Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000906- The return tuple from str.rpartition(sep) is (tail, sep, head) where
907 head is the original string if sep was not found.
908
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000909- Bug #1520864: unpacking singleton tuples in list comprehensions and
910 generator expressions (x for x, in ... ) works again. Fixing this problem
911 required changing the .pyc magic number. This means that .pyc files
912 generated before 2.5c2 will be regenerated.

1024Core and builtins
1025-----------------
1026
Neal Norwitz24b6f202006-09-05 04:43:56 +00001027- Fix infinite recursion when subclassing long and overriding __hash__.
1028
1029- Fix concatenation (+=) of long strings.
1030
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001031- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001032 compared equal or unequal to a string and a UnicodeDecodeError
1033 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001034
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001035 Instead, the equal (==) and unequal (!=) comparison operators will
1036 now issue a UnicodeWarning and interpret the two objects as
1037 unequal. The UnicodeWarning can be filtered as desired using
1038 the warning framework, e.g. silenced completely, turned into an
1039 exception, logged, etc.
1040
1041 Note that compare operators other than equal and unequal will still
1042 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001043
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001044- Fix segfault when doing string formatting on subclasses of long.
1045
1046- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1047 with new-style classes.
1048
1049- Fix bug related to __len__ functions returning negative values with
1050 classic classes.
1051
1052- Patch #1538606, Fix __index__() clipping. There were some problems
1053 discovered with the API and how integers that didn't fit into Py_ssize_t
1054 were handled. This patch attempts to provide enough alternatives
1055 to effectively use __index__.
1056
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001057- Bug #1536021: __hash__ may now return long int; the final hash
1058 value is obtained by invoking hash on the long int.
1059
Thomas Hellerab1049c2006-08-08 17:37:00 +00001060- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1061
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001062- Bug #1535165: fixed a segfault in input() and raw_input() when
1063 sys.stdin is closed.
1064
Thomas Heller74d36f02006-08-04 18:17:40 +00001065- On Windows, the PyErr_Warn function is now exported from
1066 the Python dll again.
1067
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001068- Bug #1191458: tracing over for loops now produces a line event
1069 on each iteration. Fixing this problem required changing the .pyc
1070 magic number. This means that .pyc files generated before 2.5c1
1071 will be regenerated.
1072
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001073- Bug #1333982: string/number constants were inappropriately stored
1074 in the byte code and co_consts even if they were not used, ie
1075 immediately popped off the stack.
1076
Georg Brandle9462c72006-08-04 18:03:37 +00001077- Fixed a reference-counting problem in property().

1080Library
1081-------
1082
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001083- Fix a bug in the ``compiler`` package that caused invalid code to be
1084 generated for generator expressions.
1085
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001086- The distutils version has been changed to 2.5.0. The change to
1087 keep it programmatically in sync with the Python version running
1088 the code (introduced in 2.5b3) has been reverted. It will continue
1089 to be maintained manually as static string literal.
1090
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001091- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001092 and this cannot be converted to the required C type, an exception is
1093 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001094 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001095
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001096- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001097 an exception.
1098
Tim Peterscbdd3502006-09-05 01:47:53 +00001099- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001100 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001101 workarounds for clocks with low resolution, to stop the code yielding
1102 duplicate UUIDs.
1103
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001104- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1105 before raising SystemExit, allowing IDLE to honor quit() and exit().
1106
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001107- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1108
Georg Brandl7a1af772006-08-14 21:55:28 +00001109- Patch #1536071: trace.py should now find the full module name of a
1110 file correctly even on Windows.
1111
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001112- logging's atexit hook now runs even if the rest of the module has
1113 already been cleaned up.
1114
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001115- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001116
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001117- Bug #1531405, format_exception no longer raises an exception if
1118 str(exception) raised an exception.
1119
Neil Schemenauer06ded092006-08-04 16:20:30 +00001120- Fix a bug in the ``compiler`` package that caused invalid code to be
1121 generated for nested functions.

1138 uses the _as_parameter_ attribute when objects are passed to foreign
1139 function calls. The ctypes version number was changed to 1.0.1.
1140
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001141- Bug #1530559, struct.pack raises TypeError where it used to convert.

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001196- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001197 returned a long (see PEP 353).
1198
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001199- Bug #1515471: string.replace() accepts character buffers again.
1200
Neal Norwitz07aadb12006-07-30 06:55:48 +00001201- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1202 This provides the proper warning for struct.pack().
1203 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1204
Neal Norwitz0d62a062006-07-30 06:53:31 +00001205- Patch #1531113: Fix augmented assignment with yield expressions.
1206 Also fix a SystemError when trying to assign to yield expressions.
1207
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001208- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1209 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1210 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1211 excessive filesystem operations during imports.
1212
Tim Petersbc24eee2006-07-27 01:14:53 +00001213- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1214 operations on signed longs that are formally undefined by C.
1215 Unfortunately, at least one compiler now cares about that, so complicated
1216 the code to make that compiler happy again.
1217
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001218- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1219
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001220- Patch #1232023: Stop including current directory in search
1221 path on Windows.
1222
Neal Norwitze1fdb322006-07-21 05:32:28 +00001223- Fix some potential crashes found with failmalloc.
1224
Neal Norwitze7563102006-07-17 01:00:16 +00001225- Fix warnings reported by Klocwork's static analysis tool.
1226
Neal Norwitz84be93b2006-07-16 01:50:38 +00001227- Bug #1512814, Fix incorrect lineno's when code within a function
1228 had more than 255 blank lines.
1229
Georg Brandl9dceedb2006-07-12 15:31:17 +00001230- Patch #1521179: Python now accepts the standard options ``--help`` and
1231 ``--version`` as well as ``/?`` on Windows.
1232
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001233- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001234 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001235 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001236
Tim Peters112aad32006-07-19 00:03:19 +00001237- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001238 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001239 new ``sys._current_frames()`` returns a dictionary with one entry,
1240 mapping the faux "thread id" 0 to the current frame.
1241
Ronald Oussoren3075e162006-07-25 20:28:55 +00001242- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001243
Ronald Oussoren3075e162006-07-25 20:28:55 +00001244

