6===========================
7
8*Release date: XX-XXX-2011*
9
10Core and Builtins
11-----------------
12
Antoine Pitrou2be60af2012-01-24 17:44:06 +010013- Issue #11235: Fix OverflowError when trying to import a source file whose
14 modification time doesn't fit in a 32-bit timestamp.
15
Antoine Pitrou6c40eb72012-01-18 20:16:09 +010016- Fix the builtin module initialization code to store the init function for
17 future reinitialization.
18
Gregory P. Smith9564e4c2012-01-21 14:50:11 -080019- Issue #8052: The posix subprocess module would take a long time closing
20 all possible file descriptors in the child process rather than just open
21 file descriptors. It now closes only the open fds if possible for the
22 default close_fds=True behavior.
23
Meador Inge33880602012-01-15 19:15:36 -060024- Issue #13629: Renumber the tokens in token.h so that they match the indexes

28 effect of appearing to resolve the issue. Thanks to Mark Shannon for
29 noticing.
30
Alexandre Vassalotti3bfc65a2011-12-13 13:08:09 -050031- Issue #13505: Pickle bytes objects in a way that is compatible with

35 given by Campbell Barton).
36
Antoine Pitrou11942a52011-11-28 19:08:36 +010037- Issue #7111: Python can now be run without a stdin, stdout or stderr
38 stream. It was already the case with Python 2. However, the corresponding
39 sys module entries are now set to None (instead of an unusable file object).
40
Amaury Forgeot d'Arc58e87612011-11-22 21:51:55 +010041- Issue #13436: Fix a bogus error message when an AST object was passed
42 an invalid integer value.
43
Petri Lehtinen8d40f162011-11-19 22:03:10 +020044- Issue #13338: Handle all enumerations in _Py_ANNOTATE_MEMORY_ORDER
45 to allow compiling extension modules with -Wswitch-enum on gcc.

47
Antoine Pitrou5418ee02011-11-15 01:42:21 +010048- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
49 already accepts them).
50
Antoine Pitrou0d776b12011-11-06 00:34:26 +010051- Issue #13342: input() used to ignore sys.stdin's and sys.stdout's unicode
52 error handler in interactive mode (when calling into PyOS_Readline()).
53
Amaury Forgeot d'Arc97c1bef2011-11-04 22:17:45 +010054- Issue #13343: Fix a SystemError when a lambda expression uses a global
55 variable in the default value of a keyword-only argument:
56 (lambda *, arg=GLOBAL_NAME: None)
57
Petri Lehtinencd06a142011-10-30 20:59:10 +020058- Issue #10519: Avoid unnecessary recursive function calls in
59 setobject.c.
60

Antoine Pitrou551ba202011-10-18 16:40:50 +020073- Issue #13188: When called without an explicit traceback argument,
74 generator.throw() now gets the traceback from the passed exception's
75 ``__traceback__`` attribute. Patch by Petri Lehtinen.
76
Mark Hammond6c58b282011-10-17 11:05:57 +110077- Issue #7833: Extension modules built using distutils on Windows will no
78 longer include a "manifest" to prevent them failing at import time in some
79 embedded situations.
80

772 and was unreliable since tests or user programs could modify the interpreter
773 environment after Distutils set it. Instead, have Distutils set the the
774 deployment target only in the environment of each build subprocess. It is
775 still possible to globally override the default by setting
776 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
777 greater or equal to the default value, the value with which the interpreter
778 was built.

R. David Murrayb7deff12011-01-30 06:21:28 +00001451- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
1452 files in binary mode, using the email package's binary support to parse
1453 arbitrary email messages. StringIO and text file input is deprecated,
1454 and string input fails early if non-ASCII characters are used, where
1455 previously it would fail when the email was processed in a later step.
1456
Nick Coghlan793ee1f2011-01-30 01:24:08 +00001457- Issue #10845: Mitigate the incompatibility between the multiprocessing
1458 module on Windows and the use of package, zipfile or directory execution
1459 by special casing main modules that actually *are* called __main__.py.
1460
Éric Araujoac4e58e2011-01-29 20:32:11 +00001461- Issue #11045: Protect logging call against None argument.

