826 would be turned into a non-blocking SSL socket).
827
Antoine Pitrouec146182010-04-24 21:30:20 +0000828- Issue #5103: SSL handshake would ignore the socket timeout and block

1968 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.

Eric Smith741191f2009-05-06 13:08:15 +00001970- Issue #3382: float.__format__, complex.__format__, and %-formatting

1977
Eric Smith63376222009-05-05 14:04:18 +00001978- Issue #5920: For float.__format__, change the behavior with the
1979 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1980 to be like 'g' but with at least one decimal point and with a
1981 default precision of 12. Previously, the behavior the same but with
1982 a default precision of 6. This more closely matches str(), and
1983 reduces surprises when adding alignment flags to the empty
1984 presentation type. This also affects the new complex.__format__ in
1985 the same way.
1986
Martin v. Löwis011e8422009-05-05 04:43:17 +00001987- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001998- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1999 received a new method, detach(). detach() disconnects the underlying stream
2000 from the buffer or text IO and returns it.
2001
Mark Dickinson33841c32009-05-01 15:37:04 +00002002- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2003 floats with absolute value over 1e50. Also remove length
2004 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Mark Dickinsone6a076d2009-04-18 11:48:33 +00002028- Issue #1869 (and many duplicates): make round(x, n) correctly
2029 rounded for a float x, by using the decimal <-> binary conversions
2030 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2031 consistently agrees with format(x, '.2f').
2032
Benjamin Petersonae937c02009-04-18 20:54:08 +00002033- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2034 some builtin types.
2035
Eric Smith0923d1d2009-04-16 20:16:10 +00002036- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2037
Eric Smith35e84722009-04-16 20:21:28 +00002038- Issue #5515: str.format() type 'n' combined with commas and leading
2039 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002040
2041- Implement PEP 378, Format Specifier for Thousands Separator, for
2042 floats.
2043
Mark Dickinson3370cce2009-04-17 22:40:53 +00002044- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002045 1e11, not 1e12. This avoids printing 13 significant digits in
2046 situations where only 12 of them are correct. Example problem
2047 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2048 long time.)
2049
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002050- Issue #1580: On most platforms, use a 'short' float repr: for a
2051 finite float x, repr(x) now outputs a string based on the shortest
2052 sequence of decimal digits that rounds to x. Previous behaviour was
2053 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002054 Another minor difference is that the new repr switches to
2055 exponential notation at 1e16 instead of the previous 1e17; this
2056 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002057
2058 There's a new sys attribute sys.float_repr_style, which takes
2059 the value 'short' to indicate that we're using short float repr,
2060 and 'legacy' if the short float repr isn't available for one
2061 reason or another.
2062
2063 The float repr change involves incorporating David Gay's 'perfect
2064 rounding' code into the Python core (it's in Python/dtoa.c). As a
2065 secondary consequence, all string-to-float and float-to-string
2066 conversions (including all float formatting operations) will be
2067 correctly rounded on these platforms.
2068
Georg Brandl442d3b32010-08-01 22:33:12 +00002069 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002070 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002072- Issue #5759: float() didn't call __float__ on str subclasses.
2073
Georg Brandlabc38772009-04-12 15:51:51 +00002074- The string.maketrans() function is deprecated; there is a new static method
2075 maketrans() on the bytes and bytearray classes. This removes confusion about
2076 the types string.maketrans() is supposed to work with, and mirrors the
2077 methods available on the str class.
2078
R. David Murraydc6da8a2009-04-09 22:16:43 +00002079- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

2244 untrackable objects are not tracked by the garbage collector. This can
2245 reduce the size of collections and therefore the garbage collection overhead
2246 on long-running programs, depending on their particular use of datatypes.

2339 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00002340 struct.error instead of returning b'\xff\xff\xff\xff'. The
2341 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2342 have been removed from the struct module.

2361 contained non ascii character on windows.
2362
Benjamin Petersonf5b52242009-03-02 23:31:26 +00002363- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
2364 source has already been decoded into str.
2365
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002366- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2367 rotating the object pointer by 4 bits to the right.
2368
Mark Dickinson87ec0852009-02-09 17:15:59 +00002369- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2370 it now forces its argument to double before testing for infinity.
2371
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002372- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2373 returns a non-number type.
2374
Benjamin Peterson87618552009-02-08 15:00:52 +00002375- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002381
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002382- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002383 were suppressing all exceptions. These include list() and bytearray().
2384
Mark Dickinson1124e712009-01-28 21:25:58 +00002385- Issue #4707: round(x, n) now returns an integer if x is an integer.
2386 Previously it returned a float.
2387
Antoine Pitroub52ec782009-01-25 16:34:23 +00002388- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2389 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2390 evaluation loop is compiled with a new dispatch mechanism which gives
2391 speedups of up to 20%, depending on the system, on various benchmarks.
2392
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002393- Issue #4874: Most builtin decoders now reject unicode input.

