Guido van Rossumc69ac252006-08-10 18:09:25 +00007What's New in Python 2.5 release candidate 1?
8=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +00009
Guido van Rossum133f4e42006-08-10 17:42:50 +000010*Release date: 18-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +000011
12Core and builtins
13-----------------
14
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000015- Unicode objects will no longer raise an exception when being
16 compared equal or unequal to a string and causing a
17 UnicodeDecodeError exception, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +000018
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000019 Instead, the equal (==) and unequal (!=) comparison operators will
20 now issue a UnicodeWarning and interpret the two objects as
21 unequal. The UnicodeWarning can be filtered as desired using
22 the warning framework, e.g. silenced completely, turned into an
23 exception, logged, etc.
24
25 Note that compare operators other than equal and unequal will still
26 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +000027
Marc-André Lemburg757ea272006-08-14 11:44:34 +000028- Fix segfault when doing string formatting on subclasses of long.
29
30- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
31 with new-style classes.
32
33- Fix bug related to __len__ functions returning negative values with
34 classic classes.
35
36- Patch #1538606, Fix __index__() clipping. There were some problems
37 discovered with the API and how integers that didn't fit into Py_ssize_t
38 were handled. This patch attempts to provide enough alternatives
39 to effectively use __index__.
40
Martin v. Löwisab2f8f72006-08-09 07:57:39 +000041- Bug #1536021: __hash__ may now return long int; the final hash
42 value is obtained by invoking hash on the long int.
43
Thomas Hellerab1049c2006-08-08 17:37:00 +000044- Bug #1536786: buffer comparison could emit a RuntimeWarning.
45
Georg Brandl7e3ba2a2006-08-06 08:23:54 +000046- Bug #1535165: fixed a segfault in input() and raw_input() when
47 sys.stdin is closed.
48
Thomas Heller74d36f02006-08-04 18:17:40 +000049- On Windows, the PyErr_Warn function is now exported from
50 the Python dll again.
51
Neal Norwitz4ffedad2006-08-04 04:58:47 +000052- Bug #1191458: tracing over for loops now produces a line event
53 on each iteration. Fixing this problem required changing the .pyc
54 magic number. This means that .pyc files generated before 2.5c1
55 will be regenerated.
56
Neal Norwitz0cbd8052006-08-04 05:09:28 +000057- Bug #1333982: string/number constants were inappropriately stored
58 in the byte code and co_consts even if they were not used, ie
59 immediately popped off the stack.
60
Georg Brandle9462c72006-08-04 18:03:37 +000061- Fixed a reference-counting problem in property().
62
Neal Norwitzff4b63b2006-08-04 04:50:21 +000063
64Library
65-------
66
Georg Brandl0a7d1bb2006-08-11 07:26:10 +000067- logging's atexit hook now runs even if the rest of the module has
68 already been cleaned up.
69
Guido van Rossum133f4e42006-08-10 17:42:50 +000070- Bug #1112549, DoS attack on cgi.FieldStorage.
71
Neal Norwitzff4b63b2006-08-04 04:50:21 +000072- Bug #1531405, format_exception no longer raises an exception if
73 str(exception) raised an exception.
74
Neil Schemenauer06ded092006-08-04 16:20:30 +000075- Fix a bug in the ``compiler`` package that caused invalid code to be
76 generated for nested functions.
77
Neal Norwitzff4b63b2006-08-04 04:50:21 +000078
79Extension Modules
80-----------------
81
Georg Brandl3335a7a2006-08-14 21:42:55 +000082- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
83 raises the correct exceptions.
84
Thomas Heller1ce433e2006-08-14 16:20:04 +000085- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
86 '-no-stack-protector' compiler flag for OpenBSD has been removed.
87
Thomas Heller86720042006-08-14 11:17:48 +000088- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
89 uses the _as_parameter_ attribute when objects are passed to foreign
90 function calls. The ctypes version number was changed to 1.0.1.
91
Bob Ippolitoe6c9f982006-08-04 23:59:21 +000092- Bug #1530559, struct.pack raises TypeError where it used to convert.
93 Passing float arguments to struct.pack when integers are expected
94 now triggers a DeprecationWarning.
95
Neal Norwitzff4b63b2006-08-04 04:50:21 +000096
97Tests
98-----
99
Neal Norwitz003c9e22006-08-11 06:09:41 +0000100- test_mailbox should now work on cygwin versions 2006-08-10 and later.
101
Georg Brandl9908d162006-08-06 07:06:33 +0000102- Bug #1535182: really test the xreadlines() method of bz2 objects.
103
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000104- test_threading now skips testing alternate thread stack sizes on
105 platforms that don't support changing thread stack size.
106
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000107
Georg Brandl212b5872006-08-05 06:10:54 +0000108Documentation