1246-------
1247
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001248- Correction of patch #1455898: In the mbcs decoder, set final=False
1249 for stream decoder, but final=True for the decode function.
1250
Georg Brandl07fec3a2006-08-01 18:49:24 +00001251- os.urandom no longer masks unrelated exceptions like SystemExit or
1252 KeyboardInterrupt.
1253
Tim Peters4643c2f2006-08-10 22:45:34 +00001254- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001255 shutil.copytree on Windows
1256
Georg Brandle34ac7c2006-07-30 11:07:23 +00001257- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1258 refers to file descriptors, not file objects.
1259
Tim Peterscbdd3502006-09-05 01:47:53 +00001260- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001261 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001262 #1513611, and probably others.
1263
Georg Brandledd9b0d2006-07-29 09:33:26 +00001264- Bug #1441397: The compiler module now recognizes module and function
1265 docstrings correctly as it did in Python 2.4.
1266
Tim Peters6f681472006-07-27 23:44:37 +00001267- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1268 lost that tests are sorted by name before being run. This rarely
1269 matters for well-written tests, but can create baffling symptoms if
1270 side effects from one test to the next affect outcomes. ``DocTestFinder``
1271 has been changed to sort the list of tests it returns.
1272
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001273- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001274 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001275
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001276- Bug #978833: Really close underlying socket in _socketobject.close.
1277
Georg Brandldb232dc2006-08-20 13:15:43 +00001278- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1279 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001280
Georg Brandlcf0c1722006-07-26 07:23:32 +00001281- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1282 to recursive calls and call it with the failing package name.
1283
Martin v. Löwis0b483032006-07-25 09:53:12 +00001284- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1285
Georg Brandlc13c34c2006-07-24 14:09:56 +00001286- Patch #1515343: Fix printing of deprecated string exceptions with a
1287 value in the traceback module.
1288
Greg Ward48fae7a2006-07-23 16:05:51 +00001289- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1290
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001291- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1292
Brett Cannoncaebe222006-07-18 04:41:36 +00001293- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1294 argument tuple. For arguments where zero is illegal, the value is forced to
1295 the minimum value that is correct. This is to support an undocumented but
1296 common way people used to fill in inconsequential information in the time
1297 tuple pre-2.4.
1298
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001299- Patch #1220874: Update the binhex module for Mach-O.
1300
Barry Warsawb110bad2006-07-21 14:51:07 +00001301- The email package has improved RFC 2231 support, specifically for
1302 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1303 (name*0=<blah>) parameter continuations. This may change the types of
1304 values returned from email.message.Message.get_param() and friends.
1305 Specifically in some cases where non-encoded continuations were used,
1306 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1307 will just return the string (since non-encoded continuations don't have
1308 charset and language parts).
1309
1310 Also, whereas % values were decoded in all parameter continuations, they are
1311 now only decoded in encoded parameter parts.
1312
Ronald Oussoren3075e162006-07-25 20:28:55 +00001313- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1314
1315- Bug #1517996: IDLE now longer shows the default Tk menu when a
1316 path browser, class browser or debugger is the frontmost window on MacOS X
1317
Barry Warsaw00decd72006-07-27 23:43:15 +00001318- Patch #1520294: Support for getset and member descriptors in types.py,
1319 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1320 of an object against these built-in types and more importantly, for getting
1321 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001324Extension Modules
1325-----------------
1326
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001327- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1328 a socket operation on a socket with a timeout, the exception will be
1329 caught correctly. Previously, the exception was not caught.
1330
Thomas Heller1393d6a2006-07-28 21:43:20 +00001331- Patch #1529514: The _ctypes extension is now compiled on more
1332 openbsd target platforms.
1333
Tim Peters9cab5932006-07-28 00:30:00 +00001334- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1335 a memory leak, affecting pickles and deep copies.
1336
Tim Petersbc24eee2006-07-27 01:14:53 +00001337- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001338 Paul Eggert.
1339
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001340- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1341
Thomas Hellerce049a02006-07-14 17:51:14 +00001342- Patch #1521817: Index range checking on ctypes arrays containing
1343 exactly one element enabled again. This allows iterating over these
1344 arrays, without the need to check the array size before.
1345
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001346- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001347 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001348 /dev/null in certain cases; this is now fixed.
1349
Thomas Heller47d7a062006-07-12 08:43:47 +00001350- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1351 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001352
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001353- Because of a misspelled preprocessor symbol, ctypes was always
1354 compiled without thread support; this is now fixed.
1355
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001356- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1357 methods now allow their database parameter to be None as the
1358 sleepycat API allows.
1359
Matt Flemingec926502006-07-28 11:27:27 +00001360- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1361 bluetooth API compared with Linux and FreeBSD.
1362
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001363Tests
1364-----
1365
1366- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1367 how long the test file should take to play. Now accepts taking 2.93 secs
1368 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1369
Georg Brandl4793aa32006-07-28 18:31:39 +00001370- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1371 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1372 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001379Mac
1380---
1381
1382- PythonLauncher now works correctly when the path to the script contains
1383 characters that are treated specially by the shell (such as quotes).
1384
1385- Bug #1527397: PythonLauncher now launches scripts with the working directory
1386 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001387 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001388 expect.

1397-----------------
1398
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001399- Bug #1441486: The literal representation of -(sys.maxint - 1)
1400 again evaluates to a int object, not a long.
1401
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001402- Bug #1501934: The scope of global variables that are locally assigned
1403 using augmented assignment is now correctly determined.
1404
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001405- Bug #927248: Recursive method-wrapper objects can now safely
1406 be released.
1407
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001408- Bug #1417699: Reject locale-specific decimal point in float()
1409 and atof().
1410
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001411- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1412 omit a default "error" argument for NULL pointer. This allows
1413 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001414
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001415- Bug #1519018: 'as' is now validated properly in import statements.
1416
Neal Norwitz28746ab2006-07-09 22:14:42 +00001417- On 64 bit systems, int literals that use less than 64 bits are
1418 now ints rather than longs.
1419
Neal Norwitzed657552006-07-10 00:04:44 +00001420- Bug #1512814, Fix incorrect lineno's when code at module scope
1421 started after line 256.
1422
Tim Peters32a83612006-07-10 21:08:24 +00001423- New function ``sys._current_frames()`` returns a dict mapping thread
1424 id to topmost thread stack frame. This is for expert use, and is
1425 especially useful for debugging application deadlocks. The functionality
1426 was previously available in Fazal Majid's ``threadframe`` extension
1427 module, but it wasn't possible to do this in a wholly threadsafe way from
1428 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001433- Bug #1257728: Mention Cygwin in distutils error message about a missing
1434 VS 2003.
1435
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001436- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1437
Tim Peters32a83612006-07-10 21:08:24 +00001438- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001439 environment variable to be set in order to the SDK environment
1440 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +00001444- warnings.py now ignores ImportWarning by default
1445
Thomas Woutersadd19112006-07-05 11:03:49 +00001446- string.Template() now correctly handles tuple-values. Previously,
1447 multi-value tuples would raise an exception and single-value tuples would
1448 be treated as the value they contain, instead.
1449
Martin v. Löwisede77f52006-07-03 13:01:35 +00001450- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1451 even if some data are received.
1452
Martin v. Löwis45482392006-07-03 12:28:58 +00001453- Bug #1267547: Put proper recursive setup.py call into the
1454 spec file generated by bdist_rpm.
1455
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001456- Bug #1514693: Update turtle's heading when switching between
1457 degrees and radians.
1458
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001459- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001460 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001461
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001462- Bug #1514703: Only setup canvas window in turtle when the canvas
1463 is created.
1464
Martin v. Löwis7596e832006-07-01 15:33:37 +00001465- Bug #1513223: .close() of a _socketobj now releases the underlying
1466 socket again, which then gets closed as it becomes unreferenced.
1467
Fred Drake10497c82006-06-29 02:57:48 +00001468- Bug #1504333: Make sgmllib support angle brackets in quoted
1469 attribute values.
1470
1471- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1472 sgmllib ('[' and ']' were not accepted).
1473
Georg Brandl1be63af2006-06-28 20:23:25 +00001474- Fix a bug in the turtle module's end_fill function.

