13-----------------
14
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000015- Bug #927248: Recursive method-wrapper objects can now safely
16 be released.
17
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000018- Bug #1417699: Reject locale-specific decimal point in float()
19 and atof().
20
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000021- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
22 omit a default "error" argument for NULL pointer. This allows
23 the parser to take a codec from cjkcodecs again.

31
Thomas Heller5becdbe2006-07-06 08:48:35 +000032- Patch #1517790: It is now possible to use custom objects in the ctypes
33 foreign function argtypes sequence as long as they provide a from_param
34 method, no longer is it required that the object is a ctypes type.
35
Thomas Woutersadd19112006-07-05 11:03:49 +000036- string.Template() now correctly handles tuple-values. Previously,
37 multi-value tuples would raise an exception and single-value tuples would
38 be treated as the value they contain, instead.
39
Martin v. Löwisede77f52006-07-03 13:01:35 +000040- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

47 degrees and radians.
48
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000049- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +000050 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000051
Martin v. Löwisbd39c032006-07-03 09:44:00 +000052- Bug #1514703: Only setup canvas window in turtle when the canvas
53 is created.
54
Martin v. Löwis7596e832006-07-01 15:33:37 +000055- Bug #1513223: .close() of a _socketobj now releases the underlying
56 socket again, which then gets closed as it becomes unreferenced.
57
Thomas Hellerbde08132006-06-29 18:34:15 +000058- The '_ctypes' extension module now works when Python is configured
59 with the --without-threads option.
60
Fred Drake10497c82006-06-29 02:57:48 +000061- Bug #1504333: Make sgmllib support angle brackets in quoted
62 attribute values.
63
64- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
65 sgmllib ('[' and ']' were not accepted).
66
Georg Brandl1be63af2006-06-28 20:23:25 +000067- Fix a bug in the turtle module's end_fill function.
68
Brett Cannon53ab5b72006-06-22 16:49:14 +000069- Bug #1510580: The 'warnings' module improperly required that a Warning
70 category be either a types.ClassType and a subclass of Warning. The proper
71 check is just that it is a subclass with Warning as the documentation states.
72
Georg Brandlad29e632006-06-21 17:45:17 +000073- The compiler module now correctly compiles the new try-except-finally
74 statement (bug #1509132).
75
Neal Norwitz60373cd2006-06-22 06:30:50 +000076- The wsgiref package is now installed properly on Unix.
77
Vinay Sajip28e57612006-07-01 10:45:20 +000078- A bug was fixed in logging.config.fileConfig() which caused a crash on
79 shutdown when fileConfig() was called multiple times.
80
Gerhard Häring762fbd32006-07-02 17:48:30 +000081- The sqlite3 module did cut off data from the SQLite database at the first
82 null character before sending it to a custom converter. This has been fixed
83 now.
84
Neal Norwitz0f8b31a2006-06-28 06:28:31 +000085Extension Modules
86-----------------
87
Martin v. Löwisee1e06d2006-07-02 18:44:00 +000088- Bug #1513646: os.access on Windows now correctly determines write
89 access, again.
90
Neal Norwitz0f8b31a2006-06-28 06:28:31 +000091- Bug #1512695: cPickle.loads could crash if it was interrupted with
92 a KeyboardInterrupt.
93
Neal Norwitza12aa882006-07-06 06:45:08 +000094- Bug #1296433: parsing XML with a non-default encoding and
95 a CharacterDataHandler could crash the interpreter in pyexpat.
96
Neal Norwitz3b6b8012006-06-27 04:12:58 +000097Build
98-----
99
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000100- 'configure' now detects the zlib library the same way as distutils.
101 Previously, the slight difference could cause compilation errors of the
102 'zlib' module on systems with more than one version of zlib.
103
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000104- The MSI compileall step was fixed to also support a TARGETDIR
105 with spaces in it.
106
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000107- Bug #1517388: sqlite3.dll is now installed on Windows independent
108 of Tcl/Tk.
109
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000110- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000111 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000113Tests
114-----
115
116- Call os.waitpid() at the end of tests that spawn child processes in order
117 to minimize resources (zombies).
118
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000119Documentation
120-------------
121
Nick Coghlan2d792252006-07-06 13:47:18 +0000122- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
123 documentation for the warnings module.
124
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000125- Patch #1509163: MS Toolkit Compiler no longer available.

