224
Ned Deily657b2de2011-06-28 19:51:30 -0700225- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
226 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
227 interpreter process. This could cause failures in non-Distutils subprocesses
228 and was unreliable since tests or user programs could modify the interpreter
229 environment after Distutils set it. Instead, have Distutils set the the
230 deployment target only in the environment of each build subprocess. It is
231 still possible to globally override the default by setting
232 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
233 greater or equal to the default value, the value with which the interpreter
234 was built.

R. David Murrayb7deff12011-01-30 06:21:28 +0000907- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
908 files in binary mode, using the email package's binary support to parse
909 arbitrary email messages. StringIO and text file input is deprecated,
910 and string input fails early if non-ASCII characters are used, where
911 previously it would fail when the email was processed in a later step.
912
Nick Coghlan793ee1f2011-01-30 01:24:08 +0000913- Issue #10845: Mitigate the incompatibility between the multiprocessing

Ned Deily806c9442011-01-29 18:43:56 +0000922- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
923 preventing a confusing hung appearance on OS X with the windows
924 obscured.
925
Ned Deily70063932011-01-29 18:29:01 +0000926- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the

936 with a None body.
937
Raymond Hettingera63a3122011-01-26 20:34:14 +0000938- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
939 keyword-only argument. The preceding positional argument was deprecated,
940 so it made no sense to add filter as a positional argument.
941
Raymond Hettinger512d2cc2011-01-25 21:32:39 +0000942- Issue #11004: Repaired edge case in deque.count().

Victor Stinnerf2e439f2011-01-23 00:11:58 +0000954- Issue #10955: zipimport uses ASCII encoding instead of cp437 to decode
Victor Stinner4ee65a92011-01-22 10:30:29 +0000955 filenames, at bootstrap, if the codec registry is not ready yet. It is still
956 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +0000957 for all file entries in the ZIP file.

965 a symbol named FSTAT.
966
Armin Ronacher8d96d772011-01-22 13:13:05 +0000967- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
968 encoding. This is the preferred encoding of PEP 3333 and the base encoding
969 of HTTP 1.1.
970
Armin Ronacher59531282011-01-22 13:44:22 +0000971- To match the behaviour of HTTP server, the HTTP client library now also
972 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
973 that for incoming headers which makes this behaviour now consistent in
974 both incoming and outgoing direction.
975
Steven Bethardb0270112011-01-24 21:02:50 +0000976- Issue #9509: argparse now properly handles IOErrors raised by

Georg Brandl255abdd2011-01-16 14:17:26 +00001010- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
1011 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
1012 translates newlines (\r\n => \n).

1077 is made for all headers in any serialized message at serialization time. This
1078 provides protection against header injection attacks.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001729- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
1730 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001731 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001732 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001733 encoding and to encode command line arguments on this OS.

1738
Benjamin Peterson230b2062010-10-16 03:45:45 +00001739- Issue #9997: Don't let the name "top" have special significance in scope

2126 with a non-empty format string. This is an effort to future-proof user
2127 code. If a derived class does not currently implement __format__ but later
2128 adds its own __format__, it would most likely break user code that had
2129 supplied a format string. This will be changed to a DeprecationWaring in
2130 Python 3.3 and it will be an error in Python 3.4.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002136- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2137 functions from the libc caused the methods .upper() and lower() to become
2138 locale aware and created subtly wrong results.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002143- Issue #4617: Previously it was illegal to delete a name from the local
2144 namespace if it occurs as a free variable in a nested block. This limitation
2145 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2146
Georg Brandl27a28582010-10-10 09:49:21 +00002147- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2148 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2149 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2150 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002185- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002186 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002187 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002188 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002213 retry the select() loop instead of bailing out. This is because select() can

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002295- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002296 it possible for the user to create self-referencing ordered dictionaries which
2297 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002298 approach of using weakref proxies so that reference cycles never get created
2299 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +00002301- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002305- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2306 environment variable to set the filesystem encoding at Python startup.
2307 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2308 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002314- The pprint module now supports printing OrderedDicts in their given order

