Marc-André Lemburg040f76b2006-08-14 10:55:19 +000015- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000016 compared equal or unequal to a string and a UnicodeDecodeError
17 exception occurs, 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
Marc-André Lemburg574cfea2006-08-16 16:11:01 +000067- The distutils version has been changed to 2.5.0. The change to
68 keep it programmatically in sync with the Python version running
69 the code (introduced in 2.5b3) has been reverted. It will continue
70 to be maintained manually as static string literal.
71
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +000072- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +000073 and this cannot be converted to the required C type, an exception is
74 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +000075 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +000076
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000077- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +000078 an exception.
79
Anthony Baxter58179592006-08-16 13:08:25 +000080- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000081 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +000082 workarounds for clocks with low resolution, to stop the code yielding
83 duplicate UUIDs.
84
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +000085- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
86 before raising SystemExit, allowing IDLE to honor quit() and exit().
87
Neal Norwitzbf8c1952006-08-15 04:14:57 +000088- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
89
Georg Brandl7a1af772006-08-14 21:55:28 +000090- Patch #1536071: trace.py should now find the full module name of a
91 file correctly even on Windows.
92
Georg Brandl0a7d1bb2006-08-11 07:26:10 +000093- logging's atexit hook now runs even if the rest of the module has
94 already been cleaned up.
95
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000096- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +000097
Neal Norwitzff4b63b2006-08-04 04:50:21 +000098- Bug #1531405, format_exception no longer raises an exception if
99 str(exception) raised an exception.
100
Neil Schemenauer06ded092006-08-04 16:20:30 +0000101- Fix a bug in the ``compiler`` package that caused invalid code to be
102 generated for nested functions.
103
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000104

Neal Norwitzbf8c1952006-08-15 04:14:57 +0000108- Patch #1511317: don't crash on invalid hostname (alias) info.
109
Georg Brandl3335a7a2006-08-14 21:42:55 +0000110- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
111 raises the correct exceptions.
112
Thomas Heller1ce433e2006-08-14 16:20:04 +0000113- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
114 '-no-stack-protector' compiler flag for OpenBSD has been removed.
115
Thomas Heller86720042006-08-14 11:17:48 +0000116- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
117 uses the _as_parameter_ attribute when objects are passed to foreign
118 function calls. The ctypes version number was changed to 1.0.1.
119
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000120- Bug #1530559, struct.pack raises TypeError where it used to convert.
121 Passing float arguments to struct.pack when integers are expected
122 now triggers a DeprecationWarning.
123
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000124

146-----
147
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000148- Bug #1535502, build _hashlib on Windows, and use masm assembler
149 code in OpenSSL.
150
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000151- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Fred Drake53912162006-07-29 13:22:49 +0000171What's New in Python 2.5 beta 3?
172================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000173
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000174*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000175
176Core and builtins
177-----------------
178
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000179- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000180 returned a long (see PEP 353).
181
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000182- Bug #1515471: string.replace() accepts character buffers again.
183
Neal Norwitz07aadb12006-07-30 06:55:48 +0000184- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
185 This provides the proper warning for struct.pack().
186 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
187
Neal Norwitz0d62a062006-07-30 06:53:31 +0000188- Patch #1531113: Fix augmented assignment with yield expressions.
189 Also fix a SystemError when trying to assign to yield expressions.
190
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000191- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
192 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
193 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
194 excessive filesystem operations during imports.
195
Tim Petersbc24eee2006-07-27 01:14:53 +0000196- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
197 operations on signed longs that are formally undefined by C.
198 Unfortunately, at least one compiler now cares about that, so complicated
199 the code to make that compiler happy again.
200
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000201- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
202
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000203- Patch #1232023: Stop including current directory in search
204 path on Windows.
205
Neal Norwitze1fdb322006-07-21 05:32:28 +0000206- Fix some potential crashes found with failmalloc.
207
Neal Norwitze7563102006-07-17 01:00:16 +0000208- Fix warnings reported by Klocwork's static analysis tool.
209
Neal Norwitz84be93b2006-07-16 01:50:38 +0000210- Bug #1512814, Fix incorrect lineno's when code within a function
211 had more than 255 blank lines.
212
Georg Brandl9dceedb2006-07-12 15:31:17 +0000213- Patch #1521179: Python now accepts the standard options ``--help`` and
214 ``--version`` as well as ``/?`` on Windows.
215
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000216- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000217 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000218 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000219
Tim Peters112aad32006-07-19 00:03:19 +0000220- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000221 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000222 new ``sys._current_frames()`` returns a dictionary with one entry,
223 mapping the faux "thread id" 0 to the current frame.
224
Ronald Oussoren3075e162006-07-25 20:28:55 +0000225- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000226
Ronald Oussoren3075e162006-07-25 20:28:55 +0000227
Neal Norwitza1f10902006-07-12 07:28:29 +0000228Library
229-------
230
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000231- Correction of patch #1455898: In the mbcs decoder, set final=False
232 for stream decoder, but final=True for the decode function.
233
Georg Brandl07fec3a2006-08-01 18:49:24 +0000234- os.urandom no longer masks unrelated exceptions like SystemExit or
235 KeyboardInterrupt.
236
Tim Peters4643c2f2006-08-10 22:45:34 +0000237- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000238 shutil.copytree on Windows
239
Georg Brandle34ac7c2006-07-30 11:07:23 +0000240- Bug #1002398: The documentation for os.path.sameopenfile now correctly
241 refers to file descriptors, not file objects.
242
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000243- The renaming of the xml package to xmlcore, and the import hackery done
244 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000245 #1513611, and probably others.
246
Georg Brandledd9b0d2006-07-29 09:33:26 +0000247- Bug #1441397: The compiler module now recognizes module and function
248 docstrings correctly as it did in Python 2.4.
249
Tim Peters6f681472006-07-27 23:44:37 +0000250- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
251 lost that tests are sorted by name before being run. This rarely
252 matters for well-written tests, but can create baffling symptoms if
253 side effects from one test to the next affect outcomes. ``DocTestFinder``
254 has been changed to sort the list of tests it returns.
255
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000256- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000257 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000258
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000259- Bug #978833: Really close underlying socket in _socketobject.close.
260
Georg Brandl0619a322006-07-26 07:40:17 +0000261- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
262 with title().
263
Georg Brandlcf0c1722006-07-26 07:23:32 +0000264- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
265 to recursive calls and call it with the failing package name.
266
Martin v. Löwis0b483032006-07-25 09:53:12 +0000267- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
268
Georg Brandlc13c34c2006-07-24 14:09:56 +0000269- Patch #1515343: Fix printing of deprecated string exceptions with a
270 value in the traceback module.
271
Greg Ward48fae7a2006-07-23 16:05:51 +0000272- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
273
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000274- Patch #1524429: Use repr() instead of backticks in Tkinter again.
275
Brett Cannoncaebe222006-07-18 04:41:36 +0000276- Bug #1520914: Change time.strftime() to accept a zero for any position in its
277 argument tuple. For arguments where zero is illegal, the value is forced to
278 the minimum value that is correct. This is to support an undocumented but
279 common way people used to fill in inconsequential information in the time
280 tuple pre-2.4.
281
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000282- Patch #1220874: Update the binhex module for Mach-O.
283
Barry Warsawb110bad2006-07-21 14:51:07 +0000284- The email package has improved RFC 2231 support, specifically for
285 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
286 (name*0=<blah>) parameter continuations. This may change the types of
287 values returned from email.message.Message.get_param() and friends.
288 Specifically in some cases where non-encoded continuations were used,
289 get_param() used to return a 3-tuple of (None, None, string) whereas now it
290 will just return the string (since non-encoded continuations don't have
291 charset and language parts).
292
293 Also, whereas % values were decoded in all parameter continuations, they are
294 now only decoded in encoded parameter parts.
295
Ronald Oussoren3075e162006-07-25 20:28:55 +0000296- Bug #1517990: IDLE keybindings on MacOS X now work correctly
297
298- Bug #1517996: IDLE now longer shows the default Tk menu when a
299 path browser, class browser or debugger is the frontmost window on MacOS X
300
Barry Warsaw00decd72006-07-27 23:43:15 +0000301- Patch #1520294: Support for getset and member descriptors in types.py,
302 inspect.py, and pydoc.py. Specifically, this allows for querying the type
303 of an object against these built-in types and more importantly, for getting
304 their docstrings printed in the interactive interpreter's help() function.

