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

44
Victor Stinner32366b42010-04-23 12:04:53 +000045- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute

245 witnessed in test_httpservers.
246
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000247- Issue #8524: When creating an SSL socket, the timeout value of the
248 original socket wasn't retained (instead, a socket with a positive timeout
249 would be turned into a non-blocking SSL socket).
250
Antoine Pitrouec146182010-04-24 21:30:20 +0000251- Issue #5103: SSL handshake would ignore the socket timeout and block
252 indefinitely if the other end didn't respond.

1169
R. David Murray1f1b9d32009-05-27 20:56:59 +00001170- Issue #6121: pydoc now ignores leading and trailing spaces in the
1171 argument to the 'help' function.
1172
Georg Brandlfaf41492009-05-26 18:31:11 +00001173- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1174 arguments for strings with a space in them.
1175
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001176- collections.namedtuple() was not working with the following field
1177 names: cls, self, tuple, itemgetter, and property.
1178
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001179- In unittest, using a skipping decorator on a class is now equivalent to
1180 skipping every test on the class. The ClassTestSuite class has been removed.
1181
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001182- Issue #6050: Don't fail extracting a directory from a zipfile if
1183 the directory already exists.
1184
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001185- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1186 than an int, which makes some operations possible under 64-bit Linux (e.g.
1187 DN_MULTISHOT with F_NOTIFY).
1188
Antoine Pitrou716c4442009-05-23 19:04:03 +00001189- Issue #5761: Add the name of the underlying file to the repr() of various

1193 by Musashi Tamura, tests by Marcin Bachry.
1194
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001195- Issue #1983: Fix functions taking or returning a process identifier to use
1196 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1197 a process identifier type wider than the standard C integer type.
1198
R. David Murray87e20742009-05-23 01:30:26 +00001199- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1210
Antoine Pitroue4501852009-05-14 18:55:55 +00001211- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1212 library. This means, for example, that opening an UTF-16 text file in
1213 append mode doesn't add a BOM at the end of the file if the file isn't
1214 empty.
1215
R. David Murray74b89242009-05-13 17:33:03 +00001216- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1217 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1218 corrects a pydoc regression.
1219
R. David Murray99352742009-05-07 18:24:38 +00001220- Issue 5955: aifc's close method did not close the file it wrapped,
1221 now it does. This also means getfp method now returns the real fp.
1222
Benjamin Peterson932073a2009-05-23 16:14:33 +00001223Installation
1224------------
1225

