Nick Coghlanc649ec52006-05-29 12:43:05 +00007What's New in Python 2.5 beta 1?
Anthony Baxter51bcb682006-04-05 14:51:42 +00008=================================
9
Nick Coghlanc649ec52006-05-29 12:43:05 +000010*Release date: XX-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Georg Brandlb7c8f542006-05-27 12:30:25 +000015- Builtin exceptions are now full-blown new-style classes instead of
16 instances pretending to be classes, which speeds up exception handling
17 by about 80% in comparison to 2.5a2.
18
Martin v. Löwisd004fc82006-05-27 08:36:52 +000019- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
20 Unicode 4.1.
21
Georg Brandlf4ef1162006-05-26 18:03:31 +000022- Patch #921466: sys.path_importer_cache is now used to cache valid and
23 invalid file paths for the built-in import machinery which leads to
24 fewer open calls on startup.
25
Tim Peters696cf432006-05-24 21:10:40 +000026- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
27 of-2 bases. The largest speedup is for inputs with about 1000 decimal
28 digits. Conversion from non-power-of-2 bases remains quadratic-time in
29 the number of input digits (it was and remains linear-time for bases
30 2, 4, 8, 16 and 32).
31
Tim Petersb713ec22006-05-23 18:45:30 +000032- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
33 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
34 an integer close to ``sys.maxint``. This was repaired by patch
35 #1335972, which also gives a nice speedup.
36
Richard Jonescebbefc2006-05-23 18:28:17 +000037- Patch #1337051: reduced size of frame objects.
38
39- PyErr_NewException now accepts a tuple of base classes as its
40 "base" parameter.
41
Richard Jones7c88dcc2006-05-23 10:37:38 +000042- Patch #876206: function call speedup by retaining allocated frame
43 objects.
44
Georg Brandl7b90e162006-05-18 07:01:27 +000045- Bug #1462152: file() now checks more thoroughly for invalid mode
46 strings and removes a possible "U" before passing the mode to the
47 C library function.
48
Neal Norwitz1004a532006-05-15 07:17:23 +000049- Patch #1488312, Fix memory alignment problem on SPARC in unicode
50
Neal Norwitz373f0a72006-05-15 07:04:36 +000051- Bug #1487966: Fix SystemError with conditional expression in assignment
52
Martin v. Löwis879768d2006-05-11 13:28:43 +000053- WindowsError now has two error code attributes: errno, which carries
54 the error values from errno.h, and winerror, which carries the error
55 values from winerror.h. Previous versions put the winerror.h values
56 (from GetLastError()) into the errno attribute.
57
Martin v. Löwis77736712006-05-04 05:51:03 +000058- Patch #1475845: Raise IndentationError for unexpected indent.
59
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000060- Patch #1479181: split open() and file() from being aliases for each other.
61
Tim Peters44bd9862006-06-01 13:49:23 +000062- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
63 methods were always silently ignored by dictionaries when comparing keys.
64 They are now passed through (except when using the C API function
65 ``PyDict_GetItem()``, whose semantics did not change).
66
67- Bug #1456209: In some obscure cases it was possible for a class with a
68 custom ``__eq__()`` method to confuse dict internals when class instances
69 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
70 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +000072Extension Modules
73-----------------
74
Nick Coghlanc649ec52006-05-29 12:43:05 +000075- Patch #1478788 (modified version): The functional extension module has
76 been renamed to _functools and a functools Python wrapper module added.
77 This provides a home for additional function related utilities that are
78 not specifically about functional programming. See PEP 309.
79
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000080- Patch #1493701: performance enhancements for struct module.
81
Georg Brandl378d5922006-05-17 14:26:50 +000082- Patch #1490224: time.altzone is now set correctly on Cygwin.
83
Georg Brandl8d3342b2006-05-16 07:38:27 +000084- Patch #1435422: zlib's compress and decompress objects now have a
85 copy() method.
86
Andrew MacIntyre6539d2d2006-06-04 12:31:09 +000087- Patch #1454481: thread stack size is now tunable at runtime for thread
88 enabled builds on Windows and systems with Posix threads support.
89
Neal Norwitz7a5fc282006-05-15 06:48:14 +000090- On Win32, os.listdir now supports arbitrarily-long Unicode path names
91 (up to the system limit of 32K characters).
92
93- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
94 As a result, these functions now raise WindowsError instead of OSError.
95
Tim Peters7a822da2006-05-25 21:50:17 +000096- ``time.clock()`` on Win64 should use the high-performance Windows
97 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
98 Windows platforms).
99
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000100- Calling Tk_Init twice is refused if the first call failed as that
101 may deadlock.