308-----------------
309
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000310- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
311 a socket operation on a socket with a timeout, the exception will be
312 caught correctly. Previously, the exception was not caught.
313
Thomas Heller1393d6a2006-07-28 21:43:20 +0000314- Patch #1529514: The _ctypes extension is now compiled on more
315 openbsd target platforms.
316
Tim Peters9cab5932006-07-28 00:30:00 +0000317- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
318 a memory leak, affecting pickles and deep copies.
319
Tim Petersbc24eee2006-07-27 01:14:53 +0000320- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

324
Thomas Hellerce049a02006-07-14 17:51:14 +0000325- Patch #1521817: Index range checking on ctypes arrays containing
326 exactly one element enabled again. This allows iterating over these
327 arrays, without the need to check the array size before.
328
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000329- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000330 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000331 /dev/null in certain cases; this is now fixed.
332
Thomas Heller47d7a062006-07-12 08:43:47 +0000333- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
334 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000335
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000336- Because of a misspelled preprocessor symbol, ctypes was always
337 compiled without thread support; this is now fixed.
338
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000339- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
340 methods now allow their database parameter to be None as the
341 sleepycat API allows.
342
Matt Flemingec926502006-07-28 11:27:27 +0000343- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
344 bluetooth API compared with Linux and FreeBSD.
345
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000346Tests
347-----
348
349- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
350 how long the test file should take to play. Now accepts taking 2.93 secs
351 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
352
Georg Brandl4793aa32006-07-28 18:31:39 +0000353- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
354 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
355 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000362Mac
363---
364
365- PythonLauncher now works correctly when the path to the script contains
366 characters that are treated specially by the shell (such as quotes).
367
368- Bug #1527397: PythonLauncher now launches scripts with the working directory
369 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000370 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000371 expect.

379Core and builtins
380-----------------
381
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000382- Bug #1441486: The literal representation of -(sys.maxint - 1)
383 again evaluates to a int object, not a long.
384
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000385- Bug #1501934: The scope of global variables that are locally assigned
386 using augmented assignment is now correctly determined.
387
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000388- Bug #927248: Recursive method-wrapper objects can now safely
389 be released.
390
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000391- Bug #1417699: Reject locale-specific decimal point in float()
392 and atof().
393
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000394- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
395 omit a default "error" argument for NULL pointer. This allows
396 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000397
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000398- Bug #1519018: 'as' is now validated properly in import statements.
399
Neal Norwitz28746ab2006-07-09 22:14:42 +0000400- On 64 bit systems, int literals that use less than 64 bits are
401 now ints rather than longs.
402
Neal Norwitzed657552006-07-10 00:04:44 +0000403- Bug #1512814, Fix incorrect lineno's when code at module scope
404 started after line 256.
405
Tim Peters32a83612006-07-10 21:08:24 +0000406- New function ``sys._current_frames()`` returns a dict mapping thread
407 id to topmost thread stack frame. This is for expert use, and is
408 especially useful for debugging application deadlocks. The functionality
409 was previously available in Fazal Majid's ``threadframe`` extension
410 module, but it wasn't possible to do this in a wholly threadsafe way from
411 an extension.

420
Tim Peters32a83612006-07-10 21:08:24 +0000421- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000422 environment variable to be set in order to the SDK environment
423 for finding the compiler, include files, etc.

428
Thomas Woutersadd19112006-07-05 11:03:49 +0000429- string.Template() now correctly handles tuple-values. Previously,
430 multi-value tuples would raise an exception and single-value tuples would
431 be treated as the value they contain, instead.
432
Martin v. Löwisede77f52006-07-03 13:01:35 +0000433- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
434 even if some data are received.
435
Martin v. Löwis45482392006-07-03 12:28:58 +0000436- Bug #1267547: Put proper recursive setup.py call into the
437 spec file generated by bdist_rpm.

440 degrees and radians.
441
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000442- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000443 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000444
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000445- Bug #1514703: Only setup canvas window in turtle when the canvas
446 is created.
447
Martin v. Löwis7596e832006-07-01 15:33:37 +0000448- Bug #1513223: .close() of a _socketobj now releases the underlying
449 socket again, which then gets closed as it becomes unreferenced.
450
Fred Drake10497c82006-06-29 02:57:48 +0000451- Bug #1504333: Make sgmllib support angle brackets in quoted
452 attribute values.
453
454- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
455 sgmllib ('[' and ']' were not accepted).
456
Georg Brandl1be63af2006-06-28 20:23:25 +0000457- Fix a bug in the turtle module's end_fill function.
458
Brett Cannon53ab5b72006-06-22 16:49:14 +0000459- Bug #1510580: The 'warnings' module improperly required that a Warning
460 category be either a types.ClassType and a subclass of Warning. The proper
461 check is just that it is a subclass with Warning as the documentation states.
462
Georg Brandlad29e632006-06-21 17:45:17 +0000463- The compiler module now correctly compiles the new try-except-finally
464 statement (bug #1509132).
465
Neal Norwitz60373cd2006-06-22 06:30:50 +0000466- The wsgiref package is now installed properly on Unix.
467
Vinay Sajip28e57612006-07-01 10:45:20 +0000468- A bug was fixed in logging.config.fileConfig() which caused a crash on
469 shutdown when fileConfig() was called multiple times.
470
Gerhard Häring762fbd32006-07-02 17:48:30 +0000471- The sqlite3 module did cut off data from the SQLite database at the first
472 null character before sending it to a custom converter. This has been fixed
473 now.
474

476-----------------
477
Tim Peters112aad32006-07-19 00:03:19 +0000478- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
479 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
480 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000481
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000482- Assigning None to pointer type fields in ctypes structures possible
483 overwrote the wrong fields, this is fixed now.
484
485- Fixed a segfault in _ctypes when ctypes.wintypes were imported
486 on non-Windows platforms.
487
488- Bug #1518190: The ctypes.c_void_p constructor now accepts any
489 integer or long, without range checking.
490
491- Patch #1517790: It is now possible to use custom objects in the ctypes
492 foreign function argtypes sequence as long as they provide a from_param
493 method, no longer is it required that the object is a ctypes type.
494
495- The '_ctypes' extension module now works when Python is configured
496 with the --without-threads option.
497
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000498- Bug #1513646: os.access on Windows now correctly determines write
499 access, again.
500
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000501- Bug #1512695: cPickle.loads could crash if it was interrupted with
502 a KeyboardInterrupt.
503
Neal Norwitza12aa882006-07-06 06:45:08 +0000504- Bug #1296433: parsing XML with a non-default encoding and
505 a CharacterDataHandler could crash the interpreter in pyexpat.
506
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000507- Patch #1516912: improve Modules support for OpenVMS.

