12Core and builtins
13-----------------
14
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000015- Bug #1441486: The literal representation of -(sys.maxint - 1)
16 again evaluates to a int object, not a long.
17
Neil Schemenauer0e07b602006-07-09 16:16:34 +000018- Bug #1501934: The scope of global variables that are locally assigned
19 using augmented assignment is now correctly determined.
20
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000021- Bug #927248: Recursive method-wrapper objects can now safely
22 be released.
23
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000024- Bug #1417699: Reject locale-specific decimal point in float()
25 and atof().
26
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000027- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
28 omit a default "error" argument for NULL pointer. This allows
29 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000030
Neal Norwitzfb48afa2006-07-08 05:31:37 +000031- Bug #1519018: 'as' is now validated properly in import statements.
32
Neal Norwitz28746ab2006-07-09 22:14:42 +000033- On 64 bit systems, int literals that use less than 64 bits are
34 now ints rather than longs.
35
Neal Norwitzed657552006-07-10 00:04:44 +000036- Bug #1512814, Fix incorrect lineno's when code at module scope
37 started after line 256.
38
Tim Peters32a83612006-07-10 21:08:24 +000039- New function ``sys._current_frames()`` returns a dict mapping thread
40 id to topmost thread stack frame. This is for expert use, and is
41 especially useful for debugging application deadlocks. The functionality
42 was previously available in Fazal Majid's ``threadframe`` extension
43 module, but it wasn't possible to do this in a wholly threadsafe way from
44 an extension.

50
Tim Peters32a83612006-07-10 21:08:24 +000051- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +000052 environment variable to be set in order to the SDK environment
53 for finding the compiler, include files, etc.
54
Martin v. Löwis388a8c22006-07-06 19:28:03 +000055- Bug #1515998: Properly generate logical ids for files in bdist_msi.
56
Nick Coghlan2d792252006-07-06 13:47:18 +000057- warnings.py now ignores ImportWarning by default
58
Thomas Woutersadd19112006-07-05 11:03:49 +000059- string.Template() now correctly handles tuple-values. Previously,
60 multi-value tuples would raise an exception and single-value tuples would
61 be treated as the value they contain, instead.
62
Martin v. Löwisede77f52006-07-03 13:01:35 +000063- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
64 even if some data are received.
65
Martin v. Löwis45482392006-07-03 12:28:58 +000066- Bug #1267547: Put proper recursive setup.py call into the

70 degrees and radians.
71
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000072- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +000073 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000074
Martin v. Löwisbd39c032006-07-03 09:44:00 +000075- Bug #1514703: Only setup canvas window in turtle when the canvas
76 is created.
77
Martin v. Löwis7596e832006-07-01 15:33:37 +000078- Bug #1513223: .close() of a _socketobj now releases the underlying
79 socket again, which then gets closed as it becomes unreferenced.
80
Fred Drake10497c82006-06-29 02:57:48 +000081- Bug #1504333: Make sgmllib support angle brackets in quoted
82 attribute values.
83
84- Bug #853506: Fix IPv6 address parsing in unquoted attributes in

