Ezio Melotti25bc0192010-07-03 05:18:50 +0000334- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

338 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
339 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
340 Previous versions returned a single u'\ufffd'.

819 would be turned into a non-blocking SSL socket).
820
Antoine Pitrouec146182010-04-24 21:30:20 +0000821- Issue #5103: SSL handshake would ignore the socket timeout and block

1961 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.

1969 a PendingDeprecation warning.
1970
Eric Smith63376222009-05-05 14:04:18 +00001971- Issue #5920: For float.__format__, change the behavior with the
1972 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1973 to be like 'g' but with at least one decimal point and with a
1974 default precision of 12. Previously, the behavior the same but with
1975 a default precision of 6. This more closely matches str(), and
1976 reduces surprises when adding alignment flags to the empty
1977 presentation type. This also affects the new complex.__format__ in
1978 the same way.
1979
Martin v. Löwis011e8422009-05-05 04:43:17 +00001980- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1983 shadowed by classtype's, even if it was None. property now
1984 inserts the __doc__ into the subclass instance __dict__.
1985
Antoine Pitrou244651a2009-05-04 18:56:13 +00001986- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001991- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1992 received a new method, detach(). detach() disconnects the underlying stream
1993 from the buffer or text IO and returns it.
1994
Mark Dickinson33841c32009-05-01 15:37:04 +00001995- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1996 floats with absolute value over 1e50. Also remove length
1997 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1998 12.34 no longer raise an exception.

2004 never gives more than the requested number of significant digits.
2005
Eric Smith6dc46f52009-04-27 20:39:49 +00002006- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +00002016- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2017 z involves nans, infs or negative zeros.
2018
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002019- Issue #3166: Make int -> float conversions correctly rounded.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00002021- Issue #1869 (and many duplicates): make round(x, n) correctly
2022 rounded for a float x, by using the decimal <-> binary conversions
2023 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2024 consistently agrees with format(x, '.2f').
2025
Benjamin Petersonae937c02009-04-18 20:54:08 +00002026- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2027 some builtin types.

Eric Smith0923d1d2009-04-16 20:16:10 +00002029- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2030
Eric Smith35e84722009-04-16 20:21:28 +00002031- Issue #5515: str.format() type 'n' combined with commas and leading
2032 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002033
2034- Implement PEP 378, Format Specifier for Thousands Separator, for
2035 floats.
2036
Mark Dickinson3370cce2009-04-17 22:40:53 +00002037- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002038 1e11, not 1e12. This avoids printing 13 significant digits in
2039 situations where only 12 of them are correct. Example problem
2040 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2041 long time.)
2042
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002043- Issue #1580: On most platforms, use a 'short' float repr: for a
2044 finite float x, repr(x) now outputs a string based on the shortest
2045 sequence of decimal digits that rounds to x. Previous behaviour was
2046 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002047 Another minor difference is that the new repr switches to
2048 exponential notation at 1e16 instead of the previous 1e17; this
2049 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002050
2051 There's a new sys attribute sys.float_repr_style, which takes
2052 the value 'short' to indicate that we're using short float repr,
2053 and 'legacy' if the short float repr isn't available for one
2054 reason or another.
2055
2056 The float repr change involves incorporating David Gay's 'perfect
2057 rounding' code into the Python core (it's in Python/dtoa.c). As a
2058 secondary consequence, all string-to-float and float-to-string
2059 conversions (including all float formatting operations) will be
2060 correctly rounded on these platforms.
2061
Georg Brandl442d3b32010-08-01 22:33:12 +00002062 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002063 this change does not apply.
2064
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002065- Issue #5759: float() didn't call __float__ on str subclasses.
2066
Georg Brandlabc38772009-04-12 15:51:51 +00002067- The string.maketrans() function is deprecated; there is a new static method
2068 maketrans() on the bytes and bytearray classes. This removes confusion about
2069 the types string.maketrans() is supposed to work with, and mirrors the
2070 methods available on the str class.
2071
R. David Murraydc6da8a2009-04-09 22:16:43 +00002072- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2073 its clarity and its speed.
2074
Matthias Klose091c7b12009-04-07 13:24:27 +00002075- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2076 to avoid compiler warnings.
2077
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002078- Issue #3739: The unicode-internal encoder now reports the number of characters
2079 consumed like any other encoder (instead of the number of bytes).

2235
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002236- Issue #4688: Add a heuristic so that tuples and dicts containing only
2237 untrackable objects are not tracked by the garbage collector. This can
2238 reduce the size of collections and therefore the garbage collection overhead
2239 on long-running programs, depending on their particular use of datatypes.

Mark Dickinsonae681df2009-03-21 10:26:31 +00002331- Issue #5463: In struct module, remove deprecated overflow wrapping
2332 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00002333 struct.error instead of returning b'\xff\xff\xff\xff'. The
2334 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2335 have been removed from the struct module.

