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.
38
Georg Brandlad29e632006-06-21 17:45:17 +000039Library
40-------
41
Martin v. Löwis8d656812006-07-10 07:23:48 +000042- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
43 environment variable to be set in order to the SDK environment
44 for finding the compiler, include files, etc.
45
Martin v. Löwis388a8c22006-07-06 19:28:03 +000046- Bug #1515998: Properly generate logical ids for files in bdist_msi.

49
Thomas Heller5becdbe2006-07-06 08:48:35 +000050- Patch #1517790: It is now possible to use custom objects in the ctypes
51 foreign function argtypes sequence as long as they provide a from_param
52 method, no longer is it required that the object is a ctypes type.
53
Thomas Woutersadd19112006-07-05 11:03:49 +000054- string.Template() now correctly handles tuple-values. Previously,
55 multi-value tuples would raise an exception and single-value tuples would
56 be treated as the value they contain, instead.
57
Martin v. Löwisede77f52006-07-03 13:01:35 +000058- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

62 spec file generated by bdist_rpm.
63
Martin v. Löwis2b88f632006-07-03 10:19:49 +000064- Bug #1514693: Update turtle's heading when switching between
65 degrees and radians.
66
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000067- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +000068 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000069
Martin v. Löwisbd39c032006-07-03 09:44:00 +000070- Bug #1514703: Only setup canvas window in turtle when the canvas
71 is created.
72
Martin v. Löwis7596e832006-07-01 15:33:37 +000073- Bug #1513223: .close() of a _socketobj now releases the underlying
74 socket again, which then gets closed as it becomes unreferenced.
75
Thomas Hellerbde08132006-06-29 18:34:15 +000076- The '_ctypes' extension module now works when Python is configured
77 with the --without-threads option.
78
Fred Drake10497c82006-06-29 02:57:48 +000079- Bug #1504333: Make sgmllib support angle brackets in quoted
80 attribute values.
81
82- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
83 sgmllib ('[' and ']' were not accepted).
84
Georg Brandl1be63af2006-06-28 20:23:25 +000085- Fix a bug in the turtle module's end_fill function.
86
Brett Cannon53ab5b72006-06-22 16:49:14 +000087- Bug #1510580: The 'warnings' module improperly required that a Warning
88 category be either a types.ClassType and a subclass of Warning. The proper
89 check is just that it is a subclass with Warning as the documentation states.
90
Georg Brandlad29e632006-06-21 17:45:17 +000091- The compiler module now correctly compiles the new try-except-finally
92 statement (bug #1509132).
93
Neal Norwitz60373cd2006-06-22 06:30:50 +000094- The wsgiref package is now installed properly on Unix.
95
Vinay Sajip28e57612006-07-01 10:45:20 +000096- A bug was fixed in logging.config.fileConfig() which caused a crash on
97 shutdown when fileConfig() was called multiple times.
98
Gerhard Häring762fbd32006-07-02 17:48:30 +000099- The sqlite3 module did cut off data from the SQLite database at the first
100 null character before sending it to a custom converter. This has been fixed
101 now.
102
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000103Extension Modules
104-----------------
105
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000106- Bug #1513646: os.access on Windows now correctly determines write
107 access, again.
108
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000109- Bug #1512695: cPickle.loads could crash if it was interrupted with
110 a KeyboardInterrupt.
111
Neal Norwitza12aa882006-07-06 06:45:08 +0000112- Bug #1296433: parsing XML with a non-default encoding and
113 a CharacterDataHandler could crash the interpreter in pyexpat.
114
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000115- Patch #1516912: improve Modules support for OpenVMS.

118-----
119
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000120- 'configure' now detects the zlib library the same way as distutils.
121 Previously, the slight difference could cause compilation errors of the
122 'zlib' module on systems with more than one version of zlib.
123
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000124- The MSI compileall step was fixed to also support a TARGETDIR
125 with spaces in it.
126
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000127- Bug #1517388: sqlite3.dll is now installed on Windows independent
128 of Tcl/Tk.
129
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000130- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000131 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000132
Neal Norwitzb15ac312006-06-29 04:10:08 +0000133Tests
134-----
135
136- Call os.waitpid() at the end of tests that spawn child processes in order
137 to minimize resources (zombies).
138
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000139Documentation
140-------------
141
Nick Coghlan2d792252006-07-06 13:47:18 +0000142- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
143 documentation for the warnings module.
144
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000145- Patch #1509163: MS Toolkit Compiler no longer available.
146

