906-----------------
907
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000908- Make _PyGILState_NoteThreadState() static, it was not used anywhere
909 outside of pystate.c and should not be necessary.
910
Brett Cannon19d76c52006-09-09 07:18:44 +0000911- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
912 allows calling unicode() on exceptions classes directly to succeed.
913
Georg Brandlecab6232006-09-06 06:47:02 +0000914- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
915 Also make sure that every exception class has __module__ set to
916 'exceptions'.
917
Georg Brandl37a9e572006-09-06 06:09:34 +0000918- Bug #1550983: emit better error messages for erroneous relative

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000929- The return tuple from str.rpartition(sep) is (tail, sep, head) where
930 head is the original string if sep was not found.
931
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000932- Bug #1520864: unpacking singleton tuples in list comprehensions and
933 generator expressions (x for x, in ... ) works again. Fixing this problem
934 required changing the .pyc magic number. This means that .pyc files
935 generated before 2.5c2 will be regenerated.

Anthony Baxterb4096662006-08-16 03:42:26 +00001045*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001046
1047Core and builtins
1048-----------------
1049
Neal Norwitz24b6f202006-09-05 04:43:56 +00001050- Fix infinite recursion when subclassing long and overriding __hash__.
1051
1052- Fix concatenation (+=) of long strings.
1053
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001054- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001055 compared equal or unequal to a string and a UnicodeDecodeError
1056 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001057
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001058 Instead, the equal (==) and unequal (!=) comparison operators will
1059 now issue a UnicodeWarning and interpret the two objects as
1060 unequal. The UnicodeWarning can be filtered as desired using
1061 the warning framework, e.g. silenced completely, turned into an
1062 exception, logged, etc.
1063
1064 Note that compare operators other than equal and unequal will still
1065 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001066
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001067- Fix segfault when doing string formatting on subclasses of long.
1068
1069- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1070 with new-style classes.
1071
1072- Fix bug related to __len__ functions returning negative values with
1073 classic classes.
1074
1075- Patch #1538606, Fix __index__() clipping. There were some problems
1076 discovered with the API and how integers that didn't fit into Py_ssize_t
1077 were handled. This patch attempts to provide enough alternatives
1078 to effectively use __index__.
1079
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001080- Bug #1536021: __hash__ may now return long int; the final hash
1081 value is obtained by invoking hash on the long int.
1082
Thomas Hellerab1049c2006-08-08 17:37:00 +00001083- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1084
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001085- Bug #1535165: fixed a segfault in input() and raw_input() when
1086 sys.stdin is closed.
1087
Thomas Heller74d36f02006-08-04 18:17:40 +00001088- On Windows, the PyErr_Warn function is now exported from
1089 the Python dll again.
1090
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001091- Bug #1191458: tracing over for loops now produces a line event
1092 on each iteration. Fixing this problem required changing the .pyc
1093 magic number. This means that .pyc files generated before 2.5c1
1094 will be regenerated.
1095
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001096- Bug #1333982: string/number constants were inappropriately stored
1097 in the byte code and co_consts even if they were not used, ie
1098 immediately popped off the stack.
1099
Georg Brandle9462c72006-08-04 18:03:37 +00001100- Fixed a reference-counting problem in property().

1103Library
1104-------
1105
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001106- Fix a bug in the ``compiler`` package that caused invalid code to be
1107 generated for generator expressions.
1108
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001109- The distutils version has been changed to 2.5.0. The change to
1110 keep it programmatically in sync with the Python version running
1111 the code (introduced in 2.5b3) has been reverted. It will continue
1112 to be maintained manually as static string literal.
1113
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001114- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001115 and this cannot be converted to the required C type, an exception is
1116 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001117 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001118
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001119- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001120 an exception.
1121
Tim Peterscbdd3502006-09-05 01:47:53 +00001122- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001123 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001124 workarounds for clocks with low resolution, to stop the code yielding
1125 duplicate UUIDs.
1126
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001127- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1128 before raising SystemExit, allowing IDLE to honor quit() and exit().
1129
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001130- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1131
Georg Brandl7a1af772006-08-14 21:55:28 +00001132- Patch #1536071: trace.py should now find the full module name of a
1133 file correctly even on Windows.
1134
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001135- logging's atexit hook now runs even if the rest of the module has
1136 already been cleaned up.
1137
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001138- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +00001140- Bug #1531405, format_exception no longer raises an exception if
1141 str(exception) raised an exception.
1142
Neil Schemenauer06ded092006-08-04 16:20:30 +00001143- Fix a bug in the ``compiler`` package that caused invalid code to be
1144 generated for nested functions.

Thomas Heller86720042006-08-14 11:17:48 +00001160- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1161 uses the _as_parameter_ attribute when objects are passed to foreign
1162 function calls. The ctypes version number was changed to 1.0.1.
1163
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001164- Bug #1530559, struct.pack raises TypeError where it used to convert.
1165 Passing float arguments to struct.pack when integers are expected
1166 now triggers a DeprecationWarning.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001203- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1204
Tim Peters4643c2f2006-08-10 22:45:34 +00001205- Bug #1069160. Internal correctness changes were made to
1206 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1207 the documentation was changed to state that the return value
1208 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001211What's New in Python 2.5 beta 3?
1212================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001213
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001214*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001215
1216Core and builtins
1217-----------------
1218
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001219- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001220 returned a long (see PEP 353).
1221
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001222- Bug #1515471: string.replace() accepts character buffers again.
1223
Neal Norwitz07aadb12006-07-30 06:55:48 +00001224- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1225 This provides the proper warning for struct.pack().
1226 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1227
Neal Norwitz0d62a062006-07-30 06:53:31 +00001228- Patch #1531113: Fix augmented assignment with yield expressions.
1229 Also fix a SystemError when trying to assign to yield expressions.
1230
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001231- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1232 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1233 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1234 excessive filesystem operations during imports.
1235
Tim Petersbc24eee2006-07-27 01:14:53 +00001236- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1237 operations on signed longs that are formally undefined by C.
1238 Unfortunately, at least one compiler now cares about that, so complicated
1239 the code to make that compiler happy again.
1240
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001241- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1242
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001243- Patch #1232023: Stop including current directory in search
1244 path on Windows.
1245
Neal Norwitze1fdb322006-07-21 05:32:28 +00001246- Fix some potential crashes found with failmalloc.
1247
Neal Norwitze7563102006-07-17 01:00:16 +00001248- Fix warnings reported by Klocwork's static analysis tool.
1249
Neal Norwitz84be93b2006-07-16 01:50:38 +00001250- Bug #1512814, Fix incorrect lineno's when code within a function
1251 had more than 255 blank lines.
1252
Georg Brandl9dceedb2006-07-12 15:31:17 +00001253- Patch #1521179: Python now accepts the standard options ``--help`` and
1254 ``--version`` as well as ``/?`` on Windows.
1255
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001256- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001257 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001258 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001259
Tim Peters112aad32006-07-19 00:03:19 +00001260- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001261 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001262 new ``sys._current_frames()`` returns a dictionary with one entry,
1263 mapping the faux "thread id" 0 to the current frame.
1264
Ronald Oussoren3075e162006-07-25 20:28:55 +00001265- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001266

