904
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000905- Bug #1520864: unpacking singleton tuples in list comprehensions and
906 generator expressions (x for x, in ... ) works again. Fixing this problem
907 required changing the .pyc magic number. This means that .pyc files
908 generated before 2.5c2 will be regenerated.

1020Core and builtins
1021-----------------
1022
Neal Norwitz24b6f202006-09-05 04:43:56 +00001023- Fix infinite recursion when subclassing long and overriding __hash__.
1024
1025- Fix concatenation (+=) of long strings.
1026
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001027- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001028 compared equal or unequal to a string and a UnicodeDecodeError
1029 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001030
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001031 Instead, the equal (==) and unequal (!=) comparison operators will
1032 now issue a UnicodeWarning and interpret the two objects as
1033 unequal. The UnicodeWarning can be filtered as desired using
1034 the warning framework, e.g. silenced completely, turned into an
1035 exception, logged, etc.
1036
1037 Note that compare operators other than equal and unequal will still
1038 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001039
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001040- Fix segfault when doing string formatting on subclasses of long.
1041
1042- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1043 with new-style classes.
1044
1045- Fix bug related to __len__ functions returning negative values with
1046 classic classes.
1047
1048- Patch #1538606, Fix __index__() clipping. There were some problems
1049 discovered with the API and how integers that didn't fit into Py_ssize_t
1050 were handled. This patch attempts to provide enough alternatives
1051 to effectively use __index__.
1052
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001053- Bug #1536021: __hash__ may now return long int; the final hash
1054 value is obtained by invoking hash on the long int.
1055
Thomas Hellerab1049c2006-08-08 17:37:00 +00001056- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1057
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001058- Bug #1535165: fixed a segfault in input() and raw_input() when
1059 sys.stdin is closed.
1060
Thomas Heller74d36f02006-08-04 18:17:40 +00001061- On Windows, the PyErr_Warn function is now exported from
1062 the Python dll again.
1063
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001064- Bug #1191458: tracing over for loops now produces a line event
1065 on each iteration. Fixing this problem required changing the .pyc
1066 magic number. This means that .pyc files generated before 2.5c1
1067 will be regenerated.
1068
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001069- Bug #1333982: string/number constants were inappropriately stored
1070 in the byte code and co_consts even if they were not used, ie
1071 immediately popped off the stack.
1072
Georg Brandle9462c72006-08-04 18:03:37 +00001073- Fixed a reference-counting problem in property().

1077-------
1078
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001079- Fix a bug in the ``compiler`` package that caused invalid code to be
1080 generated for generator expressions.
1081
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001082- The distutils version has been changed to 2.5.0. The change to
1083 keep it programmatically in sync with the Python version running
1084 the code (introduced in 2.5b3) has been reverted. It will continue
1085 to be maintained manually as static string literal.
1086
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001087- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001088 and this cannot be converted to the required C type, an exception is
1089 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001090 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001091
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001092- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001093 an exception.
1094
Tim Peterscbdd3502006-09-05 01:47:53 +00001095- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001096 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001097 workarounds for clocks with low resolution, to stop the code yielding
1098 duplicate UUIDs.
1099
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001100- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1101 before raising SystemExit, allowing IDLE to honor quit() and exit().
1102
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001103- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1104
Georg Brandl7a1af772006-08-14 21:55:28 +00001105- Patch #1536071: trace.py should now find the full module name of a
1106 file correctly even on Windows.
1107
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001108- logging's atexit hook now runs even if the rest of the module has
1109 already been cleaned up.
1110
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001111- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001112
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001113- Bug #1531405, format_exception no longer raises an exception if
1114 str(exception) raised an exception.
1115
Neil Schemenauer06ded092006-08-04 16:20:30 +00001116- Fix a bug in the ``compiler`` package that caused invalid code to be
1117 generated for nested functions.

1134 uses the _as_parameter_ attribute when objects are passed to foreign
1135 function calls. The ctypes version number was changed to 1.0.1.
1136
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001137- Bug #1530559, struct.pack raises TypeError where it used to convert.

Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001195- Bug #1515471: string.replace() accepts character buffers again.
1196
Neal Norwitz07aadb12006-07-30 06:55:48 +00001197- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1198 This provides the proper warning for struct.pack().
1199 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1200
Neal Norwitz0d62a062006-07-30 06:53:31 +00001201- Patch #1531113: Fix augmented assignment with yield expressions.
1202 Also fix a SystemError when trying to assign to yield expressions.
1203
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001204- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1205 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1206 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1207 excessive filesystem operations during imports.
1208
Tim Petersbc24eee2006-07-27 01:14:53 +00001209- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1210 operations on signed longs that are formally undefined by C.
1211 Unfortunately, at least one compiler now cares about that, so complicated
1212 the code to make that compiler happy again.
1213
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001214- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1215
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001216- Patch #1232023: Stop including current directory in search
1217 path on Windows.
1218
Neal Norwitze1fdb322006-07-21 05:32:28 +00001219- Fix some potential crashes found with failmalloc.
1220
Neal Norwitze7563102006-07-17 01:00:16 +00001221- Fix warnings reported by Klocwork's static analysis tool.
1222
Neal Norwitz84be93b2006-07-16 01:50:38 +00001223- Bug #1512814, Fix incorrect lineno's when code within a function
1224 had more than 255 blank lines.
1225
Georg Brandl9dceedb2006-07-12 15:31:17 +00001226- Patch #1521179: Python now accepts the standard options ``--help`` and
1227 ``--version`` as well as ``/?`` on Windows.
1228
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001229- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001230 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001231 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001232
Tim Peters112aad32006-07-19 00:03:19 +00001233- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001234 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001235 new ``sys._current_frames()`` returns a dictionary with one entry,
1236 mapping the faux "thread id" 0 to the current frame.
1237
Ronald Oussoren3075e162006-07-25 20:28:55 +00001238- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001239

