12Core and Builtins
13-----------------
14
Benjamin Peterson17689992010-08-24 03:26:23 +000015- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that
16 occur during attribute lookup are now propagated to the caller.
17
Victor Stinner94908bb2010-08-18 21:23:25 +000018- Issue #8622: Add PYTHONFSENCODING environment variable to override the
19 filesystem encoding.
20
Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +000021- Issue #5127: The C functions that access the Unicode Database now accept and
22 return characters from the full Unicode range, even on narrow unicode builds
23 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
24 in Python is that unicodedata.numeric() now returns the correct value for
25 large code points, and repr() may consider more characters as printable.
26
Victor Stinner6c00c142010-08-17 23:37:11 +000027- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
28 as a unicode object, instead of a byte string. Function needed to support
29 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
30 function.
31
Victor Stinner6961bd62010-08-17 22:26:51 +000032- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().
33
Antoine Pitrou671b4d92010-08-17 17:55:07 +000034- Issue #9612: The set object is now 64-bit clean under Windows.
35
Nick Coghland26c18a2010-08-17 13:06:11 +000036- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching
37 for the module file to be executed with the -m command line option.
38
Victor Stinner79766632010-08-16 17:36:42 +000039- Issue #9599: Create PySys_FormatStdout() and PySys_FormatStderr() functions
40 to write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
41 sys.stderr.
42
Victor Stinner47fcb5b2010-08-13 23:59:58 +000043- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
44 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize();
45 str objects are output as-is.
46
Antoine Pitrou042b1282010-08-13 21:15:58 +000047- Issue #9203: Computed gotos are now enabled by default on supported
48 compilers (which are detected by the configure script). They can still
49 be disable selectively by specifying --without-computed-gotos.
50
Victor Stinner4a2b7a12010-08-13 14:03:48 +000051- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx()
52 but use PyUnicode_FromFormatV() to format the warning message.
53
Florent Xiclunaeb6f3ea2010-08-08 22:07:16 +000054- Issue #8530: Prevent stringlib fastsearch from reading beyond the front
55 of an array.
56
Antoine Pitroubddc9fe2010-08-08 20:46:42 +000057- Issue #5319: Print an error if flushing stdout fails at interpreter
58 shutdown.
59
Mark Dickinson388122d2010-08-04 20:56:28 +000060- Issue #9337: The str() of a float or complex number is now identical
61 to its repr().
62
Mark Dickinson5b65df72010-08-01 10:41:49 +000063- Issue #9416: Fix some issues with complex formatting where the
64 output with no type specifier failed to match the str output:
65
66 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
67 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

335Core and Builtins
336-----------------
337
Victor Stinner8182b712010-07-28 00:40:58 +0000338- Issue #8991: convertbuffer() rejects discontigious buffers.
339
Antoine Pitrou1ac745b2010-07-11 12:12:00 +0000340- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
341 compiler.

344
Ezio Melotti57221d02010-07-01 07:32:02 +0000345- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +0000346 start byte and the continuation byte(s) are now considered invalid, instead of
347 the number of bytes specified by the start byte. E.g.:
348 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
349 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
350 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
351 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +0000353- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
354 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +0000355
Benjamin Peterson88968ad2010-06-25 19:30:21 +0000356- Be more specific in error messages about positional arguments.

