Anthony Baxter51bcb682006-04-05 14:51:42 +00007What's New in Python 2.5 alpha 2?
8=================================
9
10*Release date: XX-XXX-2006*
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.)

Anthony Baxter51bcb682006-04-05 14:51:42 +000048Extension Modules
49-----------------
50
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000051- Patch #1191065: Fix preprocessor problems on systems where recvfrom
52 is a macro.
53
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000054- Bug #1467952: os.listdir() now correctly raises an error if readdir()
55 fails with an error condition.
56
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000057- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
58
59- Bug #1117761: bsddb.*open() no longer raises an exception when using
60 the cachesize parameter.
61
62- Bug #1149413: bsddb.*open() no longer raises an exception when using
63 a temporary db (file=None) with the 'n' flag to truncate on open.
64
65- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
66 as older versions cause excessive test failures.

69-------
70
Anthony Baxtere29002c2006-04-12 12:07:31 +000071- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
72 Windows. Bug #1469163.
73
Phillip J. Eby47032112006-04-11 01:07:43 +000074- The warnings, linecache, inspect, traceback, site, and doctest modules
75 were updated to work correctly with modules imported from zipfiles or
76 via other PEP 302 __loader__ objects.
77
Martin v. Löwis17de8ff2006-04-10 15:55:37 +000078- Patch #1467770: Reduce usage of subprocess._active to processes which
79 the application hasn't waited on.
80
Martin v. Löwisb04dee92006-04-10 08:34:21 +000081- Patch #1462222: Fix Tix.Grid.
82
Neal Norwitza31bf182006-04-09 03:35:43 +000083- Fix exception when doing glob.glob('anything*/')

86-----
87
Martin v. Löwisc90b17e2006-04-15 08:13:05 +000088- Patch #1161914: Add a python-config script.
Martin v. Löwis0f48d982006-04-14 14:34:26 +000089- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
90 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +000091 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +000092 CXX from --with-cxx-main, see description in README.
93
Martin v. Löwis10acfd02006-04-10 12:39:36 +000094- Patch #1429775: Link extension modules with the shared libpython.

Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000102- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
103 it separately and by hand. It also wasn't cleaning up its changes to
104 the current Decimal context.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000117Core and builtins
118-----------------
119
Martin v. Löwisea62d252006-04-03 10:56:49 +0000120- Bug #1421664: sys.stderr.encoding is now set to the same value as
121 sys.stdout.encoding.
122
Neal Norwitz92e212f2006-04-03 04:48:37 +0000123- __import__ accepts keyword arguments.
124
Georg Brandlccadf842006-03-31 18:54:53 +0000125- Patch #1460496: round() now accepts keyword arguments.
126
Anthony Baxter262c00a2006-03-30 10:53:17 +0000127- Fixed bug #1459029 - unicode reprs were double-escaped.
128
Hye-Shik Changd478f342006-03-23 12:32:36 +0000129- Patch #1396919: The system scope threads are reenabled on FreeBSD
130 5.4 and later versions.
131
Neal Norwitze98ccf62006-03-23 05:39:47 +0000132- Bug #1115379: Compiling a Unicode string with an encoding declaration
133 now gives a SyntaxError.
134
Georg Brandlabd1ff82006-03-18 07:59:59 +0000135- Previously, Python code had no easy way to access the contents of a
136 cell object. Now, a ``cell_contents`` attribute has been added
137 (closes patch #1170323).
138
Tim Peterscf79aac2006-03-16 01:14:46 +0000139- Patch #1123430: Python's small-object allocator now returns an arena to
140 the system ``free()`` when all memory within an arena becomes unused
141 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
142 freed. Some applications will see a drop in virtual memory size now,
143 especially long-running applications that, from time to time, temporarily
144 use a large number of small objects. Note that when Python returns an
145 arena to the platform C's ``free()``, there's no guarantee that the
146 platform C will in turn return that memory to the operating system. The
147 effect of the patch is to stop making that impossible, and in tests it
148 appears to be effective at least on Microsoft C and gcc-based systems.
149 Thanks to Evan Jones for hard work and patience.
150
Georg Brandl533ff6f2006-03-08 18:09:27 +0000151- Patch #1434038: property() now uses the getter's docstring if there is
152 no "doc" argument given. This makes it possible to legitimately use
153 property() as a decorator to produce a read-only property.
154
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000155- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
156 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
157 of requiring an int or long in slicing and a few other contexts, enabling
158 other objects (e.g. Numeric Python's integers) to be used as slice indices.
159
Neal Norwitz995acdf2006-03-07 05:01:00 +0000160- Fixed various bugs reported by Coverity's Prevent tool.
161
Brett Cannonbf364092006-03-01 04:25:17 +0000162- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
163 new exception base class, BaseException, which has a new message attribute.
164 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
165 Raising a string exception now raises a DeprecationWarning.
166
Thomas Woutersfb609f42006-02-28 16:37:25 +0000167- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
168 explicitly relative, using 'from .module import name' to mean 'from the same
169 package as this module is in. Imports without dots still default to the
170 old relative-then-absolute, unless 'from __future__ import
171 absolute_import' is used.
172
Brett Cannona7446e32006-02-27 23:39:10 +0000173- Properly check if 'warnings' raises an exception (usually when a filter set
174 to "error" is triggered) when raising a warning for raising string
175 exceptions.
176
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000177- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000178 The name was removed from Include/code.h.
179
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000180- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000181
Guido van Rossum1968ad32006-02-25 22:38:04 +0000182- Patch 1433928:
183 - The copy module now "copies" function objects (as atomic objects).
184 - dict.__getitem__ now looks for a __missing__ hook before raising
185 KeyError.
186
Tim Peters84ef21c2006-02-28 20:39:06 +0000187- PEP 343: with statement implemented. Needs ``from __future__ import
188 with_statement``. Use of 'with' as a variable will generate a warning.
189 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000190 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000191 The following objects have __context__ methods:
192 - The built-in file type.
193 - The thread.LockType type.
194 - The following types defined by the threading module:
195 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
196 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000197
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000198- Fix the encodings package codec search function to only search
199 inside its own package. Fixes problem reported in patch #1433198.
200
201 Note: Codec packages should implement and register their own
202 codec search function. PEP 100 has the details.
203
Martin v. Löwis18e16552006-02-15 17:27:45 +0000204- PEP 353: Using ssize_t as the index type.
205
Neal Norwitzfc76d632006-01-10 06:03:13 +0000206- Patch #1400181, fix unicode string formatting to not use the locale.
207 This is how string objects work. u'%f' could use , instead of .
208 for the decimal point. Now both strings and unicode always use periods.
209
Neal Norwitz671b9e32006-01-09 07:07:12 +0000210- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
211 configure would break checking curses.h.
212
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000213- Bug #959576: The pwd module is now builtin. This allows Python to be
214 built on UNIX platforms without $HOME set.
215
Neal Norwitzc10978f2005-12-19 06:07:16 +0000216- Bug #1072182, fix some potential problems if characters are signed.
217
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000218- Bug #889500, fix line number on SyntaxWarning for global declarations.
219
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000220- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
221
Neal Norwitze7214a12005-12-18 05:03:17 +0000222- Support for converting hex strings to floats no longer works.
223 This was not portable. float('0x3') now raises a ValueError.
224
Barry Warsaw2a38a862005-12-18 01:27:35 +0000225- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000226 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000227 is now displayed in interactive prompt banner.
228
Georg Brandlfa166682005-12-17 21:45:17 +0000229- Implementation of PEP 341 - Unification of try/except and try/finally.
230 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000231 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000232
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000233- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
234 now encodes backslash correctly.
235
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000236- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
237
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000238- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000239 and long longs.
240
Neal Norwitz67715f02005-11-09 06:59:35 +0000241- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000242 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000243 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000244
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000245- Replaced most Unicode charmap codecs with new ones using the
246 new Unicode translate string feature in the builtin charmap
247 codec; the codecs were created from the mapping tables available
248 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
249 encodings now include a mapping for the Apple logo)
250
Tim Peterse3547fd2005-12-16 23:13:57 +0000251- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000252
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000253- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000254
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000255- A new AST parser implementation was completed. The abstract
256 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000257 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000258
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000259- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000260 The following code now raises a SyntaxError: foo(a = i for i in range(10))
261
Neal Norwitz708e51a2005-10-03 04:48:15 +0000262- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
