Georg Brandld59ea472007-03-08 18:37:35 +0000576- unittest now verifies more of its assumptions. In particular, TestCase
577 and TestSuite subclasses (not instances) are no longer accepted in

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

Walter Dörwald93a36032007-04-21 10:31:43 +0000878- Fix utf-8-sig incremental decoder, which didn't recognise a BOM when the
879 first chunk fed to the decoder started with a BOM, but was longer than 3 bytes.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000930What's New in Python 2.5 release candidate 1?
931=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000932
Anthony Baxterb4096662006-08-16 03:42:26 +0000933*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000934
935Core and builtins
936-----------------
937
Neal Norwitz24b6f202006-09-05 04:43:56 +0000938- Fix infinite recursion when subclassing long and overriding __hash__.
939
940- Fix concatenation (+=) of long strings.
941
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000942- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000943 compared equal or unequal to a string and a UnicodeDecodeError
944 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000945
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000946 Instead, the equal (==) and unequal (!=) comparison operators will
947 now issue a UnicodeWarning and interpret the two objects as
948 unequal. The UnicodeWarning can be filtered as desired using
949 the warning framework, e.g. silenced completely, turned into an
950 exception, logged, etc.
951
952 Note that compare operators other than equal and unequal will still
953 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000954
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000955- Fix segfault when doing string formatting on subclasses of long.
956
957- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
958 with new-style classes.
959
960- Fix bug related to __len__ functions returning negative values with
961 classic classes.
962
963- Patch #1538606, Fix __index__() clipping. There were some problems
964 discovered with the API and how integers that didn't fit into Py_ssize_t
965 were handled. This patch attempts to provide enough alternatives
966 to effectively use __index__.
967
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000968- Bug #1536021: __hash__ may now return long int; the final hash
969 value is obtained by invoking hash on the long int.
970
Thomas Hellerab1049c2006-08-08 17:37:00 +0000971- Bug #1536786: buffer comparison could emit a RuntimeWarning.
972
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000973- Bug #1535165: fixed a segfault in input() and raw_input() when
974 sys.stdin is closed.
975
Thomas Heller74d36f02006-08-04 18:17:40 +0000976- On Windows, the PyErr_Warn function is now exported from
977 the Python dll again.
978
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000979- Bug #1191458: tracing over for loops now produces a line event
980 on each iteration. Fixing this problem required changing the .pyc
981 magic number. This means that .pyc files generated before 2.5c1
982 will be regenerated.
983
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000984- Bug #1333982: string/number constants were inappropriately stored
985 in the byte code and co_consts even if they were not used, ie
986 immediately popped off the stack.
987
Georg Brandle9462c72006-08-04 18:03:37 +0000988- Fixed a reference-counting problem in property().

991Library
992-------
993
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000994- Fix a bug in the ``compiler`` package that caused invalid code to be
995 generated for generator expressions.
996
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000997- The distutils version has been changed to 2.5.0. The change to
998 keep it programmatically in sync with the Python version running
999 the code (introduced in 2.5b3) has been reverted. It will continue
1000 to be maintained manually as static string literal.
1001
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001002- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001003 and this cannot be converted to the required C type, an exception is
1004 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001005 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001006
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001007- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001008 an exception.
1009
Tim Peterscbdd3502006-09-05 01:47:53 +00001010- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001011 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001012 workarounds for clocks with low resolution, to stop the code yielding
1013 duplicate UUIDs.
1014
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001015- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1016 before raising SystemExit, allowing IDLE to honor quit() and exit().
1017
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001018- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1019
Georg Brandl7a1af772006-08-14 21:55:28 +00001020- Patch #1536071: trace.py should now find the full module name of a
1021 file correctly even on Windows.
1022
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001023- logging's atexit hook now runs even if the rest of the module has
1024 already been cleaned up.
1025
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001026- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001027
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001028- Bug #1531405, format_exception no longer raises an exception if
1029 str(exception) raised an exception.
1030
Neil Schemenauer06ded092006-08-04 16:20:30 +00001031- Fix a bug in the ``compiler`` package that caused invalid code to be
1032 generated for nested functions.

1043 raises the correct exceptions.
1044
Thomas Heller1ce433e2006-08-14 16:20:04 +00001045- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1046 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1047
Thomas Heller86720042006-08-14 11:17:48 +00001048- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1049 uses the _as_parameter_ attribute when objects are passed to foreign
1050 function calls. The ctypes version number was changed to 1.0.1.
1051
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001052- Bug #1530559, struct.pack raises TypeError where it used to convert.
1053 Passing float arguments to struct.pack when integers are expected
1054 now triggers a DeprecationWarning.
1055
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001056

1100================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001101
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001102*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001103
1104Core and builtins
1105-----------------
1106
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001107- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001108 returned a long (see PEP 353).
1109
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001110- Bug #1515471: string.replace() accepts character buffers again.
1111
Neal Norwitz07aadb12006-07-30 06:55:48 +00001112- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1113 This provides the proper warning for struct.pack().
1114 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1115
Neal Norwitz0d62a062006-07-30 06:53:31 +00001116- Patch #1531113: Fix augmented assignment with yield expressions.
1117 Also fix a SystemError when trying to assign to yield expressions.
1118
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001119- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1120 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1121 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1122 excessive filesystem operations during imports.
1123
Tim Petersbc24eee2006-07-27 01:14:53 +00001124- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1125 operations on signed longs that are formally undefined by C.
1126 Unfortunately, at least one compiler now cares about that, so complicated
1127 the code to make that compiler happy again.
1128
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001129- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1130
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001131- Patch #1232023: Stop including current directory in search
1132 path on Windows.
1133
Neal Norwitze1fdb322006-07-21 05:32:28 +00001134- Fix some potential crashes found with failmalloc.
1135
Neal Norwitze7563102006-07-17 01:00:16 +00001136- Fix warnings reported by Klocwork's static analysis tool.
1137
Neal Norwitz84be93b2006-07-16 01:50:38 +00001138- Bug #1512814, Fix incorrect lineno's when code within a function
1139 had more than 255 blank lines.
1140
Georg Brandl9dceedb2006-07-12 15:31:17 +00001141- Patch #1521179: Python now accepts the standard options ``--help`` and
1142 ``--version`` as well as ``/?`` on Windows.
1143
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001144- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001145 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001146 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001147
Tim Peters112aad32006-07-19 00:03:19 +00001148- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001149 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001150 new ``sys._current_frames()`` returns a dictionary with one entry,
1151 mapping the faux "thread id" 0 to the current frame.
1152
Ronald Oussoren3075e162006-07-25 20:28:55 +00001153- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001154

