13-----------------
14
Neal Norwitze7563102006-07-17 01:00:16 +000015- Fix warnings reported by Klocwork's static analysis tool.
16
Neal Norwitz84be93b2006-07-16 01:50:38 +000017- Bug #1512814, Fix incorrect lineno's when code within a function
18 had more than 255 blank lines.
19
Georg Brandl9dceedb2006-07-12 15:31:17 +000020- Patch #1521179: Python now accepts the standard options ``--help`` and
21 ``--version`` as well as ``/?`` on Windows.
22
Neal Norwitza1f10902006-07-12 07:28:29 +000023- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
24 again. Fixing this problem required changing the .pyc magic number.
25 This means that .pyc files generated before 2.5c1 will be regenerated.

29
Martin v. Löwis426f4a12006-07-18 17:46:31 +000030- Patch #1524429: Use repr() instead of backticks in Tkinter again.
31
Brett Cannoncaebe222006-07-18 04:41:36 +000032- Bug #1520914: Change time.strftime() to accept a zero for any position in its
33 argument tuple. For arguments where zero is illegal, the value is forced to
34 the minimum value that is correct. This is to support an undocumented but
35 common way people used to fill in inconsequential information in the time
36 tuple pre-2.4.
37
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000038- Patch #1220874: Update the binhex module for Mach-O.

Thomas Hellerce049a02006-07-14 17:51:14 +000043- Patch #1521817: Index range checking on ctypes arrays containing
44 exactly one element enabled again. This allows iterating over these
45 arrays, without the need to check the array size before.
46
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000047- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000048 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000049 /dev/null in certain cases; this is now fixed.
50
Thomas Heller47d7a062006-07-12 08:43:47 +000051- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
52 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000053
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000054- Because of a misspelled preprocessor symbol, ctypes was always
55 compiled without thread support; this is now fixed.

62Core and builtins
63-----------------
64
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000065- Bug #1441486: The literal representation of -(sys.maxint - 1)
66 again evaluates to a int object, not a long.
67
Neil Schemenauer0e07b602006-07-09 16:16:34 +000068- Bug #1501934: The scope of global variables that are locally assigned
69 using augmented assignment is now correctly determined.
70
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000071- Bug #927248: Recursive method-wrapper objects can now safely
72 be released.
73
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000074- Bug #1417699: Reject locale-specific decimal point in float()
75 and atof().
76
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000077- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
78 omit a default "error" argument for NULL pointer. This allows
79 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000080
Neal Norwitzfb48afa2006-07-08 05:31:37 +000081- Bug #1519018: 'as' is now validated properly in import statements.
82
Neal Norwitz28746ab2006-07-09 22:14:42 +000083- On 64 bit systems, int literals that use less than 64 bits are
84 now ints rather than longs.
85
Neal Norwitzed657552006-07-10 00:04:44 +000086- Bug #1512814, Fix incorrect lineno's when code at module scope
87 started after line 256.
88
Tim Peters32a83612006-07-10 21:08:24 +000089- New function ``sys._current_frames()`` returns a dict mapping thread
90 id to topmost thread stack frame. This is for expert use, and is
91 especially useful for debugging application deadlocks. The functionality
92 was previously available in Fazal Majid's ``threadframe`` extension
93 module, but it wasn't possible to do this in a wholly threadsafe way from
94 an extension.

