167 Decimal operation raises multiple signals and more than one of those
168 signals is trapped, the specification determines the order in which
169 the signals should be handled. In many cases this order wasn't
170 being followed, leading to the wrong Python exception being raised.

201 witnessed in test_httpservers.
202
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000203- Issue #8524: When creating an SSL socket, the timeout value of the
204 original socket wasn't retained (instead, a socket with a positive timeout
205 would be turned into a non-blocking SSL socket).
206
Antoine Pitrouec146182010-04-24 21:30:20 +0000207- Issue #5103: SSL handshake would ignore the socket timeout and block
208 indefinitely if the other end didn't respond.

245 encoding unicode as utf8 to support lone surrogates and stay compatible with
246 Python 2.x and 3.0
247

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001206
1207Core and Builtins
1208-----------------
1209
Mark Dickinson865e01a2009-05-07 16:37:01 +00001210- Issue #5914: Add new C API function PyOS_string_to_double, and
1211 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1212
Eric Smith741191f2009-05-06 13:08:15 +00001213- Issue #3382: float.__format__, complex.__format__, and %-formatting
1214 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1215 affects nan -> NAN and inf -> INF.
1216
Mark Hammond5a607a32009-05-06 08:04:54 +00001217- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1218 in all operations, including splitdrive, split, etc. splitunc() now issues
1219 a PendingDeprecation warning.
1220
Eric Smith63376222009-05-05 14:04:18 +00001221- Issue #5920: For float.__format__, change the behavior with the
1222 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1223 to be like 'g' but with at least one decimal point and with a
1224 default precision of 12. Previously, the behavior the same but with
1225 a default precision of 6. This more closely matches str(), and
1226 reduces surprises when adding alignment flags to the empty
1227 presentation type. This also affects the new complex.__format__ in
1228 the same way.
1229
Martin v. Löwis011e8422009-05-05 04:43:17 +00001230- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1231
R. David Murrayb18500d2009-05-04 22:59:07 +00001232- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1233 shadowed by classtype's, even if it was None. property now
1234 inserts the __doc__ into the subclass instance __dict__.
1235
Antoine Pitrou244651a2009-05-04 18:56:13 +00001236- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1237 sequences. Patch by Nick Barnes and Victor Stinner.
1238
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001239- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001240
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001241- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1242 received a new method, detach(). detach() disconnects the underlying stream
1243 from the buffer or text IO and returns it.
1244
Mark Dickinson33841c32009-05-01 15:37:04 +00001245- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1246 floats with absolute value over 1e50. Also remove length
1247 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1248 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001249
Eric Smith741191f2009-05-06 13:08:15 +00001250- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001251 format(complex(1, 2./3), '.5') now produces a sensible result.
1252
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001253- Issue #5864: Fix empty format code formatting for floats so that it
1254 never gives more than the requested number of significant digits.
1255
Eric Smith6dc46f52009-04-27 20:39:49 +00001256- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1257 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1258
Eric Smithcc32a112009-04-26 21:35:14 +00001259- Issue #5835: Deprecate PyOS_ascii_formatd.
1260
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001261- Issue #4971: Fix titlecase for characters that are their own
1262 titlecase, but not their own uppercase.
1263
Benjamin Peterson193152c2009-04-25 01:08:45 +00001264- Issue #5283: Setting __class__ in __del__ caused a segfault.
1265
Mark Dickinsonad476da2009-04-23 19:14:16 +00001266- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1267 z involves nans, infs or negative zeros.
1268
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001269- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001270
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001271- Issue #1869 (and many duplicates): make round(x, n) correctly
1272 rounded for a float x, by using the decimal <-> binary conversions
1273 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1274 consistently agrees with format(x, '.2f').
1275
Benjamin Petersonae937c02009-04-18 20:54:08 +00001276- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1277 some builtin types.
1278
Eric Smith0923d1d2009-04-16 20:16:10 +00001279- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1280
Eric Smith35e84722009-04-16 20:21:28 +00001281- Issue #5515: str.format() type 'n' combined with commas and leading
1282 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001283
1284- Implement PEP 378, Format Specifier for Thousands Separator, for
1285 floats.
1286
Mark Dickinson3370cce2009-04-17 22:40:53 +00001287- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001288 1e11, not 1e12. This avoids printing 13 significant digits in
1289 situations where only 12 of them are correct. Example problem
1290 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1291 long time.)
1292
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001293- Issue #1580: On most platforms, use a 'short' float repr: for a
1294 finite float x, repr(x) now outputs a string based on the shortest
1295 sequence of decimal digits that rounds to x. Previous behaviour was
1296 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001297 Another minor difference is that the new repr switches to
1298 exponential notation at 1e16 instead of the previous 1e17; this
1299 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001300
1301 There's a new sys attribute sys.float_repr_style, which takes
1302 the value 'short' to indicate that we're using short float repr,
1303 and 'legacy' if the short float repr isn't available for one
1304 reason or another.
1305
1306 The float repr change involves incorporating David Gay's 'perfect
1307 rounding' code into the Python core (it's in Python/dtoa.c). As a
1308 secondary consequence, all string-to-float and float-to-string
1309 conversions (including all float formatting operations) will be
1310 correctly rounded on these platforms.
1311
1312 See issue 1580 discussions for details of platforms for which
1313 this change does not apply.
1314
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001315- Issue #5759: float() didn't call __float__ on str subclasses.
1316
Georg Brandlabc38772009-04-12 15:51:51 +00001317- The string.maketrans() function is deprecated; there is a new static method
1318 maketrans() on the bytes and bytearray classes. This removes confusion about
1319 the types string.maketrans() is supposed to work with, and mirrors the
1320 methods available on the str class.
1321
R. David Murraydc6da8a2009-04-09 22:16:43 +00001322- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1323 its clarity and its speed.
1324
Matthias Klose091c7b12009-04-07 13:24:27 +00001325- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1326 to avoid compiler warnings.
1327
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001328- Issue #3739: The unicode-internal encoder now reports the number of characters
1329 consumed like any other encoder (instead of the number of bytes).