1242-------
1243
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001244- Correction of patch #1455898: In the mbcs decoder, set final=False
1245 for stream decoder, but final=True for the decode function.
1246
Georg Brandl07fec3a2006-08-01 18:49:24 +00001247- os.urandom no longer masks unrelated exceptions like SystemExit or
1248 KeyboardInterrupt.
1249
Tim Peters4643c2f2006-08-10 22:45:34 +00001250- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001251 shutil.copytree on Windows
1252
Georg Brandle34ac7c2006-07-30 11:07:23 +00001253- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1254 refers to file descriptors, not file objects.
1255
Tim Peterscbdd3502006-09-05 01:47:53 +00001256- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001257 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001258 #1513611, and probably others.
1259
Georg Brandledd9b0d2006-07-29 09:33:26 +00001260- Bug #1441397: The compiler module now recognizes module and function
1261 docstrings correctly as it did in Python 2.4.
1262
Tim Peters6f681472006-07-27 23:44:37 +00001263- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1264 lost that tests are sorted by name before being run. This rarely
1265 matters for well-written tests, but can create baffling symptoms if
1266 side effects from one test to the next affect outcomes. ``DocTestFinder``
1267 has been changed to sort the list of tests it returns.
1268
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001269- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001270 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001271
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001272- Bug #978833: Really close underlying socket in _socketobject.close.
1273
Georg Brandldb232dc2006-08-20 13:15:43 +00001274- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1275 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001276
Georg Brandlcf0c1722006-07-26 07:23:32 +00001277- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1278 to recursive calls and call it with the failing package name.
1279
Martin v. Löwis0b483032006-07-25 09:53:12 +00001280- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1281
Georg Brandlc13c34c2006-07-24 14:09:56 +00001282- Patch #1515343: Fix printing of deprecated string exceptions with a
1283 value in the traceback module.
1284
Greg Ward48fae7a2006-07-23 16:05:51 +00001285- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1286
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001287- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1288
Brett Cannoncaebe222006-07-18 04:41:36 +00001289- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1290 argument tuple. For arguments where zero is illegal, the value is forced to
1291 the minimum value that is correct. This is to support an undocumented but
1292 common way people used to fill in inconsequential information in the time
1293 tuple pre-2.4.
1294
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001295- Patch #1220874: Update the binhex module for Mach-O.
1296
Barry Warsawb110bad2006-07-21 14:51:07 +00001297- The email package has improved RFC 2231 support, specifically for
1298 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1299 (name*0=<blah>) parameter continuations. This may change the types of
1300 values returned from email.message.Message.get_param() and friends.
1301 Specifically in some cases where non-encoded continuations were used,
1302 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1303 will just return the string (since non-encoded continuations don't have
1304 charset and language parts).
1305
1306 Also, whereas % values were decoded in all parameter continuations, they are
1307 now only decoded in encoded parameter parts.
1308
Ronald Oussoren3075e162006-07-25 20:28:55 +00001309- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1310
1311- Bug #1517996: IDLE now longer shows the default Tk menu when a
1312 path browser, class browser or debugger is the frontmost window on MacOS X
1313
Barry Warsaw00decd72006-07-27 23:43:15 +00001314- Patch #1520294: Support for getset and member descriptors in types.py,
1315 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1316 of an object against these built-in types and more importantly, for getting
1317 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001320Extension Modules
1321-----------------
1322
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001323- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1324 a socket operation on a socket with a timeout, the exception will be
1325 caught correctly. Previously, the exception was not caught.
1326
Thomas Heller1393d6a2006-07-28 21:43:20 +00001327- Patch #1529514: The _ctypes extension is now compiled on more
1328 openbsd target platforms.
1329
Tim Peters9cab5932006-07-28 00:30:00 +00001330- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1331 a memory leak, affecting pickles and deep copies.
1332
Tim Petersbc24eee2006-07-27 01:14:53 +00001333- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001334 Paul Eggert.
1335
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001336- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1337
Thomas Hellerce049a02006-07-14 17:51:14 +00001338- Patch #1521817: Index range checking on ctypes arrays containing
1339 exactly one element enabled again. This allows iterating over these
1340 arrays, without the need to check the array size before.
1341
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001342- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001343 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001344 /dev/null in certain cases; this is now fixed.
1345
Thomas Heller47d7a062006-07-12 08:43:47 +00001346- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1347 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001348
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001349- Because of a misspelled preprocessor symbol, ctypes was always
1350 compiled without thread support; this is now fixed.
1351
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001352- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1353 methods now allow their database parameter to be None as the
1354 sleepycat API allows.
1355
Matt Flemingec926502006-07-28 11:27:27 +00001356- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1357 bluetooth API compared with Linux and FreeBSD.
1358
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001359Tests
1360-----
1361
1362- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1363 how long the test file should take to play. Now accepts taking 2.93 secs
1364 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1365
Georg Brandl4793aa32006-07-28 18:31:39 +00001366- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1367 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1368 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001375Mac
1376---
1377
1378- PythonLauncher now works correctly when the path to the script contains
1379 characters that are treated specially by the shell (such as quotes).
1380
1381- Bug #1527397: PythonLauncher now launches scripts with the working directory
1382 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001383 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001384 expect.

1393-----------------
1394
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001395- Bug #1441486: The literal representation of -(sys.maxint - 1)
1396 again evaluates to a int object, not a long.
1397
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001398- Bug #1501934: The scope of global variables that are locally assigned
1399 using augmented assignment is now correctly determined.
1400
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001401- Bug #927248: Recursive method-wrapper objects can now safely
1402 be released.
1403
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001404- Bug #1417699: Reject locale-specific decimal point in float()
1405 and atof().
1406
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001407- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1408 omit a default "error" argument for NULL pointer. This allows
1409 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001410
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001411- Bug #1519018: 'as' is now validated properly in import statements.
1412
Neal Norwitz28746ab2006-07-09 22:14:42 +00001413- On 64 bit systems, int literals that use less than 64 bits are
1414 now ints rather than longs.
1415
Neal Norwitzed657552006-07-10 00:04:44 +00001416- Bug #1512814, Fix incorrect lineno's when code at module scope
1417 started after line 256.
1418
Tim Peters32a83612006-07-10 21:08:24 +00001419- New function ``sys._current_frames()`` returns a dict mapping thread
1420 id to topmost thread stack frame. This is for expert use, and is
1421 especially useful for debugging application deadlocks. The functionality
1422 was previously available in Fazal Majid's ``threadframe`` extension
1423 module, but it wasn't possible to do this in a wholly threadsafe way from
1424 an extension.

1428
Martin v. Löwis77621582006-07-30 13:27:31 +00001429- Bug #1257728: Mention Cygwin in distutils error message about a missing
1430 VS 2003.
1431
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001432- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1433
Tim Peters32a83612006-07-10 21:08:24 +00001434- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001435 environment variable to be set in order to the SDK environment
1436 for finding the compiler, include files, etc.

