12Core and builtins
13-----------------
14
Christian Heimeseebb79c2008-01-03 22:32:26 +000015- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
16 functions.
Christian Heimese2ca4242008-01-03 20:23:15 +000017
Christian Heimes0a8143f2007-12-18 23:22:54 +000018- Issue #1635: Platform independent creation and representation of NaN
19 and INF. float("nan"), float("inf") and float("-inf") now work on every
20 platform with IEEE 754 semantics.
21
Raymond Hettingerfd7ed402007-12-18 21:24:09 +000022- Compiler now generates simpler and faster code for dictionary literals.
23 The oparg for BUILD_MAP now indicates an estimated dictionary size.
24 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
25
Christian Heimesdb3d6cb2007-12-16 21:39:43 +000026- Issue #1638: %zd configure test fails on Linux
27
Christian Heimes90e10e72007-12-14 02:35:23 +000028- Issue #1620: New property decorator syntax was modifying the decorator
29 in place instead of creating a new decorator object.
30
Christian Heimes284d9272007-12-10 22:28:56 +000031- Issue #1580: New free format floating point representation based on
32 "Floating-Point Printer Sample Code", by Robert G. Burger. For example
33 repr(11./5) now returns '2.2' instead of '2.2000000000000002'.
34
Skip Montanaro26015492007-12-08 15:33:24 +000035- Issue #1538: Avoid copying string in split/rsplit if the split
36 char is not found.
37
Andrew M. Kuchling395fe442007-12-05 13:27:20 +000038- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +000039 SystemError.
40
Nick Coghlanef01d822007-12-03 12:55:17 +000041- PEP 366: Allow explicit relative imports when executing modules
42 inside packages with the -m switch via a new module level
43 __package__ attribute.
44
Christian Heimesdfdfaab2007-12-01 11:20:10 +000045- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
46 ``PyFloat_GetInfo()`` to the float API.
47
Amaury Forgeot d'Arcdafd32b2007-11-30 20:51:40 +000048- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
49 format code incorrectly truncated the length to an int, even when
50 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
51 results with huge strings.
52
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +000053- Issue #1402: Fix a crash on exit, when another thread is still running, and
54 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
55 PyGILState_Release() functions.
56
Christian Heimes28104c52007-11-27 23:16:44 +000057- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
58
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +000059- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
60 attribute of an empty cell object.
61
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +000062- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
63 It now correctly saves its state between chunks of data.
64
Nick Coghlan327a39b2007-11-18 11:56:28 +000065- Patch #1739468: Directories and zipfiles containing a __main__.py file can
66 now be directly executed by passing their name to the interpreter. The
67 directory/zipfile is automatically inserted as the first entry in sys.path.
68
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +000069- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
70 generator expression when at the same time the executed code is closing a
71 paused generator.
72
Raymond Hettinger1760c8a2007-11-08 02:52:43 +000073- sets and frozensets now have an isdisjoint() method.
74
Raymond Hettinger3f8caa32007-10-24 01:28:33 +000075- optimize the performance of builtin.sum().
76
Neal Norwitz44f326e2007-10-05 05:29:17 +000077- Fix warnings found by the new version of the Coverity checker.
78
Raymond Hettinger8f669372007-10-03 21:18:11 +000079- The enumerate() builtin function is no longer bounded to sequences smaller
80 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
81 shifts from ints to longs.
82
Brett Cannon0b14f242007-09-30 19:45:10 +000083- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
84 having a self-referential tuple, which is possible from C code. Nor did
85 object's tp_str consider that a type's tp_str could do something that could
86 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
87 respectively, fixed the issues.
88
Brett Cannon01531592007-09-17 03:28:34 +000089- Issue #1164: It was possible to trigger deadlock when using the 'print'
90 statement to write to a file since the GIL was not released as needed. Now
91 PyObject_Print() does the right thing along with various tp_print
92 implementations of the built-in types and those in the collections module.
93
Brett Cannon4c20bc42007-09-11 21:02:28 +000094- Issue #1147: Exceptions were directly allowing string exceptions in their
95 throw() method even though string exceptions no longer allowed.
96
Brett Cannona0c05512007-09-10 21:38:27 +000097- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
98 list by using the recursion counter.
99
Brett Cannon1e534b52007-09-07 04:18:30 +0000100- Issue #1202533: Fix infinite recursion calls triggered by calls to
101 PyObject_Call() never calling back out to Python code to trigger recursion
102 depth updates/checks. Required the creation of a static RuntimeError
103 instance in case normalizing an exception put the recursion check value past
104 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
105
Martin v. Löwisa5136192007-09-04 14:19:28 +0000106- Patch #1031213: Decode source line in SyntaxErrors back to its original source
107 encoding.
108
Neal Norwitz766d8802007-08-03 06:46:29 +0000109- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
110
Martin v. Löwis68192102007-07-21 06:55:02 +0000111- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
112 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
113 PyVarObject_HEAD_INIT.
114
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000115- Patch #1673759: add a missing overflow check when formatting floats
116 with %G.
117
Martin v. Löwis6371cd82007-06-09 07:42:52 +0000118- Patch #1733960: Allow T_LONGLONG to accept ints.
119
Walter Dörwald84a3efe2007-06-13 16:57:12 +0000120- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
121
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000122- Prevent expandtabs() on string and unicode objects from causing a segfault
123 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000124
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000125- Bug #1733488: Fix compilation of bufferobject.c on AIX.
126
Georg Brandl25497a12007-06-01 19:20:27 +0000127- Bug #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +0000128
Neal Norwitz0ac60192007-05-27 04:08:54 +0000129- Add new attribute names for function objects. All the func_* become
130 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
131
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000132- Add -3 option to the interpreter to warn about features that are
133 deprecated and will be changed/removed in Python 3.0.
134
Georg Brandl2134e752007-05-21 20:34:16 +0000135- Patch #1686487: you can now pass any mapping after '**' in function
136 calls.
137
Collin Winter62903052007-05-18 23:11:24 +0000138- except clauses may now be spelled either "except E, target:" or
139 "except E as target:". This is to provide forwards compatibility with
140 Python 3.0.
141
Brett Cannon229cee22007-05-05 01:34:02 +0000142- Deprecate BaseException.message as per PEP 352.
143
Armin Rigo9790a272007-05-02 19:23:31 +0000144- Bug #1303614: don't expose object's __dict__ when the dict is
145 inherited from a builtin base.
146
Vinay Sajip8549ce32007-05-06 17:53:37 +0000147- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000148 setting a plain string, ie don't expand to single letter identifiers.
149
Raymond Hettinger13936692007-04-11 18:40:58 +0000150- Request #1191699: Slices can now be pickled.
151
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000152- Request #1193128: str.translate() now allows a None argument for
153 translations that only remove characters without re-mapping the
154 remaining characters.
155
Georg Brandl5cb76c12007-03-21 09:00:39 +0000156- Patch #1682205: a TypeError while unpacking an iterable is no longer
157 masked by a generic one with the message "unpack non-sequence".
158
Neal Norwitzaa754b72007-03-21 06:39:48 +0000159- Remove unused file Python/fmod.c.
160
Guido van Rossum143b5642007-03-23 04:58:42 +0000161- Bug #1683368: The object.__init__() and object.__new__() methods are
162 now stricter in rejecting excess arguments. The only time when
163 either allows excess arguments is when it is not overridden and the
164 other one is. For backwards compatibility, when both are
165 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000166 warning later). Also, type.__init__() insists on the same signature
167 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000168
Georg Brandl2b869942007-03-17 16:08:45 +0000169- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
170 to complex using its __complex__() method before falling back to the
171 __float__() method. Therefore, the functions in the cmath module now
172 can operate on objects that define a __complex__() method.
173
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000174- Patch #1623563: allow __class__ assignment for classes with __slots__.
175 The old and the new class are still required to have the same slot names.
176
Collin Winter77c67bd2007-03-16 04:11:30 +0000177- Patch #1642547: Fix an error/crash when encountering syntax errors in
178 complex if statements.
179
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000180- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
181 is called with an object that is faking its type.
182
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000183- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
184 name.
185
Georg Brandl5240d742007-03-13 20:46:32 +0000186- Patch #1444529: the builtin compile() now accepts keyword arguments.
187
Georg Brandl7b9c5552007-03-12 14:30:05 +0000188- Bug #1678647: write a newline after printing an exception in any
189 case, even when converting the value to a string failed.
190
Georg Brandl871f1bc2007-03-12 13:17:36 +0000191- The dir() function has been extended to call the __dir__() method on
192 its argument, if it exists. If not, it will work like before. This allows
193 customizing the output of dir() in the presence of a __getattr__().
194
Collin Winter276887b2007-03-12 16:11:39 +0000195- Patch #922167: Python no longer segfaults when faced with infinitely
196 self-recursive reload() calls (as reported by bug #742342).
197
Žiga Seilnacht89032082007-03-11 15:54:54 +0000198- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
199
Collin Wintere38051d2007-03-09 20:33:07 +0000200- Patch #1491866: change the complex() constructor to allow parthensized
201 forms. This means complex(repr(x)) now works instead of raising a
202 ValueError.
203
Georg Brandlaa2321b2007-03-07 00:40:28 +0000204- Patch #703779: unset __file__ in __main__ after running a file. This
205 makes the filenames the warning module prints much more sensible when
206 a PYTHONSTARTUP file is used.
207
Georg Brandl49aafc92007-03-07 00:34:46 +0000208- Variant of patch #697613: don't exit the interpreter on a SystemExit
209 exception if the -i command line option or PYTHONINSPECT environment
210 variable is given, but break into the interactive interpreter just like
211 on other exceptions or normal program exit.
212
Georg Brandl00cd8182007-03-06 18:41:12 +0000213- Patch #1638879: don't accept strings with embedded NUL bytes in long().
214
Georg Brandl098cd692007-03-06 12:17:50 +0000215- Bug #1674503: close the file opened by execfile() in an error condition.
216
Georg Brandl0fca97a2007-03-05 22:28:08 +0000217- Patch #1674228: when assigning a slice (old-style), check for the
218 sq_ass_slice instead of the sq_slice slot.
219
Neal Norwitz88516a62007-02-26 22:41:45 +0000220- When printing an unraisable error, don't print exceptions. before the name.
221 This duplicates the behavior whening normally printing exceptions.
222
Martin v. Löwisfd963262007-02-09 12:19:32 +0000223- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
224
Brett Cannon129bd522007-01-30 21:34:36 +0000225- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
226 catch a string exception raises DeprecationWarning.
227
Brett Cannonf5bee302007-01-23 23:21:22 +0000228- Bug #1377858: Fix the segfaulting of the interpreter when an object created
229 a weakref on itself during a __del__ call for new-style classes (classic
230 classes still have the bug).
231
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000232- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
233 frame's thread state.
234
Thomas Wouters6ed19652007-01-23 13:50:49 +0000235- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
236
Martin v. Löwis4885e7d2007-01-19 06:42:22 +0000237- Bug #1637022: Prefix AST symbols with _Py_.
238
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000239- Prevent seg fault on shutdown which could occur if an object
240 raised a warning.
241
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000242- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
243 to avoid relying on atexit.
244
Raymond Hettinger94547f72006-12-20 06:42:06 +0000245- Bug #1590891: random.randrange don't return correct value for big number
246
Georg Brandl283a1352006-11-19 08:48:30 +0000247- Patch #1586791: Better exception messages for some operations on strings,
248 tuples and lists.
249