126
Tim Peters4643c2f2006-08-10 22:45:34 +0000127- Bug #1069160. Internal correctness changes were made to
128 ``PyThreadState_SetAsyncExc()``. A test case was added, and
129 the documentation was changed to state that the return value
130 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000137What's New in Python 2.5 beta 3?
138================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000139
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000140*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000141
142Core and builtins
143-----------------
144
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000145- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
146 returned a long (see PEP 353).
147
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000148- Bug #1515471: string.replace() accepts character buffers again.
149
Neal Norwitz07aadb12006-07-30 06:55:48 +0000150- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
151 This provides the proper warning for struct.pack().
152 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
153
Neal Norwitz0d62a062006-07-30 06:53:31 +0000154- Patch #1531113: Fix augmented assignment with yield expressions.
155 Also fix a SystemError when trying to assign to yield expressions.
156
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000157- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
158 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
159 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
160 excessive filesystem operations during imports.
161
Tim Petersbc24eee2006-07-27 01:14:53 +0000162- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
163 operations on signed longs that are formally undefined by C.
164 Unfortunately, at least one compiler now cares about that, so complicated
165 the code to make that compiler happy again.
166
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000167- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
168
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000169- Patch #1232023: Stop including current directory in search
170 path on Windows.
171
Neal Norwitze1fdb322006-07-21 05:32:28 +0000172- Fix some potential crashes found with failmalloc.
173
Neal Norwitze7563102006-07-17 01:00:16 +0000174- Fix warnings reported by Klocwork's static analysis tool.
175
Neal Norwitz84be93b2006-07-16 01:50:38 +0000176- Bug #1512814, Fix incorrect lineno's when code within a function
177 had more than 255 blank lines.
178
Georg Brandl9dceedb2006-07-12 15:31:17 +0000179- Patch #1521179: Python now accepts the standard options ``--help`` and
180 ``--version`` as well as ``/?`` on Windows.
181
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000182- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000183 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000184 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000185
Tim Peters112aad32006-07-19 00:03:19 +0000186- Bug #1524317: Compiling Python ``--without-threads`` failed.
187 The Python core compiles again then, and, in a build without threads, the
188 new ``sys._current_frames()`` returns a dictionary with one entry,
189 mapping the faux "thread id" 0 to the current frame.
190
Ronald Oussoren3075e162006-07-25 20:28:55 +0000191- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000192
Ronald Oussoren3075e162006-07-25 20:28:55 +0000193
Neal Norwitza1f10902006-07-12 07:28:29 +0000194Library
195-------
196
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000197- Correction of patch #1455898: In the mbcs decoder, set final=False
198 for stream decoder, but final=True for the decode function.
199
Georg Brandl07fec3a2006-08-01 18:49:24 +0000200- os.urandom no longer masks unrelated exceptions like SystemExit or
201 KeyboardInterrupt.
202
Tim Peters4643c2f2006-08-10 22:45:34 +0000203- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000204 shutil.copytree on Windows
205
Georg Brandle34ac7c2006-07-30 11:07:23 +0000206- Bug #1002398: The documentation for os.path.sameopenfile now correctly
207 refers to file descriptors, not file objects.
208
Fred Drakefbdeaad2006-07-29 16:56:15 +0000209- Rename of the xml package to xmlcore, and the import hackery done to
210 make it appear at both names, has been removed. Bug #1511497,
211 #1513611, and probably others.
212
Georg Brandledd9b0d2006-07-29 09:33:26 +0000213- Bug #1441397: The compiler module now recognizes module and function
214 docstrings correctly as it did in Python 2.4.
215
Tim Peters6f681472006-07-27 23:44:37 +0000216- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
217 lost that tests are sorted by name before being run. This rarely
218 matters for well-written tests, but can create baffling symptoms if
219 side effects from one test to the next affect outcomes. ``DocTestFinder``
220 has been changed to sort the list of tests it returns.
221
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000222- The distutils version has been changed to 2.5.0, and are now kept
223 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000224
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000225- Bug #978833: Really close underlying socket in _socketobject.close.
226
Georg Brandl0619a322006-07-26 07:40:17 +0000227- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
228 with title().
229
Georg Brandlcf0c1722006-07-26 07:23:32 +0000230- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
231 to recursive calls and call it with the failing package name.
232
Martin v. Löwis0b483032006-07-25 09:53:12 +0000233- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
234
Georg Brandlc13c34c2006-07-24 14:09:56 +0000235- Patch #1515343: Fix printing of deprecated string exceptions with a
236 value in the traceback module.
237
Greg Ward48fae7a2006-07-23 16:05:51 +0000238- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
239
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000240- Patch #1524429: Use repr() instead of backticks in Tkinter again.
241
Brett Cannoncaebe222006-07-18 04:41:36 +0000242- Bug #1520914: Change time.strftime() to accept a zero for any position in its
243 argument tuple. For arguments where zero is illegal, the value is forced to
244 the minimum value that is correct. This is to support an undocumented but
245 common way people used to fill in inconsequential information in the time
246 tuple pre-2.4.
247
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000248- Patch #1220874: Update the binhex module for Mach-O.
249
Barry Warsawb110bad2006-07-21 14:51:07 +0000250- The email package has improved RFC 2231 support, specifically for
251 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
252 (name*0=<blah>) parameter continuations. This may change the types of
253 values returned from email.message.Message.get_param() and friends.
254 Specifically in some cases where non-encoded continuations were used,
255 get_param() used to return a 3-tuple of (None, None, string) whereas now it
256 will just return the string (since non-encoded continuations don't have
257 charset and language parts).
258
259 Also, whereas % values were decoded in all parameter continuations, they are
260 now only decoded in encoded parameter parts.
261
Ronald Oussoren3075e162006-07-25 20:28:55 +0000262- Bug #1517990: IDLE keybindings on MacOS X now work correctly
263
264- Bug #1517996: IDLE now longer shows the default Tk menu when a
265 path browser, class browser or debugger is the frontmost window on MacOS X
266
Barry Warsaw00decd72006-07-27 23:43:15 +0000267- Patch #1520294: Support for getset and member descriptors in types.py,
268 inspect.py, and pydoc.py. Specifically, this allows for querying the type
269 of an object against these built-in types and more importantly, for getting
270 their docstrings printed in the interactive interpreter's help() function.
271
Ronald Oussoren3075e162006-07-25 20:28:55 +0000272
Neal Norwitza1f10902006-07-12 07:28:29 +0000273Extension Modules
274-----------------
275
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000276- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
277 a socket operation on a socket with a timeout, the exception will be
278 caught correctly. Previously, the exception was not caught.
279
Thomas Heller1393d6a2006-07-28 21:43:20 +0000280- Patch #1529514: The _ctypes extension is now compiled on more
281 openbsd target platforms.
282
Tim Peters9cab5932006-07-28 00:30:00 +0000283- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
284 a memory leak, affecting pickles and deep copies.
285
Tim Petersbc24eee2006-07-27 01:14:53 +0000286- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000287 Paul Eggert.
288
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000289- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
290
Thomas Hellerce049a02006-07-14 17:51:14 +0000291- Patch #1521817: Index range checking on ctypes arrays containing
292 exactly one element enabled again. This allows iterating over these
293 arrays, without the need to check the array size before.
294
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000295- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000296 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000297 /dev/null in certain cases; this is now fixed.
298
Thomas Heller47d7a062006-07-12 08:43:47 +0000299- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
300 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000301
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000302- Because of a misspelled preprocessor symbol, ctypes was always
303 compiled without thread support; this is now fixed.
304
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000305- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
306 methods now allow their database parameter to be None as the
307 sleepycat API allows.
308
Matt Flemingec926502006-07-28 11:27:27 +0000309- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
310 bluetooth API compared with Linux and FreeBSD.
311
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000312Tests
313-----
314
315- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
316 how long the test file should take to play. Now accepts taking 2.93 secs
317 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
318
Georg Brandl4793aa32006-07-28 18:31:39 +0000319- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
320 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
321 run via ``regrtest.py``. Now they do.

330
331- PythonLauncher now works correctly when the path to the script contains
332 characters that are treated specially by the shell (such as quotes).
333
334- Bug #1527397: PythonLauncher now launches scripts with the working directory
335 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000336 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000337 expect.

345Core and builtins
346-----------------
347
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000348- Bug #1441486: The literal representation of -(sys.maxint - 1)
349 again evaluates to a int object, not a long.
350
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000351- Bug #1501934: The scope of global variables that are locally assigned
352 using augmented assignment is now correctly determined.
353
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000354- Bug #927248: Recursive method-wrapper objects can now safely
355 be released.
356
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000357- Bug #1417699: Reject locale-specific decimal point in float()
358 and atof().
359
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000360- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
361 omit a default "error" argument for NULL pointer. This allows
362 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000363
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000364- Bug #1519018: 'as' is now validated properly in import statements.
365
Neal Norwitz28746ab2006-07-09 22:14:42 +0000366- On 64 bit systems, int literals that use less than 64 bits are
367 now ints rather than longs.
368
Neal Norwitzed657552006-07-10 00:04:44 +0000369- Bug #1512814, Fix incorrect lineno's when code at module scope
370 started after line 256.
371
Tim Peters32a83612006-07-10 21:08:24 +0000372- New function ``sys._current_frames()`` returns a dict mapping thread
373 id to topmost thread stack frame. This is for expert use, and is
374 especially useful for debugging application deadlocks. The functionality
375 was previously available in Fazal Majid's ``threadframe`` extension
376 module, but it wasn't possible to do this in a wholly threadsafe way from
377 an extension.

386
Tim Peters32a83612006-07-10 21:08:24 +0000387- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000388 environment variable to be set in order to the SDK environment
389 for finding the compiler, include files, etc.

