Hye-Shik Change6a1cb92006-06-23 21:16:18 +000015- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
16 omit a default "error" argument for NULL pointer. This allows
17 the parser to take a codec from cjkcodecs again.

Brett Cannon53ab5b72006-06-22 16:49:14 +000022- Bug #1510580: The 'warnings' module improperly required that a Warning
23 category be either a types.ClassType and a subclass of Warning. The proper
24 check is just that it is a subclass with Warning as the documentation states.
25
Georg Brandlad29e632006-06-21 17:45:17 +000026- The compiler module now correctly compiles the new try-except-finally
27 statement (bug #1509132).
28
Neal Norwitz60373cd2006-06-22 06:30:50 +000029- The wsgiref package is now installed properly on Unix.

43Core and builtins
44-----------------
45
Georg Brandla56b9152006-06-19 06:35:54 +000046- Patch #1507676: Error messages returned by invalid abstract object operations
47 (such as iterating over an integer) have been improved and now include the
48 type of the offending object to help with debugging.
49
Brett Cannonea3912b2006-06-13 21:46:41 +000050- Bug #992017: A classic class that defined a __coerce__() method that returned
51 its arguments swapped would infinitely recurse and segfault the interpreter.
52
Neal Norwitz909eb122006-06-12 02:13:21 +000053- Fix the socket tests so they can be run concurrently.
54
Neal Norwitzb9845e72006-06-12 02:11:18 +000055- Removed 5 integers from C frame objects (PyFrameObject).
56 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
57
Brett Cannon22565aa2006-06-09 22:31:23 +000058- Bug #532646: object.__call__() will continue looking for the __call__
59 attribute on objects until one without one is found. This leads to recursion
60 when you take a class and set its __call__ attribute to an instance of the
61 class. Originally fixed for classic classes, but this fix is for new-style.
62 Removes the infinite_rec_3 crasher.
63
Georg Brandl24250812006-06-09 18:45:48 +000064- The string and unicode methods startswith() and endswith() now accept
65 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
66
Brett Cannonde3b0522006-06-08 17:00:45 +000067- Buffer objects, at the C level, never used the char buffer
68 implementation even when the char buffer for the wrapped object was
69 explicitly requested (originally returned the read or write buffer).
70 Now a TypeError is raised if the char buffer is not present but is
71 requested.
72
Georg Brandlddbaa662006-06-04 21:56:52 +000073- Patch #1346214: Statements like "if 0: suite" are now again optimized
74 away like they were in Python 2.4.
75
Georg Brandlb7c8f542006-05-27 12:30:25 +000076- Builtin exceptions are now full-blown new-style classes instead of
77 instances pretending to be classes, which speeds up exception handling
78 by about 80% in comparison to 2.5a2.
79
Martin v. Löwisd004fc82006-05-27 08:36:52 +000080- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
81 Unicode 4.1.
82
Georg Brandlf4ef1162006-05-26 18:03:31 +000083- Patch #921466: sys.path_importer_cache is now used to cache valid and
84 invalid file paths for the built-in import machinery which leads to
85 fewer open calls on startup.
86
Tim Peters696cf432006-05-24 21:10:40 +000087- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
88 of-2 bases. The largest speedup is for inputs with about 1000 decimal
89 digits. Conversion from non-power-of-2 bases remains quadratic-time in
90 the number of input digits (it was and remains linear-time for bases
91 2, 4, 8, 16 and 32).
92
Tim Petersb713ec22006-05-23 18:45:30 +000093- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
94 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
95 an integer close to ``sys.maxint``. This was repaired by patch
96 #1335972, which also gives a nice speedup.
97
Richard Jonescebbefc2006-05-23 18:28:17 +000098- Patch #1337051: reduced size of frame objects.
99
100- PyErr_NewException now accepts a tuple of base classes as its
101 "base" parameter.
102
Richard Jones7c88dcc2006-05-23 10:37:38 +0000103- Patch #876206: function call speedup by retaining allocated frame
104 objects.
105
Georg Brandl7b90e162006-05-18 07:01:27 +0000106- Bug #1462152: file() now checks more thoroughly for invalid mode
107 strings and removes a possible "U" before passing the mode to the
108 C library function.
109
Neal Norwitz1004a532006-05-15 07:17:23 +0000110- Patch #1488312, Fix memory alignment problem on SPARC in unicode
111
Neal Norwitz373f0a72006-05-15 07:04:36 +0000112- Bug #1487966: Fix SystemError with conditional expression in assignment
113
Martin v. Löwis879768d2006-05-11 13:28:43 +0000114- WindowsError now has two error code attributes: errno, which carries
115 the error values from errno.h, and winerror, which carries the error
116 values from winerror.h. Previous versions put the winerror.h values
117 (from GetLastError()) into the errno attribute.
118
Martin v. Löwis77736712006-05-04 05:51:03 +0000119- Patch #1475845: Raise IndentationError for unexpected indent.
120
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000121- Patch #1479181: split open() and file() from being aliases for each other.
122
Tim Peters44bd9862006-06-01 13:49:23 +0000123- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
124 methods were always silently ignored by dictionaries when comparing keys.
125 They are now passed through (except when using the C API function
126 ``PyDict_GetItem()``, whose semantics did not change).
127
128- Bug #1456209: In some obscure cases it was possible for a class with a
129 custom ``__eq__()`` method to confuse dict internals when class instances
130 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
131 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000133Extension Modules
134-----------------
135
Brett Cannon6ee7d012006-06-08 16:23:04 +0000136- Change binascii.hexlify to accept a read-only buffer instead of only a char
137 buffer and actually follow its documentation.
138
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000139- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
140
Nick Coghlanc649ec52006-05-29 12:43:05 +0000141- Patch #1478788 (modified version): The functional extension module has
142 been renamed to _functools and a functools Python wrapper module added.
143 This provides a home for additional function related utilities that are
144 not specifically about functional programming. See PEP 309.
145
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000146- Patch #1493701: performance enhancements for struct module.
147
Georg Brandl378d5922006-05-17 14:26:50 +0000148- Patch #1490224: time.altzone is now set correctly on Cygwin.
149
Georg Brandl8d3342b2006-05-16 07:38:27 +0000150- Patch #1435422: zlib's compress and decompress objects now have a
151 copy() method.
152
Andrew MacIntyre92913322006-06-13 15:04:24 +0000153- Patch #1454481: thread stack size is now tunable at runtime for thread
154 enabled builds on Windows and systems with Posix threads support.
155
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000156- On Win32, os.listdir now supports arbitrarily-long Unicode path names
157 (up to the system limit of 32K characters).
158
159- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
160 As a result, these functions now raise WindowsError instead of OSError.
161
Tim Peters7a822da2006-05-25 21:50:17 +0000162- ``time.clock()`` on Win64 should use the high-performance Windows
163 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
164 Windows platforms).
165
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000166- Calling Tk_Init twice is refused if the first call failed as that
167 may deadlock.
168
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000169- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
170 accept it without potentially using an uninitialized pointer.
171
172- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
173 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
174 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000175
Gregory P. Smith372b5832006-06-05 18:48:21 +0000176- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000177 [pybsddb project SF patch number 1466734]
178
Gregory P. Smith372b5832006-06-05 18:48:21 +0000179- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
180 parameter is supplied. [SF pybsddb bug #1477863]
181
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000182- bsddb: the __len__ method of a DB object has been fixed to return correct
183 results. It could previously incorrectly return 0 in some cases.
184 Fixes SF bug 1493322 (pybsddb bug 1184012).
185
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000186- bsddb: the bsddb.dbtables Modify method now raises the proper error and
187 aborts the db transaction safely when a modifier callback fails.
188 Fixes SF python patch/bug #1408584.
189
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000190- bsddb: multithreaded DB access using the simple bsddb module interface
191 now works reliably. It has been updated to use automatic BerkeleyDB
192 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
193 database calls that would previously deadlock. [SF python bug #775414]
194
Ronald Oussoren143cefb2006-06-15 08:14:18 +0000195- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000196
Walter Dörwald4994d952006-06-19 08:07:50 +0000197- Patch #1506645: add Python wrappers for the curses functions
198 is_term_resized, resize_term and resizeterm.

