Fred Drake53912162006-07-29 13:22:49 +000039What's New in Python 2.5 beta 3?
40================================
Neal Norwitza1f10902006-07-12 07:28:29 +000041
Anthony Baxter5d32a9f2006-08-02 07:43:09 +000042*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +000043
44Core and builtins
45-----------------
46
Neal Norwitzc5e060d2006-08-02 06:14:22 +000047- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
48 returned a long (see PEP 353).
49
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000050- Bug #1515471: string.replace() accepts character buffers again.
51
Neal Norwitz07aadb12006-07-30 06:55:48 +000052- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
53 This provides the proper warning for struct.pack().
54 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
55
Neal Norwitz0d62a062006-07-30 06:53:31 +000056- Patch #1531113: Fix augmented assignment with yield expressions.
57 Also fix a SystemError when trying to assign to yield expressions.
58
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000059- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
60 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
61 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
62 excessive filesystem operations during imports.
63
Tim Petersbc24eee2006-07-27 01:14:53 +000064- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
65 operations on signed longs that are formally undefined by C.
66 Unfortunately, at least one compiler now cares about that, so complicated
67 the code to make that compiler happy again.
68
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000069- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
70
Martin v. Löwisd22968a2006-07-24 11:54:53 +000071- Patch #1232023: Stop including current directory in search
72 path on Windows.
73
Neal Norwitze1fdb322006-07-21 05:32:28 +000074- Fix some potential crashes found with failmalloc.
75
Neal Norwitze7563102006-07-17 01:00:16 +000076- Fix warnings reported by Klocwork's static analysis tool.
77
Neal Norwitz84be93b2006-07-16 01:50:38 +000078- Bug #1512814, Fix incorrect lineno's when code within a function
79 had more than 255 blank lines.
80
Georg Brandl9dceedb2006-07-12 15:31:17 +000081- Patch #1521179: Python now accepts the standard options ``--help`` and
82 ``--version`` as well as ``/?`` on Windows.
83
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000084- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000085 again. Fixing this problem required changing the .pyc magic number.
86 This means that .pyc files generated before 2.5c1 will be regenerated.
87
Tim Peters112aad32006-07-19 00:03:19 +000088- Bug #1524317: Compiling Python ``--without-threads`` failed.
89 The Python core compiles again then, and, in a build without threads, the
90 new ``sys._current_frames()`` returns a dictionary with one entry,
91 mapping the faux "thread id" 0 to the current frame.
92
Ronald Oussoren3075e162006-07-25 20:28:55 +000093- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000094
Ronald Oussoren3075e162006-07-25 20:28:55 +000095
Neal Norwitza1f10902006-07-12 07:28:29 +000096Library
97-------
98
Martin v. Löwis961b91b2006-08-02 13:53:55 +000099- Correction of patch #1455898: In the mbcs decoder, set final=False
100 for stream decoder, but final=True for the decode function.
101
Georg Brandl07fec3a2006-08-01 18:49:24 +0000102- os.urandom no longer masks unrelated exceptions like SystemExit or
103 KeyboardInterrupt.
104
Martin v. Löwis4e678382006-07-30 13:00:31 +0000105- Bug #1525866: Don't copy directory stat times in
106 shutil.copytree on Windows
107
Georg Brandle34ac7c2006-07-30 11:07:23 +0000108- Bug #1002398: The documentation for os.path.sameopenfile now correctly
109 refers to file descriptors, not file objects.
110
Fred Drakefbdeaad2006-07-29 16:56:15 +0000111- Rename of the xml package to xmlcore, and the import hackery done to
112 make it appear at both names, has been removed. Bug #1511497,
113 #1513611, and probably others.
114
Georg Brandledd9b0d2006-07-29 09:33:26 +0000115- Bug #1441397: The compiler module now recognizes module and function
116 docstrings correctly as it did in Python 2.4.
117
Tim Peters6f681472006-07-27 23:44:37 +0000118- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
119 lost that tests are sorted by name before being run. This rarely
120 matters for well-written tests, but can create baffling symptoms if
121 side effects from one test to the next affect outcomes. ``DocTestFinder``
122 has been changed to sort the list of tests it returns.
123
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000124- The distutils version has been changed to 2.5.0, and are now kept
125 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000126
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000127- Bug #978833: Really close underlying socket in _socketobject.close.
128
Georg Brandl0619a322006-07-26 07:40:17 +0000129- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
130 with title().
131
Georg Brandlcf0c1722006-07-26 07:23:32 +0000132- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
133 to recursive calls and call it with the failing package name.
134
Martin v. Löwis0b483032006-07-25 09:53:12 +0000135- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
136
Georg Brandlc13c34c2006-07-24 14:09:56 +0000137- Patch #1515343: Fix printing of deprecated string exceptions with a
138 value in the traceback module.
139
Greg Ward48fae7a2006-07-23 16:05:51 +0000140- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
141
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000142- Patch #1524429: Use repr() instead of backticks in Tkinter again.
143
Brett Cannoncaebe222006-07-18 04:41:36 +0000144- Bug #1520914: Change time.strftime() to accept a zero for any position in its
145 argument tuple. For arguments where zero is illegal, the value is forced to
146 the minimum value that is correct. This is to support an undocumented but
147 common way people used to fill in inconsequential information in the time
148 tuple pre-2.4.
149
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000150- Patch #1220874: Update the binhex module for Mach-O.
151
Barry Warsawb110bad2006-07-21 14:51:07 +0000152- The email package has improved RFC 2231 support, specifically for
153 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
154 (name*0=<blah>) parameter continuations. This may change the types of
155 values returned from email.message.Message.get_param() and friends.
156 Specifically in some cases where non-encoded continuations were used,
157 get_param() used to return a 3-tuple of (None, None, string) whereas now it
158 will just return the string (since non-encoded continuations don't have
159 charset and language parts).
160
161 Also, whereas % values were decoded in all parameter continuations, they are
162 now only decoded in encoded parameter parts.
163
Ronald Oussoren3075e162006-07-25 20:28:55 +0000164- Bug #1517990: IDLE keybindings on MacOS X now work correctly
165
166- Bug #1517996: IDLE now longer shows the default Tk menu when a
167 path browser, class browser or debugger is the frontmost window on MacOS X
168
Barry Warsaw00decd72006-07-27 23:43:15 +0000169- Patch #1520294: Support for getset and member descriptors in types.py,
170 inspect.py, and pydoc.py. Specifically, this allows for querying the type
171 of an object against these built-in types and more importantly, for getting
172 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +0000175Extension Modules
176-----------------
177
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000178- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
179 a socket operation on a socket with a timeout, the exception will be
180 caught correctly. Previously, the exception was not caught.
181
Thomas Heller1393d6a2006-07-28 21:43:20 +0000182- Patch #1529514: The _ctypes extension is now compiled on more
183 openbsd target platforms.
184
Tim Peters9cab5932006-07-28 00:30:00 +0000185- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
186 a memory leak, affecting pickles and deep copies.
187
Tim Petersbc24eee2006-07-27 01:14:53 +0000188- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000189 Paul Eggert.
190
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000191- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
192
Thomas Hellerce049a02006-07-14 17:51:14 +0000193- Patch #1521817: Index range checking on ctypes arrays containing
194 exactly one element enabled again. This allows iterating over these
195 arrays, without the need to check the array size before.
196
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000197- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000198 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000199 /dev/null in certain cases; this is now fixed.
200
Thomas Heller47d7a062006-07-12 08:43:47 +0000201- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
202 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000203
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000204- Because of a misspelled preprocessor symbol, ctypes was always
205 compiled without thread support; this is now fixed.
206
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000207- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
208 methods now allow their database parameter to be None as the
209 sleepycat API allows.
210
Matt Flemingec926502006-07-28 11:27:27 +0000211- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
212 bluetooth API compared with Linux and FreeBSD.
213
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000214Tests
215-----
216
217- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
218 how long the test file should take to play. Now accepts taking 2.93 secs
219 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
220
Georg Brandl4793aa32006-07-28 18:31:39 +0000221- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
222 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
223 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000224
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000225Build