1473
Georg Brandlab6f2f62009-03-31 04:16:10 +00001474- Fix a segfault when running test_exceptions with coverage, caused by
1475 insufficient checks in accessors of Exception.__context__.
1476
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001477- Issue #5604: non-ASCII characters in module name passed to
1478 imp.find_module() were converted to UTF-8 while the path is
1479 converted to the default filesystem encoding, causing nonsense.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001483- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1484 the end sys.path, for compatibility with the system install of Python.
1485
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001486- Issue #4688: Add a heuristic so that tuples and dicts containing only
1487 untrackable objects are not tracked by the garbage collector. This can
1488 reduce the size of collections and therefore the garbage collection overhead
1489 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001491- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
1492 improve its performance. Long divisions and remainder operations
1493 are now between 50% and 150% faster.
1494
Mark Dickinsonbd792642009-03-18 20:06:12 +00001495- Issue #4258: Make it possible to use base 2**30 instead of base
1496 2**15 for the internal representation of integers, for performance
1497 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1498 --enable-big-digits option to configure, which overrides the
1499 default. Add sys.int_info structseq to provide information about
1500 the internal format.
1501
Mark Dickinson081dfee2009-03-18 14:47:41 +00001502- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1503 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1504 and sizeof(Py_UNICODE) == 2.
1505
Eric Smith8ec90442009-03-14 12:29:34 +00001506- Issue #5237: Allow auto-numbered fields in str.format(). For

1508
Antoine Pitrou652e7072009-03-13 19:25:20 +00001509- Issue #5392: when a very low recursion limit was set, the interpreter would
1510 abort with a fatal error after the recursion limit was hit twice.
1511
Matthias Klose042f1332009-04-04 14:32:42 +00001512- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

Mark Dickinson87ec0852009-02-09 17:15:59 +00001612- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1613 it now forces its argument to double before testing for infinity.
1614
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001615- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1616 returns a non-number type.

1623 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001624
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001625- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001626 were suppressing all exceptions. These include list() and bytearray().
1627
Mark Dickinson1124e712009-01-28 21:25:58 +00001628- Issue #4707: round(x, n) now returns an integer if x is an integer.
1629 Previously it returned a float.
1630
Antoine Pitroub52ec782009-01-25 16:34:23 +00001631- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1632 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1633 evaluation loop is compiled with a new dispatch mechanism which gives
1634 speedups of up to 20%, depending on the system, on various benchmarks.
1635
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001636- Issue #4874: Most builtin decoders now reject unicode input.

