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
George Yoshidaf3c65de2006-05-28 16:39:09 +000088- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
89
Bob Ippolito7298f272006-05-23 18:43:47 +000090- Patch #1281707: speed up gzip.readline.
91
Georg Brandlb89316f2006-05-17 15:51:16 +000092- Patch #1180296: Two new functions were added to the locale module:
93 format_string() to get the effect of "format % items" but locale-aware,
94 and currency() to format a monetary number with currency sign.
95
Georg Brandle3a25832006-05-17 14:56:04 +000096- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
97 and several features added, such as speed and geometry control.
98
Georg Brandl49c8f4c2006-05-15 19:30:35 +000099- Patch #1488881: add support for external file objects in bz2 compressed
100 tarfiles.
101
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000102- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
103 stdout arguments, making it possible to redirect input and output
104 for remote debugging.
105
106- Patch #1484695: Update the tarfile module to version 0.8. This fixes
107 a couple of issues, notably handling of long file names using the
108 GNU LONGNAME extension.
109
110- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
111 new flag when ``name`` is already the name of an option flag.
112
113- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
114 package.
115
116- Patch #1472854: make the rlcompleter.Completer class usable on non-
117 UNIX platforms.
118
119- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Martin v. Löwisa43190b2006-05-22 09:15:18 +0000124- Patch #1492356: Port to Windows CE.
125
Neal Norwitz58e28882006-05-19 07:00:58 +0000126- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.

142What's New in Python 2.5 alpha 2?
143=================================
144
145*Release date: 27-APR-2006*
146
147Core and builtins
148-----------------
149
Thomas Heller1b046642006-04-18 18:51:06 +0000150- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
151 by converting these apis from macros into exported functions again:
152
153 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
154 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
155 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
156 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
157 PyRun_String Py_CompileString
158
Martin v. Löwis45294a92006-04-18 06:24:08 +0000159- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
160
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000161- All uses of PyStructSequence_InitType have been changed to initialize
162 the type objects only once, even if the interpreter is initialized
163 multiple times.
164
Neal Norwitz61546162006-04-14 05:20:28 +0000165- Bug #1454485, array.array('u') could crash the interpreter. This was
166 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
167 to unicode when it didn't make sense. 'u#' now requires a unicode string.
168
169- Py_UNICODE is unsigned. It was always documented as unsigned, but
170 due to a bug had a signed value in previous versions.
171
Tim Peters3a5e8b12006-04-11 01:44:07 +0000172- Patch #837242: ``id()`` of any Python object always gives a positive
173 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
174 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000175 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000176 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000177
Tim Peters3a5e8b12006-04-11 01:44:07 +0000178 def __hash__(self):
179 return id(self) # WRONG
180
181 because a hash result must be a (short) Python int but it was always
182 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000183 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000184 was always usable as a hash value before this patch. That's no longer
185 necessarily so.
186
187- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000188 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000189 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000190 #1454844)
191
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000192- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
193 involving generators that have paused outside of any ``try`` or ``with``
194 blocks. (In 2.5a1, a paused generator that was part of a reference
195 cycle could not be garbage collected, regardless of whether it was
196 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +0000197
Anthony Baxter51bcb682006-04-05 14:51:42 +0000198Extension Modules
199-----------------
200
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000201- Patch #1191065: Fix preprocessor problems on systems where recvfrom
202 is a macro.
203
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000204- Bug #1467952: os.listdir() now correctly raises an error if readdir()
205 fails with an error condition.
206
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000207- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
208
209- Bug #1117761: bsddb.*open() no longer raises an exception when using
210 the cachesize parameter.
211
212- Bug #1149413: bsddb.*open() no longer raises an exception when using
213 a temporary db (file=None) with the 'n' flag to truncate on open.
214
215- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
216 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000217
Armin Rigoa9017c32006-04-19 11:50:27 +0000218- Patch #1062014: AF_UNIX sockets under Linux have a special
219 abstract namespace that is now fully supported.
220
Anthony Baxter51bcb682006-04-05 14:51:42 +0000221Library
222-------
223
Tim Peters711bf302006-04-25 03:31:36 +0000224- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
225 a doctest to be skipped (the code is not run, and the expected output
226 or exception is ignored).
227
Nick Coghlanda2268f2006-04-24 04:37:15 +0000228- Fixed contextlib.nested to cope with exceptions being raised and
229 caught inside exit handlers.
230
Greg Wardab05edc2006-04-23 03:47:58 +0000231- Updated optparse module to Optik 1.5.1 (allow numeric constants in
232 hex, octal, or binary; add ``append_const`` action; keep going if
233 gettext cannot be imported; added ``OptionParser.destroy()`` method;
234 added ``epilog`` for better help generation).
235
Tim Peters21fbd572006-04-21 21:18:10 +0000236- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
237 called from a thread spawned as a side effect of importing a module.
238
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000239- The pydoc module now supports documenting packages contained in
240 .zip or .egg files.
241
242- The pkgutil module now has several new utility functions, such
243 as ``walk_packages()`` to support working with packages that are either
244 in the filesystem or zip files.
245
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000246- The mailbox module can now modify and delete messages from
247 mailboxes, in addition to simply reading them. Thanks to Gregory
248 K. Johnson for writing the code, and to the 2005 Google Summer of
249 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000250
Tim Petersc7605f22006-04-17 21:12:33 +0000251- The ``__del__`` method of class ``local`` in module ``_threading_local``
252 returned before accomplishing any of its intended cleanup.
253
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000254- Patch #790710: Add breakpoint command lists in pdb.
255
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000256- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000258- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
259
Anthony Baxtere29002c2006-04-12 12:07:31 +0000260- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
261 Windows. Bug #1469163.
262
Phillip J. Eby47032112006-04-11 01:07:43 +0000263- The warnings, linecache, inspect, traceback, site, and doctest modules
264 were updated to work correctly with modules imported from zipfiles or
265 via other PEP 302 __loader__ objects.
266
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000267- Patch #1467770: Reduce usage of subprocess._active to processes which
268 the application hasn't waited on.
269

