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
22 be released.
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. Löwis388a8c22006-07-06 19:28:03 +000042- Bug #1515998: Properly generate logical ids for files in bdist_msi.
43
Nick Coghlan2d792252006-07-06 13:47:18 +000044- warnings.py now ignores ImportWarning by default
45
Thomas Heller5becdbe2006-07-06 08:48:35 +000046- Patch #1517790: It is now possible to use custom objects in the ctypes
47 foreign function argtypes sequence as long as they provide a from_param
48 method, no longer is it required that the object is a ctypes type.
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
70 socket again, which then gets closed as it becomes unreferenced.
71
Thomas Hellerbde08132006-06-29 18:34:15 +000072- The '_ctypes' extension module now works when Python is configured
73 with the --without-threads option.
74
Fred Drake10497c82006-06-29 02:57:48 +000075- Bug #1504333: Make sgmllib support angle brackets in quoted
76 attribute values.
77
78- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
79 sgmllib ('[' and ']' were not accepted).
80
Georg Brandl1be63af2006-06-28 20:23:25 +000081- Fix a bug in the turtle module's end_fill function.
82
Brett Cannon53ab5b72006-06-22 16:49:14 +000083- Bug #1510580: The 'warnings' module improperly required that a Warning
84 category be either a types.ClassType and a subclass of Warning. The proper
85 check is just that it is a subclass with Warning as the documentation states.
86
Georg Brandlad29e632006-06-21 17:45:17 +000087- The compiler module now correctly compiles the new try-except-finally
88 statement (bug #1509132).
89
Neal Norwitz60373cd2006-06-22 06:30:50 +000090- The wsgiref package is now installed properly on Unix.
91
Vinay Sajip28e57612006-07-01 10:45:20 +000092- A bug was fixed in logging.config.fileConfig() which caused a crash on
93 shutdown when fileConfig() was called multiple times.
94
Gerhard Häring762fbd32006-07-02 17:48:30 +000095- The sqlite3 module did cut off data from the SQLite database at the first
96 null character before sending it to a custom converter. This has been fixed
97 now.
98
Neal Norwitz0f8b31a2006-06-28 06:28:31 +000099Extension Modules
100-----------------
101
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000102- Bug #1513646: os.access on Windows now correctly determines write
103 access, again.
104
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000105- Bug #1512695: cPickle.loads could crash if it was interrupted with
106 a KeyboardInterrupt.
107
Neal Norwitza12aa882006-07-06 06:45:08 +0000108- Bug #1296433: parsing XML with a non-default encoding and
109 a CharacterDataHandler could crash the interpreter in pyexpat.
110
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000111- Patch #1516912: improve Modules support for OpenVMS.
112
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000113Build
114-----
115
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000116- 'configure' now detects the zlib library the same way as distutils.
117 Previously, the slight difference could cause compilation errors of the
118 'zlib' module on systems with more than one version of zlib.
119
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000120- The MSI compileall step was fixed to also support a TARGETDIR
121 with spaces in it.
122
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000123- Bug #1517388: sqlite3.dll is now installed on Windows independent
124 of Tcl/Tk.
125
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000126- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000127 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000128
Neal Norwitzb15ac312006-06-29 04:10:08 +0000129Tests
130-----
131
132- Call os.waitpid() at the end of tests that spawn child processes in order
133 to minimize resources (zombies).
134
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000135Documentation
136-------------
137
Nick Coghlan2d792252006-07-06 13:47:18 +0000138- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
139 documentation for the warnings module.
140
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000141- Patch #1509163: MS Toolkit Compiler no longer available.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000144What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000145================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000146
Anthony Baxterd1136802006-06-19 12:04:15 +0000147*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000148
149Core and builtins
150-----------------
151
Georg Brandla56b9152006-06-19 06:35:54 +0000152- Patch #1507676: Error messages returned by invalid abstract object operations
153 (such as iterating over an integer) have been improved and now include the
154 type of the offending object to help with debugging.
155
Brett Cannonea3912b2006-06-13 21:46:41 +0000156- Bug #992017: A classic class that defined a __coerce__() method that returned
157 its arguments swapped would infinitely recurse and segfault the interpreter.
158
Neal Norwitz909eb122006-06-12 02:13:21 +0000159- Fix the socket tests so they can be run concurrently.
160
Neal Norwitzb9845e72006-06-12 02:11:18 +0000161- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000162 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000163
Brett Cannon22565aa2006-06-09 22:31:23 +0000164- Bug #532646: object.__call__() will continue looking for the __call__
165 attribute on objects until one without one is found. This leads to recursion
166 when you take a class and set its __call__ attribute to an instance of the
167 class. Originally fixed for classic classes, but this fix is for new-style.
168 Removes the infinite_rec_3 crasher.
169
Georg Brandl24250812006-06-09 18:45:48 +0000170- The string and unicode methods startswith() and endswith() now accept
171 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
172
Brett Cannonde3b0522006-06-08 17:00:45 +0000173- Buffer objects, at the C level, never used the char buffer
174 implementation even when the char buffer for the wrapped object was
175 explicitly requested (originally returned the read or write buffer).
176 Now a TypeError is raised if the char buffer is not present but is
177 requested.
178
Georg Brandlddbaa662006-06-04 21:56:52 +0000179- Patch #1346214: Statements like "if 0: suite" are now again optimized
180 away like they were in Python 2.4.
181
Georg Brandlb7c8f542006-05-27 12:30:25 +0000182- Builtin exceptions are now full-blown new-style classes instead of
183 instances pretending to be classes, which speeds up exception handling
184 by about 80% in comparison to 2.5a2.
185
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000186- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
187 Unicode 4.1.
188
Georg Brandlf4ef1162006-05-26 18:03:31 +0000189- Patch #921466: sys.path_importer_cache is now used to cache valid and
190 invalid file paths for the built-in import machinery which leads to
191 fewer open calls on startup.
192
Tim Peters696cf432006-05-24 21:10:40 +0000193- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
194 of-2 bases. The largest speedup is for inputs with about 1000 decimal
195 digits. Conversion from non-power-of-2 bases remains quadratic-time in
196 the number of input digits (it was and remains linear-time for bases
197 2, 4, 8, 16 and 32).
198
Tim Petersb713ec22006-05-23 18:45:30 +0000199- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
200 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
201 an integer close to ``sys.maxint``. This was repaired by patch
202 #1335972, which also gives a nice speedup.
203
Richard Jonescebbefc2006-05-23 18:28:17 +0000204- Patch #1337051: reduced size of frame objects.
205
206- PyErr_NewException now accepts a tuple of base classes as its
207 "base" parameter.
208
Richard Jones7c88dcc2006-05-23 10:37:38 +0000209- Patch #876206: function call speedup by retaining allocated frame
210 objects.
211
Georg Brandl7b90e162006-05-18 07:01:27 +0000212- Bug #1462152: file() now checks more thoroughly for invalid mode
213 strings and removes a possible "U" before passing the mode to the
214 C library function.
215
Neal Norwitz1004a532006-05-15 07:17:23 +0000216- Patch #1488312, Fix memory alignment problem on SPARC in unicode
217
Neal Norwitz373f0a72006-05-15 07:04:36 +0000218- Bug #1487966: Fix SystemError with conditional expression in assignment
219
Martin v. Löwis879768d2006-05-11 13:28:43 +0000220- WindowsError now has two error code attributes: errno, which carries
221 the error values from errno.h, and winerror, which carries the error
222 values from winerror.h. Previous versions put the winerror.h values
223 (from GetLastError()) into the errno attribute.
224
Martin v. Löwis77736712006-05-04 05:51:03 +0000225- Patch #1475845: Raise IndentationError for unexpected indent.
226
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000227- Patch #1479181: split open() and file() from being aliases for each other.
228
Tim Peters44bd9862006-06-01 13:49:23 +0000229- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
230 methods were always silently ignored by dictionaries when comparing keys.
231 They are now passed through (except when using the C API function
232 ``PyDict_GetItem()``, whose semantics did not change).
233
234- Bug #1456209: In some obscure cases it was possible for a class with a
235 custom ``__eq__()`` method to confuse dict internals when class instances
236 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
237 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000239Extension Modules
240-----------------
241
Trent Mick960a3f82006-06-28 20:30:41 +0000242- Bug #1295808: expat symbols should be namespaced in pyexpat
243
244- Patch #1462338: Upgrade pyexpat to expat 2.0.0
245
Brett Cannon6ee7d012006-06-08 16:23:04 +0000246- Change binascii.hexlify to accept a read-only buffer instead of only a char
247 buffer and actually follow its documentation.
248
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000249- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
250
Nick Coghlanc649ec52006-05-29 12:43:05 +0000251- Patch #1478788 (modified version): The functional extension module has
252 been renamed to _functools and a functools Python wrapper module added.
253 This provides a home for additional function related utilities that are
254 not specifically about functional programming. See PEP 309.
255
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000256- Patch #1493701: performance enhancements for struct module.
257
Georg Brandl378d5922006-05-17 14:26:50 +0000258- Patch #1490224: time.altzone is now set correctly on Cygwin.
259
Georg Brandl8d3342b2006-05-16 07:38:27 +0000260- Patch #1435422: zlib's compress and decompress objects now have a
261 copy() method.
262
Andrew MacIntyre92913322006-06-13 15:04:24 +0000263- Patch #1454481: thread stack size is now tunable at runtime for thread
264 enabled builds on Windows and systems with Posix threads support.
265
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000266- On Win32, os.listdir now supports arbitrarily-long Unicode path names
267 (up to the system limit of 32K characters).
268
269- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
270 As a result, these functions now raise WindowsError instead of OSError.
271
Tim Peters7a822da2006-05-25 21:50:17 +0000272- ``time.clock()`` on Win64 should use the high-performance Windows
273 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
274 Windows platforms).
275
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000276- Calling Tk_Init twice is refused if the first call failed as that
277 may deadlock.
278
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000279- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
280 accept it without potentially using an uninitialized pointer.
281
282- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
283 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
284 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000285
Gregory P. Smith372b5832006-06-05 18:48:21 +0000286- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000287 [pybsddb project SF patch number 1466734]
288
Gregory P. Smith372b5832006-06-05 18:48:21 +0000289- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
290 parameter is supplied. [SF pybsddb bug #1477863]
291
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000292- bsddb: the __len__ method of a DB object has been fixed to return correct
293 results. It could previously incorrectly return 0 in some cases.
294 Fixes SF bug 1493322 (pybsddb bug 1184012).
295
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000296- bsddb: the bsddb.dbtables Modify method now raises the proper error and
297 aborts the db transaction safely when a modifier callback fails.
298 Fixes SF python patch/bug #1408584.
299
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000300- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000301 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000302 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
303 database calls that would previously deadlock. [SF python bug #775414]
304
Vinay Sajip28e57612006-07-01 10:45:20 +0000305- Patch #1446489: add support for the ZIP64 extensions to zipfile.