394
Thomas Woutersadd19112006-07-05 11:03:49 +0000395- string.Template() now correctly handles tuple-values. Previously,
396 multi-value tuples would raise an exception and single-value tuples would
397 be treated as the value they contain, instead.
398
Martin v. Löwisede77f52006-07-03 13:01:35 +0000399- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
400 even if some data are received.

406 degrees and radians.
407
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000408- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000409 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000410
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000411- Bug #1514703: Only setup canvas window in turtle when the canvas
412 is created.
413
Martin v. Löwis7596e832006-07-01 15:33:37 +0000414- Bug #1513223: .close() of a _socketobj now releases the underlying
415 socket again, which then gets closed as it becomes unreferenced.
416
Fred Drake10497c82006-06-29 02:57:48 +0000417- Bug #1504333: Make sgmllib support angle brackets in quoted
418 attribute values.
419
420- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
421 sgmllib ('[' and ']' were not accepted).
422
Georg Brandl1be63af2006-06-28 20:23:25 +0000423- Fix a bug in the turtle module's end_fill function.
424
Brett Cannon53ab5b72006-06-22 16:49:14 +0000425- Bug #1510580: The 'warnings' module improperly required that a Warning
426 category be either a types.ClassType and a subclass of Warning. The proper
427 check is just that it is a subclass with Warning as the documentation states.
428
Georg Brandlad29e632006-06-21 17:45:17 +0000429- The compiler module now correctly compiles the new try-except-finally
430 statement (bug #1509132).
431
Neal Norwitz60373cd2006-06-22 06:30:50 +0000432- The wsgiref package is now installed properly on Unix.
433
Vinay Sajip28e57612006-07-01 10:45:20 +0000434- A bug was fixed in logging.config.fileConfig() which caused a crash on
435 shutdown when fileConfig() was called multiple times.
436
Gerhard Häring762fbd32006-07-02 17:48:30 +0000437- The sqlite3 module did cut off data from the SQLite database at the first
438 null character before sending it to a custom converter. This has been fixed
439 now.
440
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000441Extension Modules
442-----------------
443
Tim Peters112aad32006-07-19 00:03:19 +0000444- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
445 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
446 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000447
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000448- Assigning None to pointer type fields in ctypes structures possible
449 overwrote the wrong fields, this is fixed now.
450
451- Fixed a segfault in _ctypes when ctypes.wintypes were imported
452 on non-Windows platforms.
453
454- Bug #1518190: The ctypes.c_void_p constructor now accepts any
455 integer or long, without range checking.
456
457- Patch #1517790: It is now possible to use custom objects in the ctypes
458 foreign function argtypes sequence as long as they provide a from_param
459 method, no longer is it required that the object is a ctypes type.
460
461- The '_ctypes' extension module now works when Python is configured
462 with the --without-threads option.
463
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000464- Bug #1513646: os.access on Windows now correctly determines write
465 access, again.
466
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000467- Bug #1512695: cPickle.loads could crash if it was interrupted with
468 a KeyboardInterrupt.
469
Neal Norwitza12aa882006-07-06 06:45:08 +0000470- Bug #1296433: parsing XML with a non-default encoding and
471 a CharacterDataHandler could crash the interpreter in pyexpat.

476-----
477
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000478- Automate Windows build process for the Win64 SSL module.
479
Tim Peters32a83612006-07-10 21:08:24 +0000480- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000481 Previously, the slight difference could cause compilation errors of the
482 'zlib' module on systems with more than one version of zlib.
483
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000484- The MSI compileall step was fixed to also support a TARGETDIR
485 with spaces in it.
486
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000487- Bug #1517388: sqlite3.dll is now installed on Windows independent
488 of Tcl/Tk.
489
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000490- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000491 trying to be installed even though it's empty.

500-------------
501
Nick Coghlan2d792252006-07-06 13:47:18 +0000502- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
503 documentation for the warnings module.
504
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000505- Patch #1509163: MS Toolkit Compiler no longer available.

515Core and builtins
516-----------------
517
Georg Brandla56b9152006-06-19 06:35:54 +0000518- Patch #1507676: Error messages returned by invalid abstract object operations
519 (such as iterating over an integer) have been improved and now include the
520 type of the offending object to help with debugging.
521
Brett Cannonea3912b2006-06-13 21:46:41 +0000522- Bug #992017: A classic class that defined a __coerce__() method that returned
523 its arguments swapped would infinitely recurse and segfault the interpreter.
524
Neal Norwitz909eb122006-06-12 02:13:21 +0000525- Fix the socket tests so they can be run concurrently.
526
Neal Norwitzb9845e72006-06-12 02:11:18 +0000527- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000528 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000529
Brett Cannon22565aa2006-06-09 22:31:23 +0000530- Bug #532646: object.__call__() will continue looking for the __call__
531 attribute on objects until one without one is found. This leads to recursion
532 when you take a class and set its __call__ attribute to an instance of the
533 class. Originally fixed for classic classes, but this fix is for new-style.
534 Removes the infinite_rec_3 crasher.
535
Georg Brandl24250812006-06-09 18:45:48 +0000536- The string and unicode methods startswith() and endswith() now accept
537 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
538
Brett Cannonde3b0522006-06-08 17:00:45 +0000539- Buffer objects, at the C level, never used the char buffer
540 implementation even when the char buffer for the wrapped object was
541 explicitly requested (originally returned the read or write buffer).
542 Now a TypeError is raised if the char buffer is not present but is
543 requested.
544
Georg Brandlddbaa662006-06-04 21:56:52 +0000545- Patch #1346214: Statements like "if 0: suite" are now again optimized
546 away like they were in Python 2.4.
547
Georg Brandlb7c8f542006-05-27 12:30:25 +0000548- Builtin exceptions are now full-blown new-style classes instead of
549 instances pretending to be classes, which speeds up exception handling
550 by about 80% in comparison to 2.5a2.
551
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000552- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
553 Unicode 4.1.
554
Georg Brandlf4ef1162006-05-26 18:03:31 +0000555- Patch #921466: sys.path_importer_cache is now used to cache valid and
556 invalid file paths for the built-in import machinery which leads to
557 fewer open calls on startup.
558
Tim Peters696cf432006-05-24 21:10:40 +0000559- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
560 of-2 bases. The largest speedup is for inputs with about 1000 decimal
561 digits. Conversion from non-power-of-2 bases remains quadratic-time in
562 the number of input digits (it was and remains linear-time for bases
563 2, 4, 8, 16 and 32).
564
Tim Petersb713ec22006-05-23 18:45:30 +0000565- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
566 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
567 an integer close to ``sys.maxint``. This was repaired by patch
568 #1335972, which also gives a nice speedup.
569
Richard Jonescebbefc2006-05-23 18:28:17 +0000570- Patch #1337051: reduced size of frame objects.
571
572- PyErr_NewException now accepts a tuple of base classes as its
573 "base" parameter.
574
Richard Jones7c88dcc2006-05-23 10:37:38 +0000575- Patch #876206: function call speedup by retaining allocated frame
576 objects.
577
Georg Brandl7b90e162006-05-18 07:01:27 +0000578- Bug #1462152: file() now checks more thoroughly for invalid mode
579 strings and removes a possible "U" before passing the mode to the
580 C library function.
581
Neal Norwitz1004a532006-05-15 07:17:23 +0000582- Patch #1488312, Fix memory alignment problem on SPARC in unicode
583
Neal Norwitz373f0a72006-05-15 07:04:36 +0000584- Bug #1487966: Fix SystemError with conditional expression in assignment
585
Martin v. Löwis879768d2006-05-11 13:28:43 +0000586- WindowsError now has two error code attributes: errno, which carries
587 the error values from errno.h, and winerror, which carries the error
588 values from winerror.h. Previous versions put the winerror.h values
589 (from GetLastError()) into the errno attribute.
590
Martin v. Löwis77736712006-05-04 05:51:03 +0000591- Patch #1475845: Raise IndentationError for unexpected indent.
592
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000593- Patch #1479181: split open() and file() from being aliases for each other.
594
Tim Peters44bd9862006-06-01 13:49:23 +0000595- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
596 methods were always silently ignored by dictionaries when comparing keys.
597 They are now passed through (except when using the C API function
598 ``PyDict_GetItem()``, whose semantics did not change).
599
600- Bug #1456209: In some obscure cases it was possible for a class with a
601 custom ``__eq__()`` method to confuse dict internals when class instances
602 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
603 No, you don't have any code that did this ;-)

