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.

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

171-----
172
Tim Peters32a83612006-07-10 21:08:24 +0000173- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000174 Previously, the slight difference could cause compilation errors of the
175 'zlib' module on systems with more than one version of zlib.
176
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000177- The MSI compileall step was fixed to also support a TARGETDIR
178 with spaces in it.
179
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000180- Bug #1517388: sqlite3.dll is now installed on Windows independent
181 of Tcl/Tk.
182
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000183- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000184 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000185
Neal Norwitzb15ac312006-06-29 04:10:08 +0000186Tests
187-----
188
189- Call os.waitpid() at the end of tests that spawn child processes in order
190 to minimize resources (zombies).
191
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000192Documentation
193-------------
194
Nick Coghlan2d792252006-07-06 13:47:18 +0000195- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
196 documentation for the warnings module.
197
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000198- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000204
Anthony Baxterd1136802006-06-19 12:04:15 +0000205*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000206
207Core and builtins
208-----------------
209
Georg Brandla56b9152006-06-19 06:35:54 +0000210- Patch #1507676: Error messages returned by invalid abstract object operations
211 (such as iterating over an integer) have been improved and now include the
212 type of the offending object to help with debugging.
213
Brett Cannonea3912b2006-06-13 21:46:41 +0000214- Bug #992017: A classic class that defined a __coerce__() method that returned
215 its arguments swapped would infinitely recurse and segfault the interpreter.
216
Neal Norwitz909eb122006-06-12 02:13:21 +0000217- Fix the socket tests so they can be run concurrently.
218
Neal Norwitzb9845e72006-06-12 02:11:18 +0000219- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000220 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000221
Brett Cannon22565aa2006-06-09 22:31:23 +0000222- Bug #532646: object.__call__() will continue looking for the __call__
223 attribute on objects until one without one is found. This leads to recursion
224 when you take a class and set its __call__ attribute to an instance of the
225 class. Originally fixed for classic classes, but this fix is for new-style.
226 Removes the infinite_rec_3 crasher.
227
Georg Brandl24250812006-06-09 18:45:48 +0000228- The string and unicode methods startswith() and endswith() now accept
229 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
230
Brett Cannonde3b0522006-06-08 17:00:45 +0000231- Buffer objects, at the C level, never used the char buffer
232 implementation even when the char buffer for the wrapped object was
233 explicitly requested (originally returned the read or write buffer).
234 Now a TypeError is raised if the char buffer is not present but is
235 requested.
236
Georg Brandlddbaa662006-06-04 21:56:52 +0000237- Patch #1346214: Statements like "if 0: suite" are now again optimized
238 away like they were in Python 2.4.
239
Georg Brandlb7c8f542006-05-27 12:30:25 +0000240- Builtin exceptions are now full-blown new-style classes instead of
241 instances pretending to be classes, which speeds up exception handling
242 by about 80% in comparison to 2.5a2.
243
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000244- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
245 Unicode 4.1.
246
Georg Brandlf4ef1162006-05-26 18:03:31 +0000247- Patch #921466: sys.path_importer_cache is now used to cache valid and
248 invalid file paths for the built-in import machinery which leads to
249 fewer open calls on startup.
250
Tim Peters696cf432006-05-24 21:10:40 +0000251- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
252 of-2 bases. The largest speedup is for inputs with about 1000 decimal
253 digits. Conversion from non-power-of-2 bases remains quadratic-time in
254 the number of input digits (it was and remains linear-time for bases
255 2, 4, 8, 16 and 32).
256
Tim Petersb713ec22006-05-23 18:45:30 +0000257- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
258 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
259 an integer close to ``sys.maxint``. This was repaired by patch
260 #1335972, which also gives a nice speedup.
261
Richard Jonescebbefc2006-05-23 18:28:17 +0000262- Patch #1337051: reduced size of frame objects.
263
264- PyErr_NewException now accepts a tuple of base classes as its
265 "base" parameter.
266
Richard Jones7c88dcc2006-05-23 10:37:38 +0000267- Patch #876206: function call speedup by retaining allocated frame
268 objects.
269
Georg Brandl7b90e162006-05-18 07:01:27 +0000270- Bug #1462152: file() now checks more thoroughly for invalid mode
271 strings and removes a possible "U" before passing the mode to the
272 C library function.
273
Neal Norwitz1004a532006-05-15 07:17:23 +0000274- Patch #1488312, Fix memory alignment problem on SPARC in unicode
275
Neal Norwitz373f0a72006-05-15 07:04:36 +0000276- Bug #1487966: Fix SystemError with conditional expression in assignment
277
Martin v. Löwis879768d2006-05-11 13:28:43 +0000278- WindowsError now has two error code attributes: errno, which carries
279 the error values from errno.h, and winerror, which carries the error
280 values from winerror.h. Previous versions put the winerror.h values
281 (from GetLastError()) into the errno attribute.
282
Martin v. Löwis77736712006-05-04 05:51:03 +0000283- Patch #1475845: Raise IndentationError for unexpected indent.
284
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000285- Patch #1479181: split open() and file() from being aliases for each other.
286
Tim Peters44bd9862006-06-01 13:49:23 +0000287- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
288 methods were always silently ignored by dictionaries when comparing keys.
289 They are now passed through (except when using the C API function
290 ``PyDict_GetItem()``, whose semantics did not change).
291
292- Bug #1456209: In some obscure cases it was possible for a class with a
293 custom ``__eq__()`` method to confuse dict internals when class instances
294 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
295 No, you don't have any code that did this ;-)