201-------
202
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000203- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
204 functions.
205
Martin v. Löwis3798da02006-06-17 18:44:27 +0000206- Patch #812986: Update turtle output even if not tracing.
207
Martin v. Löwis92733be2006-06-17 09:25:15 +0000208- Patch #1494750: Destroy master after deleting children in
209 Tkinter.BaseWidget.
210
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000211- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
212
Martin v. Löwis337487e2006-06-17 09:15:14 +0000213- Patch #763580: Add name and value arguments to Tkinter variable
214 classes.
215
Georg Brandl83cc0d02006-06-14 08:50:03 +0000216- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
217 mime.types file for determining MIME types.
218
Georg Brandl2605ca82006-06-14 06:08:31 +0000219- Bug #1339007: Shelf objects now don't raise an exception in their
220 __del__ method when initialization failed.
221
Martin v. Löwisd8251432006-06-14 05:21:04 +0000222- Patch #1455898: The MBCS codec now supports the incremental mode for
223 double-byte encodings.
224
Tim Peters43898b42006-06-14 04:09:25 +0000225- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
226 guarantee that adjacent triples in the return list always describe
227 non-adjacent blocks. Previously, a pair of matching blocks could end
228 up being described by multiple adjacent triples that formed a partition
229 of the matching pair.
230
Greg Ward0e0c9f42006-06-11 16:24:11 +0000231- Bug #1498146: fix optparse to handle Unicode strings in option help,
232 description, and epilog.
233
Greg Wardd1c797e2006-06-11 14:42:41 +0000234- Bug #1366250: minor optparse documentation error.
235
Greg Ward7f547402006-06-11 00:40:49 +0000236- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
237 clarify docs.
238
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000239- The wsgiref package has been added to the standard library.
240
Nick Coghlan676725d2006-06-08 13:54:49 +0000241- The functions update_wrapper() and wraps() have been added to the functools
242 module. These make it easier to copy relevant metadata from the original
243 function when writing wrapper functions.
244
Tim Petersd6a9eef2006-06-05 01:48:21 +0000245- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
246 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000247
Martin v. Löwis3f767792006-06-04 19:36:28 +0000248- Patch #1359618: Speed up charmap encoder by using a trie structure
249 for lookup.
250
Tim Petersd609b1a2006-06-02 23:22:51 +0000251- The functions in the ``pprint`` module now sort dictionaries by key
252 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
253 if and only if its display required more than one line, although that
254 wasn't documented. The new behavior increases predictability; e.g.,
255 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
256
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000257- Patch #1497027: try HTTP digest auth before basic auth in urllib2
258 (thanks for J. J. Lee).
259
Georg Brandl2b330372006-05-28 20:23:12 +0000260- Patch #1496206: improve urllib2 handling of passwords with respect to
261 default HTTP and HTTPS ports.
262
George Yoshidaf3c65de2006-05-28 16:39:09 +0000263- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
264
Bob Ippolito7298f272006-05-23 18:43:47 +0000265- Patch #1281707: speed up gzip.readline.
266
Georg Brandlb89316f2006-05-17 15:51:16 +0000267- Patch #1180296: Two new functions were added to the locale module:
268 format_string() to get the effect of "format % items" but locale-aware,
269 and currency() to format a monetary number with currency sign.
270
Georg Brandle3a25832006-05-17 14:56:04 +0000271- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
272 and several features added, such as speed and geometry control.
273
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000274- Patch #1488881: add support for external file objects in bz2 compressed
275 tarfiles.
276
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000277- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
278 stdout arguments, making it possible to redirect input and output
279 for remote debugging.
280
281- Patch #1484695: Update the tarfile module to version 0.8. This fixes
282 a couple of issues, notably handling of long file names using the
283 GNU LONGNAME extension.
284
285- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
286 new flag when ``name`` is already the name of an option flag.
287
288- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
289 package.
290
291- Patch #1472854: make the rlcompleter.Completer class usable on non-
292 UNIX platforms.
293
294- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
295
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000296- Bug #1472827: correctly escape newlines and tabs in attribute values in
297 the saxutils.XMLGenerator class.