325
Georg Brandl83cc0d02006-06-14 08:50:03 +0000326- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
327 mime.types file for determining MIME types.
328
Georg Brandl2605ca82006-06-14 06:08:31 +0000329- Bug #1339007: Shelf objects now don't raise an exception in their
330 __del__ method when initialization failed.
331
Martin v. Löwisd8251432006-06-14 05:21:04 +0000332- Patch #1455898: The MBCS codec now supports the incremental mode for
333 double-byte encodings.
334
Tim Peters43898b42006-06-14 04:09:25 +0000335- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
336 guarantee that adjacent triples in the return list always describe
337 non-adjacent blocks. Previously, a pair of matching blocks could end
338 up being described by multiple adjacent triples that formed a partition
339 of the matching pair.
340
Greg Ward0e0c9f42006-06-11 16:24:11 +0000341- Bug #1498146: fix optparse to handle Unicode strings in option help,
342 description, and epilog.
343
Greg Wardd1c797e2006-06-11 14:42:41 +0000344- Bug #1366250: minor optparse documentation error.
345
Greg Ward7f547402006-06-11 00:40:49 +0000346- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
347 clarify docs.
348
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000349- The wsgiref package has been added to the standard library.
350
Nick Coghlan676725d2006-06-08 13:54:49 +0000351- The functions update_wrapper() and wraps() have been added to the functools
352 module. These make it easier to copy relevant metadata from the original
353 function when writing wrapper functions.
354
Tim Petersd6a9eef2006-06-05 01:48:21 +0000355- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
356 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000357
Martin v. Löwis3f767792006-06-04 19:36:28 +0000358- Patch #1359618: Speed up charmap encoder by using a trie structure
359 for lookup.
360
Tim Petersd609b1a2006-06-02 23:22:51 +0000361- The functions in the ``pprint`` module now sort dictionaries by key
362 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
363 if and only if its display required more than one line, although that
364 wasn't documented. The new behavior increases predictability; e.g.,
365 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
366
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000367- Patch #1497027: try HTTP digest auth before basic auth in urllib2

