55 Linux 3.0.
56
R David Murray46346762011-07-18 21:38:54 -040057- Issue #7484: smtplib no longer puts <> around addresses in VRFY and EXPN
58 commands; they aren't required and in fact postfix doesn't support that form.
59
Antoine Pitrou0b447952011-07-16 23:52:02 +020060- Close the call queue in concurrent.futures.ProcessPoolExecutor when

211
Ned Deily657b2de2011-06-28 19:51:30 -0700212- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
213 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
214 interpreter process. This could cause failures in non-Distutils subprocesses
215 and was unreliable since tests or user programs could modify the interpreter
216 environment after Distutils set it. Instead, have Distutils set the the
217 deployment target only in the environment of each build subprocess. It is
218 still possible to globally override the default by setting
219 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
220 greater or equal to the default value, the value with which the interpreter
221 was built.

R. David Murrayb7deff12011-01-30 06:21:28 +0000893- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
894 files in binary mode, using the email package's binary support to parse
895 arbitrary email messages. StringIO and text file input is deprecated,
896 and string input fails early if non-ASCII characters are used, where
897 previously it would fail when the email was processed in a later step.
898
Nick Coghlan793ee1f2011-01-30 01:24:08 +0000899- Issue #10845: Mitigate the incompatibility between the multiprocessing
900 module on Windows and the use of package, zipfile or directory execution
901 by special casing main modules that actually *are* called __main__.py.
902
Éric Araujoac4e58e2011-01-29 20:32:11 +0000903- Issue #11045: Protect logging call against None argument.

Ned Deily806c9442011-01-29 18:43:56 +0000908- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
909 preventing a confusing hung appearance on OS X with the windows
910 obscured.
911
Ned Deily70063932011-01-29 18:29:01 +0000912- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the

922 with a None body.
923
Raymond Hettingera63a3122011-01-26 20:34:14 +0000924- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
925 keyword-only argument. The preceding positional argument was deprecated,
926 so it made no sense to add filter as a positional argument.
927
Raymond Hettinger512d2cc2011-01-25 21:32:39 +0000928- Issue #11004: Repaired edge case in deque.count().

Victor Stinner4ee65a92011-01-22 10:30:29 +0000941 filenames, at bootstrap, if the codec registry is not ready yet. It is still
942 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +0000943 for all file entries in the ZIP file.

951 a symbol named FSTAT.
952
Armin Ronacher8d96d772011-01-22 13:13:05 +0000953- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
954 encoding. This is the preferred encoding of PEP 3333 and the base encoding
955 of HTTP 1.1.
956
Armin Ronacher59531282011-01-22 13:44:22 +0000957- To match the behaviour of HTTP server, the HTTP client library now also
958 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
959 that for incoming headers which makes this behaviour now consistent in
960 both incoming and outgoing direction.
961
Steven Bethardb0270112011-01-24 21:02:50 +0000962- Issue #9509: argparse now properly handles IOErrors raised by

997 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
998 translates newlines (\r\n => \n).

Georg Brandl255abdd2011-01-16 14:17:26 +00001061 continuation line in the formatted value has no leading white space and looks

1063 is made for all headers in any serialized message at serialization time. This
1064 provides protection against header injection attacks.

1716 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001717 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001718 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001719 encoding and to encode command line arguments on this OS.

2112 with a non-empty format string. This is an effort to future-proof user
2113 code. If a derived class does not currently implement __format__ but later
2114 adds its own __format__, it would most likely break user code that had
2115 supplied a format string. This will be changed to a DeprecationWaring in
2116 Python 3.3 and it will be an error in Python 3.4.

