Nick Coghlanc649ec52006-05-29 12:43:05 +00007What's New in Python 2.5 beta 1?
Anthony Baxter51bcb682006-04-05 14:51:42 +00008=================================
9
Nick Coghlanc649ec52006-05-29 12:43:05 +000010*Release date: XX-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Georg Brandlb7c8f542006-05-27 12:30:25 +000015- Builtin exceptions are now full-blown new-style classes instead of
16 instances pretending to be classes, which speeds up exception handling
17 by about 80% in comparison to 2.5a2.
18
Martin v. Löwisd004fc82006-05-27 08:36:52 +000019- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
20 Unicode 4.1.
21
Georg Brandlf4ef1162006-05-26 18:03:31 +000022- Patch #921466: sys.path_importer_cache is now used to cache valid and
23 invalid file paths for the built-in import machinery which leads to
24 fewer open calls on startup.
25
Tim Peters696cf432006-05-24 21:10:40 +000026- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
27 of-2 bases. The largest speedup is for inputs with about 1000 decimal
28 digits. Conversion from non-power-of-2 bases remains quadratic-time in
29 the number of input digits (it was and remains linear-time for bases
30 2, 4, 8, 16 and 32).
31
Tim Petersb713ec22006-05-23 18:45:30 +000032- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
33 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
34 an integer close to ``sys.maxint``. This was repaired by patch
35 #1335972, which also gives a nice speedup.
36
Richard Jonescebbefc2006-05-23 18:28:17 +000037- Patch #1337051: reduced size of frame objects.
38
39- PyErr_NewException now accepts a tuple of base classes as its
40 "base" parameter.
41
Richard Jones7c88dcc2006-05-23 10:37:38 +000042- Patch #876206: function call speedup by retaining allocated frame
43 objects.
44
Georg Brandl7b90e162006-05-18 07:01:27 +000045- Bug #1462152: file() now checks more thoroughly for invalid mode
46 strings and removes a possible "U" before passing the mode to the
47 C library function.
48
Neal Norwitz1004a532006-05-15 07:17:23 +000049- Patch #1488312, Fix memory alignment problem on SPARC in unicode
50
Neal Norwitz373f0a72006-05-15 07:04:36 +000051- Bug #1487966: Fix SystemError with conditional expression in assignment
52
Martin v. Löwis879768d2006-05-11 13:28:43 +000053- WindowsError now has two error code attributes: errno, which carries
54 the error values from errno.h, and winerror, which carries the error
55 values from winerror.h. Previous versions put the winerror.h values
56 (from GetLastError()) into the errno attribute.
57
Martin v. Löwis77736712006-05-04 05:51:03 +000058- Patch #1475845: Raise IndentationError for unexpected indent.
59
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000060- Patch #1479181: split open() and file() from being aliases for each other.
61
Tim Peters44bd9862006-06-01 13:49:23 +000062- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
63 methods were always silently ignored by dictionaries when comparing keys.
64 They are now passed through (except when using the C API function
65 ``PyDict_GetItem()``, whose semantics did not change).
66
67- Bug #1456209: In some obscure cases it was possible for a class with a
68 custom ``__eq__()`` method to confuse dict internals when class instances
69 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
70 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +000072Extension Modules
73-----------------
74
Nick Coghlanc649ec52006-05-29 12:43:05 +000075- Patch #1478788 (modified version): The functional extension module has
76 been renamed to _functools and a functools Python wrapper module added.
77 This provides a home for additional function related utilities that are
78 not specifically about functional programming. See PEP 309.
79
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000080- Patch #1493701: performance enhancements for struct module.
81
Georg Brandl378d5922006-05-17 14:26:50 +000082- Patch #1490224: time.altzone is now set correctly on Cygwin.
83
Georg Brandl8d3342b2006-05-16 07:38:27 +000084- Patch #1435422: zlib's compress and decompress objects now have a
85 copy() method.
86
Neal Norwitz7a5fc282006-05-15 06:48:14 +000087- On Win32, os.listdir now supports arbitrarily-long Unicode path names
88 (up to the system limit of 32K characters).
89
90- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
91 As a result, these functions now raise WindowsError instead of OSError.
92
Tim Peters7a822da2006-05-25 21:50:17 +000093- ``time.clock()`` on Win64 should use the high-performance Windows
94 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
95 Windows platforms).
96
Neal Norwitz7a5fc282006-05-15 06:48:14 +000097- Calling Tk_Init twice is refused if the first call failed as that
98 may deadlock.
99
Nick Coghlanc649ec52006-05-29 12:43:05 +0000100
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000101Library
102-------
