Gregory P. Smith9564e4c2012-01-21 14:50:11 -080022- Issue #8052: The posix subprocess module would take a long time closing
23 all possible file descriptors in the child process rather than just open
24 file descriptors. It now closes only the open fds if possible for the
25 default close_fds=True behavior.
26
Meador Inge33880602012-01-15 19:15:36 -060027- Issue #13629: Renumber the tokens in token.h so that they match the indexes

Antoine Pitrou5136ac02012-01-13 18:52:16 +010035- Issue #13645: pyc files now contain the size of the corresponding source
36 code, to avoid timestamp collisions (especially on filesystems with a low
37 timestamp resolution) when checking for freshness of the bytecode.
38
Nick Coghlan1f7ce622012-01-13 21:43:40 +100039- PEP 380, Issue #11682: Add "yield from <x>" to support easy delegation to
40 subgenerators (initial patch by Greg Ewing, integration into 3.3 by
41 Renaud Blanch, Ryan Kelly, Zbigniew Jędrzejewski-Szmek and Nick Coghlan)
42

56 objects. Initial patch by Matthias Troffaes.
57
Antoine Pitroue0e27352011-12-15 14:31:28 +010058- Fix OSError.__init__ and OSError.__new__ so that each of them can be
59 overriden and take additional arguments (followup to issue #12555).
60
Antoine Pitrou2e872082011-12-15 14:15:31 +010061- Fix the fix for issue #12149: it was incorrect, although it had the side

77 sys module entries are now set to None (instead of an unusable file object).
78
Antoine Pitrouf0effe62011-11-26 01:11:02 +010079- Issue #11849: Ensure that free()d memory arenas are really released

81 Charles-François Natali.
82
Victor Stinnercad939b2011-11-25 20:11:54 +010083- Issue #13452: PyUnicode_EncodeDecimal() doesn't support error handlers
Victor Stinner6345be92011-11-25 20:09:01 +010084 different than "strict" anymore. The caller was unable to compute the
85 size of the output buffer: it depends on the error handler.
86

101
Antoine Pitrou56a220a2011-11-16 00:56:10 +0100102- Issue #13393: BufferedReader.read1() now asks the full requested size to
103 the raw stream instead of limiting itself to the buffer size.
104

106
Antoine Pitrou5418ee02011-11-15 01:42:21 +0100107- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
108 already accepts them).
109
Antoine Pitrou9a812cb2011-11-15 00:00:12 +0100110- Issue #13389: Full garbage collection passes now clear the freelists for
111 list and dict objects. They already cleared other freelists in the
112 interpreter.
113

Brian Curtin304a1652011-11-07 16:30:01 -0600115 to os.utime, os.lutimes, os.futimes, os.futimens, os.futimesat, in
116 order to update to the current time. Also added keyword argument
117 handling to os.utimensat in order to remove the need for explicit None.
Brian Curtin52fbea12011-11-06 13:41:17 -0600118

Ned Deily657b2de2011-06-28 19:51:30 -07001113- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1114 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1115 interpreter process. This could cause failures in non-Distutils subprocesses
1116 and was unreliable since tests or user programs could modify the interpreter
1117 environment after Distutils set it. Instead, have Distutils set the the
1118 deployment target only in the environment of each build subprocess. It is
1119 still possible to globally override the default by setting
1120 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1121 greater or equal to the default value, the value with which the interpreter

2222 files in binary mode, using the email package's binary support to parse
2223 arbitrary email messages. StringIO and text file input is deprecated,
2224 and string input fails early if non-ASCII characters are used, where
Éric Araujoac4e58e2011-01-29 20:32:11 +00002225 previously it would fail when the email was processed in a later step.

Antoine Pitrou305bc9e2011-01-20 21:07:24 +00002269 filenames, at bootstrap, if the codec registry is not ready yet. It is still

2283 of HTTP 1.1.
Steven Bethardb0270112011-01-24 21:02:50 +00002284
2285- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00002286 encodes headers with iso-8859-1 (latin1) encoding. It was already doing

Georg Brandl255abdd2011-01-16 14:17:26 +00002385 continuation line in the formatted value has no leading white space and looks
2386 like a header. Since Generator uses Header to format all headers, this check
2387 is made for all headers in any serialized message at serialization time. This
2388 provides protection against header injection attacks.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00003046 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00003047 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00003048 encoding and to encode command line arguments on this OS.