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001262*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001263
1264Core and Builtins
1265-----------------
1266
Mark Dickinson865e01a2009-05-07 16:37:01 +00001267- Issue #5914: Add new C API function PyOS_string_to_double, and
1268 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1269
Eric Smith741191f2009-05-06 13:08:15 +00001270- Issue #3382: float.__format__, complex.__format__, and %-formatting
1271 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1272 affects nan -> NAN and inf -> INF.
1273
Mark Hammond5a607a32009-05-06 08:04:54 +00001274- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1275 in all operations, including splitdrive, split, etc. splitunc() now issues
1276 a PendingDeprecation warning.
1277
Eric Smith63376222009-05-05 14:04:18 +00001278- Issue #5920: For float.__format__, change the behavior with the
1279 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1280 to be like 'g' but with at least one decimal point and with a
1281 default precision of 12. Previously, the behavior the same but with
1282 a default precision of 6. This more closely matches str(), and
1283 reduces surprises when adding alignment flags to the empty
1284 presentation type. This also affects the new complex.__format__ in
1285 the same way.
1286
Martin v. Löwis011e8422009-05-05 04:43:17 +00001287- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1288
R. David Murrayb18500d2009-05-04 22:59:07 +00001289- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1290 shadowed by classtype's, even if it was None. property now
1291 inserts the __doc__ into the subclass instance __dict__.
1292
Antoine Pitrou244651a2009-05-04 18:56:13 +00001293- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1294 sequences. Patch by Nick Barnes and Victor Stinner.
1295
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001296- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001297
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001298- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1299 received a new method, detach(). detach() disconnects the underlying stream
1300 from the buffer or text IO and returns it.
1301
Mark Dickinson33841c32009-05-01 15:37:04 +00001302- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1303 floats with absolute value over 1e50. Also remove length
1304 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1305 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001306
Eric Smith741191f2009-05-06 13:08:15 +00001307- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001308 format(complex(1, 2./3), '.5') now produces a sensible result.
1309
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001310- Issue #5864: Fix empty format code formatting for floats so that it
1311 never gives more than the requested number of significant digits.
1312
Eric Smith6dc46f52009-04-27 20:39:49 +00001313- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1314 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1315
Eric Smithcc32a112009-04-26 21:35:14 +00001316- Issue #5835: Deprecate PyOS_ascii_formatd.
1317
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001318- Issue #4971: Fix titlecase for characters that are their own
1319 titlecase, but not their own uppercase.
1320
Benjamin Peterson193152c2009-04-25 01:08:45 +00001321- Issue #5283: Setting __class__ in __del__ caused a segfault.
1322
Mark Dickinsonad476da2009-04-23 19:14:16 +00001323- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1324 z involves nans, infs or negative zeros.
1325
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001326- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001327
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001328- Issue #1869 (and many duplicates): make round(x, n) correctly
1329 rounded for a float x, by using the decimal <-> binary conversions
1330 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1331 consistently agrees with format(x, '.2f').
1332
Benjamin Petersonae937c02009-04-18 20:54:08 +00001333- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1334 some builtin types.
1335
Eric Smith0923d1d2009-04-16 20:16:10 +00001336- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1337
Eric Smith35e84722009-04-16 20:21:28 +00001338- Issue #5515: str.format() type 'n' combined with commas and leading
1339 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001340
1341- Implement PEP 378, Format Specifier for Thousands Separator, for
1342 floats.
1343
Mark Dickinson3370cce2009-04-17 22:40:53 +00001344- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001345 1e11, not 1e12. This avoids printing 13 significant digits in
1346 situations where only 12 of them are correct. Example problem
1347 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1348 long time.)
1349
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001350- Issue #1580: On most platforms, use a 'short' float repr: for a
1351 finite float x, repr(x) now outputs a string based on the shortest
1352 sequence of decimal digits that rounds to x. Previous behaviour was
1353 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001354 Another minor difference is that the new repr switches to
1355 exponential notation at 1e16 instead of the previous 1e17; this
1356 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001357
1358 There's a new sys attribute sys.float_repr_style, which takes
1359 the value 'short' to indicate that we're using short float repr,
1360 and 'legacy' if the short float repr isn't available for one
1361 reason or another.
1362
1363 The float repr change involves incorporating David Gay's 'perfect
1364 rounding' code into the Python core (it's in Python/dtoa.c). As a
1365 secondary consequence, all string-to-float and float-to-string
1366 conversions (including all float formatting operations) will be
1367 correctly rounded on these platforms.
1368
1369 See issue 1580 discussions for details of platforms for which
1370 this change does not apply.
1371
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001372- Issue #5759: float() didn't call __float__ on str subclasses.
1373
Georg Brandlabc38772009-04-12 15:51:51 +00001374- The string.maketrans() function is deprecated; there is a new static method
1375 maketrans() on the bytes and bytearray classes. This removes confusion about
1376 the types string.maketrans() is supposed to work with, and mirrors the
1377 methods available on the str class.
1378
R. David Murraydc6da8a2009-04-09 22:16:43 +00001379- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1380 its clarity and its speed.
1381
Matthias Klose091c7b12009-04-07 13:24:27 +00001382- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1383 to avoid compiler warnings.
1384
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001385- Issue #3739: The unicode-internal encoder now reports the number of characters
1386 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +00001464- Issue #1161031: fix readwrite select flag handling: POLLPRI now
1465 results in a handle_expt_event call, not handle_read_event, and POLLERR
1466 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1467 dispatcher now has an 'ignore_log_types' attribute for suppressing
1468 log messages, which is set to 'warning' by default.
1469
Matthias Klosea3d29e82009-04-07 13:13:10 +00001470- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for
1471 new arguments introduced in 2.5.
1472
Walter Dörwald1b08b302009-04-25 14:13:56 +00001473- Issue #5828 (Invalid behavior of unicode.lower): Fixed bogus logic in
1474 makeunicodedata.py and regenerated the Unicode database (This fixes
1475 u'\u1d79'.lower() == '\x00').

