the right.
8071
Mark Dickinson87ec0852009-02-09 17:15:59 +00008072- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
8073 it now forces its argument to double before testing for infinity.
8074
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00008075- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
8076 returns a non-number type.
8077
Benjamin Peterson87618552009-02-08 15:00:52 +00008078- Issue #5182: Removed memoryview.__str__.
8079
Mark Dickinsonc008a172009-02-01 13:59:22 +00008080- Issue #1717: Removed builtin cmp() function, dropped tp_compare
8081 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00008082 the type definition cmpfunc. The tp_compare slot has been renamed
8083 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00008084
Georg Brandl1cdd83c2009-04-05 20:24:29 +00008085- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00008086 were suppressing all exceptions. These include list() and bytearray().
8087
Mark Dickinson1124e712009-01-28 21:25:58 +00008088- Issue #4707: round(x, n) now returns an integer if x is an integer.
8089 Previously it returned a float.
8090
Antoine Pitroub52ec782009-01-25 16:34:23 +00008091- Issue #4753: By enabling a configure option named '--with-computed-gotos'
8092 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
8093 evaluation loop is compiled with a new dispatch mechanism which gives
8094 speedups of up to 20%, depending on the system, on various benchmarks.
8095
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00008096- Issue #4874: Most builtin decoders now reject unicode input.

8102
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00008103- Issue #4838: When a module is deallocated, free the memory backing the
8104 optional module state data.
8105
Mark Dickinson8055afd2009-01-17 10:04:45 +00008106- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008107 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00008108
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00008109- Issue #4935: The overflow checking code in the expandtabs() method common
8110 to str, bytes and bytearray could be optimized away by the compiler, letting
8111 the interpreter segfault instead of raising an error.
8112
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00008113- Issue #3720: Fix a crash when an iterator modifies its class and removes its
8114 __next__ method.
8115
Mark Dickinsone5e298f2009-01-12 20:49:19 +00008116- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
8117 function no longer attempt to call the __long__ slot to convert an object
8118 to an integer. Only the __int__ and __trunc__ slots are examined.
8119
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00008120- Issue #4893: Use NT threading on CE.
8121
Martin v. Löwisec59d042009-01-12 07:59:10 +00008122- Issue #4915: Port sysmodule to Windows CE.
8123
Antoine Pitrouab868312009-01-10 15:40:25 +00008124- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
8125 common cases are optimized thanks to a dedicated fast path and a moderate
8126 amount of loop unrolling.
8127
Antoine Pitrou14b78f52009-01-09 22:27:08 +00008128- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
8129 collecting the oldest generation) so that allocating lots of objects without
8130 destroying them does not show quadratic performance. Based on a proposal by
8131 Martin von Löwis at
8132 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
8133
Vinay Sajip6268cbc2009-01-21 00:19:28 +00008134- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00008135 having been closed (for instance, a read() call could return some
8136 previously buffered data). Patch by Dmitry Vasiliev.
8137
Antoine Pitrou05608432009-01-09 18:53:14 +00008138- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
8139 flag to work properly. Furthermore, when specifying -u, the text stdout
8140 and stderr streams have line-by-line buffering enabled (the default being
8141 to buffer arbitrary chunks of data).
8142
Raymond Hettinger35631532009-01-09 03:58:09 +00008143- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
8144 instead of ints (reducing its size from 4 to 8 times thereby reducing
8145 Python's overall memory).
8146
Antoine Pitroud35cbf62009-01-06 19:02:24 +00008147- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
8148 an existing .py counterpart, override the co_filename attributes of all
8149 code objects if the original filename is obsolete (which can happen if the
8150 file has been renamed, moved, or if it is accessed through different paths).
8151 Patch by Ziga Seilnacht and Jean-Paul Calderone.
8152
Antoine Pitrouc3b39242009-01-03 16:59:18 +00008153- Issue #4580: Fix slicing of memoryviews when the item size is greater than
8154 one byte. Also fixes the meaning of len() so that it returns the number of
8155 items, rather than the size in bytes.
8156
Martin v. Löwis5c88d812009-01-02 20:47:48 +00008157- Issue #4075: Use OutputDebugStringW in Py_FatalError.
8158
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00008159- Issue #4747: When the terminal does not use utf-8, executing a script with
8160 non-ascii characters in its name could fail with a "SyntaxError: None" error.
8161
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008162- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
8163 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00008164
Antoine Pitrou7ddda782009-01-01 15:35:33 +00008165- Issue #3680: Reference cycles created through a dict, set or deque iterator
8166 did not get collected.
8167
Nick Coghlanf1f2f682008-12-30 07:29:12 +00008168- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
8169 where the tp_hash and tp_dict slots are both NULL.
8170
Georg Brandlccc47b62008-12-28 11:44:14 +00008171- Issue #4759: None is now allowed as the first argument of
8172 bytearray.translate(). It was always allowed for bytes.translate().
8173
Skip Montanaro80072cb2008-12-23 03:51:14 +00008174- Added test case to ensure attempts to read from a file opened for writing
8175 fail.
8176
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00008177- Issue #3106: Speedup some comparisons (str/str and int/int).

8181
Antoine Pitrou621601a2008-12-17 23:18:19 +00008182- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
8183 print elapsed times, not only when some objects are uncollectable /
8184 unreachable. Original patch by Neil Schemenauer.
8185
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00008186- Issue #3439: Add a bit_length method to int.
8187
Mark Dickinsonda2706b2008-12-11 18:03:03 +00008188- Issue #2173: When getting device encoding, check that return value of
8189 nl_langinfo is not the empty string. This was causing silent build
8190 failures on OS X.
8191
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00008192- Issue #4597: Fixed several opcodes that weren't always propagating
8193 exceptions.
8194
8195- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00008196 context manager returns a value that cannot be converted to a bool.
8197
Mark Dickinsonfd24b322008-12-06 15:33:31 +00008198- Issue #4445: Replace "sizeof(PyBytesObject)" with
8199 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
8200 bytes instances. On a typical machine this saves 3 bytes of memory
8201 (on average) per allocation of a bytes instance.
8202
Christian Heimesa872de52008-12-05 08:26:55 +00008203- Issue #4533: File read operation was dreadfully slow due to a slowly
8204 growing read buffer. Fixed by using the same growth rate algorithm as
8205 Python 2.x.
8206
Antoine Pitrou5504e892008-12-06 21:27:53 +00008207- Issue #4509: Various issues surrounding resize of bytearray objects to
8208 which there are buffer exports (e.g. memoryview instances).
8209
Georg Brandlf9734072008-12-07 15:30:06 +00008210- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
8211 method on file objects with closefd=False. The file descriptor is still
8212 kept open but the file object behaves like a closed file. The ``FileIO``
8213 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00008214
Antoine Pitroubc420402008-12-07 20:14:49 +00008215- Issue #4569: Interpreter crash when mutating a memoryview with an item size
8216 larger than 1.

8221
Walter Dörwaldc1651a02009-05-03 22:55:55 +00008222- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
8223 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
8224 step. This avoids problems with counting UTF-8 bytes that ignores the effect
8225 of using the replace error handler in PyUnicode_DecodeUTF8().
