11
12Core and builtins
13-----------------
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Amaury Forgeot d'Arcafa0d582008-09-01 20:05:08 +000015- Issue #3751: str.rpartition would perform a left-partition when called with
16 a unicode argument.
17
Georg Brandl45c33ce2008-08-11 09:13:26 +000018- Issue #3537: Fix an assertion failure when an empty but presized dict
19 object was stored in the freelist.
20
Neal Norwitz4f3be8a2008-07-31 17:08:14 +000021- Apply security patches from Apple.
22
Neal Norwitz83ac0142008-07-28 05:06:20 +000023- Issue #2620: Overflow checking when allocating or reallocating memory
24 was not always being done properly in some python types and extension
25 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
26 all been updated to perform better checks and places in the code that
27 would previously leak memory on the error path when such an allocation
28 failed have been fixed.
29
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +000030- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
31 Windows / Visual Studio versions.
32
Mark Dickinsonab396e02008-07-16 11:04:17 +000033- Issue #3360: Fix incorrect parsing of '020000000000.0', which
34 produced a ValueError instead of giving the correct float.
35
Amaury Forgeot d'Arcceda6a62008-07-01 20:52:56 +000036- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
37 set to a custom object whose write() method happens to install
38 another file in sys.stdout.
39
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000040- Issue #3088: Corrected a race condition in classes derived from
41 threading.local: the first member set by a thread could be saved in
42 another thread's dictionary.
43
Amaury Forgeot d'Arc3255e132008-06-16 19:22:42 +000044- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
45 holds the last (strong) reference to its referent.
46
Guido van Rossumaa975432008-04-10 22:43:58 +000047- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
48 having a self-referential tuple, which is possible from C code. Nor did
49 object's tp_str consider that a type's tp_str could do something that could
50 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
51 respectively, fixed the issues. (Backport of r58288 from trunk.)
52
Georg Brandld9f1da02008-03-29 01:50:46 +000053- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
54 cannot be executed.
55
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000056- The compilation of a class nested in another class used to leak one
57 reference on the outer class name.
58
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000059- Issue #1477: With narrow Unicode builds, the unicode escape sequence
60 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
61 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
62 UTF-16 surrogates are generated in this case, like normal unicode literals
63 and the 'unicode-escape' codec.
64
Neal Norwitzb3635f92008-03-18 04:17:36 +000065- Issue #2321: use pymalloc for unicode object string data to reduce
66 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000067
Sean Reifscheider4af861c2008-03-20 17:39:31 +000068- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
69 bogus error messages.
70
Gregory P. Smith14acde32008-04-09 23:41:13 +000071- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
72 parameter but was not verifying that it was greater than zero. Values
73 less than zero will now raise a SystemError and return NULL to indicate a
74 bug in the calling C code.
75
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000076- Issue #2588, #2589: Fix potential integer underflow and overflow
77 conditions in the PyOS_vsnprintf C API function.
78

81-------
82
Thomas Heller275e2292008-08-19 17:17:37 +000083- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
84 api functions without holding the GIL, which could lead to a fatal
85 error when they failed.
86
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +000087- Issue #2234: distutils failed for some versions of the cygwin compiler. The
88 version reported by these tools does not necessarily follow the python
89 version numbering scheme, so the module is less strict when parsing it.
90
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +000091- Issue #2222: Fixed reference leak when occured os.rename()
92 fails unicode conversion on 2nd parameter. (windows only)
93

95
Robert Schuppenies78813dc2008-08-10 11:19:25 +000096- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
97 menu entries were not deleted.
98
Martin v. Löwisc7af7f32008-08-02 07:21:06 +000099- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
100
Brett Cannonff931572008-07-13 01:20:19 +0000101- Issue #3339: dummy_thread.acquire() could return None which is not a valid
102 return value.
103
Raymond Hettinger75ee9eb2008-06-16 01:49:18 +0000104- Issue #3116 and #1792: Fix quadratic behavior in marshal.dumps().
105
Thomas Hellerf3bb2832008-04-25 19:55:19 +0000106- Issue #2682: ctypes callback functions no longer contain a cyclic
107 reference to themselves.
108
Amaury Forgeot d'Arc8d904c32008-04-22 21:17:18 +0000109- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
110 handlers that derive the same default base class.
111
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +0000112- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
113 string literals; previously, ["" ""] was rendered as [""""], which is
114 incorrect python code.
115
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +0000116- Issue #2482: Make sure that the coefficient of a Decimal is always
117 stored as a str instance, not as a unicode instance. This ensures
118 that str(Decimal) is always an instance of str. This fixes a
119 regression from Python 2.5.1 to Python 2.5.2.
120
Mark Dickinson26c25d92008-03-25 14:35:25 +0000121- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

132 root directory, and also exclude .hg, .git, .bzr, and _darcs.
133
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +0000134- Bug #1389051: imaplib causes excessive memory fragmentation when reading
135 large messages.
136
Andrew M. Kuchling664553a2008-02-23 19:30:59 +0000137- Bug #1389051, 1092502: fix excessively large memory allocations when
Antoine Pitrouc8e4bed2008-07-25 19:00:48 +0000138 calling .read() on a socket object wrapped with makefile().

Gregory P. Smithf8f30fa2008-07-06 04:04:07 +0000147- Issue #2632: Prevent socket.read(bignumber) from over allocating memory
148 in the common case when the data is returned from the underlying socket
149 in increments much smaller than bignumber.
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +0000150
Gregory P. Smithb4bc9b92008-08-04 00:15:54 +0000151- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
152 argument in python 2.5, this broke code that subclassed Popen to include its
153 own poll method. Fixed my moving _deadstate to an _internal_poll method.
154
Gregory P. Smith7641b1c2008-08-04 03:23:25 +0000155- Issue #2113: Fix error in subprocess.Popen if the select system call is
156 interrupted by a signal.
157

159 up in the child process to prevent deadlock and report proper thread counts
160 if the new process uses the threading module.

Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000240 the condition is false. Now the compiler correctly emits bytecode for the
241 "else" suite.
242

Guido van Rossumc69ac252006-08-10 18:09:25 +00001193What's New in Python 2.5 release candidate 1?
1194=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001195
Anthony Baxterb4096662006-08-16 03:42:26 +00001196*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001197
1198Core and builtins
1199-----------------
1200
Neal Norwitz24b6f202006-09-05 04:43:56 +00001201- Fix infinite recursion when subclassing long and overriding __hash__.
1202
1203- Fix concatenation (+=) of long strings.
1204
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001205- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001206 compared equal or unequal to a string and a UnicodeDecodeError
1207 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001208
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001209 Instead, the equal (==) and unequal (!=) comparison operators will
1210 now issue a UnicodeWarning and interpret the two objects as
1211 unequal. The UnicodeWarning can be filtered as desired using
1212 the warning framework, e.g. silenced completely, turned into an
1213 exception, logged, etc.
1214
1215 Note that compare operators other than equal and unequal will still
1216 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001217
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001218- Fix segfault when doing string formatting on subclasses of long.
1219
1220- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1221 with new-style classes.
1222
1223- Fix bug related to __len__ functions returning negative values with
1224 classic classes.
1225
1226- Patch #1538606, Fix __index__() clipping. There were some problems
1227 discovered with the API and how integers that didn't fit into Py_ssize_t
1228 were handled. This patch attempts to provide enough alternatives
1229 to effectively use __index__.
1230
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001231- Bug #1536021: __hash__ may now return long int; the final hash
1232 value is obtained by invoking hash on the long int.
1233
Thomas Hellerab1049c2006-08-08 17:37:00 +00001234- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1235
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001236- Bug #1535165: fixed a segfault in input() and raw_input() when
1237 sys.stdin is closed.
1238
Thomas Heller74d36f02006-08-04 18:17:40 +00001239- On Windows, the PyErr_Warn function is now exported from
1240 the Python dll again.
1241
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001242- Bug #1191458: tracing over for loops now produces a line event
1243 on each iteration. Fixing this problem required changing the .pyc
1244 magic number. This means that .pyc files generated before 2.5c1
1245 will be regenerated.
1246
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001247- Bug #1333982: string/number constants were inappropriately stored
1248 in the byte code and co_consts even if they were not used, ie
1249 immediately popped off the stack.
1250
Georg Brandle9462c72006-08-04 18:03:37 +00001251- Fixed a reference-counting problem in property().
1252
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001253
1254Library
1255-------
1256
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001257- Fix a bug in the ``compiler`` package that caused invalid code to be
1258 generated for generator expressions.
1259
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001260- The distutils version has been changed to 2.5.0. The change to
1261 keep it programmatically in sync with the Python version running
1262 the code (introduced in 2.5b3) has been reverted. It will continue
1263 to be maintained manually as static string literal.
1264
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001265- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001266 and this cannot be converted to the required C type, an exception is
1267 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001268 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001269
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001270- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001271 an exception.
1272
Tim Peterscbdd3502006-09-05 01:47:53 +00001273- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001274 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001275 workarounds for clocks with low resolution, to stop the code yielding
1276 duplicate UUIDs.
1277
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001278- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1279 before raising SystemExit, allowing IDLE to honor quit() and exit().
1280
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001281- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1282
Georg Brandl7a1af772006-08-14 21:55:28 +00001283- Patch #1536071: trace.py should now find the full module name of a
1284 file correctly even on Windows.
1285
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001286- logging's atexit hook now runs even if the rest of the module has
1287 already been cleaned up.
1288
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001289- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001290
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001291- Bug #1531405, format_exception no longer raises an exception if
1292 str(exception) raised an exception.
1293
Neil Schemenauer06ded092006-08-04 16:20:30 +00001294- Fix a bug in the ``compiler`` package that caused invalid code to be
1295 generated for nested functions.
1296
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001297

