Nick Coghlanc649ec52006-05-29 12:43:05 +00007What's New in Python 2.5 beta 1?
Anthony Baxter51bcb682006-04-05 14:51:42 +00008=================================

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 Brandlddbaa662006-06-04 21:56:52 +000015- Patch #1346214: Statements like "if 0: suite" are now again optimized
16 away like they were in Python 2.4.
17
Georg Brandlb7c8f542006-05-27 12:30:25 +000018- Builtin exceptions are now full-blown new-style classes instead of
19 instances pretending to be classes, which speeds up exception handling
20 by about 80% in comparison to 2.5a2.
21
Martin v. Löwisd004fc82006-05-27 08:36:52 +000022- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
23 Unicode 4.1.
24
Georg Brandlf4ef1162006-05-26 18:03:31 +000025- Patch #921466: sys.path_importer_cache is now used to cache valid and
26 invalid file paths for the built-in import machinery which leads to
27 fewer open calls on startup.
28
Tim Peters696cf432006-05-24 21:10:40 +000029- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
30 of-2 bases. The largest speedup is for inputs with about 1000 decimal
31 digits. Conversion from non-power-of-2 bases remains quadratic-time in
32 the number of input digits (it was and remains linear-time for bases
33 2, 4, 8, 16 and 32).
34
Tim Petersb713ec22006-05-23 18:45:30 +000035- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
36 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
37 an integer close to ``sys.maxint``. This was repaired by patch
38 #1335972, which also gives a nice speedup.
39
Richard Jonescebbefc2006-05-23 18:28:17 +000040- Patch #1337051: reduced size of frame objects.
41
42- PyErr_NewException now accepts a tuple of base classes as its
43 "base" parameter.
44
Richard Jones7c88dcc2006-05-23 10:37:38 +000045- Patch #876206: function call speedup by retaining allocated frame
46 objects.
47
Georg Brandl7b90e162006-05-18 07:01:27 +000048- Bug #1462152: file() now checks more thoroughly for invalid mode
49 strings and removes a possible "U" before passing the mode to the
50 C library function.
51
Neal Norwitz1004a532006-05-15 07:17:23 +000052- Patch #1488312, Fix memory alignment problem on SPARC in unicode
53
Neal Norwitz373f0a72006-05-15 07:04:36 +000054- Bug #1487966: Fix SystemError with conditional expression in assignment
55
Martin v. Löwis879768d2006-05-11 13:28:43 +000056- WindowsError now has two error code attributes: errno, which carries
57 the error values from errno.h, and winerror, which carries the error
58 values from winerror.h. Previous versions put the winerror.h values
59 (from GetLastError()) into the errno attribute.
60
Martin v. Löwis77736712006-05-04 05:51:03 +000061- Patch #1475845: Raise IndentationError for unexpected indent.
62
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000063- Patch #1479181: split open() and file() from being aliases for each other.
64
Tim Peters44bd9862006-06-01 13:49:23 +000065- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
66 methods were always silently ignored by dictionaries when comparing keys.
67 They are now passed through (except when using the C API function
68 ``PyDict_GetItem()``, whose semantics did not change).
69
70- Bug #1456209: In some obscure cases it was possible for a class with a
71 custom ``__eq__()`` method to confuse dict internals when class instances
72 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
73 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +000075Extension Modules
76-----------------
77
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +000078- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
79
Nick Coghlanc649ec52006-05-29 12:43:05 +000080- Patch #1478788 (modified version): The functional extension module has
81 been renamed to _functools and a functools Python wrapper module added.
82 This provides a home for additional function related utilities that are
83 not specifically about functional programming. See PEP 309.
84
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000085- Patch #1493701: performance enhancements for struct module.
86
Georg Brandl378d5922006-05-17 14:26:50 +000087- Patch #1490224: time.altzone is now set correctly on Cygwin.
88
Georg Brandl8d3342b2006-05-16 07:38:27 +000089- Patch #1435422: zlib's compress and decompress objects now have a
90 copy() method.
91
Neal Norwitz7a5fc282006-05-15 06:48:14 +000092- On Win32, os.listdir now supports arbitrarily-long Unicode path names
93 (up to the system limit of 32K characters).
94
95- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
96 As a result, these functions now raise WindowsError instead of OSError.
97
Tim Peters7a822da2006-05-25 21:50:17 +000098- ``time.clock()`` on Win64 should use the high-performance Windows
99 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
100 Windows platforms).
101
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000102- Calling Tk_Init twice is refused if the first call failed as that
103 may deadlock.
104
Nick Coghlanc649ec52006-05-29 12:43:05 +0000105
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000106Library
107-------
108
Tim Petersbf0400a2006-06-05 01:43:03 +0000109- The optional ``is_private`` argument to ``doctest.testmod()``, deprecated
110 in 2.4, was removed.
111
Martin v. Löwis3f767792006-06-04 19:36:28 +0000112- Patch #1359618: Speed up charmap encoder by using a trie structure
113 for lookup.
114
Tim Petersd609b1a2006-06-02 23:22:51 +0000115- The functions in the ``pprint`` module now sort dictionaries by key
116 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
117 if and only if its display required more than one line, although that
118 wasn't documented. The new behavior increases predictability; e.g.,
119 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
120
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000121- Patch #1497027: try HTTP digest auth before basic auth in urllib2
122 (thanks for J. J. Lee).
123
Georg Brandl2b330372006-05-28 20:23:12 +0000124- Patch #1496206: improve urllib2 handling of passwords with respect to
125 default HTTP and HTTPS ports.
126
George Yoshidaf3c65de2006-05-28 16:39:09 +0000127- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
128
Bob Ippolito7298f272006-05-23 18:43:47 +0000129- Patch #1281707: speed up gzip.readline.
130
Georg Brandlb89316f2006-05-17 15:51:16 +0000131- Patch #1180296: Two new functions were added to the locale module:
132 format_string() to get the effect of "format % items" but locale-aware,
133 and currency() to format a monetary number with currency sign.
134
Georg Brandle3a25832006-05-17 14:56:04 +0000135- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
136 and several features added, such as speed and geometry control.
137
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000138- Patch #1488881: add support for external file objects in bz2 compressed
139 tarfiles.
140
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000141- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
142 stdout arguments, making it possible to redirect input and output
143 for remote debugging.
144
145- Patch #1484695: Update the tarfile module to version 0.8. This fixes
146 a couple of issues, notably handling of long file names using the
147 GNU LONGNAME extension.
148
149- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
150 new flag when ``name`` is already the name of an option flag.
151
152- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
153 package.
154
155- Patch #1472854: make the rlcompleter.Completer class usable on non-
156 UNIX platforms.
157
158- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000185What's New in Python 2.5 alpha 2?
186=================================
187
188*Release date: 27-APR-2006*
189
190Core and builtins
191-----------------
192
Thomas Heller1b046642006-04-18 18:51:06 +0000193- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
194 by converting these apis from macros into exported functions again:
195
196 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
197 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
198 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
199 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
200 PyRun_String Py_CompileString
201
Martin v. Löwis45294a92006-04-18 06:24:08 +0000202- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
203
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000204- All uses of PyStructSequence_InitType have been changed to initialize
205 the type objects only once, even if the interpreter is initialized
206 multiple times.
207
Neal Norwitz61546162006-04-14 05:20:28 +0000208- Bug #1454485, array.array('u') could crash the interpreter. This was
209 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
210 to unicode when it didn't make sense. 'u#' now requires a unicode string.
211
212- Py_UNICODE is unsigned. It was always documented as unsigned, but
213 due to a bug had a signed value in previous versions.
214
Tim Peters3a5e8b12006-04-11 01:44:07 +0000215- Patch #837242: ``id()`` of any Python object always gives a positive
216 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
217 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000218 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000219 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000220
Tim Peters3a5e8b12006-04-11 01:44:07 +0000221 def __hash__(self):
222 return id(self) # WRONG
223
224 because a hash result must be a (short) Python int but it was always
225 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000226 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000227 was always usable as a hash value before this patch. That's no longer
228 necessarily so.
229
230- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000231 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000232 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000233 #1454844)
234
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000235- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
236 involving generators that have paused outside of any ``try`` or ``with``
237 blocks. (In 2.5a1, a paused generator that was part of a reference
238 cycle could not be garbage collected, regardless of whether it was
239 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000241Extension Modules
242-----------------
243
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000244- Patch #1191065: Fix preprocessor problems on systems where recvfrom
245 is a macro.
246
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000247- Bug #1467952: os.listdir() now correctly raises an error if readdir()
248 fails with an error condition.
249
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000250- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
251
252- Bug #1117761: bsddb.*open() no longer raises an exception when using
253 the cachesize parameter.
254
255- Bug #1149413: bsddb.*open() no longer raises an exception when using
256 a temporary db (file=None) with the 'n' flag to truncate on open.
257
258- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
259 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000260
Armin Rigoa9017c32006-04-19 11:50:27 +0000261- Patch #1062014: AF_UNIX sockets under Linux have a special
262 abstract namespace that is now fully supported.
263

