Fred Drake53912162006-07-29 13:22:49 +00007What's New in Python 2.5 beta 3?
8================================
Neal Norwitza1f10902006-07-12 07:28:29 +00009
10*Release date: XX-AUG-2006*
11
12Core and builtins
13-----------------
14
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000015- Bug #1515471: string.replace() accepts character buffers again.
16
Neal Norwitz07aadb12006-07-30 06:55:48 +000017- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
18 This provides the proper warning for struct.pack().
19 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
20
Neal Norwitz0d62a062006-07-30 06:53:31 +000021- Patch #1531113: Fix augmented assignment with yield expressions.
22 Also fix a SystemError when trying to assign to yield expressions.
23
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000024- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
25 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
26 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
27 excessive filesystem operations during imports.
28
Tim Petersbc24eee2006-07-27 01:14:53 +000029- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
30 operations on signed longs that are formally undefined by C.
31 Unfortunately, at least one compiler now cares about that, so complicated
32 the code to make that compiler happy again.
33
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000034- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
35
Martin v. Löwisd22968a2006-07-24 11:54:53 +000036- Patch #1232023: Stop including current directory in search
37 path on Windows.
38
Neal Norwitze1fdb322006-07-21 05:32:28 +000039- Fix some potential crashes found with failmalloc.
40
Neal Norwitze7563102006-07-17 01:00:16 +000041- Fix warnings reported by Klocwork's static analysis tool.
42
Neal Norwitz84be93b2006-07-16 01:50:38 +000043- Bug #1512814, Fix incorrect lineno's when code within a function
44 had more than 255 blank lines.
45
Georg Brandl9dceedb2006-07-12 15:31:17 +000046- Patch #1521179: Python now accepts the standard options ``--help`` and
47 ``--version`` as well as ``/?`` on Windows.
48
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000049- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000050 again. Fixing this problem required changing the .pyc magic number.
51 This means that .pyc files generated before 2.5c1 will be regenerated.
52
Tim Peters112aad32006-07-19 00:03:19 +000053- Bug #1524317: Compiling Python ``--without-threads`` failed.
54 The Python core compiles again then, and, in a build without threads, the
55 new ``sys._current_frames()`` returns a dictionary with one entry,
56 mapping the faux "thread id" 0 to the current frame.
57
Ronald Oussoren3075e162006-07-25 20:28:55 +000058- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000059
Ronald Oussoren3075e162006-07-25 20:28:55 +000060
Neal Norwitza1f10902006-07-12 07:28:29 +000061Library
62-------
63
Martin v. Löwis4e678382006-07-30 13:00:31 +000064- Bug #1525866: Don't copy directory stat times in
65 shutil.copytree on Windows
66
Georg Brandle34ac7c2006-07-30 11:07:23 +000067- Bug #1002398: The documentation for os.path.sameopenfile now correctly
68 refers to file descriptors, not file objects.
69
Fred Drakefbdeaad2006-07-29 16:56:15 +000070- Rename of the xml package to xmlcore, and the import hackery done to
71 make it appear at both names, has been removed. Bug #1511497,
72 #1513611, and probably others.
73
Georg Brandledd9b0d2006-07-29 09:33:26 +000074- Bug #1441397: The compiler module now recognizes module and function
75 docstrings correctly as it did in Python 2.4.
76
Tim Peters6f681472006-07-27 23:44:37 +000077- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
78 lost that tests are sorted by name before being run. This rarely
79 matters for well-written tests, but can create baffling symptoms if
80 side effects from one test to the next affect outcomes. ``DocTestFinder``
81 has been changed to sort the list of tests it returns.
82
Martin v. Löwis997ceff2006-07-27 06:38:16 +000083- The distutils version has been changed to 2.5.0.
84
Martin v. Löwis9298eff2006-07-26 12:12:56 +000085- Bug #978833: Really close underlying socket in _socketobject.close.
86
Georg Brandl0619a322006-07-26 07:40:17 +000087- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
88 with title().
89
Georg Brandlcf0c1722006-07-26 07:23:32 +000090- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
91 to recursive calls and call it with the failing package name.
92
Martin v. Löwis0b483032006-07-25 09:53:12 +000093- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
94
Georg Brandlc13c34c2006-07-24 14:09:56 +000095- Patch #1515343: Fix printing of deprecated string exceptions with a
96 value in the traceback module.
97
Greg Ward48fae7a2006-07-23 16:05:51 +000098- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
99
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000100- Patch #1524429: Use repr() instead of backticks in Tkinter again.
101
Brett Cannoncaebe222006-07-18 04:41:36 +0000102- Bug #1520914: Change time.strftime() to accept a zero for any position in its
103 argument tuple. For arguments where zero is illegal, the value is forced to
104 the minimum value that is correct. This is to support an undocumented but
105 common way people used to fill in inconsequential information in the time
106 tuple pre-2.4.
107
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000108- Patch #1220874: Update the binhex module for Mach-O.
109
Barry Warsawb110bad2006-07-21 14:51:07 +0000110- The email package has improved RFC 2231 support, specifically for
111 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
112 (name*0=<blah>) parameter continuations. This may change the types of
113 values returned from email.message.Message.get_param() and friends.
114 Specifically in some cases where non-encoded continuations were used,
115 get_param() used to return a 3-tuple of (None, None, string) whereas now it
116 will just return the string (since non-encoded continuations don't have
117 charset and language parts).
118
119 Also, whereas % values were decoded in all parameter continuations, they are
120 now only decoded in encoded parameter parts.
121
Ronald Oussoren3075e162006-07-25 20:28:55 +0000122- Bug #1517990: IDLE keybindings on MacOS X now work correctly
123
124- Bug #1517996: IDLE now longer shows the default Tk menu when a
125 path browser, class browser or debugger is the frontmost window on MacOS X
126
Barry Warsaw00decd72006-07-27 23:43:15 +0000127- Patch #1520294: Support for getset and member descriptors in types.py,
128 inspect.py, and pydoc.py. Specifically, this allows for querying the type
129 of an object against these built-in types and more importantly, for getting
130 their docstrings printed in the interactive interpreter's help() function.
131
Ronald Oussoren3075e162006-07-25 20:28:55 +0000132
Neal Norwitza1f10902006-07-12 07:28:29 +0000133Extension Modules
134-----------------
135
Thomas Heller1393d6a2006-07-28 21:43:20 +0000136- Patch #1529514: The _ctypes extension is now compiled on more
137 openbsd target platforms.
138
Tim Peters9cab5932006-07-28 00:30:00 +0000139- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
140 a memory leak, affecting pickles and deep copies.
141
Tim Petersbc24eee2006-07-27 01:14:53 +0000142- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000143 Paul Eggert.
144

146
Thomas Hellerce049a02006-07-14 17:51:14 +0000147- Patch #1521817: Index range checking on ctypes arrays containing
148 exactly one element enabled again. This allows iterating over these
149 arrays, without the need to check the array size before.
150
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000151- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000152 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000153 /dev/null in certain cases; this is now fixed.
154
Thomas Heller47d7a062006-07-12 08:43:47 +0000155- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
156 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000157
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000158- Because of a misspelled preprocessor symbol, ctypes was always
159 compiled without thread support; this is now fixed.
160
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000161- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
162 methods now allow their database parameter to be None as the
163 sleepycat API allows.
164
Matt Flemingec926502006-07-28 11:27:27 +0000165- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
166 bluetooth API compared with Linux and FreeBSD.
167
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000168Tests
169-----
170
171- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
172 how long the test file should take to play. Now accepts taking 2.93 secs
173 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
174
Georg Brandl4793aa32006-07-28 18:31:39 +0000175- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
176 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
177 run via ``regrtest.py``. Now they do.

