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
Martin v. Löwisab2f8f72006-08-09 07:57:39 +000028- Bug #1536021: __hash__ may now return long int; the final hash
29 value is obtained by invoking hash on the long int.
30
Thomas Hellerab1049c2006-08-08 17:37:00 +000031- Bug #1536786: buffer comparison could emit a RuntimeWarning.
32
Georg Brandl7e3ba2a2006-08-06 08:23:54 +000033- Bug #1535165: fixed a segfault in input() and raw_input() when
34 sys.stdin is closed.
35
Thomas Heller74d36f02006-08-04 18:17:40 +000036- On Windows, the PyErr_Warn function is now exported from
37 the Python dll again.
38
Neal Norwitz4ffedad2006-08-04 04:58:47 +000039- Bug #1191458: tracing over for loops now produces a line event
40 on each iteration. Fixing this problem required changing the .pyc
41 magic number. This means that .pyc files generated before 2.5c1
42 will be regenerated.
43
Neal Norwitz0cbd8052006-08-04 05:09:28 +000044- Bug #1333982: string/number constants were inappropriately stored
45 in the byte code and co_consts even if they were not used, ie
46 immediately popped off the stack.
47
Georg Brandle9462c72006-08-04 18:03:37 +000048- Fixed a reference-counting problem in property().
49
Neal Norwitzff4b63b2006-08-04 04:50:21 +000050
51Library
52-------
53
Georg Brandl0a7d1bb2006-08-11 07:26:10 +000054- logging's atexit hook now runs even if the rest of the module has
55 already been cleaned up.
56
Guido van Rossum133f4e42006-08-10 17:42:50 +000057- Bug #1112549, DoS attack on cgi.FieldStorage.
58
Neal Norwitzff4b63b2006-08-04 04:50:21 +000059- Bug #1531405, format_exception no longer raises an exception if
60 str(exception) raised an exception.
61
Neil Schemenauer06ded092006-08-04 16:20:30 +000062- Fix a bug in the ``compiler`` package that caused invalid code to be
63 generated for nested functions.
64
Neal Norwitzff4b63b2006-08-04 04:50:21 +000065
66Extension Modules
67-----------------
68
Thomas Heller86720042006-08-14 11:17:48 +000069- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
70 uses the _as_parameter_ attribute when objects are passed to foreign
71 function calls. The ctypes version number was changed to 1.0.1.
72
Bob Ippolitoe6c9f982006-08-04 23:59:21 +000073- Bug #1530559, struct.pack raises TypeError where it used to convert.
74 Passing float arguments to struct.pack when integers are expected
75 now triggers a DeprecationWarning.
76
Neal Norwitzff4b63b2006-08-04 04:50:21 +000077

82
Georg Brandl9908d162006-08-06 07:06:33 +000083- Bug #1535182: really test the xreadlines() method of bz2 objects.
84
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +000085- test_threading now skips testing alternate thread stack sizes on
86 platforms that don't support changing thread stack size.
87
Neal Norwitzff4b63b2006-08-04 04:50:21 +000088
Georg Brandl212b5872006-08-05 06:10:54 +000089Documentation
90-------------

96-----
97
Thomas Hellerdb7b4432006-08-04 19:49:31 +000098- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
99
Thomas Heller17984892006-08-04 18:57:34 +0000100- Bug #1530448, ctypes buld failure on Solaris 10 was fixed.
101
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000102
Tim Peters4643c2f2006-08-10 22:45:34 +0000103C API
104-----
105
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000106- New API for Unicode rich comparisons: PyUnicode_RichCompare()
107
Tim Peters4643c2f2006-08-10 22:45:34 +0000108- Bug #1069160. Internal correctness changes were made to
109 ``PyThreadState_SetAsyncExc()``. A test case was added, and
110 the documentation was changed to state that the return value
111 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000118What's New in Python 2.5 beta 3?
119================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000120
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000121*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000122
123Core and builtins
124-----------------
125
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000126- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
127 returned a long (see PEP 353).
128
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000129- Bug #1515471: string.replace() accepts character buffers again.
130
Neal Norwitz07aadb12006-07-30 06:55:48 +0000131- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
132 This provides the proper warning for struct.pack().
133 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
134
Neal Norwitz0d62a062006-07-30 06:53:31 +0000135- Patch #1531113: Fix augmented assignment with yield expressions.
136 Also fix a SystemError when trying to assign to yield expressions.
137
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000138- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
139 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
140 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
141 excessive filesystem operations during imports.
142
Tim Petersbc24eee2006-07-27 01:14:53 +0000143- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
144 operations on signed longs that are formally undefined by C.
145 Unfortunately, at least one compiler now cares about that, so complicated
146 the code to make that compiler happy again.
147
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000148- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
149
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000150- Patch #1232023: Stop including current directory in search
151 path on Windows.
152
Neal Norwitze1fdb322006-07-21 05:32:28 +0000153- Fix some potential crashes found with failmalloc.
154
Neal Norwitze7563102006-07-17 01:00:16 +0000155- Fix warnings reported by Klocwork's static analysis tool.
156
Neal Norwitz84be93b2006-07-16 01:50:38 +0000157- Bug #1512814, Fix incorrect lineno's when code within a function
158 had more than 255 blank lines.
159
Georg Brandl9dceedb2006-07-12 15:31:17 +0000160- Patch #1521179: Python now accepts the standard options ``--help`` and
161 ``--version`` as well as ``/?`` on Windows.
162
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000163- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000164 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000165 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000166
Tim Peters112aad32006-07-19 00:03:19 +0000167- Bug #1524317: Compiling Python ``--without-threads`` failed.
168 The Python core compiles again then, and, in a build without threads, the
169 new ``sys._current_frames()`` returns a dictionary with one entry,
170 mapping the faux "thread id" 0 to the current frame.
171
Ronald Oussoren3075e162006-07-25 20:28:55 +0000172- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000173
Ronald Oussoren3075e162006-07-25 20:28:55 +0000174
Neal Norwitza1f10902006-07-12 07:28:29 +0000175Library
176-------
177
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000178- Correction of patch #1455898: In the mbcs decoder, set final=False
179 for stream decoder, but final=True for the decode function.
180
Georg Brandl07fec3a2006-08-01 18:49:24 +0000181- os.urandom no longer masks unrelated exceptions like SystemExit or
182 KeyboardInterrupt.
183
Tim Peters4643c2f2006-08-10 22:45:34 +0000184- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000185 shutil.copytree on Windows
186
Georg Brandle34ac7c2006-07-30 11:07:23 +0000187- Bug #1002398: The documentation for os.path.sameopenfile now correctly
188 refers to file descriptors, not file objects.
189
Fred Drakefbdeaad2006-07-29 16:56:15 +0000190- Rename of the xml package to xmlcore, and the import hackery done to
191 make it appear at both names, has been removed. Bug #1511497,
192 #1513611, and probably others.
193
Georg Brandledd9b0d2006-07-29 09:33:26 +0000194- Bug #1441397: The compiler module now recognizes module and function
195 docstrings correctly as it did in Python 2.4.
196
Tim Peters6f681472006-07-27 23:44:37 +0000197- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
198 lost that tests are sorted by name before being run. This rarely
199 matters for well-written tests, but can create baffling symptoms if
200 side effects from one test to the next affect outcomes. ``DocTestFinder``
201 has been changed to sort the list of tests it returns.
202
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000203- The distutils version has been changed to 2.5.0, and are now kept
204 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000205
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000206- Bug #978833: Really close underlying socket in _socketobject.close.
207
Georg Brandl0619a322006-07-26 07:40:17 +0000208- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
209 with title().
210
Georg Brandlcf0c1722006-07-26 07:23:32 +0000211- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
212 to recursive calls and call it with the failing package name.
213
Martin v. Löwis0b483032006-07-25 09:53:12 +0000214- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
215
Georg Brandlc13c34c2006-07-24 14:09:56 +0000216- Patch #1515343: Fix printing of deprecated string exceptions with a
217 value in the traceback module.
218
Greg Ward48fae7a2006-07-23 16:05:51 +0000219- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
220
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000221- Patch #1524429: Use repr() instead of backticks in Tkinter again.
222
Brett Cannoncaebe222006-07-18 04:41:36 +0000223- Bug #1520914: Change time.strftime() to accept a zero for any position in its
224 argument tuple. For arguments where zero is illegal, the value is forced to
225 the minimum value that is correct. This is to support an undocumented but
226 common way people used to fill in inconsequential information in the time
227 tuple pre-2.4.
228
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000229- Patch #1220874: Update the binhex module for Mach-O.
230
Barry Warsawb110bad2006-07-21 14:51:07 +0000231- The email package has improved RFC 2231 support, specifically for
232 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
233 (name*0=<blah>) parameter continuations. This may change the types of
234 values returned from email.message.Message.get_param() and friends.
235 Specifically in some cases where non-encoded continuations were used,
236 get_param() used to return a 3-tuple of (None, None, string) whereas now it
237 will just return the string (since non-encoded continuations don't have
238 charset and language parts).
239
240 Also, whereas % values were decoded in all parameter continuations, they are
241 now only decoded in encoded parameter parts.
242
Ronald Oussoren3075e162006-07-25 20:28:55 +0000243- Bug #1517990: IDLE keybindings on MacOS X now work correctly
244
245- Bug #1517996: IDLE now longer shows the default Tk menu when a
246 path browser, class browser or debugger is the frontmost window on MacOS X
247
Barry Warsaw00decd72006-07-27 23:43:15 +0000248- Patch #1520294: Support for getset and member descriptors in types.py,
249 inspect.py, and pydoc.py. Specifically, this allows for querying the type
250 of an object against these built-in types and more importantly, for getting
251 their docstrings printed in the interactive interpreter's help() function.
252
Ronald Oussoren3075e162006-07-25 20:28:55 +0000253
Neal Norwitza1f10902006-07-12 07:28:29 +0000254Extension Modules
255-----------------
256
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000257- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
258 a socket operation on a socket with a timeout, the exception will be
259 caught correctly. Previously, the exception was not caught.
260
Thomas Heller1393d6a2006-07-28 21:43:20 +0000261- Patch #1529514: The _ctypes extension is now compiled on more
262 openbsd target platforms.
263
Tim Peters9cab5932006-07-28 00:30:00 +0000264- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
265 a memory leak, affecting pickles and deep copies.
266
Tim Petersbc24eee2006-07-27 01:14:53 +0000267- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

