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
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000105- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
106 accept it without potentially using an uninitialized pointer.
107
108- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
109 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
110 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000111
Gregory P. Smith372b5832006-06-05 18:48:21 +0000112- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000113 [pybsddb project SF patch number 1466734]
114
Gregory P. Smith372b5832006-06-05 18:48:21 +0000115- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
116 parameter is supplied. [SF pybsddb bug #1477863]
117
118
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000119Library
120-------
121
Tim Petersd6a9eef2006-06-05 01:48:21 +0000122- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
123 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000124
Martin v. Löwis3f767792006-06-04 19:36:28 +0000125- Patch #1359618: Speed up charmap encoder by using a trie structure
126 for lookup.
127
Tim Petersd609b1a2006-06-02 23:22:51 +0000128- The functions in the ``pprint`` module now sort dictionaries by key
129 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
130 if and only if its display required more than one line, although that
131 wasn't documented. The new behavior increases predictability; e.g.,
132 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
133
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000134- Patch #1497027: try HTTP digest auth before basic auth in urllib2
135 (thanks for J. J. Lee).
136
Georg Brandl2b330372006-05-28 20:23:12 +0000137- Patch #1496206: improve urllib2 handling of passwords with respect to
138 default HTTP and HTTPS ports.
139
George Yoshidaf3c65de2006-05-28 16:39:09 +0000140- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
141
Bob Ippolito7298f272006-05-23 18:43:47 +0000142- Patch #1281707: speed up gzip.readline.
143
Georg Brandlb89316f2006-05-17 15:51:16 +0000144- Patch #1180296: Two new functions were added to the locale module:
145 format_string() to get the effect of "format % items" but locale-aware,
146 and currency() to format a monetary number with currency sign.
147
Georg Brandle3a25832006-05-17 14:56:04 +0000148- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
149 and several features added, such as speed and geometry control.
150
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000151- Patch #1488881: add support for external file objects in bz2 compressed
152 tarfiles.
153
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000154- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
155 stdout arguments, making it possible to redirect input and output
156 for remote debugging.
157
158- Patch #1484695: Update the tarfile module to version 0.8. This fixes
159 a couple of issues, notably handling of long file names using the
160 GNU LONGNAME extension.
161
162- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
163 new flag when ``name`` is already the name of an option flag.
164
165- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
166 package.
167
168- Patch #1472854: make the rlcompleter.Completer class usable on non-
169 UNIX platforms.
170
171- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000198What's New in Python 2.5 alpha 2?
199=================================
200
201*Release date: 27-APR-2006*
202
203Core and builtins
204-----------------
205
Thomas Heller1b046642006-04-18 18:51:06 +0000206- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
207 by converting these apis from macros into exported functions again:
208
209 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
210 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
211 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
212 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
213 PyRun_String Py_CompileString
214
Martin v. Löwis45294a92006-04-18 06:24:08 +0000215- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
216
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000217- All uses of PyStructSequence_InitType have been changed to initialize
218 the type objects only once, even if the interpreter is initialized
219 multiple times.
220
Neal Norwitz61546162006-04-14 05:20:28 +0000221- Bug #1454485, array.array('u') could crash the interpreter. This was
222 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
223 to unicode when it didn't make sense. 'u#' now requires a unicode string.
224
225- Py_UNICODE is unsigned. It was always documented as unsigned, but
226 due to a bug had a signed value in previous versions.
227
Tim Peters3a5e8b12006-04-11 01:44:07 +0000228- Patch #837242: ``id()`` of any Python object always gives a positive
229 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
230 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000231 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000232 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000233
Tim Peters3a5e8b12006-04-11 01:44:07 +0000234 def __hash__(self):
235 return id(self) # WRONG
236
237 because a hash result must be a (short) Python int but it was always
238 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000239 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000240 was always usable as a hash value before this patch. That's no longer
241 necessarily so.
242
243- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000244 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000245 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000246 #1454844)
247
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000248- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
249 involving generators that have paused outside of any ``try`` or ``with``
250 blocks. (In 2.5a1, a paused generator that was part of a reference
251 cycle could not be garbage collected, regardless of whether it was
252 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000254Extension Modules
255-----------------
256
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000257- Patch #1191065: Fix preprocessor problems on systems where recvfrom
258 is a macro.
259
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000260- Bug #1467952: os.listdir() now correctly raises an error if readdir()
261 fails with an error condition.
