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
Fred Drakefbdeaad2006-07-29 16:56:15 +000055- Rename of the xml package to xmlcore, and the import hackery done to
56 make it appear at both names, has been removed. Bug #1511497,
57 #1513611, and probably others.
58
Georg Brandledd9b0d2006-07-29 09:33:26 +000059- Bug #1441397: The compiler module now recognizes module and function
60 docstrings correctly as it did in Python 2.4.
61
Tim Peters6f681472006-07-27 23:44:37 +000062- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
63 lost that tests are sorted by name before being run. This rarely
64 matters for well-written tests, but can create baffling symptoms if
65 side effects from one test to the next affect outcomes. ``DocTestFinder``
66 has been changed to sort the list of tests it returns.
67
Martin v. Löwis997ceff2006-07-27 06:38:16 +000068- The distutils version has been changed to 2.5.0.
69
Martin v. Löwis9298eff2006-07-26 12:12:56 +000070- Bug #978833: Really close underlying socket in _socketobject.close.
71
Georg Brandl0619a322006-07-26 07:40:17 +000072- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
73 with title().
74
Georg Brandlcf0c1722006-07-26 07:23:32 +000075- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
76 to recursive calls and call it with the failing package name.
77
Martin v. Löwis0b483032006-07-25 09:53:12 +000078- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
79
Georg Brandlc13c34c2006-07-24 14:09:56 +000080- Patch #1515343: Fix printing of deprecated string exceptions with a
81 value in the traceback module.
82
Greg Ward48fae7a2006-07-23 16:05:51 +000083- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
84
Martin v. Löwis426f4a12006-07-18 17:46:31 +000085- Patch #1524429: Use repr() instead of backticks in Tkinter again.
86
Brett Cannoncaebe222006-07-18 04:41:36 +000087- Bug #1520914: Change time.strftime() to accept a zero for any position in its
88 argument tuple. For arguments where zero is illegal, the value is forced to
89 the minimum value that is correct. This is to support an undocumented but
90 common way people used to fill in inconsequential information in the time
91 tuple pre-2.4.
92
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000093- Patch #1220874: Update the binhex module for Mach-O.
94
Barry Warsawb110bad2006-07-21 14:51:07 +000095- The email package has improved RFC 2231 support, specifically for
96 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
97 (name*0=<blah>) parameter continuations. This may change the types of
98 values returned from email.message.Message.get_param() and friends.
99 Specifically in some cases where non-encoded continuations were used,
100 get_param() used to return a 3-tuple of (None, None, string) whereas now it
101 will just return the string (since non-encoded continuations don't have
102 charset and language parts).
103
104 Also, whereas % values were decoded in all parameter continuations, they are
105 now only decoded in encoded parameter parts.
106
Ronald Oussoren3075e162006-07-25 20:28:55 +0000107- Bug #1517990: IDLE keybindings on MacOS X now work correctly
108
109- Bug #1517996: IDLE now longer shows the default Tk menu when a
110 path browser, class browser or debugger is the frontmost window on MacOS X
111
Barry Warsaw00decd72006-07-27 23:43:15 +0000112- Patch #1520294: Support for getset and member descriptors in types.py,
113 inspect.py, and pydoc.py. Specifically, this allows for querying the type
114 of an object against these built-in types and more importantly, for getting
115 their docstrings printed in the interactive interpreter's help() function.
116
Ronald Oussoren3075e162006-07-25 20:28:55 +0000117
Neal Norwitza1f10902006-07-12 07:28:29 +0000118Extension Modules
119-----------------
120
Thomas Heller1393d6a2006-07-28 21:43:20 +0000121- Patch #1529514: The _ctypes extension is now compiled on more
122 openbsd target platforms.
123
Tim Peters9cab5932006-07-28 00:30:00 +0000124- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
125 a memory leak, affecting pickles and deep copies.
126
Tim Petersbc24eee2006-07-27 01:14:53 +0000127- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000128 Paul Eggert.
129

131
Thomas Hellerce049a02006-07-14 17:51:14 +0000132- Patch #1521817: Index range checking on ctypes arrays containing
133 exactly one element enabled again. This allows iterating over these
134 arrays, without the need to check the array size before.
135
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000136- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000137 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000138 /dev/null in certain cases; this is now fixed.
139
Thomas Heller47d7a062006-07-12 08:43:47 +0000140- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
141 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000142
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000143- Because of a misspelled preprocessor symbol, ctypes was always
144 compiled without thread support; this is now fixed.
145
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000146- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
147 methods now allow their database parameter to be None as the
148 sleepycat API allows.
149
Matt Flemingec926502006-07-28 11:27:27 +0000150- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
151 bluetooth API compared with Linux and FreeBSD.
152
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000153Tests
154-----
155
156- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
157 how long the test file should take to play. Now accepts taking 2.93 secs
158 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
159
Georg Brandl4793aa32006-07-28 18:31:39 +0000160- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
161 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
162 run via ``regrtest.py``. Now they do.

170Core and builtins
171-----------------
172
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000173- Bug #1441486: The literal representation of -(sys.maxint - 1)
174 again evaluates to a int object, not a long.
175
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000176- Bug #1501934: The scope of global variables that are locally assigned
177 using augmented assignment is now correctly determined.
178
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000179- Bug #927248: Recursive method-wrapper objects can now safely
180 be released.
181
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000182- Bug #1417699: Reject locale-specific decimal point in float()
183 and atof().
184
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000185- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
186 omit a default "error" argument for NULL pointer. This allows
187 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000188
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000189- Bug #1519018: 'as' is now validated properly in import statements.
190
Neal Norwitz28746ab2006-07-09 22:14:42 +0000191- On 64 bit systems, int literals that use less than 64 bits are
192 now ints rather than longs.
193
Neal Norwitzed657552006-07-10 00:04:44 +0000194- Bug #1512814, Fix incorrect lineno's when code at module scope
195 started after line 256.
196
Tim Peters32a83612006-07-10 21:08:24 +0000197- New function ``sys._current_frames()`` returns a dict mapping thread
198 id to topmost thread stack frame. This is for expert use, and is
199 especially useful for debugging application deadlocks. The functionality
200 was previously available in Fazal Majid's ``threadframe`` extension
201 module, but it wasn't possible to do this in a wholly threadsafe way from
202 an extension.
203
Georg Brandlad29e632006-06-21 17:45:17 +0000204Library
205-------
206
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000207- Patch #1519566: Update turtle demo, make begin_fill idempotent.
208
Tim Peters32a83612006-07-10 21:08:24 +0000209- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000210 environment variable to be set in order to the SDK environment
211 for finding the compiler, include files, etc.
212
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000213- Bug #1515998: Properly generate logical ids for files in bdist_msi.
214
Nick Coghlan2d792252006-07-06 13:47:18 +0000215- warnings.py now ignores ImportWarning by default
216
Thomas Woutersadd19112006-07-05 11:03:49 +0000217- string.Template() now correctly handles tuple-values. Previously,
218 multi-value tuples would raise an exception and single-value tuples would
219 be treated as the value they contain, instead.
220
Martin v. Löwisede77f52006-07-03 13:01:35 +0000221- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
222 even if some data are received.
223
Martin v. Löwis45482392006-07-03 12:28:58 +0000224- Bug #1267547: Put proper recursive setup.py call into the
225 spec file generated by bdist_rpm.
226

228 degrees and radians.
229
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000230- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000231 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000232
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000233- Bug #1514703: Only setup canvas window in turtle when the canvas
234 is created.
235
Martin v. Löwis7596e832006-07-01 15:33:37 +0000236- Bug #1513223: .close() of a _socketobj now releases the underlying
237 socket again, which then gets closed as it becomes unreferenced.