Martin v. Löwis06c68b82006-07-10 22:11:28 +000099- Patch #1519566: Update turtle demo, make begin_fill idempotent.
100
Tim Peters32a83612006-07-10 21:08:24 +0000101- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000102 environment variable to be set in order to the SDK environment
103 for finding the compiler, include files, etc.
104
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000105- Bug #1515998: Properly generate logical ids for files in bdist_msi.
106
Nick Coghlan2d792252006-07-06 13:47:18 +0000107- warnings.py now ignores ImportWarning by default
108
Thomas Woutersadd19112006-07-05 11:03:49 +0000109- string.Template() now correctly handles tuple-values. Previously,
110 multi-value tuples would raise an exception and single-value tuples would
111 be treated as the value they contain, instead.
112
Martin v. Löwisede77f52006-07-03 13:01:35 +0000113- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
114 even if some data are received.
115
Martin v. Löwis45482392006-07-03 12:28:58 +0000116- Bug #1267547: Put proper recursive setup.py call into the
117 spec file generated by bdist_rpm.
118
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000119- Bug #1514693: Update turtle's heading when switching between
120 degrees and radians.
121
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000122- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000123 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000124
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000125- Bug #1514703: Only setup canvas window in turtle when the canvas
126 is created.
127
Martin v. Löwis7596e832006-07-01 15:33:37 +0000128- Bug #1513223: .close() of a _socketobj now releases the underlying
129 socket again, which then gets closed as it becomes unreferenced.
130
Fred Drake10497c82006-06-29 02:57:48 +0000131- Bug #1504333: Make sgmllib support angle brackets in quoted
132 attribute values.
133
134- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
135 sgmllib ('[' and ']' were not accepted).
136
Georg Brandl1be63af2006-06-28 20:23:25 +0000137- Fix a bug in the turtle module's end_fill function.
138
Brett Cannon53ab5b72006-06-22 16:49:14 +0000139- Bug #1510580: The 'warnings' module improperly required that a Warning
140 category be either a types.ClassType and a subclass of Warning. The proper
141 check is just that it is a subclass with Warning as the documentation states.
142
Georg Brandlad29e632006-06-21 17:45:17 +0000143- The compiler module now correctly compiles the new try-except-finally
144 statement (bug #1509132).
145
Neal Norwitz60373cd2006-06-22 06:30:50 +0000146- The wsgiref package is now installed properly on Unix.
147
Vinay Sajip28e57612006-07-01 10:45:20 +0000148- A bug was fixed in logging.config.fileConfig() which caused a crash on
149 shutdown when fileConfig() was called multiple times.
150
Gerhard Häring762fbd32006-07-02 17:48:30 +0000151- The sqlite3 module did cut off data from the SQLite database at the first
152 null character before sending it to a custom converter. This has been fixed
153 now.
154
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000155Extension Modules
156-----------------
157
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000158- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
159 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
160 The patch makes sockets use poll() internally where available.
161
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000162- Assigning None to pointer type fields in ctypes structures possible
163 overwrote the wrong fields, this is fixed now.
164
165- Fixed a segfault in _ctypes when ctypes.wintypes were imported
166 on non-Windows platforms.
167
168- Bug #1518190: The ctypes.c_void_p constructor now accepts any
169 integer or long, without range checking.
170
171- Patch #1517790: It is now possible to use custom objects in the ctypes
172 foreign function argtypes sequence as long as they provide a from_param
173 method, no longer is it required that the object is a ctypes type.
174
175- The '_ctypes' extension module now works when Python is configured
176 with the --without-threads option.
177
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000178- Bug #1513646: os.access on Windows now correctly determines write
179 access, again.
180
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000181- Bug #1512695: cPickle.loads could crash if it was interrupted with
182 a KeyboardInterrupt.
183
Neal Norwitza12aa882006-07-06 06:45:08 +0000184- Bug #1296433: parsing XML with a non-default encoding and
185 a CharacterDataHandler could crash the interpreter in pyexpat.
186
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000187- Patch #1516912: improve Modules support for OpenVMS.
188
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000189Build
190-----
191
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000192- Automate Windows build process for the Win64 SSL module.
193
Tim Peters32a83612006-07-10 21:08:24 +0000194- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000195 Previously, the slight difference could cause compilation errors of the
196 'zlib' module on systems with more than one version of zlib.
197
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000198- The MSI compileall step was fixed to also support a TARGETDIR
199 with spaces in it.
200
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000201- Bug #1517388: sqlite3.dll is now installed on Windows independent
202 of Tcl/Tk.
203
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000204- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000205 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000206
Neal Norwitzb15ac312006-06-29 04:10:08 +0000207Tests
208-----
209
210- Call os.waitpid() at the end of tests that spawn child processes in order
211 to minimize resources (zombies).
212
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000213Documentation
214-------------
215
Nick Coghlan2d792252006-07-06 13:47:18 +0000216- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
217 documentation for the warnings module.
218
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000219- Patch #1509163: MS Toolkit Compiler no longer available.
220
Neal Norwitz56640df2006-07-10 02:36:41 +0000221- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000225
Anthony Baxterd1136802006-06-19 12:04:15 +0000226*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000227
228Core and builtins
229-----------------
230
Georg Brandla56b9152006-06-19 06:35:54 +0000231- Patch #1507676: Error messages returned by invalid abstract object operations
232 (such as iterating over an integer) have been improved and now include the
233 type of the offending object to help with debugging.
234
Brett Cannonea3912b2006-06-13 21:46:41 +0000235- Bug #992017: A classic class that defined a __coerce__() method that returned
236 its arguments swapped would infinitely recurse and segfault the interpreter.
237
Neal Norwitz909eb122006-06-12 02:13:21 +0000238- Fix the socket tests so they can be run concurrently.
239
Neal Norwitzb9845e72006-06-12 02:11:18 +0000240- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000241 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000242
Brett Cannon22565aa2006-06-09 22:31:23 +0000243- Bug #532646: object.__call__() will continue looking for the __call__
244 attribute on objects until one without one is found. This leads to recursion
245 when you take a class and set its __call__ attribute to an instance of the
246 class. Originally fixed for classic classes, but this fix is for new-style.
247 Removes the infinite_rec_3 crasher.
248
Georg Brandl24250812006-06-09 18:45:48 +0000249- The string and unicode methods startswith() and endswith() now accept
250 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
251
Brett Cannonde3b0522006-06-08 17:00:45 +0000252- Buffer objects, at the C level, never used the char buffer
253 implementation even when the char buffer for the wrapped object was
254 explicitly requested (originally returned the read or write buffer).
255 Now a TypeError is raised if the char buffer is not present but is
256 requested.
257
Georg Brandlddbaa662006-06-04 21:56:52 +0000258- Patch #1346214: Statements like "if 0: suite" are now again optimized
259 away like they were in Python 2.4.
260
Georg Brandlb7c8f542006-05-27 12:30:25 +0000261- Builtin exceptions are now full-blown new-style classes instead of
262 instances pretending to be classes, which speeds up exception handling
263 by about 80% in comparison to 2.5a2.
264
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000265- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
266 Unicode 4.1.
267
Georg Brandlf4ef1162006-05-26 18:03:31 +0000268- Patch #921466: sys.path_importer_cache is now used to cache valid and
269 invalid file paths for the built-in import machinery which leads to
270 fewer open calls on startup.
271
Tim Peters696cf432006-05-24 21:10:40 +0000272- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
273 of-2 bases. The largest speedup is for inputs with about 1000 decimal
274 digits. Conversion from non-power-of-2 bases remains quadratic-time in
275 the number of input digits (it was and remains linear-time for bases
276 2, 4, 8, 16 and 32).
277
Tim Petersb713ec22006-05-23 18:45:30 +0000278- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
279 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
280 an integer close to ``sys.maxint``. This was repaired by patch
281 #1335972, which also gives a nice speedup.
282
Richard Jonescebbefc2006-05-23 18:28:17 +0000283- Patch #1337051: reduced size of frame objects.
284
285- PyErr_NewException now accepts a tuple of base classes as its
286 "base" parameter.
287
Richard Jones7c88dcc2006-05-23 10:37:38 +0000288- Patch #876206: function call speedup by retaining allocated frame
289 objects.
290
Georg Brandl7b90e162006-05-18 07:01:27 +0000291- Bug #1462152: file() now checks more thoroughly for invalid mode
292 strings and removes a possible "U" before passing the mode to the
293 C library function.
294
Neal Norwitz1004a532006-05-15 07:17:23 +0000295- Patch #1488312, Fix memory alignment problem on SPARC in unicode
296
Neal Norwitz373f0a72006-05-15 07:04:36 +0000297- Bug #1487966: Fix SystemError with conditional expression in assignment
298
Martin v. Löwis879768d2006-05-11 13:28:43 +0000299- WindowsError now has two error code attributes: errno, which carries
300 the error values from errno.h, and winerror, which carries the error
301 values from winerror.h. Previous versions put the winerror.h values
302 (from GetLastError()) into the errno attribute.
303
Martin v. Löwis77736712006-05-04 05:51:03 +0000304- Patch #1475845: Raise IndentationError for unexpected indent.
305
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000306- Patch #1479181: split open() and file() from being aliases for each other.
307
Tim Peters44bd9862006-06-01 13:49:23 +0000308- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
309 methods were always silently ignored by dictionaries when comparing keys.
310 They are now passed through (except when using the C API function
311 ``PyDict_GetItem()``, whose semantics did not change).
312
313- Bug #1456209: In some obscure cases it was possible for a class with a
314 custom ``__eq__()`` method to confuse dict internals when class instances
315 were used as a dict's keys and the ``__eq__()`` method mutated the dict.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000318Extension Modules
319-----------------
320
Trent Mick960a3f82006-06-28 20:30:41 +0000321- Bug #1295808: expat symbols should be namespaced in pyexpat
322
323- Patch #1462338: Upgrade pyexpat to expat 2.0.0
324
Brett Cannon6ee7d012006-06-08 16:23:04 +0000325- Change binascii.hexlify to accept a read-only buffer instead of only a char
326 buffer and actually follow its documentation.
327
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000328- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
329
Nick Coghlanc649ec52006-05-29 12:43:05 +0000330- Patch #1478788 (modified version): The functional extension module has
331 been renamed to _functools and a functools Python wrapper module added.
332 This provides a home for additional function related utilities that are
333 not specifically about functional programming. See PEP 309.
334
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000335- Patch #1493701: performance enhancements for struct module.
336
Georg Brandl378d5922006-05-17 14:26:50 +0000337- Patch #1490224: time.altzone is now set correctly on Cygwin.
338
Georg Brandl8d3342b2006-05-16 07:38:27 +0000339- Patch #1435422: zlib's compress and decompress objects now have a
340 copy() method.
341
Andrew MacIntyre92913322006-06-13 15:04:24 +0000342- Patch #1454481: thread stack size is now tunable at runtime for thread
343 enabled builds on Windows and systems with Posix threads support.
344
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000345- On Win32, os.listdir now supports arbitrarily-long Unicode path names
346 (up to the system limit of 32K characters).
347
348- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
349 As a result, these functions now raise WindowsError instead of OSError.
350
Tim Peters7a822da2006-05-25 21:50:17 +0000351- ``time.clock()`` on Win64 should use the high-performance Windows
352 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
353 Windows platforms).
354
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000355- Calling Tk_Init twice is refused if the first call failed as that
356 may deadlock.
357
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000358- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
359 accept it without potentially using an uninitialized pointer.
360
361- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
362 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
363 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000364
Gregory P. Smith372b5832006-06-05 18:48:21 +0000365- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000366 [pybsddb project SF patch number 1466734]
367
Gregory P. Smith372b5832006-06-05 18:48:21 +0000368- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
369 parameter is supplied. [SF pybsddb bug #1477863]
370
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000371- bsddb: the __len__ method of a DB object has been fixed to return correct
372 results. It could previously incorrectly return 0 in some cases.
373 Fixes SF bug 1493322 (pybsddb bug 1184012).
374
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000375- bsddb: the bsddb.dbtables Modify method now raises the proper error and
376 aborts the db transaction safely when a modifier callback fails.
377 Fixes SF python patch/bug #1408584.
378
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000379- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000380 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000381 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
382 database calls that would previously deadlock. [SF python bug #775414]
383
Vinay Sajip28e57612006-07-01 10:45:20 +0000384- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000385
Walter Dörwald4994d952006-06-19 08:07:50 +0000386- Patch #1506645: add Python wrappers for the curses functions
387 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000388