265-------
266
Tim Peters711bf302006-04-25 03:31:36 +0000267- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
268 a doctest to be skipped (the code is not run, and the expected output
269 or exception is ignored).
270
Nick Coghlanda2268f2006-04-24 04:37:15 +0000271- Fixed contextlib.nested to cope with exceptions being raised and
272 caught inside exit handlers.
273
Greg Wardab05edc2006-04-23 03:47:58 +0000274- Updated optparse module to Optik 1.5.1 (allow numeric constants in
275 hex, octal, or binary; add ``append_const`` action; keep going if
276 gettext cannot be imported; added ``OptionParser.destroy()`` method;
277 added ``epilog`` for better help generation).
278
Tim Peters21fbd572006-04-21 21:18:10 +0000279- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
280 called from a thread spawned as a side effect of importing a module.
281
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000282- The pydoc module now supports documenting packages contained in
283 .zip or .egg files.
284
285- The pkgutil module now has several new utility functions, such
286 as ``walk_packages()`` to support working with packages that are either
287 in the filesystem or zip files.
288
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000289- The mailbox module can now modify and delete messages from
290 mailboxes, in addition to simply reading them. Thanks to Gregory
291 K. Johnson for writing the code, and to the 2005 Google Summer of
292 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000293
Tim Petersc7605f22006-04-17 21:12:33 +0000294- The ``__del__`` method of class ``local`` in module ``_threading_local``
295 returned before accomplishing any of its intended cleanup.
296
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000297- Patch #790710: Add breakpoint command lists in pdb.
298
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000299- Patch #1063914: Add Tkinter.Misc.clipboard_get().
300
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000301- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
302
Anthony Baxtere29002c2006-04-12 12:07:31 +0000303- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
304 Windows. Bug #1469163.
305
Phillip J. Eby47032112006-04-11 01:07:43 +0000306- The warnings, linecache, inspect, traceback, site, and doctest modules
307 were updated to work correctly with modules imported from zipfiles or
308 via other PEP 302 __loader__ objects.
309
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000310- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis4be4e652006-04-17 19:25:49 +0000323- The Makefile now has a reindent target, which runs reindent.py on
324 the library.
325

