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

11
12Core and builtins
13-----------------
14
Thomas Heller1b046642006-04-18 18:51:06 +000015- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
16 by converting these apis from macros into exported functions again:
17
18 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
19 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
20 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
21 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
22 PyRun_String Py_CompileString
23
Martin v. Löwis45294a92006-04-18 06:24:08 +000024- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
25
Martin v. Löwis19ab6c92006-04-16 18:55:50 +000026- All uses of PyStructSequence_InitType have been changed to initialize
27 the type objects only once, even if the interpreter is initialized
28 multiple times.
29
Neal Norwitz61546162006-04-14 05:20:28 +000030- Bug #1454485, array.array('u') could crash the interpreter. This was
31 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
32 to unicode when it didn't make sense. 'u#' now requires a unicode string.
33
34- Py_UNICODE is unsigned. It was always documented as unsigned, but
35 due to a bug had a signed value in previous versions.
36
Tim Peters3a5e8b12006-04-11 01:44:07 +000037- Patch #837242: ``id()`` of any Python object always gives a positive
38 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
39 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000040 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000041 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000042
Tim Peters3a5e8b12006-04-11 01:44:07 +000043 def __hash__(self):
44 return id(self) # WRONG
45
46 because a hash result must be a (short) Python int but it was always
47 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000048 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000049 was always usable as a hash value before this patch. That's no longer
50 necessarily so.
51
52- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000053 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000054 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000055 #1454844)
56
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000057- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
58 involving generators that have paused outside of any ``try`` or ``with``
59 blocks. (In 2.5a1, a paused generator that was part of a reference
60 cycle could not be garbage collected, regardless of whether it was
61 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +000063Extension Modules
64-----------------
65
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000066- Patch #1191065: Fix preprocessor problems on systems where recvfrom
67 is a macro.
68
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000069- Bug #1467952: os.listdir() now correctly raises an error if readdir()
70 fails with an error condition.
71
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000072- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
73
74- Bug #1117761: bsddb.*open() no longer raises an exception when using
75 the cachesize parameter.
76
77- Bug #1149413: bsddb.*open() no longer raises an exception when using
78 a temporary db (file=None) with the 'n' flag to truncate on open.
79
80- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
81 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +000082
Armin Rigoa9017c32006-04-19 11:50:27 +000083- Patch #1062014: AF_UNIX sockets under Linux have a special
84 abstract namespace that is now fully supported.
85
Anthony Baxter51bcb682006-04-05 14:51:42 +000086Library
87-------
88
Greg Wardab05edc2006-04-23 03:47:58 +000089- Updated optparse module to Optik 1.5.1 (allow numeric constants in
90 hex, octal, or binary; add ``append_const`` action; keep going if
91 gettext cannot be imported; added ``OptionParser.destroy()`` method;
92 added ``epilog`` for better help generation).
93
Tim Peters21fbd572006-04-21 21:18:10 +000094- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
95 called from a thread spawned as a side effect of importing a module.
96
Phillip J. Eby17a35f92006-04-18 16:45:14 +000097- New modules: setuptools, easy_install, and pkg_resources, to support
98 building, installing, and using Python eggs, respectively.
99
100- The pydoc module now supports documenting packages contained in
101 .zip or .egg files.
102
103- The pkgutil module now has several new utility functions, such
104 as ``walk_packages()`` to support working with packages that are either
105 in the filesystem or zip files.
106
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000107- The mailbox module can now modify and delete messages from
108 mailboxes, in addition to simply reading them. Thanks to Gregory
109 K. Johnson for writing the code, and to the 2005 Google Summer of
110 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000111
Tim Petersc7605f22006-04-17 21:12:33 +0000112- The ``__del__`` method of class ``local`` in module ``_threading_local``
113 returned before accomplishing any of its intended cleanup.
114
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000115- Patch #790710: Add breakpoint command lists in pdb.
116
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000117- Patch #1063914: Add Tkinter.Misc.clipboard_get().
118
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000119- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
120
Anthony Baxtere29002c2006-04-12 12:07:31 +0000121- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
122 Windows. Bug #1469163.
123
Phillip J. Eby47032112006-04-11 01:07:43 +0000124- The warnings, linecache, inspect, traceback, site, and doctest modules
125 were updated to work correctly with modules imported from zipfiles or
126 via other PEP 302 __loader__ objects.
127
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000128- Patch #1467770: Reduce usage of subprocess._active to processes which
129 the application hasn't waited on.
130
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000131- Patch #1462222: Fix Tix.Grid.

