708
Brett Cannon19d76c52006-09-09 07:18:44 +0000709- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

845Core and builtins
846-----------------
847
Neal Norwitz24b6f202006-09-05 04:43:56 +0000848- Fix infinite recursion when subclassing long and overriding __hash__.
849
850- Fix concatenation (+=) of long strings.
851
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000852- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000853 compared equal or unequal to a string and a UnicodeDecodeError
854 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000855
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000856 Instead, the equal (==) and unequal (!=) comparison operators will
857 now issue a UnicodeWarning and interpret the two objects as
858 unequal. The UnicodeWarning can be filtered as desired using
859 the warning framework, e.g. silenced completely, turned into an
860 exception, logged, etc.
861
862 Note that compare operators other than equal and unequal will still
863 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000864
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000865- Fix segfault when doing string formatting on subclasses of long.
866
867- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines

869
870- Fix bug related to __len__ functions returning negative values with
871 classic classes.
872
873- Patch #1538606, Fix __index__() clipping. There were some problems
874 discovered with the API and how integers that didn't fit into Py_ssize_t
875 were handled. This patch attempts to provide enough alternatives
876 to effectively use __index__.
877
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000878- Bug #1536021: __hash__ may now return long int; the final hash
879 value is obtained by invoking hash on the long int.
880
Thomas Hellerab1049c2006-08-08 17:37:00 +0000881- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Thomas Heller74d36f02006-08-04 18:17:40 +0000886- On Windows, the PyErr_Warn function is now exported from
887 the Python dll again.
888
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000889- Bug #1191458: tracing over for loops now produces a line event
890 on each iteration. Fixing this problem required changing the .pyc
891 magic number. This means that .pyc files generated before 2.5c1
892 will be regenerated.
893
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000894- Bug #1333982: string/number constants were inappropriately stored
895 in the byte code and co_consts even if they were not used, ie
896 immediately popped off the stack.
897
Georg Brandle9462c72006-08-04 18:03:37 +0000898- Fixed a reference-counting problem in property().

901Library
902-------
903
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000904- Fix a bug in the ``compiler`` package that caused invalid code to be
905 generated for generator expressions.
906
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000907- The distutils version has been changed to 2.5.0. The change to
908 keep it programmatically in sync with the Python version running
909 the code (introduced in 2.5b3) has been reverted. It will continue
910 to be maintained manually as static string literal.
911
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000912- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000913 and this cannot be converted to the required C type, an exception is
914 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000915 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000916
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000917- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000918 an exception.
919
Tim Peterscbdd3502006-09-05 01:47:53 +0000920- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000921 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000922 workarounds for clocks with low resolution, to stop the code yielding
923 duplicate UUIDs.
924
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000925- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
926 before raising SystemExit, allowing IDLE to honor quit() and exit().
927
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000928- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
929
Georg Brandl7a1af772006-08-14 21:55:28 +0000930- Patch #1536071: trace.py should now find the full module name of a
931 file correctly even on Windows.
932
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000933- logging's atexit hook now runs even if the rest of the module has
934 already been cleaned up.
935
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000936- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000937
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000938- Bug #1531405, format_exception no longer raises an exception if
939 str(exception) raised an exception.
940
Neil Schemenauer06ded092006-08-04 16:20:30 +0000941- Fix a bug in the ``compiler`` package that caused invalid code to be
942 generated for nested functions.
943
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000944

951
Georg Brandl3335a7a2006-08-14 21:42:55 +0000952- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
953 raises the correct exceptions.
954
Thomas Heller1ce433e2006-08-14 16:20:04 +0000955- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
956 '-no-stack-protector' compiler flag for OpenBSD has been removed.
957
Thomas Heller86720042006-08-14 11:17:48 +0000958- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
959 uses the _as_parameter_ attribute when objects are passed to foreign
960 function calls. The ctypes version number was changed to 1.0.1.
961
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000962- Bug #1530559, struct.pack raises TypeError where it used to convert.
963 Passing float arguments to struct.pack when integers are expected
964 now triggers a DeprecationWarning.
965
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000966

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000990- Bug #1535502, build _hashlib on Windows, and use masm assembler
991 code in OpenSSL.
992
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000993- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Tim Peters4643c2f2006-08-10 22:45:34 +0000998C API
999-----
1000
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001001- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1002
Tim Peters4643c2f2006-08-10 22:45:34 +00001003- Bug #1069160. Internal correctness changes were made to
1004 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1005 the documentation was changed to state that the return value
1006 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001009What's New in Python 2.5 beta 3?
1010================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001011
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001012*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001013
1014Core and builtins
1015-----------------
1016
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001017- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001018 returned a long (see PEP 353).
1019
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001020- Bug #1515471: string.replace() accepts character buffers again.
1021
Neal Norwitz07aadb12006-07-30 06:55:48 +00001022- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1023 This provides the proper warning for struct.pack().
1024 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1025
Neal Norwitz0d62a062006-07-30 06:53:31 +00001026- Patch #1531113: Fix augmented assignment with yield expressions.
1027 Also fix a SystemError when trying to assign to yield expressions.
1028
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001029- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1030 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1031 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1032 excessive filesystem operations during imports.
1033
Tim Petersbc24eee2006-07-27 01:14:53 +00001034- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1035 operations on signed longs that are formally undefined by C.
1036 Unfortunately, at least one compiler now cares about that, so complicated
1037 the code to make that compiler happy again.
1038
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001039- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1040
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001041- Patch #1232023: Stop including current directory in search
1042 path on Windows.
1043
Neal Norwitze1fdb322006-07-21 05:32:28 +00001044- Fix some potential crashes found with failmalloc.
1045
Neal Norwitze7563102006-07-17 01:00:16 +00001046- Fix warnings reported by Klocwork's static analysis tool.
1047
Neal Norwitz84be93b2006-07-16 01:50:38 +00001048- Bug #1512814, Fix incorrect lineno's when code within a function
1049 had more than 255 blank lines.
1050
Georg Brandl9dceedb2006-07-12 15:31:17 +00001051- Patch #1521179: Python now accepts the standard options ``--help`` and
1052 ``--version`` as well as ``/?`` on Windows.
1053
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001054- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001055 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001056 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001057
Tim Peters112aad32006-07-19 00:03:19 +00001058- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001059 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001060 new ``sys._current_frames()`` returns a dictionary with one entry,
1061 mapping the faux "thread id" 0 to the current frame.
1062
Ronald Oussoren3075e162006-07-25 20:28:55 +00001063- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001064
Ronald Oussoren3075e162006-07-25 20:28:55 +00001065
Neal Norwitza1f10902006-07-12 07:28:29 +00001066Library
1067-------
1068
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001069- Correction of patch #1455898: In the mbcs decoder, set final=False
1070 for stream decoder, but final=True for the decode function.
1071
Georg Brandl07fec3a2006-08-01 18:49:24 +00001072- os.urandom no longer masks unrelated exceptions like SystemExit or
1073 KeyboardInterrupt.
1074
Tim Peters4643c2f2006-08-10 22:45:34 +00001075- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001076 shutil.copytree on Windows
1077
Georg Brandle34ac7c2006-07-30 11:07:23 +00001078- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1079 refers to file descriptors, not file objects.
1080
Tim Peterscbdd3502006-09-05 01:47:53 +00001081- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001082 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001083 #1513611, and probably others.
1084
Georg Brandledd9b0d2006-07-29 09:33:26 +00001085- Bug #1441397: The compiler module now recognizes module and function
1086 docstrings correctly as it did in Python 2.4.
1087
Tim Peters6f681472006-07-27 23:44:37 +00001088- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1089 lost that tests are sorted by name before being run. This rarely
1090 matters for well-written tests, but can create baffling symptoms if
1091 side effects from one test to the next affect outcomes. ``DocTestFinder``
1092 has been changed to sort the list of tests it returns.
1093
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001094- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001095 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001096
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001097- Bug #978833: Really close underlying socket in _socketobject.close.
1098
Georg Brandldb232dc2006-08-20 13:15:43 +00001099- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1100 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001101
Georg Brandlcf0c1722006-07-26 07:23:32 +00001102- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1103 to recursive calls and call it with the failing package name.
1104
Martin v. Löwis0b483032006-07-25 09:53:12 +00001105- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1106
Georg Brandlc13c34c2006-07-24 14:09:56 +00001107- Patch #1515343: Fix printing of deprecated string exceptions with a
1108 value in the traceback module.
1109
Greg Ward48fae7a2006-07-23 16:05:51 +00001110- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1111
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001112- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1113
Brett Cannoncaebe222006-07-18 04:41:36 +00001114- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1115 argument tuple. For arguments where zero is illegal, the value is forced to
1116 the minimum value that is correct. This is to support an undocumented but
1117 common way people used to fill in inconsequential information in the time
1118 tuple pre-2.4.
1119
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001120- Patch #1220874: Update the binhex module for Mach-O.
1121
Barry Warsawb110bad2006-07-21 14:51:07 +00001122- The email package has improved RFC 2231 support, specifically for
1123 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1124 (name*0=<blah>) parameter continuations. This may change the types of
1125 values returned from email.message.Message.get_param() and friends.
1126 Specifically in some cases where non-encoded continuations were used,
1127 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1128 will just return the string (since non-encoded continuations don't have
1129 charset and language parts).
1130
1131 Also, whereas % values were decoded in all parameter continuations, they are
1132 now only decoded in encoded parameter parts.
1133
Ronald Oussoren3075e162006-07-25 20:28:55 +00001134- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1135
1136- Bug #1517996: IDLE now longer shows the default Tk menu when a
1137 path browser, class browser or debugger is the frontmost window on MacOS X
1138
Barry Warsaw00decd72006-07-27 23:43:15 +00001139- Patch #1520294: Support for getset and member descriptors in types.py,
1140 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1141 of an object against these built-in types and more importantly, for getting
1142 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001145Extension Modules
1146-----------------
1147
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001148- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1149 a socket operation on a socket with a timeout, the exception will be
1150 caught correctly. Previously, the exception was not caught.
1151
Thomas Heller1393d6a2006-07-28 21:43:20 +00001152- Patch #1529514: The _ctypes extension is now compiled on more
1153 openbsd target platforms.
1154
Tim Peters9cab5932006-07-28 00:30:00 +00001155- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1156 a memory leak, affecting pickles and deep copies.
1157
Tim Petersbc24eee2006-07-27 01:14:53 +00001158- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001159 Paul Eggert.
1160
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001161- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1162
Thomas Hellerce049a02006-07-14 17:51:14 +00001163- Patch #1521817: Index range checking on ctypes arrays containing
1164 exactly one element enabled again. This allows iterating over these
1165 arrays, without the need to check the array size before.
1166
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001167- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001168 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001169 /dev/null in certain cases; this is now fixed.
1170
Thomas Heller47d7a062006-07-12 08:43:47 +00001171- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1172 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001173
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001174- Because of a misspelled preprocessor symbol, ctypes was always
1175 compiled without thread support; this is now fixed.
1176
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001177- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1178 methods now allow their database parameter to be None as the
1179 sleepycat API allows.
1180
Matt Flemingec926502006-07-28 11:27:27 +00001181- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1182 bluetooth API compared with Linux and FreeBSD.
1183
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001184Tests
1185-----
1186
1187- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1188 how long the test file should take to play. Now accepts taking 2.93 secs
1189 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1190
Georg Brandl4793aa32006-07-28 18:31:39 +00001191- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1192 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1193 run via ``regrtest.py``. Now they do.

Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001195Build
1196-----
1197
1198- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1199
Ronald Oussoren26cad082006-08-01 21:00:57 +00001200Mac
1201---
1202
1203- PythonLauncher now works correctly when the path to the script contains
1204 characters that are treated specially by the shell (such as quotes).
1205
1206- Bug #1527397: PythonLauncher now launches scripts with the working directory
1207 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001208 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001209 expect.

1217Core and builtins
1218-----------------
1219
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001220- Bug #1441486: The literal representation of -(sys.maxint - 1)
1221 again evaluates to a int object, not a long.
1222
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001223- Bug #1501934: The scope of global variables that are locally assigned
1224 using augmented assignment is now correctly determined.
1225
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001226- Bug #927248: Recursive method-wrapper objects can now safely
1227 be released.
1228
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001229- Bug #1417699: Reject locale-specific decimal point in float()
1230 and atof().
1231
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001232- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1233 omit a default "error" argument for NULL pointer. This allows
1234 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001235
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001236- Bug #1519018: 'as' is now validated properly in import statements.
1237
Neal Norwitz28746ab2006-07-09 22:14:42 +00001238- On 64 bit systems, int literals that use less than 64 bits are
1239 now ints rather than longs.
1240
Neal Norwitzed657552006-07-10 00:04:44 +00001241- Bug #1512814, Fix incorrect lineno's when code at module scope
1242 started after line 256.
1243
Tim Peters32a83612006-07-10 21:08:24 +00001244- New function ``sys._current_frames()`` returns a dict mapping thread
1245 id to topmost thread stack frame. This is for expert use, and is
1246 especially useful for debugging application deadlocks. The functionality
1247 was previously available in Fazal Majid's ``threadframe`` extension
1248 module, but it wasn't possible to do this in a wholly threadsafe way from
1249 an extension.
1250

1253
Martin v. Löwis77621582006-07-30 13:27:31 +00001254- Bug #1257728: Mention Cygwin in distutils error message about a missing
1255 VS 2003.
1256
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001257- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1258
Tim Peters32a83612006-07-10 21:08:24 +00001259- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001260 environment variable to be set in order to the SDK environment
1261 for finding the compiler, include files, etc.
1262
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001263- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1264
Nick Coghlan2d792252006-07-06 13:47:18 +00001265- warnings.py now ignores ImportWarning by default
1266
Thomas Woutersadd19112006-07-05 11:03:49 +00001267- string.Template() now correctly handles tuple-values. Previously,
1268 multi-value tuples would raise an exception and single-value tuples would
1269 be treated as the value they contain, instead.
1270
Martin v. Löwisede77f52006-07-03 13:01:35 +00001271- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1272 even if some data are received.
1273
Martin v. Löwis45482392006-07-03 12:28:58 +00001274- Bug #1267547: Put proper recursive setup.py call into the
1275 spec file generated by bdist_rpm.
1276
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001277- Bug #1514693: Update turtle's heading when switching between
1278 degrees and radians.
1279
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001280- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001281 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001282
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001283- Bug #1514703: Only setup canvas window in turtle when the canvas
1284 is created.
1285
Martin v. Löwis7596e832006-07-01 15:33:37 +00001286- Bug #1513223: .close() of a _socketobj now releases the underlying
1287 socket again, which then gets closed as it becomes unreferenced.