103
Tim Petersd609b1a2006-06-02 23:22:51 +0000104- The functions in the ``pprint`` module now sort dictionaries by key
105 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
106 if and only if its display required more than one line, although that
107 wasn't documented. The new behavior increases predictability; e.g.,
108 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
109
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000110- Patch #1497027: try HTTP digest auth before basic auth in urllib2
111 (thanks for J. J. Lee).
112
Georg Brandl2b330372006-05-28 20:23:12 +0000113- Patch #1496206: improve urllib2 handling of passwords with respect to
114 default HTTP and HTTPS ports.
115
George Yoshidaf3c65de2006-05-28 16:39:09 +0000116- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
117
Bob Ippolito7298f272006-05-23 18:43:47 +0000118- Patch #1281707: speed up gzip.readline.
119
Georg Brandlb89316f2006-05-17 15:51:16 +0000120- Patch #1180296: Two new functions were added to the locale module:
121 format_string() to get the effect of "format % items" but locale-aware,
122 and currency() to format a monetary number with currency sign.
123
Georg Brandle3a25832006-05-17 14:56:04 +0000124- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
125 and several features added, such as speed and geometry control.
126
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000127- Patch #1488881: add support for external file objects in bz2 compressed
128 tarfiles.
129
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000130- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
131 stdout arguments, making it possible to redirect input and output
132 for remote debugging.
133
134- Patch #1484695: Update the tarfile module to version 0.8. This fixes
135 a couple of issues, notably handling of long file names using the
136 GNU LONGNAME extension.
137
138- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
139 new flag when ``name`` is already the name of an option flag.
140
141- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
142 package.
143
144- Patch #1472854: make the rlcompleter.Completer class usable on non-
145 UNIX platforms.
146
147- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000172What's New in Python 2.5 alpha 2?
173=================================
174
175*Release date: 27-APR-2006*
176
177Core and builtins
178-----------------
179
Thomas Heller1b046642006-04-18 18:51:06 +0000180- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
181 by converting these apis from macros into exported functions again:
182
183 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
184 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
185 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
186 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
187 PyRun_String Py_CompileString
188
Martin v. Löwis45294a92006-04-18 06:24:08 +0000189- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
190
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000191- All uses of PyStructSequence_InitType have been changed to initialize
192 the type objects only once, even if the interpreter is initialized
193 multiple times.
194
Neal Norwitz61546162006-04-14 05:20:28 +0000195- Bug #1454485, array.array('u') could crash the interpreter. This was
196 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
197 to unicode when it didn't make sense. 'u#' now requires a unicode string.
198
199- Py_UNICODE is unsigned. It was always documented as unsigned, but
200 due to a bug had a signed value in previous versions.
201
Tim Peters3a5e8b12006-04-11 01:44:07 +0000202- Patch #837242: ``id()`` of any Python object always gives a positive
203 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
204 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000205 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000206 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000207
Tim Peters3a5e8b12006-04-11 01:44:07 +0000208 def __hash__(self):
209 return id(self) # WRONG
210
211 because a hash result must be a (short) Python int but it was always
212 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000213 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000214 was always usable as a hash value before this patch. That's no longer
215 necessarily so.
216
217- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000218 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000219 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000220 #1454844)
221
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000222- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
223 involving generators that have paused outside of any ``try`` or ``with``
224 blocks. (In 2.5a1, a paused generator that was part of a reference
225 cycle could not be garbage collected, regardless of whether it was
226 paused in a ``try`` or ``with`` block.)

