Fred Drake53912162006-07-29 13:22:49 +00007What's New in Python 2.5 beta 3?
8================================
Neal Norwitza1f10902006-07-12 07:28:29 +00009
10*Release date: XX-AUG-2006*
11
12Core and builtins
13-----------------
14
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000015- Bug #1515471: string.replace() accepts character buffers again.
16
Neal Norwitz07aadb12006-07-30 06:55:48 +000017- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
18 This provides the proper warning for struct.pack().
19 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
20
Neal Norwitz0d62a062006-07-30 06:53:31 +000021- Patch #1531113: Fix augmented assignment with yield expressions.
22 Also fix a SystemError when trying to assign to yield expressions.
23
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000024- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
25 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
26 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
27 excessive filesystem operations during imports.
28
Tim Petersbc24eee2006-07-27 01:14:53 +000029- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
30 operations on signed longs that are formally undefined by C.
31 Unfortunately, at least one compiler now cares about that, so complicated
32 the code to make that compiler happy again.
33
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000034- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
35
Martin v. Löwisd22968a2006-07-24 11:54:53 +000036- Patch #1232023: Stop including current directory in search
37 path on Windows.
38
Neal Norwitze1fdb322006-07-21 05:32:28 +000039- Fix some potential crashes found with failmalloc.
40
Neal Norwitze7563102006-07-17 01:00:16 +000041- Fix warnings reported by Klocwork's static analysis tool.
42
Neal Norwitz84be93b2006-07-16 01:50:38 +000043- Bug #1512814, Fix incorrect lineno's when code within a function
44 had more than 255 blank lines.
45
Georg Brandl9dceedb2006-07-12 15:31:17 +000046- Patch #1521179: Python now accepts the standard options ``--help`` and
47 ``--version`` as well as ``/?`` on Windows.
48
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000049- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000050 again. Fixing this problem required changing the .pyc magic number.
51 This means that .pyc files generated before 2.5c1 will be regenerated.
52
Tim Peters112aad32006-07-19 00:03:19 +000053- Bug #1524317: Compiling Python ``--without-threads`` failed.
54 The Python core compiles again then, and, in a build without threads, the
55 new ``sys._current_frames()`` returns a dictionary with one entry,
56 mapping the faux "thread id" 0 to the current frame.
57
Ronald Oussoren3075e162006-07-25 20:28:55 +000058- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000059
Ronald Oussoren3075e162006-07-25 20:28:55 +000060
Neal Norwitza1f10902006-07-12 07:28:29 +000061Library
62-------
63
Fred Drakefbdeaad2006-07-29 16:56:15 +000064- Rename of the xml package to xmlcore, and the import hackery done to
65 make it appear at both names, has been removed. Bug #1511497,
66 #1513611, and probably others.
67
Georg Brandledd9b0d2006-07-29 09:33:26 +000068- Bug #1441397: The compiler module now recognizes module and function
69 docstrings correctly as it did in Python 2.4.
70
Tim Peters6f681472006-07-27 23:44:37 +000071- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
72 lost that tests are sorted by name before being run. This rarely
73 matters for well-written tests, but can create baffling symptoms if
74 side effects from one test to the next affect outcomes. ``DocTestFinder``
75 has been changed to sort the list of tests it returns.
76
Martin v. Löwis997ceff2006-07-27 06:38:16 +000077- The distutils version has been changed to 2.5.0.
78
Martin v. Löwis9298eff2006-07-26 12:12:56 +000079- Bug #978833: Really close underlying socket in _socketobject.close.
80
Georg Brandl0619a322006-07-26 07:40:17 +000081- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
82 with title().
83
Georg Brandlcf0c1722006-07-26 07:23:32 +000084- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
85 to recursive calls and call it with the failing package name.
86
Martin v. Löwis0b483032006-07-25 09:53:12 +000087- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
88
Georg Brandlc13c34c2006-07-24 14:09:56 +000089- Patch #1515343: Fix printing of deprecated string exceptions with a
90 value in the traceback module.
91
Greg Ward48fae7a2006-07-23 16:05:51 +000092- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
93
Martin v. Löwis426f4a12006-07-18 17:46:31 +000094- Patch #1524429: Use repr() instead of backticks in Tkinter again.
95
Brett Cannoncaebe222006-07-18 04:41:36 +000096- Bug #1520914: Change time.strftime() to accept a zero for any position in its
97 argument tuple. For arguments where zero is illegal, the value is forced to
98 the minimum value that is correct. This is to support an undocumented but
99 common way people used to fill in inconsequential information in the time
100 tuple pre-2.4.
101
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000102- Patch #1220874: Update the binhex module for Mach-O.
103
Barry Warsawb110bad2006-07-21 14:51:07 +0000104- The email package has improved RFC 2231 support, specifically for
105 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
106 (name*0=<blah>) parameter continuations. This may change the types of
107 values returned from email.message.Message.get_param() and friends.
108 Specifically in some cases where non-encoded continuations were used,
109 get_param() used to return a 3-tuple of (None, None, string) whereas now it
110 will just return the string (since non-encoded continuations don't have
111 charset and language parts).
112
113 Also, whereas % values were decoded in all parameter continuations, they are
114 now only decoded in encoded parameter parts.
115
Ronald Oussoren3075e162006-07-25 20:28:55 +0000116- Bug #1517990: IDLE keybindings on MacOS X now work correctly
117
118- Bug #1517996: IDLE now longer shows the default Tk menu when a
119 path browser, class browser or debugger is the frontmost window on MacOS X
120
Barry Warsaw00decd72006-07-27 23:43:15 +0000121- Patch #1520294: Support for getset and member descriptors in types.py,
122 inspect.py, and pydoc.py. Specifically, this allows for querying the type
123 of an object against these built-in types and more importantly, for getting
124 their docstrings printed in the interactive interpreter's help() function.
125
Ronald Oussoren3075e162006-07-25 20:28:55 +0000126
Neal Norwitza1f10902006-07-12 07:28:29 +0000127Extension Modules
128-----------------
129
Thomas Heller1393d6a2006-07-28 21:43:20 +0000130- Patch #1529514: The _ctypes extension is now compiled on more
131 openbsd target platforms.
132
Tim Peters9cab5932006-07-28 00:30:00 +0000133- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
134 a memory leak, affecting pickles and deep copies.
135
Tim Petersbc24eee2006-07-27 01:14:53 +0000136- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000137 Paul Eggert.
138
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000139- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
140
Thomas Hellerce049a02006-07-14 17:51:14 +0000141- Patch #1521817: Index range checking on ctypes arrays containing
142 exactly one element enabled again. This allows iterating over these
143 arrays, without the need to check the array size before.
144
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000145- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000146 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000147 /dev/null in certain cases; this is now fixed.
148
Thomas Heller47d7a062006-07-12 08:43:47 +0000149- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
150 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000151
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000152- Because of a misspelled preprocessor symbol, ctypes was always
153 compiled without thread support; this is now fixed.
154
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000155- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
156 methods now allow their database parameter to be None as the
157 sleepycat API allows.
158
Matt Flemingec926502006-07-28 11:27:27 +0000159- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
160 bluetooth API compared with Linux and FreeBSD.
161
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000162Tests
163-----
164
165- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
166 how long the test file should take to play. Now accepts taking 2.93 secs
167 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
168
Georg Brandl4793aa32006-07-28 18:31:39 +0000169- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
170 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
171 run via ``regrtest.py``. Now they do.

