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.

Neal Norwitz7a5fc282006-05-15 06:48:14 +000028Extension Modules
29-----------------
30
Georg Brandl8d3342b2006-05-16 07:38:27 +000031- Patch #1435422: zlib's compress and decompress objects now have a
32 copy() method.
33
Neal Norwitz7a5fc282006-05-15 06:48:14 +000034- On Win32, os.listdir now supports arbitrarily-long Unicode path names
35 (up to the system limit of 32K characters).
36
37- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
38 As a result, these functions now raise WindowsError instead of OSError.
39
40- Calling Tk_Init twice is refused if the first call failed as that
41 may deadlock.
42
43Library
44-------
45
Georg Brandl49c8f4c2006-05-15 19:30:35 +000046- Patch #1488881: add support for external file objects in bz2 compressed
47 tarfiles.
48
Neal Norwitz7a5fc282006-05-15 06:48:14 +000049- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
50 stdout arguments, making it possible to redirect input and output
51 for remote debugging.
52
53- Patch #1484695: Update the tarfile module to version 0.8. This fixes
54 a couple of issues, notably handling of long file names using the
55 GNU LONGNAME extension.
56
57- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
58 new flag when ``name`` is already the name of an option flag.
59
60- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
61 package.
62
63- Patch #1472854: make the rlcompleter.Completer class usable on non-
64 UNIX platforms.

90Core and builtins
91-----------------
92
Thomas Heller1b046642006-04-18 18:51:06 +000093- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
94 by converting these apis from macros into exported functions again:
95
96 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
97 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
98 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
99 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
100 PyRun_String Py_CompileString
101
Martin v. Löwis45294a92006-04-18 06:24:08 +0000102- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
103
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000104- All uses of PyStructSequence_InitType have been changed to initialize
105 the type objects only once, even if the interpreter is initialized
106 multiple times.
107
Neal Norwitz61546162006-04-14 05:20:28 +0000108- Bug #1454485, array.array('u') could crash the interpreter. This was
109 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
110 to unicode when it didn't make sense. 'u#' now requires a unicode string.
111
112- Py_UNICODE is unsigned. It was always documented as unsigned, but
113 due to a bug had a signed value in previous versions.
114
Tim Peters3a5e8b12006-04-11 01:44:07 +0000115- Patch #837242: ``id()`` of any Python object always gives a positive
116 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
117 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000118 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000119 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000120
Tim Peters3a5e8b12006-04-11 01:44:07 +0000121 def __hash__(self):
122 return id(self) # WRONG
123
124 because a hash result must be a (short) Python int but it was always
125 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000126 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000127 was always usable as a hash value before this patch. That's no longer
128 necessarily so.
129
130- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000131 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000132 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000133 #1454844)
134
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000135- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
136 involving generators that have paused outside of any ``try`` or ``with``
137 blocks. (In 2.5a1, a paused generator that was part of a reference
138 cycle could not be garbage collected, regardless of whether it was
139 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000141Extension Modules
142-----------------
143
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000144- Patch #1191065: Fix preprocessor problems on systems where recvfrom
145 is a macro.
146
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000147- Bug #1467952: os.listdir() now correctly raises an error if readdir()
148 fails with an error condition.
149
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000150- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
151
152- Bug #1117761: bsddb.*open() no longer raises an exception when using
153 the cachesize parameter.
154