Ronald Oussoren26cad082006-08-01 21:00:57 +0000230Mac
231---
232
233- PythonLauncher now works correctly when the path to the script contains
234 characters that are treated specially by the shell (such as quotes).
235
236- Bug #1527397: PythonLauncher now launches scripts with the working directory
237 set to the directory that contains the script instead of the user home
238 directory. That latter was an implementation accident and not what users
239 expect.

247Core and builtins
248-----------------
249
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000250- Bug #1441486: The literal representation of -(sys.maxint - 1)
251 again evaluates to a int object, not a long.
252
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000253- Bug #1501934: The scope of global variables that are locally assigned
254 using augmented assignment is now correctly determined.
255
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000256- Bug #927248: Recursive method-wrapper objects can now safely
257 be released.
258
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000259- Bug #1417699: Reject locale-specific decimal point in float()
260 and atof().
261
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000262- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
263 omit a default "error" argument for NULL pointer. This allows
264 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000265
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000266- Bug #1519018: 'as' is now validated properly in import statements.
267
Neal Norwitz28746ab2006-07-09 22:14:42 +0000268- On 64 bit systems, int literals that use less than 64 bits are
269 now ints rather than longs.
270
Neal Norwitzed657552006-07-10 00:04:44 +0000271- Bug #1512814, Fix incorrect lineno's when code at module scope
272 started after line 256.
273
Tim Peters32a83612006-07-10 21:08:24 +0000274- New function ``sys._current_frames()`` returns a dict mapping thread
275 id to topmost thread stack frame. This is for expert use, and is
276 especially useful for debugging application deadlocks. The functionality
277 was previously available in Fazal Majid's ``threadframe`` extension
278 module, but it wasn't possible to do this in a wholly threadsafe way from
279 an extension.

288
Tim Peters32a83612006-07-10 21:08:24 +0000289- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000290 environment variable to be set in order to the SDK environment
291 for finding the compiler, include files, etc.
292

296
Thomas Woutersadd19112006-07-05 11:03:49 +0000297- string.Template() now correctly handles tuple-values. Previously,
298 multi-value tuples would raise an exception and single-value tuples would
299 be treated as the value they contain, instead.
300
Martin v. Löwisede77f52006-07-03 13:01:35 +0000301- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

308 degrees and radians.
309
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000310- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000311 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000312
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000313- Bug #1514703: Only setup canvas window in turtle when the canvas
314 is created.
315
Martin v. Löwis7596e832006-07-01 15:33:37 +0000316- Bug #1513223: .close() of a _socketobj now releases the underlying
317 socket again, which then gets closed as it becomes unreferenced.
318
Fred Drake10497c82006-06-29 02:57:48 +0000319- Bug #1504333: Make sgmllib support angle brackets in quoted
320 attribute values.
321
322- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
323 sgmllib ('[' and ']' were not accepted).
324
Georg Brandl1be63af2006-06-28 20:23:25 +0000325- Fix a bug in the turtle module's end_fill function.
326
Brett Cannon53ab5b72006-06-22 16:49:14 +0000327- Bug #1510580: The 'warnings' module improperly required that a Warning
328 category be either a types.ClassType and a subclass of Warning. The proper
329 check is just that it is a subclass with Warning as the documentation states.
330
Georg Brandlad29e632006-06-21 17:45:17 +0000331- The compiler module now correctly compiles the new try-except-finally
332 statement (bug #1509132).
333
Neal Norwitz60373cd2006-06-22 06:30:50 +0000334- The wsgiref package is now installed properly on Unix.
335
Vinay Sajip28e57612006-07-01 10:45:20 +0000336- A bug was fixed in logging.config.fileConfig() which caused a crash on
337 shutdown when fileConfig() was called multiple times.
338
Gerhard Häring762fbd32006-07-02 17:48:30 +0000339- The sqlite3 module did cut off data from the SQLite database at the first
340 null character before sending it to a custom converter. This has been fixed
341 now.

344-----------------
345
Tim Peters112aad32006-07-19 00:03:19 +0000346- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
347 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
348 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000349
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000350- Assigning None to pointer type fields in ctypes structures possible
351 overwrote the wrong fields, this is fixed now.
352
353- Fixed a segfault in _ctypes when ctypes.wintypes were imported
354 on non-Windows platforms.
355
356- Bug #1518190: The ctypes.c_void_p constructor now accepts any
357 integer or long, without range checking.
358
359- Patch #1517790: It is now possible to use custom objects in the ctypes
360 foreign function argtypes sequence as long as they provide a from_param
361 method, no longer is it required that the object is a ctypes type.
362
363- The '_ctypes' extension module now works when Python is configured
364 with the --without-threads option.
365
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000366- Bug #1513646: os.access on Windows now correctly determines write
367 access, again.
368
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000369- Bug #1512695: cPickle.loads could crash if it was interrupted with
370 a KeyboardInterrupt.
371
Neal Norwitza12aa882006-07-06 06:45:08 +0000372- Bug #1296433: parsing XML with a non-default encoding and
373 a CharacterDataHandler could crash the interpreter in pyexpat.
374
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000375- Patch #1516912: improve Modules support for OpenVMS.

