Hye-Shik Change6a1cb92006-06-23 21:16:18 +000015- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
16 omit a default "error" argument for NULL pointer. This allows
17 the parser to take a codec from cjkcodecs again.

21
Martin v. Löwis7596e832006-07-01 15:33:37 +000022- Bug #1513223: .close() of a _socketobj now releases the underlying
23 socket again, which then gets closed as it becomes unreferenced.
24
Thomas Hellerbde08132006-06-29 18:34:15 +000025- The '_ctypes' extension module now works when Python is configured
26 with the --without-threads option.
27
Fred Drake10497c82006-06-29 02:57:48 +000028- Bug #1504333: Make sgmllib support angle brackets in quoted
29 attribute values.
30
31- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
32 sgmllib ('[' and ']' were not accepted).
33
Georg Brandl1be63af2006-06-28 20:23:25 +000034- Fix a bug in the turtle module's end_fill function.
35
Brett Cannon53ab5b72006-06-22 16:49:14 +000036- Bug #1510580: The 'warnings' module improperly required that a Warning
37 category be either a types.ClassType and a subclass of Warning. The proper
38 check is just that it is a subclass with Warning as the documentation states.
39
Georg Brandlad29e632006-06-21 17:45:17 +000040- The compiler module now correctly compiles the new try-except-finally
41 statement (bug #1509132).
42
Neal Norwitz60373cd2006-06-22 06:30:50 +000043- The wsgiref package is now installed properly on Unix.
44
Vinay Sajip28e57612006-07-01 10:45:20 +000045- A bug was fixed in logging.config.fileConfig() which caused a crash on
46 shutdown when fileConfig() was called multiple times.

77Core and builtins
78-----------------
79
Georg Brandla56b9152006-06-19 06:35:54 +000080- Patch #1507676: Error messages returned by invalid abstract object operations
81 (such as iterating over an integer) have been improved and now include the
82 type of the offending object to help with debugging.
83
Brett Cannonea3912b2006-06-13 21:46:41 +000084- Bug #992017: A classic class that defined a __coerce__() method that returned
85 its arguments swapped would infinitely recurse and segfault the interpreter.
86
Neal Norwitz909eb122006-06-12 02:13:21 +000087- Fix the socket tests so they can be run concurrently.
88
Neal Norwitzb9845e72006-06-12 02:11:18 +000089- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +000090 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +000091
Brett Cannon22565aa2006-06-09 22:31:23 +000092- Bug #532646: object.__call__() will continue looking for the __call__
93 attribute on objects until one without one is found. This leads to recursion
94 when you take a class and set its __call__ attribute to an instance of the
95 class. Originally fixed for classic classes, but this fix is for new-style.
96 Removes the infinite_rec_3 crasher.
97
Georg Brandl24250812006-06-09 18:45:48 +000098- The string and unicode methods startswith() and endswith() now accept
99 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
100
Brett Cannonde3b0522006-06-08 17:00:45 +0000101- Buffer objects, at the C level, never used the char buffer
102 implementation even when the char buffer for the wrapped object was
103 explicitly requested (originally returned the read or write buffer).
104 Now a TypeError is raised if the char buffer is not present but is
105 requested.
106
Georg Brandlddbaa662006-06-04 21:56:52 +0000107- Patch #1346214: Statements like "if 0: suite" are now again optimized
108 away like they were in Python 2.4.
109
Georg Brandlb7c8f542006-05-27 12:30:25 +0000110- Builtin exceptions are now full-blown new-style classes instead of
111 instances pretending to be classes, which speeds up exception handling
112 by about 80% in comparison to 2.5a2.
113
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000114- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
115 Unicode 4.1.
116
Georg Brandlf4ef1162006-05-26 18:03:31 +0000117- Patch #921466: sys.path_importer_cache is now used to cache valid and
118 invalid file paths for the built-in import machinery which leads to
119 fewer open calls on startup.
120
Tim Peters696cf432006-05-24 21:10:40 +0000121- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
122 of-2 bases. The largest speedup is for inputs with about 1000 decimal
123 digits. Conversion from non-power-of-2 bases remains quadratic-time in
124 the number of input digits (it was and remains linear-time for bases
125 2, 4, 8, 16 and 32).
126
Tim Petersb713ec22006-05-23 18:45:30 +0000127- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
128 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
129 an integer close to ``sys.maxint``. This was repaired by patch
130 #1335972, which also gives a nice speedup.
131
Richard Jonescebbefc2006-05-23 18:28:17 +0000132- Patch #1337051: reduced size of frame objects.
133
134- PyErr_NewException now accepts a tuple of base classes as its
135 "base" parameter.
136
Richard Jones7c88dcc2006-05-23 10:37:38 +0000137- Patch #876206: function call speedup by retaining allocated frame
138 objects.
139
Georg Brandl7b90e162006-05-18 07:01:27 +0000140- Bug #1462152: file() now checks more thoroughly for invalid mode
141 strings and removes a possible "U" before passing the mode to the
142 C library function.
143
Neal Norwitz1004a532006-05-15 07:17:23 +0000144- Patch #1488312, Fix memory alignment problem on SPARC in unicode
145
Neal Norwitz373f0a72006-05-15 07:04:36 +0000146- Bug #1487966: Fix SystemError with conditional expression in assignment
147
Martin v. Löwis879768d2006-05-11 13:28:43 +0000148- WindowsError now has two error code attributes: errno, which carries
149 the error values from errno.h, and winerror, which carries the error
150 values from winerror.h. Previous versions put the winerror.h values
151 (from GetLastError()) into the errno attribute.
152
Martin v. Löwis77736712006-05-04 05:51:03 +0000153- Patch #1475845: Raise IndentationError for unexpected indent.
154
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000155- Patch #1479181: split open() and file() from being aliases for each other.
156
Tim Peters44bd9862006-06-01 13:49:23 +0000157- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
158 methods were always silently ignored by dictionaries when comparing keys.
159 They are now passed through (except when using the C API function
160 ``PyDict_GetItem()``, whose semantics did not change).
161
162- Bug #1456209: In some obscure cases it was possible for a class with a
163 custom ``__eq__()`` method to confuse dict internals when class instances
164 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
165 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +0000170- Bug #1295808: expat symbols should be namespaced in pyexpat
171
172- Patch #1462338: Upgrade pyexpat to expat 2.0.0
173
Brett Cannon6ee7d012006-06-08 16:23:04 +0000174- Change binascii.hexlify to accept a read-only buffer instead of only a char
175 buffer and actually follow its documentation.
176
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000177- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
178
Nick Coghlanc649ec52006-05-29 12:43:05 +0000179- Patch #1478788 (modified version): The functional extension module has
180 been renamed to _functools and a functools Python wrapper module added.
181 This provides a home for additional function related utilities that are
182 not specifically about functional programming. See PEP 309.
183
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000184- Patch #1493701: performance enhancements for struct module.
185
Georg Brandl378d5922006-05-17 14:26:50 +0000186- Patch #1490224: time.altzone is now set correctly on Cygwin.
187
Georg Brandl8d3342b2006-05-16 07:38:27 +0000188- Patch #1435422: zlib's compress and decompress objects now have a
189 copy() method.
190
Andrew MacIntyre92913322006-06-13 15:04:24 +0000191- Patch #1454481: thread stack size is now tunable at runtime for thread
192 enabled builds on Windows and systems with Posix threads support.
193
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000194- On Win32, os.listdir now supports arbitrarily-long Unicode path names
195 (up to the system limit of 32K characters).
196
197- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
198 As a result, these functions now raise WindowsError instead of OSError.
199
Tim Peters7a822da2006-05-25 21:50:17 +0000200- ``time.clock()`` on Win64 should use the high-performance Windows
201 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
202 Windows platforms).
203
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000204- Calling Tk_Init twice is refused if the first call failed as that
205 may deadlock.
206
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000207- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
208 accept it without potentially using an uninitialized pointer.
209
210- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
211 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
212 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000213
Gregory P. Smith372b5832006-06-05 18:48:21 +0000214- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000215 [pybsddb project SF patch number 1466734]
216
Gregory P. Smith372b5832006-06-05 18:48:21 +0000217- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
218 parameter is supplied. [SF pybsddb bug #1477863]
219
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000220- bsddb: the __len__ method of a DB object has been fixed to return correct
221 results. It could previously incorrectly return 0 in some cases.
222 Fixes SF bug 1493322 (pybsddb bug 1184012).
223
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000224- bsddb: the bsddb.dbtables Modify method now raises the proper error and
225 aborts the db transaction safely when a modifier callback fails.
226 Fixes SF python patch/bug #1408584.
227
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000228- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000229 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000230 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
231 database calls that would previously deadlock. [SF python bug #775414]
232
Vinay Sajip28e57612006-07-01 10:45:20 +0000233- Patch #1446489: add support for the ZIP64 extensions to zipfile.