Nick Coghlanc649ec52006-05-29 12:43:05 +0000149What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000150================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000151
Anthony Baxterd1136802006-06-19 12:04:15 +0000152*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000153
154Core and builtins
155-----------------
156
Georg Brandla56b9152006-06-19 06:35:54 +0000157- Patch #1507676: Error messages returned by invalid abstract object operations
158 (such as iterating over an integer) have been improved and now include the
159 type of the offending object to help with debugging.
160
Brett Cannonea3912b2006-06-13 21:46:41 +0000161- Bug #992017: A classic class that defined a __coerce__() method that returned
162 its arguments swapped would infinitely recurse and segfault the interpreter.
163
Neal Norwitz909eb122006-06-12 02:13:21 +0000164- Fix the socket tests so they can be run concurrently.
165
Neal Norwitzb9845e72006-06-12 02:11:18 +0000166- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000167 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000168
Brett Cannon22565aa2006-06-09 22:31:23 +0000169- Bug #532646: object.__call__() will continue looking for the __call__
170 attribute on objects until one without one is found. This leads to recursion
171 when you take a class and set its __call__ attribute to an instance of the
172 class. Originally fixed for classic classes, but this fix is for new-style.
173 Removes the infinite_rec_3 crasher.
174
Georg Brandl24250812006-06-09 18:45:48 +0000175- The string and unicode methods startswith() and endswith() now accept
176 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
177
Brett Cannonde3b0522006-06-08 17:00:45 +0000178- Buffer objects, at the C level, never used the char buffer
179 implementation even when the char buffer for the wrapped object was
180 explicitly requested (originally returned the read or write buffer).
181 Now a TypeError is raised if the char buffer is not present but is
182 requested.
183
Georg Brandlddbaa662006-06-04 21:56:52 +0000184- Patch #1346214: Statements like "if 0: suite" are now again optimized
185 away like they were in Python 2.4.
186
Georg Brandlb7c8f542006-05-27 12:30:25 +0000187- Builtin exceptions are now full-blown new-style classes instead of
188 instances pretending to be classes, which speeds up exception handling
189 by about 80% in comparison to 2.5a2.
190
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000191- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
192 Unicode 4.1.
193
Georg Brandlf4ef1162006-05-26 18:03:31 +0000194- Patch #921466: sys.path_importer_cache is now used to cache valid and
195 invalid file paths for the built-in import machinery which leads to
196 fewer open calls on startup.
197
Tim Peters696cf432006-05-24 21:10:40 +0000198- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
199 of-2 bases. The largest speedup is for inputs with about 1000 decimal
200 digits. Conversion from non-power-of-2 bases remains quadratic-time in
201 the number of input digits (it was and remains linear-time for bases
202 2, 4, 8, 16 and 32).
203
Tim Petersb713ec22006-05-23 18:45:30 +0000204- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
205 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
206 an integer close to ``sys.maxint``. This was repaired by patch
207 #1335972, which also gives a nice speedup.
208
Richard Jonescebbefc2006-05-23 18:28:17 +0000209- Patch #1337051: reduced size of frame objects.
210
211- PyErr_NewException now accepts a tuple of base classes as its
212 "base" parameter.
213
Richard Jones7c88dcc2006-05-23 10:37:38 +0000214- Patch #876206: function call speedup by retaining allocated frame
215 objects.
216
Georg Brandl7b90e162006-05-18 07:01:27 +0000217- Bug #1462152: file() now checks more thoroughly for invalid mode
218 strings and removes a possible "U" before passing the mode to the
219 C library function.
220
Neal Norwitz1004a532006-05-15 07:17:23 +0000221- Patch #1488312, Fix memory alignment problem on SPARC in unicode
222
Neal Norwitz373f0a72006-05-15 07:04:36 +0000223- Bug #1487966: Fix SystemError with conditional expression in assignment
224
Martin v. Löwis879768d2006-05-11 13:28:43 +0000225- WindowsError now has two error code attributes: errno, which carries
226 the error values from errno.h, and winerror, which carries the error
227 values from winerror.h. Previous versions put the winerror.h values
228 (from GetLastError()) into the errno attribute.
229
Martin v. Löwis77736712006-05-04 05:51:03 +0000230- Patch #1475845: Raise IndentationError for unexpected indent.
231
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000232- Patch #1479181: split open() and file() from being aliases for each other.
233
Tim Peters44bd9862006-06-01 13:49:23 +0000234- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
235 methods were always silently ignored by dictionaries when comparing keys.
236 They are now passed through (except when using the C API function
237 ``PyDict_GetItem()``, whose semantics did not change).
238
239- Bug #1456209: In some obscure cases it was possible for a class with a
240 custom ``__eq__()`` method to confuse dict internals when class instances
241 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
242 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000244Extension Modules
245-----------------
246
Trent Mick960a3f82006-06-28 20:30:41 +0000247- Bug #1295808: expat symbols should be namespaced in pyexpat
248
249- Patch #1462338: Upgrade pyexpat to expat 2.0.0
250
Brett Cannon6ee7d012006-06-08 16:23:04 +0000251- Change binascii.hexlify to accept a read-only buffer instead of only a char
252 buffer and actually follow its documentation.
253
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000254- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
255
Nick Coghlanc649ec52006-05-29 12:43:05 +0000256- Patch #1478788 (modified version): The functional extension module has
257 been renamed to _functools and a functools Python wrapper module added.
258 This provides a home for additional function related utilities that are
259 not specifically about functional programming. See PEP 309.
260
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000261- Patch #1493701: performance enhancements for struct module.
262
Georg Brandl378d5922006-05-17 14:26:50 +0000263- Patch #1490224: time.altzone is now set correctly on Cygwin.
264
Georg Brandl8d3342b2006-05-16 07:38:27 +0000265- Patch #1435422: zlib's compress and decompress objects now have a
266 copy() method.
267
Andrew MacIntyre92913322006-06-13 15:04:24 +0000268- Patch #1454481: thread stack size is now tunable at runtime for thread
269 enabled builds on Windows and systems with Posix threads support.
270
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000271- On Win32, os.listdir now supports arbitrarily-long Unicode path names
272 (up to the system limit of 32K characters).
273
274- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
275 As a result, these functions now raise WindowsError instead of OSError.
276
Tim Peters7a822da2006-05-25 21:50:17 +0000277- ``time.clock()`` on Win64 should use the high-performance Windows
278 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
279 Windows platforms).
280
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000281- Calling Tk_Init twice is refused if the first call failed as that
282 may deadlock.
283
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000284- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
285 accept it without potentially using an uninitialized pointer.
286
287- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
288 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
289 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000290
Gregory P. Smith372b5832006-06-05 18:48:21 +0000291- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000292 [pybsddb project SF patch number 1466734]
293
Gregory P. Smith372b5832006-06-05 18:48:21 +0000294- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
295 parameter is supplied. [SF pybsddb bug #1477863]
296
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000297- bsddb: the __len__ method of a DB object has been fixed to return correct
298 results. It could previously incorrectly return 0 in some cases.
299 Fixes SF bug 1493322 (pybsddb bug 1184012).
300
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000301- bsddb: the bsddb.dbtables Modify method now raises the proper error and
302 aborts the db transaction safely when a modifier callback fails.
303 Fixes SF python patch/bug #1408584.
304
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000305- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000306 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000307 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry

332 mime.types file for determining MIME types.
333
Georg Brandl2605ca82006-06-14 06:08:31 +0000334- Bug #1339007: Shelf objects now don't raise an exception in their

336
Martin v. Löwisd8251432006-06-14 05:21:04 +0000337- Patch #1455898: The MBCS codec now supports the incremental mode for
338 double-byte encodings.
339
Tim Peters43898b42006-06-14 04:09:25 +0000340- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
341 guarantee that adjacent triples in the return list always describe
342 non-adjacent blocks. Previously, a pair of matching blocks could end
343 up being described by multiple adjacent triples that formed a partition
344 of the matching pair.
345
Greg Ward0e0c9f42006-06-11 16:24:11 +0000346- Bug #1498146: fix optparse to handle Unicode strings in option help,
347 description, and epilog.
348
Greg Wardd1c797e2006-06-11 14:42:41 +0000349- Bug #1366250: minor optparse documentation error.

352 clarify docs.
353
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000354- The wsgiref package has been added to the standard library.
355
Nick Coghlan676725d2006-06-08 13:54:49 +0000356- The functions update_wrapper() and wraps() have been added to the functools
357 module. These make it easier to copy relevant metadata from the original
358 function when writing wrapper functions.
359
Tim Petersd6a9eef2006-06-05 01:48:21 +0000360- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
361 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000362
Martin v. Löwis3f767792006-06-04 19:36:28 +0000363- Patch #1359618: Speed up charmap encoder by using a trie structure
364 for lookup.
365
Tim Petersd609b1a2006-06-02 23:22:51 +0000366- The functions in the ``pprint`` module now sort dictionaries by key
367 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
368 if and only if its display required more than one line, although that
369 wasn't documented. The new behavior increases predictability; e.g.,
370 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
371
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000372- Patch #1497027: try HTTP digest auth before basic auth in urllib2

381
Georg Brandlb89316f2006-05-17 15:51:16 +0000382- Patch #1180296: Two new functions were added to the locale module:
383 format_string() to get the effect of "format % items" but locale-aware,
384 and currency() to format a monetary number with currency sign.
385
Georg Brandle3a25832006-05-17 14:56:04 +0000386- Patch #1486962: Several bugs in the turtle Tk demo module were fixed

390 tarfiles.
391
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000392- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
393 stdout arguments, making it possible to redirect input and output
394 for remote debugging.
395
396- Patch #1484695: Update the tarfile module to version 0.8. This fixes
397 a couple of issues, notably handling of long file names using the
398 GNU LONGNAME extension.
399

401 new flag when ``name`` is already the name of an option flag.
402
403- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
404 package.
405

