Fred Drake53912162006-07-29 13:22:49 +00007What's New in Python 2.5 beta 3?
8================================
Neal Norwitza1f10902006-07-12 07:28:29 +00009
10*Release date: XX-AUG-2006*
11
12Core and builtins
13-----------------
14
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000015- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
16 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
17 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
18 excessive filesystem operations during imports.
19
Tim Petersbc24eee2006-07-27 01:14:53 +000020- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
21 operations on signed longs that are formally undefined by C.
22 Unfortunately, at least one compiler now cares about that, so complicated
23 the code to make that compiler happy again.
24
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000025- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
26
Martin v. Löwisd22968a2006-07-24 11:54:53 +000027- Patch #1232023: Stop including current directory in search
28 path on Windows.
29
Neal Norwitze1fdb322006-07-21 05:32:28 +000030- Fix some potential crashes found with failmalloc.
31
Neal Norwitze7563102006-07-17 01:00:16 +000032- Fix warnings reported by Klocwork's static analysis tool.
33
Neal Norwitz84be93b2006-07-16 01:50:38 +000034- Bug #1512814, Fix incorrect lineno's when code within a function
35 had more than 255 blank lines.
36
Georg Brandl9dceedb2006-07-12 15:31:17 +000037- Patch #1521179: Python now accepts the standard options ``--help`` and
38 ``--version`` as well as ``/?`` on Windows.
39
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000040- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000041 again. Fixing this problem required changing the .pyc magic number.
42 This means that .pyc files generated before 2.5c1 will be regenerated.
43
Tim Peters112aad32006-07-19 00:03:19 +000044- Bug #1524317: Compiling Python ``--without-threads`` failed.
45 The Python core compiles again then, and, in a build without threads, the
46 new ``sys._current_frames()`` returns a dictionary with one entry,
47 mapping the faux "thread id" 0 to the current frame.
48
Ronald Oussoren3075e162006-07-25 20:28:55 +000049- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000050
Ronald Oussoren3075e162006-07-25 20:28:55 +000051
Neal Norwitza1f10902006-07-12 07:28:29 +000052Library
53-------
54
Georg Brandledd9b0d2006-07-29 09:33:26 +000055- Bug #1441397: The compiler module now recognizes module and function
56 docstrings correctly as it did in Python 2.4.
57
Tim Peters6f681472006-07-27 23:44:37 +000058- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
59 lost that tests are sorted by name before being run. This rarely
60 matters for well-written tests, but can create baffling symptoms if
61 side effects from one test to the next affect outcomes. ``DocTestFinder``
62 has been changed to sort the list of tests it returns.
63
Martin v. Löwis997ceff2006-07-27 06:38:16 +000064- The distutils version has been changed to 2.5.0.
65
Martin v. Löwis9298eff2006-07-26 12:12:56 +000066- Bug #978833: Really close underlying socket in _socketobject.close.
67
Georg Brandl0619a322006-07-26 07:40:17 +000068- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
69 with title().
70
Georg Brandlcf0c1722006-07-26 07:23:32 +000071- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
72 to recursive calls and call it with the failing package name.
73
Martin v. Löwis0b483032006-07-25 09:53:12 +000074- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
75
Georg Brandlc13c34c2006-07-24 14:09:56 +000076- Patch #1515343: Fix printing of deprecated string exceptions with a
77 value in the traceback module.
78
Greg Ward48fae7a2006-07-23 16:05:51 +000079- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
80
Martin v. Löwis426f4a12006-07-18 17:46:31 +000081- Patch #1524429: Use repr() instead of backticks in Tkinter again.
82
Brett Cannoncaebe222006-07-18 04:41:36 +000083- Bug #1520914: Change time.strftime() to accept a zero for any position in its
84 argument tuple. For arguments where zero is illegal, the value is forced to
85 the minimum value that is correct. This is to support an undocumented but
86 common way people used to fill in inconsequential information in the time
87 tuple pre-2.4.
88
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000089- Patch #1220874: Update the binhex module for Mach-O.
90
Barry Warsawb110bad2006-07-21 14:51:07 +000091- The email package has improved RFC 2231 support, specifically for
92 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
93 (name*0=<blah>) parameter continuations. This may change the types of
94 values returned from email.message.Message.get_param() and friends.
95 Specifically in some cases where non-encoded continuations were used,
96 get_param() used to return a 3-tuple of (None, None, string) whereas now it
97 will just return the string (since non-encoded continuations don't have
98 charset and language parts).
99
100 Also, whereas % values were decoded in all parameter continuations, they are
101 now only decoded in encoded parameter parts.
102
Ronald Oussoren3075e162006-07-25 20:28:55 +0000103- Bug #1517990: IDLE keybindings on MacOS X now work correctly
104
105- Bug #1517996: IDLE now longer shows the default Tk menu when a
106 path browser, class browser or debugger is the frontmost window on MacOS X
107
Barry Warsaw00decd72006-07-27 23:43:15 +0000108- Patch #1520294: Support for getset and member descriptors in types.py,
109 inspect.py, and pydoc.py. Specifically, this allows for querying the type
110 of an object against these built-in types and more importantly, for getting
111 their docstrings printed in the interactive interpreter's help() function.
112
Ronald Oussoren3075e162006-07-25 20:28:55 +0000113
Neal Norwitza1f10902006-07-12 07:28:29 +0000114Extension Modules
115-----------------
116
Thomas Heller1393d6a2006-07-28 21:43:20 +0000117- Patch #1529514: The _ctypes extension is now compiled on more
118 openbsd target platforms.
119
Tim Peters9cab5932006-07-28 00:30:00 +0000120- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
121 a memory leak, affecting pickles and deep copies.
122
Tim Petersbc24eee2006-07-27 01:14:53 +0000123- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000124 Paul Eggert.
125
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000126- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
127
Thomas Hellerce049a02006-07-14 17:51:14 +0000128- Patch #1521817: Index range checking on ctypes arrays containing
129 exactly one element enabled again. This allows iterating over these
130 arrays, without the need to check the array size before.
131
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000132- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000133 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000134 /dev/null in certain cases; this is now fixed.
135
Thomas Heller47d7a062006-07-12 08:43:47 +0000136- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
137 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000138
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000139- Because of a misspelled preprocessor symbol, ctypes was always
140 compiled without thread support; this is now fixed.
141
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000142- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
143 methods now allow their database parameter to be None as the
144 sleepycat API allows.
145
Matt Flemingec926502006-07-28 11:27:27 +0000146- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
147 bluetooth API compared with Linux and FreeBSD.
148
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000149Tests
150-----
151
152- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
153 how long the test file should take to play. Now accepts taking 2.93 secs
154 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
155
Georg Brandl4793aa32006-07-28 18:31:39 +0000156- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
157 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
158 run via ``regrtest.py``. Now they do.

