Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Martin v. Löwisd004fc82006-05-27 08:36:52 +000015- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
16 Unicode 4.1.
17
Georg Brandlf4ef1162006-05-26 18:03:31 +000018- Patch #921466: sys.path_importer_cache is now used to cache valid and
19 invalid file paths for the built-in import machinery which leads to
20 fewer open calls on startup.
21
Tim Peters696cf432006-05-24 21:10:40 +000022- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
23 of-2 bases. The largest speedup is for inputs with about 1000 decimal
24 digits. Conversion from non-power-of-2 bases remains quadratic-time in
25 the number of input digits (it was and remains linear-time for bases
26 2, 4, 8, 16 and 32).
27
Tim Petersb713ec22006-05-23 18:45:30 +000028- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
29 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
30 an integer close to ``sys.maxint``. This was repaired by patch
31 #1335972, which also gives a nice speedup.
32
Richard Jonescebbefc2006-05-23 18:28:17 +000033- Patch #1337051: reduced size of frame objects.
34
35- PyErr_NewException now accepts a tuple of base classes as its
36 "base" parameter.
37
Richard Jones7c88dcc2006-05-23 10:37:38 +000038- Patch #876206: function call speedup by retaining allocated frame
39 objects.
40
Georg Brandl7b90e162006-05-18 07:01:27 +000041- Bug #1462152: file() now checks more thoroughly for invalid mode
42 strings and removes a possible "U" before passing the mode to the
43 C library function.
44
Neal Norwitz1004a532006-05-15 07:17:23 +000045- Patch #1488312, Fix memory alignment problem on SPARC in unicode
46
Neal Norwitz373f0a72006-05-15 07:04:36 +000047- Bug #1487966: Fix SystemError with conditional expression in assignment
48
Martin v. Löwis879768d2006-05-11 13:28:43 +000049- WindowsError now has two error code attributes: errno, which carries
50 the error values from errno.h, and winerror, which carries the error
51 values from winerror.h. Previous versions put the winerror.h values
52 (from GetLastError()) into the errno attribute.
53
Martin v. Löwis77736712006-05-04 05:51:03 +000054- Patch #1475845: Raise IndentationError for unexpected indent.
55
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000056- Patch #1479181: split open() and file() from being aliases for each other.
57
Neal Norwitz7a5fc282006-05-15 06:48:14 +000058Extension Modules
59-----------------
60
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000061- Patch #1493701: performance enhancements for struct module.
62
Georg Brandl378d5922006-05-17 14:26:50 +000063- Patch #1490224: time.altzone is now set correctly on Cygwin.
64
Georg Brandl8d3342b2006-05-16 07:38:27 +000065- Patch #1435422: zlib's compress and decompress objects now have a
66 copy() method.
67
Neal Norwitz7a5fc282006-05-15 06:48:14 +000068- On Win32, os.listdir now supports arbitrarily-long Unicode path names
69 (up to the system limit of 32K characters).
70
71- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
72 As a result, these functions now raise WindowsError instead of OSError.
73
Tim Peters7a822da2006-05-25 21:50:17 +000074- ``time.clock()`` on Win64 should use the high-performance Windows
75 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
76 Windows platforms).
77
Neal Norwitz7a5fc282006-05-15 06:48:14 +000078- Calling Tk_Init twice is refused if the first call failed as that
79 may deadlock.
80
81Library
82-------
83
Bob Ippolito7298f272006-05-23 18:43:47 +000084- Patch #1281707: speed up gzip.readline.
85
Georg Brandlb89316f2006-05-17 15:51:16 +000086- Patch #1180296: Two new functions were added to the locale module:
87 format_string() to get the effect of "format % items" but locale-aware,
88 and currency() to format a monetary number with currency sign.
89
Georg Brandle3a25832006-05-17 14:56:04 +000090- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
91 and several features added, such as speed and geometry control.
92
Georg Brandl49c8f4c2006-05-15 19:30:35 +000093- Patch #1488881: add support for external file objects in bz2 compressed
94 tarfiles.
95
Neal Norwitz7a5fc282006-05-15 06:48:14 +000096- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
97 stdout arguments, making it possible to redirect input and output
98 for remote debugging.
99
100- Patch #1484695: Update the tarfile module to version 0.8. This fixes
101 a couple of issues, notably handling of long file names using the
102 GNU LONGNAME extension.
103
104- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
105 new flag when ``name`` is already the name of an option flag.
106
107- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
108 package.
109
110- Patch #1472854: make the rlcompleter.Completer class usable on non-
111 UNIX platforms.
112
113- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Martin v. Löwisa43190b2006-05-22 09:15:18 +0000118- Patch #1492356: Port to Windows CE.
119
Neal Norwitz58e28882006-05-19 07:00:58 +0000120- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.