102
Nick Coghlanc649ec52006-05-29 12:43:05 +0000103
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000104Library
105-------
106
Tim Petersd609b1a2006-06-02 23:22:51 +0000107- The functions in the ``pprint`` module now sort dictionaries by key
108 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
109 if and only if its display required more than one line, although that
110 wasn't documented. The new behavior increases predictability; e.g.,
111 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
112
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000113- Patch #1497027: try HTTP digest auth before basic auth in urllib2
114 (thanks for J. J. Lee).
115
Georg Brandl2b330372006-05-28 20:23:12 +0000116- Patch #1496206: improve urllib2 handling of passwords with respect to
117 default HTTP and HTTPS ports.
118
George Yoshidaf3c65de2006-05-28 16:39:09 +0000119- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
120
Bob Ippolito7298f272006-05-23 18:43:47 +0000121- Patch #1281707: speed up gzip.readline.
122
Georg Brandlb89316f2006-05-17 15:51:16 +0000123- Patch #1180296: Two new functions were added to the locale module:
124 format_string() to get the effect of "format % items" but locale-aware,
125 and currency() to format a monetary number with currency sign.
126
Georg Brandle3a25832006-05-17 14:56:04 +0000127- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
128 and several features added, such as speed and geometry control.
129
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000130- Patch #1488881: add support for external file objects in bz2 compressed
131 tarfiles.
132
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000133- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
134 stdout arguments, making it possible to redirect input and output
135 for remote debugging.
136
137- Patch #1484695: Update the tarfile module to version 0.8. This fixes
138 a couple of issues, notably handling of long file names using the
139 GNU LONGNAME extension.
140
141- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
142 new flag when ``name`` is already the name of an option flag.
143
144- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
145 package.
146
147- Patch #1472854: make the rlcompleter.Completer class usable on non-
148 UNIX platforms.
149
150- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000177What's New in Python 2.5 alpha 2?
178=================================
179
180*Release date: 27-APR-2006*
181
182Core and builtins
183-----------------
184
Thomas Heller1b046642006-04-18 18:51:06 +0000185- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
186 by converting these apis from macros into exported functions again:
187
188 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
189 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
190 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
191 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
192 PyRun_String Py_CompileString
193
Martin v. Löwis45294a92006-04-18 06:24:08 +0000194- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
195
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000196- All uses of PyStructSequence_InitType have been changed to initialize
197 the type objects only once, even if the interpreter is initialized
198 multiple times.
199
Neal Norwitz61546162006-04-14 05:20:28 +0000200- Bug #1454485, array.array('u') could crash the interpreter. This was
201 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
202 to unicode when it didn't make sense. 'u#' now requires a unicode string.
203
204- Py_UNICODE is unsigned. It was always documented as unsigned, but
205 due to a bug had a signed value in previous versions.
206
Tim Peters3a5e8b12006-04-11 01:44:07 +0000207- Patch #837242: ``id()`` of any Python object always gives a positive
208 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
209 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000210 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000211 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000212
Tim Peters3a5e8b12006-04-11 01:44:07 +0000213 def __hash__(self):
214 return id(self) # WRONG
215
216 because a hash result must be a (short) Python int but it was always
217 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000218 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000219 was always usable as a hash value before this patch. That's no longer
220 necessarily so.
221
222- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000223 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000224 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000225 #1454844)
226
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000227- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
228 involving generators that have paused outside of any ``try`` or ``with``
229 blocks. (In 2.5a1, a paused generator that was part of a reference
230 cycle could not be garbage collected, regardless of whether it was
231 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000233Extension Modules
234-----------------
235
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000236- Patch #1191065: Fix preprocessor problems on systems where recvfrom
237 is a macro.
238
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000239- Bug #1467952: os.listdir() now correctly raises an error if readdir()
240 fails with an error condition.
241
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000242- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
243
244- Bug #1117761: bsddb.*open() no longer raises an exception when using
245 the cachesize parameter.
246
247- Bug #1149413: bsddb.*open() no longer raises an exception when using
248 a temporary db (file=None) with the 'n' flag to truncate on open.
249
250- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
251 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000252
Armin Rigoa9017c32006-04-19 11:50:27 +0000253- Patch #1062014: AF_UNIX sockets under Linux have a special
254 abstract namespace that is now fully supported.
255
Anthony Baxter51bcb682006-04-05 14:51:42 +0000256Library
257-------
258
Tim Peters711bf302006-04-25 03:31:36 +0000259- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
260 a doctest to be skipped (the code is not run, and the expected output
261 or exception is ignored).
262
Nick Coghlanda2268f2006-04-24 04:37:15 +0000263- Fixed contextlib.nested to cope with exceptions being raised and
264 caught inside exit handlers.