Georg Brandl1be63af2006-06-28 20:23:25 +000087- Fix a bug in the turtle module's end_fill function.
88
Brett Cannon53ab5b72006-06-22 16:49:14 +000089- Bug #1510580: The 'warnings' module improperly required that a Warning
90 category be either a types.ClassType and a subclass of Warning. The proper
91 check is just that it is a subclass with Warning as the documentation states.
92
Georg Brandlad29e632006-06-21 17:45:17 +000093- The compiler module now correctly compiles the new try-except-finally
94 statement (bug #1509132).
95
Neal Norwitz60373cd2006-06-22 06:30:50 +000096- The wsgiref package is now installed properly on Unix.
97
Vinay Sajip28e57612006-07-01 10:45:20 +000098- A bug was fixed in logging.config.fileConfig() which caused a crash on
99 shutdown when fileConfig() was called multiple times.
100
Gerhard Häring762fbd32006-07-02 17:48:30 +0000101- The sqlite3 module did cut off data from the SQLite database at the first
102 null character before sending it to a custom converter. This has been fixed
103 now.
104
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000105Extension Modules
106-----------------
107
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000108- Assigning None to pointer type fields in ctypes structures possible
109 overwrote the wrong fields, this is fixed now.
110
111- Fixed a segfault in _ctypes when ctypes.wintypes were imported
112 on non-Windows platforms.
113
114- Bug #1518190: The ctypes.c_void_p constructor now accepts any
115 integer or long, without range checking.
116
117- Patch #1517790: It is now possible to use custom objects in the ctypes
118 foreign function argtypes sequence as long as they provide a from_param
119 method, no longer is it required that the object is a ctypes type.
120
121- The '_ctypes' extension module now works when Python is configured
122 with the --without-threads option.
123
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000124- Bug #1513646: os.access on Windows now correctly determines write
125 access, again.
126
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000127- Bug #1512695: cPickle.loads could crash if it was interrupted with
128 a KeyboardInterrupt.
129
Neal Norwitza12aa882006-07-06 06:45:08 +0000130- Bug #1296433: parsing XML with a non-default encoding and
131 a CharacterDataHandler could crash the interpreter in pyexpat.
132
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000133- Patch #1516912: improve Modules support for OpenVMS.
134
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000135Build
136-----
137
Tim Peters32a83612006-07-10 21:08:24 +0000138- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000139 Previously, the slight difference could cause compilation errors of the
140 'zlib' module on systems with more than one version of zlib.
141
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000142- The MSI compileall step was fixed to also support a TARGETDIR
143 with spaces in it.
144
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000145- Bug #1517388: sqlite3.dll is now installed on Windows independent
146 of Tcl/Tk.
147
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000148- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000149 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000150
Neal Norwitzb15ac312006-06-29 04:10:08 +0000151Tests
152-----
153
154- Call os.waitpid() at the end of tests that spawn child processes in order
155 to minimize resources (zombies).
156
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000157Documentation
158-------------
159
Nick Coghlan2d792252006-07-06 13:47:18 +0000160- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
161 documentation for the warnings module.
162
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000163- Patch #1509163: MS Toolkit Compiler no longer available.
164
Neal Norwitz56640df2006-07-10 02:36:41 +0000165- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000167What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000168================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000169
Anthony Baxterd1136802006-06-19 12:04:15 +0000170*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000171
172Core and builtins
173-----------------
174
Georg Brandla56b9152006-06-19 06:35:54 +0000175- Patch #1507676: Error messages returned by invalid abstract object operations
176 (such as iterating over an integer) have been improved and now include the
177 type of the offending object to help with debugging.
178
Brett Cannonea3912b2006-06-13 21:46:41 +0000179- Bug #992017: A classic class that defined a __coerce__() method that returned
180 its arguments swapped would infinitely recurse and segfault the interpreter.
181
Neal Norwitz909eb122006-06-12 02:13:21 +0000182- Fix the socket tests so they can be run concurrently.
183
Neal Norwitzb9845e72006-06-12 02:11:18 +0000184- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000185 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000186
Brett Cannon22565aa2006-06-09 22:31:23 +0000187- Bug #532646: object.__call__() will continue looking for the __call__
188 attribute on objects until one without one is found. This leads to recursion
189 when you take a class and set its __call__ attribute to an instance of the
190 class. Originally fixed for classic classes, but this fix is for new-style.
191 Removes the infinite_rec_3 crasher.
192
Georg Brandl24250812006-06-09 18:45:48 +0000193- The string and unicode methods startswith() and endswith() now accept
194 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
195
Brett Cannonde3b0522006-06-08 17:00:45 +0000196- Buffer objects, at the C level, never used the char buffer
197 implementation even when the char buffer for the wrapped object was
198 explicitly requested (originally returned the read or write buffer).
199 Now a TypeError is raised if the char buffer is not present but is
200 requested.
201
Georg Brandlddbaa662006-06-04 21:56:52 +0000202- Patch #1346214: Statements like "if 0: suite" are now again optimized
203 away like they were in Python 2.4.
204
Georg Brandlb7c8f542006-05-27 12:30:25 +0000205- Builtin exceptions are now full-blown new-style classes instead of
206 instances pretending to be classes, which speeds up exception handling
207 by about 80% in comparison to 2.5a2.
208
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000209- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
210 Unicode 4.1.
211
Georg Brandlf4ef1162006-05-26 18:03:31 +0000212- Patch #921466: sys.path_importer_cache is now used to cache valid and
213 invalid file paths for the built-in import machinery which leads to
214 fewer open calls on startup.
215
Tim Peters696cf432006-05-24 21:10:40 +0000216- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
217 of-2 bases. The largest speedup is for inputs with about 1000 decimal
218 digits. Conversion from non-power-of-2 bases remains quadratic-time in
219 the number of input digits (it was and remains linear-time for bases
220 2, 4, 8, 16 and 32).
221
Tim Petersb713ec22006-05-23 18:45:30 +0000222- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
223 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
224 an integer close to ``sys.maxint``. This was repaired by patch
225 #1335972, which also gives a nice speedup.
226
Richard Jonescebbefc2006-05-23 18:28:17 +0000227- Patch #1337051: reduced size of frame objects.
228
229- PyErr_NewException now accepts a tuple of base classes as its
230 "base" parameter.
231
Richard Jones7c88dcc2006-05-23 10:37:38 +0000232- Patch #876206: function call speedup by retaining allocated frame
233 objects.
234
Georg Brandl7b90e162006-05-18 07:01:27 +0000235- Bug #1462152: file() now checks more thoroughly for invalid mode
236 strings and removes a possible "U" before passing the mode to the
237 C library function.
238
Neal Norwitz1004a532006-05-15 07:17:23 +0000239- Patch #1488312, Fix memory alignment problem on SPARC in unicode
240
Neal Norwitz373f0a72006-05-15 07:04:36 +0000241- Bug #1487966: Fix SystemError with conditional expression in assignment
242
Martin v. Löwis879768d2006-05-11 13:28:43 +0000243- WindowsError now has two error code attributes: errno, which carries
244 the error values from errno.h, and winerror, which carries the error
245 values from winerror.h. Previous versions put the winerror.h values
246 (from GetLastError()) into the errno attribute.
247
Martin v. Löwis77736712006-05-04 05:51:03 +0000248- Patch #1475845: Raise IndentationError for unexpected indent.
249
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000250- Patch #1479181: split open() and file() from being aliases for each other.
251
Tim Peters44bd9862006-06-01 13:49:23 +0000252- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
253 methods were always silently ignored by dictionaries when comparing keys.
254 They are now passed through (except when using the C API function
255 ``PyDict_GetItem()``, whose semantics did not change).
256
257- Bug #1456209: In some obscure cases it was possible for a class with a
258 custom ``__eq__()`` method to confuse dict internals when class instances
259 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
260 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000262Extension Modules
263-----------------
264
Trent Mick960a3f82006-06-28 20:30:41 +0000265- Bug #1295808: expat symbols should be namespaced in pyexpat
266
267- Patch #1462338: Upgrade pyexpat to expat 2.0.0
268
Brett Cannon6ee7d012006-06-08 16:23:04 +0000269- Change binascii.hexlify to accept a read-only buffer instead of only a char
270 buffer and actually follow its documentation.
271
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000272- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
273
Nick Coghlanc649ec52006-05-29 12:43:05 +0000274- Patch #1478788 (modified version): The functional extension module has
275 been renamed to _functools and a functools Python wrapper module added.
276 This provides a home for additional function related utilities that are
277 not specifically about functional programming. See PEP 309.
278
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000279- Patch #1493701: performance enhancements for struct module.
280
Georg Brandl378d5922006-05-17 14:26:50 +0000281- Patch #1490224: time.altzone is now set correctly on Cygwin.
282
Georg Brandl8d3342b2006-05-16 07:38:27 +0000283- Patch #1435422: zlib's compress and decompress objects now have a
284 copy() method.
285
Andrew MacIntyre92913322006-06-13 15:04:24 +0000286- Patch #1454481: thread stack size is now tunable at runtime for thread
287 enabled builds on Windows and systems with Posix threads support.
288
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000289- On Win32, os.listdir now supports arbitrarily-long Unicode path names
290 (up to the system limit of 32K characters).
291
292- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
293 As a result, these functions now raise WindowsError instead of OSError.
294
Tim Peters7a822da2006-05-25 21:50:17 +0000295- ``time.clock()`` on Win64 should use the high-performance Windows
296 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
297 Windows platforms).
298
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000299- Calling Tk_Init twice is refused if the first call failed as that
300 may deadlock.
301
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000302- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
303 accept it without potentially using an uninitialized pointer.
304
305- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
306 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
307 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000308
Gregory P. Smith372b5832006-06-05 18:48:21 +0000309- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000310 [pybsddb project SF patch number 1466734]
311
Gregory P. Smith372b5832006-06-05 18:48:21 +0000312- bsddb: fix DBCursor.pget() bug with keyword argument names when no data

