Georg Brandl9dceedb2006-07-12 15:31:17 +000015- Patch #1521179: Python now accepts the standard options ``--help`` and
16 ``--version`` as well as ``/?`` on Windows.
17
Neal Norwitza1f10902006-07-12 07:28:29 +000018- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
19 again. Fixing this problem required changing the .pyc magic number.
20 This means that .pyc files generated before 2.5c1 will be regenerated.

Thomas Hellerce049a02006-07-14 17:51:14 +000028- Patch #1521817: Index range checking on ctypes arrays containing
29 exactly one element enabled again. This allows iterating over these
30 arrays, without the need to check the array size before.
31
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000032- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000033 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000034 /dev/null in certain cases; this is now fixed.
35
Thomas Heller47d7a062006-07-12 08:43:47 +000036- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
37 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000038
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000039- Because of a misspelled preprocessor symbol, ctypes was always
40 compiled without thread support; this is now fixed.

48-----------------
49
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000050- Bug #1441486: The literal representation of -(sys.maxint - 1)
51 again evaluates to a int object, not a long.
52
Neil Schemenauer0e07b602006-07-09 16:16:34 +000053- Bug #1501934: The scope of global variables that are locally assigned
54 using augmented assignment is now correctly determined.
55
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000056- Bug #927248: Recursive method-wrapper objects can now safely
57 be released.
58
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000059- Bug #1417699: Reject locale-specific decimal point in float()
60 and atof().
61
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000062- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
63 omit a default "error" argument for NULL pointer. This allows
64 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000065
Neal Norwitzfb48afa2006-07-08 05:31:37 +000066- Bug #1519018: 'as' is now validated properly in import statements.
67
Neal Norwitz28746ab2006-07-09 22:14:42 +000068- On 64 bit systems, int literals that use less than 64 bits are
69 now ints rather than longs.
70
Neal Norwitzed657552006-07-10 00:04:44 +000071- Bug #1512814, Fix incorrect lineno's when code at module scope
72 started after line 256.
73
Tim Peters32a83612006-07-10 21:08:24 +000074- New function ``sys._current_frames()`` returns a dict mapping thread
75 id to topmost thread stack frame. This is for expert use, and is
76 especially useful for debugging application deadlocks. The functionality
77 was previously available in Fazal Majid's ``threadframe`` extension
78 module, but it wasn't possible to do this in a wholly threadsafe way from
79 an extension.

85
Tim Peters32a83612006-07-10 21:08:24 +000086- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +000087 environment variable to be set in order to the SDK environment
88 for finding the compiler, include files, etc.
89
Martin v. Löwis388a8c22006-07-06 19:28:03 +000090- Bug #1515998: Properly generate logical ids for files in bdist_msi.
91
Nick Coghlan2d792252006-07-06 13:47:18 +000092- warnings.py now ignores ImportWarning by default
93
Thomas Woutersadd19112006-07-05 11:03:49 +000094- string.Template() now correctly handles tuple-values. Previously,
95 multi-value tuples would raise an exception and single-value tuples would
96 be treated as the value they contain, instead.
97
Martin v. Löwisede77f52006-07-03 13:01:35 +000098- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
99 even if some data are received.
100
Martin v. Löwis45482392006-07-03 12:28:58 +0000101- Bug #1267547: Put proper recursive setup.py call into the
102 spec file generated by bdist_rpm.
103
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000104- Bug #1514693: Update turtle's heading when switching between
105 degrees and radians.
106
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000107- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000108 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000109
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000110- Bug #1514703: Only setup canvas window in turtle when the canvas
111 is created.
112
Martin v. Löwis7596e832006-07-01 15:33:37 +0000113- Bug #1513223: .close() of a _socketobj now releases the underlying
114 socket again, which then gets closed as it becomes unreferenced.
115
Fred Drake10497c82006-06-29 02:57:48 +0000116- Bug #1504333: Make sgmllib support angle brackets in quoted
117 attribute values.
118
119- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
120 sgmllib ('[' and ']' were not accepted).
121
Georg Brandl1be63af2006-06-28 20:23:25 +0000122- Fix a bug in the turtle module's end_fill function.
123
Brett Cannon53ab5b72006-06-22 16:49:14 +0000124- Bug #1510580: The 'warnings' module improperly required that a Warning
125 category be either a types.ClassType and a subclass of Warning. The proper
126 check is just that it is a subclass with Warning as the documentation states.
127
Georg Brandlad29e632006-06-21 17:45:17 +0000128- The compiler module now correctly compiles the new try-except-finally
129 statement (bug #1509132).
130
Neal Norwitz60373cd2006-06-22 06:30:50 +0000131- The wsgiref package is now installed properly on Unix.
132
Vinay Sajip28e57612006-07-01 10:45:20 +0000133- A bug was fixed in logging.config.fileConfig() which caused a crash on
134 shutdown when fileConfig() was called multiple times.
135
Gerhard Häring762fbd32006-07-02 17:48:30 +0000136- The sqlite3 module did cut off data from the SQLite database at the first
137 null character before sending it to a custom converter. This has been fixed
138 now.
139
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000140Extension Modules
141-----------------
142
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000143- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
144 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
145 The patch makes sockets use poll() internally where available.
146
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000147- Assigning None to pointer type fields in ctypes structures possible
148 overwrote the wrong fields, this is fixed now.
149
150- Fixed a segfault in _ctypes when ctypes.wintypes were imported
151 on non-Windows platforms.
152
153- Bug #1518190: The ctypes.c_void_p constructor now accepts any
154 integer or long, without range checking.
155
156- Patch #1517790: It is now possible to use custom objects in the ctypes
157 foreign function argtypes sequence as long as they provide a from_param
158 method, no longer is it required that the object is a ctypes type.
159
160- The '_ctypes' extension module now works when Python is configured
161 with the --without-threads option.
162
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000163- Bug #1513646: os.access on Windows now correctly determines write
164 access, again.
165
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000166- Bug #1512695: cPickle.loads could crash if it was interrupted with
167 a KeyboardInterrupt.
168
Neal Norwitza12aa882006-07-06 06:45:08 +0000169- Bug #1296433: parsing XML with a non-default encoding and
170 a CharacterDataHandler could crash the interpreter in pyexpat.
171
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000172- Patch #1516912: improve Modules support for OpenVMS.
173
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000174Build
175-----
176
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000177- Automate Windows build process for the Win64 SSL module.
178
Tim Peters32a83612006-07-10 21:08:24 +0000179- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000180 Previously, the slight difference could cause compilation errors of the
181 'zlib' module on systems with more than one version of zlib.
182
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000183- The MSI compileall step was fixed to also support a TARGETDIR
184 with spaces in it.
185
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000186- Bug #1517388: sqlite3.dll is now installed on Windows independent
187 of Tcl/Tk.
188
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000189- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000190 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000191
Neal Norwitzb15ac312006-06-29 04:10:08 +0000192Tests

202 documentation for the warnings module.
203
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000204- Patch #1509163: MS Toolkit Compiler no longer available.