445*Release date: 27-APR-2006*
446
447Core and builtins
448-----------------
449
Thomas Heller1b046642006-04-18 18:51:06 +0000450- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
451 by converting these apis from macros into exported functions again:
452
453 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
454 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
455 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
456 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
457 PyRun_String Py_CompileString
458
Martin v. Löwis45294a92006-04-18 06:24:08 +0000459- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
460
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000461- All uses of PyStructSequence_InitType have been changed to initialize
462 the type objects only once, even if the interpreter is initialized
463 multiple times.
464
Neal Norwitz61546162006-04-14 05:20:28 +0000465- Bug #1454485, array.array('u') could crash the interpreter. This was
466 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
467 to unicode when it didn't make sense. 'u#' now requires a unicode string.
468
469- Py_UNICODE is unsigned. It was always documented as unsigned, but
470 due to a bug had a signed value in previous versions.
471
Tim Peters3a5e8b12006-04-11 01:44:07 +0000472- Patch #837242: ``id()`` of any Python object always gives a positive
473 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
474 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000475 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000476 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000477
Tim Peters3a5e8b12006-04-11 01:44:07 +0000478 def __hash__(self):
479 return id(self) # WRONG
480
481 because a hash result must be a (short) Python int but it was always
482 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000483 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000484 was always usable as a hash value before this patch. That's no longer
485 necessarily so.
486
487- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000488 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000489 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000490 #1454844)
491
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000492- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
493 involving generators that have paused outside of any ``try`` or ``with``
494 blocks. (In 2.5a1, a paused generator that was part of a reference
495 cycle could not be garbage collected, regardless of whether it was
496 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +0000524- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
525 a doctest to be skipped (the code is not run, and the expected output
526 or exception is ignored).
527
Nick Coghlanda2268f2006-04-24 04:37:15 +0000528- Fixed contextlib.nested to cope with exceptions being raised and
529 caught inside exit handlers.
530
Greg Wardab05edc2006-04-23 03:47:58 +0000531- Updated optparse module to Optik 1.5.1 (allow numeric constants in
532 hex, octal, or binary; add ``append_const`` action; keep going if
533 gettext cannot be imported; added ``OptionParser.destroy()`` method;
534 added ``epilog`` for better help generation).
535
Tim Peters21fbd572006-04-21 21:18:10 +0000536- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
537 called from a thread spawned as a side effect of importing a module.
538
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000539- The pydoc module now supports documenting packages contained in
540 .zip or .egg files.
541
542- The pkgutil module now has several new utility functions, such
543 as ``walk_packages()`` to support working with packages that are either
544 in the filesystem or zip files.
545
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000546- The mailbox module can now modify and delete messages from
547 mailboxes, in addition to simply reading them. Thanks to Gregory
548 K. Johnson for writing the code, and to the 2005 Google Summer of
549 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000550
Tim Petersc7605f22006-04-17 21:12:33 +0000551- The ``__del__`` method of class ``local`` in module ``_threading_local``
552 returned before accomplishing any of its intended cleanup.
553
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000554- Patch #790710: Add breakpoint command lists in pdb.

Anthony Baxtere29002c2006-04-12 12:07:31 +0000560- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
561 Windows. Bug #1469163.
562
Phillip J. Eby47032112006-04-11 01:07:43 +0000563- The warnings, linecache, inspect, traceback, site, and doctest modules
564 were updated to work correctly with modules imported from zipfiles or

588 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000589 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000590 CXX from --with-cxx-main, see description in README.
591

Nick Coghlan27ec1a72006-04-24 04:32:47 +0000606- test_cmd_line now checks operation of the -m and -c command switches
607
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000608- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
609 it separately and by hand. It also wasn't cleaning up its changes to
610 the current Decimal context.
611
Thomas Woutersabd08882006-04-26 15:53:30 +0000612- regrtest.py now has a -M option to run tests that test the new limits of
613 containers, on 64-bit architectures. Running these tests is only sensible
614 on 64-bit machines with more than two gigabytes of memory. The argument
615 passed is the maximum amount of memory for the tests to use.

