Ned Deily657b2de2011-06-28 19:51:30 -0700612- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
613 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
614 interpreter process. This could cause failures in non-Distutils subprocesses
615 and was unreliable since tests or user programs could modify the interpreter
616 environment after Distutils set it. Instead, have Distutils set the the
617 deployment target only in the environment of each build subprocess. It is
618 still possible to globally override the default by setting
619 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
620 greater or equal to the default value, the value with which the interpreter

1399 twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides
1400 as an easy platform-independent way to run test suite with sensible defaults.

Nick Coghlan793ee1f2011-01-30 01:24:08 +00001683- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
1684 files in binary mode, using the email package's binary support to parse
1685 arbitrary email messages. StringIO and text file input is deprecated,
1686 and string input fails early if non-ASCII characters are used, where
Éric Araujoac4e58e2011-01-29 20:32:11 +00001687 previously it would fail when the email was processed in a later step.

1715 keyword-only argument. The preceding positional argument was deprecated,
1716 so it made no sense to add filter as a positional argument.

Antoine Pitrou305bc9e2011-01-20 21:07:24 +00001731 filenames, at bootstrap, if the codec registry is not ready yet. It is still
1732 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)

1745 of HTTP 1.1.
Steven Bethardb0270112011-01-24 21:02:50 +00001746
1747- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00001748 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00001749 that for incoming headers which makes this behaviour now consistent in
1750 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001846- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001847 continuation line in the formatted value has no leading white space and looks
1848 like a header. Since Generator uses Header to format all headers, this check
1849 is made for all headers in any serialized message at serialization time. This
1850 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001851

Georg Brandl255abdd2011-01-16 14:17:26 +00001860 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001861
Éric Araujof0ab5d62011-05-29 03:43:59 +02001862- email.header.Header was incorrectly encoding folding whitespace when

1864 folding whitespace. It now uses the continuation_ws, as it does for

1870 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1871 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1872 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002503- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2504 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002505 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002506 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002507 encoding and to encode command line arguments on this OS.

2510 filenames encoded to the filesystem encoding with the surrogateescape error

2512
Benjamin Peterson230b2062010-10-16 03:45:45 +00002513- Issue #9997: Don't let the name "top" have special significance in scope
2514 resolution.

2902 with a non-empty format string. This is an effort to future-proof user
2903 code. If a derived class does not currently implement __format__ but later
2904 adds its own __format__, it would most likely break user code that had
2905 supplied a format string. This will be changed to a DeprecationWaring in
2906 Python 3.3 and it will be an error in Python 3.4.

2910 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 +00002919- Issue #4617: Previously it was illegal to delete a name from the local
2920 namespace if it occurs as a free variable in a nested block. This limitation
2921 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2922
Georg Brandl27a28582010-10-10 09:49:21 +00002923- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2924 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2925 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2926 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002961- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002962 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002963 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002964 replacement for old handle_accept() and avoids the user to call accept()
2965 directly.

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003071- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003072 it possible for the user to create self-referencing ordered dictionaries which
3073 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003074 approach of using weakref proxies so that reference cycles never get created
3075 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00003081- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3082 environment variable to set the filesystem encoding at Python startup.
3083 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3084 reencode all filenames in all objects.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003100- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3101 still return the id of the parent process after it has exited. This process
3102 id may even have been reused by another unrelated process.
3103
Georg Brandl27a28582010-10-10 09:49:21 +00003104- Issue #9792: In case of connection failure, socket.create_connection() would

Georg Brandl27a28582010-10-10 09:49:21 +00003118 * Update the seed() method to use all of the bits in a string instead of just
3119 the hash value. This makes better use of the seed value and assures the
3120 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003121
Georg Brandl27a28582010-10-10 09:49:21 +00003122 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3123 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3124 which has a slight bias whenever n is not a power of two. Issue #9025.

3126 * Improved documentation of arguments to randrange(). Issue #9379.