265
Greg Wardab05edc2006-04-23 03:47:58 +0000266- Updated optparse module to Optik 1.5.1 (allow numeric constants in
267 hex, octal, or binary; add ``append_const`` action; keep going if
268 gettext cannot be imported; added ``OptionParser.destroy()`` method;
269 added ``epilog`` for better help generation).
270
Tim Peters21fbd572006-04-21 21:18:10 +0000271- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
272 called from a thread spawned as a side effect of importing a module.
273
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000274- The pydoc module now supports documenting packages contained in
275 .zip or .egg files.
276
277- The pkgutil module now has several new utility functions, such
278 as ``walk_packages()`` to support working with packages that are either
279 in the filesystem or zip files.
280
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000281- The mailbox module can now modify and delete messages from
282 mailboxes, in addition to simply reading them. Thanks to Gregory
283 K. Johnson for writing the code, and to the 2005 Google Summer of
284 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000285
Tim Petersc7605f22006-04-17 21:12:33 +0000286- The ``__del__`` method of class ``local`` in module ``_threading_local``
287 returned before accomplishing any of its intended cleanup.
288
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000289- Patch #790710: Add breakpoint command lists in pdb.
290
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000291- Patch #1063914: Add Tkinter.Misc.clipboard_get().
292
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000293- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
294
Anthony Baxtere29002c2006-04-12 12:07:31 +0000295- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
296 Windows. Bug #1469163.
297
Phillip J. Eby47032112006-04-11 01:07:43 +0000298- The warnings, linecache, inspect, traceback, site, and doctest modules
299 were updated to work correctly with modules imported from zipfiles or
300 via other PEP 302 __loader__ objects.
301
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000302- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis4be4e652006-04-17 19:25:49 +0000315- The Makefile now has a reindent target, which runs reindent.py on
316 the library.
317

323 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000324 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000325 CXX from --with-cxx-main, see description in README.
326
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000327- Patch #1429775: Link extension modules with the shared libpython.
328
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000329- Fixed a libffi build problem on MIPS systems.
330
Tim Peters8931ff12006-05-13 23:28:20 +0000331- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
332 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
333 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000335Tests
336-----
337
Nick Coghlanda2268f2006-04-24 04:37:15 +0000338- test_contextlib now checks contextlib.nested can cope with exceptions
339 being raised and caught inside exit handlers.
340
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000341- test_cmd_line now checks operation of the -m and -c command switches
342
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000343- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
344 it separately and by hand. It also wasn't cleaning up its changes to
345 the current Decimal context.
346
Thomas Woutersabd08882006-04-26 15:53:30 +0000347- regrtest.py now has a -M option to run tests that test the new limits of
348 containers, on 64-bit architectures. Running these tests is only sensible
349 on 64-bit machines with more than two gigabytes of memory. The argument
350 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000358Documentation
359-------------
360
Tim Petersb06d28c2006-05-12 01:57:59 +0000361- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
362
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000363- PEP 343: Added Context Types section to the library reference
364 and attempted to bring other PEP 343 related documentation into
365 line with the implementation and/or python-dev discussions.
366
Tim Peters8dc73d22006-04-24 02:03:16 +0000367- Bug #1337990: clarified that ``doctest`` does not support examples
368 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000371What's New in Python 2.5 alpha 1?
372=================================
373
Anthony Baxterebed3f62006-04-03 15:03:44 +0000374*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000375
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000376Core and builtins
377-----------------
378
Nick Coghlan43832302006-04-23 17:04:07 +0000379- PEP 338: -m command line switch now delegates to runpy.run_module
380 allowing it to support modules in packages and zipfiles
381
Martin v. Löwisc661b882006-04-20 04:54:23 +0000382- On Windows, .DLL is not an accepted file name extension for
383 extension modules anymore; extensions are only found if they
384 end in .PYD.
385
Martin v. Löwisea62d252006-04-03 10:56:49 +0000386- Bug #1421664: sys.stderr.encoding is now set to the same value as
387 sys.stdout.encoding.
388
Neal Norwitz92e212f2006-04-03 04:48:37 +0000389- __import__ accepts keyword arguments.
390
Georg Brandlccadf842006-03-31 18:54:53 +0000391- Patch #1460496: round() now accepts keyword arguments.
392
Anthony Baxter262c00a2006-03-30 10:53:17 +0000393- Fixed bug #1459029 - unicode reprs were double-escaped.
394
Hye-Shik Changd478f342006-03-23 12:32:36 +0000395- Patch #1396919: The system scope threads are reenabled on FreeBSD
396 5.4 and later versions.
397
Neal Norwitze98ccf62006-03-23 05:39:47 +0000398- Bug #1115379: Compiling a Unicode string with an encoding declaration
399 now gives a SyntaxError.