Georg Brandlad29e632006-06-21 17:45:17 +0000184
185Core and builtins
186-----------------
187
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000188- Bug #1441486: The literal representation of -(sys.maxint - 1)
189 again evaluates to a int object, not a long.
190
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000191- Bug #1501934: The scope of global variables that are locally assigned
192 using augmented assignment is now correctly determined.
193
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000194- Bug #927248: Recursive method-wrapper objects can now safely
195 be released.
196
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000197- Bug #1417699: Reject locale-specific decimal point in float()
198 and atof().
199
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000200- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
201 omit a default "error" argument for NULL pointer. This allows
202 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000203
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000204- Bug #1519018: 'as' is now validated properly in import statements.
205
Neal Norwitz28746ab2006-07-09 22:14:42 +0000206- On 64 bit systems, int literals that use less than 64 bits are
207 now ints rather than longs.
208
Neal Norwitzed657552006-07-10 00:04:44 +0000209- Bug #1512814, Fix incorrect lineno's when code at module scope
210 started after line 256.
211
Tim Peters32a83612006-07-10 21:08:24 +0000212- New function ``sys._current_frames()`` returns a dict mapping thread
213 id to topmost thread stack frame. This is for expert use, and is
214 especially useful for debugging application deadlocks. The functionality
215 was previously available in Fazal Majid's ``threadframe`` extension
216 module, but it wasn't possible to do this in a wholly threadsafe way from
217 an extension.
218
Georg Brandlad29e632006-06-21 17:45:17 +0000219Library
220-------
221

Tim Peters32a83612006-07-10 21:08:24 +0000224- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000225 environment variable to be set in order to the SDK environment
226 for finding the compiler, include files, etc.
227
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000228- Bug #1515998: Properly generate logical ids for files in bdist_msi.

231
Thomas Woutersadd19112006-07-05 11:03:49 +0000232- string.Template() now correctly handles tuple-values. Previously,
233 multi-value tuples would raise an exception and single-value tuples would
234 be treated as the value they contain, instead.
235
Martin v. Löwisede77f52006-07-03 13:01:35 +0000236- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
237 even if some data are received.
238
Martin v. Löwis45482392006-07-03 12:28:58 +0000239- Bug #1267547: Put proper recursive setup.py call into the
240 spec file generated by bdist_rpm.
241

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000246 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000247
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000248- Bug #1514703: Only setup canvas window in turtle when the canvas
249 is created.
250

258 sgmllib ('[' and ']' were not accepted).
259
Georg Brandl1be63af2006-06-28 20:23:25 +0000260- Fix a bug in the turtle module's end_fill function.
261
Brett Cannon53ab5b72006-06-22 16:49:14 +0000262- Bug #1510580: The 'warnings' module improperly required that a Warning
263 category be either a types.ClassType and a subclass of Warning. The proper
264 check is just that it is a subclass with Warning as the documentation states.
265
Georg Brandlad29e632006-06-21 17:45:17 +0000266- The compiler module now correctly compiles the new try-except-finally
267 statement (bug #1509132).
268
Neal Norwitz60373cd2006-06-22 06:30:50 +0000269- The wsgiref package is now installed properly on Unix.
270
Vinay Sajip28e57612006-07-01 10:45:20 +0000271- A bug was fixed in logging.config.fileConfig() which caused a crash on
272 shutdown when fileConfig() was called multiple times.
273
Gerhard Häring762fbd32006-07-02 17:48:30 +0000274- The sqlite3 module did cut off data from the SQLite database at the first
275 null character before sending it to a custom converter. This has been fixed
276 now.
277
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000278Extension Modules
279-----------------
280
Tim Peters112aad32006-07-19 00:03:19 +0000281- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
282 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
283 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000284
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000285- Assigning None to pointer type fields in ctypes structures possible
286 overwrote the wrong fields, this is fixed now.
287
288- Fixed a segfault in _ctypes when ctypes.wintypes were imported
289 on non-Windows platforms.
290
291- Bug #1518190: The ctypes.c_void_p constructor now accepts any
292 integer or long, without range checking.
293
294- Patch #1517790: It is now possible to use custom objects in the ctypes
295 foreign function argtypes sequence as long as they provide a from_param
296 method, no longer is it required that the object is a ctypes type.
297
298- The '_ctypes' extension module now works when Python is configured
299 with the --without-threads option.
300
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000301- Bug #1513646: os.access on Windows now correctly determines write
302 access, again.
303
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000304- Bug #1512695: cPickle.loads could crash if it was interrupted with
305 a KeyboardInterrupt.
306
Neal Norwitza12aa882006-07-06 06:45:08 +0000307- Bug #1296433: parsing XML with a non-default encoding and
308 a CharacterDataHandler could crash the interpreter in pyexpat.
309
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000310- Patch #1516912: improve Modules support for OpenVMS.

316
Tim Peters32a83612006-07-10 21:08:24 +0000317- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000318 Previously, the slight difference could cause compilation errors of the
319 'zlib' module on systems with more than one version of zlib.
320
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000321- The MSI compileall step was fixed to also support a TARGETDIR
322 with spaces in it.
323

325 of Tcl/Tk.
326
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000327- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old

