903-----------------
904
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000905- Make _PyGILState_NoteThreadState() static, it was not used anywhere
906 outside of pystate.c and should not be necessary.
907
Brett Cannon19d76c52006-09-09 07:18:44 +0000908- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
909 allows calling unicode() on exceptions classes directly to succeed.
910
Georg Brandlecab6232006-09-06 06:47:02 +0000911- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
912 Also make sure that every exception class has __module__ set to
913 'exceptions'.
914
Georg Brandl37a9e572006-09-06 06:09:34 +0000915- Bug #1550983: emit better error messages for erroneous relative

917
Tim Peterscbdd3502006-09-05 01:47:53 +0000918- Overflow checking code in integer division ran afoul of new gcc
919 optimizations. Changed to be more standard-conforming.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000926- The return tuple from str.rpartition(sep) is (tail, sep, head) where
927 head is the original string if sep was not found.
928
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000929- Bug #1520864: unpacking singleton tuples in list comprehensions and
930 generator expressions (x for x, in ... ) works again. Fixing this problem
931 required changing the .pyc magic number. This means that .pyc files
932 generated before 2.5c2 will be regenerated.

Guido van Rossumc69ac252006-08-10 18:09:25 +00001039What's New in Python 2.5 release candidate 1?
1040=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001041
Anthony Baxterb4096662006-08-16 03:42:26 +00001042*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001043
1044Core and builtins
1045-----------------
1046
Neal Norwitz24b6f202006-09-05 04:43:56 +00001047- Fix infinite recursion when subclassing long and overriding __hash__.
1048
1049- Fix concatenation (+=) of long strings.
1050
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001051- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001052 compared equal or unequal to a string and a UnicodeDecodeError
1053 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001054
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001055 Instead, the equal (==) and unequal (!=) comparison operators will
1056 now issue a UnicodeWarning and interpret the two objects as
1057 unequal. The UnicodeWarning can be filtered as desired using
1058 the warning framework, e.g. silenced completely, turned into an
1059 exception, logged, etc.
1060
1061 Note that compare operators other than equal and unequal will still
1062 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001063
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001064- Fix segfault when doing string formatting on subclasses of long.
1065
1066- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1067 with new-style classes.
1068
1069- Fix bug related to __len__ functions returning negative values with
1070 classic classes.
1071
1072- Patch #1538606, Fix __index__() clipping. There were some problems
1073 discovered with the API and how integers that didn't fit into Py_ssize_t
1074 were handled. This patch attempts to provide enough alternatives
1075 to effectively use __index__.
1076
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001077- Bug #1536021: __hash__ may now return long int; the final hash
1078 value is obtained by invoking hash on the long int.
1079
Thomas Hellerab1049c2006-08-08 17:37:00 +00001080- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1081
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001082- Bug #1535165: fixed a segfault in input() and raw_input() when
1083 sys.stdin is closed.
1084
Thomas Heller74d36f02006-08-04 18:17:40 +00001085- On Windows, the PyErr_Warn function is now exported from
1086 the Python dll again.
1087
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001088- Bug #1191458: tracing over for loops now produces a line event
1089 on each iteration. Fixing this problem required changing the .pyc
1090 magic number. This means that .pyc files generated before 2.5c1
1091 will be regenerated.
1092
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001093- Bug #1333982: string/number constants were inappropriately stored
1094 in the byte code and co_consts even if they were not used, ie
1095 immediately popped off the stack.
1096
Georg Brandle9462c72006-08-04 18:03:37 +00001097- Fixed a reference-counting problem in property().
1098

1100Library
1101-------
1102
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001103- Fix a bug in the ``compiler`` package that caused invalid code to be
1104 generated for generator expressions.
1105
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001106- The distutils version has been changed to 2.5.0. The change to
1107 keep it programmatically in sync with the Python version running
1108 the code (introduced in 2.5b3) has been reverted. It will continue
1109 to be maintained manually as static string literal.
1110
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001111- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001112 and this cannot be converted to the required C type, an exception is
1113 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001114 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001115
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001116- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001117 an exception.
1118
Tim Peterscbdd3502006-09-05 01:47:53 +00001119- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001120 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001121 workarounds for clocks with low resolution, to stop the code yielding
1122 duplicate UUIDs.
1123
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001124- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1125 before raising SystemExit, allowing IDLE to honor quit() and exit().
1126
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001127- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1128
Georg Brandl7a1af772006-08-14 21:55:28 +00001129- Patch #1536071: trace.py should now find the full module name of a
1130 file correctly even on Windows.
1131
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001132- logging's atexit hook now runs even if the rest of the module has
1133 already been cleaned up.
1134
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001135- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001136
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001137- Bug #1531405, format_exception no longer raises an exception if
1138 str(exception) raised an exception.
1139
Neil Schemenauer06ded092006-08-04 16:20:30 +00001140- Fix a bug in the ``compiler`` package that caused invalid code to be
1141 generated for nested functions.