390-------
391
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000392- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
393 functions.
394
Martin v. Löwis3798da02006-06-17 18:44:27 +0000395- Patch #812986: Update turtle output even if not tracing.
396
Vinay Sajip28e57612006-07-01 10:45:20 +0000397- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000398 Tkinter.BaseWidget.
399
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000400- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
401
Martin v. Löwis337487e2006-06-17 09:15:14 +0000402- Patch #763580: Add name and value arguments to Tkinter variable
403 classes.
404
Georg Brandl83cc0d02006-06-14 08:50:03 +0000405- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
406 mime.types file for determining MIME types.
407
Georg Brandl2605ca82006-06-14 06:08:31 +0000408- Bug #1339007: Shelf objects now don't raise an exception in their
409 __del__ method when initialization failed.
410
Martin v. Löwisd8251432006-06-14 05:21:04 +0000411- Patch #1455898: The MBCS codec now supports the incremental mode for
412 double-byte encodings.
413
Tim Peters43898b42006-06-14 04:09:25 +0000414- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
415 guarantee that adjacent triples in the return list always describe
416 non-adjacent blocks. Previously, a pair of matching blocks could end
417 up being described by multiple adjacent triples that formed a partition
418 of the matching pair.
419
Greg Ward0e0c9f42006-06-11 16:24:11 +0000420- Bug #1498146: fix optparse to handle Unicode strings in option help,
421 description, and epilog.
422
Greg Wardd1c797e2006-06-11 14:42:41 +0000423- Bug #1366250: minor optparse documentation error.
424
Greg Ward7f547402006-06-11 00:40:49 +0000425- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
426 clarify docs.
427
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000428- The wsgiref package has been added to the standard library.
429
Nick Coghlan676725d2006-06-08 13:54:49 +0000430- The functions update_wrapper() and wraps() have been added to the functools
431 module. These make it easier to copy relevant metadata from the original
432 function when writing wrapper functions.
433
Tim Petersd6a9eef2006-06-05 01:48:21 +0000434- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
435 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000436
Martin v. Löwis3f767792006-06-04 19:36:28 +0000437- Patch #1359618: Speed up charmap encoder by using a trie structure
438 for lookup.
439
Tim Petersd609b1a2006-06-02 23:22:51 +0000440- The functions in the ``pprint`` module now sort dictionaries by key
441 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
442 if and only if its display required more than one line, although that
443 wasn't documented. The new behavior increases predictability; e.g.,
444 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
445
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000446- Patch #1497027: try HTTP digest auth before basic auth in urllib2
447 (thanks for J. J. Lee).
448
Georg Brandl2b330372006-05-28 20:23:12 +0000449- Patch #1496206: improve urllib2 handling of passwords with respect to
450 default HTTP and HTTPS ports.
451
George Yoshidaf3c65de2006-05-28 16:39:09 +0000452- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
453
Bob Ippolito7298f272006-05-23 18:43:47 +0000454- Patch #1281707: speed up gzip.readline.
455
Georg Brandlb89316f2006-05-17 15:51:16 +0000456- Patch #1180296: Two new functions were added to the locale module:
457 format_string() to get the effect of "format % items" but locale-aware,
458 and currency() to format a monetary number with currency sign.
459
Georg Brandle3a25832006-05-17 14:56:04 +0000460- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
461 and several features added, such as speed and geometry control.
462
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000463- Patch #1488881: add support for external file objects in bz2 compressed
464 tarfiles.
465
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000466- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
467 stdout arguments, making it possible to redirect input and output
468 for remote debugging.
469
470- Patch #1484695: Update the tarfile module to version 0.8. This fixes
471 a couple of issues, notably handling of long file names using the
472 GNU LONGNAME extension.
473
474- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
475 new flag when ``name`` is already the name of an option flag.
476
477- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
478 package.
479
480- Patch #1472854: make the rlcompleter.Completer class usable on non-
481 UNIX platforms.
482
483- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
484
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000485- Bug #1472827: correctly escape newlines and tabs in attribute values in
486 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000516What's New in Python 2.5 alpha 2?
517=================================
518
519*Release date: 27-APR-2006*
520
521Core and builtins
522-----------------
523
Thomas Heller1b046642006-04-18 18:51:06 +0000524- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
525 by converting these apis from macros into exported functions again:
526
527 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
528 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
529 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
530 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
531 PyRun_String Py_CompileString
532
Martin v. Löwis45294a92006-04-18 06:24:08 +0000533- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
534
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000535- All uses of PyStructSequence_InitType have been changed to initialize
536 the type objects only once, even if the interpreter is initialized
537 multiple times.
538
Neal Norwitz61546162006-04-14 05:20:28 +0000539- Bug #1454485, array.array('u') could crash the interpreter. This was
540 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
541 to unicode when it didn't make sense. 'u#' now requires a unicode string.
542
543- Py_UNICODE is unsigned. It was always documented as unsigned, but
544 due to a bug had a signed value in previous versions.
545
Tim Peters3a5e8b12006-04-11 01:44:07 +0000546- Patch #837242: ``id()`` of any Python object always gives a positive
547 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
548 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000549 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000550 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000551
Tim Peters3a5e8b12006-04-11 01:44:07 +0000552 def __hash__(self):
553 return id(self) # WRONG
554
555 because a hash result must be a (short) Python int but it was always
556 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000557 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000558 was always usable as a hash value before this patch. That's no longer
559 necessarily so.
560
561- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000562 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000563 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000564 #1454844)
565
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000566- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
567 involving generators that have paused outside of any ``try`` or ``with``
568 blocks. (In 2.5a1, a paused generator that was part of a reference
569 cycle could not be garbage collected, regardless of whether it was
570 paused in a ``try`` or ``with`` block.)

