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 Brandl7a1af772006-08-14 21:55:28 +000067- Patch #1536071: trace.py should now find the full module name of a
68 file correctly even on Windows.
69
Georg Brandl0a7d1bb2006-08-11 07:26:10 +000070- logging's atexit hook now runs even if the rest of the module has
71 already been cleaned up.
72
Guido van Rossum133f4e42006-08-10 17:42:50 +000073- Bug #1112549, DoS attack on cgi.FieldStorage.
74
Neal Norwitzff4b63b2006-08-04 04:50:21 +000075- Bug #1531405, format_exception no longer raises an exception if
76 str(exception) raised an exception.
77
Neil Schemenauer06ded092006-08-04 16:20:30 +000078- Fix a bug in the ``compiler`` package that caused invalid code to be
79 generated for nested functions.
80
Neal Norwitzff4b63b2006-08-04 04:50:21 +000081
82Extension Modules
83-----------------
84
Georg Brandl3335a7a2006-08-14 21:42:55 +000085- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
86 raises the correct exceptions.
87
Thomas Heller1ce433e2006-08-14 16:20:04 +000088- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
89 '-no-stack-protector' compiler flag for OpenBSD has been removed.
90
Thomas Heller86720042006-08-14 11:17:48 +000091- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
92 uses the _as_parameter_ attribute when objects are passed to foreign
93 function calls. The ctypes version number was changed to 1.0.1.
94
Bob Ippolitoe6c9f982006-08-04 23:59:21 +000095- Bug #1530559, struct.pack raises TypeError where it used to convert.
96 Passing float arguments to struct.pack when integers are expected
97 now triggers a DeprecationWarning.
98
Neal Norwitzff4b63b2006-08-04 04:50:21 +000099
100Tests

104
Georg Brandl9908d162006-08-06 07:06:33 +0000105- Bug #1535182: really test the xreadlines() method of bz2 objects.
106
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000107- test_threading now skips testing alternate thread stack sizes on
108 platforms that don't support changing thread stack size.
109
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000110
Georg Brandl212b5872006-08-05 06:10:54 +0000111Documentation

129
Tim Peters4643c2f2006-08-10 22:45:34 +0000130- Bug #1069160. Internal correctness changes were made to
131 ``PyThreadState_SetAsyncExc()``. A test case was added, and
132 the documentation was changed to state that the return value
133 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000140What's New in Python 2.5 beta 3?
141================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000142
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000143*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000144
145Core and builtins
146-----------------
147
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000148- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
149 returned a long (see PEP 353).
150
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000151- Bug #1515471: string.replace() accepts character buffers again.
152
Neal Norwitz07aadb12006-07-30 06:55:48 +0000153- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
154 This provides the proper warning for struct.pack().
155 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
156
Neal Norwitz0d62a062006-07-30 06:53:31 +0000157- Patch #1531113: Fix augmented assignment with yield expressions.
158 Also fix a SystemError when trying to assign to yield expressions.
159
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000160- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
161 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
162 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
163 excessive filesystem operations during imports.
164
Tim Petersbc24eee2006-07-27 01:14:53 +0000165- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
166 operations on signed longs that are formally undefined by C.
167 Unfortunately, at least one compiler now cares about that, so complicated
168 the code to make that compiler happy again.
169
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000170- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
171
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000172- Patch #1232023: Stop including current directory in search
173 path on Windows.
174
Neal Norwitze1fdb322006-07-21 05:32:28 +0000175- Fix some potential crashes found with failmalloc.
176
Neal Norwitze7563102006-07-17 01:00:16 +0000177- Fix warnings reported by Klocwork's static analysis tool.
178
Neal Norwitz84be93b2006-07-16 01:50:38 +0000179- Bug #1512814, Fix incorrect lineno's when code within a function
180 had more than 255 blank lines.
181
Georg Brandl9dceedb2006-07-12 15:31:17 +0000182- Patch #1521179: Python now accepts the standard options ``--help`` and
183 ``--version`` as well as ``/?`` on Windows.
184
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000185- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000186 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000187 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000188
Tim Peters112aad32006-07-19 00:03:19 +0000189- Bug #1524317: Compiling Python ``--without-threads`` failed.
190 The Python core compiles again then, and, in a build without threads, the
191 new ``sys._current_frames()`` returns a dictionary with one entry,
192 mapping the faux "thread id" 0 to the current frame.
193
Ronald Oussoren3075e162006-07-25 20:28:55 +0000194- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000195
Ronald Oussoren3075e162006-07-25 20:28:55 +0000196
Neal Norwitza1f10902006-07-12 07:28:29 +0000197Library
198-------
199
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000200- Correction of patch #1455898: In the mbcs decoder, set final=False
201 for stream decoder, but final=True for the decode function.
202
Georg Brandl07fec3a2006-08-01 18:49:24 +0000203- os.urandom no longer masks unrelated exceptions like SystemExit or
204 KeyboardInterrupt.
205
Tim Peters4643c2f2006-08-10 22:45:34 +0000206- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000207 shutil.copytree on Windows
208
Georg Brandle34ac7c2006-07-30 11:07:23 +0000209- Bug #1002398: The documentation for os.path.sameopenfile now correctly
210 refers to file descriptors, not file objects.
211
Fred Drakefbdeaad2006-07-29 16:56:15 +0000212- Rename of the xml package to xmlcore, and the import hackery done to
213 make it appear at both names, has been removed. Bug #1511497,
214 #1513611, and probably others.
215
Georg Brandledd9b0d2006-07-29 09:33:26 +0000216- Bug #1441397: The compiler module now recognizes module and function
217 docstrings correctly as it did in Python 2.4.
218
Tim Peters6f681472006-07-27 23:44:37 +0000219- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
220 lost that tests are sorted by name before being run. This rarely
221 matters for well-written tests, but can create baffling symptoms if
222 side effects from one test to the next affect outcomes. ``DocTestFinder``
223 has been changed to sort the list of tests it returns.
224
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000225- The distutils version has been changed to 2.5.0, and are now kept
226 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000227
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000228- Bug #978833: Really close underlying socket in _socketobject.close.
229
Georg Brandl0619a322006-07-26 07:40:17 +0000230- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
231 with title().
232
Georg Brandlcf0c1722006-07-26 07:23:32 +0000233- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
234 to recursive calls and call it with the failing package name.
235
Martin v. Löwis0b483032006-07-25 09:53:12 +0000236- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
237
Georg Brandlc13c34c2006-07-24 14:09:56 +0000238- Patch #1515343: Fix printing of deprecated string exceptions with a
239 value in the traceback module.
240
Greg Ward48fae7a2006-07-23 16:05:51 +0000241- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
242
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000243- Patch #1524429: Use repr() instead of backticks in Tkinter again.
244
Brett Cannoncaebe222006-07-18 04:41:36 +0000245- Bug #1520914: Change time.strftime() to accept a zero for any position in its
246 argument tuple. For arguments where zero is illegal, the value is forced to
247 the minimum value that is correct. This is to support an undocumented but
248 common way people used to fill in inconsequential information in the time
249 tuple pre-2.4.
250
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000251- Patch #1220874: Update the binhex module for Mach-O.
252
Barry Warsawb110bad2006-07-21 14:51:07 +0000253- The email package has improved RFC 2231 support, specifically for
254 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
255 (name*0=<blah>) parameter continuations. This may change the types of
256 values returned from email.message.Message.get_param() and friends.
257 Specifically in some cases where non-encoded continuations were used,
258 get_param() used to return a 3-tuple of (None, None, string) whereas now it
259 will just return the string (since non-encoded continuations don't have
260 charset and language parts).
261
262 Also, whereas % values were decoded in all parameter continuations, they are
263 now only decoded in encoded parameter parts.
264
Ronald Oussoren3075e162006-07-25 20:28:55 +0000265- Bug #1517990: IDLE keybindings on MacOS X now work correctly
266
267- Bug #1517996: IDLE now longer shows the default Tk menu when a
268 path browser, class browser or debugger is the frontmost window on MacOS X
269
Barry Warsaw00decd72006-07-27 23:43:15 +0000270- Patch #1520294: Support for getset and member descriptors in types.py,
271 inspect.py, and pydoc.py. Specifically, this allows for querying the type
272 of an object against these built-in types and more importantly, for getting
273 their docstrings printed in the interactive interpreter's help() function.
274
Ronald Oussoren3075e162006-07-25 20:28:55 +0000275
Neal Norwitza1f10902006-07-12 07:28:29 +0000276Extension Modules
277-----------------
278
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000279- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
280 a socket operation on a socket with a timeout, the exception will be
281 caught correctly. Previously, the exception was not caught.
282
Thomas Heller1393d6a2006-07-28 21:43:20 +0000283- Patch #1529514: The _ctypes extension is now compiled on more
284 openbsd target platforms.
285
Tim Peters9cab5932006-07-28 00:30:00 +0000286- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
287 a memory leak, affecting pickles and deep copies.
288
Tim Petersbc24eee2006-07-27 01:14:53 +0000289- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000290 Paul Eggert.
291
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000292- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
293
Thomas Hellerce049a02006-07-14 17:51:14 +0000294- Patch #1521817: Index range checking on ctypes arrays containing
295 exactly one element enabled again. This allows iterating over these
296 arrays, without the need to check the array size before.
297
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000298- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000299 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000300 /dev/null in certain cases; this is now fixed.
301
Thomas Heller47d7a062006-07-12 08:43:47 +0000302- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
303 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000304
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000305- Because of a misspelled preprocessor symbol, ctypes was always
306 compiled without thread support; this is now fixed.
307
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000308- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
309 methods now allow their database parameter to be None as the
310 sleepycat API allows.
311
Matt Flemingec926502006-07-28 11:27:27 +0000312- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
313 bluetooth API compared with Linux and FreeBSD.

318- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
319 how long the test file should take to play. Now accepts taking 2.93 secs
320 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
321
Georg Brandl4793aa32006-07-28 18:31:39 +0000322- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
323 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
324 run via ``regrtest.py``. Now they do.

333
334- PythonLauncher now works correctly when the path to the script contains
335 characters that are treated specially by the shell (such as quotes).
336
337- Bug #1527397: PythonLauncher now launches scripts with the working directory
338 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000339 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000340 expect.

348Core and builtins
349-----------------
350
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000351- Bug #1441486: The literal representation of -(sys.maxint - 1)
352 again evaluates to a int object, not a long.
353
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000354- Bug #1501934: The scope of global variables that are locally assigned
355 using augmented assignment is now correctly determined.
356
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000357- Bug #927248: Recursive method-wrapper objects can now safely
358 be released.
359
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000360- Bug #1417699: Reject locale-specific decimal point in float()
361 and atof().
362
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000363- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
364 omit a default "error" argument for NULL pointer. This allows
365 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000366
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000367- Bug #1519018: 'as' is now validated properly in import statements.
368
Neal Norwitz28746ab2006-07-09 22:14:42 +0000369- On 64 bit systems, int literals that use less than 64 bits are
370 now ints rather than longs.
371
Neal Norwitzed657552006-07-10 00:04:44 +0000372- Bug #1512814, Fix incorrect lineno's when code at module scope
373 started after line 256.
374
Tim Peters32a83612006-07-10 21:08:24 +0000375- New function ``sys._current_frames()`` returns a dict mapping thread
376 id to topmost thread stack frame. This is for expert use, and is
377 especially useful for debugging application deadlocks. The functionality
378 was previously available in Fazal Majid's ``threadframe`` extension
379 module, but it wasn't possible to do this in a wholly threadsafe way from
380 an extension.

389
Tim Peters32a83612006-07-10 21:08:24 +0000390- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000391 environment variable to be set in order to the SDK environment
392 for finding the compiler, include files, etc.

397
Thomas Woutersadd19112006-07-05 11:03:49 +0000398- string.Template() now correctly handles tuple-values. Previously,
399 multi-value tuples would raise an exception and single-value tuples would
400 be treated as the value they contain, instead.
401
Martin v. Löwisede77f52006-07-03 13:01:35 +0000402- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
403 even if some data are received.

409 degrees and radians.
410
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000411- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000412 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000413
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000414- Bug #1514703: Only setup canvas window in turtle when the canvas
415 is created.
416
Martin v. Löwis7596e832006-07-01 15:33:37 +0000417- Bug #1513223: .close() of a _socketobj now releases the underlying
418 socket again, which then gets closed as it becomes unreferenced.
419
Fred Drake10497c82006-06-29 02:57:48 +0000420- Bug #1504333: Make sgmllib support angle brackets in quoted
421 attribute values.
422
423- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
424 sgmllib ('[' and ']' were not accepted).
425
Georg Brandl1be63af2006-06-28 20:23:25 +0000426- Fix a bug in the turtle module's end_fill function.
427
Brett Cannon53ab5b72006-06-22 16:49:14 +0000428- Bug #1510580: The 'warnings' module improperly required that a Warning
429 category be either a types.ClassType and a subclass of Warning. The proper
430 check is just that it is a subclass with Warning as the documentation states.
431
Georg Brandlad29e632006-06-21 17:45:17 +0000432- The compiler module now correctly compiles the new try-except-finally
433 statement (bug #1509132).
434
Neal Norwitz60373cd2006-06-22 06:30:50 +0000435- The wsgiref package is now installed properly on Unix.
436
Vinay Sajip28e57612006-07-01 10:45:20 +0000437- A bug was fixed in logging.config.fileConfig() which caused a crash on
438 shutdown when fileConfig() was called multiple times.
439
Gerhard Häring762fbd32006-07-02 17:48:30 +0000440- The sqlite3 module did cut off data from the SQLite database at the first
441 null character before sending it to a custom converter. This has been fixed
442 now.
443
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000444Extension Modules
445-----------------
446
Tim Peters112aad32006-07-19 00:03:19 +0000447- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
448 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
449 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000450
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000451- Assigning None to pointer type fields in ctypes structures possible
452 overwrote the wrong fields, this is fixed now.
453
454- Fixed a segfault in _ctypes when ctypes.wintypes were imported
455 on non-Windows platforms.
456
457- Bug #1518190: The ctypes.c_void_p constructor now accepts any
458 integer or long, without range checking.
459
460- Patch #1517790: It is now possible to use custom objects in the ctypes
461 foreign function argtypes sequence as long as they provide a from_param
462 method, no longer is it required that the object is a ctypes type.
463
464- The '_ctypes' extension module now works when Python is configured
465 with the --without-threads option.
466
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000467- Bug #1513646: os.access on Windows now correctly determines write
468 access, again.
469
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000470- Bug #1512695: cPickle.loads could crash if it was interrupted with
471 a KeyboardInterrupt.
472
Neal Norwitza12aa882006-07-06 06:45:08 +0000473- Bug #1296433: parsing XML with a non-default encoding and
474 a CharacterDataHandler could crash the interpreter in pyexpat.

