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.

26-------
27
Thomas Heller5becdbe2006-07-06 08:48:35 +000028- Patch #1517790: It is now possible to use custom objects in the ctypes
29 foreign function argtypes sequence as long as they provide a from_param
30 method, no longer is it required that the object is a ctypes type.
31
Thomas Woutersadd19112006-07-05 11:03:49 +000032- string.Template() now correctly handles tuple-values. Previously,
33 multi-value tuples would raise an exception and single-value tuples would
34 be treated as the value they contain, instead.
35
Martin v. Löwisede77f52006-07-03 13:01:35 +000036- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
37 even if some data are received.
38
Martin v. Löwis45482392006-07-03 12:28:58 +000039- Bug #1267547: Put proper recursive setup.py call into the
40 spec file generated by bdist_rpm.
41

43 degrees and radians.
44
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000045- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +000046 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000047
Martin v. Löwisbd39c032006-07-03 09:44:00 +000048- Bug #1514703: Only setup canvas window in turtle when the canvas
49 is created.
50
Martin v. Löwis7596e832006-07-01 15:33:37 +000051- Bug #1513223: .close() of a _socketobj now releases the underlying
52 socket again, which then gets closed as it becomes unreferenced.
53
Thomas Hellerbde08132006-06-29 18:34:15 +000054- The '_ctypes' extension module now works when Python is configured
55 with the --without-threads option.
56
Fred Drake10497c82006-06-29 02:57:48 +000057- Bug #1504333: Make sgmllib support angle brackets in quoted
58 attribute values.
59
60- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
61 sgmllib ('[' and ']' were not accepted).
62
Georg Brandl1be63af2006-06-28 20:23:25 +000063- Fix a bug in the turtle module's end_fill function.
64
Brett Cannon53ab5b72006-06-22 16:49:14 +000065- Bug #1510580: The 'warnings' module improperly required that a Warning
66 category be either a types.ClassType and a subclass of Warning. The proper
67 check is just that it is a subclass with Warning as the documentation states.
68
Georg Brandlad29e632006-06-21 17:45:17 +000069- The compiler module now correctly compiles the new try-except-finally
70 statement (bug #1509132).
71
Neal Norwitz60373cd2006-06-22 06:30:50 +000072- The wsgiref package is now installed properly on Unix.
73
Vinay Sajip28e57612006-07-01 10:45:20 +000074- A bug was fixed in logging.config.fileConfig() which caused a crash on
75 shutdown when fileConfig() was called multiple times.
76
Gerhard Häring762fbd32006-07-02 17:48:30 +000077- The sqlite3 module did cut off data from the SQLite database at the first
78 null character before sending it to a custom converter. This has been fixed
79 now.

82-----------------
83
Martin v. Löwisee1e06d2006-07-02 18:44:00 +000084- Bug #1513646: os.access on Windows now correctly determines write
85 access, again.
86
Neal Norwitz0f8b31a2006-06-28 06:28:31 +000087- Bug #1512695: cPickle.loads could crash if it was interrupted with
88 a KeyboardInterrupt.
89
Neal Norwitza12aa882006-07-06 06:45:08 +000090- Bug #1296433: parsing XML with a non-default encoding and
91 a CharacterDataHandler could crash the interpreter in pyexpat.
92
Neal Norwitz3b6b8012006-06-27 04:12:58 +000093Build
94-----
95
Thomas Woutersfc34f6c2006-07-06 10:48:28 +000096- 'configure' now detects the zlib library the same way as distutils.
97 Previously, the slight difference could cause compilation errors of the
98 'zlib' module on systems with more than one version of zlib.
99
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000100- The MSI compileall step was fixed to also support a TARGETDIR
101 with spaces in it.
102
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000103- Bug #1517388: sqlite3.dll is now installed on Windows independent
104 of Tcl/Tk.
105
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000106- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000107 trying to be installed even though it's empty.

111
112- Call os.waitpid() at the end of tests that spawn child processes in order
113 to minimize resources (zombies).

