Nick Coghlanc649ec52006-05-29 12:43:05 +00007What's New in Python 2.5 beta 1?
Anthony Baxter51bcb682006-04-05 14:51:42 +00008=================================
9
Nick Coghlanc649ec52006-05-29 12:43:05 +000010*Release date: XX-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Georg Brandlb7c8f542006-05-27 12:30:25 +000015- Builtin exceptions are now full-blown new-style classes instead of
16 instances pretending to be classes, which speeds up exception handling
17 by about 80% in comparison to 2.5a2.
18
Martin v. Löwisd004fc82006-05-27 08:36:52 +000019- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
20 Unicode 4.1.
21
Georg Brandlf4ef1162006-05-26 18:03:31 +000022- Patch #921466: sys.path_importer_cache is now used to cache valid and
23 invalid file paths for the built-in import machinery which leads to
24 fewer open calls on startup.
25
Tim Peters696cf432006-05-24 21:10:40 +000026- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
27 of-2 bases. The largest speedup is for inputs with about 1000 decimal
28 digits. Conversion from non-power-of-2 bases remains quadratic-time in
29 the number of input digits (it was and remains linear-time for bases
30 2, 4, 8, 16 and 32).
31
Tim Petersb713ec22006-05-23 18:45:30 +000032- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
33 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
34 an integer close to ``sys.maxint``. This was repaired by patch
35 #1335972, which also gives a nice speedup.
36
Richard Jonescebbefc2006-05-23 18:28:17 +000037- Patch #1337051: reduced size of frame objects.
38
39- PyErr_NewException now accepts a tuple of base classes as its
40 "base" parameter.
41
Richard Jones7c88dcc2006-05-23 10:37:38 +000042- Patch #876206: function call speedup by retaining allocated frame
43 objects.
44
Georg Brandl7b90e162006-05-18 07:01:27 +000045- Bug #1462152: file() now checks more thoroughly for invalid mode
46 strings and removes a possible "U" before passing the mode to the
47 C library function.
48
Neal Norwitz1004a532006-05-15 07:17:23 +000049- Patch #1488312, Fix memory alignment problem on SPARC in unicode
50
Neal Norwitz373f0a72006-05-15 07:04:36 +000051- Bug #1487966: Fix SystemError with conditional expression in assignment
52
Martin v. Löwis879768d2006-05-11 13:28:43 +000053- WindowsError now has two error code attributes: errno, which carries
54 the error values from errno.h, and winerror, which carries the error
55 values from winerror.h. Previous versions put the winerror.h values
56 (from GetLastError()) into the errno attribute.
57
Martin v. Löwis77736712006-05-04 05:51:03 +000058- Patch #1475845: Raise IndentationError for unexpected indent.
59
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000060- Patch #1479181: split open() and file() from being aliases for each other.
61
Neal Norwitz7a5fc282006-05-15 06:48:14 +000062Extension Modules
63-----------------
64
Nick Coghlanc649ec52006-05-29 12:43:05 +000065- Patch #1478788 (modified version): The functional extension module has
66 been renamed to _functools and a functools Python wrapper module added.
67 This provides a home for additional function related utilities that are
68 not specifically about functional programming. See PEP 309.
69
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000070- Patch #1493701: performance enhancements for struct module.
71
Georg Brandl378d5922006-05-17 14:26:50 +000072- Patch #1490224: time.altzone is now set correctly on Cygwin.
73
Georg Brandl8d3342b2006-05-16 07:38:27 +000074- Patch #1435422: zlib's compress and decompress objects now have a
75 copy() method.
76
Neal Norwitz7a5fc282006-05-15 06:48:14 +000077- On Win32, os.listdir now supports arbitrarily-long Unicode path names
78 (up to the system limit of 32K characters).
79
80- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
81 As a result, these functions now raise WindowsError instead of OSError.
82
Tim Peters7a822da2006-05-25 21:50:17 +000083- ``time.clock()`` on Win64 should use the high-performance Windows
84 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
85 Windows platforms).
86
Neal Norwitz7a5fc282006-05-15 06:48:14 +000087- Calling Tk_Init twice is refused if the first call failed as that
88 may deadlock.
