11
12Core and builtins
13-----------------
14
Neal Norwitze1fdb322006-07-21 05:32:28 +000015- Fix some potential crashes found with failmalloc.
16
Neal Norwitze7563102006-07-17 01:00:16 +000017- Fix warnings reported by Klocwork's static analysis tool.
18
Neal Norwitz84be93b2006-07-16 01:50:38 +000019- Bug #1512814, Fix incorrect lineno's when code within a function
20 had more than 255 blank lines.
21
Georg Brandl9dceedb2006-07-12 15:31:17 +000022- Patch #1521179: Python now accepts the standard options ``--help`` and
23 ``--version`` as well as ``/?`` on Windows.
24
Neal Norwitza1f10902006-07-12 07:28:29 +000025- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
26 again. Fixing this problem required changing the .pyc magic number.
27 This means that .pyc files generated before 2.5c1 will be regenerated.
28
Tim Peters112aad32006-07-19 00:03:19 +000029- Bug #1524317: Compiling Python ``--without-threads`` failed.
30 The Python core compiles again then, and, in a build without threads, the
31 new ``sys._current_frames()`` returns a dictionary with one entry,
32 mapping the faux "thread id" 0 to the current frame.

35-------
36
Martin v. Löwis426f4a12006-07-18 17:46:31 +000037- Patch #1524429: Use repr() instead of backticks in Tkinter again.
38
Brett Cannoncaebe222006-07-18 04:41:36 +000039- Bug #1520914: Change time.strftime() to accept a zero for any position in its
40 argument tuple. For arguments where zero is illegal, the value is forced to
41 the minimum value that is correct. This is to support an undocumented but
42 common way people used to fill in inconsequential information in the time
43 tuple pre-2.4.
44
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000045- Patch #1220874: Update the binhex module for Mach-O.

48-----------------
49
Thomas Hellerce049a02006-07-14 17:51:14 +000050- Patch #1521817: Index range checking on ctypes arrays containing
51 exactly one element enabled again. This allows iterating over these
52 arrays, without the need to check the array size before.
53
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000054- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000055 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000056 /dev/null in certain cases; this is now fixed.
57
Thomas Heller47d7a062006-07-12 08:43:47 +000058- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
59 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000060
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000061- Because of a misspelled preprocessor symbol, ctypes was always
62 compiled without thread support; this is now fixed.

69Core and builtins
70-----------------
71
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000072- Bug #1441486: The literal representation of -(sys.maxint - 1)
73 again evaluates to a int object, not a long.
74
Neil Schemenauer0e07b602006-07-09 16:16:34 +000075- Bug #1501934: The scope of global variables that are locally assigned
76 using augmented assignment is now correctly determined.
77
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000078- Bug #927248: Recursive method-wrapper objects can now safely
79 be released.
80
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000081- Bug #1417699: Reject locale-specific decimal point in float()
82 and atof().
83
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000084- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
85 omit a default "error" argument for NULL pointer. This allows
86 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000087
Neal Norwitzfb48afa2006-07-08 05:31:37 +000088- Bug #1519018: 'as' is now validated properly in import statements.
89
Neal Norwitz28746ab2006-07-09 22:14:42 +000090- On 64 bit systems, int literals that use less than 64 bits are
91 now ints rather than longs.
92
Neal Norwitzed657552006-07-10 00:04:44 +000093- Bug #1512814, Fix incorrect lineno's when code at module scope
94 started after line 256.
95
Tim Peters32a83612006-07-10 21:08:24 +000096- New function ``sys._current_frames()`` returns a dict mapping thread
97 id to topmost thread stack frame. This is for expert use, and is
98 especially useful for debugging application deadlocks. The functionality
99 was previously available in Fazal Majid's ``threadframe`` extension
100 module, but it wasn't possible to do this in a wholly threadsafe way from
101 an extension.
102
Georg Brandlad29e632006-06-21 17:45:17 +0000103Library

Martin v. Löwis8d656812006-07-10 07:23:48 +0000109 environment variable to be set in order to the SDK environment
110 for finding the compiler, include files, etc.
111
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000112- Bug #1515998: Properly generate logical ids for files in bdist_msi.
113
Nick Coghlan2d792252006-07-06 13:47:18 +0000114- warnings.py now ignores ImportWarning by default
115
Thomas Woutersadd19112006-07-05 11:03:49 +0000116- string.Template() now correctly handles tuple-values. Previously,
117 multi-value tuples would raise an exception and single-value tuples would
118 be treated as the value they contain, instead.
119
Martin v. Löwisede77f52006-07-03 13:01:35 +0000120- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
121 even if some data are received.
122
Martin v. Löwis45482392006-07-03 12:28:58 +0000123- Bug #1267547: Put proper recursive setup.py call into the

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000130 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000131
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000132- Bug #1514703: Only setup canvas window in turtle when the canvas
133 is created.
134
Martin v. Löwis7596e832006-07-01 15:33:37 +0000135- Bug #1513223: .close() of a _socketobj now releases the underlying
136 socket again, which then gets closed as it becomes unreferenced.
137
Fred Drake10497c82006-06-29 02:57:48 +0000138- Bug #1504333: Make sgmllib support angle brackets in quoted
139 attribute values.
140
141- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
142 sgmllib ('[' and ']' were not accepted).
143
Georg Brandl1be63af2006-06-28 20:23:25 +0000144- Fix a bug in the turtle module's end_fill function.
145
Brett Cannon53ab5b72006-06-22 16:49:14 +0000146- Bug #1510580: The 'warnings' module improperly required that a Warning
147 category be either a types.ClassType and a subclass of Warning. The proper
148 check is just that it is a subclass with Warning as the documentation states.
149
Georg Brandlad29e632006-06-21 17:45:17 +0000150- The compiler module now correctly compiles the new try-except-finally
151 statement (bug #1509132).
152
Neal Norwitz60373cd2006-06-22 06:30:50 +0000153- The wsgiref package is now installed properly on Unix.
154
Vinay Sajip28e57612006-07-01 10:45:20 +0000155- A bug was fixed in logging.config.fileConfig() which caused a crash on
156 shutdown when fileConfig() was called multiple times.
157
Gerhard Häring762fbd32006-07-02 17:48:30 +0000158- The sqlite3 module did cut off data from the SQLite database at the first
159 null character before sending it to a custom converter. This has been fixed
160 now.
161
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000162Extension Modules
163-----------------
164
Tim Peters112aad32006-07-19 00:03:19 +0000165- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
166 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
167 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000168
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000169- Assigning None to pointer type fields in ctypes structures possible
170 overwrote the wrong fields, this is fixed now.
171
172- Fixed a segfault in _ctypes when ctypes.wintypes were imported
173 on non-Windows platforms.
174
175- Bug #1518190: The ctypes.c_void_p constructor now accepts any
176 integer or long, without range checking.
177
178- Patch #1517790: It is now possible to use custom objects in the ctypes
179 foreign function argtypes sequence as long as they provide a from_param
180 method, no longer is it required that the object is a ctypes type.
181
182- The '_ctypes' extension module now works when Python is configured
183 with the --without-threads option.
184
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000185- Bug #1513646: os.access on Windows now correctly determines write
186 access, again.
187
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000188- Bug #1512695: cPickle.loads could crash if it was interrupted with
189 a KeyboardInterrupt.
190
Neal Norwitza12aa882006-07-06 06:45:08 +0000191- Bug #1296433: parsing XML with a non-default encoding and
192 a CharacterDataHandler could crash the interpreter in pyexpat.
193
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000194- Patch #1516912: improve Modules support for OpenVMS.
195

