Neal Norwitz7a5fc282006-05-15 06:48:14 +00007What's New in Python 2.5 alpha 3?
Anthony Baxter51bcb682006-04-05 14:51:42 +00008=================================

Neal Norwitz7a5fc282006-05-15 06:48:14 +000010*Release date: XX-MAY-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
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000065- Patch #1493701: performance enhancements for struct module.
66
Georg Brandl378d5922006-05-17 14:26:50 +000067- Patch #1490224: time.altzone is now set correctly on Cygwin.
68
Georg Brandl8d3342b2006-05-16 07:38:27 +000069- Patch #1435422: zlib's compress and decompress objects now have a
70 copy() method.
71
Neal Norwitz7a5fc282006-05-15 06:48:14 +000072- On Win32, os.listdir now supports arbitrarily-long Unicode path names
73 (up to the system limit of 32K characters).
74
75- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
76 As a result, these functions now raise WindowsError instead of OSError.
77
Tim Peters7a822da2006-05-25 21:50:17 +000078- ``time.clock()`` on Win64 should use the high-performance Windows
79 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
80 Windows platforms).
81
Neal Norwitz7a5fc282006-05-15 06:48:14 +000082- Calling Tk_Init twice is refused if the first call failed as that
83 may deadlock.
84
85Library
86-------
87
Georg Brandl2b330372006-05-28 20:23:12 +000088- Patch #1496206: improve urllib2 handling of passwords with respect to
89 default HTTP and HTTPS ports.
90
George Yoshidaf3c65de2006-05-28 16:39:09 +000091- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
92
Bob Ippolito7298f272006-05-23 18:43:47 +000093- Patch #1281707: speed up gzip.readline.
94
Georg Brandlb89316f2006-05-17 15:51:16 +000095- Patch #1180296: Two new functions were added to the locale module:
96 format_string() to get the effect of "format % items" but locale-aware,
97 and currency() to format a monetary number with currency sign.
98
Georg Brandle3a25832006-05-17 14:56:04 +000099- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
100 and several features added, such as speed and geometry control.
101
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000102- Patch #1488881: add support for external file objects in bz2 compressed
103 tarfiles.
104
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000105- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
106 stdout arguments, making it possible to redirect input and output
107 for remote debugging.
108
109- Patch #1484695: Update the tarfile module to version 0.8. This fixes
110 a couple of issues, notably handling of long file names using the
111 GNU LONGNAME extension.
112
113- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
114 new flag when ``name`` is already the name of an option flag.
115
116- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
117 package.
118
119- Patch #1472854: make the rlcompleter.Completer class usable on non-
120 UNIX platforms.
121
122- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