155- Bug #1149413: bsddb.*open() no longer raises an exception when using
156 a temporary db (file=None) with the 'n' flag to truncate on open.
157
158- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
159 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000160
Armin Rigoa9017c32006-04-19 11:50:27 +0000161- Patch #1062014: AF_UNIX sockets under Linux have a special
162 abstract namespace that is now fully supported.
163
Anthony Baxter51bcb682006-04-05 14:51:42 +0000164Library
165-------
166
Tim Peters711bf302006-04-25 03:31:36 +0000167- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
168 a doctest to be skipped (the code is not run, and the expected output
169 or exception is ignored).
170
Nick Coghlanda2268f2006-04-24 04:37:15 +0000171- Fixed contextlib.nested to cope with exceptions being raised and
172 caught inside exit handlers.
173
Greg Wardab05edc2006-04-23 03:47:58 +0000174- Updated optparse module to Optik 1.5.1 (allow numeric constants in
175 hex, octal, or binary; add ``append_const`` action; keep going if
176 gettext cannot be imported; added ``OptionParser.destroy()`` method;
177 added ``epilog`` for better help generation).
178
Tim Peters21fbd572006-04-21 21:18:10 +0000179- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
180 called from a thread spawned as a side effect of importing a module.
181
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000182- The pydoc module now supports documenting packages contained in
183 .zip or .egg files.
184
185- The pkgutil module now has several new utility functions, such
186 as ``walk_packages()`` to support working with packages that are either
187 in the filesystem or zip files.
188
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000189- The mailbox module can now modify and delete messages from
190 mailboxes, in addition to simply reading them. Thanks to Gregory
191 K. Johnson for writing the code, and to the 2005 Google Summer of
192 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000193
Tim Petersc7605f22006-04-17 21:12:33 +0000194- The ``__del__`` method of class ``local`` in module ``_threading_local``
195 returned before accomplishing any of its intended cleanup.
196
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000197- Patch #790710: Add breakpoint command lists in pdb.
198
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000199- Patch #1063914: Add Tkinter.Misc.clipboard_get().
200
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000201- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
202
Anthony Baxtere29002c2006-04-12 12:07:31 +0000203- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
204 Windows. Bug #1469163.
205
Phillip J. Eby47032112006-04-11 01:07:43 +0000206- The warnings, linecache, inspect, traceback, site, and doctest modules
207 were updated to work correctly with modules imported from zipfiles or
208 via other PEP 302 __loader__ objects.
209
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000210- Patch #1467770: Reduce usage of subprocess._active to processes which
211 the application hasn't waited on.
212
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000213- Patch #1462222: Fix Tix.Grid.
214
Neal Norwitza31bf182006-04-09 03:35:43 +0000215- Fix exception when doing glob.glob('anything*/')
216
Skip Montanaro262fb922006-04-21 02:31:07 +0000217- The pstats.Stats class accepts an optional stream keyword argument to
218 direct output to an alternate file-like object.
219
Anthony Baxter51bcb682006-04-05 14:51:42 +0000220Build
221-----
222
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000223- The Makefile now has a reindent target, which runs reindent.py on
224 the library.
225
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000226- Patch #1470875: Building Python with MS Free Compiler
227
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000228- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000229
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000230- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
231 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000232 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000233 CXX from --with-cxx-main, see description in README.
234
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000235- Patch #1429775: Link extension modules with the shared libpython.
236
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000237- Fixed a libffi build problem on MIPS systems.
238
Tim Peters8931ff12006-05-13 23:28:20 +0000239- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
240 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
241 and "%zu" for unsigned integers of type ``size_t``.