Georg Brandlad29e632006-06-21 17:45:17 +0000178
179Core and builtins
180-----------------
181
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000182- Bug #1441486: The literal representation of -(sys.maxint - 1)
183 again evaluates to a int object, not a long.
184
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000185- Bug #1501934: The scope of global variables that are locally assigned
186 using augmented assignment is now correctly determined.
187
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000188- Bug #927248: Recursive method-wrapper objects can now safely
189 be released.
190
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000191- Bug #1417699: Reject locale-specific decimal point in float()
192 and atof().
193
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000194- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
195 omit a default "error" argument for NULL pointer. This allows
196 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000197
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000198- Bug #1519018: 'as' is now validated properly in import statements.
199
Neal Norwitz28746ab2006-07-09 22:14:42 +0000200- On 64 bit systems, int literals that use less than 64 bits are
201 now ints rather than longs.
202
Neal Norwitzed657552006-07-10 00:04:44 +0000203- Bug #1512814, Fix incorrect lineno's when code at module scope
204 started after line 256.
205
Tim Peters32a83612006-07-10 21:08:24 +0000206- New function ``sys._current_frames()`` returns a dict mapping thread
207 id to topmost thread stack frame. This is for expert use, and is
208 especially useful for debugging application deadlocks. The functionality
209 was previously available in Fazal Majid's ``threadframe`` extension
210 module, but it wasn't possible to do this in a wholly threadsafe way from
211 an extension.
212
Georg Brandlad29e632006-06-21 17:45:17 +0000213Library
214-------
215
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000216- Patch #1519566: Update turtle demo, make begin_fill idempotent.
217
Tim Peters32a83612006-07-10 21:08:24 +0000218- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000219 environment variable to be set in order to the SDK environment
220 for finding the compiler, include files, etc.
221
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000222- Bug #1515998: Properly generate logical ids for files in bdist_msi.
223
Nick Coghlan2d792252006-07-06 13:47:18 +0000224- warnings.py now ignores ImportWarning by default
225
Thomas Woutersadd19112006-07-05 11:03:49 +0000226- string.Template() now correctly handles tuple-values. Previously,
227 multi-value tuples would raise an exception and single-value tuples would
228 be treated as the value they contain, instead.
229
Martin v. Löwisede77f52006-07-03 13:01:35 +0000230- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
231 even if some data are received.
232
Martin v. Löwis45482392006-07-03 12:28:58 +0000233- Bug #1267547: Put proper recursive setup.py call into the
234 spec file generated by bdist_rpm.
235
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000236- Bug #1514693: Update turtle's heading when switching between
237 degrees and radians.
238
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000239- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000240 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000241
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000242- Bug #1514703: Only setup canvas window in turtle when the canvas
243 is created.
244
Martin v. Löwis7596e832006-07-01 15:33:37 +0000245- Bug #1513223: .close() of a _socketobj now releases the underlying
246 socket again, which then gets closed as it becomes unreferenced.

249 attribute values.
250
251- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
252 sgmllib ('[' and ']' were not accepted).
253
Georg Brandl1be63af2006-06-28 20:23:25 +0000254- Fix a bug in the turtle module's end_fill function.
255
Brett Cannon53ab5b72006-06-22 16:49:14 +0000256- Bug #1510580: The 'warnings' module improperly required that a Warning
257 category be either a types.ClassType and a subclass of Warning. The proper
258 check is just that it is a subclass with Warning as the documentation states.
259
Georg Brandlad29e632006-06-21 17:45:17 +0000260- The compiler module now correctly compiles the new try-except-finally
261 statement (bug #1509132).
262
Neal Norwitz60373cd2006-06-22 06:30:50 +0000263- The wsgiref package is now installed properly on Unix.
264
Vinay Sajip28e57612006-07-01 10:45:20 +0000265- A bug was fixed in logging.config.fileConfig() which caused a crash on
266 shutdown when fileConfig() was called multiple times.
267
Gerhard Häring762fbd32006-07-02 17:48:30 +0000268- The sqlite3 module did cut off data from the SQLite database at the first
269 null character before sending it to a custom converter. This has been fixed
270 now.
271
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000272Extension Modules
273-----------------
274
Tim Peters112aad32006-07-19 00:03:19 +0000275- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
276 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
277 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000278
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000279- Assigning None to pointer type fields in ctypes structures possible
280 overwrote the wrong fields, this is fixed now.
281
282- Fixed a segfault in _ctypes when ctypes.wintypes were imported
283 on non-Windows platforms.
284
285- Bug #1518190: The ctypes.c_void_p constructor now accepts any
286 integer or long, without range checking.
287
288- Patch #1517790: It is now possible to use custom objects in the ctypes
289 foreign function argtypes sequence as long as they provide a from_param
290 method, no longer is it required that the object is a ctypes type.
291
292- The '_ctypes' extension module now works when Python is configured
293 with the --without-threads option.
294
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000295- Bug #1513646: os.access on Windows now correctly determines write
296 access, again.
297
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000298- Bug #1512695: cPickle.loads could crash if it was interrupted with
299 a KeyboardInterrupt.
300
Neal Norwitza12aa882006-07-06 06:45:08 +0000301- Bug #1296433: parsing XML with a non-default encoding and
302 a CharacterDataHandler could crash the interpreter in pyexpat.
303
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000304- Patch #1516912: improve Modules support for OpenVMS.
305
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000306Build
307-----
308
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000309- Automate Windows build process for the Win64 SSL module.
310
Tim Peters32a83612006-07-10 21:08:24 +0000311- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000312 Previously, the slight difference could cause compilation errors of the
313 'zlib' module on systems with more than one version of zlib.
314
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000315- The MSI compileall step was fixed to also support a TARGETDIR
316 with spaces in it.
317
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000318- Bug #1517388: sqlite3.dll is now installed on Windows independent
319 of Tcl/Tk.
320
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000321- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000322 trying to be installed even though it's empty.