133Core and builtins
134-----------------
135
Georg Brandla56b9152006-06-19 06:35:54 +0000136- Patch #1507676: Error messages returned by invalid abstract object operations
137 (such as iterating over an integer) have been improved and now include the
138 type of the offending object to help with debugging.
139
Brett Cannonea3912b2006-06-13 21:46:41 +0000140- Bug #992017: A classic class that defined a __coerce__() method that returned
141 its arguments swapped would infinitely recurse and segfault the interpreter.
142
Neal Norwitz909eb122006-06-12 02:13:21 +0000143- Fix the socket tests so they can be run concurrently.
144
Neal Norwitzb9845e72006-06-12 02:11:18 +0000145- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000146 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000147
Brett Cannon22565aa2006-06-09 22:31:23 +0000148- Bug #532646: object.__call__() will continue looking for the __call__
149 attribute on objects until one without one is found. This leads to recursion
150 when you take a class and set its __call__ attribute to an instance of the
151 class. Originally fixed for classic classes, but this fix is for new-style.
152 Removes the infinite_rec_3 crasher.
153
Georg Brandl24250812006-06-09 18:45:48 +0000154- The string and unicode methods startswith() and endswith() now accept
155 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
156
Brett Cannonde3b0522006-06-08 17:00:45 +0000157- Buffer objects, at the C level, never used the char buffer
158 implementation even when the char buffer for the wrapped object was
159 explicitly requested (originally returned the read or write buffer).
160 Now a TypeError is raised if the char buffer is not present but is
161 requested.
162
Georg Brandlddbaa662006-06-04 21:56:52 +0000163- Patch #1346214: Statements like "if 0: suite" are now again optimized
164 away like they were in Python 2.4.
165
Georg Brandlb7c8f542006-05-27 12:30:25 +0000166- Builtin exceptions are now full-blown new-style classes instead of
167 instances pretending to be classes, which speeds up exception handling
168 by about 80% in comparison to 2.5a2.
169
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000170- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
171 Unicode 4.1.
172
Georg Brandlf4ef1162006-05-26 18:03:31 +0000173- Patch #921466: sys.path_importer_cache is now used to cache valid and
174 invalid file paths for the built-in import machinery which leads to
175 fewer open calls on startup.
176
Tim Peters696cf432006-05-24 21:10:40 +0000177- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
178 of-2 bases. The largest speedup is for inputs with about 1000 decimal
179 digits. Conversion from non-power-of-2 bases remains quadratic-time in
180 the number of input digits (it was and remains linear-time for bases
181 2, 4, 8, 16 and 32).
182
Tim Petersb713ec22006-05-23 18:45:30 +0000183- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
184 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
185 an integer close to ``sys.maxint``. This was repaired by patch
186 #1335972, which also gives a nice speedup.
187
Richard Jonescebbefc2006-05-23 18:28:17 +0000188- Patch #1337051: reduced size of frame objects.
189
190- PyErr_NewException now accepts a tuple of base classes as its
191 "base" parameter.
192
Richard Jones7c88dcc2006-05-23 10:37:38 +0000193- Patch #876206: function call speedup by retaining allocated frame
194 objects.
195
Georg Brandl7b90e162006-05-18 07:01:27 +0000196- Bug #1462152: file() now checks more thoroughly for invalid mode
197 strings and removes a possible "U" before passing the mode to the
198 C library function.
199
Neal Norwitz1004a532006-05-15 07:17:23 +0000200- Patch #1488312, Fix memory alignment problem on SPARC in unicode
201
Neal Norwitz373f0a72006-05-15 07:04:36 +0000202- Bug #1487966: Fix SystemError with conditional expression in assignment
203
Martin v. Löwis879768d2006-05-11 13:28:43 +0000204- WindowsError now has two error code attributes: errno, which carries
205 the error values from errno.h, and winerror, which carries the error
206 values from winerror.h. Previous versions put the winerror.h values
207 (from GetLastError()) into the errno attribute.
208
Martin v. Löwis77736712006-05-04 05:51:03 +0000209- Patch #1475845: Raise IndentationError for unexpected indent.
210
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000211- Patch #1479181: split open() and file() from being aliases for each other.
212
Tim Peters44bd9862006-06-01 13:49:23 +0000213- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
214 methods were always silently ignored by dictionaries when comparing keys.
215 They are now passed through (except when using the C API function
216 ``PyDict_GetItem()``, whose semantics did not change).
217
218- Bug #1456209: In some obscure cases it was possible for a class with a
219 custom ``__eq__()`` method to confuse dict internals when class instances
220 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
221 No, you don't have any code that did this ;-)

224-----------------
225
Trent Mick960a3f82006-06-28 20:30:41 +0000226- Bug #1295808: expat symbols should be namespaced in pyexpat
227
228- Patch #1462338: Upgrade pyexpat to expat 2.0.0
229
Brett Cannon6ee7d012006-06-08 16:23:04 +0000230- Change binascii.hexlify to accept a read-only buffer instead of only a char
231 buffer and actually follow its documentation.
232
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000233- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
234
Nick Coghlanc649ec52006-05-29 12:43:05 +0000235- Patch #1478788 (modified version): The functional extension module has
236 been renamed to _functools and a functools Python wrapper module added.
237 This provides a home for additional function related utilities that are
238 not specifically about functional programming. See PEP 309.
239
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000240- Patch #1493701: performance enhancements for struct module.
241
Georg Brandl378d5922006-05-17 14:26:50 +0000242- Patch #1490224: time.altzone is now set correctly on Cygwin.

245 copy() method.
246
Andrew MacIntyre92913322006-06-13 15:04:24 +0000247- Patch #1454481: thread stack size is now tunable at runtime for thread
248 enabled builds on Windows and systems with Posix threads support.
249
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000250- On Win32, os.listdir now supports arbitrarily-long Unicode path names
251 (up to the system limit of 32K characters).
252
253- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
254 As a result, these functions now raise WindowsError instead of OSError.
255
Tim Peters7a822da2006-05-25 21:50:17 +0000256- ``time.clock()`` on Win64 should use the high-performance Windows
257 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
258 Windows platforms).
259
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000260- Calling Tk_Init twice is refused if the first call failed as that
261 may deadlock.
262
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000263- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
264 accept it without potentially using an uninitialized pointer.
265
266- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
267 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
268 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000269
Gregory P. Smith372b5832006-06-05 18:48:21 +0000270- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.