332Core and builtins
333-----------------
334
Thomas Heller1b046642006-04-18 18:51:06 +0000335- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
336 by converting these apis from macros into exported functions again:
337
338 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
339 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
340 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
341 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
342 PyRun_String Py_CompileString
343
Martin v. Löwis45294a92006-04-18 06:24:08 +0000344- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
345
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000346- All uses of PyStructSequence_InitType have been changed to initialize
347 the type objects only once, even if the interpreter is initialized
348 multiple times.
349
Neal Norwitz61546162006-04-14 05:20:28 +0000350- Bug #1454485, array.array('u') could crash the interpreter. This was
351 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
352 to unicode when it didn't make sense. 'u#' now requires a unicode string.
353
354- Py_UNICODE is unsigned. It was always documented as unsigned, but
355 due to a bug had a signed value in previous versions.
356
Tim Peters3a5e8b12006-04-11 01:44:07 +0000357- Patch #837242: ``id()`` of any Python object always gives a positive
358 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
359 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000360 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000361 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000362
Tim Peters3a5e8b12006-04-11 01:44:07 +0000363 def __hash__(self):
364 return id(self) # WRONG
365
366 because a hash result must be a (short) Python int but it was always
367 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000368 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000369 was always usable as a hash value before this patch. That's no longer
370 necessarily so.
371
372- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000373 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000374 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000375 #1454844)
376
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000377- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
378 involving generators that have paused outside of any ``try`` or ``with``
379 blocks. (In 2.5a1, a paused generator that was part of a reference
380 cycle could not be garbage collected, regardless of whether it was
381 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000383Extension Modules
384-----------------
385
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000386- Patch #1191065: Fix preprocessor problems on systems where recvfrom
387 is a macro.
388
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000389- Bug #1467952: os.listdir() now correctly raises an error if readdir()
390 fails with an error condition.
391
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000392- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
393
394- Bug #1117761: bsddb.*open() no longer raises an exception when using
395 the cachesize parameter.
396
397- Bug #1149413: bsddb.*open() no longer raises an exception when using
398 a temporary db (file=None) with the 'n' flag to truncate on open.
399
400- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
401 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000402
Armin Rigoa9017c32006-04-19 11:50:27 +0000403- Patch #1062014: AF_UNIX sockets under Linux have a special
404 abstract namespace that is now fully supported.
405
Anthony Baxter51bcb682006-04-05 14:51:42 +0000406Library
407-------
408
Tim Peters711bf302006-04-25 03:31:36 +0000409- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
410 a doctest to be skipped (the code is not run, and the expected output
411 or exception is ignored).
412
Nick Coghlanda2268f2006-04-24 04:37:15 +0000413- Fixed contextlib.nested to cope with exceptions being raised and
414 caught inside exit handlers.
415
Greg Wardab05edc2006-04-23 03:47:58 +0000416- Updated optparse module to Optik 1.5.1 (allow numeric constants in
417 hex, octal, or binary; add ``append_const`` action; keep going if
418 gettext cannot be imported; added ``OptionParser.destroy()`` method;
419 added ``epilog`` for better help generation).
420
Tim Peters21fbd572006-04-21 21:18:10 +0000421- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
422 called from a thread spawned as a side effect of importing a module.
423
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000424- The pydoc module now supports documenting packages contained in
425 .zip or .egg files.
426
427- The pkgutil module now has several new utility functions, such
428 as ``walk_packages()`` to support working with packages that are either
429 in the filesystem or zip files.
430
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000431- The mailbox module can now modify and delete messages from
432 mailboxes, in addition to simply reading them. Thanks to Gregory
433 K. Johnson for writing the code, and to the 2005 Google Summer of
434 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000435
Tim Petersc7605f22006-04-17 21:12:33 +0000436- The ``__del__`` method of class ``local`` in module ``_threading_local``
437 returned before accomplishing any of its intended cleanup.
438
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000439- Patch #790710: Add breakpoint command lists in pdb.
440
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000441- Patch #1063914: Add Tkinter.Misc.clipboard_get().
442
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000443- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
444
Anthony Baxtere29002c2006-04-12 12:07:31 +0000445- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
446 Windows. Bug #1469163.
447
Phillip J. Eby47032112006-04-11 01:07:43 +0000448- The warnings, linecache, inspect, traceback, site, and doctest modules
449 were updated to work correctly with modules imported from zipfiles or
450 via other PEP 302 __loader__ objects.
451
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000452- Patch #1467770: Reduce usage of subprocess._active to processes which
453 the application hasn't waited on.
454
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000455- Patch #1462222: Fix Tix.Grid.
456
Neal Norwitza31bf182006-04-09 03:35:43 +0000457- Fix exception when doing glob.glob('anything*/')
458
Skip Montanaro262fb922006-04-21 02:31:07 +0000459- The pstats.Stats class accepts an optional stream keyword argument to
460 direct output to an alternate file-like object.
461
Anthony Baxter51bcb682006-04-05 14:51:42 +0000462Build
463-----
464
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000465- The Makefile now has a reindent target, which runs reindent.py on
466 the library.
467
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000468- Patch #1470875: Building Python with MS Free Compiler
469
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000470- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000471
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000472- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
473 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000474 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000475 CXX from --with-cxx-main, see description in README.
476
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000477- Patch #1429775: Link extension modules with the shared libpython.
478
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000479- Fixed a libffi build problem on MIPS systems.
480
Tim Peters8931ff12006-05-13 23:28:20 +0000481- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
482 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
483 and "%zu" for unsigned integers of type ``size_t``.
484
Anthony Baxter51bcb682006-04-05 14:51:42 +0000485Tests
486-----
487
Nick Coghlanda2268f2006-04-24 04:37:15 +0000488- test_contextlib now checks contextlib.nested can cope with exceptions