262
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000263- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
264
265- Bug #1117761: bsddb.*open() no longer raises an exception when using
266 the cachesize parameter.
267
268- Bug #1149413: bsddb.*open() no longer raises an exception when using
269 a temporary db (file=None) with the 'n' flag to truncate on open.
270
271- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
272 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000273
Armin Rigoa9017c32006-04-19 11:50:27 +0000274- Patch #1062014: AF_UNIX sockets under Linux have a special
275 abstract namespace that is now fully supported.
276
Anthony Baxter51bcb682006-04-05 14:51:42 +0000277Library
278-------
279
Tim Peters711bf302006-04-25 03:31:36 +0000280- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
281 a doctest to be skipped (the code is not run, and the expected output
282 or exception is ignored).
283
Nick Coghlanda2268f2006-04-24 04:37:15 +0000284- Fixed contextlib.nested to cope with exceptions being raised and
285 caught inside exit handlers.
286
Greg Wardab05edc2006-04-23 03:47:58 +0000287- Updated optparse module to Optik 1.5.1 (allow numeric constants in
288 hex, octal, or binary; add ``append_const`` action; keep going if
289 gettext cannot be imported; added ``OptionParser.destroy()`` method;
290 added ``epilog`` for better help generation).
291
Tim Peters21fbd572006-04-21 21:18:10 +0000292- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
293 called from a thread spawned as a side effect of importing a module.
294
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000295- The pydoc module now supports documenting packages contained in
296 .zip or .egg files.
297
298- The pkgutil module now has several new utility functions, such
299 as ``walk_packages()`` to support working with packages that are either
300 in the filesystem or zip files.
301
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000302- The mailbox module can now modify and delete messages from
303 mailboxes, in addition to simply reading them. Thanks to Gregory
304 K. Johnson for writing the code, and to the 2005 Google Summer of
305 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000306
Tim Petersc7605f22006-04-17 21:12:33 +0000307- The ``__del__`` method of class ``local`` in module ``_threading_local``
308 returned before accomplishing any of its intended cleanup.
309
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000310- Patch #790710: Add breakpoint command lists in pdb.
311
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000312- Patch #1063914: Add Tkinter.Misc.clipboard_get().
313
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000314- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
315
Anthony Baxtere29002c2006-04-12 12:07:31 +0000316- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
317 Windows. Bug #1469163.
318
Phillip J. Eby47032112006-04-11 01:07:43 +0000319- The warnings, linecache, inspect, traceback, site, and doctest modules
320 were updated to work correctly with modules imported from zipfiles or
321 via other PEP 302 __loader__ objects.
322
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000323- Patch #1467770: Reduce usage of subprocess._active to processes which
324 the application hasn't waited on.
325
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000326- Patch #1462222: Fix Tix.Grid.
327
Neal Norwitza31bf182006-04-09 03:35:43 +0000328- Fix exception when doing glob.glob('anything*/')
329
Skip Montanaro262fb922006-04-21 02:31:07 +0000330- The pstats.Stats class accepts an optional stream keyword argument to
331 direct output to an alternate file-like object.

334-----
335
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000336- The Makefile now has a reindent target, which runs reindent.py on
337 the library.
338
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000339- Patch #1470875: Building Python with MS Free Compiler
340
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000341- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000342
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000343- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
344 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000345 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000346 CXX from --with-cxx-main, see description in README.
347
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000348- Patch #1429775: Link extension modules with the shared libpython.
349
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000350- Fixed a libffi build problem on MIPS systems.
351
Tim Peters8931ff12006-05-13 23:28:20 +0000352- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
353 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
354 and "%zu" for unsigned integers of type ``size_t``.
355
Anthony Baxter51bcb682006-04-05 14:51:42 +0000356Tests
357-----
358
Nick Coghlanda2268f2006-04-24 04:37:15 +0000359- test_contextlib now checks contextlib.nested can cope with exceptions
360 being raised and caught inside exit handlers.
361
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000362- test_cmd_line now checks operation of the -m and -c command switches
363
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000364- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
365 it separately and by hand. It also wasn't cleaning up its changes to
366 the current Decimal context.
367
Thomas Woutersabd08882006-04-26 15:53:30 +0000368- regrtest.py now has a -M option to run tests that test the new limits of
369 containers, on 64-bit architectures. Running these tests is only sensible
370 on 64-bit machines with more than two gigabytes of memory. The argument
371 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000379Documentation
380-------------
381
Tim Petersb06d28c2006-05-12 01:57:59 +0000382- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
383
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000384- PEP 343: Added Context Types section to the library reference
385 and attempted to bring other PEP 343 related documentation into
386 line with the implementation and/or python-dev discussions.