Georg Brandlad29e632006-06-21 17:45:17 +0000209================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000210

Anthony Baxter51bcb682006-04-05 14:51:42 +0000212
213Core and builtins
214-----------------
215
Georg Brandla56b9152006-06-19 06:35:54 +0000216- Patch #1507676: Error messages returned by invalid abstract object operations
217 (such as iterating over an integer) have been improved and now include the
218 type of the offending object to help with debugging.
219
Brett Cannonea3912b2006-06-13 21:46:41 +0000220- Bug #992017: A classic class that defined a __coerce__() method that returned
221 its arguments swapped would infinitely recurse and segfault the interpreter.
222
Neal Norwitz909eb122006-06-12 02:13:21 +0000223- Fix the socket tests so they can be run concurrently.
224
Neal Norwitzb9845e72006-06-12 02:11:18 +0000225- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000226 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000227
Brett Cannon22565aa2006-06-09 22:31:23 +0000228- Bug #532646: object.__call__() will continue looking for the __call__
229 attribute on objects until one without one is found. This leads to recursion
230 when you take a class and set its __call__ attribute to an instance of the
231 class. Originally fixed for classic classes, but this fix is for new-style.
232 Removes the infinite_rec_3 crasher.
233
Georg Brandl24250812006-06-09 18:45:48 +0000234- The string and unicode methods startswith() and endswith() now accept
235 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
236
Brett Cannonde3b0522006-06-08 17:00:45 +0000237- Buffer objects, at the C level, never used the char buffer
238 implementation even when the char buffer for the wrapped object was
239 explicitly requested (originally returned the read or write buffer).
240 Now a TypeError is raised if the char buffer is not present but is
241 requested.
242
Georg Brandlddbaa662006-06-04 21:56:52 +0000243- Patch #1346214: Statements like "if 0: suite" are now again optimized
244 away like they were in Python 2.4.
245
Georg Brandlb7c8f542006-05-27 12:30:25 +0000246- Builtin exceptions are now full-blown new-style classes instead of
247 instances pretending to be classes, which speeds up exception handling
248 by about 80% in comparison to 2.5a2.
249
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000250- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
251 Unicode 4.1.
252
Georg Brandlf4ef1162006-05-26 18:03:31 +0000253- Patch #921466: sys.path_importer_cache is now used to cache valid and
254 invalid file paths for the built-in import machinery which leads to
255 fewer open calls on startup.
256
Tim Peters696cf432006-05-24 21:10:40 +0000257- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
258 of-2 bases. The largest speedup is for inputs with about 1000 decimal
259 digits. Conversion from non-power-of-2 bases remains quadratic-time in
260 the number of input digits (it was and remains linear-time for bases
261 2, 4, 8, 16 and 32).
262
Tim Petersb713ec22006-05-23 18:45:30 +0000263- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
264 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
265 an integer close to ``sys.maxint``. This was repaired by patch
266 #1335972, which also gives a nice speedup.
267
Richard Jonescebbefc2006-05-23 18:28:17 +0000268- Patch #1337051: reduced size of frame objects.
269
270- PyErr_NewException now accepts a tuple of base classes as its
271 "base" parameter.
272
Richard Jones7c88dcc2006-05-23 10:37:38 +0000273- Patch #876206: function call speedup by retaining allocated frame
274 objects.
275
Georg Brandl7b90e162006-05-18 07:01:27 +0000276- Bug #1462152: file() now checks more thoroughly for invalid mode
277 strings and removes a possible "U" before passing the mode to the
278 C library function.
279
Neal Norwitz1004a532006-05-15 07:17:23 +0000280- Patch #1488312, Fix memory alignment problem on SPARC in unicode
281
Neal Norwitz373f0a72006-05-15 07:04:36 +0000282- Bug #1487966: Fix SystemError with conditional expression in assignment
283
Martin v. Löwis879768d2006-05-11 13:28:43 +0000284- WindowsError now has two error code attributes: errno, which carries
285 the error values from errno.h, and winerror, which carries the error
286 values from winerror.h. Previous versions put the winerror.h values
287 (from GetLastError()) into the errno attribute.
288
Martin v. Löwis77736712006-05-04 05:51:03 +0000289- Patch #1475845: Raise IndentationError for unexpected indent.
290
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000291- Patch #1479181: split open() and file() from being aliases for each other.
292
Tim Peters44bd9862006-06-01 13:49:23 +0000293- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
294 methods were always silently ignored by dictionaries when comparing keys.
295 They are now passed through (except when using the C API function
296 ``PyDict_GetItem()``, whose semantics did not change).
297
298- Bug #1456209: In some obscure cases it was possible for a class with a
299 custom ``__eq__()`` method to confuse dict internals when class instances
300 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
301 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +0000306- Bug #1295808: expat symbols should be namespaced in pyexpat
307
308- Patch #1462338: Upgrade pyexpat to expat 2.0.0
309
Brett Cannon6ee7d012006-06-08 16:23:04 +0000310- Change binascii.hexlify to accept a read-only buffer instead of only a char
311 buffer and actually follow its documentation.
312
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000313- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
314
Nick Coghlanc649ec52006-05-29 12:43:05 +0000315- Patch #1478788 (modified version): The functional extension module has
316 been renamed to _functools and a functools Python wrapper module added.
317 This provides a home for additional function related utilities that are

Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000320- Patch #1493701: performance enhancements for struct module.
321
Georg Brandl378d5922006-05-17 14:26:50 +0000322- Patch #1490224: time.altzone is now set correctly on Cygwin.
323
Georg Brandl8d3342b2006-05-16 07:38:27 +0000324- Patch #1435422: zlib's compress and decompress objects now have a
325 copy() method.
326
Andrew MacIntyre92913322006-06-13 15:04:24 +0000327- Patch #1454481: thread stack size is now tunable at runtime for thread
328 enabled builds on Windows and systems with Posix threads support.
329
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000330- On Win32, os.listdir now supports arbitrarily-long Unicode path names
331 (up to the system limit of 32K characters).
332
333- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
334 As a result, these functions now raise WindowsError instead of OSError.
335
Tim Peters7a822da2006-05-25 21:50:17 +0000336- ``time.clock()`` on Win64 should use the high-performance Windows
337 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
338 Windows platforms).
339
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000340- Calling Tk_Init twice is refused if the first call failed as that
341 may deadlock.
342
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000343- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
344 accept it without potentially using an uninitialized pointer.
345
346- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
347 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +0000350- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000351 [pybsddb project SF patch number 1466734]
352
Gregory P. Smith372b5832006-06-05 18:48:21 +0000353- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
354 parameter is supplied. [SF pybsddb bug #1477863]
355
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000356- bsddb: the __len__ method of a DB object has been fixed to return correct
357 results. It could previously incorrectly return 0 in some cases.
358 Fixes SF bug 1493322 (pybsddb bug 1184012).
359
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000360- bsddb: the bsddb.dbtables Modify method now raises the proper error and
361 aborts the db transaction safely when a modifier callback fails.
362 Fixes SF python patch/bug #1408584.
363
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000364- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000365 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000366 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
367 database calls that would previously deadlock. [SF python bug #775414]
368
Vinay Sajip28e57612006-07-01 10:45:20 +0000369- Patch #1446489: add support for the ZIP64 extensions to zipfile.

395
Martin v. Löwisd8251432006-06-14 05:21:04 +0000396- Patch #1455898: The MBCS codec now supports the incremental mode for
397 double-byte encodings.
398
Tim Peters43898b42006-06-14 04:09:25 +0000399- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
400 guarantee that adjacent triples in the return list always describe
401 non-adjacent blocks. Previously, a pair of matching blocks could end
402 up being described by multiple adjacent triples that formed a partition
403 of the matching pair.
404
Greg Ward0e0c9f42006-06-11 16:24:11 +0000405- Bug #1498146: fix optparse to handle Unicode strings in option help,
406 description, and epilog.
407

411 clarify docs.
412
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000413- The wsgiref package has been added to the standard library.
414
Nick Coghlan676725d2006-06-08 13:54:49 +0000415- The functions update_wrapper() and wraps() have been added to the functools
416 module. These make it easier to copy relevant metadata from the original
417 function when writing wrapper functions.
418
Tim Petersd6a9eef2006-06-05 01:48:21 +0000419- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
420 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000421
Martin v. Löwis3f767792006-06-04 19:36:28 +0000422- Patch #1359618: Speed up charmap encoder by using a trie structure
423 for lookup.
424
Tim Petersd609b1a2006-06-02 23:22:51 +0000425- The functions in the ``pprint`` module now sort dictionaries by key
426 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
427 if and only if its display required more than one line, although that
428 wasn't documented. The new behavior increases predictability; e.g.,
429 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
430
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000431- Patch #1497027: try HTTP digest auth before basic auth in urllib2

Bob Ippolito7298f272006-05-23 18:43:47 +0000439- Patch #1281707: speed up gzip.readline.
440
Georg Brandlb89316f2006-05-17 15:51:16 +0000441- Patch #1180296: Two new functions were added to the locale module:
442 format_string() to get the effect of "format % items" but locale-aware,
443 and currency() to format a monetary number with currency sign.
444
Georg Brandle3a25832006-05-17 14:56:04 +0000445- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
446 and several features added, such as speed and geometry control.

449 tarfiles.
450
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000451- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
452 stdout arguments, making it possible to redirect input and output
453 for remote debugging.
454
455- Patch #1484695: Update the tarfile module to version 0.8. This fixes
456 a couple of issues, notably handling of long file names using the
457 GNU LONGNAME extension.
458
459- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
460 new flag when ``name`` is already the name of an option flag.
461
462- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
463 package.

502=================================
503
504*Release date: 27-APR-2006*
505
506Core and builtins
507-----------------
508
Thomas Heller1b046642006-04-18 18:51:06 +0000509- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
510 by converting these apis from macros into exported functions again:
511
512 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
513 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
514 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
515 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
516 PyRun_String Py_CompileString
517
Martin v. Löwis45294a92006-04-18 06:24:08 +0000518- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
519
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000520- All uses of PyStructSequence_InitType have been changed to initialize
521 the type objects only once, even if the interpreter is initialized
522 multiple times.
523
Neal Norwitz61546162006-04-14 05:20:28 +0000524- Bug #1454485, array.array('u') could crash the interpreter. This was
525 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
526 to unicode when it didn't make sense. 'u#' now requires a unicode string.
527
528- Py_UNICODE is unsigned. It was always documented as unsigned, but
529 due to a bug had a signed value in previous versions.
530
Tim Peters3a5e8b12006-04-11 01:44:07 +0000531- Patch #837242: ``id()`` of any Python object always gives a positive
532 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
533 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000534 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000535 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000536
Tim Peters3a5e8b12006-04-11 01:44:07 +0000537 def __hash__(self):
538 return id(self) # WRONG
539
540 because a hash result must be a (short) Python int but it was always
541 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000542 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000543 was always usable as a hash value before this patch. That's no longer
544 necessarily so.
545
546- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000547 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000548 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000549 #1454844)
550
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000551- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
552 involving generators that have paused outside of any ``try`` or ``with``
553 blocks. (In 2.5a1, a paused generator that was part of a reference
554 cycle could not be garbage collected, regardless of whether it was
555 paused in a ``try`` or ``with`` block.)

