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
Bob Ippolito7298f272006-05-23 18:43:47 +000088- Patch #1281707: speed up gzip.readline.
89
Georg Brandlb89316f2006-05-17 15:51:16 +000090- Patch #1180296: Two new functions were added to the locale module:
91 format_string() to get the effect of "format % items" but locale-aware,
92 and currency() to format a monetary number with currency sign.
93
Georg Brandle3a25832006-05-17 14:56:04 +000094- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
95 and several features added, such as speed and geometry control.
96
Georg Brandl49c8f4c2006-05-15 19:30:35 +000097- Patch #1488881: add support for external file objects in bz2 compressed
98 tarfiles.
99
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000100- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
101 stdout arguments, making it possible to redirect input and output
102 for remote debugging.
103
104- Patch #1484695: Update the tarfile module to version 0.8. This fixes
105 a couple of issues, notably handling of long file names using the
106 GNU LONGNAME extension.
107
108- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
109 new flag when ``name`` is already the name of an option flag.
110
111- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
112 package.
113
114- Patch #1472854: make the rlcompleter.Completer class usable on non-
115 UNIX platforms.
116
117- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Martin v. Löwisa43190b2006-05-22 09:15:18 +0000122- Patch #1492356: Port to Windows CE.
123
Neal Norwitz58e28882006-05-19 07:00:58 +0000124- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.

140What's New in Python 2.5 alpha 2?
141=================================
142
143*Release date: 27-APR-2006*
144
145Core and builtins
146-----------------
147
Thomas Heller1b046642006-04-18 18:51:06 +0000148- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
149 by converting these apis from macros into exported functions again:
150
151 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
152 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
153 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
154 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
155 PyRun_String Py_CompileString
156
Martin v. Löwis45294a92006-04-18 06:24:08 +0000157- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
158
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000159- All uses of PyStructSequence_InitType have been changed to initialize
160 the type objects only once, even if the interpreter is initialized
161 multiple times.
162
Neal Norwitz61546162006-04-14 05:20:28 +0000163- Bug #1454485, array.array('u') could crash the interpreter. This was
164 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
165 to unicode when it didn't make sense. 'u#' now requires a unicode string.
166
167- Py_UNICODE is unsigned. It was always documented as unsigned, but
168 due to a bug had a signed value in previous versions.
169
Tim Peters3a5e8b12006-04-11 01:44:07 +0000170- Patch #837242: ``id()`` of any Python object always gives a positive
171 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
172 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000173 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000174 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000175
Tim Peters3a5e8b12006-04-11 01:44:07 +0000176 def __hash__(self):
177 return id(self) # WRONG
178
179 because a hash result must be a (short) Python int but it was always
180 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000181 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000182 was always usable as a hash value before this patch. That's no longer
183 necessarily so.
184
185- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000186 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000187 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000188 #1454844)
189
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000190- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
191 involving generators that have paused outside of any ``try`` or ``with``
192 blocks. (In 2.5a1, a paused generator that was part of a reference
193 cycle could not be garbage collected, regardless of whether it was
194 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +0000195
Anthony Baxter51bcb682006-04-05 14:51:42 +0000196Extension Modules

