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

22 omit a default "error" argument for NULL pointer. This allows
23 the parser to take a codec from cjkcodecs again.

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

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

78-----------------
79
Martin v. Löwisee1e06d2006-07-02 18:44:00 +000080- Bug #1513646: os.access on Windows now correctly determines write
81 access, again.
82
Neal Norwitz0f8b31a2006-06-28 06:28:31 +000083- Bug #1512695: cPickle.loads could crash if it was interrupted with
84 a KeyboardInterrupt.

Neal Norwitzb15ac312006-06-29 04:10:08 +000092Tests
93-----
94
95- Call os.waitpid() at the end of tests that spawn child processes in order
96 to minimize resources (zombies).

109Core and builtins
110-----------------
111
Georg Brandla56b9152006-06-19 06:35:54 +0000112- Patch #1507676: Error messages returned by invalid abstract object operations
113 (such as iterating over an integer) have been improved and now include the
114 type of the offending object to help with debugging.
115
Brett Cannonea3912b2006-06-13 21:46:41 +0000116- Bug #992017: A classic class that defined a __coerce__() method that returned
117 its arguments swapped would infinitely recurse and segfault the interpreter.
118
Neal Norwitz909eb122006-06-12 02:13:21 +0000119- Fix the socket tests so they can be run concurrently.
120
Neal Norwitzb9845e72006-06-12 02:11:18 +0000121- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000122 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000123
Brett Cannon22565aa2006-06-09 22:31:23 +0000124- Bug #532646: object.__call__() will continue looking for the __call__
125 attribute on objects until one without one is found. This leads to recursion
126 when you take a class and set its __call__ attribute to an instance of the
127 class. Originally fixed for classic classes, but this fix is for new-style.
128 Removes the infinite_rec_3 crasher.
129
Georg Brandl24250812006-06-09 18:45:48 +0000130- The string and unicode methods startswith() and endswith() now accept
131 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
132
Brett Cannonde3b0522006-06-08 17:00:45 +0000133- Buffer objects, at the C level, never used the char buffer
134 implementation even when the char buffer for the wrapped object was
135 explicitly requested (originally returned the read or write buffer).
136 Now a TypeError is raised if the char buffer is not present but is
137 requested.
138
Georg Brandlddbaa662006-06-04 21:56:52 +0000139- Patch #1346214: Statements like "if 0: suite" are now again optimized
140 away like they were in Python 2.4.
141
Georg Brandlb7c8f542006-05-27 12:30:25 +0000142- Builtin exceptions are now full-blown new-style classes instead of
143 instances pretending to be classes, which speeds up exception handling
144 by about 80% in comparison to 2.5a2.
145
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000146- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
147 Unicode 4.1.
148
Georg Brandlf4ef1162006-05-26 18:03:31 +0000149- Patch #921466: sys.path_importer_cache is now used to cache valid and
150 invalid file paths for the built-in import machinery which leads to
151 fewer open calls on startup.
152
Tim Peters696cf432006-05-24 21:10:40 +0000153- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
154 of-2 bases. The largest speedup is for inputs with about 1000 decimal
155 digits. Conversion from non-power-of-2 bases remains quadratic-time in
156 the number of input digits (it was and remains linear-time for bases
157 2, 4, 8, 16 and 32).
158
Tim Petersb713ec22006-05-23 18:45:30 +0000159- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
160 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
161 an integer close to ``sys.maxint``. This was repaired by patch
162 #1335972, which also gives a nice speedup.
163
Richard Jonescebbefc2006-05-23 18:28:17 +0000164- Patch #1337051: reduced size of frame objects.
165
166- PyErr_NewException now accepts a tuple of base classes as its
167 "base" parameter.
168
Richard Jones7c88dcc2006-05-23 10:37:38 +0000169- Patch #876206: function call speedup by retaining allocated frame
170 objects.
171
Georg Brandl7b90e162006-05-18 07:01:27 +0000172- Bug #1462152: file() now checks more thoroughly for invalid mode
173 strings and removes a possible "U" before passing the mode to the
174 C library function.
175
Neal Norwitz1004a532006-05-15 07:17:23 +0000176- Patch #1488312, Fix memory alignment problem on SPARC in unicode
177
Neal Norwitz373f0a72006-05-15 07:04:36 +0000178- Bug #1487966: Fix SystemError with conditional expression in assignment
179
Martin v. Löwis879768d2006-05-11 13:28:43 +0000180- WindowsError now has two error code attributes: errno, which carries
181 the error values from errno.h, and winerror, which carries the error
182 values from winerror.h. Previous versions put the winerror.h values
183 (from GetLastError()) into the errno attribute.
184
Martin v. Löwis77736712006-05-04 05:51:03 +0000185- Patch #1475845: Raise IndentationError for unexpected indent.
186
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000187- Patch #1479181: split open() and file() from being aliases for each other.
188
Tim Peters44bd9862006-06-01 13:49:23 +0000189- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
190 methods were always silently ignored by dictionaries when comparing keys.
191 They are now passed through (except when using the C API function
192 ``PyDict_GetItem()``, whose semantics did not change).
193
194- Bug #1456209: In some obscure cases it was possible for a class with a
195 custom ``__eq__()`` method to confuse dict internals when class instances
196 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
197 No, you don't have any code that did this ;-)