583- Bug #1117761: bsddb.*open() no longer raises an exception when using
584 the cachesize parameter.
585
586- Bug #1149413: bsddb.*open() no longer raises an exception when using
587 a temporary db (file=None) with the 'n' flag to truncate on open.
588
589- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
590 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000591
Armin Rigoa9017c32006-04-19 11:50:27 +0000592- Patch #1062014: AF_UNIX sockets under Linux have a special
593 abstract namespace that is now fully supported.

596-------
597
Peter Astrand7d1d4362006-07-14 14:04:45 +0000598- Bug #1223937: subprocess.CalledProcessError reports the exit status
599 of the process using the returncode attribute, instead of
600 abusing errno.
601
Tim Peters711bf302006-04-25 03:31:36 +0000602- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
603 a doctest to be skipped (the code is not run, and the expected output
604 or exception is ignored).
605
Nick Coghlanda2268f2006-04-24 04:37:15 +0000606- Fixed contextlib.nested to cope with exceptions being raised and
607 caught inside exit handlers.
608
Greg Wardab05edc2006-04-23 03:47:58 +0000609- Updated optparse module to Optik 1.5.1 (allow numeric constants in
610 hex, octal, or binary; add ``append_const`` action; keep going if
611 gettext cannot be imported; added ``OptionParser.destroy()`` method;
612 added ``epilog`` for better help generation).
613
Tim Peters21fbd572006-04-21 21:18:10 +0000614- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
615 called from a thread spawned as a side effect of importing a module.
616
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000617- The pydoc module now supports documenting packages contained in
618 .zip or .egg files.
619
620- The pkgutil module now has several new utility functions, such
621 as ``walk_packages()`` to support working with packages that are either
622 in the filesystem or zip files.
623
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000624- The mailbox module can now modify and delete messages from
625 mailboxes, in addition to simply reading them. Thanks to Gregory
626 K. Johnson for writing the code, and to the 2005 Google Summer of
627 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000628
Tim Petersc7605f22006-04-17 21:12:33 +0000629- The ``__del__`` method of class ``local`` in module ``_threading_local``
630 returned before accomplishing any of its intended cleanup.
631
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000632- Patch #790710: Add breakpoint command lists in pdb.
633

639 Windows. Bug #1469163.
640
Phillip J. Eby47032112006-04-11 01:07:43 +0000641- The warnings, linecache, inspect, traceback, site, and doctest modules
642 were updated to work correctly with modules imported from zipfiles or