1464 commands.
1465
Ned Deily806c9442011-01-29 18:43:56 +00001466- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
1467 preventing a confusing hung appearance on OS X with the windows
1468 obscured.
1469
Ned Deily70063932011-01-29 18:29:01 +00001470- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the
1471 menu accelerators for Open Module, Go to Line, and New Indent Width.
1472 The accelerators still work but no longer appear in the menu items.
1473

Raymond Hettinger8b5eb2f2011-01-27 00:06:54 +00001476- Issue #11020: Command-line pyclbr was broken because of missing 2-to-3
1477 conversion.
1478
R. David Murray7372a072011-01-26 21:21:32 +00001479- Issue #11019: Fixed BytesGenerator so that it correctly handles a Message
1480 with a None body.
1481
Raymond Hettingera63a3122011-01-26 20:34:14 +00001482- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
1483 keyword-only argument. The preceding positional argument was deprecated,
1484 so it made no sense to add filter as a positional argument.
1485
Raymond Hettinger512d2cc2011-01-25 21:32:39 +00001486- Issue #11004: Repaired edge case in deque.count().
1487
Ned Deily122539e2011-01-24 21:46:44 +00001488- Issue #10974: IDLE no longer crashes if its recent files list includes files
1489 with non-ASCII characters in their path names.
1490
Raymond Hettingerbf1d2bc2011-01-24 04:52:27 +00001491- Have hashlib.algorithms_available and hashlib.algorithms_guaranteed both
1492 return sets instead of one returning a tuple and the other a frozenset.

1497
Victor Stinnerf2e439f2011-01-23 00:11:58 +00001498- Issue #10955: zipimport uses ASCII encoding instead of cp437 to decode
Victor Stinner4ee65a92011-01-22 10:30:29 +00001499 filenames, at bootstrap, if the codec registry is not ready yet. It is still
1500 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +00001501 for all file entries in the ZIP file.
Victor Stinner4ee65a92011-01-22 10:30:29 +00001502

1509 a symbol named FSTAT.
1510
Armin Ronacher8d96d772011-01-22 13:13:05 +00001511- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1512 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1513 of HTTP 1.1.
1514
Armin Ronacher59531282011-01-22 13:44:22 +00001515- To match the behaviour of HTTP server, the HTTP client library now also
1516 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1517 that for incoming headers which makes this behaviour now consistent in
1518 both incoming and outgoing direction.
1519
Steven Bethardb0270112011-01-24 21:02:50 +00001520- Issue #9509: argparse now properly handles IOErrors raised by

1524 during request handling.
1525
Georg Brandl0f6b47a2011-01-30 12:19:35 +00001526- Issue #10680: Fix mutually exclusive arguments for argument groups in
1527 argparse.

Georg Brandl255abdd2011-01-16 14:17:26 +00001554- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
1555 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
1556 translates newlines (\r\n => \n).

Martin v. Löwisc83bc3c2011-01-06 19:15:47 +00001558- Remove buffer API from stable ABI for now, see #10181.

1561 doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int
1562 (length bigger than 2^31-1 bytes).
1563
Victor Stinnerdc555402011-01-04 13:15:39 +00001564- Issue #9015, #9611: FileIO.readinto(), FileIO.write(), os.write() and
Victor Stinnerc655a722011-07-05 11:31:49 +02001565 stdprinter.write() clamp the length to INT_MAX on Windows.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001618- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001619 continuation line in the formatted value has no leading white space and looks
1620 like a header. Since Generator uses Header to format all headers, this check
1621 is made for all headers in any serialized message at serialization time. This
1622 provides protection against header injection attacks.

Georg Brandl255abdd2011-01-16 14:17:26 +00001632 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001633
Éric Araujof0ab5d62011-05-29 03:43:59 +02001634- email.header.Header was incorrectly encoding folding whitespace when

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002273- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2274 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002275 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002276 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002277 encoding and to encode command line arguments on this OS.

2282
Benjamin Peterson230b2062010-10-16 03:45:45 +00002283- Issue #9997: Don't let the name "top" have special significance in scope

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002390 incorrectly validated some non-compliant applications as WSGI compliant; if

2670 with a non-empty format string. This is an effort to future-proof user
2671 code. If a derived class does not currently implement __format__ but later
2672 adds its own __format__, it would most likely break user code that had
2673 supplied a format string. This will be changed to a DeprecationWaring in
2674 Python 3.3 and it will be an error in Python 3.4.

