11
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.

40-------
41
Martin v. Löwis388a8c22006-07-06 19:28:03 +000042- Bug #1515998: Properly generate logical ids for files in bdist_msi.
43
Nick Coghlan2d792252006-07-06 13:47:18 +000044- warnings.py now ignores ImportWarning by default
45
Thomas Heller5becdbe2006-07-06 08:48:35 +000046- Patch #1517790: It is now possible to use custom objects in the ctypes
47 foreign function argtypes sequence as long as they provide a from_param
48 method, no longer is it required that the object is a ctypes type.
49
Thomas Woutersadd19112006-07-05 11:03:49 +000050- string.Template() now correctly handles tuple-values. Previously,
51 multi-value tuples would raise an exception and single-value tuples would
52 be treated as the value they contain, instead.
53
Martin v. Löwisede77f52006-07-03 13:01:35 +000054- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

61 degrees and radians.
62
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000063- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +000064 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000065
Martin v. Löwisbd39c032006-07-03 09:44:00 +000066- Bug #1514703: Only setup canvas window in turtle when the canvas
67 is created.
68
Martin v. Löwis7596e832006-07-01 15:33:37 +000069- Bug #1513223: .close() of a _socketobj now releases the underlying
70 socket again, which then gets closed as it becomes unreferenced.
71
Thomas Hellerbde08132006-06-29 18:34:15 +000072- The '_ctypes' extension module now works when Python is configured
73 with the --without-threads option.
74
Fred Drake10497c82006-06-29 02:57:48 +000075- Bug #1504333: Make sgmllib support angle brackets in quoted
76 attribute values.
77
78- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
79 sgmllib ('[' and ']' were not accepted).
80
Georg Brandl1be63af2006-06-28 20:23:25 +000081- Fix a bug in the turtle module's end_fill function.
82
Brett Cannon53ab5b72006-06-22 16:49:14 +000083- Bug #1510580: The 'warnings' module improperly required that a Warning
84 category be either a types.ClassType and a subclass of Warning. The proper
85 check is just that it is a subclass with Warning as the documentation states.
86
Georg Brandlad29e632006-06-21 17:45:17 +000087- The compiler module now correctly compiles the new try-except-finally
88 statement (bug #1509132).
89
Neal Norwitz60373cd2006-06-22 06:30:50 +000090- The wsgiref package is now installed properly on Unix.
91
Vinay Sajip28e57612006-07-01 10:45:20 +000092- A bug was fixed in logging.config.fileConfig() which caused a crash on
93 shutdown when fileConfig() was called multiple times.
94
Gerhard Häring762fbd32006-07-02 17:48:30 +000095- The sqlite3 module did cut off data from the SQLite database at the first
96 null character before sending it to a custom converter. This has been fixed
97 now.
98
Neal Norwitz0f8b31a2006-06-28 06:28:31 +000099Extension Modules
100-----------------
101
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000102- Bug #1513646: os.access on Windows now correctly determines write
103 access, again.
104
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000105- Bug #1512695: cPickle.loads could crash if it was interrupted with
106 a KeyboardInterrupt.
107
Neal Norwitza12aa882006-07-06 06:45:08 +0000108- Bug #1296433: parsing XML with a non-default encoding and
109 a CharacterDataHandler could crash the interpreter in pyexpat.
110
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000111- Patch #1516912: improve Modules support for OpenVMS.

114-----
115
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000116- 'configure' now detects the zlib library the same way as distutils.
117 Previously, the slight difference could cause compilation errors of the
118 'zlib' module on systems with more than one version of zlib.
119
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000120- The MSI compileall step was fixed to also support a TARGETDIR
121 with spaces in it.
122
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000123- Bug #1517388: sqlite3.dll is now installed on Windows independent
124 of Tcl/Tk.
125
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000126- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000127 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000128
Neal Norwitzb15ac312006-06-29 04:10:08 +0000129Tests
130-----
131
132- Call os.waitpid() at the end of tests that spawn child processes in order
133 to minimize resources (zombies).

136-------------
137
Nick Coghlan2d792252006-07-06 13:47:18 +0000138- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
139 documentation for the warnings module.
140
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000141- Patch #1509163: MS Toolkit Compiler no longer available.
142