629 and attempted to bring other PEP 343 related documentation into
630 line with the implementation and/or python-dev discussions.
631
Tim Peters8dc73d22006-04-24 02:03:16 +0000632- Bug #1337990: clarified that ``doctest`` does not support examples
633 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000636What's New in Python 2.5 alpha 1?
637=================================
638
Anthony Baxterebed3f62006-04-03 15:03:44 +0000639*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000640
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000641Core and builtins
642-----------------
643
Nick Coghlan43832302006-04-23 17:04:07 +0000644- PEP 338: -m command line switch now delegates to runpy.run_module
645 allowing it to support modules in packages and zipfiles
646
Martin v. Löwisc661b882006-04-20 04:54:23 +0000647- On Windows, .DLL is not an accepted file name extension for
648 extension modules anymore; extensions are only found if they
649 end in .PYD.
650
Martin v. Löwisea62d252006-04-03 10:56:49 +0000651- Bug #1421664: sys.stderr.encoding is now set to the same value as
652 sys.stdout.encoding.
653
Neal Norwitz92e212f2006-04-03 04:48:37 +0000654- __import__ accepts keyword arguments.
655
Georg Brandlccadf842006-03-31 18:54:53 +0000656- Patch #1460496: round() now accepts keyword arguments.
657
Anthony Baxter262c00a2006-03-30 10:53:17 +0000658- Fixed bug #1459029 - unicode reprs were double-escaped.
659
Hye-Shik Changd478f342006-03-23 12:32:36 +0000660- Patch #1396919: The system scope threads are reenabled on FreeBSD
661 5.4 and later versions.
662
Neal Norwitze98ccf62006-03-23 05:39:47 +0000663- Bug #1115379: Compiling a Unicode string with an encoding declaration
664 now gives a SyntaxError.
665
Georg Brandlabd1ff82006-03-18 07:59:59 +0000666- Previously, Python code had no easy way to access the contents of a
667 cell object. Now, a ``cell_contents`` attribute has been added
668 (closes patch #1170323).
669
Tim Peterscf79aac2006-03-16 01:14:46 +0000670- Patch #1123430: Python's small-object allocator now returns an arena to
671 the system ``free()`` when all memory within an arena becomes unused
672 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
673 freed. Some applications will see a drop in virtual memory size now,
674 especially long-running applications that, from time to time, temporarily
675 use a large number of small objects. Note that when Python returns an
676 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000677 platform C library will in turn return that memory to the operating system.
678 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000679 appears to be effective at least on Microsoft C and gcc-based systems.
680 Thanks to Evan Jones for hard work and patience.
681
Georg Brandl533ff6f2006-03-08 18:09:27 +0000682- Patch #1434038: property() now uses the getter's docstring if there is
683 no "doc" argument given. This makes it possible to legitimately use
684 property() as a decorator to produce a read-only property.
685
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000686- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
687 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
688 of requiring an int or long in slicing and a few other contexts, enabling
689 other objects (e.g. Numeric Python's integers) to be used as slice indices.
690
Neal Norwitz995acdf2006-03-07 05:01:00 +0000691- Fixed various bugs reported by Coverity's Prevent tool.
692
Brett Cannonbf364092006-03-01 04:25:17 +0000693- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
694 new exception base class, BaseException, which has a new message attribute.
695 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
696 Raising a string exception now raises a DeprecationWarning.
697
Thomas Woutersfb609f42006-02-28 16:37:25 +0000698- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
699 explicitly relative, using 'from .module import name' to mean 'from the same
700 package as this module is in. Imports without dots still default to the
701 old relative-then-absolute, unless 'from __future__ import
702 absolute_import' is used.
703
Brett Cannona7446e32006-02-27 23:39:10 +0000704- Properly check if 'warnings' raises an exception (usually when a filter set
705 to "error" is triggered) when raising a warning for raising string
706 exceptions.
707
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000708- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000709 The name was removed from Include/code.h.
710
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000711- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000712
Guido van Rossum1968ad32006-02-25 22:38:04 +0000713- Patch 1433928:
714 - The copy module now "copies" function objects (as atomic objects).
715 - dict.__getitem__ now looks for a __missing__ hook before raising
716 KeyError.
717
Tim Peters84ef21c2006-02-28 20:39:06 +0000718- PEP 343: with statement implemented. Needs ``from __future__ import
719 with_statement``. Use of 'with' as a variable will generate a warning.
720 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000721 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000722 The following objects have __context__ methods:
723 - The built-in file type.
724 - The thread.LockType type.
725 - The following types defined by the threading module:
726 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
727 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000728
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000729- Fix the encodings package codec search function to only search
730 inside its own package. Fixes problem reported in patch #1433198.
731
732 Note: Codec packages should implement and register their own
733 codec search function. PEP 100 has the details.
734
Tim Peters9ea89d22006-06-04 03:26:02 +0000735- PEP 353: Using ``Py_ssize_t`` as the index type.
736
737- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
738 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
739 now allow Python to make use of memory blocks exceeding 2**32 bytes for
740 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
741 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000742
Neal Norwitzfc76d632006-01-10 06:03:13 +0000743- Patch #1400181, fix unicode string formatting to not use the locale.
744 This is how string objects work. u'%f' could use , instead of .
745 for the decimal point. Now both strings and unicode always use periods.
746
Neal Norwitz671b9e32006-01-09 07:07:12 +0000747- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
748 configure would break checking curses.h.
749
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000750- Bug #959576: The pwd module is now builtin. This allows Python to be
751 built on UNIX platforms without $HOME set.
752
Neal Norwitzc10978f2005-12-19 06:07:16 +0000753- Bug #1072182, fix some potential problems if characters are signed.
754
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000755- Bug #889500, fix line number on SyntaxWarning for global declarations.
756
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000757- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
758
Neal Norwitze7214a12005-12-18 05:03:17 +0000759- Support for converting hex strings to floats no longer works.
760 This was not portable. float('0x3') now raises a ValueError.
761
Barry Warsaw2a38a862005-12-18 01:27:35 +0000762- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000763 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000764 is now displayed in interactive prompt banner.
765
Georg Brandlfa166682005-12-17 21:45:17 +0000766- Implementation of PEP 341 - Unification of try/except and try/finally.
767 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000768 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000769