1158
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001159- Correction of patch #1455898: In the mbcs decoder, set final=False
1160 for stream decoder, but final=True for the decode function.
1161
Georg Brandl07fec3a2006-08-01 18:49:24 +00001162- os.urandom no longer masks unrelated exceptions like SystemExit or
1163 KeyboardInterrupt.
1164
Tim Peters4643c2f2006-08-10 22:45:34 +00001165- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001166 shutil.copytree on Windows
1167
Georg Brandle34ac7c2006-07-30 11:07:23 +00001168- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1169 refers to file descriptors, not file objects.
1170
Tim Peterscbdd3502006-09-05 01:47:53 +00001171- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001172 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001173 #1513611, and probably others.
1174
Georg Brandledd9b0d2006-07-29 09:33:26 +00001175- Bug #1441397: The compiler module now recognizes module and function
1176 docstrings correctly as it did in Python 2.4.
1177
Tim Peters6f681472006-07-27 23:44:37 +00001178- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1179 lost that tests are sorted by name before being run. This rarely
1180 matters for well-written tests, but can create baffling symptoms if
1181 side effects from one test to the next affect outcomes. ``DocTestFinder``
1182 has been changed to sort the list of tests it returns.
1183
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001184- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001185 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001186
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001187- Bug #978833: Really close underlying socket in _socketobject.close.
1188
Georg Brandldb232dc2006-08-20 13:15:43 +00001189- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1190 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001191
Georg Brandlcf0c1722006-07-26 07:23:32 +00001192- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1193 to recursive calls and call it with the failing package name.
1194
Martin v. Löwis0b483032006-07-25 09:53:12 +00001195- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1196
Georg Brandlc13c34c2006-07-24 14:09:56 +00001197- Patch #1515343: Fix printing of deprecated string exceptions with a
1198 value in the traceback module.
1199
Greg Ward48fae7a2006-07-23 16:05:51 +00001200- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1201
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001202- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1203
Brett Cannoncaebe222006-07-18 04:41:36 +00001204- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1205 argument tuple. For arguments where zero is illegal, the value is forced to
1206 the minimum value that is correct. This is to support an undocumented but
1207 common way people used to fill in inconsequential information in the time
1208 tuple pre-2.4.
1209
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001210- Patch #1220874: Update the binhex module for Mach-O.
1211
Barry Warsawb110bad2006-07-21 14:51:07 +00001212- The email package has improved RFC 2231 support, specifically for
1213 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1214 (name*0=<blah>) parameter continuations. This may change the types of
1215 values returned from email.message.Message.get_param() and friends.
1216 Specifically in some cases where non-encoded continuations were used,
1217 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1218 will just return the string (since non-encoded continuations don't have
1219 charset and language parts).
1220
1221 Also, whereas % values were decoded in all parameter continuations, they are
1222 now only decoded in encoded parameter parts.
1223
Ronald Oussoren3075e162006-07-25 20:28:55 +00001224- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1225
1226- Bug #1517996: IDLE now longer shows the default Tk menu when a
1227 path browser, class browser or debugger is the frontmost window on MacOS X
1228
Barry Warsaw00decd72006-07-27 23:43:15 +00001229- Patch #1520294: Support for getset and member descriptors in types.py,
1230 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1231 of an object against these built-in types and more importantly, for getting
1232 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001235Extension Modules
1236-----------------
1237
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001238- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1239 a socket operation on a socket with a timeout, the exception will be
1240 caught correctly. Previously, the exception was not caught.
1241
Thomas Heller1393d6a2006-07-28 21:43:20 +00001242- Patch #1529514: The _ctypes extension is now compiled on more
1243 openbsd target platforms.
1244
Tim Peters9cab5932006-07-28 00:30:00 +00001245- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1246 a memory leak, affecting pickles and deep copies.
1247
Tim Petersbc24eee2006-07-27 01:14:53 +00001248- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001249 Paul Eggert.
1250
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001251- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1252
Thomas Hellerce049a02006-07-14 17:51:14 +00001253- Patch #1521817: Index range checking on ctypes arrays containing
1254 exactly one element enabled again. This allows iterating over these
1255 arrays, without the need to check the array size before.
1256
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001257- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001258 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001259 /dev/null in certain cases; this is now fixed.
1260
Thomas Heller47d7a062006-07-12 08:43:47 +00001261- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1262 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001263
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001264- Because of a misspelled preprocessor symbol, ctypes was always
1265 compiled without thread support; this is now fixed.
1266
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001267- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1268 methods now allow their database parameter to be None as the
1269 sleepycat API allows.
1270
Matt Flemingec926502006-07-28 11:27:27 +00001271- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1272 bluetooth API compared with Linux and FreeBSD.
1273
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001274Tests
1275-----
1276
1277- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1278 how long the test file should take to play. Now accepts taking 2.93 secs
1279 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1280
Georg Brandl4793aa32006-07-28 18:31:39 +00001281- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1282 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1283 run via ``regrtest.py``. Now they do.

1287
1288- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1289
Ronald Oussoren26cad082006-08-01 21:00:57 +00001290Mac
1291---
1292
1293- PythonLauncher now works correctly when the path to the script contains
1294 characters that are treated specially by the shell (such as quotes).
1295
1296- Bug #1527397: PythonLauncher now launches scripts with the working directory
1297 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001298 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001299 expect.

1308-----------------
1309
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001310- Bug #1441486: The literal representation of -(sys.maxint - 1)
1311 again evaluates to a int object, not a long.
1312
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001313- Bug #1501934: The scope of global variables that are locally assigned
1314 using augmented assignment is now correctly determined.
1315
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001316- Bug #927248: Recursive method-wrapper objects can now safely
1317 be released.
1318
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001319- Bug #1417699: Reject locale-specific decimal point in float()
1320 and atof().
1321
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001322- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1323 omit a default "error" argument for NULL pointer. This allows
1324 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001325
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001326- Bug #1519018: 'as' is now validated properly in import statements.
1327
Neal Norwitz28746ab2006-07-09 22:14:42 +00001328- On 64 bit systems, int literals that use less than 64 bits are
1329 now ints rather than longs.
1330
Neal Norwitzed657552006-07-10 00:04:44 +00001331- Bug #1512814, Fix incorrect lineno's when code at module scope
1332 started after line 256.
1333
Tim Peters32a83612006-07-10 21:08:24 +00001334- New function ``sys._current_frames()`` returns a dict mapping thread
1335 id to topmost thread stack frame. This is for expert use, and is
1336 especially useful for debugging application deadlocks. The functionality
1337 was previously available in Fazal Majid's ``threadframe`` extension
1338 module, but it wasn't possible to do this in a wholly threadsafe way from
1339 an extension.

1356
Thomas Woutersadd19112006-07-05 11:03:49 +00001357- string.Template() now correctly handles tuple-values. Previously,
1358 multi-value tuples would raise an exception and single-value tuples would
1359 be treated as the value they contain, instead.
1360
Martin v. Löwisede77f52006-07-03 13:01:35 +00001361- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1363
Martin v. Löwis45482392006-07-03 12:28:58 +00001364- Bug #1267547: Put proper recursive setup.py call into the

1366
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001367- Bug #1514693: Update turtle's heading when switching between
1368 degrees and radians.
1369
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001370- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001371 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001372
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001373- Bug #1514703: Only setup canvas window in turtle when the canvas
1374 is created.
1375
Martin v. Löwis7596e832006-07-01 15:33:37 +00001376- Bug #1513223: .close() of a _socketobj now releases the underlying
1377 socket again, which then gets closed as it becomes unreferenced.
1378
Fred Drake10497c82006-06-29 02:57:48 +00001379- Bug #1504333: Make sgmllib support angle brackets in quoted
1380 attribute values.
1381
1382- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1383 sgmllib ('[' and ']' were not accepted).
1384
Georg Brandl1be63af2006-06-28 20:23:25 +00001385- Fix a bug in the turtle module's end_fill function.
1386
Brett Cannon53ab5b72006-06-22 16:49:14 +00001387- Bug #1510580: The 'warnings' module improperly required that a Warning
1388 category be either a types.ClassType and a subclass of Warning. The proper
1389 check is just that it is a subclass with Warning as the documentation states.
1390
Georg Brandlad29e632006-06-21 17:45:17 +00001391- The compiler module now correctly compiles the new try-except-finally
1392 statement (bug #1509132).
1393
Neal Norwitz60373cd2006-06-22 06:30:50 +00001394- The wsgiref package is now installed properly on Unix.
1395
Vinay Sajip28e57612006-07-01 10:45:20 +00001396- A bug was fixed in logging.config.fileConfig() which caused a crash on
1397 shutdown when fileConfig() was called multiple times.
1398
Gerhard Häring762fbd32006-07-02 17:48:30 +00001399- The sqlite3 module did cut off data from the SQLite database at the first
1400 null character before sending it to a custom converter. This has been fixed
1401 now.
1402
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001403Extension Modules
1404-----------------
1405
Tim Peters112aad32006-07-19 00:03:19 +00001406- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1407 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1408 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001409
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001410- Assigning None to pointer type fields in ctypes structures possible
1411 overwrote the wrong fields, this is fixed now.
1412
1413- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1414 on non-Windows platforms.
1415
1416- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1417 integer or long, without range checking.
1418
1419- Patch #1517790: It is now possible to use custom objects in the ctypes
1420 foreign function argtypes sequence as long as they provide a from_param
1421 method, no longer is it required that the object is a ctypes type.
1422
1423- The '_ctypes' extension module now works when Python is configured
1424 with the --without-threads option.
1425
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001426- Bug #1513646: os.access on Windows now correctly determines write
1427 access, again.
1428
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001429- Bug #1512695: cPickle.loads could crash if it was interrupted with
1430 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001432- Bug #1296433: parsing XML with a non-default encoding and
1433 a CharacterDataHandler could crash the interpreter in pyexpat.
1434
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001435- Patch #1516912: improve Modules support for OpenVMS.

