Ned Deily657b2de2011-06-28 19:51:30 -0700196- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
197 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
198 interpreter process. This could cause failures in non-Distutils subprocesses
199 and was unreliable since tests or user programs could modify the interpreter
200 environment after Distutils set it. Instead, have Distutils set the the
201 deployment target only in the environment of each build subprocess. It is
202 still possible to globally override the default by setting
203 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
204 greater or equal to the default value, the value with which the interpreter
205 was built.

R. David Murrayb7deff12011-01-30 06:21:28 +0000877- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
878 files in binary mode, using the email package's binary support to parse
879 arbitrary email messages. StringIO and text file input is deprecated,
880 and string input fails early if non-ASCII characters are used, where
881 previously it would fail when the email was processed in a later step.
882
Nick Coghlan793ee1f2011-01-30 01:24:08 +0000883- Issue #10845: Mitigate the incompatibility between the multiprocessing
884 module on Windows and the use of package, zipfile or directory execution
885 by special casing main modules that actually *are* called __main__.py.
886
Éric Araujoac4e58e2011-01-29 20:32:11 +0000887- Issue #11045: Protect logging call against None argument.

Ned Deily5c2d3302011-01-29 19:10:26 +0000889- Issue #11052: Correct IDLE menu accelerators on Mac OS X for Save
890 commands.
891
Ned Deily806c9442011-01-29 18:43:56 +0000892- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
893 preventing a confusing hung appearance on OS X with the windows
894 obscured.
895
Ned Deily70063932011-01-29 18:29:01 +0000896- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the
897 menu accelerators for Open Module, Go to Line, and New Indent Width.
898 The accelerators still work but no longer appear in the menu items.
899
Victor Stinner80f75e62011-01-29 11:31:20 +0000900- Issue #10989: Fix a crash on SSLContext.load_verify_locations(None, True).
901
Raymond Hettinger8b5eb2f2011-01-27 00:06:54 +0000902- Issue #11020: Command-line pyclbr was broken because of missing 2-to-3
903 conversion.
904
R. David Murray7372a072011-01-26 21:21:32 +0000905- Issue #11019: Fixed BytesGenerator so that it correctly handles a Message
906 with a None body.
907
Raymond Hettingera63a3122011-01-26 20:34:14 +0000908- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
909 keyword-only argument. The preceding positional argument was deprecated,
910 so it made no sense to add filter as a positional argument.
911
Raymond Hettinger512d2cc2011-01-25 21:32:39 +0000912- Issue #11004: Repaired edge case in deque.count().
913
Ned Deily122539e2011-01-24 21:46:44 +0000914- Issue #10974: IDLE no longer crashes if its recent files list includes files
915 with non-ASCII characters in their path names.
916
Raymond Hettingerbf1d2bc2011-01-24 04:52:27 +0000917- Have hashlib.algorithms_available and hashlib.algorithms_guaranteed both
918 return sets instead of one returning a tuple and the other a frozenset.

923
Victor Stinnerf2e439f2011-01-23 00:11:58 +0000924- Issue #10955: zipimport uses ASCII encoding instead of cp437 to decode
Victor Stinner4ee65a92011-01-22 10:30:29 +0000925 filenames, at bootstrap, if the codec registry is not ready yet. It is still
926 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +0000927 for all file entries in the ZIP file.
Victor Stinner4ee65a92011-01-22 10:30:29 +0000928

935 a symbol named FSTAT.
936
Armin Ronacher8d96d772011-01-22 13:13:05 +0000937- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
938 encoding. This is the preferred encoding of PEP 3333 and the base encoding
939 of HTTP 1.1.
940
Armin Ronacher59531282011-01-22 13:44:22 +0000941- To match the behaviour of HTTP server, the HTTP client library now also
942 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
943 that for incoming headers which makes this behaviour now consistent in
944 both incoming and outgoing direction.
945
Steven Bethardb0270112011-01-24 21:02:50 +0000946- Issue #9509: argparse now properly handles IOErrors raised by
947 argparse.FileType.
Georg Brandl0c5036f2011-01-16 08:44:50 +0000948
Georg Brandld2f38572011-01-30 08:37:19 +0000949- Issue #10961: The new pydoc server now better handles exceptions raised
950 during request handling.
951

Georg Brandl255abdd2011-01-16 14:17:26 +0000980- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
981 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
982 translates newlines (\r\n => \n).
Victor Stinner89e34362011-01-07 18:47:22 +0000983
Martin v. Löwisc83bc3c2011-01-06 19:15:47 +0000984- Remove buffer API from stable ABI for now, see #10181.