1269-------
1270
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001271- Correction of patch #1455898: In the mbcs decoder, set final=False
1272 for stream decoder, but final=True for the decode function.
1273
Georg Brandl07fec3a2006-08-01 18:49:24 +00001274- os.urandom no longer masks unrelated exceptions like SystemExit or
1275 KeyboardInterrupt.
1276
Tim Peters4643c2f2006-08-10 22:45:34 +00001277- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001278 shutil.copytree on Windows
1279
Georg Brandle34ac7c2006-07-30 11:07:23 +00001280- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1281 refers to file descriptors, not file objects.
1282
Tim Peterscbdd3502006-09-05 01:47:53 +00001283- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001284 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001285 #1513611, and probably others.
1286
Georg Brandledd9b0d2006-07-29 09:33:26 +00001287- Bug #1441397: The compiler module now recognizes module and function
1288 docstrings correctly as it did in Python 2.4.
1289
Tim Peters6f681472006-07-27 23:44:37 +00001290- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1291 lost that tests are sorted by name before being run. This rarely
1292 matters for well-written tests, but can create baffling symptoms if
1293 side effects from one test to the next affect outcomes. ``DocTestFinder``
1294 has been changed to sort the list of tests it returns.
1295
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001296- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001297 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001298
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001299- Bug #978833: Really close underlying socket in _socketobject.close.
1300
Georg Brandldb232dc2006-08-20 13:15:43 +00001301- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1302 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001303
Georg Brandlcf0c1722006-07-26 07:23:32 +00001304- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1305 to recursive calls and call it with the failing package name.
1306
Martin v. Löwis0b483032006-07-25 09:53:12 +00001307- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1308
Georg Brandlc13c34c2006-07-24 14:09:56 +00001309- Patch #1515343: Fix printing of deprecated string exceptions with a
1310 value in the traceback module.
1311
Greg Ward48fae7a2006-07-23 16:05:51 +00001312- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1313
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001314- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1315
Brett Cannoncaebe222006-07-18 04:41:36 +00001316- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1317 argument tuple. For arguments where zero is illegal, the value is forced to
1318 the minimum value that is correct. This is to support an undocumented but
1319 common way people used to fill in inconsequential information in the time
1320 tuple pre-2.4.
1321
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001322- Patch #1220874: Update the binhex module for Mach-O.
1323
Barry Warsawb110bad2006-07-21 14:51:07 +00001324- The email package has improved RFC 2231 support, specifically for
1325 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1326 (name*0=<blah>) parameter continuations. This may change the types of
1327 values returned from email.message.Message.get_param() and friends.
1328 Specifically in some cases where non-encoded continuations were used,
1329 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1330 will just return the string (since non-encoded continuations don't have
1331 charset and language parts).
1332
1333 Also, whereas % values were decoded in all parameter continuations, they are
1334 now only decoded in encoded parameter parts.
1335
Ronald Oussoren3075e162006-07-25 20:28:55 +00001336- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1337
1338- Bug #1517996: IDLE now longer shows the default Tk menu when a
1339 path browser, class browser or debugger is the frontmost window on MacOS X
1340
Barry Warsaw00decd72006-07-27 23:43:15 +00001341- Patch #1520294: Support for getset and member descriptors in types.py,
1342 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1343 of an object against these built-in types and more importantly, for getting
1344 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001347Extension Modules
1348-----------------
1349
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001350- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1351 a socket operation on a socket with a timeout, the exception will be
1352 caught correctly. Previously, the exception was not caught.
1353
Thomas Heller1393d6a2006-07-28 21:43:20 +00001354- Patch #1529514: The _ctypes extension is now compiled on more
1355 openbsd target platforms.
1356
Tim Peters9cab5932006-07-28 00:30:00 +00001357- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1358 a memory leak, affecting pickles and deep copies.
1359
Tim Petersbc24eee2006-07-27 01:14:53 +00001360- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001361 Paul Eggert.
1362
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001363- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1364
Thomas Hellerce049a02006-07-14 17:51:14 +00001365- Patch #1521817: Index range checking on ctypes arrays containing
1366 exactly one element enabled again. This allows iterating over these
1367 arrays, without the need to check the array size before.
1368
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001369- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001370 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001371 /dev/null in certain cases; this is now fixed.
1372
Thomas Heller47d7a062006-07-12 08:43:47 +00001373- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1374 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001375
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001376- Because of a misspelled preprocessor symbol, ctypes was always
1377 compiled without thread support; this is now fixed.
1378
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001379- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1380 methods now allow their database parameter to be None as the
1381 sleepycat API allows.
1382
Matt Flemingec926502006-07-28 11:27:27 +00001383- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1384 bluetooth API compared with Linux and FreeBSD.
1385
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001386Tests
1387-----
1388
1389- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1390 how long the test file should take to play. Now accepts taking 2.93 secs
1391 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1392
Georg Brandl4793aa32006-07-28 18:31:39 +00001393- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1394 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1395 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001402Mac
1403---
1404
1405- PythonLauncher now works correctly when the path to the script contains
1406 characters that are treated specially by the shell (such as quotes).
1407
1408- Bug #1527397: PythonLauncher now launches scripts with the working directory
1409 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001410 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001411 expect.