480
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000481- Automate Windows build process for the Win64 SSL module.
482
Tim Peters32a83612006-07-10 21:08:24 +0000483- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000484 Previously, the slight difference could cause compilation errors of the
485 'zlib' module on systems with more than one version of zlib.
486
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000487- The MSI compileall step was fixed to also support a TARGETDIR
488 with spaces in it.
489
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000490- Bug #1517388: sqlite3.dll is now installed on Windows independent
491 of Tcl/Tk.
492
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000493- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000494 trying to be installed even though it's empty.

518Core and builtins
519-----------------
520
Georg Brandla56b9152006-06-19 06:35:54 +0000521- Patch #1507676: Error messages returned by invalid abstract object operations
522 (such as iterating over an integer) have been improved and now include the
523 type of the offending object to help with debugging.
524
Brett Cannonea3912b2006-06-13 21:46:41 +0000525- Bug #992017: A classic class that defined a __coerce__() method that returned
526 its arguments swapped would infinitely recurse and segfault the interpreter.
527
Neal Norwitz909eb122006-06-12 02:13:21 +0000528- Fix the socket tests so they can be run concurrently.
529
Neal Norwitzb9845e72006-06-12 02:11:18 +0000530- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000531 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000532
Brett Cannon22565aa2006-06-09 22:31:23 +0000533- Bug #532646: object.__call__() will continue looking for the __call__
534 attribute on objects until one without one is found. This leads to recursion
535 when you take a class and set its __call__ attribute to an instance of the
536 class. Originally fixed for classic classes, but this fix is for new-style.
537 Removes the infinite_rec_3 crasher.
538
Georg Brandl24250812006-06-09 18:45:48 +0000539- The string and unicode methods startswith() and endswith() now accept
540 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
541
Brett Cannonde3b0522006-06-08 17:00:45 +0000542- Buffer objects, at the C level, never used the char buffer
543 implementation even when the char buffer for the wrapped object was
544 explicitly requested (originally returned the read or write buffer).
545 Now a TypeError is raised if the char buffer is not present but is
546 requested.
547
Georg Brandlddbaa662006-06-04 21:56:52 +0000548- Patch #1346214: Statements like "if 0: suite" are now again optimized
549 away like they were in Python 2.4.
550
Georg Brandlb7c8f542006-05-27 12:30:25 +0000551- Builtin exceptions are now full-blown new-style classes instead of
552 instances pretending to be classes, which speeds up exception handling
553 by about 80% in comparison to 2.5a2.
554
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000555- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
556 Unicode 4.1.
557
Georg Brandlf4ef1162006-05-26 18:03:31 +0000558- Patch #921466: sys.path_importer_cache is now used to cache valid and
559 invalid file paths for the built-in import machinery which leads to
560 fewer open calls on startup.
561
Tim Peters696cf432006-05-24 21:10:40 +0000562- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
563 of-2 bases. The largest speedup is for inputs with about 1000 decimal
564 digits. Conversion from non-power-of-2 bases remains quadratic-time in
565 the number of input digits (it was and remains linear-time for bases
566 2, 4, 8, 16 and 32).
567
Tim Petersb713ec22006-05-23 18:45:30 +0000568- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
569 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
570 an integer close to ``sys.maxint``. This was repaired by patch
571 #1335972, which also gives a nice speedup.
572
Richard Jonescebbefc2006-05-23 18:28:17 +0000573- Patch #1337051: reduced size of frame objects.
574
575- PyErr_NewException now accepts a tuple of base classes as its
576 "base" parameter.
577
Richard Jones7c88dcc2006-05-23 10:37:38 +0000578- Patch #876206: function call speedup by retaining allocated frame
579 objects.
580
Georg Brandl7b90e162006-05-18 07:01:27 +0000581- Bug #1462152: file() now checks more thoroughly for invalid mode
582 strings and removes a possible "U" before passing the mode to the
583 C library function.
584
Neal Norwitz1004a532006-05-15 07:17:23 +0000585- Patch #1488312, Fix memory alignment problem on SPARC in unicode
586
Neal Norwitz373f0a72006-05-15 07:04:36 +0000587- Bug #1487966: Fix SystemError with conditional expression in assignment
588
Martin v. Löwis879768d2006-05-11 13:28:43 +0000589- WindowsError now has two error code attributes: errno, which carries
590 the error values from errno.h, and winerror, which carries the error
591 values from winerror.h. Previous versions put the winerror.h values
592 (from GetLastError()) into the errno attribute.
593
Martin v. Löwis77736712006-05-04 05:51:03 +0000594- Patch #1475845: Raise IndentationError for unexpected indent.
595
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000596- Patch #1479181: split open() and file() from being aliases for each other.
597
Tim Peters44bd9862006-06-01 13:49:23 +0000598- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
599 methods were always silently ignored by dictionaries when comparing keys.
600 They are now passed through (except when using the C API function
601 ``PyDict_GetItem()``, whose semantics did not change).
602
603- Bug #1456209: In some obscure cases it was possible for a class with a
604 custom ``__eq__()`` method to confuse dict internals when class instances
605 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
606 No, you don't have any code that did this ;-)

612
613- Patch #1462338: Upgrade pyexpat to expat 2.0.0
614
Brett Cannon6ee7d012006-06-08 16:23:04 +0000615- Change binascii.hexlify to accept a read-only buffer instead of only a char
616 buffer and actually follow its documentation.
617
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000618- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
619
Nick Coghlanc649ec52006-05-29 12:43:05 +0000620- Patch #1478788 (modified version): The functional extension module has
621 been renamed to _functools and a functools Python wrapper module added.
622 This provides a home for additional function related utilities that are
623 not specifically about functional programming. See PEP 309.
624
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000625- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +0000629- Patch #1435422: zlib's compress and decompress objects now have a
630 copy() method.
631
Andrew MacIntyre92913322006-06-13 15:04:24 +0000632- Patch #1454481: thread stack size is now tunable at runtime for thread
633 enabled builds on Windows and systems with Posix threads support.
634
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000635- On Win32, os.listdir now supports arbitrarily-long Unicode path names
636 (up to the system limit of 32K characters).
637
638- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
639 As a result, these functions now raise WindowsError instead of OSError.
640
Tim Peters7a822da2006-05-25 21:50:17 +0000641- ``time.clock()`` on Win64 should use the high-performance Windows
642 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
643 Windows platforms).
644
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000645- Calling Tk_Init twice is refused if the first call failed as that
646 may deadlock.
647
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000648- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
649 accept it without potentially using an uninitialized pointer.
650
651- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
652 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
653 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000654
Gregory P. Smith372b5832006-06-05 18:48:21 +0000655- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000656 [pybsddb project SF patch number 1466734]
657
Gregory P. Smith372b5832006-06-05 18:48:21 +0000658- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
659 parameter is supplied. [SF pybsddb bug #1477863]
660
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000661- bsddb: the __len__ method of a DB object has been fixed to return correct
662 results. It could previously incorrectly return 0 in some cases.
663 Fixes SF bug 1493322 (pybsddb bug 1184012).
664
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000665- bsddb: the bsddb.dbtables Modify method now raises the proper error and
666 aborts the db transaction safely when a modifier callback fails.
667 Fixes SF python patch/bug #1408584.
668
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000669- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000670 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000671 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
672 database calls that would previously deadlock. [SF python bug #775414]
673
Vinay Sajip28e57612006-07-01 10:45:20 +0000674- Patch #1446489: add support for the ZIP64 extensions to zipfile.