243 sgmllib ('[' and ']' were not accepted).
244
Georg Brandl1be63af2006-06-28 20:23:25 +0000245- Fix a bug in the turtle module's end_fill function.
246
Brett Cannon53ab5b72006-06-22 16:49:14 +0000247- Bug #1510580: The 'warnings' module improperly required that a Warning
248 category be either a types.ClassType and a subclass of Warning. The proper
249 check is just that it is a subclass with Warning as the documentation states.
250
Georg Brandlad29e632006-06-21 17:45:17 +0000251- The compiler module now correctly compiles the new try-except-finally
252 statement (bug #1509132).
253
Neal Norwitz60373cd2006-06-22 06:30:50 +0000254- The wsgiref package is now installed properly on Unix.
255
Vinay Sajip28e57612006-07-01 10:45:20 +0000256- A bug was fixed in logging.config.fileConfig() which caused a crash on
257 shutdown when fileConfig() was called multiple times.
258
Gerhard Häring762fbd32006-07-02 17:48:30 +0000259- The sqlite3 module did cut off data from the SQLite database at the first
260 null character before sending it to a custom converter. This has been fixed
261 now.
262
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000263Extension Modules
264-----------------
265
Tim Peters112aad32006-07-19 00:03:19 +0000266- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
267 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
268 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000269
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000270- Assigning None to pointer type fields in ctypes structures possible
271 overwrote the wrong fields, this is fixed now.
272
273- Fixed a segfault in _ctypes when ctypes.wintypes were imported
274 on non-Windows platforms.
275
276- Bug #1518190: The ctypes.c_void_p constructor now accepts any
277 integer or long, without range checking.
278
279- Patch #1517790: It is now possible to use custom objects in the ctypes
280 foreign function argtypes sequence as long as they provide a from_param
281 method, no longer is it required that the object is a ctypes type.
282
283- The '_ctypes' extension module now works when Python is configured
284 with the --without-threads option.
285
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000286- Bug #1513646: os.access on Windows now correctly determines write
287 access, again.
288
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000289- Bug #1512695: cPickle.loads could crash if it was interrupted with
290 a KeyboardInterrupt.
291
Neal Norwitza12aa882006-07-06 06:45:08 +0000292- Bug #1296433: parsing XML with a non-default encoding and
293 a CharacterDataHandler could crash the interpreter in pyexpat.