126Core and builtins
127-----------------
128
Georg Brandla56b9152006-06-19 06:35:54 +0000129- Patch #1507676: Error messages returned by invalid abstract object operations
130 (such as iterating over an integer) have been improved and now include the
131 type of the offending object to help with debugging.
132
Brett Cannonea3912b2006-06-13 21:46:41 +0000133- Bug #992017: A classic class that defined a __coerce__() method that returned
134 its arguments swapped would infinitely recurse and segfault the interpreter.
135
Neal Norwitz909eb122006-06-12 02:13:21 +0000136- Fix the socket tests so they can be run concurrently.
137
Neal Norwitzb9845e72006-06-12 02:11:18 +0000138- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000139 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000140
Brett Cannon22565aa2006-06-09 22:31:23 +0000141- Bug #532646: object.__call__() will continue looking for the __call__
142 attribute on objects until one without one is found. This leads to recursion
143 when you take a class and set its __call__ attribute to an instance of the
144 class. Originally fixed for classic classes, but this fix is for new-style.
145 Removes the infinite_rec_3 crasher.
146
Georg Brandl24250812006-06-09 18:45:48 +0000147- The string and unicode methods startswith() and endswith() now accept
148 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
149
Brett Cannonde3b0522006-06-08 17:00:45 +0000150- Buffer objects, at the C level, never used the char buffer
151 implementation even when the char buffer for the wrapped object was
152 explicitly requested (originally returned the read or write buffer).
153 Now a TypeError is raised if the char buffer is not present but is
154 requested.
155
Georg Brandlddbaa662006-06-04 21:56:52 +0000156- Patch #1346214: Statements like "if 0: suite" are now again optimized
157 away like they were in Python 2.4.
158
Georg Brandlb7c8f542006-05-27 12:30:25 +0000159- Builtin exceptions are now full-blown new-style classes instead of
160 instances pretending to be classes, which speeds up exception handling
161 by about 80% in comparison to 2.5a2.
162
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000163- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
164 Unicode 4.1.
165
Georg Brandlf4ef1162006-05-26 18:03:31 +0000166- Patch #921466: sys.path_importer_cache is now used to cache valid and
167 invalid file paths for the built-in import machinery which leads to
168 fewer open calls on startup.
169
Tim Peters696cf432006-05-24 21:10:40 +0000170- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
171 of-2 bases. The largest speedup is for inputs with about 1000 decimal
172 digits. Conversion from non-power-of-2 bases remains quadratic-time in
173 the number of input digits (it was and remains linear-time for bases
174 2, 4, 8, 16 and 32).
175
Tim Petersb713ec22006-05-23 18:45:30 +0000176- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
177 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
178 an integer close to ``sys.maxint``. This was repaired by patch
179 #1335972, which also gives a nice speedup.
180
Richard Jonescebbefc2006-05-23 18:28:17 +0000181- Patch #1337051: reduced size of frame objects.
182
183- PyErr_NewException now accepts a tuple of base classes as its
184 "base" parameter.
185
Richard Jones7c88dcc2006-05-23 10:37:38 +0000186- Patch #876206: function call speedup by retaining allocated frame
187 objects.
188
Georg Brandl7b90e162006-05-18 07:01:27 +0000189- Bug #1462152: file() now checks more thoroughly for invalid mode
190 strings and removes a possible "U" before passing the mode to the
191 C library function.
192
Neal Norwitz1004a532006-05-15 07:17:23 +0000193- Patch #1488312, Fix memory alignment problem on SPARC in unicode
194
Neal Norwitz373f0a72006-05-15 07:04:36 +0000195- Bug #1487966: Fix SystemError with conditional expression in assignment
196
Martin v. Löwis879768d2006-05-11 13:28:43 +0000197- WindowsError now has two error code attributes: errno, which carries
198 the error values from errno.h, and winerror, which carries the error
199 values from winerror.h. Previous versions put the winerror.h values
200 (from GetLastError()) into the errno attribute.
201
Martin v. Löwis77736712006-05-04 05:51:03 +0000202- Patch #1475845: Raise IndentationError for unexpected indent.
203
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000204- Patch #1479181: split open() and file() from being aliases for each other.
205
Tim Peters44bd9862006-06-01 13:49:23 +0000206- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
207 methods were always silently ignored by dictionaries when comparing keys.
208 They are now passed through (except when using the C API function
209 ``PyDict_GetItem()``, whose semantics did not change).
210
211- Bug #1456209: In some obscure cases it was possible for a class with a
212 custom ``__eq__()`` method to confuse dict internals when class instances
213 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
214 No, you don't have any code that did this ;-)

220
221- Patch #1462338: Upgrade pyexpat to expat 2.0.0
222
Brett Cannon6ee7d012006-06-08 16:23:04 +0000223- Change binascii.hexlify to accept a read-only buffer instead of only a char
224 buffer and actually follow its documentation.
225
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000226- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
227
Nick Coghlanc649ec52006-05-29 12:43:05 +0000228- Patch #1478788 (modified version): The functional extension module has
229 been renamed to _functools and a functools Python wrapper module added.
230 This provides a home for additional function related utilities that are
231 not specifically about functional programming. See PEP 309.
232
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000233- Patch #1493701: performance enhancements for struct module.
234

241 enabled builds on Windows and systems with Posix threads support.
242
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000243- On Win32, os.listdir now supports arbitrarily-long Unicode path names
244 (up to the system limit of 32K characters).
245
246- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
247 As a result, these functions now raise WindowsError instead of OSError.
248
Tim Peters7a822da2006-05-25 21:50:17 +0000249- ``time.clock()`` on Win64 should use the high-performance Windows
250 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
251 Windows platforms).
252
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000253- Calling Tk_Init twice is refused if the first call failed as that
254 may deadlock.
255
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000256- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
257 accept it without potentially using an uninitialized pointer.
258
259- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
260 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
261 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000262

265
Gregory P. Smith372b5832006-06-05 18:48:21 +0000266- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
267 parameter is supplied. [SF pybsddb bug #1477863]
268
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000269- bsddb: the __len__ method of a DB object has been fixed to return correct
270 results. It could previously incorrectly return 0 in some cases.
271 Fixes SF bug 1493322 (pybsddb bug 1184012).
272
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000273- bsddb: the bsddb.dbtables Modify method now raises the proper error and
274 aborts the db transaction safely when a modifier callback fails.
275 Fixes SF python patch/bug #1408584.
276
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000277- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000278 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000279 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
280 database calls that would previously deadlock. [SF python bug #775414]
281