Anthony Baxter51bcb682006-04-05 14:51:42 +0000348
Anthony Baxterd1136802006-06-19 12:04:15 +0000349*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000350
351Core and builtins
352-----------------
353
Georg Brandla56b9152006-06-19 06:35:54 +0000354- Patch #1507676: Error messages returned by invalid abstract object operations
355 (such as iterating over an integer) have been improved and now include the
356 type of the offending object to help with debugging.
357
Brett Cannonea3912b2006-06-13 21:46:41 +0000358- Bug #992017: A classic class that defined a __coerce__() method that returned
359 its arguments swapped would infinitely recurse and segfault the interpreter.
360
Neal Norwitz909eb122006-06-12 02:13:21 +0000361- Fix the socket tests so they can be run concurrently.
362
Neal Norwitzb9845e72006-06-12 02:11:18 +0000363- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000364 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000365
Brett Cannon22565aa2006-06-09 22:31:23 +0000366- Bug #532646: object.__call__() will continue looking for the __call__
367 attribute on objects until one without one is found. This leads to recursion
368 when you take a class and set its __call__ attribute to an instance of the
369 class. Originally fixed for classic classes, but this fix is for new-style.
370 Removes the infinite_rec_3 crasher.
371
Georg Brandl24250812006-06-09 18:45:48 +0000372- The string and unicode methods startswith() and endswith() now accept
373 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
374
Brett Cannonde3b0522006-06-08 17:00:45 +0000375- Buffer objects, at the C level, never used the char buffer
376 implementation even when the char buffer for the wrapped object was
377 explicitly requested (originally returned the read or write buffer).
378 Now a TypeError is raised if the char buffer is not present but is
379 requested.
380
Georg Brandlddbaa662006-06-04 21:56:52 +0000381- Patch #1346214: Statements like "if 0: suite" are now again optimized
382 away like they were in Python 2.4.
383
Georg Brandlb7c8f542006-05-27 12:30:25 +0000384- Builtin exceptions are now full-blown new-style classes instead of
385 instances pretending to be classes, which speeds up exception handling
386 by about 80% in comparison to 2.5a2.
387
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000388- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
389 Unicode 4.1.
390
Georg Brandlf4ef1162006-05-26 18:03:31 +0000391- Patch #921466: sys.path_importer_cache is now used to cache valid and
392 invalid file paths for the built-in import machinery which leads to
393 fewer open calls on startup.
394
Tim Peters696cf432006-05-24 21:10:40 +0000395- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
396 of-2 bases. The largest speedup is for inputs with about 1000 decimal
397 digits. Conversion from non-power-of-2 bases remains quadratic-time in
398 the number of input digits (it was and remains linear-time for bases
399 2, 4, 8, 16 and 32).
400
Tim Petersb713ec22006-05-23 18:45:30 +0000401- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
402 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
403 an integer close to ``sys.maxint``. This was repaired by patch
404 #1335972, which also gives a nice speedup.
405
Richard Jonescebbefc2006-05-23 18:28:17 +0000406- Patch #1337051: reduced size of frame objects.
407
408- PyErr_NewException now accepts a tuple of base classes as its
409 "base" parameter.
410
Richard Jones7c88dcc2006-05-23 10:37:38 +0000411- Patch #876206: function call speedup by retaining allocated frame
412 objects.
413
Georg Brandl7b90e162006-05-18 07:01:27 +0000414- Bug #1462152: file() now checks more thoroughly for invalid mode
415 strings and removes a possible "U" before passing the mode to the
416 C library function.
417
Neal Norwitz1004a532006-05-15 07:17:23 +0000418- Patch #1488312, Fix memory alignment problem on SPARC in unicode
419
Neal Norwitz373f0a72006-05-15 07:04:36 +0000420- Bug #1487966: Fix SystemError with conditional expression in assignment
421
Martin v. Löwis879768d2006-05-11 13:28:43 +0000422- WindowsError now has two error code attributes: errno, which carries
423 the error values from errno.h, and winerror, which carries the error
424 values from winerror.h. Previous versions put the winerror.h values
425 (from GetLastError()) into the errno attribute.
426
Martin v. Löwis77736712006-05-04 05:51:03 +0000427- Patch #1475845: Raise IndentationError for unexpected indent.
428
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000429- Patch #1479181: split open() and file() from being aliases for each other.
430
Tim Peters44bd9862006-06-01 13:49:23 +0000431- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
432 methods were always silently ignored by dictionaries when comparing keys.
433 They are now passed through (except when using the C API function
434 ``PyDict_GetItem()``, whose semantics did not change).
435
436- Bug #1456209: In some obscure cases it was possible for a class with a
437 custom ``__eq__()`` method to confuse dict internals when class instances
438 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
439 No, you don't have any code that did this ;-)

445
446- Patch #1462338: Upgrade pyexpat to expat 2.0.0
447
Brett Cannon6ee7d012006-06-08 16:23:04 +0000448- Change binascii.hexlify to accept a read-only buffer instead of only a char
449 buffer and actually follow its documentation.
450
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000451- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
452
Nick Coghlanc649ec52006-05-29 12:43:05 +0000453- Patch #1478788 (modified version): The functional extension module has
454 been renamed to _functools and a functools Python wrapper module added.
455 This provides a home for additional function related utilities that are
456 not specifically about functional programming. See PEP 309.
457
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000458- Patch #1493701: performance enhancements for struct module.
459
Georg Brandl378d5922006-05-17 14:26:50 +0000460- Patch #1490224: time.altzone is now set correctly on Cygwin.
461
Georg Brandl8d3342b2006-05-16 07:38:27 +0000462- Patch #1435422: zlib's compress and decompress objects now have a
463 copy() method.
464
Andrew MacIntyre92913322006-06-13 15:04:24 +0000465- Patch #1454481: thread stack size is now tunable at runtime for thread
466 enabled builds on Windows and systems with Posix threads support.
467
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000468- On Win32, os.listdir now supports arbitrarily-long Unicode path names
469 (up to the system limit of 32K characters).
470
471- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
472 As a result, these functions now raise WindowsError instead of OSError.
473
Tim Peters7a822da2006-05-25 21:50:17 +0000474- ``time.clock()`` on Win64 should use the high-performance Windows
475 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
476 Windows platforms).
477
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000478- Calling Tk_Init twice is refused if the first call failed as that
479 may deadlock.
480
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000481- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
482 accept it without potentially using an uninitialized pointer.
483
484- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
485 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
486 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000487
Gregory P. Smith372b5832006-06-05 18:48:21 +0000488- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000489 [pybsddb project SF patch number 1466734]
490
Gregory P. Smith372b5832006-06-05 18:48:21 +0000491- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
492 parameter is supplied. [SF pybsddb bug #1477863]
493
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000494- bsddb: the __len__ method of a DB object has been fixed to return correct
495 results. It could previously incorrectly return 0 in some cases.
496 Fixes SF bug 1493322 (pybsddb bug 1184012).
497
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000498- bsddb: the bsddb.dbtables Modify method now raises the proper error and
499 aborts the db transaction safely when a modifier callback fails.
500 Fixes SF python patch/bug #1408584.
501
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000502- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000503 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000504 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
505 database calls that would previously deadlock. [SF python bug #775414]
506
Vinay Sajip28e57612006-07-01 10:45:20 +0000507- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000508

514
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000515- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
516 functions.
517
Martin v. Löwis3798da02006-06-17 18:44:27 +0000518- Patch #812986: Update turtle output even if not tracing.
519
Vinay Sajip28e57612006-07-01 10:45:20 +0000520- Patch #1494750: Destroy master after deleting children in

