Mark Dickinsonfc070312010-08-01 10:43:42 +000015- Issue #9416: Fix some issues with complex formatting where the
16 output with no type specifier failed to match the str output:
17
18 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
19 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
20

Ezio Melotti25bc0192010-07-03 05:18:50 +000024- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
25 start byte and the continuation byte(s) are now considered invalid, instead
26 of the number of bytes specified by the start byte.
27 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
28 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
29 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
30 Previous versions returned a single u'\ufffd'.
31

Antoine Pitrouc2203f92010-04-24 22:07:51 +0000293- Issue #8524: When creating an SSL socket, the timeout value of the
294 original socket wasn't retained (instead, a socket with a positive timeout
295 would be turned into a non-blocking SSL socket).
296
Antoine Pitrouec146182010-04-24 21:30:20 +0000297- Issue #5103: SSL handshake would ignore the socket timeout and block

1207 that would raise SystemError.
1208
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001209- Issue #5982: staticmethod and classmethod now expose the wrapped
1210 function with __func__.
1211
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001212- Added support for multiple context managers in the same with-statement.
1213 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001215- Issue #5829: complex("1e500") no longer raises OverflowError. This
1216 makes it consistent with float("1e500") and interpretation of real
1217 and imaginary literals.
1218
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001219- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

1222
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001223- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1224 (1) inf and nan strings with trailing whitespace were incorrectly
1225 rejected; (2) parsing of strings representing infinities and nans
1226 was locale aware; and (3) the interpretation of fromhex('-nan')
1227 didn't match that of float('-nan').

1243 names: cls, self, tuple, itemgetter, and property.
1244
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001245- In unittest, using a skipping decorator on a class is now equivalent to
1246 skipping every test on the class. The ClassTestSuite class has been removed.
1247
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001248- Issue #6050: Don't fail extracting a directory from a zipfile if
1249 the directory already exists.
1250
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001251- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1252 than an int, which makes some operations possible under 64-bit Linux (e.g.
1253 DN_MULTISHOT with F_NOTIFY).
1254
Antoine Pitrou716c4442009-05-23 19:04:03 +00001255- Issue #5761: Add the name of the underlying file to the repr() of various

1260
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001261- Issue #1983: Fix functions taking or returning a process identifier to use
1262 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1263 a process identifier type wider than the standard C integer type.
1264
R. David Murray87e20742009-05-23 01:30:26 +00001265- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1276
Antoine Pitroue4501852009-05-14 18:55:55 +00001277- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1278 library. This means, for example, that opening an UTF-16 text file in
1279 append mode doesn't add a BOM at the end of the file if the file isn't
1280 empty.
1281
R. David Murray74b89242009-05-13 17:33:03 +00001282- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1283 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1284 corrects a pydoc regression.
1285
R. David Murray99352742009-05-07 18:24:38 +00001286- Issue 5955: aifc's close method did not close the file it wrapped,
1287 now it does. This also means getfp method now returns the real fp.
1288