Brett Cannon53ab5b72006-06-22 16:49:14 +00001476- Bug #1510580: The 'warnings' module improperly required that a Warning
1477 category be either a types.ClassType and a subclass of Warning. The proper
1478 check is just that it is a subclass with Warning as the documentation states.
1479
Georg Brandlad29e632006-06-21 17:45:17 +00001480- The compiler module now correctly compiles the new try-except-finally
1481 statement (bug #1509132).
1482
Neal Norwitz60373cd2006-06-22 06:30:50 +00001483- The wsgiref package is now installed properly on Unix.
1484
Vinay Sajip28e57612006-07-01 10:45:20 +00001485- A bug was fixed in logging.config.fileConfig() which caused a crash on
1486 shutdown when fileConfig() was called multiple times.
1487
Gerhard Häring762fbd32006-07-02 17:48:30 +00001488- The sqlite3 module did cut off data from the SQLite database at the first
1489 null character before sending it to a custom converter. This has been fixed
1490 now.
1491
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001492Extension Modules
1493-----------------
1494
Tim Peters112aad32006-07-19 00:03:19 +00001495- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1496 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1497 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001498
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001499- Assigning None to pointer type fields in ctypes structures possible
1500 overwrote the wrong fields, this is fixed now.
1501
1502- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1503 on non-Windows platforms.
1504
1505- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1506 integer or long, without range checking.
1507
1508- Patch #1517790: It is now possible to use custom objects in the ctypes
1509 foreign function argtypes sequence as long as they provide a from_param
1510 method, no longer is it required that the object is a ctypes type.
1511
1512- The '_ctypes' extension module now works when Python is configured
1513 with the --without-threads option.
1514
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001515- Bug #1513646: os.access on Windows now correctly determines write
1516 access, again.
1517
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001518- Bug #1512695: cPickle.loads could crash if it was interrupted with
1519 a KeyboardInterrupt.
1520
Neal Norwitza12aa882006-07-06 06:45:08 +00001521- Bug #1296433: parsing XML with a non-default encoding and
1522 a CharacterDataHandler could crash the interpreter in pyexpat.
1523
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001524- Patch #1516912: improve Modules support for OpenVMS.

1530
Tim Peters32a83612006-07-10 21:08:24 +00001531- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001532 Previously, the slight difference could cause compilation errors of the
1533 'zlib' module on systems with more than one version of zlib.
1534
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001535- The MSI compileall step was fixed to also support a TARGETDIR
1536 with spaces in it.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001565
1566Core and builtins
1567-----------------
1568
Georg Brandla56b9152006-06-19 06:35:54 +00001569- Patch #1507676: Error messages returned by invalid abstract object operations
1570 (such as iterating over an integer) have been improved and now include the
1571 type of the offending object to help with debugging.
1572
Brett Cannonea3912b2006-06-13 21:46:41 +00001573- Bug #992017: A classic class that defined a __coerce__() method that returned
1574 its arguments swapped would infinitely recurse and segfault the interpreter.
1575
Neal Norwitz909eb122006-06-12 02:13:21 +00001576- Fix the socket tests so they can be run concurrently.
1577
Neal Norwitzb9845e72006-06-12 02:11:18 +00001578- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001579 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001580
Brett Cannon22565aa2006-06-09 22:31:23 +00001581- Bug #532646: object.__call__() will continue looking for the __call__
1582 attribute on objects until one without one is found. This leads to recursion
1583 when you take a class and set its __call__ attribute to an instance of the
1584 class. Originally fixed for classic classes, but this fix is for new-style.
1585 Removes the infinite_rec_3 crasher.
1586
Georg Brandl24250812006-06-09 18:45:48 +00001587- The string and unicode methods startswith() and endswith() now accept
1588 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1589
Brett Cannonde3b0522006-06-08 17:00:45 +00001590- Buffer objects, at the C level, never used the char buffer
1591 implementation even when the char buffer for the wrapped object was
1592 explicitly requested (originally returned the read or write buffer).
1593 Now a TypeError is raised if the char buffer is not present but is
1594 requested.
1595
Georg Brandlddbaa662006-06-04 21:56:52 +00001596- Patch #1346214: Statements like "if 0: suite" are now again optimized
1597 away like they were in Python 2.4.
1598
Georg Brandlb7c8f542006-05-27 12:30:25 +00001599- Builtin exceptions are now full-blown new-style classes instead of
1600 instances pretending to be classes, which speeds up exception handling
1601 by about 80% in comparison to 2.5a2.
1602
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001603- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1604 Unicode 4.1.
1605
Georg Brandlf4ef1162006-05-26 18:03:31 +00001606- Patch #921466: sys.path_importer_cache is now used to cache valid and
1607 invalid file paths for the built-in import machinery which leads to
1608 fewer open calls on startup.
1609
Tim Peters696cf432006-05-24 21:10:40 +00001610- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1611 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1612 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1613 the number of input digits (it was and remains linear-time for bases
1614 2, 4, 8, 16 and 32).
1615
Tim Petersb713ec22006-05-23 18:45:30 +00001616- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1617 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1618 an integer close to ``sys.maxint``. This was repaired by patch
1619 #1335972, which also gives a nice speedup.
1620
Richard Jonescebbefc2006-05-23 18:28:17 +00001621- Patch #1337051: reduced size of frame objects.
1622
1623- PyErr_NewException now accepts a tuple of base classes as its
1624 "base" parameter.
1625
Richard Jones7c88dcc2006-05-23 10:37:38 +00001626- Patch #876206: function call speedup by retaining allocated frame
1627 objects.
1628
Georg Brandl7b90e162006-05-18 07:01:27 +00001629- Bug #1462152: file() now checks more thoroughly for invalid mode
1630 strings and removes a possible "U" before passing the mode to the
1631 C library function.
1632
Neal Norwitz1004a532006-05-15 07:17:23 +00001633- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1634
Neal Norwitz373f0a72006-05-15 07:04:36 +00001635- Bug #1487966: Fix SystemError with conditional expression in assignment
1636
Martin v. Löwis879768d2006-05-11 13:28:43 +00001637- WindowsError now has two error code attributes: errno, which carries
1638 the error values from errno.h, and winerror, which carries the error
1639 values from winerror.h. Previous versions put the winerror.h values
1640 (from GetLastError()) into the errno attribute.
1641
Martin v. Löwis77736712006-05-04 05:51:03 +00001642- Patch #1475845: Raise IndentationError for unexpected indent.
1643
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001644- Patch #1479181: split open() and file() from being aliases for each other.
1645
Tim Peters44bd9862006-06-01 13:49:23 +00001646- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1647 methods were always silently ignored by dictionaries when comparing keys.
1648 They are now passed through (except when using the C API function
1649 ``PyDict_GetItem()``, whose semantics did not change).
1650
1651- Bug #1456209: In some obscure cases it was possible for a class with a
1652 custom ``__eq__()`` method to confuse dict internals when class instances
1653 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1654 No, you don't have any code that did this ;-)