Nick Coghlan2d792252006-07-06 13:47:18 +0000333- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
334 documentation for the warnings module.
335
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000336- Patch #1509163: MS Toolkit Compiler no longer available.
337
Neal Norwitz56640df2006-07-10 02:36:41 +0000338- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000340What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000341================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000342
Anthony Baxterd1136802006-06-19 12:04:15 +0000343*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000344
345Core and builtins
346-----------------
347
Georg Brandla56b9152006-06-19 06:35:54 +0000348- Patch #1507676: Error messages returned by invalid abstract object operations
349 (such as iterating over an integer) have been improved and now include the
350 type of the offending object to help with debugging.
351
Brett Cannonea3912b2006-06-13 21:46:41 +0000352- Bug #992017: A classic class that defined a __coerce__() method that returned
353 its arguments swapped would infinitely recurse and segfault the interpreter.
354
Neal Norwitz909eb122006-06-12 02:13:21 +0000355- Fix the socket tests so they can be run concurrently.
356
Neal Norwitzb9845e72006-06-12 02:11:18 +0000357- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000358 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000359
Brett Cannon22565aa2006-06-09 22:31:23 +0000360- Bug #532646: object.__call__() will continue looking for the __call__
361 attribute on objects until one without one is found. This leads to recursion
362 when you take a class and set its __call__ attribute to an instance of the
363 class. Originally fixed for classic classes, but this fix is for new-style.
364 Removes the infinite_rec_3 crasher.
365
Georg Brandl24250812006-06-09 18:45:48 +0000366- The string and unicode methods startswith() and endswith() now accept
367 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
368
Brett Cannonde3b0522006-06-08 17:00:45 +0000369- Buffer objects, at the C level, never used the char buffer
370 implementation even when the char buffer for the wrapped object was
371 explicitly requested (originally returned the read or write buffer).
372 Now a TypeError is raised if the char buffer is not present but is
373 requested.
374
Georg Brandlddbaa662006-06-04 21:56:52 +0000375- Patch #1346214: Statements like "if 0: suite" are now again optimized
376 away like they were in Python 2.4.
377
Georg Brandlb7c8f542006-05-27 12:30:25 +0000378- Builtin exceptions are now full-blown new-style classes instead of
379 instances pretending to be classes, which speeds up exception handling
380 by about 80% in comparison to 2.5a2.
381
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000382- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
383 Unicode 4.1.
384
Georg Brandlf4ef1162006-05-26 18:03:31 +0000385- Patch #921466: sys.path_importer_cache is now used to cache valid and
386 invalid file paths for the built-in import machinery which leads to
387 fewer open calls on startup.
388
Tim Peters696cf432006-05-24 21:10:40 +0000389- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
390 of-2 bases. The largest speedup is for inputs with about 1000 decimal
391 digits. Conversion from non-power-of-2 bases remains quadratic-time in
392 the number of input digits (it was and remains linear-time for bases
393 2, 4, 8, 16 and 32).
394
Tim Petersb713ec22006-05-23 18:45:30 +0000395- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
396 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
397 an integer close to ``sys.maxint``. This was repaired by patch
398 #1335972, which also gives a nice speedup.
399
Richard Jonescebbefc2006-05-23 18:28:17 +0000400- Patch #1337051: reduced size of frame objects.
401
402- PyErr_NewException now accepts a tuple of base classes as its
403 "base" parameter.
404
Richard Jones7c88dcc2006-05-23 10:37:38 +0000405- Patch #876206: function call speedup by retaining allocated frame
406 objects.
407
Georg Brandl7b90e162006-05-18 07:01:27 +0000408- Bug #1462152: file() now checks more thoroughly for invalid mode
409 strings and removes a possible "U" before passing the mode to the
410 C library function.
411
Neal Norwitz1004a532006-05-15 07:17:23 +0000412- Patch #1488312, Fix memory alignment problem on SPARC in unicode
413
Neal Norwitz373f0a72006-05-15 07:04:36 +0000414- Bug #1487966: Fix SystemError with conditional expression in assignment
415
Martin v. Löwis879768d2006-05-11 13:28:43 +0000416- WindowsError now has two error code attributes: errno, which carries
417 the error values from errno.h, and winerror, which carries the error
418 values from winerror.h. Previous versions put the winerror.h values
419 (from GetLastError()) into the errno attribute.
420
Martin v. Löwis77736712006-05-04 05:51:03 +0000421- Patch #1475845: Raise IndentationError for unexpected indent.
422
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000423- Patch #1479181: split open() and file() from being aliases for each other.
424
Tim Peters44bd9862006-06-01 13:49:23 +0000425- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
426 methods were always silently ignored by dictionaries when comparing keys.
427 They are now passed through (except when using the C API function
428 ``PyDict_GetItem()``, whose semantics did not change).
429
430- Bug #1456209: In some obscure cases it was possible for a class with a
431 custom ``__eq__()`` method to confuse dict internals when class instances
432 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
433 No, you don't have any code that did this ;-)

439
440- Patch #1462338: Upgrade pyexpat to expat 2.0.0
441
Brett Cannon6ee7d012006-06-08 16:23:04 +0000442- Change binascii.hexlify to accept a read-only buffer instead of only a char
443 buffer and actually follow its documentation.
444
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000445- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
446
Nick Coghlanc649ec52006-05-29 12:43:05 +0000447- Patch #1478788 (modified version): The functional extension module has
448 been renamed to _functools and a functools Python wrapper module added.
449 This provides a home for additional function related utilities that are
450 not specifically about functional programming. See PEP 309.
451
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000452- Patch #1493701: performance enhancements for struct module.
453
Georg Brandl378d5922006-05-17 14:26:50 +0000454- Patch #1490224: time.altzone is now set correctly on Cygwin.
455
Georg Brandl8d3342b2006-05-16 07:38:27 +0000456- Patch #1435422: zlib's compress and decompress objects now have a
457 copy() method.
458
Andrew MacIntyre92913322006-06-13 15:04:24 +0000459- Patch #1454481: thread stack size is now tunable at runtime for thread
460 enabled builds on Windows and systems with Posix threads support.
461
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000462- On Win32, os.listdir now supports arbitrarily-long Unicode path names
463 (up to the system limit of 32K characters).
464
465- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
466 As a result, these functions now raise WindowsError instead of OSError.
467
Tim Peters7a822da2006-05-25 21:50:17 +0000468- ``time.clock()`` on Win64 should use the high-performance Windows
469 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
470 Windows platforms).
471
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000472- Calling Tk_Init twice is refused if the first call failed as that
473 may deadlock.
474
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000475- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
476 accept it without potentially using an uninitialized pointer.
477
478- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
479 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
480 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000481
Gregory P. Smith372b5832006-06-05 18:48:21 +0000482- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000483 [pybsddb project SF patch number 1466734]
484
Gregory P. Smith372b5832006-06-05 18:48:21 +0000485- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
486 parameter is supplied. [SF pybsddb bug #1477863]
487
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000488- bsddb: the __len__ method of a DB object has been fixed to return correct
489 results. It could previously incorrectly return 0 in some cases.
490 Fixes SF bug 1493322 (pybsddb bug 1184012).
491
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000492- bsddb: the bsddb.dbtables Modify method now raises the proper error and
493 aborts the db transaction safely when a modifier callback fails.
494 Fixes SF python patch/bug #1408584.
495
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000496- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000497 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000498 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
499 database calls that would previously deadlock. [SF python bug #775414]
500
Vinay Sajip28e57612006-07-01 10:45:20 +0000501- Patch #1446489: add support for the ZIP64 extensions to zipfile.