371 default HTTP and HTTPS ports.
372
George Yoshidaf3c65de2006-05-28 16:39:09 +0000373- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.

376
Georg Brandlb89316f2006-05-17 15:51:16 +0000377- Patch #1180296: Two new functions were added to the locale module:
378 format_string() to get the effect of "format % items" but locale-aware,
379 and currency() to format a monetary number with currency sign.
380
Georg Brandle3a25832006-05-17 14:56:04 +0000381- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
382 and several features added, such as speed and geometry control.
383
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000384- Patch #1488881: add support for external file objects in bz2 compressed
385 tarfiles.
386
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000387- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
388 stdout arguments, making it possible to redirect input and output
389 for remote debugging.
390
391- Patch #1484695: Update the tarfile module to version 0.8. This fixes
392 a couple of issues, notably handling of long file names using the
393 GNU LONGNAME extension.
394
395- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
396 new flag when ``name`` is already the name of an option flag.
397
398- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
399 package.
400
401- Patch #1472854: make the rlcompleter.Completer class usable on non-
402 UNIX platforms.
403
404- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
405
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000406- Bug #1472827: correctly escape newlines and tabs in attribute values in
407 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000437What's New in Python 2.5 alpha 2?
438=================================
439
440*Release date: 27-APR-2006*
441
442Core and builtins
443-----------------
444
Thomas Heller1b046642006-04-18 18:51:06 +0000445- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
446 by converting these apis from macros into exported functions again:
447
448 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
449 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
450 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
451 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
452 PyRun_String Py_CompileString
453
Martin v. Löwis45294a92006-04-18 06:24:08 +0000454- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
455
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000456- All uses of PyStructSequence_InitType have been changed to initialize
457 the type objects only once, even if the interpreter is initialized
458 multiple times.
459
Neal Norwitz61546162006-04-14 05:20:28 +0000460- Bug #1454485, array.array('u') could crash the interpreter. This was
461 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
462 to unicode when it didn't make sense. 'u#' now requires a unicode string.
463
464- Py_UNICODE is unsigned. It was always documented as unsigned, but
465 due to a bug had a signed value in previous versions.
466
Tim Peters3a5e8b12006-04-11 01:44:07 +0000467- Patch #837242: ``id()`` of any Python object always gives a positive
468 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
469 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000470 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000471 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000472
Tim Peters3a5e8b12006-04-11 01:44:07 +0000473 def __hash__(self):
474 return id(self) # WRONG
475
476 because a hash result must be a (short) Python int but it was always
477 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000478 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000479 was always usable as a hash value before this patch. That's no longer
480 necessarily so.
481
482- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000483 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000484 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000485 #1454844)
486
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000487- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
488 involving generators that have paused outside of any ``try`` or ``with``
489 blocks. (In 2.5a1, a paused generator that was part of a reference
490 cycle could not be garbage collected, regardless of whether it was
491 paused in a ``try`` or ``with`` block.)