272
Gregory P. Smith372b5832006-06-05 18:48:21 +0000273- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
274 parameter is supplied. [SF pybsddb bug #1477863]
275
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000276- bsddb: the __len__ method of a DB object has been fixed to return correct
277 results. It could previously incorrectly return 0 in some cases.
278 Fixes SF bug 1493322 (pybsddb bug 1184012).
279
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000280- bsddb: the bsddb.dbtables Modify method now raises the proper error and
281 aborts the db transaction safely when a modifier callback fails.
282 Fixes SF python patch/bug #1408584.
283
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000284- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000285 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000286 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
287 database calls that would previously deadlock. [SF python bug #775414]
288
Vinay Sajip28e57612006-07-01 10:45:20 +0000289- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Georg Brandl83cc0d02006-06-14 08:50:03 +0000310- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
311 mime.types file for determining MIME types.
312
Georg Brandl2605ca82006-06-14 06:08:31 +0000313- Bug #1339007: Shelf objects now don't raise an exception in their
314 __del__ method when initialization failed.
315
Martin v. Löwisd8251432006-06-14 05:21:04 +0000316- Patch #1455898: The MBCS codec now supports the incremental mode for
317 double-byte encodings.
318
Tim Peters43898b42006-06-14 04:09:25 +0000319- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
320 guarantee that adjacent triples in the return list always describe
321 non-adjacent blocks. Previously, a pair of matching blocks could end
322 up being described by multiple adjacent triples that formed a partition
323 of the matching pair.
324
Greg Ward0e0c9f42006-06-11 16:24:11 +0000325- Bug #1498146: fix optparse to handle Unicode strings in option help,
326 description, and epilog.
327
Greg Wardd1c797e2006-06-11 14:42:41 +0000328- Bug #1366250: minor optparse documentation error.
329
Greg Ward7f547402006-06-11 00:40:49 +0000330- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
331 clarify docs.
332
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000333- The wsgiref package has been added to the standard library.
334
Nick Coghlan676725d2006-06-08 13:54:49 +0000335- The functions update_wrapper() and wraps() have been added to the functools
336 module. These make it easier to copy relevant metadata from the original
337 function when writing wrapper functions.
338
Tim Petersd6a9eef2006-06-05 01:48:21 +0000339- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
340 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000341
Martin v. Löwis3f767792006-06-04 19:36:28 +0000342- Patch #1359618: Speed up charmap encoder by using a trie structure
343 for lookup.
344
Tim Petersd609b1a2006-06-02 23:22:51 +0000345- The functions in the ``pprint`` module now sort dictionaries by key
346 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
347 if and only if its display required more than one line, although that
348 wasn't documented. The new behavior increases predictability; e.g.,
349 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
350
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000351- Patch #1497027: try HTTP digest auth before basic auth in urllib2
352 (thanks for J. J. Lee).
353
Georg Brandl2b330372006-05-28 20:23:12 +0000354- Patch #1496206: improve urllib2 handling of passwords with respect to
355 default HTTP and HTTPS ports.
356
George Yoshidaf3c65de2006-05-28 16:39:09 +0000357- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
358
Bob Ippolito7298f272006-05-23 18:43:47 +0000359- Patch #1281707: speed up gzip.readline.
360
Georg Brandlb89316f2006-05-17 15:51:16 +0000361- Patch #1180296: Two new functions were added to the locale module:
362 format_string() to get the effect of "format % items" but locale-aware,
363 and currency() to format a monetary number with currency sign.
364
Georg Brandle3a25832006-05-17 14:56:04 +0000365- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
366 and several features added, such as speed and geometry control.
367
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000368- Patch #1488881: add support for external file objects in bz2 compressed
369 tarfiles.
370
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000371- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
372 stdout arguments, making it possible to redirect input and output
373 for remote debugging.
374
375- Patch #1484695: Update the tarfile module to version 0.8. This fixes
376 a couple of issues, notably handling of long file names using the
377 GNU LONGNAME extension.
378
379- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
380 new flag when ``name`` is already the name of an option flag.
381
382- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
383 package.
384
385- Patch #1472854: make the rlcompleter.Completer class usable on non-
386 UNIX platforms.
387
388- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
389
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000390- Bug #1472827: correctly escape newlines and tabs in attribute values in
391 the saxutils.XMLGenerator class.

402
Neal Norwitz58e28882006-05-19 07:00:58 +0000403- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
404
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000405- Patch #1471883: Add --enable-universalsdk.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000421What's New in Python 2.5 alpha 2?
422=================================
423
424*Release date: 27-APR-2006*
425
426Core and builtins
427-----------------
428
Thomas Heller1b046642006-04-18 18:51:06 +0000429- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
430 by converting these apis from macros into exported functions again:
431
432 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
433 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
434 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
435 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
436 PyRun_String Py_CompileString
437
Martin v. Löwis45294a92006-04-18 06:24:08 +0000438- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
439
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000440- All uses of PyStructSequence_InitType have been changed to initialize
441 the type objects only once, even if the interpreter is initialized
442 multiple times.
443
Neal Norwitz61546162006-04-14 05:20:28 +0000444- Bug #1454485, array.array('u') could crash the interpreter. This was
445 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
446 to unicode when it didn't make sense. 'u#' now requires a unicode string.
447
448- Py_UNICODE is unsigned. It was always documented as unsigned, but
449 due to a bug had a signed value in previous versions.
450
Tim Peters3a5e8b12006-04-11 01:44:07 +0000451- Patch #837242: ``id()`` of any Python object always gives a positive
452 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
453 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000454 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000455 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000456
Tim Peters3a5e8b12006-04-11 01:44:07 +0000457 def __hash__(self):
458 return id(self) # WRONG
459
460 because a hash result must be a (short) Python int but it was always
461 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000462 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000463 was always usable as a hash value before this patch. That's no longer
464 necessarily so.
465
466- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000467 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000468 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000469 #1454844)
470
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000471- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
472 involving generators that have paused outside of any ``try`` or ``with``
473 blocks. (In 2.5a1, a paused generator that was part of a reference
474 cycle could not be garbage collected, regardless of whether it was
475 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000477Extension Modules
478-----------------