275 direct output to an alternate file-like object.
276

278-----
279
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000280- The Makefile now has a reindent target, which runs reindent.py on
281 the library.

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000287- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
288 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000289 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000290 CXX from --with-cxx-main, see description in README.
291

302
Nick Coghlanda2268f2006-04-24 04:37:15 +0000303- test_contextlib now checks contextlib.nested can cope with exceptions
304 being raised and caught inside exit handlers.
305
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000306- test_cmd_line now checks operation of the -m and -c command switches
307
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000308- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
309 it separately and by hand. It also wasn't cleaning up its changes to
310 the current Decimal context.
311
Thomas Woutersabd08882006-04-26 15:53:30 +0000312- regrtest.py now has a -M option to run tests that test the new limits of
313 containers, on 64-bit architectures. Running these tests is only sensible
314 on 64-bit machines with more than two gigabytes of memory. The argument
315 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000336What's New in Python 2.5 alpha 1?
337=================================
338
Anthony Baxterebed3f62006-04-03 15:03:44 +0000339*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000340
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000341Core and builtins
342-----------------
343
Nick Coghlan43832302006-04-23 17:04:07 +0000344- PEP 338: -m command line switch now delegates to runpy.run_module
345 allowing it to support modules in packages and zipfiles
346
Martin v. Löwisc661b882006-04-20 04:54:23 +0000347- On Windows, .DLL is not an accepted file name extension for
348 extension modules anymore; extensions are only found if they
349 end in .PYD.
350
Martin v. Löwisea62d252006-04-03 10:56:49 +0000351- Bug #1421664: sys.stderr.encoding is now set to the same value as
352 sys.stdout.encoding.
353
Neal Norwitz92e212f2006-04-03 04:48:37 +0000354- __import__ accepts keyword arguments.
355
Georg Brandlccadf842006-03-31 18:54:53 +0000356- Patch #1460496: round() now accepts keyword arguments.
357
Anthony Baxter262c00a2006-03-30 10:53:17 +0000358- Fixed bug #1459029 - unicode reprs were double-escaped.
359
Hye-Shik Changd478f342006-03-23 12:32:36 +0000360- Patch #1396919: The system scope threads are reenabled on FreeBSD
361 5.4 and later versions.
362
Neal Norwitze98ccf62006-03-23 05:39:47 +0000363- Bug #1115379: Compiling a Unicode string with an encoding declaration
364 now gives a SyntaxError.
365
Georg Brandlabd1ff82006-03-18 07:59:59 +0000366- Previously, Python code had no easy way to access the contents of a
367 cell object. Now, a ``cell_contents`` attribute has been added
368 (closes patch #1170323).
369
Tim Peterscf79aac2006-03-16 01:14:46 +0000370- Patch #1123430: Python's small-object allocator now returns an arena to
371 the system ``free()`` when all memory within an arena becomes unused
372 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
373 freed. Some applications will see a drop in virtual memory size now,
374 especially long-running applications that, from time to time, temporarily
375 use a large number of small objects. Note that when Python returns an
376 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000377 platform C library will in turn return that memory to the operating system.
378 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000379 appears to be effective at least on Microsoft C and gcc-based systems.
380 Thanks to Evan Jones for hard work and patience.
381
Georg Brandl533ff6f2006-03-08 18:09:27 +0000382- Patch #1434038: property() now uses the getter's docstring if there is
383 no "doc" argument given. This makes it possible to legitimately use
384 property() as a decorator to produce a read-only property.
385
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000386- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
387 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
388 of requiring an int or long in slicing and a few other contexts, enabling
389 other objects (e.g. Numeric Python's integers) to be used as slice indices.
390
Neal Norwitz995acdf2006-03-07 05:01:00 +0000391- Fixed various bugs reported by Coverity's Prevent tool.
392
Brett Cannonbf364092006-03-01 04:25:17 +0000393- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
394 new exception base class, BaseException, which has a new message attribute.
395 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
396 Raising a string exception now raises a DeprecationWarning.
397
Thomas Woutersfb609f42006-02-28 16:37:25 +0000398- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
399 explicitly relative, using 'from .module import name' to mean 'from the same
400 package as this module is in. Imports without dots still default to the
401 old relative-then-absolute, unless 'from __future__ import
402 absolute_import' is used.
403
Brett Cannona7446e32006-02-27 23:39:10 +0000404- Properly check if 'warnings' raises an exception (usually when a filter set
405 to "error" is triggered) when raising a warning for raising string
406 exceptions.
407
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000408- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000409 The name was removed from Include/code.h.
410
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000411- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000412