263
Neal Norwitz11bd1192005-10-03 00:54:56 +0000264- SF Bug #887946: fix segfault when redirecting stdin from a directory.
265 Provide a warning when a directory is passed on the command line.
266
Neal Norwitz40d37812005-10-02 01:48:49 +0000267- Fix segfault with invalid coding.
268
269- SF bug #772896: unknown encoding results in MemoryError.
270
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000271- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000272 supported a __len__() method which evaluated to False when the iterator
273 was empty.
274
Guido van Rossum630db602005-09-20 18:49:54 +0000275- On 64-bit platforms, when __len__() returns a value that cannot be
276 represented as a C int, raise OverflowError.
277
Skip Montanarof8948ca2005-09-19 03:54:46 +0000278- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000279 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000280
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000281- SF bug #893549: parsing keyword arguments was broken with a few format
282 codes.
283
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000284- Changes donated by Elemental Security to make it work on AIX 5.3
285 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
286 bug #105470: test_pwd fails on 64bit system (Opteron).
287
Guido van Rossum539c6622005-09-14 17:49:54 +0000288- Changes donated by Elemental Security to make it work on HP-UX 11 on
289 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
290
Georg Brandl4550b8d2005-08-26 06:43:52 +0000291- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000292 (fixes bug #1119418).
293
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000294- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
295
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000296- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
297 exceptions that cause a function to exit.
298
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000299- The implementation of set() and frozenset() was revised to use its
300 own internal data structure. Memory consumption is reduced by 1/3
301 and there are modest speed-ups as well. The API is unchanged.
302
Tim Petersde7990b2005-07-17 23:45:23 +0000303- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
304
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000305- SF bug #1229429: PyObject_CallMethod failed to decrement some
306 reference counts in some error exit cases.
307
Tim Petersecc6e6a2005-07-10 22:30:55 +0000308- SF bug #1185883: Python's small-object memory allocator took over
309 a block managed by the platform C library whenever a realloc specified
310 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000311 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000312 portable way to copy data from the C-managed block into Python's
313 small-object space without risking a memory fault. Python's small-object
314 realloc now leaves such blocks under the control of the platform C
315 realloc.
316
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000317- SF bug #1232517: An overflow error was not detected properly when
318 attempting to convert a large float to an int in os.utime().
319
Raymond Hettinger3296e692005-06-29 23:29:56 +0000320- SF bug #1224347: hex longs now print with lowercase letters just
321 like their int counterparts.
322
Michael W. Hudson188d4362005-06-20 16:52:57 +0000323- SF bug #1163563: the original fix for bug #1010677 ("thread Module
324 Breaks PyGILState_Ensure()") broke badly in the case of multiple
325 interpreter states; back out that fix and do a better job (see
326 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
327 for a longer write-up of the problem).
328
Michael W. Hudsondf888462005-06-03 14:41:55 +0000329- SF patch #1180995: marshal now uses a binary format by default when
330 serializing floats.
331
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000332- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
333 the routines that promise to produce IEEE 754 binary representations
334 of floats now simply copy bytes around.
335
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000336- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
337 278.
338
Brett Cannonc3647ac2005-04-26 03:45:26 +0000339- patch #1109424: int, long, float, complex, and unicode now check for the
340 proper magic slot for type conversions when subclassed. Previously the
341 magic slot was ignored during conversion. Semantics now match the way
342 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000343 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000344 PyNumber_*().
345 Thanks Walter Dörwald.
346
Barry Warsawc8d907c2005-04-19 23:43:40 +0000347- Descriptors defined in C with a PyGetSetDef structure, where the setter is
348 NULL, now raise an AttributeError when attempting to set or delete the
349 attribute. Previously a TypeError was raised, but this was inconsistent
350 with the equivalent pure-Python implementation.
351
Michael W. Hudson774479c2005-04-18 08:46:17 +0000352- It is now safe to call PyGILState_Release() before
353 PyEval_InitThreads() (note that if there is reason to believe there
354 are multiple threads around you still must call PyEval_InitThreads()
355 before using the Python API; this fix is for extension modules that
356 have no way of knowing if Python is multi-threaded yet).
357
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000358- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
359 disabled caused a crash.
360
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000361- Bug #1165306: instancemethod_new allowed the creation of a method
362 with im_class == im_self == NULL, which caused a crash when called.
363
Tim Petersecc6e6a2005-07-10 22:30:55 +0000364- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000365 fixes the crash seen in bug #1165761
366
Raymond Hettinger96229b12005-03-11 06:49:40 +0000367- Added two new builtins, any() and all().
368
Brett Cannon409d8f22005-03-05 06:47:57 +0000369- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000370 (e.g., ``class C(): pass`` is no longer a syntax error).
371 Patch #1176012 added support to the 'parser' module and 'compiler' package
372 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000373
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000374- Patch #1115086: Support PY_LONGLONG in structmember.
375
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000376- Bug #1155938: new style classes did not check that __init__() was
377 returning None.
378
Tim Petersecc6e6a2005-07-10 22:30:55 +0000379- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000380 ('\') with a specific error message.
381
Martin v. Löwisff232d72005-03-03 09:24:38 +0000382- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
383
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000384- Bug #1124295: the __name__ attribute of file objects was
385 inadvertently made inaccessible in restricted mode.
386
Tim Petersecc6e6a2005-07-10 22:30:55 +0000387- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000388 an ferror() call.
389
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000390- min() and max() now support key= arguments with the same meaning as in
391 list.sort().
392
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000393- The peephole optimizer now performs simple constant folding in expressions:
394 (2+3) --> (5).
395
Raymond Hettingera422c342005-01-11 03:03:27 +0000396- set and frozenset objects can now be marshalled. SF #1098985.
397
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000398- Bug #1077106: Poor argument checking could cause memory corruption
399 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000400
Jeremy Hyltonab630502005-02-04 18:44:06 +0000401- The parser did not complain about future statements in illegal
402 positions. It once again reports a syntax error if a future
403 statement occurs after anything other than a doc string.
404
Neil Schemenauercf52c072005-08-12 17:34:58 +0000405- Change the %s format specifier for str objects so that it returns a
406 unicode instance if the argument is not an instance of basestring and
407 calling __str__ on the argument returns a unicode instance.
408
Tim Petersf4e69282006-02-27 17:15:31 +0000409- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
410 current thread state when the auto-GIL-state machinery knows about
411 it (since the thread state is being deleted, continuing to remember it
412 can't help, but can hurt if another thread happens to get created with
413 the same thread id).
414

