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 Norwitz07aadb12006-07-30 06:55:48 +000015- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
16 This provides the proper warning for struct.pack().
17 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
18
Neal Norwitz0d62a062006-07-30 06:53:31 +000019- Patch #1531113: Fix augmented assignment with yield expressions.
20 Also fix a SystemError when trying to assign to yield expressions.
21
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000022- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
23 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
24 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
25 excessive filesystem operations during imports.
26
Tim Petersbc24eee2006-07-27 01:14:53 +000027- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
28 operations on signed longs that are formally undefined by C.
29 Unfortunately, at least one compiler now cares about that, so complicated
30 the code to make that compiler happy again.
31
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000032- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
33
Martin v. Löwisd22968a2006-07-24 11:54:53 +000034- Patch #1232023: Stop including current directory in search
35 path on Windows.
36
Neal Norwitze1fdb322006-07-21 05:32:28 +000037- Fix some potential crashes found with failmalloc.
38
Neal Norwitze7563102006-07-17 01:00:16 +000039- Fix warnings reported by Klocwork's static analysis tool.
40
Neal Norwitz84be93b2006-07-16 01:50:38 +000041- Bug #1512814, Fix incorrect lineno's when code within a function
42 had more than 255 blank lines.
43
Georg Brandl9dceedb2006-07-12 15:31:17 +000044- Patch #1521179: Python now accepts the standard options ``--help`` and
45 ``--version`` as well as ``/?`` on Windows.
46
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000047- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000048 again. Fixing this problem required changing the .pyc magic number.
49 This means that .pyc files generated before 2.5c1 will be regenerated.
50
Tim Peters112aad32006-07-19 00:03:19 +000051- Bug #1524317: Compiling Python ``--without-threads`` failed.
52 The Python core compiles again then, and, in a build without threads, the
53 new ``sys._current_frames()`` returns a dictionary with one entry,
54 mapping the faux "thread id" 0 to the current frame.
55
Ronald Oussoren3075e162006-07-25 20:28:55 +000056- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000057
Ronald Oussoren3075e162006-07-25 20:28:55 +000058
Neal Norwitza1f10902006-07-12 07:28:29 +000059Library
60-------
61
Fred Drakefbdeaad2006-07-29 16:56:15 +000062- Rename of the xml package to xmlcore, and the import hackery done to
63 make it appear at both names, has been removed. Bug #1511497,
64 #1513611, and probably others.
65
Georg Brandledd9b0d2006-07-29 09:33:26 +000066- Bug #1441397: The compiler module now recognizes module and function
67 docstrings correctly as it did in Python 2.4.
68
Tim Peters6f681472006-07-27 23:44:37 +000069- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
70 lost that tests are sorted by name before being run. This rarely
71 matters for well-written tests, but can create baffling symptoms if
72 side effects from one test to the next affect outcomes. ``DocTestFinder``
73 has been changed to sort the list of tests it returns.
74
Martin v. Löwis997ceff2006-07-27 06:38:16 +000075- The distutils version has been changed to 2.5.0.
76
Martin v. Löwis9298eff2006-07-26 12:12:56 +000077- Bug #978833: Really close underlying socket in _socketobject.close.
78
Georg Brandl0619a322006-07-26 07:40:17 +000079- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
80 with title().
81
Georg Brandlcf0c1722006-07-26 07:23:32 +000082- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
83 to recursive calls and call it with the failing package name.
84
Martin v. Löwis0b483032006-07-25 09:53:12 +000085- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
86
Georg Brandlc13c34c2006-07-24 14:09:56 +000087- Patch #1515343: Fix printing of deprecated string exceptions with a
88 value in the traceback module.
89
Greg Ward48fae7a2006-07-23 16:05:51 +000090- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
91
Martin v. Löwis426f4a12006-07-18 17:46:31 +000092- Patch #1524429: Use repr() instead of backticks in Tkinter again.
93
Brett Cannoncaebe222006-07-18 04:41:36 +000094- Bug #1520914: Change time.strftime() to accept a zero for any position in its
95 argument tuple. For arguments where zero is illegal, the value is forced to
96 the minimum value that is correct. This is to support an undocumented but
97 common way people used to fill in inconsequential information in the time
98 tuple pre-2.4.
99
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000100- Patch #1220874: Update the binhex module for Mach-O.
101
Barry Warsawb110bad2006-07-21 14:51:07 +0000102- The email package has improved RFC 2231 support, specifically for
103 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
104 (name*0=<blah>) parameter continuations. This may change the types of
105 values returned from email.message.Message.get_param() and friends.
106 Specifically in some cases where non-encoded continuations were used,
107 get_param() used to return a 3-tuple of (None, None, string) whereas now it
108 will just return the string (since non-encoded continuations don't have
109 charset and language parts).
110
111 Also, whereas % values were decoded in all parameter continuations, they are
112 now only decoded in encoded parameter parts.
113
Ronald Oussoren3075e162006-07-25 20:28:55 +0000114- Bug #1517990: IDLE keybindings on MacOS X now work correctly
115
116- Bug #1517996: IDLE now longer shows the default Tk menu when a
117 path browser, class browser or debugger is the frontmost window on MacOS X
118
Barry Warsaw00decd72006-07-27 23:43:15 +0000119- Patch #1520294: Support for getset and member descriptors in types.py,
120 inspect.py, and pydoc.py. Specifically, this allows for querying the type
121 of an object against these built-in types and more importantly, for getting
122 their docstrings printed in the interactive interpreter's help() function.
123
Ronald Oussoren3075e162006-07-25 20:28:55 +0000124
Neal Norwitza1f10902006-07-12 07:28:29 +0000125Extension Modules
126-----------------
127
Thomas Heller1393d6a2006-07-28 21:43:20 +0000128- Patch #1529514: The _ctypes extension is now compiled on more
129 openbsd target platforms.
130
Tim Peters9cab5932006-07-28 00:30:00 +0000131- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
132 a memory leak, affecting pickles and deep copies.
133
Tim Petersbc24eee2006-07-27 01:14:53 +0000134- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000135 Paul Eggert.
136

138
Thomas Hellerce049a02006-07-14 17:51:14 +0000139- Patch #1521817: Index range checking on ctypes arrays containing
140 exactly one element enabled again. This allows iterating over these
141 arrays, without the need to check the array size before.
142
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000143- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000144 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000145 /dev/null in certain cases; this is now fixed.
146
Thomas Heller47d7a062006-07-12 08:43:47 +0000147- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
148 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000149
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000150- Because of a misspelled preprocessor symbol, ctypes was always
151 compiled without thread support; this is now fixed.
152
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000153- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
154 methods now allow their database parameter to be None as the
155 sleepycat API allows.
156
Matt Flemingec926502006-07-28 11:27:27 +0000157- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
158 bluetooth API compared with Linux and FreeBSD.
159
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000160Tests
161-----
162
163- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
164 how long the test file should take to play. Now accepts taking 2.93 secs
165 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
166
Georg Brandl4793aa32006-07-28 18:31:39 +0000167- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
168 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
169 run via ``regrtest.py``. Now they do.