Thomas Heller86720042006-08-14 11:17:48 +00001157- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1158 uses the _as_parameter_ attribute when objects are passed to foreign
1159 function calls. The ctypes version number was changed to 1.0.1.
1160
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001161- Bug #1530559, struct.pack raises TypeError where it used to convert.
1162 Passing float arguments to struct.pack when integers are expected
1163 now triggers a DeprecationWarning.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001200- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1201
Tim Peters4643c2f2006-08-10 22:45:34 +00001202- Bug #1069160. Internal correctness changes were made to
1203 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1204 the documentation was changed to state that the return value
1205 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001208What's New in Python 2.5 beta 3?
1209================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001210
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001211*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001212
1213Core and builtins
1214-----------------
1215
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001216- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001217 returned a long (see PEP 353).
1218
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001219- Bug #1515471: string.replace() accepts character buffers again.
1220
Neal Norwitz07aadb12006-07-30 06:55:48 +00001221- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1222 This provides the proper warning for struct.pack().
1223 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1224
Neal Norwitz0d62a062006-07-30 06:53:31 +00001225- Patch #1531113: Fix augmented assignment with yield expressions.
1226 Also fix a SystemError when trying to assign to yield expressions.
1227
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001228- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1229 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1230 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1231 excessive filesystem operations during imports.
1232
Tim Petersbc24eee2006-07-27 01:14:53 +00001233- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1234 operations on signed longs that are formally undefined by C.
1235 Unfortunately, at least one compiler now cares about that, so complicated
1236 the code to make that compiler happy again.
1237
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001238- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1239
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001240- Patch #1232023: Stop including current directory in search
1241 path on Windows.
1242
Neal Norwitze1fdb322006-07-21 05:32:28 +00001243- Fix some potential crashes found with failmalloc.
1244
Neal Norwitze7563102006-07-17 01:00:16 +00001245- Fix warnings reported by Klocwork's static analysis tool.
1246
Neal Norwitz84be93b2006-07-16 01:50:38 +00001247- Bug #1512814, Fix incorrect lineno's when code within a function
1248 had more than 255 blank lines.
1249
Georg Brandl9dceedb2006-07-12 15:31:17 +00001250- Patch #1521179: Python now accepts the standard options ``--help`` and
1251 ``--version`` as well as ``/?`` on Windows.
1252
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001253- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001254 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001255 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001256
Tim Peters112aad32006-07-19 00:03:19 +00001257- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001258 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001259 new ``sys._current_frames()`` returns a dictionary with one entry,
1260 mapping the faux "thread id" 0 to the current frame.
1261
Ronald Oussoren3075e162006-07-25 20:28:55 +00001262- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001263
Ronald Oussoren3075e162006-07-25 20:28:55 +00001264
Neal Norwitza1f10902006-07-12 07:28:29 +00001265Library
1266-------
1267
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001268- Correction of patch #1455898: In the mbcs decoder, set final=False
1269 for stream decoder, but final=True for the decode function.
1270
Georg Brandl07fec3a2006-08-01 18:49:24 +00001271- os.urandom no longer masks unrelated exceptions like SystemExit or
1272 KeyboardInterrupt.
1273
Tim Peters4643c2f2006-08-10 22:45:34 +00001274- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001275 shutil.copytree on Windows
1276
Georg Brandle34ac7c2006-07-30 11:07:23 +00001277- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1278 refers to file descriptors, not file objects.
1279
Tim Peterscbdd3502006-09-05 01:47:53 +00001280- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001281 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001282 #1513611, and probably others.
1283
Georg Brandledd9b0d2006-07-29 09:33:26 +00001284- Bug #1441397: The compiler module now recognizes module and function
1285 docstrings correctly as it did in Python 2.4.
1286
Tim Peters6f681472006-07-27 23:44:37 +00001287- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1288 lost that tests are sorted by name before being run. This rarely
1289 matters for well-written tests, but can create baffling symptoms if
1290 side effects from one test to the next affect outcomes. ``DocTestFinder``
1291 has been changed to sort the list of tests it returns.
1292
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001293- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001294 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001295
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001296- Bug #978833: Really close underlying socket in _socketobject.close.
1297
Georg Brandldb232dc2006-08-20 13:15:43 +00001298- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1299 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001300
Georg Brandlcf0c1722006-07-26 07:23:32 +00001301- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1302 to recursive calls and call it with the failing package name.
1303
Martin v. Löwis0b483032006-07-25 09:53:12 +00001304- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1305
Georg Brandlc13c34c2006-07-24 14:09:56 +00001306- Patch #1515343: Fix printing of deprecated string exceptions with a
1307 value in the traceback module.
1308
Greg Ward48fae7a2006-07-23 16:05:51 +00001309- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1310
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001311- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1312
Brett Cannoncaebe222006-07-18 04:41:36 +00001313- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1314 argument tuple. For arguments where zero is illegal, the value is forced to
1315 the minimum value that is correct. This is to support an undocumented but
1316 common way people used to fill in inconsequential information in the time
1317 tuple pre-2.4.
1318
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001319- Patch #1220874: Update the binhex module for Mach-O.
1320
Barry Warsawb110bad2006-07-21 14:51:07 +00001321- The email package has improved RFC 2231 support, specifically for
1322 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1323 (name*0=<blah>) parameter continuations. This may change the types of
1324 values returned from email.message.Message.get_param() and friends.
1325 Specifically in some cases where non-encoded continuations were used,
1326 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1327 will just return the string (since non-encoded continuations don't have
1328 charset and language parts).
1329
1330 Also, whereas % values were decoded in all parameter continuations, they are
1331 now only decoded in encoded parameter parts.
1332
Ronald Oussoren3075e162006-07-25 20:28:55 +00001333- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1334
1335- Bug #1517996: IDLE now longer shows the default Tk menu when a
1336 path browser, class browser or debugger is the frontmost window on MacOS X
1337
Barry Warsaw00decd72006-07-27 23:43:15 +00001338- Patch #1520294: Support for getset and member descriptors in types.py,
1339 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1340 of an object against these built-in types and more importantly, for getting
1341 their docstrings printed in the interactive interpreter's help() function.
1342
Ronald Oussoren3075e162006-07-25 20:28:55 +00001343
Neal Norwitza1f10902006-07-12 07:28:29 +00001344Extension Modules
1345-----------------
1346
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001347- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1348 a socket operation on a socket with a timeout, the exception will be
1349 caught correctly. Previously, the exception was not caught.
1350
Thomas Heller1393d6a2006-07-28 21:43:20 +00001351- Patch #1529514: The _ctypes extension is now compiled on more
1352 openbsd target platforms.
1353
Tim Peters9cab5932006-07-28 00:30:00 +00001354- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1355 a memory leak, affecting pickles and deep copies.
1356
Tim Petersbc24eee2006-07-27 01:14:53 +00001357- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001358 Paul Eggert.
1359
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001360- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1361
Thomas Hellerce049a02006-07-14 17:51:14 +00001362- Patch #1521817: Index range checking on ctypes arrays containing
1363 exactly one element enabled again. This allows iterating over these
1364 arrays, without the need to check the array size before.
1365
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001366- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001367 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001368 /dev/null in certain cases; this is now fixed.
1369
Thomas Heller47d7a062006-07-12 08:43:47 +00001370- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1371 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001372
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001373- Because of a misspelled preprocessor symbol, ctypes was always
1374 compiled without thread support; this is now fixed.
1375
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001376- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1377 methods now allow their database parameter to be None as the
1378 sleepycat API allows.
1379
Matt Flemingec926502006-07-28 11:27:27 +00001380- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1381 bluetooth API compared with Linux and FreeBSD.
1382
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001383Tests
1384-----
1385
1386- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1387 how long the test file should take to play. Now accepts taking 2.93 secs
1388 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1389
Georg Brandl4793aa32006-07-28 18:31:39 +00001390- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1391 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1392 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001399Mac
1400---
1401
1402- PythonLauncher now works correctly when the path to the script contains
1403 characters that are treated specially by the shell (such as quotes).
1404
1405- Bug #1527397: PythonLauncher now launches scripts with the working directory
1406 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001407 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001408 expect.