1290 attribute values.
1291
1292- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1293 sgmllib ('[' and ']' were not accepted).
1294
Georg Brandl1be63af2006-06-28 20:23:25 +00001295- Fix a bug in the turtle module's end_fill function.
1296
Brett Cannon53ab5b72006-06-22 16:49:14 +00001297- Bug #1510580: The 'warnings' module improperly required that a Warning
1298 category be either a types.ClassType and a subclass of Warning. The proper
1299 check is just that it is a subclass with Warning as the documentation states.
1300
Georg Brandlad29e632006-06-21 17:45:17 +00001301- The compiler module now correctly compiles the new try-except-finally
1302 statement (bug #1509132).
1303
Neal Norwitz60373cd2006-06-22 06:30:50 +00001304- The wsgiref package is now installed properly on Unix.
1305
Vinay Sajip28e57612006-07-01 10:45:20 +00001306- A bug was fixed in logging.config.fileConfig() which caused a crash on
1307 shutdown when fileConfig() was called multiple times.
1308
Gerhard Häring762fbd32006-07-02 17:48:30 +00001309- The sqlite3 module did cut off data from the SQLite database at the first
1310 null character before sending it to a custom converter. This has been fixed
1311 now.
1312
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001313Extension Modules
1314-----------------
1315
Tim Peters112aad32006-07-19 00:03:19 +00001316- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1317 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1318 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001319
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001320- Assigning None to pointer type fields in ctypes structures possible
1321 overwrote the wrong fields, this is fixed now.
1322
1323- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1324 on non-Windows platforms.
1325
1326- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1327 integer or long, without range checking.
1328
1329- Patch #1517790: It is now possible to use custom objects in the ctypes
1330 foreign function argtypes sequence as long as they provide a from_param
1331 method, no longer is it required that the object is a ctypes type.
1332
1333- The '_ctypes' extension module now works when Python is configured
1334 with the --without-threads option.
1335
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001336- Bug #1513646: os.access on Windows now correctly determines write
1337 access, again.
1338
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001339- Bug #1512695: cPickle.loads could crash if it was interrupted with
1340 a KeyboardInterrupt.
1341
Neal Norwitza12aa882006-07-06 06:45:08 +00001342- Bug #1296433: parsing XML with a non-default encoding and
1343 a CharacterDataHandler could crash the interpreter in pyexpat.
1344
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001345- Patch #1516912: improve Modules support for OpenVMS.
1346
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001347Build
1348-----
1349
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001350- Automate Windows build process for the Win64 SSL module.
1351
Tim Peters32a83612006-07-10 21:08:24 +00001352- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001353 Previously, the slight difference could cause compilation errors of the
1354 'zlib' module on systems with more than one version of zlib.
1355
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001356- The MSI compileall step was fixed to also support a TARGETDIR
1357 with spaces in it.
1358
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001359- Bug #1517388: sqlite3.dll is now installed on Windows independent
1360 of Tcl/Tk.
1361
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001362- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001363 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001364
Neal Norwitzb15ac312006-06-29 04:10:08 +00001365Tests
1366-----
1367
1368- Call os.waitpid() at the end of tests that spawn child processes in order
1369 to minimize resources (zombies).
1370
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001371Documentation
1372-------------
1373
Nick Coghlan2d792252006-07-06 13:47:18 +00001374- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1375 documentation for the warnings module.
1376
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001377- Patch #1509163: MS Toolkit Compiler no longer available.
1378
Neal Norwitz56640df2006-07-10 02:36:41 +00001379- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001386
1387Core and builtins
1388-----------------
1389
Georg Brandla56b9152006-06-19 06:35:54 +00001390- Patch #1507676: Error messages returned by invalid abstract object operations
1391 (such as iterating over an integer) have been improved and now include the
1392 type of the offending object to help with debugging.
1393
Brett Cannonea3912b2006-06-13 21:46:41 +00001394- Bug #992017: A classic class that defined a __coerce__() method that returned
1395 its arguments swapped would infinitely recurse and segfault the interpreter.
1396
Neal Norwitz909eb122006-06-12 02:13:21 +00001397- Fix the socket tests so they can be run concurrently.
1398
Neal Norwitzb9845e72006-06-12 02:11:18 +00001399- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001400 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001401
Brett Cannon22565aa2006-06-09 22:31:23 +00001402- Bug #532646: object.__call__() will continue looking for the __call__
1403 attribute on objects until one without one is found. This leads to recursion
1404 when you take a class and set its __call__ attribute to an instance of the
1405 class. Originally fixed for classic classes, but this fix is for new-style.
1406 Removes the infinite_rec_3 crasher.
1407
Georg Brandl24250812006-06-09 18:45:48 +00001408- The string and unicode methods startswith() and endswith() now accept
1409 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1410
Brett Cannonde3b0522006-06-08 17:00:45 +00001411- Buffer objects, at the C level, never used the char buffer
1412 implementation even when the char buffer for the wrapped object was
1413 explicitly requested (originally returned the read or write buffer).
1414 Now a TypeError is raised if the char buffer is not present but is
1415 requested.
1416
Georg Brandlddbaa662006-06-04 21:56:52 +00001417- Patch #1346214: Statements like "if 0: suite" are now again optimized
1418 away like they were in Python 2.4.
1419
Georg Brandlb7c8f542006-05-27 12:30:25 +00001420- Builtin exceptions are now full-blown new-style classes instead of
1421 instances pretending to be classes, which speeds up exception handling
1422 by about 80% in comparison to 2.5a2.
1423
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001424- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1425 Unicode 4.1.
1426
Georg Brandlf4ef1162006-05-26 18:03:31 +00001427- Patch #921466: sys.path_importer_cache is now used to cache valid and
1428 invalid file paths for the built-in import machinery which leads to
1429 fewer open calls on startup.
1430
Tim Peters696cf432006-05-24 21:10:40 +00001431- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1432 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1433 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1434 the number of input digits (it was and remains linear-time for bases
1435 2, 4, 8, 16 and 32).
1436
Tim Petersb713ec22006-05-23 18:45:30 +00001437- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1438 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1439 an integer close to ``sys.maxint``. This was repaired by patch
1440 #1335972, which also gives a nice speedup.
1441
Richard Jonescebbefc2006-05-23 18:28:17 +00001442- Patch #1337051: reduced size of frame objects.
1443
1444- PyErr_NewException now accepts a tuple of base classes as its
1445 "base" parameter.
1446
Richard Jones7c88dcc2006-05-23 10:37:38 +00001447- Patch #876206: function call speedup by retaining allocated frame
1448 objects.
1449
Georg Brandl7b90e162006-05-18 07:01:27 +00001450- Bug #1462152: file() now checks more thoroughly for invalid mode
1451 strings and removes a possible "U" before passing the mode to the
1452 C library function.
1453
Neal Norwitz1004a532006-05-15 07:17:23 +00001454- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1455
Neal Norwitz373f0a72006-05-15 07:04:36 +00001456- Bug #1487966: Fix SystemError with conditional expression in assignment
1457
Martin v. Löwis879768d2006-05-11 13:28:43 +00001458- WindowsError now has two error code attributes: errno, which carries
1459 the error values from errno.h, and winerror, which carries the error
1460 values from winerror.h. Previous versions put the winerror.h values
1461 (from GetLastError()) into the errno attribute.
1462
Martin v. Löwis77736712006-05-04 05:51:03 +00001463- Patch #1475845: Raise IndentationError for unexpected indent.
1464
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001465- Patch #1479181: split open() and file() from being aliases for each other.
1466
Tim Peters44bd9862006-06-01 13:49:23 +00001467- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1468 methods were always silently ignored by dictionaries when comparing keys.
1469 They are now passed through (except when using the C API function
1470 ``PyDict_GetItem()``, whose semantics did not change).
1471
1472- Bug #1456209: In some obscure cases it was possible for a class with a
1473 custom ``__eq__()`` method to confuse dict internals when class instances
1474 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1475 No, you don't have any code that did this ;-)