387
Tim Peters8dc73d22006-04-24 02:03:16 +0000388- Bug #1337990: clarified that ``doctest`` does not support examples
389 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000392What's New in Python 2.5 alpha 1?
393=================================
394
Anthony Baxterebed3f62006-04-03 15:03:44 +0000395*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000396
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000397Core and builtins
398-----------------
399
Nick Coghlan43832302006-04-23 17:04:07 +0000400- PEP 338: -m command line switch now delegates to runpy.run_module
401 allowing it to support modules in packages and zipfiles
402
Martin v. Löwisc661b882006-04-20 04:54:23 +0000403- On Windows, .DLL is not an accepted file name extension for
404 extension modules anymore; extensions are only found if they
405 end in .PYD.
406
Martin v. Löwisea62d252006-04-03 10:56:49 +0000407- Bug #1421664: sys.stderr.encoding is now set to the same value as
408 sys.stdout.encoding.
409
Neal Norwitz92e212f2006-04-03 04:48:37 +0000410- __import__ accepts keyword arguments.
411
Georg Brandlccadf842006-03-31 18:54:53 +0000412- Patch #1460496: round() now accepts keyword arguments.
413
Anthony Baxter262c00a2006-03-30 10:53:17 +0000414- Fixed bug #1459029 - unicode reprs were double-escaped.
415
Hye-Shik Changd478f342006-03-23 12:32:36 +0000416- Patch #1396919: The system scope threads are reenabled on FreeBSD
417 5.4 and later versions.
418
Neal Norwitze98ccf62006-03-23 05:39:47 +0000419- Bug #1115379: Compiling a Unicode string with an encoding declaration
420 now gives a SyntaxError.
421
Georg Brandlabd1ff82006-03-18 07:59:59 +0000422- Previously, Python code had no easy way to access the contents of a
423 cell object. Now, a ``cell_contents`` attribute has been added
424 (closes patch #1170323).
425
Tim Peterscf79aac2006-03-16 01:14:46 +0000426- Patch #1123430: Python's small-object allocator now returns an arena to
427 the system ``free()`` when all memory within an arena becomes unused
428 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
429 freed. Some applications will see a drop in virtual memory size now,
430 especially long-running applications that, from time to time, temporarily
431 use a large number of small objects. Note that when Python returns an
432 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000433 platform C library will in turn return that memory to the operating system.
434 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000435 appears to be effective at least on Microsoft C and gcc-based systems.
436 Thanks to Evan Jones for hard work and patience.
437
Georg Brandl533ff6f2006-03-08 18:09:27 +0000438- Patch #1434038: property() now uses the getter's docstring if there is
439 no "doc" argument given. This makes it possible to legitimately use
440 property() as a decorator to produce a read-only property.
441
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000442- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
443 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
444 of requiring an int or long in slicing and a few other contexts, enabling
445 other objects (e.g. Numeric Python's integers) to be used as slice indices.
446
Neal Norwitz995acdf2006-03-07 05:01:00 +0000447- Fixed various bugs reported by Coverity's Prevent tool.
448
Brett Cannonbf364092006-03-01 04:25:17 +0000449- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
450 new exception base class, BaseException, which has a new message attribute.
451 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
452 Raising a string exception now raises a DeprecationWarning.
453
Thomas Woutersfb609f42006-02-28 16:37:25 +0000454- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
455 explicitly relative, using 'from .module import name' to mean 'from the same
456 package as this module is in. Imports without dots still default to the
457 old relative-then-absolute, unless 'from __future__ import
458 absolute_import' is used.
459
Brett Cannona7446e32006-02-27 23:39:10 +0000460- Properly check if 'warnings' raises an exception (usually when a filter set
461 to "error" is triggered) when raising a warning for raising string
462 exceptions.
463
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000464- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000465 The name was removed from Include/code.h.
466
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000467- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000468
Guido van Rossum1968ad32006-02-25 22:38:04 +0000469- Patch 1433928:
470 - The copy module now "copies" function objects (as atomic objects).
471 - dict.__getitem__ now looks for a __missing__ hook before raising
472 KeyError.
473
Tim Peters84ef21c2006-02-28 20:39:06 +0000474- PEP 343: with statement implemented. Needs ``from __future__ import
475 with_statement``. Use of 'with' as a variable will generate a warning.