301
Tim Peters32a83612006-07-10 21:08:24 +0000302- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000303 Previously, the slight difference could cause compilation errors of the
304 'zlib' module on systems with more than one version of zlib.
305
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000306- The MSI compileall step was fixed to also support a TARGETDIR
307 with spaces in it.
308
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000309- Bug #1517388: sqlite3.dll is now installed on Windows independent
310 of Tcl/Tk.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000335
336Core and builtins
337-----------------
338
Georg Brandla56b9152006-06-19 06:35:54 +0000339- Patch #1507676: Error messages returned by invalid abstract object operations
340 (such as iterating over an integer) have been improved and now include the
341 type of the offending object to help with debugging.
342
Brett Cannonea3912b2006-06-13 21:46:41 +0000343- Bug #992017: A classic class that defined a __coerce__() method that returned
344 its arguments swapped would infinitely recurse and segfault the interpreter.
345
Neal Norwitz909eb122006-06-12 02:13:21 +0000346- Fix the socket tests so they can be run concurrently.
347
Neal Norwitzb9845e72006-06-12 02:11:18 +0000348- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000349 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000350
Brett Cannon22565aa2006-06-09 22:31:23 +0000351- Bug #532646: object.__call__() will continue looking for the __call__
352 attribute on objects until one without one is found. This leads to recursion
353 when you take a class and set its __call__ attribute to an instance of the
354 class. Originally fixed for classic classes, but this fix is for new-style.
355 Removes the infinite_rec_3 crasher.
356
Georg Brandl24250812006-06-09 18:45:48 +0000357- The string and unicode methods startswith() and endswith() now accept
358 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
359
Brett Cannonde3b0522006-06-08 17:00:45 +0000360- Buffer objects, at the C level, never used the char buffer
361 implementation even when the char buffer for the wrapped object was
362 explicitly requested (originally returned the read or write buffer).
363 Now a TypeError is raised if the char buffer is not present but is
364 requested.
365
Georg Brandlddbaa662006-06-04 21:56:52 +0000366- Patch #1346214: Statements like "if 0: suite" are now again optimized
367 away like they were in Python 2.4.
368
Georg Brandlb7c8f542006-05-27 12:30:25 +0000369- Builtin exceptions are now full-blown new-style classes instead of
370 instances pretending to be classes, which speeds up exception handling
371 by about 80% in comparison to 2.5a2.
372
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000373- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
374 Unicode 4.1.
375
Georg Brandlf4ef1162006-05-26 18:03:31 +0000376- Patch #921466: sys.path_importer_cache is now used to cache valid and
377 invalid file paths for the built-in import machinery which leads to
378 fewer open calls on startup.
379
Tim Peters696cf432006-05-24 21:10:40 +0000380- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
381 of-2 bases. The largest speedup is for inputs with about 1000 decimal
382 digits. Conversion from non-power-of-2 bases remains quadratic-time in
383 the number of input digits (it was and remains linear-time for bases
384 2, 4, 8, 16 and 32).
385
Tim Petersb713ec22006-05-23 18:45:30 +0000386- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
387 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
388 an integer close to ``sys.maxint``. This was repaired by patch
389 #1335972, which also gives a nice speedup.
390
Richard Jonescebbefc2006-05-23 18:28:17 +0000391- Patch #1337051: reduced size of frame objects.
392
393- PyErr_NewException now accepts a tuple of base classes as its
394 "base" parameter.
395
Richard Jones7c88dcc2006-05-23 10:37:38 +0000396- Patch #876206: function call speedup by retaining allocated frame
397 objects.
398
Georg Brandl7b90e162006-05-18 07:01:27 +0000399- Bug #1462152: file() now checks more thoroughly for invalid mode
400 strings and removes a possible "U" before passing the mode to the
401 C library function.
402
Neal Norwitz1004a532006-05-15 07:17:23 +0000403- Patch #1488312, Fix memory alignment problem on SPARC in unicode
404
Neal Norwitz373f0a72006-05-15 07:04:36 +0000405- Bug #1487966: Fix SystemError with conditional expression in assignment
406
Martin v. Löwis879768d2006-05-11 13:28:43 +0000407- WindowsError now has two error code attributes: errno, which carries
408 the error values from errno.h, and winerror, which carries the error
409 values from winerror.h. Previous versions put the winerror.h values
410 (from GetLastError()) into the errno attribute.
411
Martin v. Löwis77736712006-05-04 05:51:03 +0000412- Patch #1475845: Raise IndentationError for unexpected indent.
413
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000414- Patch #1479181: split open() and file() from being aliases for each other.
415
Tim Peters44bd9862006-06-01 13:49:23 +0000416- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
417 methods were always silently ignored by dictionaries when comparing keys.
418 They are now passed through (except when using the C API function
419 ``PyDict_GetItem()``, whose semantics did not change).
420
421- Bug #1456209: In some obscure cases it was possible for a class with a
422 custom ``__eq__()`` method to confuse dict internals when class instances
423 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
424 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000426Extension Modules
427-----------------
428
Trent Mick960a3f82006-06-28 20:30:41 +0000429- Bug #1295808: expat symbols should be namespaced in pyexpat
430
431- Patch #1462338: Upgrade pyexpat to expat 2.0.0
432
Brett Cannon6ee7d012006-06-08 16:23:04 +0000433- Change binascii.hexlify to accept a read-only buffer instead of only a char
434 buffer and actually follow its documentation.
435
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000436- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
437
Nick Coghlanc649ec52006-05-29 12:43:05 +0000438- Patch #1478788 (modified version): The functional extension module has
439 been renamed to _functools and a functools Python wrapper module added.
440 This provides a home for additional function related utilities that are
441 not specifically about functional programming. See PEP 309.
442
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000443- Patch #1493701: performance enhancements for struct module.
444
Georg Brandl378d5922006-05-17 14:26:50 +0000445- Patch #1490224: time.altzone is now set correctly on Cygwin.
446
Georg Brandl8d3342b2006-05-16 07:38:27 +0000447- Patch #1435422: zlib's compress and decompress objects now have a
448 copy() method.
449
Andrew MacIntyre92913322006-06-13 15:04:24 +0000450- Patch #1454481: thread stack size is now tunable at runtime for thread
451 enabled builds on Windows and systems with Posix threads support.
452
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000453- On Win32, os.listdir now supports arbitrarily-long Unicode path names
454 (up to the system limit of 32K characters).
455
456- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
457 As a result, these functions now raise WindowsError instead of OSError.
458
Tim Peters7a822da2006-05-25 21:50:17 +0000459- ``time.clock()`` on Win64 should use the high-performance Windows
460 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
461 Windows platforms).
462
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000463- Calling Tk_Init twice is refused if the first call failed as that
464 may deadlock.
465
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000466- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
467 accept it without potentially using an uninitialized pointer.
468
469- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
470 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
471 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000472
Gregory P. Smith372b5832006-06-05 18:48:21 +0000473- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000474 [pybsddb project SF patch number 1466734]
475
Gregory P. Smith372b5832006-06-05 18:48:21 +0000476- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
477 parameter is supplied. [SF pybsddb bug #1477863]
478
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000479- bsddb: the __len__ method of a DB object has been fixed to return correct
480 results. It could previously incorrectly return 0 in some cases.
481 Fixes SF bug 1493322 (pybsddb bug 1184012).
482
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000483- bsddb: the bsddb.dbtables Modify method now raises the proper error and
484 aborts the db transaction safely when a modifier callback fails.
485 Fixes SF python patch/bug #1408584.
486
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000487- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000488 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000489 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
490 database calls that would previously deadlock. [SF python bug #775414]
491
Vinay Sajip28e57612006-07-01 10:45:20 +0000492- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000493
Walter Dörwald4994d952006-06-19 08:07:50 +0000494- Patch #1506645: add Python wrappers for the curses functions
495 is_term_resized, resize_term and resizeterm.

499
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000500- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
501 functions.
502
Martin v. Löwis3798da02006-06-17 18:44:27 +0000503- Patch #812986: Update turtle output even if not tracing.
504
Vinay Sajip28e57612006-07-01 10:45:20 +0000505- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000506 Tkinter.BaseWidget.
507
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000508- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
509
Martin v. Löwis337487e2006-06-17 09:15:14 +0000510- Patch #763580: Add name and value arguments to Tkinter variable
511 classes.
512
Georg Brandl83cc0d02006-06-14 08:50:03 +0000513- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
514 mime.types file for determining MIME types.
515
Georg Brandl2605ca82006-06-14 06:08:31 +0000516- Bug #1339007: Shelf objects now don't raise an exception in their
517 __del__ method when initialization failed.
518
Martin v. Löwisd8251432006-06-14 05:21:04 +0000519- Patch #1455898: The MBCS codec now supports the incremental mode for
520 double-byte encodings.
521
Tim Peters43898b42006-06-14 04:09:25 +0000522- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
523 guarantee that adjacent triples in the return list always describe
524 non-adjacent blocks. Previously, a pair of matching blocks could end
525 up being described by multiple adjacent triples that formed a partition
526 of the matching pair.
527
Greg Ward0e0c9f42006-06-11 16:24:11 +0000528- Bug #1498146: fix optparse to handle Unicode strings in option help,
529 description, and epilog.
530
Greg Wardd1c797e2006-06-11 14:42:41 +0000531- Bug #1366250: minor optparse documentation error.
532
Greg Ward7f547402006-06-11 00:40:49 +0000533- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
534 clarify docs.
535
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000536- The wsgiref package has been added to the standard library.
537
Nick Coghlan676725d2006-06-08 13:54:49 +0000538- The functions update_wrapper() and wraps() have been added to the functools
539 module. These make it easier to copy relevant metadata from the original
540 function when writing wrapper functions.
541
Tim Petersd6a9eef2006-06-05 01:48:21 +0000542- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
543 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000544
Martin v. Löwis3f767792006-06-04 19:36:28 +0000545- Patch #1359618: Speed up charmap encoder by using a trie structure
546 for lookup.
547
Tim Petersd609b1a2006-06-02 23:22:51 +0000548- The functions in the ``pprint`` module now sort dictionaries by key
549 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
550 if and only if its display required more than one line, although that
551 wasn't documented. The new behavior increases predictability; e.g.,
552 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
553
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000554- Patch #1497027: try HTTP digest auth before basic auth in urllib2
555 (thanks for J. J. Lee).
556
Georg Brandl2b330372006-05-28 20:23:12 +0000557- Patch #1496206: improve urllib2 handling of passwords with respect to
558 default HTTP and HTTPS ports.
559
George Yoshidaf3c65de2006-05-28 16:39:09 +0000560- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
561
Bob Ippolito7298f272006-05-23 18:43:47 +0000562- Patch #1281707: speed up gzip.readline.
563
Georg Brandlb89316f2006-05-17 15:51:16 +0000564- Patch #1180296: Two new functions were added to the locale module:
565 format_string() to get the effect of "format % items" but locale-aware,
566 and currency() to format a monetary number with currency sign.
567
Georg Brandle3a25832006-05-17 14:56:04 +0000568- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
569 and several features added, such as speed and geometry control.
570
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000571- Patch #1488881: add support for external file objects in bz2 compressed
572 tarfiles.
573
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000574- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
575 stdout arguments, making it possible to redirect input and output
576 for remote debugging.
577
578- Patch #1484695: Update the tarfile module to version 0.8. This fixes
579 a couple of issues, notably handling of long file names using the
580 GNU LONGNAME extension.
581
582- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
583 new flag when ``name`` is already the name of an option flag.
584
585- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
586 package.
587

Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000593- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000624What's New in Python 2.5 alpha 2?
625=================================
626
627*Release date: 27-APR-2006*
628
629Core and builtins
630-----------------
631
Thomas Heller1b046642006-04-18 18:51:06 +0000632- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
633 by converting these apis from macros into exported functions again:
634
635 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
636 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
637 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
638 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
639 PyRun_String Py_CompileString
640
Martin v. Löwis45294a92006-04-18 06:24:08 +0000641- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
642
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000643- All uses of PyStructSequence_InitType have been changed to initialize
644 the type objects only once, even if the interpreter is initialized
645 multiple times.
646
Neal Norwitz61546162006-04-14 05:20:28 +0000647- Bug #1454485, array.array('u') could crash the interpreter. This was
648 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
649 to unicode when it didn't make sense. 'u#' now requires a unicode string.
650
651- Py_UNICODE is unsigned. It was always documented as unsigned, but
652 due to a bug had a signed value in previous versions.
653
Tim Peters3a5e8b12006-04-11 01:44:07 +0000654- Patch #837242: ``id()`` of any Python object always gives a positive
655 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
656 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000657 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000658 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000659
Tim Peters3a5e8b12006-04-11 01:44:07 +0000660 def __hash__(self):
661 return id(self) # WRONG
662
663 because a hash result must be a (short) Python int but it was always
664 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000665 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000666 was always usable as a hash value before this patch. That's no longer
667 necessarily so.
668
669- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000670 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000671 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000672 #1454844)
673
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000674- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
675 involving generators that have paused outside of any ``try`` or ``with``
676 blocks. (In 2.5a1, a paused generator that was part of a reference
677 cycle could not be garbage collected, regardless of whether it was
678 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +0000679
Anthony Baxter51bcb682006-04-05 14:51:42 +0000680Extension Modules
681-----------------
682
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000683- Patch #1191065: Fix preprocessor problems on systems where recvfrom
684 is a macro.
685
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000686- Bug #1467952: os.listdir() now correctly raises an error if readdir()
687 fails with an error condition.
688
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000689- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
690
691- Bug #1117761: bsddb.*open() no longer raises an exception when using
692 the cachesize parameter.
693
694- Bug #1149413: bsddb.*open() no longer raises an exception when using
695 a temporary db (file=None) with the 'n' flag to truncate on open.
696
697- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
698 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000699
Armin Rigoa9017c32006-04-19 11:50:27 +0000700- Patch #1062014: AF_UNIX sockets under Linux have a special
701 abstract namespace that is now fully supported.
702
Anthony Baxter51bcb682006-04-05 14:51:42 +0000703Library
704-------
705
Peter Astrand7d1d4362006-07-14 14:04:45 +0000706- Bug #1223937: subprocess.CalledProcessError reports the exit status
707 of the process using the returncode attribute, instead of
708 abusing errno.
709
Tim Peters711bf302006-04-25 03:31:36 +0000710- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
711 a doctest to be skipped (the code is not run, and the expected output
712 or exception is ignored).
713
Nick Coghlanda2268f2006-04-24 04:37:15 +0000714- Fixed contextlib.nested to cope with exceptions being raised and
715 caught inside exit handlers.
716
Greg Wardab05edc2006-04-23 03:47:58 +0000717- Updated optparse module to Optik 1.5.1 (allow numeric constants in
718 hex, octal, or binary; add ``append_const`` action; keep going if
719 gettext cannot be imported; added ``OptionParser.destroy()`` method;
720 added ``epilog`` for better help generation).
721
Tim Peters21fbd572006-04-21 21:18:10 +0000722- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
723 called from a thread spawned as a side effect of importing a module.
724
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000725- The pydoc module now supports documenting packages contained in
726 .zip or .egg files.
727
728- The pkgutil module now has several new utility functions, such
729 as ``walk_packages()`` to support working with packages that are either
730 in the filesystem or zip files.
731
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000732- The mailbox module can now modify and delete messages from
733 mailboxes, in addition to simply reading them. Thanks to Gregory
734 K. Johnson for writing the code, and to the 2005 Google Summer of
735 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000736
Tim Petersc7605f22006-04-17 21:12:33 +0000737- The ``__del__`` method of class ``local`` in module ``_threading_local``
738 returned before accomplishing any of its intended cleanup.
739
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000740- Patch #790710: Add breakpoint command lists in pdb.
741
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000742- Patch #1063914: Add Tkinter.Misc.clipboard_get().
743
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000744- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
745
Anthony Baxtere29002c2006-04-12 12:07:31 +0000746- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
747 Windows. Bug #1469163.
748
Phillip J. Eby47032112006-04-11 01:07:43 +0000749- The warnings, linecache, inspect, traceback, site, and doctest modules
750 were updated to work correctly with modules imported from zipfiles or
751 via other PEP 302 __loader__ objects.
752
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000753- Patch #1467770: Reduce usage of subprocess._active to processes which
754 the application hasn't waited on.
755
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000756- Patch #1462222: Fix Tix.Grid.
757
Neal Norwitza31bf182006-04-09 03:35:43 +0000758- Fix exception when doing glob.glob('anything*/')
759
Skip Montanaro262fb922006-04-21 02:31:07 +0000760- The pstats.Stats class accepts an optional stream keyword argument to
761 direct output to an alternate file-like object.
762
Anthony Baxter51bcb682006-04-05 14:51:42 +0000763Build
764-----
765
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000766- The Makefile now has a reindent target, which runs reindent.py on
767 the library.
768
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000769- Patch #1470875: Building Python with MS Free Compiler
770
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000771- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000772
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000773- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
774 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000775 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000776 CXX from --with-cxx-main, see description in README.
777
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000778- Patch #1429775: Link extension modules with the shared libpython.
779
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000780- Fixed a libffi build problem on MIPS systems.
781
Tim Peters8931ff12006-05-13 23:28:20 +0000782- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
783 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
784 and "%zu" for unsigned integers of type ``size_t``.
785
Anthony Baxter51bcb682006-04-05 14:51:42 +0000786Tests
787-----
788
Nick Coghlanda2268f2006-04-24 04:37:15 +0000789- test_contextlib now checks contextlib.nested can cope with exceptions
790 being raised and caught inside exit handlers.
791
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000792- test_cmd_line now checks operation of the -m and -c command switches
793
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000794- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
795 it separately and by hand. It also wasn't cleaning up its changes to
796 the current Decimal context.
797
Thomas Woutersabd08882006-04-26 15:53:30 +0000798- regrtest.py now has a -M option to run tests that test the new limits of
799 containers, on 64-bit architectures. Running these tests is only sensible
800 on 64-bit machines with more than two gigabytes of memory. The argument
801 passed is the maximum amount of memory for the tests to use.
802
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +0000803Tools
804-----
805
806- Added the Python benchmark suite pybench to the Tools/ directory;
807 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000808
Anthony Baxter51bcb682006-04-05 14:51:42 +0000809Documentation
810-------------
811
Tim Petersb06d28c2006-05-12 01:57:59 +0000812- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
813
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000814- PEP 343: Added Context Types section to the library reference
815 and attempted to bring other PEP 343 related documentation into
816 line with the implementation and/or python-dev discussions.
817
Tim Peters8dc73d22006-04-24 02:03:16 +0000818- Bug #1337990: clarified that ``doctest`` does not support examples
819 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +0000820
821
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000822What's New in Python 2.5 alpha 1?
823=================================
824
Anthony Baxterebed3f62006-04-03 15:03:44 +0000825*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000826
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000827Core and builtins
828-----------------
829
Nick Coghlan43832302006-04-23 17:04:07 +0000830- PEP 338: -m command line switch now delegates to runpy.run_module
831 allowing it to support modules in packages and zipfiles
832
Martin v. Löwisc661b882006-04-20 04:54:23 +0000833- On Windows, .DLL is not an accepted file name extension for
834 extension modules anymore; extensions are only found if they
835 end in .PYD.
836
Martin v. Löwisea62d252006-04-03 10:56:49 +0000837- Bug #1421664: sys.stderr.encoding is now set to the same value as
838 sys.stdout.encoding.
839
Neal Norwitz92e212f2006-04-03 04:48:37 +0000840- __import__ accepts keyword arguments.
841
Georg Brandlccadf842006-03-31 18:54:53 +0000842- Patch #1460496: round() now accepts keyword arguments.
843
Anthony Baxter262c00a2006-03-30 10:53:17 +0000844- Fixed bug #1459029 - unicode reprs were double-escaped.
845
Hye-Shik Changd478f342006-03-23 12:32:36 +0000846- Patch #1396919: The system scope threads are reenabled on FreeBSD
847 5.4 and later versions.
848
Neal Norwitze98ccf62006-03-23 05:39:47 +0000849- Bug #1115379: Compiling a Unicode string with an encoding declaration
850 now gives a SyntaxError.
851
Georg Brandlabd1ff82006-03-18 07:59:59 +0000852- Previously, Python code had no easy way to access the contents of a
853 cell object. Now, a ``cell_contents`` attribute has been added
854 (closes patch #1170323).
855
Tim Peterscf79aac2006-03-16 01:14:46 +0000856- Patch #1123430: Python's small-object allocator now returns an arena to
857 the system ``free()`` when all memory within an arena becomes unused
858 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
859 freed. Some applications will see a drop in virtual memory size now,
860 especially long-running applications that, from time to time, temporarily
861 use a large number of small objects. Note that when Python returns an
862 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000863 platform C library will in turn return that memory to the operating system.
864 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000865 appears to be effective at least on Microsoft C and gcc-based systems.
866 Thanks to Evan Jones for hard work and patience.
867
Georg Brandl533ff6f2006-03-08 18:09:27 +0000868- Patch #1434038: property() now uses the getter's docstring if there is
869 no "doc" argument given. This makes it possible to legitimately use
870 property() as a decorator to produce a read-only property.
871
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000872- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
873 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
874 of requiring an int or long in slicing and a few other contexts, enabling
875 other objects (e.g. Numeric Python's integers) to be used as slice indices.
876
Neal Norwitz995acdf2006-03-07 05:01:00 +0000877- Fixed various bugs reported by Coverity's Prevent tool.
878
Brett Cannonbf364092006-03-01 04:25:17 +0000879- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
880 new exception base class, BaseException, which has a new message attribute.
881 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
882 Raising a string exception now raises a DeprecationWarning.
883
Thomas Woutersfb609f42006-02-28 16:37:25 +0000884- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
885 explicitly relative, using 'from .module import name' to mean 'from the same
886 package as this module is in. Imports without dots still default to the
887 old relative-then-absolute, unless 'from __future__ import
888 absolute_import' is used.
889
Brett Cannona7446e32006-02-27 23:39:10 +0000890- Properly check if 'warnings' raises an exception (usually when a filter set
891 to "error" is triggered) when raising a warning for raising string
892 exceptions.