197-----
198
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000199- Automate Windows build process for the Win64 SSL module.
200
Tim Peters32a83612006-07-10 21:08:24 +0000201- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000202 Previously, the slight difference could cause compilation errors of the
203 'zlib' module on systems with more than one version of zlib.
204
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000205- The MSI compileall step was fixed to also support a TARGETDIR
206 with spaces in it.
207
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000208- Bug #1517388: sqlite3.dll is now installed on Windows independent
209 of Tcl/Tk.
210
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000211- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000212 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000213
Neal Norwitzb15ac312006-06-29 04:10:08 +0000214Tests
215-----
216
217- Call os.waitpid() at the end of tests that spawn child processes in order
218 to minimize resources (zombies).
219
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000220Documentation
221-------------
222
Nick Coghlan2d792252006-07-06 13:47:18 +0000223- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
224 documentation for the warnings module.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000230What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000231================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000232
Anthony Baxterd1136802006-06-19 12:04:15 +0000233*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000234
235Core and builtins
236-----------------
237
Georg Brandla56b9152006-06-19 06:35:54 +0000238- Patch #1507676: Error messages returned by invalid abstract object operations
239 (such as iterating over an integer) have been improved and now include the
240 type of the offending object to help with debugging.
241
Brett Cannonea3912b2006-06-13 21:46:41 +0000242- Bug #992017: A classic class that defined a __coerce__() method that returned
243 its arguments swapped would infinitely recurse and segfault the interpreter.
244
Neal Norwitz909eb122006-06-12 02:13:21 +0000245- Fix the socket tests so they can be run concurrently.
246
Neal Norwitzb9845e72006-06-12 02:11:18 +0000247- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000248 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000249
Brett Cannon22565aa2006-06-09 22:31:23 +0000250- Bug #532646: object.__call__() will continue looking for the __call__
251 attribute on objects until one without one is found. This leads to recursion
252 when you take a class and set its __call__ attribute to an instance of the
253 class. Originally fixed for classic classes, but this fix is for new-style.
254 Removes the infinite_rec_3 crasher.
255
Georg Brandl24250812006-06-09 18:45:48 +0000256- The string and unicode methods startswith() and endswith() now accept
257 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
258
Brett Cannonde3b0522006-06-08 17:00:45 +0000259- Buffer objects, at the C level, never used the char buffer
260 implementation even when the char buffer for the wrapped object was
261 explicitly requested (originally returned the read or write buffer).
262 Now a TypeError is raised if the char buffer is not present but is
263 requested.
264
Georg Brandlddbaa662006-06-04 21:56:52 +0000265- Patch #1346214: Statements like "if 0: suite" are now again optimized
266 away like they were in Python 2.4.
267
Georg Brandlb7c8f542006-05-27 12:30:25 +0000268- Builtin exceptions are now full-blown new-style classes instead of
269 instances pretending to be classes, which speeds up exception handling
270 by about 80% in comparison to 2.5a2.
271
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000272- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
273 Unicode 4.1.
274
Georg Brandlf4ef1162006-05-26 18:03:31 +0000275- Patch #921466: sys.path_importer_cache is now used to cache valid and
276 invalid file paths for the built-in import machinery which leads to
277 fewer open calls on startup.
278
Tim Peters696cf432006-05-24 21:10:40 +0000279- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
280 of-2 bases. The largest speedup is for inputs with about 1000 decimal
281 digits. Conversion from non-power-of-2 bases remains quadratic-time in
282 the number of input digits (it was and remains linear-time for bases
283 2, 4, 8, 16 and 32).
284
Tim Petersb713ec22006-05-23 18:45:30 +0000285- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
286 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
287 an integer close to ``sys.maxint``. This was repaired by patch
288 #1335972, which also gives a nice speedup.
289
Richard Jonescebbefc2006-05-23 18:28:17 +0000290- Patch #1337051: reduced size of frame objects.
291
292- PyErr_NewException now accepts a tuple of base classes as its
293 "base" parameter.
294
Richard Jones7c88dcc2006-05-23 10:37:38 +0000295- Patch #876206: function call speedup by retaining allocated frame
296 objects.
297
Georg Brandl7b90e162006-05-18 07:01:27 +0000298- Bug #1462152: file() now checks more thoroughly for invalid mode
299 strings and removes a possible "U" before passing the mode to the
300 C library function.
301
Neal Norwitz1004a532006-05-15 07:17:23 +0000302- Patch #1488312, Fix memory alignment problem on SPARC in unicode
303
Neal Norwitz373f0a72006-05-15 07:04:36 +0000304- Bug #1487966: Fix SystemError with conditional expression in assignment
305
Martin v. Löwis879768d2006-05-11 13:28:43 +0000306- WindowsError now has two error code attributes: errno, which carries
307 the error values from errno.h, and winerror, which carries the error
308 values from winerror.h. Previous versions put the winerror.h values
309 (from GetLastError()) into the errno attribute.
310
Martin v. Löwis77736712006-05-04 05:51:03 +0000311- Patch #1475845: Raise IndentationError for unexpected indent.
312
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000313- Patch #1479181: split open() and file() from being aliases for each other.
314
Tim Peters44bd9862006-06-01 13:49:23 +0000315- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
316 methods were always silently ignored by dictionaries when comparing keys.
317 They are now passed through (except when using the C API function
318 ``PyDict_GetItem()``, whose semantics did not change).
319
320- Bug #1456209: In some obscure cases it was possible for a class with a
321 custom ``__eq__()`` method to confuse dict internals when class instances
322 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
323 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000325Extension Modules
326-----------------
327
Trent Mick960a3f82006-06-28 20:30:41 +0000328- Bug #1295808: expat symbols should be namespaced in pyexpat
329
330- Patch #1462338: Upgrade pyexpat to expat 2.0.0
331
Brett Cannon6ee7d012006-06-08 16:23:04 +0000332- Change binascii.hexlify to accept a read-only buffer instead of only a char
333 buffer and actually follow its documentation.
334
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000335- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
336
Nick Coghlanc649ec52006-05-29 12:43:05 +0000337- Patch #1478788 (modified version): The functional extension module has
338 been renamed to _functools and a functools Python wrapper module added.
339 This provides a home for additional function related utilities that are
340 not specifically about functional programming. See PEP 309.
341
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000342- Patch #1493701: performance enhancements for struct module.
343
Georg Brandl378d5922006-05-17 14:26:50 +0000344- Patch #1490224: time.altzone is now set correctly on Cygwin.
345
Georg Brandl8d3342b2006-05-16 07:38:27 +0000346- Patch #1435422: zlib's compress and decompress objects now have a
347 copy() method.
348
Andrew MacIntyre92913322006-06-13 15:04:24 +0000349- Patch #1454481: thread stack size is now tunable at runtime for thread
350 enabled builds on Windows and systems with Posix threads support.
351
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000352- On Win32, os.listdir now supports arbitrarily-long Unicode path names
353 (up to the system limit of 32K characters).
354
355- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
356 As a result, these functions now raise WindowsError instead of OSError.
357
Tim Peters7a822da2006-05-25 21:50:17 +0000358- ``time.clock()`` on Win64 should use the high-performance Windows
359 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
360 Windows platforms).
361
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000362- Calling Tk_Init twice is refused if the first call failed as that
363 may deadlock.
364
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000365- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
366 accept it without potentially using an uninitialized pointer.
367
368- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
369 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
370 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000371
Gregory P. Smith372b5832006-06-05 18:48:21 +0000372- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000373 [pybsddb project SF patch number 1466734]
374
Gregory P. Smith372b5832006-06-05 18:48:21 +0000375- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
376 parameter is supplied. [SF pybsddb bug #1477863]
377
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000378- bsddb: the __len__ method of a DB object has been fixed to return correct
379 results. It could previously incorrectly return 0 in some cases.
380 Fixes SF bug 1493322 (pybsddb bug 1184012).
381
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000382- bsddb: the bsddb.dbtables Modify method now raises the proper error and
383 aborts the db transaction safely when a modifier callback fails.
384 Fixes SF python patch/bug #1408584.
385
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000386- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000387 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000388 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
389 database calls that would previously deadlock. [SF python bug #775414]
390
Vinay Sajip28e57612006-07-01 10:45:20 +0000391- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000392
Walter Dörwald4994d952006-06-19 08:07:50 +0000393- Patch #1506645: add Python wrappers for the curses functions
394 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000395