1306 raises the correct exceptions.
1307
Thomas Heller1ce433e2006-08-14 16:20:04 +00001308- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1309 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1310
Thomas Heller86720042006-08-14 11:17:48 +00001311- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1312 uses the _as_parameter_ attribute when objects are passed to foreign
1313 function calls. The ctypes version number was changed to 1.0.1.
1314
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001315- Bug #1530559, struct.pack raises TypeError where it used to convert.
1316 Passing float arguments to struct.pack when integers are expected
1317 now triggers a DeprecationWarning.

Tim Peters4643c2f2006-08-10 22:45:34 +00001351C API
1352-----
1353
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001354- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1355
Tim Peters4643c2f2006-08-10 22:45:34 +00001356- Bug #1069160. Internal correctness changes were made to
1357 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1358 the documentation was changed to state that the return value
1359 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001362What's New in Python 2.5 beta 3?
1363================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001364
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001365*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001366
1367Core and builtins
1368-----------------
1369
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001370- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001371 returned a long (see PEP 353).
1372
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001373- Bug #1515471: string.replace() accepts character buffers again.
1374
Neal Norwitz07aadb12006-07-30 06:55:48 +00001375- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1376 This provides the proper warning for struct.pack().
1377 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1378
Neal Norwitz0d62a062006-07-30 06:53:31 +00001379- Patch #1531113: Fix augmented assignment with yield expressions.
1380 Also fix a SystemError when trying to assign to yield expressions.
1381
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001382- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1383 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1384 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1385 excessive filesystem operations during imports.
1386
Tim Petersbc24eee2006-07-27 01:14:53 +00001387- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1388 operations on signed longs that are formally undefined by C.
1389 Unfortunately, at least one compiler now cares about that, so complicated
1390 the code to make that compiler happy again.
1391
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001392- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1393
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001394- Patch #1232023: Stop including current directory in search
1395 path on Windows.
1396
Neal Norwitze1fdb322006-07-21 05:32:28 +00001397- Fix some potential crashes found with failmalloc.
1398
Neal Norwitze7563102006-07-17 01:00:16 +00001399- Fix warnings reported by Klocwork's static analysis tool.
1400
Neal Norwitz84be93b2006-07-16 01:50:38 +00001401- Bug #1512814, Fix incorrect lineno's when code within a function
1402 had more than 255 blank lines.
1403
Georg Brandl9dceedb2006-07-12 15:31:17 +00001404- Patch #1521179: Python now accepts the standard options ``--help`` and
1405 ``--version`` as well as ``/?`` on Windows.
1406
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001407- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001408 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001409 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001410
Tim Peters112aad32006-07-19 00:03:19 +00001411- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001412 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001413 new ``sys._current_frames()`` returns a dictionary with one entry,
1414 mapping the faux "thread id" 0 to the current frame.
1415
Ronald Oussoren3075e162006-07-25 20:28:55 +00001416- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001417
Ronald Oussoren3075e162006-07-25 20:28:55 +00001418
Neal Norwitza1f10902006-07-12 07:28:29 +00001419Library
1420-------
1421
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001422- Correction of patch #1455898: In the mbcs decoder, set final=False
1423 for stream decoder, but final=True for the decode function.
1424
Georg Brandl07fec3a2006-08-01 18:49:24 +00001425- os.urandom no longer masks unrelated exceptions like SystemExit or
1426 KeyboardInterrupt.
1427
Tim Peters4643c2f2006-08-10 22:45:34 +00001428- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001429 shutil.copytree on Windows
1430
Georg Brandle34ac7c2006-07-30 11:07:23 +00001431- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1432 refers to file descriptors, not file objects.
1433
Tim Peterscbdd3502006-09-05 01:47:53 +00001434- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001435 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001436 #1513611, and probably others.
1437
Georg Brandledd9b0d2006-07-29 09:33:26 +00001438- Bug #1441397: The compiler module now recognizes module and function
1439 docstrings correctly as it did in Python 2.4.
1440
Tim Peters6f681472006-07-27 23:44:37 +00001441- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1442 lost that tests are sorted by name before being run. This rarely
1443 matters for well-written tests, but can create baffling symptoms if
1444 side effects from one test to the next affect outcomes. ``DocTestFinder``
1445 has been changed to sort the list of tests it returns.

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001447- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001448 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001449
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001450- Bug #978833: Really close underlying socket in _socketobject.close.
1451
Georg Brandldb232dc2006-08-20 13:15:43 +00001452- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1453 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001454
Georg Brandlcf0c1722006-07-26 07:23:32 +00001455- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1456 to recursive calls and call it with the failing package name.
1457
Martin v. Löwis0b483032006-07-25 09:53:12 +00001458- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1459
Georg Brandlc13c34c2006-07-24 14:09:56 +00001460- Patch #1515343: Fix printing of deprecated string exceptions with a
1461 value in the traceback module.
1462
Greg Ward48fae7a2006-07-23 16:05:51 +00001463- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1464
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001465- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1466
Brett Cannoncaebe222006-07-18 04:41:36 +00001467- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1468 argument tuple. For arguments where zero is illegal, the value is forced to
1469 the minimum value that is correct. This is to support an undocumented but
1470 common way people used to fill in inconsequential information in the time
1471 tuple pre-2.4.
1472
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001473- Patch #1220874: Update the binhex module for Mach-O.
1474
Barry Warsawb110bad2006-07-21 14:51:07 +00001475- The email package has improved RFC 2231 support, specifically for
1476 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1477 (name*0=<blah>) parameter continuations. This may change the types of
1478 values returned from email.message.Message.get_param() and friends.
1479 Specifically in some cases where non-encoded continuations were used,
1480 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1481 will just return the string (since non-encoded continuations don't have
1482 charset and language parts).
1483
1484 Also, whereas % values were decoded in all parameter continuations, they are
1485 now only decoded in encoded parameter parts.
1486
Ronald Oussoren3075e162006-07-25 20:28:55 +00001487- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1488
1489- Bug #1517996: IDLE now longer shows the default Tk menu when a
1490 path browser, class browser or debugger is the frontmost window on MacOS X
1491
Barry Warsaw00decd72006-07-27 23:43:15 +00001492- Patch #1520294: Support for getset and member descriptors in types.py,
1493 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1494 of an object against these built-in types and more importantly, for getting
1495 their docstrings printed in the interactive interpreter's help() function.

1499-----------------
1500
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001501- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1502 a socket operation on a socket with a timeout, the exception will be
1503 caught correctly. Previously, the exception was not caught.
1504
Thomas Heller1393d6a2006-07-28 21:43:20 +00001505- Patch #1529514: The _ctypes extension is now compiled on more
1506 openbsd target platforms.
1507
Tim Peters9cab5932006-07-28 00:30:00 +00001508- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1509 a memory leak, affecting pickles and deep copies.
1510
Tim Petersbc24eee2006-07-27 01:14:53 +00001511- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1515
Thomas Hellerce049a02006-07-14 17:51:14 +00001516- Patch #1521817: Index range checking on ctypes arrays containing
1517 exactly one element enabled again. This allows iterating over these
1518 arrays, without the need to check the array size before.
1519
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001520- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001521 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001522 /dev/null in certain cases; this is now fixed.
1523
Thomas Heller47d7a062006-07-12 08:43:47 +00001524- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1525 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001526
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001527- Because of a misspelled preprocessor symbol, ctypes was always
1528 compiled without thread support; this is now fixed.
1529
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001530- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1531 methods now allow their database parameter to be None as the
1532 sleepycat API allows.
1533
Matt Flemingec926502006-07-28 11:27:27 +00001534- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1535 bluetooth API compared with Linux and FreeBSD.
1536
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001537Tests
1538-----
1539
1540- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1541 how long the test file should take to play. Now accepts taking 2.93 secs
1542 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1543
Georg Brandl4793aa32006-07-28 18:31:39 +00001544- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1545 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1546 run via ``regrtest.py``. Now they do.