572 a temporary db (file=None) with the 'n' flag to truncate on open.
573
574- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
575 as older versions cause excessive test failures.

581-------
582
Peter Astrand7d1d4362006-07-14 14:04:45 +0000583- Bug #1223937: subprocess.CalledProcessError reports the exit status
584 of the process using the returncode attribute, instead of
585 abusing errno.
586
Tim Peters711bf302006-04-25 03:31:36 +0000587- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
588 a doctest to be skipped (the code is not run, and the expected output
589 or exception is ignored).
590
Nick Coghlanda2268f2006-04-24 04:37:15 +0000591- Fixed contextlib.nested to cope with exceptions being raised and
592 caught inside exit handlers.
593
Greg Wardab05edc2006-04-23 03:47:58 +0000594- Updated optparse module to Optik 1.5.1 (allow numeric constants in
595 hex, octal, or binary; add ``append_const`` action; keep going if
596 gettext cannot be imported; added ``OptionParser.destroy()`` method;
597 added ``epilog`` for better help generation).
598
Tim Peters21fbd572006-04-21 21:18:10 +0000599- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
600 called from a thread spawned as a side effect of importing a module.
601
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000602- The pydoc module now supports documenting packages contained in
603 .zip or .egg files.
604
605- The pkgutil module now has several new utility functions, such
606 as ``walk_packages()`` to support working with packages that are either
607 in the filesystem or zip files.
608
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000609- The mailbox module can now modify and delete messages from
610 mailboxes, in addition to simply reading them. Thanks to Gregory
611 K. Johnson for writing the code, and to the 2005 Google Summer of
612 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000613
Tim Petersc7605f22006-04-17 21:12:33 +0000614- The ``__del__`` method of class ``local`` in module ``_threading_local``
615 returned before accomplishing any of its intended cleanup.
616

Skip Montanaro262fb922006-04-21 02:31:07 +0000637- The pstats.Stats class accepts an optional stream keyword argument to
638 direct output to an alternate file-like object.