229-----------------
230
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000231- Patch #1191065: Fix preprocessor problems on systems where recvfrom
232 is a macro.
233
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000234- Bug #1467952: os.listdir() now correctly raises an error if readdir()
235 fails with an error condition.
236
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000237- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
238
239- Bug #1117761: bsddb.*open() no longer raises an exception when using
240 the cachesize parameter.
241
242- Bug #1149413: bsddb.*open() no longer raises an exception when using
243 a temporary db (file=None) with the 'n' flag to truncate on open.
244
245- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
246 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000247
Armin Rigoa9017c32006-04-19 11:50:27 +0000248- Patch #1062014: AF_UNIX sockets under Linux have a special
249 abstract namespace that is now fully supported.
250

252-------
253
Tim Peters711bf302006-04-25 03:31:36 +0000254- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
255 a doctest to be skipped (the code is not run, and the expected output
256 or exception is ignored).
257
Nick Coghlanda2268f2006-04-24 04:37:15 +0000258- Fixed contextlib.nested to cope with exceptions being raised and
259 caught inside exit handlers.
260
Greg Wardab05edc2006-04-23 03:47:58 +0000261- Updated optparse module to Optik 1.5.1 (allow numeric constants in
262 hex, octal, or binary; add ``append_const`` action; keep going if
263 gettext cannot be imported; added ``OptionParser.destroy()`` method;
264 added ``epilog`` for better help generation).
265
Tim Peters21fbd572006-04-21 21:18:10 +0000266- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
267 called from a thread spawned as a side effect of importing a module.
268
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000269- The pydoc module now supports documenting packages contained in
270 .zip or .egg files.
271
272- The pkgutil module now has several new utility functions, such
273 as ``walk_packages()`` to support working with packages that are either
274 in the filesystem or zip files.
275
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000276- The mailbox module can now modify and delete messages from
277 mailboxes, in addition to simply reading them. Thanks to Gregory
278 K. Johnson for writing the code, and to the 2005 Google Summer of
279 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000280
Tim Petersc7605f22006-04-17 21:12:33 +0000281- The ``__del__`` method of class ``local`` in module ``_threading_local``
282 returned before accomplishing any of its intended cleanup.
283
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000284- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000288- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
289
Anthony Baxtere29002c2006-04-12 12:07:31 +0000290- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
291 Windows. Bug #1469163.
292
Phillip J. Eby47032112006-04-11 01:07:43 +0000293- The warnings, linecache, inspect, traceback, site, and doctest modules
294 were updated to work correctly with modules imported from zipfiles or
295 via other PEP 302 __loader__ objects.
296
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000297- Patch #1467770: Reduce usage of subprocess._active to processes which

318 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000319 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000320 CXX from --with-cxx-main, see description in README.
321

Nick Coghlanda2268f2006-04-24 04:37:15 +0000333- test_contextlib now checks contextlib.nested can cope with exceptions
334 being raised and caught inside exit handlers.
335
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000336- test_cmd_line now checks operation of the -m and -c command switches
337
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000338- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
339 it separately and by hand. It also wasn't cleaning up its changes to
340 the current Decimal context.
341
Thomas Woutersabd08882006-04-26 15:53:30 +0000342- regrtest.py now has a -M option to run tests that test the new limits of
343 containers, on 64-bit architectures. Running these tests is only sensible
344 on 64-bit machines with more than two gigabytes of memory. The argument
345 passed is the maximum amount of memory for the tests to use.

354-------------
355
Tim Petersb06d28c2006-05-12 01:57:59 +0000356- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
357
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000358- PEP 343: Added Context Types section to the library reference
359 and attempted to bring other PEP 343 related documentation into
360 line with the implementation and/or python-dev discussions.
361
Tim Peters8dc73d22006-04-24 02:03:16 +0000362- Bug #1337990: clarified that ``doctest`` does not support examples
363 requiring both expected output and an exception.