89
Nick Coghlanc649ec52006-05-29 12:43:05 +000090
Neal Norwitz7a5fc282006-05-15 06:48:14 +000091Library
92-------
93
Georg Brandlfd9a4b12006-05-29 20:57:01 +000094- Patch #1497027: try HTTP digest auth before basic auth in urllib2
95 (thanks for J. J. Lee).
96
Georg Brandl2b330372006-05-28 20:23:12 +000097- Patch #1496206: improve urllib2 handling of passwords with respect to
98 default HTTP and HTTPS ports.
99
George Yoshidaf3c65de2006-05-28 16:39:09 +0000100- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
101
Bob Ippolito7298f272006-05-23 18:43:47 +0000102- Patch #1281707: speed up gzip.readline.
103
Georg Brandlb89316f2006-05-17 15:51:16 +0000104- Patch #1180296: Two new functions were added to the locale module:
105 format_string() to get the effect of "format % items" but locale-aware,
106 and currency() to format a monetary number with currency sign.
107
Georg Brandle3a25832006-05-17 14:56:04 +0000108- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
109 and several features added, such as speed and geometry control.
110
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000111- Patch #1488881: add support for external file objects in bz2 compressed
112 tarfiles.
113
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000114- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
115 stdout arguments, making it possible to redirect input and output
116 for remote debugging.
117
118- Patch #1484695: Update the tarfile module to version 0.8. This fixes
119 a couple of issues, notably handling of long file names using the
120 GNU LONGNAME extension.
121
122- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
123 new flag when ``name`` is already the name of an option flag.
124
125- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
126 package.
127
128- Patch #1472854: make the rlcompleter.Completer class usable on non-
129 UNIX platforms.
130
131- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000156What's New in Python 2.5 alpha 2?
157=================================
158
159*Release date: 27-APR-2006*
160
161Core and builtins
162-----------------
163
Thomas Heller1b046642006-04-18 18:51:06 +0000164- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
165 by converting these apis from macros into exported functions again:
166
167 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
168 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
169 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
170 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
171 PyRun_String Py_CompileString
172
Martin v. Löwis45294a92006-04-18 06:24:08 +0000173- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
174
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000175- All uses of PyStructSequence_InitType have been changed to initialize
176 the type objects only once, even if the interpreter is initialized
177 multiple times.
178
Neal Norwitz61546162006-04-14 05:20:28 +0000179- Bug #1454485, array.array('u') could crash the interpreter. This was
180 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
181 to unicode when it didn't make sense. 'u#' now requires a unicode string.
182
183- Py_UNICODE is unsigned. It was always documented as unsigned, but
184 due to a bug had a signed value in previous versions.
185
Tim Peters3a5e8b12006-04-11 01:44:07 +0000186- Patch #837242: ``id()`` of any Python object always gives a positive
187 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
188 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000189 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000190 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000191
Tim Peters3a5e8b12006-04-11 01:44:07 +0000192 def __hash__(self):
193 return id(self) # WRONG
194
195 because a hash result must be a (short) Python int but it was always
196 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000197 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000198 was always usable as a hash value before this patch. That's no longer
199 necessarily so.
200
201- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000202 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000203 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000204 #1454844)
205
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000206- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
207 involving generators that have paused outside of any ``try`` or ``with``
208 blocks. (In 2.5a1, a paused generator that was part of a reference
209 cycle could not be garbage collected, regardless of whether it was
210 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000212Extension Modules
213-----------------
214
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000215- Patch #1191065: Fix preprocessor problems on systems where recvfrom
216 is a macro.
217
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000218- Bug #1467952: os.listdir() now correctly raises an error if readdir()
219 fails with an error condition.
220
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000221- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
222
223- Bug #1117761: bsddb.*open() no longer raises an exception when using
224 the cachesize parameter.
225
226- Bug #1149413: bsddb.*open() no longer raises an exception when using
227 a temporary db (file=None) with the 'n' flag to truncate on open.