893
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000894- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000895 The name was removed from Include/code.h.
896
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000897- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000898
Guido van Rossum1968ad32006-02-25 22:38:04 +0000899- Patch 1433928:
900 - The copy module now "copies" function objects (as atomic objects).
901 - dict.__getitem__ now looks for a __missing__ hook before raising
902 KeyError.
903
Tim Peters84ef21c2006-02-28 20:39:06 +0000904- PEP 343: with statement implemented. Needs ``from __future__ import
905 with_statement``. Use of 'with' as a variable will generate a warning.
906 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000907 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000908 The following objects have __context__ methods:
909 - The built-in file type.
910 - The thread.LockType type.
911 - The following types defined by the threading module:
912 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
913 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000914
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000915- Fix the encodings package codec search function to only search
916 inside its own package. Fixes problem reported in patch #1433198.
917
918 Note: Codec packages should implement and register their own
919 codec search function. PEP 100 has the details.
920
Tim Peters9ea89d22006-06-04 03:26:02 +0000921- PEP 353: Using ``Py_ssize_t`` as the index type.
922
923- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
924 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
925 now allow Python to make use of memory blocks exceeding 2**32 bytes for
926 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
927 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000928
Neal Norwitzfc76d632006-01-10 06:03:13 +0000929- Patch #1400181, fix unicode string formatting to not use the locale.
930 This is how string objects work. u'%f' could use , instead of .
931 for the decimal point. Now both strings and unicode always use periods.
932
Neal Norwitz671b9e32006-01-09 07:07:12 +0000933- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
934 configure would break checking curses.h.
935
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000936- Bug #959576: The pwd module is now builtin. This allows Python to be
937 built on UNIX platforms without $HOME set.
938
Neal Norwitzc10978f2005-12-19 06:07:16 +0000939- Bug #1072182, fix some potential problems if characters are signed.
940
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000941- Bug #889500, fix line number on SyntaxWarning for global declarations.
942
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000943- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
944
Neal Norwitze7214a12005-12-18 05:03:17 +0000945- Support for converting hex strings to floats no longer works.
946 This was not portable. float('0x3') now raises a ValueError.
947
Barry Warsaw2a38a862005-12-18 01:27:35 +0000948- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000949 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000950 is now displayed in interactive prompt banner.
951
Georg Brandlfa166682005-12-17 21:45:17 +0000952- Implementation of PEP 341 - Unification of try/except and try/finally.
953 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000954 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000955
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000956- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
957 now encodes backslash correctly.
958
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000959- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
960
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000961- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000962 and long longs.
963
Neal Norwitz67715f02005-11-09 06:59:35 +0000964- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000965 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000966 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000967
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000968- Replaced most Unicode charmap codecs with new ones using the
969 new Unicode translate string feature in the builtin charmap
970 codec; the codecs were created from the mapping tables available
971 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
972 encodings now include a mapping for the Apple logo)
973
Tim Peterse3547fd2005-12-16 23:13:57 +0000974- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000975
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000976- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000977
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000978- A new AST parser implementation was completed. The abstract
979 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000980 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000981
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000982- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000983 The following code now raises a SyntaxError: foo(a = i for i in range(10))
984
Neal Norwitz708e51a2005-10-03 04:48:15 +0000985- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
986
Neal Norwitz11bd1192005-10-03 00:54:56 +0000987- SF Bug #887946: fix segfault when redirecting stdin from a directory.
988 Provide a warning when a directory is passed on the command line.
989
Neal Norwitz40d37812005-10-02 01:48:49 +0000990- Fix segfault with invalid coding.
991
992- SF bug #772896: unknown encoding results in MemoryError.
993
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000994- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000995 supported a __len__() method which evaluated to False when the iterator
996 was empty.
997
Guido van Rossum630db602005-09-20 18:49:54 +0000998- On 64-bit platforms, when __len__() returns a value that cannot be
999 represented as a C int, raise OverflowError.
1000
Skip Montanarof8948ca2005-09-19 03:54:46 +00001001- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001002 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001003
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001004- SF bug #893549: parsing keyword arguments was broken with a few format
1005 codes.
1006
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001007- Changes donated by Elemental Security to make it work on AIX 5.3
1008 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1009 bug #105470: test_pwd fails on 64bit system (Opteron).
1010
Guido van Rossum539c6622005-09-14 17:49:54 +00001011- Changes donated by Elemental Security to make it work on HP-UX 11 on
1012 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1013
Georg Brandl4550b8d2005-08-26 06:43:52 +00001014- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001015 (fixes bug #1119418).
1016
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001017- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1018
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001019- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1020 exceptions that cause a function to exit.
1021
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001022- The implementation of set() and frozenset() was revised to use its
1023 own internal data structure. Memory consumption is reduced by 1/3
1024 and there are modest speed-ups as well. The API is unchanged.
1025
Tim Petersde7990b2005-07-17 23:45:23 +00001026- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1027
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001028- SF bug #1229429: PyObject_CallMethod failed to decrement some
1029 reference counts in some error exit cases.
1030
Tim Petersecc6e6a2005-07-10 22:30:55 +00001031- SF bug #1185883: Python's small-object memory allocator took over
1032 a block managed by the platform C library whenever a realloc specified
1033 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001034 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001035 portable way to copy data from the C-managed block into Python's
1036 small-object space without risking a memory fault. Python's small-object
1037 realloc now leaves such blocks under the control of the platform C
1038 realloc.
1039
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001040- SF bug #1232517: An overflow error was not detected properly when
1041 attempting to convert a large float to an int in os.utime().
1042
Raymond Hettinger3296e692005-06-29 23:29:56 +00001043- SF bug #1224347: hex longs now print with lowercase letters just
1044 like their int counterparts.
1045
Michael W. Hudson188d4362005-06-20 16:52:57 +00001046- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1047 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1048 interpreter states; back out that fix and do a better job (see
1049 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1050 for a longer write-up of the problem).
1051
Michael W. Hudsondf888462005-06-03 14:41:55 +00001052- SF patch #1180995: marshal now uses a binary format by default when
1053 serializing floats.
1054
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001055- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1056 the routines that promise to produce IEEE 754 binary representations
1057 of floats now simply copy bytes around.
1058
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001059- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1060 278.
1061
Brett Cannonc3647ac2005-04-26 03:45:26 +00001062- patch #1109424: int, long, float, complex, and unicode now check for the
1063 proper magic slot for type conversions when subclassed. Previously the
1064 magic slot was ignored during conversion. Semantics now match the way
1065 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001066 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001067 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001068 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001069
Barry Warsawc8d907c2005-04-19 23:43:40 +00001070- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1071 NULL, now raise an AttributeError when attempting to set or delete the
1072 attribute. Previously a TypeError was raised, but this was inconsistent
1073 with the equivalent pure-Python implementation.
1074
Michael W. Hudson774479c2005-04-18 08:46:17 +00001075- It is now safe to call PyGILState_Release() before
1076 PyEval_InitThreads() (note that if there is reason to believe there
1077 are multiple threads around you still must call PyEval_InitThreads()
1078 before using the Python API; this fix is for extension modules that
1079 have no way of knowing if Python is multi-threaded yet).
1080
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001081- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1082 disabled caused a crash.
1083
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001084- Bug #1165306: instancemethod_new allowed the creation of a method
1085 with im_class == im_self == NULL, which caused a crash when called.
1086
Tim Petersecc6e6a2005-07-10 22:30:55 +00001087- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001088 fixes the crash seen in bug #1165761
1089
Raymond Hettinger96229b12005-03-11 06:49:40 +00001090- Added two new builtins, any() and all().
1091
Brett Cannon409d8f22005-03-05 06:47:57 +00001092- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001093 (e.g., ``class C(): pass`` is no longer a syntax error).
1094 Patch #1176012 added support to the 'parser' module and 'compiler' package
1095 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001096
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001097- Patch #1115086: Support PY_LONGLONG in structmember.
1098
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001099- Bug #1155938: new style classes did not check that __init__() was
1100 returning None.
1101
Tim Petersecc6e6a2005-07-10 22:30:55 +00001102- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001103 ('\') with a specific error message.
1104
Martin v. Löwisff232d72005-03-03 09:24:38 +00001105- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1106
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001107- Bug #1124295: the __name__ attribute of file objects was
1108 inadvertently made inaccessible in restricted mode.
1109
Tim Petersecc6e6a2005-07-10 22:30:55 +00001110- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001111 an ferror() call.
1112
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001113- min() and max() now support key= arguments with the same meaning as in
1114 list.sort().
1115
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001116- The peephole optimizer now performs simple constant folding in expressions:
1117 (2+3) --> (5).
1118
Raymond Hettingera422c342005-01-11 03:03:27 +00001119- set and frozenset objects can now be marshalled. SF #1098985.
1120
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001121- Bug #1077106: Poor argument checking could cause memory corruption
1122 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001123
Jeremy Hyltonab630502005-02-04 18:44:06 +00001124- The parser did not complain about future statements in illegal
1125 positions. It once again reports a syntax error if a future
1126 statement occurs after anything other than a doc string.
1127
Neil Schemenauercf52c072005-08-12 17:34:58 +00001128- Change the %s format specifier for str objects so that it returns a
1129 unicode instance if the argument is not an instance of basestring and
1130 calling __str__ on the argument returns a unicode instance.
1131
Tim Petersf4e69282006-02-27 17:15:31 +00001132- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1133 current thread state when the auto-GIL-state machinery knows about
1134 it (since the thread state is being deleted, continuing to remember it
1135 can't help, but can hurt if another thread happens to get created with
1136 the same thread id).
1137
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001138Extension Modules
1139-----------------
1140
Georg Brandl43f08a82006-03-31 18:01:16 +00001141- Patch #1380952: fix SSL objects timing out on consecutive read()s