481 is a macro.
482
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000483- Bug #1467952: os.listdir() now correctly raises an error if readdir()
484 fails with an error condition.
485
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000486- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
487
488- Bug #1117761: bsddb.*open() no longer raises an exception when using
489 the cachesize parameter.
490
491- Bug #1149413: bsddb.*open() no longer raises an exception when using
492 a temporary db (file=None) with the 'n' flag to truncate on open.
493
494- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
495 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000496
Armin Rigoa9017c32006-04-19 11:50:27 +0000497- Patch #1062014: AF_UNIX sockets under Linux have a special
498 abstract namespace that is now fully supported.
499
Anthony Baxter51bcb682006-04-05 14:51:42 +0000500Library
501-------
502
Tim Peters711bf302006-04-25 03:31:36 +0000503- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
504 a doctest to be skipped (the code is not run, and the expected output
505 or exception is ignored).
506
Nick Coghlanda2268f2006-04-24 04:37:15 +0000507- Fixed contextlib.nested to cope with exceptions being raised and
508 caught inside exit handlers.
509
Greg Wardab05edc2006-04-23 03:47:58 +0000510- Updated optparse module to Optik 1.5.1 (allow numeric constants in
511 hex, octal, or binary; add ``append_const`` action; keep going if
512 gettext cannot be imported; added ``OptionParser.destroy()`` method;
513 added ``epilog`` for better help generation).
514
Tim Peters21fbd572006-04-21 21:18:10 +0000515- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
516 called from a thread spawned as a side effect of importing a module.
517
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000518- The pydoc module now supports documenting packages contained in
519 .zip or .egg files.
520
521- The pkgutil module now has several new utility functions, such
522 as ``walk_packages()`` to support working with packages that are either
523 in the filesystem or zip files.
524
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000525- The mailbox module can now modify and delete messages from
526 mailboxes, in addition to simply reading them. Thanks to Gregory
527 K. Johnson for writing the code, and to the 2005 Google Summer of
528 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000529
Tim Petersc7605f22006-04-17 21:12:33 +0000530- The ``__del__`` method of class ``local`` in module ``_threading_local``
531 returned before accomplishing any of its intended cleanup.
532
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000533- Patch #790710: Add breakpoint command lists in pdb.
534
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000535- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000537- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
538
Anthony Baxtere29002c2006-04-12 12:07:31 +0000539- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
540 Windows. Bug #1469163.
541
Phillip J. Eby47032112006-04-11 01:07:43 +0000542- The warnings, linecache, inspect, traceback, site, and doctest modules
543 were updated to work correctly with modules imported from zipfiles or
544 via other PEP 302 __loader__ objects.
545
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000546- Patch #1467770: Reduce usage of subprocess._active to processes which
547 the application hasn't waited on.

554 direct output to an alternate file-like object.
555

558
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000559- The Makefile now has a reindent target, which runs reindent.py on
560 the library.
561

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000565
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000566- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
567 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000568 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000569 CXX from --with-cxx-main, see description in README.
570
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000571- Patch #1429775: Link extension modules with the shared libpython.

574
Tim Peters8931ff12006-05-13 23:28:20 +0000575- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
576 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
577 and "%zu" for unsigned integers of type ``size_t``.
578
Anthony Baxter51bcb682006-04-05 14:51:42 +0000579Tests
580-----
581
Nick Coghlanda2268f2006-04-24 04:37:15 +0000582- test_contextlib now checks contextlib.nested can cope with exceptions
583 being raised and caught inside exit handlers.
584
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000585- test_cmd_line now checks operation of the -m and -c command switches
586
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000587- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
588 it separately and by hand. It also wasn't cleaning up its changes to
589 the current Decimal context.
590
Thomas Woutersabd08882006-04-26 15:53:30 +0000591- regrtest.py now has a -M option to run tests that test the new limits of
592 containers, on 64-bit architectures. Running these tests is only sensible
593 on 64-bit machines with more than two gigabytes of memory. The argument
594 passed is the maximum amount of memory for the tests to use.

603-------------
604
Tim Petersb06d28c2006-05-12 01:57:59 +0000605- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
606
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000607- PEP 343: Added Context Types section to the library reference
608 and attempted to bring other PEP 343 related documentation into
609 line with the implementation and/or python-dev discussions.
610
Tim Peters8dc73d22006-04-24 02:03:16 +0000611- Bug #1337990: clarified that ``doctest`` does not support examples