Tim Peters43898b42006-06-14 04:09:25 +0000312- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
313 guarantee that adjacent triples in the return list always describe
314 non-adjacent blocks. Previously, a pair of matching blocks could end
315 up being described by multiple adjacent triples that formed a partition
316 of the matching pair.
317
Greg Ward0e0c9f42006-06-11 16:24:11 +0000318- Bug #1498146: fix optparse to handle Unicode strings in option help,
319 description, and epilog.
320
Greg Wardd1c797e2006-06-11 14:42:41 +0000321- Bug #1366250: minor optparse documentation error.
322
Greg Ward7f547402006-06-11 00:40:49 +0000323- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
324 clarify docs.
325
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000326- The wsgiref package has been added to the standard library.
327
Nick Coghlan676725d2006-06-08 13:54:49 +0000328- The functions update_wrapper() and wraps() have been added to the functools
329 module. These make it easier to copy relevant metadata from the original
330 function when writing wrapper functions.
331
Tim Petersd6a9eef2006-06-05 01:48:21 +0000332- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
333 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000334
Martin v. Löwis3f767792006-06-04 19:36:28 +0000335- Patch #1359618: Speed up charmap encoder by using a trie structure
336 for lookup.
337
Tim Petersd609b1a2006-06-02 23:22:51 +0000338- The functions in the ``pprint`` module now sort dictionaries by key
339 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
340 if and only if its display required more than one line, although that
341 wasn't documented. The new behavior increases predictability; e.g.,
342 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
343
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000344- Patch #1497027: try HTTP digest auth before basic auth in urllib2
345 (thanks for J. J. Lee).
346
Georg Brandl2b330372006-05-28 20:23:12 +0000347- Patch #1496206: improve urllib2 handling of passwords with respect to
348 default HTTP and HTTPS ports.
349
George Yoshidaf3c65de2006-05-28 16:39:09 +0000350- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
351
Bob Ippolito7298f272006-05-23 18:43:47 +0000352- Patch #1281707: speed up gzip.readline.
353
Georg Brandlb89316f2006-05-17 15:51:16 +0000354- Patch #1180296: Two new functions were added to the locale module:
355 format_string() to get the effect of "format % items" but locale-aware,
356 and currency() to format a monetary number with currency sign.
357
Georg Brandle3a25832006-05-17 14:56:04 +0000358- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
359 and several features added, such as speed and geometry control.
360
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000361- Patch #1488881: add support for external file objects in bz2 compressed
362 tarfiles.
363
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000364- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
365 stdout arguments, making it possible to redirect input and output
366 for remote debugging.
367
368- Patch #1484695: Update the tarfile module to version 0.8. This fixes
369 a couple of issues, notably handling of long file names using the
370 GNU LONGNAME extension.
371
372- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
373 new flag when ``name`` is already the name of an option flag.
374
375- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
376 package.
377
378- Patch #1472854: make the rlcompleter.Completer class usable on non-
379 UNIX platforms.
380
381- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
382
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000383- Bug #1472827: correctly escape newlines and tabs in attribute values in
384 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000414What's New in Python 2.5 alpha 2?
415=================================
416
417*Release date: 27-APR-2006*
418
419Core and builtins
420-----------------
421
Thomas Heller1b046642006-04-18 18:51:06 +0000422- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
423 by converting these apis from macros into exported functions again:
424
425 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
426 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
427 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
428 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
429 PyRun_String Py_CompileString
430
Martin v. Löwis45294a92006-04-18 06:24:08 +0000431- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
432
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000433- All uses of PyStructSequence_InitType have been changed to initialize
434 the type objects only once, even if the interpreter is initialized
435 multiple times.
436
Neal Norwitz61546162006-04-14 05:20:28 +0000437- Bug #1454485, array.array('u') could crash the interpreter. This was
438 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
439 to unicode when it didn't make sense. 'u#' now requires a unicode string.
440
441- Py_UNICODE is unsigned. It was always documented as unsigned, but
442 due to a bug had a signed value in previous versions.
443
Tim Peters3a5e8b12006-04-11 01:44:07 +0000444- Patch #837242: ``id()`` of any Python object always gives a positive
445 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
446 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000447 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000448 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000449
Tim Peters3a5e8b12006-04-11 01:44:07 +0000450 def __hash__(self):
451 return id(self) # WRONG
452
453 because a hash result must be a (short) Python int but it was always
454 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000455 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000456 was always usable as a hash value before this patch. That's no longer
457 necessarily so.
458
459- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000460 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000461 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000462 #1454844)
463
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000464- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
465 involving generators that have paused outside of any ``try`` or ``with``
466 blocks. (In 2.5a1, a paused generator that was part of a reference
467 cycle could not be garbage collected, regardless of whether it was
468 paused in a ``try`` or ``with`` block.)