1439
Nick Coghlan2d792252006-07-06 13:47:18 +00001440- warnings.py now ignores ImportWarning by default
1441
Thomas Woutersadd19112006-07-05 11:03:49 +00001442- string.Template() now correctly handles tuple-values. Previously,
1443 multi-value tuples would raise an exception and single-value tuples would
1444 be treated as the value they contain, instead.
1445
Martin v. Löwisede77f52006-07-03 13:01:35 +00001446- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1447 even if some data are received.
1448
Martin v. Löwis45482392006-07-03 12:28:58 +00001449- Bug #1267547: Put proper recursive setup.py call into the
1450 spec file generated by bdist_rpm.
1451
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001452- Bug #1514693: Update turtle's heading when switching between
1453 degrees and radians.
1454
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001455- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001456 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001457
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001458- Bug #1514703: Only setup canvas window in turtle when the canvas
1459 is created.
1460
Martin v. Löwis7596e832006-07-01 15:33:37 +00001461- Bug #1513223: .close() of a _socketobj now releases the underlying
1462 socket again, which then gets closed as it becomes unreferenced.
1463
Fred Drake10497c82006-06-29 02:57:48 +00001464- Bug #1504333: Make sgmllib support angle brackets in quoted
1465 attribute values.
1466
1467- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1468 sgmllib ('[' and ']' were not accepted).
1469
Georg Brandl1be63af2006-06-28 20:23:25 +00001470- Fix a bug in the turtle module's end_fill function.
1471
Brett Cannon53ab5b72006-06-22 16:49:14 +00001472- Bug #1510580: The 'warnings' module improperly required that a Warning
1473 category be either a types.ClassType and a subclass of Warning. The proper
1474 check is just that it is a subclass with Warning as the documentation states.
1475
Georg Brandlad29e632006-06-21 17:45:17 +00001476- The compiler module now correctly compiles the new try-except-finally
1477 statement (bug #1509132).
1478
Neal Norwitz60373cd2006-06-22 06:30:50 +00001479- The wsgiref package is now installed properly on Unix.
1480
Vinay Sajip28e57612006-07-01 10:45:20 +00001481- A bug was fixed in logging.config.fileConfig() which caused a crash on
1482 shutdown when fileConfig() was called multiple times.
1483
Gerhard Häring762fbd32006-07-02 17:48:30 +00001484- The sqlite3 module did cut off data from the SQLite database at the first
1485 null character before sending it to a custom converter. This has been fixed
1486 now.
1487

1489-----------------
1490
Tim Peters112aad32006-07-19 00:03:19 +00001491- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1492 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1493 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001494
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001495- Assigning None to pointer type fields in ctypes structures possible
1496 overwrote the wrong fields, this is fixed now.
1497
1498- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1499 on non-Windows platforms.
1500
1501- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1502 integer or long, without range checking.
1503
1504- Patch #1517790: It is now possible to use custom objects in the ctypes
1505 foreign function argtypes sequence as long as they provide a from_param
1506 method, no longer is it required that the object is a ctypes type.
1507
1508- The '_ctypes' extension module now works when Python is configured
1509 with the --without-threads option.
1510
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001511- Bug #1513646: os.access on Windows now correctly determines write
1512 access, again.
1513
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001514- Bug #1512695: cPickle.loads could crash if it was interrupted with
1515 a KeyboardInterrupt.
1516
Neal Norwitza12aa882006-07-06 06:45:08 +00001517- Bug #1296433: parsing XML with a non-default encoding and
1518 a CharacterDataHandler could crash the interpreter in pyexpat.
1519
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001520- Patch #1516912: improve Modules support for OpenVMS.

1526
Tim Peters32a83612006-07-10 21:08:24 +00001527- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001528 Previously, the slight difference could cause compilation errors of the
1529 'zlib' module on systems with more than one version of zlib.
1530
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001531- The MSI compileall step was fixed to also support a TARGETDIR

1562Core and builtins
1563-----------------
1564
Georg Brandla56b9152006-06-19 06:35:54 +00001565- Patch #1507676: Error messages returned by invalid abstract object operations
1566 (such as iterating over an integer) have been improved and now include the
1567 type of the offending object to help with debugging.
1568
Brett Cannonea3912b2006-06-13 21:46:41 +00001569- Bug #992017: A classic class that defined a __coerce__() method that returned
1570 its arguments swapped would infinitely recurse and segfault the interpreter.
1571
Neal Norwitz909eb122006-06-12 02:13:21 +00001572- Fix the socket tests so they can be run concurrently.
1573
Neal Norwitzb9845e72006-06-12 02:11:18 +00001574- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001575 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001576
Brett Cannon22565aa2006-06-09 22:31:23 +00001577- Bug #532646: object.__call__() will continue looking for the __call__
1578 attribute on objects until one without one is found. This leads to recursion
1579 when you take a class and set its __call__ attribute to an instance of the
1580 class. Originally fixed for classic classes, but this fix is for new-style.
1581 Removes the infinite_rec_3 crasher.
1582
Georg Brandl24250812006-06-09 18:45:48 +00001583- The string and unicode methods startswith() and endswith() now accept
1584 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1585
Brett Cannonde3b0522006-06-08 17:00:45 +00001586- Buffer objects, at the C level, never used the char buffer
1587 implementation even when the char buffer for the wrapped object was
1588 explicitly requested (originally returned the read or write buffer).
1589 Now a TypeError is raised if the char buffer is not present but is
1590 requested.
1591
Georg Brandlddbaa662006-06-04 21:56:52 +00001592- Patch #1346214: Statements like "if 0: suite" are now again optimized
1593 away like they were in Python 2.4.
1594
Georg Brandlb7c8f542006-05-27 12:30:25 +00001595- Builtin exceptions are now full-blown new-style classes instead of
1596 instances pretending to be classes, which speeds up exception handling
1597 by about 80% in comparison to 2.5a2.
1598
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001599- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1600 Unicode 4.1.
1601
Georg Brandlf4ef1162006-05-26 18:03:31 +00001602- Patch #921466: sys.path_importer_cache is now used to cache valid and
1603 invalid file paths for the built-in import machinery which leads to
1604 fewer open calls on startup.
1605
Tim Peters696cf432006-05-24 21:10:40 +00001606- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1607 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1608 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1609 the number of input digits (it was and remains linear-time for bases
1610 2, 4, 8, 16 and 32).
1611
Tim Petersb713ec22006-05-23 18:45:30 +00001612- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1613 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1614 an integer close to ``sys.maxint``. This was repaired by patch
1615 #1335972, which also gives a nice speedup.
1616
Richard Jonescebbefc2006-05-23 18:28:17 +00001617- Patch #1337051: reduced size of frame objects.
1618
1619- PyErr_NewException now accepts a tuple of base classes as its
1620 "base" parameter.
1621
Richard Jones7c88dcc2006-05-23 10:37:38 +00001622- Patch #876206: function call speedup by retaining allocated frame
1623 objects.
1624
Georg Brandl7b90e162006-05-18 07:01:27 +00001625- Bug #1462152: file() now checks more thoroughly for invalid mode
1626 strings and removes a possible "U" before passing the mode to the
1627 C library function.
1628
Neal Norwitz1004a532006-05-15 07:17:23 +00001629- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1630
Neal Norwitz373f0a72006-05-15 07:04:36 +00001631- Bug #1487966: Fix SystemError with conditional expression in assignment
1632
Martin v. Löwis879768d2006-05-11 13:28:43 +00001633- WindowsError now has two error code attributes: errno, which carries
1634 the error values from errno.h, and winerror, which carries the error
1635 values from winerror.h. Previous versions put the winerror.h values
1636 (from GetLastError()) into the errno attribute.
1637
Martin v. Löwis77736712006-05-04 05:51:03 +00001638- Patch #1475845: Raise IndentationError for unexpected indent.
1639
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001640- Patch #1479181: split open() and file() from being aliases for each other.
1641
Tim Peters44bd9862006-06-01 13:49:23 +00001642- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1643 methods were always silently ignored by dictionaries when comparing keys.
1644 They are now passed through (except when using the C API function
1645 ``PyDict_GetItem()``, whose semantics did not change).
1646
1647- Bug #1456209: In some obscure cases it was possible for a class with a
1648 custom ``__eq__()`` method to confuse dict internals when class instances
1649 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1650 No, you don't have any code that did this ;-)