Georg Brandlad29e632006-06-21 17:45:17 +0000176
177Core and builtins
178-----------------
179
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000180- Bug #1441486: The literal representation of -(sys.maxint - 1)
181 again evaluates to a int object, not a long.
182
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000183- Bug #1501934: The scope of global variables that are locally assigned
184 using augmented assignment is now correctly determined.
185
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000186- Bug #927248: Recursive method-wrapper objects can now safely
187 be released.
188
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000189- Bug #1417699: Reject locale-specific decimal point in float()
190 and atof().
191
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000192- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
193 omit a default "error" argument for NULL pointer. This allows
194 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000195
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000196- Bug #1519018: 'as' is now validated properly in import statements.
197
Neal Norwitz28746ab2006-07-09 22:14:42 +0000198- On 64 bit systems, int literals that use less than 64 bits are
199 now ints rather than longs.
200
Neal Norwitzed657552006-07-10 00:04:44 +0000201- Bug #1512814, Fix incorrect lineno's when code at module scope
202 started after line 256.
203
Tim Peters32a83612006-07-10 21:08:24 +0000204- New function ``sys._current_frames()`` returns a dict mapping thread
205 id to topmost thread stack frame. This is for expert use, and is
206 especially useful for debugging application deadlocks. The functionality
207 was previously available in Fazal Majid's ``threadframe`` extension
208 module, but it wasn't possible to do this in a wholly threadsafe way from
209 an extension.
210
Georg Brandlad29e632006-06-21 17:45:17 +0000211Library
212-------
213

Tim Peters32a83612006-07-10 21:08:24 +0000216- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000217 environment variable to be set in order to the SDK environment
218 for finding the compiler, include files, etc.
219
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000220- Bug #1515998: Properly generate logical ids for files in bdist_msi.
221
Nick Coghlan2d792252006-07-06 13:47:18 +0000222- warnings.py now ignores ImportWarning by default
223
Thomas Woutersadd19112006-07-05 11:03:49 +0000224- string.Template() now correctly handles tuple-values. Previously,
225 multi-value tuples would raise an exception and single-value tuples would
226 be treated as the value they contain, instead.
227
Martin v. Löwisede77f52006-07-03 13:01:35 +0000228- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
229 even if some data are received.
230
Martin v. Löwis45482392006-07-03 12:28:58 +0000231- Bug #1267547: Put proper recursive setup.py call into the
232 spec file generated by bdist_rpm.

235 degrees and radians.
236
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000237- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000238 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000239
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000240- Bug #1514703: Only setup canvas window in turtle when the canvas
241 is created.
242
Martin v. Löwis7596e832006-07-01 15:33:37 +0000243- Bug #1513223: .close() of a _socketobj now releases the underlying

250 sgmllib ('[' and ']' were not accepted).
251
Georg Brandl1be63af2006-06-28 20:23:25 +0000252- Fix a bug in the turtle module's end_fill function.
253
Brett Cannon53ab5b72006-06-22 16:49:14 +0000254- Bug #1510580: The 'warnings' module improperly required that a Warning
255 category be either a types.ClassType and a subclass of Warning. The proper
256 check is just that it is a subclass with Warning as the documentation states.
257
Georg Brandlad29e632006-06-21 17:45:17 +0000258- The compiler module now correctly compiles the new try-except-finally
259 statement (bug #1509132).
260
Neal Norwitz60373cd2006-06-22 06:30:50 +0000261- The wsgiref package is now installed properly on Unix.
262
Vinay Sajip28e57612006-07-01 10:45:20 +0000263- A bug was fixed in logging.config.fileConfig() which caused a crash on
264 shutdown when fileConfig() was called multiple times.
265
Gerhard Häring762fbd32006-07-02 17:48:30 +0000266- The sqlite3 module did cut off data from the SQLite database at the first
267 null character before sending it to a custom converter. This has been fixed
268 now.
269
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000270Extension Modules
271-----------------
272
Tim Peters112aad32006-07-19 00:03:19 +0000273- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
274 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
275 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000276
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000277- Assigning None to pointer type fields in ctypes structures possible
278 overwrote the wrong fields, this is fixed now.
279
280- Fixed a segfault in _ctypes when ctypes.wintypes were imported
281 on non-Windows platforms.
282
283- Bug #1518190: The ctypes.c_void_p constructor now accepts any
284 integer or long, without range checking.
285
286- Patch #1517790: It is now possible to use custom objects in the ctypes
287 foreign function argtypes sequence as long as they provide a from_param
288 method, no longer is it required that the object is a ctypes type.
289
290- The '_ctypes' extension module now works when Python is configured
291 with the --without-threads option.
292
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000293- Bug #1513646: os.access on Windows now correctly determines write
294 access, again.
295
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000296- Bug #1512695: cPickle.loads could crash if it was interrupted with
297 a KeyboardInterrupt.
298
Neal Norwitza12aa882006-07-06 06:45:08 +0000299- Bug #1296433: parsing XML with a non-default encoding and
300 a CharacterDataHandler could crash the interpreter in pyexpat.
301
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000302- Patch #1516912: improve Modules support for OpenVMS.
303
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000304Build
305-----
306
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000307- Automate Windows build process for the Win64 SSL module.
308
Tim Peters32a83612006-07-10 21:08:24 +0000309- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000310 Previously, the slight difference could cause compilation errors of the

315
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000316- Bug #1517388: sqlite3.dll is now installed on Windows independent
317 of Tcl/Tk.
318
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000319- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old