240
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000241- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
242 functions.
243
Martin v. Löwis3798da02006-06-17 18:44:27 +0000244- Patch #812986: Update turtle output even if not tracing.

248
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000249- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
250
Martin v. Löwis337487e2006-06-17 09:15:14 +0000251- Patch #763580: Add name and value arguments to Tkinter variable
252 classes.
253
Georg Brandl83cc0d02006-06-14 08:50:03 +0000254- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
255 mime.types file for determining MIME types.
256
Georg Brandl2605ca82006-06-14 06:08:31 +0000257- Bug #1339007: Shelf objects now don't raise an exception in their
258 __del__ method when initialization failed.
259
Martin v. Löwisd8251432006-06-14 05:21:04 +0000260- Patch #1455898: The MBCS codec now supports the incremental mode for
261 double-byte encodings.
262
Tim Peters43898b42006-06-14 04:09:25 +0000263- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
264 guarantee that adjacent triples in the return list always describe
265 non-adjacent blocks. Previously, a pair of matching blocks could end
266 up being described by multiple adjacent triples that formed a partition
267 of the matching pair.
268
Greg Ward0e0c9f42006-06-11 16:24:11 +0000269- Bug #1498146: fix optparse to handle Unicode strings in option help,
270 description, and epilog.
271
Greg Wardd1c797e2006-06-11 14:42:41 +0000272- Bug #1366250: minor optparse documentation error.

