Thomas Heller8bf469d2007-03-09 20:48:57 +0000582- Bug #1651235: When a tuple was passed to a ctypes function call,
583 Python would crash instead of raising an error.

591
Georg Brandld59ea472007-03-08 18:37:35 +0000592- unittest now verifies more of its assumptions. In particular, TestCase
593 and TestSuite subclasses (not instances) are no longer accepted in
594 TestSuite.addTest(). This should cause no incompatibility since it
595 never made sense with ordinary subclasses -- the failure just occurred
596 later, with a more cumbersome exception.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000950
951Core and builtins
952-----------------
953
Neal Norwitz24b6f202006-09-05 04:43:56 +0000954- Fix infinite recursion when subclassing long and overriding __hash__.
955
956- Fix concatenation (+=) of long strings.
957
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000958- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000959 compared equal or unequal to a string and a UnicodeDecodeError
960 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000961
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000962 Instead, the equal (==) and unequal (!=) comparison operators will
963 now issue a UnicodeWarning and interpret the two objects as
964 unequal. The UnicodeWarning can be filtered as desired using
965 the warning framework, e.g. silenced completely, turned into an
966 exception, logged, etc.
967
968 Note that compare operators other than equal and unequal will still
969 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000970
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000971- Fix segfault when doing string formatting on subclasses of long.
972
973- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
974 with new-style classes.
975
976- Fix bug related to __len__ functions returning negative values with
977 classic classes.
978
979- Patch #1538606, Fix __index__() clipping. There were some problems
980 discovered with the API and how integers that didn't fit into Py_ssize_t
981 were handled. This patch attempts to provide enough alternatives
982 to effectively use __index__.
983
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000984- Bug #1536021: __hash__ may now return long int; the final hash
985 value is obtained by invoking hash on the long int.
986
Thomas Hellerab1049c2006-08-08 17:37:00 +0000987- Bug #1536786: buffer comparison could emit a RuntimeWarning.
988
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000989- Bug #1535165: fixed a segfault in input() and raw_input() when
990 sys.stdin is closed.
991
Thomas Heller74d36f02006-08-04 18:17:40 +0000992- On Windows, the PyErr_Warn function is now exported from
993 the Python dll again.
994
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000995- Bug #1191458: tracing over for loops now produces a line event
996 on each iteration. Fixing this problem required changing the .pyc
997 magic number. This means that .pyc files generated before 2.5c1
998 will be regenerated.
999
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001000- Bug #1333982: string/number constants were inappropriately stored
1001 in the byte code and co_consts even if they were not used, ie
1002 immediately popped off the stack.
1003
Georg Brandle9462c72006-08-04 18:03:37 +00001004- Fixed a reference-counting problem in property().

1007Library
1008-------
1009
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001010- Fix a bug in the ``compiler`` package that caused invalid code to be
1011 generated for generator expressions.
1012
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001013- The distutils version has been changed to 2.5.0. The change to
1014 keep it programmatically in sync with the Python version running
1015 the code (introduced in 2.5b3) has been reverted. It will continue
1016 to be maintained manually as static string literal.
1017
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001018- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001019 and this cannot be converted to the required C type, an exception is
1020 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001021 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001022
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001023- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001024 an exception.
1025
Tim Peterscbdd3502006-09-05 01:47:53 +00001026- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001027 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001028 workarounds for clocks with low resolution, to stop the code yielding
1029 duplicate UUIDs.
1030
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001031- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1032 before raising SystemExit, allowing IDLE to honor quit() and exit().
1033
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001034- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1035
Georg Brandl7a1af772006-08-14 21:55:28 +00001036- Patch #1536071: trace.py should now find the full module name of a
1037 file correctly even on Windows.
1038
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001039- logging's atexit hook now runs even if the rest of the module has
1040 already been cleaned up.
1041
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001042- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001043
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001044- Bug #1531405, format_exception no longer raises an exception if
1045 str(exception) raised an exception.
1046
Neil Schemenauer06ded092006-08-04 16:20:30 +00001047- Fix a bug in the ``compiler`` package that caused invalid code to be
1048 generated for nested functions.

1059 raises the correct exceptions.
1060
Thomas Heller1ce433e2006-08-14 16:20:04 +00001061- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1062 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1063
Thomas Heller86720042006-08-14 11:17:48 +00001064- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1065 uses the _as_parameter_ attribute when objects are passed to foreign
1066 function calls. The ctypes version number was changed to 1.0.1.
1067
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001068- Bug #1530559, struct.pack raises TypeError where it used to convert.
1069 Passing float arguments to struct.pack when integers are expected
1070 now triggers a DeprecationWarning.

1120Core and builtins
1121-----------------
1122
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001123- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001124 returned a long (see PEP 353).
1125
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001126- Bug #1515471: string.replace() accepts character buffers again.
1127
Neal Norwitz07aadb12006-07-30 06:55:48 +00001128- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1129 This provides the proper warning for struct.pack().
1130 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1131
Neal Norwitz0d62a062006-07-30 06:53:31 +00001132- Patch #1531113: Fix augmented assignment with yield expressions.
1133 Also fix a SystemError when trying to assign to yield expressions.
1134
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001135- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1136 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1137 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1138 excessive filesystem operations during imports.
1139
Tim Petersbc24eee2006-07-27 01:14:53 +00001140- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1141 operations on signed longs that are formally undefined by C.
1142 Unfortunately, at least one compiler now cares about that, so complicated
1143 the code to make that compiler happy again.
1144
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001145- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1146
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001147- Patch #1232023: Stop including current directory in search
1148 path on Windows.
1149
Neal Norwitze1fdb322006-07-21 05:32:28 +00001150- Fix some potential crashes found with failmalloc.
1151
Neal Norwitze7563102006-07-17 01:00:16 +00001152- Fix warnings reported by Klocwork's static analysis tool.
1153
Neal Norwitz84be93b2006-07-16 01:50:38 +00001154- Bug #1512814, Fix incorrect lineno's when code within a function
1155 had more than 255 blank lines.
1156
Georg Brandl9dceedb2006-07-12 15:31:17 +00001157- Patch #1521179: Python now accepts the standard options ``--help`` and
1158 ``--version`` as well as ``/?`` on Windows.
1159
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001160- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001161 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001162 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001163
Tim Peters112aad32006-07-19 00:03:19 +00001164- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001165 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001166 new ``sys._current_frames()`` returns a dictionary with one entry,
1167 mapping the faux "thread id" 0 to the current frame.
1168
Ronald Oussoren3075e162006-07-25 20:28:55 +00001169- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001170

