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 Woutersadd19112006-07-05 11:03:49 +000028- string.Template() now correctly handles tuple-values. Previously,
29 multi-value tuples would raise an exception and single-value tuples would
30 be treated as the value they contain, instead.
31
Martin v. Löwisede77f52006-07-03 13:01:35 +000032- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
33 even if some data are received.
34
Martin v. Löwis45482392006-07-03 12:28:58 +000035- Bug #1267547: Put proper recursive setup.py call into the
36 spec file generated by bdist_rpm.

39 degrees and radians.
40
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000041- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +000042 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000043
Martin v. Löwisbd39c032006-07-03 09:44:00 +000044- Bug #1514703: Only setup canvas window in turtle when the canvas
45 is created.
46
Martin v. Löwis7596e832006-07-01 15:33:37 +000047- Bug #1513223: .close() of a _socketobj now releases the underlying
48 socket again, which then gets closed as it becomes unreferenced.
49
Thomas Hellerbde08132006-06-29 18:34:15 +000050- The '_ctypes' extension module now works when Python is configured
51 with the --without-threads option.
52
Fred Drake10497c82006-06-29 02:57:48 +000053- Bug #1504333: Make sgmllib support angle brackets in quoted
54 attribute values.
55
56- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
57 sgmllib ('[' and ']' were not accepted).
58
Georg Brandl1be63af2006-06-28 20:23:25 +000059- Fix a bug in the turtle module's end_fill function.
60
Brett Cannon53ab5b72006-06-22 16:49:14 +000061- Bug #1510580: The 'warnings' module improperly required that a Warning
62 category be either a types.ClassType and a subclass of Warning. The proper
63 check is just that it is a subclass with Warning as the documentation states.
64
Georg Brandlad29e632006-06-21 17:45:17 +000065- The compiler module now correctly compiles the new try-except-finally
66 statement (bug #1509132).
67
Neal Norwitz60373cd2006-06-22 06:30:50 +000068- The wsgiref package is now installed properly on Unix.
69
Vinay Sajip28e57612006-07-01 10:45:20 +000070- A bug was fixed in logging.config.fileConfig() which caused a crash on
71 shutdown when fileConfig() was called multiple times.
72
Gerhard Häring762fbd32006-07-02 17:48:30 +000073- The sqlite3 module did cut off data from the SQLite database at the first
74 null character before sending it to a custom converter. This has been fixed
75 now.

78-----------------
79
Martin v. Löwisee1e06d2006-07-02 18:44:00 +000080- Bug #1513646: os.access on Windows now correctly determines write
81 access, again.
82
Neal Norwitz0f8b31a2006-06-28 06:28:31 +000083- Bug #1512695: cPickle.loads could crash if it was interrupted with
84 a KeyboardInterrupt.
85
Neal Norwitza12aa882006-07-06 06:45:08 +000086- Bug #1296433: parsing XML with a non-default encoding and
87 a CharacterDataHandler could crash the interpreter in pyexpat.

90-----
91
Neal Norwitzc315a0f2006-06-27 04:28:56 +000092- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +000093 trying to be installed even though it's empty.

