Guido van Rossumc69ac252006-08-10 18:09:25 +0000896What's New in Python 2.5 release candidate 1?

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000898
Anthony Baxterb4096662006-08-16 03:42:26 +0000899*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000900
901Core and builtins
902-----------------
903
Neal Norwitz24b6f202006-09-05 04:43:56 +0000904- Fix infinite recursion when subclassing long and overriding __hash__.
905
906- Fix concatenation (+=) of long strings.
907
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000908- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000909 compared equal or unequal to a string and a UnicodeDecodeError
910 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000911
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000912 Instead, the equal (==) and unequal (!=) comparison operators will
913 now issue a UnicodeWarning and interpret the two objects as
914 unequal. The UnicodeWarning can be filtered as desired using
915 the warning framework, e.g. silenced completely, turned into an
916 exception, logged, etc.
917
918 Note that compare operators other than equal and unequal will still
919 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000920
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000921- Fix segfault when doing string formatting on subclasses of long.
922
923- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
924 with new-style classes.
925
926- Fix bug related to __len__ functions returning negative values with
927 classic classes.
928
929- Patch #1538606, Fix __index__() clipping. There were some problems
930 discovered with the API and how integers that didn't fit into Py_ssize_t
931 were handled. This patch attempts to provide enough alternatives
932 to effectively use __index__.
933
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000934- Bug #1536021: __hash__ may now return long int; the final hash
935 value is obtained by invoking hash on the long int.
936
Thomas Hellerab1049c2006-08-08 17:37:00 +0000937- Bug #1536786: buffer comparison could emit a RuntimeWarning.
938
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000939- Bug #1535165: fixed a segfault in input() and raw_input() when
940 sys.stdin is closed.
941
Thomas Heller74d36f02006-08-04 18:17:40 +0000942- On Windows, the PyErr_Warn function is now exported from
943 the Python dll again.
944
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000945- Bug #1191458: tracing over for loops now produces a line event
946 on each iteration. Fixing this problem required changing the .pyc
947 magic number. This means that .pyc files generated before 2.5c1
948 will be regenerated.
949
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000950- Bug #1333982: string/number constants were inappropriately stored
951 in the byte code and co_consts even if they were not used, ie
952 immediately popped off the stack.
953
Georg Brandle9462c72006-08-04 18:03:37 +0000954- Fixed a reference-counting problem in property().
955
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000956
957Library
958-------
959
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000960- Fix a bug in the ``compiler`` package that caused invalid code to be
961 generated for generator expressions.
962
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000963- The distutils version has been changed to 2.5.0. The change to
964 keep it programmatically in sync with the Python version running
965 the code (introduced in 2.5b3) has been reverted. It will continue
966 to be maintained manually as static string literal.
967
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000968- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000969 and this cannot be converted to the required C type, an exception is
970 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000971 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000972
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000973- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000974 an exception.
975
Tim Peterscbdd3502006-09-05 01:47:53 +0000976- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000977 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000978 workarounds for clocks with low resolution, to stop the code yielding
979 duplicate UUIDs.
980
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000981- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
982 before raising SystemExit, allowing IDLE to honor quit() and exit().
983
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000984- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
985
Georg Brandl7a1af772006-08-14 21:55:28 +0000986- Patch #1536071: trace.py should now find the full module name of a
987 file correctly even on Windows.
988
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000989- logging's atexit hook now runs even if the rest of the module has
990 already been cleaned up.
991
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000992- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000993
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000994- Bug #1531405, format_exception no longer raises an exception if
995 str(exception) raised an exception.
996
Neil Schemenauer06ded092006-08-04 16:20:30 +0000997- Fix a bug in the ``compiler`` package that caused invalid code to be
998 generated for nested functions.

1009 raises the correct exceptions.
1010
Thomas Heller1ce433e2006-08-14 16:20:04 +00001011- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1012 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1013
Thomas Heller86720042006-08-14 11:17:48 +00001014- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1015 uses the _as_parameter_ attribute when objects are passed to foreign
1016 function calls. The ctypes version number was changed to 1.0.1.
1017
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001018- Bug #1530559, struct.pack raises TypeError where it used to convert.
1019 Passing float arguments to struct.pack when integers are expected
1020 now triggers a DeprecationWarning.
1021
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001022

1044-----
1045
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001046- Bug #1535502, build _hashlib on Windows, and use masm assembler
1047 code in OpenSSL.
1048
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001049- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001051- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001052
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001053
Tim Peters4643c2f2006-08-10 22:45:34 +00001054C API
1055-----
1056
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001057- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1058
Tim Peters4643c2f2006-08-10 22:45:34 +00001059- Bug #1069160. Internal correctness changes were made to
1060 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1061 the documentation was changed to state that the return value
1062 is always 1 (normal) or 0 (if the specified thread wasn't found).

Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001068*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001069
1070Core and builtins
1071-----------------
1072
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001073- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001074 returned a long (see PEP 353).
1075
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001076- Bug #1515471: string.replace() accepts character buffers again.
1077
Neal Norwitz07aadb12006-07-30 06:55:48 +00001078- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1079 This provides the proper warning for struct.pack().
1080 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1081
Neal Norwitz0d62a062006-07-30 06:53:31 +00001082- Patch #1531113: Fix augmented assignment with yield expressions.
1083 Also fix a SystemError when trying to assign to yield expressions.
1084
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001085- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1086 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1087 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1088 excessive filesystem operations during imports.
1089
Tim Petersbc24eee2006-07-27 01:14:53 +00001090- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1091 operations on signed longs that are formally undefined by C.
1092 Unfortunately, at least one compiler now cares about that, so complicated
1093 the code to make that compiler happy again.
1094
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001095- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1096
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001097- Patch #1232023: Stop including current directory in search
1098 path on Windows.
1099
Neal Norwitze1fdb322006-07-21 05:32:28 +00001100- Fix some potential crashes found with failmalloc.
1101
Neal Norwitze7563102006-07-17 01:00:16 +00001102- Fix warnings reported by Klocwork's static analysis tool.
1103
Neal Norwitz84be93b2006-07-16 01:50:38 +00001104- Bug #1512814, Fix incorrect lineno's when code within a function
1105 had more than 255 blank lines.
1106
Georg Brandl9dceedb2006-07-12 15:31:17 +00001107- Patch #1521179: Python now accepts the standard options ``--help`` and
1108 ``--version`` as well as ``/?`` on Windows.
1109
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001110- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001111 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001112 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001113
Tim Peters112aad32006-07-19 00:03:19 +00001114- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001115 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001116 new ``sys._current_frames()`` returns a dictionary with one entry,
1117 mapping the faux "thread id" 0 to the current frame.
1118
Ronald Oussoren3075e162006-07-25 20:28:55 +00001119- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001120
Ronald Oussoren3075e162006-07-25 20:28:55 +00001121
Neal Norwitza1f10902006-07-12 07:28:29 +00001122Library
1123-------
1124
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001125- Correction of patch #1455898: In the mbcs decoder, set final=False
1126 for stream decoder, but final=True for the decode function.
1127
Georg Brandl07fec3a2006-08-01 18:49:24 +00001128- os.urandom no longer masks unrelated exceptions like SystemExit or
1129 KeyboardInterrupt.
1130
Tim Peters4643c2f2006-08-10 22:45:34 +00001131- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001132 shutil.copytree on Windows
1133
Georg Brandle34ac7c2006-07-30 11:07:23 +00001134- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1135 refers to file descriptors, not file objects.
1136
Tim Peterscbdd3502006-09-05 01:47:53 +00001137- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001138 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001139 #1513611, and probably others.
1140
Georg Brandledd9b0d2006-07-29 09:33:26 +00001141- Bug #1441397: The compiler module now recognizes module and function
1142 docstrings correctly as it did in Python 2.4.
1143
Tim Peters6f681472006-07-27 23:44:37 +00001144- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1145 lost that tests are sorted by name before being run. This rarely
1146 matters for well-written tests, but can create baffling symptoms if
1147 side effects from one test to the next affect outcomes. ``DocTestFinder``
1148 has been changed to sort the list of tests it returns.
1149
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001150- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001151 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001152
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001153- Bug #978833: Really close underlying socket in _socketobject.close.
1154
Georg Brandldb232dc2006-08-20 13:15:43 +00001155- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1156 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001157
Georg Brandlcf0c1722006-07-26 07:23:32 +00001158- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1159 to recursive calls and call it with the failing package name.
1160
Martin v. Löwis0b483032006-07-25 09:53:12 +00001161- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1162
Georg Brandlc13c34c2006-07-24 14:09:56 +00001163- Patch #1515343: Fix printing of deprecated string exceptions with a
1164 value in the traceback module.
1165
Greg Ward48fae7a2006-07-23 16:05:51 +00001166- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1167
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001168- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1169
Brett Cannoncaebe222006-07-18 04:41:36 +00001170- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1171 argument tuple. For arguments where zero is illegal, the value is forced to
1172 the minimum value that is correct. This is to support an undocumented but
1173 common way people used to fill in inconsequential information in the time
1174 tuple pre-2.4.
1175
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001176- Patch #1220874: Update the binhex module for Mach-O.
1177
Barry Warsawb110bad2006-07-21 14:51:07 +00001178- The email package has improved RFC 2231 support, specifically for
1179 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1180 (name*0=<blah>) parameter continuations. This may change the types of
1181 values returned from email.message.Message.get_param() and friends.
1182 Specifically in some cases where non-encoded continuations were used,
1183 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1184 will just return the string (since non-encoded continuations don't have
1185 charset and language parts).
1186
1187 Also, whereas % values were decoded in all parameter continuations, they are
1188 now only decoded in encoded parameter parts.
1189
Ronald Oussoren3075e162006-07-25 20:28:55 +00001190- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1191
1192- Bug #1517996: IDLE now longer shows the default Tk menu when a
1193 path browser, class browser or debugger is the frontmost window on MacOS X
1194
Barry Warsaw00decd72006-07-27 23:43:15 +00001195- Patch #1520294: Support for getset and member descriptors in types.py,
1196 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1197 of an object against these built-in types and more importantly, for getting
1198 their docstrings printed in the interactive interpreter's help() function.

