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

254 original socket wasn't retained (instead, a socket with a positive timeout
255 would be turned into a non-blocking SSL socket).
256
Antoine Pitrouec146182010-04-24 21:30:20 +0000257- Issue #5103: SSL handshake would ignore the socket timeout and block

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001172- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1173 (1) inf and nan strings with trailing whitespace were incorrectly
1174 rejected; (2) parsing of strings representing infinities and nans
1175 was locale aware; and (3) the interpretation of fromhex('-nan')
1176 didn't match that of float('-nan').

1279Core and Builtins
1280-----------------
1281
Mark Dickinson865e01a2009-05-07 16:37:01 +00001282- Issue #5914: Add new C API function PyOS_string_to_double, and
1283 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1284
Eric Smith741191f2009-05-06 13:08:15 +00001285- Issue #3382: float.__format__, complex.__format__, and %-formatting
1286 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1287 affects nan -> NAN and inf -> INF.
1288
Mark Hammond5a607a32009-05-06 08:04:54 +00001289- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1290 in all operations, including splitdrive, split, etc. splitunc() now issues
1291 a PendingDeprecation warning.
1292
Eric Smith63376222009-05-05 14:04:18 +00001293- Issue #5920: For float.__format__, change the behavior with the
1294 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1295 to be like 'g' but with at least one decimal point and with a
1296 default precision of 12. Previously, the behavior the same but with
1297 a default precision of 6. This more closely matches str(), and
1298 reduces surprises when adding alignment flags to the empty
1299 presentation type. This also affects the new complex.__format__ in
1300 the same way.
1301
Martin v. Löwis011e8422009-05-05 04:43:17 +00001302- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1303
R. David Murrayb18500d2009-05-04 22:59:07 +00001304- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1305 shadowed by classtype's, even if it was None. property now
1306 inserts the __doc__ into the subclass instance __dict__.
1307
Antoine Pitrou244651a2009-05-04 18:56:13 +00001308- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1309 sequences. Patch by Nick Barnes and Victor Stinner.
1310
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001311- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001312
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001313- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1314 received a new method, detach(). detach() disconnects the underlying stream
1315 from the buffer or text IO and returns it.
1316
Mark Dickinson33841c32009-05-01 15:37:04 +00001317- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1318 floats with absolute value over 1e50. Also remove length
1319 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1320 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001321
Eric Smith741191f2009-05-06 13:08:15 +00001322- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001323 format(complex(1, 2./3), '.5') now produces a sensible result.
1324
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001325- Issue #5864: Fix empty format code formatting for floats so that it
1326 never gives more than the requested number of significant digits.
1327
Eric Smith6dc46f52009-04-27 20:39:49 +00001328- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1329 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1330
Eric Smithcc32a112009-04-26 21:35:14 +00001331- Issue #5835: Deprecate PyOS_ascii_formatd.
1332
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001333- Issue #4971: Fix titlecase for characters that are their own
1334 titlecase, but not their own uppercase.
1335
Benjamin Peterson193152c2009-04-25 01:08:45 +00001336- Issue #5283: Setting __class__ in __del__ caused a segfault.
1337
Mark Dickinsonad476da2009-04-23 19:14:16 +00001338- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1339 z involves nans, infs or negative zeros.
1340
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001341- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001342
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001343- Issue #1869 (and many duplicates): make round(x, n) correctly
1344 rounded for a float x, by using the decimal <-> binary conversions
1345 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1346 consistently agrees with format(x, '.2f').
1347
Benjamin Petersonae937c02009-04-18 20:54:08 +00001348- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1349 some builtin types.
1350
Eric Smith0923d1d2009-04-16 20:16:10 +00001351- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1352
Eric Smith35e84722009-04-16 20:21:28 +00001353- Issue #5515: str.format() type 'n' combined with commas and leading
1354 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001355
1356- Implement PEP 378, Format Specifier for Thousands Separator, for
1357 floats.
1358
Mark Dickinson3370cce2009-04-17 22:40:53 +00001359- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001360 1e11, not 1e12. This avoids printing 13 significant digits in
1361 situations where only 12 of them are correct. Example problem
1362 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1363 long time.)
1364
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001365- Issue #1580: On most platforms, use a 'short' float repr: for a
1366 finite float x, repr(x) now outputs a string based on the shortest
1367 sequence of decimal digits that rounds to x. Previous behaviour was
1368 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001369 Another minor difference is that the new repr switches to
1370 exponential notation at 1e16 instead of the previous 1e17; this
1371 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001372
1373 There's a new sys attribute sys.float_repr_style, which takes
1374 the value 'short' to indicate that we're using short float repr,
1375 and 'legacy' if the short float repr isn't available for one
1376 reason or another.
1377
1378 The float repr change involves incorporating David Gay's 'perfect
1379 rounding' code into the Python core (it's in Python/dtoa.c). As a
1380 secondary consequence, all string-to-float and float-to-string
1381 conversions (including all float formatting operations) will be
1382 correctly rounded on these platforms.
1383
1384 See issue 1580 discussions for details of platforms for which
1385 this change does not apply.
1386
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001387- Issue #5759: float() didn't call __float__ on str subclasses.
1388
Georg Brandlabc38772009-04-12 15:51:51 +00001389- The string.maketrans() function is deprecated; there is a new static method
1390 maketrans() on the bytes and bytearray classes. This removes confusion about
1391 the types string.maketrans() is supposed to work with, and mirrors the
1392 methods available on the str class.
1393
R. David Murraydc6da8a2009-04-09 22:16:43 +00001394- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1395 its clarity and its speed.
1396
Matthias Klose091c7b12009-04-07 13:24:27 +00001397- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1398 to avoid compiler warnings.
1399
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001400- Issue #3739: The unicode-internal encoder now reports the number of characters
1401 consumed like any other encoder (instead of the number of bytes).

1480 results in a handle_expt_event call, not handle_read_event, and POLLERR
1481 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1482 dispatcher now has an 'ignore_log_types' attribute for suppressing
1483 log messages, which is set to 'warning' by default.

1559 untrackable objects are not tracked by the garbage collector. This can
1560 reduce the size of collections and therefore the garbage collection overhead
1561 on long-running programs, depending on their particular use of datatypes.

Lars Gustäbel42e00912009-03-22 20:34:29 +00001631- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1632 forever on incomplete input. That caused tarfile.open() to hang when used
1633 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1634 partial bzip2 compressed data.

1751 flag to work properly. Furthermore, when specifying -u, the text stdout
1752 and stderr streams have line-by-line buffering enabled (the default being
1753 to buffer arbitrary chunks of data).
1754
Raymond Hettinger35631532009-01-09 03:58:09 +00001755- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

1825 object also got a new readonly attribute ``closefd``.

1835 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1836 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1837 of using the replace error handler in PyUnicode_DecodeUTF8().

2116 do an explicit seek to the end of file (so that e.g. tell() returns the