1642
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001643- Issue #4838: When a module is deallocated, free the memory backing the
1644 optional module state data.
1645
Mark Dickinson8055afd2009-01-17 10:04:45 +00001646- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1647 type to (void *).
1648
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001649- Issue #4935: The overflow checking code in the expandtabs() method common
1650 to str, bytes and bytearray could be optimized away by the compiler, letting
1651 the interpreter segfault instead of raising an error.
1652
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001653- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1654 __next__ method.
1655
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001656- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1663
Antoine Pitrouab868312009-01-10 15:40:25 +00001664- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1665 common cases are optimized thanks to a dedicated fast path and a moderate
1666 amount of loop unrolling.
1667
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001668- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1669 collecting the oldest generation) so that allocating lots of objects without
1670 destroying them does not show quadratic performance. Based on a proposal by
1671 Martin von Löwis at
1672 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1673
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001674- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001675 having been closed (for instance, a read() call could return some
1676 previously buffered data). Patch by Dmitry Vasiliev.
1677
Antoine Pitrou05608432009-01-09 18:53:14 +00001678- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1679 flag to work properly. Furthermore, when specifying -u, the text stdout
1680 and stderr streams have line-by-line buffering enabled (the default being
1681 to buffer arbitrary chunks of data).
1682
Raymond Hettinger35631532009-01-09 03:58:09 +00001683- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1684 instead of ints (reducing its size from 4 to 8 times thereby reducing
1685 Python's overall memory).
1686
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001687- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1688 an existing .py counterpart, override the co_filename attributes of all
1689 code objects if the original filename is obsolete (which can happen if the
1690 file has been renamed, moved, or if it is accessed through different paths).
1691 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1692
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001693- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1694 one byte. Also fixes the meaning of len() so that it returns the number of
1695 items, rather than the size in bytes.
1696
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001697- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1698
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001699- Issue #4747: When the terminal does not use utf-8, executing a script with
1700 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1701
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001702- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001703 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001704
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001705- Issue #3680: Reference cycles created through a dict, set or deque iterator
1706 did not get collected.
1707
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001708- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1709 where the tp_hash and tp_dict slots are both NULL.
1710
Georg Brandlccc47b62008-12-28 11:44:14 +00001711- Issue #4759: None is now allowed as the first argument of
1712 bytearray.translate(). It was always allowed for bytes.translate().
1713
Skip Montanaro80072cb2008-12-23 03:51:14 +00001714- Added test case to ensure attempts to read from a file opened for writing
1715 fail.
1716
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001717- Issue #3106: Speedup some comparisons (str/str and int/int).

1720 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1721
Antoine Pitrou621601a2008-12-17 23:18:19 +00001722- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1723 print elapsed times, not only when some objects are uncollectable /
1724 unreachable. Original patch by Neil Schemenauer.
1725
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001726- Issue #3439: Add a bit_length method to int.
1727
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001728- Issue #2173: When getting device encoding, check that return value of
1729 nl_langinfo is not the empty string. This was causing silent build
1730 failures on OS X.
1731
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001732- Issue #4597: Fixed several opcodes that weren't always propagating
1733 exceptions.
1734
1735- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001736 context manager returns a value that cannot be converted to a bool.
1737
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001738- Issue #4445: Replace "sizeof(PyBytesObject)" with
1739 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1740 bytes instances. On a typical machine this saves 3 bytes of memory
1741 (on average) per allocation of a bytes instance.
1742
Christian Heimesa872de52008-12-05 08:26:55 +00001743- Issue #4533: File read operation was dreadfully slow due to a slowly
1744 growing read buffer. Fixed by using the same growth rate algorithm as
1745 Python 2.x.
1746
Antoine Pitrou5504e892008-12-06 21:27:53 +00001747- Issue #4509: Various issues surrounding resize of bytearray objects to
1748 which there are buffer exports (e.g. memoryview instances).
1749
Georg Brandlf9734072008-12-07 15:30:06 +00001750- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1751 method on file objects with closefd=False. The file descriptor is still
1752 kept open but the file object behaves like a closed file. The ``FileIO``
1753 object also got a new readonly attribute ``closefd``.