379
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000380- Automate Windows build process for the Win64 SSL module.
381
Tim Peters32a83612006-07-10 21:08:24 +0000382- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000383 Previously, the slight difference could cause compilation errors of the
384 'zlib' module on systems with more than one version of zlib.
385
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000386- The MSI compileall step was fixed to also support a TARGETDIR
387 with spaces in it.
388
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000389- Bug #1517388: sqlite3.dll is now installed on Windows independent
390 of Tcl/Tk.
391
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000392- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000393 trying to be installed even though it's empty.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000415
416Core and builtins
417-----------------
418
Georg Brandla56b9152006-06-19 06:35:54 +0000419- Patch #1507676: Error messages returned by invalid abstract object operations
420 (such as iterating over an integer) have been improved and now include the
421 type of the offending object to help with debugging.
422
Brett Cannonea3912b2006-06-13 21:46:41 +0000423- Bug #992017: A classic class that defined a __coerce__() method that returned
424 its arguments swapped would infinitely recurse and segfault the interpreter.
425
Neal Norwitz909eb122006-06-12 02:13:21 +0000426- Fix the socket tests so they can be run concurrently.
427
Neal Norwitzb9845e72006-06-12 02:11:18 +0000428- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000429 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000430
Brett Cannon22565aa2006-06-09 22:31:23 +0000431- Bug #532646: object.__call__() will continue looking for the __call__
432 attribute on objects until one without one is found. This leads to recursion
433 when you take a class and set its __call__ attribute to an instance of the
434 class. Originally fixed for classic classes, but this fix is for new-style.
435 Removes the infinite_rec_3 crasher.
436
Georg Brandl24250812006-06-09 18:45:48 +0000437- The string and unicode methods startswith() and endswith() now accept
438 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
439
Brett Cannonde3b0522006-06-08 17:00:45 +0000440- Buffer objects, at the C level, never used the char buffer
441 implementation even when the char buffer for the wrapped object was
442 explicitly requested (originally returned the read or write buffer).
443 Now a TypeError is raised if the char buffer is not present but is
444 requested.
445
Georg Brandlddbaa662006-06-04 21:56:52 +0000446- Patch #1346214: Statements like "if 0: suite" are now again optimized
447 away like they were in Python 2.4.
448
Georg Brandlb7c8f542006-05-27 12:30:25 +0000449- Builtin exceptions are now full-blown new-style classes instead of
450 instances pretending to be classes, which speeds up exception handling
451 by about 80% in comparison to 2.5a2.
452
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000453- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
454 Unicode 4.1.
455
Georg Brandlf4ef1162006-05-26 18:03:31 +0000456- Patch #921466: sys.path_importer_cache is now used to cache valid and
457 invalid file paths for the built-in import machinery which leads to
458 fewer open calls on startup.
459
Tim Peters696cf432006-05-24 21:10:40 +0000460- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
461 of-2 bases. The largest speedup is for inputs with about 1000 decimal
462 digits. Conversion from non-power-of-2 bases remains quadratic-time in
463 the number of input digits (it was and remains linear-time for bases
464 2, 4, 8, 16 and 32).
465
Tim Petersb713ec22006-05-23 18:45:30 +0000466- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
467 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
468 an integer close to ``sys.maxint``. This was repaired by patch
469 #1335972, which also gives a nice speedup.
470
Richard Jonescebbefc2006-05-23 18:28:17 +0000471- Patch #1337051: reduced size of frame objects.
472
473- PyErr_NewException now accepts a tuple of base classes as its
474 "base" parameter.
475
Richard Jones7c88dcc2006-05-23 10:37:38 +0000476- Patch #876206: function call speedup by retaining allocated frame
477 objects.
478
Georg Brandl7b90e162006-05-18 07:01:27 +0000479- Bug #1462152: file() now checks more thoroughly for invalid mode
480 strings and removes a possible "U" before passing the mode to the
481 C library function.
482
Neal Norwitz1004a532006-05-15 07:17:23 +0000483- Patch #1488312, Fix memory alignment problem on SPARC in unicode
484
Neal Norwitz373f0a72006-05-15 07:04:36 +0000485- Bug #1487966: Fix SystemError with conditional expression in assignment
486
Martin v. Löwis879768d2006-05-11 13:28:43 +0000487- WindowsError now has two error code attributes: errno, which carries
488 the error values from errno.h, and winerror, which carries the error
489 values from winerror.h. Previous versions put the winerror.h values
490 (from GetLastError()) into the errno attribute.
491
Martin v. Löwis77736712006-05-04 05:51:03 +0000492- Patch #1475845: Raise IndentationError for unexpected indent.
493
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000494- Patch #1479181: split open() and file() from being aliases for each other.
495
Tim Peters44bd9862006-06-01 13:49:23 +0000496- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
497 methods were always silently ignored by dictionaries when comparing keys.
498 They are now passed through (except when using the C API function
499 ``PyDict_GetItem()``, whose semantics did not change).
500
501- Bug #1456209: In some obscure cases it was possible for a class with a
502 custom ``__eq__()`` method to confuse dict internals when class instances
503 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
504 No, you don't have any code that did this ;-)

512
Brett Cannon6ee7d012006-06-08 16:23:04 +0000513- Change binascii.hexlify to accept a read-only buffer instead of only a char
514 buffer and actually follow its documentation.
515
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000516- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
517
Nick Coghlanc649ec52006-05-29 12:43:05 +0000518- Patch #1478788 (modified version): The functional extension module has
519 been renamed to _functools and a functools Python wrapper module added.
520 This provides a home for additional function related utilities that are
521 not specifically about functional programming. See PEP 309.
522
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000523- Patch #1493701: performance enhancements for struct module.
524
Georg Brandl378d5922006-05-17 14:26:50 +0000525- Patch #1490224: time.altzone is now set correctly on Cygwin.
526
Georg Brandl8d3342b2006-05-16 07:38:27 +0000527- Patch #1435422: zlib's compress and decompress objects now have a
528 copy() method.
529
Andrew MacIntyre92913322006-06-13 15:04:24 +0000530- Patch #1454481: thread stack size is now tunable at runtime for thread
531 enabled builds on Windows and systems with Posix threads support.
532
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000533- On Win32, os.listdir now supports arbitrarily-long Unicode path names
534 (up to the system limit of 32K characters).
535
536- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
537 As a result, these functions now raise WindowsError instead of OSError.
538
Tim Peters7a822da2006-05-25 21:50:17 +0000539- ``time.clock()`` on Win64 should use the high-performance Windows
540 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
541 Windows platforms).
542
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000543- Calling Tk_Init twice is refused if the first call failed as that
544 may deadlock.
545
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000546- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
547 accept it without potentially using an uninitialized pointer.
548
549- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
550 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
551 patch numbers 1494885 and 1494902]

Gregory P. Smith372b5832006-06-05 18:48:21 +0000553- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000554 [pybsddb project SF patch number 1466734]
555
Gregory P. Smith372b5832006-06-05 18:48:21 +0000556- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
557 parameter is supplied. [SF pybsddb bug #1477863]
558
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000559- bsddb: the __len__ method of a DB object has been fixed to return correct
560 results. It could previously incorrectly return 0 in some cases.
561 Fixes SF bug 1493322 (pybsddb bug 1184012).
562
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000563- bsddb: the bsddb.dbtables Modify method now raises the proper error and
564 aborts the db transaction safely when a modifier callback fails.
565 Fixes SF python patch/bug #1408584.
566
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000567- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000568 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000569 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
570 database calls that would previously deadlock. [SF python bug #775414]
571
Vinay Sajip28e57612006-07-01 10:45:20 +0000572- Patch #1446489: add support for the ZIP64 extensions to zipfile.