275 clarify docs.
276
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000277- The wsgiref package has been added to the standard library.
278
Nick Coghlan676725d2006-06-08 13:54:49 +0000279- The functions update_wrapper() and wraps() have been added to the functools
280 module. These make it easier to copy relevant metadata from the original
281 function when writing wrapper functions.
282
Tim Petersd6a9eef2006-06-05 01:48:21 +0000283- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
284 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000285
Martin v. Löwis3f767792006-06-04 19:36:28 +0000286- Patch #1359618: Speed up charmap encoder by using a trie structure
287 for lookup.
288
Tim Petersd609b1a2006-06-02 23:22:51 +0000289- The functions in the ``pprint`` module now sort dictionaries by key
290 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
291 if and only if its display required more than one line, although that
292 wasn't documented. The new behavior increases predictability; e.g.,
293 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
294
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000295- Patch #1497027: try HTTP digest auth before basic auth in urllib2
296 (thanks for J. J. Lee).
297
Georg Brandl2b330372006-05-28 20:23:12 +0000298- Patch #1496206: improve urllib2 handling of passwords with respect to
299 default HTTP and HTTPS ports.
300
George Yoshidaf3c65de2006-05-28 16:39:09 +0000301- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
302
Bob Ippolito7298f272006-05-23 18:43:47 +0000303- Patch #1281707: speed up gzip.readline.
304
Georg Brandlb89316f2006-05-17 15:51:16 +0000305- Patch #1180296: Two new functions were added to the locale module:
306 format_string() to get the effect of "format % items" but locale-aware,
307 and currency() to format a monetary number with currency sign.
308
Georg Brandle3a25832006-05-17 14:56:04 +0000309- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
310 and several features added, such as speed and geometry control.
311
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000312- Patch #1488881: add support for external file objects in bz2 compressed
313 tarfiles.
314
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000315- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
316 stdout arguments, making it possible to redirect input and output
317 for remote debugging.
318
319- Patch #1484695: Update the tarfile module to version 0.8. This fixes
320 a couple of issues, notably handling of long file names using the
321 GNU LONGNAME extension.
322
323- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
324 new flag when ``name`` is already the name of an option flag.
325
326- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
327 package.
328
329- Patch #1472854: make the rlcompleter.Completer class usable on non-
330 UNIX platforms.
331

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000365What's New in Python 2.5 alpha 2?
366=================================
367
368*Release date: 27-APR-2006*
369
370Core and builtins
371-----------------
372
Thomas Heller1b046642006-04-18 18:51:06 +0000373- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
374 by converting these apis from macros into exported functions again:
375
376 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
377 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
378 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
379 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
380 PyRun_String Py_CompileString
381
Martin v. Löwis45294a92006-04-18 06:24:08 +0000382- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
383
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000384- All uses of PyStructSequence_InitType have been changed to initialize
385 the type objects only once, even if the interpreter is initialized
386 multiple times.
387
Neal Norwitz61546162006-04-14 05:20:28 +0000388- Bug #1454485, array.array('u') could crash the interpreter. This was
389 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
390 to unicode when it didn't make sense. 'u#' now requires a unicode string.
391
392- Py_UNICODE is unsigned. It was always documented as unsigned, but
393 due to a bug had a signed value in previous versions.
394
Tim Peters3a5e8b12006-04-11 01:44:07 +0000395- Patch #837242: ``id()`` of any Python object always gives a positive
396 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
397 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000398 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000399 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000400
Tim Peters3a5e8b12006-04-11 01:44:07 +0000401 def __hash__(self):
402 return id(self) # WRONG
403
404 because a hash result must be a (short) Python int but it was always
405 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000406 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000407 was always usable as a hash value before this patch. That's no longer
408 necessarily so.
409
410- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000411 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000412 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000413 #1454844)
414
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000415- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
416 involving generators that have paused outside of any ``try`` or ``with``
417 blocks. (In 2.5a1, a paused generator that was part of a reference
418 cycle could not be garbage collected, regardless of whether it was
419 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000421Extension Modules
422-----------------

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000424- Patch #1191065: Fix preprocessor problems on systems where recvfrom
425 is a macro.
426
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000427- Bug #1467952: os.listdir() now correctly raises an error if readdir()
428 fails with an error condition.
429
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000430- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
431
432- Bug #1117761: bsddb.*open() no longer raises an exception when using
433 the cachesize parameter.
434
435- Bug #1149413: bsddb.*open() no longer raises an exception when using
436 a temporary db (file=None) with the 'n' flag to truncate on open.
437
438- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
439 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000440
Armin Rigoa9017c32006-04-19 11:50:27 +0000441- Patch #1062014: AF_UNIX sockets under Linux have a special
442 abstract namespace that is now fully supported.
443
Anthony Baxter51bcb682006-04-05 14:51:42 +0000444Library
445-------
446
Tim Peters711bf302006-04-25 03:31:36 +0000447- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
448 a doctest to be skipped (the code is not run, and the expected output
449 or exception is ignored).
450
Nick Coghlanda2268f2006-04-24 04:37:15 +0000451- Fixed contextlib.nested to cope with exceptions being raised and
452 caught inside exit handlers.
453
Greg Wardab05edc2006-04-23 03:47:58 +0000454- Updated optparse module to Optik 1.5.1 (allow numeric constants in
455 hex, octal, or binary; add ``append_const`` action; keep going if
456 gettext cannot be imported; added ``OptionParser.destroy()`` method;
457 added ``epilog`` for better help generation).
458
Tim Peters21fbd572006-04-21 21:18:10 +0000459- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
460 called from a thread spawned as a side effect of importing a module.
461
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000462- The pydoc module now supports documenting packages contained in
463 .zip or .egg files.
464
465- The pkgutil module now has several new utility functions, such
466 as ``walk_packages()`` to support working with packages that are either
467 in the filesystem or zip files.
468
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000469- The mailbox module can now modify and delete messages from
470 mailboxes, in addition to simply reading them. Thanks to Gregory
471 K. Johnson for writing the code, and to the 2005 Google Summer of
472 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000473
Tim Petersc7605f22006-04-17 21:12:33 +0000474- The ``__del__`` method of class ``local`` in module ``_threading_local``
475 returned before accomplishing any of its intended cleanup.
476
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000477- Patch #790710: Add breakpoint command lists in pdb.
478
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000479- Patch #1063914: Add Tkinter.Misc.clipboard_get().
480
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000481- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
482
Anthony Baxtere29002c2006-04-12 12:07:31 +0000483- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
484 Windows. Bug #1469163.
485
Phillip J. Eby47032112006-04-11 01:07:43 +0000486- The warnings, linecache, inspect, traceback, site, and doctest modules
487 were updated to work correctly with modules imported from zipfiles or
488 via other PEP 302 __loader__ objects.
489
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000490- Patch #1467770: Reduce usage of subprocess._active to processes which
491 the application hasn't waited on.
492
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000493- Patch #1462222: Fix Tix.Grid.
494
Neal Norwitza31bf182006-04-09 03:35:43 +0000495- Fix exception when doing glob.glob('anything*/')
496
Skip Montanaro262fb922006-04-21 02:31:07 +0000497- The pstats.Stats class accepts an optional stream keyword argument to
498 direct output to an alternate file-like object.
499

