Anthony Baxterb4096662006-08-16 03:42:26 +0000895*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000896
897Core and builtins
898-----------------
899
Neal Norwitz24b6f202006-09-05 04:43:56 +0000900- Fix infinite recursion when subclassing long and overriding __hash__.
901
902- Fix concatenation (+=) of long strings.
903
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000904- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000905 compared equal or unequal to a string and a UnicodeDecodeError
906 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000907
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000908 Instead, the equal (==) and unequal (!=) comparison operators will
909 now issue a UnicodeWarning and interpret the two objects as
910 unequal. The UnicodeWarning can be filtered as desired using
911 the warning framework, e.g. silenced completely, turned into an
912 exception, logged, etc.
913
914 Note that compare operators other than equal and unequal will still
915 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000916
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000917- Fix segfault when doing string formatting on subclasses of long.
918
919- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
920 with new-style classes.
921
922- Fix bug related to __len__ functions returning negative values with
923 classic classes.
924
925- Patch #1538606, Fix __index__() clipping. There were some problems
926 discovered with the API and how integers that didn't fit into Py_ssize_t
927 were handled. This patch attempts to provide enough alternatives
928 to effectively use __index__.
929
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000930- Bug #1536021: __hash__ may now return long int; the final hash
931 value is obtained by invoking hash on the long int.
932
Thomas Hellerab1049c2006-08-08 17:37:00 +0000933- Bug #1536786: buffer comparison could emit a RuntimeWarning.
934
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000935- Bug #1535165: fixed a segfault in input() and raw_input() when
936 sys.stdin is closed.
937
Thomas Heller74d36f02006-08-04 18:17:40 +0000938- On Windows, the PyErr_Warn function is now exported from
939 the Python dll again.
940
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000941- Bug #1191458: tracing over for loops now produces a line event
942 on each iteration. Fixing this problem required changing the .pyc
943 magic number. This means that .pyc files generated before 2.5c1
944 will be regenerated.
945
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000946- Bug #1333982: string/number constants were inappropriately stored
947 in the byte code and co_consts even if they were not used, ie
948 immediately popped off the stack.
949
Georg Brandle9462c72006-08-04 18:03:37 +0000950- Fixed a reference-counting problem in property().
951
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000952
953Library
954-------
955
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000956- Fix a bug in the ``compiler`` package that caused invalid code to be
957 generated for generator expressions.
958
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000959- The distutils version has been changed to 2.5.0. The change to
960 keep it programmatically in sync with the Python version running
961 the code (introduced in 2.5b3) has been reverted. It will continue
962 to be maintained manually as static string literal.
963
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000964- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000965 and this cannot be converted to the required C type, an exception is
966 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000967 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000968
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000969- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000970 an exception.
971
Tim Peterscbdd3502006-09-05 01:47:53 +0000972- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000973 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000974 workarounds for clocks with low resolution, to stop the code yielding
975 duplicate UUIDs.
976
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000977- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
978 before raising SystemExit, allowing IDLE to honor quit() and exit().
979
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000980- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
981
Georg Brandl7a1af772006-08-14 21:55:28 +0000982- Patch #1536071: trace.py should now find the full module name of a
983 file correctly even on Windows.
984
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000985- logging's atexit hook now runs even if the rest of the module has
986 already been cleaned up.
987
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000988- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000989
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000990- Bug #1531405, format_exception no longer raises an exception if
991 str(exception) raised an exception.
992
Neil Schemenauer06ded092006-08-04 16:20:30 +0000993- Fix a bug in the ``compiler`` package that caused invalid code to be
994 generated for nested functions.
995
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000996

1005 raises the correct exceptions.
1006
Thomas Heller1ce433e2006-08-14 16:20:04 +00001007- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1008 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1009
Thomas Heller86720042006-08-14 11:17:48 +00001010- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1011 uses the _as_parameter_ attribute when objects are passed to foreign
1012 function calls. The ctypes version number was changed to 1.0.1.
1013
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001014- Bug #1530559, struct.pack raises TypeError where it used to convert.
1015 Passing float arguments to struct.pack when integers are expected
1016 now triggers a DeprecationWarning.
1017
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001018

1040-----
1041
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001042- Bug #1535502, build _hashlib on Windows, and use masm assembler
1043 code in OpenSSL.
1044
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001045- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001047- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001048
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001049
Tim Peters4643c2f2006-08-10 22:45:34 +00001050C API
1051-----
1052
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001053- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1054
Tim Peters4643c2f2006-08-10 22:45:34 +00001055- Bug #1069160. Internal correctness changes were made to
1056 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1057 the documentation was changed to state that the return value
1058 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001061What's New in Python 2.5 beta 3?
1062================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001063
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001064*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001065
1066Core and builtins
1067-----------------
1068
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001069- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001070 returned a long (see PEP 353).
1071
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001072- Bug #1515471: string.replace() accepts character buffers again.
1073
Neal Norwitz07aadb12006-07-30 06:55:48 +00001074- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1075 This provides the proper warning for struct.pack().
1076 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1077
Neal Norwitz0d62a062006-07-30 06:53:31 +00001078- Patch #1531113: Fix augmented assignment with yield expressions.
1079 Also fix a SystemError when trying to assign to yield expressions.
1080
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001081- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1082 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1083 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1084 excessive filesystem operations during imports.
1085
Tim Petersbc24eee2006-07-27 01:14:53 +00001086- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1087 operations on signed longs that are formally undefined by C.
1088 Unfortunately, at least one compiler now cares about that, so complicated
1089 the code to make that compiler happy again.
1090
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001091- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1092
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001093- Patch #1232023: Stop including current directory in search
1094 path on Windows.
1095
Neal Norwitze1fdb322006-07-21 05:32:28 +00001096- Fix some potential crashes found with failmalloc.
1097
Neal Norwitze7563102006-07-17 01:00:16 +00001098- Fix warnings reported by Klocwork's static analysis tool.
1099
Neal Norwitz84be93b2006-07-16 01:50:38 +00001100- Bug #1512814, Fix incorrect lineno's when code within a function
1101 had more than 255 blank lines.
1102
Georg Brandl9dceedb2006-07-12 15:31:17 +00001103- Patch #1521179: Python now accepts the standard options ``--help`` and
1104 ``--version`` as well as ``/?`` on Windows.
1105
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001106- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001107 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001108 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001109
Tim Peters112aad32006-07-19 00:03:19 +00001110- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001111 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001112 new ``sys._current_frames()`` returns a dictionary with one entry,
1113 mapping the faux "thread id" 0 to the current frame.
1114
Ronald Oussoren3075e162006-07-25 20:28:55 +00001115- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001116
Ronald Oussoren3075e162006-07-25 20:28:55 +00001117
Neal Norwitza1f10902006-07-12 07:28:29 +00001118Library
1119-------
1120
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001121- Correction of patch #1455898: In the mbcs decoder, set final=False
1122 for stream decoder, but final=True for the decode function.
1123
Georg Brandl07fec3a2006-08-01 18:49:24 +00001124- os.urandom no longer masks unrelated exceptions like SystemExit or
1125 KeyboardInterrupt.
1126
Tim Peters4643c2f2006-08-10 22:45:34 +00001127- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001128 shutil.copytree on Windows
1129
Georg Brandle34ac7c2006-07-30 11:07:23 +00001130- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1131 refers to file descriptors, not file objects.
1132
Tim Peterscbdd3502006-09-05 01:47:53 +00001133- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001134 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001135 #1513611, and probably others.
1136
Georg Brandledd9b0d2006-07-29 09:33:26 +00001137- Bug #1441397: The compiler module now recognizes module and function
1138 docstrings correctly as it did in Python 2.4.
1139
Tim Peters6f681472006-07-27 23:44:37 +00001140- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1141 lost that tests are sorted by name before being run. This rarely
1142 matters for well-written tests, but can create baffling symptoms if
1143 side effects from one test to the next affect outcomes. ``DocTestFinder``
1144 has been changed to sort the list of tests it returns.
1145
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001146- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001147 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001148
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001149- Bug #978833: Really close underlying socket in _socketobject.close.
1150
Georg Brandldb232dc2006-08-20 13:15:43 +00001151- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1152 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001153
Georg Brandlcf0c1722006-07-26 07:23:32 +00001154- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1155 to recursive calls and call it with the failing package name.
1156
Martin v. Löwis0b483032006-07-25 09:53:12 +00001157- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1158
Georg Brandlc13c34c2006-07-24 14:09:56 +00001159- Patch #1515343: Fix printing of deprecated string exceptions with a
1160 value in the traceback module.
1161
Greg Ward48fae7a2006-07-23 16:05:51 +00001162- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1163
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001164- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1165
Brett Cannoncaebe222006-07-18 04:41:36 +00001166- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1167 argument tuple. For arguments where zero is illegal, the value is forced to
1168 the minimum value that is correct. This is to support an undocumented but
1169 common way people used to fill in inconsequential information in the time
1170 tuple pre-2.4.
1171
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001172- Patch #1220874: Update the binhex module for Mach-O.
1173
Barry Warsawb110bad2006-07-21 14:51:07 +00001174- The email package has improved RFC 2231 support, specifically for
1175 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1176 (name*0=<blah>) parameter continuations. This may change the types of
1177 values returned from email.message.Message.get_param() and friends.
1178 Specifically in some cases where non-encoded continuations were used,
1179 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1180 will just return the string (since non-encoded continuations don't have
1181 charset and language parts).
1182
1183 Also, whereas % values were decoded in all parameter continuations, they are
1184 now only decoded in encoded parameter parts.
1185
Ronald Oussoren3075e162006-07-25 20:28:55 +00001186- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1187
1188- Bug #1517996: IDLE now longer shows the default Tk menu when a
1189 path browser, class browser or debugger is the frontmost window on MacOS X
1190
Barry Warsaw00decd72006-07-27 23:43:15 +00001191- Patch #1520294: Support for getset and member descriptors in types.py,
1192 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1193 of an object against these built-in types and more importantly, for getting
1194 their docstrings printed in the interactive interpreter's help() function.