696 mime.types file for determining MIME types.
697
Georg Brandl2605ca82006-06-14 06:08:31 +0000698- Bug #1339007: Shelf objects now don't raise an exception in their
699 __del__ method when initialization failed.
700
Martin v. Löwisd8251432006-06-14 05:21:04 +0000701- Patch #1455898: The MBCS codec now supports the incremental mode for
702 double-byte encodings.
703
Tim Peters43898b42006-06-14 04:09:25 +0000704- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
705 guarantee that adjacent triples in the return list always describe
706 non-adjacent blocks. Previously, a pair of matching blocks could end
707 up being described by multiple adjacent triples that formed a partition
708 of the matching pair.
709
Greg Ward0e0c9f42006-06-11 16:24:11 +0000710- Bug #1498146: fix optparse to handle Unicode strings in option help,
711 description, and epilog.
712
Greg Wardd1c797e2006-06-11 14:42:41 +0000713- Bug #1366250: minor optparse documentation error.

716 clarify docs.
717
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000718- The wsgiref package has been added to the standard library.
719
Nick Coghlan676725d2006-06-08 13:54:49 +0000720- The functions update_wrapper() and wraps() have been added to the functools
721 module. These make it easier to copy relevant metadata from the original
722 function when writing wrapper functions.
723
Tim Petersd6a9eef2006-06-05 01:48:21 +0000724- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
725 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000726
Martin v. Löwis3f767792006-06-04 19:36:28 +0000727- Patch #1359618: Speed up charmap encoder by using a trie structure
728 for lookup.
729
Tim Petersd609b1a2006-06-02 23:22:51 +0000730- The functions in the ``pprint`` module now sort dictionaries by key
731 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
732 if and only if its display required more than one line, although that
733 wasn't documented. The new behavior increases predictability; e.g.,
734 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
735
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000736- Patch #1497027: try HTTP digest auth before basic auth in urllib2

740 default HTTP and HTTPS ports.
741

743
Bob Ippolito7298f272006-05-23 18:43:47 +0000744- Patch #1281707: speed up gzip.readline.
745
Georg Brandlb89316f2006-05-17 15:51:16 +0000746- Patch #1180296: Two new functions were added to the locale module:
747 format_string() to get the effect of "format % items" but locale-aware,
748 and currency() to format a monetary number with currency sign.
749
Georg Brandle3a25832006-05-17 14:56:04 +0000750- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
751 and several features added, such as speed and geometry control.
752

754 tarfiles.
755
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000756- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
757 stdout arguments, making it possible to redirect input and output
758 for remote debugging.
759
760- Patch #1484695: Update the tarfile module to version 0.8. This fixes
761 a couple of issues, notably handling of long file names using the
762 GNU LONGNAME extension.
763
764- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
765 new flag when ``name`` is already the name of an option flag.
766
767- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
768 package.
769

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000806What's New in Python 2.5 alpha 2?
807=================================
808
809*Release date: 27-APR-2006*
810
811Core and builtins
812-----------------
813
Thomas Heller1b046642006-04-18 18:51:06 +0000814- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
815 by converting these apis from macros into exported functions again:
816
817 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
818 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
819 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
820 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
821 PyRun_String Py_CompileString
822
Martin v. Löwis45294a92006-04-18 06:24:08 +0000823- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
824
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000825- All uses of PyStructSequence_InitType have been changed to initialize
826 the type objects only once, even if the interpreter is initialized
827 multiple times.
828
Neal Norwitz61546162006-04-14 05:20:28 +0000829- Bug #1454485, array.array('u') could crash the interpreter. This was
830 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
831 to unicode when it didn't make sense. 'u#' now requires a unicode string.
832
833- Py_UNICODE is unsigned. It was always documented as unsigned, but
834 due to a bug had a signed value in previous versions.
835
Tim Peters3a5e8b12006-04-11 01:44:07 +0000836- Patch #837242: ``id()`` of any Python object always gives a positive
837 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
838 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000839 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000840 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000841
Tim Peters3a5e8b12006-04-11 01:44:07 +0000842 def __hash__(self):
843 return id(self) # WRONG
844
845 because a hash result must be a (short) Python int but it was always
846 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000847 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000848 was always usable as a hash value before this patch. That's no longer
849 necessarily so.
850
851- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000852 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000853 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000854 #1454844)
855
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000856- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
857 involving generators that have paused outside of any ``try`` or ``with``
858 blocks. (In 2.5a1, a paused generator that was part of a reference
859 cycle could not be garbage collected, regardless of whether it was
860 paused in a ``try`` or ``with`` block.)

877 a temporary db (file=None) with the 'n' flag to truncate on open.
878
879- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
880 as older versions cause excessive test failures.

886-------
887
Peter Astrand7d1d4362006-07-14 14:04:45 +0000888- Bug #1223937: subprocess.CalledProcessError reports the exit status
889 of the process using the returncode attribute, instead of
890 abusing errno.
891
Tim Peters711bf302006-04-25 03:31:36 +0000892- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
893 a doctest to be skipped (the code is not run, and the expected output
894 or exception is ignored).
895
Nick Coghlanda2268f2006-04-24 04:37:15 +0000896- Fixed contextlib.nested to cope with exceptions being raised and
897 caught inside exit handlers.
898
Greg Wardab05edc2006-04-23 03:47:58 +0000899- Updated optparse module to Optik 1.5.1 (allow numeric constants in
900 hex, octal, or binary; add ``append_const`` action; keep going if
901 gettext cannot be imported; added ``OptionParser.destroy()`` method;
902 added ``epilog`` for better help generation).
903
Tim Peters21fbd572006-04-21 21:18:10 +0000904- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
905 called from a thread spawned as a side effect of importing a module.
906
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000907- The pydoc module now supports documenting packages contained in
908 .zip or .egg files.
909
910- The pkgutil module now has several new utility functions, such
911 as ``walk_packages()`` to support working with packages that are either
912 in the filesystem or zip files.
913
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000914- The mailbox module can now modify and delete messages from
915 mailboxes, in addition to simply reading them. Thanks to Gregory
916 K. Johnson for writing the code, and to the 2005 Google Summer of
917 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000918
Tim Petersc7605f22006-04-17 21:12:33 +0000919- The ``__del__`` method of class ``local`` in module ``_threading_local``
920 returned before accomplishing any of its intended cleanup.
921