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000770- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
771 now encodes backslash correctly.
772
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000773- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
774
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000775- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000776 and long longs.
777
Neal Norwitz67715f02005-11-09 06:59:35 +0000778- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000779 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000780 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000781
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000782- Replaced most Unicode charmap codecs with new ones using the
783 new Unicode translate string feature in the builtin charmap
784 codec; the codecs were created from the mapping tables available
785 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
786 encodings now include a mapping for the Apple logo)
787
Tim Peterse3547fd2005-12-16 23:13:57 +0000788- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000789
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000790- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000791
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000792- A new AST parser implementation was completed. The abstract
793 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000794 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000795
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000796- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000797 The following code now raises a SyntaxError: foo(a = i for i in range(10))
798
Neal Norwitz708e51a2005-10-03 04:48:15 +0000799- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
800
Neal Norwitz11bd1192005-10-03 00:54:56 +0000801- SF Bug #887946: fix segfault when redirecting stdin from a directory.
802 Provide a warning when a directory is passed on the command line.
803
Neal Norwitz40d37812005-10-02 01:48:49 +0000804- Fix segfault with invalid coding.
805
806- SF bug #772896: unknown encoding results in MemoryError.
807
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000808- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000809 supported a __len__() method which evaluated to False when the iterator
810 was empty.
811
Guido van Rossum630db602005-09-20 18:49:54 +0000812- On 64-bit platforms, when __len__() returns a value that cannot be
813 represented as a C int, raise OverflowError.
814
Skip Montanarof8948ca2005-09-19 03:54:46 +0000815- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000816 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000817
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000818- SF bug #893549: parsing keyword arguments was broken with a few format
819 codes.
820
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000821- Changes donated by Elemental Security to make it work on AIX 5.3
822 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
823 bug #105470: test_pwd fails on 64bit system (Opteron).
824
Guido van Rossum539c6622005-09-14 17:49:54 +0000825- Changes donated by Elemental Security to make it work on HP-UX 11 on
826 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
827
Georg Brandl4550b8d2005-08-26 06:43:52 +0000828- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000829 (fixes bug #1119418).
830
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000831- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
832
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000833- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
834 exceptions that cause a function to exit.
835
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000836- The implementation of set() and frozenset() was revised to use its
837 own internal data structure. Memory consumption is reduced by 1/3
838 and there are modest speed-ups as well. The API is unchanged.
839
Tim Petersde7990b2005-07-17 23:45:23 +0000840- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
841
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000842- SF bug #1229429: PyObject_CallMethod failed to decrement some
843 reference counts in some error exit cases.
844
Tim Petersecc6e6a2005-07-10 22:30:55 +0000845- SF bug #1185883: Python's small-object memory allocator took over
846 a block managed by the platform C library whenever a realloc specified
847 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000848 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000849 portable way to copy data from the C-managed block into Python's
850 small-object space without risking a memory fault. Python's small-object
851 realloc now leaves such blocks under the control of the platform C
852 realloc.
853
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000854- SF bug #1232517: An overflow error was not detected properly when
855 attempting to convert a large float to an int in os.utime().
856
Raymond Hettinger3296e692005-06-29 23:29:56 +0000857- SF bug #1224347: hex longs now print with lowercase letters just
858 like their int counterparts.
859
Michael W. Hudson188d4362005-06-20 16:52:57 +0000860- SF bug #1163563: the original fix for bug #1010677 ("thread Module
861 Breaks PyGILState_Ensure()") broke badly in the case of multiple
862 interpreter states; back out that fix and do a better job (see
863 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
864 for a longer write-up of the problem).
865
Michael W. Hudsondf888462005-06-03 14:41:55 +0000866- SF patch #1180995: marshal now uses a binary format by default when
867 serializing floats.
868
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000869- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
870 the routines that promise to produce IEEE 754 binary representations
871 of floats now simply copy bytes around.
872
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000873- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
874 278.
875
Brett Cannonc3647ac2005-04-26 03:45:26 +0000876- patch #1109424: int, long, float, complex, and unicode now check for the
877 proper magic slot for type conversions when subclassed. Previously the
878 magic slot was ignored during conversion. Semantics now match the way
879 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000880 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000881 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000882 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000883
Barry Warsawc8d907c2005-04-19 23:43:40 +0000884- Descriptors defined in C with a PyGetSetDef structure, where the setter is
885 NULL, now raise an AttributeError when attempting to set or delete the
886 attribute. Previously a TypeError was raised, but this was inconsistent
887 with the equivalent pure-Python implementation.
888
Michael W. Hudson774479c2005-04-18 08:46:17 +0000889- It is now safe to call PyGILState_Release() before
890 PyEval_InitThreads() (note that if there is reason to believe there
891 are multiple threads around you still must call PyEval_InitThreads()
892 before using the Python API; this fix is for extension modules that
893 have no way of knowing if Python is multi-threaded yet).
894
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000895- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
896 disabled caused a crash.
897
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000898- Bug #1165306: instancemethod_new allowed the creation of a method
899 with im_class == im_self == NULL, which caused a crash when called.
900
Tim Petersecc6e6a2005-07-10 22:30:55 +0000901- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000902 fixes the crash seen in bug #1165761
903

Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000925 an ferror() call.
926
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000927- min() and max() now support key= arguments with the same meaning as in

Jeremy Hyltonab630502005-02-04 18:44:06 +0000938- The parser did not complain about future statements in illegal

941
Neil Schemenauercf52c072005-08-12 17:34:58 +0000942- Change the %s format specifier for str objects so that it returns a
943 unicode instance if the argument is not an instance of basestring and

945
Tim Petersf4e69282006-02-27 17:15:31 +0000946- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
947 current thread state when the auto-GIL-state machinery knows about
948 it (since the thread state is being deleted, continuing to remember it
949 can't help, but can hurt if another thread happens to get created with
950 the same thread id).

1140-------
1141
Nick Coghlan43832302006-04-23 17:04:07 +00001142- PEP 338: new module runpy defines a run_module function to support
1143 executing modules which provide access to source code or a code object
1144 via the PEP 302 import mechanisms.

1155
Anthony Baxterc51ee692006-04-01 00:57:31 +00001156- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001157 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001158 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001159 module will not be built.
1160
Tim Petersc17976e2006-04-01 00:26:53 +00001161- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1162 aren't officially supported here, and trying to use them will probably
1163 raise an exception some day. But dicts have been allowed, and "mostly
1164 worked", so support for them won't go away without warning.
1165
Georg Brandl338ef7d2006-03-31 18:42:16 +00001166- Bug #1445068: getpass.getpass() can now be given an explicit stream

1184
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001185- email 4.0 package now integrated. This is largely the same as the email 3.0
1186 package that was included in Python 2.3, except that PEP 8 module names are
1187 now used (e.g. mail.message instead of email.Message). The MIME classes
1188 have been moved to a subpackage (e.g. email.mime.text instead of
1189 email.MIMEText). The old names are still supported for now. Several
1190 deprecated Message methods have been removed and lots of bugs have been
1191 fixed. More details can be found in the email package documentation.
1192

1194 (a subclass of tuple) that provides incremental decoders and encoders
1195 (a way to use stateful codecs without the stream API). Python functions
1196 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1197 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1198 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001199
Walter Dörwald067db482006-03-15 22:17:27 +00001200- Patch #1359365: Calling next() on a closed StringIO.String object raises
1201 a ValueError instead of a StopIteration now (like file and cString.String do).
1202 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1203 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00001277 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1278 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1279 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1280 Ronald L. Rivest offered this advice for Python:
1281
1282 "The consensus of researchers in this area (at least as
1283 expressed at the NIST Hash Function Workshop 10/31/05),
1284 is that SHA-256 is a good choice for the time being, but
1285 that research should continue, and other alternatives may
1286 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001287
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001288- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettingerbab41432005-02-05 01:31:19 +00001445- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1446
Guido van Rossumd0641422005-02-03 15:01:24 +00001447- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1448 disables recursive traversal through instance attributes, which can
1449 be exploited in various ways.
1450
Tim Peterse3547fd2005-12-16 23:13:57 +00001451- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001452 flags on the HTTP listening socket.
1453
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001454- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1455 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1456
Tim Peterse3547fd2005-12-16 23:13:57 +00001457- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001458 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1459