476 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000477 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000478 The following objects have __context__ methods:
479 - The built-in file type.
480 - The thread.LockType type.
481 - The following types defined by the threading module:
482 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
483 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000484
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000485- Fix the encodings package codec search function to only search
486 inside its own package. Fixes problem reported in patch #1433198.
487
488 Note: Codec packages should implement and register their own
489 codec search function. PEP 100 has the details.
490
Tim Peters9ea89d22006-06-04 03:26:02 +0000491- PEP 353: Using ``Py_ssize_t`` as the index type.
492
493- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
494 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
495 now allow Python to make use of memory blocks exceeding 2**32 bytes for
496 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
497 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000498
Neal Norwitzfc76d632006-01-10 06:03:13 +0000499- Patch #1400181, fix unicode string formatting to not use the locale.
500 This is how string objects work. u'%f' could use , instead of .
501 for the decimal point. Now both strings and unicode always use periods.
502
Neal Norwitz671b9e32006-01-09 07:07:12 +0000503- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
504 configure would break checking curses.h.
505
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000506- Bug #959576: The pwd module is now builtin. This allows Python to be
507 built on UNIX platforms without $HOME set.
508
Neal Norwitzc10978f2005-12-19 06:07:16 +0000509- Bug #1072182, fix some potential problems if characters are signed.
510
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000511- Bug #889500, fix line number on SyntaxWarning for global declarations.
512
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000513- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
514
Neal Norwitze7214a12005-12-18 05:03:17 +0000515- Support for converting hex strings to floats no longer works.
516 This was not portable. float('0x3') now raises a ValueError.
517
Barry Warsaw2a38a862005-12-18 01:27:35 +0000518- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000519 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000520 is now displayed in interactive prompt banner.
521
Georg Brandlfa166682005-12-17 21:45:17 +0000522- Implementation of PEP 341 - Unification of try/except and try/finally.
523 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000524 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000525
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000526- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
527 now encodes backslash correctly.
528
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000529- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
530
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000531- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000532 and long longs.
533
Neal Norwitz67715f02005-11-09 06:59:35 +0000534- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000535 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000536 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000537
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000538- Replaced most Unicode charmap codecs with new ones using the
539 new Unicode translate string feature in the builtin charmap
540 codec; the codecs were created from the mapping tables available
541 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
542 encodings now include a mapping for the Apple logo)
543
Tim Peterse3547fd2005-12-16 23:13:57 +0000544- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000545
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000546- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000547
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000548- A new AST parser implementation was completed. The abstract
549 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000550 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000551
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000552- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000553 The following code now raises a SyntaxError: foo(a = i for i in range(10))
554
Neal Norwitz708e51a2005-10-03 04:48:15 +0000555- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
556
Neal Norwitz11bd1192005-10-03 00:54:56 +0000557- SF Bug #887946: fix segfault when redirecting stdin from a directory.
558 Provide a warning when a directory is passed on the command line.
559
Neal Norwitz40d37812005-10-02 01:48:49 +0000560- Fix segfault with invalid coding.
561
562- SF bug #772896: unknown encoding results in MemoryError.
563
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000564- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000565 supported a __len__() method which evaluated to False when the iterator
566 was empty.
567
Guido van Rossum630db602005-09-20 18:49:54 +0000568- On 64-bit platforms, when __len__() returns a value that cannot be
569 represented as a C int, raise OverflowError.
570
Skip Montanarof8948ca2005-09-19 03:54:46 +0000571- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000572 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000573
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000574- SF bug #893549: parsing keyword arguments was broken with a few format
575 codes.
576
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000577- Changes donated by Elemental Security to make it work on AIX 5.3
578 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
579 bug #105470: test_pwd fails on 64bit system (Opteron).
580
Guido van Rossum539c6622005-09-14 17:49:54 +0000581- Changes donated by Elemental Security to make it work on HP-UX 11 on
582 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
583
Georg Brandl4550b8d2005-08-26 06:43:52 +0000584- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000585 (fixes bug #1119418).
586
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000587- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
588
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000589- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
590 exceptions that cause a function to exit.
591
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000592- The implementation of set() and frozenset() was revised to use its
593 own internal data structure. Memory consumption is reduced by 1/3
594 and there are modest speed-ups as well. The API is unchanged.