1550
1551- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1552
Ronald Oussoren26cad082006-08-01 21:00:57 +00001553Mac
1554---
1555
1556- PythonLauncher now works correctly when the path to the script contains
1557 characters that are treated specially by the shell (such as quotes).
1558
1559- Bug #1527397: PythonLauncher now launches scripts with the working directory
1560 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001561 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001562 expect.

1571-----------------
1572
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001573- Bug #1441486: The literal representation of -(sys.maxint - 1)
1574 again evaluates to a int object, not a long.
1575
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001576- Bug #1501934: The scope of global variables that are locally assigned
1577 using augmented assignment is now correctly determined.
1578
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001579- Bug #927248: Recursive method-wrapper objects can now safely
1580 be released.
1581
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001582- Bug #1417699: Reject locale-specific decimal point in float()
1583 and atof().
1584
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001585- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1586 omit a default "error" argument for NULL pointer. This allows
1587 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001588
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001589- Bug #1519018: 'as' is now validated properly in import statements.
1590
Neal Norwitz28746ab2006-07-09 22:14:42 +00001591- On 64 bit systems, int literals that use less than 64 bits are
1592 now ints rather than longs.
1593
Neal Norwitzed657552006-07-10 00:04:44 +00001594- Bug #1512814, Fix incorrect lineno's when code at module scope
1595 started after line 256.
1596
Tim Peters32a83612006-07-10 21:08:24 +00001597- New function ``sys._current_frames()`` returns a dict mapping thread
1598 id to topmost thread stack frame. This is for expert use, and is
1599 especially useful for debugging application deadlocks. The functionality
1600 was previously available in Fazal Majid's ``threadframe`` extension
1601 module, but it wasn't possible to do this in a wholly threadsafe way from
1602 an extension.
1603

Martin v. Löwis8d656812006-07-10 07:23:48 +00001613 environment variable to be set in order to the SDK environment
1614 for finding the compiler, include files, etc.

1619
Thomas Woutersadd19112006-07-05 11:03:49 +00001620- string.Template() now correctly handles tuple-values. Previously,
1621 multi-value tuples would raise an exception and single-value tuples would
1622 be treated as the value they contain, instead.
1623
Martin v. Löwisede77f52006-07-03 13:01:35 +00001624- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1626
Martin v. Löwis45482392006-07-03 12:28:58 +00001627- Bug #1267547: Put proper recursive setup.py call into the
1628 spec file generated by bdist_rpm.
1629
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001630- Bug #1514693: Update turtle's heading when switching between
1631 degrees and radians.
1632
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001633- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001634 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001635
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001636- Bug #1514703: Only setup canvas window in turtle when the canvas
1637 is created.
1638
Martin v. Löwis7596e832006-07-01 15:33:37 +00001639- Bug #1513223: .close() of a _socketobj now releases the underlying
1640 socket again, which then gets closed as it becomes unreferenced.
1641
Fred Drake10497c82006-06-29 02:57:48 +00001642- Bug #1504333: Make sgmllib support angle brackets in quoted
1643 attribute values.
1644
1645- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1646 sgmllib ('[' and ']' were not accepted).
1647
Georg Brandl1be63af2006-06-28 20:23:25 +00001648- Fix a bug in the turtle module's end_fill function.
1649
Brett Cannon53ab5b72006-06-22 16:49:14 +00001650- Bug #1510580: The 'warnings' module improperly required that a Warning
1651 category be either a types.ClassType and a subclass of Warning. The proper
1652 check is just that it is a subclass with Warning as the documentation states.
1653
Georg Brandlad29e632006-06-21 17:45:17 +00001654- The compiler module now correctly compiles the new try-except-finally
1655 statement (bug #1509132).
1656
Neal Norwitz60373cd2006-06-22 06:30:50 +00001657- The wsgiref package is now installed properly on Unix.
1658
Vinay Sajip28e57612006-07-01 10:45:20 +00001659- A bug was fixed in logging.config.fileConfig() which caused a crash on
1660 shutdown when fileConfig() was called multiple times.
1661
Gerhard Häring762fbd32006-07-02 17:48:30 +00001662- The sqlite3 module did cut off data from the SQLite database at the first
1663 null character before sending it to a custom converter. This has been fixed
1664 now.
1665
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001666Extension Modules
1667-----------------
1668
Tim Peters112aad32006-07-19 00:03:19 +00001669- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1670 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1671 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001672
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001673- Assigning None to pointer type fields in ctypes structures possible
1674 overwrote the wrong fields, this is fixed now.
1675
1676- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1677 on non-Windows platforms.
1678
1679- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1680 integer or long, without range checking.
1681
1682- Patch #1517790: It is now possible to use custom objects in the ctypes
1683 foreign function argtypes sequence as long as they provide a from_param
1684 method, no longer is it required that the object is a ctypes type.
1685
1686- The '_ctypes' extension module now works when Python is configured
1687 with the --without-threads option.
1688
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001689- Bug #1513646: os.access on Windows now correctly determines write
1690 access, again.

1704
Tim Peters32a83612006-07-10 21:08:24 +00001705- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001706 Previously, the slight difference could cause compilation errors of the
1707 'zlib' module on systems with more than one version of zlib.
1708
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001709- The MSI compileall step was fixed to also support a TARGETDIR
1710 with spaces in it.

1728 documentation for the warnings module.
1729
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001730- Patch #1509163: MS Toolkit Compiler no longer available.