930
Phillip J. Eby47032112006-04-11 01:07:43 +0000931- The warnings, linecache, inspect, traceback, site, and doctest modules
932 were updated to work correctly with modules imported from zipfiles or
933 via other PEP 302 __loader__ objects.
934

946-----
947
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000948- The Makefile now has a reindent target, which runs reindent.py on
949 the library.
950
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000951- Patch #1470875: Building Python with MS Free Compiler
952

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000954
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000955- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
956 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000957 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000958 CXX from --with-cxx-main, see description in README.
959
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000960- Patch #1429775: Link extension modules with the shared libpython.
961
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000962- Fixed a libffi build problem on MIPS systems.
963
Tim Peters8931ff12006-05-13 23:28:20 +0000964- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
965 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
966 and "%zu" for unsigned integers of type ``size_t``.
967
Anthony Baxter51bcb682006-04-05 14:51:42 +0000968Tests
969-----
970
Nick Coghlanda2268f2006-04-24 04:37:15 +0000971- test_contextlib now checks contextlib.nested can cope with exceptions
972 being raised and caught inside exit handlers.
973
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000974- test_cmd_line now checks operation of the -m and -c command switches
975
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000976- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
977 it separately and by hand. It also wasn't cleaning up its changes to
978 the current Decimal context.
979
Thomas Woutersabd08882006-04-26 15:53:30 +0000980- regrtest.py now has a -M option to run tests that test the new limits of
981 containers, on 64-bit architectures. Running these tests is only sensible
982 on 64-bit machines with more than two gigabytes of memory. The argument
983 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000991Documentation
992-------------
993
Tim Petersb06d28c2006-05-12 01:57:59 +0000994- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
995
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000996- PEP 343: Added Context Types section to the library reference
997 and attempted to bring other PEP 343 related documentation into
998 line with the implementation and/or python-dev discussions.
999
Tim Peters8dc73d22006-04-24 02:03:16 +00001000- Bug #1337990: clarified that ``doctest`` does not support examples
1001 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001004What's New in Python 2.5 alpha 1?
1005=================================
1006
Anthony Baxterebed3f62006-04-03 15:03:44 +00001007*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001008
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001009Core and builtins
1010-----------------
1011
Nick Coghlan43832302006-04-23 17:04:07 +00001012- PEP 338: -m command line switch now delegates to runpy.run_module
1013 allowing it to support modules in packages and zipfiles
1014
Martin v. Löwisc661b882006-04-20 04:54:23 +00001015- On Windows, .DLL is not an accepted file name extension for
1016 extension modules anymore; extensions are only found if they
1017 end in .PYD.
1018
Martin v. Löwisea62d252006-04-03 10:56:49 +00001019- Bug #1421664: sys.stderr.encoding is now set to the same value as
1020 sys.stdout.encoding.
1021
Neal Norwitz92e212f2006-04-03 04:48:37 +00001022- __import__ accepts keyword arguments.
1023
Georg Brandlccadf842006-03-31 18:54:53 +00001024- Patch #1460496: round() now accepts keyword arguments.
1025
Anthony Baxter262c00a2006-03-30 10:53:17 +00001026- Fixed bug #1459029 - unicode reprs were double-escaped.
1027
Hye-Shik Changd478f342006-03-23 12:32:36 +00001028- Patch #1396919: The system scope threads are reenabled on FreeBSD
1029 5.4 and later versions.
1030
Neal Norwitze98ccf62006-03-23 05:39:47 +00001031- Bug #1115379: Compiling a Unicode string with an encoding declaration
1032 now gives a SyntaxError.
1033
Georg Brandlabd1ff82006-03-18 07:59:59 +00001034- Previously, Python code had no easy way to access the contents of a
1035 cell object. Now, a ``cell_contents`` attribute has been added
1036 (closes patch #1170323).
1037
Tim Peterscf79aac2006-03-16 01:14:46 +00001038- Patch #1123430: Python's small-object allocator now returns an arena to
1039 the system ``free()`` when all memory within an arena becomes unused
1040 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1041 freed. Some applications will see a drop in virtual memory size now,
1042 especially long-running applications that, from time to time, temporarily
1043 use a large number of small objects. Note that when Python returns an
1044 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001045 platform C library will in turn return that memory to the operating system.
1046 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001047 appears to be effective at least on Microsoft C and gcc-based systems.
1048 Thanks to Evan Jones for hard work and patience.
1049
Georg Brandl533ff6f2006-03-08 18:09:27 +00001050- Patch #1434038: property() now uses the getter's docstring if there is
1051 no "doc" argument given. This makes it possible to legitimately use
1052 property() as a decorator to produce a read-only property.
1053
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001054- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1055 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1056 of requiring an int or long in slicing and a few other contexts, enabling
1057 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1058
Neal Norwitz995acdf2006-03-07 05:01:00 +00001059- Fixed various bugs reported by Coverity's Prevent tool.
1060
Brett Cannonbf364092006-03-01 04:25:17 +00001061- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1062 new exception base class, BaseException, which has a new message attribute.
1063 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1064 Raising a string exception now raises a DeprecationWarning.
1065
Thomas Woutersfb609f42006-02-28 16:37:25 +00001066- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1067 explicitly relative, using 'from .module import name' to mean 'from the same
1068 package as this module is in. Imports without dots still default to the
1069 old relative-then-absolute, unless 'from __future__ import
1070 absolute_import' is used.
1071
Brett Cannona7446e32006-02-27 23:39:10 +00001072- Properly check if 'warnings' raises an exception (usually when a filter set
1073 to "error" is triggered) when raising a warning for raising string
1074 exceptions.
1075
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001076- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001077 The name was removed from Include/code.h.
1078
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001079- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001080
Guido van Rossum1968ad32006-02-25 22:38:04 +00001081- Patch 1433928:
1082 - The copy module now "copies" function objects (as atomic objects).
1083 - dict.__getitem__ now looks for a __missing__ hook before raising
1084 KeyError.
1085
Tim Peters84ef21c2006-02-28 20:39:06 +00001086- PEP 343: with statement implemented. Needs ``from __future__ import
1087 with_statement``. Use of 'with' as a variable will generate a warning.
1088 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001089 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001090 The following objects have __context__ methods:
1091 - The built-in file type.
1092 - The thread.LockType type.
1093 - The following types defined by the threading module:
1094 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1095 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001096
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001097- Fix the encodings package codec search function to only search
1098 inside its own package. Fixes problem reported in patch #1433198.
1099
1100 Note: Codec packages should implement and register their own
1101 codec search function. PEP 100 has the details.
1102
Tim Peters9ea89d22006-06-04 03:26:02 +00001103- PEP 353: Using ``Py_ssize_t`` as the index type.
1104
1105- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1106 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1107 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1108 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1109 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001110
Neal Norwitzfc76d632006-01-10 06:03:13 +00001111- Patch #1400181, fix unicode string formatting to not use the locale.
1112 This is how string objects work. u'%f' could use , instead of .
1113 for the decimal point. Now both strings and unicode always use periods.
1114
Neal Norwitz671b9e32006-01-09 07:07:12 +00001115- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1116 configure would break checking curses.h.
1117
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001118- Bug #959576: The pwd module is now builtin. This allows Python to be
1119 built on UNIX platforms without $HOME set.
1120
Neal Norwitzc10978f2005-12-19 06:07:16 +00001121- Bug #1072182, fix some potential problems if characters are signed.
1122
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001123- Bug #889500, fix line number on SyntaxWarning for global declarations.
1124
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001125- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1126
Neal Norwitze7214a12005-12-18 05:03:17 +00001127- Support for converting hex strings to floats no longer works.
1128 This was not portable. float('0x3') now raises a ValueError.
1129
Barry Warsaw2a38a862005-12-18 01:27:35 +00001130- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001131 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001132 is now displayed in interactive prompt banner.
1133
Georg Brandlfa166682005-12-17 21:45:17 +00001134- Implementation of PEP 341 - Unification of try/except and try/finally.
1135 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001136 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001137