134
Skip Montanaro262fb922006-04-21 02:31:07 +0000135- The pstats.Stats class accepts an optional stream keyword argument to
136 direct output to an alternate file-like object.
137
Anthony Baxter51bcb682006-04-05 14:51:42 +0000138Build
139-----
140
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000141- The Makefile now has a reindent target, which runs reindent.py on
142 the library.
143
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000144- Patch #1470875: Building Python with MS Free Compiler
145
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000146- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000147
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000148- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
149 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000150 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000151 CXX from --with-cxx-main, see description in README.
152
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000153- Patch #1429775: Link extension modules with the shared libpython.

Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000161- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
162 it separately and by hand. It also wasn't cleaning up its changes to
163 the current Decimal context.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000176What's New in Python 2.5 alpha 1?
177=================================
178
Anthony Baxterebed3f62006-04-03 15:03:44 +0000179*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000180
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000181Core and builtins
182-----------------
183
Martin v. Löwisc661b882006-04-20 04:54:23 +0000184- On Windows, .DLL is not an accepted file name extension for
185 extension modules anymore; extensions are only found if they
186 end in .PYD.
187
Martin v. Löwisea62d252006-04-03 10:56:49 +0000188- Bug #1421664: sys.stderr.encoding is now set to the same value as
189 sys.stdout.encoding.
190
Neal Norwitz92e212f2006-04-03 04:48:37 +0000191- __import__ accepts keyword arguments.
192
Georg Brandlccadf842006-03-31 18:54:53 +0000193- Patch #1460496: round() now accepts keyword arguments.
194
Anthony Baxter262c00a2006-03-30 10:53:17 +0000195- Fixed bug #1459029 - unicode reprs were double-escaped.
196
Hye-Shik Changd478f342006-03-23 12:32:36 +0000197- Patch #1396919: The system scope threads are reenabled on FreeBSD
198 5.4 and later versions.
199
Neal Norwitze98ccf62006-03-23 05:39:47 +0000200- Bug #1115379: Compiling a Unicode string with an encoding declaration
201 now gives a SyntaxError.
202
Georg Brandlabd1ff82006-03-18 07:59:59 +0000203- Previously, Python code had no easy way to access the contents of a
204 cell object. Now, a ``cell_contents`` attribute has been added
205 (closes patch #1170323).
206
Tim Peterscf79aac2006-03-16 01:14:46 +0000207- Patch #1123430: Python's small-object allocator now returns an arena to
208 the system ``free()`` when all memory within an arena becomes unused
209 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
210 freed. Some applications will see a drop in virtual memory size now,
211 especially long-running applications that, from time to time, temporarily
212 use a large number of small objects. Note that when Python returns an
213 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000214 platform C library will in turn return that memory to the operating system.
215 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000216 appears to be effective at least on Microsoft C and gcc-based systems.
217 Thanks to Evan Jones for hard work and patience.
218
Georg Brandl533ff6f2006-03-08 18:09:27 +0000219- Patch #1434038: property() now uses the getter's docstring if there is
220 no "doc" argument given. This makes it possible to legitimately use
221 property() as a decorator to produce a read-only property.
222
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000223- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
224 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
225 of requiring an int or long in slicing and a few other contexts, enabling
226 other objects (e.g. Numeric Python's integers) to be used as slice indices.
227
Neal Norwitz995acdf2006-03-07 05:01:00 +0000228- Fixed various bugs reported by Coverity's Prevent tool.
229
Brett Cannonbf364092006-03-01 04:25:17 +0000230- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
231 new exception base class, BaseException, which has a new message attribute.
232 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
233 Raising a string exception now raises a DeprecationWarning.
234
Thomas Woutersfb609f42006-02-28 16:37:25 +0000235- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
236 explicitly relative, using 'from .module import name' to mean 'from the same
237 package as this module is in. Imports without dots still default to the
238 old relative-then-absolute, unless 'from __future__ import
239 absolute_import' is used.
240
Brett Cannona7446e32006-02-27 23:39:10 +0000241- Properly check if 'warnings' raises an exception (usually when a filter set
242 to "error" is triggered) when raising a warning for raising string
243 exceptions.
244
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000245- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000246 The name was removed from Include/code.h.
247
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000248- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000249
Guido van Rossum1968ad32006-02-25 22:38:04 +0000250- Patch 1433928:
251 - The copy module now "copies" function objects (as atomic objects).
252 - dict.__getitem__ now looks for a __missing__ hook before raising
253 KeyError.
254
Tim Peters84ef21c2006-02-28 20:39:06 +0000255- PEP 343: with statement implemented. Needs ``from __future__ import
256 with_statement``. Use of 'with' as a variable will generate a warning.
257 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000258 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000259 The following objects have __context__ methods:
260 - The built-in file type.
261 - The thread.LockType type.
262 - The following types defined by the threading module:
263 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
264 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000265
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000266- Fix the encodings package codec search function to only search
267 inside its own package. Fixes problem reported in patch #1433198.
268
269 Note: Codec packages should implement and register their own
270 codec search function. PEP 100 has the details.
271
Martin v. Löwis18e16552006-02-15 17:27:45 +0000272- PEP 353: Using ssize_t as the index type.
273
Neal Norwitzfc76d632006-01-10 06:03:13 +0000274- Patch #1400181, fix unicode string formatting to not use the locale.
275 This is how string objects work. u'%f' could use , instead of .
276 for the decimal point. Now both strings and unicode always use periods.
277
Neal Norwitz671b9e32006-01-09 07:07:12 +0000278- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
279 configure would break checking curses.h.
280
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000281- Bug #959576: The pwd module is now builtin. This allows Python to be
282 built on UNIX platforms without $HOME set.
283
Neal Norwitzc10978f2005-12-19 06:07:16 +0000284- Bug #1072182, fix some potential problems if characters are signed.
285
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000286- Bug #889500, fix line number on SyntaxWarning for global declarations.
287
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000288- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
289
Neal Norwitze7214a12005-12-18 05:03:17 +0000290- Support for converting hex strings to floats no longer works.
291 This was not portable. float('0x3') now raises a ValueError.
292
Barry Warsaw2a38a862005-12-18 01:27:35 +0000293- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000294 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000295 is now displayed in interactive prompt banner.
296
Georg Brandlfa166682005-12-17 21:45:17 +0000297- Implementation of PEP 341 - Unification of try/except and try/finally.
298 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000299 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000300
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000301- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
302 now encodes backslash correctly.
303
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000304- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
305
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000306- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs

Neal Norwitz67715f02005-11-09 06:59:35 +0000309- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000310 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000311 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000312
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000313- Replaced most Unicode charmap codecs with new ones using the
314 new Unicode translate string feature in the builtin charmap
315 codec; the codecs were created from the mapping tables available
316 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
317 encodings now include a mapping for the Apple logo)
318
Tim Peterse3547fd2005-12-16 23:13:57 +0000319- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000320
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000321- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000322
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000323- A new AST parser implementation was completed. The abstract
324 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000325 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000326
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000327- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000328 The following code now raises a SyntaxError: foo(a = i for i in range(10))
329
Neal Norwitz708e51a2005-10-03 04:48:15 +0000330- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
331
Neal Norwitz11bd1192005-10-03 00:54:56 +0000332- SF Bug #887946: fix segfault when redirecting stdin from a directory.
333 Provide a warning when a directory is passed on the command line.
334
Neal Norwitz40d37812005-10-02 01:48:49 +0000335- Fix segfault with invalid coding.
336
337- SF bug #772896: unknown encoding results in MemoryError.
338
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000339- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000340 supported a __len__() method which evaluated to False when the iterator
341 was empty.
342
Guido van Rossum630db602005-09-20 18:49:54 +0000343- On 64-bit platforms, when __len__() returns a value that cannot be
344 represented as a C int, raise OverflowError.
345
Skip Montanarof8948ca2005-09-19 03:54:46 +0000346- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000347 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000348
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000349- SF bug #893549: parsing keyword arguments was broken with a few format
350 codes.
351
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000352- Changes donated by Elemental Security to make it work on AIX 5.3
353 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
354 bug #105470: test_pwd fails on 64bit system (Opteron).
355
Guido van Rossum539c6622005-09-14 17:49:54 +0000356- Changes donated by Elemental Security to make it work on HP-UX 11 on
357 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
358
Georg Brandl4550b8d2005-08-26 06:43:52 +0000359- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000360 (fixes bug #1119418).
361
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000362- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
363
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000364- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
365 exceptions that cause a function to exit.
366
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000367- The implementation of set() and frozenset() was revised to use its
368 own internal data structure. Memory consumption is reduced by 1/3
369 and there are modest speed-ups as well. The API is unchanged.
370
Tim Petersde7990b2005-07-17 23:45:23 +0000371- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
372
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000373- SF bug #1229429: PyObject_CallMethod failed to decrement some
374 reference counts in some error exit cases.
375
Tim Petersecc6e6a2005-07-10 22:30:55 +0000376- SF bug #1185883: Python's small-object memory allocator took over
377 a block managed by the platform C library whenever a realloc specified
378 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000379 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000380 portable way to copy data from the C-managed block into Python's
381 small-object space without risking a memory fault. Python's small-object
382 realloc now leaves such blocks under the control of the platform C
383 realloc.
384
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000385- SF bug #1232517: An overflow error was not detected properly when
386 attempting to convert a large float to an int in os.utime().
387
Raymond Hettinger3296e692005-06-29 23:29:56 +0000388- SF bug #1224347: hex longs now print with lowercase letters just
389 like their int counterparts.
390
Michael W. Hudson188d4362005-06-20 16:52:57 +0000391- SF bug #1163563: the original fix for bug #1010677 ("thread Module
392 Breaks PyGILState_Ensure()") broke badly in the case of multiple
393 interpreter states; back out that fix and do a better job (see
394 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
395 for a longer write-up of the problem).
396
