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

121 witnessed in test_httpservers.
122
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000123- Issue #8524: When creating an SSL socket, the timeout value of the
124 original socket wasn't retained (instead, a socket with a positive timeout
125 would be turned into a non-blocking SSL socket).
126
Antoine Pitrouec146182010-04-24 21:30:20 +0000127- Issue #5103: SSL handshake would ignore the socket timeout and block
128 indefinitely if the other end didn't respond.
129
130- The do_handshake() method of SSL objects now adjusts the blocking mode of
131 the SSL structure if necessary (as other methods already do).

134 a non-infinite timeout. Also make that method friendlier with applications
135 wanting to continue using the socket in clear-text mode, by disabling
136 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

139
Antoine Pitrouf9433fe2010-04-22 13:56:42 +0000140- Issue #8496: make mailcap.lookup() always return a list, rather than an

147 the _ssl extension, such that verification of some SSL certificates

149
Giampaolo Rodolàf5279402010-04-19 22:10:56 +0000150- Issue #4814: timeout parameter is now applied also for connections resulting

160 using backslashreplace error handler
161
R. David Murray84ee3102010-04-14 19:05:38 +0000162- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
163
Victor Stinnerf7351b42010-04-13 11:09:22 +0000164- Issue #8383: pickle and pickletools use surrogatepass error handler when

166 Python 2.x and 3.0
167
Florent Xicluna9b0e9182010-03-28 11:42:38 +0000168- Issue #8179: Fix macpath.realpath() on a non-existing path.
169
Antoine Pitrou9004edd2010-03-23 00:28:26 +0000170- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

172 Initial patch by Bertrand Janin.
173
Antoine Pitrou9f274b12010-03-22 20:12:40 +0000174- Issue #7512: shutil.copystat() could raise an OSError when the filesystem

180 reads and writes are always retried by OpenSSL itself.

Antoine Pitrou452a5802010-05-06 13:54:43 +0000203- Issue #8629: Disable some test_ssl tests, since they give different

Mark Dickinson865e01a2009-05-07 16:37:01 +00001109- Issue #5914: Add new C API function PyOS_string_to_double, and
1110 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1111
Eric Smith741191f2009-05-06 13:08:15 +00001112- Issue #3382: float.__format__, complex.__format__, and %-formatting
1113 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

1119
Eric Smith63376222009-05-05 14:04:18 +00001120- Issue #5920: For float.__format__, change the behavior with the
1121 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1122 to be like 'g' but with at least one decimal point and with a
1123 default precision of 12. Previously, the behavior the same but with
1124 a default precision of 6. This more closely matches str(), and
1125 reduces surprises when adding alignment flags to the empty
1126 presentation type. This also affects the new complex.__format__ in
1127 the same way.