Nick Coghlanc649ec52006-05-29 12:43:05 +0000145What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000146================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000147
Anthony Baxterd1136802006-06-19 12:04:15 +0000148*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000149
150Core and builtins
151-----------------
152
Georg Brandla56b9152006-06-19 06:35:54 +0000153- Patch #1507676: Error messages returned by invalid abstract object operations
154 (such as iterating over an integer) have been improved and now include the
155 type of the offending object to help with debugging.
156
Brett Cannonea3912b2006-06-13 21:46:41 +0000157- Bug #992017: A classic class that defined a __coerce__() method that returned
158 its arguments swapped would infinitely recurse and segfault the interpreter.
159
Neal Norwitz909eb122006-06-12 02:13:21 +0000160- Fix the socket tests so they can be run concurrently.
161
Neal Norwitzb9845e72006-06-12 02:11:18 +0000162- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000163 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000164
Brett Cannon22565aa2006-06-09 22:31:23 +0000165- Bug #532646: object.__call__() will continue looking for the __call__
166 attribute on objects until one without one is found. This leads to recursion
167 when you take a class and set its __call__ attribute to an instance of the
168 class. Originally fixed for classic classes, but this fix is for new-style.
169 Removes the infinite_rec_3 crasher.
170
Georg Brandl24250812006-06-09 18:45:48 +0000171- The string and unicode methods startswith() and endswith() now accept
172 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
173
Brett Cannonde3b0522006-06-08 17:00:45 +0000174- Buffer objects, at the C level, never used the char buffer
175 implementation even when the char buffer for the wrapped object was
176 explicitly requested (originally returned the read or write buffer).
177 Now a TypeError is raised if the char buffer is not present but is
178 requested.
179
Georg Brandlddbaa662006-06-04 21:56:52 +0000180- Patch #1346214: Statements like "if 0: suite" are now again optimized
181 away like they were in Python 2.4.
182
Georg Brandlb7c8f542006-05-27 12:30:25 +0000183- Builtin exceptions are now full-blown new-style classes instead of
184 instances pretending to be classes, which speeds up exception handling
185 by about 80% in comparison to 2.5a2.
186
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000187- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
188 Unicode 4.1.
189
Georg Brandlf4ef1162006-05-26 18:03:31 +0000190- Patch #921466: sys.path_importer_cache is now used to cache valid and
191 invalid file paths for the built-in import machinery which leads to
192 fewer open calls on startup.
193
Tim Peters696cf432006-05-24 21:10:40 +0000194- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
195 of-2 bases. The largest speedup is for inputs with about 1000 decimal
196 digits. Conversion from non-power-of-2 bases remains quadratic-time in
197 the number of input digits (it was and remains linear-time for bases
198 2, 4, 8, 16 and 32).
199
Tim Petersb713ec22006-05-23 18:45:30 +0000200- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
201 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
202 an integer close to ``sys.maxint``. This was repaired by patch
203 #1335972, which also gives a nice speedup.
204
Richard Jonescebbefc2006-05-23 18:28:17 +0000205- Patch #1337051: reduced size of frame objects.
206
207- PyErr_NewException now accepts a tuple of base classes as its
208 "base" parameter.
209
Richard Jones7c88dcc2006-05-23 10:37:38 +0000210- Patch #876206: function call speedup by retaining allocated frame
211 objects.
212
Georg Brandl7b90e162006-05-18 07:01:27 +0000213- Bug #1462152: file() now checks more thoroughly for invalid mode
214 strings and removes a possible "U" before passing the mode to the
215 C library function.
216
Neal Norwitz1004a532006-05-15 07:17:23 +0000217- Patch #1488312, Fix memory alignment problem on SPARC in unicode
218
Neal Norwitz373f0a72006-05-15 07:04:36 +0000219- Bug #1487966: Fix SystemError with conditional expression in assignment
220
Martin v. Löwis879768d2006-05-11 13:28:43 +0000221- WindowsError now has two error code attributes: errno, which carries
222 the error values from errno.h, and winerror, which carries the error
223 values from winerror.h. Previous versions put the winerror.h values
224 (from GetLastError()) into the errno attribute.
225
Martin v. Löwis77736712006-05-04 05:51:03 +0000226- Patch #1475845: Raise IndentationError for unexpected indent.
227
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000228- Patch #1479181: split open() and file() from being aliases for each other.
229
Tim Peters44bd9862006-06-01 13:49:23 +0000230- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
231 methods were always silently ignored by dictionaries when comparing keys.
232 They are now passed through (except when using the C API function
233 ``PyDict_GetItem()``, whose semantics did not change).
234
235- Bug #1456209: In some obscure cases it was possible for a class with a
236 custom ``__eq__()`` method to confuse dict internals when class instances
237 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
238 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000240Extension Modules
241-----------------
242
Trent Mick960a3f82006-06-28 20:30:41 +0000243- Bug #1295808: expat symbols should be namespaced in pyexpat
244
245- Patch #1462338: Upgrade pyexpat to expat 2.0.0
246
Brett Cannon6ee7d012006-06-08 16:23:04 +0000247- Change binascii.hexlify to accept a read-only buffer instead of only a char
248 buffer and actually follow its documentation.
249
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000250- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
251
Nick Coghlanc649ec52006-05-29 12:43:05 +0000252- Patch #1478788 (modified version): The functional extension module has
253 been renamed to _functools and a functools Python wrapper module added.
254 This provides a home for additional function related utilities that are
255 not specifically about functional programming. See PEP 309.
256
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000257- Patch #1493701: performance enhancements for struct module.
258
Georg Brandl378d5922006-05-17 14:26:50 +0000259- Patch #1490224: time.altzone is now set correctly on Cygwin.
260
Georg Brandl8d3342b2006-05-16 07:38:27 +0000261- Patch #1435422: zlib's compress and decompress objects now have a
262 copy() method.
263
Andrew MacIntyre92913322006-06-13 15:04:24 +0000264- Patch #1454481: thread stack size is now tunable at runtime for thread
265 enabled builds on Windows and systems with Posix threads support.
266
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000267- On Win32, os.listdir now supports arbitrarily-long Unicode path names
268 (up to the system limit of 32K characters).
269
270- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
271 As a result, these functions now raise WindowsError instead of OSError.
272
Tim Peters7a822da2006-05-25 21:50:17 +0000273- ``time.clock()`` on Win64 should use the high-performance Windows
274 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
275 Windows platforms).
276
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000277- Calling Tk_Init twice is refused if the first call failed as that
278 may deadlock.
279
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000280- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
281 accept it without potentially using an uninitialized pointer.
282
283- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
284 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
285 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000286
Gregory P. Smith372b5832006-06-05 18:48:21 +0000287- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000288 [pybsddb project SF patch number 1466734]
289
Gregory P. Smith372b5832006-06-05 18:48:21 +0000290- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
291 parameter is supplied. [SF pybsddb bug #1477863]
292
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000293- bsddb: the __len__ method of a DB object has been fixed to return correct
294 results. It could previously incorrectly return 0 in some cases.
295 Fixes SF bug 1493322 (pybsddb bug 1184012).
296
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000297- bsddb: the bsddb.dbtables Modify method now raises the proper error and
298 aborts the db transaction safely when a modifier callback fails.
299 Fixes SF python patch/bug #1408584.
300
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000301- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000302 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000303 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
304 database calls that would previously deadlock. [SF python bug #775414]
305

