Fred Drake53912162006-07-29 13:22:49 +00007What's New in Python 2.5 beta 3?
8================================
Neal Norwitza1f10902006-07-12 07:28:29 +00009
10*Release date: XX-AUG-2006*
11
12Core and builtins
13-----------------
14
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000015- Bug #1515471: string.replace() accepts character buffers again.
16
Neal Norwitz07aadb12006-07-30 06:55:48 +000017- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
18 This provides the proper warning for struct.pack().
19 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
20
Neal Norwitz0d62a062006-07-30 06:53:31 +000021- Patch #1531113: Fix augmented assignment with yield expressions.
22 Also fix a SystemError when trying to assign to yield expressions.
23
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000024- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
25 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
26 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
27 excessive filesystem operations during imports.
28
Tim Petersbc24eee2006-07-27 01:14:53 +000029- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
30 operations on signed longs that are formally undefined by C.
31 Unfortunately, at least one compiler now cares about that, so complicated
32 the code to make that compiler happy again.
33
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000034- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
35
Martin v. Löwisd22968a2006-07-24 11:54:53 +000036- Patch #1232023: Stop including current directory in search
37 path on Windows.
38
Neal Norwitze1fdb322006-07-21 05:32:28 +000039- Fix some potential crashes found with failmalloc.
40
Neal Norwitze7563102006-07-17 01:00:16 +000041- Fix warnings reported by Klocwork's static analysis tool.
42
Neal Norwitz84be93b2006-07-16 01:50:38 +000043- Bug #1512814, Fix incorrect lineno's when code within a function
44 had more than 255 blank lines.
45
Georg Brandl9dceedb2006-07-12 15:31:17 +000046- Patch #1521179: Python now accepts the standard options ``--help`` and
47 ``--version`` as well as ``/?`` on Windows.
48
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000049- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000050 again. Fixing this problem required changing the .pyc magic number.
51 This means that .pyc files generated before 2.5c1 will be regenerated.
52
Tim Peters112aad32006-07-19 00:03:19 +000053- Bug #1524317: Compiling Python ``--without-threads`` failed.
54 The Python core compiles again then, and, in a build without threads, the
55 new ``sys._current_frames()`` returns a dictionary with one entry,
56 mapping the faux "thread id" 0 to the current frame.
57
Ronald Oussoren3075e162006-07-25 20:28:55 +000058- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000059
Ronald Oussoren3075e162006-07-25 20:28:55 +000060
Neal Norwitza1f10902006-07-12 07:28:29 +000061Library
62-------
63
Georg Brandle34ac7c2006-07-30 11:07:23 +000064- Bug #1002398: The documentation for os.path.sameopenfile now correctly
65 refers to file descriptors, not file objects.
66
Fred Drakefbdeaad2006-07-29 16:56:15 +000067- Rename of the xml package to xmlcore, and the import hackery done to
68 make it appear at both names, has been removed. Bug #1511497,
69 #1513611, and probably others.
70
Georg Brandledd9b0d2006-07-29 09:33:26 +000071- Bug #1441397: The compiler module now recognizes module and function
72 docstrings correctly as it did in Python 2.4.
73
Tim Peters6f681472006-07-27 23:44:37 +000074- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
75 lost that tests are sorted by name before being run. This rarely
76 matters for well-written tests, but can create baffling symptoms if
77 side effects from one test to the next affect outcomes. ``DocTestFinder``
78 has been changed to sort the list of tests it returns.
79
Martin v. Löwis997ceff2006-07-27 06:38:16 +000080- The distutils version has been changed to 2.5.0.
81
Martin v. Löwis9298eff2006-07-26 12:12:56 +000082- Bug #978833: Really close underlying socket in _socketobject.close.
83
Georg Brandl0619a322006-07-26 07:40:17 +000084- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
85 with title().
86
Georg Brandlcf0c1722006-07-26 07:23:32 +000087- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
88 to recursive calls and call it with the failing package name.
89
Martin v. Löwis0b483032006-07-25 09:53:12 +000090- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
91
Georg Brandlc13c34c2006-07-24 14:09:56 +000092- Patch #1515343: Fix printing of deprecated string exceptions with a
93 value in the traceback module.
94
Greg Ward48fae7a2006-07-23 16:05:51 +000095- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
96
Martin v. Löwis426f4a12006-07-18 17:46:31 +000097- Patch #1524429: Use repr() instead of backticks in Tkinter again.
98
Brett Cannoncaebe222006-07-18 04:41:36 +000099- Bug #1520914: Change time.strftime() to accept a zero for any position in its
100 argument tuple. For arguments where zero is illegal, the value is forced to
101 the minimum value that is correct. This is to support an undocumented but
102 common way people used to fill in inconsequential information in the time
103 tuple pre-2.4.
104
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000105- Patch #1220874: Update the binhex module for Mach-O.
106
Barry Warsawb110bad2006-07-21 14:51:07 +0000107- The email package has improved RFC 2231 support, specifically for
108 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
109 (name*0=<blah>) parameter continuations. This may change the types of
110 values returned from email.message.Message.get_param() and friends.
111 Specifically in some cases where non-encoded continuations were used,
112 get_param() used to return a 3-tuple of (None, None, string) whereas now it
113 will just return the string (since non-encoded continuations don't have
114 charset and language parts).
115
116 Also, whereas % values were decoded in all parameter continuations, they are
117 now only decoded in encoded parameter parts.
118
Ronald Oussoren3075e162006-07-25 20:28:55 +0000119- Bug #1517990: IDLE keybindings on MacOS X now work correctly
120
121- Bug #1517996: IDLE now longer shows the default Tk menu when a
122 path browser, class browser or debugger is the frontmost window on MacOS X
123
Barry Warsaw00decd72006-07-27 23:43:15 +0000124- Patch #1520294: Support for getset and member descriptors in types.py,
125 inspect.py, and pydoc.py. Specifically, this allows for querying the type
126 of an object against these built-in types and more importantly, for getting
127 their docstrings printed in the interactive interpreter's help() function.
128
Ronald Oussoren3075e162006-07-25 20:28:55 +0000129
Neal Norwitza1f10902006-07-12 07:28:29 +0000130Extension Modules
131-----------------
132
Thomas Heller1393d6a2006-07-28 21:43:20 +0000133- Patch #1529514: The _ctypes extension is now compiled on more
134 openbsd target platforms.
135
Tim Peters9cab5932006-07-28 00:30:00 +0000136- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
137 a memory leak, affecting pickles and deep copies.
138
Tim Petersbc24eee2006-07-27 01:14:53 +0000139- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000140 Paul Eggert.
141
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000142- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
143
Thomas Hellerce049a02006-07-14 17:51:14 +0000144- Patch #1521817: Index range checking on ctypes arrays containing
145 exactly one element enabled again. This allows iterating over these
146 arrays, without the need to check the array size before.
147
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000148- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000149 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000150 /dev/null in certain cases; this is now fixed.
151
Thomas Heller47d7a062006-07-12 08:43:47 +0000152- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
153 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000154
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000155- Because of a misspelled preprocessor symbol, ctypes was always
156 compiled without thread support; this is now fixed.
157
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000158- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
159 methods now allow their database parameter to be None as the
160 sleepycat API allows.
161
Matt Flemingec926502006-07-28 11:27:27 +0000162- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
163 bluetooth API compared with Linux and FreeBSD.
164
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000165Tests
166-----
167
168- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
169 how long the test file should take to play. Now accepts taking 2.93 secs
170 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
171
Georg Brandl4793aa32006-07-28 18:31:39 +0000172- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
173 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
174 run via ``regrtest.py``. Now they do.