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001138- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1139 now encodes backslash correctly.
1140
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001141- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1142
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001143- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001144 and long longs.
1145
Neal Norwitz67715f02005-11-09 06:59:35 +00001146- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001147 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001148 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001149
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001150- Replaced most Unicode charmap codecs with new ones using the
1151 new Unicode translate string feature in the builtin charmap
1152 codec; the codecs were created from the mapping tables available
1153 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1154 encodings now include a mapping for the Apple logo)
1155
Tim Peterse3547fd2005-12-16 23:13:57 +00001156- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001157
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001158- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001159
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001160- A new AST parser implementation was completed. The abstract
1161 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001162 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001163
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001164- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001165 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1166
Neal Norwitz708e51a2005-10-03 04:48:15 +00001167- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1168
Neal Norwitz11bd1192005-10-03 00:54:56 +00001169- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1170 Provide a warning when a directory is passed on the command line.
1171
Neal Norwitz40d37812005-10-02 01:48:49 +00001172- Fix segfault with invalid coding.
1173
1174- SF bug #772896: unknown encoding results in MemoryError.
1175
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001176- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001177 supported a __len__() method which evaluated to False when the iterator
1178 was empty.
1179
Guido van Rossum630db602005-09-20 18:49:54 +00001180- On 64-bit platforms, when __len__() returns a value that cannot be
1181 represented as a C int, raise OverflowError.
1182
Skip Montanarof8948ca2005-09-19 03:54:46 +00001183- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001184 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001185
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001186- SF bug #893549: parsing keyword arguments was broken with a few format
1187 codes.
1188
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001189- Changes donated by Elemental Security to make it work on AIX 5.3
1190 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1191 bug #105470: test_pwd fails on 64bit system (Opteron).
1192
Guido van Rossum539c6622005-09-14 17:49:54 +00001193- Changes donated by Elemental Security to make it work on HP-UX 11 on
1194 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1195
Georg Brandl4550b8d2005-08-26 06:43:52 +00001196- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001197 (fixes bug #1119418).
1198
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001199- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1200
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001201- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1202 exceptions that cause a function to exit.
1203
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001204- The implementation of set() and frozenset() was revised to use its
1205 own internal data structure. Memory consumption is reduced by 1/3
1206 and there are modest speed-ups as well. The API is unchanged.
1207
Tim Petersde7990b2005-07-17 23:45:23 +00001208- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1209
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001210- SF bug #1229429: PyObject_CallMethod failed to decrement some
1211 reference counts in some error exit cases.
1212
Tim Petersecc6e6a2005-07-10 22:30:55 +00001213- SF bug #1185883: Python's small-object memory allocator took over
1214 a block managed by the platform C library whenever a realloc specified
1215 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001216 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001217 portable way to copy data from the C-managed block into Python's
1218 small-object space without risking a memory fault. Python's small-object
1219 realloc now leaves such blocks under the control of the platform C
1220 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00001222- SF bug #1232517: An overflow error was not detected properly when
1223 attempting to convert a large float to an int in os.utime().
1224
Raymond Hettinger3296e692005-06-29 23:29:56 +00001225- SF bug #1224347: hex longs now print with lowercase letters just
1226 like their int counterparts.
1227
Michael W. Hudson188d4362005-06-20 16:52:57 +00001228- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1229 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1230 interpreter states; back out that fix and do a better job (see
1231 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1232 for a longer write-up of the problem).
1233
Michael W. Hudsondf888462005-06-03 14:41:55 +00001234- SF patch #1180995: marshal now uses a binary format by default when
1235 serializing floats.
1236
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001237- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1238 the routines that promise to produce IEEE 754 binary representations
1239 of floats now simply copy bytes around.
1240
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001241- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1242 278.
1243
Brett Cannonc3647ac2005-04-26 03:45:26 +00001244- patch #1109424: int, long, float, complex, and unicode now check for the
1245 proper magic slot for type conversions when subclassed. Previously the
1246 magic slot was ignored during conversion. Semantics now match the way
1247 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001248 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001249 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001250 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001251
Barry Warsawc8d907c2005-04-19 23:43:40 +00001252- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1253 NULL, now raise an AttributeError when attempting to set or delete the
1254 attribute. Previously a TypeError was raised, but this was inconsistent
1255 with the equivalent pure-Python implementation.
1256
Michael W. Hudson774479c2005-04-18 08:46:17 +00001257- It is now safe to call PyGILState_Release() before
1258 PyEval_InitThreads() (note that if there is reason to believe there
1259 are multiple threads around you still must call PyEval_InitThreads()
1260 before using the Python API; this fix is for extension modules that
1261 have no way of knowing if Python is multi-threaded yet).
1262
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001263- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1264 disabled caused a crash.
1265
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001266- Bug #1165306: instancemethod_new allowed the creation of a method
1267 with im_class == im_self == NULL, which caused a crash when called.
1268
Tim Petersecc6e6a2005-07-10 22:30:55 +00001269- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001270 fixes the crash seen in bug #1165761
1271
Raymond Hettinger96229b12005-03-11 06:49:40 +00001272- Added two new builtins, any() and all().
1273
Brett Cannon409d8f22005-03-05 06:47:57 +00001274- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001275 (e.g., ``class C(): pass`` is no longer a syntax error).
1276 Patch #1176012 added support to the 'parser' module and 'compiler' package
1277 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001278
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001279- Patch #1115086: Support PY_LONGLONG in structmember.
1280
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001281- Bug #1155938: new style classes did not check that __init__() was
1282 returning None.
1283
Tim Petersecc6e6a2005-07-10 22:30:55 +00001284- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001285 ('\') with a specific error message.
1286
Martin v. Löwisff232d72005-03-03 09:24:38 +00001287- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1288
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001289- Bug #1124295: the __name__ attribute of file objects was
1290 inadvertently made inaccessible in restricted mode.
1291
Tim Petersecc6e6a2005-07-10 22:30:55 +00001292- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001293 an ferror() call.
1294
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001295- min() and max() now support key= arguments with the same meaning as in
1296 list.sort().
1297
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001298- The peephole optimizer now performs simple constant folding in expressions:
1299 (2+3) --> (5).
1300
Raymond Hettingera422c342005-01-11 03:03:27 +00001301- set and frozenset objects can now be marshalled. SF #1098985.
1302
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001303- Bug #1077106: Poor argument checking could cause memory corruption
1304 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001305
Jeremy Hyltonab630502005-02-04 18:44:06 +00001306- The parser did not complain about future statements in illegal
1307 positions. It once again reports a syntax error if a future
1308 statement occurs after anything other than a doc string.
1309
Neil Schemenauercf52c072005-08-12 17:34:58 +00001310- Change the %s format specifier for str objects so that it returns a
1311 unicode instance if the argument is not an instance of basestring and
1312 calling __str__ on the argument returns a unicode instance.
1313
Tim Petersf4e69282006-02-27 17:15:31 +00001314- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1315 current thread state when the auto-GIL-state machinery knows about
1316 it (since the thread state is being deleted, continuing to remember it
1317 can't help, but can hurt if another thread happens to get created with
1318 the same thread id).
1319
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001320Extension Modules