1141 received a new method, detach(). detach() disconnects the underlying stream
1142 from the buffer or text IO and returns it.
1143
Mark Dickinson33841c32009-05-01 15:37:04 +00001144- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1145 floats with absolute value over 1e50. Also remove length
1146 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001168- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001169
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001170- Issue #1869 (and many duplicates): make round(x, n) correctly
1171 rounded for a float x, by using the decimal <-> binary conversions
1172 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1173 consistently agrees with format(x, '.2f').
1174
Benjamin Petersonae937c02009-04-18 20:54:08 +00001175- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1176 some builtin types.
1177
Eric Smith0923d1d2009-04-16 20:16:10 +00001178- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1179
Eric Smith35e84722009-04-16 20:21:28 +00001180- Issue #5515: str.format() type 'n' combined with commas and leading
1181 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001182
1183- Implement PEP 378, Format Specifier for Thousands Separator, for
1184 floats.
1185
Mark Dickinson3370cce2009-04-17 22:40:53 +00001186- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001187 1e11, not 1e12. This avoids printing 13 significant digits in
1188 situations where only 12 of them are correct. Example problem
1189 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1190 long time.)
1191
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001192- Issue #1580: On most platforms, use a 'short' float repr: for a
1193 finite float x, repr(x) now outputs a string based on the shortest
1194 sequence of decimal digits that rounds to x. Previous behaviour was
1195 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001196 Another minor difference is that the new repr switches to
1197 exponential notation at 1e16 instead of the previous 1e17; this
1198 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001199
1200 There's a new sys attribute sys.float_repr_style, which takes
1201 the value 'short' to indicate that we're using short float repr,
1202 and 'legacy' if the short float repr isn't available for one
1203 reason or another.
1204
1205 The float repr change involves incorporating David Gay's 'perfect
1206 rounding' code into the Python core (it's in Python/dtoa.c). As a
1207 secondary consequence, all string-to-float and float-to-string
1208 conversions (including all float formatting operations) will be
1209 correctly rounded on these platforms.
1210
1211 See issue 1580 discussions for details of platforms for which
1212 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001214- Issue #5759: float() didn't call __float__ on str subclasses.
1215
Georg Brandlabc38772009-04-12 15:51:51 +00001216- The string.maketrans() function is deprecated; there is a new static method
1217 maketrans() on the bytes and bytearray classes. This removes confusion about
1218 the types string.maketrans() is supposed to work with, and mirrors the
1219 methods available on the str class.
1220
R. David Murraydc6da8a2009-04-09 22:16:43 +00001221- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1384
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001385- Issue #4688: Add a heuristic so that tuples and dicts containing only
1386 untrackable objects are not tracked by the garbage collector. This can
1387 reduce the size of collections and therefore the garbage collection overhead
1388 on long-running programs, depending on their particular use of datatypes.

1396 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1397 --enable-big-digits option to configure, which overrides the
1398 default. Add sys.int_info structseq to provide information about
1399 the internal format.

1402 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1403 and sizeof(Py_UNICODE) == 2.
1404
Eric Smith8ec90442009-03-14 12:29:34 +00001405- Issue #5237: Allow auto-numbered fields in str.format(). For

1454
Benjamin Peterson59406a92009-03-26 17:10:29 +00001455- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1456 io.BufferedRandom have been deprecated for removal in Python 3.2.
1457
Lars Gustäbel42e00912009-03-22 20:34:29 +00001458- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1459 forever on incomplete input. That caused tarfile.open() to hang when used
1460 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1461 partial bzip2 compressed data.
1462
Mark Dickinson79f52032009-03-17 23:12:51 +00001463- Issue #2110: Add support for thousands separator and 'n' type

1481 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001482 struct.error instead of returning b'\xff\xff\xff\xff'. The
1483 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1484 have been removed from the struct module.

1503 contained non ascii character on windows.
1504
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001505- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1506 source has already been decoded into str.
1507
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001508- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1509 rotating the object pointer by 4 bits to the right.
1510
Mark Dickinson87ec0852009-02-09 17:15:59 +00001511- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1512 it now forces its argument to double before testing for infinity.
1513
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001514- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1515 returns a non-number type.
1516
Benjamin Peterson87618552009-02-08 15:00:52 +00001517- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001523
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001524- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001525 were suppressing all exceptions. These include list() and bytearray().
1526
Mark Dickinson1124e712009-01-28 21:25:58 +00001527- Issue #4707: round(x, n) now returns an integer if x is an integer.
1528 Previously it returned a float.
1529
Antoine Pitroub52ec782009-01-25 16:34:23 +00001530- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1531 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1532 evaluation loop is compiled with a new dispatch mechanism which gives
1533 speedups of up to 20%, depending on the system, on various benchmarks.
1534
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001535- Issue #4874: Most builtin decoders now reject unicode input.