Michael W. Hudsondf888462005-06-03 14:41:55 +0000397- SF patch #1180995: marshal now uses a binary format by default when
398 serializing floats.
399
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000400- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
401 the routines that promise to produce IEEE 754 binary representations
402 of floats now simply copy bytes around.
403
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000404- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
405 278.
406
Brett Cannonc3647ac2005-04-26 03:45:26 +0000407- patch #1109424: int, long, float, complex, and unicode now check for the
408 proper magic slot for type conversions when subclassed. Previously the
409 magic slot was ignored during conversion. Semantics now match the way
410 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000411 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000412 PyNumber_*().
413 Thanks Walter Dörwald.
414
Barry Warsawc8d907c2005-04-19 23:43:40 +0000415- Descriptors defined in C with a PyGetSetDef structure, where the setter is
416 NULL, now raise an AttributeError when attempting to set or delete the
417 attribute. Previously a TypeError was raised, but this was inconsistent
418 with the equivalent pure-Python implementation.
419
Michael W. Hudson774479c2005-04-18 08:46:17 +0000420- It is now safe to call PyGILState_Release() before
421 PyEval_InitThreads() (note that if there is reason to believe there
422 are multiple threads around you still must call PyEval_InitThreads()
423 before using the Python API; this fix is for extension modules that
424 have no way of knowing if Python is multi-threaded yet).
425
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000426- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
427 disabled caused a crash.
428
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000429- Bug #1165306: instancemethod_new allowed the creation of a method
430 with im_class == im_self == NULL, which caused a crash when called.
431
Tim Petersecc6e6a2005-07-10 22:30:55 +0000432- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000433 fixes the crash seen in bug #1165761
434
Raymond Hettinger96229b12005-03-11 06:49:40 +0000435- Added two new builtins, any() and all().
436
Brett Cannon409d8f22005-03-05 06:47:57 +0000437- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000438 (e.g., ``class C(): pass`` is no longer a syntax error).
439 Patch #1176012 added support to the 'parser' module and 'compiler' package
440 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000441
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000442- Patch #1115086: Support PY_LONGLONG in structmember.
443
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000444- Bug #1155938: new style classes did not check that __init__() was
445 returning None.
446
Tim Petersecc6e6a2005-07-10 22:30:55 +0000447- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000448 ('\') with a specific error message.
449
Martin v. Löwisff232d72005-03-03 09:24:38 +0000450- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
451
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000452- Bug #1124295: the __name__ attribute of file objects was
453 inadvertently made inaccessible in restricted mode.
454
Tim Petersecc6e6a2005-07-10 22:30:55 +0000455- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000456 an ferror() call.
457
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000458- min() and max() now support key= arguments with the same meaning as in
459 list.sort().
460
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000461- The peephole optimizer now performs simple constant folding in expressions:
462 (2+3) --> (5).
463
Raymond Hettingera422c342005-01-11 03:03:27 +0000464- set and frozenset objects can now be marshalled. SF #1098985.
465
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000466- Bug #1077106: Poor argument checking could cause memory corruption
467 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000468
Jeremy Hyltonab630502005-02-04 18:44:06 +0000469- The parser did not complain about future statements in illegal
470 positions. It once again reports a syntax error if a future
471 statement occurs after anything other than a doc string.
472
Neil Schemenauercf52c072005-08-12 17:34:58 +0000473- Change the %s format specifier for str objects so that it returns a
474 unicode instance if the argument is not an instance of basestring and
475 calling __str__ on the argument returns a unicode instance.
476
Tim Petersf4e69282006-02-27 17:15:31 +0000477- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
478 current thread state when the auto-GIL-state machinery knows about
479 it (since the thread state is being deleted, continuing to remember it
480 can't help, but can hurt if another thread happens to get created with
481 the same thread id).
482
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000483Extension Modules
484-----------------
485
Georg Brandl43f08a82006-03-31 18:01:16 +0000486- Patch #1380952: fix SSL objects timing out on consecutive read()s