622
Nick Coghlan43832302006-04-23 17:04:07 +0000623- PEP 338: -m command line switch now delegates to runpy.run_module
624 allowing it to support modules in packages and zipfiles
625
Martin v. Löwisc661b882006-04-20 04:54:23 +0000626- On Windows, .DLL is not an accepted file name extension for
627 extension modules anymore; extensions are only found if they
628 end in .PYD.
629
Martin v. Löwisea62d252006-04-03 10:56:49 +0000630- Bug #1421664: sys.stderr.encoding is now set to the same value as
631 sys.stdout.encoding.
632
Neal Norwitz92e212f2006-04-03 04:48:37 +0000633- __import__ accepts keyword arguments.
634
Georg Brandlccadf842006-03-31 18:54:53 +0000635- Patch #1460496: round() now accepts keyword arguments.
636
Anthony Baxter262c00a2006-03-30 10:53:17 +0000637- Fixed bug #1459029 - unicode reprs were double-escaped.
638
Hye-Shik Changd478f342006-03-23 12:32:36 +0000639- Patch #1396919: The system scope threads are reenabled on FreeBSD
640 5.4 and later versions.
641
Neal Norwitze98ccf62006-03-23 05:39:47 +0000642- Bug #1115379: Compiling a Unicode string with an encoding declaration
643 now gives a SyntaxError.
644
Georg Brandlabd1ff82006-03-18 07:59:59 +0000645- Previously, Python code had no easy way to access the contents of a
646 cell object. Now, a ``cell_contents`` attribute has been added
647 (closes patch #1170323).
648
Tim Peterscf79aac2006-03-16 01:14:46 +0000649- Patch #1123430: Python's small-object allocator now returns an arena to
650 the system ``free()`` when all memory within an arena becomes unused
651 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
652 freed. Some applications will see a drop in virtual memory size now,
653 especially long-running applications that, from time to time, temporarily
654 use a large number of small objects. Note that when Python returns an
655 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000656 platform C library will in turn return that memory to the operating system.
657 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000658 appears to be effective at least on Microsoft C and gcc-based systems.
659 Thanks to Evan Jones for hard work and patience.
660
Georg Brandl533ff6f2006-03-08 18:09:27 +0000661- Patch #1434038: property() now uses the getter's docstring if there is
662 no "doc" argument given. This makes it possible to legitimately use
663 property() as a decorator to produce a read-only property.
664
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000665- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
666 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
667 of requiring an int or long in slicing and a few other contexts, enabling
668 other objects (e.g. Numeric Python's integers) to be used as slice indices.
669
Neal Norwitz995acdf2006-03-07 05:01:00 +0000670- Fixed various bugs reported by Coverity's Prevent tool.
671
Brett Cannonbf364092006-03-01 04:25:17 +0000672- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
673 new exception base class, BaseException, which has a new message attribute.
674 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
675 Raising a string exception now raises a DeprecationWarning.
676
Thomas Woutersfb609f42006-02-28 16:37:25 +0000677- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
678 explicitly relative, using 'from .module import name' to mean 'from the same
679 package as this module is in. Imports without dots still default to the
680 old relative-then-absolute, unless 'from __future__ import
681 absolute_import' is used.
682
Brett Cannona7446e32006-02-27 23:39:10 +0000683- Properly check if 'warnings' raises an exception (usually when a filter set
684 to "error" is triggered) when raising a warning for raising string
685 exceptions.
686
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000687- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000688 The name was removed from Include/code.h.
689
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000690- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000691
Guido van Rossum1968ad32006-02-25 22:38:04 +0000692- Patch 1433928:
693 - The copy module now "copies" function objects (as atomic objects).
694 - dict.__getitem__ now looks for a __missing__ hook before raising
695 KeyError.
696
Tim Peters84ef21c2006-02-28 20:39:06 +0000697- PEP 343: with statement implemented. Needs ``from __future__ import
698 with_statement``. Use of 'with' as a variable will generate a warning.
699 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000700 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000701 The following objects have __context__ methods:
702 - The built-in file type.
703 - The thread.LockType type.
704 - The following types defined by the threading module:
705 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
706 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000707
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000708- Fix the encodings package codec search function to only search
709 inside its own package. Fixes problem reported in patch #1433198.
710
711 Note: Codec packages should implement and register their own
712 codec search function. PEP 100 has the details.
713
Tim Peters9ea89d22006-06-04 03:26:02 +0000714- PEP 353: Using ``Py_ssize_t`` as the index type.
715
716- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
717 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
718 now allow Python to make use of memory blocks exceeding 2**32 bytes for
719 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
720 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000721
Neal Norwitzfc76d632006-01-10 06:03:13 +0000722- Patch #1400181, fix unicode string formatting to not use the locale.
723 This is how string objects work. u'%f' could use , instead of .
724 for the decimal point. Now both strings and unicode always use periods.
725
Neal Norwitz671b9e32006-01-09 07:07:12 +0000726- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
727 configure would break checking curses.h.
728
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000729- Bug #959576: The pwd module is now builtin. This allows Python to be
730 built on UNIX platforms without $HOME set.
731
Neal Norwitzc10978f2005-12-19 06:07:16 +0000732- Bug #1072182, fix some potential problems if characters are signed.
733
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000734- Bug #889500, fix line number on SyntaxWarning for global declarations.
735
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000736- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
737
Neal Norwitze7214a12005-12-18 05:03:17 +0000738- Support for converting hex strings to floats no longer works.
739 This was not portable. float('0x3') now raises a ValueError.
740
Barry Warsaw2a38a862005-12-18 01:27:35 +0000741- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000742 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000743 is now displayed in interactive prompt banner.
744
Georg Brandlfa166682005-12-17 21:45:17 +0000745- Implementation of PEP 341 - Unification of try/except and try/finally.
746 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000747 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000748
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000749- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
750 now encodes backslash correctly.
751
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000752- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
753
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000754- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000755 and long longs.
756
Neal Norwitz67715f02005-11-09 06:59:35 +0000757- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000758 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000759 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000760
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000761- Replaced most Unicode charmap codecs with new ones using the
762 new Unicode translate string feature in the builtin charmap
763 codec; the codecs were created from the mapping tables available
764 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