3432
Georg Brandl27a28582010-10-10 09:49:21 +00003433- All SyntaxErrors now have a column offset and therefore a caret when the error

3443 with a non-empty format string. This is an effort to future-proof user
3444 code. If a derived class does not currently implement __format__ but later
3445 adds its own __format__, it would most likely break user code that had
3446 supplied a format string. This will be changed to a DeprecationWaring in
3447 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00003449- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

3451 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

3454 functions from the libc caused the methods .upper() and lower() to become
3455 locale aware and created subtly wrong results.
3456
Georg Brandl27a28582010-10-10 09:49:21 +00003457- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Victor Stinner1205f272010-09-11 00:54:47 +00003459
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003460- Issue #4617: Previously it was illegal to delete a name from the local
3461 namespace if it occurs as a free variable in a nested block. This limitation
3462 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3463
Georg Brandl27a28582010-10-10 09:49:21 +00003464- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3465 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3466 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3467 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00003502- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003503 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003504 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003505 replacement for old handle_accept() and avoids the user to call accept()
3506 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00003530 retry the select() loop instead of bailing out. This is because select() can
3531 incorrectly report a socket as ready for reading (for example, if it received
3532 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00003579 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003612- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003613 it possible for the user to create self-referencing ordered dictionaries which
3614 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003615 approach of using weakref proxies so that reference cycles never get created
3616 in the first place.
3617
Victor Stinnercb043522010-09-10 23:49:04 +00003618- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00003622- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3623 environment variable to set the filesystem encoding at Python startup.
3624 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3625 reencode all filenames in all objects.

3636
Georg Brandl27a28582010-10-10 09:49:21 +00003637- Issue #9707: Rewritten reference implementation of threading.local which is
3638 friendlier towards reference cycles. This change is not normally visible
3639 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003640
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003641- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3642 still return the id of the parent process after it has exited. This process
3643 id may even have been reused by another unrelated process.
3644
Georg Brandl27a28582010-10-10 09:49:21 +00003645- Issue #9792: In case of connection failure, socket.create_connection() would
3646 swallow the exception and raise a new one, making it impossible to fetch the
3647 original errno, or to filter timeout errors. Now the original error is
3648 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003654- Updates to the random module:
3655
Georg Brandl27a28582010-10-10 09:49:21 +00003656 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00003659 * Update the seed() method to use all of the bits in a string instead of just
3660 the hash value. This makes better use of the seed value and assures the
3661 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003662
Georg Brandl27a28582010-10-10 09:49:21 +00003663 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3664 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3665 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003666
3667 * Improved documentation of arguments to randrange(). Issue #9379.

3688 guaranteed to exist in all Python implementations and the names of hash
3689 algorithms available in the current process.

3818 return characters from the full Unicode range, even on narrow unicode builds
3819 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3820 in Python is that unicodedata.numeric() now returns the correct value for
3821 large code points, and repr() may consider more characters as printable.
3822
Victor Stinner6c00c142010-08-17 23:37:11 +00003823- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Victor Stinner47fcb5b2010-08-13 23:59:58 +00003839- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00003840 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
3841 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00003847- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3848 use PyUnicode_FromFormatV() to format the warning message.

3856 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003857
Georg Brandl649971e2010-09-05 17:06:50 +00003858- Issue #9416: Fix some issues with complex formatting where the output with no
3859 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003860
3861 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3862 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

4427 parsing certain long numeric strings corresponding to subnormal values, (3) a
4428 memory leak for some values large enough to cause overflow, and (4) a number
4429 of flaws that could lead to incorrectly rounded results.

Georg Brandl62069d32010-07-31 08:56:11 +00005124- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandl62069d32010-07-31 08:56:11 +00005133- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5134 InvalidOperation instead of returning False. (Comparisons involving a quiet
5135 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5136 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00005138- Issue #2531: Comparison operations between floats and Decimal instances now
5139 return a result based on the numeric values of the operands; previously they
5140 returned an arbitrary result based on the relative ordering of id(float) and
5141 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
5142 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00005143
Raymond Hettinger9c01e442010-04-03 10:32:58 +00005144- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00005146- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00005147 argument `-` which tells it to read files to compile from stdin. Each line is
5148 read on demand and the named file is compiled immediately. (Original patch by
5149 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00005155- Comparisons using one of <, <=, >, >= between a complex instance and a
5156 Fractions instance now raise TypeError instead of returning True/False. This
5157 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5158 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00005201- The internals of the subprocess module on POSIX systems have been replaced by
5202 an extension module (_posixsubprocess) so that the fork()+exec() can be done
5203 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00005204
Georg Brandl62069d32010-07-31 08:56:11 +00005205- subprocess.Popen now has restore_signals and start_new_session features. The
5206 default of restore_signals=True is a new behavior compared to earlier Python
5207 versions. This means that signals such as SIGPIPE are not ignored by default
5208 in subprocesses launched by Python (Issue #1652).