641-----
642
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000643- The Makefile now has a reindent target, which runs reindent.py on
644 the library.
645
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000646- Patch #1470875: Building Python with MS Free Compiler
647
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000648- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000649
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000650- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
651 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000652 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000653 CXX from --with-cxx-main, see description in README.
654
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000655- Patch #1429775: Link extension modules with the shared libpython.
656
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000657- Fixed a libffi build problem on MIPS systems.
658
Tim Peters8931ff12006-05-13 23:28:20 +0000659- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
660 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
661 and "%zu" for unsigned integers of type ``size_t``.
662
Anthony Baxter51bcb682006-04-05 14:51:42 +0000663Tests
664-----
665
Nick Coghlanda2268f2006-04-24 04:37:15 +0000666- test_contextlib now checks contextlib.nested can cope with exceptions
667 being raised and caught inside exit handlers.
668
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000669- test_cmd_line now checks operation of the -m and -c command switches
670
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000671- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
672 it separately and by hand. It also wasn't cleaning up its changes to
673 the current Decimal context.
674
Thomas Woutersabd08882006-04-26 15:53:30 +0000675- regrtest.py now has a -M option to run tests that test the new limits of
676 containers, on 64-bit architectures. Running these tests is only sensible
677 on 64-bit machines with more than two gigabytes of memory. The argument
678 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000686Documentation
687-------------
688
Tim Petersb06d28c2006-05-12 01:57:59 +0000689- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
690
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000691- PEP 343: Added Context Types section to the library reference
692 and attempted to bring other PEP 343 related documentation into
693 line with the implementation and/or python-dev discussions.
694
Tim Peters8dc73d22006-04-24 02:03:16 +0000695- Bug #1337990: clarified that ``doctest`` does not support examples
696 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000699What's New in Python 2.5 alpha 1?
700=================================
701
Anthony Baxterebed3f62006-04-03 15:03:44 +0000702*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000703
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000704Core and builtins
705-----------------
706
Nick Coghlan43832302006-04-23 17:04:07 +0000707- PEP 338: -m command line switch now delegates to runpy.run_module
708 allowing it to support modules in packages and zipfiles
709
Martin v. Löwisc661b882006-04-20 04:54:23 +0000710- On Windows, .DLL is not an accepted file name extension for
711 extension modules anymore; extensions are only found if they
712 end in .PYD.
713
Martin v. Löwisea62d252006-04-03 10:56:49 +0000714- Bug #1421664: sys.stderr.encoding is now set to the same value as
715 sys.stdout.encoding.
716
Neal Norwitz92e212f2006-04-03 04:48:37 +0000717- __import__ accepts keyword arguments.
718
Georg Brandlccadf842006-03-31 18:54:53 +0000719- Patch #1460496: round() now accepts keyword arguments.
720
Anthony Baxter262c00a2006-03-30 10:53:17 +0000721- Fixed bug #1459029 - unicode reprs were double-escaped.
722
Hye-Shik Changd478f342006-03-23 12:32:36 +0000723- Patch #1396919: The system scope threads are reenabled on FreeBSD
724 5.4 and later versions.
725
Neal Norwitze98ccf62006-03-23 05:39:47 +0000726- Bug #1115379: Compiling a Unicode string with an encoding declaration
727 now gives a SyntaxError.
728
Georg Brandlabd1ff82006-03-18 07:59:59 +0000729- Previously, Python code had no easy way to access the contents of a
730 cell object. Now, a ``cell_contents`` attribute has been added
731 (closes patch #1170323).
732
Tim Peterscf79aac2006-03-16 01:14:46 +0000733- Patch #1123430: Python's small-object allocator now returns an arena to
734 the system ``free()`` when all memory within an arena becomes unused
735 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
736 freed. Some applications will see a drop in virtual memory size now,
737 especially long-running applications that, from time to time, temporarily
738 use a large number of small objects. Note that when Python returns an
739 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000740 platform C library will in turn return that memory to the operating system.
741 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000742 appears to be effective at least on Microsoft C and gcc-based systems.
743 Thanks to Evan Jones for hard work and patience.
744
Georg Brandl533ff6f2006-03-08 18:09:27 +0000745- Patch #1434038: property() now uses the getter's docstring if there is
746 no "doc" argument given. This makes it possible to legitimately use
747 property() as a decorator to produce a read-only property.
748
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000749- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
750 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
751 of requiring an int or long in slicing and a few other contexts, enabling
752 other objects (e.g. Numeric Python's integers) to be used as slice indices.
753
Neal Norwitz995acdf2006-03-07 05:01:00 +0000754- Fixed various bugs reported by Coverity's Prevent tool.
755
Brett Cannonbf364092006-03-01 04:25:17 +0000756- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
757 new exception base class, BaseException, which has a new message attribute.
758 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
759 Raising a string exception now raises a DeprecationWarning.
760
Thomas Woutersfb609f42006-02-28 16:37:25 +0000761- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
762 explicitly relative, using 'from .module import name' to mean 'from the same
763 package as this module is in. Imports without dots still default to the
764 old relative-then-absolute, unless 'from __future__ import
765 absolute_import' is used.
766
Brett Cannona7446e32006-02-27 23:39:10 +0000767- Properly check if 'warnings' raises an exception (usually when a filter set
768 to "error" is triggered) when raising a warning for raising string
769 exceptions.
770
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000771- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000772 The name was removed from Include/code.h.
773
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000774- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000775
Guido van Rossum1968ad32006-02-25 22:38:04 +0000776- Patch 1433928:
777 - The copy module now "copies" function objects (as atomic objects).
778 - dict.__getitem__ now looks for a __missing__ hook before raising
779 KeyError.
780
Tim Peters84ef21c2006-02-28 20:39:06 +0000781- PEP 343: with statement implemented. Needs ``from __future__ import
782 with_statement``. Use of 'with' as a variable will generate a warning.
783 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000784 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000785 The following objects have __context__ methods:
786 - The built-in file type.
787 - The thread.LockType type.
788 - The following types defined by the threading module:
789 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
790 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000791
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000792- Fix the encodings package codec search function to only search
793 inside its own package. Fixes problem reported in patch #1433198.
794
795 Note: Codec packages should implement and register their own
796 codec search function. PEP 100 has the details.
797
Tim Peters9ea89d22006-06-04 03:26:02 +0000798- PEP 353: Using ``Py_ssize_t`` as the index type.
799
800- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
801 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
802 now allow Python to make use of memory blocks exceeding 2**32 bytes for
803 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
804 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000805
Neal Norwitzfc76d632006-01-10 06:03:13 +0000806- Patch #1400181, fix unicode string formatting to not use the locale.
807 This is how string objects work. u'%f' could use , instead of .
808 for the decimal point. Now both strings and unicode always use periods.
809
Neal Norwitz671b9e32006-01-09 07:07:12 +0000810- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
811 configure would break checking curses.h.
812
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000813- Bug #959576: The pwd module is now builtin. This allows Python to be
814 built on UNIX platforms without $HOME set.
815
Neal Norwitzc10978f2005-12-19 06:07:16 +0000816- Bug #1072182, fix some potential problems if characters are signed.
817
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000818- Bug #889500, fix line number on SyntaxWarning for global declarations.
819
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000820- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
821
Neal Norwitze7214a12005-12-18 05:03:17 +0000822- Support for converting hex strings to floats no longer works.
823 This was not portable. float('0x3') now raises a ValueError.
824
Barry Warsaw2a38a862005-12-18 01:27:35 +0000825- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000826 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000827 is now displayed in interactive prompt banner.
828
Georg Brandlfa166682005-12-17 21:45:17 +0000829- Implementation of PEP 341 - Unification of try/except and try/finally.
830 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000831 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000832
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000833- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
834 now encodes backslash correctly.
835