1144
Anthony Baxterfa869072006-03-20 05:21:58 +00001145- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1146 In addition, the existing ulaw code was updated.
1147
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001148- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001149 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001150
Neal Norwitz10be10c2006-03-16 06:50:13 +00001151- Everything under lib-old was removed. This includes the following modules:
1152 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001153 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001154 util, whatsound, whrandom, zmod
1155
1156- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1157
1158- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001159 is deprecated. The undocumented re.engine variable no longer exists.
1160
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001161- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1162 SS2 (single-shift 2) escape sequences correctly.
1163
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001164- The unicodedata module was updated to the 4.1 version of the Unicode
1165 database. The 3.2 version is still available as unicodedata.db_3_2_0
1166 for applications that require this specific version (such as IDNA).
1167
Neal Norwitzb62c4332006-03-04 18:35:47 +00001168- The timing module is no longer built by default. It was deprecated
1169 in PEP 4 in Python 2.0 or earlier.
1170
Guido van Rossum1968ad32006-02-25 22:38:04 +00001171- Patch 1433928: Added a new type, defaultdict, to the collections module.
1172 This uses the new __missing__ hook behavior added to dict (see above).
1173
Georg Brandldbd83392006-02-20 09:42:33 +00001174- Bug #854823: socketmodule now builds on Sun platforms even when
1175 INET_ADDRSTRLEN is not defined.
1176
Georg Brandlf4f44152006-02-18 22:29:33 +00001177- Patch #1393157: os.startfile() now has an optional argument to specify
1178 a "command verb" to invoke on the file.
1179
Neal Norwitz082b2df2006-02-07 07:04:46 +00001180- Bug #876637, prevent stack corruption when socket descriptor
1181 is larger than FD_SETSIZE.
1182
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001183- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1184 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1185 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1186
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001187- Patch #1422385: The nis module now supports access to domains other