489 being raised and caught inside exit handlers.
490
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000491- test_cmd_line now checks operation of the -m and -c command switches
492
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000493- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
494 it separately and by hand. It also wasn't cleaning up its changes to
495 the current Decimal context.
496
Thomas Woutersabd08882006-04-26 15:53:30 +0000497- regrtest.py now has a -M option to run tests that test the new limits of
498 containers, on 64-bit architectures. Running these tests is only sensible
499 on 64-bit machines with more than two gigabytes of memory. The argument
500 passed is the maximum amount of memory for the tests to use.
501
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +0000502Tools
503-----
504
505- Added the Python benchmark suite pybench to the Tools/ directory;
506 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000508Documentation
509-------------
510
Tim Petersb06d28c2006-05-12 01:57:59 +0000511- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
512
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000513- PEP 343: Added Context Types section to the library reference
514 and attempted to bring other PEP 343 related documentation into
515 line with the implementation and/or python-dev discussions.
516
Tim Peters8dc73d22006-04-24 02:03:16 +0000517- Bug #1337990: clarified that ``doctest`` does not support examples
518 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000521What's New in Python 2.5 alpha 1?
522=================================
523
Anthony Baxterebed3f62006-04-03 15:03:44 +0000524*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000525
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000526Core and builtins
527-----------------
528
Nick Coghlan43832302006-04-23 17:04:07 +0000529- PEP 338: -m command line switch now delegates to runpy.run_module
530 allowing it to support modules in packages and zipfiles
531
Martin v. Löwisc661b882006-04-20 04:54:23 +0000532- On Windows, .DLL is not an accepted file name extension for
533 extension modules anymore; extensions are only found if they
534 end in .PYD.
535
Martin v. Löwisea62d252006-04-03 10:56:49 +0000536- Bug #1421664: sys.stderr.encoding is now set to the same value as
537 sys.stdout.encoding.
538
Neal Norwitz92e212f2006-04-03 04:48:37 +0000539- __import__ accepts keyword arguments.
540
Georg Brandlccadf842006-03-31 18:54:53 +0000541- Patch #1460496: round() now accepts keyword arguments.
542
Anthony Baxter262c00a2006-03-30 10:53:17 +0000543- Fixed bug #1459029 - unicode reprs were double-escaped.
544
Hye-Shik Changd478f342006-03-23 12:32:36 +0000545- Patch #1396919: The system scope threads are reenabled on FreeBSD
546 5.4 and later versions.
547
Neal Norwitze98ccf62006-03-23 05:39:47 +0000548- Bug #1115379: Compiling a Unicode string with an encoding declaration
549 now gives a SyntaxError.
550
Georg Brandlabd1ff82006-03-18 07:59:59 +0000551- Previously, Python code had no easy way to access the contents of a
552 cell object. Now, a ``cell_contents`` attribute has been added
553 (closes patch #1170323).
554
Tim Peterscf79aac2006-03-16 01:14:46 +0000555- Patch #1123430: Python's small-object allocator now returns an arena to
556 the system ``free()`` when all memory within an arena becomes unused
557 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
558 freed. Some applications will see a drop in virtual memory size now,
559 especially long-running applications that, from time to time, temporarily
560 use a large number of small objects. Note that when Python returns an
561 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000562 platform C library will in turn return that memory to the operating system.
563 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000564 appears to be effective at least on Microsoft C and gcc-based systems.
565 Thanks to Evan Jones for hard work and patience.
566
Georg Brandl533ff6f2006-03-08 18:09:27 +0000567- Patch #1434038: property() now uses the getter's docstring if there is
568 no "doc" argument given. This makes it possible to legitimately use
569 property() as a decorator to produce a read-only property.
570
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000571- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
572 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
573 of requiring an int or long in slicing and a few other contexts, enabling
574 other objects (e.g. Numeric Python's integers) to be used as slice indices.
575
Neal Norwitz995acdf2006-03-07 05:01:00 +0000576- Fixed various bugs reported by Coverity's Prevent tool.
577
Brett Cannonbf364092006-03-01 04:25:17 +0000578- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
579 new exception base class, BaseException, which has a new message attribute.
580 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
581 Raising a string exception now raises a DeprecationWarning.
582
Thomas Woutersfb609f42006-02-28 16:37:25 +0000583- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
584 explicitly relative, using 'from .module import name' to mean 'from the same
585 package as this module is in. Imports without dots still default to the
586 old relative-then-absolute, unless 'from __future__ import
587 absolute_import' is used.
588
Brett Cannona7446e32006-02-27 23:39:10 +0000589- Properly check if 'warnings' raises an exception (usually when a filter set
590 to "error" is triggered) when raising a warning for raising string
591 exceptions.
592
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000593- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000594 The name was removed from Include/code.h.
595
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000596- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000597
Guido van Rossum1968ad32006-02-25 22:38:04 +0000598- Patch 1433928:
599 - The copy module now "copies" function objects (as atomic objects).
600 - dict.__getitem__ now looks for a __missing__ hook before raising
601 KeyError.
602
Tim Peters84ef21c2006-02-28 20:39:06 +0000603- PEP 343: with statement implemented. Needs ``from __future__ import
604 with_statement``. Use of 'with' as a variable will generate a warning.
605 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000606 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000607 The following objects have __context__ methods:
608 - The built-in file type.
609 - The thread.LockType type.
610 - The following types defined by the threading module:
611 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
612 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000613
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000614- Fix the encodings package codec search function to only search
615 inside its own package. Fixes problem reported in patch #1433198.
616
617 Note: Codec packages should implement and register their own
618 codec search function. PEP 100 has the details.
619
Tim Peters9ea89d22006-06-04 03:26:02 +0000620- PEP 353: Using ``Py_ssize_t`` as the index type.
621
622- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
623 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
624 now allow Python to make use of memory blocks exceeding 2**32 bytes for
625 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
626 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000627
Neal Norwitzfc76d632006-01-10 06:03:13 +0000628- Patch #1400181, fix unicode string formatting to not use the locale.
629 This is how string objects work. u'%f' could use , instead of .
630 for the decimal point. Now both strings and unicode always use periods.
631
Neal Norwitz671b9e32006-01-09 07:07:12 +0000632- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
633 configure would break checking curses.h.
634
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000635- Bug #959576: The pwd module is now builtin. This allows Python to be
636 built on UNIX platforms without $HOME set.
637