Neal Norwitz85dbec62006-11-04 19:25:22 +0000254- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
255
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000256- Bug #1576657: when setting a KeyError for a tuple key, make sure that
257 the tuple isn't used as the "exception arguments tuple".
258
Neal Norwitz21997af2006-10-28 21:19:07 +0000259- Bug #1565514, SystemError not raised on too many nested blocks.
260
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000261- Bug #1576174: WindowsError now displays the windows error code
262 again, no longer the posix error code.
263
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000264- Patch #1549049: Support long values in structmember, issue warnings
265 if the assigned value for structmember fields gets truncated.
266
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000267- Update the peephole optimizer to remove more dead code (jumps after returns)
268 and inline unconditional jumps to returns.
269
Georg Brandl2c1375c2006-10-12 11:27:59 +0000270- Bug #1545497: when given an explicit base, int() did ignore NULs
271 embedded in the string to convert.
272
Georg Brandl846f73a2006-10-08 07:11:54 +0000273- Bug #1569998: break inside a try statement (outside a loop) is now
274 recognized and rejected.
275
Armin Rigo7ccbca92006-10-04 12:17:45 +0000276- list.pop(x) accepts any object x following the __index__ protocol.
277
278- Fix some leftovers from the conversion from int to Py_ssize_t
279 (relevant to strings and sequences of more than 2**31 items).
280
281- A number of places, including integer negation and absolute value,
282 were fixed to not rely on undefined behaviour of the C compiler
283 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000284
Georg Brandl3267d282006-09-30 09:03:42 +0000285- Bug #1566800: make sure that EnvironmentError can be called with any
286 number of arguments, as was the case in Python 2.4.
287
Georg Brandl5d59c092006-09-30 08:43:30 +0000288- Patch #1567691: super() and new.instancemethod() now don't accept
289 keyword arguments any more (previously they accepted them, but didn't
290 use them).
291
Georg Brandla10d3af2006-09-24 12:35:36 +0000292- Fix a bug in the parser's future statement handling that led to "with"
293 not being recognized as a keyword after, e.g., this statement:
294 from __future__ import division, with_statement
295

Collin Winterfaaa2042007-03-10 03:35:34 +0000613 be equal to calling getsockname() on the server's socket. Fixed by

Georg Brandl2c94bf72006-09-24 10:36:01 +0000878- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because

906
Neal Norwitz92422fb2006-08-18 03:57:54 +0000907Extension Modules
908-----------------

941 time so that opening a database previously created with the DB_DUP or
942 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
943 Specifically: dictionary assignment to a DB object will replace all
944 values for a given key when the database allows duplicate values.
945 DB users should use DB.put(k, v) when they want to store duplicates; not
946 DB[k] = v.
947

Christian Heimes000a0742008-01-03 22:16:32 +00001154- Issue #1726: Remove Python/atof.c from PCBuild/pythoncore.vcproj
1155
1156- Removed PCbuild8/ directory and added a new build directory for VS 2005
1157 based on the VS 2008 build directory to PC/VS8.0. The script
1158 PCbuild/vs8to9.py was added to sync changes from PCbuild to PC/VS8.0.
1159
1160- Moved PCbuild/ directory for VS 2003 to PC/VS7.1 and renamed PCBuild9/
1161 directory to PCBuild/.

1164
Guido van Rossum7c862f82007-12-13 20:50:10 +00001165- Bug #1608: use -fwrapv when GCC supports it. This is important,
1166 newer GCC versions may optimize away overflow buffer overflow checks
1167 without this option!
1168
Martin v. Löwis63bf1492007-11-12 05:14:05 +00001169- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
1170
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00001171- Add a FAST_LOOPS build option that speeds-up looping by trading away
1172 periodic threadstate and signal checking in tight loops. By default,
1173 this option is turned-off. It should only be enabled in debugged,
1174 performance critical applications.
1175
Martin v. Löwisd44a4e92007-09-05 11:47:34 +00001176- Patch #786737: Allow building in a tree of symlinks pointing to

1186
Georg Brandldb846032007-03-31 18:56:11 +00001187- Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS
1188 returned by python-config if Python was built with --enable-shared
1189 because that prevented the shared library from being used.
1190
Georg Brandl18c47f62007-03-13 10:19:22 +00001191- Patch #1569798: fix a bug in distutils when building Python from a
1192 directory within sys.exec_prefix.
1193
Martin v. Löwiseb623572007-03-12 10:50:39 +00001194- Bug #1675511: Use -Kpic instead of -xcode=pic32 on Solaris/x86.
1195
Martin v. Löwis4d542ec2006-11-25 15:39:19 +00001196- Disable _XOPEN_SOURCE on NetBSD 1.x.
1197

1199 attribute.
1200
Vinay Sajip76fdb8c2006-12-14 08:53:55 +00001201- Bug #1578513: Cross compilation was broken by a change to configure.
Martin v. Löwisfefbc202006-10-17 18:59:23 +00001202 Repair so that it's back to how it was in 2.4.3.
1203
Martin v. Löwisc9e82f62006-10-15 07:54:40 +00001204- Patch #1576954: Update VC6 build directory; remove redundant
1205 files in VC7.

1208
Neal Norwitz4bc2c092006-09-05 02:57:01 +00001209- Patch #1540470, for OpenBSD 4.0.
1210
Matthias Klosed149d0c2006-12-03 17:16:41 +00001211- Fix build failure on kfreebsd and on the hurd.
1212
Matthias Kloseebde1492006-12-09 12:15:27 +00001213- Fix the build of the library reference in info format.
1214

Matthias Klose642ac852007-09-04 18:17:36 +00001217- Makefile.pre.in(buildbottest): Run an optional script pybuildbot.identify
1218 to include some information about the build environment.
1219
Neal Norwitz92422fb2006-08-18 03:57:54 +00001220C API
1221-----
1222
Christian Heimes000a0742008-01-03 22:16:32 +00001223- Added a new API function ``PyImport_ImportModuleNoBlock``.
1224
1225- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
1226 imports. In earlier versions they might have used relative imports under
1227 some conditions.
1228
1229- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
1230 and Py_REFCNT.
1231
1232- Added case insensitive comparsion methods ``PyOS_stricmp(char*, char*)``
1233 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
1234
Neal Norwitz8a267062006-08-19 04:25:29 +00001235- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
1236 so it can be used as an expression.

1242- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE
1243 and _CRT_NONSTDC_NO_DEPRECATE.
1244
Martin v. Löwisd476a402007-10-12 08:56:52 +00001245- Bug #1216: Restore support for Visual Studio 2002.

1252
Brett Cannon791d56f2007-05-31 19:40:42 +00001253- buildtools now raises a DeprecationWarning.
1254
Brett Cannon5e263512007-05-20 23:17:38 +00001255- Removed the macfs module. It had been deprecated since Python 2.5. This
1256 lead to the deprecation of macostools.touched() as it relied solely on macfs
1257 and was a no-op under OS X.