203
204- Patch #1462338: Upgrade pyexpat to expat 2.0.0
205
Brett Cannon6ee7d012006-06-08 16:23:04 +0000206- Change binascii.hexlify to accept a read-only buffer instead of only a char
207 buffer and actually follow its documentation.
208
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000209- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
210
Nick Coghlanc649ec52006-05-29 12:43:05 +0000211- Patch #1478788 (modified version): The functional extension module has
212 been renamed to _functools and a functools Python wrapper module added.
213 This provides a home for additional function related utilities that are
214 not specifically about functional programming. See PEP 309.
215
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000216- Patch #1493701: performance enhancements for struct module.

224 enabled builds on Windows and systems with Posix threads support.
225
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000226- On Win32, os.listdir now supports arbitrarily-long Unicode path names
227 (up to the system limit of 32K characters).
228
229- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
230 As a result, these functions now raise WindowsError instead of OSError.
231
Tim Peters7a822da2006-05-25 21:50:17 +0000232- ``time.clock()`` on Win64 should use the high-performance Windows
233 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
234 Windows platforms).
235
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000236- Calling Tk_Init twice is refused if the first call failed as that
237 may deadlock.
238
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000239- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
240 accept it without potentially using an uninitialized pointer.
241
242- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
243 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
244 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000245
Gregory P. Smith372b5832006-06-05 18:48:21 +0000246- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.

248
Gregory P. Smith372b5832006-06-05 18:48:21 +0000249- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
250 parameter is supplied. [SF pybsddb bug #1477863]
251
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000252- bsddb: the __len__ method of a DB object has been fixed to return correct
253 results. It could previously incorrectly return 0 in some cases.
254 Fixes SF bug 1493322 (pybsddb bug 1184012).
255
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000256- bsddb: the bsddb.dbtables Modify method now raises the proper error and
257 aborts the db transaction safely when a modifier callback fails.
258 Fixes SF python patch/bug #1408584.
259
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000260- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000261 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000262 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
263 database calls that would previously deadlock. [SF python bug #775414]
264
Vinay Sajip28e57612006-07-01 10:45:20 +0000265- Patch #1446489: add support for the ZIP64 extensions to zipfile.

294
Tim Peters43898b42006-06-14 04:09:25 +0000295- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
296 guarantee that adjacent triples in the return list always describe
297 non-adjacent blocks. Previously, a pair of matching blocks could end
298 up being described by multiple adjacent triples that formed a partition
299 of the matching pair.

Nick Coghlan676725d2006-06-08 13:54:49 +0000311- The functions update_wrapper() and wraps() have been added to the functools
312 module. These make it easier to copy relevant metadata from the original
313 function when writing wrapper functions.
314
Tim Petersd6a9eef2006-06-05 01:48:21 +0000315- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
316 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000317
Martin v. Löwis3f767792006-06-04 19:36:28 +0000318- Patch #1359618: Speed up charmap encoder by using a trie structure
319 for lookup.
320
Tim Petersd609b1a2006-06-02 23:22:51 +0000321- The functions in the ``pprint`` module now sort dictionaries by key
322 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
323 if and only if its display required more than one line, although that
324 wasn't documented. The new behavior increases predictability; e.g.,
325 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
326
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000327- Patch #1497027: try HTTP digest auth before basic auth in urllib2
328 (thanks for J. J. Lee).
329
Georg Brandl2b330372006-05-28 20:23:12 +0000330- Patch #1496206: improve urllib2 handling of passwords with respect to
331 default HTTP and HTTPS ports.
332
George Yoshidaf3c65de2006-05-28 16:39:09 +0000333- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
334
Bob Ippolito7298f272006-05-23 18:43:47 +0000335- Patch #1281707: speed up gzip.readline.
336
Georg Brandlb89316f2006-05-17 15:51:16 +0000337- Patch #1180296: Two new functions were added to the locale module:
338 format_string() to get the effect of "format % items" but locale-aware,
339 and currency() to format a monetary number with currency sign.
340
Georg Brandle3a25832006-05-17 14:56:04 +0000341- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
342 and several features added, such as speed and geometry control.
343
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000344- Patch #1488881: add support for external file objects in bz2 compressed
345 tarfiles.
346
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000347- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
348 stdout arguments, making it possible to redirect input and output
349 for remote debugging.
350
351- Patch #1484695: Update the tarfile module to version 0.8. This fixes
352 a couple of issues, notably handling of long file names using the
353 GNU LONGNAME extension.
354
355- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
356 new flag when ``name`` is already the name of an option flag.
357
358- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
359 package.
360
361- Patch #1472854: make the rlcompleter.Completer class usable on non-
362 UNIX platforms.
363
364- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
365
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000366- Bug #1472827: correctly escape newlines and tabs in attribute values in
367 the saxutils.XMLGenerator class.

