12Core and builtins
13-----------------
14
Martin v. Löwis879768d2006-05-11 13:28:43 +000015- WindowsError now has two error code attributes: errno, which carries
16 the error values from errno.h, and winerror, which carries the error
17 values from winerror.h. Previous versions put the winerror.h values
18 (from GetLastError()) into the errno attribute.
19
Martin v. Löwis77736712006-05-04 05:51:03 +000020- Patch #1475845: Raise IndentationError for unexpected indent.
21
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000022- Patch #1479181: split open() and file() from being aliases for each other.
23
Neal Norwitz7a5fc282006-05-15 06:48:14 +000024Extension Modules
25-----------------
26
27- On Win32, os.listdir now supports arbitrarily-long Unicode path names
28 (up to the system limit of 32K characters).
29
30- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
31 As a result, these functions now raise WindowsError instead of OSError.
32
33- Calling Tk_Init twice is refused if the first call failed as that
34 may deadlock.
35
36Library
37-------
38
39- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
40 stdout arguments, making it possible to redirect input and output
41 for remote debugging.
42
43- Patch #1484695: Update the tarfile module to version 0.8. This fixes
44 a couple of issues, notably handling of long file names using the
45 GNU LONGNAME extension.
46
47- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
48 new flag when ``name`` is already the name of an option flag.
49
50- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
51 package.
52
53- Patch #1472854: make the rlcompleter.Completer class usable on non-
54 UNIX platforms.
55
56- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

75What's New in Python 2.5 alpha 2?
76=================================
77
78*Release date: 27-APR-2006*
79
80Core and builtins
81-----------------
82
Thomas Heller1b046642006-04-18 18:51:06 +000083- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
84 by converting these apis from macros into exported functions again:
85
86 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
87 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
88 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
89 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
90 PyRun_String Py_CompileString
91
Martin v. Löwis45294a92006-04-18 06:24:08 +000092- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
93
Martin v. Löwis19ab6c92006-04-16 18:55:50 +000094- All uses of PyStructSequence_InitType have been changed to initialize
95 the type objects only once, even if the interpreter is initialized
96 multiple times.
97
Neal Norwitz61546162006-04-14 05:20:28 +000098- Bug #1454485, array.array('u') could crash the interpreter. This was
99 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
100 to unicode when it didn't make sense. 'u#' now requires a unicode string.
101
102- Py_UNICODE is unsigned. It was always documented as unsigned, but
103 due to a bug had a signed value in previous versions.
104
Tim Peters3a5e8b12006-04-11 01:44:07 +0000105- Patch #837242: ``id()`` of any Python object always gives a positive
106 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
107 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000108 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000109 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000110
Tim Peters3a5e8b12006-04-11 01:44:07 +0000111 def __hash__(self):
112 return id(self) # WRONG
113
114 because a hash result must be a (short) Python int but it was always
115 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000116 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000117 was always usable as a hash value before this patch. That's no longer
118 necessarily so.
119
120- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000121 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000122 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000123 #1454844)
124
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000125- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
126 involving generators that have paused outside of any ``try`` or ``with``
127 blocks. (In 2.5a1, a paused generator that was part of a reference
128 cycle could not be garbage collected, regardless of whether it was
129 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000131Extension Modules
132-----------------
133
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000134- Patch #1191065: Fix preprocessor problems on systems where recvfrom
135 is a macro.
136
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000137- Bug #1467952: os.listdir() now correctly raises an error if readdir()
138 fails with an error condition.
139
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000140- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
141
142- Bug #1117761: bsddb.*open() no longer raises an exception when using
143 the cachesize parameter.
144
145- Bug #1149413: bsddb.*open() no longer raises an exception when using
146 a temporary db (file=None) with the 'n' flag to truncate on open.
147
148- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
149 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000150
Armin Rigoa9017c32006-04-19 11:50:27 +0000151- Patch #1062014: AF_UNIX sockets under Linux have a special
152 abstract namespace that is now fully supported.
153
Anthony Baxter51bcb682006-04-05 14:51:42 +0000154Library
155-------
156
Tim Peters711bf302006-04-25 03:31:36 +0000157- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
158 a doctest to be skipped (the code is not run, and the expected output
159 or exception is ignored).
160
Nick Coghlanda2268f2006-04-24 04:37:15 +0000161- Fixed contextlib.nested to cope with exceptions being raised and
162 caught inside exit handlers.
163
Greg Wardab05edc2006-04-23 03:47:58 +0000164- Updated optparse module to Optik 1.5.1 (allow numeric constants in
165 hex, octal, or binary; add ``append_const`` action; keep going if
166 gettext cannot be imported; added ``OptionParser.destroy()`` method;
167 added ``epilog`` for better help generation).
168
Tim Peters21fbd572006-04-21 21:18:10 +0000169- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
170 called from a thread spawned as a side effect of importing a module.
171
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000172- The pydoc module now supports documenting packages contained in
173 .zip or .egg files.
174
175- The pkgutil module now has several new utility functions, such
176 as ``walk_packages()`` to support working with packages that are either
177 in the filesystem or zip files.
178
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000179- The mailbox module can now modify and delete messages from
180 mailboxes, in addition to simply reading them. Thanks to Gregory
181 K. Johnson for writing the code, and to the 2005 Google Summer of
182 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000183
Tim Petersc7605f22006-04-17 21:12:33 +0000184- The ``__del__`` method of class ``local`` in module ``_threading_local``
185 returned before accomplishing any of its intended cleanup.
186
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000187- Patch #790710: Add breakpoint command lists in pdb.
188
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000189- Patch #1063914: Add Tkinter.Misc.clipboard_get().
190
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000191- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
192
Anthony Baxtere29002c2006-04-12 12:07:31 +0000193- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
194 Windows. Bug #1469163.
195
Phillip J. Eby47032112006-04-11 01:07:43 +0000196- The warnings, linecache, inspect, traceback, site, and doctest modules
197 were updated to work correctly with modules imported from zipfiles or
198 via other PEP 302 __loader__ objects.
199
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000200- Patch #1467770: Reduce usage of subprocess._active to processes which
201 the application hasn't waited on.
202
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000203- Patch #1462222: Fix Tix.Grid.
204
Neal Norwitza31bf182006-04-09 03:35:43 +0000205- Fix exception when doing glob.glob('anything*/')
206
Skip Montanaro262fb922006-04-21 02:31:07 +0000207- The pstats.Stats class accepts an optional stream keyword argument to
208 direct output to an alternate file-like object.
209
Anthony Baxter51bcb682006-04-05 14:51:42 +0000210Build

