Georg Brandld59ea472007-03-08 18:37:35 +0000581- unittest now verifies more of its assumptions. In particular, TestCase
582 and TestSuite subclasses (not instances) are no longer accepted in

584 never made sense with ordinary subclasses -- the failure just occurred
585 later, with a more cumbersome exception.

882
Walter Dörwald93a36032007-04-21 10:31:43 +0000883- Fix utf-8-sig incremental decoder, which didn't recognise a BOM when the
884 first chunk fed to the decoder started with a BOM, but was longer than 3 bytes.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000939
940Core and builtins
941-----------------
942
Neal Norwitz24b6f202006-09-05 04:43:56 +0000943- Fix infinite recursion when subclassing long and overriding __hash__.
944
945- Fix concatenation (+=) of long strings.
946
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000947- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000948 compared equal or unequal to a string and a UnicodeDecodeError
949 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000950
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000951 Instead, the equal (==) and unequal (!=) comparison operators will
952 now issue a UnicodeWarning and interpret the two objects as
953 unequal. The UnicodeWarning can be filtered as desired using
954 the warning framework, e.g. silenced completely, turned into an
955 exception, logged, etc.
956
957 Note that compare operators other than equal and unequal will still
958 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000959
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000960- Fix segfault when doing string formatting on subclasses of long.
961
962- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
963 with new-style classes.
964
965- Fix bug related to __len__ functions returning negative values with
966 classic classes.
967
968- Patch #1538606, Fix __index__() clipping. There were some problems
969 discovered with the API and how integers that didn't fit into Py_ssize_t
970 were handled. This patch attempts to provide enough alternatives
971 to effectively use __index__.
972
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000973- Bug #1536021: __hash__ may now return long int; the final hash
974 value is obtained by invoking hash on the long int.
975
Thomas Hellerab1049c2006-08-08 17:37:00 +0000976- Bug #1536786: buffer comparison could emit a RuntimeWarning.
977
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000978- Bug #1535165: fixed a segfault in input() and raw_input() when
979 sys.stdin is closed.
980
Thomas Heller74d36f02006-08-04 18:17:40 +0000981- On Windows, the PyErr_Warn function is now exported from
982 the Python dll again.
983
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000984- Bug #1191458: tracing over for loops now produces a line event
985 on each iteration. Fixing this problem required changing the .pyc
986 magic number. This means that .pyc files generated before 2.5c1
987 will be regenerated.
988
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000989- Bug #1333982: string/number constants were inappropriately stored
990 in the byte code and co_consts even if they were not used, ie
991 immediately popped off the stack.
992
Georg Brandle9462c72006-08-04 18:03:37 +0000993- Fixed a reference-counting problem in property().

996Library
997-------
998
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000999- Fix a bug in the ``compiler`` package that caused invalid code to be
1000 generated for generator expressions.
1001
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001002- The distutils version has been changed to 2.5.0. The change to
1003 keep it programmatically in sync with the Python version running
1004 the code (introduced in 2.5b3) has been reverted. It will continue
1005 to be maintained manually as static string literal.
1006
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001007- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001008 and this cannot be converted to the required C type, an exception is
1009 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001010 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001011
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001012- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001013 an exception.
1014
Tim Peterscbdd3502006-09-05 01:47:53 +00001015- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001016 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001017 workarounds for clocks with low resolution, to stop the code yielding
1018 duplicate UUIDs.
1019
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001020- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1021 before raising SystemExit, allowing IDLE to honor quit() and exit().
1022
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001023- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1024
Georg Brandl7a1af772006-08-14 21:55:28 +00001025- Patch #1536071: trace.py should now find the full module name of a
1026 file correctly even on Windows.
1027
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001028- logging's atexit hook now runs even if the rest of the module has
1029 already been cleaned up.
1030
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001031- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001032
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001033- Bug #1531405, format_exception no longer raises an exception if
1034 str(exception) raised an exception.
1035
Neil Schemenauer06ded092006-08-04 16:20:30 +00001036- Fix a bug in the ``compiler`` package that caused invalid code to be
1037 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001047- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1048 raises the correct exceptions.
1049
Thomas Heller1ce433e2006-08-14 16:20:04 +00001050- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1051 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1052
Thomas Heller86720042006-08-14 11:17:48 +00001053- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1054 uses the _as_parameter_ attribute when objects are passed to foreign
1055 function calls. The ctypes version number was changed to 1.0.1.
1056
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001057- Bug #1530559, struct.pack raises TypeError where it used to convert.
1058 Passing float arguments to struct.pack when integers are expected
1059 now triggers a DeprecationWarning.

Neal Norwitza1f10902006-07-12 07:28:29 +00001108
1109Core and builtins
1110-----------------
1111
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001112- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001113 returned a long (see PEP 353).
1114
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001115- Bug #1515471: string.replace() accepts character buffers again.
1116
Neal Norwitz07aadb12006-07-30 06:55:48 +00001117- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1118 This provides the proper warning for struct.pack().
1119 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1120
Neal Norwitz0d62a062006-07-30 06:53:31 +00001121- Patch #1531113: Fix augmented assignment with yield expressions.
1122 Also fix a SystemError when trying to assign to yield expressions.
1123
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001124- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1125 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1126 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1127 excessive filesystem operations during imports.
1128
Tim Petersbc24eee2006-07-27 01:14:53 +00001129- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1130 operations on signed longs that are formally undefined by C.
1131 Unfortunately, at least one compiler now cares about that, so complicated
1132 the code to make that compiler happy again.
1133
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001134- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1135
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001136- Patch #1232023: Stop including current directory in search
1137 path on Windows.
1138
Neal Norwitze1fdb322006-07-21 05:32:28 +00001139- Fix some potential crashes found with failmalloc.
1140
Neal Norwitze7563102006-07-17 01:00:16 +00001141- Fix warnings reported by Klocwork's static analysis tool.
1142
Neal Norwitz84be93b2006-07-16 01:50:38 +00001143- Bug #1512814, Fix incorrect lineno's when code within a function
1144 had more than 255 blank lines.
1145
Georg Brandl9dceedb2006-07-12 15:31:17 +00001146- Patch #1521179: Python now accepts the standard options ``--help`` and
1147 ``--version`` as well as ``/?`` on Windows.
1148
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001149- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001150 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001151 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001152
Tim Peters112aad32006-07-19 00:03:19 +00001153- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001154 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001155 new ``sys._current_frames()`` returns a dictionary with one entry,
1156 mapping the faux "thread id" 0 to the current frame.
1157
Ronald Oussoren3075e162006-07-25 20:28:55 +00001158- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001159
Ronald Oussoren3075e162006-07-25 20:28:55 +00001160