1417-----------------
1418
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001419- Bug #1441486: The literal representation of -(sys.maxint - 1)
1420 again evaluates to a int object, not a long.
1421
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001422- Bug #1501934: The scope of global variables that are locally assigned
1423 using augmented assignment is now correctly determined.
1424
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001425- Bug #927248: Recursive method-wrapper objects can now safely
1426 be released.
1427
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001428- Bug #1417699: Reject locale-specific decimal point in float()
1429 and atof().
1430
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001431- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1432 omit a default "error" argument for NULL pointer. This allows
1433 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001434
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001435- Bug #1519018: 'as' is now validated properly in import statements.
1436
Neal Norwitz28746ab2006-07-09 22:14:42 +00001437- On 64 bit systems, int literals that use less than 64 bits are
1438 now ints rather than longs.
1439
Neal Norwitzed657552006-07-10 00:04:44 +00001440- Bug #1512814, Fix incorrect lineno's when code at module scope
1441 started after line 256.
1442
Tim Peters32a83612006-07-10 21:08:24 +00001443- New function ``sys._current_frames()`` returns a dict mapping thread
1444 id to topmost thread stack frame. This is for expert use, and is
1445 especially useful for debugging application deadlocks. The functionality
1446 was previously available in Fazal Majid's ``threadframe`` extension
1447 module, but it wasn't possible to do this in a wholly threadsafe way from
1448 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001453- Bug #1257728: Mention Cygwin in distutils error message about a missing
1454 VS 2003.
1455
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001456- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1457
Tim Peters32a83612006-07-10 21:08:24 +00001458- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001459 environment variable to be set in order to the SDK environment
1460 for finding the compiler, include files, etc.

Martin v. Löwis388a8c22006-07-06 19:28:03 +00001462- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1463
Nick Coghlan2d792252006-07-06 13:47:18 +00001464- warnings.py now ignores ImportWarning by default
1465
Thomas Woutersadd19112006-07-05 11:03:49 +00001466- string.Template() now correctly handles tuple-values. Previously,
1467 multi-value tuples would raise an exception and single-value tuples would
1468 be treated as the value they contain, instead.
1469
Martin v. Löwisede77f52006-07-03 13:01:35 +00001470- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1471 even if some data are received.
1472
Martin v. Löwis45482392006-07-03 12:28:58 +00001473- Bug #1267547: Put proper recursive setup.py call into the
1474 spec file generated by bdist_rpm.

Martin v. Löwis2b88f632006-07-03 10:19:49 +00001480 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001481
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001482- Bug #1514703: Only setup canvas window in turtle when the canvas
1483 is created.
1484
Martin v. Löwis7596e832006-07-01 15:33:37 +00001485- Bug #1513223: .close() of a _socketobj now releases the underlying
1486 socket again, which then gets closed as it becomes unreferenced.
1487
Fred Drake10497c82006-06-29 02:57:48 +00001488- Bug #1504333: Make sgmllib support angle brackets in quoted
1489 attribute values.
1490
1491- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1492 sgmllib ('[' and ']' were not accepted).
1493

1495
Brett Cannon53ab5b72006-06-22 16:49:14 +00001496- Bug #1510580: The 'warnings' module improperly required that a Warning
1497 category be either a types.ClassType and a subclass of Warning. The proper
1498 check is just that it is a subclass with Warning as the documentation states.
1499
Georg Brandlad29e632006-06-21 17:45:17 +00001500- The compiler module now correctly compiles the new try-except-finally
1501 statement (bug #1509132).
1502
Neal Norwitz60373cd2006-06-22 06:30:50 +00001503- The wsgiref package is now installed properly on Unix.
1504

1506 shutdown when fileConfig() was called multiple times.
1507
Gerhard Häring762fbd32006-07-02 17:48:30 +00001508- The sqlite3 module did cut off data from the SQLite database at the first
1509 null character before sending it to a custom converter. This has been fixed
1510 now.
1511
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001512Extension Modules
1513-----------------
1514
Tim Peters112aad32006-07-19 00:03:19 +00001515- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1516 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1517 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001518
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001519- Assigning None to pointer type fields in ctypes structures possible
1520 overwrote the wrong fields, this is fixed now.
1521
1522- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1523 on non-Windows platforms.
1524
1525- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1526 integer or long, without range checking.
1527
1528- Patch #1517790: It is now possible to use custom objects in the ctypes
1529 foreign function argtypes sequence as long as they provide a from_param
1530 method, no longer is it required that the object is a ctypes type.
1531
1532- The '_ctypes' extension module now works when Python is configured
1533 with the --without-threads option.
1534
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001535- Bug #1513646: os.access on Windows now correctly determines write
1536 access, again.
1537
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001538- Bug #1512695: cPickle.loads could crash if it was interrupted with