145What's New in Python 2.5 alpha 2?
146=================================
147
148*Release date: 27-APR-2006*
149
150Core and builtins
151-----------------
152
Thomas Heller1b046642006-04-18 18:51:06 +0000153- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
154 by converting these apis from macros into exported functions again:
155
156 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
157 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
158 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
159 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
160 PyRun_String Py_CompileString
161
Martin v. Löwis45294a92006-04-18 06:24:08 +0000162- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
163
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000164- All uses of PyStructSequence_InitType have been changed to initialize
165 the type objects only once, even if the interpreter is initialized
166 multiple times.
167
Neal Norwitz61546162006-04-14 05:20:28 +0000168- Bug #1454485, array.array('u') could crash the interpreter. This was
169 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
170 to unicode when it didn't make sense. 'u#' now requires a unicode string.
171
172- Py_UNICODE is unsigned. It was always documented as unsigned, but
173 due to a bug had a signed value in previous versions.
174
Tim Peters3a5e8b12006-04-11 01:44:07 +0000175- Patch #837242: ``id()`` of any Python object always gives a positive
176 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
177 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000178 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000179 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000180
Tim Peters3a5e8b12006-04-11 01:44:07 +0000181 def __hash__(self):
182 return id(self) # WRONG
183
184 because a hash result must be a (short) Python int but it was always
185 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000186 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000187 was always usable as a hash value before this patch. That's no longer
188 necessarily so.
189
190- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000191 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000192 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000193 #1454844)
194
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000195- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
196 involving generators that have paused outside of any ``try`` or ``with``
197 blocks. (In 2.5a1, a paused generator that was part of a reference
198 cycle could not be garbage collected, regardless of whether it was
199 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +0000200
Anthony Baxter51bcb682006-04-05 14:51:42 +0000201Extension Modules
202-----------------
203
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000204- Patch #1191065: Fix preprocessor problems on systems where recvfrom
205 is a macro.
206
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000207- Bug #1467952: os.listdir() now correctly raises an error if readdir()
208 fails with an error condition.
209
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000210- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
211
212- Bug #1117761: bsddb.*open() no longer raises an exception when using
213 the cachesize parameter.
214
215- Bug #1149413: bsddb.*open() no longer raises an exception when using
216 a temporary db (file=None) with the 'n' flag to truncate on open.
217
218- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
219 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000220
Armin Rigoa9017c32006-04-19 11:50:27 +0000221- Patch #1062014: AF_UNIX sockets under Linux have a special
222 abstract namespace that is now fully supported.
223
Anthony Baxter51bcb682006-04-05 14:51:42 +0000224Library
225-------
226
Tim Peters711bf302006-04-25 03:31:36 +0000227- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
228 a doctest to be skipped (the code is not run, and the expected output
229 or exception is ignored).
230
Nick Coghlanda2268f2006-04-24 04:37:15 +0000231- Fixed contextlib.nested to cope with exceptions being raised and
232 caught inside exit handlers.
233
Greg Wardab05edc2006-04-23 03:47:58 +0000234- Updated optparse module to Optik 1.5.1 (allow numeric constants in
235 hex, octal, or binary; add ``append_const`` action; keep going if
236 gettext cannot be imported; added ``OptionParser.destroy()`` method;
237 added ``epilog`` for better help generation).
238
Tim Peters21fbd572006-04-21 21:18:10 +0000239- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
240 called from a thread spawned as a side effect of importing a module.
241
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000242- The pydoc module now supports documenting packages contained in
243 .zip or .egg files.
244
245- The pkgutil module now has several new utility functions, such
246 as ``walk_packages()`` to support working with packages that are either
247 in the filesystem or zip files.
248
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000249- The mailbox module can now modify and delete messages from
250 mailboxes, in addition to simply reading them. Thanks to Gregory
251 K. Johnson for writing the code, and to the 2005 Google Summer of
252 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000253
Tim Petersc7605f22006-04-17 21:12:33 +0000254- The ``__del__`` method of class ``local`` in module ``_threading_local``
255 returned before accomplishing any of its intended cleanup.
256

260
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000261- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
262
Anthony Baxtere29002c2006-04-12 12:07:31 +0000263- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
264 Windows. Bug #1469163.
265
Phillip J. Eby47032112006-04-11 01:07:43 +0000266- The warnings, linecache, inspect, traceback, site, and doctest modules
267 were updated to work correctly with modules imported from zipfiles or
268 via other PEP 302 __loader__ objects.
269
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000270- Patch #1467770: Reduce usage of subprocess._active to processes which
271 the application hasn't waited on.

282
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000283- The Makefile now has a reindent target, which runs reindent.py on
284 the library.

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000290- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
291 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000292 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000293 CXX from --with-cxx-main, see description in README.
294

298
Tim Peters8931ff12006-05-13 23:28:20 +0000299- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
300 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

302
Anthony Baxter51bcb682006-04-05 14:51:42 +0000303Tests
304-----
305
Nick Coghlanda2268f2006-04-24 04:37:15 +0000306- test_contextlib now checks contextlib.nested can cope with exceptions
307 being raised and caught inside exit handlers.

Nick Coghlan27ec1a72006-04-24 04:32:47 +0000309- test_cmd_line now checks operation of the -m and -c command switches
310
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000311- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
312 it separately and by hand. It also wasn't cleaning up its changes to
313 the current Decimal context.
314
Thomas Woutersabd08882006-04-26 15:53:30 +0000315- regrtest.py now has a -M option to run tests that test the new limits of
316 containers, on 64-bit architectures. Running these tests is only sensible
317 on 64-bit machines with more than two gigabytes of memory. The argument
318 passed is the maximum amount of memory for the tests to use.