507-------
508
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000509- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
510 functions.
511
Martin v. Löwis3798da02006-06-17 18:44:27 +0000512- Patch #812986: Update turtle output even if not tracing.
513
Vinay Sajip28e57612006-07-01 10:45:20 +0000514- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000515 Tkinter.BaseWidget.
516
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000517- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
518
Martin v. Löwis337487e2006-06-17 09:15:14 +0000519- Patch #763580: Add name and value arguments to Tkinter variable
520 classes.
521
Georg Brandl83cc0d02006-06-14 08:50:03 +0000522- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
523 mime.types file for determining MIME types.
524
Georg Brandl2605ca82006-06-14 06:08:31 +0000525- Bug #1339007: Shelf objects now don't raise an exception in their
526 __del__ method when initialization failed.
527
Martin v. Löwisd8251432006-06-14 05:21:04 +0000528- Patch #1455898: The MBCS codec now supports the incremental mode for
529 double-byte encodings.
530
Tim Peters43898b42006-06-14 04:09:25 +0000531- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
532 guarantee that adjacent triples in the return list always describe
533 non-adjacent blocks. Previously, a pair of matching blocks could end
534 up being described by multiple adjacent triples that formed a partition
535 of the matching pair.
536
Greg Ward0e0c9f42006-06-11 16:24:11 +0000537- Bug #1498146: fix optparse to handle Unicode strings in option help,
538 description, and epilog.
539
Greg Wardd1c797e2006-06-11 14:42:41 +0000540- Bug #1366250: minor optparse documentation error.
541
Greg Ward7f547402006-06-11 00:40:49 +0000542- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
543 clarify docs.
544
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000545- The wsgiref package has been added to the standard library.
546
Nick Coghlan676725d2006-06-08 13:54:49 +0000547- The functions update_wrapper() and wraps() have been added to the functools
548 module. These make it easier to copy relevant metadata from the original
549 function when writing wrapper functions.
550
Tim Petersd6a9eef2006-06-05 01:48:21 +0000551- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
552 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000553
Martin v. Löwis3f767792006-06-04 19:36:28 +0000554- Patch #1359618: Speed up charmap encoder by using a trie structure
555 for lookup.
556
Tim Petersd609b1a2006-06-02 23:22:51 +0000557- The functions in the ``pprint`` module now sort dictionaries by key
558 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
559 if and only if its display required more than one line, although that
560 wasn't documented. The new behavior increases predictability; e.g.,
561 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
562
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000563- Patch #1497027: try HTTP digest auth before basic auth in urllib2
564 (thanks for J. J. Lee).
565
Georg Brandl2b330372006-05-28 20:23:12 +0000566- Patch #1496206: improve urllib2 handling of passwords with respect to
567 default HTTP and HTTPS ports.
568
George Yoshidaf3c65de2006-05-28 16:39:09 +0000569- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
570
Bob Ippolito7298f272006-05-23 18:43:47 +0000571- Patch #1281707: speed up gzip.readline.
572
Georg Brandlb89316f2006-05-17 15:51:16 +0000573- Patch #1180296: Two new functions were added to the locale module:
574 format_string() to get the effect of "format % items" but locale-aware,
575 and currency() to format a monetary number with currency sign.
576
Georg Brandle3a25832006-05-17 14:56:04 +0000577- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
578 and several features added, such as speed and geometry control.
579
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000580- Patch #1488881: add support for external file objects in bz2 compressed
581 tarfiles.
582
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000583- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
584 stdout arguments, making it possible to redirect input and output
585 for remote debugging.
586
587- Patch #1484695: Update the tarfile module to version 0.8. This fixes
588 a couple of issues, notably handling of long file names using the
589 GNU LONGNAME extension.
590
591- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
592 new flag when ``name`` is already the name of an option flag.
593
594- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
595 package.
596
597- Patch #1472854: make the rlcompleter.Completer class usable on non-
598 UNIX platforms.
599
600- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
601
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000602- Bug #1472827: correctly escape newlines and tabs in attribute values in
603 the saxutils.XMLGenerator class.