166Core and builtins
167-----------------
168
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000169- Bug #1441486: The literal representation of -(sys.maxint - 1)
170 again evaluates to a int object, not a long.
171
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000172- Bug #1501934: The scope of global variables that are locally assigned
173 using augmented assignment is now correctly determined.
174
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000175- Bug #927248: Recursive method-wrapper objects can now safely
176 be released.
177
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000178- Bug #1417699: Reject locale-specific decimal point in float()
179 and atof().
180
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000181- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
182 omit a default "error" argument for NULL pointer. This allows
183 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000184
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000185- Bug #1519018: 'as' is now validated properly in import statements.
186
Neal Norwitz28746ab2006-07-09 22:14:42 +0000187- On 64 bit systems, int literals that use less than 64 bits are
188 now ints rather than longs.
189
Neal Norwitzed657552006-07-10 00:04:44 +0000190- Bug #1512814, Fix incorrect lineno's when code at module scope
191 started after line 256.
192
Tim Peters32a83612006-07-10 21:08:24 +0000193- New function ``sys._current_frames()`` returns a dict mapping thread
194 id to topmost thread stack frame. This is for expert use, and is
195 especially useful for debugging application deadlocks. The functionality
196 was previously available in Fazal Majid's ``threadframe`` extension
197 module, but it wasn't possible to do this in a wholly threadsafe way from
198 an extension.
199
Georg Brandlad29e632006-06-21 17:45:17 +0000200Library
201-------
202
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000203- Patch #1519566: Update turtle demo, make begin_fill idempotent.
204

Martin v. Löwis8d656812006-07-10 07:23:48 +0000206 environment variable to be set in order to the SDK environment
207 for finding the compiler, include files, etc.
208
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000209- Bug #1515998: Properly generate logical ids for files in bdist_msi.

212
Thomas Woutersadd19112006-07-05 11:03:49 +0000213- string.Template() now correctly handles tuple-values. Previously,
214 multi-value tuples would raise an exception and single-value tuples would
215 be treated as the value they contain, instead.
216
Martin v. Löwisede77f52006-07-03 13:01:35 +0000217- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
218 even if some data are received.
219
Martin v. Löwis45482392006-07-03 12:28:58 +0000220- Bug #1267547: Put proper recursive setup.py call into the
221 spec file generated by bdist_rpm.
222

224 degrees and radians.
225
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000226- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000227 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000228
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000229- Bug #1514703: Only setup canvas window in turtle when the canvas

239 sgmllib ('[' and ']' were not accepted).
240
Georg Brandl1be63af2006-06-28 20:23:25 +0000241- Fix a bug in the turtle module's end_fill function.
242
Brett Cannon53ab5b72006-06-22 16:49:14 +0000243- Bug #1510580: The 'warnings' module improperly required that a Warning
244 category be either a types.ClassType and a subclass of Warning. The proper
245 check is just that it is a subclass with Warning as the documentation states.
246
Georg Brandlad29e632006-06-21 17:45:17 +0000247- The compiler module now correctly compiles the new try-except-finally
248 statement (bug #1509132).
249
Neal Norwitz60373cd2006-06-22 06:30:50 +0000250- The wsgiref package is now installed properly on Unix.
251
Vinay Sajip28e57612006-07-01 10:45:20 +0000252- A bug was fixed in logging.config.fileConfig() which caused a crash on
253 shutdown when fileConfig() was called multiple times.
254
Gerhard Häring762fbd32006-07-02 17:48:30 +0000255- The sqlite3 module did cut off data from the SQLite database at the first
256 null character before sending it to a custom converter. This has been fixed
257 now.
258
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000259Extension Modules
260-----------------
261
Tim Peters112aad32006-07-19 00:03:19 +0000262- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
263 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
264 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000265
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000266- Assigning None to pointer type fields in ctypes structures possible
267 overwrote the wrong fields, this is fixed now.
268
269- Fixed a segfault in _ctypes when ctypes.wintypes were imported
270 on non-Windows platforms.
271
272- Bug #1518190: The ctypes.c_void_p constructor now accepts any
273 integer or long, without range checking.
274
275- Patch #1517790: It is now possible to use custom objects in the ctypes
276 foreign function argtypes sequence as long as they provide a from_param
277 method, no longer is it required that the object is a ctypes type.
278
279- The '_ctypes' extension module now works when Python is configured
280 with the --without-threads option.
281
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000282- Bug #1513646: os.access on Windows now correctly determines write
283 access, again.
284
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000285- Bug #1512695: cPickle.loads could crash if it was interrupted with
286 a KeyboardInterrupt.
287
Neal Norwitza12aa882006-07-06 06:45:08 +0000288- Bug #1296433: parsing XML with a non-default encoding and
289 a CharacterDataHandler could crash the interpreter in pyexpat.

297
Tim Peters32a83612006-07-10 21:08:24 +0000298- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000299 Previously, the slight difference could cause compilation errors of the
300 'zlib' module on systems with more than one version of zlib.
301
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000302- The MSI compileall step was fixed to also support a TARGETDIR
303 with spaces in it.
304

Anthony Baxter51bcb682006-04-05 14:51:42 +0000331
332Core and builtins
333-----------------
334
Georg Brandla56b9152006-06-19 06:35:54 +0000335- Patch #1507676: Error messages returned by invalid abstract object operations
336 (such as iterating over an integer) have been improved and now include the
337 type of the offending object to help with debugging.
338
Brett Cannonea3912b2006-06-13 21:46:41 +0000339- Bug #992017: A classic class that defined a __coerce__() method that returned
340 its arguments swapped would infinitely recurse and segfault the interpreter.
341
Neal Norwitz909eb122006-06-12 02:13:21 +0000342- Fix the socket tests so they can be run concurrently.
343
Neal Norwitzb9845e72006-06-12 02:11:18 +0000344- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000345 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000346
Brett Cannon22565aa2006-06-09 22:31:23 +0000347- Bug #532646: object.__call__() will continue looking for the __call__
348 attribute on objects until one without one is found. This leads to recursion
349 when you take a class and set its __call__ attribute to an instance of the
350 class. Originally fixed for classic classes, but this fix is for new-style.
351 Removes the infinite_rec_3 crasher.
352
Georg Brandl24250812006-06-09 18:45:48 +0000353- The string and unicode methods startswith() and endswith() now accept
354 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
355
Brett Cannonde3b0522006-06-08 17:00:45 +0000356- Buffer objects, at the C level, never used the char buffer
357 implementation even when the char buffer for the wrapped object was
358 explicitly requested (originally returned the read or write buffer).
359 Now a TypeError is raised if the char buffer is not present but is
360 requested.
361
Georg Brandlddbaa662006-06-04 21:56:52 +0000362- Patch #1346214: Statements like "if 0: suite" are now again optimized
363 away like they were in Python 2.4.
364
Georg Brandlb7c8f542006-05-27 12:30:25 +0000365- Builtin exceptions are now full-blown new-style classes instead of
366 instances pretending to be classes, which speeds up exception handling
367 by about 80% in comparison to 2.5a2.
368
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000369- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
370 Unicode 4.1.
371
Georg Brandlf4ef1162006-05-26 18:03:31 +0000372- Patch #921466: sys.path_importer_cache is now used to cache valid and
373 invalid file paths for the built-in import machinery which leads to
374 fewer open calls on startup.
375
Tim Peters696cf432006-05-24 21:10:40 +0000376- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
377 of-2 bases. The largest speedup is for inputs with about 1000 decimal
378 digits. Conversion from non-power-of-2 bases remains quadratic-time in
379 the number of input digits (it was and remains linear-time for bases
380 2, 4, 8, 16 and 32).
381
Tim Petersb713ec22006-05-23 18:45:30 +0000382- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
383 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
384 an integer close to ``sys.maxint``. This was repaired by patch
385 #1335972, which also gives a nice speedup.
386
Richard Jonescebbefc2006-05-23 18:28:17 +0000387- Patch #1337051: reduced size of frame objects.
388
389- PyErr_NewException now accepts a tuple of base classes as its
390 "base" parameter.
391
Richard Jones7c88dcc2006-05-23 10:37:38 +0000392- Patch #876206: function call speedup by retaining allocated frame
393 objects.
394
Georg Brandl7b90e162006-05-18 07:01:27 +0000395- Bug #1462152: file() now checks more thoroughly for invalid mode
396 strings and removes a possible "U" before passing the mode to the
397 C library function.
398
Neal Norwitz1004a532006-05-15 07:17:23 +0000399- Patch #1488312, Fix memory alignment problem on SPARC in unicode
400
Neal Norwitz373f0a72006-05-15 07:04:36 +0000401- Bug #1487966: Fix SystemError with conditional expression in assignment
402
Martin v. Löwis879768d2006-05-11 13:28:43 +0000403- WindowsError now has two error code attributes: errno, which carries
404 the error values from errno.h, and winerror, which carries the error
405 values from winerror.h. Previous versions put the winerror.h values
406 (from GetLastError()) into the errno attribute.
407
Martin v. Löwis77736712006-05-04 05:51:03 +0000408- Patch #1475845: Raise IndentationError for unexpected indent.
409
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000410- Patch #1479181: split open() and file() from being aliases for each other.
411
Tim Peters44bd9862006-06-01 13:49:23 +0000412- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
413 methods were always silently ignored by dictionaries when comparing keys.
414 They are now passed through (except when using the C API function
415 ``PyDict_GetItem()``, whose semantics did not change).
416
417- Bug #1456209: In some obscure cases it was possible for a class with a
418 custom ``__eq__()`` method to confuse dict internals when class instances
419 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
420 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000422Extension Modules
423-----------------
424