301
302- Patch #1462338: Upgrade pyexpat to expat 2.0.0
303
Brett Cannon6ee7d012006-06-08 16:23:04 +0000304- Change binascii.hexlify to accept a read-only buffer instead of only a char
305 buffer and actually follow its documentation.
306

308
Nick Coghlanc649ec52006-05-29 12:43:05 +0000309- Patch #1478788 (modified version): The functional extension module has
310 been renamed to _functools and a functools Python wrapper module added.
311 This provides a home for additional function related utilities that are
312 not specifically about functional programming. See PEP 309.
313
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000314- Patch #1493701: performance enhancements for struct module.

317
Georg Brandl8d3342b2006-05-16 07:38:27 +0000318- Patch #1435422: zlib's compress and decompress objects now have a
319 copy() method.
320
Andrew MacIntyre92913322006-06-13 15:04:24 +0000321- Patch #1454481: thread stack size is now tunable at runtime for thread
322 enabled builds on Windows and systems with Posix threads support.
323
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000324- On Win32, os.listdir now supports arbitrarily-long Unicode path names
325 (up to the system limit of 32K characters).
326
327- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
328 As a result, these functions now raise WindowsError instead of OSError.
329
Tim Peters7a822da2006-05-25 21:50:17 +0000330- ``time.clock()`` on Win64 should use the high-performance Windows
331 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
332 Windows platforms).
333
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000334- Calling Tk_Init twice is refused if the first call failed as that
335 may deadlock.
336
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000337- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
338 accept it without potentially using an uninitialized pointer.
339
340- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
341 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
342 patch numbers 1494885 and 1494902]

Gregory P. Smith372b5832006-06-05 18:48:21 +0000344- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000345 [pybsddb project SF patch number 1466734]
346
Gregory P. Smith372b5832006-06-05 18:48:21 +0000347- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
348 parameter is supplied. [SF pybsddb bug #1477863]
349
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000350- bsddb: the __len__ method of a DB object has been fixed to return correct
351 results. It could previously incorrectly return 0 in some cases.
352 Fixes SF bug 1493322 (pybsddb bug 1184012).
353
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000354- bsddb: the bsddb.dbtables Modify method now raises the proper error and
355 aborts the db transaction safely when a modifier callback fails.
356 Fixes SF python patch/bug #1408584.
357
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000358- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000359 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000360 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
361 database calls that would previously deadlock. [SF python bug #775414]

389
Martin v. Löwisd8251432006-06-14 05:21:04 +0000390- Patch #1455898: The MBCS codec now supports the incremental mode for
391 double-byte encodings.
392
Tim Peters43898b42006-06-14 04:09:25 +0000393- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
394 guarantee that adjacent triples in the return list always describe
395 non-adjacent blocks. Previously, a pair of matching blocks could end
396 up being described by multiple adjacent triples that formed a partition
397 of the matching pair.
398
Greg Ward0e0c9f42006-06-11 16:24:11 +0000399- Bug #1498146: fix optparse to handle Unicode strings in option help,
400 description, and epilog.
401
Greg Wardd1c797e2006-06-11 14:42:41 +0000402- Bug #1366250: minor optparse documentation error.

405 clarify docs.
406
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000407- The wsgiref package has been added to the standard library.
408
Nick Coghlan676725d2006-06-08 13:54:49 +0000409- The functions update_wrapper() and wraps() have been added to the functools
410 module. These make it easier to copy relevant metadata from the original
411 function when writing wrapper functions.
412
Tim Petersd6a9eef2006-06-05 01:48:21 +0000413- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
414 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000415
Martin v. Löwis3f767792006-06-04 19:36:28 +0000416- Patch #1359618: Speed up charmap encoder by using a trie structure
417 for lookup.
418
Tim Petersd609b1a2006-06-02 23:22:51 +0000419- The functions in the ``pprint`` module now sort dictionaries by key
420 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
421 if and only if its display required more than one line, although that
422 wasn't documented. The new behavior increases predictability; e.g.,
423 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
424
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000425- Patch #1497027: try HTTP digest auth before basic auth in urllib2

432
Bob Ippolito7298f272006-05-23 18:43:47 +0000433- Patch #1281707: speed up gzip.readline.
434
Georg Brandlb89316f2006-05-17 15:51:16 +0000435- Patch #1180296: Two new functions were added to the locale module:
436 format_string() to get the effect of "format % items" but locale-aware,
437 and currency() to format a monetary number with currency sign.
438
Georg Brandle3a25832006-05-17 14:56:04 +0000439- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
440 and several features added, such as speed and geometry control.

443 tarfiles.
444
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000445- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
446 stdout arguments, making it possible to redirect input and output
447 for remote debugging.
448
449- Patch #1484695: Update the tarfile module to version 0.8. This fixes
450 a couple of issues, notably handling of long file names using the
451 GNU LONGNAME extension.
452
453- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
454 new flag when ``name`` is already the name of an option flag.
455
456- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
457 package.