595
Tim Petersde7990b2005-07-17 23:45:23 +0000596- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
597
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000598- SF bug #1229429: PyObject_CallMethod failed to decrement some
599 reference counts in some error exit cases.
600
Tim Petersecc6e6a2005-07-10 22:30:55 +0000601- SF bug #1185883: Python's small-object memory allocator took over
602 a block managed by the platform C library whenever a realloc specified
603 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000604 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000605 portable way to copy data from the C-managed block into Python's
606 small-object space without risking a memory fault. Python's small-object
607 realloc now leaves such blocks under the control of the platform C

Michael W. Hudsonb8963812005-07-05 15:21:58 +0000610- SF bug #1232517: An overflow error was not detected properly when
611 attempting to convert a large float to an int in os.utime().
612
Raymond Hettinger3296e692005-06-29 23:29:56 +0000613- SF bug #1224347: hex longs now print with lowercase letters just
614 like their int counterparts.
615
Michael W. Hudson188d4362005-06-20 16:52:57 +0000616- SF bug #1163563: the original fix for bug #1010677 ("thread Module
617 Breaks PyGILState_Ensure()") broke badly in the case of multiple
618 interpreter states; back out that fix and do a better job (see
619 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
620 for a longer write-up of the problem).
621
Michael W. Hudsondf888462005-06-03 14:41:55 +0000622- SF patch #1180995: marshal now uses a binary format by default when
623 serializing floats.
624
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000625- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
626 the routines that promise to produce IEEE 754 binary representations
627 of floats now simply copy bytes around.
628
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000629- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
630 278.
631
Brett Cannonc3647ac2005-04-26 03:45:26 +0000632- patch #1109424: int, long, float, complex, and unicode now check for the
633 proper magic slot for type conversions when subclassed. Previously the
634 magic slot was ignored during conversion. Semantics now match the way
635 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000636 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000637 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000638 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000639
Barry Warsawc8d907c2005-04-19 23:43:40 +0000640- Descriptors defined in C with a PyGetSetDef structure, where the setter is
641 NULL, now raise an AttributeError when attempting to set or delete the
642 attribute. Previously a TypeError was raised, but this was inconsistent
643 with the equivalent pure-Python implementation.
644
Michael W. Hudson774479c2005-04-18 08:46:17 +0000645- It is now safe to call PyGILState_Release() before
646 PyEval_InitThreads() (note that if there is reason to believe there
647 are multiple threads around you still must call PyEval_InitThreads()
648 before using the Python API; this fix is for extension modules that
649 have no way of knowing if Python is multi-threaded yet).
650
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000651- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
652 disabled caused a crash.
653
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000654- Bug #1165306: instancemethod_new allowed the creation of a method
655 with im_class == im_self == NULL, which caused a crash when called.
656
Tim Petersecc6e6a2005-07-10 22:30:55 +0000657- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000658 fixes the crash seen in bug #1165761
659
Raymond Hettinger96229b12005-03-11 06:49:40 +0000660- Added two new builtins, any() and all().
661
Brett Cannon409d8f22005-03-05 06:47:57 +0000662- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000663 (e.g., ``class C(): pass`` is no longer a syntax error).
664 Patch #1176012 added support to the 'parser' module and 'compiler' package
665 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000666
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000667- Patch #1115086: Support PY_LONGLONG in structmember.
668
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000669- Bug #1155938: new style classes did not check that __init__() was
670 returning None.
671
Tim Petersecc6e6a2005-07-10 22:30:55 +0000672- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000673 ('\') with a specific error message.
674
Martin v. Löwisff232d72005-03-03 09:24:38 +0000675- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
676
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000677- Bug #1124295: the __name__ attribute of file objects was
678 inadvertently made inaccessible in restricted mode.
679
Tim Petersecc6e6a2005-07-10 22:30:55 +0000680- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000681 an ferror() call.
682
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000683- min() and max() now support key= arguments with the same meaning as in
684 list.sort().
685
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000686- The peephole optimizer now performs simple constant folding in expressions:
687 (2+3) --> (5).
688
Raymond Hettingera422c342005-01-11 03:03:27 +0000689- set and frozenset objects can now be marshalled. SF #1098985.
690
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000691- Bug #1077106: Poor argument checking could cause memory corruption
692 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000693
Jeremy Hyltonab630502005-02-04 18:44:06 +0000694- The parser did not complain about future statements in illegal
695 positions. It once again reports a syntax error if a future
696 statement occurs after anything other than a doc string.