3254 now removed, since their effect was inexistent in 3.x (the default encoding is

3277 return characters from the full Unicode range, even on narrow unicode builds
3278 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3279 in Python is that unicodedata.numeric() now returns the correct value for
3280 large code points, and repr() may consider more characters as printable.
3281
Victor Stinner6c00c142010-08-17 23:37:11 +00003282- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Victor Stinner47fcb5b2010-08-13 23:59:58 +00003298- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003299 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3300 objects are output as-is.

3304 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00003305
Georg Brandl649971e2010-09-05 17:06:50 +00003306- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3307 use PyUnicode_FromFormatV() to format the warning message.

3315 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003316
Georg Brandl649971e2010-09-05 17:06:50 +00003317- Issue #9416: Fix some issues with complex formatting where the output with no
3318 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003319
3320 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3321 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3887 memory leak for some values large enough to cause overflow, and (4) a number
3888 of flaws that could lead to incorrectly rounded results.

Georg Brandl62069d32010-07-31 08:56:11 +00004578 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4579 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00004580
Raymond Hettingerc50846a2010-04-05 18:56:31 +00004581- Add functools.total_ordering() and functools.cmp_to_key().
4582
Georg Brandl62069d32010-07-31 08:56:11 +00004583- Issue #8257: The Decimal construct now accepts a float instance directly,
4584 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004585
4586 >>> Decimal(1.1)
4587 Decimal('1.100000000000000088817841970012523233890533447265625')
4588
Georg Brandl62069d32010-07-31 08:56:11 +00004589- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4590 directly.
Mark Dickinson98127c32010-04-03 11:18:52 +00004591
Georg Brandl62069d32010-07-31 08:56:11 +00004592- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4593 InvalidOperation instead of returning False. (Comparisons involving a quiet
4594 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4595 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004596
Georg Brandl62069d32010-07-31 08:56:11 +00004597- Issue #2531: Comparison operations between floats and Decimal instances now
4598 return a result based on the numeric values of the operands; previously they
4599 returned an arbitrary result based on the relative ordering of id(float) and
4600 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4601 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004602
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004603- Added a subtract() method to collections.Counter().
4604
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004605- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004606 argument `-` which tells it to read files to compile from stdin. Each line is
4607 read on demand and the named file is compiled immediately. (Original patch by
4608 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004609
Florent Xicluna806d8cf2010-03-30 19:34:18 +00004610- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4611 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00004612 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna806d8cf2010-03-30 19:34:18 +00004613
Georg Brandl62069d32010-07-31 08:56:11 +00004614- Comparisons using one of <, <=, >, >= between a complex instance and a
4615 Fractions instance now raise TypeError instead of returning True/False. This
4616 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4617 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004619- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some

Florent Xiclunafd1b0932010-03-28 00:25:02 +00004623- Issue #8205: Remove the "Modules" directory from sys.path when Python is
4624 running from the build directory (POSIX only).
4625
Antoine Pitrou910bd512010-03-22 20:11:09 +00004626- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004627 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4628 silenced.

Georg Brandl62069d32010-07-31 08:56:11 +00004630- Issue #7860: platform.uname now reports the correct 'machine' type when Python
4631 is running in WOW64 mode on 64 bit Windows.
R. David Murrayca2edce2010-03-22 17:48:48 +00004632
Antoine Pitrou3c0fac22010-03-26 19:36:14 +00004633- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
4634 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4635 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +00004636
Victor Stinnere3a1f6d2010-03-22 01:58:35 +00004637- Issue #4282: Fix the main function of the profile module for a non-ASCII

4644
Benjamin Peterson00888932010-03-18 22:37:38 +00004645- Issue #8168: py_compile now handles files with utf-8 BOMS.
4646
Benjamin Peterson689a5582010-03-18 22:29:52 +00004647- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
4648 detected.
4649
Martin v. Löwis4b003072010-03-16 13:19:21 +00004650- Issue #6716/2: Backslash-replace error output in compilall.

