12Core and builtins
13-----------------
14
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000015- Bug #1441486: The literal representation of -(sys.maxint - 1)
16 again evaluates to a int object, not a long.
17
Neil Schemenauer0e07b602006-07-09 16:16:34 +000018- Bug #1501934: The scope of global variables that are locally assigned
19 using augmented assignment is now correctly determined.
20
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000021- Bug #927248: Recursive method-wrapper objects can now safely

23
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000024- Bug #1417699: Reject locale-specific decimal point in float()
25 and atof().
26
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000027- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
28 omit a default "error" argument for NULL pointer. This allows
29 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000030
Neal Norwitzfb48afa2006-07-08 05:31:37 +000031- Bug #1519018: 'as' is now validated properly in import statements.
32
Neal Norwitz28746ab2006-07-09 22:14:42 +000033- On 64 bit systems, int literals that use less than 64 bits are
34 now ints rather than longs.
35
Neal Norwitzed657552006-07-10 00:04:44 +000036- Bug #1512814, Fix incorrect lineno's when code at module scope

40-------
41
Martin v. Löwis8d656812006-07-10 07:23:48 +000042- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
43 environment variable to be set in order to the SDK environment
44 for finding the compiler, include files, etc.
45
Martin v. Löwis388a8c22006-07-06 19:28:03 +000046- Bug #1515998: Properly generate logical ids for files in bdist_msi.

49
Thomas Woutersadd19112006-07-05 11:03:49 +000050- string.Template() now correctly handles tuple-values. Previously,
51 multi-value tuples would raise an exception and single-value tuples would
52 be treated as the value they contain, instead.
53
Martin v. Löwisede77f52006-07-03 13:01:35 +000054- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

61 degrees and radians.
62
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000063- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +000064 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000065
Martin v. Löwisbd39c032006-07-03 09:44:00 +000066- Bug #1514703: Only setup canvas window in turtle when the canvas
67 is created.
68
Martin v. Löwis7596e832006-07-01 15:33:37 +000069- Bug #1513223: .close() of a _socketobj now releases the underlying

79
Brett Cannon53ab5b72006-06-22 16:49:14 +000080- Bug #1510580: The 'warnings' module improperly required that a Warning
81 category be either a types.ClassType and a subclass of Warning. The proper
82 check is just that it is a subclass with Warning as the documentation states.
83
Georg Brandlad29e632006-06-21 17:45:17 +000084- The compiler module now correctly compiles the new try-except-finally
85 statement (bug #1509132).
86
Neal Norwitz60373cd2006-06-22 06:30:50 +000087- The wsgiref package is now installed properly on Unix.
88
Vinay Sajip28e57612006-07-01 10:45:20 +000089- A bug was fixed in logging.config.fileConfig() which caused a crash on
90 shutdown when fileConfig() was called multiple times.
91
Gerhard Häring762fbd32006-07-02 17:48:30 +000092- The sqlite3 module did cut off data from the SQLite database at the first
93 null character before sending it to a custom converter. This has been fixed
94 now.
95
Neal Norwitz0f8b31a2006-06-28 06:28:31 +000096Extension Modules
97-----------------
98
Thomas Hellerb9cb84f2006-07-10 11:17:37 +000099- Assigning None to pointer type fields in ctypes structures possible
100 overwrote the wrong fields, this is fixed now.
101
102- Fixed a segfault in _ctypes when ctypes.wintypes were imported
103 on non-Windows platforms.
104
105- Bug #1518190: The ctypes.c_void_p constructor now accepts any
106 integer or long, without range checking.
107
108- Patch #1517790: It is now possible to use custom objects in the ctypes
109 foreign function argtypes sequence as long as they provide a from_param
110 method, no longer is it required that the object is a ctypes type.
111
112- The '_ctypes' extension module now works when Python is configured
113 with the --without-threads option.
114
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000115- Bug #1513646: os.access on Windows now correctly determines write

119 a KeyboardInterrupt.
120
Neal Norwitza12aa882006-07-06 06:45:08 +0000121- Bug #1296433: parsing XML with a non-default encoding and
122 a CharacterDataHandler could crash the interpreter in pyexpat.
123
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000124- Patch #1516912: improve Modules support for OpenVMS.

127-----
128
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000129- 'configure' now detects the zlib library the same way as distutils.
130 Previously, the slight difference could cause compilation errors of the
131 'zlib' module on systems with more than one version of zlib.
132
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000133- The MSI compileall step was fixed to also support a TARGETDIR
134 with spaces in it.
135
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000136- Bug #1517388: sqlite3.dll is now installed on Windows independent
137 of Tcl/Tk.
138

149-------------
150
Nick Coghlan2d792252006-07-06 13:47:18 +0000151- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
152 documentation for the warnings module.
153
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000154- Patch #1509163: MS Toolkit Compiler no longer available.
155