2351 used when using str.format() with str, int, and float arguments.
2352
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00002353- Issue #5249: time.strftime returned malformed string when format string
2354 contained non ascii character on windows.
2355
Benjamin Petersonf5b52242009-03-02 23:31:26 +00002356- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
2357 source has already been decoded into str.
2358
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002359- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2360 rotating the object pointer by 4 bits to the right.
2361
Mark Dickinson87ec0852009-02-09 17:15:59 +00002362- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2363 it now forces its argument to double before testing for infinity.
2364
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002365- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

2373 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002374
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002375- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002376 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00002378- Issue #4707: round(x, n) now returns an integer if x is an integer.
2379 Previously it returned a float.
2380
Antoine Pitroub52ec782009-01-25 16:34:23 +00002381- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2382 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2383 evaluation loop is compiled with a new dispatch mechanism which gives
2384 speedups of up to 20%, depending on the system, on various benchmarks.
2385
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002386- Issue #4874: Most builtin decoders now reject unicode input.

2392
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002393- Issue #4838: When a module is deallocated, free the memory backing the
2394 optional module state data.
2395
Mark Dickinson8055afd2009-01-17 10:04:45 +00002396- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2397 type to (void *).
2398
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002399- Issue #4935: The overflow checking code in the expandtabs() method common
2400 to str, bytes and bytearray could be optimized away by the compiler, letting
2401 the interpreter segfault instead of raising an error.
2402
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002403- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2404 __next__ method.
2405
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002406- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2407 function no longer attempt to call the __long__ slot to convert an object
2408 to an integer. Only the __int__ and __trunc__ slots are examined.
2409
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002410- Issue #4893: Use NT threading on CE.
2411
Martin v. Löwisec59d042009-01-12 07:59:10 +00002412- Issue #4915: Port sysmodule to Windows CE.
2413
Antoine Pitrouab868312009-01-10 15:40:25 +00002414- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2415 common cases are optimized thanks to a dedicated fast path and a moderate
2416 amount of loop unrolling.
2417
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002418- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2419 collecting the oldest generation) so that allocating lots of objects without
2420 destroying them does not show quadratic performance. Based on a proposal by
2421 Martin von Löwis at
2422 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2423
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002424- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002425 having been closed (for instance, a read() call could return some
2426 previously buffered data). Patch by Dmitry Vasiliev.
2427
Antoine Pitrou05608432009-01-09 18:53:14 +00002428- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2429 flag to work properly. Furthermore, when specifying -u, the text stdout
2430 and stderr streams have line-by-line buffering enabled (the default being
2431 to buffer arbitrary chunks of data).
2432
Raymond Hettinger35631532009-01-09 03:58:09 +00002433- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2434 instead of ints (reducing its size from 4 to 8 times thereby reducing
2435 Python's overall memory).
2436
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002437- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2438 an existing .py counterpart, override the co_filename attributes of all
2439 code objects if the original filename is obsolete (which can happen if the
2440 file has been renamed, moved, or if it is accessed through different paths).
2441 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2442
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002443- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2444 one byte. Also fixes the meaning of len() so that it returns the number of
2445 items, rather than the size in bytes.
2446
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002447- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2448
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002449- Issue #4747: When the terminal does not use utf-8, executing a script with
2450 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2451
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002452- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002453 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002454
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002455- Issue #3680: Reference cycles created through a dict, set or deque iterator
2456 did not get collected.
2457
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002458- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2459 where the tp_hash and tp_dict slots are both NULL.
2460
Georg Brandlccc47b62008-12-28 11:44:14 +00002461- Issue #4759: None is now allowed as the first argument of
2462 bytearray.translate(). It was always allowed for bytes.translate().
2463
Skip Montanaro80072cb2008-12-23 03:51:14 +00002464- Added test case to ensure attempts to read from a file opened for writing
2465 fail.
2466
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002467- Issue #3106: Speedup some comparisons (str/str and int/int).
2468
Antoine Pitrouf289ae62008-12-18 11:06:25 +00002469- Issue #2183: Simplify and optimize bytecode for list, dict and set
2470 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2471
Antoine Pitrou621601a2008-12-17 23:18:19 +00002472- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2473 print elapsed times, not only when some objects are uncollectable /
2474 unreachable. Original patch by Neil Schemenauer.
2475
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002476- Issue #3439: Add a bit_length method to int.
2477
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002478- Issue #2173: When getting device encoding, check that return value of
2479 nl_langinfo is not the empty string. This was causing silent build
2480 failures on OS X.
2481
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002482- Issue #4597: Fixed several opcodes that weren't always propagating
2483 exceptions.
2484
2485- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002486 context manager returns a value that cannot be converted to a bool.
2487
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002488- Issue #4445: Replace "sizeof(PyBytesObject)" with
2489 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2490 bytes instances. On a typical machine this saves 3 bytes of memory
2491 (on average) per allocation of a bytes instance.
2492
Christian Heimesa872de52008-12-05 08:26:55 +00002493- Issue #4533: File read operation was dreadfully slow due to a slowly
2494 growing read buffer. Fixed by using the same growth rate algorithm as
2495 Python 2.x.
2496
Antoine Pitrou5504e892008-12-06 21:27:53 +00002497- Issue #4509: Various issues surrounding resize of bytearray objects to
2498 which there are buffer exports (e.g. memoryview instances).
2499
Georg Brandlf9734072008-12-07 15:30:06 +00002500- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2501 method on file objects with closefd=False. The file descriptor is still
2502 kept open but the file object behaves like a closed file. The ``FileIO``
2503 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002504
Antoine Pitroubc420402008-12-07 20:14:49 +00002505- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2506 larger than 1.
2507

2511
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002512- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2513 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2514 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2515 of using the replace error handler in PyUnicode_DecodeUTF8().