1174
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001175- Correction of patch #1455898: In the mbcs decoder, set final=False
1176 for stream decoder, but final=True for the decode function.
1177
Georg Brandl07fec3a2006-08-01 18:49:24 +00001178- os.urandom no longer masks unrelated exceptions like SystemExit or
1179 KeyboardInterrupt.
1180
Tim Peters4643c2f2006-08-10 22:45:34 +00001181- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001182 shutil.copytree on Windows
1183
Georg Brandle34ac7c2006-07-30 11:07:23 +00001184- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1185 refers to file descriptors, not file objects.
1186
Tim Peterscbdd3502006-09-05 01:47:53 +00001187- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001188 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001189 #1513611, and probably others.
1190
Georg Brandledd9b0d2006-07-29 09:33:26 +00001191- Bug #1441397: The compiler module now recognizes module and function
1192 docstrings correctly as it did in Python 2.4.
1193
Tim Peters6f681472006-07-27 23:44:37 +00001194- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1195 lost that tests are sorted by name before being run. This rarely
1196 matters for well-written tests, but can create baffling symptoms if
1197 side effects from one test to the next affect outcomes. ``DocTestFinder``
1198 has been changed to sort the list of tests it returns.
1199
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001200- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001201 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001202
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001203- Bug #978833: Really close underlying socket in _socketobject.close.
1204
Georg Brandldb232dc2006-08-20 13:15:43 +00001205- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1206 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001207
Georg Brandlcf0c1722006-07-26 07:23:32 +00001208- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1209 to recursive calls and call it with the failing package name.
1210
Martin v. Löwis0b483032006-07-25 09:53:12 +00001211- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1212
Georg Brandlc13c34c2006-07-24 14:09:56 +00001213- Patch #1515343: Fix printing of deprecated string exceptions with a
1214 value in the traceback module.
1215
Greg Ward48fae7a2006-07-23 16:05:51 +00001216- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1217
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001218- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1219
Brett Cannoncaebe222006-07-18 04:41:36 +00001220- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1221 argument tuple. For arguments where zero is illegal, the value is forced to
1222 the minimum value that is correct. This is to support an undocumented but
1223 common way people used to fill in inconsequential information in the time
1224 tuple pre-2.4.
1225
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001226- Patch #1220874: Update the binhex module for Mach-O.
1227
Barry Warsawb110bad2006-07-21 14:51:07 +00001228- The email package has improved RFC 2231 support, specifically for
1229 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1230 (name*0=<blah>) parameter continuations. This may change the types of
1231 values returned from email.message.Message.get_param() and friends.
1232 Specifically in some cases where non-encoded continuations were used,
1233 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1234 will just return the string (since non-encoded continuations don't have
1235 charset and language parts).
1236
1237 Also, whereas % values were decoded in all parameter continuations, they are
1238 now only decoded in encoded parameter parts.
1239
Ronald Oussoren3075e162006-07-25 20:28:55 +00001240- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1241
1242- Bug #1517996: IDLE now longer shows the default Tk menu when a
1243 path browser, class browser or debugger is the frontmost window on MacOS X
1244
Barry Warsaw00decd72006-07-27 23:43:15 +00001245- Patch #1520294: Support for getset and member descriptors in types.py,
1246 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1247 of an object against these built-in types and more importantly, for getting
1248 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001251Extension Modules
1252-----------------
1253
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001254- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1255 a socket operation on a socket with a timeout, the exception will be
1256 caught correctly. Previously, the exception was not caught.
1257
Thomas Heller1393d6a2006-07-28 21:43:20 +00001258- Patch #1529514: The _ctypes extension is now compiled on more
1259 openbsd target platforms.
1260
Tim Peters9cab5932006-07-28 00:30:00 +00001261- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1262 a memory leak, affecting pickles and deep copies.
1263
Tim Petersbc24eee2006-07-27 01:14:53 +00001264- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001265 Paul Eggert.
1266
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001267- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1268
Thomas Hellerce049a02006-07-14 17:51:14 +00001269- Patch #1521817: Index range checking on ctypes arrays containing
1270 exactly one element enabled again. This allows iterating over these
1271 arrays, without the need to check the array size before.
1272
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001273- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001274 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001275 /dev/null in certain cases; this is now fixed.
1276
Thomas Heller47d7a062006-07-12 08:43:47 +00001277- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1278 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001279
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001280- Because of a misspelled preprocessor symbol, ctypes was always
1281 compiled without thread support; this is now fixed.
1282
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001283- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1284 methods now allow their database parameter to be None as the
1285 sleepycat API allows.
1286
Matt Flemingec926502006-07-28 11:27:27 +00001287- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1288 bluetooth API compared with Linux and FreeBSD.
1289
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001290Tests
1291-----
1292
1293- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1294 how long the test file should take to play. Now accepts taking 2.93 secs
1295 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1296
Georg Brandl4793aa32006-07-28 18:31:39 +00001297- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1298 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1299 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001306Mac
1307---
1308
1309- PythonLauncher now works correctly when the path to the script contains
1310 characters that are treated specially by the shell (such as quotes).
1311
1312- Bug #1527397: PythonLauncher now launches scripts with the working directory
1313 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001314 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001315 expect.

1324-----------------
1325
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001326- Bug #1441486: The literal representation of -(sys.maxint - 1)
1327 again evaluates to a int object, not a long.
1328
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001329- Bug #1501934: The scope of global variables that are locally assigned
1330 using augmented assignment is now correctly determined.
1331
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001332- Bug #927248: Recursive method-wrapper objects can now safely
1333 be released.
1334
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001335- Bug #1417699: Reject locale-specific decimal point in float()
1336 and atof().
1337
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001338- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1339 omit a default "error" argument for NULL pointer. This allows
1340 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001341
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001342- Bug #1519018: 'as' is now validated properly in import statements.
1343
Neal Norwitz28746ab2006-07-09 22:14:42 +00001344- On 64 bit systems, int literals that use less than 64 bits are
1345 now ints rather than longs.
1346
Neal Norwitzed657552006-07-10 00:04:44 +00001347- Bug #1512814, Fix incorrect lineno's when code at module scope
1348 started after line 256.
1349
Tim Peters32a83612006-07-10 21:08:24 +00001350- New function ``sys._current_frames()`` returns a dict mapping thread
1351 id to topmost thread stack frame. This is for expert use, and is
1352 especially useful for debugging application deadlocks. The functionality
1353 was previously available in Fazal Majid's ``threadframe`` extension
1354 module, but it wasn't possible to do this in a wholly threadsafe way from
1355 an extension.

1361 VS 2003.
1362
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001363- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1364

Martin v. Löwis8d656812006-07-10 07:23:48 +00001366 environment variable to be set in order to the SDK environment
1367 for finding the compiler, include files, etc.

1372
Thomas Woutersadd19112006-07-05 11:03:49 +00001373- string.Template() now correctly handles tuple-values. Previously,
1374 multi-value tuples would raise an exception and single-value tuples would
1375 be treated as the value they contain, instead.
1376
Martin v. Löwisede77f52006-07-03 13:01:35 +00001377- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1378 even if some data are received.
1379
Martin v. Löwis45482392006-07-03 12:28:58 +00001380- Bug #1267547: Put proper recursive setup.py call into the
1381 spec file generated by bdist_rpm.
1382
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001383- Bug #1514693: Update turtle's heading when switching between
1384 degrees and radians.
1385
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001386- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001387 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001388
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001389- Bug #1514703: Only setup canvas window in turtle when the canvas
1390 is created.
1391
Martin v. Löwis7596e832006-07-01 15:33:37 +00001392- Bug #1513223: .close() of a _socketobj now releases the underlying
1393 socket again, which then gets closed as it becomes unreferenced.
1394
Fred Drake10497c82006-06-29 02:57:48 +00001395- Bug #1504333: Make sgmllib support angle brackets in quoted
1396 attribute values.
1397
1398- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1399 sgmllib ('[' and ']' were not accepted).
1400
Georg Brandl1be63af2006-06-28 20:23:25 +00001401- Fix a bug in the turtle module's end_fill function.
1402
Brett Cannon53ab5b72006-06-22 16:49:14 +00001403- Bug #1510580: The 'warnings' module improperly required that a Warning
1404 category be either a types.ClassType and a subclass of Warning. The proper
1405 check is just that it is a subclass with Warning as the documentation states.
1406
Georg Brandlad29e632006-06-21 17:45:17 +00001407- The compiler module now correctly compiles the new try-except-finally
1408 statement (bug #1509132).
1409
Neal Norwitz60373cd2006-06-22 06:30:50 +00001410- The wsgiref package is now installed properly on Unix.
1411
Vinay Sajip28e57612006-07-01 10:45:20 +00001412- A bug was fixed in logging.config.fileConfig() which caused a crash on
1413 shutdown when fileConfig() was called multiple times.
1414
Gerhard Häring762fbd32006-07-02 17:48:30 +00001415- The sqlite3 module did cut off data from the SQLite database at the first
1416 null character before sending it to a custom converter. This has been fixed
1417 now.