2319
Georg Brandl27a28582010-10-10 09:49:21 +00002320- Issue #9707: Rewritten reference implementation of threading.local which is
2321 friendlier towards reference cycles. This change is not normally visible
2322 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002323
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002324- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2325 still return the id of the parent process after it has exited. This process
2326 id may even have been reused by another unrelated process.
2327
Georg Brandl27a28582010-10-10 09:49:21 +00002328- Issue #9792: In case of connection failure, socket.create_connection() would
2329 swallow the exception and raise a new one, making it impossible to fetch the
2330 original errno, or to filter timeout errors. Now the original error is
2331 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002333- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2334 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2335 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002337- Updates to the random module:
2338
Georg Brandl27a28582010-10-10 09:49:21 +00002339 * Document which parts of the module are guaranteed to stay the same across
2340 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002341
Georg Brandl27a28582010-10-10 09:49:21 +00002342 * Update the seed() method to use all of the bits in a string instead of just
2343 the hash value. This makes better use of the seed value and assures the
2344 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002345
Georg Brandl27a28582010-10-10 09:49:21 +00002346 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2347 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2348 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002349
2350 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002369- hashlib has two new constant attributes: algorithms_guaranteed and
2370 algorithms_avaiable that respectively list the names of hash algorithms
2371 guaranteed to exist in all Python implementations and the names of hash
2372 algorithms available in the current process.
2373
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002374- A new package ``concurrent.futures`` as defined by PEP 3148.

2501 return characters from the full Unicode range, even on narrow unicode builds
2502 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2503 in Python is that unicodedata.numeric() now returns the correct value for
2504 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00002523 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2524 objects are output as-is.

Antoine Pitrou042b1282010-08-13 21:15:58 +00002529
Georg Brandl649971e2010-09-05 17:06:50 +00002530- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2531 use PyUnicode_FromFormatV() to format the warning message.

2539 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002540
Georg Brandl649971e2010-09-05 17:06:50 +00002541- Issue #9416: Fix some issues with complex formatting where the output with no
2542 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002543
2544 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2545 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Victor Stinner8182b712010-07-28 00:40:58 +00002877- Issue #8991: convertbuffer() rejects discontigious buffers.
2878
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00002879- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
2880 compiler.
2881
Benjamin Petersonccabcd42010-07-07 20:54:01 +00002882- Issue #8413: structsequence now subclasses tuple.
2883
Ezio Melotti57221d02010-07-01 07:32:02 +00002884- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002885 start byte and the continuation byte(s) are now considered invalid, instead of
2886 the number of bytes specified by the start byte. E.g.:
2887 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2888 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2889 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2890 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00002891
Georg Brandl62069d32010-07-31 08:56:11 +00002892- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
2893 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00002894
Benjamin Peterson88968ad2010-06-25 19:30:21 +00002895- Be more specific in error messages about positional arguments.
2896
Victor Stinner4aae1eb2010-06-24 22:08:25 +00002897- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
2898 objects, as described in the documentation.
2899
Victor Stinner0fe25a42010-06-17 23:08:50 +00002900- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.

