132 Decimal operation raises multiple signals and more than one of those

166 witnessed in test_httpservers.
167
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000168- Issue #8524: When creating an SSL socket, the timeout value of the
169 original socket wasn't retained (instead, a socket with a positive timeout
170 would be turned into a non-blocking SSL socket).
171
Antoine Pitrouec146182010-04-24 21:30:20 +0000172- Issue #5103: SSL handshake would ignore the socket timeout and block

214
Antoine Pitrou9004edd2010-03-23 00:28:26 +0000215- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

224 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
225 reads and writes are always retried by OpenSSL itself.

Eric Smith63376222009-05-05 14:04:18 +00001173- Issue #5920: For float.__format__, change the behavior with the
1174 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1175 to be like 'g' but with at least one decimal point and with a
1176 default precision of 12. Previously, the behavior the same but with
1177 a default precision of 6. This more closely matches str(), and
1178 reduces surprises when adding alignment flags to the empty
1179 presentation type. This also affects the new complex.__format__ in
1180 the same way.
1181
Martin v. Löwis011e8422009-05-05 04:43:17 +00001182- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1183
R. David Murrayb18500d2009-05-04 22:59:07 +00001184- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1185 shadowed by classtype's, even if it was None. property now
1186 inserts the __doc__ into the subclass instance __dict__.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001193- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1194 received a new method, detach(). detach() disconnects the underlying stream
1195 from the buffer or text IO and returns it.
1196
Mark Dickinson33841c32009-05-01 15:37:04 +00001197- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1198 floats with absolute value over 1e50. Also remove length
1199 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1200 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001201
Eric Smith741191f2009-05-06 13:08:15 +00001202- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001203 format(complex(1, 2./3), '.5') now produces a sensible result.
1204
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001205- Issue #5864: Fix empty format code formatting for floats so that it
1206 never gives more than the requested number of significant digits.
1207
Eric Smith6dc46f52009-04-27 20:39:49 +00001208- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1214 titlecase, but not their own uppercase.
1215
Benjamin Peterson193152c2009-04-25 01:08:45 +00001216- Issue #5283: Setting __class__ in __del__ caused a segfault.
1217
Mark Dickinsonad476da2009-04-23 19:14:16 +00001218- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1219 z involves nans, infs or negative zeros.
1220
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001221- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001222
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001223- Issue #1869 (and many duplicates): make round(x, n) correctly
1224 rounded for a float x, by using the decimal <-> binary conversions
1225 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1226 consistently agrees with format(x, '.2f').
1227
Benjamin Petersonae937c02009-04-18 20:54:08 +00001228- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1229 some builtin types.
1230
Eric Smith0923d1d2009-04-16 20:16:10 +00001231- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1232
Eric Smith35e84722009-04-16 20:21:28 +00001233- Issue #5515: str.format() type 'n' combined with commas and leading
1234 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001235
1236- Implement PEP 378, Format Specifier for Thousands Separator, for
1237 floats.
1238
Mark Dickinson3370cce2009-04-17 22:40:53 +00001239- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001240 1e11, not 1e12. This avoids printing 13 significant digits in
1241 situations where only 12 of them are correct. Example problem
1242 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1243 long time.)
1244
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001245- Issue #1580: On most platforms, use a 'short' float repr: for a
1246 finite float x, repr(x) now outputs a string based on the shortest
1247 sequence of decimal digits that rounds to x. Previous behaviour was
1248 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001249 Another minor difference is that the new repr switches to
1250 exponential notation at 1e16 instead of the previous 1e17; this
1251 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001252
1253 There's a new sys attribute sys.float_repr_style, which takes
1254 the value 'short' to indicate that we're using short float repr,
1255 and 'legacy' if the short float repr isn't available for one
1256 reason or another.
1257
1258 The float repr change involves incorporating David Gay's 'perfect
1259 rounding' code into the Python core (it's in Python/dtoa.c). As a
1260 secondary consequence, all string-to-float and float-to-string
1261 conversions (including all float formatting operations) will be
1262 correctly rounded on these platforms.
1263
1264 See issue 1580 discussions for details of platforms for which
1265 this change does not apply.
1266
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001267- Issue #5759: float() didn't call __float__ on str subclasses.
1268
Georg Brandlabc38772009-04-12 15:51:51 +00001269- The string.maketrans() function is deprecated; there is a new static method
1270 maketrans() on the bytes and bytearray classes. This removes confusion about
1271 the types string.maketrans() is supposed to work with, and mirrors the
1272 methods available on the str class.
1273
R. David Murraydc6da8a2009-04-09 22:16:43 +00001274- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1275 its clarity and its speed.
1276
Matthias Klose091c7b12009-04-07 13:24:27 +00001277- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1278 to avoid compiler warnings.
1279
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001280- Issue #3739: The unicode-internal encoder now reports the number of characters
1281 consumed like any other encoder (instead of the number of bytes).

1437
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001438- Issue #4688: Add a heuristic so that tuples and dicts containing only
1439 untrackable objects are not tracked by the garbage collector. This can
1440 reduce the size of collections and therefore the garbage collection overhead
1441 on long-running programs, depending on their particular use of datatypes.