Georg Brandl62069d32010-07-31 08:56:11 +0000365- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
366 dealing with unary minus applied to a constant. The removed code was mutating
367 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +0000368
Victor Stinner554f3f02010-06-16 23:33:54 +0000369- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +0000370 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +0000371 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +0000372 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +0000373
Victor Stinner25e8ec42010-06-25 00:02:38 +0000374- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
375 "w*" format instead. Add tests for "w*" format.
376
Victor Stinner06e49dd2010-06-13 18:21:50 +0000377- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +0000378 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +0000379 string formats.
380
Georg Brandl62069d32010-07-31 08:56:11 +0000381- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +0000382 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
383 location of the raised exception.
384
Victor Stinner313a1202010-06-11 23:56:51 +0000385- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
386 filenames and enable os.fsencode().
387
Benjamin Peterson285a6892010-06-22 19:21:52 +0000388- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
389
Georg Brandl62069d32010-07-31 08:56:11 +0000390- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
391 interpreter with characters outside the Basic Multilingual Plane (higher than
392 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +0000393
Georg Brandl62069d32010-07-31 08:56:11 +0000394- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
395 TypeError instead of giving a DeprecationWarning when a float is parsed using
396 the 'L' code (for long long). (All other integer codes already raise
397 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +0000398
Victor Stinner600d3be2010-06-10 12:00:55 +0000399- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
400 enable shortcuts for upper case encoding name. Add also a shortcut for
401 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
402
Georg Brandl62069d32010-07-31 08:56:11 +0000403- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
404 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000405
406- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +0000407 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000408 like bytearray.
409
Georg Brandl62069d32010-07-31 08:56:11 +0000410- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +0000411 used anymore and it was never documented.
412
Georg Brandl62069d32010-07-31 08:56:11 +0000413- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +0000414
Georg Brandl62069d32010-07-31 08:56:11 +0000415- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
416 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +0000417
Georg Brandl62069d32010-07-31 08:56:11 +0000418- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
419 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
420 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
421 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +0000422
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000423- Issue #8748: Fix two issues with comparisons between complex and integer
424 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +0000425 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
426 (2) The comparison raised an OverflowError for large integers, leading to
427 unpredictable exceptions when combining integers and complex objects in sets
428 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000429
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000430- Issue #8766: Initialize _warnings module before importing the first module.
431 Fix a crash if an empty directory called "encodings" exists in sys.path.
432
Victor Stinner9ca9c252010-05-19 16:53:30 +0000433- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +0000434 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +0000435 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +0000436
Georg Brandl62069d32010-07-31 08:56:11 +0000437- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
438 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +0000439
Victor Stinnerae6265f2010-05-15 16:27:27 +0000440- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
441 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +0000442 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000443 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000444
Victor Stinner59e62db2010-05-15 13:14:32 +0000445- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +0000446 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +0000447
Victor Stinnerb744ba12010-05-15 12:27:16 +0000448- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +0000449 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +0000450 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
451
Victor Stinner0964ee12010-04-30 16:48:45 +0000452- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +0000453 PyUnicode_FromString() to support surrogates in the filename and use the right
454 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +0000455
Georg Brandl8569e582010-05-19 20:57:08 +0000456- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
457
Georg Brandl62069d32010-07-31 08:56:11 +0000458- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000459
Benjamin Petersonfb886362010-04-24 18:21:17 +0000460- Issue #8419: Prevent the dict constructor from accepting non-string keyword
461 arguments.
462
Victor Stinner14284c22010-04-23 12:02:30 +0000463- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +0000464 indirectly Python signal handlers anymore because mywrite() ignores exceptions
465 (KeyboardInterrupt).

Victor Stinner31be90b2010-04-22 19:38:16 +0000469
Georg Brandl62069d32010-07-31 08:56:11 +0000470- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
471 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +0000472
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000473- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +0000474 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

Georg Brandl62069d32010-07-31 08:56:11 +0000558 where the right hand operand is a set of constants, by turning the set into a
559 frozenset and pre-building it as a constant. The comparison operation is made
560 against the constant instead of building a new set each time it is executed (a
561 similar optimization already existed which turned a list of constants into a
562 pre-built tuple). Patch and additional tests by Dave Malcolm.

868 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00001240- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00001241 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00001242 relies on the system threading library, so as to avoid a semi-busy wait loop.