501-----
502
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000503- The Makefile now has a reindent target, which runs reindent.py on
504 the library.
505
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000506- Patch #1470875: Building Python with MS Free Compiler
507
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000508- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000509
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000510- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
511 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000512 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000513 CXX from --with-cxx-main, see description in README.
514
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000515- Patch #1429775: Link extension modules with the shared libpython.
516
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000517- Fixed a libffi build problem on MIPS systems.
518
Tim Peters8931ff12006-05-13 23:28:20 +0000519- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
520 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
521 and "%zu" for unsigned integers of type ``size_t``.
522

524-----
525
Nick Coghlanda2268f2006-04-24 04:37:15 +0000526- test_contextlib now checks contextlib.nested can cope with exceptions
527 being raised and caught inside exit handlers.
528
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000529- test_cmd_line now checks operation of the -m and -c command switches
530
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000531- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
532 it separately and by hand. It also wasn't cleaning up its changes to
533 the current Decimal context.
534
Thomas Woutersabd08882006-04-26 15:53:30 +0000535- regrtest.py now has a -M option to run tests that test the new limits of
536 containers, on 64-bit architectures. Running these tests is only sensible
537 on 64-bit machines with more than two gigabytes of memory. The argument
538 passed is the maximum amount of memory for the tests to use.