Georg Brandl62069d32010-07-31 08:56:11 +00002904- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
2905 dealing with unary minus applied to a constant. The removed code was mutating
2906 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00002907
Victor Stinner554f3f02010-06-16 23:33:54 +00002908- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00002909 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00002910 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002911 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002912
Victor Stinner25e8ec42010-06-25 00:02:38 +00002913- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
2914 "w*" format instead. Add tests for "w*" format.
2915
Victor Stinner06e49dd2010-06-13 18:21:50 +00002916- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00002917 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00002918 string formats.
2919
Georg Brandl62069d32010-07-31 08:56:11 +00002920- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002921 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2922 location of the raised exception.
2923
Victor Stinner313a1202010-06-11 23:56:51 +00002924- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2925 filenames and enable os.fsencode().
2926
Benjamin Peterson285a6892010-06-22 19:21:52 +00002927- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2928
Georg Brandl62069d32010-07-31 08:56:11 +00002929- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2930 interpreter with characters outside the Basic Multilingual Plane (higher than
2931 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00002932
Georg Brandl62069d32010-07-31 08:56:11 +00002933- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2934 TypeError instead of giving a DeprecationWarning when a float is parsed using
2935 the 'L' code (for long long). (All other integer codes already raise
2936 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002937
Victor Stinner600d3be2010-06-10 12:00:55 +00002938- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2939 enable shortcuts for upper case encoding name. Add also a shortcut for
2940 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2941
Georg Brandl62069d32010-07-31 08:56:11 +00002942- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2943 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002944
2945- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002946 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002947 like bytearray.
2948
Georg Brandl62069d32010-07-31 08:56:11 +00002949- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002950 used anymore and it was never documented.
2951
Georg Brandl62069d32010-07-31 08:56:11 +00002952- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00002953
Georg Brandl62069d32010-07-31 08:56:11 +00002954- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
2955 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002956
Georg Brandl62069d32010-07-31 08:56:11 +00002957- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2958 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2959 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2960 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002961
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002962- Issue #8748: Fix two issues with comparisons between complex and integer
2963 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002964 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2965 (2) The comparison raised an OverflowError for large integers, leading to
2966 unpredictable exceptions when combining integers and complex objects in sets
2967 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002968
Victor Stinner7d79b8b2010-05-19 20:40:50 +00002969- Issue #8766: Initialize _warnings module before importing the first module.
2970 Fix a crash if an empty directory called "encodings" exists in sys.path.
2971
Victor Stinner9ca9c252010-05-19 16:53:30 +00002972- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002973 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002974 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00002975
Georg Brandl62069d32010-07-31 08:56:11 +00002976- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2977 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002978
Victor Stinnerae6265f2010-05-15 16:27:27 +00002979- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2980 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002981 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002982 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00002983
Victor Stinner59e62db2010-05-15 13:14:32 +00002984- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00002985 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00002986
Victor Stinnerb744ba12010-05-15 12:27:16 +00002987- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00002988 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00002989 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
2990
Victor Stinner0964ee12010-04-30 16:48:45 +00002991- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00002992 PyUnicode_FromString() to support surrogates in the filename and use the right
2993 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00002994
Georg Brandl8569e582010-05-19 20:57:08 +00002995- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
2996
Georg Brandl62069d32010-07-31 08:56:11 +00002997- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00002998
Benjamin Petersonfb886362010-04-24 18:21:17 +00002999- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3000 arguments.
3001
Victor Stinner14284c22010-04-23 12:02:30 +00003002- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003003 indirectly Python signal handlers anymore because mywrite() ignores exceptions
3004 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00003005
Victor Stinner31be90b2010-04-22 19:38:16 +00003006- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing

Victor Stinner31be90b2010-04-22 19:38:16 +00003008
Georg Brandl62069d32010-07-31 08:56:11 +00003009- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
3010 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00003011
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00003012- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00003013 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
3014 compared to the dynamic memory allocation fallback. Patch by Charles-François

3093 crash in many places because of the PyByteArray_AS_STRING() macro returning
3094 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003096- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003097 where the right hand operand is a set of constants, by turning the set into a
3098 frozenset and pre-building it as a constant. The comparison operation is made
3099 against the constant instead of building a new set each time it is executed (a
3100 similar optimization already existed which turned a list of constants into a
3101 pre-built tuple). Patch and additional tests by Dave Malcolm.

3128 least on IEEE 754 platforms), and in particular does not depend on the
3129 internal representation of an int.

3405 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003406 applications that use a lot of regular expressions and limits the impact of
3407 the performance hit anytime the cache is exceeded.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003780 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003781 relies on the system threading library, so as to avoid a semi-busy wait loop.