639
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000640- Bug #889500, fix line number on SyntaxWarning for global declarations.
641
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000642- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
643
Neal Norwitze7214a12005-12-18 05:03:17 +0000644- Support for converting hex strings to floats no longer works.
645 This was not portable. float('0x3') now raises a ValueError.
646
Barry Warsaw2a38a862005-12-18 01:27:35 +0000647- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000648 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000649 is now displayed in interactive prompt banner.
650
Georg Brandlfa166682005-12-17 21:45:17 +0000651- Implementation of PEP 341 - Unification of try/except and try/finally.
652 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000653 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000654
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000655- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
656 now encodes backslash correctly.
657
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000658- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
659
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000660- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000661 and long longs.
662
Neal Norwitz67715f02005-11-09 06:59:35 +0000663- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000664 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000665 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000666
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000667- Replaced most Unicode charmap codecs with new ones using the
668 new Unicode translate string feature in the builtin charmap
669 codec; the codecs were created from the mapping tables available
670 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
671 encodings now include a mapping for the Apple logo)
672
Tim Peterse3547fd2005-12-16 23:13:57 +0000673- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000674
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000675- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000676
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000677- A new AST parser implementation was completed. The abstract
678 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000679 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000680
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000681- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000682 The following code now raises a SyntaxError: foo(a = i for i in range(10))
683
Neal Norwitz708e51a2005-10-03 04:48:15 +0000684- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
685
Neal Norwitz11bd1192005-10-03 00:54:56 +0000686- SF Bug #887946: fix segfault when redirecting stdin from a directory.
687 Provide a warning when a directory is passed on the command line.
688
Neal Norwitz40d37812005-10-02 01:48:49 +0000689- Fix segfault with invalid coding.
690
691- SF bug #772896: unknown encoding results in MemoryError.
692
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000693- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000694 supported a __len__() method which evaluated to False when the iterator
695 was empty.
696
Guido van Rossum630db602005-09-20 18:49:54 +0000697- On 64-bit platforms, when __len__() returns a value that cannot be
698 represented as a C int, raise OverflowError.
699
Skip Montanarof8948ca2005-09-19 03:54:46 +0000700- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000701 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000702
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000703- SF bug #893549: parsing keyword arguments was broken with a few format
704 codes.
705
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000706- Changes donated by Elemental Security to make it work on AIX 5.3
707 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
708 bug #105470: test_pwd fails on 64bit system (Opteron).
709
Guido van Rossum539c6622005-09-14 17:49:54 +0000710- Changes donated by Elemental Security to make it work on HP-UX 11 on
711 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
712
Georg Brandl4550b8d2005-08-26 06:43:52 +0000713- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000714 (fixes bug #1119418).
715
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000716- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
717
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000718- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
719 exceptions that cause a function to exit.
720
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000721- The implementation of set() and frozenset() was revised to use its
722 own internal data structure. Memory consumption is reduced by 1/3
723 and there are modest speed-ups as well. The API is unchanged.
724
Tim Petersde7990b2005-07-17 23:45:23 +0000725- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
726
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000727- SF bug #1229429: PyObject_CallMethod failed to decrement some
728 reference counts in some error exit cases.
729
Tim Petersecc6e6a2005-07-10 22:30:55 +0000730- SF bug #1185883: Python's small-object memory allocator took over
731 a block managed by the platform C library whenever a realloc specified
732 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000733 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000734 portable way to copy data from the C-managed block into Python's
735 small-object space without risking a memory fault. Python's small-object
736 realloc now leaves such blocks under the control of the platform C
737 realloc.
738
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000739- SF bug #1232517: An overflow error was not detected properly when
740 attempting to convert a large float to an int in os.utime().
741
Raymond Hettinger3296e692005-06-29 23:29:56 +0000742- SF bug #1224347: hex longs now print with lowercase letters just
743 like their int counterparts.
744
Michael W. Hudson188d4362005-06-20 16:52:57 +0000745- SF bug #1163563: the original fix for bug #1010677 ("thread Module
746 Breaks PyGILState_Ensure()") broke badly in the case of multiple
747 interpreter states; back out that fix and do a better job (see
748 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
749 for a longer write-up of the problem).
750
Michael W. Hudsondf888462005-06-03 14:41:55 +0000751- SF patch #1180995: marshal now uses a binary format by default when
752 serializing floats.
753
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000754- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
755 the routines that promise to produce IEEE 754 binary representations
756 of floats now simply copy bytes around.
757
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000758- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
759 278.
760
Brett Cannonc3647ac2005-04-26 03:45:26 +0000761- patch #1109424: int, long, float, complex, and unicode now check for the
762 proper magic slot for type conversions when subclassed. Previously the
763 magic slot was ignored during conversion. Semantics now match the way
764 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000765 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000766 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000767 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000768
Barry Warsawc8d907c2005-04-19 23:43:40 +0000769- Descriptors defined in C with a PyGetSetDef structure, where the setter is
770 NULL, now raise an AttributeError when attempting to set or delete the
771 attribute. Previously a TypeError was raised, but this was inconsistent
772 with the equivalent pure-Python implementation.
773
Michael W. Hudson774479c2005-04-18 08:46:17 +0000774- It is now safe to call PyGILState_Release() before
775 PyEval_InitThreads() (note that if there is reason to believe there
776 are multiple threads around you still must call PyEval_InitThreads()
777 before using the Python API; this fix is for extension modules that
778 have no way of knowing if Python is multi-threaded yet).
779
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000780- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
781 disabled caused a crash.
782
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000783- Bug #1165306: instancemethod_new allowed the creation of a method
784 with im_class == im_self == NULL, which caused a crash when called.
785
Tim Petersecc6e6a2005-07-10 22:30:55 +0000786- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000787 fixes the crash seen in bug #1165761
788
Raymond Hettinger96229b12005-03-11 06:49:40 +0000789- Added two new builtins, any() and all().
790
Brett Cannon409d8f22005-03-05 06:47:57 +0000791- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000792 (e.g., ``class C(): pass`` is no longer a syntax error).
793 Patch #1176012 added support to the 'parser' module and 'compiler' package
794 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000795
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000796- Patch #1115086: Support PY_LONGLONG in structmember.
797
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000798- Bug #1155938: new style classes did not check that __init__() was
799 returning None.
800
Tim Petersecc6e6a2005-07-10 22:30:55 +0000801- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000802 ('\') with a specific error message.
803
Martin v. Löwisff232d72005-03-03 09:24:38 +0000804- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
805
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000806- Bug #1124295: the __name__ attribute of file objects was
807 inadvertently made inaccessible in restricted mode.
808
Tim Petersecc6e6a2005-07-10 22:30:55 +0000809- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000810 an ferror() call.
811
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000812- min() and max() now support key= arguments with the same meaning as in
813 list.sort().
814
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000815- The peephole optimizer now performs simple constant folding in expressions:
816 (2+3) --> (5).
817
Raymond Hettingera422c342005-01-11 03:03:27 +0000818- set and frozenset objects can now be marshalled. SF #1098985.
819
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000820- Bug #1077106: Poor argument checking could cause memory corruption
821 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000822
Jeremy Hyltonab630502005-02-04 18:44:06 +0000823- The parser did not complain about future statements in illegal
824 positions. It once again reports a syntax error if a future
825 statement occurs after anything other than a doc string.
826
Neil Schemenauercf52c072005-08-12 17:34:58 +0000827- Change the %s format specifier for str objects so that it returns a
828 unicode instance if the argument is not an instance of basestring and
829 calling __str__ on the argument returns a unicode instance.
830
Tim Petersf4e69282006-02-27 17:15:31 +0000831- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
832 current thread state when the auto-GIL-state machinery knows about
833 it (since the thread state is being deleted, continuing to remember it
834 can't help, but can hurt if another thread happens to get created with
835 the same thread id).
836
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000837Extension Modules
838-----------------
839
Georg Brandl43f08a82006-03-31 18:01:16 +0000840- Patch #1380952: fix SSL objects timing out on consecutive read()s
841
Neal Norwitz05a45592006-03-20 06:30:08 +0000842- Patch #1309579: wait3 and wait4 were added to the posix module.
843
Anthony Baxterfa869072006-03-20 05:21:58 +0000844- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
845 In addition, the existing ulaw code was updated.
846
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000847- RFE #567972: Socket objects' family, type and proto properties are