1198-----------------
1199
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001200- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1201 a socket operation on a socket with a timeout, the exception will be
1202 caught correctly. Previously, the exception was not caught.
1203
Thomas Heller1393d6a2006-07-28 21:43:20 +00001204- Patch #1529514: The _ctypes extension is now compiled on more
1205 openbsd target platforms.
1206
Tim Peters9cab5932006-07-28 00:30:00 +00001207- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1208 a memory leak, affecting pickles and deep copies.
1209
Tim Petersbc24eee2006-07-27 01:14:53 +00001210- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1214
Thomas Hellerce049a02006-07-14 17:51:14 +00001215- Patch #1521817: Index range checking on ctypes arrays containing
1216 exactly one element enabled again. This allows iterating over these
1217 arrays, without the need to check the array size before.
1218
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001219- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001220 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001221 /dev/null in certain cases; this is now fixed.
1222
Thomas Heller47d7a062006-07-12 08:43:47 +00001223- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1224 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001225
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001226- Because of a misspelled preprocessor symbol, ctypes was always
1227 compiled without thread support; this is now fixed.
1228
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001229- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1230 methods now allow their database parameter to be None as the
1231 sleepycat API allows.
1232
Matt Flemingec926502006-07-28 11:27:27 +00001233- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1234 bluetooth API compared with Linux and FreeBSD.
1235
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001236Tests
1237-----
1238
1239- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1240 how long the test file should take to play. Now accepts taking 2.93 secs
1241 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1242
Georg Brandl4793aa32006-07-28 18:31:39 +00001243- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1244 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1245 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001246
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001247Build

1250- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1251
Ronald Oussoren26cad082006-08-01 21:00:57 +00001252Mac
1253---
1254
1255- PythonLauncher now works correctly when the path to the script contains
1256 characters that are treated specially by the shell (such as quotes).
1257
1258- Bug #1527397: PythonLauncher now launches scripts with the working directory
1259 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001260 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001261 expect.

1270-----------------
1271
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001272- Bug #1441486: The literal representation of -(sys.maxint - 1)
1273 again evaluates to a int object, not a long.
1274
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001275- Bug #1501934: The scope of global variables that are locally assigned
1276 using augmented assignment is now correctly determined.
1277
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001278- Bug #927248: Recursive method-wrapper objects can now safely
1279 be released.
1280
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001281- Bug #1417699: Reject locale-specific decimal point in float()
1282 and atof().
1283
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001284- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1285 omit a default "error" argument for NULL pointer. This allows
1286 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001287
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001288- Bug #1519018: 'as' is now validated properly in import statements.
1289
Neal Norwitz28746ab2006-07-09 22:14:42 +00001290- On 64 bit systems, int literals that use less than 64 bits are
1291 now ints rather than longs.
1292
Neal Norwitzed657552006-07-10 00:04:44 +00001293- Bug #1512814, Fix incorrect lineno's when code at module scope
1294 started after line 256.
1295
Tim Peters32a83612006-07-10 21:08:24 +00001296- New function ``sys._current_frames()`` returns a dict mapping thread
1297 id to topmost thread stack frame. This is for expert use, and is
1298 especially useful for debugging application deadlocks. The functionality
1299 was previously available in Fazal Majid's ``threadframe`` extension
1300 module, but it wasn't possible to do this in a wholly threadsafe way from
1301 an extension.

1318
Thomas Woutersadd19112006-07-05 11:03:49 +00001319- string.Template() now correctly handles tuple-values. Previously,
1320 multi-value tuples would raise an exception and single-value tuples would
1321 be treated as the value they contain, instead.
1322
Martin v. Löwisede77f52006-07-03 13:01:35 +00001323- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1330 degrees and radians.
1331
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001332- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001333 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001334

1336 is created.
1337
Martin v. Löwis7596e832006-07-01 15:33:37 +00001338- Bug #1513223: .close() of a _socketobj now releases the underlying
1339 socket again, which then gets closed as it becomes unreferenced.

1342 attribute values.
1343
1344- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1345 sgmllib ('[' and ']' were not accepted).
1346
Georg Brandl1be63af2006-06-28 20:23:25 +00001347- Fix a bug in the turtle module's end_fill function.
1348
Brett Cannon53ab5b72006-06-22 16:49:14 +00001349- Bug #1510580: The 'warnings' module improperly required that a Warning
1350 category be either a types.ClassType and a subclass of Warning. The proper
1351 check is just that it is a subclass with Warning as the documentation states.
1352
Georg Brandlad29e632006-06-21 17:45:17 +00001353- The compiler module now correctly compiles the new try-except-finally
1354 statement (bug #1509132).
1355
Neal Norwitz60373cd2006-06-22 06:30:50 +00001356- The wsgiref package is now installed properly on Unix.
1357
Vinay Sajip28e57612006-07-01 10:45:20 +00001358- A bug was fixed in logging.config.fileConfig() which caused a crash on
1359 shutdown when fileConfig() was called multiple times.
1360
Gerhard Häring762fbd32006-07-02 17:48:30 +00001361- The sqlite3 module did cut off data from the SQLite database at the first
1362 null character before sending it to a custom converter. This has been fixed
1363 now.
1364
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001365Extension Modules
1366-----------------
1367
Tim Peters112aad32006-07-19 00:03:19 +00001368- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1369 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1370 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001371
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001372- Assigning None to pointer type fields in ctypes structures possible
1373 overwrote the wrong fields, this is fixed now.
1374
1375- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1376 on non-Windows platforms.
1377
1378- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1379 integer or long, without range checking.
1380
1381- Patch #1517790: It is now possible to use custom objects in the ctypes
1382 foreign function argtypes sequence as long as they provide a from_param
1383 method, no longer is it required that the object is a ctypes type.
1384
1385- The '_ctypes' extension module now works when Python is configured
1386 with the --without-threads option.
1387
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001388- Bug #1513646: os.access on Windows now correctly determines write
1389 access, again.
1390
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001391- Bug #1512695: cPickle.loads could crash if it was interrupted with
1392 a KeyboardInterrupt.

