Nick Coghlanc649ec52006-05-29 12:43:05 +00007What's New in Python 2.5 beta 1?
Anthony Baxter51bcb682006-04-05 14:51:42 +00008=================================
9
Nick Coghlanc649ec52006-05-29 12:43:05 +000010*Release date: XX-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Georg Brandlb7c8f542006-05-27 12:30:25 +000015- Builtin exceptions are now full-blown new-style classes instead of
16 instances pretending to be classes, which speeds up exception handling
17 by about 80% in comparison to 2.5a2.
18
Martin v. Löwisd004fc82006-05-27 08:36:52 +000019- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
20 Unicode 4.1.
21
Georg Brandlf4ef1162006-05-26 18:03:31 +000022- Patch #921466: sys.path_importer_cache is now used to cache valid and
23 invalid file paths for the built-in import machinery which leads to
24 fewer open calls on startup.
25
Tim Peters696cf432006-05-24 21:10:40 +000026- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
27 of-2 bases. The largest speedup is for inputs with about 1000 decimal
28 digits. Conversion from non-power-of-2 bases remains quadratic-time in
29 the number of input digits (it was and remains linear-time for bases
30 2, 4, 8, 16 and 32).
31
Tim Petersb713ec22006-05-23 18:45:30 +000032- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
33 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
34 an integer close to ``sys.maxint``. This was repaired by patch
35 #1335972, which also gives a nice speedup.
36
Richard Jonescebbefc2006-05-23 18:28:17 +000037- Patch #1337051: reduced size of frame objects.
38
39- PyErr_NewException now accepts a tuple of base classes as its
40 "base" parameter.
41
Richard Jones7c88dcc2006-05-23 10:37:38 +000042- Patch #876206: function call speedup by retaining allocated frame
43 objects.
44
Georg Brandl7b90e162006-05-18 07:01:27 +000045- Bug #1462152: file() now checks more thoroughly for invalid mode
46 strings and removes a possible "U" before passing the mode to the
47 C library function.
48
Neal Norwitz1004a532006-05-15 07:17:23 +000049- Patch #1488312, Fix memory alignment problem on SPARC in unicode
50
Neal Norwitz373f0a72006-05-15 07:04:36 +000051- Bug #1487966: Fix SystemError with conditional expression in assignment
52
Martin v. Löwis879768d2006-05-11 13:28:43 +000053- WindowsError now has two error code attributes: errno, which carries
54 the error values from errno.h, and winerror, which carries the error
55 values from winerror.h. Previous versions put the winerror.h values
56 (from GetLastError()) into the errno attribute.
57
Martin v. Löwis77736712006-05-04 05:51:03 +000058- Patch #1475845: Raise IndentationError for unexpected indent.
59
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000060- Patch #1479181: split open() and file() from being aliases for each other.
61
Neal Norwitz7a5fc282006-05-15 06:48:14 +000062Extension Modules
63-----------------
64
Nick Coghlanc649ec52006-05-29 12:43:05 +000065- Patch #1478788 (modified version): The functional extension module has
66 been renamed to _functools and a functools Python wrapper module added.
67 This provides a home for additional function related utilities that are
68 not specifically about functional programming. See PEP 309.
69
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000070- Patch #1493701: performance enhancements for struct module.
71
Georg Brandl378d5922006-05-17 14:26:50 +000072- Patch #1490224: time.altzone is now set correctly on Cygwin.
73
Georg Brandl8d3342b2006-05-16 07:38:27 +000074- Patch #1435422: zlib's compress and decompress objects now have a
75 copy() method.
76
Neal Norwitz7a5fc282006-05-15 06:48:14 +000077- On Win32, os.listdir now supports arbitrarily-long Unicode path names
78 (up to the system limit of 32K characters).
79
80- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
81 As a result, these functions now raise WindowsError instead of OSError.
82
Tim Peters7a822da2006-05-25 21:50:17 +000083- ``time.clock()`` on Win64 should use the high-performance Windows
84 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
85 Windows platforms).
86
Neal Norwitz7a5fc282006-05-15 06:48:14 +000087- Calling Tk_Init twice is refused if the first call failed as that
88 may deadlock.