1463
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001464- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1465
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001466- Enhancements to the csv module:
1467
1468 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001469 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001470 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001471 + Dialect parameter parsing has been re-implemented to improve error
1472 reporting.
1473 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1474 dictates.
1475 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001476 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001477 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001478 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1479 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001480 + reader now allows \r characters to be quoted (previously it only allowed
1481 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001482 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001483 + Dialect classes passed to the module are no longer instantiated by
1484 the module before being parsed (the former validation scheme required
1485 this, but the mechanism was unreliable).
1486 + The dialect registry now contains instances of the internal
1487 C-coded dialect type, rather than references to python objects.
1488 + the internal c-coded dialect type is now immutable.
1489 + register_dialect now accepts the same keyword dialect specifications
1490 as the reader and writer, allowing the user to register dialects
1491 without first creating a dialect class.
1492 + a configurable limit to the size of parsed fields has been added -
1493 previously, an unmatched quote character could result in the entire
1494 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001495 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001496 the parser field size limit (returning the former limit). The initial
1497 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001498 + A line_num attribute has been added to the reader object, which tracks
1499 the number of lines read from the source iterator. This is not
1500 the same as the number of records returned, as records can span
1501 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001502 + reader and writer objects were not being registered with the cyclic-GC.
1503 This has been fixed.
1504
Brett Cannone6539c42005-01-08 02:43:53 +00001505- _DummyThread objects in the threading module now delete self.__block that is
1506 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1507 lock primitives tend to be limited in number and thus should not be wasted on
1508 a _DummyThread object. Fixes bug #1089632.
1509
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001510- The imghdr module now detects Exif files.
1511
Raymond Hettinger6065d322004-12-20 23:51:53 +00001512- StringIO.truncate() now correctly adjusts the size attribute.
1513 (Bug #951915).
1514
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001515- locale.py now uses an updated locale alias table (built using
1516 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1517 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001518 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001519
Raymond Hettinger3557f422004-12-07 12:02:02 +00001520- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1521
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001522- the pickle module no longer accepts the deprecated None option in the
1523 args tuple returned by __reduce__().
1524
Brett Cannon84667c02004-12-07 03:25:18 +00001525- optparse now optionally imports gettext. This allows its use in setup.py.
1526
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001527- the pickle module no longer uses the deprecated bin parameter.
1528
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001529- the shelve module no longer uses the deprecated binary parameter.
1530
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001531- the pstats module no longer uses the deprecated ignore() method.
1532
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001533- the filecmp module no longer uses the deprecated use_statcache argument.
1534
Raymond Hettinger664347b2004-12-04 21:21:53 +00001535- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1536 extended or overridden by subclasses. Formerly, the subclassed method would
1537 be ignored by the rest of the module. (Bug #1078905).
1538
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001539- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001540 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001541
Walter Dörwald36733692004-12-22 12:50:50 +00001542- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1543 once when a size argument is given. This prevents a buffer overflow in the
1544 tokenizer with very long source lines.
1545
Barry Warsaw538561e2006-01-01 21:48:54 +00001546- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1547 immediately after creating the object, without any intervening
1548 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001549
Skip Montanaro05885812005-01-16 20:48:27 +00001550- The reconvert.quote function can now emit triple-quoted strings. The
1551 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001552
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001553- ``UserString.MutableString`` now supports negative indices in
1554 ``__setitem__`` and ``__delitem__``
1555
Greg Ward40407942005-03-05 02:53:17 +00001556- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1557 correctly.
1558
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001559- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1560 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1561 character even if the user has passed a size parameter to get a proper
1562 line ending. Remove the special handling of a "\r\n" that has been split
1563 between two lines.
1564
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001565- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1566 about illegal code points. The codec now supports PEP 293 style error
1567 handlers.
1568
Walter Dörwald78a78b02005-09-01 12:04:29 +00001569- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001570 from the input stream, so that the output is a byte string in the correct
1571 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001572
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001573- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1574 considering it exactly like a '*'.
1575
Walter Dörwald007f8df2005-10-09 19:42:27 +00001576- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1577 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001578
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001579- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1580
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001581- Patch #1413711: Certain patterns of differences were making difflib
1582 touch the recursion limit.
1583
Walter Dörwald58917a62006-03-31 15:26:22 +00001584- Bug #947906: An object oriented interface has been added to the calendar
1585 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001586 called as a script (e.g. via ``python -mcalendar``). Localized month and
1587 weekday names can be ouput (even if an exotic encoding is used) using
1588 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001589
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001590Build

1597
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001598- Build support for Win64-AMD64 was added.
1599
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001600- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1601
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001602- Patch #881820: look for openpty and forkpty also in libbsd.
1603
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001604- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1605 The zlib module is now builtin on Windows.
1606
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001607- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1608
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001609- Bug #1189330: configure did not correctly determine the necessary
1610 value of LINKCC if python was built with GCC 4.0.
1611
Trent Mick8321b422005-07-26 02:29:21 +00001612- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1613 vulnerability in zlib 1.2.1 and 1.2.2.
1614
Brett Cannon08cd5982005-04-24 22:26:38 +00001615- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1616 flags that change binary compatibility. Changes were also made to
1617 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001618 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001619
Bob Ippolitoed233462005-03-29 13:47:59 +00001620- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1621 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1622 no longer exists). This configure patch makes things right.
1623
Martin v. Löwise2713be2005-03-08 15:03:08 +00001624- Bug #1158607: Build with --disable-unicode again.
1625
Brett Cannon46d96232005-02-16 00:07:19 +00001626- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1627 defined. Discovered as a result of not being able to build on OS X.
1628
Brett Cannon516592f2004-12-07 00:42:59 +00001629- setup.py now uses the directories specified in LDFLAGS using the -L option
1630 and in CPPFLAGS using the -I option for adding library and include
1631 directories, respectively, for compiling extension modules against. This has
1632 led to the core being compiled using the values in CPPFLAGS. It also removes
1633 the need for the special-casing of both DarwinPorts and Fink for darwin since
1634 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1635 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1636 Fink, ``-I/opt/local/include`` for DarwinPorts).
1637
Brett Cannon43802422005-02-10 20:48:03 +00001638- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1639 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1640 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1641 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001643C API
1644-----
1645
Tim Petersc9d78aa2006-03-26 23:27:58 +00001646- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1647 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1648 is obtained via the ``PyObject_`` family, it must be released via the
1649 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1650 always been officially true, but when Python's small-object allocator was
1651 introduced, an attempt was made to cater to a few extension modules
1652 discovered at the time that obtained memory via ``PyObject_New`` but
1653 released it via ``PyMem_DEL``. It's years later, and if such code still
1654 exists it will fail now (probably with segfaults, but calling wrong
1655 low-level memory management functions can yield many symptoms).
1656
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001657- Added a C API for set and frozenset objects.
1658
Raymond Hettinger66517482004-12-03 11:45:13 +00001659- Removed PyRange_New().
1660
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001661- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1662 mapping argument now. This string is used as a mapping table. Byte values
1663 greater than the length of the string and 0xFFFE are treated as undefined
1664 mappings.