522
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000523- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
524
Martin v. Löwis337487e2006-06-17 09:15:14 +0000525- Patch #763580: Add name and value arguments to Tkinter variable
526 classes.
527
Georg Brandl83cc0d02006-06-14 08:50:03 +0000528- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
529 mime.types file for determining MIME types.
530
Georg Brandl2605ca82006-06-14 06:08:31 +0000531- Bug #1339007: Shelf objects now don't raise an exception in their
532 __del__ method when initialization failed.
533
Martin v. Löwisd8251432006-06-14 05:21:04 +0000534- Patch #1455898: The MBCS codec now supports the incremental mode for
535 double-byte encodings.
536
Tim Peters43898b42006-06-14 04:09:25 +0000537- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
538 guarantee that adjacent triples in the return list always describe
539 non-adjacent blocks. Previously, a pair of matching blocks could end
540 up being described by multiple adjacent triples that formed a partition
541 of the matching pair.
542
Greg Ward0e0c9f42006-06-11 16:24:11 +0000543- Bug #1498146: fix optparse to handle Unicode strings in option help,
544 description, and epilog.
545
Greg Wardd1c797e2006-06-11 14:42:41 +0000546- Bug #1366250: minor optparse documentation error.
547
Greg Ward7f547402006-06-11 00:40:49 +0000548- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
549 clarify docs.
550
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000551- The wsgiref package has been added to the standard library.
552
Nick Coghlan676725d2006-06-08 13:54:49 +0000553- The functions update_wrapper() and wraps() have been added to the functools
554 module. These make it easier to copy relevant metadata from the original
555 function when writing wrapper functions.
556
Tim Petersd6a9eef2006-06-05 01:48:21 +0000557- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
558 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000559
Martin v. Löwis3f767792006-06-04 19:36:28 +0000560- Patch #1359618: Speed up charmap encoder by using a trie structure
561 for lookup.
562
Tim Petersd609b1a2006-06-02 23:22:51 +0000563- The functions in the ``pprint`` module now sort dictionaries by key
564 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
565 if and only if its display required more than one line, although that
566 wasn't documented. The new behavior increases predictability; e.g.,
567 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
568
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000569- Patch #1497027: try HTTP digest auth before basic auth in urllib2
570 (thanks for J. J. Lee).
571
Georg Brandl2b330372006-05-28 20:23:12 +0000572- Patch #1496206: improve urllib2 handling of passwords with respect to
573 default HTTP and HTTPS ports.
574
George Yoshidaf3c65de2006-05-28 16:39:09 +0000575- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
576
Bob Ippolito7298f272006-05-23 18:43:47 +0000577- Patch #1281707: speed up gzip.readline.
578
Georg Brandlb89316f2006-05-17 15:51:16 +0000579- Patch #1180296: Two new functions were added to the locale module:
580 format_string() to get the effect of "format % items" but locale-aware,
581 and currency() to format a monetary number with currency sign.
582
Georg Brandle3a25832006-05-17 14:56:04 +0000583- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
584 and several features added, such as speed and geometry control.
585
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000586- Patch #1488881: add support for external file objects in bz2 compressed
587 tarfiles.
588
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000589- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
590 stdout arguments, making it possible to redirect input and output
591 for remote debugging.
592
593- Patch #1484695: Update the tarfile module to version 0.8. This fixes
594 a couple of issues, notably handling of long file names using the
595 GNU LONGNAME extension.
596
597- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
598 new flag when ``name`` is already the name of an option flag.
599
600- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
601 package.
602
603- Patch #1472854: make the rlcompleter.Completer class usable on non-
604 UNIX platforms.
605
606- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
607
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000608- Bug #1472827: correctly escape newlines and tabs in attribute values in

Martin v. Löwis222c5152006-06-03 07:37:13 +0000617- OpenBSD 3.9 is supported now.
618
Martin v. Löwisa43190b2006-05-22 09:15:18 +0000619- Patch #1492356: Port to Windows CE.
620
Neal Norwitz58e28882006-05-19 07:00:58 +0000621- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000639What's New in Python 2.5 alpha 2?
640=================================
641
642*Release date: 27-APR-2006*
643
644Core and builtins
645-----------------
646
Thomas Heller1b046642006-04-18 18:51:06 +0000647- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
648 by converting these apis from macros into exported functions again:
649
650 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
651 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
652 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
653 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
654 PyRun_String Py_CompileString
655
Martin v. Löwis45294a92006-04-18 06:24:08 +0000656- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
657
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000658- All uses of PyStructSequence_InitType have been changed to initialize
659 the type objects only once, even if the interpreter is initialized
660 multiple times.
661
Neal Norwitz61546162006-04-14 05:20:28 +0000662- Bug #1454485, array.array('u') could crash the interpreter. This was
663 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
664 to unicode when it didn't make sense. 'u#' now requires a unicode string.
665
666- Py_UNICODE is unsigned. It was always documented as unsigned, but
667 due to a bug had a signed value in previous versions.
668
Tim Peters3a5e8b12006-04-11 01:44:07 +0000669- Patch #837242: ``id()`` of any Python object always gives a positive
670 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
671 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000672 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000673 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000674
Tim Peters3a5e8b12006-04-11 01:44:07 +0000675 def __hash__(self):
676 return id(self) # WRONG
677
678 because a hash result must be a (short) Python int but it was always
679 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000680 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000681 was always usable as a hash value before this patch. That's no longer
682 necessarily so.
683
684- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000685 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000686 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000687 #1454844)
688
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000689- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
690 involving generators that have paused outside of any ``try`` or ``with``
691 blocks. (In 2.5a1, a paused generator that was part of a reference
692 cycle could not be garbage collected, regardless of whether it was
693 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +0000694
Anthony Baxter51bcb682006-04-05 14:51:42 +0000695Extension Modules
696-----------------
697
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000698- Patch #1191065: Fix preprocessor problems on systems where recvfrom
699 is a macro.
700
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000701- Bug #1467952: os.listdir() now correctly raises an error if readdir()
702 fails with an error condition.
703
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000704- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
705
706- Bug #1117761: bsddb.*open() no longer raises an exception when using
707 the cachesize parameter.
708
709- Bug #1149413: bsddb.*open() no longer raises an exception when using
710 a temporary db (file=None) with the 'n' flag to truncate on open.
711
712- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
713 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000714
Armin Rigoa9017c32006-04-19 11:50:27 +0000715- Patch #1062014: AF_UNIX sockets under Linux have a special
716 abstract namespace that is now fully supported.
717
Anthony Baxter51bcb682006-04-05 14:51:42 +0000718Library
719-------
720
Peter Astrand7d1d4362006-07-14 14:04:45 +0000721- Bug #1223937: subprocess.CalledProcessError reports the exit status
722 of the process using the returncode attribute, instead of
723 abusing errno.
724
Tim Peters711bf302006-04-25 03:31:36 +0000725- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
726 a doctest to be skipped (the code is not run, and the expected output
727 or exception is ignored).
728
Nick Coghlanda2268f2006-04-24 04:37:15 +0000729- Fixed contextlib.nested to cope with exceptions being raised and
730 caught inside exit handlers.
731
Greg Wardab05edc2006-04-23 03:47:58 +0000732- Updated optparse module to Optik 1.5.1 (allow numeric constants in
733 hex, octal, or binary; add ``append_const`` action; keep going if
734 gettext cannot be imported; added ``OptionParser.destroy()`` method;
735 added ``epilog`` for better help generation).
736
Tim Peters21fbd572006-04-21 21:18:10 +0000737- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
738 called from a thread spawned as a side effect of importing a module.
739
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000740- The pydoc module now supports documenting packages contained in
741 .zip or .egg files.
742
743- The pkgutil module now has several new utility functions, such
744 as ``walk_packages()`` to support working with packages that are either
745 in the filesystem or zip files.
746
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000747- The mailbox module can now modify and delete messages from
748 mailboxes, in addition to simply reading them. Thanks to Gregory
749 K. Johnson for writing the code, and to the 2005 Google Summer of
750 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000751
Tim Petersc7605f22006-04-17 21:12:33 +0000752- The ``__del__`` method of class ``local`` in module ``_threading_local``
753 returned before accomplishing any of its intended cleanup.
754
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000755- Patch #790710: Add breakpoint command lists in pdb.
756
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000757- Patch #1063914: Add Tkinter.Misc.clipboard_get().
758
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000759- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
760
Anthony Baxtere29002c2006-04-12 12:07:31 +0000761- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
762 Windows. Bug #1469163.
763
Phillip J. Eby47032112006-04-11 01:07:43 +0000764- The warnings, linecache, inspect, traceback, site, and doctest modules
765 were updated to work correctly with modules imported from zipfiles or
766 via other PEP 302 __loader__ objects.
767
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000768- Patch #1467770: Reduce usage of subprocess._active to processes which
769 the application hasn't waited on.
770
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000771- Patch #1462222: Fix Tix.Grid.
772
Neal Norwitza31bf182006-04-09 03:35:43 +0000773- Fix exception when doing glob.glob('anything*/')
774
Skip Montanaro262fb922006-04-21 02:31:07 +0000775- The pstats.Stats class accepts an optional stream keyword argument to
776 direct output to an alternate file-like object.
777
Anthony Baxter51bcb682006-04-05 14:51:42 +0000778Build
779-----
780
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000781- The Makefile now has a reindent target, which runs reindent.py on
782 the library.
783
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000784- Patch #1470875: Building Python with MS Free Compiler
785
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000786- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000787
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000788- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
789 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000790 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000791 CXX from --with-cxx-main, see description in README.
792
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000793- Patch #1429775: Link extension modules with the shared libpython.
794
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000795- Fixed a libffi build problem on MIPS systems.
796
Tim Peters8931ff12006-05-13 23:28:20 +0000797- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
798 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
799 and "%zu" for unsigned integers of type ``size_t``.
800
Anthony Baxter51bcb682006-04-05 14:51:42 +0000801Tests
802-----
803
Nick Coghlanda2268f2006-04-24 04:37:15 +0000804- test_contextlib now checks contextlib.nested can cope with exceptions
805 being raised and caught inside exit handlers.
806
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000807- test_cmd_line now checks operation of the -m and -c command switches
808
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000809- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
810 it separately and by hand. It also wasn't cleaning up its changes to
811 the current Decimal context.
812
Thomas Woutersabd08882006-04-26 15:53:30 +0000813- regrtest.py now has a -M option to run tests that test the new limits of
814 containers, on 64-bit architectures. Running these tests is only sensible
815 on 64-bit machines with more than two gigabytes of memory. The argument
816 passed is the maximum amount of memory for the tests to use.