R. David Murrayb2416e52010-04-12 16:58:02 +00001248- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00001249 filename and date, conforming to the 'standards' they were originally designed

Georg Brandl62069d32010-07-31 08:56:11 +00001268- Issue #8257: The Decimal construct now accepts a float instance directly,
1269 converting that float to a Decimal of equal value:

Georg Brandl62069d32010-07-31 08:56:11 +00001277- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1278 InvalidOperation instead of returning False. (Comparisons involving a quiet
1279 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1280 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00001282- Issue #2531: Comparison operations between floats and Decimal instances now
1283 return a result based on the numeric values of the operands; previously they
1284 returned an arbitrary result based on the relative ordering of id(float) and
1285 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
1286 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00001287
Raymond Hettinger9c01e442010-04-03 10:32:58 +00001288- Added a subtract() method to collections.Counter().
1289
Barry Warsawd5f9bf52010-03-31 21:36:22 +00001290- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00001291 argument `-` which tells it to read files to compile from stdin. Each line is
1292 read on demand and the named file is compiled immediately. (Original patch by
1293 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00001295- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00001299- Comparisons using one of <, <=, >, >= between a complex instance and a
1300 Fractions instance now raise TypeError instead of returning True/False. This
1301 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1302 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00001345- The internals of the subprocess module on POSIX systems have been replaced by
1346 an extension module (_posixsubprocess) so that the fork()+exec() can be done
1347 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00001348
Georg Brandl62069d32010-07-31 08:56:11 +00001349- subprocess.Popen now has restore_signals and start_new_session features. The
1350 default of restore_signals=True is a new behavior compared to earlier Python
1351 versions. This means that signals such as SIGPIPE are not ignored by default
1352 in subprocesses launched by Python (Issue #1652).

1439 position when calling `truncate()`. It would previously change the file
1440 position to the given argument, which goes against the tradition of

1445 archive. The new implementation is significantly faster and can be wrapped in
1446 a :class:`io.BufferedReader` object for more speedups. It also solves an
1447 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00001839- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00001840 compared to other unix systems. In particular, os.getgroups() does not reflect
1841 any changes made using os.setgroups() but basicly always returns the same
1842 information as the id command. os.getgroups() can now return more than 16
1843 groups on MacOSX.

1869 Prior to this change, timezone adjustment in utctimetuple() could produce
1870 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

Georg Brandl62069d32010-07-31 08:56:11 +00002176- Issue #6551: test_zipimport could import and then destroy some modules of the
2177 encodings package, which would make other tests fail further down the road
2178 because the internally cached encoders and decoders would point to empty

2196 threads could return successfully while some Thread objects were still
2197 referenced. This also introduces a new private function:

2205
R. David Murray0bc11ae2009-10-18 22:18:17 +00002206- Issue #7058: Added save/restore for things like sys.argv and cwd to
Georg Brandl62069d32010-07-31 08:56:11 +00002207 runtest_inner in regrtest, with warnings if the called test modifies them, and

