164 witnessed in test_httpservers.
165
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000166- Issue #8524: When creating an SSL socket, the timeout value of the
167 original socket wasn't retained (instead, a socket with a positive timeout
168 would be turned into a non-blocking SSL socket).
169
Antoine Pitrouec146182010-04-24 21:30:20 +0000170- Issue #5103: SSL handshake would ignore the socket timeout and block

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

1174 default precision of 12. Previously, the behavior the same but with
1175 a default precision of 6. This more closely matches str(), and
1176 reduces surprises when adding alignment flags to the empty
1177 presentation type. This also affects the new complex.__format__ in
1178 the same way.

Martin v. Löwis011e8422009-05-05 04:43:17 +00001180- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1181
R. David Murrayb18500d2009-05-04 22:59:07 +00001182- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1183 shadowed by classtype's, even if it was None. property now
1184 inserts the __doc__ into the subclass instance __dict__.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001191- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1192 received a new method, detach(). detach() disconnects the underlying stream
1193 from the buffer or text IO and returns it.
1194
Mark Dickinson33841c32009-05-01 15:37:04 +00001195- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1196 floats with absolute value over 1e50. Also remove length
1197 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1198 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001199
Eric Smith741191f2009-05-06 13:08:15 +00001200- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001201 format(complex(1, 2./3), '.5') now produces a sensible result.
1202
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001203- Issue #5864: Fix empty format code formatting for floats so that it
1204 never gives more than the requested number of significant digits.
1205
Eric Smith6dc46f52009-04-27 20:39:49 +00001206- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1212 titlecase, but not their own uppercase.
1213
Benjamin Peterson193152c2009-04-25 01:08:45 +00001214- Issue #5283: Setting __class__ in __del__ caused a segfault.
1215
Mark Dickinsonad476da2009-04-23 19:14:16 +00001216- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1217 z involves nans, infs or negative zeros.
1218
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001219- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001220
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001221- Issue #1869 (and many duplicates): make round(x, n) correctly
1222 rounded for a float x, by using the decimal <-> binary conversions
1223 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1224 consistently agrees with format(x, '.2f').
1225
Benjamin Petersonae937c02009-04-18 20:54:08 +00001226- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1227 some builtin types.
1228
Eric Smith0923d1d2009-04-16 20:16:10 +00001229- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1230
Eric Smith35e84722009-04-16 20:21:28 +00001231- Issue #5515: str.format() type 'n' combined with commas and leading
1232 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001233
1234- Implement PEP 378, Format Specifier for Thousands Separator, for
1235 floats.
1236
Mark Dickinson3370cce2009-04-17 22:40:53 +00001237- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001238 1e11, not 1e12. This avoids printing 13 significant digits in
1239 situations where only 12 of them are correct. Example problem
1240 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1241 long time.)
1242
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001243- Issue #1580: On most platforms, use a 'short' float repr: for a
1244 finite float x, repr(x) now outputs a string based on the shortest
1245 sequence of decimal digits that rounds to x. Previous behaviour was
1246 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001247 Another minor difference is that the new repr switches to
1248 exponential notation at 1e16 instead of the previous 1e17; this
1249 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001250
1251 There's a new sys attribute sys.float_repr_style, which takes
1252 the value 'short' to indicate that we're using short float repr,
1253 and 'legacy' if the short float repr isn't available for one
1254 reason or another.
1255
1256 The float repr change involves incorporating David Gay's 'perfect
1257 rounding' code into the Python core (it's in Python/dtoa.c). As a
1258 secondary consequence, all string-to-float and float-to-string
1259 conversions (including all float formatting operations) will be
1260 correctly rounded on these platforms.
1261
1262 See issue 1580 discussions for details of platforms for which
1263 this change does not apply.
1264
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001265- Issue #5759: float() didn't call __float__ on str subclasses.
1266
Georg Brandlabc38772009-04-12 15:51:51 +00001267- The string.maketrans() function is deprecated; there is a new static method
1268 maketrans() on the bytes and bytearray classes. This removes confusion about
1269 the types string.maketrans() is supposed to work with, and mirrors the
1270 methods available on the str class.
1271
R. David Murraydc6da8a2009-04-09 22:16:43 +00001272- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1276 to avoid compiler warnings.
1277
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001278- Issue #3739: The unicode-internal encoder now reports the number of characters

1435
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001436- Issue #4688: Add a heuristic so that tuples and dicts containing only
1437 untrackable objects are not tracked by the garbage collector. This can
1438 reduce the size of collections and therefore the garbage collection overhead
1439 on long-running programs, depending on their particular use of datatypes.

1453 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1454 and sizeof(Py_UNICODE) == 2.
1455
Eric Smith8ec90442009-03-14 12:29:34 +00001456- Issue #5237: Allow auto-numbered fields in str.format(). For

1560 rotating the object pointer by 4 bits to the right.
1561
Mark Dickinson87ec0852009-02-09 17:15:59 +00001562- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1563 it now forces its argument to double before testing for infinity.
1564
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001565- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1566 returns a non-number type.
1567
Benjamin Peterson87618552009-02-08 15:00:52 +00001568- Issue #5182: Removed memoryview.__str__.