499
500Core and builtins
501-----------------
502
Thomas Heller1b046642006-04-18 18:51:06 +0000503- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
504 by converting these apis from macros into exported functions again:
505
506 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
507 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
508 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
509 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
510 PyRun_String Py_CompileString
511
Martin v. Löwis45294a92006-04-18 06:24:08 +0000512- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
513
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000514- All uses of PyStructSequence_InitType have been changed to initialize
515 the type objects only once, even if the interpreter is initialized
516 multiple times.
517
Neal Norwitz61546162006-04-14 05:20:28 +0000518- Bug #1454485, array.array('u') could crash the interpreter. This was
519 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
520 to unicode when it didn't make sense. 'u#' now requires a unicode string.
521
522- Py_UNICODE is unsigned. It was always documented as unsigned, but
523 due to a bug had a signed value in previous versions.
524
Tim Peters3a5e8b12006-04-11 01:44:07 +0000525- Patch #837242: ``id()`` of any Python object always gives a positive
526 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
527 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000528 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000529 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000530
Tim Peters3a5e8b12006-04-11 01:44:07 +0000531 def __hash__(self):
532 return id(self) # WRONG
533
534 because a hash result must be a (short) Python int but it was always
535 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000536 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000537 was always usable as a hash value before this patch. That's no longer
538 necessarily so.
539
540- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000541 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000542 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000543 #1454844)
544
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000545- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
546 involving generators that have paused outside of any ``try`` or ``with``
547 blocks. (In 2.5a1, a paused generator that was part of a reference
548 cycle could not be garbage collected, regardless of whether it was
549 paused in a ``try`` or ``with`` block.)

575-------
576
Tim Peters711bf302006-04-25 03:31:36 +0000577- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
578 a doctest to be skipped (the code is not run, and the expected output
579 or exception is ignored).
580
Nick Coghlanda2268f2006-04-24 04:37:15 +0000581- Fixed contextlib.nested to cope with exceptions being raised and
582 caught inside exit handlers.

585 hex, octal, or binary; add ``append_const`` action; keep going if
586 gettext cannot be imported; added ``OptionParser.destroy()`` method;
587 added ``epilog`` for better help generation).
588
Tim Peters21fbd572006-04-21 21:18:10 +0000589- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
590 called from a thread spawned as a side effect of importing a module.
591
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000592- The pydoc module now supports documenting packages contained in
593 .zip or .egg files.
594
595- The pkgutil module now has several new utility functions, such
596 as ``walk_packages()`` to support working with packages that are either
597 in the filesystem or zip files.
598
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000599- The mailbox module can now modify and delete messages from
600 mailboxes, in addition to simply reading them. Thanks to Gregory
601 K. Johnson for writing the code, and to the 2005 Google Summer of
602 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000603
Tim Petersc7605f22006-04-17 21:12:33 +0000604- The ``__del__`` method of class ``local`` in module ``_threading_local``
605 returned before accomplishing any of its intended cleanup.
606

Anthony Baxtere29002c2006-04-12 12:07:31 +0000613- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
614 Windows. Bug #1469163.
615
Phillip J. Eby47032112006-04-11 01:07:43 +0000616- The warnings, linecache, inspect, traceback, site, and doctest modules
617 were updated to work correctly with modules imported from zipfiles or

Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000638- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000639
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000640- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
641 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000642 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000643 CXX from --with-cxx-main, see description in README.
644
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000645- Patch #1429775: Link extension modules with the shared libpython.
646
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000647- Fixed a libffi build problem on MIPS systems.
648
Tim Peters8931ff12006-05-13 23:28:20 +0000649- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
650 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
651 and "%zu" for unsigned integers of type ``size_t``.
652
Anthony Baxter51bcb682006-04-05 14:51:42 +0000653Tests
654-----
655
Nick Coghlanda2268f2006-04-24 04:37:15 +0000656- test_contextlib now checks contextlib.nested can cope with exceptions
657 being raised and caught inside exit handlers.
658
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000659- test_cmd_line now checks operation of the -m and -c command switches
660
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000661- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
662 it separately and by hand. It also wasn't cleaning up its changes to
663 the current Decimal context.
664
Thomas Woutersabd08882006-04-26 15:53:30 +0000665- regrtest.py now has a -M option to run tests that test the new limits of
666 containers, on 64-bit architectures. Running these tests is only sensible
667 on 64-bit machines with more than two gigabytes of memory. The argument
668 passed is the maximum amount of memory for the tests to use.

