Marc-André Lemburg040f76b2006-08-14 10:55:19 +000026- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000027 compared equal or unequal to a string and a UnicodeDecodeError
28 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +000029
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000030 Instead, the equal (==) and unequal (!=) comparison operators will
31 now issue a UnicodeWarning and interpret the two objects as
32 unequal. The UnicodeWarning can be filtered as desired using
33 the warning framework, e.g. silenced completely, turned into an
34 exception, logged, etc.
35
36 Note that compare operators other than equal and unequal will still
37 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +000038
Marc-André Lemburg757ea272006-08-14 11:44:34 +000039- Fix segfault when doing string formatting on subclasses of long.
40
41- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
42 with new-style classes.
43
44- Fix bug related to __len__ functions returning negative values with
45 classic classes.
46
47- Patch #1538606, Fix __index__() clipping. There were some problems
48 discovered with the API and how integers that didn't fit into Py_ssize_t
49 were handled. This patch attempts to provide enough alternatives
50 to effectively use __index__.
51
Martin v. Löwisab2f8f72006-08-09 07:57:39 +000052- Bug #1536021: __hash__ may now return long int; the final hash
53 value is obtained by invoking hash on the long int.
54
Thomas Hellerab1049c2006-08-08 17:37:00 +000055- Bug #1536786: buffer comparison could emit a RuntimeWarning.
56
Georg Brandl7e3ba2a2006-08-06 08:23:54 +000057- Bug #1535165: fixed a segfault in input() and raw_input() when
58 sys.stdin is closed.
59
Thomas Heller74d36f02006-08-04 18:17:40 +000060- On Windows, the PyErr_Warn function is now exported from
61 the Python dll again.
62
Neal Norwitz4ffedad2006-08-04 04:58:47 +000063- Bug #1191458: tracing over for loops now produces a line event
64 on each iteration. Fixing this problem required changing the .pyc
65 magic number. This means that .pyc files generated before 2.5c1
66 will be regenerated.
67
Neal Norwitz0cbd8052006-08-04 05:09:28 +000068- Bug #1333982: string/number constants were inappropriately stored
69 in the byte code and co_consts even if they were not used, ie
70 immediately popped off the stack.
71
Georg Brandle9462c72006-08-04 18:03:37 +000072- Fixed a reference-counting problem in property().

75Library
76-------
77
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +000078- Fix a bug in the ``compiler`` package that caused invalid code to be
79 generated for generator expressions.
80
Marc-André Lemburg574cfea2006-08-16 16:11:01 +000081- The distutils version has been changed to 2.5.0. The change to
82 keep it programmatically in sync with the Python version running
83 the code (introduced in 2.5b3) has been reverted. It will continue
84 to be maintained manually as static string literal.
85
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +000086- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +000087 and this cannot be converted to the required C type, an exception is
88 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +000089 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +000090
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000091- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +000092 an exception.
93
Anthony Baxter58179592006-08-16 13:08:25 +000094- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000095 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +000096 workarounds for clocks with low resolution, to stop the code yielding
97 duplicate UUIDs.
98
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +000099- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
100 before raising SystemExit, allowing IDLE to honor quit() and exit().
101
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000102- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
103
Georg Brandl7a1af772006-08-14 21:55:28 +0000104- Patch #1536071: trace.py should now find the full module name of a
105 file correctly even on Windows.
106
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000107- logging's atexit hook now runs even if the rest of the module has
108 already been cleaned up.
109
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000110- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000111
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000112- Bug #1531405, format_exception no longer raises an exception if
113 str(exception) raised an exception.
114
Neil Schemenauer06ded092006-08-04 16:20:30 +0000115- Fix a bug in the ``compiler`` package that caused invalid code to be
116 generated for nested functions.
117
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000118

Neal Norwitzbf8c1952006-08-15 04:14:57 +0000122- Patch #1511317: don't crash on invalid hostname (alias) info.
123
Georg Brandl3335a7a2006-08-14 21:42:55 +0000124- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
125 raises the correct exceptions.
126
Thomas Heller1ce433e2006-08-14 16:20:04 +0000127- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
128 '-no-stack-protector' compiler flag for OpenBSD has been removed.
129
Thomas Heller86720042006-08-14 11:17:48 +0000130- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
131 uses the _as_parameter_ attribute when objects are passed to foreign
132 function calls. The ctypes version number was changed to 1.0.1.
133
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000134- Bug #1530559, struct.pack raises TypeError where it used to convert.
135 Passing float arguments to struct.pack when integers are expected
136 now triggers a DeprecationWarning.
137
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000138
139Tests

160-----
161
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000162- Bug #1535502, build _hashlib on Windows, and use masm assembler
163 code in OpenSSL.
164
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000165- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000188*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000189
190Core and builtins
191-----------------
192
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000193- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000194 returned a long (see PEP 353).
195
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000196- Bug #1515471: string.replace() accepts character buffers again.
197
Neal Norwitz07aadb12006-07-30 06:55:48 +0000198- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
199 This provides the proper warning for struct.pack().
200 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
201
Neal Norwitz0d62a062006-07-30 06:53:31 +0000202- Patch #1531113: Fix augmented assignment with yield expressions.
203 Also fix a SystemError when trying to assign to yield expressions.
204
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000205- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
206 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
207 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
208 excessive filesystem operations during imports.
209
Tim Petersbc24eee2006-07-27 01:14:53 +0000210- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
211 operations on signed longs that are formally undefined by C.
212 Unfortunately, at least one compiler now cares about that, so complicated
213 the code to make that compiler happy again.
214
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000215- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
216
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000217- Patch #1232023: Stop including current directory in search
218 path on Windows.
219
Neal Norwitze1fdb322006-07-21 05:32:28 +0000220- Fix some potential crashes found with failmalloc.
221
Neal Norwitze7563102006-07-17 01:00:16 +0000222- Fix warnings reported by Klocwork's static analysis tool.
223
Neal Norwitz84be93b2006-07-16 01:50:38 +0000224- Bug #1512814, Fix incorrect lineno's when code within a function
225 had more than 255 blank lines.
226
Georg Brandl9dceedb2006-07-12 15:31:17 +0000227- Patch #1521179: Python now accepts the standard options ``--help`` and
228 ``--version`` as well as ``/?`` on Windows.
229
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000230- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000231 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000232 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000233
Tim Peters112aad32006-07-19 00:03:19 +0000234- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000235 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000236 new ``sys._current_frames()`` returns a dictionary with one entry,
237 mapping the faux "thread id" 0 to the current frame.
238
Ronald Oussoren3075e162006-07-25 20:28:55 +0000239- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000240
Ronald Oussoren3075e162006-07-25 20:28:55 +0000241
Neal Norwitza1f10902006-07-12 07:28:29 +0000242Library
243-------
244
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000245- Correction of patch #1455898: In the mbcs decoder, set final=False
246 for stream decoder, but final=True for the decode function.
247
Georg Brandl07fec3a2006-08-01 18:49:24 +0000248- os.urandom no longer masks unrelated exceptions like SystemExit or
249 KeyboardInterrupt.
250
Tim Peters4643c2f2006-08-10 22:45:34 +0000251- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000252 shutil.copytree on Windows
253
Georg Brandle34ac7c2006-07-30 11:07:23 +0000254- Bug #1002398: The documentation for os.path.sameopenfile now correctly
255 refers to file descriptors, not file objects.
256
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000257- The renaming of the xml package to xmlcore, and the import hackery done
258 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000259 #1513611, and probably others.
260
Georg Brandledd9b0d2006-07-29 09:33:26 +0000261- Bug #1441397: The compiler module now recognizes module and function
262 docstrings correctly as it did in Python 2.4.
263
Tim Peters6f681472006-07-27 23:44:37 +0000264- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
265 lost that tests are sorted by name before being run. This rarely
266 matters for well-written tests, but can create baffling symptoms if
267 side effects from one test to the next affect outcomes. ``DocTestFinder``
268 has been changed to sort the list of tests it returns.
269
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000270- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000271 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000272
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000273- Bug #978833: Really close underlying socket in _socketobject.close.
274
Georg Brandl0619a322006-07-26 07:40:17 +0000275- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
276 with title().
277
Georg Brandlcf0c1722006-07-26 07:23:32 +0000278- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
279 to recursive calls and call it with the failing package name.
280
Martin v. Löwis0b483032006-07-25 09:53:12 +0000281- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
282
Georg Brandlc13c34c2006-07-24 14:09:56 +0000283- Patch #1515343: Fix printing of deprecated string exceptions with a
284 value in the traceback module.
285
Greg Ward48fae7a2006-07-23 16:05:51 +0000286- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
287
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000288- Patch #1524429: Use repr() instead of backticks in Tkinter again.
289
Brett Cannoncaebe222006-07-18 04:41:36 +0000290- Bug #1520914: Change time.strftime() to accept a zero for any position in its
291 argument tuple. For arguments where zero is illegal, the value is forced to
292 the minimum value that is correct. This is to support an undocumented but
293 common way people used to fill in inconsequential information in the time
294 tuple pre-2.4.
295
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000296- Patch #1220874: Update the binhex module for Mach-O.
297
Barry Warsawb110bad2006-07-21 14:51:07 +0000298- The email package has improved RFC 2231 support, specifically for
299 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
300 (name*0=<blah>) parameter continuations. This may change the types of
301 values returned from email.message.Message.get_param() and friends.
302 Specifically in some cases where non-encoded continuations were used,
303 get_param() used to return a 3-tuple of (None, None, string) whereas now it
304 will just return the string (since non-encoded continuations don't have
305 charset and language parts).
306
307 Also, whereas % values were decoded in all parameter continuations, they are
308 now only decoded in encoded parameter parts.