368
Anthony Baxterebed3f62006-04-03 15:03:44 +0000369*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000370
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000371Core and builtins
372-----------------
373
Nick Coghlan43832302006-04-23 17:04:07 +0000374- PEP 338: -m command line switch now delegates to runpy.run_module
375 allowing it to support modules in packages and zipfiles
376
Martin v. Löwisc661b882006-04-20 04:54:23 +0000377- On Windows, .DLL is not an accepted file name extension for
378 extension modules anymore; extensions are only found if they
379 end in .PYD.
380
Martin v. Löwisea62d252006-04-03 10:56:49 +0000381- Bug #1421664: sys.stderr.encoding is now set to the same value as
382 sys.stdout.encoding.
383
Neal Norwitz92e212f2006-04-03 04:48:37 +0000384- __import__ accepts keyword arguments.
385
Georg Brandlccadf842006-03-31 18:54:53 +0000386- Patch #1460496: round() now accepts keyword arguments.
387
Anthony Baxter262c00a2006-03-30 10:53:17 +0000388- Fixed bug #1459029 - unicode reprs were double-escaped.
389
Hye-Shik Changd478f342006-03-23 12:32:36 +0000390- Patch #1396919: The system scope threads are reenabled on FreeBSD
391 5.4 and later versions.
392
Neal Norwitze98ccf62006-03-23 05:39:47 +0000393- Bug #1115379: Compiling a Unicode string with an encoding declaration
394 now gives a SyntaxError.
395
Georg Brandlabd1ff82006-03-18 07:59:59 +0000396- Previously, Python code had no easy way to access the contents of a
397 cell object. Now, a ``cell_contents`` attribute has been added
398 (closes patch #1170323).
399
Tim Peterscf79aac2006-03-16 01:14:46 +0000400- Patch #1123430: Python's small-object allocator now returns an arena to
401 the system ``free()`` when all memory within an arena becomes unused
402 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
403 freed. Some applications will see a drop in virtual memory size now,
404 especially long-running applications that, from time to time, temporarily
405 use a large number of small objects. Note that when Python returns an
406 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000407 platform C library will in turn return that memory to the operating system.
408 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000409 appears to be effective at least on Microsoft C and gcc-based systems.
410 Thanks to Evan Jones for hard work and patience.
411
Georg Brandl533ff6f2006-03-08 18:09:27 +0000412- Patch #1434038: property() now uses the getter's docstring if there is
413 no "doc" argument given. This makes it possible to legitimately use
414 property() as a decorator to produce a read-only property.
415
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000416- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
417 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
418 of requiring an int or long in slicing and a few other contexts, enabling
419 other objects (e.g. Numeric Python's integers) to be used as slice indices.
420
Neal Norwitz995acdf2006-03-07 05:01:00 +0000421- Fixed various bugs reported by Coverity's Prevent tool.
422
Brett Cannonbf364092006-03-01 04:25:17 +0000423- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
424 new exception base class, BaseException, which has a new message attribute.
425 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
426 Raising a string exception now raises a DeprecationWarning.
427
Thomas Woutersfb609f42006-02-28 16:37:25 +0000428- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
429 explicitly relative, using 'from .module import name' to mean 'from the same
430 package as this module is in. Imports without dots still default to the
431 old relative-then-absolute, unless 'from __future__ import
432 absolute_import' is used.
433
Brett Cannona7446e32006-02-27 23:39:10 +0000434- Properly check if 'warnings' raises an exception (usually when a filter set
435 to "error" is triggered) when raising a warning for raising string
436 exceptions.
437
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000438- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000439 The name was removed from Include/code.h.
440
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000441- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000442
Guido van Rossum1968ad32006-02-25 22:38:04 +0000443- Patch 1433928:
444 - The copy module now "copies" function objects (as atomic objects).
445 - dict.__getitem__ now looks for a __missing__ hook before raising
446 KeyError.
447
Tim Peters84ef21c2006-02-28 20:39:06 +0000448- PEP 343: with statement implemented. Needs ``from __future__ import
449 with_statement``. Use of 'with' as a variable will generate a warning.
450 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000451 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000452 The following objects have __context__ methods:
453 - The built-in file type.
454 - The thread.LockType type.
455 - The following types defined by the threading module:
456 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
457 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000458
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000459- Fix the encodings package codec search function to only search
460 inside its own package. Fixes problem reported in patch #1433198.
461
462 Note: Codec packages should implement and register their own
463 codec search function. PEP 100 has the details.
464
Martin v. Löwis18e16552006-02-15 17:27:45 +0000465- PEP 353: Using ssize_t as the index type.
466
Neal Norwitzfc76d632006-01-10 06:03:13 +0000467- Patch #1400181, fix unicode string formatting to not use the locale.
468 This is how string objects work. u'%f' could use , instead of .
469 for the decimal point. Now both strings and unicode always use periods.
470
Neal Norwitz671b9e32006-01-09 07:07:12 +0000471- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
472 configure would break checking curses.h.
473
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000474- Bug #959576: The pwd module is now builtin. This allows Python to be
475 built on UNIX platforms without $HOME set.
476
Neal Norwitzc10978f2005-12-19 06:07:16 +0000477- Bug #1072182, fix some potential problems if characters are signed.
478
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000479- Bug #889500, fix line number on SyntaxWarning for global declarations.
480
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000481- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
482
Neal Norwitze7214a12005-12-18 05:03:17 +0000483- Support for converting hex strings to floats no longer works.
484 This was not portable. float('0x3') now raises a ValueError.
485
Barry Warsaw2a38a862005-12-18 01:27:35 +0000486- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000487 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000488 is now displayed in interactive prompt banner.
489
Georg Brandlfa166682005-12-17 21:45:17 +0000490- Implementation of PEP 341 - Unification of try/except and try/finally.
491 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000492 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000493
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000494- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
495 now encodes backslash correctly.
496
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000497- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
498
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000499- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000500 and long longs.
501
