Anthony Baxter51bcb682006-04-05 14:51:42 +00007What's New in Python 2.5 alpha 2?
8=================================
9
Anthony Baxterc7d00322006-04-27 02:11:24 +000010*Release date: 27-APR-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000015- Patch #1479181: split open() and file() from being aliases for each other.
16
Thomas Heller1b046642006-04-18 18:51:06 +000017- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
18 by converting these apis from macros into exported functions again:
19
20 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
21 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
22 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
23 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
24 PyRun_String Py_CompileString
25
Martin v. Löwis45294a92006-04-18 06:24:08 +000026- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
27
Martin v. Löwis19ab6c92006-04-16 18:55:50 +000028- All uses of PyStructSequence_InitType have been changed to initialize
29 the type objects only once, even if the interpreter is initialized
30 multiple times.
31
Neal Norwitz61546162006-04-14 05:20:28 +000032- Bug #1454485, array.array('u') could crash the interpreter. This was
33 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
34 to unicode when it didn't make sense. 'u#' now requires a unicode string.
35
36- Py_UNICODE is unsigned. It was always documented as unsigned, but
37 due to a bug had a signed value in previous versions.
38
Tim Peters3a5e8b12006-04-11 01:44:07 +000039- Patch #837242: ``id()`` of any Python object always gives a positive
40 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
41 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000042 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000043 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000044
Tim Peters3a5e8b12006-04-11 01:44:07 +000045 def __hash__(self):
46 return id(self) # WRONG
47
48 because a hash result must be a (short) Python int but it was always
49 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000050 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000051 was always usable as a hash value before this patch. That's no longer
52 necessarily so.
53
54- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000055 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000056 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000057 #1454844)
58
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000059- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
60 involving generators that have paused outside of any ``try`` or ``with``
61 blocks. (In 2.5a1, a paused generator that was part of a reference
62 cycle could not be garbage collected, regardless of whether it was
63 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +000064
Anthony Baxter51bcb682006-04-05 14:51:42 +000065Extension Modules
66-----------------
67
Martin v. Löwis86725192006-05-01 06:28:01 +000068- Calling Tk_Init twice is refused if the first call failed as that
69 may deadlock.
70
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000071- Patch #1191065: Fix preprocessor problems on systems where recvfrom
72 is a macro.
73
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000074- Bug #1467952: os.listdir() now correctly raises an error if readdir()
75 fails with an error condition.
76
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000077- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
78
79- Bug #1117761: bsddb.*open() no longer raises an exception when using
80 the cachesize parameter.
81
82- Bug #1149413: bsddb.*open() no longer raises an exception when using
83 a temporary db (file=None) with the 'n' flag to truncate on open.
84
85- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
86 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +000087
Armin Rigoa9017c32006-04-19 11:50:27 +000088- Patch #1062014: AF_UNIX sockets under Linux have a special
89 abstract namespace that is now fully supported.
90
Anthony Baxter51bcb682006-04-05 14:51:42 +000091Library
92-------
93
Georg Brandl1bb62302006-05-03 18:18:32 +000094- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
95 package.
96
Georg Brandl3583cff2006-04-30 18:14:54 +000097- Patch #1472854: make the rlcompleter.Completer class usable on non-
98 UNIX platforms.
99
Georg Brandlfa42bd72006-04-30 07:06:11 +0000100- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
101
Tim Peters711bf302006-04-25 03:31:36 +0000102- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
103 a doctest to be skipped (the code is not run, and the expected output
104 or exception is ignored).
105
Nick Coghlanda2268f2006-04-24 04:37:15 +0000106- Fixed contextlib.nested to cope with exceptions being raised and
107 caught inside exit handlers.
108
Greg Wardab05edc2006-04-23 03:47:58 +0000109- Updated optparse module to Optik 1.5.1 (allow numeric constants in
110 hex, octal, or binary; add ``append_const`` action; keep going if
111 gettext cannot be imported; added ``OptionParser.destroy()`` method;
112 added ``epilog`` for better help generation).
113
Tim Peters21fbd572006-04-21 21:18:10 +0000114- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
115 called from a thread spawned as a side effect of importing a module.
116
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000117- The pydoc module now supports documenting packages contained in
118 .zip or .egg files.
