Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000603- The return tuple from str.rpartition(sep) is (tail, sep, head) where
604 head is the original string if sep was not found.
605
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000606- Bug #1520864: unpacking singleton tuples in list comprehensions and
607 generator expressions (x for x, in ... ) works again. Fixing this problem
608 required changing the .pyc magic number. This means that .pyc files
609 generated before 2.5c2 will be regenerated.

721Core and builtins
722-----------------
723
Neal Norwitz24b6f202006-09-05 04:43:56 +0000724- Fix infinite recursion when subclassing long and overriding __hash__.
725
726- Fix concatenation (+=) of long strings.
727
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000728- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000729 compared equal or unequal to a string and a UnicodeDecodeError
730 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000731
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000732 Instead, the equal (==) and unequal (!=) comparison operators will
733 now issue a UnicodeWarning and interpret the two objects as
734 unequal. The UnicodeWarning can be filtered as desired using
735 the warning framework, e.g. silenced completely, turned into an
736 exception, logged, etc.
737
738 Note that compare operators other than equal and unequal will still
739 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000740
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000741- Fix segfault when doing string formatting on subclasses of long.
742
743- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
744 with new-style classes.
745
746- Fix bug related to __len__ functions returning negative values with
747 classic classes.
748
749- Patch #1538606, Fix __index__() clipping. There were some problems
750 discovered with the API and how integers that didn't fit into Py_ssize_t
751 were handled. This patch attempts to provide enough alternatives
752 to effectively use __index__.
753
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000754- Bug #1536021: __hash__ may now return long int; the final hash
755 value is obtained by invoking hash on the long int.
756
Thomas Hellerab1049c2006-08-08 17:37:00 +0000757- Bug #1536786: buffer comparison could emit a RuntimeWarning.

760 sys.stdin is closed.
761
Thomas Heller74d36f02006-08-04 18:17:40 +0000762- On Windows, the PyErr_Warn function is now exported from
763 the Python dll again.
764
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000765- Bug #1191458: tracing over for loops now produces a line event
766 on each iteration. Fixing this problem required changing the .pyc
767 magic number. This means that .pyc files generated before 2.5c1
768 will be regenerated.
769
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000770- Bug #1333982: string/number constants were inappropriately stored
771 in the byte code and co_consts even if they were not used, ie
772 immediately popped off the stack.
773
Georg Brandle9462c72006-08-04 18:03:37 +0000774- Fixed a reference-counting problem in property().

778-------
779
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000780- Fix a bug in the ``compiler`` package that caused invalid code to be
781 generated for generator expressions.
782
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000783- The distutils version has been changed to 2.5.0. The change to
784 keep it programmatically in sync with the Python version running
785 the code (introduced in 2.5b3) has been reverted. It will continue
786 to be maintained manually as static string literal.
787
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000788- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000789 and this cannot be converted to the required C type, an exception is
790 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000791 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000792
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000793- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000794 an exception.
795
Tim Peterscbdd3502006-09-05 01:47:53 +0000796- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000797 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000798 workarounds for clocks with low resolution, to stop the code yielding
799 duplicate UUIDs.
800
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000801- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
802 before raising SystemExit, allowing IDLE to honor quit() and exit().
803
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000804- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
805
Georg Brandl7a1af772006-08-14 21:55:28 +0000806- Patch #1536071: trace.py should now find the full module name of a
807 file correctly even on Windows.

Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000809- logging's atexit hook now runs even if the rest of the module has
810 already been cleaned up.

836 function calls. The ctypes version number was changed to 1.0.1.
837
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000838- Bug #1530559, struct.pack raises TypeError where it used to convert.
839 Passing float arguments to struct.pack when integers are expected
840 now triggers a DeprecationWarning.

895
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000896- Bug #1515471: string.replace() accepts character buffers again.

900 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().

Neal Norwitz0d62a062006-07-30 06:53:31 +0000902- Patch #1531113: Fix augmented assignment with yield expressions.
903 Also fix a SystemError when trying to assign to yield expressions.
904
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000905- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
906 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
907 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
908 excessive filesystem operations during imports.
909
Tim Petersbc24eee2006-07-27 01:14:53 +0000910- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
911 operations on signed longs that are formally undefined by C.
912 Unfortunately, at least one compiler now cares about that, so complicated
913 the code to make that compiler happy again.
914
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000915- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
916
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000917- Patch #1232023: Stop including current directory in search
918 path on Windows.
919
Neal Norwitze1fdb322006-07-21 05:32:28 +0000920- Fix some potential crashes found with failmalloc.
921
Neal Norwitze7563102006-07-17 01:00:16 +0000922- Fix warnings reported by Klocwork's static analysis tool.
923
Neal Norwitz84be93b2006-07-16 01:50:38 +0000924- Bug #1512814, Fix incorrect lineno's when code within a function
925 had more than 255 blank lines.
926
Georg Brandl9dceedb2006-07-12 15:31:17 +0000927- Patch #1521179: Python now accepts the standard options ``--help`` and
928 ``--version`` as well as ``/?`` on Windows.
929
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000930- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000931 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000932 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000933
Tim Peters112aad32006-07-19 00:03:19 +0000934- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000935 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000936 new ``sys._current_frames()`` returns a dictionary with one entry,
937 mapping the faux "thread id" 0 to the current frame.
938
Ronald Oussoren3075e162006-07-25 20:28:55 +0000939- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

