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
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000015- Bug #1515471: string.replace() accepts character buffers again.
16
Neal Norwitz07aadb12006-07-30 06:55:48 +000017- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
18 This provides the proper warning for struct.pack().
19 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
20
Neal Norwitz0d62a062006-07-30 06:53:31 +000021- Patch #1531113: Fix augmented assignment with yield expressions.
22 Also fix a SystemError when trying to assign to yield expressions.
23
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000024- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
25 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
26 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
27 excessive filesystem operations during imports.
28
Tim Petersbc24eee2006-07-27 01:14:53 +000029- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
30 operations on signed longs that are formally undefined by C.
31 Unfortunately, at least one compiler now cares about that, so complicated
32 the code to make that compiler happy again.
33
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000034- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
35
Martin v. Löwisd22968a2006-07-24 11:54:53 +000036- Patch #1232023: Stop including current directory in search
37 path on Windows.
38
Neal Norwitze1fdb322006-07-21 05:32:28 +000039- Fix some potential crashes found with failmalloc.
40
Neal Norwitze7563102006-07-17 01:00:16 +000041- Fix warnings reported by Klocwork's static analysis tool.
42
Neal Norwitz84be93b2006-07-16 01:50:38 +000043- Bug #1512814, Fix incorrect lineno's when code within a function
44 had more than 255 blank lines.
45
Georg Brandl9dceedb2006-07-12 15:31:17 +000046- Patch #1521179: Python now accepts the standard options ``--help`` and
47 ``--version`` as well as ``/?`` on Windows.
48
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000049- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000050 again. Fixing this problem required changing the .pyc magic number.
51 This means that .pyc files generated before 2.5c1 will be regenerated.
52
Tim Peters112aad32006-07-19 00:03:19 +000053- Bug #1524317: Compiling Python ``--without-threads`` failed.
54 The Python core compiles again then, and, in a build without threads, the
55 new ``sys._current_frames()`` returns a dictionary with one entry,
56 mapping the faux "thread id" 0 to the current frame.
57
Ronald Oussoren3075e162006-07-25 20:28:55 +000058- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000059
Ronald Oussoren3075e162006-07-25 20:28:55 +000060
Neal Norwitza1f10902006-07-12 07:28:29 +000061Library
62-------
63
Martin v. Löwis4e678382006-07-30 13:00:31 +000064- Bug #1525866: Don't copy directory stat times in
65 shutil.copytree on Windows
66
Georg Brandle34ac7c2006-07-30 11:07:23 +000067- Bug #1002398: The documentation for os.path.sameopenfile now correctly
68 refers to file descriptors, not file objects.
69
Fred Drakefbdeaad2006-07-29 16:56:15 +000070- Rename of the xml package to xmlcore, and the import hackery done to
71 make it appear at both names, has been removed. Bug #1511497,
72 #1513611, and probably others.
73
Georg Brandledd9b0d2006-07-29 09:33:26 +000074- Bug #1441397: The compiler module now recognizes module and function
75 docstrings correctly as it did in Python 2.4.
76
Tim Peters6f681472006-07-27 23:44:37 +000077- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
78 lost that tests are sorted by name before being run. This rarely
79 matters for well-written tests, but can create baffling symptoms if
80 side effects from one test to the next affect outcomes. ``DocTestFinder``
81 has been changed to sort the list of tests it returns.
82
Martin v. Löwis1f30c372006-07-30 13:14:05 +000083- The distutils version has been changed to 2.5.0, and are now kept
84 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +000085
Martin v. Löwis9298eff2006-07-26 12:12:56 +000086- Bug #978833: Really close underlying socket in _socketobject.close.
87
Georg Brandl0619a322006-07-26 07:40:17 +000088- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
89 with title().
90
Georg Brandlcf0c1722006-07-26 07:23:32 +000091- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
92 to recursive calls and call it with the failing package name.
93
Martin v. Löwis0b483032006-07-25 09:53:12 +000094- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
95
Georg Brandlc13c34c2006-07-24 14:09:56 +000096- Patch #1515343: Fix printing of deprecated string exceptions with a
97 value in the traceback module.
98
Greg Ward48fae7a2006-07-23 16:05:51 +000099- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
100
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000101- Patch #1524429: Use repr() instead of backticks in Tkinter again.
102
Brett Cannoncaebe222006-07-18 04:41:36 +0000103- Bug #1520914: Change time.strftime() to accept a zero for any position in its
104 argument tuple. For arguments where zero is illegal, the value is forced to
105 the minimum value that is correct. This is to support an undocumented but
106 common way people used to fill in inconsequential information in the time
107 tuple pre-2.4.
108
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000109- Patch #1220874: Update the binhex module for Mach-O.
110
Barry Warsawb110bad2006-07-21 14:51:07 +0000111- The email package has improved RFC 2231 support, specifically for
112 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
113 (name*0=<blah>) parameter continuations. This may change the types of
114 values returned from email.message.Message.get_param() and friends.
115 Specifically in some cases where non-encoded continuations were used,
116 get_param() used to return a 3-tuple of (None, None, string) whereas now it
117 will just return the string (since non-encoded continuations don't have
118 charset and language parts).
119
120 Also, whereas % values were decoded in all parameter continuations, they are
121 now only decoded in encoded parameter parts.
122
Ronald Oussoren3075e162006-07-25 20:28:55 +0000123- Bug #1517990: IDLE keybindings on MacOS X now work correctly
124
125- Bug #1517996: IDLE now longer shows the default Tk menu when a
126 path browser, class browser or debugger is the frontmost window on MacOS X
127
Barry Warsaw00decd72006-07-27 23:43:15 +0000128- Patch #1520294: Support for getset and member descriptors in types.py,
129 inspect.py, and pydoc.py. Specifically, this allows for querying the type
130 of an object against these built-in types and more importantly, for getting
131 their docstrings printed in the interactive interpreter's help() function.
132
Ronald Oussoren3075e162006-07-25 20:28:55 +0000133
Neal Norwitza1f10902006-07-12 07:28:29 +0000134Extension Modules
135-----------------
136
Thomas Heller1393d6a2006-07-28 21:43:20 +0000137- Patch #1529514: The _ctypes extension is now compiled on more
138 openbsd target platforms.
139
Tim Peters9cab5932006-07-28 00:30:00 +0000140- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
141 a memory leak, affecting pickles and deep copies.
142
Tim Petersbc24eee2006-07-27 01:14:53 +0000143- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000144 Paul Eggert.
145

Thomas Hellerce049a02006-07-14 17:51:14 +0000148- Patch #1521817: Index range checking on ctypes arrays containing
149 exactly one element enabled again. This allows iterating over these
150 arrays, without the need to check the array size before.
151
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000152- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000153 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000154 /dev/null in certain cases; this is now fixed.
155
Thomas Heller47d7a062006-07-12 08:43:47 +0000156- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
157 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000158
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000159- Because of a misspelled preprocessor symbol, ctypes was always
160 compiled without thread support; this is now fixed.
161
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000162- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
163 methods now allow their database parameter to be None as the
164 sleepycat API allows.
165
Matt Flemingec926502006-07-28 11:27:27 +0000166- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
167 bluetooth API compared with Linux and FreeBSD.
168
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000169Tests
170-----
171
172- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
173 how long the test file should take to play. Now accepts taking 2.93 secs
174 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
175
Georg Brandl4793aa32006-07-28 18:31:39 +0000176- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
177 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
178 run via ``regrtest.py``. Now they do.