119
120- The pkgutil module now has several new utility functions, such
121 as ``walk_packages()`` to support working with packages that are either
122 in the filesystem or zip files.
123
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000124- The mailbox module can now modify and delete messages from
125 mailboxes, in addition to simply reading them. Thanks to Gregory
126 K. Johnson for writing the code, and to the 2005 Google Summer of
127 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000128
Tim Petersc7605f22006-04-17 21:12:33 +0000129- The ``__del__`` method of class ``local`` in module ``_threading_local``
130 returned before accomplishing any of its intended cleanup.
131
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000132- Patch #790710: Add breakpoint command lists in pdb.
133
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000134- Patch #1063914: Add Tkinter.Misc.clipboard_get().
135
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000136- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
137
Anthony Baxtere29002c2006-04-12 12:07:31 +0000138- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
139 Windows. Bug #1469163.
140
Phillip J. Eby47032112006-04-11 01:07:43 +0000141- The warnings, linecache, inspect, traceback, site, and doctest modules
142 were updated to work correctly with modules imported from zipfiles or
143 via other PEP 302 __loader__ objects.
144
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000145- Patch #1467770: Reduce usage of subprocess._active to processes which
146 the application hasn't waited on.
147
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000148- Patch #1462222: Fix Tix.Grid.
149
Neal Norwitza31bf182006-04-09 03:35:43 +0000150- Fix exception when doing glob.glob('anything*/')
151
Skip Montanaro262fb922006-04-21 02:31:07 +0000152- The pstats.Stats class accepts an optional stream keyword argument to
153 direct output to an alternate file-like object.
154

156-----
157
Martin v. Löwisb75d43d2006-04-29 12:37:25 +0000158- Patch #1471883: Add --enable-universalsdk.
159
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000160- The Makefile now has a reindent target, which runs reindent.py on
161 the library.
162
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000163- Patch #1470875: Building Python with MS Free Compiler
164
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000165- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000166
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000167- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
168 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000169 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000170 CXX from --with-cxx-main, see description in README.
171
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000172- Patch #1429775: Link extension modules with the shared libpython.
173
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000174- Fixed a libffi build problem on MIPS systems.

179Tests
180-----
181
Nick Coghlanda2268f2006-04-24 04:37:15 +0000182- test_contextlib now checks contextlib.nested can cope with exceptions
183 being raised and caught inside exit handlers.
184
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000185- test_cmd_line now checks operation of the -m and -c command switches
186
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000187- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
188 it separately and by hand. It also wasn't cleaning up its changes to
189 the current Decimal context.
190
Thomas Woutersabd08882006-04-26 15:53:30 +0000191- regrtest.py now has a -M option to run tests that test the new limits of
192 containers, on 64-bit architectures. Running these tests is only sensible
193 on 64-bit machines with more than two gigabytes of memory. The argument
194 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000202Documentation
203-------------
204
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000205- PEP 343: Added Context Types section to the library reference
206 and attempted to bring other PEP 343 related documentation into
207 line with the implementation and/or python-dev discussions.
208
Tim Peters8dc73d22006-04-24 02:03:16 +0000209- Bug #1337990: clarified that ``doctest`` does not support examples
210 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000213What's New in Python 2.5 alpha 1?
214=================================
215
Anthony Baxterebed3f62006-04-03 15:03:44 +0000216*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000217
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000218Core and builtins
219-----------------
220
Nick Coghlan43832302006-04-23 17:04:07 +0000221- PEP 338: -m command line switch now delegates to runpy.run_module
222 allowing it to support modules in packages and zipfiles
223
Martin v. Löwisc661b882006-04-20 04:54:23 +0000224- On Windows, .DLL is not an accepted file name extension for
225 extension modules anymore; extensions are only found if they
226 end in .PYD.
227
Martin v. Löwisea62d252006-04-03 10:56:49 +0000228- Bug #1421664: sys.stderr.encoding is now set to the same value as
229 sys.stdout.encoding.
230
Neal Norwitz92e212f2006-04-03 04:48:37 +0000231- __import__ accepts keyword arguments.
232
Georg Brandlccadf842006-03-31 18:54:53 +0000233- Patch #1460496: round() now accepts keyword arguments.
234
Anthony Baxter262c00a2006-03-30 10:53:17 +0000235- Fixed bug #1459029 - unicode reprs were double-escaped.