1403
Tim Peters32a83612006-07-10 21:08:24 +00001404- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001405 Previously, the slight difference could cause compilation errors of the
1406 'zlib' module on systems with more than one version of zlib.
1407
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001408- The MSI compileall step was fixed to also support a TARGETDIR
1409 with spaces in it.

1427 documentation for the warnings module.
1428
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001429- Patch #1509163: MS Toolkit Compiler no longer available.

1440-----------------
1441
Georg Brandla56b9152006-06-19 06:35:54 +00001442- Patch #1507676: Error messages returned by invalid abstract object operations
1443 (such as iterating over an integer) have been improved and now include the
1444 type of the offending object to help with debugging.
1445
Brett Cannonea3912b2006-06-13 21:46:41 +00001446- Bug #992017: A classic class that defined a __coerce__() method that returned
1447 its arguments swapped would infinitely recurse and segfault the interpreter.
1448
Neal Norwitz909eb122006-06-12 02:13:21 +00001449- Fix the socket tests so they can be run concurrently.
1450
Neal Norwitzb9845e72006-06-12 02:11:18 +00001451- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001452 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001453
Brett Cannon22565aa2006-06-09 22:31:23 +00001454- Bug #532646: object.__call__() will continue looking for the __call__
1455 attribute on objects until one without one is found. This leads to recursion
1456 when you take a class and set its __call__ attribute to an instance of the
1457 class. Originally fixed for classic classes, but this fix is for new-style.
1458 Removes the infinite_rec_3 crasher.
1459
Georg Brandl24250812006-06-09 18:45:48 +00001460- The string and unicode methods startswith() and endswith() now accept
1461 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1462
Brett Cannonde3b0522006-06-08 17:00:45 +00001463- Buffer objects, at the C level, never used the char buffer
1464 implementation even when the char buffer for the wrapped object was
1465 explicitly requested (originally returned the read or write buffer).
1466 Now a TypeError is raised if the char buffer is not present but is
1467 requested.
1468
Georg Brandlddbaa662006-06-04 21:56:52 +00001469- Patch #1346214: Statements like "if 0: suite" are now again optimized
1470 away like they were in Python 2.4.
1471
Georg Brandlb7c8f542006-05-27 12:30:25 +00001472- Builtin exceptions are now full-blown new-style classes instead of
1473 instances pretending to be classes, which speeds up exception handling
1474 by about 80% in comparison to 2.5a2.
1475
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001476- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1477 Unicode 4.1.
1478
Georg Brandlf4ef1162006-05-26 18:03:31 +00001479- Patch #921466: sys.path_importer_cache is now used to cache valid and
1480 invalid file paths for the built-in import machinery which leads to
1481 fewer open calls on startup.
1482
Tim Peters696cf432006-05-24 21:10:40 +00001483- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1484 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1485 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1486 the number of input digits (it was and remains linear-time for bases
1487 2, 4, 8, 16 and 32).
1488
Tim Petersb713ec22006-05-23 18:45:30 +00001489- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1490 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1491 an integer close to ``sys.maxint``. This was repaired by patch
1492 #1335972, which also gives a nice speedup.
1493
Richard Jonescebbefc2006-05-23 18:28:17 +00001494- Patch #1337051: reduced size of frame objects.
1495
1496- PyErr_NewException now accepts a tuple of base classes as its
1497 "base" parameter.
1498
Richard Jones7c88dcc2006-05-23 10:37:38 +00001499- Patch #876206: function call speedup by retaining allocated frame
1500 objects.
1501
Georg Brandl7b90e162006-05-18 07:01:27 +00001502- Bug #1462152: file() now checks more thoroughly for invalid mode
1503 strings and removes a possible "U" before passing the mode to the
1504 C library function.
1505
Neal Norwitz1004a532006-05-15 07:17:23 +00001506- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1507
Neal Norwitz373f0a72006-05-15 07:04:36 +00001508- Bug #1487966: Fix SystemError with conditional expression in assignment
1509
Martin v. Löwis879768d2006-05-11 13:28:43 +00001510- WindowsError now has two error code attributes: errno, which carries
1511 the error values from errno.h, and winerror, which carries the error
1512 values from winerror.h. Previous versions put the winerror.h values
1513 (from GetLastError()) into the errno attribute.
1514
Martin v. Löwis77736712006-05-04 05:51:03 +00001515- Patch #1475845: Raise IndentationError for unexpected indent.
1516
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001517- Patch #1479181: split open() and file() from being aliases for each other.
1518
Tim Peters44bd9862006-06-01 13:49:23 +00001519- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1520 methods were always silently ignored by dictionaries when comparing keys.
1521 They are now passed through (except when using the C API function
1522 ``PyDict_GetItem()``, whose semantics did not change).
1523
1524- Bug #1456209: In some obscure cases it was possible for a class with a
1525 custom ``__eq__()`` method to confuse dict internals when class instances
1526 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1527 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001529Extension Modules
1530-----------------
1531
Trent Mick960a3f82006-06-28 20:30:41 +00001532- Bug #1295808: expat symbols should be namespaced in pyexpat
1533
1534- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1535
Brett Cannon6ee7d012006-06-08 16:23:04 +00001536- Change binascii.hexlify to accept a read-only buffer instead of only a char
1537 buffer and actually follow its documentation.
1538
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001539- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1540
Nick Coghlanc649ec52006-05-29 12:43:05 +00001541- Patch #1478788 (modified version): The functional extension module has
1542 been renamed to _functools and a functools Python wrapper module added.
1543 This provides a home for additional function related utilities that are
1544 not specifically about functional programming. See PEP 309.
1545
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001546- Patch #1493701: performance enhancements for struct module.
1547
Georg Brandl378d5922006-05-17 14:26:50 +00001548- Patch #1490224: time.altzone is now set correctly on Cygwin.
1549
Georg Brandl8d3342b2006-05-16 07:38:27 +00001550- Patch #1435422: zlib's compress and decompress objects now have a
1551 copy() method.
1552
Andrew MacIntyre92913322006-06-13 15:04:24 +00001553- Patch #1454481: thread stack size is now tunable at runtime for thread
1554 enabled builds on Windows and systems with Posix threads support.
1555
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001556- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1557 (up to the system limit of 32K characters).
1558
1559- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1560 As a result, these functions now raise WindowsError instead of OSError.
1561
Tim Peters7a822da2006-05-25 21:50:17 +00001562- ``time.clock()`` on Win64 should use the high-performance Windows
1563 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1564 Windows platforms).
1565
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001566- Calling Tk_Init twice is refused if the first call failed as that
1567 may deadlock.
1568
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001569- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1570 accept it without potentially using an uninitialized pointer.
1571
1572- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1573 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1574 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001575
Gregory P. Smith372b5832006-06-05 18:48:21 +00001576- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001577 [pybsddb project SF patch number 1466734]
1578
Gregory P. Smith372b5832006-06-05 18:48:21 +00001579- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1580 parameter is supplied. [SF pybsddb bug #1477863]
1581
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001582- bsddb: the __len__ method of a DB object has been fixed to return correct
1583 results. It could previously incorrectly return 0 in some cases.
1584 Fixes SF bug 1493322 (pybsddb bug 1184012).
1585
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001586- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1587 aborts the db transaction safely when a modifier callback fails.
1588 Fixes SF python patch/bug #1408584.
1589
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001590- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001591 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001592 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1593 database calls that would previously deadlock. [SF python bug #775414]
1594
Vinay Sajip28e57612006-07-01 10:45:20 +00001595- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001596
Walter Dörwald4994d952006-06-19 08:07:50 +00001597- Patch #1506645: add Python wrappers for the curses functions
1598 is_term_resized, resize_term and resizeterm.