426
427- Patch #1462338: Upgrade pyexpat to expat 2.0.0
428
Brett Cannon6ee7d012006-06-08 16:23:04 +0000429- Change binascii.hexlify to accept a read-only buffer instead of only a char
430 buffer and actually follow its documentation.
431
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000432- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
433
Nick Coghlanc649ec52006-05-29 12:43:05 +0000434- Patch #1478788 (modified version): The functional extension module has
435 been renamed to _functools and a functools Python wrapper module added.
436 This provides a home for additional function related utilities that are
437 not specifically about functional programming. See PEP 309.
438
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000439- Patch #1493701: performance enhancements for struct module.
440
Georg Brandl378d5922006-05-17 14:26:50 +0000441- Patch #1490224: time.altzone is now set correctly on Cygwin.
442
Georg Brandl8d3342b2006-05-16 07:38:27 +0000443- Patch #1435422: zlib's compress and decompress objects now have a
444 copy() method.
445
Andrew MacIntyre92913322006-06-13 15:04:24 +0000446- Patch #1454481: thread stack size is now tunable at runtime for thread
447 enabled builds on Windows and systems with Posix threads support.
448
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000449- On Win32, os.listdir now supports arbitrarily-long Unicode path names
450 (up to the system limit of 32K characters).
451
452- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
453 As a result, these functions now raise WindowsError instead of OSError.
454
Tim Peters7a822da2006-05-25 21:50:17 +0000455- ``time.clock()`` on Win64 should use the high-performance Windows
456 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
457 Windows platforms).
458
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000459- Calling Tk_Init twice is refused if the first call failed as that
460 may deadlock.
461
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000462- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
463 accept it without potentially using an uninitialized pointer.
464
465- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
466 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
467 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000468
Gregory P. Smith372b5832006-06-05 18:48:21 +0000469- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000470 [pybsddb project SF patch number 1466734]
471
Gregory P. Smith372b5832006-06-05 18:48:21 +0000472- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
473 parameter is supplied. [SF pybsddb bug #1477863]
474
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000475- bsddb: the __len__ method of a DB object has been fixed to return correct
476 results. It could previously incorrectly return 0 in some cases.
477 Fixes SF bug 1493322 (pybsddb bug 1184012).
478
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000479- bsddb: the bsddb.dbtables Modify method now raises the proper error and
480 aborts the db transaction safely when a modifier callback fails.
481 Fixes SF python patch/bug #1408584.
482
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000483- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000484 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000485 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
486 database calls that would previously deadlock. [SF python bug #775414]
487
Vinay Sajip28e57612006-07-01 10:45:20 +0000488- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000489

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000496- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
497 functions.
498
Martin v. Löwis3798da02006-06-17 18:44:27 +0000499- Patch #812986: Update turtle output even if not tracing.
500
Vinay Sajip28e57612006-07-01 10:45:20 +0000501- Patch #1494750: Destroy master after deleting children in

503
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000504- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
505
Martin v. Löwis337487e2006-06-17 09:15:14 +0000506- Patch #763580: Add name and value arguments to Tkinter variable
507 classes.
508
Georg Brandl83cc0d02006-06-14 08:50:03 +0000509- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
510 mime.types file for determining MIME types.
511
Georg Brandl2605ca82006-06-14 06:08:31 +0000512- Bug #1339007: Shelf objects now don't raise an exception in their
513 __del__ method when initialization failed.
514
Martin v. Löwisd8251432006-06-14 05:21:04 +0000515- Patch #1455898: The MBCS codec now supports the incremental mode for
516 double-byte encodings.
517
Tim Peters43898b42006-06-14 04:09:25 +0000518- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
519 guarantee that adjacent triples in the return list always describe
520 non-adjacent blocks. Previously, a pair of matching blocks could end
521 up being described by multiple adjacent triples that formed a partition
522 of the matching pair.
523
Greg Ward0e0c9f42006-06-11 16:24:11 +0000524- Bug #1498146: fix optparse to handle Unicode strings in option help,
525 description, and epilog.
526
Greg Wardd1c797e2006-06-11 14:42:41 +0000527- Bug #1366250: minor optparse documentation error.
528
Greg Ward7f547402006-06-11 00:40:49 +0000529- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
530 clarify docs.
531
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000532- The wsgiref package has been added to the standard library.
533
Nick Coghlan676725d2006-06-08 13:54:49 +0000534- The functions update_wrapper() and wraps() have been added to the functools
535 module. These make it easier to copy relevant metadata from the original
536 function when writing wrapper functions.
537
Tim Petersd6a9eef2006-06-05 01:48:21 +0000538- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
539 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000540
Martin v. Löwis3f767792006-06-04 19:36:28 +0000541- Patch #1359618: Speed up charmap encoder by using a trie structure
542 for lookup.
543
Tim Petersd609b1a2006-06-02 23:22:51 +0000544- The functions in the ``pprint`` module now sort dictionaries by key
545 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
546 if and only if its display required more than one line, although that
547 wasn't documented. The new behavior increases predictability; e.g.,
548 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
549
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000550- Patch #1497027: try HTTP digest auth before basic auth in urllib2
551 (thanks for J. J. Lee).
552
Georg Brandl2b330372006-05-28 20:23:12 +0000553- Patch #1496206: improve urllib2 handling of passwords with respect to
554 default HTTP and HTTPS ports.
555
George Yoshidaf3c65de2006-05-28 16:39:09 +0000556- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
557
Bob Ippolito7298f272006-05-23 18:43:47 +0000558- Patch #1281707: speed up gzip.readline.
559
Georg Brandlb89316f2006-05-17 15:51:16 +0000560- Patch #1180296: Two new functions were added to the locale module:
561 format_string() to get the effect of "format % items" but locale-aware,
562 and currency() to format a monetary number with currency sign.
563
Georg Brandle3a25832006-05-17 14:56:04 +0000564- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
565 and several features added, such as speed and geometry control.
566
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000567- Patch #1488881: add support for external file objects in bz2 compressed
568 tarfiles.
569
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000570- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
571 stdout arguments, making it possible to redirect input and output
572 for remote debugging.
573
574- Patch #1484695: Update the tarfile module to version 0.8. This fixes
575 a couple of issues, notably handling of long file names using the
576 GNU LONGNAME extension.
577
578- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
579 new flag when ``name`` is already the name of an option flag.
580
581- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
582 package.
583
584- Patch #1472854: make the rlcompleter.Completer class usable on non-
585 UNIX platforms.
586
587- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000589- Bug #1472827: correctly escape newlines and tabs in attribute values in

