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

19 and atof().
20
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000021- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
22 omit a default "error" argument for NULL pointer. This allows
23 the parser to take a codec from cjkcodecs again.

26-------
27
Thomas Woutersadd19112006-07-05 11:03:49 +000028- string.Template() now correctly handles tuple-values. Previously,
29 multi-value tuples would raise an exception and single-value tuples would
30 be treated as the value they contain, instead.
31
Martin v. Löwisede77f52006-07-03 13:01:35 +000032- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
33 even if some data are received.
34
Martin v. Löwis45482392006-07-03 12:28:58 +000035- Bug #1267547: Put proper recursive setup.py call into the
36 spec file generated by bdist_rpm.
37

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

79
Martin v. Löwisee1e06d2006-07-02 18:44:00 +000080- Bug #1513646: os.access on Windows now correctly determines write
81 access, again.
82
Neal Norwitz0f8b31a2006-06-28 06:28:31 +000083- Bug #1512695: cPickle.loads could crash if it was interrupted with
84 a KeyboardInterrupt.
85
Neal Norwitza12aa882006-07-06 06:45:08 +000086- Bug #1296433: parsing XML with a non-default encoding and
87 a CharacterDataHandler could crash the interpreter in pyexpat.
88
Neal Norwitz3b6b8012006-06-27 04:12:58 +000089Build
90-----
91
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +000092- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000115
Anthony Baxterd1136802006-06-19 12:04:15 +0000116*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000117
118Core and builtins
119-----------------
120
Georg Brandla56b9152006-06-19 06:35:54 +0000121- Patch #1507676: Error messages returned by invalid abstract object operations
122 (such as iterating over an integer) have been improved and now include the
123 type of the offending object to help with debugging.
124
Brett Cannonea3912b2006-06-13 21:46:41 +0000125- Bug #992017: A classic class that defined a __coerce__() method that returned
126 its arguments swapped would infinitely recurse and segfault the interpreter.
127
Neal Norwitz909eb122006-06-12 02:13:21 +0000128- Fix the socket tests so they can be run concurrently.
129
Neal Norwitzb9845e72006-06-12 02:11:18 +0000130- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000131 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000132
Brett Cannon22565aa2006-06-09 22:31:23 +0000133- Bug #532646: object.__call__() will continue looking for the __call__
134 attribute on objects until one without one is found. This leads to recursion
135 when you take a class and set its __call__ attribute to an instance of the
136 class. Originally fixed for classic classes, but this fix is for new-style.
137 Removes the infinite_rec_3 crasher.
138
Georg Brandl24250812006-06-09 18:45:48 +0000139- The string and unicode methods startswith() and endswith() now accept
140 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
141
Brett Cannonde3b0522006-06-08 17:00:45 +0000142- Buffer objects, at the C level, never used the char buffer
143 implementation even when the char buffer for the wrapped object was
144 explicitly requested (originally returned the read or write buffer).
145 Now a TypeError is raised if the char buffer is not present but is
146 requested.
147
Georg Brandlddbaa662006-06-04 21:56:52 +0000148- Patch #1346214: Statements like "if 0: suite" are now again optimized
149 away like they were in Python 2.4.
150
Georg Brandlb7c8f542006-05-27 12:30:25 +0000151- Builtin exceptions are now full-blown new-style classes instead of
152 instances pretending to be classes, which speeds up exception handling
153 by about 80% in comparison to 2.5a2.
154
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000155- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
156 Unicode 4.1.
157
Georg Brandlf4ef1162006-05-26 18:03:31 +0000158- Patch #921466: sys.path_importer_cache is now used to cache valid and
159 invalid file paths for the built-in import machinery which leads to
160 fewer open calls on startup.
161
Tim Peters696cf432006-05-24 21:10:40 +0000162- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
163 of-2 bases. The largest speedup is for inputs with about 1000 decimal
164 digits. Conversion from non-power-of-2 bases remains quadratic-time in
165 the number of input digits (it was and remains linear-time for bases
166 2, 4, 8, 16 and 32).
167
Tim Petersb713ec22006-05-23 18:45:30 +0000168- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
169 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
170 an integer close to ``sys.maxint``. This was repaired by patch
171 #1335972, which also gives a nice speedup.
172
Richard Jonescebbefc2006-05-23 18:28:17 +0000173- Patch #1337051: reduced size of frame objects.
174
175- PyErr_NewException now accepts a tuple of base classes as its
176 "base" parameter.
177
Richard Jones7c88dcc2006-05-23 10:37:38 +0000178- Patch #876206: function call speedup by retaining allocated frame
179 objects.
180
Georg Brandl7b90e162006-05-18 07:01:27 +0000181- Bug #1462152: file() now checks more thoroughly for invalid mode
182 strings and removes a possible "U" before passing the mode to the
183 C library function.
184
Neal Norwitz1004a532006-05-15 07:17:23 +0000185- Patch #1488312, Fix memory alignment problem on SPARC in unicode
186
Neal Norwitz373f0a72006-05-15 07:04:36 +0000187- Bug #1487966: Fix SystemError with conditional expression in assignment
188
Martin v. Löwis879768d2006-05-11 13:28:43 +0000189- WindowsError now has two error code attributes: errno, which carries
190 the error values from errno.h, and winerror, which carries the error
191 values from winerror.h. Previous versions put the winerror.h values
192 (from GetLastError()) into the errno attribute.
193
Martin v. Löwis77736712006-05-04 05:51:03 +0000194- Patch #1475845: Raise IndentationError for unexpected indent.
195
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000196- Patch #1479181: split open() and file() from being aliases for each other.
197
Tim Peters44bd9862006-06-01 13:49:23 +0000198- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
199 methods were always silently ignored by dictionaries when comparing keys.
200 They are now passed through (except when using the C API function
201 ``PyDict_GetItem()``, whose semantics did not change).
202
203- Bug #1456209: In some obscure cases it was possible for a class with a
204 custom ``__eq__()`` method to confuse dict internals when class instances
205 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
206 No, you don't have any code that did this ;-)

