169 Decimal operation raises multiple signals and more than one of those
170 signals is trapped, the specification determines the order in which
171 the signals should be handled. In many cases this order wasn't
172 being followed, leading to the wrong Python exception being raised.
173
Antoine Pitroufaf90072010-05-03 16:58:19 +0000174- Issue #7865: The close() method of :mod:`io` objects should not swallow

203 witnessed in test_httpservers.
204
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000205- Issue #8524: When creating an SSL socket, the timeout value of the
206 original socket wasn't retained (instead, a socket with a positive timeout
207 would be turned into a non-blocking SSL socket).
208
Antoine Pitrouec146182010-04-24 21:30:20 +0000209- Issue #5103: SSL handshake would ignore the socket timeout and block
210 indefinitely if the other end didn't respond.

213 the SSL structure if necessary (as other methods already do).
214
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000215- Issue #8108: Fix the unwrap() method of SSL objects when the socket has

Victor Stinnerf7351b42010-04-13 11:09:22 +0000246- Issue #8383: pickle and pickletools use surrogatepass error handler when
247 encoding unicode as utf8 to support lone surrogates and stay compatible with
248 Python 2.x and 3.0
249
Florent Xicluna9b0e9182010-03-28 11:42:38 +0000250- Issue #8179: Fix macpath.realpath() on a non-existing path.

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

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001208
1209Core and Builtins
1210-----------------
1211
Mark Dickinson865e01a2009-05-07 16:37:01 +00001212- Issue #5914: Add new C API function PyOS_string_to_double, and
1213 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1214
Eric Smith741191f2009-05-06 13:08:15 +00001215- Issue #3382: float.__format__, complex.__format__, and %-formatting
1216 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1217 affects nan -> NAN and inf -> INF.
1218
Mark Hammond5a607a32009-05-06 08:04:54 +00001219- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1220 in all operations, including splitdrive, split, etc. splitunc() now issues
1221 a PendingDeprecation warning.
1222
Eric Smith63376222009-05-05 14:04:18 +00001223- Issue #5920: For float.__format__, change the behavior with the
1224 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1225 to be like 'g' but with at least one decimal point and with a
1226 default precision of 12. Previously, the behavior the same but with
1227 a default precision of 6. This more closely matches str(), and
1228 reduces surprises when adding alignment flags to the empty
1229 presentation type. This also affects the new complex.__format__ in
1230 the same way.
1231
Martin v. Löwis011e8422009-05-05 04:43:17 +00001232- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1233
R. David Murrayb18500d2009-05-04 22:59:07 +00001234- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1235 shadowed by classtype's, even if it was None. property now
1236 inserts the __doc__ into the subclass instance __dict__.
1237
Antoine Pitrou244651a2009-05-04 18:56:13 +00001238- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1239 sequences. Patch by Nick Barnes and Victor Stinner.
1240
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001241- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001242
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001243- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1244 received a new method, detach(). detach() disconnects the underlying stream
1245 from the buffer or text IO and returns it.
1246
Mark Dickinson33841c32009-05-01 15:37:04 +00001247- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1248 floats with absolute value over 1e50. Also remove length
1249 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1250 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001251
Eric Smith741191f2009-05-06 13:08:15 +00001252- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001253 format(complex(1, 2./3), '.5') now produces a sensible result.
1254
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001255- Issue #5864: Fix empty format code formatting for floats so that it
1256 never gives more than the requested number of significant digits.
1257
Eric Smith6dc46f52009-04-27 20:39:49 +00001258- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1259 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1260
Eric Smithcc32a112009-04-26 21:35:14 +00001261- Issue #5835: Deprecate PyOS_ascii_formatd.
1262
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001263- Issue #4971: Fix titlecase for characters that are their own
1264 titlecase, but not their own uppercase.
1265
Benjamin Peterson193152c2009-04-25 01:08:45 +00001266- Issue #5283: Setting __class__ in __del__ caused a segfault.
1267
Mark Dickinsonad476da2009-04-23 19:14:16 +00001268- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1269 z involves nans, infs or negative zeros.
1270
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001271- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001272
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001273- Issue #1869 (and many duplicates): make round(x, n) correctly
1274 rounded for a float x, by using the decimal <-> binary conversions
1275 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1276 consistently agrees with format(x, '.2f').
1277
Benjamin Petersonae937c02009-04-18 20:54:08 +00001278- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1279 some builtin types.
1280
Eric Smith0923d1d2009-04-16 20:16:10 +00001281- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1282
Eric Smith35e84722009-04-16 20:21:28 +00001283- Issue #5515: str.format() type 'n' combined with commas and leading
1284 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001285
1286- Implement PEP 378, Format Specifier for Thousands Separator, for
1287 floats.
1288
Mark Dickinson3370cce2009-04-17 22:40:53 +00001289- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001290 1e11, not 1e12. This avoids printing 13 significant digits in
1291 situations where only 12 of them are correct. Example problem
1292 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1293 long time.)
1294
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001295- Issue #1580: On most platforms, use a 'short' float repr: for a
1296 finite float x, repr(x) now outputs a string based on the shortest
1297 sequence of decimal digits that rounds to x. Previous behaviour was
1298 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001299 Another minor difference is that the new repr switches to
1300 exponential notation at 1e16 instead of the previous 1e17; this
1301 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001302
1303 There's a new sys attribute sys.float_repr_style, which takes
1304 the value 'short' to indicate that we're using short float repr,
1305 and 'legacy' if the short float repr isn't available for one
1306 reason or another.
1307
1308 The float repr change involves incorporating David Gay's 'perfect
1309 rounding' code into the Python core (it's in Python/dtoa.c). As a
1310 secondary consequence, all string-to-float and float-to-string
1311 conversions (including all float formatting operations) will be
1312 correctly rounded on these platforms.
1313
1314 See issue 1580 discussions for details of platforms for which
1315 this change does not apply.
1316
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001317- Issue #5759: float() didn't call __float__ on str subclasses.
1318
Georg Brandlabc38772009-04-12 15:51:51 +00001319- The string.maketrans() function is deprecated; there is a new static method
1320 maketrans() on the bytes and bytearray classes. This removes confusion about
1321 the types string.maketrans() is supposed to work with, and mirrors the
1322 methods available on the str class.
1323
R. David Murraydc6da8a2009-04-09 22:16:43 +00001324- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1325 its clarity and its speed.
1326
Matthias Klose091c7b12009-04-07 13:24:27 +00001327- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1328 to avoid compiler warnings.
1329
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001330- Issue #3739: The unicode-internal encoder now reports the number of characters
1331 consumed like any other encoder (instead of the number of bytes).

