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
Martin v. Löwis77736712006-05-04 05:51:03 +000015- Patch #1475845: Raise IndentationError for unexpected indent.
16
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000017- Patch #1479181: split open() and file() from being aliases for each other.
18
Thomas Heller1b046642006-04-18 18:51:06 +000019- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
20 by converting these apis from macros into exported functions again:
21
22 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
23 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
24 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
25 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
26 PyRun_String Py_CompileString
27
Martin v. Löwis45294a92006-04-18 06:24:08 +000028- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
29
Martin v. Löwis19ab6c92006-04-16 18:55:50 +000030- All uses of PyStructSequence_InitType have been changed to initialize
31 the type objects only once, even if the interpreter is initialized
32 multiple times.
33
Neal Norwitz61546162006-04-14 05:20:28 +000034- Bug #1454485, array.array('u') could crash the interpreter. This was
35 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
36 to unicode when it didn't make sense. 'u#' now requires a unicode string.
37
38- Py_UNICODE is unsigned. It was always documented as unsigned, but
39 due to a bug had a signed value in previous versions.
40
Tim Peters3a5e8b12006-04-11 01:44:07 +000041- Patch #837242: ``id()`` of any Python object always gives a positive
42 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
43 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000044 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000045 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000046
Tim Peters3a5e8b12006-04-11 01:44:07 +000047 def __hash__(self):
48 return id(self) # WRONG
49
50 because a hash result must be a (short) Python int but it was always
51 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000052 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000053 was always usable as a hash value before this patch. That's no longer
54 necessarily so.
55
56- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000057 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000058 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000059 #1454844)
60
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000061- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
62 involving generators that have paused outside of any ``try`` or ``with``
63 blocks. (In 2.5a1, a paused generator that was part of a reference
64 cycle could not be garbage collected, regardless of whether it was
65 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +000066
Anthony Baxter51bcb682006-04-05 14:51:42 +000067Extension Modules
68-----------------
69
Martin v. Löwisd4e3bb32006-05-06 16:32:54 +000070- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
71 As a result, these functions now raise WindowsError instead of OSError.
Martin v. Löwis8e0d4942006-05-04 10:08:42 +000072
Martin v. Löwis86725192006-05-01 06:28:01 +000073- Calling Tk_Init twice is refused if the first call failed as that
74 may deadlock.
75
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000076- Patch #1191065: Fix preprocessor problems on systems where recvfrom
77 is a macro.
78
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000079- Bug #1467952: os.listdir() now correctly raises an error if readdir()
80 fails with an error condition.
81
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000082- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
83
84- Bug #1117761: bsddb.*open() no longer raises an exception when using
85 the cachesize parameter.
86
87- Bug #1149413: bsddb.*open() no longer raises an exception when using
88 a temporary db (file=None) with the 'n' flag to truncate on open.
89
90- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
91 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +000092
Armin Rigoa9017c32006-04-19 11:50:27 +000093- Patch #1062014: AF_UNIX sockets under Linux have a special
94 abstract namespace that is now fully supported.
95
Anthony Baxter51bcb682006-04-05 14:51:42 +000096Library
97-------
98
Georg Brandl1bb62302006-05-03 18:18:32 +000099- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
100 package.
101
Georg Brandl3583cff2006-04-30 18:14:54 +0000102- Patch #1472854: make the rlcompleter.Completer class usable on non-
103 UNIX platforms.
104
Georg Brandlfa42bd72006-04-30 07:06:11 +0000105- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
106
Tim Peters711bf302006-04-25 03:31:36 +0000107- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
108 a doctest to be skipped (the code is not run, and the expected output
109 or exception is ignored).
110
Nick Coghlanda2268f2006-04-24 04:37:15 +0000111- Fixed contextlib.nested to cope with exceptions being raised and
112 caught inside exit handlers.
113
Greg Wardab05edc2006-04-23 03:47:58 +0000114- Updated optparse module to Optik 1.5.1 (allow numeric constants in
115 hex, octal, or binary; add ``append_const`` action; keep going if
116 gettext cannot be imported; added ``OptionParser.destroy()`` method;
117 added ``epilog`` for better help generation).
118
Tim Peters21fbd572006-04-21 21:18:10 +0000119- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
120 called from a thread spawned as a side effect of importing a module.
121
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000122- The pydoc module now supports documenting packages contained in
123 .zip or .egg files.
124
125- The pkgutil module now has several new utility functions, such
126 as ``walk_packages()`` to support working with packages that are either
127 in the filesystem or zip files.
128
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000129- The mailbox module can now modify and delete messages from
130 mailboxes, in addition to simply reading them. Thanks to Gregory
131 K. Johnson for writing the code, and to the 2005 Google Summer of
132 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000133
Tim Petersc7605f22006-04-17 21:12:33 +0000134- The ``__del__`` method of class ``local`` in module ``_threading_local``
135 returned before accomplishing any of its intended cleanup.
136
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000137- Patch #790710: Add breakpoint command lists in pdb.
138
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000139- Patch #1063914: Add Tkinter.Misc.clipboard_get().
140
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000141- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
142
Anthony Baxtere29002c2006-04-12 12:07:31 +0000143- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
144 Windows. Bug #1469163.
145
Phillip J. Eby47032112006-04-11 01:07:43 +0000146- The warnings, linecache, inspect, traceback, site, and doctest modules
147 were updated to work correctly with modules imported from zipfiles or
148 via other PEP 302 __loader__ objects.
149
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000150- Patch #1467770: Reduce usage of subprocess._active to processes which
151 the application hasn't waited on.
152
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000153- Patch #1462222: Fix Tix.Grid.
154
Neal Norwitza31bf182006-04-09 03:35:43 +0000155- Fix exception when doing glob.glob('anything*/')
156
Skip Montanaro262fb922006-04-21 02:31:07 +0000157- The pstats.Stats class accepts an optional stream keyword argument to
158 direct output to an alternate file-like object.