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000330- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
331 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000332 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000333 CXX from --with-cxx-main, see description in README.
334
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000335- Patch #1429775: Link extension modules with the shared libpython.
336
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000337- Fixed a libffi build problem on MIPS systems.
338
Tim Peters8931ff12006-05-13 23:28:20 +0000339- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
340 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
341 and "%zu" for unsigned integers of type ``size_t``.
342
Anthony Baxter51bcb682006-04-05 14:51:42 +0000343Tests
344-----
345
Nick Coghlanda2268f2006-04-24 04:37:15 +0000346- test_contextlib now checks contextlib.nested can cope with exceptions
347 being raised and caught inside exit handlers.
348
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000349- test_cmd_line now checks operation of the -m and -c command switches
350
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000351- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
352 it separately and by hand. It also wasn't cleaning up its changes to
353 the current Decimal context.
354
Thomas Woutersabd08882006-04-26 15:53:30 +0000355- regrtest.py now has a -M option to run tests that test the new limits of
356 containers, on 64-bit architectures. Running these tests is only sensible
357 on 64-bit machines with more than two gigabytes of memory. The argument
358 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000366Documentation
367-------------
368
Tim Petersb06d28c2006-05-12 01:57:59 +0000369- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
370
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000371- PEP 343: Added Context Types section to the library reference
372 and attempted to bring other PEP 343 related documentation into
373 line with the implementation and/or python-dev discussions.
374
Tim Peters8dc73d22006-04-24 02:03:16 +0000375- Bug #1337990: clarified that ``doctest`` does not support examples
376 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000379What's New in Python 2.5 alpha 1?
380=================================
381
Anthony Baxterebed3f62006-04-03 15:03:44 +0000382*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000383
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000384Core and builtins
385-----------------
386
Nick Coghlan43832302006-04-23 17:04:07 +0000387- PEP 338: -m command line switch now delegates to runpy.run_module
388 allowing it to support modules in packages and zipfiles
389
Martin v. Löwisc661b882006-04-20 04:54:23 +0000390- On Windows, .DLL is not an accepted file name extension for
391 extension modules anymore; extensions are only found if they
392 end in .PYD.
393
Martin v. Löwisea62d252006-04-03 10:56:49 +0000394- Bug #1421664: sys.stderr.encoding is now set to the same value as
395 sys.stdout.encoding.
396
Neal Norwitz92e212f2006-04-03 04:48:37 +0000397- __import__ accepts keyword arguments.
398
Georg Brandlccadf842006-03-31 18:54:53 +0000399- Patch #1460496: round() now accepts keyword arguments.
400
Anthony Baxter262c00a2006-03-30 10:53:17 +0000401- Fixed bug #1459029 - unicode reprs were double-escaped.
402
Hye-Shik Changd478f342006-03-23 12:32:36 +0000403- Patch #1396919: The system scope threads are reenabled on FreeBSD
404 5.4 and later versions.
405
Neal Norwitze98ccf62006-03-23 05:39:47 +0000406- Bug #1115379: Compiling a Unicode string with an encoding declaration
407 now gives a SyntaxError.
408
Georg Brandlabd1ff82006-03-18 07:59:59 +0000409- Previously, Python code had no easy way to access the contents of a
410 cell object. Now, a ``cell_contents`` attribute has been added
411 (closes patch #1170323).
412
Tim Peterscf79aac2006-03-16 01:14:46 +0000413- Patch #1123430: Python's small-object allocator now returns an arena to
414 the system ``free()`` when all memory within an arena becomes unused
415 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
416 freed. Some applications will see a drop in virtual memory size now,
417 especially long-running applications that, from time to time, temporarily
418 use a large number of small objects. Note that when Python returns an
419 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000420 platform C library will in turn return that memory to the operating system.
421 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000422 appears to be effective at least on Microsoft C and gcc-based systems.
423 Thanks to Evan Jones for hard work and patience.
424
Georg Brandl533ff6f2006-03-08 18:09:27 +0000425- Patch #1434038: property() now uses the getter's docstring if there is
426 no "doc" argument given. This makes it possible to legitimately use
427 property() as a decorator to produce a read-only property.
428
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000429- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
430 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
431 of requiring an int or long in slicing and a few other contexts, enabling
432 other objects (e.g. Numeric Python's integers) to be used as slice indices.
433
Neal Norwitz995acdf2006-03-07 05:01:00 +0000434- Fixed various bugs reported by Coverity's Prevent tool.
435
Brett Cannonbf364092006-03-01 04:25:17 +0000436- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
437 new exception base class, BaseException, which has a new message attribute.
438 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
439 Raising a string exception now raises a DeprecationWarning.
440
Thomas Woutersfb609f42006-02-28 16:37:25 +0000441- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
442 explicitly relative, using 'from .module import name' to mean 'from the same
443 package as this module is in. Imports without dots still default to the
444 old relative-then-absolute, unless 'from __future__ import
445 absolute_import' is used.
446
Brett Cannona7446e32006-02-27 23:39:10 +0000447- Properly check if 'warnings' raises an exception (usually when a filter set
448 to "error" is triggered) when raising a warning for raising string
449 exceptions.
450
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000451- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000452 The name was removed from Include/code.h.
453
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000454- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000455
Guido van Rossum1968ad32006-02-25 22:38:04 +0000456- Patch 1433928:
457 - The copy module now "copies" function objects (as atomic objects).