374
Martin v. Löwis222c5152006-06-03 07:37:13 +0000375- OpenBSD 3.9 is supported now.
376
Martin v. Löwisa43190b2006-05-22 09:15:18 +0000377- Patch #1492356: Port to Windows CE.

Neal Norwitz58e28882006-05-19 07:00:58 +0000379- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
380
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000381- Patch #1471883: Add --enable-universalsdk.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000397What's New in Python 2.5 alpha 2?
398=================================
399
400*Release date: 27-APR-2006*
401
402Core and builtins
403-----------------
404
Thomas Heller1b046642006-04-18 18:51:06 +0000405- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
406 by converting these apis from macros into exported functions again:
407
408 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
409 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
410 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
411 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
412 PyRun_String Py_CompileString
413
Martin v. Löwis45294a92006-04-18 06:24:08 +0000414- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
415
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000416- All uses of PyStructSequence_InitType have been changed to initialize
417 the type objects only once, even if the interpreter is initialized
418 multiple times.
419
Neal Norwitz61546162006-04-14 05:20:28 +0000420- Bug #1454485, array.array('u') could crash the interpreter. This was
421 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
422 to unicode when it didn't make sense. 'u#' now requires a unicode string.
423
424- Py_UNICODE is unsigned. It was always documented as unsigned, but
425 due to a bug had a signed value in previous versions.
426
Tim Peters3a5e8b12006-04-11 01:44:07 +0000427- Patch #837242: ``id()`` of any Python object always gives a positive
428 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
429 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000430 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000431 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000432
Tim Peters3a5e8b12006-04-11 01:44:07 +0000433 def __hash__(self):
434 return id(self) # WRONG
435
436 because a hash result must be a (short) Python int but it was always
437 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000438 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000439 was always usable as a hash value before this patch. That's no longer
440 necessarily so.
441
442- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000443 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000444 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000445 #1454844)
446
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000447- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
448 involving generators that have paused outside of any ``try`` or ``with``
449 blocks. (In 2.5a1, a paused generator that was part of a reference
450 cycle could not be garbage collected, regardless of whether it was
451 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000453Extension Modules

458
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000459- Bug #1467952: os.listdir() now correctly raises an error if readdir()
460 fails with an error condition.
461
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000462- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
463
464- Bug #1117761: bsddb.*open() no longer raises an exception when using
465 the cachesize parameter.
466
467- Bug #1149413: bsddb.*open() no longer raises an exception when using
468 a temporary db (file=None) with the 'n' flag to truncate on open.
469
470- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
471 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000472
Armin Rigoa9017c32006-04-19 11:50:27 +0000473- Patch #1062014: AF_UNIX sockets under Linux have a special
474 abstract namespace that is now fully supported.
475
Anthony Baxter51bcb682006-04-05 14:51:42 +0000476Library
477-------
478
Tim Peters711bf302006-04-25 03:31:36 +0000479- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
480 a doctest to be skipped (the code is not run, and the expected output
481 or exception is ignored).
482
Nick Coghlanda2268f2006-04-24 04:37:15 +0000483- Fixed contextlib.nested to cope with exceptions being raised and
484 caught inside exit handlers.
485
Greg Wardab05edc2006-04-23 03:47:58 +0000486- Updated optparse module to Optik 1.5.1 (allow numeric constants in
487 hex, octal, or binary; add ``append_const`` action; keep going if
488 gettext cannot be imported; added ``OptionParser.destroy()`` method;
489 added ``epilog`` for better help generation).
490
Tim Peters21fbd572006-04-21 21:18:10 +0000491- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
492 called from a thread spawned as a side effect of importing a module.
493
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000494- The pydoc module now supports documenting packages contained in
495 .zip or .egg files.
496
497- The pkgutil module now has several new utility functions, such
498 as ``walk_packages()`` to support working with packages that are either
499 in the filesystem or zip files.
500
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000501- The mailbox module can now modify and delete messages from
502 mailboxes, in addition to simply reading them. Thanks to Gregory
503 K. Johnson for writing the code, and to the 2005 Google Summer of
504 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000505
Tim Petersc7605f22006-04-17 21:12:33 +0000506- The ``__del__`` method of class ``local`` in module ``_threading_local``
507 returned before accomplishing any of its intended cleanup.
508
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000509- Patch #790710: Add breakpoint command lists in pdb.
510
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000511- Patch #1063914: Add Tkinter.Misc.clipboard_get().
512
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000513- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
514
Anthony Baxtere29002c2006-04-12 12:07:31 +0000515- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
516 Windows. Bug #1469163.
517
Phillip J. Eby47032112006-04-11 01:07:43 +0000518- The warnings, linecache, inspect, traceback, site, and doctest modules
519 were updated to work correctly with modules imported from zipfiles or
520 via other PEP 302 __loader__ objects.
521
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000522- Patch #1467770: Reduce usage of subprocess._active to processes which
523 the application hasn't waited on.
524