4653 with Tcl/Tk-8.5.
4654
Georg Brandl62069d32010-07-31 08:56:11 +00004655- Issue #8140: extend compileall to compile single files. Add -i option.

Georg Brandl62069d32010-07-31 08:56:11 +00004657- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of the
4658 locale.
Matthias Klose82f60912010-03-15 13:46:04 +00004659
Georg Brandl62069d32010-07-31 08:56:11 +00004660- The internals of the subprocess module on POSIX systems have been replaced by
4661 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4662 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004663
Georg Brandl62069d32010-07-31 08:56:11 +00004664- subprocess.Popen now has restore_signals and start_new_session features. The
4665 default of restore_signals=True is a new behavior compared to earlier Python
4666 versions. This means that signals such as SIGPIPE are not ignored by default
4667 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00004668
Florent Xiclunaf15351d2010-03-13 23:24:31 +00004669- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

Gerhard Häringf9cee222010-03-05 15:20:03 +00004681- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
4682 bugs and allows loading SQLite extensions from shared libraries.
4683
Ezio Melottida227042010-03-14 11:51:00 +00004684- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public

Georg Brandl62069d32010-07-31 08:56:11 +00004728- Issue #7633: In the decimal module, Context class methods (with the exception
4729 of canonical and is_canonical) now accept instances of int and long wherever a
4730 Decimal instance is accepted, and implicitly convert that argument to Decimal.
4731 Previously only some arguments were converted.

Georg Brandl62069d32010-07-31 08:56:11 +00004753- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
4754 position when calling `truncate()`. It would previously change the file
4755 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004756 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4757
Antoine Pitroua32f9a22010-01-27 21:18:57 +00004758- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00004759 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
4760 archive. The new implementation is significantly faster and can be wrapped in
4761 a :class:`io.BufferedReader` object for more speedups. It also solves an
4762 issue where interleaved calls to `read()` and `readline()` give wrong results.
4763 Patch by Nir Aides.

Georg Brandl62069d32010-07-31 08:56:11 +00005099 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
5100 PyPycLoader inherit from this class and provide implementations in relation to
5101 other methods required by the ABCs.

Brett Cannon64ef00f2009-07-20 03:19:18 +00005103- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
5104 the documentation said it did even though the code in PyLoader relied on the
5105 abstract method required by ResourceLoader.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005160- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005161 compared to other unix systems. In particular, os.getgroups() does not reflect
5162 any changes made using os.setgroups() but basicly always returns the same
5163 information as the id command. os.getgroups() can now return more than 16
5164 groups on MacOSX.

5190 Prior to this change, timezone adjustment in utctimetuple() could produce
5191 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

5195 directive. When the ``%z`` directive is present in the format string, an
5196 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5197 ``datetime.timezone`` instance constructed from the parsed offset. If both
5198 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5199 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005202 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5203 ``datetime.timezone``, return fixed name and UTC offset from their
5204 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5205 returns ``None``. A class attribute, ``utc`` contains an instance
5206 representing the UTC timezone. Original patch by Rafe Kaplan.

5232 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005233 the result is now always correctly rounded, and is equivalent to ``td /