Georg Brandlad29e632006-06-21 17:45:17 +0000181
182Core and builtins
183-----------------
184
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000185- Bug #1441486: The literal representation of -(sys.maxint - 1)
186 again evaluates to a int object, not a long.
187
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000188- Bug #1501934: The scope of global variables that are locally assigned
189 using augmented assignment is now correctly determined.
190
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000191- Bug #927248: Recursive method-wrapper objects can now safely
192 be released.
193
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000194- Bug #1417699: Reject locale-specific decimal point in float()
195 and atof().
196
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000197- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
198 omit a default "error" argument for NULL pointer. This allows
199 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000200
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000201- Bug #1519018: 'as' is now validated properly in import statements.
202
Neal Norwitz28746ab2006-07-09 22:14:42 +0000203- On 64 bit systems, int literals that use less than 64 bits are
204 now ints rather than longs.
205
Neal Norwitzed657552006-07-10 00:04:44 +0000206- Bug #1512814, Fix incorrect lineno's when code at module scope
207 started after line 256.
208
Tim Peters32a83612006-07-10 21:08:24 +0000209- New function ``sys._current_frames()`` returns a dict mapping thread
210 id to topmost thread stack frame. This is for expert use, and is
211 especially useful for debugging application deadlocks. The functionality
212 was previously available in Fazal Majid's ``threadframe`` extension
213 module, but it wasn't possible to do this in a wholly threadsafe way from
214 an extension.
215
Georg Brandlad29e632006-06-21 17:45:17 +0000216Library
217-------
218

220
Tim Peters32a83612006-07-10 21:08:24 +0000221- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000222 environment variable to be set in order to the SDK environment
223 for finding the compiler, include files, etc.
224
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000225- Bug #1515998: Properly generate logical ids for files in bdist_msi.
226

228
Thomas Woutersadd19112006-07-05 11:03:49 +0000229- string.Template() now correctly handles tuple-values. Previously,
230 multi-value tuples would raise an exception and single-value tuples would
231 be treated as the value they contain, instead.
232
Martin v. Löwisede77f52006-07-03 13:01:35 +0000233- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
234 even if some data are received.
235
Martin v. Löwis45482392006-07-03 12:28:58 +0000236- Bug #1267547: Put proper recursive setup.py call into the

240 degrees and radians.
241
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000242- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000243 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000244
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000245- Bug #1514703: Only setup canvas window in turtle when the canvas
246 is created.
247
Martin v. Löwis7596e832006-07-01 15:33:37 +0000248- Bug #1513223: .close() of a _socketobj now releases the underlying

255 sgmllib ('[' and ']' were not accepted).
256
Georg Brandl1be63af2006-06-28 20:23:25 +0000257- Fix a bug in the turtle module's end_fill function.
258
Brett Cannon53ab5b72006-06-22 16:49:14 +0000259- Bug #1510580: The 'warnings' module improperly required that a Warning
260 category be either a types.ClassType and a subclass of Warning. The proper
261 check is just that it is a subclass with Warning as the documentation states.
262
Georg Brandlad29e632006-06-21 17:45:17 +0000263- The compiler module now correctly compiles the new try-except-finally
264 statement (bug #1509132).
265
Neal Norwitz60373cd2006-06-22 06:30:50 +0000266- The wsgiref package is now installed properly on Unix.
267
Vinay Sajip28e57612006-07-01 10:45:20 +0000268- A bug was fixed in logging.config.fileConfig() which caused a crash on
269 shutdown when fileConfig() was called multiple times.
270
Gerhard Häring762fbd32006-07-02 17:48:30 +0000271- The sqlite3 module did cut off data from the SQLite database at the first
272 null character before sending it to a custom converter. This has been fixed
273 now.
274
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000275Extension Modules
276-----------------
277
Tim Peters112aad32006-07-19 00:03:19 +0000278- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
279 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
280 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000281
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000282- Assigning None to pointer type fields in ctypes structures possible
283 overwrote the wrong fields, this is fixed now.
284
285- Fixed a segfault in _ctypes when ctypes.wintypes were imported
286 on non-Windows platforms.
287
288- Bug #1518190: The ctypes.c_void_p constructor now accepts any
289 integer or long, without range checking.
290
291- Patch #1517790: It is now possible to use custom objects in the ctypes
292 foreign function argtypes sequence as long as they provide a from_param
293 method, no longer is it required that the object is a ctypes type.
294
295- The '_ctypes' extension module now works when Python is configured
296 with the --without-threads option.
297
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000298- Bug #1513646: os.access on Windows now correctly determines write
299 access, again.
300
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000301- Bug #1512695: cPickle.loads could crash if it was interrupted with
302 a KeyboardInterrupt.
303
Neal Norwitza12aa882006-07-06 06:45:08 +0000304- Bug #1296433: parsing XML with a non-default encoding and
305 a CharacterDataHandler could crash the interpreter in pyexpat.

308
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000309Build
310-----
311
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000312- Automate Windows build process for the Win64 SSL module.
313
Tim Peters32a83612006-07-10 21:08:24 +0000314- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000315 Previously, the slight difference could cause compilation errors of the
316 'zlib' module on systems with more than one version of zlib.
317
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000318- The MSI compileall step was fixed to also support a TARGETDIR
319 with spaces in it.
320
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000321- Bug #1517388: sqlite3.dll is now installed on Windows independent
322 of Tcl/Tk.
323
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000324- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000325 trying to be installed even though it's empty.