625Core and builtins
626-----------------
627
Thomas Heller1b046642006-04-18 18:51:06 +0000628- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
629 by converting these apis from macros into exported functions again:
630
631 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
632 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
633 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
634 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
635 PyRun_String Py_CompileString
636
Martin v. Löwis45294a92006-04-18 06:24:08 +0000637- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
638
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000639- All uses of PyStructSequence_InitType have been changed to initialize
640 the type objects only once, even if the interpreter is initialized
641 multiple times.
642
Neal Norwitz61546162006-04-14 05:20:28 +0000643- Bug #1454485, array.array('u') could crash the interpreter. This was
644 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
645 to unicode when it didn't make sense. 'u#' now requires a unicode string.
646
647- Py_UNICODE is unsigned. It was always documented as unsigned, but
648 due to a bug had a signed value in previous versions.
649
Tim Peters3a5e8b12006-04-11 01:44:07 +0000650- Patch #837242: ``id()`` of any Python object always gives a positive
651 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
652 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000653 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000654 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000655
Tim Peters3a5e8b12006-04-11 01:44:07 +0000656 def __hash__(self):
657 return id(self) # WRONG
658
659 because a hash result must be a (short) Python int but it was always
660 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000661 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000662 was always usable as a hash value before this patch. That's no longer
663 necessarily so.
664
665- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000666 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000667 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000668 #1454844)
669
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000670- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
671 involving generators that have paused outside of any ``try`` or ``with``
672 blocks. (In 2.5a1, a paused generator that was part of a reference
673 cycle could not be garbage collected, regardless of whether it was
674 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000676Extension Modules
677-----------------
678
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000679- Patch #1191065: Fix preprocessor problems on systems where recvfrom
680 is a macro.
681
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000682- Bug #1467952: os.listdir() now correctly raises an error if readdir()
683 fails with an error condition.
684
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000685- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
686
687- Bug #1117761: bsddb.*open() no longer raises an exception when using
688 the cachesize parameter.
689
690- Bug #1149413: bsddb.*open() no longer raises an exception when using
691 a temporary db (file=None) with the 'n' flag to truncate on open.
692
693- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
694 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000695
Armin Rigoa9017c32006-04-19 11:50:27 +0000696- Patch #1062014: AF_UNIX sockets under Linux have a special
697 abstract namespace that is now fully supported.
698
Anthony Baxter51bcb682006-04-05 14:51:42 +0000699Library
700-------
701
Peter Astrand7d1d4362006-07-14 14:04:45 +0000702- Bug #1223937: subprocess.CalledProcessError reports the exit status
703 of the process using the returncode attribute, instead of
704 abusing errno.
705
Tim Peters711bf302006-04-25 03:31:36 +0000706- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
707 a doctest to be skipped (the code is not run, and the expected output
708 or exception is ignored).
709
Nick Coghlanda2268f2006-04-24 04:37:15 +0000710- Fixed contextlib.nested to cope with exceptions being raised and
711 caught inside exit handlers.
712
Greg Wardab05edc2006-04-23 03:47:58 +0000713- Updated optparse module to Optik 1.5.1 (allow numeric constants in
714 hex, octal, or binary; add ``append_const`` action; keep going if
715 gettext cannot be imported; added ``OptionParser.destroy()`` method;
716 added ``epilog`` for better help generation).
717
Tim Peters21fbd572006-04-21 21:18:10 +0000718- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
719 called from a thread spawned as a side effect of importing a module.
720
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000721- The pydoc module now supports documenting packages contained in
722 .zip or .egg files.
723
724- The pkgutil module now has several new utility functions, such
725 as ``walk_packages()`` to support working with packages that are either
726 in the filesystem or zip files.
727
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000728- The mailbox module can now modify and delete messages from
729 mailboxes, in addition to simply reading them. Thanks to Gregory
730 K. Johnson for writing the code, and to the 2005 Google Summer of
731 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000732
Tim Petersc7605f22006-04-17 21:12:33 +0000733- The ``__del__`` method of class ``local`` in module ``_threading_local``
734 returned before accomplishing any of its intended cleanup.
735
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000736- Patch #790710: Add breakpoint command lists in pdb.
737
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000738- Patch #1063914: Add Tkinter.Misc.clipboard_get().
739
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000740- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
741
Anthony Baxtere29002c2006-04-12 12:07:31 +0000742- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
743 Windows. Bug #1469163.
744
Phillip J. Eby47032112006-04-11 01:07:43 +0000745- The warnings, linecache, inspect, traceback, site, and doctest modules
746 were updated to work correctly with modules imported from zipfiles or
747 via other PEP 302 __loader__ objects.
748
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000749- Patch #1467770: Reduce usage of subprocess._active to processes which
750 the application hasn't waited on.
751
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000752- Patch #1462222: Fix Tix.Grid.
753
Neal Norwitza31bf182006-04-09 03:35:43 +0000754- Fix exception when doing glob.glob('anything*/')
755
Skip Montanaro262fb922006-04-21 02:31:07 +0000756- The pstats.Stats class accepts an optional stream keyword argument to
757 direct output to an alternate file-like object.
758
Anthony Baxter51bcb682006-04-05 14:51:42 +0000759Build
760-----
761
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000762- The Makefile now has a reindent target, which runs reindent.py on
763 the library.
764
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000765- Patch #1470875: Building Python with MS Free Compiler
766
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000767- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000768
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000769- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
770 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000771 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000772 CXX from --with-cxx-main, see description in README.
773
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000774- Patch #1429775: Link extension modules with the shared libpython.
775
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000776- Fixed a libffi build problem on MIPS systems.
777
Tim Peters8931ff12006-05-13 23:28:20 +0000778- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
779 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
780 and "%zu" for unsigned integers of type ``size_t``.
781
Anthony Baxter51bcb682006-04-05 14:51:42 +0000782Tests
783-----
784
Nick Coghlanda2268f2006-04-24 04:37:15 +0000785- test_contextlib now checks contextlib.nested can cope with exceptions
786 being raised and caught inside exit handlers.
787
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000788- test_cmd_line now checks operation of the -m and -c command switches
789
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000790- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
791 it separately and by hand. It also wasn't cleaning up its changes to
792 the current Decimal context.
793
Thomas Woutersabd08882006-04-26 15:53:30 +0000794- regrtest.py now has a -M option to run tests that test the new limits of
795 containers, on 64-bit architectures. Running these tests is only sensible
796 on 64-bit machines with more than two gigabytes of memory. The argument
797 passed is the maximum amount of memory for the tests to use.
798
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +0000799Tools
800-----
801
802- Added the Python benchmark suite pybench to the Tools/ directory;
803 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000805Documentation
806-------------
807
Tim Petersb06d28c2006-05-12 01:57:59 +0000808- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
809
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000810- PEP 343: Added Context Types section to the library reference
811 and attempted to bring other PEP 343 related documentation into
812 line with the implementation and/or python-dev discussions.
813
Tim Peters8dc73d22006-04-24 02:03:16 +0000814- Bug #1337990: clarified that ``doctest`` does not support examples
815 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000818What's New in Python 2.5 alpha 1?
819=================================
820
Anthony Baxterebed3f62006-04-03 15:03:44 +0000821*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000822
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000823Core and builtins
824-----------------
825
Nick Coghlan43832302006-04-23 17:04:07 +0000826- PEP 338: -m command line switch now delegates to runpy.run_module
827 allowing it to support modules in packages and zipfiles
828