1662
Brett Cannon6ee7d012006-06-08 16:23:04 +00001663- Change binascii.hexlify to accept a read-only buffer instead of only a char
1664 buffer and actually follow its documentation.
1665
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001666- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1667
Nick Coghlanc649ec52006-05-29 12:43:05 +00001668- Patch #1478788 (modified version): The functional extension module has
1669 been renamed to _functools and a functools Python wrapper module added.
1670 This provides a home for additional function related utilities that are
1671 not specifically about functional programming. See PEP 309.
1672
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001673- Patch #1493701: performance enhancements for struct module.

1678 copy() method.
1679
Andrew MacIntyre92913322006-06-13 15:04:24 +00001680- Patch #1454481: thread stack size is now tunable at runtime for thread
1681 enabled builds on Windows and systems with Posix threads support.
1682
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001683- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1684 (up to the system limit of 32K characters).
1685
1686- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1687 As a result, these functions now raise WindowsError instead of OSError.
1688
Tim Peters7a822da2006-05-25 21:50:17 +00001689- ``time.clock()`` on Win64 should use the high-performance Windows
1690 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1691 Windows platforms).
1692
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001693- Calling Tk_Init twice is refused if the first call failed as that
1694 may deadlock.
1695
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001696- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1697 accept it without potentially using an uninitialized pointer.
1698
1699- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1700 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1701 patch numbers 1494885 and 1494902]

1707 parameter is supplied. [SF pybsddb bug #1477863]
1708
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001709- bsddb: the __len__ method of a DB object has been fixed to return correct
1710 results. It could previously incorrectly return 0 in some cases.
1711 Fixes SF bug 1493322 (pybsddb bug 1184012).
1712
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001713- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1714 aborts the db transaction safely when a modifier callback fails.
1715 Fixes SF python patch/bug #1408584.
1716
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001717- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001718 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001719 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1720 database calls that would previously deadlock. [SF python bug #775414]
1721

1750 double-byte encodings.
1751
Tim Peters43898b42006-06-14 04:09:25 +00001752- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1753 guarantee that adjacent triples in the return list always describe
1754 non-adjacent blocks. Previously, a pair of matching blocks could end
1755 up being described by multiple adjacent triples that formed a partition
1756 of the matching pair.
1757
Greg Ward0e0c9f42006-06-11 16:24:11 +00001758- Bug #1498146: fix optparse to handle Unicode strings in option help,

Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001766- The wsgiref package has been added to the standard library.
1767
Nick Coghlan676725d2006-06-08 13:54:49 +00001768- The functions update_wrapper() and wraps() have been added to the functools
1769 module. These make it easier to copy relevant metadata from the original
1770 function when writing wrapper functions.
1771
Tim Petersd6a9eef2006-06-05 01:48:21 +00001772- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1773 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001774
Martin v. Löwis3f767792006-06-04 19:36:28 +00001775- Patch #1359618: Speed up charmap encoder by using a trie structure
1776 for lookup.
1777
Tim Petersd609b1a2006-06-02 23:22:51 +00001778- The functions in the ``pprint`` module now sort dictionaries by key
1779 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1780 if and only if its display required more than one line, although that
1781 wasn't documented. The new behavior increases predictability; e.g.,
1782 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1783
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001784- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1785 (thanks for J. J. Lee).
1786
Georg Brandl2b330372006-05-28 20:23:12 +00001787- Patch #1496206: improve urllib2 handling of passwords with respect to
1788 default HTTP and HTTPS ports.
1789
George Yoshidaf3c65de2006-05-28 16:39:09 +00001790- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1791
Bob Ippolito7298f272006-05-23 18:43:47 +00001792- Patch #1281707: speed up gzip.readline.
1793
Georg Brandlb89316f2006-05-17 15:51:16 +00001794- Patch #1180296: Two new functions were added to the locale module:
1795 format_string() to get the effect of "format % items" but locale-aware,
1796 and currency() to format a monetary number with currency sign.
1797
Georg Brandle3a25832006-05-17 14:56:04 +00001798- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1799 and several features added, such as speed and geometry control.
1800
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001801- Patch #1488881: add support for external file objects in bz2 compressed
1802 tarfiles.
1803
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001804- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1805 stdout arguments, making it possible to redirect input and output
1806 for remote debugging.
1807
1808- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1809 a couple of issues, notably handling of long file names using the
1810 GNU LONGNAME extension.
1811
1812- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1813 new flag when ``name`` is already the name of an option flag.
1814
1815- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1816 package.
1817
1818- Patch #1472854: make the rlcompleter.Completer class usable on non-
1819 UNIX platforms.
1820
1821- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1822
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001823- Bug #1472827: correctly escape newlines and tabs in attribute values in
1824 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001854What's New in Python 2.5 alpha 2?
1855=================================
1856
1857*Release date: 27-APR-2006*
1858
1859Core and builtins
1860-----------------
1861
Thomas Heller1b046642006-04-18 18:51:06 +00001862- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1863 by converting these apis from macros into exported functions again:
1864
1865 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1866 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1867 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1868 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1869 PyRun_String Py_CompileString
1870
Martin v. Löwis45294a92006-04-18 06:24:08 +00001871- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1872
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001873- All uses of PyStructSequence_InitType have been changed to initialize
1874 the type objects only once, even if the interpreter is initialized
1875 multiple times.
1876
Neal Norwitz61546162006-04-14 05:20:28 +00001877- Bug #1454485, array.array('u') could crash the interpreter. This was
1878 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1879 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1880
1881- Py_UNICODE is unsigned. It was always documented as unsigned, but
1882 due to a bug had a signed value in previous versions.
1883
Tim Peters3a5e8b12006-04-11 01:44:07 +00001884- Patch #837242: ``id()`` of any Python object always gives a positive
1885 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1886 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001887 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001888 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001889
Tim Peters3a5e8b12006-04-11 01:44:07 +00001890 def __hash__(self):
1891 return id(self) # WRONG
1892
1893 because a hash result must be a (short) Python int but it was always
1894 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001895 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001896 was always usable as a hash value before this patch. That's no longer
1897 necessarily so.
1898
1899- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001900 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001901 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001902 #1454844)
1903
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001904- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1905 involving generators that have paused outside of any ``try`` or ``with``
1906 blocks. (In 2.5a1, a paused generator that was part of a reference
1907 cycle could not be garbage collected, regardless of whether it was
1908 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001909

