Ned Deily657b2de2011-06-28 19:51:30 -0700193- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
194 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
195 interpreter process. This could cause failures in non-Distutils subprocesses
196 and was unreliable since tests or user programs could modify the interpreter
197 environment after Distutils set it. Instead, have Distutils set the the
198 deployment target only in the environment of each build subprocess. It is
199 still possible to globally override the default by setting
200 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
201 greater or equal to the default value, the value with which the interpreter
202 was built.

R. David Murrayb7deff12011-01-30 06:21:28 +0000874- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
875 files in binary mode, using the email package's binary support to parse
876 arbitrary email messages. StringIO and text file input is deprecated,
877 and string input fails early if non-ASCII characters are used, where
878 previously it would fail when the email was processed in a later step.
879
Nick Coghlan793ee1f2011-01-30 01:24:08 +0000880- Issue #10845: Mitigate the incompatibility between the multiprocessing
881 module on Windows and the use of package, zipfile or directory execution
882 by special casing main modules that actually *are* called __main__.py.
883
Éric Araujoac4e58e2011-01-29 20:32:11 +0000884- Issue #11045: Protect logging call against None argument.

887 commands.
888
Ned Deily806c9442011-01-29 18:43:56 +0000889- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
890 preventing a confusing hung appearance on OS X with the windows
891 obscured.
892
Ned Deily70063932011-01-29 18:29:01 +0000893- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the
894 menu accelerators for Open Module, Go to Line, and New Indent Width.
895 The accelerators still work but no longer appear in the menu items.
896

898
Raymond Hettinger8b5eb2f2011-01-27 00:06:54 +0000899- Issue #11020: Command-line pyclbr was broken because of missing 2-to-3
900 conversion.

R. David Murray7372a072011-01-26 21:21:32 +0000902- Issue #11019: Fixed BytesGenerator so that it correctly handles a Message
903 with a None body.
904
Raymond Hettingera63a3122011-01-26 20:34:14 +0000905- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
906 keyword-only argument. The preceding positional argument was deprecated,
907 so it made no sense to add filter as a positional argument.
908
Raymond Hettinger512d2cc2011-01-25 21:32:39 +0000909- Issue #11004: Repaired edge case in deque.count().
910
Ned Deily122539e2011-01-24 21:46:44 +0000911- Issue #10974: IDLE no longer crashes if its recent files list includes files
912 with non-ASCII characters in their path names.
913
Raymond Hettingerbf1d2bc2011-01-24 04:52:27 +0000914- Have hashlib.algorithms_available and hashlib.algorithms_guaranteed both
915 return sets instead of one returning a tuple and the other a frozenset.

920
Victor Stinnerf2e439f2011-01-23 00:11:58 +0000921- Issue #10955: zipimport uses ASCII encoding instead of cp437 to decode
Victor Stinner4ee65a92011-01-22 10:30:29 +0000922 filenames, at bootstrap, if the codec registry is not ready yet. It is still
923 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +0000924 for all file entries in the ZIP file.
Victor Stinner4ee65a92011-01-22 10:30:29 +0000925

932 a symbol named FSTAT.
933
Armin Ronacher8d96d772011-01-22 13:13:05 +0000934- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
935 encoding. This is the preferred encoding of PEP 3333 and the base encoding
936 of HTTP 1.1.
937
Armin Ronacher59531282011-01-22 13:44:22 +0000938- To match the behaviour of HTTP server, the HTTP client library now also
939 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
940 that for incoming headers which makes this behaviour now consistent in
941 both incoming and outgoing direction.
942
Steven Bethardb0270112011-01-24 21:02:50 +0000943- Issue #9509: argparse now properly handles IOErrors raised by

Georg Brandl255abdd2011-01-16 14:17:26 +0000977- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
978 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
979 translates newlines (\r\n => \n).

1009 and a non-zero offset, and an attempt to read past the end of file is made
1010 (IndexError is raised instead). Patch by Ross Lagerwall.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001041- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001042 continuation line in the formatted value has no leading white space and looks
1043 like a header. Since Generator uses Header to format all headers, this check
1044 is made for all headers in any serialized message at serialization time. This
1045 provides protection against header injection attacks.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001696- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
1697 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001698 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001699 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001700 encoding and to encode command line arguments on this OS.