328 mime.types file for determining MIME types.
329
Georg Brandl2605ca82006-06-14 06:08:31 +0000330- Bug #1339007: Shelf objects now don't raise an exception in their
331 __del__ method when initialization failed.
332
Martin v. Löwisd8251432006-06-14 05:21:04 +0000333- Patch #1455898: The MBCS codec now supports the incremental mode for
334 double-byte encodings.
335
Tim Peters43898b42006-06-14 04:09:25 +0000336- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
337 guarantee that adjacent triples in the return list always describe
338 non-adjacent blocks. Previously, a pair of matching blocks could end
339 up being described by multiple adjacent triples that formed a partition
340 of the matching pair.
341
Greg Ward0e0c9f42006-06-11 16:24:11 +0000342- Bug #1498146: fix optparse to handle Unicode strings in option help,
343 description, and epilog.
344
Greg Wardd1c797e2006-06-11 14:42:41 +0000345- Bug #1366250: minor optparse documentation error.

Greg Ward7f547402006-06-11 00:40:49 +0000347- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
348 clarify docs.
349
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000350- The wsgiref package has been added to the standard library.
351
Nick Coghlan676725d2006-06-08 13:54:49 +0000352- The functions update_wrapper() and wraps() have been added to the functools
353 module. These make it easier to copy relevant metadata from the original
354 function when writing wrapper functions.
355
Tim Petersd6a9eef2006-06-05 01:48:21 +0000356- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
357 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000358
Martin v. Löwis3f767792006-06-04 19:36:28 +0000359- Patch #1359618: Speed up charmap encoder by using a trie structure
360 for lookup.
361
Tim Petersd609b1a2006-06-02 23:22:51 +0000362- The functions in the ``pprint`` module now sort dictionaries by key
363 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
364 if and only if its display required more than one line, although that
365 wasn't documented. The new behavior increases predictability; e.g.,
366 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
367
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000368- Patch #1497027: try HTTP digest auth before basic auth in urllib2

379 format_string() to get the effect of "format % items" but locale-aware,
380 and currency() to format a monetary number with currency sign.
381
Georg Brandle3a25832006-05-17 14:56:04 +0000382- Patch #1486962: Several bugs in the turtle Tk demo module were fixed

386 tarfiles.
387
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000388- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
389 stdout arguments, making it possible to redirect input and output
390 for remote debugging.
391
392- Patch #1484695: Update the tarfile module to version 0.8. This fixes
393 a couple of issues, notably handling of long file names using the
394 GNU LONGNAME extension.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000438What's New in Python 2.5 alpha 2?
439=================================
440
441*Release date: 27-APR-2006*
442
443Core and builtins
444-----------------
445
Thomas Heller1b046642006-04-18 18:51:06 +0000446- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
447 by converting these apis from macros into exported functions again:
448
449 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
450 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
451 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
452 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
453 PyRun_String Py_CompileString
454
Martin v. Löwis45294a92006-04-18 06:24:08 +0000455- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
456
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000457- All uses of PyStructSequence_InitType have been changed to initialize
458 the type objects only once, even if the interpreter is initialized
459 multiple times.
460
Neal Norwitz61546162006-04-14 05:20:28 +0000461- Bug #1454485, array.array('u') could crash the interpreter. This was
462 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
463 to unicode when it didn't make sense. 'u#' now requires a unicode string.
464
465- Py_UNICODE is unsigned. It was always documented as unsigned, but
466 due to a bug had a signed value in previous versions.
467
Tim Peters3a5e8b12006-04-11 01:44:07 +0000468- Patch #837242: ``id()`` of any Python object always gives a positive
469 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
470 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000471 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000472 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000473
Tim Peters3a5e8b12006-04-11 01:44:07 +0000474 def __hash__(self):
475 return id(self) # WRONG
476
477 because a hash result must be a (short) Python int but it was always
478 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000479 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000480 was always usable as a hash value before this patch. That's no longer
481 necessarily so.
482
483- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000484 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000485 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000486 #1454844)
487
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000488- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
489 involving generators that have paused outside of any ``try`` or ``with``
490 blocks. (In 2.5a1, a paused generator that was part of a reference
491 cycle could not be garbage collected, regardless of whether it was
492 paused in a ``try`` or ``with`` block.)