112Core and builtins
113-----------------
114
Georg Brandla56b9152006-06-19 06:35:54 +0000115- Patch #1507676: Error messages returned by invalid abstract object operations
116 (such as iterating over an integer) have been improved and now include the
117 type of the offending object to help with debugging.
118
Brett Cannonea3912b2006-06-13 21:46:41 +0000119- Bug #992017: A classic class that defined a __coerce__() method that returned
120 its arguments swapped would infinitely recurse and segfault the interpreter.
121
Neal Norwitz909eb122006-06-12 02:13:21 +0000122- Fix the socket tests so they can be run concurrently.
123
Neal Norwitzb9845e72006-06-12 02:11:18 +0000124- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000125 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000126
Brett Cannon22565aa2006-06-09 22:31:23 +0000127- Bug #532646: object.__call__() will continue looking for the __call__
128 attribute on objects until one without one is found. This leads to recursion
129 when you take a class and set its __call__ attribute to an instance of the
130 class. Originally fixed for classic classes, but this fix is for new-style.
131 Removes the infinite_rec_3 crasher.
132
Georg Brandl24250812006-06-09 18:45:48 +0000133- The string and unicode methods startswith() and endswith() now accept
134 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
135
Brett Cannonde3b0522006-06-08 17:00:45 +0000136- Buffer objects, at the C level, never used the char buffer
137 implementation even when the char buffer for the wrapped object was
138 explicitly requested (originally returned the read or write buffer).
139 Now a TypeError is raised if the char buffer is not present but is
140 requested.
141
Georg Brandlddbaa662006-06-04 21:56:52 +0000142- Patch #1346214: Statements like "if 0: suite" are now again optimized
143 away like they were in Python 2.4.
144
Georg Brandlb7c8f542006-05-27 12:30:25 +0000145- Builtin exceptions are now full-blown new-style classes instead of
146 instances pretending to be classes, which speeds up exception handling
147 by about 80% in comparison to 2.5a2.
148
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000149- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
150 Unicode 4.1.
151
Georg Brandlf4ef1162006-05-26 18:03:31 +0000152- Patch #921466: sys.path_importer_cache is now used to cache valid and
153 invalid file paths for the built-in import machinery which leads to
154 fewer open calls on startup.
155
Tim Peters696cf432006-05-24 21:10:40 +0000156- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
157 of-2 bases. The largest speedup is for inputs with about 1000 decimal
158 digits. Conversion from non-power-of-2 bases remains quadratic-time in
159 the number of input digits (it was and remains linear-time for bases
160 2, 4, 8, 16 and 32).
161
Tim Petersb713ec22006-05-23 18:45:30 +0000162- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
163 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
164 an integer close to ``sys.maxint``. This was repaired by patch
165 #1335972, which also gives a nice speedup.
166
Richard Jonescebbefc2006-05-23 18:28:17 +0000167- Patch #1337051: reduced size of frame objects.
168
169- PyErr_NewException now accepts a tuple of base classes as its
170 "base" parameter.
171
Richard Jones7c88dcc2006-05-23 10:37:38 +0000172- Patch #876206: function call speedup by retaining allocated frame
173 objects.
174
Georg Brandl7b90e162006-05-18 07:01:27 +0000175- Bug #1462152: file() now checks more thoroughly for invalid mode
176 strings and removes a possible "U" before passing the mode to the
177 C library function.
178
Neal Norwitz1004a532006-05-15 07:17:23 +0000179- Patch #1488312, Fix memory alignment problem on SPARC in unicode
180
Neal Norwitz373f0a72006-05-15 07:04:36 +0000181- Bug #1487966: Fix SystemError with conditional expression in assignment
182
Martin v. Löwis879768d2006-05-11 13:28:43 +0000183- WindowsError now has two error code attributes: errno, which carries
184 the error values from errno.h, and winerror, which carries the error
185 values from winerror.h. Previous versions put the winerror.h values
186 (from GetLastError()) into the errno attribute.
187
Martin v. Löwis77736712006-05-04 05:51:03 +0000188- Patch #1475845: Raise IndentationError for unexpected indent.
189
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000190- Patch #1479181: split open() and file() from being aliases for each other.
191
Tim Peters44bd9862006-06-01 13:49:23 +0000192- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
193 methods were always silently ignored by dictionaries when comparing keys.
194 They are now passed through (except when using the C API function
195 ``PyDict_GetItem()``, whose semantics did not change).
196
197- Bug #1456209: In some obscure cases it was possible for a class with a
198 custom ``__eq__()`` method to confuse dict internals when class instances
199 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
200 No, you don't have any code that did this ;-)

208
Brett Cannon6ee7d012006-06-08 16:23:04 +0000209- Change binascii.hexlify to accept a read-only buffer instead of only a char
210 buffer and actually follow its documentation.
211
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000212- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
213
Nick Coghlanc649ec52006-05-29 12:43:05 +0000214- Patch #1478788 (modified version): The functional extension module has
215 been renamed to _functools and a functools Python wrapper module added.
216 This provides a home for additional function related utilities that are
217 not specifically about functional programming. See PEP 309.
218
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000219- Patch #1493701: performance enhancements for struct module.

228
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000229- On Win32, os.listdir now supports arbitrarily-long Unicode path names
230 (up to the system limit of 32K characters).
231
232- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
233 As a result, these functions now raise WindowsError instead of OSError.
234
Tim Peters7a822da2006-05-25 21:50:17 +0000235- ``time.clock()`` on Win64 should use the high-performance Windows
236 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
237 Windows platforms).
238
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000239- Calling Tk_Init twice is refused if the first call failed as that
240 may deadlock.
241
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000242- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
243 accept it without potentially using an uninitialized pointer.
244
245- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
246 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

251
Gregory P. Smith372b5832006-06-05 18:48:21 +0000252- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
253 parameter is supplied. [SF pybsddb bug #1477863]
254
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000255- bsddb: the __len__ method of a DB object has been fixed to return correct
256 results. It could previously incorrectly return 0 in some cases.
257 Fixes SF bug 1493322 (pybsddb bug 1184012).
258
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000259- bsddb: the bsddb.dbtables Modify method now raises the proper error and
260 aborts the db transaction safely when a modifier callback fails.
261 Fixes SF python patch/bug #1408584.
262
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000263- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000264 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000265 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
266 database calls that would previously deadlock. [SF python bug #775414]
267
Vinay Sajip28e57612006-07-01 10:45:20 +0000268- Patch #1446489: add support for the ZIP64 extensions to zipfile.

297
Tim Peters43898b42006-06-14 04:09:25 +0000298- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
299 guarantee that adjacent triples in the return list always describe
300 non-adjacent blocks. Previously, a pair of matching blocks could end
301 up being described by multiple adjacent triples that formed a partition

Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000312- The wsgiref package has been added to the standard library.
313
Nick Coghlan676725d2006-06-08 13:54:49 +0000314- The functions update_wrapper() and wraps() have been added to the functools
315 module. These make it easier to copy relevant metadata from the original
316 function when writing wrapper functions.
317
Tim Petersd6a9eef2006-06-05 01:48:21 +0000318- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
319 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000320
Martin v. Löwis3f767792006-06-04 19:36:28 +0000321- Patch #1359618: Speed up charmap encoder by using a trie structure
322 for lookup.
323
Tim Petersd609b1a2006-06-02 23:22:51 +0000324- The functions in the ``pprint`` module now sort dictionaries by key
325 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
326 if and only if its display required more than one line, although that
327 wasn't documented. The new behavior increases predictability; e.g.,
328 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
329
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000330- Patch #1497027: try HTTP digest auth before basic auth in urllib2
331 (thanks for J. J. Lee).
332
Georg Brandl2b330372006-05-28 20:23:12 +0000333- Patch #1496206: improve urllib2 handling of passwords with respect to
334 default HTTP and HTTPS ports.
335
George Yoshidaf3c65de2006-05-28 16:39:09 +0000336- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
337
Bob Ippolito7298f272006-05-23 18:43:47 +0000338- Patch #1281707: speed up gzip.readline.
339
Georg Brandlb89316f2006-05-17 15:51:16 +0000340- Patch #1180296: Two new functions were added to the locale module:
341 format_string() to get the effect of "format % items" but locale-aware,
342 and currency() to format a monetary number with currency sign.
343
Georg Brandle3a25832006-05-17 14:56:04 +0000344- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
345 and several features added, such as speed and geometry control.
346
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000347- Patch #1488881: add support for external file objects in bz2 compressed
348 tarfiles.
349
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000350- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
351 stdout arguments, making it possible to redirect input and output
352 for remote debugging.
353
354- Patch #1484695: Update the tarfile module to version 0.8. This fixes
355 a couple of issues, notably handling of long file names using the
356 GNU LONGNAME extension.
357
358- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
359 new flag when ``name`` is already the name of an option flag.
360
361- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
362 package.
363
364- Patch #1472854: make the rlcompleter.Completer class usable on non-
365 UNIX platforms.
366
367- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
368
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000369- Bug #1472827: correctly escape newlines and tabs in attribute values in
370 the saxutils.XMLGenerator class.

381
Neal Norwitz58e28882006-05-19 07:00:58 +0000382- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
383
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000384- Patch #1471883: Add --enable-universalsdk.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000400What's New in Python 2.5 alpha 2?
401=================================
402
403*Release date: 27-APR-2006*
404
405Core and builtins
406-----------------
407
Thomas Heller1b046642006-04-18 18:51:06 +0000408- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
409 by converting these apis from macros into exported functions again:
410
411 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
412 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
413 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
414 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
415 PyRun_String Py_CompileString
416
Martin v. Löwis45294a92006-04-18 06:24:08 +0000417- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
418
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000419- All uses of PyStructSequence_InitType have been changed to initialize
420 the type objects only once, even if the interpreter is initialized
421 multiple times.
422
Neal Norwitz61546162006-04-14 05:20:28 +0000423- Bug #1454485, array.array('u') could crash the interpreter. This was
424 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
425 to unicode when it didn't make sense. 'u#' now requires a unicode string.
426
427- Py_UNICODE is unsigned. It was always documented as unsigned, but
428 due to a bug had a signed value in previous versions.
429
Tim Peters3a5e8b12006-04-11 01:44:07 +0000430- Patch #837242: ``id()`` of any Python object always gives a positive
431 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
432 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000433 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000434 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000435
Tim Peters3a5e8b12006-04-11 01:44:07 +0000436 def __hash__(self):
437 return id(self) # WRONG
438
439 because a hash result must be a (short) Python int but it was always
440 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000441 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000442 was always usable as a hash value before this patch. That's no longer
443 necessarily so.
444
445- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000446 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000447 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000448 #1454844)
449
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000450- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
451 involving generators that have paused outside of any ``try`` or ``with``
452 blocks. (In 2.5a1, a paused generator that was part of a reference
453 cycle could not be garbage collected, regardless of whether it was
454 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000456Extension Modules

460 is a macro.
461
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000462- Bug #1467952: os.listdir() now correctly raises an error if readdir()
463 fails with an error condition.
464
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000465- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
466
467- Bug #1117761: bsddb.*open() no longer raises an exception when using
468 the cachesize parameter.
469
470- Bug #1149413: bsddb.*open() no longer raises an exception when using
471 a temporary db (file=None) with the 'n' flag to truncate on open.
472
473- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
474 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000475
Armin Rigoa9017c32006-04-19 11:50:27 +0000476- Patch #1062014: AF_UNIX sockets under Linux have a special
477 abstract namespace that is now fully supported.
478
Anthony Baxter51bcb682006-04-05 14:51:42 +0000479Library
480-------
481
Tim Peters711bf302006-04-25 03:31:36 +0000482- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
483 a doctest to be skipped (the code is not run, and the expected output
484 or exception is ignored).
485
Nick Coghlanda2268f2006-04-24 04:37:15 +0000486- Fixed contextlib.nested to cope with exceptions being raised and
487 caught inside exit handlers.
488
Greg Wardab05edc2006-04-23 03:47:58 +0000489- Updated optparse module to Optik 1.5.1 (allow numeric constants in
490 hex, octal, or binary; add ``append_const`` action; keep going if
491 gettext cannot be imported; added ``OptionParser.destroy()`` method;
492 added ``epilog`` for better help generation).
493
Tim Peters21fbd572006-04-21 21:18:10 +0000494- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
495 called from a thread spawned as a side effect of importing a module.
496
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000497- The pydoc module now supports documenting packages contained in
498 .zip or .egg files.
499
500- The pkgutil module now has several new utility functions, such
501 as ``walk_packages()`` to support working with packages that are either
502 in the filesystem or zip files.
503
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000504- The mailbox module can now modify and delete messages from
505 mailboxes, in addition to simply reading them. Thanks to Gregory
506 K. Johnson for writing the code, and to the 2005 Google Summer of
507 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000508
Tim Petersc7605f22006-04-17 21:12:33 +0000509- The ``__del__`` method of class ``local`` in module ``_threading_local``
510 returned before accomplishing any of its intended cleanup.
511
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000512- Patch #790710: Add breakpoint command lists in pdb.
513
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000514- Patch #1063914: Add Tkinter.Misc.clipboard_get().
515
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000516- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
517
Anthony Baxtere29002c2006-04-12 12:07:31 +0000518- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
519 Windows. Bug #1469163.
520
Phillip J. Eby47032112006-04-11 01:07:43 +0000521- The warnings, linecache, inspect, traceback, site, and doctest modules
522 were updated to work correctly with modules imported from zipfiles or
523 via other PEP 302 __loader__ objects.
524
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000525- Patch #1467770: Reduce usage of subprocess._active to processes which
526 the application hasn't waited on.
527

