Anthony Baxter51bcb682006-04-05 14:51:42 +00007What's New in Python 2.5 alpha 2?
8=================================

11
12Core and builtins
13-----------------
14
Neal Norwitz61546162006-04-14 05:20:28 +000015- Bug #1454485, array.array('u') could crash the interpreter. This was
16 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
17 to unicode when it didn't make sense. 'u#' now requires a unicode string.
18
19- Py_UNICODE is unsigned. It was always documented as unsigned, but
20 due to a bug had a signed value in previous versions.
21
Tim Peters3a5e8b12006-04-11 01:44:07 +000022- Patch #837242: ``id()`` of any Python object always gives a positive
23 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
24 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000025 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000026 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000027
Tim Peters3a5e8b12006-04-11 01:44:07 +000028 def __hash__(self):
29 return id(self) # WRONG
30
31 because a hash result must be a (short) Python int but it was always
32 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000033 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000034 was always usable as a hash value before this patch. That's no longer
35 necessarily so.
36
37- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000038 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000039 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000040 #1454844)
41
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000042- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
43 involving generators that have paused outside of any ``try`` or ``with``
44 blocks. (In 2.5a1, a paused generator that was part of a reference
45 cycle could not be garbage collected, regardless of whether it was
46 paused in a ``try`` or ``with`` block.)

49-----------------
50
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000051- Bug #1467952: os.listdir() now correctly raises an error if readdir()
52 fails with an error condition.
53
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000054- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
55
56- Bug #1117761: bsddb.*open() no longer raises an exception when using
57 the cachesize parameter.
58
59- Bug #1149413: bsddb.*open() no longer raises an exception when using
60 a temporary db (file=None) with the 'n' flag to truncate on open.
61
62- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
63 as older versions cause excessive test failures.

66-------
67
Anthony Baxtere29002c2006-04-12 12:07:31 +000068- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
69 Windows. Bug #1469163.
70
Phillip J. Eby47032112006-04-11 01:07:43 +000071- The warnings, linecache, inspect, traceback, site, and doctest modules
72 were updated to work correctly with modules imported from zipfiles or
73 via other PEP 302 __loader__ objects.
74
Martin v. Löwis17de8ff2006-04-10 15:55:37 +000075- Patch #1467770: Reduce usage of subprocess._active to processes which
76 the application hasn't waited on.
77
Martin v. Löwisb04dee92006-04-10 08:34:21 +000078- Patch #1462222: Fix Tix.Grid.
79
Neal Norwitza31bf182006-04-09 03:35:43 +000080- Fix exception when doing glob.glob('anything*/')

83-----
84
Martin v. Löwis0f48d982006-04-14 14:34:26 +000085- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
86 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +000087 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +000088 CXX from --with-cxx-main, see description in README.
89
Martin v. Löwis10acfd02006-04-10 12:39:36 +000090- Patch #1429775: Link extension modules with the shared libpython.

Phillip J. Eby51dd7d92006-04-11 01:21:31 +000098- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
99 it separately and by hand. It also wasn't cleaning up its changes to
100 the current Decimal context.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000113Core and builtins
114-----------------
115
Martin v. Löwisea62d252006-04-03 10:56:49 +0000116- Bug #1421664: sys.stderr.encoding is now set to the same value as
117 sys.stdout.encoding.
118
Neal Norwitz92e212f2006-04-03 04:48:37 +0000119- __import__ accepts keyword arguments.
120
Georg Brandlccadf842006-03-31 18:54:53 +0000121- Patch #1460496: round() now accepts keyword arguments.
122
Anthony Baxter262c00a2006-03-30 10:53:17 +0000123- Fixed bug #1459029 - unicode reprs were double-escaped.
124
Hye-Shik Changd478f342006-03-23 12:32:36 +0000125- Patch #1396919: The system scope threads are reenabled on FreeBSD
126 5.4 and later versions.