458 - dict.__getitem__ now looks for a __missing__ hook before raising
459 KeyError.
460
Tim Peters84ef21c2006-02-28 20:39:06 +0000461- PEP 343: with statement implemented. Needs ``from __future__ import
462 with_statement``. Use of 'with' as a variable will generate a warning.
463 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000464 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000465 The following objects have __context__ methods:
466 - The built-in file type.
467 - The thread.LockType type.
468 - The following types defined by the threading module:
469 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
470 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000471
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000472- Fix the encodings package codec search function to only search
473 inside its own package. Fixes problem reported in patch #1433198.
474
475 Note: Codec packages should implement and register their own
476 codec search function. PEP 100 has the details.
477
Tim Peters9ea89d22006-06-04 03:26:02 +0000478- PEP 353: Using ``Py_ssize_t`` as the index type.
479
480- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
481 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
482 now allow Python to make use of memory blocks exceeding 2**32 bytes for
483 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
484 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000485
Neal Norwitzfc76d632006-01-10 06:03:13 +0000486- Patch #1400181, fix unicode string formatting to not use the locale.
487 This is how string objects work. u'%f' could use , instead of .
488 for the decimal point. Now both strings and unicode always use periods.
489
Neal Norwitz671b9e32006-01-09 07:07:12 +0000490- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
491 configure would break checking curses.h.
492
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000493- Bug #959576: The pwd module is now builtin. This allows Python to be
494 built on UNIX platforms without $HOME set.
495
Neal Norwitzc10978f2005-12-19 06:07:16 +0000496- Bug #1072182, fix some potential problems if characters are signed.
497
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000498- Bug #889500, fix line number on SyntaxWarning for global declarations.
499
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000500- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
501
Neal Norwitze7214a12005-12-18 05:03:17 +0000502- Support for converting hex strings to floats no longer works.
503 This was not portable. float('0x3') now raises a ValueError.
504
Barry Warsaw2a38a862005-12-18 01:27:35 +0000505- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000506 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000507 is now displayed in interactive prompt banner.
508
Georg Brandlfa166682005-12-17 21:45:17 +0000509- Implementation of PEP 341 - Unification of try/except and try/finally.
510 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000511 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000512
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000513- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
514 now encodes backslash correctly.
515
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000516- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
517
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000518- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000519 and long longs.
520
Neal Norwitz67715f02005-11-09 06:59:35 +0000521- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000522 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000523 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000524
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000525- Replaced most Unicode charmap codecs with new ones using the
526 new Unicode translate string feature in the builtin charmap
527 codec; the codecs were created from the mapping tables available
528 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
529 encodings now include a mapping for the Apple logo)
530
Tim Peterse3547fd2005-12-16 23:13:57 +0000531- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000532
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000533- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000534
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000535- A new AST parser implementation was completed. The abstract
536 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000537 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000538
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000539- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000540 The following code now raises a SyntaxError: foo(a = i for i in range(10))
541
Neal Norwitz708e51a2005-10-03 04:48:15 +0000542- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
543
Neal Norwitz11bd1192005-10-03 00:54:56 +0000544- SF Bug #887946: fix segfault when redirecting stdin from a directory.
545 Provide a warning when a directory is passed on the command line.
546
Neal Norwitz40d37812005-10-02 01:48:49 +0000547- Fix segfault with invalid coding.
548
549- SF bug #772896: unknown encoding results in MemoryError.
550
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000551- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000552 supported a __len__() method which evaluated to False when the iterator
553 was empty.
554
Guido van Rossum630db602005-09-20 18:49:54 +0000555- On 64-bit platforms, when __len__() returns a value that cannot be
556 represented as a C int, raise OverflowError.
557
Skip Montanarof8948ca2005-09-19 03:54:46 +0000558- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000559 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000560
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000561- SF bug #893549: parsing keyword arguments was broken with a few format
562 codes.
563
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000564- Changes donated by Elemental Security to make it work on AIX 5.3
565 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
566 bug #105470: test_pwd fails on 64bit system (Opteron).
567
Guido van Rossum539c6622005-09-14 17:49:54 +0000568- Changes donated by Elemental Security to make it work on HP-UX 11 on
569 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
570
Georg Brandl4550b8d2005-08-26 06:43:52 +0000571- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000572 (fixes bug #1119418).
573
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000574- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
575
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000576- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
577 exceptions that cause a function to exit.
578