1420-----------------
1421
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001422- Bug #1441486: The literal representation of -(sys.maxint - 1)
1423 again evaluates to a int object, not a long.
1424
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001425- Bug #1501934: The scope of global variables that are locally assigned
1426 using augmented assignment is now correctly determined.
1427
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001428- Bug #927248: Recursive method-wrapper objects can now safely
1429 be released.
1430
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001431- Bug #1417699: Reject locale-specific decimal point in float()
1432 and atof().
1433
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001434- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1435 omit a default "error" argument for NULL pointer. This allows
1436 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001437
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001438- Bug #1519018: 'as' is now validated properly in import statements.
1439
Neal Norwitz28746ab2006-07-09 22:14:42 +00001440- On 64 bit systems, int literals that use less than 64 bits are
1441 now ints rather than longs.
1442
Neal Norwitzed657552006-07-10 00:04:44 +00001443- Bug #1512814, Fix incorrect lineno's when code at module scope
1444 started after line 256.
1445
Tim Peters32a83612006-07-10 21:08:24 +00001446- New function ``sys._current_frames()`` returns a dict mapping thread
1447 id to topmost thread stack frame. This is for expert use, and is
1448 especially useful for debugging application deadlocks. The functionality
1449 was previously available in Fazal Majid's ``threadframe`` extension
1450 module, but it wasn't possible to do this in a wholly threadsafe way from
1451 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001456- Bug #1257728: Mention Cygwin in distutils error message about a missing
1457 VS 2003.
1458
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001459- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1460
Tim Peters32a83612006-07-10 21:08:24 +00001461- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001462 environment variable to be set in order to the SDK environment
1463 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +00001467- warnings.py now ignores ImportWarning by default
1468
Thomas Woutersadd19112006-07-05 11:03:49 +00001469- string.Template() now correctly handles tuple-values. Previously,
1470 multi-value tuples would raise an exception and single-value tuples would
1471 be treated as the value they contain, instead.
1472
Martin v. Löwisede77f52006-07-03 13:01:35 +00001473- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1474 even if some data are received.
1475
Martin v. Löwis45482392006-07-03 12:28:58 +00001476- Bug #1267547: Put proper recursive setup.py call into the
1477 spec file generated by bdist_rpm.
1478

1480 degrees and radians.
1481
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001482- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001483 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001484
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001485- Bug #1514703: Only setup canvas window in turtle when the canvas
1486 is created.
1487
Martin v. Löwis7596e832006-07-01 15:33:37 +00001488- Bug #1513223: .close() of a _socketobj now releases the underlying
1489 socket again, which then gets closed as it becomes unreferenced.
1490
Fred Drake10497c82006-06-29 02:57:48 +00001491- Bug #1504333: Make sgmllib support angle brackets in quoted
1492 attribute values.
1493
1494- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1495 sgmllib ('[' and ']' were not accepted).
1496

1498
Brett Cannon53ab5b72006-06-22 16:49:14 +00001499- Bug #1510580: The 'warnings' module improperly required that a Warning
1500 category be either a types.ClassType and a subclass of Warning. The proper
1501 check is just that it is a subclass with Warning as the documentation states.
1502
Georg Brandlad29e632006-06-21 17:45:17 +00001503- The compiler module now correctly compiles the new try-except-finally
1504 statement (bug #1509132).
1505
Neal Norwitz60373cd2006-06-22 06:30:50 +00001506- The wsgiref package is now installed properly on Unix.
1507

1509 shutdown when fileConfig() was called multiple times.
1510
Gerhard Häring762fbd32006-07-02 17:48:30 +00001511- The sqlite3 module did cut off data from the SQLite database at the first
1512 null character before sending it to a custom converter. This has been fixed
1513 now.
1514
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001515Extension Modules
1516-----------------
1517
Tim Peters112aad32006-07-19 00:03:19 +00001518- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1519 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1520 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001521
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001522- Assigning None to pointer type fields in ctypes structures possible
1523 overwrote the wrong fields, this is fixed now.
1524
1525- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1526 on non-Windows platforms.
1527
1528- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1529 integer or long, without range checking.
1530
1531- Patch #1517790: It is now possible to use custom objects in the ctypes
1532 foreign function argtypes sequence as long as they provide a from_param
1533 method, no longer is it required that the object is a ctypes type.
1534
1535- The '_ctypes' extension module now works when Python is configured
1536 with the --without-threads option.
1537
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001538- Bug #1513646: os.access on Windows now correctly determines write
1539 access, again.
1540
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001541- Bug #1512695: cPickle.loads could crash if it was interrupted with
1542 a KeyboardInterrupt.
1543

Martin v. Löwisd73168d2006-07-14 09:58:55 +00001552- Automate Windows build process for the Win64 SSL module.
1553
Tim Peters32a83612006-07-10 21:08:24 +00001554- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001555 Previously, the slight difference could cause compilation errors of the
1556 'zlib' module on systems with more than one version of zlib.
1557
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001558- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001588
1589Core and builtins
1590-----------------
1591
Georg Brandla56b9152006-06-19 06:35:54 +00001592- Patch #1507676: Error messages returned by invalid abstract object operations
1593 (such as iterating over an integer) have been improved and now include the
1594 type of the offending object to help with debugging.
1595
Brett Cannonea3912b2006-06-13 21:46:41 +00001596- Bug #992017: A classic class that defined a __coerce__() method that returned
1597 its arguments swapped would infinitely recurse and segfault the interpreter.
1598
Neal Norwitz909eb122006-06-12 02:13:21 +00001599- Fix the socket tests so they can be run concurrently.
1600
Neal Norwitzb9845e72006-06-12 02:11:18 +00001601- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001602 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001603
Brett Cannon22565aa2006-06-09 22:31:23 +00001604- Bug #532646: object.__call__() will continue looking for the __call__
1605 attribute on objects until one without one is found. This leads to recursion
1606 when you take a class and set its __call__ attribute to an instance of the
1607 class. Originally fixed for classic classes, but this fix is for new-style.
1608 Removes the infinite_rec_3 crasher.
1609
Georg Brandl24250812006-06-09 18:45:48 +00001610- The string and unicode methods startswith() and endswith() now accept
1611 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1612
Brett Cannonde3b0522006-06-08 17:00:45 +00001613- Buffer objects, at the C level, never used the char buffer
1614 implementation even when the char buffer for the wrapped object was
1615 explicitly requested (originally returned the read or write buffer).
1616 Now a TypeError is raised if the char buffer is not present but is
1617 requested.
1618
Georg Brandlddbaa662006-06-04 21:56:52 +00001619- Patch #1346214: Statements like "if 0: suite" are now again optimized
1620 away like they were in Python 2.4.
1621
Georg Brandlb7c8f542006-05-27 12:30:25 +00001622- Builtin exceptions are now full-blown new-style classes instead of
1623 instances pretending to be classes, which speeds up exception handling
1624 by about 80% in comparison to 2.5a2.
1625
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001626- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1627 Unicode 4.1.
1628
Georg Brandlf4ef1162006-05-26 18:03:31 +00001629- Patch #921466: sys.path_importer_cache is now used to cache valid and
1630 invalid file paths for the built-in import machinery which leads to
1631 fewer open calls on startup.
1632
Tim Peters696cf432006-05-24 21:10:40 +00001633- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1634 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1635 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1636 the number of input digits (it was and remains linear-time for bases
1637 2, 4, 8, 16 and 32).
1638
Tim Petersb713ec22006-05-23 18:45:30 +00001639- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1640 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1641 an integer close to ``sys.maxint``. This was repaired by patch
1642 #1335972, which also gives a nice speedup.
1643
Richard Jonescebbefc2006-05-23 18:28:17 +00001644- Patch #1337051: reduced size of frame objects.
1645
1646- PyErr_NewException now accepts a tuple of base classes as its
1647 "base" parameter.
1648
Richard Jones7c88dcc2006-05-23 10:37:38 +00001649- Patch #876206: function call speedup by retaining allocated frame
1650 objects.
1651
Georg Brandl7b90e162006-05-18 07:01:27 +00001652- Bug #1462152: file() now checks more thoroughly for invalid mode
1653 strings and removes a possible "U" before passing the mode to the
1654 C library function.
1655
Neal Norwitz1004a532006-05-15 07:17:23 +00001656- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1657
Neal Norwitz373f0a72006-05-15 07:04:36 +00001658- Bug #1487966: Fix SystemError with conditional expression in assignment
1659
Martin v. Löwis879768d2006-05-11 13:28:43 +00001660- WindowsError now has two error code attributes: errno, which carries
1661 the error values from errno.h, and winerror, which carries the error
1662 values from winerror.h. Previous versions put the winerror.h values
1663 (from GetLastError()) into the errno attribute.
1664
Martin v. Löwis77736712006-05-04 05:51:03 +00001665- Patch #1475845: Raise IndentationError for unexpected indent.
1666
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001667- Patch #1479181: split open() and file() from being aliases for each other.
1668
Tim Peters44bd9862006-06-01 13:49:23 +00001669- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1670 methods were always silently ignored by dictionaries when comparing keys.
1671 They are now passed through (except when using the C API function
1672 ``PyDict_GetItem()``, whose semantics did not change).
1673
1674- Bug #1456209: In some obscure cases it was possible for a class with a
1675 custom ``__eq__()`` method to confuse dict internals when class instances
1676 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1677 No, you don't have any code that did this ;-)