1550
Tim Peters32a83612006-07-10 21:08:24 +00001551- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001552 Previously, the slight difference could cause compilation errors of the
1553 'zlib' module on systems with more than one version of zlib.
1554
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001555- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001585
1586Core and builtins
1587-----------------
1588
Georg Brandla56b9152006-06-19 06:35:54 +00001589- Patch #1507676: Error messages returned by invalid abstract object operations
1590 (such as iterating over an integer) have been improved and now include the
1591 type of the offending object to help with debugging.
1592
Brett Cannonea3912b2006-06-13 21:46:41 +00001593- Bug #992017: A classic class that defined a __coerce__() method that returned
1594 its arguments swapped would infinitely recurse and segfault the interpreter.
1595
Neal Norwitz909eb122006-06-12 02:13:21 +00001596- Fix the socket tests so they can be run concurrently.
1597
Neal Norwitzb9845e72006-06-12 02:11:18 +00001598- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001599 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001600
Brett Cannon22565aa2006-06-09 22:31:23 +00001601- Bug #532646: object.__call__() will continue looking for the __call__
1602 attribute on objects until one without one is found. This leads to recursion
1603 when you take a class and set its __call__ attribute to an instance of the
1604 class. Originally fixed for classic classes, but this fix is for new-style.
1605 Removes the infinite_rec_3 crasher.
1606
Georg Brandl24250812006-06-09 18:45:48 +00001607- The string and unicode methods startswith() and endswith() now accept
1608 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1609
Brett Cannonde3b0522006-06-08 17:00:45 +00001610- Buffer objects, at the C level, never used the char buffer
1611 implementation even when the char buffer for the wrapped object was
1612 explicitly requested (originally returned the read or write buffer).
1613 Now a TypeError is raised if the char buffer is not present but is
1614 requested.
1615
Georg Brandlddbaa662006-06-04 21:56:52 +00001616- Patch #1346214: Statements like "if 0: suite" are now again optimized
1617 away like they were in Python 2.4.
1618
Georg Brandlb7c8f542006-05-27 12:30:25 +00001619- Builtin exceptions are now full-blown new-style classes instead of
1620 instances pretending to be classes, which speeds up exception handling
1621 by about 80% in comparison to 2.5a2.
1622
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001623- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1624 Unicode 4.1.
1625
Georg Brandlf4ef1162006-05-26 18:03:31 +00001626- Patch #921466: sys.path_importer_cache is now used to cache valid and
1627 invalid file paths for the built-in import machinery which leads to
1628 fewer open calls on startup.
1629
Tim Peters696cf432006-05-24 21:10:40 +00001630- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1631 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1632 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1633 the number of input digits (it was and remains linear-time for bases
1634 2, 4, 8, 16 and 32).
1635
Tim Petersb713ec22006-05-23 18:45:30 +00001636- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1637 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1638 an integer close to ``sys.maxint``. This was repaired by patch
1639 #1335972, which also gives a nice speedup.
1640
Richard Jonescebbefc2006-05-23 18:28:17 +00001641- Patch #1337051: reduced size of frame objects.
1642
1643- PyErr_NewException now accepts a tuple of base classes as its
1644 "base" parameter.
1645
Richard Jones7c88dcc2006-05-23 10:37:38 +00001646- Patch #876206: function call speedup by retaining allocated frame
1647 objects.
1648
Georg Brandl7b90e162006-05-18 07:01:27 +00001649- Bug #1462152: file() now checks more thoroughly for invalid mode
1650 strings and removes a possible "U" before passing the mode to the
1651 C library function.
1652
Neal Norwitz1004a532006-05-15 07:17:23 +00001653- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1654
Neal Norwitz373f0a72006-05-15 07:04:36 +00001655- Bug #1487966: Fix SystemError with conditional expression in assignment
1656
Martin v. Löwis879768d2006-05-11 13:28:43 +00001657- WindowsError now has two error code attributes: errno, which carries
1658 the error values from errno.h, and winerror, which carries the error
1659 values from winerror.h. Previous versions put the winerror.h values
1660 (from GetLastError()) into the errno attribute.
1661
Martin v. Löwis77736712006-05-04 05:51:03 +00001662- Patch #1475845: Raise IndentationError for unexpected indent.
1663
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001664- Patch #1479181: split open() and file() from being aliases for each other.
1665
Tim Peters44bd9862006-06-01 13:49:23 +00001666- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1667 methods were always silently ignored by dictionaries when comparing keys.
1668 They are now passed through (except when using the C API function
1669 ``PyDict_GetItem()``, whose semantics did not change).
1670
1671- Bug #1456209: In some obscure cases it was possible for a class with a
1672 custom ``__eq__()`` method to confuse dict internals when class instances
1673 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1674 No, you don't have any code that did this ;-)

1682
Brett Cannon6ee7d012006-06-08 16:23:04 +00001683- Change binascii.hexlify to accept a read-only buffer instead of only a char
1684 buffer and actually follow its documentation.
1685
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001686- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1687
Nick Coghlanc649ec52006-05-29 12:43:05 +00001688- Patch #1478788 (modified version): The functional extension module has
1689 been renamed to _functools and a functools Python wrapper module added.
1690 This provides a home for additional function related utilities that are
1691 not specifically about functional programming. See PEP 309.
1692
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001693- Patch #1493701: performance enhancements for struct module.

1701 enabled builds on Windows and systems with Posix threads support.
1702
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001703- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1704 (up to the system limit of 32K characters).
1705
1706- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1707 As a result, these functions now raise WindowsError instead of OSError.
1708
Tim Peters7a822da2006-05-25 21:50:17 +00001709- ``time.clock()`` on Win64 should use the high-performance Windows
1710 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1711 Windows platforms).
1712
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001713- Calling Tk_Init twice is refused if the first call failed as that
1714 may deadlock.
1715
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001716- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1717 accept it without potentially using an uninitialized pointer.
1718
1719- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1720 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1730 results. It could previously incorrectly return 0 in some cases.
1731 Fixes SF bug 1493322 (pybsddb bug 1184012).
1732
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001733- bsddb: the bsddb.dbtables Modify method now raises the proper error and

1735 Fixes SF python patch/bug #1408584.
1736
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001737- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001738 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001739 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1740 database calls that would previously deadlock. [SF python bug #775414]

Georg Brandl83cc0d02006-06-14 08:50:03 +00001763- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1764 mime.types file for determining MIME types.
1765
Georg Brandl2605ca82006-06-14 06:08:31 +00001766- Bug #1339007: Shelf objects now don't raise an exception in their
1767 __del__ method when initialization failed.
1768
Martin v. Löwisd8251432006-06-14 05:21:04 +00001769- Patch #1455898: The MBCS codec now supports the incremental mode for
1770 double-byte encodings.
1771
Tim Peters43898b42006-06-14 04:09:25 +00001772- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1773 guarantee that adjacent triples in the return list always describe
1774 non-adjacent blocks. Previously, a pair of matching blocks could end
1775 up being described by multiple adjacent triples that formed a partition
1776 of the matching pair.
1777
Greg Ward0e0c9f42006-06-11 16:24:11 +00001778- Bug #1498146: fix optparse to handle Unicode strings in option help,
1779 description, and epilog.
1780
Greg Wardd1c797e2006-06-11 14:42:41 +00001781- Bug #1366250: minor optparse documentation error.
1782
Greg Ward7f547402006-06-11 00:40:49 +00001783- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1784 clarify docs.
1785
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001786- The wsgiref package has been added to the standard library.
1787
Nick Coghlan676725d2006-06-08 13:54:49 +00001788- The functions update_wrapper() and wraps() have been added to the functools
1789 module. These make it easier to copy relevant metadata from the original
1790 function when writing wrapper functions.
1791
Tim Petersd6a9eef2006-06-05 01:48:21 +00001792- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1793 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001794
Martin v. Löwis3f767792006-06-04 19:36:28 +00001795- Patch #1359618: Speed up charmap encoder by using a trie structure
1796 for lookup.
1797
Tim Petersd609b1a2006-06-02 23:22:51 +00001798- The functions in the ``pprint`` module now sort dictionaries by key
1799 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1800 if and only if its display required more than one line, although that
1801 wasn't documented. The new behavior increases predictability; e.g.,
1802 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1803
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001804- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1805 (thanks for J. J. Lee).
1806
Georg Brandl2b330372006-05-28 20:23:12 +00001807- Patch #1496206: improve urllib2 handling of passwords with respect to
1808 default HTTP and HTTPS ports.
1809
George Yoshidaf3c65de2006-05-28 16:39:09 +00001810- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1811
Bob Ippolito7298f272006-05-23 18:43:47 +00001812- Patch #1281707: speed up gzip.readline.
1813
Georg Brandlb89316f2006-05-17 15:51:16 +00001814- Patch #1180296: Two new functions were added to the locale module:
1815 format_string() to get the effect of "format % items" but locale-aware,
1816 and currency() to format a monetary number with currency sign.
1817
Georg Brandle3a25832006-05-17 14:56:04 +00001818- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1819 and several features added, such as speed and geometry control.
1820
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001821- Patch #1488881: add support for external file objects in bz2 compressed
1822 tarfiles.
1823
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001824- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1825 stdout arguments, making it possible to redirect input and output
1826 for remote debugging.
1827
1828- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1829 a couple of issues, notably handling of long file names using the
1830 GNU LONGNAME extension.
1831
1832- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1833 new flag when ``name`` is already the name of an option flag.
1834
1835- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1836 package.
1837
1838- Patch #1472854: make the rlcompleter.Completer class usable on non-
1839 UNIX platforms.
1840
1841- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1842
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001843- Bug #1472827: correctly escape newlines and tabs in attribute values in
1844 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001874What's New in Python 2.5 alpha 2?
1875=================================
1876
1877*Release date: 27-APR-2006*
1878
1879Core and builtins
1880-----------------
1881
Thomas Heller1b046642006-04-18 18:51:06 +00001882- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1883 by converting these apis from macros into exported functions again:
1884
1885 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1886 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1887 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1888 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1889 PyRun_String Py_CompileString
1890
Martin v. Löwis45294a92006-04-18 06:24:08 +00001891- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1892
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001893- All uses of PyStructSequence_InitType have been changed to initialize
1894 the type objects only once, even if the interpreter is initialized
1895 multiple times.
1896
Neal Norwitz61546162006-04-14 05:20:28 +00001897- Bug #1454485, array.array('u') could crash the interpreter. This was
1898 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1899 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1900
1901- Py_UNICODE is unsigned. It was always documented as unsigned, but
1902 due to a bug had a signed value in previous versions.
1903
Tim Peters3a5e8b12006-04-11 01:44:07 +00001904- Patch #837242: ``id()`` of any Python object always gives a positive
1905 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1906 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001907 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001908 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001909
Tim Peters3a5e8b12006-04-11 01:44:07 +00001910 def __hash__(self):
1911 return id(self) # WRONG
1912
1913 because a hash result must be a (short) Python int but it was always
1914 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001915 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001916 was always usable as a hash value before this patch. That's no longer
1917 necessarily so.
1918
1919- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001920 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001921 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001922 #1454844)
1923
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001924- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1925 involving generators that have paused outside of any ``try`` or ``with``
1926 blocks. (In 2.5a1, a paused generator that was part of a reference
1927 cycle could not be garbage collected, regardless of whether it was
1928 paused in a ``try`` or ``with`` block.)