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000399- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
400 functions.
401
Martin v. Löwis3798da02006-06-17 18:44:27 +0000402- Patch #812986: Update turtle output even if not tracing.
403
Vinay Sajip28e57612006-07-01 10:45:20 +0000404- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000405 Tkinter.BaseWidget.
406
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000407- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
408
Martin v. Löwis337487e2006-06-17 09:15:14 +0000409- Patch #763580: Add name and value arguments to Tkinter variable
410 classes.
411
Georg Brandl83cc0d02006-06-14 08:50:03 +0000412- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
413 mime.types file for determining MIME types.
414
Georg Brandl2605ca82006-06-14 06:08:31 +0000415- Bug #1339007: Shelf objects now don't raise an exception in their
416 __del__ method when initialization failed.
417
Martin v. Löwisd8251432006-06-14 05:21:04 +0000418- Patch #1455898: The MBCS codec now supports the incremental mode for
419 double-byte encodings.
420
Tim Peters43898b42006-06-14 04:09:25 +0000421- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
422 guarantee that adjacent triples in the return list always describe
423 non-adjacent blocks. Previously, a pair of matching blocks could end
424 up being described by multiple adjacent triples that formed a partition
425 of the matching pair.
426
Greg Ward0e0c9f42006-06-11 16:24:11 +0000427- Bug #1498146: fix optparse to handle Unicode strings in option help,
428 description, and epilog.
429
Greg Wardd1c797e2006-06-11 14:42:41 +0000430- Bug #1366250: minor optparse documentation error.
431
Greg Ward7f547402006-06-11 00:40:49 +0000432- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
433 clarify docs.
434
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000435- The wsgiref package has been added to the standard library.
436
Nick Coghlan676725d2006-06-08 13:54:49 +0000437- The functions update_wrapper() and wraps() have been added to the functools
438 module. These make it easier to copy relevant metadata from the original
439 function when writing wrapper functions.
440
Tim Petersd6a9eef2006-06-05 01:48:21 +0000441- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
442 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000443
Martin v. Löwis3f767792006-06-04 19:36:28 +0000444- Patch #1359618: Speed up charmap encoder by using a trie structure
445 for lookup.
446
Tim Petersd609b1a2006-06-02 23:22:51 +0000447- The functions in the ``pprint`` module now sort dictionaries by key
448 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
449 if and only if its display required more than one line, although that
450 wasn't documented. The new behavior increases predictability; e.g.,
451 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
452
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000453- Patch #1497027: try HTTP digest auth before basic auth in urllib2
454 (thanks for J. J. Lee).
455
Georg Brandl2b330372006-05-28 20:23:12 +0000456- Patch #1496206: improve urllib2 handling of passwords with respect to
457 default HTTP and HTTPS ports.
458
George Yoshidaf3c65de2006-05-28 16:39:09 +0000459- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
460
Bob Ippolito7298f272006-05-23 18:43:47 +0000461- Patch #1281707: speed up gzip.readline.
462
Georg Brandlb89316f2006-05-17 15:51:16 +0000463- Patch #1180296: Two new functions were added to the locale module:
464 format_string() to get the effect of "format % items" but locale-aware,
465 and currency() to format a monetary number with currency sign.
466
Georg Brandle3a25832006-05-17 14:56:04 +0000467- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
468 and several features added, such as speed and geometry control.
469
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000470- Patch #1488881: add support for external file objects in bz2 compressed
471 tarfiles.
472
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000473- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
474 stdout arguments, making it possible to redirect input and output
475 for remote debugging.
476
477- Patch #1484695: Update the tarfile module to version 0.8. This fixes
478 a couple of issues, notably handling of long file names using the
479 GNU LONGNAME extension.
480
481- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
482 new flag when ``name`` is already the name of an option flag.
483
484- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
485 package.
486
487- Patch #1472854: make the rlcompleter.Completer class usable on non-
488 UNIX platforms.
489
490- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
491
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000492- Bug #1472827: correctly escape newlines and tabs in attribute values in
493 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000523What's New in Python 2.5 alpha 2?
524=================================
525
526*Release date: 27-APR-2006*
527
528Core and builtins
529-----------------
530
Thomas Heller1b046642006-04-18 18:51:06 +0000531- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
532 by converting these apis from macros into exported functions again:
533
534 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
535 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
536 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
537 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
538 PyRun_String Py_CompileString
539
Martin v. Löwis45294a92006-04-18 06:24:08 +0000540- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
541
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000542- All uses of PyStructSequence_InitType have been changed to initialize
543 the type objects only once, even if the interpreter is initialized
544 multiple times.
545
Neal Norwitz61546162006-04-14 05:20:28 +0000546- Bug #1454485, array.array('u') could crash the interpreter. This was
547 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
548 to unicode when it didn't make sense. 'u#' now requires a unicode string.
549
550- Py_UNICODE is unsigned. It was always documented as unsigned, but
551 due to a bug had a signed value in previous versions.
552
Tim Peters3a5e8b12006-04-11 01:44:07 +0000553- Patch #837242: ``id()`` of any Python object always gives a positive
554 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
555 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000556 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000557 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000558
Tim Peters3a5e8b12006-04-11 01:44:07 +0000559 def __hash__(self):
560 return id(self) # WRONG
561
562 because a hash result must be a (short) Python int but it was always
563 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000564 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000565 was always usable as a hash value before this patch. That's no longer
566 necessarily so.
567
568- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000569 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000570 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000571 #1454844)
572
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000573- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
574 involving generators that have paused outside of any ``try`` or ``with``
575 blocks. (In 2.5a1, a paused generator that was part of a reference
576 cycle could not be garbage collected, regardless of whether it was
577 paused in a ``try`` or ``with`` block.)