Ronald Oussoren3075e162006-07-25 20:28:55 +0000310- Bug #1517990: IDLE keybindings on MacOS X now work correctly
311
312- Bug #1517996: IDLE now longer shows the default Tk menu when a
313 path browser, class browser or debugger is the frontmost window on MacOS X
314
Barry Warsaw00decd72006-07-27 23:43:15 +0000315- Patch #1520294: Support for getset and member descriptors in types.py,
316 inspect.py, and pydoc.py. Specifically, this allows for querying the type
317 of an object against these built-in types and more importantly, for getting
318 their docstrings printed in the interactive interpreter's help() function.

322-----------------
323
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000324- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
325 a socket operation on a socket with a timeout, the exception will be
326 caught correctly. Previously, the exception was not caught.
327
Thomas Heller1393d6a2006-07-28 21:43:20 +0000328- Patch #1529514: The _ctypes extension is now compiled on more
329 openbsd target platforms.
330
Tim Peters9cab5932006-07-28 00:30:00 +0000331- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
332 a memory leak, affecting pickles and deep copies.
333
Tim Petersbc24eee2006-07-27 01:14:53 +0000334- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

338
Thomas Hellerce049a02006-07-14 17:51:14 +0000339- Patch #1521817: Index range checking on ctypes arrays containing
340 exactly one element enabled again. This allows iterating over these
341 arrays, without the need to check the array size before.
342
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000343- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000344 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000345 /dev/null in certain cases; this is now fixed.
346
Thomas Heller47d7a062006-07-12 08:43:47 +0000347- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
348 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000349
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000350- Because of a misspelled preprocessor symbol, ctypes was always
351 compiled without thread support; this is now fixed.
352
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000353- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
354 methods now allow their database parameter to be None as the
355 sleepycat API allows.
356
Matt Flemingec926502006-07-28 11:27:27 +0000357- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
358 bluetooth API compared with Linux and FreeBSD.
359
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000360Tests
361-----
362
363- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
364 how long the test file should take to play. Now accepts taking 2.93 secs
365 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
366
Georg Brandl4793aa32006-07-28 18:31:39 +0000367- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
368 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
369 run via ``regrtest.py``. Now they do.

378
379- PythonLauncher now works correctly when the path to the script contains
380 characters that are treated specially by the shell (such as quotes).
381
382- Bug #1527397: PythonLauncher now launches scripts with the working directory
383 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000384 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000385 expect.

393Core and builtins
394-----------------
395
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000396- Bug #1441486: The literal representation of -(sys.maxint - 1)
397 again evaluates to a int object, not a long.
398
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000399- Bug #1501934: The scope of global variables that are locally assigned
400 using augmented assignment is now correctly determined.
401
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000402- Bug #927248: Recursive method-wrapper objects can now safely
403 be released.
404
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000405- Bug #1417699: Reject locale-specific decimal point in float()
406 and atof().
407
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000408- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
409 omit a default "error" argument for NULL pointer. This allows
410 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000411
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000412- Bug #1519018: 'as' is now validated properly in import statements.
413
Neal Norwitz28746ab2006-07-09 22:14:42 +0000414- On 64 bit systems, int literals that use less than 64 bits are
415 now ints rather than longs.
416
Neal Norwitzed657552006-07-10 00:04:44 +0000417- Bug #1512814, Fix incorrect lineno's when code at module scope
418 started after line 256.
419
Tim Peters32a83612006-07-10 21:08:24 +0000420- New function ``sys._current_frames()`` returns a dict mapping thread
421 id to topmost thread stack frame. This is for expert use, and is
422 especially useful for debugging application deadlocks. The functionality
423 was previously available in Fazal Majid's ``threadframe`` extension
424 module, but it wasn't possible to do this in a wholly threadsafe way from
425 an extension.

434
Tim Peters32a83612006-07-10 21:08:24 +0000435- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000436 environment variable to be set in order to the SDK environment

442
Thomas Woutersadd19112006-07-05 11:03:49 +0000443- string.Template() now correctly handles tuple-values. Previously,
444 multi-value tuples would raise an exception and single-value tuples would
445 be treated as the value they contain, instead.
446
Martin v. Löwisede77f52006-07-03 13:01:35 +0000447- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
448 even if some data are received.

454 degrees and radians.
455
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000456- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000457 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000458

460 is created.
461
Martin v. Löwis7596e832006-07-01 15:33:37 +0000462- Bug #1513223: .close() of a _socketobj now releases the underlying
463 socket again, which then gets closed as it becomes unreferenced.
464
Fred Drake10497c82006-06-29 02:57:48 +0000465- Bug #1504333: Make sgmllib support angle brackets in quoted
466 attribute values.
467
468- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
469 sgmllib ('[' and ']' were not accepted).
470
Georg Brandl1be63af2006-06-28 20:23:25 +0000471- Fix a bug in the turtle module's end_fill function.
472
Brett Cannon53ab5b72006-06-22 16:49:14 +0000473- Bug #1510580: The 'warnings' module improperly required that a Warning
474 category be either a types.ClassType and a subclass of Warning. The proper
475 check is just that it is a subclass with Warning as the documentation states.
476
Georg Brandlad29e632006-06-21 17:45:17 +0000477- The compiler module now correctly compiles the new try-except-finally
478 statement (bug #1509132).
479
Neal Norwitz60373cd2006-06-22 06:30:50 +0000480- The wsgiref package is now installed properly on Unix.
481
Vinay Sajip28e57612006-07-01 10:45:20 +0000482- A bug was fixed in logging.config.fileConfig() which caused a crash on
483 shutdown when fileConfig() was called multiple times.
484
Gerhard Häring762fbd32006-07-02 17:48:30 +0000485- The sqlite3 module did cut off data from the SQLite database at the first
486 null character before sending it to a custom converter. This has been fixed
487 now.