500
501- The following modules were removed: regsub, reconvert, regex, regex_syntax.
502
503- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000504 is deprecated. The undocumented re.engine variable no longer exists.
505
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000506- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
507 SS2 (single-shift 2) escape sequences correctly.
508
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000509- The unicodedata module was updated to the 4.1 version of the Unicode
510 database. The 3.2 version is still available as unicodedata.db_3_2_0
511 for applications that require this specific version (such as IDNA).
512
Neal Norwitzb62c4332006-03-04 18:35:47 +0000513- The timing module is no longer built by default. It was deprecated
514 in PEP 4 in Python 2.0 or earlier.
515
Guido van Rossum1968ad32006-02-25 22:38:04 +0000516- Patch 1433928: Added a new type, defaultdict, to the collections module.
517 This uses the new __missing__ hook behavior added to dict (see above).
518
Georg Brandldbd83392006-02-20 09:42:33 +0000519- Bug #854823: socketmodule now builds on Sun platforms even when
520 INET_ADDRSTRLEN is not defined.
521
Georg Brandlf4f44152006-02-18 22:29:33 +0000522- Patch #1393157: os.startfile() now has an optional argument to specify
523 a "command verb" to invoke on the file.
524
Neal Norwitz082b2df2006-02-07 07:04:46 +0000525- Bug #876637, prevent stack corruption when socket descriptor
526 is larger than FD_SETSIZE.
527
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000528- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
529 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
530 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
531
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000532- Patch #1422385: The nis module now supports access to domains other
533 than the system default domain.
534
Martin v. Löwis14694662006-02-03 12:54:16 +0000535- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
536 are reported, the limit on path name lengths is removed, and stat reports
537 WindowsError now (instead of OSError).
538
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000539- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