1703 filenames encoded to the filesystem encoding with the surrogateescape error

1705
Benjamin Peterson230b2062010-10-16 03:45:45 +00001706- Issue #9997: Don't let the name "top" have special significance in scope

2093 with a non-empty format string. This is an effort to future-proof user
2094 code. If a derived class does not currently implement __format__ but later
2095 adds its own __format__, it would most likely break user code that had
2096 supplied a format string. This will be changed to a DeprecationWaring in
2097 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002099- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

2101 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

2104 functions from the libc caused the methods .upper() and lower() to become
2105 locale aware and created subtly wrong results.
2106
Georg Brandl27a28582010-10-10 09:49:21 +00002107- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Victor Stinner1205f272010-09-11 00:54:47 +00002109
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002110- Issue #4617: Previously it was illegal to delete a name from the local
2111 namespace if it occurs as a free variable in a nested block. This limitation
2112 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2113
Georg Brandl27a28582010-10-10 09:49:21 +00002114- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2115 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2116 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2117 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002152- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002153 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002154 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002155 replacement for old handle_accept() and avoids the user to call accept()
2156 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00002180 retry the select() loop instead of bailing out. This is because select() can
2181 incorrectly report a socket as ready for reading (for example, if it received
2182 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002229 non-blocking mode: they return None when an operation would block (instead of

Georg Brandl27a28582010-10-10 09:49:21 +00002242- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2243 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002262- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002263 it possible for the user to create self-referencing ordered dictionaries which
2264 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002265 approach of using weakref proxies so that reference cycles never get created
2266 in the first place.
2267
Victor Stinnercb043522010-09-10 23:49:04 +00002268- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002272- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2273 environment variable to set the filesystem encoding at Python startup.
2274 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2275 reencode all filenames in all objects.

2286
Georg Brandl27a28582010-10-10 09:49:21 +00002287- Issue #9707: Rewritten reference implementation of threading.local which is
2288 friendlier towards reference cycles. This change is not normally visible
2289 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002291- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2292 still return the id of the parent process after it has exited. This process
2293 id may even have been reused by another unrelated process.
2294
Georg Brandl27a28582010-10-10 09:49:21 +00002295- Issue #9792: In case of connection failure, socket.create_connection() would
2296 swallow the exception and raise a new one, making it impossible to fetch the
2297 original errno, or to filter timeout errors. Now the original error is
2298 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002304- Updates to the random module:
2305
Georg Brandl27a28582010-10-10 09:49:21 +00002306 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002309 * Update the seed() method to use all of the bits in a string instead of just
2310 the hash value. This makes better use of the seed value and assures the
2311 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002312
Georg Brandl27a28582010-10-10 09:49:21 +00002313 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2314 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2315 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002316
2317 * Improved documentation of arguments to randrange(). Issue #9379.

2338 guaranteed to exist in all Python implementations and the names of hash
2339 algorithms available in the current process.

2468 return characters from the full Unicode range, even on narrow unicode builds
2469 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2470 in Python is that unicodedata.numeric() now returns the correct value for
2471 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00002497- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2498 use PyUnicode_FromFormatV() to format the warning message.

2506 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002507
Georg Brandl649971e2010-09-05 17:06:50 +00002508- Issue #9416: Fix some issues with complex formatting where the output with no
2509 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002510
2511 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2512 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3077 parsing certain long numeric strings corresponding to subnormal values, (3) a
3078 memory leak for some values large enough to cause overflow, and (4) a number
3079 of flaws that could lead to incorrectly rounded results.

Georg Brandl62069d32010-07-31 08:56:11 +00003774- Issue #8257: The Decimal construct now accepts a float instance directly,
3775 converting that float to a Decimal of equal value:

Georg Brandl62069d32010-07-31 08:56:11 +00003783- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3784 InvalidOperation instead of returning False. (Comparisons involving a quiet
3785 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3786 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00003788- Issue #2531: Comparison operations between floats and Decimal instances now
3789 return a result based on the numeric values of the operands; previously they
3790 returned an arbitrary result based on the relative ordering of id(float) and
3791 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3792 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003793
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003794- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00003796- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003797 argument `-` which tells it to read files to compile from stdin. Each line is
3798 read on demand and the named file is compiled immediately. (Original patch by
3799 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00003805- Comparisons using one of <, <=, >, >= between a complex instance and a
3806 Fractions instance now raise TypeError instead of returning True/False. This
3807 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3808 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003851- The internals of the subprocess module on POSIX systems have been replaced by
3852 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3853 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003854
Georg Brandl62069d32010-07-31 08:56:11 +00003855- subprocess.Popen now has restore_signals and start_new_session features. The
3856 default of restore_signals=True is a new behavior compared to earlier Python
3857 versions. This means that signals such as SIGPIPE are not ignored by default
3858 in subprocesses launched by Python (Issue #1652).