586 fails with an error condition.
587
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000588- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
589
590- Bug #1117761: bsddb.*open() no longer raises an exception when using
591 the cachesize parameter.
592
593- Bug #1149413: bsddb.*open() no longer raises an exception when using
594 a temporary db (file=None) with the 'n' flag to truncate on open.
595
596- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
597 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000598
Armin Rigoa9017c32006-04-19 11:50:27 +0000599- Patch #1062014: AF_UNIX sockets under Linux have a special
600 abstract namespace that is now fully supported.
601
Anthony Baxter51bcb682006-04-05 14:51:42 +0000602Library
603-------
604
Peter Astrand7d1d4362006-07-14 14:04:45 +0000605- Bug #1223937: subprocess.CalledProcessError reports the exit status
606 of the process using the returncode attribute, instead of
607 abusing errno.
608
Tim Peters711bf302006-04-25 03:31:36 +0000609- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
610 a doctest to be skipped (the code is not run, and the expected output
611 or exception is ignored).
612
Nick Coghlanda2268f2006-04-24 04:37:15 +0000613- Fixed contextlib.nested to cope with exceptions being raised and
614 caught inside exit handlers.
615
Greg Wardab05edc2006-04-23 03:47:58 +0000616- Updated optparse module to Optik 1.5.1 (allow numeric constants in
617 hex, octal, or binary; add ``append_const`` action; keep going if
618 gettext cannot be imported; added ``OptionParser.destroy()`` method;
619 added ``epilog`` for better help generation).
620
Tim Peters21fbd572006-04-21 21:18:10 +0000621- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
622 called from a thread spawned as a side effect of importing a module.
623
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000624- The pydoc module now supports documenting packages contained in
625 .zip or .egg files.
626
627- The pkgutil module now has several new utility functions, such
628 as ``walk_packages()`` to support working with packages that are either
629 in the filesystem or zip files.
630
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000631- The mailbox module can now modify and delete messages from

663-----
664
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000665- The Makefile now has a reindent target, which runs reindent.py on
666 the library.
667
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000668- Patch #1470875: Building Python with MS Free Compiler
669
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000670- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000671
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000672- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
673 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000674 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000675 CXX from --with-cxx-main, see description in README.
676

678
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000679- Fixed a libffi build problem on MIPS systems.
680
Tim Peters8931ff12006-05-13 23:28:20 +0000681- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
682 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
683 and "%zu" for unsigned integers of type ``size_t``.
684
Anthony Baxter51bcb682006-04-05 14:51:42 +0000685Tests
686-----
687
Nick Coghlanda2268f2006-04-24 04:37:15 +0000688- test_contextlib now checks contextlib.nested can cope with exceptions
689 being raised and caught inside exit handlers.
690
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000691- test_cmd_line now checks operation of the -m and -c command switches
692
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000693- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
694 it separately and by hand. It also wasn't cleaning up its changes to
695 the current Decimal context.
696
Thomas Woutersabd08882006-04-26 15:53:30 +0000697- regrtest.py now has a -M option to run tests that test the new limits of
698 containers, on 64-bit architectures. Running these tests is only sensible
699 on 64-bit machines with more than two gigabytes of memory. The argument
700 passed is the maximum amount of memory for the tests to use.