821- Added the Python benchmark suite pybench to the Tools/ directory;
822 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000824Documentation
825-------------
826
Tim Petersb06d28c2006-05-12 01:57:59 +0000827- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
828
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000829- PEP 343: Added Context Types section to the library reference
830 and attempted to bring other PEP 343 related documentation into
831 line with the implementation and/or python-dev discussions.
832
Tim Peters8dc73d22006-04-24 02:03:16 +0000833- Bug #1337990: clarified that ``doctest`` does not support examples
834 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000837What's New in Python 2.5 alpha 1?
838=================================
839
Anthony Baxterebed3f62006-04-03 15:03:44 +0000840*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000841
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000842Core and builtins
843-----------------
844
Nick Coghlan43832302006-04-23 17:04:07 +0000845- PEP 338: -m command line switch now delegates to runpy.run_module
846 allowing it to support modules in packages and zipfiles
847
Martin v. Löwisc661b882006-04-20 04:54:23 +0000848- On Windows, .DLL is not an accepted file name extension for
849 extension modules anymore; extensions are only found if they
850 end in .PYD.
851
Martin v. Löwisea62d252006-04-03 10:56:49 +0000852- Bug #1421664: sys.stderr.encoding is now set to the same value as
853 sys.stdout.encoding.
854
Neal Norwitz92e212f2006-04-03 04:48:37 +0000855- __import__ accepts keyword arguments.
856
Georg Brandlccadf842006-03-31 18:54:53 +0000857- Patch #1460496: round() now accepts keyword arguments.
858
Anthony Baxter262c00a2006-03-30 10:53:17 +0000859- Fixed bug #1459029 - unicode reprs were double-escaped.
860
Hye-Shik Changd478f342006-03-23 12:32:36 +0000861- Patch #1396919: The system scope threads are reenabled on FreeBSD
862 5.4 and later versions.
863
Neal Norwitze98ccf62006-03-23 05:39:47 +0000864- Bug #1115379: Compiling a Unicode string with an encoding declaration
865 now gives a SyntaxError.
866
Georg Brandlabd1ff82006-03-18 07:59:59 +0000867- Previously, Python code had no easy way to access the contents of a
868 cell object. Now, a ``cell_contents`` attribute has been added
869 (closes patch #1170323).
870
Tim Peterscf79aac2006-03-16 01:14:46 +0000871- Patch #1123430: Python's small-object allocator now returns an arena to
872 the system ``free()`` when all memory within an arena becomes unused
873 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
874 freed. Some applications will see a drop in virtual memory size now,
875 especially long-running applications that, from time to time, temporarily
876 use a large number of small objects. Note that when Python returns an
877 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000878 platform C library will in turn return that memory to the operating system.
879 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000880 appears to be effective at least on Microsoft C and gcc-based systems.
881 Thanks to Evan Jones for hard work and patience.
882
Georg Brandl533ff6f2006-03-08 18:09:27 +0000883- Patch #1434038: property() now uses the getter's docstring if there is
884 no "doc" argument given. This makes it possible to legitimately use
885 property() as a decorator to produce a read-only property.
886
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000887- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
888 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
889 of requiring an int or long in slicing and a few other contexts, enabling
890 other objects (e.g. Numeric Python's integers) to be used as slice indices.
891
Neal Norwitz995acdf2006-03-07 05:01:00 +0000892- Fixed various bugs reported by Coverity's Prevent tool.
893
Brett Cannonbf364092006-03-01 04:25:17 +0000894- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
895 new exception base class, BaseException, which has a new message attribute.
896 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
897 Raising a string exception now raises a DeprecationWarning.
898
Thomas Woutersfb609f42006-02-28 16:37:25 +0000899- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
900 explicitly relative, using 'from .module import name' to mean 'from the same
901 package as this module is in. Imports without dots still default to the
902 old relative-then-absolute, unless 'from __future__ import
903 absolute_import' is used.
904
Brett Cannona7446e32006-02-27 23:39:10 +0000905- Properly check if 'warnings' raises an exception (usually when a filter set
906 to "error" is triggered) when raising a warning for raising string
907 exceptions.
908
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000909- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000910 The name was removed from Include/code.h.
911
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000912- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000913
Guido van Rossum1968ad32006-02-25 22:38:04 +0000914- Patch 1433928:
915 - The copy module now "copies" function objects (as atomic objects).
916 - dict.__getitem__ now looks for a __missing__ hook before raising
917 KeyError.
918
Tim Peters84ef21c2006-02-28 20:39:06 +0000919- PEP 343: with statement implemented. Needs ``from __future__ import
920 with_statement``. Use of 'with' as a variable will generate a warning.
921 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000922 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000923 The following objects have __context__ methods:
924 - The built-in file type.
925 - The thread.LockType type.
926 - The following types defined by the threading module:
927 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
928 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000929
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000930- Fix the encodings package codec search function to only search
931 inside its own package. Fixes problem reported in patch #1433198.
932
933 Note: Codec packages should implement and register their own
934 codec search function. PEP 100 has the details.
935
Tim Peters9ea89d22006-06-04 03:26:02 +0000936- PEP 353: Using ``Py_ssize_t`` as the index type.
937
938- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
939 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
940 now allow Python to make use of memory blocks exceeding 2**32 bytes for
941 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
942 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000943
Neal Norwitzfc76d632006-01-10 06:03:13 +0000944- Patch #1400181, fix unicode string formatting to not use the locale.
945 This is how string objects work. u'%f' could use , instead of .
946 for the decimal point. Now both strings and unicode always use periods.
947
Neal Norwitz671b9e32006-01-09 07:07:12 +0000948- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
949 configure would break checking curses.h.
950
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000951- Bug #959576: The pwd module is now builtin. This allows Python to be
952 built on UNIX platforms without $HOME set.
953
Neal Norwitzc10978f2005-12-19 06:07:16 +0000954- Bug #1072182, fix some potential problems if characters are signed.
955
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000956- Bug #889500, fix line number on SyntaxWarning for global declarations.
957
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000958- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
959
Neal Norwitze7214a12005-12-18 05:03:17 +0000960- Support for converting hex strings to floats no longer works.
961 This was not portable. float('0x3') now raises a ValueError.
962
Barry Warsaw2a38a862005-12-18 01:27:35 +0000963- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000964 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000965 is now displayed in interactive prompt banner.
966
Georg Brandlfa166682005-12-17 21:45:17 +0000967- Implementation of PEP 341 - Unification of try/except and try/finally.
968 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000969 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000970
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000971- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
972 now encodes backslash correctly.
973
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000974- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
975
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000976- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000977 and long longs.
978
Neal Norwitz67715f02005-11-09 06:59:35 +0000979- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000980 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000981 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000982
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000983- Replaced most Unicode charmap codecs with new ones using the
984 new Unicode translate string feature in the builtin charmap
985 codec; the codecs were created from the mapping tables available
986 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
987 encodings now include a mapping for the Apple logo)
988
Tim Peterse3547fd2005-12-16 23:13:57 +0000989- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000990
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000991- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000992
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000993- A new AST parser implementation was completed. The abstract
994 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000995 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000996
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000997- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000998 The following code now raises a SyntaxError: foo(a = i for i in range(10))
999
Neal Norwitz708e51a2005-10-03 04:48:15 +00001000- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1001
Neal Norwitz11bd1192005-10-03 00:54:56 +00001002- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1003 Provide a warning when a directory is passed on the command line.
1004
Neal Norwitz40d37812005-10-02 01:48:49 +00001005- Fix segfault with invalid coding.
1006
1007- SF bug #772896: unknown encoding results in MemoryError.
1008