651
Skip Montanaro262fb922006-04-21 02:31:07 +0000652- The pstats.Stats class accepts an optional stream keyword argument to
653 direct output to an alternate file-like object.
654
Anthony Baxter51bcb682006-04-05 14:51:42 +0000655Build
656-----
657
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000658- The Makefile now has a reindent target, which runs reindent.py on
659 the library.
660
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000661- Patch #1470875: Building Python with MS Free Compiler
662
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000663- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000664
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000665- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
666 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000667 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000668 CXX from --with-cxx-main, see description in README.
669
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000670- Patch #1429775: Link extension modules with the shared libpython.
671
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000672- Fixed a libffi build problem on MIPS systems.
673
Tim Peters8931ff12006-05-13 23:28:20 +0000674- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
675 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
676 and "%zu" for unsigned integers of type ``size_t``.
677
Anthony Baxter51bcb682006-04-05 14:51:42 +0000678Tests
679-----
680
Nick Coghlanda2268f2006-04-24 04:37:15 +0000681- test_contextlib now checks contextlib.nested can cope with exceptions
682 being raised and caught inside exit handlers.
683
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000684- test_cmd_line now checks operation of the -m and -c command switches
685
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000686- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
687 it separately and by hand. It also wasn't cleaning up its changes to
688 the current Decimal context.
689
Thomas Woutersabd08882006-04-26 15:53:30 +0000690- regrtest.py now has a -M option to run tests that test the new limits of
691 containers, on 64-bit architectures. Running these tests is only sensible
692 on 64-bit machines with more than two gigabytes of memory. The argument
693 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000701Documentation
702-------------
703
Tim Petersb06d28c2006-05-12 01:57:59 +0000704- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
705
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000706- PEP 343: Added Context Types section to the library reference
707 and attempted to bring other PEP 343 related documentation into
708 line with the implementation and/or python-dev discussions.
709
Tim Peters8dc73d22006-04-24 02:03:16 +0000710- Bug #1337990: clarified that ``doctest`` does not support examples
711 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000714What's New in Python 2.5 alpha 1?
715=================================
716
Anthony Baxterebed3f62006-04-03 15:03:44 +0000717*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000718
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000719Core and builtins
720-----------------
721
Nick Coghlan43832302006-04-23 17:04:07 +0000722- PEP 338: -m command line switch now delegates to runpy.run_module
723 allowing it to support modules in packages and zipfiles
724
Martin v. Löwisc661b882006-04-20 04:54:23 +0000725- On Windows, .DLL is not an accepted file name extension for
726 extension modules anymore; extensions are only found if they
727 end in .PYD.
728
Martin v. Löwisea62d252006-04-03 10:56:49 +0000729- Bug #1421664: sys.stderr.encoding is now set to the same value as
730 sys.stdout.encoding.
731
Neal Norwitz92e212f2006-04-03 04:48:37 +0000732- __import__ accepts keyword arguments.
733
Georg Brandlccadf842006-03-31 18:54:53 +0000734- Patch #1460496: round() now accepts keyword arguments.
735
Anthony Baxter262c00a2006-03-30 10:53:17 +0000736- Fixed bug #1459029 - unicode reprs were double-escaped.
737
Hye-Shik Changd478f342006-03-23 12:32:36 +0000738- Patch #1396919: The system scope threads are reenabled on FreeBSD
739 5.4 and later versions.
740
Neal Norwitze98ccf62006-03-23 05:39:47 +0000741- Bug #1115379: Compiling a Unicode string with an encoding declaration
742 now gives a SyntaxError.
743
Georg Brandlabd1ff82006-03-18 07:59:59 +0000744- Previously, Python code had no easy way to access the contents of a
745 cell object. Now, a ``cell_contents`` attribute has been added
746 (closes patch #1170323).
747
Tim Peterscf79aac2006-03-16 01:14:46 +0000748- Patch #1123430: Python's small-object allocator now returns an arena to
749 the system ``free()`` when all memory within an arena becomes unused
750 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
751 freed. Some applications will see a drop in virtual memory size now,
752 especially long-running applications that, from time to time, temporarily
753 use a large number of small objects. Note that when Python returns an
754 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000755 platform C library will in turn return that memory to the operating system.
756 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000757 appears to be effective at least on Microsoft C and gcc-based systems.
758 Thanks to Evan Jones for hard work and patience.
759
Georg Brandl533ff6f2006-03-08 18:09:27 +0000760- Patch #1434038: property() now uses the getter's docstring if there is
761 no "doc" argument given. This makes it possible to legitimately use
762 property() as a decorator to produce a read-only property.
763
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000764- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
765 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
766 of requiring an int or long in slicing and a few other contexts, enabling
767 other objects (e.g. Numeric Python's integers) to be used as slice indices.
768
Neal Norwitz995acdf2006-03-07 05:01:00 +0000769- Fixed various bugs reported by Coverity's Prevent tool.
770
Brett Cannonbf364092006-03-01 04:25:17 +0000771- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
772 new exception base class, BaseException, which has a new message attribute.
773 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
774 Raising a string exception now raises a DeprecationWarning.
775
Thomas Woutersfb609f42006-02-28 16:37:25 +0000776- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
777 explicitly relative, using 'from .module import name' to mean 'from the same
778 package as this module is in. Imports without dots still default to the
779 old relative-then-absolute, unless 'from __future__ import
780 absolute_import' is used.
781
Brett Cannona7446e32006-02-27 23:39:10 +0000782- Properly check if 'warnings' raises an exception (usually when a filter set
783 to "error" is triggered) when raising a warning for raising string
784 exceptions.
785
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000786- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000787 The name was removed from Include/code.h.
788
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000789- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000790
Guido van Rossum1968ad32006-02-25 22:38:04 +0000791- Patch 1433928:
792 - The copy module now "copies" function objects (as atomic objects).
793 - dict.__getitem__ now looks for a __missing__ hook before raising
794 KeyError.
795
Tim Peters84ef21c2006-02-28 20:39:06 +0000796- PEP 343: with statement implemented. Needs ``from __future__ import
797 with_statement``. Use of 'with' as a variable will generate a warning.
798 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000799 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000800 The following objects have __context__ methods:
801 - The built-in file type.
802 - The thread.LockType type.
803 - The following types defined by the threading module:
804 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
805 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000806
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000807- Fix the encodings package codec search function to only search
808 inside its own package. Fixes problem reported in patch #1433198.
809
810 Note: Codec packages should implement and register their own
811 codec search function. PEP 100 has the details.
812
Tim Peters9ea89d22006-06-04 03:26:02 +0000813- PEP 353: Using ``Py_ssize_t`` as the index type.
814
815- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
816 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
817 now allow Python to make use of memory blocks exceeding 2**32 bytes for
818 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
819 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000820
Neal Norwitzfc76d632006-01-10 06:03:13 +0000821- Patch #1400181, fix unicode string formatting to not use the locale.
822 This is how string objects work. u'%f' could use , instead of .
823 for the decimal point. Now both strings and unicode always use periods.
824
Neal Norwitz671b9e32006-01-09 07:07:12 +0000825- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
826 configure would break checking curses.h.
827
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000828- Bug #959576: The pwd module is now builtin. This allows Python to be
829 built on UNIX platforms without $HOME set.
830
Neal Norwitzc10978f2005-12-19 06:07:16 +0000831- Bug #1072182, fix some potential problems if characters are signed.
832
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000833- Bug #889500, fix line number on SyntaxWarning for global declarations.
834
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000835- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
836
Neal Norwitze7214a12005-12-18 05:03:17 +0000837- Support for converting hex strings to floats no longer works.
838 This was not portable. float('0x3') now raises a ValueError.
839
Barry Warsaw2a38a862005-12-18 01:27:35 +0000840- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000841 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000842 is now displayed in interactive prompt banner.
843
Georg Brandlfa166682005-12-17 21:45:17 +0000844- Implementation of PEP 341 - Unification of try/except and try/finally.
845 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000846 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000847
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000848- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