439 SS2 (single-shift 2) escape sequences correctly.
440
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000441- The unicodedata module was updated to the 4.1 version of the Unicode
442 database. The 3.2 version is still available as unicodedata.db_3_2_0
443 for applications that require this specific version (such as IDNA).
444
Neal Norwitzb62c4332006-03-04 18:35:47 +0000445- The timing module is no longer built by default. It was deprecated
446 in PEP 4 in Python 2.0 or earlier.
447
Guido van Rossum1968ad32006-02-25 22:38:04 +0000448- Patch 1433928: Added a new type, defaultdict, to the collections module.

466
Martin v. Löwis14694662006-02-03 12:54:16 +0000467- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
468 are reported, the limit on path name lengths is removed, and stat reports
469 WindowsError now (instead of OSError).
470

588
Raymond Hettingera6b45cc2004-12-07 07:05:57 +0000589- the cPickle module no longer accepts the deprecated None option in the
590 args tuple returned by __reduce__().
591
Raymond Hettingerb2594052004-12-05 09:25:51 +0000592- itertools.islice() now accepts None for the start and step arguments.
593 This allows islice() to work more readily with slices:
594 islice(s.start, s.stop, s.step)

613 in attribute values.
614
Anthony Baxterc51ee692006-04-01 00:57:31 +0000615- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000616 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000617 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000618 module will not be built.
619
Tim Petersc17976e2006-04-01 00:26:53 +0000620- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
621 aren't officially supported here, and trying to use them will probably
622 raise an exception some day. But dicts have been allowed, and "mostly
623 worked", so support for them won't go away without warning.
624
Georg Brandl338ef7d2006-03-31 18:42:16 +0000625- Bug #1445068: getpass.getpass() can now be given an explicit stream
626 argument to specify where to write the prompt.
627
Georg Brandl22ec80b2006-03-31 18:25:44 +0000628- Patch #1462313, bug #1443328: the pickle modules now can handle classes

634 key to be used for signing the uploaded code.
635
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000636- Queue.Queue objects now support .task_done() and .join() methods
637 to make it easier to monitor when daemon threads have completed
638 processing all enqueued tasks. Patch #1455676.
639
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000640- popen2.Popen objects now preserve the command in a .cmd attribute.
641