161-----
162
Martin v. Löwisb75d43d2006-04-29 12:37:25 +0000163- Patch #1471883: Add --enable-universalsdk.
164
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000165- The Makefile now has a reindent target, which runs reindent.py on
166 the library.
167
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000168- Patch #1470875: Building Python with MS Free Compiler
169
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000170- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000171
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000172- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
173 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000174 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000175 CXX from --with-cxx-main, see description in README.
176
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000177- Patch #1429775: Link extension modules with the shared libpython.
178
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000179- Fixed a libffi build problem on MIPS systems.

184Tests
185-----
186
Nick Coghlanda2268f2006-04-24 04:37:15 +0000187- test_contextlib now checks contextlib.nested can cope with exceptions
188 being raised and caught inside exit handlers.
189
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000190- test_cmd_line now checks operation of the -m and -c command switches
191
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000192- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
193 it separately and by hand. It also wasn't cleaning up its changes to
194 the current Decimal context.
195
Thomas Woutersabd08882006-04-26 15:53:30 +0000196- regrtest.py now has a -M option to run tests that test the new limits of
197 containers, on 64-bit architectures. Running these tests is only sensible
198 on 64-bit machines with more than two gigabytes of memory. The argument
199 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000207Documentation
208-------------
209
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000210- PEP 343: Added Context Types section to the library reference
211 and attempted to bring other PEP 343 related documentation into
212 line with the implementation and/or python-dev discussions.
213
Tim Peters8dc73d22006-04-24 02:03:16 +0000214- Bug #1337990: clarified that ``doctest`` does not support examples
215 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000218What's New in Python 2.5 alpha 1?
219=================================
220
Anthony Baxterebed3f62006-04-03 15:03:44 +0000221*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000222
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000223Core and builtins
224-----------------
225
Nick Coghlan43832302006-04-23 17:04:07 +0000226- PEP 338: -m command line switch now delegates to runpy.run_module
227 allowing it to support modules in packages and zipfiles
228
Martin v. Löwisc661b882006-04-20 04:54:23 +0000229- On Windows, .DLL is not an accepted file name extension for
230 extension modules anymore; extensions are only found if they
231 end in .PYD.
232
Martin v. Löwisea62d252006-04-03 10:56:49 +0000233- Bug #1421664: sys.stderr.encoding is now set to the same value as
234 sys.stdout.encoding.
235
Neal Norwitz92e212f2006-04-03 04:48:37 +0000236- __import__ accepts keyword arguments.
237
Georg Brandlccadf842006-03-31 18:54:53 +0000238- Patch #1460496: round() now accepts keyword arguments.
239
Anthony Baxter262c00a2006-03-30 10:53:17 +0000240- Fixed bug #1459029 - unicode reprs were double-escaped.
241
Hye-Shik Changd478f342006-03-23 12:32:36 +0000242- Patch #1396919: The system scope threads are reenabled on FreeBSD
243 5.4 and later versions.
244
Neal Norwitze98ccf62006-03-23 05:39:47 +0000245- Bug #1115379: Compiling a Unicode string with an encoding declaration
246 now gives a SyntaxError.
247
Georg Brandlabd1ff82006-03-18 07:59:59 +0000248- Previously, Python code had no easy way to access the contents of a
249 cell object. Now, a ``cell_contents`` attribute has been added
250 (closes patch #1170323).
251
Tim Peterscf79aac2006-03-16 01:14:46 +0000252- Patch #1123430: Python's small-object allocator now returns an arena to
253 the system ``free()`` when all memory within an arena becomes unused
254 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
255 freed. Some applications will see a drop in virtual memory size now,
256 especially long-running applications that, from time to time, temporarily
257 use a large number of small objects. Note that when Python returns an
258 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000259 platform C library will in turn return that memory to the operating system.
260 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000261 appears to be effective at least on Microsoft C and gcc-based systems.
262 Thanks to Evan Jones for hard work and patience.
263
Georg Brandl533ff6f2006-03-08 18:09:27 +0000264- Patch #1434038: property() now uses the getter's docstring if there is
265 no "doc" argument given. This makes it possible to legitimately use
266 property() as a decorator to produce a read-only property.
267
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000268- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
269 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
270 of requiring an int or long in slicing and a few other contexts, enabling
271 other objects (e.g. Numeric Python's integers) to be used as slice indices.
272
Neal Norwitz995acdf2006-03-07 05:01:00 +0000273- Fixed various bugs reported by Coverity's Prevent tool.
274
Brett Cannonbf364092006-03-01 04:25:17 +0000275- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
276 new exception base class, BaseException, which has a new message attribute.
277 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
278 Raising a string exception now raises a DeprecationWarning.
279
Thomas Woutersfb609f42006-02-28 16:37:25 +0000280- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
281 explicitly relative, using 'from .module import name' to mean 'from the same
282 package as this module is in. Imports without dots still default to the
283 old relative-then-absolute, unless 'from __future__ import
284 absolute_import' is used.
285
Brett Cannona7446e32006-02-27 23:39:10 +0000286- Properly check if 'warnings' raises an exception (usually when a filter set
287 to "error" is triggered) when raising a warning for raising string
288 exceptions.
289
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000290- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000291 The name was removed from Include/code.h.
292
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000293- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000294
Guido van Rossum1968ad32006-02-25 22:38:04 +0000295- Patch 1433928:
296 - The copy module now "copies" function objects (as atomic objects).
297 - dict.__getitem__ now looks for a __missing__ hook before raising
298 KeyError.
299
Tim Peters84ef21c2006-02-28 20:39:06 +0000300- PEP 343: with statement implemented. Needs ``from __future__ import
301 with_statement``. Use of 'with' as a variable will generate a warning.
302 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000303 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000304 The following objects have __context__ methods:
305 - The built-in file type.
306 - The thread.LockType type.
307 - The following types defined by the threading module:

Guido van Rossumc2e20742006-02-27 22:32:47 +0000310
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000311- Fix the encodings package codec search function to only search
312 inside its own package. Fixes problem reported in patch #1433198.
313
314 Note: Codec packages should implement and register their own
315 codec search function. PEP 100 has the details.
316
Martin v. Löwis18e16552006-02-15 17:27:45 +0000317- PEP 353: Using ssize_t as the index type.
318
Neal Norwitzfc76d632006-01-10 06:03:13 +0000319- Patch #1400181, fix unicode string formatting to not use the locale.
320 This is how string objects work. u'%f' could use , instead of .
321 for the decimal point. Now both strings and unicode always use periods.
322
Neal Norwitz671b9e32006-01-09 07:07:12 +0000323- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
324 configure would break checking curses.h.
325
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000326- Bug #959576: The pwd module is now builtin. This allows Python to be
327 built on UNIX platforms without $HOME set.
328
Neal Norwitzc10978f2005-12-19 06:07:16 +0000329- Bug #1072182, fix some potential problems if characters are signed.
330
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000331- Bug #889500, fix line number on SyntaxWarning for global declarations.
332
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000333- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
334
Neal Norwitze7214a12005-12-18 05:03:17 +0000335- Support for converting hex strings to floats no longer works.
336 This was not portable. float('0x3') now raises a ValueError.
337
Barry Warsaw2a38a862005-12-18 01:27:35 +0000338- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000339 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000340 is now displayed in interactive prompt banner.
341
Georg Brandlfa166682005-12-17 21:45:17 +0000342- Implementation of PEP 341 - Unification of try/except and try/finally.
343 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000344 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000345
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000346- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
347 now encodes backslash correctly.
348
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000349- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
350
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000351- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000352 and long longs.
353
Neal Norwitz67715f02005-11-09 06:59:35 +0000354- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000355 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000356 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000357
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000358- Replaced most Unicode charmap codecs with new ones using the
359 new Unicode translate string feature in the builtin charmap
360 codec; the codecs were created from the mapping tables available
361 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
362 encodings now include a mapping for the Apple logo)
363
Tim Peterse3547fd2005-12-16 23:13:57 +0000364- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000365
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000366- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000367
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000368- A new AST parser implementation was completed. The abstract
369 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000370 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000371
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000372- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000373 The following code now raises a SyntaxError: foo(a = i for i in range(10))
374
Neal Norwitz708e51a2005-10-03 04:48:15 +0000375- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
376
Neal Norwitz11bd1192005-10-03 00:54:56 +0000377- SF Bug #887946: fix segfault when redirecting stdin from a directory.
378 Provide a warning when a directory is passed on the command line.
379
Neal Norwitz40d37812005-10-02 01:48:49 +0000380- Fix segfault with invalid coding.
381
382- SF bug #772896: unknown encoding results in MemoryError.
383
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000384- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000385 supported a __len__() method which evaluated to False when the iterator
386 was empty.
387
Guido van Rossum630db602005-09-20 18:49:54 +0000388- On 64-bit platforms, when __len__() returns a value that cannot be
389 represented as a C int, raise OverflowError.
390
Skip Montanarof8948ca2005-09-19 03:54:46 +0000391- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000392 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000393
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000394- SF bug #893549: parsing keyword arguments was broken with a few format
395 codes.
396
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000397- Changes donated by Elemental Security to make it work on AIX 5.3