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

Tim Peters711bf302006-04-25 03:31:36 +0000520- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
521 a doctest to be skipped (the code is not run, and the expected output
522 or exception is ignored).
523
Nick Coghlanda2268f2006-04-24 04:37:15 +0000524- Fixed contextlib.nested to cope with exceptions being raised and
525 caught inside exit handlers.
526
Greg Wardab05edc2006-04-23 03:47:58 +0000527- Updated optparse module to Optik 1.5.1 (allow numeric constants in
528 hex, octal, or binary; add ``append_const`` action; keep going if
529 gettext cannot be imported; added ``OptionParser.destroy()`` method;
530 added ``epilog`` for better help generation).
531
Tim Peters21fbd572006-04-21 21:18:10 +0000532- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
533 called from a thread spawned as a side effect of importing a module.
534
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000535- The pydoc module now supports documenting packages contained in
536 .zip or .egg files.
537
538- The pkgutil module now has several new utility functions, such
539 as ``walk_packages()`` to support working with packages that are either
540 in the filesystem or zip files.
541
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000542- The mailbox module can now modify and delete messages from
543 mailboxes, in addition to simply reading them. Thanks to Gregory
544 K. Johnson for writing the code, and to the 2005 Google Summer of
545 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000546
Tim Petersc7605f22006-04-17 21:12:33 +0000547- The ``__del__`` method of class ``local`` in module ``_threading_local``
548 returned before accomplishing any of its intended cleanup.
549
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000550- Patch #790710: Add breakpoint command lists in pdb.

Anthony Baxtere29002c2006-04-12 12:07:31 +0000556- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
557 Windows. Bug #1469163.
558
Phillip J. Eby47032112006-04-11 01:07:43 +0000559- The warnings, linecache, inspect, traceback, site, and doctest modules
560 were updated to work correctly with modules imported from zipfiles or

584 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000585 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000586 CXX from --with-cxx-main, see description in README.
587

603
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000604- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
605 it separately and by hand. It also wasn't cleaning up its changes to
606 the current Decimal context.
607
Thomas Woutersabd08882006-04-26 15:53:30 +0000608- regrtest.py now has a -M option to run tests that test the new limits of
609 containers, on 64-bit architectures. Running these tests is only sensible
610 on 64-bit machines with more than two gigabytes of memory. The argument
611 passed is the maximum amount of memory for the tests to use.

