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 Heller6e1ad2e2006-07-13 17:05:13 +000028- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000029 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000030 /dev/null in certain cases; this is now fixed.
31
Thomas Heller47d7a062006-07-12 08:43:47 +000032- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
33 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000034
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000035- Because of a misspelled preprocessor symbol, ctypes was always
36 compiled without thread support; this is now fixed.

43Core and builtins
44-----------------
45
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000046- Bug #1441486: The literal representation of -(sys.maxint - 1)
47 again evaluates to a int object, not a long.
48
Neil Schemenauer0e07b602006-07-09 16:16:34 +000049- Bug #1501934: The scope of global variables that are locally assigned
50 using augmented assignment is now correctly determined.
51
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000052- Bug #927248: Recursive method-wrapper objects can now safely
53 be released.
54
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000055- Bug #1417699: Reject locale-specific decimal point in float()
56 and atof().
57
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000058- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
59 omit a default "error" argument for NULL pointer. This allows
60 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000061
Neal Norwitzfb48afa2006-07-08 05:31:37 +000062- Bug #1519018: 'as' is now validated properly in import statements.
63
Neal Norwitz28746ab2006-07-09 22:14:42 +000064- On 64 bit systems, int literals that use less than 64 bits are
65 now ints rather than longs.
66
Neal Norwitzed657552006-07-10 00:04:44 +000067- Bug #1512814, Fix incorrect lineno's when code at module scope
68 started after line 256.
69
Tim Peters32a83612006-07-10 21:08:24 +000070- New function ``sys._current_frames()`` returns a dict mapping thread
71 id to topmost thread stack frame. This is for expert use, and is
72 especially useful for debugging application deadlocks. The functionality
73 was previously available in Fazal Majid's ``threadframe`` extension
74 module, but it wasn't possible to do this in a wholly threadsafe way from
75 an extension.

81
Tim Peters32a83612006-07-10 21:08:24 +000082- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +000083 environment variable to be set in order to the SDK environment
84 for finding the compiler, include files, etc.
85
Martin v. Löwis388a8c22006-07-06 19:28:03 +000086- Bug #1515998: Properly generate logical ids for files in bdist_msi.
87
Nick Coghlan2d792252006-07-06 13:47:18 +000088- warnings.py now ignores ImportWarning by default
89
Thomas Woutersadd19112006-07-05 11:03:49 +000090- string.Template() now correctly handles tuple-values. Previously,
91 multi-value tuples would raise an exception and single-value tuples would
92 be treated as the value they contain, instead.
93
Martin v. Löwisede77f52006-07-03 13:01:35 +000094- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
95 even if some data are received.
96
Martin v. Löwis45482392006-07-03 12:28:58 +000097- Bug #1267547: Put proper recursive setup.py call into the

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000104 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000105
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000106- Bug #1514703: Only setup canvas window in turtle when the canvas
107 is created.
108
Martin v. Löwis7596e832006-07-01 15:33:37 +0000109- Bug #1513223: .close() of a _socketobj now releases the underlying
110 socket again, which then gets closed as it becomes unreferenced.
111
Fred Drake10497c82006-06-29 02:57:48 +0000112- Bug #1504333: Make sgmllib support angle brackets in quoted
113 attribute values.
114
115- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
116 sgmllib ('[' and ']' were not accepted).
117
Georg Brandl1be63af2006-06-28 20:23:25 +0000118- Fix a bug in the turtle module's end_fill function.
119
Brett Cannon53ab5b72006-06-22 16:49:14 +0000120- Bug #1510580: The 'warnings' module improperly required that a Warning
121 category be either a types.ClassType and a subclass of Warning. The proper
122 check is just that it is a subclass with Warning as the documentation states.
123
Georg Brandlad29e632006-06-21 17:45:17 +0000124- The compiler module now correctly compiles the new try-except-finally
125 statement (bug #1509132).
126
Neal Norwitz60373cd2006-06-22 06:30:50 +0000127- The wsgiref package is now installed properly on Unix.
128
Vinay Sajip28e57612006-07-01 10:45:20 +0000129- A bug was fixed in logging.config.fileConfig() which caused a crash on
130 shutdown when fileConfig() was called multiple times.
131
Gerhard Häring762fbd32006-07-02 17:48:30 +0000132- The sqlite3 module did cut off data from the SQLite database at the first
133 null character before sending it to a custom converter. This has been fixed
134 now.
135
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000136Extension Modules
137-----------------
138
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000139- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
140 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
141 The patch makes sockets use poll() internally where available.
142
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000143- Assigning None to pointer type fields in ctypes structures possible
144 overwrote the wrong fields, this is fixed now.
145
146- Fixed a segfault in _ctypes when ctypes.wintypes were imported
147 on non-Windows platforms.
148
149- Bug #1518190: The ctypes.c_void_p constructor now accepts any
150 integer or long, without range checking.
151
152- Patch #1517790: It is now possible to use custom objects in the ctypes
153 foreign function argtypes sequence as long as they provide a from_param
154 method, no longer is it required that the object is a ctypes type.
155
156- The '_ctypes' extension module now works when Python is configured
157 with the --without-threads option.
158
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000159- Bug #1513646: os.access on Windows now correctly determines write
160 access, again.
161
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000162- Bug #1512695: cPickle.loads could crash if it was interrupted with
163 a KeyboardInterrupt.
164
Neal Norwitza12aa882006-07-06 06:45:08 +0000165- Bug #1296433: parsing XML with a non-default encoding and
166 a CharacterDataHandler could crash the interpreter in pyexpat.
167
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000168- Patch #1516912: improve Modules support for OpenVMS.
169
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000170Build
171-----
172
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000173- Automate Windows build process for the Win64 SSL module.
174
Tim Peters32a83612006-07-10 21:08:24 +0000175- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000176 Previously, the slight difference could cause compilation errors of the
177 'zlib' module on systems with more than one version of zlib.
178
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000179- The MSI compileall step was fixed to also support a TARGETDIR
180 with spaces in it.
181
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000182- Bug #1517388: sqlite3.dll is now installed on Windows independent
183 of Tcl/Tk.
184
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000185- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000186 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000187
Neal Norwitzb15ac312006-06-29 04:10:08 +0000188Tests
189-----
190
191- Call os.waitpid() at the end of tests that spawn child processes in order
192 to minimize resources (zombies).