89
Nick Coghlanc649ec52006-05-29 12:43:05 +000090
Neal Norwitz7a5fc282006-05-15 06:48:14 +000091Library
92-------
93
Georg Brandl2b330372006-05-28 20:23:12 +000094- Patch #1496206: improve urllib2 handling of passwords with respect to
95 default HTTP and HTTPS ports.
96
George Yoshidaf3c65de2006-05-28 16:39:09 +000097- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
98
Bob Ippolito7298f272006-05-23 18:43:47 +000099- Patch #1281707: speed up gzip.readline.
100
Georg Brandlb89316f2006-05-17 15:51:16 +0000101- Patch #1180296: Two new functions were added to the locale module:
102 format_string() to get the effect of "format % items" but locale-aware,
103 and currency() to format a monetary number with currency sign.
104
Georg Brandle3a25832006-05-17 14:56:04 +0000105- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
106 and several features added, such as speed and geometry control.
107
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000108- Patch #1488881: add support for external file objects in bz2 compressed
109 tarfiles.
110
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000111- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
112 stdout arguments, making it possible to redirect input and output
113 for remote debugging.
114
115- Patch #1484695: Update the tarfile module to version 0.8. This fixes
116 a couple of issues, notably handling of long file names using the
117 GNU LONGNAME extension.
118
119- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
120 new flag when ``name`` is already the name of an option flag.
121
122- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
123 package.
124
125- Patch #1472854: make the rlcompleter.Completer class usable on non-
126 UNIX platforms.
127
128- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000153What's New in Python 2.5 alpha 2?
154=================================
155
156*Release date: 27-APR-2006*
157
158Core and builtins
159-----------------
160
Thomas Heller1b046642006-04-18 18:51:06 +0000161- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
162 by converting these apis from macros into exported functions again:
163
164 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
165 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
166 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
167 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
168 PyRun_String Py_CompileString
169
Martin v. Löwis45294a92006-04-18 06:24:08 +0000170- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
171
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000172- All uses of PyStructSequence_InitType have been changed to initialize
173 the type objects only once, even if the interpreter is initialized
174 multiple times.
175
Neal Norwitz61546162006-04-14 05:20:28 +0000176- Bug #1454485, array.array('u') could crash the interpreter. This was
177 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
178 to unicode when it didn't make sense. 'u#' now requires a unicode string.
179
180- Py_UNICODE is unsigned. It was always documented as unsigned, but
181 due to a bug had a signed value in previous versions.
182
Tim Peters3a5e8b12006-04-11 01:44:07 +0000183- Patch #837242: ``id()`` of any Python object always gives a positive
184 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
185 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000186 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000187 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000188
Tim Peters3a5e8b12006-04-11 01:44:07 +0000189 def __hash__(self):
190 return id(self) # WRONG
191
192 because a hash result must be a (short) Python int but it was always
193 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000194 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000195 was always usable as a hash value before this patch. That's no longer
196 necessarily so.
197
198- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000199 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000200 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000201 #1454844)
202
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000203- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
204 involving generators that have paused outside of any ``try`` or ``with``
205 blocks. (In 2.5a1, a paused generator that was part of a reference
206 cycle could not be garbage collected, regardless of whether it was
207 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000209Extension Modules
210-----------------
211
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000212- Patch #1191065: Fix preprocessor problems on systems where recvfrom
213 is a macro.
214
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000215- Bug #1467952: os.listdir() now correctly raises an error if readdir()
216 fails with an error condition.
217
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000218- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
219
220- Bug #1117761: bsddb.*open() no longer raises an exception when using
221 the cachesize parameter.
222
223- Bug #1149413: bsddb.*open() no longer raises an exception when using
224 a temporary db (file=None) with the 'n' flag to truncate on open.
225
226- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
227 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000228
Armin Rigoa9017c32006-04-19 11:50:27 +0000229- Patch #1062014: AF_UNIX sockets under Linux have a special
230 abstract namespace that is now fully supported.