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001328- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1329 been renamed to have only a single underscore prefix. This was done to
1330 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001331
Nick Coghlan43832302006-04-23 17:04:07 +00001332- PEP 338: new module runpy defines a run_module function to support
1333 executing modules which provide access to source code or a code object
1334 via the PEP 302 import mechanisms.
1335
Anthony Baxter93f5b932006-04-03 08:05:07 +00001336- The email module's parsedate_tz function now sets the daylight savings

1344 in attribute values.
1345
Anthony Baxterc51ee692006-04-01 00:57:31 +00001346- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001347 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001348 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001349 module will not be built.
1350
Tim Petersc17976e2006-04-01 00:26:53 +00001351- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1352 aren't officially supported here, and trying to use them will probably
1353 raise an exception some day. But dicts have been allowed, and "mostly
1354 worked", so support for them won't go away without warning.
1355
Georg Brandl338ef7d2006-03-31 18:42:16 +00001356- Bug #1445068: getpass.getpass() can now be given an explicit stream
1357 argument to specify where to write the prompt.
1358

1374
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001375- email 4.0 package now integrated. This is largely the same as the email 3.0
1376 package that was included in Python 2.3, except that PEP 8 module names are
1377 now used (e.g. mail.message instead of email.Message). The MIME classes
1378 have been moved to a subpackage (e.g. email.mime.text instead of
1379 email.MIMEText). The old names are still supported for now. Several
1380 deprecated Message methods have been removed and lots of bugs have been
1381 fixed. More details can be found in the email package documentation.
1382
Walter Dörwald40108c92006-03-27 08:15:44 +00001383- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1384 (a subclass of tuple) that provides incremental decoders and encoders
1385 (a way to use stateful codecs without the stream API). Python functions
1386 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1387 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1388 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001390- Patch #1359365: Calling next() on a closed StringIO.String object raises
1391 a ValueError instead of a StopIteration now (like file and cString.String do).
1392 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1393 called before (like file and StringIO.StringIO do).

1461
Neal Norwitz338e7862005-12-23 21:27:46 +00001462- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1463 LoadError as documented, instead of IOError. For compatibility,
1464 LoadError subclasses IOError.
1465
Brett Cannon3cbd0382005-12-16 22:49:23 +00001466- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001467 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1468 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1469 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1470 Ronald L. Rivest offered this advice for Python:
1471
1472 "The consensus of researchers in this area (at least as
1473 expressed at the NIST Hash Function Workshop 10/31/05),
1474 is that SHA-256 is a good choice for the time being, but
1475 that research should continue, and other alternatives may
1476 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001477
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001478- Added a subset of Fredrik Lundh's ElementTree package. Available

1531 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001532 correct line numbers for decoding errors in source code.

1571 Bug #1224621.
1572
Raymond Hettinger68c04532005-06-10 11:05:19 +00001573- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001574 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001575 the generate_tokens() function now accepts a callable argument that
1576 terminates by raising StopIteration.
1577
Georg Brandl9166e1a2005-06-04 09:20:03 +00001578- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1582
Skip Montanaro174dd222005-05-14 20:54:16 +00001583- Patch #1120353: The xmlrpclib module provides better, more transparent,

1586 class at all.
1587
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001588- distutils.commands.upload was added to support uploading distribution

1592 them to PyPI.
1593
Raymond Hettinger267b8682005-03-27 10:47:39 +00001594- decimal operator and comparison methods now return NotImplemented
1595 instead of raising a TypeError when interacting with other types. This
1596 allows other classes to implement __radd__ style methods and have them
1597 work as expected.
1598
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001599- Bug #1163325: Decimal infinities failed to hash. Attempting to

1601
Tim Petersecc6e6a2005-07-10 22:30:55 +00001602- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1636
Guido van Rossumd0641422005-02-03 15:01:24 +00001637- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1638 disables recursive traversal through instance attributes, which can
1639 be exploited in various ways.
1640
Tim Peterse3547fd2005-12-16 23:13:57 +00001641- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001642 flags on the HTTP listening socket.
1643