236
Hye-Shik Changd478f342006-03-23 12:32:36 +0000237- Patch #1396919: The system scope threads are reenabled on FreeBSD
238 5.4 and later versions.
239
Neal Norwitze98ccf62006-03-23 05:39:47 +0000240- Bug #1115379: Compiling a Unicode string with an encoding declaration
241 now gives a SyntaxError.
242
Georg Brandlabd1ff82006-03-18 07:59:59 +0000243- Previously, Python code had no easy way to access the contents of a
244 cell object. Now, a ``cell_contents`` attribute has been added
245 (closes patch #1170323).
246
Tim Peterscf79aac2006-03-16 01:14:46 +0000247- Patch #1123430: Python's small-object allocator now returns an arena to
248 the system ``free()`` when all memory within an arena becomes unused
249 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
250 freed. Some applications will see a drop in virtual memory size now,
251 especially long-running applications that, from time to time, temporarily
252 use a large number of small objects. Note that when Python returns an
253 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000254 platform C library will in turn return that memory to the operating system.
255 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000256 appears to be effective at least on Microsoft C and gcc-based systems.
257 Thanks to Evan Jones for hard work and patience.
258
Georg Brandl533ff6f2006-03-08 18:09:27 +0000259- Patch #1434038: property() now uses the getter's docstring if there is
260 no "doc" argument given. This makes it possible to legitimately use
261 property() as a decorator to produce a read-only property.
262
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000263- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
264 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
265 of requiring an int or long in slicing and a few other contexts, enabling
266 other objects (e.g. Numeric Python's integers) to be used as slice indices.
267
Neal Norwitz995acdf2006-03-07 05:01:00 +0000268- Fixed various bugs reported by Coverity's Prevent tool.
269
Brett Cannonbf364092006-03-01 04:25:17 +0000270- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
271 new exception base class, BaseException, which has a new message attribute.
272 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
273 Raising a string exception now raises a DeprecationWarning.
274
Thomas Woutersfb609f42006-02-28 16:37:25 +0000275- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
276 explicitly relative, using 'from .module import name' to mean 'from the same
277 package as this module is in. Imports without dots still default to the
278 old relative-then-absolute, unless 'from __future__ import
279 absolute_import' is used.
280
Brett Cannona7446e32006-02-27 23:39:10 +0000281- Properly check if 'warnings' raises an exception (usually when a filter set
282 to "error" is triggered) when raising a warning for raising string
283 exceptions.
284
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000285- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000286 The name was removed from Include/code.h.
287
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000288- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000289
Guido van Rossum1968ad32006-02-25 22:38:04 +0000290- Patch 1433928:
291 - The copy module now "copies" function objects (as atomic objects).
292 - dict.__getitem__ now looks for a __missing__ hook before raising
293 KeyError.
294
Tim Peters84ef21c2006-02-28 20:39:06 +0000295- PEP 343: with statement implemented. Needs ``from __future__ import
296 with_statement``. Use of 'with' as a variable will generate a warning.
297 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000298 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000299 The following objects have __context__ methods:
300 - The built-in file type.
301 - The thread.LockType type.
302 - The following types defined by the threading module:
303 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
304 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000305
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000306- Fix the encodings package codec search function to only search
307 inside its own package. Fixes problem reported in patch #1433198.
308
309 Note: Codec packages should implement and register their own
310 codec search function. PEP 100 has the details.
311
Martin v. Löwis18e16552006-02-15 17:27:45 +0000312- PEP 353: Using ssize_t as the index type.
313
Neal Norwitzfc76d632006-01-10 06:03:13 +0000314- Patch #1400181, fix unicode string formatting to not use the locale.
315 This is how string objects work. u'%f' could use , instead of .
316 for the decimal point. Now both strings and unicode always use periods.
317
Neal Norwitz671b9e32006-01-09 07:07:12 +0000318- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
319 configure would break checking curses.h.
320
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000321- Bug #959576: The pwd module is now builtin. This allows Python to be
322 built on UNIX platforms without $HOME set.
323
Neal Norwitzc10978f2005-12-19 06:07:16 +0000324- Bug #1072182, fix some potential problems if characters are signed.
325
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000326- Bug #889500, fix line number on SyntaxWarning for global declarations.