245
Nick Coghlanda2268f2006-04-24 04:37:15 +0000246- test_contextlib now checks contextlib.nested can cope with exceptions
247 being raised and caught inside exit handlers.
248
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000249- test_cmd_line now checks operation of the -m and -c command switches
250
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000251- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
252 it separately and by hand. It also wasn't cleaning up its changes to
253 the current Decimal context.
254
Thomas Woutersabd08882006-04-26 15:53:30 +0000255- regrtest.py now has a -M option to run tests that test the new limits of
256 containers, on 64-bit architectures. Running these tests is only sensible
257 on 64-bit machines with more than two gigabytes of memory. The argument
258 passed is the maximum amount of memory for the tests to use.

Nick Coghlanc195d8a2006-04-24 03:04:43 +0000271- PEP 343: Added Context Types section to the library reference
272 and attempted to bring other PEP 343 related documentation into
273 line with the implementation and/or python-dev discussions.
274
Tim Peters8dc73d22006-04-24 02:03:16 +0000275- Bug #1337990: clarified that ``doctest`` does not support examples

Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000283
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000284Core and builtins
285-----------------
286
Nick Coghlan43832302006-04-23 17:04:07 +0000287- PEP 338: -m command line switch now delegates to runpy.run_module
288 allowing it to support modules in packages and zipfiles
289
Martin v. Löwisc661b882006-04-20 04:54:23 +0000290- On Windows, .DLL is not an accepted file name extension for
291 extension modules anymore; extensions are only found if they
292 end in .PYD.
293
Martin v. Löwisea62d252006-04-03 10:56:49 +0000294- Bug #1421664: sys.stderr.encoding is now set to the same value as
295 sys.stdout.encoding.
296
Neal Norwitz92e212f2006-04-03 04:48:37 +0000297- __import__ accepts keyword arguments.
298
Georg Brandlccadf842006-03-31 18:54:53 +0000299- Patch #1460496: round() now accepts keyword arguments.
300
Anthony Baxter262c00a2006-03-30 10:53:17 +0000301- Fixed bug #1459029 - unicode reprs were double-escaped.
302
Hye-Shik Changd478f342006-03-23 12:32:36 +0000303- Patch #1396919: The system scope threads are reenabled on FreeBSD
304 5.4 and later versions.
305
Neal Norwitze98ccf62006-03-23 05:39:47 +0000306- Bug #1115379: Compiling a Unicode string with an encoding declaration
307 now gives a SyntaxError.
308
Georg Brandlabd1ff82006-03-18 07:59:59 +0000309- Previously, Python code had no easy way to access the contents of a
310 cell object. Now, a ``cell_contents`` attribute has been added
311 (closes patch #1170323).
312
Tim Peterscf79aac2006-03-16 01:14:46 +0000313- Patch #1123430: Python's small-object allocator now returns an arena to
314 the system ``free()`` when all memory within an arena becomes unused
315 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
316 freed. Some applications will see a drop in virtual memory size now,
317 especially long-running applications that, from time to time, temporarily
318 use a large number of small objects. Note that when Python returns an
319 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000320 platform C library will in turn return that memory to the operating system.
321 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000322 appears to be effective at least on Microsoft C and gcc-based systems.
323 Thanks to Evan Jones for hard work and patience.
324
Georg Brandl533ff6f2006-03-08 18:09:27 +0000325- Patch #1434038: property() now uses the getter's docstring if there is
326 no "doc" argument given. This makes it possible to legitimately use
327 property() as a decorator to produce a read-only property.
328
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000329- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
330 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
331 of requiring an int or long in slicing and a few other contexts, enabling
332 other objects (e.g. Numeric Python's integers) to be used as slice indices.
333
Neal Norwitz995acdf2006-03-07 05:01:00 +0000334- Fixed various bugs reported by Coverity's Prevent tool.
335
Brett Cannonbf364092006-03-01 04:25:17 +0000336- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
337 new exception base class, BaseException, which has a new message attribute.
338 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
339 Raising a string exception now raises a DeprecationWarning.
340
Thomas Woutersfb609f42006-02-28 16:37:25 +0000341- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
342 explicitly relative, using 'from .module import name' to mean 'from the same
343 package as this module is in. Imports without dots still default to the
344 old relative-then-absolute, unless 'from __future__ import
345 absolute_import' is used.
346
Brett Cannona7446e32006-02-27 23:39:10 +0000347- Properly check if 'warnings' raises an exception (usually when a filter set
348 to "error" is triggered) when raising a warning for raising string
349 exceptions.
350
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000351- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000352 The name was removed from Include/code.h.
353
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000354- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000355
Guido van Rossum1968ad32006-02-25 22:38:04 +0000356- Patch 1433928:
357 - The copy module now "copies" function objects (as atomic objects).
358 - dict.__getitem__ now looks for a __missing__ hook before raising
359 KeyError.
360
Tim Peters84ef21c2006-02-28 20:39:06 +0000361- PEP 343: with statement implemented. Needs ``from __future__ import
362 with_statement``. Use of 'with' as a variable will generate a warning.
363 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000364 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000365 The following objects have __context__ methods:
366 - The built-in file type.
367 - The thread.LockType type.
368 - The following types defined by the threading module:
369 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
370 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000371
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000372- Fix the encodings package codec search function to only search
373 inside its own package. Fixes problem reported in patch #1433198.
374
375 Note: Codec packages should implement and register their own