490-----------------
491
Tim Peters112aad32006-07-19 00:03:19 +0000492- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
493 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
494 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000495
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000496- Assigning None to pointer type fields in ctypes structures possible
497 overwrote the wrong fields, this is fixed now.
498
499- Fixed a segfault in _ctypes when ctypes.wintypes were imported
500 on non-Windows platforms.
501
502- Bug #1518190: The ctypes.c_void_p constructor now accepts any
503 integer or long, without range checking.
504
505- Patch #1517790: It is now possible to use custom objects in the ctypes
506 foreign function argtypes sequence as long as they provide a from_param
507 method, no longer is it required that the object is a ctypes type.
508
509- The '_ctypes' extension module now works when Python is configured
510 with the --without-threads option.
511
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000512- Bug #1513646: os.access on Windows now correctly determines write
513 access, again.
514
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000515- Bug #1512695: cPickle.loads could crash if it was interrupted with
516 a KeyboardInterrupt.
517
Neal Norwitza12aa882006-07-06 06:45:08 +0000518- Bug #1296433: parsing XML with a non-default encoding and
519 a CharacterDataHandler could crash the interpreter in pyexpat.
520
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000521- Patch #1516912: improve Modules support for OpenVMS.

525
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000526- Automate Windows build process for the Win64 SSL module.
527
Tim Peters32a83612006-07-10 21:08:24 +0000528- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000529 Previously, the slight difference could cause compilation errors of the
530 'zlib' module on systems with more than one version of zlib.
531
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000532- The MSI compileall step was fixed to also support a TARGETDIR
533 with spaces in it.

536 of Tcl/Tk.
537
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000538- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old

563Core and builtins
564-----------------
565
Georg Brandla56b9152006-06-19 06:35:54 +0000566- Patch #1507676: Error messages returned by invalid abstract object operations
567 (such as iterating over an integer) have been improved and now include the
568 type of the offending object to help with debugging.
569
Brett Cannonea3912b2006-06-13 21:46:41 +0000570- Bug #992017: A classic class that defined a __coerce__() method that returned
571 its arguments swapped would infinitely recurse and segfault the interpreter.
572
Neal Norwitz909eb122006-06-12 02:13:21 +0000573- Fix the socket tests so they can be run concurrently.
574
Neal Norwitzb9845e72006-06-12 02:11:18 +0000575- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000576 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000577
Brett Cannon22565aa2006-06-09 22:31:23 +0000578- Bug #532646: object.__call__() will continue looking for the __call__
579 attribute on objects until one without one is found. This leads to recursion
580 when you take a class and set its __call__ attribute to an instance of the
581 class. Originally fixed for classic classes, but this fix is for new-style.
582 Removes the infinite_rec_3 crasher.
583
Georg Brandl24250812006-06-09 18:45:48 +0000584- The string and unicode methods startswith() and endswith() now accept
585 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
586
Brett Cannonde3b0522006-06-08 17:00:45 +0000587- Buffer objects, at the C level, never used the char buffer
588 implementation even when the char buffer for the wrapped object was
589 explicitly requested (originally returned the read or write buffer).
590 Now a TypeError is raised if the char buffer is not present but is
591 requested.
592
Georg Brandlddbaa662006-06-04 21:56:52 +0000593- Patch #1346214: Statements like "if 0: suite" are now again optimized
594 away like they were in Python 2.4.
595
Georg Brandlb7c8f542006-05-27 12:30:25 +0000596- Builtin exceptions are now full-blown new-style classes instead of
597 instances pretending to be classes, which speeds up exception handling
598 by about 80% in comparison to 2.5a2.
599
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000600- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
601 Unicode 4.1.
602
Georg Brandlf4ef1162006-05-26 18:03:31 +0000603- Patch #921466: sys.path_importer_cache is now used to cache valid and
604 invalid file paths for the built-in import machinery which leads to
605 fewer open calls on startup.
606
Tim Peters696cf432006-05-24 21:10:40 +0000607- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
608 of-2 bases. The largest speedup is for inputs with about 1000 decimal
609 digits. Conversion from non-power-of-2 bases remains quadratic-time in
610 the number of input digits (it was and remains linear-time for bases
611 2, 4, 8, 16 and 32).
612
Tim Petersb713ec22006-05-23 18:45:30 +0000613- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
614 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
615 an integer close to ``sys.maxint``. This was repaired by patch
616 #1335972, which also gives a nice speedup.
617
Richard Jonescebbefc2006-05-23 18:28:17 +0000618- Patch #1337051: reduced size of frame objects.
619
620- PyErr_NewException now accepts a tuple of base classes as its
621 "base" parameter.
622
Richard Jones7c88dcc2006-05-23 10:37:38 +0000623- Patch #876206: function call speedup by retaining allocated frame
624 objects.
625
Georg Brandl7b90e162006-05-18 07:01:27 +0000626- Bug #1462152: file() now checks more thoroughly for invalid mode
627 strings and removes a possible "U" before passing the mode to the
628 C library function.
629
Neal Norwitz1004a532006-05-15 07:17:23 +0000630- Patch #1488312, Fix memory alignment problem on SPARC in unicode
631
Neal Norwitz373f0a72006-05-15 07:04:36 +0000632- Bug #1487966: Fix SystemError with conditional expression in assignment
633
Martin v. Löwis879768d2006-05-11 13:28:43 +0000634- WindowsError now has two error code attributes: errno, which carries
635 the error values from errno.h, and winerror, which carries the error
636 values from winerror.h. Previous versions put the winerror.h values
637 (from GetLastError()) into the errno attribute.
638
Martin v. Löwis77736712006-05-04 05:51:03 +0000639- Patch #1475845: Raise IndentationError for unexpected indent.
640
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000641- Patch #1479181: split open() and file() from being aliases for each other.
642
Tim Peters44bd9862006-06-01 13:49:23 +0000643- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
644 methods were always silently ignored by dictionaries when comparing keys.
645 They are now passed through (except when using the C API function
646 ``PyDict_GetItem()``, whose semantics did not change).
647
648- Bug #1456209: In some obscure cases it was possible for a class with a
649 custom ``__eq__()`` method to confuse dict internals when class instances
650 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
651 No, you don't have any code that did this ;-)

657
658- Patch #1462338: Upgrade pyexpat to expat 2.0.0
659
Brett Cannon6ee7d012006-06-08 16:23:04 +0000660- Change binascii.hexlify to accept a read-only buffer instead of only a char
661 buffer and actually follow its documentation.
662
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000663- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
664
Nick Coghlanc649ec52006-05-29 12:43:05 +0000665- Patch #1478788 (modified version): The functional extension module has
666 been renamed to _functools and a functools Python wrapper module added.
667 This provides a home for additional function related utilities that are
668 not specifically about functional programming. See PEP 309.
669
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000670- Patch #1493701: performance enhancements for struct module.
671
Georg Brandl378d5922006-05-17 14:26:50 +0000672- Patch #1490224: time.altzone is now set correctly on Cygwin.
673
Georg Brandl8d3342b2006-05-16 07:38:27 +0000674- Patch #1435422: zlib's compress and decompress objects now have a
675 copy() method.
676
Andrew MacIntyre92913322006-06-13 15:04:24 +0000677- Patch #1454481: thread stack size is now tunable at runtime for thread
678 enabled builds on Windows and systems with Posix threads support.
679
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000680- On Win32, os.listdir now supports arbitrarily-long Unicode path names
681 (up to the system limit of 32K characters).
682
683- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
684 As a result, these functions now raise WindowsError instead of OSError.
685
Tim Peters7a822da2006-05-25 21:50:17 +0000686- ``time.clock()`` on Win64 should use the high-performance Windows
687 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
688 Windows platforms).
689
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000690- Calling Tk_Init twice is refused if the first call failed as that
691 may deadlock.
692
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000693- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
694 accept it without potentially using an uninitialized pointer.
695
696- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
697 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
698 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000699
Gregory P. Smith372b5832006-06-05 18:48:21 +0000700- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000701 [pybsddb project SF patch number 1466734]
702
Gregory P. Smith372b5832006-06-05 18:48:21 +0000703- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
704 parameter is supplied. [SF pybsddb bug #1477863]
705
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000706- bsddb: the __len__ method of a DB object has been fixed to return correct
707 results. It could previously incorrectly return 0 in some cases.
708 Fixes SF bug 1493322 (pybsddb bug 1184012).
709
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000710- bsddb: the bsddb.dbtables Modify method now raises the proper error and
711 aborts the db transaction safely when a modifier callback fails.
712 Fixes SF python patch/bug #1408584.
713
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000714- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000715 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000716 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
717 database calls that would previously deadlock. [SF python bug #775414]
718
Vinay Sajip28e57612006-07-01 10:45:20 +0000719- Patch #1446489: add support for the ZIP64 extensions to zipfile.