228
229- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
230 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000231
Armin Rigoa9017c32006-04-19 11:50:27 +0000232- Patch #1062014: AF_UNIX sockets under Linux have a special
233 abstract namespace that is now fully supported.
234
Anthony Baxter51bcb682006-04-05 14:51:42 +0000235Library
236-------
237
Tim Peters711bf302006-04-25 03:31:36 +0000238- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
239 a doctest to be skipped (the code is not run, and the expected output
240 or exception is ignored).
241
Nick Coghlanda2268f2006-04-24 04:37:15 +0000242- Fixed contextlib.nested to cope with exceptions being raised and
243 caught inside exit handlers.
244
Greg Wardab05edc2006-04-23 03:47:58 +0000245- Updated optparse module to Optik 1.5.1 (allow numeric constants in
246 hex, octal, or binary; add ``append_const`` action; keep going if
247 gettext cannot be imported; added ``OptionParser.destroy()`` method;
248 added ``epilog`` for better help generation).
249
Tim Peters21fbd572006-04-21 21:18:10 +0000250- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
251 called from a thread spawned as a side effect of importing a module.
252
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000253- The pydoc module now supports documenting packages contained in
254 .zip or .egg files.
255
256- The pkgutil module now has several new utility functions, such
257 as ``walk_packages()`` to support working with packages that are either
258 in the filesystem or zip files.
259
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000260- The mailbox module can now modify and delete messages from
261 mailboxes, in addition to simply reading them. Thanks to Gregory
262 K. Johnson for writing the code, and to the 2005 Google Summer of
263 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000264
Tim Petersc7605f22006-04-17 21:12:33 +0000265- The ``__del__`` method of class ``local`` in module ``_threading_local``
266 returned before accomplishing any of its intended cleanup.
267
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000268- Patch #790710: Add breakpoint command lists in pdb.
269
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000270- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000272- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
273
Anthony Baxtere29002c2006-04-12 12:07:31 +0000274- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
275 Windows. Bug #1469163.
276
Phillip J. Eby47032112006-04-11 01:07:43 +0000277- The warnings, linecache, inspect, traceback, site, and doctest modules
278 were updated to work correctly with modules imported from zipfiles or
279 via other PEP 302 __loader__ objects.
280
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000281- Patch #1467770: Reduce usage of subprocess._active to processes which

293
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000294- The Makefile now has a reindent target, which runs reindent.py on
295 the library.

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000301- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
302 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000303 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000304 CXX from --with-cxx-main, see description in README.
305
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000306- Patch #1429775: Link extension modules with the shared libpython.
307
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000308- Fixed a libffi build problem on MIPS systems.
309
Tim Peters8931ff12006-05-13 23:28:20 +0000310- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
311 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

316
Nick Coghlanda2268f2006-04-24 04:37:15 +0000317- test_contextlib now checks contextlib.nested can cope with exceptions
318 being raised and caught inside exit handlers.
319
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000320- test_cmd_line now checks operation of the -m and -c command switches
321
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000322- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
323 it separately and by hand. It also wasn't cleaning up its changes to
324 the current Decimal context.
325
Thomas Woutersabd08882006-04-26 15:53:30 +0000326- regrtest.py now has a -M option to run tests that test the new limits of
327 containers, on 64-bit architectures. Running these tests is only sensible
328 on 64-bit machines with more than two gigabytes of memory. The argument
329 passed is the maximum amount of memory for the tests to use.

338-------------
339
Tim Petersb06d28c2006-05-12 01:57:59 +0000340- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
341
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000342- PEP 343: Added Context Types section to the library reference
343 and attempted to bring other PEP 343 related documentation into
344 line with the implementation and/or python-dev discussions.
345
Tim Peters8dc73d22006-04-24 02:03:16 +0000346- Bug #1337990: clarified that ``doctest`` does not support examples
347 requiring both expected output and an exception.

Anthony Baxterebed3f62006-04-03 15:03:44 +0000353*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000354
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000355Core and builtins
356-----------------
357
Nick Coghlan43832302006-04-23 17:04:07 +0000358- PEP 338: -m command line switch now delegates to runpy.run_module
359 allowing it to support modules in packages and zipfiles
360
Martin v. Löwisc661b882006-04-20 04:54:23 +0000361- On Windows, .DLL is not an accepted file name extension for
362 extension modules anymore; extensions are only found if they
363 end in .PYD.