1202-----------------
1203
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001204- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1205 a socket operation on a socket with a timeout, the exception will be
1206 caught correctly. Previously, the exception was not caught.
1207
Thomas Heller1393d6a2006-07-28 21:43:20 +00001208- Patch #1529514: The _ctypes extension is now compiled on more
1209 openbsd target platforms.
1210
Tim Peters9cab5932006-07-28 00:30:00 +00001211- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1212 a memory leak, affecting pickles and deep copies.
1213
Tim Petersbc24eee2006-07-27 01:14:53 +00001214- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1218
Thomas Hellerce049a02006-07-14 17:51:14 +00001219- Patch #1521817: Index range checking on ctypes arrays containing
1220 exactly one element enabled again. This allows iterating over these
1221 arrays, without the need to check the array size before.
1222
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001223- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001224 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001225 /dev/null in certain cases; this is now fixed.
1226
Thomas Heller47d7a062006-07-12 08:43:47 +00001227- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1228 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001229
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001230- Because of a misspelled preprocessor symbol, ctypes was always
1231 compiled without thread support; this is now fixed.
1232
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001233- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1234 methods now allow their database parameter to be None as the
1235 sleepycat API allows.
1236
Matt Flemingec926502006-07-28 11:27:27 +00001237- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1238 bluetooth API compared with Linux and FreeBSD.
1239
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001240Tests
1241-----
1242
1243- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1244 how long the test file should take to play. Now accepts taking 2.93 secs
1245 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1246
Georg Brandl4793aa32006-07-28 18:31:39 +00001247- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1248 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1249 run via ``regrtest.py``. Now they do.

Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001251Build
1252-----
1253
1254- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1255
Ronald Oussoren26cad082006-08-01 21:00:57 +00001256Mac
1257---
1258
1259- PythonLauncher now works correctly when the path to the script contains
1260 characters that are treated specially by the shell (such as quotes).
1261
1262- Bug #1527397: PythonLauncher now launches scripts with the working directory
1263 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001264 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001265 expect.

1274-----------------
1275
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001276- Bug #1441486: The literal representation of -(sys.maxint - 1)
1277 again evaluates to a int object, not a long.
1278
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001279- Bug #1501934: The scope of global variables that are locally assigned
1280 using augmented assignment is now correctly determined.
1281
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001282- Bug #927248: Recursive method-wrapper objects can now safely
1283 be released.
1284
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001285- Bug #1417699: Reject locale-specific decimal point in float()
1286 and atof().
1287
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001288- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1289 omit a default "error" argument for NULL pointer. This allows
1290 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001291
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001292- Bug #1519018: 'as' is now validated properly in import statements.
1293
Neal Norwitz28746ab2006-07-09 22:14:42 +00001294- On 64 bit systems, int literals that use less than 64 bits are
1295 now ints rather than longs.
1296
Neal Norwitzed657552006-07-10 00:04:44 +00001297- Bug #1512814, Fix incorrect lineno's when code at module scope
1298 started after line 256.
1299
Tim Peters32a83612006-07-10 21:08:24 +00001300- New function ``sys._current_frames()`` returns a dict mapping thread
1301 id to topmost thread stack frame. This is for expert use, and is
1302 especially useful for debugging application deadlocks. The functionality
1303 was previously available in Fazal Majid's ``threadframe`` extension
1304 module, but it wasn't possible to do this in a wholly threadsafe way from
1305 an extension.

1314
Tim Peters32a83612006-07-10 21:08:24 +00001315- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001316 environment variable to be set in order to the SDK environment
1317 for finding the compiler, include files, etc.

1322
Thomas Woutersadd19112006-07-05 11:03:49 +00001323- string.Template() now correctly handles tuple-values. Previously,
1324 multi-value tuples would raise an exception and single-value tuples would
1325 be treated as the value they contain, instead.
1326
Martin v. Löwisede77f52006-07-03 13:01:35 +00001327- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1328 even if some data are received.
1329
Martin v. Löwis45482392006-07-03 12:28:58 +00001330- Bug #1267547: Put proper recursive setup.py call into the
1331 spec file generated by bdist_rpm.

Martin v. Löwis2b88f632006-07-03 10:19:49 +00001333- Bug #1514693: Update turtle's heading when switching between
1334 degrees and radians.
1335
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001336- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001337 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001338
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001339- Bug #1514703: Only setup canvas window in turtle when the canvas
1340 is created.
1341
Martin v. Löwis7596e832006-07-01 15:33:37 +00001342- Bug #1513223: .close() of a _socketobj now releases the underlying
1343 socket again, which then gets closed as it becomes unreferenced.
1344
Fred Drake10497c82006-06-29 02:57:48 +00001345- Bug #1504333: Make sgmllib support angle brackets in quoted
1346 attribute values.
1347
1348- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1349 sgmllib ('[' and ']' were not accepted).
1350
Georg Brandl1be63af2006-06-28 20:23:25 +00001351- Fix a bug in the turtle module's end_fill function.
1352
Brett Cannon53ab5b72006-06-22 16:49:14 +00001353- Bug #1510580: The 'warnings' module improperly required that a Warning
1354 category be either a types.ClassType and a subclass of Warning. The proper
1355 check is just that it is a subclass with Warning as the documentation states.
1356
Georg Brandlad29e632006-06-21 17:45:17 +00001357- The compiler module now correctly compiles the new try-except-finally
1358 statement (bug #1509132).
1359
Neal Norwitz60373cd2006-06-22 06:30:50 +00001360- The wsgiref package is now installed properly on Unix.
1361
Vinay Sajip28e57612006-07-01 10:45:20 +00001362- A bug was fixed in logging.config.fileConfig() which caused a crash on
1363 shutdown when fileConfig() was called multiple times.
1364
Gerhard Häring762fbd32006-07-02 17:48:30 +00001365- The sqlite3 module did cut off data from the SQLite database at the first
1366 null character before sending it to a custom converter. This has been fixed
1367 now.
1368
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001369Extension Modules
1370-----------------
1371
Tim Peters112aad32006-07-19 00:03:19 +00001372- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1373 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1374 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001375
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001376- Assigning None to pointer type fields in ctypes structures possible
1377 overwrote the wrong fields, this is fixed now.
1378
1379- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1380 on non-Windows platforms.
1381
1382- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1383 integer or long, without range checking.
1384
1385- Patch #1517790: It is now possible to use custom objects in the ctypes
1386 foreign function argtypes sequence as long as they provide a from_param
1387 method, no longer is it required that the object is a ctypes type.
1388
1389- The '_ctypes' extension module now works when Python is configured
1390 with the --without-threads option.
1391
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001392- Bug #1513646: os.access on Windows now correctly determines write
1393 access, again.
1394
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001395- Bug #1512695: cPickle.loads could crash if it was interrupted with