672
673- Added the Python benchmark suite pybench to the Tools/ directory;
674 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000676Documentation
677-------------
678
Tim Petersb06d28c2006-05-12 01:57:59 +0000679- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
680
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000681- PEP 343: Added Context Types section to the library reference
682 and attempted to bring other PEP 343 related documentation into
683 line with the implementation and/or python-dev discussions.
684
Tim Peters8dc73d22006-04-24 02:03:16 +0000685- Bug #1337990: clarified that ``doctest`` does not support examples
686 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000689What's New in Python 2.5 alpha 1?
690=================================
691
Anthony Baxterebed3f62006-04-03 15:03:44 +0000692*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000693
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000694Core and builtins
695-----------------
696
Nick Coghlan43832302006-04-23 17:04:07 +0000697- PEP 338: -m command line switch now delegates to runpy.run_module
698 allowing it to support modules in packages and zipfiles
699
Martin v. Löwisc661b882006-04-20 04:54:23 +0000700- On Windows, .DLL is not an accepted file name extension for
701 extension modules anymore; extensions are only found if they
702 end in .PYD.
703
Martin v. Löwisea62d252006-04-03 10:56:49 +0000704- Bug #1421664: sys.stderr.encoding is now set to the same value as
705 sys.stdout.encoding.
706
Neal Norwitz92e212f2006-04-03 04:48:37 +0000707- __import__ accepts keyword arguments.
708
Georg Brandlccadf842006-03-31 18:54:53 +0000709- Patch #1460496: round() now accepts keyword arguments.
710
Anthony Baxter262c00a2006-03-30 10:53:17 +0000711- Fixed bug #1459029 - unicode reprs were double-escaped.
712
Hye-Shik Changd478f342006-03-23 12:32:36 +0000713- Patch #1396919: The system scope threads are reenabled on FreeBSD
714 5.4 and later versions.
715
Neal Norwitze98ccf62006-03-23 05:39:47 +0000716- Bug #1115379: Compiling a Unicode string with an encoding declaration
717 now gives a SyntaxError.
718
Georg Brandlabd1ff82006-03-18 07:59:59 +0000719- Previously, Python code had no easy way to access the contents of a
720 cell object. Now, a ``cell_contents`` attribute has been added
721 (closes patch #1170323).
722
Tim Peterscf79aac2006-03-16 01:14:46 +0000723- Patch #1123430: Python's small-object allocator now returns an arena to
724 the system ``free()`` when all memory within an arena becomes unused
725 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
726 freed. Some applications will see a drop in virtual memory size now,
727 especially long-running applications that, from time to time, temporarily
728 use a large number of small objects. Note that when Python returns an
729 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000730 platform C library will in turn return that memory to the operating system.
731 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000732 appears to be effective at least on Microsoft C and gcc-based systems.
733 Thanks to Evan Jones for hard work and patience.
734
Georg Brandl533ff6f2006-03-08 18:09:27 +0000735- Patch #1434038: property() now uses the getter's docstring if there is
736 no "doc" argument given. This makes it possible to legitimately use
737 property() as a decorator to produce a read-only property.
738
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000739- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
740 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
741 of requiring an int or long in slicing and a few other contexts, enabling
742 other objects (e.g. Numeric Python's integers) to be used as slice indices.
743
Neal Norwitz995acdf2006-03-07 05:01:00 +0000744- Fixed various bugs reported by Coverity's Prevent tool.
745
Brett Cannonbf364092006-03-01 04:25:17 +0000746- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
747 new exception base class, BaseException, which has a new message attribute.
748 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
749 Raising a string exception now raises a DeprecationWarning.
750
Thomas Woutersfb609f42006-02-28 16:37:25 +0000751- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
752 explicitly relative, using 'from .module import name' to mean 'from the same
753 package as this module is in. Imports without dots still default to the
754 old relative-then-absolute, unless 'from __future__ import
755 absolute_import' is used.
756
Brett Cannona7446e32006-02-27 23:39:10 +0000757- Properly check if 'warnings' raises an exception (usually when a filter set
758 to "error" is triggered) when raising a warning for raising string
759 exceptions.
760
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000761- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000762 The name was removed from Include/code.h.
763
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000764- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000765
Guido van Rossum1968ad32006-02-25 22:38:04 +0000766- Patch 1433928:
767 - The copy module now "copies" function objects (as atomic objects).
768 - dict.__getitem__ now looks for a __missing__ hook before raising
769 KeyError.
770
Tim Peters84ef21c2006-02-28 20:39:06 +0000771- PEP 343: with statement implemented. Needs ``from __future__ import
772 with_statement``. Use of 'with' as a variable will generate a warning.
773 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000774 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000775 The following objects have __context__ methods:
776 - The built-in file type.
777 - The thread.LockType type.
778 - The following types defined by the threading module:
779 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
780 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000781
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000782- Fix the encodings package codec search function to only search
783 inside its own package. Fixes problem reported in patch #1433198.
784
785 Note: Codec packages should implement and register their own
786 codec search function. PEP 100 has the details.
787
Tim Peters9ea89d22006-06-04 03:26:02 +0000788- PEP 353: Using ``Py_ssize_t`` as the index type.
789
790- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
791 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
792 now allow Python to make use of memory blocks exceeding 2**32 bytes for
793 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
794 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000795
Neal Norwitzfc76d632006-01-10 06:03:13 +0000796- Patch #1400181, fix unicode string formatting to not use the locale.
797 This is how string objects work. u'%f' could use , instead of .
798 for the decimal point. Now both strings and unicode always use periods.
799
Neal Norwitz671b9e32006-01-09 07:07:12 +0000800- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
801 configure would break checking curses.h.
802
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000803- Bug #959576: The pwd module is now builtin. This allows Python to be
804 built on UNIX platforms without $HOME set.
805
Neal Norwitzc10978f2005-12-19 06:07:16 +0000806- Bug #1072182, fix some potential problems if characters are signed.
807
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000808- Bug #889500, fix line number on SyntaxWarning for global declarations.
809
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000810- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
811
Neal Norwitze7214a12005-12-18 05:03:17 +0000812- Support for converting hex strings to floats no longer works.
813 This was not portable. float('0x3') now raises a ValueError.
814
Barry Warsaw2a38a862005-12-18 01:27:35 +0000815- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000816 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000817 is now displayed in interactive prompt banner.
818
Georg Brandlfa166682005-12-17 21:45:17 +0000819- Implementation of PEP 341 - Unification of try/except and try/finally.
820 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000821 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000822
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000823- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
824 now encodes backslash correctly.
825
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000826- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
827
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000828- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000829 and long longs.
830
Neal Norwitz67715f02005-11-09 06:59:35 +0000831- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000832 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000833 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000834
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000835- Replaced most Unicode charmap codecs with new ones using the
836 new Unicode translate string feature in the builtin charmap
837 codec; the codecs were created from the mapping tables available
838 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
839 encodings now include a mapping for the Apple logo)
840
Tim Peterse3547fd2005-12-16 23:13:57 +0000841- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000842