212
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000213- The Makefile now has a reindent target, which runs reindent.py on
214 the library.
215
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000216- Patch #1470875: Building Python with MS Free Compiler
217
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000218- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000219
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000220- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
221 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000222 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000223 CXX from --with-cxx-main, see description in README.
224
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000225- Patch #1429775: Link extension modules with the shared libpython.
226
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000227- Fixed a libffi build problem on MIPS systems.
228
Tim Peters8931ff12006-05-13 23:28:20 +0000229- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
230 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
231 and "%zu" for unsigned integers of type ``size_t``.

234-----
235
Nick Coghlanda2268f2006-04-24 04:37:15 +0000236- test_contextlib now checks contextlib.nested can cope with exceptions
237 being raised and caught inside exit handlers.
238
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000239- test_cmd_line now checks operation of the -m and -c command switches
240
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000241- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
242 it separately and by hand. It also wasn't cleaning up its changes to
243 the current Decimal context.
244
Thomas Woutersabd08882006-04-26 15:53:30 +0000245- regrtest.py now has a -M option to run tests that test the new limits of
246 containers, on 64-bit architectures. Running these tests is only sensible
247 on 64-bit machines with more than two gigabytes of memory. The argument
248 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +0000259- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
260
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000261- PEP 343: Added Context Types section to the library reference
262 and attempted to bring other PEP 343 related documentation into
263 line with the implementation and/or python-dev discussions.
264
Tim Peters8dc73d22006-04-24 02:03:16 +0000265- Bug #1337990: clarified that ``doctest`` does not support examples
266 requiring both expected output and an exception.