Georg Brandla56b9152006-06-19 06:35:54 +00001743- Patch #1507676: Error messages returned by invalid abstract object operations
1744 (such as iterating over an integer) have been improved and now include the
1745 type of the offending object to help with debugging.
1746
Brett Cannonea3912b2006-06-13 21:46:41 +00001747- Bug #992017: A classic class that defined a __coerce__() method that returned
1748 its arguments swapped would infinitely recurse and segfault the interpreter.
1749
Neal Norwitz909eb122006-06-12 02:13:21 +00001750- Fix the socket tests so they can be run concurrently.
1751
Neal Norwitzb9845e72006-06-12 02:11:18 +00001752- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001753 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001754
Brett Cannon22565aa2006-06-09 22:31:23 +00001755- Bug #532646: object.__call__() will continue looking for the __call__
1756 attribute on objects until one without one is found. This leads to recursion
1757 when you take a class and set its __call__ attribute to an instance of the
1758 class. Originally fixed for classic classes, but this fix is for new-style.
1759 Removes the infinite_rec_3 crasher.
1760
Georg Brandl24250812006-06-09 18:45:48 +00001761- The string and unicode methods startswith() and endswith() now accept
1762 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1763
Brett Cannonde3b0522006-06-08 17:00:45 +00001764- Buffer objects, at the C level, never used the char buffer
1765 implementation even when the char buffer for the wrapped object was
1766 explicitly requested (originally returned the read or write buffer).
1767 Now a TypeError is raised if the char buffer is not present but is
1768 requested.
1769
Georg Brandlddbaa662006-06-04 21:56:52 +00001770- Patch #1346214: Statements like "if 0: suite" are now again optimized
1771 away like they were in Python 2.4.
1772
Georg Brandlb7c8f542006-05-27 12:30:25 +00001773- Builtin exceptions are now full-blown new-style classes instead of
1774 instances pretending to be classes, which speeds up exception handling
1775 by about 80% in comparison to 2.5a2.
1776
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001777- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1778 Unicode 4.1.
1779
Georg Brandlf4ef1162006-05-26 18:03:31 +00001780- Patch #921466: sys.path_importer_cache is now used to cache valid and
1781 invalid file paths for the built-in import machinery which leads to
1782 fewer open calls on startup.
1783
Tim Peters696cf432006-05-24 21:10:40 +00001784- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1785 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1786 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1787 the number of input digits (it was and remains linear-time for bases
1788 2, 4, 8, 16 and 32).
1789
Tim Petersb713ec22006-05-23 18:45:30 +00001790- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1791 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1792 an integer close to ``sys.maxint``. This was repaired by patch
1793 #1335972, which also gives a nice speedup.
1794
Richard Jonescebbefc2006-05-23 18:28:17 +00001795- Patch #1337051: reduced size of frame objects.
1796
1797- PyErr_NewException now accepts a tuple of base classes as its
1798 "base" parameter.
1799
Richard Jones7c88dcc2006-05-23 10:37:38 +00001800- Patch #876206: function call speedup by retaining allocated frame
1801 objects.
1802
Georg Brandl7b90e162006-05-18 07:01:27 +00001803- Bug #1462152: file() now checks more thoroughly for invalid mode
1804 strings and removes a possible "U" before passing the mode to the
1805 C library function.
1806
Neal Norwitz1004a532006-05-15 07:17:23 +00001807- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1808
Neal Norwitz373f0a72006-05-15 07:04:36 +00001809- Bug #1487966: Fix SystemError with conditional expression in assignment
1810
Martin v. Löwis879768d2006-05-11 13:28:43 +00001811- WindowsError now has two error code attributes: errno, which carries
1812 the error values from errno.h, and winerror, which carries the error
1813 values from winerror.h. Previous versions put the winerror.h values
1814 (from GetLastError()) into the errno attribute.
1815
Martin v. Löwis77736712006-05-04 05:51:03 +00001816- Patch #1475845: Raise IndentationError for unexpected indent.
1817
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001818- Patch #1479181: split open() and file() from being aliases for each other.
1819
Tim Peters44bd9862006-06-01 13:49:23 +00001820- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1821 methods were always silently ignored by dictionaries when comparing keys.
1822 They are now passed through (except when using the C API function
1823 ``PyDict_GetItem()``, whose semantics did not change).
1824
1825- Bug #1456209: In some obscure cases it was possible for a class with a
1826 custom ``__eq__()`` method to confuse dict internals when class instances
1827 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1828 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001830Extension Modules
1831-----------------
1832
Trent Mick960a3f82006-06-28 20:30:41 +00001833- Bug #1295808: expat symbols should be namespaced in pyexpat
1834
1835- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1836
Brett Cannon6ee7d012006-06-08 16:23:04 +00001837- Change binascii.hexlify to accept a read-only buffer instead of only a char
1838 buffer and actually follow its documentation.
1839
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001840- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1841
Nick Coghlanc649ec52006-05-29 12:43:05 +00001842- Patch #1478788 (modified version): The functional extension module has
1843 been renamed to _functools and a functools Python wrapper module added.
1844 This provides a home for additional function related utilities that are
1845 not specifically about functional programming. See PEP 309.
1846
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001847- Patch #1493701: performance enhancements for struct module.
1848
Georg Brandl378d5922006-05-17 14:26:50 +00001849- Patch #1490224: time.altzone is now set correctly on Cygwin.
1850
Georg Brandl8d3342b2006-05-16 07:38:27 +00001851- Patch #1435422: zlib's compress and decompress objects now have a
1852 copy() method.
1853
Andrew MacIntyre92913322006-06-13 15:04:24 +00001854- Patch #1454481: thread stack size is now tunable at runtime for thread
1855 enabled builds on Windows and systems with Posix threads support.
1856
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001857- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1858 (up to the system limit of 32K characters).
1859
1860- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1861 As a result, these functions now raise WindowsError instead of OSError.
1862
Tim Peters7a822da2006-05-25 21:50:17 +00001863- ``time.clock()`` on Win64 should use the high-performance Windows
1864 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1865 Windows platforms).
1866
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001867- Calling Tk_Init twice is refused if the first call failed as that
1868 may deadlock.
1869
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001870- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1871 accept it without potentially using an uninitialized pointer.
1872
1873- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1874 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1875 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001876
Gregory P. Smith372b5832006-06-05 18:48:21 +00001877- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001878 [pybsddb project SF patch number 1466734]
1879
Gregory P. Smith372b5832006-06-05 18:48:21 +00001880- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1881 parameter is supplied. [SF pybsddb bug #1477863]
1882
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001883- bsddb: the __len__ method of a DB object has been fixed to return correct
1884 results. It could previously incorrectly return 0 in some cases.
1885 Fixes SF bug 1493322 (pybsddb bug 1184012).
1886
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001887- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1888 aborts the db transaction safely when a modifier callback fails.
1889 Fixes SF python patch/bug #1408584.
1890
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001891- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001892 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001893 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1894 database calls that would previously deadlock. [SF python bug #775414]
1895
Vinay Sajip28e57612006-07-01 10:45:20 +00001896- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001897
Walter Dörwald4994d952006-06-19 08:07:50 +00001898- Patch #1506645: add Python wrappers for the curses functions
1899 is_term_resized, resize_term and resizeterm.

1903
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001904- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1905 functions.
1906
Martin v. Löwis3798da02006-06-17 18:44:27 +00001907- Patch #812986: Update turtle output even if not tracing.
1908
Vinay Sajip28e57612006-07-01 10:45:20 +00001909- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001910 Tkinter.BaseWidget.
1911
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001912- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1913
Martin v. Löwis337487e2006-06-17 09:15:14 +00001914- Patch #763580: Add name and value arguments to Tkinter variable
1915 classes.
1916
Georg Brandl83cc0d02006-06-14 08:50:03 +00001917- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1918 mime.types file for determining MIME types.
1919
Georg Brandl2605ca82006-06-14 06:08:31 +00001920- Bug #1339007: Shelf objects now don't raise an exception in their
1921 __del__ method when initialization failed.
1922
Martin v. Löwisd8251432006-06-14 05:21:04 +00001923- Patch #1455898: The MBCS codec now supports the incremental mode for
1924 double-byte encodings.
1925
Tim Peters43898b42006-06-14 04:09:25 +00001926- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1927 guarantee that adjacent triples in the return list always describe
1928 non-adjacent blocks. Previously, a pair of matching blocks could end
1929 up being described by multiple adjacent triples that formed a partition
1930 of the matching pair.
1931
Greg Ward0e0c9f42006-06-11 16:24:11 +00001932- Bug #1498146: fix optparse to handle Unicode strings in option help,
1933 description, and epilog.
1934
Greg Wardd1c797e2006-06-11 14:42:41 +00001935- Bug #1366250: minor optparse documentation error.
1936
Greg Ward7f547402006-06-11 00:40:49 +00001937- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1938 clarify docs.
1939
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001940- The wsgiref package has been added to the standard library.
1941
Nick Coghlan676725d2006-06-08 13:54:49 +00001942- The functions update_wrapper() and wraps() have been added to the functools
1943 module. These make it easier to copy relevant metadata from the original
1944 function when writing wrapper functions.
1945
Tim Petersd6a9eef2006-06-05 01:48:21 +00001946- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1947 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001948
Martin v. Löwis3f767792006-06-04 19:36:28 +00001949- Patch #1359618: Speed up charmap encoder by using a trie structure
1950 for lookup.
1951
Tim Petersd609b1a2006-06-02 23:22:51 +00001952- The functions in the ``pprint`` module now sort dictionaries by key
1953 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1954 if and only if its display required more than one line, although that
1955 wasn't documented. The new behavior increases predictability; e.g.,
1956 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1957
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001958- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1959 (thanks for J. J. Lee).
1960
Georg Brandl2b330372006-05-28 20:23:12 +00001961- Patch #1496206: improve urllib2 handling of passwords with respect to
1962 default HTTP and HTTPS ports.
1963
George Yoshidaf3c65de2006-05-28 16:39:09 +00001964- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1965
Bob Ippolito7298f272006-05-23 18:43:47 +00001966- Patch #1281707: speed up gzip.readline.
1967
Georg Brandlb89316f2006-05-17 15:51:16 +00001968- Patch #1180296: Two new functions were added to the locale module:
1969 format_string() to get the effect of "format % items" but locale-aware,
1970 and currency() to format a monetary number with currency sign.
1971
Georg Brandle3a25832006-05-17 14:56:04 +00001972- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1973 and several features added, such as speed and geometry control.
1974
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001975- Patch #1488881: add support for external file objects in bz2 compressed
1976 tarfiles.
1977
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001978- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1979 stdout arguments, making it possible to redirect input and output
1980 for remote debugging.
1981
1982- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1983 a couple of issues, notably handling of long file names using the
1984 GNU LONGNAME extension.
1985
1986- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1987 new flag when ``name`` is already the name of an option flag.
1988
1989- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1990 package.
1991
1992- Patch #1472854: make the rlcompleter.Completer class usable on non-
1993 UNIX platforms.
1994
1995- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1996
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001997- Bug #1472827: correctly escape newlines and tabs in attribute values in
1998 the saxutils.XMLGenerator class.

