Marc-André Lemburg040f76b2006-08-14 10:55:19 +000015- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000016 compared equal or unequal to a string and a UnicodeDecodeError
17 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +000018
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000019 Instead, the equal (==) and unequal (!=) comparison operators will
20 now issue a UnicodeWarning and interpret the two objects as
21 unequal. The UnicodeWarning can be filtered as desired using
22 the warning framework, e.g. silenced completely, turned into an
23 exception, logged, etc.
24
25 Note that compare operators other than equal and unequal will still
26 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +000027
Marc-André Lemburg757ea272006-08-14 11:44:34 +000028- Fix segfault when doing string formatting on subclasses of long.
29
30- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
31 with new-style classes.
32
33- Fix bug related to __len__ functions returning negative values with
34 classic classes.
35
36- Patch #1538606, Fix __index__() clipping. There were some problems
37 discovered with the API and how integers that didn't fit into Py_ssize_t
38 were handled. This patch attempts to provide enough alternatives
39 to effectively use __index__.
40
Martin v. Löwisab2f8f72006-08-09 07:57:39 +000041- Bug #1536021: __hash__ may now return long int; the final hash
42 value is obtained by invoking hash on the long int.
43
Thomas Hellerab1049c2006-08-08 17:37:00 +000044- Bug #1536786: buffer comparison could emit a RuntimeWarning.
45
Georg Brandl7e3ba2a2006-08-06 08:23:54 +000046- Bug #1535165: fixed a segfault in input() and raw_input() when
47 sys.stdin is closed.
48
Thomas Heller74d36f02006-08-04 18:17:40 +000049- On Windows, the PyErr_Warn function is now exported from
50 the Python dll again.
51
Neal Norwitz4ffedad2006-08-04 04:58:47 +000052- Bug #1191458: tracing over for loops now produces a line event
53 on each iteration. Fixing this problem required changing the .pyc
54 magic number. This means that .pyc files generated before 2.5c1
55 will be regenerated.
56
Neal Norwitz0cbd8052006-08-04 05:09:28 +000057- Bug #1333982: string/number constants were inappropriately stored
58 in the byte code and co_consts even if they were not used, ie
59 immediately popped off the stack.
60
Georg Brandle9462c72006-08-04 18:03:37 +000061- Fixed a reference-counting problem in property().
62
Neal Norwitzff4b63b2006-08-04 04:50:21 +000063
64Library
65-------
66
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000067- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +000068 an exception.
69
Anthony Baxter58179592006-08-16 13:08:25 +000070- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000071 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +000072 workarounds for clocks with low resolution, to stop the code yielding
73 duplicate UUIDs.
74
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +000075- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
76 before raising SystemExit, allowing IDLE to honor quit() and exit().
77
Neal Norwitzbf8c1952006-08-15 04:14:57 +000078- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
79
Georg Brandl7a1af772006-08-14 21:55:28 +000080- Patch #1536071: trace.py should now find the full module name of a
81 file correctly even on Windows.
82
Georg Brandl0a7d1bb2006-08-11 07:26:10 +000083- logging's atexit hook now runs even if the rest of the module has
84 already been cleaned up.
85
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000086- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +000087
Neal Norwitzff4b63b2006-08-04 04:50:21 +000088- Bug #1531405, format_exception no longer raises an exception if
89 str(exception) raised an exception.
90
Neil Schemenauer06ded092006-08-04 16:20:30 +000091- Fix a bug in the ``compiler`` package that caused invalid code to be
92 generated for nested functions.
93
Neal Norwitzff4b63b2006-08-04 04:50:21 +000094

Georg Brandl3335a7a2006-08-14 21:42:55 +0000100- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
101 raises the correct exceptions.
102
Thomas Heller1ce433e2006-08-14 16:20:04 +0000103- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
104 '-no-stack-protector' compiler flag for OpenBSD has been removed.
105
Thomas Heller86720042006-08-14 11:17:48 +0000106- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
107 uses the _as_parameter_ attribute when objects are passed to foreign
108 function calls. The ctypes version number was changed to 1.0.1.
109
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000110- Bug #1530559, struct.pack raises TypeError where it used to convert.
111 Passing float arguments to struct.pack when integers are expected
112 now triggers a DeprecationWarning.
113
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000114

136-----
137
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000138- Bug #1535502, build _hashlib on Windows, and use masm assembler
139 code in OpenSSL.
140
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000141- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Fred Drake53912162006-07-29 13:22:49 +0000161What's New in Python 2.5 beta 3?
162================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000163
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000164*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000165
166Core and builtins
167-----------------
168
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000169- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000170 returned a long (see PEP 353).
171
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000172- Bug #1515471: string.replace() accepts character buffers again.
173
Neal Norwitz07aadb12006-07-30 06:55:48 +0000174- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
175 This provides the proper warning for struct.pack().
176 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
177
Neal Norwitz0d62a062006-07-30 06:53:31 +0000178- Patch #1531113: Fix augmented assignment with yield expressions.
179 Also fix a SystemError when trying to assign to yield expressions.
180
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000181- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
182 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
183 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
184 excessive filesystem operations during imports.
185
Tim Petersbc24eee2006-07-27 01:14:53 +0000186- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
187 operations on signed longs that are formally undefined by C.
188 Unfortunately, at least one compiler now cares about that, so complicated
189 the code to make that compiler happy again.
190
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000191- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
192
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000193- Patch #1232023: Stop including current directory in search
194 path on Windows.
195
Neal Norwitze1fdb322006-07-21 05:32:28 +0000196- Fix some potential crashes found with failmalloc.
197
Neal Norwitze7563102006-07-17 01:00:16 +0000198- Fix warnings reported by Klocwork's static analysis tool.
199
Neal Norwitz84be93b2006-07-16 01:50:38 +0000200- Bug #1512814, Fix incorrect lineno's when code within a function
201 had more than 255 blank lines.
202
Georg Brandl9dceedb2006-07-12 15:31:17 +0000203- Patch #1521179: Python now accepts the standard options ``--help`` and
204 ``--version`` as well as ``/?`` on Windows.
205
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000206- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000207 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000208 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000209
Tim Peters112aad32006-07-19 00:03:19 +0000210- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000211 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000212 new ``sys._current_frames()`` returns a dictionary with one entry,
213 mapping the faux "thread id" 0 to the current frame.
214
Ronald Oussoren3075e162006-07-25 20:28:55 +0000215- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000216
Ronald Oussoren3075e162006-07-25 20:28:55 +0000217
Neal Norwitza1f10902006-07-12 07:28:29 +0000218Library
219-------
220
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000221- Correction of patch #1455898: In the mbcs decoder, set final=False
222 for stream decoder, but final=True for the decode function.
223
Georg Brandl07fec3a2006-08-01 18:49:24 +0000224- os.urandom no longer masks unrelated exceptions like SystemExit or
225 KeyboardInterrupt.
226
Tim Peters4643c2f2006-08-10 22:45:34 +0000227- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000228 shutil.copytree on Windows
229
Georg Brandle34ac7c2006-07-30 11:07:23 +0000230- Bug #1002398: The documentation for os.path.sameopenfile now correctly
231 refers to file descriptors, not file objects.
232
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000233- The renaming of the xml package to xmlcore, and the import hackery done
234 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000235 #1513611, and probably others.
236
Georg Brandledd9b0d2006-07-29 09:33:26 +0000237- Bug #1441397: The compiler module now recognizes module and function
238 docstrings correctly as it did in Python 2.4.
239
Tim Peters6f681472006-07-27 23:44:37 +0000240- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
241 lost that tests are sorted by name before being run. This rarely
242 matters for well-written tests, but can create baffling symptoms if
243 side effects from one test to the next affect outcomes. ``DocTestFinder``
244 has been changed to sort the list of tests it returns.
245
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000246- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000247 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000248
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000249- Bug #978833: Really close underlying socket in _socketobject.close.
250
Georg Brandl0619a322006-07-26 07:40:17 +0000251- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
252 with title().
253
Georg Brandlcf0c1722006-07-26 07:23:32 +0000254- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
255 to recursive calls and call it with the failing package name.
256
Martin v. Löwis0b483032006-07-25 09:53:12 +0000257- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
258
Georg Brandlc13c34c2006-07-24 14:09:56 +0000259- Patch #1515343: Fix printing of deprecated string exceptions with a
260 value in the traceback module.
261
Greg Ward48fae7a2006-07-23 16:05:51 +0000262- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
263
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000264- Patch #1524429: Use repr() instead of backticks in Tkinter again.
265
Brett Cannoncaebe222006-07-18 04:41:36 +0000266- Bug #1520914: Change time.strftime() to accept a zero for any position in its
267 argument tuple. For arguments where zero is illegal, the value is forced to
268 the minimum value that is correct. This is to support an undocumented but
269 common way people used to fill in inconsequential information in the time
270 tuple pre-2.4.
271
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000272- Patch #1220874: Update the binhex module for Mach-O.
273
Barry Warsawb110bad2006-07-21 14:51:07 +0000274- The email package has improved RFC 2231 support, specifically for
275 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
276 (name*0=<blah>) parameter continuations. This may change the types of
277 values returned from email.message.Message.get_param() and friends.
278 Specifically in some cases where non-encoded continuations were used,
279 get_param() used to return a 3-tuple of (None, None, string) whereas now it
280 will just return the string (since non-encoded continuations don't have
281 charset and language parts).
282
283 Also, whereas % values were decoded in all parameter continuations, they are
284 now only decoded in encoded parameter parts.
285
Ronald Oussoren3075e162006-07-25 20:28:55 +0000286- Bug #1517990: IDLE keybindings on MacOS X now work correctly
287
288- Bug #1517996: IDLE now longer shows the default Tk menu when a
289 path browser, class browser or debugger is the frontmost window on MacOS X
290
Barry Warsaw00decd72006-07-27 23:43:15 +0000291- Patch #1520294: Support for getset and member descriptors in types.py,
292 inspect.py, and pydoc.py. Specifically, this allows for querying the type
293 of an object against these built-in types and more importantly, for getting
294 their docstrings printed in the interactive interpreter's help() function.