186Core and builtins
187-----------------
188
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000189- Bug #1441486: The literal representation of -(sys.maxint - 1)
190 again evaluates to a int object, not a long.
191
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000192- Bug #1501934: The scope of global variables that are locally assigned
193 using augmented assignment is now correctly determined.
194
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000195- Bug #927248: Recursive method-wrapper objects can now safely
196 be released.
197
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000198- Bug #1417699: Reject locale-specific decimal point in float()
199 and atof().
200
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000201- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
202 omit a default "error" argument for NULL pointer. This allows
203 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000204
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000205- Bug #1519018: 'as' is now validated properly in import statements.
206
Neal Norwitz28746ab2006-07-09 22:14:42 +0000207- On 64 bit systems, int literals that use less than 64 bits are
208 now ints rather than longs.
209
Neal Norwitzed657552006-07-10 00:04:44 +0000210- Bug #1512814, Fix incorrect lineno's when code at module scope
211 started after line 256.
212
Tim Peters32a83612006-07-10 21:08:24 +0000213- New function ``sys._current_frames()`` returns a dict mapping thread
214 id to topmost thread stack frame. This is for expert use, and is
215 especially useful for debugging application deadlocks. The functionality
216 was previously available in Fazal Majid's ``threadframe`` extension
217 module, but it wasn't possible to do this in a wholly threadsafe way from
218 an extension.
219

224 VS 2003.
225
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000226- Patch #1519566: Update turtle demo, make begin_fill idempotent.
227
Tim Peters32a83612006-07-10 21:08:24 +0000228- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000229 environment variable to be set in order to the SDK environment
230 for finding the compiler, include files, etc.

235
Thomas Woutersadd19112006-07-05 11:03:49 +0000236- string.Template() now correctly handles tuple-values. Previously,
237 multi-value tuples would raise an exception and single-value tuples would
238 be treated as the value they contain, instead.
239
Martin v. Löwisede77f52006-07-03 13:01:35 +0000240- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

248
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000249- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000250 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000251

263
Georg Brandl1be63af2006-06-28 20:23:25 +0000264- Fix a bug in the turtle module's end_fill function.
265
Brett Cannon53ab5b72006-06-22 16:49:14 +0000266- Bug #1510580: The 'warnings' module improperly required that a Warning
267 category be either a types.ClassType and a subclass of Warning. The proper
268 check is just that it is a subclass with Warning as the documentation states.
269
Georg Brandlad29e632006-06-21 17:45:17 +0000270- The compiler module now correctly compiles the new try-except-finally
271 statement (bug #1509132).
272
Neal Norwitz60373cd2006-06-22 06:30:50 +0000273- The wsgiref package is now installed properly on Unix.
274
Vinay Sajip28e57612006-07-01 10:45:20 +0000275- A bug was fixed in logging.config.fileConfig() which caused a crash on
276 shutdown when fileConfig() was called multiple times.
277
Gerhard Häring762fbd32006-07-02 17:48:30 +0000278- The sqlite3 module did cut off data from the SQLite database at the first
279 null character before sending it to a custom converter. This has been fixed
280 now.
281
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000282Extension Modules
283-----------------
284
Tim Peters112aad32006-07-19 00:03:19 +0000285- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
286 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
287 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000288
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000289- Assigning None to pointer type fields in ctypes structures possible
290 overwrote the wrong fields, this is fixed now.
291
292- Fixed a segfault in _ctypes when ctypes.wintypes were imported
293 on non-Windows platforms.
294
295- Bug #1518190: The ctypes.c_void_p constructor now accepts any
296 integer or long, without range checking.
297
298- Patch #1517790: It is now possible to use custom objects in the ctypes
299 foreign function argtypes sequence as long as they provide a from_param
300 method, no longer is it required that the object is a ctypes type.
301
302- The '_ctypes' extension module now works when Python is configured
303 with the --without-threads option.
304
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000305- Bug #1513646: os.access on Windows now correctly determines write
306 access, again.

Martin v. Löwisd73168d2006-07-14 09:58:55 +0000319- Automate Windows build process for the Win64 SSL module.
320
Tim Peters32a83612006-07-10 21:08:24 +0000321- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000322 Previously, the slight difference could cause compilation errors of the
323 'zlib' module on systems with more than one version of zlib.
324
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000325- The MSI compileall step was fixed to also support a TARGETDIR
326 with spaces in it.
327
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000328- Bug #1517388: sqlite3.dll is now installed on Windows independent
329 of Tcl/Tk.
330
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000331- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old