214
Brett Cannon6ee7d012006-06-08 16:23:04 +0000215- Change binascii.hexlify to accept a read-only buffer instead of only a char
216 buffer and actually follow its documentation.
217
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000218- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
219
Nick Coghlanc649ec52006-05-29 12:43:05 +0000220- Patch #1478788 (modified version): The functional extension module has
221 been renamed to _functools and a functools Python wrapper module added.
222 This provides a home for additional function related utilities that are
223 not specifically about functional programming. See PEP 309.
224
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000225- Patch #1493701: performance enhancements for struct module.

230 copy() method.
231
Andrew MacIntyre92913322006-06-13 15:04:24 +0000232- Patch #1454481: thread stack size is now tunable at runtime for thread
233 enabled builds on Windows and systems with Posix threads support.
234
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000235- On Win32, os.listdir now supports arbitrarily-long Unicode path names
236 (up to the system limit of 32K characters).
237
238- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
239 As a result, these functions now raise WindowsError instead of OSError.
240
Tim Peters7a822da2006-05-25 21:50:17 +0000241- ``time.clock()`` on Win64 should use the high-performance Windows
242 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
243 Windows platforms).
244
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000245- Calling Tk_Init twice is refused if the first call failed as that
246 may deadlock.
247
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000248- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
249 accept it without potentially using an uninitialized pointer.
250
251- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
252 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
253 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000254
Gregory P. Smith372b5832006-06-05 18:48:21 +0000255- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000256 [pybsddb project SF patch number 1466734]
257
Gregory P. Smith372b5832006-06-05 18:48:21 +0000258- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
259 parameter is supplied. [SF pybsddb bug #1477863]
260
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000261- bsddb: the __len__ method of a DB object has been fixed to return correct
262 results. It could previously incorrectly return 0 in some cases.
263 Fixes SF bug 1493322 (pybsddb bug 1184012).
264
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000265- bsddb: the bsddb.dbtables Modify method now raises the proper error and
266 aborts the db transaction safely when a modifier callback fails.
267 Fixes SF python patch/bug #1408584.
268
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000269- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000270 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000271 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
272 database calls that would previously deadlock. [SF python bug #775414]
273
Vinay Sajip28e57612006-07-01 10:45:20 +0000274- Patch #1446489: add support for the ZIP64 extensions to zipfile.

303
Tim Peters43898b42006-06-14 04:09:25 +0000304- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
305 guarantee that adjacent triples in the return list always describe
306 non-adjacent blocks. Previously, a pair of matching blocks could end
307 up being described by multiple adjacent triples that formed a partition
308 of the matching pair.

Greg Wardd1c797e2006-06-11 14:42:41 +0000313- Bug #1366250: minor optparse documentation error.
314
Greg Ward7f547402006-06-11 00:40:49 +0000315- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
316 clarify docs.
317
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000318- The wsgiref package has been added to the standard library.
319
Nick Coghlan676725d2006-06-08 13:54:49 +0000320- The functions update_wrapper() and wraps() have been added to the functools
321 module. These make it easier to copy relevant metadata from the original
322 function when writing wrapper functions.
323
Tim Petersd6a9eef2006-06-05 01:48:21 +0000324- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
325 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000326
Martin v. Löwis3f767792006-06-04 19:36:28 +0000327- Patch #1359618: Speed up charmap encoder by using a trie structure
328 for lookup.
329
Tim Petersd609b1a2006-06-02 23:22:51 +0000330- The functions in the ``pprint`` module now sort dictionaries by key
331 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
332 if and only if its display required more than one line, although that
333 wasn't documented. The new behavior increases predictability; e.g.,
334 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
335
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000336- Patch #1497027: try HTTP digest auth before basic auth in urllib2
337 (thanks for J. J. Lee).
338
Georg Brandl2b330372006-05-28 20:23:12 +0000339- Patch #1496206: improve urllib2 handling of passwords with respect to
340 default HTTP and HTTPS ports.
341
George Yoshidaf3c65de2006-05-28 16:39:09 +0000342- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
343
Bob Ippolito7298f272006-05-23 18:43:47 +0000344- Patch #1281707: speed up gzip.readline.
345
Georg Brandlb89316f2006-05-17 15:51:16 +0000346- Patch #1180296: Two new functions were added to the locale module:
347 format_string() to get the effect of "format % items" but locale-aware,
348 and currency() to format a monetary number with currency sign.
349
Georg Brandle3a25832006-05-17 14:56:04 +0000350- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
351 and several features added, such as speed and geometry control.
352
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000353- Patch #1488881: add support for external file objects in bz2 compressed
354 tarfiles.
355
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000356- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
357 stdout arguments, making it possible to redirect input and output
358 for remote debugging.
359
360- Patch #1484695: Update the tarfile module to version 0.8. This fixes
361 a couple of issues, notably handling of long file names using the
362 GNU LONGNAME extension.
363
364- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
365 new flag when ``name`` is already the name of an option flag.
366
367- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
368 package.
369
370- Patch #1472854: make the rlcompleter.Completer class usable on non-
371 UNIX platforms.
372
373- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
374
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000375- Bug #1472827: correctly escape newlines and tabs in attribute values in
376 the saxutils.XMLGenerator class.