299
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000300- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
301 a socket operation on a socket with a timeout, the exception will be
302 caught correctly. Previously, the exception was not caught.
303
Thomas Heller1393d6a2006-07-28 21:43:20 +0000304- Patch #1529514: The _ctypes extension is now compiled on more
305 openbsd target platforms.
306
Tim Peters9cab5932006-07-28 00:30:00 +0000307- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
308 a memory leak, affecting pickles and deep copies.
309
Tim Petersbc24eee2006-07-27 01:14:53 +0000310- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

312
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000313- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
314
Thomas Hellerce049a02006-07-14 17:51:14 +0000315- Patch #1521817: Index range checking on ctypes arrays containing
316 exactly one element enabled again. This allows iterating over these
317 arrays, without the need to check the array size before.
318
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000319- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000320 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000321 /dev/null in certain cases; this is now fixed.
322
Thomas Heller47d7a062006-07-12 08:43:47 +0000323- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
324 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000325
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000326- Because of a misspelled preprocessor symbol, ctypes was always
327 compiled without thread support; this is now fixed.
328
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000329- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
330 methods now allow their database parameter to be None as the
331 sleepycat API allows.
332
Matt Flemingec926502006-07-28 11:27:27 +0000333- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
334 bluetooth API compared with Linux and FreeBSD.
335
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000336Tests
337-----
338
339- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
340 how long the test file should take to play. Now accepts taking 2.93 secs
341 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
342
Georg Brandl4793aa32006-07-28 18:31:39 +0000343- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
344 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
345 run via ``regrtest.py``. Now they do.

354
355- PythonLauncher now works correctly when the path to the script contains
356 characters that are treated specially by the shell (such as quotes).
357
358- Bug #1527397: PythonLauncher now launches scripts with the working directory
359 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000360 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000361 expect.

369Core and builtins
370-----------------
371
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000372- Bug #1441486: The literal representation of -(sys.maxint - 1)
373 again evaluates to a int object, not a long.
374
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000375- Bug #1501934: The scope of global variables that are locally assigned
376 using augmented assignment is now correctly determined.
377
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000378- Bug #927248: Recursive method-wrapper objects can now safely
379 be released.
380
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000381- Bug #1417699: Reject locale-specific decimal point in float()
382 and atof().
383
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000384- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
385 omit a default "error" argument for NULL pointer. This allows
386 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000387
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000388- Bug #1519018: 'as' is now validated properly in import statements.
389
Neal Norwitz28746ab2006-07-09 22:14:42 +0000390- On 64 bit systems, int literals that use less than 64 bits are
391 now ints rather than longs.
392
Neal Norwitzed657552006-07-10 00:04:44 +0000393- Bug #1512814, Fix incorrect lineno's when code at module scope
394 started after line 256.
395
Tim Peters32a83612006-07-10 21:08:24 +0000396- New function ``sys._current_frames()`` returns a dict mapping thread
397 id to topmost thread stack frame. This is for expert use, and is
398 especially useful for debugging application deadlocks. The functionality
399 was previously available in Fazal Majid's ``threadframe`` extension
400 module, but it wasn't possible to do this in a wholly threadsafe way from
401 an extension.

410
Tim Peters32a83612006-07-10 21:08:24 +0000411- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000412 environment variable to be set in order to the SDK environment
413 for finding the compiler, include files, etc.

418
Thomas Woutersadd19112006-07-05 11:03:49 +0000419- string.Template() now correctly handles tuple-values. Previously,
420 multi-value tuples would raise an exception and single-value tuples would
421 be treated as the value they contain, instead.
422
Martin v. Löwisede77f52006-07-03 13:01:35 +0000423- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
424 even if some data are received.

430 degrees and radians.
431
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000432- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000433 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000434

436 is created.
437
Martin v. Löwis7596e832006-07-01 15:33:37 +0000438- Bug #1513223: .close() of a _socketobj now releases the underlying
439 socket again, which then gets closed as it becomes unreferenced.
440
Fred Drake10497c82006-06-29 02:57:48 +0000441- Bug #1504333: Make sgmllib support angle brackets in quoted
442 attribute values.
443
444- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
445 sgmllib ('[' and ']' were not accepted).
446
Georg Brandl1be63af2006-06-28 20:23:25 +0000447- Fix a bug in the turtle module's end_fill function.
448
Brett Cannon53ab5b72006-06-22 16:49:14 +0000449- Bug #1510580: The 'warnings' module improperly required that a Warning
450 category be either a types.ClassType and a subclass of Warning. The proper
451 check is just that it is a subclass with Warning as the documentation states.
452
Georg Brandlad29e632006-06-21 17:45:17 +0000453- The compiler module now correctly compiles the new try-except-finally
454 statement (bug #1509132).
455
Neal Norwitz60373cd2006-06-22 06:30:50 +0000456- The wsgiref package is now installed properly on Unix.
457
Vinay Sajip28e57612006-07-01 10:45:20 +0000458- A bug was fixed in logging.config.fileConfig() which caused a crash on
459 shutdown when fileConfig() was called multiple times.
460
Gerhard Häring762fbd32006-07-02 17:48:30 +0000461- The sqlite3 module did cut off data from the SQLite database at the first
462 null character before sending it to a custom converter. This has been fixed
463 now.
464
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000465Extension Modules
466-----------------
467
Tim Peters112aad32006-07-19 00:03:19 +0000468- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
469 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
470 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000471
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000472- Assigning None to pointer type fields in ctypes structures possible
473 overwrote the wrong fields, this is fixed now.
474
475- Fixed a segfault in _ctypes when ctypes.wintypes were imported
476 on non-Windows platforms.
477
478- Bug #1518190: The ctypes.c_void_p constructor now accepts any
479 integer or long, without range checking.
480
481- Patch #1517790: It is now possible to use custom objects in the ctypes
482 foreign function argtypes sequence as long as they provide a from_param
483 method, no longer is it required that the object is a ctypes type.
484
485- The '_ctypes' extension module now works when Python is configured
486 with the --without-threads option.
487
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000488- Bug #1513646: os.access on Windows now correctly determines write
489 access, again.
490
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000491- Bug #1512695: cPickle.loads could crash if it was interrupted with
492 a KeyboardInterrupt.
493
Neal Norwitza12aa882006-07-06 06:45:08 +0000494- Bug #1296433: parsing XML with a non-default encoding and
495 a CharacterDataHandler could crash the interpreter in pyexpat.