Guido van Rossum1968ad32006-02-25 22:38:04 +0000413- Patch 1433928:
414 - The copy module now "copies" function objects (as atomic objects).
415 - dict.__getitem__ now looks for a __missing__ hook before raising
416 KeyError.
417
Tim Peters84ef21c2006-02-28 20:39:06 +0000418- PEP 343: with statement implemented. Needs ``from __future__ import
419 with_statement``. Use of 'with' as a variable will generate a warning.
420 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000421 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000422 The following objects have __context__ methods:
423 - The built-in file type.
424 - The thread.LockType type.
425 - The following types defined by the threading module:
426 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
427 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000428
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000429- Fix the encodings package codec search function to only search
430 inside its own package. Fixes problem reported in patch #1433198.
431
432 Note: Codec packages should implement and register their own
433 codec search function. PEP 100 has the details.
434
Martin v. Löwis18e16552006-02-15 17:27:45 +0000435- PEP 353: Using ssize_t as the index type.
436
Neal Norwitzfc76d632006-01-10 06:03:13 +0000437- Patch #1400181, fix unicode string formatting to not use the locale.
438 This is how string objects work. u'%f' could use , instead of .
439 for the decimal point. Now both strings and unicode always use periods.
440
Neal Norwitz671b9e32006-01-09 07:07:12 +0000441- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
442 configure would break checking curses.h.
443
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000444- Bug #959576: The pwd module is now builtin. This allows Python to be
445 built on UNIX platforms without $HOME set.
446
Neal Norwitzc10978f2005-12-19 06:07:16 +0000447- Bug #1072182, fix some potential problems if characters are signed.
448
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000449- Bug #889500, fix line number on SyntaxWarning for global declarations.
450
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000451- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
452
Neal Norwitze7214a12005-12-18 05:03:17 +0000453- Support for converting hex strings to floats no longer works.
454 This was not portable. float('0x3') now raises a ValueError.
455
Barry Warsaw2a38a862005-12-18 01:27:35 +0000456- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000457 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000458 is now displayed in interactive prompt banner.
459
Georg Brandlfa166682005-12-17 21:45:17 +0000460- Implementation of PEP 341 - Unification of try/except and try/finally.
461 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000462 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000463
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000464- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
465 now encodes backslash correctly.
466
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000467- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
468
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000469- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000470 and long longs.
471
Neal Norwitz67715f02005-11-09 06:59:35 +0000472- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000473 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000474 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000475
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000476- Replaced most Unicode charmap codecs with new ones using the
477 new Unicode translate string feature in the builtin charmap
478 codec; the codecs were created from the mapping tables available
479 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
480 encodings now include a mapping for the Apple logo)
481
Tim Peterse3547fd2005-12-16 23:13:57 +0000482- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000483
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000484- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000485
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000486- A new AST parser implementation was completed. The abstract
487 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000488 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000489
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000490- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000491 The following code now raises a SyntaxError: foo(a = i for i in range(10))
492
Neal Norwitz708e51a2005-10-03 04:48:15 +0000493- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
494
Neal Norwitz11bd1192005-10-03 00:54:56 +0000495- SF Bug #887946: fix segfault when redirecting stdin from a directory.
496 Provide a warning when a directory is passed on the command line.
497
Neal Norwitz40d37812005-10-02 01:48:49 +0000498- Fix segfault with invalid coding.
499
500- SF bug #772896: unknown encoding results in MemoryError.
501
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000502- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000503 supported a __len__() method which evaluated to False when the iterator
504 was empty.
505
Guido van Rossum630db602005-09-20 18:49:54 +0000506- On 64-bit platforms, when __len__() returns a value that cannot be
507 represented as a C int, raise OverflowError.
508
Skip Montanarof8948ca2005-09-19 03:54:46 +0000509- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000510 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000511