2678 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002687- Issue #4617: Previously it was illegal to delete a name from the local
2688 namespace if it occurs as a free variable in a nested block. This limitation
2689 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2690
Georg Brandl27a28582010-10-10 09:49:21 +00002691- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2692 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2693 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2694 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002729- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002730 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002731 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002732 replacement for old handle_accept() and avoids the user to call accept()
2733 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002756- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002757 retry the select() loop instead of bailing out. This is because select() can
2758 incorrectly report a socket as ready for reading (for example, if it received
2759 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002760

Georg Brandl27a28582010-10-10 09:49:21 +00002764 received. Now sendall() properly calls signal handlers if necessary, and
2765 retries sending if these returned successfully, including on sockets with a
2766 timeout.

Georg Brandl27a28582010-10-10 09:49:21 +00002806 non-blocking mode: they return None when an operation would block (instead of

Antoine Pitrou328ec742010-09-14 18:37:24 +00002818
Georg Brandl27a28582010-10-10 09:49:21 +00002819- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2820 supporting the whole socket API (rather than the "raw" _socket.socket
2821 objects).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002839- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002840 it possible for the user to create self-referencing ordered dictionaries which
2841 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002842 approach of using weakref proxies so that reference cycles never get created
2843 in the first place.
2844
Victor Stinnercb043522010-09-10 23:49:04 +00002845- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2846 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002847 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002848
Georg Brandl27a28582010-10-10 09:49:21 +00002849- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2850 environment variable to set the filesystem encoding at Python startup.
2851 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2852 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002853
Georg Brandl27a28582010-10-10 09:49:21 +00002854- Issue #9410: Various optimizations to the pickle module, leading to speedups

Vinay Sajip121a1c42010-09-08 10:46:15 +00002861- Logging: Added QueueHandler class to facilitate logging usage with
2862 multiprocessing.
2863
Georg Brandl27a28582010-10-10 09:49:21 +00002864- Issue #9707: Rewritten reference implementation of threading.local which is
2865 friendlier towards reference cycles. This change is not normally visible
2866 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002867
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002868- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2869 still return the id of the parent process after it has exited. This process
2870 id may even have been reused by another unrelated process.
2871
Georg Brandl27a28582010-10-10 09:49:21 +00002872- Issue #9792: In case of connection failure, socket.create_connection() would
2873 swallow the exception and raise a new one, making it impossible to fetch the
2874 original errno, or to filter timeout errors. Now the original error is
2875 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002877- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2878 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2879 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002881- Updates to the random module:
2882
Georg Brandl27a28582010-10-10 09:49:21 +00002883 * Document which parts of the module are guaranteed to stay the same across
2884 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002885
Georg Brandl27a28582010-10-10 09:49:21 +00002886 * Update the seed() method to use all of the bits in a string instead of just
2887 the hash value. This makes better use of the seed value and assures the
2888 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002889
Georg Brandl27a28582010-10-10 09:49:21 +00002890 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2891 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2892 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002893
2894 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002913- hashlib has two new constant attributes: algorithms_guaranteed and
2914 algorithms_avaiable that respectively list the names of hash algorithms
2915 guaranteed to exist in all Python implementations and the names of hash
2916 algorithms available in the current process.
2917

3045 return characters from the full Unicode range, even on narrow unicode builds
3046 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3047 in Python is that unicodedata.numeric() now returns the correct value for
3048 large code points, and repr() may consider more characters as printable.

Victor Stinner47fcb5b2010-08-13 23:59:58 +00003066- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003067 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3068 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00003074- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3075 use PyUnicode_FromFormatV() to format the warning message.

3083 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003084
Georg Brandl649971e2010-09-05 17:06:50 +00003085- Issue #9416: Fix some issues with complex formatting where the output with no
3086 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003087
3088 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3089 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3654 parsing certain long numeric strings corresponding to subnormal values, (3) a
3655 memory leak for some values large enough to cause overflow, and (4) a number
3656 of flaws that could lead to incorrectly rounded results.