1935
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001936- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1937 fails with an error condition.
1938
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001939- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1940
1941- Bug #1117761: bsddb.*open() no longer raises an exception when using
1942 the cachesize parameter.
1943
1944- Bug #1149413: bsddb.*open() no longer raises an exception when using
1945 a temporary db (file=None) with the 'n' flag to truncate on open.
1946
1947- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1948 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001949
Armin Rigoa9017c32006-04-19 11:50:27 +00001950- Patch #1062014: AF_UNIX sockets under Linux have a special
1951 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +00001956- Bug #1223937: subprocess.CalledProcessError reports the exit status
1957 of the process using the returncode attribute, instead of
1958 abusing errno.
1959
Tim Peters711bf302006-04-25 03:31:36 +00001960- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1961 a doctest to be skipped (the code is not run, and the expected output
1962 or exception is ignored).
1963
Nick Coghlanda2268f2006-04-24 04:37:15 +00001964- Fixed contextlib.nested to cope with exceptions being raised and
1965 caught inside exit handlers.
1966
Greg Wardab05edc2006-04-23 03:47:58 +00001967- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1968 hex, octal, or binary; add ``append_const`` action; keep going if
1969 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1970 added ``epilog`` for better help generation).
1971
Tim Peters21fbd572006-04-21 21:18:10 +00001972- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1973 called from a thread spawned as a side effect of importing a module.
1974
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001975- The pydoc module now supports documenting packages contained in
1976 .zip or .egg files.
1977
1978- The pkgutil module now has several new utility functions, such
1979 as ``walk_packages()`` to support working with packages that are either
1980 in the filesystem or zip files.
1981
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001982- The mailbox module can now modify and delete messages from
1983 mailboxes, in addition to simply reading them. Thanks to Gregory
1984 K. Johnson for writing the code, and to the 2005 Google Summer of
1985 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001986
Tim Petersc7605f22006-04-17 21:12:33 +00001987- The ``__del__`` method of class ``local`` in module ``_threading_local``
1988 returned before accomplishing any of its intended cleanup.
1989
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001990- Patch #790710: Add breakpoint command lists in pdb.

1995
Anthony Baxtere29002c2006-04-12 12:07:31 +00001996- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1997 Windows. Bug #1469163.
1998
Phillip J. Eby47032112006-04-11 01:07:43 +00001999- The warnings, linecache, inspect, traceback, site, and doctest modules
2000 were updated to work correctly with modules imported from zipfiles or
2001 via other PEP 302 __loader__ objects.
2002
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002003- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis4be4e652006-04-17 19:25:49 +00002016- The Makefile now has a reindent target, which runs reindent.py on
2017 the library.
2018

2024 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002025 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002026 CXX from --with-cxx-main, see description in README.
2027