697
Neil Schemenauercf52c072005-08-12 17:34:58 +0000698- Change the %s format specifier for str objects so that it returns a
699 unicode instance if the argument is not an instance of basestring and
700 calling __str__ on the argument returns a unicode instance.
701
Tim Petersf4e69282006-02-27 17:15:31 +0000702- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
703 current thread state when the auto-GIL-state machinery knows about
704 it (since the thread state is being deleted, continuing to remember it
705 can't help, but can hurt if another thread happens to get created with
706 the same thread id).
707

732 SS2 (single-shift 2) escape sequences correctly.
733
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000734- The unicodedata module was updated to the 4.1 version of the Unicode
735 database. The 3.2 version is still available as unicodedata.db_3_2_0
736 for applications that require this specific version (such as IDNA).
737
Neal Norwitzb62c4332006-03-04 18:35:47 +0000738- The timing module is no longer built by default. It was deprecated
739 in PEP 4 in Python 2.0 or earlier.
740
Guido van Rossum1968ad32006-02-25 22:38:04 +0000741- Patch 1433928: Added a new type, defaultdict, to the collections module.

743
Georg Brandldbd83392006-02-20 09:42:33 +0000744- Bug #854823: socketmodule now builds on Sun platforms even when

884
Raymond Hettingerb2594052004-12-05 09:25:51 +0000885- itertools.islice() now accepts None for the start and step arguments.
886 This allows islice() to work more readily with slices:

896-------
897
Nick Coghlan43832302006-04-23 17:04:07 +0000898- PEP 338: new module runpy defines a run_module function to support
899 executing modules which provide access to source code or a code object
900 via the PEP 302 import mechanisms.
901

Anthony Baxterc51ee692006-04-01 00:57:31 +0000912- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000913 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000914 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000915 module will not be built.
916
Tim Petersc17976e2006-04-01 00:26:53 +0000917- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
918 aren't officially supported here, and trying to use them will probably
919 raise an exception some day. But dicts have been allowed, and "mostly
920 worked", so support for them won't go away without warning.
921
Georg Brandl338ef7d2006-03-31 18:42:16 +0000922- Bug #1445068: getpass.getpass() can now be given an explicit stream

940
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000941- email 4.0 package now integrated. This is largely the same as the email 3.0
942 package that was included in Python 2.3, except that PEP 8 module names are
943 now used (e.g. mail.message instead of email.Message). The MIME classes
944 have been moved to a subpackage (e.g. email.mime.text instead of
945 email.MIMEText). The old names are still supported for now. Several
946 deprecated Message methods have been removed and lots of bugs have been
947 fixed. More details can be found in the email package documentation.
948
Walter Dörwald40108c92006-03-27 08:15:44 +0000949- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
950 (a subclass of tuple) that provides incremental decoders and encoders
951 (a way to use stateful codecs without the stream API). Python functions
952 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
953 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
954 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000955

957 a ValueError instead of a StopIteration now (like file and cString.String do).
958 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
959 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000960

1035 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1036 Ronald L. Rivest offered this advice for Python:
1037
1038 "The consensus of researchers in this area (at least as
1039 expressed at the NIST Hash Function Workshop 10/31/05),
1040 is that SHA-256 is a good choice for the time being, but
1041 that research should continue, and other alternatives may
1042 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001043
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001044- Added a subset of Fredrik Lundh's ElementTree package. Available

Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001154- distutils.commands.upload was added to support uploading distribution
1155 files to PyPI.
1156
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001157- distutils.commands.register now encodes the data as UTF-8 before posting
1158 them to PyPI.
1159
Raymond Hettinger267b8682005-03-27 10:47:39 +00001160- decimal operator and comparison methods now return NotImplemented
1161 instead of raising a TypeError when interacting with other types. This
1162 allows other classes to implement __radd__ style methods and have them
1163 work as expected.
1164
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001165- Bug #1163325: Decimal infinities failed to hash. Attempting to
1166 hash a NaN raised an InvalidOperation instead of a TypeError.
1167
Tim Petersecc6e6a2005-07-10 22:30:55 +00001168- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001169 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1170
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001171- Patch #1043890: Add extractall method to tarfile.
1172
Martin v. Löwisc72dd382005-03-04 13:50:17 +00001173- Patch #1075887: Don't require MSVC in distutils if there is nothing
1174 to build.
1175
Martin v. Löwis637431b2005-03-03 23:12:42 +00001176- Patch #1103407: Properly deal with tarfile iterators when untarring
1177 symbolic links on Windows.