1407
Tim Peters32a83612006-07-10 21:08:24 +00001408- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001409 Previously, the slight difference could cause compilation errors of the
1410 'zlib' module on systems with more than one version of zlib.
1411
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001412- The MSI compileall step was fixed to also support a TARGETDIR
1413 with spaces in it.

Nick Coghlan2d792252006-07-06 13:47:18 +00001430- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1431 documentation for the warnings module.
1432
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001433- Patch #1509163: MS Toolkit Compiler no longer available.

1444-----------------
1445
Georg Brandla56b9152006-06-19 06:35:54 +00001446- Patch #1507676: Error messages returned by invalid abstract object operations
1447 (such as iterating over an integer) have been improved and now include the
1448 type of the offending object to help with debugging.
1449
Brett Cannonea3912b2006-06-13 21:46:41 +00001450- Bug #992017: A classic class that defined a __coerce__() method that returned
1451 its arguments swapped would infinitely recurse and segfault the interpreter.
1452
Neal Norwitz909eb122006-06-12 02:13:21 +00001453- Fix the socket tests so they can be run concurrently.
1454
Neal Norwitzb9845e72006-06-12 02:11:18 +00001455- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001456 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001457
Brett Cannon22565aa2006-06-09 22:31:23 +00001458- Bug #532646: object.__call__() will continue looking for the __call__
1459 attribute on objects until one without one is found. This leads to recursion
1460 when you take a class and set its __call__ attribute to an instance of the
1461 class. Originally fixed for classic classes, but this fix is for new-style.
1462 Removes the infinite_rec_3 crasher.

Georg Brandl24250812006-06-09 18:45:48 +00001464- The string and unicode methods startswith() and endswith() now accept
1465 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1466
Brett Cannonde3b0522006-06-08 17:00:45 +00001467- Buffer objects, at the C level, never used the char buffer
1468 implementation even when the char buffer for the wrapped object was
1469 explicitly requested (originally returned the read or write buffer).
1470 Now a TypeError is raised if the char buffer is not present but is
1471 requested.
1472
Georg Brandlddbaa662006-06-04 21:56:52 +00001473- Patch #1346214: Statements like "if 0: suite" are now again optimized
1474 away like they were in Python 2.4.
1475
Georg Brandlb7c8f542006-05-27 12:30:25 +00001476- Builtin exceptions are now full-blown new-style classes instead of
1477 instances pretending to be classes, which speeds up exception handling
1478 by about 80% in comparison to 2.5a2.
1479
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001480- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1481 Unicode 4.1.
1482
Georg Brandlf4ef1162006-05-26 18:03:31 +00001483- Patch #921466: sys.path_importer_cache is now used to cache valid and
1484 invalid file paths for the built-in import machinery which leads to
1485 fewer open calls on startup.
1486
Tim Peters696cf432006-05-24 21:10:40 +00001487- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1488 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1489 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1490 the number of input digits (it was and remains linear-time for bases
1491 2, 4, 8, 16 and 32).
1492
Tim Petersb713ec22006-05-23 18:45:30 +00001493- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1494 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1495 an integer close to ``sys.maxint``. This was repaired by patch
1496 #1335972, which also gives a nice speedup.
1497
Richard Jonescebbefc2006-05-23 18:28:17 +00001498- Patch #1337051: reduced size of frame objects.
1499
1500- PyErr_NewException now accepts a tuple of base classes as its
1501 "base" parameter.
1502
Richard Jones7c88dcc2006-05-23 10:37:38 +00001503- Patch #876206: function call speedup by retaining allocated frame
1504 objects.
1505
Georg Brandl7b90e162006-05-18 07:01:27 +00001506- Bug #1462152: file() now checks more thoroughly for invalid mode
1507 strings and removes a possible "U" before passing the mode to the
1508 C library function.
1509
Neal Norwitz1004a532006-05-15 07:17:23 +00001510- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1511
Neal Norwitz373f0a72006-05-15 07:04:36 +00001512- Bug #1487966: Fix SystemError with conditional expression in assignment
1513
Martin v. Löwis879768d2006-05-11 13:28:43 +00001514- WindowsError now has two error code attributes: errno, which carries
1515 the error values from errno.h, and winerror, which carries the error
1516 values from winerror.h. Previous versions put the winerror.h values
1517 (from GetLastError()) into the errno attribute.
1518
Martin v. Löwis77736712006-05-04 05:51:03 +00001519- Patch #1475845: Raise IndentationError for unexpected indent.
1520
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001521- Patch #1479181: split open() and file() from being aliases for each other.
1522
Tim Peters44bd9862006-06-01 13:49:23 +00001523- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1524 methods were always silently ignored by dictionaries when comparing keys.
1525 They are now passed through (except when using the C API function
1526 ``PyDict_GetItem()``, whose semantics did not change).
1527
1528- Bug #1456209: In some obscure cases it was possible for a class with a
1529 custom ``__eq__()`` method to confuse dict internals when class instances
1530 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1531 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001533Extension Modules
1534-----------------
1535
Trent Mick960a3f82006-06-28 20:30:41 +00001536- Bug #1295808: expat symbols should be namespaced in pyexpat
1537
1538- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1539
Brett Cannon6ee7d012006-06-08 16:23:04 +00001540- Change binascii.hexlify to accept a read-only buffer instead of only a char
1541 buffer and actually follow its documentation.
1542
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001543- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1544
Nick Coghlanc649ec52006-05-29 12:43:05 +00001545- Patch #1478788 (modified version): The functional extension module has
1546 been renamed to _functools and a functools Python wrapper module added.
1547 This provides a home for additional function related utilities that are
1548 not specifically about functional programming. See PEP 309.
1549
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001550- Patch #1493701: performance enhancements for struct module.
1551
Georg Brandl378d5922006-05-17 14:26:50 +00001552- Patch #1490224: time.altzone is now set correctly on Cygwin.
1553
Georg Brandl8d3342b2006-05-16 07:38:27 +00001554- Patch #1435422: zlib's compress and decompress objects now have a
1555 copy() method.
1556
Andrew MacIntyre92913322006-06-13 15:04:24 +00001557- Patch #1454481: thread stack size is now tunable at runtime for thread
1558 enabled builds on Windows and systems with Posix threads support.
1559
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001560- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1561 (up to the system limit of 32K characters).
1562
1563- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1564 As a result, these functions now raise WindowsError instead of OSError.
1565
Tim Peters7a822da2006-05-25 21:50:17 +00001566- ``time.clock()`` on Win64 should use the high-performance Windows
1567 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1568 Windows platforms).
1569
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001570- Calling Tk_Init twice is refused if the first call failed as that
1571 may deadlock.
1572
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001573- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1574 accept it without potentially using an uninitialized pointer.
1575
1576- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1577 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1578 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001579
Gregory P. Smith372b5832006-06-05 18:48:21 +00001580- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001581 [pybsddb project SF patch number 1466734]
1582
Gregory P. Smith372b5832006-06-05 18:48:21 +00001583- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1584 parameter is supplied. [SF pybsddb bug #1477863]
1585
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001586- bsddb: the __len__ method of a DB object has been fixed to return correct
1587 results. It could previously incorrectly return 0 in some cases.
1588 Fixes SF bug 1493322 (pybsddb bug 1184012).
1589
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001590- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1591 aborts the db transaction safely when a modifier callback fails.
1592 Fixes SF python patch/bug #1408584.
1593
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001594- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001595 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001596 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1597 database calls that would previously deadlock. [SF python bug #775414]
1598
Vinay Sajip28e57612006-07-01 10:45:20 +00001599- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001600
Walter Dörwald4994d952006-06-19 08:07:50 +00001601- Patch #1506645: add Python wrappers for the curses functions
1602 is_term_resized, resize_term and resizeterm.