Martin v. Löwisa43190b2006-05-22 09:15:18 +0000613- Patch #1492356: Port to Windows CE.
614
Neal Norwitz58e28882006-05-19 07:00:58 +0000615- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000633What's New in Python 2.5 alpha 2?
634=================================
635
636*Release date: 27-APR-2006*
637
638Core and builtins
639-----------------
640
Thomas Heller1b046642006-04-18 18:51:06 +0000641- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
642 by converting these apis from macros into exported functions again:
643
644 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
645 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
646 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
647 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
648 PyRun_String Py_CompileString
649
Martin v. Löwis45294a92006-04-18 06:24:08 +0000650- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
651
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000652- All uses of PyStructSequence_InitType have been changed to initialize
653 the type objects only once, even if the interpreter is initialized
654 multiple times.
655
Neal Norwitz61546162006-04-14 05:20:28 +0000656- Bug #1454485, array.array('u') could crash the interpreter. This was
657 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
658 to unicode when it didn't make sense. 'u#' now requires a unicode string.
659
660- Py_UNICODE is unsigned. It was always documented as unsigned, but
661 due to a bug had a signed value in previous versions.
662
Tim Peters3a5e8b12006-04-11 01:44:07 +0000663- Patch #837242: ``id()`` of any Python object always gives a positive
664 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
665 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000666 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000667 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000668
Tim Peters3a5e8b12006-04-11 01:44:07 +0000669 def __hash__(self):
670 return id(self) # WRONG
671
672 because a hash result must be a (short) Python int but it was always
673 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000674 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000675 was always usable as a hash value before this patch. That's no longer
676 necessarily so.
677
678- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000679 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000680 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000681 #1454844)
682
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000683- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
684 involving generators that have paused outside of any ``try`` or ``with``
685 blocks. (In 2.5a1, a paused generator that was part of a reference
686 cycle could not be garbage collected, regardless of whether it was
687 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +0000688
Anthony Baxter51bcb682006-04-05 14:51:42 +0000689Extension Modules
690-----------------
691
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000692- Patch #1191065: Fix preprocessor problems on systems where recvfrom
693 is a macro.
694
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000695- Bug #1467952: os.listdir() now correctly raises an error if readdir()
696 fails with an error condition.
697
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000698- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
699
700- Bug #1117761: bsddb.*open() no longer raises an exception when using
701 the cachesize parameter.
702
703- Bug #1149413: bsddb.*open() no longer raises an exception when using
704 a temporary db (file=None) with the 'n' flag to truncate on open.
705
706- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
707 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000708
Armin Rigoa9017c32006-04-19 11:50:27 +0000709- Patch #1062014: AF_UNIX sockets under Linux have a special
710 abstract namespace that is now fully supported.
711
Anthony Baxter51bcb682006-04-05 14:51:42 +0000712Library
713-------
714
Peter Astrand7d1d4362006-07-14 14:04:45 +0000715- Bug #1223937: subprocess.CalledProcessError reports the exit status
716 of the process using the returncode attribute, instead of
717 abusing errno.
718
Tim Peters711bf302006-04-25 03:31:36 +0000719- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
720 a doctest to be skipped (the code is not run, and the expected output
721 or exception is ignored).
722
Nick Coghlanda2268f2006-04-24 04:37:15 +0000723- Fixed contextlib.nested to cope with exceptions being raised and
724 caught inside exit handlers.
725
Greg Wardab05edc2006-04-23 03:47:58 +0000726- Updated optparse module to Optik 1.5.1 (allow numeric constants in
727 hex, octal, or binary; add ``append_const`` action; keep going if
728 gettext cannot be imported; added ``OptionParser.destroy()`` method;
729 added ``epilog`` for better help generation).
730
Tim Peters21fbd572006-04-21 21:18:10 +0000731- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
732 called from a thread spawned as a side effect of importing a module.
733
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000734- The pydoc module now supports documenting packages contained in
735 .zip or .egg files.
736
737- The pkgutil module now has several new utility functions, such
738 as ``walk_packages()`` to support working with packages that are either
739 in the filesystem or zip files.
740
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000741- The mailbox module can now modify and delete messages from
742 mailboxes, in addition to simply reading them. Thanks to Gregory
743 K. Johnson for writing the code, and to the 2005 Google Summer of
744 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000745
Tim Petersc7605f22006-04-17 21:12:33 +0000746- The ``__del__`` method of class ``local`` in module ``_threading_local``
747 returned before accomplishing any of its intended cleanup.
748
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000749- Patch #790710: Add breakpoint command lists in pdb.
750
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000751- Patch #1063914: Add Tkinter.Misc.clipboard_get().
752
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000753- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
754
Anthony Baxtere29002c2006-04-12 12:07:31 +0000755- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
756 Windows. Bug #1469163.
757
Phillip J. Eby47032112006-04-11 01:07:43 +0000758- The warnings, linecache, inspect, traceback, site, and doctest modules
759 were updated to work correctly with modules imported from zipfiles or
760 via other PEP 302 __loader__ objects.
761
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000762- Patch #1467770: Reduce usage of subprocess._active to processes which
763 the application hasn't waited on.
764
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000765- Patch #1462222: Fix Tix.Grid.
766
Neal Norwitza31bf182006-04-09 03:35:43 +0000767- Fix exception when doing glob.glob('anything*/')
768
Skip Montanaro262fb922006-04-21 02:31:07 +0000769- The pstats.Stats class accepts an optional stream keyword argument to
770 direct output to an alternate file-like object.
771
Anthony Baxter51bcb682006-04-05 14:51:42 +0000772Build
773-----
774
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000775- The Makefile now has a reindent target, which runs reindent.py on
776 the library.
777
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000778- Patch #1470875: Building Python with MS Free Compiler
779
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000780- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000781
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000782- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
783 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000784 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000785 CXX from --with-cxx-main, see description in README.
786
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000787- Patch #1429775: Link extension modules with the shared libpython.
788
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000789- Fixed a libffi build problem on MIPS systems.
790
Tim Peters8931ff12006-05-13 23:28:20 +0000791- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
792 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
793 and "%zu" for unsigned integers of type ``size_t``.
794
Anthony Baxter51bcb682006-04-05 14:51:42 +0000795Tests
796-----
797
Nick Coghlanda2268f2006-04-24 04:37:15 +0000798- test_contextlib now checks contextlib.nested can cope with exceptions
799 being raised and caught inside exit handlers.
800
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000801- test_cmd_line now checks operation of the -m and -c command switches
802
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000803- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
804 it separately and by hand. It also wasn't cleaning up its changes to
805 the current Decimal context.
806
Thomas Woutersabd08882006-04-26 15:53:30 +0000807- regrtest.py now has a -M option to run tests that test the new limits of
808 containers, on 64-bit architectures. Running these tests is only sensible
809 on 64-bit machines with more than two gigabytes of memory. The argument
810 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000818Documentation
819-------------
820
Tim Petersb06d28c2006-05-12 01:57:59 +0000821- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
822
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000823- PEP 343: Added Context Types section to the library reference
824 and attempted to bring other PEP 343 related documentation into
825 line with the implementation and/or python-dev discussions.
826
Tim Peters8dc73d22006-04-24 02:03:16 +0000827- Bug #1337990: clarified that ``doctest`` does not support examples
828 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000831What's New in Python 2.5 alpha 1?
832=================================
833
Anthony Baxterebed3f62006-04-03 15:03:44 +0000834*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000835
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000836Core and builtins
837-----------------
838
Nick Coghlan43832302006-04-23 17:04:07 +0000839- PEP 338: -m command line switch now delegates to runpy.run_module
840 allowing it to support modules in packages and zipfiles
841
Martin v. Löwisc661b882006-04-20 04:54:23 +0000842- On Windows, .DLL is not an accepted file name extension for
843 extension modules anymore; extensions are only found if they
844 end in .PYD.
845
Martin v. Löwisea62d252006-04-03 10:56:49 +0000846- Bug #1421664: sys.stderr.encoding is now set to the same value as
847 sys.stdout.encoding.
848
Neal Norwitz92e212f2006-04-03 04:48:37 +0000849- __import__ accepts keyword arguments.
850
Georg Brandlccadf842006-03-31 18:54:53 +0000851- Patch #1460496: round() now accepts keyword arguments.
852
Anthony Baxter262c00a2006-03-30 10:53:17 +0000853- Fixed bug #1459029 - unicode reprs were double-escaped.
854
Hye-Shik Changd478f342006-03-23 12:32:36 +0000855- Patch #1396919: The system scope threads are reenabled on FreeBSD
856 5.4 and later versions.
857
Neal Norwitze98ccf62006-03-23 05:39:47 +0000858- Bug #1115379: Compiling a Unicode string with an encoding declaration
859 now gives a SyntaxError.
860
Georg Brandlabd1ff82006-03-18 07:59:59 +0000861- Previously, Python code had no easy way to access the contents of a
862 cell object. Now, a ``cell_contents`` attribute has been added
863 (closes patch #1170323).
864
Tim Peterscf79aac2006-03-16 01:14:46 +0000865- Patch #1123430: Python's small-object allocator now returns an arena to
866 the system ``free()`` when all memory within an arena becomes unused
867 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
868 freed. Some applications will see a drop in virtual memory size now,
869 especially long-running applications that, from time to time, temporarily
870 use a large number of small objects. Note that when Python returns an
871 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000872 platform C library will in turn return that memory to the operating system.
873 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000874 appears to be effective at least on Microsoft C and gcc-based systems.
875 Thanks to Evan Jones for hard work and patience.
876
Georg Brandl533ff6f2006-03-08 18:09:27 +0000877- Patch #1434038: property() now uses the getter's docstring if there is
878 no "doc" argument given. This makes it possible to legitimately use
879 property() as a decorator to produce a read-only property.
880
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000881- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
882 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
883 of requiring an int or long in slicing and a few other contexts, enabling
884 other objects (e.g. Numeric Python's integers) to be used as slice indices.
885
Neal Norwitz995acdf2006-03-07 05:01:00 +0000886- Fixed various bugs reported by Coverity's Prevent tool.
887
Brett Cannonbf364092006-03-01 04:25:17 +0000888- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
889 new exception base class, BaseException, which has a new message attribute.
890 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
891 Raising a string exception now raises a DeprecationWarning.
892
Thomas Woutersfb609f42006-02-28 16:37:25 +0000893- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
894 explicitly relative, using 'from .module import name' to mean 'from the same
895 package as this module is in. Imports without dots still default to the
896 old relative-then-absolute, unless 'from __future__ import
897 absolute_import' is used.
898
Brett Cannona7446e32006-02-27 23:39:10 +0000899- Properly check if 'warnings' raises an exception (usually when a filter set
900 to "error" is triggered) when raising a warning for raising string
901 exceptions.
902
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000903- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000904 The name was removed from Include/code.h.
905
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000906- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000907
Guido van Rossum1968ad32006-02-25 22:38:04 +0000908- Patch 1433928:
909 - The copy module now "copies" function objects (as atomic objects).
910 - dict.__getitem__ now looks for a __missing__ hook before raising
911 KeyError.
912
Tim Peters84ef21c2006-02-28 20:39:06 +0000913- PEP 343: with statement implemented. Needs ``from __future__ import
914 with_statement``. Use of 'with' as a variable will generate a warning.
915 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000916 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000917 The following objects have __context__ methods:
918 - The built-in file type.
919 - The thread.LockType type.
920 - The following types defined by the threading module:
921 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
922 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000923
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000924- Fix the encodings package codec search function to only search
925 inside its own package. Fixes problem reported in patch #1433198.