364
Martin v. Löwisea62d252006-04-03 10:56:49 +0000365- Bug #1421664: sys.stderr.encoding is now set to the same value as
366 sys.stdout.encoding.
367
Neal Norwitz92e212f2006-04-03 04:48:37 +0000368- __import__ accepts keyword arguments.
369
Georg Brandlccadf842006-03-31 18:54:53 +0000370- Patch #1460496: round() now accepts keyword arguments.
371
Anthony Baxter262c00a2006-03-30 10:53:17 +0000372- Fixed bug #1459029 - unicode reprs were double-escaped.
373
Hye-Shik Changd478f342006-03-23 12:32:36 +0000374- Patch #1396919: The system scope threads are reenabled on FreeBSD
375 5.4 and later versions.
376
Neal Norwitze98ccf62006-03-23 05:39:47 +0000377- Bug #1115379: Compiling a Unicode string with an encoding declaration
378 now gives a SyntaxError.
379
Georg Brandlabd1ff82006-03-18 07:59:59 +0000380- Previously, Python code had no easy way to access the contents of a
381 cell object. Now, a ``cell_contents`` attribute has been added
382 (closes patch #1170323).
383
Tim Peterscf79aac2006-03-16 01:14:46 +0000384- Patch #1123430: Python's small-object allocator now returns an arena to
385 the system ``free()`` when all memory within an arena becomes unused
386 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
387 freed. Some applications will see a drop in virtual memory size now,
388 especially long-running applications that, from time to time, temporarily
389 use a large number of small objects. Note that when Python returns an
390 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000391 platform C library will in turn return that memory to the operating system.
392 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000393 appears to be effective at least on Microsoft C and gcc-based systems.
394 Thanks to Evan Jones for hard work and patience.
395
Georg Brandl533ff6f2006-03-08 18:09:27 +0000396- Patch #1434038: property() now uses the getter's docstring if there is
397 no "doc" argument given. This makes it possible to legitimately use
398 property() as a decorator to produce a read-only property.
399
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000400- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
401 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
402 of requiring an int or long in slicing and a few other contexts, enabling
403 other objects (e.g. Numeric Python's integers) to be used as slice indices.
404
Neal Norwitz995acdf2006-03-07 05:01:00 +0000405- Fixed various bugs reported by Coverity's Prevent tool.
406
Brett Cannonbf364092006-03-01 04:25:17 +0000407- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
408 new exception base class, BaseException, which has a new message attribute.
409 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
410 Raising a string exception now raises a DeprecationWarning.
411
Thomas Woutersfb609f42006-02-28 16:37:25 +0000412- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
413 explicitly relative, using 'from .module import name' to mean 'from the same
414 package as this module is in. Imports without dots still default to the
415 old relative-then-absolute, unless 'from __future__ import
416 absolute_import' is used.
417
Brett Cannona7446e32006-02-27 23:39:10 +0000418- Properly check if 'warnings' raises an exception (usually when a filter set
419 to "error" is triggered) when raising a warning for raising string
420 exceptions.
421
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000422- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000423 The name was removed from Include/code.h.
424
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000425- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000426
Guido van Rossum1968ad32006-02-25 22:38:04 +0000427- Patch 1433928:
428 - The copy module now "copies" function objects (as atomic objects).
429 - dict.__getitem__ now looks for a __missing__ hook before raising
430 KeyError.
431
Tim Peters84ef21c2006-02-28 20:39:06 +0000432- PEP 343: with statement implemented. Needs ``from __future__ import
433 with_statement``. Use of 'with' as a variable will generate a warning.
434 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000435 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000436 The following objects have __context__ methods:
437 - The built-in file type.
438 - The thread.LockType type.
439 - The following types defined by the threading module:
440 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
441 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000442
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000443- Fix the encodings package codec search function to only search
444 inside its own package. Fixes problem reported in patch #1433198.