231

233-------
234
Tim Peters711bf302006-04-25 03:31:36 +0000235- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
236 a doctest to be skipped (the code is not run, and the expected output
237 or exception is ignored).
238
Nick Coghlanda2268f2006-04-24 04:37:15 +0000239- Fixed contextlib.nested to cope with exceptions being raised and
240 caught inside exit handlers.
241
Greg Wardab05edc2006-04-23 03:47:58 +0000242- Updated optparse module to Optik 1.5.1 (allow numeric constants in
243 hex, octal, or binary; add ``append_const`` action; keep going if
244 gettext cannot be imported; added ``OptionParser.destroy()`` method;
245 added ``epilog`` for better help generation).
246
Tim Peters21fbd572006-04-21 21:18:10 +0000247- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
248 called from a thread spawned as a side effect of importing a module.
249
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000250- The pydoc module now supports documenting packages contained in
251 .zip or .egg files.
252
253- The pkgutil module now has several new utility functions, such
254 as ``walk_packages()`` to support working with packages that are either
255 in the filesystem or zip files.
256
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000257- The mailbox module can now modify and delete messages from
258 mailboxes, in addition to simply reading them. Thanks to Gregory
259 K. Johnson for writing the code, and to the 2005 Google Summer of
260 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000261
Tim Petersc7605f22006-04-17 21:12:33 +0000262- The ``__del__`` method of class ``local`` in module ``_threading_local``
263 returned before accomplishing any of its intended cleanup.
264
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000265- Patch #790710: Add breakpoint command lists in pdb.
266

Anthony Baxtere29002c2006-04-12 12:07:31 +0000271- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
272 Windows. Bug #1469163.
273
Phillip J. Eby47032112006-04-11 01:07:43 +0000274- The warnings, linecache, inspect, traceback, site, and doctest modules
275 were updated to work correctly with modules imported from zipfiles or
276 via other PEP 302 __loader__ objects.
277
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000278- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000298- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
299 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000300 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000301 CXX from --with-cxx-main, see description in README.
302

313
Nick Coghlanda2268f2006-04-24 04:37:15 +0000314- test_contextlib now checks contextlib.nested can cope with exceptions
315 being raised and caught inside exit handlers.
316
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000317- test_cmd_line now checks operation of the -m and -c command switches
318
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000319- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
320 it separately and by hand. It also wasn't cleaning up its changes to
321 the current Decimal context.
322
Thomas Woutersabd08882006-04-26 15:53:30 +0000323- regrtest.py now has a -M option to run tests that test the new limits of
324 containers, on 64-bit architectures. Running these tests is only sensible
325 on 64-bit machines with more than two gigabytes of memory. The argument
326 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000334Documentation
335-------------
336
Tim Petersb06d28c2006-05-12 01:57:59 +0000337- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
338
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000339- PEP 343: Added Context Types section to the library reference
340 and attempted to bring other PEP 343 related documentation into
341 line with the implementation and/or python-dev discussions.
342
Tim Peters8dc73d22006-04-24 02:03:16 +0000343- Bug #1337990: clarified that ``doctest`` does not support examples
344 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000347What's New in Python 2.5 alpha 1?
348=================================
349
Anthony Baxterebed3f62006-04-03 15:03:44 +0000350*Release date: 05-APR-2006*

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000352Core and builtins
353-----------------
354
Nick Coghlan43832302006-04-23 17:04:07 +0000355- PEP 338: -m command line switch now delegates to runpy.run_module
356 allowing it to support modules in packages and zipfiles
357
Martin v. Löwisc661b882006-04-20 04:54:23 +0000358- On Windows, .DLL is not an accepted file name extension for
359 extension modules anymore; extensions are only found if they
360 end in .PYD.
361
Martin v. Löwisea62d252006-04-03 10:56:49 +0000362- Bug #1421664: sys.stderr.encoding is now set to the same value as
363 sys.stdout.encoding.
364
Neal Norwitz92e212f2006-04-03 04:48:37 +0000365- __import__ accepts keyword arguments.