1601-------
1602
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001603- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1604 functions.
1605
Martin v. Löwis3798da02006-06-17 18:44:27 +00001606- Patch #812986: Update turtle output even if not tracing.
1607
Vinay Sajip28e57612006-07-01 10:45:20 +00001608- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001609 Tkinter.BaseWidget.
1610
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001611- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1612
Martin v. Löwis337487e2006-06-17 09:15:14 +00001613- Patch #763580: Add name and value arguments to Tkinter variable
1614 classes.
1615
Georg Brandl83cc0d02006-06-14 08:50:03 +00001616- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1617 mime.types file for determining MIME types.
1618
Georg Brandl2605ca82006-06-14 06:08:31 +00001619- Bug #1339007: Shelf objects now don't raise an exception in their
1620 __del__ method when initialization failed.
1621
Martin v. Löwisd8251432006-06-14 05:21:04 +00001622- Patch #1455898: The MBCS codec now supports the incremental mode for
1623 double-byte encodings.
1624
Tim Peters43898b42006-06-14 04:09:25 +00001625- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1626 guarantee that adjacent triples in the return list always describe
1627 non-adjacent blocks. Previously, a pair of matching blocks could end
1628 up being described by multiple adjacent triples that formed a partition
1629 of the matching pair.
1630
Greg Ward0e0c9f42006-06-11 16:24:11 +00001631- Bug #1498146: fix optparse to handle Unicode strings in option help,
1632 description, and epilog.
1633
Greg Wardd1c797e2006-06-11 14:42:41 +00001634- Bug #1366250: minor optparse documentation error.
1635
Greg Ward7f547402006-06-11 00:40:49 +00001636- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1637 clarify docs.
1638
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001639- The wsgiref package has been added to the standard library.
1640
Nick Coghlan676725d2006-06-08 13:54:49 +00001641- The functions update_wrapper() and wraps() have been added to the functools
1642 module. These make it easier to copy relevant metadata from the original
1643 function when writing wrapper functions.
1644
Tim Petersd6a9eef2006-06-05 01:48:21 +00001645- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1646 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001647
Martin v. Löwis3f767792006-06-04 19:36:28 +00001648- Patch #1359618: Speed up charmap encoder by using a trie structure
1649 for lookup.
1650
Tim Petersd609b1a2006-06-02 23:22:51 +00001651- The functions in the ``pprint`` module now sort dictionaries by key
1652 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1653 if and only if its display required more than one line, although that
1654 wasn't documented. The new behavior increases predictability; e.g.,
1655 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1656
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001657- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1658 (thanks for J. J. Lee).
1659
Georg Brandl2b330372006-05-28 20:23:12 +00001660- Patch #1496206: improve urllib2 handling of passwords with respect to
1661 default HTTP and HTTPS ports.
1662
George Yoshidaf3c65de2006-05-28 16:39:09 +00001663- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1664
Bob Ippolito7298f272006-05-23 18:43:47 +00001665- Patch #1281707: speed up gzip.readline.
1666
Georg Brandlb89316f2006-05-17 15:51:16 +00001667- Patch #1180296: Two new functions were added to the locale module:
1668 format_string() to get the effect of "format % items" but locale-aware,
1669 and currency() to format a monetary number with currency sign.
1670
Georg Brandle3a25832006-05-17 14:56:04 +00001671- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1672 and several features added, such as speed and geometry control.
1673
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001674- Patch #1488881: add support for external file objects in bz2 compressed
1675 tarfiles.
1676
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001677- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1678 stdout arguments, making it possible to redirect input and output
1679 for remote debugging.
1680
1681- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1682 a couple of issues, notably handling of long file names using the
1683 GNU LONGNAME extension.
1684
1685- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1686 new flag when ``name`` is already the name of an option flag.
1687
1688- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1689 package.
1690
1691- Patch #1472854: make the rlcompleter.Completer class usable on non-
1692 UNIX platforms.
1693
1694- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1695
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001696- Bug #1472827: correctly escape newlines and tabs in attribute values in
1697 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001727What's New in Python 2.5 alpha 2?

1729
1730*Release date: 27-APR-2006*
1731
1732Core and builtins
1733-----------------
1734
Thomas Heller1b046642006-04-18 18:51:06 +00001735- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1736 by converting these apis from macros into exported functions again:
1737
1738 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1739 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1740 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1741 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1742 PyRun_String Py_CompileString
1743
Martin v. Löwis45294a92006-04-18 06:24:08 +00001744- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1745
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001746- All uses of PyStructSequence_InitType have been changed to initialize
1747 the type objects only once, even if the interpreter is initialized
1748 multiple times.
1749
Neal Norwitz61546162006-04-14 05:20:28 +00001750- Bug #1454485, array.array('u') could crash the interpreter. This was
1751 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1752 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1753
1754- Py_UNICODE is unsigned. It was always documented as unsigned, but
1755 due to a bug had a signed value in previous versions.
1756
Tim Peters3a5e8b12006-04-11 01:44:07 +00001757- Patch #837242: ``id()`` of any Python object always gives a positive
1758 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1759 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001760 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001761 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001762
Tim Peters3a5e8b12006-04-11 01:44:07 +00001763 def __hash__(self):
1764 return id(self) # WRONG
1765
1766 because a hash result must be a (short) Python int but it was always
1767 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001768 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001769 was always usable as a hash value before this patch. That's no longer
1770 necessarily so.
1771
1772- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001773 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001774 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001775 #1454844)
1776
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001777- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1778 involving generators that have paused outside of any ``try`` or ``with``
1779 blocks. (In 2.5a1, a paused generator that was part of a reference
1780 cycle could not be garbage collected, regardless of whether it was
1781 paused in a ``try`` or ``with`` block.)

1795 the cachesize parameter.
1796
1797- Bug #1149413: bsddb.*open() no longer raises an exception when using
1798 a temporary db (file=None) with the 'n' flag to truncate on open.
1799
1800- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1801 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001802
Armin Rigoa9017c32006-04-19 11:50:27 +00001803- Patch #1062014: AF_UNIX sockets under Linux have a special

1810 of the process using the returncode attribute, instead of
1811 abusing errno.
1812
Tim Peters711bf302006-04-25 03:31:36 +00001813- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1814 a doctest to be skipped (the code is not run, and the expected output
1815 or exception is ignored).
1816
Nick Coghlanda2268f2006-04-24 04:37:15 +00001817- Fixed contextlib.nested to cope with exceptions being raised and
1818 caught inside exit handlers.
1819
Greg Wardab05edc2006-04-23 03:47:58 +00001820- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1821 hex, octal, or binary; add ``append_const`` action; keep going if
1822 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1823 added ``epilog`` for better help generation).
1824
Tim Peters21fbd572006-04-21 21:18:10 +00001825- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1826 called from a thread spawned as a side effect of importing a module.
1827
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001828- The pydoc module now supports documenting packages contained in
1829 .zip or .egg files.
1830
1831- The pkgutil module now has several new utility functions, such
1832 as ``walk_packages()`` to support working with packages that are either
1833 in the filesystem or zip files.
1834
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001835- The mailbox module can now modify and delete messages from
1836 mailboxes, in addition to simply reading them. Thanks to Gregory
1837 K. Johnson for writing the code, and to the 2005 Google Summer of
1838 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001839
Tim Petersc7605f22006-04-17 21:12:33 +00001840- The ``__del__`` method of class ``local`` in module ``_threading_local``

Anthony Baxtere29002c2006-04-12 12:07:31 +00001849- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1850 Windows. Bug #1469163.
1851
Phillip J. Eby47032112006-04-11 01:07:43 +00001852- The warnings, linecache, inspect, traceback, site, and doctest modules
1853 were updated to work correctly with modules imported from zipfiles or
1854 via other PEP 302 __loader__ objects.

