12Core and builtins
13-----------------
14
Neal Norwitz1004a532006-05-15 07:17:23 +000015- Patch #1488312, Fix memory alignment problem on SPARC in unicode
16
Neal Norwitz373f0a72006-05-15 07:04:36 +000017- Bug #1487966: Fix SystemError with conditional expression in assignment
18
Martin v. Löwis879768d2006-05-11 13:28:43 +000019- WindowsError now has two error code attributes: errno, which carries
20 the error values from errno.h, and winerror, which carries the error
21 values from winerror.h. Previous versions put the winerror.h values
22 (from GetLastError()) into the errno attribute.
23
Martin v. Löwis77736712006-05-04 05:51:03 +000024- Patch #1475845: Raise IndentationError for unexpected indent.
25
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000026- Patch #1479181: split open() and file() from being aliases for each other.
27
Neal Norwitz7a5fc282006-05-15 06:48:14 +000028Extension Modules
29-----------------
30
Georg Brandl378d5922006-05-17 14:26:50 +000031- Patch #1490224: time.altzone is now set correctly on Cygwin.
32
Georg Brandl8d3342b2006-05-16 07:38:27 +000033- Patch #1435422: zlib's compress and decompress objects now have a
34 copy() method.
35
Neal Norwitz7a5fc282006-05-15 06:48:14 +000036- On Win32, os.listdir now supports arbitrarily-long Unicode path names
37 (up to the system limit of 32K characters).
38
39- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
40 As a result, these functions now raise WindowsError instead of OSError.
41
42- Calling Tk_Init twice is refused if the first call failed as that
43 may deadlock.
44
45Library
46-------
47
Georg Brandle3a25832006-05-17 14:56:04 +000048- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
49 and several features added, such as speed and geometry control.
50
Georg Brandl49c8f4c2006-05-15 19:30:35 +000051- Patch #1488881: add support for external file objects in bz2 compressed
52 tarfiles.
53
Neal Norwitz7a5fc282006-05-15 06:48:14 +000054- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
55 stdout arguments, making it possible to redirect input and output
56 for remote debugging.
57
58- Patch #1484695: Update the tarfile module to version 0.8. This fixes
59 a couple of issues, notably handling of long file names using the
60 GNU LONGNAME extension.
61
62- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
63 new flag when ``name`` is already the name of an option flag.
64
65- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
66 package.
67
68- Patch #1472854: make the rlcompleter.Completer class usable on non-
69 UNIX platforms.
70
71- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

90What's New in Python 2.5 alpha 2?
91=================================
92
93*Release date: 27-APR-2006*
94
95Core and builtins
96-----------------
97
Thomas Heller1b046642006-04-18 18:51:06 +000098- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
99 by converting these apis from macros into exported functions again:
100
101 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
102 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
103 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
104 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
105 PyRun_String Py_CompileString
106
Martin v. Löwis45294a92006-04-18 06:24:08 +0000107- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
108
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000109- All uses of PyStructSequence_InitType have been changed to initialize
110 the type objects only once, even if the interpreter is initialized
111 multiple times.
112
Neal Norwitz61546162006-04-14 05:20:28 +0000113- Bug #1454485, array.array('u') could crash the interpreter. This was
114 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
115 to unicode when it didn't make sense. 'u#' now requires a unicode string.
116
117- Py_UNICODE is unsigned. It was always documented as unsigned, but
118 due to a bug had a signed value in previous versions.
119
Tim Peters3a5e8b12006-04-11 01:44:07 +0000120- Patch #837242: ``id()`` of any Python object always gives a positive
121 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
122 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000123 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000124 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000125
Tim Peters3a5e8b12006-04-11 01:44:07 +0000126 def __hash__(self):
127 return id(self) # WRONG
128
129 because a hash result must be a (short) Python int but it was always
130 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000131 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000132 was always usable as a hash value before this patch. That's no longer
133 necessarily so.
134
135- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000136 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000137 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000138 #1454844)
139
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000140- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
141 involving generators that have paused outside of any ``try`` or ``with``
142 blocks. (In 2.5a1, a paused generator that was part of a reference
143 cycle could not be garbage collected, regardless of whether it was
144 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000146Extension Modules
147-----------------
148
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000149- Patch #1191065: Fix preprocessor problems on systems where recvfrom
150 is a macro.