Anthony Baxter51bcb682006-04-05 14:51:42 +0000352
Anthony Baxterd1136802006-06-19 12:04:15 +0000353*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000354
355Core and builtins
356-----------------
357
Georg Brandla56b9152006-06-19 06:35:54 +0000358- Patch #1507676: Error messages returned by invalid abstract object operations
359 (such as iterating over an integer) have been improved and now include the
360 type of the offending object to help with debugging.
361
Brett Cannonea3912b2006-06-13 21:46:41 +0000362- Bug #992017: A classic class that defined a __coerce__() method that returned
363 its arguments swapped would infinitely recurse and segfault the interpreter.
364
Neal Norwitz909eb122006-06-12 02:13:21 +0000365- Fix the socket tests so they can be run concurrently.
366
Neal Norwitzb9845e72006-06-12 02:11:18 +0000367- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000368 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000369
Brett Cannon22565aa2006-06-09 22:31:23 +0000370- Bug #532646: object.__call__() will continue looking for the __call__
371 attribute on objects until one without one is found. This leads to recursion
372 when you take a class and set its __call__ attribute to an instance of the
373 class. Originally fixed for classic classes, but this fix is for new-style.
374 Removes the infinite_rec_3 crasher.
375
Georg Brandl24250812006-06-09 18:45:48 +0000376- The string and unicode methods startswith() and endswith() now accept
377 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
378
Brett Cannonde3b0522006-06-08 17:00:45 +0000379- Buffer objects, at the C level, never used the char buffer
380 implementation even when the char buffer for the wrapped object was
381 explicitly requested (originally returned the read or write buffer).
382 Now a TypeError is raised if the char buffer is not present but is
383 requested.
384
Georg Brandlddbaa662006-06-04 21:56:52 +0000385- Patch #1346214: Statements like "if 0: suite" are now again optimized
386 away like they were in Python 2.4.
387
Georg Brandlb7c8f542006-05-27 12:30:25 +0000388- Builtin exceptions are now full-blown new-style classes instead of
389 instances pretending to be classes, which speeds up exception handling
390 by about 80% in comparison to 2.5a2.
391
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000392- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
393 Unicode 4.1.
394
Georg Brandlf4ef1162006-05-26 18:03:31 +0000395- Patch #921466: sys.path_importer_cache is now used to cache valid and
396 invalid file paths for the built-in import machinery which leads to
397 fewer open calls on startup.
398
Tim Peters696cf432006-05-24 21:10:40 +0000399- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
400 of-2 bases. The largest speedup is for inputs with about 1000 decimal
401 digits. Conversion from non-power-of-2 bases remains quadratic-time in
402 the number of input digits (it was and remains linear-time for bases
403 2, 4, 8, 16 and 32).
404
Tim Petersb713ec22006-05-23 18:45:30 +0000405- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
406 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
407 an integer close to ``sys.maxint``. This was repaired by patch
408 #1335972, which also gives a nice speedup.
409
Richard Jonescebbefc2006-05-23 18:28:17 +0000410- Patch #1337051: reduced size of frame objects.
411
412- PyErr_NewException now accepts a tuple of base classes as its
413 "base" parameter.
414
Richard Jones7c88dcc2006-05-23 10:37:38 +0000415- Patch #876206: function call speedup by retaining allocated frame
416 objects.
417
Georg Brandl7b90e162006-05-18 07:01:27 +0000418- Bug #1462152: file() now checks more thoroughly for invalid mode
419 strings and removes a possible "U" before passing the mode to the
420 C library function.
421
Neal Norwitz1004a532006-05-15 07:17:23 +0000422- Patch #1488312, Fix memory alignment problem on SPARC in unicode
423
Neal Norwitz373f0a72006-05-15 07:04:36 +0000424- Bug #1487966: Fix SystemError with conditional expression in assignment
425
Martin v. Löwis879768d2006-05-11 13:28:43 +0000426- WindowsError now has two error code attributes: errno, which carries
427 the error values from errno.h, and winerror, which carries the error
428 values from winerror.h. Previous versions put the winerror.h values
429 (from GetLastError()) into the errno attribute.
430
Martin v. Löwis77736712006-05-04 05:51:03 +0000431- Patch #1475845: Raise IndentationError for unexpected indent.
432
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000433- Patch #1479181: split open() and file() from being aliases for each other.
434
Tim Peters44bd9862006-06-01 13:49:23 +0000435- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
436 methods were always silently ignored by dictionaries when comparing keys.
437 They are now passed through (except when using the C API function
438 ``PyDict_GetItem()``, whose semantics did not change).
439
440- Bug #1456209: In some obscure cases it was possible for a class with a
441 custom ``__eq__()`` method to confuse dict internals when class instances
442 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
443 No, you don't have any code that did this ;-)

449
450- Patch #1462338: Upgrade pyexpat to expat 2.0.0
451
Brett Cannon6ee7d012006-06-08 16:23:04 +0000452- Change binascii.hexlify to accept a read-only buffer instead of only a char
453 buffer and actually follow its documentation.
454
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000455- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
456
Nick Coghlanc649ec52006-05-29 12:43:05 +0000457- Patch #1478788 (modified version): The functional extension module has
458 been renamed to _functools and a functools Python wrapper module added.
459 This provides a home for additional function related utilities that are
460 not specifically about functional programming. See PEP 309.
461
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000462- Patch #1493701: performance enhancements for struct module.
463
Georg Brandl378d5922006-05-17 14:26:50 +0000464- Patch #1490224: time.altzone is now set correctly on Cygwin.
465
Georg Brandl8d3342b2006-05-16 07:38:27 +0000466- Patch #1435422: zlib's compress and decompress objects now have a
467 copy() method.
468
Andrew MacIntyre92913322006-06-13 15:04:24 +0000469- Patch #1454481: thread stack size is now tunable at runtime for thread
470 enabled builds on Windows and systems with Posix threads support.
471
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000472- On Win32, os.listdir now supports arbitrarily-long Unicode path names
473 (up to the system limit of 32K characters).
474
475- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
476 As a result, these functions now raise WindowsError instead of OSError.
477
Tim Peters7a822da2006-05-25 21:50:17 +0000478- ``time.clock()`` on Win64 should use the high-performance Windows
479 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
480 Windows platforms).
481
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000482- Calling Tk_Init twice is refused if the first call failed as that
483 may deadlock.
484
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000485- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
486 accept it without potentially using an uninitialized pointer.
487
488- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
489 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
490 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000491
Gregory P. Smith372b5832006-06-05 18:48:21 +0000492- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000493 [pybsddb project SF patch number 1466734]
494
Gregory P. Smith372b5832006-06-05 18:48:21 +0000495- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
496 parameter is supplied. [SF pybsddb bug #1477863]
497
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000498- bsddb: the __len__ method of a DB object has been fixed to return correct
499 results. It could previously incorrectly return 0 in some cases.
500 Fixes SF bug 1493322 (pybsddb bug 1184012).
501
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000502- bsddb: the bsddb.dbtables Modify method now raises the proper error and
503 aborts the db transaction safely when a modifier callback fails.
504 Fixes SF python patch/bug #1408584.
505
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000506- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000507 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000508 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
509 database calls that would previously deadlock. [SF python bug #775414]
510
Vinay Sajip28e57612006-07-01 10:45:20 +0000511- Patch #1446489: add support for the ZIP64 extensions to zipfile.