136What's New in Python 2.5 alpha 2?
137=================================
138
139*Release date: 27-APR-2006*
140
141Core and builtins
142-----------------
143
Thomas Heller1b046642006-04-18 18:51:06 +0000144- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
145 by converting these apis from macros into exported functions again:
146
147 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
148 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
149 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
150 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
151 PyRun_String Py_CompileString
152
Martin v. Löwis45294a92006-04-18 06:24:08 +0000153- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
154
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000155- All uses of PyStructSequence_InitType have been changed to initialize
156 the type objects only once, even if the interpreter is initialized
157 multiple times.
158
Neal Norwitz61546162006-04-14 05:20:28 +0000159- Bug #1454485, array.array('u') could crash the interpreter. This was
160 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
161 to unicode when it didn't make sense. 'u#' now requires a unicode string.
162
163- Py_UNICODE is unsigned. It was always documented as unsigned, but
164 due to a bug had a signed value in previous versions.
165
Tim Peters3a5e8b12006-04-11 01:44:07 +0000166- Patch #837242: ``id()`` of any Python object always gives a positive
167 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
168 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000169 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000170 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000171
Tim Peters3a5e8b12006-04-11 01:44:07 +0000172 def __hash__(self):
173 return id(self) # WRONG
174
175 because a hash result must be a (short) Python int but it was always
176 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000177 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000178 was always usable as a hash value before this patch. That's no longer
179 necessarily so.
180
181- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000182 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000183 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000184 #1454844)
185
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000186- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
187 involving generators that have paused outside of any ``try`` or ``with``
188 blocks. (In 2.5a1, a paused generator that was part of a reference
189 cycle could not be garbage collected, regardless of whether it was
190 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000192Extension Modules
193-----------------
194
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000195- Patch #1191065: Fix preprocessor problems on systems where recvfrom
196 is a macro.
197
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000198- Bug #1467952: os.listdir() now correctly raises an error if readdir()
199 fails with an error condition.
200
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000201- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
202
203- Bug #1117761: bsddb.*open() no longer raises an exception when using
204 the cachesize parameter.
205
206- Bug #1149413: bsddb.*open() no longer raises an exception when using
207 a temporary db (file=None) with the 'n' flag to truncate on open.
208
209- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
210 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000211
Armin Rigoa9017c32006-04-19 11:50:27 +0000212- Patch #1062014: AF_UNIX sockets under Linux have a special
213 abstract namespace that is now fully supported.
214
Anthony Baxter51bcb682006-04-05 14:51:42 +0000215Library
216-------
217
Tim Peters711bf302006-04-25 03:31:36 +0000218- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
219 a doctest to be skipped (the code is not run, and the expected output
220 or exception is ignored).
221
Nick Coghlanda2268f2006-04-24 04:37:15 +0000222- Fixed contextlib.nested to cope with exceptions being raised and
223 caught inside exit handlers.
224
Greg Wardab05edc2006-04-23 03:47:58 +0000225- Updated optparse module to Optik 1.5.1 (allow numeric constants in
226 hex, octal, or binary; add ``append_const`` action; keep going if
227 gettext cannot be imported; added ``OptionParser.destroy()`` method;
228 added ``epilog`` for better help generation).
229
Tim Peters21fbd572006-04-21 21:18:10 +0000230- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
231 called from a thread spawned as a side effect of importing a module.
232
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000233- The pydoc module now supports documenting packages contained in
234 .zip or .egg files.
235
236- The pkgutil module now has several new utility functions, such
237 as ``walk_packages()`` to support working with packages that are either
238 in the filesystem or zip files.
239
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000240- The mailbox module can now modify and delete messages from
241 mailboxes, in addition to simply reading them. Thanks to Gregory
242 K. Johnson for writing the code, and to the 2005 Google Summer of
243 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000244
Tim Petersc7605f22006-04-17 21:12:33 +0000245- The ``__del__`` method of class ``local`` in module ``_threading_local``
246 returned before accomplishing any of its intended cleanup.
247