269
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000270- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
271
Thomas Hellerce049a02006-07-14 17:51:14 +0000272- Patch #1521817: Index range checking on ctypes arrays containing
273 exactly one element enabled again. This allows iterating over these
274 arrays, without the need to check the array size before.
275
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000276- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000277 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000278 /dev/null in certain cases; this is now fixed.
279
Thomas Heller47d7a062006-07-12 08:43:47 +0000280- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
281 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000282
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000283- Because of a misspelled preprocessor symbol, ctypes was always
284 compiled without thread support; this is now fixed.
285
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000286- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
287 methods now allow their database parameter to be None as the
288 sleepycat API allows.
289
Matt Flemingec926502006-07-28 11:27:27 +0000290- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
291 bluetooth API compared with Linux and FreeBSD.
292
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000293Tests
294-----
295
296- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
297 how long the test file should take to play. Now accepts taking 2.93 secs
298 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
299
Georg Brandl4793aa32006-07-28 18:31:39 +0000300- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
301 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
302 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000303
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000304Build

307- Bug #1439538: Drop usage of test -e in configure as it is not portable.
308
Ronald Oussoren26cad082006-08-01 21:00:57 +0000309Mac
310---
311
312- PythonLauncher now works correctly when the path to the script contains
313 characters that are treated specially by the shell (such as quotes).
314
315- Bug #1527397: PythonLauncher now launches scripts with the working directory
316 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000317 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000318 expect.

326Core and builtins
327-----------------
328
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000329- Bug #1441486: The literal representation of -(sys.maxint - 1)
330 again evaluates to a int object, not a long.
331
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000332- Bug #1501934: The scope of global variables that are locally assigned
333 using augmented assignment is now correctly determined.
334
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000335- Bug #927248: Recursive method-wrapper objects can now safely
336 be released.
337
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000338- Bug #1417699: Reject locale-specific decimal point in float()
339 and atof().
340
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000341- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
342 omit a default "error" argument for NULL pointer. This allows
343 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000344
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000345- Bug #1519018: 'as' is now validated properly in import statements.
346
Neal Norwitz28746ab2006-07-09 22:14:42 +0000347- On 64 bit systems, int literals that use less than 64 bits are
348 now ints rather than longs.
349
Neal Norwitzed657552006-07-10 00:04:44 +0000350- Bug #1512814, Fix incorrect lineno's when code at module scope
351 started after line 256.
352
Tim Peters32a83612006-07-10 21:08:24 +0000353- New function ``sys._current_frames()`` returns a dict mapping thread
354 id to topmost thread stack frame. This is for expert use, and is
355 especially useful for debugging application deadlocks. The functionality
356 was previously available in Fazal Majid's ``threadframe`` extension
357 module, but it wasn't possible to do this in a wholly threadsafe way from
358 an extension.

361-------
362
Martin v. Löwis77621582006-07-30 13:27:31 +0000363- Bug #1257728: Mention Cygwin in distutils error message about a missing
364 VS 2003.
365
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000366- Patch #1519566: Update turtle demo, make begin_fill idempotent.
367
Tim Peters32a83612006-07-10 21:08:24 +0000368- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000369 environment variable to be set in order to the SDK environment
370 for finding the compiler, include files, etc.
371

Nick Coghlan2d792252006-07-06 13:47:18 +0000374- warnings.py now ignores ImportWarning by default
375
Thomas Woutersadd19112006-07-05 11:03:49 +0000376- string.Template() now correctly handles tuple-values. Previously,
377 multi-value tuples would raise an exception and single-value tuples would
378 be treated as the value they contain, instead.
379
Martin v. Löwisede77f52006-07-03 13:01:35 +0000380- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
381 even if some data are received.
382
Martin v. Löwis45482392006-07-03 12:28:58 +0000383- Bug #1267547: Put proper recursive setup.py call into the
384 spec file generated by bdist_rpm.