2399
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002400- Issue #4838: When a module is deallocated, free the memory backing the
2401 optional module state data.
2402
Mark Dickinson8055afd2009-01-17 10:04:45 +00002403- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2404 type to (void *).
2405
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002406- Issue #4935: The overflow checking code in the expandtabs() method common
2407 to str, bytes and bytearray could be optimized away by the compiler, letting
2408 the interpreter segfault instead of raising an error.
2409
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002410- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2411 __next__ method.
2412
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002413- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2414 function no longer attempt to call the __long__ slot to convert an object
2415 to an integer. Only the __int__ and __trunc__ slots are examined.
2416
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002417- Issue #4893: Use NT threading on CE.
2418
Martin v. Löwisec59d042009-01-12 07:59:10 +00002419- Issue #4915: Port sysmodule to Windows CE.
2420
Antoine Pitrouab868312009-01-10 15:40:25 +00002421- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2422 common cases are optimized thanks to a dedicated fast path and a moderate
2423 amount of loop unrolling.
2424
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002425- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2426 collecting the oldest generation) so that allocating lots of objects without
2427 destroying them does not show quadratic performance. Based on a proposal by
2428 Martin von Löwis at
2429 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2430
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002431- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002432 having been closed (for instance, a read() call could return some
2433 previously buffered data). Patch by Dmitry Vasiliev.
2434
Antoine Pitrou05608432009-01-09 18:53:14 +00002435- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2436 flag to work properly. Furthermore, when specifying -u, the text stdout
2437 and stderr streams have line-by-line buffering enabled (the default being
2438 to buffer arbitrary chunks of data).
2439
Raymond Hettinger35631532009-01-09 03:58:09 +00002440- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2441 instead of ints (reducing its size from 4 to 8 times thereby reducing
2442 Python's overall memory).
2443
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002444- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2445 an existing .py counterpart, override the co_filename attributes of all
2446 code objects if the original filename is obsolete (which can happen if the
2447 file has been renamed, moved, or if it is accessed through different paths).
2448 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2449
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002450- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2451 one byte. Also fixes the meaning of len() so that it returns the number of
2452 items, rather than the size in bytes.
2453
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002454- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2455
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002456- Issue #4747: When the terminal does not use utf-8, executing a script with
2457 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2458
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002459- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002460 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002461
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002462- Issue #3680: Reference cycles created through a dict, set or deque iterator
2463 did not get collected.
2464
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002465- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2466 where the tp_hash and tp_dict slots are both NULL.
2467
Georg Brandlccc47b62008-12-28 11:44:14 +00002468- Issue #4759: None is now allowed as the first argument of
2469 bytearray.translate(). It was always allowed for bytes.translate().
2470
Skip Montanaro80072cb2008-12-23 03:51:14 +00002471- Added test case to ensure attempts to read from a file opened for writing
2472 fail.
2473
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002474- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00002476- Issue #2183: Simplify and optimize bytecode for list, dict and set
2477 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2478
Antoine Pitrou621601a2008-12-17 23:18:19 +00002479- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2480 print elapsed times, not only when some objects are uncollectable /
2481 unreachable. Original patch by Neil Schemenauer.
2482
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002483- Issue #3439: Add a bit_length method to int.
2484
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002485- Issue #2173: When getting device encoding, check that return value of
2486 nl_langinfo is not the empty string. This was causing silent build
2487 failures on OS X.
2488
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002489- Issue #4597: Fixed several opcodes that weren't always propagating
2490 exceptions.
2491
2492- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002493 context manager returns a value that cannot be converted to a bool.
2494
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002495- Issue #4445: Replace "sizeof(PyBytesObject)" with
2496 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2497 bytes instances. On a typical machine this saves 3 bytes of memory
2498 (on average) per allocation of a bytes instance.
2499
Christian Heimesa872de52008-12-05 08:26:55 +00002500- Issue #4533: File read operation was dreadfully slow due to a slowly
2501 growing read buffer. Fixed by using the same growth rate algorithm as
2502 Python 2.x.
2503
Antoine Pitrou5504e892008-12-06 21:27:53 +00002504- Issue #4509: Various issues surrounding resize of bytearray objects to
2505 which there are buffer exports (e.g. memoryview instances).
2506
Georg Brandlf9734072008-12-07 15:30:06 +00002507- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2508 method on file objects with closefd=False. The file descriptor is still
2509 kept open but the file object behaves like a closed file. The ``FileIO``
2510 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002511
Antoine Pitroubc420402008-12-07 20:14:49 +00002512- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2513 larger than 1.

2518
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002519- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2520 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2521 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2522 of using the replace error handler in PyUnicode_DecodeUTF8().