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000252- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
253
Anthony Baxtere29002c2006-04-12 12:07:31 +0000254- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
255 Windows. Bug #1469163.
256
Phillip J. Eby47032112006-04-11 01:07:43 +0000257- The warnings, linecache, inspect, traceback, site, and doctest modules
258 were updated to work correctly with modules imported from zipfiles or
259 via other PEP 302 __loader__ objects.
260
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000261- Patch #1467770: Reduce usage of subprocess._active to processes which
262 the application hasn't waited on.
263

Martin v. Löwis4be4e652006-04-17 19:25:49 +0000274- The Makefile now has a reindent target, which runs reindent.py on
275 the library.
276

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000281- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
282 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000283 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000284 CXX from --with-cxx-main, see description in README.
285

Tim Peters8931ff12006-05-13 23:28:20 +0000290- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
291 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

296
Nick Coghlanda2268f2006-04-24 04:37:15 +0000297- test_contextlib now checks contextlib.nested can cope with exceptions
298 being raised and caught inside exit handlers.

Nick Coghlan27ec1a72006-04-24 04:32:47 +0000300- test_cmd_line now checks operation of the -m and -c command switches
301
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000302- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
303 it separately and by hand. It also wasn't cleaning up its changes to
304 the current Decimal context.
305
Thomas Woutersabd08882006-04-26 15:53:30 +0000306- regrtest.py now has a -M option to run tests that test the new limits of
307 containers, on 64-bit architectures. Running these tests is only sensible
308 on 64-bit machines with more than two gigabytes of memory. The argument
309 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000335Core and builtins
336-----------------
337
Nick Coghlan43832302006-04-23 17:04:07 +0000338- PEP 338: -m command line switch now delegates to runpy.run_module
339 allowing it to support modules in packages and zipfiles
340
Martin v. Löwisc661b882006-04-20 04:54:23 +0000341- On Windows, .DLL is not an accepted file name extension for
342 extension modules anymore; extensions are only found if they
343 end in .PYD.
344
Martin v. Löwisea62d252006-04-03 10:56:49 +0000345- Bug #1421664: sys.stderr.encoding is now set to the same value as
346 sys.stdout.encoding.
347
Neal Norwitz92e212f2006-04-03 04:48:37 +0000348- __import__ accepts keyword arguments.
349
Georg Brandlccadf842006-03-31 18:54:53 +0000350- Patch #1460496: round() now accepts keyword arguments.
351
Anthony Baxter262c00a2006-03-30 10:53:17 +0000352- Fixed bug #1459029 - unicode reprs were double-escaped.
353
Hye-Shik Changd478f342006-03-23 12:32:36 +0000354- Patch #1396919: The system scope threads are reenabled on FreeBSD
355 5.4 and later versions.
356
Neal Norwitze98ccf62006-03-23 05:39:47 +0000357- Bug #1115379: Compiling a Unicode string with an encoding declaration
358 now gives a SyntaxError.
359
Georg Brandlabd1ff82006-03-18 07:59:59 +0000360- Previously, Python code had no easy way to access the contents of a
361 cell object. Now, a ``cell_contents`` attribute has been added
362 (closes patch #1170323).
363
Tim Peterscf79aac2006-03-16 01:14:46 +0000364- Patch #1123430: Python's small-object allocator now returns an arena to
365 the system ``free()`` when all memory within an arena becomes unused
366 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
367 freed. Some applications will see a drop in virtual memory size now,
368 especially long-running applications that, from time to time, temporarily
369 use a large number of small objects. Note that when Python returns an
370 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000371 platform C library will in turn return that memory to the operating system.
372 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000373 appears to be effective at least on Microsoft C and gcc-based systems.
374 Thanks to Evan Jones for hard work and patience.
375
Georg Brandl533ff6f2006-03-08 18:09:27 +0000376- Patch #1434038: property() now uses the getter's docstring if there is
377 no "doc" argument given. This makes it possible to legitimately use
378 property() as a decorator to produce a read-only property.
379
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000380- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
381 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
382 of requiring an int or long in slicing and a few other contexts, enabling
383 other objects (e.g. Numeric Python's integers) to be used as slice indices.
384
Neal Norwitz995acdf2006-03-07 05:01:00 +0000385- Fixed various bugs reported by Coverity's Prevent tool.
386
Brett Cannonbf364092006-03-01 04:25:17 +0000387- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
388 new exception base class, BaseException, which has a new message attribute.
389 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
390 Raising a string exception now raises a DeprecationWarning.
391
Thomas Woutersfb609f42006-02-28 16:37:25 +0000392- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
393 explicitly relative, using 'from .module import name' to mean 'from the same
394 package as this module is in. Imports without dots still default to the
395 old relative-then-absolute, unless 'from __future__ import
396 absolute_import' is used.
397
Brett Cannona7446e32006-02-27 23:39:10 +0000398- Properly check if 'warnings' raises an exception (usually when a filter set
399 to "error" is triggered) when raising a warning for raising string