547-------------
548
Tim Petersb06d28c2006-05-12 01:57:59 +0000549- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
550
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000551- PEP 343: Added Context Types section to the library reference
552 and attempted to bring other PEP 343 related documentation into
553 line with the implementation and/or python-dev discussions.
554
Tim Peters8dc73d22006-04-24 02:03:16 +0000555- Bug #1337990: clarified that ``doctest`` does not support examples
556 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000559What's New in Python 2.5 alpha 1?
560=================================
561
Anthony Baxterebed3f62006-04-03 15:03:44 +0000562*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000563
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000564Core and builtins
565-----------------
566
Nick Coghlan43832302006-04-23 17:04:07 +0000567- PEP 338: -m command line switch now delegates to runpy.run_module
568 allowing it to support modules in packages and zipfiles
569
Martin v. Löwisc661b882006-04-20 04:54:23 +0000570- On Windows, .DLL is not an accepted file name extension for
571 extension modules anymore; extensions are only found if they
572 end in .PYD.
573
Martin v. Löwisea62d252006-04-03 10:56:49 +0000574- Bug #1421664: sys.stderr.encoding is now set to the same value as
575 sys.stdout.encoding.
576
Neal Norwitz92e212f2006-04-03 04:48:37 +0000577- __import__ accepts keyword arguments.
578
Georg Brandlccadf842006-03-31 18:54:53 +0000579- Patch #1460496: round() now accepts keyword arguments.
580
Anthony Baxter262c00a2006-03-30 10:53:17 +0000581- Fixed bug #1459029 - unicode reprs were double-escaped.
582
Hye-Shik Changd478f342006-03-23 12:32:36 +0000583- Patch #1396919: The system scope threads are reenabled on FreeBSD
584 5.4 and later versions.
585
Neal Norwitze98ccf62006-03-23 05:39:47 +0000586- Bug #1115379: Compiling a Unicode string with an encoding declaration
587 now gives a SyntaxError.
588
Georg Brandlabd1ff82006-03-18 07:59:59 +0000589- Previously, Python code had no easy way to access the contents of a
590 cell object. Now, a ``cell_contents`` attribute has been added
591 (closes patch #1170323).
592
Tim Peterscf79aac2006-03-16 01:14:46 +0000593- Patch #1123430: Python's small-object allocator now returns an arena to
594 the system ``free()`` when all memory within an arena becomes unused
595 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
596 freed. Some applications will see a drop in virtual memory size now,
597 especially long-running applications that, from time to time, temporarily
598 use a large number of small objects. Note that when Python returns an
599 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000600 platform C library will in turn return that memory to the operating system.
601 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000602 appears to be effective at least on Microsoft C and gcc-based systems.
603 Thanks to Evan Jones for hard work and patience.
604
Georg Brandl533ff6f2006-03-08 18:09:27 +0000605- Patch #1434038: property() now uses the getter's docstring if there is
606 no "doc" argument given. This makes it possible to legitimately use
607 property() as a decorator to produce a read-only property.
608
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000609- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
610 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
611 of requiring an int or long in slicing and a few other contexts, enabling
612 other objects (e.g. Numeric Python's integers) to be used as slice indices.
613
Neal Norwitz995acdf2006-03-07 05:01:00 +0000614- Fixed various bugs reported by Coverity's Prevent tool.
615
Brett Cannonbf364092006-03-01 04:25:17 +0000616- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
617 new exception base class, BaseException, which has a new message attribute.
618 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
619 Raising a string exception now raises a DeprecationWarning.
620
Thomas Woutersfb609f42006-02-28 16:37:25 +0000621- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
622 explicitly relative, using 'from .module import name' to mean 'from the same
623 package as this module is in. Imports without dots still default to the
624 old relative-then-absolute, unless 'from __future__ import
625 absolute_import' is used.
626
Brett Cannona7446e32006-02-27 23:39:10 +0000627- Properly check if 'warnings' raises an exception (usually when a filter set
628 to "error" is triggered) when raising a warning for raising string
629 exceptions.
630
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000631- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000632 The name was removed from Include/code.h.
633
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000634- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000635
Guido van Rossum1968ad32006-02-25 22:38:04 +0000636- Patch 1433928:
637 - The copy module now "copies" function objects (as atomic objects).
638 - dict.__getitem__ now looks for a __missing__ hook before raising
639 KeyError.
640
Tim Peters84ef21c2006-02-28 20:39:06 +0000641- PEP 343: with statement implemented. Needs ``from __future__ import
642 with_statement``. Use of 'with' as a variable will generate a warning.
643 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000644 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000645 The following objects have __context__ methods:
646 - The built-in file type.
647 - The thread.LockType type.
648 - The following types defined by the threading module:
649 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
650 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000651
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000652- Fix the encodings package codec search function to only search
653 inside its own package. Fixes problem reported in patch #1433198.
654
655 Note: Codec packages should implement and register their own
656 codec search function. PEP 100 has the details.
657
Tim Peters9ea89d22006-06-04 03:26:02 +0000658- PEP 353: Using ``Py_ssize_t`` as the index type.
659
660- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
661 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
662 now allow Python to make use of memory blocks exceeding 2**32 bytes for
663 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
664 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000665
Neal Norwitzfc76d632006-01-10 06:03:13 +0000666- Patch #1400181, fix unicode string formatting to not use the locale.
667 This is how string objects work. u'%f' could use , instead of .
668 for the decimal point. Now both strings and unicode always use periods.
669
Neal Norwitz671b9e32006-01-09 07:07:12 +0000670- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
671 configure would break checking curses.h.
672
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000673- Bug #959576: The pwd module is now builtin. This allows Python to be
674 built on UNIX platforms without $HOME set.
675
Neal Norwitzc10978f2005-12-19 06:07:16 +0000676- Bug #1072182, fix some potential problems if characters are signed.
677
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000678- Bug #889500, fix line number on SyntaxWarning for global declarations.
679
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000680- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
681
Neal Norwitze7214a12005-12-18 05:03:17 +0000682- Support for converting hex strings to floats no longer works.
683 This was not portable. float('0x3') now raises a ValueError.
684
Barry Warsaw2a38a862005-12-18 01:27:35 +0000685- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000686 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000687 is now displayed in interactive prompt banner.
688
Georg Brandlfa166682005-12-17 21:45:17 +0000689- Implementation of PEP 341 - Unification of try/except and try/finally.
690 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000691 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000692
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000693- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
694 now encodes backslash correctly.
695
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000696- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
697
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000698- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000699 and long longs.
700
Neal Norwitz67715f02005-11-09 06:59:35 +0000701- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000702 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000703 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000704
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000705- Replaced most Unicode charmap codecs with new ones using the
706 new Unicode translate string feature in the builtin charmap
707 codec; the codecs were created from the mapping tables available
708 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
709 encodings now include a mapping for the Apple logo)
710
Tim Peterse3547fd2005-12-16 23:13:57 +0000711- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000712
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000713- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000714
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000715- A new AST parser implementation was completed. The abstract
716 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000717 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000718
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000719- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000720 The following code now raises a SyntaxError: foo(a = i for i in range(10))
721
Neal Norwitz708e51a2005-10-03 04:48:15 +0000722- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
723
Neal Norwitz11bd1192005-10-03 00:54:56 +0000724- SF Bug #887946: fix segfault when redirecting stdin from a directory.