765 encodings now include a mapping for the Apple logo)
766
Tim Peterse3547fd2005-12-16 23:13:57 +0000767- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000768
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000769- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000770
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000771- A new AST parser implementation was completed. The abstract
772 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000773 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000774
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000775- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000776 The following code now raises a SyntaxError: foo(a = i for i in range(10))
777
Neal Norwitz708e51a2005-10-03 04:48:15 +0000778- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
779
Neal Norwitz11bd1192005-10-03 00:54:56 +0000780- SF Bug #887946: fix segfault when redirecting stdin from a directory.
781 Provide a warning when a directory is passed on the command line.
782
Neal Norwitz40d37812005-10-02 01:48:49 +0000783- Fix segfault with invalid coding.
784
785- SF bug #772896: unknown encoding results in MemoryError.
786
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000787- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000788 supported a __len__() method which evaluated to False when the iterator
789 was empty.
790
Guido van Rossum630db602005-09-20 18:49:54 +0000791- On 64-bit platforms, when __len__() returns a value that cannot be
792 represented as a C int, raise OverflowError.
793
Skip Montanarof8948ca2005-09-19 03:54:46 +0000794- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000795 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000796
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000797- SF bug #893549: parsing keyword arguments was broken with a few format
798 codes.
799
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000800- Changes donated by Elemental Security to make it work on AIX 5.3
801 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
802 bug #105470: test_pwd fails on 64bit system (Opteron).
803
Guido van Rossum539c6622005-09-14 17:49:54 +0000804- Changes donated by Elemental Security to make it work on HP-UX 11 on
805 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
806
Georg Brandl4550b8d2005-08-26 06:43:52 +0000807- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000808 (fixes bug #1119418).
809
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000810- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
811
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000812- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
813 exceptions that cause a function to exit.
814
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000815- The implementation of set() and frozenset() was revised to use its
816 own internal data structure. Memory consumption is reduced by 1/3
817 and there are modest speed-ups as well. The API is unchanged.
818
Tim Petersde7990b2005-07-17 23:45:23 +0000819- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
820
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000821- SF bug #1229429: PyObject_CallMethod failed to decrement some
822 reference counts in some error exit cases.
823
Tim Petersecc6e6a2005-07-10 22:30:55 +0000824- SF bug #1185883: Python's small-object memory allocator took over
825 a block managed by the platform C library whenever a realloc specified
826 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000827 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000828 portable way to copy data from the C-managed block into Python's
829 small-object space without risking a memory fault. Python's small-object
830 realloc now leaves such blocks under the control of the platform C
831 realloc.
832
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000833- SF bug #1232517: An overflow error was not detected properly when
834 attempting to convert a large float to an int in os.utime().
835
Raymond Hettinger3296e692005-06-29 23:29:56 +0000836- SF bug #1224347: hex longs now print with lowercase letters just
837 like their int counterparts.
838
Michael W. Hudson188d4362005-06-20 16:52:57 +0000839- SF bug #1163563: the original fix for bug #1010677 ("thread Module
840 Breaks PyGILState_Ensure()") broke badly in the case of multiple
841 interpreter states; back out that fix and do a better job (see
842 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
843 for a longer write-up of the problem).
844
Michael W. Hudsondf888462005-06-03 14:41:55 +0000845- SF patch #1180995: marshal now uses a binary format by default when
846 serializing floats.
847
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000848- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
849 the routines that promise to produce IEEE 754 binary representations
850 of floats now simply copy bytes around.
851
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000852- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
853 278.
854
Brett Cannonc3647ac2005-04-26 03:45:26 +0000855- patch #1109424: int, long, float, complex, and unicode now check for the
856 proper magic slot for type conversions when subclassed. Previously the
857 magic slot was ignored during conversion. Semantics now match the way
858 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000859 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000860 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000861 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000862
Barry Warsawc8d907c2005-04-19 23:43:40 +0000863- Descriptors defined in C with a PyGetSetDef structure, where the setter is
864 NULL, now raise an AttributeError when attempting to set or delete the
865 attribute. Previously a TypeError was raised, but this was inconsistent
866 with the equivalent pure-Python implementation.
867
Michael W. Hudson774479c2005-04-18 08:46:17 +0000868- It is now safe to call PyGILState_Release() before
869 PyEval_InitThreads() (note that if there is reason to believe there
870 are multiple threads around you still must call PyEval_InitThreads()
871 before using the Python API; this fix is for extension modules that
872 have no way of knowing if Python is multi-threaded yet).
873
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000874- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
875 disabled caused a crash.
876
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000877- Bug #1165306: instancemethod_new allowed the creation of a method
878 with im_class == im_self == NULL, which caused a crash when called.
879
Tim Petersecc6e6a2005-07-10 22:30:55 +0000880- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000881 fixes the crash seen in bug #1165761
882
Raymond Hettinger96229b12005-03-11 06:49:40 +0000883- Added two new builtins, any() and all().
884
Brett Cannon409d8f22005-03-05 06:47:57 +0000885- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000886 (e.g., ``class C(): pass`` is no longer a syntax error).
887 Patch #1176012 added support to the 'parser' module and 'compiler' package
888 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000889
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000890- Patch #1115086: Support PY_LONGLONG in structmember.
891
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000892- Bug #1155938: new style classes did not check that __init__() was
893 returning None.
894
Tim Petersecc6e6a2005-07-10 22:30:55 +0000895- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000896 ('\') with a specific error message.
897
Martin v. Löwisff232d72005-03-03 09:24:38 +0000898- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
899
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000900- Bug #1124295: the __name__ attribute of file objects was
901 inadvertently made inaccessible in restricted mode.
902
Tim Petersecc6e6a2005-07-10 22:30:55 +0000903- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000904 an ferror() call.
905
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000906- min() and max() now support key= arguments with the same meaning as in
907 list.sort().