Neal Norwitz67715f02005-11-09 06:59:35 +0000502- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000503 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000504 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000505
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000506- Replaced most Unicode charmap codecs with new ones using the
507 new Unicode translate string feature in the builtin charmap
508 codec; the codecs were created from the mapping tables available
509 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
510 encodings now include a mapping for the Apple logo)
511
Tim Peterse3547fd2005-12-16 23:13:57 +0000512- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000513
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000514- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000515
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000516- A new AST parser implementation was completed. The abstract
517 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000518 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000519
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000520- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000521 The following code now raises a SyntaxError: foo(a = i for i in range(10))
522
Neal Norwitz708e51a2005-10-03 04:48:15 +0000523- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
524
Neal Norwitz11bd1192005-10-03 00:54:56 +0000525- SF Bug #887946: fix segfault when redirecting stdin from a directory.
526 Provide a warning when a directory is passed on the command line.
527
Neal Norwitz40d37812005-10-02 01:48:49 +0000528- Fix segfault with invalid coding.
529
530- SF bug #772896: unknown encoding results in MemoryError.
531
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000532- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000533 supported a __len__() method which evaluated to False when the iterator
534 was empty.
535
Guido van Rossum630db602005-09-20 18:49:54 +0000536- On 64-bit platforms, when __len__() returns a value that cannot be
537 represented as a C int, raise OverflowError.
538
Skip Montanarof8948ca2005-09-19 03:54:46 +0000539- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000540 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000541
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000542- SF bug #893549: parsing keyword arguments was broken with a few format
543 codes.
544
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000545- Changes donated by Elemental Security to make it work on AIX 5.3
546 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
547 bug #105470: test_pwd fails on 64bit system (Opteron).
548
Guido van Rossum539c6622005-09-14 17:49:54 +0000549- Changes donated by Elemental Security to make it work on HP-UX 11 on
550 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
551
Georg Brandl4550b8d2005-08-26 06:43:52 +0000552- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000553 (fixes bug #1119418).
554
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000555- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
556
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000557- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
558 exceptions that cause a function to exit.
559
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000560- The implementation of set() and frozenset() was revised to use its
561 own internal data structure. Memory consumption is reduced by 1/3
562 and there are modest speed-ups as well. The API is unchanged.
563
Tim Petersde7990b2005-07-17 23:45:23 +0000564- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
565
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000566- SF bug #1229429: PyObject_CallMethod failed to decrement some
567 reference counts in some error exit cases.
568
Tim Petersecc6e6a2005-07-10 22:30:55 +0000569- SF bug #1185883: Python's small-object memory allocator took over
570 a block managed by the platform C library whenever a realloc specified
571 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000572 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000573 portable way to copy data from the C-managed block into Python's
574 small-object space without risking a memory fault. Python's small-object
575 realloc now leaves such blocks under the control of the platform C
576 realloc.
577
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000578- SF bug #1232517: An overflow error was not detected properly when
579 attempting to convert a large float to an int in os.utime().
580
Raymond Hettinger3296e692005-06-29 23:29:56 +0000581- SF bug #1224347: hex longs now print with lowercase letters just
582 like their int counterparts.
583
Michael W. Hudson188d4362005-06-20 16:52:57 +0000584- SF bug #1163563: the original fix for bug #1010677 ("thread Module
585 Breaks PyGILState_Ensure()") broke badly in the case of multiple
586 interpreter states; back out that fix and do a better job (see
587 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
588 for a longer write-up of the problem).
589
Michael W. Hudsondf888462005-06-03 14:41:55 +0000590- SF patch #1180995: marshal now uses a binary format by default when
591 serializing floats.
592
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000593- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
594 the routines that promise to produce IEEE 754 binary representations
595 of floats now simply copy bytes around.
596
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000597- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
598 278.
599
Brett Cannonc3647ac2005-04-26 03:45:26 +0000600- patch #1109424: int, long, float, complex, and unicode now check for the
601 proper magic slot for type conversions when subclassed. Previously the
602 magic slot was ignored during conversion. Semantics now match the way
603 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000604 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000605 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000606 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000607
Barry Warsawc8d907c2005-04-19 23:43:40 +0000608- Descriptors defined in C with a PyGetSetDef structure, where the setter is
609 NULL, now raise an AttributeError when attempting to set or delete the
610 attribute. Previously a TypeError was raised, but this was inconsistent
611 with the equivalent pure-Python implementation.
612
Michael W. Hudson774479c2005-04-18 08:46:17 +0000613- It is now safe to call PyGILState_Release() before
614 PyEval_InitThreads() (note that if there is reason to believe there
615 are multiple threads around you still must call PyEval_InitThreads()
616 before using the Python API; this fix is for extension modules that
617 have no way of knowing if Python is multi-threaded yet).
618
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000619- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
620 disabled caused a crash.
621
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000622- Bug #1165306: instancemethod_new allowed the creation of a method
623 with im_class == im_self == NULL, which caused a crash when called.
624
Tim Petersecc6e6a2005-07-10 22:30:55 +0000625- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000626 fixes the crash seen in bug #1165761
627
Raymond Hettinger96229b12005-03-11 06:49:40 +0000628- Added two new builtins, any() and all().
629
Brett Cannon409d8f22005-03-05 06:47:57 +0000630- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000631 (e.g., ``class C(): pass`` is no longer a syntax error).
632 Patch #1176012 added support to the 'parser' module and 'compiler' package
633 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000634