151
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000152- Bug #1467952: os.listdir() now correctly raises an error if readdir()
153 fails with an error condition.
154
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000155- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
156
157- Bug #1117761: bsddb.*open() no longer raises an exception when using
158 the cachesize parameter.
159
160- Bug #1149413: bsddb.*open() no longer raises an exception when using
161 a temporary db (file=None) with the 'n' flag to truncate on open.
162
163- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
164 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000165
Armin Rigoa9017c32006-04-19 11:50:27 +0000166- Patch #1062014: AF_UNIX sockets under Linux have a special
167 abstract namespace that is now fully supported.
168
Anthony Baxter51bcb682006-04-05 14:51:42 +0000169Library
170-------
171
Tim Peters711bf302006-04-25 03:31:36 +0000172- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
173 a doctest to be skipped (the code is not run, and the expected output
174 or exception is ignored).
175
Nick Coghlanda2268f2006-04-24 04:37:15 +0000176- Fixed contextlib.nested to cope with exceptions being raised and
177 caught inside exit handlers.
178
Greg Wardab05edc2006-04-23 03:47:58 +0000179- Updated optparse module to Optik 1.5.1 (allow numeric constants in
180 hex, octal, or binary; add ``append_const`` action; keep going if
181 gettext cannot be imported; added ``OptionParser.destroy()`` method;
182 added ``epilog`` for better help generation).
183
Tim Peters21fbd572006-04-21 21:18:10 +0000184- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
185 called from a thread spawned as a side effect of importing a module.
186
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000187- The pydoc module now supports documenting packages contained in
188 .zip or .egg files.
189
190- The pkgutil module now has several new utility functions, such
191 as ``walk_packages()`` to support working with packages that are either
192 in the filesystem or zip files.
193
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000194- The mailbox module can now modify and delete messages from
195 mailboxes, in addition to simply reading them. Thanks to Gregory
196 K. Johnson for writing the code, and to the 2005 Google Summer of
197 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000198
Tim Petersc7605f22006-04-17 21:12:33 +0000199- The ``__del__`` method of class ``local`` in module ``_threading_local``
200 returned before accomplishing any of its intended cleanup.
201
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000202- Patch #790710: Add breakpoint command lists in pdb.
203
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000204- Patch #1063914: Add Tkinter.Misc.clipboard_get().
205
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000206- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
207
Anthony Baxtere29002c2006-04-12 12:07:31 +0000208- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
209 Windows. Bug #1469163.
210
Phillip J. Eby47032112006-04-11 01:07:43 +0000211- The warnings, linecache, inspect, traceback, site, and doctest modules
212 were updated to work correctly with modules imported from zipfiles or
213 via other PEP 302 __loader__ objects.
214
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000215- Patch #1467770: Reduce usage of subprocess._active to processes which
216 the application hasn't waited on.
217
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000218- Patch #1462222: Fix Tix.Grid.
219
Neal Norwitza31bf182006-04-09 03:35:43 +0000220- Fix exception when doing glob.glob('anything*/')
221
Skip Montanaro262fb922006-04-21 02:31:07 +0000222- The pstats.Stats class accepts an optional stream keyword argument to
223 direct output to an alternate file-like object.
224
Anthony Baxter51bcb682006-04-05 14:51:42 +0000225Build
226-----
227
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000228- The Makefile now has a reindent target, which runs reindent.py on
229 the library.
230
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000231- Patch #1470875: Building Python with MS Free Compiler
232
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000233- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000234
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000235- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
236 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000237 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000238 CXX from --with-cxx-main, see description in README.
239
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000240- Patch #1429775: Link extension modules with the shared libpython.
241
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000242- Fixed a libffi build problem on MIPS systems.
243
Tim Peters8931ff12006-05-13 23:28:20 +0000244- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
245 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
246 and "%zu" for unsigned integers of type ``size_t``.
247
Anthony Baxter51bcb682006-04-05 14:51:42 +0000248Tests
249-----
250
Nick Coghlanda2268f2006-04-24 04:37:15 +0000251- test_contextlib now checks contextlib.nested can cope with exceptions
252 being raised and caught inside exit handlers.