738 classes.
739
Georg Brandl83cc0d02006-06-14 08:50:03 +0000740- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
741 mime.types file for determining MIME types.
742
Georg Brandl2605ca82006-06-14 06:08:31 +0000743- Bug #1339007: Shelf objects now don't raise an exception in their
744 __del__ method when initialization failed.
745
Martin v. Löwisd8251432006-06-14 05:21:04 +0000746- Patch #1455898: The MBCS codec now supports the incremental mode for
747 double-byte encodings.
748
Tim Peters43898b42006-06-14 04:09:25 +0000749- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
750 guarantee that adjacent triples in the return list always describe
751 non-adjacent blocks. Previously, a pair of matching blocks could end
752 up being described by multiple adjacent triples that formed a partition
753 of the matching pair.
754
Greg Ward0e0c9f42006-06-11 16:24:11 +0000755- Bug #1498146: fix optparse to handle Unicode strings in option help,
756 description, and epilog.
757
Greg Wardd1c797e2006-06-11 14:42:41 +0000758- Bug #1366250: minor optparse documentation error.
759
Greg Ward7f547402006-06-11 00:40:49 +0000760- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
761 clarify docs.
762
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000763- The wsgiref package has been added to the standard library.
764
Nick Coghlan676725d2006-06-08 13:54:49 +0000765- The functions update_wrapper() and wraps() have been added to the functools
766 module. These make it easier to copy relevant metadata from the original
767 function when writing wrapper functions.
768
Tim Petersd6a9eef2006-06-05 01:48:21 +0000769- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
770 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000771
Martin v. Löwis3f767792006-06-04 19:36:28 +0000772- Patch #1359618: Speed up charmap encoder by using a trie structure
773 for lookup.
774
Tim Petersd609b1a2006-06-02 23:22:51 +0000775- The functions in the ``pprint`` module now sort dictionaries by key
776 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
777 if and only if its display required more than one line, although that
778 wasn't documented. The new behavior increases predictability; e.g.,
779 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
780
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000781- Patch #1497027: try HTTP digest auth before basic auth in urllib2
782 (thanks for J. J. Lee).
783
Georg Brandl2b330372006-05-28 20:23:12 +0000784- Patch #1496206: improve urllib2 handling of passwords with respect to
785 default HTTP and HTTPS ports.
786
George Yoshidaf3c65de2006-05-28 16:39:09 +0000787- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
788
Bob Ippolito7298f272006-05-23 18:43:47 +0000789- Patch #1281707: speed up gzip.readline.
790
Georg Brandlb89316f2006-05-17 15:51:16 +0000791- Patch #1180296: Two new functions were added to the locale module:
792 format_string() to get the effect of "format % items" but locale-aware,
793 and currency() to format a monetary number with currency sign.
794
Georg Brandle3a25832006-05-17 14:56:04 +0000795- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
796 and several features added, such as speed and geometry control.
797
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000798- Patch #1488881: add support for external file objects in bz2 compressed
799 tarfiles.
800
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000801- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
802 stdout arguments, making it possible to redirect input and output
803 for remote debugging.
804
805- Patch #1484695: Update the tarfile module to version 0.8. This fixes
806 a couple of issues, notably handling of long file names using the
807 GNU LONGNAME extension.
808
809- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
810 new flag when ``name`` is already the name of an option flag.
811
812- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
813 package.
814
815- Patch #1472854: make the rlcompleter.Completer class usable on non-
816 UNIX platforms.
817
818- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000820- Bug #1472827: correctly escape newlines and tabs in attribute values in

853
854*Release date: 27-APR-2006*
855
856Core and builtins
857-----------------
858
Thomas Heller1b046642006-04-18 18:51:06 +0000859- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
860 by converting these apis from macros into exported functions again:
861
862 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
863 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
864 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
865 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
866 PyRun_String Py_CompileString
867
Martin v. Löwis45294a92006-04-18 06:24:08 +0000868- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
869
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000870- All uses of PyStructSequence_InitType have been changed to initialize
871 the type objects only once, even if the interpreter is initialized
872 multiple times.
873
Neal Norwitz61546162006-04-14 05:20:28 +0000874- Bug #1454485, array.array('u') could crash the interpreter. This was
875 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
876 to unicode when it didn't make sense. 'u#' now requires a unicode string.
877
878- Py_UNICODE is unsigned. It was always documented as unsigned, but
879 due to a bug had a signed value in previous versions.
880
Tim Peters3a5e8b12006-04-11 01:44:07 +0000881- Patch #837242: ``id()`` of any Python object always gives a positive
882 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
883 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000884 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000885 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000886
Tim Peters3a5e8b12006-04-11 01:44:07 +0000887 def __hash__(self):
888 return id(self) # WRONG
889
890 because a hash result must be a (short) Python int but it was always
891 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000892 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000893 was always usable as a hash value before this patch. That's no longer
894 necessarily so.
895
896- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000897 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000898 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000899 #1454844)
900
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000901- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
902 involving generators that have paused outside of any ``try`` or ``with``
903 blocks. (In 2.5a1, a paused generator that was part of a reference
904 cycle could not be garbage collected, regardless of whether it was
905 paused in a ``try`` or ``with`` block.)

918- Bug #1117761: bsddb.*open() no longer raises an exception when using
919 the cachesize parameter.
920
921- Bug #1149413: bsddb.*open() no longer raises an exception when using
922 a temporary db (file=None) with the 'n' flag to truncate on open.
923
924- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
925 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000926
Armin Rigoa9017c32006-04-19 11:50:27 +0000927- Patch #1062014: AF_UNIX sockets under Linux have a special
928 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +0000933- Bug #1223937: subprocess.CalledProcessError reports the exit status
934 of the process using the returncode attribute, instead of
935 abusing errno.
936
Tim Peters711bf302006-04-25 03:31:36 +0000937- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
938 a doctest to be skipped (the code is not run, and the expected output
939 or exception is ignored).
940
Nick Coghlanda2268f2006-04-24 04:37:15 +0000941- Fixed contextlib.nested to cope with exceptions being raised and
942 caught inside exit handlers.
943
Greg Wardab05edc2006-04-23 03:47:58 +0000944- Updated optparse module to Optik 1.5.1 (allow numeric constants in
945 hex, octal, or binary; add ``append_const`` action; keep going if
946 gettext cannot be imported; added ``OptionParser.destroy()`` method;
947 added ``epilog`` for better help generation).
948
Tim Peters21fbd572006-04-21 21:18:10 +0000949- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
950 called from a thread spawned as a side effect of importing a module.
951
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000952- The pydoc module now supports documenting packages contained in
953 .zip or .egg files.
954
955- The pkgutil module now has several new utility functions, such
956 as ``walk_packages()`` to support working with packages that are either
957 in the filesystem or zip files.
958
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000959- The mailbox module can now modify and delete messages from
960 mailboxes, in addition to simply reading them. Thanks to Gregory
961 K. Johnson for writing the code, and to the 2005 Google Summer of
962 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000963
Tim Petersc7605f22006-04-17 21:12:33 +0000964- The ``__del__`` method of class ``local`` in module ``_threading_local``
965 returned before accomplishing any of its intended cleanup.