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000579- The implementation of set() and frozenset() was revised to use its
580 own internal data structure. Memory consumption is reduced by 1/3
581 and there are modest speed-ups as well. The API is unchanged.
582
Tim Petersde7990b2005-07-17 23:45:23 +0000583- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
584
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000585- SF bug #1229429: PyObject_CallMethod failed to decrement some
586 reference counts in some error exit cases.
587
Tim Petersecc6e6a2005-07-10 22:30:55 +0000588- SF bug #1185883: Python's small-object memory allocator took over
589 a block managed by the platform C library whenever a realloc specified
590 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000591 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000592 portable way to copy data from the C-managed block into Python's
593 small-object space without risking a memory fault. Python's small-object
594 realloc now leaves such blocks under the control of the platform C
595 realloc.
596
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000597- SF bug #1232517: An overflow error was not detected properly when
598 attempting to convert a large float to an int in os.utime().
599
Raymond Hettinger3296e692005-06-29 23:29:56 +0000600- SF bug #1224347: hex longs now print with lowercase letters just
601 like their int counterparts.
602
Michael W. Hudson188d4362005-06-20 16:52:57 +0000603- SF bug #1163563: the original fix for bug #1010677 ("thread Module
604 Breaks PyGILState_Ensure()") broke badly in the case of multiple
605 interpreter states; back out that fix and do a better job (see
606 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
607 for a longer write-up of the problem).
608
Michael W. Hudsondf888462005-06-03 14:41:55 +0000609- SF patch #1180995: marshal now uses a binary format by default when
610 serializing floats.
611
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000612- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
613 the routines that promise to produce IEEE 754 binary representations
614 of floats now simply copy bytes around.
615
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000616- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
617 278.
618
Brett Cannonc3647ac2005-04-26 03:45:26 +0000619- patch #1109424: int, long, float, complex, and unicode now check for the
620 proper magic slot for type conversions when subclassed. Previously the
621 magic slot was ignored during conversion. Semantics now match the way
622 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000623 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000624 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000625 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000626
Barry Warsawc8d907c2005-04-19 23:43:40 +0000627- Descriptors defined in C with a PyGetSetDef structure, where the setter is
628 NULL, now raise an AttributeError when attempting to set or delete the
629 attribute. Previously a TypeError was raised, but this was inconsistent
630 with the equivalent pure-Python implementation.
631
Michael W. Hudson774479c2005-04-18 08:46:17 +0000632- It is now safe to call PyGILState_Release() before
633 PyEval_InitThreads() (note that if there is reason to believe there
634 are multiple threads around you still must call PyEval_InitThreads()
635 before using the Python API; this fix is for extension modules that
636 have no way of knowing if Python is multi-threaded yet).
637
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000638- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
639 disabled caused a crash.
640
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000641- Bug #1165306: instancemethod_new allowed the creation of a method
642 with im_class == im_self == NULL, which caused a crash when called.
643
Tim Petersecc6e6a2005-07-10 22:30:55 +0000644- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000645 fixes the crash seen in bug #1165761
646
Raymond Hettinger96229b12005-03-11 06:49:40 +0000647- Added two new builtins, any() and all().
648
Brett Cannon409d8f22005-03-05 06:47:57 +0000649- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000650 (e.g., ``class C(): pass`` is no longer a syntax error).
651 Patch #1176012 added support to the 'parser' module and 'compiler' package
652 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000653
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000654- Patch #1115086: Support PY_LONGLONG in structmember.
655
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000656- Bug #1155938: new style classes did not check that __init__() was
657 returning None.
658
Tim Petersecc6e6a2005-07-10 22:30:55 +0000659- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000660 ('\') with a specific error message.
661
Martin v. Löwisff232d72005-03-03 09:24:38 +0000662- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
663
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000664- Bug #1124295: the __name__ attribute of file objects was
665 inadvertently made inaccessible in restricted mode.
666
Tim Petersecc6e6a2005-07-10 22:30:55 +0000667- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000668 an ferror() call.
669
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000670- min() and max() now support key= arguments with the same meaning as in
671 list.sort().
672
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000673- The peephole optimizer now performs simple constant folding in expressions:
674 (2+3) --> (5).
675
Raymond Hettingera422c342005-01-11 03:03:27 +0000676- set and frozenset objects can now be marshalled. SF #1098985.
677
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000678- Bug #1077106: Poor argument checking could cause memory corruption
679 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000680
Jeremy Hyltonab630502005-02-04 18:44:06 +0000681- The parser did not complain about future statements in illegal
682 positions. It once again reports a syntax error if a future
683 statement occurs after anything other than a doc string.
684
Neil Schemenauercf52c072005-08-12 17:34:58 +0000685- Change the %s format specifier for str objects so that it returns a
686 unicode instance if the argument is not an instance of basestring and
687 calling __str__ on the argument returns a unicode instance.
688
Tim Petersf4e69282006-02-27 17:15:31 +0000689- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
690 current thread state when the auto-GIL-state machinery knows about
691 it (since the thread state is being deleted, continuing to remember it
692 can't help, but can hurt if another thread happens to get created with
693 the same thread id).
694

Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000721- The unicodedata module was updated to the 4.1 version of the Unicode
722 database. The 3.2 version is still available as unicodedata.db_3_2_0
723 for applications that require this specific version (such as IDNA).
724
Neal Norwitzb62c4332006-03-04 18:35:47 +0000725- The timing module is no longer built by default. It was deprecated

890 flag to -1 (unknown) since it can't tell from the date whether it should
891 be set.
892
Fred Drakead5177c2006-04-01 22:14:43 +0000893- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results

897 in attribute values.
898
Anthony Baxterc51ee692006-04-01 00:57:31 +0000899- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000900 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000901 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000902 module will not be built.
903
Tim Petersc17976e2006-04-01 00:26:53 +0000904- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
905 aren't officially supported here, and trying to use them will probably
906 raise an exception some day. But dicts have been allowed, and "mostly
907 worked", so support for them won't go away without warning.
908
Georg Brandl338ef7d2006-03-31 18:42:16 +0000909- Bug #1445068: getpass.getpass() can now be given an explicit stream
910 argument to specify where to write the prompt.
911
Georg Brandl22ec80b2006-03-31 18:25:44 +0000912- Patch #1462313, bug #1443328: the pickle modules now can handle classes

918 key to be used for signing the uploaded code.
919
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000920- Queue.Queue objects now support .task_done() and .join() methods
921 to make it easier to monitor when daemon threads have completed
922 processing all enqueued tasks. Patch #1455676.
923
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000924- popen2.Popen objects now preserve the command in a .cmd attribute.
925
Thomas Hellerc61c0492006-03-22 10:09:27 +0000926- Added the ctypes ffi package.
927
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000928- email 4.0 package now integrated. This is largely the same as the email 3.0
929 package that was included in Python 2.3, except that PEP 8 module names are
930 now used (e.g. mail.message instead of email.Message). The MIME classes
931 have been moved to a subpackage (e.g. email.mime.text instead of
932 email.MIMEText). The old names are still supported for now. Several
933 deprecated Message methods have been removed and lots of bugs have been
934 fixed. More details can be found in the email package documentation.
935
Walter Dörwald40108c92006-03-27 08:15:44 +0000936- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
937 (a subclass of tuple) that provides incremental decoders and encoders
938 (a way to use stateful codecs without the stream API). Python functions
939 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
940 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
941 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000942
Walter Dörwald067db482006-03-15 22:17:27 +0000943- Patch #1359365: Calling next() on a closed StringIO.String object raises
944 a ValueError instead of a StopIteration now (like file and cString.String do).
945 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
946 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000947
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000948- A regrtest option -w was added to re-run failed tests in verbose mode.