643
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000644- email 4.0 package now integrated. This is largely the same as the email 3.0
645 package that was included in Python 2.3, except that PEP 8 module names are
646 now used (e.g. mail.message instead of email.Message). The MIME classes
647 have been moved to a subpackage (e.g. email.mime.text instead of
648 email.MIMEText). The old names are still supported for now. Several
649 deprecated Message methods have been removed and lots of bugs have been
650 fixed. More details can be found in the email package documentation.
651
Walter Dörwald40108c92006-03-27 08:15:44 +0000652- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
653 (a subclass of tuple) that provides incremental decoders and encoders
654 (a way to use stateful codecs without the stream API). Python functions
655 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
656 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
657 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000658
Walter Dörwald067db482006-03-15 22:17:27 +0000659- Patch #1359365: Calling next() on a closed StringIO.String object raises
660 a ValueError instead of a StopIteration now (like file and cString.String do).
661 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
662 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000663
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000664- A regrtest option -w was added to re-run failed tests in verbose mode.

740
741 "The consensus of researchers in this area (at least as
742 expressed at the NIST Hash Function Workshop 10/31/05),
743 is that SHA-256 is a good choice for the time being, but
744 that research should continue, and other alternatives may
745 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000746

Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000843 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000844 the generate_tokens() function now accepts a callable argument that
845 terminates by raising StopIteration.
846
Georg Brandl9166e1a2005-06-04 09:20:03 +0000847- Bug #1196315: fix weakref.WeakValueDictionary constructor.
848
Georg Brandl268e61c2005-06-03 14:28:50 +0000849- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
850 component of the path.
851
Skip Montanaro174dd222005-05-14 20:54:16 +0000852- Patch #1120353: The xmlrpclib module provides better, more transparent,
853 support for datetime.{datetime,date,time} objects. With use_datetime set
854 to True, applications shouldn't have to fiddle with the DateTime wrapper
855 class at all.
856
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000857- distutils.commands.upload was added to support uploading distribution
858 files to PyPI.
859
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000860- distutils.commands.register now encodes the data as UTF-8 before posting
861 them to PyPI.
862
Raymond Hettinger267b8682005-03-27 10:47:39 +0000863- decimal operator and comparison methods now return NotImplemented
864 instead of raising a TypeError when interacting with other types. This
865 allows other classes to implement __radd__ style methods and have them
866 work as expected.
867
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000868- Bug #1163325: Decimal infinities failed to hash. Attempting to
869 hash a NaN raised an InvalidOperation instead of a TypeError.
870
Tim Petersecc6e6a2005-07-10 22:30:55 +0000871- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +0000872 stream compression; add, for symmetry reasons, r:* as a synonym of r.
873
Martin v. Löwis00a73e72005-03-04 19:40:34 +0000874- Patch #1043890: Add extractall method to tarfile.
875
Martin v. Löwisc72dd382005-03-04 13:50:17 +0000876- Patch #1075887: Don't require MSVC in distutils if there is nothing
877 to build.
878
Martin v. Löwis637431b2005-03-03 23:12:42 +0000879- Patch #1103407: Properly deal with tarfile iterators when untarring
880 symbolic links on Windows.
881
Tim Petersecc6e6a2005-07-10 22:30:55 +0000882- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +0000883 profile.py if available.
884
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +0000885- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
886
Martin v. Löwisc5574e82005-03-03 10:57:37 +0000887- Patch #1117454: Remove code to special-case cookies without values
888 in LWPCookieJar.
889
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +0000890- Patch #1117339: Add cookielib special name tests.
891
Martin v. Löwise869eb12005-03-03 09:46:07 +0000892- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
893
Martin v. Löwisf2a8d632005-03-03 08:35:22 +0000894- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
895
Martin v. Löwisdf241532005-03-03 08:17:42 +0000896- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
897
Martin v. Löwis8ed338a2005-03-03 08:12:27 +0000898- Patch #1104111: Alter setup.py --help and --help-commands.
899
Martin v. Löwis4afe1542005-03-01 08:09:28 +0000900- Patch #1121234: Properly cleanup _exit and tkerror commands.
901
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +0000902- Patch #1049151: xdrlib now unpacks booleans as True or False.
903
Raymond Hettingerbab41432005-02-05 01:31:19 +0000904- Fixed bug in a NameError bug in cookielib. Patch #1116583.
905
Guido van Rossumd0641422005-02-03 15:01:24 +0000906- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
907 disables recursive traversal through instance attributes, which can
908 be exploited in various ways.
909
Tim Peterse3547fd2005-12-16 23:13:57 +0000910- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000911 flags on the HTTP listening socket.
912
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000913- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
914 Fixed by reading the HTTP body in chunks instead of one big socket.read().
915
Tim Peterse3547fd2005-12-16 23:13:57 +0000916- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000917 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
918
Martin v. Löwis1d11de62005-01-29 13:29:23 +0000919- Bug #1110478: Revert os.environ.update to do putenv again.
920
Thomas Hellerd6c6e222005-01-20 19:20:16 +0000921- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
922
Martin v. Löwis22b457e2005-01-16 08:40:58 +0000923- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
924
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000925- Enhancements to the csv module:
926
927 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +0000928 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +0000929 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000930 + Dialect parameter parsing has been re-implemented to improve error
931 reporting.
932 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
933 dictates.