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000199- Patch #1191065: Fix preprocessor problems on systems where recvfrom
200 is a macro.
201
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000202- Bug #1467952: os.listdir() now correctly raises an error if readdir()
203 fails with an error condition.
204
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000205- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
206
207- Bug #1117761: bsddb.*open() no longer raises an exception when using
208 the cachesize parameter.
209
210- Bug #1149413: bsddb.*open() no longer raises an exception when using
211 a temporary db (file=None) with the 'n' flag to truncate on open.
212
213- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
214 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000215
Armin Rigoa9017c32006-04-19 11:50:27 +0000216- Patch #1062014: AF_UNIX sockets under Linux have a special
217 abstract namespace that is now fully supported.
218
Anthony Baxter51bcb682006-04-05 14:51:42 +0000219Library
220-------
221
Tim Peters711bf302006-04-25 03:31:36 +0000222- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
223 a doctest to be skipped (the code is not run, and the expected output
224 or exception is ignored).
225
Nick Coghlanda2268f2006-04-24 04:37:15 +0000226- Fixed contextlib.nested to cope with exceptions being raised and
227 caught inside exit handlers.
228
Greg Wardab05edc2006-04-23 03:47:58 +0000229- Updated optparse module to Optik 1.5.1 (allow numeric constants in
230 hex, octal, or binary; add ``append_const`` action; keep going if
231 gettext cannot be imported; added ``OptionParser.destroy()`` method;
232 added ``epilog`` for better help generation).
233
Tim Peters21fbd572006-04-21 21:18:10 +0000234- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
235 called from a thread spawned as a side effect of importing a module.
236
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000237- The pydoc module now supports documenting packages contained in
238 .zip or .egg files.
239
240- The pkgutil module now has several new utility functions, such
241 as ``walk_packages()`` to support working with packages that are either
242 in the filesystem or zip files.
243
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000244- The mailbox module can now modify and delete messages from
245 mailboxes, in addition to simply reading them. Thanks to Gregory
246 K. Johnson for writing the code, and to the 2005 Google Summer of
247 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000248
Tim Petersc7605f22006-04-17 21:12:33 +0000249- The ``__del__`` method of class ``local`` in module ``_threading_local``
250 returned before accomplishing any of its intended cleanup.
251

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000256- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
257
Anthony Baxtere29002c2006-04-12 12:07:31 +0000258- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
259 Windows. Bug #1469163.
260
Phillip J. Eby47032112006-04-11 01:07:43 +0000261- The warnings, linecache, inspect, traceback, site, and doctest modules
262 were updated to work correctly with modules imported from zipfiles or
263 via other PEP 302 __loader__ objects.
264
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000265- Patch #1467770: Reduce usage of subprocess._active to processes which
266 the application hasn't waited on.
267

277
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000278- The Makefile now has a reindent target, which runs reindent.py on
279 the library.

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000285- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
286 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000287 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000288 CXX from --with-cxx-main, see description in README.
289