533 direct output to an alternate file-like object.
534

536-----
537
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000538- The Makefile now has a reindent target, which runs reindent.py on
539 the library.
540

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000544
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000545- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
546 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000547 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000548 CXX from --with-cxx-main, see description in README.
549
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000550- Patch #1429775: Link extension modules with the shared libpython.
551
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000552- Fixed a libffi build problem on MIPS systems.
553
Tim Peters8931ff12006-05-13 23:28:20 +0000554- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
555 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

557
Anthony Baxter51bcb682006-04-05 14:51:42 +0000558Tests
559-----
560
Nick Coghlanda2268f2006-04-24 04:37:15 +0000561- test_contextlib now checks contextlib.nested can cope with exceptions
562 being raised and caught inside exit handlers.
563
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000564- test_cmd_line now checks operation of the -m and -c command switches
565
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000566- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
567 it separately and by hand. It also wasn't cleaning up its changes to
568 the current Decimal context.
569
Thomas Woutersabd08882006-04-26 15:53:30 +0000570- regrtest.py now has a -M option to run tests that test the new limits of
571 containers, on 64-bit architectures. Running these tests is only sensible
572 on 64-bit machines with more than two gigabytes of memory. The argument
573 passed is the maximum amount of memory for the tests to use.

582-------------
583
Tim Petersb06d28c2006-05-12 01:57:59 +0000584- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
585
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000586- PEP 343: Added Context Types section to the library reference
587 and attempted to bring other PEP 343 related documentation into
588 line with the implementation and/or python-dev discussions.
589
Tim Peters8dc73d22006-04-24 02:03:16 +0000590- Bug #1337990: clarified that ``doctest`` does not support examples
591 requiring both expected output and an exception.