934 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000935 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000936 types, rather than any object than can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000937 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
938 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000939 + reader now allows \r characters to be quoted (previously it only allowed
940 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +0000941 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000942 + Dialect classes passed to the module are no longer instantiated by
943 the module before being parsed (the former validation scheme required
944 this, but the mechanism was unreliable).
945 + The dialect registry now contains instances of the internal
946 C-coded dialect type, rather than references to python objects.
947 + the internal c-coded dialect type is now immutable.
948 + register_dialect now accepts the same keyword dialect specifications
949 as the reader and writer, allowing the user to register dialects
950 without first creating a dialect class.
951 + a configurable limit to the size of parsed fields has been added -
952 previously, an unmatched quote character could result in the entire
953 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +0000954 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000955 the parser field size limit (returning the former limit). The initial
956 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +0000957 + A line_num attribute has been added to the reader object, which tracks
958 the number of lines read from the source iterator. This is not
959 the same as the number of records returned, as records can span
960 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000961 + reader and writer objects were not being registered with the cyclic-GC.
962 This has been fixed.
963
Brett Cannone6539c42005-01-08 02:43:53 +0000964- _DummyThread objects in the threading module now delete self.__block that is
965 inherited from _Thread since it uses up a lock allocated by 'thread'. The
966 lock primitives tend to be limited in number and thus should not be wasted on
967 a _DummyThread object. Fixes bug #1089632.
968
Raymond Hettinger97db05d2005-01-07 08:15:41 +0000969- The imghdr module now detects Exif files.
970
Raymond Hettinger6065d322004-12-20 23:51:53 +0000971- StringIO.truncate() now correctly adjusts the size attribute.
972 (Bug #951915).
973
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000974- locale.py now uses an updated locale alias table (built using
975 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
976 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000977 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000978
Raymond Hettinger3557f422004-12-07 12:02:02 +0000979- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
980
Raymond Hettingera6b45cc2004-12-07 07:05:57 +0000981- the pickle module no longer accepts the deprecated None option in the
982 args tuple returned by __reduce__().
983
Brett Cannon84667c02004-12-07 03:25:18 +0000984- optparse now optionally imports gettext. This allows its use in setup.py.
985
Raymond Hettinger3489cad2004-12-05 05:20:42 +0000986- the pickle module no longer uses the deprecated bin parameter.
987
Raymond Hettinger1bc82f82004-12-05 03:58:17 +0000988- the shelve module no longer uses the deprecated binary parameter.
989
Raymond Hettinger6c92d762004-12-05 03:28:00 +0000990- the pstats module no longer uses the deprecated ignore() method.
991
Raymond Hettingerf3fa9462004-12-05 01:58:09 +0000992- the filecmp module no longer uses the deprecated use_statcache argument.
993
Raymond Hettinger664347b2004-12-04 21:21:53 +0000994- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
995 extended or overridden by subclasses. Formerly, the subclassed method would
996 be ignored by the rest of the module. (Bug #1078905).
997
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000998- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000999 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001000
Walter Dörwald36733692004-12-22 12:50:50 +00001001- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1002 once when a size argument is given. This prevents a buffer overflow in the
1003 tokenizer with very long source lines.
1004
Barry Warsaw538561e2006-01-01 21:48:54 +00001005- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1006 immediately after creating the object, without any intervening
1007 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001008
Skip Montanaro05885812005-01-16 20:48:27 +00001009- The reconvert.quote function can now emit triple-quoted strings. The
1010 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001011
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001012- ``UserString.MutableString`` now supports negative indices in
1013 ``__setitem__`` and ``__delitem__``
1014
Greg Ward40407942005-03-05 02:53:17 +00001015- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1016 correctly.
1017
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001018- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1019 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1020 character even if the user has passed a size parameter to get a proper
1021 line ending. Remove the special handling of a "\r\n" that has been split
1022 between two lines.
1023
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001024- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1025 about illegal code points. The codec now supports PEP 293 style error
1026 handlers.
1027
Walter Dörwald78a78b02005-09-01 12:04:29 +00001028- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001029 from the input stream, so that the output is a byte string in the correct
1030 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001031
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001032- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1033 considering it exactly like a '*'.
1034
Walter Dörwald007f8df2005-10-09 19:42:27 +00001035- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1036 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001037
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001038- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1039
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001040- Patch #1413711: Certain patterns of differences were making difflib
1041 touch the recursion limit.
1042
Walter Dörwald58917a62006-03-31 15:26:22 +00001043- Bug #947906: An object oriented interface has been added to the calendar
1044 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001045 called as a script (e.g. via ``python -mcalendar``). Localized month and
1046 weekday names can be ouput (even if an exotic encoding is used) using
1047 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001048