1178
Tim Petersecc6e6a2005-07-10 22:30:55 +00001179- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001180 profile.py if available.
1181
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001182- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1183
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001184- Patch #1117454: Remove code to special-case cookies without values
1185 in LWPCookieJar.
1186
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001187- Patch #1117339: Add cookielib special name tests.
1188
Martin v. Löwise869eb12005-03-03 09:46:07 +00001189- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1190
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001191- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1192
Martin v. Löwisdf241532005-03-03 08:17:42 +00001193- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1194
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001195- Patch #1104111: Alter setup.py --help and --help-commands.
1196
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001197- Patch #1121234: Properly cleanup _exit and tkerror commands.
1198
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001199- Patch #1049151: xdrlib now unpacks booleans as True or False.
1200
Raymond Hettingerbab41432005-02-05 01:31:19 +00001201- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1202
Guido van Rossumd0641422005-02-03 15:01:24 +00001203- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1204 disables recursive traversal through instance attributes, which can
1205 be exploited in various ways.
1206
Tim Peterse3547fd2005-12-16 23:13:57 +00001207- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001208 flags on the HTTP listening socket.
1209
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001210- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1211 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1212
Tim Peterse3547fd2005-12-16 23:13:57 +00001213- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001214 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1215
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001216- Bug #1110478: Revert os.environ.update to do putenv again.
1217
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001218- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1219
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001220- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1221
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001222- Enhancements to the csv module:
1223
1224 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001225 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001226 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001227 + Dialect parameter parsing has been re-implemented to improve error
1228 reporting.
1229 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1230 dictates.
1231 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001232 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001233 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001234 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1235 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001236 + reader now allows \r characters to be quoted (previously it only allowed
1237 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001238 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001239 + Dialect classes passed to the module are no longer instantiated by
1240 the module before being parsed (the former validation scheme required
1241 this, but the mechanism was unreliable).
1242 + The dialect registry now contains instances of the internal
1243 C-coded dialect type, rather than references to python objects.
1244 + the internal c-coded dialect type is now immutable.
1245 + register_dialect now accepts the same keyword dialect specifications
1246 as the reader and writer, allowing the user to register dialects
1247 without first creating a dialect class.
1248 + a configurable limit to the size of parsed fields has been added -
1249 previously, an unmatched quote character could result in the entire
1250 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001251 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001252 the parser field size limit (returning the former limit). The initial
1253 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001254 + A line_num attribute has been added to the reader object, which tracks
1255 the number of lines read from the source iterator. This is not
1256 the same as the number of records returned, as records can span
1257 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001258 + reader and writer objects were not being registered with the cyclic-GC.
1259 This has been fixed.
1260
Brett Cannone6539c42005-01-08 02:43:53 +00001261- _DummyThread objects in the threading module now delete self.__block that is
1262 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1263 lock primitives tend to be limited in number and thus should not be wasted on
1264 a _DummyThread object. Fixes bug #1089632.
1265
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001266- The imghdr module now detects Exif files.
1267
Raymond Hettinger6065d322004-12-20 23:51:53 +00001268- StringIO.truncate() now correctly adjusts the size attribute.
1269 (Bug #951915).
1270
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001271- locale.py now uses an updated locale alias table (built using
1272 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1273 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001274 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001275
Raymond Hettinger3557f422004-12-07 12:02:02 +00001276- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1277
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001278- the pickle module no longer accepts the deprecated None option in the
1279 args tuple returned by __reduce__().
1280
Brett Cannon84667c02004-12-07 03:25:18 +00001281- optparse now optionally imports gettext. This allows its use in setup.py.
1282
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001283- the pickle module no longer uses the deprecated bin parameter.
1284
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001285- the shelve module no longer uses the deprecated binary parameter.
1286
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001287- the pstats module no longer uses the deprecated ignore() method.
1288
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001289- the filecmp module no longer uses the deprecated use_statcache argument.
1290
Raymond Hettinger664347b2004-12-04 21:21:53 +00001291- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1292 extended or overridden by subclasses. Formerly, the subclassed method would
1293 be ignored by the rest of the module. (Bug #1078905).
1294
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001295- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001296 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001297
Walter Dörwald36733692004-12-22 12:50:50 +00001298- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1299 once when a size argument is given. This prevents a buffer overflow in the
1300 tokenizer with very long source lines.