253
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000254- test_cmd_line now checks operation of the -m and -c command switches
255
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000256- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
257 it separately and by hand. It also wasn't cleaning up its changes to
258 the current Decimal context.
259
Thomas Woutersabd08882006-04-26 15:53:30 +0000260- regrtest.py now has a -M option to run tests that test the new limits of
261 containers, on 64-bit architectures. Running these tests is only sensible
262 on 64-bit machines with more than two gigabytes of memory. The argument
263 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +0000274- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
275
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000276- PEP 343: Added Context Types section to the library reference
277 and attempted to bring other PEP 343 related documentation into
278 line with the implementation and/or python-dev discussions.
279
Tim Peters8dc73d22006-04-24 02:03:16 +0000280- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000284What's New in Python 2.5 alpha 1?
285=================================
286
Anthony Baxterebed3f62006-04-03 15:03:44 +0000287*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000288
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000289Core and builtins
290-----------------
291
Nick Coghlan43832302006-04-23 17:04:07 +0000292- PEP 338: -m command line switch now delegates to runpy.run_module
293 allowing it to support modules in packages and zipfiles
294
Martin v. Löwisc661b882006-04-20 04:54:23 +0000295- On Windows, .DLL is not an accepted file name extension for
296 extension modules anymore; extensions are only found if they
297 end in .PYD.
298
Martin v. Löwisea62d252006-04-03 10:56:49 +0000299- Bug #1421664: sys.stderr.encoding is now set to the same value as
300 sys.stdout.encoding.
301
Neal Norwitz92e212f2006-04-03 04:48:37 +0000302- __import__ accepts keyword arguments.
303
Georg Brandlccadf842006-03-31 18:54:53 +0000304- Patch #1460496: round() now accepts keyword arguments.
305
Anthony Baxter262c00a2006-03-30 10:53:17 +0000306- Fixed bug #1459029 - unicode reprs were double-escaped.
307
Hye-Shik Changd478f342006-03-23 12:32:36 +0000308- Patch #1396919: The system scope threads are reenabled on FreeBSD
309 5.4 and later versions.
310
Neal Norwitze98ccf62006-03-23 05:39:47 +0000311- Bug #1115379: Compiling a Unicode string with an encoding declaration
312 now gives a SyntaxError.
313
Georg Brandlabd1ff82006-03-18 07:59:59 +0000314- Previously, Python code had no easy way to access the contents of a
315 cell object. Now, a ``cell_contents`` attribute has been added
316 (closes patch #1170323).
317
Tim Peterscf79aac2006-03-16 01:14:46 +0000318- Patch #1123430: Python's small-object allocator now returns an arena to
319 the system ``free()`` when all memory within an arena becomes unused
320 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
321 freed. Some applications will see a drop in virtual memory size now,
322 especially long-running applications that, from time to time, temporarily
323 use a large number of small objects. Note that when Python returns an
324 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000325 platform C library will in turn return that memory to the operating system.
326 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000327 appears to be effective at least on Microsoft C and gcc-based systems.
328 Thanks to Evan Jones for hard work and patience.
329
Georg Brandl533ff6f2006-03-08 18:09:27 +0000330- Patch #1434038: property() now uses the getter's docstring if there is
331 no "doc" argument given. This makes it possible to legitimately use
332 property() as a decorator to produce a read-only property.
333
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000334- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
335 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
336 of requiring an int or long in slicing and a few other contexts, enabling
337 other objects (e.g. Numeric Python's integers) to be used as slice indices.
338
Neal Norwitz995acdf2006-03-07 05:01:00 +0000339- Fixed various bugs reported by Coverity's Prevent tool.
340
Brett Cannonbf364092006-03-01 04:25:17 +0000341- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
342 new exception base class, BaseException, which has a new message attribute.
343 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
344 Raising a string exception now raises a DeprecationWarning.
345
Thomas Woutersfb609f42006-02-28 16:37:25 +0000346- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
347 explicitly relative, using 'from .module import name' to mean 'from the same
348 package as this module is in. Imports without dots still default to the
349 old relative-then-absolute, unless 'from __future__ import
350 absolute_import' is used.