1658
Brett Cannon6ee7d012006-06-08 16:23:04 +00001659- Change binascii.hexlify to accept a read-only buffer instead of only a char
1660 buffer and actually follow its documentation.
1661
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001662- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1663
Nick Coghlanc649ec52006-05-29 12:43:05 +00001664- Patch #1478788 (modified version): The functional extension module has
1665 been renamed to _functools and a functools Python wrapper module added.
1666 This provides a home for additional function related utilities that are
1667 not specifically about functional programming. See PEP 309.
1668
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001669- Patch #1493701: performance enhancements for struct module.

1674 copy() method.
1675
Andrew MacIntyre92913322006-06-13 15:04:24 +00001676- Patch #1454481: thread stack size is now tunable at runtime for thread
1677 enabled builds on Windows and systems with Posix threads support.
1678
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001679- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1680 (up to the system limit of 32K characters).
1681
1682- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1683 As a result, these functions now raise WindowsError instead of OSError.
1684
Tim Peters7a822da2006-05-25 21:50:17 +00001685- ``time.clock()`` on Win64 should use the high-performance Windows
1686 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1687 Windows platforms).
1688
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001689- Calling Tk_Init twice is refused if the first call failed as that
1690 may deadlock.
1691
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001692- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1693 accept it without potentially using an uninitialized pointer.
1694
1695- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1696 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1703 parameter is supplied. [SF pybsddb bug #1477863]
1704
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001705- bsddb: the __len__ method of a DB object has been fixed to return correct
1706 results. It could previously incorrectly return 0 in some cases.
1707 Fixes SF bug 1493322 (pybsddb bug 1184012).
1708
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001709- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1710 aborts the db transaction safely when a modifier callback fails.
1711 Fixes SF python patch/bug #1408584.
1712
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001713- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001714 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001715 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1716 database calls that would previously deadlock. [SF python bug #775414]

1746 double-byte encodings.
1747
Tim Peters43898b42006-06-14 04:09:25 +00001748- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1749 guarantee that adjacent triples in the return list always describe
1750 non-adjacent blocks. Previously, a pair of matching blocks could end
1751 up being described by multiple adjacent triples that formed a partition
1752 of the matching pair.
1753
Greg Ward0e0c9f42006-06-11 16:24:11 +00001754- Bug #1498146: fix optparse to handle Unicode strings in option help,

Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001762- The wsgiref package has been added to the standard library.
1763
Nick Coghlan676725d2006-06-08 13:54:49 +00001764- The functions update_wrapper() and wraps() have been added to the functools
1765 module. These make it easier to copy relevant metadata from the original
1766 function when writing wrapper functions.
1767
Tim Petersd6a9eef2006-06-05 01:48:21 +00001768- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1769 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001770
Martin v. Löwis3f767792006-06-04 19:36:28 +00001771- Patch #1359618: Speed up charmap encoder by using a trie structure
1772 for lookup.
1773
Tim Petersd609b1a2006-06-02 23:22:51 +00001774- The functions in the ``pprint`` module now sort dictionaries by key
1775 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1776 if and only if its display required more than one line, although that
1777 wasn't documented. The new behavior increases predictability; e.g.,
1778 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1779
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001780- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1781 (thanks for J. J. Lee).
1782
Georg Brandl2b330372006-05-28 20:23:12 +00001783- Patch #1496206: improve urllib2 handling of passwords with respect to
1784 default HTTP and HTTPS ports.
1785
George Yoshidaf3c65de2006-05-28 16:39:09 +00001786- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1787
Bob Ippolito7298f272006-05-23 18:43:47 +00001788- Patch #1281707: speed up gzip.readline.
1789
Georg Brandlb89316f2006-05-17 15:51:16 +00001790- Patch #1180296: Two new functions were added to the locale module:
1791 format_string() to get the effect of "format % items" but locale-aware,
1792 and currency() to format a monetary number with currency sign.
1793
Georg Brandle3a25832006-05-17 14:56:04 +00001794- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1795 and several features added, such as speed and geometry control.
1796
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001797- Patch #1488881: add support for external file objects in bz2 compressed
1798 tarfiles.
1799
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001800- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1801 stdout arguments, making it possible to redirect input and output
1802 for remote debugging.
1803
1804- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1805 a couple of issues, notably handling of long file names using the
1806 GNU LONGNAME extension.
1807
1808- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1809 new flag when ``name`` is already the name of an option flag.
1810
1811- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1812 package.
1813
1814- Patch #1472854: make the rlcompleter.Completer class usable on non-
1815 UNIX platforms.
1816
1817- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1818
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001819- Bug #1472827: correctly escape newlines and tabs in attribute values in
1820 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001850What's New in Python 2.5 alpha 2?
1851=================================
1852
1853*Release date: 27-APR-2006*
1854
1855Core and builtins
1856-----------------
1857
Thomas Heller1b046642006-04-18 18:51:06 +00001858- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1859 by converting these apis from macros into exported functions again:
1860
1861 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1862 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1863 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1864 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1865 PyRun_String Py_CompileString
1866
Martin v. Löwis45294a92006-04-18 06:24:08 +00001867- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1868
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001869- All uses of PyStructSequence_InitType have been changed to initialize
1870 the type objects only once, even if the interpreter is initialized
1871 multiple times.
1872
Neal Norwitz61546162006-04-14 05:20:28 +00001873- Bug #1454485, array.array('u') could crash the interpreter. This was
1874 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1875 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1876
1877- Py_UNICODE is unsigned. It was always documented as unsigned, but
1878 due to a bug had a signed value in previous versions.
1879
Tim Peters3a5e8b12006-04-11 01:44:07 +00001880- Patch #837242: ``id()`` of any Python object always gives a positive
1881 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1882 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001883 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001884 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001885
Tim Peters3a5e8b12006-04-11 01:44:07 +00001886 def __hash__(self):
1887 return id(self) # WRONG
1888
1889 because a hash result must be a (short) Python int but it was always
1890 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001891 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001892 was always usable as a hash value before this patch. That's no longer
1893 necessarily so.
1894
1895- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001896 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001897 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001898 #1454844)
1899
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001900- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1901 involving generators that have paused outside of any ``try`` or ``with``
1902 blocks. (In 2.5a1, a paused generator that was part of a reference
1903 cycle could not be garbage collected, regardless of whether it was
1904 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001905
Anthony Baxter51bcb682006-04-05 14:51:42 +00001906Extension Modules