709-------------
710
Tim Petersb06d28c2006-05-12 01:57:59 +0000711- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
712
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000713- PEP 343: Added Context Types section to the library reference
714 and attempted to bring other PEP 343 related documentation into
715 line with the implementation and/or python-dev discussions.
716
Tim Peters8dc73d22006-04-24 02:03:16 +0000717- Bug #1337990: clarified that ``doctest`` does not support examples
718 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000721What's New in Python 2.5 alpha 1?
722=================================
723
Anthony Baxterebed3f62006-04-03 15:03:44 +0000724*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000725
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000726Core and builtins
727-----------------
728
Nick Coghlan43832302006-04-23 17:04:07 +0000729- PEP 338: -m command line switch now delegates to runpy.run_module
730 allowing it to support modules in packages and zipfiles
731
Martin v. Löwisc661b882006-04-20 04:54:23 +0000732- On Windows, .DLL is not an accepted file name extension for
733 extension modules anymore; extensions are only found if they
734 end in .PYD.
735
Martin v. Löwisea62d252006-04-03 10:56:49 +0000736- Bug #1421664: sys.stderr.encoding is now set to the same value as
737 sys.stdout.encoding.
738
Neal Norwitz92e212f2006-04-03 04:48:37 +0000739- __import__ accepts keyword arguments.
740
Georg Brandlccadf842006-03-31 18:54:53 +0000741- Patch #1460496: round() now accepts keyword arguments.
742
Anthony Baxter262c00a2006-03-30 10:53:17 +0000743- Fixed bug #1459029 - unicode reprs were double-escaped.
744
Hye-Shik Changd478f342006-03-23 12:32:36 +0000745- Patch #1396919: The system scope threads are reenabled on FreeBSD
746 5.4 and later versions.
747
Neal Norwitze98ccf62006-03-23 05:39:47 +0000748- Bug #1115379: Compiling a Unicode string with an encoding declaration
749 now gives a SyntaxError.
750
Georg Brandlabd1ff82006-03-18 07:59:59 +0000751- Previously, Python code had no easy way to access the contents of a
752 cell object. Now, a ``cell_contents`` attribute has been added
753 (closes patch #1170323).
754
Tim Peterscf79aac2006-03-16 01:14:46 +0000755- Patch #1123430: Python's small-object allocator now returns an arena to
756 the system ``free()`` when all memory within an arena becomes unused
757 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
758 freed. Some applications will see a drop in virtual memory size now,
759 especially long-running applications that, from time to time, temporarily
760 use a large number of small objects. Note that when Python returns an
761 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000762 platform C library will in turn return that memory to the operating system.
763 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000764 appears to be effective at least on Microsoft C and gcc-based systems.
765 Thanks to Evan Jones for hard work and patience.
766
Georg Brandl533ff6f2006-03-08 18:09:27 +0000767- Patch #1434038: property() now uses the getter's docstring if there is
768 no "doc" argument given. This makes it possible to legitimately use
769 property() as a decorator to produce a read-only property.
770
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000771- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
772 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
773 of requiring an int or long in slicing and a few other contexts, enabling
774 other objects (e.g. Numeric Python's integers) to be used as slice indices.
775
Neal Norwitz995acdf2006-03-07 05:01:00 +0000776- Fixed various bugs reported by Coverity's Prevent tool.
777
Brett Cannonbf364092006-03-01 04:25:17 +0000778- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
779 new exception base class, BaseException, which has a new message attribute.
780 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
781 Raising a string exception now raises a DeprecationWarning.
782
Thomas Woutersfb609f42006-02-28 16:37:25 +0000783- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
784 explicitly relative, using 'from .module import name' to mean 'from the same
785 package as this module is in. Imports without dots still default to the
786 old relative-then-absolute, unless 'from __future__ import
787 absolute_import' is used.
788
Brett Cannona7446e32006-02-27 23:39:10 +0000789- Properly check if 'warnings' raises an exception (usually when a filter set
790 to "error" is triggered) when raising a warning for raising string
791 exceptions.
792
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000793- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000794 The name was removed from Include/code.h.
795
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000796- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000797
Guido van Rossum1968ad32006-02-25 22:38:04 +0000798- Patch 1433928:
799 - The copy module now "copies" function objects (as atomic objects).
800 - dict.__getitem__ now looks for a __missing__ hook before raising
801 KeyError.
802
Tim Peters84ef21c2006-02-28 20:39:06 +0000803- PEP 343: with statement implemented. Needs ``from __future__ import
804 with_statement``. Use of 'with' as a variable will generate a warning.
805 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000806 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000807 The following objects have __context__ methods:
808 - The built-in file type.
809 - The thread.LockType type.
810 - The following types defined by the threading module:
811 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
812 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000813
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000814- Fix the encodings package codec search function to only search
815 inside its own package. Fixes problem reported in patch #1433198.
816
817 Note: Codec packages should implement and register their own
818 codec search function. PEP 100 has the details.
819
Tim Peters9ea89d22006-06-04 03:26:02 +0000820- PEP 353: Using ``Py_ssize_t`` as the index type.
821
822- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
823 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
824 now allow Python to make use of memory blocks exceeding 2**32 bytes for
825 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
826 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000827
Neal Norwitzfc76d632006-01-10 06:03:13 +0000828- Patch #1400181, fix unicode string formatting to not use the locale.
829 This is how string objects work. u'%f' could use , instead of .
830 for the decimal point. Now both strings and unicode always use periods.
831
Neal Norwitz671b9e32006-01-09 07:07:12 +0000832- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
833 configure would break checking curses.h.
834
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000835- Bug #959576: The pwd module is now builtin. This allows Python to be
836 built on UNIX platforms without $HOME set.
837
Neal Norwitzc10978f2005-12-19 06:07:16 +0000838- Bug #1072182, fix some potential problems if characters are signed.
839
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000840- Bug #889500, fix line number on SyntaxWarning for global declarations.
841
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000842- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
843
Neal Norwitze7214a12005-12-18 05:03:17 +0000844- Support for converting hex strings to floats no longer works.
845 This was not portable. float('0x3') now raises a ValueError.
846
Barry Warsaw2a38a862005-12-18 01:27:35 +0000847- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000848 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000849 is now displayed in interactive prompt banner.
850
Georg Brandlfa166682005-12-17 21:45:17 +0000851- Implementation of PEP 341 - Unification of try/except and try/finally.
852 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000853 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000854
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000855- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
856 now encodes backslash correctly.
857
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000858- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
859
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000860- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000861 and long longs.
862
Neal Norwitz67715f02005-11-09 06:59:35 +0000863- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000864 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000865 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000866
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000867- Replaced most Unicode charmap codecs with new ones using the
868 new Unicode translate string feature in the builtin charmap
869 codec; the codecs were created from the mapping tables available
870 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
871 encodings now include a mapping for the Apple logo)
872
Tim Peterse3547fd2005-12-16 23:13:57 +0000873- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000874
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000875- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000876