500-----
501
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000502- Automate Windows build process for the Win64 SSL module.
503
Tim Peters32a83612006-07-10 21:08:24 +0000504- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000505 Previously, the slight difference could cause compilation errors of the
506 'zlib' module on systems with more than one version of zlib.
507
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000508- The MSI compileall step was fixed to also support a TARGETDIR
509 with spaces in it.
510
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000511- Bug #1517388: sqlite3.dll is now installed on Windows independent
512 of Tcl/Tk.
513
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000514- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000515 trying to be installed even though it's empty.

539Core and builtins
540-----------------
541
Georg Brandla56b9152006-06-19 06:35:54 +0000542- Patch #1507676: Error messages returned by invalid abstract object operations
543 (such as iterating over an integer) have been improved and now include the
544 type of the offending object to help with debugging.
545
Brett Cannonea3912b2006-06-13 21:46:41 +0000546- Bug #992017: A classic class that defined a __coerce__() method that returned
547 its arguments swapped would infinitely recurse and segfault the interpreter.
548
Neal Norwitz909eb122006-06-12 02:13:21 +0000549- Fix the socket tests so they can be run concurrently.
550
Neal Norwitzb9845e72006-06-12 02:11:18 +0000551- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000552 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000553
Brett Cannon22565aa2006-06-09 22:31:23 +0000554- Bug #532646: object.__call__() will continue looking for the __call__
555 attribute on objects until one without one is found. This leads to recursion
556 when you take a class and set its __call__ attribute to an instance of the
557 class. Originally fixed for classic classes, but this fix is for new-style.
558 Removes the infinite_rec_3 crasher.
559
Georg Brandl24250812006-06-09 18:45:48 +0000560- The string and unicode methods startswith() and endswith() now accept
561 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
562
Brett Cannonde3b0522006-06-08 17:00:45 +0000563- Buffer objects, at the C level, never used the char buffer
564 implementation even when the char buffer for the wrapped object was
565 explicitly requested (originally returned the read or write buffer).
566 Now a TypeError is raised if the char buffer is not present but is
567 requested.
568
Georg Brandlddbaa662006-06-04 21:56:52 +0000569- Patch #1346214: Statements like "if 0: suite" are now again optimized
570 away like they were in Python 2.4.
571
Georg Brandlb7c8f542006-05-27 12:30:25 +0000572- Builtin exceptions are now full-blown new-style classes instead of
573 instances pretending to be classes, which speeds up exception handling
574 by about 80% in comparison to 2.5a2.
575
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000576- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
577 Unicode 4.1.
578
Georg Brandlf4ef1162006-05-26 18:03:31 +0000579- Patch #921466: sys.path_importer_cache is now used to cache valid and
580 invalid file paths for the built-in import machinery which leads to
581 fewer open calls on startup.
582
Tim Peters696cf432006-05-24 21:10:40 +0000583- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
584 of-2 bases. The largest speedup is for inputs with about 1000 decimal
585 digits. Conversion from non-power-of-2 bases remains quadratic-time in
586 the number of input digits (it was and remains linear-time for bases
587 2, 4, 8, 16 and 32).
588
Tim Petersb713ec22006-05-23 18:45:30 +0000589- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
590 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
591 an integer close to ``sys.maxint``. This was repaired by patch
592 #1335972, which also gives a nice speedup.
593
Richard Jonescebbefc2006-05-23 18:28:17 +0000594- Patch #1337051: reduced size of frame objects.
595
596- PyErr_NewException now accepts a tuple of base classes as its
597 "base" parameter.
598
Richard Jones7c88dcc2006-05-23 10:37:38 +0000599- Patch #876206: function call speedup by retaining allocated frame
600 objects.
601
Georg Brandl7b90e162006-05-18 07:01:27 +0000602- Bug #1462152: file() now checks more thoroughly for invalid mode
603 strings and removes a possible "U" before passing the mode to the
604 C library function.
605
Neal Norwitz1004a532006-05-15 07:17:23 +0000606- Patch #1488312, Fix memory alignment problem on SPARC in unicode
607
Neal Norwitz373f0a72006-05-15 07:04:36 +0000608- Bug #1487966: Fix SystemError with conditional expression in assignment
609
Martin v. Löwis879768d2006-05-11 13:28:43 +0000610- WindowsError now has two error code attributes: errno, which carries
611 the error values from errno.h, and winerror, which carries the error
612 values from winerror.h. Previous versions put the winerror.h values
613 (from GetLastError()) into the errno attribute.
614
Martin v. Löwis77736712006-05-04 05:51:03 +0000615- Patch #1475845: Raise IndentationError for unexpected indent.
616
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000617- Patch #1479181: split open() and file() from being aliases for each other.
618
Tim Peters44bd9862006-06-01 13:49:23 +0000619- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
620 methods were always silently ignored by dictionaries when comparing keys.
621 They are now passed through (except when using the C API function
622 ``PyDict_GetItem()``, whose semantics did not change).
623
624- Bug #1456209: In some obscure cases it was possible for a class with a
625 custom ``__eq__()`` method to confuse dict internals when class instances
626 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
627 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000629Extension Modules
630-----------------
631
Trent Mick960a3f82006-06-28 20:30:41 +0000632- Bug #1295808: expat symbols should be namespaced in pyexpat
633
634- Patch #1462338: Upgrade pyexpat to expat 2.0.0
635
Brett Cannon6ee7d012006-06-08 16:23:04 +0000636- Change binascii.hexlify to accept a read-only buffer instead of only a char
637 buffer and actually follow its documentation.
638
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000639- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
640
Nick Coghlanc649ec52006-05-29 12:43:05 +0000641- Patch #1478788 (modified version): The functional extension module has
642 been renamed to _functools and a functools Python wrapper module added.
643 This provides a home for additional function related utilities that are
644 not specifically about functional programming. See PEP 309.
645
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000646- Patch #1493701: performance enhancements for struct module.
647
Georg Brandl378d5922006-05-17 14:26:50 +0000648- Patch #1490224: time.altzone is now set correctly on Cygwin.
649
Georg Brandl8d3342b2006-05-16 07:38:27 +0000650- Patch #1435422: zlib's compress and decompress objects now have a
651 copy() method.
652
Andrew MacIntyre92913322006-06-13 15:04:24 +0000653- Patch #1454481: thread stack size is now tunable at runtime for thread
654 enabled builds on Windows and systems with Posix threads support.
655
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000656- On Win32, os.listdir now supports arbitrarily-long Unicode path names
657 (up to the system limit of 32K characters).
658
659- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
660 As a result, these functions now raise WindowsError instead of OSError.
661
Tim Peters7a822da2006-05-25 21:50:17 +0000662- ``time.clock()`` on Win64 should use the high-performance Windows
663 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
664 Windows platforms).
665
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000666- Calling Tk_Init twice is refused if the first call failed as that
667 may deadlock.
668
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000669- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
670 accept it without potentially using an uninitialized pointer.
671
672- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
673 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
674 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000675
Gregory P. Smith372b5832006-06-05 18:48:21 +0000676- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000677 [pybsddb project SF patch number 1466734]
678
Gregory P. Smith372b5832006-06-05 18:48:21 +0000679- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
680 parameter is supplied. [SF pybsddb bug #1477863]
681
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000682- bsddb: the __len__ method of a DB object has been fixed to return correct
683 results. It could previously incorrectly return 0 in some cases.
684 Fixes SF bug 1493322 (pybsddb bug 1184012).
685
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000686- bsddb: the bsddb.dbtables Modify method now raises the proper error and
687 aborts the db transaction safely when a modifier callback fails.
688 Fixes SF python patch/bug #1408584.
689
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000690- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000691 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000692 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
693 database calls that would previously deadlock. [SF python bug #775414]
694
Vinay Sajip28e57612006-07-01 10:45:20 +0000695- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000696
Walter Dörwald4994d952006-06-19 08:07:50 +0000697- Patch #1506645: add Python wrappers for the curses functions
698 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000699