5295 position when calling `truncate()`. It would previously change the file
5296 position to the given argument, which goes against the tradition of

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005701- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005702 compared to other unix systems. In particular, os.getgroups() does not reflect
5703 any changes made using os.setgroups() but basicly always returns the same
5704 information as the id command. os.getgroups() can now return more than 16
5705 groups on MacOSX.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00006349
6350Core and Builtins
6351-----------------
6352
Mark Dickinson865e01a2009-05-07 16:37:01 +00006353- Issue #5914: Add new C API function PyOS_string_to_double, and
6354 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
6355
Eric Smith741191f2009-05-06 13:08:15 +00006356- Issue #3382: float.__format__, complex.__format__, and %-formatting
6357 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
6358 affects nan -> NAN and inf -> INF.
6359
Mark Hammond5a607a32009-05-06 08:04:54 +00006360- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
6361 in all operations, including splitdrive, split, etc. splitunc() now issues
6362 a PendingDeprecation warning.
6363
Eric Smith63376222009-05-05 14:04:18 +00006364- Issue #5920: For float.__format__, change the behavior with the
6365 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6366 to be like 'g' but with at least one decimal point and with a
6367 default precision of 12. Previously, the behavior the same but with
6368 a default precision of 6. This more closely matches str(), and
6369 reduces surprises when adding alignment flags to the empty
6370 presentation type. This also affects the new complex.__format__ in
6371 the same way.
6372
Martin v. Löwis011e8422009-05-05 04:43:17 +00006373- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
6374
R. David Murrayb18500d2009-05-04 22:59:07 +00006375- Issue #5890: in subclasses of 'property' the __doc__ attribute was
6376 shadowed by classtype's, even if it was None. property now
6377 inserts the __doc__ into the subclass instance __dict__.
6378
Antoine Pitrou244651a2009-05-04 18:56:13 +00006379- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
6380 sequences. Patch by Nick Barnes and Victor Stinner.
6381
Martin v. Löwise0a2b722009-05-10 08:08:56 +00006382- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00006383
Benjamin Petersond2e0c792009-05-01 20:40:59 +00006384- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6385 received a new method, detach(). detach() disconnects the underlying stream
6386 from the buffer or text IO and returns it.
6387
Mark Dickinson33841c32009-05-01 15:37:04 +00006388- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6389 floats with absolute value over 1e50. Also remove length
6390 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6391 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006392
Eric Smith741191f2009-05-06 13:08:15 +00006393- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006394 format(complex(1, 2./3), '.5') now produces a sensible result.
6395
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006396- Issue #5864: Fix empty format code formatting for floats so that it
6397 never gives more than the requested number of significant digits.
6398
Eric Smith6dc46f52009-04-27 20:39:49 +00006399- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6400 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6401
Eric Smithcc32a112009-04-26 21:35:14 +00006402- Issue #5835: Deprecate PyOS_ascii_formatd.
6403
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006404- Issue #4971: Fix titlecase for characters that are their own
6405 titlecase, but not their own uppercase.
6406
Benjamin Peterson193152c2009-04-25 01:08:45 +00006407- Issue #5283: Setting __class__ in __del__ caused a segfault.
6408
Mark Dickinsonad476da2009-04-23 19:14:16 +00006409- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6410 z involves nans, infs or negative zeros.
6411
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006412- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006413
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006414- Issue #1869 (and many duplicates): make round(x, n) correctly
6415 rounded for a float x, by using the decimal <-> binary conversions
6416 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6417 consistently agrees with format(x, '.2f').
6418
Benjamin Petersonae937c02009-04-18 20:54:08 +00006419- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6420 some builtin types.
6421
Eric Smith0923d1d2009-04-16 20:16:10 +00006422- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6423
Eric Smith35e84722009-04-16 20:21:28 +00006424- Issue #5515: str.format() type 'n' combined with commas and leading
6425 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006426
6427- Implement PEP 378, Format Specifier for Thousands Separator, for
6428 floats.
6429
Mark Dickinson3370cce2009-04-17 22:40:53 +00006430- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006431 1e11, not 1e12. This avoids printing 13 significant digits in
6432 situations where only 12 of them are correct. Example problem
6433 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6434 long time.)
6435
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006436- Issue #1580: On most platforms, use a 'short' float repr: for a
6437 finite float x, repr(x) now outputs a string based on the shortest
6438 sequence of decimal digits that rounds to x. Previous behaviour was
6439 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006440 Another minor difference is that the new repr switches to
6441 exponential notation at 1e16 instead of the previous 1e17; this
6442 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006443
6444 There's a new sys attribute sys.float_repr_style, which takes
6445 the value 'short' to indicate that we're using short float repr,
6446 and 'legacy' if the short float repr isn't available for one
6447 reason or another.
6448
6449 The float repr change involves incorporating David Gay's 'perfect
6450 rounding' code into the Python core (it's in Python/dtoa.c). As a
6451 secondary consequence, all string-to-float and float-to-string
6452 conversions (including all float formatting operations) will be
6453 correctly rounded on these platforms.
6454
Georg Brandl5f90d792010-08-01 22:31:05 +00006455 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006456 this change does not apply.
6457
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006458- Issue #5759: float() didn't call __float__ on str subclasses.
6459
Georg Brandlabc38772009-04-12 15:51:51 +00006460- The string.maketrans() function is deprecated; there is a new static method
6461 maketrans() on the bytes and bytearray classes. This removes confusion about
6462 the types string.maketrans() is supposed to work with, and mirrors the
6463 methods available on the str class.
6464
R. David Murraydc6da8a2009-04-09 22:16:43 +00006465- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6466 its clarity and its speed.
6467
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006468- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006469 to avoid compiler warnings.
6470
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006471- Issue #3739: The unicode-internal encoder now reports the number of characters
6472 consumed like any other encoder (instead of the number of bytes).