Neal Norwitz10be10c2006-03-16 06:50:13 +00001336 util, whatsound, whrandom, zmod
1337
1338- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1339
1340- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001341 is deprecated. The undocumented re.engine variable no longer exists.
1342

1345
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001346- The unicodedata module was updated to the 4.1 version of the Unicode
1347 database. The 3.2 version is still available as unicodedata.db_3_2_0
1348 for applications that require this specific version (such as IDNA).
1349
Neal Norwitzb62c4332006-03-04 18:35:47 +00001350- The timing module is no longer built by default. It was deprecated
1351 in PEP 4 in Python 2.0 or earlier.
1352
Guido van Rossum1968ad32006-02-25 22:38:04 +00001353- Patch 1433928: Added a new type, defaultdict, to the collections module.
1354 This uses the new __missing__ hook behavior added to dict (see above).
1355
Georg Brandldbd83392006-02-20 09:42:33 +00001356- Bug #854823: socketmodule now builds on Sun platforms even when

1371
Martin v. Löwis14694662006-02-03 12:54:16 +00001372- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1373 are reported, the limit on path name lengths is removed, and stat reports
1374 WindowsError now (instead of OSError).
1375
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001376- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

1451 the request code argument, which results in more C-like behaviour
1452 for large or negative values.
1453
Tim Petersecc6e6a2005-07-10 22:30:55 +00001454- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1496
Raymond Hettingerb2594052004-12-05 09:25:51 +00001497- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001510- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1511 been renamed to have only a single underscore prefix. This was done to
1512 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001513
Nick Coghlan43832302006-04-23 17:04:07 +00001514- PEP 338: new module runpy defines a run_module function to support
1515 executing modules which provide access to source code or a code object
1516 via the PEP 302 import mechanisms.
1517
Anthony Baxter93f5b932006-04-03 08:05:07 +00001518- The email module's parsedate_tz function now sets the daylight savings

1526 in attribute values.
1527
Anthony Baxterc51ee692006-04-01 00:57:31 +00001528- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001529 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001530 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001531 module will not be built.
1532
Tim Petersc17976e2006-04-01 00:26:53 +00001533- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1534 aren't officially supported here, and trying to use them will probably
1535 raise an exception some day. But dicts have been allowed, and "mostly
1536 worked", so support for them won't go away without warning.
1537
Georg Brandl338ef7d2006-03-31 18:42:16 +00001538- Bug #1445068: getpass.getpass() can now be given an explicit stream
1539 argument to specify where to write the prompt.
1540

1550 to make it easier to monitor when daemon threads have completed
1551 processing all enqueued tasks. Patch #1455676.
1552
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001553- popen2.Popen objects now preserve the command in a .cmd attribute.

1556
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001557- email 4.0 package now integrated. This is largely the same as the email 3.0
1558 package that was included in Python 2.3, except that PEP 8 module names are
1559 now used (e.g. mail.message instead of email.Message). The MIME classes
1560 have been moved to a subpackage (e.g. email.mime.text instead of
1561 email.MIMEText). The old names are still supported for now. Several
1562 deprecated Message methods have been removed and lots of bugs have been
1563 fixed. More details can be found in the email package documentation.
1564
Walter Dörwald40108c92006-03-27 08:15:44 +00001565- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1566 (a subclass of tuple) that provides incremental decoders and encoders
1567 (a way to use stateful codecs without the stream API). Python functions
1568 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1569 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1570 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001571
Walter Dörwald067db482006-03-15 22:17:27 +00001572- Patch #1359365: Calling next() on a closed StringIO.String object raises
1573 a ValueError instead of a StopIteration now (like file and cString.String do).
1574 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1575 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001576
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001577- A regrtest option -w was added to re-run failed tests in verbose mode.

1650 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1651 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1652 Ronald L. Rivest offered this advice for Python:
1653
1654 "The consensus of researchers in this area (at least as
1655 expressed at the NIST Hash Function Workshop 10/31/05),
1656 is that SHA-256 is a good choice for the time being, but
1657 that research should continue, and other alternatives may
1658 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001659
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001660- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00001744
Georg Brandl2f210b62005-06-26 22:09:06 +00001745- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
1746
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001747- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1748 error messages.
1749
Georg Brandl379f99d2005-06-26 21:09:38 +00001750- Bug #1108948: Cookie.py produced invalid JavaScript code.
1751
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001752- The tokenize module now detects and reports indentation errors.
1753 Bug #1224621.
1754
Raymond Hettinger68c04532005-06-10 11:05:19 +00001755- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001756 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001757 the generate_tokens() function now accepts a callable argument that
1758 terminates by raising StopIteration.
1759
Georg Brandl9166e1a2005-06-04 09:20:03 +00001760- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1761
Georg Brandl268e61c2005-06-03 14:28:50 +00001762- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1763 component of the path.
1764
Skip Montanaro174dd222005-05-14 20:54:16 +00001765- Patch #1120353: The xmlrpclib module provides better, more transparent,
1766 support for datetime.{datetime,date,time} objects. With use_datetime set
1767 to True, applications shouldn't have to fiddle with the DateTime wrapper
1768 class at all.
1769
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001770- distutils.commands.upload was added to support uploading distribution
1771 files to PyPI.
1772
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001773- distutils.commands.register now encodes the data as UTF-8 before posting
1774 them to PyPI.
1775
Raymond Hettinger267b8682005-03-27 10:47:39 +00001776- decimal operator and comparison methods now return NotImplemented
1777 instead of raising a TypeError when interacting with other types. This
1778 allows other classes to implement __radd__ style methods and have them
1779 work as expected.
1780
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001781- Bug #1163325: Decimal infinities failed to hash. Attempting to
1782 hash a NaN raised an InvalidOperation instead of a TypeError.
1783
Tim Petersecc6e6a2005-07-10 22:30:55 +00001784- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001785 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1786
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001787- Patch #1043890: Add extractall method to tarfile.

1790 to build.
1791
Martin v. Löwis637431b2005-03-03 23:12:42 +00001792- Patch #1103407: Properly deal with tarfile iterators when untarring
1793 symbolic links on Windows.