530 direct output to an alternate file-like object.
531
Anthony Baxter51bcb682006-04-05 14:51:42 +0000532Build
533-----
534
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000535- The Makefile now has a reindent target, which runs reindent.py on
536 the library.
537
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000538- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000541
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000542- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
543 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000544 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000545 CXX from --with-cxx-main, see description in README.
546
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000547- Patch #1429775: Link extension modules with the shared libpython.
548
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000549- Fixed a libffi build problem on MIPS systems.
550
Tim Peters8931ff12006-05-13 23:28:20 +0000551- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
552 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
553 and "%zu" for unsigned integers of type ``size_t``.
554
Anthony Baxter51bcb682006-04-05 14:51:42 +0000555Tests
556-----
557
Nick Coghlanda2268f2006-04-24 04:37:15 +0000558- test_contextlib now checks contextlib.nested can cope with exceptions
559 being raised and caught inside exit handlers.
560
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000561- test_cmd_line now checks operation of the -m and -c command switches
562
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000563- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
564 it separately and by hand. It also wasn't cleaning up its changes to
565 the current Decimal context.
566
Thomas Woutersabd08882006-04-26 15:53:30 +0000567- regrtest.py now has a -M option to run tests that test the new limits of
568 containers, on 64-bit architectures. Running these tests is only sensible
569 on 64-bit machines with more than two gigabytes of memory. The argument
570 passed is the maximum amount of memory for the tests to use.