337 documentation for the warnings module.
338
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000339- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000345
Anthony Baxterd1136802006-06-19 12:04:15 +0000346*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000347
348Core and builtins
349-----------------
350
Georg Brandla56b9152006-06-19 06:35:54 +0000351- Patch #1507676: Error messages returned by invalid abstract object operations
352 (such as iterating over an integer) have been improved and now include the
353 type of the offending object to help with debugging.
354
Brett Cannonea3912b2006-06-13 21:46:41 +0000355- Bug #992017: A classic class that defined a __coerce__() method that returned
356 its arguments swapped would infinitely recurse and segfault the interpreter.
357
Neal Norwitz909eb122006-06-12 02:13:21 +0000358- Fix the socket tests so they can be run concurrently.
359
Neal Norwitzb9845e72006-06-12 02:11:18 +0000360- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000361 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000362
Brett Cannon22565aa2006-06-09 22:31:23 +0000363- Bug #532646: object.__call__() will continue looking for the __call__
364 attribute on objects until one without one is found. This leads to recursion
365 when you take a class and set its __call__ attribute to an instance of the
366 class. Originally fixed for classic classes, but this fix is for new-style.
367 Removes the infinite_rec_3 crasher.
368
Georg Brandl24250812006-06-09 18:45:48 +0000369- The string and unicode methods startswith() and endswith() now accept
370 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
371
Brett Cannonde3b0522006-06-08 17:00:45 +0000372- Buffer objects, at the C level, never used the char buffer
373 implementation even when the char buffer for the wrapped object was
374 explicitly requested (originally returned the read or write buffer).
375 Now a TypeError is raised if the char buffer is not present but is
376 requested.
377
Georg Brandlddbaa662006-06-04 21:56:52 +0000378- Patch #1346214: Statements like "if 0: suite" are now again optimized
379 away like they were in Python 2.4.
380
Georg Brandlb7c8f542006-05-27 12:30:25 +0000381- Builtin exceptions are now full-blown new-style classes instead of
382 instances pretending to be classes, which speeds up exception handling
383 by about 80% in comparison to 2.5a2.
384
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000385- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
386 Unicode 4.1.
387
Georg Brandlf4ef1162006-05-26 18:03:31 +0000388- Patch #921466: sys.path_importer_cache is now used to cache valid and
389 invalid file paths for the built-in import machinery which leads to
390 fewer open calls on startup.
391
Tim Peters696cf432006-05-24 21:10:40 +0000392- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
393 of-2 bases. The largest speedup is for inputs with about 1000 decimal
394 digits. Conversion from non-power-of-2 bases remains quadratic-time in
395 the number of input digits (it was and remains linear-time for bases
396 2, 4, 8, 16 and 32).
397
Tim Petersb713ec22006-05-23 18:45:30 +0000398- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
399 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
400 an integer close to ``sys.maxint``. This was repaired by patch
401 #1335972, which also gives a nice speedup.
402
Richard Jonescebbefc2006-05-23 18:28:17 +0000403- Patch #1337051: reduced size of frame objects.
404
405- PyErr_NewException now accepts a tuple of base classes as its
406 "base" parameter.
407
Richard Jones7c88dcc2006-05-23 10:37:38 +0000408- Patch #876206: function call speedup by retaining allocated frame
409 objects.
410
Georg Brandl7b90e162006-05-18 07:01:27 +0000411- Bug #1462152: file() now checks more thoroughly for invalid mode
412 strings and removes a possible "U" before passing the mode to the
413 C library function.
414
Neal Norwitz1004a532006-05-15 07:17:23 +0000415- Patch #1488312, Fix memory alignment problem on SPARC in unicode
416
Neal Norwitz373f0a72006-05-15 07:04:36 +0000417- Bug #1487966: Fix SystemError with conditional expression in assignment
418
Martin v. Löwis879768d2006-05-11 13:28:43 +0000419- WindowsError now has two error code attributes: errno, which carries
420 the error values from errno.h, and winerror, which carries the error
421 values from winerror.h. Previous versions put the winerror.h values
422 (from GetLastError()) into the errno attribute.
423
Martin v. Löwis77736712006-05-04 05:51:03 +0000424- Patch #1475845: Raise IndentationError for unexpected indent.
425
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000426- Patch #1479181: split open() and file() from being aliases for each other.
427
Tim Peters44bd9862006-06-01 13:49:23 +0000428- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
429 methods were always silently ignored by dictionaries when comparing keys.
430 They are now passed through (except when using the C API function
431 ``PyDict_GetItem()``, whose semantics did not change).
432
433- Bug #1456209: In some obscure cases it was possible for a class with a
434 custom ``__eq__()`` method to confuse dict internals when class instances
435 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
436 No, you don't have any code that did this ;-)

442
443- Patch #1462338: Upgrade pyexpat to expat 2.0.0
444
Brett Cannon6ee7d012006-06-08 16:23:04 +0000445- Change binascii.hexlify to accept a read-only buffer instead of only a char
446 buffer and actually follow its documentation.
447
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000448- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
449
Nick Coghlanc649ec52006-05-29 12:43:05 +0000450- Patch #1478788 (modified version): The functional extension module has
451 been renamed to _functools and a functools Python wrapper module added.
452 This provides a home for additional function related utilities that are
453 not specifically about functional programming. See PEP 309.
454
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000455- Patch #1493701: performance enhancements for struct module.
456
Georg Brandl378d5922006-05-17 14:26:50 +0000457- Patch #1490224: time.altzone is now set correctly on Cygwin.
458
Georg Brandl8d3342b2006-05-16 07:38:27 +0000459- Patch #1435422: zlib's compress and decompress objects now have a
460 copy() method.
461
Andrew MacIntyre92913322006-06-13 15:04:24 +0000462- Patch #1454481: thread stack size is now tunable at runtime for thread
463 enabled builds on Windows and systems with Posix threads support.
464
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000465- On Win32, os.listdir now supports arbitrarily-long Unicode path names
466 (up to the system limit of 32K characters).
467
468- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
469 As a result, these functions now raise WindowsError instead of OSError.
470
Tim Peters7a822da2006-05-25 21:50:17 +0000471- ``time.clock()`` on Win64 should use the high-performance Windows
472 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
473 Windows platforms).
474
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000475- Calling Tk_Init twice is refused if the first call failed as that
476 may deadlock.
477
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000478- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
479 accept it without potentially using an uninitialized pointer.
480
481- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
482 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
483 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000484
Gregory P. Smith372b5832006-06-05 18:48:21 +0000485- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000486 [pybsddb project SF patch number 1466734]
487
Gregory P. Smith372b5832006-06-05 18:48:21 +0000488- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
489 parameter is supplied. [SF pybsddb bug #1477863]
490
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000491- bsddb: the __len__ method of a DB object has been fixed to return correct
492 results. It could previously incorrectly return 0 in some cases.
493 Fixes SF bug 1493322 (pybsddb bug 1184012).
494
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000495- bsddb: the bsddb.dbtables Modify method now raises the proper error and
496 aborts the db transaction safely when a modifier callback fails.
497 Fixes SF python patch/bug #1408584.
498
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000499- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000500 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000501 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
502 database calls that would previously deadlock. [SF python bug #775414]
503
Vinay Sajip28e57612006-07-01 10:45:20 +0000504- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000505

511
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000512- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
513 functions.
514
Martin v. Löwis3798da02006-06-17 18:44:27 +0000515- Patch #812986: Update turtle output even if not tracing.
516
Vinay Sajip28e57612006-07-01 10:45:20 +0000517- Patch #1494750: Destroy master after deleting children in