1685
Brett Cannon6ee7d012006-06-08 16:23:04 +00001686- Change binascii.hexlify to accept a read-only buffer instead of only a char
1687 buffer and actually follow its documentation.
1688

1690
Nick Coghlanc649ec52006-05-29 12:43:05 +00001691- Patch #1478788 (modified version): The functional extension module has
1692 been renamed to _functools and a functools Python wrapper module added.
1693 This provides a home for additional function related utilities that are
1694 not specifically about functional programming. See PEP 309.
1695
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001696- Patch #1493701: performance enhancements for struct module.

1704 enabled builds on Windows and systems with Posix threads support.
1705
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001706- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1707 (up to the system limit of 32K characters).
1708
1709- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1710 As a result, these functions now raise WindowsError instead of OSError.
1711
Tim Peters7a822da2006-05-25 21:50:17 +00001712- ``time.clock()`` on Win64 should use the high-performance Windows
1713 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1714 Windows platforms).
1715
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001716- Calling Tk_Init twice is refused if the first call failed as that
1717 may deadlock.
1718
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001719- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1720 accept it without potentially using an uninitialized pointer.
1721
1722- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1723 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1733 results. It could previously incorrectly return 0 in some cases.
1734 Fixes SF bug 1493322 (pybsddb bug 1184012).
1735
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001736- bsddb: the bsddb.dbtables Modify method now raises the proper error and

1738 Fixes SF python patch/bug #1408584.
1739
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001740- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001741 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001742 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1743 database calls that would previously deadlock. [SF python bug #775414]

Georg Brandl83cc0d02006-06-14 08:50:03 +00001766- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1767 mime.types file for determining MIME types.
1768
Georg Brandl2605ca82006-06-14 06:08:31 +00001769- Bug #1339007: Shelf objects now don't raise an exception in their
1770 __del__ method when initialization failed.
1771
Martin v. Löwisd8251432006-06-14 05:21:04 +00001772- Patch #1455898: The MBCS codec now supports the incremental mode for
1773 double-byte encodings.
1774
Tim Peters43898b42006-06-14 04:09:25 +00001775- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1776 guarantee that adjacent triples in the return list always describe
1777 non-adjacent blocks. Previously, a pair of matching blocks could end
1778 up being described by multiple adjacent triples that formed a partition
1779 of the matching pair.
1780
Greg Ward0e0c9f42006-06-11 16:24:11 +00001781- Bug #1498146: fix optparse to handle Unicode strings in option help,
1782 description, and epilog.
1783
Greg Wardd1c797e2006-06-11 14:42:41 +00001784- Bug #1366250: minor optparse documentation error.
1785
Greg Ward7f547402006-06-11 00:40:49 +00001786- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1787 clarify docs.
1788
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001789- The wsgiref package has been added to the standard library.
1790
Nick Coghlan676725d2006-06-08 13:54:49 +00001791- The functions update_wrapper() and wraps() have been added to the functools
1792 module. These make it easier to copy relevant metadata from the original
1793 function when writing wrapper functions.
1794
Tim Petersd6a9eef2006-06-05 01:48:21 +00001795- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1796 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001797
Martin v. Löwis3f767792006-06-04 19:36:28 +00001798- Patch #1359618: Speed up charmap encoder by using a trie structure
1799 for lookup.
1800
Tim Petersd609b1a2006-06-02 23:22:51 +00001801- The functions in the ``pprint`` module now sort dictionaries by key
1802 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1803 if and only if its display required more than one line, although that
1804 wasn't documented. The new behavior increases predictability; e.g.,
1805 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1806
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001807- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1808 (thanks for J. J. Lee).
1809
Georg Brandl2b330372006-05-28 20:23:12 +00001810- Patch #1496206: improve urllib2 handling of passwords with respect to
1811 default HTTP and HTTPS ports.
1812
George Yoshidaf3c65de2006-05-28 16:39:09 +00001813- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1814
Bob Ippolito7298f272006-05-23 18:43:47 +00001815- Patch #1281707: speed up gzip.readline.
1816
Georg Brandlb89316f2006-05-17 15:51:16 +00001817- Patch #1180296: Two new functions were added to the locale module:
1818 format_string() to get the effect of "format % items" but locale-aware,
1819 and currency() to format a monetary number with currency sign.
1820
Georg Brandle3a25832006-05-17 14:56:04 +00001821- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1822 and several features added, such as speed and geometry control.
1823
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001824- Patch #1488881: add support for external file objects in bz2 compressed
1825 tarfiles.
1826
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001827- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1828 stdout arguments, making it possible to redirect input and output
1829 for remote debugging.
1830
1831- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1832 a couple of issues, notably handling of long file names using the
1833 GNU LONGNAME extension.
1834
1835- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1836 new flag when ``name`` is already the name of an option flag.
1837
1838- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1839 package.
1840
1841- Patch #1472854: make the rlcompleter.Completer class usable on non-
1842 UNIX platforms.
1843
1844- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1845
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001846- Bug #1472827: correctly escape newlines and tabs in attribute values in
1847 the saxutils.XMLGenerator class.

