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. Löwis879768d2006-05-11 13:28:43 +000015- WindowsError now has two error code attributes: errno, which carries
16 the error values from errno.h, and winerror, which carries the error
17 values from winerror.h. Previous versions put the winerror.h values
18 (from GetLastError()) into the errno attribute.
19
Martin v. Löwis77736712006-05-04 05:51:03 +000020- Patch #1475845: Raise IndentationError for unexpected indent.
21
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000022- Patch #1479181: split open() and file() from being aliases for each other.
23
Thomas Heller1b046642006-04-18 18:51:06 +000024- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
25 by converting these apis from macros into exported functions again:
26
27 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
28 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
29 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
30 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
31 PyRun_String Py_CompileString
32
Martin v. Löwis45294a92006-04-18 06:24:08 +000033- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
34
Martin v. Löwis19ab6c92006-04-16 18:55:50 +000035- All uses of PyStructSequence_InitType have been changed to initialize
36 the type objects only once, even if the interpreter is initialized
37 multiple times.
38
Neal Norwitz61546162006-04-14 05:20:28 +000039- Bug #1454485, array.array('u') could crash the interpreter. This was
40 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
41 to unicode when it didn't make sense. 'u#' now requires a unicode string.
42
43- Py_UNICODE is unsigned. It was always documented as unsigned, but
44 due to a bug had a signed value in previous versions.
45
Tim Peters3a5e8b12006-04-11 01:44:07 +000046- Patch #837242: ``id()`` of any Python object always gives a positive
47 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
48 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000049 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000050 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000051
Tim Peters3a5e8b12006-04-11 01:44:07 +000052 def __hash__(self):
53 return id(self) # WRONG
54
55 because a hash result must be a (short) Python int but it was always
56 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000057 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000058 was always usable as a hash value before this patch. That's no longer
59 necessarily so.
60
61- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000062 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000063 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000064 #1454844)
65
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000066- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
67 involving generators that have paused outside of any ``try`` or ``with``
68 blocks. (In 2.5a1, a paused generator that was part of a reference
69 cycle could not be garbage collected, regardless of whether it was
70 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +000071
Anthony Baxter51bcb682006-04-05 14:51:42 +000072Extension Modules
73-----------------
74
Tim Peters8931ff12006-05-13 23:28:20 +000075- On Win32, os.listdir now supports arbitrarily-long Unicode path names
Martin v. Löwis682b1bb2006-05-12 12:27:28 +000076 (up to the system limit of 32K characters).
77
Tim Petersad2ef332006-05-10 02:43:01 +000078- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
Martin v. Löwisd4e3bb32006-05-06 16:32:54 +000079 As a result, these functions now raise WindowsError instead of OSError.
Martin v. Löwis8e0d4942006-05-04 10:08:42 +000080
Martin v. Löwis86725192006-05-01 06:28:01 +000081- Calling Tk_Init twice is refused if the first call failed as that
82 may deadlock.
83
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000084- Patch #1191065: Fix preprocessor problems on systems where recvfrom
85 is a macro.
86
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000087- Bug #1467952: os.listdir() now correctly raises an error if readdir()
88 fails with an error condition.
89
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000090- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
91
92- Bug #1117761: bsddb.*open() no longer raises an exception when using
93 the cachesize parameter.
94
95- Bug #1149413: bsddb.*open() no longer raises an exception when using
96 a temporary db (file=None) with the 'n' flag to truncate on open.
97
98- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
99 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000100
Armin Rigoa9017c32006-04-19 11:50:27 +0000101- Patch #1062014: AF_UNIX sockets under Linux have a special
102 abstract namespace that is now fully supported.
103
Anthony Baxter51bcb682006-04-05 14:51:42 +0000104Library
105-------
106
Georg Brandl19564802006-05-10 17:13:20 +0000107- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
108 stdout arguments, making it possible to redirect input and output
109 for remote debugging.
110
Georg Brandl38c6a222006-05-10 16:26:03 +0000111- Patch #1484695: Update the tarfile module to version 0.8. This fixes
112 a couple of issues, notably handling of long file names using the
113 GNU LONGNAME extension.
114
Tim Petersad2ef332006-05-10 02:43:01 +0000115- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
116 new flag when ``name`` is already the name of an option flag.