517-------
518
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000519- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
520 functions.
521
Martin v. Löwis3798da02006-06-17 18:44:27 +0000522- Patch #812986: Update turtle output even if not tracing.
523
Vinay Sajip28e57612006-07-01 10:45:20 +0000524- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000525 Tkinter.BaseWidget.
526
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000527- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
528
Martin v. Löwis337487e2006-06-17 09:15:14 +0000529- Patch #763580: Add name and value arguments to Tkinter variable
530 classes.
531
Georg Brandl83cc0d02006-06-14 08:50:03 +0000532- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
533 mime.types file for determining MIME types.
534
Georg Brandl2605ca82006-06-14 06:08:31 +0000535- Bug #1339007: Shelf objects now don't raise an exception in their
536 __del__ method when initialization failed.
537
Martin v. Löwisd8251432006-06-14 05:21:04 +0000538- Patch #1455898: The MBCS codec now supports the incremental mode for
539 double-byte encodings.
540
Tim Peters43898b42006-06-14 04:09:25 +0000541- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
542 guarantee that adjacent triples in the return list always describe
543 non-adjacent blocks. Previously, a pair of matching blocks could end
544 up being described by multiple adjacent triples that formed a partition
545 of the matching pair.
546
Greg Ward0e0c9f42006-06-11 16:24:11 +0000547- Bug #1498146: fix optparse to handle Unicode strings in option help,
548 description, and epilog.
549
Greg Wardd1c797e2006-06-11 14:42:41 +0000550- Bug #1366250: minor optparse documentation error.
551
Greg Ward7f547402006-06-11 00:40:49 +0000552- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
553 clarify docs.
554
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000555- The wsgiref package has been added to the standard library.
556
Nick Coghlan676725d2006-06-08 13:54:49 +0000557- The functions update_wrapper() and wraps() have been added to the functools
558 module. These make it easier to copy relevant metadata from the original
559 function when writing wrapper functions.
560
Tim Petersd6a9eef2006-06-05 01:48:21 +0000561- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
562 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000563
Martin v. Löwis3f767792006-06-04 19:36:28 +0000564- Patch #1359618: Speed up charmap encoder by using a trie structure
565 for lookup.
566
Tim Petersd609b1a2006-06-02 23:22:51 +0000567- The functions in the ``pprint`` module now sort dictionaries by key
568 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
569 if and only if its display required more than one line, although that
570 wasn't documented. The new behavior increases predictability; e.g.,
571 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
572
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000573- Patch #1497027: try HTTP digest auth before basic auth in urllib2
574 (thanks for J. J. Lee).
575
Georg Brandl2b330372006-05-28 20:23:12 +0000576- Patch #1496206: improve urllib2 handling of passwords with respect to
577 default HTTP and HTTPS ports.
578
George Yoshidaf3c65de2006-05-28 16:39:09 +0000579- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
580
Bob Ippolito7298f272006-05-23 18:43:47 +0000581- Patch #1281707: speed up gzip.readline.
582
Georg Brandlb89316f2006-05-17 15:51:16 +0000583- Patch #1180296: Two new functions were added to the locale module:
584 format_string() to get the effect of "format % items" but locale-aware,
585 and currency() to format a monetary number with currency sign.
586
Georg Brandle3a25832006-05-17 14:56:04 +0000587- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
588 and several features added, such as speed and geometry control.
589
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000590- Patch #1488881: add support for external file objects in bz2 compressed
591 tarfiles.
592
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000593- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
594 stdout arguments, making it possible to redirect input and output
595 for remote debugging.
596
597- Patch #1484695: Update the tarfile module to version 0.8. This fixes
598 a couple of issues, notably handling of long file names using the
599 GNU LONGNAME extension.
600
601- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
602 new flag when ``name`` is already the name of an option flag.
603
604- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
605 package.
606
607- Patch #1472854: make the rlcompleter.Completer class usable on non-
608 UNIX platforms.
609

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000643What's New in Python 2.5 alpha 2?
644=================================
645
646*Release date: 27-APR-2006*
647
648Core and builtins
649-----------------
650
Thomas Heller1b046642006-04-18 18:51:06 +0000651- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
652 by converting these apis from macros into exported functions again:
653
654 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
655 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
656 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
657 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
658 PyRun_String Py_CompileString
659
Martin v. Löwis45294a92006-04-18 06:24:08 +0000660- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
661
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000662- All uses of PyStructSequence_InitType have been changed to initialize
663 the type objects only once, even if the interpreter is initialized
664 multiple times.
665
Neal Norwitz61546162006-04-14 05:20:28 +0000666- Bug #1454485, array.array('u') could crash the interpreter. This was
667 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
668 to unicode when it didn't make sense. 'u#' now requires a unicode string.
669
670- Py_UNICODE is unsigned. It was always documented as unsigned, but
671 due to a bug had a signed value in previous versions.
672
Tim Peters3a5e8b12006-04-11 01:44:07 +0000673- Patch #837242: ``id()`` of any Python object always gives a positive
674 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
675 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000676 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000677 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000678
Tim Peters3a5e8b12006-04-11 01:44:07 +0000679 def __hash__(self):
680 return id(self) # WRONG
681
682 because a hash result must be a (short) Python int but it was always
683 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000684 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000685 was always usable as a hash value before this patch. That's no longer
686 necessarily so.
687
688- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000689 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000690 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000691 #1454844)
692
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000693- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
694 involving generators that have paused outside of any ``try`` or ``with``
695 blocks. (In 2.5a1, a paused generator that was part of a reference
696 cycle could not be garbage collected, regardless of whether it was
697 paused in a ``try`` or ``with`` block.)

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000702- Patch #1191065: Fix preprocessor problems on systems where recvfrom
703 is a macro.
704
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000705- Bug #1467952: os.listdir() now correctly raises an error if readdir()
706 fails with an error condition.
707
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000708- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
709
710- Bug #1117761: bsddb.*open() no longer raises an exception when using
711 the cachesize parameter.
712
713- Bug #1149413: bsddb.*open() no longer raises an exception when using
714 a temporary db (file=None) with the 'n' flag to truncate on open.
715
716- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
717 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000718
Armin Rigoa9017c32006-04-19 11:50:27 +0000719- Patch #1062014: AF_UNIX sockets under Linux have a special
720 abstract namespace that is now fully supported.
721
Anthony Baxter51bcb682006-04-05 14:51:42 +0000722Library
723-------
724
Peter Astrand7d1d4362006-07-14 14:04:45 +0000725- Bug #1223937: subprocess.CalledProcessError reports the exit status
726 of the process using the returncode attribute, instead of
727 abusing errno.
728
Tim Peters711bf302006-04-25 03:31:36 +0000729- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
730 a doctest to be skipped (the code is not run, and the expected output
731 or exception is ignored).
732
Nick Coghlanda2268f2006-04-24 04:37:15 +0000733- Fixed contextlib.nested to cope with exceptions being raised and
734 caught inside exit handlers.
735
Greg Wardab05edc2006-04-23 03:47:58 +0000736- Updated optparse module to Optik 1.5.1 (allow numeric constants in
737 hex, octal, or binary; add ``append_const`` action; keep going if
738 gettext cannot be imported; added ``OptionParser.destroy()`` method;
739 added ``epilog`` for better help generation).
740
Tim Peters21fbd572006-04-21 21:18:10 +0000741- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
742 called from a thread spawned as a side effect of importing a module.
743
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000744- The pydoc module now supports documenting packages contained in
745 .zip or .egg files.
746
747- The pkgutil module now has several new utility functions, such
748 as ``walk_packages()`` to support working with packages that are either
749 in the filesystem or zip files.
750
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000751- The mailbox module can now modify and delete messages from
752 mailboxes, in addition to simply reading them. Thanks to Gregory
753 K. Johnson for writing the code, and to the 2005 Google Summer of
754 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000755
Tim Petersc7605f22006-04-17 21:12:33 +0000756- The ``__del__`` method of class ``local`` in module ``_threading_local``
757 returned before accomplishing any of its intended cleanup.
758
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000759- Patch #790710: Add breakpoint command lists in pdb.
760
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000761- Patch #1063914: Add Tkinter.Misc.clipboard_get().
762
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000763- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
764
Anthony Baxtere29002c2006-04-12 12:07:31 +0000765- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
766 Windows. Bug #1469163.
767
Phillip J. Eby47032112006-04-11 01:07:43 +0000768- The warnings, linecache, inspect, traceback, site, and doctest modules
769 were updated to work correctly with modules imported from zipfiles or
770 via other PEP 302 __loader__ objects.
771
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000772- Patch #1467770: Reduce usage of subprocess._active to processes which
773 the application hasn't waited on.
774
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000775- Patch #1462222: Fix Tix.Grid.
776
Neal Norwitza31bf182006-04-09 03:35:43 +0000777- Fix exception when doing glob.glob('anything*/')
778
Skip Montanaro262fb922006-04-21 02:31:07 +0000779- The pstats.Stats class accepts an optional stream keyword argument to
780 direct output to an alternate file-like object.
781
Anthony Baxter51bcb682006-04-05 14:51:42 +0000782Build
783-----
784
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000785- The Makefile now has a reindent target, which runs reindent.py on
786 the library.
787
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000788- Patch #1470875: Building Python with MS Free Compiler
789
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000790- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000791
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000792- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
793 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000794 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000795 CXX from --with-cxx-main, see description in README.
796
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000797- Patch #1429775: Link extension modules with the shared libpython.
798
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000799- Fixed a libffi build problem on MIPS systems.
800
Tim Peters8931ff12006-05-13 23:28:20 +0000801- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
802 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
803 and "%zu" for unsigned integers of type ``size_t``.
804
Anthony Baxter51bcb682006-04-05 14:51:42 +0000805Tests
806-----
807
Nick Coghlanda2268f2006-04-24 04:37:15 +0000808- test_contextlib now checks contextlib.nested can cope with exceptions
809 being raised and caught inside exit handlers.
810
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000811- test_cmd_line now checks operation of the -m and -c command switches
812
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000813- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
814 it separately and by hand. It also wasn't cleaning up its changes to
815 the current Decimal context.
816
Thomas Woutersabd08882006-04-26 15:53:30 +0000817- regrtest.py now has a -M option to run tests that test the new limits of
818 containers, on 64-bit architectures. Running these tests is only sensible
819 on 64-bit machines with more than two gigabytes of memory. The argument
820 passed is the maximum amount of memory for the tests to use.