1441
Tim Peters32a83612006-07-10 21:08:24 +00001442- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001443 Previously, the slight difference could cause compilation errors of the
1444 'zlib' module on systems with more than one version of zlib.
1445
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001446- The MSI compileall step was fixed to also support a TARGETDIR
1447 with spaces in it.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001476
1477Core and builtins
1478-----------------
1479
Georg Brandla56b9152006-06-19 06:35:54 +00001480- Patch #1507676: Error messages returned by invalid abstract object operations
1481 (such as iterating over an integer) have been improved and now include the
1482 type of the offending object to help with debugging.
1483
Brett Cannonea3912b2006-06-13 21:46:41 +00001484- Bug #992017: A classic class that defined a __coerce__() method that returned
1485 its arguments swapped would infinitely recurse and segfault the interpreter.
1486
Neal Norwitz909eb122006-06-12 02:13:21 +00001487- Fix the socket tests so they can be run concurrently.
1488
Neal Norwitzb9845e72006-06-12 02:11:18 +00001489- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001490 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001491
Brett Cannon22565aa2006-06-09 22:31:23 +00001492- Bug #532646: object.__call__() will continue looking for the __call__
1493 attribute on objects until one without one is found. This leads to recursion
1494 when you take a class and set its __call__ attribute to an instance of the
1495 class. Originally fixed for classic classes, but this fix is for new-style.
1496 Removes the infinite_rec_3 crasher.
1497
Georg Brandl24250812006-06-09 18:45:48 +00001498- The string and unicode methods startswith() and endswith() now accept
1499 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1500
Brett Cannonde3b0522006-06-08 17:00:45 +00001501- Buffer objects, at the C level, never used the char buffer
1502 implementation even when the char buffer for the wrapped object was
1503 explicitly requested (originally returned the read or write buffer).
1504 Now a TypeError is raised if the char buffer is not present but is
1505 requested.
1506
Georg Brandlddbaa662006-06-04 21:56:52 +00001507- Patch #1346214: Statements like "if 0: suite" are now again optimized
1508 away like they were in Python 2.4.
1509
Georg Brandlb7c8f542006-05-27 12:30:25 +00001510- Builtin exceptions are now full-blown new-style classes instead of
1511 instances pretending to be classes, which speeds up exception handling
1512 by about 80% in comparison to 2.5a2.
1513
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001514- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1515 Unicode 4.1.
1516
Georg Brandlf4ef1162006-05-26 18:03:31 +00001517- Patch #921466: sys.path_importer_cache is now used to cache valid and
1518 invalid file paths for the built-in import machinery which leads to
1519 fewer open calls on startup.
1520
Tim Peters696cf432006-05-24 21:10:40 +00001521- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1522 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1523 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1524 the number of input digits (it was and remains linear-time for bases
1525 2, 4, 8, 16 and 32).
1526
Tim Petersb713ec22006-05-23 18:45:30 +00001527- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1528 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1529 an integer close to ``sys.maxint``. This was repaired by patch
1530 #1335972, which also gives a nice speedup.
1531
Richard Jonescebbefc2006-05-23 18:28:17 +00001532- Patch #1337051: reduced size of frame objects.
1533
1534- PyErr_NewException now accepts a tuple of base classes as its
1535 "base" parameter.
1536
Richard Jones7c88dcc2006-05-23 10:37:38 +00001537- Patch #876206: function call speedup by retaining allocated frame
1538 objects.
1539
Georg Brandl7b90e162006-05-18 07:01:27 +00001540- Bug #1462152: file() now checks more thoroughly for invalid mode
1541 strings and removes a possible "U" before passing the mode to the
1542 C library function.
1543
Neal Norwitz1004a532006-05-15 07:17:23 +00001544- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1545
Neal Norwitz373f0a72006-05-15 07:04:36 +00001546- Bug #1487966: Fix SystemError with conditional expression in assignment
1547
Martin v. Löwis879768d2006-05-11 13:28:43 +00001548- WindowsError now has two error code attributes: errno, which carries
1549 the error values from errno.h, and winerror, which carries the error
1550 values from winerror.h. Previous versions put the winerror.h values
1551 (from GetLastError()) into the errno attribute.
1552
Martin v. Löwis77736712006-05-04 05:51:03 +00001553- Patch #1475845: Raise IndentationError for unexpected indent.
1554
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001555- Patch #1479181: split open() and file() from being aliases for each other.
1556
Tim Peters44bd9862006-06-01 13:49:23 +00001557- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1558 methods were always silently ignored by dictionaries when comparing keys.
1559 They are now passed through (except when using the C API function
1560 ``PyDict_GetItem()``, whose semantics did not change).
1561
1562- Bug #1456209: In some obscure cases it was possible for a class with a
1563 custom ``__eq__()`` method to confuse dict internals when class instances
1564 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1565 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001567Extension Modules
1568-----------------
1569
Trent Mick960a3f82006-06-28 20:30:41 +00001570- Bug #1295808: expat symbols should be namespaced in pyexpat
1571
1572- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1573
Brett Cannon6ee7d012006-06-08 16:23:04 +00001574- Change binascii.hexlify to accept a read-only buffer instead of only a char
1575 buffer and actually follow its documentation.
1576
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001577- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1578
Nick Coghlanc649ec52006-05-29 12:43:05 +00001579- Patch #1478788 (modified version): The functional extension module has
1580 been renamed to _functools and a functools Python wrapper module added.
1581 This provides a home for additional function related utilities that are
1582 not specifically about functional programming. See PEP 309.
1583
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001584- Patch #1493701: performance enhancements for struct module.
1585
Georg Brandl378d5922006-05-17 14:26:50 +00001586- Patch #1490224: time.altzone is now set correctly on Cygwin.
1587
Georg Brandl8d3342b2006-05-16 07:38:27 +00001588- Patch #1435422: zlib's compress and decompress objects now have a
1589 copy() method.
1590
Andrew MacIntyre92913322006-06-13 15:04:24 +00001591- Patch #1454481: thread stack size is now tunable at runtime for thread
1592 enabled builds on Windows and systems with Posix threads support.
1593
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001594- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1595 (up to the system limit of 32K characters).
1596
1597- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1598 As a result, these functions now raise WindowsError instead of OSError.
1599
Tim Peters7a822da2006-05-25 21:50:17 +00001600- ``time.clock()`` on Win64 should use the high-performance Windows
1601 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1602 Windows platforms).
1603
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001604- Calling Tk_Init twice is refused if the first call failed as that
1605 may deadlock.
1606
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001607- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1608 accept it without potentially using an uninitialized pointer.
1609
1610- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1611 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1612 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001613
Gregory P. Smith372b5832006-06-05 18:48:21 +00001614- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001615 [pybsddb project SF patch number 1466734]
1616
Gregory P. Smith372b5832006-06-05 18:48:21 +00001617- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1618 parameter is supplied. [SF pybsddb bug #1477863]
1619
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001620- bsddb: the __len__ method of a DB object has been fixed to return correct
1621 results. It could previously incorrectly return 0 in some cases.
1622 Fixes SF bug 1493322 (pybsddb bug 1184012).
1623
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001624- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1625 aborts the db transaction safely when a modifier callback fails.
1626 Fixes SF python patch/bug #1408584.
1627
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001628- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001629 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001630 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1631 database calls that would previously deadlock. [SF python bug #775414]
1632
Vinay Sajip28e57612006-07-01 10:45:20 +00001633- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001634
Walter Dörwald4994d952006-06-19 08:07:50 +00001635- Patch #1506645: add Python wrappers for the curses functions
1636 is_term_resized, resize_term and resizeterm.