508 a temporary db (file=None) with the 'n' flag to truncate on open.
509
510- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
511 as older versions cause excessive test failures.

Tim Peters711bf302006-04-25 03:31:36 +0000519- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
520 a doctest to be skipped (the code is not run, and the expected output
521 or exception is ignored).
522
Nick Coghlanda2268f2006-04-24 04:37:15 +0000523- Fixed contextlib.nested to cope with exceptions being raised and
524 caught inside exit handlers.
525
Greg Wardab05edc2006-04-23 03:47:58 +0000526- Updated optparse module to Optik 1.5.1 (allow numeric constants in
527 hex, octal, or binary; add ``append_const`` action; keep going if
528 gettext cannot be imported; added ``OptionParser.destroy()`` method;
529 added ``epilog`` for better help generation).
530
Tim Peters21fbd572006-04-21 21:18:10 +0000531- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
532 called from a thread spawned as a side effect of importing a module.
533
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000534- The pydoc module now supports documenting packages contained in
535 .zip or .egg files.
536
537- The pkgutil module now has several new utility functions, such
538 as ``walk_packages()`` to support working with packages that are either
539 in the filesystem or zip files.
540
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000541- The mailbox module can now modify and delete messages from
542 mailboxes, in addition to simply reading them. Thanks to Gregory
543 K. Johnson for writing the code, and to the 2005 Google Summer of
544 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000545
Tim Petersc7605f22006-04-17 21:12:33 +0000546- The ``__del__`` method of class ``local`` in module ``_threading_local``
547 returned before accomplishing any of its intended cleanup.
548
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000549- Patch #790710: Add breakpoint command lists in pdb.

554
Anthony Baxtere29002c2006-04-12 12:07:31 +0000555- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
556 Windows. Bug #1469163.
557
Phillip J. Eby47032112006-04-11 01:07:43 +0000558- The warnings, linecache, inspect, traceback, site, and doctest modules
559 were updated to work correctly with modules imported from zipfiles or
560 via other PEP 302 __loader__ objects.

583 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000584 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000585 CXX from --with-cxx-main, see description in README.
586

Nick Coghlanda2268f2006-04-24 04:37:15 +0000598- test_contextlib now checks contextlib.nested can cope with exceptions
599 being raised and caught inside exit handlers.
600
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000601- test_cmd_line now checks operation of the -m and -c command switches
602
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000603- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
604 it separately and by hand. It also wasn't cleaning up its changes to
605 the current Decimal context.
606
Thomas Woutersabd08882006-04-26 15:53:30 +0000607- regrtest.py now has a -M option to run tests that test the new limits of
608 containers, on 64-bit architectures. Running these tests is only sensible
609 on 64-bit machines with more than two gigabytes of memory. The argument
610 passed is the maximum amount of memory for the tests to use.