519
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000520- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
521
Martin v. Löwis337487e2006-06-17 09:15:14 +0000522- Patch #763580: Add name and value arguments to Tkinter variable
523 classes.
524
Georg Brandl83cc0d02006-06-14 08:50:03 +0000525- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
526 mime.types file for determining MIME types.
527
Georg Brandl2605ca82006-06-14 06:08:31 +0000528- Bug #1339007: Shelf objects now don't raise an exception in their
529 __del__ method when initialization failed.
530
Martin v. Löwisd8251432006-06-14 05:21:04 +0000531- Patch #1455898: The MBCS codec now supports the incremental mode for
532 double-byte encodings.
533
Tim Peters43898b42006-06-14 04:09:25 +0000534- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
535 guarantee that adjacent triples in the return list always describe
536 non-adjacent blocks. Previously, a pair of matching blocks could end
537 up being described by multiple adjacent triples that formed a partition
538 of the matching pair.
539
Greg Ward0e0c9f42006-06-11 16:24:11 +0000540- Bug #1498146: fix optparse to handle Unicode strings in option help,
541 description, and epilog.
542
Greg Wardd1c797e2006-06-11 14:42:41 +0000543- Bug #1366250: minor optparse documentation error.
544
Greg Ward7f547402006-06-11 00:40:49 +0000545- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
546 clarify docs.
547
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000548- The wsgiref package has been added to the standard library.
549
Nick Coghlan676725d2006-06-08 13:54:49 +0000550- The functions update_wrapper() and wraps() have been added to the functools
551 module. These make it easier to copy relevant metadata from the original
552 function when writing wrapper functions.
553
Tim Petersd6a9eef2006-06-05 01:48:21 +0000554- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
555 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000556
Martin v. Löwis3f767792006-06-04 19:36:28 +0000557- Patch #1359618: Speed up charmap encoder by using a trie structure
558 for lookup.
559
Tim Petersd609b1a2006-06-02 23:22:51 +0000560- The functions in the ``pprint`` module now sort dictionaries by key
561 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
562 if and only if its display required more than one line, although that
563 wasn't documented. The new behavior increases predictability; e.g.,
564 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
565
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000566- Patch #1497027: try HTTP digest auth before basic auth in urllib2
567 (thanks for J. J. Lee).
568
Georg Brandl2b330372006-05-28 20:23:12 +0000569- Patch #1496206: improve urllib2 handling of passwords with respect to
570 default HTTP and HTTPS ports.
571
George Yoshidaf3c65de2006-05-28 16:39:09 +0000572- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
573
Bob Ippolito7298f272006-05-23 18:43:47 +0000574- Patch #1281707: speed up gzip.readline.
575
Georg Brandlb89316f2006-05-17 15:51:16 +0000576- Patch #1180296: Two new functions were added to the locale module:
577 format_string() to get the effect of "format % items" but locale-aware,
578 and currency() to format a monetary number with currency sign.
579
Georg Brandle3a25832006-05-17 14:56:04 +0000580- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
581 and several features added, such as speed and geometry control.
582
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000583- Patch #1488881: add support for external file objects in bz2 compressed
584 tarfiles.
585
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000586- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
587 stdout arguments, making it possible to redirect input and output
588 for remote debugging.
589
590- Patch #1484695: Update the tarfile module to version 0.8. This fixes
591 a couple of issues, notably handling of long file names using the
592 GNU LONGNAME extension.
593
594- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
595 new flag when ``name`` is already the name of an option flag.
596
597- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
598 package.
599
600- Patch #1472854: make the rlcompleter.Completer class usable on non-
601 UNIX platforms.
602
603- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
604
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000605- Bug #1472827: correctly escape newlines and tabs in attribute values in