Mark Dickinson865e01a2009-05-07 16:37:01 +00005812- Issue #5914: Add new C API function PyOS_string_to_double, and
5813 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5814
Eric Smith741191f2009-05-06 13:08:15 +00005815- Issue #3382: float.__format__, complex.__format__, and %-formatting
5816 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5817 affects nan -> NAN and inf -> INF.
5818
Mark Hammond5a607a32009-05-06 08:04:54 +00005819- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5820 in all operations, including splitdrive, split, etc. splitunc() now issues
5821 a PendingDeprecation warning.
5822
Eric Smith63376222009-05-05 14:04:18 +00005823- Issue #5920: For float.__format__, change the behavior with the
5824 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5825 to be like 'g' but with at least one decimal point and with a
5826 default precision of 12. Previously, the behavior the same but with
5827 a default precision of 6. This more closely matches str(), and
5828 reduces surprises when adding alignment flags to the empty
5829 presentation type. This also affects the new complex.__format__ in
5830 the same way.
5831
Martin v. Löwis011e8422009-05-05 04:43:17 +00005832- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5833
R. David Murrayb18500d2009-05-04 22:59:07 +00005834- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5835 shadowed by classtype's, even if it was None. property now
5836 inserts the __doc__ into the subclass instance __dict__.
5837
Antoine Pitrou244651a2009-05-04 18:56:13 +00005838- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5839 sequences. Patch by Nick Barnes and Victor Stinner.
5840
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005841- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005842
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005843- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5844 received a new method, detach(). detach() disconnects the underlying stream
5845 from the buffer or text IO and returns it.
5846
Mark Dickinson33841c32009-05-01 15:37:04 +00005847- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5848 floats with absolute value over 1e50. Also remove length
5849 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5850 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005851
Eric Smith741191f2009-05-06 13:08:15 +00005852- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005853 format(complex(1, 2./3), '.5') now produces a sensible result.
5854
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005855- Issue #5864: Fix empty format code formatting for floats so that it
5856 never gives more than the requested number of significant digits.
5857
Eric Smith6dc46f52009-04-27 20:39:49 +00005858- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5859 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5860
Eric Smithcc32a112009-04-26 21:35:14 +00005861- Issue #5835: Deprecate PyOS_ascii_formatd.
5862
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005863- Issue #4971: Fix titlecase for characters that are their own
5864 titlecase, but not their own uppercase.
5865
Benjamin Peterson193152c2009-04-25 01:08:45 +00005866- Issue #5283: Setting __class__ in __del__ caused a segfault.
5867
Mark Dickinsonad476da2009-04-23 19:14:16 +00005868- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5869 z involves nans, infs or negative zeros.
5870
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005871- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005872
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005873- Issue #1869 (and many duplicates): make round(x, n) correctly
5874 rounded for a float x, by using the decimal <-> binary conversions
5875 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5876 consistently agrees with format(x, '.2f').
5877
Benjamin Petersonae937c02009-04-18 20:54:08 +00005878- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5879 some builtin types.
5880
Eric Smith0923d1d2009-04-16 20:16:10 +00005881- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5882
Eric Smith35e84722009-04-16 20:21:28 +00005883- Issue #5515: str.format() type 'n' combined with commas and leading
5884 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005885
5886- Implement PEP 378, Format Specifier for Thousands Separator, for
5887 floats.
5888
Mark Dickinson3370cce2009-04-17 22:40:53 +00005889- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005890 1e11, not 1e12. This avoids printing 13 significant digits in
5891 situations where only 12 of them are correct. Example problem
5892 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5893 long time.)
5894
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005895- Issue #1580: On most platforms, use a 'short' float repr: for a
5896 finite float x, repr(x) now outputs a string based on the shortest
5897 sequence of decimal digits that rounds to x. Previous behaviour was
5898 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005899 Another minor difference is that the new repr switches to
5900 exponential notation at 1e16 instead of the previous 1e17; this
5901 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005902
5903 There's a new sys attribute sys.float_repr_style, which takes
5904 the value 'short' to indicate that we're using short float repr,
5905 and 'legacy' if the short float repr isn't available for one
5906 reason or another.
5907
5908 The float repr change involves incorporating David Gay's 'perfect
5909 rounding' code into the Python core (it's in Python/dtoa.c). As a
5910 secondary consequence, all string-to-float and float-to-string
5911 conversions (including all float formatting operations) will be
5912 correctly rounded on these platforms.
5913
Georg Brandl5f90d792010-08-01 22:31:05 +00005914 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005915 this change does not apply.
5916
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005917- Issue #5759: float() didn't call __float__ on str subclasses.
5918
Georg Brandlabc38772009-04-12 15:51:51 +00005919- The string.maketrans() function is deprecated; there is a new static method
5920 maketrans() on the bytes and bytearray classes. This removes confusion about
5921 the types string.maketrans() is supposed to work with, and mirrors the
5922 methods available on the str class.
5923
R. David Murraydc6da8a2009-04-09 22:16:43 +00005924- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5925 its clarity and its speed.
5926
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005927- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005928 to avoid compiler warnings.
5929
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005930- Issue #3739: The unicode-internal encoder now reports the number of characters
5931 consumed like any other encoder (instead of the number of bytes).