1573 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001574
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001575- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001576 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00001578- Issue #4707: round(x, n) now returns an integer if x is an integer.
1579 Previously it returned a float.
1580
Antoine Pitroub52ec782009-01-25 16:34:23 +00001581- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1582 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1583 evaluation loop is compiled with a new dispatch mechanism which gives
1584 speedups of up to 20%, depending on the system, on various benchmarks.
1585
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001586- Issue #4874: Most builtin decoders now reject unicode input.

1592
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001593- Issue #4838: When a module is deallocated, free the memory backing the
1594 optional module state data.
1595
Mark Dickinson8055afd2009-01-17 10:04:45 +00001596- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1597 type to (void *).
1598
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001599- Issue #4935: The overflow checking code in the expandtabs() method common
1600 to str, bytes and bytearray could be optimized away by the compiler, letting
1601 the interpreter segfault instead of raising an error.
1602
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001603- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1604 __next__ method.
1605
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001606- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1607 function no longer attempt to call the __long__ slot to convert an object
1608 to an integer. Only the __int__ and __trunc__ slots are examined.
1609
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001610- Issue #4893: Use NT threading on CE.
1611
Martin v. Löwisec59d042009-01-12 07:59:10 +00001612- Issue #4915: Port sysmodule to Windows CE.
1613
Antoine Pitrouab868312009-01-10 15:40:25 +00001614- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1615 common cases are optimized thanks to a dedicated fast path and a moderate
1616 amount of loop unrolling.
1617
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001618- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1619 collecting the oldest generation) so that allocating lots of objects without
1620 destroying them does not show quadratic performance. Based on a proposal by
1621 Martin von Löwis at
1622 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1623
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001624- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001625 having been closed (for instance, a read() call could return some
1626 previously buffered data). Patch by Dmitry Vasiliev.
1627
Antoine Pitrou05608432009-01-09 18:53:14 +00001628- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1629 flag to work properly. Furthermore, when specifying -u, the text stdout
1630 and stderr streams have line-by-line buffering enabled (the default being
1631 to buffer arbitrary chunks of data).
1632
Raymond Hettinger35631532009-01-09 03:58:09 +00001633- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1634 instead of ints (reducing its size from 4 to 8 times thereby reducing
1635 Python's overall memory).
1636
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001637- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1638 an existing .py counterpart, override the co_filename attributes of all
1639 code objects if the original filename is obsolete (which can happen if the
1640 file has been renamed, moved, or if it is accessed through different paths).
1641 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1642
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001643- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1644 one byte. Also fixes the meaning of len() so that it returns the number of
1645 items, rather than the size in bytes.
1646
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001647- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1648
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001649- Issue #4747: When the terminal does not use utf-8, executing a script with
1650 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1651
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001652- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001653 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001654
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001655- Issue #3680: Reference cycles created through a dict, set or deque iterator
1656 did not get collected.
1657
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001658- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1659 where the tp_hash and tp_dict slots are both NULL.
1660
Georg Brandlccc47b62008-12-28 11:44:14 +00001661- Issue #4759: None is now allowed as the first argument of
1662 bytearray.translate(). It was always allowed for bytes.translate().
1663
Skip Montanaro80072cb2008-12-23 03:51:14 +00001664- Added test case to ensure attempts to read from a file opened for writing
1665 fail.
1666
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001667- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00001669- Issue #2183: Simplify and optimize bytecode for list, dict and set
1670 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1671
Antoine Pitrou621601a2008-12-17 23:18:19 +00001672- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1673 print elapsed times, not only when some objects are uncollectable /
1674 unreachable. Original patch by Neil Schemenauer.
1675
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001676- Issue #3439: Add a bit_length method to int.
1677
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001678- Issue #2173: When getting device encoding, check that return value of
1679 nl_langinfo is not the empty string. This was causing silent build
1680 failures on OS X.
1681
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001682- Issue #4597: Fixed several opcodes that weren't always propagating
1683 exceptions.
1684
1685- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001686 context manager returns a value that cannot be converted to a bool.
1687
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001688- Issue #4445: Replace "sizeof(PyBytesObject)" with
1689 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1690 bytes instances. On a typical machine this saves 3 bytes of memory
1691 (on average) per allocation of a bytes instance.
1692
Christian Heimesa872de52008-12-05 08:26:55 +00001693- Issue #4533: File read operation was dreadfully slow due to a slowly
1694 growing read buffer. Fixed by using the same growth rate algorithm as
1695 Python 2.x.
1696
Antoine Pitrou5504e892008-12-06 21:27:53 +00001697- Issue #4509: Various issues surrounding resize of bytearray objects to
1698 which there are buffer exports (e.g. memoryview instances).
1699
Georg Brandlf9734072008-12-07 15:30:06 +00001700- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1701 method on file objects with closefd=False. The file descriptor is still
1702 kept open but the file object behaves like a closed file. The ``FileIO``
1703 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001704
Antoine Pitroubc420402008-12-07 20:14:49 +00001705- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001712- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1713 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1714 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1715 of using the replace error handler in PyUnicode_DecodeUTF8().