117
Georg Brandl1bb62302006-05-03 18:18:32 +0000118- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
119 package.
120
Georg Brandl3583cff2006-04-30 18:14:54 +0000121- Patch #1472854: make the rlcompleter.Completer class usable on non-
122 UNIX platforms.
123
Georg Brandlfa42bd72006-04-30 07:06:11 +0000124- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
125
Tim Peters711bf302006-04-25 03:31:36 +0000126- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
127 a doctest to be skipped (the code is not run, and the expected output
128 or exception is ignored).
129
Nick Coghlanda2268f2006-04-24 04:37:15 +0000130- Fixed contextlib.nested to cope with exceptions being raised and
131 caught inside exit handlers.
132
Greg Wardab05edc2006-04-23 03:47:58 +0000133- Updated optparse module to Optik 1.5.1 (allow numeric constants in
134 hex, octal, or binary; add ``append_const`` action; keep going if
135 gettext cannot be imported; added ``OptionParser.destroy()`` method;
136 added ``epilog`` for better help generation).
137
Tim Peters21fbd572006-04-21 21:18:10 +0000138- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
139 called from a thread spawned as a side effect of importing a module.
140
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000141- The pydoc module now supports documenting packages contained in
142 .zip or .egg files.
143
144- The pkgutil module now has several new utility functions, such
145 as ``walk_packages()`` to support working with packages that are either
146 in the filesystem or zip files.
147
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000148- The mailbox module can now modify and delete messages from
149 mailboxes, in addition to simply reading them. Thanks to Gregory
150 K. Johnson for writing the code, and to the 2005 Google Summer of
151 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000152
Tim Petersc7605f22006-04-17 21:12:33 +0000153- The ``__del__`` method of class ``local`` in module ``_threading_local``
154 returned before accomplishing any of its intended cleanup.

157
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000158- Patch #1063914: Add Tkinter.Misc.clipboard_get().
159
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000160- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
161
Anthony Baxtere29002c2006-04-12 12:07:31 +0000162- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
163 Windows. Bug #1469163.
164
Phillip J. Eby47032112006-04-11 01:07:43 +0000165- The warnings, linecache, inspect, traceback, site, and doctest modules
166 were updated to work correctly with modules imported from zipfiles or
167 via other PEP 302 __loader__ objects.
168
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000169- Patch #1467770: Reduce usage of subprocess._active to processes which
170 the application hasn't waited on.
171
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000172- Patch #1462222: Fix Tix.Grid.
173
Neal Norwitza31bf182006-04-09 03:35:43 +0000174- Fix exception when doing glob.glob('anything*/')
175
Skip Montanaro262fb922006-04-21 02:31:07 +0000176- The pstats.Stats class accepts an optional stream keyword argument to
177 direct output to an alternate file-like object.
178
Anthony Baxter51bcb682006-04-05 14:51:42 +0000179Build
180-----
181
Martin v. Löwisb75d43d2006-04-29 12:37:25 +0000182- Patch #1471883: Add --enable-universalsdk.
183
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000184- The Makefile now has a reindent target, which runs reindent.py on
185 the library.
186
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000187- Patch #1470875: Building Python with MS Free Compiler
188
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000189- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000190
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000191- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
192 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000193 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000194 CXX from --with-cxx-main, see description in README.
195
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000196- Patch #1429775: Link extension modules with the shared libpython.
197
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000198- Fixed a libffi build problem on MIPS systems.
199
Anthony Baxter51bcb682006-04-05 14:51:42 +0000200C API
201-----
202
Tim Peters8931ff12006-05-13 23:28:20 +0000203- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
204 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
205 and "%zu" for unsigned integers of type ``size_t``.
206
Anthony Baxter51bcb682006-04-05 14:51:42 +0000207Tests
208-----
209
Nick Coghlanda2268f2006-04-24 04:37:15 +0000210- test_contextlib now checks contextlib.nested can cope with exceptions
211 being raised and caught inside exit handlers.
212
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000213- test_cmd_line now checks operation of the -m and -c command switches
214
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000215- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
216 it separately and by hand. It also wasn't cleaning up its changes to
217 the current Decimal context.