376 codec search function. PEP 100 has the details.
377
Martin v. Löwis18e16552006-02-15 17:27:45 +0000378- PEP 353: Using ssize_t as the index type.
379
Neal Norwitzfc76d632006-01-10 06:03:13 +0000380- Patch #1400181, fix unicode string formatting to not use the locale.
381 This is how string objects work. u'%f' could use , instead of .
382 for the decimal point. Now both strings and unicode always use periods.
383
Neal Norwitz671b9e32006-01-09 07:07:12 +0000384- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
385 configure would break checking curses.h.
386
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000387- Bug #959576: The pwd module is now builtin. This allows Python to be
388 built on UNIX platforms without $HOME set.
389
Neal Norwitzc10978f2005-12-19 06:07:16 +0000390- Bug #1072182, fix some potential problems if characters are signed.
391
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000392- Bug #889500, fix line number on SyntaxWarning for global declarations.
393
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000394- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
395
Neal Norwitze7214a12005-12-18 05:03:17 +0000396- Support for converting hex strings to floats no longer works.
397 This was not portable. float('0x3') now raises a ValueError.
398
Barry Warsaw2a38a862005-12-18 01:27:35 +0000399- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000400 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000401 is now displayed in interactive prompt banner.
402
Georg Brandlfa166682005-12-17 21:45:17 +0000403- Implementation of PEP 341 - Unification of try/except and try/finally.
404 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000405 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000406
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000407- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
408 now encodes backslash correctly.
409
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000410- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
411
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000412- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000413 and long longs.
414
Neal Norwitz67715f02005-11-09 06:59:35 +0000415- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000416 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000417 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000418
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000419- Replaced most Unicode charmap codecs with new ones using the
420 new Unicode translate string feature in the builtin charmap
421 codec; the codecs were created from the mapping tables available
422 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
423 encodings now include a mapping for the Apple logo)
424
Tim Peterse3547fd2005-12-16 23:13:57 +0000425- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000426
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000427- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000428
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000429- A new AST parser implementation was completed. The abstract
430 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000431 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000432
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000433- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000434 The following code now raises a SyntaxError: foo(a = i for i in range(10))
435
Neal Norwitz708e51a2005-10-03 04:48:15 +0000436- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
437
Neal Norwitz11bd1192005-10-03 00:54:56 +0000438- SF Bug #887946: fix segfault when redirecting stdin from a directory.
439 Provide a warning when a directory is passed on the command line.
440
Neal Norwitz40d37812005-10-02 01:48:49 +0000441- Fix segfault with invalid coding.
442
443- SF bug #772896: unknown encoding results in MemoryError.
444
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000445- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000446 supported a __len__() method which evaluated to False when the iterator
447 was empty.
448
Guido van Rossum630db602005-09-20 18:49:54 +0000449- On 64-bit platforms, when __len__() returns a value that cannot be
450 represented as a C int, raise OverflowError.
451
Skip Montanarof8948ca2005-09-19 03:54:46 +0000452- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000453 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000454
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000455- SF bug #893549: parsing keyword arguments was broken with a few format
456 codes.
457
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000458- Changes donated by Elemental Security to make it work on AIX 5.3
459 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
460 bug #105470: test_pwd fails on 64bit system (Opteron).
461
Guido van Rossum539c6622005-09-14 17:49:54 +0000462- Changes donated by Elemental Security to make it work on HP-UX 11 on
463 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
464
Georg Brandl4550b8d2005-08-26 06:43:52 +0000465- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000466 (fixes bug #1119418).
467
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000468- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
469
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000470- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
471 exceptions that cause a function to exit.
472
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000473- The implementation of set() and frozenset() was revised to use its
474 own internal data structure. Memory consumption is reduced by 1/3
475 and there are modest speed-ups as well. The API is unchanged.
476
Tim Petersde7990b2005-07-17 23:45:23 +0000477- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
478
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000479- SF bug #1229429: PyObject_CallMethod failed to decrement some
480 reference counts in some error exit cases.
481
Tim Petersecc6e6a2005-07-10 22:30:55 +0000482- SF bug #1185883: Python's small-object memory allocator took over
483 a block managed by the platform C library whenever a realloc specified
484 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000485 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000486 portable way to copy data from the C-managed block into Python's
487 small-object space without risking a memory fault. Python's small-object
488 realloc now leaves such blocks under the control of the platform C