1420-----------------
1421
Tim Peters112aad32006-07-19 00:03:19 +00001422- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1423 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1424 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001425
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001426- Assigning None to pointer type fields in ctypes structures possible
1427 overwrote the wrong fields, this is fixed now.
1428
1429- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1430 on non-Windows platforms.
1431
1432- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1433 integer or long, without range checking.
1434
1435- Patch #1517790: It is now possible to use custom objects in the ctypes
1436 foreign function argtypes sequence as long as they provide a from_param
1437 method, no longer is it required that the object is a ctypes type.
1438
1439- The '_ctypes' extension module now works when Python is configured
1440 with the --without-threads option.
1441
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001442- Bug #1513646: os.access on Windows now correctly determines write
1443 access, again.
1444
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001445- Bug #1512695: cPickle.loads could crash if it was interrupted with
1446 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001448- Bug #1296433: parsing XML with a non-default encoding and
1449 a CharacterDataHandler could crash the interpreter in pyexpat.
1450
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001451- Patch #1516912: improve Modules support for OpenVMS.

1457
Tim Peters32a83612006-07-10 21:08:24 +00001458- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001459 Previously, the slight difference could cause compilation errors of the
1460 'zlib' module on systems with more than one version of zlib.
1461
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001462- The MSI compileall step was fixed to also support a TARGETDIR
1463 with spaces in it.
1464
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001465- Bug #1517388: sqlite3.dll is now installed on Windows independent

