13-----------------
14
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000015- Bug #927248: Recursive method-wrapper objects can now safely
16 be released.
17

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.
37

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.
76

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.
88

91
Martin v. Löwis88ef6372006-07-06 06:55:58 +000092- Bug #1517388: sqlite3.dll is now installed on Windows independent
93 of Tcl/Tk.
94
Neal Norwitzc315a0f2006-06-27 04:28:56 +000095- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +000096 trying to be installed even though it's empty.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000110What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000111================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000112
Anthony Baxterd1136802006-06-19 12:04:15 +0000113*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000114
115Core and builtins
116-----------------
117
Georg Brandla56b9152006-06-19 06:35:54 +0000118- Patch #1507676: Error messages returned by invalid abstract object operations
119 (such as iterating over an integer) have been improved and now include the
120 type of the offending object to help with debugging.
121
Brett Cannonea3912b2006-06-13 21:46:41 +0000122- Bug #992017: A classic class that defined a __coerce__() method that returned
123 its arguments swapped would infinitely recurse and segfault the interpreter.
124
Neal Norwitz909eb122006-06-12 02:13:21 +0000125- Fix the socket tests so they can be run concurrently.
126
Neal Norwitzb9845e72006-06-12 02:11:18 +0000127- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000128 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000129
Brett Cannon22565aa2006-06-09 22:31:23 +0000130- Bug #532646: object.__call__() will continue looking for the __call__
131 attribute on objects until one without one is found. This leads to recursion
132 when you take a class and set its __call__ attribute to an instance of the
133 class. Originally fixed for classic classes, but this fix is for new-style.
134 Removes the infinite_rec_3 crasher.
135
Georg Brandl24250812006-06-09 18:45:48 +0000136- The string and unicode methods startswith() and endswith() now accept
137 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
138
Brett Cannonde3b0522006-06-08 17:00:45 +0000139- Buffer objects, at the C level, never used the char buffer
140 implementation even when the char buffer for the wrapped object was
141 explicitly requested (originally returned the read or write buffer).
142 Now a TypeError is raised if the char buffer is not present but is
143 requested.
144
Georg Brandlddbaa662006-06-04 21:56:52 +0000145- Patch #1346214: Statements like "if 0: suite" are now again optimized
146 away like they were in Python 2.4.
147
Georg Brandlb7c8f542006-05-27 12:30:25 +0000148- Builtin exceptions are now full-blown new-style classes instead of
149 instances pretending to be classes, which speeds up exception handling
150 by about 80% in comparison to 2.5a2.
151
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000152- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
153 Unicode 4.1.
154
Georg Brandlf4ef1162006-05-26 18:03:31 +0000155- Patch #921466: sys.path_importer_cache is now used to cache valid and
156 invalid file paths for the built-in import machinery which leads to
157 fewer open calls on startup.
158
Tim Peters696cf432006-05-24 21:10:40 +0000159- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
160 of-2 bases. The largest speedup is for inputs with about 1000 decimal
161 digits. Conversion from non-power-of-2 bases remains quadratic-time in
162 the number of input digits (it was and remains linear-time for bases
163 2, 4, 8, 16 and 32).
164
Tim Petersb713ec22006-05-23 18:45:30 +0000165- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
166 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
167 an integer close to ``sys.maxint``. This was repaired by patch
168 #1335972, which also gives a nice speedup.
169
Richard Jonescebbefc2006-05-23 18:28:17 +0000170- Patch #1337051: reduced size of frame objects.
171
172- PyErr_NewException now accepts a tuple of base classes as its
173 "base" parameter.
174
Richard Jones7c88dcc2006-05-23 10:37:38 +0000175- Patch #876206: function call speedup by retaining allocated frame
176 objects.
177
Georg Brandl7b90e162006-05-18 07:01:27 +0000178- Bug #1462152: file() now checks more thoroughly for invalid mode
179 strings and removes a possible "U" before passing the mode to the
180 C library function.
181
Neal Norwitz1004a532006-05-15 07:17:23 +0000182- Patch #1488312, Fix memory alignment problem on SPARC in unicode
183
Neal Norwitz373f0a72006-05-15 07:04:36 +0000184- Bug #1487966: Fix SystemError with conditional expression in assignment
185
Martin v. Löwis879768d2006-05-11 13:28:43 +0000186- WindowsError now has two error code attributes: errno, which carries
187 the error values from errno.h, and winerror, which carries the error
188 values from winerror.h. Previous versions put the winerror.h values
189 (from GetLastError()) into the errno attribute.
190
Martin v. Löwis77736712006-05-04 05:51:03 +0000191- Patch #1475845: Raise IndentationError for unexpected indent.
192
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000193- Patch #1479181: split open() and file() from being aliases for each other.
194
Tim Peters44bd9862006-06-01 13:49:23 +0000195- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
196 methods were always silently ignored by dictionaries when comparing keys.
197 They are now passed through (except when using the C API function
198 ``PyDict_GetItem()``, whose semantics did not change).
199
200- Bug #1456209: In some obscure cases it was possible for a class with a
201 custom ``__eq__()`` method to confuse dict internals when class instances
202 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
203 No, you don't have any code that did this ;-)

