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'.

242 witnessed in test_httpservers.
243
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000244- Issue #8524: When creating an SSL socket, the timeout value of the
245 original socket wasn't retained (instead, a socket with a positive timeout
246 would be turned into a non-blocking SSL socket).
247
Antoine Pitrouec146182010-04-24 21:30:20 +0000248- Issue #5103: SSL handshake would ignore the socket timeout and block
249 indefinitely if the other end didn't respond.

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

1170 than an int, which makes some operations possible under 64-bit Linux (e.g.
1171 DN_MULTISHOT with F_NOTIFY).
1172
Antoine Pitrou716c4442009-05-23 19:04:03 +00001173- Issue #5761: Add the name of the underlying file to the repr() of various

1178
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001179- Issue #1983: Fix functions taking or returning a process identifier to use
1180 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1181 a process identifier type wider than the standard C integer type.
1182
R. David Murray87e20742009-05-23 01:30:26 +00001183- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1194
Antoine Pitroue4501852009-05-14 18:55:55 +00001195- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1196 library. This means, for example, that opening an UTF-16 text file in
1197 append mode doesn't add a BOM at the end of the file if the file isn't
1198 empty.
1199
R. David Murray74b89242009-05-13 17:33:03 +00001200- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1201 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1202 corrects a pydoc regression.
1203
R. David Murray99352742009-05-07 18:24:38 +00001204- Issue 5955: aifc's close method did not close the file it wrapped,
1205 now it does. This also means getfp method now returns the real fp.

1248Core and Builtins
1249-----------------
1250
Mark Dickinson865e01a2009-05-07 16:37:01 +00001251- Issue #5914: Add new C API function PyOS_string_to_double, and
1252 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1253
Eric Smith741191f2009-05-06 13:08:15 +00001254- Issue #3382: float.__format__, complex.__format__, and %-formatting
1255 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1256 affects nan -> NAN and inf -> INF.
1257
Mark Hammond5a607a32009-05-06 08:04:54 +00001258- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1259 in all operations, including splitdrive, split, etc. splitunc() now issues
1260 a PendingDeprecation warning.
1261
Eric Smith63376222009-05-05 14:04:18 +00001262- Issue #5920: For float.__format__, change the behavior with the
1263 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1264 to be like 'g' but with at least one decimal point and with a
1265 default precision of 12. Previously, the behavior the same but with
1266 a default precision of 6. This more closely matches str(), and
1267 reduces surprises when adding alignment flags to the empty
1268 presentation type. This also affects the new complex.__format__ in
1269 the same way.
1270
Martin v. Löwis011e8422009-05-05 04:43:17 +00001271- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1272
R. David Murrayb18500d2009-05-04 22:59:07 +00001273- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1274 shadowed by classtype's, even if it was None. property now
1275 inserts the __doc__ into the subclass instance __dict__.
1276
Antoine Pitrou244651a2009-05-04 18:56:13 +00001277- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1278 sequences. Patch by Nick Barnes and Victor Stinner.
1279
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001280- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001281
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001282- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1283 received a new method, detach(). detach() disconnects the underlying stream
1284 from the buffer or text IO and returns it.
1285
Mark Dickinson33841c32009-05-01 15:37:04 +00001286- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1287 floats with absolute value over 1e50. Also remove length
1288 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1289 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001290
Eric Smith741191f2009-05-06 13:08:15 +00001291- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001292 format(complex(1, 2./3), '.5') now produces a sensible result.
1293
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001294- Issue #5864: Fix empty format code formatting for floats so that it
1295 never gives more than the requested number of significant digits.
1296
Eric Smith6dc46f52009-04-27 20:39:49 +00001297- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1298 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1299
Eric Smithcc32a112009-04-26 21:35:14 +00001300- Issue #5835: Deprecate PyOS_ascii_formatd.
1301
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001302- Issue #4971: Fix titlecase for characters that are their own
1303 titlecase, but not their own uppercase.
1304
Benjamin Peterson193152c2009-04-25 01:08:45 +00001305- Issue #5283: Setting __class__ in __del__ caused a segfault.
1306
Mark Dickinsonad476da2009-04-23 19:14:16 +00001307- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1308 z involves nans, infs or negative zeros.
1309
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001310- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001311
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001312- Issue #1869 (and many duplicates): make round(x, n) correctly
1313 rounded for a float x, by using the decimal <-> binary conversions
1314 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1315 consistently agrees with format(x, '.2f').
1316
Benjamin Petersonae937c02009-04-18 20:54:08 +00001317- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1318 some builtin types.
1319
Eric Smith0923d1d2009-04-16 20:16:10 +00001320- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1321
Eric Smith35e84722009-04-16 20:21:28 +00001322- Issue #5515: str.format() type 'n' combined with commas and leading
1323 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001324
1325- Implement PEP 378, Format Specifier for Thousands Separator, for
1326 floats.
1327
Mark Dickinson3370cce2009-04-17 22:40:53 +00001328- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001329 1e11, not 1e12. This avoids printing 13 significant digits in
1330 situations where only 12 of them are correct. Example problem
1331 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1332 long time.)
1333
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001334- Issue #1580: On most platforms, use a 'short' float repr: for a
1335 finite float x, repr(x) now outputs a string based on the shortest
1336 sequence of decimal digits that rounds to x. Previous behaviour was
1337 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001338 Another minor difference is that the new repr switches to
1339 exponential notation at 1e16 instead of the previous 1e17; this
1340 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001341
1342 There's a new sys attribute sys.float_repr_style, which takes
1343 the value 'short' to indicate that we're using short float repr,
1344 and 'legacy' if the short float repr isn't available for one
1345 reason or another.
1346
1347 The float repr change involves incorporating David Gay's 'perfect
1348 rounding' code into the Python core (it's in Python/dtoa.c). As a
1349 secondary consequence, all string-to-float and float-to-string
1350 conversions (including all float formatting operations) will be
1351 correctly rounded on these platforms.
1352
1353 See issue 1580 discussions for details of platforms for which
1354 this change does not apply.
1355
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001356- Issue #5759: float() didn't call __float__ on str subclasses.
1357
Georg Brandlabc38772009-04-12 15:51:51 +00001358- The string.maketrans() function is deprecated; there is a new static method
1359 maketrans() on the bytes and bytearray classes. This removes confusion about
1360 the types string.maketrans() is supposed to work with, and mirrors the
1361 methods available on the str class.
1362
R. David Murraydc6da8a2009-04-09 22:16:43 +00001363- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1364 its clarity and its speed.
1365
Matthias Klose091c7b12009-04-07 13:24:27 +00001366- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1367 to avoid compiler warnings.
1368
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001369- Issue #3739: The unicode-internal encoder now reports the number of characters
1370 consumed like any other encoder (instead of the number of bytes).

