12Core and builtins
13-----------------
14
Neal Norwitz1004a532006-05-15 07:17:23 +000015- Patch #1488312, Fix memory alignment problem on SPARC in unicode
16
Neal Norwitz373f0a72006-05-15 07:04:36 +000017- Bug #1487966: Fix SystemError with conditional expression in assignment
18
Martin v. Löwis879768d2006-05-11 13:28:43 +000019- WindowsError now has two error code attributes: errno, which carries
20 the error values from errno.h, and winerror, which carries the error
21 values from winerror.h. Previous versions put the winerror.h values
22 (from GetLastError()) into the errno attribute.
23
Martin v. Löwis77736712006-05-04 05:51:03 +000024- Patch #1475845: Raise IndentationError for unexpected indent.
25
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000026- Patch #1479181: split open() and file() from being aliases for each other.

29-----------------
30
Georg Brandl378d5922006-05-17 14:26:50 +000031- Patch #1490224: time.altzone is now set correctly on Cygwin.
32
Georg Brandl8d3342b2006-05-16 07:38:27 +000033- Patch #1435422: zlib's compress and decompress objects now have a
34 copy() method.
35
Neal Norwitz7a5fc282006-05-15 06:48:14 +000036- On Win32, os.listdir now supports arbitrarily-long Unicode path names
37 (up to the system limit of 32K characters).
38
39- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
40 As a result, these functions now raise WindowsError instead of OSError.
41
42- Calling Tk_Init twice is refused if the first call failed as that
43 may deadlock.
44
45Library
46-------
47
Georg Brandlb89316f2006-05-17 15:51:16 +000048- Patch #1180296: Two new functions were added to the locale module:
49 format_string() to get the effect of "format % items" but locale-aware,
50 and currency() to format a monetary number with currency sign.
51
Georg Brandle3a25832006-05-17 14:56:04 +000052- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
53 and several features added, such as speed and geometry control.
54
Georg Brandl49c8f4c2006-05-15 19:30:35 +000055- Patch #1488881: add support for external file objects in bz2 compressed
56 tarfiles.
57
Neal Norwitz7a5fc282006-05-15 06:48:14 +000058- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
59 stdout arguments, making it possible to redirect input and output
60 for remote debugging.
61
62- Patch #1484695: Update the tarfile module to version 0.8. This fixes
63 a couple of issues, notably handling of long file names using the
64 GNU LONGNAME extension.
65
66- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
67 new flag when ``name`` is already the name of an option flag.
68
69- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
70 package.
71
72- Patch #1472854: make the rlcompleter.Completer class usable on non-
73 UNIX platforms.
74
75- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

95=================================
96
97*Release date: 27-APR-2006*
98
99Core and builtins
100-----------------
101
Thomas Heller1b046642006-04-18 18:51:06 +0000102- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
103 by converting these apis from macros into exported functions again:
104
105 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
106 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
107 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
108 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
109 PyRun_String Py_CompileString
110
Martin v. Löwis45294a92006-04-18 06:24:08 +0000111- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
112
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000113- All uses of PyStructSequence_InitType have been changed to initialize
114 the type objects only once, even if the interpreter is initialized
115 multiple times.
116
Neal Norwitz61546162006-04-14 05:20:28 +0000117- Bug #1454485, array.array('u') could crash the interpreter. This was
118 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
119 to unicode when it didn't make sense. 'u#' now requires a unicode string.
120
121- Py_UNICODE is unsigned. It was always documented as unsigned, but
122 due to a bug had a signed value in previous versions.
123
Tim Peters3a5e8b12006-04-11 01:44:07 +0000124- Patch #837242: ``id()`` of any Python object always gives a positive
125 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
126 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000127 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000128 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000129
Tim Peters3a5e8b12006-04-11 01:44:07 +0000130 def __hash__(self):
131 return id(self) # WRONG
132
133 because a hash result must be a (short) Python int but it was always
134 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000135 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000136 was always usable as a hash value before this patch. That's no longer
137 necessarily so.
