Georg Brandlee449c42010-07-31 18:05:35 +00007What's New in Python 3.2 Alpha 2?
8=================================

11
12Core and Builtins
13-----------------
14
Daniel Stutzbacha606faa2010-08-31 19:51:07 +000015- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on
16 most platforms. Previously, it online inlined when using Microsoft
17 Visual C.
18
Benjamin Peterson33856de2010-08-30 14:41:20 +000019- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
20
Benjamin Peterson0e102062010-08-25 23:13:17 +000021- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
22
Daniel Stutzbach864078a2010-08-25 19:18:59 +000023- Issue #9684: Added a definition for SIZEOF_WCHAR_T to PC/pyconfig.h,
24 to match the pyconfig.h generated by configure on other systems.
25
Benjamin Peterson17689992010-08-24 03:26:23 +000026- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that

30 filesystem encoding.
31
Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +000032- Issue #5127: The C functions that access the Unicode Database now accept and
33 return characters from the full Unicode range, even on narrow unicode builds
34 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
35 in Python is that unicodedata.numeric() now returns the correct value for
36 large code points, and repr() may consider more characters as printable.
37
Victor Stinner6c00c142010-08-17 23:37:11 +000038- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

46
Nick Coghland26c18a2010-08-17 13:06:11 +000047- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching
48 for the module file to be executed with the -m command line option.
49
Victor Stinner79766632010-08-16 17:36:42 +000050- Issue #9599: Create PySys_FormatStdout() and PySys_FormatStderr() functions

52 sys.stderr.
53
Victor Stinner47fcb5b2010-08-13 23:59:58 +000054- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
55 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize();
56 str objects are output as-is.
57
Antoine Pitrou042b1282010-08-13 21:15:58 +000058- Issue #9203: Computed gotos are now enabled by default on supported
59 compilers (which are detected by the configure script). They can still
60 be disable selectively by specifying --without-computed-gotos.
61
Victor Stinner4a2b7a12010-08-13 14:03:48 +000062- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx()

69 shutdown.
70
Mark Dickinson388122d2010-08-04 20:56:28 +000071- Issue #9337: The str() of a float or complex number is now identical
72 to its repr().
73
Mark Dickinson5b65df72010-08-01 10:41:49 +000074- Issue #9416: Fix some issues with complex formatting where the
75 output with no type specifier failed to match the str output:
76
77 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
78 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

370
Victor Stinner8182b712010-07-28 00:40:58 +0000371- Issue #8991: convertbuffer() rejects discontigious buffers.
372
Antoine Pitrou1ac745b2010-07-11 12:12:00 +0000373- Issue #7616: Fix copying of overlapping memoryview slices with the Intel

377
Ezio Melotti57221d02010-07-01 07:32:02 +0000378- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +0000379 start byte and the continuation byte(s) are now considered invalid, instead of
380 the number of bytes specified by the start byte. E.g.:
381 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
382 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
383 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
384 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +0000385
Georg Brandl62069d32010-07-31 08:56:11 +0000386- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
387 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +0000388
Benjamin Peterson88968ad2010-06-25 19:30:21 +0000389- Be more specific in error messages about positional arguments.

Georg Brandl62069d32010-07-31 08:56:11 +0000398- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
399 dealing with unary minus applied to a constant. The removed code was mutating
400 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +0000402- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +0000403 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +0000404 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +0000405 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +0000406
Victor Stinner25e8ec42010-06-25 00:02:38 +0000407- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
408 "w*" format instead. Add tests for "w*" format.
409
Victor Stinner06e49dd2010-06-13 18:21:50 +0000410- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +0000411 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +0000412 string formats.
413
Georg Brandl62069d32010-07-31 08:56:11 +0000414- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +0000415 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
416 location of the raised exception.
417
Victor Stinner313a1202010-06-11 23:56:51 +0000418- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
419 filenames and enable os.fsencode().
420
Benjamin Peterson285a6892010-06-22 19:21:52 +0000421- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
422
Georg Brandl62069d32010-07-31 08:56:11 +0000423- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
424 interpreter with characters outside the Basic Multilingual Plane (higher than
425 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +0000426
Georg Brandl62069d32010-07-31 08:56:11 +0000427- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
428 TypeError instead of giving a DeprecationWarning when a float is parsed using
429 the 'L' code (for long long). (All other integer codes already raise
430 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +0000431
Victor Stinner600d3be2010-06-10 12:00:55 +0000432- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
433 enable shortcuts for upper case encoding name. Add also a shortcut for
434 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
435
Georg Brandl62069d32010-07-31 08:56:11 +0000436- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
437 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000438
439- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +0000440 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +0000441 like bytearray.
442
Georg Brandl62069d32010-07-31 08:56:11 +0000443- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +0000444 used anymore and it was never documented.
445
Georg Brandl62069d32010-07-31 08:56:11 +0000446- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +0000447
Georg Brandl62069d32010-07-31 08:56:11 +0000448- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
449 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +0000450
Georg Brandl62069d32010-07-31 08:56:11 +0000451- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
452 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
453 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
454 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +0000455
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000456- Issue #8748: Fix two issues with comparisons between complex and integer
457 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +0000458 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
459 (2) The comparison raised an OverflowError for large integers, leading to
460 unpredictable exceptions when combining integers and complex objects in sets
461 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000462
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000463- Issue #8766: Initialize _warnings module before importing the first module.