1478-----------------
1479
Trent Mick960a3f82006-06-28 20:30:41 +00001480- Bug #1295808: expat symbols should be namespaced in pyexpat
1481
1482- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1483
Brett Cannon6ee7d012006-06-08 16:23:04 +00001484- Change binascii.hexlify to accept a read-only buffer instead of only a char
1485 buffer and actually follow its documentation.
1486
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001487- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1488
Nick Coghlanc649ec52006-05-29 12:43:05 +00001489- Patch #1478788 (modified version): The functional extension module has
1490 been renamed to _functools and a functools Python wrapper module added.
1491 This provides a home for additional function related utilities that are
1492 not specifically about functional programming. See PEP 309.
1493
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001494- Patch #1493701: performance enhancements for struct module.
1495
Georg Brandl378d5922006-05-17 14:26:50 +00001496- Patch #1490224: time.altzone is now set correctly on Cygwin.
1497
Georg Brandl8d3342b2006-05-16 07:38:27 +00001498- Patch #1435422: zlib's compress and decompress objects now have a
1499 copy() method.
1500
Andrew MacIntyre92913322006-06-13 15:04:24 +00001501- Patch #1454481: thread stack size is now tunable at runtime for thread
1502 enabled builds on Windows and systems with Posix threads support.
1503
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001504- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1505 (up to the system limit of 32K characters).
1506
1507- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1508 As a result, these functions now raise WindowsError instead of OSError.
1509
Tim Peters7a822da2006-05-25 21:50:17 +00001510- ``time.clock()`` on Win64 should use the high-performance Windows
1511 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1512 Windows platforms).
1513
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001514- Calling Tk_Init twice is refused if the first call failed as that
1515 may deadlock.
1516
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001517- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1518 accept it without potentially using an uninitialized pointer.
1519
1520- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1521 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1522 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001523
Gregory P. Smith372b5832006-06-05 18:48:21 +00001524- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001525 [pybsddb project SF patch number 1466734]
1526
Gregory P. Smith372b5832006-06-05 18:48:21 +00001527- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1528 parameter is supplied. [SF pybsddb bug #1477863]
1529
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001530- bsddb: the __len__ method of a DB object has been fixed to return correct
1531 results. It could previously incorrectly return 0 in some cases.
1532 Fixes SF bug 1493322 (pybsddb bug 1184012).
1533
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001534- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1535 aborts the db transaction safely when a modifier callback fails.
1536 Fixes SF python patch/bug #1408584.
1537
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001538- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001539 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001540 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1541 database calls that would previously deadlock. [SF python bug #775414]
1542
Vinay Sajip28e57612006-07-01 10:45:20 +00001543- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001544
Walter Dörwald4994d952006-06-19 08:07:50 +00001545- Patch #1506645: add Python wrappers for the curses functions
1546 is_term_resized, resize_term and resizeterm.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001551- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1552 functions.
1553
Martin v. Löwis3798da02006-06-17 18:44:27 +00001554- Patch #812986: Update turtle output even if not tracing.
1555
Vinay Sajip28e57612006-07-01 10:45:20 +00001556- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001557 Tkinter.BaseWidget.
1558
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001559- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1560
Martin v. Löwis337487e2006-06-17 09:15:14 +00001561- Patch #763580: Add name and value arguments to Tkinter variable
1562 classes.
1563
Georg Brandl83cc0d02006-06-14 08:50:03 +00001564- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1565 mime.types file for determining MIME types.
1566
Georg Brandl2605ca82006-06-14 06:08:31 +00001567- Bug #1339007: Shelf objects now don't raise an exception in their
1568 __del__ method when initialization failed.
1569
Martin v. Löwisd8251432006-06-14 05:21:04 +00001570- Patch #1455898: The MBCS codec now supports the incremental mode for
1571 double-byte encodings.
1572
Tim Peters43898b42006-06-14 04:09:25 +00001573- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1574 guarantee that adjacent triples in the return list always describe
1575 non-adjacent blocks. Previously, a pair of matching blocks could end
1576 up being described by multiple adjacent triples that formed a partition
1577 of the matching pair.
1578
Greg Ward0e0c9f42006-06-11 16:24:11 +00001579- Bug #1498146: fix optparse to handle Unicode strings in option help,
1580 description, and epilog.
1581
Greg Wardd1c797e2006-06-11 14:42:41 +00001582- Bug #1366250: minor optparse documentation error.
1583
Greg Ward7f547402006-06-11 00:40:49 +00001584- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1585 clarify docs.
1586
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001587- The wsgiref package has been added to the standard library.
1588
Nick Coghlan676725d2006-06-08 13:54:49 +00001589- The functions update_wrapper() and wraps() have been added to the functools
1590 module. These make it easier to copy relevant metadata from the original
1591 function when writing wrapper functions.
1592
Tim Petersd6a9eef2006-06-05 01:48:21 +00001593- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1594 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001595
Martin v. Löwis3f767792006-06-04 19:36:28 +00001596- Patch #1359618: Speed up charmap encoder by using a trie structure
1597 for lookup.
1598
Tim Petersd609b1a2006-06-02 23:22:51 +00001599- The functions in the ``pprint`` module now sort dictionaries by key
1600 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1601 if and only if its display required more than one line, although that
1602 wasn't documented. The new behavior increases predictability; e.g.,
1603 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1604
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001605- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1606 (thanks for J. J. Lee).
1607
Georg Brandl2b330372006-05-28 20:23:12 +00001608- Patch #1496206: improve urllib2 handling of passwords with respect to
1609 default HTTP and HTTPS ports.
1610
George Yoshidaf3c65de2006-05-28 16:39:09 +00001611- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1612
Bob Ippolito7298f272006-05-23 18:43:47 +00001613- Patch #1281707: speed up gzip.readline.
1614
Georg Brandlb89316f2006-05-17 15:51:16 +00001615- Patch #1180296: Two new functions were added to the locale module:
1616 format_string() to get the effect of "format % items" but locale-aware,
1617 and currency() to format a monetary number with currency sign.
1618
Georg Brandle3a25832006-05-17 14:56:04 +00001619- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1620 and several features added, such as speed and geometry control.
1621
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001622- Patch #1488881: add support for external file objects in bz2 compressed
1623 tarfiles.
1624
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001625- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1626 stdout arguments, making it possible to redirect input and output
1627 for remote debugging.
1628
1629- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1630 a couple of issues, notably handling of long file names using the
1631 GNU LONGNAME extension.
1632
1633- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1634 new flag when ``name`` is already the name of an option flag.
1635
1636- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1637 package.
1638
1639- Patch #1472854: make the rlcompleter.Completer class usable on non-
1640 UNIX platforms.
1641
1642- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1643
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001644- Bug #1472827: correctly escape newlines and tabs in attribute values in
1645 the saxutils.XMLGenerator class.

1680Core and builtins
1681-----------------
1682
Thomas Heller1b046642006-04-18 18:51:06 +00001683- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1684 by converting these apis from macros into exported functions again:
1685
1686 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1687 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1688 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1689 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1690 PyRun_String Py_CompileString
1691
Martin v. Löwis45294a92006-04-18 06:24:08 +00001692- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1693
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001694- All uses of PyStructSequence_InitType have been changed to initialize
1695 the type objects only once, even if the interpreter is initialized
1696 multiple times.
1697
Neal Norwitz61546162006-04-14 05:20:28 +00001698- Bug #1454485, array.array('u') could crash the interpreter. This was
1699 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1700 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1701
1702- Py_UNICODE is unsigned. It was always documented as unsigned, but
1703 due to a bug had a signed value in previous versions.
1704
Tim Peters3a5e8b12006-04-11 01:44:07 +00001705- Patch #837242: ``id()`` of any Python object always gives a positive
1706 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1707 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001708 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001709 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001710
Tim Peters3a5e8b12006-04-11 01:44:07 +00001711 def __hash__(self):
1712 return id(self) # WRONG
1713
1714 because a hash result must be a (short) Python int but it was always
1715 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001716 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001717 was always usable as a hash value before this patch. That's no longer
1718 necessarily so.
1719
1720- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001721 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001722 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001723 #1454844)
1724
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001725- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1726 involving generators that have paused outside of any ``try`` or ``with``
1727 blocks. (In 2.5a1, a paused generator that was part of a reference
1728 cycle could not be garbage collected, regardless of whether it was
1729 paused in a ``try`` or ``with`` block.)

1735 is a macro.
1736
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001737- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1738 fails with an error condition.
1739
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001740- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1741
1742- Bug #1117761: bsddb.*open() no longer raises an exception when using
1743 the cachesize parameter.
1744
1745- Bug #1149413: bsddb.*open() no longer raises an exception when using
1746 a temporary db (file=None) with the 'n' flag to truncate on open.
1747
1748- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1749 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001750
Armin Rigoa9017c32006-04-19 11:50:27 +00001751- Patch #1062014: AF_UNIX sockets under Linux have a special
1752 abstract namespace that is now fully supported.