725 Provide a warning when a directory is passed on the command line.
726
Neal Norwitz40d37812005-10-02 01:48:49 +0000727- Fix segfault with invalid coding.
728
729- SF bug #772896: unknown encoding results in MemoryError.
730
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000731- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000732 supported a __len__() method which evaluated to False when the iterator
733 was empty.
734
Guido van Rossum630db602005-09-20 18:49:54 +0000735- On 64-bit platforms, when __len__() returns a value that cannot be
736 represented as a C int, raise OverflowError.
737
Skip Montanarof8948ca2005-09-19 03:54:46 +0000738- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000739 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000740
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000741- SF bug #893549: parsing keyword arguments was broken with a few format
742 codes.
743
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000744- Changes donated by Elemental Security to make it work on AIX 5.3
745 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
746 bug #105470: test_pwd fails on 64bit system (Opteron).
747
Guido van Rossum539c6622005-09-14 17:49:54 +0000748- Changes donated by Elemental Security to make it work on HP-UX 11 on
749 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
750
Georg Brandl4550b8d2005-08-26 06:43:52 +0000751- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000752 (fixes bug #1119418).
753
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000754- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
755
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000756- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
757 exceptions that cause a function to exit.
758
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000759- The implementation of set() and frozenset() was revised to use its
760 own internal data structure. Memory consumption is reduced by 1/3
761 and there are modest speed-ups as well. The API is unchanged.
762
Tim Petersde7990b2005-07-17 23:45:23 +0000763- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
764
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000765- SF bug #1229429: PyObject_CallMethod failed to decrement some
766 reference counts in some error exit cases.
767
Tim Petersecc6e6a2005-07-10 22:30:55 +0000768- SF bug #1185883: Python's small-object memory allocator took over
769 a block managed by the platform C library whenever a realloc specified
770 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000771 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000772 portable way to copy data from the C-managed block into Python's
773 small-object space without risking a memory fault. Python's small-object
774 realloc now leaves such blocks under the control of the platform C
775 realloc.
776
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000777- SF bug #1232517: An overflow error was not detected properly when
778 attempting to convert a large float to an int in os.utime().
779
Raymond Hettinger3296e692005-06-29 23:29:56 +0000780- SF bug #1224347: hex longs now print with lowercase letters just
781 like their int counterparts.
782
Michael W. Hudson188d4362005-06-20 16:52:57 +0000783- SF bug #1163563: the original fix for bug #1010677 ("thread Module
784 Breaks PyGILState_Ensure()") broke badly in the case of multiple
785 interpreter states; back out that fix and do a better job (see
786 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
787 for a longer write-up of the problem).
788
Michael W. Hudsondf888462005-06-03 14:41:55 +0000789- SF patch #1180995: marshal now uses a binary format by default when
790 serializing floats.
791
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000792- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
793 the routines that promise to produce IEEE 754 binary representations
794 of floats now simply copy bytes around.
795
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000796- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
797 278.
798
Brett Cannonc3647ac2005-04-26 03:45:26 +0000799- patch #1109424: int, long, float, complex, and unicode now check for the
800 proper magic slot for type conversions when subclassed. Previously the
801 magic slot was ignored during conversion. Semantics now match the way
802 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000803 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000804 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000805 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000806
Barry Warsawc8d907c2005-04-19 23:43:40 +0000807- Descriptors defined in C with a PyGetSetDef structure, where the setter is
808 NULL, now raise an AttributeError when attempting to set or delete the
809 attribute. Previously a TypeError was raised, but this was inconsistent
810 with the equivalent pure-Python implementation.
811
Michael W. Hudson774479c2005-04-18 08:46:17 +0000812- It is now safe to call PyGILState_Release() before
813 PyEval_InitThreads() (note that if there is reason to believe there
814 are multiple threads around you still must call PyEval_InitThreads()
815 before using the Python API; this fix is for extension modules that
816 have no way of knowing if Python is multi-threaded yet).
817
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000818- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
819 disabled caused a crash.
820
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000821- Bug #1165306: instancemethod_new allowed the creation of a method
822 with im_class == im_self == NULL, which caused a crash when called.
823
Tim Petersecc6e6a2005-07-10 22:30:55 +0000824- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000825 fixes the crash seen in bug #1165761
826
Raymond Hettinger96229b12005-03-11 06:49:40 +0000827- Added two new builtins, any() and all().
828
Brett Cannon409d8f22005-03-05 06:47:57 +0000829- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000830 (e.g., ``class C(): pass`` is no longer a syntax error).
831 Patch #1176012 added support to the 'parser' module and 'compiler' package
832 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000833
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000834- Patch #1115086: Support PY_LONGLONG in structmember.
835
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000836- Bug #1155938: new style classes did not check that __init__() was
837 returning None.
838
Tim Petersecc6e6a2005-07-10 22:30:55 +0000839- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000840 ('\') with a specific error message.
841
Martin v. Löwisff232d72005-03-03 09:24:38 +0000842- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
843
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000844- Bug #1124295: the __name__ attribute of file objects was
845 inadvertently made inaccessible in restricted mode.
846
Tim Petersecc6e6a2005-07-10 22:30:55 +0000847- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000848 an ferror() call.
849
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000850- min() and max() now support key= arguments with the same meaning as in
851 list.sort().
852
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000853- The peephole optimizer now performs simple constant folding in expressions:
854 (2+3) --> (5).
855
Raymond Hettingera422c342005-01-11 03:03:27 +0000856- set and frozenset objects can now be marshalled. SF #1098985.
857
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000858- Bug #1077106: Poor argument checking could cause memory corruption
859 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000860
Jeremy Hyltonab630502005-02-04 18:44:06 +0000861- The parser did not complain about future statements in illegal
862 positions. It once again reports a syntax error if a future
863 statement occurs after anything other than a doc string.
864
Neil Schemenauercf52c072005-08-12 17:34:58 +0000865- Change the %s format specifier for str objects so that it returns a
866 unicode instance if the argument is not an instance of basestring and
867 calling __str__ on the argument returns a unicode instance.
868
Tim Petersf4e69282006-02-27 17:15:31 +0000869- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
870 current thread state when the auto-GIL-state machinery knows about
871 it (since the thread state is being deleted, continuing to remember it
872 can't help, but can hurt if another thread happens to get created with
873 the same thread id).
874
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000875Extension Modules
876-----------------
877
Georg Brandl43f08a82006-03-31 18:01:16 +0000878- Patch #1380952: fix SSL objects timing out on consecutive read()s
879
Neal Norwitz05a45592006-03-20 06:30:08 +0000880- Patch #1309579: wait3 and wait4 were added to the posix module.
881
Anthony Baxterfa869072006-03-20 05:21:58 +0000882- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
883 In addition, the existing ulaw code was updated.
884
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000885- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000886 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000887
Neal Norwitz10be10c2006-03-16 06:50:13 +0000888- Everything under lib-old was removed. This includes the following modules:
889 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000890 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000891 util, whatsound, whrandom, zmod
892
893- The following modules were removed: regsub, reconvert, regex, regex_syntax.
894
895- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000896 is deprecated. The undocumented re.engine variable no longer exists.
897
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000898- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
899 SS2 (single-shift 2) escape sequences correctly.
900