327
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000328- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
329
Neal Norwitze7214a12005-12-18 05:03:17 +0000330- Support for converting hex strings to floats no longer works.
331 This was not portable. float('0x3') now raises a ValueError.
332
Barry Warsaw2a38a862005-12-18 01:27:35 +0000333- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000334 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000335 is now displayed in interactive prompt banner.
336
Georg Brandlfa166682005-12-17 21:45:17 +0000337- Implementation of PEP 341 - Unification of try/except and try/finally.
338 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000339 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000340
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000341- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
342 now encodes backslash correctly.
343
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000344- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
345
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000346- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000347 and long longs.
348
Neal Norwitz67715f02005-11-09 06:59:35 +0000349- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000350 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000351 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000352
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000353- Replaced most Unicode charmap codecs with new ones using the
354 new Unicode translate string feature in the builtin charmap
355 codec; the codecs were created from the mapping tables available
356 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
357 encodings now include a mapping for the Apple logo)
358
Tim Peterse3547fd2005-12-16 23:13:57 +0000359- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000360
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000361- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000362
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000363- A new AST parser implementation was completed. The abstract
364 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000365 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000366
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000367- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000368 The following code now raises a SyntaxError: foo(a = i for i in range(10))
369
Neal Norwitz708e51a2005-10-03 04:48:15 +0000370- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
371
Neal Norwitz11bd1192005-10-03 00:54:56 +0000372- SF Bug #887946: fix segfault when redirecting stdin from a directory.
373 Provide a warning when a directory is passed on the command line.
374
Neal Norwitz40d37812005-10-02 01:48:49 +0000375- Fix segfault with invalid coding.
376
377- SF bug #772896: unknown encoding results in MemoryError.
378
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000379- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000380 supported a __len__() method which evaluated to False when the iterator
381 was empty.
382
Guido van Rossum630db602005-09-20 18:49:54 +0000383- On 64-bit platforms, when __len__() returns a value that cannot be
384 represented as a C int, raise OverflowError.
385
Skip Montanarof8948ca2005-09-19 03:54:46 +0000386- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000387 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000388
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000389- SF bug #893549: parsing keyword arguments was broken with a few format
390 codes.
391
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000392- Changes donated by Elemental Security to make it work on AIX 5.3
393 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
394 bug #105470: test_pwd fails on 64bit system (Opteron).
395
Guido van Rossum539c6622005-09-14 17:49:54 +0000396- Changes donated by Elemental Security to make it work on HP-UX 11 on
397 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
398
Georg Brandl4550b8d2005-08-26 06:43:52 +0000399- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000400 (fixes bug #1119418).
401
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000402- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
403
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000404- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
405 exceptions that cause a function to exit.
406
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000407- The implementation of set() and frozenset() was revised to use its
408 own internal data structure. Memory consumption is reduced by 1/3
409 and there are modest speed-ups as well. The API is unchanged.
410
Tim Petersde7990b2005-07-17 23:45:23 +0000411- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
412
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000413- SF bug #1229429: PyObject_CallMethod failed to decrement some
414 reference counts in some error exit cases.
415
Tim Petersecc6e6a2005-07-10 22:30:55 +0000416- SF bug #1185883: Python's small-object memory allocator took over
417 a block managed by the platform C library whenever a realloc specified
418 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000419 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000420 portable way to copy data from the C-managed block into Python's
421 small-object space without risking a memory fault. Python's small-object
422 realloc now leaves such blocks under the control of the platform C
423 realloc.
424
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000425- SF bug #1232517: An overflow error was not detected properly when
426 attempting to convert a large float to an int in os.utime().
427
Raymond Hettinger3296e692005-06-29 23:29:56 +0000428- SF bug #1224347: hex longs now print with lowercase letters just
429 like their int counterparts.
430
Michael W. Hudson188d4362005-06-20 16:52:57 +0000431- SF bug #1163563: the original fix for bug #1010677 ("thread Module
432 Breaks PyGILState_Ensure()") broke badly in the case of multiple
433 interpreter states; back out that fix and do a better job (see
434 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
435 for a longer write-up of the problem).
436
Michael W. Hudsondf888462005-06-03 14:41:55 +0000437- SF patch #1180995: marshal now uses a binary format by default when
438 serializing floats.