1755-------
1756
Peter Astrand7d1d4362006-07-14 14:04:45 +00001757- Bug #1223937: subprocess.CalledProcessError reports the exit status
1758 of the process using the returncode attribute, instead of
1759 abusing errno.
1760
Tim Peters711bf302006-04-25 03:31:36 +00001761- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1762 a doctest to be skipped (the code is not run, and the expected output
1763 or exception is ignored).
1764
Nick Coghlanda2268f2006-04-24 04:37:15 +00001765- Fixed contextlib.nested to cope with exceptions being raised and
1766 caught inside exit handlers.
1767
Greg Wardab05edc2006-04-23 03:47:58 +00001768- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1769 hex, octal, or binary; add ``append_const`` action; keep going if
1770 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1771 added ``epilog`` for better help generation).
1772
Tim Peters21fbd572006-04-21 21:18:10 +00001773- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1774 called from a thread spawned as a side effect of importing a module.
1775
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001776- The pydoc module now supports documenting packages contained in
1777 .zip or .egg files.
1778
1779- The pkgutil module now has several new utility functions, such
1780 as ``walk_packages()`` to support working with packages that are either
1781 in the filesystem or zip files.
1782
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001783- The mailbox module can now modify and delete messages from
1784 mailboxes, in addition to simply reading them. Thanks to Gregory
1785 K. Johnson for writing the code, and to the 2005 Google Summer of
1786 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001787

1799
Phillip J. Eby47032112006-04-11 01:07:43 +00001800- The warnings, linecache, inspect, traceback, site, and doctest modules
1801 were updated to work correctly with modules imported from zipfiles or
1802 via other PEP 302 __loader__ objects.
1803

1810
Skip Montanaro262fb922006-04-21 02:31:07 +00001811- The pstats.Stats class accepts an optional stream keyword argument to
1812 direct output to an alternate file-like object.
1813
Anthony Baxter51bcb682006-04-05 14:51:42 +00001814Build
1815-----
1816
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001817- The Makefile now has a reindent target, which runs reindent.py on
1818 the library.
1819
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001820- Patch #1470875: Building Python with MS Free Compiler
1821
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001822- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001823
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001824- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1825 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001826 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001827 CXX from --with-cxx-main, see description in README.
1828
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001829- Patch #1429775: Link extension modules with the shared libpython.
1830
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001831- Fixed a libffi build problem on MIPS systems.
1832
Tim Peters8931ff12006-05-13 23:28:20 +00001833- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1834 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1835 and "%zu" for unsigned integers of type ``size_t``.
1836
Anthony Baxter51bcb682006-04-05 14:51:42 +00001837Tests
1838-----
1839
Nick Coghlanda2268f2006-04-24 04:37:15 +00001840- test_contextlib now checks contextlib.nested can cope with exceptions
1841 being raised and caught inside exit handlers.
1842
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001843- test_cmd_line now checks operation of the -m and -c command switches
1844
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001845- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1846 it separately and by hand. It also wasn't cleaning up its changes to
1847 the current Decimal context.
1848
Thomas Woutersabd08882006-04-26 15:53:30 +00001849- regrtest.py now has a -M option to run tests that test the new limits of
1850 containers, on 64-bit architectures. Running these tests is only sensible
1851 on 64-bit machines with more than two gigabytes of memory. The argument
1852 passed is the maximum amount of memory for the tests to use.

1861-------------
1862
Tim Petersb06d28c2006-05-12 01:57:59 +00001863- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1864
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001865- PEP 343: Added Context Types section to the library reference
1866 and attempted to bring other PEP 343 related documentation into
1867 line with the implementation and/or python-dev discussions.
1868
Tim Peters8dc73d22006-04-24 02:03:16 +00001869- Bug #1337990: clarified that ``doctest`` does not support examples
1870 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001873What's New in Python 2.5 alpha 1?
1874=================================
1875
Anthony Baxterebed3f62006-04-03 15:03:44 +00001876*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001877
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001878Core and builtins
1879-----------------
1880
Nick Coghlan43832302006-04-23 17:04:07 +00001881- PEP 338: -m command line switch now delegates to runpy.run_module
1882 allowing it to support modules in packages and zipfiles
1883
Martin v. Löwisc661b882006-04-20 04:54:23 +00001884- On Windows, .DLL is not an accepted file name extension for
1885 extension modules anymore; extensions are only found if they
1886 end in .PYD.
1887
Martin v. Löwisea62d252006-04-03 10:56:49 +00001888- Bug #1421664: sys.stderr.encoding is now set to the same value as
1889 sys.stdout.encoding.
1890
Neal Norwitz92e212f2006-04-03 04:48:37 +00001891- __import__ accepts keyword arguments.
1892
Georg Brandlccadf842006-03-31 18:54:53 +00001893- Patch #1460496: round() now accepts keyword arguments.
1894
Anthony Baxter262c00a2006-03-30 10:53:17 +00001895- Fixed bug #1459029 - unicode reprs were double-escaped.
1896
Hye-Shik Changd478f342006-03-23 12:32:36 +00001897- Patch #1396919: The system scope threads are reenabled on FreeBSD
1898 5.4 and later versions.
1899
Neal Norwitze98ccf62006-03-23 05:39:47 +00001900- Bug #1115379: Compiling a Unicode string with an encoding declaration
1901 now gives a SyntaxError.
1902
Georg Brandlabd1ff82006-03-18 07:59:59 +00001903- Previously, Python code had no easy way to access the contents of a
1904 cell object. Now, a ``cell_contents`` attribute has been added
1905 (closes patch #1170323).
1906
Tim Peterscf79aac2006-03-16 01:14:46 +00001907- Patch #1123430: Python's small-object allocator now returns an arena to
1908 the system ``free()`` when all memory within an arena becomes unused
1909 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1910 freed. Some applications will see a drop in virtual memory size now,
1911 especially long-running applications that, from time to time, temporarily
1912 use a large number of small objects. Note that when Python returns an
1913 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001914 platform C library will in turn return that memory to the operating system.
1915 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001916 appears to be effective at least on Microsoft C and gcc-based systems.
1917 Thanks to Evan Jones for hard work and patience.
1918
Georg Brandl533ff6f2006-03-08 18:09:27 +00001919- Patch #1434038: property() now uses the getter's docstring if there is
1920 no "doc" argument given. This makes it possible to legitimately use
1921 property() as a decorator to produce a read-only property.
1922
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001923- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1924 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1925 of requiring an int or long in slicing and a few other contexts, enabling
1926 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1927
Neal Norwitz995acdf2006-03-07 05:01:00 +00001928- Fixed various bugs reported by Coverity's Prevent tool.
1929
Brett Cannonbf364092006-03-01 04:25:17 +00001930- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1931 new exception base class, BaseException, which has a new message attribute.
1932 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1933 Raising a string exception now raises a DeprecationWarning.
1934
Thomas Woutersfb609f42006-02-28 16:37:25 +00001935- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1936 explicitly relative, using 'from .module import name' to mean 'from the same
1937 package as this module is in. Imports without dots still default to the
1938 old relative-then-absolute, unless 'from __future__ import
1939 absolute_import' is used.
1940
Brett Cannona7446e32006-02-27 23:39:10 +00001941- Properly check if 'warnings' raises an exception (usually when a filter set
1942 to "error" is triggered) when raising a warning for raising string
1943 exceptions.
1944
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001945- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001946 The name was removed from Include/code.h.
1947
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001948- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001949
Guido van Rossum1968ad32006-02-25 22:38:04 +00001950- Patch 1433928:
1951 - The copy module now "copies" function objects (as atomic objects).
1952 - dict.__getitem__ now looks for a __missing__ hook before raising
1953 KeyError.
1954
Tim Peters84ef21c2006-02-28 20:39:06 +00001955- PEP 343: with statement implemented. Needs ``from __future__ import
1956 with_statement``. Use of 'with' as a variable will generate a warning.
1957 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001958 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001959 The following objects have __context__ methods:
1960 - The built-in file type.
1961 - The thread.LockType type.
1962 - The following types defined by the threading module:
1963 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1964 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001965
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001966- Fix the encodings package codec search function to only search
1967 inside its own package. Fixes problem reported in patch #1433198.
1968
1969 Note: Codec packages should implement and register their own
1970 codec search function. PEP 100 has the details.
1971
Tim Peters9ea89d22006-06-04 03:26:02 +00001972- PEP 353: Using ``Py_ssize_t`` as the index type.
1973
1974- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1975 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1976 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1977 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1978 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001979
Neal Norwitzfc76d632006-01-10 06:03:13 +00001980- Patch #1400181, fix unicode string formatting to not use the locale.
1981 This is how string objects work. u'%f' could use , instead of .
1982 for the decimal point. Now both strings and unicode always use periods.
1983
Neal Norwitz671b9e32006-01-09 07:07:12 +00001984- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1985 configure would break checking curses.h.
1986
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001987- Bug #959576: The pwd module is now builtin. This allows Python to be
1988 built on UNIX platforms without $HOME set.
1989
Neal Norwitzc10978f2005-12-19 06:07:16 +00001990- Bug #1072182, fix some potential problems if characters are signed.
1991
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001992- Bug #889500, fix line number on SyntaxWarning for global declarations.
1993
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001994- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1995
Neal Norwitze7214a12005-12-18 05:03:17 +00001996- Support for converting hex strings to floats no longer works.
1997 This was not portable. float('0x3') now raises a ValueError.
1998
Barry Warsaw2a38a862005-12-18 01:27:35 +00001999- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002000 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002001 is now displayed in interactive prompt banner.
2002
Georg Brandlfa166682005-12-17 21:45:17 +00002003- Implementation of PEP 341 - Unification of try/except and try/finally.
2004 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002005 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002006
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002007- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2008 now encodes backslash correctly.
2009
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002010- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2011
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002012- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002013 and long longs.
2014
Neal Norwitz67715f02005-11-09 06:59:35 +00002015- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002016 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002017 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002018
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002019- Replaced most Unicode charmap codecs with new ones using the
2020 new Unicode translate string feature in the builtin charmap
2021 codec; the codecs were created from the mapping tables available
2022 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2023 encodings now include a mapping for the Apple logo)
2024
Tim Peterse3547fd2005-12-16 23:13:57 +00002025- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002026
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002027- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002028
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002029- A new AST parser implementation was completed. The abstract
2030 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002031 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002032
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002033- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002034 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2035
Neal Norwitz708e51a2005-10-03 04:48:15 +00002036- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2037
Neal Norwitz11bd1192005-10-03 00:54:56 +00002038- SF Bug #887946: fix segfault when redirecting stdin from a directory.