211
Brett Cannon6ee7d012006-06-08 16:23:04 +0000212- Change binascii.hexlify to accept a read-only buffer instead of only a char
213 buffer and actually follow its documentation.
214
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000215- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
216
Nick Coghlanc649ec52006-05-29 12:43:05 +0000217- Patch #1478788 (modified version): The functional extension module has
218 been renamed to _functools and a functools Python wrapper module added.
219 This provides a home for additional function related utilities that are
220 not specifically about functional programming. See PEP 309.
221
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000222- Patch #1493701: performance enhancements for struct module.

230 enabled builds on Windows and systems with Posix threads support.
231
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000232- On Win32, os.listdir now supports arbitrarily-long Unicode path names
233 (up to the system limit of 32K characters).
234
235- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
236 As a result, these functions now raise WindowsError instead of OSError.
237
Tim Peters7a822da2006-05-25 21:50:17 +0000238- ``time.clock()`` on Win64 should use the high-performance Windows
239 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
240 Windows platforms).
241
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000242- Calling Tk_Init twice is refused if the first call failed as that
243 may deadlock.
244
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000245- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
246 accept it without potentially using an uninitialized pointer.
247
248- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
249 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
250 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000251
Gregory P. Smith372b5832006-06-05 18:48:21 +0000252- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.

254
Gregory P. Smith372b5832006-06-05 18:48:21 +0000255- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
256 parameter is supplied. [SF pybsddb bug #1477863]
257
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000258- bsddb: the __len__ method of a DB object has been fixed to return correct
259 results. It could previously incorrectly return 0 in some cases.
260 Fixes SF bug 1493322 (pybsddb bug 1184012).
261
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000262- bsddb: the bsddb.dbtables Modify method now raises the proper error and
263 aborts the db transaction safely when a modifier callback fails.
264 Fixes SF python patch/bug #1408584.
265
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000266- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000267 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000268 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
269 database calls that would previously deadlock. [SF python bug #775414]
270

300
Tim Peters43898b42006-06-14 04:09:25 +0000301- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
302 guarantee that adjacent triples in the return list always describe
303 non-adjacent blocks. Previously, a pair of matching blocks could end
304 up being described by multiple adjacent triples that formed a partition

Greg Ward7f547402006-06-11 00:40:49 +0000312- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
313 clarify docs.
314
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000315- The wsgiref package has been added to the standard library.
316
Nick Coghlan676725d2006-06-08 13:54:49 +0000317- The functions update_wrapper() and wraps() have been added to the functools
318 module. These make it easier to copy relevant metadata from the original
319 function when writing wrapper functions.
320
Tim Petersd6a9eef2006-06-05 01:48:21 +0000321- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
322 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000323
Martin v. Löwis3f767792006-06-04 19:36:28 +0000324- Patch #1359618: Speed up charmap encoder by using a trie structure
325 for lookup.
326
Tim Petersd609b1a2006-06-02 23:22:51 +0000327- The functions in the ``pprint`` module now sort dictionaries by key
328 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
329 if and only if its display required more than one line, although that
330 wasn't documented. The new behavior increases predictability; e.g.,
331 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
332
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000333- Patch #1497027: try HTTP digest auth before basic auth in urllib2
334 (thanks for J. J. Lee).
335
Georg Brandl2b330372006-05-28 20:23:12 +0000336- Patch #1496206: improve urllib2 handling of passwords with respect to
337 default HTTP and HTTPS ports.
338
George Yoshidaf3c65de2006-05-28 16:39:09 +0000339- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
340
Bob Ippolito7298f272006-05-23 18:43:47 +0000341- Patch #1281707: speed up gzip.readline.
342
Georg Brandlb89316f2006-05-17 15:51:16 +0000343- Patch #1180296: Two new functions were added to the locale module:
344 format_string() to get the effect of "format % items" but locale-aware,
345 and currency() to format a monetary number with currency sign.
346
Georg Brandle3a25832006-05-17 14:56:04 +0000347- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
348 and several features added, such as speed and geometry control.
349
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000350- Patch #1488881: add support for external file objects in bz2 compressed
351 tarfiles.
352
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000353- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
354 stdout arguments, making it possible to redirect input and output
355 for remote debugging.
356
357- Patch #1484695: Update the tarfile module to version 0.8. This fixes
358 a couple of issues, notably handling of long file names using the
359 GNU LONGNAME extension.
360
361- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
362 new flag when ``name`` is already the name of an option flag.
363
364- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
365 package.
366
367- Patch #1472854: make the rlcompleter.Completer class usable on non-
368 UNIX platforms.
369
370- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
371
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000372- Bug #1472827: correctly escape newlines and tabs in attribute values in
373 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000403What's New in Python 2.5 alpha 2?
404=================================
405
406*Release date: 27-APR-2006*
407
408Core and builtins
409-----------------
410
Thomas Heller1b046642006-04-18 18:51:06 +0000411- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
412 by converting these apis from macros into exported functions again:
413
414 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
415 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
416 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
417 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
418 PyRun_String Py_CompileString
419
Martin v. Löwis45294a92006-04-18 06:24:08 +0000420- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
421
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000422- All uses of PyStructSequence_InitType have been changed to initialize
423 the type objects only once, even if the interpreter is initialized
424 multiple times.
425
Neal Norwitz61546162006-04-14 05:20:28 +0000426- Bug #1454485, array.array('u') could crash the interpreter. This was
427 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
428 to unicode when it didn't make sense. 'u#' now requires a unicode string.
429
430- Py_UNICODE is unsigned. It was always documented as unsigned, but
431 due to a bug had a signed value in previous versions.
432
Tim Peters3a5e8b12006-04-11 01:44:07 +0000433- Patch #837242: ``id()`` of any Python object always gives a positive
434 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
435 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000436 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000437 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000438
Tim Peters3a5e8b12006-04-11 01:44:07 +0000439 def __hash__(self):
440 return id(self) # WRONG
441
442 because a hash result must be a (short) Python int but it was always
443 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000444 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000445 was always usable as a hash value before this patch. That's no longer
446 necessarily so.
447
448- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000449 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000450 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000451 #1454844)
452
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000453- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
454 involving generators that have paused outside of any ``try`` or ``with``
455 blocks. (In 2.5a1, a paused generator that was part of a reference
456 cycle could not be garbage collected, regardless of whether it was
457 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000459Extension Modules