625 line with the implementation and/or python-dev discussions.
626
Tim Peters8dc73d22006-04-24 02:03:16 +0000627- Bug #1337990: clarified that ``doctest`` does not support examples
628 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000631What's New in Python 2.5 alpha 1?
632=================================
633
Anthony Baxterebed3f62006-04-03 15:03:44 +0000634*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000635
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000636Core and builtins
637-----------------
638
Nick Coghlan43832302006-04-23 17:04:07 +0000639- PEP 338: -m command line switch now delegates to runpy.run_module
640 allowing it to support modules in packages and zipfiles
641
Martin v. Löwisc661b882006-04-20 04:54:23 +0000642- On Windows, .DLL is not an accepted file name extension for
643 extension modules anymore; extensions are only found if they
644 end in .PYD.
645
Martin v. Löwisea62d252006-04-03 10:56:49 +0000646- Bug #1421664: sys.stderr.encoding is now set to the same value as
647 sys.stdout.encoding.
648
Neal Norwitz92e212f2006-04-03 04:48:37 +0000649- __import__ accepts keyword arguments.
650
Georg Brandlccadf842006-03-31 18:54:53 +0000651- Patch #1460496: round() now accepts keyword arguments.
652
Anthony Baxter262c00a2006-03-30 10:53:17 +0000653- Fixed bug #1459029 - unicode reprs were double-escaped.
654
Hye-Shik Changd478f342006-03-23 12:32:36 +0000655- Patch #1396919: The system scope threads are reenabled on FreeBSD
656 5.4 and later versions.
657
Neal Norwitze98ccf62006-03-23 05:39:47 +0000658- Bug #1115379: Compiling a Unicode string with an encoding declaration
659 now gives a SyntaxError.
660
Georg Brandlabd1ff82006-03-18 07:59:59 +0000661- Previously, Python code had no easy way to access the contents of a
662 cell object. Now, a ``cell_contents`` attribute has been added
663 (closes patch #1170323).
664
Tim Peterscf79aac2006-03-16 01:14:46 +0000665- Patch #1123430: Python's small-object allocator now returns an arena to
666 the system ``free()`` when all memory within an arena becomes unused
667 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
668 freed. Some applications will see a drop in virtual memory size now,
669 especially long-running applications that, from time to time, temporarily
670 use a large number of small objects. Note that when Python returns an
671 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000672 platform C library will in turn return that memory to the operating system.
673 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000674 appears to be effective at least on Microsoft C and gcc-based systems.
675 Thanks to Evan Jones for hard work and patience.
676
Georg Brandl533ff6f2006-03-08 18:09:27 +0000677- Patch #1434038: property() now uses the getter's docstring if there is
678 no "doc" argument given. This makes it possible to legitimately use
679 property() as a decorator to produce a read-only property.
680
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000681- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
682 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
683 of requiring an int or long in slicing and a few other contexts, enabling
684 other objects (e.g. Numeric Python's integers) to be used as slice indices.
685
Neal Norwitz995acdf2006-03-07 05:01:00 +0000686- Fixed various bugs reported by Coverity's Prevent tool.
687
Brett Cannonbf364092006-03-01 04:25:17 +0000688- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
689 new exception base class, BaseException, which has a new message attribute.
690 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
691 Raising a string exception now raises a DeprecationWarning.
692
Thomas Woutersfb609f42006-02-28 16:37:25 +0000693- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
694 explicitly relative, using 'from .module import name' to mean 'from the same
695 package as this module is in. Imports without dots still default to the
696 old relative-then-absolute, unless 'from __future__ import
697 absolute_import' is used.
698
Brett Cannona7446e32006-02-27 23:39:10 +0000699- Properly check if 'warnings' raises an exception (usually when a filter set
700 to "error" is triggered) when raising a warning for raising string
701 exceptions.
702
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000703- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000704 The name was removed from Include/code.h.
705
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000706- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000707
Guido van Rossum1968ad32006-02-25 22:38:04 +0000708- Patch 1433928:
709 - The copy module now "copies" function objects (as atomic objects).
710 - dict.__getitem__ now looks for a __missing__ hook before raising
711 KeyError.
712
Tim Peters84ef21c2006-02-28 20:39:06 +0000713- PEP 343: with statement implemented. Needs ``from __future__ import
714 with_statement``. Use of 'with' as a variable will generate a warning.
715 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000716 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000717 The following objects have __context__ methods:
718 - The built-in file type.
719 - The thread.LockType type.
720 - The following types defined by the threading module:
721 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
722 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000723
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000724- Fix the encodings package codec search function to only search
725 inside its own package. Fixes problem reported in patch #1433198.
726
727 Note: Codec packages should implement and register their own
728 codec search function. PEP 100 has the details.
729
Tim Peters9ea89d22006-06-04 03:26:02 +0000730- PEP 353: Using ``Py_ssize_t`` as the index type.
731
732- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
733 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
734 now allow Python to make use of memory blocks exceeding 2**32 bytes for
735 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
736 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000737
Neal Norwitzfc76d632006-01-10 06:03:13 +0000738- Patch #1400181, fix unicode string formatting to not use the locale.
739 This is how string objects work. u'%f' could use , instead of .
740 for the decimal point. Now both strings and unicode always use periods.
741
Neal Norwitz671b9e32006-01-09 07:07:12 +0000742- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
743 configure would break checking curses.h.
744
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000745- Bug #959576: The pwd module is now builtin. This allows Python to be
746 built on UNIX platforms without $HOME set.
747
Neal Norwitzc10978f2005-12-19 06:07:16 +0000748- Bug #1072182, fix some potential problems if characters are signed.
749
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000750- Bug #889500, fix line number on SyntaxWarning for global declarations.
751
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000752- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
753
Neal Norwitze7214a12005-12-18 05:03:17 +0000754- Support for converting hex strings to floats no longer works.
755 This was not portable. float('0x3') now raises a ValueError.
756
Barry Warsaw2a38a862005-12-18 01:27:35 +0000757- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000758 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000759 is now displayed in interactive prompt banner.
760
Georg Brandlfa166682005-12-17 21:45:17 +0000761- Implementation of PEP 341 - Unification of try/except and try/finally.
762 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000763 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000764