465
Victor Stinner9ca9c252010-05-19 16:53:30 +0000466- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +0000467 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +0000468 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +0000469
Georg Brandl62069d32010-07-31 08:56:11 +0000470- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
471 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +0000472
Victor Stinnerae6265f2010-05-15 16:27:27 +0000473- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
474 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +0000475 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000476 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000477
Victor Stinner59e62db2010-05-15 13:14:32 +0000478- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +0000479 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +0000480
Victor Stinnerb744ba12010-05-15 12:27:16 +0000481- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +0000482 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +0000483 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
484
Victor Stinner0964ee12010-04-30 16:48:45 +0000485- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +0000486 PyUnicode_FromString() to support surrogates in the filename and use the right
487 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +0000488
Georg Brandl8569e582010-05-19 20:57:08 +0000489- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
490
Georg Brandl62069d32010-07-31 08:56:11 +0000491- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000492
Benjamin Petersonfb886362010-04-24 18:21:17 +0000493- Issue #8419: Prevent the dict constructor from accepting non-string keyword
494 arguments.
495
Victor Stinner14284c22010-04-23 12:02:30 +0000496- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +0000497 indirectly Python signal handlers anymore because mywrite() ignores exceptions
498 (KeyboardInterrupt).

Antoine Pitrou3060c452010-08-13 16:27:38 +0000898 simply clearing the entire cache on overflow to forgetting the least recently
899 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +0000900 applications that use a lot of regular expressions and limits the impact of
901 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00001310- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1311 InvalidOperation instead of returning False. (Comparisons involving a quiet
1312 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1313 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00001315- Issue #2531: Comparison operations between floats and Decimal instances now
1316 return a result based on the numeric values of the operands; previously they
1317 returned an arbitrary result based on the relative ordering of id(float) and
1318 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
1319 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00001323- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00001324 argument `-` which tells it to read files to compile from stdin. Each line is

1333 Fractions instance now raise TypeError instead of returning True/False. This
1334 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1335 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00001378- The internals of the subprocess module on POSIX systems have been replaced by
1379 an extension module (_posixsubprocess) so that the fork()+exec() can be done
1380 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00001382- subprocess.Popen now has restore_signals and start_new_session features. The
1383 default of restore_signals=True is a new behavior compared to earlier Python
1384 versions. This means that signals such as SIGPIPE are not ignored by default
1385 in subprocesses launched by Python (Issue #1652).

1478 archive. The new implementation is significantly faster and can be wrapped in
1479 a :class:`io.BufferedReader` object for more speedups. It also solves an
1480 issue where interleaved calls to `read()` and `readline()` give wrong results.
1481 Patch by Nir Aides.

Brett Cannon69194272009-07-20 04:23:48 +00001816- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00001817 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00001872- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00001873 compared to other unix systems. In particular, os.getgroups() does not reflect
1874 any changes made using os.setgroups() but basicly always returns the same
1875 information as the id command. os.getgroups() can now return more than 16
1876 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00001877

Georg Brandl62069d32010-07-31 08:56:11 +00001901- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
1902 Prior to this change, timezone adjustment in utctimetuple() could produce
1903 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
1904 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00001906- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
1907 directive. When the ``%z`` directive is present in the format string, an
1908 aware ``datetime`` object is returned with ``tzinfo`` bound to a
1909 ``datetime.timezone`` instance constructed from the parsed offset. If both
1910 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
1911 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00001914 implementing ``datetime.tzinfo`` interface. Instances of the new class,
1915 ``datetime.timezone``, return fixed name and UTC offset from their
1916 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
1917 returns ``None``. A class attribute, ``utc`` contains an instance
1918 representing the UTC timezone. Original patch by Rafe Kaplan.