314
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000315- bsddb: the __len__ method of a DB object has been fixed to return correct
316 results. It could previously incorrectly return 0 in some cases.
317 Fixes SF bug 1493322 (pybsddb bug 1184012).
318
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000319- bsddb: the bsddb.dbtables Modify method now raises the proper error and
320 aborts the db transaction safely when a modifier callback fails.
321 Fixes SF python patch/bug #1408584.
322
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000323- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000324 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000325 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
326 database calls that would previously deadlock. [SF python bug #775414]

Martin v. Löwisd8251432006-06-14 05:21:04 +0000355- Patch #1455898: The MBCS codec now supports the incremental mode for
356 double-byte encodings.
357
Tim Peters43898b42006-06-14 04:09:25 +0000358- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
359 guarantee that adjacent triples in the return list always describe
360 non-adjacent blocks. Previously, a pair of matching blocks could end
361 up being described by multiple adjacent triples that formed a partition
362 of the matching pair.

371
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000372- The wsgiref package has been added to the standard library.
373
Nick Coghlan676725d2006-06-08 13:54:49 +0000374- The functions update_wrapper() and wraps() have been added to the functools
375 module. These make it easier to copy relevant metadata from the original
376 function when writing wrapper functions.
377
Tim Petersd6a9eef2006-06-05 01:48:21 +0000378- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
379 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000380
Martin v. Löwis3f767792006-06-04 19:36:28 +0000381- Patch #1359618: Speed up charmap encoder by using a trie structure
382 for lookup.
383
Tim Petersd609b1a2006-06-02 23:22:51 +0000384- The functions in the ``pprint`` module now sort dictionaries by key
385 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
386 if and only if its display required more than one line, although that
387 wasn't documented. The new behavior increases predictability; e.g.,
388 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

411 stdout arguments, making it possible to redirect input and output
412 for remote debugging.
413
414- Patch #1484695: Update the tarfile module to version 0.8. This fixes
415 a couple of issues, notably handling of long file names using the
416 GNU LONGNAME extension.

461=================================
462
463*Release date: 27-APR-2006*
464
465Core and builtins
466-----------------
467
Thomas Heller1b046642006-04-18 18:51:06 +0000468- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
469 by converting these apis from macros into exported functions again:
470
471 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
472 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
473 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
474 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
475 PyRun_String Py_CompileString
476
Martin v. Löwis45294a92006-04-18 06:24:08 +0000477- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
478
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000479- All uses of PyStructSequence_InitType have been changed to initialize
480 the type objects only once, even if the interpreter is initialized
481 multiple times.
482
Neal Norwitz61546162006-04-14 05:20:28 +0000483- Bug #1454485, array.array('u') could crash the interpreter. This was
484 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
485 to unicode when it didn't make sense. 'u#' now requires a unicode string.
486
487- Py_UNICODE is unsigned. It was always documented as unsigned, but
488 due to a bug had a signed value in previous versions.
489
Tim Peters3a5e8b12006-04-11 01:44:07 +0000490- Patch #837242: ``id()`` of any Python object always gives a positive
491 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
492 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000493 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000494 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000495
Tim Peters3a5e8b12006-04-11 01:44:07 +0000496 def __hash__(self):
497 return id(self) # WRONG
498
499 because a hash result must be a (short) Python int but it was always
500 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000501 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000502 was always usable as a hash value before this patch. That's no longer
503 necessarily so.
504
505- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000506 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000507 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000508 #1454844)
509
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000510- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
511 involving generators that have paused outside of any ``try`` or ``with``
512 blocks. (In 2.5a1, a paused generator that was part of a reference
513 cycle could not be garbage collected, regardless of whether it was
514 paused in a ``try`` or ``with`` block.)

533- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
534 as older versions cause excessive test failures.

Tim Peters711bf302006-04-25 03:31:36 +0000542- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
543 a doctest to be skipped (the code is not run, and the expected output
544 or exception is ignored).
545

Greg Wardab05edc2006-04-23 03:47:58 +0000549- Updated optparse module to Optik 1.5.1 (allow numeric constants in
550 hex, octal, or binary; add ``append_const`` action; keep going if
551 gettext cannot be imported; added ``OptionParser.destroy()`` method;
552 added ``epilog`` for better help generation).
553
Tim Peters21fbd572006-04-21 21:18:10 +0000554- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
555 called from a thread spawned as a side effect of importing a module.
556
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000557- The pydoc module now supports documenting packages contained in
558 .zip or .egg files.
559
560- The pkgutil module now has several new utility functions, such
561 as ``walk_packages()`` to support working with packages that are either
562 in the filesystem or zip files.
563
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000564- The mailbox module can now modify and delete messages from
565 mailboxes, in addition to simply reading them. Thanks to Gregory
566 K. Johnson for writing the code, and to the 2005 Google Summer of
567 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000568
Tim Petersc7605f22006-04-17 21:12:33 +0000569- The ``__del__`` method of class ``local`` in module ``_threading_local``
570 returned before accomplishing any of its intended cleanup.
571

Anthony Baxtere29002c2006-04-12 12:07:31 +0000578- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
579 Windows. Bug #1469163.
580
Phillip J. Eby47032112006-04-11 01:07:43 +0000581- The warnings, linecache, inspect, traceback, site, and doctest modules

606 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000607 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000608 CXX from --with-cxx-main, see description in README.
609

627 it separately and by hand. It also wasn't cleaning up its changes to
628 the current Decimal context.
629
Thomas Woutersabd08882006-04-26 15:53:30 +0000630- regrtest.py now has a -M option to run tests that test the new limits of
631 containers, on 64-bit architectures. Running these tests is only sensible
632 on 64-bit machines with more than two gigabytes of memory. The argument
633 passed is the maximum amount of memory for the tests to use.