351
Brett Cannona7446e32006-02-27 23:39:10 +0000352- Properly check if 'warnings' raises an exception (usually when a filter set
353 to "error" is triggered) when raising a warning for raising string
354 exceptions.
355
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000356- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000357 The name was removed from Include/code.h.
358
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000359- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000360
Guido van Rossum1968ad32006-02-25 22:38:04 +0000361- Patch 1433928:
362 - The copy module now "copies" function objects (as atomic objects).
363 - dict.__getitem__ now looks for a __missing__ hook before raising
364 KeyError.
365
Tim Peters84ef21c2006-02-28 20:39:06 +0000366- PEP 343: with statement implemented. Needs ``from __future__ import
367 with_statement``. Use of 'with' as a variable will generate a warning.
368 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000369 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000370 The following objects have __context__ methods:
371 - The built-in file type.
372 - The thread.LockType type.
373 - The following types defined by the threading module:
374 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
375 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000376
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000377- Fix the encodings package codec search function to only search
378 inside its own package. Fixes problem reported in patch #1433198.
379
380 Note: Codec packages should implement and register their own
381 codec search function. PEP 100 has the details.
382
Martin v. Löwis18e16552006-02-15 17:27:45 +0000383- PEP 353: Using ssize_t as the index type.
384
Neal Norwitzfc76d632006-01-10 06:03:13 +0000385- Patch #1400181, fix unicode string formatting to not use the locale.
386 This is how string objects work. u'%f' could use , instead of .
387 for the decimal point. Now both strings and unicode always use periods.
388
Neal Norwitz671b9e32006-01-09 07:07:12 +0000389- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
390 configure would break checking curses.h.
391
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000392- Bug #959576: The pwd module is now builtin. This allows Python to be
393 built on UNIX platforms without $HOME set.
394
Neal Norwitzc10978f2005-12-19 06:07:16 +0000395- Bug #1072182, fix some potential problems if characters are signed.
396
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000397- Bug #889500, fix line number on SyntaxWarning for global declarations.
398
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000399- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
400
Neal Norwitze7214a12005-12-18 05:03:17 +0000401- Support for converting hex strings to floats no longer works.
402 This was not portable. float('0x3') now raises a ValueError.
403
Barry Warsaw2a38a862005-12-18 01:27:35 +0000404- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000405 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000406 is now displayed in interactive prompt banner.
407
Georg Brandlfa166682005-12-17 21:45:17 +0000408- Implementation of PEP 341 - Unification of try/except and try/finally.
409 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000410 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000411
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000412- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
413 now encodes backslash correctly.
414
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000415- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
416
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000417- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000418 and long longs.
419
Neal Norwitz67715f02005-11-09 06:59:35 +0000420- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000421 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000422 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000423
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000424- Replaced most Unicode charmap codecs with new ones using the
425 new Unicode translate string feature in the builtin charmap
426 codec; the codecs were created from the mapping tables available
427 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
428 encodings now include a mapping for the Apple logo)
429
Tim Peterse3547fd2005-12-16 23:13:57 +0000430- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000431
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000432- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000433
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000434- A new AST parser implementation was completed. The abstract
435 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000436 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000437
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000438- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000439 The following code now raises a SyntaxError: foo(a = i for i in range(10))
440
Neal Norwitz708e51a2005-10-03 04:48:15 +0000441- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
442
Neal Norwitz11bd1192005-10-03 00:54:56 +0000443- SF Bug #887946: fix segfault when redirecting stdin from a directory.
444 Provide a warning when a directory is passed on the command line.
445
Neal Norwitz40d37812005-10-02 01:48:49 +0000446- Fix segfault with invalid coding.
447
448- SF bug #772896: unknown encoding results in MemoryError.
449
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000450- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000451 supported a __len__() method which evaluated to False when the iterator
452 was empty.
453
Guido van Rossum630db602005-09-20 18:49:54 +0000454- On 64-bit platforms, when __len__() returns a value that cannot be
455 represented as a C int, raise OverflowError.