579
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000580- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
581 functions.
582

587
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000588- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
589
Martin v. Löwis337487e2006-06-17 09:15:14 +0000590- Patch #763580: Add name and value arguments to Tkinter variable
591 classes.
592
Georg Brandl83cc0d02006-06-14 08:50:03 +0000593- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
594 mime.types file for determining MIME types.
595
Georg Brandl2605ca82006-06-14 06:08:31 +0000596- Bug #1339007: Shelf objects now don't raise an exception in their
597 __del__ method when initialization failed.
598
Martin v. Löwisd8251432006-06-14 05:21:04 +0000599- Patch #1455898: The MBCS codec now supports the incremental mode for
600 double-byte encodings.
601
Tim Peters43898b42006-06-14 04:09:25 +0000602- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
603 guarantee that adjacent triples in the return list always describe
604 non-adjacent blocks. Previously, a pair of matching blocks could end
605 up being described by multiple adjacent triples that formed a partition
606 of the matching pair.
607
Greg Ward0e0c9f42006-06-11 16:24:11 +0000608- Bug #1498146: fix optparse to handle Unicode strings in option help,
609 description, and epilog.
610
Greg Wardd1c797e2006-06-11 14:42:41 +0000611- Bug #1366250: minor optparse documentation error.
612
Greg Ward7f547402006-06-11 00:40:49 +0000613- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
614 clarify docs.
615
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000616- The wsgiref package has been added to the standard library.
617
Nick Coghlan676725d2006-06-08 13:54:49 +0000618- The functions update_wrapper() and wraps() have been added to the functools
619 module. These make it easier to copy relevant metadata from the original
620 function when writing wrapper functions.
621
Tim Petersd6a9eef2006-06-05 01:48:21 +0000622- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
623 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000624
Martin v. Löwis3f767792006-06-04 19:36:28 +0000625- Patch #1359618: Speed up charmap encoder by using a trie structure
626 for lookup.
627
Tim Petersd609b1a2006-06-02 23:22:51 +0000628- The functions in the ``pprint`` module now sort dictionaries by key
629 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
630 if and only if its display required more than one line, although that
631 wasn't documented. The new behavior increases predictability; e.g.,
632 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
633
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000634- Patch #1497027: try HTTP digest auth before basic auth in urllib2
635 (thanks for J. J. Lee).
636
Georg Brandl2b330372006-05-28 20:23:12 +0000637- Patch #1496206: improve urllib2 handling of passwords with respect to
638 default HTTP and HTTPS ports.
639
George Yoshidaf3c65de2006-05-28 16:39:09 +0000640- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.

643
Georg Brandlb89316f2006-05-17 15:51:16 +0000644- Patch #1180296: Two new functions were added to the locale module:
645 format_string() to get the effect of "format % items" but locale-aware,
646 and currency() to format a monetary number with currency sign.
647
Georg Brandle3a25832006-05-17 14:56:04 +0000648- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
649 and several features added, such as speed and geometry control.
650
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000651- Patch #1488881: add support for external file objects in bz2 compressed
652 tarfiles.
653
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000654- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
655 stdout arguments, making it possible to redirect input and output
656 for remote debugging.
657
658- Patch #1484695: Update the tarfile module to version 0.8. This fixes
659 a couple of issues, notably handling of long file names using the
660 GNU LONGNAME extension.
661
662- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
663 new flag when ``name`` is already the name of an option flag.

666 package.
667
668- Patch #1472854: make the rlcompleter.Completer class usable on non-
669 UNIX platforms.
670
671- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
672
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000673- Bug #1472827: correctly escape newlines and tabs in attribute values in
674 the saxutils.XMLGenerator class.

703
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000704What's New in Python 2.5 alpha 2?
705=================================
706
707*Release date: 27-APR-2006*
708
709Core and builtins
710-----------------
711
Thomas Heller1b046642006-04-18 18:51:06 +0000712- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
713 by converting these apis from macros into exported functions again:
714
715 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
716 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
717 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
718 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
719 PyRun_String Py_CompileString
720
Martin v. Löwis45294a92006-04-18 06:24:08 +0000721- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
722
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000723- All uses of PyStructSequence_InitType have been changed to initialize
724 the type objects only once, even if the interpreter is initialized
725 multiple times.
726
Neal Norwitz61546162006-04-14 05:20:28 +0000727- Bug #1454485, array.array('u') could crash the interpreter. This was
728 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
729 to unicode when it didn't make sense. 'u#' now requires a unicode string.
730
731- Py_UNICODE is unsigned. It was always documented as unsigned, but
732 due to a bug had a signed value in previous versions.
733
Tim Peters3a5e8b12006-04-11 01:44:07 +0000734- Patch #837242: ``id()`` of any Python object always gives a positive
735 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
736 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000737 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000738 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000739
Tim Peters3a5e8b12006-04-11 01:44:07 +0000740 def __hash__(self):
741 return id(self) # WRONG
742
743 because a hash result must be a (short) Python int but it was always
744 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000745 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000746 was always usable as a hash value before this patch. That's no longer
747 necessarily so.
748
749- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000750 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000751 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000752 #1454844)
753
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000754- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
755 involving generators that have paused outside of any ``try`` or ``with``
756 blocks. (In 2.5a1, a paused generator that was part of a reference
757 cycle could not be garbage collected, regardless of whether it was
758 paused in a ``try`` or ``with`` block.)