2034-----------------
2035
Thomas Heller1b046642006-04-18 18:51:06 +00002036- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2037 by converting these apis from macros into exported functions again:
2038
2039 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile

2044
Martin v. Löwis45294a92006-04-18 06:24:08 +00002045- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2046
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002047- All uses of PyStructSequence_InitType have been changed to initialize
2048 the type objects only once, even if the interpreter is initialized
2049 multiple times.
2050
Neal Norwitz61546162006-04-14 05:20:28 +00002051- Bug #1454485, array.array('u') could crash the interpreter. This was
2052 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2053 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2054
2055- Py_UNICODE is unsigned. It was always documented as unsigned, but
2056 due to a bug had a signed value in previous versions.
2057
Tim Peters3a5e8b12006-04-11 01:44:07 +00002058- Patch #837242: ``id()`` of any Python object always gives a positive
2059 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2060 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002061 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002062 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002063
Tim Peters3a5e8b12006-04-11 01:44:07 +00002064 def __hash__(self):
2065 return id(self) # WRONG
2066
2067 because a hash result must be a (short) Python int but it was always
2068 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002069 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002070 was always usable as a hash value before this patch. That's no longer
2071 necessarily so.
2072
2073- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002074 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002075 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002076 #1454844)
2077
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002078- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2079 involving generators that have paused outside of any ``try`` or ``with``
2080 blocks. (In 2.5a1, a paused generator that was part of a reference
2081 cycle could not be garbage collected, regardless of whether it was
2082 paused in a ``try`` or ``with`` block.)

2089
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002090- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2091 fails with an error condition.
2092
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002093- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2094
2095- Bug #1117761: bsddb.*open() no longer raises an exception when using
2096 the cachesize parameter.
2097
2098- Bug #1149413: bsddb.*open() no longer raises an exception when using
2099 a temporary db (file=None) with the 'n' flag to truncate on open.
2100
2101- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2102 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002103
Armin Rigoa9017c32006-04-19 11:50:27 +00002104- Patch #1062014: AF_UNIX sockets under Linux have a special
2105 abstract namespace that is now fully supported.
2106

2108-------
2109
Peter Astrand7d1d4362006-07-14 14:04:45 +00002110- Bug #1223937: subprocess.CalledProcessError reports the exit status
2111 of the process using the returncode attribute, instead of
2112 abusing errno.
2113
Tim Peters711bf302006-04-25 03:31:36 +00002114- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2115 a doctest to be skipped (the code is not run, and the expected output
2116 or exception is ignored).
2117
Nick Coghlanda2268f2006-04-24 04:37:15 +00002118- Fixed contextlib.nested to cope with exceptions being raised and
2119 caught inside exit handlers.
2120
Greg Wardab05edc2006-04-23 03:47:58 +00002121- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2122 hex, octal, or binary; add ``append_const`` action; keep going if
2123 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2124 added ``epilog`` for better help generation).
2125
Tim Peters21fbd572006-04-21 21:18:10 +00002126- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2127 called from a thread spawned as a side effect of importing a module.
2128
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002129- The pydoc module now supports documenting packages contained in
2130 .zip or .egg files.
2131
2132- The pkgutil module now has several new utility functions, such
2133 as ``walk_packages()`` to support working with packages that are either
2134 in the filesystem or zip files.
2135
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002136- The mailbox module can now modify and delete messages from
2137 mailboxes, in addition to simply reading them. Thanks to Gregory
2138 K. Johnson for writing the code, and to the 2005 Google Summer of
2139 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002140
Tim Petersc7605f22006-04-17 21:12:33 +00002141- The ``__del__`` method of class ``local`` in module ``_threading_local``
2142 returned before accomplishing any of its intended cleanup.

2149
Anthony Baxtere29002c2006-04-12 12:07:31 +00002150- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2151 Windows. Bug #1469163.
2152
Phillip J. Eby47032112006-04-11 01:07:43 +00002153- The warnings, linecache, inspect, traceback, site, and doctest modules
2154 were updated to work correctly with modules imported from zipfiles or
2155 via other PEP 302 __loader__ objects.
2156
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002157- Patch #1467770: Reduce usage of subprocess._active to processes which

2163
Skip Montanaro262fb922006-04-21 02:31:07 +00002164- The pstats.Stats class accepts an optional stream keyword argument to
2165 direct output to an alternate file-like object.
2166
Anthony Baxter51bcb682006-04-05 14:51:42 +00002167Build
2168-----
2169
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002170- The Makefile now has a reindent target, which runs reindent.py on
2171 the library.
2172
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002173- Patch #1470875: Building Python with MS Free Compiler
2174
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002175- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002176
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002177- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2178 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002179 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002180 CXX from --with-cxx-main, see description in README.
2181
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002182- Patch #1429775: Link extension modules with the shared libpython.
2183
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002184- Fixed a libffi build problem on MIPS systems.
2185
Tim Peters8931ff12006-05-13 23:28:20 +00002186- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2187 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2188 and "%zu" for unsigned integers of type ``size_t``.
2189
Anthony Baxter51bcb682006-04-05 14:51:42 +00002190Tests
2191-----
2192
Nick Coghlanda2268f2006-04-24 04:37:15 +00002193- test_contextlib now checks contextlib.nested can cope with exceptions
2194 being raised and caught inside exit handlers.
2195
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002196- test_cmd_line now checks operation of the -m and -c command switches
2197
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002198- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2199 it separately and by hand. It also wasn't cleaning up its changes to
2200 the current Decimal context.
2201
Thomas Woutersabd08882006-04-26 15:53:30 +00002202- regrtest.py now has a -M option to run tests that test the new limits of
2203 containers, on 64-bit architectures. Running these tests is only sensible
2204 on 64-bit machines with more than two gigabytes of memory. The argument
2205 passed is the maximum amount of memory for the tests to use.

2214-------------
2215
Tim Petersb06d28c2006-05-12 01:57:59 +00002216- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2217
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002218- PEP 343: Added Context Types section to the library reference
2219 and attempted to bring other PEP 343 related documentation into
2220 line with the implementation and/or python-dev discussions.
2221
Tim Peters8dc73d22006-04-24 02:03:16 +00002222- Bug #1337990: clarified that ``doctest`` does not support examples
2223 requiring both expected output and an exception.