127
Neal Norwitze98ccf62006-03-23 05:39:47 +0000128- Bug #1115379: Compiling a Unicode string with an encoding declaration
129 now gives a SyntaxError.
130
Georg Brandlabd1ff82006-03-18 07:59:59 +0000131- Previously, Python code had no easy way to access the contents of a
132 cell object. Now, a ``cell_contents`` attribute has been added
133 (closes patch #1170323).
134
Tim Peterscf79aac2006-03-16 01:14:46 +0000135- Patch #1123430: Python's small-object allocator now returns an arena to
136 the system ``free()`` when all memory within an arena becomes unused
137 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
138 freed. Some applications will see a drop in virtual memory size now,
139 especially long-running applications that, from time to time, temporarily
140 use a large number of small objects. Note that when Python returns an
141 arena to the platform C's ``free()``, there's no guarantee that the
142 platform C will in turn return that memory to the operating system. The
143 effect of the patch is to stop making that impossible, and in tests it
144 appears to be effective at least on Microsoft C and gcc-based systems.
145 Thanks to Evan Jones for hard work and patience.
146
Georg Brandl533ff6f2006-03-08 18:09:27 +0000147- Patch #1434038: property() now uses the getter's docstring if there is
148 no "doc" argument given. This makes it possible to legitimately use
149 property() as a decorator to produce a read-only property.
150
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000151- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
152 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
153 of requiring an int or long in slicing and a few other contexts, enabling
154 other objects (e.g. Numeric Python's integers) to be used as slice indices.
155
Neal Norwitz995acdf2006-03-07 05:01:00 +0000156- Fixed various bugs reported by Coverity's Prevent tool.
157
Brett Cannonbf364092006-03-01 04:25:17 +0000158- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
159 new exception base class, BaseException, which has a new message attribute.
160 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
161 Raising a string exception now raises a DeprecationWarning.
162
Thomas Woutersfb609f42006-02-28 16:37:25 +0000163- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
164 explicitly relative, using 'from .module import name' to mean 'from the same
165 package as this module is in. Imports without dots still default to the
166 old relative-then-absolute, unless 'from __future__ import
167 absolute_import' is used.
168
Brett Cannona7446e32006-02-27 23:39:10 +0000169- Properly check if 'warnings' raises an exception (usually when a filter set
170 to "error" is triggered) when raising a warning for raising string
171 exceptions.
172
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000173- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000174 The name was removed from Include/code.h.
175
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000176- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000177
Guido van Rossum1968ad32006-02-25 22:38:04 +0000178- Patch 1433928:
179 - The copy module now "copies" function objects (as atomic objects).
180 - dict.__getitem__ now looks for a __missing__ hook before raising
181 KeyError.
182
Tim Peters84ef21c2006-02-28 20:39:06 +0000183- PEP 343: with statement implemented. Needs ``from __future__ import
184 with_statement``. Use of 'with' as a variable will generate a warning.
185 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000186 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000187 The following objects have __context__ methods:
188 - The built-in file type.
189 - The thread.LockType type.
190 - The following types defined by the threading module:
191 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
192 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000193
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000194- Fix the encodings package codec search function to only search
195 inside its own package. Fixes problem reported in patch #1433198.
196
197 Note: Codec packages should implement and register their own
198 codec search function. PEP 100 has the details.
199
Martin v. Löwis18e16552006-02-15 17:27:45 +0000200- PEP 353: Using ssize_t as the index type.
201
Neal Norwitzfc76d632006-01-10 06:03:13 +0000202- Patch #1400181, fix unicode string formatting to not use the locale.
203 This is how string objects work. u'%f' could use , instead of .
204 for the decimal point. Now both strings and unicode always use periods.
205
Neal Norwitz671b9e32006-01-09 07:07:12 +0000206- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
207 configure would break checking curses.h.
208
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000209- Bug #959576: The pwd module is now builtin. This allows Python to be
210 built on UNIX platforms without $HOME set.