1915
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001916- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1917 fails with an error condition.
1918
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001919- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1920
1921- Bug #1117761: bsddb.*open() no longer raises an exception when using
1922 the cachesize parameter.
1923
1924- Bug #1149413: bsddb.*open() no longer raises an exception when using
1925 a temporary db (file=None) with the 'n' flag to truncate on open.
1926
1927- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1928 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001929
Armin Rigoa9017c32006-04-19 11:50:27 +00001930- Patch #1062014: AF_UNIX sockets under Linux have a special
1931 abstract namespace that is now fully supported.

1937 of the process using the returncode attribute, instead of
1938 abusing errno.
1939
Tim Peters711bf302006-04-25 03:31:36 +00001940- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1941 a doctest to be skipped (the code is not run, and the expected output
1942 or exception is ignored).
1943
Nick Coghlanda2268f2006-04-24 04:37:15 +00001944- Fixed contextlib.nested to cope with exceptions being raised and
1945 caught inside exit handlers.
1946
Greg Wardab05edc2006-04-23 03:47:58 +00001947- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1948 hex, octal, or binary; add ``append_const`` action; keep going if
1949 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1950 added ``epilog`` for better help generation).
1951
Tim Peters21fbd572006-04-21 21:18:10 +00001952- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1953 called from a thread spawned as a side effect of importing a module.
1954
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001955- The pydoc module now supports documenting packages contained in
1956 .zip or .egg files.
1957
1958- The pkgutil module now has several new utility functions, such
1959 as ``walk_packages()`` to support working with packages that are either
1960 in the filesystem or zip files.
1961
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001962- The mailbox module can now modify and delete messages from
1963 mailboxes, in addition to simply reading them. Thanks to Gregory
1964 K. Johnson for writing the code, and to the 2005 Google Summer of
1965 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001966
Tim Petersc7605f22006-04-17 21:12:33 +00001967- The ``__del__`` method of class ``local`` in module ``_threading_local``
1968 returned before accomplishing any of its intended cleanup.
1969
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001970- Patch #790710: Add breakpoint command lists in pdb.

1975
Anthony Baxtere29002c2006-04-12 12:07:31 +00001976- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1977 Windows. Bug #1469163.
1978
Phillip J. Eby47032112006-04-11 01:07:43 +00001979- The warnings, linecache, inspect, traceback, site, and doctest modules
1980 were updated to work correctly with modules imported from zipfiles or
1981 via other PEP 302 __loader__ objects.
1982
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001983- Patch #1467770: Reduce usage of subprocess._active to processes which

1995
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001996- The Makefile now has a reindent target, which runs reindent.py on
1997 the library.
1998
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001999- Patch #1470875: Building Python with MS Free Compiler

Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002005 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002006 CXX from --with-cxx-main, see description in README.
2007

2015
Anthony Baxter51bcb682006-04-05 14:51:42 +00002016Tests

2023
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002024- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2025 it separately and by hand. It also wasn't cleaning up its changes to
2026 the current Decimal context.
2027
Thomas Woutersabd08882006-04-26 15:53:30 +00002028- regrtest.py now has a -M option to run tests that test the new limits of
2029 containers, on 64-bit architectures. Running these tests is only sensible
2030 on 64-bit machines with more than two gigabytes of memory. The argument
2031 passed is the maximum amount of memory for the tests to use.

2045 and attempted to bring other PEP 343 related documentation into
2046 line with the implementation and/or python-dev discussions.
2047
Tim Peters8dc73d22006-04-24 02:03:16 +00002048- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002052What's New in Python 2.5 alpha 1?
2053=================================
2054
Anthony Baxterebed3f62006-04-03 15:03:44 +00002055*Release date: 05-APR-2006*

2062
Martin v. Löwisc661b882006-04-20 04:54:23 +00002063- On Windows, .DLL is not an accepted file name extension for
2064 extension modules anymore; extensions are only found if they
2065 end in .PYD.
2066
Martin v. Löwisea62d252006-04-03 10:56:49 +00002067- Bug #1421664: sys.stderr.encoding is now set to the same value as