Anthony Baxter51bcb682006-04-05 14:51:42 +00001492
1493Core and builtins
1494-----------------
1495
Georg Brandla56b9152006-06-19 06:35:54 +00001496- Patch #1507676: Error messages returned by invalid abstract object operations
1497 (such as iterating over an integer) have been improved and now include the
1498 type of the offending object to help with debugging.
1499
Brett Cannonea3912b2006-06-13 21:46:41 +00001500- Bug #992017: A classic class that defined a __coerce__() method that returned
1501 its arguments swapped would infinitely recurse and segfault the interpreter.
1502
Neal Norwitz909eb122006-06-12 02:13:21 +00001503- Fix the socket tests so they can be run concurrently.
1504
Neal Norwitzb9845e72006-06-12 02:11:18 +00001505- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001506 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001507
Brett Cannon22565aa2006-06-09 22:31:23 +00001508- Bug #532646: object.__call__() will continue looking for the __call__
1509 attribute on objects until one without one is found. This leads to recursion
1510 when you take a class and set its __call__ attribute to an instance of the
1511 class. Originally fixed for classic classes, but this fix is for new-style.
1512 Removes the infinite_rec_3 crasher.
1513
Georg Brandl24250812006-06-09 18:45:48 +00001514- The string and unicode methods startswith() and endswith() now accept
1515 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1516
Brett Cannonde3b0522006-06-08 17:00:45 +00001517- Buffer objects, at the C level, never used the char buffer
1518 implementation even when the char buffer for the wrapped object was
1519 explicitly requested (originally returned the read or write buffer).
1520 Now a TypeError is raised if the char buffer is not present but is
1521 requested.
1522
Georg Brandlddbaa662006-06-04 21:56:52 +00001523- Patch #1346214: Statements like "if 0: suite" are now again optimized
1524 away like they were in Python 2.4.
1525
Georg Brandlb7c8f542006-05-27 12:30:25 +00001526- Builtin exceptions are now full-blown new-style classes instead of
1527 instances pretending to be classes, which speeds up exception handling
1528 by about 80% in comparison to 2.5a2.
1529
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001530- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1531 Unicode 4.1.
1532
Georg Brandlf4ef1162006-05-26 18:03:31 +00001533- Patch #921466: sys.path_importer_cache is now used to cache valid and
1534 invalid file paths for the built-in import machinery which leads to
1535 fewer open calls on startup.
1536
Tim Peters696cf432006-05-24 21:10:40 +00001537- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1538 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1539 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1540 the number of input digits (it was and remains linear-time for bases
1541 2, 4, 8, 16 and 32).
1542
Tim Petersb713ec22006-05-23 18:45:30 +00001543- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1544 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1545 an integer close to ``sys.maxint``. This was repaired by patch
1546 #1335972, which also gives a nice speedup.
1547
Richard Jonescebbefc2006-05-23 18:28:17 +00001548- Patch #1337051: reduced size of frame objects.
1549
1550- PyErr_NewException now accepts a tuple of base classes as its
1551 "base" parameter.
1552
Richard Jones7c88dcc2006-05-23 10:37:38 +00001553- Patch #876206: function call speedup by retaining allocated frame
1554 objects.
1555
Georg Brandl7b90e162006-05-18 07:01:27 +00001556- Bug #1462152: file() now checks more thoroughly for invalid mode
1557 strings and removes a possible "U" before passing the mode to the
1558 C library function.
1559
Neal Norwitz1004a532006-05-15 07:17:23 +00001560- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1561
Neal Norwitz373f0a72006-05-15 07:04:36 +00001562- Bug #1487966: Fix SystemError with conditional expression in assignment
1563
Martin v. Löwis879768d2006-05-11 13:28:43 +00001564- WindowsError now has two error code attributes: errno, which carries
1565 the error values from errno.h, and winerror, which carries the error
1566 values from winerror.h. Previous versions put the winerror.h values
1567 (from GetLastError()) into the errno attribute.
1568
Martin v. Löwis77736712006-05-04 05:51:03 +00001569- Patch #1475845: Raise IndentationError for unexpected indent.
1570
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001571- Patch #1479181: split open() and file() from being aliases for each other.
1572
Tim Peters44bd9862006-06-01 13:49:23 +00001573- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1574 methods were always silently ignored by dictionaries when comparing keys.
1575 They are now passed through (except when using the C API function
1576 ``PyDict_GetItem()``, whose semantics did not change).
1577
1578- Bug #1456209: In some obscure cases it was possible for a class with a
1579 custom ``__eq__()`` method to confuse dict internals when class instances
1580 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1581 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001583Extension Modules
1584-----------------
1585
Trent Mick960a3f82006-06-28 20:30:41 +00001586- Bug #1295808: expat symbols should be namespaced in pyexpat
1587
1588- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1589
Brett Cannon6ee7d012006-06-08 16:23:04 +00001590- Change binascii.hexlify to accept a read-only buffer instead of only a char
1591 buffer and actually follow its documentation.
1592
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001593- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1594
Nick Coghlanc649ec52006-05-29 12:43:05 +00001595- Patch #1478788 (modified version): The functional extension module has
1596 been renamed to _functools and a functools Python wrapper module added.
1597 This provides a home for additional function related utilities that are
1598 not specifically about functional programming. See PEP 309.
1599
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001600- Patch #1493701: performance enhancements for struct module.
1601
Georg Brandl378d5922006-05-17 14:26:50 +00001602- Patch #1490224: time.altzone is now set correctly on Cygwin.
1603
Georg Brandl8d3342b2006-05-16 07:38:27 +00001604- Patch #1435422: zlib's compress and decompress objects now have a
1605 copy() method.
1606
Andrew MacIntyre92913322006-06-13 15:04:24 +00001607- Patch #1454481: thread stack size is now tunable at runtime for thread
1608 enabled builds on Windows and systems with Posix threads support.
1609
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001610- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1611 (up to the system limit of 32K characters).
1612
1613- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1614 As a result, these functions now raise WindowsError instead of OSError.
1615
Tim Peters7a822da2006-05-25 21:50:17 +00001616- ``time.clock()`` on Win64 should use the high-performance Windows
1617 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1618 Windows platforms).
1619
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001620- Calling Tk_Init twice is refused if the first call failed as that
1621 may deadlock.
1622
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001623- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1624 accept it without potentially using an uninitialized pointer.
1625
1626- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1627 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1628 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001629
Gregory P. Smith372b5832006-06-05 18:48:21 +00001630- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001631 [pybsddb project SF patch number 1466734]
1632
Gregory P. Smith372b5832006-06-05 18:48:21 +00001633- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1634 parameter is supplied. [SF pybsddb bug #1477863]
1635
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001636- bsddb: the __len__ method of a DB object has been fixed to return correct
1637 results. It could previously incorrectly return 0 in some cases.
1638 Fixes SF bug 1493322 (pybsddb bug 1184012).
1639
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001640- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1641 aborts the db transaction safely when a modifier callback fails.
1642 Fixes SF python patch/bug #1408584.
1643
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001644- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001645 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001646 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1647 database calls that would previously deadlock. [SF python bug #775414]
1648
Vinay Sajip28e57612006-07-01 10:45:20 +00001649- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1656
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001657- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1658 functions.
1659
Martin v. Löwis3798da02006-06-17 18:44:27 +00001660- Patch #812986: Update turtle output even if not tracing.
1661
Vinay Sajip28e57612006-07-01 10:45:20 +00001662- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001663 Tkinter.BaseWidget.
1664
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001665- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1666
Martin v. Löwis337487e2006-06-17 09:15:14 +00001667- Patch #763580: Add name and value arguments to Tkinter variable
1668 classes.
1669
Georg Brandl83cc0d02006-06-14 08:50:03 +00001670- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1671 mime.types file for determining MIME types.
1672
Georg Brandl2605ca82006-06-14 06:08:31 +00001673- Bug #1339007: Shelf objects now don't raise an exception in their
1674 __del__ method when initialization failed.
1675
Martin v. Löwisd8251432006-06-14 05:21:04 +00001676- Patch #1455898: The MBCS codec now supports the incremental mode for
1677 double-byte encodings.
1678
Tim Peters43898b42006-06-14 04:09:25 +00001679- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1680 guarantee that adjacent triples in the return list always describe
1681 non-adjacent blocks. Previously, a pair of matching blocks could end
1682 up being described by multiple adjacent triples that formed a partition
1683 of the matching pair.
1684
Greg Ward0e0c9f42006-06-11 16:24:11 +00001685- Bug #1498146: fix optparse to handle Unicode strings in option help,
1686 description, and epilog.
1687
Greg Wardd1c797e2006-06-11 14:42:41 +00001688- Bug #1366250: minor optparse documentation error.
1689
Greg Ward7f547402006-06-11 00:40:49 +00001690- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1691 clarify docs.
1692
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001693- The wsgiref package has been added to the standard library.
1694
Nick Coghlan676725d2006-06-08 13:54:49 +00001695- The functions update_wrapper() and wraps() have been added to the functools
1696 module. These make it easier to copy relevant metadata from the original
1697 function when writing wrapper functions.
1698
Tim Petersd6a9eef2006-06-05 01:48:21 +00001699- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1700 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001701
Martin v. Löwis3f767792006-06-04 19:36:28 +00001702- Patch #1359618: Speed up charmap encoder by using a trie structure
1703 for lookup.
1704
Tim Petersd609b1a2006-06-02 23:22:51 +00001705- The functions in the ``pprint`` module now sort dictionaries by key
1706 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1707 if and only if its display required more than one line, although that
1708 wasn't documented. The new behavior increases predictability; e.g.,
1709 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1710
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001711- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1712 (thanks for J. J. Lee).
1713
Georg Brandl2b330372006-05-28 20:23:12 +00001714- Patch #1496206: improve urllib2 handling of passwords with respect to
1715 default HTTP and HTTPS ports.
1716
George Yoshidaf3c65de2006-05-28 16:39:09 +00001717- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1718
Bob Ippolito7298f272006-05-23 18:43:47 +00001719- Patch #1281707: speed up gzip.readline.
1720
Georg Brandlb89316f2006-05-17 15:51:16 +00001721- Patch #1180296: Two new functions were added to the locale module:
1722 format_string() to get the effect of "format % items" but locale-aware,
1723 and currency() to format a monetary number with currency sign.
1724
Georg Brandle3a25832006-05-17 14:56:04 +00001725- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1726 and several features added, such as speed and geometry control.
1727
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001728- Patch #1488881: add support for external file objects in bz2 compressed
1729 tarfiles.
1730
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001731- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1732 stdout arguments, making it possible to redirect input and output
1733 for remote debugging.
1734
1735- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1736 a couple of issues, notably handling of long file names using the
1737 GNU LONGNAME extension.
1738
1739- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1740 new flag when ``name`` is already the name of an option flag.
1741
1742- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1743 package.
1744
1745- Patch #1472854: make the rlcompleter.Completer class usable on non-
1746 UNIX platforms.
1747
1748- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1749
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001750- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001781What's New in Python 2.5 alpha 2?
1782=================================
1783
1784*Release date: 27-APR-2006*
1785
1786Core and builtins
1787-----------------
1788
Thomas Heller1b046642006-04-18 18:51:06 +00001789- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1790 by converting these apis from macros into exported functions again:
1791
1792 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1793 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1794 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1795 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1796 PyRun_String Py_CompileString
1797
Martin v. Löwis45294a92006-04-18 06:24:08 +00001798- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1799
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001800- All uses of PyStructSequence_InitType have been changed to initialize
1801 the type objects only once, even if the interpreter is initialized
1802 multiple times.
1803
Neal Norwitz61546162006-04-14 05:20:28 +00001804- Bug #1454485, array.array('u') could crash the interpreter. This was
1805 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1806 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1807
1808- Py_UNICODE is unsigned. It was always documented as unsigned, but
1809 due to a bug had a signed value in previous versions.
1810
Tim Peters3a5e8b12006-04-11 01:44:07 +00001811- Patch #837242: ``id()`` of any Python object always gives a positive
1812 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1813 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001814 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001815 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001816
Tim Peters3a5e8b12006-04-11 01:44:07 +00001817 def __hash__(self):
1818 return id(self) # WRONG
1819
1820 because a hash result must be a (short) Python int but it was always
1821 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001822 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001823 was always usable as a hash value before this patch. That's no longer
1824 necessarily so.
1825
1826- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001827 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001828 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001829 #1454844)
1830
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001831- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1832 involving generators that have paused outside of any ``try`` or ``with``
1833 blocks. (In 2.5a1, a paused generator that was part of a reference
1834 cycle could not be garbage collected, regardless of whether it was
1835 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001836
Anthony Baxter51bcb682006-04-05 14:51:42 +00001837Extension Modules