211
Neal Norwitzc10978f2005-12-19 06:07:16 +0000212- Bug #1072182, fix some potential problems if characters are signed.
213
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000214- Bug #889500, fix line number on SyntaxWarning for global declarations.
215
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000216- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
217
Neal Norwitze7214a12005-12-18 05:03:17 +0000218- Support for converting hex strings to floats no longer works.
219 This was not portable. float('0x3') now raises a ValueError.
220
Barry Warsaw2a38a862005-12-18 01:27:35 +0000221- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000222 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000223 is now displayed in interactive prompt banner.
224
Georg Brandlfa166682005-12-17 21:45:17 +0000225- Implementation of PEP 341 - Unification of try/except and try/finally.
226 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000227 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000228
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000229- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
230 now encodes backslash correctly.
231
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000232- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
233
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000234- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000235 and long longs.
236
Neal Norwitz67715f02005-11-09 06:59:35 +0000237- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000238 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000239 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000240
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000241- Replaced most Unicode charmap codecs with new ones using the
242 new Unicode translate string feature in the builtin charmap
243 codec; the codecs were created from the mapping tables available
244 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
245 encodings now include a mapping for the Apple logo)
246
Tim Peterse3547fd2005-12-16 23:13:57 +0000247- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000248
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000249- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000250
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000251- A new AST parser implementation was completed. The abstract
252 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000253 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000254
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000255- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000256 The following code now raises a SyntaxError: foo(a = i for i in range(10))
257
Neal Norwitz708e51a2005-10-03 04:48:15 +0000258- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
259
Neal Norwitz11bd1192005-10-03 00:54:56 +0000260- SF Bug #887946: fix segfault when redirecting stdin from a directory.
261 Provide a warning when a directory is passed on the command line.
262
Neal Norwitz40d37812005-10-02 01:48:49 +0000263- Fix segfault with invalid coding.
264
265- SF bug #772896: unknown encoding results in MemoryError.
266
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000267- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000268 supported a __len__() method which evaluated to False when the iterator
269 was empty.
270
Guido van Rossum630db602005-09-20 18:49:54 +0000271- On 64-bit platforms, when __len__() returns a value that cannot be
272 represented as a C int, raise OverflowError.
273
Skip Montanarof8948ca2005-09-19 03:54:46 +0000274- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000275 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000276
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000277- SF bug #893549: parsing keyword arguments was broken with a few format
278 codes.
279
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000280- Changes donated by Elemental Security to make it work on AIX 5.3
281 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
282 bug #105470: test_pwd fails on 64bit system (Opteron).
283
Guido van Rossum539c6622005-09-14 17:49:54 +0000284- Changes donated by Elemental Security to make it work on HP-UX 11 on
285 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
286
Georg Brandl4550b8d2005-08-26 06:43:52 +0000287- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000288 (fixes bug #1119418).
289
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000290- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
291
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000292- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
293 exceptions that cause a function to exit.
294
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000295- The implementation of set() and frozenset() was revised to use its
296 own internal data structure. Memory consumption is reduced by 1/3
297 and there are modest speed-ups as well. The API is unchanged.
298
Tim Petersde7990b2005-07-17 23:45:23 +0000299- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
300
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000301- SF bug #1229429: PyObject_CallMethod failed to decrement some
302 reference counts in some error exit cases.
303
Tim Petersecc6e6a2005-07-10 22:30:55 +0000304- SF bug #1185883: Python's small-object memory allocator took over
305 a block managed by the platform C library whenever a realloc specified
306 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000307 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000308 portable way to copy data from the C-managed block into Python's
309 small-object space without risking a memory fault. Python's small-object
310 realloc now leaves such blocks under the control of the platform C
311 realloc.
312
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000313- SF bug #1232517: An overflow error was not detected properly when
314 attempting to convert a large float to an int in os.utime().
315
Raymond Hettinger3296e692005-06-29 23:29:56 +0000316- SF bug #1224347: hex longs now print with lowercase letters just
317 like their int counterparts.