3945 position when calling `truncate()`. It would previously change the file
3946 position to the given argument, which goes against the tradition of

3951 archive. The new implementation is significantly faster and can be wrapped in
3952 a :class:`io.BufferedReader` object for more speedups. It also solves an
3953 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004351- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004352 compared to other unix systems. In particular, os.getgroups() does not reflect
4353 any changes made using os.setgroups() but basicly always returns the same
4354 information as the id command. os.getgroups() can now return more than 16
4355 groups on MacOSX.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00004999
5000Core and Builtins
5001-----------------
5002
Mark Dickinson865e01a2009-05-07 16:37:01 +00005003- Issue #5914: Add new C API function PyOS_string_to_double, and
5004 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5005
Eric Smith741191f2009-05-06 13:08:15 +00005006- Issue #3382: float.__format__, complex.__format__, and %-formatting
5007 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5008 affects nan -> NAN and inf -> INF.
5009
Mark Hammond5a607a32009-05-06 08:04:54 +00005010- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5011 in all operations, including splitdrive, split, etc. splitunc() now issues
5012 a PendingDeprecation warning.
5013
Eric Smith63376222009-05-05 14:04:18 +00005014- Issue #5920: For float.__format__, change the behavior with the
5015 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5016 to be like 'g' but with at least one decimal point and with a
5017 default precision of 12. Previously, the behavior the same but with
5018 a default precision of 6. This more closely matches str(), and
5019 reduces surprises when adding alignment flags to the empty
5020 presentation type. This also affects the new complex.__format__ in
5021 the same way.
5022
Martin v. Löwis011e8422009-05-05 04:43:17 +00005023- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5024
R. David Murrayb18500d2009-05-04 22:59:07 +00005025- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5026 shadowed by classtype's, even if it was None. property now
5027 inserts the __doc__ into the subclass instance __dict__.
5028
Antoine Pitrou244651a2009-05-04 18:56:13 +00005029- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5030 sequences. Patch by Nick Barnes and Victor Stinner.
5031
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005032- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005033
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005034- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5035 received a new method, detach(). detach() disconnects the underlying stream
5036 from the buffer or text IO and returns it.
5037
Mark Dickinson33841c32009-05-01 15:37:04 +00005038- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5039 floats with absolute value over 1e50. Also remove length
5040 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5041 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005042
Eric Smith741191f2009-05-06 13:08:15 +00005043- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005044 format(complex(1, 2./3), '.5') now produces a sensible result.
5045
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005046- Issue #5864: Fix empty format code formatting for floats so that it
5047 never gives more than the requested number of significant digits.
5048
Eric Smith6dc46f52009-04-27 20:39:49 +00005049- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5050 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5051
Eric Smithcc32a112009-04-26 21:35:14 +00005052- Issue #5835: Deprecate PyOS_ascii_formatd.
5053
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005054- Issue #4971: Fix titlecase for characters that are their own
5055 titlecase, but not their own uppercase.
5056
Benjamin Peterson193152c2009-04-25 01:08:45 +00005057- Issue #5283: Setting __class__ in __del__ caused a segfault.
5058
Mark Dickinsonad476da2009-04-23 19:14:16 +00005059- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5060 z involves nans, infs or negative zeros.
5061
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005062- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005063
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005064- Issue #1869 (and many duplicates): make round(x, n) correctly
5065 rounded for a float x, by using the decimal <-> binary conversions
5066 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5067 consistently agrees with format(x, '.2f').
5068
Benjamin Petersonae937c02009-04-18 20:54:08 +00005069- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5070 some builtin types.
5071
Eric Smith0923d1d2009-04-16 20:16:10 +00005072- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5073
Eric Smith35e84722009-04-16 20:21:28 +00005074- Issue #5515: str.format() type 'n' combined with commas and leading
5075 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005076
5077- Implement PEP 378, Format Specifier for Thousands Separator, for
5078 floats.
5079
Mark Dickinson3370cce2009-04-17 22:40:53 +00005080- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005081 1e11, not 1e12. This avoids printing 13 significant digits in
5082 situations where only 12 of them are correct. Example problem
5083 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5084 long time.)
5085
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005086- Issue #1580: On most platforms, use a 'short' float repr: for a
5087 finite float x, repr(x) now outputs a string based on the shortest
5088 sequence of decimal digits that rounds to x. Previous behaviour was
5089 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005090 Another minor difference is that the new repr switches to
5091 exponential notation at 1e16 instead of the previous 1e17; this
5092 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005093
5094 There's a new sys attribute sys.float_repr_style, which takes
5095 the value 'short' to indicate that we're using short float repr,
5096 and 'legacy' if the short float repr isn't available for one
5097 reason or another.
5098
5099 The float repr change involves incorporating David Gay's 'perfect
5100 rounding' code into the Python core (it's in Python/dtoa.c). As a
5101 secondary consequence, all string-to-float and float-to-string
5102 conversions (including all float formatting operations) will be
5103 correctly rounded on these platforms.
5104
Georg Brandl5f90d792010-08-01 22:31:05 +00005105 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005106 this change does not apply.
5107
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005108- Issue #5759: float() didn't call __float__ on str subclasses.
5109
Georg Brandlabc38772009-04-12 15:51:51 +00005110- The string.maketrans() function is deprecated; there is a new static method
5111 maketrans() on the bytes and bytearray classes. This removes confusion about
5112 the types string.maketrans() is supposed to work with, and mirrors the
5113 methods available on the str class.
5114
R. David Murraydc6da8a2009-04-09 22:16:43 +00005115- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5116 its clarity and its speed.
5117
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005118- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005119 to avoid compiler warnings.
5120
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005121- Issue #3739: The unicode-internal encoder now reports the number of characters
5122 consumed like any other encoder (instead of the number of bytes).