218
Thomas Woutersabd08882006-04-26 15:53:30 +0000219- regrtest.py now has a -M option to run tests that test the new limits of
220 containers, on 64-bit architectures. Running these tests is only sensible
221 on 64-bit machines with more than two gigabytes of memory. The argument
222 passed is the maximum amount of memory for the tests to use.
223
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +0000224Tools
225-----
226
227- Added the Python benchmark suite pybench to the Tools/ directory;
228 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000230Documentation
231-------------
232
Tim Petersb06d28c2006-05-12 01:57:59 +0000233- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
234
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000235- PEP 343: Added Context Types section to the library reference
236 and attempted to bring other PEP 343 related documentation into
237 line with the implementation and/or python-dev discussions.
238
Tim Peters8dc73d22006-04-24 02:03:16 +0000239- Bug #1337990: clarified that ``doctest`` does not support examples
240 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +0000241

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000243What's New in Python 2.5 alpha 1?
244=================================
245
Anthony Baxterebed3f62006-04-03 15:03:44 +0000246*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000247
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000248Core and builtins
249-----------------
250
Nick Coghlan43832302006-04-23 17:04:07 +0000251- PEP 338: -m command line switch now delegates to runpy.run_module
252 allowing it to support modules in packages and zipfiles
253
Martin v. Löwisc661b882006-04-20 04:54:23 +0000254- On Windows, .DLL is not an accepted file name extension for
255 extension modules anymore; extensions are only found if they
256 end in .PYD.
257
Martin v. Löwisea62d252006-04-03 10:56:49 +0000258- Bug #1421664: sys.stderr.encoding is now set to the same value as
259 sys.stdout.encoding.
260
Neal Norwitz92e212f2006-04-03 04:48:37 +0000261- __import__ accepts keyword arguments.
262
Georg Brandlccadf842006-03-31 18:54:53 +0000263- Patch #1460496: round() now accepts keyword arguments.
264
Anthony Baxter262c00a2006-03-30 10:53:17 +0000265- Fixed bug #1459029 - unicode reprs were double-escaped.
266
Hye-Shik Changd478f342006-03-23 12:32:36 +0000267- Patch #1396919: The system scope threads are reenabled on FreeBSD
268 5.4 and later versions.
269
Neal Norwitze98ccf62006-03-23 05:39:47 +0000270- Bug #1115379: Compiling a Unicode string with an encoding declaration
271 now gives a SyntaxError.
272
Georg Brandlabd1ff82006-03-18 07:59:59 +0000273- Previously, Python code had no easy way to access the contents of a
274 cell object. Now, a ``cell_contents`` attribute has been added
275 (closes patch #1170323).
276
Tim Peterscf79aac2006-03-16 01:14:46 +0000277- Patch #1123430: Python's small-object allocator now returns an arena to
278 the system ``free()`` when all memory within an arena becomes unused
279 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
280 freed. Some applications will see a drop in virtual memory size now,
281 especially long-running applications that, from time to time, temporarily
282 use a large number of small objects. Note that when Python returns an
283 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000284 platform C library will in turn return that memory to the operating system.
285 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000286 appears to be effective at least on Microsoft C and gcc-based systems.
287 Thanks to Evan Jones for hard work and patience.
288
Georg Brandl533ff6f2006-03-08 18:09:27 +0000289- Patch #1434038: property() now uses the getter's docstring if there is
290 no "doc" argument given. This makes it possible to legitimately use
291 property() as a decorator to produce a read-only property.
292
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000293- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
294 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
295 of requiring an int or long in slicing and a few other contexts, enabling
296 other objects (e.g. Numeric Python's integers) to be used as slice indices.
297
Neal Norwitz995acdf2006-03-07 05:01:00 +0000298- Fixed various bugs reported by Coverity's Prevent tool.
299
Brett Cannonbf364092006-03-01 04:25:17 +0000300- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
301 new exception base class, BaseException, which has a new message attribute.
302 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
303 Raising a string exception now raises a DeprecationWarning.
304
Thomas Woutersfb609f42006-02-28 16:37:25 +0000305- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
306 explicitly relative, using 'from .module import name' to mean 'from the same
307 package as this module is in. Imports without dots still default to the
308 old relative-then-absolute, unless 'from __future__ import
309 absolute_import' is used.