Georg Brandl62069d32010-07-31 08:56:11 +00003816- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3817 InvalidOperation instead of returning False. (Comparisons involving a quiet
3818 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3819 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00003821- Issue #2531: Comparison operations between floats and Decimal instances now
3822 return a result based on the numeric values of the operands; previously they
3823 returned an arbitrary result based on the relative ordering of id(float) and
3824 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3825 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003826
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003827- Added a subtract() method to collections.Counter().
3828
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003829- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003830 argument `-` which tells it to read files to compile from stdin. Each line is
3831 read on demand and the named file is compiled immediately. (Original patch by
3832 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00003834- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00003838- Comparisons using one of <, <=, >, >= between a complex instance and a
3839 Fractions instance now raise TypeError instead of returning True/False. This
3840 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3841 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003884- The internals of the subprocess module on POSIX systems have been replaced by
3885 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3886 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003887
Georg Brandl62069d32010-07-31 08:56:11 +00003888- subprocess.Popen now has restore_signals and start_new_session features. The
3889 default of restore_signals=True is a new behavior compared to earlier Python
3890 versions. This means that signals such as SIGPIPE are not ignored by default
3891 in subprocesses launched by Python (Issue #1652).

3978 position when calling `truncate()`. It would previously change the file
3979 position to the given argument, which goes against the tradition of

3984 archive. The new implementation is significantly faster and can be wrapped in
3985 a :class:`io.BufferedReader` object for more speedups. It also solves an
3986 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00004322- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004323 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4324 PyPycLoader inherit from this class and provide implementations in relation to
4325 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004326
Brett Cannon64ef00f2009-07-20 03:19:18 +00004327- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4328 the documentation said it did even though the code in PyLoader relied on the
4329 abstract method required by ResourceLoader.
4330
Georg Brandl62069d32010-07-31 08:56:11 +00004331- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004384- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004385 compared to other unix systems. In particular, os.getgroups() does not reflect
4386 any changes made using os.setgroups() but basicly always returns the same
4387 information as the id command. os.getgroups() can now return more than 16
4388 groups on MacOSX.

4414 Prior to this change, timezone adjustment in utctimetuple() could produce
4415 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

4419 directive. When the ``%z`` directive is present in the format string, an
4420 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4421 ``datetime.timezone`` instance constructed from the parsed offset. If both

4427 ``datetime.timezone``, return fixed name and UTC offset from their
4428 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4429 returns ``None``. A class attribute, ``utc`` contains an instance