2120 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

2123 functions from the libc caused the methods .upper() and lower() to become
2124 locale aware and created subtly wrong results.
2125
Georg Brandl27a28582010-10-10 09:49:21 +00002126- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002129- Issue #4617: Previously it was illegal to delete a name from the local
2130 namespace if it occurs as a free variable in a nested block. This limitation
2131 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2132
Georg Brandl27a28582010-10-10 09:49:21 +00002133- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2134 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2135 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2136 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002137

Éric Araujoef777bd2010-10-05 00:04:20 +00002171- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002172 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002173 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002174 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002199 retry the select() loop instead of bailing out. This is because select() can

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002281- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002282 it possible for the user to create self-referencing ordered dictionaries which
2283 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002284 approach of using weakref proxies so that reference cycles never get created
2285 in the first place.
2286
Victor Stinnercb043522010-09-10 23:49:04 +00002287- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002291- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2292 environment variable to set the filesystem encoding at Python startup.
2293 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2294 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002300- The pprint module now supports printing OrderedDicts in their given order

2305
Georg Brandl27a28582010-10-10 09:49:21 +00002306- Issue #9707: Rewritten reference implementation of threading.local which is
2307 friendlier towards reference cycles. This change is not normally visible
2308 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002310- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2311 still return the id of the parent process after it has exited. This process
2312 id may even have been reused by another unrelated process.
2313
Georg Brandl27a28582010-10-10 09:49:21 +00002314- Issue #9792: In case of connection failure, socket.create_connection() would
2315 swallow the exception and raise a new one, making it impossible to fetch the
2316 original errno, or to filter timeout errors. Now the original error is
2317 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002323- Updates to the random module:
2324
Georg Brandl27a28582010-10-10 09:49:21 +00002325 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002328 * Update the seed() method to use all of the bits in a string instead of just
2329 the hash value. This makes better use of the seed value and assures the
2330 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002331
Georg Brandl27a28582010-10-10 09:49:21 +00002332 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2333 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2334 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002335
2336 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002355- hashlib has two new constant attributes: algorithms_guaranteed and

2357 guaranteed to exist in all Python implementations and the names of hash
2358 algorithms available in the current process.

2487 return characters from the full Unicode range, even on narrow unicode builds
2488 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2489 in Python is that unicodedata.numeric() now returns the correct value for
2490 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00002509 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2510 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00002516- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2517 use PyUnicode_FromFormatV() to format the warning message.

2525 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002526
Georg Brandl649971e2010-09-05 17:06:50 +00002527- Issue #9416: Fix some issues with complex formatting where the output with no
2528 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002529
2530 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2531 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

2869
Ezio Melotti57221d02010-07-01 07:32:02 +00002870- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002871 start byte and the continuation byte(s) are now considered invalid, instead of
2872 the number of bytes specified by the start byte. E.g.:
2873 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2874 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2875 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2876 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00002877
Georg Brandl62069d32010-07-31 08:56:11 +00002878- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
2879 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00002880
Benjamin Peterson88968ad2010-06-25 19:30:21 +00002881- Be more specific in error messages about positional arguments.

Georg Brandl62069d32010-07-31 08:56:11 +00002890- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
2891 dealing with unary minus applied to a constant. The removed code was mutating
2892 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00002893
Victor Stinner554f3f02010-06-16 23:33:54 +00002894- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00002895 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00002896 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002897 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002898
Victor Stinner25e8ec42010-06-25 00:02:38 +00002899- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use

2901
Victor Stinner06e49dd2010-06-13 18:21:50 +00002902- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00002903 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00002904 string formats.
2905
Georg Brandl62069d32010-07-31 08:56:11 +00002906- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002907 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2908 location of the raised exception.
2909
Victor Stinner313a1202010-06-11 23:56:51 +00002910- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2911 filenames and enable os.fsencode().
2912
Benjamin Peterson285a6892010-06-22 19:21:52 +00002913- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2914
Georg Brandl62069d32010-07-31 08:56:11 +00002915- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2916 interpreter with characters outside the Basic Multilingual Plane (higher than
2917 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00002918
Georg Brandl62069d32010-07-31 08:56:11 +00002919- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2920 TypeError instead of giving a DeprecationWarning when a float is parsed using
2921 the 'L' code (for long long). (All other integer codes already raise
2922 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002923
Victor Stinner600d3be2010-06-10 12:00:55 +00002924- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2925 enable shortcuts for upper case encoding name. Add also a shortcut for
2926 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2927
Georg Brandl62069d32010-07-31 08:56:11 +00002928- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2929 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002930
2931- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002932 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002933 like bytearray.
2934
Georg Brandl62069d32010-07-31 08:56:11 +00002935- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002936 used anymore and it was never documented.
2937
Georg Brandl62069d32010-07-31 08:56:11 +00002938- In str.format(), raise a ValueError when indexes to arguments are too large.