2031
Tim Peters8931ff12006-05-13 23:28:20 +00002032- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2033 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2034 and "%zu" for unsigned integers of type ``size_t``.
2035
Anthony Baxter51bcb682006-04-05 14:51:42 +00002036Tests
2037-----
2038
Nick Coghlanda2268f2006-04-24 04:37:15 +00002039- test_contextlib now checks contextlib.nested can cope with exceptions
2040 being raised and caught inside exit handlers.
2041
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002042- test_cmd_line now checks operation of the -m and -c command switches
2043
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002044- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2045 it separately and by hand. It also wasn't cleaning up its changes to
2046 the current Decimal context.
2047
Thomas Woutersabd08882006-04-26 15:53:30 +00002048- regrtest.py now has a -M option to run tests that test the new limits of
2049 containers, on 64-bit architectures. Running these tests is only sensible
2050 on 64-bit machines with more than two gigabytes of memory. The argument
2051 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002077Core and builtins
2078-----------------
2079
Nick Coghlan43832302006-04-23 17:04:07 +00002080- PEP 338: -m command line switch now delegates to runpy.run_module
2081 allowing it to support modules in packages and zipfiles
2082
Martin v. Löwisc661b882006-04-20 04:54:23 +00002083- On Windows, .DLL is not an accepted file name extension for
2084 extension modules anymore; extensions are only found if they
2085 end in .PYD.
2086
Martin v. Löwisea62d252006-04-03 10:56:49 +00002087- Bug #1421664: sys.stderr.encoding is now set to the same value as
2088 sys.stdout.encoding.
2089
Neal Norwitz92e212f2006-04-03 04:48:37 +00002090- __import__ accepts keyword arguments.
2091
Georg Brandlccadf842006-03-31 18:54:53 +00002092- Patch #1460496: round() now accepts keyword arguments.
2093
Anthony Baxter262c00a2006-03-30 10:53:17 +00002094- Fixed bug #1459029 - unicode reprs were double-escaped.
2095
Hye-Shik Changd478f342006-03-23 12:32:36 +00002096- Patch #1396919: The system scope threads are reenabled on FreeBSD
2097 5.4 and later versions.
2098
Neal Norwitze98ccf62006-03-23 05:39:47 +00002099- Bug #1115379: Compiling a Unicode string with an encoding declaration
2100 now gives a SyntaxError.
2101
Georg Brandlabd1ff82006-03-18 07:59:59 +00002102- Previously, Python code had no easy way to access the contents of a
2103 cell object. Now, a ``cell_contents`` attribute has been added
2104 (closes patch #1170323).
2105
Tim Peterscf79aac2006-03-16 01:14:46 +00002106- Patch #1123430: Python's small-object allocator now returns an arena to
2107 the system ``free()`` when all memory within an arena becomes unused
2108 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2109 freed. Some applications will see a drop in virtual memory size now,
2110 especially long-running applications that, from time to time, temporarily
2111 use a large number of small objects. Note that when Python returns an
2112 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002113 platform C library will in turn return that memory to the operating system.
2114 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002115 appears to be effective at least on Microsoft C and gcc-based systems.
2116 Thanks to Evan Jones for hard work and patience.
2117
Georg Brandl533ff6f2006-03-08 18:09:27 +00002118- Patch #1434038: property() now uses the getter's docstring if there is
2119 no "doc" argument given. This makes it possible to legitimately use
2120 property() as a decorator to produce a read-only property.
2121
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002122- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2123 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2124 of requiring an int or long in slicing and a few other contexts, enabling
2125 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2126
Neal Norwitz995acdf2006-03-07 05:01:00 +00002127- Fixed various bugs reported by Coverity's Prevent tool.
2128
Brett Cannonbf364092006-03-01 04:25:17 +00002129- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2130 new exception base class, BaseException, which has a new message attribute.
2131 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2132 Raising a string exception now raises a DeprecationWarning.
2133
Thomas Woutersfb609f42006-02-28 16:37:25 +00002134- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2135 explicitly relative, using 'from .module import name' to mean 'from the same
2136 package as this module is in. Imports without dots still default to the
2137 old relative-then-absolute, unless 'from __future__ import
2138 absolute_import' is used.
2139
Brett Cannona7446e32006-02-27 23:39:10 +00002140- Properly check if 'warnings' raises an exception (usually when a filter set
2141 to "error" is triggered) when raising a warning for raising string
2142 exceptions.
2143
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002144- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002145 The name was removed from Include/code.h.
2146
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002147- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002148
Guido van Rossum1968ad32006-02-25 22:38:04 +00002149- Patch 1433928:
2150 - The copy module now "copies" function objects (as atomic objects).
2151 - dict.__getitem__ now looks for a __missing__ hook before raising
2152 KeyError.
2153
Tim Peters84ef21c2006-02-28 20:39:06 +00002154- PEP 343: with statement implemented. Needs ``from __future__ import
2155 with_statement``. Use of 'with' as a variable will generate a warning.
2156 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002157 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002158 The following objects have __context__ methods:
2159 - The built-in file type.
2160 - The thread.LockType type.
2161 - The following types defined by the threading module:
2162 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2163 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002164
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002165- Fix the encodings package codec search function to only search
2166 inside its own package. Fixes problem reported in patch #1433198.
2167
2168 Note: Codec packages should implement and register their own
2169 codec search function. PEP 100 has the details.
2170
Tim Peters9ea89d22006-06-04 03:26:02 +00002171- PEP 353: Using ``Py_ssize_t`` as the index type.
2172
2173- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2174 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2175 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2176 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2177 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002178
Neal Norwitzfc76d632006-01-10 06:03:13 +00002179- Patch #1400181, fix unicode string formatting to not use the locale.
2180 This is how string objects work. u'%f' could use , instead of .
2181 for the decimal point. Now both strings and unicode always use periods.
2182
Neal Norwitz671b9e32006-01-09 07:07:12 +00002183- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2184 configure would break checking curses.h.
2185
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002186- Bug #959576: The pwd module is now builtin. This allows Python to be
2187 built on UNIX platforms without $HOME set.
2188
Neal Norwitzc10978f2005-12-19 06:07:16 +00002189- Bug #1072182, fix some potential problems if characters are signed.
2190
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002191- Bug #889500, fix line number on SyntaxWarning for global declarations.
2192
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002193- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2194
Neal Norwitze7214a12005-12-18 05:03:17 +00002195- Support for converting hex strings to floats no longer works.
2196 This was not portable. float('0x3') now raises a ValueError.
2197
Barry Warsaw2a38a862005-12-18 01:27:35 +00002198- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002199 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002200 is now displayed in interactive prompt banner.
2201
Georg Brandlfa166682005-12-17 21:45:17 +00002202- Implementation of PEP 341 - Unification of try/except and try/finally.
2203 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002204 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002205
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002206- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2207 now encodes backslash correctly.
2208
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002209- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2210
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002211- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002212 and long longs.
2213
Neal Norwitz67715f02005-11-09 06:59:35 +00002214- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002215 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002216 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002217
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002218- Replaced most Unicode charmap codecs with new ones using the
2219 new Unicode translate string feature in the builtin charmap
2220 codec; the codecs were created from the mapping tables available
2221 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2222 encodings now include a mapping for the Apple logo)
2223
Tim Peterse3547fd2005-12-16 23:13:57 +00002224- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002225
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002226- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002227
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002228- A new AST parser implementation was completed. The abstract
2229 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002230 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002231
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002232- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002233 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2234
Neal Norwitz708e51a2005-10-03 04:48:15 +00002235- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2236
Neal Norwitz11bd1192005-10-03 00:54:56 +00002237- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2238 Provide a warning when a directory is passed on the command line.
2239
Neal Norwitz40d37812005-10-02 01:48:49 +00002240- Fix segfault with invalid coding.
2241
2242- SF bug #772896: unknown encoding results in MemoryError.
2243
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002244- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002245 supported a __len__() method which evaluated to False when the iterator
2246 was empty.
2247
Guido van Rossum630db602005-09-20 18:49:54 +00002248- On 64-bit platforms, when __len__() returns a value that cannot be
2249 represented as a C int, raise OverflowError.
2250
Skip Montanarof8948ca2005-09-19 03:54:46 +00002251- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002252 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002253
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002254- SF bug #893549: parsing keyword arguments was broken with a few format
2255 codes.
2256
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002257- Changes donated by Elemental Security to make it work on AIX 5.3
2258 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2259 bug #105470: test_pwd fails on 64bit system (Opteron).
2260
Guido van Rossum539c6622005-09-14 17:49:54 +00002261- Changes donated by Elemental Security to make it work on HP-UX 11 on
2262 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2263
Georg Brandl4550b8d2005-08-26 06:43:52 +00002264- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002265 (fixes bug #1119418).
2266
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002267- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2268
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002269- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2270 exceptions that cause a function to exit.
2271
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002272- The implementation of set() and frozenset() was revised to use its
2273 own internal data structure. Memory consumption is reduced by 1/3
2274 and there are modest speed-ups as well. The API is unchanged.
2275
Tim Petersde7990b2005-07-17 23:45:23 +00002276- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2277
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002278- SF bug #1229429: PyObject_CallMethod failed to decrement some
2279 reference counts in some error exit cases.
2280
Tim Petersecc6e6a2005-07-10 22:30:55 +00002281- SF bug #1185883: Python's small-object memory allocator took over
2282 a block managed by the platform C library whenever a realloc specified
2283 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002284 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002285 portable way to copy data from the C-managed block into Python's
2286 small-object space without risking a memory fault. Python's small-object
2287 realloc now leaves such blocks under the control of the platform C
2288 realloc.
2289
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002290- SF bug #1232517: An overflow error was not detected properly when
2291 attempting to convert a large float to an int in os.utime().
2292
Raymond Hettinger3296e692005-06-29 23:29:56 +00002293- SF bug #1224347: hex longs now print with lowercase letters just
2294 like their int counterparts.
2295
Michael W. Hudson188d4362005-06-20 16:52:57 +00002296- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2297 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2298 interpreter states; back out that fix and do a better job (see
2299 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2300 for a longer write-up of the problem).
2301
Michael W. Hudsondf888462005-06-03 14:41:55 +00002302- SF patch #1180995: marshal now uses a binary format by default when
2303 serializing floats.
2304
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002305- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2306 the routines that promise to produce IEEE 754 binary representations
2307 of floats now simply copy bytes around.
2308
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002309- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2310 278.
2311
Brett Cannonc3647ac2005-04-26 03:45:26 +00002312- patch #1109424: int, long, float, complex, and unicode now check for the
2313 proper magic slot for type conversions when subclassed. Previously the
2314 magic slot was ignored during conversion. Semantics now match the way
2315 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002316 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002317 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002318 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002319
Barry Warsawc8d907c2005-04-19 23:43:40 +00002320- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2321 NULL, now raise an AttributeError when attempting to set or delete the
2322 attribute. Previously a TypeError was raised, but this was inconsistent
2323 with the equivalent pure-Python implementation.
2324
Michael W. Hudson774479c2005-04-18 08:46:17 +00002325- It is now safe to call PyGILState_Release() before
2326 PyEval_InitThreads() (note that if there is reason to believe there
2327 are multiple threads around you still must call PyEval_InitThreads()
2328 before using the Python API; this fix is for extension modules that
2329 have no way of knowing if Python is multi-threaded yet).
2330
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002331- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2332 disabled caused a crash.
2333
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002334- Bug #1165306: instancemethod_new allowed the creation of a method
2335 with im_class == im_self == NULL, which caused a crash when called.
2336
Tim Petersecc6e6a2005-07-10 22:30:55 +00002337- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002338 fixes the crash seen in bug #1165761
2339