366
Georg Brandlccadf842006-03-31 18:54:53 +0000367- Patch #1460496: round() now accepts keyword arguments.
368
Anthony Baxter262c00a2006-03-30 10:53:17 +0000369- Fixed bug #1459029 - unicode reprs were double-escaped.
370
Hye-Shik Changd478f342006-03-23 12:32:36 +0000371- Patch #1396919: The system scope threads are reenabled on FreeBSD
372 5.4 and later versions.
373
Neal Norwitze98ccf62006-03-23 05:39:47 +0000374- Bug #1115379: Compiling a Unicode string with an encoding declaration
375 now gives a SyntaxError.
376
Georg Brandlabd1ff82006-03-18 07:59:59 +0000377- Previously, Python code had no easy way to access the contents of a
378 cell object. Now, a ``cell_contents`` attribute has been added
379 (closes patch #1170323).
380
Tim Peterscf79aac2006-03-16 01:14:46 +0000381- Patch #1123430: Python's small-object allocator now returns an arena to
382 the system ``free()`` when all memory within an arena becomes unused
383 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
384 freed. Some applications will see a drop in virtual memory size now,
385 especially long-running applications that, from time to time, temporarily
386 use a large number of small objects. Note that when Python returns an
387 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000388 platform C library will in turn return that memory to the operating system.
389 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000390 appears to be effective at least on Microsoft C and gcc-based systems.
391 Thanks to Evan Jones for hard work and patience.
392
Georg Brandl533ff6f2006-03-08 18:09:27 +0000393- Patch #1434038: property() now uses the getter's docstring if there is
394 no "doc" argument given. This makes it possible to legitimately use
395 property() as a decorator to produce a read-only property.
396
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000397- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
398 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
399 of requiring an int or long in slicing and a few other contexts, enabling
400 other objects (e.g. Numeric Python's integers) to be used as slice indices.
401
Neal Norwitz995acdf2006-03-07 05:01:00 +0000402- Fixed various bugs reported by Coverity's Prevent tool.
403
Brett Cannonbf364092006-03-01 04:25:17 +0000404- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
405 new exception base class, BaseException, which has a new message attribute.
406 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
407 Raising a string exception now raises a DeprecationWarning.
408
Thomas Woutersfb609f42006-02-28 16:37:25 +0000409- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
410 explicitly relative, using 'from .module import name' to mean 'from the same
411 package as this module is in. Imports without dots still default to the
412 old relative-then-absolute, unless 'from __future__ import
413 absolute_import' is used.
414
Brett Cannona7446e32006-02-27 23:39:10 +0000415- Properly check if 'warnings' raises an exception (usually when a filter set
416 to "error" is triggered) when raising a warning for raising string
417 exceptions.
418
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000419- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000420 The name was removed from Include/code.h.
421
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000422- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000423
Guido van Rossum1968ad32006-02-25 22:38:04 +0000424- Patch 1433928:
425 - The copy module now "copies" function objects (as atomic objects).
426 - dict.__getitem__ now looks for a __missing__ hook before raising
427 KeyError.
428
Tim Peters84ef21c2006-02-28 20:39:06 +0000429- PEP 343: with statement implemented. Needs ``from __future__ import
430 with_statement``. Use of 'with' as a variable will generate a warning.
431 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000432 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000433 The following objects have __context__ methods:
434 - The built-in file type.
435 - The thread.LockType type.
436 - The following types defined by the threading module:
437 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
438 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000439
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000440- Fix the encodings package codec search function to only search
441 inside its own package. Fixes problem reported in patch #1433198.
442
443 Note: Codec packages should implement and register their own
444 codec search function. PEP 100 has the details.
445
Martin v. Löwis18e16552006-02-15 17:27:45 +0000446- PEP 353: Using ssize_t as the index type.
447
Neal Norwitzfc76d632006-01-10 06:03:13 +0000448- Patch #1400181, fix unicode string formatting to not use the locale.