Georg Brandl66a0dbb2006-06-08 12:54:13 +0000382- Bug #1502728: Correctly link against librt library on HP-UX.
383
Martin v. Löwis222c5152006-06-03 07:37:13 +0000384- OpenBSD 3.9 is supported now.
385
Martin v. Löwisa43190b2006-05-22 09:15:18 +0000386- Patch #1492356: Port to Windows CE.
387
Neal Norwitz58e28882006-05-19 07:00:58 +0000388- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
389
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000390- Patch #1471883: Add --enable-universalsdk.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000406What's New in Python 2.5 alpha 2?
407=================================
408
409*Release date: 27-APR-2006*
410
411Core and builtins
412-----------------
413
Thomas Heller1b046642006-04-18 18:51:06 +0000414- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
415 by converting these apis from macros into exported functions again:
416
417 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
418 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
419 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
420 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
421 PyRun_String Py_CompileString
422
Martin v. Löwis45294a92006-04-18 06:24:08 +0000423- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
424
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000425- All uses of PyStructSequence_InitType have been changed to initialize
426 the type objects only once, even if the interpreter is initialized
427 multiple times.
428
Neal Norwitz61546162006-04-14 05:20:28 +0000429- Bug #1454485, array.array('u') could crash the interpreter. This was
430 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
431 to unicode when it didn't make sense. 'u#' now requires a unicode string.
432
433- Py_UNICODE is unsigned. It was always documented as unsigned, but
434 due to a bug had a signed value in previous versions.
435
Tim Peters3a5e8b12006-04-11 01:44:07 +0000436- Patch #837242: ``id()`` of any Python object always gives a positive
437 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
438 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000439 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000440 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000441
Tim Peters3a5e8b12006-04-11 01:44:07 +0000442 def __hash__(self):
443 return id(self) # WRONG
444
445 because a hash result must be a (short) Python int but it was always
446 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000447 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000448 was always usable as a hash value before this patch. That's no longer
449 necessarily so.
450
451- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000452 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000453 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000454 #1454844)
455
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000456- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
457 involving generators that have paused outside of any ``try`` or ``with``
458 blocks. (In 2.5a1, a paused generator that was part of a reference
459 cycle could not be garbage collected, regardless of whether it was
460 paused in a ``try`` or ``with`` block.)

466 is a macro.
467
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000468- Bug #1467952: os.listdir() now correctly raises an error if readdir()
469 fails with an error condition.
470
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000471- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
472
473- Bug #1117761: bsddb.*open() no longer raises an exception when using
474 the cachesize parameter.
475
476- Bug #1149413: bsddb.*open() no longer raises an exception when using
477 a temporary db (file=None) with the 'n' flag to truncate on open.
478
479- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
480 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000481
Armin Rigoa9017c32006-04-19 11:50:27 +0000482- Patch #1062014: AF_UNIX sockets under Linux have a special
483 abstract namespace that is now fully supported.
484
Anthony Baxter51bcb682006-04-05 14:51:42 +0000485Library
486-------
487
Tim Peters711bf302006-04-25 03:31:36 +0000488- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
489 a doctest to be skipped (the code is not run, and the expected output
490 or exception is ignored).
491
Nick Coghlanda2268f2006-04-24 04:37:15 +0000492- Fixed contextlib.nested to cope with exceptions being raised and
493 caught inside exit handlers.
494
Greg Wardab05edc2006-04-23 03:47:58 +0000495- Updated optparse module to Optik 1.5.1 (allow numeric constants in
496 hex, octal, or binary; add ``append_const`` action; keep going if
497 gettext cannot be imported; added ``OptionParser.destroy()`` method;
498 added ``epilog`` for better help generation).
499
Tim Peters21fbd572006-04-21 21:18:10 +0000500- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
501 called from a thread spawned as a side effect of importing a module.
502
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000503- The pydoc module now supports documenting packages contained in
504 .zip or .egg files.
505
506- The pkgutil module now has several new utility functions, such
507 as ``walk_packages()`` to support working with packages that are either
508 in the filesystem or zip files.
509
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000510- The mailbox module can now modify and delete messages from
511 mailboxes, in addition to simply reading them. Thanks to Gregory
512 K. Johnson for writing the code, and to the 2005 Google Summer of
513 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000514
Tim Petersc7605f22006-04-17 21:12:33 +0000515- The ``__del__`` method of class ``local`` in module ``_threading_local``
516 returned before accomplishing any of its intended cleanup.
517
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000518- Patch #790710: Add breakpoint command lists in pdb.
519
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000520- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000522- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
523
Anthony Baxtere29002c2006-04-12 12:07:31 +0000524- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
525 Windows. Bug #1469163.
526
Phillip J. Eby47032112006-04-11 01:07:43 +0000527- The warnings, linecache, inspect, traceback, site, and doctest modules
528 were updated to work correctly with modules imported from zipfiles or
529 via other PEP 302 __loader__ objects.
530
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000531- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000551- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
552 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000553 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000554 CXX from --with-cxx-main, see description in README.
555
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000556- Patch #1429775: Link extension modules with the shared libpython.