477 fails with an error condition.
478
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000479- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
480
481- Bug #1117761: bsddb.*open() no longer raises an exception when using
482 the cachesize parameter.
483
484- Bug #1149413: bsddb.*open() no longer raises an exception when using
485 a temporary db (file=None) with the 'n' flag to truncate on open.
486
487- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
488 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000489
Armin Rigoa9017c32006-04-19 11:50:27 +0000490- Patch #1062014: AF_UNIX sockets under Linux have a special
491 abstract namespace that is now fully supported.
492
Anthony Baxter51bcb682006-04-05 14:51:42 +0000493Library
494-------
495
Tim Peters711bf302006-04-25 03:31:36 +0000496- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
497 a doctest to be skipped (the code is not run, and the expected output
498 or exception is ignored).
499
Nick Coghlanda2268f2006-04-24 04:37:15 +0000500- Fixed contextlib.nested to cope with exceptions being raised and
501 caught inside exit handlers.
502
Greg Wardab05edc2006-04-23 03:47:58 +0000503- Updated optparse module to Optik 1.5.1 (allow numeric constants in
504 hex, octal, or binary; add ``append_const`` action; keep going if
505 gettext cannot be imported; added ``OptionParser.destroy()`` method;
506 added ``epilog`` for better help generation).
507
Tim Peters21fbd572006-04-21 21:18:10 +0000508- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
509 called from a thread spawned as a side effect of importing a module.
510
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000511- The pydoc module now supports documenting packages contained in
512 .zip or .egg files.
513
514- The pkgutil module now has several new utility functions, such
515 as ``walk_packages()`` to support working with packages that are either
516 in the filesystem or zip files.
517
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000518- The mailbox module can now modify and delete messages from
519 mailboxes, in addition to simply reading them. Thanks to Gregory
520 K. Johnson for writing the code, and to the 2005 Google Summer of
521 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000522
Tim Petersc7605f22006-04-17 21:12:33 +0000523- The ``__del__`` method of class ``local`` in module ``_threading_local``
524 returned before accomplishing any of its intended cleanup.
525
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000526- Patch #790710: Add breakpoint command lists in pdb.
527
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000528- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000530- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
531
Anthony Baxtere29002c2006-04-12 12:07:31 +0000532- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
533 Windows. Bug #1469163.
534
Phillip J. Eby47032112006-04-11 01:07:43 +0000535- The warnings, linecache, inspect, traceback, site, and doctest modules
536 were updated to work correctly with modules imported from zipfiles or
537 via other PEP 302 __loader__ objects.
538
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000539- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis4be4e652006-04-17 19:25:49 +0000552- The Makefile now has a reindent target, which runs reindent.py on
553 the library.
554

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000559- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
560 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000561 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000562 CXX from --with-cxx-main, see description in README.
563
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000564- Patch #1429775: Link extension modules with the shared libpython.

567
Tim Peters8931ff12006-05-13 23:28:20 +0000568- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
569 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
570 and "%zu" for unsigned integers of type ``size_t``.

574
Nick Coghlanda2268f2006-04-24 04:37:15 +0000575- test_contextlib now checks contextlib.nested can cope with exceptions
576 being raised and caught inside exit handlers.
577
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000578- test_cmd_line now checks operation of the -m and -c command switches
579
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000580- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
581 it separately and by hand. It also wasn't cleaning up its changes to
582 the current Decimal context.
583
Thomas Woutersabd08882006-04-26 15:53:30 +0000584- regrtest.py now has a -M option to run tests that test the new limits of
585 containers, on 64-bit architectures. Running these tests is only sensible
586 on 64-bit machines with more than two gigabytes of memory. The argument
587 passed is the maximum amount of memory for the tests to use.

596-------------
597
Tim Petersb06d28c2006-05-12 01:57:59 +0000598- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
599
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000600- PEP 343: Added Context Types section to the library reference
601 and attempted to bring other PEP 343 related documentation into
602 line with the implementation and/or python-dev discussions.
603
Tim Peters8dc73d22006-04-24 02:03:16 +0000604- Bug #1337990: clarified that ``doctest`` does not support examples

615
Nick Coghlan43832302006-04-23 17:04:07 +0000616- PEP 338: -m command line switch now delegates to runpy.run_module
617 allowing it to support modules in packages and zipfiles
618
Martin v. Löwisc661b882006-04-20 04:54:23 +0000619- On Windows, .DLL is not an accepted file name extension for
620 extension modules anymore; extensions are only found if they
621 end in .PYD.
622
Martin v. Löwisea62d252006-04-03 10:56:49 +0000623- Bug #1421664: sys.stderr.encoding is now set to the same value as
624 sys.stdout.encoding.
625
Neal Norwitz92e212f2006-04-03 04:48:37 +0000626- __import__ accepts keyword arguments.