614 the request code argument, which results in more C-like behaviour
615 for large or negative values.
616

Raymond Hettingerb2594052004-12-05 09:25:51 +0000660- itertools.islice() now accepts None for the start and step arguments.
661 This allows islice() to work more readily with slices:

681 in attribute values.
682
Anthony Baxterc51ee692006-04-01 00:57:31 +0000683- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000684 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000685 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000686 module will not be built.
687
Tim Petersc17976e2006-04-01 00:26:53 +0000688- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
689 aren't officially supported here, and trying to use them will probably
690 raise an exception some day. But dicts have been allowed, and "mostly
691 worked", so support for them won't go away without warning.
692
Georg Brandl338ef7d2006-03-31 18:42:16 +0000693- Bug #1445068: getpass.getpass() can now be given an explicit stream
694 argument to specify where to write the prompt.
695
Georg Brandl22ec80b2006-03-31 18:25:44 +0000696- Patch #1462313, bug #1443328: the pickle modules now can handle classes

702 key to be used for signing the uploaded code.
703
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000704- Queue.Queue objects now support .task_done() and .join() methods
705 to make it easier to monitor when daemon threads have completed
706 processing all enqueued tasks. Patch #1455676.
707

711
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000712- email 4.0 package now integrated. This is largely the same as the email 3.0
713 package that was included in Python 2.3, except that PEP 8 module names are
714 now used (e.g. mail.message instead of email.Message). The MIME classes
715 have been moved to a subpackage (e.g. email.mime.text instead of
716 email.MIMEText). The old names are still supported for now. Several
717 deprecated Message methods have been removed and lots of bugs have been
718 fixed. More details can be found in the email package documentation.
719
Walter Dörwald40108c92006-03-27 08:15:44 +0000720- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
721 (a subclass of tuple) that provides incremental decoders and encoders
722 (a way to use stateful codecs without the stream API). Python functions
723 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
724 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
725 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000726
Walter Dörwald067db482006-03-15 22:17:27 +0000727- Patch #1359365: Calling next() on a closed StringIO.String object raises
728 a ValueError instead of a StopIteration now (like file and cString.String do).
729 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
730 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000731

805 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
806 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
807 Ronald L. Rivest offered this advice for Python:
808
809 "The consensus of researchers in this area (at least as
810 expressed at the NIST Hash Function Workshop 10/31/05),
811 is that SHA-256 is a good choice for the time being, but
812 that research should continue, and other alternatives may
813 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000814
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000815- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl532efab2005-08-24 22:34:21 +0000860
Georg Brandlb9256022005-08-24 18:46:39 +0000861- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
862 ContentTooShortException, when the actually downloaded size does not
863 match the Content-Length header.
864
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +0000865- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
866
Martin v. Löwis56066d22005-08-24 07:38:12 +0000867- Bug #1178484: Return complete lines from codec stream readers
868 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000869 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +0000870

Georg Brandl5dbda752005-07-17 20:27:41 +0000882- Bug #1015140: disambiguated the term "article id" in nntplib docs and
883 docstrings to either "article number" or "message id".
884
Georg Brandla4a8b822005-07-15 09:13:21 +0000885- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
886 parameter, but uses the usual "kwargs=None".
887
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000888- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +0000889 Patch #1209527 (Contributed by Connelly).
890
Georg Brandl5c5fe2f2005-07-14 06:40:47 +0000891- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
892 to W3C name (404 -> 'Not Found'). RFE #1216944.
893
Georg Brandl9e43acf2005-07-04 17:16:07 +0000894- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,

906
Raymond Hettingerda99d1c2005-06-21 07:43:58 +0000907- The tokenize module now detects and reports indentation errors.
908 Bug #1224621.
909
Raymond Hettinger68c04532005-06-10 11:05:19 +0000910- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000911 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000912 the generate_tokens() function now accepts a callable argument that
913 terminates by raising StopIteration.
914
Georg Brandl9166e1a2005-06-04 09:20:03 +0000915- Bug #1196315: fix weakref.WeakValueDictionary constructor.

918 component of the path.
919
Skip Montanaro174dd222005-05-14 20:54:16 +0000920- Patch #1120353: The xmlrpclib module provides better, more transparent,
921 support for datetime.{datetime,date,time} objects. With use_datetime set
922 to True, applications shouldn't have to fiddle with the DateTime wrapper
923 class at all.
924
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000925- distutils.commands.upload was added to support uploading distribution
926 files to PyPI.
927
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000928- distutils.commands.register now encodes the data as UTF-8 before posting
929 them to PyPI.
930
Raymond Hettinger267b8682005-03-27 10:47:39 +0000931- decimal operator and comparison methods now return NotImplemented
932 instead of raising a TypeError when interacting with other types. This
933 allows other classes to implement __radd__ style methods and have them
934 work as expected.
935
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000936- Bug #1163325: Decimal infinities failed to hash. Attempting to
937 hash a NaN raised an InvalidOperation instead of a TypeError.
938
Tim Petersecc6e6a2005-07-10 22:30:55 +0000939- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +0000940 stream compression; add, for symmetry reasons, r:* as a synonym of r.
941