466 fails with an error condition.
467
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000468- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
469
470- Bug #1117761: bsddb.*open() no longer raises an exception when using
471 the cachesize parameter.
472
473- Bug #1149413: bsddb.*open() no longer raises an exception when using
474 a temporary db (file=None) with the 'n' flag to truncate on open.
475
476- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
477 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000478
Armin Rigoa9017c32006-04-19 11:50:27 +0000479- Patch #1062014: AF_UNIX sockets under Linux have a special
480 abstract namespace that is now fully supported.
481
Anthony Baxter51bcb682006-04-05 14:51:42 +0000482Library

484
Tim Peters711bf302006-04-25 03:31:36 +0000485- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
486 a doctest to be skipped (the code is not run, and the expected output
487 or exception is ignored).
488
Nick Coghlanda2268f2006-04-24 04:37:15 +0000489- Fixed contextlib.nested to cope with exceptions being raised and
490 caught inside exit handlers.
491
Greg Wardab05edc2006-04-23 03:47:58 +0000492- Updated optparse module to Optik 1.5.1 (allow numeric constants in
493 hex, octal, or binary; add ``append_const`` action; keep going if
494 gettext cannot be imported; added ``OptionParser.destroy()`` method;
495 added ``epilog`` for better help generation).
496
Tim Peters21fbd572006-04-21 21:18:10 +0000497- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
498 called from a thread spawned as a side effect of importing a module.
499
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000500- The pydoc module now supports documenting packages contained in
501 .zip or .egg files.
502
503- The pkgutil module now has several new utility functions, such
504 as ``walk_packages()`` to support working with packages that are either
505 in the filesystem or zip files.
506
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000507- The mailbox module can now modify and delete messages from
508 mailboxes, in addition to simply reading them. Thanks to Gregory
509 K. Johnson for writing the code, and to the 2005 Google Summer of
510 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000511
Tim Petersc7605f22006-04-17 21:12:33 +0000512- The ``__del__`` method of class ``local`` in module ``_threading_local``
513 returned before accomplishing any of its intended cleanup.
514
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000515- Patch #790710: Add breakpoint command lists in pdb.
516
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000517- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000519- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
520
Anthony Baxtere29002c2006-04-12 12:07:31 +0000521- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
522 Windows. Bug #1469163.
523
Phillip J. Eby47032112006-04-11 01:07:43 +0000524- The warnings, linecache, inspect, traceback, site, and doctest modules
525 were updated to work correctly with modules imported from zipfiles or
526 via other PEP 302 __loader__ objects.
527
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000528- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis4be4e652006-04-17 19:25:49 +0000541- The Makefile now has a reindent target, which runs reindent.py on
542 the library.
543

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000548- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
549 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000550 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000551 CXX from --with-cxx-main, see description in README.
552
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000553- Patch #1429775: Link extension modules with the shared libpython.