626 line with the implementation and/or python-dev discussions.
627
Tim Peters8dc73d22006-04-24 02:03:16 +0000628- Bug #1337990: clarified that ``doctest`` does not support examples
629 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000632What's New in Python 2.5 alpha 1?
633=================================
634
Anthony Baxterebed3f62006-04-03 15:03:44 +0000635*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000636
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000637Core and builtins
638-----------------
639
Nick Coghlan43832302006-04-23 17:04:07 +0000640- PEP 338: -m command line switch now delegates to runpy.run_module
641 allowing it to support modules in packages and zipfiles
642
Martin v. Löwisc661b882006-04-20 04:54:23 +0000643- On Windows, .DLL is not an accepted file name extension for
644 extension modules anymore; extensions are only found if they
645 end in .PYD.
646
Martin v. Löwisea62d252006-04-03 10:56:49 +0000647- Bug #1421664: sys.stderr.encoding is now set to the same value as
648 sys.stdout.encoding.
649
Neal Norwitz92e212f2006-04-03 04:48:37 +0000650- __import__ accepts keyword arguments.
651
Georg Brandlccadf842006-03-31 18:54:53 +0000652- Patch #1460496: round() now accepts keyword arguments.
653
Anthony Baxter262c00a2006-03-30 10:53:17 +0000654- Fixed bug #1459029 - unicode reprs were double-escaped.
655
Hye-Shik Changd478f342006-03-23 12:32:36 +0000656- Patch #1396919: The system scope threads are reenabled on FreeBSD
657 5.4 and later versions.
658
Neal Norwitze98ccf62006-03-23 05:39:47 +0000659- Bug #1115379: Compiling a Unicode string with an encoding declaration
660 now gives a SyntaxError.
661
Georg Brandlabd1ff82006-03-18 07:59:59 +0000662- Previously, Python code had no easy way to access the contents of a
663 cell object. Now, a ``cell_contents`` attribute has been added
664 (closes patch #1170323).
665
Tim Peterscf79aac2006-03-16 01:14:46 +0000666- Patch #1123430: Python's small-object allocator now returns an arena to
667 the system ``free()`` when all memory within an arena becomes unused
668 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
669 freed. Some applications will see a drop in virtual memory size now,
670 especially long-running applications that, from time to time, temporarily
671 use a large number of small objects. Note that when Python returns an
672 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000673 platform C library will in turn return that memory to the operating system.
674 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000675 appears to be effective at least on Microsoft C and gcc-based systems.
676 Thanks to Evan Jones for hard work and patience.
677
Georg Brandl533ff6f2006-03-08 18:09:27 +0000678- Patch #1434038: property() now uses the getter's docstring if there is
679 no "doc" argument given. This makes it possible to legitimately use
680 property() as a decorator to produce a read-only property.
681
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000682- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
683 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
684 of requiring an int or long in slicing and a few other contexts, enabling
685 other objects (e.g. Numeric Python's integers) to be used as slice indices.
686
Neal Norwitz995acdf2006-03-07 05:01:00 +0000687- Fixed various bugs reported by Coverity's Prevent tool.
688
Brett Cannonbf364092006-03-01 04:25:17 +0000689- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
690 new exception base class, BaseException, which has a new message attribute.
691 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
692 Raising a string exception now raises a DeprecationWarning.
693
Thomas Woutersfb609f42006-02-28 16:37:25 +0000694- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
695 explicitly relative, using 'from .module import name' to mean 'from the same
696 package as this module is in. Imports without dots still default to the
697 old relative-then-absolute, unless 'from __future__ import
698 absolute_import' is used.
699
Brett Cannona7446e32006-02-27 23:39:10 +0000700- Properly check if 'warnings' raises an exception (usually when a filter set
701 to "error" is triggered) when raising a warning for raising string
702 exceptions.
703
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000704- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000705 The name was removed from Include/code.h.
706
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000707- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000708
Guido van Rossum1968ad32006-02-25 22:38:04 +0000709- Patch 1433928:
710 - The copy module now "copies" function objects (as atomic objects).
711 - dict.__getitem__ now looks for a __missing__ hook before raising
712 KeyError.
713
Tim Peters84ef21c2006-02-28 20:39:06 +0000714- PEP 343: with statement implemented. Needs ``from __future__ import
715 with_statement``. Use of 'with' as a variable will generate a warning.
716 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000717 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000718 The following objects have __context__ methods:
719 - The built-in file type.
720 - The thread.LockType type.
721 - The following types defined by the threading module:
722 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
723 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000724
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000725- Fix the encodings package codec search function to only search
726 inside its own package. Fixes problem reported in patch #1433198.
727
728 Note: Codec packages should implement and register their own
729 codec search function. PEP 100 has the details.
730
Tim Peters9ea89d22006-06-04 03:26:02 +0000731- PEP 353: Using ``Py_ssize_t`` as the index type.
732
733- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
734 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
735 now allow Python to make use of memory blocks exceeding 2**32 bytes for
736 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
737 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000738
Neal Norwitzfc76d632006-01-10 06:03:13 +0000739- Patch #1400181, fix unicode string formatting to not use the locale.
740 This is how string objects work. u'%f' could use , instead of .
741 for the decimal point. Now both strings and unicode always use periods.
742
Neal Norwitz671b9e32006-01-09 07:07:12 +0000743- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
744 configure would break checking curses.h.
745
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000746- Bug #959576: The pwd module is now builtin. This allows Python to be
747 built on UNIX platforms without $HOME set.
748
Neal Norwitzc10978f2005-12-19 06:07:16 +0000749- Bug #1072182, fix some potential problems if characters are signed.
750
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000751- Bug #889500, fix line number on SyntaxWarning for global declarations.
752
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000753- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
754
Neal Norwitze7214a12005-12-18 05:03:17 +0000755- Support for converting hex strings to floats no longer works.
756 This was not portable. float('0x3') now raises a ValueError.
757
Barry Warsaw2a38a862005-12-18 01:27:35 +0000758- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000759 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000760 is now displayed in interactive prompt banner.
761
Georg Brandlfa166682005-12-17 21:45:17 +0000762- Implementation of PEP 341 - Unification of try/except and try/finally.
763 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000764 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000765