1839
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001840- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1841 is a macro.
1842
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001843- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1844 fails with an error condition.
1845
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001846- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1847
1848- Bug #1117761: bsddb.*open() no longer raises an exception when using
1849 the cachesize parameter.
1850
1851- Bug #1149413: bsddb.*open() no longer raises an exception when using
1852 a temporary db (file=None) with the 'n' flag to truncate on open.
1853
1854- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1855 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001856
Armin Rigoa9017c32006-04-19 11:50:27 +00001857- Patch #1062014: AF_UNIX sockets under Linux have a special
1858 abstract namespace that is now fully supported.
1859
Anthony Baxter51bcb682006-04-05 14:51:42 +00001860Library
1861-------
1862
Peter Astrand7d1d4362006-07-14 14:04:45 +00001863- Bug #1223937: subprocess.CalledProcessError reports the exit status
1864 of the process using the returncode attribute, instead of
1865 abusing errno.
1866
Tim Peters711bf302006-04-25 03:31:36 +00001867- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1868 a doctest to be skipped (the code is not run, and the expected output
1869 or exception is ignored).
1870
Nick Coghlanda2268f2006-04-24 04:37:15 +00001871- Fixed contextlib.nested to cope with exceptions being raised and
1872 caught inside exit handlers.
1873
Greg Wardab05edc2006-04-23 03:47:58 +00001874- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1875 hex, octal, or binary; add ``append_const`` action; keep going if
1876 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1877 added ``epilog`` for better help generation).
1878
Tim Peters21fbd572006-04-21 21:18:10 +00001879- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1880 called from a thread spawned as a side effect of importing a module.
1881
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001882- The pydoc module now supports documenting packages contained in
1883 .zip or .egg files.
1884
1885- The pkgutil module now has several new utility functions, such
1886 as ``walk_packages()`` to support working with packages that are either
1887 in the filesystem or zip files.
1888
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001889- The mailbox module can now modify and delete messages from
1890 mailboxes, in addition to simply reading them. Thanks to Gregory
1891 K. Johnson for writing the code, and to the 2005 Google Summer of
1892 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001893
Tim Petersc7605f22006-04-17 21:12:33 +00001894- The ``__del__`` method of class ``local`` in module ``_threading_local``
1895 returned before accomplishing any of its intended cleanup.
1896
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001897- Patch #790710: Add breakpoint command lists in pdb.
1898
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001899- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1900
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001901- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1902
Anthony Baxtere29002c2006-04-12 12:07:31 +00001903- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1904 Windows. Bug #1469163.
1905
Phillip J. Eby47032112006-04-11 01:07:43 +00001906- The warnings, linecache, inspect, traceback, site, and doctest modules
1907 were updated to work correctly with modules imported from zipfiles or
1908 via other PEP 302 __loader__ objects.
1909
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001910- Patch #1467770: Reduce usage of subprocess._active to processes which
1911 the application hasn't waited on.
1912
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001913- Patch #1462222: Fix Tix.Grid.
1914
Neal Norwitza31bf182006-04-09 03:35:43 +00001915- Fix exception when doing glob.glob('anything*/')
1916
Skip Montanaro262fb922006-04-21 02:31:07 +00001917- The pstats.Stats class accepts an optional stream keyword argument to
1918 direct output to an alternate file-like object.
1919
Anthony Baxter51bcb682006-04-05 14:51:42 +00001920Build
1921-----
1922
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001923- The Makefile now has a reindent target, which runs reindent.py on
1924 the library.
1925
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001926- Patch #1470875: Building Python with MS Free Compiler
1927
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001928- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001929
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001930- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1931 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001932 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001933 CXX from --with-cxx-main, see description in README.
1934
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001935- Patch #1429775: Link extension modules with the shared libpython.
1936
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001937- Fixed a libffi build problem on MIPS systems.
1938
Tim Peters8931ff12006-05-13 23:28:20 +00001939- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1940 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1941 and "%zu" for unsigned integers of type ``size_t``.
1942
Anthony Baxter51bcb682006-04-05 14:51:42 +00001943Tests
1944-----
1945
Nick Coghlanda2268f2006-04-24 04:37:15 +00001946- test_contextlib now checks contextlib.nested can cope with exceptions
1947 being raised and caught inside exit handlers.
1948
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001949- test_cmd_line now checks operation of the -m and -c command switches
1950
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001951- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1952 it separately and by hand. It also wasn't cleaning up its changes to
1953 the current Decimal context.
1954
Thomas Woutersabd08882006-04-26 15:53:30 +00001955- regrtest.py now has a -M option to run tests that test the new limits of
1956 containers, on 64-bit architectures. Running these tests is only sensible
1957 on 64-bit machines with more than two gigabytes of memory. The argument
1958 passed is the maximum amount of memory for the tests to use.
1959
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001960Tools
1961-----
1962
1963- Added the Python benchmark suite pybench to the Tools/ directory;
1964 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001966Documentation
1967-------------
1968
Tim Petersb06d28c2006-05-12 01:57:59 +00001969- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1970
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001971- PEP 343: Added Context Types section to the library reference
1972 and attempted to bring other PEP 343 related documentation into
1973 line with the implementation and/or python-dev discussions.
1974
Tim Peters8dc73d22006-04-24 02:03:16 +00001975- Bug #1337990: clarified that ``doctest`` does not support examples
1976 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001979What's New in Python 2.5 alpha 1?
1980=================================
1981
Anthony Baxterebed3f62006-04-03 15:03:44 +00001982*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001983
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001984Core and builtins
1985-----------------
1986
Nick Coghlan43832302006-04-23 17:04:07 +00001987- PEP 338: -m command line switch now delegates to runpy.run_module
1988 allowing it to support modules in packages and zipfiles
1989
Martin v. Löwisc661b882006-04-20 04:54:23 +00001990- On Windows, .DLL is not an accepted file name extension for
1991 extension modules anymore; extensions are only found if they
1992 end in .PYD.
1993
Martin v. Löwisea62d252006-04-03 10:56:49 +00001994- Bug #1421664: sys.stderr.encoding is now set to the same value as
1995 sys.stdout.encoding.
1996
Neal Norwitz92e212f2006-04-03 04:48:37 +00001997- __import__ accepts keyword arguments.
1998
Georg Brandlccadf842006-03-31 18:54:53 +00001999- Patch #1460496: round() now accepts keyword arguments.
2000
Anthony Baxter262c00a2006-03-30 10:53:17 +00002001- Fixed bug #1459029 - unicode reprs were double-escaped.
2002
Hye-Shik Changd478f342006-03-23 12:32:36 +00002003- Patch #1396919: The system scope threads are reenabled on FreeBSD
2004 5.4 and later versions.
2005
Neal Norwitze98ccf62006-03-23 05:39:47 +00002006- Bug #1115379: Compiling a Unicode string with an encoding declaration
2007 now gives a SyntaxError.
2008
Georg Brandlabd1ff82006-03-18 07:59:59 +00002009- Previously, Python code had no easy way to access the contents of a
2010 cell object. Now, a ``cell_contents`` attribute has been added
2011 (closes patch #1170323).
2012
Tim Peterscf79aac2006-03-16 01:14:46 +00002013- Patch #1123430: Python's small-object allocator now returns an arena to
2014 the system ``free()`` when all memory within an arena becomes unused
2015 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2016 freed. Some applications will see a drop in virtual memory size now,
2017 especially long-running applications that, from time to time, temporarily
2018 use a large number of small objects. Note that when Python returns an
2019 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002020 platform C library will in turn return that memory to the operating system.
2021 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002022 appears to be effective at least on Microsoft C and gcc-based systems.
2023 Thanks to Evan Jones for hard work and patience.
2024
Georg Brandl533ff6f2006-03-08 18:09:27 +00002025- Patch #1434038: property() now uses the getter's docstring if there is
2026 no "doc" argument given. This makes it possible to legitimately use
2027 property() as a decorator to produce a read-only property.
2028
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002029- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2030 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2031 of requiring an int or long in slicing and a few other contexts, enabling
2032 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2033
Neal Norwitz995acdf2006-03-07 05:01:00 +00002034- Fixed various bugs reported by Coverity's Prevent tool.
2035
Brett Cannonbf364092006-03-01 04:25:17 +00002036- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2037 new exception base class, BaseException, which has a new message attribute.
2038 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2039 Raising a string exception now raises a DeprecationWarning.
2040
Thomas Woutersfb609f42006-02-28 16:37:25 +00002041- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2042 explicitly relative, using 'from .module import name' to mean 'from the same
2043 package as this module is in. Imports without dots still default to the
2044 old relative-then-absolute, unless 'from __future__ import
2045 absolute_import' is used.
2046
Brett Cannona7446e32006-02-27 23:39:10 +00002047- Properly check if 'warnings' raises an exception (usually when a filter set
2048 to "error" is triggered) when raising a warning for raising string
2049 exceptions.
2050
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002051- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002052 The name was removed from Include/code.h.
2053
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002054- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002055
Guido van Rossum1968ad32006-02-25 22:38:04 +00002056- Patch 1433928:
2057 - The copy module now "copies" function objects (as atomic objects).
2058 - dict.__getitem__ now looks for a __missing__ hook before raising
2059 KeyError.
2060
Tim Peters84ef21c2006-02-28 20:39:06 +00002061- PEP 343: with statement implemented. Needs ``from __future__ import
2062 with_statement``. Use of 'with' as a variable will generate a warning.
2063 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002064 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002065 The following objects have __context__ methods:
2066 - The built-in file type.
2067 - The thread.LockType type.
2068 - The following types defined by the threading module:
2069 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2070 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002071
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002072- Fix the encodings package codec search function to only search
2073 inside its own package. Fixes problem reported in patch #1433198.
2074
2075 Note: Codec packages should implement and register their own
2076 codec search function. PEP 100 has the details.
2077
Tim Peters9ea89d22006-06-04 03:26:02 +00002078- PEP 353: Using ``Py_ssize_t`` as the index type.
2079
2080- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2081 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2082 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2083 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2084 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002085
Neal Norwitzfc76d632006-01-10 06:03:13 +00002086- Patch #1400181, fix unicode string formatting to not use the locale.
2087 This is how string objects work. u'%f' could use , instead of .
2088 for the decimal point. Now both strings and unicode always use periods.
2089
Neal Norwitz671b9e32006-01-09 07:07:12 +00002090- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2091 configure would break checking curses.h.
2092
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002093- Bug #959576: The pwd module is now builtin. This allows Python to be
2094 built on UNIX platforms without $HOME set.
2095