829-------------
830
Tim Petersb06d28c2006-05-12 01:57:59 +0000831- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
832
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000833- PEP 343: Added Context Types section to the library reference
834 and attempted to bring other PEP 343 related documentation into
835 line with the implementation and/or python-dev discussions.
836
Tim Peters8dc73d22006-04-24 02:03:16 +0000837- Bug #1337990: clarified that ``doctest`` does not support examples
838 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000841What's New in Python 2.5 alpha 1?
842=================================
843
Anthony Baxterebed3f62006-04-03 15:03:44 +0000844*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000845
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000846Core and builtins
847-----------------
848
Nick Coghlan43832302006-04-23 17:04:07 +0000849- PEP 338: -m command line switch now delegates to runpy.run_module
850 allowing it to support modules in packages and zipfiles
851
Martin v. Löwisc661b882006-04-20 04:54:23 +0000852- On Windows, .DLL is not an accepted file name extension for
853 extension modules anymore; extensions are only found if they
854 end in .PYD.
855
Martin v. Löwisea62d252006-04-03 10:56:49 +0000856- Bug #1421664: sys.stderr.encoding is now set to the same value as
857 sys.stdout.encoding.
858
Neal Norwitz92e212f2006-04-03 04:48:37 +0000859- __import__ accepts keyword arguments.
860
Georg Brandlccadf842006-03-31 18:54:53 +0000861- Patch #1460496: round() now accepts keyword arguments.
862
Anthony Baxter262c00a2006-03-30 10:53:17 +0000863- Fixed bug #1459029 - unicode reprs were double-escaped.
864
Hye-Shik Changd478f342006-03-23 12:32:36 +0000865- Patch #1396919: The system scope threads are reenabled on FreeBSD
866 5.4 and later versions.
867
Neal Norwitze98ccf62006-03-23 05:39:47 +0000868- Bug #1115379: Compiling a Unicode string with an encoding declaration
869 now gives a SyntaxError.
870
Georg Brandlabd1ff82006-03-18 07:59:59 +0000871- Previously, Python code had no easy way to access the contents of a
872 cell object. Now, a ``cell_contents`` attribute has been added
873 (closes patch #1170323).
874
Tim Peterscf79aac2006-03-16 01:14:46 +0000875- Patch #1123430: Python's small-object allocator now returns an arena to
876 the system ``free()`` when all memory within an arena becomes unused
877 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
878 freed. Some applications will see a drop in virtual memory size now,
879 especially long-running applications that, from time to time, temporarily
880 use a large number of small objects. Note that when Python returns an
881 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000882 platform C library will in turn return that memory to the operating system.
883 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000884 appears to be effective at least on Microsoft C and gcc-based systems.
885 Thanks to Evan Jones for hard work and patience.
886
Georg Brandl533ff6f2006-03-08 18:09:27 +0000887- Patch #1434038: property() now uses the getter's docstring if there is
888 no "doc" argument given. This makes it possible to legitimately use
889 property() as a decorator to produce a read-only property.
890
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000891- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
892 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
893 of requiring an int or long in slicing and a few other contexts, enabling
894 other objects (e.g. Numeric Python's integers) to be used as slice indices.
895
Neal Norwitz995acdf2006-03-07 05:01:00 +0000896- Fixed various bugs reported by Coverity's Prevent tool.
897
Brett Cannonbf364092006-03-01 04:25:17 +0000898- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
899 new exception base class, BaseException, which has a new message attribute.
900 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
901 Raising a string exception now raises a DeprecationWarning.
902
Thomas Woutersfb609f42006-02-28 16:37:25 +0000903- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
904 explicitly relative, using 'from .module import name' to mean 'from the same
905 package as this module is in. Imports without dots still default to the
906 old relative-then-absolute, unless 'from __future__ import
907 absolute_import' is used.
908
Brett Cannona7446e32006-02-27 23:39:10 +0000909- Properly check if 'warnings' raises an exception (usually when a filter set
910 to "error" is triggered) when raising a warning for raising string
911 exceptions.
912
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000913- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000914 The name was removed from Include/code.h.
915
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000916- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000917
Guido van Rossum1968ad32006-02-25 22:38:04 +0000918- Patch 1433928:
919 - The copy module now "copies" function objects (as atomic objects).
920 - dict.__getitem__ now looks for a __missing__ hook before raising
921 KeyError.
922
Tim Peters84ef21c2006-02-28 20:39:06 +0000923- PEP 343: with statement implemented. Needs ``from __future__ import
924 with_statement``. Use of 'with' as a variable will generate a warning.
925 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000926 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000927 The following objects have __context__ methods:
928 - The built-in file type.
929 - The thread.LockType type.
930 - The following types defined by the threading module:
931 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
932 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000933
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000934- Fix the encodings package codec search function to only search
935 inside its own package. Fixes problem reported in patch #1433198.
936
937 Note: Codec packages should implement and register their own
938 codec search function. PEP 100 has the details.
939
Tim Peters9ea89d22006-06-04 03:26:02 +0000940- PEP 353: Using ``Py_ssize_t`` as the index type.
941
942- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
943 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
944 now allow Python to make use of memory blocks exceeding 2**32 bytes for
945 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
946 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000947
Neal Norwitzfc76d632006-01-10 06:03:13 +0000948- Patch #1400181, fix unicode string formatting to not use the locale.
949 This is how string objects work. u'%f' could use , instead of .
950 for the decimal point. Now both strings and unicode always use periods.
951
Neal Norwitz671b9e32006-01-09 07:07:12 +0000952- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
953 configure would break checking curses.h.
954
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000955- Bug #959576: The pwd module is now builtin. This allows Python to be
956 built on UNIX platforms without $HOME set.
957
Neal Norwitzc10978f2005-12-19 06:07:16 +0000958- Bug #1072182, fix some potential problems if characters are signed.
959
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000960- Bug #889500, fix line number on SyntaxWarning for global declarations.
961
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000962- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
963
Neal Norwitze7214a12005-12-18 05:03:17 +0000964- Support for converting hex strings to floats no longer works.
965 This was not portable. float('0x3') now raises a ValueError.
966
Barry Warsaw2a38a862005-12-18 01:27:35 +0000967- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000968 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000969 is now displayed in interactive prompt banner.
970
Georg Brandlfa166682005-12-17 21:45:17 +0000971- Implementation of PEP 341 - Unification of try/except and try/finally.
972 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000973 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000974
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000975- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
976 now encodes backslash correctly.
977
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000978- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
979
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000980- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000981 and long longs.
982
Neal Norwitz67715f02005-11-09 06:59:35 +0000983- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000984 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000985 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000986
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000987- Replaced most Unicode charmap codecs with new ones using the
988 new Unicode translate string feature in the builtin charmap
989 codec; the codecs were created from the mapping tables available
990 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
991 encodings now include a mapping for the Apple logo)
992
Tim Peterse3547fd2005-12-16 23:13:57 +0000993- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000994
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000995- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000996
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000997- A new AST parser implementation was completed. The abstract
998 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000999 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001000
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001001- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001002 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1003
Neal Norwitz708e51a2005-10-03 04:48:15 +00001004- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1005
Neal Norwitz11bd1192005-10-03 00:54:56 +00001006- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1007 Provide a warning when a directory is passed on the command line.
1008
Neal Norwitz40d37812005-10-02 01:48:49 +00001009- Fix segfault with invalid coding.
1010
1011- SF bug #772896: unknown encoding results in MemoryError.
1012
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001013- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001014 supported a __len__() method which evaluated to False when the iterator
1015 was empty.
1016