138
139- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000140 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000141 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000142 #1454844)
143
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000144- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
145 involving generators that have paused outside of any ``try`` or ``with``
146 blocks. (In 2.5a1, a paused generator that was part of a reference
147 cycle could not be garbage collected, regardless of whether it was
148 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000150Extension Modules
151-----------------
152
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000153- Patch #1191065: Fix preprocessor problems on systems where recvfrom
154 is a macro.
155
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000156- Bug #1467952: os.listdir() now correctly raises an error if readdir()
157 fails with an error condition.
158
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000159- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
160
161- Bug #1117761: bsddb.*open() no longer raises an exception when using
162 the cachesize parameter.
163
164- Bug #1149413: bsddb.*open() no longer raises an exception when using
165 a temporary db (file=None) with the 'n' flag to truncate on open.
166
167- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
168 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000169
Armin Rigoa9017c32006-04-19 11:50:27 +0000170- Patch #1062014: AF_UNIX sockets under Linux have a special
171 abstract namespace that is now fully supported.
172
Anthony Baxter51bcb682006-04-05 14:51:42 +0000173Library
174-------
175
Tim Peters711bf302006-04-25 03:31:36 +0000176- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
177 a doctest to be skipped (the code is not run, and the expected output
178 or exception is ignored).
179
Nick Coghlanda2268f2006-04-24 04:37:15 +0000180- Fixed contextlib.nested to cope with exceptions being raised and
181 caught inside exit handlers.
182
Greg Wardab05edc2006-04-23 03:47:58 +0000183- Updated optparse module to Optik 1.5.1 (allow numeric constants in
184 hex, octal, or binary; add ``append_const`` action; keep going if
185 gettext cannot be imported; added ``OptionParser.destroy()`` method;
186 added ``epilog`` for better help generation).
187
Tim Peters21fbd572006-04-21 21:18:10 +0000188- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
189 called from a thread spawned as a side effect of importing a module.
190
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000191- The pydoc module now supports documenting packages contained in
192 .zip or .egg files.
193
194- The pkgutil module now has several new utility functions, such
195 as ``walk_packages()`` to support working with packages that are either
196 in the filesystem or zip files.
197
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000198- The mailbox module can now modify and delete messages from
199 mailboxes, in addition to simply reading them. Thanks to Gregory
200 K. Johnson for writing the code, and to the 2005 Google Summer of
201 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000202
Tim Petersc7605f22006-04-17 21:12:33 +0000203- The ``__del__`` method of class ``local`` in module ``_threading_local``
204 returned before accomplishing any of its intended cleanup.
205
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000206- Patch #790710: Add breakpoint command lists in pdb.
207
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000208- Patch #1063914: Add Tkinter.Misc.clipboard_get().
209
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000210- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
211
Anthony Baxtere29002c2006-04-12 12:07:31 +0000212- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
213 Windows. Bug #1469163.
214
Phillip J. Eby47032112006-04-11 01:07:43 +0000215- The warnings, linecache, inspect, traceback, site, and doctest modules
216 were updated to work correctly with modules imported from zipfiles or
217 via other PEP 302 __loader__ objects.
218
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000219- Patch #1467770: Reduce usage of subprocess._active to processes which
220 the application hasn't waited on.
221
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000222- Patch #1462222: Fix Tix.Grid.
223
Neal Norwitza31bf182006-04-09 03:35:43 +0000224- Fix exception when doing glob.glob('anything*/')
225
Skip Montanaro262fb922006-04-21 02:31:07 +0000226- The pstats.Stats class accepts an optional stream keyword argument to
227 direct output to an alternate file-like object.
228
Anthony Baxter51bcb682006-04-05 14:51:42 +0000229Build
230-----
231
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000232- The Makefile now has a reindent target, which runs reindent.py on
233 the library.
234
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000235- Patch #1470875: Building Python with MS Free Compiler
236
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000237- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000238
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000239- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
240 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000241 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000242 CXX from --with-cxx-main, see description in README.
243
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000244- Patch #1429775: Link extension modules with the shared libpython.
245
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000246- Fixed a libffi build problem on MIPS systems.
247
Tim Peters8931ff12006-05-13 23:28:20 +0000248- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
249 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
250 and "%zu" for unsigned integers of type ``size_t``.