Benjamin Petersonbd35b032009-04-04 23:16:41 +00002484
2485Core and Builtins
2486-----------------
2487
Mark Dickinson865e01a2009-05-07 16:37:01 +00002488- Issue #5914: Add new C API function PyOS_string_to_double, and
2489 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2490
Eric Smith741191f2009-05-06 13:08:15 +00002491- Issue #3382: float.__format__, complex.__format__, and %-formatting
2492 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2493 affects nan -> NAN and inf -> INF.
2494
Mark Hammond5a607a32009-05-06 08:04:54 +00002495- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2496 in all operations, including splitdrive, split, etc. splitunc() now issues
2497 a PendingDeprecation warning.
2498
Eric Smith63376222009-05-05 14:04:18 +00002499- Issue #5920: For float.__format__, change the behavior with the
2500 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2501 to be like 'g' but with at least one decimal point and with a
2502 default precision of 12. Previously, the behavior the same but with
2503 a default precision of 6. This more closely matches str(), and
2504 reduces surprises when adding alignment flags to the empty
2505 presentation type. This also affects the new complex.__format__ in
2506 the same way.
2507
Martin v. Löwis011e8422009-05-05 04:43:17 +00002508- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2509
R. David Murrayb18500d2009-05-04 22:59:07 +00002510- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2511 shadowed by classtype's, even if it was None. property now
2512 inserts the __doc__ into the subclass instance __dict__.
2513
Antoine Pitrou244651a2009-05-04 18:56:13 +00002514- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2515 sequences. Patch by Nick Barnes and Victor Stinner.
2516
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002517- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002518
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002519- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2520 received a new method, detach(). detach() disconnects the underlying stream
2521 from the buffer or text IO and returns it.
2522
Mark Dickinson33841c32009-05-01 15:37:04 +00002523- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2524 floats with absolute value over 1e50. Also remove length
2525 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2526 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002527
Eric Smith741191f2009-05-06 13:08:15 +00002528- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002529 format(complex(1, 2./3), '.5') now produces a sensible result.
2530
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002531- Issue #5864: Fix empty format code formatting for floats so that it
2532 never gives more than the requested number of significant digits.
2533
Eric Smith6dc46f52009-04-27 20:39:49 +00002534- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2535 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2536
Eric Smithcc32a112009-04-26 21:35:14 +00002537- Issue #5835: Deprecate PyOS_ascii_formatd.
2538
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002539- Issue #4971: Fix titlecase for characters that are their own
2540 titlecase, but not their own uppercase.
2541
Benjamin Peterson193152c2009-04-25 01:08:45 +00002542- Issue #5283: Setting __class__ in __del__ caused a segfault.
2543
Mark Dickinsonad476da2009-04-23 19:14:16 +00002544- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2545 z involves nans, infs or negative zeros.
2546
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002547- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002548
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002549- Issue #1869 (and many duplicates): make round(x, n) correctly
2550 rounded for a float x, by using the decimal <-> binary conversions
2551 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2552 consistently agrees with format(x, '.2f').
2553
Benjamin Petersonae937c02009-04-18 20:54:08 +00002554- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2555 some builtin types.
2556
Eric Smith0923d1d2009-04-16 20:16:10 +00002557- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2558
Eric Smith35e84722009-04-16 20:21:28 +00002559- Issue #5515: str.format() type 'n' combined with commas and leading
2560 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002561
2562- Implement PEP 378, Format Specifier for Thousands Separator, for
2563 floats.
2564
Mark Dickinson3370cce2009-04-17 22:40:53 +00002565- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002566 1e11, not 1e12. This avoids printing 13 significant digits in
2567 situations where only 12 of them are correct. Example problem
2568 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2569 long time.)
2570
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002571- Issue #1580: On most platforms, use a 'short' float repr: for a
2572 finite float x, repr(x) now outputs a string based on the shortest
2573 sequence of decimal digits that rounds to x. Previous behaviour was
2574 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002575 Another minor difference is that the new repr switches to
2576 exponential notation at 1e16 instead of the previous 1e17; this
2577 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002578
2579 There's a new sys attribute sys.float_repr_style, which takes
2580 the value 'short' to indicate that we're using short float repr,
2581 and 'legacy' if the short float repr isn't available for one
2582 reason or another.
2583
2584 The float repr change involves incorporating David Gay's 'perfect
2585 rounding' code into the Python core (it's in Python/dtoa.c). As a
2586 secondary consequence, all string-to-float and float-to-string
2587 conversions (including all float formatting operations) will be
2588 correctly rounded on these platforms.
2589
Georg Brandl5f90d792010-08-01 22:31:05 +00002590 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002591 this change does not apply.
2592
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002593- Issue #5759: float() didn't call __float__ on str subclasses.
2594
Georg Brandlabc38772009-04-12 15:51:51 +00002595- The string.maketrans() function is deprecated; there is a new static method
2596 maketrans() on the bytes and bytearray classes. This removes confusion about
2597 the types string.maketrans() is supposed to work with, and mirrors the
2598 methods available on the str class.
2599
R. David Murraydc6da8a2009-04-09 22:16:43 +00002600- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2601 its clarity and its speed.
2602
Matthias Klose091c7b12009-04-07 13:24:27 +00002603- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2604 to avoid compiler warnings.
2605
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002606- Issue #3739: The unicode-internal encoder now reports the number of characters
2607 consumed like any other encoder (instead of the number of bytes).