310
Brett Cannona7446e32006-02-27 23:39:10 +0000311- Properly check if 'warnings' raises an exception (usually when a filter set
312 to "error" is triggered) when raising a warning for raising string
313 exceptions.
314
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000315- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000316 The name was removed from Include/code.h.
317
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000318- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000319
Guido van Rossum1968ad32006-02-25 22:38:04 +0000320- Patch 1433928:
321 - The copy module now "copies" function objects (as atomic objects).
322 - dict.__getitem__ now looks for a __missing__ hook before raising
323 KeyError.
324
Tim Peters84ef21c2006-02-28 20:39:06 +0000325- PEP 343: with statement implemented. Needs ``from __future__ import
326 with_statement``. Use of 'with' as a variable will generate a warning.
327 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000328 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000329 The following objects have __context__ methods:
330 - The built-in file type.
331 - The thread.LockType type.
332 - The following types defined by the threading module:
333 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
334 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000335
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000336- Fix the encodings package codec search function to only search
337 inside its own package. Fixes problem reported in patch #1433198.
338
339 Note: Codec packages should implement and register their own
340 codec search function. PEP 100 has the details.
341
Martin v. Löwis18e16552006-02-15 17:27:45 +0000342- PEP 353: Using ssize_t as the index type.
343
Neal Norwitzfc76d632006-01-10 06:03:13 +0000344- Patch #1400181, fix unicode string formatting to not use the locale.
345 This is how string objects work. u'%f' could use , instead of .
346 for the decimal point. Now both strings and unicode always use periods.
347
Neal Norwitz671b9e32006-01-09 07:07:12 +0000348- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
349 configure would break checking curses.h.
350
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000351- Bug #959576: The pwd module is now builtin. This allows Python to be
352 built on UNIX platforms without $HOME set.
353
Neal Norwitzc10978f2005-12-19 06:07:16 +0000354- Bug #1072182, fix some potential problems if characters are signed.
355
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000356- Bug #889500, fix line number on SyntaxWarning for global declarations.
357
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000358- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
359
Neal Norwitze7214a12005-12-18 05:03:17 +0000360- Support for converting hex strings to floats no longer works.
361 This was not portable. float('0x3') now raises a ValueError.
362
Barry Warsaw2a38a862005-12-18 01:27:35 +0000363- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000364 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000365 is now displayed in interactive prompt banner.
366
Georg Brandlfa166682005-12-17 21:45:17 +0000367- Implementation of PEP 341 - Unification of try/except and try/finally.
368 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000369 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000370
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000371- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
372 now encodes backslash correctly.
373
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000374- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
375
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000376- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000377 and long longs.
378
Neal Norwitz67715f02005-11-09 06:59:35 +0000379- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000380 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000381 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000382
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000383- Replaced most Unicode charmap codecs with new ones using the
384 new Unicode translate string feature in the builtin charmap
385 codec; the codecs were created from the mapping tables available
386 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
387 encodings now include a mapping for the Apple logo)
388
Tim Peterse3547fd2005-12-16 23:13:57 +0000389- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000390
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000391- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000392
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000393- A new AST parser implementation was completed. The abstract
394 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000395 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000396
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000397- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000398 The following code now raises a SyntaxError: foo(a = i for i in range(10))
399
Neal Norwitz708e51a2005-10-03 04:48:15 +0000400- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
401
Neal Norwitz11bd1192005-10-03 00:54:56 +0000402- SF Bug #887946: fix segfault when redirecting stdin from a directory.
403 Provide a warning when a directory is passed on the command line.
404
Neal Norwitz40d37812005-10-02 01:48:49 +0000405- Fix segfault with invalid coding.
406
407- SF bug #772896: unknown encoding results in MemoryError.
408
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000409- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000410 supported a __len__() method which evaluated to False when the iterator
411 was empty.
412
Guido van Rossum630db602005-09-20 18:49:54 +0000413- On 64-bit platforms, when __len__() returns a value that cannot be
414 represented as a C int, raise OverflowError.
415
Skip Montanarof8948ca2005-09-19 03:54:46 +0000416- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000417 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000418
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000419- SF bug #893549: parsing keyword arguments was broken with a few format
420 codes.
421
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000422- Changes donated by Elemental Security to make it work on AIX 5.3
423 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
424 bug #105470: test_pwd fails on 64bit system (Opteron).