Nick Coghlanc649ec52006-05-29 12:43:05 +0000158What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000159================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000160
Anthony Baxterd1136802006-06-19 12:04:15 +0000161*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000162
163Core and builtins
164-----------------
165
Georg Brandla56b9152006-06-19 06:35:54 +0000166- Patch #1507676: Error messages returned by invalid abstract object operations
167 (such as iterating over an integer) have been improved and now include the
168 type of the offending object to help with debugging.
169
Brett Cannonea3912b2006-06-13 21:46:41 +0000170- Bug #992017: A classic class that defined a __coerce__() method that returned
171 its arguments swapped would infinitely recurse and segfault the interpreter.
172
Neal Norwitz909eb122006-06-12 02:13:21 +0000173- Fix the socket tests so they can be run concurrently.
174
Neal Norwitzb9845e72006-06-12 02:11:18 +0000175- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000176 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000177
Brett Cannon22565aa2006-06-09 22:31:23 +0000178- Bug #532646: object.__call__() will continue looking for the __call__
179 attribute on objects until one without one is found. This leads to recursion
180 when you take a class and set its __call__ attribute to an instance of the
181 class. Originally fixed for classic classes, but this fix is for new-style.
182 Removes the infinite_rec_3 crasher.
183
Georg Brandl24250812006-06-09 18:45:48 +0000184- The string and unicode methods startswith() and endswith() now accept
185 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
186
Brett Cannonde3b0522006-06-08 17:00:45 +0000187- Buffer objects, at the C level, never used the char buffer
188 implementation even when the char buffer for the wrapped object was
189 explicitly requested (originally returned the read or write buffer).
190 Now a TypeError is raised if the char buffer is not present but is
191 requested.
192
Georg Brandlddbaa662006-06-04 21:56:52 +0000193- Patch #1346214: Statements like "if 0: suite" are now again optimized
194 away like they were in Python 2.4.
195
Georg Brandlb7c8f542006-05-27 12:30:25 +0000196- Builtin exceptions are now full-blown new-style classes instead of
197 instances pretending to be classes, which speeds up exception handling
198 by about 80% in comparison to 2.5a2.
199
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000200- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
201 Unicode 4.1.
202
Georg Brandlf4ef1162006-05-26 18:03:31 +0000203- Patch #921466: sys.path_importer_cache is now used to cache valid and
204 invalid file paths for the built-in import machinery which leads to
205 fewer open calls on startup.
206
Tim Peters696cf432006-05-24 21:10:40 +0000207- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
208 of-2 bases. The largest speedup is for inputs with about 1000 decimal
209 digits. Conversion from non-power-of-2 bases remains quadratic-time in
210 the number of input digits (it was and remains linear-time for bases
211 2, 4, 8, 16 and 32).
212
Tim Petersb713ec22006-05-23 18:45:30 +0000213- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
214 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
215 an integer close to ``sys.maxint``. This was repaired by patch
216 #1335972, which also gives a nice speedup.
217
Richard Jonescebbefc2006-05-23 18:28:17 +0000218- Patch #1337051: reduced size of frame objects.
219
220- PyErr_NewException now accepts a tuple of base classes as its
221 "base" parameter.
222
Richard Jones7c88dcc2006-05-23 10:37:38 +0000223- Patch #876206: function call speedup by retaining allocated frame
224 objects.
225
Georg Brandl7b90e162006-05-18 07:01:27 +0000226- Bug #1462152: file() now checks more thoroughly for invalid mode
227 strings and removes a possible "U" before passing the mode to the
228 C library function.
229
Neal Norwitz1004a532006-05-15 07:17:23 +0000230- Patch #1488312, Fix memory alignment problem on SPARC in unicode
231
Neal Norwitz373f0a72006-05-15 07:04:36 +0000232- Bug #1487966: Fix SystemError with conditional expression in assignment
233
Martin v. Löwis879768d2006-05-11 13:28:43 +0000234- WindowsError now has two error code attributes: errno, which carries
235 the error values from errno.h, and winerror, which carries the error
236 values from winerror.h. Previous versions put the winerror.h values
237 (from GetLastError()) into the errno attribute.
238
Martin v. Löwis77736712006-05-04 05:51:03 +0000239- Patch #1475845: Raise IndentationError for unexpected indent.
240
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000241- Patch #1479181: split open() and file() from being aliases for each other.
242
Tim Peters44bd9862006-06-01 13:49:23 +0000243- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
244 methods were always silently ignored by dictionaries when comparing keys.
245 They are now passed through (except when using the C API function
246 ``PyDict_GetItem()``, whose semantics did not change).
247
248- Bug #1456209: In some obscure cases it was possible for a class with a
249 custom ``__eq__()`` method to confuse dict internals when class instances
250 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
251 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000253Extension Modules
254-----------------
255
Trent Mick960a3f82006-06-28 20:30:41 +0000256- Bug #1295808: expat symbols should be namespaced in pyexpat
257
258- Patch #1462338: Upgrade pyexpat to expat 2.0.0
259
Brett Cannon6ee7d012006-06-08 16:23:04 +0000260- Change binascii.hexlify to accept a read-only buffer instead of only a char
261 buffer and actually follow its documentation.
262
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000263- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
264
Nick Coghlanc649ec52006-05-29 12:43:05 +0000265- Patch #1478788 (modified version): The functional extension module has
266 been renamed to _functools and a functools Python wrapper module added.
267 This provides a home for additional function related utilities that are
268 not specifically about functional programming. See PEP 309.
269
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000270- Patch #1493701: performance enhancements for struct module.
271