638 returning None.
639
Tim Petersecc6e6a2005-07-10 22:30:55 +0000640- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000641 ('\') with a specific error message.
642
Martin v. Löwisff232d72005-03-03 09:24:38 +0000643- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
644
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000645- Bug #1124295: the __name__ attribute of file objects was
646 inadvertently made inaccessible in restricted mode.
647
Tim Petersecc6e6a2005-07-10 22:30:55 +0000648- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000649 an ferror() call.
650
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000651- min() and max() now support key= arguments with the same meaning as in
652 list.sort().
653
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000654- The peephole optimizer now performs simple constant folding in expressions:
655 (2+3) --> (5).
656
Raymond Hettingera422c342005-01-11 03:03:27 +0000657- set and frozenset objects can now be marshalled. SF #1098985.
658
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000659- Bug #1077106: Poor argument checking could cause memory corruption
660 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000661
Jeremy Hyltonab630502005-02-04 18:44:06 +0000662- The parser did not complain about future statements in illegal
663 positions. It once again reports a syntax error if a future
664 statement occurs after anything other than a doc string.
665
Neil Schemenauercf52c072005-08-12 17:34:58 +0000666- Change the %s format specifier for str objects so that it returns a
667 unicode instance if the argument is not an instance of basestring and
668 calling __str__ on the argument returns a unicode instance.
669
Tim Petersf4e69282006-02-27 17:15:31 +0000670- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
671 current thread state when the auto-GIL-state machinery knows about
672 it (since the thread state is being deleted, continuing to remember it
673 can't help, but can hurt if another thread happens to get created with
674 the same thread id).