1506
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001507- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1508 byte, and the 'C' code only accepts a unicode character.
1509
Georg Brandl406b3d82009-04-11 21:24:37 +00001510- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1511 when hitting the recursion limit under certain circumstances.
1512
Brett Cannon0759dd62009-04-01 18:13:07 +00001513- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1514
Georg Brandlab6f2f62009-03-31 04:16:10 +00001515- Fix a segfault when running test_exceptions with coverage, caused by
1516 insufficient checks in accessors of Exception.__context__.
1517
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001518- Issue #5604: non-ASCII characters in module name passed to
1519 imp.find_module() were converted to UTF-8 while the path is
1520 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00001522- Issue #5126: str.isprintable() returned False for space characters.
1523
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001524- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1525 the end sys.path, for compatibility with the system install of Python.
1526
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001527- Issue #4688: Add a heuristic so that tuples and dicts containing only
1528 untrackable objects are not tracked by the garbage collector. This can
1529 reduce the size of collections and therefore the garbage collection overhead
1530 on long-running programs, depending on their particular use of datatypes.
1531
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001532- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1544 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1545 and sizeof(Py_UNICODE) == 2.
1546
Eric Smith8ec90442009-03-14 12:29:34 +00001547- Issue #5237: Allow auto-numbered fields in str.format(). For

Antoine Pitrou652e7072009-03-13 19:25:20 +00001550- Issue #5392: when a very low recursion limit was set, the interpreter would
1551 abort with a fatal error after the recursion limit was hit twice.
1552
Matthias Klose042f1332009-04-04 14:32:42 +00001553- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1599
Lars Gustäbel42e00912009-03-22 20:34:29 +00001600- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1601 forever on incomplete input. That caused tarfile.open() to hang when used
1602 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1603 partial bzip2 compressed data.
1604
Mark Dickinson79f52032009-03-17 23:12:51 +00001605- Issue #2110: Add support for thousands separator and 'n' type

1673 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1674 evaluation loop is compiled with a new dispatch mechanism which gives
1675 speedups of up to 20%, depending on the system, on various benchmarks.

1688 type to (void *).
1689
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001690- Issue #4935: The overflow checking code in the expandtabs() method common
1691 to str, bytes and bytearray could be optimized away by the compiler, letting
1692 the interpreter segfault instead of raising an error.
1693
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001694- Issue #3720: Fix a crash when an iterator modifies its class and removes its

1717 previously buffered data). Patch by Dmitry Vasiliev.
1718
Antoine Pitrou05608432009-01-09 18:53:14 +00001719- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1720 flag to work properly. Furthermore, when specifying -u, the text stdout
1721 and stderr streams have line-by-line buffering enabled (the default being
1722 to buffer arbitrary chunks of data).
1723
Raymond Hettinger35631532009-01-09 03:58:09 +00001724- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1725 instead of ints (reducing its size from 4 to 8 times thereby reducing
1726 Python's overall memory).
1727
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001728- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1729 an existing .py counterpart, override the co_filename attributes of all
1730 code objects if the original filename is obsolete (which can happen if the
1731 file has been renamed, moved, or if it is accessed through different paths).
1732 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1733
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001734- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1735 one byte. Also fixes the meaning of len() so that it returns the number of
1736 items, rather than the size in bytes.
1737
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001738- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1739
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001740- Issue #4747: When the terminal does not use utf-8, executing a script with

1748
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001749- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1750 where the tp_hash and tp_dict slots are both NULL.
1751
Georg Brandlccc47b62008-12-28 11:44:14 +00001752- Issue #4759: None is now allowed as the first argument of

1804 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002363- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2364 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2365 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2366 skip the tests if DISPLAY is defined but can't be used.
2367
R. David Murraya21e4ca2009-03-31 23:16:50 +00002368- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002369 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002370 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00002372- Issue #5083: New 'gui' resource for regrtest.