Georg Brandlbc45a3f2006-03-17 19:17:34 +0000849
Neal Norwitz10be10c2006-03-16 06:50:13 +0000850- Everything under lib-old was removed. This includes the following modules:
851 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000852 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000853 util, whatsound, whrandom, zmod
854
855- The following modules were removed: regsub, reconvert, regex, regex_syntax.
856
857- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000858 is deprecated. The undocumented re.engine variable no longer exists.
859
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000860- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
861 SS2 (single-shift 2) escape sequences correctly.
862
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000863- The unicodedata module was updated to the 4.1 version of the Unicode
864 database. The 3.2 version is still available as unicodedata.db_3_2_0
865 for applications that require this specific version (such as IDNA).
866
Neal Norwitzb62c4332006-03-04 18:35:47 +0000867- The timing module is no longer built by default. It was deprecated
868 in PEP 4 in Python 2.0 or earlier.
869
Guido van Rossum1968ad32006-02-25 22:38:04 +0000870- Patch 1433928: Added a new type, defaultdict, to the collections module.
871 This uses the new __missing__ hook behavior added to dict (see above).
872
Georg Brandldbd83392006-02-20 09:42:33 +0000873- Bug #854823: socketmodule now builds on Sun platforms even when
874 INET_ADDRSTRLEN is not defined.
875
Georg Brandlf4f44152006-02-18 22:29:33 +0000876- Patch #1393157: os.startfile() now has an optional argument to specify
877 a "command verb" to invoke on the file.
878
Neal Norwitz082b2df2006-02-07 07:04:46 +0000879- Bug #876637, prevent stack corruption when socket descriptor
880 is larger than FD_SETSIZE.
881
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000882- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
883 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
884 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
885
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000886- Patch #1422385: The nis module now supports access to domains other
887 than the system default domain.
888
Martin v. Löwis14694662006-02-03 12:54:16 +0000889- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
890 are reported, the limit on path name lengths is removed, and stat reports
891 WindowsError now (instead of OSError).
892
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000893- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
894
Neal Norwitz62a21122006-01-25 05:21:55 +0000895- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
896 before the env.
897
Martin v. Löwis11017b12006-01-14 18:12:57 +0000898- Patch #1103116: Basic AF_NETLINK support.
899
Neal Norwitz3b4fff82006-01-11 08:54:45 +0000900- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)
901
Neal Norwitz88bbd732006-01-10 07:05:44 +0000902- Bug #1400822, _curses over{lay,write} doesn't work when passing 6 ints.
903 Also fix ungetmouse() which did not accept arguments properly.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001024Library
1025-------
1026
Nick Coghlan43832302006-04-23 17:04:07 +00001027- PEP 338: new module runpy defines a run_module function to support
1028 executing modules which provide access to source code or a code object
1029 via the PEP 302 import mechanisms.
1030
Anthony Baxter93f5b932006-04-03 08:05:07 +00001031- The email module's parsedate_tz function now sets the daylight savings
1032 flag to -1 (unknown) since it can't tell from the date whether it should
1033 be set.
1034
Fred Drakead5177c2006-04-01 22:14:43 +00001035- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
1036 now sport attributes that provide access to the parts of the result.
1037