387 degrees and radians.
388
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000389- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000390 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000391
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000392- Bug #1514703: Only setup canvas window in turtle when the canvas
393 is created.
394
Martin v. Löwis7596e832006-07-01 15:33:37 +0000395- Bug #1513223: .close() of a _socketobj now releases the underlying
396 socket again, which then gets closed as it becomes unreferenced.
397
Fred Drake10497c82006-06-29 02:57:48 +0000398- Bug #1504333: Make sgmllib support angle brackets in quoted
399 attribute values.
400
401- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
402 sgmllib ('[' and ']' were not accepted).
403
Georg Brandl1be63af2006-06-28 20:23:25 +0000404- Fix a bug in the turtle module's end_fill function.
405
Brett Cannon53ab5b72006-06-22 16:49:14 +0000406- Bug #1510580: The 'warnings' module improperly required that a Warning
407 category be either a types.ClassType and a subclass of Warning. The proper
408 check is just that it is a subclass with Warning as the documentation states.
409
Georg Brandlad29e632006-06-21 17:45:17 +0000410- The compiler module now correctly compiles the new try-except-finally
411 statement (bug #1509132).
412
Neal Norwitz60373cd2006-06-22 06:30:50 +0000413- The wsgiref package is now installed properly on Unix.
414
Vinay Sajip28e57612006-07-01 10:45:20 +0000415- A bug was fixed in logging.config.fileConfig() which caused a crash on
416 shutdown when fileConfig() was called multiple times.
417
Gerhard Häring762fbd32006-07-02 17:48:30 +0000418- The sqlite3 module did cut off data from the SQLite database at the first
419 null character before sending it to a custom converter. This has been fixed
420 now.
421
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000422Extension Modules
423-----------------
424
Tim Peters112aad32006-07-19 00:03:19 +0000425- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
426 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
427 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000428
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000429- Assigning None to pointer type fields in ctypes structures possible
430 overwrote the wrong fields, this is fixed now.
431
432- Fixed a segfault in _ctypes when ctypes.wintypes were imported
433 on non-Windows platforms.
434
435- Bug #1518190: The ctypes.c_void_p constructor now accepts any
436 integer or long, without range checking.
437
438- Patch #1517790: It is now possible to use custom objects in the ctypes
439 foreign function argtypes sequence as long as they provide a from_param
440 method, no longer is it required that the object is a ctypes type.
441
442- The '_ctypes' extension module now works when Python is configured
443 with the --without-threads option.
444
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000445- Bug #1513646: os.access on Windows now correctly determines write
446 access, again.
447
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000448- Bug #1512695: cPickle.loads could crash if it was interrupted with
449 a KeyboardInterrupt.
450
Neal Norwitza12aa882006-07-06 06:45:08 +0000451- Bug #1296433: parsing XML with a non-default encoding and
452 a CharacterDataHandler could crash the interpreter in pyexpat.
453
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000454- Patch #1516912: improve Modules support for OpenVMS.
455
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000456Build
457-----
458
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000459- Automate Windows build process for the Win64 SSL module.
460
Tim Peters32a83612006-07-10 21:08:24 +0000461- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000462 Previously, the slight difference could cause compilation errors of the
463 'zlib' module on systems with more than one version of zlib.
464
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000465- The MSI compileall step was fixed to also support a TARGETDIR
466 with spaces in it.
467
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000468- Bug #1517388: sqlite3.dll is now installed on Windows independent
469 of Tcl/Tk.
470
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000471- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000472 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000474Tests
475-----
476
477- Call os.waitpid() at the end of tests that spawn child processes in order
478 to minimize resources (zombies).
479
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000480Documentation
481-------------
482
Nick Coghlan2d792252006-07-06 13:47:18 +0000483- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
484 documentation for the warnings module.
485
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000486- Patch #1509163: MS Toolkit Compiler no longer available.
487
Neal Norwitz56640df2006-07-10 02:36:41 +0000488- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000491What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000492================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000493

Anthony Baxter51bcb682006-04-05 14:51:42 +0000495
496Core and builtins
497-----------------
498
Georg Brandla56b9152006-06-19 06:35:54 +0000499- Patch #1507676: Error messages returned by invalid abstract object operations
500 (such as iterating over an integer) have been improved and now include the
501 type of the offending object to help with debugging.
502
Brett Cannonea3912b2006-06-13 21:46:41 +0000503- Bug #992017: A classic class that defined a __coerce__() method that returned
504 its arguments swapped would infinitely recurse and segfault the interpreter.
505
Neal Norwitz909eb122006-06-12 02:13:21 +0000506- Fix the socket tests so they can be run concurrently.
507
Neal Norwitzb9845e72006-06-12 02:11:18 +0000508- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000509 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000510
Brett Cannon22565aa2006-06-09 22:31:23 +0000511- Bug #532646: object.__call__() will continue looking for the __call__
512 attribute on objects until one without one is found. This leads to recursion
513 when you take a class and set its __call__ attribute to an instance of the
514 class. Originally fixed for classic classes, but this fix is for new-style.
515 Removes the infinite_rec_3 crasher.
516
Georg Brandl24250812006-06-09 18:45:48 +0000517- The string and unicode methods startswith() and endswith() now accept
518 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
519
Brett Cannonde3b0522006-06-08 17:00:45 +0000520- Buffer objects, at the C level, never used the char buffer
521 implementation even when the char buffer for the wrapped object was
522 explicitly requested (originally returned the read or write buffer).
523 Now a TypeError is raised if the char buffer is not present but is
524 requested.
525
Georg Brandlddbaa662006-06-04 21:56:52 +0000526- Patch #1346214: Statements like "if 0: suite" are now again optimized
527 away like they were in Python 2.4.
528
Georg Brandlb7c8f542006-05-27 12:30:25 +0000529- Builtin exceptions are now full-blown new-style classes instead of
530 instances pretending to be classes, which speeds up exception handling
531 by about 80% in comparison to 2.5a2.
532
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000533- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
534 Unicode 4.1.
535
Georg Brandlf4ef1162006-05-26 18:03:31 +0000536- Patch #921466: sys.path_importer_cache is now used to cache valid and
537 invalid file paths for the built-in import machinery which leads to
538 fewer open calls on startup.
539
Tim Peters696cf432006-05-24 21:10:40 +0000540- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
541 of-2 bases. The largest speedup is for inputs with about 1000 decimal
542 digits. Conversion from non-power-of-2 bases remains quadratic-time in
543 the number of input digits (it was and remains linear-time for bases
544 2, 4, 8, 16 and 32).
545
Tim Petersb713ec22006-05-23 18:45:30 +0000546- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
547 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
548 an integer close to ``sys.maxint``. This was repaired by patch
549 #1335972, which also gives a nice speedup.
550
Richard Jonescebbefc2006-05-23 18:28:17 +0000551- Patch #1337051: reduced size of frame objects.
552
553- PyErr_NewException now accepts a tuple of base classes as its
554 "base" parameter.
555
Richard Jones7c88dcc2006-05-23 10:37:38 +0000556- Patch #876206: function call speedup by retaining allocated frame
557 objects.
558
Georg Brandl7b90e162006-05-18 07:01:27 +0000559- Bug #1462152: file() now checks more thoroughly for invalid mode
560 strings and removes a possible "U" before passing the mode to the
561 C library function.
562
Neal Norwitz1004a532006-05-15 07:17:23 +0000563- Patch #1488312, Fix memory alignment problem on SPARC in unicode
564
Neal Norwitz373f0a72006-05-15 07:04:36 +0000565- Bug #1487966: Fix SystemError with conditional expression in assignment
566
Martin v. Löwis879768d2006-05-11 13:28:43 +0000567- WindowsError now has two error code attributes: errno, which carries
568 the error values from errno.h, and winerror, which carries the error
569 values from winerror.h. Previous versions put the winerror.h values
570 (from GetLastError()) into the errno attribute.
571
Martin v. Löwis77736712006-05-04 05:51:03 +0000572- Patch #1475845: Raise IndentationError for unexpected indent.
573
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000574- Patch #1479181: split open() and file() from being aliases for each other.
575
Tim Peters44bd9862006-06-01 13:49:23 +0000576- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
577 methods were always silently ignored by dictionaries when comparing keys.
578 They are now passed through (except when using the C API function
579 ``PyDict_GetItem()``, whose semantics did not change).
580
581- Bug #1456209: In some obscure cases it was possible for a class with a
582 custom ``__eq__()`` method to confuse dict internals when class instances
583 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
584 No, you don't have any code that did this ;-)