456
Skip Montanarof8948ca2005-09-19 03:54:46 +0000457- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000458 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000459
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000460- SF bug #893549: parsing keyword arguments was broken with a few format
461 codes.
462
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000463- Changes donated by Elemental Security to make it work on AIX 5.3
464 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
465 bug #105470: test_pwd fails on 64bit system (Opteron).
466
Guido van Rossum539c6622005-09-14 17:49:54 +0000467- Changes donated by Elemental Security to make it work on HP-UX 11 on
468 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
469
Georg Brandl4550b8d2005-08-26 06:43:52 +0000470- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000471 (fixes bug #1119418).
472
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000473- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
474
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000475- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
476 exceptions that cause a function to exit.
477
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000478- The implementation of set() and frozenset() was revised to use its
479 own internal data structure. Memory consumption is reduced by 1/3
480 and there are modest speed-ups as well. The API is unchanged.
481
Tim Petersde7990b2005-07-17 23:45:23 +0000482- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
483
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000484- SF bug #1229429: PyObject_CallMethod failed to decrement some
485 reference counts in some error exit cases.
486
Tim Petersecc6e6a2005-07-10 22:30:55 +0000487- SF bug #1185883: Python's small-object memory allocator took over
488 a block managed by the platform C library whenever a realloc specified
489 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000490 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000491 portable way to copy data from the C-managed block into Python's
492 small-object space without risking a memory fault. Python's small-object
493 realloc now leaves such blocks under the control of the platform C
494 realloc.
495
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000496- SF bug #1232517: An overflow error was not detected properly when
497 attempting to convert a large float to an int in os.utime().
498
Raymond Hettinger3296e692005-06-29 23:29:56 +0000499- SF bug #1224347: hex longs now print with lowercase letters just
500 like their int counterparts.
501
Michael W. Hudson188d4362005-06-20 16:52:57 +0000502- SF bug #1163563: the original fix for bug #1010677 ("thread Module
503 Breaks PyGILState_Ensure()") broke badly in the case of multiple
504 interpreter states; back out that fix and do a better job (see
505 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
506 for a longer write-up of the problem).
507
Michael W. Hudsondf888462005-06-03 14:41:55 +0000508- SF patch #1180995: marshal now uses a binary format by default when
509 serializing floats.
510
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000511- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
512 the routines that promise to produce IEEE 754 binary representations
513 of floats now simply copy bytes around.
514
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000515- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
516 278.
517
Brett Cannonc3647ac2005-04-26 03:45:26 +0000518- patch #1109424: int, long, float, complex, and unicode now check for the
519 proper magic slot for type conversions when subclassed. Previously the
520 magic slot was ignored during conversion. Semantics now match the way
521 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000522 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000523 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000524 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000525
Barry Warsawc8d907c2005-04-19 23:43:40 +0000526- Descriptors defined in C with a PyGetSetDef structure, where the setter is
527 NULL, now raise an AttributeError when attempting to set or delete the
528 attribute. Previously a TypeError was raised, but this was inconsistent
529 with the equivalent pure-Python implementation.
530
Michael W. Hudson774479c2005-04-18 08:46:17 +0000531- It is now safe to call PyGILState_Release() before
532 PyEval_InitThreads() (note that if there is reason to believe there
533 are multiple threads around you still must call PyEval_InitThreads()
534 before using the Python API; this fix is for extension modules that
535 have no way of knowing if Python is multi-threaded yet).
536
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000537- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
538 disabled caused a crash.
539
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000540- Bug #1165306: instancemethod_new allowed the creation of a method
541 with im_class == im_self == NULL, which caused a crash when called.
542
Tim Petersecc6e6a2005-07-10 22:30:55 +0000543- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000544 fixes the crash seen in bug #1165761
545
Raymond Hettinger96229b12005-03-11 06:49:40 +0000546- Added two new builtins, any() and all().
547
Brett Cannon409d8f22005-03-05 06:47:57 +0000548- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000549 (e.g., ``class C(): pass`` is no longer a syntax error).
550 Patch #1176012 added support to the 'parser' module and 'compiler' package
551 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000552
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000553- Patch #1115086: Support PY_LONGLONG in structmember.
554
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000555- Bug #1155938: new style classes did not check that __init__() was
556 returning None.