764 is a macro.
765
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000766- Bug #1467952: os.listdir() now correctly raises an error if readdir()
767 fails with an error condition.
768
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000769- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
770
771- Bug #1117761: bsddb.*open() no longer raises an exception when using
772 the cachesize parameter.
773
774- Bug #1149413: bsddb.*open() no longer raises an exception when using
775 a temporary db (file=None) with the 'n' flag to truncate on open.
776
777- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
778 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000779
Armin Rigoa9017c32006-04-19 11:50:27 +0000780- Patch #1062014: AF_UNIX sockets under Linux have a special
781 abstract namespace that is now fully supported.
782
Anthony Baxter51bcb682006-04-05 14:51:42 +0000783Library
784-------
785
Peter Astrand7d1d4362006-07-14 14:04:45 +0000786- Bug #1223937: subprocess.CalledProcessError reports the exit status
787 of the process using the returncode attribute, instead of
788 abusing errno.
789
Tim Peters711bf302006-04-25 03:31:36 +0000790- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
791 a doctest to be skipped (the code is not run, and the expected output
792 or exception is ignored).
793
Nick Coghlanda2268f2006-04-24 04:37:15 +0000794- Fixed contextlib.nested to cope with exceptions being raised and
795 caught inside exit handlers.
796
Greg Wardab05edc2006-04-23 03:47:58 +0000797- Updated optparse module to Optik 1.5.1 (allow numeric constants in
798 hex, octal, or binary; add ``append_const`` action; keep going if
799 gettext cannot be imported; added ``OptionParser.destroy()`` method;
800 added ``epilog`` for better help generation).
801
Tim Peters21fbd572006-04-21 21:18:10 +0000802- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
803 called from a thread spawned as a side effect of importing a module.
804
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000805- The pydoc module now supports documenting packages contained in
806 .zip or .egg files.
807
808- The pkgutil module now has several new utility functions, such
809 as ``walk_packages()`` to support working with packages that are either
810 in the filesystem or zip files.
811
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000812- The mailbox module can now modify and delete messages from
813 mailboxes, in addition to simply reading them. Thanks to Gregory
814 K. Johnson for writing the code, and to the 2005 Google Summer of
815 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000816
Tim Petersc7605f22006-04-17 21:12:33 +0000817- The ``__del__`` method of class ``local`` in module ``_threading_local``
818 returned before accomplishing any of its intended cleanup.
819
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000820- Patch #790710: Add breakpoint command lists in pdb.
821
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000822- Patch #1063914: Add Tkinter.Misc.clipboard_get().
823
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000824- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
825
Anthony Baxtere29002c2006-04-12 12:07:31 +0000826- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
827 Windows. Bug #1469163.
828
Phillip J. Eby47032112006-04-11 01:07:43 +0000829- The warnings, linecache, inspect, traceback, site, and doctest modules
830 were updated to work correctly with modules imported from zipfiles or
831 via other PEP 302 __loader__ objects.
832
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000833- Patch #1467770: Reduce usage of subprocess._active to processes which
834 the application hasn't waited on.
835
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000836- Patch #1462222: Fix Tix.Grid.
837
Neal Norwitza31bf182006-04-09 03:35:43 +0000838- Fix exception when doing glob.glob('anything*/')
839
Skip Montanaro262fb922006-04-21 02:31:07 +0000840- The pstats.Stats class accepts an optional stream keyword argument to
841 direct output to an alternate file-like object.
842
Anthony Baxter51bcb682006-04-05 14:51:42 +0000843Build
844-----
845
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000846- The Makefile now has a reindent target, which runs reindent.py on
847 the library.
848
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000849- Patch #1470875: Building Python with MS Free Compiler
850
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000851- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000852
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000853- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
854 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000855 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000856 CXX from --with-cxx-main, see description in README.
857
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000858- Patch #1429775: Link extension modules with the shared libpython.
859
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000860- Fixed a libffi build problem on MIPS systems.
861
Tim Peters8931ff12006-05-13 23:28:20 +0000862- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
863 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
864 and "%zu" for unsigned integers of type ``size_t``.
865
Anthony Baxter51bcb682006-04-05 14:51:42 +0000866Tests
867-----
868
Nick Coghlanda2268f2006-04-24 04:37:15 +0000869- test_contextlib now checks contextlib.nested can cope with exceptions
870 being raised and caught inside exit handlers.
871
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000872- test_cmd_line now checks operation of the -m and -c command switches
873
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000874- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
875 it separately and by hand. It also wasn't cleaning up its changes to
876 the current Decimal context.
877
Thomas Woutersabd08882006-04-26 15:53:30 +0000878- regrtest.py now has a -M option to run tests that test the new limits of
879 containers, on 64-bit architectures. Running these tests is only sensible
880 on 64-bit machines with more than two gigabytes of memory. The argument
881 passed is the maximum amount of memory for the tests to use.