400
Georg Brandlabd1ff82006-03-18 07:59:59 +0000401- Previously, Python code had no easy way to access the contents of a
402 cell object. Now, a ``cell_contents`` attribute has been added
403 (closes patch #1170323).
404
Tim Peterscf79aac2006-03-16 01:14:46 +0000405- Patch #1123430: Python's small-object allocator now returns an arena to
406 the system ``free()`` when all memory within an arena becomes unused
407 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
408 freed. Some applications will see a drop in virtual memory size now,
409 especially long-running applications that, from time to time, temporarily
410 use a large number of small objects. Note that when Python returns an
411 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000412 platform C library will in turn return that memory to the operating system.
413 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000414 appears to be effective at least on Microsoft C and gcc-based systems.
415 Thanks to Evan Jones for hard work and patience.
416
Georg Brandl533ff6f2006-03-08 18:09:27 +0000417- Patch #1434038: property() now uses the getter's docstring if there is
418 no "doc" argument given. This makes it possible to legitimately use
419 property() as a decorator to produce a read-only property.
420
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000421- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
422 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
423 of requiring an int or long in slicing and a few other contexts, enabling
424 other objects (e.g. Numeric Python's integers) to be used as slice indices.
425
Neal Norwitz995acdf2006-03-07 05:01:00 +0000426- Fixed various bugs reported by Coverity's Prevent tool.
427
Brett Cannonbf364092006-03-01 04:25:17 +0000428- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
429 new exception base class, BaseException, which has a new message attribute.
430 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
431 Raising a string exception now raises a DeprecationWarning.
432
Thomas Woutersfb609f42006-02-28 16:37:25 +0000433- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
434 explicitly relative, using 'from .module import name' to mean 'from the same
435 package as this module is in. Imports without dots still default to the
436 old relative-then-absolute, unless 'from __future__ import
437 absolute_import' is used.
438
Brett Cannona7446e32006-02-27 23:39:10 +0000439- Properly check if 'warnings' raises an exception (usually when a filter set
440 to "error" is triggered) when raising a warning for raising string
441 exceptions.
442
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000443- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000444 The name was removed from Include/code.h.
445
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000446- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000447
Guido van Rossum1968ad32006-02-25 22:38:04 +0000448- Patch 1433928:
449 - The copy module now "copies" function objects (as atomic objects).
450 - dict.__getitem__ now looks for a __missing__ hook before raising
451 KeyError.
452
Tim Peters84ef21c2006-02-28 20:39:06 +0000453- PEP 343: with statement implemented. Needs ``from __future__ import
454 with_statement``. Use of 'with' as a variable will generate a warning.
455 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000456 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000457 The following objects have __context__ methods:
458 - The built-in file type.
459 - The thread.LockType type.
460 - The following types defined by the threading module:
461 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
462 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000463
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000464- Fix the encodings package codec search function to only search
465 inside its own package. Fixes problem reported in patch #1433198.
466
467 Note: Codec packages should implement and register their own
468 codec search function. PEP 100 has the details.
469
Tim Peters9ea89d22006-06-04 03:26:02 +0000470- PEP 353: Using ``Py_ssize_t`` as the index type.
471
472- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
473 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
474 now allow Python to make use of memory blocks exceeding 2**32 bytes for
475 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
476 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000477
Neal Norwitzfc76d632006-01-10 06:03:13 +0000478- Patch #1400181, fix unicode string formatting to not use the locale.
479 This is how string objects work. u'%f' could use , instead of .
480 for the decimal point. Now both strings and unicode always use periods.
481
Neal Norwitz671b9e32006-01-09 07:07:12 +0000482- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
483 configure would break checking curses.h.
484
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000485- Bug #959576: The pwd module is now builtin. This allows Python to be
486 built on UNIX platforms without $HOME set.
487
Neal Norwitzc10978f2005-12-19 06:07:16 +0000488- Bug #1072182, fix some potential problems if characters are signed.
489
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000490- Bug #889500, fix line number on SyntaxWarning for global declarations.
491
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000492- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
493
Neal Norwitze7214a12005-12-18 05:03:17 +0000494- Support for converting hex strings to floats no longer works.
495 This was not portable. float('0x3') now raises a ValueError.
496
Barry Warsaw2a38a862005-12-18 01:27:35 +0000497- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000498 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000499 is now displayed in interactive prompt banner.
500
Georg Brandlfa166682005-12-17 21:45:17 +0000501- Implementation of PEP 341 - Unification of try/except and try/finally.
502 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000503 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000504
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000505- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
506 now encodes backslash correctly.
507
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000508- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
509
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000510- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000511 and long longs.