849 now encodes backslash correctly.
850
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000851- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
852
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000853- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000854 and long longs.
855
Neal Norwitz67715f02005-11-09 06:59:35 +0000856- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000857 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000858 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000859
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000860- Replaced most Unicode charmap codecs with new ones using the
861 new Unicode translate string feature in the builtin charmap
862 codec; the codecs were created from the mapping tables available
863 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
864 encodings now include a mapping for the Apple logo)
865
Tim Peterse3547fd2005-12-16 23:13:57 +0000866- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000867
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000868- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000869
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000870- A new AST parser implementation was completed. The abstract
871 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000872 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000873
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000874- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000875 The following code now raises a SyntaxError: foo(a = i for i in range(10))
876
Neal Norwitz708e51a2005-10-03 04:48:15 +0000877- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
878
Neal Norwitz11bd1192005-10-03 00:54:56 +0000879- SF Bug #887946: fix segfault when redirecting stdin from a directory.
880 Provide a warning when a directory is passed on the command line.
881
Neal Norwitz40d37812005-10-02 01:48:49 +0000882- Fix segfault with invalid coding.
883
884- SF bug #772896: unknown encoding results in MemoryError.
885
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000886- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000887 supported a __len__() method which evaluated to False when the iterator
888 was empty.
889
Guido van Rossum630db602005-09-20 18:49:54 +0000890- On 64-bit platforms, when __len__() returns a value that cannot be
891 represented as a C int, raise OverflowError.
892
Skip Montanarof8948ca2005-09-19 03:54:46 +0000893- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000894 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000895
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000896- SF bug #893549: parsing keyword arguments was broken with a few format
897 codes.
898
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000899- Changes donated by Elemental Security to make it work on AIX 5.3
900 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
901 bug #105470: test_pwd fails on 64bit system (Opteron).
902
Guido van Rossum539c6622005-09-14 17:49:54 +0000903- Changes donated by Elemental Security to make it work on HP-UX 11 on
904 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
905
Georg Brandl4550b8d2005-08-26 06:43:52 +0000906- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000907 (fixes bug #1119418).
908
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000909- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
910
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000911- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
912 exceptions that cause a function to exit.
913
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000914- The implementation of set() and frozenset() was revised to use its
915 own internal data structure. Memory consumption is reduced by 1/3
916 and there are modest speed-ups as well. The API is unchanged.
917
Tim Petersde7990b2005-07-17 23:45:23 +0000918- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
919
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000920- SF bug #1229429: PyObject_CallMethod failed to decrement some
921 reference counts in some error exit cases.
922
Tim Petersecc6e6a2005-07-10 22:30:55 +0000923- SF bug #1185883: Python's small-object memory allocator took over
924 a block managed by the platform C library whenever a realloc specified
925 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000926 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000927 portable way to copy data from the C-managed block into Python's
928 small-object space without risking a memory fault. Python's small-object
929 realloc now leaves such blocks under the control of the platform C
930 realloc.
931
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000932- SF bug #1232517: An overflow error was not detected properly when
933 attempting to convert a large float to an int in os.utime().
934
Raymond Hettinger3296e692005-06-29 23:29:56 +0000935- SF bug #1224347: hex longs now print with lowercase letters just
936 like their int counterparts.
937
Michael W. Hudson188d4362005-06-20 16:52:57 +0000938- SF bug #1163563: the original fix for bug #1010677 ("thread Module
939 Breaks PyGILState_Ensure()") broke badly in the case of multiple
940 interpreter states; back out that fix and do a better job (see
941 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
942 for a longer write-up of the problem).
943
Michael W. Hudsondf888462005-06-03 14:41:55 +0000944- SF patch #1180995: marshal now uses a binary format by default when
945 serializing floats.
946
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000947- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
948 the routines that promise to produce IEEE 754 binary representations
949 of floats now simply copy bytes around.
950
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000951- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
952 278.
953
Brett Cannonc3647ac2005-04-26 03:45:26 +0000954- patch #1109424: int, long, float, complex, and unicode now check for the
955 proper magic slot for type conversions when subclassed. Previously the
956 magic slot was ignored during conversion. Semantics now match the way
957 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000958 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000959 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000960 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000961
Barry Warsawc8d907c2005-04-19 23:43:40 +0000962- Descriptors defined in C with a PyGetSetDef structure, where the setter is
963 NULL, now raise an AttributeError when attempting to set or delete the
964 attribute. Previously a TypeError was raised, but this was inconsistent
965 with the equivalent pure-Python implementation.
966
Michael W. Hudson774479c2005-04-18 08:46:17 +0000967- It is now safe to call PyGILState_Release() before
968 PyEval_InitThreads() (note that if there is reason to believe there
969 are multiple threads around you still must call PyEval_InitThreads()
970 before using the Python API; this fix is for extension modules that
971 have no way of knowing if Python is multi-threaded yet).
972
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000973- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
974 disabled caused a crash.
975
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000976- Bug #1165306: instancemethod_new allowed the creation of a method
977 with im_class == im_self == NULL, which caused a crash when called.
978
Tim Petersecc6e6a2005-07-10 22:30:55 +0000979- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000980 fixes the crash seen in bug #1165761
981
Raymond Hettinger96229b12005-03-11 06:49:40 +0000982- Added two new builtins, any() and all().
983
Brett Cannon409d8f22005-03-05 06:47:57 +0000984- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000985 (e.g., ``class C(): pass`` is no longer a syntax error).
986 Patch #1176012 added support to the 'parser' module and 'compiler' package
987 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000988
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000989- Patch #1115086: Support PY_LONGLONG in structmember.
990
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000991- Bug #1155938: new style classes did not check that __init__() was
992 returning None.
993
Tim Petersecc6e6a2005-07-10 22:30:55 +0000994- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000995 ('\') with a specific error message.
996
Martin v. Löwisff232d72005-03-03 09:24:38 +0000997- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
998
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000999- Bug #1124295: the __name__ attribute of file objects was
1000 inadvertently made inaccessible in restricted mode.
1001
Tim Petersecc6e6a2005-07-10 22:30:55 +00001002- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001003 an ferror() call.
1004
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001005- min() and max() now support key= arguments with the same meaning as in
1006 list.sort().
1007
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001008- The peephole optimizer now performs simple constant folding in expressions:
1009 (2+3) --> (5).
1010
Raymond Hettingera422c342005-01-11 03:03:27 +00001011- set and frozenset objects can now be marshalled. SF #1098985.
1012
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001013- Bug #1077106: Poor argument checking could cause memory corruption
1014 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001015
Jeremy Hyltonab630502005-02-04 18:44:06 +00001016- The parser did not complain about future statements in illegal
1017 positions. It once again reports a syntax error if a future
1018 statement occurs after anything other than a doc string.
1019
Neil Schemenauercf52c072005-08-12 17:34:58 +00001020- Change the %s format specifier for str objects so that it returns a
1021 unicode instance if the argument is not an instance of basestring and
1022 calling __str__ on the argument returns a unicode instance.
1023
Tim Petersf4e69282006-02-27 17:15:31 +00001024- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1025 current thread state when the auto-GIL-state machinery knows about
1026 it (since the thread state is being deleted, continuing to remember it
1027 can't help, but can hurt if another thread happens to get created with
1028 the same thread id).
1029
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001030Extension Modules