Georg Brandl62069d32010-07-31 08:56:11 +00004351- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandl62069d32010-07-31 08:56:11 +00004360- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4361 InvalidOperation instead of returning False. (Comparisons involving a quiet
4362 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4363 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004365- Issue #2531: Comparison operations between floats and Decimal instances now
4366 return a result based on the numeric values of the operands; previously they
4367 returned an arbitrary result based on the relative ordering of id(float) and
4368 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4369 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004370
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004371- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004373- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004374 argument `-` which tells it to read files to compile from stdin. Each line is
4375 read on demand and the named file is compiled immediately. (Original patch by
4376 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00004382- Comparisons using one of <, <=, >, >= between a complex instance and a
4383 Fractions instance now raise TypeError instead of returning True/False. This
4384 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4385 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004428- The internals of the subprocess module on POSIX systems have been replaced by
4429 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4430 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004431
Georg Brandl62069d32010-07-31 08:56:11 +00004432- subprocess.Popen now has restore_signals and start_new_session features. The
4433 default of restore_signals=True is a new behavior compared to earlier Python
4434 versions. This means that signals such as SIGPIPE are not ignored by default
4435 in subprocesses launched by Python (Issue #1652).

4522 position when calling `truncate()`. It would previously change the file
4523 position to the given argument, which goes against the tradition of

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004928- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004929 compared to other unix systems. In particular, os.getgroups() does not reflect
4930 any changes made using os.setgroups() but basicly always returns the same
4931 information as the id command. os.getgroups() can now return more than 16
4932 groups on MacOSX.

5577Core and Builtins
5578-----------------
5579
Mark Dickinson865e01a2009-05-07 16:37:01 +00005580- Issue #5914: Add new C API function PyOS_string_to_double, and
5581 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5582
Eric Smith741191f2009-05-06 13:08:15 +00005583- Issue #3382: float.__format__, complex.__format__, and %-formatting
5584 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5585 affects nan -> NAN and inf -> INF.
5586
Mark Hammond5a607a32009-05-06 08:04:54 +00005587- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5588 in all operations, including splitdrive, split, etc. splitunc() now issues
5589 a PendingDeprecation warning.
5590
Eric Smith63376222009-05-05 14:04:18 +00005591- Issue #5920: For float.__format__, change the behavior with the
5592 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5593 to be like 'g' but with at least one decimal point and with a
5594 default precision of 12. Previously, the behavior the same but with
5595 a default precision of 6. This more closely matches str(), and
5596 reduces surprises when adding alignment flags to the empty
5597 presentation type. This also affects the new complex.__format__ in
5598 the same way.
5599
Martin v. Löwis011e8422009-05-05 04:43:17 +00005600- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5601
R. David Murrayb18500d2009-05-04 22:59:07 +00005602- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5603 shadowed by classtype's, even if it was None. property now
5604 inserts the __doc__ into the subclass instance __dict__.
5605
Antoine Pitrou244651a2009-05-04 18:56:13 +00005606- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5607 sequences. Patch by Nick Barnes and Victor Stinner.
5608
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005609- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005610
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005611- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5612 received a new method, detach(). detach() disconnects the underlying stream
5613 from the buffer or text IO and returns it.
5614
Mark Dickinson33841c32009-05-01 15:37:04 +00005615- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5616 floats with absolute value over 1e50. Also remove length
5617 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5618 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005619
Eric Smith741191f2009-05-06 13:08:15 +00005620- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005621 format(complex(1, 2./3), '.5') now produces a sensible result.
5622
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005623- Issue #5864: Fix empty format code formatting for floats so that it
5624 never gives more than the requested number of significant digits.
5625
Eric Smith6dc46f52009-04-27 20:39:49 +00005626- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5627 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5628
Eric Smithcc32a112009-04-26 21:35:14 +00005629- Issue #5835: Deprecate PyOS_ascii_formatd.
5630
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005631- Issue #4971: Fix titlecase for characters that are their own
5632 titlecase, but not their own uppercase.
5633
Benjamin Peterson193152c2009-04-25 01:08:45 +00005634- Issue #5283: Setting __class__ in __del__ caused a segfault.
5635
Mark Dickinsonad476da2009-04-23 19:14:16 +00005636- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5637 z involves nans, infs or negative zeros.
5638
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005639- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005640
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005641- Issue #1869 (and many duplicates): make round(x, n) correctly
5642 rounded for a float x, by using the decimal <-> binary conversions
5643 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5644 consistently agrees with format(x, '.2f').
5645
Benjamin Petersonae937c02009-04-18 20:54:08 +00005646- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5647 some builtin types.
5648
Eric Smith0923d1d2009-04-16 20:16:10 +00005649- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5650
Eric Smith35e84722009-04-16 20:21:28 +00005651- Issue #5515: str.format() type 'n' combined with commas and leading
5652 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005653
5654- Implement PEP 378, Format Specifier for Thousands Separator, for
5655 floats.
5656
Mark Dickinson3370cce2009-04-17 22:40:53 +00005657- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005658 1e11, not 1e12. This avoids printing 13 significant digits in
5659 situations where only 12 of them are correct. Example problem
5660 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5661 long time.)
5662
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005663- Issue #1580: On most platforms, use a 'short' float repr: for a
5664 finite float x, repr(x) now outputs a string based on the shortest
5665 sequence of decimal digits that rounds to x. Previous behaviour was
5666 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005667 Another minor difference is that the new repr switches to
5668 exponential notation at 1e16 instead of the previous 1e17; this
5669 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005670
5671 There's a new sys attribute sys.float_repr_style, which takes
5672 the value 'short' to indicate that we're using short float repr,
5673 and 'legacy' if the short float repr isn't available for one
5674 reason or another.
5675
5676 The float repr change involves incorporating David Gay's 'perfect
5677 rounding' code into the Python core (it's in Python/dtoa.c). As a
5678 secondary consequence, all string-to-float and float-to-string
5679 conversions (including all float formatting operations) will be
5680 correctly rounded on these platforms.
5681
Georg Brandl5f90d792010-08-01 22:31:05 +00005682 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005683 this change does not apply.
5684
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005685- Issue #5759: float() didn't call __float__ on str subclasses.
5686
Georg Brandlabc38772009-04-12 15:51:51 +00005687- The string.maketrans() function is deprecated; there is a new static method
5688 maketrans() on the bytes and bytearray classes. This removes confusion about
5689 the types string.maketrans() is supposed to work with, and mirrors the
5690 methods available on the str class.
5691
R. David Murraydc6da8a2009-04-09 22:16:43 +00005692- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5693 its clarity and its speed.
5694
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005695- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005696 to avoid compiler warnings.
5697
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005698- Issue #3739: The unicode-internal encoder now reports the number of characters
5699 consumed like any other encoder (instead of the number of bytes).

Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005863- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
5864 improve its performance. Long divisions and remainder operations
5865 are now between 50% and 150% faster.
5866
Mark Dickinsonbd792642009-03-18 20:06:12 +00005867- Issue #4258: Make it possible to use base 2**30 instead of base
5868 2**15 for the internal representation of integers, for performance
5869 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5870 --enable-big-digits option to configure, which overrides the
5871 default. Add sys.int_info structseq to provide information about
5872 the internal format.

5982 rotating the object pointer by 4 bits to the right.
5983
Mark Dickinson87ec0852009-02-09 17:15:59 +00005984- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5985 it now forces its argument to double before testing for infinity.
5986
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005987- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5988 returns a non-number type.
5989
Benjamin Peterson87618552009-02-08 15:00:52 +00005990- Issue #5182: Removed memoryview.__str__.

5995 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005996
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005997- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005998 were suppressing all exceptions. These include list() and bytearray().
5999
Mark Dickinson1124e712009-01-28 21:25:58 +00006000- Issue #4707: round(x, n) now returns an integer if x is an integer.
6001 Previously it returned a float.
6002
Antoine Pitroub52ec782009-01-25 16:34:23 +00006003- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6004 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6005 evaluation loop is compiled with a new dispatch mechanism which gives
6006 speedups of up to 20%, depending on the system, on various benchmarks.
6007
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006008- Issue #4874: Most builtin decoders now reject unicode input.