609
610- Patch #1462338: Upgrade pyexpat to expat 2.0.0
611
Brett Cannon6ee7d012006-06-08 16:23:04 +0000612- Change binascii.hexlify to accept a read-only buffer instead of only a char
613 buffer and actually follow its documentation.
614

616
Nick Coghlanc649ec52006-05-29 12:43:05 +0000617- Patch #1478788 (modified version): The functional extension module has
618 been renamed to _functools and a functools Python wrapper module added.
619 This provides a home for additional function related utilities that are
620 not specifically about functional programming. See PEP 309.
621
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000622- Patch #1493701: performance enhancements for struct module.

Andrew MacIntyre92913322006-06-13 15:04:24 +0000629- Patch #1454481: thread stack size is now tunable at runtime for thread
630 enabled builds on Windows and systems with Posix threads support.
631
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000632- On Win32, os.listdir now supports arbitrarily-long Unicode path names
633 (up to the system limit of 32K characters).
634
635- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
636 As a result, these functions now raise WindowsError instead of OSError.
637
Tim Peters7a822da2006-05-25 21:50:17 +0000638- ``time.clock()`` on Win64 should use the high-performance Windows
639 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
640 Windows platforms).
641
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000642- Calling Tk_Init twice is refused if the first call failed as that
643 may deadlock.
644
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000645- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
646 accept it without potentially using an uninitialized pointer.
647
648- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
649 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +0000652- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000653 [pybsddb project SF patch number 1466734]
654
Gregory P. Smith372b5832006-06-05 18:48:21 +0000655- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
656 parameter is supplied. [SF pybsddb bug #1477863]
657
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000658- bsddb: the __len__ method of a DB object has been fixed to return correct
659 results. It could previously incorrectly return 0 in some cases.
660 Fixes SF bug 1493322 (pybsddb bug 1184012).
661
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000662- bsddb: the bsddb.dbtables Modify method now raises the proper error and
663 aborts the db transaction safely when a modifier callback fails.
664 Fixes SF python patch/bug #1408584.
665
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000666- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000667 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000668 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
669 database calls that would previously deadlock. [SF python bug #775414]

697
Martin v. Löwisd8251432006-06-14 05:21:04 +0000698- Patch #1455898: The MBCS codec now supports the incremental mode for
699 double-byte encodings.
700
Tim Peters43898b42006-06-14 04:09:25 +0000701- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
702 guarantee that adjacent triples in the return list always describe
703 non-adjacent blocks. Previously, a pair of matching blocks could end
704 up being described by multiple adjacent triples that formed a partition
705 of the matching pair.
706
Greg Ward0e0c9f42006-06-11 16:24:11 +0000707- Bug #1498146: fix optparse to handle Unicode strings in option help,
708 description, and epilog.
709
Greg Wardd1c797e2006-06-11 14:42:41 +0000710- Bug #1366250: minor optparse documentation error.

713 clarify docs.
714
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000715- The wsgiref package has been added to the standard library.
716
Nick Coghlan676725d2006-06-08 13:54:49 +0000717- The functions update_wrapper() and wraps() have been added to the functools
718 module. These make it easier to copy relevant metadata from the original
719 function when writing wrapper functions.
720
Tim Petersd6a9eef2006-06-05 01:48:21 +0000721- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
722 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000723
Martin v. Löwis3f767792006-06-04 19:36:28 +0000724- Patch #1359618: Speed up charmap encoder by using a trie structure
725 for lookup.
726
Tim Petersd609b1a2006-06-02 23:22:51 +0000727- The functions in the ``pprint`` module now sort dictionaries by key
728 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
729 if and only if its display required more than one line, although that
730 wasn't documented. The new behavior increases predictability; e.g.,
731 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
732
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000733- Patch #1497027: try HTTP digest auth before basic auth in urllib2

737 default HTTP and HTTPS ports.
738
George Yoshidaf3c65de2006-05-28 16:39:09 +0000739- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
740
Bob Ippolito7298f272006-05-23 18:43:47 +0000741- Patch #1281707: speed up gzip.readline.
742
Georg Brandlb89316f2006-05-17 15:51:16 +0000743- Patch #1180296: Two new functions were added to the locale module:
744 format_string() to get the effect of "format % items" but locale-aware,
745 and currency() to format a monetary number with currency sign.
746
Georg Brandle3a25832006-05-17 14:56:04 +0000747- Patch #1486962: Several bugs in the turtle Tk demo module were fixed

751 tarfiles.
752
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000753- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
754 stdout arguments, making it possible to redirect input and output
755 for remote debugging.
756
757- Patch #1484695: Update the tarfile module to version 0.8. This fixes
758 a couple of issues, notably handling of long file names using the
759 GNU LONGNAME extension.
760
761- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
762 new flag when ``name`` is already the name of an option flag.
763
764- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
765 package.
766
767- Patch #1472854: make the rlcompleter.Completer class usable on non-
768 UNIX platforms.
769

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000803What's New in Python 2.5 alpha 2?

805
806*Release date: 27-APR-2006*
807
808Core and builtins
809-----------------
810
Thomas Heller1b046642006-04-18 18:51:06 +0000811- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
812 by converting these apis from macros into exported functions again:
813
814 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
815 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
816 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
817 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
818 PyRun_String Py_CompileString
819
Martin v. Löwis45294a92006-04-18 06:24:08 +0000820- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
821
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000822- All uses of PyStructSequence_InitType have been changed to initialize
823 the type objects only once, even if the interpreter is initialized
824 multiple times.
825
Neal Norwitz61546162006-04-14 05:20:28 +0000826- Bug #1454485, array.array('u') could crash the interpreter. This was
827 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
828 to unicode when it didn't make sense. 'u#' now requires a unicode string.
829
830- Py_UNICODE is unsigned. It was always documented as unsigned, but
831 due to a bug had a signed value in previous versions.
832
Tim Peters3a5e8b12006-04-11 01:44:07 +0000833- Patch #837242: ``id()`` of any Python object always gives a positive
834 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
835 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000836 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000837 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000838
Tim Peters3a5e8b12006-04-11 01:44:07 +0000839 def __hash__(self):
840 return id(self) # WRONG
841
842 because a hash result must be a (short) Python int but it was always
843 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000844 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000845 was always usable as a hash value before this patch. That's no longer
846 necessarily so.
847
848- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000849 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000850 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000851 #1454844)
852
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000853- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
854 involving generators that have paused outside of any ``try`` or ``with``
855 blocks. (In 2.5a1, a paused generator that was part of a reference
856 cycle could not be garbage collected, regardless of whether it was
857 paused in a ``try`` or ``with`` block.)

876- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
877 as older versions cause excessive test failures.

883-------
884
Peter Astrand7d1d4362006-07-14 14:04:45 +0000885- Bug #1223937: subprocess.CalledProcessError reports the exit status
886 of the process using the returncode attribute, instead of
887 abusing errno.
888
Tim Peters711bf302006-04-25 03:31:36 +0000889- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
890 a doctest to be skipped (the code is not run, and the expected output
891 or exception is ignored).
892
Nick Coghlanda2268f2006-04-24 04:37:15 +0000893- Fixed contextlib.nested to cope with exceptions being raised and
894 caught inside exit handlers.
895
Greg Wardab05edc2006-04-23 03:47:58 +0000896- Updated optparse module to Optik 1.5.1 (allow numeric constants in
897 hex, octal, or binary; add ``append_const`` action; keep going if
898 gettext cannot be imported; added ``OptionParser.destroy()`` method;
899 added ``epilog`` for better help generation).
900
Tim Peters21fbd572006-04-21 21:18:10 +0000901- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
902 called from a thread spawned as a side effect of importing a module.
903
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000904- The pydoc module now supports documenting packages contained in
905 .zip or .egg files.
906
907- The pkgutil module now has several new utility functions, such
908 as ``walk_packages()`` to support working with packages that are either
909 in the filesystem or zip files.
910
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000911- The mailbox module can now modify and delete messages from
912 mailboxes, in addition to simply reading them. Thanks to Gregory
913 K. Johnson for writing the code, and to the 2005 Google Summer of
914 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000915
Tim Petersc7605f22006-04-17 21:12:33 +0000916- The ``__del__`` method of class ``local`` in module ``_threading_local``
917 returned before accomplishing any of its intended cleanup.
918