Neal Norwitzc10978f2005-12-19 06:07:16 +00002096- Bug #1072182, fix some potential problems if characters are signed.
2097
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002098- Bug #889500, fix line number on SyntaxWarning for global declarations.
2099
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002100- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2101
Neal Norwitze7214a12005-12-18 05:03:17 +00002102- Support for converting hex strings to floats no longer works.
2103 This was not portable. float('0x3') now raises a ValueError.
2104
Barry Warsaw2a38a862005-12-18 01:27:35 +00002105- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002106 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002107 is now displayed in interactive prompt banner.
2108
Georg Brandlfa166682005-12-17 21:45:17 +00002109- Implementation of PEP 341 - Unification of try/except and try/finally.
2110 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002111 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002112
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002113- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2114 now encodes backslash correctly.
2115
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002116- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2117
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002118- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002119 and long longs.
2120
Neal Norwitz67715f02005-11-09 06:59:35 +00002121- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002122 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002123 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002124
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002125- Replaced most Unicode charmap codecs with new ones using the
2126 new Unicode translate string feature in the builtin charmap
2127 codec; the codecs were created from the mapping tables available
2128 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2129 encodings now include a mapping for the Apple logo)
2130
Tim Peterse3547fd2005-12-16 23:13:57 +00002131- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002132
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002133- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002134
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002135- A new AST parser implementation was completed. The abstract
2136 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002137 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002138
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002139- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002140 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2141
Neal Norwitz708e51a2005-10-03 04:48:15 +00002142- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2143
Neal Norwitz11bd1192005-10-03 00:54:56 +00002144- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2145 Provide a warning when a directory is passed on the command line.
2146
Neal Norwitz40d37812005-10-02 01:48:49 +00002147- Fix segfault with invalid coding.
2148
2149- SF bug #772896: unknown encoding results in MemoryError.
2150
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002151- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002152 supported a __len__() method which evaluated to False when the iterator
2153 was empty.
2154
Guido van Rossum630db602005-09-20 18:49:54 +00002155- On 64-bit platforms, when __len__() returns a value that cannot be
2156 represented as a C int, raise OverflowError.
2157
Skip Montanarof8948ca2005-09-19 03:54:46 +00002158- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002159 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002160
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002161- SF bug #893549: parsing keyword arguments was broken with a few format
2162 codes.
2163
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002164- Changes donated by Elemental Security to make it work on AIX 5.3
2165 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2166 bug #105470: test_pwd fails on 64bit system (Opteron).
2167
Guido van Rossum539c6622005-09-14 17:49:54 +00002168- Changes donated by Elemental Security to make it work on HP-UX 11 on
2169 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2170
Georg Brandl4550b8d2005-08-26 06:43:52 +00002171- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002172 (fixes bug #1119418).
2173
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002174- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2175
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002176- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2177 exceptions that cause a function to exit.
2178
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002179- The implementation of set() and frozenset() was revised to use its
2180 own internal data structure. Memory consumption is reduced by 1/3
2181 and there are modest speed-ups as well. The API is unchanged.
2182
Tim Petersde7990b2005-07-17 23:45:23 +00002183- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2184
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002185- SF bug #1229429: PyObject_CallMethod failed to decrement some
2186 reference counts in some error exit cases.
2187
Tim Petersecc6e6a2005-07-10 22:30:55 +00002188- SF bug #1185883: Python's small-object memory allocator took over
2189 a block managed by the platform C library whenever a realloc specified
2190 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002191 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002192 portable way to copy data from the C-managed block into Python's
2193 small-object space without risking a memory fault. Python's small-object
2194 realloc now leaves such blocks under the control of the platform C
2195 realloc.
2196
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002197- SF bug #1232517: An overflow error was not detected properly when
2198 attempting to convert a large float to an int in os.utime().
2199
Raymond Hettinger3296e692005-06-29 23:29:56 +00002200- SF bug #1224347: hex longs now print with lowercase letters just
2201 like their int counterparts.
2202
Michael W. Hudson188d4362005-06-20 16:52:57 +00002203- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2204 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2205 interpreter states; back out that fix and do a better job (see
2206 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2207 for a longer write-up of the problem).
2208
Michael W. Hudsondf888462005-06-03 14:41:55 +00002209- SF patch #1180995: marshal now uses a binary format by default when
2210 serializing floats.
2211
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002212- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2213 the routines that promise to produce IEEE 754 binary representations
2214 of floats now simply copy bytes around.
2215
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002216- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2217 278.
2218
Brett Cannonc3647ac2005-04-26 03:45:26 +00002219- patch #1109424: int, long, float, complex, and unicode now check for the
2220 proper magic slot for type conversions when subclassed. Previously the
2221 magic slot was ignored during conversion. Semantics now match the way
2222 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002223 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002224 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002225 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002226
Barry Warsawc8d907c2005-04-19 23:43:40 +00002227- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2228 NULL, now raise an AttributeError when attempting to set or delete the
2229 attribute. Previously a TypeError was raised, but this was inconsistent
2230 with the equivalent pure-Python implementation.
2231
Michael W. Hudson774479c2005-04-18 08:46:17 +00002232- It is now safe to call PyGILState_Release() before
2233 PyEval_InitThreads() (note that if there is reason to believe there
2234 are multiple threads around you still must call PyEval_InitThreads()
2235 before using the Python API; this fix is for extension modules that
2236 have no way of knowing if Python is multi-threaded yet).
2237
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002238- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2239 disabled caused a crash.
2240
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002241- Bug #1165306: instancemethod_new allowed the creation of a method
2242 with im_class == im_self == NULL, which caused a crash when called.
2243
Tim Petersecc6e6a2005-07-10 22:30:55 +00002244- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002245 fixes the crash seen in bug #1165761
2246
Raymond Hettinger96229b12005-03-11 06:49:40 +00002247- Added two new builtins, any() and all().
2248
Brett Cannon409d8f22005-03-05 06:47:57 +00002249- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002250 (e.g., ``class C(): pass`` is no longer a syntax error).
2251 Patch #1176012 added support to the 'parser' module and 'compiler' package
2252 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002253
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002254- Patch #1115086: Support PY_LONGLONG in structmember.
2255
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002256- Bug #1155938: new style classes did not check that __init__() was
2257 returning None.
2258
Tim Petersecc6e6a2005-07-10 22:30:55 +00002259- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002260 ('\') with a specific error message.
2261
Martin v. Löwisff232d72005-03-03 09:24:38 +00002262- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2263
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002264- Bug #1124295: the __name__ attribute of file objects was
2265 inadvertently made inaccessible in restricted mode.
2266
Tim Petersecc6e6a2005-07-10 22:30:55 +00002267- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002268 an ferror() call.
2269
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002270- min() and max() now support key= arguments with the same meaning as in
2271 list.sort().
2272
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002273- The peephole optimizer now performs simple constant folding in expressions:
2274 (2+3) --> (5).
2275
Raymond Hettingera422c342005-01-11 03:03:27 +00002276- set and frozenset objects can now be marshalled. SF #1098985.
2277
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002278- Bug #1077106: Poor argument checking could cause memory corruption
2279 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002280
Jeremy Hyltonab630502005-02-04 18:44:06 +00002281- The parser did not complain about future statements in illegal
2282 positions. It once again reports a syntax error if a future
2283 statement occurs after anything other than a doc string.
2284
Neil Schemenauercf52c072005-08-12 17:34:58 +00002285- Change the %s format specifier for str objects so that it returns a
2286 unicode instance if the argument is not an instance of basestring and
2287 calling __str__ on the argument returns a unicode instance.
2288
Tim Petersf4e69282006-02-27 17:15:31 +00002289- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2290 current thread state when the auto-GIL-state machinery knows about
2291 it (since the thread state is being deleted, continuing to remember it
2292 can't help, but can hurt if another thread happens to get created with
2293 the same thread id).
2294
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002295Extension Modules
2296-----------------
2297
Georg Brandl43f08a82006-03-31 18:01:16 +00002298- Patch #1380952: fix SSL objects timing out on consecutive read()s
2299
Neal Norwitz05a45592006-03-20 06:30:08 +00002300- Patch #1309579: wait3 and wait4 were added to the posix module.
2301
Anthony Baxterfa869072006-03-20 05:21:58 +00002302- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2303 In addition, the existing ulaw code was updated.
2304
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002305- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002306 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002307
Neal Norwitz10be10c2006-03-16 06:50:13 +00002308- Everything under lib-old was removed. This includes the following modules:
2309 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002310 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002311 util, whatsound, whrandom, zmod
2312
2313- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2314
2315- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002316 is deprecated. The undocumented re.engine variable no longer exists.
2317
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002318- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2319 SS2 (single-shift 2) escape sequences correctly.
2320
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002321- The unicodedata module was updated to the 4.1 version of the Unicode
2322 database. The 3.2 version is still available as unicodedata.db_3_2_0
2323 for applications that require this specific version (such as IDNA).
2324
Neal Norwitzb62c4332006-03-04 18:35:47 +00002325- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002485- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2486 been renamed to have only a single underscore prefix. This was done to
2487 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002488
Nick Coghlan43832302006-04-23 17:04:07 +00002489- PEP 338: new module runpy defines a run_module function to support
2490 executing modules which provide access to source code or a code object
2491 via the PEP 302 import mechanisms.
2492
Anthony Baxter93f5b932006-04-03 08:05:07 +00002493- The email module's parsedate_tz function now sets the daylight savings