1266-----------------
1267
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001268- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001269 compared equal or unequal to a string and a UnicodeDecodeError
1270 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001271
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001272 Instead, the equal (==) and unequal (!=) comparison operators will
1273 now issue a UnicodeWarning and interpret the two objects as
1274 unequal. The UnicodeWarning can be filtered as desired using
1275 the warning framework, e.g. silenced completely, turned into an
1276 exception, logged, etc.
1277
1278 Note that compare operators other than equal and unequal will still
1279 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001280
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001281- Fix segfault when doing string formatting on subclasses of long.
1282
1283- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1284 with new-style classes.
1285
1286- Fix bug related to __len__ functions returning negative values with
1287 classic classes.
1288
1289- Patch #1538606, Fix __index__() clipping. There were some problems
1290 discovered with the API and how integers that didn't fit into Py_ssize_t
1291 were handled. This patch attempts to provide enough alternatives
1292 to effectively use __index__.
1293
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001294- Bug #1536021: __hash__ may now return long int; the final hash
1295 value is obtained by invoking hash on the long int.
1296
Thomas Hellerab1049c2006-08-08 17:37:00 +00001297- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1298
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001299- Bug #1535165: fixed a segfault in input() and raw_input() when
1300 sys.stdin is closed.
1301
Thomas Heller74d36f02006-08-04 18:17:40 +00001302- On Windows, the PyErr_Warn function is now exported from
1303 the Python dll again.
1304
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001305- Bug #1191458: tracing over for loops now produces a line event
1306 on each iteration. Fixing this problem required changing the .pyc
1307 magic number. This means that .pyc files generated before 2.5c1
1308 will be regenerated.
1309
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001310- Bug #1333982: string/number constants were inappropriately stored
1311 in the byte code and co_consts even if they were not used, ie
1312 immediately popped off the stack.
1313
Georg Brandle9462c72006-08-04 18:03:37 +00001314- Fixed a reference-counting problem in property().

1318-------
1319
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001320- Fix a bug in the ``compiler`` package that caused invalid code to be
1321 generated for generator expressions.
1322
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001323- The distutils version has been changed to 2.5.0. The change to
1324 keep it programmatically in sync with the Python version running
1325 the code (introduced in 2.5b3) has been reverted. It will continue
1326 to be maintained manually as static string literal.
1327
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001328- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001329 and this cannot be converted to the required C type, an exception is
1330 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001331 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001332
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001333- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001334 an exception.
1335
Tim Petersc10c9d02006-09-05 02:18:09 +00001336- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001337 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001338 workarounds for clocks with low resolution, to stop the code yielding
1339 duplicate UUIDs.
1340
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001341- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1342 before raising SystemExit, allowing IDLE to honor quit() and exit().
1343
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001344- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1345
Georg Brandl7a1af772006-08-14 21:55:28 +00001346- Patch #1536071: trace.py should now find the full module name of a
1347 file correctly even on Windows.
1348
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001349- logging's atexit hook now runs even if the rest of the module has
1350 already been cleaned up.
1351
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001352- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001353
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001354- Bug #1531405, format_exception no longer raises an exception if
1355 str(exception) raised an exception.
1356
Neil Schemenauer06ded092006-08-04 16:20:30 +00001357- Fix a bug in the ``compiler`` package that caused invalid code to be
1358 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001366- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1367 raises the correct exceptions.
1368
Thomas Heller1ce433e2006-08-14 16:20:04 +00001369- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1370 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1371
Thomas Heller86720042006-08-14 11:17:48 +00001372- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1373 uses the _as_parameter_ attribute when objects are passed to foreign
1374 function calls. The ctypes version number was changed to 1.0.1.
1375
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001376- Bug #1530559, struct.pack raises TypeError where it used to convert.
1377 Passing float arguments to struct.pack when integers are expected
1378 now triggers a DeprecationWarning.

1430
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001431- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001432 returned a long (see PEP 353).
1433
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001434- Bug #1515471: string.replace() accepts character buffers again.
1435
Neal Norwitz07aadb12006-07-30 06:55:48 +00001436- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1437 This provides the proper warning for struct.pack().
1438 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1439
Neal Norwitz0d62a062006-07-30 06:53:31 +00001440- Patch #1531113: Fix augmented assignment with yield expressions.
1441 Also fix a SystemError when trying to assign to yield expressions.
1442
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001443- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1444 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1445 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1446 excessive filesystem operations during imports.
1447
Tim Petersbc24eee2006-07-27 01:14:53 +00001448- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1449 operations on signed longs that are formally undefined by C.
1450 Unfortunately, at least one compiler now cares about that, so complicated
1451 the code to make that compiler happy again.

Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001453- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1454
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001455- Patch #1232023: Stop including current directory in search
1456 path on Windows.
1457
Neal Norwitze1fdb322006-07-21 05:32:28 +00001458- Fix some potential crashes found with failmalloc.

1461
Neal Norwitz84be93b2006-07-16 01:50:38 +00001462- Bug #1512814, Fix incorrect lineno's when code within a function
1463 had more than 255 blank lines.
1464
Georg Brandl9dceedb2006-07-12 15:31:17 +00001465- Patch #1521179: Python now accepts the standard options ``--help`` and
1466 ``--version`` as well as ``/?`` on Windows.
1467
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001468- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001469 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001470 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001471
Tim Peters112aad32006-07-19 00:03:19 +00001472- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001473 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001474 new ``sys._current_frames()`` returns a dictionary with one entry,
1475 mapping the faux "thread id" 0 to the current frame.
1476
Ronald Oussoren3075e162006-07-25 20:28:55 +00001477- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

1481-------
1482
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001483- Correction of patch #1455898: In the mbcs decoder, set final=False
1484 for stream decoder, but final=True for the decode function.
1485
Georg Brandl07fec3a2006-08-01 18:49:24 +00001486- os.urandom no longer masks unrelated exceptions like SystemExit or
1487 KeyboardInterrupt.
1488
Tim Peters4643c2f2006-08-10 22:45:34 +00001489- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001490 shutil.copytree on Windows
1491
Georg Brandle34ac7c2006-07-30 11:07:23 +00001492- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1493 refers to file descriptors, not file objects.
1494
Tim Petersc10c9d02006-09-05 02:18:09 +00001495- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001496 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001497 #1513611, and probably others.
1498
Georg Brandledd9b0d2006-07-29 09:33:26 +00001499- Bug #1441397: The compiler module now recognizes module and function
1500 docstrings correctly as it did in Python 2.4.
1501
Tim Peters6f681472006-07-27 23:44:37 +00001502- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1503 lost that tests are sorted by name before being run. This rarely
1504 matters for well-written tests, but can create baffling symptoms if
1505 side effects from one test to the next affect outcomes. ``DocTestFinder``
1506 has been changed to sort the list of tests it returns.
1507
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001508- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001509 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001510
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001511- Bug #978833: Really close underlying socket in _socketobject.close.
1512
Georg Brandl8c036cc2006-08-20 13:15:39 +00001513- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1514 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001515
Georg Brandlcf0c1722006-07-26 07:23:32 +00001516- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1517 to recursive calls and call it with the failing package name.
1518
Martin v. Löwis0b483032006-07-25 09:53:12 +00001519- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1520
Georg Brandlc13c34c2006-07-24 14:09:56 +00001521- Patch #1515343: Fix printing of deprecated string exceptions with a
1522 value in the traceback module.
1523
Greg Ward48fae7a2006-07-23 16:05:51 +00001524- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1525
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001526- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1527
Brett Cannoncaebe222006-07-18 04:41:36 +00001528- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1529 argument tuple. For arguments where zero is illegal, the value is forced to
1530 the minimum value that is correct. This is to support an undocumented but
1531 common way people used to fill in inconsequential information in the time
1532 tuple pre-2.4.
1533
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001534- Patch #1220874: Update the binhex module for Mach-O.
1535
Barry Warsawb110bad2006-07-21 14:51:07 +00001536- The email package has improved RFC 2231 support, specifically for
1537 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1538 (name*0=<blah>) parameter continuations. This may change the types of
1539 values returned from email.message.Message.get_param() and friends.
1540 Specifically in some cases where non-encoded continuations were used,
1541 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1542 will just return the string (since non-encoded continuations don't have
1543 charset and language parts).
1544
1545 Also, whereas % values were decoded in all parameter continuations, they are
1546 now only decoded in encoded parameter parts.
1547
Ronald Oussoren3075e162006-07-25 20:28:55 +00001548- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1549
1550- Bug #1517996: IDLE now longer shows the default Tk menu when a
1551 path browser, class browser or debugger is the frontmost window on MacOS X
1552
Barry Warsaw00decd72006-07-27 23:43:15 +00001553- Patch #1520294: Support for getset and member descriptors in types.py,
1554 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1555 of an object against these built-in types and more importantly, for getting
1556 their docstrings printed in the interactive interpreter's help() function.

1560-----------------
1561
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001562- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1563 a socket operation on a socket with a timeout, the exception will be
1564 caught correctly. Previously, the exception was not caught.
1565
Thomas Heller1393d6a2006-07-28 21:43:20 +00001566- Patch #1529514: The _ctypes extension is now compiled on more
1567 openbsd target platforms.
1568
Tim Peters9cab5932006-07-28 00:30:00 +00001569- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1570 a memory leak, affecting pickles and deep copies.
1571
Tim Petersbc24eee2006-07-27 01:14:53 +00001572- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001573 Paul Eggert.
1574

1576
Thomas Hellerce049a02006-07-14 17:51:14 +00001577- Patch #1521817: Index range checking on ctypes arrays containing
1578 exactly one element enabled again. This allows iterating over these
1579 arrays, without the need to check the array size before.
1580
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001581- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001582 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001583 /dev/null in certain cases; this is now fixed.
1584
Thomas Heller47d7a062006-07-12 08:43:47 +00001585- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1586 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001587
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001588- Because of a misspelled preprocessor symbol, ctypes was always
1589 compiled without thread support; this is now fixed.
1590
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001591- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1592 methods now allow their database parameter to be None as the
1593 sleepycat API allows.
1594
Matt Flemingec926502006-07-28 11:27:27 +00001595- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1596 bluetooth API compared with Linux and FreeBSD.
1597
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001598Tests
1599-----
1600
1601- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1602 how long the test file should take to play. Now accepts taking 2.93 secs
1603 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1604
Georg Brandl4793aa32006-07-28 18:31:39 +00001605- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1606 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1607 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001614Mac
1615---
1616
1617- PythonLauncher now works correctly when the path to the script contains
1618 characters that are treated specially by the shell (such as quotes).
1619
1620- Bug #1527397: PythonLauncher now launches scripts with the working directory
1621 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001622 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001623 expect.