633 5.4 and later versions.
634
Neal Norwitze98ccf62006-03-23 05:39:47 +0000635- Bug #1115379: Compiling a Unicode string with an encoding declaration
636 now gives a SyntaxError.
637
Georg Brandlabd1ff82006-03-18 07:59:59 +0000638- Previously, Python code had no easy way to access the contents of a
639 cell object. Now, a ``cell_contents`` attribute has been added
640 (closes patch #1170323).
641
Tim Peterscf79aac2006-03-16 01:14:46 +0000642- Patch #1123430: Python's small-object allocator now returns an arena to
643 the system ``free()`` when all memory within an arena becomes unused
644 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
645 freed. Some applications will see a drop in virtual memory size now,
646 especially long-running applications that, from time to time, temporarily
647 use a large number of small objects. Note that when Python returns an
648 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000649 platform C library will in turn return that memory to the operating system.
650 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000651 appears to be effective at least on Microsoft C and gcc-based systems.
652 Thanks to Evan Jones for hard work and patience.
653
Georg Brandl533ff6f2006-03-08 18:09:27 +0000654- Patch #1434038: property() now uses the getter's docstring if there is
655 no "doc" argument given. This makes it possible to legitimately use
656 property() as a decorator to produce a read-only property.
657
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000658- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
659 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
660 of requiring an int or long in slicing and a few other contexts, enabling
661 other objects (e.g. Numeric Python's integers) to be used as slice indices.
662
Neal Norwitz995acdf2006-03-07 05:01:00 +0000663- Fixed various bugs reported by Coverity's Prevent tool.
664
Brett Cannonbf364092006-03-01 04:25:17 +0000665- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
666 new exception base class, BaseException, which has a new message attribute.
667 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
668 Raising a string exception now raises a DeprecationWarning.
669
Thomas Woutersfb609f42006-02-28 16:37:25 +0000670- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
671 explicitly relative, using 'from .module import name' to mean 'from the same
672 package as this module is in. Imports without dots still default to the
673 old relative-then-absolute, unless 'from __future__ import
674 absolute_import' is used.
675
Brett Cannona7446e32006-02-27 23:39:10 +0000676- Properly check if 'warnings' raises an exception (usually when a filter set
677 to "error" is triggered) when raising a warning for raising string
678 exceptions.
679
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000680- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000681 The name was removed from Include/code.h.
682
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000683- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000684
Guido van Rossum1968ad32006-02-25 22:38:04 +0000685- Patch 1433928:
686 - The copy module now "copies" function objects (as atomic objects).
687 - dict.__getitem__ now looks for a __missing__ hook before raising
688 KeyError.
689
Tim Peters84ef21c2006-02-28 20:39:06 +0000690- PEP 343: with statement implemented. Needs ``from __future__ import
691 with_statement``. Use of 'with' as a variable will generate a warning.
692 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000693 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000694 The following objects have __context__ methods:
695 - The built-in file type.
696 - The thread.LockType type.
697 - The following types defined by the threading module:
698 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
699 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000700
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000701- Fix the encodings package codec search function to only search
702 inside its own package. Fixes problem reported in patch #1433198.
703
704 Note: Codec packages should implement and register their own
705 codec search function. PEP 100 has the details.
706
Tim Peters9ea89d22006-06-04 03:26:02 +0000707- PEP 353: Using ``Py_ssize_t`` as the index type.
708
709- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
710 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
711 now allow Python to make use of memory blocks exceeding 2**32 bytes for
712 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
713 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000714
Neal Norwitzfc76d632006-01-10 06:03:13 +0000715- Patch #1400181, fix unicode string formatting to not use the locale.
716 This is how string objects work. u'%f' could use , instead of .
717 for the decimal point. Now both strings and unicode always use periods.
718
Neal Norwitz671b9e32006-01-09 07:07:12 +0000719- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
720 configure would break checking curses.h.
721
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000722- Bug #959576: The pwd module is now builtin. This allows Python to be
723 built on UNIX platforms without $HOME set.
724
Neal Norwitzc10978f2005-12-19 06:07:16 +0000725- Bug #1072182, fix some potential problems if characters are signed.
726
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000727- Bug #889500, fix line number on SyntaxWarning for global declarations.
728
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000729- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
730
Neal Norwitze7214a12005-12-18 05:03:17 +0000731- Support for converting hex strings to floats no longer works.
732 This was not portable. float('0x3') now raises a ValueError.
733
Barry Warsaw2a38a862005-12-18 01:27:35 +0000734- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000735 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000736 is now displayed in interactive prompt banner.
737
Georg Brandlfa166682005-12-17 21:45:17 +0000738- Implementation of PEP 341 - Unification of try/except and try/finally.
739 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000740 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000741
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000742- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
743 now encodes backslash correctly.
744
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000745- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
746
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000747- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000748 and long longs.
749
Neal Norwitz67715f02005-11-09 06:59:35 +0000750- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000751 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000752 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000753
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000754- Replaced most Unicode charmap codecs with new ones using the
755 new Unicode translate string feature in the builtin charmap
756 codec; the codecs were created from the mapping tables available
757 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
758 encodings now include a mapping for the Apple logo)
759
Tim Peterse3547fd2005-12-16 23:13:57 +0000760- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000761
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000762- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000763
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000764- A new AST parser implementation was completed. The abstract
765 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000766 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000767
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000768- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000769 The following code now raises a SyntaxError: foo(a = i for i in range(10))
770
Neal Norwitz708e51a2005-10-03 04:48:15 +0000771- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
772
Neal Norwitz11bd1192005-10-03 00:54:56 +0000773- SF Bug #887946: fix segfault when redirecting stdin from a directory.
774 Provide a warning when a directory is passed on the command line.
775
Neal Norwitz40d37812005-10-02 01:48:49 +0000776- Fix segfault with invalid coding.
777