512
Neal Norwitz67715f02005-11-09 06:59:35 +0000513- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000514 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000515 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000516
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000517- Replaced most Unicode charmap codecs with new ones using the
518 new Unicode translate string feature in the builtin charmap
519 codec; the codecs were created from the mapping tables available
520 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
521 encodings now include a mapping for the Apple logo)
522
Tim Peterse3547fd2005-12-16 23:13:57 +0000523- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000524
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000525- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000526
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000527- A new AST parser implementation was completed. The abstract
528 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000529 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000530
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000531- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000532 The following code now raises a SyntaxError: foo(a = i for i in range(10))
533
Neal Norwitz708e51a2005-10-03 04:48:15 +0000534- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
535
Neal Norwitz11bd1192005-10-03 00:54:56 +0000536- SF Bug #887946: fix segfault when redirecting stdin from a directory.
537 Provide a warning when a directory is passed on the command line.
538
Neal Norwitz40d37812005-10-02 01:48:49 +0000539- Fix segfault with invalid coding.
540
541- SF bug #772896: unknown encoding results in MemoryError.
542
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000543- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000544 supported a __len__() method which evaluated to False when the iterator
545 was empty.
546
Guido van Rossum630db602005-09-20 18:49:54 +0000547- On 64-bit platforms, when __len__() returns a value that cannot be
548 represented as a C int, raise OverflowError.
549
Skip Montanarof8948ca2005-09-19 03:54:46 +0000550- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000551 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000552
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000553- SF bug #893549: parsing keyword arguments was broken with a few format
554 codes.
555
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000556- Changes donated by Elemental Security to make it work on AIX 5.3
557 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
558 bug #105470: test_pwd fails on 64bit system (Opteron).
559
Guido van Rossum539c6622005-09-14 17:49:54 +0000560- Changes donated by Elemental Security to make it work on HP-UX 11 on
561 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
562
Georg Brandl4550b8d2005-08-26 06:43:52 +0000563- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000564 (fixes bug #1119418).
565
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000566- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
567
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000568- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
569 exceptions that cause a function to exit.
570
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000571- The implementation of set() and frozenset() was revised to use its
572 own internal data structure. Memory consumption is reduced by 1/3
573 and there are modest speed-ups as well. The API is unchanged.
574
Tim Petersde7990b2005-07-17 23:45:23 +0000575- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
576
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000577- SF bug #1229429: PyObject_CallMethod failed to decrement some
578 reference counts in some error exit cases.
579
Tim Petersecc6e6a2005-07-10 22:30:55 +0000580- SF bug #1185883: Python's small-object memory allocator took over
581 a block managed by the platform C library whenever a realloc specified
582 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000583 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000584 portable way to copy data from the C-managed block into Python's
585 small-object space without risking a memory fault. Python's small-object
586 realloc now leaves such blocks under the control of the platform C
587 realloc.
588
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000589- SF bug #1232517: An overflow error was not detected properly when
590 attempting to convert a large float to an int in os.utime().
591
Raymond Hettinger3296e692005-06-29 23:29:56 +0000592- SF bug #1224347: hex longs now print with lowercase letters just
593 like their int counterparts.
594
Michael W. Hudson188d4362005-06-20 16:52:57 +0000595- SF bug #1163563: the original fix for bug #1010677 ("thread Module
596 Breaks PyGILState_Ensure()") broke badly in the case of multiple
597 interpreter states; back out that fix and do a better job (see
598 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
599 for a longer write-up of the problem).
600
Michael W. Hudsondf888462005-06-03 14:41:55 +0000601- SF patch #1180995: marshal now uses a binary format by default when
602 serializing floats.
603
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000604- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
605 the routines that promise to produce IEEE 754 binary representations
606 of floats now simply copy bytes around.
607
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000608- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
609 278.

Brett Cannonc3647ac2005-04-26 03:45:26 +0000611- patch #1109424: int, long, float, complex, and unicode now check for the
612 proper magic slot for type conversions when subclassed. Previously the
613 magic slot was ignored during conversion. Semantics now match the way
614 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000615 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000616 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000617 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000618
Barry Warsawc8d907c2005-04-19 23:43:40 +0000619- Descriptors defined in C with a PyGetSetDef structure, where the setter is
620 NULL, now raise an AttributeError when attempting to set or delete the
621 attribute. Previously a TypeError was raised, but this was inconsistent
622 with the equivalent pure-Python implementation.
623
Michael W. Hudson774479c2005-04-18 08:46:17 +0000624- It is now safe to call PyGILState_Release() before
625 PyEval_InitThreads() (note that if there is reason to believe there
626 are multiple threads around you still must call PyEval_InitThreads()
627 before using the Python API; this fix is for extension modules that
628 have no way of knowing if Python is multi-threaded yet).