943-------
944
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000945- Correction of patch #1455898: In the mbcs decoder, set final=False
946 for stream decoder, but final=True for the decode function.
947
Georg Brandl07fec3a2006-08-01 18:49:24 +0000948- os.urandom no longer masks unrelated exceptions like SystemExit or
949 KeyboardInterrupt.
950
Tim Peters4643c2f2006-08-10 22:45:34 +0000951- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000952 shutil.copytree on Windows
953
Georg Brandle34ac7c2006-07-30 11:07:23 +0000954- Bug #1002398: The documentation for os.path.sameopenfile now correctly
955 refers to file descriptors, not file objects.
956
Tim Peterscbdd3502006-09-05 01:47:53 +0000957- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000958 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000959 #1513611, and probably others.
960
Georg Brandledd9b0d2006-07-29 09:33:26 +0000961- Bug #1441397: The compiler module now recognizes module and function
962 docstrings correctly as it did in Python 2.4.
963
Tim Peters6f681472006-07-27 23:44:37 +0000964- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
965 lost that tests are sorted by name before being run. This rarely
966 matters for well-written tests, but can create baffling symptoms if
967 side effects from one test to the next affect outcomes. ``DocTestFinder``
968 has been changed to sort the list of tests it returns.
969
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000970- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000971 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000972
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000973- Bug #978833: Really close underlying socket in _socketobject.close.
974
Georg Brandldb232dc2006-08-20 13:15:43 +0000975- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
976 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000977
Georg Brandlcf0c1722006-07-26 07:23:32 +0000978- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
979 to recursive calls and call it with the failing package name.
980
Martin v. Löwis0b483032006-07-25 09:53:12 +0000981- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
982
Georg Brandlc13c34c2006-07-24 14:09:56 +0000983- Patch #1515343: Fix printing of deprecated string exceptions with a
984 value in the traceback module.
985
Greg Ward48fae7a2006-07-23 16:05:51 +0000986- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
987
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000988- Patch #1524429: Use repr() instead of backticks in Tkinter again.
989
Brett Cannoncaebe222006-07-18 04:41:36 +0000990- Bug #1520914: Change time.strftime() to accept a zero for any position in its
991 argument tuple. For arguments where zero is illegal, the value is forced to
992 the minimum value that is correct. This is to support an undocumented but
993 common way people used to fill in inconsequential information in the time
994 tuple pre-2.4.
995
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000996- Patch #1220874: Update the binhex module for Mach-O.
997
Barry Warsawb110bad2006-07-21 14:51:07 +0000998- The email package has improved RFC 2231 support, specifically for
999 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1000 (name*0=<blah>) parameter continuations. This may change the types of
1001 values returned from email.message.Message.get_param() and friends.
1002 Specifically in some cases where non-encoded continuations were used,
1003 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1004 will just return the string (since non-encoded continuations don't have
1005 charset and language parts).
1006
1007 Also, whereas % values were decoded in all parameter continuations, they are
1008 now only decoded in encoded parameter parts.
1009
Ronald Oussoren3075e162006-07-25 20:28:55 +00001010- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1011
1012- Bug #1517996: IDLE now longer shows the default Tk menu when a
1013 path browser, class browser or debugger is the frontmost window on MacOS X
1014
Barry Warsaw00decd72006-07-27 23:43:15 +00001015- Patch #1520294: Support for getset and member descriptors in types.py,
1016 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1017 of an object against these built-in types and more importantly, for getting
1018 their docstrings printed in the interactive interpreter's help() function.

1022-----------------
1023
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001024- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1025 a socket operation on a socket with a timeout, the exception will be
1026 caught correctly. Previously, the exception was not caught.
1027
Thomas Heller1393d6a2006-07-28 21:43:20 +00001028- Patch #1529514: The _ctypes extension is now compiled on more
1029 openbsd target platforms.
1030
Tim Peters9cab5932006-07-28 00:30:00 +00001031- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1032 a memory leak, affecting pickles and deep copies.
1033
Tim Petersbc24eee2006-07-27 01:14:53 +00001034- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001035 Paul Eggert.
1036
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001037- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1038
Thomas Hellerce049a02006-07-14 17:51:14 +00001039- Patch #1521817: Index range checking on ctypes arrays containing
1040 exactly one element enabled again. This allows iterating over these
1041 arrays, without the need to check the array size before.
1042
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001043- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001044 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001045 /dev/null in certain cases; this is now fixed.
1046
Thomas Heller47d7a062006-07-12 08:43:47 +00001047- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1048 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001049
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001050- Because of a misspelled preprocessor symbol, ctypes was always
1051 compiled without thread support; this is now fixed.
1052
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001053- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1054 methods now allow their database parameter to be None as the
1055 sleepycat API allows.
1056
Matt Flemingec926502006-07-28 11:27:27 +00001057- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1058 bluetooth API compared with Linux and FreeBSD.
1059
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001060Tests
1061-----
1062
1063- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1064 how long the test file should take to play. Now accepts taking 2.93 secs
1065 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1066
Georg Brandl4793aa32006-07-28 18:31:39 +00001067- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1068 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1069 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001076Mac
1077---
1078
1079- PythonLauncher now works correctly when the path to the script contains
1080 characters that are treated specially by the shell (such as quotes).
1081
1082- Bug #1527397: PythonLauncher now launches scripts with the working directory
1083 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001084 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001085 expect.

1094-----------------
1095
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001096- Bug #1441486: The literal representation of -(sys.maxint - 1)
1097 again evaluates to a int object, not a long.
1098
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001099- Bug #1501934: The scope of global variables that are locally assigned
1100 using augmented assignment is now correctly determined.
1101
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001102- Bug #927248: Recursive method-wrapper objects can now safely
1103 be released.
1104
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001105- Bug #1417699: Reject locale-specific decimal point in float()
1106 and atof().
1107
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001108- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1109 omit a default "error" argument for NULL pointer. This allows
1110 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001111
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001112- Bug #1519018: 'as' is now validated properly in import statements.
1113
Neal Norwitz28746ab2006-07-09 22:14:42 +00001114- On 64 bit systems, int literals that use less than 64 bits are
1115 now ints rather than longs.
1116
Neal Norwitzed657552006-07-10 00:04:44 +00001117- Bug #1512814, Fix incorrect lineno's when code at module scope
1118 started after line 256.
1119
Tim Peters32a83612006-07-10 21:08:24 +00001120- New function ``sys._current_frames()`` returns a dict mapping thread
1121 id to topmost thread stack frame. This is for expert use, and is
1122 especially useful for debugging application deadlocks. The functionality
1123 was previously available in Fazal Majid's ``threadframe`` extension
1124 module, but it wasn't possible to do this in a wholly threadsafe way from
1125 an extension.

1131 VS 2003.
1132
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001133- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1134
Tim Peters32a83612006-07-10 21:08:24 +00001135- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001136 environment variable to be set in order to the SDK environment
1137 for finding the compiler, include files, etc.

1142
Thomas Woutersadd19112006-07-05 11:03:49 +00001143- string.Template() now correctly handles tuple-values. Previously,
1144 multi-value tuples would raise an exception and single-value tuples would
1145 be treated as the value they contain, instead.
1146
Martin v. Löwisede77f52006-07-03 13:01:35 +00001147- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1148 even if some data are received.
1149
Martin v. Löwis45482392006-07-03 12:28:58 +00001150- Bug #1267547: Put proper recursive setup.py call into the
1151 spec file generated by bdist_rpm.
1152
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001153- Bug #1514693: Update turtle's heading when switching between
1154 degrees and radians.
1155
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001156- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001157 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001158
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001159- Bug #1514703: Only setup canvas window in turtle when the canvas
1160 is created.
1161
Martin v. Löwis7596e832006-07-01 15:33:37 +00001162- Bug #1513223: .close() of a _socketobj now releases the underlying
1163 socket again, which then gets closed as it becomes unreferenced.
1164
Fred Drake10497c82006-06-29 02:57:48 +00001165- Bug #1504333: Make sgmllib support angle brackets in quoted
1166 attribute values.
1167
1168- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1169 sgmllib ('[' and ']' were not accepted).
1170
Georg Brandl1be63af2006-06-28 20:23:25 +00001171- Fix a bug in the turtle module's end_fill function.
1172
Brett Cannon53ab5b72006-06-22 16:49:14 +00001173- Bug #1510580: The 'warnings' module improperly required that a Warning
1174 category be either a types.ClassType and a subclass of Warning. The proper
1175 check is just that it is a subclass with Warning as the documentation states.
1176
Georg Brandlad29e632006-06-21 17:45:17 +00001177- The compiler module now correctly compiles the new try-except-finally
1178 statement (bug #1509132).
1179
Neal Norwitz60373cd2006-06-22 06:30:50 +00001180- The wsgiref package is now installed properly on Unix.
1181
Vinay Sajip28e57612006-07-01 10:45:20 +00001182- A bug was fixed in logging.config.fileConfig() which caused a crash on
1183 shutdown when fileConfig() was called multiple times.