702
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000703- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
704 functions.
705
Martin v. Löwis3798da02006-06-17 18:44:27 +0000706- Patch #812986: Update turtle output even if not tracing.
707
Vinay Sajip28e57612006-07-01 10:45:20 +0000708- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000709 Tkinter.BaseWidget.
710
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000711- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
712
Martin v. Löwis337487e2006-06-17 09:15:14 +0000713- Patch #763580: Add name and value arguments to Tkinter variable
714 classes.
715
Georg Brandl83cc0d02006-06-14 08:50:03 +0000716- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
717 mime.types file for determining MIME types.
718
Georg Brandl2605ca82006-06-14 06:08:31 +0000719- Bug #1339007: Shelf objects now don't raise an exception in their
720 __del__ method when initialization failed.
721
Martin v. Löwisd8251432006-06-14 05:21:04 +0000722- Patch #1455898: The MBCS codec now supports the incremental mode for
723 double-byte encodings.
724
Tim Peters43898b42006-06-14 04:09:25 +0000725- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
726 guarantee that adjacent triples in the return list always describe
727 non-adjacent blocks. Previously, a pair of matching blocks could end
728 up being described by multiple adjacent triples that formed a partition
729 of the matching pair.
730
Greg Ward0e0c9f42006-06-11 16:24:11 +0000731- Bug #1498146: fix optparse to handle Unicode strings in option help,
732 description, and epilog.
733
Greg Wardd1c797e2006-06-11 14:42:41 +0000734- Bug #1366250: minor optparse documentation error.
735
Greg Ward7f547402006-06-11 00:40:49 +0000736- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
737 clarify docs.
738
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000739- The wsgiref package has been added to the standard library.
740
Nick Coghlan676725d2006-06-08 13:54:49 +0000741- The functions update_wrapper() and wraps() have been added to the functools
742 module. These make it easier to copy relevant metadata from the original
743 function when writing wrapper functions.
744
Tim Petersd6a9eef2006-06-05 01:48:21 +0000745- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
746 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000747
Martin v. Löwis3f767792006-06-04 19:36:28 +0000748- Patch #1359618: Speed up charmap encoder by using a trie structure
749 for lookup.
750
Tim Petersd609b1a2006-06-02 23:22:51 +0000751- The functions in the ``pprint`` module now sort dictionaries by key
752 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
753 if and only if its display required more than one line, although that
754 wasn't documented. The new behavior increases predictability; e.g.,
755 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
756
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000757- Patch #1497027: try HTTP digest auth before basic auth in urllib2
758 (thanks for J. J. Lee).
759
Georg Brandl2b330372006-05-28 20:23:12 +0000760- Patch #1496206: improve urllib2 handling of passwords with respect to
761 default HTTP and HTTPS ports.
762
George Yoshidaf3c65de2006-05-28 16:39:09 +0000763- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
764
Bob Ippolito7298f272006-05-23 18:43:47 +0000765- Patch #1281707: speed up gzip.readline.
766
Georg Brandlb89316f2006-05-17 15:51:16 +0000767- Patch #1180296: Two new functions were added to the locale module:
768 format_string() to get the effect of "format % items" but locale-aware,
769 and currency() to format a monetary number with currency sign.
770
Georg Brandle3a25832006-05-17 14:56:04 +0000771- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
772 and several features added, such as speed and geometry control.
773
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000774- Patch #1488881: add support for external file objects in bz2 compressed
775 tarfiles.
776
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000777- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
778 stdout arguments, making it possible to redirect input and output
779 for remote debugging.
780
781- Patch #1484695: Update the tarfile module to version 0.8. This fixes
782 a couple of issues, notably handling of long file names using the
783 GNU LONGNAME extension.
784
785- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
786 new flag when ``name`` is already the name of an option flag.
787
788- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
789 package.
790
791- Patch #1472854: make the rlcompleter.Completer class usable on non-
792 UNIX platforms.
793
794- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
795
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000796- Bug #1472827: correctly escape newlines and tabs in attribute values in
797 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000827What's New in Python 2.5 alpha 2?
828=================================
829
830*Release date: 27-APR-2006*
831
832Core and builtins
833-----------------
834
Thomas Heller1b046642006-04-18 18:51:06 +0000835- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
836 by converting these apis from macros into exported functions again:
837
838 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
839 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
840 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
841 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
842 PyRun_String Py_CompileString
843
Martin v. Löwis45294a92006-04-18 06:24:08 +0000844- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
845
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000846- All uses of PyStructSequence_InitType have been changed to initialize
847 the type objects only once, even if the interpreter is initialized
848 multiple times.
849
Neal Norwitz61546162006-04-14 05:20:28 +0000850- Bug #1454485, array.array('u') could crash the interpreter. This was
851 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
852 to unicode when it didn't make sense. 'u#' now requires a unicode string.
853
854- Py_UNICODE is unsigned. It was always documented as unsigned, but
855 due to a bug had a signed value in previous versions.
856
Tim Peters3a5e8b12006-04-11 01:44:07 +0000857- Patch #837242: ``id()`` of any Python object always gives a positive
858 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
859 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000860 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000861 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000862
Tim Peters3a5e8b12006-04-11 01:44:07 +0000863 def __hash__(self):
864 return id(self) # WRONG
865
866 because a hash result must be a (short) Python int but it was always
867 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000868 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000869 was always usable as a hash value before this patch. That's no longer
870 necessarily so.
871
872- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000873 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000874 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000875 #1454844)
876
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000877- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
878 involving generators that have paused outside of any ``try`` or ``with``
879 blocks. (In 2.5a1, a paused generator that was part of a reference
880 cycle could not be garbage collected, regardless of whether it was
881 paused in a ``try`` or ``with`` block.)