251
Anthony Baxter51bcb682006-04-05 14:51:42 +0000252Tests
253-----
254
Nick Coghlanda2268f2006-04-24 04:37:15 +0000255- test_contextlib now checks contextlib.nested can cope with exceptions
256 being raised and caught inside exit handlers.
257
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000258- test_cmd_line now checks operation of the -m and -c command switches
259
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000260- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
261 it separately and by hand. It also wasn't cleaning up its changes to
262 the current Decimal context.
263
Thomas Woutersabd08882006-04-26 15:53:30 +0000264- regrtest.py now has a -M option to run tests that test the new limits of
265 containers, on 64-bit architectures. Running these tests is only sensible
266 on 64-bit machines with more than two gigabytes of memory. The argument
267 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +0000278- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
279
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000280- PEP 343: Added Context Types section to the library reference
281 and attempted to bring other PEP 343 related documentation into
282 line with the implementation and/or python-dev discussions.
283
Tim Peters8dc73d22006-04-24 02:03:16 +0000284- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000288What's New in Python 2.5 alpha 1?
289=================================
290
Anthony Baxterebed3f62006-04-03 15:03:44 +0000291*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000292
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000293Core and builtins
294-----------------
295
Nick Coghlan43832302006-04-23 17:04:07 +0000296- PEP 338: -m command line switch now delegates to runpy.run_module
297 allowing it to support modules in packages and zipfiles
298
Martin v. Löwisc661b882006-04-20 04:54:23 +0000299- On Windows, .DLL is not an accepted file name extension for
300 extension modules anymore; extensions are only found if they
301 end in .PYD.
302
Martin v. Löwisea62d252006-04-03 10:56:49 +0000303- Bug #1421664: sys.stderr.encoding is now set to the same value as
304 sys.stdout.encoding.
305
Neal Norwitz92e212f2006-04-03 04:48:37 +0000306- __import__ accepts keyword arguments.
307
Georg Brandlccadf842006-03-31 18:54:53 +0000308- Patch #1460496: round() now accepts keyword arguments.
309
Anthony Baxter262c00a2006-03-30 10:53:17 +0000310- Fixed bug #1459029 - unicode reprs were double-escaped.
311
Hye-Shik Changd478f342006-03-23 12:32:36 +0000312- Patch #1396919: The system scope threads are reenabled on FreeBSD
313 5.4 and later versions.
314
Neal Norwitze98ccf62006-03-23 05:39:47 +0000315- Bug #1115379: Compiling a Unicode string with an encoding declaration
316 now gives a SyntaxError.
317
Georg Brandlabd1ff82006-03-18 07:59:59 +0000318- Previously, Python code had no easy way to access the contents of a
319 cell object. Now, a ``cell_contents`` attribute has been added
320 (closes patch #1170323).
321
Tim Peterscf79aac2006-03-16 01:14:46 +0000322- Patch #1123430: Python's small-object allocator now returns an arena to
323 the system ``free()`` when all memory within an arena becomes unused
324 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
325 freed. Some applications will see a drop in virtual memory size now,
326 especially long-running applications that, from time to time, temporarily
327 use a large number of small objects. Note that when Python returns an
328 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000329 platform C library will in turn return that memory to the operating system.
330 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000331 appears to be effective at least on Microsoft C and gcc-based systems.
332 Thanks to Evan Jones for hard work and patience.
333
Georg Brandl533ff6f2006-03-08 18:09:27 +0000334- Patch #1434038: property() now uses the getter's docstring if there is
335 no "doc" argument given. This makes it possible to legitimately use
336 property() as a decorator to produce a read-only property.
337
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000338- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
339 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
340 of requiring an int or long in slicing and a few other contexts, enabling
341 other objects (e.g. Numeric Python's integers) to be used as slice indices.
342
Neal Norwitz995acdf2006-03-07 05:01:00 +0000343- Fixed various bugs reported by Coverity's Prevent tool.
344
Brett Cannonbf364092006-03-01 04:25:17 +0000345- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
346 new exception base class, BaseException, which has a new message attribute.