927 Note: Codec packages should implement and register their own
928 codec search function. PEP 100 has the details.

Tim Peters9ea89d22006-06-04 03:26:02 +0000930- PEP 353: Using ``Py_ssize_t`` as the index type.
931
932- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
933 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
934 now allow Python to make use of memory blocks exceeding 2**32 bytes for
935 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
936 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000937
Neal Norwitzfc76d632006-01-10 06:03:13 +0000938- Patch #1400181, fix unicode string formatting to not use the locale.
939 This is how string objects work. u'%f' could use , instead of .
940 for the decimal point. Now both strings and unicode always use periods.
941
Neal Norwitz671b9e32006-01-09 07:07:12 +0000942- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
943 configure would break checking curses.h.
944
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000945- Bug #959576: The pwd module is now builtin. This allows Python to be
946 built on UNIX platforms without $HOME set.
947
Neal Norwitzc10978f2005-12-19 06:07:16 +0000948- Bug #1072182, fix some potential problems if characters are signed.
949
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000950- Bug #889500, fix line number on SyntaxWarning for global declarations.
951
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000952- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
953
Neal Norwitze7214a12005-12-18 05:03:17 +0000954- Support for converting hex strings to floats no longer works.
955 This was not portable. float('0x3') now raises a ValueError.
956
Barry Warsaw2a38a862005-12-18 01:27:35 +0000957- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000958 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000959 is now displayed in interactive prompt banner.
960
Georg Brandlfa166682005-12-17 21:45:17 +0000961- Implementation of PEP 341 - Unification of try/except and try/finally.
962 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000963 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000964
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000965- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
966 now encodes backslash correctly.
967
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000968- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
969
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000970- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000971 and long longs.
972
Neal Norwitz67715f02005-11-09 06:59:35 +0000973- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000974 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000975 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000976
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000977- Replaced most Unicode charmap codecs with new ones using the
978 new Unicode translate string feature in the builtin charmap
979 codec; the codecs were created from the mapping tables available
980 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
981 encodings now include a mapping for the Apple logo)
982
Tim Peterse3547fd2005-12-16 23:13:57 +0000983- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000984
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000985- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000986
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000987- A new AST parser implementation was completed. The abstract
988 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000989 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000990
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000991- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000992 The following code now raises a SyntaxError: foo(a = i for i in range(10))
993
Neal Norwitz708e51a2005-10-03 04:48:15 +0000994- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
995
Neal Norwitz11bd1192005-10-03 00:54:56 +0000996- SF Bug #887946: fix segfault when redirecting stdin from a directory.
997 Provide a warning when a directory is passed on the command line.
998
Neal Norwitz40d37812005-10-02 01:48:49 +0000999- Fix segfault with invalid coding.
1000
1001- SF bug #772896: unknown encoding results in MemoryError.
1002
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001003- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001004 supported a __len__() method which evaluated to False when the iterator
1005 was empty.
1006
Guido van Rossum630db602005-09-20 18:49:54 +00001007- On 64-bit platforms, when __len__() returns a value that cannot be
1008 represented as a C int, raise OverflowError.
1009
Skip Montanarof8948ca2005-09-19 03:54:46 +00001010- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001011 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001012
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001013- SF bug #893549: parsing keyword arguments was broken with a few format
1014 codes.
1015
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001016- Changes donated by Elemental Security to make it work on AIX 5.3
1017 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1018 bug #105470: test_pwd fails on 64bit system (Opteron).
1019
Guido van Rossum539c6622005-09-14 17:49:54 +00001020- Changes donated by Elemental Security to make it work on HP-UX 11 on
1021 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1022
Georg Brandl4550b8d2005-08-26 06:43:52 +00001023- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001024 (fixes bug #1119418).
1025
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001026- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1027
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001028- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1029 exceptions that cause a function to exit.
1030
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001031- The implementation of set() and frozenset() was revised to use its
1032 own internal data structure. Memory consumption is reduced by 1/3
1033 and there are modest speed-ups as well. The API is unchanged.
1034
Tim Petersde7990b2005-07-17 23:45:23 +00001035- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1036
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001037- SF bug #1229429: PyObject_CallMethod failed to decrement some
1038 reference counts in some error exit cases.
1039
Tim Petersecc6e6a2005-07-10 22:30:55 +00001040- SF bug #1185883: Python's small-object memory allocator took over
1041 a block managed by the platform C library whenever a realloc specified
1042 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001043 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001044 portable way to copy data from the C-managed block into Python's
1045 small-object space without risking a memory fault. Python's small-object
1046 realloc now leaves such blocks under the control of the platform C
1047 realloc.
1048
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001049- SF bug #1232517: An overflow error was not detected properly when
1050 attempting to convert a large float to an int in os.utime().
1051
Raymond Hettinger3296e692005-06-29 23:29:56 +00001052- SF bug #1224347: hex longs now print with lowercase letters just
1053 like their int counterparts.
1054
Michael W. Hudson188d4362005-06-20 16:52:57 +00001055- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1056 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1057 interpreter states; back out that fix and do a better job (see
1058 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1059 for a longer write-up of the problem).
1060
Michael W. Hudsondf888462005-06-03 14:41:55 +00001061- SF patch #1180995: marshal now uses a binary format by default when
1062 serializing floats.
1063
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001064- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1065 the routines that promise to produce IEEE 754 binary representations
1066 of floats now simply copy bytes around.
1067
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001068- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1069 278.
1070
Brett Cannonc3647ac2005-04-26 03:45:26 +00001071- patch #1109424: int, long, float, complex, and unicode now check for the
1072 proper magic slot for type conversions when subclassed. Previously the
1073 magic slot was ignored during conversion. Semantics now match the way
1074 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001075 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001076 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001077 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001078
Barry Warsawc8d907c2005-04-19 23:43:40 +00001079- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1080 NULL, now raise an AttributeError when attempting to set or delete the
1081 attribute. Previously a TypeError was raised, but this was inconsistent
1082 with the equivalent pure-Python implementation.
1083
Michael W. Hudson774479c2005-04-18 08:46:17 +00001084- It is now safe to call PyGILState_Release() before
1085 PyEval_InitThreads() (note that if there is reason to believe there
1086 are multiple threads around you still must call PyEval_InitThreads()
1087 before using the Python API; this fix is for extension modules that
1088 have no way of knowing if Python is multi-threaded yet).
1089
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001090- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1091 disabled caused a crash.
1092
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001093- Bug #1165306: instancemethod_new allowed the creation of a method
1094 with im_class == im_self == NULL, which caused a crash when called.
1095
Tim Petersecc6e6a2005-07-10 22:30:55 +00001096- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001097 fixes the crash seen in bug #1165761
1098
Raymond Hettinger96229b12005-03-11 06:49:40 +00001099- Added two new builtins, any() and all().
1100
Brett Cannon409d8f22005-03-05 06:47:57 +00001101- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001102 (e.g., ``class C(): pass`` is no longer a syntax error).
1103 Patch #1176012 added support to the 'parser' module and 'compiler' package
1104 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001105
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001106- Patch #1115086: Support PY_LONGLONG in structmember.
1107
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001108- Bug #1155938: new style classes did not check that __init__() was
1109 returning None.
1110
Tim Petersecc6e6a2005-07-10 22:30:55 +00001111- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001112 ('\') with a specific error message.
1113
Martin v. Löwisff232d72005-03-03 09:24:38 +00001114- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1115
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001116- Bug #1124295: the __name__ attribute of file objects was
1117 inadvertently made inaccessible in restricted mode.
1118
Tim Petersecc6e6a2005-07-10 22:30:55 +00001119- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001120 an ferror() call.
1121
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001122- min() and max() now support key= arguments with the same meaning as in
1123 list.sort().
1124
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001125- The peephole optimizer now performs simple constant folding in expressions:
1126 (2+3) --> (5).
1127
Raymond Hettingera422c342005-01-11 03:03:27 +00001128- set and frozenset objects can now be marshalled. SF #1098985.
1129
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001130- Bug #1077106: Poor argument checking could cause memory corruption
1131 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001132
Jeremy Hyltonab630502005-02-04 18:44:06 +00001133- The parser did not complain about future statements in illegal
1134 positions. It once again reports a syntax error if a future
1135 statement occurs after anything other than a doc string.
1136
Neil Schemenauercf52c072005-08-12 17:34:58 +00001137- Change the %s format specifier for str objects so that it returns a
1138 unicode instance if the argument is not an instance of basestring and
1139 calling __str__ on the argument returns a unicode instance.
1140
Tim Petersf4e69282006-02-27 17:15:31 +00001141- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1142 current thread state when the auto-GIL-state machinery knows about
1143 it (since the thread state is being deleted, continuing to remember it
1144 can't help, but can hurt if another thread happens to get created with
1145 the same thread id).
1146
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001147Extension Modules
1148-----------------
1149
Georg Brandl43f08a82006-03-31 18:01:16 +00001150- Patch #1380952: fix SSL objects timing out on consecutive read()s
1151
Neal Norwitz05a45592006-03-20 06:30:08 +00001152- Patch #1309579: wait3 and wait4 were added to the posix module.
1153
Anthony Baxterfa869072006-03-20 05:21:58 +00001154- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1155 In addition, the existing ulaw code was updated.
1156
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001157- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001158 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001159
Neal Norwitz10be10c2006-03-16 06:50:13 +00001160- Everything under lib-old was removed. This includes the following modules:
1161 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001162 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001163 util, whatsound, whrandom, zmod
1164
1165- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1166
1167- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001168 is deprecated. The undocumented re.engine variable no longer exists.
1169
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001170- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1171 SS2 (single-shift 2) escape sequences correctly.
1172
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001173- The unicodedata module was updated to the 4.1 version of the Unicode
1174 database. The 3.2 version is still available as unicodedata.db_3_2_0
1175 for applications that require this specific version (such as IDNA).
1176
Neal Norwitzb62c4332006-03-04 18:35:47 +00001177- The timing module is no longer built by default. It was deprecated
1178 in PEP 4 in Python 2.0 or earlier.
1179
Guido van Rossum1968ad32006-02-25 22:38:04 +00001180- Patch 1433928: Added a new type, defaultdict, to the collections module.
1181 This uses the new __missing__ hook behavior added to dict (see above).
1182
Georg Brandldbd83392006-02-20 09:42:33 +00001183- Bug #854823: socketmodule now builds on Sun platforms even when
1184 INET_ADDRSTRLEN is not defined.
1185
Georg Brandlf4f44152006-02-18 22:29:33 +00001186- Patch #1393157: os.startfile() now has an optional argument to specify
1187 a "command verb" to invoke on the file.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001337- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1338 been renamed to have only a single underscore prefix. This was done to
1339 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001340
Nick Coghlan43832302006-04-23 17:04:07 +00001341- PEP 338: new module runpy defines a run_module function to support
1342 executing modules which provide access to source code or a code object
1343 via the PEP 302 import mechanisms.
1344
Anthony Baxter93f5b932006-04-03 08:05:07 +00001345- The email module's parsedate_tz function now sets the daylight savings