1162-------
1163
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001164- Correction of patch #1455898: In the mbcs decoder, set final=False
1165 for stream decoder, but final=True for the decode function.
1166
Georg Brandl07fec3a2006-08-01 18:49:24 +00001167- os.urandom no longer masks unrelated exceptions like SystemExit or
1168 KeyboardInterrupt.
1169
Tim Peters4643c2f2006-08-10 22:45:34 +00001170- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001171 shutil.copytree on Windows
1172
Georg Brandle34ac7c2006-07-30 11:07:23 +00001173- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1174 refers to file descriptors, not file objects.
1175
Tim Peterscbdd3502006-09-05 01:47:53 +00001176- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001177 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001178 #1513611, and probably others.
1179
Georg Brandledd9b0d2006-07-29 09:33:26 +00001180- Bug #1441397: The compiler module now recognizes module and function
1181 docstrings correctly as it did in Python 2.4.
1182
Tim Peters6f681472006-07-27 23:44:37 +00001183- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1184 lost that tests are sorted by name before being run. This rarely
1185 matters for well-written tests, but can create baffling symptoms if
1186 side effects from one test to the next affect outcomes. ``DocTestFinder``
1187 has been changed to sort the list of tests it returns.
1188
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001189- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001190 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001191
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001192- Bug #978833: Really close underlying socket in _socketobject.close.
1193
Georg Brandldb232dc2006-08-20 13:15:43 +00001194- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1195 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001196
Georg Brandlcf0c1722006-07-26 07:23:32 +00001197- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1198 to recursive calls and call it with the failing package name.
1199
Martin v. Löwis0b483032006-07-25 09:53:12 +00001200- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1201
Georg Brandlc13c34c2006-07-24 14:09:56 +00001202- Patch #1515343: Fix printing of deprecated string exceptions with a
1203 value in the traceback module.
1204
Greg Ward48fae7a2006-07-23 16:05:51 +00001205- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1206
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001207- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1208
Brett Cannoncaebe222006-07-18 04:41:36 +00001209- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1210 argument tuple. For arguments where zero is illegal, the value is forced to
1211 the minimum value that is correct. This is to support an undocumented but
1212 common way people used to fill in inconsequential information in the time
1213 tuple pre-2.4.
1214
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001215- Patch #1220874: Update the binhex module for Mach-O.
1216
Barry Warsawb110bad2006-07-21 14:51:07 +00001217- The email package has improved RFC 2231 support, specifically for
1218 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1219 (name*0=<blah>) parameter continuations. This may change the types of
1220 values returned from email.message.Message.get_param() and friends.
1221 Specifically in some cases where non-encoded continuations were used,
1222 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1223 will just return the string (since non-encoded continuations don't have
1224 charset and language parts).
1225
1226 Also, whereas % values were decoded in all parameter continuations, they are
1227 now only decoded in encoded parameter parts.
1228
Ronald Oussoren3075e162006-07-25 20:28:55 +00001229- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1230
1231- Bug #1517996: IDLE now longer shows the default Tk menu when a
1232 path browser, class browser or debugger is the frontmost window on MacOS X
1233
Barry Warsaw00decd72006-07-27 23:43:15 +00001234- Patch #1520294: Support for getset and member descriptors in types.py,
1235 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1236 of an object against these built-in types and more importantly, for getting
1237 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001240Extension Modules
1241-----------------
1242
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001243- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1244 a socket operation on a socket with a timeout, the exception will be
1245 caught correctly. Previously, the exception was not caught.
1246
Thomas Heller1393d6a2006-07-28 21:43:20 +00001247- Patch #1529514: The _ctypes extension is now compiled on more
1248 openbsd target platforms.
1249
Tim Peters9cab5932006-07-28 00:30:00 +00001250- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1251 a memory leak, affecting pickles and deep copies.
1252
Tim Petersbc24eee2006-07-27 01:14:53 +00001253- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001254 Paul Eggert.
1255
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001256- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1257
Thomas Hellerce049a02006-07-14 17:51:14 +00001258- Patch #1521817: Index range checking on ctypes arrays containing
1259 exactly one element enabled again. This allows iterating over these
1260 arrays, without the need to check the array size before.
1261
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001262- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001263 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001264 /dev/null in certain cases; this is now fixed.
1265
Thomas Heller47d7a062006-07-12 08:43:47 +00001266- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1267 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001268
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001269- Because of a misspelled preprocessor symbol, ctypes was always
1270 compiled without thread support; this is now fixed.
1271
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001272- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1273 methods now allow their database parameter to be None as the
1274 sleepycat API allows.
1275
Matt Flemingec926502006-07-28 11:27:27 +00001276- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1277 bluetooth API compared with Linux and FreeBSD.
1278
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001279Tests
1280-----
1281
1282- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1283 how long the test file should take to play. Now accepts taking 2.93 secs
1284 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1285
Georg Brandl4793aa32006-07-28 18:31:39 +00001286- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1287 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1288 run via ``regrtest.py``. Now they do.

Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001290Build
1291-----
1292
1293- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1294
Ronald Oussoren26cad082006-08-01 21:00:57 +00001295Mac
1296---
1297
1298- PythonLauncher now works correctly when the path to the script contains
1299 characters that are treated specially by the shell (such as quotes).
1300
1301- Bug #1527397: PythonLauncher now launches scripts with the working directory
1302 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001303 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001304 expect.

1313-----------------
1314
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001315- Bug #1441486: The literal representation of -(sys.maxint - 1)
1316 again evaluates to a int object, not a long.
1317
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001318- Bug #1501934: The scope of global variables that are locally assigned
1319 using augmented assignment is now correctly determined.
1320
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001321- Bug #927248: Recursive method-wrapper objects can now safely
1322 be released.
1323
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001324- Bug #1417699: Reject locale-specific decimal point in float()
1325 and atof().
1326
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001327- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1328 omit a default "error" argument for NULL pointer. This allows
1329 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001330
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001331- Bug #1519018: 'as' is now validated properly in import statements.
1332
Neal Norwitz28746ab2006-07-09 22:14:42 +00001333- On 64 bit systems, int literals that use less than 64 bits are
1334 now ints rather than longs.
1335
Neal Norwitzed657552006-07-10 00:04:44 +00001336- Bug #1512814, Fix incorrect lineno's when code at module scope
1337 started after line 256.
1338
Tim Peters32a83612006-07-10 21:08:24 +00001339- New function ``sys._current_frames()`` returns a dict mapping thread
1340 id to topmost thread stack frame. This is for expert use, and is
1341 especially useful for debugging application deadlocks. The functionality
1342 was previously available in Fazal Majid's ``threadframe`` extension
1343 module, but it wasn't possible to do this in a wholly threadsafe way from
1344 an extension.
1345

1361
Thomas Woutersadd19112006-07-05 11:03:49 +00001362- string.Template() now correctly handles tuple-values. Previously,
1363 multi-value tuples would raise an exception and single-value tuples would
1364 be treated as the value they contain, instead.
1365
Martin v. Löwisede77f52006-07-03 13:01:35 +00001366- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1368
Martin v. Löwis45482392006-07-03 12:28:58 +00001369- Bug #1267547: Put proper recursive setup.py call into the
1370 spec file generated by bdist_rpm.
1371
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001372- Bug #1514693: Update turtle's heading when switching between
1373 degrees and radians.
1374
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001375- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001376 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001377
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001378- Bug #1514703: Only setup canvas window in turtle when the canvas
1379 is created.
1380
Martin v. Löwis7596e832006-07-01 15:33:37 +00001381- Bug #1513223: .close() of a _socketobj now releases the underlying
1382 socket again, which then gets closed as it becomes unreferenced.
1383
Fred Drake10497c82006-06-29 02:57:48 +00001384- Bug #1504333: Make sgmllib support angle brackets in quoted
1385 attribute values.
1386
1387- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1388 sgmllib ('[' and ']' were not accepted).
1389
Georg Brandl1be63af2006-06-28 20:23:25 +00001390- Fix a bug in the turtle module's end_fill function.
1391
Brett Cannon53ab5b72006-06-22 16:49:14 +00001392- Bug #1510580: The 'warnings' module improperly required that a Warning
1393 category be either a types.ClassType and a subclass of Warning. The proper
1394 check is just that it is a subclass with Warning as the documentation states.
1395
Georg Brandlad29e632006-06-21 17:45:17 +00001396- The compiler module now correctly compiles the new try-except-finally
1397 statement (bug #1509132).
1398
Neal Norwitz60373cd2006-06-22 06:30:50 +00001399- The wsgiref package is now installed properly on Unix.
1400
Vinay Sajip28e57612006-07-01 10:45:20 +00001401- A bug was fixed in logging.config.fileConfig() which caused a crash on
1402 shutdown when fileConfig() was called multiple times.
1403
Gerhard Häring762fbd32006-07-02 17:48:30 +00001404- The sqlite3 module did cut off data from the SQLite database at the first
1405 null character before sending it to a custom converter. This has been fixed
1406 now.
1407
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001408Extension Modules
1409-----------------
1410
Tim Peters112aad32006-07-19 00:03:19 +00001411- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1412 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1413 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001414
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001415- Assigning None to pointer type fields in ctypes structures possible
1416 overwrote the wrong fields, this is fixed now.
1417
1418- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1419 on non-Windows platforms.
1420
1421- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1422 integer or long, without range checking.
1423
1424- Patch #1517790: It is now possible to use custom objects in the ctypes
1425 foreign function argtypes sequence as long as they provide a from_param
1426 method, no longer is it required that the object is a ctypes type.
1427
1428- The '_ctypes' extension module now works when Python is configured
1429 with the --without-threads option.
1430
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001431- Bug #1513646: os.access on Windows now correctly determines write
1432 access, again.
1433
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001434- Bug #1512695: cPickle.loads could crash if it was interrupted with
1435 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001437- Bug #1296433: parsing XML with a non-default encoding and
1438 a CharacterDataHandler could crash the interpreter in pyexpat.
1439
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001440- Patch #1516912: improve Modules support for OpenVMS.