629
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000630- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
631 disabled caused a crash.
632
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000633- Bug #1165306: instancemethod_new allowed the creation of a method
634 with im_class == im_self == NULL, which caused a crash when called.
635
Tim Petersecc6e6a2005-07-10 22:30:55 +0000636- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000637 fixes the crash seen in bug #1165761
638
Raymond Hettinger96229b12005-03-11 06:49:40 +0000639- Added two new builtins, any() and all().
640
Brett Cannon409d8f22005-03-05 06:47:57 +0000641- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000642 (e.g., ``class C(): pass`` is no longer a syntax error).
643 Patch #1176012 added support to the 'parser' module and 'compiler' package
644 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000645
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000646- Patch #1115086: Support PY_LONGLONG in structmember.
647
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000648- Bug #1155938: new style classes did not check that __init__() was
649 returning None.
650
Tim Petersecc6e6a2005-07-10 22:30:55 +0000651- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000652 ('\') with a specific error message.
653
Martin v. Löwisff232d72005-03-03 09:24:38 +0000654- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
655
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000656- Bug #1124295: the __name__ attribute of file objects was
657 inadvertently made inaccessible in restricted mode.
658
Tim Petersecc6e6a2005-07-10 22:30:55 +0000659- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000660 an ferror() call.
661
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000662- min() and max() now support key= arguments with the same meaning as in
663 list.sort().
664
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000665- The peephole optimizer now performs simple constant folding in expressions:
666 (2+3) --> (5).
667
Raymond Hettingera422c342005-01-11 03:03:27 +0000668- set and frozenset objects can now be marshalled. SF #1098985.
669
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000670- Bug #1077106: Poor argument checking could cause memory corruption
671 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000672
Jeremy Hyltonab630502005-02-04 18:44:06 +0000673- The parser did not complain about future statements in illegal
674 positions. It once again reports a syntax error if a future
675 statement occurs after anything other than a doc string.
676
Neil Schemenauercf52c072005-08-12 17:34:58 +0000677- Change the %s format specifier for str objects so that it returns a
678 unicode instance if the argument is not an instance of basestring and
679 calling __str__ on the argument returns a unicode instance.
680
Tim Petersf4e69282006-02-27 17:15:31 +0000681- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
682 current thread state when the auto-GIL-state machinery knows about
683 it (since the thread state is being deleted, continuing to remember it
684 can't help, but can hurt if another thread happens to get created with
685 the same thread id).

715 for applications that require this specific version (such as IDNA).
716
Neal Norwitzb62c4332006-03-04 18:35:47 +0000717- The timing module is no longer built by default. It was deprecated

889 in attribute values.
890
Anthony Baxterc51ee692006-04-01 00:57:31 +0000891- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000892 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000893 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000894 module will not be built.
895
Tim Petersc17976e2006-04-01 00:26:53 +0000896- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
897 aren't officially supported here, and trying to use them will probably
898 raise an exception some day. But dicts have been allowed, and "mostly
899 worked", so support for them won't go away without warning.
900
Georg Brandl338ef7d2006-03-31 18:42:16 +0000901- Bug #1445068: getpass.getpass() can now be given an explicit stream
902 argument to specify where to write the prompt.
903
Georg Brandl22ec80b2006-03-31 18:25:44 +0000904- Patch #1462313, bug #1443328: the pickle modules now can handle classes

910 key to be used for signing the uploaded code.
911
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000912- Queue.Queue objects now support .task_done() and .join() methods
913 to make it easier to monitor when daemon threads have completed
914 processing all enqueued tasks. Patch #1455676.
915
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000916- popen2.Popen objects now preserve the command in a .cmd attribute.
917
Thomas Hellerc61c0492006-03-22 10:09:27 +0000918- Added the ctypes ffi package.
919
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000920- email 4.0 package now integrated. This is largely the same as the email 3.0
921 package that was included in Python 2.3, except that PEP 8 module names are
922 now used (e.g. mail.message instead of email.Message). The MIME classes
923 have been moved to a subpackage (e.g. email.mime.text instead of
924 email.MIMEText). The old names are still supported for now. Several
925 deprecated Message methods have been removed and lots of bugs have been
926 fixed. More details can be found in the email package documentation.
927
Walter Dörwald40108c92006-03-27 08:15:44 +0000928- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
929 (a subclass of tuple) that provides incremental decoders and encoders
930 (a way to use stateful codecs without the stream API). Python functions
931 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
932 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
933 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000934
Walter Dörwald067db482006-03-15 22:17:27 +0000935- Patch #1359365: Calling next() on a closed StringIO.String object raises
936 a ValueError instead of a StopIteration now (like file and cString.String do).