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000512- SF bug #893549: parsing keyword arguments was broken with a few format
513 codes.
514
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000515- Changes donated by Elemental Security to make it work on AIX 5.3
516 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
517 bug #105470: test_pwd fails on 64bit system (Opteron).
518
Guido van Rossum539c6622005-09-14 17:49:54 +0000519- Changes donated by Elemental Security to make it work on HP-UX 11 on
520 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
521
Georg Brandl4550b8d2005-08-26 06:43:52 +0000522- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000523 (fixes bug #1119418).
524
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000525- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
526
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000527- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
528 exceptions that cause a function to exit.
529
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000530- The implementation of set() and frozenset() was revised to use its
531 own internal data structure. Memory consumption is reduced by 1/3
532 and there are modest speed-ups as well. The API is unchanged.
533
Tim Petersde7990b2005-07-17 23:45:23 +0000534- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
535
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000536- SF bug #1229429: PyObject_CallMethod failed to decrement some
537 reference counts in some error exit cases.
538
Tim Petersecc6e6a2005-07-10 22:30:55 +0000539- SF bug #1185883: Python's small-object memory allocator took over
540 a block managed by the platform C library whenever a realloc specified
541 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000542 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000543 portable way to copy data from the C-managed block into Python's
544 small-object space without risking a memory fault. Python's small-object
545 realloc now leaves such blocks under the control of the platform C
546 realloc.
547
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000548- SF bug #1232517: An overflow error was not detected properly when
549 attempting to convert a large float to an int in os.utime().
550
Raymond Hettinger3296e692005-06-29 23:29:56 +0000551- SF bug #1224347: hex longs now print with lowercase letters just
552 like their int counterparts.
553
Michael W. Hudson188d4362005-06-20 16:52:57 +0000554- SF bug #1163563: the original fix for bug #1010677 ("thread Module
555 Breaks PyGILState_Ensure()") broke badly in the case of multiple
556 interpreter states; back out that fix and do a better job (see
557 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
558 for a longer write-up of the problem).
559
Michael W. Hudsondf888462005-06-03 14:41:55 +0000560- SF patch #1180995: marshal now uses a binary format by default when
561 serializing floats.
562
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000563- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
564 the routines that promise to produce IEEE 754 binary representations
565 of floats now simply copy bytes around.
566
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000567- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
568 278.
569
Brett Cannonc3647ac2005-04-26 03:45:26 +0000570- patch #1109424: int, long, float, complex, and unicode now check for the
571 proper magic slot for type conversions when subclassed. Previously the
572 magic slot was ignored during conversion. Semantics now match the way
573 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000574 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000575 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000576 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000577
Barry Warsawc8d907c2005-04-19 23:43:40 +0000578- Descriptors defined in C with a PyGetSetDef structure, where the setter is
579 NULL, now raise an AttributeError when attempting to set or delete the
580 attribute. Previously a TypeError was raised, but this was inconsistent
581 with the equivalent pure-Python implementation.
582
Michael W. Hudson774479c2005-04-18 08:46:17 +0000583- It is now safe to call PyGILState_Release() before
584 PyEval_InitThreads() (note that if there is reason to believe there
585 are multiple threads around you still must call PyEval_InitThreads()
586 before using the Python API; this fix is for extension modules that
587 have no way of knowing if Python is multi-threaded yet).
588
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000589- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
590 disabled caused a crash.
591
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000592- Bug #1165306: instancemethod_new allowed the creation of a method
593 with im_class == im_self == NULL, which caused a crash when called.
594
Tim Petersecc6e6a2005-07-10 22:30:55 +0000595- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000596 fixes the crash seen in bug #1165761
597
Raymond Hettinger96229b12005-03-11 06:49:40 +0000598- Added two new builtins, any() and all().
599
Brett Cannon409d8f22005-03-05 06:47:57 +0000600- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000601 (e.g., ``class C(): pass`` is no longer a syntax error).
602 Patch #1176012 added support to the 'parser' module and 'compiler' package
603 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000604
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000605- Patch #1115086: Support PY_LONGLONG in structmember.
606
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000607- Bug #1155938: new style classes did not check that __init__() was

Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000619 an ferror() call.
620
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000621- min() and max() now support key= arguments with the same meaning as in

637 unicode instance if the argument is not an instance of basestring and
638 calling __str__ on the argument returns a unicode instance.
639
Tim Petersf4e69282006-02-27 17:15:31 +0000640- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
641 current thread state when the auto-GIL-state machinery knows about
642 it (since the thread state is being deleted, continuing to remember it
643 can't help, but can hurt if another thread happens to get created with
644 the same thread id).

832
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000833Library
834-------
835
Nick Coghlan43832302006-04-23 17:04:07 +0000836- PEP 338: new module runpy defines a run_module function to support
837 executing modules which provide access to source code or a code object
838 via the PEP 302 import mechanisms.
839

848 in attribute values.
849
Anthony Baxterc51ee692006-04-01 00:57:31 +0000850- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000851 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000852 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000853 module will not be built.
854
Tim Petersc17976e2006-04-01 00:26:53 +0000855- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
856 aren't officially supported here, and trying to use them will probably
857 raise an exception some day. But dicts have been allowed, and "mostly
858 worked", so support for them won't go away without warning.
859
Georg Brandl338ef7d2006-03-31 18:42:16 +0000860- Bug #1445068: getpass.getpass() can now be given an explicit stream
861 argument to specify where to write the prompt.
862
Georg Brandl22ec80b2006-03-31 18:25:44 +0000863- Patch #1462313, bug #1443328: the pickle modules now can handle classes

878
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000879- email 4.0 package now integrated. This is largely the same as the email 3.0
880 package that was included in Python 2.3, except that PEP 8 module names are
881 now used (e.g. mail.message instead of email.Message). The MIME classes
882 have been moved to a subpackage (e.g. email.mime.text instead of
883 email.MIMEText). The old names are still supported for now. Several
884 deprecated Message methods have been removed and lots of bugs have been

977 expressed at the NIST Hash Function Workshop 10/31/05),
978 is that SHA-256 is a good choice for the time being, but
979 that research should continue, and other alternatives may
980 arise from this research. The larger SHA's also seem OK."