1639-------
1640
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001641- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1642 functions.
1643
Martin v. Löwis3798da02006-06-17 18:44:27 +00001644- Patch #812986: Update turtle output even if not tracing.
1645
Vinay Sajip28e57612006-07-01 10:45:20 +00001646- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001647 Tkinter.BaseWidget.
1648
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001649- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1650
Martin v. Löwis337487e2006-06-17 09:15:14 +00001651- Patch #763580: Add name and value arguments to Tkinter variable
1652 classes.
1653
Georg Brandl83cc0d02006-06-14 08:50:03 +00001654- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1655 mime.types file for determining MIME types.
1656
Georg Brandl2605ca82006-06-14 06:08:31 +00001657- Bug #1339007: Shelf objects now don't raise an exception in their
1658 __del__ method when initialization failed.
1659
Martin v. Löwisd8251432006-06-14 05:21:04 +00001660- Patch #1455898: The MBCS codec now supports the incremental mode for
1661 double-byte encodings.
1662
Tim Peters43898b42006-06-14 04:09:25 +00001663- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1664 guarantee that adjacent triples in the return list always describe
1665 non-adjacent blocks. Previously, a pair of matching blocks could end
1666 up being described by multiple adjacent triples that formed a partition
1667 of the matching pair.
1668
Greg Ward0e0c9f42006-06-11 16:24:11 +00001669- Bug #1498146: fix optparse to handle Unicode strings in option help,
1670 description, and epilog.
1671
Greg Wardd1c797e2006-06-11 14:42:41 +00001672- Bug #1366250: minor optparse documentation error.
1673
Greg Ward7f547402006-06-11 00:40:49 +00001674- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1675 clarify docs.
1676
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001677- The wsgiref package has been added to the standard library.
1678
Nick Coghlan676725d2006-06-08 13:54:49 +00001679- The functions update_wrapper() and wraps() have been added to the functools
1680 module. These make it easier to copy relevant metadata from the original
1681 function when writing wrapper functions.
1682
Tim Petersd6a9eef2006-06-05 01:48:21 +00001683- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1684 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001685
Martin v. Löwis3f767792006-06-04 19:36:28 +00001686- Patch #1359618: Speed up charmap encoder by using a trie structure
1687 for lookup.
1688
Tim Petersd609b1a2006-06-02 23:22:51 +00001689- The functions in the ``pprint`` module now sort dictionaries by key
1690 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1691 if and only if its display required more than one line, although that
1692 wasn't documented. The new behavior increases predictability; e.g.,
1693 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1694
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001695- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1696 (thanks for J. J. Lee).
1697
Georg Brandl2b330372006-05-28 20:23:12 +00001698- Patch #1496206: improve urllib2 handling of passwords with respect to
1699 default HTTP and HTTPS ports.
1700
George Yoshidaf3c65de2006-05-28 16:39:09 +00001701- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1702
Bob Ippolito7298f272006-05-23 18:43:47 +00001703- Patch #1281707: speed up gzip.readline.
1704
Georg Brandlb89316f2006-05-17 15:51:16 +00001705- Patch #1180296: Two new functions were added to the locale module:
1706 format_string() to get the effect of "format % items" but locale-aware,
1707 and currency() to format a monetary number with currency sign.
1708
Georg Brandle3a25832006-05-17 14:56:04 +00001709- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1710 and several features added, such as speed and geometry control.
1711
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001712- Patch #1488881: add support for external file objects in bz2 compressed
1713 tarfiles.
1714
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001715- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1716 stdout arguments, making it possible to redirect input and output
1717 for remote debugging.
1718
1719- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1720 a couple of issues, notably handling of long file names using the
1721 GNU LONGNAME extension.
1722
1723- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1724 new flag when ``name`` is already the name of an option flag.
1725
1726- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1727 package.
1728
1729- Patch #1472854: make the rlcompleter.Completer class usable on non-
1730 UNIX platforms.
1731
1732- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1733
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001734- Bug #1472827: correctly escape newlines and tabs in attribute values in
1735 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001765What's New in Python 2.5 alpha 2?
1766=================================
1767
1768*Release date: 27-APR-2006*
1769
1770Core and builtins
1771-----------------
1772
Thomas Heller1b046642006-04-18 18:51:06 +00001773- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1774 by converting these apis from macros into exported functions again:
1775
1776 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1777 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1778 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1779 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1780 PyRun_String Py_CompileString
1781
Martin v. Löwis45294a92006-04-18 06:24:08 +00001782- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1783
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001784- All uses of PyStructSequence_InitType have been changed to initialize
1785 the type objects only once, even if the interpreter is initialized
1786 multiple times.
1787
Neal Norwitz61546162006-04-14 05:20:28 +00001788- Bug #1454485, array.array('u') could crash the interpreter. This was
1789 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1790 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1791
1792- Py_UNICODE is unsigned. It was always documented as unsigned, but
1793 due to a bug had a signed value in previous versions.
1794
Tim Peters3a5e8b12006-04-11 01:44:07 +00001795- Patch #837242: ``id()`` of any Python object always gives a positive
1796 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1797 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001798 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001799 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001800
Tim Peters3a5e8b12006-04-11 01:44:07 +00001801 def __hash__(self):
1802 return id(self) # WRONG
1803
1804 because a hash result must be a (short) Python int but it was always
1805 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001806 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001807 was always usable as a hash value before this patch. That's no longer
1808 necessarily so.
1809
1810- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001811 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001812 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001813 #1454844)
1814
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001815- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1816 involving generators that have paused outside of any ``try`` or ``with``
1817 blocks. (In 2.5a1, a paused generator that was part of a reference
1818 cycle could not be garbage collected, regardless of whether it was
1819 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001820
Anthony Baxter51bcb682006-04-05 14:51:42 +00001821Extension Modules
1822-----------------
1823
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001824- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1825 is a macro.
1826
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001827- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1828 fails with an error condition.
1829
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001830- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1831
1832- Bug #1117761: bsddb.*open() no longer raises an exception when using
1833 the cachesize parameter.
1834
1835- Bug #1149413: bsddb.*open() no longer raises an exception when using
1836 a temporary db (file=None) with the 'n' flag to truncate on open.
1837
1838- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1839 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001840
Armin Rigoa9017c32006-04-19 11:50:27 +00001841- Patch #1062014: AF_UNIX sockets under Linux have a special
1842 abstract namespace that is now fully supported.
1843
Anthony Baxter51bcb682006-04-05 14:51:42 +00001844Library
1845-------
1846
Peter Astrand7d1d4362006-07-14 14:04:45 +00001847- Bug #1223937: subprocess.CalledProcessError reports the exit status
1848 of the process using the returncode attribute, instead of
1849 abusing errno.
1850
Tim Peters711bf302006-04-25 03:31:36 +00001851- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1852 a doctest to be skipped (the code is not run, and the expected output
1853 or exception is ignored).
1854
Nick Coghlanda2268f2006-04-24 04:37:15 +00001855- Fixed contextlib.nested to cope with exceptions being raised and
1856 caught inside exit handlers.
1857
Greg Wardab05edc2006-04-23 03:47:58 +00001858- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1859 hex, octal, or binary; add ``append_const`` action; keep going if
1860 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1861 added ``epilog`` for better help generation).
1862
Tim Peters21fbd572006-04-21 21:18:10 +00001863- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1864 called from a thread spawned as a side effect of importing a module.
1865
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001866- The pydoc module now supports documenting packages contained in
1867 .zip or .egg files.
1868
1869- The pkgutil module now has several new utility functions, such
1870 as ``walk_packages()`` to support working with packages that are either
1871 in the filesystem or zip files.
1872
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001873- The mailbox module can now modify and delete messages from
1874 mailboxes, in addition to simply reading them. Thanks to Gregory
1875 K. Johnson for writing the code, and to the 2005 Google Summer of
1876 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001877
Tim Petersc7605f22006-04-17 21:12:33 +00001878- The ``__del__`` method of class ``local`` in module ``_threading_local``
1879 returned before accomplishing any of its intended cleanup.
1880
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001881- Patch #790710: Add breakpoint command lists in pdb.
1882
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001883- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1884
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001885- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1886
Anthony Baxtere29002c2006-04-12 12:07:31 +00001887- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1888 Windows. Bug #1469163.
1889
Phillip J. Eby47032112006-04-11 01:07:43 +00001890- The warnings, linecache, inspect, traceback, site, and doctest modules
1891 were updated to work correctly with modules imported from zipfiles or
1892 via other PEP 302 __loader__ objects.
1893
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001894- Patch #1467770: Reduce usage of subprocess._active to processes which
1895 the application hasn't waited on.
1896
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001897- Patch #1462222: Fix Tix.Grid.
1898
Neal Norwitza31bf182006-04-09 03:35:43 +00001899- Fix exception when doing glob.glob('anything*/')