510-----
511
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000512- Automate Windows build process for the Win64 SSL module.
513
Tim Peters32a83612006-07-10 21:08:24 +0000514- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000515 Previously, the slight difference could cause compilation errors of the
516 'zlib' module on systems with more than one version of zlib.
517
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000518- The MSI compileall step was fixed to also support a TARGETDIR
519 with spaces in it.
520

522 of Tcl/Tk.
523
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000524- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000525 trying to be installed even though it's empty.

549Core and builtins
550-----------------
551
Georg Brandla56b9152006-06-19 06:35:54 +0000552- Patch #1507676: Error messages returned by invalid abstract object operations
553 (such as iterating over an integer) have been improved and now include the
554 type of the offending object to help with debugging.
555
Brett Cannonea3912b2006-06-13 21:46:41 +0000556- Bug #992017: A classic class that defined a __coerce__() method that returned
557 its arguments swapped would infinitely recurse and segfault the interpreter.
558
Neal Norwitz909eb122006-06-12 02:13:21 +0000559- Fix the socket tests so they can be run concurrently.
560
Neal Norwitzb9845e72006-06-12 02:11:18 +0000561- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000562 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000563
Brett Cannon22565aa2006-06-09 22:31:23 +0000564- Bug #532646: object.__call__() will continue looking for the __call__
565 attribute on objects until one without one is found. This leads to recursion
566 when you take a class and set its __call__ attribute to an instance of the
567 class. Originally fixed for classic classes, but this fix is for new-style.
568 Removes the infinite_rec_3 crasher.
569
Georg Brandl24250812006-06-09 18:45:48 +0000570- The string and unicode methods startswith() and endswith() now accept
571 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
572
Brett Cannonde3b0522006-06-08 17:00:45 +0000573- Buffer objects, at the C level, never used the char buffer
574 implementation even when the char buffer for the wrapped object was
575 explicitly requested (originally returned the read or write buffer).
576 Now a TypeError is raised if the char buffer is not present but is
577 requested.
578
Georg Brandlddbaa662006-06-04 21:56:52 +0000579- Patch #1346214: Statements like "if 0: suite" are now again optimized
580 away like they were in Python 2.4.
581
Georg Brandlb7c8f542006-05-27 12:30:25 +0000582- Builtin exceptions are now full-blown new-style classes instead of
583 instances pretending to be classes, which speeds up exception handling
584 by about 80% in comparison to 2.5a2.
585
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000586- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
587 Unicode 4.1.
588
Georg Brandlf4ef1162006-05-26 18:03:31 +0000589- Patch #921466: sys.path_importer_cache is now used to cache valid and
590 invalid file paths for the built-in import machinery which leads to
591 fewer open calls on startup.
592
Tim Peters696cf432006-05-24 21:10:40 +0000593- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
594 of-2 bases. The largest speedup is for inputs with about 1000 decimal
595 digits. Conversion from non-power-of-2 bases remains quadratic-time in
596 the number of input digits (it was and remains linear-time for bases
597 2, 4, 8, 16 and 32).
598
Tim Petersb713ec22006-05-23 18:45:30 +0000599- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
600 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
601 an integer close to ``sys.maxint``. This was repaired by patch
602 #1335972, which also gives a nice speedup.
603
Richard Jonescebbefc2006-05-23 18:28:17 +0000604- Patch #1337051: reduced size of frame objects.
605
606- PyErr_NewException now accepts a tuple of base classes as its
607 "base" parameter.
608
Richard Jones7c88dcc2006-05-23 10:37:38 +0000609- Patch #876206: function call speedup by retaining allocated frame
610 objects.
611
Georg Brandl7b90e162006-05-18 07:01:27 +0000612- Bug #1462152: file() now checks more thoroughly for invalid mode
613 strings and removes a possible "U" before passing the mode to the
614 C library function.
615
Neal Norwitz1004a532006-05-15 07:17:23 +0000616- Patch #1488312, Fix memory alignment problem on SPARC in unicode
617
Neal Norwitz373f0a72006-05-15 07:04:36 +0000618- Bug #1487966: Fix SystemError with conditional expression in assignment
619
Martin v. Löwis879768d2006-05-11 13:28:43 +0000620- WindowsError now has two error code attributes: errno, which carries
621 the error values from errno.h, and winerror, which carries the error
622 values from winerror.h. Previous versions put the winerror.h values
623 (from GetLastError()) into the errno attribute.
624
Martin v. Löwis77736712006-05-04 05:51:03 +0000625- Patch #1475845: Raise IndentationError for unexpected indent.
626
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000627- Patch #1479181: split open() and file() from being aliases for each other.
628
Tim Peters44bd9862006-06-01 13:49:23 +0000629- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
630 methods were always silently ignored by dictionaries when comparing keys.
631 They are now passed through (except when using the C API function
632 ``PyDict_GetItem()``, whose semantics did not change).
633
634- Bug #1456209: In some obscure cases it was possible for a class with a
635 custom ``__eq__()`` method to confuse dict internals when class instances
636 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
637 No, you don't have any code that did this ;-)

643
644- Patch #1462338: Upgrade pyexpat to expat 2.0.0
645
Brett Cannon6ee7d012006-06-08 16:23:04 +0000646- Change binascii.hexlify to accept a read-only buffer instead of only a char
647 buffer and actually follow its documentation.
648
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000649- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
650
Nick Coghlanc649ec52006-05-29 12:43:05 +0000651- Patch #1478788 (modified version): The functional extension module has
652 been renamed to _functools and a functools Python wrapper module added.
653 This provides a home for additional function related utilities that are
654 not specifically about functional programming. See PEP 309.
655
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000656- Patch #1493701: performance enhancements for struct module.
657
Georg Brandl378d5922006-05-17 14:26:50 +0000658- Patch #1490224: time.altzone is now set correctly on Cygwin.
659
Georg Brandl8d3342b2006-05-16 07:38:27 +0000660- Patch #1435422: zlib's compress and decompress objects now have a
661 copy() method.
662
Andrew MacIntyre92913322006-06-13 15:04:24 +0000663- Patch #1454481: thread stack size is now tunable at runtime for thread
664 enabled builds on Windows and systems with Posix threads support.
665
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000666- On Win32, os.listdir now supports arbitrarily-long Unicode path names
667 (up to the system limit of 32K characters).
668
669- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
670 As a result, these functions now raise WindowsError instead of OSError.
671
Tim Peters7a822da2006-05-25 21:50:17 +0000672- ``time.clock()`` on Win64 should use the high-performance Windows
673 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
674 Windows platforms).
675
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000676- Calling Tk_Init twice is refused if the first call failed as that
677 may deadlock.
678
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000679- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
680 accept it without potentially using an uninitialized pointer.
681
682- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
683 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
684 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000685
Gregory P. Smith372b5832006-06-05 18:48:21 +0000686- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000687 [pybsddb project SF patch number 1466734]
688
Gregory P. Smith372b5832006-06-05 18:48:21 +0000689- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
690 parameter is supplied. [SF pybsddb bug #1477863]
691
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000692- bsddb: the __len__ method of a DB object has been fixed to return correct
693 results. It could previously incorrectly return 0 in some cases.
694 Fixes SF bug 1493322 (pybsddb bug 1184012).
695
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000696- bsddb: the bsddb.dbtables Modify method now raises the proper error and
697 aborts the db transaction safely when a modifier callback fails.
698 Fixes SF python patch/bug #1408584.
699
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000700- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000701 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000702 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
703 database calls that would previously deadlock. [SF python bug #775414]
704
Vinay Sajip28e57612006-07-01 10:45:20 +0000705- Patch #1446489: add support for the ZIP64 extensions to zipfile.