Anthony Baxterebed3f62006-04-03 15:03:44 +0000272*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000273
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000274Core and builtins
275-----------------
276
Nick Coghlan43832302006-04-23 17:04:07 +0000277- PEP 338: -m command line switch now delegates to runpy.run_module
278 allowing it to support modules in packages and zipfiles
279
Martin v. Löwisc661b882006-04-20 04:54:23 +0000280- On Windows, .DLL is not an accepted file name extension for
281 extension modules anymore; extensions are only found if they
282 end in .PYD.
283
Martin v. Löwisea62d252006-04-03 10:56:49 +0000284- Bug #1421664: sys.stderr.encoding is now set to the same value as
285 sys.stdout.encoding.
286
Neal Norwitz92e212f2006-04-03 04:48:37 +0000287- __import__ accepts keyword arguments.
288
Georg Brandlccadf842006-03-31 18:54:53 +0000289- Patch #1460496: round() now accepts keyword arguments.
290
Anthony Baxter262c00a2006-03-30 10:53:17 +0000291- Fixed bug #1459029 - unicode reprs were double-escaped.
292
Hye-Shik Changd478f342006-03-23 12:32:36 +0000293- Patch #1396919: The system scope threads are reenabled on FreeBSD
294 5.4 and later versions.
295
Neal Norwitze98ccf62006-03-23 05:39:47 +0000296- Bug #1115379: Compiling a Unicode string with an encoding declaration
297 now gives a SyntaxError.
298
Georg Brandlabd1ff82006-03-18 07:59:59 +0000299- Previously, Python code had no easy way to access the contents of a
300 cell object. Now, a ``cell_contents`` attribute has been added
301 (closes patch #1170323).
302
Tim Peterscf79aac2006-03-16 01:14:46 +0000303- Patch #1123430: Python's small-object allocator now returns an arena to
304 the system ``free()`` when all memory within an arena becomes unused
305 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
306 freed. Some applications will see a drop in virtual memory size now,
307 especially long-running applications that, from time to time, temporarily
308 use a large number of small objects. Note that when Python returns an
309 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000310 platform C library will in turn return that memory to the operating system.
311 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000312 appears to be effective at least on Microsoft C and gcc-based systems.
313 Thanks to Evan Jones for hard work and patience.
314
Georg Brandl533ff6f2006-03-08 18:09:27 +0000315- Patch #1434038: property() now uses the getter's docstring if there is
316 no "doc" argument given. This makes it possible to legitimately use
317 property() as a decorator to produce a read-only property.
318
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000319- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
320 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
321 of requiring an int or long in slicing and a few other contexts, enabling
322 other objects (e.g. Numeric Python's integers) to be used as slice indices.
323
Neal Norwitz995acdf2006-03-07 05:01:00 +0000324- Fixed various bugs reported by Coverity's Prevent tool.
325
Brett Cannonbf364092006-03-01 04:25:17 +0000326- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
327 new exception base class, BaseException, which has a new message attribute.
328 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
329 Raising a string exception now raises a DeprecationWarning.
330
Thomas Woutersfb609f42006-02-28 16:37:25 +0000331- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
332 explicitly relative, using 'from .module import name' to mean 'from the same
333 package as this module is in. Imports without dots still default to the
334 old relative-then-absolute, unless 'from __future__ import
335 absolute_import' is used.
336
Brett Cannona7446e32006-02-27 23:39:10 +0000337- Properly check if 'warnings' raises an exception (usually when a filter set
338 to "error" is triggered) when raising a warning for raising string
339 exceptions.
340
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000341- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000342 The name was removed from Include/code.h.
343
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000344- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000345
Guido van Rossum1968ad32006-02-25 22:38:04 +0000346- Patch 1433928:
347 - The copy module now "copies" function objects (as atomic objects).
348 - dict.__getitem__ now looks for a __missing__ hook before raising
349 KeyError.
350
Tim Peters84ef21c2006-02-28 20:39:06 +0000351- PEP 343: with statement implemented. Needs ``from __future__ import
352 with_statement``. Use of 'with' as a variable will generate a warning.
353 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000354 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000355 The following objects have __context__ methods:
356 - The built-in file type.
357 - The thread.LockType type.
358 - The following types defined by the threading module:
359 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
360 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000361
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000362- Fix the encodings package codec search function to only search
363 inside its own package. Fixes problem reported in patch #1433198.
364
365 Note: Codec packages should implement and register their own
366 codec search function. PEP 100 has the details.
367
Martin v. Löwis18e16552006-02-15 17:27:45 +0000368- PEP 353: Using ssize_t as the index type.
369
Neal Norwitzfc76d632006-01-10 06:03:13 +0000370- Patch #1400181, fix unicode string formatting to not use the locale.
371 This is how string objects work. u'%f' could use , instead of .
372 for the decimal point. Now both strings and unicode always use periods.
373
Neal Norwitz671b9e32006-01-09 07:07:12 +0000374- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
375 configure would break checking curses.h.
376
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000377- Bug #959576: The pwd module is now builtin. This allows Python to be
378 built on UNIX platforms without $HOME set.
379
Neal Norwitzc10978f2005-12-19 06:07:16 +0000380- Bug #1072182, fix some potential problems if characters are signed.
381
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000382- Bug #889500, fix line number on SyntaxWarning for global declarations.
383