Tim Peters8931ff12006-05-13 23:28:20 +0000560- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
561 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

563
Anthony Baxter51bcb682006-04-05 14:51:42 +0000564Tests

571
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000572- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
573 it separately and by hand. It also wasn't cleaning up its changes to
574 the current Decimal context.
575
Thomas Woutersabd08882006-04-26 15:53:30 +0000576- regrtest.py now has a -M option to run tests that test the new limits of
577 containers, on 64-bit architectures. Running these tests is only sensible
578 on 64-bit machines with more than two gigabytes of memory. The argument
579 passed is the maximum amount of memory for the tests to use.

591
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000592- PEP 343: Added Context Types section to the library reference
593 and attempted to bring other PEP 343 related documentation into
594 line with the implementation and/or python-dev discussions.
595
Tim Peters8dc73d22006-04-24 02:03:16 +0000596- Bug #1337990: clarified that ``doctest`` does not support examples

Nick Coghlan43832302006-04-23 17:04:07 +0000608- PEP 338: -m command line switch now delegates to runpy.run_module
609 allowing it to support modules in packages and zipfiles
610
Martin v. Löwisc661b882006-04-20 04:54:23 +0000611- On Windows, .DLL is not an accepted file name extension for
612 extension modules anymore; extensions are only found if they
613 end in .PYD.
614
Martin v. Löwisea62d252006-04-03 10:56:49 +0000615- Bug #1421664: sys.stderr.encoding is now set to the same value as
616 sys.stdout.encoding.
617
Neal Norwitz92e212f2006-04-03 04:48:37 +0000618- __import__ accepts keyword arguments.