2941 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002942
Georg Brandl62069d32010-07-31 08:56:11 +00002943- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2944 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2945 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2946 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002947
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002948- Issue #8748: Fix two issues with comparisons between complex and integer
2949 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002950 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2951 (2) The comparison raised an OverflowError for large integers, leading to
2952 unpredictable exceptions when combining integers and complex objects in sets
2953 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002954

2957
Victor Stinner9ca9c252010-05-19 16:53:30 +00002958- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002959 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002960 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00002961
Georg Brandl62069d32010-07-31 08:56:11 +00002962- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2963 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002964
Victor Stinnerae6265f2010-05-15 16:27:27 +00002965- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2966 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002967 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002968 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00002969
Victor Stinner59e62db2010-05-15 13:14:32 +00002970- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00002971 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00002972
Victor Stinnerb744ba12010-05-15 12:27:16 +00002973- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00002974 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00002975 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
2976
Victor Stinner0964ee12010-04-30 16:48:45 +00002977- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00002978 PyUnicode_FromString() to support surrogates in the filename and use the right
2979 encoding.

3080 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003082- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003083 where the right hand operand is a set of constants, by turning the set into a
3084 frozenset and pre-building it as a constant. The comparison operation is made
3085 against the constant instead of building a new set each time it is executed (a
3086 similar optimization already existed which turned a list of constants into a
3087 pre-built tuple). Patch and additional tests by Dave Malcolm.

3094 including: (1) a serious 'wrong output' bug that could occur for long (> 40
3095 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
3096 parsing certain long numeric strings corresponding to subnormal values, (3) a
3097 memory leak for some values large enough to cause overflow, and (4) a number
3098 of flaws that could lead to incorrectly rounded results.

3114 least on IEEE 754 platforms), and in particular does not depend on the
3115 internal representation of an int.

3393 the performance hit anytime the cache is exceeded.

R. David Murrayb2416e52010-04-12 16:58:02 +00003773- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00003774 filename and date, conforming to the 'standards' they were originally designed
3775 to follow. This improves compatibility with patch tools.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00003791- Add functools.total_ordering() and functools.cmp_to_key().
3792
Georg Brandl62069d32010-07-31 08:56:11 +00003793- Issue #8257: The Decimal construct now accepts a float instance directly,
3794 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00003795
3796 >>> Decimal(1.1)
3797 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00003802- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3803 InvalidOperation instead of returning False. (Comparisons involving a quiet
3804 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3805 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003806
Georg Brandl62069d32010-07-31 08:56:11 +00003807- Issue #2531: Comparison operations between floats and Decimal instances now
3808 return a result based on the numeric values of the operands; previously they
3809 returned an arbitrary result based on the relative ordering of id(float) and
3810 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3811 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003812
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003813- Added a subtract() method to collections.Counter().
3814
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003815- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003816 argument `-` which tells it to read files to compile from stdin. Each line is
3817 read on demand and the named file is compiled immediately. (Original patch by
3818 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00003820- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3821 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00003822 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00003824- Comparisons using one of <, <=, >, >= between a complex instance and a
3825 Fractions instance now raise TypeError instead of returning True/False. This
3826 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3827 <=> complex, and complex <=> complex comparisons.

3835
Antoine Pitrou910bd512010-03-22 20:11:09 +00003836- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00003837 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3838 silenced.

3844 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
3845 reads and writes are always retried by OpenSSL itself.