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000948- Patch #1470875: Building Python with MS Free Compiler
949
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000950- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000951
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000952- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
953 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000954 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000955 CXX from --with-cxx-main, see description in README.
956
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000957- Patch #1429775: Link extension modules with the shared libpython.
958
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000959- Fixed a libffi build problem on MIPS systems.
960
Tim Peters8931ff12006-05-13 23:28:20 +0000961- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
962 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
963 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000965Tests
966-----
967
Nick Coghlanda2268f2006-04-24 04:37:15 +0000968- test_contextlib now checks contextlib.nested can cope with exceptions
969 being raised and caught inside exit handlers.
970
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000971- test_cmd_line now checks operation of the -m and -c command switches
972
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000973- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
974 it separately and by hand. It also wasn't cleaning up its changes to
975 the current Decimal context.
976
Thomas Woutersabd08882006-04-26 15:53:30 +0000977- regrtest.py now has a -M option to run tests that test the new limits of
978 containers, on 64-bit architectures. Running these tests is only sensible
979 on 64-bit machines with more than two gigabytes of memory. The argument
980 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000988Documentation
989-------------
990
Tim Petersb06d28c2006-05-12 01:57:59 +0000991- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
992
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000993- PEP 343: Added Context Types section to the library reference
994 and attempted to bring other PEP 343 related documentation into
995 line with the implementation and/or python-dev discussions.
996
Tim Peters8dc73d22006-04-24 02:03:16 +0000997- Bug #1337990: clarified that ``doctest`` does not support examples
998 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001001What's New in Python 2.5 alpha 1?
1002=================================
1003
Anthony Baxterebed3f62006-04-03 15:03:44 +00001004*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001005
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001006Core and builtins
1007-----------------
1008
Nick Coghlan43832302006-04-23 17:04:07 +00001009- PEP 338: -m command line switch now delegates to runpy.run_module
1010 allowing it to support modules in packages and zipfiles
1011
Martin v. Löwisc661b882006-04-20 04:54:23 +00001012- On Windows, .DLL is not an accepted file name extension for
1013 extension modules anymore; extensions are only found if they
1014 end in .PYD.
1015
Martin v. Löwisea62d252006-04-03 10:56:49 +00001016- Bug #1421664: sys.stderr.encoding is now set to the same value as
1017 sys.stdout.encoding.
1018
Neal Norwitz92e212f2006-04-03 04:48:37 +00001019- __import__ accepts keyword arguments.
1020
Georg Brandlccadf842006-03-31 18:54:53 +00001021- Patch #1460496: round() now accepts keyword arguments.
1022
Anthony Baxter262c00a2006-03-30 10:53:17 +00001023- Fixed bug #1459029 - unicode reprs were double-escaped.
1024
Hye-Shik Changd478f342006-03-23 12:32:36 +00001025- Patch #1396919: The system scope threads are reenabled on FreeBSD
1026 5.4 and later versions.
1027
Neal Norwitze98ccf62006-03-23 05:39:47 +00001028- Bug #1115379: Compiling a Unicode string with an encoding declaration
1029 now gives a SyntaxError.
1030
Georg Brandlabd1ff82006-03-18 07:59:59 +00001031- Previously, Python code had no easy way to access the contents of a
1032 cell object. Now, a ``cell_contents`` attribute has been added
1033 (closes patch #1170323).
1034
Tim Peterscf79aac2006-03-16 01:14:46 +00001035- Patch #1123430: Python's small-object allocator now returns an arena to
1036 the system ``free()`` when all memory within an arena becomes unused
1037 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1038 freed. Some applications will see a drop in virtual memory size now,
1039 especially long-running applications that, from time to time, temporarily
1040 use a large number of small objects. Note that when Python returns an
1041 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001042 platform C library will in turn return that memory to the operating system.
1043 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001044 appears to be effective at least on Microsoft C and gcc-based systems.
1045 Thanks to Evan Jones for hard work and patience.
1046
Georg Brandl533ff6f2006-03-08 18:09:27 +00001047- Patch #1434038: property() now uses the getter's docstring if there is
1048 no "doc" argument given. This makes it possible to legitimately use
1049 property() as a decorator to produce a read-only property.
1050
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001051- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1052 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1053 of requiring an int or long in slicing and a few other contexts, enabling
1054 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1055
Neal Norwitz995acdf2006-03-07 05:01:00 +00001056- Fixed various bugs reported by Coverity's Prevent tool.
1057
Brett Cannonbf364092006-03-01 04:25:17 +00001058- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1059 new exception base class, BaseException, which has a new message attribute.
1060 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1061 Raising a string exception now raises a DeprecationWarning.
1062
Thomas Woutersfb609f42006-02-28 16:37:25 +00001063- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1064 explicitly relative, using 'from .module import name' to mean 'from the same
1065 package as this module is in. Imports without dots still default to the
1066 old relative-then-absolute, unless 'from __future__ import
1067 absolute_import' is used.
1068
Brett Cannona7446e32006-02-27 23:39:10 +00001069- Properly check if 'warnings' raises an exception (usually when a filter set
1070 to "error" is triggered) when raising a warning for raising string
1071 exceptions.
1072
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001073- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001074 The name was removed from Include/code.h.
1075
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001076- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001077
Guido van Rossum1968ad32006-02-25 22:38:04 +00001078- Patch 1433928:
1079 - The copy module now "copies" function objects (as atomic objects).
1080 - dict.__getitem__ now looks for a __missing__ hook before raising
1081 KeyError.
1082
Tim Peters84ef21c2006-02-28 20:39:06 +00001083- PEP 343: with statement implemented. Needs ``from __future__ import
1084 with_statement``. Use of 'with' as a variable will generate a warning.
1085 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001086 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001087 The following objects have __context__ methods:
1088 - The built-in file type.
1089 - The thread.LockType type.
1090 - The following types defined by the threading module:
1091 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1092 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001093
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001094- Fix the encodings package codec search function to only search
1095 inside its own package. Fixes problem reported in patch #1433198.
1096
1097 Note: Codec packages should implement and register their own
1098 codec search function. PEP 100 has the details.
1099
Tim Peters9ea89d22006-06-04 03:26:02 +00001100- PEP 353: Using ``Py_ssize_t`` as the index type.
1101
1102- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1103 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1104 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1105 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1106 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001107
Neal Norwitzfc76d632006-01-10 06:03:13 +00001108- Patch #1400181, fix unicode string formatting to not use the locale.
1109 This is how string objects work. u'%f' could use , instead of .
1110 for the decimal point. Now both strings and unicode always use periods.
1111
Neal Norwitz671b9e32006-01-09 07:07:12 +00001112- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1113 configure would break checking curses.h.
1114
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001115- Bug #959576: The pwd module is now builtin. This allows Python to be
1116 built on UNIX platforms without $HOME set.
1117
Neal Norwitzc10978f2005-12-19 06:07:16 +00001118- Bug #1072182, fix some potential problems if characters are signed.
1119
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001120- Bug #889500, fix line number on SyntaxWarning for global declarations.
1121
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001122- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1123
Neal Norwitze7214a12005-12-18 05:03:17 +00001124- Support for converting hex strings to floats no longer works.
1125 This was not portable. float('0x3') now raises a ValueError.
1126
Barry Warsaw2a38a862005-12-18 01:27:35 +00001127- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001128 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001129 is now displayed in interactive prompt banner.
1130
Georg Brandlfa166682005-12-17 21:45:17 +00001131- Implementation of PEP 341 - Unification of try/except and try/finally.
1132 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001133 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001134
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001135- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1136 now encodes backslash correctly.
1137
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001138- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1139
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001140- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001141 and long longs.
1142
Neal Norwitz67715f02005-11-09 06:59:35 +00001143- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001144 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001145 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001146
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001147- Replaced most Unicode charmap codecs with new ones using the
1148 new Unicode translate string feature in the builtin charmap
1149 codec; the codecs were created from the mapping tables available
1150 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1151 encodings now include a mapping for the Apple logo)
1152
Tim Peterse3547fd2005-12-16 23:13:57 +00001153- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001154
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001155- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001156
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001157- A new AST parser implementation was completed. The abstract
1158 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001159 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001160
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001161- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001162 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1163
Neal Norwitz708e51a2005-10-03 04:48:15 +00001164- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1165
Neal Norwitz11bd1192005-10-03 00:54:56 +00001166- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1167 Provide a warning when a directory is passed on the command line.
1168
Neal Norwitz40d37812005-10-02 01:48:49 +00001169- Fix segfault with invalid coding.
1170
1171- SF bug #772896: unknown encoding results in MemoryError.
1172
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001173- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001174 supported a __len__() method which evaluated to False when the iterator
1175 was empty.
1176
Guido van Rossum630db602005-09-20 18:49:54 +00001177- On 64-bit platforms, when __len__() returns a value that cannot be
1178 represented as a C int, raise OverflowError.
1179
Skip Montanarof8948ca2005-09-19 03:54:46 +00001180- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001181 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001182
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001183- SF bug #893549: parsing keyword arguments was broken with a few format
1184 codes.
1185
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001186- Changes donated by Elemental Security to make it work on AIX 5.3
1187 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1188 bug #105470: test_pwd fails on 64bit system (Opteron).
1189
Guido van Rossum539c6622005-09-14 17:49:54 +00001190- Changes donated by Elemental Security to make it work on HP-UX 11 on
1191 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1192
Georg Brandl4550b8d2005-08-26 06:43:52 +00001193- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001194 (fixes bug #1119418).
1195
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001196- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1197
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001198- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1199 exceptions that cause a function to exit.
1200
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001201- The implementation of set() and frozenset() was revised to use its
1202 own internal data structure. Memory consumption is reduced by 1/3
1203 and there are modest speed-ups as well. The API is unchanged.
1204
Tim Petersde7990b2005-07-17 23:45:23 +00001205- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1206
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001207- SF bug #1229429: PyObject_CallMethod failed to decrement some
1208 reference counts in some error exit cases.
1209
Tim Petersecc6e6a2005-07-10 22:30:55 +00001210- SF bug #1185883: Python's small-object memory allocator took over
1211 a block managed by the platform C library whenever a realloc specified
1212 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001213 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001214 portable way to copy data from the C-managed block into Python's
1215 small-object space without risking a memory fault. Python's small-object
1216 realloc now leaves such blocks under the control of the platform C
1217 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00001219- SF bug #1232517: An overflow error was not detected properly when
1220 attempting to convert a large float to an int in os.utime().
1221
Raymond Hettinger3296e692005-06-29 23:29:56 +00001222- SF bug #1224347: hex longs now print with lowercase letters just
1223 like their int counterparts.
1224
Michael W. Hudson188d4362005-06-20 16:52:57 +00001225- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1226 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1227 interpreter states; back out that fix and do a better job (see
1228 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1229 for a longer write-up of the problem).
1230
Michael W. Hudsondf888462005-06-03 14:41:55 +00001231- SF patch #1180995: marshal now uses a binary format by default when
1232 serializing floats.
1233
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001234- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1235 the routines that promise to produce IEEE 754 binary representations
1236 of floats now simply copy bytes around.
1237
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001238- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1239 278.
1240
Brett Cannonc3647ac2005-04-26 03:45:26 +00001241- patch #1109424: int, long, float, complex, and unicode now check for the
1242 proper magic slot for type conversions when subclassed. Previously the
1243 magic slot was ignored during conversion. Semantics now match the way
1244 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001245 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001246 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001247 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001248
Barry Warsawc8d907c2005-04-19 23:43:40 +00001249- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1250 NULL, now raise an AttributeError when attempting to set or delete the
1251 attribute. Previously a TypeError was raised, but this was inconsistent
1252 with the equivalent pure-Python implementation.
1253
Michael W. Hudson774479c2005-04-18 08:46:17 +00001254- It is now safe to call PyGILState_Release() before
1255 PyEval_InitThreads() (note that if there is reason to believe there
1256 are multiple threads around you still must call PyEval_InitThreads()
1257 before using the Python API; this fix is for extension modules that
1258 have no way of knowing if Python is multi-threaded yet).
1259
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001260- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1261 disabled caused a crash.
1262
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001263- Bug #1165306: instancemethod_new allowed the creation of a method
1264 with im_class == im_self == NULL, which caused a crash when called.
1265
Tim Petersecc6e6a2005-07-10 22:30:55 +00001266- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001267 fixes the crash seen in bug #1165761
1268
Raymond Hettinger96229b12005-03-11 06:49:40 +00001269- Added two new builtins, any() and all().
1270
Brett Cannon409d8f22005-03-05 06:47:57 +00001271- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001272 (e.g., ``class C(): pass`` is no longer a syntax error).
1273 Patch #1176012 added support to the 'parser' module and 'compiler' package
1274 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001275
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001276- Patch #1115086: Support PY_LONGLONG in structmember.
1277
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001278- Bug #1155938: new style classes did not check that __init__() was
1279 returning None.
1280
Tim Petersecc6e6a2005-07-10 22:30:55 +00001281- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001282 ('\') with a specific error message.
1283
Martin v. Löwisff232d72005-03-03 09:24:38 +00001284- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1285
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001286- Bug #1124295: the __name__ attribute of file objects was
1287 inadvertently made inaccessible in restricted mode.
1288
Tim Petersecc6e6a2005-07-10 22:30:55 +00001289- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001290 an ferror() call.
1291
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001292- min() and max() now support key= arguments with the same meaning as in
1293 list.sort().
1294
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001295- The peephole optimizer now performs simple constant folding in expressions:
1296 (2+3) --> (5).
1297
Raymond Hettingera422c342005-01-11 03:03:27 +00001298- set and frozenset objects can now be marshalled. SF #1098985.
1299
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001300- Bug #1077106: Poor argument checking could cause memory corruption
1301 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001302
Jeremy Hyltonab630502005-02-04 18:44:06 +00001303- The parser did not complain about future statements in illegal
1304 positions. It once again reports a syntax error if a future
1305 statement occurs after anything other than a doc string.
1306
Neil Schemenauercf52c072005-08-12 17:34:58 +00001307- Change the %s format specifier for str objects so that it returns a
1308 unicode instance if the argument is not an instance of basestring and
1309 calling __str__ on the argument returns a unicode instance.
1310
Tim Petersf4e69282006-02-27 17:15:31 +00001311- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1312 current thread state when the auto-GIL-state machinery knows about
1313 it (since the thread state is being deleted, continuing to remember it
1314 can't help, but can hurt if another thread happens to get created with
1315 the same thread id).
1316
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001317Extension Modules