Nick Coghlan2d792252006-07-06 13:47:18 +0000197- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
198 documentation for the warnings module.
199
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000200- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000206
Anthony Baxterd1136802006-06-19 12:04:15 +0000207*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000208
209Core and builtins
210-----------------
211
Georg Brandla56b9152006-06-19 06:35:54 +0000212- Patch #1507676: Error messages returned by invalid abstract object operations
213 (such as iterating over an integer) have been improved and now include the
214 type of the offending object to help with debugging.
215
Brett Cannonea3912b2006-06-13 21:46:41 +0000216- Bug #992017: A classic class that defined a __coerce__() method that returned
217 its arguments swapped would infinitely recurse and segfault the interpreter.
218
Neal Norwitz909eb122006-06-12 02:13:21 +0000219- Fix the socket tests so they can be run concurrently.
220
Neal Norwitzb9845e72006-06-12 02:11:18 +0000221- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000222 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000223
Brett Cannon22565aa2006-06-09 22:31:23 +0000224- Bug #532646: object.__call__() will continue looking for the __call__
225 attribute on objects until one without one is found. This leads to recursion
226 when you take a class and set its __call__ attribute to an instance of the
227 class. Originally fixed for classic classes, but this fix is for new-style.
228 Removes the infinite_rec_3 crasher.
229
Georg Brandl24250812006-06-09 18:45:48 +0000230- The string and unicode methods startswith() and endswith() now accept
231 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
232
Brett Cannonde3b0522006-06-08 17:00:45 +0000233- Buffer objects, at the C level, never used the char buffer
234 implementation even when the char buffer for the wrapped object was
235 explicitly requested (originally returned the read or write buffer).
236 Now a TypeError is raised if the char buffer is not present but is
237 requested.
238
Georg Brandlddbaa662006-06-04 21:56:52 +0000239- Patch #1346214: Statements like "if 0: suite" are now again optimized
240 away like they were in Python 2.4.
241
Georg Brandlb7c8f542006-05-27 12:30:25 +0000242- Builtin exceptions are now full-blown new-style classes instead of
243 instances pretending to be classes, which speeds up exception handling
244 by about 80% in comparison to 2.5a2.
245
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000246- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
247 Unicode 4.1.
248
Georg Brandlf4ef1162006-05-26 18:03:31 +0000249- Patch #921466: sys.path_importer_cache is now used to cache valid and
250 invalid file paths for the built-in import machinery which leads to
251 fewer open calls on startup.
252
Tim Peters696cf432006-05-24 21:10:40 +0000253- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
254 of-2 bases. The largest speedup is for inputs with about 1000 decimal
255 digits. Conversion from non-power-of-2 bases remains quadratic-time in
256 the number of input digits (it was and remains linear-time for bases
257 2, 4, 8, 16 and 32).
258
Tim Petersb713ec22006-05-23 18:45:30 +0000259- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
260 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
261 an integer close to ``sys.maxint``. This was repaired by patch
262 #1335972, which also gives a nice speedup.
263
Richard Jonescebbefc2006-05-23 18:28:17 +0000264- Patch #1337051: reduced size of frame objects.
265
266- PyErr_NewException now accepts a tuple of base classes as its
267 "base" parameter.
268
Richard Jones7c88dcc2006-05-23 10:37:38 +0000269- Patch #876206: function call speedup by retaining allocated frame
270 objects.
271
Georg Brandl7b90e162006-05-18 07:01:27 +0000272- Bug #1462152: file() now checks more thoroughly for invalid mode
273 strings and removes a possible "U" before passing the mode to the
274 C library function.
275
Neal Norwitz1004a532006-05-15 07:17:23 +0000276- Patch #1488312, Fix memory alignment problem on SPARC in unicode
277
Neal Norwitz373f0a72006-05-15 07:04:36 +0000278- Bug #1487966: Fix SystemError with conditional expression in assignment
279
Martin v. Löwis879768d2006-05-11 13:28:43 +0000280- WindowsError now has two error code attributes: errno, which carries
281 the error values from errno.h, and winerror, which carries the error
282 values from winerror.h. Previous versions put the winerror.h values
283 (from GetLastError()) into the errno attribute.
284
Martin v. Löwis77736712006-05-04 05:51:03 +0000285- Patch #1475845: Raise IndentationError for unexpected indent.
286
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000287- Patch #1479181: split open() and file() from being aliases for each other.
288
Tim Peters44bd9862006-06-01 13:49:23 +0000289- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
290 methods were always silently ignored by dictionaries when comparing keys.
291 They are now passed through (except when using the C API function
292 ``PyDict_GetItem()``, whose semantics did not change).
293
294- Bug #1456209: In some obscure cases it was possible for a class with a
295 custom ``__eq__()`` method to confuse dict internals when class instances
296 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
297 No, you don't have any code that did this ;-)

303
304- Patch #1462338: Upgrade pyexpat to expat 2.0.0
305
Brett Cannon6ee7d012006-06-08 16:23:04 +0000306- Change binascii.hexlify to accept a read-only buffer instead of only a char
307 buffer and actually follow its documentation.
308
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000309- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
310
Nick Coghlanc649ec52006-05-29 12:43:05 +0000311- Patch #1478788 (modified version): The functional extension module has
312 been renamed to _functools and a functools Python wrapper module added.
313 This provides a home for additional function related utilities that are
314 not specifically about functional programming. See PEP 309.
315
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000316- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +0000320- Patch #1435422: zlib's compress and decompress objects now have a
321 copy() method.
322
Andrew MacIntyre92913322006-06-13 15:04:24 +0000323- Patch #1454481: thread stack size is now tunable at runtime for thread
324 enabled builds on Windows and systems with Posix threads support.
325
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000326- On Win32, os.listdir now supports arbitrarily-long Unicode path names
327 (up to the system limit of 32K characters).
328
329- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
330 As a result, these functions now raise WindowsError instead of OSError.
331
Tim Peters7a822da2006-05-25 21:50:17 +0000332- ``time.clock()`` on Win64 should use the high-performance Windows
333 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
334 Windows platforms).
335
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000336- Calling Tk_Init twice is refused if the first call failed as that
337 may deadlock.
338
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000339- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
340 accept it without potentially using an uninitialized pointer.
341
342- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
343 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
344 patch numbers 1494885 and 1494902]