445
446 Note: Codec packages should implement and register their own
447 codec search function. PEP 100 has the details.
448
Martin v. Löwis18e16552006-02-15 17:27:45 +0000449- PEP 353: Using ssize_t as the index type.
450
Neal Norwitzfc76d632006-01-10 06:03:13 +0000451- Patch #1400181, fix unicode string formatting to not use the locale.
452 This is how string objects work. u'%f' could use , instead of .
453 for the decimal point. Now both strings and unicode always use periods.
454
Neal Norwitz671b9e32006-01-09 07:07:12 +0000455- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
456 configure would break checking curses.h.
457
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000458- Bug #959576: The pwd module is now builtin. This allows Python to be
459 built on UNIX platforms without $HOME set.
460
Neal Norwitzc10978f2005-12-19 06:07:16 +0000461- Bug #1072182, fix some potential problems if characters are signed.
462
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000463- Bug #889500, fix line number on SyntaxWarning for global declarations.
464
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000465- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
466
Neal Norwitze7214a12005-12-18 05:03:17 +0000467- Support for converting hex strings to floats no longer works.
468 This was not portable. float('0x3') now raises a ValueError.
469
Barry Warsaw2a38a862005-12-18 01:27:35 +0000470- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000471 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000472 is now displayed in interactive prompt banner.
473
Georg Brandlfa166682005-12-17 21:45:17 +0000474- Implementation of PEP 341 - Unification of try/except and try/finally.
475 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000476 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000477
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000478- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
479 now encodes backslash correctly.
480
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000481- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
482
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000483- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000484 and long longs.
485
Neal Norwitz67715f02005-11-09 06:59:35 +0000486- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000487 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000488 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000489
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000490- Replaced most Unicode charmap codecs with new ones using the
491 new Unicode translate string feature in the builtin charmap
492 codec; the codecs were created from the mapping tables available
493 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
494 encodings now include a mapping for the Apple logo)
495
Tim Peterse3547fd2005-12-16 23:13:57 +0000496- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000497
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000498- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000499
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000500- A new AST parser implementation was completed. The abstract
501 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000502 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000503
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000504- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000505 The following code now raises a SyntaxError: foo(a = i for i in range(10))
506
Neal Norwitz708e51a2005-10-03 04:48:15 +0000507- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
508
Neal Norwitz11bd1192005-10-03 00:54:56 +0000509- SF Bug #887946: fix segfault when redirecting stdin from a directory.
510 Provide a warning when a directory is passed on the command line.
511
Neal Norwitz40d37812005-10-02 01:48:49 +0000512- Fix segfault with invalid coding.
513
514- SF bug #772896: unknown encoding results in MemoryError.
515
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000516- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000517 supported a __len__() method which evaluated to False when the iterator
518 was empty.
519
Guido van Rossum630db602005-09-20 18:49:54 +0000520- On 64-bit platforms, when __len__() returns a value that cannot be
521 represented as a C int, raise OverflowError.
522
Skip Montanarof8948ca2005-09-19 03:54:46 +0000523- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000524 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000525
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000526- SF bug #893549: parsing keyword arguments was broken with a few format
527 codes.
528
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000529- Changes donated by Elemental Security to make it work on AIX 5.3
530 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
531 bug #105470: test_pwd fails on 64bit system (Opteron).
532
Guido van Rossum539c6622005-09-14 17:49:54 +0000533- Changes donated by Elemental Security to make it work on HP-UX 11 on
534 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
535
Georg Brandl4550b8d2005-08-26 06:43:52 +0000536- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000537 (fixes bug #1119418).
538
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000539- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
540
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000541- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
542 exceptions that cause a function to exit.
543
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000544- The implementation of set() and frozenset() was revised to use its
545 own internal data structure. Memory consumption is reduced by 1/3
546 and there are modest speed-ups as well. The API is unchanged.
547
Tim Petersde7990b2005-07-17 23:45:23 +0000548- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
549
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000550- SF bug #1229429: PyObject_CallMethod failed to decrement some
551 reference counts in some error exit cases.