988 (length bigger than 2^31-1 bytes).
989
Victor Stinnerdc555402011-01-04 13:15:39 +0000990- Issue #9015, #9611: FileIO.readinto(), FileIO.write(), os.write() and

1012 and a non-zero offset, and an attempt to read past the end of file is made
1013 (IndexError is raised instead). Patch by Ross Lagerwall.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001044- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001045 continuation line in the formatted value has no leading white space and looks
1046 like a header. Since Generator uses Header to format all headers, this check
1047 is made for all headers in any serialized message at serialization time. This
1048 provides protection against header injection attacks.

Georg Brandl255abdd2011-01-16 14:17:26 +00001058 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001059
Éric Araujof0ab5d62011-05-29 03:43:59 +02001060- email.header.Header was incorrectly encoding folding whitespace when

1068 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1069 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1070 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001699- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
1700 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001701 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001702 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001703 encoding and to encode command line arguments on this OS.

1708
Benjamin Peterson230b2062010-10-16 03:45:45 +00001709- Issue #9997: Don't let the name "top" have special significance in scope

2096 with a non-empty format string. This is an effort to future-proof user
2097 code. If a derived class does not currently implement __format__ but later
2098 adds its own __format__, it would most likely break user code that had
2099 supplied a format string. This will be changed to a DeprecationWaring in
2100 Python 3.3 and it will be an error in Python 3.4.

2104 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 +00002113- Issue #4617: Previously it was illegal to delete a name from the local
2114 namespace if it occurs as a free variable in a nested block. This limitation
2115 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2116
Georg Brandl27a28582010-10-10 09:49:21 +00002117- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2118 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2119 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2120 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002155- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002156 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002157 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002158 replacement for old handle_accept() and avoids the user to call accept()
2159 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00002183 retry the select() loop instead of bailing out. This is because select() can
2184 incorrectly report a socket as ready for reading (for example, if it received
2185 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002232 non-blocking mode: they return None when an operation would block (instead of

Georg Brandl27a28582010-10-10 09:49:21 +00002245- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2246 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002265- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002266 it possible for the user to create self-referencing ordered dictionaries which
2267 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002268 approach of using weakref proxies so that reference cycles never get created
2269 in the first place.
2270
Victor Stinnercb043522010-09-10 23:49:04 +00002271- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002275- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2276 environment variable to set the filesystem encoding at Python startup.
2277 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2278 reencode all filenames in all objects.

2289
Georg Brandl27a28582010-10-10 09:49:21 +00002290- Issue #9707: Rewritten reference implementation of threading.local which is
2291 friendlier towards reference cycles. This change is not normally visible
2292 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002294- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2295 still return the id of the parent process after it has exited. This process
2296 id may even have been reused by another unrelated process.
2297
Georg Brandl27a28582010-10-10 09:49:21 +00002298- Issue #9792: In case of connection failure, socket.create_connection() would
2299 swallow the exception and raise a new one, making it impossible to fetch the
2300 original errno, or to filter timeout errors. Now the original error is
2301 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002307- Updates to the random module:
2308
Georg Brandl27a28582010-10-10 09:49:21 +00002309 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002312 * Update the seed() method to use all of the bits in a string instead of just
2313 the hash value. This makes better use of the seed value and assures the
2314 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002315
Georg Brandl27a28582010-10-10 09:49:21 +00002316 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2317 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2318 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002319
2320 * Improved documentation of arguments to randrange(). Issue #9379.

2341 guaranteed to exist in all Python implementations and the names of hash
2342 algorithms available in the current process.

2471 return characters from the full Unicode range, even on narrow unicode builds
2472 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

2474 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00002500- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2501 use PyUnicode_FromFormatV() to format the warning message.

2509 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002510
Georg Brandl649971e2010-09-05 17:06:50 +00002511- Issue #9416: Fix some issues with complex formatting where the output with no
2512 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002513
2514 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

3080 parsing certain long numeric strings corresponding to subnormal values, (3) a
3081 memory leak for some values large enough to cause overflow, and (4) a number
3082 of flaws that could lead to incorrectly rounded results.