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000843- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000844
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000845- A new AST parser implementation was completed. The abstract
846 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000847 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000848
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000849- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000850 The following code now raises a SyntaxError: foo(a = i for i in range(10))
851
Neal Norwitz708e51a2005-10-03 04:48:15 +0000852- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
853
Neal Norwitz11bd1192005-10-03 00:54:56 +0000854- SF Bug #887946: fix segfault when redirecting stdin from a directory.
855 Provide a warning when a directory is passed on the command line.
856
Neal Norwitz40d37812005-10-02 01:48:49 +0000857- Fix segfault with invalid coding.
858
859- SF bug #772896: unknown encoding results in MemoryError.
860
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000861- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000862 supported a __len__() method which evaluated to False when the iterator
863 was empty.
864
Guido van Rossum630db602005-09-20 18:49:54 +0000865- On 64-bit platforms, when __len__() returns a value that cannot be
866 represented as a C int, raise OverflowError.
867
Skip Montanarof8948ca2005-09-19 03:54:46 +0000868- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000869 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000870
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000871- SF bug #893549: parsing keyword arguments was broken with a few format
872 codes.
873
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000874- Changes donated by Elemental Security to make it work on AIX 5.3
875 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
876 bug #105470: test_pwd fails on 64bit system (Opteron).
877
Guido van Rossum539c6622005-09-14 17:49:54 +0000878- Changes donated by Elemental Security to make it work on HP-UX 11 on
879 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
880
Georg Brandl4550b8d2005-08-26 06:43:52 +0000881- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000882 (fixes bug #1119418).
883
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000884- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
885
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000886- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
887 exceptions that cause a function to exit.
888
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000889- The implementation of set() and frozenset() was revised to use its
890 own internal data structure. Memory consumption is reduced by 1/3
891 and there are modest speed-ups as well. The API is unchanged.
892
Tim Petersde7990b2005-07-17 23:45:23 +0000893- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
894
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000895- SF bug #1229429: PyObject_CallMethod failed to decrement some
896 reference counts in some error exit cases.
897
Tim Petersecc6e6a2005-07-10 22:30:55 +0000898- SF bug #1185883: Python's small-object memory allocator took over
899 a block managed by the platform C library whenever a realloc specified
900 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000901 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000902 portable way to copy data from the C-managed block into Python's
903 small-object space without risking a memory fault. Python's small-object
904 realloc now leaves such blocks under the control of the platform C
905 realloc.
906
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000907- SF bug #1232517: An overflow error was not detected properly when
908 attempting to convert a large float to an int in os.utime().
909
Raymond Hettinger3296e692005-06-29 23:29:56 +0000910- SF bug #1224347: hex longs now print with lowercase letters just
911 like their int counterparts.
912
Michael W. Hudson188d4362005-06-20 16:52:57 +0000913- SF bug #1163563: the original fix for bug #1010677 ("thread Module
914 Breaks PyGILState_Ensure()") broke badly in the case of multiple
915 interpreter states; back out that fix and do a better job (see
916 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
917 for a longer write-up of the problem).
918
Michael W. Hudsondf888462005-06-03 14:41:55 +0000919- SF patch #1180995: marshal now uses a binary format by default when
920 serializing floats.
921
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000922- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
923 the routines that promise to produce IEEE 754 binary representations
924 of floats now simply copy bytes around.
925
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000926- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
927 278.
928
Brett Cannonc3647ac2005-04-26 03:45:26 +0000929- patch #1109424: int, long, float, complex, and unicode now check for the
930 proper magic slot for type conversions when subclassed. Previously the
931 magic slot was ignored during conversion. Semantics now match the way
932 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000933 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000934 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000935 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000936
Barry Warsawc8d907c2005-04-19 23:43:40 +0000937- Descriptors defined in C with a PyGetSetDef structure, where the setter is
938 NULL, now raise an AttributeError when attempting to set or delete the
939 attribute. Previously a TypeError was raised, but this was inconsistent
940 with the equivalent pure-Python implementation.
941
Michael W. Hudson774479c2005-04-18 08:46:17 +0000942- It is now safe to call PyGILState_Release() before
943 PyEval_InitThreads() (note that if there is reason to believe there
944 are multiple threads around you still must call PyEval_InitThreads()
945 before using the Python API; this fix is for extension modules that
946 have no way of knowing if Python is multi-threaded yet).
947
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000948- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
949 disabled caused a crash.
950
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000951- Bug #1165306: instancemethod_new allowed the creation of a method
952 with im_class == im_self == NULL, which caused a crash when called.
953
Tim Petersecc6e6a2005-07-10 22:30:55 +0000954- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000955 fixes the crash seen in bug #1165761
956
Raymond Hettinger96229b12005-03-11 06:49:40 +0000957- Added two new builtins, any() and all().
958
Brett Cannon409d8f22005-03-05 06:47:57 +0000959- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000960 (e.g., ``class C(): pass`` is no longer a syntax error).
961 Patch #1176012 added support to the 'parser' module and 'compiler' package
962 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000963
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000964- Patch #1115086: Support PY_LONGLONG in structmember.
965
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000966- Bug #1155938: new style classes did not check that __init__() was
967 returning None.
968
Tim Petersecc6e6a2005-07-10 22:30:55 +0000969- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000970 ('\') with a specific error message.
971
Martin v. Löwisff232d72005-03-03 09:24:38 +0000972- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
973
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000974- Bug #1124295: the __name__ attribute of file objects was
975 inadvertently made inaccessible in restricted mode.
976
Tim Petersecc6e6a2005-07-10 22:30:55 +0000977- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000978 an ferror() call.
979
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000980- min() and max() now support key= arguments with the same meaning as in
981 list.sort().
982
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000983- The peephole optimizer now performs simple constant folding in expressions:
984 (2+3) --> (5).
985
Raymond Hettingera422c342005-01-11 03:03:27 +0000986- set and frozenset objects can now be marshalled. SF #1098985.
987
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000988- Bug #1077106: Poor argument checking could cause memory corruption
989 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000990
Jeremy Hyltonab630502005-02-04 18:44:06 +0000991- The parser did not complain about future statements in illegal
992 positions. It once again reports a syntax error if a future
993 statement occurs after anything other than a doc string.
994
Neil Schemenauercf52c072005-08-12 17:34:58 +0000995- Change the %s format specifier for str objects so that it returns a
996 unicode instance if the argument is not an instance of basestring and
997 calling __str__ on the argument returns a unicode instance.
998
Tim Petersf4e69282006-02-27 17:15:31 +0000999- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1000 current thread state when the auto-GIL-state machinery knows about
1001 it (since the thread state is being deleted, continuing to remember it
1002 can't help, but can hurt if another thread happens to get created with
1003 the same thread id).
1004
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001005Extension Modules

