16 compiler.
17
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

217 being followed, leading to the wrong Python exception being raised.

248 witnessed in test_httpservers.
249
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000250- Issue #8524: When creating an SSL socket, the timeout value of the
251 original socket wasn't retained (instead, a socket with a positive timeout
252 would be turned into a non-blocking SSL socket).
253
Antoine Pitrouec146182010-04-24 21:30:20 +0000254- Issue #5103: SSL handshake would ignore the socket timeout and block

258 the SSL structure if necessary (as other methods already do).

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001166- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1167 (1) inf and nan strings with trailing whitespace were incorrectly
1168 rejected; (2) parsing of strings representing infinities and nans
1169 was locale aware; and (3) the interpretation of fromhex('-nan')
1170 didn't match that of float('-nan').

1273Core and Builtins
1274-----------------
1275
Mark Dickinson865e01a2009-05-07 16:37:01 +00001276- Issue #5914: Add new C API function PyOS_string_to_double, and
1277 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1278
Eric Smith741191f2009-05-06 13:08:15 +00001279- Issue #3382: float.__format__, complex.__format__, and %-formatting
1280 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1281 affects nan -> NAN and inf -> INF.
1282
Mark Hammond5a607a32009-05-06 08:04:54 +00001283- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1284 in all operations, including splitdrive, split, etc. splitunc() now issues
1285 a PendingDeprecation warning.
1286
Eric Smith63376222009-05-05 14:04:18 +00001287- Issue #5920: For float.__format__, change the behavior with the
1288 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1289 to be like 'g' but with at least one decimal point and with a
1290 default precision of 12. Previously, the behavior the same but with
1291 a default precision of 6. This more closely matches str(), and
1292 reduces surprises when adding alignment flags to the empty
1293 presentation type. This also affects the new complex.__format__ in
1294 the same way.
1295
Martin v. Löwis011e8422009-05-05 04:43:17 +00001296- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1297
R. David Murrayb18500d2009-05-04 22:59:07 +00001298- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1299 shadowed by classtype's, even if it was None. property now
1300 inserts the __doc__ into the subclass instance __dict__.
1301
Antoine Pitrou244651a2009-05-04 18:56:13 +00001302- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1303 sequences. Patch by Nick Barnes and Victor Stinner.
1304
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001305- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001306
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001307- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1308 received a new method, detach(). detach() disconnects the underlying stream
1309 from the buffer or text IO and returns it.
1310
Mark Dickinson33841c32009-05-01 15:37:04 +00001311- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1312 floats with absolute value over 1e50. Also remove length
1313 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1314 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001315
Eric Smith741191f2009-05-06 13:08:15 +00001316- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001317 format(complex(1, 2./3), '.5') now produces a sensible result.
1318
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001319- Issue #5864: Fix empty format code formatting for floats so that it
1320 never gives more than the requested number of significant digits.
1321
Eric Smith6dc46f52009-04-27 20:39:49 +00001322- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1323 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1324
Eric Smithcc32a112009-04-26 21:35:14 +00001325- Issue #5835: Deprecate PyOS_ascii_formatd.
1326
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001327- Issue #4971: Fix titlecase for characters that are their own
1328 titlecase, but not their own uppercase.
1329
Benjamin Peterson193152c2009-04-25 01:08:45 +00001330- Issue #5283: Setting __class__ in __del__ caused a segfault.
1331
Mark Dickinsonad476da2009-04-23 19:14:16 +00001332- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1333 z involves nans, infs or negative zeros.
1334
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001335- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001336
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001337- Issue #1869 (and many duplicates): make round(x, n) correctly
1338 rounded for a float x, by using the decimal <-> binary conversions
1339 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1340 consistently agrees with format(x, '.2f').
1341
Benjamin Petersonae937c02009-04-18 20:54:08 +00001342- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1343 some builtin types.
1344
Eric Smith0923d1d2009-04-16 20:16:10 +00001345- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1346
Eric Smith35e84722009-04-16 20:21:28 +00001347- Issue #5515: str.format() type 'n' combined with commas and leading
1348 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001349
1350- Implement PEP 378, Format Specifier for Thousands Separator, for
1351 floats.
1352
Mark Dickinson3370cce2009-04-17 22:40:53 +00001353- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001354 1e11, not 1e12. This avoids printing 13 significant digits in
1355 situations where only 12 of them are correct. Example problem
1356 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1357 long time.)
1358
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001359- Issue #1580: On most platforms, use a 'short' float repr: for a
1360 finite float x, repr(x) now outputs a string based on the shortest
1361 sequence of decimal digits that rounds to x. Previous behaviour was
1362 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001363 Another minor difference is that the new repr switches to
1364 exponential notation at 1e16 instead of the previous 1e17; this
1365 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001366
1367 There's a new sys attribute sys.float_repr_style, which takes
1368 the value 'short' to indicate that we're using short float repr,
1369 and 'legacy' if the short float repr isn't available for one
1370 reason or another.
1371
1372 The float repr change involves incorporating David Gay's 'perfect
1373 rounding' code into the Python core (it's in Python/dtoa.c). As a
1374 secondary consequence, all string-to-float and float-to-string
1375 conversions (including all float formatting operations) will be
1376 correctly rounded on these platforms.
1377
1378 See issue 1580 discussions for details of platforms for which
1379 this change does not apply.
1380
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001381- Issue #5759: float() didn't call __float__ on str subclasses.
1382
Georg Brandlabc38772009-04-12 15:51:51 +00001383- The string.maketrans() function is deprecated; there is a new static method
1384 maketrans() on the bytes and bytearray classes. This removes confusion about
1385 the types string.maketrans() is supposed to work with, and mirrors the
1386 methods available on the str class.
1387
R. David Murraydc6da8a2009-04-09 22:16:43 +00001388- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1389 its clarity and its speed.
1390
Matthias Klose091c7b12009-04-07 13:24:27 +00001391- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1392 to avoid compiler warnings.
1393
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001394- Issue #3739: The unicode-internal encoder now reports the number of characters
1395 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +00001473- Issue #1161031: fix readwrite select flag handling: POLLPRI now
1474 results in a handle_expt_event call, not handle_read_event, and POLLERR
1475 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1476 dispatcher now has an 'ignore_log_types' attribute for suppressing
1477 log messages, which is set to 'warning' by default.
1478
Matthias Klosea3d29e82009-04-07 13:13:10 +00001479- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for

1553 untrackable objects are not tracked by the garbage collector. This can
1554 reduce the size of collections and therefore the garbage collection overhead
1555 on long-running programs, depending on their particular use of datatypes.

Lars Gustäbel42e00912009-03-22 20:34:29 +00001625- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1626 forever on incomplete input. That caused tarfile.open() to hang when used
1627 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1628 partial bzip2 compressed data.

1745 flag to work properly. Furthermore, when specifying -u, the text stdout
1746 and stderr streams have line-by-line buffering enabled (the default being
1747 to buffer arbitrary chunks of data).
1748
Raymond Hettinger35631532009-01-09 03:58:09 +00001749- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

1805 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

1819 object also got a new readonly attribute ``closefd``.

1829 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1830 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1831 of using the replace error handler in PyUnicode_DecodeUTF8().

2389 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate

2391 skip the tests if DISPLAY is defined but can't be used.

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002394 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002395 from test support, which does the conversion.