1301
Barry Warsaw538561e2006-01-01 21:48:54 +00001302- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1303 immediately after creating the object, without any intervening
1304 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001305
Skip Montanaro05885812005-01-16 20:48:27 +00001306- The reconvert.quote function can now emit triple-quoted strings. The
1307 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001308
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001309- ``UserString.MutableString`` now supports negative indices in
1310 ``__setitem__`` and ``__delitem__``
1311
Greg Ward40407942005-03-05 02:53:17 +00001312- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1313 correctly.
1314
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001315- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1316 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1317 character even if the user has passed a size parameter to get a proper
1318 line ending. Remove the special handling of a "\r\n" that has been split
1319 between two lines.
1320
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001321- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1322 about illegal code points. The codec now supports PEP 293 style error
1323 handlers.
1324
Walter Dörwald78a78b02005-09-01 12:04:29 +00001325- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001326 from the input stream, so that the output is a byte string in the correct
1327 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001328
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001329- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1330 considering it exactly like a '*'.
1331
Walter Dörwald007f8df2005-10-09 19:42:27 +00001332- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1333 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001334
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001335- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1336
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001337- Patch #1413711: Certain patterns of differences were making difflib
1338 touch the recursion limit.
1339
Walter Dörwald58917a62006-03-31 15:26:22 +00001340- Bug #947906: An object oriented interface has been added to the calendar
1341 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001342 called as a script (e.g. via ``python -mcalendar``). Localized month and
1343 weekday names can be ouput (even if an exotic encoding is used) using
1344 special classes that use unicode.

1347-----
1348
Neal Norwitz602d3392006-03-31 08:21:40 +00001349- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1350 by using -mieee gcc option.
1351
Martin v. Löwis86d66262006-02-17 08:40:11 +00001352- Patch #1432345: Make python compile on DragonFly.
1353
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001354- Build support for Win64-AMD64 was added.
1355
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001356- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1357
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001358- Patch #881820: look for openpty and forkpty also in libbsd.
1359
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001360- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1361 The zlib module is now builtin on Windows.
1362
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001363- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1364
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001365- Bug #1189330: configure did not correctly determine the necessary
1366 value of LINKCC if python was built with GCC 4.0.
1367
Trent Mick8321b422005-07-26 02:29:21 +00001368- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1369 vulnerability in zlib 1.2.1 and 1.2.2.
1370
Brett Cannon08cd5982005-04-24 22:26:38 +00001371- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1372 flags that change binary compatibility. Changes were also made to
1373 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001374 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001375
Bob Ippolitoed233462005-03-29 13:47:59 +00001376- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1377 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1378 no longer exists). This configure patch makes things right.
1379
Martin v. Löwise2713be2005-03-08 15:03:08 +00001380- Bug #1158607: Build with --disable-unicode again.
1381
Brett Cannon46d96232005-02-16 00:07:19 +00001382- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1383 defined. Discovered as a result of not being able to build on OS X.
1384
Brett Cannon516592f2004-12-07 00:42:59 +00001385- setup.py now uses the directories specified in LDFLAGS using the -L option
1386 and in CPPFLAGS using the -I option for adding library and include
1387 directories, respectively, for compiling extension modules against. This has
1388 led to the core being compiled using the values in CPPFLAGS. It also removes
1389 the need for the special-casing of both DarwinPorts and Fink for darwin since
1390 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1391 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1392 Fink, ``-I/opt/local/include`` for DarwinPorts).
1393
Brett Cannon43802422005-02-10 20:48:03 +00001394- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1395 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1396 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1397 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001399C API
1400-----
1401
Tim Petersc9d78aa2006-03-26 23:27:58 +00001402- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1403 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1404 is obtained via the ``PyObject_`` family, it must be released via the
1405 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1406 always been officially true, but when Python's small-object allocator was
1407 introduced, an attempt was made to cater to a few extension modules
1408 discovered at the time that obtained memory via ``PyObject_New`` but
1409 released it via ``PyMem_DEL``. It's years later, and if such code still
1410 exists it will fail now (probably with segfaults, but calling wrong
1411 low-level memory management functions can yield many symptoms).
1412
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001413- Added a C API for set and frozenset objects.
1414
Raymond Hettinger66517482004-12-03 11:45:13 +00001415- Removed PyRange_New().
1416
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001417- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1418 mapping argument now. This string is used as a mapping table. Byte values
1419 greater than the length of the string and 0xFFFE are treated as undefined
1420 mappings.