579-------------
580
Tim Petersb06d28c2006-05-12 01:57:59 +0000581- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
582
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000583- PEP 343: Added Context Types section to the library reference
584 and attempted to bring other PEP 343 related documentation into
585 line with the implementation and/or python-dev discussions.
586
Tim Peters8dc73d22006-04-24 02:03:16 +0000587- Bug #1337990: clarified that ``doctest`` does not support examples
588 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000591What's New in Python 2.5 alpha 1?
592=================================
593
Anthony Baxterebed3f62006-04-03 15:03:44 +0000594*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000595
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000596Core and builtins
597-----------------
598
Nick Coghlan43832302006-04-23 17:04:07 +0000599- PEP 338: -m command line switch now delegates to runpy.run_module
600 allowing it to support modules in packages and zipfiles
601
Martin v. Löwisc661b882006-04-20 04:54:23 +0000602- On Windows, .DLL is not an accepted file name extension for
603 extension modules anymore; extensions are only found if they
604 end in .PYD.
605
Martin v. Löwisea62d252006-04-03 10:56:49 +0000606- Bug #1421664: sys.stderr.encoding is now set to the same value as
607 sys.stdout.encoding.
608
Neal Norwitz92e212f2006-04-03 04:48:37 +0000609- __import__ accepts keyword arguments.
610
Georg Brandlccadf842006-03-31 18:54:53 +0000611- Patch #1460496: round() now accepts keyword arguments.
612
Anthony Baxter262c00a2006-03-30 10:53:17 +0000613- Fixed bug #1459029 - unicode reprs were double-escaped.
614
Hye-Shik Changd478f342006-03-23 12:32:36 +0000615- Patch #1396919: The system scope threads are reenabled on FreeBSD
616 5.4 and later versions.
617
Neal Norwitze98ccf62006-03-23 05:39:47 +0000618- Bug #1115379: Compiling a Unicode string with an encoding declaration
619 now gives a SyntaxError.
620
Georg Brandlabd1ff82006-03-18 07:59:59 +0000621- Previously, Python code had no easy way to access the contents of a
622 cell object. Now, a ``cell_contents`` attribute has been added
623 (closes patch #1170323).
624
Tim Peterscf79aac2006-03-16 01:14:46 +0000625- Patch #1123430: Python's small-object allocator now returns an arena to
626 the system ``free()`` when all memory within an arena becomes unused
627 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
628 freed. Some applications will see a drop in virtual memory size now,
629 especially long-running applications that, from time to time, temporarily
630 use a large number of small objects. Note that when Python returns an
631 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000632 platform C library will in turn return that memory to the operating system.
633 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000634 appears to be effective at least on Microsoft C and gcc-based systems.
635 Thanks to Evan Jones for hard work and patience.
636
Georg Brandl533ff6f2006-03-08 18:09:27 +0000637- Patch #1434038: property() now uses the getter's docstring if there is
638 no "doc" argument given. This makes it possible to legitimately use
639 property() as a decorator to produce a read-only property.
640
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000641- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
642 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
643 of requiring an int or long in slicing and a few other contexts, enabling
644 other objects (e.g. Numeric Python's integers) to be used as slice indices.
645
Neal Norwitz995acdf2006-03-07 05:01:00 +0000646- Fixed various bugs reported by Coverity's Prevent tool.
647
Brett Cannonbf364092006-03-01 04:25:17 +0000648- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
649 new exception base class, BaseException, which has a new message attribute.
650 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
651 Raising a string exception now raises a DeprecationWarning.
652
Thomas Woutersfb609f42006-02-28 16:37:25 +0000653- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
654 explicitly relative, using 'from .module import name' to mean 'from the same
655 package as this module is in. Imports without dots still default to the
656 old relative-then-absolute, unless 'from __future__ import
657 absolute_import' is used.
658
Brett Cannona7446e32006-02-27 23:39:10 +0000659- Properly check if 'warnings' raises an exception (usually when a filter set
660 to "error" is triggered) when raising a warning for raising string
661 exceptions.
662
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000663- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000664 The name was removed from Include/code.h.
665
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000666- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000667
Guido van Rossum1968ad32006-02-25 22:38:04 +0000668- Patch 1433928:
669 - The copy module now "copies" function objects (as atomic objects).
670 - dict.__getitem__ now looks for a __missing__ hook before raising
671 KeyError.
672
Tim Peters84ef21c2006-02-28 20:39:06 +0000673- PEP 343: with statement implemented. Needs ``from __future__ import
674 with_statement``. Use of 'with' as a variable will generate a warning.
675 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000676 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000677 The following objects have __context__ methods:
678 - The built-in file type.
679 - The thread.LockType type.
680 - The following types defined by the threading module:
681 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
682 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000683
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000684- Fix the encodings package codec search function to only search
685 inside its own package. Fixes problem reported in patch #1433198.
686
687 Note: Codec packages should implement and register their own
688 codec search function. PEP 100 has the details.
689
Tim Peters9ea89d22006-06-04 03:26:02 +0000690- PEP 353: Using ``Py_ssize_t`` as the index type.
691
692- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
693 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
694 now allow Python to make use of memory blocks exceeding 2**32 bytes for
695 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
696 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000697
Neal Norwitzfc76d632006-01-10 06:03:13 +0000698- Patch #1400181, fix unicode string formatting to not use the locale.
699 This is how string objects work. u'%f' could use , instead of .
700 for the decimal point. Now both strings and unicode always use periods.
701
Neal Norwitz671b9e32006-01-09 07:07:12 +0000702- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
703 configure would break checking curses.h.
704
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000705- Bug #959576: The pwd module is now builtin. This allows Python to be
706 built on UNIX platforms without $HOME set.
707
Neal Norwitzc10978f2005-12-19 06:07:16 +0000708- Bug #1072182, fix some potential problems if characters are signed.
709
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000710- Bug #889500, fix line number on SyntaxWarning for global declarations.
711
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000712- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
713
Neal Norwitze7214a12005-12-18 05:03:17 +0000714- Support for converting hex strings to floats no longer works.
715 This was not portable. float('0x3') now raises a ValueError.
716
Barry Warsaw2a38a862005-12-18 01:27:35 +0000717- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000718 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000719 is now displayed in interactive prompt banner.
720
Georg Brandlfa166682005-12-17 21:45:17 +0000721- Implementation of PEP 341 - Unification of try/except and try/finally.
722 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000723 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000724
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000725- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
726 now encodes backslash correctly.
727
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000728- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
729
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000730- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000731 and long longs.
732
Neal Norwitz67715f02005-11-09 06:59:35 +0000733- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000734 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000735 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000736
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000737- Replaced most Unicode charmap codecs with new ones using the
738 new Unicode translate string feature in the builtin charmap
739 codec; the codecs were created from the mapping tables available
740 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
741 encodings now include a mapping for the Apple logo)
742
Tim Peterse3547fd2005-12-16 23:13:57 +0000743- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000744
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000745- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000746