Mark Dickinson0381e3f2010-05-08 14:35:02 +00001943- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1944 calculating with integer arithmetic instead of float arithmetic internally):

Antoine Pitroue4501852009-05-14 18:55:55 +00002465- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
2466 library. This means, for example, that opening an UTF-16 text file in
2467 append mode doesn't add a BOM at the end of the file if the file isn't
2468 empty.

2518Core and Builtins
2519-----------------
2520
Mark Dickinson865e01a2009-05-07 16:37:01 +00002521- Issue #5914: Add new C API function PyOS_string_to_double, and
2522 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2523
Eric Smith741191f2009-05-06 13:08:15 +00002524- Issue #3382: float.__format__, complex.__format__, and %-formatting
2525 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2526 affects nan -> NAN and inf -> INF.
2527
Mark Hammond5a607a32009-05-06 08:04:54 +00002528- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2529 in all operations, including splitdrive, split, etc. splitunc() now issues
2530 a PendingDeprecation warning.
2531
Eric Smith63376222009-05-05 14:04:18 +00002532- Issue #5920: For float.__format__, change the behavior with the
2533 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2534 to be like 'g' but with at least one decimal point and with a
2535 default precision of 12. Previously, the behavior the same but with
2536 a default precision of 6. This more closely matches str(), and
2537 reduces surprises when adding alignment flags to the empty
2538 presentation type. This also affects the new complex.__format__ in
2539 the same way.
2540
Martin v. Löwis011e8422009-05-05 04:43:17 +00002541- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2542
R. David Murrayb18500d2009-05-04 22:59:07 +00002543- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2544 shadowed by classtype's, even if it was None. property now
2545 inserts the __doc__ into the subclass instance __dict__.
2546
Antoine Pitrou244651a2009-05-04 18:56:13 +00002547- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2548 sequences. Patch by Nick Barnes and Victor Stinner.
2549
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002550- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002551
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002552- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2553 received a new method, detach(). detach() disconnects the underlying stream
2554 from the buffer or text IO and returns it.
2555
Mark Dickinson33841c32009-05-01 15:37:04 +00002556- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2557 floats with absolute value over 1e50. Also remove length
2558 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2559 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002560
Eric Smith741191f2009-05-06 13:08:15 +00002561- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002562 format(complex(1, 2./3), '.5') now produces a sensible result.
2563
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002564- Issue #5864: Fix empty format code formatting for floats so that it
2565 never gives more than the requested number of significant digits.
2566
Eric Smith6dc46f52009-04-27 20:39:49 +00002567- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2568 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2569
Eric Smithcc32a112009-04-26 21:35:14 +00002570- Issue #5835: Deprecate PyOS_ascii_formatd.
2571
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002572- Issue #4971: Fix titlecase for characters that are their own
2573 titlecase, but not their own uppercase.
2574
Benjamin Peterson193152c2009-04-25 01:08:45 +00002575- Issue #5283: Setting __class__ in __del__ caused a segfault.
2576
Mark Dickinsonad476da2009-04-23 19:14:16 +00002577- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2578 z involves nans, infs or negative zeros.
2579
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002580- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002581
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002582- Issue #1869 (and many duplicates): make round(x, n) correctly
2583 rounded for a float x, by using the decimal <-> binary conversions
2584 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2585 consistently agrees with format(x, '.2f').
2586
Benjamin Petersonae937c02009-04-18 20:54:08 +00002587- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2588 some builtin types.
2589
Eric Smith0923d1d2009-04-16 20:16:10 +00002590- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2591
Eric Smith35e84722009-04-16 20:21:28 +00002592- Issue #5515: str.format() type 'n' combined with commas and leading
2593 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002594
2595- Implement PEP 378, Format Specifier for Thousands Separator, for
2596 floats.
2597
Mark Dickinson3370cce2009-04-17 22:40:53 +00002598- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002599 1e11, not 1e12. This avoids printing 13 significant digits in
2600 situations where only 12 of them are correct. Example problem
2601 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2602 long time.)
2603
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002604- Issue #1580: On most platforms, use a 'short' float repr: for a
2605 finite float x, repr(x) now outputs a string based on the shortest
2606 sequence of decimal digits that rounds to x. Previous behaviour was
2607 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002608 Another minor difference is that the new repr switches to
2609 exponential notation at 1e16 instead of the previous 1e17; this
2610 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002611
2612 There's a new sys attribute sys.float_repr_style, which takes
2613 the value 'short' to indicate that we're using short float repr,
2614 and 'legacy' if the short float repr isn't available for one
2615 reason or another.
2616
2617 The float repr change involves incorporating David Gay's 'perfect
2618 rounding' code into the Python core (it's in Python/dtoa.c). As a
2619 secondary consequence, all string-to-float and float-to-string
2620 conversions (including all float formatting operations) will be
2621 correctly rounded on these platforms.
2622
Georg Brandl5f90d792010-08-01 22:31:05 +00002623 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002624 this change does not apply.
2625
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002626- Issue #5759: float() didn't call __float__ on str subclasses.
2627
Georg Brandlabc38772009-04-12 15:51:51 +00002628- The string.maketrans() function is deprecated; there is a new static method
2629 maketrans() on the bytes and bytearray classes. This removes confusion about
2630 the types string.maketrans() is supposed to work with, and mirrors the
2631 methods available on the str class.
2632
R. David Murraydc6da8a2009-04-09 22:16:43 +00002633- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2634 its clarity and its speed.
2635
Matthias Klose091c7b12009-04-07 13:24:27 +00002636- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2637 to avoid compiler warnings.
2638
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002639- Issue #3739: The unicode-internal encoder now reports the number of characters
2640 consumed like any other encoder (instead of the number of bytes).