1856
Martin v. Löwisa43190b2006-05-22 09:15:18 +00001857- Patch #1492356: Port to Windows CE.
1858
Neal Norwitz58e28882006-05-19 07:00:58 +00001859- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001877What's New in Python 2.5 alpha 2?
1878=================================
1879
1880*Release date: 27-APR-2006*
1881
1882Core and builtins
1883-----------------
1884
Thomas Heller1b046642006-04-18 18:51:06 +00001885- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1886 by converting these apis from macros into exported functions again:
1887
1888 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1889 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1890 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1891 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1892 PyRun_String Py_CompileString
1893
Martin v. Löwis45294a92006-04-18 06:24:08 +00001894- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1895
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001896- All uses of PyStructSequence_InitType have been changed to initialize
1897 the type objects only once, even if the interpreter is initialized
1898 multiple times.
1899
Neal Norwitz61546162006-04-14 05:20:28 +00001900- Bug #1454485, array.array('u') could crash the interpreter. This was
1901 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1902 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1903
1904- Py_UNICODE is unsigned. It was always documented as unsigned, but
1905 due to a bug had a signed value in previous versions.
1906
Tim Peters3a5e8b12006-04-11 01:44:07 +00001907- Patch #837242: ``id()`` of any Python object always gives a positive
1908 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1909 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001910 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001911 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001912
Tim Peters3a5e8b12006-04-11 01:44:07 +00001913 def __hash__(self):
1914 return id(self) # WRONG
1915
1916 because a hash result must be a (short) Python int but it was always
1917 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001918 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001919 was always usable as a hash value before this patch. That's no longer
1920 necessarily so.
1921
1922- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001923 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001924 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001925 #1454844)
1926
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001927- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1928 involving generators that have paused outside of any ``try`` or ``with``
1929 blocks. (In 2.5a1, a paused generator that was part of a reference
1930 cycle could not be garbage collected, regardless of whether it was
1931 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001932
Anthony Baxter51bcb682006-04-05 14:51:42 +00001933Extension Modules

1938
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001939- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1940 fails with an error condition.
1941
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001942- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1943
1944- Bug #1117761: bsddb.*open() no longer raises an exception when using
1945 the cachesize parameter.
1946
1947- Bug #1149413: bsddb.*open() no longer raises an exception when using
1948 a temporary db (file=None) with the 'n' flag to truncate on open.
1949
1950- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1951 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001952
Armin Rigoa9017c32006-04-19 11:50:27 +00001953- Patch #1062014: AF_UNIX sockets under Linux have a special
1954 abstract namespace that is now fully supported.

1958
Peter Astrand7d1d4362006-07-14 14:04:45 +00001959- Bug #1223937: subprocess.CalledProcessError reports the exit status
1960 of the process using the returncode attribute, instead of
1961 abusing errno.
1962
Tim Peters711bf302006-04-25 03:31:36 +00001963- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1964 a doctest to be skipped (the code is not run, and the expected output
1965 or exception is ignored).
1966
Nick Coghlanda2268f2006-04-24 04:37:15 +00001967- Fixed contextlib.nested to cope with exceptions being raised and
1968 caught inside exit handlers.
1969
Greg Wardab05edc2006-04-23 03:47:58 +00001970- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1971 hex, octal, or binary; add ``append_const`` action; keep going if
1972 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1973 added ``epilog`` for better help generation).
1974
Tim Peters21fbd572006-04-21 21:18:10 +00001975- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1976 called from a thread spawned as a side effect of importing a module.
1977
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001978- The pydoc module now supports documenting packages contained in
1979 .zip or .egg files.
1980
1981- The pkgutil module now has several new utility functions, such
1982 as ``walk_packages()`` to support working with packages that are either
1983 in the filesystem or zip files.
1984
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001985- The mailbox module can now modify and delete messages from
1986 mailboxes, in addition to simply reading them. Thanks to Gregory
1987 K. Johnson for writing the code, and to the 2005 Google Summer of
1988 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001989
Tim Petersc7605f22006-04-17 21:12:33 +00001990- The ``__del__`` method of class ``local`` in module ``_threading_local``
1991 returned before accomplishing any of its intended cleanup.
1992
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001993- Patch #790710: Add breakpoint command lists in pdb.

1998
Anthony Baxtere29002c2006-04-12 12:07:31 +00001999- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2000 Windows. Bug #1469163.
2001
Phillip J. Eby47032112006-04-11 01:07:43 +00002002- The warnings, linecache, inspect, traceback, site, and doctest modules
2003 were updated to work correctly with modules imported from zipfiles or
2004 via other PEP 302 __loader__ objects.
2005
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002006- Patch #1467770: Reduce usage of subprocess._active to processes which

2018
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002019- The Makefile now has a reindent target, which runs reindent.py on
2020 the library.
2021

2027 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002028 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002029 CXX from --with-cxx-main, see description in README.
2030

2034
Tim Peters8931ff12006-05-13 23:28:20 +00002035- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2036 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