Neal Norwitze98ccf62006-03-23 05:39:47 +0000627- Bug #1115379: Compiling a Unicode string with an encoding declaration
628 now gives a SyntaxError.
629
Georg Brandlabd1ff82006-03-18 07:59:59 +0000630- Previously, Python code had no easy way to access the contents of a
631 cell object. Now, a ``cell_contents`` attribute has been added
632 (closes patch #1170323).
633
Tim Peterscf79aac2006-03-16 01:14:46 +0000634- Patch #1123430: Python's small-object allocator now returns an arena to
635 the system ``free()`` when all memory within an arena becomes unused
636 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
637 freed. Some applications will see a drop in virtual memory size now,
638 especially long-running applications that, from time to time, temporarily
639 use a large number of small objects. Note that when Python returns an
640 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000641 platform C library will in turn return that memory to the operating system.
642 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000643 appears to be effective at least on Microsoft C and gcc-based systems.
644 Thanks to Evan Jones for hard work and patience.
645
Georg Brandl533ff6f2006-03-08 18:09:27 +0000646- Patch #1434038: property() now uses the getter's docstring if there is
647 no "doc" argument given. This makes it possible to legitimately use
648 property() as a decorator to produce a read-only property.
649
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000650- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
651 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
652 of requiring an int or long in slicing and a few other contexts, enabling
653 other objects (e.g. Numeric Python's integers) to be used as slice indices.
654
Neal Norwitz995acdf2006-03-07 05:01:00 +0000655- Fixed various bugs reported by Coverity's Prevent tool.
656
Brett Cannonbf364092006-03-01 04:25:17 +0000657- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
658 new exception base class, BaseException, which has a new message attribute.
659 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
660 Raising a string exception now raises a DeprecationWarning.
661
Thomas Woutersfb609f42006-02-28 16:37:25 +0000662- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
663 explicitly relative, using 'from .module import name' to mean 'from the same
664 package as this module is in. Imports without dots still default to the
665 old relative-then-absolute, unless 'from __future__ import
666 absolute_import' is used.
667
Brett Cannona7446e32006-02-27 23:39:10 +0000668- Properly check if 'warnings' raises an exception (usually when a filter set
669 to "error" is triggered) when raising a warning for raising string
670 exceptions.
671
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000672- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000673 The name was removed from Include/code.h.
674
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000675- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000676
Guido van Rossum1968ad32006-02-25 22:38:04 +0000677- Patch 1433928:
678 - The copy module now "copies" function objects (as atomic objects).
679 - dict.__getitem__ now looks for a __missing__ hook before raising
680 KeyError.
681
Tim Peters84ef21c2006-02-28 20:39:06 +0000682- PEP 343: with statement implemented. Needs ``from __future__ import
683 with_statement``. Use of 'with' as a variable will generate a warning.
684 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000685 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000686 The following objects have __context__ methods:
687 - The built-in file type.
688 - The thread.LockType type.
689 - The following types defined by the threading module:
690 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
691 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000692
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000693- Fix the encodings package codec search function to only search
694 inside its own package. Fixes problem reported in patch #1433198.
695
696 Note: Codec packages should implement and register their own
697 codec search function. PEP 100 has the details.
698
Tim Peters9ea89d22006-06-04 03:26:02 +0000699- PEP 353: Using ``Py_ssize_t`` as the index type.
700
701- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
702 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
703 now allow Python to make use of memory blocks exceeding 2**32 bytes for
704 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
705 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000706
Neal Norwitzfc76d632006-01-10 06:03:13 +0000707- Patch #1400181, fix unicode string formatting to not use the locale.
708 This is how string objects work. u'%f' could use , instead of .
709 for the decimal point. Now both strings and unicode always use periods.
710
Neal Norwitz671b9e32006-01-09 07:07:12 +0000711- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
712 configure would break checking curses.h.
713
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000714- Bug #959576: The pwd module is now builtin. This allows Python to be
715 built on UNIX platforms without $HOME set.
716
Neal Norwitzc10978f2005-12-19 06:07:16 +0000717- Bug #1072182, fix some potential problems if characters are signed.
718
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000719- Bug #889500, fix line number on SyntaxWarning for global declarations.
720
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000721- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
722
Neal Norwitze7214a12005-12-18 05:03:17 +0000723- Support for converting hex strings to floats no longer works.
724 This was not portable. float('0x3') now raises a ValueError.
725
Barry Warsaw2a38a862005-12-18 01:27:35 +0000726- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000727 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000728 is now displayed in interactive prompt banner.
729
Georg Brandlfa166682005-12-17 21:45:17 +0000730- Implementation of PEP 341 - Unification of try/except and try/finally.
731 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000732 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000733
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000734- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
735 now encodes backslash correctly.
736
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000737- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
738
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000739- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000740 and long longs.
741
Neal Norwitz67715f02005-11-09 06:59:35 +0000742- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000743 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000744 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000745
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000746- Replaced most Unicode charmap codecs with new ones using the
747 new Unicode translate string feature in the builtin charmap
748 codec; the codecs were created from the mapping tables available
749 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
750 encodings now include a mapping for the Apple logo)
751
Tim Peterse3547fd2005-12-16 23:13:57 +0000752- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000753
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000754- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000755
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000756- A new AST parser implementation was completed. The abstract
757 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000758 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000759
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000760- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000761 The following code now raises a SyntaxError: foo(a = i for i in range(10))
762
Neal Norwitz708e51a2005-10-03 04:48:15 +0000763- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
764
Neal Norwitz11bd1192005-10-03 00:54:56 +0000765- SF Bug #887946: fix segfault when redirecting stdin from a directory.
766 Provide a warning when a directory is passed on the command line.
767
Neal Norwitz40d37812005-10-02 01:48:49 +0000768- Fix segfault with invalid coding.
769
770- SF bug #772896: unknown encoding results in MemoryError.