1446
Tim Peters32a83612006-07-10 21:08:24 +00001447- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001448 Previously, the slight difference could cause compilation errors of the
1449 'zlib' module on systems with more than one version of zlib.
1450
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001451- The MSI compileall step was fixed to also support a TARGETDIR
1452 with spaces in it.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001481
1482Core and builtins
1483-----------------
1484
Georg Brandla56b9152006-06-19 06:35:54 +00001485- Patch #1507676: Error messages returned by invalid abstract object operations
1486 (such as iterating over an integer) have been improved and now include the
1487 type of the offending object to help with debugging.
1488
Brett Cannonea3912b2006-06-13 21:46:41 +00001489- Bug #992017: A classic class that defined a __coerce__() method that returned
1490 its arguments swapped would infinitely recurse and segfault the interpreter.
1491
Neal Norwitz909eb122006-06-12 02:13:21 +00001492- Fix the socket tests so they can be run concurrently.
1493
Neal Norwitzb9845e72006-06-12 02:11:18 +00001494- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001495 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001496
Brett Cannon22565aa2006-06-09 22:31:23 +00001497- Bug #532646: object.__call__() will continue looking for the __call__
1498 attribute on objects until one without one is found. This leads to recursion
1499 when you take a class and set its __call__ attribute to an instance of the
1500 class. Originally fixed for classic classes, but this fix is for new-style.
1501 Removes the infinite_rec_3 crasher.
1502
Georg Brandl24250812006-06-09 18:45:48 +00001503- The string and unicode methods startswith() and endswith() now accept
1504 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1505
Brett Cannonde3b0522006-06-08 17:00:45 +00001506- Buffer objects, at the C level, never used the char buffer
1507 implementation even when the char buffer for the wrapped object was
1508 explicitly requested (originally returned the read or write buffer).
1509 Now a TypeError is raised if the char buffer is not present but is
1510 requested.
1511
Georg Brandlddbaa662006-06-04 21:56:52 +00001512- Patch #1346214: Statements like "if 0: suite" are now again optimized
1513 away like they were in Python 2.4.
1514
Georg Brandlb7c8f542006-05-27 12:30:25 +00001515- Builtin exceptions are now full-blown new-style classes instead of
1516 instances pretending to be classes, which speeds up exception handling
1517 by about 80% in comparison to 2.5a2.
1518
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001519- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1520 Unicode 4.1.
1521
Georg Brandlf4ef1162006-05-26 18:03:31 +00001522- Patch #921466: sys.path_importer_cache is now used to cache valid and
1523 invalid file paths for the built-in import machinery which leads to
1524 fewer open calls on startup.
1525
Tim Peters696cf432006-05-24 21:10:40 +00001526- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1527 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1528 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1529 the number of input digits (it was and remains linear-time for bases
1530 2, 4, 8, 16 and 32).
1531
Tim Petersb713ec22006-05-23 18:45:30 +00001532- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1533 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1534 an integer close to ``sys.maxint``. This was repaired by patch
1535 #1335972, which also gives a nice speedup.
1536
Richard Jonescebbefc2006-05-23 18:28:17 +00001537- Patch #1337051: reduced size of frame objects.
1538
1539- PyErr_NewException now accepts a tuple of base classes as its
1540 "base" parameter.
1541
Richard Jones7c88dcc2006-05-23 10:37:38 +00001542- Patch #876206: function call speedup by retaining allocated frame
1543 objects.
1544
Georg Brandl7b90e162006-05-18 07:01:27 +00001545- Bug #1462152: file() now checks more thoroughly for invalid mode
1546 strings and removes a possible "U" before passing the mode to the
1547 C library function.
1548
Neal Norwitz1004a532006-05-15 07:17:23 +00001549- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1550
Neal Norwitz373f0a72006-05-15 07:04:36 +00001551- Bug #1487966: Fix SystemError with conditional expression in assignment
1552
Martin v. Löwis879768d2006-05-11 13:28:43 +00001553- WindowsError now has two error code attributes: errno, which carries
1554 the error values from errno.h, and winerror, which carries the error
1555 values from winerror.h. Previous versions put the winerror.h values
1556 (from GetLastError()) into the errno attribute.
1557
Martin v. Löwis77736712006-05-04 05:51:03 +00001558- Patch #1475845: Raise IndentationError for unexpected indent.
1559
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001560- Patch #1479181: split open() and file() from being aliases for each other.
1561
Tim Peters44bd9862006-06-01 13:49:23 +00001562- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1563 methods were always silently ignored by dictionaries when comparing keys.
1564 They are now passed through (except when using the C API function
1565 ``PyDict_GetItem()``, whose semantics did not change).
1566
1567- Bug #1456209: In some obscure cases it was possible for a class with a
1568 custom ``__eq__()`` method to confuse dict internals when class instances
1569 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1570 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001572Extension Modules
1573-----------------
1574
Trent Mick960a3f82006-06-28 20:30:41 +00001575- Bug #1295808: expat symbols should be namespaced in pyexpat
1576
1577- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1578
Brett Cannon6ee7d012006-06-08 16:23:04 +00001579- Change binascii.hexlify to accept a read-only buffer instead of only a char
1580 buffer and actually follow its documentation.
1581
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001582- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1583
Nick Coghlanc649ec52006-05-29 12:43:05 +00001584- Patch #1478788 (modified version): The functional extension module has
1585 been renamed to _functools and a functools Python wrapper module added.
1586 This provides a home for additional function related utilities that are
1587 not specifically about functional programming. See PEP 309.
1588
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001589- Patch #1493701: performance enhancements for struct module.
1590
Georg Brandl378d5922006-05-17 14:26:50 +00001591- Patch #1490224: time.altzone is now set correctly on Cygwin.
1592
Georg Brandl8d3342b2006-05-16 07:38:27 +00001593- Patch #1435422: zlib's compress and decompress objects now have a
1594 copy() method.
1595
Andrew MacIntyre92913322006-06-13 15:04:24 +00001596- Patch #1454481: thread stack size is now tunable at runtime for thread
1597 enabled builds on Windows and systems with Posix threads support.
1598
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001599- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1600 (up to the system limit of 32K characters).
1601
1602- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1603 As a result, these functions now raise WindowsError instead of OSError.
1604
Tim Peters7a822da2006-05-25 21:50:17 +00001605- ``time.clock()`` on Win64 should use the high-performance Windows
1606 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1607 Windows platforms).
1608
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001609- Calling Tk_Init twice is refused if the first call failed as that
1610 may deadlock.
1611
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001612- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1613 accept it without potentially using an uninitialized pointer.
1614
1615- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1616 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1617 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001618
Gregory P. Smith372b5832006-06-05 18:48:21 +00001619- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001620 [pybsddb project SF patch number 1466734]
1621
Gregory P. Smith372b5832006-06-05 18:48:21 +00001622- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1623 parameter is supplied. [SF pybsddb bug #1477863]
1624
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001625- bsddb: the __len__ method of a DB object has been fixed to return correct
1626 results. It could previously incorrectly return 0 in some cases.
1627 Fixes SF bug 1493322 (pybsddb bug 1184012).
1628
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001629- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1630 aborts the db transaction safely when a modifier callback fails.
1631 Fixes SF python patch/bug #1408584.
1632
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001633- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001634 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001635 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1636 database calls that would previously deadlock. [SF python bug #775414]
1637
Vinay Sajip28e57612006-07-01 10:45:20 +00001638- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001639
Walter Dörwald4994d952006-06-19 08:07:50 +00001640- Patch #1506645: add Python wrappers for the curses functions
1641 is_term_resized, resize_term and resizeterm.