2227=================================
2228
Anthony Baxterebed3f62006-04-03 15:03:44 +00002229*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002230
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002231Core and builtins
2232-----------------
2233
Nick Coghlan43832302006-04-23 17:04:07 +00002234- PEP 338: -m command line switch now delegates to runpy.run_module
2235 allowing it to support modules in packages and zipfiles
2236
Martin v. Löwisc661b882006-04-20 04:54:23 +00002237- On Windows, .DLL is not an accepted file name extension for
2238 extension modules anymore; extensions are only found if they
2239 end in .PYD.
2240
Martin v. Löwisea62d252006-04-03 10:56:49 +00002241- Bug #1421664: sys.stderr.encoding is now set to the same value as
2242 sys.stdout.encoding.
2243
Neal Norwitz92e212f2006-04-03 04:48:37 +00002244- __import__ accepts keyword arguments.
2245
Georg Brandlccadf842006-03-31 18:54:53 +00002246- Patch #1460496: round() now accepts keyword arguments.
2247
Anthony Baxter262c00a2006-03-30 10:53:17 +00002248- Fixed bug #1459029 - unicode reprs were double-escaped.
2249
Hye-Shik Changd478f342006-03-23 12:32:36 +00002250- Patch #1396919: The system scope threads are reenabled on FreeBSD
2251 5.4 and later versions.
2252
Neal Norwitze98ccf62006-03-23 05:39:47 +00002253- Bug #1115379: Compiling a Unicode string with an encoding declaration
2254 now gives a SyntaxError.
2255
Georg Brandlabd1ff82006-03-18 07:59:59 +00002256- Previously, Python code had no easy way to access the contents of a
2257 cell object. Now, a ``cell_contents`` attribute has been added
2258 (closes patch #1170323).
2259
Tim Peterscf79aac2006-03-16 01:14:46 +00002260- Patch #1123430: Python's small-object allocator now returns an arena to
2261 the system ``free()`` when all memory within an arena becomes unused
2262 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2263 freed. Some applications will see a drop in virtual memory size now,
2264 especially long-running applications that, from time to time, temporarily
2265 use a large number of small objects. Note that when Python returns an
2266 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002267 platform C library will in turn return that memory to the operating system.
2268 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002269 appears to be effective at least on Microsoft C and gcc-based systems.
2270 Thanks to Evan Jones for hard work and patience.
2271
Georg Brandl533ff6f2006-03-08 18:09:27 +00002272- Patch #1434038: property() now uses the getter's docstring if there is
2273 no "doc" argument given. This makes it possible to legitimately use
2274 property() as a decorator to produce a read-only property.
2275
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002276- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2277 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2278 of requiring an int or long in slicing and a few other contexts, enabling
2279 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2280
Neal Norwitz995acdf2006-03-07 05:01:00 +00002281- Fixed various bugs reported by Coverity's Prevent tool.
2282
Brett Cannonbf364092006-03-01 04:25:17 +00002283- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2284 new exception base class, BaseException, which has a new message attribute.
2285 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2286 Raising a string exception now raises a DeprecationWarning.
2287
Thomas Woutersfb609f42006-02-28 16:37:25 +00002288- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2289 explicitly relative, using 'from .module import name' to mean 'from the same
2290 package as this module is in. Imports without dots still default to the
2291 old relative-then-absolute, unless 'from __future__ import
2292 absolute_import' is used.
2293
Brett Cannona7446e32006-02-27 23:39:10 +00002294- Properly check if 'warnings' raises an exception (usually when a filter set
2295 to "error" is triggered) when raising a warning for raising string
2296 exceptions.
2297
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002298- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002299 The name was removed from Include/code.h.
2300
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002301- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002302
Guido van Rossum1968ad32006-02-25 22:38:04 +00002303- Patch 1433928:
2304 - The copy module now "copies" function objects (as atomic objects).
2305 - dict.__getitem__ now looks for a __missing__ hook before raising
2306 KeyError.
2307
Tim Peters84ef21c2006-02-28 20:39:06 +00002308- PEP 343: with statement implemented. Needs ``from __future__ import
2309 with_statement``. Use of 'with' as a variable will generate a warning.
2310 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002311 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002312 The following objects have __context__ methods:
2313 - The built-in file type.
2314 - The thread.LockType type.
2315 - The following types defined by the threading module:
2316 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2317 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002318
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002319- Fix the encodings package codec search function to only search
2320 inside its own package. Fixes problem reported in patch #1433198.
2321
2322 Note: Codec packages should implement and register their own
2323 codec search function. PEP 100 has the details.
2324
Tim Peters9ea89d22006-06-04 03:26:02 +00002325- PEP 353: Using ``Py_ssize_t`` as the index type.
2326
2327- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2328 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2329 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2330 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2331 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002332
Neal Norwitzfc76d632006-01-10 06:03:13 +00002333- Patch #1400181, fix unicode string formatting to not use the locale.
2334 This is how string objects work. u'%f' could use , instead of .
2335 for the decimal point. Now both strings and unicode always use periods.
2336
Neal Norwitz671b9e32006-01-09 07:07:12 +00002337- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2338 configure would break checking curses.h.
2339
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002340- Bug #959576: The pwd module is now builtin. This allows Python to be
2341 built on UNIX platforms without $HOME set.
2342
Neal Norwitzc10978f2005-12-19 06:07:16 +00002343- Bug #1072182, fix some potential problems if characters are signed.
2344
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002345- Bug #889500, fix line number on SyntaxWarning for global declarations.
2346
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002347- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2348
Neal Norwitze7214a12005-12-18 05:03:17 +00002349- Support for converting hex strings to floats no longer works.
2350 This was not portable. float('0x3') now raises a ValueError.
2351
Barry Warsaw2a38a862005-12-18 01:27:35 +00002352- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002353 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002354 is now displayed in interactive prompt banner.
2355
Georg Brandlfa166682005-12-17 21:45:17 +00002356- Implementation of PEP 341 - Unification of try/except and try/finally.
2357 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002358 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002359
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002360- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2361 now encodes backslash correctly.
2362
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002363- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2364
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002365- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002366 and long longs.
2367
Neal Norwitz67715f02005-11-09 06:59:35 +00002368- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002369 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002370 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002371
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002372- Replaced most Unicode charmap codecs with new ones using the
2373 new Unicode translate string feature in the builtin charmap
2374 codec; the codecs were created from the mapping tables available
2375 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2376 encodings now include a mapping for the Apple logo)
2377
Tim Peterse3547fd2005-12-16 23:13:57 +00002378- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002379
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002380- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002381
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002382- A new AST parser implementation was completed. The abstract
2383 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002384 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002385
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002386- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002387 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2388
Neal Norwitz708e51a2005-10-03 04:48:15 +00002389- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2390
Neal Norwitz11bd1192005-10-03 00:54:56 +00002391- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2392 Provide a warning when a directory is passed on the command line.
2393
Neal Norwitz40d37812005-10-02 01:48:49 +00002394- Fix segfault with invalid coding.
2395
2396- SF bug #772896: unknown encoding results in MemoryError.
2397
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002398- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002399 supported a __len__() method which evaluated to False when the iterator
2400 was empty.
2401
Guido van Rossum630db602005-09-20 18:49:54 +00002402- On 64-bit platforms, when __len__() returns a value that cannot be
2403 represented as a C int, raise OverflowError.
2404
Skip Montanarof8948ca2005-09-19 03:54:46 +00002405- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002406 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002407
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002408- SF bug #893549: parsing keyword arguments was broken with a few format
2409 codes.
2410
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002411- Changes donated by Elemental Security to make it work on AIX 5.3
2412 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2413 bug #105470: test_pwd fails on 64bit system (Opteron).
2414
Guido van Rossum539c6622005-09-14 17:49:54 +00002415- Changes donated by Elemental Security to make it work on HP-UX 11 on
2416 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2417
Georg Brandl4550b8d2005-08-26 06:43:52 +00002418- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002419 (fixes bug #1119418).
2420
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002421- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2422
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002423- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2424 exceptions that cause a function to exit.
2425
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002426- The implementation of set() and frozenset() was revised to use its
2427 own internal data structure. Memory consumption is reduced by 1/3
2428 and there are modest speed-ups as well. The API is unchanged.
2429
Tim Petersde7990b2005-07-17 23:45:23 +00002430- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2431
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002432- SF bug #1229429: PyObject_CallMethod failed to decrement some
2433 reference counts in some error exit cases.
2434
Tim Petersecc6e6a2005-07-10 22:30:55 +00002435- SF bug #1185883: Python's small-object memory allocator took over
2436 a block managed by the platform C library whenever a realloc specified
2437 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002438 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002439 portable way to copy data from the C-managed block into Python's
2440 small-object space without risking a memory fault. Python's small-object
2441 realloc now leaves such blocks under the control of the platform C
2442 realloc.
2443
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002444- SF bug #1232517: An overflow error was not detected properly when
2445 attempting to convert a large float to an int in os.utime().
2446
Raymond Hettinger3296e692005-06-29 23:29:56 +00002447- SF bug #1224347: hex longs now print with lowercase letters just
2448 like their int counterparts.
2449
Michael W. Hudson188d4362005-06-20 16:52:57 +00002450- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2451 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2452 interpreter states; back out that fix and do a better job (see
2453 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2454 for a longer write-up of the problem).
2455
Michael W. Hudsondf888462005-06-03 14:41:55 +00002456- SF patch #1180995: marshal now uses a binary format by default when
2457 serializing floats.
2458
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002459- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2460 the routines that promise to produce IEEE 754 binary representations
2461 of floats now simply copy bytes around.
2462
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002463- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2464 278.
2465
Brett Cannonc3647ac2005-04-26 03:45:26 +00002466- patch #1109424: int, long, float, complex, and unicode now check for the
2467 proper magic slot for type conversions when subclassed. Previously the
2468 magic slot was ignored during conversion. Semantics now match the way
2469 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002470 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002471 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002472 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002473
Barry Warsawc8d907c2005-04-19 23:43:40 +00002474- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2475 NULL, now raise an AttributeError when attempting to set or delete the
2476 attribute. Previously a TypeError was raised, but this was inconsistent
2477 with the equivalent pure-Python implementation.
2478
Michael W. Hudson774479c2005-04-18 08:46:17 +00002479- It is now safe to call PyGILState_Release() before
2480 PyEval_InitThreads() (note that if there is reason to believe there
2481 are multiple threads around you still must call PyEval_InitThreads()
2482 before using the Python API; this fix is for extension modules that
2483 have no way of knowing if Python is multi-threaded yet).
2484
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002485- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2486 disabled caused a crash.
2487
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002488- Bug #1165306: instancemethod_new allowed the creation of a method
2489 with im_class == im_self == NULL, which caused a crash when called.
2490
Tim Petersecc6e6a2005-07-10 22:30:55 +00002491- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002492 fixes the crash seen in bug #1165761
2493
Raymond Hettinger96229b12005-03-11 06:49:40 +00002494- Added two new builtins, any() and all().
2495
Brett Cannon409d8f22005-03-05 06:47:57 +00002496- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002497 (e.g., ``class C(): pass`` is no longer a syntax error).
2498 Patch #1176012 added support to the 'parser' module and 'compiler' package
2499 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002500
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002501- Patch #1115086: Support PY_LONGLONG in structmember.
2502
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002503- Bug #1155938: new style classes did not check that __init__() was
2504 returning None.
2505
Tim Petersecc6e6a2005-07-10 22:30:55 +00002506- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002507 ('\') with a specific error message.
2508
Martin v. Löwisff232d72005-03-03 09:24:38 +00002509- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2510
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002511- Bug #1124295: the __name__ attribute of file objects was
2512 inadvertently made inaccessible in restricted mode.
2513
Tim Petersecc6e6a2005-07-10 22:30:55 +00002514- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002515 an ferror() call.
2516
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002517- min() and max() now support key= arguments with the same meaning as in
2518 list.sort().
2519
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002520- The peephole optimizer now performs simple constant folding in expressions:
2521 (2+3) --> (5).
2522
Raymond Hettingera422c342005-01-11 03:03:27 +00002523- set and frozenset objects can now be marshalled. SF #1098985.
2524
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002525- Bug #1077106: Poor argument checking could cause memory corruption
2526 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002527
Jeremy Hyltonab630502005-02-04 18:44:06 +00002528- The parser did not complain about future statements in illegal
2529 positions. It once again reports a syntax error if a future
2530 statement occurs after anything other than a doc string.
2531
Neil Schemenauercf52c072005-08-12 17:34:58 +00002532- Change the %s format specifier for str objects so that it returns a
2533 unicode instance if the argument is not an instance of basestring and
2534 calling __str__ on the argument returns a unicode instance.
2535
Tim Petersf4e69282006-02-27 17:15:31 +00002536- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2537 current thread state when the auto-GIL-state machinery knows about
2538 it (since the thread state is being deleted, continuing to remember it
2539 can't help, but can hurt if another thread happens to get created with
2540 the same thread id).
2541
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002542Extension Modules
2543-----------------
2544
Georg Brandl43f08a82006-03-31 18:01:16 +00002545- Patch #1380952: fix SSL objects timing out on consecutive read()s
2546
Neal Norwitz05a45592006-03-20 06:30:08 +00002547- Patch #1309579: wait3 and wait4 were added to the posix module.
2548
Anthony Baxterfa869072006-03-20 05:21:58 +00002549- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2550 In addition, the existing ulaw code was updated.
2551
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002552- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002553 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002554
Neal Norwitz10be10c2006-03-16 06:50:13 +00002555- Everything under lib-old was removed. This includes the following modules:
2556 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002557 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002558 util, whatsound, whrandom, zmod
2559
2560- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2561
2562- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002563 is deprecated. The undocumented re.engine variable no longer exists.
2564
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002565- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2566 SS2 (single-shift 2) escape sequences correctly.
2567
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002568- The unicodedata module was updated to the 4.1 version of the Unicode
2569 database. The 3.2 version is still available as unicodedata.db_3_2_0
2570 for applications that require this specific version (such as IDNA).
2571
Neal Norwitzb62c4332006-03-04 18:35:47 +00002572- The timing module is no longer built by default. It was deprecated
2573 in PEP 4 in Python 2.0 or earlier.
2574
Guido van Rossum1968ad32006-02-25 22:38:04 +00002575- Patch 1433928: Added a new type, defaultdict, to the collections module.
2576 This uses the new __missing__ hook behavior added to dict (see above).
2577
Georg Brandldbd83392006-02-20 09:42:33 +00002578- Bug #854823: socketmodule now builds on Sun platforms even when
2579 INET_ADDRSTRLEN is not defined.
2580
Georg Brandlf4f44152006-02-18 22:29:33 +00002581- Patch #1393157: os.startfile() now has an optional argument to specify
2582 a "command verb" to invoke on the file.
2583
Neal Norwitz082b2df2006-02-07 07:04:46 +00002584- Bug #876637, prevent stack corruption when socket descriptor
2585 is larger than FD_SETSIZE.
2586
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002587- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2588 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2589 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2590
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002591- Patch #1422385: The nis module now supports access to domains other
2592 than the system default domain.
2593
Martin v. Löwis14694662006-02-03 12:54:16 +00002594- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2595 are reported, the limit on path name lengths is removed, and stat reports
2596 WindowsError now (instead of OSError).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002732- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2733 been renamed to have only a single underscore prefix. This was done to
2734 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002735
Nick Coghlan43832302006-04-23 17:04:07 +00002736- PEP 338: new module runpy defines a run_module function to support
2737 executing modules which provide access to source code or a code object
2738 via the PEP 302 import mechanisms.
2739
Anthony Baxter93f5b932006-04-03 08:05:07 +00002740- The email module's parsedate_tz function now sets the daylight savings