439
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000440- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
441 the routines that promise to produce IEEE 754 binary representations
442 of floats now simply copy bytes around.
443
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000444- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
445 278.
446
Brett Cannonc3647ac2005-04-26 03:45:26 +0000447- patch #1109424: int, long, float, complex, and unicode now check for the
448 proper magic slot for type conversions when subclassed. Previously the
449 magic slot was ignored during conversion. Semantics now match the way
450 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000451 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000452 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000453 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000454
Barry Warsawc8d907c2005-04-19 23:43:40 +0000455- Descriptors defined in C with a PyGetSetDef structure, where the setter is
456 NULL, now raise an AttributeError when attempting to set or delete the
457 attribute. Previously a TypeError was raised, but this was inconsistent
458 with the equivalent pure-Python implementation.
459
Michael W. Hudson774479c2005-04-18 08:46:17 +0000460- It is now safe to call PyGILState_Release() before
461 PyEval_InitThreads() (note that if there is reason to believe there
462 are multiple threads around you still must call PyEval_InitThreads()
463 before using the Python API; this fix is for extension modules that
464 have no way of knowing if Python is multi-threaded yet).
465
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000466- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
467 disabled caused a crash.
468
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000469- Bug #1165306: instancemethod_new allowed the creation of a method
470 with im_class == im_self == NULL, which caused a crash when called.
471
Tim Petersecc6e6a2005-07-10 22:30:55 +0000472- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000473 fixes the crash seen in bug #1165761
474
Raymond Hettinger96229b12005-03-11 06:49:40 +0000475- Added two new builtins, any() and all().
476
Brett Cannon409d8f22005-03-05 06:47:57 +0000477- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000478 (e.g., ``class C(): pass`` is no longer a syntax error).
479 Patch #1176012 added support to the 'parser' module and 'compiler' package
480 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000481
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000482- Patch #1115086: Support PY_LONGLONG in structmember.
483
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000484- Bug #1155938: new style classes did not check that __init__() was
485 returning None.
486
Tim Petersecc6e6a2005-07-10 22:30:55 +0000487- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000488 ('\') with a specific error message.
489
Martin v. Löwisff232d72005-03-03 09:24:38 +0000490- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
491
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000492- Bug #1124295: the __name__ attribute of file objects was
493 inadvertently made inaccessible in restricted mode.
494
Tim Petersecc6e6a2005-07-10 22:30:55 +0000495- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000496 an ferror() call.
497
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000498- min() and max() now support key= arguments with the same meaning as in
499 list.sort().
500
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000501- The peephole optimizer now performs simple constant folding in expressions:
502 (2+3) --> (5).
503
Raymond Hettingera422c342005-01-11 03:03:27 +0000504- set and frozenset objects can now be marshalled. SF #1098985.
505
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000506- Bug #1077106: Poor argument checking could cause memory corruption
507 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000508
Jeremy Hyltonab630502005-02-04 18:44:06 +0000509- The parser did not complain about future statements in illegal
510 positions. It once again reports a syntax error if a future
511 statement occurs after anything other than a doc string.
512
Neil Schemenauercf52c072005-08-12 17:34:58 +0000513- Change the %s format specifier for str objects so that it returns a
514 unicode instance if the argument is not an instance of basestring and
515 calling __str__ on the argument returns a unicode instance.
516
Tim Petersf4e69282006-02-27 17:15:31 +0000517- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
518 current thread state when the auto-GIL-state machinery knows about
519 it (since the thread state is being deleted, continuing to remember it
520 can't help, but can hurt if another thread happens to get created with
521 the same thread id).
522
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000523Extension Modules
524-----------------
525
Georg Brandl43f08a82006-03-31 18:01:16 +0000526- Patch #1380952: fix SSL objects timing out on consecutive read()s
527
Neal Norwitz05a45592006-03-20 06:30:08 +0000528- Patch #1309579: wait3 and wait4 were added to the posix module.
529
Anthony Baxterfa869072006-03-20 05:21:58 +0000530- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
531 In addition, the existing ulaw code was updated.
532
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000533- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000534 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000535
Neal Norwitz10be10c2006-03-16 06:50:13 +0000536- Everything under lib-old was removed. This includes the following modules:
537 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000538 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000539 util, whatsound, whrandom, zmod
540
541- The following modules were removed: regsub, reconvert, regex, regex_syntax.