425
Guido van Rossum539c6622005-09-14 17:49:54 +0000426- Changes donated by Elemental Security to make it work on HP-UX 11 on
427 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
428
Georg Brandl4550b8d2005-08-26 06:43:52 +0000429- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000430 (fixes bug #1119418).
431
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000432- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
433
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000434- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
435 exceptions that cause a function to exit.
436
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000437- The implementation of set() and frozenset() was revised to use its
438 own internal data structure. Memory consumption is reduced by 1/3
439 and there are modest speed-ups as well. The API is unchanged.
440
Tim Petersde7990b2005-07-17 23:45:23 +0000441- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
442
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000443- SF bug #1229429: PyObject_CallMethod failed to decrement some
444 reference counts in some error exit cases.
445
Tim Petersecc6e6a2005-07-10 22:30:55 +0000446- SF bug #1185883: Python's small-object memory allocator took over
447 a block managed by the platform C library whenever a realloc specified
448 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000449 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000450 portable way to copy data from the C-managed block into Python's
451 small-object space without risking a memory fault. Python's small-object
452 realloc now leaves such blocks under the control of the platform C
453 realloc.
454
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000455- SF bug #1232517: An overflow error was not detected properly when
456 attempting to convert a large float to an int in os.utime().
457
Raymond Hettinger3296e692005-06-29 23:29:56 +0000458- SF bug #1224347: hex longs now print with lowercase letters just
459 like their int counterparts.
460
Michael W. Hudson188d4362005-06-20 16:52:57 +0000461- SF bug #1163563: the original fix for bug #1010677 ("thread Module
462 Breaks PyGILState_Ensure()") broke badly in the case of multiple
463 interpreter states; back out that fix and do a better job (see
464 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
465 for a longer write-up of the problem).
466
Michael W. Hudsondf888462005-06-03 14:41:55 +0000467- SF patch #1180995: marshal now uses a binary format by default when
468 serializing floats.
469
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000470- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
471 the routines that promise to produce IEEE 754 binary representations
472 of floats now simply copy bytes around.
473
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000474- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
475 278.
476
Brett Cannonc3647ac2005-04-26 03:45:26 +0000477- patch #1109424: int, long, float, complex, and unicode now check for the
478 proper magic slot for type conversions when subclassed. Previously the
479 magic slot was ignored during conversion. Semantics now match the way
480 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000481 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000482 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000483 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000484
Barry Warsawc8d907c2005-04-19 23:43:40 +0000485- Descriptors defined in C with a PyGetSetDef structure, where the setter is
486 NULL, now raise an AttributeError when attempting to set or delete the
487 attribute. Previously a TypeError was raised, but this was inconsistent
488 with the equivalent pure-Python implementation.
489
Michael W. Hudson774479c2005-04-18 08:46:17 +0000490- It is now safe to call PyGILState_Release() before
491 PyEval_InitThreads() (note that if there is reason to believe there
492 are multiple threads around you still must call PyEval_InitThreads()
493 before using the Python API; this fix is for extension modules that
494 have no way of knowing if Python is multi-threaded yet).
495
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000496- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
497 disabled caused a crash.
498
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000499- Bug #1165306: instancemethod_new allowed the creation of a method
500 with im_class == im_self == NULL, which caused a crash when called.
501
Tim Petersecc6e6a2005-07-10 22:30:55 +0000502- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000503 fixes the crash seen in bug #1165761
504
Raymond Hettinger96229b12005-03-11 06:49:40 +0000505- Added two new builtins, any() and all().
506
Brett Cannon409d8f22005-03-05 06:47:57 +0000507- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000508 (e.g., ``class C(): pass`` is no longer a syntax error).
509 Patch #1176012 added support to the 'parser' module and 'compiler' package
510 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000511
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000512- Patch #1115086: Support PY_LONGLONG in structmember.
513
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000514- Bug #1155938: new style classes did not check that __init__() was
515 returning None.
516
Tim Petersecc6e6a2005-07-10 22:30:55 +0000517- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000518 ('\') with a specific error message.
519
Martin v. Löwisff232d72005-03-03 09:24:38 +0000520- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
521
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000522- Bug #1124295: the __name__ attribute of file objects was
523 inadvertently made inaccessible in restricted mode.