642-------------
643
Tim Petersb06d28c2006-05-12 01:57:59 +0000644- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
645
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000646- PEP 343: Added Context Types section to the library reference
647 and attempted to bring other PEP 343 related documentation into
648 line with the implementation and/or python-dev discussions.
649
Tim Peters8dc73d22006-04-24 02:03:16 +0000650- Bug #1337990: clarified that ``doctest`` does not support examples
651 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000659Core and builtins
660-----------------
661
Nick Coghlan43832302006-04-23 17:04:07 +0000662- PEP 338: -m command line switch now delegates to runpy.run_module
663 allowing it to support modules in packages and zipfiles
664
Martin v. Löwisc661b882006-04-20 04:54:23 +0000665- On Windows, .DLL is not an accepted file name extension for
666 extension modules anymore; extensions are only found if they
667 end in .PYD.
668
Martin v. Löwisea62d252006-04-03 10:56:49 +0000669- Bug #1421664: sys.stderr.encoding is now set to the same value as
670 sys.stdout.encoding.
671
Neal Norwitz92e212f2006-04-03 04:48:37 +0000672- __import__ accepts keyword arguments.
673
Georg Brandlccadf842006-03-31 18:54:53 +0000674- Patch #1460496: round() now accepts keyword arguments.
675
Anthony Baxter262c00a2006-03-30 10:53:17 +0000676- Fixed bug #1459029 - unicode reprs were double-escaped.
677
Hye-Shik Changd478f342006-03-23 12:32:36 +0000678- Patch #1396919: The system scope threads are reenabled on FreeBSD
679 5.4 and later versions.
680
Neal Norwitze98ccf62006-03-23 05:39:47 +0000681- Bug #1115379: Compiling a Unicode string with an encoding declaration
682 now gives a SyntaxError.
683
Georg Brandlabd1ff82006-03-18 07:59:59 +0000684- Previously, Python code had no easy way to access the contents of a
685 cell object. Now, a ``cell_contents`` attribute has been added
686 (closes patch #1170323).
687
Tim Peterscf79aac2006-03-16 01:14:46 +0000688- Patch #1123430: Python's small-object allocator now returns an arena to
689 the system ``free()`` when all memory within an arena becomes unused
690 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
691 freed. Some applications will see a drop in virtual memory size now,
692 especially long-running applications that, from time to time, temporarily
693 use a large number of small objects. Note that when Python returns an
694 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000695 platform C library will in turn return that memory to the operating system.
696 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000697 appears to be effective at least on Microsoft C and gcc-based systems.
698 Thanks to Evan Jones for hard work and patience.
699
Georg Brandl533ff6f2006-03-08 18:09:27 +0000700- Patch #1434038: property() now uses the getter's docstring if there is
701 no "doc" argument given. This makes it possible to legitimately use
702 property() as a decorator to produce a read-only property.
703
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000704- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
705 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
706 of requiring an int or long in slicing and a few other contexts, enabling
707 other objects (e.g. Numeric Python's integers) to be used as slice indices.
708
Neal Norwitz995acdf2006-03-07 05:01:00 +0000709- Fixed various bugs reported by Coverity's Prevent tool.
710
Brett Cannonbf364092006-03-01 04:25:17 +0000711- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
712 new exception base class, BaseException, which has a new message attribute.
713 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
714 Raising a string exception now raises a DeprecationWarning.
715
Thomas Woutersfb609f42006-02-28 16:37:25 +0000716- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
717 explicitly relative, using 'from .module import name' to mean 'from the same
718 package as this module is in. Imports without dots still default to the
719 old relative-then-absolute, unless 'from __future__ import
720 absolute_import' is used.
721
Brett Cannona7446e32006-02-27 23:39:10 +0000722- Properly check if 'warnings' raises an exception (usually when a filter set
723 to "error" is triggered) when raising a warning for raising string
724 exceptions.
725
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000726- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000727 The name was removed from Include/code.h.
728
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000729- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000730
Guido van Rossum1968ad32006-02-25 22:38:04 +0000731- Patch 1433928:
732 - The copy module now "copies" function objects (as atomic objects).
733 - dict.__getitem__ now looks for a __missing__ hook before raising
734 KeyError.
735
Tim Peters84ef21c2006-02-28 20:39:06 +0000736- PEP 343: with statement implemented. Needs ``from __future__ import
737 with_statement``. Use of 'with' as a variable will generate a warning.
738 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000739 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000740 The following objects have __context__ methods:
741 - The built-in file type.
742 - The thread.LockType type.
743 - The following types defined by the threading module:
744 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
745 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000746
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000747- Fix the encodings package codec search function to only search
748 inside its own package. Fixes problem reported in patch #1433198.
749
750 Note: Codec packages should implement and register their own
751 codec search function. PEP 100 has the details.
752
Tim Peters9ea89d22006-06-04 03:26:02 +0000753- PEP 353: Using ``Py_ssize_t`` as the index type.
754
755- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
756 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
757 now allow Python to make use of memory blocks exceeding 2**32 bytes for
758 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
759 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000760
Neal Norwitzfc76d632006-01-10 06:03:13 +0000761- Patch #1400181, fix unicode string formatting to not use the locale.
762 This is how string objects work. u'%f' could use , instead of .
763 for the decimal point. Now both strings and unicode always use periods.
764
Neal Norwitz671b9e32006-01-09 07:07:12 +0000765- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
766 configure would break checking curses.h.
767
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000768- Bug #959576: The pwd module is now builtin. This allows Python to be
769 built on UNIX platforms without $HOME set.
770
Neal Norwitzc10978f2005-12-19 06:07:16 +0000771- Bug #1072182, fix some potential problems if characters are signed.
772
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000773- Bug #889500, fix line number on SyntaxWarning for global declarations.
774
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000775- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
776
Neal Norwitze7214a12005-12-18 05:03:17 +0000777- Support for converting hex strings to floats no longer works.
778 This was not portable. float('0x3') now raises a ValueError.
779
Barry Warsaw2a38a862005-12-18 01:27:35 +0000780- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000781 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000782 is now displayed in interactive prompt banner.
783
Georg Brandlfa166682005-12-17 21:45:17 +0000784- Implementation of PEP 341 - Unification of try/except and try/finally.
785 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000786 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000787
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000788- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
789 now encodes backslash correctly.
790
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000791- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
792
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000793- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000794 and long longs.
795
Neal Norwitz67715f02005-11-09 06:59:35 +0000796- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000797 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000798 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000799
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000800- Replaced most Unicode charmap codecs with new ones using the
801 new Unicode translate string feature in the builtin charmap
802 codec; the codecs were created from the mapping tables available
803 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
804 encodings now include a mapping for the Apple logo)
805
Tim Peterse3547fd2005-12-16 23:13:57 +0000806- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000807
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000808- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000809
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000810- A new AST parser implementation was completed. The abstract
811 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000812 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000813
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000814- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000815 The following code now raises a SyntaxError: foo(a = i for i in range(10))
816
Neal Norwitz708e51a2005-10-03 04:48:15 +0000817- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
818
Neal Norwitz11bd1192005-10-03 00:54:56 +0000819- SF Bug #887946: fix segfault when redirecting stdin from a directory.
820 Provide a warning when a directory is passed on the command line.
821
Neal Norwitz40d37812005-10-02 01:48:49 +0000822- Fix segfault with invalid coding.
823
824- SF bug #772896: unknown encoding results in MemoryError.
825
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000826- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000827 supported a __len__() method which evaluated to False when the iterator
828 was empty.
829
Guido van Rossum630db602005-09-20 18:49:54 +0000830- On 64-bit platforms, when __len__() returns a value that cannot be
831 represented as a C int, raise OverflowError.
832
Skip Montanarof8948ca2005-09-19 03:54:46 +0000833- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000834 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000835
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000836- SF bug #893549: parsing keyword arguments was broken with a few format
837 codes.
838
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000839- Changes donated by Elemental Security to make it work on AIX 5.3
840 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
841 bug #105470: test_pwd fails on 64bit system (Opteron).
842
Guido van Rossum539c6622005-09-14 17:49:54 +0000843- Changes donated by Elemental Security to make it work on HP-UX 11 on
844 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
845
Georg Brandl4550b8d2005-08-26 06:43:52 +0000846- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000847 (fixes bug #1119418).
848
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000849- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
850
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000851- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
852 exceptions that cause a function to exit.
853
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000854- The implementation of set() and frozenset() was revised to use its
855 own internal data structure. Memory consumption is reduced by 1/3
856 and there are modest speed-ups as well. The API is unchanged.
857
Tim Petersde7990b2005-07-17 23:45:23 +0000858- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
859
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000860- SF bug #1229429: PyObject_CallMethod failed to decrement some
861 reference counts in some error exit cases.
862
Tim Petersecc6e6a2005-07-10 22:30:55 +0000863- SF bug #1185883: Python's small-object memory allocator took over
864 a block managed by the platform C library whenever a realloc specified
865 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000866 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000867 portable way to copy data from the C-managed block into Python's
868 small-object space without risking a memory fault. Python's small-object
869 realloc now leaves such blocks under the control of the platform C
870 realloc.
871
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000872- SF bug #1232517: An overflow error was not detected properly when
873 attempting to convert a large float to an int in os.utime().
874
Raymond Hettinger3296e692005-06-29 23:29:56 +0000875- SF bug #1224347: hex longs now print with lowercase letters just
876 like their int counterparts.
877
Michael W. Hudson188d4362005-06-20 16:52:57 +0000878- SF bug #1163563: the original fix for bug #1010677 ("thread Module
879 Breaks PyGILState_Ensure()") broke badly in the case of multiple
880 interpreter states; back out that fix and do a better job (see
881 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
882 for a longer write-up of the problem).
883
Michael W. Hudsondf888462005-06-03 14:41:55 +0000884- SF patch #1180995: marshal now uses a binary format by default when
885 serializing floats.
886
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000887- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
888 the routines that promise to produce IEEE 754 binary representations
889 of floats now simply copy bytes around.
890
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000891- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
892 278.
893
Brett Cannonc3647ac2005-04-26 03:45:26 +0000894- patch #1109424: int, long, float, complex, and unicode now check for the
895 proper magic slot for type conversions when subclassed. Previously the
896 magic slot was ignored during conversion. Semantics now match the way
897 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000898 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000899 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000900 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000901
Barry Warsawc8d907c2005-04-19 23:43:40 +0000902- Descriptors defined in C with a PyGetSetDef structure, where the setter is
903 NULL, now raise an AttributeError when attempting to set or delete the
904 attribute. Previously a TypeError was raised, but this was inconsistent
905 with the equivalent pure-Python implementation.
906
Michael W. Hudson774479c2005-04-18 08:46:17 +0000907- It is now safe to call PyGILState_Release() before
908 PyEval_InitThreads() (note that if there is reason to believe there
909 are multiple threads around you still must call PyEval_InitThreads()
910 before using the Python API; this fix is for extension modules that
911 have no way of knowing if Python is multi-threaded yet).
912
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000913- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
914 disabled caused a crash.