590
591- Patch #1462338: Upgrade pyexpat to expat 2.0.0
592
Brett Cannon6ee7d012006-06-08 16:23:04 +0000593- Change binascii.hexlify to accept a read-only buffer instead of only a char
594 buffer and actually follow its documentation.
595
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000596- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
597
Nick Coghlanc649ec52006-05-29 12:43:05 +0000598- Patch #1478788 (modified version): The functional extension module has
599 been renamed to _functools and a functools Python wrapper module added.
600 This provides a home for additional function related utilities that are
601 not specifically about functional programming. See PEP 309.
602
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000603- Patch #1493701: performance enhancements for struct module.
604
Georg Brandl378d5922006-05-17 14:26:50 +0000605- Patch #1490224: time.altzone is now set correctly on Cygwin.
606
Georg Brandl8d3342b2006-05-16 07:38:27 +0000607- Patch #1435422: zlib's compress and decompress objects now have a
608 copy() method.
609
Andrew MacIntyre92913322006-06-13 15:04:24 +0000610- Patch #1454481: thread stack size is now tunable at runtime for thread
611 enabled builds on Windows and systems with Posix threads support.
612
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000613- On Win32, os.listdir now supports arbitrarily-long Unicode path names
614 (up to the system limit of 32K characters).
615
616- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
617 As a result, these functions now raise WindowsError instead of OSError.
618
Tim Peters7a822da2006-05-25 21:50:17 +0000619- ``time.clock()`` on Win64 should use the high-performance Windows
620 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
621 Windows platforms).
622
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000623- Calling Tk_Init twice is refused if the first call failed as that

625
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000626- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
627 accept it without potentially using an uninitialized pointer.
628
629- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
630 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

635
Gregory P. Smith372b5832006-06-05 18:48:21 +0000636- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
637 parameter is supplied. [SF pybsddb bug #1477863]
638
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000639- bsddb: the __len__ method of a DB object has been fixed to return correct
640 results. It could previously incorrectly return 0 in some cases.
641 Fixes SF bug 1493322 (pybsddb bug 1184012).
642
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000643- bsddb: the bsddb.dbtables Modify method now raises the proper error and
644 aborts the db transaction safely when a modifier callback fails.
645 Fixes SF python patch/bug #1408584.
646
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000647- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000648 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000649 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
650 database calls that would previously deadlock. [SF python bug #775414]

681
Tim Peters43898b42006-06-14 04:09:25 +0000682- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
683 guarantee that adjacent triples in the return list always describe
684 non-adjacent blocks. Previously, a pair of matching blocks could end
685 up being described by multiple adjacent triples that formed a partition
686 of the matching pair.

695
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000696- The wsgiref package has been added to the standard library.
697
Nick Coghlan676725d2006-06-08 13:54:49 +0000698- The functions update_wrapper() and wraps() have been added to the functools
699 module. These make it easier to copy relevant metadata from the original
700 function when writing wrapper functions.
701
Tim Petersd6a9eef2006-06-05 01:48:21 +0000702- The optional ``isprivate`` argument to ``doctest.testmod()``, and the

Martin v. Löwis3f767792006-06-04 19:36:28 +0000705- Patch #1359618: Speed up charmap encoder by using a trie structure
706 for lookup.
707
Tim Petersd609b1a2006-06-02 23:22:51 +0000708- The functions in the ``pprint`` module now sort dictionaries by key
709 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
710 if and only if its display required more than one line, although that
711 wasn't documented. The new behavior increases predictability; e.g.,
712 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
713

Georg Brandlb89316f2006-05-17 15:51:16 +0000724- Patch #1180296: Two new functions were added to the locale module:
725 format_string() to get the effect of "format % items" but locale-aware,
726 and currency() to format a monetary number with currency sign.
727

735 stdout arguments, making it possible to redirect input and output
736 for remote debugging.
737
738- Patch #1484695: Update the tarfile module to version 0.8. This fixes
739 a couple of issues, notably handling of long file names using the
740 GNU LONGNAME extension.
741
742- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
743 new flag when ``name`` is already the name of an option flag.

788
789Core and builtins
790-----------------
791
Thomas Heller1b046642006-04-18 18:51:06 +0000792- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
793 by converting these apis from macros into exported functions again:
794
795 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
796 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
797 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
798 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
799 PyRun_String Py_CompileString
800
Martin v. Löwis45294a92006-04-18 06:24:08 +0000801- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
802
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000803- All uses of PyStructSequence_InitType have been changed to initialize
804 the type objects only once, even if the interpreter is initialized
805 multiple times.
806
Neal Norwitz61546162006-04-14 05:20:28 +0000807- Bug #1454485, array.array('u') could crash the interpreter. This was
808 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
809 to unicode when it didn't make sense. 'u#' now requires a unicode string.
810
811- Py_UNICODE is unsigned. It was always documented as unsigned, but
812 due to a bug had a signed value in previous versions.
813
Tim Peters3a5e8b12006-04-11 01:44:07 +0000814- Patch #837242: ``id()`` of any Python object always gives a positive
815 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
816 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000817 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000818 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000819
Tim Peters3a5e8b12006-04-11 01:44:07 +0000820 def __hash__(self):
821 return id(self) # WRONG
822
823 because a hash result must be a (short) Python int but it was always
824 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000825 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000826 was always usable as a hash value before this patch. That's no longer
827 necessarily so.
828
829- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000830 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000831 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000832 #1454844)
833
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000834- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
835 involving generators that have paused outside of any ``try`` or ``with``
836 blocks. (In 2.5a1, a paused generator that was part of a reference
837 cycle could not be garbage collected, regardless of whether it was
838 paused in a ``try`` or ``with`` block.)