Benjamin Peterson8f76b492009-04-03 22:22:42 +00001521- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
1522
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001523- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1524 byte, and the 'C' code only accepts a unicode character.
1525
Georg Brandl406b3d82009-04-11 21:24:37 +00001526- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1527 when hitting the recursion limit under certain circumstances.
1528
Brett Cannon0759dd62009-04-01 18:13:07 +00001529- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1530
Georg Brandlab6f2f62009-03-31 04:16:10 +00001531- Fix a segfault when running test_exceptions with coverage, caused by
1532 insufficient checks in accessors of Exception.__context__.
1533
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001534- Issue #5604: non-ASCII characters in module name passed to
1535 imp.find_module() were converted to UTF-8 while the path is
1536 converted to the default filesystem encoding, causing nonsense.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001540- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1541 the end sys.path, for compatibility with the system install of Python.
1542
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001543- Issue #4688: Add a heuristic so that tuples and dicts containing only
1544 untrackable objects are not tracked by the garbage collector. This can
1545 reduce the size of collections and therefore the garbage collection overhead
1546 on long-running programs, depending on their particular use of datatypes.
1547
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001548- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1553 2**15 for the internal representation of integers, for performance
1554 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1555 --enable-big-digits option to configure, which overrides the
1556 default. Add sys.int_info structseq to provide information about
1557 the internal format.
1558
Mark Dickinson081dfee2009-03-18 14:47:41 +00001559- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1560 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1561 and sizeof(Py_UNICODE) == 2.
1562
Eric Smith8ec90442009-03-14 12:29:34 +00001563- Issue #5237: Allow auto-numbered fields in str.format(). For

1565
Antoine Pitrou652e7072009-03-13 19:25:20 +00001566- Issue #5392: when a very low recursion limit was set, the interpreter would
1567 abort with a fatal error after the recursion limit was hit twice.
1568
Matthias Klose042f1332009-04-04 14:32:42 +00001569- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
1570 short file names.

1615
Lars Gustäbel42e00912009-03-22 20:34:29 +00001616- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1617 forever on incomplete input. That caused tarfile.open() to hang when used
1618 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1619 partial bzip2 compressed data.
1620
Mark Dickinson79f52032009-03-17 23:12:51 +00001621- Issue #2110: Add support for thousands separator and 'n' type

1724
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001725- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1726 collecting the oldest generation) so that allocating lots of objects without
1727 destroying them does not show quadratic performance. Based on a proposal by

1729 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1730
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001731- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001732 having been closed (for instance, a read() call could return some
1733 previously buffered data). Patch by Dmitry Vasiliev.
1734
Antoine Pitrou05608432009-01-09 18:53:14 +00001735- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1736 flag to work properly. Furthermore, when specifying -u, the text stdout
1737 and stderr streams have line-by-line buffering enabled (the default being
1738 to buffer arbitrary chunks of data).
1739
Raymond Hettinger35631532009-01-09 03:58:09 +00001740- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1741 instead of ints (reducing its size from 4 to 8 times thereby reducing
1742 Python's overall memory).
1743
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001744- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1745 an existing .py counterpart, override the co_filename attributes of all
1746 code objects if the original filename is obsolete (which can happen if the
1747 file has been renamed, moved, or if it is accessed through different paths).
1748 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1749
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001750- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1751 one byte. Also fixes the meaning of len() so that it returns the number of
1752 items, rather than the size in bytes.
1753

2101 do an explicit seek to the end of file (so that e.g. tell() returns the

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002379- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2380 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2381 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2382 skip the tests if DISPLAY is defined but can't be used.
2383

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002385 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002386 from test support, which does the conversion.
2387
Guilherme Polo9de29af2009-01-28 20:40:48 +00002388- Issue #5083: New 'gui' resource for regrtest.