1632-----------------
1633
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001634- Bug #1441486: The literal representation of -(sys.maxint - 1)
1635 again evaluates to a int object, not a long.
1636
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001637- Bug #1501934: The scope of global variables that are locally assigned
1638 using augmented assignment is now correctly determined.
1639
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001640- Bug #927248: Recursive method-wrapper objects can now safely
1641 be released.
1642
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001643- Bug #1417699: Reject locale-specific decimal point in float()
1644 and atof().
1645
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001646- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1647 omit a default "error" argument for NULL pointer. This allows
1648 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001649
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001650- Bug #1519018: 'as' is now validated properly in import statements.
1651
Neal Norwitz28746ab2006-07-09 22:14:42 +00001652- On 64 bit systems, int literals that use less than 64 bits are
1653 now ints rather than longs.
1654
Neal Norwitzed657552006-07-10 00:04:44 +00001655- Bug #1512814, Fix incorrect lineno's when code at module scope
1656 started after line 256.
1657
Tim Peters32a83612006-07-10 21:08:24 +00001658- New function ``sys._current_frames()`` returns a dict mapping thread
1659 id to topmost thread stack frame. This is for expert use, and is
1660 especially useful for debugging application deadlocks. The functionality
1661 was previously available in Fazal Majid's ``threadframe`` extension
1662 module, but it wasn't possible to do this in a wholly threadsafe way from
1663 an extension.

1672
Tim Peters32a83612006-07-10 21:08:24 +00001673- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001674 environment variable to be set in order to the SDK environment
1675 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +00001679- warnings.py now ignores ImportWarning by default
1680
Thomas Woutersadd19112006-07-05 11:03:49 +00001681- string.Template() now correctly handles tuple-values. Previously,
1682 multi-value tuples would raise an exception and single-value tuples would
1683 be treated as the value they contain, instead.
1684
Martin v. Löwisede77f52006-07-03 13:01:35 +00001685- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1687
Martin v. Löwis45482392006-07-03 12:28:58 +00001688- Bug #1267547: Put proper recursive setup.py call into the
1689 spec file generated by bdist_rpm.
1690
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001691- Bug #1514693: Update turtle's heading when switching between
1692 degrees and radians.
1693
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001694- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001695 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001696
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001697- Bug #1514703: Only setup canvas window in turtle when the canvas
1698 is created.
1699
Martin v. Löwis7596e832006-07-01 15:33:37 +00001700- Bug #1513223: .close() of a _socketobj now releases the underlying
1701 socket again, which then gets closed as it becomes unreferenced.
1702
Fred Drake10497c82006-06-29 02:57:48 +00001703- Bug #1504333: Make sgmllib support angle brackets in quoted
1704 attribute values.

1706- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1707 sgmllib ('[' and ']' were not accepted).
1708
Georg Brandl1be63af2006-06-28 20:23:25 +00001709- Fix a bug in the turtle module's end_fill function.
1710
Brett Cannon53ab5b72006-06-22 16:49:14 +00001711- Bug #1510580: The 'warnings' module improperly required that a Warning
1712 category be either a types.ClassType and a subclass of Warning. The proper
1713 check is just that it is a subclass with Warning as the documentation states.
1714
Georg Brandlad29e632006-06-21 17:45:17 +00001715- The compiler module now correctly compiles the new try-except-finally
1716 statement (bug #1509132).
1717
Neal Norwitz60373cd2006-06-22 06:30:50 +00001718- The wsgiref package is now installed properly on Unix.
1719
Vinay Sajip28e57612006-07-01 10:45:20 +00001720- A bug was fixed in logging.config.fileConfig() which caused a crash on
1721 shutdown when fileConfig() was called multiple times.
1722
Gerhard Häring762fbd32006-07-02 17:48:30 +00001723- The sqlite3 module did cut off data from the SQLite database at the first
1724 null character before sending it to a custom converter. This has been fixed
1725 now.

Tim Peters112aad32006-07-19 00:03:19 +00001730- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1731 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1732 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001733
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001734- Assigning None to pointer type fields in ctypes structures possible
1735 overwrote the wrong fields, this is fixed now.
1736
1737- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1738 on non-Windows platforms.
1739
1740- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1741 integer or long, without range checking.
1742
1743- Patch #1517790: It is now possible to use custom objects in the ctypes
1744 foreign function argtypes sequence as long as they provide a from_param
1745 method, no longer is it required that the object is a ctypes type.
1746
1747- The '_ctypes' extension module now works when Python is configured
1748 with the --without-threads option.
1749
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001750- Bug #1513646: os.access on Windows now correctly determines write
1751 access, again.
1752
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001753- Bug #1512695: cPickle.loads could crash if it was interrupted with
1754 a KeyboardInterrupt.
1755
Neal Norwitza12aa882006-07-06 06:45:08 +00001756- Bug #1296433: parsing XML with a non-default encoding and
1757 a CharacterDataHandler could crash the interpreter in pyexpat.
1758
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001759- Patch #1516912: improve Modules support for OpenVMS.