278 enabled builds on Windows and systems with Posix threads support.
279
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000280- On Win32, os.listdir now supports arbitrarily-long Unicode path names
281 (up to the system limit of 32K characters).
282
283- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
284 As a result, these functions now raise WindowsError instead of OSError.
285
Tim Peters7a822da2006-05-25 21:50:17 +0000286- ``time.clock()`` on Win64 should use the high-performance Windows
287 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
288 Windows platforms).
289
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000290- Calling Tk_Init twice is refused if the first call failed as that
291 may deadlock.
292
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000293- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
294 accept it without potentially using an uninitialized pointer.
295
296- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
297 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
298 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000299
Gregory P. Smith372b5832006-06-05 18:48:21 +0000300- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000301 [pybsddb project SF patch number 1466734]
302
Gregory P. Smith372b5832006-06-05 18:48:21 +0000303- bsddb: fix DBCursor.pget() bug with keyword argument names when no data

305
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000306- bsddb: the __len__ method of a DB object has been fixed to return correct
307 results. It could previously incorrectly return 0 in some cases.
308 Fixes SF bug 1493322 (pybsddb bug 1184012).
309
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000310- bsddb: the bsddb.dbtables Modify method now raises the proper error and
311 aborts the db transaction safely when a modifier callback fails.

Gregory P. Smith506f7b52006-06-15 08:52:32 +0000314- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000315 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000316 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
317 database calls that would previously deadlock. [SF python bug #775414]

Georg Brandl83cc0d02006-06-14 08:50:03 +0000340- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
341 mime.types file for determining MIME types.
342
Georg Brandl2605ca82006-06-14 06:08:31 +0000343- Bug #1339007: Shelf objects now don't raise an exception in their
344 __del__ method when initialization failed.
345
Martin v. Löwisd8251432006-06-14 05:21:04 +0000346- Patch #1455898: The MBCS codec now supports the incremental mode for
347 double-byte encodings.
348
Tim Peters43898b42006-06-14 04:09:25 +0000349- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
350 guarantee that adjacent triples in the return list always describe
351 non-adjacent blocks. Previously, a pair of matching blocks could end
352 up being described by multiple adjacent triples that formed a partition
353 of the matching pair.
354
Greg Ward0e0c9f42006-06-11 16:24:11 +0000355- Bug #1498146: fix optparse to handle Unicode strings in option help,
356 description, and epilog.
357
Greg Wardd1c797e2006-06-11 14:42:41 +0000358- Bug #1366250: minor optparse documentation error.
359
Greg Ward7f547402006-06-11 00:40:49 +0000360- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
361 clarify docs.
362
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000363- The wsgiref package has been added to the standard library.
364
Nick Coghlan676725d2006-06-08 13:54:49 +0000365- The functions update_wrapper() and wraps() have been added to the functools
366 module. These make it easier to copy relevant metadata from the original
367 function when writing wrapper functions.
368
Tim Petersd6a9eef2006-06-05 01:48:21 +0000369- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
370 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000371
Martin v. Löwis3f767792006-06-04 19:36:28 +0000372- Patch #1359618: Speed up charmap encoder by using a trie structure
373 for lookup.
374
Tim Petersd609b1a2006-06-02 23:22:51 +0000375- The functions in the ``pprint`` module now sort dictionaries by key
376 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
377 if and only if its display required more than one line, although that
378 wasn't documented. The new behavior increases predictability; e.g.,
379 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
380
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000381- Patch #1497027: try HTTP digest auth before basic auth in urllib2

390
Georg Brandlb89316f2006-05-17 15:51:16 +0000391- Patch #1180296: Two new functions were added to the locale module:
392 format_string() to get the effect of "format % items" but locale-aware,
393 and currency() to format a monetary number with currency sign.
394
Georg Brandle3a25832006-05-17 14:56:04 +0000395- Patch #1486962: Several bugs in the turtle Tk demo module were fixed

399 tarfiles.
400
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000401- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
402 stdout arguments, making it possible to redirect input and output
403 for remote debugging.
404
405- Patch #1484695: Update the tarfile module to version 0.8. This fixes
406 a couple of issues, notably handling of long file names using the
407 GNU LONGNAME extension.
408

410 new flag when ``name`` is already the name of an option flag.
411
412- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
413 package.
414
415- Patch #1472854: make the rlcompleter.Completer class usable on non-
416 UNIX platforms.
417
418- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000451What's New in Python 2.5 alpha 2?
452=================================
453
454*Release date: 27-APR-2006*
455
456Core and builtins
457-----------------
458
Thomas Heller1b046642006-04-18 18:51:06 +0000459- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
460 by converting these apis from macros into exported functions again:
461
462 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
463 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
464 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
465 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
466 PyRun_String Py_CompileString
467
Martin v. Löwis45294a92006-04-18 06:24:08 +0000468- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
469
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000470- All uses of PyStructSequence_InitType have been changed to initialize
471 the type objects only once, even if the interpreter is initialized
472 multiple times.
473
Neal Norwitz61546162006-04-14 05:20:28 +0000474- Bug #1454485, array.array('u') could crash the interpreter. This was
475 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
476 to unicode when it didn't make sense. 'u#' now requires a unicode string.
477
478- Py_UNICODE is unsigned. It was always documented as unsigned, but
479 due to a bug had a signed value in previous versions.
480
Tim Peters3a5e8b12006-04-11 01:44:07 +0000481- Patch #837242: ``id()`` of any Python object always gives a positive
482 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
483 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000484 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000485 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000486
Tim Peters3a5e8b12006-04-11 01:44:07 +0000487 def __hash__(self):
488 return id(self) # WRONG
489
490 because a hash result must be a (short) Python int but it was always
491 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000492 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000493 was always usable as a hash value before this patch. That's no longer
494 necessarily so.
495
496- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000497 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000498 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000499 #1454844)
500
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000501- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
502 involving generators that have paused outside of any ``try`` or ``with``
503 blocks. (In 2.5a1, a paused generator that was part of a reference
504 cycle could not be garbage collected, regardless of whether it was
505 paused in a ``try`` or ``with`` block.)