1334
1335- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1336
1337- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001338 is deprecated. The undocumented re.engine variable no longer exists.

1342
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001343- The unicodedata module was updated to the 4.1 version of the Unicode
1344 database. The 3.2 version is still available as unicodedata.db_3_2_0
1345 for applications that require this specific version (such as IDNA).
1346
Neal Norwitzb62c4332006-03-04 18:35:47 +00001347- The timing module is no longer built by default. It was deprecated

Martin v. Löwis14694662006-02-03 12:54:16 +00001369- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1370 are reported, the limit on path name lengths is removed, and stat reports
1371 WindowsError now (instead of OSError).
1372

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001491- the cPickle module no longer accepts the deprecated None option in the
1492 args tuple returned by __reduce__().
1493
Raymond Hettingerb2594052004-12-05 09:25:51 +00001494- itertools.islice() now accepts None for the start and step arguments.
1495 This allows islice() to work more readily with slices:
1496 islice(s.start, s.stop, s.step)
1497
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001498- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001507- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1508 been renamed to have only a single underscore prefix. This was done to
1509 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001510
Nick Coghlan43832302006-04-23 17:04:07 +00001511- PEP 338: new module runpy defines a run_module function to support
1512 executing modules which provide access to source code or a code object
1513 via the PEP 302 import mechanisms.
1514
Anthony Baxter93f5b932006-04-03 08:05:07 +00001515- The email module's parsedate_tz function now sets the daylight savings
1516 flag to -1 (unknown) since it can't tell from the date whether it should

1523 in attribute values.
1524
Anthony Baxterc51ee692006-04-01 00:57:31 +00001525- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001526 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001527 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001528 module will not be built.
1529
Tim Petersc17976e2006-04-01 00:26:53 +00001530- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1531 aren't officially supported here, and trying to use them will probably
1532 raise an exception some day. But dicts have been allowed, and "mostly
1533 worked", so support for them won't go away without warning.
1534
Georg Brandl338ef7d2006-03-31 18:42:16 +00001535- Bug #1445068: getpass.getpass() can now be given an explicit stream
1536 argument to specify where to write the prompt.
1537
Georg Brandl22ec80b2006-03-31 18:25:44 +00001538- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1547 to make it easier to monitor when daemon threads have completed
1548 processing all enqueued tasks. Patch #1455676.
1549
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001550- popen2.Popen objects now preserve the command in a .cmd attribute.

1553
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001554- email 4.0 package now integrated. This is largely the same as the email 3.0
1555 package that was included in Python 2.3, except that PEP 8 module names are
1556 now used (e.g. mail.message instead of email.Message). The MIME classes
1557 have been moved to a subpackage (e.g. email.mime.text instead of
1558 email.MIMEText). The old names are still supported for now. Several
1559 deprecated Message methods have been removed and lots of bugs have been
1560 fixed. More details can be found in the email package documentation.
1561
Walter Dörwald40108c92006-03-27 08:15:44 +00001562- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1563 (a subclass of tuple) that provides incremental decoders and encoders
1564 (a way to use stateful codecs without the stream API). Python functions
1565 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1566 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1567 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001568
Walter Dörwald067db482006-03-15 22:17:27 +00001569- Patch #1359365: Calling next() on a closed StringIO.String object raises
1570 a ValueError instead of a StopIteration now (like file and cString.String do).
1571 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1572 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001573
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001574- A regrtest option -w was added to re-run failed tests in verbose mode.

1647 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1648 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1649 Ronald L. Rivest offered this advice for Python:
1650
1651 "The consensus of researchers in this area (at least as
1652 expressed at the NIST Hash Function Workshop 10/31/05),
1653 is that SHA-256 is a good choice for the time being, but
1654 that research should continue, and other alternatives may
1655 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001656
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001657- Added a subset of Fredrik Lundh's ElementTree package. Available

1751
Raymond Hettinger68c04532005-06-10 11:05:19 +00001752- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001753 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001754 the generate_tokens() function now accepts a callable argument that
1755 terminates by raising StopIteration.