524
Tim Petersecc6e6a2005-07-10 22:30:55 +0000525- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000526 an ferror() call.
527
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000528- min() and max() now support key= arguments with the same meaning as in
529 list.sort().
530
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000531- The peephole optimizer now performs simple constant folding in expressions:
532 (2+3) --> (5).
533
Raymond Hettingera422c342005-01-11 03:03:27 +0000534- set and frozenset objects can now be marshalled. SF #1098985.
535
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000536- Bug #1077106: Poor argument checking could cause memory corruption
537 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000538
Jeremy Hyltonab630502005-02-04 18:44:06 +0000539- The parser did not complain about future statements in illegal
540 positions. It once again reports a syntax error if a future
541 statement occurs after anything other than a doc string.
542
Neil Schemenauercf52c072005-08-12 17:34:58 +0000543- Change the %s format specifier for str objects so that it returns a
544 unicode instance if the argument is not an instance of basestring and
545 calling __str__ on the argument returns a unicode instance.
546
Tim Petersf4e69282006-02-27 17:15:31 +0000547- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
548 current thread state when the auto-GIL-state machinery knows about
549 it (since the thread state is being deleted, continuing to remember it
550 can't help, but can hurt if another thread happens to get created with
551 the same thread id).
552
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000553Extension Modules
554-----------------
555
Georg Brandl43f08a82006-03-31 18:01:16 +0000556- Patch #1380952: fix SSL objects timing out on consecutive read()s
557
Neal Norwitz05a45592006-03-20 06:30:08 +0000558- Patch #1309579: wait3 and wait4 were added to the posix module.
559
Anthony Baxterfa869072006-03-20 05:21:58 +0000560- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
561 In addition, the existing ulaw code was updated.
562
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000563- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000564 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000565
Neal Norwitz10be10c2006-03-16 06:50:13 +0000566- Everything under lib-old was removed. This includes the following modules:
567 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000568 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000569 util, whatsound, whrandom, zmod
570
571- The following modules were removed: regsub, reconvert, regex, regex_syntax.
572

741-------
742
Nick Coghlan43832302006-04-23 17:04:07 +0000743- PEP 338: new module runpy defines a run_module function to support
744 executing modules which provide access to source code or a code object
745 via the PEP 302 import mechanisms.

Georg Brandl828fdef2006-04-01 08:59:03 +0000758 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000759 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000760 module will not be built.
761
Tim Petersc17976e2006-04-01 00:26:53 +0000762- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
763 aren't officially supported here, and trying to use them will probably
764 raise an exception some day. But dicts have been allowed, and "mostly
765 worked", so support for them won't go away without warning.
766
Georg Brandl338ef7d2006-03-31 18:42:16 +0000767- Bug #1445068: getpass.getpass() can now be given an explicit stream

785
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000786- email 4.0 package now integrated. This is largely the same as the email 3.0
787 package that was included in Python 2.3, except that PEP 8 module names are
788 now used (e.g. mail.message instead of email.Message). The MIME classes
789 have been moved to a subpackage (e.g. email.mime.text instead of
790 email.MIMEText). The old names are still supported for now. Several
791 deprecated Message methods have been removed and lots of bugs have been
792 fixed. More details can be found in the email package documentation.
793
Walter Dörwald40108c92006-03-27 08:15:44 +0000794- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
795 (a subclass of tuple) that provides incremental decoders and encoders
796 (a way to use stateful codecs without the stream API). Python functions
797 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
798 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
799 have been added.

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

Brett Cannon3cbd0382005-12-16 22:49:23 +0000877- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +0000878 SHA1, 224, 256, 384, and 512. Note that recent developments make the
879 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
880 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
881 Ronald L. Rivest offered this advice for Python:
882
883 "The consensus of researchers in this area (at least as
884 expressed at the NIST Hash Function Workshop 10/31/05),
885 is that SHA-256 is a good choice for the time being, but
886 that research should continue, and other alternatives may
887 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000888
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000889- Added a subset of Fredrik Lundh's ElementTree package. Available

942 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000943 correct line numbers for decoding errors in source code.

982 Bug #1224621.
983
Raymond Hettinger68c04532005-06-10 11:05:19 +0000984- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000985 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000986 the generate_tokens() function now accepts a callable argument that
987 terminates by raising StopIteration.