Georg Brandl62069d32010-07-31 08:56:11 +00003870- The internals of the subprocess module on POSIX systems have been replaced by
3871 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3872 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003873
Georg Brandl62069d32010-07-31 08:56:11 +00003874- subprocess.Popen now has restore_signals and start_new_session features. The
3875 default of restore_signals=True is a new behavior compared to earlier Python
3876 versions. This means that signals such as SIGPIPE are not ignored by default
3877 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00003878

3964 position when calling `truncate()`. It would previously change the file
3965 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00003966 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3970 archive. The new implementation is significantly faster and can be wrapped in
3971 a :class:`io.BufferedReader` object for more speedups. It also solves an
3972 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004370- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004371 compared to other unix systems. In particular, os.getgroups() does not reflect
4372 any changes made using os.setgroups() but basicly always returns the same
4373 information as the id command. os.getgroups() can now return more than 16
4374 groups on MacOSX.

Brett Cannoncfed0292009-11-05 01:26:57 +00004720- Issue #7248 (part 2): Use a unique temporary directory for importlib source
4721 tests instead of tempfile.tempdir. This prevents the tests from sharing state
4722 between concurrent executions on the same system.

4730 threads could return successfully while some Thread objects were still
4731 referenced. This also introduces a new private function:

4739
R. David Murray0bc11ae2009-10-18 22:18:17 +00004740- Issue #7058: Added save/restore for things like sys.argv and cwd to

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005018
5019Core and Builtins
5020-----------------
5021
Mark Dickinson865e01a2009-05-07 16:37:01 +00005022- Issue #5914: Add new C API function PyOS_string_to_double, and
5023 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5024
Eric Smith741191f2009-05-06 13:08:15 +00005025- Issue #3382: float.__format__, complex.__format__, and %-formatting
5026 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5027 affects nan -> NAN and inf -> INF.
5028
Mark Hammond5a607a32009-05-06 08:04:54 +00005029- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5030 in all operations, including splitdrive, split, etc. splitunc() now issues
5031 a PendingDeprecation warning.
5032
Eric Smith63376222009-05-05 14:04:18 +00005033- Issue #5920: For float.__format__, change the behavior with the
5034 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5035 to be like 'g' but with at least one decimal point and with a
5036 default precision of 12. Previously, the behavior the same but with
5037 a default precision of 6. This more closely matches str(), and
5038 reduces surprises when adding alignment flags to the empty
5039 presentation type. This also affects the new complex.__format__ in
5040 the same way.
5041
Martin v. Löwis011e8422009-05-05 04:43:17 +00005042- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5043
R. David Murrayb18500d2009-05-04 22:59:07 +00005044- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5045 shadowed by classtype's, even if it was None. property now
5046 inserts the __doc__ into the subclass instance __dict__.
5047
Antoine Pitrou244651a2009-05-04 18:56:13 +00005048- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5049 sequences. Patch by Nick Barnes and Victor Stinner.
5050
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005051- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005052
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005053- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5054 received a new method, detach(). detach() disconnects the underlying stream
5055 from the buffer or text IO and returns it.
5056
Mark Dickinson33841c32009-05-01 15:37:04 +00005057- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5058 floats with absolute value over 1e50. Also remove length
5059 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5060 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005061
Eric Smith741191f2009-05-06 13:08:15 +00005062- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005063 format(complex(1, 2./3), '.5') now produces a sensible result.
5064
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005065- Issue #5864: Fix empty format code formatting for floats so that it
5066 never gives more than the requested number of significant digits.
5067
Eric Smith6dc46f52009-04-27 20:39:49 +00005068- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5069 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5070
Eric Smithcc32a112009-04-26 21:35:14 +00005071- Issue #5835: Deprecate PyOS_ascii_formatd.
5072
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005073- Issue #4971: Fix titlecase for characters that are their own
5074 titlecase, but not their own uppercase.
5075
Benjamin Peterson193152c2009-04-25 01:08:45 +00005076- Issue #5283: Setting __class__ in __del__ caused a segfault.
5077
Mark Dickinsonad476da2009-04-23 19:14:16 +00005078- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5079 z involves nans, infs or negative zeros.
5080
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005081- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005082
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005083- Issue #1869 (and many duplicates): make round(x, n) correctly
5084 rounded for a float x, by using the decimal <-> binary conversions
5085 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5086 consistently agrees with format(x, '.2f').
5087
Benjamin Petersonae937c02009-04-18 20:54:08 +00005088- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5089 some builtin types.
5090
Eric Smith0923d1d2009-04-16 20:16:10 +00005091- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5092
Eric Smith35e84722009-04-16 20:21:28 +00005093- Issue #5515: str.format() type 'n' combined with commas and leading
5094 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005095
5096- Implement PEP 378, Format Specifier for Thousands Separator, for
5097 floats.
5098
Mark Dickinson3370cce2009-04-17 22:40:53 +00005099- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005100 1e11, not 1e12. This avoids printing 13 significant digits in
5101 situations where only 12 of them are correct. Example problem
5102 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5103 long time.)
5104
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005105- Issue #1580: On most platforms, use a 'short' float repr: for a
5106 finite float x, repr(x) now outputs a string based on the shortest
5107 sequence of decimal digits that rounds to x. Previous behaviour was
5108 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005109 Another minor difference is that the new repr switches to
5110 exponential notation at 1e16 instead of the previous 1e17; this
5111 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005112
5113 There's a new sys attribute sys.float_repr_style, which takes
5114 the value 'short' to indicate that we're using short float repr,
5115 and 'legacy' if the short float repr isn't available for one
5116 reason or another.
5117
5118 The float repr change involves incorporating David Gay's 'perfect
5119 rounding' code into the Python core (it's in Python/dtoa.c). As a
5120 secondary consequence, all string-to-float and float-to-string
5121 conversions (including all float formatting operations) will be
5122 correctly rounded on these platforms.
5123
Georg Brandl5f90d792010-08-01 22:31:05 +00005124 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005125 this change does not apply.
5126
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005127- Issue #5759: float() didn't call __float__ on str subclasses.
5128
Georg Brandlabc38772009-04-12 15:51:51 +00005129- The string.maketrans() function is deprecated; there is a new static method
5130 maketrans() on the bytes and bytearray classes. This removes confusion about
5131 the types string.maketrans() is supposed to work with, and mirrors the
5132 methods available on the str class.
5133
R. David Murraydc6da8a2009-04-09 22:16:43 +00005134- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5135 its clarity and its speed.
5136
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005137- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005138 to avoid compiler warnings.
5139
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005140- Issue #3739: The unicode-internal encoder now reports the number of characters
5141 consumed like any other encoder (instead of the number of bytes).