2379 unicode instance if the argument is not an instance of basestring and
2380 calling __str__ on the argument returns a unicode instance.
2381
Tim Petersf4e69282006-02-27 17:15:31 +00002382- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2383 current thread state when the auto-GIL-state machinery knows about
2384 it (since the thread state is being deleted, continuing to remember it
2385 can't help, but can hurt if another thread happens to get created with
2386 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00002582- PEP 338: new module runpy defines a run_module function to support
2583 executing modules which provide access to source code or a code object
2584 via the PEP 302 import mechanisms.

2594 in attribute values.
2595
Anthony Baxterc51ee692006-04-01 00:57:31 +00002596- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002597 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002598 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002599 module will not be built.
2600
Tim Petersc17976e2006-04-01 00:26:53 +00002601- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2602 aren't officially supported here, and trying to use them will probably
2603 raise an exception some day. But dicts have been allowed, and "mostly

2624
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002625- email 4.0 package now integrated. This is largely the same as the email 3.0
2626 package that was included in Python 2.3, except that PEP 8 module names are
2627 now used (e.g. mail.message instead of email.Message). The MIME classes
2628 have been moved to a subpackage (e.g. email.mime.text instead of
2629 email.MIMEText). The old names are still supported for now. Several
2630 deprecated Message methods have been removed and lots of bugs have been
2631 fixed. More details can be found in the email package documentation.
2632

2634 (a subclass of tuple) that provides incremental decoders and encoders
2635 (a way to use stateful codecs without the stream API). Python functions
2636 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2637 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2638 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002639

2641 a ValueError instead of a StopIteration now (like file and cString.String do).
2642 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2643 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002717 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2718 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2719 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2720 Ronald L. Rivest offered this advice for Python:
2721
2722 "The consensus of researchers in this area (at least as
2723 expressed at the NIST Hash Function Workshop 10/31/05),
2724 is that SHA-256 is a good choice for the time being, but
2725 that research should continue, and other alternatives may
2726 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002727
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002728- Added a subset of Fredrik Lundh's ElementTree package. Available

2884
Raymond Hettingerbab41432005-02-05 01:31:19 +00002885- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2886
Guido van Rossumd0641422005-02-03 15:01:24 +00002887- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2888 disables recursive traversal through instance attributes, which can
2889 be exploited in various ways.
2890
Tim Peterse3547fd2005-12-16 23:13:57 +00002891- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002892 flags on the HTTP listening socket.
2893
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002894- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2895 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2896
Fred Drakefbdeaad2006-07-29 16:56:15 +00002897- Patches #893642, #1039083: add allow_none, encoding arguments to
2898 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002899