1475
Georg Brandlab6f2f62009-03-31 04:16:10 +00001476- Fix a segfault when running test_exceptions with coverage, caused by
1477 insufficient checks in accessors of Exception.__context__.
1478
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001479- Issue #5604: non-ASCII characters in module name passed to
1480 imp.find_module() were converted to UTF-8 while the path is
1481 converted to the default filesystem encoding, causing nonsense.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001485- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1486 the end sys.path, for compatibility with the system install of Python.
1487
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001488- Issue #4688: Add a heuristic so that tuples and dicts containing only
1489 untrackable objects are not tracked by the garbage collector. This can
1490 reduce the size of collections and therefore the garbage collection overhead
1491 on long-running programs, depending on their particular use of datatypes.
1492
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001493- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
1494 improve its performance. Long divisions and remainder operations
1495 are now between 50% and 150% faster.
1496
Mark Dickinsonbd792642009-03-18 20:06:12 +00001497- Issue #4258: Make it possible to use base 2**30 instead of base
1498 2**15 for the internal representation of integers, for performance
1499 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1500 --enable-big-digits option to configure, which overrides the
1501 default. Add sys.int_info structseq to provide information about
1502 the internal format.
1503
Mark Dickinson081dfee2009-03-18 14:47:41 +00001504- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1505 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1506 and sizeof(Py_UNICODE) == 2.
1507
Eric Smith8ec90442009-03-14 12:29:34 +00001508- Issue #5237: Allow auto-numbered fields in str.format(). For

1510
Antoine Pitrou652e7072009-03-13 19:25:20 +00001511- Issue #5392: when a very low recursion limit was set, the interpreter would
1512 abort with a fatal error after the recursion limit was hit twice.
1513
Matthias Klose042f1332009-04-04 14:32:42 +00001514- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1560
Lars Gustäbel42e00912009-03-22 20:34:29 +00001561- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1562 forever on incomplete input. That caused tarfile.open() to hang when used
1563 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

1612 rotating the object pointer by 4 bits to the right.
1613
Mark Dickinson87ec0852009-02-09 17:15:59 +00001614- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1615 it now forces its argument to double before testing for infinity.
1616
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001617- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1618 returns a non-number type.
1619

Mark Dickinsone94c6792009-02-02 20:36:42 +00001624 the type definition cmpfunc. The tp_compare slot has been renamed
1625 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001626
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001627- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001628 were suppressing all exceptions. These include list() and bytearray().
1629
Mark Dickinson1124e712009-01-28 21:25:58 +00001630- Issue #4707: round(x, n) now returns an integer if x is an integer.
1631 Previously it returned a float.
1632
Antoine Pitroub52ec782009-01-25 16:34:23 +00001633- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1634 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1635 evaluation loop is compiled with a new dispatch mechanism which gives
1636 speedups of up to 20%, depending on the system, on various benchmarks.
1637
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001638- Issue #4874: Most builtin decoders now reject unicode input.