778- SF bug #772896: unknown encoding results in MemoryError.
779
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000780- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000781 supported a __len__() method which evaluated to False when the iterator
782 was empty.
783
Guido van Rossum630db602005-09-20 18:49:54 +0000784- On 64-bit platforms, when __len__() returns a value that cannot be
785 represented as a C int, raise OverflowError.
786
Skip Montanarof8948ca2005-09-19 03:54:46 +0000787- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000788 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000789
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000790- SF bug #893549: parsing keyword arguments was broken with a few format
791 codes.
792
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000793- Changes donated by Elemental Security to make it work on AIX 5.3
794 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
795 bug #105470: test_pwd fails on 64bit system (Opteron).
796
Guido van Rossum539c6622005-09-14 17:49:54 +0000797- Changes donated by Elemental Security to make it work on HP-UX 11 on
798 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
799
Georg Brandl4550b8d2005-08-26 06:43:52 +0000800- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000801 (fixes bug #1119418).
802
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000803- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
804
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000805- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
806 exceptions that cause a function to exit.
807
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000808- The implementation of set() and frozenset() was revised to use its
809 own internal data structure. Memory consumption is reduced by 1/3
810 and there are modest speed-ups as well. The API is unchanged.
811
Tim Petersde7990b2005-07-17 23:45:23 +0000812- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
813
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000814- SF bug #1229429: PyObject_CallMethod failed to decrement some
815 reference counts in some error exit cases.
816
Tim Petersecc6e6a2005-07-10 22:30:55 +0000817- SF bug #1185883: Python's small-object memory allocator took over
818 a block managed by the platform C library whenever a realloc specified
819 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000820 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000821 portable way to copy data from the C-managed block into Python's
822 small-object space without risking a memory fault. Python's small-object
823 realloc now leaves such blocks under the control of the platform C
824 realloc.
825
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000826- SF bug #1232517: An overflow error was not detected properly when
827 attempting to convert a large float to an int in os.utime().
828
Raymond Hettinger3296e692005-06-29 23:29:56 +0000829- SF bug #1224347: hex longs now print with lowercase letters just
830 like their int counterparts.
831
Michael W. Hudson188d4362005-06-20 16:52:57 +0000832- SF bug #1163563: the original fix for bug #1010677 ("thread Module
833 Breaks PyGILState_Ensure()") broke badly in the case of multiple
834 interpreter states; back out that fix and do a better job (see
835 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
836 for a longer write-up of the problem).
837
Michael W. Hudsondf888462005-06-03 14:41:55 +0000838- SF patch #1180995: marshal now uses a binary format by default when
839 serializing floats.
840
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000841- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
842 the routines that promise to produce IEEE 754 binary representations
843 of floats now simply copy bytes around.
844
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000845- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
846 278.
847
Brett Cannonc3647ac2005-04-26 03:45:26 +0000848- patch #1109424: int, long, float, complex, and unicode now check for the
849 proper magic slot for type conversions when subclassed. Previously the
850 magic slot was ignored during conversion. Semantics now match the way
851 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000852 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000853 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000854 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000855
Barry Warsawc8d907c2005-04-19 23:43:40 +0000856- Descriptors defined in C with a PyGetSetDef structure, where the setter is
857 NULL, now raise an AttributeError when attempting to set or delete the
858 attribute. Previously a TypeError was raised, but this was inconsistent
859 with the equivalent pure-Python implementation.
860
Michael W. Hudson774479c2005-04-18 08:46:17 +0000861- It is now safe to call PyGILState_Release() before
862 PyEval_InitThreads() (note that if there is reason to believe there
863 are multiple threads around you still must call PyEval_InitThreads()
864 before using the Python API; this fix is for extension modules that
865 have no way of knowing if Python is multi-threaded yet).
866
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000867- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
868 disabled caused a crash.
869
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000870- Bug #1165306: instancemethod_new allowed the creation of a method
871 with im_class == im_self == NULL, which caused a crash when called.
872
Tim Petersecc6e6a2005-07-10 22:30:55 +0000873- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000874 fixes the crash seen in bug #1165761
875
Raymond Hettinger96229b12005-03-11 06:49:40 +0000876- Added two new builtins, any() and all().
877
Brett Cannon409d8f22005-03-05 06:47:57 +0000878- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000879 (e.g., ``class C(): pass`` is no longer a syntax error).
880 Patch #1176012 added support to the 'parser' module and 'compiler' package
881 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000882
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000883- Patch #1115086: Support PY_LONGLONG in structmember.
884
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000885- Bug #1155938: new style classes did not check that __init__() was
886 returning None.
887
Tim Petersecc6e6a2005-07-10 22:30:55 +0000888- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000889 ('\') with a specific error message.
890
Martin v. Löwisff232d72005-03-03 09:24:38 +0000891- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
892
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000893- Bug #1124295: the __name__ attribute of file objects was
894 inadvertently made inaccessible in restricted mode.
895
Tim Petersecc6e6a2005-07-10 22:30:55 +0000896- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000897 an ferror() call.
898
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000899- min() and max() now support key= arguments with the same meaning as in
900 list.sort().
901
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000902- The peephole optimizer now performs simple constant folding in expressions:
903 (2+3) --> (5).
904
Raymond Hettingera422c342005-01-11 03:03:27 +0000905- set and frozenset objects can now be marshalled. SF #1098985.
906
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000907- Bug #1077106: Poor argument checking could cause memory corruption
908 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000909
Jeremy Hyltonab630502005-02-04 18:44:06 +0000910- The parser did not complain about future statements in illegal
911 positions. It once again reports a syntax error if a future
912 statement occurs after anything other than a doc string.
913
Neil Schemenauercf52c072005-08-12 17:34:58 +0000914- Change the %s format specifier for str objects so that it returns a
915 unicode instance if the argument is not an instance of basestring and
916 calling __str__ on the argument returns a unicode instance.
917
Tim Petersf4e69282006-02-27 17:15:31 +0000918- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
919 current thread state when the auto-GIL-state machinery knows about
920 it (since the thread state is being deleted, continuing to remember it
921 can't help, but can hurt if another thread happens to get created with
922 the same thread id).