Anthony Baxterebed3f62006-04-03 15:03:44 +0000597*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000598
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000599Core and builtins
600-----------------
601
Nick Coghlan43832302006-04-23 17:04:07 +0000602- PEP 338: -m command line switch now delegates to runpy.run_module
603 allowing it to support modules in packages and zipfiles
604
Martin v. Löwisc661b882006-04-20 04:54:23 +0000605- On Windows, .DLL is not an accepted file name extension for
606 extension modules anymore; extensions are only found if they
607 end in .PYD.
608
Martin v. Löwisea62d252006-04-03 10:56:49 +0000609- Bug #1421664: sys.stderr.encoding is now set to the same value as
610 sys.stdout.encoding.
611
Neal Norwitz92e212f2006-04-03 04:48:37 +0000612- __import__ accepts keyword arguments.
613
Georg Brandlccadf842006-03-31 18:54:53 +0000614- Patch #1460496: round() now accepts keyword arguments.
615
Anthony Baxter262c00a2006-03-30 10:53:17 +0000616- Fixed bug #1459029 - unicode reprs were double-escaped.
617
Hye-Shik Changd478f342006-03-23 12:32:36 +0000618- Patch #1396919: The system scope threads are reenabled on FreeBSD
619 5.4 and later versions.
620
Neal Norwitze98ccf62006-03-23 05:39:47 +0000621- Bug #1115379: Compiling a Unicode string with an encoding declaration
622 now gives a SyntaxError.
623
Georg Brandlabd1ff82006-03-18 07:59:59 +0000624- Previously, Python code had no easy way to access the contents of a
625 cell object. Now, a ``cell_contents`` attribute has been added
626 (closes patch #1170323).
627
Tim Peterscf79aac2006-03-16 01:14:46 +0000628- Patch #1123430: Python's small-object allocator now returns an arena to
629 the system ``free()`` when all memory within an arena becomes unused
630 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
631 freed. Some applications will see a drop in virtual memory size now,
632 especially long-running applications that, from time to time, temporarily
633 use a large number of small objects. Note that when Python returns an
634 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000635 platform C library will in turn return that memory to the operating system.
636 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000637 appears to be effective at least on Microsoft C and gcc-based systems.
638 Thanks to Evan Jones for hard work and patience.
639
Georg Brandl533ff6f2006-03-08 18:09:27 +0000640- Patch #1434038: property() now uses the getter's docstring if there is
641 no "doc" argument given. This makes it possible to legitimately use
642 property() as a decorator to produce a read-only property.
643
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000644- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
645 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
646 of requiring an int or long in slicing and a few other contexts, enabling
647 other objects (e.g. Numeric Python's integers) to be used as slice indices.
648
Neal Norwitz995acdf2006-03-07 05:01:00 +0000649- Fixed various bugs reported by Coverity's Prevent tool.
650
Brett Cannonbf364092006-03-01 04:25:17 +0000651- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
652 new exception base class, BaseException, which has a new message attribute.
653 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
654 Raising a string exception now raises a DeprecationWarning.
655
Thomas Woutersfb609f42006-02-28 16:37:25 +0000656- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
657 explicitly relative, using 'from .module import name' to mean 'from the same
658 package as this module is in. Imports without dots still default to the
659 old relative-then-absolute, unless 'from __future__ import
660 absolute_import' is used.
661
Brett Cannona7446e32006-02-27 23:39:10 +0000662- Properly check if 'warnings' raises an exception (usually when a filter set
663 to "error" is triggered) when raising a warning for raising string
664 exceptions.
665
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000666- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000667 The name was removed from Include/code.h.
668
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000669- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000670
Guido van Rossum1968ad32006-02-25 22:38:04 +0000671- Patch 1433928:
672 - The copy module now "copies" function objects (as atomic objects).
673 - dict.__getitem__ now looks for a __missing__ hook before raising
674 KeyError.
675
Tim Peters84ef21c2006-02-28 20:39:06 +0000676- PEP 343: with statement implemented. Needs ``from __future__ import
677 with_statement``. Use of 'with' as a variable will generate a warning.
678 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000679 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000680 The following objects have __context__ methods:
681 - The built-in file type.
682 - The thread.LockType type.
683 - The following types defined by the threading module:
684 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
685 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000686
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000687- Fix the encodings package codec search function to only search
688 inside its own package. Fixes problem reported in patch #1433198.
689
690 Note: Codec packages should implement and register their own
691 codec search function. PEP 100 has the details.
692
Tim Peters9ea89d22006-06-04 03:26:02 +0000693- PEP 353: Using ``Py_ssize_t`` as the index type.
694
695- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
696 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
697 now allow Python to make use of memory blocks exceeding 2**32 bytes for
698 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
699 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000700
Neal Norwitzfc76d632006-01-10 06:03:13 +0000701- Patch #1400181, fix unicode string formatting to not use the locale.
702 This is how string objects work. u'%f' could use , instead of .
703 for the decimal point. Now both strings and unicode always use periods.
704
Neal Norwitz671b9e32006-01-09 07:07:12 +0000705- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
706 configure would break checking curses.h.
707
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000708- Bug #959576: The pwd module is now builtin. This allows Python to be
709 built on UNIX platforms without $HOME set.
710
Neal Norwitzc10978f2005-12-19 06:07:16 +0000711- Bug #1072182, fix some potential problems if characters are signed.
712
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000713- Bug #889500, fix line number on SyntaxWarning for global declarations.
714
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000715- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
716
Neal Norwitze7214a12005-12-18 05:03:17 +0000717- Support for converting hex strings to floats no longer works.
718 This was not portable. float('0x3') now raises a ValueError.
719
Barry Warsaw2a38a862005-12-18 01:27:35 +0000720- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000721 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000722 is now displayed in interactive prompt banner.
723
Georg Brandlfa166682005-12-17 21:45:17 +0000724- Implementation of PEP 341 - Unification of try/except and try/finally.
725 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000726 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000727
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000728- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
729 now encodes backslash correctly.
730
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000731- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
732
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000733- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000734 and long longs.
735
Neal Norwitz67715f02005-11-09 06:59:35 +0000736- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000737 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000738 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000739
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000740- Replaced most Unicode charmap codecs with new ones using the
741 new Unicode translate string feature in the builtin charmap
742 codec; the codecs were created from the mapping tables available
743 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
744 encodings now include a mapping for the Apple logo)
745
Tim Peterse3547fd2005-12-16 23:13:57 +0000746- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000747
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000748- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000749
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000750- A new AST parser implementation was completed. The abstract
751 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000752 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000753