714 functions.
715
Martin v. Löwis3798da02006-06-17 18:44:27 +0000716- Patch #812986: Update turtle output even if not tracing.

720
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000721- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
722
Martin v. Löwis337487e2006-06-17 09:15:14 +0000723- Patch #763580: Add name and value arguments to Tkinter variable
724 classes.
725
Georg Brandl83cc0d02006-06-14 08:50:03 +0000726- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
727 mime.types file for determining MIME types.
728
Georg Brandl2605ca82006-06-14 06:08:31 +0000729- Bug #1339007: Shelf objects now don't raise an exception in their
730 __del__ method when initialization failed.
731
Martin v. Löwisd8251432006-06-14 05:21:04 +0000732- Patch #1455898: The MBCS codec now supports the incremental mode for
733 double-byte encodings.
734
Tim Peters43898b42006-06-14 04:09:25 +0000735- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
736 guarantee that adjacent triples in the return list always describe
737 non-adjacent blocks. Previously, a pair of matching blocks could end
738 up being described by multiple adjacent triples that formed a partition
739 of the matching pair.
740
Greg Ward0e0c9f42006-06-11 16:24:11 +0000741- Bug #1498146: fix optparse to handle Unicode strings in option help,
742 description, and epilog.
743
Greg Wardd1c797e2006-06-11 14:42:41 +0000744- Bug #1366250: minor optparse documentation error.
745
Greg Ward7f547402006-06-11 00:40:49 +0000746- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
747 clarify docs.
748
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000749- The wsgiref package has been added to the standard library.
750
Nick Coghlan676725d2006-06-08 13:54:49 +0000751- The functions update_wrapper() and wraps() have been added to the functools
752 module. These make it easier to copy relevant metadata from the original
753 function when writing wrapper functions.
754
Tim Petersd6a9eef2006-06-05 01:48:21 +0000755- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
756 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000757
Martin v. Löwis3f767792006-06-04 19:36:28 +0000758- Patch #1359618: Speed up charmap encoder by using a trie structure
759 for lookup.
760
Tim Petersd609b1a2006-06-02 23:22:51 +0000761- The functions in the ``pprint`` module now sort dictionaries by key
762 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
763 if and only if its display required more than one line, although that
764 wasn't documented. The new behavior increases predictability; e.g.,
765 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
766
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000767- Patch #1497027: try HTTP digest auth before basic auth in urllib2
768 (thanks for J. J. Lee).
769
Georg Brandl2b330372006-05-28 20:23:12 +0000770- Patch #1496206: improve urllib2 handling of passwords with respect to
771 default HTTP and HTTPS ports.
772
George Yoshidaf3c65de2006-05-28 16:39:09 +0000773- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
774
Bob Ippolito7298f272006-05-23 18:43:47 +0000775- Patch #1281707: speed up gzip.readline.
776
Georg Brandlb89316f2006-05-17 15:51:16 +0000777- Patch #1180296: Two new functions were added to the locale module:
778 format_string() to get the effect of "format % items" but locale-aware,
779 and currency() to format a monetary number with currency sign.
780
Georg Brandle3a25832006-05-17 14:56:04 +0000781- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
782 and several features added, such as speed and geometry control.
783
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000784- Patch #1488881: add support for external file objects in bz2 compressed
785 tarfiles.
786
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000787- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
788 stdout arguments, making it possible to redirect input and output
789 for remote debugging.
790
791- Patch #1484695: Update the tarfile module to version 0.8. This fixes
792 a couple of issues, notably handling of long file names using the
793 GNU LONGNAME extension.
794
795- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
796 new flag when ``name`` is already the name of an option flag.
797
798- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
799 package.
800
801- Patch #1472854: make the rlcompleter.Completer class usable on non-
802 UNIX platforms.
803
804- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
805
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000806- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000837What's New in Python 2.5 alpha 2?
838=================================
839
840*Release date: 27-APR-2006*
841
842Core and builtins
843-----------------
844
Thomas Heller1b046642006-04-18 18:51:06 +0000845- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
846 by converting these apis from macros into exported functions again:
847
848 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
849 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
850 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
851 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
852 PyRun_String Py_CompileString
853
Martin v. Löwis45294a92006-04-18 06:24:08 +0000854- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
855
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000856- All uses of PyStructSequence_InitType have been changed to initialize
857 the type objects only once, even if the interpreter is initialized
858 multiple times.
859
Neal Norwitz61546162006-04-14 05:20:28 +0000860- Bug #1454485, array.array('u') could crash the interpreter. This was
861 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
862 to unicode when it didn't make sense. 'u#' now requires a unicode string.
863
864- Py_UNICODE is unsigned. It was always documented as unsigned, but
865 due to a bug had a signed value in previous versions.
866
Tim Peters3a5e8b12006-04-11 01:44:07 +0000867- Patch #837242: ``id()`` of any Python object always gives a positive
868 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
869 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000870 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000871 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000872
Tim Peters3a5e8b12006-04-11 01:44:07 +0000873 def __hash__(self):
874 return id(self) # WRONG
875
876 because a hash result must be a (short) Python int but it was always
877 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000878 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000879 was always usable as a hash value before this patch. That's no longer
880 necessarily so.
881
882- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000883 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000884 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000885 #1454844)
886
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000887- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
888 involving generators that have paused outside of any ``try`` or ``with``
889 blocks. (In 2.5a1, a paused generator that was part of a reference
890 cycle could not be garbage collected, regardless of whether it was
891 paused in a ``try`` or ``with`` block.)

904- Bug #1117761: bsddb.*open() no longer raises an exception when using
905 the cachesize parameter.
906
907- Bug #1149413: bsddb.*open() no longer raises an exception when using
908 a temporary db (file=None) with the 'n' flag to truncate on open.
909
910- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
911 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000912
Armin Rigoa9017c32006-04-19 11:50:27 +0000913- Patch #1062014: AF_UNIX sockets under Linux have a special

917-------
918
Peter Astrand7d1d4362006-07-14 14:04:45 +0000919- Bug #1223937: subprocess.CalledProcessError reports the exit status
920 of the process using the returncode attribute, instead of
921 abusing errno.
922
Tim Peters711bf302006-04-25 03:31:36 +0000923- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
924 a doctest to be skipped (the code is not run, and the expected output
925 or exception is ignored).
926
Nick Coghlanda2268f2006-04-24 04:37:15 +0000927- Fixed contextlib.nested to cope with exceptions being raised and
928 caught inside exit handlers.
929
Greg Wardab05edc2006-04-23 03:47:58 +0000930- Updated optparse module to Optik 1.5.1 (allow numeric constants in
931 hex, octal, or binary; add ``append_const`` action; keep going if
932 gettext cannot be imported; added ``OptionParser.destroy()`` method;
933 added ``epilog`` for better help generation).
934
Tim Peters21fbd572006-04-21 21:18:10 +0000935- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
936 called from a thread spawned as a side effect of importing a module.
937
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000938- The pydoc module now supports documenting packages contained in
939 .zip or .egg files.
940
941- The pkgutil module now has several new utility functions, such
942 as ``walk_packages()`` to support working with packages that are either
943 in the filesystem or zip files.
944
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000945- The mailbox module can now modify and delete messages from
946 mailboxes, in addition to simply reading them. Thanks to Gregory
947 K. Johnson for writing the code, and to the 2005 Google Summer of
948 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000949
Tim Petersc7605f22006-04-17 21:12:33 +0000950- The ``__del__`` method of class ``local`` in module ``_threading_local``
951 returned before accomplishing any of its intended cleanup.