Guido van Rossum630db602005-09-20 18:49:54 +00001017- On 64-bit platforms, when __len__() returns a value that cannot be
1018 represented as a C int, raise OverflowError.
1019
Skip Montanarof8948ca2005-09-19 03:54:46 +00001020- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001021 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001022
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001023- SF bug #893549: parsing keyword arguments was broken with a few format
1024 codes.
1025
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001026- Changes donated by Elemental Security to make it work on AIX 5.3
1027 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1028 bug #105470: test_pwd fails on 64bit system (Opteron).
1029
Guido van Rossum539c6622005-09-14 17:49:54 +00001030- Changes donated by Elemental Security to make it work on HP-UX 11 on
1031 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1032
Georg Brandl4550b8d2005-08-26 06:43:52 +00001033- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001034 (fixes bug #1119418).
1035
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001036- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1037
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001038- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1039 exceptions that cause a function to exit.
1040
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001041- The implementation of set() and frozenset() was revised to use its
1042 own internal data structure. Memory consumption is reduced by 1/3
1043 and there are modest speed-ups as well. The API is unchanged.
1044
Tim Petersde7990b2005-07-17 23:45:23 +00001045- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1046
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001047- SF bug #1229429: PyObject_CallMethod failed to decrement some
1048 reference counts in some error exit cases.
1049
Tim Petersecc6e6a2005-07-10 22:30:55 +00001050- SF bug #1185883: Python's small-object memory allocator took over
1051 a block managed by the platform C library whenever a realloc specified
1052 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001053 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001054 portable way to copy data from the C-managed block into Python's
1055 small-object space without risking a memory fault. Python's small-object
1056 realloc now leaves such blocks under the control of the platform C
1057 realloc.
1058
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001059- SF bug #1232517: An overflow error was not detected properly when
1060 attempting to convert a large float to an int in os.utime().
1061
Raymond Hettinger3296e692005-06-29 23:29:56 +00001062- SF bug #1224347: hex longs now print with lowercase letters just
1063 like their int counterparts.
1064
Michael W. Hudson188d4362005-06-20 16:52:57 +00001065- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1066 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1067 interpreter states; back out that fix and do a better job (see
1068 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1069 for a longer write-up of the problem).
1070
Michael W. Hudsondf888462005-06-03 14:41:55 +00001071- SF patch #1180995: marshal now uses a binary format by default when
1072 serializing floats.
1073
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001074- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1075 the routines that promise to produce IEEE 754 binary representations
1076 of floats now simply copy bytes around.
1077
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001078- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1079 278.
1080
Brett Cannonc3647ac2005-04-26 03:45:26 +00001081- patch #1109424: int, long, float, complex, and unicode now check for the
1082 proper magic slot for type conversions when subclassed. Previously the
1083 magic slot was ignored during conversion. Semantics now match the way
1084 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001085 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001086 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001087 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001088
Barry Warsawc8d907c2005-04-19 23:43:40 +00001089- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1090 NULL, now raise an AttributeError when attempting to set or delete the
1091 attribute. Previously a TypeError was raised, but this was inconsistent
1092 with the equivalent pure-Python implementation.
1093
Michael W. Hudson774479c2005-04-18 08:46:17 +00001094- It is now safe to call PyGILState_Release() before
1095 PyEval_InitThreads() (note that if there is reason to believe there
1096 are multiple threads around you still must call PyEval_InitThreads()
1097 before using the Python API; this fix is for extension modules that
1098 have no way of knowing if Python is multi-threaded yet).
1099
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001100- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1101 disabled caused a crash.
1102
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001103- Bug #1165306: instancemethod_new allowed the creation of a method
1104 with im_class == im_self == NULL, which caused a crash when called.
1105
Tim Petersecc6e6a2005-07-10 22:30:55 +00001106- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001107 fixes the crash seen in bug #1165761
1108
Raymond Hettinger96229b12005-03-11 06:49:40 +00001109- Added two new builtins, any() and all().
1110
Brett Cannon409d8f22005-03-05 06:47:57 +00001111- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001112 (e.g., ``class C(): pass`` is no longer a syntax error).
1113 Patch #1176012 added support to the 'parser' module and 'compiler' package
1114 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001115
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001116- Patch #1115086: Support PY_LONGLONG in structmember.
1117
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001118- Bug #1155938: new style classes did not check that __init__() was
1119 returning None.
1120
Tim Petersecc6e6a2005-07-10 22:30:55 +00001121- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001122 ('\') with a specific error message.
1123
Martin v. Löwisff232d72005-03-03 09:24:38 +00001124- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1125
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001126- Bug #1124295: the __name__ attribute of file objects was
1127 inadvertently made inaccessible in restricted mode.
1128
Tim Petersecc6e6a2005-07-10 22:30:55 +00001129- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001130 an ferror() call.
1131
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001132- min() and max() now support key= arguments with the same meaning as in
1133 list.sort().
1134
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001135- The peephole optimizer now performs simple constant folding in expressions:
1136 (2+3) --> (5).
1137
Raymond Hettingera422c342005-01-11 03:03:27 +00001138- set and frozenset objects can now be marshalled. SF #1098985.
1139
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001140- Bug #1077106: Poor argument checking could cause memory corruption
1141 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001142
Jeremy Hyltonab630502005-02-04 18:44:06 +00001143- The parser did not complain about future statements in illegal
1144 positions. It once again reports a syntax error if a future
1145 statement occurs after anything other than a doc string.
1146
Neil Schemenauercf52c072005-08-12 17:34:58 +00001147- Change the %s format specifier for str objects so that it returns a
1148 unicode instance if the argument is not an instance of basestring and
1149 calling __str__ on the argument returns a unicode instance.
1150
Tim Petersf4e69282006-02-27 17:15:31 +00001151- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1152 current thread state when the auto-GIL-state machinery knows about
1153 it (since the thread state is being deleted, continuing to remember it
1154 can't help, but can hurt if another thread happens to get created with
1155 the same thread id).
1156
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001157Extension Modules
1158-----------------
1159
Georg Brandl43f08a82006-03-31 18:01:16 +00001160- Patch #1380952: fix SSL objects timing out on consecutive read()s
1161
Neal Norwitz05a45592006-03-20 06:30:08 +00001162- Patch #1309579: wait3 and wait4 were added to the posix module.
1163
Anthony Baxterfa869072006-03-20 05:21:58 +00001164- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1165 In addition, the existing ulaw code was updated.
1166
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001167- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001168 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001169
Neal Norwitz10be10c2006-03-16 06:50:13 +00001170- Everything under lib-old was removed. This includes the following modules:
1171 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001172 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001173 util, whatsound, whrandom, zmod
1174
1175- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1176
1177- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001178 is deprecated. The undocumented re.engine variable no longer exists.
1179
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001180- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1181 SS2 (single-shift 2) escape sequences correctly.
1182
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001183- The unicodedata module was updated to the 4.1 version of the Unicode
1184 database. The 3.2 version is still available as unicodedata.db_3_2_0
1185 for applications that require this specific version (such as IDNA).
1186
Neal Norwitzb62c4332006-03-04 18:35:47 +00001187- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001347- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1348 been renamed to have only a single underscore prefix. This was done to
1349 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001350
Nick Coghlan43832302006-04-23 17:04:07 +00001351- PEP 338: new module runpy defines a run_module function to support
1352 executing modules which provide access to source code or a code object
1353 via the PEP 302 import mechanisms.
1354
Anthony Baxter93f5b932006-04-03 08:05:07 +00001355- The email module's parsedate_tz function now sets the daylight savings