771
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000772- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000773 supported a __len__() method which evaluated to False when the iterator
774 was empty.
775
Guido van Rossum630db602005-09-20 18:49:54 +0000776- On 64-bit platforms, when __len__() returns a value that cannot be
777 represented as a C int, raise OverflowError.
778
Skip Montanarof8948ca2005-09-19 03:54:46 +0000779- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000780 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000781
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000782- SF bug #893549: parsing keyword arguments was broken with a few format
783 codes.
784
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000785- Changes donated by Elemental Security to make it work on AIX 5.3
786 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
787 bug #105470: test_pwd fails on 64bit system (Opteron).
788
Guido van Rossum539c6622005-09-14 17:49:54 +0000789- Changes donated by Elemental Security to make it work on HP-UX 11 on
790 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
791
Georg Brandl4550b8d2005-08-26 06:43:52 +0000792- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000793 (fixes bug #1119418).
794
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000795- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
796
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000797- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
798 exceptions that cause a function to exit.
799
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000800- The implementation of set() and frozenset() was revised to use its
801 own internal data structure. Memory consumption is reduced by 1/3
802 and there are modest speed-ups as well. The API is unchanged.
803
Tim Petersde7990b2005-07-17 23:45:23 +0000804- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
805
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000806- SF bug #1229429: PyObject_CallMethod failed to decrement some
807 reference counts in some error exit cases.
808
Tim Petersecc6e6a2005-07-10 22:30:55 +0000809- SF bug #1185883: Python's small-object memory allocator took over
810 a block managed by the platform C library whenever a realloc specified
811 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000812 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000813 portable way to copy data from the C-managed block into Python's
814 small-object space without risking a memory fault. Python's small-object
815 realloc now leaves such blocks under the control of the platform C
816 realloc.
817
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000818- SF bug #1232517: An overflow error was not detected properly when
819 attempting to convert a large float to an int in os.utime().
820
Raymond Hettinger3296e692005-06-29 23:29:56 +0000821- SF bug #1224347: hex longs now print with lowercase letters just
822 like their int counterparts.
823
Michael W. Hudson188d4362005-06-20 16:52:57 +0000824- SF bug #1163563: the original fix for bug #1010677 ("thread Module
825 Breaks PyGILState_Ensure()") broke badly in the case of multiple
826 interpreter states; back out that fix and do a better job (see
827 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
828 for a longer write-up of the problem).
829
Michael W. Hudsondf888462005-06-03 14:41:55 +0000830- SF patch #1180995: marshal now uses a binary format by default when
831 serializing floats.
832
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000833- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
834 the routines that promise to produce IEEE 754 binary representations
835 of floats now simply copy bytes around.
836
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000837- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
838 278.
839
Brett Cannonc3647ac2005-04-26 03:45:26 +0000840- patch #1109424: int, long, float, complex, and unicode now check for the
841 proper magic slot for type conversions when subclassed. Previously the
842 magic slot was ignored during conversion. Semantics now match the way
843 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000844 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000845 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000846 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000847
Barry Warsawc8d907c2005-04-19 23:43:40 +0000848- Descriptors defined in C with a PyGetSetDef structure, where the setter is
849 NULL, now raise an AttributeError when attempting to set or delete the
850 attribute. Previously a TypeError was raised, but this was inconsistent
851 with the equivalent pure-Python implementation.
852
Michael W. Hudson774479c2005-04-18 08:46:17 +0000853- It is now safe to call PyGILState_Release() before
854 PyEval_InitThreads() (note that if there is reason to believe there
855 are multiple threads around you still must call PyEval_InitThreads()
856 before using the Python API; this fix is for extension modules that
857 have no way of knowing if Python is multi-threaded yet).
858
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000859- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
860 disabled caused a crash.
861
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000862- Bug #1165306: instancemethod_new allowed the creation of a method
863 with im_class == im_self == NULL, which caused a crash when called.
864
Tim Petersecc6e6a2005-07-10 22:30:55 +0000865- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000866 fixes the crash seen in bug #1165761
867
Raymond Hettinger96229b12005-03-11 06:49:40 +0000868- Added two new builtins, any() and all().
869
Brett Cannon409d8f22005-03-05 06:47:57 +0000870- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000871 (e.g., ``class C(): pass`` is no longer a syntax error).
872 Patch #1176012 added support to the 'parser' module and 'compiler' package
873 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000874
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000875- Patch #1115086: Support PY_LONGLONG in structmember.
876
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000877- Bug #1155938: new style classes did not check that __init__() was
878 returning None.
879
Tim Petersecc6e6a2005-07-10 22:30:55 +0000880- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000881 ('\') with a specific error message.
882
Martin v. Löwisff232d72005-03-03 09:24:38 +0000883- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
884
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000885- Bug #1124295: the __name__ attribute of file objects was
886 inadvertently made inaccessible in restricted mode.
887
Tim Petersecc6e6a2005-07-10 22:30:55 +0000888- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000889 an ferror() call.
890
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000891- min() and max() now support key= arguments with the same meaning as in
892 list.sort().
893
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000894- The peephole optimizer now performs simple constant folding in expressions:
895 (2+3) --> (5).
896
Raymond Hettingera422c342005-01-11 03:03:27 +0000897- set and frozenset objects can now be marshalled. SF #1098985.
898
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000899- Bug #1077106: Poor argument checking could cause memory corruption
900 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000901
Jeremy Hyltonab630502005-02-04 18:44:06 +0000902- The parser did not complain about future statements in illegal
903 positions. It once again reports a syntax error if a future
904 statement occurs after anything other than a doc string.
905
Neil Schemenauercf52c072005-08-12 17:34:58 +0000906- Change the %s format specifier for str objects so that it returns a
907 unicode instance if the argument is not an instance of basestring and
908 calling __str__ on the argument returns a unicode instance.
909
Tim Petersf4e69282006-02-27 17:15:31 +0000910- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
911 current thread state when the auto-GIL-state machinery knows about
912 it (since the thread state is being deleted, continuing to remember it
913 can't help, but can hurt if another thread happens to get created with
914 the same thread id).