489 realloc.
490
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000491- SF bug #1232517: An overflow error was not detected properly when
492 attempting to convert a large float to an int in os.utime().
493
Raymond Hettinger3296e692005-06-29 23:29:56 +0000494- SF bug #1224347: hex longs now print with lowercase letters just
495 like their int counterparts.
496
Michael W. Hudson188d4362005-06-20 16:52:57 +0000497- SF bug #1163563: the original fix for bug #1010677 ("thread Module
498 Breaks PyGILState_Ensure()") broke badly in the case of multiple
499 interpreter states; back out that fix and do a better job (see
500 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
501 for a longer write-up of the problem).
502
Michael W. Hudsondf888462005-06-03 14:41:55 +0000503- SF patch #1180995: marshal now uses a binary format by default when
504 serializing floats.
505
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000506- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
507 the routines that promise to produce IEEE 754 binary representations
508 of floats now simply copy bytes around.
509
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000510- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
511 278.
512
Brett Cannonc3647ac2005-04-26 03:45:26 +0000513- patch #1109424: int, long, float, complex, and unicode now check for the
514 proper magic slot for type conversions when subclassed. Previously the
515 magic slot was ignored during conversion. Semantics now match the way
516 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000517 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000518 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000519 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000520
Barry Warsawc8d907c2005-04-19 23:43:40 +0000521- Descriptors defined in C with a PyGetSetDef structure, where the setter is
522 NULL, now raise an AttributeError when attempting to set or delete the
523 attribute. Previously a TypeError was raised, but this was inconsistent
524 with the equivalent pure-Python implementation.
525
Michael W. Hudson774479c2005-04-18 08:46:17 +0000526- It is now safe to call PyGILState_Release() before
527 PyEval_InitThreads() (note that if there is reason to believe there
528 are multiple threads around you still must call PyEval_InitThreads()
529 before using the Python API; this fix is for extension modules that
530 have no way of knowing if Python is multi-threaded yet).
531
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000532- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
533 disabled caused a crash.
534
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000535- Bug #1165306: instancemethod_new allowed the creation of a method
536 with im_class == im_self == NULL, which caused a crash when called.
537
Tim Petersecc6e6a2005-07-10 22:30:55 +0000538- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000539 fixes the crash seen in bug #1165761
540
Raymond Hettinger96229b12005-03-11 06:49:40 +0000541- Added two new builtins, any() and all().
542
Brett Cannon409d8f22005-03-05 06:47:57 +0000543- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000544 (e.g., ``class C(): pass`` is no longer a syntax error).
545 Patch #1176012 added support to the 'parser' module and 'compiler' package
546 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000547
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000548- Patch #1115086: Support PY_LONGLONG in structmember.
549
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000550- Bug #1155938: new style classes did not check that __init__() was
551 returning None.
552
Tim Petersecc6e6a2005-07-10 22:30:55 +0000553- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000554 ('\') with a specific error message.
555
Martin v. Löwisff232d72005-03-03 09:24:38 +0000556- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
557
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000558- Bug #1124295: the __name__ attribute of file objects was
559 inadvertently made inaccessible in restricted mode.
560
Tim Petersecc6e6a2005-07-10 22:30:55 +0000561- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000562 an ferror() call.
563
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000564- min() and max() now support key= arguments with the same meaning as in
565 list.sort().
566
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000567- The peephole optimizer now performs simple constant folding in expressions:
568 (2+3) --> (5).
569
Raymond Hettingera422c342005-01-11 03:03:27 +0000570- set and frozenset objects can now be marshalled. SF #1098985.
571
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000572- Bug #1077106: Poor argument checking could cause memory corruption
573 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000574
Jeremy Hyltonab630502005-02-04 18:44:06 +0000575- The parser did not complain about future statements in illegal
576 positions. It once again reports a syntax error if a future
577 statement occurs after anything other than a doc string.
578
Neil Schemenauercf52c072005-08-12 17:34:58 +0000579- Change the %s format specifier for str objects so that it returns a
580 unicode instance if the argument is not an instance of basestring and
581 calling __str__ on the argument returns a unicode instance.
582
Tim Petersf4e69282006-02-27 17:15:31 +0000583- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
584 current thread state when the auto-GIL-state machinery knows about
585 it (since the thread state is being deleted, continuing to remember it
586 can't help, but can hurt if another thread happens to get created with
587 the same thread id).
588
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000589Extension Modules
590-----------------
591
Georg Brandl43f08a82006-03-31 18:01:16 +0000592- Patch #1380952: fix SSL objects timing out on consecutive read()s
593
Neal Norwitz05a45592006-03-20 06:30:08 +0000594- Patch #1309579: wait3 and wait4 were added to the posix module.
595
Anthony Baxterfa869072006-03-20 05:21:58 +0000596- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
597 In addition, the existing ulaw code was updated.
598
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000599- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000600 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000601
Neal Norwitz10be10c2006-03-16 06:50:13 +0000602- Everything under lib-old was removed. This includes the following modules:

777-------
778
Nick Coghlan43832302006-04-23 17:04:07 +0000779- PEP 338: new module runpy defines a run_module function to support
780 executing modules which provide access to source code or a code object
781 via the PEP 302 import mechanisms.

Georg Brandl828fdef2006-04-01 08:59:03 +0000794 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000795 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000796 module will not be built.
797
Tim Petersc17976e2006-04-01 00:26:53 +0000798- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
799 aren't officially supported here, and trying to use them will probably
800 raise an exception some day. But dicts have been allowed, and "mostly
801 worked", so support for them won't go away without warning.
802
Georg Brandl338ef7d2006-03-31 18:42:16 +0000803- Bug #1445068: getpass.getpass() can now be given an explicit stream

821
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000822- email 4.0 package now integrated. This is largely the same as the email 3.0
823 package that was included in Python 2.3, except that PEP 8 module names are
824 now used (e.g. mail.message instead of email.Message). The MIME classes
825 have been moved to a subpackage (e.g. email.mime.text instead of
826 email.MIMEText). The old names are still supported for now. Several
827 deprecated Message methods have been removed and lots of bugs have been
828 fixed. More details can be found in the email package documentation.
829
Walter Dörwald40108c92006-03-27 08:15:44 +0000830- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
831 (a subclass of tuple) that provides incremental decoders and encoders
832 (a way to use stateful codecs without the stream API). Python functions
833 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
834 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
835 have been added.

838 a ValueError instead of a StopIteration now (like file and cString.String do).
839 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
840 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000841

888
Tim Petersda1329b2006-02-27 16:50:01 +0000889- Patch #1349118: urllib now supports user:pass@ style proxy
Martin v. Löwis3e865952006-01-24 15:51:21 +0000890 specifications, raises IOErrors when proxies for unsupported protocols
891 are defined, and uses the https proxy on https redirections.

908
Neal Norwitz338e7862005-12-23 21:27:46 +0000909- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
910 LoadError as documented, instead of IOError. For compatibility,
911 LoadError subclasses IOError.
912
Brett Cannon3cbd0382005-12-16 22:49:23 +0000913- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +0000914 SHA1, 224, 256, 384, and 512. Note that recent developments make the
915 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
916 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
917 Ronald L. Rivest offered this advice for Python:
918
919 "The consensus of researchers in this area (at least as
920 expressed at the NIST Hash Function Workshop 10/31/05),
921 is that SHA-256 is a good choice for the time being, but
922 that research should continue, and other alternatives may
923 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000924
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000925- Added a subset of Fredrik Lundh's ElementTree package. Available

976
Martin v. Löwis56066d22005-08-24 07:38:12 +0000977- Bug #1178484: Return complete lines from codec stream readers
978 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000979 correct line numbers for decoding errors in source code.

996 parameter, but uses the usual "kwargs=None".
997
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000998- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +0000999 Patch #1209527 (Contributed by Connelly).
1000

1002 to W3C name (404 -> 'Not Found'). RFE #1216944.
1003
Georg Brandl9e43acf2005-07-04 17:16:07 +00001004- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1005 as this can cause problems with apps closing all file descriptors.