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001909- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1910 is a macro.
1911
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001912- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1913 fails with an error condition.
1914
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001915- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1916
1917- Bug #1117761: bsddb.*open() no longer raises an exception when using
1918 the cachesize parameter.
1919
1920- Bug #1149413: bsddb.*open() no longer raises an exception when using
1921 a temporary db (file=None) with the 'n' flag to truncate on open.
1922
1923- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1924 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001925
Armin Rigoa9017c32006-04-19 11:50:27 +00001926- Patch #1062014: AF_UNIX sockets under Linux have a special
1927 abstract namespace that is now fully supported.

1931
Peter Astrand7d1d4362006-07-14 14:04:45 +00001932- Bug #1223937: subprocess.CalledProcessError reports the exit status
1933 of the process using the returncode attribute, instead of
1934 abusing errno.
1935
Tim Peters711bf302006-04-25 03:31:36 +00001936- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1937 a doctest to be skipped (the code is not run, and the expected output
1938 or exception is ignored).
1939
Nick Coghlanda2268f2006-04-24 04:37:15 +00001940- Fixed contextlib.nested to cope with exceptions being raised and
1941 caught inside exit handlers.
1942
Greg Wardab05edc2006-04-23 03:47:58 +00001943- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1944 hex, octal, or binary; add ``append_const`` action; keep going if
1945 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1946 added ``epilog`` for better help generation).
1947
Tim Peters21fbd572006-04-21 21:18:10 +00001948- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1949 called from a thread spawned as a side effect of importing a module.
1950
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001951- The pydoc module now supports documenting packages contained in
1952 .zip or .egg files.
1953
1954- The pkgutil module now has several new utility functions, such
1955 as ``walk_packages()`` to support working with packages that are either
1956 in the filesystem or zip files.
1957
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001958- The mailbox module can now modify and delete messages from
1959 mailboxes, in addition to simply reading them. Thanks to Gregory
1960 K. Johnson for writing the code, and to the 2005 Google Summer of
1961 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001962
Tim Petersc7605f22006-04-17 21:12:33 +00001963- The ``__del__`` method of class ``local`` in module ``_threading_local``
1964 returned before accomplishing any of its intended cleanup.
1965
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001966- Patch #790710: Add breakpoint command lists in pdb.
1967

1971
Anthony Baxtere29002c2006-04-12 12:07:31 +00001972- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1973 Windows. Bug #1469163.
1974
Phillip J. Eby47032112006-04-11 01:07:43 +00001975- The warnings, linecache, inspect, traceback, site, and doctest modules
1976 were updated to work correctly with modules imported from zipfiles or
1977 via other PEP 302 __loader__ objects.
1978
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001979- Patch #1467770: Reduce usage of subprocess._active to processes which
1980 the application hasn't waited on.

1991
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001992- The Makefile now has a reindent target, which runs reindent.py on
1993 the library.
1994
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001995- Patch #1470875: Building Python with MS Free Compiler

2000 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002001 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002002 CXX from --with-cxx-main, see description in README.
2003

2007
Tim Peters8931ff12006-05-13 23:28:20 +00002008- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2009 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2010 and "%zu" for unsigned integers of type ``size_t``.
2011
Anthony Baxter51bcb682006-04-05 14:51:42 +00002012Tests
2013-----
2014
Nick Coghlanda2268f2006-04-24 04:37:15 +00002015- test_contextlib now checks contextlib.nested can cope with exceptions
2016 being raised and caught inside exit handlers.

Nick Coghlan27ec1a72006-04-24 04:32:47 +00002018- test_cmd_line now checks operation of the -m and -c command switches
2019
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002020- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2021 it separately and by hand. It also wasn't cleaning up its changes to
2022 the current Decimal context.
2023
Thomas Woutersabd08882006-04-26 15:53:30 +00002024- regrtest.py now has a -M option to run tests that test the new limits of
2025 containers, on 64-bit architectures. Running these tests is only sensible
2026 on 64-bit machines with more than two gigabytes of memory. The argument
2027 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002048What's New in Python 2.5 alpha 1?
2049=================================
2050
Anthony Baxterebed3f62006-04-03 15:03:44 +00002051*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002052
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002053Core and builtins
2054-----------------
2055
Nick Coghlan43832302006-04-23 17:04:07 +00002056- PEP 338: -m command line switch now delegates to runpy.run_module

2058
Martin v. Löwisc661b882006-04-20 04:54:23 +00002059- On Windows, .DLL is not an accepted file name extension for
2060 extension modules anymore; extensions are only found if they
2061 end in .PYD.
2062
Martin v. Löwisea62d252006-04-03 10:56:49 +00002063- Bug #1421664: sys.stderr.encoding is now set to the same value as
2064 sys.stdout.encoding.