Tim Peters8931ff12006-05-13 23:28:20 +0000557- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
558 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

560
Anthony Baxter51bcb682006-04-05 14:51:42 +0000561Tests

563
Nick Coghlanda2268f2006-04-24 04:37:15 +0000564- test_contextlib now checks contextlib.nested can cope with exceptions
565 being raised and caught inside exit handlers.
566
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000567- test_cmd_line now checks operation of the -m and -c command switches
568
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000569- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
570 it separately and by hand. It also wasn't cleaning up its changes to
571 the current Decimal context.
572
Thomas Woutersabd08882006-04-26 15:53:30 +0000573- regrtest.py now has a -M option to run tests that test the new limits of
574 containers, on 64-bit architectures. Running these tests is only sensible
575 on 64-bit machines with more than two gigabytes of memory. The argument
576 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +0000587- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
588
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000589- PEP 343: Added Context Types section to the library reference
590 and attempted to bring other PEP 343 related documentation into
591 line with the implementation and/or python-dev discussions.
592
Tim Peters8dc73d22006-04-24 02:03:16 +0000593- Bug #1337990: clarified that ``doctest`` does not support examples

Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000601
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000602Core and builtins

604
Nick Coghlan43832302006-04-23 17:04:07 +0000605- PEP 338: -m command line switch now delegates to runpy.run_module
606 allowing it to support modules in packages and zipfiles
607
Martin v. Löwisc661b882006-04-20 04:54:23 +0000608- On Windows, .DLL is not an accepted file name extension for
609 extension modules anymore; extensions are only found if they
610 end in .PYD.
611
Martin v. Löwisea62d252006-04-03 10:56:49 +0000612- Bug #1421664: sys.stderr.encoding is now set to the same value as
613 sys.stdout.encoding.
614
Neal Norwitz92e212f2006-04-03 04:48:37 +0000615- __import__ accepts keyword arguments.