973
Guido van Rossumd0641422005-02-03 15:01:24 +0000974- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
975 disables recursive traversal through instance attributes, which can
976 be exploited in various ways.
977
Tim Peterse3547fd2005-12-16 23:13:57 +0000978- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000979 flags on the HTTP listening socket.
980
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000981- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
982 Fixed by reading the HTTP body in chunks instead of one big socket.read().
983
Tim Peterse3547fd2005-12-16 23:13:57 +0000984- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000985 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
986
Martin v. Löwis1d11de62005-01-29 13:29:23 +0000987- Bug #1110478: Revert os.environ.update to do putenv again.
988
Thomas Hellerd6c6e222005-01-20 19:20:16 +0000989- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
990
Martin v. Löwis22b457e2005-01-16 08:40:58 +0000991- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
992
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000993- Enhancements to the csv module:
994
995 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +0000996 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +0000997 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000998 + Dialect parameter parsing has been re-implemented to improve error
999 reporting.
1000 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1001 dictates.
1002 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001003 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001004 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001005 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1006 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001007 + reader now allows \r characters to be quoted (previously it only allowed
1008 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001009 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001010 + Dialect classes passed to the module are no longer instantiated by
1011 the module before being parsed (the former validation scheme required
1012 this, but the mechanism was unreliable).
1013 + The dialect registry now contains instances of the internal
1014 C-coded dialect type, rather than references to python objects.
1015 + the internal c-coded dialect type is now immutable.
1016 + register_dialect now accepts the same keyword dialect specifications
1017 as the reader and writer, allowing the user to register dialects
1018 without first creating a dialect class.
1019 + a configurable limit to the size of parsed fields has been added -
1020 previously, an unmatched quote character could result in the entire
1021 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001022 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001023 the parser field size limit (returning the former limit). The initial
1024 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001025 + A line_num attribute has been added to the reader object, which tracks
1026 the number of lines read from the source iterator. This is not
1027 the same as the number of records returned, as records can span
1028 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001029 + reader and writer objects were not being registered with the cyclic-GC.
1030 This has been fixed.
1031
Brett Cannone6539c42005-01-08 02:43:53 +00001032- _DummyThread objects in the threading module now delete self.__block that is
1033 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1034 lock primitives tend to be limited in number and thus should not be wasted on
1035 a _DummyThread object. Fixes bug #1089632.
1036
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001037- The imghdr module now detects Exif files.
1038
Raymond Hettinger6065d322004-12-20 23:51:53 +00001039- StringIO.truncate() now correctly adjusts the size attribute.
1040 (Bug #951915).
1041
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001042- locale.py now uses an updated locale alias table (built using
1043 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1044 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001045 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001046
Raymond Hettinger3557f422004-12-07 12:02:02 +00001047- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1048
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001049- the pickle module no longer accepts the deprecated None option in the
1050 args tuple returned by __reduce__().
1051
Brett Cannon84667c02004-12-07 03:25:18 +00001052- optparse now optionally imports gettext. This allows its use in setup.py.
1053
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001054- the pickle module no longer uses the deprecated bin parameter.
1055
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001056- the shelve module no longer uses the deprecated binary parameter.
1057
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001058- the pstats module no longer uses the deprecated ignore() method.
1059
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001060- the filecmp module no longer uses the deprecated use_statcache argument.
1061
Raymond Hettinger664347b2004-12-04 21:21:53 +00001062- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1063 extended or overridden by subclasses. Formerly, the subclassed method would
1064 be ignored by the rest of the module. (Bug #1078905).
1065
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001066- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001067 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001068
Walter Dörwald36733692004-12-22 12:50:50 +00001069- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1070 once when a size argument is given. This prevents a buffer overflow in the
1071 tokenizer with very long source lines.
1072
Barry Warsaw538561e2006-01-01 21:48:54 +00001073- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1074 immediately after creating the object, without any intervening
1075 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001076
Skip Montanaro05885812005-01-16 20:48:27 +00001077- The reconvert.quote function can now emit triple-quoted strings. The
1078 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001079
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001080- ``UserString.MutableString`` now supports negative indices in
1081 ``__setitem__`` and ``__delitem__``
1082
Greg Ward40407942005-03-05 02:53:17 +00001083- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1084 correctly.
1085
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001086- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1087 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1088 character even if the user has passed a size parameter to get a proper
1089 line ending. Remove the special handling of a "\r\n" that has been split
1090 between two lines.
1091
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001092- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1093 about illegal code points. The codec now supports PEP 293 style error
1094 handlers.
1095
Walter Dörwald78a78b02005-09-01 12:04:29 +00001096- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001097 from the input stream, so that the output is a byte string in the correct
1098 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001099
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001100- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1101 considering it exactly like a '*'.
1102
Walter Dörwald007f8df2005-10-09 19:42:27 +00001103- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1104 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001105
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001106- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1107
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001108- Patch #1413711: Certain patterns of differences were making difflib
1109 touch the recursion limit.
1110
Walter Dörwald58917a62006-03-31 15:26:22 +00001111- Bug #947906: An object oriented interface has been added to the calendar
1112 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001113 called as a script (e.g. via ``python -mcalendar``). Localized month and
1114 weekday names can be ouput (even if an exotic encoding is used) using