400 exceptions.
401
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000402- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000403 The name was removed from Include/code.h.
404
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000405- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000406
Guido van Rossum1968ad32006-02-25 22:38:04 +0000407- Patch 1433928:
408 - The copy module now "copies" function objects (as atomic objects).
409 - dict.__getitem__ now looks for a __missing__ hook before raising
410 KeyError.
411
Tim Peters84ef21c2006-02-28 20:39:06 +0000412- PEP 343: with statement implemented. Needs ``from __future__ import
413 with_statement``. Use of 'with' as a variable will generate a warning.
414 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000415 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000416 The following objects have __context__ methods:
417 - The built-in file type.
418 - The thread.LockType type.
419 - The following types defined by the threading module:
420 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
421 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000422
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000423- Fix the encodings package codec search function to only search
424 inside its own package. Fixes problem reported in patch #1433198.
425
426 Note: Codec packages should implement and register their own
427 codec search function. PEP 100 has the details.
428
Martin v. Löwis18e16552006-02-15 17:27:45 +0000429- PEP 353: Using ssize_t as the index type.
430
Neal Norwitzfc76d632006-01-10 06:03:13 +0000431- Patch #1400181, fix unicode string formatting to not use the locale.
432 This is how string objects work. u'%f' could use , instead of .
433 for the decimal point. Now both strings and unicode always use periods.
434
Neal Norwitz671b9e32006-01-09 07:07:12 +0000435- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
436 configure would break checking curses.h.
437
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000438- Bug #959576: The pwd module is now builtin. This allows Python to be
439 built on UNIX platforms without $HOME set.
440
Neal Norwitzc10978f2005-12-19 06:07:16 +0000441- Bug #1072182, fix some potential problems if characters are signed.
442
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000443- Bug #889500, fix line number on SyntaxWarning for global declarations.
444
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000445- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
446
Neal Norwitze7214a12005-12-18 05:03:17 +0000447- Support for converting hex strings to floats no longer works.
448 This was not portable. float('0x3') now raises a ValueError.
449
Barry Warsaw2a38a862005-12-18 01:27:35 +0000450- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000451 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000452 is now displayed in interactive prompt banner.
453
Georg Brandlfa166682005-12-17 21:45:17 +0000454- Implementation of PEP 341 - Unification of try/except and try/finally.
455 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000456 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000457
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000458- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
459 now encodes backslash correctly.
460
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000461- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
462
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000463- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000464 and long longs.
465
Neal Norwitz67715f02005-11-09 06:59:35 +0000466- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000467 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000468 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000469
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000470- Replaced most Unicode charmap codecs with new ones using the
471 new Unicode translate string feature in the builtin charmap
472 codec; the codecs were created from the mapping tables available
473 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
474 encodings now include a mapping for the Apple logo)
475
Tim Peterse3547fd2005-12-16 23:13:57 +0000476- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000477
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000478- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000479
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000480- A new AST parser implementation was completed. The abstract
481 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000482 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000483
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000484- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000485 The following code now raises a SyntaxError: foo(a = i for i in range(10))
486
Neal Norwitz708e51a2005-10-03 04:48:15 +0000487- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
488
Neal Norwitz11bd1192005-10-03 00:54:56 +0000489- SF Bug #887946: fix segfault when redirecting stdin from a directory.
490 Provide a warning when a directory is passed on the command line.
491
Neal Norwitz40d37812005-10-02 01:48:49 +0000492- Fix segfault with invalid coding.
493
494- SF bug #772896: unknown encoding results in MemoryError.
495
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000496- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000497 supported a __len__() method which evaluated to False when the iterator
498 was empty.
499
Guido van Rossum630db602005-09-20 18:49:54 +0000500- On 64-bit platforms, when __len__() returns a value that cannot be
501 represented as a C int, raise OverflowError.
502
Skip Montanarof8948ca2005-09-19 03:54:46 +0000503- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000504 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000505