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001046- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1047 the request code argument, which results in more C-like behaviour
1048 for large or negative values.

1095 islice(s.start, s.stop, s.step)
1096
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001097- datetime.datetime() now has a strptime class method which can be used to

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001103Library
1104-------
1105
Nick Coghlan43832302006-04-23 17:04:07 +00001106- PEP 338: new module runpy defines a run_module function to support
1107 executing modules which provide access to source code or a code object
1108 via the PEP 302 import mechanisms.
1109
Anthony Baxter93f5b932006-04-03 08:05:07 +00001110- The email module's parsedate_tz function now sets the daylight savings
1111 flag to -1 (unknown) since it can't tell from the date whether it should
1112 be set.
1113
Fred Drakead5177c2006-04-01 22:14:43 +00001114- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
1115 now sport attributes that provide access to the parts of the result.
1116

1118 in attribute values.
1119
Anthony Baxterc51ee692006-04-01 00:57:31 +00001120- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001121 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001122 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001123 module will not be built.
1124
Tim Petersc17976e2006-04-01 00:26:53 +00001125- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1126 aren't officially supported here, and trying to use them will probably
1127 raise an exception some day. But dicts have been allowed, and "mostly
1128 worked", so support for them won't go away without warning.
1129
Georg Brandl338ef7d2006-03-31 18:42:16 +00001130- Bug #1445068: getpass.getpass() can now be given an explicit stream
1131 argument to specify where to write the prompt.
1132
Georg Brandl22ec80b2006-03-31 18:25:44 +00001133- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1148
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001149- email 4.0 package now integrated. This is largely the same as the email 3.0
1150 package that was included in Python 2.3, except that PEP 8 module names are
1151 now used (e.g. mail.message instead of email.Message). The MIME classes
1152 have been moved to a subpackage (e.g. email.mime.text instead of
1153 email.MIMEText). The old names are still supported for now. Several
1154 deprecated Message methods have been removed and lots of bugs have been
1155 fixed. More details can be found in the email package documentation.
1156
Walter Dörwald40108c92006-03-27 08:15:44 +00001157- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1158 (a subclass of tuple) that provides incremental decoders and encoders
1159 (a way to use stateful codecs without the stream API). Python functions
1160 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1161 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1162 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001163
Walter Dörwald067db482006-03-15 22:17:27 +00001164- Patch #1359365: Calling next() on a closed StringIO.String object raises
1165 a ValueError instead of a StopIteration now (like file and cString.String do).
1166 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1167 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001168
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001169- A regrtest option -w was added to re-run failed tests in verbose mode.

1172 interpreter to exit.
1173
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001174- The function get_count() has been added to the gc module, and gc.collect()
1175 grew an optional 'generation' argument.

1246 "The consensus of researchers in this area (at least as
1247 expressed at the NIST Hash Function Workshop 10/31/05),
1248 is that SHA-256 is a good choice for the time being, but
1249 that research should continue, and other alternatives may
1250 arise from this research. The larger SHA's also seem OK."

Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001433 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001434 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001435 + Dialect parameter parsing has been re-implemented to improve error
1436 reporting.
1437 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1438 dictates.
1439 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001440 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001441 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001442 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1443 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001444 + reader now allows \r characters to be quoted (previously it only allowed
1445 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001446 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001447 + Dialect classes passed to the module are no longer instantiated by
1448 the module before being parsed (the former validation scheme required
1449 this, but the mechanism was unreliable).
1450 + The dialect registry now contains instances of the internal
1451 C-coded dialect type, rather than references to python objects.
1452 + the internal c-coded dialect type is now immutable.
1453 + register_dialect now accepts the same keyword dialect specifications
1454 as the reader and writer, allowing the user to register dialects
1455 without first creating a dialect class.
1456 + a configurable limit to the size of parsed fields has been added -
1457 previously, an unmatched quote character could result in the entire
1458 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001459 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001460 the parser field size limit (returning the former limit). The initial
1461 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001462 + A line_num attribute has been added to the reader object, which tracks
1463 the number of lines read from the source iterator. This is not
1464 the same as the number of records returned, as records can span
1465 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001466 + reader and writer objects were not being registered with the cyclic-GC.
1467 This has been fixed.
1468
Brett Cannone6539c42005-01-08 02:43:53 +00001469- _DummyThread objects in the threading module now delete self.__block that is
1470 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1471 lock primitives tend to be limited in number and thus should not be wasted on
1472 a _DummyThread object. Fixes bug #1089632.
1473
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001474- The imghdr module now detects Exif files.
1475
Raymond Hettinger6065d322004-12-20 23:51:53 +00001476- StringIO.truncate() now correctly adjusts the size attribute.
1477 (Bug #951915).
1478
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001479- locale.py now uses an updated locale alias table (built using
1480 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1481 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001482 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001483
Raymond Hettinger3557f422004-12-07 12:02:02 +00001484- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1485
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001486- the pickle module no longer accepts the deprecated None option in the
1487 args tuple returned by __reduce__().
1488
Brett Cannon84667c02004-12-07 03:25:18 +00001489- optparse now optionally imports gettext. This allows its use in setup.py.
1490
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001491- the pickle module no longer uses the deprecated bin parameter.
1492
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001493- the shelve module no longer uses the deprecated binary parameter.
1494
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001495- the pstats module no longer uses the deprecated ignore() method.
1496
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001497- the filecmp module no longer uses the deprecated use_statcache argument.
1498
Raymond Hettinger664347b2004-12-04 21:21:53 +00001499- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1500 extended or overridden by subclasses. Formerly, the subclassed method would
1501 be ignored by the rest of the module. (Bug #1078905).
1502
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001503- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001504 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001505
Walter Dörwald36733692004-12-22 12:50:50 +00001506- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1507 once when a size argument is given. This prevents a buffer overflow in the
1508 tokenizer with very long source lines.
1509
Barry Warsaw538561e2006-01-01 21:48:54 +00001510- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1511 immediately after creating the object, without any intervening
1512 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001513
Skip Montanaro05885812005-01-16 20:48:27 +00001514- The reconvert.quote function can now emit triple-quoted strings. The
1515 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001516
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001517- ``UserString.MutableString`` now supports negative indices in
1518 ``__setitem__`` and ``__delitem__``
1519
Greg Ward40407942005-03-05 02:53:17 +00001520- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1521 correctly.
1522
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001523- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1524 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1525 character even if the user has passed a size parameter to get a proper
1526 line ending. Remove the special handling of a "\r\n" that has been split
1527 between two lines.
1528
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001529- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1530 about illegal code points. The codec now supports PEP 293 style error
1531 handlers.
1532
Walter Dörwald78a78b02005-09-01 12:04:29 +00001533- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001534 from the input stream, so that the output is a byte string in the correct
1535 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001536
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001537- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1538 considering it exactly like a '*'.
1539
Walter Dörwald007f8df2005-10-09 19:42:27 +00001540- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1541 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001542
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001543- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1544
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001545- Patch #1413711: Certain patterns of differences were making difflib
1546 touch the recursion limit.
1547
Walter Dörwald58917a62006-03-31 15:26:22 +00001548- Bug #947906: An object oriented interface has been added to the calendar
1549 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001550 called as a script (e.g. via ``python -mcalendar``). Localized month and
1551 weekday names can be ouput (even if an exotic encoding is used) using
1552 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001553
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001554Build