Martin v. Löwisc661b882006-04-20 04:54:23 +0000829- On Windows, .DLL is not an accepted file name extension for
830 extension modules anymore; extensions are only found if they
831 end in .PYD.
832
Martin v. Löwisea62d252006-04-03 10:56:49 +0000833- Bug #1421664: sys.stderr.encoding is now set to the same value as
834 sys.stdout.encoding.
835
Neal Norwitz92e212f2006-04-03 04:48:37 +0000836- __import__ accepts keyword arguments.
837
Georg Brandlccadf842006-03-31 18:54:53 +0000838- Patch #1460496: round() now accepts keyword arguments.
839
Anthony Baxter262c00a2006-03-30 10:53:17 +0000840- Fixed bug #1459029 - unicode reprs were double-escaped.
841
Hye-Shik Changd478f342006-03-23 12:32:36 +0000842- Patch #1396919: The system scope threads are reenabled on FreeBSD
843 5.4 and later versions.
844
Neal Norwitze98ccf62006-03-23 05:39:47 +0000845- Bug #1115379: Compiling a Unicode string with an encoding declaration
846 now gives a SyntaxError.
847
Georg Brandlabd1ff82006-03-18 07:59:59 +0000848- Previously, Python code had no easy way to access the contents of a
849 cell object. Now, a ``cell_contents`` attribute has been added
850 (closes patch #1170323).
851
Tim Peterscf79aac2006-03-16 01:14:46 +0000852- Patch #1123430: Python's small-object allocator now returns an arena to
853 the system ``free()`` when all memory within an arena becomes unused
854 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
855 freed. Some applications will see a drop in virtual memory size now,
856 especially long-running applications that, from time to time, temporarily
857 use a large number of small objects. Note that when Python returns an
858 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000859 platform C library will in turn return that memory to the operating system.
860 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000861 appears to be effective at least on Microsoft C and gcc-based systems.
862 Thanks to Evan Jones for hard work and patience.
863
Georg Brandl533ff6f2006-03-08 18:09:27 +0000864- Patch #1434038: property() now uses the getter's docstring if there is
865 no "doc" argument given. This makes it possible to legitimately use
866 property() as a decorator to produce a read-only property.
867
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000868- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
869 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
870 of requiring an int or long in slicing and a few other contexts, enabling
871 other objects (e.g. Numeric Python's integers) to be used as slice indices.
872
Neal Norwitz995acdf2006-03-07 05:01:00 +0000873- Fixed various bugs reported by Coverity's Prevent tool.
874
Brett Cannonbf364092006-03-01 04:25:17 +0000875- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
876 new exception base class, BaseException, which has a new message attribute.
877 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
878 Raising a string exception now raises a DeprecationWarning.
879
Thomas Woutersfb609f42006-02-28 16:37:25 +0000880- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
881 explicitly relative, using 'from .module import name' to mean 'from the same
882 package as this module is in. Imports without dots still default to the
883 old relative-then-absolute, unless 'from __future__ import
884 absolute_import' is used.
885
Brett Cannona7446e32006-02-27 23:39:10 +0000886- Properly check if 'warnings' raises an exception (usually when a filter set
887 to "error" is triggered) when raising a warning for raising string
888 exceptions.
889
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000890- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000891 The name was removed from Include/code.h.
892
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000893- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000894
Guido van Rossum1968ad32006-02-25 22:38:04 +0000895- Patch 1433928:
896 - The copy module now "copies" function objects (as atomic objects).
897 - dict.__getitem__ now looks for a __missing__ hook before raising
898 KeyError.
899
Tim Peters84ef21c2006-02-28 20:39:06 +0000900- PEP 343: with statement implemented. Needs ``from __future__ import
901 with_statement``. Use of 'with' as a variable will generate a warning.
902 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000903 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000904 The following objects have __context__ methods:
905 - The built-in file type.
906 - The thread.LockType type.
907 - The following types defined by the threading module:
908 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
909 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000910
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000911- Fix the encodings package codec search function to only search
912 inside its own package. Fixes problem reported in patch #1433198.
913
914 Note: Codec packages should implement and register their own
915 codec search function. PEP 100 has the details.
916
Tim Peters9ea89d22006-06-04 03:26:02 +0000917- PEP 353: Using ``Py_ssize_t`` as the index type.
918
919- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
920 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
921 now allow Python to make use of memory blocks exceeding 2**32 bytes for
922 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
923 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000924
Neal Norwitzfc76d632006-01-10 06:03:13 +0000925- Patch #1400181, fix unicode string formatting to not use the locale.
926 This is how string objects work. u'%f' could use , instead of .
927 for the decimal point. Now both strings and unicode always use periods.
928
Neal Norwitz671b9e32006-01-09 07:07:12 +0000929- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
930 configure would break checking curses.h.
931
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000932- Bug #959576: The pwd module is now builtin. This allows Python to be
933 built on UNIX platforms without $HOME set.
934
Neal Norwitzc10978f2005-12-19 06:07:16 +0000935- Bug #1072182, fix some potential problems if characters are signed.
936
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000937- Bug #889500, fix line number on SyntaxWarning for global declarations.
938
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000939- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
940
Neal Norwitze7214a12005-12-18 05:03:17 +0000941- Support for converting hex strings to floats no longer works.
942 This was not portable. float('0x3') now raises a ValueError.
943
Barry Warsaw2a38a862005-12-18 01:27:35 +0000944- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000945 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000946 is now displayed in interactive prompt banner.
947
Georg Brandlfa166682005-12-17 21:45:17 +0000948- Implementation of PEP 341 - Unification of try/except and try/finally.
949 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000950 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000951
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000952- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
953 now encodes backslash correctly.
954
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000955- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
956
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000957- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000958 and long longs.
959
Neal Norwitz67715f02005-11-09 06:59:35 +0000960- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000961 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000962 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000963
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000964- Replaced most Unicode charmap codecs with new ones using the
965 new Unicode translate string feature in the builtin charmap
966 codec; the codecs were created from the mapping tables available
967 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
968 encodings now include a mapping for the Apple logo)
969
Tim Peterse3547fd2005-12-16 23:13:57 +0000970- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000971
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000972- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000973
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000974- A new AST parser implementation was completed. The abstract
975 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000976 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000977
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000978- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000979 The following code now raises a SyntaxError: foo(a = i for i in range(10))
980
Neal Norwitz708e51a2005-10-03 04:48:15 +0000981- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
982
Neal Norwitz11bd1192005-10-03 00:54:56 +0000983- SF Bug #887946: fix segfault when redirecting stdin from a directory.
984 Provide a warning when a directory is passed on the command line.
985
Neal Norwitz40d37812005-10-02 01:48:49 +0000986- Fix segfault with invalid coding.
987
988- SF bug #772896: unknown encoding results in MemoryError.
989
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000990- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000991 supported a __len__() method which evaluated to False when the iterator
992 was empty.
993
Guido van Rossum630db602005-09-20 18:49:54 +0000994- On 64-bit platforms, when __len__() returns a value that cannot be
995 represented as a C int, raise OverflowError.
996
Skip Montanarof8948ca2005-09-19 03:54:46 +0000997- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000998 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000999
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001000- SF bug #893549: parsing keyword arguments was broken with a few format
1001 codes.
1002
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001003- Changes donated by Elemental Security to make it work on AIX 5.3
1004 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1005 bug #105470: test_pwd fails on 64bit system (Opteron).
1006
Guido van Rossum539c6622005-09-14 17:49:54 +00001007- Changes donated by Elemental Security to make it work on HP-UX 11 on
1008 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1009
