Ezio Melotti25bc0192010-07-03 05:18:50 +000018- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
19 start byte and the continuation byte(s) are now considered invalid, instead
20 of the number of bytes specified by the start byte.
21 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
22 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
23 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
24 Previous versions returned a single u'\ufffd'.

41
Victor Stinner2e71d012010-05-17 09:35:44 +000042- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace

256 original socket wasn't retained (instead, a socket with a positive timeout
257 would be turned into a non-blocking SSL socket).
258
Antoine Pitrouec146182010-04-24 21:30:20 +0000259- Issue #5103: SSL handshake would ignore the socket timeout and block

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001174- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1175 (1) inf and nan strings with trailing whitespace were incorrectly
1176 rejected; (2) parsing of strings representing infinities and nans
1177 was locale aware; and (3) the interpretation of fromhex('-nan')
1178 didn't match that of float('-nan').

1281Core and Builtins
1282-----------------
1283
Mark Dickinson865e01a2009-05-07 16:37:01 +00001284- Issue #5914: Add new C API function PyOS_string_to_double, and
1285 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1286
Eric Smith741191f2009-05-06 13:08:15 +00001287- Issue #3382: float.__format__, complex.__format__, and %-formatting
1288 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1289 affects nan -> NAN and inf -> INF.
1290
Mark Hammond5a607a32009-05-06 08:04:54 +00001291- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1292 in all operations, including splitdrive, split, etc. splitunc() now issues
1293 a PendingDeprecation warning.
1294
Eric Smith63376222009-05-05 14:04:18 +00001295- Issue #5920: For float.__format__, change the behavior with the
1296 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1297 to be like 'g' but with at least one decimal point and with a
1298 default precision of 12. Previously, the behavior the same but with
1299 a default precision of 6. This more closely matches str(), and
1300 reduces surprises when adding alignment flags to the empty
1301 presentation type. This also affects the new complex.__format__ in
1302 the same way.
1303
Martin v. Löwis011e8422009-05-05 04:43:17 +00001304- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1305
R. David Murrayb18500d2009-05-04 22:59:07 +00001306- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1307 shadowed by classtype's, even if it was None. property now
1308 inserts the __doc__ into the subclass instance __dict__.
1309
Antoine Pitrou244651a2009-05-04 18:56:13 +00001310- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1311 sequences. Patch by Nick Barnes and Victor Stinner.
1312
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001313- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001314
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001315- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1316 received a new method, detach(). detach() disconnects the underlying stream
1317 from the buffer or text IO and returns it.
1318
Mark Dickinson33841c32009-05-01 15:37:04 +00001319- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1320 floats with absolute value over 1e50. Also remove length
1321 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1322 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001323
Eric Smith741191f2009-05-06 13:08:15 +00001324- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001325 format(complex(1, 2./3), '.5') now produces a sensible result.
1326
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001327- Issue #5864: Fix empty format code formatting for floats so that it
1328 never gives more than the requested number of significant digits.
1329
Eric Smith6dc46f52009-04-27 20:39:49 +00001330- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1331 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1332
Eric Smithcc32a112009-04-26 21:35:14 +00001333- Issue #5835: Deprecate PyOS_ascii_formatd.
1334
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001335- Issue #4971: Fix titlecase for characters that are their own
1336 titlecase, but not their own uppercase.
1337
Benjamin Peterson193152c2009-04-25 01:08:45 +00001338- Issue #5283: Setting __class__ in __del__ caused a segfault.
1339
Mark Dickinsonad476da2009-04-23 19:14:16 +00001340- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1341 z involves nans, infs or negative zeros.
1342
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001343- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001344
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001345- Issue #1869 (and many duplicates): make round(x, n) correctly
1346 rounded for a float x, by using the decimal <-> binary conversions
1347 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1348 consistently agrees with format(x, '.2f').
1349
Benjamin Petersonae937c02009-04-18 20:54:08 +00001350- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1351 some builtin types.
1352
Eric Smith0923d1d2009-04-16 20:16:10 +00001353- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1354
Eric Smith35e84722009-04-16 20:21:28 +00001355- Issue #5515: str.format() type 'n' combined with commas and leading
1356 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001357
1358- Implement PEP 378, Format Specifier for Thousands Separator, for
1359 floats.
1360
Mark Dickinson3370cce2009-04-17 22:40:53 +00001361- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001362 1e11, not 1e12. This avoids printing 13 significant digits in
1363 situations where only 12 of them are correct. Example problem
1364 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1365 long time.)
1366
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001367- Issue #1580: On most platforms, use a 'short' float repr: for a
1368 finite float x, repr(x) now outputs a string based on the shortest
1369 sequence of decimal digits that rounds to x. Previous behaviour was
1370 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001371 Another minor difference is that the new repr switches to
1372 exponential notation at 1e16 instead of the previous 1e17; this
1373 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001374
1375 There's a new sys attribute sys.float_repr_style, which takes
1376 the value 'short' to indicate that we're using short float repr,
1377 and 'legacy' if the short float repr isn't available for one
1378 reason or another.
1379
1380 The float repr change involves incorporating David Gay's 'perfect
1381 rounding' code into the Python core (it's in Python/dtoa.c). As a
1382 secondary consequence, all string-to-float and float-to-string
1383 conversions (including all float formatting operations) will be
1384 correctly rounded on these platforms.
1385
1386 See issue 1580 discussions for details of platforms for which
1387 this change does not apply.
1388
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001389- Issue #5759: float() didn't call __float__ on str subclasses.
1390
Georg Brandlabc38772009-04-12 15:51:51 +00001391- The string.maketrans() function is deprecated; there is a new static method
1392 maketrans() on the bytes and bytearray classes. This removes confusion about
1393 the types string.maketrans() is supposed to work with, and mirrors the
1394 methods available on the str class.
1395
R. David Murraydc6da8a2009-04-09 22:16:43 +00001396- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1397 its clarity and its speed.
1398
Matthias Klose091c7b12009-04-07 13:24:27 +00001399- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1400 to avoid compiler warnings.
1401
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001402- Issue #3739: The unicode-internal encoder now reports the number of characters
1403 consumed like any other encoder (instead of the number of bytes).

1755 to buffer arbitrary chunks of data).
1756
Raymond Hettinger35631532009-01-09 03:58:09 +00001757- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1758 instead of ints (reducing its size from 4 to 8 times thereby reducing
1759 Python's overall memory).
1760
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001761- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1762 an existing .py counterpart, override the co_filename attributes of all
1763 code objects if the original filename is obsolete (which can happen if the
1764 file has been renamed, moved, or if it is accessed through different paths).
1765 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1766

1813 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

1819 Python 2.x.
1820
Antoine Pitrou5504e892008-12-06 21:27:53 +00001821- Issue #4509: Various issues surrounding resize of bytearray objects to

1823
Georg Brandlf9734072008-12-07 15:30:06 +00001824- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1825 method on file objects with closefd=False. The file descriptor is still
1826 kept open but the file object behaves like a closed file. The ``FileIO``
1827 object also got a new readonly attribute ``closefd``.

1837 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1838 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1839 of using the replace error handler in PyUnicode_DecodeUTF8().

2118 do an explicit seek to the end of file (so that e.g. tell() returns the