6486
Raymond Hettingereb816952009-05-29 01:22:18 +00006487- Issue #5150: IDLE's format menu now has an option to strip trailing

Antoine Pitrou3a652b12009-03-23 18:52:06 +00006631- Issue #4688: Add a heuristic so that tuples and dicts containing only
6632 untrackable objects are not tracked by the garbage collector. This can
6633 reduce the size of collections and therefore the garbage collection overhead

Mark Dickinson17e4fdd2009-03-23 18:44:57 +00006636- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
6637 improve its performance. Long divisions and remainder operations
6638 are now between 50% and 150% faster.
6639
Mark Dickinsonbd792642009-03-18 20:06:12 +00006640- Issue #4258: Make it possible to use base 2**30 instead of base
6641 2**15 for the internal representation of integers, for performance
6642 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6643 --enable-big-digits option to configure, which overrides the
6644 default. Add sys.int_info structseq to provide information about
6645 the internal format.

6746 used when using str.format() with str, int, and float arguments.
6747
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006748- Issue #5249: time.strftime returned malformed string when format string
6749 contained non ascii character on windows.

6755 rotating the object pointer by 4 bits to the right.
6756
Mark Dickinson87ec0852009-02-09 17:15:59 +00006757- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6758 it now forces its argument to double before testing for infinity.
6759
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006760- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6761 returns a non-number type.
6762
Benjamin Peterson87618552009-02-08 15:00:52 +00006763- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonc008a172009-02-01 13:59:22 +00006765- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6766 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006767 the type definition cmpfunc. The tp_compare slot has been renamed
6768 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006769
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006770- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006771 were suppressing all exceptions. These include list() and bytearray().
6772
Mark Dickinson1124e712009-01-28 21:25:58 +00006773- Issue #4707: round(x, n) now returns an integer if x is an integer.
6774 Previously it returned a float.
6775
Antoine Pitroub52ec782009-01-25 16:34:23 +00006776- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6777 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6778 evaluation loop is compiled with a new dispatch mechanism which gives
6779 speedups of up to 20%, depending on the system, on various benchmarks.
6780
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006781- Issue #4874: Most builtin decoders now reject unicode input.