Tim Peterse3547fd2005-12-16 23:13:57 +00001151- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001152 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1153
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001154- Bug #1110478: Revert os.environ.update to do putenv again.
1155
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001156- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1157
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001158- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1159
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001160- Enhancements to the csv module:
1161
1162 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001163 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001164 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001165 + Dialect parameter parsing has been re-implemented to improve error
1166 reporting.
1167 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1168 dictates.
1169 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001170 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001171 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001172 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1173 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001174 + reader now allows \r characters to be quoted (previously it only allowed
1175 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001176 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001177 + Dialect classes passed to the module are no longer instantiated by
1178 the module before being parsed (the former validation scheme required
1179 this, but the mechanism was unreliable).
1180 + The dialect registry now contains instances of the internal
1181 C-coded dialect type, rather than references to python objects.
1182 + the internal c-coded dialect type is now immutable.
1183 + register_dialect now accepts the same keyword dialect specifications
1184 as the reader and writer, allowing the user to register dialects
1185 without first creating a dialect class.
1186 + a configurable limit to the size of parsed fields has been added -
1187 previously, an unmatched quote character could result in the entire
1188 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001189 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001190 the parser field size limit (returning the former limit). The initial
1191 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001192 + A line_num attribute has been added to the reader object, which tracks
1193 the number of lines read from the source iterator. This is not
1194 the same as the number of records returned, as records can span
1195 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001196 + reader and writer objects were not being registered with the cyclic-GC.
1197 This has been fixed.
1198
Brett Cannone6539c42005-01-08 02:43:53 +00001199- _DummyThread objects in the threading module now delete self.__block that is
1200 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1201 lock primitives tend to be limited in number and thus should not be wasted on
1202 a _DummyThread object. Fixes bug #1089632.
1203
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001204- The imghdr module now detects Exif files.
1205
Raymond Hettinger6065d322004-12-20 23:51:53 +00001206- StringIO.truncate() now correctly adjusts the size attribute.
1207 (Bug #951915).
1208
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001209- locale.py now uses an updated locale alias table (built using
1210 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1211 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001212 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001213
Raymond Hettinger3557f422004-12-07 12:02:02 +00001214- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1215
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001216- the pickle module no longer accepts the deprecated None option in the
1217 args tuple returned by __reduce__().
1218
Brett Cannon84667c02004-12-07 03:25:18 +00001219- optparse now optionally imports gettext. This allows its use in setup.py.
1220
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001221- the pickle module no longer uses the deprecated bin parameter.
1222
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001223- the shelve module no longer uses the deprecated binary parameter.
1224
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001225- the pstats module no longer uses the deprecated ignore() method.
1226
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001227- the filecmp module no longer uses the deprecated use_statcache argument.
1228
Raymond Hettinger664347b2004-12-04 21:21:53 +00001229- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1230 extended or overridden by subclasses. Formerly, the subclassed method would
1231 be ignored by the rest of the module. (Bug #1078905).
1232
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001233- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001234 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001235
Walter Dörwald36733692004-12-22 12:50:50 +00001236- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1237 once when a size argument is given. This prevents a buffer overflow in the
1238 tokenizer with very long source lines.
1239
Barry Warsaw538561e2006-01-01 21:48:54 +00001240- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1241 immediately after creating the object, without any intervening
1242 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001243
Skip Montanaro05885812005-01-16 20:48:27 +00001244- The reconvert.quote function can now emit triple-quoted strings. The
1245 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001246
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001247- ``UserString.MutableString`` now supports negative indices in
1248 ``__setitem__`` and ``__delitem__``
1249
Greg Ward40407942005-03-05 02:53:17 +00001250- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1251 correctly.
1252