Georg Brandl4550b8d2005-08-26 06:43:52 +00001010- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001011 (fixes bug #1119418).
1012
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001013- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1014
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001015- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1016 exceptions that cause a function to exit.
1017
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001018- The implementation of set() and frozenset() was revised to use its
1019 own internal data structure. Memory consumption is reduced by 1/3
1020 and there are modest speed-ups as well. The API is unchanged.
1021
Tim Petersde7990b2005-07-17 23:45:23 +00001022- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1023
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001024- SF bug #1229429: PyObject_CallMethod failed to decrement some
1025 reference counts in some error exit cases.
1026
Tim Petersecc6e6a2005-07-10 22:30:55 +00001027- SF bug #1185883: Python's small-object memory allocator took over
1028 a block managed by the platform C library whenever a realloc specified
1029 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001030 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001031 portable way to copy data from the C-managed block into Python's
1032 small-object space without risking a memory fault. Python's small-object
1033 realloc now leaves such blocks under the control of the platform C
1034 realloc.
1035
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001036- SF bug #1232517: An overflow error was not detected properly when
1037 attempting to convert a large float to an int in os.utime().
1038
Raymond Hettinger3296e692005-06-29 23:29:56 +00001039- SF bug #1224347: hex longs now print with lowercase letters just
1040 like their int counterparts.
1041
Michael W. Hudson188d4362005-06-20 16:52:57 +00001042- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1043 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1044 interpreter states; back out that fix and do a better job (see
1045 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1046 for a longer write-up of the problem).
1047
Michael W. Hudsondf888462005-06-03 14:41:55 +00001048- SF patch #1180995: marshal now uses a binary format by default when
1049 serializing floats.
1050
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001051- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1052 the routines that promise to produce IEEE 754 binary representations
1053 of floats now simply copy bytes around.
1054
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001055- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1056 278.
1057
Brett Cannonc3647ac2005-04-26 03:45:26 +00001058- patch #1109424: int, long, float, complex, and unicode now check for the
1059 proper magic slot for type conversions when subclassed. Previously the
1060 magic slot was ignored during conversion. Semantics now match the way
1061 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001062 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001063 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001064 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001065
Barry Warsawc8d907c2005-04-19 23:43:40 +00001066- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1067 NULL, now raise an AttributeError when attempting to set or delete the
1068 attribute. Previously a TypeError was raised, but this was inconsistent
1069 with the equivalent pure-Python implementation.
1070
Michael W. Hudson774479c2005-04-18 08:46:17 +00001071- It is now safe to call PyGILState_Release() before
1072 PyEval_InitThreads() (note that if there is reason to believe there
1073 are multiple threads around you still must call PyEval_InitThreads()
1074 before using the Python API; this fix is for extension modules that
1075 have no way of knowing if Python is multi-threaded yet).
1076
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001077- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1078 disabled caused a crash.
1079
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001080- Bug #1165306: instancemethod_new allowed the creation of a method
1081 with im_class == im_self == NULL, which caused a crash when called.
1082
Tim Petersecc6e6a2005-07-10 22:30:55 +00001083- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001084 fixes the crash seen in bug #1165761
1085
Raymond Hettinger96229b12005-03-11 06:49:40 +00001086- Added two new builtins, any() and all().
1087
Brett Cannon409d8f22005-03-05 06:47:57 +00001088- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001089 (e.g., ``class C(): pass`` is no longer a syntax error).
1090 Patch #1176012 added support to the 'parser' module and 'compiler' package
1091 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001092
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001093- Patch #1115086: Support PY_LONGLONG in structmember.
1094
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001095- Bug #1155938: new style classes did not check that __init__() was
1096 returning None.
1097
Tim Petersecc6e6a2005-07-10 22:30:55 +00001098- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001099 ('\') with a specific error message.
1100
Martin v. Löwisff232d72005-03-03 09:24:38 +00001101- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1102
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001103- Bug #1124295: the __name__ attribute of file objects was
1104 inadvertently made inaccessible in restricted mode.
1105
Tim Petersecc6e6a2005-07-10 22:30:55 +00001106- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001107 an ferror() call.
1108
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001109- min() and max() now support key= arguments with the same meaning as in
1110 list.sort().
1111
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001112- The peephole optimizer now performs simple constant folding in expressions:
1113 (2+3) --> (5).
1114
Raymond Hettingera422c342005-01-11 03:03:27 +00001115- set and frozenset objects can now be marshalled. SF #1098985.
1116
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001117- Bug #1077106: Poor argument checking could cause memory corruption
1118 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001119
Jeremy Hyltonab630502005-02-04 18:44:06 +00001120- The parser did not complain about future statements in illegal
1121 positions. It once again reports a syntax error if a future
1122 statement occurs after anything other than a doc string.
1123
Neil Schemenauercf52c072005-08-12 17:34:58 +00001124- Change the %s format specifier for str objects so that it returns a
1125 unicode instance if the argument is not an instance of basestring and
1126 calling __str__ on the argument returns a unicode instance.
1127
Tim Petersf4e69282006-02-27 17:15:31 +00001128- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1129 current thread state when the auto-GIL-state machinery knows about
1130 it (since the thread state is being deleted, continuing to remember it
1131 can't help, but can hurt if another thread happens to get created with
1132 the same thread id).
1133
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001134Extension Modules
1135-----------------
1136
Georg Brandl43f08a82006-03-31 18:01:16 +00001137- Patch #1380952: fix SSL objects timing out on consecutive read()s
1138
Neal Norwitz05a45592006-03-20 06:30:08 +00001139- Patch #1309579: wait3 and wait4 were added to the posix module.
1140
Anthony Baxterfa869072006-03-20 05:21:58 +00001141- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1142 In addition, the existing ulaw code was updated.
1143
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001144- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001145 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001146
Neal Norwitz10be10c2006-03-16 06:50:13 +00001147- Everything under lib-old was removed. This includes the following modules:
1148 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001149 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001150 util, whatsound, whrandom, zmod
1151
1152- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1153
1154- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001155 is deprecated. The undocumented re.engine variable no longer exists.
1156
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001157- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1158 SS2 (single-shift 2) escape sequences correctly.
1159
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001160- The unicodedata module was updated to the 4.1 version of the Unicode
1161 database. The 3.2 version is still available as unicodedata.db_3_2_0
1162 for applications that require this specific version (such as IDNA).
1163
Neal Norwitzb62c4332006-03-04 18:35:47 +00001164- The timing module is no longer built by default. It was deprecated
1165 in PEP 4 in Python 2.0 or earlier.
1166
Guido van Rossum1968ad32006-02-25 22:38:04 +00001167- Patch 1433928: Added a new type, defaultdict, to the collections module.
1168 This uses the new __missing__ hook behavior added to dict (see above).
1169
Georg Brandldbd83392006-02-20 09:42:33 +00001170- Bug #854823: socketmodule now builds on Sun platforms even when
1171 INET_ADDRSTRLEN is not defined.
1172
Georg Brandlf4f44152006-02-18 22:29:33 +00001173- Patch #1393157: os.startfile() now has an optional argument to specify
1174 a "command verb" to invoke on the file.
1175
Neal Norwitz082b2df2006-02-07 07:04:46 +00001176- Bug #876637, prevent stack corruption when socket descriptor
1177 is larger than FD_SETSIZE.
1178
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001179- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1180 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1181 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1182
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001183- Patch #1422385: The nis module now supports access to domains other
1184 than the system default domain.
1185
Martin v. Löwis14694662006-02-03 12:54:16 +00001186- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1187 are reported, the limit on path name lengths is removed, and stat reports