1762-----
1763
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001764- Automate Windows build process for the Win64 SSL module.
1765
Tim Peters32a83612006-07-10 21:08:24 +00001766- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001767 Previously, the slight difference could cause compilation errors of the
1768 'zlib' module on systems with more than one version of zlib.
1769
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001770- The MSI compileall step was fixed to also support a TARGETDIR
1771 with spaces in it.
1772
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001773- Bug #1517388: sqlite3.dll is now installed on Windows independent
1774 of Tcl/Tk.
1775
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001776- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001777 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001779Tests
1780-----
1781
1782- Call os.waitpid() at the end of tests that spawn child processes in order
1783 to minimize resources (zombies).
1784
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001785Documentation
1786-------------
1787
Nick Coghlan2d792252006-07-06 13:47:18 +00001788- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1789 documentation for the warnings module.
1790
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001791- Patch #1509163: MS Toolkit Compiler no longer available.
1792
Neal Norwitz56640df2006-07-10 02:36:41 +00001793- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +00001796What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001797================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001798
Anthony Baxterd1136802006-06-19 12:04:15 +00001799*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001800
1801Core and builtins
1802-----------------
1803
Georg Brandla56b9152006-06-19 06:35:54 +00001804- Patch #1507676: Error messages returned by invalid abstract object operations
1805 (such as iterating over an integer) have been improved and now include the
1806 type of the offending object to help with debugging.
1807
Brett Cannonea3912b2006-06-13 21:46:41 +00001808- Bug #992017: A classic class that defined a __coerce__() method that returned
1809 its arguments swapped would infinitely recurse and segfault the interpreter.
1810
Neal Norwitz909eb122006-06-12 02:13:21 +00001811- Fix the socket tests so they can be run concurrently.
1812
Neal Norwitzb9845e72006-06-12 02:11:18 +00001813- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001814 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001815
Brett Cannon22565aa2006-06-09 22:31:23 +00001816- Bug #532646: object.__call__() will continue looking for the __call__
1817 attribute on objects until one without one is found. This leads to recursion
1818 when you take a class and set its __call__ attribute to an instance of the
1819 class. Originally fixed for classic classes, but this fix is for new-style.
1820 Removes the infinite_rec_3 crasher.
1821
Georg Brandl24250812006-06-09 18:45:48 +00001822- The string and unicode methods startswith() and endswith() now accept
1823 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1824
Brett Cannonde3b0522006-06-08 17:00:45 +00001825- Buffer objects, at the C level, never used the char buffer
1826 implementation even when the char buffer for the wrapped object was
1827 explicitly requested (originally returned the read or write buffer).
1828 Now a TypeError is raised if the char buffer is not present but is
1829 requested.
1830
Georg Brandlddbaa662006-06-04 21:56:52 +00001831- Patch #1346214: Statements like "if 0: suite" are now again optimized
1832 away like they were in Python 2.4.
1833
Georg Brandlb7c8f542006-05-27 12:30:25 +00001834- Builtin exceptions are now full-blown new-style classes instead of
1835 instances pretending to be classes, which speeds up exception handling
1836 by about 80% in comparison to 2.5a2.
1837
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001838- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1839 Unicode 4.1.
1840
Georg Brandlf4ef1162006-05-26 18:03:31 +00001841- Patch #921466: sys.path_importer_cache is now used to cache valid and
1842 invalid file paths for the built-in import machinery which leads to
1843 fewer open calls on startup.
1844
Tim Peters696cf432006-05-24 21:10:40 +00001845- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1846 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1847 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1848 the number of input digits (it was and remains linear-time for bases
1849 2, 4, 8, 16 and 32).
1850
Tim Petersb713ec22006-05-23 18:45:30 +00001851- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1852 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1853 an integer close to ``sys.maxint``. This was repaired by patch
1854 #1335972, which also gives a nice speedup.
1855
Richard Jonescebbefc2006-05-23 18:28:17 +00001856- Patch #1337051: reduced size of frame objects.
1857
1858- PyErr_NewException now accepts a tuple of base classes as its
1859 "base" parameter.
1860
Richard Jones7c88dcc2006-05-23 10:37:38 +00001861- Patch #876206: function call speedup by retaining allocated frame
1862 objects.
1863
Georg Brandl7b90e162006-05-18 07:01:27 +00001864- Bug #1462152: file() now checks more thoroughly for invalid mode
1865 strings and removes a possible "U" before passing the mode to the
1866 C library function.
1867
Neal Norwitz1004a532006-05-15 07:17:23 +00001868- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1869
Neal Norwitz373f0a72006-05-15 07:04:36 +00001870- Bug #1487966: Fix SystemError with conditional expression in assignment
1871
Martin v. Löwis879768d2006-05-11 13:28:43 +00001872- WindowsError now has two error code attributes: errno, which carries
1873 the error values from errno.h, and winerror, which carries the error
1874 values from winerror.h. Previous versions put the winerror.h values
1875 (from GetLastError()) into the errno attribute.
1876
Martin v. Löwis77736712006-05-04 05:51:03 +00001877- Patch #1475845: Raise IndentationError for unexpected indent.
1878
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001879- Patch #1479181: split open() and file() from being aliases for each other.
1880
Tim Peters44bd9862006-06-01 13:49:23 +00001881- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1882 methods were always silently ignored by dictionaries when comparing keys.
1883 They are now passed through (except when using the C API function
1884 ``PyDict_GetItem()``, whose semantics did not change).
1885
1886- Bug #1456209: In some obscure cases it was possible for a class with a
1887 custom ``__eq__()`` method to confuse dict internals when class instances
1888 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1889 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001891Extension Modules
1892-----------------
1893
Trent Mick960a3f82006-06-28 20:30:41 +00001894- Bug #1295808: expat symbols should be namespaced in pyexpat
1895
1896- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1897
Brett Cannon6ee7d012006-06-08 16:23:04 +00001898- Change binascii.hexlify to accept a read-only buffer instead of only a char
1899 buffer and actually follow its documentation.
1900
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001901- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1902
Nick Coghlanc649ec52006-05-29 12:43:05 +00001903- Patch #1478788 (modified version): The functional extension module has
1904 been renamed to _functools and a functools Python wrapper module added.
1905 This provides a home for additional function related utilities that are
1906 not specifically about functional programming. See PEP 309.
1907
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001908- Patch #1493701: performance enhancements for struct module.
1909
Georg Brandl378d5922006-05-17 14:26:50 +00001910- Patch #1490224: time.altzone is now set correctly on Cygwin.
1911
Georg Brandl8d3342b2006-05-16 07:38:27 +00001912- Patch #1435422: zlib's compress and decompress objects now have a
1913 copy() method.
1914
Andrew MacIntyre92913322006-06-13 15:04:24 +00001915- Patch #1454481: thread stack size is now tunable at runtime for thread
1916 enabled builds on Windows and systems with Posix threads support.
1917
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001918- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1919 (up to the system limit of 32K characters).
1920
1921- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1922 As a result, these functions now raise WindowsError instead of OSError.
1923
Tim Peters7a822da2006-05-25 21:50:17 +00001924- ``time.clock()`` on Win64 should use the high-performance Windows
1925 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1926 Windows platforms).
1927
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001928- Calling Tk_Init twice is refused if the first call failed as that
1929 may deadlock.
1930
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001931- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1932 accept it without potentially using an uninitialized pointer.
1933
1934- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1935 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1936 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001937
Gregory P. Smith372b5832006-06-05 18:48:21 +00001938- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001939 [pybsddb project SF patch number 1466734]
1940
Gregory P. Smith372b5832006-06-05 18:48:21 +00001941- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1942 parameter is supplied. [SF pybsddb bug #1477863]
1943
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001944- bsddb: the __len__ method of a DB object has been fixed to return correct
1945 results. It could previously incorrectly return 0 in some cases.
1946 Fixes SF bug 1493322 (pybsddb bug 1184012).
1947
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001948- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1949 aborts the db transaction safely when a modifier callback fails.
1950 Fixes SF python patch/bug #1408584.
1951
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001952- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001953 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001954 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1955 database calls that would previously deadlock. [SF python bug #775414]
1956
Vinay Sajip28e57612006-07-01 10:45:20 +00001957- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001958
Walter Dörwald4994d952006-06-19 08:07:50 +00001959- Patch #1506645: add Python wrappers for the curses functions
1960 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001961

1963-------
1964
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001965- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1966 functions.
1967
Martin v. Löwis3798da02006-06-17 18:44:27 +00001968- Patch #812986: Update turtle output even if not tracing.
1969
Vinay Sajip28e57612006-07-01 10:45:20 +00001970- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001971 Tkinter.BaseWidget.
1972
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001973- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1974
Martin v. Löwis337487e2006-06-17 09:15:14 +00001975- Patch #763580: Add name and value arguments to Tkinter variable
1976 classes.
1977
Georg Brandl83cc0d02006-06-14 08:50:03 +00001978- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1979 mime.types file for determining MIME types.
1980
Georg Brandl2605ca82006-06-14 06:08:31 +00001981- Bug #1339007: Shelf objects now don't raise an exception in their
1982 __del__ method when initialization failed.
1983
Martin v. Löwisd8251432006-06-14 05:21:04 +00001984- Patch #1455898: The MBCS codec now supports the incremental mode for
1985 double-byte encodings.
1986
Tim Peters43898b42006-06-14 04:09:25 +00001987- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1988 guarantee that adjacent triples in the return list always describe
1989 non-adjacent blocks. Previously, a pair of matching blocks could end
1990 up being described by multiple adjacent triples that formed a partition
1991 of the matching pair.
1992
Greg Ward0e0c9f42006-06-11 16:24:11 +00001993- Bug #1498146: fix optparse to handle Unicode strings in option help,
1994 description, and epilog.
1995
Greg Wardd1c797e2006-06-11 14:42:41 +00001996- Bug #1366250: minor optparse documentation error.
1997
Greg Ward7f547402006-06-11 00:40:49 +00001998- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1999 clarify docs.
2000
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002001- The wsgiref package has been added to the standard library.
2002
Nick Coghlan676725d2006-06-08 13:54:49 +00002003- The functions update_wrapper() and wraps() have been added to the functools
2004 module. These make it easier to copy relevant metadata from the original
2005 function when writing wrapper functions.
2006
Tim Petersd6a9eef2006-06-05 01:48:21 +00002007- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2008 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002009
Martin v. Löwis3f767792006-06-04 19:36:28 +00002010- Patch #1359618: Speed up charmap encoder by using a trie structure
2011 for lookup.
2012
Tim Petersd609b1a2006-06-02 23:22:51 +00002013- The functions in the ``pprint`` module now sort dictionaries by key
2014 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2015 if and only if its display required more than one line, although that
2016 wasn't documented. The new behavior increases predictability; e.g.,
2017 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2018
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002019- Patch #1497027: try HTTP digest auth before basic auth in urllib2

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002089What's New in Python 2.5 alpha 2?
2090=================================
2091
2092*Release date: 27-APR-2006*
2093
2094Core and builtins
2095-----------------
2096
Thomas Heller1b046642006-04-18 18:51:06 +00002097- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2098 by converting these apis from macros into exported functions again:
2099
2100 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2101 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2102 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2103 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2104 PyRun_String Py_CompileString
2105
Martin v. Löwis45294a92006-04-18 06:24:08 +00002106- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2107
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002108- All uses of PyStructSequence_InitType have been changed to initialize
2109 the type objects only once, even if the interpreter is initialized
2110 multiple times.
2111
Neal Norwitz61546162006-04-14 05:20:28 +00002112- Bug #1454485, array.array('u') could crash the interpreter. This was
2113 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2114 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2115
2116- Py_UNICODE is unsigned. It was always documented as unsigned, but
2117 due to a bug had a signed value in previous versions.
2118
Tim Peters3a5e8b12006-04-11 01:44:07 +00002119- Patch #837242: ``id()`` of any Python object always gives a positive
2120 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2121 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002122 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002123 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002124
Tim Peters3a5e8b12006-04-11 01:44:07 +00002125 def __hash__(self):
2126 return id(self) # WRONG
2127
2128 because a hash result must be a (short) Python int but it was always
2129 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002130 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002131 was always usable as a hash value before this patch. That's no longer
2132 necessarily so.
2133
2134- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002135 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002136 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002137 #1454844)
2138
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002139- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2140 involving generators that have paused outside of any ``try`` or ``with``
2141 blocks. (In 2.5a1, a paused generator that was part of a reference
2142 cycle could not be garbage collected, regardless of whether it was
2143 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002144
Anthony Baxter51bcb682006-04-05 14:51:42 +00002145Extension Modules
2146-----------------
2147
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002148- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2149 is a macro.
2150
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002151- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2152 fails with an error condition.
2153
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002154- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2155
2156- Bug #1117761: bsddb.*open() no longer raises an exception when using
2157 the cachesize parameter.
2158
2159- Bug #1149413: bsddb.*open() no longer raises an exception when using
2160 a temporary db (file=None) with the 'n' flag to truncate on open.
2161
2162- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2163 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002164
Armin Rigoa9017c32006-04-19 11:50:27 +00002165- Patch #1062014: AF_UNIX sockets under Linux have a special
2166 abstract namespace that is now fully supported.
2167