1644
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001645- Issue #4838: When a module is deallocated, free the memory backing the
1646 optional module state data.
1647
Mark Dickinson8055afd2009-01-17 10:04:45 +00001648- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1649 type to (void *).
1650
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001651- Issue #4935: The overflow checking code in the expandtabs() method common
1652 to str, bytes and bytearray could be optimized away by the compiler, letting
1653 the interpreter segfault instead of raising an error.
1654
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001655- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1656 __next__ method.
1657
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001658- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1665
Antoine Pitrouab868312009-01-10 15:40:25 +00001666- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1667 common cases are optimized thanks to a dedicated fast path and a moderate
1668 amount of loop unrolling.
1669
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001670- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1671 collecting the oldest generation) so that allocating lots of objects without
1672 destroying them does not show quadratic performance. Based on a proposal by
1673 Martin von Löwis at
1674 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1675
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001676- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001677 having been closed (for instance, a read() call could return some
1678 previously buffered data). Patch by Dmitry Vasiliev.
1679
Antoine Pitrou05608432009-01-09 18:53:14 +00001680- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1681 flag to work properly. Furthermore, when specifying -u, the text stdout
1682 and stderr streams have line-by-line buffering enabled (the default being
1683 to buffer arbitrary chunks of data).
1684
Raymond Hettinger35631532009-01-09 03:58:09 +00001685- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1686 instead of ints (reducing its size from 4 to 8 times thereby reducing
1687 Python's overall memory).
1688
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001689- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1690 an existing .py counterpart, override the co_filename attributes of all
1691 code objects if the original filename is obsolete (which can happen if the
1692 file has been renamed, moved, or if it is accessed through different paths).
1693 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1694
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001695- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1696 one byte. Also fixes the meaning of len() so that it returns the number of
1697 items, rather than the size in bytes.
1698
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001699- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1700
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001701- Issue #4747: When the terminal does not use utf-8, executing a script with
1702 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1703
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001704- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001705 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001706
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001707- Issue #3680: Reference cycles created through a dict, set or deque iterator
1708 did not get collected.
1709
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001710- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1711 where the tp_hash and tp_dict slots are both NULL.
1712
Georg Brandlccc47b62008-12-28 11:44:14 +00001713- Issue #4759: None is now allowed as the first argument of
1714 bytearray.translate(). It was always allowed for bytes.translate().
1715
Skip Montanaro80072cb2008-12-23 03:51:14 +00001716- Added test case to ensure attempts to read from a file opened for writing
1717 fail.
1718
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001719- Issue #3106: Speedup some comparisons (str/str and int/int).

1722 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1723
Antoine Pitrou621601a2008-12-17 23:18:19 +00001724- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1725 print elapsed times, not only when some objects are uncollectable /
1726 unreachable. Original patch by Neil Schemenauer.
1727
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001728- Issue #3439: Add a bit_length method to int.
1729
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001730- Issue #2173: When getting device encoding, check that return value of
1731 nl_langinfo is not the empty string. This was causing silent build
1732 failures on OS X.
1733
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001734- Issue #4597: Fixed several opcodes that weren't always propagating
1735 exceptions.
1736
1737- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001738 context manager returns a value that cannot be converted to a bool.
1739
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001740- Issue #4445: Replace "sizeof(PyBytesObject)" with
1741 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1742 bytes instances. On a typical machine this saves 3 bytes of memory
1743 (on average) per allocation of a bytes instance.
1744
Christian Heimesa872de52008-12-05 08:26:55 +00001745- Issue #4533: File read operation was dreadfully slow due to a slowly
1746 growing read buffer. Fixed by using the same growth rate algorithm as
1747 Python 2.x.
1748
Antoine Pitrou5504e892008-12-06 21:27:53 +00001749- Issue #4509: Various issues surrounding resize of bytearray objects to
1750 which there are buffer exports (e.g. memoryview instances).
1751
Georg Brandlf9734072008-12-07 15:30:06 +00001752- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1753 method on file objects with closefd=False. The file descriptor is still
1754 kept open but the file object behaves like a closed file. The ``FileIO``
1755 object also got a new readonly attribute ``closefd``.