318
Michael W. Hudson188d4362005-06-20 16:52:57 +0000319- SF bug #1163563: the original fix for bug #1010677 ("thread Module
320 Breaks PyGILState_Ensure()") broke badly in the case of multiple
321 interpreter states; back out that fix and do a better job (see
322 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
323 for a longer write-up of the problem).
324
Michael W. Hudsondf888462005-06-03 14:41:55 +0000325- SF patch #1180995: marshal now uses a binary format by default when
326 serializing floats.
327
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000328- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
329 the routines that promise to produce IEEE 754 binary representations
330 of floats now simply copy bytes around.
331
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000332- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
333 278.
334
Brett Cannonc3647ac2005-04-26 03:45:26 +0000335- patch #1109424: int, long, float, complex, and unicode now check for the
336 proper magic slot for type conversions when subclassed. Previously the
337 magic slot was ignored during conversion. Semantics now match the way
338 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000339 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000340 PyNumber_*().
341 Thanks Walter Dörwald.
342
Barry Warsawc8d907c2005-04-19 23:43:40 +0000343- Descriptors defined in C with a PyGetSetDef structure, where the setter is
344 NULL, now raise an AttributeError when attempting to set or delete the
345 attribute. Previously a TypeError was raised, but this was inconsistent
346 with the equivalent pure-Python implementation.
347
Michael W. Hudson774479c2005-04-18 08:46:17 +0000348- It is now safe to call PyGILState_Release() before
349 PyEval_InitThreads() (note that if there is reason to believe there
350 are multiple threads around you still must call PyEval_InitThreads()
351 before using the Python API; this fix is for extension modules that
352 have no way of knowing if Python is multi-threaded yet).
353
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000354- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
355 disabled caused a crash.
356
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000357- Bug #1165306: instancemethod_new allowed the creation of a method
358 with im_class == im_self == NULL, which caused a crash when called.
359
Tim Petersecc6e6a2005-07-10 22:30:55 +0000360- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000361 fixes the crash seen in bug #1165761
362
Raymond Hettinger96229b12005-03-11 06:49:40 +0000363- Added two new builtins, any() and all().
364
Brett Cannon409d8f22005-03-05 06:47:57 +0000365- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000366 (e.g., ``class C(): pass`` is no longer a syntax error).
367 Patch #1176012 added support to the 'parser' module and 'compiler' package
368 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000369
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000370- Patch #1115086: Support PY_LONGLONG in structmember.
371
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000372- Bug #1155938: new style classes did not check that __init__() was
373 returning None.
374
Tim Petersecc6e6a2005-07-10 22:30:55 +0000375- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000376 ('\') with a specific error message.
377
Martin v. Löwisff232d72005-03-03 09:24:38 +0000378- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
379
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000380- Bug #1124295: the __name__ attribute of file objects was
381 inadvertently made inaccessible in restricted mode.
382
Tim Petersecc6e6a2005-07-10 22:30:55 +0000383- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000384 an ferror() call.
385
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000386- min() and max() now support key= arguments with the same meaning as in
387 list.sort().
388
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000389- The peephole optimizer now performs simple constant folding in expressions:
390 (2+3) --> (5).
391
Raymond Hettingera422c342005-01-11 03:03:27 +0000392- set and frozenset objects can now be marshalled. SF #1098985.
393
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000394- Bug #1077106: Poor argument checking could cause memory corruption
395 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000396
Jeremy Hyltonab630502005-02-04 18:44:06 +0000397- The parser did not complain about future statements in illegal
398 positions. It once again reports a syntax error if a future
399 statement occurs after anything other than a doc string.
400
Neil Schemenauercf52c072005-08-12 17:34:58 +0000401- Change the %s format specifier for str objects so that it returns a
402 unicode instance if the argument is not an instance of basestring and
403 calling __str__ on the argument returns a unicode instance.