1900
Skip Montanaro262fb922006-04-21 02:31:07 +00001901- The pstats.Stats class accepts an optional stream keyword argument to
1902 direct output to an alternate file-like object.
1903
Anthony Baxter51bcb682006-04-05 14:51:42 +00001904Build
1905-----
1906
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001907- The Makefile now has a reindent target, which runs reindent.py on
1908 the library.
1909
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001910- Patch #1470875: Building Python with MS Free Compiler
1911
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001912- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001913
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001914- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1915 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001916 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001917 CXX from --with-cxx-main, see description in README.
1918
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001919- Patch #1429775: Link extension modules with the shared libpython.
1920
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001921- Fixed a libffi build problem on MIPS systems.
1922
Tim Peters8931ff12006-05-13 23:28:20 +00001923- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1924 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1925 and "%zu" for unsigned integers of type ``size_t``.
1926
Anthony Baxter51bcb682006-04-05 14:51:42 +00001927Tests
1928-----
1929
Nick Coghlanda2268f2006-04-24 04:37:15 +00001930- test_contextlib now checks contextlib.nested can cope with exceptions
1931 being raised and caught inside exit handlers.
1932
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001933- test_cmd_line now checks operation of the -m and -c command switches
1934
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001935- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1936 it separately and by hand. It also wasn't cleaning up its changes to
1937 the current Decimal context.
1938
Thomas Woutersabd08882006-04-26 15:53:30 +00001939- regrtest.py now has a -M option to run tests that test the new limits of
1940 containers, on 64-bit architectures. Running these tests is only sensible
1941 on 64-bit machines with more than two gigabytes of memory. The argument
1942 passed is the maximum amount of memory for the tests to use.
1943
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001944Tools
1945-----
1946
1947- Added the Python benchmark suite pybench to the Tools/ directory;
1948 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001949
Anthony Baxter51bcb682006-04-05 14:51:42 +00001950Documentation
1951-------------
1952
Tim Petersb06d28c2006-05-12 01:57:59 +00001953- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1954
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001955- PEP 343: Added Context Types section to the library reference
1956 and attempted to bring other PEP 343 related documentation into
1957 line with the implementation and/or python-dev discussions.
1958
Tim Peters8dc73d22006-04-24 02:03:16 +00001959- Bug #1337990: clarified that ``doctest`` does not support examples
1960 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001961
1962
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001963What's New in Python 2.5 alpha 1?
1964=================================
1965
Anthony Baxterebed3f62006-04-03 15:03:44 +00001966*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001967
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001968Core and builtins
1969-----------------
1970
Nick Coghlan43832302006-04-23 17:04:07 +00001971- PEP 338: -m command line switch now delegates to runpy.run_module
1972 allowing it to support modules in packages and zipfiles
1973
Martin v. Löwisc661b882006-04-20 04:54:23 +00001974- On Windows, .DLL is not an accepted file name extension for
1975 extension modules anymore; extensions are only found if they
1976 end in .PYD.
1977
Martin v. Löwisea62d252006-04-03 10:56:49 +00001978- Bug #1421664: sys.stderr.encoding is now set to the same value as
1979 sys.stdout.encoding.
1980
Neal Norwitz92e212f2006-04-03 04:48:37 +00001981- __import__ accepts keyword arguments.
1982
Georg Brandlccadf842006-03-31 18:54:53 +00001983- Patch #1460496: round() now accepts keyword arguments.
1984
Anthony Baxter262c00a2006-03-30 10:53:17 +00001985- Fixed bug #1459029 - unicode reprs were double-escaped.
1986
Hye-Shik Changd478f342006-03-23 12:32:36 +00001987- Patch #1396919: The system scope threads are reenabled on FreeBSD
1988 5.4 and later versions.
1989
Neal Norwitze98ccf62006-03-23 05:39:47 +00001990- Bug #1115379: Compiling a Unicode string with an encoding declaration
1991 now gives a SyntaxError.
1992
Georg Brandlabd1ff82006-03-18 07:59:59 +00001993- Previously, Python code had no easy way to access the contents of a
1994 cell object. Now, a ``cell_contents`` attribute has been added
1995 (closes patch #1170323).
1996
Tim Peterscf79aac2006-03-16 01:14:46 +00001997- Patch #1123430: Python's small-object allocator now returns an arena to
1998 the system ``free()`` when all memory within an arena becomes unused
1999 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2000 freed. Some applications will see a drop in virtual memory size now,
2001 especially long-running applications that, from time to time, temporarily
2002 use a large number of small objects. Note that when Python returns an
2003 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002004 platform C library will in turn return that memory to the operating system.
2005 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002006 appears to be effective at least on Microsoft C and gcc-based systems.
2007 Thanks to Evan Jones for hard work and patience.
2008
Georg Brandl533ff6f2006-03-08 18:09:27 +00002009- Patch #1434038: property() now uses the getter's docstring if there is
2010 no "doc" argument given. This makes it possible to legitimately use
2011 property() as a decorator to produce a read-only property.
2012
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002013- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2014 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2015 of requiring an int or long in slicing and a few other contexts, enabling
2016 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2017
Neal Norwitz995acdf2006-03-07 05:01:00 +00002018- Fixed various bugs reported by Coverity's Prevent tool.
2019
Brett Cannonbf364092006-03-01 04:25:17 +00002020- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2021 new exception base class, BaseException, which has a new message attribute.
2022 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2023 Raising a string exception now raises a DeprecationWarning.
2024
Thomas Woutersfb609f42006-02-28 16:37:25 +00002025- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2026 explicitly relative, using 'from .module import name' to mean 'from the same
2027 package as this module is in. Imports without dots still default to the
2028 old relative-then-absolute, unless 'from __future__ import
2029 absolute_import' is used.
2030
Brett Cannona7446e32006-02-27 23:39:10 +00002031- Properly check if 'warnings' raises an exception (usually when a filter set
2032 to "error" is triggered) when raising a warning for raising string
2033 exceptions.
2034
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002035- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002036 The name was removed from Include/code.h.
2037
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002038- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002039
Guido van Rossum1968ad32006-02-25 22:38:04 +00002040- Patch 1433928:
2041 - The copy module now "copies" function objects (as atomic objects).
2042 - dict.__getitem__ now looks for a __missing__ hook before raising
2043 KeyError.
2044
Tim Peters84ef21c2006-02-28 20:39:06 +00002045- PEP 343: with statement implemented. Needs ``from __future__ import
2046 with_statement``. Use of 'with' as a variable will generate a warning.
2047 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002048 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002049 The following objects have __context__ methods:
2050 - The built-in file type.
2051 - The thread.LockType type.
2052 - The following types defined by the threading module:
2053 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2054 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002055
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002056- Fix the encodings package codec search function to only search
2057 inside its own package. Fixes problem reported in patch #1433198.
2058
2059 Note: Codec packages should implement and register their own
2060 codec search function. PEP 100 has the details.
2061
Tim Peters9ea89d22006-06-04 03:26:02 +00002062- PEP 353: Using ``Py_ssize_t`` as the index type.
2063
2064- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2065 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2066 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2067 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2068 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002069
Neal Norwitzfc76d632006-01-10 06:03:13 +00002070- Patch #1400181, fix unicode string formatting to not use the locale.
2071 This is how string objects work. u'%f' could use , instead of .
2072 for the decimal point. Now both strings and unicode always use periods.
2073
Neal Norwitz671b9e32006-01-09 07:07:12 +00002074- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2075 configure would break checking curses.h.
2076
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002077- Bug #959576: The pwd module is now builtin. This allows Python to be
2078 built on UNIX platforms without $HOME set.
2079
Neal Norwitzc10978f2005-12-19 06:07:16 +00002080- Bug #1072182, fix some potential problems if characters are signed.
2081
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002082- Bug #889500, fix line number on SyntaxWarning for global declarations.
2083
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002084- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2085
Neal Norwitze7214a12005-12-18 05:03:17 +00002086- Support for converting hex strings to floats no longer works.
2087 This was not portable. float('0x3') now raises a ValueError.
2088
Barry Warsaw2a38a862005-12-18 01:27:35 +00002089- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002090 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002091 is now displayed in interactive prompt banner.
2092
Georg Brandlfa166682005-12-17 21:45:17 +00002093- Implementation of PEP 341 - Unification of try/except and try/finally.
2094 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002095 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002096
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002097- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2098 now encodes backslash correctly.
2099
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002100- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2101
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002102- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002103 and long longs.
2104
Neal Norwitz67715f02005-11-09 06:59:35 +00002105- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002106 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002107 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002108
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002109- Replaced most Unicode charmap codecs with new ones using the
2110 new Unicode translate string feature in the builtin charmap
2111 codec; the codecs were created from the mapping tables available