Guido van Rossum0ad59d42009-03-30 22:01:35 +00005291- Issue #5604: non-ASCII characters in module name passed to
5292 imp.find_module() were converted to UTF-8 while the path is
5293 converted to the default filesystem encoding, causing nonsense.
5294
Benjamin Peterson09832742009-03-26 17:15:46 +00005295- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005297- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5298 the end sys.path, for compatibility with the system install of Python.
5299
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005300- Issue #4688: Add a heuristic so that tuples and dicts containing only
5301 untrackable objects are not tracked by the garbage collector. This can
5302 reduce the size of collections and therefore the garbage collection overhead
5303 on long-running programs, depending on their particular use of datatypes.
5304
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005305- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
5306 improve its performance. Long divisions and remainder operations
5307 are now between 50% and 150% faster.
5308
Mark Dickinsonbd792642009-03-18 20:06:12 +00005309- Issue #4258: Make it possible to use base 2**30 instead of base
5310 2**15 for the internal representation of integers, for performance
5311 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5312 --enable-big-digits option to configure, which overrides the
5313 default. Add sys.int_info structseq to provide information about
5314 the internal format.
5315
Mark Dickinson081dfee2009-03-18 14:47:41 +00005316- Issue #4474: PyUnicode_FromWideChar now converts characters outside
5317 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5318 and sizeof(Py_UNICODE) == 2.
5319
Eric Smith8ec90442009-03-14 12:29:34 +00005320- Issue #5237: Allow auto-numbered fields in str.format(). For
5321 example: '{} {}'.format(1, 2) == '1 2'.
5322
Antoine Pitrou652e7072009-03-13 19:25:20 +00005323- Issue #5392: when a very low recursion limit was set, the interpreter would
5324 abort with a fatal error after the recursion limit was hit twice.
5325
Matthias Klose042f1332009-04-04 14:32:42 +00005326- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
5327 short file names.