1605-------
1606
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001607- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1608 functions.
1609
Martin v. Löwis3798da02006-06-17 18:44:27 +00001610- Patch #812986: Update turtle output even if not tracing.
1611
Vinay Sajip28e57612006-07-01 10:45:20 +00001612- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001613 Tkinter.BaseWidget.
1614
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001615- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1616
Martin v. Löwis337487e2006-06-17 09:15:14 +00001617- Patch #763580: Add name and value arguments to Tkinter variable
1618 classes.
1619
Georg Brandl83cc0d02006-06-14 08:50:03 +00001620- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1621 mime.types file for determining MIME types.
1622
Georg Brandl2605ca82006-06-14 06:08:31 +00001623- Bug #1339007: Shelf objects now don't raise an exception in their
1624 __del__ method when initialization failed.
1625
Martin v. Löwisd8251432006-06-14 05:21:04 +00001626- Patch #1455898: The MBCS codec now supports the incremental mode for
1627 double-byte encodings.
1628
Tim Peters43898b42006-06-14 04:09:25 +00001629- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1630 guarantee that adjacent triples in the return list always describe
1631 non-adjacent blocks. Previously, a pair of matching blocks could end
1632 up being described by multiple adjacent triples that formed a partition
1633 of the matching pair.
1634
Greg Ward0e0c9f42006-06-11 16:24:11 +00001635- Bug #1498146: fix optparse to handle Unicode strings in option help,
1636 description, and epilog.
1637
Greg Wardd1c797e2006-06-11 14:42:41 +00001638- Bug #1366250: minor optparse documentation error.
1639
Greg Ward7f547402006-06-11 00:40:49 +00001640- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1641 clarify docs.
1642
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001643- The wsgiref package has been added to the standard library.
1644
Nick Coghlan676725d2006-06-08 13:54:49 +00001645- The functions update_wrapper() and wraps() have been added to the functools
1646 module. These make it easier to copy relevant metadata from the original
1647 function when writing wrapper functions.
1648
Tim Petersd6a9eef2006-06-05 01:48:21 +00001649- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1650 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001651
Martin v. Löwis3f767792006-06-04 19:36:28 +00001652- Patch #1359618: Speed up charmap encoder by using a trie structure
1653 for lookup.
1654
Tim Petersd609b1a2006-06-02 23:22:51 +00001655- The functions in the ``pprint`` module now sort dictionaries by key
1656 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1657 if and only if its display required more than one line, although that
1658 wasn't documented. The new behavior increases predictability; e.g.,
1659 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1660
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001661- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1662 (thanks for J. J. Lee).
1663
Georg Brandl2b330372006-05-28 20:23:12 +00001664- Patch #1496206: improve urllib2 handling of passwords with respect to
1665 default HTTP and HTTPS ports.
1666
George Yoshidaf3c65de2006-05-28 16:39:09 +00001667- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1668
Bob Ippolito7298f272006-05-23 18:43:47 +00001669- Patch #1281707: speed up gzip.readline.
1670
Georg Brandlb89316f2006-05-17 15:51:16 +00001671- Patch #1180296: Two new functions were added to the locale module:
1672 format_string() to get the effect of "format % items" but locale-aware,
1673 and currency() to format a monetary number with currency sign.
1674
Georg Brandle3a25832006-05-17 14:56:04 +00001675- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1676 and several features added, such as speed and geometry control.
1677
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001678- Patch #1488881: add support for external file objects in bz2 compressed
1679 tarfiles.
1680
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001681- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1682 stdout arguments, making it possible to redirect input and output
1683 for remote debugging.
1684
1685- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1686 a couple of issues, notably handling of long file names using the
1687 GNU LONGNAME extension.
1688
1689- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1690 new flag when ``name`` is already the name of an option flag.
1691
1692- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1693 package.
1694
1695- Patch #1472854: make the rlcompleter.Completer class usable on non-
1696 UNIX platforms.
1697
1698- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1699
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001700- Bug #1472827: correctly escape newlines and tabs in attribute values in

1733
1734*Release date: 27-APR-2006*

1736Core and builtins
1737-----------------
1738
Thomas Heller1b046642006-04-18 18:51:06 +00001739- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1740 by converting these apis from macros into exported functions again:
1741
1742 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1743 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1744 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1746 PyRun_String Py_CompileString
1747
Martin v. Löwis45294a92006-04-18 06:24:08 +00001748- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1749
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001750- All uses of PyStructSequence_InitType have been changed to initialize
1751 the type objects only once, even if the interpreter is initialized
1752 multiple times.
1753
Neal Norwitz61546162006-04-14 05:20:28 +00001754- Bug #1454485, array.array('u') could crash the interpreter. This was
1755 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1756 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1757
1758- Py_UNICODE is unsigned. It was always documented as unsigned, but
1759 due to a bug had a signed value in previous versions.
1760
Tim Peters3a5e8b12006-04-11 01:44:07 +00001761- Patch #837242: ``id()`` of any Python object always gives a positive
1762 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1763 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001764 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001765 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001766
Tim Peters3a5e8b12006-04-11 01:44:07 +00001767 def __hash__(self):
1768 return id(self) # WRONG
1769
1770 because a hash result must be a (short) Python int but it was always
1771 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001772 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001773 was always usable as a hash value before this patch. That's no longer
1774 necessarily so.
1775
1776- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001777 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001778 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001779 #1454844)
1780
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001781- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1782 involving generators that have paused outside of any ``try`` or ``with``
1783 blocks. (In 2.5a1, a paused generator that was part of a reference
1784 cycle could not be garbage collected, regardless of whether it was
1785 paused in a ``try`` or ``with`` block.)