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000836- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
837
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000838- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000839 and long longs.
840
Neal Norwitz67715f02005-11-09 06:59:35 +0000841- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000842 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000843 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000844
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000845- Replaced most Unicode charmap codecs with new ones using the
846 new Unicode translate string feature in the builtin charmap
847 codec; the codecs were created from the mapping tables available
848 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
849 encodings now include a mapping for the Apple logo)
850
Tim Peterse3547fd2005-12-16 23:13:57 +0000851- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000852
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000853- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000854
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000855- A new AST parser implementation was completed. The abstract
856 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000857 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000858
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000859- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000860 The following code now raises a SyntaxError: foo(a = i for i in range(10))
861
Neal Norwitz708e51a2005-10-03 04:48:15 +0000862- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
863
Neal Norwitz11bd1192005-10-03 00:54:56 +0000864- SF Bug #887946: fix segfault when redirecting stdin from a directory.
865 Provide a warning when a directory is passed on the command line.
866
Neal Norwitz40d37812005-10-02 01:48:49 +0000867- Fix segfault with invalid coding.
868
869- SF bug #772896: unknown encoding results in MemoryError.
870
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000871- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000872 supported a __len__() method which evaluated to False when the iterator
873 was empty.
874
Guido van Rossum630db602005-09-20 18:49:54 +0000875- On 64-bit platforms, when __len__() returns a value that cannot be
876 represented as a C int, raise OverflowError.
877
Skip Montanarof8948ca2005-09-19 03:54:46 +0000878- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000879 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000880
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000881- SF bug #893549: parsing keyword arguments was broken with a few format
882 codes.
883
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000884- Changes donated by Elemental Security to make it work on AIX 5.3
885 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
886 bug #105470: test_pwd fails on 64bit system (Opteron).
887
Guido van Rossum539c6622005-09-14 17:49:54 +0000888- Changes donated by Elemental Security to make it work on HP-UX 11 on
889 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
890
Georg Brandl4550b8d2005-08-26 06:43:52 +0000891- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000892 (fixes bug #1119418).
893
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000894- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
895
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000896- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
897 exceptions that cause a function to exit.
898
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000899- The implementation of set() and frozenset() was revised to use its
900 own internal data structure. Memory consumption is reduced by 1/3
901 and there are modest speed-ups as well. The API is unchanged.
902
Tim Petersde7990b2005-07-17 23:45:23 +0000903- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
904
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000905- SF bug #1229429: PyObject_CallMethod failed to decrement some
906 reference counts in some error exit cases.
907
Tim Petersecc6e6a2005-07-10 22:30:55 +0000908- SF bug #1185883: Python's small-object memory allocator took over
909 a block managed by the platform C library whenever a realloc specified
910 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000911 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000912 portable way to copy data from the C-managed block into Python's
913 small-object space without risking a memory fault. Python's small-object
914 realloc now leaves such blocks under the control of the platform C
915 realloc.
916
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000917- SF bug #1232517: An overflow error was not detected properly when
918 attempting to convert a large float to an int in os.utime().
919
Raymond Hettinger3296e692005-06-29 23:29:56 +0000920- SF bug #1224347: hex longs now print with lowercase letters just
921 like their int counterparts.
922
Michael W. Hudson188d4362005-06-20 16:52:57 +0000923- SF bug #1163563: the original fix for bug #1010677 ("thread Module
924 Breaks PyGILState_Ensure()") broke badly in the case of multiple
925 interpreter states; back out that fix and do a better job (see
926 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
927 for a longer write-up of the problem).
928
Michael W. Hudsondf888462005-06-03 14:41:55 +0000929- SF patch #1180995: marshal now uses a binary format by default when
930 serializing floats.
931
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000932- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
933 the routines that promise to produce IEEE 754 binary representations
934 of floats now simply copy bytes around.
935
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000936- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
937 278.
938
Brett Cannonc3647ac2005-04-26 03:45:26 +0000939- patch #1109424: int, long, float, complex, and unicode now check for the
940 proper magic slot for type conversions when subclassed. Previously the
941 magic slot was ignored during conversion. Semantics now match the way
942 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000943 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000944 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000945 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000946
Barry Warsawc8d907c2005-04-19 23:43:40 +0000947- Descriptors defined in C with a PyGetSetDef structure, where the setter is
948 NULL, now raise an AttributeError when attempting to set or delete the
949 attribute. Previously a TypeError was raised, but this was inconsistent
950 with the equivalent pure-Python implementation.
951
Michael W. Hudson774479c2005-04-18 08:46:17 +0000952- It is now safe to call PyGILState_Release() before
953 PyEval_InitThreads() (note that if there is reason to believe there
954 are multiple threads around you still must call PyEval_InitThreads()
955 before using the Python API; this fix is for extension modules that
956 have no way of knowing if Python is multi-threaded yet).
957
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000958- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
959 disabled caused a crash.
960
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000961- Bug #1165306: instancemethod_new allowed the creation of a method
962 with im_class == im_self == NULL, which caused a crash when called.
963
Tim Petersecc6e6a2005-07-10 22:30:55 +0000964- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000965 fixes the crash seen in bug #1165761
966
Raymond Hettinger96229b12005-03-11 06:49:40 +0000967- Added two new builtins, any() and all().
968
Brett Cannon409d8f22005-03-05 06:47:57 +0000969- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000970 (e.g., ``class C(): pass`` is no longer a syntax error).
971 Patch #1176012 added support to the 'parser' module and 'compiler' package
972 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000973
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000974- Patch #1115086: Support PY_LONGLONG in structmember.
975
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000976- Bug #1155938: new style classes did not check that __init__() was
977 returning None.
978
Tim Petersecc6e6a2005-07-10 22:30:55 +0000979- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000980 ('\') with a specific error message.
981
Martin v. Löwisff232d72005-03-03 09:24:38 +0000982- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
983
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000984- Bug #1124295: the __name__ attribute of file objects was
985 inadvertently made inaccessible in restricted mode.
986
Tim Petersecc6e6a2005-07-10 22:30:55 +0000987- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000988 an ferror() call.
989
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000990- min() and max() now support key= arguments with the same meaning as in
991 list.sort().
992
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000993- The peephole optimizer now performs simple constant folding in expressions:
994 (2+3) --> (5).
995
Raymond Hettingera422c342005-01-11 03:03:27 +0000996- set and frozenset objects can now be marshalled. SF #1098985.
997
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000998- Bug #1077106: Poor argument checking could cause memory corruption
999 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001000
Jeremy Hyltonab630502005-02-04 18:44:06 +00001001- The parser did not complain about future statements in illegal
1002 positions. It once again reports a syntax error if a future
1003 statement occurs after anything other than a doc string.
1004
Neil Schemenauercf52c072005-08-12 17:34:58 +00001005- Change the %s format specifier for str objects so that it returns a
1006 unicode instance if the argument is not an instance of basestring and
1007 calling __str__ on the argument returns a unicode instance.
1008
Tim Petersf4e69282006-02-27 17:15:31 +00001009- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1010 current thread state when the auto-GIL-state machinery knows about
1011 it (since the thread state is being deleted, continuing to remember it
1012 can't help, but can hurt if another thread happens to get created with
1013 the same thread id).
1014
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001015Extension Modules