Martin v. Löwis222c5152006-06-03 07:37:13 +0000614- OpenBSD 3.9 is supported now.
615
Martin v. Löwisa43190b2006-05-22 09:15:18 +0000616- Patch #1492356: Port to Windows CE.
617
Neal Norwitz58e28882006-05-19 07:00:58 +0000618- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000636What's New in Python 2.5 alpha 2?
637=================================
638
639*Release date: 27-APR-2006*
640
641Core and builtins
642-----------------
643
Thomas Heller1b046642006-04-18 18:51:06 +0000644- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
645 by converting these apis from macros into exported functions again:
646
647 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
648 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
649 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
650 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
651 PyRun_String Py_CompileString
652
Martin v. Löwis45294a92006-04-18 06:24:08 +0000653- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
654
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000655- All uses of PyStructSequence_InitType have been changed to initialize
656 the type objects only once, even if the interpreter is initialized
657 multiple times.
658
Neal Norwitz61546162006-04-14 05:20:28 +0000659- Bug #1454485, array.array('u') could crash the interpreter. This was
660 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
661 to unicode when it didn't make sense. 'u#' now requires a unicode string.
662
663- Py_UNICODE is unsigned. It was always documented as unsigned, but
664 due to a bug had a signed value in previous versions.
665
Tim Peters3a5e8b12006-04-11 01:44:07 +0000666- Patch #837242: ``id()`` of any Python object always gives a positive
667 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
668 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000669 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000670 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000671
Tim Peters3a5e8b12006-04-11 01:44:07 +0000672 def __hash__(self):
673 return id(self) # WRONG
674
675 because a hash result must be a (short) Python int but it was always
676 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000677 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000678 was always usable as a hash value before this patch. That's no longer
679 necessarily so.
680
681- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000682 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000683 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000684 #1454844)
685
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000686- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
687 involving generators that have paused outside of any ``try`` or ``with``
688 blocks. (In 2.5a1, a paused generator that was part of a reference
689 cycle could not be garbage collected, regardless of whether it was
690 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000692Extension Modules
693-----------------
694
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000695- Patch #1191065: Fix preprocessor problems on systems where recvfrom
696 is a macro.
697
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000698- Bug #1467952: os.listdir() now correctly raises an error if readdir()
699 fails with an error condition.
700
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000701- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
702
703- Bug #1117761: bsddb.*open() no longer raises an exception when using
704 the cachesize parameter.
705
706- Bug #1149413: bsddb.*open() no longer raises an exception when using
707 a temporary db (file=None) with the 'n' flag to truncate on open.
708
709- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
710 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000711
Armin Rigoa9017c32006-04-19 11:50:27 +0000712- Patch #1062014: AF_UNIX sockets under Linux have a special
713 abstract namespace that is now fully supported.
714
Anthony Baxter51bcb682006-04-05 14:51:42 +0000715Library
716-------
717
Peter Astrand7d1d4362006-07-14 14:04:45 +0000718- Bug #1223937: subprocess.CalledProcessError reports the exit status
719 of the process using the returncode attribute, instead of
720 abusing errno.
721
Tim Peters711bf302006-04-25 03:31:36 +0000722- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
723 a doctest to be skipped (the code is not run, and the expected output
724 or exception is ignored).
725
Nick Coghlanda2268f2006-04-24 04:37:15 +0000726- Fixed contextlib.nested to cope with exceptions being raised and
727 caught inside exit handlers.
728
Greg Wardab05edc2006-04-23 03:47:58 +0000729- Updated optparse module to Optik 1.5.1 (allow numeric constants in
730 hex, octal, or binary; add ``append_const`` action; keep going if
731 gettext cannot be imported; added ``OptionParser.destroy()`` method;
732 added ``epilog`` for better help generation).
733
Tim Peters21fbd572006-04-21 21:18:10 +0000734- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
735 called from a thread spawned as a side effect of importing a module.
736
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000737- The pydoc module now supports documenting packages contained in
738 .zip or .egg files.
739
740- The pkgutil module now has several new utility functions, such
741 as ``walk_packages()`` to support working with packages that are either
742 in the filesystem or zip files.
743
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000744- The mailbox module can now modify and delete messages from
745 mailboxes, in addition to simply reading them. Thanks to Gregory
746 K. Johnson for writing the code, and to the 2005 Google Summer of
747 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000748
Tim Petersc7605f22006-04-17 21:12:33 +0000749- The ``__del__`` method of class ``local`` in module ``_threading_local``
750 returned before accomplishing any of its intended cleanup.
751
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000752- Patch #790710: Add breakpoint command lists in pdb.
753
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000754- Patch #1063914: Add Tkinter.Misc.clipboard_get().
755
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000756- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
757
Anthony Baxtere29002c2006-04-12 12:07:31 +0000758- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
759 Windows. Bug #1469163.
760
Phillip J. Eby47032112006-04-11 01:07:43 +0000761- The warnings, linecache, inspect, traceback, site, and doctest modules
762 were updated to work correctly with modules imported from zipfiles or
763 via other PEP 302 __loader__ objects.
764
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000765- Patch #1467770: Reduce usage of subprocess._active to processes which
766 the application hasn't waited on.
767
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000768- Patch #1462222: Fix Tix.Grid.
769
Neal Norwitza31bf182006-04-09 03:35:43 +0000770- Fix exception when doing glob.glob('anything*/')
771
Skip Montanaro262fb922006-04-21 02:31:07 +0000772- The pstats.Stats class accepts an optional stream keyword argument to
773 direct output to an alternate file-like object.
774
Anthony Baxter51bcb682006-04-05 14:51:42 +0000775Build
776-----
777
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000778- The Makefile now has a reindent target, which runs reindent.py on
779 the library.
780
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000781- Patch #1470875: Building Python with MS Free Compiler
782
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000783- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000784
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000785- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
786 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000787 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000788 CXX from --with-cxx-main, see description in README.
789
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000790- Patch #1429775: Link extension modules with the shared libpython.
791
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000792- Fixed a libffi build problem on MIPS systems.
793
Tim Peters8931ff12006-05-13 23:28:20 +0000794- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
795 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
796 and "%zu" for unsigned integers of type ``size_t``.
797
Anthony Baxter51bcb682006-04-05 14:51:42 +0000798Tests
799-----
800
Nick Coghlanda2268f2006-04-24 04:37:15 +0000801- test_contextlib now checks contextlib.nested can cope with exceptions
802 being raised and caught inside exit handlers.
803
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000804- test_cmd_line now checks operation of the -m and -c command switches
805
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000806- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
807 it separately and by hand. It also wasn't cleaning up its changes to
808 the current Decimal context.
809
Thomas Woutersabd08882006-04-26 15:53:30 +0000810- regrtest.py now has a -M option to run tests that test the new limits of
811 containers, on 64-bit architectures. Running these tests is only sensible
812 on 64-bit machines with more than two gigabytes of memory. The argument
813 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000821Documentation
822-------------
823
Tim Petersb06d28c2006-05-12 01:57:59 +0000824- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
825
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000826- PEP 343: Added Context Types section to the library reference
827 and attempted to bring other PEP 343 related documentation into
828 line with the implementation and/or python-dev discussions.
829
Tim Peters8dc73d22006-04-24 02:03:16 +0000830- Bug #1337990: clarified that ``doctest`` does not support examples
831 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000834What's New in Python 2.5 alpha 1?
835=================================
836
Anthony Baxterebed3f62006-04-03 15:03:44 +0000837*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000838
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000839Core and builtins
840-----------------
841
Nick Coghlan43832302006-04-23 17:04:07 +0000842- PEP 338: -m command line switch now delegates to runpy.run_module
843 allowing it to support modules in packages and zipfiles
844
Martin v. Löwisc661b882006-04-20 04:54:23 +0000845- On Windows, .DLL is not an accepted file name extension for
846 extension modules anymore; extensions are only found if they
847 end in .PYD.
848
Martin v. Löwisea62d252006-04-03 10:56:49 +0000849- Bug #1421664: sys.stderr.encoding is now set to the same value as
850 sys.stdout.encoding.
851
Neal Norwitz92e212f2006-04-03 04:48:37 +0000852- __import__ accepts keyword arguments.
853
Georg Brandlccadf842006-03-31 18:54:53 +0000854- Patch #1460496: round() now accepts keyword arguments.
855
Anthony Baxter262c00a2006-03-30 10:53:17 +0000856- Fixed bug #1459029 - unicode reprs were double-escaped.
857
Hye-Shik Changd478f342006-03-23 12:32:36 +0000858- Patch #1396919: The system scope threads are reenabled on FreeBSD
859 5.4 and later versions.
860
Neal Norwitze98ccf62006-03-23 05:39:47 +0000861- Bug #1115379: Compiling a Unicode string with an encoding declaration
862 now gives a SyntaxError.
863
Georg Brandlabd1ff82006-03-18 07:59:59 +0000864- Previously, Python code had no easy way to access the contents of a
865 cell object. Now, a ``cell_contents`` attribute has been added
866 (closes patch #1170323).
867
Tim Peterscf79aac2006-03-16 01:14:46 +0000868- Patch #1123430: Python's small-object allocator now returns an arena to
869 the system ``free()`` when all memory within an arena becomes unused
870 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
871 freed. Some applications will see a drop in virtual memory size now,
872 especially long-running applications that, from time to time, temporarily
873 use a large number of small objects. Note that when Python returns an
874 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000875 platform C library will in turn return that memory to the operating system.
876 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000877 appears to be effective at least on Microsoft C and gcc-based systems.
878 Thanks to Evan Jones for hard work and patience.
879
Georg Brandl533ff6f2006-03-08 18:09:27 +0000880- Patch #1434038: property() now uses the getter's docstring if there is
881 no "doc" argument given. This makes it possible to legitimately use
882 property() as a decorator to produce a read-only property.
883
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000884- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
885 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
886 of requiring an int or long in slicing and a few other contexts, enabling
887 other objects (e.g. Numeric Python's integers) to be used as slice indices.
888
Neal Norwitz995acdf2006-03-07 05:01:00 +0000889- Fixed various bugs reported by Coverity's Prevent tool.
890
Brett Cannonbf364092006-03-01 04:25:17 +0000891- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
892 new exception base class, BaseException, which has a new message attribute.
893 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
894 Raising a string exception now raises a DeprecationWarning.
895
Thomas Woutersfb609f42006-02-28 16:37:25 +0000896- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
897 explicitly relative, using 'from .module import name' to mean 'from the same
898 package as this module is in. Imports without dots still default to the
899 old relative-then-absolute, unless 'from __future__ import
900 absolute_import' is used.
901
Brett Cannona7446e32006-02-27 23:39:10 +0000902- Properly check if 'warnings' raises an exception (usually when a filter set
903 to "error" is triggered) when raising a warning for raising string
904 exceptions.
905
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000906- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000907 The name was removed from Include/code.h.
908
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000909- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000910
Guido van Rossum1968ad32006-02-25 22:38:04 +0000911- Patch 1433928:
912 - The copy module now "copies" function objects (as atomic objects).
913 - dict.__getitem__ now looks for a __missing__ hook before raising
914 KeyError.
915
Tim Peters84ef21c2006-02-28 20:39:06 +0000916- PEP 343: with statement implemented. Needs ``from __future__ import
917 with_statement``. Use of 'with' as a variable will generate a warning.
918 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000919 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000920 The following objects have __context__ methods:
921 - The built-in file type.
922 - The thread.LockType type.
923 - The following types defined by the threading module:
924 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