Georg Brandl62069d32010-07-31 08:56:11 +00003777- Issue #8257: The Decimal construct now accepts a float instance directly,
3778 converting that float to a Decimal of equal value:

Georg Brandl62069d32010-07-31 08:56:11 +00003786- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3787 InvalidOperation instead of returning False. (Comparisons involving a quiet
3788 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3789 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00003791- Issue #2531: Comparison operations between floats and Decimal instances now
3792 return a result based on the numeric values of the operands; previously they
3793 returned an arbitrary result based on the relative ordering of id(float) and
3794 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3795 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003796
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003797- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00003799- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003800 argument `-` which tells it to read files to compile from stdin. Each line is
3801 read on demand and the named file is compiled immediately. (Original patch by
3802 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00003808- Comparisons using one of <, <=, >, >= between a complex instance and a
3809 Fractions instance now raise TypeError instead of returning True/False. This
3810 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3811 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003854- The internals of the subprocess module on POSIX systems have been replaced by
3855 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3856 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003857
Georg Brandl62069d32010-07-31 08:56:11 +00003858- subprocess.Popen now has restore_signals and start_new_session features. The
3859 default of restore_signals=True is a new behavior compared to earlier Python
3860 versions. This means that signals such as SIGPIPE are not ignored by default
3861 in subprocesses launched by Python (Issue #1652).

3948 position when calling `truncate()`. It would previously change the file
3949 position to the given argument, which goes against the tradition of

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004354- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004355 compared to other unix systems. In particular, os.getgroups() does not reflect
4356 any changes made using os.setgroups() but basicly always returns the same
4357 information as the id command. os.getgroups() can now return more than 16
4358 groups on MacOSX.

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005001*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005002
5003Core and Builtins
5004-----------------
5005
Mark Dickinson865e01a2009-05-07 16:37:01 +00005006- Issue #5914: Add new C API function PyOS_string_to_double, and
5007 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5008
Eric Smith741191f2009-05-06 13:08:15 +00005009- Issue #3382: float.__format__, complex.__format__, and %-formatting
5010 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5011 affects nan -> NAN and inf -> INF.
5012
Mark Hammond5a607a32009-05-06 08:04:54 +00005013- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5014 in all operations, including splitdrive, split, etc. splitunc() now issues
5015 a PendingDeprecation warning.
5016
Eric Smith63376222009-05-05 14:04:18 +00005017- Issue #5920: For float.__format__, change the behavior with the
5018 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5019 to be like 'g' but with at least one decimal point and with a
5020 default precision of 12. Previously, the behavior the same but with
5021 a default precision of 6. This more closely matches str(), and
5022 reduces surprises when adding alignment flags to the empty
5023 presentation type. This also affects the new complex.__format__ in
5024 the same way.
5025
Martin v. Löwis011e8422009-05-05 04:43:17 +00005026- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5027
R. David Murrayb18500d2009-05-04 22:59:07 +00005028- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5029 shadowed by classtype's, even if it was None. property now
5030 inserts the __doc__ into the subclass instance __dict__.
5031
Antoine Pitrou244651a2009-05-04 18:56:13 +00005032- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5033 sequences. Patch by Nick Barnes and Victor Stinner.
5034
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005035- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005036
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005037- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5038 received a new method, detach(). detach() disconnects the underlying stream
5039 from the buffer or text IO and returns it.
5040
Mark Dickinson33841c32009-05-01 15:37:04 +00005041- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5042 floats with absolute value over 1e50. Also remove length
5043 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5044 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005045
Eric Smith741191f2009-05-06 13:08:15 +00005046- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005047 format(complex(1, 2./3), '.5') now produces a sensible result.
5048
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005049- Issue #5864: Fix empty format code formatting for floats so that it
5050 never gives more than the requested number of significant digits.
5051
Eric Smith6dc46f52009-04-27 20:39:49 +00005052- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5053 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5054
Eric Smithcc32a112009-04-26 21:35:14 +00005055- Issue #5835: Deprecate PyOS_ascii_formatd.
5056
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005057- Issue #4971: Fix titlecase for characters that are their own
5058 titlecase, but not their own uppercase.
5059
Benjamin Peterson193152c2009-04-25 01:08:45 +00005060- Issue #5283: Setting __class__ in __del__ caused a segfault.
5061
Mark Dickinsonad476da2009-04-23 19:14:16 +00005062- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5063 z involves nans, infs or negative zeros.
5064
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005065- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005066
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005067- Issue #1869 (and many duplicates): make round(x, n) correctly
5068 rounded for a float x, by using the decimal <-> binary conversions
5069 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5070 consistently agrees with format(x, '.2f').
5071
Benjamin Petersonae937c02009-04-18 20:54:08 +00005072- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5073 some builtin types.
5074
Eric Smith0923d1d2009-04-16 20:16:10 +00005075- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5076
Eric Smith35e84722009-04-16 20:21:28 +00005077- Issue #5515: str.format() type 'n' combined with commas and leading
5078 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005079
5080- Implement PEP 378, Format Specifier for Thousands Separator, for
5081 floats.
5082
Mark Dickinson3370cce2009-04-17 22:40:53 +00005083- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005084 1e11, not 1e12. This avoids printing 13 significant digits in
5085 situations where only 12 of them are correct. Example problem
5086 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5087 long time.)
5088
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005089- Issue #1580: On most platforms, use a 'short' float repr: for a
5090 finite float x, repr(x) now outputs a string based on the shortest
5091 sequence of decimal digits that rounds to x. Previous behaviour was
5092 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005093 Another minor difference is that the new repr switches to
5094 exponential notation at 1e16 instead of the previous 1e17; this
5095 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005096
5097 There's a new sys attribute sys.float_repr_style, which takes
5098 the value 'short' to indicate that we're using short float repr,
5099 and 'legacy' if the short float repr isn't available for one
5100 reason or another.
5101
5102 The float repr change involves incorporating David Gay's 'perfect
5103 rounding' code into the Python core (it's in Python/dtoa.c). As a
5104 secondary consequence, all string-to-float and float-to-string
5105 conversions (including all float formatting operations) will be
5106 correctly rounded on these platforms.
5107
Georg Brandl5f90d792010-08-01 22:31:05 +00005108 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005109 this change does not apply.
5110
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005111- Issue #5759: float() didn't call __float__ on str subclasses.
5112
Georg Brandlabc38772009-04-12 15:51:51 +00005113- The string.maketrans() function is deprecated; there is a new static method
5114 maketrans() on the bytes and bytearray classes. This removes confusion about
5115 the types string.maketrans() is supposed to work with, and mirrors the
5116 methods available on the str class.
5117
R. David Murraydc6da8a2009-04-09 22:16:43 +00005118- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5119 its clarity and its speed.
5120
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005121- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005122 to avoid compiler warnings.
5123
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005124- Issue #3739: The unicode-internal encoder now reports the number of characters
5125 consumed like any other encoder (instead of the number of bytes).