1103 islice(s.start, s.stop, s.step)
1104
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001105- datetime.datetime() now has a strptime class method which can be used to

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001111Library
1112-------
1113
Nick Coghlan43832302006-04-23 17:04:07 +00001114- PEP 338: new module runpy defines a run_module function to support
1115 executing modules which provide access to source code or a code object
1116 via the PEP 302 import mechanisms.
1117
Anthony Baxter93f5b932006-04-03 08:05:07 +00001118- The email module's parsedate_tz function now sets the daylight savings
1119 flag to -1 (unknown) since it can't tell from the date whether it should
1120 be set.
1121
Fred Drakead5177c2006-04-01 22:14:43 +00001122- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
1123 now sport attributes that provide access to the parts of the result.

1126 in attribute values.
1127
Anthony Baxterc51ee692006-04-01 00:57:31 +00001128- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001129 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001130 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001131 module will not be built.
1132
Tim Petersc17976e2006-04-01 00:26:53 +00001133- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1134 aren't officially supported here, and trying to use them will probably
1135 raise an exception some day. But dicts have been allowed, and "mostly
1136 worked", so support for them won't go away without warning.
1137
Georg Brandl338ef7d2006-03-31 18:42:16 +00001138- Bug #1445068: getpass.getpass() can now be given an explicit stream
1139 argument to specify where to write the prompt.
1140
Georg Brandl22ec80b2006-03-31 18:25:44 +00001141- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1156
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001157- email 4.0 package now integrated. This is largely the same as the email 3.0
1158 package that was included in Python 2.3, except that PEP 8 module names are
1159 now used (e.g. mail.message instead of email.Message). The MIME classes
1160 have been moved to a subpackage (e.g. email.mime.text instead of
1161 email.MIMEText). The old names are still supported for now. Several
1162 deprecated Message methods have been removed and lots of bugs have been
1163 fixed. More details can be found in the email package documentation.
1164
Walter Dörwald40108c92006-03-27 08:15:44 +00001165- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1166 (a subclass of tuple) that provides incremental decoders and encoders
1167 (a way to use stateful codecs without the stream API). Python functions
1168 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1169 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1170 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001171
Walter Dörwald067db482006-03-15 22:17:27 +00001172- Patch #1359365: Calling next() on a closed StringIO.String object raises
1173 a ValueError instead of a StopIteration now (like file and cString.String do).
1174 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been

1253
1254 "The consensus of researchers in this area (at least as
1255 expressed at the NIST Hash Function Workshop 10/31/05),
1256 is that SHA-256 is a good choice for the time being, but
1257 that research should continue, and other alternatives may
1258 arise from this research. The larger SHA's also seem OK."