884-----------------
885

887 is a macro.
888
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000889- Bug #1467952: os.listdir() now correctly raises an error if readdir()
890 fails with an error condition.
891
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000892- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
893
894- Bug #1117761: bsddb.*open() no longer raises an exception when using
895 the cachesize parameter.
896
897- Bug #1149413: bsddb.*open() no longer raises an exception when using
898 a temporary db (file=None) with the 'n' flag to truncate on open.
899
900- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
901 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000902
Armin Rigoa9017c32006-04-19 11:50:27 +0000903- Patch #1062014: AF_UNIX sockets under Linux have a special
904 abstract namespace that is now fully supported.
905
Anthony Baxter51bcb682006-04-05 14:51:42 +0000906Library
907-------
908
Peter Astrand7d1d4362006-07-14 14:04:45 +0000909- Bug #1223937: subprocess.CalledProcessError reports the exit status
910 of the process using the returncode attribute, instead of
911 abusing errno.
912
Tim Peters711bf302006-04-25 03:31:36 +0000913- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
914 a doctest to be skipped (the code is not run, and the expected output
915 or exception is ignored).
916
Nick Coghlanda2268f2006-04-24 04:37:15 +0000917- Fixed contextlib.nested to cope with exceptions being raised and
918 caught inside exit handlers.
919
Greg Wardab05edc2006-04-23 03:47:58 +0000920- Updated optparse module to Optik 1.5.1 (allow numeric constants in
921 hex, octal, or binary; add ``append_const`` action; keep going if
922 gettext cannot be imported; added ``OptionParser.destroy()`` method;
923 added ``epilog`` for better help generation).
924
Tim Peters21fbd572006-04-21 21:18:10 +0000925- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
926 called from a thread spawned as a side effect of importing a module.
927
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000928- The pydoc module now supports documenting packages contained in
929 .zip or .egg files.
930
931- The pkgutil module now has several new utility functions, such
932 as ``walk_packages()`` to support working with packages that are either
933 in the filesystem or zip files.
934
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000935- The mailbox module can now modify and delete messages from
936 mailboxes, in addition to simply reading them. Thanks to Gregory
937 K. Johnson for writing the code, and to the 2005 Google Summer of
938 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000939
Tim Petersc7605f22006-04-17 21:12:33 +0000940- The ``__del__`` method of class ``local`` in module ``_threading_local``
941 returned before accomplishing any of its intended cleanup.

Anthony Baxtere29002c2006-04-12 12:07:31 +0000949- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
950 Windows. Bug #1469163.
951
Phillip J. Eby47032112006-04-11 01:07:43 +0000952- The warnings, linecache, inspect, traceback, site, and doctest modules
953 were updated to work correctly with modules imported from zipfiles or
954 via other PEP 302 __loader__ objects.

960
Neal Norwitza31bf182006-04-09 03:35:43 +0000961- Fix exception when doing glob.glob('anything*/')
962
Skip Montanaro262fb922006-04-21 02:31:07 +0000963- The pstats.Stats class accepts an optional stream keyword argument to
964 direct output to an alternate file-like object.
965
Anthony Baxter51bcb682006-04-05 14:51:42 +0000966Build
967-----
968
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000969- The Makefile now has a reindent target, which runs reindent.py on
970 the library.
971
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000972- Patch #1470875: Building Python with MS Free Compiler
973
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000974- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000975
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000976- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
977 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000978 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000979 CXX from --with-cxx-main, see description in README.
980
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000981- Patch #1429775: Link extension modules with the shared libpython.
982
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000983- Fixed a libffi build problem on MIPS systems.
984
Tim Peters8931ff12006-05-13 23:28:20 +0000985- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
986 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
987 and "%zu" for unsigned integers of type ``size_t``.
988
Anthony Baxter51bcb682006-04-05 14:51:42 +0000989Tests
990-----
991
Nick Coghlanda2268f2006-04-24 04:37:15 +0000992- test_contextlib now checks contextlib.nested can cope with exceptions
993 being raised and caught inside exit handlers.
994
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000995- test_cmd_line now checks operation of the -m and -c command switches
996
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000997- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
998 it separately and by hand. It also wasn't cleaning up its changes to
999 the current Decimal context.
1000
Thomas Woutersabd08882006-04-26 15:53:30 +00001001- regrtest.py now has a -M option to run tests that test the new limits of
1002 containers, on 64-bit architectures. Running these tests is only sensible
1003 on 64-bit machines with more than two gigabytes of memory. The argument
1004 passed is the maximum amount of memory for the tests to use.