Gregory P. Smith372b5832006-06-05 18:48:21 +0000346- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000347 [pybsddb project SF patch number 1466734]
348
Gregory P. Smith372b5832006-06-05 18:48:21 +0000349- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
350 parameter is supplied. [SF pybsddb bug #1477863]
351
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000352- bsddb: the __len__ method of a DB object has been fixed to return correct
353 results. It could previously incorrectly return 0 in some cases.
354 Fixes SF bug 1493322 (pybsddb bug 1184012).
355
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000356- bsddb: the bsddb.dbtables Modify method now raises the proper error and
357 aborts the db transaction safely when a modifier callback fails.
358 Fixes SF python patch/bug #1408584.
359
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000360- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000361 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000362 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
363 database calls that would previously deadlock. [SF python bug #775414]
364
Vinay Sajip28e57612006-07-01 10:45:20 +0000365- Patch #1446489: add support for the ZIP64 extensions to zipfile.

387 mime.types file for determining MIME types.
388
Georg Brandl2605ca82006-06-14 06:08:31 +0000389- Bug #1339007: Shelf objects now don't raise an exception in their
390 __del__ method when initialization failed.
391
Martin v. Löwisd8251432006-06-14 05:21:04 +0000392- Patch #1455898: The MBCS codec now supports the incremental mode for
393 double-byte encodings.
394
Tim Peters43898b42006-06-14 04:09:25 +0000395- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
396 guarantee that adjacent triples in the return list always describe
397 non-adjacent blocks. Previously, a pair of matching blocks could end
398 up being described by multiple adjacent triples that formed a partition
399 of the matching pair.
400
Greg Ward0e0c9f42006-06-11 16:24:11 +0000401- Bug #1498146: fix optparse to handle Unicode strings in option help,
402 description, and epilog.
403
Greg Wardd1c797e2006-06-11 14:42:41 +0000404- Bug #1366250: minor optparse documentation error.

407 clarify docs.
408
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000409- The wsgiref package has been added to the standard library.
410
Nick Coghlan676725d2006-06-08 13:54:49 +0000411- The functions update_wrapper() and wraps() have been added to the functools
412 module. These make it easier to copy relevant metadata from the original
413 function when writing wrapper functions.
414
Tim Petersd6a9eef2006-06-05 01:48:21 +0000415- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
416 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000417
Martin v. Löwis3f767792006-06-04 19:36:28 +0000418- Patch #1359618: Speed up charmap encoder by using a trie structure
419 for lookup.
420
Tim Petersd609b1a2006-06-02 23:22:51 +0000421- The functions in the ``pprint`` module now sort dictionaries by key
422 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
423 if and only if its display required more than one line, although that
424 wasn't documented. The new behavior increases predictability; e.g.,
425 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
426
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000427- Patch #1497027: try HTTP digest auth before basic auth in urllib2

434
Bob Ippolito7298f272006-05-23 18:43:47 +0000435- Patch #1281707: speed up gzip.readline.
436
Georg Brandlb89316f2006-05-17 15:51:16 +0000437- Patch #1180296: Two new functions were added to the locale module:
438 format_string() to get the effect of "format % items" but locale-aware,
439 and currency() to format a monetary number with currency sign.
440
Georg Brandle3a25832006-05-17 14:56:04 +0000441- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
442 and several features added, such as speed and geometry control.
443
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000444- Patch #1488881: add support for external file objects in bz2 compressed
445 tarfiles.
446
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000447- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
448 stdout arguments, making it possible to redirect input and output
449 for remote debugging.
450
451- Patch #1484695: Update the tarfile module to version 0.8. This fixes
452 a couple of issues, notably handling of long file names using the
453 GNU LONGNAME extension.
454
455- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
456 new flag when ``name`` is already the name of an option flag.
457
458- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
459 package.
460
461- Patch #1472854: make the rlcompleter.Completer class usable on non-
462 UNIX platforms.

499
500*Release date: 27-APR-2006*
501
502Core and builtins
503-----------------
504
Thomas Heller1b046642006-04-18 18:51:06 +0000505- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
506 by converting these apis from macros into exported functions again:
507
508 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
509 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
510 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
511 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
512 PyRun_String Py_CompileString
513
Martin v. Löwis45294a92006-04-18 06:24:08 +0000514- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
515
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000516- All uses of PyStructSequence_InitType have been changed to initialize
517 the type objects only once, even if the interpreter is initialized
518 multiple times.
519
Neal Norwitz61546162006-04-14 05:20:28 +0000520- Bug #1454485, array.array('u') could crash the interpreter. This was
521 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
522 to unicode when it didn't make sense. 'u#' now requires a unicode string.
523
524- Py_UNICODE is unsigned. It was always documented as unsigned, but
525 due to a bug had a signed value in previous versions.
526
Tim Peters3a5e8b12006-04-11 01:44:07 +0000527- Patch #837242: ``id()`` of any Python object always gives a positive
528 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
529 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000530 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000531 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000532
Tim Peters3a5e8b12006-04-11 01:44:07 +0000533 def __hash__(self):
534 return id(self) # WRONG
535
536 because a hash result must be a (short) Python int but it was always
537 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000538 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000539 was always usable as a hash value before this patch. That's no longer
540 necessarily so.
541
542- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000543 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000544 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000545 #1454844)
546
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000547- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
548 involving generators that have paused outside of any ``try`` or ``with``
549 blocks. (In 2.5a1, a paused generator that was part of a reference
550 cycle could not be garbage collected, regardless of whether it was
551 paused in a ``try`` or ``with`` block.)