Anthony Baxter262c00a2006-03-30 10:53:17 +00002070- Fixed bug #1459029 - unicode reprs were double-escaped.
2071
Hye-Shik Changd478f342006-03-23 12:32:36 +00002072- Patch #1396919: The system scope threads are reenabled on FreeBSD
2073 5.4 and later versions.
2074
Neal Norwitze98ccf62006-03-23 05:39:47 +00002075- Bug #1115379: Compiling a Unicode string with an encoding declaration
2076 now gives a SyntaxError.
2077
Georg Brandlabd1ff82006-03-18 07:59:59 +00002078- Previously, Python code had no easy way to access the contents of a
2079 cell object. Now, a ``cell_contents`` attribute has been added
2080 (closes patch #1170323).
2081
Tim Peterscf79aac2006-03-16 01:14:46 +00002082- Patch #1123430: Python's small-object allocator now returns an arena to
2083 the system ``free()`` when all memory within an arena becomes unused
2084 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2085 freed. Some applications will see a drop in virtual memory size now,
2086 especially long-running applications that, from time to time, temporarily
2087 use a large number of small objects. Note that when Python returns an
2088 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002089 platform C library will in turn return that memory to the operating system.
2090 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002091 appears to be effective at least on Microsoft C and gcc-based systems.
2092 Thanks to Evan Jones for hard work and patience.
2093
Georg Brandl533ff6f2006-03-08 18:09:27 +00002094- Patch #1434038: property() now uses the getter's docstring if there is
2095 no "doc" argument given. This makes it possible to legitimately use
2096 property() as a decorator to produce a read-only property.
2097
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002098- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2099 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2100 of requiring an int or long in slicing and a few other contexts, enabling
2101 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2102
Neal Norwitz995acdf2006-03-07 05:01:00 +00002103- Fixed various bugs reported by Coverity's Prevent tool.
2104
Brett Cannonbf364092006-03-01 04:25:17 +00002105- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2106 new exception base class, BaseException, which has a new message attribute.
2107 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2108 Raising a string exception now raises a DeprecationWarning.
2109
Thomas Woutersfb609f42006-02-28 16:37:25 +00002110- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2111 explicitly relative, using 'from .module import name' to mean 'from the same
2112 package as this module is in. Imports without dots still default to the
2113 old relative-then-absolute, unless 'from __future__ import
2114 absolute_import' is used.
2115
Brett Cannona7446e32006-02-27 23:39:10 +00002116- Properly check if 'warnings' raises an exception (usually when a filter set
2117 to "error" is triggered) when raising a warning for raising string
2118 exceptions.
2119
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002120- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002121 The name was removed from Include/code.h.
2122
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002123- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002124
Guido van Rossum1968ad32006-02-25 22:38:04 +00002125- Patch 1433928:
2126 - The copy module now "copies" function objects (as atomic objects).
2127 - dict.__getitem__ now looks for a __missing__ hook before raising
2128 KeyError.
2129
Tim Peters84ef21c2006-02-28 20:39:06 +00002130- PEP 343: with statement implemented. Needs ``from __future__ import
2131 with_statement``. Use of 'with' as a variable will generate a warning.
2132 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002133 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002134 The following objects have __context__ methods:
2135 - The built-in file type.
2136 - The thread.LockType type.
2137 - The following types defined by the threading module:
2138 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2139 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002140
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002141- Fix the encodings package codec search function to only search
2142 inside its own package. Fixes problem reported in patch #1433198.
2143
2144 Note: Codec packages should implement and register their own
2145 codec search function. PEP 100 has the details.
2146
Tim Peters9ea89d22006-06-04 03:26:02 +00002147- PEP 353: Using ``Py_ssize_t`` as the index type.
2148
2149- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2150 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2151 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2152 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2153 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002154
Neal Norwitzfc76d632006-01-10 06:03:13 +00002155- Patch #1400181, fix unicode string formatting to not use the locale.
2156 This is how string objects work. u'%f' could use , instead of .
2157 for the decimal point. Now both strings and unicode always use periods.
2158
Neal Norwitz671b9e32006-01-09 07:07:12 +00002159- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2160 configure would break checking curses.h.
2161
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002162- Bug #959576: The pwd module is now builtin. This allows Python to be
2163 built on UNIX platforms without $HOME set.
2164
Neal Norwitzc10978f2005-12-19 06:07:16 +00002165- Bug #1072182, fix some potential problems if characters are signed.
2166
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002167- Bug #889500, fix line number on SyntaxWarning for global declarations.
2168
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002169- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2170
Neal Norwitze7214a12005-12-18 05:03:17 +00002171- Support for converting hex strings to floats no longer works.
2172 This was not portable. float('0x3') now raises a ValueError.
2173
Barry Warsaw2a38a862005-12-18 01:27:35 +00002174- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002175 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002176 is now displayed in interactive prompt banner.
2177
Georg Brandlfa166682005-12-17 21:45:17 +00002178- Implementation of PEP 341 - Unification of try/except and try/finally.
2179 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002180 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002181
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002182- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2183 now encodes backslash correctly.
2184
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002185- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2186
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002187- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002188 and long longs.
2189
Neal Norwitz67715f02005-11-09 06:59:35 +00002190- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002191 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002192 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002193
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002194- Replaced most Unicode charmap codecs with new ones using the
2195 new Unicode translate string feature in the builtin charmap
2196 codec; the codecs were created from the mapping tables available
2197 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2198 encodings now include a mapping for the Apple logo)
2199
Tim Peterse3547fd2005-12-16 23:13:57 +00002200- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002201
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002202- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002203
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002204- A new AST parser implementation was completed. The abstract
2205 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002206 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002207
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002208- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002209 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2210
Neal Norwitz708e51a2005-10-03 04:48:15 +00002211- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2212
Neal Norwitz11bd1192005-10-03 00:54:56 +00002213- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2214 Provide a warning when a directory is passed on the command line.
2215
Neal Norwitz40d37812005-10-02 01:48:49 +00002216- Fix segfault with invalid coding.
2217
2218- SF bug #772896: unknown encoding results in MemoryError.
2219
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002220- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002221 supported a __len__() method which evaluated to False when the iterator
2222 was empty.
2223
Guido van Rossum630db602005-09-20 18:49:54 +00002224- On 64-bit platforms, when __len__() returns a value that cannot be
2225 represented as a C int, raise OverflowError.
2226
Skip Montanarof8948ca2005-09-19 03:54:46 +00002227- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002228 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002229
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002230- SF bug #893549: parsing keyword arguments was broken with a few format
2231 codes.
2232
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002233- Changes donated by Elemental Security to make it work on AIX 5.3
2234 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2235 bug #105470: test_pwd fails on 64bit system (Opteron).
2236
Guido van Rossum539c6622005-09-14 17:49:54 +00002237- Changes donated by Elemental Security to make it work on HP-UX 11 on
2238 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2239
Georg Brandl4550b8d2005-08-26 06:43:52 +00002240- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002241 (fixes bug #1119418).
2242
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002243- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2244
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002245- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2246 exceptions that cause a function to exit.
2247
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002248- The implementation of set() and frozenset() was revised to use its
2249 own internal data structure. Memory consumption is reduced by 1/3
2250 and there are modest speed-ups as well. The API is unchanged.
2251
Tim Petersde7990b2005-07-17 23:45:23 +00002252- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2253
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002254- SF bug #1229429: PyObject_CallMethod failed to decrement some
2255 reference counts in some error exit cases.
2256
Tim Petersecc6e6a2005-07-10 22:30:55 +00002257- SF bug #1185883: Python's small-object memory allocator took over
2258 a block managed by the platform C library whenever a realloc specified
2259 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002260 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002261 portable way to copy data from the C-managed block into Python's
2262 small-object space without risking a memory fault. Python's small-object
2263 realloc now leaves such blocks under the control of the platform C
2264 realloc.
2265
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002266- SF bug #1232517: An overflow error was not detected properly when
2267 attempting to convert a large float to an int in os.utime().
2268
Raymond Hettinger3296e692005-06-29 23:29:56 +00002269- SF bug #1224347: hex longs now print with lowercase letters just
2270 like their int counterparts.
2271
Michael W. Hudson188d4362005-06-20 16:52:57 +00002272- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2273 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2274 interpreter states; back out that fix and do a better job (see
2275 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2276 for a longer write-up of the problem).
2277
Michael W. Hudsondf888462005-06-03 14:41:55 +00002278- SF patch #1180995: marshal now uses a binary format by default when
2279 serializing floats.
2280
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002281- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2282 the routines that promise to produce IEEE 754 binary representations
2283 of floats now simply copy bytes around.
2284
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002285- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2286 278.
2287
Brett Cannonc3647ac2005-04-26 03:45:26 +00002288- patch #1109424: int, long, float, complex, and unicode now check for the
2289 proper magic slot for type conversions when subclassed. Previously the
2290 magic slot was ignored during conversion. Semantics now match the way
2291 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002292 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002293 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002294 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002295
Barry Warsawc8d907c2005-04-19 23:43:40 +00002296- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2297 NULL, now raise an AttributeError when attempting to set or delete the
2298 attribute. Previously a TypeError was raised, but this was inconsistent
2299 with the equivalent pure-Python implementation.
2300
Michael W. Hudson774479c2005-04-18 08:46:17 +00002301- It is now safe to call PyGILState_Release() before
2302 PyEval_InitThreads() (note that if there is reason to believe there
2303 are multiple threads around you still must call PyEval_InitThreads()
2304 before using the Python API; this fix is for extension modules that
2305 have no way of knowing if Python is multi-threaded yet).
2306
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002307- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2308 disabled caused a crash.
2309
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002310- Bug #1165306: instancemethod_new allowed the creation of a method
2311 with im_class == im_self == NULL, which caused a crash when called.
2312
Tim Petersecc6e6a2005-07-10 22:30:55 +00002313- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002314 fixes the crash seen in bug #1165761
2315
Raymond Hettinger96229b12005-03-11 06:49:40 +00002316- Added two new builtins, any() and all().
2317
Brett Cannon409d8f22005-03-05 06:47:57 +00002318- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002319 (e.g., ``class C(): pass`` is no longer a syntax error).
2320 Patch #1176012 added support to the 'parser' module and 'compiler' package
2321 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002322
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002323- Patch #1115086: Support PY_LONGLONG in structmember.
2324
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002325- Bug #1155938: new style classes did not check that __init__() was
2326 returning None.
2327
Tim Petersecc6e6a2005-07-10 22:30:55 +00002328- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002329 ('\') with a specific error message.
2330
Martin v. Löwisff232d72005-03-03 09:24:38 +00002331- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2332
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002333- Bug #1124295: the __name__ attribute of file objects was
2334 inadvertently made inaccessible in restricted mode.