1862
Skip Montanaro262fb922006-04-21 02:31:07 +00001863- The pstats.Stats class accepts an optional stream keyword argument to
1864 direct output to an alternate file-like object.
1865
Anthony Baxter51bcb682006-04-05 14:51:42 +00001866Build
1867-----
1868
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001869- The Makefile now has a reindent target, which runs reindent.py on
1870 the library.
1871
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001872- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001875
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001876- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1877 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001878 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001879 CXX from --with-cxx-main, see description in README.
1880
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001881- Patch #1429775: Link extension modules with the shared libpython.
1882
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001883- Fixed a libffi build problem on MIPS systems.
1884
Tim Peters8931ff12006-05-13 23:28:20 +00001885- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1886 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1887 and "%zu" for unsigned integers of type ``size_t``.
1888
Anthony Baxter51bcb682006-04-05 14:51:42 +00001889Tests
1890-----
1891
Nick Coghlanda2268f2006-04-24 04:37:15 +00001892- test_contextlib now checks contextlib.nested can cope with exceptions
1893 being raised and caught inside exit handlers.
1894
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001895- test_cmd_line now checks operation of the -m and -c command switches
1896
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001897- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1898 it separately and by hand. It also wasn't cleaning up its changes to
1899 the current Decimal context.
1900
Thomas Woutersabd08882006-04-26 15:53:30 +00001901- regrtest.py now has a -M option to run tests that test the new limits of
1902 containers, on 64-bit architectures. Running these tests is only sensible
1903 on 64-bit machines with more than two gigabytes of memory. The argument
1904 passed is the maximum amount of memory for the tests to use.
1905
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001906Tools