925 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000926
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000927- Fix the encodings package codec search function to only search
928 inside its own package. Fixes problem reported in patch #1433198.
929
930 Note: Codec packages should implement and register their own
931 codec search function. PEP 100 has the details.
932
Tim Peters9ea89d22006-06-04 03:26:02 +0000933- PEP 353: Using ``Py_ssize_t`` as the index type.
934
935- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
936 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
937 now allow Python to make use of memory blocks exceeding 2**32 bytes for
938 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
939 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000940
Neal Norwitzfc76d632006-01-10 06:03:13 +0000941- Patch #1400181, fix unicode string formatting to not use the locale.
942 This is how string objects work. u'%f' could use , instead of .
943 for the decimal point. Now both strings and unicode always use periods.
944
Neal Norwitz671b9e32006-01-09 07:07:12 +0000945- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
946 configure would break checking curses.h.
947
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000948- Bug #959576: The pwd module is now builtin. This allows Python to be
949 built on UNIX platforms without $HOME set.
950
Neal Norwitzc10978f2005-12-19 06:07:16 +0000951- Bug #1072182, fix some potential problems if characters are signed.
952
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000953- Bug #889500, fix line number on SyntaxWarning for global declarations.
954
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000955- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
956
Neal Norwitze7214a12005-12-18 05:03:17 +0000957- Support for converting hex strings to floats no longer works.
958 This was not portable. float('0x3') now raises a ValueError.
959
Barry Warsaw2a38a862005-12-18 01:27:35 +0000960- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000961 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000962 is now displayed in interactive prompt banner.
963
Georg Brandlfa166682005-12-17 21:45:17 +0000964- Implementation of PEP 341 - Unification of try/except and try/finally.
965 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000966 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000967
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000968- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
969 now encodes backslash correctly.
970
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000971- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
972
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000973- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000974 and long longs.
975
Neal Norwitz67715f02005-11-09 06:59:35 +0000976- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000977 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000978 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000979
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000980- Replaced most Unicode charmap codecs with new ones using the
981 new Unicode translate string feature in the builtin charmap
982 codec; the codecs were created from the mapping tables available
983 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
984 encodings now include a mapping for the Apple logo)
985
Tim Peterse3547fd2005-12-16 23:13:57 +0000986- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000987
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000988- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000989
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000990- A new AST parser implementation was completed. The abstract
991 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000992 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000993
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000994- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000995 The following code now raises a SyntaxError: foo(a = i for i in range(10))
996
Neal Norwitz708e51a2005-10-03 04:48:15 +0000997- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
998
Neal Norwitz11bd1192005-10-03 00:54:56 +0000999- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1000 Provide a warning when a directory is passed on the command line.
1001
Neal Norwitz40d37812005-10-02 01:48:49 +00001002- Fix segfault with invalid coding.
1003
1004- SF bug #772896: unknown encoding results in MemoryError.
1005
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001006- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001007 supported a __len__() method which evaluated to False when the iterator
1008 was empty.
1009
Guido van Rossum630db602005-09-20 18:49:54 +00001010- On 64-bit platforms, when __len__() returns a value that cannot be
1011 represented as a C int, raise OverflowError.
1012
Skip Montanarof8948ca2005-09-19 03:54:46 +00001013- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001014 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001015
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001016- SF bug #893549: parsing keyword arguments was broken with a few format
1017 codes.
1018
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001019- Changes donated by Elemental Security to make it work on AIX 5.3
1020 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1021 bug #105470: test_pwd fails on 64bit system (Opteron).
1022
Guido van Rossum539c6622005-09-14 17:49:54 +00001023- Changes donated by Elemental Security to make it work on HP-UX 11 on
1024 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1025
Georg Brandl4550b8d2005-08-26 06:43:52 +00001026- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001027 (fixes bug #1119418).
1028
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001029- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1030
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001031- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1032 exceptions that cause a function to exit.
1033
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001034- The implementation of set() and frozenset() was revised to use its
1035 own internal data structure. Memory consumption is reduced by 1/3
1036 and there are modest speed-ups as well. The API is unchanged.
1037
Tim Petersde7990b2005-07-17 23:45:23 +00001038- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1039
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001040- SF bug #1229429: PyObject_CallMethod failed to decrement some
1041 reference counts in some error exit cases.
1042
Tim Petersecc6e6a2005-07-10 22:30:55 +00001043- SF bug #1185883: Python's small-object memory allocator took over
1044 a block managed by the platform C library whenever a realloc specified
1045 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001046 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001047 portable way to copy data from the C-managed block into Python's
1048 small-object space without risking a memory fault. Python's small-object
1049 realloc now leaves such blocks under the control of the platform C
1050 realloc.
1051
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001052- SF bug #1232517: An overflow error was not detected properly when
1053 attempting to convert a large float to an int in os.utime().
1054
Raymond Hettinger3296e692005-06-29 23:29:56 +00001055- SF bug #1224347: hex longs now print with lowercase letters just
1056 like their int counterparts.
1057
Michael W. Hudson188d4362005-06-20 16:52:57 +00001058- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1059 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1060 interpreter states; back out that fix and do a better job (see
1061 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1062 for a longer write-up of the problem).
1063
Michael W. Hudsondf888462005-06-03 14:41:55 +00001064- SF patch #1180995: marshal now uses a binary format by default when
1065 serializing floats.
1066
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001067- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1068 the routines that promise to produce IEEE 754 binary representations
1069 of floats now simply copy bytes around.
1070
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001071- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1072 278.
1073
Brett Cannonc3647ac2005-04-26 03:45:26 +00001074- patch #1109424: int, long, float, complex, and unicode now check for the
1075 proper magic slot for type conversions when subclassed. Previously the
1076 magic slot was ignored during conversion. Semantics now match the way
1077 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001078 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001079 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001080 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001081
Barry Warsawc8d907c2005-04-19 23:43:40 +00001082- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1083 NULL, now raise an AttributeError when attempting to set or delete the
1084 attribute. Previously a TypeError was raised, but this was inconsistent
1085 with the equivalent pure-Python implementation.
1086
Michael W. Hudson774479c2005-04-18 08:46:17 +00001087- It is now safe to call PyGILState_Release() before
1088 PyEval_InitThreads() (note that if there is reason to believe there
1089 are multiple threads around you still must call PyEval_InitThreads()
1090 before using the Python API; this fix is for extension modules that
1091 have no way of knowing if Python is multi-threaded yet).
1092
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001093- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1094 disabled caused a crash.
1095
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001096- Bug #1165306: instancemethod_new allowed the creation of a method
1097 with im_class == im_self == NULL, which caused a crash when called.
1098
Tim Petersecc6e6a2005-07-10 22:30:55 +00001099- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001100 fixes the crash seen in bug #1165761
1101
Raymond Hettinger96229b12005-03-11 06:49:40 +00001102- Added two new builtins, any() and all().
1103
Brett Cannon409d8f22005-03-05 06:47:57 +00001104- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001105 (e.g., ``class C(): pass`` is no longer a syntax error).
1106 Patch #1176012 added support to the 'parser' module and 'compiler' package
1107 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001108
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001109- Patch #1115086: Support PY_LONGLONG in structmember.
1110
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001111- Bug #1155938: new style classes did not check that __init__() was
1112 returning None.
1113
Tim Petersecc6e6a2005-07-10 22:30:55 +00001114- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001115 ('\') with a specific error message.
1116
Martin v. Löwisff232d72005-03-03 09:24:38 +00001117- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1118
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001119- Bug #1124295: the __name__ attribute of file objects was
1120 inadvertently made inaccessible in restricted mode.
1121
Tim Petersecc6e6a2005-07-10 22:30:55 +00001122- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001123 an ferror() call.
1124
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001125- min() and max() now support key= arguments with the same meaning as in
1126 list.sort().
1127
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001128- The peephole optimizer now performs simple constant folding in expressions:
1129 (2+3) --> (5).
1130
Raymond Hettingera422c342005-01-11 03:03:27 +00001131- set and frozenset objects can now be marshalled. SF #1098985.
1132
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001133- Bug #1077106: Poor argument checking could cause memory corruption
1134 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001135
Jeremy Hyltonab630502005-02-04 18:44:06 +00001136- The parser did not complain about future statements in illegal
1137 positions. It once again reports a syntax error if a future
1138 statement occurs after anything other than a doc string.
1139
Neil Schemenauercf52c072005-08-12 17:34:58 +00001140- Change the %s format specifier for str objects so that it returns a
1141 unicode instance if the argument is not an instance of basestring and
1142 calling __str__ on the argument returns a unicode instance.
1143
Tim Petersf4e69282006-02-27 17:15:31 +00001144- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1145 current thread state when the auto-GIL-state machinery knows about
1146 it (since the thread state is being deleted, continuing to remember it
1147 can't help, but can hurt if another thread happens to get created with
1148 the same thread id).
1149
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001150Extension Modules
1151-----------------
1152
Georg Brandl43f08a82006-03-31 18:01:16 +00001153- Patch #1380952: fix SSL objects timing out on consecutive read()s
1154
Neal Norwitz05a45592006-03-20 06:30:08 +00001155- Patch #1309579: wait3 and wait4 were added to the posix module.
1156
Anthony Baxterfa869072006-03-20 05:21:58 +00001157- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1158 In addition, the existing ulaw code was updated.
1159
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001160- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001161 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001162
Neal Norwitz10be10c2006-03-16 06:50:13 +00001163- Everything under lib-old was removed. This includes the following modules:
1164 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001165 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001166 util, whatsound, whrandom, zmod
1167
1168- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1169
1170- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001171 is deprecated. The undocumented re.engine variable no longer exists.
1172
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001173- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1174 SS2 (single-shift 2) escape sequences correctly.
1175
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001176- The unicodedata module was updated to the 4.1 version of the Unicode
1177 database. The 3.2 version is still available as unicodedata.db_3_2_0
1178 for applications that require this specific version (such as IDNA).
1179
Neal Norwitzb62c4332006-03-04 18:35:47 +00001180- The timing module is no longer built by default. It was deprecated
1181 in PEP 4 in Python 2.0 or earlier.
1182
Guido van Rossum1968ad32006-02-25 22:38:04 +00001183- Patch 1433928: Added a new type, defaultdict, to the collections module.
1184 This uses the new __missing__ hook behavior added to dict (see above).
1185
Georg Brandldbd83392006-02-20 09:42:33 +00001186- Bug #854823: socketmodule now builds on Sun platforms even when