557
Tim Petersecc6e6a2005-07-10 22:30:55 +0000558- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000559 ('\') with a specific error message.
560
Martin v. Löwisff232d72005-03-03 09:24:38 +0000561- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
562
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000563- Bug #1124295: the __name__ attribute of file objects was
564 inadvertently made inaccessible in restricted mode.
565
Tim Petersecc6e6a2005-07-10 22:30:55 +0000566- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000567 an ferror() call.
568
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000569- min() and max() now support key= arguments with the same meaning as in
570 list.sort().
571
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000572- The peephole optimizer now performs simple constant folding in expressions:
573 (2+3) --> (5).
574
Raymond Hettingera422c342005-01-11 03:03:27 +0000575- set and frozenset objects can now be marshalled. SF #1098985.
576
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000577- Bug #1077106: Poor argument checking could cause memory corruption
578 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000579
Jeremy Hyltonab630502005-02-04 18:44:06 +0000580- The parser did not complain about future statements in illegal
581 positions. It once again reports a syntax error if a future
582 statement occurs after anything other than a doc string.
583
Neil Schemenauercf52c072005-08-12 17:34:58 +0000584- Change the %s format specifier for str objects so that it returns a
585 unicode instance if the argument is not an instance of basestring and
586 calling __str__ on the argument returns a unicode instance.
587
Tim Petersf4e69282006-02-27 17:15:31 +0000588- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
589 current thread state when the auto-GIL-state machinery knows about
590 it (since the thread state is being deleted, continuing to remember it
591 can't help, but can hurt if another thread happens to get created with
592 the same thread id).
593

595-----------------
596
Georg Brandl43f08a82006-03-31 18:01:16 +0000597- Patch #1380952: fix SSL objects timing out on consecutive read()s
598
Neal Norwitz05a45592006-03-20 06:30:08 +0000599- Patch #1309579: wait3 and wait4 were added to the posix module.
600
Anthony Baxterfa869072006-03-20 05:21:58 +0000601- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
602 In addition, the existing ulaw code was updated.
603
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000604- RFE #567972: Socket objects' family, type and proto properties are

782-------
783
Nick Coghlan43832302006-04-23 17:04:07 +0000784- PEP 338: new module runpy defines a run_module function to support

Georg Brandl828fdef2006-04-01 08:59:03 +0000799 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000800 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000801 module will not be built.
802
Tim Petersc17976e2006-04-01 00:26:53 +0000803- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
804 aren't officially supported here, and trying to use them will probably
805 raise an exception some day. But dicts have been allowed, and "mostly
806 worked", so support for them won't go away without warning.
807
Georg Brandl338ef7d2006-03-31 18:42:16 +0000808- Bug #1445068: getpass.getpass() can now be given an explicit stream

826
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000827- email 4.0 package now integrated. This is largely the same as the email 3.0
828 package that was included in Python 2.3, except that PEP 8 module names are
829 now used (e.g. mail.message instead of email.Message). The MIME classes
830 have been moved to a subpackage (e.g. email.mime.text instead of
831 email.MIMEText). The old names are still supported for now. Several
832 deprecated Message methods have been removed and lots of bugs have been
833 fixed. More details can be found in the email package documentation.
834
Walter Dörwald40108c92006-03-27 08:15:44 +0000835- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
836 (a subclass of tuple) that provides incremental decoders and encoders
837 (a way to use stateful codecs without the stream API). Python functions
838 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
839 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
840 have been added.

843 a ValueError instead of a StopIteration now (like file and cString.String do).
844 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
845 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000846

Brett Cannon3cbd0382005-12-16 22:49:23 +0000918- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +0000919 SHA1, 224, 256, 384, and 512. Note that recent developments make the
920 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
921 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
922 Ronald L. Rivest offered this advice for Python:
923
924 "The consensus of researchers in this area (at least as
925 expressed at the NIST Hash Function Workshop 10/31/05),
926 is that SHA-256 is a good choice for the time being, but
927 that research should continue, and other alternatives may
928 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000929
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000930- Added a subset of Fredrik Lundh's ElementTree package. Available

Walter Dörwalda05834e2005-10-09 19:38:21 +0000984 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +0000985

1023 Bug #1224621.
1024
Raymond Hettinger68c04532005-06-10 11:05:19 +00001025- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001026 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001027 the generate_tokens() function now accepts a callable argument that
1028 terminates by raising StopIteration.