1644-------
1645
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001646- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1647 functions.
1648
Martin v. Löwis3798da02006-06-17 18:44:27 +00001649- Patch #812986: Update turtle output even if not tracing.
1650
Vinay Sajip28e57612006-07-01 10:45:20 +00001651- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001652 Tkinter.BaseWidget.
1653
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001654- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1655
Martin v. Löwis337487e2006-06-17 09:15:14 +00001656- Patch #763580: Add name and value arguments to Tkinter variable
1657 classes.
1658
Georg Brandl83cc0d02006-06-14 08:50:03 +00001659- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1660 mime.types file for determining MIME types.
1661
Georg Brandl2605ca82006-06-14 06:08:31 +00001662- Bug #1339007: Shelf objects now don't raise an exception in their
1663 __del__ method when initialization failed.
1664
Martin v. Löwisd8251432006-06-14 05:21:04 +00001665- Patch #1455898: The MBCS codec now supports the incremental mode for
1666 double-byte encodings.
1667
Tim Peters43898b42006-06-14 04:09:25 +00001668- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1669 guarantee that adjacent triples in the return list always describe
1670 non-adjacent blocks. Previously, a pair of matching blocks could end
1671 up being described by multiple adjacent triples that formed a partition
1672 of the matching pair.
1673
Greg Ward0e0c9f42006-06-11 16:24:11 +00001674- Bug #1498146: fix optparse to handle Unicode strings in option help,
1675 description, and epilog.
1676
Greg Wardd1c797e2006-06-11 14:42:41 +00001677- Bug #1366250: minor optparse documentation error.
1678
Greg Ward7f547402006-06-11 00:40:49 +00001679- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1680 clarify docs.
1681
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001682- The wsgiref package has been added to the standard library.
1683
Nick Coghlan676725d2006-06-08 13:54:49 +00001684- The functions update_wrapper() and wraps() have been added to the functools
1685 module. These make it easier to copy relevant metadata from the original
1686 function when writing wrapper functions.
1687
Tim Petersd6a9eef2006-06-05 01:48:21 +00001688- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1689 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001690
Martin v. Löwis3f767792006-06-04 19:36:28 +00001691- Patch #1359618: Speed up charmap encoder by using a trie structure
1692 for lookup.
1693
Tim Petersd609b1a2006-06-02 23:22:51 +00001694- The functions in the ``pprint`` module now sort dictionaries by key
1695 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1696 if and only if its display required more than one line, although that
1697 wasn't documented. The new behavior increases predictability; e.g.,
1698 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1699
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001700- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1701 (thanks for J. J. Lee).
1702
Georg Brandl2b330372006-05-28 20:23:12 +00001703- Patch #1496206: improve urllib2 handling of passwords with respect to
1704 default HTTP and HTTPS ports.
1705
George Yoshidaf3c65de2006-05-28 16:39:09 +00001706- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1707
Bob Ippolito7298f272006-05-23 18:43:47 +00001708- Patch #1281707: speed up gzip.readline.
1709
Georg Brandlb89316f2006-05-17 15:51:16 +00001710- Patch #1180296: Two new functions were added to the locale module:
1711 format_string() to get the effect of "format % items" but locale-aware,
1712 and currency() to format a monetary number with currency sign.
1713
Georg Brandle3a25832006-05-17 14:56:04 +00001714- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1715 and several features added, such as speed and geometry control.
1716
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001717- Patch #1488881: add support for external file objects in bz2 compressed
1718 tarfiles.
1719
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001720- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1721 stdout arguments, making it possible to redirect input and output
1722 for remote debugging.
1723
1724- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1725 a couple of issues, notably handling of long file names using the
1726 GNU LONGNAME extension.
1727
1728- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1729 new flag when ``name`` is already the name of an option flag.
1730
1731- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1732 package.
1733
1734- Patch #1472854: make the rlcompleter.Completer class usable on non-
1735 UNIX platforms.
1736
1737- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1738
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001739- Bug #1472827: correctly escape newlines and tabs in attribute values in
1740 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001770What's New in Python 2.5 alpha 2?
1771=================================
1772
1773*Release date: 27-APR-2006*
1774
1775Core and builtins
1776-----------------
1777
Thomas Heller1b046642006-04-18 18:51:06 +00001778- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1779 by converting these apis from macros into exported functions again:
1780
1781 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1782 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1783 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1784 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1785 PyRun_String Py_CompileString
1786
Martin v. Löwis45294a92006-04-18 06:24:08 +00001787- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1788
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001789- All uses of PyStructSequence_InitType have been changed to initialize
1790 the type objects only once, even if the interpreter is initialized
1791 multiple times.
1792
Neal Norwitz61546162006-04-14 05:20:28 +00001793- Bug #1454485, array.array('u') could crash the interpreter. This was
1794 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1795 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1796
1797- Py_UNICODE is unsigned. It was always documented as unsigned, but
1798 due to a bug had a signed value in previous versions.
1799
Tim Peters3a5e8b12006-04-11 01:44:07 +00001800- Patch #837242: ``id()`` of any Python object always gives a positive
1801 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1802 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001803 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001804 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001805
Tim Peters3a5e8b12006-04-11 01:44:07 +00001806 def __hash__(self):
1807 return id(self) # WRONG
1808
1809 because a hash result must be a (short) Python int but it was always
1810 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001811 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001812 was always usable as a hash value before this patch. That's no longer
1813 necessarily so.
1814
1815- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001816 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001817 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001818 #1454844)
1819
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001820- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1821 involving generators that have paused outside of any ``try`` or ``with``
1822 blocks. (In 2.5a1, a paused generator that was part of a reference
1823 cycle could not be garbage collected, regardless of whether it was
1824 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001825
Anthony Baxter51bcb682006-04-05 14:51:42 +00001826Extension Modules
1827-----------------
1828
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001829- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1830 is a macro.
1831
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001832- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1833 fails with an error condition.
1834
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001835- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1836
1837- Bug #1117761: bsddb.*open() no longer raises an exception when using
1838 the cachesize parameter.
1839
1840- Bug #1149413: bsddb.*open() no longer raises an exception when using
1841 a temporary db (file=None) with the 'n' flag to truncate on open.
1842
1843- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1844 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001845
Armin Rigoa9017c32006-04-19 11:50:27 +00001846- Patch #1062014: AF_UNIX sockets under Linux have a special
1847 abstract namespace that is now fully supported.
1848
Anthony Baxter51bcb682006-04-05 14:51:42 +00001849Library
1850-------
1851
Peter Astrand7d1d4362006-07-14 14:04:45 +00001852- Bug #1223937: subprocess.CalledProcessError reports the exit status
1853 of the process using the returncode attribute, instead of
1854 abusing errno.
1855
Tim Peters711bf302006-04-25 03:31:36 +00001856- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1857 a doctest to be skipped (the code is not run, and the expected output
1858 or exception is ignored).
1859
Nick Coghlanda2268f2006-04-24 04:37:15 +00001860- Fixed contextlib.nested to cope with exceptions being raised and
1861 caught inside exit handlers.
1862
Greg Wardab05edc2006-04-23 03:47:58 +00001863- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1864 hex, octal, or binary; add ``append_const`` action; keep going if
1865 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1866 added ``epilog`` for better help generation).
1867
Tim Peters21fbd572006-04-21 21:18:10 +00001868- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1869 called from a thread spawned as a side effect of importing a module.
1870
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001871- The pydoc module now supports documenting packages contained in
1872 .zip or .egg files.
1873
1874- The pkgutil module now has several new utility functions, such
1875 as ``walk_packages()`` to support working with packages that are either
1876 in the filesystem or zip files.
1877
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001878- The mailbox module can now modify and delete messages from
1879 mailboxes, in addition to simply reading them. Thanks to Gregory
1880 K. Johnson for writing the code, and to the 2005 Google Summer of
1881 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001882
Tim Petersc7605f22006-04-17 21:12:33 +00001883- The ``__del__`` method of class ``local`` in module ``_threading_local``
1884 returned before accomplishing any of its intended cleanup.
1885
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001886- Patch #790710: Add breakpoint command lists in pdb.
1887
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001888- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1889
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001890- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1891
Anthony Baxtere29002c2006-04-12 12:07:31 +00001892- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1893 Windows. Bug #1469163.
1894
Phillip J. Eby47032112006-04-11 01:07:43 +00001895- The warnings, linecache, inspect, traceback, site, and doctest modules
1896 were updated to work correctly with modules imported from zipfiles or
1897 via other PEP 302 __loader__ objects.
1898
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001899- Patch #1467770: Reduce usage of subprocess._active to processes which
1900 the application hasn't waited on.
1901
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001902- Patch #1462222: Fix Tix.Grid.
1903
Neal Norwitza31bf182006-04-09 03:35:43 +00001904- Fix exception when doing glob.glob('anything*/')