937 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
938 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000939
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000940- A regrtest option -w was added to re-run failed tests in verbose mode.

943 interpreter to exit.
944
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000945- The function get_count() has been added to the gc module, and gc.collect()
946 grew an optional 'generation' argument.
947
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000948- A library msilib to generate Windows Installer files, and a distutils
949 command bdist_msi have been added.

1008 LoadError as documented, instead of IOError. For compatibility,
1009 LoadError subclasses IOError.
1010
Brett Cannon3cbd0382005-12-16 22:49:23 +00001011- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001012 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1013 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1014 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1015 Ronald L. Rivest offered this advice for Python:
1016
1017 "The consensus of researchers in this area (at least as
1018 expressed at the NIST Hash Function Workshop 10/31/05),
1019 is that SHA-256 is a good choice for the time being, but
1020 that research should continue, and other alternatives may
1021 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001022
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001023- Added a subset of Fredrik Lundh's ElementTree package. Available

1094 parameter, but uses the usual "kwargs=None".
1095

1116 Bug #1224621.
1117
Raymond Hettinger68c04532005-06-10 11:05:19 +00001118- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001119 roundtrip from lexed tokens back to Python source code. In addition,

1131 class at all.
1132
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001133- distutils.commands.upload was added to support uploading distribution

1177
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001178- Patch #1049151: xdrlib now unpacks booleans as True or False.
1179
Raymond Hettingerbab41432005-02-05 01:31:19 +00001180- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1181
Guido van Rossumd0641422005-02-03 15:01:24 +00001182- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1183 disables recursive traversal through instance attributes, which can
1184 be exploited in various ways.
1185
Tim Peterse3547fd2005-12-16 23:13:57 +00001186- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001187 flags on the HTTP listening socket.
1188
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001189- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1190 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1191
Tim Peterse3547fd2005-12-16 23:13:57 +00001192- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001193 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1194

1196
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001197- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1198
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001199- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1200
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001201- Enhancements to the csv module:
1202
1203 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001204 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001205 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001206 + Dialect parameter parsing has been re-implemented to improve error
1207 reporting.
1208 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1209 dictates.
1210 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001211 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001212 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001213 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1214 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001215 + reader now allows \r characters to be quoted (previously it only allowed
1216 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001217 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001218 + Dialect classes passed to the module are no longer instantiated by
1219 the module before being parsed (the former validation scheme required
1220 this, but the mechanism was unreliable).
1221 + The dialect registry now contains instances of the internal
1222 C-coded dialect type, rather than references to python objects.
1223 + the internal c-coded dialect type is now immutable.
1224 + register_dialect now accepts the same keyword dialect specifications
1225 as the reader and writer, allowing the user to register dialects
1226 without first creating a dialect class.
1227 + a configurable limit to the size of parsed fields has been added -
1228 previously, an unmatched quote character could result in the entire
1229 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001230 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001231 the parser field size limit (returning the former limit). The initial
1232 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001233 + A line_num attribute has been added to the reader object, which tracks
1234 the number of lines read from the source iterator. This is not
1235 the same as the number of records returned, as records can span
1236 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001237 + reader and writer objects were not being registered with the cyclic-GC.
1238 This has been fixed.
1239
Brett Cannone6539c42005-01-08 02:43:53 +00001240- _DummyThread objects in the threading module now delete self.__block that is
1241 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1242 lock primitives tend to be limited in number and thus should not be wasted on
1243 a _DummyThread object. Fixes bug #1089632.
1244
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001245- The imghdr module now detects Exif files.
1246
Raymond Hettinger6065d322004-12-20 23:51:53 +00001247- StringIO.truncate() now correctly adjusts the size attribute.
1248 (Bug #951915).
1249
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001250- locale.py now uses an updated locale alias table (built using
1251 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1252 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001253 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001254
Raymond Hettinger3557f422004-12-07 12:02:02 +00001255- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1256
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001257- the pickle module no longer accepts the deprecated None option in the
1258 args tuple returned by __reduce__().
1259
Brett Cannon84667c02004-12-07 03:25:18 +00001260- optparse now optionally imports gettext. This allows its use in setup.py.
1261
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001262- the pickle module no longer uses the deprecated bin parameter.
1263
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001264- the shelve module no longer uses the deprecated binary parameter.
1265
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001266- the pstats module no longer uses the deprecated ignore() method.
1267
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001268- the filecmp module no longer uses the deprecated use_statcache argument.
1269
Raymond Hettinger664347b2004-12-04 21:21:53 +00001270- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1271 extended or overridden by subclasses. Formerly, the subclassed method would
1272 be ignored by the rest of the module. (Bug #1078905).