2042
2043- SF bug #772896: unknown encoding results in MemoryError.
2044
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002045- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002046 supported a __len__() method which evaluated to False when the iterator
2047 was empty.
2048
Guido van Rossum630db602005-09-20 18:49:54 +00002049- On 64-bit platforms, when __len__() returns a value that cannot be
2050 represented as a C int, raise OverflowError.

Skip Montanarof8948ca2005-09-19 03:54:46 +00002052- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002053 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002054
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002055- SF bug #893549: parsing keyword arguments was broken with a few format
2056 codes.
2057
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002058- Changes donated by Elemental Security to make it work on AIX 5.3
2059 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2060 bug #105470: test_pwd fails on 64bit system (Opteron).
2061
Guido van Rossum539c6622005-09-14 17:49:54 +00002062- Changes donated by Elemental Security to make it work on HP-UX 11 on
2063 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2064
Georg Brandl4550b8d2005-08-26 06:43:52 +00002065- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002066 (fixes bug #1119418).
2067
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002068- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2069
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002070- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2071 exceptions that cause a function to exit.
2072
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002073- The implementation of set() and frozenset() was revised to use its
2074 own internal data structure. Memory consumption is reduced by 1/3
2075 and there are modest speed-ups as well. The API is unchanged.
2076
Tim Petersde7990b2005-07-17 23:45:23 +00002077- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2078
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002079- SF bug #1229429: PyObject_CallMethod failed to decrement some
2080 reference counts in some error exit cases.
2081
Tim Petersecc6e6a2005-07-10 22:30:55 +00002082- SF bug #1185883: Python's small-object memory allocator took over
2083 a block managed by the platform C library whenever a realloc specified
2084 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002085 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002086 portable way to copy data from the C-managed block into Python's
2087 small-object space without risking a memory fault. Python's small-object
2088 realloc now leaves such blocks under the control of the platform C
2089 realloc.
2090
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002091- SF bug #1232517: An overflow error was not detected properly when
2092 attempting to convert a large float to an int in os.utime().
2093
Raymond Hettinger3296e692005-06-29 23:29:56 +00002094- SF bug #1224347: hex longs now print with lowercase letters just
2095 like their int counterparts.
2096
Michael W. Hudson188d4362005-06-20 16:52:57 +00002097- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2098 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2099 interpreter states; back out that fix and do a better job (see
2100 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2101 for a longer write-up of the problem).
2102
Michael W. Hudsondf888462005-06-03 14:41:55 +00002103- SF patch #1180995: marshal now uses a binary format by default when
2104 serializing floats.
2105
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002106- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2107 the routines that promise to produce IEEE 754 binary representations
2108 of floats now simply copy bytes around.
2109
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002110- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2111 278.
2112
Brett Cannonc3647ac2005-04-26 03:45:26 +00002113- patch #1109424: int, long, float, complex, and unicode now check for the
2114 proper magic slot for type conversions when subclassed. Previously the
2115 magic slot was ignored during conversion. Semantics now match the way
2116 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002117 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002118 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002119 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002120
Barry Warsawc8d907c2005-04-19 23:43:40 +00002121- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2122 NULL, now raise an AttributeError when attempting to set or delete the
2123 attribute. Previously a TypeError was raised, but this was inconsistent
2124 with the equivalent pure-Python implementation.
2125
Michael W. Hudson774479c2005-04-18 08:46:17 +00002126- It is now safe to call PyGILState_Release() before
2127 PyEval_InitThreads() (note that if there is reason to believe there
2128 are multiple threads around you still must call PyEval_InitThreads()
2129 before using the Python API; this fix is for extension modules that
2130 have no way of knowing if Python is multi-threaded yet).
2131
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002132- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2133 disabled caused a crash.
2134
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002135- Bug #1165306: instancemethod_new allowed the creation of a method
2136 with im_class == im_self == NULL, which caused a crash when called.
2137
Tim Petersecc6e6a2005-07-10 22:30:55 +00002138- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002139 fixes the crash seen in bug #1165761
2140
Raymond Hettinger96229b12005-03-11 06:49:40 +00002141- Added two new builtins, any() and all().
2142
Brett Cannon409d8f22005-03-05 06:47:57 +00002143- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002144 (e.g., ``class C(): pass`` is no longer a syntax error).
2145 Patch #1176012 added support to the 'parser' module and 'compiler' package
2146 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002147
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002148- Patch #1115086: Support PY_LONGLONG in structmember.
2149
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002150- Bug #1155938: new style classes did not check that __init__() was
2151 returning None.
2152
Tim Petersecc6e6a2005-07-10 22:30:55 +00002153- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002154 ('\') with a specific error message.
2155
Martin v. Löwisff232d72005-03-03 09:24:38 +00002156- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2157
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002158- Bug #1124295: the __name__ attribute of file objects was
2159 inadvertently made inaccessible in restricted mode.
2160
Tim Petersecc6e6a2005-07-10 22:30:55 +00002161- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002162 an ferror() call.
2163
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002164- min() and max() now support key= arguments with the same meaning as in
2165 list.sort().
2166
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002167- The peephole optimizer now performs simple constant folding in expressions:
2168 (2+3) --> (5).
2169
Raymond Hettingera422c342005-01-11 03:03:27 +00002170- set and frozenset objects can now be marshalled. SF #1098985.
2171
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002172- Bug #1077106: Poor argument checking could cause memory corruption
2173 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002174
Jeremy Hyltonab630502005-02-04 18:44:06 +00002175- The parser did not complain about future statements in illegal
2176 positions. It once again reports a syntax error if a future
2177 statement occurs after anything other than a doc string.
2178
Neil Schemenauercf52c072005-08-12 17:34:58 +00002179- Change the %s format specifier for str objects so that it returns a
2180 unicode instance if the argument is not an instance of basestring and
2181 calling __str__ on the argument returns a unicode instance.
2182
Tim Petersf4e69282006-02-27 17:15:31 +00002183- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2184 current thread state when the auto-GIL-state machinery knows about
2185 it (since the thread state is being deleted, continuing to remember it
2186 can't help, but can hurt if another thread happens to get created with
2187 the same thread id).