1030
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001031- The unicodedata module was updated to the 4.1 version of the Unicode

1033 for applications that require this specific version (such as IDNA).
1034
Neal Norwitzb62c4332006-03-04 18:35:47 +00001035- The timing module is no longer built by default. It was deprecated

1040
Georg Brandldbd83392006-02-20 09:42:33 +00001041- Bug #854823: socketmodule now builds on Sun platforms even when

1058 are reported, the limit on path name lengths is removed, and stat reports
1059 WindowsError now (instead of OSError).
1060

1184 islice(s.start, s.stop, s.step)
1185

1193-------
1194
Nick Coghlan43832302006-04-23 17:04:07 +00001195- PEP 338: new module runpy defines a run_module function to support
1196 executing modules which provide access to source code or a code object
1197 via the PEP 302 import mechanisms.
1198
Anthony Baxter93f5b932006-04-03 08:05:07 +00001199- The email module's parsedate_tz function now sets the daylight savings

1207 in attribute values.
1208
Anthony Baxterc51ee692006-04-01 00:57:31 +00001209- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001210 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001211 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001212 module will not be built.
1213
Tim Petersc17976e2006-04-01 00:26:53 +00001214- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1215 aren't officially supported here, and trying to use them will probably
1216 raise an exception some day. But dicts have been allowed, and "mostly
1217 worked", so support for them won't go away without warning.
1218
Georg Brandl338ef7d2006-03-31 18:42:16 +00001219- Bug #1445068: getpass.getpass() can now be given an explicit stream

1229
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001230- Queue.Queue objects now support .task_done() and .join() methods
1231 to make it easier to monitor when daemon threads have completed
1232 processing all enqueued tasks. Patch #1455676.
1233
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001234- popen2.Popen objects now preserve the command in a .cmd attribute.
1235
Thomas Hellerc61c0492006-03-22 10:09:27 +00001236- Added the ctypes ffi package.
1237
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001238- email 4.0 package now integrated. This is largely the same as the email 3.0
1239 package that was included in Python 2.3, except that PEP 8 module names are
1240 now used (e.g. mail.message instead of email.Message). The MIME classes
1241 have been moved to a subpackage (e.g. email.mime.text instead of
1242 email.MIMEText). The old names are still supported for now. Several
1243 deprecated Message methods have been removed and lots of bugs have been
1244 fixed. More details can be found in the email package documentation.
1245
Walter Dörwald40108c92006-03-27 08:15:44 +00001246- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1247 (a subclass of tuple) that provides incremental decoders and encoders
1248 (a way to use stateful codecs without the stream API). Python functions
1249 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1250 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1251 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001252
Walter Dörwald067db482006-03-15 22:17:27 +00001253- Patch #1359365: Calling next() on a closed StringIO.String object raises
1254 a ValueError instead of a StopIteration now (like file and cString.String do).
1255 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1256 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001257
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001258- A regrtest option -w was added to re-run failed tests in verbose mode.