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001340- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1341 been renamed to have only a single underscore prefix. This was done to
1342 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001343
Nick Coghlan43832302006-04-23 17:04:07 +00001344- PEP 338: new module runpy defines a run_module function to support
1345 executing modules which provide access to source code or a code object
1346 via the PEP 302 import mechanisms.
1347
Anthony Baxter93f5b932006-04-03 08:05:07 +00001348- The email module's parsedate_tz function now sets the daylight savings

1356 in attribute values.
1357
Anthony Baxterc51ee692006-04-01 00:57:31 +00001358- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001359 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001360 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001361 module will not be built.
1362
Tim Petersc17976e2006-04-01 00:26:53 +00001363- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1364 aren't officially supported here, and trying to use them will probably
1365 raise an exception some day. But dicts have been allowed, and "mostly
1366 worked", so support for them won't go away without warning.
1367
Georg Brandl338ef7d2006-03-31 18:42:16 +00001368- Bug #1445068: getpass.getpass() can now be given an explicit stream

1386
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001387- email 4.0 package now integrated. This is largely the same as the email 3.0
1388 package that was included in Python 2.3, except that PEP 8 module names are
1389 now used (e.g. mail.message instead of email.Message). The MIME classes
1390 have been moved to a subpackage (e.g. email.mime.text instead of
1391 email.MIMEText). The old names are still supported for now. Several
1392 deprecated Message methods have been removed and lots of bugs have been
1393 fixed. More details can be found in the email package documentation.
1394
Walter Dörwald40108c92006-03-27 08:15:44 +00001395- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1396 (a subclass of tuple) that provides incremental decoders and encoders
1397 (a way to use stateful codecs without the stream API). Python functions
1398 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1399 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1400 have been added.

1403 a ValueError instead of a StopIteration now (like file and cString.String do).
1404 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1405 called before (like file and StringIO.StringIO do).

1473
Neal Norwitz338e7862005-12-23 21:27:46 +00001474- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1475 LoadError as documented, instead of IOError. For compatibility,
1476 LoadError subclasses IOError.
1477
Brett Cannon3cbd0382005-12-16 22:49:23 +00001478- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001479 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1480 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1481 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1482 Ronald L. Rivest offered this advice for Python:
1483
1484 "The consensus of researchers in this area (at least as
1485 expressed at the NIST Hash Function Workshop 10/31/05),
1486 is that SHA-256 is a good choice for the time being, but
1487 that research should continue, and other alternatives may
1488 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001489
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001490- Added a subset of Fredrik Lundh's ElementTree package. Available

1543 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001544 correct line numbers for decoding errors in source code.

1567 to W3C name (404 -> 'Not Found'). RFE #1216944.
1568
Georg Brandl9e43acf2005-07-04 17:16:07 +00001569- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1570 as this can cause problems with apps closing all file descriptors.

1583 Bug #1224621.
1584
Raymond Hettinger68c04532005-06-10 11:05:19 +00001585- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001586 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001587 the generate_tokens() function now accepts a callable argument that
1588 terminates by raising StopIteration.
1589
Georg Brandl9166e1a2005-06-04 09:20:03 +00001590- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1594
Skip Montanaro174dd222005-05-14 20:54:16 +00001595- Patch #1120353: The xmlrpclib module provides better, more transparent,

1604 them to PyPI.
1605
Raymond Hettinger267b8682005-03-27 10:47:39 +00001606- decimal operator and comparison methods now return NotImplemented
1607 instead of raising a TypeError when interacting with other types. This
1608 allows other classes to implement __radd__ style methods and have them
1609 work as expected.
1610
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001611- Bug #1163325: Decimal infinities failed to hash. Attempting to
1612 hash a NaN raised an InvalidOperation instead of a TypeError.
1613
Tim Petersecc6e6a2005-07-10 22:30:55 +00001614- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1648
Guido van Rossumd0641422005-02-03 15:01:24 +00001649- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1650 disables recursive traversal through instance attributes, which can
1651 be exploited in various ways.
1652
Tim Peterse3547fd2005-12-16 23:13:57 +00001653- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001654 flags on the HTTP listening socket.
1655
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001656- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1657 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1658
Fred Drakefbdeaad2006-07-29 16:56:15 +00001659- Patches #893642, #1039083: add allow_none, encoding arguments to
1660 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001661