449 This is how string objects work. u'%f' could use , instead of .
450 for the decimal point. Now both strings and unicode always use periods.
451
Neal Norwitz671b9e32006-01-09 07:07:12 +0000452- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
453 configure would break checking curses.h.
454
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000455- Bug #959576: The pwd module is now builtin. This allows Python to be
456 built on UNIX platforms without $HOME set.
457
Neal Norwitzc10978f2005-12-19 06:07:16 +0000458- Bug #1072182, fix some potential problems if characters are signed.
459
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000460- Bug #889500, fix line number on SyntaxWarning for global declarations.
461
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000462- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
463
Neal Norwitze7214a12005-12-18 05:03:17 +0000464- Support for converting hex strings to floats no longer works.
465 This was not portable. float('0x3') now raises a ValueError.
466
Barry Warsaw2a38a862005-12-18 01:27:35 +0000467- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000468 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000469 is now displayed in interactive prompt banner.
470
Georg Brandlfa166682005-12-17 21:45:17 +0000471- Implementation of PEP 341 - Unification of try/except and try/finally.
472 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000473 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000474
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000475- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
476 now encodes backslash correctly.
477
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000478- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
479
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000480- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000481 and long longs.
482
Neal Norwitz67715f02005-11-09 06:59:35 +0000483- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000484 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000485 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000486
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000487- Replaced most Unicode charmap codecs with new ones using the
488 new Unicode translate string feature in the builtin charmap
489 codec; the codecs were created from the mapping tables available
490 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
491 encodings now include a mapping for the Apple logo)
492
Tim Peterse3547fd2005-12-16 23:13:57 +0000493- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000494
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000495- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000496
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000497- A new AST parser implementation was completed. The abstract
498 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000499 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000500
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000501- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000502 The following code now raises a SyntaxError: foo(a = i for i in range(10))
503
Neal Norwitz708e51a2005-10-03 04:48:15 +0000504- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
505
Neal Norwitz11bd1192005-10-03 00:54:56 +0000506- SF Bug #887946: fix segfault when redirecting stdin from a directory.
507 Provide a warning when a directory is passed on the command line.
508
Neal Norwitz40d37812005-10-02 01:48:49 +0000509- Fix segfault with invalid coding.
510
511- SF bug #772896: unknown encoding results in MemoryError.
512
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000513- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000514 supported a __len__() method which evaluated to False when the iterator
515 was empty.
516
Guido van Rossum630db602005-09-20 18:49:54 +0000517- On 64-bit platforms, when __len__() returns a value that cannot be
518 represented as a C int, raise OverflowError.
519
Skip Montanarof8948ca2005-09-19 03:54:46 +0000520- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000521 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000522
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000523- SF bug #893549: parsing keyword arguments was broken with a few format
524 codes.
525
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000526- Changes donated by Elemental Security to make it work on AIX 5.3
527 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
528 bug #105470: test_pwd fails on 64bit system (Opteron).
529
Guido van Rossum539c6622005-09-14 17:49:54 +0000530- Changes donated by Elemental Security to make it work on HP-UX 11 on
531 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
532
Georg Brandl4550b8d2005-08-26 06:43:52 +0000533- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000534 (fixes bug #1119418).
535
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000536- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
537
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000538- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
539 exceptions that cause a function to exit.
540
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000541- The implementation of set() and frozenset() was revised to use its
542 own internal data structure. Memory consumption is reduced by 1/3
543 and there are modest speed-ups as well. The API is unchanged.
544
Tim Petersde7990b2005-07-17 23:45:23 +0000545- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
546
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000547- SF bug #1229429: PyObject_CallMethod failed to decrement some
548 reference counts in some error exit cases.
549
Tim Petersecc6e6a2005-07-10 22:30:55 +0000550- SF bug #1185883: Python's small-object memory allocator took over
551 a block managed by the platform C library whenever a realloc specified
552 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000553 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000554 portable way to copy data from the C-managed block into Python's
555 small-object space without risking a memory fault. Python's small-object
556 realloc now leaves such blocks under the control of the platform C
557 realloc.