2355 unicode instance if the argument is not an instance of basestring and
2356 calling __str__ on the argument returns a unicode instance.
2357
Tim Petersf4e69282006-02-27 17:15:31 +00002358- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2359 current thread state when the auto-GIL-state machinery knows about
2360 it (since the thread state is being deleted, continuing to remember it
2361 can't help, but can hurt if another thread happens to get created with
2362 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00002558- PEP 338: new module runpy defines a run_module function to support
2559 executing modules which provide access to source code or a code object
2560 via the PEP 302 import mechanisms.

2570 in attribute values.
2571
Anthony Baxterc51ee692006-04-01 00:57:31 +00002572- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002573 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002574 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002575 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002577- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2578 aren't officially supported here, and trying to use them will probably

Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002601- email 4.0 package now integrated. This is largely the same as the email 3.0
2602 package that was included in Python 2.3, except that PEP 8 module names are
2603 now used (e.g. mail.message instead of email.Message). The MIME classes
2604 have been moved to a subpackage (e.g. email.mime.text instead of
2605 email.MIMEText). The old names are still supported for now. Several
2606 deprecated Message methods have been removed and lots of bugs have been
2607 fixed. More details can be found in the email package documentation.
2608
Walter Dörwald40108c92006-03-27 08:15:44 +00002609- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2610 (a subclass of tuple) that provides incremental decoders and encoders
2611 (a way to use stateful codecs without the stream API). Python functions
2612 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2613 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2614 have been added.

2695 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2696 Ronald L. Rivest offered this advice for Python:
2697
2698 "The consensus of researchers in this area (at least as
2699 expressed at the NIST Hash Function Workshop 10/31/05),
2700 is that SHA-256 is a good choice for the time being, but
2701 that research should continue, and other alternatives may
2702 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002703