Jeremy Hyltonab630502005-02-04 18:44:06 +0000917- The parser did not complain about future statements in illegal
918 positions. It once again reports a syntax error if a future
919 statement occurs after anything other than a doc string.
920
Neil Schemenauercf52c072005-08-12 17:34:58 +0000921- Change the %s format specifier for str objects so that it returns a
922 unicode instance if the argument is not an instance of basestring and
923 calling __str__ on the argument returns a unicode instance.
924
Tim Petersf4e69282006-02-27 17:15:31 +0000925- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
926 current thread state when the auto-GIL-state machinery knows about
927 it (since the thread state is being deleted, continuing to remember it
928 can't help, but can hurt if another thread happens to get created with
929 the same thread id).

1119-------
1120
Nick Coghlan43832302006-04-23 17:04:07 +00001121- PEP 338: new module runpy defines a run_module function to support
1122 executing modules which provide access to source code or a code object
1123 via the PEP 302 import mechanisms.
1124
Anthony Baxter93f5b932006-04-03 08:05:07 +00001125- The email module's parsedate_tz function now sets the daylight savings

1133 in attribute values.
1134
Anthony Baxterc51ee692006-04-01 00:57:31 +00001135- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001136 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001137 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001138 module will not be built.
1139
Tim Petersc17976e2006-04-01 00:26:53 +00001140- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1141 aren't officially supported here, and trying to use them will probably
1142 raise an exception some day. But dicts have been allowed, and "mostly
1143 worked", so support for them won't go away without warning.
1144
Georg Brandl338ef7d2006-03-31 18:42:16 +00001145- Bug #1445068: getpass.getpass() can now be given an explicit stream
1146 argument to specify where to write the prompt.
1147
Georg Brandl22ec80b2006-03-31 18:25:44 +00001148- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1163
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001164- email 4.0 package now integrated. This is largely the same as the email 3.0
1165 package that was included in Python 2.3, except that PEP 8 module names are
1166 now used (e.g. mail.message instead of email.Message). The MIME classes
1167 have been moved to a subpackage (e.g. email.mime.text instead of
1168 email.MIMEText). The old names are still supported for now. Several
1169 deprecated Message methods have been removed and lots of bugs have been
1170 fixed. More details can be found in the email package documentation.
1171
Walter Dörwald40108c92006-03-27 08:15:44 +00001172- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1173 (a subclass of tuple) that provides incremental decoders and encoders
1174 (a way to use stateful codecs without the stream API). Python functions
1175 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1176 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()

1260
1261 "The consensus of researchers in this area (at least as
1262 expressed at the NIST Hash Function Workshop 10/31/05),
1263 is that SHA-256 is a good choice for the time being, but
1264 that research should continue, and other alternatives may
1265 arise from this research. The larger SHA's also seem OK."

Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001437 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1438
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001439- Bug #1110478: Revert os.environ.update to do putenv again.
1440
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001441- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1442
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001443- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1444
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001445- Enhancements to the csv module:
1446
1447 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001448 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001449 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001450 + Dialect parameter parsing has been re-implemented to improve error
1451 reporting.
1452 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1453 dictates.
1454 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001455 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001456 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001457 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1458 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001459 + reader now allows \r characters to be quoted (previously it only allowed
1460 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001461 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001462 + Dialect classes passed to the module are no longer instantiated by
1463 the module before being parsed (the former validation scheme required
1464 this, but the mechanism was unreliable).
1465 + The dialect registry now contains instances of the internal
1466 C-coded dialect type, rather than references to python objects.
1467 + the internal c-coded dialect type is now immutable.
1468 + register_dialect now accepts the same keyword dialect specifications
1469 as the reader and writer, allowing the user to register dialects
1470 without first creating a dialect class.
1471 + a configurable limit to the size of parsed fields has been added -
1472 previously, an unmatched quote character could result in the entire
1473 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001474 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001475 the parser field size limit (returning the former limit). The initial
1476 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001477 + A line_num attribute has been added to the reader object, which tracks
1478 the number of lines read from the source iterator. This is not
1479 the same as the number of records returned, as records can span
1480 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001481 + reader and writer objects were not being registered with the cyclic-GC.
1482 This has been fixed.
1483
Brett Cannone6539c42005-01-08 02:43:53 +00001484- _DummyThread objects in the threading module now delete self.__block that is
1485 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1486 lock primitives tend to be limited in number and thus should not be wasted on
1487 a _DummyThread object. Fixes bug #1089632.
1488
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001489- The imghdr module now detects Exif files.
1490
Raymond Hettinger6065d322004-12-20 23:51:53 +00001491- StringIO.truncate() now correctly adjusts the size attribute.
1492 (Bug #951915).
1493
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001494- locale.py now uses an updated locale alias table (built using
1495 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1496 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001497 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001498
Raymond Hettinger3557f422004-12-07 12:02:02 +00001499- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1500
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001501- the pickle module no longer accepts the deprecated None option in the
1502 args tuple returned by __reduce__().
1503
Brett Cannon84667c02004-12-07 03:25:18 +00001504- optparse now optionally imports gettext. This allows its use in setup.py.
1505
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001506- the pickle module no longer uses the deprecated bin parameter.
1507
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001508- the shelve module no longer uses the deprecated binary parameter.
1509
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001510- the pstats module no longer uses the deprecated ignore() method.
1511
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001512- the filecmp module no longer uses the deprecated use_statcache argument.
1513
Raymond Hettinger664347b2004-12-04 21:21:53 +00001514- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1515 extended or overridden by subclasses. Formerly, the subclassed method would
1516 be ignored by the rest of the module. (Bug #1078905).
1517
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001518- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001519 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001520
Walter Dörwald36733692004-12-22 12:50:50 +00001521- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1522 once when a size argument is given. This prevents a buffer overflow in the
1523 tokenizer with very long source lines.
1524
Barry Warsaw538561e2006-01-01 21:48:54 +00001525- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1526 immediately after creating the object, without any intervening
1527 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001528
Skip Montanaro05885812005-01-16 20:48:27 +00001529- The reconvert.quote function can now emit triple-quoted strings. The
1530 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001531
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001532- ``UserString.MutableString`` now supports negative indices in
1533 ``__setitem__`` and ``__delitem__``
1534
Greg Ward40407942005-03-05 02:53:17 +00001535- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1536 correctly.
1537
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001538- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1539 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1540 character even if the user has passed a size parameter to get a proper
1541 line ending. Remove the special handling of a "\r\n" that has been split
1542 between two lines.
1543
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001544- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1545 about illegal code points. The codec now supports PEP 293 style error
1546 handlers.
1547
Walter Dörwald78a78b02005-09-01 12:04:29 +00001548- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001549 from the input stream, so that the output is a byte string in the correct
1550 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001551
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001552- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1553 considering it exactly like a '*'.
1554
Walter Dörwald007f8df2005-10-09 19:42:27 +00001555- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1556 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001557
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001558- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1559
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001560- Patch #1413711: Certain patterns of differences were making difflib
1561 touch the recursion limit.
1562
Walter Dörwald58917a62006-03-31 15:26:22 +00001563- Bug #947906: An object oriented interface has been added to the calendar
1564 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001565 called as a script (e.g. via ``python -mcalendar``). Localized month and
1566 weekday names can be ouput (even if an exotic encoding is used) using
1567 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001568
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001569Build
1570-----
1571
Neal Norwitz602d3392006-03-31 08:21:40 +00001572- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1573 by using -mieee gcc option.
1574

1576
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001577- Build support for Win64-AMD64 was added.
1578
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001579- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1580
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001581- Patch #881820: look for openpty and forkpty also in libbsd.
1582
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001583- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1584 The zlib module is now builtin on Windows.
1585
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001586- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1587
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001588- Bug #1189330: configure did not correctly determine the necessary
1589 value of LINKCC if python was built with GCC 4.0.
1590
Trent Mick8321b422005-07-26 02:29:21 +00001591- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1592 vulnerability in zlib 1.2.1 and 1.2.2.
1593
Brett Cannon08cd5982005-04-24 22:26:38 +00001594- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1595 flags that change binary compatibility. Changes were also made to
1596 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001597 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001598
Bob Ippolitoed233462005-03-29 13:47:59 +00001599- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1600 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1601 no longer exists). This configure patch makes things right.
1602
Martin v. Löwise2713be2005-03-08 15:03:08 +00001603- Bug #1158607: Build with --disable-unicode again.
1604
Brett Cannon46d96232005-02-16 00:07:19 +00001605- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1606 defined. Discovered as a result of not being able to build on OS X.
1607
Brett Cannon516592f2004-12-07 00:42:59 +00001608- setup.py now uses the directories specified in LDFLAGS using the -L option
1609 and in CPPFLAGS using the -I option for adding library and include
1610 directories, respectively, for compiling extension modules against. This has
1611 led to the core being compiled using the values in CPPFLAGS. It also removes
1612 the need for the special-casing of both DarwinPorts and Fink for darwin since
1613 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1614 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1615 Fink, ``-I/opt/local/include`` for DarwinPorts).
1616
Brett Cannon43802422005-02-10 20:48:03 +00001617- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1618 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1619 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1620 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001622C API
1623-----
1624
Tim Petersc9d78aa2006-03-26 23:27:58 +00001625- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1626 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1627 is obtained via the ``PyObject_`` family, it must be released via the
1628 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1629 always been officially true, but when Python's small-object allocator was
1630 introduced, an attempt was made to cater to a few extension modules
1631 discovered at the time that obtained memory via ``PyObject_New`` but
1632 released it via ``PyMem_DEL``. It's years later, and if such code still
1633 exists it will fail now (probably with segfaults, but calling wrong
1634 low-level memory management functions can yield many symptoms).
1635
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001636- Added a C API for set and frozenset objects.
1637
Raymond Hettinger66517482004-12-03 11:45:13 +00001638- Removed PyRange_New().
1639
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001640- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1641 mapping argument now. This string is used as a mapping table. Byte values
1642 greater than the length of the string and 0xFFFE are treated as undefined
1643 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001650
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001651- Patch #1276356: New resource "urlfetch" is implemented. This enables