305
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000306- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
307 it separately and by hand. It also wasn't cleaning up its changes to
308 the current Decimal context.
309
Thomas Woutersabd08882006-04-26 15:53:30 +0000310- regrtest.py now has a -M option to run tests that test the new limits of
311 containers, on 64-bit architectures. Running these tests is only sensible
312 on 64-bit machines with more than two gigabytes of memory. The argument
313 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000339Core and builtins
340-----------------
341
Nick Coghlan43832302006-04-23 17:04:07 +0000342- PEP 338: -m command line switch now delegates to runpy.run_module
343 allowing it to support modules in packages and zipfiles
344
Martin v. Löwisc661b882006-04-20 04:54:23 +0000345- On Windows, .DLL is not an accepted file name extension for
346 extension modules anymore; extensions are only found if they
347 end in .PYD.
348
Martin v. Löwisea62d252006-04-03 10:56:49 +0000349- Bug #1421664: sys.stderr.encoding is now set to the same value as
350 sys.stdout.encoding.
351
Neal Norwitz92e212f2006-04-03 04:48:37 +0000352- __import__ accepts keyword arguments.
353
Georg Brandlccadf842006-03-31 18:54:53 +0000354- Patch #1460496: round() now accepts keyword arguments.
355
Anthony Baxter262c00a2006-03-30 10:53:17 +0000356- Fixed bug #1459029 - unicode reprs were double-escaped.
357
Hye-Shik Changd478f342006-03-23 12:32:36 +0000358- Patch #1396919: The system scope threads are reenabled on FreeBSD
359 5.4 and later versions.
360
Neal Norwitze98ccf62006-03-23 05:39:47 +0000361- Bug #1115379: Compiling a Unicode string with an encoding declaration
362 now gives a SyntaxError.
363
Georg Brandlabd1ff82006-03-18 07:59:59 +0000364- Previously, Python code had no easy way to access the contents of a
365 cell object. Now, a ``cell_contents`` attribute has been added
366 (closes patch #1170323).
367
Tim Peterscf79aac2006-03-16 01:14:46 +0000368- Patch #1123430: Python's small-object allocator now returns an arena to
369 the system ``free()`` when all memory within an arena becomes unused
370 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
371 freed. Some applications will see a drop in virtual memory size now,
372 especially long-running applications that, from time to time, temporarily
373 use a large number of small objects. Note that when Python returns an
374 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000375 platform C library will in turn return that memory to the operating system.
376 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000377 appears to be effective at least on Microsoft C and gcc-based systems.
378 Thanks to Evan Jones for hard work and patience.
379
Georg Brandl533ff6f2006-03-08 18:09:27 +0000380- Patch #1434038: property() now uses the getter's docstring if there is
381 no "doc" argument given. This makes it possible to legitimately use
382 property() as a decorator to produce a read-only property.
383
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000384- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
385 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
386 of requiring an int or long in slicing and a few other contexts, enabling
387 other objects (e.g. Numeric Python's integers) to be used as slice indices.
388
Neal Norwitz995acdf2006-03-07 05:01:00 +0000389- Fixed various bugs reported by Coverity's Prevent tool.
390
Brett Cannonbf364092006-03-01 04:25:17 +0000391- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
392 new exception base class, BaseException, which has a new message attribute.
393 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
394 Raising a string exception now raises a DeprecationWarning.
395
Thomas Woutersfb609f42006-02-28 16:37:25 +0000396- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
397 explicitly relative, using 'from .module import name' to mean 'from the same
398 package as this module is in. Imports without dots still default to the
399 old relative-then-absolute, unless 'from __future__ import
400 absolute_import' is used.
401
Brett Cannona7446e32006-02-27 23:39:10 +0000402- Properly check if 'warnings' raises an exception (usually when a filter set
403 to "error" is triggered) when raising a warning for raising string
404 exceptions.
405
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000406- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000407 The name was removed from Include/code.h.
408
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000409- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000410
Guido van Rossum1968ad32006-02-25 22:38:04 +0000411- Patch 1433928:
412 - The copy module now "copies" function objects (as atomic objects).
413 - dict.__getitem__ now looks for a __missing__ hook before raising
414 KeyError.
415
Tim Peters84ef21c2006-02-28 20:39:06 +0000416- PEP 343: with statement implemented. Needs ``from __future__ import
417 with_statement``. Use of 'with' as a variable will generate a warning.
418 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000419 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000420 The following objects have __context__ methods:
421 - The built-in file type.
422 - The thread.LockType type.
423 - The following types defined by the threading module:
424 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
425 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000426
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000427- Fix the encodings package codec search function to only search
428 inside its own package. Fixes problem reported in patch #1433198.
429
430 Note: Codec packages should implement and register their own
431 codec search function. PEP 100 has the details.
432
Martin v. Löwis18e16552006-02-15 17:27:45 +0000433- PEP 353: Using ssize_t as the index type.
434
Neal Norwitzfc76d632006-01-10 06:03:13 +0000435- Patch #1400181, fix unicode string formatting to not use the locale.
436 This is how string objects work. u'%f' could use , instead of .
437 for the decimal point. Now both strings and unicode always use periods.
438
Neal Norwitz671b9e32006-01-09 07:07:12 +0000439- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
440 configure would break checking curses.h.
441
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000442- Bug #959576: The pwd module is now builtin. This allows Python to be
443 built on UNIX platforms without $HOME set.
444
Neal Norwitzc10978f2005-12-19 06:07:16 +0000445- Bug #1072182, fix some potential problems if characters are signed.
446
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000447- Bug #889500, fix line number on SyntaxWarning for global declarations.
448
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000449- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
450
Neal Norwitze7214a12005-12-18 05:03:17 +0000451- Support for converting hex strings to floats no longer works.
452 This was not portable. float('0x3') now raises a ValueError.
453
Barry Warsaw2a38a862005-12-18 01:27:35 +0000454- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000455 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000456 is now displayed in interactive prompt banner.
457
Georg Brandlfa166682005-12-17 21:45:17 +0000458- Implementation of PEP 341 - Unification of try/except and try/finally.
459 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000460 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000461
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000462- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
463 now encodes backslash correctly.
464
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000465- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
466
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000467- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000468 and long longs.
469