Gerhard Häring762fbd32006-07-02 17:48:30 +00001185- The sqlite3 module did cut off data from the SQLite database at the first
1186 null character before sending it to a custom converter. This has been fixed
1187 now.

1190-----------------
1191
Tim Peters112aad32006-07-19 00:03:19 +00001192- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1193 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1194 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001195
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001196- Assigning None to pointer type fields in ctypes structures possible
1197 overwrote the wrong fields, this is fixed now.
1198
1199- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1200 on non-Windows platforms.
1201
1202- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1203 integer or long, without range checking.
1204
1205- Patch #1517790: It is now possible to use custom objects in the ctypes
1206 foreign function argtypes sequence as long as they provide a from_param
1207 method, no longer is it required that the object is a ctypes type.
1208
1209- The '_ctypes' extension module now works when Python is configured
1210 with the --without-threads option.
1211
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001212- Bug #1513646: os.access on Windows now correctly determines write
1213 access, again.
1214
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001215- Bug #1512695: cPickle.loads could crash if it was interrupted with
1216 a KeyboardInterrupt.
1217
Neal Norwitza12aa882006-07-06 06:45:08 +00001218- Bug #1296433: parsing XML with a non-default encoding and
1219 a CharacterDataHandler could crash the interpreter in pyexpat.
1220
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001221- Patch #1516912: improve Modules support for OpenVMS.

1227
Tim Peters32a83612006-07-10 21:08:24 +00001228- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001229 Previously, the slight difference could cause compilation errors of the
1230 'zlib' module on systems with more than one version of zlib.
1231
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001232- The MSI compileall step was fixed to also support a TARGETDIR
1233 with spaces in it.
1234
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001235- Bug #1517388: sqlite3.dll is now installed on Windows independent
1236 of Tcl/Tk.
1237
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001238- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001239 trying to be installed even though it's empty.

1263Core and builtins
1264-----------------
1265
Georg Brandla56b9152006-06-19 06:35:54 +00001266- Patch #1507676: Error messages returned by invalid abstract object operations
1267 (such as iterating over an integer) have been improved and now include the
1268 type of the offending object to help with debugging.
1269
Brett Cannonea3912b2006-06-13 21:46:41 +00001270- Bug #992017: A classic class that defined a __coerce__() method that returned
1271 its arguments swapped would infinitely recurse and segfault the interpreter.
1272
Neal Norwitz909eb122006-06-12 02:13:21 +00001273- Fix the socket tests so they can be run concurrently.
1274
Neal Norwitzb9845e72006-06-12 02:11:18 +00001275- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001276 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001277
Brett Cannon22565aa2006-06-09 22:31:23 +00001278- Bug #532646: object.__call__() will continue looking for the __call__
1279 attribute on objects until one without one is found. This leads to recursion
1280 when you take a class and set its __call__ attribute to an instance of the
1281 class. Originally fixed for classic classes, but this fix is for new-style.
1282 Removes the infinite_rec_3 crasher.
1283
Georg Brandl24250812006-06-09 18:45:48 +00001284- The string and unicode methods startswith() and endswith() now accept
1285 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1286
Brett Cannonde3b0522006-06-08 17:00:45 +00001287- Buffer objects, at the C level, never used the char buffer
1288 implementation even when the char buffer for the wrapped object was
1289 explicitly requested (originally returned the read or write buffer).
1290 Now a TypeError is raised if the char buffer is not present but is
1291 requested.
1292
Georg Brandlddbaa662006-06-04 21:56:52 +00001293- Patch #1346214: Statements like "if 0: suite" are now again optimized
1294 away like they were in Python 2.4.
1295
Georg Brandlb7c8f542006-05-27 12:30:25 +00001296- Builtin exceptions are now full-blown new-style classes instead of
1297 instances pretending to be classes, which speeds up exception handling
1298 by about 80% in comparison to 2.5a2.
1299
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001300- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1301 Unicode 4.1.
1302
Georg Brandlf4ef1162006-05-26 18:03:31 +00001303- Patch #921466: sys.path_importer_cache is now used to cache valid and
1304 invalid file paths for the built-in import machinery which leads to
1305 fewer open calls on startup.
1306
Tim Peters696cf432006-05-24 21:10:40 +00001307- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1308 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1309 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1310 the number of input digits (it was and remains linear-time for bases
1311 2, 4, 8, 16 and 32).
1312
Tim Petersb713ec22006-05-23 18:45:30 +00001313- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1314 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1315 an integer close to ``sys.maxint``. This was repaired by patch
1316 #1335972, which also gives a nice speedup.
1317
Richard Jonescebbefc2006-05-23 18:28:17 +00001318- Patch #1337051: reduced size of frame objects.
1319
1320- PyErr_NewException now accepts a tuple of base classes as its
1321 "base" parameter.
1322
Richard Jones7c88dcc2006-05-23 10:37:38 +00001323- Patch #876206: function call speedup by retaining allocated frame
1324 objects.
1325
Georg Brandl7b90e162006-05-18 07:01:27 +00001326- Bug #1462152: file() now checks more thoroughly for invalid mode
1327 strings and removes a possible "U" before passing the mode to the
1328 C library function.
1329
Neal Norwitz1004a532006-05-15 07:17:23 +00001330- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1331
Neal Norwitz373f0a72006-05-15 07:04:36 +00001332- Bug #1487966: Fix SystemError with conditional expression in assignment
1333
Martin v. Löwis879768d2006-05-11 13:28:43 +00001334- WindowsError now has two error code attributes: errno, which carries
1335 the error values from errno.h, and winerror, which carries the error
1336 values from winerror.h. Previous versions put the winerror.h values
1337 (from GetLastError()) into the errno attribute.
1338
Martin v. Löwis77736712006-05-04 05:51:03 +00001339- Patch #1475845: Raise IndentationError for unexpected indent.
1340
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001341- Patch #1479181: split open() and file() from being aliases for each other.
1342
Tim Peters44bd9862006-06-01 13:49:23 +00001343- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1344 methods were always silently ignored by dictionaries when comparing keys.
1345 They are now passed through (except when using the C API function
1346 ``PyDict_GetItem()``, whose semantics did not change).
1347
1348- Bug #1456209: In some obscure cases it was possible for a class with a
1349 custom ``__eq__()`` method to confuse dict internals when class instances
1350 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1351 No, you don't have any code that did this ;-)