1541
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001542- Issue #4838: When a module is deallocated, free the memory backing the
1543 optional module state data.
1544
Mark Dickinson8055afd2009-01-17 10:04:45 +00001545- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1546 type to (void *).
1547
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001548- Issue #4935: The overflow checking code in the expandtabs() method common
1549 to str, bytes and bytearray could be optimized away by the compiler, letting
1550 the interpreter segfault instead of raising an error.
1551
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001552- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1553 __next__ method.
1554
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001555- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1556 function no longer attempt to call the __long__ slot to convert an object
1557 to an integer. Only the __int__ and __trunc__ slots are examined.
1558
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001559- Issue #4893: Use NT threading on CE.
1560
Martin v. Löwisec59d042009-01-12 07:59:10 +00001561- Issue #4915: Port sysmodule to Windows CE.
1562
Antoine Pitrouab868312009-01-10 15:40:25 +00001563- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1564 common cases are optimized thanks to a dedicated fast path and a moderate
1565 amount of loop unrolling.
1566
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001567- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1568 collecting the oldest generation) so that allocating lots of objects without
1569 destroying them does not show quadratic performance. Based on a proposal by
1570 Martin von Löwis at
1571 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1572
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001573- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001574 having been closed (for instance, a read() call could return some
1575 previously buffered data). Patch by Dmitry Vasiliev.
1576
Antoine Pitrou05608432009-01-09 18:53:14 +00001577- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1578 flag to work properly. Furthermore, when specifying -u, the text stdout
1579 and stderr streams have line-by-line buffering enabled (the default being
1580 to buffer arbitrary chunks of data).
1581
Raymond Hettinger35631532009-01-09 03:58:09 +00001582- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1583 instead of ints (reducing its size from 4 to 8 times thereby reducing
1584 Python's overall memory).
1585
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001586- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1587 an existing .py counterpart, override the co_filename attributes of all
1588 code objects if the original filename is obsolete (which can happen if the
1589 file has been renamed, moved, or if it is accessed through different paths).
1590 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1591
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001592- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1593 one byte. Also fixes the meaning of len() so that it returns the number of
1594 items, rather than the size in bytes.
1595
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001596- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1597
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001598- Issue #4747: When the terminal does not use utf-8, executing a script with
1599 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1600
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001601- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001602 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001603
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001604- Issue #3680: Reference cycles created through a dict, set or deque iterator
1605 did not get collected.
1606
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001607- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1608 where the tp_hash and tp_dict slots are both NULL.
1609
Georg Brandlccc47b62008-12-28 11:44:14 +00001610- Issue #4759: None is now allowed as the first argument of
1611 bytearray.translate(). It was always allowed for bytes.translate().
1612
Skip Montanaro80072cb2008-12-23 03:51:14 +00001613- Added test case to ensure attempts to read from a file opened for writing
1614 fail.
1615
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001616- Issue #3106: Speedup some comparisons (str/str and int/int).

1619 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1620
Antoine Pitrou621601a2008-12-17 23:18:19 +00001621- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1622 print elapsed times, not only when some objects are uncollectable /
1623 unreachable. Original patch by Neil Schemenauer.
1624
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001625- Issue #3439: Add a bit_length method to int.
1626
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001627- Issue #2173: When getting device encoding, check that return value of
1628 nl_langinfo is not the empty string. This was causing silent build
1629 failures on OS X.
1630
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001631- Issue #4597: Fixed several opcodes that weren't always propagating
1632 exceptions.
1633
1634- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001635 context manager returns a value that cannot be converted to a bool.
1636
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001637- Issue #4445: Replace "sizeof(PyBytesObject)" with
1638 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1639 bytes instances. On a typical machine this saves 3 bytes of memory
1640 (on average) per allocation of a bytes instance.
1641
Christian Heimesa872de52008-12-05 08:26:55 +00001642- Issue #4533: File read operation was dreadfully slow due to a slowly
1643 growing read buffer. Fixed by using the same growth rate algorithm as
1644 Python 2.x.
1645
Antoine Pitrou5504e892008-12-06 21:27:53 +00001646- Issue #4509: Various issues surrounding resize of bytearray objects to
1647 which there are buffer exports (e.g. memoryview instances).
1648
Georg Brandlf9734072008-12-07 15:30:06 +00001649- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1650 method on file objects with closefd=False. The file descriptor is still
1651 kept open but the file object behaves like a closed file. The ``FileIO``
1652 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001653
Antoine Pitroubc420402008-12-07 20:14:49 +00001654- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1655 larger than 1.

1660
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001661- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1662 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1663 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1664 of using the replace error handler in PyUnicode_DecodeUTF8().