Martin v. Löwis403117a2009-05-24 19:19:17 +00005943- Issue #5311: bdist_msi can now build packages that do not depend on a
5944 specific Python version.
5945
Raymond Hettingereb816952009-05-29 01:22:18 +00005946- Issue #5150: IDLE's format menu now has an option to strip trailing

Benjamin Peterson8f76b492009-04-03 22:22:42 +00006068- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
6069
Benjamin Peterson7fe98532009-04-02 00:33:55 +00006070- Issue #5499: The 'c' code for argument parsing functions now only accepts a
6071 byte, and the 'C' code only accepts a unicode character.
6072
Georg Brandl406b3d82009-04-11 21:24:37 +00006073- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

Georg Brandlab6f2f62009-03-31 04:16:10 +00006078- Fix a segfault when running test_exceptions with coverage, caused by
6079 insufficient checks in accessors of Exception.__context__.
6080
Guido van Rossum0ad59d42009-03-30 22:01:35 +00006081- Issue #5604: non-ASCII characters in module name passed to
6082 imp.find_module() were converted to UTF-8 while the path is
6083 converted to the default filesystem encoding, causing nonsense.
6084
Benjamin Peterson09832742009-03-26 17:15:46 +00006085- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00006087- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
6088 the end sys.path, for compatibility with the system install of Python.
6089
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006090- Issue #4688: Add a heuristic so that tuples and dicts containing only
6091 untrackable objects are not tracked by the garbage collector. This can
6092 reduce the size of collections and therefore the garbage collection overhead
6093 on long-running programs, depending on their particular use of datatypes.
6094
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00006095- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

6097 are now between 50% and 150% faster.
6098
Mark Dickinsonbd792642009-03-18 20:06:12 +00006099- Issue #4258: Make it possible to use base 2**30 instead of base
6100 2**15 for the internal representation of integers, for performance
6101 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6102 --enable-big-digits option to configure, which overrides the
6103 default. Add sys.int_info structseq to provide information about
6104 the internal format.

Mark Dickinson87ec0852009-02-09 17:15:59 +00006216- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6217 it now forces its argument to double before testing for infinity.
6218
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006219- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6220 returns a non-number type.
6221
Benjamin Peterson87618552009-02-08 15:00:52 +00006222- Issue #5182: Removed memoryview.__str__.
6223
Mark Dickinsonc008a172009-02-01 13:59:22 +00006224- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6225 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006226 the type definition cmpfunc. The tp_compare slot has been renamed
6227 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006228
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006229- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006230 were suppressing all exceptions. These include list() and bytearray().
6231
Mark Dickinson1124e712009-01-28 21:25:58 +00006232- Issue #4707: round(x, n) now returns an integer if x is an integer.
6233 Previously it returned a float.
6234
Antoine Pitroub52ec782009-01-25 16:34:23 +00006235- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6236 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6237 evaluation loop is compiled with a new dispatch mechanism which gives
6238 speedups of up to 20%, depending on the system, on various benchmarks.
6239
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006240- Issue #4874: Most builtin decoders now reject unicode input.