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000765- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
766 now encodes backslash correctly.
767
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000768- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
769
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000770- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000771 and long longs.
772
Neal Norwitz67715f02005-11-09 06:59:35 +0000773- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000774 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000775 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000776
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000777- Replaced most Unicode charmap codecs with new ones using the
778 new Unicode translate string feature in the builtin charmap
779 codec; the codecs were created from the mapping tables available
780 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
781 encodings now include a mapping for the Apple logo)
782
Tim Peterse3547fd2005-12-16 23:13:57 +0000783- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000784
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000785- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000786
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000787- A new AST parser implementation was completed. The abstract
788 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000789 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000790
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000791- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000792 The following code now raises a SyntaxError: foo(a = i for i in range(10))
793
Neal Norwitz708e51a2005-10-03 04:48:15 +0000794- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
795
Neal Norwitz11bd1192005-10-03 00:54:56 +0000796- SF Bug #887946: fix segfault when redirecting stdin from a directory.
797 Provide a warning when a directory is passed on the command line.
798
Neal Norwitz40d37812005-10-02 01:48:49 +0000799- Fix segfault with invalid coding.
800
801- SF bug #772896: unknown encoding results in MemoryError.
802
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000803- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000804 supported a __len__() method which evaluated to False when the iterator
805 was empty.
806
Guido van Rossum630db602005-09-20 18:49:54 +0000807- On 64-bit platforms, when __len__() returns a value that cannot be
808 represented as a C int, raise OverflowError.
809
Skip Montanarof8948ca2005-09-19 03:54:46 +0000810- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000811 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000812
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000813- SF bug #893549: parsing keyword arguments was broken with a few format
814 codes.
815
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000816- Changes donated by Elemental Security to make it work on AIX 5.3
817 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
818 bug #105470: test_pwd fails on 64bit system (Opteron).
819
Guido van Rossum539c6622005-09-14 17:49:54 +0000820- Changes donated by Elemental Security to make it work on HP-UX 11 on
821 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
822
Georg Brandl4550b8d2005-08-26 06:43:52 +0000823- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000824 (fixes bug #1119418).
825
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000826- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
827
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000828- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
829 exceptions that cause a function to exit.
830
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000831- The implementation of set() and frozenset() was revised to use its
832 own internal data structure. Memory consumption is reduced by 1/3
833 and there are modest speed-ups as well. The API is unchanged.
834
Tim Petersde7990b2005-07-17 23:45:23 +0000835- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
836
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000837- SF bug #1229429: PyObject_CallMethod failed to decrement some
838 reference counts in some error exit cases.
839
Tim Petersecc6e6a2005-07-10 22:30:55 +0000840- SF bug #1185883: Python's small-object memory allocator took over
841 a block managed by the platform C library whenever a realloc specified
842 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000843 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000844 portable way to copy data from the C-managed block into Python's
845 small-object space without risking a memory fault. Python's small-object
846 realloc now leaves such blocks under the control of the platform C
847 realloc.
848
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000849- SF bug #1232517: An overflow error was not detected properly when
850 attempting to convert a large float to an int in os.utime().
851
Raymond Hettinger3296e692005-06-29 23:29:56 +0000852- SF bug #1224347: hex longs now print with lowercase letters just
853 like their int counterparts.
854
Michael W. Hudson188d4362005-06-20 16:52:57 +0000855- SF bug #1163563: the original fix for bug #1010677 ("thread Module
856 Breaks PyGILState_Ensure()") broke badly in the case of multiple
857 interpreter states; back out that fix and do a better job (see
858 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
859 for a longer write-up of the problem).
860
Michael W. Hudsondf888462005-06-03 14:41:55 +0000861- SF patch #1180995: marshal now uses a binary format by default when
862 serializing floats.
863
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000864- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
865 the routines that promise to produce IEEE 754 binary representations
866 of floats now simply copy bytes around.
867
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000868- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
869 278.
870
Brett Cannonc3647ac2005-04-26 03:45:26 +0000871- patch #1109424: int, long, float, complex, and unicode now check for the
872 proper magic slot for type conversions when subclassed. Previously the
873 magic slot was ignored during conversion. Semantics now match the way
874 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000875 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000876 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000877 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000878
Barry Warsawc8d907c2005-04-19 23:43:40 +0000879- Descriptors defined in C with a PyGetSetDef structure, where the setter is
880 NULL, now raise an AttributeError when attempting to set or delete the
881 attribute. Previously a TypeError was raised, but this was inconsistent
882 with the equivalent pure-Python implementation.
883
Michael W. Hudson774479c2005-04-18 08:46:17 +0000884- It is now safe to call PyGILState_Release() before
885 PyEval_InitThreads() (note that if there is reason to believe there
886 are multiple threads around you still must call PyEval_InitThreads()
887 before using the Python API; this fix is for extension modules that
888 have no way of knowing if Python is multi-threaded yet).
889
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000890- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
891 disabled caused a crash.
892
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000893- Bug #1165306: instancemethod_new allowed the creation of a method
894 with im_class == im_self == NULL, which caused a crash when called.
895
Tim Petersecc6e6a2005-07-10 22:30:55 +0000896- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000897 fixes the crash seen in bug #1165761
898
Raymond Hettinger96229b12005-03-11 06:49:40 +0000899- Added two new builtins, any() and all().
900