542
543- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000544 is deprecated. The undocumented re.engine variable no longer exists.
545
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000546- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
547 SS2 (single-shift 2) escape sequences correctly.
548
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000549- The unicodedata module was updated to the 4.1 version of the Unicode
550 database. The 3.2 version is still available as unicodedata.db_3_2_0
551 for applications that require this specific version (such as IDNA).
552
Neal Norwitzb62c4332006-03-04 18:35:47 +0000553- The timing module is no longer built by default. It was deprecated
554 in PEP 4 in Python 2.0 or earlier.
555
Guido van Rossum1968ad32006-02-25 22:38:04 +0000556- Patch 1433928: Added a new type, defaultdict, to the collections module.
557 This uses the new __missing__ hook behavior added to dict (see above).
558
Georg Brandldbd83392006-02-20 09:42:33 +0000559- Bug #854823: socketmodule now builds on Sun platforms even when
560 INET_ADDRSTRLEN is not defined.
561
Georg Brandlf4f44152006-02-18 22:29:33 +0000562- Patch #1393157: os.startfile() now has an optional argument to specify
563 a "command verb" to invoke on the file.
564
Neal Norwitz082b2df2006-02-07 07:04:46 +0000565- Bug #876637, prevent stack corruption when socket descriptor
566 is larger than FD_SETSIZE.
567
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000568- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
569 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
570 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
571
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000572- Patch #1422385: The nis module now supports access to domains other
573 than the system default domain.
574
Martin v. Löwis14694662006-02-03 12:54:16 +0000575- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
576 are reported, the limit on path name lengths is removed, and stat reports
577 WindowsError now (instead of OSError).
578

711-------
712
Nick Coghlan43832302006-04-23 17:04:07 +0000713- PEP 338: new module runpy defines a run_module function to support
714 executing modules which provide access to source code or a code object
715 via the PEP 302 import mechanisms.
716
Anthony Baxter93f5b932006-04-03 08:05:07 +0000717- The email module's parsedate_tz function now sets the daylight savings

Georg Brandl828fdef2006-04-01 08:59:03 +0000728 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000729 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000730 module will not be built.
731
Tim Petersc17976e2006-04-01 00:26:53 +0000732- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
733 aren't officially supported here, and trying to use them will probably
734 raise an exception some day. But dicts have been allowed, and "mostly
735 worked", so support for them won't go away without warning.
736
Georg Brandl338ef7d2006-03-31 18:42:16 +0000737- Bug #1445068: getpass.getpass() can now be given an explicit stream

755
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000756- email 4.0 package now integrated. This is largely the same as the email 3.0
757 package that was included in Python 2.3, except that PEP 8 module names are
758 now used (e.g. mail.message instead of email.Message). The MIME classes
759 have been moved to a subpackage (e.g. email.mime.text instead of
760 email.MIMEText). The old names are still supported for now. Several
761 deprecated Message methods have been removed and lots of bugs have been
762 fixed. More details can be found in the email package documentation.
763
Walter Dörwald40108c92006-03-27 08:15:44 +0000764- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
765 (a subclass of tuple) that provides incremental decoders and encoders
766 (a way to use stateful codecs without the stream API). Python functions
767 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
768 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
769 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000770
Walter Dörwald067db482006-03-15 22:17:27 +0000771- Patch #1359365: Calling next() on a closed StringIO.String object raises
772 a ValueError instead of a StopIteration now (like file and cString.String do).
773 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
774 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000775

854 expressed at the NIST Hash Function Workshop 10/31/05),
855 is that SHA-256 is a good choice for the time being, but
856 that research should continue, and other alternatives may
857 arise from this research. The larger SHA's also seem OK."

912 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000913 correct line numbers for decoding errors in source code.

952 Bug #1224621.
953
Raymond Hettinger68c04532005-06-10 11:05:19 +0000954- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000955 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000956 the generate_tokens() function now accepts a callable argument that
957 terminates by raising StopIteration.
958
Georg Brandl9166e1a2005-06-04 09:20:03 +0000959- Bug #1196315: fix weakref.WeakValueDictionary constructor.

967 class at all.
968
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000969- distutils.commands.upload was added to support uploading distribution

971
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000972- distutils.commands.register now encodes the data as UTF-8 before posting
973 them to PyPI.