918
Tim Petersecc6e6a2005-07-10 22:30:55 +0000919- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000920 fixes the crash seen in bug #1165761
921
Raymond Hettinger96229b12005-03-11 06:49:40 +0000922- Added two new builtins, any() and all().
923
Brett Cannon409d8f22005-03-05 06:47:57 +0000924- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000925 (e.g., ``class C(): pass`` is no longer a syntax error).
926 Patch #1176012 added support to the 'parser' module and 'compiler' package
927 (thanks to logistix for that added support).

938
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000939- Bug #1124295: the __name__ attribute of file objects was
940 inadvertently made inaccessible in restricted mode.
941
Tim Petersecc6e6a2005-07-10 22:30:55 +0000942- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000943 an ferror() call.
944
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000945- min() and max() now support key= arguments with the same meaning as in

954 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000955
Jeremy Hyltonab630502005-02-04 18:44:06 +0000956- The parser did not complain about future statements in illegal
957 positions. It once again reports a syntax error if a future
958 statement occurs after anything other than a doc string.
959
Neil Schemenauercf52c072005-08-12 17:34:58 +0000960- Change the %s format specifier for str objects so that it returns a
961 unicode instance if the argument is not an instance of basestring and
962 calling __str__ on the argument returns a unicode instance.
963
Tim Petersf4e69282006-02-27 17:15:31 +0000964- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
965 current thread state when the auto-GIL-state machinery knows about
966 it (since the thread state is being deleted, continuing to remember it
967 can't help, but can hurt if another thread happens to get created with
968 the same thread id).