2075
Hye-Shik Changd478f342006-03-23 12:32:36 +00002076- Patch #1396919: The system scope threads are reenabled on FreeBSD
2077 5.4 and later versions.
2078
Neal Norwitze98ccf62006-03-23 05:39:47 +00002079- Bug #1115379: Compiling a Unicode string with an encoding declaration
2080 now gives a SyntaxError.
2081
Georg Brandlabd1ff82006-03-18 07:59:59 +00002082- Previously, Python code had no easy way to access the contents of a
2083 cell object. Now, a ``cell_contents`` attribute has been added
2084 (closes patch #1170323).
2085
Tim Peterscf79aac2006-03-16 01:14:46 +00002086- Patch #1123430: Python's small-object allocator now returns an arena to
2087 the system ``free()`` when all memory within an arena becomes unused
2088 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2089 freed. Some applications will see a drop in virtual memory size now,
2090 especially long-running applications that, from time to time, temporarily
2091 use a large number of small objects. Note that when Python returns an
2092 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002093 platform C library will in turn return that memory to the operating system.
2094 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002095 appears to be effective at least on Microsoft C and gcc-based systems.
2096 Thanks to Evan Jones for hard work and patience.
2097
Georg Brandl533ff6f2006-03-08 18:09:27 +00002098- Patch #1434038: property() now uses the getter's docstring if there is
2099 no "doc" argument given. This makes it possible to legitimately use
2100 property() as a decorator to produce a read-only property.
2101
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002102- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2103 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2104 of requiring an int or long in slicing and a few other contexts, enabling
2105 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2106
Neal Norwitz995acdf2006-03-07 05:01:00 +00002107- Fixed various bugs reported by Coverity's Prevent tool.
2108
Brett Cannonbf364092006-03-01 04:25:17 +00002109- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2110 new exception base class, BaseException, which has a new message attribute.
2111 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2112 Raising a string exception now raises a DeprecationWarning.
2113
Thomas Woutersfb609f42006-02-28 16:37:25 +00002114- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2115 explicitly relative, using 'from .module import name' to mean 'from the same
2116 package as this module is in. Imports without dots still default to the
2117 old relative-then-absolute, unless 'from __future__ import
2118 absolute_import' is used.
2119
Brett Cannona7446e32006-02-27 23:39:10 +00002120- Properly check if 'warnings' raises an exception (usually when a filter set
2121 to "error" is triggered) when raising a warning for raising string
2122 exceptions.
2123
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002124- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002125 The name was removed from Include/code.h.
2126
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002127- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002128
Guido van Rossum1968ad32006-02-25 22:38:04 +00002129- Patch 1433928:
2130 - The copy module now "copies" function objects (as atomic objects).
2131 - dict.__getitem__ now looks for a __missing__ hook before raising
2132 KeyError.
2133
Tim Peters84ef21c2006-02-28 20:39:06 +00002134- PEP 343: with statement implemented. Needs ``from __future__ import
2135 with_statement``. Use of 'with' as a variable will generate a warning.
2136 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002137 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002138 The following objects have __context__ methods:
2139 - The built-in file type.
2140 - The thread.LockType type.
2141 - The following types defined by the threading module:
2142 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2143 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002144
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002145- Fix the encodings package codec search function to only search
2146 inside its own package. Fixes problem reported in patch #1433198.
2147
2148 Note: Codec packages should implement and register their own
2149 codec search function. PEP 100 has the details.
2150
Tim Peters9ea89d22006-06-04 03:26:02 +00002151- PEP 353: Using ``Py_ssize_t`` as the index type.
2152
2153- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2154 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2155 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2156 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2157 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002158
Neal Norwitzfc76d632006-01-10 06:03:13 +00002159- Patch #1400181, fix unicode string formatting to not use the locale.
2160 This is how string objects work. u'%f' could use , instead of .
2161 for the decimal point. Now both strings and unicode always use periods.
2162
Neal Norwitz671b9e32006-01-09 07:07:12 +00002163- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2164 configure would break checking curses.h.
2165
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002166- Bug #959576: The pwd module is now builtin. This allows Python to be
2167 built on UNIX platforms without $HOME set.
2168
Neal Norwitzc10978f2005-12-19 06:07:16 +00002169- Bug #1072182, fix some potential problems if characters are signed.
2170
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002171- Bug #889500, fix line number on SyntaxWarning for global declarations.
2172
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002173- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2174
Neal Norwitze7214a12005-12-18 05:03:17 +00002175- Support for converting hex strings to floats no longer works.
2176 This was not portable. float('0x3') now raises a ValueError.
2177
Barry Warsaw2a38a862005-12-18 01:27:35 +00002178- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002179 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002180 is now displayed in interactive prompt banner.
2181
Georg Brandlfa166682005-12-17 21:45:17 +00002182- Implementation of PEP 341 - Unification of try/except and try/finally.
2183 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002184 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002185
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002186- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2187 now encodes backslash correctly.
2188
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002189- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2190
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002191- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002192 and long longs.
2193
Neal Norwitz67715f02005-11-09 06:59:35 +00002194- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002195 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002196 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002197
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002198- Replaced most Unicode charmap codecs with new ones using the
2199 new Unicode translate string feature in the builtin charmap
2200 codec; the codecs were created from the mapping tables available
2201 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2202 encodings now include a mapping for the Apple logo)
2203
Tim Peterse3547fd2005-12-16 23:13:57 +00002204- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002205
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002206- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002207
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002208- A new AST parser implementation was completed. The abstract
2209 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002210 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002211
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002212- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002213 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2214
Neal Norwitz708e51a2005-10-03 04:48:15 +00002215- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2216
Neal Norwitz11bd1192005-10-03 00:54:56 +00002217- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2218 Provide a warning when a directory is passed on the command line.
2219
Neal Norwitz40d37812005-10-02 01:48:49 +00002220- Fix segfault with invalid coding.
2221
2222- SF bug #772896: unknown encoding results in MemoryError.
2223
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002224- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002225 supported a __len__() method which evaluated to False when the iterator
2226 was empty.
2227
Guido van Rossum630db602005-09-20 18:49:54 +00002228- On 64-bit platforms, when __len__() returns a value that cannot be
2229 represented as a C int, raise OverflowError.
2230
Skip Montanarof8948ca2005-09-19 03:54:46 +00002231- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002232 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002233
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002234- SF bug #893549: parsing keyword arguments was broken with a few format
2235 codes.
2236
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002237- Changes donated by Elemental Security to make it work on AIX 5.3
2238 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2239 bug #105470: test_pwd fails on 64bit system (Opteron).
2240
Guido van Rossum539c6622005-09-14 17:49:54 +00002241- Changes donated by Elemental Security to make it work on HP-UX 11 on
2242 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2243
Georg Brandl4550b8d2005-08-26 06:43:52 +00002244- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002245 (fixes bug #1119418).
2246
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002247- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2248
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002249- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2250 exceptions that cause a function to exit.
2251
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002252- The implementation of set() and frozenset() was revised to use its
2253 own internal data structure. Memory consumption is reduced by 1/3
2254 and there are modest speed-ups as well. The API is unchanged.
2255
Tim Petersde7990b2005-07-17 23:45:23 +00002256- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2257
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002258- SF bug #1229429: PyObject_CallMethod failed to decrement some
2259 reference counts in some error exit cases.
2260
Tim Petersecc6e6a2005-07-10 22:30:55 +00002261- SF bug #1185883: Python's small-object memory allocator took over
2262 a block managed by the platform C library whenever a realloc specified
2263 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002264 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002265 portable way to copy data from the C-managed block into Python's
2266 small-object space without risking a memory fault. Python's small-object
2267 realloc now leaves such blocks under the control of the platform C
2268 realloc.
2269
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002270- SF bug #1232517: An overflow error was not detected properly when
2271 attempting to convert a large float to an int in os.utime().
2272
Raymond Hettinger3296e692005-06-29 23:29:56 +00002273- SF bug #1224347: hex longs now print with lowercase letters just
2274 like their int counterparts.
2275
Michael W. Hudson188d4362005-06-20 16:52:57 +00002276- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2277 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2278 interpreter states; back out that fix and do a better job (see
2279 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2280 for a longer write-up of the problem).
2281
Michael W. Hudsondf888462005-06-03 14:41:55 +00002282- SF patch #1180995: marshal now uses a binary format by default when
2283 serializing floats.
2284
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002285- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2286 the routines that promise to produce IEEE 754 binary representations
2287 of floats now simply copy bytes around.
2288
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002289- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2290 278.
2291
Brett Cannonc3647ac2005-04-26 03:45:26 +00002292- patch #1109424: int, long, float, complex, and unicode now check for the
2293 proper magic slot for type conversions when subclassed. Previously the
2294 magic slot was ignored during conversion. Semantics now match the way
2295 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002296 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002297 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002298 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002299
Barry Warsawc8d907c2005-04-19 23:43:40 +00002300- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2301 NULL, now raise an AttributeError when attempting to set or delete the
2302 attribute. Previously a TypeError was raised, but this was inconsistent
2303 with the equivalent pure-Python implementation.
2304
Michael W. Hudson774479c2005-04-18 08:46:17 +00002305- It is now safe to call PyGILState_Release() before
2306 PyEval_InitThreads() (note that if there is reason to believe there
2307 are multiple threads around you still must call PyEval_InitThreads()
2308 before using the Python API; this fix is for extension modules that
2309 have no way of knowing if Python is multi-threaded yet).
2310
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002311- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2312 disabled caused a crash.
2313
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002314- Bug #1165306: instancemethod_new allowed the creation of a method
2315 with im_class == im_self == NULL, which caused a crash when called.
2316
Tim Petersecc6e6a2005-07-10 22:30:55 +00002317- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002318 fixes the crash seen in bug #1165761
2319
Raymond Hettinger96229b12005-03-11 06:49:40 +00002320- Added two new builtins, any() and all().
2321
Brett Cannon409d8f22005-03-05 06:47:57 +00002322- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002323 (e.g., ``class C(): pass`` is no longer a syntax error).
2324 Patch #1176012 added support to the 'parser' module and 'compiler' package
2325 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002326
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002327- Patch #1115086: Support PY_LONGLONG in structmember.
2328
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002329- Bug #1155938: new style classes did not check that __init__() was
2330 returning None.
2331
Tim Petersecc6e6a2005-07-10 22:30:55 +00002332- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002333 ('\') with a specific error message.
2334
Martin v. Löwisff232d72005-03-03 09:24:38 +00002335- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2336
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002337- Bug #1124295: the __name__ attribute of file objects was