Anthony Baxtere29002c2006-04-12 12:07:31 +0000959- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
960 Windows. Bug #1469163.
961
Phillip J. Eby47032112006-04-11 01:07:43 +0000962- The warnings, linecache, inspect, traceback, site, and doctest modules
963 were updated to work correctly with modules imported from zipfiles or
964 via other PEP 302 __loader__ objects.

972
Skip Montanaro262fb922006-04-21 02:31:07 +0000973- The pstats.Stats class accepts an optional stream keyword argument to
974 direct output to an alternate file-like object.
975
Anthony Baxter51bcb682006-04-05 14:51:42 +0000976Build
977-----
978
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000979- The Makefile now has a reindent target, which runs reindent.py on
980 the library.
981
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000982- Patch #1470875: Building Python with MS Free Compiler
983
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000984- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000985
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000986- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
987 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000988 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000989 CXX from --with-cxx-main, see description in README.
990
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000991- Patch #1429775: Link extension modules with the shared libpython.
992
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000993- Fixed a libffi build problem on MIPS systems.
994
Tim Peters8931ff12006-05-13 23:28:20 +0000995- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
996 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
997 and "%zu" for unsigned integers of type ``size_t``.
998
Anthony Baxter51bcb682006-04-05 14:51:42 +0000999Tests
1000-----
1001
Nick Coghlanda2268f2006-04-24 04:37:15 +00001002- test_contextlib now checks contextlib.nested can cope with exceptions
1003 being raised and caught inside exit handlers.
1004
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001005- test_cmd_line now checks operation of the -m and -c command switches
1006
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001007- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1008 it separately and by hand. It also wasn't cleaning up its changes to
1009 the current Decimal context.
1010
Thomas Woutersabd08882006-04-26 15:53:30 +00001011- regrtest.py now has a -M option to run tests that test the new limits of
1012 containers, on 64-bit architectures. Running these tests is only sensible
1013 on 64-bit machines with more than two gigabytes of memory. The argument
1014 passed is the maximum amount of memory for the tests to use.
1015
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001016Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00001022Documentation
1023-------------
1024
Tim Petersb06d28c2006-05-12 01:57:59 +00001025- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1026
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001027- PEP 343: Added Context Types section to the library reference
1028 and attempted to bring other PEP 343 related documentation into
1029 line with the implementation and/or python-dev discussions.
1030
Tim Peters8dc73d22006-04-24 02:03:16 +00001031- Bug #1337990: clarified that ``doctest`` does not support examples
1032 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001035What's New in Python 2.5 alpha 1?
1036=================================
1037
Anthony Baxterebed3f62006-04-03 15:03:44 +00001038*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001039
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001040Core and builtins
1041-----------------
1042
Nick Coghlan43832302006-04-23 17:04:07 +00001043- PEP 338: -m command line switch now delegates to runpy.run_module
1044 allowing it to support modules in packages and zipfiles
1045
Martin v. Löwisc661b882006-04-20 04:54:23 +00001046- On Windows, .DLL is not an accepted file name extension for
1047 extension modules anymore; extensions are only found if they
1048 end in .PYD.
1049
Martin v. Löwisea62d252006-04-03 10:56:49 +00001050- Bug #1421664: sys.stderr.encoding is now set to the same value as
1051 sys.stdout.encoding.
1052
Neal Norwitz92e212f2006-04-03 04:48:37 +00001053- __import__ accepts keyword arguments.
1054
Georg Brandlccadf842006-03-31 18:54:53 +00001055- Patch #1460496: round() now accepts keyword arguments.
1056
Anthony Baxter262c00a2006-03-30 10:53:17 +00001057- Fixed bug #1459029 - unicode reprs were double-escaped.
1058
Hye-Shik Changd478f342006-03-23 12:32:36 +00001059- Patch #1396919: The system scope threads are reenabled on FreeBSD
1060 5.4 and later versions.
1061
Neal Norwitze98ccf62006-03-23 05:39:47 +00001062- Bug #1115379: Compiling a Unicode string with an encoding declaration
1063 now gives a SyntaxError.
1064
Georg Brandlabd1ff82006-03-18 07:59:59 +00001065- Previously, Python code had no easy way to access the contents of a
1066 cell object. Now, a ``cell_contents`` attribute has been added
1067 (closes patch #1170323).
1068
Tim Peterscf79aac2006-03-16 01:14:46 +00001069- Patch #1123430: Python's small-object allocator now returns an arena to
1070 the system ``free()`` when all memory within an arena becomes unused
1071 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1072 freed. Some applications will see a drop in virtual memory size now,
1073 especially long-running applications that, from time to time, temporarily
1074 use a large number of small objects. Note that when Python returns an
1075 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001076 platform C library will in turn return that memory to the operating system.
1077 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001078 appears to be effective at least on Microsoft C and gcc-based systems.
1079 Thanks to Evan Jones for hard work and patience.
1080
Georg Brandl533ff6f2006-03-08 18:09:27 +00001081- Patch #1434038: property() now uses the getter's docstring if there is
1082 no "doc" argument given. This makes it possible to legitimately use
1083 property() as a decorator to produce a read-only property.
1084
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001085- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1086 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1087 of requiring an int or long in slicing and a few other contexts, enabling
1088 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1089
Neal Norwitz995acdf2006-03-07 05:01:00 +00001090- Fixed various bugs reported by Coverity's Prevent tool.
1091
Brett Cannonbf364092006-03-01 04:25:17 +00001092- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1093 new exception base class, BaseException, which has a new message attribute.
1094 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1095 Raising a string exception now raises a DeprecationWarning.
1096
Thomas Woutersfb609f42006-02-28 16:37:25 +00001097- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1098 explicitly relative, using 'from .module import name' to mean 'from the same
1099 package as this module is in. Imports without dots still default to the
1100 old relative-then-absolute, unless 'from __future__ import
1101 absolute_import' is used.
1102
Brett Cannona7446e32006-02-27 23:39:10 +00001103- Properly check if 'warnings' raises an exception (usually when a filter set
1104 to "error" is triggered) when raising a warning for raising string
1105 exceptions.
1106
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001107- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001108 The name was removed from Include/code.h.
1109
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001110- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001111
Guido van Rossum1968ad32006-02-25 22:38:04 +00001112- Patch 1433928:
1113 - The copy module now "copies" function objects (as atomic objects).
1114 - dict.__getitem__ now looks for a __missing__ hook before raising
1115 KeyError.
1116
Tim Peters84ef21c2006-02-28 20:39:06 +00001117- PEP 343: with statement implemented. Needs ``from __future__ import
1118 with_statement``. Use of 'with' as a variable will generate a warning.
1119 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001120 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001121 The following objects have __context__ methods:
1122 - The built-in file type.
1123 - The thread.LockType type.
1124 - The following types defined by the threading module:
1125 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1126 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001127
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001128- Fix the encodings package codec search function to only search
1129 inside its own package. Fixes problem reported in patch #1433198.
1130
1131 Note: Codec packages should implement and register their own
1132 codec search function. PEP 100 has the details.
1133
Tim Peters9ea89d22006-06-04 03:26:02 +00001134- PEP 353: Using ``Py_ssize_t`` as the index type.
1135
1136- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1137 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1138 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1139 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1140 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001141
Neal Norwitzfc76d632006-01-10 06:03:13 +00001142- Patch #1400181, fix unicode string formatting to not use the locale.
1143 This is how string objects work. u'%f' could use , instead of .
1144 for the decimal point. Now both strings and unicode always use periods.
1145
Neal Norwitz671b9e32006-01-09 07:07:12 +00001146- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1147 configure would break checking curses.h.
1148
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001149- Bug #959576: The pwd module is now builtin. This allows Python to be
1150 built on UNIX platforms without $HOME set.
1151
Neal Norwitzc10978f2005-12-19 06:07:16 +00001152- Bug #1072182, fix some potential problems if characters are signed.
1153
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001154- Bug #889500, fix line number on SyntaxWarning for global declarations.
1155
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001156- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1157
Neal Norwitze7214a12005-12-18 05:03:17 +00001158- Support for converting hex strings to floats no longer works.
1159 This was not portable. float('0x3') now raises a ValueError.
1160
Barry Warsaw2a38a862005-12-18 01:27:35 +00001161- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001162 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001163 is now displayed in interactive prompt banner.
1164
Georg Brandlfa166682005-12-17 21:45:17 +00001165- Implementation of PEP 341 - Unification of try/except and try/finally.
1166 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001167 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001168
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001169- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1170 now encodes backslash correctly.
1171
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001172- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1173
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001174- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001175 and long longs.
1176
Neal Norwitz67715f02005-11-09 06:59:35 +00001177- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001178 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001179 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001180
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001181- Replaced most Unicode charmap codecs with new ones using the
1182 new Unicode translate string feature in the builtin charmap
1183 codec; the codecs were created from the mapping tables available
1184 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1185 encodings now include a mapping for the Apple logo)
1186
Tim Peterse3547fd2005-12-16 23:13:57 +00001187- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001188
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001189- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001190
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001191- A new AST parser implementation was completed. The abstract
1192 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001193 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001194
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001195- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001196 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1197
Neal Norwitz708e51a2005-10-03 04:48:15 +00001198- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1199
Neal Norwitz11bd1192005-10-03 00:54:56 +00001200- SF Bug #887946: fix segfault when redirecting stdin from a directory.