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000506- SF bug #893549: parsing keyword arguments was broken with a few format
507 codes.
508
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000509- Changes donated by Elemental Security to make it work on AIX 5.3
510 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
511 bug #105470: test_pwd fails on 64bit system (Opteron).
512
Guido van Rossum539c6622005-09-14 17:49:54 +0000513- Changes donated by Elemental Security to make it work on HP-UX 11 on
514 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
515
Georg Brandl4550b8d2005-08-26 06:43:52 +0000516- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000517 (fixes bug #1119418).
518
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000519- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
520
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000521- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
522 exceptions that cause a function to exit.
523
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000524- The implementation of set() and frozenset() was revised to use its
525 own internal data structure. Memory consumption is reduced by 1/3
526 and there are modest speed-ups as well. The API is unchanged.
527
Tim Petersde7990b2005-07-17 23:45:23 +0000528- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
529
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000530- SF bug #1229429: PyObject_CallMethod failed to decrement some
531 reference counts in some error exit cases.
532
Tim Petersecc6e6a2005-07-10 22:30:55 +0000533- SF bug #1185883: Python's small-object memory allocator took over
534 a block managed by the platform C library whenever a realloc specified
535 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000536 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000537 portable way to copy data from the C-managed block into Python's
538 small-object space without risking a memory fault. Python's small-object
539 realloc now leaves such blocks under the control of the platform C
540 realloc.
541
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000542- SF bug #1232517: An overflow error was not detected properly when
543 attempting to convert a large float to an int in os.utime().
544
Raymond Hettinger3296e692005-06-29 23:29:56 +0000545- SF bug #1224347: hex longs now print with lowercase letters just
546 like their int counterparts.
547
Michael W. Hudson188d4362005-06-20 16:52:57 +0000548- SF bug #1163563: the original fix for bug #1010677 ("thread Module
549 Breaks PyGILState_Ensure()") broke badly in the case of multiple
550 interpreter states; back out that fix and do a better job (see
551 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
552 for a longer write-up of the problem).
553
Michael W. Hudsondf888462005-06-03 14:41:55 +0000554- SF patch #1180995: marshal now uses a binary format by default when
555 serializing floats.
556
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000557- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
558 the routines that promise to produce IEEE 754 binary representations
559 of floats now simply copy bytes around.
560
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000561- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
562 278.
563
Brett Cannonc3647ac2005-04-26 03:45:26 +0000564- patch #1109424: int, long, float, complex, and unicode now check for the
565 proper magic slot for type conversions when subclassed. Previously the
566 magic slot was ignored during conversion. Semantics now match the way
567 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000568 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000569 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000570 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000571
Barry Warsawc8d907c2005-04-19 23:43:40 +0000572- Descriptors defined in C with a PyGetSetDef structure, where the setter is
573 NULL, now raise an AttributeError when attempting to set or delete the
574 attribute. Previously a TypeError was raised, but this was inconsistent
575 with the equivalent pure-Python implementation.
576
Michael W. Hudson774479c2005-04-18 08:46:17 +0000577- It is now safe to call PyGILState_Release() before
578 PyEval_InitThreads() (note that if there is reason to believe there
579 are multiple threads around you still must call PyEval_InitThreads()
580 before using the Python API; this fix is for extension modules that
581 have no way of knowing if Python is multi-threaded yet).
582
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000583- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
584 disabled caused a crash.
585
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000586- Bug #1165306: instancemethod_new allowed the creation of a method
587 with im_class == im_self == NULL, which caused a crash when called.
588
Tim Petersecc6e6a2005-07-10 22:30:55 +0000589- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000590 fixes the crash seen in bug #1165761
591
Raymond Hettinger96229b12005-03-11 06:49:40 +0000592- Added two new builtins, any() and all().
593
Brett Cannon409d8f22005-03-05 06:47:57 +0000594- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000595 (e.g., ``class C(): pass`` is no longer a syntax error).
596 Patch #1176012 added support to the 'parser' module and 'compiler' package
597 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000598
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000599- Patch #1115086: Support PY_LONGLONG in structmember.
600
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000601- Bug #1155938: new style classes did not check that __init__() was
602 returning None.
603
Tim Petersecc6e6a2005-07-10 22:30:55 +0000604- Patch #802188: Report characters after line continuation character