558
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000559- SF bug #1232517: An overflow error was not detected properly when
560 attempting to convert a large float to an int in os.utime().
561
Raymond Hettinger3296e692005-06-29 23:29:56 +0000562- SF bug #1224347: hex longs now print with lowercase letters just
563 like their int counterparts.
564
Michael W. Hudson188d4362005-06-20 16:52:57 +0000565- SF bug #1163563: the original fix for bug #1010677 ("thread Module
566 Breaks PyGILState_Ensure()") broke badly in the case of multiple
567 interpreter states; back out that fix and do a better job (see
568 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
569 for a longer write-up of the problem).
570
Michael W. Hudsondf888462005-06-03 14:41:55 +0000571- SF patch #1180995: marshal now uses a binary format by default when
572 serializing floats.
573
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000574- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
575 the routines that promise to produce IEEE 754 binary representations
576 of floats now simply copy bytes around.
577
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000578- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
579 278.
580
Brett Cannonc3647ac2005-04-26 03:45:26 +0000581- patch #1109424: int, long, float, complex, and unicode now check for the
582 proper magic slot for type conversions when subclassed. Previously the
583 magic slot was ignored during conversion. Semantics now match the way
584 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000585 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000586 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000587 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000588
Barry Warsawc8d907c2005-04-19 23:43:40 +0000589- Descriptors defined in C with a PyGetSetDef structure, where the setter is
590 NULL, now raise an AttributeError when attempting to set or delete the
591 attribute. Previously a TypeError was raised, but this was inconsistent
592 with the equivalent pure-Python implementation.
593
Michael W. Hudson774479c2005-04-18 08:46:17 +0000594- It is now safe to call PyGILState_Release() before
595 PyEval_InitThreads() (note that if there is reason to believe there
596 are multiple threads around you still must call PyEval_InitThreads()
597 before using the Python API; this fix is for extension modules that
598 have no way of knowing if Python is multi-threaded yet).
599
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000600- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
601 disabled caused a crash.
602
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000603- Bug #1165306: instancemethod_new allowed the creation of a method
604 with im_class == im_self == NULL, which caused a crash when called.
605
Tim Petersecc6e6a2005-07-10 22:30:55 +0000606- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000607 fixes the crash seen in bug #1165761
608

Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000630 an ferror() call.
631
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000632- min() and max() now support key= arguments with the same meaning as in

Jeremy Hyltonab630502005-02-04 18:44:06 +0000643- The parser did not complain about future statements in illegal

650
Tim Petersf4e69282006-02-27 17:15:31 +0000651- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
652 current thread state when the auto-GIL-state machinery knows about
653 it (since the thread state is being deleted, continuing to remember it
654 can't help, but can hurt if another thread happens to get created with
655 the same thread id).

Georg Brandl828fdef2006-04-01 08:59:03 +0000862 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000863 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000864 module will not be built.
865
Tim Petersc17976e2006-04-01 00:26:53 +0000866- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
867 aren't officially supported here, and trying to use them will probably
868 raise an exception some day. But dicts have been allowed, and "mostly
869 worked", so support for them won't go away without warning.
870
Georg Brandl338ef7d2006-03-31 18:42:16 +0000871- Bug #1445068: getpass.getpass() can now be given an explicit stream

Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000890- email 4.0 package now integrated. This is largely the same as the email 3.0
891 package that was included in Python 2.3, except that PEP 8 module names are
892 now used (e.g. mail.message instead of email.Message). The MIME classes
893 have been moved to a subpackage (e.g. email.mime.text instead of
894 email.MIMEText). The old names are still supported for now. Several
895 deprecated Message methods have been removed and lots of bugs have been
896 fixed. More details can be found in the email package documentation.
897

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

906 a ValueError instead of a StopIteration now (like file and cString.String do).

986
987 "The consensus of researchers in this area (at least as
988 expressed at the NIST Hash Function Workshop 10/31/05),
989 is that SHA-256 is a good choice for the time being, but
990 that research should continue, and other alternatives may
991 arise from this research. The larger SHA's also seem OK."