Martin v. Löwis403117a2009-05-24 19:19:17 +00005137- Issue #5311: bdist_msi can now build packages that do not depend on a

5139
Raymond Hettingereb816952009-05-29 01:22:18 +00005140- Issue #5150: IDLE's format menu now has an option to strip trailing
5141 whitespace.
5142
Vinay Sajipaffbd872009-06-11 10:11:47 +00005143- Issue #5940: distutils.command.build_clib.check_library_list was not doing

5206 results in a handle_expt_event call, not handle_read_event, and POLLERR
5207 and POLLNVAL now call handle_close, not handle_expt_event. Also,
5208 dispatcher now has an 'ignore_log_types' attribute for suppressing

Benjamin Peterson8f76b492009-04-03 22:22:42 +00005262- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
5263
Benjamin Peterson7fe98532009-04-02 00:33:55 +00005264- Issue #5499: The 'c' code for argument parsing functions now only accepts a
5265 byte, and the 'C' code only accepts a unicode character.
5266
Georg Brandl406b3d82009-04-11 21:24:37 +00005267- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
5268 when hitting the recursion limit under certain circumstances.
5269
Brett Cannon0759dd62009-04-01 18:13:07 +00005270- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.

5283
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005284- Issue #4688: Add a heuristic so that tuples and dicts containing only
5285 untrackable objects are not tracked by the garbage collector. This can
5286 reduce the size of collections and therefore the garbage collection overhead
5287 on long-running programs, depending on their particular use of datatypes.

Mark Dickinsonbd792642009-03-18 20:06:12 +00005293- Issue #4258: Make it possible to use base 2**30 instead of base
5294 2**15 for the internal representation of integers, for performance
5295 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5296 --enable-big-digits option to configure, which overrides the
5297 default. Add sys.int_info structseq to provide information about
5298 the internal format.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005410- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5411 it now forces its argument to double before testing for infinity.
5412
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005413- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5414 returns a non-number type.
5415
Benjamin Peterson87618552009-02-08 15:00:52 +00005416- Issue #5182: Removed memoryview.__str__.
5417
Mark Dickinsonc008a172009-02-01 13:59:22 +00005418- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5419 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005420 the type definition cmpfunc. The tp_compare slot has been renamed
5421 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005422
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005423- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005424 were suppressing all exceptions. These include list() and bytearray().
5425
Mark Dickinson1124e712009-01-28 21:25:58 +00005426- Issue #4707: round(x, n) now returns an integer if x is an integer.
5427 Previously it returned a float.
5428
Antoine Pitroub52ec782009-01-25 16:34:23 +00005429- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5430 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5431 evaluation loop is compiled with a new dispatch mechanism which gives
5432 speedups of up to 20%, depending on the system, on various benchmarks.
5433
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005434- Issue #4874: Most builtin decoders now reject unicode input.