6789 optional module state data.
6790
Mark Dickinson8055afd2009-01-17 10:04:45 +00006791- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006792 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006793
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006794- Issue #4935: The overflow checking code in the expandtabs() method common
6795 to str, bytes and bytearray could be optimized away by the compiler, letting
6796 the interpreter segfault instead of raising an error.
6797
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006798- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6799 __next__ method.
6800
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006801- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6802 function no longer attempt to call the __long__ slot to convert an object
6803 to an integer. Only the __int__ and __trunc__ slots are examined.
6804
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006805- Issue #4893: Use NT threading on CE.

6808
Antoine Pitrouab868312009-01-10 15:40:25 +00006809- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6810 common cases are optimized thanks to a dedicated fast path and a moderate
6811 amount of loop unrolling.
6812
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006813- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6814 collecting the oldest generation) so that allocating lots of objects without
6815 destroying them does not show quadratic performance. Based on a proposal by
6816 Martin von Löwis at
6817 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6818
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006819- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006820 having been closed (for instance, a read() call could return some
6821 previously buffered data). Patch by Dmitry Vasiliev.
6822
Antoine Pitrou05608432009-01-09 18:53:14 +00006823- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6824 flag to work properly. Furthermore, when specifying -u, the text stdout
6825 and stderr streams have line-by-line buffering enabled (the default being
6826 to buffer arbitrary chunks of data).
6827
Raymond Hettinger35631532009-01-09 03:58:09 +00006828- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6829 instead of ints (reducing its size from 4 to 8 times thereby reducing
6830 Python's overall memory).
6831
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006832- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6833 an existing .py counterpart, override the co_filename attributes of all
6834 code objects if the original filename is obsolete (which can happen if the
6835 file has been renamed, moved, or if it is accessed through different paths).
6836 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6837
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006838- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6839 one byte. Also fixes the meaning of len() so that it returns the number of
6840 items, rather than the size in bytes.
6841
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006842- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6843
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006844- Issue #4747: When the terminal does not use utf-8, executing a script with
6845 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6846
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006847- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6848 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006849
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006850- Issue #3680: Reference cycles created through a dict, set or deque iterator
6851 did not get collected.
6852
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006853- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6854 where the tp_hash and tp_dict slots are both NULL.
6855
Georg Brandlccc47b62008-12-28 11:44:14 +00006856- Issue #4759: None is now allowed as the first argument of
6857 bytearray.translate(). It was always allowed for bytes.translate().
6858
Skip Montanaro80072cb2008-12-23 03:51:14 +00006859- Added test case to ensure attempts to read from a file opened for writing
6860 fail.
6861
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006862- Issue #3106: Speedup some comparisons (str/str and int/int).

6872
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006873- Issue #2173: When getting device encoding, check that return value of
6874 nl_langinfo is not the empty string. This was causing silent build
6875 failures on OS X.
6876
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006877- Issue #4597: Fixed several opcodes that weren't always propagating
6878 exceptions.
6879
6880- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006881 context manager returns a value that cannot be converted to a bool.
6882
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006883- Issue #4445: Replace "sizeof(PyBytesObject)" with
6884 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6885 bytes instances. On a typical machine this saves 3 bytes of memory
6886 (on average) per allocation of a bytes instance.
6887
Christian Heimesa872de52008-12-05 08:26:55 +00006888- Issue #4533: File read operation was dreadfully slow due to a slowly
6889 growing read buffer. Fixed by using the same growth rate algorithm as
6890 Python 2.x.
6891
Antoine Pitrou5504e892008-12-06 21:27:53 +00006892- Issue #4509: Various issues surrounding resize of bytearray objects to
6893 which there are buffer exports (e.g. memoryview instances).
6894
Georg Brandlf9734072008-12-07 15:30:06 +00006895- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6896 method on file objects with closefd=False. The file descriptor is still
6897 kept open but the file object behaves like a closed file. The ``FileIO``
6898 object also got a new readonly attribute ``closefd``.

6908 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6909 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6910 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00007512- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
7513 regression tests in parallel, shortening the total runtime.
7514
Guilherme Polo2a998fa2009-06-21 17:40:07 +00007515- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
7516 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
7517 the same behaviour as test_ttkguionly (and now also test_tk) which is to
7518 skip the tests if DISPLAY is defined but can't be used.
7519
R. David Murraya21e4ca2009-03-31 23:16:50 +00007520- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00007521 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00007522 from test support, which does the conversion.
7523
Guilherme Polo9de29af2009-01-28 20:40:48 +00007524- Issue #5083: New 'gui' resource for regrtest.