2038
Anthony Baxter51bcb682006-04-05 14:51:42 +00002039Tests
2040-----
2041
Nick Coghlanda2268f2006-04-24 04:37:15 +00002042- test_contextlib now checks contextlib.nested can cope with exceptions
2043 being raised and caught inside exit handlers.
2044
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002045- test_cmd_line now checks operation of the -m and -c command switches
2046
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002047- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2048 it separately and by hand. It also wasn't cleaning up its changes to
2049 the current Decimal context.
2050
Thomas Woutersabd08882006-04-26 15:53:30 +00002051- regrtest.py now has a -M option to run tests that test the new limits of
2052 containers, on 64-bit architectures. Running these tests is only sensible
2053 on 64-bit machines with more than two gigabytes of memory. The argument
2054 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002080Core and builtins
2081-----------------
2082
Nick Coghlan43832302006-04-23 17:04:07 +00002083- PEP 338: -m command line switch now delegates to runpy.run_module
2084 allowing it to support modules in packages and zipfiles
2085
Martin v. Löwisc661b882006-04-20 04:54:23 +00002086- On Windows, .DLL is not an accepted file name extension for
2087 extension modules anymore; extensions are only found if they
2088 end in .PYD.
2089
Martin v. Löwisea62d252006-04-03 10:56:49 +00002090- Bug #1421664: sys.stderr.encoding is now set to the same value as
2091 sys.stdout.encoding.
2092
Neal Norwitz92e212f2006-04-03 04:48:37 +00002093- __import__ accepts keyword arguments.
2094
Georg Brandlccadf842006-03-31 18:54:53 +00002095- Patch #1460496: round() now accepts keyword arguments.
2096
Anthony Baxter262c00a2006-03-30 10:53:17 +00002097- Fixed bug #1459029 - unicode reprs were double-escaped.
2098
Hye-Shik Changd478f342006-03-23 12:32:36 +00002099- Patch #1396919: The system scope threads are reenabled on FreeBSD
2100 5.4 and later versions.
2101
Neal Norwitze98ccf62006-03-23 05:39:47 +00002102- Bug #1115379: Compiling a Unicode string with an encoding declaration
2103 now gives a SyntaxError.
2104
Georg Brandlabd1ff82006-03-18 07:59:59 +00002105- Previously, Python code had no easy way to access the contents of a
2106 cell object. Now, a ``cell_contents`` attribute has been added
2107 (closes patch #1170323).
2108
Tim Peterscf79aac2006-03-16 01:14:46 +00002109- Patch #1123430: Python's small-object allocator now returns an arena to
2110 the system ``free()`` when all memory within an arena becomes unused
2111 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2112 freed. Some applications will see a drop in virtual memory size now,
2113 especially long-running applications that, from time to time, temporarily
2114 use a large number of small objects. Note that when Python returns an
2115 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002116 platform C library will in turn return that memory to the operating system.
2117 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002118 appears to be effective at least on Microsoft C and gcc-based systems.
2119 Thanks to Evan Jones for hard work and patience.
2120
Georg Brandl533ff6f2006-03-08 18:09:27 +00002121- Patch #1434038: property() now uses the getter's docstring if there is
2122 no "doc" argument given. This makes it possible to legitimately use
2123 property() as a decorator to produce a read-only property.
2124
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002125- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2126 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2127 of requiring an int or long in slicing and a few other contexts, enabling
2128 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2129
Neal Norwitz995acdf2006-03-07 05:01:00 +00002130- Fixed various bugs reported by Coverity's Prevent tool.
2131
Brett Cannonbf364092006-03-01 04:25:17 +00002132- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2133 new exception base class, BaseException, which has a new message attribute.
2134 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2135 Raising a string exception now raises a DeprecationWarning.
2136
Thomas Woutersfb609f42006-02-28 16:37:25 +00002137- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2138 explicitly relative, using 'from .module import name' to mean 'from the same
2139 package as this module is in. Imports without dots still default to the
2140 old relative-then-absolute, unless 'from __future__ import
2141 absolute_import' is used.
2142
Brett Cannona7446e32006-02-27 23:39:10 +00002143- Properly check if 'warnings' raises an exception (usually when a filter set
2144 to "error" is triggered) when raising a warning for raising string
2145 exceptions.
2146
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002147- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002148 The name was removed from Include/code.h.
2149
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002150- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002151
Guido van Rossum1968ad32006-02-25 22:38:04 +00002152- Patch 1433928:
2153 - The copy module now "copies" function objects (as atomic objects).
2154 - dict.__getitem__ now looks for a __missing__ hook before raising
2155 KeyError.
2156
Tim Peters84ef21c2006-02-28 20:39:06 +00002157- PEP 343: with statement implemented. Needs ``from __future__ import
2158 with_statement``. Use of 'with' as a variable will generate a warning.
2159 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002160 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002161 The following objects have __context__ methods:
2162 - The built-in file type.
2163 - The thread.LockType type.
2164 - The following types defined by the threading module:
2165 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2166 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002167
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002168- Fix the encodings package codec search function to only search
2169 inside its own package. Fixes problem reported in patch #1433198.
2170
2171 Note: Codec packages should implement and register their own
2172 codec search function. PEP 100 has the details.
2173
Tim Peters9ea89d22006-06-04 03:26:02 +00002174- PEP 353: Using ``Py_ssize_t`` as the index type.
2175
2176- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2177 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2178 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2179 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2180 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002181
Neal Norwitzfc76d632006-01-10 06:03:13 +00002182- Patch #1400181, fix unicode string formatting to not use the locale.
2183 This is how string objects work. u'%f' could use , instead of .
2184 for the decimal point. Now both strings and unicode always use periods.
2185
Neal Norwitz671b9e32006-01-09 07:07:12 +00002186- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2187 configure would break checking curses.h.
2188
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002189- Bug #959576: The pwd module is now builtin. This allows Python to be
2190 built on UNIX platforms without $HOME set.
2191
Neal Norwitzc10978f2005-12-19 06:07:16 +00002192- Bug #1072182, fix some potential problems if characters are signed.
2193
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002194- Bug #889500, fix line number on SyntaxWarning for global declarations.
2195
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002196- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2197
Neal Norwitze7214a12005-12-18 05:03:17 +00002198- Support for converting hex strings to floats no longer works.
2199 This was not portable. float('0x3') now raises a ValueError.
2200
Barry Warsaw2a38a862005-12-18 01:27:35 +00002201- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002202 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002203 is now displayed in interactive prompt banner.
2204
Georg Brandlfa166682005-12-17 21:45:17 +00002205- Implementation of PEP 341 - Unification of try/except and try/finally.
2206 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002207 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002208
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002209- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2210 now encodes backslash correctly.
2211
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002212- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2213
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002214- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002215 and long longs.
2216
Neal Norwitz67715f02005-11-09 06:59:35 +00002217- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002218 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002219 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002220
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002221- Replaced most Unicode charmap codecs with new ones using the
2222 new Unicode translate string feature in the builtin charmap
2223 codec; the codecs were created from the mapping tables available
2224 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2225 encodings now include a mapping for the Apple logo)
2226
Tim Peterse3547fd2005-12-16 23:13:57 +00002227- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002228
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002229- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002230
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002231- A new AST parser implementation was completed. The abstract
2232 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002233 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002234
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002235- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002236 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2237
Neal Norwitz708e51a2005-10-03 04:48:15 +00002238- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2239
Neal Norwitz11bd1192005-10-03 00:54:56 +00002240- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2241 Provide a warning when a directory is passed on the command line.
2242
Neal Norwitz40d37812005-10-02 01:48:49 +00002243- Fix segfault with invalid coding.
2244
2245- SF bug #772896: unknown encoding results in MemoryError.
2246
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002247- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002248 supported a __len__() method which evaluated to False when the iterator
2249 was empty.
2250
Guido van Rossum630db602005-09-20 18:49:54 +00002251- On 64-bit platforms, when __len__() returns a value that cannot be
2252 represented as a C int, raise OverflowError.
2253
Skip Montanarof8948ca2005-09-19 03:54:46 +00002254- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002255 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002256
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002257- SF bug #893549: parsing keyword arguments was broken with a few format
2258 codes.
2259
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002260- Changes donated by Elemental Security to make it work on AIX 5.3
2261 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2262 bug #105470: test_pwd fails on 64bit system (Opteron).
2263
Guido van Rossum539c6622005-09-14 17:49:54 +00002264- Changes donated by Elemental Security to make it work on HP-UX 11 on
2265 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2266
Georg Brandl4550b8d2005-08-26 06:43:52 +00002267- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002268 (fixes bug #1119418).
2269
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002270- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2271
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002272- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2273 exceptions that cause a function to exit.
2274
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002275- The implementation of set() and frozenset() was revised to use its
2276 own internal data structure. Memory consumption is reduced by 1/3
2277 and there are modest speed-ups as well. The API is unchanged.
2278
Tim Petersde7990b2005-07-17 23:45:23 +00002279- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2280
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002281- SF bug #1229429: PyObject_CallMethod failed to decrement some
2282 reference counts in some error exit cases.
2283
Tim Petersecc6e6a2005-07-10 22:30:55 +00002284- SF bug #1185883: Python's small-object memory allocator took over
2285 a block managed by the platform C library whenever a realloc specified
2286 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002287 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002288 portable way to copy data from the C-managed block into Python's
2289 small-object space without risking a memory fault. Python's small-object
2290 realloc now leaves such blocks under the control of the platform C
2291 realloc.
2292
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002293- SF bug #1232517: An overflow error was not detected properly when
2294 attempting to convert a large float to an int in os.utime().
2295
Raymond Hettinger3296e692005-06-29 23:29:56 +00002296- SF bug #1224347: hex longs now print with lowercase letters just
2297 like their int counterparts.
2298
Michael W. Hudson188d4362005-06-20 16:52:57 +00002299- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2300 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2301 interpreter states; back out that fix and do a better job (see
2302 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2303 for a longer write-up of the problem).
2304
Michael W. Hudsondf888462005-06-03 14:41:55 +00002305- SF patch #1180995: marshal now uses a binary format by default when
2306 serializing floats.
2307
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002308- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2309 the routines that promise to produce IEEE 754 binary representations
2310 of floats now simply copy bytes around.
2311
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002312- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2313 278.
2314
Brett Cannonc3647ac2005-04-26 03:45:26 +00002315- patch #1109424: int, long, float, complex, and unicode now check for the
2316 proper magic slot for type conversions when subclassed. Previously the
2317 magic slot was ignored during conversion. Semantics now match the way
2318 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002319 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002320 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002321 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002322
Barry Warsawc8d907c2005-04-19 23:43:40 +00002323- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2324 NULL, now raise an AttributeError when attempting to set or delete the
2325 attribute. Previously a TypeError was raised, but this was inconsistent
2326 with the equivalent pure-Python implementation.
2327
Michael W. Hudson774479c2005-04-18 08:46:17 +00002328- It is now safe to call PyGILState_Release() before
2329 PyEval_InitThreads() (note that if there is reason to believe there
2330 are multiple threads around you still must call PyEval_InitThreads()
2331 before using the Python API; this fix is for extension modules that
2332 have no way of knowing if Python is multi-threaded yet).
2333
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002334- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2335 disabled caused a crash.
2336
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002337- Bug #1165306: instancemethod_new allowed the creation of a method
2338 with im_class == im_self == NULL, which caused a crash when called.
2339
Tim Petersecc6e6a2005-07-10 22:30:55 +00002340- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002341 fixes the crash seen in bug #1165761
2342