327-------------
328
Tim Petersb06d28c2006-05-12 01:57:59 +0000329- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
330
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000331- PEP 343: Added Context Types section to the library reference
332 and attempted to bring other PEP 343 related documentation into
333 line with the implementation and/or python-dev discussions.
334
Tim Peters8dc73d22006-04-24 02:03:16 +0000335- Bug #1337990: clarified that ``doctest`` does not support examples
336 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000339What's New in Python 2.5 alpha 1?
340=================================
341
Anthony Baxterebed3f62006-04-03 15:03:44 +0000342*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000343
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000344Core and builtins
345-----------------
346
Nick Coghlan43832302006-04-23 17:04:07 +0000347- PEP 338: -m command line switch now delegates to runpy.run_module
348 allowing it to support modules in packages and zipfiles
349
Martin v. Löwisc661b882006-04-20 04:54:23 +0000350- On Windows, .DLL is not an accepted file name extension for
351 extension modules anymore; extensions are only found if they
352 end in .PYD.
353
Martin v. Löwisea62d252006-04-03 10:56:49 +0000354- Bug #1421664: sys.stderr.encoding is now set to the same value as
355 sys.stdout.encoding.
356
Neal Norwitz92e212f2006-04-03 04:48:37 +0000357- __import__ accepts keyword arguments.
358
Georg Brandlccadf842006-03-31 18:54:53 +0000359- Patch #1460496: round() now accepts keyword arguments.
360
Anthony Baxter262c00a2006-03-30 10:53:17 +0000361- Fixed bug #1459029 - unicode reprs were double-escaped.
362
Hye-Shik Changd478f342006-03-23 12:32:36 +0000363- Patch #1396919: The system scope threads are reenabled on FreeBSD
364 5.4 and later versions.
365
Neal Norwitze98ccf62006-03-23 05:39:47 +0000366- Bug #1115379: Compiling a Unicode string with an encoding declaration
367 now gives a SyntaxError.
368
Georg Brandlabd1ff82006-03-18 07:59:59 +0000369- Previously, Python code had no easy way to access the contents of a
370 cell object. Now, a ``cell_contents`` attribute has been added
371 (closes patch #1170323).
372
Tim Peterscf79aac2006-03-16 01:14:46 +0000373- Patch #1123430: Python's small-object allocator now returns an arena to
374 the system ``free()`` when all memory within an arena becomes unused
375 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
376 freed. Some applications will see a drop in virtual memory size now,
377 especially long-running applications that, from time to time, temporarily
378 use a large number of small objects. Note that when Python returns an
379 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000380 platform C library will in turn return that memory to the operating system.
381 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000382 appears to be effective at least on Microsoft C and gcc-based systems.
383 Thanks to Evan Jones for hard work and patience.
384
Georg Brandl533ff6f2006-03-08 18:09:27 +0000385- Patch #1434038: property() now uses the getter's docstring if there is
386 no "doc" argument given. This makes it possible to legitimately use
387 property() as a decorator to produce a read-only property.
388
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000389- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
390 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
391 of requiring an int or long in slicing and a few other contexts, enabling
392 other objects (e.g. Numeric Python's integers) to be used as slice indices.
393
Neal Norwitz995acdf2006-03-07 05:01:00 +0000394- Fixed various bugs reported by Coverity's Prevent tool.
395
Brett Cannonbf364092006-03-01 04:25:17 +0000396- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
397 new exception base class, BaseException, which has a new message attribute.
398 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
399 Raising a string exception now raises a DeprecationWarning.
400
Thomas Woutersfb609f42006-02-28 16:37:25 +0000401- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
402 explicitly relative, using 'from .module import name' to mean 'from the same
403 package as this module is in. Imports without dots still default to the
404 old relative-then-absolute, unless 'from __future__ import
405 absolute_import' is used.
406
Brett Cannona7446e32006-02-27 23:39:10 +0000407- Properly check if 'warnings' raises an exception (usually when a filter set
408 to "error" is triggered) when raising a warning for raising string
409 exceptions.
410
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000411- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000412 The name was removed from Include/code.h.
413
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000414- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000415
Guido van Rossum1968ad32006-02-25 22:38:04 +0000416- Patch 1433928:
417 - The copy module now "copies" function objects (as atomic objects).
418 - dict.__getitem__ now looks for a __missing__ hook before raising
419 KeyError.
420
Tim Peters84ef21c2006-02-28 20:39:06 +0000421- PEP 343: with statement implemented. Needs ``from __future__ import
422 with_statement``. Use of 'with' as a variable will generate a warning.
423 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000424 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000425 The following objects have __context__ methods:
426 - The built-in file type.
427 - The thread.LockType type.
428 - The following types defined by the threading module:
429 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
430 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000431
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000432- Fix the encodings package codec search function to only search
433 inside its own package. Fixes problem reported in patch #1433198.
434
435 Note: Codec packages should implement and register their own
436 codec search function. PEP 100 has the details.
437
Martin v. Löwis18e16552006-02-15 17:27:45 +0000438- PEP 353: Using ssize_t as the index type.
439
Neal Norwitzfc76d632006-01-10 06:03:13 +0000440- Patch #1400181, fix unicode string formatting to not use the locale.
441 This is how string objects work. u'%f' could use , instead of .
442 for the decimal point. Now both strings and unicode always use periods.
443
Neal Norwitz671b9e32006-01-09 07:07:12 +0000444- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
445 configure would break checking curses.h.
446
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000447- Bug #959576: The pwd module is now builtin. This allows Python to be
448 built on UNIX platforms without $HOME set.
449
Neal Norwitzc10978f2005-12-19 06:07:16 +0000450- Bug #1072182, fix some potential problems if characters are signed.
451
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000452- Bug #889500, fix line number on SyntaxWarning for global declarations.
453
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000454- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
455
Neal Norwitze7214a12005-12-18 05:03:17 +0000456- Support for converting hex strings to floats no longer works.
457 This was not portable. float('0x3') now raises a ValueError.
458
Barry Warsaw2a38a862005-12-18 01:27:35 +0000459- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000460 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000461 is now displayed in interactive prompt banner.
462
Georg Brandlfa166682005-12-17 21:45:17 +0000463- Implementation of PEP 341 - Unification of try/except and try/finally.
464 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000465 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000466
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000467- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
468 now encodes backslash correctly.
469