Brett Cannon0759dd62009-04-01 18:13:07 +00002752- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
2753
Georg Brandlab6f2f62009-03-31 04:16:10 +00002754- Fix a segfault when running test_exceptions with coverage, caused by
2755 insufficient checks in accessors of Exception.__context__.
2756
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002757- Issue #5604: non-ASCII characters in module name passed to
2758 imp.find_module() were converted to UTF-8 while the path is
2759 converted to the default filesystem encoding, causing nonsense.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002763- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2764 the end sys.path, for compatibility with the system install of Python.
2765
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002766- Issue #4688: Add a heuristic so that tuples and dicts containing only
2767 untrackable objects are not tracked by the garbage collector. This can
2768 reduce the size of collections and therefore the garbage collection overhead
2769 on long-running programs, depending on their particular use of datatypes.
2770
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002771- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
2772 improve its performance. Long divisions and remainder operations
2773 are now between 50% and 150% faster.
2774
Mark Dickinsonbd792642009-03-18 20:06:12 +00002775- Issue #4258: Make it possible to use base 2**30 instead of base
2776 2**15 for the internal representation of integers, for performance
2777 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2778 --enable-big-digits option to configure, which overrides the
2779 default. Add sys.int_info structseq to provide information about
2780 the internal format.
2781
Mark Dickinson081dfee2009-03-18 14:47:41 +00002782- Issue #4474: PyUnicode_FromWideChar now converts characters outside
2783 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2784 and sizeof(Py_UNICODE) == 2.
2785
Eric Smith8ec90442009-03-14 12:29:34 +00002786- Issue #5237: Allow auto-numbered fields in str.format(). For

2788
Antoine Pitrou652e7072009-03-13 19:25:20 +00002789- Issue #5392: when a very low recursion limit was set, the interpreter would
2790 abort with a fatal error after the recursion limit was hit twice.
2791
Matthias Klose042f1332009-04-04 14:32:42 +00002792- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2838
Lars Gustäbel42e00912009-03-22 20:34:29 +00002839- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2840 forever on incomplete input. That caused tarfile.open() to hang when used
2841 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Mark Dickinsonb40b9472009-03-29 16:58:21 +00002863 struct.error instead of returning b'\xff\xff\xff\xff'. The
2864 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

Mark Dickinson87ec0852009-02-09 17:15:59 +00002892- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2893 it now forces its argument to double before testing for infinity.
2894
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002895- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2896 returns a non-number type.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002904
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002905- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002906 were suppressing all exceptions. These include list() and bytearray().
2907
Mark Dickinson1124e712009-01-28 21:25:58 +00002908- Issue #4707: round(x, n) now returns an integer if x is an integer.
2909 Previously it returned a float.
2910
Antoine Pitroub52ec782009-01-25 16:34:23 +00002911- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2912 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2913 evaluation loop is compiled with a new dispatch mechanism which gives
2914 speedups of up to 20%, depending on the system, on various benchmarks.
2915
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002916- Issue #4874: Most builtin decoders now reject unicode input.

2922
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002923- Issue #4838: When a module is deallocated, free the memory backing the
2924 optional module state data.
2925
Mark Dickinson8055afd2009-01-17 10:04:45 +00002926- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2927 type to (void *).
2928
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002929- Issue #4935: The overflow checking code in the expandtabs() method common
2930 to str, bytes and bytearray could be optimized away by the compiler, letting
2931 the interpreter segfault instead of raising an error.
2932
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002933- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2934 __next__ method.
2935
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002936- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