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001664- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1665
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001666- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1667
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001668- Enhancements to the csv module:
1669
1670 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001671 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001672 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001673 + Dialect parameter parsing has been re-implemented to improve error
1674 reporting.
1675 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1676 dictates.
1677 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001678 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001679 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001680 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1681 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001682 + reader now allows \r characters to be quoted (previously it only allowed
1683 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001684 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001685 + Dialect classes passed to the module are no longer instantiated by
1686 the module before being parsed (the former validation scheme required
1687 this, but the mechanism was unreliable).
1688 + The dialect registry now contains instances of the internal
1689 C-coded dialect type, rather than references to python objects.
1690 + the internal c-coded dialect type is now immutable.
1691 + register_dialect now accepts the same keyword dialect specifications
1692 as the reader and writer, allowing the user to register dialects
1693 without first creating a dialect class.
1694 + a configurable limit to the size of parsed fields has been added -
1695 previously, an unmatched quote character could result in the entire
1696 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001697 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001698 the parser field size limit (returning the former limit). The initial
1699 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001700 + A line_num attribute has been added to the reader object, which tracks
1701 the number of lines read from the source iterator. This is not
1702 the same as the number of records returned, as records can span
1703 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001704 + reader and writer objects were not being registered with the cyclic-GC.
1705 This has been fixed.
1706
Brett Cannone6539c42005-01-08 02:43:53 +00001707- _DummyThread objects in the threading module now delete self.__block that is
1708 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1709 lock primitives tend to be limited in number and thus should not be wasted on
1710 a _DummyThread object. Fixes bug #1089632.
1711
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001712- The imghdr module now detects Exif files.
1713
Raymond Hettinger6065d322004-12-20 23:51:53 +00001714- StringIO.truncate() now correctly adjusts the size attribute.
1715 (Bug #951915).
1716
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001717- locale.py now uses an updated locale alias table (built using
1718 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1719 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001720 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001721
Raymond Hettinger3557f422004-12-07 12:02:02 +00001722- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1723
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001724- the pickle module no longer accepts the deprecated None option in the
1725 args tuple returned by __reduce__().
1726
Brett Cannon84667c02004-12-07 03:25:18 +00001727- optparse now optionally imports gettext. This allows its use in setup.py.
1728
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001729- the pickle module no longer uses the deprecated bin parameter.
1730
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001731- the shelve module no longer uses the deprecated binary parameter.
1732

1734
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001735- the filecmp module no longer uses the deprecated use_statcache argument.
1736
Raymond Hettinger664347b2004-12-04 21:21:53 +00001737- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1738 extended or overridden by subclasses. Formerly, the subclassed method would
1739 be ignored by the rest of the module. (Bug #1078905).
1740
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001741- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001742 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001743
Walter Dörwald36733692004-12-22 12:50:50 +00001744- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1745 once when a size argument is given. This prevents a buffer overflow in the
1746 tokenizer with very long source lines.
1747
Barry Warsaw538561e2006-01-01 21:48:54 +00001748- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1749 immediately after creating the object, without any intervening
1750 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001751
Skip Montanaro05885812005-01-16 20:48:27 +00001752- The reconvert.quote function can now emit triple-quoted strings. The
1753 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001754
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001755- ``UserString.MutableString`` now supports negative indices in
1756 ``__setitem__`` and ``__delitem__``
1757
Greg Ward40407942005-03-05 02:53:17 +00001758- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1759 correctly.
1760
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001761- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1762 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1763 character even if the user has passed a size parameter to get a proper
1764 line ending. Remove the special handling of a "\r\n" that has been split
1765 between two lines.
1766
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001767- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1768 about illegal code points. The codec now supports PEP 293 style error
1769 handlers.
1770
Walter Dörwald78a78b02005-09-01 12:04:29 +00001771- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001772 from the input stream, so that the output is a byte string in the correct
1773 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001774
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001775- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1776 considering it exactly like a '*'.
1777
Walter Dörwald007f8df2005-10-09 19:42:27 +00001778- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1779 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001780
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001781- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1782
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001783- Patch #1413711: Certain patterns of differences were making difflib
1784 touch the recursion limit.
1785
Walter Dörwald58917a62006-03-31 15:26:22 +00001786- Bug #947906: An object oriented interface has been added to the calendar
1787 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001788 called as a script (e.g. via ``python -mcalendar``). Localized month and
1789 weekday names can be ouput (even if an exotic encoding is used) using
1790 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001792Build
1793-----
1794
Neal Norwitz602d3392006-03-31 08:21:40 +00001795- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1796 by using -mieee gcc option.
1797

1799
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001800- Build support for Win64-AMD64 was added.
1801
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001802- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1803
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001804- Patch #881820: look for openpty and forkpty also in libbsd.
1805
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001806- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1807 The zlib module is now builtin on Windows.
1808
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001809- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1810
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001811- Bug #1189330: configure did not correctly determine the necessary
1812 value of LINKCC if python was built with GCC 4.0.
1813
Trent Mick8321b422005-07-26 02:29:21 +00001814- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1815 vulnerability in zlib 1.2.1 and 1.2.2.
1816
Brett Cannon08cd5982005-04-24 22:26:38 +00001817- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1818 flags that change binary compatibility. Changes were also made to
1819 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001820 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001821
Bob Ippolitoed233462005-03-29 13:47:59 +00001822- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1823 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1824 no longer exists). This configure patch makes things right.
1825
Martin v. Löwise2713be2005-03-08 15:03:08 +00001826- Bug #1158607: Build with --disable-unicode again.
1827
Brett Cannon46d96232005-02-16 00:07:19 +00001828- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1829 defined. Discovered as a result of not being able to build on OS X.
1830
Brett Cannon516592f2004-12-07 00:42:59 +00001831- setup.py now uses the directories specified in LDFLAGS using the -L option
1832 and in CPPFLAGS using the -I option for adding library and include
1833 directories, respectively, for compiling extension modules against. This has
1834 led to the core being compiled using the values in CPPFLAGS. It also removes
1835 the need for the special-casing of both DarwinPorts and Fink for darwin since
1836 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1837 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1838 Fink, ``-I/opt/local/include`` for DarwinPorts).
1839
Brett Cannon43802422005-02-10 20:48:03 +00001840- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1841 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1842 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1843 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001845C API
1846-----
1847
Tim Petersc9d78aa2006-03-26 23:27:58 +00001848- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1849 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1850 is obtained via the ``PyObject_`` family, it must be released via the
1851 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1852 always been officially true, but when Python's small-object allocator was
1853 introduced, an attempt was made to cater to a few extension modules
1854 discovered at the time that obtained memory via ``PyObject_New`` but
1855 released it via ``PyMem_DEL``. It's years later, and if such code still
1856 exists it will fail now (probably with segfaults, but calling wrong
1857 low-level memory management functions can yield many symptoms).
1858
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001859- Added a C API for set and frozenset objects.
1860
Raymond Hettinger66517482004-12-03 11:45:13 +00001861- Removed PyRange_New().
1862
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001863- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1864 mapping argument now. This string is used as a mapping table. Byte values
1865 greater than the length of the string and 0xFFFE are treated as undefined
1866 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001873
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001874- Patch #1276356: New resource "urlfetch" is implemented. This enables