1363 in attribute values.
1364
Anthony Baxterc51ee692006-04-01 00:57:31 +00001365- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001366 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001367 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001368 module will not be built.
1369
Tim Petersc17976e2006-04-01 00:26:53 +00001370- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1371 aren't officially supported here, and trying to use them will probably
1372 raise an exception some day. But dicts have been allowed, and "mostly
1373 worked", so support for them won't go away without warning.
1374
Georg Brandl338ef7d2006-03-31 18:42:16 +00001375- Bug #1445068: getpass.getpass() can now be given an explicit stream
1376 argument to specify where to write the prompt.

1393
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001394- email 4.0 package now integrated. This is largely the same as the email 3.0
1395 package that was included in Python 2.3, except that PEP 8 module names are
1396 now used (e.g. mail.message instead of email.Message). The MIME classes
1397 have been moved to a subpackage (e.g. email.mime.text instead of
1398 email.MIMEText). The old names are still supported for now. Several
1399 deprecated Message methods have been removed and lots of bugs have been
1400 fixed. More details can be found in the email package documentation.
1401
Walter Dörwald40108c92006-03-27 08:15:44 +00001402- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1403 (a subclass of tuple) that provides incremental decoders and encoders
1404 (a way to use stateful codecs without the stream API). Python functions
1405 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1406 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1407 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001409- Patch #1359365: Calling next() on a closed StringIO.String object raises
1410 a ValueError instead of a StopIteration now (like file and cString.String do).
1411 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1412 called before (like file and StringIO.StringIO do).

1480
Neal Norwitz338e7862005-12-23 21:27:46 +00001481- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1482 LoadError as documented, instead of IOError. For compatibility,
1483 LoadError subclasses IOError.
1484
Brett Cannon3cbd0382005-12-16 22:49:23 +00001485- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001486 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1487 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1488 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1489 Ronald L. Rivest offered this advice for Python:
1490
1491 "The consensus of researchers in this area (at least as
1492 expressed at the NIST Hash Function Workshop 10/31/05),
1493 is that SHA-256 is a good choice for the time being, but
1494 that research should continue, and other alternatives may
1495 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001496
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001497- Added a subset of Fredrik Lundh's ElementTree package. Available

1550 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001551 correct line numbers for decoding errors in source code.

1590 Bug #1224621.
1591
Raymond Hettinger68c04532005-06-10 11:05:19 +00001592- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001593 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001594 the generate_tokens() function now accepts a callable argument that
1595 terminates by raising StopIteration.
1596
Georg Brandl9166e1a2005-06-04 09:20:03 +00001597- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1614 instead of raising a TypeError when interacting with other types. This
1615 allows other classes to implement __radd__ style methods and have them
1616 work as expected.
1617
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001618- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00001656- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1657 disables recursive traversal through instance attributes, which can
1658 be exploited in various ways.
1659
Tim Peterse3547fd2005-12-16 23:13:57 +00001660- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001661 flags on the HTTP listening socket.
1662