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000470- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
471
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000472- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000473 and long longs.
474
Neal Norwitz67715f02005-11-09 06:59:35 +0000475- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000476 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000477 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000478
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000479- Replaced most Unicode charmap codecs with new ones using the
480 new Unicode translate string feature in the builtin charmap
481 codec; the codecs were created from the mapping tables available
482 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
483 encodings now include a mapping for the Apple logo)
484
Tim Peterse3547fd2005-12-16 23:13:57 +0000485- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000486
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000487- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000488
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000489- A new AST parser implementation was completed. The abstract
490 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000491 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000492
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000493- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000494 The following code now raises a SyntaxError: foo(a = i for i in range(10))
495
Neal Norwitz708e51a2005-10-03 04:48:15 +0000496- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
497
Neal Norwitz11bd1192005-10-03 00:54:56 +0000498- SF Bug #887946: fix segfault when redirecting stdin from a directory.
499 Provide a warning when a directory is passed on the command line.
500
Neal Norwitz40d37812005-10-02 01:48:49 +0000501- Fix segfault with invalid coding.
502
503- SF bug #772896: unknown encoding results in MemoryError.
504
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000505- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000506 supported a __len__() method which evaluated to False when the iterator
507 was empty.
508
Guido van Rossum630db602005-09-20 18:49:54 +0000509- On 64-bit platforms, when __len__() returns a value that cannot be
510 represented as a C int, raise OverflowError.
511
Skip Montanarof8948ca2005-09-19 03:54:46 +0000512- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000513 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000514
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000515- SF bug #893549: parsing keyword arguments was broken with a few format
516 codes.
517
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000518- Changes donated by Elemental Security to make it work on AIX 5.3
519 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
520 bug #105470: test_pwd fails on 64bit system (Opteron).
521
Guido van Rossum539c6622005-09-14 17:49:54 +0000522- Changes donated by Elemental Security to make it work on HP-UX 11 on
523 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
524
Georg Brandl4550b8d2005-08-26 06:43:52 +0000525- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000526 (fixes bug #1119418).
527
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000528- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
529
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000530- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
531 exceptions that cause a function to exit.
532
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000533- The implementation of set() and frozenset() was revised to use its
534 own internal data structure. Memory consumption is reduced by 1/3
535 and there are modest speed-ups as well. The API is unchanged.
536
Tim Petersde7990b2005-07-17 23:45:23 +0000537- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
538
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000539- SF bug #1229429: PyObject_CallMethod failed to decrement some
540 reference counts in some error exit cases.
541
Tim Petersecc6e6a2005-07-10 22:30:55 +0000542- SF bug #1185883: Python's small-object memory allocator took over
543 a block managed by the platform C library whenever a realloc specified
544 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000545 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000546 portable way to copy data from the C-managed block into Python's
547 small-object space without risking a memory fault. Python's small-object
548 realloc now leaves such blocks under the control of the platform C
549 realloc.
550
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000551- SF bug #1232517: An overflow error was not detected properly when
552 attempting to convert a large float to an int in os.utime().
553
Raymond Hettinger3296e692005-06-29 23:29:56 +0000554- SF bug #1224347: hex longs now print with lowercase letters just
555 like their int counterparts.
556
Michael W. Hudson188d4362005-06-20 16:52:57 +0000557- SF bug #1163563: the original fix for bug #1010677 ("thread Module
558 Breaks PyGILState_Ensure()") broke badly in the case of multiple
559 interpreter states; back out that fix and do a better job (see
560 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
561 for a longer write-up of the problem).
562
Michael W. Hudsondf888462005-06-03 14:41:55 +0000563- SF patch #1180995: marshal now uses a binary format by default when
564 serializing floats.
565
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000566- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
567 the routines that promise to produce IEEE 754 binary representations
568 of floats now simply copy bytes around.
569
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000570- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
571 278.
572
Brett Cannonc3647ac2005-04-26 03:45:26 +0000573- patch #1109424: int, long, float, complex, and unicode now check for the
574 proper magic slot for type conversions when subclassed. Previously the
575 magic slot was ignored during conversion. Semantics now match the way
576 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000577 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000578 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000579 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000580
Barry Warsawc8d907c2005-04-19 23:43:40 +0000581- Descriptors defined in C with a PyGetSetDef structure, where the setter is
582 NULL, now raise an AttributeError when attempting to set or delete the
583 attribute. Previously a TypeError was raised, but this was inconsistent
584 with the equivalent pure-Python implementation.
585
Michael W. Hudson774479c2005-04-18 08:46:17 +0000586- It is now safe to call PyGILState_Release() before
587 PyEval_InitThreads() (note that if there is reason to believe there
588 are multiple threads around you still must call PyEval_InitThreads()
589 before using the Python API; this fix is for extension modules that
590 have no way of knowing if Python is multi-threaded yet).
591
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000592- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
593 disabled caused a crash.
594
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000595- Bug #1165306: instancemethod_new allowed the creation of a method
596 with im_class == im_self == NULL, which caused a crash when called.
597
Tim Petersecc6e6a2005-07-10 22:30:55 +0000598- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000599 fixes the crash seen in bug #1165761
600
Raymond Hettinger96229b12005-03-11 06:49:40 +0000601- Added two new builtins, any() and all().
602
Brett Cannon409d8f22005-03-05 06:47:57 +0000603- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000604 (e.g., ``class C(): pass`` is no longer a syntax error).
605 Patch #1176012 added support to the 'parser' module and 'compiler' package
606 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000607