577-------
578
Tim Peters711bf302006-04-25 03:31:36 +0000579- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
580 a doctest to be skipped (the code is not run, and the expected output
581 or exception is ignored).
582
Nick Coghlanda2268f2006-04-24 04:37:15 +0000583- Fixed contextlib.nested to cope with exceptions being raised and
584 caught inside exit handlers.

Greg Wardab05edc2006-04-23 03:47:58 +0000586- Updated optparse module to Optik 1.5.1 (allow numeric constants in
587 hex, octal, or binary; add ``append_const`` action; keep going if
588 gettext cannot be imported; added ``OptionParser.destroy()`` method;
589 added ``epilog`` for better help generation).
590
Tim Peters21fbd572006-04-21 21:18:10 +0000591- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
592 called from a thread spawned as a side effect of importing a module.
593
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000594- The pydoc module now supports documenting packages contained in
595 .zip or .egg files.
596
597- The pkgutil module now has several new utility functions, such
598 as ``walk_packages()`` to support working with packages that are either
599 in the filesystem or zip files.
600
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000601- The mailbox module can now modify and delete messages from
602 mailboxes, in addition to simply reading them. Thanks to Gregory
603 K. Johnson for writing the code, and to the 2005 Google Summer of
604 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000605
Tim Petersc7605f22006-04-17 21:12:33 +0000606- The ``__del__`` method of class ``local`` in module ``_threading_local``
607 returned before accomplishing any of its intended cleanup.
608
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000609- Patch #790710: Add breakpoint command lists in pdb.

614
Anthony Baxtere29002c2006-04-12 12:07:31 +0000615- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
616 Windows. Bug #1469163.
617
Phillip J. Eby47032112006-04-11 01:07:43 +0000618- The warnings, linecache, inspect, traceback, site, and doctest modules
619 were updated to work correctly with modules imported from zipfiles or
620 via other PEP 302 __loader__ objects.
621