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001009- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001010 supported a __len__() method which evaluated to False when the iterator
1011 was empty.
1012
Guido van Rossum630db602005-09-20 18:49:54 +00001013- On 64-bit platforms, when __len__() returns a value that cannot be
1014 represented as a C int, raise OverflowError.
1015
Skip Montanarof8948ca2005-09-19 03:54:46 +00001016- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001017 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001018
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001019- SF bug #893549: parsing keyword arguments was broken with a few format
1020 codes.
1021
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001022- Changes donated by Elemental Security to make it work on AIX 5.3
1023 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1024 bug #105470: test_pwd fails on 64bit system (Opteron).
1025
Guido van Rossum539c6622005-09-14 17:49:54 +00001026- Changes donated by Elemental Security to make it work on HP-UX 11 on
1027 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1028
Georg Brandl4550b8d2005-08-26 06:43:52 +00001029- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001030 (fixes bug #1119418).
1031
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001032- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1033
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001034- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1035 exceptions that cause a function to exit.
1036
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001037- The implementation of set() and frozenset() was revised to use its
1038 own internal data structure. Memory consumption is reduced by 1/3
1039 and there are modest speed-ups as well. The API is unchanged.
1040
Tim Petersde7990b2005-07-17 23:45:23 +00001041- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1042
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001043- SF bug #1229429: PyObject_CallMethod failed to decrement some
1044 reference counts in some error exit cases.
1045
Tim Petersecc6e6a2005-07-10 22:30:55 +00001046- SF bug #1185883: Python's small-object memory allocator took over
1047 a block managed by the platform C library whenever a realloc specified
1048 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001049 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001050 portable way to copy data from the C-managed block into Python's
1051 small-object space without risking a memory fault. Python's small-object
1052 realloc now leaves such blocks under the control of the platform C
1053 realloc.
1054
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001055- SF bug #1232517: An overflow error was not detected properly when
1056 attempting to convert a large float to an int in os.utime().
1057
Raymond Hettinger3296e692005-06-29 23:29:56 +00001058- SF bug #1224347: hex longs now print with lowercase letters just
1059 like their int counterparts.
1060
Michael W. Hudson188d4362005-06-20 16:52:57 +00001061- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1062 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1063 interpreter states; back out that fix and do a better job (see
1064 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1065 for a longer write-up of the problem).
1066
Michael W. Hudsondf888462005-06-03 14:41:55 +00001067- SF patch #1180995: marshal now uses a binary format by default when
1068 serializing floats.
1069
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001070- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1071 the routines that promise to produce IEEE 754 binary representations
1072 of floats now simply copy bytes around.
1073
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001074- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1075 278.
1076
Brett Cannonc3647ac2005-04-26 03:45:26 +00001077- patch #1109424: int, long, float, complex, and unicode now check for the
1078 proper magic slot for type conversions when subclassed. Previously the
1079 magic slot was ignored during conversion. Semantics now match the way
1080 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001081 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001082 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001083 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001084
Barry Warsawc8d907c2005-04-19 23:43:40 +00001085- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1086 NULL, now raise an AttributeError when attempting to set or delete the
1087 attribute. Previously a TypeError was raised, but this was inconsistent
1088 with the equivalent pure-Python implementation.
1089
Michael W. Hudson774479c2005-04-18 08:46:17 +00001090- It is now safe to call PyGILState_Release() before
1091 PyEval_InitThreads() (note that if there is reason to believe there
1092 are multiple threads around you still must call PyEval_InitThreads()
1093 before using the Python API; this fix is for extension modules that
1094 have no way of knowing if Python is multi-threaded yet).
1095
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001096- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1097 disabled caused a crash.
1098
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001099- Bug #1165306: instancemethod_new allowed the creation of a method
1100 with im_class == im_self == NULL, which caused a crash when called.
1101
Tim Petersecc6e6a2005-07-10 22:30:55 +00001102- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001103 fixes the crash seen in bug #1165761
1104
Raymond Hettinger96229b12005-03-11 06:49:40 +00001105- Added two new builtins, any() and all().
1106
Brett Cannon409d8f22005-03-05 06:47:57 +00001107- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001108 (e.g., ``class C(): pass`` is no longer a syntax error).
1109 Patch #1176012 added support to the 'parser' module and 'compiler' package
1110 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001111
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001112- Patch #1115086: Support PY_LONGLONG in structmember.
1113
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001114- Bug #1155938: new style classes did not check that __init__() was
1115 returning None.
1116
Tim Petersecc6e6a2005-07-10 22:30:55 +00001117- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001118 ('\') with a specific error message.
1119
Martin v. Löwisff232d72005-03-03 09:24:38 +00001120- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1121
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001122- Bug #1124295: the __name__ attribute of file objects was
1123 inadvertently made inaccessible in restricted mode.
1124
Tim Petersecc6e6a2005-07-10 22:30:55 +00001125- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001126 an ferror() call.
1127
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001128- min() and max() now support key= arguments with the same meaning as in
1129 list.sort().
1130
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001131- The peephole optimizer now performs simple constant folding in expressions:
1132 (2+3) --> (5).
1133
Raymond Hettingera422c342005-01-11 03:03:27 +00001134- set and frozenset objects can now be marshalled. SF #1098985.
1135
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001136- Bug #1077106: Poor argument checking could cause memory corruption
1137 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001138
Jeremy Hyltonab630502005-02-04 18:44:06 +00001139- The parser did not complain about future statements in illegal
1140 positions. It once again reports a syntax error if a future
1141 statement occurs after anything other than a doc string.
1142
Neil Schemenauercf52c072005-08-12 17:34:58 +00001143- Change the %s format specifier for str objects so that it returns a
1144 unicode instance if the argument is not an instance of basestring and
1145 calling __str__ on the argument returns a unicode instance.
1146
Tim Petersf4e69282006-02-27 17:15:31 +00001147- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1148 current thread state when the auto-GIL-state machinery knows about
1149 it (since the thread state is being deleted, continuing to remember it
1150 can't help, but can hurt if another thread happens to get created with
1151 the same thread id).
1152
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001153Extension Modules
1154-----------------
1155
Georg Brandl43f08a82006-03-31 18:01:16 +00001156- Patch #1380952: fix SSL objects timing out on consecutive read()s
1157
Neal Norwitz05a45592006-03-20 06:30:08 +00001158- Patch #1309579: wait3 and wait4 were added to the posix module.
1159
Anthony Baxterfa869072006-03-20 05:21:58 +00001160- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1161 In addition, the existing ulaw code was updated.
1162
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001163- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001164 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001165
Neal Norwitz10be10c2006-03-16 06:50:13 +00001166- Everything under lib-old was removed. This includes the following modules:
1167 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001168 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001169 util, whatsound, whrandom, zmod
1170
1171- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1172
1173- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001174 is deprecated. The undocumented re.engine variable no longer exists.
1175
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001176- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1177 SS2 (single-shift 2) escape sequences correctly.
1178
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001179- The unicodedata module was updated to the 4.1 version of the Unicode
1180 database. The 3.2 version is still available as unicodedata.db_3_2_0
1181 for applications that require this specific version (such as IDNA).
1182
Neal Norwitzb62c4332006-03-04 18:35:47 +00001183- The timing module is no longer built by default. It was deprecated
1184 in PEP 4 in Python 2.0 or earlier.
1185
Guido van Rossum1968ad32006-02-25 22:38:04 +00001186- Patch 1433928: Added a new type, defaultdict, to the collections module.
1187 This uses the new __missing__ hook behavior added to dict (see above).
1188
Georg Brandldbd83392006-02-20 09:42:33 +00001189- Bug #854823: socketmodule now builds on Sun platforms even when