623
Neal Norwitze98ccf62006-03-23 05:39:47 +0000624- Bug #1115379: Compiling a Unicode string with an encoding declaration
625 now gives a SyntaxError.
626
Georg Brandlabd1ff82006-03-18 07:59:59 +0000627- Previously, Python code had no easy way to access the contents of a
628 cell object. Now, a ``cell_contents`` attribute has been added
629 (closes patch #1170323).
630
Tim Peterscf79aac2006-03-16 01:14:46 +0000631- Patch #1123430: Python's small-object allocator now returns an arena to
632 the system ``free()`` when all memory within an arena becomes unused
633 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
634 freed. Some applications will see a drop in virtual memory size now,
635 especially long-running applications that, from time to time, temporarily
636 use a large number of small objects. Note that when Python returns an
637 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000638 platform C library will in turn return that memory to the operating system.
639 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000640 appears to be effective at least on Microsoft C and gcc-based systems.
641 Thanks to Evan Jones for hard work and patience.
642
Georg Brandl533ff6f2006-03-08 18:09:27 +0000643- Patch #1434038: property() now uses the getter's docstring if there is
644 no "doc" argument given. This makes it possible to legitimately use
645 property() as a decorator to produce a read-only property.
646
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000647- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
648 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
649 of requiring an int or long in slicing and a few other contexts, enabling
650 other objects (e.g. Numeric Python's integers) to be used as slice indices.
651
Neal Norwitz995acdf2006-03-07 05:01:00 +0000652- Fixed various bugs reported by Coverity's Prevent tool.
653
Brett Cannonbf364092006-03-01 04:25:17 +0000654- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
655 new exception base class, BaseException, which has a new message attribute.
656 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
657 Raising a string exception now raises a DeprecationWarning.
658
Thomas Woutersfb609f42006-02-28 16:37:25 +0000659- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
660 explicitly relative, using 'from .module import name' to mean 'from the same
661 package as this module is in. Imports without dots still default to the
662 old relative-then-absolute, unless 'from __future__ import
663 absolute_import' is used.
664
Brett Cannona7446e32006-02-27 23:39:10 +0000665- Properly check if 'warnings' raises an exception (usually when a filter set
666 to "error" is triggered) when raising a warning for raising string
667 exceptions.
668
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000669- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000670 The name was removed from Include/code.h.
671
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000672- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000673
Guido van Rossum1968ad32006-02-25 22:38:04 +0000674- Patch 1433928:
675 - The copy module now "copies" function objects (as atomic objects).
676 - dict.__getitem__ now looks for a __missing__ hook before raising
677 KeyError.
678
Tim Peters84ef21c2006-02-28 20:39:06 +0000679- PEP 343: with statement implemented. Needs ``from __future__ import
680 with_statement``. Use of 'with' as a variable will generate a warning.
681 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000682 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000683 The following objects have __context__ methods:
684 - The built-in file type.
685 - The thread.LockType type.
686 - The following types defined by the threading module:
687 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
688 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000689
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000690- Fix the encodings package codec search function to only search
691 inside its own package. Fixes problem reported in patch #1433198.
692
693 Note: Codec packages should implement and register their own
694 codec search function. PEP 100 has the details.
695
Tim Peters9ea89d22006-06-04 03:26:02 +0000696- PEP 353: Using ``Py_ssize_t`` as the index type.
697
698- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
699 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
700 now allow Python to make use of memory blocks exceeding 2**32 bytes for
701 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
702 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000703
Neal Norwitzfc76d632006-01-10 06:03:13 +0000704- Patch #1400181, fix unicode string formatting to not use the locale.
705 This is how string objects work. u'%f' could use , instead of .
706 for the decimal point. Now both strings and unicode always use periods.
707
Neal Norwitz671b9e32006-01-09 07:07:12 +0000708- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
709 configure would break checking curses.h.
710
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000711- Bug #959576: The pwd module is now builtin. This allows Python to be
712 built on UNIX platforms without $HOME set.
713
Neal Norwitzc10978f2005-12-19 06:07:16 +0000714- Bug #1072182, fix some potential problems if characters are signed.
715
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000716- Bug #889500, fix line number on SyntaxWarning for global declarations.
717
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000718- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
719
Neal Norwitze7214a12005-12-18 05:03:17 +0000720- Support for converting hex strings to floats no longer works.
721 This was not portable. float('0x3') now raises a ValueError.
722
Barry Warsaw2a38a862005-12-18 01:27:35 +0000723- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000724 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000725 is now displayed in interactive prompt banner.
726
Georg Brandlfa166682005-12-17 21:45:17 +0000727- Implementation of PEP 341 - Unification of try/except and try/finally.
728 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000729 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000730
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000731- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
732 now encodes backslash correctly.
733
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000734- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
735
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000736- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000737 and long longs.
738
Neal Norwitz67715f02005-11-09 06:59:35 +0000739- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000740 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000741 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000742
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000743- Replaced most Unicode charmap codecs with new ones using the
744 new Unicode translate string feature in the builtin charmap
745 codec; the codecs were created from the mapping tables available
746 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
747 encodings now include a mapping for the Apple logo)
748
Tim Peterse3547fd2005-12-16 23:13:57 +0000749- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000750
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000751- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000752
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000753- A new AST parser implementation was completed. The abstract
754 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000755 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000756
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000757- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000758 The following code now raises a SyntaxError: foo(a = i for i in range(10))
759
Neal Norwitz708e51a2005-10-03 04:48:15 +0000760- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
761
Neal Norwitz11bd1192005-10-03 00:54:56 +0000762- SF Bug #887946: fix segfault when redirecting stdin from a directory.
763 Provide a warning when a directory is passed on the command line.
764
Neal Norwitz40d37812005-10-02 01:48:49 +0000765- Fix segfault with invalid coding.
766
767- SF bug #772896: unknown encoding results in MemoryError.