5136
Raymond Hettingereb816952009-05-29 01:22:18 +00005137- Issue #5150: IDLE's format menu now has an option to strip trailing
5138 whitespace.
5139
Vinay Sajipaffbd872009-06-11 10:11:47 +00005140- Issue #5940: distutils.command.build_clib.check_library_list was not doing

5203 results in a handle_expt_event call, not handle_read_event, and POLLERR
5204 and POLLNVAL now call handle_close, not handle_expt_event. Also,
5205 dispatcher now has an 'ignore_log_types' attribute for suppressing

5260
Benjamin Peterson7fe98532009-04-02 00:33:55 +00005261- Issue #5499: The 'c' code for argument parsing functions now only accepts a
5262 byte, and the 'C' code only accepts a unicode character.
5263
Georg Brandl406b3d82009-04-11 21:24:37 +00005264- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
5265 when hitting the recursion limit under certain circumstances.
5266
Brett Cannon0759dd62009-04-01 18:13:07 +00005267- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.

5280
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005281- Issue #4688: Add a heuristic so that tuples and dicts containing only
5282 untrackable objects are not tracked by the garbage collector. This can
5283 reduce the size of collections and therefore the garbage collection overhead
5284 on long-running programs, depending on their particular use of datatypes.
5285
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005286- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

Mark Dickinsonbd792642009-03-18 20:06:12 +00005290- Issue #4258: Make it possible to use base 2**30 instead of base
5291 2**15 for the internal representation of integers, for performance
5292 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5293 --enable-big-digits option to configure, which overrides the
5294 default. Add sys.int_info structseq to provide information about
5295 the internal format.

5405 rotating the object pointer by 4 bits to the right.
5406
Mark Dickinson87ec0852009-02-09 17:15:59 +00005407- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5408 it now forces its argument to double before testing for infinity.
5409
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005410- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5411 returns a non-number type.
5412
Benjamin Peterson87618552009-02-08 15:00:52 +00005413- Issue #5182: Removed memoryview.__str__.
5414
Mark Dickinsonc008a172009-02-01 13:59:22 +00005415- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5416 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005417 the type definition cmpfunc. The tp_compare slot has been renamed
5418 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005419
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005420- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005421 were suppressing all exceptions. These include list() and bytearray().
5422
Mark Dickinson1124e712009-01-28 21:25:58 +00005423- Issue #4707: round(x, n) now returns an integer if x is an integer.
5424 Previously it returned a float.
5425
Antoine Pitroub52ec782009-01-25 16:34:23 +00005426- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5427 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5428 evaluation loop is compiled with a new dispatch mechanism which gives
5429 speedups of up to 20%, depending on the system, on various benchmarks.
5430
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005431- Issue #4874: Most builtin decoders now reject unicode input.