1359
Brett Cannon6ee7d012006-06-08 16:23:04 +00001360- Change binascii.hexlify to accept a read-only buffer instead of only a char
1361 buffer and actually follow its documentation.
1362
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001363- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1364
Nick Coghlanc649ec52006-05-29 12:43:05 +00001365- Patch #1478788 (modified version): The functional extension module has
1366 been renamed to _functools and a functools Python wrapper module added.
1367 This provides a home for additional function related utilities that are
1368 not specifically about functional programming. See PEP 309.
1369
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001370- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001374- Patch #1435422: zlib's compress and decompress objects now have a
1375 copy() method.
1376
Andrew MacIntyre92913322006-06-13 15:04:24 +00001377- Patch #1454481: thread stack size is now tunable at runtime for thread
1378 enabled builds on Windows and systems with Posix threads support.
1379
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001380- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1381 (up to the system limit of 32K characters).
1382
1383- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1384 As a result, these functions now raise WindowsError instead of OSError.
1385
Tim Peters7a822da2006-05-25 21:50:17 +00001386- ``time.clock()`` on Win64 should use the high-performance Windows
1387 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1388 Windows platforms).
1389
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001390- Calling Tk_Init twice is refused if the first call failed as that
1391 may deadlock.
1392
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001393- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1394 accept it without potentially using an uninitialized pointer.
1395
1396- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1397 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +00001403- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1404 parameter is supplied. [SF pybsddb bug #1477863]
1405
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001406- bsddb: the __len__ method of a DB object has been fixed to return correct
1407 results. It could previously incorrectly return 0 in some cases.
1408 Fixes SF bug 1493322 (pybsddb bug 1184012).
1409
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001410- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1411 aborts the db transaction safely when a modifier callback fails.
1412 Fixes SF python patch/bug #1408584.
1413
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001414- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001415 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001416 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1417 database calls that would previously deadlock. [SF python bug #775414]
1418

Martin v. Löwisd8251432006-06-14 05:21:04 +00001446- Patch #1455898: The MBCS codec now supports the incremental mode for
1447 double-byte encodings.
1448
Tim Peters43898b42006-06-14 04:09:25 +00001449- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1450 guarantee that adjacent triples in the return list always describe
1451 non-adjacent blocks. Previously, a pair of matching blocks could end
1452 up being described by multiple adjacent triples that formed a partition
1453 of the matching pair.
1454
Greg Ward0e0c9f42006-06-11 16:24:11 +00001455- Bug #1498146: fix optparse to handle Unicode strings in option help,

1461 clarify docs.
1462
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001463- The wsgiref package has been added to the standard library.
1464
Nick Coghlan676725d2006-06-08 13:54:49 +00001465- The functions update_wrapper() and wraps() have been added to the functools
1466 module. These make it easier to copy relevant metadata from the original
1467 function when writing wrapper functions.
1468
Tim Petersd6a9eef2006-06-05 01:48:21 +00001469- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1470 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001471

1473 for lookup.
1474
Tim Petersd609b1a2006-06-02 23:22:51 +00001475- The functions in the ``pprint`` module now sort dictionaries by key
1476 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1477 if and only if its display required more than one line, although that
1478 wasn't documented. The new behavior increases predictability; e.g.,
1479 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1480
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001481- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1482 (thanks for J. J. Lee).
1483
Georg Brandl2b330372006-05-28 20:23:12 +00001484- Patch #1496206: improve urllib2 handling of passwords with respect to
1485 default HTTP and HTTPS ports.
1486
George Yoshidaf3c65de2006-05-28 16:39:09 +00001487- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1488
Bob Ippolito7298f272006-05-23 18:43:47 +00001489- Patch #1281707: speed up gzip.readline.
1490
Georg Brandlb89316f2006-05-17 15:51:16 +00001491- Patch #1180296: Two new functions were added to the locale module:
1492 format_string() to get the effect of "format % items" but locale-aware,
1493 and currency() to format a monetary number with currency sign.
1494
Georg Brandle3a25832006-05-17 14:56:04 +00001495- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1496 and several features added, such as speed and geometry control.
1497
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001498- Patch #1488881: add support for external file objects in bz2 compressed
1499 tarfiles.
1500
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001501- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1502 stdout arguments, making it possible to redirect input and output
1503 for remote debugging.
1504
1505- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1506 a couple of issues, notably handling of long file names using the
1507 GNU LONGNAME extension.
1508
1509- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1510 new flag when ``name`` is already the name of an option flag.
1511
1512- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1513 package.
1514
1515- Patch #1472854: make the rlcompleter.Completer class usable on non-
1516 UNIX platforms.
1517
1518- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1519
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001520- Bug #1472827: correctly escape newlines and tabs in attribute values in
1521 the saxutils.XMLGenerator class.