868 abusing errno.
869
Tim Peters711bf302006-04-25 03:31:36 +0000870- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes

872 or exception is ignored).
873

875 caught inside exit handlers.
876
Greg Wardab05edc2006-04-23 03:47:58 +0000877- Updated optparse module to Optik 1.5.1 (allow numeric constants in
878 hex, octal, or binary; add ``append_const`` action; keep going if
879 gettext cannot be imported; added ``OptionParser.destroy()`` method;
880 added ``epilog`` for better help generation).
881
Tim Peters21fbd572006-04-21 21:18:10 +0000882- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
883 called from a thread spawned as a side effect of importing a module.
884
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000885- The pydoc module now supports documenting packages contained in
886 .zip or .egg files.
887
888- The pkgutil module now has several new utility functions, such
889 as ``walk_packages()`` to support working with packages that are either
890 in the filesystem or zip files.
891
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000892- The mailbox module can now modify and delete messages from
893 mailboxes, in addition to simply reading them. Thanks to Gregory
894 K. Johnson for writing the code, and to the 2005 Google Summer of
895 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000896
Tim Petersc7605f22006-04-17 21:12:33 +0000897- The ``__del__`` method of class ``local`` in module ``_threading_local``
898 returned before accomplishing any of its intended cleanup.

Martin v. Löwis10acfd02006-04-10 12:39:36 +0000938- Patch #1429775: Link extension modules with the shared libpython.
939
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000940- Fixed a libffi build problem on MIPS systems.
941
Tim Peters8931ff12006-05-13 23:28:20 +0000942- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
943 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
944 and "%zu" for unsigned integers of type ``size_t``.
945
Anthony Baxter51bcb682006-04-05 14:51:42 +0000946Tests
947-----
948
Nick Coghlanda2268f2006-04-24 04:37:15 +0000949- test_contextlib now checks contextlib.nested can cope with exceptions
950 being raised and caught inside exit handlers.
951
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000952- test_cmd_line now checks operation of the -m and -c command switches
953
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000954- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
955 it separately and by hand. It also wasn't cleaning up its changes to
956 the current Decimal context.
957
Thomas Woutersabd08882006-04-26 15:53:30 +0000958- regrtest.py now has a -M option to run tests that test the new limits of
959 containers, on 64-bit architectures. Running these tests is only sensible
960 on 64-bit machines with more than two gigabytes of memory. The argument
961 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000969Documentation
970-------------
971
Tim Petersb06d28c2006-05-12 01:57:59 +0000972- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
973
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000974- PEP 343: Added Context Types section to the library reference
975 and attempted to bring other PEP 343 related documentation into
976 line with the implementation and/or python-dev discussions.
977
Tim Peters8dc73d22006-04-24 02:03:16 +0000978- Bug #1337990: clarified that ``doctest`` does not support examples
979 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000982What's New in Python 2.5 alpha 1?
983=================================
984
Anthony Baxterebed3f62006-04-03 15:03:44 +0000985*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000986
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000987Core and builtins
988-----------------
989
Nick Coghlan43832302006-04-23 17:04:07 +0000990- PEP 338: -m command line switch now delegates to runpy.run_module
991 allowing it to support modules in packages and zipfiles
992
Martin v. Löwisc661b882006-04-20 04:54:23 +0000993- On Windows, .DLL is not an accepted file name extension for
994 extension modules anymore; extensions are only found if they
995 end in .PYD.
996
Martin v. Löwisea62d252006-04-03 10:56:49 +0000997- Bug #1421664: sys.stderr.encoding is now set to the same value as
998 sys.stdout.encoding.
999
Neal Norwitz92e212f2006-04-03 04:48:37 +00001000- __import__ accepts keyword arguments.
1001
Georg Brandlccadf842006-03-31 18:54:53 +00001002- Patch #1460496: round() now accepts keyword arguments.
1003
Anthony Baxter262c00a2006-03-30 10:53:17 +00001004- Fixed bug #1459029 - unicode reprs were double-escaped.
1005
Hye-Shik Changd478f342006-03-23 12:32:36 +00001006- Patch #1396919: The system scope threads are reenabled on FreeBSD
1007 5.4 and later versions.
1008
Neal Norwitze98ccf62006-03-23 05:39:47 +00001009- Bug #1115379: Compiling a Unicode string with an encoding declaration
1010 now gives a SyntaxError.
1011
Georg Brandlabd1ff82006-03-18 07:59:59 +00001012- Previously, Python code had no easy way to access the contents of a
1013 cell object. Now, a ``cell_contents`` attribute has been added
1014 (closes patch #1170323).
1015
Tim Peterscf79aac2006-03-16 01:14:46 +00001016- Patch #1123430: Python's small-object allocator now returns an arena to
1017 the system ``free()`` when all memory within an arena becomes unused
1018 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1019 freed. Some applications will see a drop in virtual memory size now,
1020 especially long-running applications that, from time to time, temporarily
1021 use a large number of small objects. Note that when Python returns an
1022 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001023 platform C library will in turn return that memory to the operating system.
1024 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001025 appears to be effective at least on Microsoft C and gcc-based systems.
1026 Thanks to Evan Jones for hard work and patience.
1027
Georg Brandl533ff6f2006-03-08 18:09:27 +00001028- Patch #1434038: property() now uses the getter's docstring if there is
1029 no "doc" argument given. This makes it possible to legitimately use
1030 property() as a decorator to produce a read-only property.
1031
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001032- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1033 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1034 of requiring an int or long in slicing and a few other contexts, enabling
1035 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1036
Neal Norwitz995acdf2006-03-07 05:01:00 +00001037- Fixed various bugs reported by Coverity's Prevent tool.
1038
Brett Cannonbf364092006-03-01 04:25:17 +00001039- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1040 new exception base class, BaseException, which has a new message attribute.
1041 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1042 Raising a string exception now raises a DeprecationWarning.
1043
Thomas Woutersfb609f42006-02-28 16:37:25 +00001044- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1045 explicitly relative, using 'from .module import name' to mean 'from the same
1046 package as this module is in. Imports without dots still default to the
1047 old relative-then-absolute, unless 'from __future__ import
1048 absolute_import' is used.
1049
Brett Cannona7446e32006-02-27 23:39:10 +00001050- Properly check if 'warnings' raises an exception (usually when a filter set
1051 to "error" is triggered) when raising a warning for raising string
1052 exceptions.
1053
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001054- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001055 The name was removed from Include/code.h.
1056
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001057- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001058
Guido van Rossum1968ad32006-02-25 22:38:04 +00001059- Patch 1433928:
1060 - The copy module now "copies" function objects (as atomic objects).
1061 - dict.__getitem__ now looks for a __missing__ hook before raising
1062 KeyError.
1063
Tim Peters84ef21c2006-02-28 20:39:06 +00001064- PEP 343: with statement implemented. Needs ``from __future__ import
1065 with_statement``. Use of 'with' as a variable will generate a warning.
1066 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001067 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001068 The following objects have __context__ methods:
1069 - The built-in file type.
1070 - The thread.LockType type.
1071 - The following types defined by the threading module:
1072 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1073 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001074
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001075- Fix the encodings package codec search function to only search
1076 inside its own package. Fixes problem reported in patch #1433198.
1077
1078 Note: Codec packages should implement and register their own
1079 codec search function. PEP 100 has the details.
1080
Tim Peters9ea89d22006-06-04 03:26:02 +00001081- PEP 353: Using ``Py_ssize_t`` as the index type.
1082
1083- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1084 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1085 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1086 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1087 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001088
Neal Norwitzfc76d632006-01-10 06:03:13 +00001089- Patch #1400181, fix unicode string formatting to not use the locale.
1090 This is how string objects work. u'%f' could use , instead of .
1091 for the decimal point. Now both strings and unicode always use periods.
1092
Neal Norwitz671b9e32006-01-09 07:07:12 +00001093- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1094 configure would break checking curses.h.
1095
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001096- Bug #959576: The pwd module is now builtin. This allows Python to be
1097 built on UNIX platforms without $HOME set.
1098
Neal Norwitzc10978f2005-12-19 06:07:16 +00001099- Bug #1072182, fix some potential problems if characters are signed.
1100
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001101- Bug #889500, fix line number on SyntaxWarning for global declarations.
1102
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001103- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1104
Neal Norwitze7214a12005-12-18 05:03:17 +00001105- Support for converting hex strings to floats no longer works.
1106 This was not portable. float('0x3') now raises a ValueError.
1107
Barry Warsaw2a38a862005-12-18 01:27:35 +00001108- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001109 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001110 is now displayed in interactive prompt banner.
1111
Georg Brandlfa166682005-12-17 21:45:17 +00001112- Implementation of PEP 341 - Unification of try/except and try/finally.
1113 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001114 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001115
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001116- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1117 now encodes backslash correctly.
1118
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001119- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1120
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001121- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001122 and long longs.
1123
Neal Norwitz67715f02005-11-09 06:59:35 +00001124- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001125 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001126 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001127
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001128- Replaced most Unicode charmap codecs with new ones using the
1129 new Unicode translate string feature in the builtin charmap
1130 codec; the codecs were created from the mapping tables available
1131 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1132 encodings now include a mapping for the Apple logo)
1133
Tim Peterse3547fd2005-12-16 23:13:57 +00001134- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001135
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001136- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001137
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001138- A new AST parser implementation was completed. The abstract
1139 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001140 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001141
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001142- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001143 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1144
Neal Norwitz708e51a2005-10-03 04:48:15 +00001145- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1146
Neal Norwitz11bd1192005-10-03 00:54:56 +00001147- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1148 Provide a warning when a directory is passed on the command line.
1149
Neal Norwitz40d37812005-10-02 01:48:49 +00001150- Fix segfault with invalid coding.
1151
1152- SF bug #772896: unknown encoding results in MemoryError.
1153
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001154- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001155 supported a __len__() method which evaluated to False when the iterator
1156 was empty.
1157
Guido van Rossum630db602005-09-20 18:49:54 +00001158- On 64-bit platforms, when __len__() returns a value that cannot be
1159 represented as a C int, raise OverflowError.
1160
Skip Montanarof8948ca2005-09-19 03:54:46 +00001161- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001162 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001163
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001164- SF bug #893549: parsing keyword arguments was broken with a few format
1165 codes.
1166
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001167- Changes donated by Elemental Security to make it work on AIX 5.3
1168 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1169 bug #105470: test_pwd fails on 64bit system (Opteron).
1170
Guido van Rossum539c6622005-09-14 17:49:54 +00001171- Changes donated by Elemental Security to make it work on HP-UX 11 on
1172 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1173
Georg Brandl4550b8d2005-08-26 06:43:52 +00001174- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001175 (fixes bug #1119418).
1176
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001177- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1178
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001179- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1180 exceptions that cause a function to exit.
1181
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001182- The implementation of set() and frozenset() was revised to use its
1183 own internal data structure. Memory consumption is reduced by 1/3
1184 and there are modest speed-ups as well. The API is unchanged.
1185
Tim Petersde7990b2005-07-17 23:45:23 +00001186- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1187
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001188- SF bug #1229429: PyObject_CallMethod failed to decrement some
1189 reference counts in some error exit cases.
1190
Tim Petersecc6e6a2005-07-10 22:30:55 +00001191- SF bug #1185883: Python's small-object memory allocator took over
1192 a block managed by the platform C library whenever a realloc specified
1193 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001194 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001195 portable way to copy data from the C-managed block into Python's
1196 small-object space without risking a memory fault. Python's small-object
1197 realloc now leaves such blocks under the control of the platform C
1198 realloc.
1199
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001200- SF bug #1232517: An overflow error was not detected properly when
1201 attempting to convert a large float to an int in os.utime().
1202
Raymond Hettinger3296e692005-06-29 23:29:56 +00001203- SF bug #1224347: hex longs now print with lowercase letters just
1204 like their int counterparts.
1205
Michael W. Hudson188d4362005-06-20 16:52:57 +00001206- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1207 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1208 interpreter states; back out that fix and do a better job (see