2943
Antoine Pitrouab868312009-01-10 15:40:25 +00002944- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2945 common cases are optimized thanks to a dedicated fast path and a moderate
2946 amount of loop unrolling.
2947
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002948- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2949 collecting the oldest generation) so that allocating lots of objects without
2950 destroying them does not show quadratic performance. Based on a proposal by
2951 Martin von Löwis at
2952 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2953
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002954- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002955 having been closed (for instance, a read() call could return some
2956 previously buffered data). Patch by Dmitry Vasiliev.
2957
Antoine Pitrou05608432009-01-09 18:53:14 +00002958- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2959 flag to work properly. Furthermore, when specifying -u, the text stdout
2960 and stderr streams have line-by-line buffering enabled (the default being
2961 to buffer arbitrary chunks of data).
2962
Raymond Hettinger35631532009-01-09 03:58:09 +00002963- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2964 instead of ints (reducing its size from 4 to 8 times thereby reducing
2965 Python's overall memory).
2966
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002967- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2968 an existing .py counterpart, override the co_filename attributes of all
2969 code objects if the original filename is obsolete (which can happen if the
2970 file has been renamed, moved, or if it is accessed through different paths).
2971 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2972
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002973- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2974 one byte. Also fixes the meaning of len() so that it returns the number of
2975 items, rather than the size in bytes.
2976
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002977- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2978
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002979- Issue #4747: When the terminal does not use utf-8, executing a script with
2980 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2981
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002982- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002983 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002984
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002985- Issue #3680: Reference cycles created through a dict, set or deque iterator
2986 did not get collected.
2987
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002988- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2989 where the tp_hash and tp_dict slots are both NULL.
2990
Georg Brandlccc47b62008-12-28 11:44:14 +00002991- Issue #4759: None is now allowed as the first argument of
2992 bytearray.translate(). It was always allowed for bytes.translate().
2993
Skip Montanaro80072cb2008-12-23 03:51:14 +00002994- Added test case to ensure attempts to read from a file opened for writing
2995 fail.
2996
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002997- Issue #3106: Speedup some comparisons (str/str and int/int).

3001
Antoine Pitrou621601a2008-12-17 23:18:19 +00003002- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
3003 print elapsed times, not only when some objects are uncollectable /
3004 unreachable. Original patch by Neil Schemenauer.
3005
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00003006- Issue #3439: Add a bit_length method to int.
3007
Mark Dickinsonda2706b2008-12-11 18:03:03 +00003008- Issue #2173: When getting device encoding, check that return value of
3009 nl_langinfo is not the empty string. This was causing silent build
3010 failures on OS X.
3011
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00003012- Issue #4597: Fixed several opcodes that weren't always propagating
3013 exceptions.
3014
3015- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00003016 context manager returns a value that cannot be converted to a bool.
3017
Mark Dickinsonfd24b322008-12-06 15:33:31 +00003018- Issue #4445: Replace "sizeof(PyBytesObject)" with
3019 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
3020 bytes instances. On a typical machine this saves 3 bytes of memory
3021 (on average) per allocation of a bytes instance.
3022
Christian Heimesa872de52008-12-05 08:26:55 +00003023- Issue #4533: File read operation was dreadfully slow due to a slowly
3024 growing read buffer. Fixed by using the same growth rate algorithm as
3025 Python 2.x.
3026
Antoine Pitrou5504e892008-12-06 21:27:53 +00003027- Issue #4509: Various issues surrounding resize of bytearray objects to
3028 which there are buffer exports (e.g. memoryview instances).
3029
Georg Brandlf9734072008-12-07 15:30:06 +00003030- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
3031 method on file objects with closefd=False. The file descriptor is still
3032 kept open but the file object behaves like a closed file. The ``FileIO``

3627 or decompress several streams at once on multi-CPU systems. Also, the GIL
3628 is now released when computing the CRC of a large buffer. Patch by ebfe.
3629
Georg Brandlb1441c72009-01-03 22:33:39 +00003630- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.

Antoine Pitrou88909542009-06-29 13:54:42 +00003647- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3648 regression tests in parallel, shortening the total runtime.
3649
Guilherme Polo2a998fa2009-06-21 17:40:07 +00003650- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3651 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
3652 the same behaviour as test_ttkguionly (and now also test_tk) which is to
3653 skip the tests if DISPLAY is defined but can't be used.
3654
R. David Murraya21e4ca2009-03-31 23:16:50 +00003655- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00003656 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00003657 from test support, which does the conversion.
3658
Guilherme Polo9de29af2009-01-28 20:40:48 +00003659- Issue #5083: New 'gui' resource for regrtest.