347 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
348 Raising a string exception now raises a DeprecationWarning.
349
Thomas Woutersfb609f42006-02-28 16:37:25 +0000350- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
351 explicitly relative, using 'from .module import name' to mean 'from the same
352 package as this module is in. Imports without dots still default to the
353 old relative-then-absolute, unless 'from __future__ import
354 absolute_import' is used.
355
Brett Cannona7446e32006-02-27 23:39:10 +0000356- Properly check if 'warnings' raises an exception (usually when a filter set
357 to "error" is triggered) when raising a warning for raising string
358 exceptions.
359
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000360- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000361 The name was removed from Include/code.h.
362
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000363- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000364
Guido van Rossum1968ad32006-02-25 22:38:04 +0000365- Patch 1433928:
366 - The copy module now "copies" function objects (as atomic objects).
367 - dict.__getitem__ now looks for a __missing__ hook before raising
368 KeyError.
369
Tim Peters84ef21c2006-02-28 20:39:06 +0000370- PEP 343: with statement implemented. Needs ``from __future__ import
371 with_statement``. Use of 'with' as a variable will generate a warning.
372 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000373 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000374 The following objects have __context__ methods:
375 - The built-in file type.
376 - The thread.LockType type.
377 - The following types defined by the threading module:
378 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
379 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000380
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000381- Fix the encodings package codec search function to only search
382 inside its own package. Fixes problem reported in patch #1433198.
383
384 Note: Codec packages should implement and register their own
385 codec search function. PEP 100 has the details.
386
Martin v. Löwis18e16552006-02-15 17:27:45 +0000387- PEP 353: Using ssize_t as the index type.
388
Neal Norwitzfc76d632006-01-10 06:03:13 +0000389- Patch #1400181, fix unicode string formatting to not use the locale.
390 This is how string objects work. u'%f' could use , instead of .
391 for the decimal point. Now both strings and unicode always use periods.
392
Neal Norwitz671b9e32006-01-09 07:07:12 +0000393- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
394 configure would break checking curses.h.
395
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000396- Bug #959576: The pwd module is now builtin. This allows Python to be
397 built on UNIX platforms without $HOME set.
398
Neal Norwitzc10978f2005-12-19 06:07:16 +0000399- Bug #1072182, fix some potential problems if characters are signed.
400
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000401- Bug #889500, fix line number on SyntaxWarning for global declarations.
402
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000403- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
404
Neal Norwitze7214a12005-12-18 05:03:17 +0000405- Support for converting hex strings to floats no longer works.
406 This was not portable. float('0x3') now raises a ValueError.
407
Barry Warsaw2a38a862005-12-18 01:27:35 +0000408- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000409 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000410 is now displayed in interactive prompt banner.
411
Georg Brandlfa166682005-12-17 21:45:17 +0000412- Implementation of PEP 341 - Unification of try/except and try/finally.
413 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000414 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000415
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000416- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
417 now encodes backslash correctly.
418
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000419- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
420
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000421- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000422 and long longs.
423
Neal Norwitz67715f02005-11-09 06:59:35 +0000424- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000425 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000426 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000427
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000428- Replaced most Unicode charmap codecs with new ones using the
429 new Unicode translate string feature in the builtin charmap
430 codec; the codecs were created from the mapping tables available
431 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
432 encodings now include a mapping for the Apple logo)
433
Tim Peterse3547fd2005-12-16 23:13:57 +0000434- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000435
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000436- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000437
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000438- A new AST parser implementation was completed. The abstract
439 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000440 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000441
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000442- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000443 The following code now raises a SyntaxError: foo(a = i for i in range(10))
444
Neal Norwitz708e51a2005-10-03 04:48:15 +0000445- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
446
Neal Norwitz11bd1192005-10-03 00:54:56 +0000447- SF Bug #887946: fix segfault when redirecting stdin from a directory.
448 Provide a warning when a directory is passed on the command line.
449
Neal Norwitz40d37812005-10-02 01:48:49 +0000450- Fix segfault with invalid coding.
451
452- SF bug #772896: unknown encoding results in MemoryError.
453
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000454- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000455 supported a __len__() method which evaluated to False when the iterator
456 was empty.
457
Guido van Rossum630db602005-09-20 18:49:54 +0000458- On 64-bit platforms, when __len__() returns a value that cannot be
459 represented as a C int, raise OverflowError.