2501 in attribute values.
2502
Anthony Baxterc51ee692006-04-01 00:57:31 +00002503- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002504 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002505 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002506 module will not be built.
2507
Tim Petersc17976e2006-04-01 00:26:53 +00002508- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2509 aren't officially supported here, and trying to use them will probably
2510 raise an exception some day. But dicts have been allowed, and "mostly
2511 worked", so support for them won't go away without warning.
2512
Georg Brandl338ef7d2006-03-31 18:42:16 +00002513- Bug #1445068: getpass.getpass() can now be given an explicit stream
2514 argument to specify where to write the prompt.
2515

2531
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002532- email 4.0 package now integrated. This is largely the same as the email 3.0
2533 package that was included in Python 2.3, except that PEP 8 module names are
2534 now used (e.g. mail.message instead of email.Message). The MIME classes
2535 have been moved to a subpackage (e.g. email.mime.text instead of
2536 email.MIMEText). The old names are still supported for now. Several
2537 deprecated Message methods have been removed and lots of bugs have been
2538 fixed. More details can be found in the email package documentation.
2539
Walter Dörwald40108c92006-03-27 08:15:44 +00002540- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2541 (a subclass of tuple) that provides incremental decoders and encoders
2542 (a way to use stateful codecs without the stream API). Python functions
2543 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2544 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2545 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002547- Patch #1359365: Calling next() on a closed StringIO.String object raises
2548 a ValueError instead of a StopIteration now (like file and cString.String do).
2549 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2550 called before (like file and StringIO.StringIO do).

Tim Petersda1329b2006-02-27 16:50:01 +00002599- Patch #1349118: urllib now supports user:pass@ style proxy
Martin v. Löwis3e865952006-01-24 15:51:21 +00002600 specifications, raises IOErrors when proxies for unsupported protocols
2601 are defined, and uses the https proxy on https redirections.

2618
Neal Norwitz338e7862005-12-23 21:27:46 +00002619- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2620 LoadError as documented, instead of IOError. For compatibility,
2621 LoadError subclasses IOError.
2622
Brett Cannon3cbd0382005-12-16 22:49:23 +00002623- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002624 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2625 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2626 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2627 Ronald L. Rivest offered this advice for Python:
2628
2629 "The consensus of researchers in this area (at least as
2630 expressed at the NIST Hash Function Workshop 10/31/05),
2631 is that SHA-256 is a good choice for the time being, but
2632 that research should continue, and other alternatives may
2633 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002634
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002635- Added a subset of Fredrik Lundh's ElementTree package. Available

2688 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002689 correct line numbers for decoding errors in source code.

2712 to W3C name (404 -> 'Not Found'). RFE #1216944.
2713
Georg Brandl9e43acf2005-07-04 17:16:07 +00002714- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2715 as this can cause problems with apps closing all file descriptors.