398 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
399 bug #105470: test_pwd fails on 64bit system (Opteron).
400
Guido van Rossum539c6622005-09-14 17:49:54 +0000401- Changes donated by Elemental Security to make it work on HP-UX 11 on
402 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
403
Georg Brandl4550b8d2005-08-26 06:43:52 +0000404- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000405 (fixes bug #1119418).
406
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000407- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
408
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000409- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
410 exceptions that cause a function to exit.
411
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000412- The implementation of set() and frozenset() was revised to use its
413 own internal data structure. Memory consumption is reduced by 1/3
414 and there are modest speed-ups as well. The API is unchanged.
415
Tim Petersde7990b2005-07-17 23:45:23 +0000416- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
417
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000418- SF bug #1229429: PyObject_CallMethod failed to decrement some
419 reference counts in some error exit cases.
420
Tim Petersecc6e6a2005-07-10 22:30:55 +0000421- SF bug #1185883: Python's small-object memory allocator took over
422 a block managed by the platform C library whenever a realloc specified
423 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000424 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000425 portable way to copy data from the C-managed block into Python's
426 small-object space without risking a memory fault. Python's small-object
427 realloc now leaves such blocks under the control of the platform C
428 realloc.
429
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000430- SF bug #1232517: An overflow error was not detected properly when
431 attempting to convert a large float to an int in os.utime().
432
Raymond Hettinger3296e692005-06-29 23:29:56 +0000433- SF bug #1224347: hex longs now print with lowercase letters just
434 like their int counterparts.
435
Michael W. Hudson188d4362005-06-20 16:52:57 +0000436- SF bug #1163563: the original fix for bug #1010677 ("thread Module
437 Breaks PyGILState_Ensure()") broke badly in the case of multiple
438 interpreter states; back out that fix and do a better job (see
439 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
440 for a longer write-up of the problem).
441
Michael W. Hudsondf888462005-06-03 14:41:55 +0000442- SF patch #1180995: marshal now uses a binary format by default when
443 serializing floats.
444
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000445- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
446 the routines that promise to produce IEEE 754 binary representations
447 of floats now simply copy bytes around.
448
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000449- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
450 278.
451
Brett Cannonc3647ac2005-04-26 03:45:26 +0000452- patch #1109424: int, long, float, complex, and unicode now check for the
453 proper magic slot for type conversions when subclassed. Previously the
454 magic slot was ignored during conversion. Semantics now match the way
455 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000456 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000457 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000458 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000459
Barry Warsawc8d907c2005-04-19 23:43:40 +0000460- Descriptors defined in C with a PyGetSetDef structure, where the setter is
461 NULL, now raise an AttributeError when attempting to set or delete the
462 attribute. Previously a TypeError was raised, but this was inconsistent
463 with the equivalent pure-Python implementation.
464
Michael W. Hudson774479c2005-04-18 08:46:17 +0000465- It is now safe to call PyGILState_Release() before
466 PyEval_InitThreads() (note that if there is reason to believe there
467 are multiple threads around you still must call PyEval_InitThreads()
468 before using the Python API; this fix is for extension modules that
469 have no way of knowing if Python is multi-threaded yet).
470
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000471- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
472 disabled caused a crash.
473
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000474- Bug #1165306: instancemethod_new allowed the creation of a method
475 with im_class == im_self == NULL, which caused a crash when called.
476
Tim Petersecc6e6a2005-07-10 22:30:55 +0000477- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000478 fixes the crash seen in bug #1165761
479
Raymond Hettinger96229b12005-03-11 06:49:40 +0000480- Added two new builtins, any() and all().
481
Brett Cannon409d8f22005-03-05 06:47:57 +0000482- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000483 (e.g., ``class C(): pass`` is no longer a syntax error).
484 Patch #1176012 added support to the 'parser' module and 'compiler' package