951 interpreter to exit.
952
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000953- The function get_count() has been added to the gc module, and gc.collect()
954 grew an optional 'generation' argument.
955
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000956- A library msilib to generate Windows Installer files, and a distutils
957 command bdist_msi have been added.

1016 LoadError as documented, instead of IOError. For compatibility,
1017 LoadError subclasses IOError.

Tim Peterse3547fd2005-12-16 23:13:57 +00001020 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1021 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1022 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1023 Ronald L. Rivest offered this advice for Python:
1024
1025 "The consensus of researchers in this area (at least as
1026 expressed at the NIST Hash Function Workshop 10/31/05),
1027 is that SHA-256 is a good choice for the time being, but
1028 that research should continue, and other alternatives may
1029 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001030
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001031- Added a subset of Fredrik Lundh's ElementTree package. Available

1139 class at all.
1140
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001141- distutils.commands.upload was added to support uploading distribution

1187
Raymond Hettingerbab41432005-02-05 01:31:19 +00001188- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1189
Guido van Rossumd0641422005-02-03 15:01:24 +00001190- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1191 disables recursive traversal through instance attributes, which can
1192 be exploited in various ways.
1193
Tim Peterse3547fd2005-12-16 23:13:57 +00001194- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001195 flags on the HTTP listening socket.
1196
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001197- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1198 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1199
Tim Peterse3547fd2005-12-16 23:13:57 +00001200- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001201 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1202

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001205- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1206
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001207- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1208
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001209- Enhancements to the csv module:
1210
1211 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001212 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001213 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001214 + Dialect parameter parsing has been re-implemented to improve error
1215 reporting.
1216 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1217 dictates.
1218 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001219 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001220 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001221 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1222 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001223 + reader now allows \r characters to be quoted (previously it only allowed
1224 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001225 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001226 + Dialect classes passed to the module are no longer instantiated by
1227 the module before being parsed (the former validation scheme required
1228 this, but the mechanism was unreliable).
1229 + The dialect registry now contains instances of the internal
1230 C-coded dialect type, rather than references to python objects.
1231 + the internal c-coded dialect type is now immutable.
1232 + register_dialect now accepts the same keyword dialect specifications
1233 as the reader and writer, allowing the user to register dialects
1234 without first creating a dialect class.
1235 + a configurable limit to the size of parsed fields has been added -
1236 previously, an unmatched quote character could result in the entire
1237 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001238 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001239 the parser field size limit (returning the former limit). The initial
1240 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001241 + A line_num attribute has been added to the reader object, which tracks
1242 the number of lines read from the source iterator. This is not
1243 the same as the number of records returned, as records can span
1244 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001245 + reader and writer objects were not being registered with the cyclic-GC.
1246 This has been fixed.
1247
Brett Cannone6539c42005-01-08 02:43:53 +00001248- _DummyThread objects in the threading module now delete self.__block that is
1249 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1250 lock primitives tend to be limited in number and thus should not be wasted on
1251 a _DummyThread object. Fixes bug #1089632.
1252
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001253- The imghdr module now detects Exif files.
1254
Raymond Hettinger6065d322004-12-20 23:51:53 +00001255- StringIO.truncate() now correctly adjusts the size attribute.
1256 (Bug #951915).
1257
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001258- locale.py now uses an updated locale alias table (built using
1259 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1260 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001261 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001262
Raymond Hettinger3557f422004-12-07 12:02:02 +00001263- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1264
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001265- the pickle module no longer accepts the deprecated None option in the
1266 args tuple returned by __reduce__().
1267
Brett Cannon84667c02004-12-07 03:25:18 +00001268- optparse now optionally imports gettext. This allows its use in setup.py.
1269
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001270- the pickle module no longer uses the deprecated bin parameter.
1271
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001272- the shelve module no longer uses the deprecated binary parameter.
1273
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001274- the pstats module no longer uses the deprecated ignore() method.
1275
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001276- the filecmp module no longer uses the deprecated use_statcache argument.
1277
Raymond Hettinger664347b2004-12-04 21:21:53 +00001278- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1279 extended or overridden by subclasses. Formerly, the subclassed method would
1280 be ignored by the rest of the module. (Bug #1078905).
1281
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001282- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001283 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001284
Walter Dörwald36733692004-12-22 12:50:50 +00001285- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1286 once when a size argument is given. This prevents a buffer overflow in the
1287 tokenizer with very long source lines.
1288
Barry Warsaw538561e2006-01-01 21:48:54 +00001289- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1290 immediately after creating the object, without any intervening
1291 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001292
Skip Montanaro05885812005-01-16 20:48:27 +00001293- The reconvert.quote function can now emit triple-quoted strings. The
1294 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001295
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001296- ``UserString.MutableString`` now supports negative indices in
1297 ``__setitem__`` and ``__delitem__``
1298
Greg Ward40407942005-03-05 02:53:17 +00001299- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1300 correctly.
1301
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001302- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1303 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1304 character even if the user has passed a size parameter to get a proper
1305 line ending. Remove the special handling of a "\r\n" that has been split
1306 between two lines.
1307
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001308- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1309 about illegal code points. The codec now supports PEP 293 style error
1310 handlers.
1311
Walter Dörwald78a78b02005-09-01 12:04:29 +00001312- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001313 from the input stream, so that the output is a byte string in the correct
1314 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001315
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001316- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1317 considering it exactly like a '*'.
1318
Walter Dörwald007f8df2005-10-09 19:42:27 +00001319- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1320 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001321
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001322- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1323
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001324- Patch #1413711: Certain patterns of differences were making difflib
1325 touch the recursion limit.
1326
Walter Dörwald58917a62006-03-31 15:26:22 +00001327- Bug #947906: An object oriented interface has been added to the calendar
1328 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001329 called as a script (e.g. via ``python -mcalendar``). Localized month and
1330 weekday names can be ouput (even if an exotic encoding is used) using
1331 special classes that use unicode.