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000384- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
385
Neal Norwitze7214a12005-12-18 05:03:17 +0000386- Support for converting hex strings to floats no longer works.
387 This was not portable. float('0x3') now raises a ValueError.
388
Barry Warsaw2a38a862005-12-18 01:27:35 +0000389- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000390 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000391 is now displayed in interactive prompt banner.
392
Georg Brandlfa166682005-12-17 21:45:17 +0000393- Implementation of PEP 341 - Unification of try/except and try/finally.
394 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000395 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000396
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000397- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
398 now encodes backslash correctly.
399
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000400- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
401
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000402- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000403 and long longs.
404
Neal Norwitz67715f02005-11-09 06:59:35 +0000405- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000406 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000407 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000408
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000409- Replaced most Unicode charmap codecs with new ones using the
410 new Unicode translate string feature in the builtin charmap
411 codec; the codecs were created from the mapping tables available
412 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
413 encodings now include a mapping for the Apple logo)
414
Tim Peterse3547fd2005-12-16 23:13:57 +0000415- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000416
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000417- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000418
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000419- A new AST parser implementation was completed. The abstract
420 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000421 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000422
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000423- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000424 The following code now raises a SyntaxError: foo(a = i for i in range(10))
425
Neal Norwitz708e51a2005-10-03 04:48:15 +0000426- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
427
Neal Norwitz11bd1192005-10-03 00:54:56 +0000428- SF Bug #887946: fix segfault when redirecting stdin from a directory.
429 Provide a warning when a directory is passed on the command line.
430
Neal Norwitz40d37812005-10-02 01:48:49 +0000431- Fix segfault with invalid coding.
432
433- SF bug #772896: unknown encoding results in MemoryError.
434
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000435- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000436 supported a __len__() method which evaluated to False when the iterator
437 was empty.
438
Guido van Rossum630db602005-09-20 18:49:54 +0000439- On 64-bit platforms, when __len__() returns a value that cannot be
440 represented as a C int, raise OverflowError.
441
Skip Montanarof8948ca2005-09-19 03:54:46 +0000442- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000443 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000444
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000445- SF bug #893549: parsing keyword arguments was broken with a few format
446 codes.
447
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000448- Changes donated by Elemental Security to make it work on AIX 5.3
449 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
450 bug #105470: test_pwd fails on 64bit system (Opteron).
451
Guido van Rossum539c6622005-09-14 17:49:54 +0000452- Changes donated by Elemental Security to make it work on HP-UX 11 on
453 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
454
Georg Brandl4550b8d2005-08-26 06:43:52 +0000455- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000456 (fixes bug #1119418).
457
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000458- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
459
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000460- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
461 exceptions that cause a function to exit.
462
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000463- The implementation of set() and frozenset() was revised to use its
464 own internal data structure. Memory consumption is reduced by 1/3
465 and there are modest speed-ups as well. The API is unchanged.
466
Tim Petersde7990b2005-07-17 23:45:23 +0000467- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
468
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000469- SF bug #1229429: PyObject_CallMethod failed to decrement some
470 reference counts in some error exit cases.
471
Tim Petersecc6e6a2005-07-10 22:30:55 +0000472- SF bug #1185883: Python's small-object memory allocator took over
473 a block managed by the platform C library whenever a realloc specified
474 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000475 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000476 portable way to copy data from the C-managed block into Python's
477 small-object space without risking a memory fault. Python's small-object
478 realloc now leaves such blocks under the control of the platform C
479 realloc.
480
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000481- SF bug #1232517: An overflow error was not detected properly when
482 attempting to convert a large float to an int in os.utime().
483
Raymond Hettinger3296e692005-06-29 23:29:56 +0000484- SF bug #1224347: hex longs now print with lowercase letters just
485 like their int counterparts.
486
Michael W. Hudson188d4362005-06-20 16:52:57 +0000487- SF bug #1163563: the original fix for bug #1010677 ("thread Module
488 Breaks PyGILState_Ensure()") broke badly in the case of multiple
489 interpreter states; back out that fix and do a better job (see
490 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
491 for a longer write-up of the problem).
492
Michael W. Hudsondf888462005-06-03 14:41:55 +0000493- SF patch #1180995: marshal now uses a binary format by default when
494 serializing floats.
495