1013-------------
1014
Tim Petersb06d28c2006-05-12 01:57:59 +00001015- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1016
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001017- PEP 343: Added Context Types section to the library reference
1018 and attempted to bring other PEP 343 related documentation into
1019 line with the implementation and/or python-dev discussions.
1020
Tim Peters8dc73d22006-04-24 02:03:16 +00001021- Bug #1337990: clarified that ``doctest`` does not support examples
1022 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001025What's New in Python 2.5 alpha 1?
1026=================================
1027
Anthony Baxterebed3f62006-04-03 15:03:44 +00001028*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001029
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001030Core and builtins
1031-----------------
1032
Nick Coghlan43832302006-04-23 17:04:07 +00001033- PEP 338: -m command line switch now delegates to runpy.run_module
1034 allowing it to support modules in packages and zipfiles
1035
Martin v. Löwisc661b882006-04-20 04:54:23 +00001036- On Windows, .DLL is not an accepted file name extension for
1037 extension modules anymore; extensions are only found if they
1038 end in .PYD.
1039
Martin v. Löwisea62d252006-04-03 10:56:49 +00001040- Bug #1421664: sys.stderr.encoding is now set to the same value as
1041 sys.stdout.encoding.
1042
Neal Norwitz92e212f2006-04-03 04:48:37 +00001043- __import__ accepts keyword arguments.
1044
Georg Brandlccadf842006-03-31 18:54:53 +00001045- Patch #1460496: round() now accepts keyword arguments.
1046
Anthony Baxter262c00a2006-03-30 10:53:17 +00001047- Fixed bug #1459029 - unicode reprs were double-escaped.
1048
Hye-Shik Changd478f342006-03-23 12:32:36 +00001049- Patch #1396919: The system scope threads are reenabled on FreeBSD
1050 5.4 and later versions.
1051
Neal Norwitze98ccf62006-03-23 05:39:47 +00001052- Bug #1115379: Compiling a Unicode string with an encoding declaration
1053 now gives a SyntaxError.
1054
Georg Brandlabd1ff82006-03-18 07:59:59 +00001055- Previously, Python code had no easy way to access the contents of a
1056 cell object. Now, a ``cell_contents`` attribute has been added
1057 (closes patch #1170323).
1058
Tim Peterscf79aac2006-03-16 01:14:46 +00001059- Patch #1123430: Python's small-object allocator now returns an arena to
1060 the system ``free()`` when all memory within an arena becomes unused
1061 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1062 freed. Some applications will see a drop in virtual memory size now,
1063 especially long-running applications that, from time to time, temporarily
1064 use a large number of small objects. Note that when Python returns an
1065 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001066 platform C library will in turn return that memory to the operating system.
1067 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001068 appears to be effective at least on Microsoft C and gcc-based systems.
1069 Thanks to Evan Jones for hard work and patience.
1070
Georg Brandl533ff6f2006-03-08 18:09:27 +00001071- Patch #1434038: property() now uses the getter's docstring if there is
1072 no "doc" argument given. This makes it possible to legitimately use
1073 property() as a decorator to produce a read-only property.
1074
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001075- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1076 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1077 of requiring an int or long in slicing and a few other contexts, enabling
1078 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1079
Neal Norwitz995acdf2006-03-07 05:01:00 +00001080- Fixed various bugs reported by Coverity's Prevent tool.
1081
Brett Cannonbf364092006-03-01 04:25:17 +00001082- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1083 new exception base class, BaseException, which has a new message attribute.
1084 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1085 Raising a string exception now raises a DeprecationWarning.
1086
Thomas Woutersfb609f42006-02-28 16:37:25 +00001087- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1088 explicitly relative, using 'from .module import name' to mean 'from the same
1089 package as this module is in. Imports without dots still default to the
1090 old relative-then-absolute, unless 'from __future__ import
1091 absolute_import' is used.
1092
Brett Cannona7446e32006-02-27 23:39:10 +00001093- Properly check if 'warnings' raises an exception (usually when a filter set
1094 to "error" is triggered) when raising a warning for raising string
1095 exceptions.
1096
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001097- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001098 The name was removed from Include/code.h.
1099
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001100- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001101
Guido van Rossum1968ad32006-02-25 22:38:04 +00001102- Patch 1433928:
1103 - The copy module now "copies" function objects (as atomic objects).
1104 - dict.__getitem__ now looks for a __missing__ hook before raising
1105 KeyError.
1106
Tim Peters84ef21c2006-02-28 20:39:06 +00001107- PEP 343: with statement implemented. Needs ``from __future__ import
1108 with_statement``. Use of 'with' as a variable will generate a warning.
1109 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001110 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001111 The following objects have __context__ methods:
1112 - The built-in file type.
1113 - The thread.LockType type.
1114 - The following types defined by the threading module:
1115 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1116 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001117
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001118- Fix the encodings package codec search function to only search
1119 inside its own package. Fixes problem reported in patch #1433198.
1120
1121 Note: Codec packages should implement and register their own
1122 codec search function. PEP 100 has the details.
1123
Tim Peters9ea89d22006-06-04 03:26:02 +00001124- PEP 353: Using ``Py_ssize_t`` as the index type.
1125
1126- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1127 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1128 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1129 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1130 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001131
Neal Norwitzfc76d632006-01-10 06:03:13 +00001132- Patch #1400181, fix unicode string formatting to not use the locale.
1133 This is how string objects work. u'%f' could use , instead of .
1134 for the decimal point. Now both strings and unicode always use periods.
1135
Neal Norwitz671b9e32006-01-09 07:07:12 +00001136- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1137 configure would break checking curses.h.
1138
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001139- Bug #959576: The pwd module is now builtin. This allows Python to be
1140 built on UNIX platforms without $HOME set.
1141
Neal Norwitzc10978f2005-12-19 06:07:16 +00001142- Bug #1072182, fix some potential problems if characters are signed.
1143
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001144- Bug #889500, fix line number on SyntaxWarning for global declarations.
1145
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001146- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1147
Neal Norwitze7214a12005-12-18 05:03:17 +00001148- Support for converting hex strings to floats no longer works.
1149 This was not portable. float('0x3') now raises a ValueError.
1150
Barry Warsaw2a38a862005-12-18 01:27:35 +00001151- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001152 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001153 is now displayed in interactive prompt banner.
1154
Georg Brandlfa166682005-12-17 21:45:17 +00001155- Implementation of PEP 341 - Unification of try/except and try/finally.
1156 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001157 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001158
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001159- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1160 now encodes backslash correctly.
1161
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001162- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1163
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001164- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001165 and long longs.
1166
Neal Norwitz67715f02005-11-09 06:59:35 +00001167- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001168 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001169 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001170
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001171- Replaced most Unicode charmap codecs with new ones using the
1172 new Unicode translate string feature in the builtin charmap
1173 codec; the codecs were created from the mapping tables available
1174 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1175 encodings now include a mapping for the Apple logo)
1176
Tim Peterse3547fd2005-12-16 23:13:57 +00001177- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001178
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001179- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001180
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001181- A new AST parser implementation was completed. The abstract
1182 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001183 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001184
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001185- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001186 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1187
Neal Norwitz708e51a2005-10-03 04:48:15 +00001188- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1189
Neal Norwitz11bd1192005-10-03 00:54:56 +00001190- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1191 Provide a warning when a directory is passed on the command line.
1192
Neal Norwitz40d37812005-10-02 01:48:49 +00001193- Fix segfault with invalid coding.
1194
1195- SF bug #772896: unknown encoding results in MemoryError.
1196
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001197- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001198 supported a __len__() method which evaluated to False when the iterator
1199 was empty.
1200
Guido van Rossum630db602005-09-20 18:49:54 +00001201- On 64-bit platforms, when __len__() returns a value that cannot be
1202 represented as a C int, raise OverflowError.
1203
Skip Montanarof8948ca2005-09-19 03:54:46 +00001204- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001205 present).

Georg Brandl80bbf3f2005-09-14 19:38:29 +00001207- SF bug #893549: parsing keyword arguments was broken with a few format
1208 codes.
1209
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001210- Changes donated by Elemental Security to make it work on AIX 5.3
1211 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1212 bug #105470: test_pwd fails on 64bit system (Opteron).
1213
Guido van Rossum539c6622005-09-14 17:49:54 +00001214- Changes donated by Elemental Security to make it work on HP-UX 11 on
1215 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1216
Georg Brandl4550b8d2005-08-26 06:43:52 +00001217- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001218 (fixes bug #1119418).
1219
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001220- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1221
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001222- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1223 exceptions that cause a function to exit.
1224
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001225- The implementation of set() and frozenset() was revised to use its
1226 own internal data structure. Memory consumption is reduced by 1/3
1227 and there are modest speed-ups as well. The API is unchanged.
1228
Tim Petersde7990b2005-07-17 23:45:23 +00001229- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1230
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001231- SF bug #1229429: PyObject_CallMethod failed to decrement some
1232 reference counts in some error exit cases.
1233
Tim Petersecc6e6a2005-07-10 22:30:55 +00001234- SF bug #1185883: Python's small-object memory allocator took over
1235 a block managed by the platform C library whenever a realloc specified
1236 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001237 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001238 portable way to copy data from the C-managed block into Python's
1239 small-object space without risking a memory fault. Python's small-object
1240 realloc now leaves such blocks under the control of the platform C
1241 realloc.
1242
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001243- SF bug #1232517: An overflow error was not detected properly when
1244 attempting to convert a large float to an int in os.utime().
1245
Raymond Hettinger3296e692005-06-29 23:29:56 +00001246- SF bug #1224347: hex longs now print with lowercase letters just
1247 like their int counterparts.
1248
Michael W. Hudson188d4362005-06-20 16:52:57 +00001249- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1250 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1251 interpreter states; back out that fix and do a better job (see
1252 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1253 for a longer write-up of the problem).
1254
Michael W. Hudsondf888462005-06-03 14:41:55 +00001255- SF patch #1180995: marshal now uses a binary format by default when
1256 serializing floats.
1257
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001258- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1259 the routines that promise to produce IEEE 754 binary representations
1260 of floats now simply copy bytes around.
1261
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001262- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1263 278.
1264
Brett Cannonc3647ac2005-04-26 03:45:26 +00001265- patch #1109424: int, long, float, complex, and unicode now check for the
1266 proper magic slot for type conversions when subclassed. Previously the
1267 magic slot was ignored during conversion. Semantics now match the way
1268 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001269 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001270 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001271 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001272
Barry Warsawc8d907c2005-04-19 23:43:40 +00001273- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1274 NULL, now raise an AttributeError when attempting to set or delete the
1275 attribute. Previously a TypeError was raised, but this was inconsistent
1276 with the equivalent pure-Python implementation.
1277
Michael W. Hudson774479c2005-04-18 08:46:17 +00001278- It is now safe to call PyGILState_Release() before
1279 PyEval_InitThreads() (note that if there is reason to believe there
1280 are multiple threads around you still must call PyEval_InitThreads()
1281 before using the Python API; this fix is for extension modules that
1282 have no way of knowing if Python is multi-threaded yet).
1283
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001284- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1285 disabled caused a crash.
1286
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001287- Bug #1165306: instancemethod_new allowed the creation of a method
1288 with im_class == im_self == NULL, which caused a crash when called.
1289
Tim Petersecc6e6a2005-07-10 22:30:55 +00001290- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001291 fixes the crash seen in bug #1165761
1292
Raymond Hettinger96229b12005-03-11 06:49:40 +00001293- Added two new builtins, any() and all().
1294
Brett Cannon409d8f22005-03-05 06:47:57 +00001295- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001296 (e.g., ``class C(): pass`` is no longer a syntax error).
1297 Patch #1176012 added support to the 'parser' module and 'compiler' package
1298 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001299
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001300- Patch #1115086: Support PY_LONGLONG in structmember.
1301
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001302- Bug #1155938: new style classes did not check that __init__() was
1303 returning None.
1304
Tim Petersecc6e6a2005-07-10 22:30:55 +00001305- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001306 ('\') with a specific error message.
1307
Martin v. Löwisff232d72005-03-03 09:24:38 +00001308- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1309
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001310- Bug #1124295: the __name__ attribute of file objects was
1311 inadvertently made inaccessible in restricted mode.
1312
Tim Petersecc6e6a2005-07-10 22:30:55 +00001313- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001314 an ferror() call.
1315
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001316- min() and max() now support key= arguments with the same meaning as in
1317 list.sort().
1318
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001319- The peephole optimizer now performs simple constant folding in expressions:
1320 (2+3) --> (5).
1321
Raymond Hettingera422c342005-01-11 03:03:27 +00001322- set and frozenset objects can now be marshalled. SF #1098985.
1323
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001324- Bug #1077106: Poor argument checking could cause memory corruption
1325 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001326
Jeremy Hyltonab630502005-02-04 18:44:06 +00001327- The parser did not complain about future statements in illegal
1328 positions. It once again reports a syntax error if a future
1329 statement occurs after anything other than a doc string.
1330
Neil Schemenauercf52c072005-08-12 17:34:58 +00001331- Change the %s format specifier for str objects so that it returns a
1332 unicode instance if the argument is not an instance of basestring and
1333 calling __str__ on the argument returns a unicode instance.
1334
Tim Petersf4e69282006-02-27 17:15:31 +00001335- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1336 current thread state when the auto-GIL-state machinery knows about
1337 it (since the thread state is being deleted, continuing to remember it
1338 can't help, but can hurt if another thread happens to get created with
1339 the same thread id).
1340
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001341Extension Modules
1342-----------------
1343