2206
2207- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2208
2209- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002210 is deprecated. The undocumented re.engine variable no longer exists.
2211

2213 SS2 (single-shift 2) escape sequences correctly.
2214
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002215- The unicodedata module was updated to the 4.1 version of the Unicode
2216 database. The 3.2 version is still available as unicodedata.db_3_2_0
2217 for applications that require this specific version (such as IDNA).
2218
Neal Norwitzb62c4332006-03-04 18:35:47 +00002219- The timing module is no longer built by default. It was deprecated
2220 in PEP 4 in Python 2.0 or earlier.
2221
Guido van Rossum1968ad32006-02-25 22:38:04 +00002222- Patch 1433928: Added a new type, defaultdict, to the collections module.
2223 This uses the new __missing__ hook behavior added to dict (see above).
2224
Georg Brandldbd83392006-02-20 09:42:33 +00002225- Bug #854823: socketmodule now builds on Sun platforms even when
2226 INET_ADDRSTRLEN is not defined.
2227
Georg Brandlf4f44152006-02-18 22:29:33 +00002228- Patch #1393157: os.startfile() now has an optional argument to specify
2229 a "command verb" to invoke on the file.
2230
Neal Norwitz082b2df2006-02-07 07:04:46 +00002231- Bug #876637, prevent stack corruption when socket descriptor

2233
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002234- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2235 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.

2239 than the system default domain.
2240
Martin v. Löwis14694662006-02-03 12:54:16 +00002241- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2242 are reported, the limit on path name lengths is removed, and stat reports
2243 WindowsError now (instead of OSError).
2244
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002245- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2320 the request code argument, which results in more C-like behaviour
2321 for large or negative values.
2322
Tim Petersecc6e6a2005-07-10 22:30:55 +00002323- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2332 available on the platform.
2333
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002334- Bug #1166660: The readline module could segfault if hook functions
2335 were set in a different thread than that which called readline.
2336
Raymond Hettinger4aec61e2005-03-18 21:20:23 +00002337- collections.deque objects now support a remove() method.
2338
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002339- operator.itemgetter() and operator.attrgetter() now support retrieving

2365
Raymond Hettingerb2594052004-12-05 09:25:51 +00002366- itertools.islice() now accepts None for the start and step arguments.
2367 This allows islice() to work more readily with slices:
2368 islice(s.start, s.stop, s.step)
2369
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002370- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002379- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2380 been renamed to have only a single underscore prefix. This was done to
2381 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002382
Nick Coghlan43832302006-04-23 17:04:07 +00002383- PEP 338: new module runpy defines a run_module function to support
2384 executing modules which provide access to source code or a code object
2385 via the PEP 302 import mechanisms.
2386
Anthony Baxter93f5b932006-04-03 08:05:07 +00002387- The email module's parsedate_tz function now sets the daylight savings
2388 flag to -1 (unknown) since it can't tell from the date whether it should

2395 in attribute values.
2396
Anthony Baxterc51ee692006-04-01 00:57:31 +00002397- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002398 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002399 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002400 module will not be built.
2401
Tim Petersc17976e2006-04-01 00:26:53 +00002402- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2403 aren't officially supported here, and trying to use them will probably
2404 raise an exception some day. But dicts have been allowed, and "mostly
2405 worked", so support for them won't go away without warning.
2406
Georg Brandl338ef7d2006-03-31 18:42:16 +00002407- Bug #1445068: getpass.getpass() can now be given an explicit stream
2408 argument to specify where to write the prompt.
2409
Georg Brandl22ec80b2006-03-31 18:25:44 +00002410- Patch #1462313, bug #1443328: the pickle modules now can handle classes
2411 that have __private names in their __slots__.
2412

2417
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002418- Queue.Queue objects now support .task_done() and .join() methods
2419 to make it easier to monitor when daemon threads have completed
2420 processing all enqueued tasks. Patch #1455676.
2421
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002422- popen2.Popen objects now preserve the command in a .cmd attribute.

2425
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002426- email 4.0 package now integrated. This is largely the same as the email 3.0
2427 package that was included in Python 2.3, except that PEP 8 module names are
2428 now used (e.g. mail.message instead of email.Message). The MIME classes
2429 have been moved to a subpackage (e.g. email.mime.text instead of
2430 email.MIMEText). The old names are still supported for now. Several
2431 deprecated Message methods have been removed and lots of bugs have been
2432 fixed. More details can be found in the email package documentation.
2433
Walter Dörwald40108c92006-03-27 08:15:44 +00002434- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2435 (a subclass of tuple) that provides incremental decoders and encoders
2436 (a way to use stateful codecs without the stream API). Python functions
2437 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2438 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2439 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002440
Walter Dörwald067db482006-03-15 22:17:27 +00002441- Patch #1359365: Calling next() on a closed StringIO.String object raises
2442 a ValueError instead of a StopIteration now (like file and cString.String do).
2443 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2444 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002445
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002446- A regrtest option -w was added to re-run failed tests in verbose mode.

2456
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002457- PEP 343: new module contextlib.py defines decorator @contextmanager
2458 and helpful context managers nested() and closing().
2459

2464
Georg Brandlc98eeed2006-02-19 14:57:47 +00002465- Patch #1215184: FileInput now can be given an opening hook which can

Tim Peterse3547fd2005-12-16 23:13:57 +00002518 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2519 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2520 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2521 Ronald L. Rivest offered this advice for Python:
2522
2523 "The consensus of researchers in this area (at least as
2524 expressed at the NIST Hash Function Workshop 10/31/05),
2525 is that SHA-256 is a good choice for the time being, but
2526 that research should continue, and other alternatives may
2527 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002528
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002529- Added a subset of Fredrik Lundh's ElementTree package. Available

2582 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002583 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002584

Guido van Rossum755149f2005-07-27 00:00:44 +00002592- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
2593 __hasattr__ and __delattr__ methods on class Tk that were breaking
2594 Tkdnd.
2595
Georg Brandl5dbda752005-07-17 20:27:41 +00002596- Bug #1015140: disambiguated the term "article id" in nntplib docs and
2597 docstrings to either "article number" or "message id".
2598
Georg Brandla4a8b822005-07-15 09:13:21 +00002599- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2600 parameter, but uses the usual "kwargs=None".
2601
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002602- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002603 Patch #1209527 (Contributed by Connelly).
2604
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002605- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2606 to W3C name (404 -> 'Not Found'). RFE #1216944.
2607
Georg Brandl9e43acf2005-07-04 17:16:07 +00002608- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2609 as this can cause problems with apps closing all file descriptors.
2610
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002611- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002612 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002613
Georg Brandl2f210b62005-06-26 22:09:06 +00002614- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2615
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002616- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2617 error messages.
2618
Georg Brandl379f99d2005-06-26 21:09:38 +00002619- Bug #1108948: Cookie.py produced invalid JavaScript code.
2620
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002621- The tokenize module now detects and reports indentation errors.
2622 Bug #1224621.
2623
Raymond Hettinger68c04532005-06-10 11:05:19 +00002624- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002625 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002626 the generate_tokens() function now accepts a callable argument that
2627 terminates by raising StopIteration.
2628
Georg Brandl9166e1a2005-06-04 09:20:03 +00002629- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2630
Georg Brandl268e61c2005-06-03 14:28:50 +00002631- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2632 component of the path.
2633
Skip Montanaro174dd222005-05-14 20:54:16 +00002634- Patch #1120353: The xmlrpclib module provides better, more transparent,
2635 support for datetime.{datetime,date,time} objects. With use_datetime set
2636 to True, applications shouldn't have to fiddle with the DateTime wrapper
2637 class at all.
2638
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002639- distutils.commands.upload was added to support uploading distribution
2640 files to PyPI.
2641
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002642- distutils.commands.register now encodes the data as UTF-8 before posting
2643 them to PyPI.
2644
Raymond Hettinger267b8682005-03-27 10:47:39 +00002645- decimal operator and comparison methods now return NotImplemented
2646 instead of raising a TypeError when interacting with other types. This
2647 allows other classes to implement __radd__ style methods and have them
2648 work as expected.
2649
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002650- Bug #1163325: Decimal infinities failed to hash. Attempting to
2651 hash a NaN raised an InvalidOperation instead of a TypeError.
2652
Tim Petersecc6e6a2005-07-10 22:30:55 +00002653- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002654 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2655