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000496- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
497 the routines that promise to produce IEEE 754 binary representations
498 of floats now simply copy bytes around.
499
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000500- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
501 278.
502
Brett Cannonc3647ac2005-04-26 03:45:26 +0000503- patch #1109424: int, long, float, complex, and unicode now check for the
504 proper magic slot for type conversions when subclassed. Previously the
505 magic slot was ignored during conversion. Semantics now match the way
506 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000507 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000508 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000509 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000510
Barry Warsawc8d907c2005-04-19 23:43:40 +0000511- Descriptors defined in C with a PyGetSetDef structure, where the setter is
512 NULL, now raise an AttributeError when attempting to set or delete the
513 attribute. Previously a TypeError was raised, but this was inconsistent
514 with the equivalent pure-Python implementation.
515
Michael W. Hudson774479c2005-04-18 08:46:17 +0000516- It is now safe to call PyGILState_Release() before
517 PyEval_InitThreads() (note that if there is reason to believe there
518 are multiple threads around you still must call PyEval_InitThreads()
519 before using the Python API; this fix is for extension modules that
520 have no way of knowing if Python is multi-threaded yet).
521
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000522- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
523 disabled caused a crash.
524
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000525- Bug #1165306: instancemethod_new allowed the creation of a method
526 with im_class == im_self == NULL, which caused a crash when called.
527
Tim Petersecc6e6a2005-07-10 22:30:55 +0000528- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000529 fixes the crash seen in bug #1165761
530
Raymond Hettinger96229b12005-03-11 06:49:40 +0000531- Added two new builtins, any() and all().
532
Brett Cannon409d8f22005-03-05 06:47:57 +0000533- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000534 (e.g., ``class C(): pass`` is no longer a syntax error).
535 Patch #1176012 added support to the 'parser' module and 'compiler' package
536 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000537
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000538- Patch #1115086: Support PY_LONGLONG in structmember.
539
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000540- Bug #1155938: new style classes did not check that __init__() was
541 returning None.
542
Tim Petersecc6e6a2005-07-10 22:30:55 +0000543- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000544 ('\') with a specific error message.
545
Martin v. Löwisff232d72005-03-03 09:24:38 +0000546- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
547
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000548- Bug #1124295: the __name__ attribute of file objects was
549 inadvertently made inaccessible in restricted mode.
550
Tim Petersecc6e6a2005-07-10 22:30:55 +0000551- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000552 an ferror() call.
553
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000554- min() and max() now support key= arguments with the same meaning as in
555 list.sort().
556
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000557- The peephole optimizer now performs simple constant folding in expressions:
558 (2+3) --> (5).
559
Raymond Hettingera422c342005-01-11 03:03:27 +0000560- set and frozenset objects can now be marshalled. SF #1098985.
561
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000562- Bug #1077106: Poor argument checking could cause memory corruption
563 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000564
Jeremy Hyltonab630502005-02-04 18:44:06 +0000565- The parser did not complain about future statements in illegal
566 positions. It once again reports a syntax error if a future
567 statement occurs after anything other than a doc string.
568
Neil Schemenauercf52c072005-08-12 17:34:58 +0000569- Change the %s format specifier for str objects so that it returns a
570 unicode instance if the argument is not an instance of basestring and
571 calling __str__ on the argument returns a unicode instance.
572
Tim Petersf4e69282006-02-27 17:15:31 +0000573- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
574 current thread state when the auto-GIL-state machinery knows about
575 it (since the thread state is being deleted, continuing to remember it
576 can't help, but can hurt if another thread happens to get created with
577 the same thread id).
578
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000579Extension Modules
580-----------------
581
Georg Brandl43f08a82006-03-31 18:01:16 +0000582- Patch #1380952: fix SSL objects timing out on consecutive read()s
583
Neal Norwitz05a45592006-03-20 06:30:08 +0000584- Patch #1309579: wait3 and wait4 were added to the posix module.
585
Anthony Baxterfa869072006-03-20 05:21:58 +0000586- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
587 In addition, the existing ulaw code was updated.
588
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000589- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000590 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000591
Neal Norwitz10be10c2006-03-16 06:50:13 +0000592- Everything under lib-old was removed. This includes the following modules:
593 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000594 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000595 util, whatsound, whrandom, zmod
596
597- The following modules were removed: regsub, reconvert, regex, regex_syntax.
598
599- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000600 is deprecated. The undocumented re.engine variable no longer exists.
601
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000602- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
603 SS2 (single-shift 2) escape sequences correctly.
604
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000605- The unicodedata module was updated to the 4.1 version of the Unicode
606 database. The 3.2 version is still available as unicodedata.db_3_2_0