Jeremy Hyltonab630502005-02-04 18:44:06 +00002377- The parser did not complain about future statements in illegal

2383 calling __str__ on the argument returns a unicode instance.
2384
Tim Petersf4e69282006-02-27 17:15:31 +00002385- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2386 current thread state when the auto-GIL-state machinery knows about
2387 it (since the thread state is being deleted, continuing to remember it
2388 can't help, but can hurt if another thread happens to get created with
2389 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00002585- PEP 338: new module runpy defines a run_module function to support
2586 executing modules which provide access to source code or a code object
2587 via the PEP 302 import mechanisms.

2597 in attribute values.
2598
Anthony Baxterc51ee692006-04-01 00:57:31 +00002599- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002600 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002601 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002602 module will not be built.
2603
Tim Petersc17976e2006-04-01 00:26:53 +00002604- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2605 aren't officially supported here, and trying to use them will probably
2606 raise an exception some day. But dicts have been allowed, and "mostly

2627
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002628- email 4.0 package now integrated. This is largely the same as the email 3.0
2629 package that was included in Python 2.3, except that PEP 8 module names are
2630 now used (e.g. mail.message instead of email.Message). The MIME classes
2631 have been moved to a subpackage (e.g. email.mime.text instead of
2632 email.MIMEText). The old names are still supported for now. Several
2633 deprecated Message methods have been removed and lots of bugs have been
2634 fixed. More details can be found in the email package documentation.

2637 (a subclass of tuple) that provides incremental decoders and encoders
2638 (a way to use stateful codecs without the stream API). Python functions
2639 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2640 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2641 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002642

2644 a ValueError instead of a StopIteration now (like file and cString.String do).
2645 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2646 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002720 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2721 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2722 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2723 Ronald L. Rivest offered this advice for Python:
2724
2725 "The consensus of researchers in this area (at least as
2726 expressed at the NIST Hash Function Workshop 10/31/05),
2727 is that SHA-256 is a good choice for the time being, but
2728 that research should continue, and other alternatives may
2729 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002730
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002731- Added a subset of Fredrik Lundh's ElementTree package. Available

2887
Raymond Hettingerbab41432005-02-05 01:31:19 +00002888- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2889
Guido van Rossumd0641422005-02-03 15:01:24 +00002890- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2891 disables recursive traversal through instance attributes, which can
2892 be exploited in various ways.
2893
Tim Peterse3547fd2005-12-16 23:13:57 +00002894- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002895 flags on the HTTP listening socket.
2896
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002897- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2898 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2899
Fred Drakefbdeaad2006-07-29 16:56:15 +00002900- Patches #893642, #1039083: add allow_none, encoding arguments to
2901 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002902