552
Tim Petersecc6e6a2005-07-10 22:30:55 +0000553- SF bug #1185883: Python's small-object memory allocator took over
554 a block managed by the platform C library whenever a realloc specified
555 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000556 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000557 portable way to copy data from the C-managed block into Python's
558 small-object space without risking a memory fault. Python's small-object
559 realloc now leaves such blocks under the control of the platform C
560 realloc.
561
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000562- SF bug #1232517: An overflow error was not detected properly when
563 attempting to convert a large float to an int in os.utime().
564
Raymond Hettinger3296e692005-06-29 23:29:56 +0000565- SF bug #1224347: hex longs now print with lowercase letters just
566 like their int counterparts.
567
Michael W. Hudson188d4362005-06-20 16:52:57 +0000568- SF bug #1163563: the original fix for bug #1010677 ("thread Module
569 Breaks PyGILState_Ensure()") broke badly in the case of multiple
570 interpreter states; back out that fix and do a better job (see
571 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
572 for a longer write-up of the problem).
573
Michael W. Hudsondf888462005-06-03 14:41:55 +0000574- SF patch #1180995: marshal now uses a binary format by default when
575 serializing floats.
576
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000577- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
578 the routines that promise to produce IEEE 754 binary representations
579 of floats now simply copy bytes around.
580
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000581- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
582 278.
583
Brett Cannonc3647ac2005-04-26 03:45:26 +0000584- patch #1109424: int, long, float, complex, and unicode now check for the
585 proper magic slot for type conversions when subclassed. Previously the
586 magic slot was ignored during conversion. Semantics now match the way
587 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000588 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000589 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000590 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000591
Barry Warsawc8d907c2005-04-19 23:43:40 +0000592- Descriptors defined in C with a PyGetSetDef structure, where the setter is
593 NULL, now raise an AttributeError when attempting to set or delete the
594 attribute. Previously a TypeError was raised, but this was inconsistent
595 with the equivalent pure-Python implementation.
596
Michael W. Hudson774479c2005-04-18 08:46:17 +0000597- It is now safe to call PyGILState_Release() before
598 PyEval_InitThreads() (note that if there is reason to believe there
599 are multiple threads around you still must call PyEval_InitThreads()
600 before using the Python API; this fix is for extension modules that
601 have no way of knowing if Python is multi-threaded yet).
602
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000603- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
604 disabled caused a crash.
605
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000606- Bug #1165306: instancemethod_new allowed the creation of a method
607 with im_class == im_self == NULL, which caused a crash when called.
608

Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000633 an ferror() call.
634
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000635- min() and max() now support key= arguments with the same meaning as in

655 current thread state when the auto-GIL-state machinery knows about
656 it (since the thread state is being deleted, continuing to remember it
657 can't help, but can hurt if another thread happens to get created with
658 the same thread id).

Georg Brandl828fdef2006-04-01 08:59:03 +0000865 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000866 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000867 module will not be built.
868
Tim Petersc17976e2006-04-01 00:26:53 +0000869- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
870 aren't officially supported here, and trying to use them will probably
871 raise an exception some day. But dicts have been allowed, and "mostly
872 worked", so support for them won't go away without warning.
873
Georg Brandl338ef7d2006-03-31 18:42:16 +0000874- Bug #1445068: getpass.getpass() can now be given an explicit stream

Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000893- email 4.0 package now integrated. This is largely the same as the email 3.0
894 package that was included in Python 2.3, except that PEP 8 module names are
895 now used (e.g. mail.message instead of email.Message). The MIME classes
896 have been moved to a subpackage (e.g. email.mime.text instead of
897 email.MIMEText). The old names are still supported for now. Several
898 deprecated Message methods have been removed and lots of bugs have been
899 fixed. More details can be found in the email package documentation.

902 (a subclass of tuple) that provides incremental decoders and encoders
903 (a way to use stateful codecs without the stream API). Python functions
904 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
905 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
906 have been added.

989
990 "The consensus of researchers in this area (at least as
991 expressed at the NIST Hash Function Workshop 10/31/05),
992 is that SHA-256 is a good choice for the time being, but
993 that research should continue, and other alternatives may
994 arise from this research. The larger SHA's also seem OK."