2748 in attribute values.
2749
Anthony Baxterc51ee692006-04-01 00:57:31 +00002750- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002751 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002752 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002753 module will not be built.
2754
Tim Petersc17976e2006-04-01 00:26:53 +00002755- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2756 aren't officially supported here, and trying to use them will probably
2757 raise an exception some day. But dicts have been allowed, and "mostly
2758 worked", so support for them won't go away without warning.
2759
Georg Brandl338ef7d2006-03-31 18:42:16 +00002760- Bug #1445068: getpass.getpass() can now be given an explicit stream

2778
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002779- email 4.0 package now integrated. This is largely the same as the email 3.0
2780 package that was included in Python 2.3, except that PEP 8 module names are
2781 now used (e.g. mail.message instead of email.Message). The MIME classes
2782 have been moved to a subpackage (e.g. email.mime.text instead of
2783 email.MIMEText). The old names are still supported for now. Several
2784 deprecated Message methods have been removed and lots of bugs have been
2785 fixed. More details can be found in the email package documentation.
2786
Walter Dörwald40108c92006-03-27 08:15:44 +00002787- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2788 (a subclass of tuple) that provides incremental decoders and encoders
2789 (a way to use stateful codecs without the stream API). Python functions
2790 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2791 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2792 have been added.

2795 a ValueError instead of a StopIteration now (like file and cString.String do).
2796 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2797 called before (like file and StringIO.StringIO do).

2865
Neal Norwitz338e7862005-12-23 21:27:46 +00002866- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2867 LoadError as documented, instead of IOError. For compatibility,
2868 LoadError subclasses IOError.
2869
Brett Cannon3cbd0382005-12-16 22:49:23 +00002870- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002871 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2872 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2873 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2874 Ronald L. Rivest offered this advice for Python:
2875
2876 "The consensus of researchers in this area (at least as
2877 expressed at the NIST Hash Function Workshop 10/31/05),
2878 is that SHA-256 is a good choice for the time being, but
2879 that research should continue, and other alternatives may
2880 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002881
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002882- Added a subset of Fredrik Lundh's ElementTree package. Available

Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002926 separator and do not output trailing semicolon.
Georg Brandl532efab2005-08-24 22:34:21 +00002927
Georg Brandlb9256022005-08-24 18:46:39 +00002928- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2929 ContentTooShortException, when the actually downloaded size does not
2930 match the Content-Length header.

2935 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002936 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002937

2951
Georg Brandla4a8b822005-07-15 09:13:21 +00002952- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2953 parameter, but uses the usual "kwargs=None".
2954
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002955- textwrap now processes text chunks at O(n) speed instead of O(n**2).

2957
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002958- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2959 to W3C name (404 -> 'Not Found'). RFE #1216944.
2960
Georg Brandl9e43acf2005-07-04 17:16:07 +00002961- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2962 as this can cause problems with apps closing all file descriptors.