1913-------------
1914
Tim Petersb06d28c2006-05-12 01:57:59 +00001915- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1916
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001917- PEP 343: Added Context Types section to the library reference
1918 and attempted to bring other PEP 343 related documentation into
1919 line with the implementation and/or python-dev discussions.
1920
Tim Peters8dc73d22006-04-24 02:03:16 +00001921- Bug #1337990: clarified that ``doctest`` does not support examples
1922 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001925What's New in Python 2.5 alpha 1?
1926=================================
1927
Anthony Baxterebed3f62006-04-03 15:03:44 +00001928*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001929
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001930Core and builtins
1931-----------------
1932
Nick Coghlan43832302006-04-23 17:04:07 +00001933- PEP 338: -m command line switch now delegates to runpy.run_module
1934 allowing it to support modules in packages and zipfiles
1935
Martin v. Löwisc661b882006-04-20 04:54:23 +00001936- On Windows, .DLL is not an accepted file name extension for
1937 extension modules anymore; extensions are only found if they
1938 end in .PYD.
1939
Martin v. Löwisea62d252006-04-03 10:56:49 +00001940- Bug #1421664: sys.stderr.encoding is now set to the same value as
1941 sys.stdout.encoding.
1942
Neal Norwitz92e212f2006-04-03 04:48:37 +00001943- __import__ accepts keyword arguments.
1944
Georg Brandlccadf842006-03-31 18:54:53 +00001945- Patch #1460496: round() now accepts keyword arguments.
1946
Anthony Baxter262c00a2006-03-30 10:53:17 +00001947- Fixed bug #1459029 - unicode reprs were double-escaped.
1948
Hye-Shik Changd478f342006-03-23 12:32:36 +00001949- Patch #1396919: The system scope threads are reenabled on FreeBSD
1950 5.4 and later versions.
1951
Neal Norwitze98ccf62006-03-23 05:39:47 +00001952- Bug #1115379: Compiling a Unicode string with an encoding declaration
1953 now gives a SyntaxError.
1954
Georg Brandlabd1ff82006-03-18 07:59:59 +00001955- Previously, Python code had no easy way to access the contents of a
1956 cell object. Now, a ``cell_contents`` attribute has been added
1957 (closes patch #1170323).
1958
Tim Peterscf79aac2006-03-16 01:14:46 +00001959- Patch #1123430: Python's small-object allocator now returns an arena to
1960 the system ``free()`` when all memory within an arena becomes unused
1961 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1962 freed. Some applications will see a drop in virtual memory size now,
1963 especially long-running applications that, from time to time, temporarily
1964 use a large number of small objects. Note that when Python returns an
1965 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001966 platform C library will in turn return that memory to the operating system.
1967 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001968 appears to be effective at least on Microsoft C and gcc-based systems.
1969 Thanks to Evan Jones for hard work and patience.
1970
Georg Brandl533ff6f2006-03-08 18:09:27 +00001971- Patch #1434038: property() now uses the getter's docstring if there is
1972 no "doc" argument given. This makes it possible to legitimately use
1973 property() as a decorator to produce a read-only property.
1974
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001975- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1976 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1977 of requiring an int or long in slicing and a few other contexts, enabling
1978 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1979
Neal Norwitz995acdf2006-03-07 05:01:00 +00001980- Fixed various bugs reported by Coverity's Prevent tool.
1981
Brett Cannonbf364092006-03-01 04:25:17 +00001982- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1983 new exception base class, BaseException, which has a new message attribute.
1984 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1985 Raising a string exception now raises a DeprecationWarning.
1986
Thomas Woutersfb609f42006-02-28 16:37:25 +00001987- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1988 explicitly relative, using 'from .module import name' to mean 'from the same
1989 package as this module is in. Imports without dots still default to the
1990 old relative-then-absolute, unless 'from __future__ import
1991 absolute_import' is used.
1992
Brett Cannona7446e32006-02-27 23:39:10 +00001993- Properly check if 'warnings' raises an exception (usually when a filter set
1994 to "error" is triggered) when raising a warning for raising string
1995 exceptions.
1996
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001997- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001998 The name was removed from Include/code.h.
1999
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002000- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002001
Guido van Rossum1968ad32006-02-25 22:38:04 +00002002- Patch 1433928:
2003 - The copy module now "copies" function objects (as atomic objects).
2004 - dict.__getitem__ now looks for a __missing__ hook before raising
2005 KeyError.
2006
Tim Peters84ef21c2006-02-28 20:39:06 +00002007- PEP 343: with statement implemented. Needs ``from __future__ import
2008 with_statement``. Use of 'with' as a variable will generate a warning.
2009 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002010 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002011 The following objects have __context__ methods:
2012 - The built-in file type.
2013 - The thread.LockType type.
2014 - The following types defined by the threading module:
2015 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2016 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002017
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002018- Fix the encodings package codec search function to only search
2019 inside its own package. Fixes problem reported in patch #1433198.
2020
2021 Note: Codec packages should implement and register their own
2022 codec search function. PEP 100 has the details.
2023
Tim Peters9ea89d22006-06-04 03:26:02 +00002024- PEP 353: Using ``Py_ssize_t`` as the index type.
2025
2026- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2027 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2028 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2029 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2030 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002031
Neal Norwitzfc76d632006-01-10 06:03:13 +00002032- Patch #1400181, fix unicode string formatting to not use the locale.
2033 This is how string objects work. u'%f' could use , instead of .
2034 for the decimal point. Now both strings and unicode always use periods.
2035
Neal Norwitz671b9e32006-01-09 07:07:12 +00002036- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2037 configure would break checking curses.h.
2038
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002039- Bug #959576: The pwd module is now builtin. This allows Python to be
2040 built on UNIX platforms without $HOME set.
2041
Neal Norwitzc10978f2005-12-19 06:07:16 +00002042- Bug #1072182, fix some potential problems if characters are signed.
2043
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002044- Bug #889500, fix line number on SyntaxWarning for global declarations.
2045
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002046- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2047
Neal Norwitze7214a12005-12-18 05:03:17 +00002048- Support for converting hex strings to floats no longer works.
2049 This was not portable. float('0x3') now raises a ValueError.
2050
Barry Warsaw2a38a862005-12-18 01:27:35 +00002051- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002052 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002053 is now displayed in interactive prompt banner.
2054
Georg Brandlfa166682005-12-17 21:45:17 +00002055- Implementation of PEP 341 - Unification of try/except and try/finally.
2056 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002057 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002058
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002059- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2060 now encodes backslash correctly.
2061
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002062- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2063
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002064- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002065 and long longs.
2066
Neal Norwitz67715f02005-11-09 06:59:35 +00002067- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002068 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002069 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002070
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002071- Replaced most Unicode charmap codecs with new ones using the
2072 new Unicode translate string feature in the builtin charmap
2073 codec; the codecs were created from the mapping tables available
2074 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2075 encodings now include a mapping for the Apple logo)
2076
Tim Peterse3547fd2005-12-16 23:13:57 +00002077- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002078
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002079- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002080
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002081- A new AST parser implementation was completed. The abstract
2082 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002083 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002084
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002085- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002086 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2087
Neal Norwitz708e51a2005-10-03 04:48:15 +00002088- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2089
Neal Norwitz11bd1192005-10-03 00:54:56 +00002090- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2091 Provide a warning when a directory is passed on the command line.
2092
Neal Norwitz40d37812005-10-02 01:48:49 +00002093- Fix segfault with invalid coding.
2094
2095- SF bug #772896: unknown encoding results in MemoryError.
2096
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002097- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002098 supported a __len__() method which evaluated to False when the iterator
2099 was empty.
2100
Guido van Rossum630db602005-09-20 18:49:54 +00002101- On 64-bit platforms, when __len__() returns a value that cannot be
2102 represented as a C int, raise OverflowError.
2103
Skip Montanarof8948ca2005-09-19 03:54:46 +00002104- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002105 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002106
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002107- SF bug #893549: parsing keyword arguments was broken with a few format
2108 codes.
2109
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002110- Changes donated by Elemental Security to make it work on AIX 5.3
2111 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2112 bug #105470: test_pwd fails on 64bit system (Opteron).
2113
Guido van Rossum539c6622005-09-14 17:49:54 +00002114- Changes donated by Elemental Security to make it work on HP-UX 11 on
2115 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2116
Georg Brandl4550b8d2005-08-26 06:43:52 +00002117- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002118 (fixes bug #1119418).
2119
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002120- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2121
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002122- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2123 exceptions that cause a function to exit.
2124
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002125- The implementation of set() and frozenset() was revised to use its
2126 own internal data structure. Memory consumption is reduced by 1/3
2127 and there are modest speed-ups as well. The API is unchanged.
2128
Tim Petersde7990b2005-07-17 23:45:23 +00002129- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2130
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002131- SF bug #1229429: PyObject_CallMethod failed to decrement some
2132 reference counts in some error exit cases.
2133
Tim Petersecc6e6a2005-07-10 22:30:55 +00002134- SF bug #1185883: Python's small-object memory allocator took over
2135 a block managed by the platform C library whenever a realloc specified
2136 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002137 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002138 portable way to copy data from the C-managed block into Python's
2139 small-object space without risking a memory fault. Python's small-object
2140 realloc now leaves such blocks under the control of the platform C
2141 realloc.
2142
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002143- SF bug #1232517: An overflow error was not detected properly when
2144 attempting to convert a large float to an int in os.utime().
2145
Raymond Hettinger3296e692005-06-29 23:29:56 +00002146- SF bug #1224347: hex longs now print with lowercase letters just
2147 like their int counterparts.
2148
Michael W. Hudson188d4362005-06-20 16:52:57 +00002149- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2150 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2151 interpreter states; back out that fix and do a better job (see
2152 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2153 for a longer write-up of the problem).
2154
Michael W. Hudsondf888462005-06-03 14:41:55 +00002155- SF patch #1180995: marshal now uses a binary format by default when
2156 serializing floats.
2157
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002158- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2159 the routines that promise to produce IEEE 754 binary representations
2160 of floats now simply copy bytes around.
2161
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002162- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2163 278.
2164
Brett Cannonc3647ac2005-04-26 03:45:26 +00002165- patch #1109424: int, long, float, complex, and unicode now check for the
2166 proper magic slot for type conversions when subclassed. Previously the
2167 magic slot was ignored during conversion. Semantics now match the way
2168 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002169 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002170 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002171 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002172
Barry Warsawc8d907c2005-04-19 23:43:40 +00002173- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2174 NULL, now raise an AttributeError when attempting to set or delete the
2175 attribute. Previously a TypeError was raised, but this was inconsistent
2176 with the equivalent pure-Python implementation.
2177
Michael W. Hudson774479c2005-04-18 08:46:17 +00002178- It is now safe to call PyGILState_Release() before
2179 PyEval_InitThreads() (note that if there is reason to believe there
2180 are multiple threads around you still must call PyEval_InitThreads()
2181 before using the Python API; this fix is for extension modules that
2182 have no way of knowing if Python is multi-threaded yet).
2183
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002184- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2185 disabled caused a crash.
2186
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002187- Bug #1165306: instancemethod_new allowed the creation of a method
2188 with im_class == im_self == NULL, which caused a crash when called.
2189
Tim Petersecc6e6a2005-07-10 22:30:55 +00002190- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002191 fixes the crash seen in bug #1165761
2192
Raymond Hettinger96229b12005-03-11 06:49:40 +00002193- Added two new builtins, any() and all().
2194
Brett Cannon409d8f22005-03-05 06:47:57 +00002195- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002196 (e.g., ``class C(): pass`` is no longer a syntax error).
2197 Patch #1176012 added support to the 'parser' module and 'compiler' package
2198 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002199
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002200- Patch #1115086: Support PY_LONGLONG in structmember.
2201
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002202- Bug #1155938: new style classes did not check that __init__() was
2203 returning None.
2204
Tim Petersecc6e6a2005-07-10 22:30:55 +00002205- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002206 ('\') with a specific error message.
2207
Martin v. Löwisff232d72005-03-03 09:24:38 +00002208- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2209
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002210- Bug #1124295: the __name__ attribute of file objects was
2211 inadvertently made inaccessible in restricted mode.
2212
Tim Petersecc6e6a2005-07-10 22:30:55 +00002213- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002214 an ferror() call.
2215
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002216- min() and max() now support key= arguments with the same meaning as in
2217 list.sort().
2218
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002219- The peephole optimizer now performs simple constant folding in expressions:
2220 (2+3) --> (5).
2221
Raymond Hettingera422c342005-01-11 03:03:27 +00002222- set and frozenset objects can now be marshalled. SF #1098985.
2223
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002224- Bug #1077106: Poor argument checking could cause memory corruption
2225 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002226
Jeremy Hyltonab630502005-02-04 18:44:06 +00002227- The parser did not complain about future statements in illegal
2228 positions. It once again reports a syntax error if a future
2229 statement occurs after anything other than a doc string.
2230
Neil Schemenauercf52c072005-08-12 17:34:58 +00002231- Change the %s format specifier for str objects so that it returns a
2232 unicode instance if the argument is not an instance of basestring and
2233 calling __str__ on the argument returns a unicode instance.
2234
Tim Petersf4e69282006-02-27 17:15:31 +00002235- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2236 current thread state when the auto-GIL-state machinery knows about
2237 it (since the thread state is being deleted, continuing to remember it
2238 can't help, but can hurt if another thread happens to get created with
2239 the same thread id).
2240
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002241Extension Modules
2242-----------------
2243
Georg Brandl43f08a82006-03-31 18:01:16 +00002244- Patch #1380952: fix SSL objects timing out on consecutive read()s