Martin v. Löwisa4dac402005-03-03 11:39:45 +00001796 profile.py if available.
1797
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001798- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1799

1816
Raymond Hettingerbab41432005-02-05 01:31:19 +00001817- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1818
Guido van Rossumd0641422005-02-03 15:01:24 +00001819- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1820 disables recursive traversal through instance attributes, which can
1821 be exploited in various ways.
1822
Tim Peterse3547fd2005-12-16 23:13:57 +00001823- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001824 flags on the HTTP listening socket.
1825
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001826- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1827 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1828
Fred Drakefbdeaad2006-07-29 16:56:15 +00001829- Patches #893642, #1039083: add allow_none, encoding arguments to
1830 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001831
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001832- Bug #1110478: Revert os.environ.update to do putenv again.
1833
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001834- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1835
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001836- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1837
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001838- Enhancements to the csv module:
1839
1840 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001841 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001842 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001843 + Dialect parameter parsing has been re-implemented to improve error
1844 reporting.
1845 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1846 dictates.
1847 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001848 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001849 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001850 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1851 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001852 + reader now allows \r characters to be quoted (previously it only allowed
1853 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001854 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001855 + Dialect classes passed to the module are no longer instantiated by
1856 the module before being parsed (the former validation scheme required
1857 this, but the mechanism was unreliable).
1858 + The dialect registry now contains instances of the internal
1859 C-coded dialect type, rather than references to python objects.
1860 + the internal c-coded dialect type is now immutable.
1861 + register_dialect now accepts the same keyword dialect specifications
1862 as the reader and writer, allowing the user to register dialects
1863 without first creating a dialect class.
1864 + a configurable limit to the size of parsed fields has been added -
1865 previously, an unmatched quote character could result in the entire
1866 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001867 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001868 the parser field size limit (returning the former limit). The initial
1869 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001870 + A line_num attribute has been added to the reader object, which tracks
1871 the number of lines read from the source iterator. This is not
1872 the same as the number of records returned, as records can span
1873 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001874 + reader and writer objects were not being registered with the cyclic-GC.
1875 This has been fixed.
1876
Brett Cannone6539c42005-01-08 02:43:53 +00001877- _DummyThread objects in the threading module now delete self.__block that is
1878 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1879 lock primitives tend to be limited in number and thus should not be wasted on
1880 a _DummyThread object. Fixes bug #1089632.
1881
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001882- The imghdr module now detects Exif files.
1883
Raymond Hettinger6065d322004-12-20 23:51:53 +00001884- StringIO.truncate() now correctly adjusts the size attribute.
1885 (Bug #951915).
1886
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001887- locale.py now uses an updated locale alias table (built using
1888 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1889 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001890 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001891
Raymond Hettinger3557f422004-12-07 12:02:02 +00001892- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1893
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001894- the pickle module no longer accepts the deprecated None option in the
1895 args tuple returned by __reduce__().
1896
Brett Cannon84667c02004-12-07 03:25:18 +00001897- optparse now optionally imports gettext. This allows its use in setup.py.
1898
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001899- the pickle module no longer uses the deprecated bin parameter.
1900
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001901- the shelve module no longer uses the deprecated binary parameter.
1902
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001903- the pstats module no longer uses the deprecated ignore() method.
1904
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001905- the filecmp module no longer uses the deprecated use_statcache argument.
1906
Raymond Hettinger664347b2004-12-04 21:21:53 +00001907- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1908 extended or overridden by subclasses. Formerly, the subclassed method would
1909 be ignored by the rest of the module. (Bug #1078905).
1910
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001911- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001912 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001913
Walter Dörwald36733692004-12-22 12:50:50 +00001914- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1915 once when a size argument is given. This prevents a buffer overflow in the
1916 tokenizer with very long source lines.
1917
Barry Warsaw538561e2006-01-01 21:48:54 +00001918- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1919 immediately after creating the object, without any intervening
1920 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001921
Skip Montanaro05885812005-01-16 20:48:27 +00001922- The reconvert.quote function can now emit triple-quoted strings. The
1923 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001924
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001925- ``UserString.MutableString`` now supports negative indices in
1926 ``__setitem__`` and ``__delitem__``
1927
Greg Ward40407942005-03-05 02:53:17 +00001928- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1929 correctly.
1930
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001931- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1932 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1933 character even if the user has passed a size parameter to get a proper
1934 line ending. Remove the special handling of a "\r\n" that has been split
1935 between two lines.
1936
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001937- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1938 about illegal code points. The codec now supports PEP 293 style error
1939 handlers.
1940
Walter Dörwald78a78b02005-09-01 12:04:29 +00001941- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001942 from the input stream, so that the output is a byte string in the correct
1943 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001944
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001945- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1946 considering it exactly like a '*'.
1947
Walter Dörwald007f8df2005-10-09 19:42:27 +00001948- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1949 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001950
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001951- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1952
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001953- Patch #1413711: Certain patterns of differences were making difflib
1954 touch the recursion limit.
1955
Walter Dörwald58917a62006-03-31 15:26:22 +00001956- Bug #947906: An object oriented interface has been added to the calendar
1957 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001958 called as a script (e.g. via ``python -mcalendar``). Localized month and
1959 weekday names can be ouput (even if an exotic encoding is used) using
1960 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001961

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001976- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1977 The zlib module is now builtin on Windows.
1978
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001979- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1980
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001981- Bug #1189330: configure did not correctly determine the necessary
1982 value of LINKCC if python was built with GCC 4.0.
1983
Trent Mick8321b422005-07-26 02:29:21 +00001984- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1985 vulnerability in zlib 1.2.1 and 1.2.2.
1986
Brett Cannon08cd5982005-04-24 22:26:38 +00001987- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1988 flags that change binary compatibility. Changes were also made to
1989 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001990 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001991
Bob Ippolitoed233462005-03-29 13:47:59 +00001992- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1993 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1994 no longer exists). This configure patch makes things right.
1995
Martin v. Löwise2713be2005-03-08 15:03:08 +00001996- Bug #1158607: Build with --disable-unicode again.
1997
Brett Cannon46d96232005-02-16 00:07:19 +00001998- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1999 defined. Discovered as a result of not being able to build on OS X.
2000
Brett Cannon516592f2004-12-07 00:42:59 +00002001- setup.py now uses the directories specified in LDFLAGS using the -L option
2002 and in CPPFLAGS using the -I option for adding library and include
2003 directories, respectively, for compiling extension modules against. This has
2004 led to the core being compiled using the values in CPPFLAGS. It also removes
2005 the need for the special-casing of both DarwinPorts and Fink for darwin since
2006 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2007 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2008 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00002010- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2011 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2012 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2013 Closes bug #1096244. Thanks Gregory Bond.

2016-----
2017
Tim Petersc9d78aa2006-03-26 23:27:58 +00002018- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2019 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2020 is obtained via the ``PyObject_`` family, it must be released via the
2021 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2022 always been officially true, but when Python's small-object allocator was
2023 introduced, an attempt was made to cater to a few extension modules
2024 discovered at the time that obtained memory via ``PyObject_New`` but
2025 released it via ``PyMem_DEL``. It's years later, and if such code still
2026 exists it will fail now (probably with segfaults, but calling wrong
2027 low-level memory management functions can yield many symptoms).
2028
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002029- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002033- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2034 mapping argument now. This string is used as a mapping table. Byte values
2035 greater than the length of the string and 0xFFFE are treated as undefined
2036 mappings.