2169-------
2170
Peter Astrand7d1d4362006-07-14 14:04:45 +00002171- Bug #1223937: subprocess.CalledProcessError reports the exit status
2172 of the process using the returncode attribute, instead of
2173 abusing errno.
2174
Tim Peters711bf302006-04-25 03:31:36 +00002175- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2176 a doctest to be skipped (the code is not run, and the expected output
2177 or exception is ignored).
2178
Nick Coghlanda2268f2006-04-24 04:37:15 +00002179- Fixed contextlib.nested to cope with exceptions being raised and
2180 caught inside exit handlers.
2181
Greg Wardab05edc2006-04-23 03:47:58 +00002182- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2183 hex, octal, or binary; add ``append_const`` action; keep going if
2184 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2185 added ``epilog`` for better help generation).
2186
Tim Peters21fbd572006-04-21 21:18:10 +00002187- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2188 called from a thread spawned as a side effect of importing a module.
2189
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002190- The pydoc module now supports documenting packages contained in
2191 .zip or .egg files.
2192
2193- The pkgutil module now has several new utility functions, such
2194 as ``walk_packages()`` to support working with packages that are either
2195 in the filesystem or zip files.
2196
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002197- The mailbox module can now modify and delete messages from
2198 mailboxes, in addition to simply reading them. Thanks to Gregory
2199 K. Johnson for writing the code, and to the 2005 Google Summer of
2200 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002201
Tim Petersc7605f22006-04-17 21:12:33 +00002202- The ``__del__`` method of class ``local`` in module ``_threading_local``
2203 returned before accomplishing any of its intended cleanup.
2204
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002205- Patch #790710: Add breakpoint command lists in pdb.
2206
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002207- Patch #1063914: Add Tkinter.Misc.clipboard_get().
2208
Martin v. Löwis4b501e62006-04-15 08:41:11 +00002209- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
2210
Anthony Baxtere29002c2006-04-12 12:07:31 +00002211- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2212 Windows. Bug #1469163.
2213
Phillip J. Eby47032112006-04-11 01:07:43 +00002214- The warnings, linecache, inspect, traceback, site, and doctest modules
2215 were updated to work correctly with modules imported from zipfiles or
2216 via other PEP 302 __loader__ objects.
2217
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002218- Patch #1467770: Reduce usage of subprocess._active to processes which
2219 the application hasn't waited on.
2220
Martin v. Löwisb04dee92006-04-10 08:34:21 +00002221- Patch #1462222: Fix Tix.Grid.
2222
Neal Norwitza31bf182006-04-09 03:35:43 +00002223- Fix exception when doing glob.glob('anything*/')
2224
Skip Montanaro262fb922006-04-21 02:31:07 +00002225- The pstats.Stats class accepts an optional stream keyword argument to
2226 direct output to an alternate file-like object.
2227
Anthony Baxter51bcb682006-04-05 14:51:42 +00002228Build
2229-----
2230
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002231- The Makefile now has a reindent target, which runs reindent.py on
2232 the library.
2233
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002234- Patch #1470875: Building Python with MS Free Compiler
2235
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002236- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002237
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002238- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2239 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002240 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002241 CXX from --with-cxx-main, see description in README.
2242
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002243- Patch #1429775: Link extension modules with the shared libpython.
2244
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002245- Fixed a libffi build problem on MIPS systems.
2246
Tim Peters8931ff12006-05-13 23:28:20 +00002247- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2248 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2249 and "%zu" for unsigned integers of type ``size_t``.
2250
Anthony Baxter51bcb682006-04-05 14:51:42 +00002251Tests
2252-----
2253
Nick Coghlanda2268f2006-04-24 04:37:15 +00002254- test_contextlib now checks contextlib.nested can cope with exceptions
2255 being raised and caught inside exit handlers.
2256
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002257- test_cmd_line now checks operation of the -m and -c command switches
2258
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002259- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2260 it separately and by hand. It also wasn't cleaning up its changes to
2261 the current Decimal context.
2262
Thomas Woutersabd08882006-04-26 15:53:30 +00002263- regrtest.py now has a -M option to run tests that test the new limits of
2264 containers, on 64-bit architectures. Running these tests is only sensible
2265 on 64-bit machines with more than two gigabytes of memory. The argument
2266 passed is the maximum amount of memory for the tests to use.

2275-------------
2276
Tim Petersb06d28c2006-05-12 01:57:59 +00002277- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2278
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002279- PEP 343: Added Context Types section to the library reference
2280 and attempted to bring other PEP 343 related documentation into
2281 line with the implementation and/or python-dev discussions.
2282
Tim Peters8dc73d22006-04-24 02:03:16 +00002283- Bug #1337990: clarified that ``doctest`` does not support examples
2284 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002287What's New in Python 2.5 alpha 1?
2288=================================
2289
Anthony Baxterebed3f62006-04-03 15:03:44 +00002290*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002291
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002292Core and builtins
2293-----------------
2294
Nick Coghlan43832302006-04-23 17:04:07 +00002295- PEP 338: -m command line switch now delegates to runpy.run_module
2296 allowing it to support modules in packages and zipfiles
2297
Martin v. Löwisc661b882006-04-20 04:54:23 +00002298- On Windows, .DLL is not an accepted file name extension for
2299 extension modules anymore; extensions are only found if they
2300 end in .PYD.
2301
Martin v. Löwisea62d252006-04-03 10:56:49 +00002302- Bug #1421664: sys.stderr.encoding is now set to the same value as
2303 sys.stdout.encoding.
2304
Neal Norwitz92e212f2006-04-03 04:48:37 +00002305- __import__ accepts keyword arguments.
2306
Georg Brandlccadf842006-03-31 18:54:53 +00002307- Patch #1460496: round() now accepts keyword arguments.
2308
Anthony Baxter262c00a2006-03-30 10:53:17 +00002309- Fixed bug #1459029 - unicode reprs were double-escaped.
2310
Hye-Shik Changd478f342006-03-23 12:32:36 +00002311- Patch #1396919: The system scope threads are reenabled on FreeBSD
2312 5.4 and later versions.
2313
Neal Norwitze98ccf62006-03-23 05:39:47 +00002314- Bug #1115379: Compiling a Unicode string with an encoding declaration
2315 now gives a SyntaxError.
2316
Georg Brandlabd1ff82006-03-18 07:59:59 +00002317- Previously, Python code had no easy way to access the contents of a
2318 cell object. Now, a ``cell_contents`` attribute has been added
2319 (closes patch #1170323).
2320
Tim Peterscf79aac2006-03-16 01:14:46 +00002321- Patch #1123430: Python's small-object allocator now returns an arena to
2322 the system ``free()`` when all memory within an arena becomes unused
2323 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2324 freed. Some applications will see a drop in virtual memory size now,
2325 especially long-running applications that, from time to time, temporarily
2326 use a large number of small objects. Note that when Python returns an
2327 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002328 platform C library will in turn return that memory to the operating system.
2329 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002330 appears to be effective at least on Microsoft C and gcc-based systems.
2331 Thanks to Evan Jones for hard work and patience.