1270 and helpful context managers nested() and closing().
1271
Martin v. Löwis415ed932006-02-27 19:56:30 +00001272- The compiler package now supports future imports after the module docstring.

1331 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1332 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1333 Ronald L. Rivest offered this advice for Python:
1334
1335 "The consensus of researchers in this area (at least as
1336 expressed at the NIST Hash Function Workshop 10/31/05),
1337 is that SHA-256 is a good choice for the time being, but
1338 that research should continue, and other alternatives may
1339 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001340
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001341- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl268e61c2005-06-03 14:28:50 +00001443- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1444 component of the path.
1445
Skip Montanaro174dd222005-05-14 20:54:16 +00001446- Patch #1120353: The xmlrpclib module provides better, more transparent,
1447 support for datetime.{datetime,date,time} objects. With use_datetime set
1448 to True, applications shouldn't have to fiddle with the DateTime wrapper
1449 class at all.
1450
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001451- distutils.commands.upload was added to support uploading distribution
1452 files to PyPI.
1453
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001454- distutils.commands.register now encodes the data as UTF-8 before posting
1455 them to PyPI.
1456
Raymond Hettinger267b8682005-03-27 10:47:39 +00001457- decimal operator and comparison methods now return NotImplemented
1458 instead of raising a TypeError when interacting with other types. This
1459 allows other classes to implement __radd__ style methods and have them
1460 work as expected.
1461
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001462- Bug #1163325: Decimal infinities failed to hash. Attempting to
1463 hash a NaN raised an InvalidOperation instead of a TypeError.
1464
Tim Petersecc6e6a2005-07-10 22:30:55 +00001465- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001466 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1467
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001468- Patch #1043890: Add extractall method to tarfile.
1469
Martin v. Löwisc72dd382005-03-04 13:50:17 +00001470- Patch #1075887: Don't require MSVC in distutils if there is nothing
1471 to build.
1472
Martin v. Löwis637431b2005-03-03 23:12:42 +00001473- Patch #1103407: Properly deal with tarfile iterators when untarring
1474 symbolic links on Windows.
1475
Tim Petersecc6e6a2005-07-10 22:30:55 +00001476- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001477 profile.py if available.
1478
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001479- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1480
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001481- Patch #1117454: Remove code to special-case cookies without values
1482 in LWPCookieJar.
1483
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001484- Patch #1117339: Add cookielib special name tests.
1485
Martin v. Löwise869eb12005-03-03 09:46:07 +00001486- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1487
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001488- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1489
Martin v. Löwisdf241532005-03-03 08:17:42 +00001490- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1491
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001492- Patch #1104111: Alter setup.py --help and --help-commands.
1493
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001494- Patch #1121234: Properly cleanup _exit and tkerror commands.
1495
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001496- Patch #1049151: xdrlib now unpacks booleans as True or False.
1497
Raymond Hettingerbab41432005-02-05 01:31:19 +00001498- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1499
Guido van Rossumd0641422005-02-03 15:01:24 +00001500- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1501 disables recursive traversal through instance attributes, which can
1502 be exploited in various ways.
1503
Tim Peterse3547fd2005-12-16 23:13:57 +00001504- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001505 flags on the HTTP listening socket.
1506
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001507- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1508 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1509
Tim Peterse3547fd2005-12-16 23:13:57 +00001510- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001511 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1512
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001513- Bug #1110478: Revert os.environ.update to do putenv again.
1514
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001515- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1516
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001517- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1518
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001519- Enhancements to the csv module:
1520
1521 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001522 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001523 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001524 + Dialect parameter parsing has been re-implemented to improve error
1525 reporting.
1526 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1527 dictates.
1528 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001529 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001530 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001531 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1532 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001533 + reader now allows \r characters to be quoted (previously it only allowed
1534 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001535 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001536 + Dialect classes passed to the module are no longer instantiated by
1537 the module before being parsed (the former validation scheme required
1538 this, but the mechanism was unreliable).
1539 + The dialect registry now contains instances of the internal
1540 C-coded dialect type, rather than references to python objects.
1541 + the internal c-coded dialect type is now immutable.
1542 + register_dialect now accepts the same keyword dialect specifications
1543 as the reader and writer, allowing the user to register dialects
1544 without first creating a dialect class.
1545 + a configurable limit to the size of parsed fields has been added -
1546 previously, an unmatched quote character could result in the entire
1547 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001548 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001549 the parser field size limit (returning the former limit). The initial
1550 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001551 + A line_num attribute has been added to the reader object, which tracks
1552 the number of lines read from the source iterator. This is not
1553 the same as the number of records returned, as records can span
1554 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001555 + reader and writer objects were not being registered with the cyclic-GC.
1556 This has been fixed.
1557
Brett Cannone6539c42005-01-08 02:43:53 +00001558- _DummyThread objects in the threading module now delete self.__block that is
1559 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1560 lock primitives tend to be limited in number and thus should not be wasted on
1561 a _DummyThread object. Fixes bug #1089632.
1562
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001563- The imghdr module now detects Exif files.
1564
Raymond Hettinger6065d322004-12-20 23:51:53 +00001565- StringIO.truncate() now correctly adjusts the size attribute.
1566 (Bug #951915).
1567
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001568- locale.py now uses an updated locale alias table (built using
1569 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1570 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001571 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001572
Raymond Hettinger3557f422004-12-07 12:02:02 +00001573- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1574
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001575- the pickle module no longer accepts the deprecated None option in the
1576 args tuple returned by __reduce__().
1577
Brett Cannon84667c02004-12-07 03:25:18 +00001578- optparse now optionally imports gettext. This allows its use in setup.py.
1579
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001580- the pickle module no longer uses the deprecated bin parameter.
1581
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001582- the shelve module no longer uses the deprecated binary parameter.
1583
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001584- the pstats module no longer uses the deprecated ignore() method.
1585
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001586- the filecmp module no longer uses the deprecated use_statcache argument.
1587
Raymond Hettinger664347b2004-12-04 21:21:53 +00001588- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1589 extended or overridden by subclasses. Formerly, the subclassed method would
1590 be ignored by the rest of the module. (Bug #1078905).
1591
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001592- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001593 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001594
Walter Dörwald36733692004-12-22 12:50:50 +00001595- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1596 once when a size argument is given. This prevents a buffer overflow in the
1597 tokenizer with very long source lines.
1598
Barry Warsaw538561e2006-01-01 21:48:54 +00001599- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1600 immediately after creating the object, without any intervening
1601 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001602
Skip Montanaro05885812005-01-16 20:48:27 +00001603- The reconvert.quote function can now emit triple-quoted strings. The
1604 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001605
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001606- ``UserString.MutableString`` now supports negative indices in
1607 ``__setitem__`` and ``__delitem__``
1608
Greg Ward40407942005-03-05 02:53:17 +00001609- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1610 correctly.
1611
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001612- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1613 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1614 character even if the user has passed a size parameter to get a proper
1615 line ending. Remove the special handling of a "\r\n" that has been split
1616 between two lines.
1617
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001618- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1619 about illegal code points. The codec now supports PEP 293 style error
1620 handlers.
1621
Walter Dörwald78a78b02005-09-01 12:04:29 +00001622- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001623 from the input stream, so that the output is a byte string in the correct
1624 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001625
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001626- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1627 considering it exactly like a '*'.
1628
Walter Dörwald007f8df2005-10-09 19:42:27 +00001629- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1630 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001631
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001632- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1633
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001634- Patch #1413711: Certain patterns of differences were making difflib
1635 touch the recursion limit.
1636
Walter Dörwald58917a62006-03-31 15:26:22 +00001637- Bug #947906: An object oriented interface has been added to the calendar
1638 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001639 called as a script (e.g. via ``python -mcalendar``). Localized month and
1640 weekday names can be ouput (even if an exotic encoding is used) using
1641 special classes that use unicode.