2112 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2113 encodings now include a mapping for the Apple logo)
2114
Tim Peterse3547fd2005-12-16 23:13:57 +00002115- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002116
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002117- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002118
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002119- A new AST parser implementation was completed. The abstract
2120 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002121 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002122
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002123- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002124 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2125
Neal Norwitz708e51a2005-10-03 04:48:15 +00002126- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2127
Neal Norwitz11bd1192005-10-03 00:54:56 +00002128- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2129 Provide a warning when a directory is passed on the command line.
2130
Neal Norwitz40d37812005-10-02 01:48:49 +00002131- Fix segfault with invalid coding.
2132
2133- SF bug #772896: unknown encoding results in MemoryError.
2134
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002135- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002136 supported a __len__() method which evaluated to False when the iterator
2137 was empty.
2138
Guido van Rossum630db602005-09-20 18:49:54 +00002139- On 64-bit platforms, when __len__() returns a value that cannot be
2140 represented as a C int, raise OverflowError.
2141
Skip Montanarof8948ca2005-09-19 03:54:46 +00002142- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002143 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002144
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002145- SF bug #893549: parsing keyword arguments was broken with a few format
2146 codes.
2147
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002148- Changes donated by Elemental Security to make it work on AIX 5.3
2149 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2150 bug #105470: test_pwd fails on 64bit system (Opteron).
2151
Guido van Rossum539c6622005-09-14 17:49:54 +00002152- Changes donated by Elemental Security to make it work on HP-UX 11 on
2153 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2154
Georg Brandl4550b8d2005-08-26 06:43:52 +00002155- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002156 (fixes bug #1119418).
2157
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002158- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2159
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002160- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2161 exceptions that cause a function to exit.
2162
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002163- The implementation of set() and frozenset() was revised to use its
2164 own internal data structure. Memory consumption is reduced by 1/3
2165 and there are modest speed-ups as well. The API is unchanged.
2166
Tim Petersde7990b2005-07-17 23:45:23 +00002167- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2168
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002169- SF bug #1229429: PyObject_CallMethod failed to decrement some
2170 reference counts in some error exit cases.
2171
Tim Petersecc6e6a2005-07-10 22:30:55 +00002172- SF bug #1185883: Python's small-object memory allocator took over
2173 a block managed by the platform C library whenever a realloc specified
2174 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002175 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002176 portable way to copy data from the C-managed block into Python's
2177 small-object space without risking a memory fault. Python's small-object
2178 realloc now leaves such blocks under the control of the platform C
2179 realloc.
2180
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002181- SF bug #1232517: An overflow error was not detected properly when
2182 attempting to convert a large float to an int in os.utime().
2183
Raymond Hettinger3296e692005-06-29 23:29:56 +00002184- SF bug #1224347: hex longs now print with lowercase letters just
2185 like their int counterparts.
2186
Michael W. Hudson188d4362005-06-20 16:52:57 +00002187- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2188 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2189 interpreter states; back out that fix and do a better job (see
2190 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2191 for a longer write-up of the problem).
2192
Michael W. Hudsondf888462005-06-03 14:41:55 +00002193- SF patch #1180995: marshal now uses a binary format by default when
2194 serializing floats.
2195
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002196- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2197 the routines that promise to produce IEEE 754 binary representations
2198 of floats now simply copy bytes around.
2199
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002200- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2201 278.
2202
Brett Cannonc3647ac2005-04-26 03:45:26 +00002203- patch #1109424: int, long, float, complex, and unicode now check for the
2204 proper magic slot for type conversions when subclassed. Previously the
2205 magic slot was ignored during conversion. Semantics now match the way
2206 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002207 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002208 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002209 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002210
Barry Warsawc8d907c2005-04-19 23:43:40 +00002211- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2212 NULL, now raise an AttributeError when attempting to set or delete the
2213 attribute. Previously a TypeError was raised, but this was inconsistent
2214 with the equivalent pure-Python implementation.
2215
Michael W. Hudson774479c2005-04-18 08:46:17 +00002216- It is now safe to call PyGILState_Release() before
2217 PyEval_InitThreads() (note that if there is reason to believe there
2218 are multiple threads around you still must call PyEval_InitThreads()
2219 before using the Python API; this fix is for extension modules that
2220 have no way of knowing if Python is multi-threaded yet).
2221
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002222- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2223 disabled caused a crash.
2224
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002225- Bug #1165306: instancemethod_new allowed the creation of a method
2226 with im_class == im_self == NULL, which caused a crash when called.
2227
Tim Petersecc6e6a2005-07-10 22:30:55 +00002228- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002229 fixes the crash seen in bug #1165761
2230
Raymond Hettinger96229b12005-03-11 06:49:40 +00002231- Added two new builtins, any() and all().
2232
Brett Cannon409d8f22005-03-05 06:47:57 +00002233- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002234 (e.g., ``class C(): pass`` is no longer a syntax error).
2235 Patch #1176012 added support to the 'parser' module and 'compiler' package
2236 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002237
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002238- Patch #1115086: Support PY_LONGLONG in structmember.
2239
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002240- Bug #1155938: new style classes did not check that __init__() was
2241 returning None.
2242
Tim Petersecc6e6a2005-07-10 22:30:55 +00002243- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002244 ('\') with a specific error message.
2245
Martin v. Löwisff232d72005-03-03 09:24:38 +00002246- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2247
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002248- Bug #1124295: the __name__ attribute of file objects was
2249 inadvertently made inaccessible in restricted mode.
2250
Tim Petersecc6e6a2005-07-10 22:30:55 +00002251- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002252 an ferror() call.
2253
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002254- min() and max() now support key= arguments with the same meaning as in
2255 list.sort().
2256
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002257- The peephole optimizer now performs simple constant folding in expressions:
2258 (2+3) --> (5).
2259
Raymond Hettingera422c342005-01-11 03:03:27 +00002260- set and frozenset objects can now be marshalled. SF #1098985.
2261
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002262- Bug #1077106: Poor argument checking could cause memory corruption
2263 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002264
Jeremy Hyltonab630502005-02-04 18:44:06 +00002265- The parser did not complain about future statements in illegal
2266 positions. It once again reports a syntax error if a future
2267 statement occurs after anything other than a doc string.
2268
Neil Schemenauercf52c072005-08-12 17:34:58 +00002269- Change the %s format specifier for str objects so that it returns a
2270 unicode instance if the argument is not an instance of basestring and
2271 calling __str__ on the argument returns a unicode instance.
2272
Tim Petersf4e69282006-02-27 17:15:31 +00002273- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2274 current thread state when the auto-GIL-state machinery knows about
2275 it (since the thread state is being deleted, continuing to remember it
2276 can't help, but can hurt if another thread happens to get created with
2277 the same thread id).
2278
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002279Extension Modules
2280-----------------
2281
Georg Brandl43f08a82006-03-31 18:01:16 +00002282- Patch #1380952: fix SSL objects timing out on consecutive read()s
2283
Neal Norwitz05a45592006-03-20 06:30:08 +00002284- Patch #1309579: wait3 and wait4 were added to the posix module.
2285
Anthony Baxterfa869072006-03-20 05:21:58 +00002286- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2287 In addition, the existing ulaw code was updated.
2288
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002289- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002290 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002291
Neal Norwitz10be10c2006-03-16 06:50:13 +00002292- Everything under lib-old was removed. This includes the following modules:
2293 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002294 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002295 util, whatsound, whrandom, zmod
2296
2297- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2298
2299- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002300 is deprecated. The undocumented re.engine variable no longer exists.
2301
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002302- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2303 SS2 (single-shift 2) escape sequences correctly.
2304
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002305- The unicodedata module was updated to the 4.1 version of the Unicode
2306 database. The 3.2 version is still available as unicodedata.db_3_2_0
2307 for applications that require this specific version (such as IDNA).
2308
Neal Norwitzb62c4332006-03-04 18:35:47 +00002309- The timing module is no longer built by default. It was deprecated
2310 in PEP 4 in Python 2.0 or earlier.
2311
Guido van Rossum1968ad32006-02-25 22:38:04 +00002312- Patch 1433928: Added a new type, defaultdict, to the collections module.
2313 This uses the new __missing__ hook behavior added to dict (see above).
2314
Georg Brandldbd83392006-02-20 09:42:33 +00002315- Bug #854823: socketmodule now builds on Sun platforms even when
2316 INET_ADDRSTRLEN is not defined.
2317
Georg Brandlf4f44152006-02-18 22:29:33 +00002318- Patch #1393157: os.startfile() now has an optional argument to specify