Georg Brandlbc45a3f2006-03-17 19:17:34 +00002253
Neal Norwitz10be10c2006-03-16 06:50:13 +00002254- Everything under lib-old was removed. This includes the following modules:
2255 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002256 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002257 util, whatsound, whrandom, zmod
2258
2259- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2260
2261- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002262 is deprecated. The undocumented re.engine variable no longer exists.
2263
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002264- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2265 SS2 (single-shift 2) escape sequences correctly.
2266
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002267- The unicodedata module was updated to the 4.1 version of the Unicode
2268 database. The 3.2 version is still available as unicodedata.db_3_2_0
2269 for applications that require this specific version (such as IDNA).
2270
Neal Norwitzb62c4332006-03-04 18:35:47 +00002271- The timing module is no longer built by default. It was deprecated
2272 in PEP 4 in Python 2.0 or earlier.
2273
Guido van Rossum1968ad32006-02-25 22:38:04 +00002274- Patch 1433928: Added a new type, defaultdict, to the collections module.
2275 This uses the new __missing__ hook behavior added to dict (see above).
2276
Georg Brandldbd83392006-02-20 09:42:33 +00002277- Bug #854823: socketmodule now builds on Sun platforms even when
2278 INET_ADDRSTRLEN is not defined.
2279
Georg Brandlf4f44152006-02-18 22:29:33 +00002280- Patch #1393157: os.startfile() now has an optional argument to specify
2281 a "command verb" to invoke on the file.
2282
Neal Norwitz082b2df2006-02-07 07:04:46 +00002283- Bug #876637, prevent stack corruption when socket descriptor
2284 is larger than FD_SETSIZE.
2285
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002286- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2287 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2288 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2289
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002290- Patch #1422385: The nis module now supports access to domains other
2291 than the system default domain.
2292
Martin v. Löwis14694662006-02-03 12:54:16 +00002293- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2294 are reported, the limit on path name lengths is removed, and stat reports
2295 WindowsError now (instead of OSError).
2296
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002297- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2298
Neal Norwitz62a21122006-01-25 05:21:55 +00002299- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
2300 before the env.
2301
Martin v. Löwis11017b12006-01-14 18:12:57 +00002302- Patch #1103116: Basic AF_NETLINK support.
2303
Neal Norwitz3b4fff82006-01-11 08:54:45 +00002304- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)
2305
Neal Norwitz88bbd732006-01-10 07:05:44 +00002306- Bug #1400822, _curses over{lay,write} doesn't work when passing 6 ints.
2307 Also fix ungetmouse() which did not accept arguments properly.
2308 The code now conforms to the documented signature.
2309
Neal Norwitz5e3d8622006-01-09 06:24:35 +00002310- Bug #1400115, Fix segfault when calling curses.panel.userptr()
2311 without prior setting of the userptr.
2312
Neal Norwitz40c6b472006-01-05 05:43:35 +00002313- Fix 64-bit problems in bsddb.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002431- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2432 been renamed to have only a single underscore prefix. This was done to
2433 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002434
Nick Coghlan43832302006-04-23 17:04:07 +00002435- PEP 338: new module runpy defines a run_module function to support
2436 executing modules which provide access to source code or a code object
2437 via the PEP 302 import mechanisms.
2438
Anthony Baxter93f5b932006-04-03 08:05:07 +00002439- The email module's parsedate_tz function now sets the daylight savings
2440 flag to -1 (unknown) since it can't tell from the date whether it should

2447 in attribute values.
2448
Anthony Baxterc51ee692006-04-01 00:57:31 +00002449- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002450 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002451 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002452 module will not be built.
2453
Tim Petersc17976e2006-04-01 00:26:53 +00002454- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2455 aren't officially supported here, and trying to use them will probably
2456 raise an exception some day. But dicts have been allowed, and "mostly
2457 worked", so support for them won't go away without warning.
2458
Georg Brandl338ef7d2006-03-31 18:42:16 +00002459- Bug #1445068: getpass.getpass() can now be given an explicit stream
2460 argument to specify where to write the prompt.
2461

Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002470- Queue.Queue objects now support .task_done() and .join() methods
2471 to make it easier to monitor when daemon threads have completed
2472 processing all enqueued tasks. Patch #1455676.
2473

2477
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002478- email 4.0 package now integrated. This is largely the same as the email 3.0
2479 package that was included in Python 2.3, except that PEP 8 module names are
2480 now used (e.g. mail.message instead of email.Message). The MIME classes
2481 have been moved to a subpackage (e.g. email.mime.text instead of
2482 email.MIMEText). The old names are still supported for now. Several
2483 deprecated Message methods have been removed and lots of bugs have been
2484 fixed. More details can be found in the email package documentation.
2485
Walter Dörwald40108c92006-03-27 08:15:44 +00002486- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2487 (a subclass of tuple) that provides incremental decoders and encoders
2488 (a way to use stateful codecs without the stream API). Python functions
2489 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2490 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2491 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002492
Walter Dörwald067db482006-03-15 22:17:27 +00002493- Patch #1359365: Calling next() on a closed StringIO.String object raises
2494 a ValueError instead of a StopIteration now (like file and cString.String do).
2495 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2496 called before (like file and StringIO.StringIO do).

Martin v. Löwis3e865952006-01-24 15:51:21 +00002546 specifications, raises IOErrors when proxies for unsupported protocols
2547 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002570 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2571 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2572 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2573 Ronald L. Rivest offered this advice for Python:
2574
2575 "The consensus of researchers in this area (at least as
2576 expressed at the NIST Hash Function Workshop 10/31/05),
2577 is that SHA-256 is a good choice for the time being, but
2578 that research should continue, and other alternatives may
2579 arise from this research. The larger SHA's also seem OK."

2634 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002635 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002636

2674 Bug #1224621.
2675
Raymond Hettinger68c04532005-06-10 11:05:19 +00002676- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002677 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002678 the generate_tokens() function now accepts a callable argument that
2679 terminates by raising StopIteration.
2680
Georg Brandl9166e1a2005-06-04 09:20:03 +00002681- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2689 class at all.
2690
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002691- distutils.commands.upload was added to support uploading distribution