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000754- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000755 The following code now raises a SyntaxError: foo(a = i for i in range(10))
756
Neal Norwitz708e51a2005-10-03 04:48:15 +0000757- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
758
Neal Norwitz11bd1192005-10-03 00:54:56 +0000759- SF Bug #887946: fix segfault when redirecting stdin from a directory.
760 Provide a warning when a directory is passed on the command line.
761
Neal Norwitz40d37812005-10-02 01:48:49 +0000762- Fix segfault with invalid coding.
763
764- SF bug #772896: unknown encoding results in MemoryError.
765
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000766- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000767 supported a __len__() method which evaluated to False when the iterator
768 was empty.
769
Guido van Rossum630db602005-09-20 18:49:54 +0000770- On 64-bit platforms, when __len__() returns a value that cannot be
771 represented as a C int, raise OverflowError.
772
Skip Montanarof8948ca2005-09-19 03:54:46 +0000773- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000774 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000775
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000776- SF bug #893549: parsing keyword arguments was broken with a few format
777 codes.
778
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000779- Changes donated by Elemental Security to make it work on AIX 5.3
780 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
781 bug #105470: test_pwd fails on 64bit system (Opteron).
782
Guido van Rossum539c6622005-09-14 17:49:54 +0000783- Changes donated by Elemental Security to make it work on HP-UX 11 on
784 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
785
Georg Brandl4550b8d2005-08-26 06:43:52 +0000786- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000787 (fixes bug #1119418).
788
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000789- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
790
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000791- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
792 exceptions that cause a function to exit.
793
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000794- The implementation of set() and frozenset() was revised to use its
795 own internal data structure. Memory consumption is reduced by 1/3
796 and there are modest speed-ups as well. The API is unchanged.
797
Tim Petersde7990b2005-07-17 23:45:23 +0000798- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
799
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000800- SF bug #1229429: PyObject_CallMethod failed to decrement some
801 reference counts in some error exit cases.
802
Tim Petersecc6e6a2005-07-10 22:30:55 +0000803- SF bug #1185883: Python's small-object memory allocator took over
804 a block managed by the platform C library whenever a realloc specified
805 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000806 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000807 portable way to copy data from the C-managed block into Python's
808 small-object space without risking a memory fault. Python's small-object
809 realloc now leaves such blocks under the control of the platform C
810 realloc.
811
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000812- SF bug #1232517: An overflow error was not detected properly when
813 attempting to convert a large float to an int in os.utime().
814
Raymond Hettinger3296e692005-06-29 23:29:56 +0000815- SF bug #1224347: hex longs now print with lowercase letters just
816 like their int counterparts.
817
Michael W. Hudson188d4362005-06-20 16:52:57 +0000818- SF bug #1163563: the original fix for bug #1010677 ("thread Module
819 Breaks PyGILState_Ensure()") broke badly in the case of multiple
820 interpreter states; back out that fix and do a better job (see
821 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
822 for a longer write-up of the problem).
823
Michael W. Hudsondf888462005-06-03 14:41:55 +0000824- SF patch #1180995: marshal now uses a binary format by default when
825 serializing floats.
826
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000827- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
828 the routines that promise to produce IEEE 754 binary representations
829 of floats now simply copy bytes around.
830
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000831- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
832 278.
833
Brett Cannonc3647ac2005-04-26 03:45:26 +0000834- patch #1109424: int, long, float, complex, and unicode now check for the
835 proper magic slot for type conversions when subclassed. Previously the
836 magic slot was ignored during conversion. Semantics now match the way
837 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000838 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000839 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000840 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000841
Barry Warsawc8d907c2005-04-19 23:43:40 +0000842- Descriptors defined in C with a PyGetSetDef structure, where the setter is
843 NULL, now raise an AttributeError when attempting to set or delete the
844 attribute. Previously a TypeError was raised, but this was inconsistent
845 with the equivalent pure-Python implementation.
846
Michael W. Hudson774479c2005-04-18 08:46:17 +0000847- It is now safe to call PyGILState_Release() before
848 PyEval_InitThreads() (note that if there is reason to believe there
849 are multiple threads around you still must call PyEval_InitThreads()
850 before using the Python API; this fix is for extension modules that
851 have no way of knowing if Python is multi-threaded yet).
852
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000853- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
854 disabled caused a crash.
855
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000856- Bug #1165306: instancemethod_new allowed the creation of a method
857 with im_class == im_self == NULL, which caused a crash when called.
858
Tim Petersecc6e6a2005-07-10 22:30:55 +0000859- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000860 fixes the crash seen in bug #1165761
861
Raymond Hettinger96229b12005-03-11 06:49:40 +0000862- Added two new builtins, any() and all().
863
Brett Cannon409d8f22005-03-05 06:47:57 +0000864- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000865 (e.g., ``class C(): pass`` is no longer a syntax error).
866 Patch #1176012 added support to the 'parser' module and 'compiler' package
867 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000868
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000869- Patch #1115086: Support PY_LONGLONG in structmember.
870
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000871- Bug #1155938: new style classes did not check that __init__() was
872 returning None.
873
Tim Petersecc6e6a2005-07-10 22:30:55 +0000874- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000875 ('\') with a specific error message.
876
Martin v. Löwisff232d72005-03-03 09:24:38 +0000877- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
878
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000879- Bug #1124295: the __name__ attribute of file objects was
880 inadvertently made inaccessible in restricted mode.
881
Tim Petersecc6e6a2005-07-10 22:30:55 +0000882- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000883 an ferror() call.
884
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000885- min() and max() now support key= arguments with the same meaning as in
886 list.sort().
887
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000888- The peephole optimizer now performs simple constant folding in expressions:
889 (2+3) --> (5).
890
Raymond Hettingera422c342005-01-11 03:03:27 +0000891- set and frozenset objects can now be marshalled. SF #1098985.
892
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000893- Bug #1077106: Poor argument checking could cause memory corruption
894 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000895
Jeremy Hyltonab630502005-02-04 18:44:06 +0000896- The parser did not complain about future statements in illegal
897 positions. It once again reports a syntax error if a future
898 statement occurs after anything other than a doc string.
899
Neil Schemenauercf52c072005-08-12 17:34:58 +0000900- Change the %s format specifier for str objects so that it returns a
901 unicode instance if the argument is not an instance of basestring and
902 calling __str__ on the argument returns a unicode instance.
903
Tim Petersf4e69282006-02-27 17:15:31 +0000904- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
905 current thread state when the auto-GIL-state machinery knows about
906 it (since the thread state is being deleted, continuing to remember it
907 can't help, but can hurt if another thread happens to get created with
908 the same thread id).