1210 for a longer write-up of the problem).
1211
Michael W. Hudsondf888462005-06-03 14:41:55 +00001212- SF patch #1180995: marshal now uses a binary format by default when
1213 serializing floats.
1214
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001215- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1216 the routines that promise to produce IEEE 754 binary representations
1217 of floats now simply copy bytes around.
1218
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001219- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1220 278.
1221
Brett Cannonc3647ac2005-04-26 03:45:26 +00001222- patch #1109424: int, long, float, complex, and unicode now check for the
1223 proper magic slot for type conversions when subclassed. Previously the
1224 magic slot was ignored during conversion. Semantics now match the way
1225 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001226 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001227 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001228 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001229
Barry Warsawc8d907c2005-04-19 23:43:40 +00001230- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1231 NULL, now raise an AttributeError when attempting to set or delete the
1232 attribute. Previously a TypeError was raised, but this was inconsistent
1233 with the equivalent pure-Python implementation.
1234
Michael W. Hudson774479c2005-04-18 08:46:17 +00001235- It is now safe to call PyGILState_Release() before
1236 PyEval_InitThreads() (note that if there is reason to believe there
1237 are multiple threads around you still must call PyEval_InitThreads()
1238 before using the Python API; this fix is for extension modules that
1239 have no way of knowing if Python is multi-threaded yet).
1240
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001241- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1242 disabled caused a crash.
1243
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001244- Bug #1165306: instancemethod_new allowed the creation of a method
1245 with im_class == im_self == NULL, which caused a crash when called.
1246
Tim Petersecc6e6a2005-07-10 22:30:55 +00001247- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001248 fixes the crash seen in bug #1165761
1249
Raymond Hettinger96229b12005-03-11 06:49:40 +00001250- Added two new builtins, any() and all().
1251
Brett Cannon409d8f22005-03-05 06:47:57 +00001252- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001253 (e.g., ``class C(): pass`` is no longer a syntax error).
1254 Patch #1176012 added support to the 'parser' module and 'compiler' package
1255 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001256
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001257- Patch #1115086: Support PY_LONGLONG in structmember.
1258
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001259- Bug #1155938: new style classes did not check that __init__() was
1260 returning None.
1261
Tim Petersecc6e6a2005-07-10 22:30:55 +00001262- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001263 ('\') with a specific error message.
1264
Martin v. Löwisff232d72005-03-03 09:24:38 +00001265- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1266
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001267- Bug #1124295: the __name__ attribute of file objects was
1268 inadvertently made inaccessible in restricted mode.
1269
Tim Petersecc6e6a2005-07-10 22:30:55 +00001270- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001271 an ferror() call.
1272
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001273- min() and max() now support key= arguments with the same meaning as in
1274 list.sort().
1275
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001276- The peephole optimizer now performs simple constant folding in expressions:
1277 (2+3) --> (5).
1278
Raymond Hettingera422c342005-01-11 03:03:27 +00001279- set and frozenset objects can now be marshalled. SF #1098985.
1280
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001281- Bug #1077106: Poor argument checking could cause memory corruption
1282 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001283
Jeremy Hyltonab630502005-02-04 18:44:06 +00001284- The parser did not complain about future statements in illegal
1285 positions. It once again reports a syntax error if a future
1286 statement occurs after anything other than a doc string.
1287
Neil Schemenauercf52c072005-08-12 17:34:58 +00001288- Change the %s format specifier for str objects so that it returns a
1289 unicode instance if the argument is not an instance of basestring and
1290 calling __str__ on the argument returns a unicode instance.
1291
Tim Petersf4e69282006-02-27 17:15:31 +00001292- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1293 current thread state when the auto-GIL-state machinery knows about
1294 it (since the thread state is being deleted, continuing to remember it
1295 can't help, but can hurt if another thread happens to get created with
1296 the same thread id).