Anthony Baxter51bcb682006-04-05 14:51:42 +0000342
343Core and builtins
344-----------------
345
Georg Brandla56b9152006-06-19 06:35:54 +0000346- Patch #1507676: Error messages returned by invalid abstract object operations
347 (such as iterating over an integer) have been improved and now include the
348 type of the offending object to help with debugging.
349
Brett Cannonea3912b2006-06-13 21:46:41 +0000350- Bug #992017: A classic class that defined a __coerce__() method that returned
351 its arguments swapped would infinitely recurse and segfault the interpreter.
352
Neal Norwitz909eb122006-06-12 02:13:21 +0000353- Fix the socket tests so they can be run concurrently.
354
Neal Norwitzb9845e72006-06-12 02:11:18 +0000355- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000356 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000357
Brett Cannon22565aa2006-06-09 22:31:23 +0000358- Bug #532646: object.__call__() will continue looking for the __call__
359 attribute on objects until one without one is found. This leads to recursion
360 when you take a class and set its __call__ attribute to an instance of the
361 class. Originally fixed for classic classes, but this fix is for new-style.
362 Removes the infinite_rec_3 crasher.
363
Georg Brandl24250812006-06-09 18:45:48 +0000364- The string and unicode methods startswith() and endswith() now accept
365 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
366
Brett Cannonde3b0522006-06-08 17:00:45 +0000367- Buffer objects, at the C level, never used the char buffer
368 implementation even when the char buffer for the wrapped object was
369 explicitly requested (originally returned the read or write buffer).
370 Now a TypeError is raised if the char buffer is not present but is
371 requested.
372
Georg Brandlddbaa662006-06-04 21:56:52 +0000373- Patch #1346214: Statements like "if 0: suite" are now again optimized
374 away like they were in Python 2.4.
375
Georg Brandlb7c8f542006-05-27 12:30:25 +0000376- Builtin exceptions are now full-blown new-style classes instead of
377 instances pretending to be classes, which speeds up exception handling
378 by about 80% in comparison to 2.5a2.
379
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000380- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
381 Unicode 4.1.
382
Georg Brandlf4ef1162006-05-26 18:03:31 +0000383- Patch #921466: sys.path_importer_cache is now used to cache valid and
384 invalid file paths for the built-in import machinery which leads to
385 fewer open calls on startup.
386
Tim Peters696cf432006-05-24 21:10:40 +0000387- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
388 of-2 bases. The largest speedup is for inputs with about 1000 decimal
389 digits. Conversion from non-power-of-2 bases remains quadratic-time in
390 the number of input digits (it was and remains linear-time for bases
391 2, 4, 8, 16 and 32).
392
Tim Petersb713ec22006-05-23 18:45:30 +0000393- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
394 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
395 an integer close to ``sys.maxint``. This was repaired by patch
396 #1335972, which also gives a nice speedup.
397
Richard Jonescebbefc2006-05-23 18:28:17 +0000398- Patch #1337051: reduced size of frame objects.
399
400- PyErr_NewException now accepts a tuple of base classes as its
401 "base" parameter.
402
Richard Jones7c88dcc2006-05-23 10:37:38 +0000403- Patch #876206: function call speedup by retaining allocated frame
404 objects.
405
Georg Brandl7b90e162006-05-18 07:01:27 +0000406- Bug #1462152: file() now checks more thoroughly for invalid mode
407 strings and removes a possible "U" before passing the mode to the
408 C library function.
409
Neal Norwitz1004a532006-05-15 07:17:23 +0000410- Patch #1488312, Fix memory alignment problem on SPARC in unicode
411
Neal Norwitz373f0a72006-05-15 07:04:36 +0000412- Bug #1487966: Fix SystemError with conditional expression in assignment
413
Martin v. Löwis879768d2006-05-11 13:28:43 +0000414- WindowsError now has two error code attributes: errno, which carries
415 the error values from errno.h, and winerror, which carries the error
416 values from winerror.h. Previous versions put the winerror.h values
417 (from GetLastError()) into the errno attribute.
418
Martin v. Löwis77736712006-05-04 05:51:03 +0000419- Patch #1475845: Raise IndentationError for unexpected indent.
420
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000421- Patch #1479181: split open() and file() from being aliases for each other.
422
Tim Peters44bd9862006-06-01 13:49:23 +0000423- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
424 methods were always silently ignored by dictionaries when comparing keys.
425 They are now passed through (except when using the C API function
426 ``PyDict_GetItem()``, whose semantics did not change).
427
428- Bug #1456209: In some obscure cases it was possible for a class with a
429 custom ``__eq__()`` method to confuse dict internals when class instances
430 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
431 No, you don't have any code that did this ;-)

437
438- Patch #1462338: Upgrade pyexpat to expat 2.0.0
439
Brett Cannon6ee7d012006-06-08 16:23:04 +0000440- Change binascii.hexlify to accept a read-only buffer instead of only a char
441 buffer and actually follow its documentation.
442
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000443- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
444
Nick Coghlanc649ec52006-05-29 12:43:05 +0000445- Patch #1478788 (modified version): The functional extension module has
446 been renamed to _functools and a functools Python wrapper module added.
447 This provides a home for additional function related utilities that are
448 not specifically about functional programming. See PEP 309.
449
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000450- Patch #1493701: performance enhancements for struct module.
451
Georg Brandl378d5922006-05-17 14:26:50 +0000452- Patch #1490224: time.altzone is now set correctly on Cygwin.
453
Georg Brandl8d3342b2006-05-16 07:38:27 +0000454- Patch #1435422: zlib's compress and decompress objects now have a
455 copy() method.
456
Andrew MacIntyre92913322006-06-13 15:04:24 +0000457- Patch #1454481: thread stack size is now tunable at runtime for thread
458 enabled builds on Windows and systems with Posix threads support.
459
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000460- On Win32, os.listdir now supports arbitrarily-long Unicode path names
461 (up to the system limit of 32K characters).
462
463- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
464 As a result, these functions now raise WindowsError instead of OSError.
465
Tim Peters7a822da2006-05-25 21:50:17 +0000466- ``time.clock()`` on Win64 should use the high-performance Windows
467 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
468 Windows platforms).
469
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000470- Calling Tk_Init twice is refused if the first call failed as that
471 may deadlock.
472
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000473- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
474 accept it without potentially using an uninitialized pointer.
475
476- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
477 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
478 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000479
Gregory P. Smith372b5832006-06-05 18:48:21 +0000480- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000481 [pybsddb project SF patch number 1466734]
482
Gregory P. Smith372b5832006-06-05 18:48:21 +0000483- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
484 parameter is supplied. [SF pybsddb bug #1477863]
485
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000486- bsddb: the __len__ method of a DB object has been fixed to return correct
487 results. It could previously incorrectly return 0 in some cases.
488 Fixes SF bug 1493322 (pybsddb bug 1184012).
489
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000490- bsddb: the bsddb.dbtables Modify method now raises the proper error and
491 aborts the db transaction safely when a modifier callback fails.
492 Fixes SF python patch/bug #1408584.
493
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000494- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000495 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000496 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
497 database calls that would previously deadlock. [SF python bug #775414]
498
Vinay Sajip28e57612006-07-01 10:45:20 +0000499- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000507- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
508 functions.
509
Martin v. Löwis3798da02006-06-17 18:44:27 +0000510- Patch #812986: Update turtle output even if not tracing.
511
Vinay Sajip28e57612006-07-01 10:45:20 +0000512- Patch #1494750: Destroy master after deleting children in