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001329
1330Core and Builtins
1331-----------------
1332
Mark Dickinson865e01a2009-05-07 16:37:01 +00001333- Issue #5914: Add new C API function PyOS_string_to_double, and
1334 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1335
Eric Smith741191f2009-05-06 13:08:15 +00001336- Issue #3382: float.__format__, complex.__format__, and %-formatting
1337 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1338 affects nan -> NAN and inf -> INF.
1339
Mark Hammond5a607a32009-05-06 08:04:54 +00001340- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1341 in all operations, including splitdrive, split, etc. splitunc() now issues
1342 a PendingDeprecation warning.
1343
Eric Smith63376222009-05-05 14:04:18 +00001344- Issue #5920: For float.__format__, change the behavior with the
1345 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1346 to be like 'g' but with at least one decimal point and with a
1347 default precision of 12. Previously, the behavior the same but with
1348 a default precision of 6. This more closely matches str(), and
1349 reduces surprises when adding alignment flags to the empty
1350 presentation type. This also affects the new complex.__format__ in
1351 the same way.
1352
Martin v. Löwis011e8422009-05-05 04:43:17 +00001353- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1354
R. David Murrayb18500d2009-05-04 22:59:07 +00001355- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1356 shadowed by classtype's, even if it was None. property now
1357 inserts the __doc__ into the subclass instance __dict__.
1358
Antoine Pitrou244651a2009-05-04 18:56:13 +00001359- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1360 sequences. Patch by Nick Barnes and Victor Stinner.
1361
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001362- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001363
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001364- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1365 received a new method, detach(). detach() disconnects the underlying stream
1366 from the buffer or text IO and returns it.
1367
Mark Dickinson33841c32009-05-01 15:37:04 +00001368- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1369 floats with absolute value over 1e50. Also remove length
1370 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1371 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001372
Eric Smith741191f2009-05-06 13:08:15 +00001373- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001374 format(complex(1, 2./3), '.5') now produces a sensible result.
1375
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001376- Issue #5864: Fix empty format code formatting for floats so that it
1377 never gives more than the requested number of significant digits.
1378
Eric Smith6dc46f52009-04-27 20:39:49 +00001379- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1380 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1381
Eric Smithcc32a112009-04-26 21:35:14 +00001382- Issue #5835: Deprecate PyOS_ascii_formatd.
1383
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001384- Issue #4971: Fix titlecase for characters that are their own
1385 titlecase, but not their own uppercase.
1386
Benjamin Peterson193152c2009-04-25 01:08:45 +00001387- Issue #5283: Setting __class__ in __del__ caused a segfault.
1388
Mark Dickinsonad476da2009-04-23 19:14:16 +00001389- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1390 z involves nans, infs or negative zeros.
1391
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001392- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001393
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001394- Issue #1869 (and many duplicates): make round(x, n) correctly
1395 rounded for a float x, by using the decimal <-> binary conversions
1396 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1397 consistently agrees with format(x, '.2f').
1398
Benjamin Petersonae937c02009-04-18 20:54:08 +00001399- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1400 some builtin types.
1401
Eric Smith0923d1d2009-04-16 20:16:10 +00001402- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1403
Eric Smith35e84722009-04-16 20:21:28 +00001404- Issue #5515: str.format() type 'n' combined with commas and leading
1405 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001406
1407- Implement PEP 378, Format Specifier for Thousands Separator, for
1408 floats.
1409
Mark Dickinson3370cce2009-04-17 22:40:53 +00001410- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001411 1e11, not 1e12. This avoids printing 13 significant digits in
1412 situations where only 12 of them are correct. Example problem
1413 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1414 long time.)
1415
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001416- Issue #1580: On most platforms, use a 'short' float repr: for a
1417 finite float x, repr(x) now outputs a string based on the shortest
1418 sequence of decimal digits that rounds to x. Previous behaviour was
1419 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001420 Another minor difference is that the new repr switches to
1421 exponential notation at 1e16 instead of the previous 1e17; this
1422 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001423
1424 There's a new sys attribute sys.float_repr_style, which takes
1425 the value 'short' to indicate that we're using short float repr,
1426 and 'legacy' if the short float repr isn't available for one
1427 reason or another.
1428
1429 The float repr change involves incorporating David Gay's 'perfect
1430 rounding' code into the Python core (it's in Python/dtoa.c). As a
1431 secondary consequence, all string-to-float and float-to-string
1432 conversions (including all float formatting operations) will be
1433 correctly rounded on these platforms.
1434
1435 See issue 1580 discussions for details of platforms for which
1436 this change does not apply.
1437
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001438- Issue #5759: float() didn't call __float__ on str subclasses.
1439
Georg Brandlabc38772009-04-12 15:51:51 +00001440- The string.maketrans() function is deprecated; there is a new static method
1441 maketrans() on the bytes and bytearray classes. This removes confusion about
1442 the types string.maketrans() is supposed to work with, and mirrors the
1443 methods available on the str class.
1444
R. David Murraydc6da8a2009-04-09 22:16:43 +00001445- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1446 its clarity and its speed.
1447
Matthias Klose091c7b12009-04-07 13:24:27 +00001448- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1449 to avoid compiler warnings.
1450
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001451- Issue #3739: The unicode-internal encoder now reports the number of characters
1452 consumed like any other encoder (instead of the number of bytes).