1905
Skip Montanaro262fb922006-04-21 02:31:07 +00001906- The pstats.Stats class accepts an optional stream keyword argument to
1907 direct output to an alternate file-like object.
1908
Anthony Baxter51bcb682006-04-05 14:51:42 +00001909Build
1910-----
1911
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001912- The Makefile now has a reindent target, which runs reindent.py on
1913 the library.
1914
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001915- Patch #1470875: Building Python with MS Free Compiler
1916
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001917- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001918
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001919- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1920 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001921 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001922 CXX from --with-cxx-main, see description in README.
1923
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001924- Patch #1429775: Link extension modules with the shared libpython.
1925
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001926- Fixed a libffi build problem on MIPS systems.
1927
Tim Peters8931ff12006-05-13 23:28:20 +00001928- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1929 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1930 and "%zu" for unsigned integers of type ``size_t``.
1931
Anthony Baxter51bcb682006-04-05 14:51:42 +00001932Tests
1933-----
1934
Nick Coghlanda2268f2006-04-24 04:37:15 +00001935- test_contextlib now checks contextlib.nested can cope with exceptions
1936 being raised and caught inside exit handlers.
1937
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001938- test_cmd_line now checks operation of the -m and -c command switches
1939
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001940- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1941 it separately and by hand. It also wasn't cleaning up its changes to
1942 the current Decimal context.
1943
Thomas Woutersabd08882006-04-26 15:53:30 +00001944- regrtest.py now has a -M option to run tests that test the new limits of
1945 containers, on 64-bit architectures. Running these tests is only sensible
1946 on 64-bit machines with more than two gigabytes of memory. The argument
1947 passed is the maximum amount of memory for the tests to use.
1948
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001949Tools
1950-----
1951
1952- Added the Python benchmark suite pybench to the Tools/ directory;
1953 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001954
Anthony Baxter51bcb682006-04-05 14:51:42 +00001955Documentation
1956-------------
1957
Tim Petersb06d28c2006-05-12 01:57:59 +00001958- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1959
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001960- PEP 343: Added Context Types section to the library reference
1961 and attempted to bring other PEP 343 related documentation into
1962 line with the implementation and/or python-dev discussions.
1963
Tim Peters8dc73d22006-04-24 02:03:16 +00001964- Bug #1337990: clarified that ``doctest`` does not support examples
1965 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001966
1967
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001968What's New in Python 2.5 alpha 1?
1969=================================
1970
Anthony Baxterebed3f62006-04-03 15:03:44 +00001971*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001972
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001973Core and builtins
1974-----------------
1975
Nick Coghlan43832302006-04-23 17:04:07 +00001976- PEP 338: -m command line switch now delegates to runpy.run_module
1977 allowing it to support modules in packages and zipfiles
1978
Martin v. Löwisc661b882006-04-20 04:54:23 +00001979- On Windows, .DLL is not an accepted file name extension for
1980 extension modules anymore; extensions are only found if they
1981 end in .PYD.
1982
Martin v. Löwisea62d252006-04-03 10:56:49 +00001983- Bug #1421664: sys.stderr.encoding is now set to the same value as
1984 sys.stdout.encoding.
1985
Neal Norwitz92e212f2006-04-03 04:48:37 +00001986- __import__ accepts keyword arguments.
1987
Georg Brandlccadf842006-03-31 18:54:53 +00001988- Patch #1460496: round() now accepts keyword arguments.
1989
Anthony Baxter262c00a2006-03-30 10:53:17 +00001990- Fixed bug #1459029 - unicode reprs were double-escaped.
1991
Hye-Shik Changd478f342006-03-23 12:32:36 +00001992- Patch #1396919: The system scope threads are reenabled on FreeBSD
1993 5.4 and later versions.
1994
Neal Norwitze98ccf62006-03-23 05:39:47 +00001995- Bug #1115379: Compiling a Unicode string with an encoding declaration
1996 now gives a SyntaxError.
1997
Georg Brandlabd1ff82006-03-18 07:59:59 +00001998- Previously, Python code had no easy way to access the contents of a
1999 cell object. Now, a ``cell_contents`` attribute has been added
2000 (closes patch #1170323).
2001
Tim Peterscf79aac2006-03-16 01:14:46 +00002002- Patch #1123430: Python's small-object allocator now returns an arena to
2003 the system ``free()`` when all memory within an arena becomes unused
2004 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2005 freed. Some applications will see a drop in virtual memory size now,
2006 especially long-running applications that, from time to time, temporarily
2007 use a large number of small objects. Note that when Python returns an
2008 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002009 platform C library will in turn return that memory to the operating system.
2010 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002011 appears to be effective at least on Microsoft C and gcc-based systems.
2012 Thanks to Evan Jones for hard work and patience.
2013
Georg Brandl533ff6f2006-03-08 18:09:27 +00002014- Patch #1434038: property() now uses the getter's docstring if there is
2015 no "doc" argument given. This makes it possible to legitimately use
2016 property() as a decorator to produce a read-only property.
2017
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002018- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2019 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2020 of requiring an int or long in slicing and a few other contexts, enabling
2021 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2022
Neal Norwitz995acdf2006-03-07 05:01:00 +00002023- Fixed various bugs reported by Coverity's Prevent tool.
2024
Brett Cannonbf364092006-03-01 04:25:17 +00002025- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2026 new exception base class, BaseException, which has a new message attribute.
2027 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2028 Raising a string exception now raises a DeprecationWarning.
2029
Thomas Woutersfb609f42006-02-28 16:37:25 +00002030- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2031 explicitly relative, using 'from .module import name' to mean 'from the same
2032 package as this module is in. Imports without dots still default to the
2033 old relative-then-absolute, unless 'from __future__ import
2034 absolute_import' is used.
2035
Brett Cannona7446e32006-02-27 23:39:10 +00002036- Properly check if 'warnings' raises an exception (usually when a filter set
2037 to "error" is triggered) when raising a warning for raising string
2038 exceptions.
2039
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002040- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002041 The name was removed from Include/code.h.
2042
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002043- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002044
Guido van Rossum1968ad32006-02-25 22:38:04 +00002045- Patch 1433928:
2046 - The copy module now "copies" function objects (as atomic objects).
2047 - dict.__getitem__ now looks for a __missing__ hook before raising
2048 KeyError.
2049
Tim Peters84ef21c2006-02-28 20:39:06 +00002050- PEP 343: with statement implemented. Needs ``from __future__ import
2051 with_statement``. Use of 'with' as a variable will generate a warning.
2052 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002053 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002054 The following objects have __context__ methods:
2055 - The built-in file type.
2056 - The thread.LockType type.
2057 - The following types defined by the threading module:
2058 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2059 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002060
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002061- Fix the encodings package codec search function to only search
2062 inside its own package. Fixes problem reported in patch #1433198.
2063
2064 Note: Codec packages should implement and register their own
2065 codec search function. PEP 100 has the details.
2066
Tim Peters9ea89d22006-06-04 03:26:02 +00002067- PEP 353: Using ``Py_ssize_t`` as the index type.
2068
2069- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2070 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2071 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2072 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2073 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002074
Neal Norwitzfc76d632006-01-10 06:03:13 +00002075- Patch #1400181, fix unicode string formatting to not use the locale.
2076 This is how string objects work. u'%f' could use , instead of .
2077 for the decimal point. Now both strings and unicode always use periods.
2078
Neal Norwitz671b9e32006-01-09 07:07:12 +00002079- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2080 configure would break checking curses.h.
2081
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002082- Bug #959576: The pwd module is now builtin. This allows Python to be
2083 built on UNIX platforms without $HOME set.
2084
Neal Norwitzc10978f2005-12-19 06:07:16 +00002085- Bug #1072182, fix some potential problems if characters are signed.
2086
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002087- Bug #889500, fix line number on SyntaxWarning for global declarations.
2088
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002089- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2090
Neal Norwitze7214a12005-12-18 05:03:17 +00002091- Support for converting hex strings to floats no longer works.
2092 This was not portable. float('0x3') now raises a ValueError.
2093
Barry Warsaw2a38a862005-12-18 01:27:35 +00002094- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002095 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002096 is now displayed in interactive prompt banner.
2097
Georg Brandlfa166682005-12-17 21:45:17 +00002098- Implementation of PEP 341 - Unification of try/except and try/finally.
2099 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002100 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002101
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002102- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2103 now encodes backslash correctly.
2104
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002105- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2106
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002107- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002108 and long longs.
2109
Neal Norwitz67715f02005-11-09 06:59:35 +00002110- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002111 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002112 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002113
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002114- Replaced most Unicode charmap codecs with new ones using the
2115 new Unicode translate string feature in the builtin charmap
2116 codec; the codecs were created from the mapping tables available