1550
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001551What's New in Python 2.5 alpha 2?
1552=================================
1553
1554*Release date: 27-APR-2006*
1555
1556Core and builtins
1557-----------------
1558
Thomas Heller1b046642006-04-18 18:51:06 +00001559- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1560 by converting these apis from macros into exported functions again:
1561
1562 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1563 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1564 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1565 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1566 PyRun_String Py_CompileString
1567
Martin v. Löwis45294a92006-04-18 06:24:08 +00001568- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1569
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001570- All uses of PyStructSequence_InitType have been changed to initialize
1571 the type objects only once, even if the interpreter is initialized
1572 multiple times.
1573
Neal Norwitz61546162006-04-14 05:20:28 +00001574- Bug #1454485, array.array('u') could crash the interpreter. This was
1575 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1576 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1577
1578- Py_UNICODE is unsigned. It was always documented as unsigned, but
1579 due to a bug had a signed value in previous versions.
1580
Tim Peters3a5e8b12006-04-11 01:44:07 +00001581- Patch #837242: ``id()`` of any Python object always gives a positive
1582 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1583 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001584 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001585 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001586
Tim Peters3a5e8b12006-04-11 01:44:07 +00001587 def __hash__(self):
1588 return id(self) # WRONG
1589
1590 because a hash result must be a (short) Python int but it was always
1591 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001592 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001593 was always usable as a hash value before this patch. That's no longer
1594 necessarily so.
1595
1596- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001597 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001598 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001599 #1454844)
1600
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001601- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1602 involving generators that have paused outside of any ``try`` or ``with``
1603 blocks. (In 2.5a1, a paused generator that was part of a reference
1604 cycle could not be garbage collected, regardless of whether it was
1605 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001606
Anthony Baxter51bcb682006-04-05 14:51:42 +00001607Extension Modules
1608-----------------
1609
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001610- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1611 is a macro.
1612
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001613- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1614 fails with an error condition.
1615
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001616- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1617
1618- Bug #1117761: bsddb.*open() no longer raises an exception when using
1619 the cachesize parameter.
1620
1621- Bug #1149413: bsddb.*open() no longer raises an exception when using
1622 a temporary db (file=None) with the 'n' flag to truncate on open.
1623
1624- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1625 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001626
Armin Rigoa9017c32006-04-19 11:50:27 +00001627- Patch #1062014: AF_UNIX sockets under Linux have a special
1628 abstract namespace that is now fully supported.
1629
Anthony Baxter51bcb682006-04-05 14:51:42 +00001630Library
1631-------
1632
Peter Astrand7d1d4362006-07-14 14:04:45 +00001633- Bug #1223937: subprocess.CalledProcessError reports the exit status
1634 of the process using the returncode attribute, instead of
1635 abusing errno.
1636
Tim Peters711bf302006-04-25 03:31:36 +00001637- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1638 a doctest to be skipped (the code is not run, and the expected output
1639 or exception is ignored).
1640
Nick Coghlanda2268f2006-04-24 04:37:15 +00001641- Fixed contextlib.nested to cope with exceptions being raised and
1642 caught inside exit handlers.
1643
Greg Wardab05edc2006-04-23 03:47:58 +00001644- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1645 hex, octal, or binary; add ``append_const`` action; keep going if
1646 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1647 added ``epilog`` for better help generation).
1648
Tim Peters21fbd572006-04-21 21:18:10 +00001649- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1650 called from a thread spawned as a side effect of importing a module.
1651
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001652- The pydoc module now supports documenting packages contained in
1653 .zip or .egg files.
1654
1655- The pkgutil module now has several new utility functions, such
1656 as ``walk_packages()`` to support working with packages that are either
1657 in the filesystem or zip files.
1658
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001659- The mailbox module can now modify and delete messages from
1660 mailboxes, in addition to simply reading them. Thanks to Gregory
1661 K. Johnson for writing the code, and to the 2005 Google Summer of
1662 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001663
Tim Petersc7605f22006-04-17 21:12:33 +00001664- The ``__del__`` method of class ``local`` in module ``_threading_local``
1665 returned before accomplishing any of its intended cleanup.
1666
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001667- Patch #790710: Add breakpoint command lists in pdb.
1668
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001669- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1670
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001671- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1672
Anthony Baxtere29002c2006-04-12 12:07:31 +00001673- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1674 Windows. Bug #1469163.
1675
Phillip J. Eby47032112006-04-11 01:07:43 +00001676- The warnings, linecache, inspect, traceback, site, and doctest modules
1677 were updated to work correctly with modules imported from zipfiles or
1678 via other PEP 302 __loader__ objects.
1679
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001680- Patch #1467770: Reduce usage of subprocess._active to processes which
1681 the application hasn't waited on.
1682
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001683- Patch #1462222: Fix Tix.Grid.
1684
Neal Norwitza31bf182006-04-09 03:35:43 +00001685- Fix exception when doing glob.glob('anything*/')
1686
Skip Montanaro262fb922006-04-21 02:31:07 +00001687- The pstats.Stats class accepts an optional stream keyword argument to
1688 direct output to an alternate file-like object.
1689
Anthony Baxter51bcb682006-04-05 14:51:42 +00001690Build
1691-----
1692
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001693- The Makefile now has a reindent target, which runs reindent.py on
1694 the library.
1695
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001696- Patch #1470875: Building Python with MS Free Compiler
1697
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001698- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001699
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001700- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1701 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001702 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001703 CXX from --with-cxx-main, see description in README.
1704
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001705- Patch #1429775: Link extension modules with the shared libpython.
1706
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001707- Fixed a libffi build problem on MIPS systems.
1708
Tim Peters8931ff12006-05-13 23:28:20 +00001709- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1710 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1711 and "%zu" for unsigned integers of type ``size_t``.
1712
Anthony Baxter51bcb682006-04-05 14:51:42 +00001713Tests
1714-----
1715
Nick Coghlanda2268f2006-04-24 04:37:15 +00001716- test_contextlib now checks contextlib.nested can cope with exceptions
1717 being raised and caught inside exit handlers.
1718
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001719- test_cmd_line now checks operation of the -m and -c command switches
1720
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001721- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1722 it separately and by hand. It also wasn't cleaning up its changes to
1723 the current Decimal context.
1724
Thomas Woutersabd08882006-04-26 15:53:30 +00001725- regrtest.py now has a -M option to run tests that test the new limits of
1726 containers, on 64-bit architectures. Running these tests is only sensible
1727 on 64-bit machines with more than two gigabytes of memory. The argument
1728 passed is the maximum amount of memory for the tests to use.
1729
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001730Tools