Anthony Baxterc51ee692006-04-01 00:57:31 +00001174- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001175 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001176 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001177 module will not be built.
1178
Tim Petersc17976e2006-04-01 00:26:53 +00001179- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1180 aren't officially supported here, and trying to use them will probably
1181 raise an exception some day. But dicts have been allowed, and "mostly
1182 worked", so support for them won't go away without warning.
1183
Georg Brandl338ef7d2006-03-31 18:42:16 +00001184- Bug #1445068: getpass.getpass() can now be given an explicit stream
1185 argument to specify where to write the prompt.
1186
Georg Brandl22ec80b2006-03-31 18:25:44 +00001187- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1193 key to be used for signing the uploaded code.
1194
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001195- Queue.Queue objects now support .task_done() and .join() methods
1196 to make it easier to monitor when daemon threads have completed
1197 processing all enqueued tasks. Patch #1455676.
1198
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001199- popen2.Popen objects now preserve the command in a .cmd attribute.
1200

1202
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001203- email 4.0 package now integrated. This is largely the same as the email 3.0
1204 package that was included in Python 2.3, except that PEP 8 module names are
1205 now used (e.g. mail.message instead of email.Message). The MIME classes
1206 have been moved to a subpackage (e.g. email.mime.text instead of
1207 email.MIMEText). The old names are still supported for now. Several
1208 deprecated Message methods have been removed and lots of bugs have been
1209 fixed. More details can be found in the email package documentation.
1210
Walter Dörwald40108c92006-03-27 08:15:44 +00001211- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1212 (a subclass of tuple) that provides incremental decoders and encoders
1213 (a way to use stateful codecs without the stream API). Python functions
1214 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1215 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1216 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001217
Walter Dörwald067db482006-03-15 22:17:27 +00001218- Patch #1359365: Calling next() on a closed StringIO.String object raises
1219 a ValueError instead of a StopIteration now (like file and cString.String do).
1220 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1221 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001222
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001223- A regrtest option -w was added to re-run failed tests in verbose mode.

1291 LoadError as documented, instead of IOError. For compatibility,
1292 LoadError subclasses IOError.
1293

Tim Peterse3547fd2005-12-16 23:13:57 +00001295 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1296 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1297 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1298 Ronald L. Rivest offered this advice for Python:
1299
1300 "The consensus of researchers in this area (at least as
1301 expressed at the NIST Hash Function Workshop 10/31/05),
1302 is that SHA-256 is a good choice for the time being, but
1303 that research should continue, and other alternatives may
1304 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001305
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001306- Added a subset of Fredrik Lundh's ElementTree package. Available

1410
Skip Montanaro174dd222005-05-14 20:54:16 +00001411- Patch #1120353: The xmlrpclib module provides better, more transparent,