1273
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001274- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001275 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001276
Walter Dörwald36733692004-12-22 12:50:50 +00001277- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1278 once when a size argument is given. This prevents a buffer overflow in the
1279 tokenizer with very long source lines.
1280
Barry Warsaw538561e2006-01-01 21:48:54 +00001281- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1282 immediately after creating the object, without any intervening
1283 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001284
Skip Montanaro05885812005-01-16 20:48:27 +00001285- The reconvert.quote function can now emit triple-quoted strings. The
1286 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001287
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001288- ``UserString.MutableString`` now supports negative indices in
1289 ``__setitem__`` and ``__delitem__``
1290
Greg Ward40407942005-03-05 02:53:17 +00001291- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1292 correctly.
1293
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001294- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1295 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1296 character even if the user has passed a size parameter to get a proper
1297 line ending. Remove the special handling of a "\r\n" that has been split
1298 between two lines.
1299
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001300- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1301 about illegal code points. The codec now supports PEP 293 style error
1302 handlers.
1303
Walter Dörwald78a78b02005-09-01 12:04:29 +00001304- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001305 from the input stream, so that the output is a byte string in the correct
1306 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001307
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001308- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1309 considering it exactly like a '*'.
1310
Walter Dörwald007f8df2005-10-09 19:42:27 +00001311- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1312 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001313
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001314- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1315
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001316- Patch #1413711: Certain patterns of differences were making difflib
1317 touch the recursion limit.
1318
Walter Dörwald58917a62006-03-31 15:26:22 +00001319- Bug #947906: An object oriented interface has been added to the calendar
1320 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001321 called as a script (e.g. via ``python -mcalendar``). Localized month and
1322 weekday names can be ouput (even if an exotic encoding is used) using
1323 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001324
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001325Build
1326-----
1327
Neal Norwitz602d3392006-03-31 08:21:40 +00001328- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1329 by using -mieee gcc option.
1330
Martin v. Löwis86d66262006-02-17 08:40:11 +00001331- Patch #1432345: Make python compile on DragonFly.
1332
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001333- Build support for Win64-AMD64 was added.
1334
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001335- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1336
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001337- Patch #881820: look for openpty and forkpty also in libbsd.
1338
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001339- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1340 The zlib module is now builtin on Windows.
1341
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001342- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1343
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001344- Bug #1189330: configure did not correctly determine the necessary
1345 value of LINKCC if python was built with GCC 4.0.
1346
Trent Mick8321b422005-07-26 02:29:21 +00001347- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1348 vulnerability in zlib 1.2.1 and 1.2.2.
1349
Brett Cannon08cd5982005-04-24 22:26:38 +00001350- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1351 flags that change binary compatibility. Changes were also made to
1352 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001353 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001354
Bob Ippolitoed233462005-03-29 13:47:59 +00001355- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1356 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1357 no longer exists). This configure patch makes things right.
1358
Martin v. Löwise2713be2005-03-08 15:03:08 +00001359- Bug #1158607: Build with --disable-unicode again.
1360
Brett Cannon46d96232005-02-16 00:07:19 +00001361- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1362 defined. Discovered as a result of not being able to build on OS X.
1363
Brett Cannon516592f2004-12-07 00:42:59 +00001364- setup.py now uses the directories specified in LDFLAGS using the -L option
1365 and in CPPFLAGS using the -I option for adding library and include
1366 directories, respectively, for compiling extension modules against. This has
1367 led to the core being compiled using the values in CPPFLAGS. It also removes
1368 the need for the special-casing of both DarwinPorts and Fink for darwin since
1369 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1370 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1371 Fink, ``-I/opt/local/include`` for DarwinPorts).
1372
Brett Cannon43802422005-02-10 20:48:03 +00001373- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1374 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1375 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1376 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001378C API
1379-----
1380
Tim Petersc9d78aa2006-03-26 23:27:58 +00001381- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1382 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1383 is obtained via the ``PyObject_`` family, it must be released via the
1384 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1385 always been officially true, but when Python's small-object allocator was
1386 introduced, an attempt was made to cater to a few extension modules
1387 discovered at the time that obtained memory via ``PyObject_New`` but
1388 released it via ``PyMem_DEL``. It's years later, and if such code still
1389 exists it will fail now (probably with segfaults, but calling wrong
1390 low-level memory management functions can yield many symptoms).
1391
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001392- Added a C API for set and frozenset objects.
1393
Raymond Hettinger66517482004-12-03 11:45:13 +00001394- Removed PyRange_New().
1395
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001396- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1397 mapping argument now. This string is used as a mapping table. Byte values
1398 greater than the length of the string and 0xFFFE are treated as undefined
1399 mappings.