514
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000515- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
516
Martin v. Löwis337487e2006-06-17 09:15:14 +0000517- Patch #763580: Add name and value arguments to Tkinter variable
518 classes.
519
Georg Brandl83cc0d02006-06-14 08:50:03 +0000520- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
521 mime.types file for determining MIME types.
522
Georg Brandl2605ca82006-06-14 06:08:31 +0000523- Bug #1339007: Shelf objects now don't raise an exception in their
524 __del__ method when initialization failed.
525
Martin v. Löwisd8251432006-06-14 05:21:04 +0000526- Patch #1455898: The MBCS codec now supports the incremental mode for
527 double-byte encodings.
528
Tim Peters43898b42006-06-14 04:09:25 +0000529- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
530 guarantee that adjacent triples in the return list always describe
531 non-adjacent blocks. Previously, a pair of matching blocks could end
532 up being described by multiple adjacent triples that formed a partition
533 of the matching pair.
534
Greg Ward0e0c9f42006-06-11 16:24:11 +0000535- Bug #1498146: fix optparse to handle Unicode strings in option help,
536 description, and epilog.
537
Greg Wardd1c797e2006-06-11 14:42:41 +0000538- Bug #1366250: minor optparse documentation error.
539
Greg Ward7f547402006-06-11 00:40:49 +0000540- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
541 clarify docs.
542
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000543- The wsgiref package has been added to the standard library.
544
Nick Coghlan676725d2006-06-08 13:54:49 +0000545- The functions update_wrapper() and wraps() have been added to the functools
546 module. These make it easier to copy relevant metadata from the original
547 function when writing wrapper functions.
548
Tim Petersd6a9eef2006-06-05 01:48:21 +0000549- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
550 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000551
Martin v. Löwis3f767792006-06-04 19:36:28 +0000552- Patch #1359618: Speed up charmap encoder by using a trie structure
553 for lookup.
554
Tim Petersd609b1a2006-06-02 23:22:51 +0000555- The functions in the ``pprint`` module now sort dictionaries by key
556 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
557 if and only if its display required more than one line, although that
558 wasn't documented. The new behavior increases predictability; e.g.,
559 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
560
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000561- Patch #1497027: try HTTP digest auth before basic auth in urllib2
562 (thanks for J. J. Lee).
563
Georg Brandl2b330372006-05-28 20:23:12 +0000564- Patch #1496206: improve urllib2 handling of passwords with respect to
565 default HTTP and HTTPS ports.
566
George Yoshidaf3c65de2006-05-28 16:39:09 +0000567- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
568
Bob Ippolito7298f272006-05-23 18:43:47 +0000569- Patch #1281707: speed up gzip.readline.
570
Georg Brandlb89316f2006-05-17 15:51:16 +0000571- Patch #1180296: Two new functions were added to the locale module:
572 format_string() to get the effect of "format % items" but locale-aware,
573 and currency() to format a monetary number with currency sign.
574
Georg Brandle3a25832006-05-17 14:56:04 +0000575- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
576 and several features added, such as speed and geometry control.
577
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000578- Patch #1488881: add support for external file objects in bz2 compressed
579 tarfiles.
580
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000581- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
582 stdout arguments, making it possible to redirect input and output
583 for remote debugging.
584
585- Patch #1484695: Update the tarfile module to version 0.8. This fixes
586 a couple of issues, notably handling of long file names using the
587 GNU LONGNAME extension.
588
589- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
590 new flag when ``name`` is already the name of an option flag.
591
592- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
593 package.
594
595- Patch #1472854: make the rlcompleter.Completer class usable on non-
596 UNIX platforms.
597
598- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
599
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000600- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000631What's New in Python 2.5 alpha 2?
632=================================
633
634*Release date: 27-APR-2006*
635
636Core and builtins
637-----------------
638
Thomas Heller1b046642006-04-18 18:51:06 +0000639- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
640 by converting these apis from macros into exported functions again:
641
642 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
643 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
644 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
645 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
646 PyRun_String Py_CompileString
647
Martin v. Löwis45294a92006-04-18 06:24:08 +0000648- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
649
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000650- All uses of PyStructSequence_InitType have been changed to initialize
651 the type objects only once, even if the interpreter is initialized
652 multiple times.
653
Neal Norwitz61546162006-04-14 05:20:28 +0000654- Bug #1454485, array.array('u') could crash the interpreter. This was
655 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
656 to unicode when it didn't make sense. 'u#' now requires a unicode string.
657
658- Py_UNICODE is unsigned. It was always documented as unsigned, but
659 due to a bug had a signed value in previous versions.
660
Tim Peters3a5e8b12006-04-11 01:44:07 +0000661- Patch #837242: ``id()`` of any Python object always gives a positive
662 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
663 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000664 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000665 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000666
Tim Peters3a5e8b12006-04-11 01:44:07 +0000667 def __hash__(self):
668 return id(self) # WRONG
669
670 because a hash result must be a (short) Python int but it was always
671 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000672 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000673 was always usable as a hash value before this patch. That's no longer
674 necessarily so.
675
676- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000677 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000678 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000679 #1454844)
680
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000681- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
682 involving generators that have paused outside of any ``try`` or ``with``
683 blocks. (In 2.5a1, a paused generator that was part of a reference
684 cycle could not be garbage collected, regardless of whether it was
685 paused in a ``try`` or ``with`` block.)

689
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000690- Patch #1191065: Fix preprocessor problems on systems where recvfrom
691 is a macro.
692
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000693- Bug #1467952: os.listdir() now correctly raises an error if readdir()
694 fails with an error condition.
695
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000696- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
697
698- Bug #1117761: bsddb.*open() no longer raises an exception when using
699 the cachesize parameter.
700
701- Bug #1149413: bsddb.*open() no longer raises an exception when using
702 a temporary db (file=None) with the 'n' flag to truncate on open.
703
704- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
705 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000706
Armin Rigoa9017c32006-04-19 11:50:27 +0000707- Patch #1062014: AF_UNIX sockets under Linux have a special
708 abstract namespace that is now fully supported.
709
Anthony Baxter51bcb682006-04-05 14:51:42 +0000710Library
711-------
712
Peter Astrand7d1d4362006-07-14 14:04:45 +0000713- Bug #1223937: subprocess.CalledProcessError reports the exit status
714 of the process using the returncode attribute, instead of
715 abusing errno.
716
Tim Peters711bf302006-04-25 03:31:36 +0000717- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
718 a doctest to be skipped (the code is not run, and the expected output
719 or exception is ignored).
720
Nick Coghlanda2268f2006-04-24 04:37:15 +0000721- Fixed contextlib.nested to cope with exceptions being raised and
722 caught inside exit handlers.
723
Greg Wardab05edc2006-04-23 03:47:58 +0000724- Updated optparse module to Optik 1.5.1 (allow numeric constants in
725 hex, octal, or binary; add ``append_const`` action; keep going if
726 gettext cannot be imported; added ``OptionParser.destroy()`` method;
727 added ``epilog`` for better help generation).
728
Tim Peters21fbd572006-04-21 21:18:10 +0000729- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
730 called from a thread spawned as a side effect of importing a module.
731
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000732- The pydoc module now supports documenting packages contained in
733 .zip or .egg files.
734
735- The pkgutil module now has several new utility functions, such
736 as ``walk_packages()`` to support working with packages that are either
737 in the filesystem or zip files.
738
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000739- The mailbox module can now modify and delete messages from
740 mailboxes, in addition to simply reading them. Thanks to Gregory
741 K. Johnson for writing the code, and to the 2005 Google Summer of
742 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000743
Tim Petersc7605f22006-04-17 21:12:33 +0000744- The ``__del__`` method of class ``local`` in module ``_threading_local``
745 returned before accomplishing any of its intended cleanup.
746
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000747- Patch #790710: Add breakpoint command lists in pdb.
748
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000749- Patch #1063914: Add Tkinter.Misc.clipboard_get().
750
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000751- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
752
Anthony Baxtere29002c2006-04-12 12:07:31 +0000753- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
754 Windows. Bug #1469163.
755
Phillip J. Eby47032112006-04-11 01:07:43 +0000756- The warnings, linecache, inspect, traceback, site, and doctest modules
757 were updated to work correctly with modules imported from zipfiles or
758 via other PEP 302 __loader__ objects.
759
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000760- Patch #1467770: Reduce usage of subprocess._active to processes which
761 the application hasn't waited on.
762
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000763- Patch #1462222: Fix Tix.Grid.
764
Neal Norwitza31bf182006-04-09 03:35:43 +0000765- Fix exception when doing glob.glob('anything*/')
766
Skip Montanaro262fb922006-04-21 02:31:07 +0000767- The pstats.Stats class accepts an optional stream keyword argument to
768 direct output to an alternate file-like object.
769
Anthony Baxter51bcb682006-04-05 14:51:42 +0000770Build
771-----
772
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000773- The Makefile now has a reindent target, which runs reindent.py on
774 the library.
775
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000776- Patch #1470875: Building Python with MS Free Compiler
777
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000778- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000779
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000780- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
781 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000782 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000783 CXX from --with-cxx-main, see description in README.
784
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000785- Patch #1429775: Link extension modules with the shared libpython.
786
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000787- Fixed a libffi build problem on MIPS systems.
788
Tim Peters8931ff12006-05-13 23:28:20 +0000789- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
790 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
791 and "%zu" for unsigned integers of type ``size_t``.
792
Anthony Baxter51bcb682006-04-05 14:51:42 +0000793Tests
794-----
795
Nick Coghlanda2268f2006-04-24 04:37:15 +0000796- test_contextlib now checks contextlib.nested can cope with exceptions
797 being raised and caught inside exit handlers.
798
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000799- test_cmd_line now checks operation of the -m and -c command switches
800
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000801- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
802 it separately and by hand. It also wasn't cleaning up its changes to
803 the current Decimal context.
804
Thomas Woutersabd08882006-04-26 15:53:30 +0000805- regrtest.py now has a -M option to run tests that test the new limits of
806 containers, on 64-bit architectures. Running these tests is only sensible
807 on 64-bit machines with more than two gigabytes of memory. The argument
808 passed is the maximum amount of memory for the tests to use.