972
Anthony Baxtere29002c2006-04-12 12:07:31 +0000973- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
974 Windows. Bug #1469163.
975
Phillip J. Eby47032112006-04-11 01:07:43 +0000976- The warnings, linecache, inspect, traceback, site, and doctest modules
977 were updated to work correctly with modules imported from zipfiles or
978 via other PEP 302 __loader__ objects.
979
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000980- Patch #1467770: Reduce usage of subprocess._active to processes which
981 the application hasn't waited on.
982
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000983- Patch #1462222: Fix Tix.Grid.

986
Skip Montanaro262fb922006-04-21 02:31:07 +0000987- The pstats.Stats class accepts an optional stream keyword argument to
988 direct output to an alternate file-like object.
989
Anthony Baxter51bcb682006-04-05 14:51:42 +0000990Build
991-----
992
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000993- The Makefile now has a reindent target, which runs reindent.py on
994 the library.
995
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000996- Patch #1470875: Building Python with MS Free Compiler
997
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000998- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000999
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001000- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1001 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001002 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001003 CXX from --with-cxx-main, see description in README.
1004
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001005- Patch #1429775: Link extension modules with the shared libpython.
1006
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001007- Fixed a libffi build problem on MIPS systems.
1008
Tim Peters8931ff12006-05-13 23:28:20 +00001009- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1010 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1011 and "%zu" for unsigned integers of type ``size_t``.
1012
Anthony Baxter51bcb682006-04-05 14:51:42 +00001013Tests
1014-----
1015
Nick Coghlanda2268f2006-04-24 04:37:15 +00001016- test_contextlib now checks contextlib.nested can cope with exceptions
1017 being raised and caught inside exit handlers.
1018
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001019- test_cmd_line now checks operation of the -m and -c command switches
1020
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001021- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1022 it separately and by hand. It also wasn't cleaning up its changes to
1023 the current Decimal context.
1024
Thomas Woutersabd08882006-04-26 15:53:30 +00001025- regrtest.py now has a -M option to run tests that test the new limits of
1026 containers, on 64-bit architectures. Running these tests is only sensible
1027 on 64-bit machines with more than two gigabytes of memory. The argument
1028 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001036Documentation
1037-------------
1038
Tim Petersb06d28c2006-05-12 01:57:59 +00001039- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1040
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001041- PEP 343: Added Context Types section to the library reference
1042 and attempted to bring other PEP 343 related documentation into
1043 line with the implementation and/or python-dev discussions.
1044
Tim Peters8dc73d22006-04-24 02:03:16 +00001045- Bug #1337990: clarified that ``doctest`` does not support examples
1046 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001047