1358
1359- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1360
1361- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001362 is deprecated. The undocumented re.engine variable no longer exists.
1363

1365 SS2 (single-shift 2) escape sequences correctly.
1366
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001367- The unicodedata module was updated to the 4.1 version of the Unicode
1368 database. The 3.2 version is still available as unicodedata.db_3_2_0
1369 for applications that require this specific version (such as IDNA).
1370
Neal Norwitzb62c4332006-03-04 18:35:47 +00001371- The timing module is no longer built by default. It was deprecated
1372 in PEP 4 in Python 2.0 or earlier.
1373
Guido van Rossum1968ad32006-02-25 22:38:04 +00001374- Patch 1433928: Added a new type, defaultdict, to the collections module.
1375 This uses the new __missing__ hook behavior added to dict (see above).
1376
Georg Brandldbd83392006-02-20 09:42:33 +00001377- Bug #854823: socketmodule now builds on Sun platforms even when

1379
Georg Brandlf4f44152006-02-18 22:29:33 +00001380- Patch #1393157: os.startfile() now has an optional argument to specify
1381 a "command verb" to invoke on the file.
1382
Neal Norwitz082b2df2006-02-07 07:04:46 +00001383- Bug #876637, prevent stack corruption when socket descriptor

1391 than the system default domain.
1392
Martin v. Löwis14694662006-02-03 12:54:16 +00001393- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1394 are reported, the limit on path name lengths is removed, and stat reports
1395 WindowsError now (instead of OSError).
1396
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001397- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001471- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1472 the request code argument, which results in more C-like behaviour
1473 for large or negative values.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001531- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1532 been renamed to have only a single underscore prefix. This was done to
1533 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001534
Nick Coghlan43832302006-04-23 17:04:07 +00001535- PEP 338: new module runpy defines a run_module function to support
1536 executing modules which provide access to source code or a code object
1537 via the PEP 302 import mechanisms.
1538
Anthony Baxter93f5b932006-04-03 08:05:07 +00001539- The email module's parsedate_tz function now sets the daylight savings

1547 in attribute values.
1548
Anthony Baxterc51ee692006-04-01 00:57:31 +00001549- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001550 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001551 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001552 module will not be built.
1553
Tim Petersc17976e2006-04-01 00:26:53 +00001554- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1555 aren't officially supported here, and trying to use them will probably
1556 raise an exception some day. But dicts have been allowed, and "mostly
1557 worked", so support for them won't go away without warning.
1558
Georg Brandl338ef7d2006-03-31 18:42:16 +00001559- Bug #1445068: getpass.getpass() can now be given an explicit stream
1560 argument to specify where to write the prompt.
1561

1571 to make it easier to monitor when daemon threads have completed
1572 processing all enqueued tasks. Patch #1455676.
1573

1577
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001578- email 4.0 package now integrated. This is largely the same as the email 3.0
1579 package that was included in Python 2.3, except that PEP 8 module names are
1580 now used (e.g. mail.message instead of email.Message). The MIME classes
1581 have been moved to a subpackage (e.g. email.mime.text instead of
1582 email.MIMEText). The old names are still supported for now. Several
1583 deprecated Message methods have been removed and lots of bugs have been
1584 fixed. More details can be found in the email package documentation.
1585
Walter Dörwald40108c92006-03-27 08:15:44 +00001586- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1587 (a subclass of tuple) that provides incremental decoders and encoders
1588 (a way to use stateful codecs without the stream API). Python functions
1589 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1590 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1591 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001592
Walter Dörwald067db482006-03-15 22:17:27 +00001593- Patch #1359365: Calling next() on a closed StringIO.String object raises
1594 a ValueError instead of a StopIteration now (like file and cString.String do).
1595 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1596 called before (like file and StringIO.StringIO do).

Martin v. Löwis3e865952006-01-24 15:51:21 +00001646 specifications, raises IOErrors when proxies for unsupported protocols
1647 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001670 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1671 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1672 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1673 Ronald L. Rivest offered this advice for Python:
1674
1675 "The consensus of researchers in this area (at least as
1676 expressed at the NIST Hash Function Workshop 10/31/05),
1677 is that SHA-256 is a good choice for the time being, but
1678 that research should continue, and other alternatives may
1679 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001680
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001681- Added a subset of Fredrik Lundh's ElementTree package. Available

1756
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001757- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1758 to W3C name (404 -> 'Not Found'). RFE #1216944.
1759
Georg Brandl9e43acf2005-07-04 17:16:07 +00001760- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1761 as this can cause problems with apps closing all file descriptors.
1762
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001763- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001764 it can be missing in embedded interpreters

1774 Bug #1224621.
1775
Raymond Hettinger68c04532005-06-10 11:05:19 +00001776- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001777 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001778 the generate_tokens() function now accepts a callable argument that
1779 terminates by raising StopIteration.
1780
Georg Brandl9166e1a2005-06-04 09:20:03 +00001781- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1789 class at all.
1790
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001791- distutils.commands.upload was added to support uploading distribution