5372
Lars Gustäbel42e00912009-03-22 20:34:29 +00005373- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5374 forever on incomplete input. That caused tarfile.open() to hang when used
5375 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

5415 used when using str.format() with str, int, and float arguments.
5416
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005417- Issue #5249: time.strftime returned malformed string when format string
5418 contained non ascii character on windows.
5419
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005420- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5421 source has already been decoded into str.
5422
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005423- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5424 rotating the object pointer by 4 bits to the right.
5425
Mark Dickinson87ec0852009-02-09 17:15:59 +00005426- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5427 it now forces its argument to double before testing for infinity.
5428
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005429- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5430 returns a non-number type.
5431
Benjamin Peterson87618552009-02-08 15:00:52 +00005432- Issue #5182: Removed memoryview.__str__.
5433
Mark Dickinsonc008a172009-02-01 13:59:22 +00005434- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5435 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005436 the type definition cmpfunc. The tp_compare slot has been renamed
5437 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005438
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005439- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005440 were suppressing all exceptions. These include list() and bytearray().
5441
Mark Dickinson1124e712009-01-28 21:25:58 +00005442- Issue #4707: round(x, n) now returns an integer if x is an integer.
5443 Previously it returned a float.
5444
Antoine Pitroub52ec782009-01-25 16:34:23 +00005445- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5446 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5447 evaluation loop is compiled with a new dispatch mechanism which gives
5448 speedups of up to 20%, depending on the system, on various benchmarks.
5449
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005450- Issue #4874: Most builtin decoders now reject unicode input.

5456
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005457- Issue #4838: When a module is deallocated, free the memory backing the
5458 optional module state data.
5459
Mark Dickinson8055afd2009-01-17 10:04:45 +00005460- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005461 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005462
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005463- Issue #4935: The overflow checking code in the expandtabs() method common
5464 to str, bytes and bytearray could be optimized away by the compiler, letting
5465 the interpreter segfault instead of raising an error.
5466
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005467- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5468 __next__ method.
5469
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005470- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5471 function no longer attempt to call the __long__ slot to convert an object
5472 to an integer. Only the __int__ and __trunc__ slots are examined.
5473
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005474- Issue #4893: Use NT threading on CE.

5477
Antoine Pitrouab868312009-01-10 15:40:25 +00005478- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5479 common cases are optimized thanks to a dedicated fast path and a moderate
5480 amount of loop unrolling.
5481
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005482- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5483 collecting the oldest generation) so that allocating lots of objects without
5484 destroying them does not show quadratic performance. Based on a proposal by
5485 Martin von Löwis at
5486 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5487
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005488- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005489 having been closed (for instance, a read() call could return some
5490 previously buffered data). Patch by Dmitry Vasiliev.
5491
Antoine Pitrou05608432009-01-09 18:53:14 +00005492- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5493 flag to work properly. Furthermore, when specifying -u, the text stdout
5494 and stderr streams have line-by-line buffering enabled (the default being
5495 to buffer arbitrary chunks of data).
5496
Raymond Hettinger35631532009-01-09 03:58:09 +00005497- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5498 instead of ints (reducing its size from 4 to 8 times thereby reducing
5499 Python's overall memory).
5500
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005501- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5502 an existing .py counterpart, override the co_filename attributes of all
5503 code objects if the original filename is obsolete (which can happen if the
5504 file has been renamed, moved, or if it is accessed through different paths).
5505 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5506
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005507- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5508 one byte. Also fixes the meaning of len() so that it returns the number of
5509 items, rather than the size in bytes.
5510
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005511- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5512
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005513- Issue #4747: When the terminal does not use utf-8, executing a script with
5514 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5515
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005516- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5517 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005518
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005519- Issue #3680: Reference cycles created through a dict, set or deque iterator
5520 did not get collected.
5521
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005522- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5523 where the tp_hash and tp_dict slots are both NULL.
5524
Georg Brandlccc47b62008-12-28 11:44:14 +00005525- Issue #4759: None is now allowed as the first argument of
5526 bytearray.translate(). It was always allowed for bytes.translate().
5527
Skip Montanaro80072cb2008-12-23 03:51:14 +00005528- Added test case to ensure attempts to read from a file opened for writing
5529 fail.
5530
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005531- Issue #3106: Speedup some comparisons (str/str and int/int).