485 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000486
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000487- Patch #1115086: Support PY_LONGLONG in structmember.
488
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000489- Bug #1155938: new style classes did not check that __init__() was
490 returning None.
491
Tim Petersecc6e6a2005-07-10 22:30:55 +0000492- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000493 ('\') with a specific error message.
494
Martin v. Löwisff232d72005-03-03 09:24:38 +0000495- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
496
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000497- Bug #1124295: the __name__ attribute of file objects was
498 inadvertently made inaccessible in restricted mode.
499
Tim Petersecc6e6a2005-07-10 22:30:55 +0000500- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000501 an ferror() call.
502
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000503- min() and max() now support key= arguments with the same meaning as in
504 list.sort().
505
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000506- The peephole optimizer now performs simple constant folding in expressions:
507 (2+3) --> (5).
508
Raymond Hettingera422c342005-01-11 03:03:27 +0000509- set and frozenset objects can now be marshalled. SF #1098985.
510
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000511- Bug #1077106: Poor argument checking could cause memory corruption
512 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000513
Jeremy Hyltonab630502005-02-04 18:44:06 +0000514- The parser did not complain about future statements in illegal
515 positions. It once again reports a syntax error if a future
516 statement occurs after anything other than a doc string.
517
Neil Schemenauercf52c072005-08-12 17:34:58 +0000518- Change the %s format specifier for str objects so that it returns a
519 unicode instance if the argument is not an instance of basestring and
520 calling __str__ on the argument returns a unicode instance.
521
Tim Petersf4e69282006-02-27 17:15:31 +0000522- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
523 current thread state when the auto-GIL-state machinery knows about
524 it (since the thread state is being deleted, continuing to remember it
525 can't help, but can hurt if another thread happens to get created with
526 the same thread id).
527
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000528Extension Modules
529-----------------
530
Georg Brandl43f08a82006-03-31 18:01:16 +0000531- Patch #1380952: fix SSL objects timing out on consecutive read()s
532
Neal Norwitz05a45592006-03-20 06:30:08 +0000533- Patch #1309579: wait3 and wait4 were added to the posix module.
534
Anthony Baxterfa869072006-03-20 05:21:58 +0000535- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
536 In addition, the existing ulaw code was updated.
537
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000538- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000539 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000540
Neal Norwitz10be10c2006-03-16 06:50:13 +0000541- Everything under lib-old was removed. This includes the following modules:
542 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000543 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000544 util, whatsound, whrandom, zmod
545
546- The following modules were removed: regsub, reconvert, regex, regex_syntax.
547
548- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000549 is deprecated. The undocumented re.engine variable no longer exists.
550
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000551- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
552 SS2 (single-shift 2) escape sequences correctly.
553
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000554- The unicodedata module was updated to the 4.1 version of the Unicode
555 database. The 3.2 version is still available as unicodedata.db_3_2_0
556 for applications that require this specific version (such as IDNA).
557
Neal Norwitzb62c4332006-03-04 18:35:47 +0000558- The timing module is no longer built by default. It was deprecated
559 in PEP 4 in Python 2.0 or earlier.
560
Guido van Rossum1968ad32006-02-25 22:38:04 +0000561- Patch 1433928: Added a new type, defaultdict, to the collections module.
562 This uses the new __missing__ hook behavior added to dict (see above).
563
Georg Brandldbd83392006-02-20 09:42:33 +0000564- Bug #854823: socketmodule now builds on Sun platforms even when
565 INET_ADDRSTRLEN is not defined.
566
Georg Brandlf4f44152006-02-18 22:29:33 +0000567- Patch #1393157: os.startfile() now has an optional argument to specify
568 a "command verb" to invoke on the file.
569
Neal Norwitz082b2df2006-02-07 07:04:46 +0000570- Bug #876637, prevent stack corruption when socket descriptor
571 is larger than FD_SETSIZE.
572
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000573- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
574 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
575 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