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000766- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
767 now encodes backslash correctly.
768
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000769- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
770
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000771- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000772 and long longs.
773
Neal Norwitz67715f02005-11-09 06:59:35 +0000774- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000775 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000776 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000777
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000778- Replaced most Unicode charmap codecs with new ones using the
779 new Unicode translate string feature in the builtin charmap
780 codec; the codecs were created from the mapping tables available
781 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
782 encodings now include a mapping for the Apple logo)
783
Tim Peterse3547fd2005-12-16 23:13:57 +0000784- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000785
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000786- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000787
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000788- A new AST parser implementation was completed. The abstract
789 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000790 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000791
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000792- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000793 The following code now raises a SyntaxError: foo(a = i for i in range(10))
794
Neal Norwitz708e51a2005-10-03 04:48:15 +0000795- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
796
Neal Norwitz11bd1192005-10-03 00:54:56 +0000797- SF Bug #887946: fix segfault when redirecting stdin from a directory.
798 Provide a warning when a directory is passed on the command line.
799
Neal Norwitz40d37812005-10-02 01:48:49 +0000800- Fix segfault with invalid coding.
801
802- SF bug #772896: unknown encoding results in MemoryError.
803
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000804- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000805 supported a __len__() method which evaluated to False when the iterator
806 was empty.
807
Guido van Rossum630db602005-09-20 18:49:54 +0000808- On 64-bit platforms, when __len__() returns a value that cannot be
809 represented as a C int, raise OverflowError.
810
Skip Montanarof8948ca2005-09-19 03:54:46 +0000811- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000812 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000813
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000814- SF bug #893549: parsing keyword arguments was broken with a few format
815 codes.
816
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000817- Changes donated by Elemental Security to make it work on AIX 5.3
818 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
819 bug #105470: test_pwd fails on 64bit system (Opteron).
820
Guido van Rossum539c6622005-09-14 17:49:54 +0000821- Changes donated by Elemental Security to make it work on HP-UX 11 on
822 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
823
Georg Brandl4550b8d2005-08-26 06:43:52 +0000824- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000825 (fixes bug #1119418).
826
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000827- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
828
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000829- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
830 exceptions that cause a function to exit.
831
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000832- The implementation of set() and frozenset() was revised to use its
833 own internal data structure. Memory consumption is reduced by 1/3
834 and there are modest speed-ups as well. The API is unchanged.
835
Tim Petersde7990b2005-07-17 23:45:23 +0000836- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
837
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000838- SF bug #1229429: PyObject_CallMethod failed to decrement some
839 reference counts in some error exit cases.
840
Tim Petersecc6e6a2005-07-10 22:30:55 +0000841- SF bug #1185883: Python's small-object memory allocator took over
842 a block managed by the platform C library whenever a realloc specified
843 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000844 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000845 portable way to copy data from the C-managed block into Python's
846 small-object space without risking a memory fault. Python's small-object
847 realloc now leaves such blocks under the control of the platform C
848 realloc.
849
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000850- SF bug #1232517: An overflow error was not detected properly when
851 attempting to convert a large float to an int in os.utime().
852
Raymond Hettinger3296e692005-06-29 23:29:56 +0000853- SF bug #1224347: hex longs now print with lowercase letters just
854 like their int counterparts.
855
Michael W. Hudson188d4362005-06-20 16:52:57 +0000856- SF bug #1163563: the original fix for bug #1010677 ("thread Module
857 Breaks PyGILState_Ensure()") broke badly in the case of multiple
858 interpreter states; back out that fix and do a better job (see
859 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
860 for a longer write-up of the problem).
861
Michael W. Hudsondf888462005-06-03 14:41:55 +0000862- SF patch #1180995: marshal now uses a binary format by default when
863 serializing floats.
864
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000865- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
866 the routines that promise to produce IEEE 754 binary representations
867 of floats now simply copy bytes around.
868
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000869- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
870 278.
871
Brett Cannonc3647ac2005-04-26 03:45:26 +0000872- patch #1109424: int, long, float, complex, and unicode now check for the
873 proper magic slot for type conversions when subclassed. Previously the
874 magic slot was ignored during conversion. Semantics now match the way
875 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000876 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000877 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000878 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000879
Barry Warsawc8d907c2005-04-19 23:43:40 +0000880- Descriptors defined in C with a PyGetSetDef structure, where the setter is
881 NULL, now raise an AttributeError when attempting to set or delete the
882 attribute. Previously a TypeError was raised, but this was inconsistent
883 with the equivalent pure-Python implementation.
884
Michael W. Hudson774479c2005-04-18 08:46:17 +0000885- It is now safe to call PyGILState_Release() before
886 PyEval_InitThreads() (note that if there is reason to believe there
887 are multiple threads around you still must call PyEval_InitThreads()
888 before using the Python API; this fix is for extension modules that
889 have no way of knowing if Python is multi-threaded yet).
890
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000891- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
892 disabled caused a crash.
893
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000894- Bug #1165306: instancemethod_new allowed the creation of a method
895 with im_class == im_self == NULL, which caused a crash when called.
896
Tim Petersecc6e6a2005-07-10 22:30:55 +0000897- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000898 fixes the crash seen in bug #1165761
899
Raymond Hettinger96229b12005-03-11 06:49:40 +0000900- Added two new builtins, any() and all().