1326 for applications that require this specific version (such as IDNA).
1327
Neal Norwitzb62c4332006-03-04 18:35:47 +00001328- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001488- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1489 been renamed to have only a single underscore prefix. This was done to
1490 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001491
Nick Coghlan43832302006-04-23 17:04:07 +00001492- PEP 338: new module runpy defines a run_module function to support
1493 executing modules which provide access to source code or a code object
1494 via the PEP 302 import mechanisms.
1495
Anthony Baxter93f5b932006-04-03 08:05:07 +00001496- The email module's parsedate_tz function now sets the daylight savings

1504 in attribute values.
1505
Anthony Baxterc51ee692006-04-01 00:57:31 +00001506- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001507 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001508 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001509 module will not be built.
1510
Tim Petersc17976e2006-04-01 00:26:53 +00001511- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1512 aren't officially supported here, and trying to use them will probably
1513 raise an exception some day. But dicts have been allowed, and "mostly
1514 worked", so support for them won't go away without warning.
1515
Georg Brandl338ef7d2006-03-31 18:42:16 +00001516- Bug #1445068: getpass.getpass() can now be given an explicit stream

1534
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001535- email 4.0 package now integrated. This is largely the same as the email 3.0
1536 package that was included in Python 2.3, except that PEP 8 module names are
1537 now used (e.g. mail.message instead of email.Message). The MIME classes
1538 have been moved to a subpackage (e.g. email.mime.text instead of
1539 email.MIMEText). The old names are still supported for now. Several
1540 deprecated Message methods have been removed and lots of bugs have been
1541 fixed. More details can be found in the email package documentation.
1542
Walter Dörwald40108c92006-03-27 08:15:44 +00001543- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1544 (a subclass of tuple) that provides incremental decoders and encoders
1545 (a way to use stateful codecs without the stream API). Python functions
1546 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1547 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1548 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001549
Walter Dörwald067db482006-03-15 22:17:27 +00001550- Patch #1359365: Calling next() on a closed StringIO.String object raises
1551 a ValueError instead of a StopIteration now (like file and cString.String do).
1552 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1553 called before (like file and StringIO.StringIO do).