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

837-------
838
Nick Coghlan43832302006-04-23 17:04:07 +0000839- PEP 338: new module runpy defines a run_module function to support
840 executing modules which provide access to source code or a code object
841 via the PEP 302 import mechanisms.

Georg Brandl828fdef2006-04-01 08:59:03 +0000854 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000855 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000856 module will not be built.
857
Tim Petersc17976e2006-04-01 00:26:53 +0000858- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
859 aren't officially supported here, and trying to use them will probably
860 raise an exception some day. But dicts have been allowed, and "mostly
861 worked", so support for them won't go away without warning.
862
Georg Brandl338ef7d2006-03-31 18:42:16 +0000863- Bug #1445068: getpass.getpass() can now be given an explicit stream

865
Georg Brandl22ec80b2006-03-31 18:25:44 +0000866- Patch #1462313, bug #1443328: the pickle modules now can handle classes

Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000882- email 4.0 package now integrated. This is largely the same as the email 3.0
883 package that was included in Python 2.3, except that PEP 8 module names are
884 now used (e.g. mail.message instead of email.Message). The MIME classes
885 have been moved to a subpackage (e.g. email.mime.text instead of
886 email.MIMEText). The old names are still supported for now. Several
887 deprecated Message methods have been removed and lots of bugs have been
888 fixed. More details can be found in the email package documentation.