988
Georg Brandl9166e1a2005-06-04 09:20:03 +0000989- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1004
Raymond Hettinger267b8682005-03-27 10:47:39 +00001005- decimal operator and comparison methods now return NotImplemented
1006 instead of raising a TypeError when interacting with other types. This
1007 allows other classes to implement __radd__ style methods and have them
1008 work as expected.
1009
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001010- Bug #1163325: Decimal infinities failed to hash. Attempting to
1011 hash a NaN raised an InvalidOperation instead of a TypeError.
1012
Tim Petersecc6e6a2005-07-10 22:30:55 +00001013- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1047
Guido van Rossumd0641422005-02-03 15:01:24 +00001048- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1049 disables recursive traversal through instance attributes, which can
1050 be exploited in various ways.
1051
Tim Peterse3547fd2005-12-16 23:13:57 +00001052- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001053 flags on the HTTP listening socket.
1054
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001055- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1056 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1057
Tim Peterse3547fd2005-12-16 23:13:57 +00001058- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001059 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1060

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001063- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1064
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001065- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1066
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001067- Enhancements to the csv module:
1068
1069 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001070 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001071 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001072 + Dialect parameter parsing has been re-implemented to improve error
1073 reporting.
1074 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1075 dictates.
1076 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001077 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001078 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001079 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1080 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001081 + reader now allows \r characters to be quoted (previously it only allowed
1082 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001083 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001084 + Dialect classes passed to the module are no longer instantiated by
1085 the module before being parsed (the former validation scheme required
1086 this, but the mechanism was unreliable).
1087 + The dialect registry now contains instances of the internal
1088 C-coded dialect type, rather than references to python objects.
1089 + the internal c-coded dialect type is now immutable.
1090 + register_dialect now accepts the same keyword dialect specifications
1091 as the reader and writer, allowing the user to register dialects
1092 without first creating a dialect class.
1093 + a configurable limit to the size of parsed fields has been added -
1094 previously, an unmatched quote character could result in the entire
1095 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001096 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001097 the parser field size limit (returning the former limit). The initial
1098 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001099 + A line_num attribute has been added to the reader object, which tracks
1100 the number of lines read from the source iterator. This is not
1101 the same as the number of records returned, as records can span
1102 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001103 + reader and writer objects were not being registered with the cyclic-GC.
1104 This has been fixed.
1105
Brett Cannone6539c42005-01-08 02:43:53 +00001106- _DummyThread objects in the threading module now delete self.__block that is
1107 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1108 lock primitives tend to be limited in number and thus should not be wasted on
1109 a _DummyThread object. Fixes bug #1089632.
1110
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001111- The imghdr module now detects Exif files.
1112
Raymond Hettinger6065d322004-12-20 23:51:53 +00001113- StringIO.truncate() now correctly adjusts the size attribute.
1114 (Bug #951915).
1115
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001116- locale.py now uses an updated locale alias table (built using
1117 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1118 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001119 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001120
Raymond Hettinger3557f422004-12-07 12:02:02 +00001121- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1122
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001123- the pickle module no longer accepts the deprecated None option in the
1124 args tuple returned by __reduce__().
1125
Brett Cannon84667c02004-12-07 03:25:18 +00001126- optparse now optionally imports gettext. This allows its use in setup.py.
1127
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001128- the pickle module no longer uses the deprecated bin parameter.
1129
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001130- the shelve module no longer uses the deprecated binary parameter.
1131

1133
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001134- the filecmp module no longer uses the deprecated use_statcache argument.
1135
Raymond Hettinger664347b2004-12-04 21:21:53 +00001136- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1137 extended or overridden by subclasses. Formerly, the subclassed method would
1138 be ignored by the rest of the module. (Bug #1078905).
1139
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001140- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001141 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001142
Walter Dörwald36733692004-12-22 12:50:50 +00001143- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1144 once when a size argument is given. This prevents a buffer overflow in the
1145 tokenizer with very long source lines.