1628 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1629 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1630 Ronald L. Rivest offered this advice for Python:
1631
1632 "The consensus of researchers in this area (at least as
1633 expressed at the NIST Hash Function Workshop 10/31/05),
1634 is that SHA-256 is a good choice for the time being, but
1635 that research should continue, and other alternatives may
1636 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001637
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001638- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl9166e1a2005-06-04 09:20:03 +00001738- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1739
Georg Brandl268e61c2005-06-03 14:28:50 +00001740- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1741 component of the path.
1742
Skip Montanaro174dd222005-05-14 20:54:16 +00001743- Patch #1120353: The xmlrpclib module provides better, more transparent,
1744 support for datetime.{datetime,date,time} objects. With use_datetime set
1745 to True, applications shouldn't have to fiddle with the DateTime wrapper
1746 class at all.
1747
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001748- distutils.commands.upload was added to support uploading distribution
1749 files to PyPI.
1750
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001751- distutils.commands.register now encodes the data as UTF-8 before posting
1752 them to PyPI.
1753
Raymond Hettinger267b8682005-03-27 10:47:39 +00001754- decimal operator and comparison methods now return NotImplemented
1755 instead of raising a TypeError when interacting with other types. This
1756 allows other classes to implement __radd__ style methods and have them
1757 work as expected.
1758
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001759- Bug #1163325: Decimal infinities failed to hash. Attempting to
1760 hash a NaN raised an InvalidOperation instead of a TypeError.
1761
Tim Petersecc6e6a2005-07-10 22:30:55 +00001762- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001763 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1764
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001765- Patch #1043890: Add extractall method to tarfile.
1766
Martin v. Löwisc72dd382005-03-04 13:50:17 +00001767- Patch #1075887: Don't require MSVC in distutils if there is nothing
1768 to build.
1769
Martin v. Löwis637431b2005-03-03 23:12:42 +00001770- Patch #1103407: Properly deal with tarfile iterators when untarring
1771 symbolic links on Windows.
1772
Tim Petersecc6e6a2005-07-10 22:30:55 +00001773- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001774 profile.py if available.
1775
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001776- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1777
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001778- Patch #1117454: Remove code to special-case cookies without values
1779 in LWPCookieJar.
1780
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001781- Patch #1117339: Add cookielib special name tests.
1782
Martin v. Löwise869eb12005-03-03 09:46:07 +00001783- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1784
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001785- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1786
Martin v. Löwisdf241532005-03-03 08:17:42 +00001787- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1788
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001789- Patch #1104111: Alter setup.py --help and --help-commands.
1790
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001791- Patch #1121234: Properly cleanup _exit and tkerror commands.
1792
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001793- Patch #1049151: xdrlib now unpacks booleans as True or False.
1794
Raymond Hettingerbab41432005-02-05 01:31:19 +00001795- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1796
Guido van Rossumd0641422005-02-03 15:01:24 +00001797- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1798 disables recursive traversal through instance attributes, which can
1799 be exploited in various ways.
1800
Tim Peterse3547fd2005-12-16 23:13:57 +00001801- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001802 flags on the HTTP listening socket.
1803
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001804- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1805 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1806
Fred Drakefbdeaad2006-07-29 16:56:15 +00001807- Patches #893642, #1039083: add allow_none, encoding arguments to
1808 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001809
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001810- Bug #1110478: Revert os.environ.update to do putenv again.
1811
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001812- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1813
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001814- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1815
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001816- Enhancements to the csv module:
1817
1818 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001819 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001820 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001821 + Dialect parameter parsing has been re-implemented to improve error
1822 reporting.
1823 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1824 dictates.
1825 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001826 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001827 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001828 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1829 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001830 + reader now allows \r characters to be quoted (previously it only allowed
1831 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001832 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001833 + Dialect classes passed to the module are no longer instantiated by
1834 the module before being parsed (the former validation scheme required
1835 this, but the mechanism was unreliable).
1836 + The dialect registry now contains instances of the internal
1837 C-coded dialect type, rather than references to python objects.
1838 + the internal c-coded dialect type is now immutable.
1839 + register_dialect now accepts the same keyword dialect specifications
1840 as the reader and writer, allowing the user to register dialects
1841 without first creating a dialect class.
1842 + a configurable limit to the size of parsed fields has been added -
1843 previously, an unmatched quote character could result in the entire
1844 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001845 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001846 the parser field size limit (returning the former limit). The initial
1847 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001848 + A line_num attribute has been added to the reader object, which tracks
1849 the number of lines read from the source iterator. This is not
1850 the same as the number of records returned, as records can span
1851 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001852 + reader and writer objects were not being registered with the cyclic-GC.
1853 This has been fixed.
1854
Brett Cannone6539c42005-01-08 02:43:53 +00001855- _DummyThread objects in the threading module now delete self.__block that is
1856 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1857 lock primitives tend to be limited in number and thus should not be wasted on
1858 a _DummyThread object. Fixes bug #1089632.
1859
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001860- The imghdr module now detects Exif files.
1861
Raymond Hettinger6065d322004-12-20 23:51:53 +00001862- StringIO.truncate() now correctly adjusts the size attribute.
1863 (Bug #951915).
1864
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001865- locale.py now uses an updated locale alias table (built using
1866 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1867 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001868 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001869
Raymond Hettinger3557f422004-12-07 12:02:02 +00001870- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1871
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001872- the pickle module no longer accepts the deprecated None option in the
1873 args tuple returned by __reduce__().
1874
Brett Cannon84667c02004-12-07 03:25:18 +00001875- optparse now optionally imports gettext. This allows its use in setup.py.
1876
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001877- the pickle module no longer uses the deprecated bin parameter.
1878
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001879- the shelve module no longer uses the deprecated binary parameter.
1880
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001881- the pstats module no longer uses the deprecated ignore() method.
1882
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001883- the filecmp module no longer uses the deprecated use_statcache argument.
1884
Raymond Hettinger664347b2004-12-04 21:21:53 +00001885- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1886 extended or overridden by subclasses. Formerly, the subclassed method would
1887 be ignored by the rest of the module. (Bug #1078905).
1888
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001889- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001890 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001891
Walter Dörwald36733692004-12-22 12:50:50 +00001892- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1893 once when a size argument is given. This prevents a buffer overflow in the
1894 tokenizer with very long source lines.
1895
Barry Warsaw538561e2006-01-01 21:48:54 +00001896- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1897 immediately after creating the object, without any intervening
1898 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001899
Skip Montanaro05885812005-01-16 20:48:27 +00001900- The reconvert.quote function can now emit triple-quoted strings. The
1901 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001902
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001903- ``UserString.MutableString`` now supports negative indices in
1904 ``__setitem__`` and ``__delitem__``
1905
Greg Ward40407942005-03-05 02:53:17 +00001906- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1907 correctly.
1908
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001909- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1910 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1911 character even if the user has passed a size parameter to get a proper
1912 line ending. Remove the special handling of a "\r\n" that has been split
1913 between two lines.
1914
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001915- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1916 about illegal code points. The codec now supports PEP 293 style error
1917 handlers.
1918
Walter Dörwald78a78b02005-09-01 12:04:29 +00001919- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001920 from the input stream, so that the output is a byte string in the correct
1921 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001922
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001923- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1924 considering it exactly like a '*'.
1925
Walter Dörwald007f8df2005-10-09 19:42:27 +00001926- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1927 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001928
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001929- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1930
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001931- Patch #1413711: Certain patterns of differences were making difflib
1932 touch the recursion limit.
1933
Walter Dörwald58917a62006-03-31 15:26:22 +00001934- Bug #947906: An object oriented interface has been added to the calendar
1935 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001936 called as a script (e.g. via ``python -mcalendar``). Localized month and
1937 weekday names can be ouput (even if an exotic encoding is used) using
1938 special classes that use unicode.

1941-----
1942
Neal Norwitz602d3392006-03-31 08:21:40 +00001943- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1944 by using -mieee gcc option.
1945
Martin v. Löwis86d66262006-02-17 08:40:11 +00001946- Patch #1432345: Make python compile on DragonFly.
1947
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001948- Build support for Win64-AMD64 was added.
1949
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001950- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1951
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001952- Patch #881820: look for openpty and forkpty also in libbsd.
1953
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001954- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1955 The zlib module is now builtin on Windows.
1956
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001957- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1958
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001959- Bug #1189330: configure did not correctly determine the necessary
1960 value of LINKCC if python was built with GCC 4.0.
1961
Trent Mick8321b422005-07-26 02:29:21 +00001962- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1963 vulnerability in zlib 1.2.1 and 1.2.2.
1964
Brett Cannon08cd5982005-04-24 22:26:38 +00001965- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1966 flags that change binary compatibility. Changes were also made to
1967 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001968 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001969
Bob Ippolitoed233462005-03-29 13:47:59 +00001970- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1971 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1972 no longer exists). This configure patch makes things right.
1973
Martin v. Löwise2713be2005-03-08 15:03:08 +00001974- Bug #1158607: Build with --disable-unicode again.
1975
Brett Cannon46d96232005-02-16 00:07:19 +00001976- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1977 defined. Discovered as a result of not being able to build on OS X.
1978
Brett Cannon516592f2004-12-07 00:42:59 +00001979- setup.py now uses the directories specified in LDFLAGS using the -L option
1980 and in CPPFLAGS using the -I option for adding library and include
1981 directories, respectively, for compiling extension modules against. This has
1982 led to the core being compiled using the values in CPPFLAGS. It also removes
1983 the need for the special-casing of both DarwinPorts and Fink for darwin since
1984 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1985 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1986 Fink, ``-I/opt/local/include`` for DarwinPorts).
1987
Brett Cannon43802422005-02-10 20:48:03 +00001988- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1989 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1990 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1991 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001993C API
1994-----
1995
Tim Petersc9d78aa2006-03-26 23:27:58 +00001996- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1997 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1998 is obtained via the ``PyObject_`` family, it must be released via the
1999 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2000 always been officially true, but when Python's small-object allocator was
2001 introduced, an attempt was made to cater to a few extension modules
2002 discovered at the time that obtained memory via ``PyObject_New`` but
2003 released it via ``PyMem_DEL``. It's years later, and if such code still