1353 in attribute values.
1354
Anthony Baxterc51ee692006-04-01 00:57:31 +00001355- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001356 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001357 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001358 module will not be built.
1359
Tim Petersc17976e2006-04-01 00:26:53 +00001360- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1361 aren't officially supported here, and trying to use them will probably
1362 raise an exception some day. But dicts have been allowed, and "mostly
1363 worked", so support for them won't go away without warning.
1364
Georg Brandl338ef7d2006-03-31 18:42:16 +00001365- Bug #1445068: getpass.getpass() can now be given an explicit stream

1383
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001384- email 4.0 package now integrated. This is largely the same as the email 3.0
1385 package that was included in Python 2.3, except that PEP 8 module names are
1386 now used (e.g. mail.message instead of email.Message). The MIME classes
1387 have been moved to a subpackage (e.g. email.mime.text instead of
1388 email.MIMEText). The old names are still supported for now. Several
1389 deprecated Message methods have been removed and lots of bugs have been
1390 fixed. More details can be found in the email package documentation.
1391
Walter Dörwald40108c92006-03-27 08:15:44 +00001392- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1393 (a subclass of tuple) that provides incremental decoders and encoders
1394 (a way to use stateful codecs without the stream API). Python functions
1395 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1396 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1397 have been added.

1400 a ValueError instead of a StopIteration now (like file and cString.String do).

1470
Neal Norwitz338e7862005-12-23 21:27:46 +00001471- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1472 LoadError as documented, instead of IOError. For compatibility,
1473 LoadError subclasses IOError.
1474
Brett Cannon3cbd0382005-12-16 22:49:23 +00001475- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001476 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1477 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1478 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1479 Ronald L. Rivest offered this advice for Python:
1480
1481 "The consensus of researchers in this area (at least as
1482 expressed at the NIST Hash Function Workshop 10/31/05),
1483 is that SHA-256 is a good choice for the time being, but
1484 that research should continue, and other alternatives may
1485 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001486
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001487- Added a subset of Fredrik Lundh's ElementTree package. Available

1540 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001541 correct line numbers for decoding errors in source code.

1564 to W3C name (404 -> 'Not Found'). RFE #1216944.
1565
Georg Brandl9e43acf2005-07-04 17:16:07 +00001566- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1567 as this can cause problems with apps closing all file descriptors.

1580 Bug #1224621.
1581
Raymond Hettinger68c04532005-06-10 11:05:19 +00001582- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001583 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001584 the generate_tokens() function now accepts a callable argument that
1585 terminates by raising StopIteration.
1586
Georg Brandl9166e1a2005-06-04 09:20:03 +00001587- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1591
Skip Montanaro174dd222005-05-14 20:54:16 +00001592- Patch #1120353: The xmlrpclib module provides better, more transparent,

1595 class at all.
1596
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001597- distutils.commands.upload was added to support uploading distribution

1601 them to PyPI.
1602
Raymond Hettinger267b8682005-03-27 10:47:39 +00001603- decimal operator and comparison methods now return NotImplemented
1604 instead of raising a TypeError when interacting with other types. This
1605 allows other classes to implement __radd__ style methods and have them
1606 work as expected.
1607
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001608- Bug #1163325: Decimal infinities failed to hash. Attempting to
1609 hash a NaN raised an InvalidOperation instead of a TypeError.
1610
Tim Petersecc6e6a2005-07-10 22:30:55 +00001611- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1645
Guido van Rossumd0641422005-02-03 15:01:24 +00001646- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1647 disables recursive traversal through instance attributes, which can
1648 be exploited in various ways.
1649
Tim Peterse3547fd2005-12-16 23:13:57 +00001650- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001651 flags on the HTTP listening socket.
1652
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001653- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1654 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1655
Fred Drakefbdeaad2006-07-29 16:56:15 +00001656- Patches #893642, #1039083: add allow_none, encoding arguments to
1657 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001658