1050-----
1051
Neal Norwitz602d3392006-03-31 08:21:40 +00001052- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1053 by using -mieee gcc option.
1054
Martin v. Löwis86d66262006-02-17 08:40:11 +00001055- Patch #1432345: Make python compile on DragonFly.
1056
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001057- Build support for Win64-AMD64 was added.
1058
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001059- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1060
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001061- Patch #881820: look for openpty and forkpty also in libbsd.
1062
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001063- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1064 The zlib module is now builtin on Windows.
1065
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001066- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1067
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001068- Bug #1189330: configure did not correctly determine the necessary
1069 value of LINKCC if python was built with GCC 4.0.
1070
Trent Mick8321b422005-07-26 02:29:21 +00001071- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1072 vulnerability in zlib 1.2.1 and 1.2.2.
1073
Brett Cannon08cd5982005-04-24 22:26:38 +00001074- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1075 flags that change binary compatibility. Changes were also made to
1076 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001077 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001078
Bob Ippolitoed233462005-03-29 13:47:59 +00001079- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1080 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1081 no longer exists). This configure patch makes things right.
1082
Martin v. Löwise2713be2005-03-08 15:03:08 +00001083- Bug #1158607: Build with --disable-unicode again.
1084
Brett Cannon46d96232005-02-16 00:07:19 +00001085- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1086 defined. Discovered as a result of not being able to build on OS X.
1087
Brett Cannon516592f2004-12-07 00:42:59 +00001088- setup.py now uses the directories specified in LDFLAGS using the -L option
1089 and in CPPFLAGS using the -I option for adding library and include
1090 directories, respectively, for compiling extension modules against. This has
1091 led to the core being compiled using the values in CPPFLAGS. It also removes
1092 the need for the special-casing of both DarwinPorts and Fink for darwin since
1093 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1094 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1095 Fink, ``-I/opt/local/include`` for DarwinPorts).
1096
Brett Cannon43802422005-02-10 20:48:03 +00001097- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1098 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1099 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1100 Closes bug #1096244. Thanks Gregory Bond.

1104
Tim Petersc9d78aa2006-03-26 23:27:58 +00001105- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1106 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1107 is obtained via the ``PyObject_`` family, it must be released via the
1108 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1109 always been officially true, but when Python's small-object allocator was
1110 introduced, an attempt was made to cater to a few extension modules
1111 discovered at the time that obtained memory via ``PyObject_New`` but
1112 released it via ``PyMem_DEL``. It's years later, and if such code still
1113 exists it will fail now (probably with segfaults, but calling wrong
1114 low-level memory management functions can yield many symptoms).

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001120- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1121 mapping argument now. This string is used as a mapping table. Byte values
1122 greater than the length of the string and 0xFFFE are treated as undefined
1123 mappings.