2117 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2118 encodings now include a mapping for the Apple logo)
2119
Tim Peterse3547fd2005-12-16 23:13:57 +00002120- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002121
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002122- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002123
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002124- A new AST parser implementation was completed. The abstract
2125 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002126 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002127
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002128- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002129 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2130
Neal Norwitz708e51a2005-10-03 04:48:15 +00002131- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2132
Neal Norwitz11bd1192005-10-03 00:54:56 +00002133- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2134 Provide a warning when a directory is passed on the command line.
2135
Neal Norwitz40d37812005-10-02 01:48:49 +00002136- Fix segfault with invalid coding.
2137
2138- SF bug #772896: unknown encoding results in MemoryError.
2139
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002140- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002141 supported a __len__() method which evaluated to False when the iterator
2142 was empty.
2143
Guido van Rossum630db602005-09-20 18:49:54 +00002144- On 64-bit platforms, when __len__() returns a value that cannot be
2145 represented as a C int, raise OverflowError.
2146
Skip Montanarof8948ca2005-09-19 03:54:46 +00002147- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002148 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002149
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002150- SF bug #893549: parsing keyword arguments was broken with a few format
2151 codes.
2152
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002153- Changes donated by Elemental Security to make it work on AIX 5.3
2154 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2155 bug #105470: test_pwd fails on 64bit system (Opteron).
2156
Guido van Rossum539c6622005-09-14 17:49:54 +00002157- Changes donated by Elemental Security to make it work on HP-UX 11 on
2158 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2159
Georg Brandl4550b8d2005-08-26 06:43:52 +00002160- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002161 (fixes bug #1119418).
2162
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002163- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2164
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002165- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2166 exceptions that cause a function to exit.
2167
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002168- The implementation of set() and frozenset() was revised to use its
2169 own internal data structure. Memory consumption is reduced by 1/3
2170 and there are modest speed-ups as well. The API is unchanged.
2171
Tim Petersde7990b2005-07-17 23:45:23 +00002172- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2173
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002174- SF bug #1229429: PyObject_CallMethod failed to decrement some
2175 reference counts in some error exit cases.
2176
Tim Petersecc6e6a2005-07-10 22:30:55 +00002177- SF bug #1185883: Python's small-object memory allocator took over
2178 a block managed by the platform C library whenever a realloc specified
2179 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002180 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002181 portable way to copy data from the C-managed block into Python's
2182 small-object space without risking a memory fault. Python's small-object
2183 realloc now leaves such blocks under the control of the platform C
2184 realloc.
2185
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002186- SF bug #1232517: An overflow error was not detected properly when
2187 attempting to convert a large float to an int in os.utime().
2188
Raymond Hettinger3296e692005-06-29 23:29:56 +00002189- SF bug #1224347: hex longs now print with lowercase letters just
2190 like their int counterparts.
2191
Michael W. Hudson188d4362005-06-20 16:52:57 +00002192- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2193 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2194 interpreter states; back out that fix and do a better job (see
2195 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2196 for a longer write-up of the problem).
2197
Michael W. Hudsondf888462005-06-03 14:41:55 +00002198- SF patch #1180995: marshal now uses a binary format by default when
2199 serializing floats.
2200
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002201- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2202 the routines that promise to produce IEEE 754 binary representations
2203 of floats now simply copy bytes around.
2204
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002205- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2206 278.
2207
Brett Cannonc3647ac2005-04-26 03:45:26 +00002208- patch #1109424: int, long, float, complex, and unicode now check for the
2209 proper magic slot for type conversions when subclassed. Previously the
2210 magic slot was ignored during conversion. Semantics now match the way
2211 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002212 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002213 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002214 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002215
Barry Warsawc8d907c2005-04-19 23:43:40 +00002216- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2217 NULL, now raise an AttributeError when attempting to set or delete the
2218 attribute. Previously a TypeError was raised, but this was inconsistent
2219 with the equivalent pure-Python implementation.
2220
Michael W. Hudson774479c2005-04-18 08:46:17 +00002221- It is now safe to call PyGILState_Release() before
2222 PyEval_InitThreads() (note that if there is reason to believe there
2223 are multiple threads around you still must call PyEval_InitThreads()
2224 before using the Python API; this fix is for extension modules that
2225 have no way of knowing if Python is multi-threaded yet).
2226
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002227- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2228 disabled caused a crash.
2229
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002230- Bug #1165306: instancemethod_new allowed the creation of a method
2231 with im_class == im_self == NULL, which caused a crash when called.
2232
Tim Petersecc6e6a2005-07-10 22:30:55 +00002233- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002234 fixes the crash seen in bug #1165761
2235
Raymond Hettinger96229b12005-03-11 06:49:40 +00002236- Added two new builtins, any() and all().
2237
Brett Cannon409d8f22005-03-05 06:47:57 +00002238- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002239 (e.g., ``class C(): pass`` is no longer a syntax error).
2240 Patch #1176012 added support to the 'parser' module and 'compiler' package
2241 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002242
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002243- Patch #1115086: Support PY_LONGLONG in structmember.
2244
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002245- Bug #1155938: new style classes did not check that __init__() was
2246 returning None.
2247
Tim Petersecc6e6a2005-07-10 22:30:55 +00002248- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002249 ('\') with a specific error message.
2250
Martin v. Löwisff232d72005-03-03 09:24:38 +00002251- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2252
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002253- Bug #1124295: the __name__ attribute of file objects was
2254 inadvertently made inaccessible in restricted mode.
2255
Tim Petersecc6e6a2005-07-10 22:30:55 +00002256- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002257 an ferror() call.
2258
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002259- min() and max() now support key= arguments with the same meaning as in
2260 list.sort().
2261
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002262- The peephole optimizer now performs simple constant folding in expressions:
2263 (2+3) --> (5).
2264
Raymond Hettingera422c342005-01-11 03:03:27 +00002265- set and frozenset objects can now be marshalled. SF #1098985.
2266
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002267- Bug #1077106: Poor argument checking could cause memory corruption
2268 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002269
Jeremy Hyltonab630502005-02-04 18:44:06 +00002270- The parser did not complain about future statements in illegal
2271 positions. It once again reports a syntax error if a future
2272 statement occurs after anything other than a doc string.
2273
Neil Schemenauercf52c072005-08-12 17:34:58 +00002274- Change the %s format specifier for str objects so that it returns a
2275 unicode instance if the argument is not an instance of basestring and
2276 calling __str__ on the argument returns a unicode instance.
2277
Tim Petersf4e69282006-02-27 17:15:31 +00002278- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2279 current thread state when the auto-GIL-state machinery knows about
2280 it (since the thread state is being deleted, continuing to remember it
2281 can't help, but can hurt if another thread happens to get created with
2282 the same thread id).
2283
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002284Extension Modules
2285-----------------
2286
Georg Brandl43f08a82006-03-31 18:01:16 +00002287- Patch #1380952: fix SSL objects timing out on consecutive read()s
2288
Neal Norwitz05a45592006-03-20 06:30:08 +00002289- Patch #1309579: wait3 and wait4 were added to the posix module.
2290
Anthony Baxterfa869072006-03-20 05:21:58 +00002291- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2292 In addition, the existing ulaw code was updated.
2293
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002294- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002295 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002296
Neal Norwitz10be10c2006-03-16 06:50:13 +00002297- Everything under lib-old was removed. This includes the following modules:
2298 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002299 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002300 util, whatsound, whrandom, zmod
2301
2302- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2303
2304- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002305 is deprecated. The undocumented re.engine variable no longer exists.
2306
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002307- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2308 SS2 (single-shift 2) escape sequences correctly.
2309
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002310- The unicodedata module was updated to the 4.1 version of the Unicode
2311 database. The 3.2 version is still available as unicodedata.db_3_2_0
2312 for applications that require this specific version (such as IDNA).
2313
Neal Norwitzb62c4332006-03-04 18:35:47 +00002314- The timing module is no longer built by default. It was deprecated
2315 in PEP 4 in Python 2.0 or earlier.
2316
Guido van Rossum1968ad32006-02-25 22:38:04 +00002317- Patch 1433928: Added a new type, defaultdict, to the collections module.
2318 This uses the new __missing__ hook behavior added to dict (see above).
2319
Georg Brandldbd83392006-02-20 09:42:33 +00002320- Bug #854823: socketmodule now builds on Sun platforms even when
2321 INET_ADDRSTRLEN is not defined.
2322
Georg Brandlf4f44152006-02-18 22:29:33 +00002323- Patch #1393157: os.startfile() now has an optional argument to specify