Georg Brandl533ff6f2006-03-08 18:09:27 +00002333- Patch #1434038: property() now uses the getter's docstring if there is
2334 no "doc" argument given. This makes it possible to legitimately use
2335 property() as a decorator to produce a read-only property.
2336
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002337- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2338 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2339 of requiring an int or long in slicing and a few other contexts, enabling
2340 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2341
Neal Norwitz995acdf2006-03-07 05:01:00 +00002342- Fixed various bugs reported by Coverity's Prevent tool.
2343
Brett Cannonbf364092006-03-01 04:25:17 +00002344- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2345 new exception base class, BaseException, which has a new message attribute.
2346 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2347 Raising a string exception now raises a DeprecationWarning.
2348
Thomas Woutersfb609f42006-02-28 16:37:25 +00002349- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2350 explicitly relative, using 'from .module import name' to mean 'from the same
2351 package as this module is in. Imports without dots still default to the
2352 old relative-then-absolute, unless 'from __future__ import
2353 absolute_import' is used.
2354
Brett Cannona7446e32006-02-27 23:39:10 +00002355- Properly check if 'warnings' raises an exception (usually when a filter set
2356 to "error" is triggered) when raising a warning for raising string
2357 exceptions.
2358
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002359- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002360 The name was removed from Include/code.h.
2361
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002362- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002363
Guido van Rossum1968ad32006-02-25 22:38:04 +00002364- Patch 1433928:
2365 - The copy module now "copies" function objects (as atomic objects).
2366 - dict.__getitem__ now looks for a __missing__ hook before raising
2367 KeyError.
2368
Tim Peters84ef21c2006-02-28 20:39:06 +00002369- PEP 343: with statement implemented. Needs ``from __future__ import
2370 with_statement``. Use of 'with' as a variable will generate a warning.
2371 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002372 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002373 The following objects have __context__ methods:
2374 - The built-in file type.
2375 - The thread.LockType type.
2376 - The following types defined by the threading module:
2377 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2378 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002379
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002380- Fix the encodings package codec search function to only search
2381 inside its own package. Fixes problem reported in patch #1433198.
2382
2383 Note: Codec packages should implement and register their own
2384 codec search function. PEP 100 has the details.
2385
Tim Peters9ea89d22006-06-04 03:26:02 +00002386- PEP 353: Using ``Py_ssize_t`` as the index type.
2387
2388- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2389 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2390 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2391 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2392 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002393
Neal Norwitzfc76d632006-01-10 06:03:13 +00002394- Patch #1400181, fix unicode string formatting to not use the locale.
2395 This is how string objects work. u'%f' could use , instead of .
2396 for the decimal point. Now both strings and unicode always use periods.
2397
Neal Norwitz671b9e32006-01-09 07:07:12 +00002398- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2399 configure would break checking curses.h.
2400
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002401- Bug #959576: The pwd module is now builtin. This allows Python to be
2402 built on UNIX platforms without $HOME set.
2403
Neal Norwitzc10978f2005-12-19 06:07:16 +00002404- Bug #1072182, fix some potential problems if characters are signed.
2405
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002406- Bug #889500, fix line number on SyntaxWarning for global declarations.
2407
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002408- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2409
Neal Norwitze7214a12005-12-18 05:03:17 +00002410- Support for converting hex strings to floats no longer works.
2411 This was not portable. float('0x3') now raises a ValueError.
2412
Barry Warsaw2a38a862005-12-18 01:27:35 +00002413- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002414 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002415 is now displayed in interactive prompt banner.
2416
Georg Brandlfa166682005-12-17 21:45:17 +00002417- Implementation of PEP 341 - Unification of try/except and try/finally.
2418 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002419 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002420
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002421- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2422 now encodes backslash correctly.
2423
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002424- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2425
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002426- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002427 and long longs.
2428
Neal Norwitz67715f02005-11-09 06:59:35 +00002429- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002430 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002431 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002432
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002433- Replaced most Unicode charmap codecs with new ones using the
2434 new Unicode translate string feature in the builtin charmap
2435 codec; the codecs were created from the mapping tables available
2436 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2437 encodings now include a mapping for the Apple logo)
2438
Tim Peterse3547fd2005-12-16 23:13:57 +00002439- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002440
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002441- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002442
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002443- A new AST parser implementation was completed. The abstract
2444 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002445 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002446
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002447- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002448 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2449
Neal Norwitz708e51a2005-10-03 04:48:15 +00002450- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2451
Neal Norwitz11bd1192005-10-03 00:54:56 +00002452- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2453 Provide a warning when a directory is passed on the command line.
2454
Neal Norwitz40d37812005-10-02 01:48:49 +00002455- Fix segfault with invalid coding.
2456
2457- SF bug #772896: unknown encoding results in MemoryError.
2458
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002459- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002460 supported a __len__() method which evaluated to False when the iterator
2461 was empty.
2462
Guido van Rossum630db602005-09-20 18:49:54 +00002463- On 64-bit platforms, when __len__() returns a value that cannot be
2464 represented as a C int, raise OverflowError.
2465
Skip Montanarof8948ca2005-09-19 03:54:46 +00002466- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002467 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002468
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002469- SF bug #893549: parsing keyword arguments was broken with a few format
2470 codes.
2471
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002472- Changes donated by Elemental Security to make it work on AIX 5.3
2473 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2474 bug #105470: test_pwd fails on 64bit system (Opteron).
2475
Guido van Rossum539c6622005-09-14 17:49:54 +00002476- Changes donated by Elemental Security to make it work on HP-UX 11 on
2477 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2478
Georg Brandl4550b8d2005-08-26 06:43:52 +00002479- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002480 (fixes bug #1119418).
2481
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002482- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2483
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002484- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2485 exceptions that cause a function to exit.
2486
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002487- The implementation of set() and frozenset() was revised to use its
2488 own internal data structure. Memory consumption is reduced by 1/3
2489 and there are modest speed-ups as well. The API is unchanged.
2490
Tim Petersde7990b2005-07-17 23:45:23 +00002491- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2492
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002493- SF bug #1229429: PyObject_CallMethod failed to decrement some
2494 reference counts in some error exit cases.
2495
Tim Petersecc6e6a2005-07-10 22:30:55 +00002496- SF bug #1185883: Python's small-object memory allocator took over
2497 a block managed by the platform C library whenever a realloc specified
2498 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002499 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002500 portable way to copy data from the C-managed block into Python's
2501 small-object space without risking a memory fault. Python's small-object
2502 realloc now leaves such blocks under the control of the platform C
2503 realloc.
2504
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002505- SF bug #1232517: An overflow error was not detected properly when
2506 attempting to convert a large float to an int in os.utime().
2507
Raymond Hettinger3296e692005-06-29 23:29:56 +00002508- SF bug #1224347: hex longs now print with lowercase letters just
2509 like their int counterparts.
2510
Michael W. Hudson188d4362005-06-20 16:52:57 +00002511- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2512 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2513 interpreter states; back out that fix and do a better job (see
2514 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2515 for a longer write-up of the problem).
2516
Michael W. Hudsondf888462005-06-03 14:41:55 +00002517- SF patch #1180995: marshal now uses a binary format by default when
2518 serializing floats.
2519
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002520- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2521 the routines that promise to produce IEEE 754 binary representations
2522 of floats now simply copy bytes around.
2523
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002524- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2525 278.
2526
Brett Cannonc3647ac2005-04-26 03:45:26 +00002527- patch #1109424: int, long, float, complex, and unicode now check for the
2528 proper magic slot for type conversions when subclassed. Previously the
2529 magic slot was ignored during conversion. Semantics now match the way
2530 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002531 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002532 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002533 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002534
Barry Warsawc8d907c2005-04-19 23:43:40 +00002535- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2536 NULL, now raise an AttributeError when attempting to set or delete the
2537 attribute. Previously a TypeError was raised, but this was inconsistent
2538 with the equivalent pure-Python implementation.
2539
Michael W. Hudson774479c2005-04-18 08:46:17 +00002540- It is now safe to call PyGILState_Release() before
2541 PyEval_InitThreads() (note that if there is reason to believe there
2542 are multiple threads around you still must call PyEval_InitThreads()
2543 before using the Python API; this fix is for extension modules that
2544 have no way of knowing if Python is multi-threaded yet).
2545
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002546- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2547 disabled caused a crash.
2548
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002549- Bug #1165306: instancemethod_new allowed the creation of a method
2550 with im_class == im_self == NULL, which caused a crash when called.
2551
Tim Petersecc6e6a2005-07-10 22:30:55 +00002552- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002553 fixes the crash seen in bug #1165761
2554
Raymond Hettinger96229b12005-03-11 06:49:40 +00002555- Added two new builtins, any() and all().
2556
Brett Cannon409d8f22005-03-05 06:47:57 +00002557- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002558 (e.g., ``class C(): pass`` is no longer a syntax error).
2559 Patch #1176012 added support to the 'parser' module and 'compiler' package
2560 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002561
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002562- Patch #1115086: Support PY_LONGLONG in structmember.
2563
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002564- Bug #1155938: new style classes did not check that __init__() was
2565 returning None.
2566
Tim Petersecc6e6a2005-07-10 22:30:55 +00002567- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002568 ('\') with a specific error message.
2569
Martin v. Löwisff232d72005-03-03 09:24:38 +00002570- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2571
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002572- Bug #1124295: the __name__ attribute of file objects was
2573 inadvertently made inaccessible in restricted mode.
2574
Tim Petersecc6e6a2005-07-10 22:30:55 +00002575- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002576 an ferror() call.
2577
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002578- min() and max() now support key= arguments with the same meaning as in
2579 list.sort().
2580
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002581- The peephole optimizer now performs simple constant folding in expressions:
2582 (2+3) --> (5).
2583
Raymond Hettingera422c342005-01-11 03:03:27 +00002584- set and frozenset objects can now be marshalled. SF #1098985.
2585
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002586- Bug #1077106: Poor argument checking could cause memory corruption
2587 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002588
Jeremy Hyltonab630502005-02-04 18:44:06 +00002589- The parser did not complain about future statements in illegal
2590 positions. It once again reports a syntax error if a future
2591 statement occurs after anything other than a doc string.
2592
Neil Schemenauercf52c072005-08-12 17:34:58 +00002593- Change the %s format specifier for str objects so that it returns a
2594 unicode instance if the argument is not an instance of basestring and
2595 calling __str__ on the argument returns a unicode instance.
2596
Tim Petersf4e69282006-02-27 17:15:31 +00002597- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2598 current thread state when the auto-GIL-state machinery knows about
2599 it (since the thread state is being deleted, continuing to remember it
2600 can't help, but can hurt if another thread happens to get created with
2601 the same thread id).