812
813- Added the Python benchmark suite pybench to the Tools/ directory;
814 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000816Documentation
817-------------
818
Tim Petersb06d28c2006-05-12 01:57:59 +0000819- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
820
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000821- PEP 343: Added Context Types section to the library reference
822 and attempted to bring other PEP 343 related documentation into
823 line with the implementation and/or python-dev discussions.
824
Tim Peters8dc73d22006-04-24 02:03:16 +0000825- Bug #1337990: clarified that ``doctest`` does not support examples
826 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000829What's New in Python 2.5 alpha 1?
830=================================
831
Anthony Baxterebed3f62006-04-03 15:03:44 +0000832*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000833
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000834Core and builtins
835-----------------
836
Nick Coghlan43832302006-04-23 17:04:07 +0000837- PEP 338: -m command line switch now delegates to runpy.run_module
838 allowing it to support modules in packages and zipfiles
839
Martin v. Löwisc661b882006-04-20 04:54:23 +0000840- On Windows, .DLL is not an accepted file name extension for
841 extension modules anymore; extensions are only found if they
842 end in .PYD.
843
Martin v. Löwisea62d252006-04-03 10:56:49 +0000844- Bug #1421664: sys.stderr.encoding is now set to the same value as
845 sys.stdout.encoding.
846
Neal Norwitz92e212f2006-04-03 04:48:37 +0000847- __import__ accepts keyword arguments.
848
Georg Brandlccadf842006-03-31 18:54:53 +0000849- Patch #1460496: round() now accepts keyword arguments.
850
Anthony Baxter262c00a2006-03-30 10:53:17 +0000851- Fixed bug #1459029 - unicode reprs were double-escaped.
852
Hye-Shik Changd478f342006-03-23 12:32:36 +0000853- Patch #1396919: The system scope threads are reenabled on FreeBSD
854 5.4 and later versions.
855
Neal Norwitze98ccf62006-03-23 05:39:47 +0000856- Bug #1115379: Compiling a Unicode string with an encoding declaration
857 now gives a SyntaxError.
858
Georg Brandlabd1ff82006-03-18 07:59:59 +0000859- Previously, Python code had no easy way to access the contents of a
860 cell object. Now, a ``cell_contents`` attribute has been added
861 (closes patch #1170323).
862
Tim Peterscf79aac2006-03-16 01:14:46 +0000863- Patch #1123430: Python's small-object allocator now returns an arena to
864 the system ``free()`` when all memory within an arena becomes unused
865 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
866 freed. Some applications will see a drop in virtual memory size now,
867 especially long-running applications that, from time to time, temporarily
868 use a large number of small objects. Note that when Python returns an
869 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000870 platform C library will in turn return that memory to the operating system.
871 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000872 appears to be effective at least on Microsoft C and gcc-based systems.
873 Thanks to Evan Jones for hard work and patience.
874
Georg Brandl533ff6f2006-03-08 18:09:27 +0000875- Patch #1434038: property() now uses the getter's docstring if there is
876 no "doc" argument given. This makes it possible to legitimately use
877 property() as a decorator to produce a read-only property.
878
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000879- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
880 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
881 of requiring an int or long in slicing and a few other contexts, enabling
882 other objects (e.g. Numeric Python's integers) to be used as slice indices.
883
Neal Norwitz995acdf2006-03-07 05:01:00 +0000884- Fixed various bugs reported by Coverity's Prevent tool.
885
Brett Cannonbf364092006-03-01 04:25:17 +0000886- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
887 new exception base class, BaseException, which has a new message attribute.
888 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
889 Raising a string exception now raises a DeprecationWarning.
890
Thomas Woutersfb609f42006-02-28 16:37:25 +0000891- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
892 explicitly relative, using 'from .module import name' to mean 'from the same
893 package as this module is in. Imports without dots still default to the
894 old relative-then-absolute, unless 'from __future__ import
895 absolute_import' is used.
896
Brett Cannona7446e32006-02-27 23:39:10 +0000897- Properly check if 'warnings' raises an exception (usually when a filter set
898 to "error" is triggered) when raising a warning for raising string
899 exceptions.
900
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000901- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000902 The name was removed from Include/code.h.
903
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000904- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000905
Guido van Rossum1968ad32006-02-25 22:38:04 +0000906- Patch 1433928:
907 - The copy module now "copies" function objects (as atomic objects).
908 - dict.__getitem__ now looks for a __missing__ hook before raising
909 KeyError.
910
Tim Peters84ef21c2006-02-28 20:39:06 +0000911- PEP 343: with statement implemented. Needs ``from __future__ import
912 with_statement``. Use of 'with' as a variable will generate a warning.
913 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000914 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000915 The following objects have __context__ methods:
916 - The built-in file type.
917 - The thread.LockType type.
918 - The following types defined by the threading module:
919 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
920 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000921
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000922- Fix the encodings package codec search function to only search
923 inside its own package. Fixes problem reported in patch #1433198.
924
925 Note: Codec packages should implement and register their own
926 codec search function. PEP 100 has the details.
927
Tim Peters9ea89d22006-06-04 03:26:02 +0000928- PEP 353: Using ``Py_ssize_t`` as the index type.
929
930- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
931 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
932 now allow Python to make use of memory blocks exceeding 2**32 bytes for
933 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
934 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000935
Neal Norwitzfc76d632006-01-10 06:03:13 +0000936- Patch #1400181, fix unicode string formatting to not use the locale.
937 This is how string objects work. u'%f' could use , instead of .
938 for the decimal point. Now both strings and unicode always use periods.
939
Neal Norwitz671b9e32006-01-09 07:07:12 +0000940- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
941 configure would break checking curses.h.
942
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000943- Bug #959576: The pwd module is now builtin. This allows Python to be
944 built on UNIX platforms without $HOME set.
945
Neal Norwitzc10978f2005-12-19 06:07:16 +0000946- Bug #1072182, fix some potential problems if characters are signed.
947
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000948- Bug #889500, fix line number on SyntaxWarning for global declarations.
949
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000950- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
951
Neal Norwitze7214a12005-12-18 05:03:17 +0000952- Support for converting hex strings to floats no longer works.
953 This was not portable. float('0x3') now raises a ValueError.
954
Barry Warsaw2a38a862005-12-18 01:27:35 +0000955- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000956 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000957 is now displayed in interactive prompt banner.
958
Georg Brandlfa166682005-12-17 21:45:17 +0000959- Implementation of PEP 341 - Unification of try/except and try/finally.
960 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000961 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000962
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000963- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
964 now encodes backslash correctly.
965
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000966- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
967
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000968- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000969 and long longs.
970
Neal Norwitz67715f02005-11-09 06:59:35 +0000971- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000972 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000973 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000974
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000975- Replaced most Unicode charmap codecs with new ones using the
976 new Unicode translate string feature in the builtin charmap
977 codec; the codecs were created from the mapping tables available
978 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
979 encodings now include a mapping for the Apple logo)
980
Tim Peterse3547fd2005-12-16 23:13:57 +0000981- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000982
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000983- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000984
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000985- A new AST parser implementation was completed. The abstract
986 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000987 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000988
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000989- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000990 The following code now raises a SyntaxError: foo(a = i for i in range(10))
991
Neal Norwitz708e51a2005-10-03 04:48:15 +0000992- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
993
Neal Norwitz11bd1192005-10-03 00:54:56 +0000994- SF Bug #887946: fix segfault when redirecting stdin from a directory.
995 Provide a warning when a directory is passed on the command line.
996
Neal Norwitz40d37812005-10-02 01:48:49 +0000997- Fix segfault with invalid coding.
998
999- SF bug #772896: unknown encoding results in MemoryError.
1000
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001001- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001002 supported a __len__() method which evaluated to False when the iterator
1003 was empty.
1004
Guido van Rossum630db602005-09-20 18:49:54 +00001005- On 64-bit platforms, when __len__() returns a value that cannot be
1006 represented as a C int, raise OverflowError.
1007
Skip Montanarof8948ca2005-09-19 03:54:46 +00001008- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001009 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001010