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001253- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1254 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1255 character even if the user has passed a size parameter to get a proper
1256 line ending. Remove the special handling of a "\r\n" that has been split
1257 between two lines.
1258
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001259- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1260 about illegal code points. The codec now supports PEP 293 style error
1261 handlers.
1262
Walter Dörwald78a78b02005-09-01 12:04:29 +00001263- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001264 from the input stream, so that the output is a byte string in the correct
1265 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001266
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001267- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1268 considering it exactly like a '*'.
1269
Walter Dörwald007f8df2005-10-09 19:42:27 +00001270- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1271 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001272
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001273- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1274
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001275- Patch #1413711: Certain patterns of differences were making difflib
1276 touch the recursion limit.
1277
Walter Dörwald58917a62006-03-31 15:26:22 +00001278- Bug #947906: An object oriented interface has been added to the calendar
1279 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001280 called as a script (e.g. via ``python -mcalendar``). Localized month and
1281 weekday names can be ouput (even if an exotic encoding is used) using
1282 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001283
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001284Build
1285-----
1286
Neal Norwitz602d3392006-03-31 08:21:40 +00001287- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1288 by using -mieee gcc option.
1289
Martin v. Löwis86d66262006-02-17 08:40:11 +00001290- Patch #1432345: Make python compile on DragonFly.
1291
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001292- Build support for Win64-AMD64 was added.
1293
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001294- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1295
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001296- Patch #881820: look for openpty and forkpty also in libbsd.
1297
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001298- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1299 The zlib module is now builtin on Windows.
1300
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001301- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1302
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001303- Bug #1189330: configure did not correctly determine the necessary
1304 value of LINKCC if python was built with GCC 4.0.
1305
Trent Mick8321b422005-07-26 02:29:21 +00001306- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1307 vulnerability in zlib 1.2.1 and 1.2.2.
1308
Brett Cannon08cd5982005-04-24 22:26:38 +00001309- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1310 flags that change binary compatibility. Changes were also made to
1311 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001312 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001313
Bob Ippolitoed233462005-03-29 13:47:59 +00001314- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1315 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1316 no longer exists). This configure patch makes things right.
1317
Martin v. Löwise2713be2005-03-08 15:03:08 +00001318- Bug #1158607: Build with --disable-unicode again.
1319
Brett Cannon46d96232005-02-16 00:07:19 +00001320- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1321 defined. Discovered as a result of not being able to build on OS X.
1322
Brett Cannon516592f2004-12-07 00:42:59 +00001323- setup.py now uses the directories specified in LDFLAGS using the -L option
1324 and in CPPFLAGS using the -I option for adding library and include
1325 directories, respectively, for compiling extension modules against. This has
1326 led to the core being compiled using the values in CPPFLAGS. It also removes
1327 the need for the special-casing of both DarwinPorts and Fink for darwin since
1328 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1329 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1330 Fink, ``-I/opt/local/include`` for DarwinPorts).
1331
Brett Cannon43802422005-02-10 20:48:03 +00001332- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1333 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1334 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1335 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001337C API
1338-----
1339
Tim Petersc9d78aa2006-03-26 23:27:58 +00001340- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1341 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1342 is obtained via the ``PyObject_`` family, it must be released via the
1343 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1344 always been officially true, but when Python's small-object allocator was
1345 introduced, an attempt was made to cater to a few extension modules
1346 discovered at the time that obtained memory via ``PyObject_New`` but
1347 released it via ``PyMem_DEL``. It's years later, and if such code still
1348 exists it will fail now (probably with segfaults, but calling wrong
1349 low-level memory management functions can yield many symptoms).
1350
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001351- Added a C API for set and frozenset objects.
1352
Raymond Hettinger66517482004-12-03 11:45:13 +00001353- Removed PyRange_New().
1354
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001355- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1356 mapping argument now. This string is used as a mapping table. Byte values
1357 greater than the length of the string and 0xFFFE are treated as undefined
1358 mappings.

1418 vimrc to it (was previous up a level).
1419
Georg Brandl56897312005-08-24 18:32:30 +00001420- Added two new files to Tools/scripts: pysource.py, which recursively