460
Skip Montanarof8948ca2005-09-19 03:54:46 +0000461- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000462 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000463
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000464- SF bug #893549: parsing keyword arguments was broken with a few format
465 codes.
466
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000467- Changes donated by Elemental Security to make it work on AIX 5.3
468 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
469 bug #105470: test_pwd fails on 64bit system (Opteron).
470
Guido van Rossum539c6622005-09-14 17:49:54 +0000471- Changes donated by Elemental Security to make it work on HP-UX 11 on
472 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
473
Georg Brandl4550b8d2005-08-26 06:43:52 +0000474- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000475 (fixes bug #1119418).
476
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000477- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
478
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000479- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
480 exceptions that cause a function to exit.
481
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000482- The implementation of set() and frozenset() was revised to use its
483 own internal data structure. Memory consumption is reduced by 1/3
484 and there are modest speed-ups as well. The API is unchanged.
485
Tim Petersde7990b2005-07-17 23:45:23 +0000486- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
487
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000488- SF bug #1229429: PyObject_CallMethod failed to decrement some
489 reference counts in some error exit cases.
490
Tim Petersecc6e6a2005-07-10 22:30:55 +0000491- SF bug #1185883: Python's small-object memory allocator took over
492 a block managed by the platform C library whenever a realloc specified
493 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000494 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000495 portable way to copy data from the C-managed block into Python's
496 small-object space without risking a memory fault. Python's small-object
497 realloc now leaves such blocks under the control of the platform C
498 realloc.
499
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000500- SF bug #1232517: An overflow error was not detected properly when
501 attempting to convert a large float to an int in os.utime().
502
Raymond Hettinger3296e692005-06-29 23:29:56 +0000503- SF bug #1224347: hex longs now print with lowercase letters just
504 like their int counterparts.
505
Michael W. Hudson188d4362005-06-20 16:52:57 +0000506- SF bug #1163563: the original fix for bug #1010677 ("thread Module
507 Breaks PyGILState_Ensure()") broke badly in the case of multiple
508 interpreter states; back out that fix and do a better job (see
509 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
510 for a longer write-up of the problem).
511
Michael W. Hudsondf888462005-06-03 14:41:55 +0000512- SF patch #1180995: marshal now uses a binary format by default when
513 serializing floats.
514
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000515- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
516 the routines that promise to produce IEEE 754 binary representations
517 of floats now simply copy bytes around.
518
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000519- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
520 278.
521
Brett Cannonc3647ac2005-04-26 03:45:26 +0000522- patch #1109424: int, long, float, complex, and unicode now check for the
523 proper magic slot for type conversions when subclassed. Previously the
524 magic slot was ignored during conversion. Semantics now match the way
525 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000526 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000527 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000528 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000529
Barry Warsawc8d907c2005-04-19 23:43:40 +0000530- Descriptors defined in C with a PyGetSetDef structure, where the setter is
531 NULL, now raise an AttributeError when attempting to set or delete the
532 attribute. Previously a TypeError was raised, but this was inconsistent
533 with the equivalent pure-Python implementation.
534
Michael W. Hudson774479c2005-04-18 08:46:17 +0000535- It is now safe to call PyGILState_Release() before
536 PyEval_InitThreads() (note that if there is reason to believe there
537 are multiple threads around you still must call PyEval_InitThreads()
538 before using the Python API; this fix is for extension modules that
539 have no way of knowing if Python is multi-threaded yet).
540
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000541- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
542 disabled caused a crash.
543
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000544- Bug #1165306: instancemethod_new allowed the creation of a method
545 with im_class == im_self == NULL, which caused a crash when called.
546
Tim Petersecc6e6a2005-07-10 22:30:55 +0000547- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000548 fixes the crash seen in bug #1165761
549
Raymond Hettinger96229b12005-03-11 06:49:40 +0000550- Added two new builtins, any() and all().
551
Brett Cannon409d8f22005-03-05 06:47:57 +0000552- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000553 (e.g., ``class C(): pass`` is no longer a syntax error).