636 the library.
637
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000638- Patch #1470875: Building Python with MS Free Compiler
639
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000640- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000641
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000642- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
643 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000644 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000645 CXX from --with-cxx-main, see description in README.
646
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000647- Patch #1429775: Link extension modules with the shared libpython.
648
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000649- Fixed a libffi build problem on MIPS systems.
650
Tim Peters8931ff12006-05-13 23:28:20 +0000651- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
652 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
653 and "%zu" for unsigned integers of type ``size_t``.
654
Anthony Baxter51bcb682006-04-05 14:51:42 +0000655Tests
656-----
657
Nick Coghlanda2268f2006-04-24 04:37:15 +0000658- test_contextlib now checks contextlib.nested can cope with exceptions
659 being raised and caught inside exit handlers.
660
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000661- test_cmd_line now checks operation of the -m and -c command switches
662
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000663- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
664 it separately and by hand. It also wasn't cleaning up its changes to
665 the current Decimal context.
666
Thomas Woutersabd08882006-04-26 15:53:30 +0000667- regrtest.py now has a -M option to run tests that test the new limits of
668 containers, on 64-bit architectures. Running these tests is only sensible
669 on 64-bit machines with more than two gigabytes of memory. The argument
670 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000678Documentation
679-------------
680
Tim Petersb06d28c2006-05-12 01:57:59 +0000681- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
682
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000683- PEP 343: Added Context Types section to the library reference
684 and attempted to bring other PEP 343 related documentation into
685 line with the implementation and/or python-dev discussions.
686
Tim Peters8dc73d22006-04-24 02:03:16 +0000687- Bug #1337990: clarified that ``doctest`` does not support examples
688 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000691What's New in Python 2.5 alpha 1?
692=================================
693
Anthony Baxterebed3f62006-04-03 15:03:44 +0000694*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000695
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000696Core and builtins
697-----------------
698
Nick Coghlan43832302006-04-23 17:04:07 +0000699- PEP 338: -m command line switch now delegates to runpy.run_module
700 allowing it to support modules in packages and zipfiles
701
Martin v. Löwisc661b882006-04-20 04:54:23 +0000702- On Windows, .DLL is not an accepted file name extension for
703 extension modules anymore; extensions are only found if they
704 end in .PYD.
705
Martin v. Löwisea62d252006-04-03 10:56:49 +0000706- Bug #1421664: sys.stderr.encoding is now set to the same value as
707 sys.stdout.encoding.
708
Neal Norwitz92e212f2006-04-03 04:48:37 +0000709- __import__ accepts keyword arguments.
710
Georg Brandlccadf842006-03-31 18:54:53 +0000711- Patch #1460496: round() now accepts keyword arguments.
712
Anthony Baxter262c00a2006-03-30 10:53:17 +0000713- Fixed bug #1459029 - unicode reprs were double-escaped.
714
Hye-Shik Changd478f342006-03-23 12:32:36 +0000715- Patch #1396919: The system scope threads are reenabled on FreeBSD
716 5.4 and later versions.
717
Neal Norwitze98ccf62006-03-23 05:39:47 +0000718- Bug #1115379: Compiling a Unicode string with an encoding declaration
719 now gives a SyntaxError.
720
Georg Brandlabd1ff82006-03-18 07:59:59 +0000721- Previously, Python code had no easy way to access the contents of a
722 cell object. Now, a ``cell_contents`` attribute has been added
723 (closes patch #1170323).
724
Tim Peterscf79aac2006-03-16 01:14:46 +0000725- Patch #1123430: Python's small-object allocator now returns an arena to
726 the system ``free()`` when all memory within an arena becomes unused
727 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
728 freed. Some applications will see a drop in virtual memory size now,
729 especially long-running applications that, from time to time, temporarily
730 use a large number of small objects. Note that when Python returns an
731 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000732 platform C library will in turn return that memory to the operating system.
733 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000734 appears to be effective at least on Microsoft C and gcc-based systems.
735 Thanks to Evan Jones for hard work and patience.
736
Georg Brandl533ff6f2006-03-08 18:09:27 +0000737- Patch #1434038: property() now uses the getter's docstring if there is
738 no "doc" argument given. This makes it possible to legitimately use
739 property() as a decorator to produce a read-only property.
740
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000741- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
742 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
743 of requiring an int or long in slicing and a few other contexts, enabling
744 other objects (e.g. Numeric Python's integers) to be used as slice indices.
745
Neal Norwitz995acdf2006-03-07 05:01:00 +0000746- Fixed various bugs reported by Coverity's Prevent tool.
747
Brett Cannonbf364092006-03-01 04:25:17 +0000748- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
749 new exception base class, BaseException, which has a new message attribute.
750 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
751 Raising a string exception now raises a DeprecationWarning.
752
Thomas Woutersfb609f42006-02-28 16:37:25 +0000753- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
754 explicitly relative, using 'from .module import name' to mean 'from the same
755 package as this module is in. Imports without dots still default to the
756 old relative-then-absolute, unless 'from __future__ import
757 absolute_import' is used.
758
Brett Cannona7446e32006-02-27 23:39:10 +0000759- Properly check if 'warnings' raises an exception (usually when a filter set
760 to "error" is triggered) when raising a warning for raising string
761 exceptions.
762
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000763- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000764 The name was removed from Include/code.h.
765
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000766- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000767
Guido van Rossum1968ad32006-02-25 22:38:04 +0000768- Patch 1433928:
769 - The copy module now "copies" function objects (as atomic objects).
770 - dict.__getitem__ now looks for a __missing__ hook before raising
771 KeyError.
772
Tim Peters84ef21c2006-02-28 20:39:06 +0000773- PEP 343: with statement implemented. Needs ``from __future__ import
774 with_statement``. Use of 'with' as a variable will generate a warning.
775 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000776 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000777 The following objects have __context__ methods:
778 - The built-in file type.
779 - The thread.LockType type.
780 - The following types defined by the threading module:
781 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
782 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000783
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000784- Fix the encodings package codec search function to only search
785 inside its own package. Fixes problem reported in patch #1433198.
786
787 Note: Codec packages should implement and register their own
788 codec search function. PEP 100 has the details.
789
Tim Peters9ea89d22006-06-04 03:26:02 +0000790- PEP 353: Using ``Py_ssize_t`` as the index type.
791
792- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
793 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
794 now allow Python to make use of memory blocks exceeding 2**32 bytes for
795 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
796 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000797
Neal Norwitzfc76d632006-01-10 06:03:13 +0000798- Patch #1400181, fix unicode string formatting to not use the locale.
799 This is how string objects work. u'%f' could use , instead of .
800 for the decimal point. Now both strings and unicode always use periods.
801
Neal Norwitz671b9e32006-01-09 07:07:12 +0000802- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
803 configure would break checking curses.h.
804
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000805- Bug #959576: The pwd module is now builtin. This allows Python to be
806 built on UNIX platforms without $HOME set.
807
Neal Norwitzc10978f2005-12-19 06:07:16 +0000808- Bug #1072182, fix some potential problems if characters are signed.
809
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000810- Bug #889500, fix line number on SyntaxWarning for global declarations.
811
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000812- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
813
Neal Norwitze7214a12005-12-18 05:03:17 +0000814- Support for converting hex strings to floats no longer works.
815 This was not portable. float('0x3') now raises a ValueError.
816
Barry Warsaw2a38a862005-12-18 01:27:35 +0000817- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000818 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000819 is now displayed in interactive prompt banner.
820
Georg Brandlfa166682005-12-17 21:45:17 +0000821- Implementation of PEP 341 - Unification of try/except and try/finally.
822 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000823 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000824
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000825- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
826 now encodes backslash correctly.
827
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000828- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
829
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000830- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000831 and long longs.
832
Neal Norwitz67715f02005-11-09 06:59:35 +0000833- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000834 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000835 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000836
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000837- Replaced most Unicode charmap codecs with new ones using the
838 new Unicode translate string feature in the builtin charmap
839 codec; the codecs were created from the mapping tables available
840 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
841 encodings now include a mapping for the Apple logo)
842
Tim Peterse3547fd2005-12-16 23:13:57 +0000843- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000844
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000845- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000846
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000847- A new AST parser implementation was completed. The abstract
848 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000849 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000850
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000851- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000852 The following code now raises a SyntaxError: foo(a = i for i in range(10))
853
Neal Norwitz708e51a2005-10-03 04:48:15 +0000854- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
855
Neal Norwitz11bd1192005-10-03 00:54:56 +0000856- SF Bug #887946: fix segfault when redirecting stdin from a directory.
857 Provide a warning when a directory is passed on the command line.
858
Neal Norwitz40d37812005-10-02 01:48:49 +0000859- Fix segfault with invalid coding.
860
861- SF bug #772896: unknown encoding results in MemoryError.
862
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000863- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000864 supported a __len__() method which evaluated to False when the iterator
865 was empty.
866
Guido van Rossum630db602005-09-20 18:49:54 +0000867- On 64-bit platforms, when __len__() returns a value that cannot be
868 represented as a C int, raise OverflowError.
869
Skip Montanarof8948ca2005-09-19 03:54:46 +0000870- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000871 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000872
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000873- SF bug #893549: parsing keyword arguments was broken with a few format
874 codes.
875
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000876- Changes donated by Elemental Security to make it work on AIX 5.3
877 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
878 bug #105470: test_pwd fails on 64bit system (Opteron).
879
Guido van Rossum539c6622005-09-14 17:49:54 +0000880- Changes donated by Elemental Security to make it work on HP-UX 11 on
881 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
882
Georg Brandl4550b8d2005-08-26 06:43:52 +0000883- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000884 (fixes bug #1119418).
885
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000886- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
887
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000888- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
889 exceptions that cause a function to exit.
890
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000891- The implementation of set() and frozenset() was revised to use its
892 own internal data structure. Memory consumption is reduced by 1/3
893 and there are modest speed-ups as well. The API is unchanged.
894
Tim Petersde7990b2005-07-17 23:45:23 +0000895- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
896
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000897- SF bug #1229429: PyObject_CallMethod failed to decrement some
898 reference counts in some error exit cases.
899
Tim Petersecc6e6a2005-07-10 22:30:55 +0000900- SF bug #1185883: Python's small-object memory allocator took over
901 a block managed by the platform C library whenever a realloc specified
902 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000903 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000904 portable way to copy data from the C-managed block into Python's
905 small-object space without risking a memory fault. Python's small-object
906 realloc now leaves such blocks under the control of the platform C
907 realloc.
908
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000909- SF bug #1232517: An overflow error was not detected properly when
910 attempting to convert a large float to an int in os.utime().