2693
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002694- distutils.commands.register now encodes the data as UTF-8 before posting
2695 them to PyPI.
2696
Raymond Hettinger267b8682005-03-27 10:47:39 +00002697- decimal operator and comparison methods now return NotImplemented
2698 instead of raising a TypeError when interacting with other types. This
2699 allows other classes to implement __radd__ style methods and have them
2700 work as expected.
2701
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002702- Bug #1163325: Decimal infinities failed to hash. Attempting to
2703 hash a NaN raised an InvalidOperation instead of a TypeError.
2704
Tim Petersecc6e6a2005-07-10 22:30:55 +00002705- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2739
Guido van Rossumd0641422005-02-03 15:01:24 +00002740- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2741 disables recursive traversal through instance attributes, which can
2742 be exploited in various ways.
2743
Tim Peterse3547fd2005-12-16 23:13:57 +00002744- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002745 flags on the HTTP listening socket.
2746
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002747- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2748 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2749
Fred Drakefbdeaad2006-07-29 16:56:15 +00002750- Patches #893642, #1039083: add allow_none, encoding arguments to
2751 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002752
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002753- Bug #1110478: Revert os.environ.update to do putenv again.
2754
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002755- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2756
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002757- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2758
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002759- Enhancements to the csv module:
2760
2761 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002762 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002763 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002764 + Dialect parameter parsing has been re-implemented to improve error
2765 reporting.
2766 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2767 dictates.
2768 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002769 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002770 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002771 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2772 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002773 + reader now allows \r characters to be quoted (previously it only allowed
2774 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002775 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002776 + Dialect classes passed to the module are no longer instantiated by
2777 the module before being parsed (the former validation scheme required
2778 this, but the mechanism was unreliable).
2779 + The dialect registry now contains instances of the internal
2780 C-coded dialect type, rather than references to python objects.
2781 + the internal c-coded dialect type is now immutable.
2782 + register_dialect now accepts the same keyword dialect specifications
2783 as the reader and writer, allowing the user to register dialects
2784 without first creating a dialect class.
2785 + a configurable limit to the size of parsed fields has been added -
2786 previously, an unmatched quote character could result in the entire
2787 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002788 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002789 the parser field size limit (returning the former limit). The initial
2790 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002791 + A line_num attribute has been added to the reader object, which tracks
2792 the number of lines read from the source iterator. This is not
2793 the same as the number of records returned, as records can span
2794 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002795 + reader and writer objects were not being registered with the cyclic-GC.
2796 This has been fixed.
2797
Brett Cannone6539c42005-01-08 02:43:53 +00002798- _DummyThread objects in the threading module now delete self.__block that is
2799 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2800 lock primitives tend to be limited in number and thus should not be wasted on
2801 a _DummyThread object. Fixes bug #1089632.
2802
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002803- The imghdr module now detects Exif files.
2804
Raymond Hettinger6065d322004-12-20 23:51:53 +00002805- StringIO.truncate() now correctly adjusts the size attribute.
2806 (Bug #951915).
2807
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002808- locale.py now uses an updated locale alias table (built using
2809 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2810 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002811 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002812
Raymond Hettinger3557f422004-12-07 12:02:02 +00002813- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2814
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002815- the pickle module no longer accepts the deprecated None option in the
2816 args tuple returned by __reduce__().
2817
Brett Cannon84667c02004-12-07 03:25:18 +00002818- optparse now optionally imports gettext. This allows its use in setup.py.
2819
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002820- the pickle module no longer uses the deprecated bin parameter.
2821
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002822- the shelve module no longer uses the deprecated binary parameter.
2823
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002824- the pstats module no longer uses the deprecated ignore() method.
2825
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002826- the filecmp module no longer uses the deprecated use_statcache argument.
2827
Raymond Hettinger664347b2004-12-04 21:21:53 +00002828- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2829 extended or overridden by subclasses. Formerly, the subclassed method would
2830 be ignored by the rest of the module. (Bug #1078905).
2831
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002832- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002833 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002834
Walter Dörwald36733692004-12-22 12:50:50 +00002835- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2836 once when a size argument is given. This prevents a buffer overflow in the
2837 tokenizer with very long source lines.

Barry Warsaw538561e2006-01-01 21:48:54 +00002839- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2840 immediately after creating the object, without any intervening
2841 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002842
Skip Montanaro05885812005-01-16 20:48:27 +00002843- The reconvert.quote function can now emit triple-quoted strings. The
2844 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002845
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002846- ``UserString.MutableString`` now supports negative indices in
2847 ``__setitem__`` and ``__delitem__``
2848
Greg Ward40407942005-03-05 02:53:17 +00002849- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2850 correctly.
2851
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002852- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2853 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2854 character even if the user has passed a size parameter to get a proper
2855 line ending. Remove the special handling of a "\r\n" that has been split
2856 between two lines.
2857
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002858- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2859 about illegal code points. The codec now supports PEP 293 style error
2860 handlers.
2861
Walter Dörwald78a78b02005-09-01 12:04:29 +00002862- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002863 from the input stream, so that the output is a byte string in the correct
2864 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002865
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002866- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2867 considering it exactly like a '*'.
2868
Walter Dörwald007f8df2005-10-09 19:42:27 +00002869- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2870 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002871
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002872- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2873
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002874- Patch #1413711: Certain patterns of differences were making difflib
2875 touch the recursion limit.
2876
Walter Dörwald58917a62006-03-31 15:26:22 +00002877- Bug #947906: An object oriented interface has been added to the calendar
2878 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002879 called as a script (e.g. via ``python -mcalendar``). Localized month and
2880 weekday names can be ouput (even if an exotic encoding is used) using
2881 special classes that use unicode.

2885
Neal Norwitz602d3392006-03-31 08:21:40 +00002886- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2887 by using -mieee gcc option.
2888

2890
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002891- Build support for Win64-AMD64 was added.
2892
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002893- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2894
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002895- Patch #881820: look for openpty and forkpty also in libbsd.
2896
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002897- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2898 The zlib module is now builtin on Windows.
2899
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002900- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2901
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002902- Bug #1189330: configure did not correctly determine the necessary
2903 value of LINKCC if python was built with GCC 4.0.
2904
Trent Mick8321b422005-07-26 02:29:21 +00002905- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2906 vulnerability in zlib 1.2.1 and 1.2.2.
2907
Brett Cannon08cd5982005-04-24 22:26:38 +00002908- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2909 flags that change binary compatibility. Changes were also made to
2910 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002911 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002912
Bob Ippolitoed233462005-03-29 13:47:59 +00002913- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2914 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2915 no longer exists). This configure patch makes things right.
2916
Martin v. Löwise2713be2005-03-08 15:03:08 +00002917- Bug #1158607: Build with --disable-unicode again.
2918
Brett Cannon46d96232005-02-16 00:07:19 +00002919- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2920 defined. Discovered as a result of not being able to build on OS X.
2921
Brett Cannon516592f2004-12-07 00:42:59 +00002922- setup.py now uses the directories specified in LDFLAGS using the -L option
2923 and in CPPFLAGS using the -I option for adding library and include
2924 directories, respectively, for compiling extension modules against. This has
2925 led to the core being compiled using the values in CPPFLAGS. It also removes
2926 the need for the special-casing of both DarwinPorts and Fink for darwin since
2927 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2928 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2929 Fink, ``-I/opt/local/include`` for DarwinPorts).
2930
Brett Cannon43802422005-02-10 20:48:03 +00002931- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2932 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2933 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2934 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002936C API
2937-----
2938
Tim Petersc9d78aa2006-03-26 23:27:58 +00002939- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2940 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2941 is obtained via the ``PyObject_`` family, it must be released via the
2942 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2943 always been officially true, but when Python's small-object allocator was
2944 introduced, an attempt was made to cater to a few extension modules
2945 discovered at the time that obtained memory via ``PyObject_New`` but
2946 released it via ``PyMem_DEL``. It's years later, and if such code still
2947 exists it will fail now (probably with segfaults, but calling wrong
2948 low-level memory management functions can yield many symptoms).
2949
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002950- Added a C API for set and frozenset objects.
2951
Raymond Hettinger66517482004-12-03 11:45:13 +00002952- Removed PyRange_New().
2953
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002954- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2955 mapping argument now. This string is used as a mapping table. Byte values
2956 greater than the length of the string and 0xFFFE are treated as undefined
2957 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002964
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002965- Patch #1276356: New resource "urlfetch" is implemented. This enables
2966 even impatient people to run tests that require remote files.