522 a temporary db (file=None) with the 'n' flag to truncate on open.
523
524- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
525 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000526
Armin Rigoa9017c32006-04-19 11:50:27 +0000527- Patch #1062014: AF_UNIX sockets under Linux have a special

532
Tim Peters711bf302006-04-25 03:31:36 +0000533- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
534 a doctest to be skipped (the code is not run, and the expected output
535 or exception is ignored).
536
Nick Coghlanda2268f2006-04-24 04:37:15 +0000537- Fixed contextlib.nested to cope with exceptions being raised and
538 caught inside exit handlers.
539
Greg Wardab05edc2006-04-23 03:47:58 +0000540- Updated optparse module to Optik 1.5.1 (allow numeric constants in
541 hex, octal, or binary; add ``append_const`` action; keep going if
542 gettext cannot be imported; added ``OptionParser.destroy()`` method;
543 added ``epilog`` for better help generation).
544
Tim Peters21fbd572006-04-21 21:18:10 +0000545- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
546 called from a thread spawned as a side effect of importing a module.
547
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000548- The pydoc module now supports documenting packages contained in
549 .zip or .egg files.
550
551- The pkgutil module now has several new utility functions, such
552 as ``walk_packages()`` to support working with packages that are either
553 in the filesystem or zip files.
554
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000555- The mailbox module can now modify and delete messages from
556 mailboxes, in addition to simply reading them. Thanks to Gregory
557 K. Johnson for writing the code, and to the 2005 Google Summer of
558 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000559
Tim Petersc7605f22006-04-17 21:12:33 +0000560- The ``__del__`` method of class ``local`` in module ``_threading_local``
561 returned before accomplishing any of its intended cleanup.
562
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000563- Patch #790710: Add breakpoint command lists in pdb.
564
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000565- Patch #1063914: Add Tkinter.Misc.clipboard_get().

568
Anthony Baxtere29002c2006-04-12 12:07:31 +0000569- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
570 Windows. Bug #1469163.
571
Phillip J. Eby47032112006-04-11 01:07:43 +0000572- The warnings, linecache, inspect, traceback, site, and doctest modules
573 were updated to work correctly with modules imported from zipfiles or
574 via other PEP 302 __loader__ objects.
575

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000596- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
597 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000598 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000599 CXX from --with-cxx-main, see description in README.
600

604
Tim Peters8931ff12006-05-13 23:28:20 +0000605- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
606 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

611
Nick Coghlanda2268f2006-04-24 04:37:15 +0000612- test_contextlib now checks contextlib.nested can cope with exceptions
613 being raised and caught inside exit handlers.
614
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000615- test_cmd_line now checks operation of the -m and -c command switches
616
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000617- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
618 it separately and by hand. It also wasn't cleaning up its changes to
619 the current Decimal context.
620
Thomas Woutersabd08882006-04-26 15:53:30 +0000621- regrtest.py now has a -M option to run tests that test the new limits of
622 containers, on 64-bit architectures. Running these tests is only sensible
623 on 64-bit machines with more than two gigabytes of memory. The argument
624 passed is the maximum amount of memory for the tests to use.