974
Raymond Hettinger267b8682005-03-27 10:47:39 +0000975- decimal operator and comparison methods now return NotImplemented
976 instead of raising a TypeError when interacting with other types. This
977 allows other classes to implement __radd__ style methods and have them
978 work as expected.
979
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000980- Bug #1163325: Decimal infinities failed to hash. Attempting to
981 hash a NaN raised an InvalidOperation instead of a TypeError.
982
Tim Petersecc6e6a2005-07-10 22:30:55 +0000983- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1017
Guido van Rossumd0641422005-02-03 15:01:24 +00001018- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1019 disables recursive traversal through instance attributes, which can
1020 be exploited in various ways.
1021
Tim Peterse3547fd2005-12-16 23:13:57 +00001022- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001023 flags on the HTTP listening socket.
1024
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001025- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1026 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1027
Tim Peterse3547fd2005-12-16 23:13:57 +00001028- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001029 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1030
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001031- Bug #1110478: Revert os.environ.update to do putenv again.
1032
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001033- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1034
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001035- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1036
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001037- Enhancements to the csv module:
1038
1039 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001040 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001041 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001042 + Dialect parameter parsing has been re-implemented to improve error
1043 reporting.
1044 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1045 dictates.
1046 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001047 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001048 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001049 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1050 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001051 + reader now allows \r characters to be quoted (previously it only allowed
1052 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001053 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001054 + Dialect classes passed to the module are no longer instantiated by
1055 the module before being parsed (the former validation scheme required
1056 this, but the mechanism was unreliable).
1057 + The dialect registry now contains instances of the internal
1058 C-coded dialect type, rather than references to python objects.
1059 + the internal c-coded dialect type is now immutable.
1060 + register_dialect now accepts the same keyword dialect specifications
1061 as the reader and writer, allowing the user to register dialects
1062 without first creating a dialect class.
1063 + a configurable limit to the size of parsed fields has been added -
1064 previously, an unmatched quote character could result in the entire
1065 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001066 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001067 the parser field size limit (returning the former limit). The initial
1068 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001069 + A line_num attribute has been added to the reader object, which tracks
1070 the number of lines read from the source iterator. This is not
1071 the same as the number of records returned, as records can span
1072 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001073 + reader and writer objects were not being registered with the cyclic-GC.
1074 This has been fixed.
1075
Brett Cannone6539c42005-01-08 02:43:53 +00001076- _DummyThread objects in the threading module now delete self.__block that is
1077 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1078 lock primitives tend to be limited in number and thus should not be wasted on
1079 a _DummyThread object. Fixes bug #1089632.
1080
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001081- The imghdr module now detects Exif files.
1082
Raymond Hettinger6065d322004-12-20 23:51:53 +00001083- StringIO.truncate() now correctly adjusts the size attribute.
1084 (Bug #951915).
1085
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001086- locale.py now uses an updated locale alias table (built using
1087 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1088 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001089 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001090
Raymond Hettinger3557f422004-12-07 12:02:02 +00001091- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1092
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001093- the pickle module no longer accepts the deprecated None option in the
1094 args tuple returned by __reduce__().
1095
Brett Cannon84667c02004-12-07 03:25:18 +00001096- optparse now optionally imports gettext. This allows its use in setup.py.
1097
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001098- the pickle module no longer uses the deprecated bin parameter.
1099
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001100- the shelve module no longer uses the deprecated binary parameter.
1101
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001102- the pstats module no longer uses the deprecated ignore() method.
1103
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001104- the filecmp module no longer uses the deprecated use_statcache argument.
1105
Raymond Hettinger664347b2004-12-04 21:21:53 +00001106- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1107 extended or overridden by subclasses. Formerly, the subclassed method would
1108 be ignored by the rest of the module. (Bug #1078905).
1109
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001110- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001111 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001112
Walter Dörwald36733692004-12-22 12:50:50 +00001113- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1114 once when a size argument is given. This prevents a buffer overflow in the
1115 tokenizer with very long source lines.
1116
Barry Warsaw538561e2006-01-01 21:48:54 +00001117- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1118 immediately after creating the object, without any intervening
1119 ``.decompress()`` calls.