768
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000769- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000770 supported a __len__() method which evaluated to False when the iterator
771 was empty.
772
Guido van Rossum630db602005-09-20 18:49:54 +0000773- On 64-bit platforms, when __len__() returns a value that cannot be
774 represented as a C int, raise OverflowError.
775
Skip Montanarof8948ca2005-09-19 03:54:46 +0000776- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000777 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000778
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000779- SF bug #893549: parsing keyword arguments was broken with a few format
780 codes.
781
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000782- Changes donated by Elemental Security to make it work on AIX 5.3
783 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
784 bug #105470: test_pwd fails on 64bit system (Opteron).
785
Guido van Rossum539c6622005-09-14 17:49:54 +0000786- Changes donated by Elemental Security to make it work on HP-UX 11 on
787 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
788
Georg Brandl4550b8d2005-08-26 06:43:52 +0000789- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000790 (fixes bug #1119418).
791
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000792- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
793
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000794- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
795 exceptions that cause a function to exit.
796
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000797- The implementation of set() and frozenset() was revised to use its
798 own internal data structure. Memory consumption is reduced by 1/3
799 and there are modest speed-ups as well. The API is unchanged.
800
Tim Petersde7990b2005-07-17 23:45:23 +0000801- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
802
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000803- SF bug #1229429: PyObject_CallMethod failed to decrement some
804 reference counts in some error exit cases.
805
Tim Petersecc6e6a2005-07-10 22:30:55 +0000806- SF bug #1185883: Python's small-object memory allocator took over
807 a block managed by the platform C library whenever a realloc specified
808 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000809 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000810 portable way to copy data from the C-managed block into Python's
811 small-object space without risking a memory fault. Python's small-object
812 realloc now leaves such blocks under the control of the platform C
813 realloc.
814
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000815- SF bug #1232517: An overflow error was not detected properly when
816 attempting to convert a large float to an int in os.utime().
817
Raymond Hettinger3296e692005-06-29 23:29:56 +0000818- SF bug #1224347: hex longs now print with lowercase letters just
819 like their int counterparts.
820
Michael W. Hudson188d4362005-06-20 16:52:57 +0000821- SF bug #1163563: the original fix for bug #1010677 ("thread Module
822 Breaks PyGILState_Ensure()") broke badly in the case of multiple
823 interpreter states; back out that fix and do a better job (see
824 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
825 for a longer write-up of the problem).
826
Michael W. Hudsondf888462005-06-03 14:41:55 +0000827- SF patch #1180995: marshal now uses a binary format by default when
828 serializing floats.
829
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000830- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
831 the routines that promise to produce IEEE 754 binary representations
832 of floats now simply copy bytes around.
833
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000834- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
835 278.
836
Brett Cannonc3647ac2005-04-26 03:45:26 +0000837- patch #1109424: int, long, float, complex, and unicode now check for the
838 proper magic slot for type conversions when subclassed. Previously the
839 magic slot was ignored during conversion. Semantics now match the way
840 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000841 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000842 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000843 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000844
Barry Warsawc8d907c2005-04-19 23:43:40 +0000845- Descriptors defined in C with a PyGetSetDef structure, where the setter is
846 NULL, now raise an AttributeError when attempting to set or delete the
847 attribute. Previously a TypeError was raised, but this was inconsistent
848 with the equivalent pure-Python implementation.
849
Michael W. Hudson774479c2005-04-18 08:46:17 +0000850- It is now safe to call PyGILState_Release() before
851 PyEval_InitThreads() (note that if there is reason to believe there
852 are multiple threads around you still must call PyEval_InitThreads()
853 before using the Python API; this fix is for extension modules that
854 have no way of knowing if Python is multi-threaded yet).
855
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000856- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
857 disabled caused a crash.
858
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000859- Bug #1165306: instancemethod_new allowed the creation of a method
860 with im_class == im_self == NULL, which caused a crash when called.
861
Tim Petersecc6e6a2005-07-10 22:30:55 +0000862- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000863 fixes the crash seen in bug #1165761
864
Raymond Hettinger96229b12005-03-11 06:49:40 +0000865- Added two new builtins, any() and all().
866
Brett Cannon409d8f22005-03-05 06:47:57 +0000867- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000868 (e.g., ``class C(): pass`` is no longer a syntax error).
869 Patch #1176012 added support to the 'parser' module and 'compiler' package
870 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000871
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000872- Patch #1115086: Support PY_LONGLONG in structmember.
873
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000874- Bug #1155938: new style classes did not check that __init__() was
875 returning None.
876
Tim Petersecc6e6a2005-07-10 22:30:55 +0000877- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000878 ('\') with a specific error message.
879
Martin v. Löwisff232d72005-03-03 09:24:38 +0000880- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
881
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000882- Bug #1124295: the __name__ attribute of file objects was
883 inadvertently made inaccessible in restricted mode.
884
Tim Petersecc6e6a2005-07-10 22:30:55 +0000885- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000886 an ferror() call.
887
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000888- min() and max() now support key= arguments with the same meaning as in
889 list.sort().
890
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000891- The peephole optimizer now performs simple constant folding in expressions:
892 (2+3) --> (5).
893
Raymond Hettingera422c342005-01-11 03:03:27 +0000894- set and frozenset objects can now be marshalled. SF #1098985.
895
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000896- Bug #1077106: Poor argument checking could cause memory corruption
897 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000898
Jeremy Hyltonab630502005-02-04 18:44:06 +0000899- The parser did not complain about future statements in illegal
900 positions. It once again reports a syntax error if a future
901 statement occurs after anything other than a doc string.
902
Neil Schemenauercf52c072005-08-12 17:34:58 +0000903- Change the %s format specifier for str objects so that it returns a
904 unicode instance if the argument is not an instance of basestring and
905 calling __str__ on the argument returns a unicode instance.
906
Tim Petersf4e69282006-02-27 17:15:31 +0000907- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
908 current thread state when the auto-GIL-state machinery knows about
909 it (since the thread state is being deleted, continuing to remember it
910 can't help, but can hurt if another thread happens to get created with
911 the same thread id).