1767 optional module state data.
1768
Mark Dickinson8055afd2009-01-17 10:04:45 +00001769- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1770 type to (void *).
1771
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001772- Issue #4935: The overflow checking code in the expandtabs() method common
1773 to str, bytes and bytearray could be optimized away by the compiler, letting
1774 the interpreter segfault instead of raising an error.
1775
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001776- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1777 __next__ method.
1778
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001779- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1780 function no longer attempt to call the __long__ slot to convert an object
1781 to an integer. Only the __int__ and __trunc__ slots are examined.

1786
Antoine Pitrouab868312009-01-10 15:40:25 +00001787- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1788 common cases are optimized thanks to a dedicated fast path and a moderate
1789 amount of loop unrolling.
1790
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001791- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1792 collecting the oldest generation) so that allocating lots of objects without
1793 destroying them does not show quadratic performance. Based on a proposal by
1794 Martin von Löwis at
1795 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1796
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001797- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001798 having been closed (for instance, a read() call could return some
1799 previously buffered data). Patch by Dmitry Vasiliev.
1800
Antoine Pitrou05608432009-01-09 18:53:14 +00001801- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1802 flag to work properly. Furthermore, when specifying -u, the text stdout
1803 and stderr streams have line-by-line buffering enabled (the default being
1804 to buffer arbitrary chunks of data).
1805
Raymond Hettinger35631532009-01-09 03:58:09 +00001806- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1807 instead of ints (reducing its size from 4 to 8 times thereby reducing
1808 Python's overall memory).
1809
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001810- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1811 an existing .py counterpart, override the co_filename attributes of all
1812 code objects if the original filename is obsolete (which can happen if the
1813 file has been renamed, moved, or if it is accessed through different paths).
1814 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1815
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001816- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1817 one byte. Also fixes the meaning of len() so that it returns the number of
1818 items, rather than the size in bytes.
1819
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001820- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1821
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001822- Issue #4747: When the terminal does not use utf-8, executing a script with
1823 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1824
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001825- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1829 did not get collected.
1830
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001831- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1832 where the tp_hash and tp_dict slots are both NULL.
1833
Georg Brandlccc47b62008-12-28 11:44:14 +00001834- Issue #4759: None is now allowed as the first argument of
1835 bytearray.translate(). It was always allowed for bytes.translate().
1836
Skip Montanaro80072cb2008-12-23 03:51:14 +00001837- Added test case to ensure attempts to read from a file opened for writing
1838 fail.
1839

1843 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1844
Antoine Pitrou621601a2008-12-17 23:18:19 +00001845- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1847 unreachable. Original patch by Neil Schemenauer.
1848
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001849- Issue #3439: Add a bit_length method to int.
1850
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001851- Issue #2173: When getting device encoding, check that return value of
1852 nl_langinfo is not the empty string. This was causing silent build
1853 failures on OS X.
1854
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001855- Issue #4597: Fixed several opcodes that weren't always propagating
1856 exceptions.
1857
1858- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001859 context manager returns a value that cannot be converted to a bool.
1860
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001861- Issue #4445: Replace "sizeof(PyBytesObject)" with
1862 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1863 bytes instances. On a typical machine this saves 3 bytes of memory
1864 (on average) per allocation of a bytes instance.
1865
Christian Heimesa872de52008-12-05 08:26:55 +00001866- Issue #4533: File read operation was dreadfully slow due to a slowly
1867 growing read buffer. Fixed by using the same growth rate algorithm as
1868 Python 2.x.
1869
Antoine Pitrou5504e892008-12-06 21:27:53 +00001870- Issue #4509: Various issues surrounding resize of bytearray objects to
1871 which there are buffer exports (e.g. memoryview instances).
1872
Georg Brandlf9734072008-12-07 15:30:06 +00001873- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1874 method on file objects with closefd=False. The file descriptor is still
1875 kept open but the file object behaves like a closed file. The ``FileIO``
1876 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001877
Antoine Pitroubc420402008-12-07 20:14:49 +00001878- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1884
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001885- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1886 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1887 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1888 of using the replace error handler in PyUnicode_DecodeUTF8().

2167 do an explicit seek to the end of file (so that e.g. tell() returns the