Brett Cannonf4189912005-04-09 02:30:16 +0000903 (e.g., ``class C(): pass`` is no longer a syntax error).
904 Patch #1176012 added support to the 'parser' module and 'compiler' package
905 (thanks to logistix for that added support).

Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000921 an ferror() call.
922
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000923- min() and max() now support key= arguments with the same meaning as in

Jeremy Hyltonab630502005-02-04 18:44:06 +0000934- The parser did not complain about future statements in illegal

941
Tim Petersf4e69282006-02-27 17:15:31 +0000942- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
943 current thread state when the auto-GIL-state machinery knows about
944 it (since the thread state is being deleted, continuing to remember it
945 can't help, but can hurt if another thread happens to get created with
946 the same thread id).

1136-------
1137
Nick Coghlan43832302006-04-23 17:04:07 +00001138- PEP 338: new module runpy defines a run_module function to support
1139 executing modules which provide access to source code or a code object
1140 via the PEP 302 import mechanisms.

1151
Anthony Baxterc51ee692006-04-01 00:57:31 +00001152- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001153 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001154 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001155 module will not be built.
1156
Tim Petersc17976e2006-04-01 00:26:53 +00001157- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1158 aren't officially supported here, and trying to use them will probably
1159 raise an exception some day. But dicts have been allowed, and "mostly
1160 worked", so support for them won't go away without warning.
1161
Georg Brandl338ef7d2006-03-31 18:42:16 +00001162- Bug #1445068: getpass.getpass() can now be given an explicit stream

1180
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001181- email 4.0 package now integrated. This is largely the same as the email 3.0
1182 package that was included in Python 2.3, except that PEP 8 module names are
1183 now used (e.g. mail.message instead of email.Message). The MIME classes
1184 have been moved to a subpackage (e.g. email.mime.text instead of
1185 email.MIMEText). The old names are still supported for now. Several
1186 deprecated Message methods have been removed and lots of bugs have been
1187 fixed. More details can be found in the email package documentation.
1188

1190 (a subclass of tuple) that provides incremental decoders and encoders
1191 (a way to use stateful codecs without the stream API). Python functions
1192 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1193 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1194 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001195
Walter Dörwald067db482006-03-15 22:17:27 +00001196- Patch #1359365: Calling next() on a closed StringIO.String object raises
1197 a ValueError instead of a StopIteration now (like file and cString.String do).
1198 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1199 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00001273 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1274 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1275 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1276 Ronald L. Rivest offered this advice for Python:
1277
1278 "The consensus of researchers in this area (at least as
1279 expressed at the NIST Hash Function Workshop 10/31/05),
1280 is that SHA-256 is a good choice for the time being, but
1281 that research should continue, and other alternatives may
1282 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001283
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001284- Added a subset of Fredrik Lundh's ElementTree package. Available

Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001431- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1432
Martin v. Löwisdf241532005-03-03 08:17:42 +00001433- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1434

1440
Raymond Hettingerbab41432005-02-05 01:31:19 +00001441- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1442
Guido van Rossumd0641422005-02-03 15:01:24 +00001443- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1444 disables recursive traversal through instance attributes, which can
1445 be exploited in various ways.
1446
Tim Peterse3547fd2005-12-16 23:13:57 +00001447- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001448 flags on the HTTP listening socket.
1449
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001450- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1451 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1452
Tim Peterse3547fd2005-12-16 23:13:57 +00001453- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001454 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