716-------
717
Nick Coghlan43832302006-04-23 17:04:07 +0000718- PEP 338: new module runpy defines a run_module function to support
719 executing modules which provide access to source code or a code object
720 via the PEP 302 import mechanisms.

Georg Brandl828fdef2006-04-01 08:59:03 +0000733 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000734 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000735 module will not be built.
736
Tim Petersc17976e2006-04-01 00:26:53 +0000737- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
738 aren't officially supported here, and trying to use them will probably
739 raise an exception some day. But dicts have been allowed, and "mostly
740 worked", so support for them won't go away without warning.
741
Georg Brandl338ef7d2006-03-31 18:42:16 +0000742- Bug #1445068: getpass.getpass() can now be given an explicit stream

760
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000761- email 4.0 package now integrated. This is largely the same as the email 3.0
762 package that was included in Python 2.3, except that PEP 8 module names are
763 now used (e.g. mail.message instead of email.Message). The MIME classes
764 have been moved to a subpackage (e.g. email.mime.text instead of
765 email.MIMEText). The old names are still supported for now. Several
766 deprecated Message methods have been removed and lots of bugs have been
767 fixed. More details can be found in the email package documentation.
768
Walter Dörwald40108c92006-03-27 08:15:44 +0000769- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
770 (a subclass of tuple) that provides incremental decoders and encoders
771 (a way to use stateful codecs without the stream API). Python functions
772 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
773 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
774 have been added.

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

Brett Cannon3cbd0382005-12-16 22:49:23 +0000852- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +0000853 SHA1, 224, 256, 384, and 512. Note that recent developments make the
854 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
855 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
856 Ronald L. Rivest offered this advice for Python:
857
858 "The consensus of researchers in this area (at least as
859 expressed at the NIST Hash Function Workshop 10/31/05),
860 is that SHA-256 is a good choice for the time being, but
861 that research should continue, and other alternatives may
862 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000863
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000864- Added a subset of Fredrik Lundh's ElementTree package. Available

917 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000918 correct line numbers for decoding errors in source code.

935 parameter, but uses the usual "kwargs=None".
936
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000937- textwrap now processes text chunks at O(n) speed instead of O(n**2).