1011
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001012- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1013 error messages.
1014
Georg Brandl379f99d2005-06-26 21:09:38 +00001015- Bug #1108948: Cookie.py produced invalid JavaScript code.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001017- The tokenize module now detects and reports indentation errors.
1018 Bug #1224621.
1019
Raymond Hettinger68c04532005-06-10 11:05:19 +00001020- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001021 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001022 the generate_tokens() function now accepts a callable argument that
1023 terminates by raising StopIteration.
1024
Georg Brandl9166e1a2005-06-04 09:20:03 +00001025- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1029
Skip Montanaro174dd222005-05-14 20:54:16 +00001030- Patch #1120353: The xmlrpclib module provides better, more transparent,

1033 class at all.
1034
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001035- distutils.commands.upload was added to support uploading distribution

1039 them to PyPI.
1040
Raymond Hettinger267b8682005-03-27 10:47:39 +00001041- decimal operator and comparison methods now return NotImplemented
1042 instead of raising a TypeError when interacting with other types. This
1043 allows other classes to implement __radd__ style methods and have them
1044 work as expected.
1045
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001046- Bug #1163325: Decimal infinities failed to hash. Attempting to
1047 hash a NaN raised an InvalidOperation instead of a TypeError.
1048
Tim Petersecc6e6a2005-07-10 22:30:55 +00001049- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1083
Guido van Rossumd0641422005-02-03 15:01:24 +00001084- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1085 disables recursive traversal through instance attributes, which can
1086 be exploited in various ways.
1087
Tim Peterse3547fd2005-12-16 23:13:57 +00001088- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001089 flags on the HTTP listening socket.
1090
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001091- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1092 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1093
Tim Peterse3547fd2005-12-16 23:13:57 +00001094- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001095 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1096

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001099- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1100
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001101- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1102
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001103- Enhancements to the csv module:
1104
1105 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001106 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001107 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001108 + Dialect parameter parsing has been re-implemented to improve error
1109 reporting.
1110 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1111 dictates.
1112 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001113 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001114 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001115 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1116 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001117 + reader now allows \r characters to be quoted (previously it only allowed
1118 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001119 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001120 + Dialect classes passed to the module are no longer instantiated by
1121 the module before being parsed (the former validation scheme required
1122 this, but the mechanism was unreliable).
1123 + The dialect registry now contains instances of the internal
1124 C-coded dialect type, rather than references to python objects.
1125 + the internal c-coded dialect type is now immutable.
1126 + register_dialect now accepts the same keyword dialect specifications
1127 as the reader and writer, allowing the user to register dialects
1128 without first creating a dialect class.
1129 + a configurable limit to the size of parsed fields has been added -
1130 previously, an unmatched quote character could result in the entire
1131 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001132 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001133 the parser field size limit (returning the former limit). The initial
1134 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001135 + A line_num attribute has been added to the reader object, which tracks
1136 the number of lines read from the source iterator. This is not
1137 the same as the number of records returned, as records can span
1138 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001139 + reader and writer objects were not being registered with the cyclic-GC.
1140 This has been fixed.
1141
Brett Cannone6539c42005-01-08 02:43:53 +00001142- _DummyThread objects in the threading module now delete self.__block that is
1143 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1144 lock primitives tend to be limited in number and thus should not be wasted on
1145 a _DummyThread object. Fixes bug #1089632.
1146
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001147- The imghdr module now detects Exif files.
1148
Raymond Hettinger6065d322004-12-20 23:51:53 +00001149- StringIO.truncate() now correctly adjusts the size attribute.
1150 (Bug #951915).
1151
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001152- locale.py now uses an updated locale alias table (built using
1153 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1154 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001155 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001156
Raymond Hettinger3557f422004-12-07 12:02:02 +00001157- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1158
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001159- the pickle module no longer accepts the deprecated None option in the
1160 args tuple returned by __reduce__().
1161
Brett Cannon84667c02004-12-07 03:25:18 +00001162- optparse now optionally imports gettext. This allows its use in setup.py.
1163
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001164- the pickle module no longer uses the deprecated bin parameter.
1165
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001166- the shelve module no longer uses the deprecated binary parameter.