633-------------
634
Tim Petersb06d28c2006-05-12 01:57:59 +0000635- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
636
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000637- PEP 343: Added Context Types section to the library reference
638 and attempted to bring other PEP 343 related documentation into
639 line with the implementation and/or python-dev discussions.
640
Tim Peters8dc73d22006-04-24 02:03:16 +0000641- Bug #1337990: clarified that ``doctest`` does not support examples
642 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000645What's New in Python 2.5 alpha 1?
646=================================
647
Anthony Baxterebed3f62006-04-03 15:03:44 +0000648*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000649
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000650Core and builtins
651-----------------
652
Nick Coghlan43832302006-04-23 17:04:07 +0000653- PEP 338: -m command line switch now delegates to runpy.run_module
654 allowing it to support modules in packages and zipfiles
655
Martin v. Löwisc661b882006-04-20 04:54:23 +0000656- On Windows, .DLL is not an accepted file name extension for
657 extension modules anymore; extensions are only found if they
658 end in .PYD.
659
Martin v. Löwisea62d252006-04-03 10:56:49 +0000660- Bug #1421664: sys.stderr.encoding is now set to the same value as
661 sys.stdout.encoding.
662
Neal Norwitz92e212f2006-04-03 04:48:37 +0000663- __import__ accepts keyword arguments.
664
Georg Brandlccadf842006-03-31 18:54:53 +0000665- Patch #1460496: round() now accepts keyword arguments.
666
Anthony Baxter262c00a2006-03-30 10:53:17 +0000667- Fixed bug #1459029 - unicode reprs were double-escaped.
668
Hye-Shik Changd478f342006-03-23 12:32:36 +0000669- Patch #1396919: The system scope threads are reenabled on FreeBSD
670 5.4 and later versions.
671
Neal Norwitze98ccf62006-03-23 05:39:47 +0000672- Bug #1115379: Compiling a Unicode string with an encoding declaration
673 now gives a SyntaxError.
674
Georg Brandlabd1ff82006-03-18 07:59:59 +0000675- Previously, Python code had no easy way to access the contents of a
676 cell object. Now, a ``cell_contents`` attribute has been added
677 (closes patch #1170323).
678
Tim Peterscf79aac2006-03-16 01:14:46 +0000679- Patch #1123430: Python's small-object allocator now returns an arena to
680 the system ``free()`` when all memory within an arena becomes unused
681 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
682 freed. Some applications will see a drop in virtual memory size now,
683 especially long-running applications that, from time to time, temporarily
684 use a large number of small objects. Note that when Python returns an
685 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000686 platform C library will in turn return that memory to the operating system.
687 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000688 appears to be effective at least on Microsoft C and gcc-based systems.
689 Thanks to Evan Jones for hard work and patience.
690
Georg Brandl533ff6f2006-03-08 18:09:27 +0000691- Patch #1434038: property() now uses the getter's docstring if there is
692 no "doc" argument given. This makes it possible to legitimately use
693 property() as a decorator to produce a read-only property.
694
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000695- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
696 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
697 of requiring an int or long in slicing and a few other contexts, enabling
698 other objects (e.g. Numeric Python's integers) to be used as slice indices.
699
Neal Norwitz995acdf2006-03-07 05:01:00 +0000700- Fixed various bugs reported by Coverity's Prevent tool.
701
Brett Cannonbf364092006-03-01 04:25:17 +0000702- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
703 new exception base class, BaseException, which has a new message attribute.
704 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
705 Raising a string exception now raises a DeprecationWarning.
706
Thomas Woutersfb609f42006-02-28 16:37:25 +0000707- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
708 explicitly relative, using 'from .module import name' to mean 'from the same
709 package as this module is in. Imports without dots still default to the
710 old relative-then-absolute, unless 'from __future__ import
711 absolute_import' is used.
712
Brett Cannona7446e32006-02-27 23:39:10 +0000713- Properly check if 'warnings' raises an exception (usually when a filter set
714 to "error" is triggered) when raising a warning for raising string
715 exceptions.
716
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000717- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000718 The name was removed from Include/code.h.
719
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000720- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000721
Guido van Rossum1968ad32006-02-25 22:38:04 +0000722- Patch 1433928:
723 - The copy module now "copies" function objects (as atomic objects).
724 - dict.__getitem__ now looks for a __missing__ hook before raising
725 KeyError.
726
Tim Peters84ef21c2006-02-28 20:39:06 +0000727- PEP 343: with statement implemented. Needs ``from __future__ import
728 with_statement``. Use of 'with' as a variable will generate a warning.
729 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000730 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000731 The following objects have __context__ methods:
732 - The built-in file type.
733 - The thread.LockType type.
734 - The following types defined by the threading module:
735 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
736 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000737
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000738- Fix the encodings package codec search function to only search
739 inside its own package. Fixes problem reported in patch #1433198.
740
741 Note: Codec packages should implement and register their own
742 codec search function. PEP 100 has the details.
743
Tim Peters9ea89d22006-06-04 03:26:02 +0000744- PEP 353: Using ``Py_ssize_t`` as the index type.
745
746- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
747 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
748 now allow Python to make use of memory blocks exceeding 2**32 bytes for
749 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
750 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000751
Neal Norwitzfc76d632006-01-10 06:03:13 +0000752- Patch #1400181, fix unicode string formatting to not use the locale.
753 This is how string objects work. u'%f' could use , instead of .
754 for the decimal point. Now both strings and unicode always use periods.
755
Neal Norwitz671b9e32006-01-09 07:07:12 +0000756- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
757 configure would break checking curses.h.
758
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000759- Bug #959576: The pwd module is now builtin. This allows Python to be
760 built on UNIX platforms without $HOME set.
761
Neal Norwitzc10978f2005-12-19 06:07:16 +0000762- Bug #1072182, fix some potential problems if characters are signed.
763
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000764- Bug #889500, fix line number on SyntaxWarning for global declarations.
765
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000766- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
767
Neal Norwitze7214a12005-12-18 05:03:17 +0000768- Support for converting hex strings to floats no longer works.
769 This was not portable. float('0x3') now raises a ValueError.
770
Barry Warsaw2a38a862005-12-18 01:27:35 +0000771- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000772 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000773 is now displayed in interactive prompt banner.