Skip Montanaro05885812005-01-16 20:48:27 +00001121- The reconvert.quote function can now emit triple-quoted strings. The
1122 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001123
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001124- ``UserString.MutableString`` now supports negative indices in
1125 ``__setitem__`` and ``__delitem__``
1126
Greg Ward40407942005-03-05 02:53:17 +00001127- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1128 correctly.
1129
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001130- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1131 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1132 character even if the user has passed a size parameter to get a proper
1133 line ending. Remove the special handling of a "\r\n" that has been split
1134 between two lines.
1135
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001136- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1137 about illegal code points. The codec now supports PEP 293 style error
1138 handlers.
1139
Walter Dörwald78a78b02005-09-01 12:04:29 +00001140- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001141 from the input stream, so that the output is a byte string in the correct
1142 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001143
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001144- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1145 considering it exactly like a '*'.
1146
Walter Dörwald007f8df2005-10-09 19:42:27 +00001147- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1148 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001149
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001150- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1151
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001152- Patch #1413711: Certain patterns of differences were making difflib
1153 touch the recursion limit.
1154
Walter Dörwald58917a62006-03-31 15:26:22 +00001155- Bug #947906: An object oriented interface has been added to the calendar
1156 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001157 called as a script (e.g. via ``python -mcalendar``). Localized month and
1158 weekday names can be ouput (even if an exotic encoding is used) using
1159 special classes that use unicode.

1162-----
1163
Neal Norwitz602d3392006-03-31 08:21:40 +00001164- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1165 by using -mieee gcc option.
1166

1168
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001169- Build support for Win64-AMD64 was added.
1170
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001171- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1172
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001173- Patch #881820: look for openpty and forkpty also in libbsd.
1174
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001175- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1176 The zlib module is now builtin on Windows.
1177
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001178- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1179
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001180- Bug #1189330: configure did not correctly determine the necessary
1181 value of LINKCC if python was built with GCC 4.0.
1182
Trent Mick8321b422005-07-26 02:29:21 +00001183- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1184 vulnerability in zlib 1.2.1 and 1.2.2.
1185
Brett Cannon08cd5982005-04-24 22:26:38 +00001186- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1187 flags that change binary compatibility. Changes were also made to
1188 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001189 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001190
Bob Ippolitoed233462005-03-29 13:47:59 +00001191- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1192 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1193 no longer exists). This configure patch makes things right.
1194
Martin v. Löwise2713be2005-03-08 15:03:08 +00001195- Bug #1158607: Build with --disable-unicode again.
1196
Brett Cannon46d96232005-02-16 00:07:19 +00001197- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1198 defined. Discovered as a result of not being able to build on OS X.
1199
Brett Cannon516592f2004-12-07 00:42:59 +00001200- setup.py now uses the directories specified in LDFLAGS using the -L option
1201 and in CPPFLAGS using the -I option for adding library and include
1202 directories, respectively, for compiling extension modules against. This has
1203 led to the core being compiled using the values in CPPFLAGS. It also removes
1204 the need for the special-casing of both DarwinPorts and Fink for darwin since
1205 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1206 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1207 Fink, ``-I/opt/local/include`` for DarwinPorts).
1208
Brett Cannon43802422005-02-10 20:48:03 +00001209- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1210 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1211 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1212 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001214C API
1215-----
1216
Tim Petersc9d78aa2006-03-26 23:27:58 +00001217- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1218 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1219 is obtained via the ``PyObject_`` family, it must be released via the
1220 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1221 always been officially true, but when Python's small-object allocator was
1222 introduced, an attempt was made to cater to a few extension modules
1223 discovered at the time that obtained memory via ``PyObject_New`` but
1224 released it via ``PyMem_DEL``. It's years later, and if such code still
1225 exists it will fail now (probably with segfaults, but calling wrong
1226 low-level memory management functions can yield many symptoms).
1227
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001228- Added a C API for set and frozenset objects.
1229
Raymond Hettinger66517482004-12-03 11:45:13 +00001230- Removed PyRange_New().
1231
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001232- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1233 mapping argument now. This string is used as a mapping table. Byte values
1234 greater than the length of the string and 0xFFFE are treated as undefined
1235 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001241- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001242
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001243- Patch #1276356: New resource "urlfetch" is implemented. This enables
1244 even impatient people to run tests that require remote files.