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002474- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2475 been renamed to have only a single underscore prefix. This was done to
2476 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002477
Nick Coghlan43832302006-04-23 17:04:07 +00002478- PEP 338: new module runpy defines a run_module function to support
2479 executing modules which provide access to source code or a code object
2480 via the PEP 302 import mechanisms.
2481
Anthony Baxter93f5b932006-04-03 08:05:07 +00002482- The email module's parsedate_tz function now sets the daylight savings

2490 in attribute values.
2491
Anthony Baxterc51ee692006-04-01 00:57:31 +00002492- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002493 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002494 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002495 module will not be built.
2496
Tim Petersc17976e2006-04-01 00:26:53 +00002497- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2498 aren't officially supported here, and trying to use them will probably
2499 raise an exception some day. But dicts have been allowed, and "mostly
2500 worked", so support for them won't go away without warning.
2501
Georg Brandl338ef7d2006-03-31 18:42:16 +00002502- Bug #1445068: getpass.getpass() can now be given an explicit stream

2520
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002521- email 4.0 package now integrated. This is largely the same as the email 3.0
2522 package that was included in Python 2.3, except that PEP 8 module names are
2523 now used (e.g. mail.message instead of email.Message). The MIME classes
2524 have been moved to a subpackage (e.g. email.mime.text instead of
2525 email.MIMEText). The old names are still supported for now. Several
2526 deprecated Message methods have been removed and lots of bugs have been
2527 fixed. More details can be found in the email package documentation.
2528
Walter Dörwald40108c92006-03-27 08:15:44 +00002529- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2530 (a subclass of tuple) that provides incremental decoders and encoders
2531 (a way to use stateful codecs without the stream API). Python functions
2532 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2533 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2534 have been added.

2537 a ValueError instead of a StopIteration now (like file and cString.String do).

2607
Neal Norwitz338e7862005-12-23 21:27:46 +00002608- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2609 LoadError as documented, instead of IOError. For compatibility,
2610 LoadError subclasses IOError.
2611
Brett Cannon3cbd0382005-12-16 22:49:23 +00002612- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002613 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2614 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2615 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2616 Ronald L. Rivest offered this advice for Python:
2617
2618 "The consensus of researchers in this area (at least as
2619 expressed at the NIST Hash Function Workshop 10/31/05),
2620 is that SHA-256 is a good choice for the time being, but
2621 that research should continue, and other alternatives may
2622 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002623
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002624- Added a subset of Fredrik Lundh's ElementTree package. Available

2677 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002678 correct line numbers for decoding errors in source code.

2701 to W3C name (404 -> 'Not Found'). RFE #1216944.
2702
Georg Brandl9e43acf2005-07-04 17:16:07 +00002703- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2704 as this can cause problems with apps closing all file descriptors.