610 inadvertently made inaccessible in restricted mode.
611
Tim Petersecc6e6a2005-07-10 22:30:55 +0000612- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000613 an ferror() call.
614
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000615- min() and max() now support key= arguments with the same meaning as in
616 list.sort().

628 statement occurs after anything other than a doc string.
629
Neil Schemenauercf52c072005-08-12 17:34:58 +0000630- Change the %s format specifier for str objects so that it returns a
631 unicode instance if the argument is not an instance of basestring and
632 calling __str__ on the argument returns a unicode instance.
633
Tim Petersf4e69282006-02-27 17:15:31 +0000634- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
635 current thread state when the auto-GIL-state machinery knows about
636 it (since the thread state is being deleted, continuing to remember it
637 can't help, but can hurt if another thread happens to get created with
638 the same thread id).

Raymond Hettingerb2594052004-12-05 09:25:51 +0000817- itertools.islice() now accepts None for the start and step arguments.
818 This allows islice() to work more readily with slices:

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000827Library
828-------
829
Nick Coghlan43832302006-04-23 17:04:07 +0000830- PEP 338: new module runpy defines a run_module function to support
831 executing modules which provide access to source code or a code object
832 via the PEP 302 import mechanisms.
833
Anthony Baxter93f5b932006-04-03 08:05:07 +0000834- The email module's parsedate_tz function now sets the daylight savings

842 in attribute values.
843
Anthony Baxterc51ee692006-04-01 00:57:31 +0000844- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000845 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000846 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000847 module will not be built.
848
Tim Petersc17976e2006-04-01 00:26:53 +0000849- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
850 aren't officially supported here, and trying to use them will probably
851 raise an exception some day. But dicts have been allowed, and "mostly
852 worked", so support for them won't go away without warning.
853
Georg Brandl338ef7d2006-03-31 18:42:16 +0000854- Bug #1445068: getpass.getpass() can now be given an explicit stream
855 argument to specify where to write the prompt.
856
Georg Brandl22ec80b2006-03-31 18:25:44 +0000857- Patch #1462313, bug #1443328: the pickle modules now can handle classes

872
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000873- email 4.0 package now integrated. This is largely the same as the email 3.0
874 package that was included in Python 2.3, except that PEP 8 module names are
875 now used (e.g. mail.message instead of email.Message). The MIME classes
876 have been moved to a subpackage (e.g. email.mime.text instead of
877 email.MIMEText). The old names are still supported for now. Several
878 deprecated Message methods have been removed and lots of bugs have been
879 fixed. More details can be found in the email package documentation.
880
Walter Dörwald40108c92006-03-27 08:15:44 +0000881- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
882 (a subclass of tuple) that provides incremental decoders and encoders

969
970 "The consensus of researchers in this area (at least as
971 expressed at the NIST Hash Function Workshop 10/31/05),
972 is that SHA-256 is a good choice for the time being, but
973 that research should continue, and other alternatives may
974 arise from this research. The larger SHA's also seem OK."

Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001146 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1147
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001148- Bug #1110478: Revert os.environ.update to do putenv again.
1149
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001150- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1151
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001152- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1153
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001154- Enhancements to the csv module:
1155
1156 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001157 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001158 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001159 + Dialect parameter parsing has been re-implemented to improve error
1160 reporting.
1161 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1162 dictates.
1163 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001164 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001165 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001166 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1167 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001168 + reader now allows \r characters to be quoted (previously it only allowed
1169 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001170 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001171 + Dialect classes passed to the module are no longer instantiated by
1172 the module before being parsed (the former validation scheme required
1173 this, but the mechanism was unreliable).
1174 + The dialect registry now contains instances of the internal
1175 C-coded dialect type, rather than references to python objects.
1176 + the internal c-coded dialect type is now immutable.
1177 + register_dialect now accepts the same keyword dialect specifications
1178 as the reader and writer, allowing the user to register dialects
1179 without first creating a dialect class.
1180 + a configurable limit to the size of parsed fields has been added -
1181 previously, an unmatched quote character could result in the entire
1182 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001183 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001184 the parser field size limit (returning the former limit). The initial
1185 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001186 + A line_num attribute has been added to the reader object, which tracks
1187 the number of lines read from the source iterator. This is not
1188 the same as the number of records returned, as records can span
1189 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001190 + reader and writer objects were not being registered with the cyclic-GC.
1191 This has been fixed.
1192
Brett Cannone6539c42005-01-08 02:43:53 +00001193- _DummyThread objects in the threading module now delete self.__block that is
1194 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1195 lock primitives tend to be limited in number and thus should not be wasted on
1196 a _DummyThread object. Fixes bug #1089632.
1197
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001198- The imghdr module now detects Exif files.
1199
Raymond Hettinger6065d322004-12-20 23:51:53 +00001200- StringIO.truncate() now correctly adjusts the size attribute.
1201 (Bug #951915).
1202
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001203- locale.py now uses an updated locale alias table (built using
1204 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1205 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001206 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001207
Raymond Hettinger3557f422004-12-07 12:02:02 +00001208- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1209
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001210- the pickle module no longer accepts the deprecated None option in the
1211 args tuple returned by __reduce__().
1212
Brett Cannon84667c02004-12-07 03:25:18 +00001213- optparse now optionally imports gettext. This allows its use in setup.py.
1214
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001215- the pickle module no longer uses the deprecated bin parameter.
1216
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001217- the shelve module no longer uses the deprecated binary parameter.
1218
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001219- the pstats module no longer uses the deprecated ignore() method.
1220
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001221- the filecmp module no longer uses the deprecated use_statcache argument.
1222
Raymond Hettinger664347b2004-12-04 21:21:53 +00001223- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1224 extended or overridden by subclasses. Formerly, the subclassed method would
1225 be ignored by the rest of the module. (Bug #1078905).
1226
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001227- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001228 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001229
Walter Dörwald36733692004-12-22 12:50:50 +00001230- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1231 once when a size argument is given. This prevents a buffer overflow in the
1232 tokenizer with very long source lines.
1233
Barry Warsaw538561e2006-01-01 21:48:54 +00001234- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1235 immediately after creating the object, without any intervening
1236 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001237
Skip Montanaro05885812005-01-16 20:48:27 +00001238- The reconvert.quote function can now emit triple-quoted strings. The
1239 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001240
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001241- ``UserString.MutableString`` now supports negative indices in
1242 ``__setitem__`` and ``__delitem__``
1243
Greg Ward40407942005-03-05 02:53:17 +00001244- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1245 correctly.
1246
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001247- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1248 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1249 character even if the user has passed a size parameter to get a proper