Walter Dörwald40108c92006-03-27 08:15:44 +0000890- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
891 (a subclass of tuple) that provides incremental decoders and encoders
892 (a way to use stateful codecs without the stream API). Python functions
893 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
894 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
895 have been added.

976 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
977 Ronald L. Rivest offered this advice for Python:
978
979 "The consensus of researchers in this area (at least as
980 expressed at the NIST Hash Function Workshop 10/31/05),
981 is that SHA-256 is a good choice for the time being, but
982 that research should continue, and other alternatives may
983 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000984

Tim Peterse3547fd2005-12-16 23:13:57 +00001148- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001149 flags on the HTTP listening socket.
1150
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001151- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1152 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1153
Tim Peterse3547fd2005-12-16 23:13:57 +00001154- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001155 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1156
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001157- Bug #1110478: Revert os.environ.update to do putenv again.
1158
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001159- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1160
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001161- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1162
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001163- Enhancements to the csv module:
1164
1165 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001166 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001167 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001168 + Dialect parameter parsing has been re-implemented to improve error
1169 reporting.
1170 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1171 dictates.
1172 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001173 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001174 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001175 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1176 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001177 + reader now allows \r characters to be quoted (previously it only allowed
1178 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001179 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001180 + Dialect classes passed to the module are no longer instantiated by
1181 the module before being parsed (the former validation scheme required
1182 this, but the mechanism was unreliable).
1183 + The dialect registry now contains instances of the internal
1184 C-coded dialect type, rather than references to python objects.
1185 + the internal c-coded dialect type is now immutable.
1186 + register_dialect now accepts the same keyword dialect specifications
1187 as the reader and writer, allowing the user to register dialects
1188 without first creating a dialect class.
1189 + a configurable limit to the size of parsed fields has been added -
1190 previously, an unmatched quote character could result in the entire
1191 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001192 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001193 the parser field size limit (returning the former limit). The initial
1194 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001195 + A line_num attribute has been added to the reader object, which tracks
1196 the number of lines read from the source iterator. This is not
1197 the same as the number of records returned, as records can span
1198 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001199 + reader and writer objects were not being registered with the cyclic-GC.
1200 This has been fixed.
1201
Brett Cannone6539c42005-01-08 02:43:53 +00001202- _DummyThread objects in the threading module now delete self.__block that is
1203 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1204 lock primitives tend to be limited in number and thus should not be wasted on
1205 a _DummyThread object. Fixes bug #1089632.
1206
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001207- The imghdr module now detects Exif files.
1208
Raymond Hettinger6065d322004-12-20 23:51:53 +00001209- StringIO.truncate() now correctly adjusts the size attribute.
1210 (Bug #951915).
1211
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001212- locale.py now uses an updated locale alias table (built using
1213 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1214 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001215 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001216
Raymond Hettinger3557f422004-12-07 12:02:02 +00001217- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1218
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001219- the pickle module no longer accepts the deprecated None option in the
1220 args tuple returned by __reduce__().
1221
Brett Cannon84667c02004-12-07 03:25:18 +00001222- optparse now optionally imports gettext. This allows its use in setup.py.
1223
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001224- the pickle module no longer uses the deprecated bin parameter.
1225
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001226- the shelve module no longer uses the deprecated binary parameter.
1227
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001228- the pstats module no longer uses the deprecated ignore() method.
1229
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001230- the filecmp module no longer uses the deprecated use_statcache argument.
1231
Raymond Hettinger664347b2004-12-04 21:21:53 +00001232- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1233 extended or overridden by subclasses. Formerly, the subclassed method would
1234 be ignored by the rest of the module. (Bug #1078905).
1235
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001236- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001237 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001238
Walter Dörwald36733692004-12-22 12:50:50 +00001239- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1240 once when a size argument is given. This prevents a buffer overflow in the
1241 tokenizer with very long source lines.
1242
Barry Warsaw538561e2006-01-01 21:48:54 +00001243- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1244 immediately after creating the object, without any intervening
1245 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001246
Skip Montanaro05885812005-01-16 20:48:27 +00001247- The reconvert.quote function can now emit triple-quoted strings. The
1248 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001249
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001250- ``UserString.MutableString`` now supports negative indices in
1251 ``__setitem__`` and ``__delitem__``
1252
Greg Ward40407942005-03-05 02:53:17 +00001253- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1254 correctly.
1255
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001256- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1257 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1258 character even if the user has passed a size parameter to get a proper
1259 line ending. Remove the special handling of a "\r\n" that has been split
1260 between two lines.
1261
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001262- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1263 about illegal code points. The codec now supports PEP 293 style error
1264 handlers.
1265
Walter Dörwald78a78b02005-09-01 12:04:29 +00001266- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001267 from the input stream, so that the output is a byte string in the correct
1268 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001269
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001270- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1271 considering it exactly like a '*'.
1272
Walter Dörwald007f8df2005-10-09 19:42:27 +00001273- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1274 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001275
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001276- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1277
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001278- Patch #1413711: Certain patterns of differences were making difflib
1279 touch the recursion limit.
1280
Walter Dörwald58917a62006-03-31 15:26:22 +00001281- Bug #947906: An object oriented interface has been added to the calendar
1282 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001283 called as a script (e.g. via ``python -mcalendar``). Localized month and
1284 weekday names can be ouput (even if an exotic encoding is used) using
1285 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001286
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001287Build
1288-----
1289
Neal Norwitz602d3392006-03-31 08:21:40 +00001290- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1291 by using -mieee gcc option.
1292