1029
Georg Brandl9166e1a2005-06-04 09:20:03 +00001030- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1049 work as expected.
1050
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001051- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00001089- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1090 disables recursive traversal through instance attributes, which can
1091 be exploited in various ways.
1092
Tim Peterse3547fd2005-12-16 23:13:57 +00001093- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001094 flags on the HTTP listening socket.
1095

1107
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001108- Enhancements to the csv module:
1109
1110 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001111 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001112 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001113 + Dialect parameter parsing has been re-implemented to improve error
1114 reporting.
1115 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1116 dictates.
1117 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001118 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001119 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001120 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1121 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001122 + reader now allows \r characters to be quoted (previously it only allowed
1123 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001124 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001125 + Dialect classes passed to the module are no longer instantiated by
1126 the module before being parsed (the former validation scheme required
1127 this, but the mechanism was unreliable).
1128 + The dialect registry now contains instances of the internal
1129 C-coded dialect type, rather than references to python objects.
1130 + the internal c-coded dialect type is now immutable.
1131 + register_dialect now accepts the same keyword dialect specifications
1132 as the reader and writer, allowing the user to register dialects
1133 without first creating a dialect class.
1134 + a configurable limit to the size of parsed fields has been added -
1135 previously, an unmatched quote character could result in the entire
1136 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001137 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001138 the parser field size limit (returning the former limit). The initial
1139 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001140 + A line_num attribute has been added to the reader object, which tracks
1141 the number of lines read from the source iterator. This is not
1142 the same as the number of records returned, as records can span
1143 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001144 + reader and writer objects were not being registered with the cyclic-GC.
1145 This has been fixed.
1146
Brett Cannone6539c42005-01-08 02:43:53 +00001147- _DummyThread objects in the threading module now delete self.__block that is
1148 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1149 lock primitives tend to be limited in number and thus should not be wasted on
1150 a _DummyThread object. Fixes bug #1089632.
1151
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001152- The imghdr module now detects Exif files.
1153
Raymond Hettinger6065d322004-12-20 23:51:53 +00001154- StringIO.truncate() now correctly adjusts the size attribute.
1155 (Bug #951915).
1156
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001157- locale.py now uses an updated locale alias table (built using
1158 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1159 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001160 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001161
Raymond Hettinger3557f422004-12-07 12:02:02 +00001162- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1163
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001164- the pickle module no longer accepts the deprecated None option in the
1165 args tuple returned by __reduce__().
1166
Brett Cannon84667c02004-12-07 03:25:18 +00001167- optparse now optionally imports gettext. This allows its use in setup.py.
1168
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001169- the pickle module no longer uses the deprecated bin parameter.
1170
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001171- the shelve module no longer uses the deprecated binary parameter.
1172

1174
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001175- the filecmp module no longer uses the deprecated use_statcache argument.
1176
Raymond Hettinger664347b2004-12-04 21:21:53 +00001177- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1178 extended or overridden by subclasses. Formerly, the subclassed method would
1179 be ignored by the rest of the module. (Bug #1078905).
1180
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001181- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001182 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001183
Walter Dörwald36733692004-12-22 12:50:50 +00001184- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1185 once when a size argument is given. This prevents a buffer overflow in the
1186 tokenizer with very long source lines.
1187
Barry Warsaw538561e2006-01-01 21:48:54 +00001188- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1189 immediately after creating the object, without any intervening
1190 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001191
Skip Montanaro05885812005-01-16 20:48:27 +00001192- The reconvert.quote function can now emit triple-quoted strings. The
1193 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001194
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001195- ``UserString.MutableString`` now supports negative indices in
1196 ``__setitem__`` and ``__delitem__``
1197
Greg Ward40407942005-03-05 02:53:17 +00001198- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1199 correctly.
1200
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001201- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1202 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1203 character even if the user has passed a size parameter to get a proper
1204 line ending. Remove the special handling of a "\r\n" that has been split
1205 between two lines.