1146
Barry Warsaw538561e2006-01-01 21:48:54 +00001147- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1148 immediately after creating the object, without any intervening
1149 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001150
Skip Montanaro05885812005-01-16 20:48:27 +00001151- The reconvert.quote function can now emit triple-quoted strings. The
1152 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001153
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001154- ``UserString.MutableString`` now supports negative indices in
1155 ``__setitem__`` and ``__delitem__``
1156
Greg Ward40407942005-03-05 02:53:17 +00001157- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1158 correctly.
1159
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001160- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1161 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1162 character even if the user has passed a size parameter to get a proper
1163 line ending. Remove the special handling of a "\r\n" that has been split
1164 between two lines.
1165
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001166- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1167 about illegal code points. The codec now supports PEP 293 style error
1168 handlers.
1169
Walter Dörwald78a78b02005-09-01 12:04:29 +00001170- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001171 from the input stream, so that the output is a byte string in the correct
1172 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001173
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001174- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1175 considering it exactly like a '*'.
1176
Walter Dörwald007f8df2005-10-09 19:42:27 +00001177- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1178 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001179
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001180- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1181
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001182- Patch #1413711: Certain patterns of differences were making difflib
1183 touch the recursion limit.
1184
Walter Dörwald58917a62006-03-31 15:26:22 +00001185- Bug #947906: An object oriented interface has been added to the calendar
1186 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001187 called as a script (e.g. via ``python -mcalendar``). Localized month and
1188 weekday names can be ouput (even if an exotic encoding is used) using
1189 special classes that use unicode.

1192-----
1193
Neal Norwitz602d3392006-03-31 08:21:40 +00001194- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1195 by using -mieee gcc option.
1196

1198
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001199- Build support for Win64-AMD64 was added.
1200
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001201- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1202
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001203- Patch #881820: look for openpty and forkpty also in libbsd.
1204
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001205- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1206 The zlib module is now builtin on Windows.
1207
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001208- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1209
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001210- Bug #1189330: configure did not correctly determine the necessary
1211 value of LINKCC if python was built with GCC 4.0.
1212
Trent Mick8321b422005-07-26 02:29:21 +00001213- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1214 vulnerability in zlib 1.2.1 and 1.2.2.
1215
Brett Cannon08cd5982005-04-24 22:26:38 +00001216- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1217 flags that change binary compatibility. Changes were also made to
1218 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001219 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001220
Bob Ippolitoed233462005-03-29 13:47:59 +00001221- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1222 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1223 no longer exists). This configure patch makes things right.
1224
Martin v. Löwise2713be2005-03-08 15:03:08 +00001225- Bug #1158607: Build with --disable-unicode again.
1226
Brett Cannon46d96232005-02-16 00:07:19 +00001227- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1228 defined. Discovered as a result of not being able to build on OS X.
1229
Brett Cannon516592f2004-12-07 00:42:59 +00001230- setup.py now uses the directories specified in LDFLAGS using the -L option
1231 and in CPPFLAGS using the -I option for adding library and include
1232 directories, respectively, for compiling extension modules against. This has
1233 led to the core being compiled using the values in CPPFLAGS. It also removes
1234 the need for the special-casing of both DarwinPorts and Fink for darwin since
1235 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1236 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1237 Fink, ``-I/opt/local/include`` for DarwinPorts).
1238
Brett Cannon43802422005-02-10 20:48:03 +00001239- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1240 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1241 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1242 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001244C API
1245-----
1246
Tim Petersc9d78aa2006-03-26 23:27:58 +00001247- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1248 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1249 is obtained via the ``PyObject_`` family, it must be released via the
1250 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1251 always been officially true, but when Python's small-object allocator was
1252 introduced, an attempt was made to cater to a few extension modules
1253 discovered at the time that obtained memory via ``PyObject_New`` but
1254 released it via ``PyMem_DEL``. It's years later, and if such code still
1255 exists it will fail now (probably with segfaults, but calling wrong
1256 low-level memory management functions can yield many symptoms).
1257
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001258- Added a C API for set and frozenset objects.
1259
Raymond Hettinger66517482004-12-03 11:45:13 +00001260- Removed PyRange_New().
1261
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001262- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1263 mapping argument now. This string is used as a mapping table. Byte values
1264 greater than the length of the string and 0xFFFE are treated as undefined
1265 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001272
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001273- Patch #1276356: New resource "urlfetch" is implemented. This enables
1274 even impatient people to run tests that require remote files.