6016 optional module state data.
6017
Mark Dickinson8055afd2009-01-17 10:04:45 +00006018- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006019 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006020
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006021- Issue #4935: The overflow checking code in the expandtabs() method common
6022 to str, bytes and bytearray could be optimized away by the compiler, letting
6023 the interpreter segfault instead of raising an error.
6024
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006025- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6026 __next__ method.
6027
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006028- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6029 function no longer attempt to call the __long__ slot to convert an object
6030 to an integer. Only the __int__ and __trunc__ slots are examined.
6031
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006032- Issue #4893: Use NT threading on CE.

6035
Antoine Pitrouab868312009-01-10 15:40:25 +00006036- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6037 common cases are optimized thanks to a dedicated fast path and a moderate
6038 amount of loop unrolling.
6039
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006040- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6041 collecting the oldest generation) so that allocating lots of objects without
6042 destroying them does not show quadratic performance. Based on a proposal by
6043 Martin von Löwis at
6044 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6045
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006046- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006047 having been closed (for instance, a read() call could return some
6048 previously buffered data). Patch by Dmitry Vasiliev.
6049
Antoine Pitrou05608432009-01-09 18:53:14 +00006050- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6051 flag to work properly. Furthermore, when specifying -u, the text stdout
6052 and stderr streams have line-by-line buffering enabled (the default being
6053 to buffer arbitrary chunks of data).
6054
Raymond Hettinger35631532009-01-09 03:58:09 +00006055- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6056 instead of ints (reducing its size from 4 to 8 times thereby reducing
6057 Python's overall memory).
6058
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006059- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6060 an existing .py counterpart, override the co_filename attributes of all
6061 code objects if the original filename is obsolete (which can happen if the
6062 file has been renamed, moved, or if it is accessed through different paths).
6063 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6064
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006065- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6066 one byte. Also fixes the meaning of len() so that it returns the number of
6067 items, rather than the size in bytes.
6068
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006069- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6070
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006071- Issue #4747: When the terminal does not use utf-8, executing a script with
6072 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6073
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006074- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6075 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006076
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006077- Issue #3680: Reference cycles created through a dict, set or deque iterator
6078 did not get collected.
6079
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006080- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6081 where the tp_hash and tp_dict slots are both NULL.
6082
Georg Brandlccc47b62008-12-28 11:44:14 +00006083- Issue #4759: None is now allowed as the first argument of
6084 bytearray.translate(). It was always allowed for bytes.translate().
6085
Skip Montanaro80072cb2008-12-23 03:51:14 +00006086- Added test case to ensure attempts to read from a file opened for writing
6087 fail.
6088
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006089- Issue #3106: Speedup some comparisons (str/str and int/int).

6099
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006100- Issue #2173: When getting device encoding, check that return value of
6101 nl_langinfo is not the empty string. This was causing silent build
6102 failures on OS X.
6103
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006104- Issue #4597: Fixed several opcodes that weren't always propagating
6105 exceptions.
6106
6107- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006108 context manager returns a value that cannot be converted to a bool.
6109
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006110- Issue #4445: Replace "sizeof(PyBytesObject)" with
6111 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6112 bytes instances. On a typical machine this saves 3 bytes of memory
6113 (on average) per allocation of a bytes instance.
6114
Christian Heimesa872de52008-12-05 08:26:55 +00006115- Issue #4533: File read operation was dreadfully slow due to a slowly
6116 growing read buffer. Fixed by using the same growth rate algorithm as
6117 Python 2.x.
6118
Antoine Pitrou5504e892008-12-06 21:27:53 +00006119- Issue #4509: Various issues surrounding resize of bytearray objects to
6120 which there are buffer exports (e.g. memoryview instances).
6121
Georg Brandlf9734072008-12-07 15:30:06 +00006122- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6123 method on file objects with closefd=False. The file descriptor is still
6124 kept open but the file object behaves like a closed file. The ``FileIO``
6125 object also got a new readonly attribute ``closefd``.

6135 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6136 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6137 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00006739- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6740 regression tests in parallel, shortening the total runtime.
6741
Guilherme Polo2a998fa2009-06-21 17:40:07 +00006742- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6743 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6744 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6745 skip the tests if DISPLAY is defined but can't be used.
6746
R. David Murraya21e4ca2009-03-31 23:16:50 +00006747- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006748 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006749 from test support, which does the conversion.
6750
Guilherme Polo9de29af2009-01-28 20:40:48 +00006751- Issue #5083: New 'gui' resource for regrtest.