1737-------------
1738
Tim Petersb06d28c2006-05-12 01:57:59 +00001739- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1740
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001741- PEP 343: Added Context Types section to the library reference
1742 and attempted to bring other PEP 343 related documentation into
1743 line with the implementation and/or python-dev discussions.
1744
Tim Peters8dc73d22006-04-24 02:03:16 +00001745- Bug #1337990: clarified that ``doctest`` does not support examples
1746 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001749What's New in Python 2.5 alpha 1?
1750=================================
1751
Anthony Baxterebed3f62006-04-03 15:03:44 +00001752*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001753
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001754Core and builtins
1755-----------------
1756
Nick Coghlan43832302006-04-23 17:04:07 +00001757- PEP 338: -m command line switch now delegates to runpy.run_module
1758 allowing it to support modules in packages and zipfiles
1759
Martin v. Löwisc661b882006-04-20 04:54:23 +00001760- On Windows, .DLL is not an accepted file name extension for
1761 extension modules anymore; extensions are only found if they
1762 end in .PYD.
1763
Martin v. Löwisea62d252006-04-03 10:56:49 +00001764- Bug #1421664: sys.stderr.encoding is now set to the same value as
1765 sys.stdout.encoding.
1766
Neal Norwitz92e212f2006-04-03 04:48:37 +00001767- __import__ accepts keyword arguments.
1768
Georg Brandlccadf842006-03-31 18:54:53 +00001769- Patch #1460496: round() now accepts keyword arguments.
1770
Anthony Baxter262c00a2006-03-30 10:53:17 +00001771- Fixed bug #1459029 - unicode reprs were double-escaped.
1772
Hye-Shik Changd478f342006-03-23 12:32:36 +00001773- Patch #1396919: The system scope threads are reenabled on FreeBSD
1774 5.4 and later versions.
1775
Neal Norwitze98ccf62006-03-23 05:39:47 +00001776- Bug #1115379: Compiling a Unicode string with an encoding declaration
1777 now gives a SyntaxError.
1778
Georg Brandlabd1ff82006-03-18 07:59:59 +00001779- Previously, Python code had no easy way to access the contents of a
1780 cell object. Now, a ``cell_contents`` attribute has been added
1781 (closes patch #1170323).
1782
Tim Peterscf79aac2006-03-16 01:14:46 +00001783- Patch #1123430: Python's small-object allocator now returns an arena to
1784 the system ``free()`` when all memory within an arena becomes unused
1785 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1786 freed. Some applications will see a drop in virtual memory size now,
1787 especially long-running applications that, from time to time, temporarily
1788 use a large number of small objects. Note that when Python returns an
1789 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001790 platform C library will in turn return that memory to the operating system.
1791 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001792 appears to be effective at least on Microsoft C and gcc-based systems.
1793 Thanks to Evan Jones for hard work and patience.
1794
Georg Brandl533ff6f2006-03-08 18:09:27 +00001795- Patch #1434038: property() now uses the getter's docstring if there is
1796 no "doc" argument given. This makes it possible to legitimately use
1797 property() as a decorator to produce a read-only property.
1798
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001799- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1800 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1801 of requiring an int or long in slicing and a few other contexts, enabling
1802 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1803
Neal Norwitz995acdf2006-03-07 05:01:00 +00001804- Fixed various bugs reported by Coverity's Prevent tool.
1805
Brett Cannonbf364092006-03-01 04:25:17 +00001806- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1807 new exception base class, BaseException, which has a new message attribute.
1808 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1809 Raising a string exception now raises a DeprecationWarning.
1810
Thomas Woutersfb609f42006-02-28 16:37:25 +00001811- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1812 explicitly relative, using 'from .module import name' to mean 'from the same
1813 package as this module is in. Imports without dots still default to the
1814 old relative-then-absolute, unless 'from __future__ import
1815 absolute_import' is used.
1816
Brett Cannona7446e32006-02-27 23:39:10 +00001817- Properly check if 'warnings' raises an exception (usually when a filter set
1818 to "error" is triggered) when raising a warning for raising string
1819 exceptions.
1820
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001821- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001822 The name was removed from Include/code.h.
1823
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001824- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001825
Guido van Rossum1968ad32006-02-25 22:38:04 +00001826- Patch 1433928:
1827 - The copy module now "copies" function objects (as atomic objects).
1828 - dict.__getitem__ now looks for a __missing__ hook before raising
1829 KeyError.
1830
Tim Peters84ef21c2006-02-28 20:39:06 +00001831- PEP 343: with statement implemented. Needs ``from __future__ import
1832 with_statement``. Use of 'with' as a variable will generate a warning.
1833 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001834 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001835 The following objects have __context__ methods:
1836 - The built-in file type.
1837 - The thread.LockType type.
1838 - The following types defined by the threading module:
1839 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1840 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001841
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001842- Fix the encodings package codec search function to only search
1843 inside its own package. Fixes problem reported in patch #1433198.
1844
1845 Note: Codec packages should implement and register their own
1846 codec search function. PEP 100 has the details.
1847
Tim Peters9ea89d22006-06-04 03:26:02 +00001848- PEP 353: Using ``Py_ssize_t`` as the index type.
1849
1850- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1851 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1852 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1853 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1854 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001855
Neal Norwitzfc76d632006-01-10 06:03:13 +00001856- Patch #1400181, fix unicode string formatting to not use the locale.
1857 This is how string objects work. u'%f' could use , instead of .
1858 for the decimal point. Now both strings and unicode always use periods.
1859
Neal Norwitz671b9e32006-01-09 07:07:12 +00001860- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1861 configure would break checking curses.h.
1862
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001863- Bug #959576: The pwd module is now builtin. This allows Python to be
1864 built on UNIX platforms without $HOME set.
1865
Neal Norwitzc10978f2005-12-19 06:07:16 +00001866- Bug #1072182, fix some potential problems if characters are signed.
1867
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001868- Bug #889500, fix line number on SyntaxWarning for global declarations.
1869
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001870- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1871
Neal Norwitze7214a12005-12-18 05:03:17 +00001872- Support for converting hex strings to floats no longer works.
1873 This was not portable. float('0x3') now raises a ValueError.
1874
Barry Warsaw2a38a862005-12-18 01:27:35 +00001875- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001876 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001877 is now displayed in interactive prompt banner.
1878
Georg Brandlfa166682005-12-17 21:45:17 +00001879- Implementation of PEP 341 - Unification of try/except and try/finally.
1880 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001881 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001882
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001883- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1884 now encodes backslash correctly.
1885
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001886- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1887
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001888- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001889 and long longs.
1890
Neal Norwitz67715f02005-11-09 06:59:35 +00001891- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001892 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001893 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001894
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001895- Replaced most Unicode charmap codecs with new ones using the
1896 new Unicode translate string feature in the builtin charmap
1897 codec; the codecs were created from the mapping tables available
1898 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1899 encodings now include a mapping for the Apple logo)
1900
Tim Peterse3547fd2005-12-16 23:13:57 +00001901- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001902
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001903- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001904
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001905- A new AST parser implementation was completed. The abstract
1906 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001907 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001908
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001909- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001910 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1911
Neal Norwitz708e51a2005-10-03 04:48:15 +00001912- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1913
Neal Norwitz11bd1192005-10-03 00:54:56 +00001914- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1915 Provide a warning when a directory is passed on the command line.
1916
Neal Norwitz40d37812005-10-02 01:48:49 +00001917- Fix segfault with invalid coding.
1918
1919- SF bug #772896: unknown encoding results in MemoryError.
1920
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001921- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001922 supported a __len__() method which evaluated to False when the iterator
1923 was empty.
1924
Guido van Rossum630db602005-09-20 18:49:54 +00001925- On 64-bit platforms, when __len__() returns a value that cannot be
1926 represented as a C int, raise OverflowError.
1927
Skip Montanarof8948ca2005-09-19 03:54:46 +00001928- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001929 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001930
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001931- SF bug #893549: parsing keyword arguments was broken with a few format
1932 codes.
1933
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001934- Changes donated by Elemental Security to make it work on AIX 5.3
1935 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1936 bug #105470: test_pwd fails on 64bit system (Opteron).
1937
Guido van Rossum539c6622005-09-14 17:49:54 +00001938- Changes donated by Elemental Security to make it work on HP-UX 11 on
1939 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1940
Georg Brandl4550b8d2005-08-26 06:43:52 +00001941- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001942 (fixes bug #1119418).
1943
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001944- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1945
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001946- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1947 exceptions that cause a function to exit.
1948
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001949- The implementation of set() and frozenset() was revised to use its
1950 own internal data structure. Memory consumption is reduced by 1/3
1951 and there are modest speed-ups as well. The API is unchanged.
1952
Tim Petersde7990b2005-07-17 23:45:23 +00001953- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1954
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001955- SF bug #1229429: PyObject_CallMethod failed to decrement some
1956 reference counts in some error exit cases.
1957
Tim Petersecc6e6a2005-07-10 22:30:55 +00001958- SF bug #1185883: Python's small-object memory allocator took over
1959 a block managed by the platform C library whenever a realloc specified
1960 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001961 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001962 portable way to copy data from the C-managed block into Python's
1963 small-object space without risking a memory fault. Python's small-object
1964 realloc now leaves such blocks under the control of the platform C
1965 realloc.
1966
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001967- SF bug #1232517: An overflow error was not detected properly when
1968 attempting to convert a large float to an int in os.utime().
1969
Raymond Hettinger3296e692005-06-29 23:29:56 +00001970- SF bug #1224347: hex longs now print with lowercase letters just
1971 like their int counterparts.
1972
Michael W. Hudson188d4362005-06-20 16:52:57 +00001973- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1974 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1975 interpreter states; back out that fix and do a better job (see
1976 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1977 for a longer write-up of the problem).
1978
Michael W. Hudsondf888462005-06-03 14:41:55 +00001979- SF patch #1180995: marshal now uses a binary format by default when
1980 serializing floats.
1981
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001982- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1983 the routines that promise to produce IEEE 754 binary representations
1984 of floats now simply copy bytes around.
1985
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001986- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1987 278.
1988
Brett Cannonc3647ac2005-04-26 03:45:26 +00001989- patch #1109424: int, long, float, complex, and unicode now check for the
1990 proper magic slot for type conversions when subclassed. Previously the
1991 magic slot was ignored during conversion. Semantics now match the way
1992 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001993 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001994 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001995 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001996
Barry Warsawc8d907c2005-04-19 23:43:40 +00001997- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1998 NULL, now raise an AttributeError when attempting to set or delete the
1999 attribute. Previously a TypeError was raised, but this was inconsistent
2000 with the equivalent pure-Python implementation.
2001
Michael W. Hudson774479c2005-04-18 08:46:17 +00002002- It is now safe to call PyGILState_Release() before
2003 PyEval_InitThreads() (note that if there is reason to believe there
2004 are multiple threads around you still must call PyEval_InitThreads()
2005 before using the Python API; this fix is for extension modules that
2006 have no way of knowing if Python is multi-threaded yet).
2007
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002008- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2009 disabled caused a crash.
2010
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002011- Bug #1165306: instancemethod_new allowed the creation of a method
2012 with im_class == im_self == NULL, which caused a crash when called.
2013
Tim Petersecc6e6a2005-07-10 22:30:55 +00002014- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002015 fixes the crash seen in bug #1165761
2016
Raymond Hettinger96229b12005-03-11 06:49:40 +00002017- Added two new builtins, any() and all().
2018
Brett Cannon409d8f22005-03-05 06:47:57 +00002019- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002020 (e.g., ``class C(): pass`` is no longer a syntax error).
2021 Patch #1176012 added support to the 'parser' module and 'compiler' package
2022 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002023
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002024- Patch #1115086: Support PY_LONGLONG in structmember.
2025
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002026- Bug #1155938: new style classes did not check that __init__() was
2027 returning None.
2028
Tim Petersecc6e6a2005-07-10 22:30:55 +00002029- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002030 ('\') with a specific error message.
2031
Martin v. Löwisff232d72005-03-03 09:24:38 +00002032- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2033
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002034- Bug #1124295: the __name__ attribute of file objects was
2035 inadvertently made inaccessible in restricted mode.
2036
Tim Petersecc6e6a2005-07-10 22:30:55 +00002037- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002038 an ferror() call.
2039
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002040- min() and max() now support key= arguments with the same meaning as in
2041 list.sort().
2042
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002043- The peephole optimizer now performs simple constant folding in expressions:
2044 (2+3) --> (5).
2045
Raymond Hettingera422c342005-01-11 03:03:27 +00002046- set and frozenset objects can now be marshalled. SF #1098985.
2047
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002048- Bug #1077106: Poor argument checking could cause memory corruption
2049 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002050
Jeremy Hyltonab630502005-02-04 18:44:06 +00002051- The parser did not complain about future statements in illegal
2052 positions. It once again reports a syntax error if a future
2053 statement occurs after anything other than a doc string.
2054
Neil Schemenauercf52c072005-08-12 17:34:58 +00002055- Change the %s format specifier for str objects so that it returns a
2056 unicode instance if the argument is not an instance of basestring and
2057 calling __str__ on the argument returns a unicode instance.
2058
Tim Petersf4e69282006-02-27 17:15:31 +00002059- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2060 current thread state when the auto-GIL-state machinery knows about
2061 it (since the thread state is being deleted, continuing to remember it
2062 can't help, but can hurt if another thread happens to get created with
2063 the same thread id).