1169
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001170- the filecmp module no longer uses the deprecated use_statcache argument.
1171
Raymond Hettinger664347b2004-12-04 21:21:53 +00001172- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1173 extended or overridden by subclasses. Formerly, the subclassed method would
1174 be ignored by the rest of the module. (Bug #1078905).
1175
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001176- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001177 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001178
Walter Dörwald36733692004-12-22 12:50:50 +00001179- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1180 once when a size argument is given. This prevents a buffer overflow in the
1181 tokenizer with very long source lines.
1182
Barry Warsaw538561e2006-01-01 21:48:54 +00001183- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1184 immediately after creating the object, without any intervening
1185 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001186
Skip Montanaro05885812005-01-16 20:48:27 +00001187- The reconvert.quote function can now emit triple-quoted strings. The
1188 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001189
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001190- ``UserString.MutableString`` now supports negative indices in
1191 ``__setitem__`` and ``__delitem__``
1192
Greg Ward40407942005-03-05 02:53:17 +00001193- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1194 correctly.
1195
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001196- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1197 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1198 character even if the user has passed a size parameter to get a proper
1199 line ending. Remove the special handling of a "\r\n" that has been split
1200 between two lines.
1201
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001202- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1203 about illegal code points. The codec now supports PEP 293 style error
1204 handlers.
1205
Walter Dörwald78a78b02005-09-01 12:04:29 +00001206- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001207 from the input stream, so that the output is a byte string in the correct
1208 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001209
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001210- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1211 considering it exactly like a '*'.
1212
Walter Dörwald007f8df2005-10-09 19:42:27 +00001213- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1214 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001215
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001216- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1217
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001218- Patch #1413711: Certain patterns of differences were making difflib
1219 touch the recursion limit.
1220
Walter Dörwald58917a62006-03-31 15:26:22 +00001221- Bug #947906: An object oriented interface has been added to the calendar
1222 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001223 called as a script (e.g. via ``python -mcalendar``). Localized month and
1224 weekday names can be ouput (even if an exotic encoding is used) using
1225 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001226
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001227Build
1228-----
1229
Neal Norwitz602d3392006-03-31 08:21:40 +00001230- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1231 by using -mieee gcc option.
1232

1234
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001235- Build support for Win64-AMD64 was added.
1236
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001237- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1238
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001239- Patch #881820: look for openpty and forkpty also in libbsd.
1240
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001241- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1242 The zlib module is now builtin on Windows.
1243
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001244- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1245
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001246- Bug #1189330: configure did not correctly determine the necessary
1247 value of LINKCC if python was built with GCC 4.0.
1248
Trent Mick8321b422005-07-26 02:29:21 +00001249- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1250 vulnerability in zlib 1.2.1 and 1.2.2.
1251
Brett Cannon08cd5982005-04-24 22:26:38 +00001252- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1253 flags that change binary compatibility. Changes were also made to
1254 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001255 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001256
Bob Ippolitoed233462005-03-29 13:47:59 +00001257- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1258 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1259 no longer exists). This configure patch makes things right.
1260
Martin v. Löwise2713be2005-03-08 15:03:08 +00001261- Bug #1158607: Build with --disable-unicode again.
1262
Brett Cannon46d96232005-02-16 00:07:19 +00001263- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1264 defined. Discovered as a result of not being able to build on OS X.
1265
Brett Cannon516592f2004-12-07 00:42:59 +00001266- setup.py now uses the directories specified in LDFLAGS using the -L option
1267 and in CPPFLAGS using the -I option for adding library and include
1268 directories, respectively, for compiling extension modules against. This has
1269 led to the core being compiled using the values in CPPFLAGS. It also removes
1270 the need for the special-casing of both DarwinPorts and Fink for darwin since
1271 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1272 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1273 Fink, ``-I/opt/local/include`` for DarwinPorts).
1274
Brett Cannon43802422005-02-10 20:48:03 +00001275- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1276 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1277 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1278 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001280C API
1281-----
1282
Tim Petersc9d78aa2006-03-26 23:27:58 +00001283- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1284 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1285 is obtained via the ``PyObject_`` family, it must be released via the
1286 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1287 always been officially true, but when Python's small-object allocator was
1288 introduced, an attempt was made to cater to a few extension modules
1289 discovered at the time that obtained memory via ``PyObject_New`` but
1290 released it via ``PyMem_DEL``. It's years later, and if such code still
1291 exists it will fail now (probably with segfaults, but calling wrong
1292 low-level memory management functions can yield many symptoms).
1293
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001294- Added a C API for set and frozenset objects.
1295
Raymond Hettinger66517482004-12-03 11:45:13 +00001296- Removed PyRange_New().
1297
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001298- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1299 mapping argument now. This string is used as a mapping table. Byte values
1300 greater than the length of the string and 0xFFFE are treated as undefined
1301 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001308
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001309- Patch #1276356: New resource "urlfetch" is implemented. This enables