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000747- A new AST parser implementation was completed. The abstract
748 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000749 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000750
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000751- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000752 The following code now raises a SyntaxError: foo(a = i for i in range(10))
753
Neal Norwitz708e51a2005-10-03 04:48:15 +0000754- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
755
Neal Norwitz11bd1192005-10-03 00:54:56 +0000756- SF Bug #887946: fix segfault when redirecting stdin from a directory.
757 Provide a warning when a directory is passed on the command line.
758
Neal Norwitz40d37812005-10-02 01:48:49 +0000759- Fix segfault with invalid coding.
760
761- SF bug #772896: unknown encoding results in MemoryError.
762
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000763- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000764 supported a __len__() method which evaluated to False when the iterator
765 was empty.
766
Guido van Rossum630db602005-09-20 18:49:54 +0000767- On 64-bit platforms, when __len__() returns a value that cannot be
768 represented as a C int, raise OverflowError.
769
Skip Montanarof8948ca2005-09-19 03:54:46 +0000770- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000771 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000772
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000773- SF bug #893549: parsing keyword arguments was broken with a few format
774 codes.
775
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000776- Changes donated by Elemental Security to make it work on AIX 5.3
777 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
778 bug #105470: test_pwd fails on 64bit system (Opteron).
779
Guido van Rossum539c6622005-09-14 17:49:54 +0000780- Changes donated by Elemental Security to make it work on HP-UX 11 on
781 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
782
Georg Brandl4550b8d2005-08-26 06:43:52 +0000783- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000784 (fixes bug #1119418).
785
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000786- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
787
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000788- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
789 exceptions that cause a function to exit.
790
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000791- The implementation of set() and frozenset() was revised to use its
792 own internal data structure. Memory consumption is reduced by 1/3
793 and there are modest speed-ups as well. The API is unchanged.
794
Tim Petersde7990b2005-07-17 23:45:23 +0000795- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
796
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000797- SF bug #1229429: PyObject_CallMethod failed to decrement some
798 reference counts in some error exit cases.
799
Tim Petersecc6e6a2005-07-10 22:30:55 +0000800- SF bug #1185883: Python's small-object memory allocator took over
801 a block managed by the platform C library whenever a realloc specified
802 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000803 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000804 portable way to copy data from the C-managed block into Python's
805 small-object space without risking a memory fault. Python's small-object
806 realloc now leaves such blocks under the control of the platform C
807 realloc.
808
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000809- SF bug #1232517: An overflow error was not detected properly when
810 attempting to convert a large float to an int in os.utime().
811
Raymond Hettinger3296e692005-06-29 23:29:56 +0000812- SF bug #1224347: hex longs now print with lowercase letters just
813 like their int counterparts.
814
Michael W. Hudson188d4362005-06-20 16:52:57 +0000815- SF bug #1163563: the original fix for bug #1010677 ("thread Module
816 Breaks PyGILState_Ensure()") broke badly in the case of multiple
817 interpreter states; back out that fix and do a better job (see
818 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
819 for a longer write-up of the problem).
820
Michael W. Hudsondf888462005-06-03 14:41:55 +0000821- SF patch #1180995: marshal now uses a binary format by default when
822 serializing floats.
823
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000824- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
825 the routines that promise to produce IEEE 754 binary representations
826 of floats now simply copy bytes around.
827
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000828- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
829 278.
830
Brett Cannonc3647ac2005-04-26 03:45:26 +0000831- patch #1109424: int, long, float, complex, and unicode now check for the
832 proper magic slot for type conversions when subclassed. Previously the
833 magic slot was ignored during conversion. Semantics now match the way
834 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000835 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000836 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000837 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000838
Barry Warsawc8d907c2005-04-19 23:43:40 +0000839- Descriptors defined in C with a PyGetSetDef structure, where the setter is
840 NULL, now raise an AttributeError when attempting to set or delete the
841 attribute. Previously a TypeError was raised, but this was inconsistent
842 with the equivalent pure-Python implementation.
843
Michael W. Hudson774479c2005-04-18 08:46:17 +0000844- It is now safe to call PyGILState_Release() before
845 PyEval_InitThreads() (note that if there is reason to believe there
846 are multiple threads around you still must call PyEval_InitThreads()
847 before using the Python API; this fix is for extension modules that
848 have no way of knowing if Python is multi-threaded yet).
849
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000850- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
851 disabled caused a crash.
852
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000853- Bug #1165306: instancemethod_new allowed the creation of a method
854 with im_class == im_self == NULL, which caused a crash when called.
855
Tim Petersecc6e6a2005-07-10 22:30:55 +0000856- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000857 fixes the crash seen in bug #1165761
858
Raymond Hettinger96229b12005-03-11 06:49:40 +0000859- Added two new builtins, any() and all().
860
Brett Cannon409d8f22005-03-05 06:47:57 +0000861- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000862 (e.g., ``class C(): pass`` is no longer a syntax error).
863 Patch #1176012 added support to the 'parser' module and 'compiler' package
864 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000865
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000866- Patch #1115086: Support PY_LONGLONG in structmember.
867
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000868- Bug #1155938: new style classes did not check that __init__() was
869 returning None.
870
Tim Petersecc6e6a2005-07-10 22:30:55 +0000871- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000872 ('\') with a specific error message.
873
Martin v. Löwisff232d72005-03-03 09:24:38 +0000874- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
875
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000876- Bug #1124295: the __name__ attribute of file objects was
877 inadvertently made inaccessible in restricted mode.
878
Tim Petersecc6e6a2005-07-10 22:30:55 +0000879- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000880 an ferror() call.
881
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000882- min() and max() now support key= arguments with the same meaning as in
883 list.sort().
884
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000885- The peephole optimizer now performs simple constant folding in expressions:
886 (2+3) --> (5).
887
Raymond Hettingera422c342005-01-11 03:03:27 +0000888- set and frozenset objects can now be marshalled. SF #1098985.
889
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000890- Bug #1077106: Poor argument checking could cause memory corruption
891 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000892
Jeremy Hyltonab630502005-02-04 18:44:06 +0000893- The parser did not complain about future statements in illegal
894 positions. It once again reports a syntax error if a future
895 statement occurs after anything other than a doc string.
896
Neil Schemenauercf52c072005-08-12 17:34:58 +0000897- Change the %s format specifier for str objects so that it returns a
898 unicode instance if the argument is not an instance of basestring and
899 calling __str__ on the argument returns a unicode instance.
900
Tim Petersf4e69282006-02-27 17:15:31 +0000901- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
902 current thread state when the auto-GIL-state machinery knows about
903 it (since the thread state is being deleted, continuing to remember it
904 can't help, but can hurt if another thread happens to get created with
905 the same thread id).