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001343- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1344 been renamed to have only a single underscore prefix. This was done to
1345 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001346
Nick Coghlan43832302006-04-23 17:04:07 +00001347- PEP 338: new module runpy defines a run_module function to support
1348 executing modules which provide access to source code or a code object
1349 via the PEP 302 import mechanisms.
1350
Anthony Baxter93f5b932006-04-03 08:05:07 +00001351- The email module's parsedate_tz function now sets the daylight savings

1359 in attribute values.
1360
Anthony Baxterc51ee692006-04-01 00:57:31 +00001361- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001362 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001363 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001364 module will not be built.
1365
Tim Petersc17976e2006-04-01 00:26:53 +00001366- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1367 aren't officially supported here, and trying to use them will probably
1368 raise an exception some day. But dicts have been allowed, and "mostly
1369 worked", so support for them won't go away without warning.
1370
Georg Brandl338ef7d2006-03-31 18:42:16 +00001371- Bug #1445068: getpass.getpass() can now be given an explicit stream
1372 argument to specify where to write the prompt.
1373

1389
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001390- email 4.0 package now integrated. This is largely the same as the email 3.0
1391 package that was included in Python 2.3, except that PEP 8 module names are
1392 now used (e.g. mail.message instead of email.Message). The MIME classes
1393 have been moved to a subpackage (e.g. email.mime.text instead of
1394 email.MIMEText). The old names are still supported for now. Several
1395 deprecated Message methods have been removed and lots of bugs have been
1396 fixed. More details can be found in the email package documentation.
1397
Walter Dörwald40108c92006-03-27 08:15:44 +00001398- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1399 (a subclass of tuple) that provides incremental decoders and encoders
1400 (a way to use stateful codecs without the stream API). Python functions
1401 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1402 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1403 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001405- Patch #1359365: Calling next() on a closed StringIO.String object raises
1406 a ValueError instead of a StopIteration now (like file and cString.String do).
1407 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1408 called before (like file and StringIO.StringIO do).

1476
Neal Norwitz338e7862005-12-23 21:27:46 +00001477- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1478 LoadError as documented, instead of IOError. For compatibility,
1479 LoadError subclasses IOError.
1480
Brett Cannon3cbd0382005-12-16 22:49:23 +00001481- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001482 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1483 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1484 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1485 Ronald L. Rivest offered this advice for Python:
1486
1487 "The consensus of researchers in this area (at least as
1488 expressed at the NIST Hash Function Workshop 10/31/05),
1489 is that SHA-256 is a good choice for the time being, but
1490 that research should continue, and other alternatives may
1491 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001492
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001493- Added a subset of Fredrik Lundh's ElementTree package. Available

1546 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001547 correct line numbers for decoding errors in source code.

1570 to W3C name (404 -> 'Not Found'). RFE #1216944.
1571
Georg Brandl9e43acf2005-07-04 17:16:07 +00001572- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1573 as this can cause problems with apps closing all file descriptors.

1586 Bug #1224621.
1587
Raymond Hettinger68c04532005-06-10 11:05:19 +00001588- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001589 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001590 the generate_tokens() function now accepts a callable argument that
1591 terminates by raising StopIteration.
1592
Georg Brandl9166e1a2005-06-04 09:20:03 +00001593- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1607 them to PyPI.
1608
Raymond Hettinger267b8682005-03-27 10:47:39 +00001609- decimal operator and comparison methods now return NotImplemented
1610 instead of raising a TypeError when interacting with other types. This
1611 allows other classes to implement __radd__ style methods and have them
1612 work as expected.
1613
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001614- Bug #1163325: Decimal infinities failed to hash. Attempting to
1615 hash a NaN raised an InvalidOperation instead of a TypeError.
1616
Tim Petersecc6e6a2005-07-10 22:30:55 +00001617- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1651
Guido van Rossumd0641422005-02-03 15:01:24 +00001652- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1653 disables recursive traversal through instance attributes, which can
1654 be exploited in various ways.
1655
Tim Peterse3547fd2005-12-16 23:13:57 +00001656- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001657 flags on the HTTP listening socket.
1658

1660 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1661
Fred Drakefbdeaad2006-07-29 16:56:15 +00001662- Patches #893642, #1039083: add allow_none, encoding arguments to
1663 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001664