1205- SF bug #772896: unknown encoding results in MemoryError.
1206
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001207- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001208 supported a __len__() method which evaluated to False when the iterator
1209 was empty.
1210
Guido van Rossum630db602005-09-20 18:49:54 +00001211- On 64-bit platforms, when __len__() returns a value that cannot be
1212 represented as a C int, raise OverflowError.
1213
Skip Montanarof8948ca2005-09-19 03:54:46 +00001214- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001215 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001216
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001217- SF bug #893549: parsing keyword arguments was broken with a few format
1218 codes.
1219
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001220- Changes donated by Elemental Security to make it work on AIX 5.3
1221 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1222 bug #105470: test_pwd fails on 64bit system (Opteron).
1223
Guido van Rossum539c6622005-09-14 17:49:54 +00001224- Changes donated by Elemental Security to make it work on HP-UX 11 on
1225 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1226
Georg Brandl4550b8d2005-08-26 06:43:52 +00001227- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001228 (fixes bug #1119418).
1229
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001230- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1231
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001232- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1233 exceptions that cause a function to exit.
1234
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001235- The implementation of set() and frozenset() was revised to use its
1236 own internal data structure. Memory consumption is reduced by 1/3
1237 and there are modest speed-ups as well. The API is unchanged.
1238
Tim Petersde7990b2005-07-17 23:45:23 +00001239- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1240
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001241- SF bug #1229429: PyObject_CallMethod failed to decrement some
1242 reference counts in some error exit cases.
1243
Tim Petersecc6e6a2005-07-10 22:30:55 +00001244- SF bug #1185883: Python's small-object memory allocator took over
1245 a block managed by the platform C library whenever a realloc specified
1246 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001247 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001248 portable way to copy data from the C-managed block into Python's
1249 small-object space without risking a memory fault. Python's small-object
1250 realloc now leaves such blocks under the control of the platform C
1251 realloc.
1252
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001253- SF bug #1232517: An overflow error was not detected properly when
1254 attempting to convert a large float to an int in os.utime().
1255
Raymond Hettinger3296e692005-06-29 23:29:56 +00001256- SF bug #1224347: hex longs now print with lowercase letters just
1257 like their int counterparts.
1258
Michael W. Hudson188d4362005-06-20 16:52:57 +00001259- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1260 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1261 interpreter states; back out that fix and do a better job (see
1262 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1263 for a longer write-up of the problem).
1264
Michael W. Hudsondf888462005-06-03 14:41:55 +00001265- SF patch #1180995: marshal now uses a binary format by default when
1266 serializing floats.
1267
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001268- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1269 the routines that promise to produce IEEE 754 binary representations
1270 of floats now simply copy bytes around.
1271
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001272- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1273 278.
1274
Brett Cannonc3647ac2005-04-26 03:45:26 +00001275- patch #1109424: int, long, float, complex, and unicode now check for the
1276 proper magic slot for type conversions when subclassed. Previously the
1277 magic slot was ignored during conversion. Semantics now match the way
1278 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001279 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001280 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001281 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001282
Barry Warsawc8d907c2005-04-19 23:43:40 +00001283- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1284 NULL, now raise an AttributeError when attempting to set or delete the
1285 attribute. Previously a TypeError was raised, but this was inconsistent
1286 with the equivalent pure-Python implementation.
1287
Michael W. Hudson774479c2005-04-18 08:46:17 +00001288- It is now safe to call PyGILState_Release() before
1289 PyEval_InitThreads() (note that if there is reason to believe there
1290 are multiple threads around you still must call PyEval_InitThreads()
1291 before using the Python API; this fix is for extension modules that
1292 have no way of knowing if Python is multi-threaded yet).
1293
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001294- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1295 disabled caused a crash.
1296
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001297- Bug #1165306: instancemethod_new allowed the creation of a method
1298 with im_class == im_self == NULL, which caused a crash when called.
1299
Tim Petersecc6e6a2005-07-10 22:30:55 +00001300- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001301 fixes the crash seen in bug #1165761
1302
Raymond Hettinger96229b12005-03-11 06:49:40 +00001303- Added two new builtins, any() and all().
1304
Brett Cannon409d8f22005-03-05 06:47:57 +00001305- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001306 (e.g., ``class C(): pass`` is no longer a syntax error).
1307 Patch #1176012 added support to the 'parser' module and 'compiler' package
1308 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001309
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001310- Patch #1115086: Support PY_LONGLONG in structmember.
1311
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001312- Bug #1155938: new style classes did not check that __init__() was
1313 returning None.
1314
Tim Petersecc6e6a2005-07-10 22:30:55 +00001315- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001316 ('\') with a specific error message.
1317
Martin v. Löwisff232d72005-03-03 09:24:38 +00001318- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1319
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001320- Bug #1124295: the __name__ attribute of file objects was
1321 inadvertently made inaccessible in restricted mode.
1322
Tim Petersecc6e6a2005-07-10 22:30:55 +00001323- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001324 an ferror() call.
1325
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001326- min() and max() now support key= arguments with the same meaning as in
1327 list.sort().
1328
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001329- The peephole optimizer now performs simple constant folding in expressions:
1330 (2+3) --> (5).
1331
Raymond Hettingera422c342005-01-11 03:03:27 +00001332- set and frozenset objects can now be marshalled. SF #1098985.
1333
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001334- Bug #1077106: Poor argument checking could cause memory corruption
1335 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001336
Jeremy Hyltonab630502005-02-04 18:44:06 +00001337- The parser did not complain about future statements in illegal
1338 positions. It once again reports a syntax error if a future
1339 statement occurs after anything other than a doc string.
1340
Neil Schemenauercf52c072005-08-12 17:34:58 +00001341- Change the %s format specifier for str objects so that it returns a
1342 unicode instance if the argument is not an instance of basestring and
1343 calling __str__ on the argument returns a unicode instance.
1344
Tim Petersf4e69282006-02-27 17:15:31 +00001345- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1346 current thread state when the auto-GIL-state machinery knows about
1347 it (since the thread state is being deleted, continuing to remember it
1348 can't help, but can hurt if another thread happens to get created with
1349 the same thread id).
1350