Neal Norwitz67715f02005-11-09 06:59:35 +0000470- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000471 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000472 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000473
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000474- Replaced most Unicode charmap codecs with new ones using the
475 new Unicode translate string feature in the builtin charmap
476 codec; the codecs were created from the mapping tables available
477 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
478 encodings now include a mapping for the Apple logo)
479
Tim Peterse3547fd2005-12-16 23:13:57 +0000480- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000481
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000482- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000483
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000484- A new AST parser implementation was completed. The abstract
485 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000486 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000487
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000488- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000489 The following code now raises a SyntaxError: foo(a = i for i in range(10))
490
Neal Norwitz708e51a2005-10-03 04:48:15 +0000491- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
492
Neal Norwitz11bd1192005-10-03 00:54:56 +0000493- SF Bug #887946: fix segfault when redirecting stdin from a directory.
494 Provide a warning when a directory is passed on the command line.
495
Neal Norwitz40d37812005-10-02 01:48:49 +0000496- Fix segfault with invalid coding.
497
498- SF bug #772896: unknown encoding results in MemoryError.
499
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000500- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000501 supported a __len__() method which evaluated to False when the iterator
502 was empty.
503
Guido van Rossum630db602005-09-20 18:49:54 +0000504- On 64-bit platforms, when __len__() returns a value that cannot be
505 represented as a C int, raise OverflowError.
506
Skip Montanarof8948ca2005-09-19 03:54:46 +0000507- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000508 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000509
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000510- SF bug #893549: parsing keyword arguments was broken with a few format
511 codes.
512
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000513- Changes donated by Elemental Security to make it work on AIX 5.3
514 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
515 bug #105470: test_pwd fails on 64bit system (Opteron).
516
Guido van Rossum539c6622005-09-14 17:49:54 +0000517- Changes donated by Elemental Security to make it work on HP-UX 11 on
518 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
519
Georg Brandl4550b8d2005-08-26 06:43:52 +0000520- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000521 (fixes bug #1119418).
522
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000523- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
524
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000525- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
526 exceptions that cause a function to exit.
527
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000528- The implementation of set() and frozenset() was revised to use its
529 own internal data structure. Memory consumption is reduced by 1/3
530 and there are modest speed-ups as well. The API is unchanged.
531
Tim Petersde7990b2005-07-17 23:45:23 +0000532- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
533
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000534- SF bug #1229429: PyObject_CallMethod failed to decrement some
535 reference counts in some error exit cases.
536
Tim Petersecc6e6a2005-07-10 22:30:55 +0000537- SF bug #1185883: Python's small-object memory allocator took over
538 a block managed by the platform C library whenever a realloc specified
539 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000540 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000541 portable way to copy data from the C-managed block into Python's
542 small-object space without risking a memory fault. Python's small-object
543 realloc now leaves such blocks under the control of the platform C
544 realloc.
545
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000546- SF bug #1232517: An overflow error was not detected properly when
547 attempting to convert a large float to an int in os.utime().
548
Raymond Hettinger3296e692005-06-29 23:29:56 +0000549- SF bug #1224347: hex longs now print with lowercase letters just
550 like their int counterparts.
551
Michael W. Hudson188d4362005-06-20 16:52:57 +0000552- SF bug #1163563: the original fix for bug #1010677 ("thread Module
553 Breaks PyGILState_Ensure()") broke badly in the case of multiple
554 interpreter states; back out that fix and do a better job (see
555 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
556 for a longer write-up of the problem).
557
Michael W. Hudsondf888462005-06-03 14:41:55 +0000558- SF patch #1180995: marshal now uses a binary format by default when
559 serializing floats.
560
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000561- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
562 the routines that promise to produce IEEE 754 binary representations
563 of floats now simply copy bytes around.
564
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000565- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
566 278.
567
Brett Cannonc3647ac2005-04-26 03:45:26 +0000568- patch #1109424: int, long, float, complex, and unicode now check for the
569 proper magic slot for type conversions when subclassed. Previously the
570 magic slot was ignored during conversion. Semantics now match the way
571 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000572 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000573 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000574 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000575
Barry Warsawc8d907c2005-04-19 23:43:40 +0000576- Descriptors defined in C with a PyGetSetDef structure, where the setter is
577 NULL, now raise an AttributeError when attempting to set or delete the
578 attribute. Previously a TypeError was raised, but this was inconsistent
579 with the equivalent pure-Python implementation.
580
Michael W. Hudson774479c2005-04-18 08:46:17 +0000581- It is now safe to call PyGILState_Release() before
582 PyEval_InitThreads() (note that if there is reason to believe there
583 are multiple threads around you still must call PyEval_InitThreads()
584 before using the Python API; this fix is for extension modules that
585 have no way of knowing if Python is multi-threaded yet).
586
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000587- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
588 disabled caused a crash.
589
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000590- Bug #1165306: instancemethod_new allowed the creation of a method
591 with im_class == im_self == NULL, which caused a crash when called.
592
Tim Petersecc6e6a2005-07-10 22:30:55 +0000593- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000594 fixes the crash seen in bug #1165761
595
Raymond Hettinger96229b12005-03-11 06:49:40 +0000596- Added two new builtins, any() and all().
597
Brett Cannon409d8f22005-03-05 06:47:57 +0000598- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000599 (e.g., ``class C(): pass`` is no longer a syntax error).
600 Patch #1176012 added support to the 'parser' module and 'compiler' package
601 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000602
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000603- Patch #1115086: Support PY_LONGLONG in structmember.
604
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000605- Bug #1155938: new style classes did not check that __init__() was
606 returning None.
607
Tim Petersecc6e6a2005-07-10 22:30:55 +0000608- Patch #802188: Report characters after line continuation character