1294
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001295- Build support for Win64-AMD64 was added.
1296
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001297- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1298
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001299- Patch #881820: look for openpty and forkpty also in libbsd.
1300
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001301- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1302 The zlib module is now builtin on Windows.
1303
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001304- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1305
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001306- Bug #1189330: configure did not correctly determine the necessary
1307 value of LINKCC if python was built with GCC 4.0.
1308
Trent Mick8321b422005-07-26 02:29:21 +00001309- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1310 vulnerability in zlib 1.2.1 and 1.2.2.
1311
Brett Cannon08cd5982005-04-24 22:26:38 +00001312- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1313 flags that change binary compatibility. Changes were also made to
1314 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001315 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001316
Bob Ippolitoed233462005-03-29 13:47:59 +00001317- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1318 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1319 no longer exists). This configure patch makes things right.
1320
Martin v. Löwise2713be2005-03-08 15:03:08 +00001321- Bug #1158607: Build with --disable-unicode again.
1322
Brett Cannon46d96232005-02-16 00:07:19 +00001323- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1324 defined. Discovered as a result of not being able to build on OS X.
1325
Brett Cannon516592f2004-12-07 00:42:59 +00001326- setup.py now uses the directories specified in LDFLAGS using the -L option
1327 and in CPPFLAGS using the -I option for adding library and include
1328 directories, respectively, for compiling extension modules against. This has
1329 led to the core being compiled using the values in CPPFLAGS. It also removes
1330 the need for the special-casing of both DarwinPorts and Fink for darwin since
1331 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1332 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1333 Fink, ``-I/opt/local/include`` for DarwinPorts).
1334
Brett Cannon43802422005-02-10 20:48:03 +00001335- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1336 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1337 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1338 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001340C API
1341-----
1342
Tim Petersc9d78aa2006-03-26 23:27:58 +00001343- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1344 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1345 is obtained via the ``PyObject_`` family, it must be released via the
1346 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1347 always been officially true, but when Python's small-object allocator was
1348 introduced, an attempt was made to cater to a few extension modules
1349 discovered at the time that obtained memory via ``PyObject_New`` but
1350 released it via ``PyMem_DEL``. It's years later, and if such code still
1351 exists it will fail now (probably with segfaults, but calling wrong
1352 low-level memory management functions can yield many symptoms).
1353
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001354- Added a C API for set and frozenset objects.
1355
Raymond Hettinger66517482004-12-03 11:45:13 +00001356- Removed PyRange_New().
1357
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001358- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1359 mapping argument now. This string is used as a mapping table. Byte values
1360 greater than the length of the string and 0xFFFE are treated as undefined
1361 mappings.

1421 vimrc to it (was previous up a level).
1422
Georg Brandl56897312005-08-24 18:32:30 +00001423- Added two new files to Tools/scripts: pysource.py, which recursively