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002469- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2470 been renamed to have only a single underscore prefix. This was done to
2471 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002472
Nick Coghlan43832302006-04-23 17:04:07 +00002473- PEP 338: new module runpy defines a run_module function to support
2474 executing modules which provide access to source code or a code object
2475 via the PEP 302 import mechanisms.
2476
Anthony Baxter93f5b932006-04-03 08:05:07 +00002477- The email module's parsedate_tz function now sets the daylight savings

2485 in attribute values.
2486
Anthony Baxterc51ee692006-04-01 00:57:31 +00002487- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002488 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002489 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002490 module will not be built.
2491
Tim Petersc17976e2006-04-01 00:26:53 +00002492- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2493 aren't officially supported here, and trying to use them will probably
2494 raise an exception some day. But dicts have been allowed, and "mostly
2495 worked", so support for them won't go away without warning.
2496
Georg Brandl338ef7d2006-03-31 18:42:16 +00002497- Bug #1445068: getpass.getpass() can now be given an explicit stream

2515
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002516- email 4.0 package now integrated. This is largely the same as the email 3.0
2517 package that was included in Python 2.3, except that PEP 8 module names are
2518 now used (e.g. mail.message instead of email.Message). The MIME classes
2519 have been moved to a subpackage (e.g. email.mime.text instead of
2520 email.MIMEText). The old names are still supported for now. Several
2521 deprecated Message methods have been removed and lots of bugs have been
2522 fixed. More details can be found in the email package documentation.
2523
Walter Dörwald40108c92006-03-27 08:15:44 +00002524- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2525 (a subclass of tuple) that provides incremental decoders and encoders
2526 (a way to use stateful codecs without the stream API). Python functions
2527 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2528 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2529 have been added.

2532 a ValueError instead of a StopIteration now (like file and cString.String do).

2602
Neal Norwitz338e7862005-12-23 21:27:46 +00002603- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2604 LoadError as documented, instead of IOError. For compatibility,
2605 LoadError subclasses IOError.
2606
Brett Cannon3cbd0382005-12-16 22:49:23 +00002607- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002608 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2609 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2610 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2611 Ronald L. Rivest offered this advice for Python:
2612
2613 "The consensus of researchers in this area (at least as
2614 expressed at the NIST Hash Function Workshop 10/31/05),
2615 is that SHA-256 is a good choice for the time being, but
2616 that research should continue, and other alternatives may
2617 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002618
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002619- Added a subset of Fredrik Lundh's ElementTree package. Available

2672 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002673 correct line numbers for decoding errors in source code.

2696 to W3C name (404 -> 'Not Found'). RFE #1216944.
2697
Georg Brandl9e43acf2005-07-04 17:16:07 +00002698- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2699 as this can cause problems with apps closing all file descriptors.