4986 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
4987 corrects a pydoc regression.
4988
Georg Brandl5f90d792010-08-01 22:31:05 +00004989- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00004990 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005031*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005032
5033Core and Builtins
5034-----------------
5035
Mark Dickinson865e01a2009-05-07 16:37:01 +00005036- Issue #5914: Add new C API function PyOS_string_to_double, and
5037 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5038
Eric Smith741191f2009-05-06 13:08:15 +00005039- Issue #3382: float.__format__, complex.__format__, and %-formatting
5040 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5041 affects nan -> NAN and inf -> INF.
5042
Mark Hammond5a607a32009-05-06 08:04:54 +00005043- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5044 in all operations, including splitdrive, split, etc. splitunc() now issues
5045 a PendingDeprecation warning.
5046
Eric Smith63376222009-05-05 14:04:18 +00005047- Issue #5920: For float.__format__, change the behavior with the
5048 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5049 to be like 'g' but with at least one decimal point and with a
5050 default precision of 12. Previously, the behavior the same but with
5051 a default precision of 6. This more closely matches str(), and
5052 reduces surprises when adding alignment flags to the empty
5053 presentation type. This also affects the new complex.__format__ in
5054 the same way.
5055
Martin v. Löwis011e8422009-05-05 04:43:17 +00005056- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5057
R. David Murrayb18500d2009-05-04 22:59:07 +00005058- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5059 shadowed by classtype's, even if it was None. property now
5060 inserts the __doc__ into the subclass instance __dict__.
5061
Antoine Pitrou244651a2009-05-04 18:56:13 +00005062- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5063 sequences. Patch by Nick Barnes and Victor Stinner.
5064
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005065- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005066
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005067- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5068 received a new method, detach(). detach() disconnects the underlying stream
5069 from the buffer or text IO and returns it.
5070
Mark Dickinson33841c32009-05-01 15:37:04 +00005071- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5072 floats with absolute value over 1e50. Also remove length
5073 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5074 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005075
Eric Smith741191f2009-05-06 13:08:15 +00005076- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005077 format(complex(1, 2./3), '.5') now produces a sensible result.
5078
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005079- Issue #5864: Fix empty format code formatting for floats so that it
5080 never gives more than the requested number of significant digits.
5081
Eric Smith6dc46f52009-04-27 20:39:49 +00005082- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5083 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5084
Eric Smithcc32a112009-04-26 21:35:14 +00005085- Issue #5835: Deprecate PyOS_ascii_formatd.
5086
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005087- Issue #4971: Fix titlecase for characters that are their own
5088 titlecase, but not their own uppercase.
5089
Benjamin Peterson193152c2009-04-25 01:08:45 +00005090- Issue #5283: Setting __class__ in __del__ caused a segfault.
5091
Mark Dickinsonad476da2009-04-23 19:14:16 +00005092- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5093 z involves nans, infs or negative zeros.
5094
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005095- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005096
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005097- Issue #1869 (and many duplicates): make round(x, n) correctly
5098 rounded for a float x, by using the decimal <-> binary conversions
5099 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5100 consistently agrees with format(x, '.2f').
5101
Benjamin Petersonae937c02009-04-18 20:54:08 +00005102- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5103 some builtin types.
5104
Eric Smith0923d1d2009-04-16 20:16:10 +00005105- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5106
Eric Smith35e84722009-04-16 20:21:28 +00005107- Issue #5515: str.format() type 'n' combined with commas and leading
5108 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005109
5110- Implement PEP 378, Format Specifier for Thousands Separator, for
5111 floats.
5112
Mark Dickinson3370cce2009-04-17 22:40:53 +00005113- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005114 1e11, not 1e12. This avoids printing 13 significant digits in
5115 situations where only 12 of them are correct. Example problem
5116 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5117 long time.)
5118
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005119- Issue #1580: On most platforms, use a 'short' float repr: for a
5120 finite float x, repr(x) now outputs a string based on the shortest
5121 sequence of decimal digits that rounds to x. Previous behaviour was
5122 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005123 Another minor difference is that the new repr switches to
5124 exponential notation at 1e16 instead of the previous 1e17; this
5125 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005126
5127 There's a new sys attribute sys.float_repr_style, which takes
5128 the value 'short' to indicate that we're using short float repr,
5129 and 'legacy' if the short float repr isn't available for one
5130 reason or another.
5131
5132 The float repr change involves incorporating David Gay's 'perfect
5133 rounding' code into the Python core (it's in Python/dtoa.c). As a
5134 secondary consequence, all string-to-float and float-to-string
5135 conversions (including all float formatting operations) will be
5136 correctly rounded on these platforms.
5137
Georg Brandl5f90d792010-08-01 22:31:05 +00005138 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005139 this change does not apply.
5140
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005141- Issue #5759: float() didn't call __float__ on str subclasses.
5142
Georg Brandlabc38772009-04-12 15:51:51 +00005143- The string.maketrans() function is deprecated; there is a new static method
5144 maketrans() on the bytes and bytearray classes. This removes confusion about
5145 the types string.maketrans() is supposed to work with, and mirrors the
5146 methods available on the str class.
5147
R. David Murraydc6da8a2009-04-09 22:16:43 +00005148- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5149 its clarity and its speed.
5150
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005151- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005152 to avoid compiler warnings.
5153
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005154- Issue #3739: The unicode-internal encoder now reports the number of characters
5155 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00005292- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
5293
Benjamin Peterson7fe98532009-04-02 00:33:55 +00005294- Issue #5499: The 'c' code for argument parsing functions now only accepts a
5295 byte, and the 'C' code only accepts a unicode character.
5296
Georg Brandl406b3d82009-04-11 21:24:37 +00005297- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
5298 when hitting the recursion limit under certain circumstances.
5299
Brett Cannon0759dd62009-04-01 18:13:07 +00005300- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
5301
Georg Brandlab6f2f62009-03-31 04:16:10 +00005302- Fix a segfault when running test_exceptions with coverage, caused by
5303 insufficient checks in accessors of Exception.__context__.
5304
Guido van Rossum0ad59d42009-03-30 22:01:35 +00005305- Issue #5604: non-ASCII characters in module name passed to
5306 imp.find_module() were converted to UTF-8 while the path is
5307 converted to the default filesystem encoding, causing nonsense.
5308
Benjamin Peterson09832742009-03-26 17:15:46 +00005309- Issue #5126: str.isprintable() returned False for space characters.
5310
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005311- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5312 the end sys.path, for compatibility with the system install of Python.
5313
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005314- Issue #4688: Add a heuristic so that tuples and dicts containing only
5315 untrackable objects are not tracked by the garbage collector. This can
5316 reduce the size of collections and therefore the garbage collection overhead
5317 on long-running programs, depending on their particular use of datatypes.
5318
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005319- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