2906
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002907- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2908
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002909- Enhancements to the csv module:
2910
2911 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002912 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002913 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002914 + Dialect parameter parsing has been re-implemented to improve error
2915 reporting.
2916 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2917 dictates.
2918 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002919 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002920 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002921 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2922 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002923 + reader now allows \r characters to be quoted (previously it only allowed
2924 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002925 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002926 + Dialect classes passed to the module are no longer instantiated by
2927 the module before being parsed (the former validation scheme required
2928 this, but the mechanism was unreliable).
2929 + The dialect registry now contains instances of the internal
2930 C-coded dialect type, rather than references to python objects.
2931 + the internal c-coded dialect type is now immutable.
2932 + register_dialect now accepts the same keyword dialect specifications
2933 as the reader and writer, allowing the user to register dialects
2934 without first creating a dialect class.
2935 + a configurable limit to the size of parsed fields has been added -
2936 previously, an unmatched quote character could result in the entire
2937 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002938 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002939 the parser field size limit (returning the former limit). The initial
2940 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002941 + A line_num attribute has been added to the reader object, which tracks
2942 the number of lines read from the source iterator. This is not
2943 the same as the number of records returned, as records can span
2944 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002945 + reader and writer objects were not being registered with the cyclic-GC.
2946 This has been fixed.
2947
Brett Cannone6539c42005-01-08 02:43:53 +00002948- _DummyThread objects in the threading module now delete self.__block that is
2949 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2950 lock primitives tend to be limited in number and thus should not be wasted on
2951 a _DummyThread object. Fixes bug #1089632.
2952
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002953- The imghdr module now detects Exif files.
2954
Raymond Hettinger6065d322004-12-20 23:51:53 +00002955- StringIO.truncate() now correctly adjusts the size attribute.
2956 (Bug #951915).
2957
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002958- locale.py now uses an updated locale alias table (built using
2959 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2960 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002961 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002962
Raymond Hettinger3557f422004-12-07 12:02:02 +00002963- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2964
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002965- the pickle module no longer accepts the deprecated None option in the
2966 args tuple returned by __reduce__().
2967
Brett Cannon84667c02004-12-07 03:25:18 +00002968- optparse now optionally imports gettext. This allows its use in setup.py.
2969
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002970- the pickle module no longer uses the deprecated bin parameter.
2971
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002972- the shelve module no longer uses the deprecated binary parameter.
2973
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002974- the pstats module no longer uses the deprecated ignore() method.
2975
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002976- the filecmp module no longer uses the deprecated use_statcache argument.
2977
Raymond Hettinger664347b2004-12-04 21:21:53 +00002978- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2979 extended or overridden by subclasses. Formerly, the subclassed method would
2980 be ignored by the rest of the module. (Bug #1078905).
2981
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002982- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002983 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002984
Walter Dörwald36733692004-12-22 12:50:50 +00002985- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2986 once when a size argument is given. This prevents a buffer overflow in the
2987 tokenizer with very long source lines.
2988
Barry Warsaw538561e2006-01-01 21:48:54 +00002989- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2990 immediately after creating the object, without any intervening
2991 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002992
Skip Montanaro05885812005-01-16 20:48:27 +00002993- The reconvert.quote function can now emit triple-quoted strings. The
2994 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002995
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002996- ``UserString.MutableString`` now supports negative indices in
2997 ``__setitem__`` and ``__delitem__``
2998
Greg Ward40407942005-03-05 02:53:17 +00002999- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3000 correctly.
3001
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003002- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3003 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3004 character even if the user has passed a size parameter to get a proper
3005 line ending. Remove the special handling of a "\r\n" that has been split
3006 between two lines.
3007
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003008- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3009 about illegal code points. The codec now supports PEP 293 style error
3010 handlers.
3011
Walter Dörwald78a78b02005-09-01 12:04:29 +00003012- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003013 from the input stream, so that the output is a byte string in the correct
3014 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003015
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003016- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3017 considering it exactly like a '*'.
3018
Walter Dörwald007f8df2005-10-09 19:42:27 +00003019- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3020 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003021
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003022- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3023
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003024- Patch #1413711: Certain patterns of differences were making difflib
3025 touch the recursion limit.
3026
Walter Dörwald58917a62006-03-31 15:26:22 +00003027- Bug #947906: An object oriented interface has been added to the calendar
3028 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003029 called as a script (e.g. via ``python -mcalendar``). Localized month and
3030 weekday names can be ouput (even if an exotic encoding is used) using
3031 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003032
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003033Build
3034-----
3035
Neal Norwitz602d3392006-03-31 08:21:40 +00003036- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3037 by using -mieee gcc option.
3038

3040
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003041- Build support for Win64-AMD64 was added.
3042
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003043- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3044
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003045- Patch #881820: look for openpty and forkpty also in libbsd.
3046
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003047- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3048 The zlib module is now builtin on Windows.
3049
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003050- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3051
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003052- Bug #1189330: configure did not correctly determine the necessary
3053 value of LINKCC if python was built with GCC 4.0.
3054
Trent Mick8321b422005-07-26 02:29:21 +00003055- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3056 vulnerability in zlib 1.2.1 and 1.2.2.
3057
Brett Cannon08cd5982005-04-24 22:26:38 +00003058- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3059 flags that change binary compatibility. Changes were also made to
3060 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003061 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003062
Bob Ippolitoed233462005-03-29 13:47:59 +00003063- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3064 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3065 no longer exists). This configure patch makes things right.
3066
Martin v. Löwise2713be2005-03-08 15:03:08 +00003067- Bug #1158607: Build with --disable-unicode again.
3068
Brett Cannon46d96232005-02-16 00:07:19 +00003069- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3070 defined. Discovered as a result of not being able to build on OS X.
3071
Brett Cannon516592f2004-12-07 00:42:59 +00003072- setup.py now uses the directories specified in LDFLAGS using the -L option
3073 and in CPPFLAGS using the -I option for adding library and include
3074 directories, respectively, for compiling extension modules against. This has
3075 led to the core being compiled using the values in CPPFLAGS. It also removes
3076 the need for the special-casing of both DarwinPorts and Fink for darwin since
3077 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3078 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3079 Fink, ``-I/opt/local/include`` for DarwinPorts).
3080
Brett Cannon43802422005-02-10 20:48:03 +00003081- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3082 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3083 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3084 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003086C API
3087-----
3088
Tim Petersc9d78aa2006-03-26 23:27:58 +00003089- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3090 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3091 is obtained via the ``PyObject_`` family, it must be released via the
3092 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3093 always been officially true, but when Python's small-object allocator was
3094 introduced, an attempt was made to cater to a few extension modules
3095 discovered at the time that obtained memory via ``PyObject_New`` but
3096 released it via ``PyMem_DEL``. It's years later, and if such code still
3097 exists it will fail now (probably with segfaults, but calling wrong
3098 low-level memory management functions can yield many symptoms).
3099
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003100- Added a C API for set and frozenset objects.
3101
Raymond Hettinger66517482004-12-03 11:45:13 +00003102- Removed PyRange_New().
3103
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003104- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3105 mapping argument now. This string is used as a mapping table. Byte values
3106 greater than the length of the string and 0xFFFE are treated as undefined
3107 mappings.