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001043- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1044 the request code argument, which results in more C-like behaviour
1045 for large or negative values.

1092 islice(s.start, s.stop, s.step)
1093
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001094- datetime.datetime() now has a strptime class method which can be used to

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001100Library
1101-------
1102
Nick Coghlan43832302006-04-23 17:04:07 +00001103- PEP 338: new module runpy defines a run_module function to support
1104 executing modules which provide access to source code or a code object
1105 via the PEP 302 import mechanisms.
1106
Anthony Baxter93f5b932006-04-03 08:05:07 +00001107- The email module's parsedate_tz function now sets the daylight savings
1108 flag to -1 (unknown) since it can't tell from the date whether it should
1109 be set.
1110
Fred Drakead5177c2006-04-01 22:14:43 +00001111- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
1112 now sport attributes that provide access to the parts of the result.
1113

1115 in attribute values.
1116
Anthony Baxterc51ee692006-04-01 00:57:31 +00001117- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001118 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001119 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001120 module will not be built.
1121
Tim Petersc17976e2006-04-01 00:26:53 +00001122- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1123 aren't officially supported here, and trying to use them will probably
1124 raise an exception some day. But dicts have been allowed, and "mostly
1125 worked", so support for them won't go away without warning.
1126
Georg Brandl338ef7d2006-03-31 18:42:16 +00001127- Bug #1445068: getpass.getpass() can now be given an explicit stream
1128 argument to specify where to write the prompt.
1129
Georg Brandl22ec80b2006-03-31 18:25:44 +00001130- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1145
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001146- email 4.0 package now integrated. This is largely the same as the email 3.0
1147 package that was included in Python 2.3, except that PEP 8 module names are
1148 now used (e.g. mail.message instead of email.Message). The MIME classes
1149 have been moved to a subpackage (e.g. email.mime.text instead of
1150 email.MIMEText). The old names are still supported for now. Several
1151 deprecated Message methods have been removed and lots of bugs have been
1152 fixed. More details can be found in the email package documentation.
1153
Walter Dörwald40108c92006-03-27 08:15:44 +00001154- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1155 (a subclass of tuple) that provides incremental decoders and encoders
1156 (a way to use stateful codecs without the stream API). Python functions
1157 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1158 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1159 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001160
Walter Dörwald067db482006-03-15 22:17:27 +00001161- Patch #1359365: Calling next() on a closed StringIO.String object raises
1162 a ValueError instead of a StopIteration now (like file and cString.String do).
1163 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1164 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001165
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001166- A regrtest option -w was added to re-run failed tests in verbose mode.
1167

1169 interpreter to exit.
1170
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001171- The function get_count() has been added to the gc module, and gc.collect()
1172 grew an optional 'generation' argument.

1243 "The consensus of researchers in this area (at least as
1244 expressed at the NIST Hash Function Workshop 10/31/05),
1245 is that SHA-256 is a good choice for the time being, but
1246 that research should continue, and other alternatives may
1247 arise from this research. The larger SHA's also seem OK."

Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001430 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001431 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001432 + Dialect parameter parsing has been re-implemented to improve error
1433 reporting.
1434 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1435 dictates.
1436 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001437 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001438 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001439 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1440 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001441 + reader now allows \r characters to be quoted (previously it only allowed
1442 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001443 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001444 + Dialect classes passed to the module are no longer instantiated by
1445 the module before being parsed (the former validation scheme required
1446 this, but the mechanism was unreliable).
1447 + The dialect registry now contains instances of the internal
1448 C-coded dialect type, rather than references to python objects.
1449 + the internal c-coded dialect type is now immutable.
1450 + register_dialect now accepts the same keyword dialect specifications
1451 as the reader and writer, allowing the user to register dialects
1452 without first creating a dialect class.
1453 + a configurable limit to the size of parsed fields has been added -
1454 previously, an unmatched quote character could result in the entire
1455 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001456 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001457 the parser field size limit (returning the former limit). The initial
1458 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001459 + A line_num attribute has been added to the reader object, which tracks
1460 the number of lines read from the source iterator. This is not
1461 the same as the number of records returned, as records can span
1462 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001463 + reader and writer objects were not being registered with the cyclic-GC.
1464 This has been fixed.
1465
Brett Cannone6539c42005-01-08 02:43:53 +00001466- _DummyThread objects in the threading module now delete self.__block that is
1467 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1468 lock primitives tend to be limited in number and thus should not be wasted on
1469 a _DummyThread object. Fixes bug #1089632.
1470
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001471- The imghdr module now detects Exif files.
1472
Raymond Hettinger6065d322004-12-20 23:51:53 +00001473- StringIO.truncate() now correctly adjusts the size attribute.
1474 (Bug #951915).
1475
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001476- locale.py now uses an updated locale alias table (built using
1477 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1478 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001479 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001480
Raymond Hettinger3557f422004-12-07 12:02:02 +00001481- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1482
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001483- the pickle module no longer accepts the deprecated None option in the
1484 args tuple returned by __reduce__().
1485
Brett Cannon84667c02004-12-07 03:25:18 +00001486- optparse now optionally imports gettext. This allows its use in setup.py.
1487
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001488- the pickle module no longer uses the deprecated bin parameter.
1489
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001490- the shelve module no longer uses the deprecated binary parameter.
1491
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001492- the pstats module no longer uses the deprecated ignore() method.
1493
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001494- the filecmp module no longer uses the deprecated use_statcache argument.
1495
Raymond Hettinger664347b2004-12-04 21:21:53 +00001496- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1497 extended or overridden by subclasses. Formerly, the subclassed method would
1498 be ignored by the rest of the module. (Bug #1078905).
1499
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001500- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001501 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001502
Walter Dörwald36733692004-12-22 12:50:50 +00001503- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1504 once when a size argument is given. This prevents a buffer overflow in the
1505 tokenizer with very long source lines.
1506
Barry Warsaw538561e2006-01-01 21:48:54 +00001507- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1508 immediately after creating the object, without any intervening
1509 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001510
Skip Montanaro05885812005-01-16 20:48:27 +00001511- The reconvert.quote function can now emit triple-quoted strings. The
1512 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001513
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001514- ``UserString.MutableString`` now supports negative indices in
1515 ``__setitem__`` and ``__delitem__``
1516
Greg Ward40407942005-03-05 02:53:17 +00001517- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1518 correctly.
1519
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001520- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1521 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1522 character even if the user has passed a size parameter to get a proper
1523 line ending. Remove the special handling of a "\r\n" that has been split
1524 between two lines.
1525
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001526- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1527 about illegal code points. The codec now supports PEP 293 style error
1528 handlers.
1529
Walter Dörwald78a78b02005-09-01 12:04:29 +00001530- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001531 from the input stream, so that the output is a byte string in the correct
1532 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001533
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001534- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1535 considering it exactly like a '*'.
1536
Walter Dörwald007f8df2005-10-09 19:42:27 +00001537- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1538 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001539
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001540- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1541
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001542- Patch #1413711: Certain patterns of differences were making difflib
1543 touch the recursion limit.
1544
Walter Dörwald58917a62006-03-31 15:26:22 +00001545- Bug #947906: An object oriented interface has been added to the calendar
1546 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001547 called as a script (e.g. via ``python -mcalendar``). Localized month and
1548 weekday names can be ouput (even if an exotic encoding is used) using
1549 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001550