890-------------
891
Tim Petersb06d28c2006-05-12 01:57:59 +0000892- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
893
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000894- PEP 343: Added Context Types section to the library reference
895 and attempted to bring other PEP 343 related documentation into
896 line with the implementation and/or python-dev discussions.
897
Tim Peters8dc73d22006-04-24 02:03:16 +0000898- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000902What's New in Python 2.5 alpha 1?
903=================================
904
Anthony Baxterebed3f62006-04-03 15:03:44 +0000905*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000906
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000907Core and builtins
908-----------------
909
Nick Coghlan43832302006-04-23 17:04:07 +0000910- PEP 338: -m command line switch now delegates to runpy.run_module
911 allowing it to support modules in packages and zipfiles
912
Martin v. Löwisc661b882006-04-20 04:54:23 +0000913- On Windows, .DLL is not an accepted file name extension for
914 extension modules anymore; extensions are only found if they
915 end in .PYD.
916
Martin v. Löwisea62d252006-04-03 10:56:49 +0000917- Bug #1421664: sys.stderr.encoding is now set to the same value as
918 sys.stdout.encoding.
919
Neal Norwitz92e212f2006-04-03 04:48:37 +0000920- __import__ accepts keyword arguments.
921
Georg Brandlccadf842006-03-31 18:54:53 +0000922- Patch #1460496: round() now accepts keyword arguments.
923
Anthony Baxter262c00a2006-03-30 10:53:17 +0000924- Fixed bug #1459029 - unicode reprs were double-escaped.
925
Hye-Shik Changd478f342006-03-23 12:32:36 +0000926- Patch #1396919: The system scope threads are reenabled on FreeBSD
927 5.4 and later versions.
928
Neal Norwitze98ccf62006-03-23 05:39:47 +0000929- Bug #1115379: Compiling a Unicode string with an encoding declaration
930 now gives a SyntaxError.
931
Georg Brandlabd1ff82006-03-18 07:59:59 +0000932- Previously, Python code had no easy way to access the contents of a
933 cell object. Now, a ``cell_contents`` attribute has been added
934 (closes patch #1170323).
935
Tim Peterscf79aac2006-03-16 01:14:46 +0000936- Patch #1123430: Python's small-object allocator now returns an arena to
937 the system ``free()`` when all memory within an arena becomes unused
938 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
939 freed. Some applications will see a drop in virtual memory size now,
940 especially long-running applications that, from time to time, temporarily
941 use a large number of small objects. Note that when Python returns an
942 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000943 platform C library will in turn return that memory to the operating system.
944 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000945 appears to be effective at least on Microsoft C and gcc-based systems.
946 Thanks to Evan Jones for hard work and patience.
947
Georg Brandl533ff6f2006-03-08 18:09:27 +0000948- Patch #1434038: property() now uses the getter's docstring if there is
949 no "doc" argument given. This makes it possible to legitimately use
950 property() as a decorator to produce a read-only property.
951
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000952- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
953 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
954 of requiring an int or long in slicing and a few other contexts, enabling
955 other objects (e.g. Numeric Python's integers) to be used as slice indices.
956
Neal Norwitz995acdf2006-03-07 05:01:00 +0000957- Fixed various bugs reported by Coverity's Prevent tool.
958
Brett Cannonbf364092006-03-01 04:25:17 +0000959- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
960 new exception base class, BaseException, which has a new message attribute.
961 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
962 Raising a string exception now raises a DeprecationWarning.
963
Thomas Woutersfb609f42006-02-28 16:37:25 +0000964- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
965 explicitly relative, using 'from .module import name' to mean 'from the same
966 package as this module is in. Imports without dots still default to the
967 old relative-then-absolute, unless 'from __future__ import
968 absolute_import' is used.
969
Brett Cannona7446e32006-02-27 23:39:10 +0000970- Properly check if 'warnings' raises an exception (usually when a filter set
971 to "error" is triggered) when raising a warning for raising string
972 exceptions.
973
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000974- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000975 The name was removed from Include/code.h.
976
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000977- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000978
Guido van Rossum1968ad32006-02-25 22:38:04 +0000979- Patch 1433928:
980 - The copy module now "copies" function objects (as atomic objects).
981 - dict.__getitem__ now looks for a __missing__ hook before raising
982 KeyError.
983
Tim Peters84ef21c2006-02-28 20:39:06 +0000984- PEP 343: with statement implemented. Needs ``from __future__ import
985 with_statement``. Use of 'with' as a variable will generate a warning.
986 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000987 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000988 The following objects have __context__ methods:
989 - The built-in file type.
990 - The thread.LockType type.
991 - The following types defined by the threading module:
992 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
993 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000994
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000995- Fix the encodings package codec search function to only search
996 inside its own package. Fixes problem reported in patch #1433198.
997
998 Note: Codec packages should implement and register their own
999 codec search function. PEP 100 has the details.
1000
Tim Peters9ea89d22006-06-04 03:26:02 +00001001- PEP 353: Using ``Py_ssize_t`` as the index type.
1002
1003- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1004 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1005 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1006 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1007 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001008
Neal Norwitzfc76d632006-01-10 06:03:13 +00001009- Patch #1400181, fix unicode string formatting to not use the locale.
1010 This is how string objects work. u'%f' could use , instead of .
1011 for the decimal point. Now both strings and unicode always use periods.
1012
Neal Norwitz671b9e32006-01-09 07:07:12 +00001013- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1014 configure would break checking curses.h.
1015
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001016- Bug #959576: The pwd module is now builtin. This allows Python to be
1017 built on UNIX platforms without $HOME set.
1018
Neal Norwitzc10978f2005-12-19 06:07:16 +00001019- Bug #1072182, fix some potential problems if characters are signed.
1020
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001021- Bug #889500, fix line number on SyntaxWarning for global declarations.
1022
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001023- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1024
Neal Norwitze7214a12005-12-18 05:03:17 +00001025- Support for converting hex strings to floats no longer works.
1026 This was not portable. float('0x3') now raises a ValueError.
1027
Barry Warsaw2a38a862005-12-18 01:27:35 +00001028- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001029 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001030 is now displayed in interactive prompt banner.
1031
Georg Brandlfa166682005-12-17 21:45:17 +00001032- Implementation of PEP 341 - Unification of try/except and try/finally.
1033 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001034 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001035
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001036- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1037 now encodes backslash correctly.
1038
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001039- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1040
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001041- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001042 and long longs.
1043
Neal Norwitz67715f02005-11-09 06:59:35 +00001044- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001045 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001046 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001047
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001048- Replaced most Unicode charmap codecs with new ones using the
1049 new Unicode translate string feature in the builtin charmap
1050 codec; the codecs were created from the mapping tables available
1051 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1052 encodings now include a mapping for the Apple logo)
1053
Tim Peterse3547fd2005-12-16 23:13:57 +00001054- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001055
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001056- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001057
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001058- A new AST parser implementation was completed. The abstract
1059 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001060 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001061
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001062- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001063 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1064
Neal Norwitz708e51a2005-10-03 04:48:15 +00001065- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1066
Neal Norwitz11bd1192005-10-03 00:54:56 +00001067- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1068 Provide a warning when a directory is passed on the command line.
1069
Neal Norwitz40d37812005-10-02 01:48:49 +00001070- Fix segfault with invalid coding.
1071
1072- SF bug #772896: unknown encoding results in MemoryError.
1073
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001074- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001075 supported a __len__() method which evaluated to False when the iterator
1076 was empty.
1077
Guido van Rossum630db602005-09-20 18:49:54 +00001078- On 64-bit platforms, when __len__() returns a value that cannot be
1079 represented as a C int, raise OverflowError.
1080
Skip Montanarof8948ca2005-09-19 03:54:46 +00001081- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001082 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001083
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001084- SF bug #893549: parsing keyword arguments was broken with a few format
1085 codes.
1086
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001087- Changes donated by Elemental Security to make it work on AIX 5.3
1088 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1089 bug #105470: test_pwd fails on 64bit system (Opteron).
1090
Guido van Rossum539c6622005-09-14 17:49:54 +00001091- Changes donated by Elemental Security to make it work on HP-UX 11 on
1092 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1093
Georg Brandl4550b8d2005-08-26 06:43:52 +00001094- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001095 (fixes bug #1119418).
1096
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001097- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1098
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001099- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1100 exceptions that cause a function to exit.
1101
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001102- The implementation of set() and frozenset() was revised to use its
1103 own internal data structure. Memory consumption is reduced by 1/3
1104 and there are modest speed-ups as well. The API is unchanged.
1105
Tim Petersde7990b2005-07-17 23:45:23 +00001106- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1107
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001108- SF bug #1229429: PyObject_CallMethod failed to decrement some
1109 reference counts in some error exit cases.
1110
Tim Petersecc6e6a2005-07-10 22:30:55 +00001111- SF bug #1185883: Python's small-object memory allocator took over
1112 a block managed by the platform C library whenever a realloc specified
1113 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001114 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001115 portable way to copy data from the C-managed block into Python's
1116 small-object space without risking a memory fault. Python's small-object
1117 realloc now leaves such blocks under the control of the platform C
1118 realloc.
1119
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001120- SF bug #1232517: An overflow error was not detected properly when
1121 attempting to convert a large float to an int in os.utime().
1122
Raymond Hettinger3296e692005-06-29 23:29:56 +00001123- SF bug #1224347: hex longs now print with lowercase letters just
1124 like their int counterparts.
1125
Michael W. Hudson188d4362005-06-20 16:52:57 +00001126- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1127 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1128 interpreter states; back out that fix and do a better job (see
1129 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1130 for a longer write-up of the problem).
1131
Michael W. Hudsondf888462005-06-03 14:41:55 +00001132- SF patch #1180995: marshal now uses a binary format by default when
1133 serializing floats.
1134
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001135- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1136 the routines that promise to produce IEEE 754 binary representations
1137 of floats now simply copy bytes around.
1138
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001139- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1140 278.
1141
Brett Cannonc3647ac2005-04-26 03:45:26 +00001142- patch #1109424: int, long, float, complex, and unicode now check for the
1143 proper magic slot for type conversions when subclassed. Previously the
1144 magic slot was ignored during conversion. Semantics now match the way
1145 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001146 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001147 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001148 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001149
Barry Warsawc8d907c2005-04-19 23:43:40 +00001150- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1151 NULL, now raise an AttributeError when attempting to set or delete the
1152 attribute. Previously a TypeError was raised, but this was inconsistent
1153 with the equivalent pure-Python implementation.
1154
Michael W. Hudson774479c2005-04-18 08:46:17 +00001155- It is now safe to call PyGILState_Release() before
1156 PyEval_InitThreads() (note that if there is reason to believe there
1157 are multiple threads around you still must call PyEval_InitThreads()
1158 before using the Python API; this fix is for extension modules that
1159 have no way of knowing if Python is multi-threaded yet).
1160
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001161- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1162 disabled caused a crash.
1163
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001164- Bug #1165306: instancemethod_new allowed the creation of a method
1165 with im_class == im_self == NULL, which caused a crash when called.
1166
Tim Petersecc6e6a2005-07-10 22:30:55 +00001167- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001168 fixes the crash seen in bug #1165761
1169
Raymond Hettinger96229b12005-03-11 06:49:40 +00001170- Added two new builtins, any() and all().
1171
Brett Cannon409d8f22005-03-05 06:47:57 +00001172- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001173 (e.g., ``class C(): pass`` is no longer a syntax error).
1174 Patch #1176012 added support to the 'parser' module and 'compiler' package
1175 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001176
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001177- Patch #1115086: Support PY_LONGLONG in structmember.
1178
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001179- Bug #1155938: new style classes did not check that __init__() was
1180 returning None.
1181
Tim Petersecc6e6a2005-07-10 22:30:55 +00001182- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001183 ('\') with a specific error message.
1184
Martin v. Löwisff232d72005-03-03 09:24:38 +00001185- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1186
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001187- Bug #1124295: the __name__ attribute of file objects was
1188 inadvertently made inaccessible in restricted mode.
1189
Tim Petersecc6e6a2005-07-10 22:30:55 +00001190- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001191 an ferror() call.
1192
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001193- min() and max() now support key= arguments with the same meaning as in
1194 list.sort().
1195
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001196- The peephole optimizer now performs simple constant folding in expressions:
1197 (2+3) --> (5).
1198
Raymond Hettingera422c342005-01-11 03:03:27 +00001199- set and frozenset objects can now be marshalled. SF #1098985.
1200
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001201- Bug #1077106: Poor argument checking could cause memory corruption
1202 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001203
Jeremy Hyltonab630502005-02-04 18:44:06 +00001204- The parser did not complain about future statements in illegal
1205 positions. It once again reports a syntax error if a future
1206 statement occurs after anything other than a doc string.
1207
Neil Schemenauercf52c072005-08-12 17:34:58 +00001208- Change the %s format specifier for str objects so that it returns a
1209 unicode instance if the argument is not an instance of basestring and
1210 calling __str__ on the argument returns a unicode instance.
1211
Tim Petersf4e69282006-02-27 17:15:31 +00001212- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1213 current thread state when the auto-GIL-state machinery knows about
1214 it (since the thread state is being deleted, continuing to remember it
1215 can't help, but can hurt if another thread happens to get created with
1216 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001408- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1409 been renamed to have only a single underscore prefix. This was done to
1410 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001411
Nick Coghlan43832302006-04-23 17:04:07 +00001412- PEP 338: new module runpy defines a run_module function to support
1413 executing modules which provide access to source code or a code object
1414 via the PEP 302 import mechanisms.
1415
Anthony Baxter93f5b932006-04-03 08:05:07 +00001416- The email module's parsedate_tz function now sets the daylight savings