554 Patch #1176012 added support to the 'parser' module and 'compiler' package
555 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000556
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000557- Patch #1115086: Support PY_LONGLONG in structmember.
558
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000559- Bug #1155938: new style classes did not check that __init__() was
560 returning None.
561
Tim Petersecc6e6a2005-07-10 22:30:55 +0000562- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000563 ('\') with a specific error message.
564
Martin v. Löwisff232d72005-03-03 09:24:38 +0000565- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
566
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000567- Bug #1124295: the __name__ attribute of file objects was
568 inadvertently made inaccessible in restricted mode.
569
Tim Petersecc6e6a2005-07-10 22:30:55 +0000570- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000571 an ferror() call.
572
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000573- min() and max() now support key= arguments with the same meaning as in
574 list.sort().
575
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000576- The peephole optimizer now performs simple constant folding in expressions:
577 (2+3) --> (5).
578
Raymond Hettingera422c342005-01-11 03:03:27 +0000579- set and frozenset objects can now be marshalled. SF #1098985.
580
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000581- Bug #1077106: Poor argument checking could cause memory corruption
582 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000583
Jeremy Hyltonab630502005-02-04 18:44:06 +0000584- The parser did not complain about future statements in illegal
585 positions. It once again reports a syntax error if a future
586 statement occurs after anything other than a doc string.
587
Neil Schemenauercf52c072005-08-12 17:34:58 +0000588- Change the %s format specifier for str objects so that it returns a
589 unicode instance if the argument is not an instance of basestring and
590 calling __str__ on the argument returns a unicode instance.
591
Tim Petersf4e69282006-02-27 17:15:31 +0000592- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
593 current thread state when the auto-GIL-state machinery knows about
594 it (since the thread state is being deleted, continuing to remember it
595 can't help, but can hurt if another thread happens to get created with
596 the same thread id).
597
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000598Extension Modules
599-----------------
600
Georg Brandl43f08a82006-03-31 18:01:16 +0000601- Patch #1380952: fix SSL objects timing out on consecutive read()s
602
Neal Norwitz05a45592006-03-20 06:30:08 +0000603- Patch #1309579: wait3 and wait4 were added to the posix module.
604
Anthony Baxterfa869072006-03-20 05:21:58 +0000605- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
606 In addition, the existing ulaw code was updated.

786-------
787
Nick Coghlan43832302006-04-23 17:04:07 +0000788- PEP 338: new module runpy defines a run_module function to support
789 executing modules which provide access to source code or a code object
790 via the PEP 302 import mechanisms.

Georg Brandl828fdef2006-04-01 08:59:03 +0000803 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000804 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000805 module will not be built.
806
Tim Petersc17976e2006-04-01 00:26:53 +0000807- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
808 aren't officially supported here, and trying to use them will probably
809 raise an exception some day. But dicts have been allowed, and "mostly
810 worked", so support for them won't go away without warning.
811
Georg Brandl338ef7d2006-03-31 18:42:16 +0000812- Bug #1445068: getpass.getpass() can now be given an explicit stream

830
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000831- email 4.0 package now integrated. This is largely the same as the email 3.0
832 package that was included in Python 2.3, except that PEP 8 module names are
833 now used (e.g. mail.message instead of email.Message). The MIME classes
834 have been moved to a subpackage (e.g. email.mime.text instead of
835 email.MIMEText). The old names are still supported for now. Several
836 deprecated Message methods have been removed and lots of bugs have been
837 fixed. More details can be found in the email package documentation.
838
Walter Dörwald40108c92006-03-27 08:15:44 +0000839- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
840 (a subclass of tuple) that provides incremental decoders and encoders
841 (a way to use stateful codecs without the stream API). Python functions
842 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
843 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
844 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +0000846- Patch #1359365: Calling next() on a closed StringIO.String object raises
847 a ValueError instead of a StopIteration now (like file and cString.String do).