1553
Neal Norwitz602d3392006-03-31 08:21:40 +00001554- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1555 by using -mieee gcc option.
1556

1558
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001559- Build support for Win64-AMD64 was added.
1560
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001561- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1562
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001563- Patch #881820: look for openpty and forkpty also in libbsd.
1564
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001565- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1566 The zlib module is now builtin on Windows.
1567
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001568- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1569
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001570- Bug #1189330: configure did not correctly determine the necessary
1571 value of LINKCC if python was built with GCC 4.0.
1572
Trent Mick8321b422005-07-26 02:29:21 +00001573- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1574 vulnerability in zlib 1.2.1 and 1.2.2.
1575
Brett Cannon08cd5982005-04-24 22:26:38 +00001576- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1577 flags that change binary compatibility. Changes were also made to
1578 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001579 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001580
Bob Ippolitoed233462005-03-29 13:47:59 +00001581- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1582 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1583 no longer exists). This configure patch makes things right.
1584
Martin v. Löwise2713be2005-03-08 15:03:08 +00001585- Bug #1158607: Build with --disable-unicode again.
1586
Brett Cannon46d96232005-02-16 00:07:19 +00001587- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1588 defined. Discovered as a result of not being able to build on OS X.
1589
Brett Cannon516592f2004-12-07 00:42:59 +00001590- setup.py now uses the directories specified in LDFLAGS using the -L option
1591 and in CPPFLAGS using the -I option for adding library and include
1592 directories, respectively, for compiling extension modules against. This has
1593 led to the core being compiled using the values in CPPFLAGS. It also removes
1594 the need for the special-casing of both DarwinPorts and Fink for darwin since
1595 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1596 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1597 Fink, ``-I/opt/local/include`` for DarwinPorts).
1598
Brett Cannon43802422005-02-10 20:48:03 +00001599- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1600 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1601 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1602 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001604C API
1605-----
1606
Tim Petersc9d78aa2006-03-26 23:27:58 +00001607- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1608 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1609 is obtained via the ``PyObject_`` family, it must be released via the
1610 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1611 always been officially true, but when Python's small-object allocator was
1612 introduced, an attempt was made to cater to a few extension modules
1613 discovered at the time that obtained memory via ``PyObject_New`` but
1614 released it via ``PyMem_DEL``. It's years later, and if such code still
1615 exists it will fail now (probably with segfaults, but calling wrong
1616 low-level memory management functions can yield many symptoms).
1617
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001618- Added a C API for set and frozenset objects.
1619

1621
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001622- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1623 mapping argument now. This string is used as a mapping table. Byte values
1624 greater than the length of the string and 0xFFFE are treated as undefined
1625 mappings.