1424 in attribute values.
1425
Anthony Baxterc51ee692006-04-01 00:57:31 +00001426- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001427 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001428 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001429 module will not be built.
1430
Tim Petersc17976e2006-04-01 00:26:53 +00001431- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1432 aren't officially supported here, and trying to use them will probably
1433 raise an exception some day. But dicts have been allowed, and "mostly
1434 worked", so support for them won't go away without warning.
1435
Georg Brandl338ef7d2006-03-31 18:42:16 +00001436- Bug #1445068: getpass.getpass() can now be given an explicit stream
1437 argument to specify where to write the prompt.
1438
Georg Brandl22ec80b2006-03-31 18:25:44 +00001439- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1454
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001455- email 4.0 package now integrated. This is largely the same as the email 3.0
1456 package that was included in Python 2.3, except that PEP 8 module names are
1457 now used (e.g. mail.message instead of email.Message). The MIME classes
1458 have been moved to a subpackage (e.g. email.mime.text instead of
1459 email.MIMEText). The old names are still supported for now. Several
1460 deprecated Message methods have been removed and lots of bugs have been
1461 fixed. More details can be found in the email package documentation.
1462
Walter Dörwald40108c92006-03-27 08:15:44 +00001463- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1464 (a subclass of tuple) that provides incremental decoders and encoders
1465 (a way to use stateful codecs without the stream API). Python functions
1466 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1467 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1468 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001469
Walter Dörwald067db482006-03-15 22:17:27 +00001470- Patch #1359365: Calling next() on a closed StringIO.String object raises
1471 a ValueError instead of a StopIteration now (like file and cString.String do).
1472 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1473 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001474
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001475- A regrtest option -w was added to re-run failed tests in verbose mode.

1478 interpreter to exit.
1479
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001480- The function get_count() has been added to the gc module, and gc.collect()
1481 grew an optional 'generation' argument.
1482
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001483- A library msilib to generate Windows Installer files, and a distutils

1552 "The consensus of researchers in this area (at least as
1553 expressed at the NIST Hash Function Workshop 10/31/05),
1554 is that SHA-256 is a good choice for the time being, but
1555 that research should continue, and other alternatives may
1556 arise from this research. The larger SHA's also seem OK."

Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001741 + Dialect parameter parsing has been re-implemented to improve error
1742 reporting.
1743 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1744 dictates.
1745 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001746 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001747 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001748 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1749 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001750 + reader now allows \r characters to be quoted (previously it only allowed
1751 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001752 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001753 + Dialect classes passed to the module are no longer instantiated by
1754 the module before being parsed (the former validation scheme required
1755 this, but the mechanism was unreliable).
1756 + The dialect registry now contains instances of the internal
1757 C-coded dialect type, rather than references to python objects.
1758 + the internal c-coded dialect type is now immutable.
1759 + register_dialect now accepts the same keyword dialect specifications
1760 as the reader and writer, allowing the user to register dialects
1761 without first creating a dialect class.
1762 + a configurable limit to the size of parsed fields has been added -
1763 previously, an unmatched quote character could result in the entire
1764 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001765 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001766 the parser field size limit (returning the former limit). The initial
1767 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001768 + A line_num attribute has been added to the reader object, which tracks
1769 the number of lines read from the source iterator. This is not
1770 the same as the number of records returned, as records can span
1771 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001772 + reader and writer objects were not being registered with the cyclic-GC.
1773 This has been fixed.
1774
Brett Cannone6539c42005-01-08 02:43:53 +00001775- _DummyThread objects in the threading module now delete self.__block that is
1776 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1777 lock primitives tend to be limited in number and thus should not be wasted on
1778 a _DummyThread object. Fixes bug #1089632.
1779
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001780- The imghdr module now detects Exif files.
1781
Raymond Hettinger6065d322004-12-20 23:51:53 +00001782- StringIO.truncate() now correctly adjusts the size attribute.
1783 (Bug #951915).
1784
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001785- locale.py now uses an updated locale alias table (built using
1786 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1787 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001788 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001789
Raymond Hettinger3557f422004-12-07 12:02:02 +00001790- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1791
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001792- the pickle module no longer accepts the deprecated None option in the
1793 args tuple returned by __reduce__().
1794
Brett Cannon84667c02004-12-07 03:25:18 +00001795- optparse now optionally imports gettext. This allows its use in setup.py.
1796
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001797- the pickle module no longer uses the deprecated bin parameter.
1798
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001799- the shelve module no longer uses the deprecated binary parameter.
1800
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001801- the pstats module no longer uses the deprecated ignore() method.
1802
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001803- the filecmp module no longer uses the deprecated use_statcache argument.
1804
Raymond Hettinger664347b2004-12-04 21:21:53 +00001805- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1806 extended or overridden by subclasses. Formerly, the subclassed method would
1807 be ignored by the rest of the module. (Bug #1078905).
1808
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001809- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001810 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001811
Walter Dörwald36733692004-12-22 12:50:50 +00001812- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1813 once when a size argument is given. This prevents a buffer overflow in the
1814 tokenizer with very long source lines.
1815
Barry Warsaw538561e2006-01-01 21:48:54 +00001816- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1817 immediately after creating the object, without any intervening
1818 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001819
Skip Montanaro05885812005-01-16 20:48:27 +00001820- The reconvert.quote function can now emit triple-quoted strings. The
1821 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001822
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001823- ``UserString.MutableString`` now supports negative indices in
1824 ``__setitem__`` and ``__delitem__``
1825
Greg Ward40407942005-03-05 02:53:17 +00001826- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1827 correctly.
1828
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001829- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1830 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1831 character even if the user has passed a size parameter to get a proper
1832 line ending. Remove the special handling of a "\r\n" that has been split
1833 between two lines.
1834
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001835- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1836 about illegal code points. The codec now supports PEP 293 style error
1837 handlers.
1838
Walter Dörwald78a78b02005-09-01 12:04:29 +00001839- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001840 from the input stream, so that the output is a byte string in the correct
1841 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001842
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001843- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1844 considering it exactly like a '*'.
1845
Walter Dörwald007f8df2005-10-09 19:42:27 +00001846- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1847 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001848
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001849- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1850
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001851- Patch #1413711: Certain patterns of differences were making difflib
1852 touch the recursion limit.
1853
Walter Dörwald58917a62006-03-31 15:26:22 +00001854- Bug #947906: An object oriented interface has been added to the calendar
1855 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001856 called as a script (e.g. via ``python -mcalendar``). Localized month and
1857 weekday names can be ouput (even if an exotic encoding is used) using
1858 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001859
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001860Build
1861-----
1862
Neal Norwitz602d3392006-03-31 08:21:40 +00001863- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1864 by using -mieee gcc option.
1865

1867
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001868- Build support for Win64-AMD64 was added.
1869
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001870- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1871
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001872- Patch #881820: look for openpty and forkpty also in libbsd.
1873
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001874- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1875 The zlib module is now builtin on Windows.
1876
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001877- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1878
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001879- Bug #1189330: configure did not correctly determine the necessary
1880 value of LINKCC if python was built with GCC 4.0.
1881
Trent Mick8321b422005-07-26 02:29:21 +00001882- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1883 vulnerability in zlib 1.2.1 and 1.2.2.
1884
Brett Cannon08cd5982005-04-24 22:26:38 +00001885- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1886 flags that change binary compatibility. Changes were also made to
1887 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001888 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001889
Bob Ippolitoed233462005-03-29 13:47:59 +00001890- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1891 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1892 no longer exists). This configure patch makes things right.
1893
Martin v. Löwise2713be2005-03-08 15:03:08 +00001894- Bug #1158607: Build with --disable-unicode again.
1895
Brett Cannon46d96232005-02-16 00:07:19 +00001896- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1897 defined. Discovered as a result of not being able to build on OS X.
1898
Brett Cannon516592f2004-12-07 00:42:59 +00001899- setup.py now uses the directories specified in LDFLAGS using the -L option
1900 and in CPPFLAGS using the -I option for adding library and include
1901 directories, respectively, for compiling extension modules against. This has
1902 led to the core being compiled using the values in CPPFLAGS. It also removes
1903 the need for the special-casing of both DarwinPorts and Fink for darwin since
1904 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1905 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1906 Fink, ``-I/opt/local/include`` for DarwinPorts).
1907
Brett Cannon43802422005-02-10 20:48:03 +00001908- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1909 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1910 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1911 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001913C API
1914-----
1915
Tim Petersc9d78aa2006-03-26 23:27:58 +00001916- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1917 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1918 is obtained via the ``PyObject_`` family, it must be released via the
1919 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1920 always been officially true, but when Python's small-object allocator was
1921 introduced, an attempt was made to cater to a few extension modules
1922 discovered at the time that obtained memory via ``PyObject_New`` but
1923 released it via ``PyMem_DEL``. It's years later, and if such code still
1924 exists it will fail now (probably with segfaults, but calling wrong
1925 low-level memory management functions can yield many symptoms).
1926
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001927- Added a C API for set and frozenset objects.
1928
Raymond Hettinger66517482004-12-03 11:45:13 +00001929- Removed PyRange_New().
1930
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001931- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1932 mapping argument now. This string is used as a mapping table. Byte values
1933 greater than the length of the string and 0xFFFE are treated as undefined
1934 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001941
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001942- Patch #1276356: New resource "urlfetch" is implemented. This enables