1149
Raymond Hettingerbab41432005-02-05 01:31:19 +00001150- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1151
Guido van Rossumd0641422005-02-03 15:01:24 +00001152- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1153 disables recursive traversal through instance attributes, which can
1154 be exploited in various ways.
1155
Tim Peterse3547fd2005-12-16 23:13:57 +00001156- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001157 flags on the HTTP listening socket.
1158
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001159- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1160 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1161
Tim Peterse3547fd2005-12-16 23:13:57 +00001162- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001163 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1164
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001165- Bug #1110478: Revert os.environ.update to do putenv again.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001167- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1168
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001169- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1170
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001171- Enhancements to the csv module:
1172
1173 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001174 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001175 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001176 + Dialect parameter parsing has been re-implemented to improve error
1177 reporting.
1178 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1179 dictates.
1180 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001181 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001182 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001183 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1184 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001185 + reader now allows \r characters to be quoted (previously it only allowed
1186 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001187 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001188 + Dialect classes passed to the module are no longer instantiated by
1189 the module before being parsed (the former validation scheme required
1190 this, but the mechanism was unreliable).
1191 + The dialect registry now contains instances of the internal
1192 C-coded dialect type, rather than references to python objects.
1193 + the internal c-coded dialect type is now immutable.
1194 + register_dialect now accepts the same keyword dialect specifications
1195 as the reader and writer, allowing the user to register dialects
1196 without first creating a dialect class.
1197 + a configurable limit to the size of parsed fields has been added -
1198 previously, an unmatched quote character could result in the entire
1199 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001200 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001201 the parser field size limit (returning the former limit). The initial
1202 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001203 + A line_num attribute has been added to the reader object, which tracks
1204 the number of lines read from the source iterator. This is not
1205 the same as the number of records returned, as records can span
1206 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001207 + reader and writer objects were not being registered with the cyclic-GC.
1208 This has been fixed.
1209
Brett Cannone6539c42005-01-08 02:43:53 +00001210- _DummyThread objects in the threading module now delete self.__block that is
1211 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1212 lock primitives tend to be limited in number and thus should not be wasted on
1213 a _DummyThread object. Fixes bug #1089632.
1214
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001215- The imghdr module now detects Exif files.
1216
Raymond Hettinger6065d322004-12-20 23:51:53 +00001217- StringIO.truncate() now correctly adjusts the size attribute.
1218 (Bug #951915).
1219
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001220- locale.py now uses an updated locale alias table (built using
1221 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1222 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001223 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001224
Raymond Hettinger3557f422004-12-07 12:02:02 +00001225- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1226
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001227- the pickle module no longer accepts the deprecated None option in the
1228 args tuple returned by __reduce__().
1229
Brett Cannon84667c02004-12-07 03:25:18 +00001230- optparse now optionally imports gettext. This allows its use in setup.py.
1231
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001232- the pickle module no longer uses the deprecated bin parameter.
1233
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001234- the shelve module no longer uses the deprecated binary parameter.
1235
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001236- the pstats module no longer uses the deprecated ignore() method.
1237
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001238- the filecmp module no longer uses the deprecated use_statcache argument.
1239
Raymond Hettinger664347b2004-12-04 21:21:53 +00001240- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1241 extended or overridden by subclasses. Formerly, the subclassed method would
1242 be ignored by the rest of the module. (Bug #1078905).
1243
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001244- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001245 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001246
Walter Dörwald36733692004-12-22 12:50:50 +00001247- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1248 once when a size argument is given. This prevents a buffer overflow in the
1249 tokenizer with very long source lines.
1250
Barry Warsaw538561e2006-01-01 21:48:54 +00001251- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1252 immediately after creating the object, without any intervening
1253 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001254
Skip Montanaro05885812005-01-16 20:48:27 +00001255- The reconvert.quote function can now emit triple-quoted strings. The
1256 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001257
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001258- ``UserString.MutableString`` now supports negative indices in
1259 ``__setitem__`` and ``__delitem__``
1260
Greg Ward40407942005-03-05 02:53:17 +00001261- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1262 correctly.