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002902- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2903
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002904- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2905
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002906- Enhancements to the csv module:
2907
2908 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002909 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002910 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002911 + Dialect parameter parsing has been re-implemented to improve error
2912 reporting.
2913 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2914 dictates.
2915 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002916 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002917 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002918 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2919 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002920 + reader now allows \r characters to be quoted (previously it only allowed
2921 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002922 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002923 + Dialect classes passed to the module are no longer instantiated by
2924 the module before being parsed (the former validation scheme required
2925 this, but the mechanism was unreliable).
2926 + The dialect registry now contains instances of the internal
2927 C-coded dialect type, rather than references to python objects.
2928 + the internal c-coded dialect type is now immutable.
2929 + register_dialect now accepts the same keyword dialect specifications
2930 as the reader and writer, allowing the user to register dialects
2931 without first creating a dialect class.
2932 + a configurable limit to the size of parsed fields has been added -
2933 previously, an unmatched quote character could result in the entire
2934 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002935 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002936 the parser field size limit (returning the former limit). The initial
2937 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002938 + A line_num attribute has been added to the reader object, which tracks
2939 the number of lines read from the source iterator. This is not
2940 the same as the number of records returned, as records can span
2941 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002942 + reader and writer objects were not being registered with the cyclic-GC.
2943 This has been fixed.
2944
Brett Cannone6539c42005-01-08 02:43:53 +00002945- _DummyThread objects in the threading module now delete self.__block that is
2946 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2947 lock primitives tend to be limited in number and thus should not be wasted on
2948 a _DummyThread object. Fixes bug #1089632.
2949
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002950- The imghdr module now detects Exif files.
2951
Raymond Hettinger6065d322004-12-20 23:51:53 +00002952- StringIO.truncate() now correctly adjusts the size attribute.
2953 (Bug #951915).
2954
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002955- locale.py now uses an updated locale alias table (built using
2956 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2957 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002958 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002959
Raymond Hettinger3557f422004-12-07 12:02:02 +00002960- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2961
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002962- the pickle module no longer accepts the deprecated None option in the
2963 args tuple returned by __reduce__().
2964
Brett Cannon84667c02004-12-07 03:25:18 +00002965- optparse now optionally imports gettext. This allows its use in setup.py.
2966
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002967- the pickle module no longer uses the deprecated bin parameter.
2968
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002969- the shelve module no longer uses the deprecated binary parameter.
2970
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002971- the pstats module no longer uses the deprecated ignore() method.
2972
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002973- the filecmp module no longer uses the deprecated use_statcache argument.
2974
Raymond Hettinger664347b2004-12-04 21:21:53 +00002975- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2976 extended or overridden by subclasses. Formerly, the subclassed method would
2977 be ignored by the rest of the module. (Bug #1078905).
2978
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002979- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002980 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002981
Walter Dörwald36733692004-12-22 12:50:50 +00002982- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2983 once when a size argument is given. This prevents a buffer overflow in the
2984 tokenizer with very long source lines.
2985
Barry Warsaw538561e2006-01-01 21:48:54 +00002986- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2987 immediately after creating the object, without any intervening
2988 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002989
Skip Montanaro05885812005-01-16 20:48:27 +00002990- The reconvert.quote function can now emit triple-quoted strings. The
2991 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002992
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002993- ``UserString.MutableString`` now supports negative indices in
2994 ``__setitem__`` and ``__delitem__``
2995
Greg Ward40407942005-03-05 02:53:17 +00002996- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2997 correctly.
2998
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002999- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3000 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3001 character even if the user has passed a size parameter to get a proper
3002 line ending. Remove the special handling of a "\r\n" that has been split
3003 between two lines.
3004
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003005- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3006 about illegal code points. The codec now supports PEP 293 style error
3007 handlers.
3008
Walter Dörwald78a78b02005-09-01 12:04:29 +00003009- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003010 from the input stream, so that the output is a byte string in the correct
3011 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003012
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003013- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3014 considering it exactly like a '*'.
3015
Walter Dörwald007f8df2005-10-09 19:42:27 +00003016- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3017 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003018
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003019- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3020
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003021- Patch #1413711: Certain patterns of differences were making difflib
3022 touch the recursion limit.
3023
Walter Dörwald58917a62006-03-31 15:26:22 +00003024- Bug #947906: An object oriented interface has been added to the calendar
3025 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003026 called as a script (e.g. via ``python -mcalendar``). Localized month and
3027 weekday names can be ouput (even if an exotic encoding is used) using
3028 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003029
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003030Build

3032
Neal Norwitz602d3392006-03-31 08:21:40 +00003033- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3034 by using -mieee gcc option.
3035

3037
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003038- Build support for Win64-AMD64 was added.
3039
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003040- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3041
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003042- Patch #881820: look for openpty and forkpty also in libbsd.
3043
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003044- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3045 The zlib module is now builtin on Windows.
3046
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003047- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3048
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003049- Bug #1189330: configure did not correctly determine the necessary
3050 value of LINKCC if python was built with GCC 4.0.
3051
Trent Mick8321b422005-07-26 02:29:21 +00003052- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3053 vulnerability in zlib 1.2.1 and 1.2.2.
3054
Brett Cannon08cd5982005-04-24 22:26:38 +00003055- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3056 flags that change binary compatibility. Changes were also made to
3057 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003058 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003059
Bob Ippolitoed233462005-03-29 13:47:59 +00003060- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3061 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3062 no longer exists). This configure patch makes things right.
3063
Martin v. Löwise2713be2005-03-08 15:03:08 +00003064- Bug #1158607: Build with --disable-unicode again.
3065
Brett Cannon46d96232005-02-16 00:07:19 +00003066- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3067 defined. Discovered as a result of not being able to build on OS X.
3068
Brett Cannon516592f2004-12-07 00:42:59 +00003069- setup.py now uses the directories specified in LDFLAGS using the -L option
3070 and in CPPFLAGS using the -I option for adding library and include
3071 directories, respectively, for compiling extension modules against. This has
3072 led to the core being compiled using the values in CPPFLAGS. It also removes
3073 the need for the special-casing of both DarwinPorts and Fink for darwin since
3074 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3075 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3076 Fink, ``-I/opt/local/include`` for DarwinPorts).
3077
Brett Cannon43802422005-02-10 20:48:03 +00003078- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3079 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3080 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3081 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003083C API
3084-----
3085
Tim Petersc9d78aa2006-03-26 23:27:58 +00003086- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3087 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3088 is obtained via the ``PyObject_`` family, it must be released via the
3089 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3090 always been officially true, but when Python's small-object allocator was
3091 introduced, an attempt was made to cater to a few extension modules
3092 discovered at the time that obtained memory via ``PyObject_New`` but
3093 released it via ``PyMem_DEL``. It's years later, and if such code still
3094 exists it will fail now (probably with segfaults, but calling wrong
3095 low-level memory management functions can yield many symptoms).
3096
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003097- Added a C API for set and frozenset objects.
3098
Raymond Hettinger66517482004-12-03 11:45:13 +00003099- Removed PyRange_New().
3100
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003101- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3102 mapping argument now. This string is used as a mapping table. Byte values
3103 greater than the length of the string and 0xFFFE are treated as undefined
3104 mappings.