2359 unicode instance if the argument is not an instance of basestring and
2360 calling __str__ on the argument returns a unicode instance.
2361
Tim Petersf4e69282006-02-27 17:15:31 +00002362- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2363 current thread state when the auto-GIL-state machinery knows about
2364 it (since the thread state is being deleted, continuing to remember it
2365 can't help, but can hurt if another thread happens to get created with
2366 the same thread id).

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002561
Nick Coghlan43832302006-04-23 17:04:07 +00002562- PEP 338: new module runpy defines a run_module function to support
2563 executing modules which provide access to source code or a code object
2564 via the PEP 302 import mechanisms.
2565

2574 in attribute values.
2575
Anthony Baxterc51ee692006-04-01 00:57:31 +00002576- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002577 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002578 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002579 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002581- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2582 aren't officially supported here, and trying to use them will probably

Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002605- email 4.0 package now integrated. This is largely the same as the email 3.0
2606 package that was included in Python 2.3, except that PEP 8 module names are
2607 now used (e.g. mail.message instead of email.Message). The MIME classes
2608 have been moved to a subpackage (e.g. email.mime.text instead of
2609 email.MIMEText). The old names are still supported for now. Several
2610 deprecated Message methods have been removed and lots of bugs have been
2611 fixed. More details can be found in the email package documentation.
2612
Walter Dörwald40108c92006-03-27 08:15:44 +00002613- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2614 (a subclass of tuple) that provides incremental decoders and encoders
2615 (a way to use stateful codecs without the stream API). Python functions
2616 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2617 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2618 have been added.

2621 a ValueError instead of a StopIteration now (like file and cString.String do).
2622 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2623 called before (like file and StringIO.StringIO do).

2699 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2700 Ronald L. Rivest offered this advice for Python:
2701
2702 "The consensus of researchers in this area (at least as
2703 expressed at the NIST Hash Function Workshop 10/31/05),
2704 is that SHA-256 is a good choice for the time being, but
2705 that research should continue, and other alternatives may
2706 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002707