404
Tim Petersf4e69282006-02-27 17:15:31 +0000405- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
406 current thread state when the auto-GIL-state machinery knows about
407 it (since the thread state is being deleted, continuing to remember it
408 can't help, but can hurt if another thread happens to get created with
409 the same thread id).
410
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000411Extension Modules

435 SS2 (single-shift 2) escape sequences correctly.
436
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000437- The unicodedata module was updated to the 4.1 version of the Unicode
438 database. The 3.2 version is still available as unicodedata.db_3_2_0
439 for applications that require this specific version (such as IDNA).
440
Neal Norwitzb62c4332006-03-04 18:35:47 +0000441- The timing module is no longer built by default. It was deprecated
442 in PEP 4 in Python 2.0 or earlier.
443
Guido van Rossum1968ad32006-02-25 22:38:04 +0000444- Patch 1433928: Added a new type, defaultdict, to the collections module.
445 This uses the new __missing__ hook behavior added to dict (see above).
446
Georg Brandldbd83392006-02-20 09:42:33 +0000447- Bug #854823: socketmodule now builds on Sun platforms even when
448 INET_ADDRSTRLEN is not defined.
449
Georg Brandlf4f44152006-02-18 22:29:33 +0000450- Patch #1393157: os.startfile() now has an optional argument to specify
451 a "command verb" to invoke on the file.
452
Neal Norwitz082b2df2006-02-07 07:04:46 +0000453- Bug #876637, prevent stack corruption when socket descriptor

461 than the system default domain.
462
Martin v. Löwis14694662006-02-03 12:54:16 +0000463- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
464 are reported, the limit on path name lengths is removed, and stat reports
465 WindowsError now (instead of OSError).
466

Raymond Hettingera6b45cc2004-12-07 07:05:57 +0000585- the cPickle module no longer accepts the deprecated None option in the
586 args tuple returned by __reduce__().
587
Raymond Hettingerb2594052004-12-05 09:25:51 +0000588- itertools.islice() now accepts None for the start and step arguments.
589 This allows islice() to work more readily with slices:

609 in attribute values.
610
Anthony Baxterc51ee692006-04-01 00:57:31 +0000611- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000612 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000613 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000614 module will not be built.
615
Tim Petersc17976e2006-04-01 00:26:53 +0000616- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
617 aren't officially supported here, and trying to use them will probably
618 raise an exception some day. But dicts have been allowed, and "mostly
619 worked", so support for them won't go away without warning.
620
Georg Brandl338ef7d2006-03-31 18:42:16 +0000621- Bug #1445068: getpass.getpass() can now be given an explicit stream
622 argument to specify where to write the prompt.
623
Georg Brandl22ec80b2006-03-31 18:25:44 +0000624- Patch #1462313, bug #1443328: the pickle modules now can handle classes

630 key to be used for signing the uploaded code.
631
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000632- Queue.Queue objects now support .task_done() and .join() methods
633 to make it easier to monitor when daemon threads have completed
634 processing all enqueued tasks. Patch #1455676.
635
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000636- popen2.Popen objects now preserve the command in a .cmd attribute.

639
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000640- email 4.0 package now integrated. This is largely the same as the email 3.0
641 package that was included in Python 2.3, except that PEP 8 module names are
642 now used (e.g. mail.message instead of email.Message). The MIME classes
643 have been moved to a subpackage (e.g. email.mime.text instead of
644 email.MIMEText). The old names are still supported for now. Several
645 deprecated Message methods have been removed and lots of bugs have been
646 fixed. More details can be found in the email package documentation.
647
Walter Dörwald40108c92006-03-27 08:15:44 +0000648- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
649 (a subclass of tuple) that provides incremental decoders and encoders
650 (a way to use stateful codecs without the stream API). Python functions
651 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
652 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
653 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000654
Walter Dörwald067db482006-03-15 22:17:27 +0000655- Patch #1359365: Calling next() on a closed StringIO.String object raises
656 a ValueError instead of a StopIteration now (like file and cString.String do).