5322
Mark Dickinsonbd792642009-03-18 20:06:12 +00005323- Issue #4258: Make it possible to use base 2**30 instead of base
5324 2**15 for the internal representation of integers, for performance
5325 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5326 --enable-big-digits option to configure, which overrides the
5327 default. Add sys.int_info structseq to provide information about
5328 the internal format.
5329
Mark Dickinson081dfee2009-03-18 14:47:41 +00005330- Issue #4474: PyUnicode_FromWideChar now converts characters outside
5331 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5332 and sizeof(Py_UNICODE) == 2.
5333
Eric Smith8ec90442009-03-14 12:29:34 +00005334- Issue #5237: Allow auto-numbered fields in str.format(). For
5335 example: '{} {}'.format(1, 2) == '1 2'.
5336
Antoine Pitrou652e7072009-03-13 19:25:20 +00005337- Issue #5392: when a very low recursion limit was set, the interpreter would
5338 abort with a fatal error after the recursion limit was hit twice.
5339
Matthias Klose042f1332009-04-04 14:32:42 +00005340- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
5341 short file names.

R. David Murray548ac412009-04-02 19:44:43 +00005347 mailbox.MH.get_message().
5348
Hye-Shik Chang944820b2009-04-02 10:33:16 +00005349- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
5350 error substitutions from non-strict codec error callbacks in
5351 incrementalencoder and StreamWriter.
5352
Georg Brandl33c28812009-04-01 23:07:29 +00005353- Issue #5656: Fix the coverage reporting when running the test suite with

5371
Brett Cannon7f6b4f82009-03-30 21:30:26 +00005372- Issue #5236: Change time.strptime() to only take strings. Didn't work with
5373 bytes already but the failure was non-obvious.
5374
Jesse Noller7af4ef82009-03-30 16:47:15 +00005375- Issue #5177: Multiprocessing's SocketListener class now uses

5383
Benjamin Peterson59406a92009-03-26 17:10:29 +00005384- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
5385 io.BufferedRandom have been deprecated for removal in Python 3.2.
5386
Lars Gustäbel42e00912009-03-22 20:34:29 +00005387- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5388 forever on incomplete input. That caused tarfile.open() to hang when used
5389 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5390 partial bzip2 compressed data.
5391
Mark Dickinson79f52032009-03-17 23:12:51 +00005392- Issue #2110: Add support for thousands separator and 'n' type

5397
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00005398- The error detection code in FileIO.close() could fail to reflect the `errno`
5399 value, and report it as -1 instead.