1040
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001041- The unicodedata module was updated to the 4.1 version of the Unicode

1043 for applications that require this specific version (such as IDNA).
1044
Neal Norwitzb62c4332006-03-04 18:35:47 +00001045- The timing module is no longer built by default. It was deprecated

1193 This allows islice() to work more readily with slices:
1194 islice(s.start, s.stop, s.step)
1195
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001196- datetime.datetime() now has a strptime class method which can be used to

1204
Nick Coghlan43832302006-04-23 17:04:07 +00001205- PEP 338: new module runpy defines a run_module function to support
1206 executing modules which provide access to source code or a code object
1207 via the PEP 302 import mechanisms.
1208
Anthony Baxter93f5b932006-04-03 08:05:07 +00001209- The email module's parsedate_tz function now sets the daylight savings
1210 flag to -1 (unknown) since it can't tell from the date whether it should
1211 be set.
1212
Fred Drakead5177c2006-04-01 22:14:43 +00001213- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
1214 now sport attributes that provide access to the parts of the result.
1215

1217 in attribute values.
1218
Anthony Baxterc51ee692006-04-01 00:57:31 +00001219- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001220 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001221 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001222 module will not be built.
1223
Tim Petersc17976e2006-04-01 00:26:53 +00001224- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1225 aren't officially supported here, and trying to use them will probably
1226 raise an exception some day. But dicts have been allowed, and "mostly
1227 worked", so support for them won't go away without warning.
1228
Georg Brandl338ef7d2006-03-31 18:42:16 +00001229- Bug #1445068: getpass.getpass() can now be given an explicit stream
1230 argument to specify where to write the prompt.
1231

1239
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001240- Queue.Queue objects now support .task_done() and .join() methods
1241 to make it easier to monitor when daemon threads have completed
1242 processing all enqueued tasks. Patch #1455676.
1243
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001244- popen2.Popen objects now preserve the command in a .cmd attribute.
1245

1247
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001248- email 4.0 package now integrated. This is largely the same as the email 3.0
1249 package that was included in Python 2.3, except that PEP 8 module names are
1250 now used (e.g. mail.message instead of email.Message). The MIME classes
1251 have been moved to a subpackage (e.g. email.mime.text instead of
1252 email.MIMEText). The old names are still supported for now. Several
1253 deprecated Message methods have been removed and lots of bugs have been
1254 fixed. More details can be found in the email package documentation.
1255
Walter Dörwald40108c92006-03-27 08:15:44 +00001256- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1257 (a subclass of tuple) that provides incremental decoders and encoders
1258 (a way to use stateful codecs without the stream API). Python functions
1259 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1260 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1261 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001262
Walter Dörwald067db482006-03-15 22:17:27 +00001263- Patch #1359365: Calling next() on a closed StringIO.String object raises
1264 a ValueError instead of a StopIteration now (like file and cString.String do).
1265 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1266 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001267

1274 grew an optional 'generation' argument.
1275
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001276- A library msilib to generate Windows Installer files, and a distutils

1341 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1342 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1343 Ronald L. Rivest offered this advice for Python:
1344
1345 "The consensus of researchers in this area (at least as
1346 expressed at the NIST Hash Function Workshop 10/31/05),
1347 is that SHA-256 is a good choice for the time being, but
1348 that research should continue, and other alternatives may
1349 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001350
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001351- Added a subset of Fredrik Lundh's ElementTree package. Available

Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001447 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001448 the generate_tokens() function now accepts a callable argument that
1449 terminates by raising StopIteration.

Georg Brandl9166e1a2005-06-04 09:20:03 +00001451- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1452
Georg Brandl268e61c2005-06-03 14:28:50 +00001453- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1454 component of the path.
1455
Skip Montanaro174dd222005-05-14 20:54:16 +00001456- Patch #1120353: The xmlrpclib module provides better, more transparent,
1457 support for datetime.{datetime,date,time} objects. With use_datetime set
1458 to True, applications shouldn't have to fiddle with the DateTime wrapper
1459 class at all.
1460
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001461- distutils.commands.upload was added to support uploading distribution
1462 files to PyPI.
1463
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001464- distutils.commands.register now encodes the data as UTF-8 before posting
1465 them to PyPI.
1466
Raymond Hettinger267b8682005-03-27 10:47:39 +00001467- decimal operator and comparison methods now return NotImplemented
1468 instead of raising a TypeError when interacting with other types. This
1469 allows other classes to implement __radd__ style methods and have them
1470 work as expected.
1471
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001472- Bug #1163325: Decimal infinities failed to hash. Attempting to
1473 hash a NaN raised an InvalidOperation instead of a TypeError.
1474
Tim Petersecc6e6a2005-07-10 22:30:55 +00001475- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001476 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1477
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001478- Patch #1043890: Add extractall method to tarfile.
1479
Martin v. Löwisc72dd382005-03-04 13:50:17 +00001480- Patch #1075887: Don't require MSVC in distutils if there is nothing
1481 to build.
1482
Martin v. Löwis637431b2005-03-03 23:12:42 +00001483- Patch #1103407: Properly deal with tarfile iterators when untarring
1484 symbolic links on Windows.
1485
Tim Petersecc6e6a2005-07-10 22:30:55 +00001486- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001487 profile.py if available.
1488
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001489- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1490
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001491- Patch #1117454: Remove code to special-case cookies without values
1492 in LWPCookieJar.
1493
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001494- Patch #1117339: Add cookielib special name tests.
1495
Martin v. Löwise869eb12005-03-03 09:46:07 +00001496- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1497
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001498- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1499
Martin v. Löwisdf241532005-03-03 08:17:42 +00001500- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1501
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001502- Patch #1104111: Alter setup.py --help and --help-commands.
1503
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001504- Patch #1121234: Properly cleanup _exit and tkerror commands.
1505
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001506- Patch #1049151: xdrlib now unpacks booleans as True or False.
1507
Raymond Hettingerbab41432005-02-05 01:31:19 +00001508- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1509
Guido van Rossumd0641422005-02-03 15:01:24 +00001510- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1511 disables recursive traversal through instance attributes, which can
1512 be exploited in various ways.
1513
Tim Peterse3547fd2005-12-16 23:13:57 +00001514- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001515 flags on the HTTP listening socket.
1516
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001517- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1518 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1519
Tim Peterse3547fd2005-12-16 23:13:57 +00001520- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001521 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1522
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001523- Bug #1110478: Revert os.environ.update to do putenv again.
1524
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001525- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1526
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001527- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1528
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001529- Enhancements to the csv module:
1530
1531 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001532 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001533 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001534 + Dialect parameter parsing has been re-implemented to improve error
1535 reporting.
1536 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1537 dictates.
1538 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001539 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001540 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001541 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1542 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001543 + reader now allows \r characters to be quoted (previously it only allowed
1544 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001545 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001546 + Dialect classes passed to the module are no longer instantiated by
1547 the module before being parsed (the former validation scheme required
1548 this, but the mechanism was unreliable).
1549 + The dialect registry now contains instances of the internal
1550 C-coded dialect type, rather than references to python objects.
1551 + the internal c-coded dialect type is now immutable.
1552 + register_dialect now accepts the same keyword dialect specifications
1553 as the reader and writer, allowing the user to register dialects
1554 without first creating a dialect class.
1555 + a configurable limit to the size of parsed fields has been added -
1556 previously, an unmatched quote character could result in the entire
1557 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001558 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001559 the parser field size limit (returning the former limit). The initial
1560 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001561 + A line_num attribute has been added to the reader object, which tracks
1562 the number of lines read from the source iterator. This is not
1563 the same as the number of records returned, as records can span
1564 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001565 + reader and writer objects were not being registered with the cyclic-GC.
1566 This has been fixed.
1567
Brett Cannone6539c42005-01-08 02:43:53 +00001568- _DummyThread objects in the threading module now delete self.__block that is
1569 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1570 lock primitives tend to be limited in number and thus should not be wasted on
1571 a _DummyThread object. Fixes bug #1089632.
1572
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001573- The imghdr module now detects Exif files.
1574
Raymond Hettinger6065d322004-12-20 23:51:53 +00001575- StringIO.truncate() now correctly adjusts the size attribute.
1576 (Bug #951915).
1577
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001578- locale.py now uses an updated locale alias table (built using
1579 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1580 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001581 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001582
Raymond Hettinger3557f422004-12-07 12:02:02 +00001583- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1584
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001585- the pickle module no longer accepts the deprecated None option in the
1586 args tuple returned by __reduce__().
1587
Brett Cannon84667c02004-12-07 03:25:18 +00001588- optparse now optionally imports gettext. This allows its use in setup.py.
1589
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001590- the pickle module no longer uses the deprecated bin parameter.
1591
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001592- the shelve module no longer uses the deprecated binary parameter.
1593
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001594- the pstats module no longer uses the deprecated ignore() method.
1595
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001596- the filecmp module no longer uses the deprecated use_statcache argument.
1597
Raymond Hettinger664347b2004-12-04 21:21:53 +00001598- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1599 extended or overridden by subclasses. Formerly, the subclassed method would
1600 be ignored by the rest of the module. (Bug #1078905).
1601
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001602- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001603 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001604
Walter Dörwald36733692004-12-22 12:50:50 +00001605- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1606 once when a size argument is given. This prevents a buffer overflow in the
1607 tokenizer with very long source lines.
1608
Barry Warsaw538561e2006-01-01 21:48:54 +00001609- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1610 immediately after creating the object, without any intervening
1611 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001612
Skip Montanaro05885812005-01-16 20:48:27 +00001613- The reconvert.quote function can now emit triple-quoted strings. The
1614 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001615
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001616- ``UserString.MutableString`` now supports negative indices in
1617 ``__setitem__`` and ``__delitem__``
1618
Greg Ward40407942005-03-05 02:53:17 +00001619- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1620 correctly.
1621
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001622- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1623 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1624 character even if the user has passed a size parameter to get a proper
1625 line ending. Remove the special handling of a "\r\n" that has been split
1626 between two lines.
1627
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001628- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1629 about illegal code points. The codec now supports PEP 293 style error
1630 handlers.
1631
Walter Dörwald78a78b02005-09-01 12:04:29 +00001632- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001633 from the input stream, so that the output is a byte string in the correct
1634 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001635
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001636- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1637 considering it exactly like a '*'.
1638
Walter Dörwald007f8df2005-10-09 19:42:27 +00001639- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1640 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001641
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001642- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1643
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001644- Patch #1413711: Certain patterns of differences were making difflib
1645 touch the recursion limit.
1646
Walter Dörwald58917a62006-03-31 15:26:22 +00001647- Bug #947906: An object oriented interface has been added to the calendar
1648 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001649 called as a script (e.g. via ``python -mcalendar``). Localized month and
1650 weekday names can be ouput (even if an exotic encoding is used) using
1651 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001652