1039 in attribute values.
1040
Anthony Baxterc51ee692006-04-01 00:57:31 +00001041- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001042 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001043 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001044 module will not be built.
1045
Tim Petersc17976e2006-04-01 00:26:53 +00001046- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1047 aren't officially supported here, and trying to use them will probably
1048 raise an exception some day. But dicts have been allowed, and "mostly
1049 worked", so support for them won't go away without warning.
1050
Georg Brandl338ef7d2006-03-31 18:42:16 +00001051- Bug #1445068: getpass.getpass() can now be given an explicit stream
1052 argument to specify where to write the prompt.
1053
Georg Brandl22ec80b2006-03-31 18:25:44 +00001054- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1060 key to be used for signing the uploaded code.
1061
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001062- Queue.Queue objects now support .task_done() and .join() methods
1063 to make it easier to monitor when daemon threads have completed
1064 processing all enqueued tasks. Patch #1455676.
1065
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001066- popen2.Popen objects now preserve the command in a .cmd attribute.

1069
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001070- email 4.0 package now integrated. This is largely the same as the email 3.0
1071 package that was included in Python 2.3, except that PEP 8 module names are
1072 now used (e.g. mail.message instead of email.Message). The MIME classes
1073 have been moved to a subpackage (e.g. email.mime.text instead of
1074 email.MIMEText). The old names are still supported for now. Several
1075 deprecated Message methods have been removed and lots of bugs have been
1076 fixed. More details can be found in the email package documentation.
1077
Walter Dörwald40108c92006-03-27 08:15:44 +00001078- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1079 (a subclass of tuple) that provides incremental decoders and encoders
1080 (a way to use stateful codecs without the stream API). Python functions
1081 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1082 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1083 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001084
Walter Dörwald067db482006-03-15 22:17:27 +00001085- Patch #1359365: Calling next() on a closed StringIO.String object raises
1086 a ValueError instead of a StopIteration now (like file and cString.String do).
1087 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1088 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001089
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001090- A regrtest option -w was added to re-run failed tests in verbose mode.

1093 interpreter to exit.
1094
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001095- The function get_count() has been added to the gc module, and gc.collect()
1096 grew an optional 'generation' argument.
1097
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001098- A library msilib to generate Windows Installer files, and a distutils
1099 command bdist_msi have been added.
1100
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001101- PEP 343: new module contextlib.py defines decorator @contextmanager
1102 and helpful context managers nested() and closing().
1103
Martin v. Löwis415ed932006-02-27 19:56:30 +00001104- The compiler package now supports future imports after the module docstring.
1105

1107 not allowed by the specs.
1108
Georg Brandlc98eeed2006-02-19 14:57:47 +00001109- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00001138 specifications, raises IOErrors when proxies for unsupported protocols
1139 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001162 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1163 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1164 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1165 Ronald L. Rivest offered this advice for Python:
1166
1167 "The consensus of researchers in this area (at least as
1168 expressed at the NIST Hash Function Workshop 10/31/05),
1169 is that SHA-256 is a good choice for the time being, but
1170 that research should continue, and other alternatives may
1171 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001172

1226 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001227 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001228

1250 to W3C name (404 -> 'Not Found'). RFE #1216944.
1251
Georg Brandl9e43acf2005-07-04 17:16:07 +00001252- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1253 as this can cause problems with apps closing all file descriptors.

1266 Bug #1224621.
1267
Raymond Hettinger68c04532005-06-10 11:05:19 +00001268- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001269 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001270 the generate_tokens() function now accepts a callable argument that
1271 terminates by raising StopIteration.
1272
Georg Brandl9166e1a2005-06-04 09:20:03 +00001273- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1274
Georg Brandl268e61c2005-06-03 14:28:50 +00001275- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1276 component of the path.
1277
Skip Montanaro174dd222005-05-14 20:54:16 +00001278- Patch #1120353: The xmlrpclib module provides better, more transparent,

1280 to True, applications shouldn't have to fiddle with the DateTime wrapper
1281 class at all.
1282
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001283- distutils.commands.upload was added to support uploading distribution
1284 files to PyPI.
1285
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001286- distutils.commands.register now encodes the data as UTF-8 before posting
1287 them to PyPI.
1288
Raymond Hettinger267b8682005-03-27 10:47:39 +00001289- decimal operator and comparison methods now return NotImplemented
1290 instead of raising a TypeError when interacting with other types. This
1291 allows other classes to implement __radd__ style methods and have them
1292 work as expected.
1293
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001294- Bug #1163325: Decimal infinities failed to hash. Attempting to
1295 hash a NaN raised an InvalidOperation instead of a TypeError.
1296
Tim Petersecc6e6a2005-07-10 22:30:55 +00001297- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001298 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1299

1331
Guido van Rossumd0641422005-02-03 15:01:24 +00001332- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1333 disables recursive traversal through instance attributes, which can
1334 be exploited in various ways.
1335
Tim Peterse3547fd2005-12-16 23:13:57 +00001336- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001337 flags on the HTTP listening socket.
1338
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001339- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1340 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1341
Tim Peterse3547fd2005-12-16 23:13:57 +00001342- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001343 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1344
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001345- Bug #1110478: Revert os.environ.update to do putenv again.
1346
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001347- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1348
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001349- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1350
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001351- Enhancements to the csv module:
1352
1353 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001354 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001355 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001356 + Dialect parameter parsing has been re-implemented to improve error
1357 reporting.
1358 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1359 dictates.
1360 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001361 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001362 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001363 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1364 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001365 + reader now allows \r characters to be quoted (previously it only allowed
1366 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001367 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001368 + Dialect classes passed to the module are no longer instantiated by
1369 the module before being parsed (the former validation scheme required
1370 this, but the mechanism was unreliable).
1371 + The dialect registry now contains instances of the internal
1372 C-coded dialect type, rather than references to python objects.
1373 + the internal c-coded dialect type is now immutable.
1374 + register_dialect now accepts the same keyword dialect specifications
1375 as the reader and writer, allowing the user to register dialects
1376 without first creating a dialect class.
1377 + a configurable limit to the size of parsed fields has been added -
1378 previously, an unmatched quote character could result in the entire
1379 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001380 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001381 the parser field size limit (returning the former limit). The initial
1382 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001383 + A line_num attribute has been added to the reader object, which tracks
1384 the number of lines read from the source iterator. This is not
1385 the same as the number of records returned, as records can span
1386 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001387 + reader and writer objects were not being registered with the cyclic-GC.
1388 This has been fixed.
1389
Brett Cannone6539c42005-01-08 02:43:53 +00001390- _DummyThread objects in the threading module now delete self.__block that is
1391 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1392 lock primitives tend to be limited in number and thus should not be wasted on
1393 a _DummyThread object. Fixes bug #1089632.
1394
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001395- The imghdr module now detects Exif files.
1396
Raymond Hettinger6065d322004-12-20 23:51:53 +00001397- StringIO.truncate() now correctly adjusts the size attribute.
1398 (Bug #951915).
1399
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001400- locale.py now uses an updated locale alias table (built using
1401 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1402 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001403 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001404
Raymond Hettinger3557f422004-12-07 12:02:02 +00001405- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1406
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001407- the pickle module no longer accepts the deprecated None option in the
1408 args tuple returned by __reduce__().
1409
Brett Cannon84667c02004-12-07 03:25:18 +00001410- optparse now optionally imports gettext. This allows its use in setup.py.
1411
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001412- the pickle module no longer uses the deprecated bin parameter.
1413
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001414- the shelve module no longer uses the deprecated binary parameter.
1415
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001416- the pstats module no longer uses the deprecated ignore() method.
1417
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001418- the filecmp module no longer uses the deprecated use_statcache argument.
1419
Raymond Hettinger664347b2004-12-04 21:21:53 +00001420- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1421 extended or overridden by subclasses. Formerly, the subclassed method would
1422 be ignored by the rest of the module. (Bug #1078905).
1423
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001424- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001425 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001426
Walter Dörwald36733692004-12-22 12:50:50 +00001427- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1428 once when a size argument is given. This prevents a buffer overflow in the
1429 tokenizer with very long source lines.
1430
Barry Warsaw538561e2006-01-01 21:48:54 +00001431- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1432 immediately after creating the object, without any intervening
1433 ``.decompress()`` calls.