5439 optional module state data.
5440
Mark Dickinson8055afd2009-01-17 10:04:45 +00005441- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005442 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005443
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005444- Issue #4935: The overflow checking code in the expandtabs() method common
5445 to str, bytes and bytearray could be optimized away by the compiler, letting
5446 the interpreter segfault instead of raising an error.
5447
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005448- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5449 __next__ method.
5450
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005451- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5452 function no longer attempt to call the __long__ slot to convert an object
5453 to an integer. Only the __int__ and __trunc__ slots are examined.
5454
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005455- Issue #4893: Use NT threading on CE.
5456

5458
Antoine Pitrouab868312009-01-10 15:40:25 +00005459- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5460 common cases are optimized thanks to a dedicated fast path and a moderate
5461 amount of loop unrolling.
5462
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005463- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5464 collecting the oldest generation) so that allocating lots of objects without
5465 destroying them does not show quadratic performance. Based on a proposal by
5466 Martin von Löwis at
5467 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5468
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005469- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005470 having been closed (for instance, a read() call could return some
5471 previously buffered data). Patch by Dmitry Vasiliev.
5472
Antoine Pitrou05608432009-01-09 18:53:14 +00005473- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5474 flag to work properly. Furthermore, when specifying -u, the text stdout
5475 and stderr streams have line-by-line buffering enabled (the default being
5476 to buffer arbitrary chunks of data).
5477
Raymond Hettinger35631532009-01-09 03:58:09 +00005478- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5479 instead of ints (reducing its size from 4 to 8 times thereby reducing
5480 Python's overall memory).
5481
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005482- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5483 an existing .py counterpart, override the co_filename attributes of all
5484 code objects if the original filename is obsolete (which can happen if the
5485 file has been renamed, moved, or if it is accessed through different paths).
5486 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5487
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005488- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5489 one byte. Also fixes the meaning of len() so that it returns the number of
5490 items, rather than the size in bytes.
5491
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005492- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5493
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005494- Issue #4747: When the terminal does not use utf-8, executing a script with
5495 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5496
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005497- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5498 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005499
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005500- Issue #3680: Reference cycles created through a dict, set or deque iterator
5501 did not get collected.
5502
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005503- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5504 where the tp_hash and tp_dict slots are both NULL.
5505
Georg Brandlccc47b62008-12-28 11:44:14 +00005506- Issue #4759: None is now allowed as the first argument of
5507 bytearray.translate(). It was always allowed for bytes.translate().
5508
Skip Montanaro80072cb2008-12-23 03:51:14 +00005509- Added test case to ensure attempts to read from a file opened for writing
5510 fail.
5511
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005512- Issue #3106: Speedup some comparisons (str/str and int/int).

Mark Dickinsonda2706b2008-12-11 18:03:03 +00005523- Issue #2173: When getting device encoding, check that return value of
5524 nl_langinfo is not the empty string. This was causing silent build
5525 failures on OS X.
5526
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005527- Issue #4597: Fixed several opcodes that weren't always propagating
5528 exceptions.
5529
5530- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005531 context manager returns a value that cannot be converted to a bool.
5532
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005533- Issue #4445: Replace "sizeof(PyBytesObject)" with
5534 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5535 bytes instances. On a typical machine this saves 3 bytes of memory
5536 (on average) per allocation of a bytes instance.
5537
Christian Heimesa872de52008-12-05 08:26:55 +00005538- Issue #4533: File read operation was dreadfully slow due to a slowly
5539 growing read buffer. Fixed by using the same growth rate algorithm as
5540 Python 2.x.
5541
Antoine Pitrou5504e892008-12-06 21:27:53 +00005542- Issue #4509: Various issues surrounding resize of bytearray objects to
5543 which there are buffer exports (e.g. memoryview instances).
5544
Georg Brandlf9734072008-12-07 15:30:06 +00005545- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5546 method on file objects with closefd=False. The file descriptor is still
5547 kept open but the file object behaves like a closed file. The ``FileIO``
5548 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00005550- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00005557- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5558 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5559 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5560 of using the replace error handler in PyUnicode_DecodeUTF8().

Guilherme Polo2a998fa2009-06-21 17:40:07 +00006165- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6166 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6167 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6168 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00006170- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006171 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006172 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00006174- Issue #5083: New 'gui' resource for regrtest.