Tim Petersecc6e6a2005-07-10 22:30:55 +0000616- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000617 an ferror() call.
618
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000619- min() and max() now support key= arguments with the same meaning as in

632 statement occurs after anything other than a doc string.
633
Neil Schemenauercf52c072005-08-12 17:34:58 +0000634- Change the %s format specifier for str objects so that it returns a
635 unicode instance if the argument is not an instance of basestring and
636 calling __str__ on the argument returns a unicode instance.
637
Tim Petersf4e69282006-02-27 17:15:31 +0000638- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
639 current thread state when the auto-GIL-state machinery knows about
640 it (since the thread state is being deleted, continuing to remember it
641 can't help, but can hurt if another thread happens to get created with
642 the same thread id).

Raymond Hettingerb2594052004-12-05 09:25:51 +0000821- itertools.islice() now accepts None for the start and step arguments.
822 This allows islice() to work more readily with slices:

830
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000831Library
832-------
833
Nick Coghlan43832302006-04-23 17:04:07 +0000834- PEP 338: new module runpy defines a run_module function to support
835 executing modules which provide access to source code or a code object
836 via the PEP 302 import mechanisms.
837

846 in attribute values.
847
Anthony Baxterc51ee692006-04-01 00:57:31 +0000848- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000849 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000850 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000851 module will not be built.
852
Tim Petersc17976e2006-04-01 00:26:53 +0000853- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
854 aren't officially supported here, and trying to use them will probably
855 raise an exception some day. But dicts have been allowed, and "mostly
856 worked", so support for them won't go away without warning.
857
Georg Brandl338ef7d2006-03-31 18:42:16 +0000858- Bug #1445068: getpass.getpass() can now be given an explicit stream
859 argument to specify where to write the prompt.
860
Georg Brandl22ec80b2006-03-31 18:25:44 +0000861- Patch #1462313, bug #1443328: the pickle modules now can handle classes