1098-------
1099
Nick Coghlan43832302006-04-23 17:04:07 +00001100- PEP 338: new module runpy defines a run_module function to support
1101 executing modules which provide access to source code or a code object
1102 via the PEP 302 import mechanisms.
1103
Anthony Baxter93f5b932006-04-03 08:05:07 +00001104- The email module's parsedate_tz function now sets the daylight savings

1112 in attribute values.
1113
Anthony Baxterc51ee692006-04-01 00:57:31 +00001114- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001115 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001116 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001117 module will not be built.
1118
Tim Petersc17976e2006-04-01 00:26:53 +00001119- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1120 aren't officially supported here, and trying to use them will probably
1121 raise an exception some day. But dicts have been allowed, and "mostly
1122 worked", so support for them won't go away without warning.
1123
Georg Brandl338ef7d2006-03-31 18:42:16 +00001124- Bug #1445068: getpass.getpass() can now be given an explicit stream
1125 argument to specify where to write the prompt.
1126
Georg Brandl22ec80b2006-03-31 18:25:44 +00001127- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1142
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001143- email 4.0 package now integrated. This is largely the same as the email 3.0
1144 package that was included in Python 2.3, except that PEP 8 module names are
1145 now used (e.g. mail.message instead of email.Message). The MIME classes
1146 have been moved to a subpackage (e.g. email.mime.text instead of
1147 email.MIMEText). The old names are still supported for now. Several
1148 deprecated Message methods have been removed and lots of bugs have been
1149 fixed. More details can be found in the email package documentation.
1150
Walter Dörwald40108c92006-03-27 08:15:44 +00001151- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1152 (a subclass of tuple) that provides incremental decoders and encoders
1153 (a way to use stateful codecs without the stream API). Python functions
1154 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1155 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1156 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001157
Walter Dörwald067db482006-03-15 22:17:27 +00001158- Patch #1359365: Calling next() on a closed StringIO.String object raises
1159 a ValueError instead of a StopIteration now (like file and cString.String do).
1160 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1161 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001162
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001163- A regrtest option -w was added to re-run failed tests in verbose mode.

1166 interpreter to exit.
1167
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001168- The function get_count() has been added to the gc module, and gc.collect()
1169 grew an optional 'generation' argument.
1170
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001171- A library msilib to generate Windows Installer files, and a distutils
1172 command bdist_msi have been added.
1173
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001174- PEP 343: new module contextlib.py defines decorator @contextmanager

1239
1240 "The consensus of researchers in this area (at least as
1241 expressed at the NIST Hash Function Workshop 10/31/05),
1242 is that SHA-256 is a good choice for the time being, but
1243 that research should continue, and other alternatives may
1244 arise from this research. The larger SHA's also seem OK."