657 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
658 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000659

734 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
735 Ronald L. Rivest offered this advice for Python:
736
737 "The consensus of researchers in this area (at least as
738 expressed at the NIST Hash Function Workshop 10/31/05),
739 is that SHA-256 is a good choice for the time being, but
740 that research should continue, and other alternatives may
741 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000742
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000743- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl9166e1a2005-06-04 09:20:03 +0000843- Bug #1196315: fix weakref.WeakValueDictionary constructor.
844
Georg Brandl268e61c2005-06-03 14:28:50 +0000845- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
846 component of the path.
847
Skip Montanaro174dd222005-05-14 20:54:16 +0000848- Patch #1120353: The xmlrpclib module provides better, more transparent,
849 support for datetime.{datetime,date,time} objects. With use_datetime set
850 to True, applications shouldn't have to fiddle with the DateTime wrapper
851 class at all.
852
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000853- distutils.commands.upload was added to support uploading distribution
854 files to PyPI.
855
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000856- distutils.commands.register now encodes the data as UTF-8 before posting
857 them to PyPI.
858
Raymond Hettinger267b8682005-03-27 10:47:39 +0000859- decimal operator and comparison methods now return NotImplemented
860 instead of raising a TypeError when interacting with other types. This
861 allows other classes to implement __radd__ style methods and have them
862 work as expected.
863
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000864- Bug #1163325: Decimal infinities failed to hash. Attempting to
865 hash a NaN raised an InvalidOperation instead of a TypeError.
866
Tim Petersecc6e6a2005-07-10 22:30:55 +0000867- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +0000868 stream compression; add, for symmetry reasons, r:* as a synonym of r.
869
Martin v. Löwis00a73e72005-03-04 19:40:34 +0000870- Patch #1043890: Add extractall method to tarfile.
871
Martin v. Löwisc72dd382005-03-04 13:50:17 +0000872- Patch #1075887: Don't require MSVC in distutils if there is nothing
873 to build.
874
Martin v. Löwis637431b2005-03-03 23:12:42 +0000875- Patch #1103407: Properly deal with tarfile iterators when untarring
876 symbolic links on Windows.
877
Tim Petersecc6e6a2005-07-10 22:30:55 +0000878- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +0000879 profile.py if available.
880
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +0000881- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
882
Martin v. Löwisc5574e82005-03-03 10:57:37 +0000883- Patch #1117454: Remove code to special-case cookies without values
884 in LWPCookieJar.
885
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +0000886- Patch #1117339: Add cookielib special name tests.
887
Martin v. Löwise869eb12005-03-03 09:46:07 +0000888- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
889
Martin v. Löwisf2a8d632005-03-03 08:35:22 +0000890- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
891
Martin v. Löwisdf241532005-03-03 08:17:42 +0000892- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
893
Martin v. Löwis8ed338a2005-03-03 08:12:27 +0000894- Patch #1104111: Alter setup.py --help and --help-commands.
895
Martin v. Löwis4afe1542005-03-01 08:09:28 +0000896- Patch #1121234: Properly cleanup _exit and tkerror commands.
897
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +0000898- Patch #1049151: xdrlib now unpacks booleans as True or False.
899
Raymond Hettingerbab41432005-02-05 01:31:19 +0000900- Fixed bug in a NameError bug in cookielib. Patch #1116583.
901
Guido van Rossumd0641422005-02-03 15:01:24 +0000902- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
903 disables recursive traversal through instance attributes, which can
904 be exploited in various ways.
905
Tim Peterse3547fd2005-12-16 23:13:57 +0000906- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000907 flags on the HTTP listening socket.
908
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000909- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
910 Fixed by reading the HTTP body in chunks instead of one big socket.read().
911
Tim Peterse3547fd2005-12-16 23:13:57 +0000912- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000913 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
914
Martin v. Löwis1d11de62005-01-29 13:29:23 +0000915- Bug #1110478: Revert os.environ.update to do putenv again.