1250 line ending. Remove the special handling of a "\r\n" that has been split
1251 between two lines.
1252
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001253- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1254 about illegal code points. The codec now supports PEP 293 style error
1255 handlers.
1256
Walter Dörwald78a78b02005-09-01 12:04:29 +00001257- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001258 from the input stream, so that the output is a byte string in the correct
1259 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001260
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001261- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1262 considering it exactly like a '*'.
1263
Walter Dörwald007f8df2005-10-09 19:42:27 +00001264- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1265 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001266
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001267- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1268
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001269- Patch #1413711: Certain patterns of differences were making difflib
1270 touch the recursion limit.
1271
Walter Dörwald58917a62006-03-31 15:26:22 +00001272- Bug #947906: An object oriented interface has been added to the calendar
1273 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001274 called as a script (e.g. via ``python -mcalendar``). Localized month and
1275 weekday names can be ouput (even if an exotic encoding is used) using
1276 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001277
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001278Build
1279-----
1280
Neal Norwitz602d3392006-03-31 08:21:40 +00001281- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1282 by using -mieee gcc option.
1283
Martin v. Löwis86d66262006-02-17 08:40:11 +00001284- Patch #1432345: Make python compile on DragonFly.
1285
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001286- Build support for Win64-AMD64 was added.
1287
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001288- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1289
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001290- Patch #881820: look for openpty and forkpty also in libbsd.
1291
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001292- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1293 The zlib module is now builtin on Windows.
1294
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001295- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1296
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001297- Bug #1189330: configure did not correctly determine the necessary
1298 value of LINKCC if python was built with GCC 4.0.
1299
Trent Mick8321b422005-07-26 02:29:21 +00001300- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1301 vulnerability in zlib 1.2.1 and 1.2.2.
1302
Brett Cannon08cd5982005-04-24 22:26:38 +00001303- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1304 flags that change binary compatibility. Changes were also made to
1305 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001306 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001307
Bob Ippolitoed233462005-03-29 13:47:59 +00001308- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1309 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1310 no longer exists). This configure patch makes things right.
1311
Martin v. Löwise2713be2005-03-08 15:03:08 +00001312- Bug #1158607: Build with --disable-unicode again.
1313
Brett Cannon46d96232005-02-16 00:07:19 +00001314- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1315 defined. Discovered as a result of not being able to build on OS X.
1316
Brett Cannon516592f2004-12-07 00:42:59 +00001317- setup.py now uses the directories specified in LDFLAGS using the -L option
1318 and in CPPFLAGS using the -I option for adding library and include
1319 directories, respectively, for compiling extension modules against. This has
1320 led to the core being compiled using the values in CPPFLAGS. It also removes
1321 the need for the special-casing of both DarwinPorts and Fink for darwin since
1322 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1323 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1324 Fink, ``-I/opt/local/include`` for DarwinPorts).
1325
Brett Cannon43802422005-02-10 20:48:03 +00001326- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1327 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1328 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1329 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001331C API
1332-----
1333
Tim Petersc9d78aa2006-03-26 23:27:58 +00001334- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1335 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1336 is obtained via the ``PyObject_`` family, it must be released via the
1337 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1338 always been officially true, but when Python's small-object allocator was
1339 introduced, an attempt was made to cater to a few extension modules
1340 discovered at the time that obtained memory via ``PyObject_New`` but
1341 released it via ``PyMem_DEL``. It's years later, and if such code still
1342 exists it will fail now (probably with segfaults, but calling wrong
1343 low-level memory management functions can yield many symptoms).
1344
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001345- Added a C API for set and frozenset objects.
1346
Raymond Hettinger66517482004-12-03 11:45:13 +00001347- Removed PyRange_New().
1348
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001349- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1350 mapping argument now. This string is used as a mapping table. Byte values
1351 greater than the length of the string and 0xFFFE are treated as undefined
1352 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001359
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001360- Patch #1276356: New resource "urlfetch" is implemented. This enables

1412 vimrc to it (was previous up a level).
1413
Georg Brandl56897312005-08-24 18:32:30 +00001414- Added two new files to Tools/scripts: pysource.py, which recursively