1047
1048- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1049
1050- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001051 is deprecated. The undocumented re.engine variable no longer exists.
1052

1055
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001056- The unicodedata module was updated to the 4.1 version of the Unicode
1057 database. The 3.2 version is still available as unicodedata.db_3_2_0
1058 for applications that require this specific version (such as IDNA).
1059
Neal Norwitzb62c4332006-03-04 18:35:47 +00001060- The timing module is no longer built by default. It was deprecated
1061 in PEP 4 in Python 2.0 or earlier.
1062
Guido van Rossum1968ad32006-02-25 22:38:04 +00001063- Patch 1433928: Added a new type, defaultdict, to the collections module.
1064 This uses the new __missing__ hook behavior added to dict (see above).
1065
Georg Brandldbd83392006-02-20 09:42:33 +00001066- Bug #854823: socketmodule now builds on Sun platforms even when

1076 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1077 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1078
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001079- Patch #1422385: The nis module now supports access to domains other

1081
Martin v. Löwis14694662006-02-03 12:54:16 +00001082- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1083 are reported, the limit on path name lengths is removed, and stat reports
1084 WindowsError now (instead of OSError).
1085
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001086- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

1161 the request code argument, which results in more C-like behaviour
1162 for large or negative values.
1163
Tim Petersecc6e6a2005-07-10 22:30:55 +00001164- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001204- the cPickle module no longer accepts the deprecated None option in the
1205 args tuple returned by __reduce__().
1206
Raymond Hettingerb2594052004-12-05 09:25:51 +00001207- itertools.islice() now accepts None for the start and step arguments.

1218-------
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001219
1220- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1221 been renamed to have only a single underscore prefix. This was done to
1222 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001223
Nick Coghlan43832302006-04-23 17:04:07 +00001224- PEP 338: new module runpy defines a run_module function to support
1225 executing modules which provide access to source code or a code object
1226 via the PEP 302 import mechanisms.
1227
Anthony Baxter93f5b932006-04-03 08:05:07 +00001228- The email module's parsedate_tz function now sets the daylight savings
1229 flag to -1 (unknown) since it can't tell from the date whether it should

1236 in attribute values.
1237
Anthony Baxterc51ee692006-04-01 00:57:31 +00001238- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001239 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001240 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001241 module will not be built.
1242
Tim Petersc17976e2006-04-01 00:26:53 +00001243- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1244 aren't officially supported here, and trying to use them will probably
1245 raise an exception some day. But dicts have been allowed, and "mostly
1246 worked", so support for them won't go away without warning.
1247
Georg Brandl338ef7d2006-03-31 18:42:16 +00001248- Bug #1445068: getpass.getpass() can now be given an explicit stream
1249 argument to specify where to write the prompt.
1250
Georg Brandl22ec80b2006-03-31 18:25:44 +00001251- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1260 to make it easier to monitor when daemon threads have completed
1261 processing all enqueued tasks. Patch #1455676.
1262
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001263- popen2.Popen objects now preserve the command in a .cmd attribute.
1264
Thomas Hellerc61c0492006-03-22 10:09:27 +00001265- Added the ctypes ffi package.
1266
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001267- email 4.0 package now integrated. This is largely the same as the email 3.0
1268 package that was included in Python 2.3, except that PEP 8 module names are
1269 now used (e.g. mail.message instead of email.Message). The MIME classes
1270 have been moved to a subpackage (e.g. email.mime.text instead of
1271 email.MIMEText). The old names are still supported for now. Several
1272 deprecated Message methods have been removed and lots of bugs have been
1273 fixed. More details can be found in the email package documentation.
1274
Walter Dörwald40108c92006-03-27 08:15:44 +00001275- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1276 (a subclass of tuple) that provides incremental decoders and encoders
1277 (a way to use stateful codecs without the stream API). Python functions
1278 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1279 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1280 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001281
Walter Dörwald067db482006-03-15 22:17:27 +00001282- Patch #1359365: Calling next() on a closed StringIO.String object raises
1283 a ValueError instead of a StopIteration now (like file and cString.String do).
1284 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1285 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001286
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001287- A regrtest option -w was added to re-run failed tests in verbose mode.

1293 grew an optional 'generation' argument.
1294

1299 and helpful context managers nested() and closing().
1300

1304 not allowed by the specs.
1305
Georg Brandlc98eeed2006-02-19 14:57:47 +00001306- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00001335 specifications, raises IOErrors when proxies for unsupported protocols
1336 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001359 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1360 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1361 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1362 Ronald L. Rivest offered this advice for Python:
1363
1364 "The consensus of researchers in this area (at least as
1365 expressed at the NIST Hash Function Workshop 10/31/05),
1366 is that SHA-256 is a good choice for the time being, but
1367 that research should continue, and other alternatives may
1368 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001369
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001370- Added a subset of Fredrik Lundh's ElementTree package. Available

1448
Georg Brandl9e43acf2005-07-04 17:16:07 +00001449- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1450 as this can cause problems with apps closing all file descriptors.
1451
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001452- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001453 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001454

1456
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001457- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1458 error messages.
1459
Georg Brandl379f99d2005-06-26 21:09:38 +00001460- Bug #1108948: Cookie.py produced invalid JavaScript code.
1461
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001462- The tokenize module now detects and reports indentation errors.
1463 Bug #1224621.
1464
Raymond Hettinger68c04532005-06-10 11:05:19 +00001465- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001466 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001467 the generate_tokens() function now accepts a callable argument that
1468 terminates by raising StopIteration.
1469
Georg Brandl9166e1a2005-06-04 09:20:03 +00001470- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1471
Georg Brandl268e61c2005-06-03 14:28:50 +00001472- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1473 component of the path.
1474
Skip Montanaro174dd222005-05-14 20:54:16 +00001475- Patch #1120353: The xmlrpclib module provides better, more transparent,
1476 support for datetime.{datetime,date,time} objects. With use_datetime set
1477 to True, applications shouldn't have to fiddle with the DateTime wrapper
1478 class at all.
1479
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001480- distutils.commands.upload was added to support uploading distribution
1481 files to PyPI.
1482
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001483- distutils.commands.register now encodes the data as UTF-8 before posting
1484 them to PyPI.
1485
Raymond Hettinger267b8682005-03-27 10:47:39 +00001486- decimal operator and comparison methods now return NotImplemented
1487 instead of raising a TypeError when interacting with other types. This
1488 allows other classes to implement __radd__ style methods and have them
1489 work as expected.
1490
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001491- Bug #1163325: Decimal infinities failed to hash. Attempting to
1492 hash a NaN raised an InvalidOperation instead of a TypeError.
1493
Tim Petersecc6e6a2005-07-10 22:30:55 +00001494- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001495 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1496