Brett Cannonf4189912005-04-09 02:30:16 +0000902 (e.g., ``class C(): pass`` is no longer a syntax error).
903 Patch #1176012 added support to the 'parser' module and 'compiler' package
904 (thanks to logistix for that added support).

Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000920 an ferror() call.
921
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000922- min() and max() now support key= arguments with the same meaning as in

Jeremy Hyltonab630502005-02-04 18:44:06 +0000933- The parser did not complain about future statements in illegal

940
Tim Petersf4e69282006-02-27 17:15:31 +0000941- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
942 current thread state when the auto-GIL-state machinery knows about
943 it (since the thread state is being deleted, continuing to remember it
944 can't help, but can hurt if another thread happens to get created with
945 the same thread id).

1135-------
1136
Nick Coghlan43832302006-04-23 17:04:07 +00001137- PEP 338: new module runpy defines a run_module function to support
1138 executing modules which provide access to source code or a code object
1139 via the PEP 302 import mechanisms.

Georg Brandl828fdef2006-04-01 08:59:03 +00001152 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001153 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001154 module will not be built.
1155
Tim Petersc17976e2006-04-01 00:26:53 +00001156- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1157 aren't officially supported here, and trying to use them will probably
1158 raise an exception some day. But dicts have been allowed, and "mostly
1159 worked", so support for them won't go away without warning.
1160
Georg Brandl338ef7d2006-03-31 18:42:16 +00001161- Bug #1445068: getpass.getpass() can now be given an explicit stream

1179
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001180- email 4.0 package now integrated. This is largely the same as the email 3.0
1181 package that was included in Python 2.3, except that PEP 8 module names are
1182 now used (e.g. mail.message instead of email.Message). The MIME classes
1183 have been moved to a subpackage (e.g. email.mime.text instead of
1184 email.MIMEText). The old names are still supported for now. Several
1185 deprecated Message methods have been removed and lots of bugs have been
1186 fixed. More details can be found in the email package documentation.

1189 (a subclass of tuple) that provides incremental decoders and encoders
1190 (a way to use stateful codecs without the stream API). Python functions
1191 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1192 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1193 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001194
Walter Dörwald067db482006-03-15 22:17:27 +00001195- Patch #1359365: Calling next() on a closed StringIO.String object raises
1196 a ValueError instead of a StopIteration now (like file and cString.String do).
1197 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1198 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00001272 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1273 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1274 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1275 Ronald L. Rivest offered this advice for Python:
1276
1277 "The consensus of researchers in this area (at least as
1278 expressed at the NIST Hash Function Workshop 10/31/05),
1279 is that SHA-256 is a good choice for the time being, but
1280 that research should continue, and other alternatives may
1281 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001282

Raymond Hettingerbab41432005-02-05 01:31:19 +00001440- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1441
Guido van Rossumd0641422005-02-03 15:01:24 +00001442- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1443 disables recursive traversal through instance attributes, which can
1444 be exploited in various ways.
1445
Tim Peterse3547fd2005-12-16 23:13:57 +00001446- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001447 flags on the HTTP listening socket.
1448
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001449- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1450 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1451
Tim Peterse3547fd2005-12-16 23:13:57 +00001452- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001453 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