876
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000877- email 4.0 package now integrated. This is largely the same as the email 3.0
878 package that was included in Python 2.3, except that PEP 8 module names are
879 now used (e.g. mail.message instead of email.Message). The MIME classes
880 have been moved to a subpackage (e.g. email.mime.text instead of
881 email.MIMEText). The old names are still supported for now. Several
882 deprecated Message methods have been removed and lots of bugs have been
883 fixed. More details can be found in the email package documentation.
884
Walter Dörwald40108c92006-03-27 08:15:44 +0000885- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object

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

Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001150 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1151
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001152- Bug #1110478: Revert os.environ.update to do putenv again.
1153
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001154- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1155
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001156- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1157
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001158- Enhancements to the csv module:
1159
1160 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001161 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001162 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001163 + Dialect parameter parsing has been re-implemented to improve error
1164 reporting.
1165 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1166 dictates.
1167 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001168 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001169 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001170 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1171 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001172 + reader now allows \r characters to be quoted (previously it only allowed
1173 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001174 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001175 + Dialect classes passed to the module are no longer instantiated by
1176 the module before being parsed (the former validation scheme required
1177 this, but the mechanism was unreliable).
1178 + The dialect registry now contains instances of the internal
1179 C-coded dialect type, rather than references to python objects.
1180 + the internal c-coded dialect type is now immutable.
1181 + register_dialect now accepts the same keyword dialect specifications
1182 as the reader and writer, allowing the user to register dialects
1183 without first creating a dialect class.
1184 + a configurable limit to the size of parsed fields has been added -
1185 previously, an unmatched quote character could result in the entire
1186 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001187 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001188 the parser field size limit (returning the former limit). The initial
1189 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001190 + A line_num attribute has been added to the reader object, which tracks
1191 the number of lines read from the source iterator. This is not
1192 the same as the number of records returned, as records can span
1193 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001194 + reader and writer objects were not being registered with the cyclic-GC.
1195 This has been fixed.
1196
Brett Cannone6539c42005-01-08 02:43:53 +00001197- _DummyThread objects in the threading module now delete self.__block that is
1198 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1199 lock primitives tend to be limited in number and thus should not be wasted on
1200 a _DummyThread object. Fixes bug #1089632.
1201
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001202- The imghdr module now detects Exif files.
1203
Raymond Hettinger6065d322004-12-20 23:51:53 +00001204- StringIO.truncate() now correctly adjusts the size attribute.
1205 (Bug #951915).
1206
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001207- locale.py now uses an updated locale alias table (built using
1208 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1209 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001210 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001211
Raymond Hettinger3557f422004-12-07 12:02:02 +00001212- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1213
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001214- the pickle module no longer accepts the deprecated None option in the
1215 args tuple returned by __reduce__().
1216
Brett Cannon84667c02004-12-07 03:25:18 +00001217- optparse now optionally imports gettext. This allows its use in setup.py.
1218
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001219- the pickle module no longer uses the deprecated bin parameter.
1220
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001221- the shelve module no longer uses the deprecated binary parameter.
1222
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001223- the pstats module no longer uses the deprecated ignore() method.
1224
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001225- the filecmp module no longer uses the deprecated use_statcache argument.
1226
Raymond Hettinger664347b2004-12-04 21:21:53 +00001227- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1228 extended or overridden by subclasses. Formerly, the subclassed method would
1229 be ignored by the rest of the module. (Bug #1078905).
1230
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001231- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001232 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001233
Walter Dörwald36733692004-12-22 12:50:50 +00001234- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1235 once when a size argument is given. This prevents a buffer overflow in the
1236 tokenizer with very long source lines.
1237
Barry Warsaw538561e2006-01-01 21:48:54 +00001238- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1239 immediately after creating the object, without any intervening
1240 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001241
Skip Montanaro05885812005-01-16 20:48:27 +00001242- The reconvert.quote function can now emit triple-quoted strings. The
1243 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001244