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001094Library
1095-------
1096
Nick Coghlan43832302006-04-23 17:04:07 +00001097- PEP 338: new module runpy defines a run_module function to support
1098 executing modules which provide access to source code or a code object
1099 via the PEP 302 import mechanisms.
1100
Anthony Baxter93f5b932006-04-03 08:05:07 +00001101- The email module's parsedate_tz function now sets the daylight savings

1109 in attribute values.
1110
Anthony Baxterc51ee692006-04-01 00:57:31 +00001111- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001112 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001113 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001114 module will not be built.
1115
Tim Petersc17976e2006-04-01 00:26:53 +00001116- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1117 aren't officially supported here, and trying to use them will probably
1118 raise an exception some day. But dicts have been allowed, and "mostly
1119 worked", so support for them won't go away without warning.
1120
Georg Brandl338ef7d2006-03-31 18:42:16 +00001121- Bug #1445068: getpass.getpass() can now be given an explicit stream
1122 argument to specify where to write the prompt.
1123
Georg Brandl22ec80b2006-03-31 18:25:44 +00001124- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1139
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001140- email 4.0 package now integrated. This is largely the same as the email 3.0
1141 package that was included in Python 2.3, except that PEP 8 module names are
1142 now used (e.g. mail.message instead of email.Message). The MIME classes
1143 have been moved to a subpackage (e.g. email.mime.text instead of
1144 email.MIMEText). The old names are still supported for now. Several
1145 deprecated Message methods have been removed and lots of bugs have been
1146 fixed. More details can be found in the email package documentation.
1147
Walter Dörwald40108c92006-03-27 08:15:44 +00001148- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1149 (a subclass of tuple) that provides incremental decoders and encoders
1150 (a way to use stateful codecs without the stream API). Python functions
1151 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1152 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1153 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001154
Walter Dörwald067db482006-03-15 22:17:27 +00001155- Patch #1359365: Calling next() on a closed StringIO.String object raises
1156 a ValueError instead of a StopIteration now (like file and cString.String do).
1157 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1158 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001159
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001160- A regrtest option -w was added to re-run failed tests in verbose mode.

1163 interpreter to exit.
1164
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001165- The function get_count() has been added to the gc module, and gc.collect()
1166 grew an optional 'generation' argument.
1167
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001168- A library msilib to generate Windows Installer files, and a distutils
1169 command bdist_msi have been added.
1170
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001171- PEP 343: new module contextlib.py defines decorator @contextmanager

1236
1237 "The consensus of researchers in this area (at least as
1238 expressed at the NIST Hash Function Workshop 10/31/05),
1239 is that SHA-256 is a good choice for the time being, but
1240 that research should continue, and other alternatives may
1241 arise from this research. The larger SHA's also seem OK."

1429 dictates.
1430 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001431 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001432 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001433 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1434 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001435 + reader now allows \r characters to be quoted (previously it only allowed
1436 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001437 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001438 + Dialect classes passed to the module are no longer instantiated by
1439 the module before being parsed (the former validation scheme required
1440 this, but the mechanism was unreliable).
1441 + The dialect registry now contains instances of the internal
1442 C-coded dialect type, rather than references to python objects.
1443 + the internal c-coded dialect type is now immutable.
1444 + register_dialect now accepts the same keyword dialect specifications
1445 as the reader and writer, allowing the user to register dialects
1446 without first creating a dialect class.
1447 + a configurable limit to the size of parsed fields has been added -
1448 previously, an unmatched quote character could result in the entire
1449 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001450 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001451 the parser field size limit (returning the former limit). The initial
1452 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001453 + A line_num attribute has been added to the reader object, which tracks
1454 the number of lines read from the source iterator. This is not
1455 the same as the number of records returned, as records can span
1456 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001457 + reader and writer objects were not being registered with the cyclic-GC.
1458 This has been fixed.
1459
Brett Cannone6539c42005-01-08 02:43:53 +00001460- _DummyThread objects in the threading module now delete self.__block that is
1461 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1462 lock primitives tend to be limited in number and thus should not be wasted on
1463 a _DummyThread object. Fixes bug #1089632.
1464
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001465- The imghdr module now detects Exif files.
1466
Raymond Hettinger6065d322004-12-20 23:51:53 +00001467- StringIO.truncate() now correctly adjusts the size attribute.
1468 (Bug #951915).
1469
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001470- locale.py now uses an updated locale alias table (built using
1471 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1472 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001473 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001474
Raymond Hettinger3557f422004-12-07 12:02:02 +00001475- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1476
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001477- the pickle module no longer accepts the deprecated None option in the
1478 args tuple returned by __reduce__().
1479
Brett Cannon84667c02004-12-07 03:25:18 +00001480- optparse now optionally imports gettext. This allows its use in setup.py.
1481
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001482- the pickle module no longer uses the deprecated bin parameter.
1483
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001484- the shelve module no longer uses the deprecated binary parameter.
1485