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000877- A new AST parser implementation was completed. The abstract
878 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000879 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000880
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000881- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000882 The following code now raises a SyntaxError: foo(a = i for i in range(10))
883
Neal Norwitz708e51a2005-10-03 04:48:15 +0000884- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
885
Neal Norwitz11bd1192005-10-03 00:54:56 +0000886- SF Bug #887946: fix segfault when redirecting stdin from a directory.
887 Provide a warning when a directory is passed on the command line.
888
Neal Norwitz40d37812005-10-02 01:48:49 +0000889- Fix segfault with invalid coding.
890
891- SF bug #772896: unknown encoding results in MemoryError.
892
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000893- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000894 supported a __len__() method which evaluated to False when the iterator
895 was empty.
896
Guido van Rossum630db602005-09-20 18:49:54 +0000897- On 64-bit platforms, when __len__() returns a value that cannot be
898 represented as a C int, raise OverflowError.
899
Skip Montanarof8948ca2005-09-19 03:54:46 +0000900- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000901 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000902
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000903- SF bug #893549: parsing keyword arguments was broken with a few format
904 codes.
905
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000906- Changes donated by Elemental Security to make it work on AIX 5.3
907 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
908 bug #105470: test_pwd fails on 64bit system (Opteron).
909
Guido van Rossum539c6622005-09-14 17:49:54 +0000910- Changes donated by Elemental Security to make it work on HP-UX 11 on
911 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
912
Georg Brandl4550b8d2005-08-26 06:43:52 +0000913- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000914 (fixes bug #1119418).
915
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000916- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
917
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000918- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
919 exceptions that cause a function to exit.
920
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000921- The implementation of set() and frozenset() was revised to use its
922 own internal data structure. Memory consumption is reduced by 1/3
923 and there are modest speed-ups as well. The API is unchanged.
924
Tim Petersde7990b2005-07-17 23:45:23 +0000925- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
926
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000927- SF bug #1229429: PyObject_CallMethod failed to decrement some
928 reference counts in some error exit cases.
929
Tim Petersecc6e6a2005-07-10 22:30:55 +0000930- SF bug #1185883: Python's small-object memory allocator took over
931 a block managed by the platform C library whenever a realloc specified
932 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000933 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000934 portable way to copy data from the C-managed block into Python's
935 small-object space without risking a memory fault. Python's small-object
936 realloc now leaves such blocks under the control of the platform C
937 realloc.
938
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000939- SF bug #1232517: An overflow error was not detected properly when
940 attempting to convert a large float to an int in os.utime().
941
Raymond Hettinger3296e692005-06-29 23:29:56 +0000942- SF bug #1224347: hex longs now print with lowercase letters just
943 like their int counterparts.
944
Michael W. Hudson188d4362005-06-20 16:52:57 +0000945- SF bug #1163563: the original fix for bug #1010677 ("thread Module
946 Breaks PyGILState_Ensure()") broke badly in the case of multiple
947 interpreter states; back out that fix and do a better job (see
948 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
949 for a longer write-up of the problem).
950
Michael W. Hudsondf888462005-06-03 14:41:55 +0000951- SF patch #1180995: marshal now uses a binary format by default when
952 serializing floats.
953
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000954- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
955 the routines that promise to produce IEEE 754 binary representations
956 of floats now simply copy bytes around.
957
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000958- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
959 278.
960
Brett Cannonc3647ac2005-04-26 03:45:26 +0000961- patch #1109424: int, long, float, complex, and unicode now check for the
962 proper magic slot for type conversions when subclassed. Previously the
963 magic slot was ignored during conversion. Semantics now match the way
964 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000965 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000966 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000967 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000968
Barry Warsawc8d907c2005-04-19 23:43:40 +0000969- Descriptors defined in C with a PyGetSetDef structure, where the setter is
970 NULL, now raise an AttributeError when attempting to set or delete the
971 attribute. Previously a TypeError was raised, but this was inconsistent
972 with the equivalent pure-Python implementation.
973
Michael W. Hudson774479c2005-04-18 08:46:17 +0000974- It is now safe to call PyGILState_Release() before
975 PyEval_InitThreads() (note that if there is reason to believe there
976 are multiple threads around you still must call PyEval_InitThreads()
977 before using the Python API; this fix is for extension modules that
978 have no way of knowing if Python is multi-threaded yet).
979
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000980- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
981 disabled caused a crash.
982
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000983- Bug #1165306: instancemethod_new allowed the creation of a method
984 with im_class == im_self == NULL, which caused a crash when called.
985
Tim Petersecc6e6a2005-07-10 22:30:55 +0000986- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000987 fixes the crash seen in bug #1165761
988
Raymond Hettinger96229b12005-03-11 06:49:40 +0000989- Added two new builtins, any() and all().
990
Brett Cannon409d8f22005-03-05 06:47:57 +0000991- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000992 (e.g., ``class C(): pass`` is no longer a syntax error).
993 Patch #1176012 added support to the 'parser' module and 'compiler' package
994 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000995
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000996- Patch #1115086: Support PY_LONGLONG in structmember.
997
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000998- Bug #1155938: new style classes did not check that __init__() was
999 returning None.
1000
Tim Petersecc6e6a2005-07-10 22:30:55 +00001001- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001002 ('\') with a specific error message.
1003
Martin v. Löwisff232d72005-03-03 09:24:38 +00001004- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1005
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001006- Bug #1124295: the __name__ attribute of file objects was
1007 inadvertently made inaccessible in restricted mode.
1008
Tim Petersecc6e6a2005-07-10 22:30:55 +00001009- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001010 an ferror() call.
1011
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001012- min() and max() now support key= arguments with the same meaning as in
1013 list.sort().
1014
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001015- The peephole optimizer now performs simple constant folding in expressions:
1016 (2+3) --> (5).
1017
Raymond Hettingera422c342005-01-11 03:03:27 +00001018- set and frozenset objects can now be marshalled. SF #1098985.
1019
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001020- Bug #1077106: Poor argument checking could cause memory corruption
1021 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001022
Jeremy Hyltonab630502005-02-04 18:44:06 +00001023- The parser did not complain about future statements in illegal
1024 positions. It once again reports a syntax error if a future
1025 statement occurs after anything other than a doc string.
1026
Neil Schemenauercf52c072005-08-12 17:34:58 +00001027- Change the %s format specifier for str objects so that it returns a
1028 unicode instance if the argument is not an instance of basestring and
1029 calling __str__ on the argument returns a unicode instance.
1030
Tim Petersf4e69282006-02-27 17:15:31 +00001031- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1032 current thread state when the auto-GIL-state machinery knows about
1033 it (since the thread state is being deleted, continuing to remember it
1034 can't help, but can hurt if another thread happens to get created with
1035 the same thread id).
1036
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001037Extension Modules
1038-----------------
1039