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001245- ``UserString.MutableString`` now supports negative indices in
1246 ``__setitem__`` and ``__delitem__``
1247
Greg Ward40407942005-03-05 02:53:17 +00001248- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1249 correctly.
1250
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001251- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1252 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1253 character even if the user has passed a size parameter to get a proper
1254 line ending. Remove the special handling of a "\r\n" that has been split
1255 between two lines.
1256
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001257- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1258 about illegal code points. The codec now supports PEP 293 style error
1259 handlers.
1260
Walter Dörwald78a78b02005-09-01 12:04:29 +00001261- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001262 from the input stream, so that the output is a byte string in the correct
1263 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001264
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001265- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1266 considering it exactly like a '*'.
1267
Walter Dörwald007f8df2005-10-09 19:42:27 +00001268- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1269 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001270
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001271- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1272
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001273- Patch #1413711: Certain patterns of differences were making difflib
1274 touch the recursion limit.
1275
Walter Dörwald58917a62006-03-31 15:26:22 +00001276- Bug #947906: An object oriented interface has been added to the calendar
1277 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001278 called as a script (e.g. via ``python -mcalendar``). Localized month and
1279 weekday names can be ouput (even if an exotic encoding is used) using
1280 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001281
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001282Build
1283-----
1284
Neal Norwitz602d3392006-03-31 08:21:40 +00001285- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1286 by using -mieee gcc option.
1287
Martin v. Löwis86d66262006-02-17 08:40:11 +00001288- Patch #1432345: Make python compile on DragonFly.
1289
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001290- Build support for Win64-AMD64 was added.
1291
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001292- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1293
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001294- Patch #881820: look for openpty and forkpty also in libbsd.
1295
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001296- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1297 The zlib module is now builtin on Windows.
1298
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001299- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1300
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001301- Bug #1189330: configure did not correctly determine the necessary
1302 value of LINKCC if python was built with GCC 4.0.
1303
Trent Mick8321b422005-07-26 02:29:21 +00001304- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1305 vulnerability in zlib 1.2.1 and 1.2.2.
1306
Brett Cannon08cd5982005-04-24 22:26:38 +00001307- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1308 flags that change binary compatibility. Changes were also made to
1309 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001310 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001311
Bob Ippolitoed233462005-03-29 13:47:59 +00001312- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1313 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1314 no longer exists). This configure patch makes things right.
1315
Martin v. Löwise2713be2005-03-08 15:03:08 +00001316- Bug #1158607: Build with --disable-unicode again.
1317
Brett Cannon46d96232005-02-16 00:07:19 +00001318- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1319 defined. Discovered as a result of not being able to build on OS X.
1320
Brett Cannon516592f2004-12-07 00:42:59 +00001321- setup.py now uses the directories specified in LDFLAGS using the -L option
1322 and in CPPFLAGS using the -I option for adding library and include
1323 directories, respectively, for compiling extension modules against. This has
1324 led to the core being compiled using the values in CPPFLAGS. It also removes
1325 the need for the special-casing of both DarwinPorts and Fink for darwin since
1326 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1327 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1328 Fink, ``-I/opt/local/include`` for DarwinPorts).
1329
Brett Cannon43802422005-02-10 20:48:03 +00001330- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1331 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1332 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1333 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001335C API
1336-----
1337
Tim Petersc9d78aa2006-03-26 23:27:58 +00001338- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1339 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1340 is obtained via the ``PyObject_`` family, it must be released via the
1341 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1342 always been officially true, but when Python's small-object allocator was
1343 introduced, an attempt was made to cater to a few extension modules
1344 discovered at the time that obtained memory via ``PyObject_New`` but
1345 released it via ``PyMem_DEL``. It's years later, and if such code still
1346 exists it will fail now (probably with segfaults, but calling wrong
1347 low-level memory management functions can yield many symptoms).
1348
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001349- Added a C API for set and frozenset objects.
1350
Raymond Hettinger66517482004-12-03 11:45:13 +00001351- Removed PyRange_New().
1352
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001353- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1354 mapping argument now. This string is used as a mapping table. Byte values
1355 greater than the length of the string and 0xFFFE are treated as undefined
1356 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001363
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001364- Patch #1276356: New resource "urlfetch" is implemented. This enables