2975 Bug #1224621.
2976
Raymond Hettinger68c04532005-06-10 11:05:19 +00002977- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002978 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002979 the generate_tokens() function now accepts a callable argument that
2980 terminates by raising StopIteration.
2981
Georg Brandl9166e1a2005-06-04 09:20:03 +00002982- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2986
Skip Montanaro174dd222005-05-14 20:54:16 +00002987- Patch #1120353: The xmlrpclib module provides better, more transparent,
2988 support for datetime.{datetime,date,time} objects. With use_datetime set
2989 to True, applications shouldn't have to fiddle with the DateTime wrapper
2990 class at all.
2991
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002992- distutils.commands.upload was added to support uploading distribution

2994
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002995- distutils.commands.register now encodes the data as UTF-8 before posting
2996 them to PyPI.
2997
Raymond Hettinger267b8682005-03-27 10:47:39 +00002998- decimal operator and comparison methods now return NotImplemented
2999 instead of raising a TypeError when interacting with other types. This
3000 allows other classes to implement __radd__ style methods and have them
3001 work as expected.
3002
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003003- Bug #1163325: Decimal infinities failed to hash. Attempting to
3004 hash a NaN raised an InvalidOperation instead of a TypeError.
3005
Tim Petersecc6e6a2005-07-10 22:30:55 +00003006- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003007 stream compression; add, for symmetry reasons, r:* as a synonym of r.

3040
Guido van Rossumd0641422005-02-03 15:01:24 +00003041- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3042 disables recursive traversal through instance attributes, which can
3043 be exploited in various ways.
3044
Tim Peterse3547fd2005-12-16 23:13:57 +00003045- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003046 flags on the HTTP listening socket.
3047
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003048- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3049 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3050
Fred Drakefbdeaad2006-07-29 16:56:15 +00003051- Patches #893642, #1039083: add allow_none, encoding arguments to
3052 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003053

Thomas Hellerd6c6e222005-01-20 19:20:16 +00003056- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3057
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003058- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3059
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003060- Enhancements to the csv module:
3061
3062 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003063 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003064 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003065 + Dialect parameter parsing has been re-implemented to improve error
3066 reporting.
3067 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3068 dictates.
3069 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003070 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003071 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003072 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3073 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003074 + reader now allows \r characters to be quoted (previously it only allowed
3075 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003076 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003077 + Dialect classes passed to the module are no longer instantiated by
3078 the module before being parsed (the former validation scheme required
3079 this, but the mechanism was unreliable).
3080 + The dialect registry now contains instances of the internal
3081 C-coded dialect type, rather than references to python objects.
3082 + the internal c-coded dialect type is now immutable.
3083 + register_dialect now accepts the same keyword dialect specifications
3084 as the reader and writer, allowing the user to register dialects
3085 without first creating a dialect class.
3086 + a configurable limit to the size of parsed fields has been added -
3087 previously, an unmatched quote character could result in the entire
3088 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003089 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003090 the parser field size limit (returning the former limit). The initial
3091 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003092 + A line_num attribute has been added to the reader object, which tracks
3093 the number of lines read from the source iterator. This is not
3094 the same as the number of records returned, as records can span
3095 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003096 + reader and writer objects were not being registered with the cyclic-GC.
3097 This has been fixed.
3098
Brett Cannone6539c42005-01-08 02:43:53 +00003099- _DummyThread objects in the threading module now delete self.__block that is
3100 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3101 lock primitives tend to be limited in number and thus should not be wasted on
3102 a _DummyThread object. Fixes bug #1089632.
3103
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003104- The imghdr module now detects Exif files.
3105
Raymond Hettinger6065d322004-12-20 23:51:53 +00003106- StringIO.truncate() now correctly adjusts the size attribute.
3107 (Bug #951915).
3108
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003109- locale.py now uses an updated locale alias table (built using
3110 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3111 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003112 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003113
Raymond Hettinger3557f422004-12-07 12:02:02 +00003114- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3115
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003116- the pickle module no longer accepts the deprecated None option in the
3117 args tuple returned by __reduce__().
3118
Brett Cannon84667c02004-12-07 03:25:18 +00003119- optparse now optionally imports gettext. This allows its use in setup.py.
3120
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003121- the pickle module no longer uses the deprecated bin parameter.
3122

3128
Raymond Hettinger664347b2004-12-04 21:21:53 +00003129- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3130 extended or overridden by subclasses. Formerly, the subclassed method would
3131 be ignored by the rest of the module. (Bug #1078905).
3132
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003133- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003134 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003135
Walter Dörwald36733692004-12-22 12:50:50 +00003136- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3137 once when a size argument is given. This prevents a buffer overflow in the
3138 tokenizer with very long source lines.
3139
Barry Warsaw538561e2006-01-01 21:48:54 +00003140- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3141 immediately after creating the object, without any intervening
3142 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003143
Skip Montanaro05885812005-01-16 20:48:27 +00003144- The reconvert.quote function can now emit triple-quoted strings. The
3145 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003146
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003147- ``UserString.MutableString`` now supports negative indices in
3148 ``__setitem__`` and ``__delitem__``
3149
Greg Ward40407942005-03-05 02:53:17 +00003150- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3151 correctly.
3152
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003153- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3154 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3155 character even if the user has passed a size parameter to get a proper
3156 line ending. Remove the special handling of a "\r\n" that has been split
3157 between two lines.
3158
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003159- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3160 about illegal code points. The codec now supports PEP 293 style error
3161 handlers.
3162
Walter Dörwald78a78b02005-09-01 12:04:29 +00003163- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003164 from the input stream, so that the output is a byte string in the correct
3165 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003166
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003167- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3168 considering it exactly like a '*'.
3169
Walter Dörwald007f8df2005-10-09 19:42:27 +00003170- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3171 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003172
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003173- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3174
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003175- Patch #1413711: Certain patterns of differences were making difflib
3176 touch the recursion limit.
3177
Walter Dörwald58917a62006-03-31 15:26:22 +00003178- Bug #947906: An object oriented interface has been added to the calendar
3179 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003180 called as a script (e.g. via ``python -mcalendar``). Localized month and
3181 weekday names can be ouput (even if an exotic encoding is used) using
3182 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003184Build
3185-----
3186
Neal Norwitz602d3392006-03-31 08:21:40 +00003187- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3188 by using -mieee gcc option.
3189

3191
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003192- Build support for Win64-AMD64 was added.
3193
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003194- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3195
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003196- Patch #881820: look for openpty and forkpty also in libbsd.
3197
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003198- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3199 The zlib module is now builtin on Windows.
3200
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003201- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3202
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003203- Bug #1189330: configure did not correctly determine the necessary
3204 value of LINKCC if python was built with GCC 4.0.
3205
Trent Mick8321b422005-07-26 02:29:21 +00003206- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3207 vulnerability in zlib 1.2.1 and 1.2.2.
3208
Brett Cannon08cd5982005-04-24 22:26:38 +00003209- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3210 flags that change binary compatibility. Changes were also made to
3211 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003212 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003213
Bob Ippolitoed233462005-03-29 13:47:59 +00003214- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3215 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3216 no longer exists). This configure patch makes things right.
3217
Martin v. Löwise2713be2005-03-08 15:03:08 +00003218- Bug #1158607: Build with --disable-unicode again.
3219
Brett Cannon46d96232005-02-16 00:07:19 +00003220- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3221 defined. Discovered as a result of not being able to build on OS X.
3222
Brett Cannon516592f2004-12-07 00:42:59 +00003223- setup.py now uses the directories specified in LDFLAGS using the -L option
3224 and in CPPFLAGS using the -I option for adding library and include
3225 directories, respectively, for compiling extension modules against. This has
3226 led to the core being compiled using the values in CPPFLAGS. It also removes
3227 the need for the special-casing of both DarwinPorts and Fink for darwin since
3228 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3229 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3230 Fink, ``-I/opt/local/include`` for DarwinPorts).
3231
Brett Cannon43802422005-02-10 20:48:03 +00003232- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3233 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3234 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3235 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003237C API
3238-----
3239
Tim Petersc9d78aa2006-03-26 23:27:58 +00003240- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3241 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3242 is obtained via the ``PyObject_`` family, it must be released via the
3243 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3244 always been officially true, but when Python's small-object allocator was
3245 introduced, an attempt was made to cater to a few extension modules
3246 discovered at the time that obtained memory via ``PyObject_New`` but
3247 released it via ``PyMem_DEL``. It's years later, and if such code still
3248 exists it will fail now (probably with segfaults, but calling wrong
3249 low-level memory management functions can yield many symptoms).
3250
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003251- Added a C API for set and frozenset objects.
3252
Raymond Hettinger66517482004-12-03 11:45:13 +00003253- Removed PyRange_New().
3254
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003255- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3256 mapping argument now. This string is used as a mapping table. Byte values
3257 greater than the length of the string and 0xFFFE are treated as undefined
3258 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003265
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003266- Patch #1276356: New resource "urlfetch" is implemented. This enables
3267 even impatient people to run tests that require remote files.