Martin v. Löwis4afe1542005-03-01 08:09:28 +00001149- Patch #1121234: Properly cleanup _exit and tkerror commands.
1150
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001151- Patch #1049151: xdrlib now unpacks booleans as True or False.
1152
Raymond Hettingerbab41432005-02-05 01:31:19 +00001153- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1154
Guido van Rossumd0641422005-02-03 15:01:24 +00001155- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1156 disables recursive traversal through instance attributes, which can
1157 be exploited in various ways.
1158
Tim Peterse3547fd2005-12-16 23:13:57 +00001159- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001160 flags on the HTTP listening socket.
1161
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001162- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1163 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1164
Tim Peterse3547fd2005-12-16 23:13:57 +00001165- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001166 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1167

1169
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001170- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1171
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001172- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1173
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001174- Enhancements to the csv module:
1175
1176 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001177 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001178 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001179 + Dialect parameter parsing has been re-implemented to improve error
1180 reporting.
1181 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1182 dictates.
1183 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001184 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001185 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001186 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1187 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001188 + reader now allows \r characters to be quoted (previously it only allowed
1189 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001190 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001191 + Dialect classes passed to the module are no longer instantiated by
1192 the module before being parsed (the former validation scheme required
1193 this, but the mechanism was unreliable).
1194 + The dialect registry now contains instances of the internal
1195 C-coded dialect type, rather than references to python objects.
1196 + the internal c-coded dialect type is now immutable.
1197 + register_dialect now accepts the same keyword dialect specifications
1198 as the reader and writer, allowing the user to register dialects
1199 without first creating a dialect class.
1200 + a configurable limit to the size of parsed fields has been added -
1201 previously, an unmatched quote character could result in the entire
1202 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001203 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001204 the parser field size limit (returning the former limit). The initial
1205 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001206 + A line_num attribute has been added to the reader object, which tracks
1207 the number of lines read from the source iterator. This is not
1208 the same as the number of records returned, as records can span
1209 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001210 + reader and writer objects were not being registered with the cyclic-GC.
1211 This has been fixed.
1212
Brett Cannone6539c42005-01-08 02:43:53 +00001213- _DummyThread objects in the threading module now delete self.__block that is
1214 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1215 lock primitives tend to be limited in number and thus should not be wasted on
1216 a _DummyThread object. Fixes bug #1089632.
1217
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001218- The imghdr module now detects Exif files.
1219
Raymond Hettinger6065d322004-12-20 23:51:53 +00001220- StringIO.truncate() now correctly adjusts the size attribute.
1221 (Bug #951915).
1222
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001223- locale.py now uses an updated locale alias table (built using
1224 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1225 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001226 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001227
Raymond Hettinger3557f422004-12-07 12:02:02 +00001228- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1229
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001230- the pickle module no longer accepts the deprecated None option in the
1231 args tuple returned by __reduce__().
1232
Brett Cannon84667c02004-12-07 03:25:18 +00001233- optparse now optionally imports gettext. This allows its use in setup.py.
1234
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001235- the pickle module no longer uses the deprecated bin parameter.
1236
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001237- the shelve module no longer uses the deprecated binary parameter.
1238
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001239- the pstats module no longer uses the deprecated ignore() method.
1240
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001241- the filecmp module no longer uses the deprecated use_statcache argument.
1242
Raymond Hettinger664347b2004-12-04 21:21:53 +00001243- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1244 extended or overridden by subclasses. Formerly, the subclassed method would
1245 be ignored by the rest of the module. (Bug #1078905).
1246
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001247- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001248 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001249
Walter Dörwald36733692004-12-22 12:50:50 +00001250- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1251 once when a size argument is given. This prevents a buffer overflow in the
1252 tokenizer with very long source lines.
1253
Barry Warsaw538561e2006-01-01 21:48:54 +00001254- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1255 immediately after creating the object, without any intervening
1256 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001257
Skip Montanaro05885812005-01-16 20:48:27 +00001258- The reconvert.quote function can now emit triple-quoted strings. The
1259 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001260
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001261- ``UserString.MutableString`` now supports negative indices in
1262 ``__setitem__`` and ``__delitem__``
1263
Greg Ward40407942005-03-05 02:53:17 +00001264- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1265 correctly.