1263
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001264- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1265 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1266 character even if the user has passed a size parameter to get a proper
1267 line ending. Remove the special handling of a "\r\n" that has been split
1268 between two lines.
1269
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001270- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1271 about illegal code points. The codec now supports PEP 293 style error
1272 handlers.
1273
Walter Dörwald78a78b02005-09-01 12:04:29 +00001274- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001275 from the input stream, so that the output is a byte string in the correct
1276 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001277
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001278- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1279 considering it exactly like a '*'.
1280
Walter Dörwald007f8df2005-10-09 19:42:27 +00001281- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1282 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001283
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001284- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1285
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001286- Patch #1413711: Certain patterns of differences were making difflib
1287 touch the recursion limit.
1288
Walter Dörwald58917a62006-03-31 15:26:22 +00001289- Bug #947906: An object oriented interface has been added to the calendar
1290 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001291 called as a script (e.g. via ``python -mcalendar``). Localized month and
1292 weekday names can be ouput (even if an exotic encoding is used) using
1293 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001294
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001295Build
1296-----
1297
Neal Norwitz602d3392006-03-31 08:21:40 +00001298- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1299 by using -mieee gcc option.
1300
Martin v. Löwis86d66262006-02-17 08:40:11 +00001301- Patch #1432345: Make python compile on DragonFly.
1302
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001303- Build support for Win64-AMD64 was added.
1304
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001305- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1306
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001307- Patch #881820: look for openpty and forkpty also in libbsd.
1308
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001309- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1310 The zlib module is now builtin on Windows.
1311
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001312- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1313
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001314- Bug #1189330: configure did not correctly determine the necessary
1315 value of LINKCC if python was built with GCC 4.0.
1316
Trent Mick8321b422005-07-26 02:29:21 +00001317- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1318 vulnerability in zlib 1.2.1 and 1.2.2.
1319
Brett Cannon08cd5982005-04-24 22:26:38 +00001320- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1321 flags that change binary compatibility. Changes were also made to
1322 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001323 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001324
Bob Ippolitoed233462005-03-29 13:47:59 +00001325- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1326 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1327 no longer exists). This configure patch makes things right.
1328
Martin v. Löwise2713be2005-03-08 15:03:08 +00001329- Bug #1158607: Build with --disable-unicode again.
1330
Brett Cannon46d96232005-02-16 00:07:19 +00001331- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1332 defined. Discovered as a result of not being able to build on OS X.
1333
Brett Cannon516592f2004-12-07 00:42:59 +00001334- setup.py now uses the directories specified in LDFLAGS using the -L option
1335 and in CPPFLAGS using the -I option for adding library and include
1336 directories, respectively, for compiling extension modules against. This has
1337 led to the core being compiled using the values in CPPFLAGS. It also removes
1338 the need for the special-casing of both DarwinPorts and Fink for darwin since
1339 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1340 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1341 Fink, ``-I/opt/local/include`` for DarwinPorts).
1342
Brett Cannon43802422005-02-10 20:48:03 +00001343- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1344 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1345 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1346 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001348C API
1349-----
1350
Tim Petersc9d78aa2006-03-26 23:27:58 +00001351- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1352 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1353 is obtained via the ``PyObject_`` family, it must be released via the
1354 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1355 always been officially true, but when Python's small-object allocator was
1356 introduced, an attempt was made to cater to a few extension modules
1357 discovered at the time that obtained memory via ``PyObject_New`` but
1358 released it via ``PyMem_DEL``. It's years later, and if such code still
1359 exists it will fail now (probably with segfaults, but calling wrong
1360 low-level memory management functions can yield many symptoms).
1361
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001362- Added a C API for set and frozenset objects.
1363
Raymond Hettinger66517482004-12-03 11:45:13 +00001364- Removed PyRange_New().
1365
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001366- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1367 mapping argument now. This string is used as a mapping table. Byte values
1368 greater than the length of the string and 0xFFFE are treated as undefined
1369 mappings.