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001011- SF bug #893549: parsing keyword arguments was broken with a few format
1012 codes.
1013
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001014- Changes donated by Elemental Security to make it work on AIX 5.3
1015 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1016 bug #105470: test_pwd fails on 64bit system (Opteron).
1017
Guido van Rossum539c6622005-09-14 17:49:54 +00001018- Changes donated by Elemental Security to make it work on HP-UX 11 on
1019 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1020
Georg Brandl4550b8d2005-08-26 06:43:52 +00001021- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001022 (fixes bug #1119418).
1023
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001024- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1025
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001026- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1027 exceptions that cause a function to exit.
1028
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001029- The implementation of set() and frozenset() was revised to use its
1030 own internal data structure. Memory consumption is reduced by 1/3
1031 and there are modest speed-ups as well. The API is unchanged.
1032
Tim Petersde7990b2005-07-17 23:45:23 +00001033- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1034
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001035- SF bug #1229429: PyObject_CallMethod failed to decrement some
1036 reference counts in some error exit cases.
1037
Tim Petersecc6e6a2005-07-10 22:30:55 +00001038- SF bug #1185883: Python's small-object memory allocator took over
1039 a block managed by the platform C library whenever a realloc specified
1040 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001041 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001042 portable way to copy data from the C-managed block into Python's
1043 small-object space without risking a memory fault. Python's small-object
1044 realloc now leaves such blocks under the control of the platform C
1045 realloc.
1046
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001047- SF bug #1232517: An overflow error was not detected properly when
1048 attempting to convert a large float to an int in os.utime().
1049
Raymond Hettinger3296e692005-06-29 23:29:56 +00001050- SF bug #1224347: hex longs now print with lowercase letters just
1051 like their int counterparts.
1052
Michael W. Hudson188d4362005-06-20 16:52:57 +00001053- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1054 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1055 interpreter states; back out that fix and do a better job (see
1056 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1057 for a longer write-up of the problem).
1058
Michael W. Hudsondf888462005-06-03 14:41:55 +00001059- SF patch #1180995: marshal now uses a binary format by default when
1060 serializing floats.
1061
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001062- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1063 the routines that promise to produce IEEE 754 binary representations
1064 of floats now simply copy bytes around.
1065
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001066- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1067 278.
1068
Brett Cannonc3647ac2005-04-26 03:45:26 +00001069- patch #1109424: int, long, float, complex, and unicode now check for the
1070 proper magic slot for type conversions when subclassed. Previously the
1071 magic slot was ignored during conversion. Semantics now match the way
1072 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001073 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001074 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001075 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001076
Barry Warsawc8d907c2005-04-19 23:43:40 +00001077- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1078 NULL, now raise an AttributeError when attempting to set or delete the
1079 attribute. Previously a TypeError was raised, but this was inconsistent
1080 with the equivalent pure-Python implementation.
1081
Michael W. Hudson774479c2005-04-18 08:46:17 +00001082- It is now safe to call PyGILState_Release() before
1083 PyEval_InitThreads() (note that if there is reason to believe there
1084 are multiple threads around you still must call PyEval_InitThreads()
1085 before using the Python API; this fix is for extension modules that
1086 have no way of knowing if Python is multi-threaded yet).
1087
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001088- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1089 disabled caused a crash.
1090
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001091- Bug #1165306: instancemethod_new allowed the creation of a method
1092 with im_class == im_self == NULL, which caused a crash when called.
1093
Tim Petersecc6e6a2005-07-10 22:30:55 +00001094- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001095 fixes the crash seen in bug #1165761
1096
Raymond Hettinger96229b12005-03-11 06:49:40 +00001097- Added two new builtins, any() and all().
1098
Brett Cannon409d8f22005-03-05 06:47:57 +00001099- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001100 (e.g., ``class C(): pass`` is no longer a syntax error).
1101 Patch #1176012 added support to the 'parser' module and 'compiler' package
1102 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001103
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001104- Patch #1115086: Support PY_LONGLONG in structmember.
1105
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001106- Bug #1155938: new style classes did not check that __init__() was
1107 returning None.
1108
Tim Petersecc6e6a2005-07-10 22:30:55 +00001109- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001110 ('\') with a specific error message.
1111
Martin v. Löwisff232d72005-03-03 09:24:38 +00001112- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1113
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001114- Bug #1124295: the __name__ attribute of file objects was
1115 inadvertently made inaccessible in restricted mode.
1116
Tim Petersecc6e6a2005-07-10 22:30:55 +00001117- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001118 an ferror() call.
1119
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001120- min() and max() now support key= arguments with the same meaning as in
1121 list.sort().
1122
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001123- The peephole optimizer now performs simple constant folding in expressions:
1124 (2+3) --> (5).
1125
Raymond Hettingera422c342005-01-11 03:03:27 +00001126- set and frozenset objects can now be marshalled. SF #1098985.
1127
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001128- Bug #1077106: Poor argument checking could cause memory corruption
1129 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001130
Jeremy Hyltonab630502005-02-04 18:44:06 +00001131- The parser did not complain about future statements in illegal
1132 positions. It once again reports a syntax error if a future
1133 statement occurs after anything other than a doc string.
1134
Neil Schemenauercf52c072005-08-12 17:34:58 +00001135- Change the %s format specifier for str objects so that it returns a
1136 unicode instance if the argument is not an instance of basestring and
1137 calling __str__ on the argument returns a unicode instance.
1138
Tim Petersf4e69282006-02-27 17:15:31 +00001139- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1140 current thread state when the auto-GIL-state machinery knows about
1141 it (since the thread state is being deleted, continuing to remember it
1142 can't help, but can hurt if another thread happens to get created with
1143 the same thread id).
1144
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001145Extension Modules
1146-----------------
1147
Georg Brandl43f08a82006-03-31 18:01:16 +00001148- Patch #1380952: fix SSL objects timing out on consecutive read()s
1149
Neal Norwitz05a45592006-03-20 06:30:08 +00001150- Patch #1309579: wait3 and wait4 were added to the posix module.
1151
Anthony Baxterfa869072006-03-20 05:21:58 +00001152- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1153 In addition, the existing ulaw code was updated.
1154
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001155- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001156 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001157
Neal Norwitz10be10c2006-03-16 06:50:13 +00001158- Everything under lib-old was removed. This includes the following modules:
1159 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001160 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001161 util, whatsound, whrandom, zmod
1162
1163- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1164
1165- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001166 is deprecated. The undocumented re.engine variable no longer exists.
1167
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001168- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1169 SS2 (single-shift 2) escape sequences correctly.
1170
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001171- The unicodedata module was updated to the 4.1 version of the Unicode
1172 database. The 3.2 version is still available as unicodedata.db_3_2_0
1173 for applications that require this specific version (such as IDNA).
1174
Neal Norwitzb62c4332006-03-04 18:35:47 +00001175- The timing module is no longer built by default. It was deprecated
1176 in PEP 4 in Python 2.0 or earlier.
1177
Guido van Rossum1968ad32006-02-25 22:38:04 +00001178- Patch 1433928: Added a new type, defaultdict, to the collections module.
1179 This uses the new __missing__ hook behavior added to dict (see above).
1180
Georg Brandldbd83392006-02-20 09:42:33 +00001181- Bug #854823: socketmodule now builds on Sun platforms even when
1182 INET_ADDRSTRLEN is not defined.
1183
Georg Brandlf4f44152006-02-18 22:29:33 +00001184- Patch #1393157: os.startfile() now has an optional argument to specify
1185 a "command verb" to invoke on the file.
1186
Neal Norwitz082b2df2006-02-07 07:04:46 +00001187- Bug #876637, prevent stack corruption when socket descriptor
1188 is larger than FD_SETSIZE.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001335- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1336 been renamed to have only a single underscore prefix. This was done to
1337 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001338
Nick Coghlan43832302006-04-23 17:04:07 +00001339- PEP 338: new module runpy defines a run_module function to support
1340 executing modules which provide access to source code or a code object
1341 via the PEP 302 import mechanisms.
1342
Anthony Baxter93f5b932006-04-03 08:05:07 +00001343- The email module's parsedate_tz function now sets the daylight savings