1644-----
1645
Neal Norwitz602d3392006-03-31 08:21:40 +00001646- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1647 by using -mieee gcc option.
1648
Martin v. Löwis86d66262006-02-17 08:40:11 +00001649- Patch #1432345: Make python compile on DragonFly.
1650
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001651- Build support for Win64-AMD64 was added.
1652
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001653- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1654
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001655- Patch #881820: look for openpty and forkpty also in libbsd.
1656
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001657- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1658 The zlib module is now builtin on Windows.
1659
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001660- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1661
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001662- Bug #1189330: configure did not correctly determine the necessary
1663 value of LINKCC if python was built with GCC 4.0.
1664
Trent Mick8321b422005-07-26 02:29:21 +00001665- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1666 vulnerability in zlib 1.2.1 and 1.2.2.
1667
Brett Cannon08cd5982005-04-24 22:26:38 +00001668- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1669 flags that change binary compatibility. Changes were also made to
1670 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001671 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001672
Bob Ippolitoed233462005-03-29 13:47:59 +00001673- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1674 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1675 no longer exists). This configure patch makes things right.
1676
Martin v. Löwise2713be2005-03-08 15:03:08 +00001677- Bug #1158607: Build with --disable-unicode again.
1678
Brett Cannon46d96232005-02-16 00:07:19 +00001679- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1680 defined. Discovered as a result of not being able to build on OS X.
1681
Brett Cannon516592f2004-12-07 00:42:59 +00001682- setup.py now uses the directories specified in LDFLAGS using the -L option
1683 and in CPPFLAGS using the -I option for adding library and include
1684 directories, respectively, for compiling extension modules against. This has
1685 led to the core being compiled using the values in CPPFLAGS. It also removes
1686 the need for the special-casing of both DarwinPorts and Fink for darwin since
1687 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1688 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1689 Fink, ``-I/opt/local/include`` for DarwinPorts).
1690
Brett Cannon43802422005-02-10 20:48:03 +00001691- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1692 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1693 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1694 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001696C API
1697-----
1698
Tim Petersc9d78aa2006-03-26 23:27:58 +00001699- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1700 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1701 is obtained via the ``PyObject_`` family, it must be released via the
1702 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1703 always been officially true, but when Python's small-object allocator was
1704 introduced, an attempt was made to cater to a few extension modules
1705 discovered at the time that obtained memory via ``PyObject_New`` but
1706 released it via ``PyMem_DEL``. It's years later, and if such code still
1707 exists it will fail now (probably with segfaults, but calling wrong