Michael W. Hudson8137bea2005-07-27 20:24:40 +00002733- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
2734 the request code argument, which results in more C-like behaviour
2735 for large or negative values.
2736
Tim Petersecc6e6a2005-07-10 22:30:55 +00002737- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2746 available on the platform.
2747

2752
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002753- operator.itemgetter() and operator.attrgetter() now support retrieving

2776
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002777- the cPickle module no longer accepts the deprecated None option in the
2778 args tuple returned by __reduce__().
2779
Raymond Hettingerb2594052004-12-05 09:25:51 +00002780- itertools.islice() now accepts None for the start and step arguments.
2781 This allows islice() to work more readily with slices:
2782 islice(s.start, s.stop, s.step)
2783
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002784- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002793- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2794 been renamed to have only a single underscore prefix. This was done to
2795 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002796
Nick Coghlan43832302006-04-23 17:04:07 +00002797- PEP 338: new module runpy defines a run_module function to support
2798 executing modules which provide access to source code or a code object
2799 via the PEP 302 import mechanisms.
2800
Anthony Baxter93f5b932006-04-03 08:05:07 +00002801- The email module's parsedate_tz function now sets the daylight savings
2802 flag to -1 (unknown) since it can't tell from the date whether it should
2803 be set.
2804
Fred Drakead5177c2006-04-01 22:14:43 +00002805- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
2806 now sport attributes that provide access to the parts of the result.
2807

2809 in attribute values.
2810
Anthony Baxterc51ee692006-04-01 00:57:31 +00002811- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002812 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002813 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002814 module will not be built.
2815
Tim Petersc17976e2006-04-01 00:26:53 +00002816- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2817 aren't officially supported here, and trying to use them will probably
2818 raise an exception some day. But dicts have been allowed, and "mostly
2819 worked", so support for them won't go away without warning.
2820
Georg Brandl338ef7d2006-03-31 18:42:16 +00002821- Bug #1445068: getpass.getpass() can now be given an explicit stream
2822 argument to specify where to write the prompt.
2823
Georg Brandl22ec80b2006-03-31 18:25:44 +00002824- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2839
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002840- email 4.0 package now integrated. This is largely the same as the email 3.0
2841 package that was included in Python 2.3, except that PEP 8 module names are
2842 now used (e.g. mail.message instead of email.Message). The MIME classes
2843 have been moved to a subpackage (e.g. email.mime.text instead of
2844 email.MIMEText). The old names are still supported for now. Several
2845 deprecated Message methods have been removed and lots of bugs have been
2846 fixed. More details can be found in the email package documentation.
2847
Walter Dörwald40108c92006-03-27 08:15:44 +00002848- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2849 (a subclass of tuple) that provides incremental decoders and encoders
2850 (a way to use stateful codecs without the stream API). Python functions
2851 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2852 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2853 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002854
Walter Dörwald067db482006-03-15 22:17:27 +00002855- Patch #1359365: Calling next() on a closed StringIO.String object raises
2856 a ValueError instead of a StopIteration now (like file and cString.String do).
2857 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been

2939 is that SHA-256 is a good choice for the time being, but
2940 that research should continue, and other alternatives may
2941 arise from this research. The larger SHA's also seem OK."

Thomas Hellerd6c6e222005-01-20 19:20:16 +00003117- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3118
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003119- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3120
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003121- Enhancements to the csv module:
3122
3123 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003124 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003125 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003126 + Dialect parameter parsing has been re-implemented to improve error
3127 reporting.
3128 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3129 dictates.
3130 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003131 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003132 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003133 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3134 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003135 + reader now allows \r characters to be quoted (previously it only allowed
3136 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003137 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003138 + Dialect classes passed to the module are no longer instantiated by
3139 the module before being parsed (the former validation scheme required
3140 this, but the mechanism was unreliable).
3141 + The dialect registry now contains instances of the internal
3142 C-coded dialect type, rather than references to python objects.
3143 + the internal c-coded dialect type is now immutable.
3144 + register_dialect now accepts the same keyword dialect specifications
3145 as the reader and writer, allowing the user to register dialects
3146 without first creating a dialect class.
3147 + a configurable limit to the size of parsed fields has been added -
3148 previously, an unmatched quote character could result in the entire
3149 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003150 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003151 the parser field size limit (returning the former limit). The initial
3152 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003153 + A line_num attribute has been added to the reader object, which tracks
3154 the number of lines read from the source iterator. This is not
3155 the same as the number of records returned, as records can span
3156 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003157 + reader and writer objects were not being registered with the cyclic-GC.
3158 This has been fixed.
3159
Brett Cannone6539c42005-01-08 02:43:53 +00003160- _DummyThread objects in the threading module now delete self.__block that is
3161 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3162 lock primitives tend to be limited in number and thus should not be wasted on
3163 a _DummyThread object. Fixes bug #1089632.
3164
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003165- The imghdr module now detects Exif files.
3166
Raymond Hettinger6065d322004-12-20 23:51:53 +00003167- StringIO.truncate() now correctly adjusts the size attribute.
3168 (Bug #951915).
3169
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003170- locale.py now uses an updated locale alias table (built using
3171 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3172 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003173 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003174
Raymond Hettinger3557f422004-12-07 12:02:02 +00003175- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3176
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003177- the pickle module no longer accepts the deprecated None option in the
3178 args tuple returned by __reduce__().
3179
Brett Cannon84667c02004-12-07 03:25:18 +00003180- optparse now optionally imports gettext. This allows its use in setup.py.
3181
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003182- the pickle module no longer uses the deprecated bin parameter.
3183
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003184- the shelve module no longer uses the deprecated binary parameter.
3185
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003186- the pstats module no longer uses the deprecated ignore() method.
3187
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003188- the filecmp module no longer uses the deprecated use_statcache argument.
3189
Raymond Hettinger664347b2004-12-04 21:21:53 +00003190- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3191 extended or overridden by subclasses. Formerly, the subclassed method would
3192 be ignored by the rest of the module. (Bug #1078905).
3193
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003194- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003195 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003196
Walter Dörwald36733692004-12-22 12:50:50 +00003197- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3198 once when a size argument is given. This prevents a buffer overflow in the
3199 tokenizer with very long source lines.
3200
Barry Warsaw538561e2006-01-01 21:48:54 +00003201- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3202 immediately after creating the object, without any intervening
3203 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003204
Skip Montanaro05885812005-01-16 20:48:27 +00003205- The reconvert.quote function can now emit triple-quoted strings. The
3206 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003207
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003208- ``UserString.MutableString`` now supports negative indices in
3209 ``__setitem__`` and ``__delitem__``
3210
Greg Ward40407942005-03-05 02:53:17 +00003211- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3212 correctly.
3213
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003214- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3215 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3216 character even if the user has passed a size parameter to get a proper
3217 line ending. Remove the special handling of a "\r\n" that has been split
3218 between two lines.
3219
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003220- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3221 about illegal code points. The codec now supports PEP 293 style error
3222 handlers.
3223
Walter Dörwald78a78b02005-09-01 12:04:29 +00003224- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003225 from the input stream, so that the output is a byte string in the correct
3226 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003227
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003228- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3229 considering it exactly like a '*'.
3230
Walter Dörwald007f8df2005-10-09 19:42:27 +00003231- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3232 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003233
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003234- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3235
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003236- Patch #1413711: Certain patterns of differences were making difflib
3237 touch the recursion limit.
3238
Walter Dörwald58917a62006-03-31 15:26:22 +00003239- Bug #947906: An object oriented interface has been added to the calendar
3240 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003241 called as a script (e.g. via ``python -mcalendar``). Localized month and
3242 weekday names can be ouput (even if an exotic encoding is used) using
3243 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003244
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003245Build

3247
Neal Norwitz602d3392006-03-31 08:21:40 +00003248- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3249 by using -mieee gcc option.
3250

3252
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003253- Build support for Win64-AMD64 was added.
3254
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003255- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3256
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003257- Patch #881820: look for openpty and forkpty also in libbsd.
3258
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003259- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3260 The zlib module is now builtin on Windows.
3261
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003262- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3263
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003264- Bug #1189330: configure did not correctly determine the necessary
3265 value of LINKCC if python was built with GCC 4.0.
3266
Trent Mick8321b422005-07-26 02:29:21 +00003267- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3268 vulnerability in zlib 1.2.1 and 1.2.2.
3269
Brett Cannon08cd5982005-04-24 22:26:38 +00003270- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3271 flags that change binary compatibility. Changes were also made to
3272 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003273 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003274
Bob Ippolitoed233462005-03-29 13:47:59 +00003275- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3276 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3277 no longer exists). This configure patch makes things right.
3278
Martin v. Löwise2713be2005-03-08 15:03:08 +00003279- Bug #1158607: Build with --disable-unicode again.
3280
Brett Cannon46d96232005-02-16 00:07:19 +00003281- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3282 defined. Discovered as a result of not being able to build on OS X.
3283
Brett Cannon516592f2004-12-07 00:42:59 +00003284- setup.py now uses the directories specified in LDFLAGS using the -L option
3285 and in CPPFLAGS using the -I option for adding library and include
3286 directories, respectively, for compiling extension modules against. This has
3287 led to the core being compiled using the values in CPPFLAGS. It also removes
3288 the need for the special-casing of both DarwinPorts and Fink for darwin since
3289 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3290 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3291 Fink, ``-I/opt/local/include`` for DarwinPorts).
3292
Brett Cannon43802422005-02-10 20:48:03 +00003293- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3294 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3295 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3296 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003298C API
3299-----
3300
Tim Petersc9d78aa2006-03-26 23:27:58 +00003301- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3302 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3303 is obtained via the ``PyObject_`` family, it must be released via the
3304 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3305 always been officially true, but when Python's small-object allocator was
3306 introduced, an attempt was made to cater to a few extension modules
3307 discovered at the time that obtained memory via ``PyObject_New`` but
3308 released it via ``PyMem_DEL``. It's years later, and if such code still
3309 exists it will fail now (probably with segfaults, but calling wrong
3310 low-level memory management functions can yield many symptoms).
3311
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003312- Added a C API for set and frozenset objects.
3313
Raymond Hettinger66517482004-12-03 11:45:13 +00003314- Removed PyRange_New().
3315
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003316- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3317 mapping argument now. This string is used as a mapping table. Byte values
3318 greater than the length of the string and 0xFFFE are treated as undefined
3319 mappings.