1063-------
1064
Nick Coghlan43832302006-04-23 17:04:07 +00001065- PEP 338: new module runpy defines a run_module function to support
1066 executing modules which provide access to source code or a code object
1067 via the PEP 302 import mechanisms.
1068
Anthony Baxter93f5b932006-04-03 08:05:07 +00001069- The email module's parsedate_tz function now sets the daylight savings

1077 in attribute values.
1078
Anthony Baxterc51ee692006-04-01 00:57:31 +00001079- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001080 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001081 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001082 module will not be built.
1083
Tim Petersc17976e2006-04-01 00:26:53 +00001084- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1085 aren't officially supported here, and trying to use them will probably
1086 raise an exception some day. But dicts have been allowed, and "mostly
1087 worked", so support for them won't go away without warning.
1088
Georg Brandl338ef7d2006-03-31 18:42:16 +00001089- Bug #1445068: getpass.getpass() can now be given an explicit stream

1107
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001108- email 4.0 package now integrated. This is largely the same as the email 3.0
1109 package that was included in Python 2.3, except that PEP 8 module names are
1110 now used (e.g. mail.message instead of email.Message). The MIME classes
1111 have been moved to a subpackage (e.g. email.mime.text instead of
1112 email.MIMEText). The old names are still supported for now. Several
1113 deprecated Message methods have been removed and lots of bugs have been
1114 fixed. More details can be found in the email package documentation.
1115
Walter Dörwald40108c92006-03-27 08:15:44 +00001116- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1117 (a subclass of tuple) that provides incremental decoders and encoders
1118 (a way to use stateful codecs without the stream API). Python functions
1119 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1120 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1121 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001122
Walter Dörwald067db482006-03-15 22:17:27 +00001123- Patch #1359365: Calling next() on a closed StringIO.String object raises
1124 a ValueError instead of a StopIteration now (like file and cString.String do).
1125 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1126 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001127
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001128- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Petersda1329b2006-02-27 16:50:01 +00001175- Patch #1349118: urllib now supports user:pass@ style proxy
Martin v. Löwis3e865952006-01-24 15:51:21 +00001176 specifications, raises IOErrors when proxies for unsupported protocols
1177 are defined, and uses the https proxy on https redirections.

1194
Neal Norwitz338e7862005-12-23 21:27:46 +00001195- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1196 LoadError as documented, instead of IOError. For compatibility,
1197 LoadError subclasses IOError.
1198
Brett Cannon3cbd0382005-12-16 22:49:23 +00001199- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001200 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1201 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1202 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1203 Ronald L. Rivest offered this advice for Python:
1204
1205 "The consensus of researchers in this area (at least as
1206 expressed at the NIST Hash Function Workshop 10/31/05),
1207 is that SHA-256 is a good choice for the time being, but
1208 that research should continue, and other alternatives may
1209 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001210
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001211- Added a subset of Fredrik Lundh's ElementTree package. Available

1264 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001265 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001266

1288 to W3C name (404 -> 'Not Found'). RFE #1216944.
1289
Georg Brandl9e43acf2005-07-04 17:16:07 +00001290- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1291 as this can cause problems with apps closing all file descriptors.

1304 Bug #1224621.
1305
Raymond Hettinger68c04532005-06-10 11:05:19 +00001306- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001307 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001308 the generate_tokens() function now accepts a callable argument that
1309 terminates by raising StopIteration.
1310
Georg Brandl9166e1a2005-06-04 09:20:03 +00001311- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1326
Raymond Hettinger267b8682005-03-27 10:47:39 +00001327- decimal operator and comparison methods now return NotImplemented
1328 instead of raising a TypeError when interacting with other types. This
1329 allows other classes to implement __radd__ style methods and have them
1330 work as expected.
1331
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001332- Bug #1163325: Decimal infinities failed to hash. Attempting to
1333 hash a NaN raised an InvalidOperation instead of a TypeError.
1334
Tim Petersecc6e6a2005-07-10 22:30:55 +00001335- Patch #918101: Add tarfile open mode r|* for auto-detection of the

Guido van Rossumd0641422005-02-03 15:01:24 +00001370- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1371 disables recursive traversal through instance attributes, which can
1372 be exploited in various ways.
1373
Tim Peterse3547fd2005-12-16 23:13:57 +00001374- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001375 flags on the HTTP listening socket.
1376
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001377- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1378 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1379
Tim Peterse3547fd2005-12-16 23:13:57 +00001380- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001381 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1382

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001385- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1386
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001387- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1388
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001389- Enhancements to the csv module:
1390
1391 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001392 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001393 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001394 + Dialect parameter parsing has been re-implemented to improve error
1395 reporting.
1396 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1397 dictates.
1398 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001399 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001400 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001401 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1402 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001403 + reader now allows \r characters to be quoted (previously it only allowed
1404 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001405 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001406 + Dialect classes passed to the module are no longer instantiated by
1407 the module before being parsed (the former validation scheme required
1408 this, but the mechanism was unreliable).
1409 + The dialect registry now contains instances of the internal
1410 C-coded dialect type, rather than references to python objects.
1411 + the internal c-coded dialect type is now immutable.
1412 + register_dialect now accepts the same keyword dialect specifications
1413 as the reader and writer, allowing the user to register dialects
1414 without first creating a dialect class.
1415 + a configurable limit to the size of parsed fields has been added -
1416 previously, an unmatched quote character could result in the entire
1417 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001418 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001419 the parser field size limit (returning the former limit). The initial
1420 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001421 + A line_num attribute has been added to the reader object, which tracks
1422 the number of lines read from the source iterator. This is not
1423 the same as the number of records returned, as records can span
1424 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001425 + reader and writer objects were not being registered with the cyclic-GC.
1426 This has been fixed.
1427
Brett Cannone6539c42005-01-08 02:43:53 +00001428- _DummyThread objects in the threading module now delete self.__block that is
1429 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1430 lock primitives tend to be limited in number and thus should not be wasted on
1431 a _DummyThread object. Fixes bug #1089632.
1432

1436 (Bug #951915).
1437
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001438- locale.py now uses an updated locale alias table (built using
1439 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1440 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001441 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001442
Raymond Hettinger3557f422004-12-07 12:02:02 +00001443- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1444
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001445- the pickle module no longer accepts the deprecated None option in the
1446 args tuple returned by __reduce__().
1447
Brett Cannon84667c02004-12-07 03:25:18 +00001448- optparse now optionally imports gettext. This allows its use in setup.py.
1449
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001450- the pickle module no longer uses the deprecated bin parameter.