1351 in attribute values.
1352
Anthony Baxterc51ee692006-04-01 00:57:31 +00001353- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001354 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001355 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001356 module will not be built.
1357
Tim Petersc17976e2006-04-01 00:26:53 +00001358- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1359 aren't officially supported here, and trying to use them will probably
1360 raise an exception some day. But dicts have been allowed, and "mostly
1361 worked", so support for them won't go away without warning.
1362
Georg Brandl338ef7d2006-03-31 18:42:16 +00001363- Bug #1445068: getpass.getpass() can now be given an explicit stream
1364 argument to specify where to write the prompt.
1365

1381
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001382- email 4.0 package now integrated. This is largely the same as the email 3.0
1383 package that was included in Python 2.3, except that PEP 8 module names are
1384 now used (e.g. mail.message instead of email.Message). The MIME classes
1385 have been moved to a subpackage (e.g. email.mime.text instead of
1386 email.MIMEText). The old names are still supported for now. Several
1387 deprecated Message methods have been removed and lots of bugs have been
1388 fixed. More details can be found in the email package documentation.
1389
Walter Dörwald40108c92006-03-27 08:15:44 +00001390- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1391 (a subclass of tuple) that provides incremental decoders and encoders
1392 (a way to use stateful codecs without the stream API). Python functions
1393 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1394 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1395 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001397- Patch #1359365: Calling next() on a closed StringIO.String object raises
1398 a ValueError instead of a StopIteration now (like file and cString.String do).
1399 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1400 called before (like file and StringIO.StringIO do).

Georg Brandl4edd9892006-01-13 16:59:46 +00001462- Bug #1403410: The warnings module now doesn't get confused
1463 when it can't find out the module name it generates a warning for.
Georg Brandlb709c2c2006-01-20 09:07:35 +00001464

1468
Neal Norwitz338e7862005-12-23 21:27:46 +00001469- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1470 LoadError as documented, instead of IOError. For compatibility,
1471 LoadError subclasses IOError.
1472
Brett Cannon3cbd0382005-12-16 22:49:23 +00001473- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001474 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1475 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1476 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1477 Ronald L. Rivest offered this advice for Python:
1478
1479 "The consensus of researchers in this area (at least as
1480 expressed at the NIST Hash Function Workshop 10/31/05),
1481 is that SHA-256 is a good choice for the time being, but
1482 that research should continue, and other alternatives may
1483 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001484
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001485- Added a subset of Fredrik Lundh's ElementTree package. Available

1538 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001539 correct line numbers for decoding errors in source code.

1562 to W3C name (404 -> 'Not Found'). RFE #1216944.
1563
Georg Brandl9e43acf2005-07-04 17:16:07 +00001564- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1565 as this can cause problems with apps closing all file descriptors.

1578 Bug #1224621.
1579
Raymond Hettinger68c04532005-06-10 11:05:19 +00001580- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001581 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001582 the generate_tokens() function now accepts a callable argument that
1583 terminates by raising StopIteration.
1584
Georg Brandl9166e1a2005-06-04 09:20:03 +00001585- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1589
Skip Montanaro174dd222005-05-14 20:54:16 +00001590- Patch #1120353: The xmlrpclib module provides better, more transparent,

1593 class at all.
1594
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001595- distutils.commands.upload was added to support uploading distribution

1599 them to PyPI.
1600
Raymond Hettinger267b8682005-03-27 10:47:39 +00001601- decimal operator and comparison methods now return NotImplemented
1602 instead of raising a TypeError when interacting with other types. This
1603 allows other classes to implement __radd__ style methods and have them
1604 work as expected.
1605
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001606- Bug #1163325: Decimal infinities failed to hash. Attempting to
1607 hash a NaN raised an InvalidOperation instead of a TypeError.
1608
Tim Petersecc6e6a2005-07-10 22:30:55 +00001609- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1643
Guido van Rossumd0641422005-02-03 15:01:24 +00001644- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1645 disables recursive traversal through instance attributes, which can
1646 be exploited in various ways.
1647
Tim Peterse3547fd2005-12-16 23:13:57 +00001648- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001649 flags on the HTTP listening socket.
1650
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001651- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1652 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1653
Fred Drakefbdeaad2006-07-29 16:56:15 +00001654- Patches #893642, #1039083: add allow_none, encoding arguments to
1655 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001656