1376
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001377- The unicodedata module was updated to the 4.1 version of the Unicode
1378 database. The 3.2 version is still available as unicodedata.db_3_2_0
1379 for applications that require this specific version (such as IDNA).
1380
Neal Norwitzb62c4332006-03-04 18:35:47 +00001381- The timing module is no longer built by default. It was deprecated
1382 in PEP 4 in Python 2.0 or earlier.
1383
Guido van Rossum1968ad32006-02-25 22:38:04 +00001384- Patch 1433928: Added a new type, defaultdict, to the collections module.
1385 This uses the new __missing__ hook behavior added to dict (see above).
1386
Georg Brandldbd83392006-02-20 09:42:33 +00001387- Bug #854823: socketmodule now builds on Sun platforms even when

1389
Georg Brandlf4f44152006-02-18 22:29:33 +00001390- Patch #1393157: os.startfile() now has an optional argument to specify
1391 a "command verb" to invoke on the file.
1392
Neal Norwitz082b2df2006-02-07 07:04:46 +00001393- Bug #876637, prevent stack corruption when socket descriptor

1402
Martin v. Löwis14694662006-02-03 12:54:16 +00001403- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1404 are reported, the limit on path name lengths is removed, and stat reports
1405 WindowsError now (instead of OSError).
1406
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001407- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

1482 the request code argument, which results in more C-like behaviour
1483 for large or negative values.
1484
Tim Petersecc6e6a2005-07-10 22:30:55 +00001485- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001541- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1542 been renamed to have only a single underscore prefix. This was done to
1543 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001544
Nick Coghlan43832302006-04-23 17:04:07 +00001545- PEP 338: new module runpy defines a run_module function to support
1546 executing modules which provide access to source code or a code object
1547 via the PEP 302 import mechanisms.
1548
Anthony Baxter93f5b932006-04-03 08:05:07 +00001549- The email module's parsedate_tz function now sets the daylight savings

1557 in attribute values.
1558
Anthony Baxterc51ee692006-04-01 00:57:31 +00001559- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001560 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001561 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001562 module will not be built.
1563
Tim Petersc17976e2006-04-01 00:26:53 +00001564- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1565 aren't officially supported here, and trying to use them will probably
1566 raise an exception some day. But dicts have been allowed, and "mostly
1567 worked", so support for them won't go away without warning.
1568
Georg Brandl338ef7d2006-03-31 18:42:16 +00001569- Bug #1445068: getpass.getpass() can now be given an explicit stream
1570 argument to specify where to write the prompt.
1571

1581 to make it easier to monitor when daemon threads have completed
1582 processing all enqueued tasks. Patch #1455676.
1583

1587
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001588- email 4.0 package now integrated. This is largely the same as the email 3.0
1589 package that was included in Python 2.3, except that PEP 8 module names are
1590 now used (e.g. mail.message instead of email.Message). The MIME classes
1591 have been moved to a subpackage (e.g. email.mime.text instead of
1592 email.MIMEText). The old names are still supported for now. Several
1593 deprecated Message methods have been removed and lots of bugs have been
1594 fixed. More details can be found in the email package documentation.
1595
Walter Dörwald40108c92006-03-27 08:15:44 +00001596- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1597 (a subclass of tuple) that provides incremental decoders and encoders
1598 (a way to use stateful codecs without the stream API). Python functions
1599 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1600 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1601 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001602
Walter Dörwald067db482006-03-15 22:17:27 +00001603- Patch #1359365: Calling next() on a closed StringIO.String object raises
1604 a ValueError instead of a StopIteration now (like file and cString.String do).
1605 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1606 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001607
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001608- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00001680 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1681 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1682 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1683 Ronald L. Rivest offered this advice for Python:
1684
1685 "The consensus of researchers in this area (at least as
1686 expressed at the NIST Hash Function Workshop 10/31/05),
1687 is that SHA-256 is a good choice for the time being, but
1688 that research should continue, and other alternatives may
1689 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001690
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001691- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00001737- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1738 ContentTooShortException, when the actually downloaded size does not
1739 match the Content-Length header.
1740
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00001741- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
1742
Martin v. Löwis56066d22005-08-24 07:38:12 +00001743- Bug #1178484: Return complete lines from codec stream readers
1744 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001745 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001746

1753
Guido van Rossum755149f2005-07-27 00:00:44 +00001754- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
1755 __hasattr__ and __delattr__ methods on class Tk that were breaking
1756 Tkdnd.
1757
Georg Brandl5dbda752005-07-17 20:27:41 +00001758- Bug #1015140: disambiguated the term "article id" in nntplib docs and
1759 docstrings to either "article number" or "message id".
1760
Georg Brandla4a8b822005-07-15 09:13:21 +00001761- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1762 parameter, but uses the usual "kwargs=None".
1763
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001764- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001765 Patch #1209527 (Contributed by Connelly).
1766
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001767- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1768 to W3C name (404 -> 'Not Found'). RFE #1216944.
1769
Georg Brandl9e43acf2005-07-04 17:16:07 +00001770- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1771 as this can cause problems with apps closing all file descriptors.
1772
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001773- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001774 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001775

1777
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001778- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1779 error messages.
1780
Georg Brandl379f99d2005-06-26 21:09:38 +00001781- Bug #1108948: Cookie.py produced invalid JavaScript code.
1782
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001783- The tokenize module now detects and reports indentation errors.
1784 Bug #1224621.
1785
Raymond Hettinger68c04532005-06-10 11:05:19 +00001786- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001787 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001788 the generate_tokens() function now accepts a callable argument that
1789 terminates by raising StopIteration.
1790
Georg Brandl9166e1a2005-06-04 09:20:03 +00001791- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1792
Georg Brandl268e61c2005-06-03 14:28:50 +00001793- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1794 component of the path.
1795
Skip Montanaro174dd222005-05-14 20:54:16 +00001796- Patch #1120353: The xmlrpclib module provides better, more transparent,
1797 support for datetime.{datetime,date,time} objects. With use_datetime set
1798 to True, applications shouldn't have to fiddle with the DateTime wrapper
1799 class at all.
1800
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001801- distutils.commands.upload was added to support uploading distribution
1802 files to PyPI.
1803
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001804- distutils.commands.register now encodes the data as UTF-8 before posting
1805 them to PyPI.
1806
Raymond Hettinger267b8682005-03-27 10:47:39 +00001807- decimal operator and comparison methods now return NotImplemented
1808 instead of raising a TypeError when interacting with other types. This
1809 allows other classes to implement __radd__ style methods and have them
1810 work as expected.
1811
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001812- Bug #1163325: Decimal infinities failed to hash. Attempting to
1813 hash a NaN raised an InvalidOperation instead of a TypeError.
1814
Tim Petersecc6e6a2005-07-10 22:30:55 +00001815- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001816 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1817