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001324- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1325 been renamed to have only a single underscore prefix. This was done to
1326 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001327
Nick Coghlan43832302006-04-23 17:04:07 +00001328- PEP 338: new module runpy defines a run_module function to support
1329 executing modules which provide access to source code or a code object
1330 via the PEP 302 import mechanisms.
1331
Anthony Baxter93f5b932006-04-03 08:05:07 +00001332- The email module's parsedate_tz function now sets the daylight savings

1340 in attribute values.
1341
Anthony Baxterc51ee692006-04-01 00:57:31 +00001342- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001343 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001344 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001345 module will not be built.
1346
Tim Petersc17976e2006-04-01 00:26:53 +00001347- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1348 aren't officially supported here, and trying to use them will probably
1349 raise an exception some day. But dicts have been allowed, and "mostly
1350 worked", so support for them won't go away without warning.
1351
Georg Brandl338ef7d2006-03-31 18:42:16 +00001352- Bug #1445068: getpass.getpass() can now be given an explicit stream

1370
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001371- email 4.0 package now integrated. This is largely the same as the email 3.0
1372 package that was included in Python 2.3, except that PEP 8 module names are
1373 now used (e.g. mail.message instead of email.Message). The MIME classes
1374 have been moved to a subpackage (e.g. email.mime.text instead of
1375 email.MIMEText). The old names are still supported for now. Several
1376 deprecated Message methods have been removed and lots of bugs have been
1377 fixed. More details can be found in the email package documentation.
1378
Walter Dörwald40108c92006-03-27 08:15:44 +00001379- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1380 (a subclass of tuple) that provides incremental decoders and encoders
1381 (a way to use stateful codecs without the stream API). Python functions
1382 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1383 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1384 have been added.

1387 a ValueError instead of a StopIteration now (like file and cString.String do).
1388 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1389 called before (like file and StringIO.StringIO do).

1457
Neal Norwitz338e7862005-12-23 21:27:46 +00001458- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1459 LoadError as documented, instead of IOError. For compatibility,
1460 LoadError subclasses IOError.
1461
Brett Cannon3cbd0382005-12-16 22:49:23 +00001462- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001463 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1464 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1465 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1466 Ronald L. Rivest offered this advice for Python:
1467
1468 "The consensus of researchers in this area (at least as
1469 expressed at the NIST Hash Function Workshop 10/31/05),
1470 is that SHA-256 is a good choice for the time being, but
1471 that research should continue, and other alternatives may
1472 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001473
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001474- Added a subset of Fredrik Lundh's ElementTree package. Available

1516
Georg Brandl532efab2005-08-24 22:34:21 +00001517- Patch #848017: Make Cookie more RFC-compliant. Use CRLF as default output
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001518 separator and do not output trailing semicolon.
Georg Brandl532efab2005-08-24 22:34:21 +00001519
Georg Brandlb9256022005-08-24 18:46:39 +00001520- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1521 ContentTooShortException, when the actually downloaded size does not
1522 match the Content-Length header.
1523

1527 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001528 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001529

1542 docstrings to either "article number" or "message id".
1543
Georg Brandla4a8b822005-07-15 09:13:21 +00001544- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1545 parameter, but uses the usual "kwargs=None".
1546
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001547- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001548 Patch #1209527 (Contributed by Connelly).
1549

1551 to W3C name (404 -> 'Not Found'). RFE #1216944.
1552
Georg Brandl9e43acf2005-07-04 17:16:07 +00001553- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1554 as this can cause problems with apps closing all file descriptors.

1565
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001566- The tokenize module now detects and reports indentation errors.
1567 Bug #1224621.
1568
Raymond Hettinger68c04532005-06-10 11:05:19 +00001569- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001570 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001571 the generate_tokens() function now accepts a callable argument that
1572 terminates by raising StopIteration.
1573
Georg Brandl9166e1a2005-06-04 09:20:03 +00001574- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1578
Skip Montanaro174dd222005-05-14 20:54:16 +00001579- Patch #1120353: The xmlrpclib module provides better, more transparent,
1580 support for datetime.{datetime,date,time} objects. With use_datetime set
1581 to True, applications shouldn't have to fiddle with the DateTime wrapper
1582 class at all.
1583
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001584- distutils.commands.upload was added to support uploading distribution

1588 them to PyPI.
1589
Raymond Hettinger267b8682005-03-27 10:47:39 +00001590- decimal operator and comparison methods now return NotImplemented
1591 instead of raising a TypeError when interacting with other types. This
1592 allows other classes to implement __radd__ style methods and have them
1593 work as expected.
1594
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001595- Bug #1163325: Decimal infinities failed to hash. Attempting to
1596 hash a NaN raised an InvalidOperation instead of a TypeError.
1597
Tim Petersecc6e6a2005-07-10 22:30:55 +00001598- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001599 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1600

1611
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001612- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1613