1460
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001461- Enhancements to the csv module:
1462
1463 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001464 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001465 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001466 + Dialect parameter parsing has been re-implemented to improve error
1467 reporting.
1468 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1469 dictates.
1470 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001471 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001472 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001473 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1474 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001475 + reader now allows \r characters to be quoted (previously it only allowed
1476 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001477 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001478 + Dialect classes passed to the module are no longer instantiated by
1479 the module before being parsed (the former validation scheme required
1480 this, but the mechanism was unreliable).
1481 + The dialect registry now contains instances of the internal
1482 C-coded dialect type, rather than references to python objects.
1483 + the internal c-coded dialect type is now immutable.
1484 + register_dialect now accepts the same keyword dialect specifications
1485 as the reader and writer, allowing the user to register dialects
1486 without first creating a dialect class.
1487 + a configurable limit to the size of parsed fields has been added -
1488 previously, an unmatched quote character could result in the entire
1489 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001490 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001491 the parser field size limit (returning the former limit). The initial
1492 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001493 + A line_num attribute has been added to the reader object, which tracks
1494 the number of lines read from the source iterator. This is not
1495 the same as the number of records returned, as records can span
1496 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001497 + reader and writer objects were not being registered with the cyclic-GC.
1498 This has been fixed.
1499
Brett Cannone6539c42005-01-08 02:43:53 +00001500- _DummyThread objects in the threading module now delete self.__block that is
1501 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1502 lock primitives tend to be limited in number and thus should not be wasted on
1503 a _DummyThread object. Fixes bug #1089632.
1504
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001505- The imghdr module now detects Exif files.
1506
Raymond Hettinger6065d322004-12-20 23:51:53 +00001507- StringIO.truncate() now correctly adjusts the size attribute.
1508 (Bug #951915).
1509
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001510- locale.py now uses an updated locale alias table (built using
1511 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1512 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001513 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001514
Raymond Hettinger3557f422004-12-07 12:02:02 +00001515- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1516
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001517- the pickle module no longer accepts the deprecated None option in the
1518 args tuple returned by __reduce__().
1519
Brett Cannon84667c02004-12-07 03:25:18 +00001520- optparse now optionally imports gettext. This allows its use in setup.py.
1521
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001522- the pickle module no longer uses the deprecated bin parameter.
1523
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001524- the shelve module no longer uses the deprecated binary parameter.
1525
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001526- the pstats module no longer uses the deprecated ignore() method.
1527
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001528- the filecmp module no longer uses the deprecated use_statcache argument.
1529
Raymond Hettinger664347b2004-12-04 21:21:53 +00001530- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1531 extended or overridden by subclasses. Formerly, the subclassed method would
1532 be ignored by the rest of the module. (Bug #1078905).
1533
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001534- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001535 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001536
Walter Dörwald36733692004-12-22 12:50:50 +00001537- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1538 once when a size argument is given. This prevents a buffer overflow in the
1539 tokenizer with very long source lines.
1540
Barry Warsaw538561e2006-01-01 21:48:54 +00001541- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1542 immediately after creating the object, without any intervening
1543 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001544
Skip Montanaro05885812005-01-16 20:48:27 +00001545- The reconvert.quote function can now emit triple-quoted strings. The
1546 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001547
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001548- ``UserString.MutableString`` now supports negative indices in
1549 ``__setitem__`` and ``__delitem__``
1550
Greg Ward40407942005-03-05 02:53:17 +00001551- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1552 correctly.
1553
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001554- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1555 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1556 character even if the user has passed a size parameter to get a proper
1557 line ending. Remove the special handling of a "\r\n" that has been split
1558 between two lines.
1559
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001560- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1561 about illegal code points. The codec now supports PEP 293 style error
1562 handlers.
1563
Walter Dörwald78a78b02005-09-01 12:04:29 +00001564- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001565 from the input stream, so that the output is a byte string in the correct
1566 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001567
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001568- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1569 considering it exactly like a '*'.
1570
Walter Dörwald007f8df2005-10-09 19:42:27 +00001571- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1572 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001573
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001574- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1575
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001576- Patch #1413711: Certain patterns of differences were making difflib
1577 touch the recursion limit.
1578
Walter Dörwald58917a62006-03-31 15:26:22 +00001579- Bug #947906: An object oriented interface has been added to the calendar
1580 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001581 called as a script (e.g. via ``python -mcalendar``). Localized month and
1582 weekday names can be ouput (even if an exotic encoding is used) using
1583 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001584
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001585Build
1586-----
1587
Neal Norwitz602d3392006-03-31 08:21:40 +00001588- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1589 by using -mieee gcc option.
1590

1592
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001593- Build support for Win64-AMD64 was added.
1594
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001595- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1596
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001597- Patch #881820: look for openpty and forkpty also in libbsd.
1598
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001599- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1600 The zlib module is now builtin on Windows.
1601
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001602- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1603
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001604- Bug #1189330: configure did not correctly determine the necessary
1605 value of LINKCC if python was built with GCC 4.0.
1606
Trent Mick8321b422005-07-26 02:29:21 +00001607- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1608 vulnerability in zlib 1.2.1 and 1.2.2.
1609
Brett Cannon08cd5982005-04-24 22:26:38 +00001610- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1611 flags that change binary compatibility. Changes were also made to
1612 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001613 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001614
Bob Ippolitoed233462005-03-29 13:47:59 +00001615- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1616 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1617 no longer exists). This configure patch makes things right.
1618
Martin v. Löwise2713be2005-03-08 15:03:08 +00001619- Bug #1158607: Build with --disable-unicode again.
1620
Brett Cannon46d96232005-02-16 00:07:19 +00001621- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1622 defined. Discovered as a result of not being able to build on OS X.
1623
Brett Cannon516592f2004-12-07 00:42:59 +00001624- setup.py now uses the directories specified in LDFLAGS using the -L option
1625 and in CPPFLAGS using the -I option for adding library and include
1626 directories, respectively, for compiling extension modules against. This has
1627 led to the core being compiled using the values in CPPFLAGS. It also removes
1628 the need for the special-casing of both DarwinPorts and Fink for darwin since
1629 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1630 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1631 Fink, ``-I/opt/local/include`` for DarwinPorts).
1632
Brett Cannon43802422005-02-10 20:48:03 +00001633- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1634 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1635 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1636 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001638C API
1639-----
1640
Tim Petersc9d78aa2006-03-26 23:27:58 +00001641- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1642 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1643 is obtained via the ``PyObject_`` family, it must be released via the
1644 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1645 always been officially true, but when Python's small-object allocator was
1646 introduced, an attempt was made to cater to a few extension modules
1647 discovered at the time that obtained memory via ``PyObject_New`` but
1648 released it via ``PyMem_DEL``. It's years later, and if such code still
1649 exists it will fail now (probably with segfaults, but calling wrong
1650 low-level memory management functions can yield many symptoms).
1651
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001652- Added a C API for set and frozenset objects.
1653
Raymond Hettinger66517482004-12-03 11:45:13 +00001654- Removed PyRange_New().
1655
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001656- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1657 mapping argument now. This string is used as a mapping table. Byte values
1658 greater than the length of the string and 0xFFFE are treated as undefined
1659 mappings.