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001049What's New in Python 2.5 alpha 1?
1050=================================
1051
Anthony Baxterebed3f62006-04-03 15:03:44 +00001052*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001053
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001054Core and builtins
1055-----------------
1056
Nick Coghlan43832302006-04-23 17:04:07 +00001057- PEP 338: -m command line switch now delegates to runpy.run_module
1058 allowing it to support modules in packages and zipfiles
1059
Martin v. Löwisc661b882006-04-20 04:54:23 +00001060- On Windows, .DLL is not an accepted file name extension for
1061 extension modules anymore; extensions are only found if they
1062 end in .PYD.
1063
Martin v. Löwisea62d252006-04-03 10:56:49 +00001064- Bug #1421664: sys.stderr.encoding is now set to the same value as
1065 sys.stdout.encoding.
1066
Neal Norwitz92e212f2006-04-03 04:48:37 +00001067- __import__ accepts keyword arguments.
1068
Georg Brandlccadf842006-03-31 18:54:53 +00001069- Patch #1460496: round() now accepts keyword arguments.
1070
Anthony Baxter262c00a2006-03-30 10:53:17 +00001071- Fixed bug #1459029 - unicode reprs were double-escaped.
1072
Hye-Shik Changd478f342006-03-23 12:32:36 +00001073- Patch #1396919: The system scope threads are reenabled on FreeBSD
1074 5.4 and later versions.
1075
Neal Norwitze98ccf62006-03-23 05:39:47 +00001076- Bug #1115379: Compiling a Unicode string with an encoding declaration
1077 now gives a SyntaxError.
1078
Georg Brandlabd1ff82006-03-18 07:59:59 +00001079- Previously, Python code had no easy way to access the contents of a
1080 cell object. Now, a ``cell_contents`` attribute has been added
1081 (closes patch #1170323).
1082
Tim Peterscf79aac2006-03-16 01:14:46 +00001083- Patch #1123430: Python's small-object allocator now returns an arena to
1084 the system ``free()`` when all memory within an arena becomes unused
1085 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1086 freed. Some applications will see a drop in virtual memory size now,
1087 especially long-running applications that, from time to time, temporarily
1088 use a large number of small objects. Note that when Python returns an
1089 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001090 platform C library will in turn return that memory to the operating system.
1091 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001092 appears to be effective at least on Microsoft C and gcc-based systems.
1093 Thanks to Evan Jones for hard work and patience.
1094
Georg Brandl533ff6f2006-03-08 18:09:27 +00001095- Patch #1434038: property() now uses the getter's docstring if there is
1096 no "doc" argument given. This makes it possible to legitimately use
1097 property() as a decorator to produce a read-only property.
1098
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001099- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1100 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1101 of requiring an int or long in slicing and a few other contexts, enabling
1102 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1103
Neal Norwitz995acdf2006-03-07 05:01:00 +00001104- Fixed various bugs reported by Coverity's Prevent tool.
1105
Brett Cannonbf364092006-03-01 04:25:17 +00001106- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1107 new exception base class, BaseException, which has a new message attribute.
1108 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1109 Raising a string exception now raises a DeprecationWarning.
1110
Thomas Woutersfb609f42006-02-28 16:37:25 +00001111- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1112 explicitly relative, using 'from .module import name' to mean 'from the same
1113 package as this module is in. Imports without dots still default to the
1114 old relative-then-absolute, unless 'from __future__ import
1115 absolute_import' is used.
1116
Brett Cannona7446e32006-02-27 23:39:10 +00001117- Properly check if 'warnings' raises an exception (usually when a filter set
1118 to "error" is triggered) when raising a warning for raising string
1119 exceptions.
1120
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001121- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001122 The name was removed from Include/code.h.
1123
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001124- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001125
Guido van Rossum1968ad32006-02-25 22:38:04 +00001126- Patch 1433928:
1127 - The copy module now "copies" function objects (as atomic objects).
1128 - dict.__getitem__ now looks for a __missing__ hook before raising
1129 KeyError.
1130
Tim Peters84ef21c2006-02-28 20:39:06 +00001131- PEP 343: with statement implemented. Needs ``from __future__ import
1132 with_statement``. Use of 'with' as a variable will generate a warning.
1133 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001134 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001135 The following objects have __context__ methods:
1136 - The built-in file type.
1137 - The thread.LockType type.
1138 - The following types defined by the threading module:
1139 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1140 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001141
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001142- Fix the encodings package codec search function to only search
1143 inside its own package. Fixes problem reported in patch #1433198.
1144
1145 Note: Codec packages should implement and register their own
1146 codec search function. PEP 100 has the details.
1147
Tim Peters9ea89d22006-06-04 03:26:02 +00001148- PEP 353: Using ``Py_ssize_t`` as the index type.
1149
1150- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1151 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1152 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1153 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1154 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001155
Neal Norwitzfc76d632006-01-10 06:03:13 +00001156- Patch #1400181, fix unicode string formatting to not use the locale.
1157 This is how string objects work. u'%f' could use , instead of .
1158 for the decimal point. Now both strings and unicode always use periods.
1159
Neal Norwitz671b9e32006-01-09 07:07:12 +00001160- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1161 configure would break checking curses.h.
1162
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001163- Bug #959576: The pwd module is now builtin. This allows Python to be
1164 built on UNIX platforms without $HOME set.
1165
Neal Norwitzc10978f2005-12-19 06:07:16 +00001166- Bug #1072182, fix some potential problems if characters are signed.
1167
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001168- Bug #889500, fix line number on SyntaxWarning for global declarations.
1169
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001170- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1171
Neal Norwitze7214a12005-12-18 05:03:17 +00001172- Support for converting hex strings to floats no longer works.
1173 This was not portable. float('0x3') now raises a ValueError.
1174
Barry Warsaw2a38a862005-12-18 01:27:35 +00001175- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001176 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001177 is now displayed in interactive prompt banner.
1178
Georg Brandlfa166682005-12-17 21:45:17 +00001179- Implementation of PEP 341 - Unification of try/except and try/finally.
1180 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001181 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001182
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001183- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1184 now encodes backslash correctly.
1185
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001186- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1187
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001188- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001189 and long longs.
1190
Neal Norwitz67715f02005-11-09 06:59:35 +00001191- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001192 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001193 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001194
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001195- Replaced most Unicode charmap codecs with new ones using the
1196 new Unicode translate string feature in the builtin charmap
1197 codec; the codecs were created from the mapping tables available
1198 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1199 encodings now include a mapping for the Apple logo)
1200
Tim Peterse3547fd2005-12-16 23:13:57 +00001201- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001202
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001203- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001204
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001205- A new AST parser implementation was completed. The abstract
1206 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001207 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001208
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001209- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001210 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1211
Neal Norwitz708e51a2005-10-03 04:48:15 +00001212- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1213
Neal Norwitz11bd1192005-10-03 00:54:56 +00001214- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1215 Provide a warning when a directory is passed on the command line.
1216
Neal Norwitz40d37812005-10-02 01:48:49 +00001217- Fix segfault with invalid coding.
1218
1219- SF bug #772896: unknown encoding results in MemoryError.
1220
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001221- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001222 supported a __len__() method which evaluated to False when the iterator
1223 was empty.
1224
Guido van Rossum630db602005-09-20 18:49:54 +00001225- On 64-bit platforms, when __len__() returns a value that cannot be
1226 represented as a C int, raise OverflowError.
1227
Skip Montanarof8948ca2005-09-19 03:54:46 +00001228- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001229 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001230
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001231- SF bug #893549: parsing keyword arguments was broken with a few format
1232 codes.
1233
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001234- Changes donated by Elemental Security to make it work on AIX 5.3
1235 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1236 bug #105470: test_pwd fails on 64bit system (Opteron).
1237
Guido van Rossum539c6622005-09-14 17:49:54 +00001238- Changes donated by Elemental Security to make it work on HP-UX 11 on
1239 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1240
Georg Brandl4550b8d2005-08-26 06:43:52 +00001241- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001242 (fixes bug #1119418).
1243
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001244- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1245
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001246- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1247 exceptions that cause a function to exit.
1248
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001249- The implementation of set() and frozenset() was revised to use its
1250 own internal data structure. Memory consumption is reduced by 1/3
1251 and there are modest speed-ups as well. The API is unchanged.
1252
Tim Petersde7990b2005-07-17 23:45:23 +00001253- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1254
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001255- SF bug #1229429: PyObject_CallMethod failed to decrement some
1256 reference counts in some error exit cases.
1257
Tim Petersecc6e6a2005-07-10 22:30:55 +00001258- SF bug #1185883: Python's small-object memory allocator took over
1259 a block managed by the platform C library whenever a realloc specified
1260 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001261 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001262 portable way to copy data from the C-managed block into Python's
1263 small-object space without risking a memory fault. Python's small-object
1264 realloc now leaves such blocks under the control of the platform C
1265 realloc.
1266
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001267- SF bug #1232517: An overflow error was not detected properly when
1268 attempting to convert a large float to an int in os.utime().
1269
Raymond Hettinger3296e692005-06-29 23:29:56 +00001270- SF bug #1224347: hex longs now print with lowercase letters just
1271 like their int counterparts.
1272
Michael W. Hudson188d4362005-06-20 16:52:57 +00001273- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1274 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1275 interpreter states; back out that fix and do a better job (see
1276 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1277 for a longer write-up of the problem).
1278
Michael W. Hudsondf888462005-06-03 14:41:55 +00001279- SF patch #1180995: marshal now uses a binary format by default when
1280 serializing floats.
1281
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001282- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1283 the routines that promise to produce IEEE 754 binary representations
1284 of floats now simply copy bytes around.
1285
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001286- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1287 278.
1288
Brett Cannonc3647ac2005-04-26 03:45:26 +00001289- patch #1109424: int, long, float, complex, and unicode now check for the
1290 proper magic slot for type conversions when subclassed. Previously the
1291 magic slot was ignored during conversion. Semantics now match the way
1292 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001293 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001294 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001295 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001296
Barry Warsawc8d907c2005-04-19 23:43:40 +00001297- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1298 NULL, now raise an AttributeError when attempting to set or delete the
1299 attribute. Previously a TypeError was raised, but this was inconsistent
1300 with the equivalent pure-Python implementation.
1301
Michael W. Hudson774479c2005-04-18 08:46:17 +00001302- It is now safe to call PyGILState_Release() before
1303 PyEval_InitThreads() (note that if there is reason to believe there
1304 are multiple threads around you still must call PyEval_InitThreads()
1305 before using the Python API; this fix is for extension modules that
1306 have no way of knowing if Python is multi-threaded yet).
1307
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001308- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1309 disabled caused a crash.
1310
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001311- Bug #1165306: instancemethod_new allowed the creation of a method
1312 with im_class == im_self == NULL, which caused a crash when called.
1313
Tim Petersecc6e6a2005-07-10 22:30:55 +00001314- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001315 fixes the crash seen in bug #1165761
1316
Raymond Hettinger96229b12005-03-11 06:49:40 +00001317- Added two new builtins, any() and all().
1318
Brett Cannon409d8f22005-03-05 06:47:57 +00001319- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001320 (e.g., ``class C(): pass`` is no longer a syntax error).
1321 Patch #1176012 added support to the 'parser' module and 'compiler' package
1322 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001323
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001324- Patch #1115086: Support PY_LONGLONG in structmember.
1325
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001326- Bug #1155938: new style classes did not check that __init__() was
1327 returning None.
1328
Tim Petersecc6e6a2005-07-10 22:30:55 +00001329- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001330 ('\') with a specific error message.
1331
Martin v. Löwisff232d72005-03-03 09:24:38 +00001332- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1333
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001334- Bug #1124295: the __name__ attribute of file objects was
1335 inadvertently made inaccessible in restricted mode.
1336
Tim Petersecc6e6a2005-07-10 22:30:55 +00001337- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001338 an ferror() call.
1339
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001340- min() and max() now support key= arguments with the same meaning as in
1341 list.sort().
1342
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001343- The peephole optimizer now performs simple constant folding in expressions:
1344 (2+3) --> (5).
1345
Raymond Hettingera422c342005-01-11 03:03:27 +00001346- set and frozenset objects can now be marshalled. SF #1098985.
1347
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001348- Bug #1077106: Poor argument checking could cause memory corruption
1349 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001350
Jeremy Hyltonab630502005-02-04 18:44:06 +00001351- The parser did not complain about future statements in illegal
1352 positions. It once again reports a syntax error if a future
1353 statement occurs after anything other than a doc string.
1354
Neil Schemenauercf52c072005-08-12 17:34:58 +00001355- Change the %s format specifier for str objects so that it returns a
1356 unicode instance if the argument is not an instance of basestring and
1357 calling __str__ on the argument returns a unicode instance.
1358
Tim Petersf4e69282006-02-27 17:15:31 +00001359- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1360 current thread state when the auto-GIL-state machinery knows about
1361 it (since the thread state is being deleted, continuing to remember it
1362 can't help, but can hurt if another thread happens to get created with
1363 the same thread id).
1364
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001365Extension Modules
1366-----------------
1367