1054
1055- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1056
1057- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001058 is deprecated. The undocumented re.engine variable no longer exists.
1059

1062
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001063- The unicodedata module was updated to the 4.1 version of the Unicode
1064 database. The 3.2 version is still available as unicodedata.db_3_2_0
1065 for applications that require this specific version (such as IDNA).
1066
Neal Norwitzb62c4332006-03-04 18:35:47 +00001067- The timing module is no longer built by default. It was deprecated
1068 in PEP 4 in Python 2.0 or earlier.
1069
Guido van Rossum1968ad32006-02-25 22:38:04 +00001070- Patch 1433928: Added a new type, defaultdict, to the collections module.
1071 This uses the new __missing__ hook behavior added to dict (see above).
1072
Georg Brandldbd83392006-02-20 09:42:33 +00001073- Bug #854823: socketmodule now builds on Sun platforms even when

1083 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1084 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1085
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001086- Patch #1422385: The nis module now supports access to domains other
1087 than the system default domain.
1088
Martin v. Löwis14694662006-02-03 12:54:16 +00001089- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1090 are reported, the limit on path name lengths is removed, and stat reports
1091 WindowsError now (instead of OSError).
1092
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001093- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001227- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1228 been renamed to have only a single underscore prefix. This was done to
1229 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001230
Nick Coghlan43832302006-04-23 17:04:07 +00001231- PEP 338: new module runpy defines a run_module function to support
1232 executing modules which provide access to source code or a code object
1233 via the PEP 302 import mechanisms.
1234
Anthony Baxter93f5b932006-04-03 08:05:07 +00001235- The email module's parsedate_tz function now sets the daylight savings
1236 flag to -1 (unknown) since it can't tell from the date whether it should

1243 in attribute values.
1244
Anthony Baxterc51ee692006-04-01 00:57:31 +00001245- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001246 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001247 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001248 module will not be built.
1249
Tim Petersc17976e2006-04-01 00:26:53 +00001250- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1251 aren't officially supported here, and trying to use them will probably
1252 raise an exception some day. But dicts have been allowed, and "mostly
1253 worked", so support for them won't go away without warning.
1254
Georg Brandl338ef7d2006-03-31 18:42:16 +00001255- Bug #1445068: getpass.getpass() can now be given an explicit stream
1256 argument to specify where to write the prompt.
1257
Georg Brandl22ec80b2006-03-31 18:25:44 +00001258- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1267 to make it easier to monitor when daemon threads have completed
1268 processing all enqueued tasks. Patch #1455676.
1269
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001270- popen2.Popen objects now preserve the command in a .cmd attribute.

1273
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001274- email 4.0 package now integrated. This is largely the same as the email 3.0
1275 package that was included in Python 2.3, except that PEP 8 module names are
1276 now used (e.g. mail.message instead of email.Message). The MIME classes
1277 have been moved to a subpackage (e.g. email.mime.text instead of
1278 email.MIMEText). The old names are still supported for now. Several
1279 deprecated Message methods have been removed and lots of bugs have been
1280 fixed. More details can be found in the email package documentation.
1281
Walter Dörwald40108c92006-03-27 08:15:44 +00001282- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1283 (a subclass of tuple) that provides incremental decoders and encoders
1284 (a way to use stateful codecs without the stream API). Python functions
1285 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1286 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1287 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001288
Walter Dörwald067db482006-03-15 22:17:27 +00001289- Patch #1359365: Calling next() on a closed StringIO.String object raises
1290 a ValueError instead of a StopIteration now (like file and cString.String do).
1291 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1292 called before (like file and StringIO.StringIO do).

1306 and helpful context managers nested() and closing().
1307

Tim Peterse3547fd2005-12-16 23:13:57 +00001366 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1367 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1368 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1369 Ronald L. Rivest offered this advice for Python:
1370
1371 "The consensus of researchers in this area (at least as
1372 expressed at the NIST Hash Function Workshop 10/31/05),
1373 is that SHA-256 is a good choice for the time being, but
1374 that research should continue, and other alternatives may
1375 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001376
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001377- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandla4a8b822005-07-15 09:13:21 +00001447- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1448 parameter, but uses the usual "kwargs=None".
1449
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001450- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001451 Patch #1209527 (Contributed by Connelly).
1452
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001453- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1454 to W3C name (404 -> 'Not Found'). RFE #1216944.
1455
Georg Brandl9e43acf2005-07-04 17:16:07 +00001456- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1457 as this can cause problems with apps closing all file descriptors.
1458
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001459- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001460 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001461
Georg Brandl2f210b62005-06-26 22:09:06 +00001462- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
1463
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001464- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1465 error messages.
1466
Georg Brandl379f99d2005-06-26 21:09:38 +00001467- Bug #1108948: Cookie.py produced invalid JavaScript code.
1468
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001469- The tokenize module now detects and reports indentation errors.
1470 Bug #1224621.
1471
Raymond Hettinger68c04532005-06-10 11:05:19 +00001472- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001473 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001474 the generate_tokens() function now accepts a callable argument that
1475 terminates by raising StopIteration.
1476
Georg Brandl9166e1a2005-06-04 09:20:03 +00001477- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1478
Georg Brandl268e61c2005-06-03 14:28:50 +00001479- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1480 component of the path.
1481
Skip Montanaro174dd222005-05-14 20:54:16 +00001482- Patch #1120353: The xmlrpclib module provides better, more transparent,
1483 support for datetime.{datetime,date,time} objects. With use_datetime set
1484 to True, applications shouldn't have to fiddle with the DateTime wrapper
1485 class at all.
1486
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001487- distutils.commands.upload was added to support uploading distribution
1488 files to PyPI.
1489
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001490- distutils.commands.register now encodes the data as UTF-8 before posting
1491 them to PyPI.
1492
Raymond Hettinger267b8682005-03-27 10:47:39 +00001493- decimal operator and comparison methods now return NotImplemented
1494 instead of raising a TypeError when interacting with other types. This
1495 allows other classes to implement __radd__ style methods and have them
1496 work as expected.
1497
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001498- Bug #1163325: Decimal infinities failed to hash. Attempting to
1499 hash a NaN raised an InvalidOperation instead of a TypeError.
1500
Tim Petersecc6e6a2005-07-10 22:30:55 +00001501- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001502 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1503
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001504- Patch #1043890: Add extractall method to tarfile.