5408
Mark Dickinsonae681df2009-03-21 10:26:31 +00005409- Issue #5463: In struct module, remove deprecated overflow wrapping
5410 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00005411 struct.error instead of returning b'\xff\xff\xff\xff'. The
5412 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5413 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005440- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5441 it now forces its argument to double before testing for infinity.
5442
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005443- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5444 returns a non-number type.
5445
Benjamin Peterson87618552009-02-08 15:00:52 +00005446- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005452
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005453- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005454 were suppressing all exceptions. These include list() and bytearray().
5455
Mark Dickinson1124e712009-01-28 21:25:58 +00005456- Issue #4707: round(x, n) now returns an integer if x is an integer.
5457 Previously it returned a float.

5460 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5461 evaluation loop is compiled with a new dispatch mechanism which gives
5462 speedups of up to 20%, depending on the system, on various benchmarks.

Georg Brandl65ce6ad2010-09-05 17:32:31 +00005475 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005476
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005477- Issue #4935: The overflow checking code in the expandtabs() method common
5478 to str, bytes and bytearray could be optimized away by the compiler, letting
5479 the interpreter segfault instead of raising an error.
5480
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005481- Issue #3720: Fix a crash when an iterator modifies its class and removes its

5495
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005496- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5497 collecting the oldest generation) so that allocating lots of objects without
5498 destroying them does not show quadratic performance. Based on a proposal by
5499 Martin von Löwis at
5500 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5501
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005502- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005503 having been closed (for instance, a read() call could return some
5504 previously buffered data). Patch by Dmitry Vasiliev.
5505
Antoine Pitrou05608432009-01-09 18:53:14 +00005506- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5507 flag to work properly. Furthermore, when specifying -u, the text stdout
5508 and stderr streams have line-by-line buffering enabled (the default being
5509 to buffer arbitrary chunks of data).
5510
Raymond Hettinger35631532009-01-09 03:58:09 +00005511- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5512 instead of ints (reducing its size from 4 to 8 times thereby reducing
5513 Python's overall memory).
5514
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005515- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5516 an existing .py counterpart, override the co_filename attributes of all
5517 code objects if the original filename is obsolete (which can happen if the
5518 file has been renamed, moved, or if it is accessed through different paths).
5519 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5520
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005521- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5522 one byte. Also fixes the meaning of len() so that it returns the number of
5523 items, rather than the size in bytes.
5524
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005525- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5526
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005527- Issue #4747: When the terminal does not use utf-8, executing a script with

5534 did not get collected.
5535
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005536- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5537 where the tp_hash and tp_dict slots are both NULL.
5538
Georg Brandlccc47b62008-12-28 11:44:14 +00005539- Issue #4759: None is now allowed as the first argument of
5540 bytearray.translate(). It was always allowed for bytes.translate().
5541
Skip Montanaro80072cb2008-12-23 03:51:14 +00005542- Added test case to ensure attempts to read from a file opened for writing
5543 fail.

5549
Antoine Pitrou621601a2008-12-17 23:18:19 +00005550- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5551 print elapsed times, not only when some objects are uncollectable /
5552 unreachable. Original patch by Neil Schemenauer.
5553
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005554- Issue #3439: Add a bit_length method to int.
5555
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005556- Issue #2173: When getting device encoding, check that return value of
5557 nl_langinfo is not the empty string. This was causing silent build
5558 failures on OS X.
5559
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005560- Issue #4597: Fixed several opcodes that weren't always propagating
5561 exceptions.
5562
5563- Issue #4589: Fixed exception handling when the __exit__ function of a

Antoine Pitrou08838b62009-01-21 00:55:13 +00005913- Issue #5008: When a file is opened in append mode with the new IO library,
5914 do an explicit seek to the end of file (so that e.g. tell() returns the

5946 appropriately when it is being used via socket.makefile() objects
5947 rather than delaying the close by waiting for garbage collection to do it.
5948
Raymond Hettingerb8baf632009-01-14 02:20:07 +00005949- Issue #1696199: Add collections.Counter() for rapid and convenient

6199 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6200 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6201 skip the tests if DISPLAY is defined but can't be used.

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006204 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006205 from test support, which does the conversion.