1672
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001673- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1674
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001675- Enhancements to the csv module:
1676
1677 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001678 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001679 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001680 + Dialect parameter parsing has been re-implemented to improve error
1681 reporting.
1682 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1683 dictates.
1684 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001685 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001686 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001687 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1688 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001689 + reader now allows \r characters to be quoted (previously it only allowed
1690 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001691 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001692 + Dialect classes passed to the module are no longer instantiated by
1693 the module before being parsed (the former validation scheme required
1694 this, but the mechanism was unreliable).
1695 + The dialect registry now contains instances of the internal
1696 C-coded dialect type, rather than references to python objects.
1697 + the internal c-coded dialect type is now immutable.
1698 + register_dialect now accepts the same keyword dialect specifications
1699 as the reader and writer, allowing the user to register dialects
1700 without first creating a dialect class.
1701 + a configurable limit to the size of parsed fields has been added -
1702 previously, an unmatched quote character could result in the entire
1703 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001704 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001705 the parser field size limit (returning the former limit). The initial
1706 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001707 + A line_num attribute has been added to the reader object, which tracks
1708 the number of lines read from the source iterator. This is not
1709 the same as the number of records returned, as records can span
1710 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001711 + reader and writer objects were not being registered with the cyclic-GC.
1712 This has been fixed.
1713
Brett Cannone6539c42005-01-08 02:43:53 +00001714- _DummyThread objects in the threading module now delete self.__block that is
1715 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1716 lock primitives tend to be limited in number and thus should not be wasted on
1717 a _DummyThread object. Fixes bug #1089632.
1718
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001719- The imghdr module now detects Exif files.
1720
Raymond Hettinger6065d322004-12-20 23:51:53 +00001721- StringIO.truncate() now correctly adjusts the size attribute.
1722 (Bug #951915).
1723
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001724- locale.py now uses an updated locale alias table (built using
1725 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1726 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001727 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001728
Raymond Hettinger3557f422004-12-07 12:02:02 +00001729- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1730
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001731- the pickle module no longer accepts the deprecated None option in the
1732 args tuple returned by __reduce__().
1733
Brett Cannon84667c02004-12-07 03:25:18 +00001734- optparse now optionally imports gettext. This allows its use in setup.py.
1735
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001736- the pickle module no longer uses the deprecated bin parameter.
1737
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001738- the shelve module no longer uses the deprecated binary parameter.
1739

1741
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001742- the filecmp module no longer uses the deprecated use_statcache argument.
1743
Raymond Hettinger664347b2004-12-04 21:21:53 +00001744- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1745 extended or overridden by subclasses. Formerly, the subclassed method would
1746 be ignored by the rest of the module. (Bug #1078905).
1747
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001748- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001749 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001750
Walter Dörwald36733692004-12-22 12:50:50 +00001751- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1752 once when a size argument is given. This prevents a buffer overflow in the
1753 tokenizer with very long source lines.
1754
Barry Warsaw538561e2006-01-01 21:48:54 +00001755- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1756 immediately after creating the object, without any intervening
1757 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001758
Skip Montanaro05885812005-01-16 20:48:27 +00001759- The reconvert.quote function can now emit triple-quoted strings. The
1760 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001761
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001762- ``UserString.MutableString`` now supports negative indices in
1763 ``__setitem__`` and ``__delitem__``
1764
Greg Ward40407942005-03-05 02:53:17 +00001765- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1766 correctly.
1767
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001768- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1769 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1770 character even if the user has passed a size parameter to get a proper
1771 line ending. Remove the special handling of a "\r\n" that has been split
1772 between two lines.
1773
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001774- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1775 about illegal code points. The codec now supports PEP 293 style error
1776 handlers.
1777
Walter Dörwald78a78b02005-09-01 12:04:29 +00001778- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001779 from the input stream, so that the output is a byte string in the correct
1780 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001781
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001782- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1783 considering it exactly like a '*'.
1784
Walter Dörwald007f8df2005-10-09 19:42:27 +00001785- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1786 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001787
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001788- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1789
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001790- Patch #1413711: Certain patterns of differences were making difflib
1791 touch the recursion limit.
1792
Walter Dörwald58917a62006-03-31 15:26:22 +00001793- Bug #947906: An object oriented interface has been added to the calendar
1794 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001795 called as a script (e.g. via ``python -mcalendar``). Localized month and
1796 weekday names can be ouput (even if an exotic encoding is used) using
1797 special classes that use unicode.

1800-----
1801
Neal Norwitz602d3392006-03-31 08:21:40 +00001802- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1803 by using -mieee gcc option.
1804
Martin v. Löwis86d66262006-02-17 08:40:11 +00001805- Patch #1432345: Make python compile on DragonFly.
1806
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001807- Build support for Win64-AMD64 was added.
1808
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001809- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1810
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001811- Patch #881820: look for openpty and forkpty also in libbsd.
1812
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001813- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1814 The zlib module is now builtin on Windows.
1815
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001816- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1817
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001818- Bug #1189330: configure did not correctly determine the necessary
1819 value of LINKCC if python was built with GCC 4.0.
1820
Trent Mick8321b422005-07-26 02:29:21 +00001821- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1822 vulnerability in zlib 1.2.1 and 1.2.2.
1823
Brett Cannon08cd5982005-04-24 22:26:38 +00001824- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1825 flags that change binary compatibility. Changes were also made to
1826 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001827 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001828
Bob Ippolitoed233462005-03-29 13:47:59 +00001829- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1830 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1831 no longer exists). This configure patch makes things right.
1832
Martin v. Löwise2713be2005-03-08 15:03:08 +00001833- Bug #1158607: Build with --disable-unicode again.
1834
Brett Cannon46d96232005-02-16 00:07:19 +00001835- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1836 defined. Discovered as a result of not being able to build on OS X.
1837
Brett Cannon516592f2004-12-07 00:42:59 +00001838- setup.py now uses the directories specified in LDFLAGS using the -L option
1839 and in CPPFLAGS using the -I option for adding library and include
1840 directories, respectively, for compiling extension modules against. This has
1841 led to the core being compiled using the values in CPPFLAGS. It also removes
1842 the need for the special-casing of both DarwinPorts and Fink for darwin since
1843 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1844 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1845 Fink, ``-I/opt/local/include`` for DarwinPorts).
1846
Brett Cannon43802422005-02-10 20:48:03 +00001847- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1848 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1849 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1850 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001852C API
1853-----
1854
Tim Petersc9d78aa2006-03-26 23:27:58 +00001855- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1856 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1857 is obtained via the ``PyObject_`` family, it must be released via the
1858 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1859 always been officially true, but when Python's small-object allocator was
1860 introduced, an attempt was made to cater to a few extension modules
1861 discovered at the time that obtained memory via ``PyObject_New`` but
1862 released it via ``PyMem_DEL``. It's years later, and if such code still
1863 exists it will fail now (probably with segfaults, but calling wrong
1864 low-level memory management functions can yield many symptoms).
1865
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001866- Added a C API for set and frozenset objects.
1867
Raymond Hettinger66517482004-12-03 11:45:13 +00001868- Removed PyRange_New().
1869
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001870- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1871 mapping argument now. This string is used as a mapping table. Byte values
1872 greater than the length of the string and 0xFFFE are treated as undefined
1873 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001880
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001881- Patch #1276356: New resource "urlfetch" is implemented. This enables