1556
Neal Norwitz602d3392006-03-31 08:21:40 +00001557- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1558 by using -mieee gcc option.
1559
Martin v. Löwis86d66262006-02-17 08:40:11 +00001560- Patch #1432345: Make python compile on DragonFly.
1561
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001562- Build support for Win64-AMD64 was added.
1563
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001564- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1565
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001566- Patch #881820: look for openpty and forkpty also in libbsd.
1567
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001568- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1569 The zlib module is now builtin on Windows.
1570
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001571- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1572
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001573- Bug #1189330: configure did not correctly determine the necessary
1574 value of LINKCC if python was built with GCC 4.0.
1575
Trent Mick8321b422005-07-26 02:29:21 +00001576- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1577 vulnerability in zlib 1.2.1 and 1.2.2.
1578
Brett Cannon08cd5982005-04-24 22:26:38 +00001579- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1580 flags that change binary compatibility. Changes were also made to
1581 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001582 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001583
Bob Ippolitoed233462005-03-29 13:47:59 +00001584- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1585 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1586 no longer exists). This configure patch makes things right.
1587
Martin v. Löwise2713be2005-03-08 15:03:08 +00001588- Bug #1158607: Build with --disable-unicode again.
1589
Brett Cannon46d96232005-02-16 00:07:19 +00001590- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1591 defined. Discovered as a result of not being able to build on OS X.
1592
Brett Cannon516592f2004-12-07 00:42:59 +00001593- setup.py now uses the directories specified in LDFLAGS using the -L option
1594 and in CPPFLAGS using the -I option for adding library and include
1595 directories, respectively, for compiling extension modules against. This has
1596 led to the core being compiled using the values in CPPFLAGS. It also removes
1597 the need for the special-casing of both DarwinPorts and Fink for darwin since
1598 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1599 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1600 Fink, ``-I/opt/local/include`` for DarwinPorts).
1601
Brett Cannon43802422005-02-10 20:48:03 +00001602- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1603 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1604 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1605 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001607C API
1608-----
1609
Tim Petersc9d78aa2006-03-26 23:27:58 +00001610- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1611 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1612 is obtained via the ``PyObject_`` family, it must be released via the
1613 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1614 always been officially true, but when Python's small-object allocator was
1615 introduced, an attempt was made to cater to a few extension modules
1616 discovered at the time that obtained memory via ``PyObject_New`` but
1617 released it via ``PyMem_DEL``. It's years later, and if such code still
1618 exists it will fail now (probably with segfaults, but calling wrong
1619 low-level memory management functions can yield many symptoms).
1620
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001621- Added a C API for set and frozenset objects.
1622
Raymond Hettinger66517482004-12-03 11:45:13 +00001623- Removed PyRange_New().
1624
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001625- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1626 mapping argument now. This string is used as a mapping table. Byte values
1627 greater than the length of the string and 0xFFFE are treated as undefined
1628 mappings.