1206
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001207- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1208 about illegal code points. The codec now supports PEP 293 style error
1209 handlers.
1210
Walter Dörwald78a78b02005-09-01 12:04:29 +00001211- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001212 from the input stream, so that the output is a byte string in the correct
1213 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001214
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001215- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1216 considering it exactly like a '*'.
1217
Walter Dörwald007f8df2005-10-09 19:42:27 +00001218- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1219 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001220
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001221- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1222
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001223- Patch #1413711: Certain patterns of differences were making difflib
1224 touch the recursion limit.
1225
Walter Dörwald58917a62006-03-31 15:26:22 +00001226- Bug #947906: An object oriented interface has been added to the calendar
1227 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001228 called as a script (e.g. via ``python -mcalendar``). Localized month and
1229 weekday names can be ouput (even if an exotic encoding is used) using
1230 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001231
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001232Build
1233-----
1234
Neal Norwitz602d3392006-03-31 08:21:40 +00001235- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1236 by using -mieee gcc option.
1237
Martin v. Löwis86d66262006-02-17 08:40:11 +00001238- Patch #1432345: Make python compile on DragonFly.
1239
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001240- Build support for Win64-AMD64 was added.
1241
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001242- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1243
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001244- Patch #881820: look for openpty and forkpty also in libbsd.
1245
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001246- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1247 The zlib module is now builtin on Windows.
1248
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001249- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1250
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001251- Bug #1189330: configure did not correctly determine the necessary
1252 value of LINKCC if python was built with GCC 4.0.
1253
Trent Mick8321b422005-07-26 02:29:21 +00001254- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1255 vulnerability in zlib 1.2.1 and 1.2.2.
1256
Brett Cannon08cd5982005-04-24 22:26:38 +00001257- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1258 flags that change binary compatibility. Changes were also made to
1259 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001260 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001261
Bob Ippolitoed233462005-03-29 13:47:59 +00001262- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1263 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1264 no longer exists). This configure patch makes things right.
1265
Martin v. Löwise2713be2005-03-08 15:03:08 +00001266- Bug #1158607: Build with --disable-unicode again.
1267
Brett Cannon46d96232005-02-16 00:07:19 +00001268- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1269 defined. Discovered as a result of not being able to build on OS X.
1270
Brett Cannon516592f2004-12-07 00:42:59 +00001271- setup.py now uses the directories specified in LDFLAGS using the -L option
1272 and in CPPFLAGS using the -I option for adding library and include
1273 directories, respectively, for compiling extension modules against. This has
1274 led to the core being compiled using the values in CPPFLAGS. It also removes
1275 the need for the special-casing of both DarwinPorts and Fink for darwin since
1276 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1277 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1278 Fink, ``-I/opt/local/include`` for DarwinPorts).
1279
Brett Cannon43802422005-02-10 20:48:03 +00001280- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1281 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1282 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1283 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001285C API
1286-----
1287
Tim Petersc9d78aa2006-03-26 23:27:58 +00001288- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1289 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1290 is obtained via the ``PyObject_`` family, it must be released via the
1291 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1292 always been officially true, but when Python's small-object allocator was
1293 introduced, an attempt was made to cater to a few extension modules
1294 discovered at the time that obtained memory via ``PyObject_New`` but
1295 released it via ``PyMem_DEL``. It's years later, and if such code still
1296 exists it will fail now (probably with segfaults, but calling wrong
1297 low-level memory management functions can yield many symptoms).
1298
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001299- Added a C API for set and frozenset objects.
1300
Raymond Hettinger66517482004-12-03 11:45:13 +00001301- Removed PyRange_New().
1302
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001303- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1304 mapping argument now. This string is used as a mapping table. Byte values
1305 greater than the length of the string and 0xFFFE are treated as undefined
1306 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001313
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001314- Patch #1276356: New resource "urlfetch" is implemented. This enables
1315 even impatient people to run tests that require remote files.

1366 vimrc to it (was previous up a level).
1367
Georg Brandl56897312005-08-24 18:32:30 +00001368- Added two new files to Tools/scripts: pysource.py, which recursively