848 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
849 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000850

Tim Peterse3547fd2005-12-16 23:13:57 +0000923 SHA1, 224, 256, 384, and 512. Note that recent developments make the
924 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
925 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
926 Ronald L. Rivest offered this advice for Python:
927
928 "The consensus of researchers in this area (at least as
929 expressed at the NIST Hash Function Workshop 10/31/05),
930 is that SHA-256 is a good choice for the time being, but
931 that research should continue, and other alternatives may
932 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000933
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000934- Added a subset of Fredrik Lundh's ElementTree package. Available

1027 Bug #1224621.
1028
Raymond Hettinger68c04532005-06-10 11:05:19 +00001029- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001030 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001031 the generate_tokens() function now accepts a callable argument that
1032 terminates by raising StopIteration.
1033
Georg Brandl9166e1a2005-06-04 09:20:03 +00001034- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1052 allows other classes to implement __radd__ style methods and have them
1053 work as expected.
1054
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001055- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00001093- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1094 disables recursive traversal through instance attributes, which can
1095 be exploited in various ways.
1096
Tim Peterse3547fd2005-12-16 23:13:57 +00001097- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001098 flags on the HTTP listening socket.
1099

1111
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001112- Enhancements to the csv module:
1113
1114 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001115 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001116 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001117 + Dialect parameter parsing has been re-implemented to improve error
1118 reporting.
1119 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1120 dictates.
1121 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001122 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001123 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001124 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1125 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001126 + reader now allows \r characters to be quoted (previously it only allowed
1127 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001128 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001129 + Dialect classes passed to the module are no longer instantiated by
1130 the module before being parsed (the former validation scheme required
1131 this, but the mechanism was unreliable).
1132 + The dialect registry now contains instances of the internal
1133 C-coded dialect type, rather than references to python objects.
1134 + the internal c-coded dialect type is now immutable.
1135 + register_dialect now accepts the same keyword dialect specifications
1136 as the reader and writer, allowing the user to register dialects
1137 without first creating a dialect class.
1138 + a configurable limit to the size of parsed fields has been added -
1139 previously, an unmatched quote character could result in the entire
1140 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001141 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001142 the parser field size limit (returning the former limit). The initial
1143 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001144 + A line_num attribute has been added to the reader object, which tracks
1145 the number of lines read from the source iterator. This is not
1146 the same as the number of records returned, as records can span
1147 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001148 + reader and writer objects were not being registered with the cyclic-GC.
1149 This has been fixed.
1150
Brett Cannone6539c42005-01-08 02:43:53 +00001151- _DummyThread objects in the threading module now delete self.__block that is
1152 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1153 lock primitives tend to be limited in number and thus should not be wasted on
1154 a _DummyThread object. Fixes bug #1089632.
1155
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001156- The imghdr module now detects Exif files.
1157
Raymond Hettinger6065d322004-12-20 23:51:53 +00001158- StringIO.truncate() now correctly adjusts the size attribute.
1159 (Bug #951915).
1160
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001161- locale.py now uses an updated locale alias table (built using
1162 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1163 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001164 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001165
Raymond Hettinger3557f422004-12-07 12:02:02 +00001166- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1167
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001168- the pickle module no longer accepts the deprecated None option in the
1169 args tuple returned by __reduce__().
1170
Brett Cannon84667c02004-12-07 03:25:18 +00001171- optparse now optionally imports gettext. This allows its use in setup.py.
1172
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001173- the pickle module no longer uses the deprecated bin parameter.
1174
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001175- the shelve module no longer uses the deprecated binary parameter.
1176

1178
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001179- the filecmp module no longer uses the deprecated use_statcache argument.
1180
Raymond Hettinger664347b2004-12-04 21:21:53 +00001181- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1182 extended or overridden by subclasses. Formerly, the subclassed method would
1183 be ignored by the rest of the module. (Bug #1078905).
1184
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001185- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001186 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001187
Walter Dörwald36733692004-12-22 12:50:50 +00001188- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1189 once when a size argument is given. This prevents a buffer overflow in the
1190 tokenizer with very long source lines.
1191
Barry Warsaw538561e2006-01-01 21:48:54 +00001192- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1193 immediately after creating the object, without any intervening
1194 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001195
Skip Montanaro05885812005-01-16 20:48:27 +00001196- The reconvert.quote function can now emit triple-quoted strings. The
1197 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001198
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001199- ``UserString.MutableString`` now supports negative indices in
1200 ``__setitem__`` and ``__delitem__``
1201
Greg Ward40407942005-03-05 02:53:17 +00001202- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1203 correctly.