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001661- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1662
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001663- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1664
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001665- Enhancements to the csv module:
1666
1667 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001668 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001669 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001670 + Dialect parameter parsing has been re-implemented to improve error
1671 reporting.
1672 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1673 dictates.
1674 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001675 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001676 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001677 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1678 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001679 + reader now allows \r characters to be quoted (previously it only allowed
1680 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001681 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001682 + Dialect classes passed to the module are no longer instantiated by
1683 the module before being parsed (the former validation scheme required
1684 this, but the mechanism was unreliable).
1685 + The dialect registry now contains instances of the internal
1686 C-coded dialect type, rather than references to python objects.
1687 + the internal c-coded dialect type is now immutable.
1688 + register_dialect now accepts the same keyword dialect specifications
1689 as the reader and writer, allowing the user to register dialects
1690 without first creating a dialect class.
1691 + a configurable limit to the size of parsed fields has been added -
1692 previously, an unmatched quote character could result in the entire
1693 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001694 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001695 the parser field size limit (returning the former limit). The initial
1696 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001697 + A line_num attribute has been added to the reader object, which tracks
1698 the number of lines read from the source iterator. This is not
1699 the same as the number of records returned, as records can span
1700 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001701 + reader and writer objects were not being registered with the cyclic-GC.
1702 This has been fixed.
1703
Brett Cannone6539c42005-01-08 02:43:53 +00001704- _DummyThread objects in the threading module now delete self.__block that is
1705 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1706 lock primitives tend to be limited in number and thus should not be wasted on
1707 a _DummyThread object. Fixes bug #1089632.
1708
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001709- The imghdr module now detects Exif files.
1710
Raymond Hettinger6065d322004-12-20 23:51:53 +00001711- StringIO.truncate() now correctly adjusts the size attribute.
1712 (Bug #951915).
1713
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001714- locale.py now uses an updated locale alias table (built using
1715 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1716 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001717 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001718
Raymond Hettinger3557f422004-12-07 12:02:02 +00001719- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1720
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001721- the pickle module no longer accepts the deprecated None option in the
1722 args tuple returned by __reduce__().
1723
Brett Cannon84667c02004-12-07 03:25:18 +00001724- optparse now optionally imports gettext. This allows its use in setup.py.
1725
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001726- the pickle module no longer uses the deprecated bin parameter.
1727
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001728- the shelve module no longer uses the deprecated binary parameter.
1729
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001730- the pstats module no longer uses the deprecated ignore() method.
1731
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001732- the filecmp module no longer uses the deprecated use_statcache argument.
1733
Raymond Hettinger664347b2004-12-04 21:21:53 +00001734- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1735 extended or overridden by subclasses. Formerly, the subclassed method would
1736 be ignored by the rest of the module. (Bug #1078905).
1737
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001738- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001739 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001740
Walter Dörwald36733692004-12-22 12:50:50 +00001741- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1742 once when a size argument is given. This prevents a buffer overflow in the
1743 tokenizer with very long source lines.
1744
Barry Warsaw538561e2006-01-01 21:48:54 +00001745- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1746 immediately after creating the object, without any intervening
1747 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001748
Skip Montanaro05885812005-01-16 20:48:27 +00001749- The reconvert.quote function can now emit triple-quoted strings. The
1750 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001751
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001752- ``UserString.MutableString`` now supports negative indices in
1753 ``__setitem__`` and ``__delitem__``
1754
Greg Ward40407942005-03-05 02:53:17 +00001755- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1756 correctly.
1757
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001758- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1759 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1760 character even if the user has passed a size parameter to get a proper
1761 line ending. Remove the special handling of a "\r\n" that has been split
1762 between two lines.
1763
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001764- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1765 about illegal code points. The codec now supports PEP 293 style error
1766 handlers.
1767
Walter Dörwald78a78b02005-09-01 12:04:29 +00001768- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001769 from the input stream, so that the output is a byte string in the correct
1770 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001771
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001772- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1773 considering it exactly like a '*'.
1774
Walter Dörwald007f8df2005-10-09 19:42:27 +00001775- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1776 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001777
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001778- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1779
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001780- Patch #1413711: Certain patterns of differences were making difflib
1781 touch the recursion limit.
1782
Walter Dörwald58917a62006-03-31 15:26:22 +00001783- Bug #947906: An object oriented interface has been added to the calendar
1784 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001785 called as a script (e.g. via ``python -mcalendar``). Localized month and
1786 weekday names can be ouput (even if an exotic encoding is used) using
1787 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001788
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001789Build
1790-----
1791
Neal Norwitz602d3392006-03-31 08:21:40 +00001792- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1793 by using -mieee gcc option.
1794
Martin v. Löwis86d66262006-02-17 08:40:11 +00001795- Patch #1432345: Make python compile on DragonFly.
1796
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001797- Build support for Win64-AMD64 was added.
1798
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001799- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1800
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001801- Patch #881820: look for openpty and forkpty also in libbsd.
1802
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001803- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1804 The zlib module is now builtin on Windows.
1805
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001806- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1807
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001808- Bug #1189330: configure did not correctly determine the necessary
1809 value of LINKCC if python was built with GCC 4.0.
1810
Trent Mick8321b422005-07-26 02:29:21 +00001811- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1812 vulnerability in zlib 1.2.1 and 1.2.2.
1813
Brett Cannon08cd5982005-04-24 22:26:38 +00001814- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1815 flags that change binary compatibility. Changes were also made to
1816 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001817 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001818
Bob Ippolitoed233462005-03-29 13:47:59 +00001819- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1820 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1821 no longer exists). This configure patch makes things right.
1822
Martin v. Löwise2713be2005-03-08 15:03:08 +00001823- Bug #1158607: Build with --disable-unicode again.
1824
Brett Cannon46d96232005-02-16 00:07:19 +00001825- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1826 defined. Discovered as a result of not being able to build on OS X.
1827
Brett Cannon516592f2004-12-07 00:42:59 +00001828- setup.py now uses the directories specified in LDFLAGS using the -L option
1829 and in CPPFLAGS using the -I option for adding library and include
1830 directories, respectively, for compiling extension modules against. This has
1831 led to the core being compiled using the values in CPPFLAGS. It also removes
1832 the need for the special-casing of both DarwinPorts and Fink for darwin since
1833 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1834 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1835 Fink, ``-I/opt/local/include`` for DarwinPorts).
1836
Brett Cannon43802422005-02-10 20:48:03 +00001837- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1838 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1839 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1840 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001842C API
1843-----
1844
Tim Petersc9d78aa2006-03-26 23:27:58 +00001845- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1846 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1847 is obtained via the ``PyObject_`` family, it must be released via the
1848 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1849 always been officially true, but when Python's small-object allocator was
1850 introduced, an attempt was made to cater to a few extension modules
1851 discovered at the time that obtained memory via ``PyObject_New`` but
1852 released it via ``PyMem_DEL``. It's years later, and if such code still
1853 exists it will fail now (probably with segfaults, but calling wrong
1854 low-level memory management functions can yield many symptoms).
1855
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001856- Added a C API for set and frozenset objects.
1857
Raymond Hettinger66517482004-12-03 11:45:13 +00001858- Removed PyRange_New().
1859
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001860- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1861 mapping argument now. This string is used as a mapping table. Byte values
1862 greater than the length of the string and 0xFFFE are treated as undefined
1863 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001869- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001870
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001871- Patch #1276356: New resource "urlfetch" is implemented. This enables
1872 even impatient people to run tests that require remote files.