774
Georg Brandlfa166682005-12-17 21:45:17 +0000775- Implementation of PEP 341 - Unification of try/except and try/finally.
776 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000777 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000778
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000779- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
780 now encodes backslash correctly.
781
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000782- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
783
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000784- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000785 and long longs.
786
Neal Norwitz67715f02005-11-09 06:59:35 +0000787- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000788 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000789 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000790
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000791- Replaced most Unicode charmap codecs with new ones using the
792 new Unicode translate string feature in the builtin charmap
793 codec; the codecs were created from the mapping tables available
794 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
795 encodings now include a mapping for the Apple logo)
796
Tim Peterse3547fd2005-12-16 23:13:57 +0000797- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000798
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000799- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000800
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000801- A new AST parser implementation was completed. The abstract
802 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000803 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000804
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000805- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000806 The following code now raises a SyntaxError: foo(a = i for i in range(10))
807
Neal Norwitz708e51a2005-10-03 04:48:15 +0000808- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
809
Neal Norwitz11bd1192005-10-03 00:54:56 +0000810- SF Bug #887946: fix segfault when redirecting stdin from a directory.
811 Provide a warning when a directory is passed on the command line.
812
Neal Norwitz40d37812005-10-02 01:48:49 +0000813- Fix segfault with invalid coding.
814
815- SF bug #772896: unknown encoding results in MemoryError.
816
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000817- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000818 supported a __len__() method which evaluated to False when the iterator
819 was empty.
820
Guido van Rossum630db602005-09-20 18:49:54 +0000821- On 64-bit platforms, when __len__() returns a value that cannot be
822 represented as a C int, raise OverflowError.
823
Skip Montanarof8948ca2005-09-19 03:54:46 +0000824- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000825 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000826
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000827- SF bug #893549: parsing keyword arguments was broken with a few format
828 codes.
829
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000830- Changes donated by Elemental Security to make it work on AIX 5.3
831 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
832 bug #105470: test_pwd fails on 64bit system (Opteron).
833
Guido van Rossum539c6622005-09-14 17:49:54 +0000834- Changes donated by Elemental Security to make it work on HP-UX 11 on
835 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
836
Georg Brandl4550b8d2005-08-26 06:43:52 +0000837- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000838 (fixes bug #1119418).
839
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000840- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
841
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000842- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
843 exceptions that cause a function to exit.
844
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000845- The implementation of set() and frozenset() was revised to use its
846 own internal data structure. Memory consumption is reduced by 1/3
847 and there are modest speed-ups as well. The API is unchanged.
848
Tim Petersde7990b2005-07-17 23:45:23 +0000849- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
850
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000851- SF bug #1229429: PyObject_CallMethod failed to decrement some
852 reference counts in some error exit cases.
853
Tim Petersecc6e6a2005-07-10 22:30:55 +0000854- SF bug #1185883: Python's small-object memory allocator took over
855 a block managed by the platform C library whenever a realloc specified
856 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000857 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000858 portable way to copy data from the C-managed block into Python's
859 small-object space without risking a memory fault. Python's small-object
860 realloc now leaves such blocks under the control of the platform C
861 realloc.
862
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000863- SF bug #1232517: An overflow error was not detected properly when
864 attempting to convert a large float to an int in os.utime().
865
Raymond Hettinger3296e692005-06-29 23:29:56 +0000866- SF bug #1224347: hex longs now print with lowercase letters just
867 like their int counterparts.
868
Michael W. Hudson188d4362005-06-20 16:52:57 +0000869- SF bug #1163563: the original fix for bug #1010677 ("thread Module
870 Breaks PyGILState_Ensure()") broke badly in the case of multiple
871 interpreter states; back out that fix and do a better job (see
872 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
873 for a longer write-up of the problem).
874
Michael W. Hudsondf888462005-06-03 14:41:55 +0000875- SF patch #1180995: marshal now uses a binary format by default when
876 serializing floats.
877
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000878- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
879 the routines that promise to produce IEEE 754 binary representations
880 of floats now simply copy bytes around.
881
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000882- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
883 278.
884
Brett Cannonc3647ac2005-04-26 03:45:26 +0000885- patch #1109424: int, long, float, complex, and unicode now check for the
886 proper magic slot for type conversions when subclassed. Previously the
887 magic slot was ignored during conversion. Semantics now match the way
888 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000889 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000890 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000891 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000892
Barry Warsawc8d907c2005-04-19 23:43:40 +0000893- Descriptors defined in C with a PyGetSetDef structure, where the setter is
894 NULL, now raise an AttributeError when attempting to set or delete the
895 attribute. Previously a TypeError was raised, but this was inconsistent
896 with the equivalent pure-Python implementation.
897
Michael W. Hudson774479c2005-04-18 08:46:17 +0000898- It is now safe to call PyGILState_Release() before
899 PyEval_InitThreads() (note that if there is reason to believe there
900 are multiple threads around you still must call PyEval_InitThreads()
901 before using the Python API; this fix is for extension modules that
902 have no way of knowing if Python is multi-threaded yet).
903
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000904- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
905 disabled caused a crash.
906
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000907- Bug #1165306: instancemethod_new allowed the creation of a method