1456
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001457- Patch #1104111: Alter setup.py --help and --help-commands.
1458
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001459- Patch #1121234: Properly cleanup _exit and tkerror commands.
1460
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001461- Patch #1049151: xdrlib now unpacks booleans as True or False.
1462
Raymond Hettingerbab41432005-02-05 01:31:19 +00001463- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1464
Guido van Rossumd0641422005-02-03 15:01:24 +00001465- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1466 disables recursive traversal through instance attributes, which can
1467 be exploited in various ways.
1468
Tim Peterse3547fd2005-12-16 23:13:57 +00001469- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001470 flags on the HTTP listening socket.
1471
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001472- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1473 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1474
Tim Peterse3547fd2005-12-16 23:13:57 +00001475- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001476 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1477
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001478- Bug #1110478: Revert os.environ.update to do putenv again.
1479
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001480- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1481
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001482- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1483
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001484- Enhancements to the csv module:
1485
1486 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001487 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001488 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001489 + Dialect parameter parsing has been re-implemented to improve error
1490 reporting.
1491 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1492 dictates.
1493 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001494 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001495 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001496 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1497 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001498 + reader now allows \r characters to be quoted (previously it only allowed
1499 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001500 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001501 + Dialect classes passed to the module are no longer instantiated by
1502 the module before being parsed (the former validation scheme required
1503 this, but the mechanism was unreliable).
1504 + The dialect registry now contains instances of the internal
1505 C-coded dialect type, rather than references to python objects.
1506 + the internal c-coded dialect type is now immutable.
1507 + register_dialect now accepts the same keyword dialect specifications
1508 as the reader and writer, allowing the user to register dialects
1509 without first creating a dialect class.
1510 + a configurable limit to the size of parsed fields has been added -
1511 previously, an unmatched quote character could result in the entire
1512 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001513 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001514 the parser field size limit (returning the former limit). The initial
1515 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001516 + A line_num attribute has been added to the reader object, which tracks
1517 the number of lines read from the source iterator. This is not
1518 the same as the number of records returned, as records can span
1519 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001520 + reader and writer objects were not being registered with the cyclic-GC.
1521 This has been fixed.
1522
Brett Cannone6539c42005-01-08 02:43:53 +00001523- _DummyThread objects in the threading module now delete self.__block that is
1524 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1525 lock primitives tend to be limited in number and thus should not be wasted on
1526 a _DummyThread object. Fixes bug #1089632.
1527
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001528- The imghdr module now detects Exif files.
1529
Raymond Hettinger6065d322004-12-20 23:51:53 +00001530- StringIO.truncate() now correctly adjusts the size attribute.
1531 (Bug #951915).
1532
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001533- locale.py now uses an updated locale alias table (built using
1534 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1535 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001536 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001537
Raymond Hettinger3557f422004-12-07 12:02:02 +00001538- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1539
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001540- the pickle module no longer accepts the deprecated None option in the
1541 args tuple returned by __reduce__().
1542
Brett Cannon84667c02004-12-07 03:25:18 +00001543- optparse now optionally imports gettext. This allows its use in setup.py.
1544
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001545- the pickle module no longer uses the deprecated bin parameter.
1546
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001547- the shelve module no longer uses the deprecated binary parameter.
1548
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001549- the pstats module no longer uses the deprecated ignore() method.
1550
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001551- the filecmp module no longer uses the deprecated use_statcache argument.
1552
Raymond Hettinger664347b2004-12-04 21:21:53 +00001553- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1554 extended or overridden by subclasses. Formerly, the subclassed method would
1555 be ignored by the rest of the module. (Bug #1078905).
1556
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001557- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001558 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001559
Walter Dörwald36733692004-12-22 12:50:50 +00001560- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1561 once when a size argument is given. This prevents a buffer overflow in the
1562 tokenizer with very long source lines.
1563
Barry Warsaw538561e2006-01-01 21:48:54 +00001564- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1565 immediately after creating the object, without any intervening
1566 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001567
Skip Montanaro05885812005-01-16 20:48:27 +00001568- The reconvert.quote function can now emit triple-quoted strings. The
1569 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001570
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001571- ``UserString.MutableString`` now supports negative indices in
1572 ``__setitem__`` and ``__delitem__``
1573
Greg Ward40407942005-03-05 02:53:17 +00001574- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1575 correctly.
1576
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001577- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1578 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1579 character even if the user has passed a size parameter to get a proper
1580 line ending. Remove the special handling of a "\r\n" that has been split
1581 between two lines.
1582
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001583- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1584 about illegal code points. The codec now supports PEP 293 style error
1585 handlers.
1586
Walter Dörwald78a78b02005-09-01 12:04:29 +00001587- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001588 from the input stream, so that the output is a byte string in the correct
1589 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001590
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001591- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1592 considering it exactly like a '*'.
1593
Walter Dörwald007f8df2005-10-09 19:42:27 +00001594- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1595 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001596
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001597- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1598
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001599- Patch #1413711: Certain patterns of differences were making difflib
1600 touch the recursion limit.
1601
Walter Dörwald58917a62006-03-31 15:26:22 +00001602- Bug #947906: An object oriented interface has been added to the calendar
1603 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001604 called as a script (e.g. via ``python -mcalendar``). Localized month and
1605 weekday names can be ouput (even if an exotic encoding is used) using
1606 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001607
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001608Build
1609-----
1610
Neal Norwitz602d3392006-03-31 08:21:40 +00001611- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1612 by using -mieee gcc option.
1613
Martin v. Löwis86d66262006-02-17 08:40:11 +00001614- Patch #1432345: Make python compile on DragonFly.
1615
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001616- Build support for Win64-AMD64 was added.
1617
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001618- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1619
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001620- Patch #881820: look for openpty and forkpty also in libbsd.
1621
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001622- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1623 The zlib module is now builtin on Windows.
1624
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001625- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1626
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001627- Bug #1189330: configure did not correctly determine the necessary
1628 value of LINKCC if python was built with GCC 4.0.
1629
Trent Mick8321b422005-07-26 02:29:21 +00001630- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1631 vulnerability in zlib 1.2.1 and 1.2.2.
1632
Brett Cannon08cd5982005-04-24 22:26:38 +00001633- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1634 flags that change binary compatibility. Changes were also made to
1635 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001636 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001637
Bob Ippolitoed233462005-03-29 13:47:59 +00001638- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1639 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1640 no longer exists). This configure patch makes things right.
1641
Martin v. Löwise2713be2005-03-08 15:03:08 +00001642- Bug #1158607: Build with --disable-unicode again.
1643
Brett Cannon46d96232005-02-16 00:07:19 +00001644- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1645 defined. Discovered as a result of not being able to build on OS X.
1646
Brett Cannon516592f2004-12-07 00:42:59 +00001647- setup.py now uses the directories specified in LDFLAGS using the -L option
1648 and in CPPFLAGS using the -I option for adding library and include
1649 directories, respectively, for compiling extension modules against. This has
1650 led to the core being compiled using the values in CPPFLAGS. It also removes
1651 the need for the special-casing of both DarwinPorts and Fink for darwin since
1652 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1653 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1654 Fink, ``-I/opt/local/include`` for DarwinPorts).
1655
Brett Cannon43802422005-02-10 20:48:03 +00001656- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1657 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1658 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1659 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001661C API
1662-----
1663
Tim Petersc9d78aa2006-03-26 23:27:58 +00001664- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1665 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1666 is obtained via the ``PyObject_`` family, it must be released via the
1667 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1668 always been officially true, but when Python's small-object allocator was
1669 introduced, an attempt was made to cater to a few extension modules
1670 discovered at the time that obtained memory via ``PyObject_New`` but
1671 released it via ``PyMem_DEL``. It's years later, and if such code still
1672 exists it will fail now (probably with segfaults, but calling wrong
1673 low-level memory management functions can yield many symptoms).
1674
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001675- Added a C API for set and frozenset objects.
1676
Raymond Hettinger66517482004-12-03 11:45:13 +00001677- Removed PyRange_New().
1678
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001679- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1680 mapping argument now. This string is used as a mapping table. Byte values
1681 greater than the length of the string and 0xFFFE are treated as undefined
1682 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001690- Patch #1276356: New resource "urlfetch" is implemented. This enables