Raymond Hettinger3296e692005-06-29 23:29:56 +0000912- SF bug #1224347: hex longs now print with lowercase letters just
913 like their int counterparts.
914
Michael W. Hudson188d4362005-06-20 16:52:57 +0000915- SF bug #1163563: the original fix for bug #1010677 ("thread Module
916 Breaks PyGILState_Ensure()") broke badly in the case of multiple
917 interpreter states; back out that fix and do a better job (see
918 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
919 for a longer write-up of the problem).
920
Michael W. Hudsondf888462005-06-03 14:41:55 +0000921- SF patch #1180995: marshal now uses a binary format by default when
922 serializing floats.
923
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000924- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
925 the routines that promise to produce IEEE 754 binary representations
926 of floats now simply copy bytes around.
927
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000928- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
929 278.
930
Brett Cannonc3647ac2005-04-26 03:45:26 +0000931- patch #1109424: int, long, float, complex, and unicode now check for the
932 proper magic slot for type conversions when subclassed. Previously the
933 magic slot was ignored during conversion. Semantics now match the way
934 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000935 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000936 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000937 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000938
Barry Warsawc8d907c2005-04-19 23:43:40 +0000939- Descriptors defined in C with a PyGetSetDef structure, where the setter is
940 NULL, now raise an AttributeError when attempting to set or delete the
941 attribute. Previously a TypeError was raised, but this was inconsistent
942 with the equivalent pure-Python implementation.
943
Michael W. Hudson774479c2005-04-18 08:46:17 +0000944- It is now safe to call PyGILState_Release() before
945 PyEval_InitThreads() (note that if there is reason to believe there
946 are multiple threads around you still must call PyEval_InitThreads()
947 before using the Python API; this fix is for extension modules that
948 have no way of knowing if Python is multi-threaded yet).
949
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000950- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
951 disabled caused a crash.
952
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000953- Bug #1165306: instancemethod_new allowed the creation of a method
954 with im_class == im_self == NULL, which caused a crash when called.
955
Tim Petersecc6e6a2005-07-10 22:30:55 +0000956- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000957 fixes the crash seen in bug #1165761
958
Raymond Hettinger96229b12005-03-11 06:49:40 +0000959- Added two new builtins, any() and all().
960
Brett Cannon409d8f22005-03-05 06:47:57 +0000961- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000962 (e.g., ``class C(): pass`` is no longer a syntax error).
963 Patch #1176012 added support to the 'parser' module and 'compiler' package
964 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000965
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000966- Patch #1115086: Support PY_LONGLONG in structmember.
967
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000968- Bug #1155938: new style classes did not check that __init__() was
969 returning None.
970
Tim Petersecc6e6a2005-07-10 22:30:55 +0000971- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000972 ('\') with a specific error message.
973
Martin v. Löwisff232d72005-03-03 09:24:38 +0000974- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
975
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000976- Bug #1124295: the __name__ attribute of file objects was
977 inadvertently made inaccessible in restricted mode.
978
Tim Petersecc6e6a2005-07-10 22:30:55 +0000979- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000980 an ferror() call.
981
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000982- min() and max() now support key= arguments with the same meaning as in
983 list.sort().
984
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000985- The peephole optimizer now performs simple constant folding in expressions:
986 (2+3) --> (5).
987
Raymond Hettingera422c342005-01-11 03:03:27 +0000988- set and frozenset objects can now be marshalled. SF #1098985.
989
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000990- Bug #1077106: Poor argument checking could cause memory corruption
991 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000992
Jeremy Hyltonab630502005-02-04 18:44:06 +0000993- The parser did not complain about future statements in illegal
994 positions. It once again reports a syntax error if a future
995 statement occurs after anything other than a doc string.
996
Neil Schemenauercf52c072005-08-12 17:34:58 +0000997- Change the %s format specifier for str objects so that it returns a
998 unicode instance if the argument is not an instance of basestring and
999 calling __str__ on the argument returns a unicode instance.
1000
Tim Petersf4e69282006-02-27 17:15:31 +00001001- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1002 current thread state when the auto-GIL-state machinery knows about
1003 it (since the thread state is being deleted, continuing to remember it
1004 can't help, but can hurt if another thread happens to get created with
1005 the same thread id).
1006
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001007Extension Modules

1032
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001033- The unicodedata module was updated to the 4.1 version of the Unicode

1035 for applications that require this specific version (such as IDNA).
1036
Neal Norwitzb62c4332006-03-04 18:35:47 +00001037- The timing module is no longer built by default. It was deprecated

1060 are reported, the limit on path name lengths is removed, and stat reports
1061 WindowsError now (instead of OSError).
1062

1196
Nick Coghlan43832302006-04-23 17:04:07 +00001197- PEP 338: new module runpy defines a run_module function to support
1198 executing modules which provide access to source code or a code object
1199 via the PEP 302 import mechanisms.
1200
Anthony Baxter93f5b932006-04-03 08:05:07 +00001201- The email module's parsedate_tz function now sets the daylight savings

1209 in attribute values.
1210
Anthony Baxterc51ee692006-04-01 00:57:31 +00001211- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001212 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001213 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001214 module will not be built.
1215
Tim Petersc17976e2006-04-01 00:26:53 +00001216- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1217 aren't officially supported here, and trying to use them will probably
1218 raise an exception some day. But dicts have been allowed, and "mostly
1219 worked", so support for them won't go away without warning.
1220
Georg Brandl338ef7d2006-03-31 18:42:16 +00001221- Bug #1445068: getpass.getpass() can now be given an explicit stream

1233 to make it easier to monitor when daemon threads have completed
1234 processing all enqueued tasks. Patch #1455676.
1235
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001236- popen2.Popen objects now preserve the command in a .cmd attribute.