Neal Norwitz10be10c2006-03-16 06:50:13 +00001381 util, whatsound, whrandom, zmod
1382
1383- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1384
1385- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001386 is deprecated. The undocumented re.engine variable no longer exists.
1387
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001388- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1389 SS2 (single-shift 2) escape sequences correctly.
1390
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001391- The unicodedata module was updated to the 4.1 version of the Unicode
1392 database. The 3.2 version is still available as unicodedata.db_3_2_0
1393 for applications that require this specific version (such as IDNA).
1394
Neal Norwitzb62c4332006-03-04 18:35:47 +00001395- The timing module is no longer built by default. It was deprecated
1396 in PEP 4 in Python 2.0 or earlier.
1397
Guido van Rossum1968ad32006-02-25 22:38:04 +00001398- Patch 1433928: Added a new type, defaultdict, to the collections module.
1399 This uses the new __missing__ hook behavior added to dict (see above).
1400
Georg Brandldbd83392006-02-20 09:42:33 +00001401- Bug #854823: socketmodule now builds on Sun platforms even when
1402 INET_ADDRSTRLEN is not defined.
1403
Georg Brandlf4f44152006-02-18 22:29:33 +00001404- Patch #1393157: os.startfile() now has an optional argument to specify
1405 a "command verb" to invoke on the file.
1406
Neal Norwitz082b2df2006-02-07 07:04:46 +00001407- Bug #876637, prevent stack corruption when socket descriptor

1409
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001410- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1411 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1412 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

1415 than the system default domain.
1416
Martin v. Löwis14694662006-02-03 12:54:16 +00001417- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1418 are reported, the limit on path name lengths is removed, and stat reports
1419 WindowsError now (instead of OSError).
1420
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001421- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001495- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1496 the request code argument, which results in more C-like behaviour
1497 for large or negative values.
1498
Tim Petersecc6e6a2005-07-10 22:30:55 +00001499- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1514
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001515- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001539- the cPickle module no longer accepts the deprecated None option in the
1540 args tuple returned by __reduce__().
1541
Raymond Hettingerb2594052004-12-05 09:25:51 +00001542- itertools.islice() now accepts None for the start and step arguments.
1543 This allows islice() to work more readily with slices:
1544 islice(s.start, s.stop, s.step)
1545

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001555- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1556 been renamed to have only a single underscore prefix. This was done to
1557 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001558
Nick Coghlan43832302006-04-23 17:04:07 +00001559- PEP 338: new module runpy defines a run_module function to support
1560 executing modules which provide access to source code or a code object
1561 via the PEP 302 import mechanisms.
1562
Anthony Baxter93f5b932006-04-03 08:05:07 +00001563- The email module's parsedate_tz function now sets the daylight savings
1564 flag to -1 (unknown) since it can't tell from the date whether it should

1571 in attribute values.
1572
Anthony Baxterc51ee692006-04-01 00:57:31 +00001573- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001574 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001575 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001576 module will not be built.
1577
Tim Petersc17976e2006-04-01 00:26:53 +00001578- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1579 aren't officially supported here, and trying to use them will probably
1580 raise an exception some day. But dicts have been allowed, and "mostly
1581 worked", so support for them won't go away without warning.
1582
Georg Brandl338ef7d2006-03-31 18:42:16 +00001583- Bug #1445068: getpass.getpass() can now be given an explicit stream
1584 argument to specify where to write the prompt.
1585
Georg Brandl22ec80b2006-03-31 18:25:44 +00001586- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1595 to make it easier to monitor when daemon threads have completed
1596 processing all enqueued tasks. Patch #1455676.
1597

1601
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001602- email 4.0 package now integrated. This is largely the same as the email 3.0
1603 package that was included in Python 2.3, except that PEP 8 module names are
1604 now used (e.g. mail.message instead of email.Message). The MIME classes
1605 have been moved to a subpackage (e.g. email.mime.text instead of
1606 email.MIMEText). The old names are still supported for now. Several
1607 deprecated Message methods have been removed and lots of bugs have been
1608 fixed. More details can be found in the email package documentation.
1609
Walter Dörwald40108c92006-03-27 08:15:44 +00001610- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1611 (a subclass of tuple) that provides incremental decoders and encoders
1612 (a way to use stateful codecs without the stream API). Python functions
1613 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1614 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1615 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001616
Walter Dörwald067db482006-03-15 22:17:27 +00001617- Patch #1359365: Calling next() on a closed StringIO.String object raises
1618 a ValueError instead of a StopIteration now (like file and cString.String do).
1619 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1620 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001621
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001622- A regrtest option -w was added to re-run failed tests in verbose mode.

1632
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001633- PEP 343: new module contextlib.py defines decorator @contextmanager
1634 and helpful context managers nested() and closing().
1635

Martin v. Löwis3e865952006-01-24 15:51:21 +00001670 specifications, raises IOErrors when proxies for unsupported protocols
1671 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001694 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1695 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1696 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1697 Ronald L. Rivest offered this advice for Python:
1698
1699 "The consensus of researchers in this area (at least as
1700 expressed at the NIST Hash Function Workshop 10/31/05),
1701 is that SHA-256 is a good choice for the time being, but
1702 that research should continue, and other alternatives may
1703 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001704
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001705- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl532efab2005-08-24 22:34:21 +00001750
Georg Brandlb9256022005-08-24 18:46:39 +00001751- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1752 ContentTooShortException, when the actually downloaded size does not
1753 match the Content-Length header.
1754
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00001755- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
1756
Martin v. Löwis56066d22005-08-24 07:38:12 +00001757- Bug #1178484: Return complete lines from codec stream readers
1758 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001759 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001760

1774
Georg Brandla4a8b822005-07-15 09:13:21 +00001775- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1776 parameter, but uses the usual "kwargs=None".
1777
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001778- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001779 Patch #1209527 (Contributed by Connelly).
1780
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001781- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1782 to W3C name (404 -> 'Not Found'). RFE #1216944.
1783
Georg Brandl9e43acf2005-07-04 17:16:07 +00001784- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1785 as this can cause problems with apps closing all file descriptors.
1786
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001787- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001788 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001789
Georg Brandl2f210b62005-06-26 22:09:06 +00001790- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
1791
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001792- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1793 error messages.

Georg Brandl379f99d2005-06-26 21:09:38 +00001795- Bug #1108948: Cookie.py produced invalid JavaScript code.
1796
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001797- The tokenize module now detects and reports indentation errors.
1798 Bug #1224621.
1799
Raymond Hettinger68c04532005-06-10 11:05:19 +00001800- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001801 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001802 the generate_tokens() function now accepts a callable argument that
1803 terminates by raising StopIteration.
1804
Georg Brandl9166e1a2005-06-04 09:20:03 +00001805- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1806
Georg Brandl268e61c2005-06-03 14:28:50 +00001807- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1808 component of the path.
1809
Skip Montanaro174dd222005-05-14 20:54:16 +00001810- Patch #1120353: The xmlrpclib module provides better, more transparent,
1811 support for datetime.{datetime,date,time} objects. With use_datetime set
1812 to True, applications shouldn't have to fiddle with the DateTime wrapper
1813 class at all.
1814
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001815- distutils.commands.upload was added to support uploading distribution
1816 files to PyPI.
1817
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001818- distutils.commands.register now encodes the data as UTF-8 before posting
1819 them to PyPI.
1820
Raymond Hettinger267b8682005-03-27 10:47:39 +00001821- decimal operator and comparison methods now return NotImplemented
1822 instead of raising a TypeError when interacting with other types. This
1823 allows other classes to implement __radd__ style methods and have them
1824 work as expected.
1825
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001826- Bug #1163325: Decimal infinities failed to hash. Attempting to
1827 hash a NaN raised an InvalidOperation instead of a TypeError.
1828
Tim Petersecc6e6a2005-07-10 22:30:55 +00001829- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001830 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1831