1457
Raymond Hettinger664347b2004-12-04 21:21:53 +00001458- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1459 extended or overridden by subclasses. Formerly, the subclassed method would
1460 be ignored by the rest of the module. (Bug #1078905).
1461
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001462- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001463 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001464
Walter Dörwald36733692004-12-22 12:50:50 +00001465- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1466 once when a size argument is given. This prevents a buffer overflow in the
1467 tokenizer with very long source lines.
1468
Barry Warsaw538561e2006-01-01 21:48:54 +00001469- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1470 immediately after creating the object, without any intervening
1471 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001472
Skip Montanaro05885812005-01-16 20:48:27 +00001473- The reconvert.quote function can now emit triple-quoted strings. The
1474 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001475
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001476- ``UserString.MutableString`` now supports negative indices in
1477 ``__setitem__`` and ``__delitem__``
1478
Greg Ward40407942005-03-05 02:53:17 +00001479- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1480 correctly.
1481
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001482- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1483 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1484 character even if the user has passed a size parameter to get a proper
1485 line ending. Remove the special handling of a "\r\n" that has been split
1486 between two lines.
1487
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001488- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1489 about illegal code points. The codec now supports PEP 293 style error
1490 handlers.
1491
Walter Dörwald78a78b02005-09-01 12:04:29 +00001492- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001493 from the input stream, so that the output is a byte string in the correct
1494 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001495
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001496- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1497 considering it exactly like a '*'.
1498
Walter Dörwald007f8df2005-10-09 19:42:27 +00001499- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1500 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001501
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001502- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1503
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001504- Patch #1413711: Certain patterns of differences were making difflib
1505 touch the recursion limit.
1506
Walter Dörwald58917a62006-03-31 15:26:22 +00001507- Bug #947906: An object oriented interface has been added to the calendar
1508 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001509 called as a script (e.g. via ``python -mcalendar``). Localized month and
1510 weekday names can be ouput (even if an exotic encoding is used) using
1511 special classes that use unicode.

1515
Neal Norwitz602d3392006-03-31 08:21:40 +00001516- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1517 by using -mieee gcc option.
1518

1520
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001521- Build support for Win64-AMD64 was added.
1522
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001523- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1524
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001525- Patch #881820: look for openpty and forkpty also in libbsd.
1526
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001527- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1528 The zlib module is now builtin on Windows.
1529
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001530- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1531
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001532- Bug #1189330: configure did not correctly determine the necessary
1533 value of LINKCC if python was built with GCC 4.0.
1534
Trent Mick8321b422005-07-26 02:29:21 +00001535- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1536 vulnerability in zlib 1.2.1 and 1.2.2.
1537
Brett Cannon08cd5982005-04-24 22:26:38 +00001538- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1539 flags that change binary compatibility. Changes were also made to
1540 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001541 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001542
Bob Ippolitoed233462005-03-29 13:47:59 +00001543- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1544 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1545 no longer exists). This configure patch makes things right.
1546
Martin v. Löwise2713be2005-03-08 15:03:08 +00001547- Bug #1158607: Build with --disable-unicode again.
1548
Brett Cannon46d96232005-02-16 00:07:19 +00001549- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1550 defined. Discovered as a result of not being able to build on OS X.
1551
Brett Cannon516592f2004-12-07 00:42:59 +00001552- setup.py now uses the directories specified in LDFLAGS using the -L option
1553 and in CPPFLAGS using the -I option for adding library and include
1554 directories, respectively, for compiling extension modules against. This has
1555 led to the core being compiled using the values in CPPFLAGS. It also removes
1556 the need for the special-casing of both DarwinPorts and Fink for darwin since
1557 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1558 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1559 Fink, ``-I/opt/local/include`` for DarwinPorts).
1560
Brett Cannon43802422005-02-10 20:48:03 +00001561- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1562 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1563 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1564 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001566C API
1567-----
1568
Tim Petersc9d78aa2006-03-26 23:27:58 +00001569- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1570 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1571 is obtained via the ``PyObject_`` family, it must be released via the
1572 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1573 always been officially true, but when Python's small-object allocator was
1574 introduced, an attempt was made to cater to a few extension modules
1575 discovered at the time that obtained memory via ``PyObject_New`` but
1576 released it via ``PyMem_DEL``. It's years later, and if such code still
1577 exists it will fail now (probably with segfaults, but calling wrong
1578 low-level memory management functions can yield many symptoms).
1579
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001580- Added a C API for set and frozenset objects.
1581
Raymond Hettinger66517482004-12-03 11:45:13 +00001582- Removed PyRange_New().
1583
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001584- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1585 mapping argument now. This string is used as a mapping table. Byte values
1586 greater than the length of the string and 0xFFFE are treated as undefined
1587 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001594
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001595- Patch #1276356: New resource "urlfetch" is implemented. This enables