5534 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5535
Antoine Pitrou621601a2008-12-17 23:18:19 +00005536- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5537 print elapsed times, not only when some objects are uncollectable /
5538 unreachable. Original patch by Neil Schemenauer.
5539
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005540- Issue #3439: Add a bit_length method to int.
5541
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005542- Issue #2173: When getting device encoding, check that return value of
5543 nl_langinfo is not the empty string. This was causing silent build
5544 failures on OS X.
5545
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005546- Issue #4597: Fixed several opcodes that weren't always propagating
5547 exceptions.
5548
5549- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005550 context manager returns a value that cannot be converted to a bool.
5551
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005552- Issue #4445: Replace "sizeof(PyBytesObject)" with
5553 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5554 bytes instances. On a typical machine this saves 3 bytes of memory
5555 (on average) per allocation of a bytes instance.
5556
Christian Heimesa872de52008-12-05 08:26:55 +00005557- Issue #4533: File read operation was dreadfully slow due to a slowly
5558 growing read buffer. Fixed by using the same growth rate algorithm as
5559 Python 2.x.
5560
Antoine Pitrou5504e892008-12-06 21:27:53 +00005561- Issue #4509: Various issues surrounding resize of bytearray objects to
5562 which there are buffer exports (e.g. memoryview instances).
5563
Georg Brandlf9734072008-12-07 15:30:06 +00005564- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5565 method on file objects with closefd=False. The file descriptor is still
5566 kept open but the file object behaves like a closed file. The ``FileIO``
5567 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005568
Antoine Pitroubc420402008-12-07 20:14:49 +00005569- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5570 larger than 1.

5900 do an explicit seek to the end of file (so that e.g. tell() returns the

6147 supporting objects as input no matter how it was compiled (built in
6148 implementations or external openssl library).
6149
Mark Dickinson29500f62009-01-15 15:36:10 +00006150- Issue #4397: Fix occasional test_socket failure on OS X.

6153
Antoine Pitroubcd5cbe2009-01-08 21:17:16 +00006154- Issue #4751: hashlib now releases the GIL when hashing large buffers
6155 (with a hardwired threshold of 2048 bytes), allowing better parallelization
6156 on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.
6157
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006158- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
6159
Antoine Pitrou31f30b12009-01-02 17:34:35 +00006160- Issue #4738: Each zlib object now has a separate lock, allowing to compress
6161 or decompress several streams at once on multi-CPU systems. Also, the GIL
6162 is now released when computing the CRC of a large buffer. Patch by ebfe.
6163
Georg Brandlb1441c72009-01-03 22:33:39 +00006164- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.

6169 OpenBSD.
Amaury Forgeot d'Arcefae8c42008-11-21 23:08:09 +00006170
Antoine Pitrou3ad3a0d2008-12-18 17:08:32 +00006171- Issue #4583: array.array would not always prohibit resizing when a buffer
6172 has been exported, resulting in an interpreter crash when accessing the
6173 buffer.
6174
Martin v. Löwis841edad2008-11-30 10:36:49 +00006175
Jack Diederiche0cbd692009-04-01 04:27:09 +00006176- Issue #5228: Make functools.partial objects can now be pickled.

6180
Antoine Pitrou88909542009-06-29 13:54:42 +00006181- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
6182 regression tests in parallel, shortening the total runtime.
6183
Guilherme Polo2a998fa2009-06-21 17:40:07 +00006184- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6185 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
6186 the same behaviour as test_ttkguionly (and now also test_tk) which is to
6187 skip the tests if DISPLAY is defined but can't be used.
6188
R. David Murraya21e4ca2009-03-31 23:16:50 +00006189- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00006190 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00006191 from test support, which does the conversion.
6192
Guilherme Polo9de29af2009-01-28 20:40:48 +00006193- Issue #5083: New 'gui' resource for regrtest.