1799 the cachesize parameter.
1800
1801- Bug #1149413: bsddb.*open() no longer raises an exception when using
1802 a temporary db (file=None) with the 'n' flag to truncate on open.
1803
1804- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1805 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001806
Armin Rigoa9017c32006-04-19 11:50:27 +00001807- Patch #1062014: AF_UNIX sockets under Linux have a special

1812
Peter Astrand7d1d4362006-07-14 14:04:45 +00001813- Bug #1223937: subprocess.CalledProcessError reports the exit status
1814 of the process using the returncode attribute, instead of
1815 abusing errno.
1816
Tim Peters711bf302006-04-25 03:31:36 +00001817- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1818 a doctest to be skipped (the code is not run, and the expected output
1819 or exception is ignored).
1820
Nick Coghlanda2268f2006-04-24 04:37:15 +00001821- Fixed contextlib.nested to cope with exceptions being raised and
1822 caught inside exit handlers.
1823
Greg Wardab05edc2006-04-23 03:47:58 +00001824- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1825 hex, octal, or binary; add ``append_const`` action; keep going if
1826 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1827 added ``epilog`` for better help generation).
1828
Tim Peters21fbd572006-04-21 21:18:10 +00001829- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1830 called from a thread spawned as a side effect of importing a module.
1831
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001832- The pydoc module now supports documenting packages contained in
1833 .zip or .egg files.
1834
1835- The pkgutil module now has several new utility functions, such
1836 as ``walk_packages()`` to support working with packages that are either
1837 in the filesystem or zip files.
1838
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001839- The mailbox module can now modify and delete messages from
1840 mailboxes, in addition to simply reading them. Thanks to Gregory
1841 K. Johnson for writing the code, and to the 2005 Google Summer of
1842 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001843
Tim Petersc7605f22006-04-17 21:12:33 +00001844- The ``__del__`` method of class ``local`` in module ``_threading_local``

Anthony Baxtere29002c2006-04-12 12:07:31 +00001853- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1854 Windows. Bug #1469163.
1855
Phillip J. Eby47032112006-04-11 01:07:43 +00001856- The warnings, linecache, inspect, traceback, site, and doctest modules

1866
Skip Montanaro262fb922006-04-21 02:31:07 +00001867- The pstats.Stats class accepts an optional stream keyword argument to
1868 direct output to an alternate file-like object.
1869
Anthony Baxter51bcb682006-04-05 14:51:42 +00001870Build
1871-----
1872
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001873- The Makefile now has a reindent target, which runs reindent.py on
1874 the library.
1875
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001876- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001879
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001880- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1881 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001882 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001883 CXX from --with-cxx-main, see description in README.
1884
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001885- Patch #1429775: Link extension modules with the shared libpython.
1886
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001887- Fixed a libffi build problem on MIPS systems.
1888
Tim Peters8931ff12006-05-13 23:28:20 +00001889- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1890 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1891 and "%zu" for unsigned integers of type ``size_t``.
1892
Anthony Baxter51bcb682006-04-05 14:51:42 +00001893Tests
1894-----
1895
Nick Coghlanda2268f2006-04-24 04:37:15 +00001896- test_contextlib now checks contextlib.nested can cope with exceptions
1897 being raised and caught inside exit handlers.
1898
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001899- test_cmd_line now checks operation of the -m and -c command switches
1900
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001901- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1902 it separately and by hand. It also wasn't cleaning up its changes to
1903 the current Decimal context.
1904
Thomas Woutersabd08882006-04-26 15:53:30 +00001905- regrtest.py now has a -M option to run tests that test the new limits of
1906 containers, on 64-bit architectures. Running these tests is only sensible
1907 on 64-bit machines with more than two gigabytes of memory. The argument
1908 passed is the maximum amount of memory for the tests to use.

1917-------------
1918
Tim Petersb06d28c2006-05-12 01:57:59 +00001919- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1920
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001921- PEP 343: Added Context Types section to the library reference
1922 and attempted to bring other PEP 343 related documentation into
1923 line with the implementation and/or python-dev discussions.
1924
Tim Peters8dc73d22006-04-24 02:03:16 +00001925- Bug #1337990: clarified that ``doctest`` does not support examples
1926 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001929What's New in Python 2.5 alpha 1?
1930=================================
1931
Anthony Baxterebed3f62006-04-03 15:03:44 +00001932*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001933
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001934Core and builtins
1935-----------------
1936
Nick Coghlan43832302006-04-23 17:04:07 +00001937- PEP 338: -m command line switch now delegates to runpy.run_module
1938 allowing it to support modules in packages and zipfiles
1939
Martin v. Löwisc661b882006-04-20 04:54:23 +00001940- On Windows, .DLL is not an accepted file name extension for
1941 extension modules anymore; extensions are only found if they
1942 end in .PYD.
1943
Martin v. Löwisea62d252006-04-03 10:56:49 +00001944- Bug #1421664: sys.stderr.encoding is now set to the same value as
1945 sys.stdout.encoding.
1946
Neal Norwitz92e212f2006-04-03 04:48:37 +00001947- __import__ accepts keyword arguments.
1948
Georg Brandlccadf842006-03-31 18:54:53 +00001949- Patch #1460496: round() now accepts keyword arguments.
1950
Anthony Baxter262c00a2006-03-30 10:53:17 +00001951- Fixed bug #1459029 - unicode reprs were double-escaped.
1952
Hye-Shik Changd478f342006-03-23 12:32:36 +00001953- Patch #1396919: The system scope threads are reenabled on FreeBSD
1954 5.4 and later versions.
1955
Neal Norwitze98ccf62006-03-23 05:39:47 +00001956- Bug #1115379: Compiling a Unicode string with an encoding declaration
1957 now gives a SyntaxError.
1958
Georg Brandlabd1ff82006-03-18 07:59:59 +00001959- Previously, Python code had no easy way to access the contents of a
1960 cell object. Now, a ``cell_contents`` attribute has been added
1961 (closes patch #1170323).
1962
Tim Peterscf79aac2006-03-16 01:14:46 +00001963- Patch #1123430: Python's small-object allocator now returns an arena to
1964 the system ``free()`` when all memory within an arena becomes unused
1965 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1966 freed. Some applications will see a drop in virtual memory size now,
1967 especially long-running applications that, from time to time, temporarily
1968 use a large number of small objects. Note that when Python returns an
1969 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001970 platform C library will in turn return that memory to the operating system.
1971 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001972 appears to be effective at least on Microsoft C and gcc-based systems.
1973 Thanks to Evan Jones for hard work and patience.
1974
Georg Brandl533ff6f2006-03-08 18:09:27 +00001975- Patch #1434038: property() now uses the getter's docstring if there is
1976 no "doc" argument given. This makes it possible to legitimately use
1977 property() as a decorator to produce a read-only property.
1978
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001979- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1980 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1981 of requiring an int or long in slicing and a few other contexts, enabling
1982 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1983
Neal Norwitz995acdf2006-03-07 05:01:00 +00001984- Fixed various bugs reported by Coverity's Prevent tool.
1985
Brett Cannonbf364092006-03-01 04:25:17 +00001986- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1987 new exception base class, BaseException, which has a new message attribute.
1988 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1989 Raising a string exception now raises a DeprecationWarning.
1990
Thomas Woutersfb609f42006-02-28 16:37:25 +00001991- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1992 explicitly relative, using 'from .module import name' to mean 'from the same
1993 package as this module is in. Imports without dots still default to the
1994 old relative-then-absolute, unless 'from __future__ import
1995 absolute_import' is used.
1996
Brett Cannona7446e32006-02-27 23:39:10 +00001997- Properly check if 'warnings' raises an exception (usually when a filter set
1998 to "error" is triggered) when raising a warning for raising string
1999 exceptions.
2000
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002001- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002002 The name was removed from Include/code.h.
2003
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002004- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002005
Guido van Rossum1968ad32006-02-25 22:38:04 +00002006- Patch 1433928:
2007 - The copy module now "copies" function objects (as atomic objects).
2008 - dict.__getitem__ now looks for a __missing__ hook before raising
2009 KeyError.
2010
Tim Peters84ef21c2006-02-28 20:39:06 +00002011- PEP 343: with statement implemented. Needs ``from __future__ import
2012 with_statement``. Use of 'with' as a variable will generate a warning.
2013 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002014 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002015 The following objects have __context__ methods:
2016 - The built-in file type.
2017 - The thread.LockType type.
2018 - The following types defined by the threading module:
2019 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2020 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002021
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002022- Fix the encodings package codec search function to only search
2023 inside its own package. Fixes problem reported in patch #1433198.
2024
2025 Note: Codec packages should implement and register their own
2026 codec search function. PEP 100 has the details.
2027
Tim Peters9ea89d22006-06-04 03:26:02 +00002028- PEP 353: Using ``Py_ssize_t`` as the index type.
2029
2030- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2031 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2032 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2033 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2034 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002035
Neal Norwitzfc76d632006-01-10 06:03:13 +00002036- Patch #1400181, fix unicode string formatting to not use the locale.
2037 This is how string objects work. u'%f' could use , instead of .
2038 for the decimal point. Now both strings and unicode always use periods.
2039
Neal Norwitz671b9e32006-01-09 07:07:12 +00002040- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2041 configure would break checking curses.h.
2042
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002043- Bug #959576: The pwd module is now builtin. This allows Python to be
2044 built on UNIX platforms without $HOME set.
2045
Neal Norwitzc10978f2005-12-19 06:07:16 +00002046- Bug #1072182, fix some potential problems if characters are signed.
2047
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002048- Bug #889500, fix line number on SyntaxWarning for global declarations.
2049
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002050- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2051
Neal Norwitze7214a12005-12-18 05:03:17 +00002052- Support for converting hex strings to floats no longer works.
2053 This was not portable. float('0x3') now raises a ValueError.
2054
Barry Warsaw2a38a862005-12-18 01:27:35 +00002055- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002056 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002057 is now displayed in interactive prompt banner.