1761
Skip Montanaro174dd222005-05-14 20:54:16 +00001762- Patch #1120353: The xmlrpclib module provides better, more transparent,
1763 support for datetime.{datetime,date,time} objects. With use_datetime set
1764 to True, applications shouldn't have to fiddle with the DateTime wrapper
1765 class at all.
1766
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001767- distutils.commands.upload was added to support uploading distribution
1768 files to PyPI.
1769
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001770- distutils.commands.register now encodes the data as UTF-8 before posting
1771 them to PyPI.
1772
Raymond Hettinger267b8682005-03-27 10:47:39 +00001773- decimal operator and comparison methods now return NotImplemented
1774 instead of raising a TypeError when interacting with other types. This
1775 allows other classes to implement __radd__ style methods and have them
1776 work as expected.
1777
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001778- Bug #1163325: Decimal infinities failed to hash. Attempting to

1815
Guido van Rossumd0641422005-02-03 15:01:24 +00001816- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1817 disables recursive traversal through instance attributes, which can
1818 be exploited in various ways.
1819
Tim Peterse3547fd2005-12-16 23:13:57 +00001820- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001821 flags on the HTTP listening socket.
1822
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001823- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1824 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1825
Fred Drakefbdeaad2006-07-29 16:56:15 +00001826- Patches #893642, #1039083: add allow_none, encoding arguments to

1832
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001833- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1834
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001835- Enhancements to the csv module:
1836
1837 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001838 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001839 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001840 + Dialect parameter parsing has been re-implemented to improve error
1841 reporting.
1842 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1843 dictates.
1844 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001845 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001846 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001847 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1848 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001849 + reader now allows \r characters to be quoted (previously it only allowed
1850 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001851 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001852 + Dialect classes passed to the module are no longer instantiated by
1853 the module before being parsed (the former validation scheme required
1854 this, but the mechanism was unreliable).
1855 + The dialect registry now contains instances of the internal
1856 C-coded dialect type, rather than references to python objects.
1857 + the internal c-coded dialect type is now immutable.
1858 + register_dialect now accepts the same keyword dialect specifications
1859 as the reader and writer, allowing the user to register dialects
1860 without first creating a dialect class.
1861 + a configurable limit to the size of parsed fields has been added -
1862 previously, an unmatched quote character could result in the entire
1863 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001864 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001865 the parser field size limit (returning the former limit). The initial
1866 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001867 + A line_num attribute has been added to the reader object, which tracks
1868 the number of lines read from the source iterator. This is not
1869 the same as the number of records returned, as records can span
1870 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001871 + reader and writer objects were not being registered with the cyclic-GC.
1872 This has been fixed.
1873
Brett Cannone6539c42005-01-08 02:43:53 +00001874- _DummyThread objects in the threading module now delete self.__block that is
1875 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1876 lock primitives tend to be limited in number and thus should not be wasted on
1877 a _DummyThread object. Fixes bug #1089632.
1878
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001879- The imghdr module now detects Exif files.
1880
Raymond Hettinger6065d322004-12-20 23:51:53 +00001881- StringIO.truncate() now correctly adjusts the size attribute.
1882 (Bug #951915).
1883
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001884- locale.py now uses an updated locale alias table (built using
1885 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1886 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001887 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001888
Raymond Hettinger3557f422004-12-07 12:02:02 +00001889- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1890
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001891- the pickle module no longer accepts the deprecated None option in the
1892 args tuple returned by __reduce__().
1893
Brett Cannon84667c02004-12-07 03:25:18 +00001894- optparse now optionally imports gettext. This allows its use in setup.py.
1895
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001896- the pickle module no longer uses the deprecated bin parameter.
1897
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001898- the shelve module no longer uses the deprecated binary parameter.
1899
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001900- the pstats module no longer uses the deprecated ignore() method.
1901
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001902- the filecmp module no longer uses the deprecated use_statcache argument.
1903
Raymond Hettinger664347b2004-12-04 21:21:53 +00001904- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1905 extended or overridden by subclasses. Formerly, the subclassed method would
1906 be ignored by the rest of the module. (Bug #1078905).
1907
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001908- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001909 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001910
Walter Dörwald36733692004-12-22 12:50:50 +00001911- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1912 once when a size argument is given. This prevents a buffer overflow in the
1913 tokenizer with very long source lines.
1914
Barry Warsaw538561e2006-01-01 21:48:54 +00001915- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1916 immediately after creating the object, without any intervening
1917 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001918
Skip Montanaro05885812005-01-16 20:48:27 +00001919- The reconvert.quote function can now emit triple-quoted strings. The
1920 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001921
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001922- ``UserString.MutableString`` now supports negative indices in
1923 ``__setitem__`` and ``__delitem__``
1924
Greg Ward40407942005-03-05 02:53:17 +00001925- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1926 correctly.
1927
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001928- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1929 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1930 character even if the user has passed a size parameter to get a proper
1931 line ending. Remove the special handling of a "\r\n" that has been split
1932 between two lines.
1933
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001934- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1935 about illegal code points. The codec now supports PEP 293 style error
1936 handlers.
1937
Walter Dörwald78a78b02005-09-01 12:04:29 +00001938- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001939 from the input stream, so that the output is a byte string in the correct
1940 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001941
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001942- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1943 considering it exactly like a '*'.
1944
Walter Dörwald007f8df2005-10-09 19:42:27 +00001945- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1946 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001947
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001948- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1949
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001950- Patch #1413711: Certain patterns of differences were making difflib
1951 touch the recursion limit.
1952
Walter Dörwald58917a62006-03-31 15:26:22 +00001953- Bug #947906: An object oriented interface has been added to the calendar
1954 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001955 called as a script (e.g. via ``python -mcalendar``). Localized month and
1956 weekday names can be ouput (even if an exotic encoding is used) using
1957 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001958
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001959Build
1960-----
1961

1966
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001967- Build support for Win64-AMD64 was added.
1968
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001969- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1970
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001971- Patch #881820: look for openpty and forkpty also in libbsd.
1972
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001973- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1974 The zlib module is now builtin on Windows.
1975
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001976- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1977
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001978- Bug #1189330: configure did not correctly determine the necessary
1979 value of LINKCC if python was built with GCC 4.0.
1980
Trent Mick8321b422005-07-26 02:29:21 +00001981- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1982 vulnerability in zlib 1.2.1 and 1.2.2.
1983
Brett Cannon08cd5982005-04-24 22:26:38 +00001984- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1985 flags that change binary compatibility. Changes were also made to
1986 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001987 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001988
Bob Ippolitoed233462005-03-29 13:47:59 +00001989- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1990 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1991 no longer exists). This configure patch makes things right.
1992
Martin v. Löwise2713be2005-03-08 15:03:08 +00001993- Bug #1158607: Build with --disable-unicode again.
1994
Brett Cannon46d96232005-02-16 00:07:19 +00001995- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1996 defined. Discovered as a result of not being able to build on OS X.
1997
Brett Cannon516592f2004-12-07 00:42:59 +00001998- setup.py now uses the directories specified in LDFLAGS using the -L option
1999 and in CPPFLAGS using the -I option for adding library and include
2000 directories, respectively, for compiling extension modules against. This has
2001 led to the core being compiled using the values in CPPFLAGS. It also removes
2002 the need for the special-casing of both DarwinPorts and Fink for darwin since
2003 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2004 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2005 Fink, ``-I/opt/local/include`` for DarwinPorts).
2006
Brett Cannon43802422005-02-10 20:48:03 +00002007- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2008 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2009 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.

2014
Tim Petersc9d78aa2006-03-26 23:27:58 +00002015- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2016 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2017 is obtained via the ``PyObject_`` family, it must be released via the
2018 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2019 always been officially true, but when Python's small-object allocator was
2020 introduced, an attempt was made to cater to a few extension modules
2021 discovered at the time that obtained memory via ``PyObject_New`` but
2022 released it via ``PyMem_DEL``. It's years later, and if such code still
2023 exists it will fail now (probably with segfaults, but calling wrong
2024 low-level memory management functions can yield many symptoms).
2025
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002026- Added a C API for set and frozenset objects.

2029
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002030- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2031 mapping argument now. This string is used as a mapping table. Byte values
2032 greater than the length of the string and 0xFFFE are treated as undefined
2033 mappings.