1459
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001460- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1461
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001462- Enhancements to the csv module:
1463
1464 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001465 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001466 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001467 + Dialect parameter parsing has been re-implemented to improve error
1468 reporting.
1469 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1470 dictates.
1471 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001472 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001473 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001474 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1475 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001476 + reader now allows \r characters to be quoted (previously it only allowed
1477 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001478 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001479 + Dialect classes passed to the module are no longer instantiated by
1480 the module before being parsed (the former validation scheme required
1481 this, but the mechanism was unreliable).
1482 + The dialect registry now contains instances of the internal
1483 C-coded dialect type, rather than references to python objects.
1484 + the internal c-coded dialect type is now immutable.
1485 + register_dialect now accepts the same keyword dialect specifications
1486 as the reader and writer, allowing the user to register dialects
1487 without first creating a dialect class.
1488 + a configurable limit to the size of parsed fields has been added -
1489 previously, an unmatched quote character could result in the entire
1490 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001491 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001492 the parser field size limit (returning the former limit). The initial
1493 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001494 + A line_num attribute has been added to the reader object, which tracks
1495 the number of lines read from the source iterator. This is not
1496 the same as the number of records returned, as records can span
1497 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001498 + reader and writer objects were not being registered with the cyclic-GC.
1499 This has been fixed.
1500
Brett Cannone6539c42005-01-08 02:43:53 +00001501- _DummyThread objects in the threading module now delete self.__block that is
1502 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1503 lock primitives tend to be limited in number and thus should not be wasted on
1504 a _DummyThread object. Fixes bug #1089632.
1505
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001506- The imghdr module now detects Exif files.
1507
Raymond Hettinger6065d322004-12-20 23:51:53 +00001508- StringIO.truncate() now correctly adjusts the size attribute.
1509 (Bug #951915).
1510
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001511- locale.py now uses an updated locale alias table (built using
1512 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1513 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001514 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001515
Raymond Hettinger3557f422004-12-07 12:02:02 +00001516- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1517
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001518- the pickle module no longer accepts the deprecated None option in the
1519 args tuple returned by __reduce__().
1520
Brett Cannon84667c02004-12-07 03:25:18 +00001521- optparse now optionally imports gettext. This allows its use in setup.py.
1522
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001523- the pickle module no longer uses the deprecated bin parameter.
1524
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001525- the shelve module no longer uses the deprecated binary parameter.
1526
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001527- the pstats module no longer uses the deprecated ignore() method.
1528
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001529- the filecmp module no longer uses the deprecated use_statcache argument.
1530
Raymond Hettinger664347b2004-12-04 21:21:53 +00001531- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1532 extended or overridden by subclasses. Formerly, the subclassed method would
1533 be ignored by the rest of the module. (Bug #1078905).
1534
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001535- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001536 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001537
Walter Dörwald36733692004-12-22 12:50:50 +00001538- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1539 once when a size argument is given. This prevents a buffer overflow in the
1540 tokenizer with very long source lines.
1541
Barry Warsaw538561e2006-01-01 21:48:54 +00001542- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1543 immediately after creating the object, without any intervening
1544 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001545
Skip Montanaro05885812005-01-16 20:48:27 +00001546- The reconvert.quote function can now emit triple-quoted strings. The
1547 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001548
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001549- ``UserString.MutableString`` now supports negative indices in
1550 ``__setitem__`` and ``__delitem__``
1551
Greg Ward40407942005-03-05 02:53:17 +00001552- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1553 correctly.
1554
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001555- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1556 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1557 character even if the user has passed a size parameter to get a proper
1558 line ending. Remove the special handling of a "\r\n" that has been split
1559 between two lines.
1560
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001561- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1562 about illegal code points. The codec now supports PEP 293 style error
1563 handlers.
1564
Walter Dörwald78a78b02005-09-01 12:04:29 +00001565- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001566 from the input stream, so that the output is a byte string in the correct
1567 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001568
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001569- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1570 considering it exactly like a '*'.
1571
Walter Dörwald007f8df2005-10-09 19:42:27 +00001572- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1573 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001574
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001575- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1576
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001577- Patch #1413711: Certain patterns of differences were making difflib
1578 touch the recursion limit.
1579
Walter Dörwald58917a62006-03-31 15:26:22 +00001580- Bug #947906: An object oriented interface has been added to the calendar
1581 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001582 called as a script (e.g. via ``python -mcalendar``). Localized month and
1583 weekday names can be ouput (even if an exotic encoding is used) using
1584 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001585
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001586Build
1587-----
1588
Neal Norwitz602d3392006-03-31 08:21:40 +00001589- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1590 by using -mieee gcc option.
1591

1593
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001594- Build support for Win64-AMD64 was added.
1595
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001596- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1597
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001598- Patch #881820: look for openpty and forkpty also in libbsd.
1599
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001600- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1601 The zlib module is now builtin on Windows.
1602
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001603- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1604
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001605- Bug #1189330: configure did not correctly determine the necessary
1606 value of LINKCC if python was built with GCC 4.0.
1607
Trent Mick8321b422005-07-26 02:29:21 +00001608- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1609 vulnerability in zlib 1.2.1 and 1.2.2.
1610
Brett Cannon08cd5982005-04-24 22:26:38 +00001611- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1612 flags that change binary compatibility. Changes were also made to
1613 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001614 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001615
Bob Ippolitoed233462005-03-29 13:47:59 +00001616- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1617 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1618 no longer exists). This configure patch makes things right.
1619
Martin v. Löwise2713be2005-03-08 15:03:08 +00001620- Bug #1158607: Build with --disable-unicode again.
1621
Brett Cannon46d96232005-02-16 00:07:19 +00001622- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1623 defined. Discovered as a result of not being able to build on OS X.
1624
Brett Cannon516592f2004-12-07 00:42:59 +00001625- setup.py now uses the directories specified in LDFLAGS using the -L option
1626 and in CPPFLAGS using the -I option for adding library and include
1627 directories, respectively, for compiling extension modules against. This has
1628 led to the core being compiled using the values in CPPFLAGS. It also removes
1629 the need for the special-casing of both DarwinPorts and Fink for darwin since
1630 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1631 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1632 Fink, ``-I/opt/local/include`` for DarwinPorts).
1633
Brett Cannon43802422005-02-10 20:48:03 +00001634- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1635 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1636 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1637 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001639C API
1640-----
1641
Tim Petersc9d78aa2006-03-26 23:27:58 +00001642- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1643 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1644 is obtained via the ``PyObject_`` family, it must be released via the
1645 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1646 always been officially true, but when Python's small-object allocator was
1647 introduced, an attempt was made to cater to a few extension modules
1648 discovered at the time that obtained memory via ``PyObject_New`` but
1649 released it via ``PyMem_DEL``. It's years later, and if such code still
1650 exists it will fail now (probably with segfaults, but calling wrong
1651 low-level memory management functions can yield many symptoms).
1652
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001653- Added a C API for set and frozenset objects.
1654

1656
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001657- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1658 mapping argument now. This string is used as a mapping table. Byte values
1659 greater than the length of the string and 0xFFFE are treated as undefined
1660 mappings.