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001659- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1660
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001661- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1662
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001663- Enhancements to the csv module:
1664
1665 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001666 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001667 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001668 + Dialect parameter parsing has been re-implemented to improve error
1669 reporting.
1670 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1671 dictates.
1672 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001673 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001674 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001675 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1676 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001677 + reader now allows \r characters to be quoted (previously it only allowed
1678 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001679 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001680 + Dialect classes passed to the module are no longer instantiated by
1681 the module before being parsed (the former validation scheme required
1682 this, but the mechanism was unreliable).
1683 + The dialect registry now contains instances of the internal
1684 C-coded dialect type, rather than references to python objects.
1685 + the internal c-coded dialect type is now immutable.
1686 + register_dialect now accepts the same keyword dialect specifications
1687 as the reader and writer, allowing the user to register dialects
1688 without first creating a dialect class.
1689 + a configurable limit to the size of parsed fields has been added -
1690 previously, an unmatched quote character could result in the entire
1691 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001692 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001693 the parser field size limit (returning the former limit). The initial
1694 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001695 + A line_num attribute has been added to the reader object, which tracks
1696 the number of lines read from the source iterator. This is not
1697 the same as the number of records returned, as records can span
1698 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001699 + reader and writer objects were not being registered with the cyclic-GC.
1700 This has been fixed.
1701
Brett Cannone6539c42005-01-08 02:43:53 +00001702- _DummyThread objects in the threading module now delete self.__block that is
1703 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1704 lock primitives tend to be limited in number and thus should not be wasted on
1705 a _DummyThread object. Fixes bug #1089632.
1706
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001707- The imghdr module now detects Exif files.
1708
Raymond Hettinger6065d322004-12-20 23:51:53 +00001709- StringIO.truncate() now correctly adjusts the size attribute.
1710 (Bug #951915).
1711
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001712- locale.py now uses an updated locale alias table (built using
1713 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1714 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001715 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001716
Raymond Hettinger3557f422004-12-07 12:02:02 +00001717- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1718
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001719- the pickle module no longer accepts the deprecated None option in the
1720 args tuple returned by __reduce__().
1721
Brett Cannon84667c02004-12-07 03:25:18 +00001722- optparse now optionally imports gettext. This allows its use in setup.py.
1723
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001724- the pickle module no longer uses the deprecated bin parameter.
1725
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001726- the shelve module no longer uses the deprecated binary parameter.
1727
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001728- the pstats module no longer uses the deprecated ignore() method.
1729
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001730- the filecmp module no longer uses the deprecated use_statcache argument.
1731
Raymond Hettinger664347b2004-12-04 21:21:53 +00001732- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1733 extended or overridden by subclasses. Formerly, the subclassed method would
1734 be ignored by the rest of the module. (Bug #1078905).
1735
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001736- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001737 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001738
Walter Dörwald36733692004-12-22 12:50:50 +00001739- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1740 once when a size argument is given. This prevents a buffer overflow in the
1741 tokenizer with very long source lines.
1742
Barry Warsaw538561e2006-01-01 21:48:54 +00001743- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1744 immediately after creating the object, without any intervening
1745 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001746
Skip Montanaro05885812005-01-16 20:48:27 +00001747- The reconvert.quote function can now emit triple-quoted strings. The
1748 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001749
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001750- ``UserString.MutableString`` now supports negative indices in
1751 ``__setitem__`` and ``__delitem__``
1752
Greg Ward40407942005-03-05 02:53:17 +00001753- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1754 correctly.
1755
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001756- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1757 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1758 character even if the user has passed a size parameter to get a proper
1759 line ending. Remove the special handling of a "\r\n" that has been split
1760 between two lines.
1761
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001762- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1763 about illegal code points. The codec now supports PEP 293 style error
1764 handlers.
1765
Walter Dörwald78a78b02005-09-01 12:04:29 +00001766- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001767 from the input stream, so that the output is a byte string in the correct
1768 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001769
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001770- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1771 considering it exactly like a '*'.
1772
Walter Dörwald007f8df2005-10-09 19:42:27 +00001773- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1774 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001775
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001776- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1777
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001778- Patch #1413711: Certain patterns of differences were making difflib
1779 touch the recursion limit.
1780
Walter Dörwald58917a62006-03-31 15:26:22 +00001781- Bug #947906: An object oriented interface has been added to the calendar
1782 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001783 called as a script (e.g. via ``python -mcalendar``). Localized month and
1784 weekday names can be ouput (even if an exotic encoding is used) using
1785 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001786
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001787Build
1788-----
1789
Neal Norwitz602d3392006-03-31 08:21:40 +00001790- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1791 by using -mieee gcc option.
1792
Martin v. Löwis86d66262006-02-17 08:40:11 +00001793- Patch #1432345: Make python compile on DragonFly.
1794
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001795- Build support for Win64-AMD64 was added.
1796
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001797- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1798
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001799- Patch #881820: look for openpty and forkpty also in libbsd.
1800
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001801- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1802 The zlib module is now builtin on Windows.
1803
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001804- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1805
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001806- Bug #1189330: configure did not correctly determine the necessary
1807 value of LINKCC if python was built with GCC 4.0.
1808
Trent Mick8321b422005-07-26 02:29:21 +00001809- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1810 vulnerability in zlib 1.2.1 and 1.2.2.
1811
Brett Cannon08cd5982005-04-24 22:26:38 +00001812- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1813 flags that change binary compatibility. Changes were also made to
1814 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001815 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001816
Bob Ippolitoed233462005-03-29 13:47:59 +00001817- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1818 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1819 no longer exists). This configure patch makes things right.
1820
Martin v. Löwise2713be2005-03-08 15:03:08 +00001821- Bug #1158607: Build with --disable-unicode again.
1822
Brett Cannon46d96232005-02-16 00:07:19 +00001823- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1824 defined. Discovered as a result of not being able to build on OS X.
1825
Brett Cannon516592f2004-12-07 00:42:59 +00001826- setup.py now uses the directories specified in LDFLAGS using the -L option
1827 and in CPPFLAGS using the -I option for adding library and include
1828 directories, respectively, for compiling extension modules against. This has
1829 led to the core being compiled using the values in CPPFLAGS. It also removes
1830 the need for the special-casing of both DarwinPorts and Fink for darwin since
1831 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1832 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1833 Fink, ``-I/opt/local/include`` for DarwinPorts).
1834
Brett Cannon43802422005-02-10 20:48:03 +00001835- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1836 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1837 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1838 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001840C API
1841-----
1842
Tim Petersc9d78aa2006-03-26 23:27:58 +00001843- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1844 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1845 is obtained via the ``PyObject_`` family, it must be released via the
1846 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1847 always been officially true, but when Python's small-object allocator was
1848 introduced, an attempt was made to cater to a few extension modules
1849 discovered at the time that obtained memory via ``PyObject_New`` but
1850 released it via ``PyMem_DEL``. It's years later, and if such code still
1851 exists it will fail now (probably with segfaults, but calling wrong
1852 low-level memory management functions can yield many symptoms).
1853
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001854- Added a C API for set and frozenset objects.
1855
Raymond Hettinger66517482004-12-03 11:45:13 +00001856- Removed PyRange_New().
1857
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001858- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1859 mapping argument now. This string is used as a mapping table. Byte values
1860 greater than the length of the string and 0xFFFE are treated as undefined
1861 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001867- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001868
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001869- Patch #1276356: New resource "urlfetch" is implemented. This enables
1870 even impatient people to run tests that require remote files.