767-------
768
Nick Coghlan43832302006-04-23 17:04:07 +0000769- PEP 338: new module runpy defines a run_module function to support

Georg Brandl828fdef2006-04-01 08:59:03 +0000784 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000785 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000786 module will not be built.
787
Tim Petersc17976e2006-04-01 00:26:53 +0000788- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
789 aren't officially supported here, and trying to use them will probably
790 raise an exception some day. But dicts have been allowed, and "mostly
791 worked", so support for them won't go away without warning.
792
Georg Brandl338ef7d2006-03-31 18:42:16 +0000793- Bug #1445068: getpass.getpass() can now be given an explicit stream

811
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000812- email 4.0 package now integrated. This is largely the same as the email 3.0
813 package that was included in Python 2.3, except that PEP 8 module names are
814 now used (e.g. mail.message instead of email.Message). The MIME classes
815 have been moved to a subpackage (e.g. email.mime.text instead of
816 email.MIMEText). The old names are still supported for now. Several
817 deprecated Message methods have been removed and lots of bugs have been
818 fixed. More details can be found in the email package documentation.
819
Walter Dörwald40108c92006-03-27 08:15:44 +0000820- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
821 (a subclass of tuple) that provides incremental decoders and encoders
822 (a way to use stateful codecs without the stream API). Python functions
823 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
824 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
825 have been added.

828 a ValueError instead of a StopIteration now (like file and cString.String do).
829 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
830 called before (like file and StringIO.StringIO do).

898
Neal Norwitz338e7862005-12-23 21:27:46 +0000899- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
900 LoadError as documented, instead of IOError. For compatibility,
901 LoadError subclasses IOError.
902
Brett Cannon3cbd0382005-12-16 22:49:23 +0000903- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +0000904 SHA1, 224, 256, 384, and 512. Note that recent developments make the
905 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
906 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
907 Ronald L. Rivest offered this advice for Python:
908
909 "The consensus of researchers in this area (at least as
910 expressed at the NIST Hash Function Workshop 10/31/05),
911 is that SHA-256 is a good choice for the time being, but
912 that research should continue, and other alternatives may
913 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000914
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000915- Added a subset of Fredrik Lundh's ElementTree package. Available

968 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000969 correct line numbers for decoding errors in source code.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001007- The tokenize module now detects and reports indentation errors.
1008 Bug #1224621.
1009
Raymond Hettinger68c04532005-06-10 11:05:19 +00001010- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001011 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001012 the generate_tokens() function now accepts a callable argument that
1013 terminates by raising StopIteration.
1014
Georg Brandl9166e1a2005-06-04 09:20:03 +00001015- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1019
Skip Montanaro174dd222005-05-14 20:54:16 +00001020- Patch #1120353: The xmlrpclib module provides better, more transparent,

1023 class at all.
1024
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001025- distutils.commands.upload was added to support uploading distribution

1029 them to PyPI.
1030
Raymond Hettinger267b8682005-03-27 10:47:39 +00001031- decimal operator and comparison methods now return NotImplemented
1032 instead of raising a TypeError when interacting with other types. This
1033 allows other classes to implement __radd__ style methods and have them
1034 work as expected.
1035
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001036- Bug #1163325: Decimal infinities failed to hash. Attempting to
1037 hash a NaN raised an InvalidOperation instead of a TypeError.
1038
Tim Petersecc6e6a2005-07-10 22:30:55 +00001039- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001040 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1041

1052
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001053- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.