916
Thomas Hellerd6c6e222005-01-20 19:20:16 +0000917- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
918
Martin v. Löwis22b457e2005-01-16 08:40:58 +0000919- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
920
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000921- Enhancements to the csv module:
922
923 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +0000924 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +0000925 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000926 + Dialect parameter parsing has been re-implemented to improve error
927 reporting.
928 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
929 dictates.
930 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000931 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000932 types, rather than any object than can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000933 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
934 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000935 + reader now allows \r characters to be quoted (previously it only allowed
936 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +0000937 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000938 + Dialect classes passed to the module are no longer instantiated by
939 the module before being parsed (the former validation scheme required
940 this, but the mechanism was unreliable).
941 + The dialect registry now contains instances of the internal
942 C-coded dialect type, rather than references to python objects.
943 + the internal c-coded dialect type is now immutable.
944 + register_dialect now accepts the same keyword dialect specifications
945 as the reader and writer, allowing the user to register dialects
946 without first creating a dialect class.
947 + a configurable limit to the size of parsed fields has been added -
948 previously, an unmatched quote character could result in the entire
949 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +0000950 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000951 the parser field size limit (returning the former limit). The initial
952 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +0000953 + A line_num attribute has been added to the reader object, which tracks
954 the number of lines read from the source iterator. This is not
955 the same as the number of records returned, as records can span
956 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000957 + reader and writer objects were not being registered with the cyclic-GC.
958 This has been fixed.
959
Brett Cannone6539c42005-01-08 02:43:53 +0000960- _DummyThread objects in the threading module now delete self.__block that is
961 inherited from _Thread since it uses up a lock allocated by 'thread'. The
962 lock primitives tend to be limited in number and thus should not be wasted on
963 a _DummyThread object. Fixes bug #1089632.
964
Raymond Hettinger97db05d2005-01-07 08:15:41 +0000965- The imghdr module now detects Exif files.
966
Raymond Hettinger6065d322004-12-20 23:51:53 +0000967- StringIO.truncate() now correctly adjusts the size attribute.
968 (Bug #951915).
969
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000970- locale.py now uses an updated locale alias table (built using
971 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
972 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000973 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000974
Raymond Hettinger3557f422004-12-07 12:02:02 +0000975- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
976
Raymond Hettingera6b45cc2004-12-07 07:05:57 +0000977- the pickle module no longer accepts the deprecated None option in the
978 args tuple returned by __reduce__().
979
Brett Cannon84667c02004-12-07 03:25:18 +0000980- optparse now optionally imports gettext. This allows its use in setup.py.
981
Raymond Hettinger3489cad2004-12-05 05:20:42 +0000982- the pickle module no longer uses the deprecated bin parameter.
983
Raymond Hettinger1bc82f82004-12-05 03:58:17 +0000984- the shelve module no longer uses the deprecated binary parameter.
985
Raymond Hettinger6c92d762004-12-05 03:28:00 +0000986- the pstats module no longer uses the deprecated ignore() method.
987
Raymond Hettingerf3fa9462004-12-05 01:58:09 +0000988- the filecmp module no longer uses the deprecated use_statcache argument.
989
Raymond Hettinger664347b2004-12-04 21:21:53 +0000990- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
991 extended or overridden by subclasses. Formerly, the subclassed method would
992 be ignored by the rest of the module. (Bug #1078905).
993
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000994- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000995 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000996
Walter Dörwald36733692004-12-22 12:50:50 +0000997- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
998 once when a size argument is given. This prevents a buffer overflow in the
999 tokenizer with very long source lines.