Georg Brandlfa166682005-12-17 21:45:17 +00002059- Implementation of PEP 341 - Unification of try/except and try/finally.
2060 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002061 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002062
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002063- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2064 now encodes backslash correctly.
2065
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002066- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2067
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002068- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002069 and long longs.
2070
Neal Norwitz67715f02005-11-09 06:59:35 +00002071- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002072 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002073 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002074
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002075- Replaced most Unicode charmap codecs with new ones using the
2076 new Unicode translate string feature in the builtin charmap
2077 codec; the codecs were created from the mapping tables available
2078 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2079 encodings now include a mapping for the Apple logo)
2080
Tim Peterse3547fd2005-12-16 23:13:57 +00002081- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002082
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002083- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002084
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002085- A new AST parser implementation was completed. The abstract
2086 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002087 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002088
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002089- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002090 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2091
Neal Norwitz708e51a2005-10-03 04:48:15 +00002092- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2093
Neal Norwitz11bd1192005-10-03 00:54:56 +00002094- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2095 Provide a warning when a directory is passed on the command line.
2096
Neal Norwitz40d37812005-10-02 01:48:49 +00002097- Fix segfault with invalid coding.
2098
2099- SF bug #772896: unknown encoding results in MemoryError.
2100
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002101- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002102 supported a __len__() method which evaluated to False when the iterator
2103 was empty.
2104
Guido van Rossum630db602005-09-20 18:49:54 +00002105- On 64-bit platforms, when __len__() returns a value that cannot be
2106 represented as a C int, raise OverflowError.
2107
Skip Montanarof8948ca2005-09-19 03:54:46 +00002108- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002109 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002110
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002111- SF bug #893549: parsing keyword arguments was broken with a few format
2112 codes.
2113
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002114- Changes donated by Elemental Security to make it work on AIX 5.3
2115 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2116 bug #105470: test_pwd fails on 64bit system (Opteron).
2117
Guido van Rossum539c6622005-09-14 17:49:54 +00002118- Changes donated by Elemental Security to make it work on HP-UX 11 on
2119 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2120
Georg Brandl4550b8d2005-08-26 06:43:52 +00002121- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002122 (fixes bug #1119418).
2123
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002124- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2125
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002126- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2127 exceptions that cause a function to exit.
2128
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002129- The implementation of set() and frozenset() was revised to use its
2130 own internal data structure. Memory consumption is reduced by 1/3
2131 and there are modest speed-ups as well. The API is unchanged.
2132
Tim Petersde7990b2005-07-17 23:45:23 +00002133- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2134
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002135- SF bug #1229429: PyObject_CallMethod failed to decrement some
2136 reference counts in some error exit cases.
2137
Tim Petersecc6e6a2005-07-10 22:30:55 +00002138- SF bug #1185883: Python's small-object memory allocator took over
2139 a block managed by the platform C library whenever a realloc specified
2140 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002141 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002142 portable way to copy data from the C-managed block into Python's
2143 small-object space without risking a memory fault. Python's small-object
2144 realloc now leaves such blocks under the control of the platform C
2145 realloc.
2146
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002147- SF bug #1232517: An overflow error was not detected properly when
2148 attempting to convert a large float to an int in os.utime().
2149
Raymond Hettinger3296e692005-06-29 23:29:56 +00002150- SF bug #1224347: hex longs now print with lowercase letters just
2151 like their int counterparts.
2152
Michael W. Hudson188d4362005-06-20 16:52:57 +00002153- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2154 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2155 interpreter states; back out that fix and do a better job (see
2156 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2157 for a longer write-up of the problem).
2158
Michael W. Hudsondf888462005-06-03 14:41:55 +00002159- SF patch #1180995: marshal now uses a binary format by default when
2160 serializing floats.
2161
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002162- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2163 the routines that promise to produce IEEE 754 binary representations
2164 of floats now simply copy bytes around.
2165
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002166- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2167 278.
2168
Brett Cannonc3647ac2005-04-26 03:45:26 +00002169- patch #1109424: int, long, float, complex, and unicode now check for the
2170 proper magic slot for type conversions when subclassed. Previously the
2171 magic slot was ignored during conversion. Semantics now match the way
2172 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002173 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002174 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002175 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002176
Barry Warsawc8d907c2005-04-19 23:43:40 +00002177- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2178 NULL, now raise an AttributeError when attempting to set or delete the
2179 attribute. Previously a TypeError was raised, but this was inconsistent
2180 with the equivalent pure-Python implementation.
2181
Michael W. Hudson774479c2005-04-18 08:46:17 +00002182- It is now safe to call PyGILState_Release() before
2183 PyEval_InitThreads() (note that if there is reason to believe there
2184 are multiple threads around you still must call PyEval_InitThreads()
2185 before using the Python API; this fix is for extension modules that
2186 have no way of knowing if Python is multi-threaded yet).
2187
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002188- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2189 disabled caused a crash.
2190
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002191- Bug #1165306: instancemethod_new allowed the creation of a method
2192 with im_class == im_self == NULL, which caused a crash when called.
2193
Tim Petersecc6e6a2005-07-10 22:30:55 +00002194- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002195 fixes the crash seen in bug #1165761
2196
Raymond Hettinger96229b12005-03-11 06:49:40 +00002197- Added two new builtins, any() and all().
2198
Brett Cannon409d8f22005-03-05 06:47:57 +00002199- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002200 (e.g., ``class C(): pass`` is no longer a syntax error).
2201 Patch #1176012 added support to the 'parser' module and 'compiler' package
2202 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002203
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002204- Patch #1115086: Support PY_LONGLONG in structmember.
2205
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002206- Bug #1155938: new style classes did not check that __init__() was
2207 returning None.
2208
Tim Petersecc6e6a2005-07-10 22:30:55 +00002209- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002210 ('\') with a specific error message.
2211
Martin v. Löwisff232d72005-03-03 09:24:38 +00002212- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2213
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002214- Bug #1124295: the __name__ attribute of file objects was
2215 inadvertently made inaccessible in restricted mode.
2216
Tim Petersecc6e6a2005-07-10 22:30:55 +00002217- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002218 an ferror() call.
2219
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002220- min() and max() now support key= arguments with the same meaning as in
2221 list.sort().
2222
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002223- The peephole optimizer now performs simple constant folding in expressions:
2224 (2+3) --> (5).
2225
Raymond Hettingera422c342005-01-11 03:03:27 +00002226- set and frozenset objects can now be marshalled. SF #1098985.
2227
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002228- Bug #1077106: Poor argument checking could cause memory corruption
2229 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002230
Jeremy Hyltonab630502005-02-04 18:44:06 +00002231- The parser did not complain about future statements in illegal
2232 positions. It once again reports a syntax error if a future
2233 statement occurs after anything other than a doc string.
2234
Neil Schemenauercf52c072005-08-12 17:34:58 +00002235- Change the %s format specifier for str objects so that it returns a
2236 unicode instance if the argument is not an instance of basestring and
2237 calling __str__ on the argument returns a unicode instance.
2238
Tim Petersf4e69282006-02-27 17:15:31 +00002239- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2240 current thread state when the auto-GIL-state machinery knows about
2241 it (since the thread state is being deleted, continuing to remember it
2242 can't help, but can hurt if another thread happens to get created with
2243 the same thread id).
2244
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002245Extension Modules
2246-----------------
2247
Georg Brandl43f08a82006-03-31 18:01:16 +00002248- Patch #1380952: fix SSL objects timing out on consecutive read()s