957 Bug #1224621.
958
Raymond Hettinger68c04532005-06-10 11:05:19 +0000959- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000960 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000961 the generate_tokens() function now accepts a callable argument that
962 terminates by raising StopIteration.
963
Georg Brandl9166e1a2005-06-04 09:20:03 +0000964- Bug #1196315: fix weakref.WeakValueDictionary constructor.

978 them to PyPI.
979
Raymond Hettinger267b8682005-03-27 10:47:39 +0000980- decimal operator and comparison methods now return NotImplemented
981 instead of raising a TypeError when interacting with other types. This
982 allows other classes to implement __radd__ style methods and have them
983 work as expected.
984
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000985- Bug #1163325: Decimal infinities failed to hash. Attempting to
986 hash a NaN raised an InvalidOperation instead of a TypeError.
987
Tim Petersecc6e6a2005-07-10 22:30:55 +0000988- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1022
Guido van Rossumd0641422005-02-03 15:01:24 +00001023- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1024 disables recursive traversal through instance attributes, which can
1025 be exploited in various ways.
1026
Tim Peterse3547fd2005-12-16 23:13:57 +00001027- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001028 flags on the HTTP listening socket.
1029
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001030- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1031 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1032
Tim Peterse3547fd2005-12-16 23:13:57 +00001033- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001034 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1035

1037
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001038- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1039
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001040- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1041
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001042- Enhancements to the csv module:
1043
1044 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001045 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001046 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001047 + Dialect parameter parsing has been re-implemented to improve error
1048 reporting.
1049 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1050 dictates.
1051 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001052 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001053 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001054 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1055 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001056 + reader now allows \r characters to be quoted (previously it only allowed
1057 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001058 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001059 + Dialect classes passed to the module are no longer instantiated by
1060 the module before being parsed (the former validation scheme required
1061 this, but the mechanism was unreliable).
1062 + The dialect registry now contains instances of the internal
1063 C-coded dialect type, rather than references to python objects.
1064 + the internal c-coded dialect type is now immutable.
1065 + register_dialect now accepts the same keyword dialect specifications
1066 as the reader and writer, allowing the user to register dialects
1067 without first creating a dialect class.
1068 + a configurable limit to the size of parsed fields has been added -
1069 previously, an unmatched quote character could result in the entire
1070 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001071 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001072 the parser field size limit (returning the former limit). The initial
1073 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001074 + A line_num attribute has been added to the reader object, which tracks
1075 the number of lines read from the source iterator. This is not
1076 the same as the number of records returned, as records can span
1077 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001078 + reader and writer objects were not being registered with the cyclic-GC.
1079 This has been fixed.
1080
Brett Cannone6539c42005-01-08 02:43:53 +00001081- _DummyThread objects in the threading module now delete self.__block that is
1082 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1083 lock primitives tend to be limited in number and thus should not be wasted on
1084 a _DummyThread object. Fixes bug #1089632.
1085
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001086- The imghdr module now detects Exif files.
1087
Raymond Hettinger6065d322004-12-20 23:51:53 +00001088- StringIO.truncate() now correctly adjusts the size attribute.
1089 (Bug #951915).
1090
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001091- locale.py now uses an updated locale alias table (built using
1092 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1093 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001094 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001095
Raymond Hettinger3557f422004-12-07 12:02:02 +00001096- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1097
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001098- the pickle module no longer accepts the deprecated None option in the
1099 args tuple returned by __reduce__().
1100
Brett Cannon84667c02004-12-07 03:25:18 +00001101- optparse now optionally imports gettext. This allows its use in setup.py.
1102
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001103- the pickle module no longer uses the deprecated bin parameter.
1104
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001105- the shelve module no longer uses the deprecated binary parameter.
1106
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001107- the pstats module no longer uses the deprecated ignore() method.
1108
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001109- the filecmp module no longer uses the deprecated use_statcache argument.
1110
Raymond Hettinger664347b2004-12-04 21:21:53 +00001111- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1112 extended or overridden by subclasses. Formerly, the subclassed method would
1113 be ignored by the rest of the module. (Bug #1078905).
1114
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001115- heapq.nsmallest() and heapq.nlargest() now support key= arguments with