Skip Montanaro05885812005-01-16 20:48:27 +00001435- The reconvert.quote function can now emit triple-quoted strings. The
1436 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001437
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001438- ``UserString.MutableString`` now supports negative indices in
1439 ``__setitem__`` and ``__delitem__``
1440
Greg Ward40407942005-03-05 02:53:17 +00001441- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1442 correctly.
1443
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001444- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1445 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1446 character even if the user has passed a size parameter to get a proper
1447 line ending. Remove the special handling of a "\r\n" that has been split
1448 between two lines.
1449
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001450- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1451 about illegal code points. The codec now supports PEP 293 style error
1452 handlers.
1453
Walter Dörwald78a78b02005-09-01 12:04:29 +00001454- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001455 from the input stream, so that the output is a byte string in the correct
1456 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001457
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001458- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1459 considering it exactly like a '*'.
1460
Walter Dörwald007f8df2005-10-09 19:42:27 +00001461- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1462 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001463
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001464- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1465
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001466- Patch #1413711: Certain patterns of differences were making difflib
1467 touch the recursion limit.
1468
Walter Dörwald58917a62006-03-31 15:26:22 +00001469- Bug #947906: An object oriented interface has been added to the calendar
1470 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001471 called as a script (e.g. via ``python -mcalendar``). Localized month and
1472 weekday names can be ouput (even if an exotic encoding is used) using
1473 special classes that use unicode.

1476-----
1477
Neal Norwitz602d3392006-03-31 08:21:40 +00001478- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1479 by using -mieee gcc option.
1480

1482
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001483- Build support for Win64-AMD64 was added.
1484
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001485- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1486
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001487- Patch #881820: look for openpty and forkpty also in libbsd.
1488
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001489- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1490 The zlib module is now builtin on Windows.
1491
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001492- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1493
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001494- Bug #1189330: configure did not correctly determine the necessary
1495 value of LINKCC if python was built with GCC 4.0.
1496
Trent Mick8321b422005-07-26 02:29:21 +00001497- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1498 vulnerability in zlib 1.2.1 and 1.2.2.
1499
Brett Cannon08cd5982005-04-24 22:26:38 +00001500- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1501 flags that change binary compatibility. Changes were also made to
1502 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001503 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001504
Bob Ippolitoed233462005-03-29 13:47:59 +00001505- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1506 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1507 no longer exists). This configure patch makes things right.
1508
Martin v. Löwise2713be2005-03-08 15:03:08 +00001509- Bug #1158607: Build with --disable-unicode again.
1510
Brett Cannon46d96232005-02-16 00:07:19 +00001511- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1512 defined. Discovered as a result of not being able to build on OS X.
1513
Brett Cannon516592f2004-12-07 00:42:59 +00001514- setup.py now uses the directories specified in LDFLAGS using the -L option
1515 and in CPPFLAGS using the -I option for adding library and include
1516 directories, respectively, for compiling extension modules against. This has
1517 led to the core being compiled using the values in CPPFLAGS. It also removes
1518 the need for the special-casing of both DarwinPorts and Fink for darwin since
1519 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1520 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1521 Fink, ``-I/opt/local/include`` for DarwinPorts).
1522
Brett Cannon43802422005-02-10 20:48:03 +00001523- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1524 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1525 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1526 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001528C API
1529-----
1530
Tim Petersc9d78aa2006-03-26 23:27:58 +00001531- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1532 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1533 is obtained via the ``PyObject_`` family, it must be released via the
1534 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1535 always been officially true, but when Python's small-object allocator was
1536 introduced, an attempt was made to cater to a few extension modules
1537 discovered at the time that obtained memory via ``PyObject_New`` but
1538 released it via ``PyMem_DEL``. It's years later, and if such code still
1539 exists it will fail now (probably with segfaults, but calling wrong
1540 low-level memory management functions can yield many symptoms).
1541
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001542- Added a C API for set and frozenset objects.
1543
Raymond Hettinger66517482004-12-03 11:45:13 +00001544- Removed PyRange_New().
1545
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001546- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1547 mapping argument now. This string is used as a mapping table. Byte values
1548 greater than the length of the string and 0xFFFE are treated as undefined
1549 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001555- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001556
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001557- Patch #1276356: New resource "urlfetch" is implemented. This enables
1558 even impatient people to run tests that require remote files.