2654
Raymond Hettingereb816952009-05-29 01:22:18 +00002655- Issue #5150: IDLE's format menu now has an option to strip trailing

2657
Vinay Sajipaffbd872009-06-11 10:11:47 +00002658- Issue #5940: distutils.command.build_clib.check_library_list was not doing

2789
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002790- Issue #5604: non-ASCII characters in module name passed to
2791 imp.find_module() were converted to UTF-8 while the path is
2792 converted to the default filesystem encoding, causing nonsense.

2795
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002796- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2797 the end sys.path, for compatibility with the system install of Python.
2798
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002799- Issue #4688: Add a heuristic so that tuples and dicts containing only
2800 untrackable objects are not tracked by the garbage collector. This can
2801 reduce the size of collections and therefore the garbage collection overhead
2802 on long-running programs, depending on their particular use of datatypes.
2803
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002804- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

2816 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2817 and sizeof(Py_UNICODE) == 2.
2818
Eric Smith8ec90442009-03-14 12:29:34 +00002819- Issue #5237: Allow auto-numbered fields in str.format(). For

2821
Antoine Pitrou652e7072009-03-13 19:25:20 +00002822- Issue #5392: when a very low recursion limit was set, the interpreter would
2823 abort with a fatal error after the recursion limit was hit twice.
2824
Matthias Klose042f1332009-04-04 14:32:42 +00002825- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2871
Lars Gustäbel42e00912009-03-22 20:34:29 +00002872- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2873 forever on incomplete input. That caused tarfile.open() to hang when used
2874 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2875 partial bzip2 compressed data.
2876
Mark Dickinson79f52032009-03-17 23:12:51 +00002877- Issue #2110: Add support for thousands separator and 'n' type

2945 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2946 evaluation loop is compiled with a new dispatch mechanism which gives
2947 speedups of up to 20%, depending on the system, on various benchmarks.

2963 to str, bytes and bytearray could be optimized away by the compiler, letting
2964 the interpreter segfault instead of raising an error.
2965
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002966- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2992 flag to work properly. Furthermore, when specifying -u, the text stdout
2993 and stderr streams have line-by-line buffering enabled (the default being
2994 to buffer arbitrary chunks of data).
2995
Raymond Hettinger35631532009-01-09 03:58:09 +00002996- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2997 instead of ints (reducing its size from 4 to 8 times thereby reducing

2999
Antoine Pitroud35cbf62009-01-06 19:02:24 +00003000- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
3001 an existing .py counterpart, override the co_filename attributes of all
3002 code objects if the original filename is obsolete (which can happen if the
3003 file has been renamed, moved, or if it is accessed through different paths).
3004 Patch by Ziga Seilnacht and Jean-Paul Calderone.
3005
Antoine Pitrouc3b39242009-01-03 16:59:18 +00003006- Issue #4580: Fix slicing of memoryviews when the item size is greater than
3007 one byte. Also fixes the meaning of len() so that it returns the number of
3008 items, rather than the size in bytes.
3009
Martin v. Löwis5c88d812009-01-02 20:47:48 +00003010- Issue #4075: Use OutputDebugStringW in Py_FatalError.

3023
Georg Brandlccc47b62008-12-28 11:44:14 +00003024- Issue #4759: None is now allowed as the first argument of

3078 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00003398- Issue #5008: When a file is opened in append mode with the new IO library,
3399 do an explicit seek to the end of file (so that e.g. tell() returns the