Brett Cannonf4189912005-04-09 02:30:16 +0000916 (e.g., ``class C(): pass`` is no longer a syntax error).
917 Patch #1176012 added support to the 'parser' module and 'compiler' package
918 (thanks to logistix for that added support).

Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000934 an ferror() call.
935
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000936- min() and max() now support key= arguments with the same meaning as in

Jeremy Hyltonab630502005-02-04 18:44:06 +0000947- The parser did not complain about future statements in illegal
948 positions. It once again reports a syntax error if a future
949 statement occurs after anything other than a doc string.
950
Neil Schemenauercf52c072005-08-12 17:34:58 +0000951- Change the %s format specifier for str objects so that it returns a
952 unicode instance if the argument is not an instance of basestring and
953 calling __str__ on the argument returns a unicode instance.
954
Tim Petersf4e69282006-02-27 17:15:31 +0000955- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
956 current thread state when the auto-GIL-state machinery knows about
957 it (since the thread state is being deleted, continuing to remember it
958 can't help, but can hurt if another thread happens to get created with
959 the same thread id).

1149-------
1150
Nick Coghlan43832302006-04-23 17:04:07 +00001151- PEP 338: new module runpy defines a run_module function to support
1152 executing modules which provide access to source code or a code object
1153 via the PEP 302 import mechanisms.

1163 in attribute values.
1164
Anthony Baxterc51ee692006-04-01 00:57:31 +00001165- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001166 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001167 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001168 module will not be built.
1169
Tim Petersc17976e2006-04-01 00:26:53 +00001170- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1171 aren't officially supported here, and trying to use them will probably
1172 raise an exception some day. But dicts have been allowed, and "mostly
1173 worked", so support for them won't go away without warning.
1174
Georg Brandl338ef7d2006-03-31 18:42:16 +00001175- Bug #1445068: getpass.getpass() can now be given an explicit stream

1193
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001194- email 4.0 package now integrated. This is largely the same as the email 3.0
1195 package that was included in Python 2.3, except that PEP 8 module names are
1196 now used (e.g. mail.message instead of email.Message). The MIME classes
1197 have been moved to a subpackage (e.g. email.mime.text instead of
1198 email.MIMEText). The old names are still supported for now. Several
1199 deprecated Message methods have been removed and lots of bugs have been
1200 fixed. More details can be found in the email package documentation.

1203 (a subclass of tuple) that provides incremental decoders and encoders
1204 (a way to use stateful codecs without the stream API). Python functions
1205 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1206 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1207 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001208

1210 a ValueError instead of a StopIteration now (like file and cString.String do).
1211 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1212 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00001286 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1287 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1288 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1289 Ronald L. Rivest offered this advice for Python:
1290
1291 "The consensus of researchers in this area (at least as
1292 expressed at the NIST Hash Function Workshop 10/31/05),
1293 is that SHA-256 is a good choice for the time being, but
1294 that research should continue, and other alternatives may
1295 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001296
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001297- Added a subset of Fredrik Lundh's ElementTree package. Available

1453
Raymond Hettingerbab41432005-02-05 01:31:19 +00001454- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1455
Guido van Rossumd0641422005-02-03 15:01:24 +00001456- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1457 disables recursive traversal through instance attributes, which can
1458 be exploited in various ways.
1459
Tim Peterse3547fd2005-12-16 23:13:57 +00001460- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001461 flags on the HTTP listening socket.
1462
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001463- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1464 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1465
Tim Peterse3547fd2005-12-16 23:13:57 +00001466- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001467 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