1487
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001488- the filecmp module no longer uses the deprecated use_statcache argument.
1489
Raymond Hettinger664347b2004-12-04 21:21:53 +00001490- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1491 extended or overridden by subclasses. Formerly, the subclassed method would
1492 be ignored by the rest of the module. (Bug #1078905).
1493
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001494- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001495 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001496
Walter Dörwald36733692004-12-22 12:50:50 +00001497- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1498 once when a size argument is given. This prevents a buffer overflow in the
1499 tokenizer with very long source lines.
1500
Barry Warsaw538561e2006-01-01 21:48:54 +00001501- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1502 immediately after creating the object, without any intervening
1503 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001504
Skip Montanaro05885812005-01-16 20:48:27 +00001505- The reconvert.quote function can now emit triple-quoted strings. The
1506 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001507
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001508- ``UserString.MutableString`` now supports negative indices in
1509 ``__setitem__`` and ``__delitem__``
1510
Greg Ward40407942005-03-05 02:53:17 +00001511- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1512 correctly.
1513
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001514- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1515 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1516 character even if the user has passed a size parameter to get a proper
1517 line ending. Remove the special handling of a "\r\n" that has been split
1518 between two lines.
1519
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001520- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1521 about illegal code points. The codec now supports PEP 293 style error
1522 handlers.
1523
Walter Dörwald78a78b02005-09-01 12:04:29 +00001524- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001525 from the input stream, so that the output is a byte string in the correct
1526 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001527
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001528- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1529 considering it exactly like a '*'.
1530
Walter Dörwald007f8df2005-10-09 19:42:27 +00001531- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1532 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001533
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001534- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1535
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001536- Patch #1413711: Certain patterns of differences were making difflib
1537 touch the recursion limit.
1538
Walter Dörwald58917a62006-03-31 15:26:22 +00001539- Bug #947906: An object oriented interface has been added to the calendar
1540 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001541 called as a script (e.g. via ``python -mcalendar``). Localized month and
1542 weekday names can be ouput (even if an exotic encoding is used) using
1543 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001544

1547
Neal Norwitz602d3392006-03-31 08:21:40 +00001548- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1549 by using -mieee gcc option.
1550
Martin v. Löwis86d66262006-02-17 08:40:11 +00001551- Patch #1432345: Make python compile on DragonFly.
1552
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001553- Build support for Win64-AMD64 was added.
1554
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001555- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1556
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001557- Patch #881820: look for openpty and forkpty also in libbsd.
1558
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001559- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1560 The zlib module is now builtin on Windows.
1561
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001562- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1563
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001564- Bug #1189330: configure did not correctly determine the necessary
1565 value of LINKCC if python was built with GCC 4.0.
1566
Trent Mick8321b422005-07-26 02:29:21 +00001567- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1568 vulnerability in zlib 1.2.1 and 1.2.2.
1569
Brett Cannon08cd5982005-04-24 22:26:38 +00001570- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1571 flags that change binary compatibility. Changes were also made to
1572 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001573 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001574
Bob Ippolitoed233462005-03-29 13:47:59 +00001575- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1576 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1577 no longer exists). This configure patch makes things right.
1578
Martin v. Löwise2713be2005-03-08 15:03:08 +00001579- Bug #1158607: Build with --disable-unicode again.
1580
Brett Cannon46d96232005-02-16 00:07:19 +00001581- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1582 defined. Discovered as a result of not being able to build on OS X.
1583
Brett Cannon516592f2004-12-07 00:42:59 +00001584- setup.py now uses the directories specified in LDFLAGS using the -L option
1585 and in CPPFLAGS using the -I option for adding library and include
1586 directories, respectively, for compiling extension modules against. This has
1587 led to the core being compiled using the values in CPPFLAGS. It also removes
1588 the need for the special-casing of both DarwinPorts and Fink for darwin since
1589 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1590 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1591 Fink, ``-I/opt/local/include`` for DarwinPorts).
1592
Brett Cannon43802422005-02-10 20:48:03 +00001593- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1594 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1595 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1596 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001598C API
1599-----
1600
Tim Petersc9d78aa2006-03-26 23:27:58 +00001601- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1602 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1603 is obtained via the ``PyObject_`` family, it must be released via the
1604 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1605 always been officially true, but when Python's small-object allocator was
1606 introduced, an attempt was made to cater to a few extension modules
1607 discovered at the time that obtained memory via ``PyObject_New`` but
1608 released it via ``PyMem_DEL``. It's years later, and if such code still
1609 exists it will fail now (probably with segfaults, but calling wrong
1610 low-level memory management functions can yield many symptoms).
1611
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001612- Added a C API for set and frozenset objects.
1613
Raymond Hettinger66517482004-12-03 11:45:13 +00001614- Removed PyRange_New().
1615
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001616- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1617 mapping argument now. This string is used as a mapping table. Byte values
1618 greater than the length of the string and 0xFFFE are treated as undefined
1619 mappings.