1632
Guido van Rossumd0641422005-02-03 15:01:24 +00001633- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1634 disables recursive traversal through instance attributes, which can
1635 be exploited in various ways.
1636
Tim Peterse3547fd2005-12-16 23:13:57 +00001637- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001638 flags on the HTTP listening socket.
1639
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001640- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1641 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1642
Tim Peterse3547fd2005-12-16 23:13:57 +00001643- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001644 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1645
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001646- Bug #1110478: Revert os.environ.update to do putenv again.
1647
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001648- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1649
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001650- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1651
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001652- Enhancements to the csv module:
1653
1654 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001655 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001656 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001657 + Dialect parameter parsing has been re-implemented to improve error
1658 reporting.
1659 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1660 dictates.
1661 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001662 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001663 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001664 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1665 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001666 + reader now allows \r characters to be quoted (previously it only allowed
1667 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001668 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001669 + Dialect classes passed to the module are no longer instantiated by
1670 the module before being parsed (the former validation scheme required
1671 this, but the mechanism was unreliable).
1672 + The dialect registry now contains instances of the internal
1673 C-coded dialect type, rather than references to python objects.
1674 + the internal c-coded dialect type is now immutable.
1675 + register_dialect now accepts the same keyword dialect specifications
1676 as the reader and writer, allowing the user to register dialects
1677 without first creating a dialect class.
1678 + a configurable limit to the size of parsed fields has been added -
1679 previously, an unmatched quote character could result in the entire
1680 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001681 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001682 the parser field size limit (returning the former limit). The initial
1683 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001684 + A line_num attribute has been added to the reader object, which tracks
1685 the number of lines read from the source iterator. This is not
1686 the same as the number of records returned, as records can span
1687 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001688 + reader and writer objects were not being registered with the cyclic-GC.
1689 This has been fixed.
1690
Brett Cannone6539c42005-01-08 02:43:53 +00001691- _DummyThread objects in the threading module now delete self.__block that is
1692 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1693 lock primitives tend to be limited in number and thus should not be wasted on
1694 a _DummyThread object. Fixes bug #1089632.
1695
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001696- The imghdr module now detects Exif files.
1697
Raymond Hettinger6065d322004-12-20 23:51:53 +00001698- StringIO.truncate() now correctly adjusts the size attribute.
1699 (Bug #951915).
1700
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001701- locale.py now uses an updated locale alias table (built using
1702 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1703 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001704 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001705
Raymond Hettinger3557f422004-12-07 12:02:02 +00001706- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1707
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001708- the pickle module no longer accepts the deprecated None option in the
1709 args tuple returned by __reduce__().
1710
Brett Cannon84667c02004-12-07 03:25:18 +00001711- optparse now optionally imports gettext. This allows its use in setup.py.
1712
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001713- the pickle module no longer uses the deprecated bin parameter.
1714

1720
Raymond Hettinger664347b2004-12-04 21:21:53 +00001721- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1722 extended or overridden by subclasses. Formerly, the subclassed method would
1723 be ignored by the rest of the module. (Bug #1078905).
1724
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001725- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001726 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001727
Walter Dörwald36733692004-12-22 12:50:50 +00001728- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1729 once when a size argument is given. This prevents a buffer overflow in the
1730 tokenizer with very long source lines.
1731
Barry Warsaw538561e2006-01-01 21:48:54 +00001732- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1733 immediately after creating the object, without any intervening
1734 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001735
Skip Montanaro05885812005-01-16 20:48:27 +00001736- The reconvert.quote function can now emit triple-quoted strings. The
1737 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001738
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001739- ``UserString.MutableString`` now supports negative indices in
1740 ``__setitem__`` and ``__delitem__``
1741
Greg Ward40407942005-03-05 02:53:17 +00001742- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1743 correctly.
1744
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001745- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1746 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1747 character even if the user has passed a size parameter to get a proper
1748 line ending. Remove the special handling of a "\r\n" that has been split
1749 between two lines.
1750
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001751- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1752 about illegal code points. The codec now supports PEP 293 style error
1753 handlers.
1754
Walter Dörwald78a78b02005-09-01 12:04:29 +00001755- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001756 from the input stream, so that the output is a byte string in the correct
1757 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001758
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001759- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1760 considering it exactly like a '*'.
1761
Walter Dörwald007f8df2005-10-09 19:42:27 +00001762- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1763 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001764
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001765- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1766
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001767- Patch #1413711: Certain patterns of differences were making difflib
1768 touch the recursion limit.
1769
Walter Dörwald58917a62006-03-31 15:26:22 +00001770- Bug #947906: An object oriented interface has been added to the calendar
1771 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001772 called as a script (e.g. via ``python -mcalendar``). Localized month and
1773 weekday names can be ouput (even if an exotic encoding is used) using
1774 special classes that use unicode.

1777-----
1778
Neal Norwitz602d3392006-03-31 08:21:40 +00001779- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1780 by using -mieee gcc option.
1781

1783
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001784- Build support for Win64-AMD64 was added.
1785
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001786- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1787
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001788- Patch #881820: look for openpty and forkpty also in libbsd.
1789
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001790- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1791 The zlib module is now builtin on Windows.
1792
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001793- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1794
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001795- Bug #1189330: configure did not correctly determine the necessary
1796 value of LINKCC if python was built with GCC 4.0.
1797
Trent Mick8321b422005-07-26 02:29:21 +00001798- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1799 vulnerability in zlib 1.2.1 and 1.2.2.
1800
Brett Cannon08cd5982005-04-24 22:26:38 +00001801- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1802 flags that change binary compatibility. Changes were also made to
1803 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001804 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001805
Bob Ippolitoed233462005-03-29 13:47:59 +00001806- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1807 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1808 no longer exists). This configure patch makes things right.
1809
Martin v. Löwise2713be2005-03-08 15:03:08 +00001810- Bug #1158607: Build with --disable-unicode again.
1811
Brett Cannon46d96232005-02-16 00:07:19 +00001812- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1813 defined. Discovered as a result of not being able to build on OS X.
1814
Brett Cannon516592f2004-12-07 00:42:59 +00001815- setup.py now uses the directories specified in LDFLAGS using the -L option
1816 and in CPPFLAGS using the -I option for adding library and include
1817 directories, respectively, for compiling extension modules against. This has
1818 led to the core being compiled using the values in CPPFLAGS. It also removes
1819 the need for the special-casing of both DarwinPorts and Fink for darwin since
1820 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1821 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1822 Fink, ``-I/opt/local/include`` for DarwinPorts).
1823
Brett Cannon43802422005-02-10 20:48:03 +00001824- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1825 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1826 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1827 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001829C API
1830-----
1831
Tim Petersc9d78aa2006-03-26 23:27:58 +00001832- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1833 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1834 is obtained via the ``PyObject_`` family, it must be released via the
1835 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1836 always been officially true, but when Python's small-object allocator was
1837 introduced, an attempt was made to cater to a few extension modules
1838 discovered at the time that obtained memory via ``PyObject_New`` but
1839 released it via ``PyMem_DEL``. It's years later, and if such code still
1840 exists it will fail now (probably with segfaults, but calling wrong
1841 low-level memory management functions can yield many symptoms).
1842
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001843- Added a C API for set and frozenset objects.
1844

1846
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001847- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1848 mapping argument now. This string is used as a mapping table. Byte values
1849 greater than the length of the string and 0xFFFE are treated as undefined
1850 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001856- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001857
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001858- Patch #1276356: New resource "urlfetch" is implemented. This enables
1859 even impatient people to run tests that require remote files.