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001434- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1435
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001436- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1437
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001438- Enhancements to the csv module:
1439
1440 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001441 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001442 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001443 + Dialect parameter parsing has been re-implemented to improve error
1444 reporting.
1445 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1446 dictates.
1447 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001448 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001449 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001450 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1451 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001452 + reader now allows \r characters to be quoted (previously it only allowed
1453 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001454 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001455 + Dialect classes passed to the module are no longer instantiated by
1456 the module before being parsed (the former validation scheme required
1457 this, but the mechanism was unreliable).
1458 + The dialect registry now contains instances of the internal
1459 C-coded dialect type, rather than references to python objects.
1460 + the internal c-coded dialect type is now immutable.
1461 + register_dialect now accepts the same keyword dialect specifications
1462 as the reader and writer, allowing the user to register dialects
1463 without first creating a dialect class.
1464 + a configurable limit to the size of parsed fields has been added -
1465 previously, an unmatched quote character could result in the entire
1466 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001467 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001468 the parser field size limit (returning the former limit). The initial
1469 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001470 + A line_num attribute has been added to the reader object, which tracks
1471 the number of lines read from the source iterator. This is not
1472 the same as the number of records returned, as records can span
1473 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001474 + reader and writer objects were not being registered with the cyclic-GC.
1475 This has been fixed.
1476
Brett Cannone6539c42005-01-08 02:43:53 +00001477- _DummyThread objects in the threading module now delete self.__block that is
1478 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1479 lock primitives tend to be limited in number and thus should not be wasted on
1480 a _DummyThread object. Fixes bug #1089632.
1481
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001482- The imghdr module now detects Exif files.
1483
Raymond Hettinger6065d322004-12-20 23:51:53 +00001484- StringIO.truncate() now correctly adjusts the size attribute.
1485 (Bug #951915).
1486
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001487- locale.py now uses an updated locale alias table (built using
1488 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1489 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001490 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001491
Raymond Hettinger3557f422004-12-07 12:02:02 +00001492- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1493
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001494- the pickle module no longer accepts the deprecated None option in the
1495 args tuple returned by __reduce__().
1496
Brett Cannon84667c02004-12-07 03:25:18 +00001497- optparse now optionally imports gettext. This allows its use in setup.py.
1498
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001499- the pickle module no longer uses the deprecated bin parameter.
1500
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001501- the shelve module no longer uses the deprecated binary parameter.
1502
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001503- the pstats module no longer uses the deprecated ignore() method.
1504
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001505- the filecmp module no longer uses the deprecated use_statcache argument.
1506
Raymond Hettinger664347b2004-12-04 21:21:53 +00001507- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1508 extended or overridden by subclasses. Formerly, the subclassed method would
1509 be ignored by the rest of the module. (Bug #1078905).
1510
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001511- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001512 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001513
Walter Dörwald36733692004-12-22 12:50:50 +00001514- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1515 once when a size argument is given. This prevents a buffer overflow in the
1516 tokenizer with very long source lines.
1517
Barry Warsaw538561e2006-01-01 21:48:54 +00001518- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1519 immediately after creating the object, without any intervening
1520 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001521
Skip Montanaro05885812005-01-16 20:48:27 +00001522- The reconvert.quote function can now emit triple-quoted strings. The
1523 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001524
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001525- ``UserString.MutableString`` now supports negative indices in
1526 ``__setitem__`` and ``__delitem__``
1527
Greg Ward40407942005-03-05 02:53:17 +00001528- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1529 correctly.
1530
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001531- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1532 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1533 character even if the user has passed a size parameter to get a proper
1534 line ending. Remove the special handling of a "\r\n" that has been split
1535 between two lines.
1536
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001537- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1538 about illegal code points. The codec now supports PEP 293 style error
1539 handlers.
1540
Walter Dörwald78a78b02005-09-01 12:04:29 +00001541- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001542 from the input stream, so that the output is a byte string in the correct
1543 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001544
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001545- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1546 considering it exactly like a '*'.
1547
Walter Dörwald007f8df2005-10-09 19:42:27 +00001548- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1549 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001550
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001551- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1552
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001553- Patch #1413711: Certain patterns of differences were making difflib
1554 touch the recursion limit.
1555
Walter Dörwald58917a62006-03-31 15:26:22 +00001556- Bug #947906: An object oriented interface has been added to the calendar
1557 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001558 called as a script (e.g. via ``python -mcalendar``). Localized month and
1559 weekday names can be ouput (even if an exotic encoding is used) using
1560 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001561
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001562Build

1564
Neal Norwitz602d3392006-03-31 08:21:40 +00001565- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1566 by using -mieee gcc option.
1567

1569
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001570- Build support for Win64-AMD64 was added.
1571
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001572- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1573
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001574- Patch #881820: look for openpty and forkpty also in libbsd.
1575
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001576- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1577 The zlib module is now builtin on Windows.
1578
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001579- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1580
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001581- Bug #1189330: configure did not correctly determine the necessary
1582 value of LINKCC if python was built with GCC 4.0.
1583
Trent Mick8321b422005-07-26 02:29:21 +00001584- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1585 vulnerability in zlib 1.2.1 and 1.2.2.
1586
Brett Cannon08cd5982005-04-24 22:26:38 +00001587- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1588 flags that change binary compatibility. Changes were also made to
1589 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001590 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001591
Bob Ippolitoed233462005-03-29 13:47:59 +00001592- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1593 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1594 no longer exists). This configure patch makes things right.
1595
Martin v. Löwise2713be2005-03-08 15:03:08 +00001596- Bug #1158607: Build with --disable-unicode again.
1597
Brett Cannon46d96232005-02-16 00:07:19 +00001598- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1599 defined. Discovered as a result of not being able to build on OS X.
1600
Brett Cannon516592f2004-12-07 00:42:59 +00001601- setup.py now uses the directories specified in LDFLAGS using the -L option
1602 and in CPPFLAGS using the -I option for adding library and include
1603 directories, respectively, for compiling extension modules against. This has
1604 led to the core being compiled using the values in CPPFLAGS. It also removes
1605 the need for the special-casing of both DarwinPorts and Fink for darwin since
1606 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1607 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1608 Fink, ``-I/opt/local/include`` for DarwinPorts).
1609
Brett Cannon43802422005-02-10 20:48:03 +00001610- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1611 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1612 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1613 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001615C API
1616-----
1617
Tim Petersc9d78aa2006-03-26 23:27:58 +00001618- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1619 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1620 is obtained via the ``PyObject_`` family, it must be released via the
1621 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1622 always been officially true, but when Python's small-object allocator was
1623 introduced, an attempt was made to cater to a few extension modules
1624 discovered at the time that obtained memory via ``PyObject_New`` but
1625 released it via ``PyMem_DEL``. It's years later, and if such code still
1626 exists it will fail now (probably with segfaults, but calling wrong
1627 low-level memory management functions can yield many symptoms).
1628
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001629- Added a C API for set and frozenset objects.
1630

1632
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001633- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1634 mapping argument now. This string is used as a mapping table. Byte values
1635 greater than the length of the string and 0xFFFE are treated as undefined
1636 mappings.