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001652- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1653
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001654- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1655
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001656- Enhancements to the csv module:
1657
1658 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001659 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001660 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001661 + Dialect parameter parsing has been re-implemented to improve error
1662 reporting.
1663 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1664 dictates.
1665 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001666 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001667 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001668 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1669 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001670 + reader now allows \r characters to be quoted (previously it only allowed
1671 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001672 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001673 + Dialect classes passed to the module are no longer instantiated by
1674 the module before being parsed (the former validation scheme required
1675 this, but the mechanism was unreliable).
1676 + The dialect registry now contains instances of the internal
1677 C-coded dialect type, rather than references to python objects.
1678 + the internal c-coded dialect type is now immutable.
1679 + register_dialect now accepts the same keyword dialect specifications
1680 as the reader and writer, allowing the user to register dialects
1681 without first creating a dialect class.
1682 + a configurable limit to the size of parsed fields has been added -
1683 previously, an unmatched quote character could result in the entire
1684 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001685 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001686 the parser field size limit (returning the former limit). The initial
1687 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001688 + A line_num attribute has been added to the reader object, which tracks
1689 the number of lines read from the source iterator. This is not
1690 the same as the number of records returned, as records can span
1691 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001692 + reader and writer objects were not being registered with the cyclic-GC.
1693 This has been fixed.
1694
Brett Cannone6539c42005-01-08 02:43:53 +00001695- _DummyThread objects in the threading module now delete self.__block that is
1696 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1697 lock primitives tend to be limited in number and thus should not be wasted on
1698 a _DummyThread object. Fixes bug #1089632.
1699
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001700- The imghdr module now detects Exif files.
1701
Raymond Hettinger6065d322004-12-20 23:51:53 +00001702- StringIO.truncate() now correctly adjusts the size attribute.
1703 (Bug #951915).
1704
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001705- locale.py now uses an updated locale alias table (built using
1706 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1707 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001708 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001709
Raymond Hettinger3557f422004-12-07 12:02:02 +00001710- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1711
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001712- the pickle module no longer accepts the deprecated None option in the
1713 args tuple returned by __reduce__().
1714
Brett Cannon84667c02004-12-07 03:25:18 +00001715- optparse now optionally imports gettext. This allows its use in setup.py.
1716
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001717- the pickle module no longer uses the deprecated bin parameter.

1724
Raymond Hettinger664347b2004-12-04 21:21:53 +00001725- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1726 extended or overridden by subclasses. Formerly, the subclassed method would
1727 be ignored by the rest of the module. (Bug #1078905).
1728
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001729- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001730 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001731
Walter Dörwald36733692004-12-22 12:50:50 +00001732- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1733 once when a size argument is given. This prevents a buffer overflow in the
1734 tokenizer with very long source lines.
1735
Barry Warsaw538561e2006-01-01 21:48:54 +00001736- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1737 immediately after creating the object, without any intervening
1738 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001739
Skip Montanaro05885812005-01-16 20:48:27 +00001740- The reconvert.quote function can now emit triple-quoted strings. The
1741 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001742
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001743- ``UserString.MutableString`` now supports negative indices in
1744 ``__setitem__`` and ``__delitem__``
1745
Greg Ward40407942005-03-05 02:53:17 +00001746- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1747 correctly.
1748
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001749- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1750 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1751 character even if the user has passed a size parameter to get a proper
1752 line ending. Remove the special handling of a "\r\n" that has been split
1753 between two lines.
1754
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001755- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1756 about illegal code points. The codec now supports PEP 293 style error
1757 handlers.
1758
Walter Dörwald78a78b02005-09-01 12:04:29 +00001759- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001760 from the input stream, so that the output is a byte string in the correct
1761 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001762
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001763- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1764 considering it exactly like a '*'.
1765
Walter Dörwald007f8df2005-10-09 19:42:27 +00001766- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1767 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001768
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001769- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1770
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001771- Patch #1413711: Certain patterns of differences were making difflib
1772 touch the recursion limit.
1773
Walter Dörwald58917a62006-03-31 15:26:22 +00001774- Bug #947906: An object oriented interface has been added to the calendar
1775 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001776 called as a script (e.g. via ``python -mcalendar``). Localized month and
1777 weekday names can be ouput (even if an exotic encoding is used) using
1778 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001780Build
1781-----
1782
Neal Norwitz602d3392006-03-31 08:21:40 +00001783- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1784 by using -mieee gcc option.
1785

1787
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001788- Build support for Win64-AMD64 was added.
1789
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001790- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1791
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001792- Patch #881820: look for openpty and forkpty also in libbsd.
1793
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001794- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1795 The zlib module is now builtin on Windows.
1796
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001797- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1798
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001799- Bug #1189330: configure did not correctly determine the necessary
1800 value of LINKCC if python was built with GCC 4.0.
1801
Trent Mick8321b422005-07-26 02:29:21 +00001802- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1803 vulnerability in zlib 1.2.1 and 1.2.2.
1804
Brett Cannon08cd5982005-04-24 22:26:38 +00001805- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1806 flags that change binary compatibility. Changes were also made to
1807 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001808 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001809
Bob Ippolitoed233462005-03-29 13:47:59 +00001810- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1811 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1812 no longer exists). This configure patch makes things right.
1813
Martin v. Löwise2713be2005-03-08 15:03:08 +00001814- Bug #1158607: Build with --disable-unicode again.
1815
Brett Cannon46d96232005-02-16 00:07:19 +00001816- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1817 defined. Discovered as a result of not being able to build on OS X.
1818
Brett Cannon516592f2004-12-07 00:42:59 +00001819- setup.py now uses the directories specified in LDFLAGS using the -L option
1820 and in CPPFLAGS using the -I option for adding library and include
1821 directories, respectively, for compiling extension modules against. This has
1822 led to the core being compiled using the values in CPPFLAGS. It also removes
1823 the need for the special-casing of both DarwinPorts and Fink for darwin since
1824 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1825 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1826 Fink, ``-I/opt/local/include`` for DarwinPorts).
1827
Brett Cannon43802422005-02-10 20:48:03 +00001828- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1829 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1830 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1831 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001833C API
1834-----
1835
Tim Petersc9d78aa2006-03-26 23:27:58 +00001836- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1837 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1838 is obtained via the ``PyObject_`` family, it must be released via the
1839 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1840 always been officially true, but when Python's small-object allocator was
1841 introduced, an attempt was made to cater to a few extension modules
1842 discovered at the time that obtained memory via ``PyObject_New`` but
1843 released it via ``PyMem_DEL``. It's years later, and if such code still
1844 exists it will fail now (probably with segfaults, but calling wrong
1845 low-level memory management functions can yield many symptoms).
1846
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001847- Added a C API for set and frozenset objects.
1848
Raymond Hettinger66517482004-12-03 11:45:13 +00001849- Removed PyRange_New().
1850
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001851- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1852 mapping argument now. This string is used as a mapping table. Byte values
1853 greater than the length of the string and 0xFFFE are treated as undefined
1854 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001861
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001862- Patch #1276356: New resource "urlfetch" is implemented. This enables
1863 even impatient people to run tests that require remote files.