Guido van Rossumd0641422005-02-03 15:01:24 +00002867- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2868 disables recursive traversal through instance attributes, which can
2869 be exploited in various ways.
2870
Tim Peterse3547fd2005-12-16 23:13:57 +00002871- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002872 flags on the HTTP listening socket.
2873
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002874- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2875 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2876
Fred Drakefbdeaad2006-07-29 16:56:15 +00002877- Patches #893642, #1039083: add allow_none, encoding arguments to
2878 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002879
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002880- Bug #1110478: Revert os.environ.update to do putenv again.
2881
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002882- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2883
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002884- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2885
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002886- Enhancements to the csv module:
2887
2888 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002889 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002890 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002891 + Dialect parameter parsing has been re-implemented to improve error
2892 reporting.
2893 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2894 dictates.
2895 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002896 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002897 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002898 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2899 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002900 + reader now allows \r characters to be quoted (previously it only allowed
2901 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002902 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002903 + Dialect classes passed to the module are no longer instantiated by
2904 the module before being parsed (the former validation scheme required
2905 this, but the mechanism was unreliable).
2906 + The dialect registry now contains instances of the internal
2907 C-coded dialect type, rather than references to python objects.
2908 + the internal c-coded dialect type is now immutable.
2909 + register_dialect now accepts the same keyword dialect specifications
2910 as the reader and writer, allowing the user to register dialects
2911 without first creating a dialect class.
2912 + a configurable limit to the size of parsed fields has been added -
2913 previously, an unmatched quote character could result in the entire
2914 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002915 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002916 the parser field size limit (returning the former limit). The initial
2917 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002918 + A line_num attribute has been added to the reader object, which tracks
2919 the number of lines read from the source iterator. This is not
2920 the same as the number of records returned, as records can span
2921 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002922 + reader and writer objects were not being registered with the cyclic-GC.
2923 This has been fixed.
2924
Brett Cannone6539c42005-01-08 02:43:53 +00002925- _DummyThread objects in the threading module now delete self.__block that is
2926 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2927 lock primitives tend to be limited in number and thus should not be wasted on
2928 a _DummyThread object. Fixes bug #1089632.
2929
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002930- The imghdr module now detects Exif files.
2931
Raymond Hettinger6065d322004-12-20 23:51:53 +00002932- StringIO.truncate() now correctly adjusts the size attribute.
2933 (Bug #951915).
2934
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002935- locale.py now uses an updated locale alias table (built using
2936 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2937 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002938 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002939
Raymond Hettinger3557f422004-12-07 12:02:02 +00002940- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2941
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002942- the pickle module no longer accepts the deprecated None option in the
2943 args tuple returned by __reduce__().
2944
Brett Cannon84667c02004-12-07 03:25:18 +00002945- optparse now optionally imports gettext. This allows its use in setup.py.
2946
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002947- the pickle module no longer uses the deprecated bin parameter.
2948
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002949- the shelve module no longer uses the deprecated binary parameter.
2950
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002951- the pstats module no longer uses the deprecated ignore() method.
2952
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002953- the filecmp module no longer uses the deprecated use_statcache argument.
2954
Raymond Hettinger664347b2004-12-04 21:21:53 +00002955- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2956 extended or overridden by subclasses. Formerly, the subclassed method would
2957 be ignored by the rest of the module. (Bug #1078905).
2958
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002959- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002960 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002961
Walter Dörwald36733692004-12-22 12:50:50 +00002962- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2963 once when a size argument is given. This prevents a buffer overflow in the
2964 tokenizer with very long source lines.
2965
Barry Warsaw538561e2006-01-01 21:48:54 +00002966- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2967 immediately after creating the object, without any intervening
2968 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002969
Skip Montanaro05885812005-01-16 20:48:27 +00002970- The reconvert.quote function can now emit triple-quoted strings. The
2971 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002972
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002973- ``UserString.MutableString`` now supports negative indices in
2974 ``__setitem__`` and ``__delitem__``
2975
Greg Ward40407942005-03-05 02:53:17 +00002976- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2977 correctly.
2978
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002979- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2980 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2981 character even if the user has passed a size parameter to get a proper
2982 line ending. Remove the special handling of a "\r\n" that has been split
2983 between two lines.
2984
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002985- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2986 about illegal code points. The codec now supports PEP 293 style error
2987 handlers.
2988
Walter Dörwald78a78b02005-09-01 12:04:29 +00002989- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002990 from the input stream, so that the output is a byte string in the correct
2991 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002992
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002993- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2994 considering it exactly like a '*'.
2995
Walter Dörwald007f8df2005-10-09 19:42:27 +00002996- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2997 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002998
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002999- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3000
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003001- Patch #1413711: Certain patterns of differences were making difflib
3002 touch the recursion limit.
3003
Walter Dörwald58917a62006-03-31 15:26:22 +00003004- Bug #947906: An object oriented interface has been added to the calendar
3005 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003006 called as a script (e.g. via ``python -mcalendar``). Localized month and
3007 weekday names can be ouput (even if an exotic encoding is used) using
3008 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003009

3012
Neal Norwitz602d3392006-03-31 08:21:40 +00003013- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3014 by using -mieee gcc option.
3015

3017
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003018- Build support for Win64-AMD64 was added.
3019
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003020- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3021
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003022- Patch #881820: look for openpty and forkpty also in libbsd.
3023
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003024- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3025 The zlib module is now builtin on Windows.
3026
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003027- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3028
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003029- Bug #1189330: configure did not correctly determine the necessary
3030 value of LINKCC if python was built with GCC 4.0.
3031
Trent Mick8321b422005-07-26 02:29:21 +00003032- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3033 vulnerability in zlib 1.2.1 and 1.2.2.
3034
Brett Cannon08cd5982005-04-24 22:26:38 +00003035- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3036 flags that change binary compatibility. Changes were also made to
3037 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003038 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003039
Bob Ippolitoed233462005-03-29 13:47:59 +00003040- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3041 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3042 no longer exists). This configure patch makes things right.
3043
Martin v. Löwise2713be2005-03-08 15:03:08 +00003044- Bug #1158607: Build with --disable-unicode again.
3045
Brett Cannon46d96232005-02-16 00:07:19 +00003046- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3047 defined. Discovered as a result of not being able to build on OS X.
3048
Brett Cannon516592f2004-12-07 00:42:59 +00003049- setup.py now uses the directories specified in LDFLAGS using the -L option
3050 and in CPPFLAGS using the -I option for adding library and include
3051 directories, respectively, for compiling extension modules against. This has
3052 led to the core being compiled using the values in CPPFLAGS. It also removes
3053 the need for the special-casing of both DarwinPorts and Fink for darwin since
3054 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3055 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3056 Fink, ``-I/opt/local/include`` for DarwinPorts).
3057
Brett Cannon43802422005-02-10 20:48:03 +00003058- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3059 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3060 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3061 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003063C API
3064-----
3065
Tim Petersc9d78aa2006-03-26 23:27:58 +00003066- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3067 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3068 is obtained via the ``PyObject_`` family, it must be released via the
3069 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3070 always been officially true, but when Python's small-object allocator was
3071 introduced, an attempt was made to cater to a few extension modules
3072 discovered at the time that obtained memory via ``PyObject_New`` but
3073 released it via ``PyMem_DEL``. It's years later, and if such code still
3074 exists it will fail now (probably with segfaults, but calling wrong
3075 low-level memory management functions can yield many symptoms).
3076
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003077- Added a C API for set and frozenset objects.
3078
Raymond Hettinger66517482004-12-03 11:45:13 +00003079- Removed PyRange_New().
3080
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003081- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3082 mapping argument now. This string is used as a mapping table. Byte values
3083 greater than the length of the string and 0xFFFE are treated as undefined
3084 mappings.