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001667- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1668
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001669- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1670
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001671- Enhancements to the csv module:
1672
1673 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001674 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001675 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001676 + Dialect parameter parsing has been re-implemented to improve error
1677 reporting.
1678 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1679 dictates.
1680 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001681 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001682 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001683 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1684 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001685 + reader now allows \r characters to be quoted (previously it only allowed
1686 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001687 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001688 + Dialect classes passed to the module are no longer instantiated by
1689 the module before being parsed (the former validation scheme required
1690 this, but the mechanism was unreliable).
1691 + The dialect registry now contains instances of the internal
1692 C-coded dialect type, rather than references to python objects.
1693 + the internal c-coded dialect type is now immutable.
1694 + register_dialect now accepts the same keyword dialect specifications
1695 as the reader and writer, allowing the user to register dialects
1696 without first creating a dialect class.
1697 + a configurable limit to the size of parsed fields has been added -
1698 previously, an unmatched quote character could result in the entire
1699 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001700 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001701 the parser field size limit (returning the former limit). The initial
1702 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001703 + A line_num attribute has been added to the reader object, which tracks
1704 the number of lines read from the source iterator. This is not
1705 the same as the number of records returned, as records can span
1706 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001707 + reader and writer objects were not being registered with the cyclic-GC.
1708 This has been fixed.
1709
Brett Cannone6539c42005-01-08 02:43:53 +00001710- _DummyThread objects in the threading module now delete self.__block that is
1711 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1712 lock primitives tend to be limited in number and thus should not be wasted on
1713 a _DummyThread object. Fixes bug #1089632.
1714
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001715- The imghdr module now detects Exif files.
1716
Raymond Hettinger6065d322004-12-20 23:51:53 +00001717- StringIO.truncate() now correctly adjusts the size attribute.
1718 (Bug #951915).
1719
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001720- locale.py now uses an updated locale alias table (built using
1721 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1722 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001723 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001724
Raymond Hettinger3557f422004-12-07 12:02:02 +00001725- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1726
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001727- the pickle module no longer accepts the deprecated None option in the
1728 args tuple returned by __reduce__().
1729
Brett Cannon84667c02004-12-07 03:25:18 +00001730- optparse now optionally imports gettext. This allows its use in setup.py.
1731
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001732- the pickle module no longer uses the deprecated bin parameter.
1733
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001734- the shelve module no longer uses the deprecated binary parameter.
1735

1737
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001738- the filecmp module no longer uses the deprecated use_statcache argument.
1739
Raymond Hettinger664347b2004-12-04 21:21:53 +00001740- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1741 extended or overridden by subclasses. Formerly, the subclassed method would
1742 be ignored by the rest of the module. (Bug #1078905).
1743
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001744- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001745 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001746
Walter Dörwald36733692004-12-22 12:50:50 +00001747- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1748 once when a size argument is given. This prevents a buffer overflow in the
1749 tokenizer with very long source lines.
1750
Barry Warsaw538561e2006-01-01 21:48:54 +00001751- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1752 immediately after creating the object, without any intervening
1753 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001754
Skip Montanaro05885812005-01-16 20:48:27 +00001755- The reconvert.quote function can now emit triple-quoted strings. The
1756 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001757
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001758- ``UserString.MutableString`` now supports negative indices in
1759 ``__setitem__`` and ``__delitem__``
1760
Greg Ward40407942005-03-05 02:53:17 +00001761- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1762 correctly.
1763
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001764- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1765 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1766 character even if the user has passed a size parameter to get a proper
1767 line ending. Remove the special handling of a "\r\n" that has been split
1768 between two lines.
1769
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001770- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1771 about illegal code points. The codec now supports PEP 293 style error
1772 handlers.
1773
Walter Dörwald78a78b02005-09-01 12:04:29 +00001774- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001775 from the input stream, so that the output is a byte string in the correct
1776 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001777
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001778- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1779 considering it exactly like a '*'.
1780
Walter Dörwald007f8df2005-10-09 19:42:27 +00001781- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1782 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001783
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001784- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1785
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001786- Patch #1413711: Certain patterns of differences were making difflib
1787 touch the recursion limit.
1788
Walter Dörwald58917a62006-03-31 15:26:22 +00001789- Bug #947906: An object oriented interface has been added to the calendar
1790 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001791 called as a script (e.g. via ``python -mcalendar``). Localized month and
1792 weekday names can be ouput (even if an exotic encoding is used) using
1793 special classes that use unicode.

1797
Neal Norwitz602d3392006-03-31 08:21:40 +00001798- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1799 by using -mieee gcc option.
1800

1802
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001803- Build support for Win64-AMD64 was added.
1804
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001805- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1806
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001807- Patch #881820: look for openpty and forkpty also in libbsd.
1808
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001809- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1810 The zlib module is now builtin on Windows.
1811
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001812- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1813
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001814- Bug #1189330: configure did not correctly determine the necessary
1815 value of LINKCC if python was built with GCC 4.0.
1816
Trent Mick8321b422005-07-26 02:29:21 +00001817- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1818 vulnerability in zlib 1.2.1 and 1.2.2.
1819
Brett Cannon08cd5982005-04-24 22:26:38 +00001820- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1821 flags that change binary compatibility. Changes were also made to
1822 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001823 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001824
Bob Ippolitoed233462005-03-29 13:47:59 +00001825- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1826 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1827 no longer exists). This configure patch makes things right.
1828
Martin v. Löwise2713be2005-03-08 15:03:08 +00001829- Bug #1158607: Build with --disable-unicode again.
1830
Brett Cannon46d96232005-02-16 00:07:19 +00001831- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1832 defined. Discovered as a result of not being able to build on OS X.
1833
Brett Cannon516592f2004-12-07 00:42:59 +00001834- setup.py now uses the directories specified in LDFLAGS using the -L option
1835 and in CPPFLAGS using the -I option for adding library and include
1836 directories, respectively, for compiling extension modules against. This has
1837 led to the core being compiled using the values in CPPFLAGS. It also removes
1838 the need for the special-casing of both DarwinPorts and Fink for darwin since
1839 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1840 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1841 Fink, ``-I/opt/local/include`` for DarwinPorts).
1842
Brett Cannon43802422005-02-10 20:48:03 +00001843- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1844 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1845 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1846 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001848C API
1849-----
1850
Tim Petersc9d78aa2006-03-26 23:27:58 +00001851- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1852 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1853 is obtained via the ``PyObject_`` family, it must be released via the
1854 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1855 always been officially true, but when Python's small-object allocator was
1856 introduced, an attempt was made to cater to a few extension modules
1857 discovered at the time that obtained memory via ``PyObject_New`` but
1858 released it via ``PyMem_DEL``. It's years later, and if such code still
1859 exists it will fail now (probably with segfaults, but calling wrong
1860 low-level memory management functions can yield many symptoms).
1861
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001862- Added a C API for set and frozenset objects.
1863
Raymond Hettinger66517482004-12-03 11:45:13 +00001864- Removed PyRange_New().
1865
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001866- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1867 mapping argument now. This string is used as a mapping table. Byte values
1868 greater than the length of the string and 0xFFFE are treated as undefined
1869 mappings.