2196 the request code argument, which results in more C-like behaviour
2197 for large or negative values.
2198
Tim Petersecc6e6a2005-07-10 22:30:55 +00002199- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002239- the cPickle module no longer accepts the deprecated None option in the
2240 args tuple returned by __reduce__().
2241
Raymond Hettingerb2594052004-12-05 09:25:51 +00002242- itertools.islice() now accepts None for the start and step arguments.
2243 This allows islice() to work more readily with slices:
2244 islice(s.start, s.stop, s.step)
2245
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002246- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002255- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2256 been renamed to have only a single underscore prefix. This was done to
2257 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002258
Nick Coghlan43832302006-04-23 17:04:07 +00002259- PEP 338: new module runpy defines a run_module function to support
2260 executing modules which provide access to source code or a code object
2261 via the PEP 302 import mechanisms.
2262
Anthony Baxter93f5b932006-04-03 08:05:07 +00002263- The email module's parsedate_tz function now sets the daylight savings

2271 in attribute values.
2272
Anthony Baxterc51ee692006-04-01 00:57:31 +00002273- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002274 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002275 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002276 module will not be built.
2277
Tim Petersc17976e2006-04-01 00:26:53 +00002278- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2279 aren't officially supported here, and trying to use them will probably
2280 raise an exception some day. But dicts have been allowed, and "mostly
2281 worked", so support for them won't go away without warning.
2282
Georg Brandl338ef7d2006-03-31 18:42:16 +00002283- Bug #1445068: getpass.getpass() can now be given an explicit stream
2284 argument to specify where to write the prompt.
2285
Georg Brandl22ec80b2006-03-31 18:25:44 +00002286- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2301
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002302- email 4.0 package now integrated. This is largely the same as the email 3.0
2303 package that was included in Python 2.3, except that PEP 8 module names are
2304 now used (e.g. mail.message instead of email.Message). The MIME classes
2305 have been moved to a subpackage (e.g. email.mime.text instead of
2306 email.MIMEText). The old names are still supported for now. Several
2307 deprecated Message methods have been removed and lots of bugs have been
2308 fixed. More details can be found in the email package documentation.
2309
Walter Dörwald40108c92006-03-27 08:15:44 +00002310- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2311 (a subclass of tuple) that provides incremental decoders and encoders
2312 (a way to use stateful codecs without the stream API). Python functions
2313 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2314 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()

2398
2399 "The consensus of researchers in this area (at least as
2400 expressed at the NIST Hash Function Workshop 10/31/05),
2401 is that SHA-256 is a good choice for the time being, but
2402 that research should continue, and other alternatives may
2403 arise from this research. The larger SHA's also seem OK."

Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002576
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002577- Bug #1110478: Revert os.environ.update to do putenv again.
2578
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002579- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2580
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002581- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2582
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002583- Enhancements to the csv module:
2584
2585 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002586 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002587 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002588 + Dialect parameter parsing has been re-implemented to improve error
2589 reporting.
2590 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2591 dictates.
2592 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002593 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002594 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002595 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2596 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002597 + reader now allows \r characters to be quoted (previously it only allowed
2598 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002599 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002600 + Dialect classes passed to the module are no longer instantiated by
2601 the module before being parsed (the former validation scheme required
2602 this, but the mechanism was unreliable).
2603 + The dialect registry now contains instances of the internal
2604 C-coded dialect type, rather than references to python objects.
2605 + the internal c-coded dialect type is now immutable.
2606 + register_dialect now accepts the same keyword dialect specifications
2607 as the reader and writer, allowing the user to register dialects
2608 without first creating a dialect class.
2609 + a configurable limit to the size of parsed fields has been added -
2610 previously, an unmatched quote character could result in the entire
2611 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002612 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002613 the parser field size limit (returning the former limit). The initial
2614 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002615 + A line_num attribute has been added to the reader object, which tracks
2616 the number of lines read from the source iterator. This is not
2617 the same as the number of records returned, as records can span
2618 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002619 + reader and writer objects were not being registered with the cyclic-GC.
2620 This has been fixed.
2621
Brett Cannone6539c42005-01-08 02:43:53 +00002622- _DummyThread objects in the threading module now delete self.__block that is
2623 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2624 lock primitives tend to be limited in number and thus should not be wasted on
2625 a _DummyThread object. Fixes bug #1089632.
2626
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002627- The imghdr module now detects Exif files.
2628
Raymond Hettinger6065d322004-12-20 23:51:53 +00002629- StringIO.truncate() now correctly adjusts the size attribute.
2630 (Bug #951915).
2631
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002632- locale.py now uses an updated locale alias table (built using
2633 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2634 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002635 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002636
Raymond Hettinger3557f422004-12-07 12:02:02 +00002637- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2638
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002639- the pickle module no longer accepts the deprecated None option in the
2640 args tuple returned by __reduce__().
2641
Brett Cannon84667c02004-12-07 03:25:18 +00002642- optparse now optionally imports gettext. This allows its use in setup.py.
2643
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002644- the pickle module no longer uses the deprecated bin parameter.
2645
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002646- the shelve module no longer uses the deprecated binary parameter.
2647
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002648- the pstats module no longer uses the deprecated ignore() method.
2649
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002650- the filecmp module no longer uses the deprecated use_statcache argument.
2651
Raymond Hettinger664347b2004-12-04 21:21:53 +00002652- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2653 extended or overridden by subclasses. Formerly, the subclassed method would
2654 be ignored by the rest of the module. (Bug #1078905).
2655
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002656- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002657 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002658
Walter Dörwald36733692004-12-22 12:50:50 +00002659- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2660 once when a size argument is given. This prevents a buffer overflow in the
2661 tokenizer with very long source lines.
2662
Barry Warsaw538561e2006-01-01 21:48:54 +00002663- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2664 immediately after creating the object, without any intervening
2665 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002666
Skip Montanaro05885812005-01-16 20:48:27 +00002667- The reconvert.quote function can now emit triple-quoted strings. The
2668 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002669
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002670- ``UserString.MutableString`` now supports negative indices in
2671 ``__setitem__`` and ``__delitem__``
2672
Greg Ward40407942005-03-05 02:53:17 +00002673- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2674 correctly.
2675
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002676- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2677 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2678 character even if the user has passed a size parameter to get a proper
2679 line ending. Remove the special handling of a "\r\n" that has been split
2680 between two lines.
2681
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002682- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2683 about illegal code points. The codec now supports PEP 293 style error
2684 handlers.
2685
Walter Dörwald78a78b02005-09-01 12:04:29 +00002686- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002687 from the input stream, so that the output is a byte string in the correct
2688 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002689
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002690- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2691 considering it exactly like a '*'.
2692
Walter Dörwald007f8df2005-10-09 19:42:27 +00002693- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2694 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002695
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002696- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2697
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002698- Patch #1413711: Certain patterns of differences were making difflib
2699 touch the recursion limit.
2700
Walter Dörwald58917a62006-03-31 15:26:22 +00002701- Bug #947906: An object oriented interface has been added to the calendar
2702 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002703 called as a script (e.g. via ``python -mcalendar``). Localized month and
2704 weekday names can be ouput (even if an exotic encoding is used) using
2705 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002706
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002707Build
2708-----
2709
Neal Norwitz602d3392006-03-31 08:21:40 +00002710- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2711 by using -mieee gcc option.
2712

2714
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002715- Build support for Win64-AMD64 was added.
2716
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002717- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2718
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002719- Patch #881820: look for openpty and forkpty also in libbsd.
2720
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002721- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2722 The zlib module is now builtin on Windows.
2723
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002724- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2725
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002726- Bug #1189330: configure did not correctly determine the necessary
2727 value of LINKCC if python was built with GCC 4.0.
2728
Trent Mick8321b422005-07-26 02:29:21 +00002729- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2730 vulnerability in zlib 1.2.1 and 1.2.2.
2731
Brett Cannon08cd5982005-04-24 22:26:38 +00002732- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2733 flags that change binary compatibility. Changes were also made to
2734 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002735 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002736
Bob Ippolitoed233462005-03-29 13:47:59 +00002737- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2738 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2739 no longer exists). This configure patch makes things right.
2740
Martin v. Löwise2713be2005-03-08 15:03:08 +00002741- Bug #1158607: Build with --disable-unicode again.
2742
Brett Cannon46d96232005-02-16 00:07:19 +00002743- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2744 defined. Discovered as a result of not being able to build on OS X.
2745
Brett Cannon516592f2004-12-07 00:42:59 +00002746- setup.py now uses the directories specified in LDFLAGS using the -L option
2747 and in CPPFLAGS using the -I option for adding library and include
2748 directories, respectively, for compiling extension modules against. This has
2749 led to the core being compiled using the values in CPPFLAGS. It also removes
2750 the need for the special-casing of both DarwinPorts and Fink for darwin since
2751 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2752 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2753 Fink, ``-I/opt/local/include`` for DarwinPorts).
2754
Brett Cannon43802422005-02-10 20:48:03 +00002755- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2756 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2757 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2758 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002760C API
2761-----
2762
Tim Petersc9d78aa2006-03-26 23:27:58 +00002763- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2764 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2765 is obtained via the ``PyObject_`` family, it must be released via the
2766 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2767 always been officially true, but when Python's small-object allocator was
2768 introduced, an attempt was made to cater to a few extension modules
2769 discovered at the time that obtained memory via ``PyObject_New`` but
2770 released it via ``PyMem_DEL``. It's years later, and if such code still
2771 exists it will fail now (probably with segfaults, but calling wrong
2772 low-level memory management functions can yield many symptoms).
2773
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002774- Added a C API for set and frozenset objects.
2775
Raymond Hettinger66517482004-12-03 11:45:13 +00002776- Removed PyRange_New().
2777
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002778- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2779 mapping argument now. This string is used as a mapping table. Byte values
2780 greater than the length of the string and 0xFFFE are treated as undefined
2781 mappings.