1239
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001240- email 4.0 package now integrated. This is largely the same as the email 3.0
1241 package that was included in Python 2.3, except that PEP 8 module names are
1242 now used (e.g. mail.message instead of email.Message). The MIME classes
1243 have been moved to a subpackage (e.g. email.mime.text instead of
1244 email.MIMEText). The old names are still supported for now. Several
1245 deprecated Message methods have been removed and lots of bugs have been
1246 fixed. More details can be found in the email package documentation.
1247
Walter Dörwald40108c92006-03-27 08:15:44 +00001248- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1249 (a subclass of tuple) that provides incremental decoders and encoders
1250 (a way to use stateful codecs without the stream API). Python functions
1251 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1252 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1253 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001254
Walter Dörwald067db482006-03-15 22:17:27 +00001255- Patch #1359365: Calling next() on a closed StringIO.String object raises
1256 a ValueError instead of a StopIteration now (like file and cString.String do).
1257 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1258 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001259

1333 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1334 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1335 Ronald L. Rivest offered this advice for Python:
1336
1337 "The consensus of researchers in this area (at least as
1338 expressed at the NIST Hash Function Workshop 10/31/05),
1339 is that SHA-256 is a good choice for the time being, but
1340 that research should continue, and other alternatives may
1341 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001342
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001343- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl268e61c2005-06-03 14:28:50 +00001445- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1446 component of the path.
1447
Skip Montanaro174dd222005-05-14 20:54:16 +00001448- Patch #1120353: The xmlrpclib module provides better, more transparent,
1449 support for datetime.{datetime,date,time} objects. With use_datetime set
1450 to True, applications shouldn't have to fiddle with the DateTime wrapper
1451 class at all.
1452
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001453- distutils.commands.upload was added to support uploading distribution
1454 files to PyPI.
1455
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001456- distutils.commands.register now encodes the data as UTF-8 before posting
1457 them to PyPI.
1458
Raymond Hettinger267b8682005-03-27 10:47:39 +00001459- decimal operator and comparison methods now return NotImplemented
1460 instead of raising a TypeError when interacting with other types. This
1461 allows other classes to implement __radd__ style methods and have them
1462 work as expected.
1463
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001464- Bug #1163325: Decimal infinities failed to hash. Attempting to
1465 hash a NaN raised an InvalidOperation instead of a TypeError.
1466
Tim Petersecc6e6a2005-07-10 22:30:55 +00001467- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001468 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1469
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001470- Patch #1043890: Add extractall method to tarfile.
1471
Martin v. Löwisc72dd382005-03-04 13:50:17 +00001472- Patch #1075887: Don't require MSVC in distutils if there is nothing
1473 to build.
1474
Martin v. Löwis637431b2005-03-03 23:12:42 +00001475- Patch #1103407: Properly deal with tarfile iterators when untarring
1476 symbolic links on Windows.
1477
Tim Petersecc6e6a2005-07-10 22:30:55 +00001478- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001479 profile.py if available.
1480
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001481- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1482
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001483- Patch #1117454: Remove code to special-case cookies without values
1484 in LWPCookieJar.
1485
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001486- Patch #1117339: Add cookielib special name tests.
1487
Martin v. Löwise869eb12005-03-03 09:46:07 +00001488- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1489
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001490- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1491
Martin v. Löwisdf241532005-03-03 08:17:42 +00001492- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1493
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001494- Patch #1104111: Alter setup.py --help and --help-commands.
1495
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001496- Patch #1121234: Properly cleanup _exit and tkerror commands.
1497
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001498- Patch #1049151: xdrlib now unpacks booleans as True or False.
1499
Raymond Hettingerbab41432005-02-05 01:31:19 +00001500- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1501
Guido van Rossumd0641422005-02-03 15:01:24 +00001502- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1503 disables recursive traversal through instance attributes, which can
1504 be exploited in various ways.
1505
Tim Peterse3547fd2005-12-16 23:13:57 +00001506- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001507 flags on the HTTP listening socket.
1508
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001509- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1510 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1511
Tim Peterse3547fd2005-12-16 23:13:57 +00001512- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001513 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1514
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001515- Bug #1110478: Revert os.environ.update to do putenv again.
1516
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001517- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1518
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001519- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1520
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001521- Enhancements to the csv module:
1522
1523 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001524 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001525 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001526 + Dialect parameter parsing has been re-implemented to improve error
1527 reporting.
1528 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1529 dictates.
1530 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001531 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001532 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001533 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1534 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001535 + reader now allows \r characters to be quoted (previously it only allowed
1536 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001537 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001538 + Dialect classes passed to the module are no longer instantiated by
1539 the module before being parsed (the former validation scheme required
1540 this, but the mechanism was unreliable).
1541 + The dialect registry now contains instances of the internal
1542 C-coded dialect type, rather than references to python objects.
1543 + the internal c-coded dialect type is now immutable.
1544 + register_dialect now accepts the same keyword dialect specifications
1545 as the reader and writer, allowing the user to register dialects
1546 without first creating a dialect class.
1547 + a configurable limit to the size of parsed fields has been added -
1548 previously, an unmatched quote character could result in the entire
1549 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001550 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001551 the parser field size limit (returning the former limit). The initial
1552 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001553 + A line_num attribute has been added to the reader object, which tracks
1554 the number of lines read from the source iterator. This is not
1555 the same as the number of records returned, as records can span
1556 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001557 + reader and writer objects were not being registered with the cyclic-GC.
1558 This has been fixed.
1559
Brett Cannone6539c42005-01-08 02:43:53 +00001560- _DummyThread objects in the threading module now delete self.__block that is
1561 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1562 lock primitives tend to be limited in number and thus should not be wasted on
1563 a _DummyThread object. Fixes bug #1089632.
1564
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001565- The imghdr module now detects Exif files.
1566
Raymond Hettinger6065d322004-12-20 23:51:53 +00001567- StringIO.truncate() now correctly adjusts the size attribute.
1568 (Bug #951915).
1569
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001570- locale.py now uses an updated locale alias table (built using
1571 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1572 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001573 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001574
Raymond Hettinger3557f422004-12-07 12:02:02 +00001575- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1576
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001577- the pickle module no longer accepts the deprecated None option in the
1578 args tuple returned by __reduce__().
1579
Brett Cannon84667c02004-12-07 03:25:18 +00001580- optparse now optionally imports gettext. This allows its use in setup.py.
1581
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001582- the pickle module no longer uses the deprecated bin parameter.
1583
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001584- the shelve module no longer uses the deprecated binary parameter.
1585
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001586- the pstats module no longer uses the deprecated ignore() method.
1587
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001588- the filecmp module no longer uses the deprecated use_statcache argument.
1589
Raymond Hettinger664347b2004-12-04 21:21:53 +00001590- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1591 extended or overridden by subclasses. Formerly, the subclassed method would
1592 be ignored by the rest of the module. (Bug #1078905).
1593
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001594- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001595 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001596
Walter Dörwald36733692004-12-22 12:50:50 +00001597- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1598 once when a size argument is given. This prevents a buffer overflow in the
1599 tokenizer with very long source lines.
1600
Barry Warsaw538561e2006-01-01 21:48:54 +00001601- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1602 immediately after creating the object, without any intervening
1603 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001604
Skip Montanaro05885812005-01-16 20:48:27 +00001605- The reconvert.quote function can now emit triple-quoted strings. The
1606 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001607
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001608- ``UserString.MutableString`` now supports negative indices in
1609 ``__setitem__`` and ``__delitem__``
1610
Greg Ward40407942005-03-05 02:53:17 +00001611- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1612 correctly.
1613
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001614- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1615 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1616 character even if the user has passed a size parameter to get a proper
1617 line ending. Remove the special handling of a "\r\n" that has been split
1618 between two lines.
1619
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001620- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1621 about illegal code points. The codec now supports PEP 293 style error
1622 handlers.
1623
Walter Dörwald78a78b02005-09-01 12:04:29 +00001624- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001625 from the input stream, so that the output is a byte string in the correct
1626 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001627
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001628- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1629 considering it exactly like a '*'.
1630
Walter Dörwald007f8df2005-10-09 19:42:27 +00001631- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1632 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001633
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001634- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1635
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001636- Patch #1413711: Certain patterns of differences were making difflib
1637 touch the recursion limit.
1638
Walter Dörwald58917a62006-03-31 15:26:22 +00001639- Bug #947906: An object oriented interface has been added to the calendar
1640 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001641 called as a script (e.g. via ``python -mcalendar``). Localized month and
1642 weekday names can be ouput (even if an exotic encoding is used) using
1643 special classes that use unicode.