1863
Guido van Rossumd0641422005-02-03 15:01:24 +00001864- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1865 disables recursive traversal through instance attributes, which can
1866 be exploited in various ways.
1867
Tim Peterse3547fd2005-12-16 23:13:57 +00001868- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001869 flags on the HTTP listening socket.
1870
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001871- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1872 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1873
Fred Drakefbdeaad2006-07-29 16:56:15 +00001874- Patches #893642, #1039083: add allow_none, encoding arguments to
1875 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001876
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001877- Bug #1110478: Revert os.environ.update to do putenv again.
1878
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001879- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1880
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001881- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1882
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001883- Enhancements to the csv module:
1884
1885 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001886 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001887 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001888 + Dialect parameter parsing has been re-implemented to improve error
1889 reporting.
1890 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1891 dictates.
1892 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001893 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001894 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001895 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1896 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001897 + reader now allows \r characters to be quoted (previously it only allowed
1898 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001899 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001900 + Dialect classes passed to the module are no longer instantiated by
1901 the module before being parsed (the former validation scheme required
1902 this, but the mechanism was unreliable).
1903 + The dialect registry now contains instances of the internal
1904 C-coded dialect type, rather than references to python objects.
1905 + the internal c-coded dialect type is now immutable.
1906 + register_dialect now accepts the same keyword dialect specifications
1907 as the reader and writer, allowing the user to register dialects
1908 without first creating a dialect class.
1909 + a configurable limit to the size of parsed fields has been added -
1910 previously, an unmatched quote character could result in the entire
1911 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001912 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001913 the parser field size limit (returning the former limit). The initial
1914 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001915 + A line_num attribute has been added to the reader object, which tracks
1916 the number of lines read from the source iterator. This is not
1917 the same as the number of records returned, as records can span
1918 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001919 + reader and writer objects were not being registered with the cyclic-GC.
1920 This has been fixed.
1921
Brett Cannone6539c42005-01-08 02:43:53 +00001922- _DummyThread objects in the threading module now delete self.__block that is
1923 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1924 lock primitives tend to be limited in number and thus should not be wasted on
1925 a _DummyThread object. Fixes bug #1089632.
1926
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001927- The imghdr module now detects Exif files.
1928
Raymond Hettinger6065d322004-12-20 23:51:53 +00001929- StringIO.truncate() now correctly adjusts the size attribute.
1930 (Bug #951915).
1931
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001932- locale.py now uses an updated locale alias table (built using
1933 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1934 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001935 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001936
Raymond Hettinger3557f422004-12-07 12:02:02 +00001937- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1938
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001939- the pickle module no longer accepts the deprecated None option in the
1940 args tuple returned by __reduce__().
1941
Brett Cannon84667c02004-12-07 03:25:18 +00001942- optparse now optionally imports gettext. This allows its use in setup.py.
1943
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001944- the pickle module no longer uses the deprecated bin parameter.
1945
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001946- the shelve module no longer uses the deprecated binary parameter.
1947
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001948- the pstats module no longer uses the deprecated ignore() method.
1949
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001950- the filecmp module no longer uses the deprecated use_statcache argument.
1951
Raymond Hettinger664347b2004-12-04 21:21:53 +00001952- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1953 extended or overridden by subclasses. Formerly, the subclassed method would
1954 be ignored by the rest of the module. (Bug #1078905).
1955
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001956- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001957 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001958
Walter Dörwald36733692004-12-22 12:50:50 +00001959- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1960 once when a size argument is given. This prevents a buffer overflow in the
1961 tokenizer with very long source lines.
1962
Barry Warsaw538561e2006-01-01 21:48:54 +00001963- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1964 immediately after creating the object, without any intervening
1965 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001966
Skip Montanaro05885812005-01-16 20:48:27 +00001967- The reconvert.quote function can now emit triple-quoted strings. The
1968 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001969
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001970- ``UserString.MutableString`` now supports negative indices in
1971 ``__setitem__`` and ``__delitem__``
1972
Greg Ward40407942005-03-05 02:53:17 +00001973- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1974 correctly.
1975
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001976- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1977 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1978 character even if the user has passed a size parameter to get a proper
1979 line ending. Remove the special handling of a "\r\n" that has been split
1980 between two lines.
1981
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001982- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1983 about illegal code points. The codec now supports PEP 293 style error
1984 handlers.
1985
Walter Dörwald78a78b02005-09-01 12:04:29 +00001986- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001987 from the input stream, so that the output is a byte string in the correct
1988 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001989
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001990- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1991 considering it exactly like a '*'.
1992
Walter Dörwald007f8df2005-10-09 19:42:27 +00001993- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1994 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001995
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001996- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1997
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001998- Patch #1413711: Certain patterns of differences were making difflib
1999 touch the recursion limit.
2000
Walter Dörwald58917a62006-03-31 15:26:22 +00002001- Bug #947906: An object oriented interface has been added to the calendar
2002 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002003 called as a script (e.g. via ``python -mcalendar``). Localized month and
2004 weekday names can be ouput (even if an exotic encoding is used) using
2005 special classes that use unicode.

2008-----
2009
Neal Norwitz602d3392006-03-31 08:21:40 +00002010- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2011 by using -mieee gcc option.
2012

2014
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002015- Build support for Win64-AMD64 was added.
2016
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002017- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2018
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002019- Patch #881820: look for openpty and forkpty also in libbsd.
2020
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002021- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2022 The zlib module is now builtin on Windows.
2023
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002024- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2025
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002026- Bug #1189330: configure did not correctly determine the necessary
2027 value of LINKCC if python was built with GCC 4.0.
2028
Trent Mick8321b422005-07-26 02:29:21 +00002029- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2030 vulnerability in zlib 1.2.1 and 1.2.2.
2031
Brett Cannon08cd5982005-04-24 22:26:38 +00002032- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2033 flags that change binary compatibility. Changes were also made to
2034 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002035 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002036
Bob Ippolitoed233462005-03-29 13:47:59 +00002037- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2038 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2039 no longer exists). This configure patch makes things right.
2040
Martin v. Löwise2713be2005-03-08 15:03:08 +00002041- Bug #1158607: Build with --disable-unicode again.
2042
Brett Cannon46d96232005-02-16 00:07:19 +00002043- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2044 defined. Discovered as a result of not being able to build on OS X.
2045
Brett Cannon516592f2004-12-07 00:42:59 +00002046- setup.py now uses the directories specified in LDFLAGS using the -L option
2047 and in CPPFLAGS using the -I option for adding library and include
2048 directories, respectively, for compiling extension modules against. This has
2049 led to the core being compiled using the values in CPPFLAGS. It also removes
2050 the need for the special-casing of both DarwinPorts and Fink for darwin since
2051 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2052 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2053 Fink, ``-I/opt/local/include`` for DarwinPorts).
2054
Brett Cannon43802422005-02-10 20:48:03 +00002055- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2056 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2057 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2058 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002060C API
2061-----
2062
Tim Petersc9d78aa2006-03-26 23:27:58 +00002063- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2064 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2065 is obtained via the ``PyObject_`` family, it must be released via the
2066 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2067 always been officially true, but when Python's small-object allocator was
2068 introduced, an attempt was made to cater to a few extension modules
2069 discovered at the time that obtained memory via ``PyObject_New`` but
2070 released it via ``PyMem_DEL``. It's years later, and if such code still
2071 exists it will fail now (probably with segfaults, but calling wrong
2072 low-level memory management functions can yield many symptoms).
2073
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002074- Added a C API for set and frozenset objects.
2075
Raymond Hettinger66517482004-12-03 11:45:13 +00002076- Removed PyRange_New().
2077
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002078- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2079 mapping argument now. This string is used as a mapping table. Byte values
2080 greater than the length of the string and 0xFFFE are treated as undefined
2081 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002087- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002088
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002089- Patch #1276356: New resource "urlfetch" is implemented. This enables
2090 even impatient people to run tests that require remote files.