5442 optional module state data.
5443
Mark Dickinson8055afd2009-01-17 10:04:45 +00005444- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005445 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005446
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005447- Issue #4935: The overflow checking code in the expandtabs() method common
5448 to str, bytes and bytearray could be optimized away by the compiler, letting
5449 the interpreter segfault instead of raising an error.
5450
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005451- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5452 __next__ method.
5453
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005454- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5455 function no longer attempt to call the __long__ slot to convert an object
5456 to an integer. Only the __int__ and __trunc__ slots are examined.
5457
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005458- Issue #4893: Use NT threading on CE.

5461
Antoine Pitrouab868312009-01-10 15:40:25 +00005462- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5463 common cases are optimized thanks to a dedicated fast path and a moderate
5464 amount of loop unrolling.
5465
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005466- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5467 collecting the oldest generation) so that allocating lots of objects without
5468 destroying them does not show quadratic performance. Based on a proposal by
5469 Martin von Löwis at
5470 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5471
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005472- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005473 having been closed (for instance, a read() call could return some
5474 previously buffered data). Patch by Dmitry Vasiliev.
5475
Antoine Pitrou05608432009-01-09 18:53:14 +00005476- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5477 flag to work properly. Furthermore, when specifying -u, the text stdout
5478 and stderr streams have line-by-line buffering enabled (the default being
5479 to buffer arbitrary chunks of data).
5480
Raymond Hettinger35631532009-01-09 03:58:09 +00005481- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5482 instead of ints (reducing its size from 4 to 8 times thereby reducing
5483 Python's overall memory).
5484
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005485- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5486 an existing .py counterpart, override the co_filename attributes of all
5487 code objects if the original filename is obsolete (which can happen if the
5488 file has been renamed, moved, or if it is accessed through different paths).
5489 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5490
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005491- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5492 one byte. Also fixes the meaning of len() so that it returns the number of
5493 items, rather than the size in bytes.
5494
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005495- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5496
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005497- Issue #4747: When the terminal does not use utf-8, executing a script with
5498 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5499
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005500- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5501 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005502
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005503- Issue #3680: Reference cycles created through a dict, set or deque iterator
5504 did not get collected.
5505
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005506- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5507 where the tp_hash and tp_dict slots are both NULL.
5508
Georg Brandlccc47b62008-12-28 11:44:14 +00005509- Issue #4759: None is now allowed as the first argument of
5510 bytearray.translate(). It was always allowed for bytes.translate().
5511
Skip Montanaro80072cb2008-12-23 03:51:14 +00005512- Added test case to ensure attempts to read from a file opened for writing
5513 fail.
5514
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005515- Issue #3106: Speedup some comparisons (str/str and int/int).

5525
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005526- Issue #2173: When getting device encoding, check that return value of
5527 nl_langinfo is not the empty string. This was causing silent build
5528 failures on OS X.
5529
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005530- Issue #4597: Fixed several opcodes that weren't always propagating
5531 exceptions.
5532
5533- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005534 context manager returns a value that cannot be converted to a bool.
5535
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005536- Issue #4445: Replace "sizeof(PyBytesObject)" with
5537 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5538 bytes instances. On a typical machine this saves 3 bytes of memory
5539 (on average) per allocation of a bytes instance.
5540
Christian Heimesa872de52008-12-05 08:26:55 +00005541- Issue #4533: File read operation was dreadfully slow due to a slowly
5542 growing read buffer. Fixed by using the same growth rate algorithm as
5543 Python 2.x.
5544
Antoine Pitrou5504e892008-12-06 21:27:53 +00005545- Issue #4509: Various issues surrounding resize of bytearray objects to
5546 which there are buffer exports (e.g. memoryview instances).
5547
Georg Brandlf9734072008-12-07 15:30:06 +00005548- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5549 method on file objects with closefd=False. The file descriptor is still
5550 kept open but the file object behaves like a closed file. The ``FileIO``
5551 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00005553- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5554 larger than 1.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00005560- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5561 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5562 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5563 of using the replace error handler in PyUnicode_DecodeUTF8().

Guilherme Polo2a998fa2009-06-21 17:40:07 +00006168- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6169 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6170 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6171 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00006173- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006174 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006175 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00006177- Issue #5083: New 'gui' resource for regrtest.