1266
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001267- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1268 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1269 character even if the user has passed a size parameter to get a proper
1270 line ending. Remove the special handling of a "\r\n" that has been split
1271 between two lines.
1272
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001273- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1274 about illegal code points. The codec now supports PEP 293 style error
1275 handlers.
1276
Walter Dörwald78a78b02005-09-01 12:04:29 +00001277- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001278 from the input stream, so that the output is a byte string in the correct
1279 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001280
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001281- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1282 considering it exactly like a '*'.
1283
Walter Dörwald007f8df2005-10-09 19:42:27 +00001284- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1285 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001286
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001287- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1288
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001289- Patch #1413711: Certain patterns of differences were making difflib
1290 touch the recursion limit.
1291
Walter Dörwald58917a62006-03-31 15:26:22 +00001292- Bug #947906: An object oriented interface has been added to the calendar
1293 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001294 called as a script (e.g. via ``python -mcalendar``). Localized month and
1295 weekday names can be ouput (even if an exotic encoding is used) using
1296 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001297
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001298Build
1299-----
1300
Neal Norwitz602d3392006-03-31 08:21:40 +00001301- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1302 by using -mieee gcc option.
1303

1305
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001306- Build support for Win64-AMD64 was added.
1307
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001308- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1309
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001310- Patch #881820: look for openpty and forkpty also in libbsd.
1311
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001312- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1313 The zlib module is now builtin on Windows.
1314
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001315- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1316
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001317- Bug #1189330: configure did not correctly determine the necessary
1318 value of LINKCC if python was built with GCC 4.0.
1319
Trent Mick8321b422005-07-26 02:29:21 +00001320- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1321 vulnerability in zlib 1.2.1 and 1.2.2.
1322
Brett Cannon08cd5982005-04-24 22:26:38 +00001323- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1324 flags that change binary compatibility. Changes were also made to
1325 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001326 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001327
Bob Ippolitoed233462005-03-29 13:47:59 +00001328- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1329 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1330 no longer exists). This configure patch makes things right.
1331
Martin v. Löwise2713be2005-03-08 15:03:08 +00001332- Bug #1158607: Build with --disable-unicode again.
1333
Brett Cannon46d96232005-02-16 00:07:19 +00001334- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1335 defined. Discovered as a result of not being able to build on OS X.
1336
Brett Cannon516592f2004-12-07 00:42:59 +00001337- setup.py now uses the directories specified in LDFLAGS using the -L option
1338 and in CPPFLAGS using the -I option for adding library and include
1339 directories, respectively, for compiling extension modules against. This has
1340 led to the core being compiled using the values in CPPFLAGS. It also removes
1341 the need for the special-casing of both DarwinPorts and Fink for darwin since
1342 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1343 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1344 Fink, ``-I/opt/local/include`` for DarwinPorts).
1345
Brett Cannon43802422005-02-10 20:48:03 +00001346- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1347 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1348 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1349 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001351C API
1352-----
1353
Tim Petersc9d78aa2006-03-26 23:27:58 +00001354- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1355 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1356 is obtained via the ``PyObject_`` family, it must be released via the
1357 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1358 always been officially true, but when Python's small-object allocator was
1359 introduced, an attempt was made to cater to a few extension modules
1360 discovered at the time that obtained memory via ``PyObject_New`` but
1361 released it via ``PyMem_DEL``. It's years later, and if such code still
1362 exists it will fail now (probably with segfaults, but calling wrong
1363 low-level memory management functions can yield many symptoms).
1364
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001365- Added a C API for set and frozenset objects.
1366
Raymond Hettinger66517482004-12-03 11:45:13 +00001367- Removed PyRange_New().
1368
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001369- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1370 mapping argument now. This string is used as a mapping table. Byte values
1371 greater than the length of the string and 0xFFFE are treated as undefined
1372 mappings.