2685
Raymond Hettingerbab41432005-02-05 01:31:19 +00002686- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2687
Guido van Rossumd0641422005-02-03 15:01:24 +00002688- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2689 disables recursive traversal through instance attributes, which can
2690 be exploited in various ways.
2691
Tim Peterse3547fd2005-12-16 23:13:57 +00002692- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002693 flags on the HTTP listening socket.
2694
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002695- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2696 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2697
Fred Drakefbdeaad2006-07-29 16:56:15 +00002698- Patches #893642, #1039083: add allow_none, encoding arguments to
2699 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002700
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002701- Bug #1110478: Revert os.environ.update to do putenv again.
2702
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002703- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2704
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002705- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2706
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002707- Enhancements to the csv module:
2708
2709 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002710 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002711 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002712 + Dialect parameter parsing has been re-implemented to improve error
2713 reporting.
2714 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2715 dictates.
2716 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002717 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002718 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002719 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2720 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002721 + reader now allows \r characters to be quoted (previously it only allowed
2722 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002723 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002724 + Dialect classes passed to the module are no longer instantiated by
2725 the module before being parsed (the former validation scheme required
2726 this, but the mechanism was unreliable).
2727 + The dialect registry now contains instances of the internal
2728 C-coded dialect type, rather than references to python objects.
2729 + the internal c-coded dialect type is now immutable.
2730 + register_dialect now accepts the same keyword dialect specifications
2731 as the reader and writer, allowing the user to register dialects
2732 without first creating a dialect class.
2733 + a configurable limit to the size of parsed fields has been added -
2734 previously, an unmatched quote character could result in the entire
2735 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002736 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002737 the parser field size limit (returning the former limit). The initial
2738 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002739 + A line_num attribute has been added to the reader object, which tracks
2740 the number of lines read from the source iterator. This is not
2741 the same as the number of records returned, as records can span
2742 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002743 + reader and writer objects were not being registered with the cyclic-GC.
2744 This has been fixed.
2745
Brett Cannone6539c42005-01-08 02:43:53 +00002746- _DummyThread objects in the threading module now delete self.__block that is
2747 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2748 lock primitives tend to be limited in number and thus should not be wasted on
2749 a _DummyThread object. Fixes bug #1089632.
2750
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002751- The imghdr module now detects Exif files.
2752
Raymond Hettinger6065d322004-12-20 23:51:53 +00002753- StringIO.truncate() now correctly adjusts the size attribute.
2754 (Bug #951915).
2755
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002756- locale.py now uses an updated locale alias table (built using
2757 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2758 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002759 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002760
Raymond Hettinger3557f422004-12-07 12:02:02 +00002761- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2762
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002763- the pickle module no longer accepts the deprecated None option in the
2764 args tuple returned by __reduce__().
2765
Brett Cannon84667c02004-12-07 03:25:18 +00002766- optparse now optionally imports gettext. This allows its use in setup.py.
2767
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002768- the pickle module no longer uses the deprecated bin parameter.
2769
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002770- the shelve module no longer uses the deprecated binary parameter.
2771
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002772- the pstats module no longer uses the deprecated ignore() method.
2773
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002774- the filecmp module no longer uses the deprecated use_statcache argument.
2775
Raymond Hettinger664347b2004-12-04 21:21:53 +00002776- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2777 extended or overridden by subclasses. Formerly, the subclassed method would
2778 be ignored by the rest of the module. (Bug #1078905).
2779
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002780- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002781 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002782
Walter Dörwald36733692004-12-22 12:50:50 +00002783- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2784 once when a size argument is given. This prevents a buffer overflow in the
2785 tokenizer with very long source lines.
2786
Barry Warsaw538561e2006-01-01 21:48:54 +00002787- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2788 immediately after creating the object, without any intervening
2789 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002790
Skip Montanaro05885812005-01-16 20:48:27 +00002791- The reconvert.quote function can now emit triple-quoted strings. The
2792 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002793
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002794- ``UserString.MutableString`` now supports negative indices in
2795 ``__setitem__`` and ``__delitem__``
2796
Greg Ward40407942005-03-05 02:53:17 +00002797- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2798 correctly.
2799
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002800- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2801 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2802 character even if the user has passed a size parameter to get a proper
2803 line ending. Remove the special handling of a "\r\n" that has been split
2804 between two lines.
2805
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002806- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2807 about illegal code points. The codec now supports PEP 293 style error
2808 handlers.
2809
Walter Dörwald78a78b02005-09-01 12:04:29 +00002810- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002811 from the input stream, so that the output is a byte string in the correct
2812 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002813
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002814- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2815 considering it exactly like a '*'.
2816
Walter Dörwald007f8df2005-10-09 19:42:27 +00002817- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2818 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002819
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002820- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2821
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002822- Patch #1413711: Certain patterns of differences were making difflib
2823 touch the recursion limit.
2824
Walter Dörwald58917a62006-03-31 15:26:22 +00002825- Bug #947906: An object oriented interface has been added to the calendar
2826 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002827 called as a script (e.g. via ``python -mcalendar``). Localized month and
2828 weekday names can be ouput (even if an exotic encoding is used) using
2829 special classes that use unicode.

Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002841- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2842
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002843- Patch #881820: look for openpty and forkpty also in libbsd.
2844
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002845- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2846 The zlib module is now builtin on Windows.
2847
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002848- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2849
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002850- Bug #1189330: configure did not correctly determine the necessary
2851 value of LINKCC if python was built with GCC 4.0.
2852
Trent Mick8321b422005-07-26 02:29:21 +00002853- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2854 vulnerability in zlib 1.2.1 and 1.2.2.
2855
Brett Cannon08cd5982005-04-24 22:26:38 +00002856- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2857 flags that change binary compatibility. Changes were also made to
2858 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002859 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002860
Bob Ippolitoed233462005-03-29 13:47:59 +00002861- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2862 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2863 no longer exists). This configure patch makes things right.
2864
Martin v. Löwise2713be2005-03-08 15:03:08 +00002865- Bug #1158607: Build with --disable-unicode again.
2866
Brett Cannon46d96232005-02-16 00:07:19 +00002867- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2868 defined. Discovered as a result of not being able to build on OS X.
2869
Brett Cannon516592f2004-12-07 00:42:59 +00002870- setup.py now uses the directories specified in LDFLAGS using the -L option
2871 and in CPPFLAGS using the -I option for adding library and include
2872 directories, respectively, for compiling extension modules against. This has
2873 led to the core being compiled using the values in CPPFLAGS. It also removes
2874 the need for the special-casing of both DarwinPorts and Fink for darwin since
2875 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2876 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2877 Fink, ``-I/opt/local/include`` for DarwinPorts).
2878
Brett Cannon43802422005-02-10 20:48:03 +00002879- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2880 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2881 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2882 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002884C API
2885-----
2886
Tim Petersc9d78aa2006-03-26 23:27:58 +00002887- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2888 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2889 is obtained via the ``PyObject_`` family, it must be released via the
2890 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2891 always been officially true, but when Python's small-object allocator was
2892 introduced, an attempt was made to cater to a few extension modules
2893 discovered at the time that obtained memory via ``PyObject_New`` but
2894 released it via ``PyMem_DEL``. It's years later, and if such code still
2895 exists it will fail now (probably with segfaults, but calling wrong
2896 low-level memory management functions can yield many symptoms).
2897
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002898- Added a C API for set and frozenset objects.
2899

2901
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002902- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2903 mapping argument now. This string is used as a mapping table. Byte values
2904 greater than the length of the string and 0xFFFE are treated as undefined
2905 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002912
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002913- Patch #1276356: New resource "urlfetch" is implemented. This enables
2914 even impatient people to run tests that require remote files.