1472
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001473- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1474
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001475- Enhancements to the csv module:
1476
1477 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001478 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001479 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001480 + Dialect parameter parsing has been re-implemented to improve error
1481 reporting.
1482 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1483 dictates.
1484 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001485 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001486 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001487 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1488 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001489 + reader now allows \r characters to be quoted (previously it only allowed
1490 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001491 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001492 + Dialect classes passed to the module are no longer instantiated by
1493 the module before being parsed (the former validation scheme required
1494 this, but the mechanism was unreliable).
1495 + The dialect registry now contains instances of the internal
1496 C-coded dialect type, rather than references to python objects.
1497 + the internal c-coded dialect type is now immutable.
1498 + register_dialect now accepts the same keyword dialect specifications
1499 as the reader and writer, allowing the user to register dialects
1500 without first creating a dialect class.
1501 + a configurable limit to the size of parsed fields has been added -
1502 previously, an unmatched quote character could result in the entire
1503 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001504 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001505 the parser field size limit (returning the former limit). The initial
1506 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001507 + A line_num attribute has been added to the reader object, which tracks
1508 the number of lines read from the source iterator. This is not
1509 the same as the number of records returned, as records can span
1510 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001511 + reader and writer objects were not being registered with the cyclic-GC.
1512 This has been fixed.
1513
Brett Cannone6539c42005-01-08 02:43:53 +00001514- _DummyThread objects in the threading module now delete self.__block that is
1515 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1516 lock primitives tend to be limited in number and thus should not be wasted on
1517 a _DummyThread object. Fixes bug #1089632.
1518
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001519- The imghdr module now detects Exif files.
1520
Raymond Hettinger6065d322004-12-20 23:51:53 +00001521- StringIO.truncate() now correctly adjusts the size attribute.
1522 (Bug #951915).
1523
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001524- locale.py now uses an updated locale alias table (built using
1525 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1526 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001527 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001528
Raymond Hettinger3557f422004-12-07 12:02:02 +00001529- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1530
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001531- the pickle module no longer accepts the deprecated None option in the
1532 args tuple returned by __reduce__().
1533
Brett Cannon84667c02004-12-07 03:25:18 +00001534- optparse now optionally imports gettext. This allows its use in setup.py.
1535
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001536- the pickle module no longer uses the deprecated bin parameter.
1537
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001538- the shelve module no longer uses the deprecated binary parameter.
1539
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001540- the pstats module no longer uses the deprecated ignore() method.
1541
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001542- the filecmp module no longer uses the deprecated use_statcache argument.
1543
Raymond Hettinger664347b2004-12-04 21:21:53 +00001544- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1545 extended or overridden by subclasses. Formerly, the subclassed method would
1546 be ignored by the rest of the module. (Bug #1078905).
1547
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001548- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001549 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001550
Walter Dörwald36733692004-12-22 12:50:50 +00001551- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1552 once when a size argument is given. This prevents a buffer overflow in the
1553 tokenizer with very long source lines.
1554
Barry Warsaw538561e2006-01-01 21:48:54 +00001555- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1556 immediately after creating the object, without any intervening
1557 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001558
Skip Montanaro05885812005-01-16 20:48:27 +00001559- The reconvert.quote function can now emit triple-quoted strings. The
1560 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001561
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001562- ``UserString.MutableString`` now supports negative indices in
1563 ``__setitem__`` and ``__delitem__``
1564
Greg Ward40407942005-03-05 02:53:17 +00001565- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1566 correctly.
1567
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001568- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1569 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1570 character even if the user has passed a size parameter to get a proper
1571 line ending. Remove the special handling of a "\r\n" that has been split
1572 between two lines.
1573
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001574- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1575 about illegal code points. The codec now supports PEP 293 style error
1576 handlers.
1577
Walter Dörwald78a78b02005-09-01 12:04:29 +00001578- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001579 from the input stream, so that the output is a byte string in the correct
1580 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001581
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001582- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1583 considering it exactly like a '*'.
1584
Walter Dörwald007f8df2005-10-09 19:42:27 +00001585- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1586 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001587
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001588- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1589
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001590- Patch #1413711: Certain patterns of differences were making difflib
1591 touch the recursion limit.
1592
Walter Dörwald58917a62006-03-31 15:26:22 +00001593- Bug #947906: An object oriented interface has been added to the calendar
1594 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001595 called as a script (e.g. via ``python -mcalendar``). Localized month and
1596 weekday names can be ouput (even if an exotic encoding is used) using
1597 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001598
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001599Build

1601
Neal Norwitz602d3392006-03-31 08:21:40 +00001602- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1603 by using -mieee gcc option.
1604

1606
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001607- Build support for Win64-AMD64 was added.
1608
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001609- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1610
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001611- Patch #881820: look for openpty and forkpty also in libbsd.
1612
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001613- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1614 The zlib module is now builtin on Windows.
1615
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001616- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1617
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001618- Bug #1189330: configure did not correctly determine the necessary
1619 value of LINKCC if python was built with GCC 4.0.
1620
Trent Mick8321b422005-07-26 02:29:21 +00001621- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1622 vulnerability in zlib 1.2.1 and 1.2.2.
1623
Brett Cannon08cd5982005-04-24 22:26:38 +00001624- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1625 flags that change binary compatibility. Changes were also made to
1626 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001627 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001628
Bob Ippolitoed233462005-03-29 13:47:59 +00001629- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1630 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1631 no longer exists). This configure patch makes things right.
1632
Martin v. Löwise2713be2005-03-08 15:03:08 +00001633- Bug #1158607: Build with --disable-unicode again.
1634
Brett Cannon46d96232005-02-16 00:07:19 +00001635- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1636 defined. Discovered as a result of not being able to build on OS X.
1637
Brett Cannon516592f2004-12-07 00:42:59 +00001638- setup.py now uses the directories specified in LDFLAGS using the -L option
1639 and in CPPFLAGS using the -I option for adding library and include
1640 directories, respectively, for compiling extension modules against. This has
1641 led to the core being compiled using the values in CPPFLAGS. It also removes
1642 the need for the special-casing of both DarwinPorts and Fink for darwin since
1643 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1644 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1645 Fink, ``-I/opt/local/include`` for DarwinPorts).
1646
Brett Cannon43802422005-02-10 20:48:03 +00001647- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1648 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1649 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1650 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001652C API
1653-----
1654
Tim Petersc9d78aa2006-03-26 23:27:58 +00001655- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1656 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1657 is obtained via the ``PyObject_`` family, it must be released via the
1658 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1659 always been officially true, but when Python's small-object allocator was
1660 introduced, an attempt was made to cater to a few extension modules
1661 discovered at the time that obtained memory via ``PyObject_New`` but
1662 released it via ``PyMem_DEL``. It's years later, and if such code still
1663 exists it will fail now (probably with segfaults, but calling wrong
1664 low-level memory management functions can yield many symptoms).
1665
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001666- Added a C API for set and frozenset objects.
1667
Raymond Hettinger66517482004-12-03 11:45:13 +00001668- Removed PyRange_New().
1669
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001670- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1671 mapping argument now. This string is used as a mapping table. Byte values
1672 greater than the length of the string and 0xFFFE are treated as undefined
1673 mappings.