1847
Raymond Hettingerbab41432005-02-05 01:31:19 +00001848- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1849
Guido van Rossumd0641422005-02-03 15:01:24 +00001850- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1851 disables recursive traversal through instance attributes, which can
1852 be exploited in various ways.
1853
Tim Peterse3547fd2005-12-16 23:13:57 +00001854- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001855 flags on the HTTP listening socket.
1856
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001857- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1858 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1859
Fred Drakefbdeaad2006-07-29 16:56:15 +00001860- Patches #893642, #1039083: add allow_none, encoding arguments to
1861 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001862
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001863- Bug #1110478: Revert os.environ.update to do putenv again.
1864
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001865- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1866
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001867- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1868
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001869- Enhancements to the csv module:
1870
1871 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001872 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001873 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001874 + Dialect parameter parsing has been re-implemented to improve error
1875 reporting.
1876 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1877 dictates.
1878 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001879 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001880 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001881 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1882 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001883 + reader now allows \r characters to be quoted (previously it only allowed
1884 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001885 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001886 + Dialect classes passed to the module are no longer instantiated by
1887 the module before being parsed (the former validation scheme required
1888 this, but the mechanism was unreliable).
1889 + The dialect registry now contains instances of the internal
1890 C-coded dialect type, rather than references to python objects.
1891 + the internal c-coded dialect type is now immutable.
1892 + register_dialect now accepts the same keyword dialect specifications
1893 as the reader and writer, allowing the user to register dialects
1894 without first creating a dialect class.
1895 + a configurable limit to the size of parsed fields has been added -
1896 previously, an unmatched quote character could result in the entire
1897 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001898 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001899 the parser field size limit (returning the former limit). The initial
1900 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001901 + A line_num attribute has been added to the reader object, which tracks
1902 the number of lines read from the source iterator. This is not
1903 the same as the number of records returned, as records can span
1904 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001905 + reader and writer objects were not being registered with the cyclic-GC.
1906 This has been fixed.
1907
Brett Cannone6539c42005-01-08 02:43:53 +00001908- _DummyThread objects in the threading module now delete self.__block that is
1909 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1910 lock primitives tend to be limited in number and thus should not be wasted on
1911 a _DummyThread object. Fixes bug #1089632.
1912
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001913- The imghdr module now detects Exif files.
1914
Raymond Hettinger6065d322004-12-20 23:51:53 +00001915- StringIO.truncate() now correctly adjusts the size attribute.
1916 (Bug #951915).
1917
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001918- locale.py now uses an updated locale alias table (built using
1919 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1920 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001921 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001922
Raymond Hettinger3557f422004-12-07 12:02:02 +00001923- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1924
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001925- the pickle module no longer accepts the deprecated None option in the
1926 args tuple returned by __reduce__().
1927
Brett Cannon84667c02004-12-07 03:25:18 +00001928- optparse now optionally imports gettext. This allows its use in setup.py.
1929
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001930- the pickle module no longer uses the deprecated bin parameter.
1931
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001932- the shelve module no longer uses the deprecated binary parameter.
1933
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001934- the pstats module no longer uses the deprecated ignore() method.
1935
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001936- the filecmp module no longer uses the deprecated use_statcache argument.
1937
Raymond Hettinger664347b2004-12-04 21:21:53 +00001938- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1939 extended or overridden by subclasses. Formerly, the subclassed method would
1940 be ignored by the rest of the module. (Bug #1078905).
1941
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001942- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001943 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001944
Walter Dörwald36733692004-12-22 12:50:50 +00001945- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1946 once when a size argument is given. This prevents a buffer overflow in the
1947 tokenizer with very long source lines.
1948
Barry Warsaw538561e2006-01-01 21:48:54 +00001949- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1950 immediately after creating the object, without any intervening
1951 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001952
Skip Montanaro05885812005-01-16 20:48:27 +00001953- The reconvert.quote function can now emit triple-quoted strings. The
1954 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001955
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001956- ``UserString.MutableString`` now supports negative indices in
1957 ``__setitem__`` and ``__delitem__``
1958
Greg Ward40407942005-03-05 02:53:17 +00001959- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1960 correctly.
1961
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001962- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1963 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1964 character even if the user has passed a size parameter to get a proper
1965 line ending. Remove the special handling of a "\r\n" that has been split
1966 between two lines.
1967
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001968- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1969 about illegal code points. The codec now supports PEP 293 style error
1970 handlers.
1971
Walter Dörwald78a78b02005-09-01 12:04:29 +00001972- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001973 from the input stream, so that the output is a byte string in the correct
1974 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001975
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001976- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1977 considering it exactly like a '*'.
1978
Walter Dörwald007f8df2005-10-09 19:42:27 +00001979- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1980 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001981
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001982- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1983
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001984- Patch #1413711: Certain patterns of differences were making difflib
1985 touch the recursion limit.
1986
Walter Dörwald58917a62006-03-31 15:26:22 +00001987- Bug #947906: An object oriented interface has been added to the calendar
1988 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001989 called as a script (e.g. via ``python -mcalendar``). Localized month and
1990 weekday names can be ouput (even if an exotic encoding is used) using

1994-----
1995
Neal Norwitz602d3392006-03-31 08:21:40 +00001996- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1997 by using -mieee gcc option.
1998

2000
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002001- Build support for Win64-AMD64 was added.
2002
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002003- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2004
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002005- Patch #881820: look for openpty and forkpty also in libbsd.
2006
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002007- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2008 The zlib module is now builtin on Windows.
2009
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002010- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2011
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002012- Bug #1189330: configure did not correctly determine the necessary
2013 value of LINKCC if python was built with GCC 4.0.
2014
Trent Mick8321b422005-07-26 02:29:21 +00002015- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2016 vulnerability in zlib 1.2.1 and 1.2.2.
2017
Brett Cannon08cd5982005-04-24 22:26:38 +00002018- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2019 flags that change binary compatibility. Changes were also made to
2020 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002021 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002022
Bob Ippolitoed233462005-03-29 13:47:59 +00002023- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2024 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2025 no longer exists). This configure patch makes things right.
2026
Martin v. Löwise2713be2005-03-08 15:03:08 +00002027- Bug #1158607: Build with --disable-unicode again.
2028
Brett Cannon46d96232005-02-16 00:07:19 +00002029- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2030 defined. Discovered as a result of not being able to build on OS X.
2031
Brett Cannon516592f2004-12-07 00:42:59 +00002032- setup.py now uses the directories specified in LDFLAGS using the -L option
2033 and in CPPFLAGS using the -I option for adding library and include
2034 directories, respectively, for compiling extension modules against. This has
2035 led to the core being compiled using the values in CPPFLAGS. It also removes
2036 the need for the special-casing of both DarwinPorts and Fink for darwin since
2037 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2038 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2039 Fink, ``-I/opt/local/include`` for DarwinPorts).
2040
Brett Cannon43802422005-02-10 20:48:03 +00002041- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2042 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2043 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2044 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002046C API
2047-----
2048
Tim Petersc9d78aa2006-03-26 23:27:58 +00002049- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2050 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2051 is obtained via the ``PyObject_`` family, it must be released via the
2052 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2053 always been officially true, but when Python's small-object allocator was
2054 introduced, an attempt was made to cater to a few extension modules
2055 discovered at the time that obtained memory via ``PyObject_New`` but
2056 released it via ``PyMem_DEL``. It's years later, and if such code still
2057 exists it will fail now (probably with segfaults, but calling wrong
2058 low-level memory management functions can yield many symptoms).
2059
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002060- Added a C API for set and frozenset objects.
2061
Raymond Hettinger66517482004-12-03 11:45:13 +00002062- Removed PyRange_New().
2063
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002064- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2065 mapping argument now. This string is used as a mapping table. Byte values
2066 greater than the length of the string and 0xFFFE are treated as undefined
2067 mappings.

2072
Martin v. Löwis4d394df2005-01-23 09:19:22 +00002073- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002074
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002075- Patch #1276356: New resource "urlfetch" is implemented. This enables
2076 even impatient people to run tests that require remote files.