1118-----
1119
Neal Norwitz602d3392006-03-31 08:21:40 +00001120- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1121 by using -mieee gcc option.
1122

1124
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001125- Build support for Win64-AMD64 was added.
1126
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001127- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1128
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001129- Patch #881820: look for openpty and forkpty also in libbsd.
1130
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001131- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1132 The zlib module is now builtin on Windows.
1133
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001134- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1135
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001136- Bug #1189330: configure did not correctly determine the necessary
1137 value of LINKCC if python was built with GCC 4.0.
1138
Trent Mick8321b422005-07-26 02:29:21 +00001139- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1140 vulnerability in zlib 1.2.1 and 1.2.2.
1141
Brett Cannon08cd5982005-04-24 22:26:38 +00001142- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1143 flags that change binary compatibility. Changes were also made to
1144 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001145 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001146
Bob Ippolitoed233462005-03-29 13:47:59 +00001147- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1148 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1149 no longer exists). This configure patch makes things right.
1150
Martin v. Löwise2713be2005-03-08 15:03:08 +00001151- Bug #1158607: Build with --disable-unicode again.
1152
Brett Cannon46d96232005-02-16 00:07:19 +00001153- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1154 defined. Discovered as a result of not being able to build on OS X.
1155
Brett Cannon516592f2004-12-07 00:42:59 +00001156- setup.py now uses the directories specified in LDFLAGS using the -L option
1157 and in CPPFLAGS using the -I option for adding library and include
1158 directories, respectively, for compiling extension modules against. This has
1159 led to the core being compiled using the values in CPPFLAGS. It also removes
1160 the need for the special-casing of both DarwinPorts and Fink for darwin since
1161 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1162 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1163 Fink, ``-I/opt/local/include`` for DarwinPorts).
1164
Brett Cannon43802422005-02-10 20:48:03 +00001165- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1166 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1167 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1168 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001170C API
1171-----
1172
Tim Petersc9d78aa2006-03-26 23:27:58 +00001173- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1174 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1175 is obtained via the ``PyObject_`` family, it must be released via the
1176 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1177 always been officially true, but when Python's small-object allocator was
1178 introduced, an attempt was made to cater to a few extension modules
1179 discovered at the time that obtained memory via ``PyObject_New`` but
1180 released it via ``PyMem_DEL``. It's years later, and if such code still
1181 exists it will fail now (probably with segfaults, but calling wrong
1182 low-level memory management functions can yield many symptoms).
1183
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001184- Added a C API for set and frozenset objects.
1185
Raymond Hettinger66517482004-12-03 11:45:13 +00001186- Removed PyRange_New().
1187
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001188- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1189 mapping argument now. This string is used as a mapping table. Byte values
1190 greater than the length of the string and 0xFFFE are treated as undefined
1191 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001197- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001198
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001199- Patch #1276356: New resource "urlfetch" is implemented. This enables
1200 even impatient people to run tests that require remote files.