2712 Bug #1224621.
2713
Raymond Hettinger68c04532005-06-10 11:05:19 +00002714- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002715 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002716 the generate_tokens() function now accepts a callable argument that
2717 terminates by raising StopIteration.
2718
Georg Brandl9166e1a2005-06-04 09:20:03 +00002719- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2723
Skip Montanaro174dd222005-05-14 20:54:16 +00002724- Patch #1120353: The xmlrpclib module provides better, more transparent,

2727 class at all.
2728
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002729- distutils.commands.upload was added to support uploading distribution

2733 them to PyPI.
2734
Raymond Hettinger267b8682005-03-27 10:47:39 +00002735- decimal operator and comparison methods now return NotImplemented
2736 instead of raising a TypeError when interacting with other types. This
2737 allows other classes to implement __radd__ style methods and have them
2738 work as expected.
2739
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002740- Bug #1163325: Decimal infinities failed to hash. Attempting to
2741 hash a NaN raised an InvalidOperation instead of a TypeError.
2742
Tim Petersecc6e6a2005-07-10 22:30:55 +00002743- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2777
Guido van Rossumd0641422005-02-03 15:01:24 +00002778- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2779 disables recursive traversal through instance attributes, which can
2780 be exploited in various ways.
2781
Tim Peterse3547fd2005-12-16 23:13:57 +00002782- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002783 flags on the HTTP listening socket.
2784
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002785- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2786 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2787
Fred Drakefbdeaad2006-07-29 16:56:15 +00002788- Patches #893642, #1039083: add allow_none, encoding arguments to
2789 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002790

2794
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002795- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2796
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002797- Enhancements to the csv module:
2798
2799 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002800 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002801 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002802 + Dialect parameter parsing has been re-implemented to improve error
2803 reporting.
2804 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2805 dictates.
2806 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002807 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002808 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002809 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2810 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002811 + reader now allows \r characters to be quoted (previously it only allowed
2812 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002813 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002814 + Dialect classes passed to the module are no longer instantiated by
2815 the module before being parsed (the former validation scheme required
2816 this, but the mechanism was unreliable).
2817 + The dialect registry now contains instances of the internal
2818 C-coded dialect type, rather than references to python objects.
2819 + the internal c-coded dialect type is now immutable.
2820 + register_dialect now accepts the same keyword dialect specifications
2821 as the reader and writer, allowing the user to register dialects
2822 without first creating a dialect class.
2823 + a configurable limit to the size of parsed fields has been added -
2824 previously, an unmatched quote character could result in the entire
2825 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002826 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002827 the parser field size limit (returning the former limit). The initial
2828 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002829 + A line_num attribute has been added to the reader object, which tracks
2830 the number of lines read from the source iterator. This is not
2831 the same as the number of records returned, as records can span
2832 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002833 + reader and writer objects were not being registered with the cyclic-GC.
2834 This has been fixed.
2835
Brett Cannone6539c42005-01-08 02:43:53 +00002836- _DummyThread objects in the threading module now delete self.__block that is
2837 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2838 lock primitives tend to be limited in number and thus should not be wasted on
2839 a _DummyThread object. Fixes bug #1089632.
2840
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002841- The imghdr module now detects Exif files.
2842
Raymond Hettinger6065d322004-12-20 23:51:53 +00002843- StringIO.truncate() now correctly adjusts the size attribute.
2844 (Bug #951915).
2845
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002846- locale.py now uses an updated locale alias table (built using
2847 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2848 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002849 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002850
Raymond Hettinger3557f422004-12-07 12:02:02 +00002851- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2852
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002853- the pickle module no longer accepts the deprecated None option in the
2854 args tuple returned by __reduce__().
2855
Brett Cannon84667c02004-12-07 03:25:18 +00002856- optparse now optionally imports gettext. This allows its use in setup.py.
2857
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002858- the pickle module no longer uses the deprecated bin parameter.
2859
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002860- the shelve module no longer uses the deprecated binary parameter.
2861
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002862- the pstats module no longer uses the deprecated ignore() method.
2863
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002864- the filecmp module no longer uses the deprecated use_statcache argument.
2865
Raymond Hettinger664347b2004-12-04 21:21:53 +00002866- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2867 extended or overridden by subclasses. Formerly, the subclassed method would
2868 be ignored by the rest of the module. (Bug #1078905).
2869
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002870- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002871 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002872
Walter Dörwald36733692004-12-22 12:50:50 +00002873- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2874 once when a size argument is given. This prevents a buffer overflow in the
2875 tokenizer with very long source lines.
2876
Barry Warsaw538561e2006-01-01 21:48:54 +00002877- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2878 immediately after creating the object, without any intervening
2879 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002880
Skip Montanaro05885812005-01-16 20:48:27 +00002881- The reconvert.quote function can now emit triple-quoted strings. The
2882 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002883
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002884- ``UserString.MutableString`` now supports negative indices in
2885 ``__setitem__`` and ``__delitem__``
2886
Greg Ward40407942005-03-05 02:53:17 +00002887- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2888 correctly.
2889
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002890- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2891 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2892 character even if the user has passed a size parameter to get a proper
2893 line ending. Remove the special handling of a "\r\n" that has been split
2894 between two lines.
2895
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002896- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2897 about illegal code points. The codec now supports PEP 293 style error
2898 handlers.
2899
Walter Dörwald78a78b02005-09-01 12:04:29 +00002900- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002901 from the input stream, so that the output is a byte string in the correct
2902 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002903
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002904- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2905 considering it exactly like a '*'.
2906
Walter Dörwald007f8df2005-10-09 19:42:27 +00002907- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2908 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002909
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002910- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2911
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002912- Patch #1413711: Certain patterns of differences were making difflib
2913 touch the recursion limit.
2914
Walter Dörwald58917a62006-03-31 15:26:22 +00002915- Bug #947906: An object oriented interface has been added to the calendar
2916 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002917 called as a script (e.g. via ``python -mcalendar``). Localized month and
2918 weekday names can be ouput (even if an exotic encoding is used) using
2919 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002921Build
2922-----
2923
Neal Norwitz602d3392006-03-31 08:21:40 +00002924- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2925 by using -mieee gcc option.
2926

2928
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002929- Build support for Win64-AMD64 was added.
2930
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002931- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2932
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002933- Patch #881820: look for openpty and forkpty also in libbsd.
2934
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002935- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2936 The zlib module is now builtin on Windows.
2937
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002938- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2939
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002940- Bug #1189330: configure did not correctly determine the necessary
2941 value of LINKCC if python was built with GCC 4.0.
2942
Trent Mick8321b422005-07-26 02:29:21 +00002943- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2944 vulnerability in zlib 1.2.1 and 1.2.2.
2945
Brett Cannon08cd5982005-04-24 22:26:38 +00002946- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2947 flags that change binary compatibility. Changes were also made to
2948 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002949 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002950
Bob Ippolitoed233462005-03-29 13:47:59 +00002951- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2952 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2953 no longer exists). This configure patch makes things right.
2954
Martin v. Löwise2713be2005-03-08 15:03:08 +00002955- Bug #1158607: Build with --disable-unicode again.
2956
Brett Cannon46d96232005-02-16 00:07:19 +00002957- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2958 defined. Discovered as a result of not being able to build on OS X.
2959
Brett Cannon516592f2004-12-07 00:42:59 +00002960- setup.py now uses the directories specified in LDFLAGS using the -L option
2961 and in CPPFLAGS using the -I option for adding library and include
2962 directories, respectively, for compiling extension modules against. This has
2963 led to the core being compiled using the values in CPPFLAGS. It also removes
2964 the need for the special-casing of both DarwinPorts and Fink for darwin since
2965 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2966 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2967 Fink, ``-I/opt/local/include`` for DarwinPorts).
2968
Brett Cannon43802422005-02-10 20:48:03 +00002969- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2970 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2971 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2972 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002974C API
2975-----
2976
Tim Petersc9d78aa2006-03-26 23:27:58 +00002977- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2978 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2979 is obtained via the ``PyObject_`` family, it must be released via the
2980 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2981 always been officially true, but when Python's small-object allocator was
2982 introduced, an attempt was made to cater to a few extension modules
2983 discovered at the time that obtained memory via ``PyObject_New`` but
2984 released it via ``PyMem_DEL``. It's years later, and if such code still
2985 exists it will fail now (probably with segfaults, but calling wrong
2986 low-level memory management functions can yield many symptoms).
2987
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002988- Added a C API for set and frozenset objects.
2989
Raymond Hettinger66517482004-12-03 11:45:13 +00002990- Removed PyRange_New().
2991
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002992- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2993 mapping argument now. This string is used as a mapping table. Byte values
2994 greater than the length of the string and 0xFFFE are treated as undefined
2995 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003002
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003003- Patch #1276356: New resource "urlfetch" is implemented. This enables