Guido van Rossumd0641422005-02-03 15:01:24 +00002863- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2864 disables recursive traversal through instance attributes, which can
2865 be exploited in various ways.
2866
Tim Peterse3547fd2005-12-16 23:13:57 +00002867- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002868 flags on the HTTP listening socket.
2869
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002870- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2871 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2872
Fred Drakefbdeaad2006-07-29 16:56:15 +00002873- Patches #893642, #1039083: add allow_none, encoding arguments to
2874 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002875
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002876- Bug #1110478: Revert os.environ.update to do putenv again.
2877
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002878- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2879
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002880- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2881
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002882- Enhancements to the csv module:
2883
2884 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002885 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002886 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002887 + Dialect parameter parsing has been re-implemented to improve error
2888 reporting.
2889 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2890 dictates.
2891 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002892 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002893 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002894 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2895 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002896 + reader now allows \r characters to be quoted (previously it only allowed
2897 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002898 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002899 + Dialect classes passed to the module are no longer instantiated by
2900 the module before being parsed (the former validation scheme required
2901 this, but the mechanism was unreliable).
2902 + The dialect registry now contains instances of the internal
2903 C-coded dialect type, rather than references to python objects.
2904 + the internal c-coded dialect type is now immutable.
2905 + register_dialect now accepts the same keyword dialect specifications
2906 as the reader and writer, allowing the user to register dialects
2907 without first creating a dialect class.
2908 + a configurable limit to the size of parsed fields has been added -
2909 previously, an unmatched quote character could result in the entire
2910 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002911 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002912 the parser field size limit (returning the former limit). The initial
2913 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002914 + A line_num attribute has been added to the reader object, which tracks
2915 the number of lines read from the source iterator. This is not
2916 the same as the number of records returned, as records can span
2917 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002918 + reader and writer objects were not being registered with the cyclic-GC.
2919 This has been fixed.
2920
Brett Cannone6539c42005-01-08 02:43:53 +00002921- _DummyThread objects in the threading module now delete self.__block that is
2922 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2923 lock primitives tend to be limited in number and thus should not be wasted on
2924 a _DummyThread object. Fixes bug #1089632.
2925
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002926- The imghdr module now detects Exif files.
2927
Raymond Hettinger6065d322004-12-20 23:51:53 +00002928- StringIO.truncate() now correctly adjusts the size attribute.
2929 (Bug #951915).
2930
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002931- locale.py now uses an updated locale alias table (built using
2932 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2933 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002934 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002935
Raymond Hettinger3557f422004-12-07 12:02:02 +00002936- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2937
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002938- the pickle module no longer accepts the deprecated None option in the
2939 args tuple returned by __reduce__().
2940
Brett Cannon84667c02004-12-07 03:25:18 +00002941- optparse now optionally imports gettext. This allows its use in setup.py.
2942
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002943- the pickle module no longer uses the deprecated bin parameter.
2944
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002945- the shelve module no longer uses the deprecated binary parameter.
2946
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002947- the pstats module no longer uses the deprecated ignore() method.
2948
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002949- the filecmp module no longer uses the deprecated use_statcache argument.
2950
Raymond Hettinger664347b2004-12-04 21:21:53 +00002951- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2952 extended or overridden by subclasses. Formerly, the subclassed method would
2953 be ignored by the rest of the module. (Bug #1078905).
2954
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002955- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002956 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002957
Walter Dörwald36733692004-12-22 12:50:50 +00002958- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2959 once when a size argument is given. This prevents a buffer overflow in the
2960 tokenizer with very long source lines.
2961
Barry Warsaw538561e2006-01-01 21:48:54 +00002962- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2963 immediately after creating the object, without any intervening
2964 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002965
Skip Montanaro05885812005-01-16 20:48:27 +00002966- The reconvert.quote function can now emit triple-quoted strings. The
2967 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002968
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002969- ``UserString.MutableString`` now supports negative indices in
2970 ``__setitem__`` and ``__delitem__``
2971
Greg Ward40407942005-03-05 02:53:17 +00002972- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2973 correctly.
2974
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002975- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2976 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2977 character even if the user has passed a size parameter to get a proper
2978 line ending. Remove the special handling of a "\r\n" that has been split
2979 between two lines.
2980
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002981- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2982 about illegal code points. The codec now supports PEP 293 style error
2983 handlers.
2984
Walter Dörwald78a78b02005-09-01 12:04:29 +00002985- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002986 from the input stream, so that the output is a byte string in the correct
2987 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002988
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002989- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2990 considering it exactly like a '*'.
2991
Walter Dörwald007f8df2005-10-09 19:42:27 +00002992- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2993 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002994
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002995- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2996
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002997- Patch #1413711: Certain patterns of differences were making difflib
2998 touch the recursion limit.
2999
Walter Dörwald58917a62006-03-31 15:26:22 +00003000- Bug #947906: An object oriented interface has been added to the calendar
3001 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003002 called as a script (e.g. via ``python -mcalendar``). Localized month and
3003 weekday names can be ouput (even if an exotic encoding is used) using
3004 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003005
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003006Build
3007-----
3008
Neal Norwitz602d3392006-03-31 08:21:40 +00003009- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3010 by using -mieee gcc option.
3011

3013
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003014- Build support for Win64-AMD64 was added.
3015
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003016- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3017
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003018- Patch #881820: look for openpty and forkpty also in libbsd.
3019
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003020- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3021 The zlib module is now builtin on Windows.
3022
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003023- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3024
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003025- Bug #1189330: configure did not correctly determine the necessary
3026 value of LINKCC if python was built with GCC 4.0.
3027
Trent Mick8321b422005-07-26 02:29:21 +00003028- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3029 vulnerability in zlib 1.2.1 and 1.2.2.
3030
Brett Cannon08cd5982005-04-24 22:26:38 +00003031- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3032 flags that change binary compatibility. Changes were also made to
3033 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003034 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003035
Bob Ippolitoed233462005-03-29 13:47:59 +00003036- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3037 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3038 no longer exists). This configure patch makes things right.
3039
Martin v. Löwise2713be2005-03-08 15:03:08 +00003040- Bug #1158607: Build with --disable-unicode again.
3041
Brett Cannon46d96232005-02-16 00:07:19 +00003042- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3043 defined. Discovered as a result of not being able to build on OS X.
3044
Brett Cannon516592f2004-12-07 00:42:59 +00003045- setup.py now uses the directories specified in LDFLAGS using the -L option
3046 and in CPPFLAGS using the -I option for adding library and include
3047 directories, respectively, for compiling extension modules against. This has
3048 led to the core being compiled using the values in CPPFLAGS. It also removes
3049 the need for the special-casing of both DarwinPorts and Fink for darwin since
3050 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3051 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3052 Fink, ``-I/opt/local/include`` for DarwinPorts).
3053
Brett Cannon43802422005-02-10 20:48:03 +00003054- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3055 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3056 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3057 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003059C API
3060-----
3061
Tim Petersc9d78aa2006-03-26 23:27:58 +00003062- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3063 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3064 is obtained via the ``PyObject_`` family, it must be released via the
3065 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3066 always been officially true, but when Python's small-object allocator was
3067 introduced, an attempt was made to cater to a few extension modules
3068 discovered at the time that obtained memory via ``PyObject_New`` but
3069 released it via ``PyMem_DEL``. It's years later, and if such code still
3070 exists it will fail now (probably with segfaults, but calling wrong
3071 low-level memory management functions can yield many symptoms).
3072
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003073- Added a C API for set and frozenset objects.
3074

3076
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003077- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3078 mapping argument now. This string is used as a mapping table. Byte values
3079 greater than the length of the string and 0xFFFE are treated as undefined
3080 mappings.