1528
Guido van Rossumd0641422005-02-03 15:01:24 +00001529- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1530 disables recursive traversal through instance attributes, which can
1531 be exploited in various ways.
1532
Tim Peterse3547fd2005-12-16 23:13:57 +00001533- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001534 flags on the HTTP listening socket.
1535
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001536- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1537 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1538
Tim Peterse3547fd2005-12-16 23:13:57 +00001539- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001540 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1541
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001542- Bug #1110478: Revert os.environ.update to do putenv again.
1543
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001544- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1545
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001546- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1547
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001548- Enhancements to the csv module:
1549
1550 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001551 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001552 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001553 + Dialect parameter parsing has been re-implemented to improve error
1554 reporting.
1555 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1556 dictates.
1557 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001558 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001559 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001560 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1561 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001562 + reader now allows \r characters to be quoted (previously it only allowed
1563 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001564 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001565 + Dialect classes passed to the module are no longer instantiated by
1566 the module before being parsed (the former validation scheme required
1567 this, but the mechanism was unreliable).
1568 + The dialect registry now contains instances of the internal
1569 C-coded dialect type, rather than references to python objects.
1570 + the internal c-coded dialect type is now immutable.
1571 + register_dialect now accepts the same keyword dialect specifications
1572 as the reader and writer, allowing the user to register dialects
1573 without first creating a dialect class.
1574 + a configurable limit to the size of parsed fields has been added -
1575 previously, an unmatched quote character could result in the entire
1576 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001577 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001578 the parser field size limit (returning the former limit). The initial
1579 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001580 + A line_num attribute has been added to the reader object, which tracks
1581 the number of lines read from the source iterator. This is not
1582 the same as the number of records returned, as records can span
1583 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001584 + reader and writer objects were not being registered with the cyclic-GC.
1585 This has been fixed.
1586
Brett Cannone6539c42005-01-08 02:43:53 +00001587- _DummyThread objects in the threading module now delete self.__block that is
1588 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1589 lock primitives tend to be limited in number and thus should not be wasted on
1590 a _DummyThread object. Fixes bug #1089632.
1591
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001592- The imghdr module now detects Exif files.
1593
Raymond Hettinger6065d322004-12-20 23:51:53 +00001594- StringIO.truncate() now correctly adjusts the size attribute.
1595 (Bug #951915).
1596
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001597- locale.py now uses an updated locale alias table (built using
1598 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1599 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001600 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001601
Raymond Hettinger3557f422004-12-07 12:02:02 +00001602- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1603
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001604- the pickle module no longer accepts the deprecated None option in the
1605 args tuple returned by __reduce__().
1606
Brett Cannon84667c02004-12-07 03:25:18 +00001607- optparse now optionally imports gettext. This allows its use in setup.py.
1608
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001609- the pickle module no longer uses the deprecated bin parameter.
1610
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001611- the shelve module no longer uses the deprecated binary parameter.
1612
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001613- the pstats module no longer uses the deprecated ignore() method.
1614
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001615- the filecmp module no longer uses the deprecated use_statcache argument.
1616
Raymond Hettinger664347b2004-12-04 21:21:53 +00001617- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1618 extended or overridden by subclasses. Formerly, the subclassed method would
1619 be ignored by the rest of the module. (Bug #1078905).
1620
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001621- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001622 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001623
Walter Dörwald36733692004-12-22 12:50:50 +00001624- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1625 once when a size argument is given. This prevents a buffer overflow in the
1626 tokenizer with very long source lines.
1627
Barry Warsaw538561e2006-01-01 21:48:54 +00001628- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1629 immediately after creating the object, without any intervening
1630 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001631
Skip Montanaro05885812005-01-16 20:48:27 +00001632- The reconvert.quote function can now emit triple-quoted strings. The
1633 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001634
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001635- ``UserString.MutableString`` now supports negative indices in
1636 ``__setitem__`` and ``__delitem__``
1637
Greg Ward40407942005-03-05 02:53:17 +00001638- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1639 correctly.
1640
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001641- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1642 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1643 character even if the user has passed a size parameter to get a proper
1644 line ending. Remove the special handling of a "\r\n" that has been split
1645 between two lines.
1646
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001647- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1648 about illegal code points. The codec now supports PEP 293 style error
1649 handlers.
1650
Walter Dörwald78a78b02005-09-01 12:04:29 +00001651- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001652 from the input stream, so that the output is a byte string in the correct
1653 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001654
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001655- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1656 considering it exactly like a '*'.
1657
Walter Dörwald007f8df2005-10-09 19:42:27 +00001658- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1659 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001660
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001661- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1662
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001663- Patch #1413711: Certain patterns of differences were making difflib
1664 touch the recursion limit.
1665
Walter Dörwald58917a62006-03-31 15:26:22 +00001666- Bug #947906: An object oriented interface has been added to the calendar
1667 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001668 called as a script (e.g. via ``python -mcalendar``). Localized month and
1669 weekday names can be ouput (even if an exotic encoding is used) using
1670 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001671

1695 vulnerability in zlib 1.2.1 and 1.2.2.
1696
Brett Cannon08cd5982005-04-24 22:26:38 +00001697- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1698 flags that change binary compatibility. Changes were also made to
1699 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001700 compilation of the interpreter and of C extensions through distutils.

1705
Martin v. Löwise2713be2005-03-08 15:03:08 +00001706- Bug #1158607: Build with --disable-unicode again.
1707
Brett Cannon46d96232005-02-16 00:07:19 +00001708- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1709 defined. Discovered as a result of not being able to build on OS X.
1710
Brett Cannon516592f2004-12-07 00:42:59 +00001711- setup.py now uses the directories specified in LDFLAGS using the -L option
1712 and in CPPFLAGS using the -I option for adding library and include
1713 directories, respectively, for compiling extension modules against. This has
1714 led to the core being compiled using the values in CPPFLAGS. It also removes
1715 the need for the special-casing of both DarwinPorts and Fink for darwin since
1716 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1717 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1718 Fink, ``-I/opt/local/include`` for DarwinPorts).
1719
Brett Cannon43802422005-02-10 20:48:03 +00001720- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1721 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1722 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1723 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001725C API
1726-----
1727
Tim Petersc9d78aa2006-03-26 23:27:58 +00001728- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1729 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1730 is obtained via the ``PyObject_`` family, it must be released via the
1731 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1732 always been officially true, but when Python's small-object allocator was
1733 introduced, an attempt was made to cater to a few extension modules
1734 discovered at the time that obtained memory via ``PyObject_New`` but
1735 released it via ``PyMem_DEL``. It's years later, and if such code still
1736 exists it will fail now (probably with segfaults, but calling wrong
1737 low-level memory management functions can yield many symptoms).
1738
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001739- Added a C API for set and frozenset objects.
1740
Raymond Hettinger66517482004-12-03 11:45:13 +00001741- Removed PyRange_New().
1742
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001743- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1744 mapping argument now. This string is used as a mapping table. Byte values
1745 greater than the length of the string and 0xFFFE are treated as undefined
1746 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001754- Patch #1276356: New resource "urlfetch" is implemented. This enables
1755 even impatient people to run tests that require remote files.