Georg Brandlbc45a3f2006-03-17 19:17:34 +00002257
Neal Norwitz10be10c2006-03-16 06:50:13 +00002258- Everything under lib-old was removed. This includes the following modules:
2259 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002260 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002261 util, whatsound, whrandom, zmod
2262
2263- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2264
2265- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002266 is deprecated. The undocumented re.engine variable no longer exists.
2267
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002268- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2269 SS2 (single-shift 2) escape sequences correctly.
2270
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002271- The unicodedata module was updated to the 4.1 version of the Unicode
2272 database. The 3.2 version is still available as unicodedata.db_3_2_0
2273 for applications that require this specific version (such as IDNA).
2274
Neal Norwitzb62c4332006-03-04 18:35:47 +00002275- The timing module is no longer built by default. It was deprecated
2276 in PEP 4 in Python 2.0 or earlier.
2277
Guido van Rossum1968ad32006-02-25 22:38:04 +00002278- Patch 1433928: Added a new type, defaultdict, to the collections module.
2279 This uses the new __missing__ hook behavior added to dict (see above).
2280
Georg Brandldbd83392006-02-20 09:42:33 +00002281- Bug #854823: socketmodule now builds on Sun platforms even when
2282 INET_ADDRSTRLEN is not defined.
2283
Georg Brandlf4f44152006-02-18 22:29:33 +00002284- Patch #1393157: os.startfile() now has an optional argument to specify
2285 a "command verb" to invoke on the file.
2286
Neal Norwitz082b2df2006-02-07 07:04:46 +00002287- Bug #876637, prevent stack corruption when socket descriptor
2288 is larger than FD_SETSIZE.
2289
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002290- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2291 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2292 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2293
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002294- Patch #1422385: The nis module now supports access to domains other
2295 than the system default domain.
2296
Martin v. Löwis14694662006-02-03 12:54:16 +00002297- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2298 are reported, the limit on path name lengths is removed, and stat reports
2299 WindowsError now (instead of OSError).
2300
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002301- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2302
Neal Norwitz62a21122006-01-25 05:21:55 +00002303- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
2304 before the env.
2305

2307
Neal Norwitz3b4fff82006-01-11 08:54:45 +00002308- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)
2309
Neal Norwitz88bbd732006-01-10 07:05:44 +00002310- Bug #1400822, _curses over{lay,write} doesn't work when passing 6 ints.
2311 Also fix ungetmouse() which did not accept arguments properly.
2312 The code now conforms to the documented signature.
2313
Neal Norwitz5e3d8622006-01-09 06:24:35 +00002314- Bug #1400115, Fix segfault when calling curses.panel.userptr()
2315 without prior setting of the userptr.
2316
Neal Norwitz40c6b472006-01-05 05:43:35 +00002317- Fix 64-bit problems in bsddb.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002435- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2436 been renamed to have only a single underscore prefix. This was done to
2437 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002438
Nick Coghlan43832302006-04-23 17:04:07 +00002439- PEP 338: new module runpy defines a run_module function to support
2440 executing modules which provide access to source code or a code object
2441 via the PEP 302 import mechanisms.
2442
Anthony Baxter93f5b932006-04-03 08:05:07 +00002443- The email module's parsedate_tz function now sets the daylight savings
2444 flag to -1 (unknown) since it can't tell from the date whether it should

2451 in attribute values.
2452
Anthony Baxterc51ee692006-04-01 00:57:31 +00002453- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002454 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002455 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002456 module will not be built.
2457
Tim Petersc17976e2006-04-01 00:26:53 +00002458- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2459 aren't officially supported here, and trying to use them will probably
2460 raise an exception some day. But dicts have been allowed, and "mostly
2461 worked", so support for them won't go away without warning.
2462
Georg Brandl338ef7d2006-03-31 18:42:16 +00002463- Bug #1445068: getpass.getpass() can now be given an explicit stream
2464 argument to specify where to write the prompt.
2465
Georg Brandl22ec80b2006-03-31 18:25:44 +00002466- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2473
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002474- Queue.Queue objects now support .task_done() and .join() methods
2475 to make it easier to monitor when daemon threads have completed
2476 processing all enqueued tasks. Patch #1455676.
2477

2481
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002482- email 4.0 package now integrated. This is largely the same as the email 3.0
2483 package that was included in Python 2.3, except that PEP 8 module names are
2484 now used (e.g. mail.message instead of email.Message). The MIME classes
2485 have been moved to a subpackage (e.g. email.mime.text instead of
2486 email.MIMEText). The old names are still supported for now. Several
2487 deprecated Message methods have been removed and lots of bugs have been
2488 fixed. More details can be found in the email package documentation.
2489
Walter Dörwald40108c92006-03-27 08:15:44 +00002490- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2491 (a subclass of tuple) that provides incremental decoders and encoders
2492 (a way to use stateful codecs without the stream API). Python functions
2493 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2494 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2495 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002496
Walter Dörwald067db482006-03-15 22:17:27 +00002497- Patch #1359365: Calling next() on a closed StringIO.String object raises
2498 a ValueError instead of a StopIteration now (like file and cString.String do).
2499 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2500 called before (like file and StringIO.StringIO do).

Martin v. Löwis3e865952006-01-24 15:51:21 +00002550 specifications, raises IOErrors when proxies for unsupported protocols
2551 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002574 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2575 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2576 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2577 Ronald L. Rivest offered this advice for Python:
2578
2579 "The consensus of researchers in this area (at least as
2580 expressed at the NIST Hash Function Workshop 10/31/05),
2581 is that SHA-256 is a good choice for the time being, but
2582 that research should continue, and other alternatives may
2583 arise from this research. The larger SHA's also seem OK."

2638 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002639 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002640

2663
Georg Brandl9e43acf2005-07-04 17:16:07 +00002664- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2665 as this can cause problems with apps closing all file descriptors.

2678 Bug #1224621.
2679
Raymond Hettinger68c04532005-06-10 11:05:19 +00002680- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002681 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002682 the generate_tokens() function now accepts a callable argument that
2683 terminates by raising StopIteration.
2684
Georg Brandl9166e1a2005-06-04 09:20:03 +00002685- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2686

2689
Skip Montanaro174dd222005-05-14 20:54:16 +00002690- Patch #1120353: The xmlrpclib module provides better, more transparent,

2693 class at all.
2694
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002695- distutils.commands.upload was added to support uploading distribution