1073
Guido van Rossumd0641422005-02-03 15:01:24 +00001074- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1075 disables recursive traversal through instance attributes, which can
1076 be exploited in various ways.
1077
Tim Peterse3547fd2005-12-16 23:13:57 +00001078- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001079 flags on the HTTP listening socket.
1080
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001081- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1082 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1083
Tim Peterse3547fd2005-12-16 23:13:57 +00001084- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001085 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1086
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001087- Bug #1110478: Revert os.environ.update to do putenv again.
1088
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001089- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1090
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001091- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1092
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001093- Enhancements to the csv module:
1094
1095 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001096 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001097 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001098 + Dialect parameter parsing has been re-implemented to improve error
1099 reporting.
1100 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1101 dictates.
1102 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001103 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001104 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001105 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1106 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001107 + reader now allows \r characters to be quoted (previously it only allowed
1108 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001109 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001110 + Dialect classes passed to the module are no longer instantiated by
1111 the module before being parsed (the former validation scheme required
1112 this, but the mechanism was unreliable).
1113 + The dialect registry now contains instances of the internal
1114 C-coded dialect type, rather than references to python objects.
1115 + the internal c-coded dialect type is now immutable.
1116 + register_dialect now accepts the same keyword dialect specifications
1117 as the reader and writer, allowing the user to register dialects
1118 without first creating a dialect class.
1119 + a configurable limit to the size of parsed fields has been added -
1120 previously, an unmatched quote character could result in the entire
1121 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001122 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001123 the parser field size limit (returning the former limit). The initial
1124 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001125 + A line_num attribute has been added to the reader object, which tracks
1126 the number of lines read from the source iterator. This is not
1127 the same as the number of records returned, as records can span
1128 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001129 + reader and writer objects were not being registered with the cyclic-GC.
1130 This has been fixed.
1131
Brett Cannone6539c42005-01-08 02:43:53 +00001132- _DummyThread objects in the threading module now delete self.__block that is
1133 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1134 lock primitives tend to be limited in number and thus should not be wasted on
1135 a _DummyThread object. Fixes bug #1089632.
1136
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001137- The imghdr module now detects Exif files.
1138
Raymond Hettinger6065d322004-12-20 23:51:53 +00001139- StringIO.truncate() now correctly adjusts the size attribute.
1140 (Bug #951915).
1141
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001142- locale.py now uses an updated locale alias table (built using
1143 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1144 alias file); the encoding lookup was enhanced to use Python's

Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001146
Raymond Hettinger3557f422004-12-07 12:02:02 +00001147- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1148
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001149- the pickle module no longer accepts the deprecated None option in the
1150 args tuple returned by __reduce__().
1151
Brett Cannon84667c02004-12-07 03:25:18 +00001152- optparse now optionally imports gettext. This allows its use in setup.py.
1153
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001154- the pickle module no longer uses the deprecated bin parameter.
1155
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001156- the shelve module no longer uses the deprecated binary parameter.
1157
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001158- the pstats module no longer uses the deprecated ignore() method.
1159
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001160- the filecmp module no longer uses the deprecated use_statcache argument.
1161
Raymond Hettinger664347b2004-12-04 21:21:53 +00001162- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1163 extended or overridden by subclasses. Formerly, the subclassed method would
1164 be ignored by the rest of the module. (Bug #1078905).
1165
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001166- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001167 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001168
Walter Dörwald36733692004-12-22 12:50:50 +00001169- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1170 once when a size argument is given. This prevents a buffer overflow in the
1171 tokenizer with very long source lines.
1172
Barry Warsaw538561e2006-01-01 21:48:54 +00001173- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1174 immediately after creating the object, without any intervening
1175 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001176
Skip Montanaro05885812005-01-16 20:48:27 +00001177- The reconvert.quote function can now emit triple-quoted strings. The
1178 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001179
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001180- ``UserString.MutableString`` now supports negative indices in
1181 ``__setitem__`` and ``__delitem__``
1182
Greg Ward40407942005-03-05 02:53:17 +00001183- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1184 correctly.
1185
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001186- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1187 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1188 character even if the user has passed a size parameter to get a proper
1189 line ending. Remove the special handling of a "\r\n" that has been split
1190 between two lines.
1191
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001192- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1193 about illegal code points. The codec now supports PEP 293 style error
1194 handlers.
1195
Walter Dörwald78a78b02005-09-01 12:04:29 +00001196- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001197 from the input stream, so that the output is a byte string in the correct
1198 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001199
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001200- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1201 considering it exactly like a '*'.
1202
Walter Dörwald007f8df2005-10-09 19:42:27 +00001203- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1204 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001205
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001206- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1207
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001208- Patch #1413711: Certain patterns of differences were making difflib
1209 touch the recursion limit.
1210
Walter Dörwald58917a62006-03-31 15:26:22 +00001211- Bug #947906: An object oriented interface has been added to the calendar
1212 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001213 called as a script (e.g. via ``python -mcalendar``). Localized month and
1214 weekday names can be ouput (even if an exotic encoding is used) using
1215 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001216
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001217Build
1218-----
1219
Neal Norwitz602d3392006-03-31 08:21:40 +00001220- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1221 by using -mieee gcc option.
1222
Martin v. Löwis86d66262006-02-17 08:40:11 +00001223- Patch #1432345: Make python compile on DragonFly.
1224
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001225- Build support for Win64-AMD64 was added.
1226
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001227- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1228
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001229- Patch #881820: look for openpty and forkpty also in libbsd.
1230
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001231- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1232 The zlib module is now builtin on Windows.
1233
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001234- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1235
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001236- Bug #1189330: configure did not correctly determine the necessary
1237 value of LINKCC if python was built with GCC 4.0.
1238
Trent Mick8321b422005-07-26 02:29:21 +00001239- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1240 vulnerability in zlib 1.2.1 and 1.2.2.
1241
Brett Cannon08cd5982005-04-24 22:26:38 +00001242- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1243 flags that change binary compatibility. Changes were also made to
1244 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001245 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001246
Bob Ippolitoed233462005-03-29 13:47:59 +00001247- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1248 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1249 no longer exists). This configure patch makes things right.
1250
Martin v. Löwise2713be2005-03-08 15:03:08 +00001251- Bug #1158607: Build with --disable-unicode again.
1252
Brett Cannon46d96232005-02-16 00:07:19 +00001253- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1254 defined. Discovered as a result of not being able to build on OS X.
1255
Brett Cannon516592f2004-12-07 00:42:59 +00001256- setup.py now uses the directories specified in LDFLAGS using the -L option
1257 and in CPPFLAGS using the -I option for adding library and include
1258 directories, respectively, for compiling extension modules against. This has
1259 led to the core being compiled using the values in CPPFLAGS. It also removes
1260 the need for the special-casing of both DarwinPorts and Fink for darwin since
1261 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1262 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1263 Fink, ``-I/opt/local/include`` for DarwinPorts).
1264
Brett Cannon43802422005-02-10 20:48:03 +00001265- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1266 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1267 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1268 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001270C API
1271-----
1272
Tim Petersc9d78aa2006-03-26 23:27:58 +00001273- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1274 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1275 is obtained via the ``PyObject_`` family, it must be released via the
1276 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1277 always been officially true, but when Python's small-object allocator was
1278 introduced, an attempt was made to cater to a few extension modules
1279 discovered at the time that obtained memory via ``PyObject_New`` but
1280 released it via ``PyMem_DEL``. It's years later, and if such code still
1281 exists it will fail now (probably with segfaults, but calling wrong
1282 low-level memory management functions can yield many symptoms).
1283
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001284- Added a C API for set and frozenset objects.
1285
Raymond Hettinger66517482004-12-03 11:45:13 +00001286- Removed PyRange_New().
1287
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001288- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1289 mapping argument now. This string is used as a mapping table. Byte values
1290 greater than the length of the string and 0xFFFE are treated as undefined
1291 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001298
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001299- Patch #1276356: New resource "urlfetch" is implemented. This enables
1300 even impatient people to run tests that require remote files.