1432 dictates.
1433 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001434 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001435 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001436 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1437 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001438 + reader now allows \r characters to be quoted (previously it only allowed
1439 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001440 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001441 + Dialect classes passed to the module are no longer instantiated by
1442 the module before being parsed (the former validation scheme required
1443 this, but the mechanism was unreliable).
1444 + The dialect registry now contains instances of the internal
1445 C-coded dialect type, rather than references to python objects.
1446 + the internal c-coded dialect type is now immutable.
1447 + register_dialect now accepts the same keyword dialect specifications
1448 as the reader and writer, allowing the user to register dialects
1449 without first creating a dialect class.
1450 + a configurable limit to the size of parsed fields has been added -
1451 previously, an unmatched quote character could result in the entire
1452 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001453 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001454 the parser field size limit (returning the former limit). The initial
1455 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001456 + A line_num attribute has been added to the reader object, which tracks
1457 the number of lines read from the source iterator. This is not
1458 the same as the number of records returned, as records can span
1459 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001460 + reader and writer objects were not being registered with the cyclic-GC.
1461 This has been fixed.
1462
Brett Cannone6539c42005-01-08 02:43:53 +00001463- _DummyThread objects in the threading module now delete self.__block that is
1464 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1465 lock primitives tend to be limited in number and thus should not be wasted on
1466 a _DummyThread object. Fixes bug #1089632.
1467
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001468- The imghdr module now detects Exif files.
1469
Raymond Hettinger6065d322004-12-20 23:51:53 +00001470- StringIO.truncate() now correctly adjusts the size attribute.
1471 (Bug #951915).
1472
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001473- locale.py now uses an updated locale alias table (built using
1474 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1475 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001476 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001477
Raymond Hettinger3557f422004-12-07 12:02:02 +00001478- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1479
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001480- the pickle module no longer accepts the deprecated None option in the
1481 args tuple returned by __reduce__().
1482
Brett Cannon84667c02004-12-07 03:25:18 +00001483- optparse now optionally imports gettext. This allows its use in setup.py.
1484
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001485- the pickle module no longer uses the deprecated bin parameter.
1486
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001487- the shelve module no longer uses the deprecated binary parameter.
1488
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001489- the pstats module no longer uses the deprecated ignore() method.
1490
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001491- the filecmp module no longer uses the deprecated use_statcache argument.
1492
Raymond Hettinger664347b2004-12-04 21:21:53 +00001493- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1494 extended or overridden by subclasses. Formerly, the subclassed method would
1495 be ignored by the rest of the module. (Bug #1078905).
1496
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001497- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001498 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001499
Walter Dörwald36733692004-12-22 12:50:50 +00001500- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1501 once when a size argument is given. This prevents a buffer overflow in the
1502 tokenizer with very long source lines.
1503
Barry Warsaw538561e2006-01-01 21:48:54 +00001504- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1505 immediately after creating the object, without any intervening
1506 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001507
Skip Montanaro05885812005-01-16 20:48:27 +00001508- The reconvert.quote function can now emit triple-quoted strings. The
1509 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001510
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001511- ``UserString.MutableString`` now supports negative indices in
1512 ``__setitem__`` and ``__delitem__``
1513
Greg Ward40407942005-03-05 02:53:17 +00001514- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1515 correctly.
1516
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001517- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1518 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1519 character even if the user has passed a size parameter to get a proper
1520 line ending. Remove the special handling of a "\r\n" that has been split
1521 between two lines.
1522
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001523- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1524 about illegal code points. The codec now supports PEP 293 style error
1525 handlers.
1526
Walter Dörwald78a78b02005-09-01 12:04:29 +00001527- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001528 from the input stream, so that the output is a byte string in the correct
1529 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001530
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001531- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1532 considering it exactly like a '*'.
1533
Walter Dörwald007f8df2005-10-09 19:42:27 +00001534- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1535 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001536
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001537- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1538
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001539- Patch #1413711: Certain patterns of differences were making difflib
1540 touch the recursion limit.
1541
Walter Dörwald58917a62006-03-31 15:26:22 +00001542- Bug #947906: An object oriented interface has been added to the calendar
1543 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001544 called as a script (e.g. via ``python -mcalendar``). Localized month and
1545 weekday names can be ouput (even if an exotic encoding is used) using
1546 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001547

1549-----
1550
Neal Norwitz602d3392006-03-31 08:21:40 +00001551- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1552 by using -mieee gcc option.
1553
Martin v. Löwis86d66262006-02-17 08:40:11 +00001554- Patch #1432345: Make python compile on DragonFly.
1555
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001556- Build support for Win64-AMD64 was added.
1557
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001558- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1559
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001560- Patch #881820: look for openpty and forkpty also in libbsd.
1561
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001562- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1563 The zlib module is now builtin on Windows.
1564
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001565- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1566
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001567- Bug #1189330: configure did not correctly determine the necessary
1568 value of LINKCC if python was built with GCC 4.0.
1569
Trent Mick8321b422005-07-26 02:29:21 +00001570- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1571 vulnerability in zlib 1.2.1 and 1.2.2.
1572
Brett Cannon08cd5982005-04-24 22:26:38 +00001573- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1574 flags that change binary compatibility. Changes were also made to
1575 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001576 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001577
Bob Ippolitoed233462005-03-29 13:47:59 +00001578- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1579 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1580 no longer exists). This configure patch makes things right.
1581
Martin v. Löwise2713be2005-03-08 15:03:08 +00001582- Bug #1158607: Build with --disable-unicode again.
1583
Brett Cannon46d96232005-02-16 00:07:19 +00001584- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1585 defined. Discovered as a result of not being able to build on OS X.
1586
Brett Cannon516592f2004-12-07 00:42:59 +00001587- setup.py now uses the directories specified in LDFLAGS using the -L option
1588 and in CPPFLAGS using the -I option for adding library and include
1589 directories, respectively, for compiling extension modules against. This has
1590 led to the core being compiled using the values in CPPFLAGS. It also removes
1591 the need for the special-casing of both DarwinPorts and Fink for darwin since
1592 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1593 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1594 Fink, ``-I/opt/local/include`` for DarwinPorts).
1595
Brett Cannon43802422005-02-10 20:48:03 +00001596- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1597 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1598 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1599 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001601C API
1602-----
1603
Tim Petersc9d78aa2006-03-26 23:27:58 +00001604- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1605 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1606 is obtained via the ``PyObject_`` family, it must be released via the
1607 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1608 always been officially true, but when Python's small-object allocator was
1609 introduced, an attempt was made to cater to a few extension modules
1610 discovered at the time that obtained memory via ``PyObject_New`` but
1611 released it via ``PyMem_DEL``. It's years later, and if such code still
1612 exists it will fail now (probably with segfaults, but calling wrong
1613 low-level memory management functions can yield many symptoms).
1614
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001615- Added a C API for set and frozenset objects.
1616

1618
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001619- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1620 mapping argument now. This string is used as a mapping table. Byte values
1621 greater than the length of the string and 0xFFFE are treated as undefined
1622 mappings.