Raymond Hettingerbab41432005-02-05 01:31:19 +00001534- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1535
Guido van Rossumd0641422005-02-03 15:01:24 +00001536- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1537 disables recursive traversal through instance attributes, which can
1538 be exploited in various ways.
1539
Tim Peterse3547fd2005-12-16 23:13:57 +00001540- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001541 flags on the HTTP listening socket.
1542
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001543- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1544 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1545
Tim Peterse3547fd2005-12-16 23:13:57 +00001546- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001547 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1548
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001549- Bug #1110478: Revert os.environ.update to do putenv again.
1550
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001551- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1552
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001553- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1554
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001555- Enhancements to the csv module:
1556
1557 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001558 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001559 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001560 + Dialect parameter parsing has been re-implemented to improve error
1561 reporting.
1562 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1563 dictates.
1564 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001565 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001566 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001567 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1568 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001569 + reader now allows \r characters to be quoted (previously it only allowed
1570 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001571 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001572 + Dialect classes passed to the module are no longer instantiated by
1573 the module before being parsed (the former validation scheme required
1574 this, but the mechanism was unreliable).
1575 + The dialect registry now contains instances of the internal
1576 C-coded dialect type, rather than references to python objects.
1577 + the internal c-coded dialect type is now immutable.
1578 + register_dialect now accepts the same keyword dialect specifications
1579 as the reader and writer, allowing the user to register dialects
1580 without first creating a dialect class.
1581 + a configurable limit to the size of parsed fields has been added -
1582 previously, an unmatched quote character could result in the entire
1583 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001584 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001585 the parser field size limit (returning the former limit). The initial
1586 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001587 + A line_num attribute has been added to the reader object, which tracks
1588 the number of lines read from the source iterator. This is not
1589 the same as the number of records returned, as records can span
1590 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001591 + reader and writer objects were not being registered with the cyclic-GC.
1592 This has been fixed.
1593
Brett Cannone6539c42005-01-08 02:43:53 +00001594- _DummyThread objects in the threading module now delete self.__block that is
1595 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1596 lock primitives tend to be limited in number and thus should not be wasted on
1597 a _DummyThread object. Fixes bug #1089632.
1598
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001599- The imghdr module now detects Exif files.
1600
Raymond Hettinger6065d322004-12-20 23:51:53 +00001601- StringIO.truncate() now correctly adjusts the size attribute.
1602 (Bug #951915).
1603
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001604- locale.py now uses an updated locale alias table (built using
1605 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1606 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001607 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001608
Raymond Hettinger3557f422004-12-07 12:02:02 +00001609- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1610
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001611- the pickle module no longer accepts the deprecated None option in the
1612 args tuple returned by __reduce__().
1613
Brett Cannon84667c02004-12-07 03:25:18 +00001614- optparse now optionally imports gettext. This allows its use in setup.py.
1615
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001616- the pickle module no longer uses the deprecated bin parameter.
1617
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001618- the shelve module no longer uses the deprecated binary parameter.
1619
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001620- the pstats module no longer uses the deprecated ignore() method.
1621
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001622- the filecmp module no longer uses the deprecated use_statcache argument.
1623
Raymond Hettinger664347b2004-12-04 21:21:53 +00001624- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1625 extended or overridden by subclasses. Formerly, the subclassed method would
1626 be ignored by the rest of the module. (Bug #1078905).
1627
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001628- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001629 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001630
Walter Dörwald36733692004-12-22 12:50:50 +00001631- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1632 once when a size argument is given. This prevents a buffer overflow in the
1633 tokenizer with very long source lines.
1634
Barry Warsaw538561e2006-01-01 21:48:54 +00001635- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1636 immediately after creating the object, without any intervening
1637 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001638
Skip Montanaro05885812005-01-16 20:48:27 +00001639- The reconvert.quote function can now emit triple-quoted strings. The
1640 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001641
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001642- ``UserString.MutableString`` now supports negative indices in
1643 ``__setitem__`` and ``__delitem__``
1644
Greg Ward40407942005-03-05 02:53:17 +00001645- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1646 correctly.
1647
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001648- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1649 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1650 character even if the user has passed a size parameter to get a proper
1651 line ending. Remove the special handling of a "\r\n" that has been split
1652 between two lines.
1653
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001654- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1655 about illegal code points. The codec now supports PEP 293 style error
1656 handlers.
1657
Walter Dörwald78a78b02005-09-01 12:04:29 +00001658- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001659 from the input stream, so that the output is a byte string in the correct
1660 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001661
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001662- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1663 considering it exactly like a '*'.
1664
Walter Dörwald007f8df2005-10-09 19:42:27 +00001665- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1666 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001667
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001668- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1669
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001670- Patch #1413711: Certain patterns of differences were making difflib
1671 touch the recursion limit.
1672
Walter Dörwald58917a62006-03-31 15:26:22 +00001673- Bug #947906: An object oriented interface has been added to the calendar
1674 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001675 called as a script (e.g. via ``python -mcalendar``). Localized month and
1676 weekday names can be ouput (even if an exotic encoding is used) using
1677 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001678

1697
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001698- Bug #1189330: configure did not correctly determine the necessary
1699 value of LINKCC if python was built with GCC 4.0.
1700
Trent Mick8321b422005-07-26 02:29:21 +00001701- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1702 vulnerability in zlib 1.2.1 and 1.2.2.
1703
Brett Cannon08cd5982005-04-24 22:26:38 +00001704- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1705 flags that change binary compatibility. Changes were also made to
1706 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001707 compilation of the interpreter and of C extensions through distutils.

Bob Ippolitoed233462005-03-29 13:47:59 +00001709- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1710 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1711 no longer exists). This configure patch makes things right.
1712
Martin v. Löwise2713be2005-03-08 15:03:08 +00001713- Bug #1158607: Build with --disable-unicode again.
1714
Brett Cannon46d96232005-02-16 00:07:19 +00001715- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1716 defined. Discovered as a result of not being able to build on OS X.
1717
Brett Cannon516592f2004-12-07 00:42:59 +00001718- setup.py now uses the directories specified in LDFLAGS using the -L option
1719 and in CPPFLAGS using the -I option for adding library and include
1720 directories, respectively, for compiling extension modules against. This has
1721 led to the core being compiled using the values in CPPFLAGS. It also removes
1722 the need for the special-casing of both DarwinPorts and Fink for darwin since
1723 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1724 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1725 Fink, ``-I/opt/local/include`` for DarwinPorts).
1726
Brett Cannon43802422005-02-10 20:48:03 +00001727- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1728 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1729 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1730 Closes bug #1096244. Thanks Gregory Bond.

1733-----
1734
Tim Petersc9d78aa2006-03-26 23:27:58 +00001735- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1736 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1737 is obtained via the ``PyObject_`` family, it must be released via the
1738 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1739 always been officially true, but when Python's small-object allocator was
1740 introduced, an attempt was made to cater to a few extension modules
1741 discovered at the time that obtained memory via ``PyObject_New`` but
1742 released it via ``PyMem_DEL``. It's years later, and if such code still
1743 exists it will fail now (probably with segfaults, but calling wrong
1744 low-level memory management functions can yield many symptoms).
1745
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001746- Added a C API for set and frozenset objects.
1747

1749
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001750- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1751 mapping argument now. This string is used as a mapping table. Byte values
1752 greater than the length of the string and 0xFFFE are treated as undefined
1753 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001761- Patch #1276356: New resource "urlfetch" is implemented. This enables
1762 even impatient people to run tests that require remote files.