1795 them to PyPI.
1796
Raymond Hettinger267b8682005-03-27 10:47:39 +00001797- decimal operator and comparison methods now return NotImplemented
1798 instead of raising a TypeError when interacting with other types. This
1799 allows other classes to implement __radd__ style methods and have them
1800 work as expected.
1801
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001802- Bug #1163325: Decimal infinities failed to hash. Attempting to
1803 hash a NaN raised an InvalidOperation instead of a TypeError.
1804
Tim Petersecc6e6a2005-07-10 22:30:55 +00001805- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1839
Guido van Rossumd0641422005-02-03 15:01:24 +00001840- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1841 disables recursive traversal through instance attributes, which can
1842 be exploited in various ways.
1843
Tim Peterse3547fd2005-12-16 23:13:57 +00001844- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001845 flags on the HTTP listening socket.
1846
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001847- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1848 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1849
Fred Drakefbdeaad2006-07-29 16:56:15 +00001850- Patches #893642, #1039083: add allow_none, encoding arguments to
1851 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001852
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001853- Bug #1110478: Revert os.environ.update to do putenv again.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001855- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1856
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001857- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1858
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001859- Enhancements to the csv module:
1860
1861 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001862 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001863 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001864 + Dialect parameter parsing has been re-implemented to improve error
1865 reporting.
1866 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1867 dictates.
1868 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001869 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001870 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001871 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1872 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001873 + reader now allows \r characters to be quoted (previously it only allowed
1874 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001875 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001876 + Dialect classes passed to the module are no longer instantiated by
1877 the module before being parsed (the former validation scheme required
1878 this, but the mechanism was unreliable).
1879 + The dialect registry now contains instances of the internal
1880 C-coded dialect type, rather than references to python objects.
1881 + the internal c-coded dialect type is now immutable.
1882 + register_dialect now accepts the same keyword dialect specifications
1883 as the reader and writer, allowing the user to register dialects
1884 without first creating a dialect class.
1885 + a configurable limit to the size of parsed fields has been added -
1886 previously, an unmatched quote character could result in the entire
1887 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001888 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001889 the parser field size limit (returning the former limit). The initial
1890 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001891 + A line_num attribute has been added to the reader object, which tracks
1892 the number of lines read from the source iterator. This is not
1893 the same as the number of records returned, as records can span
1894 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001895 + reader and writer objects were not being registered with the cyclic-GC.
1896 This has been fixed.
1897
Brett Cannone6539c42005-01-08 02:43:53 +00001898- _DummyThread objects in the threading module now delete self.__block that is
1899 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1900 lock primitives tend to be limited in number and thus should not be wasted on
1901 a _DummyThread object. Fixes bug #1089632.
1902
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001903- The imghdr module now detects Exif files.
1904
Raymond Hettinger6065d322004-12-20 23:51:53 +00001905- StringIO.truncate() now correctly adjusts the size attribute.
1906 (Bug #951915).
1907
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001908- locale.py now uses an updated locale alias table (built using
1909 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1910 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001911 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001912
Raymond Hettinger3557f422004-12-07 12:02:02 +00001913- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1914
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001915- the pickle module no longer accepts the deprecated None option in the
1916 args tuple returned by __reduce__().
1917
Brett Cannon84667c02004-12-07 03:25:18 +00001918- optparse now optionally imports gettext. This allows its use in setup.py.
1919
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001920- the pickle module no longer uses the deprecated bin parameter.
1921
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001922- the shelve module no longer uses the deprecated binary parameter.
1923
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001924- the pstats module no longer uses the deprecated ignore() method.
1925
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001926- the filecmp module no longer uses the deprecated use_statcache argument.
1927
Raymond Hettinger664347b2004-12-04 21:21:53 +00001928- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1929 extended or overridden by subclasses. Formerly, the subclassed method would
1930 be ignored by the rest of the module. (Bug #1078905).
1931
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001932- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001933 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001934
Walter Dörwald36733692004-12-22 12:50:50 +00001935- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1936 once when a size argument is given. This prevents a buffer overflow in the
1937 tokenizer with very long source lines.
1938
Barry Warsaw538561e2006-01-01 21:48:54 +00001939- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1940 immediately after creating the object, without any intervening
1941 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001942
Skip Montanaro05885812005-01-16 20:48:27 +00001943- The reconvert.quote function can now emit triple-quoted strings. The
1944 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001945
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001946- ``UserString.MutableString`` now supports negative indices in
1947 ``__setitem__`` and ``__delitem__``
1948
Greg Ward40407942005-03-05 02:53:17 +00001949- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1950 correctly.
1951
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001952- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1953 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1954 character even if the user has passed a size parameter to get a proper
1955 line ending. Remove the special handling of a "\r\n" that has been split
1956 between two lines.
1957
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001958- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1959 about illegal code points. The codec now supports PEP 293 style error
1960 handlers.
1961
Walter Dörwald78a78b02005-09-01 12:04:29 +00001962- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001963 from the input stream, so that the output is a byte string in the correct
1964 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001965
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001966- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1967 considering it exactly like a '*'.
1968
Walter Dörwald007f8df2005-10-09 19:42:27 +00001969- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1970 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001971
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001972- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1973
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001974- Patch #1413711: Certain patterns of differences were making difflib
1975 touch the recursion limit.
1976
Walter Dörwald58917a62006-03-31 15:26:22 +00001977- Bug #947906: An object oriented interface has been added to the calendar
1978 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001979 called as a script (e.g. via ``python -mcalendar``). Localized month and
1980 weekday names can be ouput (even if an exotic encoding is used) using
1981 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001982

Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001995- Patch #881820: look for openpty and forkpty also in libbsd.
1996
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001997- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1998 The zlib module is now builtin on Windows.
1999
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002000- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2001
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002002- Bug #1189330: configure did not correctly determine the necessary
2003 value of LINKCC if python was built with GCC 4.0.
2004
Trent Mick8321b422005-07-26 02:29:21 +00002005- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2006 vulnerability in zlib 1.2.1 and 1.2.2.
2007
Brett Cannon08cd5982005-04-24 22:26:38 +00002008- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2009 flags that change binary compatibility. Changes were also made to
2010 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002011 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002012
Bob Ippolitoed233462005-03-29 13:47:59 +00002013- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2014 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2015 no longer exists). This configure patch makes things right.
2016
Martin v. Löwise2713be2005-03-08 15:03:08 +00002017- Bug #1158607: Build with --disable-unicode again.
2018
Brett Cannon46d96232005-02-16 00:07:19 +00002019- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2020 defined. Discovered as a result of not being able to build on OS X.
2021
Brett Cannon516592f2004-12-07 00:42:59 +00002022- setup.py now uses the directories specified in LDFLAGS using the -L option
2023 and in CPPFLAGS using the -I option for adding library and include
2024 directories, respectively, for compiling extension modules against. This has
2025 led to the core being compiled using the values in CPPFLAGS. It also removes
2026 the need for the special-casing of both DarwinPorts and Fink for darwin since
2027 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2028 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2029 Fink, ``-I/opt/local/include`` for DarwinPorts).
2030
Brett Cannon43802422005-02-10 20:48:03 +00002031- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2032 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2033 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2034 Closes bug #1096244. Thanks Gregory Bond.

2037-----
2038
Tim Petersc9d78aa2006-03-26 23:27:58 +00002039- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2040 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2041 is obtained via the ``PyObject_`` family, it must be released via the
2042 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2043 always been officially true, but when Python's small-object allocator was
2044 introduced, an attempt was made to cater to a few extension modules
2045 discovered at the time that obtained memory via ``PyObject_New`` but
2046 released it via ``PyMem_DEL``. It's years later, and if such code still
2047 exists it will fail now (probably with segfaults, but calling wrong
2048 low-level memory management functions can yield many symptoms).
2049
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002050- Added a C API for set and frozenset objects.
2051

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002054- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2055 mapping argument now. This string is used as a mapping table. Byte values
2056 greater than the length of the string and 0xFFFE are treated as undefined
2057 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002065- Patch #1276356: New resource "urlfetch" is implemented. This enables
2066 even impatient people to run tests that require remote files.