1654-----
1655
Neal Norwitz602d3392006-03-31 08:21:40 +00001656- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1657 by using -mieee gcc option.
1658

1660
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001661- Build support for Win64-AMD64 was added.
1662
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001663- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1664
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001665- Patch #881820: look for openpty and forkpty also in libbsd.
1666
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001667- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1668 The zlib module is now builtin on Windows.
1669
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001670- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1671
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001672- Bug #1189330: configure did not correctly determine the necessary
1673 value of LINKCC if python was built with GCC 4.0.
1674
Trent Mick8321b422005-07-26 02:29:21 +00001675- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1676 vulnerability in zlib 1.2.1 and 1.2.2.
1677
Brett Cannon08cd5982005-04-24 22:26:38 +00001678- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1679 flags that change binary compatibility. Changes were also made to
1680 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001681 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001682
Bob Ippolitoed233462005-03-29 13:47:59 +00001683- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1684 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1685 no longer exists). This configure patch makes things right.
1686
Martin v. Löwise2713be2005-03-08 15:03:08 +00001687- Bug #1158607: Build with --disable-unicode again.
1688
Brett Cannon46d96232005-02-16 00:07:19 +00001689- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1690 defined. Discovered as a result of not being able to build on OS X.
1691
Brett Cannon516592f2004-12-07 00:42:59 +00001692- setup.py now uses the directories specified in LDFLAGS using the -L option
1693 and in CPPFLAGS using the -I option for adding library and include
1694 directories, respectively, for compiling extension modules against. This has
1695 led to the core being compiled using the values in CPPFLAGS. It also removes
1696 the need for the special-casing of both DarwinPorts and Fink for darwin since
1697 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1698 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1699 Fink, ``-I/opt/local/include`` for DarwinPorts).
1700
Brett Cannon43802422005-02-10 20:48:03 +00001701- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1702 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1703 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1704 Closes bug #1096244. Thanks Gregory Bond.

1707-----
1708
Tim Petersc9d78aa2006-03-26 23:27:58 +00001709- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1710 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1711 is obtained via the ``PyObject_`` family, it must be released via the
1712 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1713 always been officially true, but when Python's small-object allocator was
1714 introduced, an attempt was made to cater to a few extension modules
1715 discovered at the time that obtained memory via ``PyObject_New`` but
1716 released it via ``PyMem_DEL``. It's years later, and if such code still
1717 exists it will fail now (probably with segfaults, but calling wrong
1718 low-level memory management functions can yield many symptoms).

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001724- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1725 mapping argument now. This string is used as a mapping table. Byte values
1726 greater than the length of the string and 0xFFFE are treated as undefined
1727 mappings.