1562 rotating the object pointer by 4 bits to the right.
1563
Mark Dickinson87ec0852009-02-09 17:15:59 +00001564- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1565 it now forces its argument to double before testing for infinity.
1566
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001567- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

1575 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001576
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001577- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001578 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00001580- Issue #4707: round(x, n) now returns an integer if x is an integer.
1581 Previously it returned a float.
1582
Antoine Pitroub52ec782009-01-25 16:34:23 +00001583- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1584 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1585 evaluation loop is compiled with a new dispatch mechanism which gives
1586 speedups of up to 20%, depending on the system, on various benchmarks.
1587
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001588- Issue #4874: Most builtin decoders now reject unicode input.

1594
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001595- Issue #4838: When a module is deallocated, free the memory backing the
1596 optional module state data.
1597
Mark Dickinson8055afd2009-01-17 10:04:45 +00001598- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1599 type to (void *).
1600
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001601- Issue #4935: The overflow checking code in the expandtabs() method common
1602 to str, bytes and bytearray could be optimized away by the compiler, letting
1603 the interpreter segfault instead of raising an error.
1604
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001605- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1606 __next__ method.
1607
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001608- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1609 function no longer attempt to call the __long__ slot to convert an object
1610 to an integer. Only the __int__ and __trunc__ slots are examined.
1611
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001612- Issue #4893: Use NT threading on CE.
1613
Martin v. Löwisec59d042009-01-12 07:59:10 +00001614- Issue #4915: Port sysmodule to Windows CE.
1615
Antoine Pitrouab868312009-01-10 15:40:25 +00001616- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1617 common cases are optimized thanks to a dedicated fast path and a moderate
1618 amount of loop unrolling.
1619
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001620- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1621 collecting the oldest generation) so that allocating lots of objects without
1622 destroying them does not show quadratic performance. Based on a proposal by
1623 Martin von Löwis at
1624 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1625
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001626- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001627 having been closed (for instance, a read() call could return some
1628 previously buffered data). Patch by Dmitry Vasiliev.
1629
Antoine Pitrou05608432009-01-09 18:53:14 +00001630- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1631 flag to work properly. Furthermore, when specifying -u, the text stdout
1632 and stderr streams have line-by-line buffering enabled (the default being
1633 to buffer arbitrary chunks of data).
1634
Raymond Hettinger35631532009-01-09 03:58:09 +00001635- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1636 instead of ints (reducing its size from 4 to 8 times thereby reducing
1637 Python's overall memory).
1638
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001639- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1640 an existing .py counterpart, override the co_filename attributes of all
1641 code objects if the original filename is obsolete (which can happen if the
1642 file has been renamed, moved, or if it is accessed through different paths).
1643 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1644
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001645- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1646 one byte. Also fixes the meaning of len() so that it returns the number of
1647 items, rather than the size in bytes.
1648
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001649- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1650
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001651- Issue #4747: When the terminal does not use utf-8, executing a script with
1652 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1653
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001654- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001655 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001656
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001657- Issue #3680: Reference cycles created through a dict, set or deque iterator
1658 did not get collected.
1659
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001660- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1661 where the tp_hash and tp_dict slots are both NULL.
1662
Georg Brandlccc47b62008-12-28 11:44:14 +00001663- Issue #4759: None is now allowed as the first argument of
1664 bytearray.translate(). It was always allowed for bytes.translate().
1665
Skip Montanaro80072cb2008-12-23 03:51:14 +00001666- Added test case to ensure attempts to read from a file opened for writing
1667 fail.
1668
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001669- Issue #3106: Speedup some comparisons (str/str and int/int).
1670
Antoine Pitrouf289ae62008-12-18 11:06:25 +00001671- Issue #2183: Simplify and optimize bytecode for list, dict and set
1672 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1673
Antoine Pitrou621601a2008-12-17 23:18:19 +00001674- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1675 print elapsed times, not only when some objects are uncollectable /
1676 unreachable. Original patch by Neil Schemenauer.
1677
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001678- Issue #3439: Add a bit_length method to int.
1679
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001680- Issue #2173: When getting device encoding, check that return value of
1681 nl_langinfo is not the empty string. This was causing silent build
1682 failures on OS X.
1683
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001684- Issue #4597: Fixed several opcodes that weren't always propagating
1685 exceptions.
1686
1687- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001688 context manager returns a value that cannot be converted to a bool.
1689
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001690- Issue #4445: Replace "sizeof(PyBytesObject)" with
1691 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1692 bytes instances. On a typical machine this saves 3 bytes of memory
1693 (on average) per allocation of a bytes instance.
1694
Christian Heimesa872de52008-12-05 08:26:55 +00001695- Issue #4533: File read operation was dreadfully slow due to a slowly
1696 growing read buffer. Fixed by using the same growth rate algorithm as
1697 Python 2.x.
1698
Antoine Pitrou5504e892008-12-06 21:27:53 +00001699- Issue #4509: Various issues surrounding resize of bytearray objects to
1700 which there are buffer exports (e.g. memoryview instances).
1701
Georg Brandlf9734072008-12-07 15:30:06 +00001702- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1703 method on file objects with closefd=False. The file descriptor is still
1704 kept open but the file object behaves like a closed file. The ``FileIO``
1705 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001706
Antoine Pitroubc420402008-12-07 20:14:49 +00001707- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1708 larger than 1.

1713
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001714- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1715 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1716 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1717 of using the replace error handler in PyUnicode_DecodeUTF8().