2717 Bug #1224621.
2718
Raymond Hettinger68c04532005-06-10 11:05:19 +00002719- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002720 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002721 the generate_tokens() function now accepts a callable argument that
2722 terminates by raising StopIteration.
2723
Georg Brandl9166e1a2005-06-04 09:20:03 +00002724- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2728
Skip Montanaro174dd222005-05-14 20:54:16 +00002729- Patch #1120353: The xmlrpclib module provides better, more transparent,

2732 class at all.
2733
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002734- distutils.commands.upload was added to support uploading distribution

2738 them to PyPI.
2739
Raymond Hettinger267b8682005-03-27 10:47:39 +00002740- decimal operator and comparison methods now return NotImplemented
2741 instead of raising a TypeError when interacting with other types. This
2742 allows other classes to implement __radd__ style methods and have them
2743 work as expected.
2744
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002745- Bug #1163325: Decimal infinities failed to hash. Attempting to
2746 hash a NaN raised an InvalidOperation instead of a TypeError.
2747
Tim Petersecc6e6a2005-07-10 22:30:55 +00002748- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2782
Guido van Rossumd0641422005-02-03 15:01:24 +00002783- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2784 disables recursive traversal through instance attributes, which can
2785 be exploited in various ways.
2786
Tim Peterse3547fd2005-12-16 23:13:57 +00002787- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002788 flags on the HTTP listening socket.
2789
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002790- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2791 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2792
Fred Drakefbdeaad2006-07-29 16:56:15 +00002793- Patches #893642, #1039083: add allow_none, encoding arguments to
2794 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002795
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002796- Bug #1110478: Revert os.environ.update to do putenv again.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002798- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2799
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002800- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2801
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002802- Enhancements to the csv module:
2803
2804 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002805 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002806 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002807 + Dialect parameter parsing has been re-implemented to improve error
2808 reporting.
2809 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2810 dictates.
2811 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002812 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002813 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002814 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2815 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002816 + reader now allows \r characters to be quoted (previously it only allowed
2817 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002818 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002819 + Dialect classes passed to the module are no longer instantiated by
2820 the module before being parsed (the former validation scheme required
2821 this, but the mechanism was unreliable).
2822 + The dialect registry now contains instances of the internal
2823 C-coded dialect type, rather than references to python objects.
2824 + the internal c-coded dialect type is now immutable.
2825 + register_dialect now accepts the same keyword dialect specifications
2826 as the reader and writer, allowing the user to register dialects
2827 without first creating a dialect class.
2828 + a configurable limit to the size of parsed fields has been added -
2829 previously, an unmatched quote character could result in the entire
2830 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002831 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002832 the parser field size limit (returning the former limit). The initial
2833 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002834 + A line_num attribute has been added to the reader object, which tracks
2835 the number of lines read from the source iterator. This is not
2836 the same as the number of records returned, as records can span
2837 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002838 + reader and writer objects were not being registered with the cyclic-GC.
2839 This has been fixed.
2840
Brett Cannone6539c42005-01-08 02:43:53 +00002841- _DummyThread objects in the threading module now delete self.__block that is
2842 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2843 lock primitives tend to be limited in number and thus should not be wasted on
2844 a _DummyThread object. Fixes bug #1089632.
2845
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002846- The imghdr module now detects Exif files.
2847
Raymond Hettinger6065d322004-12-20 23:51:53 +00002848- StringIO.truncate() now correctly adjusts the size attribute.
2849 (Bug #951915).
2850
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002851- locale.py now uses an updated locale alias table (built using
2852 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2853 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002854 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002855
Raymond Hettinger3557f422004-12-07 12:02:02 +00002856- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2857
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002858- the pickle module no longer accepts the deprecated None option in the
2859 args tuple returned by __reduce__().
2860
Brett Cannon84667c02004-12-07 03:25:18 +00002861- optparse now optionally imports gettext. This allows its use in setup.py.
2862
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002863- the pickle module no longer uses the deprecated bin parameter.
2864
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002865- the shelve module no longer uses the deprecated binary parameter.
2866

2868
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002869- the filecmp module no longer uses the deprecated use_statcache argument.
2870
Raymond Hettinger664347b2004-12-04 21:21:53 +00002871- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2872 extended or overridden by subclasses. Formerly, the subclassed method would
2873 be ignored by the rest of the module. (Bug #1078905).
2874
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002875- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002876 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002877
Walter Dörwald36733692004-12-22 12:50:50 +00002878- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2879 once when a size argument is given. This prevents a buffer overflow in the
2880 tokenizer with very long source lines.
2881
Barry Warsaw538561e2006-01-01 21:48:54 +00002882- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2883 immediately after creating the object, without any intervening
2884 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002885
Skip Montanaro05885812005-01-16 20:48:27 +00002886- The reconvert.quote function can now emit triple-quoted strings. The
2887 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002888
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002889- ``UserString.MutableString`` now supports negative indices in
2890 ``__setitem__`` and ``__delitem__``
2891
Greg Ward40407942005-03-05 02:53:17 +00002892- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2893 correctly.
2894
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002895- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2896 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2897 character even if the user has passed a size parameter to get a proper
2898 line ending. Remove the special handling of a "\r\n" that has been split
2899 between two lines.
2900
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002901- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2902 about illegal code points. The codec now supports PEP 293 style error
2903 handlers.
2904
Walter Dörwald78a78b02005-09-01 12:04:29 +00002905- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002906 from the input stream, so that the output is a byte string in the correct
2907 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002908
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002909- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2910 considering it exactly like a '*'.
2911
Walter Dörwald007f8df2005-10-09 19:42:27 +00002912- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2913 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002914
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002915- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2916
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002917- Patch #1413711: Certain patterns of differences were making difflib
2918 touch the recursion limit.
2919
Walter Dörwald58917a62006-03-31 15:26:22 +00002920- Bug #947906: An object oriented interface has been added to the calendar
2921 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002922 called as a script (e.g. via ``python -mcalendar``). Localized month and
2923 weekday names can be ouput (even if an exotic encoding is used) using
2924 special classes that use unicode.

2927-----
2928
Neal Norwitz602d3392006-03-31 08:21:40 +00002929- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2930 by using -mieee gcc option.
2931

2933
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002934- Build support for Win64-AMD64 was added.
2935
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002936- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2937
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002938- Patch #881820: look for openpty and forkpty also in libbsd.
2939
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002940- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2941 The zlib module is now builtin on Windows.
2942
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002943- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2944
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002945- Bug #1189330: configure did not correctly determine the necessary
2946 value of LINKCC if python was built with GCC 4.0.
2947
Trent Mick8321b422005-07-26 02:29:21 +00002948- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2949 vulnerability in zlib 1.2.1 and 1.2.2.
2950
Brett Cannon08cd5982005-04-24 22:26:38 +00002951- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2952 flags that change binary compatibility. Changes were also made to
2953 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002954 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002955
Bob Ippolitoed233462005-03-29 13:47:59 +00002956- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2957 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2958 no longer exists). This configure patch makes things right.
2959
Martin v. Löwise2713be2005-03-08 15:03:08 +00002960- Bug #1158607: Build with --disable-unicode again.
2961
Brett Cannon46d96232005-02-16 00:07:19 +00002962- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2963 defined. Discovered as a result of not being able to build on OS X.
2964
Brett Cannon516592f2004-12-07 00:42:59 +00002965- setup.py now uses the directories specified in LDFLAGS using the -L option
2966 and in CPPFLAGS using the -I option for adding library and include
2967 directories, respectively, for compiling extension modules against. This has
2968 led to the core being compiled using the values in CPPFLAGS. It also removes
2969 the need for the special-casing of both DarwinPorts and Fink for darwin since
2970 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2971 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2972 Fink, ``-I/opt/local/include`` for DarwinPorts).
2973
Brett Cannon43802422005-02-10 20:48:03 +00002974- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2975 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2976 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2977 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002979C API
2980-----
2981
Tim Petersc9d78aa2006-03-26 23:27:58 +00002982- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2983 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2984 is obtained via the ``PyObject_`` family, it must be released via the
2985 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2986 always been officially true, but when Python's small-object allocator was
2987 introduced, an attempt was made to cater to a few extension modules
2988 discovered at the time that obtained memory via ``PyObject_New`` but
2989 released it via ``PyMem_DEL``. It's years later, and if such code still
2990 exists it will fail now (probably with segfaults, but calling wrong
2991 low-level memory management functions can yield many symptoms).
2992
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002993- Added a C API for set and frozenset objects.
2994
Raymond Hettinger66517482004-12-03 11:45:13 +00002995- Removed PyRange_New().
2996
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002997- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2998 mapping argument now. This string is used as a mapping table. Byte values
2999 greater than the length of the string and 0xFFFE are treated as undefined
3000 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003007
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003008- Patch #1276356: New resource "urlfetch" is implemented. This enables
3009 even impatient people to run tests that require remote files.