1204
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001205- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1206 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1207 character even if the user has passed a size parameter to get a proper
1208 line ending. Remove the special handling of a "\r\n" that has been split
1209 between two lines.
1210
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001211- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1212 about illegal code points. The codec now supports PEP 293 style error
1213 handlers.
1214
Walter Dörwald78a78b02005-09-01 12:04:29 +00001215- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001216 from the input stream, so that the output is a byte string in the correct
1217 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001218
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001219- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1220 considering it exactly like a '*'.
1221
Walter Dörwald007f8df2005-10-09 19:42:27 +00001222- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1223 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001224
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001225- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1226
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001227- Patch #1413711: Certain patterns of differences were making difflib
1228 touch the recursion limit.
1229
Walter Dörwald58917a62006-03-31 15:26:22 +00001230- Bug #947906: An object oriented interface has been added to the calendar
1231 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001232 called as a script (e.g. via ``python -mcalendar``). Localized month and
1233 weekday names can be ouput (even if an exotic encoding is used) using
1234 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001235
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001236Build
1237-----
1238
Neal Norwitz602d3392006-03-31 08:21:40 +00001239- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1240 by using -mieee gcc option.
1241
Martin v. Löwis86d66262006-02-17 08:40:11 +00001242- Patch #1432345: Make python compile on DragonFly.
1243
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001244- Build support for Win64-AMD64 was added.
1245
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001246- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1247
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001248- Patch #881820: look for openpty and forkpty also in libbsd.
1249
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001250- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1251 The zlib module is now builtin on Windows.
1252
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001253- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1254
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001255- Bug #1189330: configure did not correctly determine the necessary
1256 value of LINKCC if python was built with GCC 4.0.
1257
Trent Mick8321b422005-07-26 02:29:21 +00001258- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1259 vulnerability in zlib 1.2.1 and 1.2.2.
1260
Brett Cannon08cd5982005-04-24 22:26:38 +00001261- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1262 flags that change binary compatibility. Changes were also made to
1263 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001264 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001265
Bob Ippolitoed233462005-03-29 13:47:59 +00001266- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1267 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1268 no longer exists). This configure patch makes things right.
1269
Martin v. Löwise2713be2005-03-08 15:03:08 +00001270- Bug #1158607: Build with --disable-unicode again.
1271
Brett Cannon46d96232005-02-16 00:07:19 +00001272- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1273 defined. Discovered as a result of not being able to build on OS X.
1274
Brett Cannon516592f2004-12-07 00:42:59 +00001275- setup.py now uses the directories specified in LDFLAGS using the -L option
1276 and in CPPFLAGS using the -I option for adding library and include
1277 directories, respectively, for compiling extension modules against. This has
1278 led to the core being compiled using the values in CPPFLAGS. It also removes
1279 the need for the special-casing of both DarwinPorts and Fink for darwin since
1280 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1281 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1282 Fink, ``-I/opt/local/include`` for DarwinPorts).
1283
Brett Cannon43802422005-02-10 20:48:03 +00001284- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1285 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1286 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1287 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001289C API
1290-----
1291
Tim Petersc9d78aa2006-03-26 23:27:58 +00001292- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1293 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1294 is obtained via the ``PyObject_`` family, it must be released via the
1295 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1296 always been officially true, but when Python's small-object allocator was
1297 introduced, an attempt was made to cater to a few extension modules
1298 discovered at the time that obtained memory via ``PyObject_New`` but
1299 released it via ``PyMem_DEL``. It's years later, and if such code still
1300 exists it will fail now (probably with segfaults, but calling wrong
1301 low-level memory management functions can yield many symptoms).
1302
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001303- Added a C API for set and frozenset objects.
1304
Raymond Hettinger66517482004-12-03 11:45:13 +00001305- Removed PyRange_New().
1306
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001307- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1308 mapping argument now. This string is used as a mapping table. Byte values
1309 greater than the length of the string and 0xFFFE are treated as undefined
1310 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001317
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001318- Patch #1276356: New resource "urlfetch" is implemented. This enables