1000
Barry Warsaw538561e2006-01-01 21:48:54 +00001001- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1002 immediately after creating the object, without any intervening
1003 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001004
Skip Montanaro05885812005-01-16 20:48:27 +00001005- The reconvert.quote function can now emit triple-quoted strings. The
1006 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001007
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001008- ``UserString.MutableString`` now supports negative indices in
1009 ``__setitem__`` and ``__delitem__``
1010
Greg Ward40407942005-03-05 02:53:17 +00001011- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1012 correctly.
1013
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001014- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1015 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1016 character even if the user has passed a size parameter to get a proper
1017 line ending. Remove the special handling of a "\r\n" that has been split
1018 between two lines.
1019
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001020- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1021 about illegal code points. The codec now supports PEP 293 style error
1022 handlers.
1023
Walter Dörwald78a78b02005-09-01 12:04:29 +00001024- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001025 from the input stream, so that the output is a byte string in the correct
1026 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001027
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001028- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1029 considering it exactly like a '*'.
1030
Walter Dörwald007f8df2005-10-09 19:42:27 +00001031- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1032 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001033
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001034- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1035
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001036- Patch #1413711: Certain patterns of differences were making difflib
1037 touch the recursion limit.
1038
Walter Dörwald58917a62006-03-31 15:26:22 +00001039- Bug #947906: An object oriented interface has been added to the calendar
1040 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001041 called as a script (e.g. via ``python -mcalendar``). Localized month and
1042 weekday names can be ouput (even if an exotic encoding is used) using
1043 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001044

1047
Neal Norwitz602d3392006-03-31 08:21:40 +00001048- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1049 by using -mieee gcc option.
1050
Martin v. Löwis86d66262006-02-17 08:40:11 +00001051- Patch #1432345: Make python compile on DragonFly.
1052
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001053- Build support for Win64-AMD64 was added.
1054
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001055- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1056
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001057- Patch #881820: look for openpty and forkpty also in libbsd.
1058
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001059- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1060 The zlib module is now builtin on Windows.
1061
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001062- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1063
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001064- Bug #1189330: configure did not correctly determine the necessary
1065 value of LINKCC if python was built with GCC 4.0.
1066
Trent Mick8321b422005-07-26 02:29:21 +00001067- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1068 vulnerability in zlib 1.2.1 and 1.2.2.
1069
Brett Cannon08cd5982005-04-24 22:26:38 +00001070- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1071 flags that change binary compatibility. Changes were also made to
1072 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001073 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001074
Bob Ippolitoed233462005-03-29 13:47:59 +00001075- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1076 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1077 no longer exists). This configure patch makes things right.
1078
Martin v. Löwise2713be2005-03-08 15:03:08 +00001079- Bug #1158607: Build with --disable-unicode again.
1080
Brett Cannon46d96232005-02-16 00:07:19 +00001081- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1082 defined. Discovered as a result of not being able to build on OS X.
1083
Brett Cannon516592f2004-12-07 00:42:59 +00001084- setup.py now uses the directories specified in LDFLAGS using the -L option
1085 and in CPPFLAGS using the -I option for adding library and include
1086 directories, respectively, for compiling extension modules against. This has
1087 led to the core being compiled using the values in CPPFLAGS. It also removes
1088 the need for the special-casing of both DarwinPorts and Fink for darwin since
1089 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1090 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1091 Fink, ``-I/opt/local/include`` for DarwinPorts).
1092
Brett Cannon43802422005-02-10 20:48:03 +00001093- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1094 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1095 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1096 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001098C API
1099-----
1100
Tim Petersc9d78aa2006-03-26 23:27:58 +00001101- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1102 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1103 is obtained via the ``PyObject_`` family, it must be released via the
1104 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1105 always been officially true, but when Python's small-object allocator was
1106 introduced, an attempt was made to cater to a few extension modules
1107 discovered at the time that obtained memory via ``PyObject_New`` but
1108 released it via ``PyMem_DEL``. It's years later, and if such code still
1109 exists it will fail now (probably with segfaults, but calling wrong
1110 low-level memory management functions can yield many symptoms).
1111
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001112- Added a C API for set and frozenset objects.
1113