2728 Bug #1224621.
2729
Raymond Hettinger68c04532005-06-10 11:05:19 +00002730- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002731 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002732 the generate_tokens() function now accepts a callable argument that
2733 terminates by raising StopIteration.
2734
Georg Brandl9166e1a2005-06-04 09:20:03 +00002735- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2750
Raymond Hettinger267b8682005-03-27 10:47:39 +00002751- decimal operator and comparison methods now return NotImplemented
2752 instead of raising a TypeError when interacting with other types. This
2753 allows other classes to implement __radd__ style methods and have them
2754 work as expected.
2755
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002756- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00002794- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2795 disables recursive traversal through instance attributes, which can
2796 be exploited in various ways.
2797
Tim Peterse3547fd2005-12-16 23:13:57 +00002798- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002799 flags on the HTTP listening socket.
2800

2810
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002811- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2812
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002813- Enhancements to the csv module:
2814
2815 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002816 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002817 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002818 + Dialect parameter parsing has been re-implemented to improve error
2819 reporting.
2820 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2821 dictates.
2822 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002823 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002824 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002825 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2826 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002827 + reader now allows \r characters to be quoted (previously it only allowed
2828 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002829 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002830 + Dialect classes passed to the module are no longer instantiated by
2831 the module before being parsed (the former validation scheme required
2832 this, but the mechanism was unreliable).
2833 + The dialect registry now contains instances of the internal
2834 C-coded dialect type, rather than references to python objects.
2835 + the internal c-coded dialect type is now immutable.
2836 + register_dialect now accepts the same keyword dialect specifications
2837 as the reader and writer, allowing the user to register dialects
2838 without first creating a dialect class.
2839 + a configurable limit to the size of parsed fields has been added -
2840 previously, an unmatched quote character could result in the entire
2841 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002842 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002843 the parser field size limit (returning the former limit). The initial
2844 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002845 + A line_num attribute has been added to the reader object, which tracks
2846 the number of lines read from the source iterator. This is not
2847 the same as the number of records returned, as records can span
2848 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002849 + reader and writer objects were not being registered with the cyclic-GC.
2850 This has been fixed.
2851
Brett Cannone6539c42005-01-08 02:43:53 +00002852- _DummyThread objects in the threading module now delete self.__block that is
2853 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2854 lock primitives tend to be limited in number and thus should not be wasted on
2855 a _DummyThread object. Fixes bug #1089632.
2856
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002857- The imghdr module now detects Exif files.
2858
Raymond Hettinger6065d322004-12-20 23:51:53 +00002859- StringIO.truncate() now correctly adjusts the size attribute.
2860 (Bug #951915).
2861
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002862- locale.py now uses an updated locale alias table (built using
2863 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2864 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002865 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002866
Raymond Hettinger3557f422004-12-07 12:02:02 +00002867- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2868
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002869- the pickle module no longer accepts the deprecated None option in the
2870 args tuple returned by __reduce__().
2871
Brett Cannon84667c02004-12-07 03:25:18 +00002872- optparse now optionally imports gettext. This allows its use in setup.py.
2873
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002874- the pickle module no longer uses the deprecated bin parameter.
2875
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002876- the shelve module no longer uses the deprecated binary parameter.
2877
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002878- the pstats module no longer uses the deprecated ignore() method.
2879
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002880- the filecmp module no longer uses the deprecated use_statcache argument.
2881
Raymond Hettinger664347b2004-12-04 21:21:53 +00002882- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2883 extended or overridden by subclasses. Formerly, the subclassed method would
2884 be ignored by the rest of the module. (Bug #1078905).
2885
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002886- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002887 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002888
Walter Dörwald36733692004-12-22 12:50:50 +00002889- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2890 once when a size argument is given. This prevents a buffer overflow in the
2891 tokenizer with very long source lines.
2892
Barry Warsaw538561e2006-01-01 21:48:54 +00002893- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2894 immediately after creating the object, without any intervening
2895 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002896
Skip Montanaro05885812005-01-16 20:48:27 +00002897- The reconvert.quote function can now emit triple-quoted strings. The
2898 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002899
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002900- ``UserString.MutableString`` now supports negative indices in
2901 ``__setitem__`` and ``__delitem__``
2902
Greg Ward40407942005-03-05 02:53:17 +00002903- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2904 correctly.
2905
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002906- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2907 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2908 character even if the user has passed a size parameter to get a proper
2909 line ending. Remove the special handling of a "\r\n" that has been split
2910 between two lines.
2911
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002912- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2913 about illegal code points. The codec now supports PEP 293 style error
2914 handlers.
2915
Walter Dörwald78a78b02005-09-01 12:04:29 +00002916- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002917 from the input stream, so that the output is a byte string in the correct
2918 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002919
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002920- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2921 considering it exactly like a '*'.
2922
Walter Dörwald007f8df2005-10-09 19:42:27 +00002923- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2924 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002925
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002926- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2927
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002928- Patch #1413711: Certain patterns of differences were making difflib
2929 touch the recursion limit.
2930
Walter Dörwald58917a62006-03-31 15:26:22 +00002931- Bug #947906: An object oriented interface has been added to the calendar
2932 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002933 called as a script (e.g. via ``python -mcalendar``). Localized month and
2934 weekday names can be ouput (even if an exotic encoding is used) using
2935 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002936
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002937Build
2938-----
2939
Neal Norwitz602d3392006-03-31 08:21:40 +00002940- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2941 by using -mieee gcc option.
2942
Martin v. Löwis86d66262006-02-17 08:40:11 +00002943- Patch #1432345: Make python compile on DragonFly.
2944
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002945- Build support for Win64-AMD64 was added.
2946
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002947- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2948
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002949- Patch #881820: look for openpty and forkpty also in libbsd.
2950
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002951- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2952 The zlib module is now builtin on Windows.
2953
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002954- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2955
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002956- Bug #1189330: configure did not correctly determine the necessary
2957 value of LINKCC if python was built with GCC 4.0.
2958
Trent Mick8321b422005-07-26 02:29:21 +00002959- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2960 vulnerability in zlib 1.2.1 and 1.2.2.
2961
Brett Cannon08cd5982005-04-24 22:26:38 +00002962- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2963 flags that change binary compatibility. Changes were also made to
2964 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002965 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002966
Bob Ippolitoed233462005-03-29 13:47:59 +00002967- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2968 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2969 no longer exists). This configure patch makes things right.
2970
Martin v. Löwise2713be2005-03-08 15:03:08 +00002971- Bug #1158607: Build with --disable-unicode again.
2972
Brett Cannon46d96232005-02-16 00:07:19 +00002973- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2974 defined. Discovered as a result of not being able to build on OS X.
2975
Brett Cannon516592f2004-12-07 00:42:59 +00002976- setup.py now uses the directories specified in LDFLAGS using the -L option
2977 and in CPPFLAGS using the -I option for adding library and include
2978 directories, respectively, for compiling extension modules against. This has
2979 led to the core being compiled using the values in CPPFLAGS. It also removes
2980 the need for the special-casing of both DarwinPorts and Fink for darwin since
2981 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2982 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2983 Fink, ``-I/opt/local/include`` for DarwinPorts).
2984
Brett Cannon43802422005-02-10 20:48:03 +00002985- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2986 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2987 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2988 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002990C API
2991-----
2992
Tim Petersc9d78aa2006-03-26 23:27:58 +00002993- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2994 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2995 is obtained via the ``PyObject_`` family, it must be released via the
2996 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2997 always been officially true, but when Python's small-object allocator was
2998 introduced, an attempt was made to cater to a few extension modules
2999 discovered at the time that obtained memory via ``PyObject_New`` but
3000 released it via ``PyMem_DEL``. It's years later, and if such code still
3001 exists it will fail now (probably with segfaults, but calling wrong
3002 low-level memory management functions can yield many symptoms).
3003
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003004- Added a C API for set and frozenset objects.
3005
Raymond Hettinger66517482004-12-03 11:45:13 +00003006- Removed PyRange_New().
3007
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003008- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3009 mapping argument now. This string is used as a mapping table. Byte values
3010 greater than the length of the string and 0xFFFE are treated as undefined
3011 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003018
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003019- Patch #1276356: New resource "urlfetch" is implemented. This enables
3020 even impatient people to run tests that require remote files.