2697
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002698- distutils.commands.register now encodes the data as UTF-8 before posting
2699 them to PyPI.
2700
Raymond Hettinger267b8682005-03-27 10:47:39 +00002701- decimal operator and comparison methods now return NotImplemented
2702 instead of raising a TypeError when interacting with other types. This
2703 allows other classes to implement __radd__ style methods and have them
2704 work as expected.
2705
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002706- Bug #1163325: Decimal infinities failed to hash. Attempting to
2707 hash a NaN raised an InvalidOperation instead of a TypeError.
2708
Tim Petersecc6e6a2005-07-10 22:30:55 +00002709- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2743
Guido van Rossumd0641422005-02-03 15:01:24 +00002744- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2745 disables recursive traversal through instance attributes, which can
2746 be exploited in various ways.
2747
Tim Peterse3547fd2005-12-16 23:13:57 +00002748- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002749 flags on the HTTP listening socket.
2750
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002751- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2752 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2753
Fred Drakefbdeaad2006-07-29 16:56:15 +00002754- Patches #893642, #1039083: add allow_none, encoding arguments to
2755 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002756
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002757- Bug #1110478: Revert os.environ.update to do putenv again.
2758
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002759- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2760
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002761- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2762
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002763- Enhancements to the csv module:
2764
2765 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002766 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002767 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002768 + Dialect parameter parsing has been re-implemented to improve error
2769 reporting.
2770 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2771 dictates.
2772 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002773 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002774 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002775 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2776 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002777 + reader now allows \r characters to be quoted (previously it only allowed
2778 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002779 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002780 + Dialect classes passed to the module are no longer instantiated by
2781 the module before being parsed (the former validation scheme required
2782 this, but the mechanism was unreliable).
2783 + The dialect registry now contains instances of the internal
2784 C-coded dialect type, rather than references to python objects.
2785 + the internal c-coded dialect type is now immutable.
2786 + register_dialect now accepts the same keyword dialect specifications
2787 as the reader and writer, allowing the user to register dialects
2788 without first creating a dialect class.
2789 + a configurable limit to the size of parsed fields has been added -
2790 previously, an unmatched quote character could result in the entire
2791 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002792 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002793 the parser field size limit (returning the former limit). The initial
2794 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002795 + A line_num attribute has been added to the reader object, which tracks
2796 the number of lines read from the source iterator. This is not
2797 the same as the number of records returned, as records can span
2798 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002799 + reader and writer objects were not being registered with the cyclic-GC.
2800 This has been fixed.
2801
Brett Cannone6539c42005-01-08 02:43:53 +00002802- _DummyThread objects in the threading module now delete self.__block that is
2803 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2804 lock primitives tend to be limited in number and thus should not be wasted on
2805 a _DummyThread object. Fixes bug #1089632.
2806
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002807- The imghdr module now detects Exif files.
2808
Raymond Hettinger6065d322004-12-20 23:51:53 +00002809- StringIO.truncate() now correctly adjusts the size attribute.
2810 (Bug #951915).
2811
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002812- locale.py now uses an updated locale alias table (built using
2813 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2814 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002815 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002816
Raymond Hettinger3557f422004-12-07 12:02:02 +00002817- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2818
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002819- the pickle module no longer accepts the deprecated None option in the
2820 args tuple returned by __reduce__().
2821
Brett Cannon84667c02004-12-07 03:25:18 +00002822- optparse now optionally imports gettext. This allows its use in setup.py.
2823
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002824- the pickle module no longer uses the deprecated bin parameter.
2825
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002826- the shelve module no longer uses the deprecated binary parameter.
2827
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002828- the pstats module no longer uses the deprecated ignore() method.
2829
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002830- the filecmp module no longer uses the deprecated use_statcache argument.
2831
Raymond Hettinger664347b2004-12-04 21:21:53 +00002832- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2833 extended or overridden by subclasses. Formerly, the subclassed method would
2834 be ignored by the rest of the module. (Bug #1078905).
2835
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002836- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002837 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002838
Walter Dörwald36733692004-12-22 12:50:50 +00002839- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2840 once when a size argument is given. This prevents a buffer overflow in the
2841 tokenizer with very long source lines.
2842
Barry Warsaw538561e2006-01-01 21:48:54 +00002843- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2844 immediately after creating the object, without any intervening
2845 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002846
Skip Montanaro05885812005-01-16 20:48:27 +00002847- The reconvert.quote function can now emit triple-quoted strings. The
2848 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002849
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002850- ``UserString.MutableString`` now supports negative indices in
2851 ``__setitem__`` and ``__delitem__``
2852
Greg Ward40407942005-03-05 02:53:17 +00002853- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2854 correctly.
2855
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002856- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2857 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2858 character even if the user has passed a size parameter to get a proper
2859 line ending. Remove the special handling of a "\r\n" that has been split
2860 between two lines.
2861
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002862- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2863 about illegal code points. The codec now supports PEP 293 style error
2864 handlers.
2865
Walter Dörwald78a78b02005-09-01 12:04:29 +00002866- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002867 from the input stream, so that the output is a byte string in the correct
2868 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002869
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002870- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2871 considering it exactly like a '*'.
2872
Walter Dörwald007f8df2005-10-09 19:42:27 +00002873- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2874 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002875
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002876- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2877
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002878- Patch #1413711: Certain patterns of differences were making difflib
2879 touch the recursion limit.
2880
Walter Dörwald58917a62006-03-31 15:26:22 +00002881- Bug #947906: An object oriented interface has been added to the calendar
2882 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002883 called as a script (e.g. via ``python -mcalendar``). Localized month and
2884 weekday names can be ouput (even if an exotic encoding is used) using
2885 special classes that use unicode.

2888-----
2889
Neal Norwitz602d3392006-03-31 08:21:40 +00002890- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2891 by using -mieee gcc option.
2892
Martin v. Löwis86d66262006-02-17 08:40:11 +00002893- Patch #1432345: Make python compile on DragonFly.
2894
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002895- Build support for Win64-AMD64 was added.
2896
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002897- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2898
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002899- Patch #881820: look for openpty and forkpty also in libbsd.
2900
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002901- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2902 The zlib module is now builtin on Windows.
2903
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002904- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2905
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002906- Bug #1189330: configure did not correctly determine the necessary
2907 value of LINKCC if python was built with GCC 4.0.
2908
Trent Mick8321b422005-07-26 02:29:21 +00002909- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2910 vulnerability in zlib 1.2.1 and 1.2.2.
2911
Brett Cannon08cd5982005-04-24 22:26:38 +00002912- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2913 flags that change binary compatibility. Changes were also made to
2914 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002915 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002916
Bob Ippolitoed233462005-03-29 13:47:59 +00002917- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2918 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2919 no longer exists). This configure patch makes things right.
2920
Martin v. Löwise2713be2005-03-08 15:03:08 +00002921- Bug #1158607: Build with --disable-unicode again.
2922
Brett Cannon46d96232005-02-16 00:07:19 +00002923- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2924 defined. Discovered as a result of not being able to build on OS X.
2925
Brett Cannon516592f2004-12-07 00:42:59 +00002926- setup.py now uses the directories specified in LDFLAGS using the -L option
2927 and in CPPFLAGS using the -I option for adding library and include
2928 directories, respectively, for compiling extension modules against. This has
2929 led to the core being compiled using the values in CPPFLAGS. It also removes
2930 the need for the special-casing of both DarwinPorts and Fink for darwin since
2931 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2932 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2933 Fink, ``-I/opt/local/include`` for DarwinPorts).
2934
Brett Cannon43802422005-02-10 20:48:03 +00002935- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2936 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2937 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2938 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002940C API
2941-----
2942
Tim Petersc9d78aa2006-03-26 23:27:58 +00002943- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2944 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2945 is obtained via the ``PyObject_`` family, it must be released via the
2946 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2947 always been officially true, but when Python's small-object allocator was
2948 introduced, an attempt was made to cater to a few extension modules
2949 discovered at the time that obtained memory via ``PyObject_New`` but
2950 released it via ``PyMem_DEL``. It's years later, and if such code still
2951 exists it will fail now (probably with segfaults, but calling wrong
2952 low-level memory management functions can yield many symptoms).
2953
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002954- Added a C API for set and frozenset objects.
2955
Raymond Hettinger66517482004-12-03 11:45:13 +00002956- Removed PyRange_New().
2957
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002958- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2959 mapping argument now. This string is used as a mapping table. Byte values
2960 greater than the length of the string and 0xFFFE are treated as undefined
2961 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002968
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002969- Patch #1276356: New resource "urlfetch" is implemented. This enables
2970 even impatient people to run tests that require remote files.