6248 optional module state data.
6249
Mark Dickinson8055afd2009-01-17 10:04:45 +00006250- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006251 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006252
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006253- Issue #4935: The overflow checking code in the expandtabs() method common
6254 to str, bytes and bytearray could be optimized away by the compiler, letting
6255 the interpreter segfault instead of raising an error.
6256
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006257- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6258 __next__ method.
6259
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006260- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6261 function no longer attempt to call the __long__ slot to convert an object
6262 to an integer. Only the __int__ and __trunc__ slots are examined.
6263
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006264- Issue #4893: Use NT threading on CE.
6265

6267
Antoine Pitrouab868312009-01-10 15:40:25 +00006268- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6269 common cases are optimized thanks to a dedicated fast path and a moderate
6270 amount of loop unrolling.
6271
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006272- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6273 collecting the oldest generation) so that allocating lots of objects without
6274 destroying them does not show quadratic performance. Based on a proposal by
6275 Martin von Löwis at
6276 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6277
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006278- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006279 having been closed (for instance, a read() call could return some
6280 previously buffered data). Patch by Dmitry Vasiliev.
6281
Antoine Pitrou05608432009-01-09 18:53:14 +00006282- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6283 flag to work properly. Furthermore, when specifying -u, the text stdout
6284 and stderr streams have line-by-line buffering enabled (the default being
6285 to buffer arbitrary chunks of data).
6286
Raymond Hettinger35631532009-01-09 03:58:09 +00006287- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6288 instead of ints (reducing its size from 4 to 8 times thereby reducing
6289 Python's overall memory).
6290
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006291- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6292 an existing .py counterpart, override the co_filename attributes of all
6293 code objects if the original filename is obsolete (which can happen if the
6294 file has been renamed, moved, or if it is accessed through different paths).
6295 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6296
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006297- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6298 one byte. Also fixes the meaning of len() so that it returns the number of
6299 items, rather than the size in bytes.
6300
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006301- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6302
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006303- Issue #4747: When the terminal does not use utf-8, executing a script with
6304 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6305
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006306- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6307 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006308
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006309- Issue #3680: Reference cycles created through a dict, set or deque iterator
6310 did not get collected.
6311
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006312- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6313 where the tp_hash and tp_dict slots are both NULL.
6314
Georg Brandlccc47b62008-12-28 11:44:14 +00006315- Issue #4759: None is now allowed as the first argument of
6316 bytearray.translate(). It was always allowed for bytes.translate().
6317
Skip Montanaro80072cb2008-12-23 03:51:14 +00006318- Added test case to ensure attempts to read from a file opened for writing
6319 fail.
6320
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006321- Issue #3106: Speedup some comparisons (str/str and int/int).

6328 unreachable. Original patch by Neil Schemenauer.
6329

6331
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006332- Issue #2173: When getting device encoding, check that return value of
6333 nl_langinfo is not the empty string. This was causing silent build
6334 failures on OS X.
6335
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006336- Issue #4597: Fixed several opcodes that weren't always propagating
6337 exceptions.
6338
6339- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006340 context manager returns a value that cannot be converted to a bool.
6341
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006342- Issue #4445: Replace "sizeof(PyBytesObject)" with
6343 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6344 bytes instances. On a typical machine this saves 3 bytes of memory
6345 (on average) per allocation of a bytes instance.
6346
Christian Heimesa872de52008-12-05 08:26:55 +00006347- Issue #4533: File read operation was dreadfully slow due to a slowly
6348 growing read buffer. Fixed by using the same growth rate algorithm as
6349 Python 2.x.
6350
Antoine Pitrou5504e892008-12-06 21:27:53 +00006351- Issue #4509: Various issues surrounding resize of bytearray objects to
6352 which there are buffer exports (e.g. memoryview instances).
6353
Georg Brandlf9734072008-12-07 15:30:06 +00006354- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6355 method on file objects with closefd=False. The file descriptor is still
6356 kept open but the file object behaves like a closed file. The ``FileIO``
6357 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00006359- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00006366- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6367 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6368 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6369 of using the replace error handler in PyUnicode_DecodeUTF8().

Guilherme Polo2a998fa2009-06-21 17:40:07 +00006974- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6975 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6976 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6977 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00006979- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006980 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006981 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00006983- Issue #5083: New 'gui' resource for regrtest.