1335
Neal Norwitz602d3392006-03-31 08:21:40 +00001336- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1337 by using -mieee gcc option.
1338
Martin v. Löwis86d66262006-02-17 08:40:11 +00001339- Patch #1432345: Make python compile on DragonFly.
1340
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001341- Build support for Win64-AMD64 was added.
1342
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001343- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1344
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001345- Patch #881820: look for openpty and forkpty also in libbsd.
1346
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001347- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1348 The zlib module is now builtin on Windows.
1349
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001350- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1351
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001352- Bug #1189330: configure did not correctly determine the necessary
1353 value of LINKCC if python was built with GCC 4.0.
1354
Trent Mick8321b422005-07-26 02:29:21 +00001355- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1356 vulnerability in zlib 1.2.1 and 1.2.2.
1357
Brett Cannon08cd5982005-04-24 22:26:38 +00001358- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1359 flags that change binary compatibility. Changes were also made to
1360 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001361 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001362
Bob Ippolitoed233462005-03-29 13:47:59 +00001363- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1364 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1365 no longer exists). This configure patch makes things right.
1366
Martin v. Löwise2713be2005-03-08 15:03:08 +00001367- Bug #1158607: Build with --disable-unicode again.
1368
Brett Cannon46d96232005-02-16 00:07:19 +00001369- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1370 defined. Discovered as a result of not being able to build on OS X.
1371
Brett Cannon516592f2004-12-07 00:42:59 +00001372- setup.py now uses the directories specified in LDFLAGS using the -L option
1373 and in CPPFLAGS using the -I option for adding library and include
1374 directories, respectively, for compiling extension modules against. This has
1375 led to the core being compiled using the values in CPPFLAGS. It also removes
1376 the need for the special-casing of both DarwinPorts and Fink for darwin since
1377 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1378 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1379 Fink, ``-I/opt/local/include`` for DarwinPorts).
1380
Brett Cannon43802422005-02-10 20:48:03 +00001381- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1382 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1383 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1384 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001386C API
1387-----
1388
Tim Petersc9d78aa2006-03-26 23:27:58 +00001389- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1390 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1391 is obtained via the ``PyObject_`` family, it must be released via the
1392 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1393 always been officially true, but when Python's small-object allocator was
1394 introduced, an attempt was made to cater to a few extension modules
1395 discovered at the time that obtained memory via ``PyObject_New`` but
1396 released it via ``PyMem_DEL``. It's years later, and if such code still
1397 exists it will fail now (probably with segfaults, but calling wrong
1398 low-level memory management functions can yield many symptoms).
1399
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001400- Added a C API for set and frozenset objects.
1401
Raymond Hettinger66517482004-12-03 11:45:13 +00001402- Removed PyRange_New().

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001404- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1405 mapping argument now. This string is used as a mapping table. Byte values
1406 greater than the length of the string and 0xFFFE are treated as undefined
1407 mappings.