Walter Dörwald36733692004-12-22 12:50:50 +00001118- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1119 once when a size argument is given. This prevents a buffer overflow in the
1120 tokenizer with very long source lines.
1121
Barry Warsaw538561e2006-01-01 21:48:54 +00001122- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1123 immediately after creating the object, without any intervening
1124 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001125
Skip Montanaro05885812005-01-16 20:48:27 +00001126- The reconvert.quote function can now emit triple-quoted strings. The
1127 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001128
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001129- ``UserString.MutableString`` now supports negative indices in
1130 ``__setitem__`` and ``__delitem__``
1131
Greg Ward40407942005-03-05 02:53:17 +00001132- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1133 correctly.
1134
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001135- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1136 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1137 character even if the user has passed a size parameter to get a proper
1138 line ending. Remove the special handling of a "\r\n" that has been split
1139 between two lines.
1140
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001141- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1142 about illegal code points. The codec now supports PEP 293 style error
1143 handlers.
1144
Walter Dörwald78a78b02005-09-01 12:04:29 +00001145- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001146 from the input stream, so that the output is a byte string in the correct
1147 encoding instead of a unicode string.

Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001149- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1150 considering it exactly like a '*'.
1151
Walter Dörwald007f8df2005-10-09 19:42:27 +00001152- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1153 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001154
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001155- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1156
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001157- Patch #1413711: Certain patterns of differences were making difflib
1158 touch the recursion limit.
1159
Walter Dörwald58917a62006-03-31 15:26:22 +00001160- Bug #947906: An object oriented interface has been added to the calendar
1161 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001162 called as a script (e.g. via ``python -mcalendar``). Localized month and
1163 weekday names can be ouput (even if an exotic encoding is used) using
1164 special classes that use unicode.

1173
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001174- Build support for Win64-AMD64 was added.
1175
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001176- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1177
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001178- Patch #881820: look for openpty and forkpty also in libbsd.
1179
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001180- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1181 The zlib module is now builtin on Windows.
1182
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001183- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1184
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001185- Bug #1189330: configure did not correctly determine the necessary
1186 value of LINKCC if python was built with GCC 4.0.
1187
Trent Mick8321b422005-07-26 02:29:21 +00001188- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1189 vulnerability in zlib 1.2.1 and 1.2.2.
1190
Brett Cannon08cd5982005-04-24 22:26:38 +00001191- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1192 flags that change binary compatibility. Changes were also made to
1193 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001194 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001195
Bob Ippolitoed233462005-03-29 13:47:59 +00001196- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1197 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1198 no longer exists). This configure patch makes things right.
1199
Martin v. Löwise2713be2005-03-08 15:03:08 +00001200- Bug #1158607: Build with --disable-unicode again.
1201
Brett Cannon46d96232005-02-16 00:07:19 +00001202- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1203 defined. Discovered as a result of not being able to build on OS X.
1204
Brett Cannon516592f2004-12-07 00:42:59 +00001205- setup.py now uses the directories specified in LDFLAGS using the -L option
1206 and in CPPFLAGS using the -I option for adding library and include
1207 directories, respectively, for compiling extension modules against. This has
1208 led to the core being compiled using the values in CPPFLAGS. It also removes
1209 the need for the special-casing of both DarwinPorts and Fink for darwin since
1210 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1211 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1212 Fink, ``-I/opt/local/include`` for DarwinPorts).
1213
Brett Cannon43802422005-02-10 20:48:03 +00001214- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1215 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1216 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1217 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001219C API
1220-----
1221
Tim Petersc9d78aa2006-03-26 23:27:58 +00001222- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1223 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1224 is obtained via the ``PyObject_`` family, it must be released via the
1225 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1226 always been officially true, but when Python's small-object allocator was
1227 introduced, an attempt was made to cater to a few extension modules
1228 discovered at the time that obtained memory via ``PyObject_New`` but
1229 released it via ``PyMem_DEL``. It's years later, and if such code still
1230 exists it will fail now (probably with segfaults, but calling wrong
1231 low-level memory management functions can yield many symptoms).
1232
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001233- Added a C API for set and frozenset objects.
1234

1236
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001237- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1238 mapping argument now. This string is used as a mapping table. Byte values
1239 greater than the length of the string and 0xFFFE are treated as undefined
1240 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001247
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001248- Patch #1276356: New resource "urlfetch" is implemented. This enables
1249 even impatient people to run tests that require remote files.