1646-----
1647
Neal Norwitz602d3392006-03-31 08:21:40 +00001648- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1649 by using -mieee gcc option.
1650
Martin v. Löwis86d66262006-02-17 08:40:11 +00001651- Patch #1432345: Make python compile on DragonFly.
1652
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001653- Build support for Win64-AMD64 was added.
1654
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001655- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1656
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001657- Patch #881820: look for openpty and forkpty also in libbsd.
1658
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001659- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1660 The zlib module is now builtin on Windows.
1661
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001662- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1663
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001664- Bug #1189330: configure did not correctly determine the necessary
1665 value of LINKCC if python was built with GCC 4.0.
1666
Trent Mick8321b422005-07-26 02:29:21 +00001667- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1668 vulnerability in zlib 1.2.1 and 1.2.2.
1669
Brett Cannon08cd5982005-04-24 22:26:38 +00001670- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1671 flags that change binary compatibility. Changes were also made to
1672 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001673 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001674
Bob Ippolitoed233462005-03-29 13:47:59 +00001675- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1676 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1677 no longer exists). This configure patch makes things right.
1678
Martin v. Löwise2713be2005-03-08 15:03:08 +00001679- Bug #1158607: Build with --disable-unicode again.
1680
Brett Cannon46d96232005-02-16 00:07:19 +00001681- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1682 defined. Discovered as a result of not being able to build on OS X.
1683
Brett Cannon516592f2004-12-07 00:42:59 +00001684- setup.py now uses the directories specified in LDFLAGS using the -L option
1685 and in CPPFLAGS using the -I option for adding library and include
1686 directories, respectively, for compiling extension modules against. This has
1687 led to the core being compiled using the values in CPPFLAGS. It also removes
1688 the need for the special-casing of both DarwinPorts and Fink for darwin since
1689 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1690 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1691 Fink, ``-I/opt/local/include`` for DarwinPorts).
1692
Brett Cannon43802422005-02-10 20:48:03 +00001693- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1694 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1695 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1696 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001698C API
1699-----
1700
Tim Petersc9d78aa2006-03-26 23:27:58 +00001701- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1702 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1703 is obtained via the ``PyObject_`` family, it must be released via the
1704 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1705 always been officially true, but when Python's small-object allocator was
1706 introduced, an attempt was made to cater to a few extension modules
1707 discovered at the time that obtained memory via ``PyObject_New`` but
1708 released it via ``PyMem_DEL``. It's years later, and if such code still
1709 exists it will fail now (probably with segfaults, but calling wrong