705
Neal Norwitzb62c4332006-03-04 18:35:47 +0000706- The timing module is no longer built by default. It was deprecated

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000863Library
864-------
865
Nick Coghlan43832302006-04-23 17:04:07 +0000866- PEP 338: new module runpy defines a run_module function to support
867 executing modules which provide access to source code or a code object
868 via the PEP 302 import mechanisms.
869
Anthony Baxter93f5b932006-04-03 08:05:07 +0000870- The email module's parsedate_tz function now sets the daylight savings
871 flag to -1 (unknown) since it can't tell from the date whether it should
872 be set.

878 in attribute values.
879
Anthony Baxterc51ee692006-04-01 00:57:31 +0000880- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000881 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000882 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000883 module will not be built.
884
Tim Petersc17976e2006-04-01 00:26:53 +0000885- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
886 aren't officially supported here, and trying to use them will probably
887 raise an exception some day. But dicts have been allowed, and "mostly

Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000909- email 4.0 package now integrated. This is largely the same as the email 3.0
910 package that was included in Python 2.3, except that PEP 8 module names are
911 now used (e.g. mail.message instead of email.Message). The MIME classes
912 have been moved to a subpackage (e.g. email.mime.text instead of
913 email.MIMEText). The old names are still supported for now. Several
914 deprecated Message methods have been removed and lots of bugs have been
915 fixed. More details can be found in the email package documentation.
916
Walter Dörwald40108c92006-03-27 08:15:44 +0000917- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
918 (a subclass of tuple) that provides incremental decoders and encoders
919 (a way to use stateful codecs without the stream API). Python functions
920 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
921 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
922 have been added.

925 a ValueError instead of a StopIteration now (like file and cString.String do).
926 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been

1003 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1004 Ronald L. Rivest offered this advice for Python:
1005
1006 "The consensus of researchers in this area (at least as
1007 expressed at the NIST Hash Function Workshop 10/31/05),
1008 is that SHA-256 is a good choice for the time being, but
1009 that research should continue, and other alternatives may
1010 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001011

1168
Raymond Hettingerbab41432005-02-05 01:31:19 +00001169- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1170
Guido van Rossumd0641422005-02-03 15:01:24 +00001171- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1172 disables recursive traversal through instance attributes, which can
1173 be exploited in various ways.
1174
Tim Peterse3547fd2005-12-16 23:13:57 +00001175- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001176 flags on the HTTP listening socket.
1177
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001178- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1179 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1180
Tim Peterse3547fd2005-12-16 23:13:57 +00001181- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001182 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1183

1187
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001188- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1189
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001190- Enhancements to the csv module:
1191
1192 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001193 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001194 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001195 + Dialect parameter parsing has been re-implemented to improve error
1196 reporting.
1197 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1198 dictates.
1199 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001200 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001201 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001202 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1203 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001204 + reader now allows \r characters to be quoted (previously it only allowed
1205 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001206 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001207 + Dialect classes passed to the module are no longer instantiated by
1208 the module before being parsed (the former validation scheme required
1209 this, but the mechanism was unreliable).
1210 + The dialect registry now contains instances of the internal
1211 C-coded dialect type, rather than references to python objects.
1212 + the internal c-coded dialect type is now immutable.
1213 + register_dialect now accepts the same keyword dialect specifications
1214 as the reader and writer, allowing the user to register dialects
1215 without first creating a dialect class.
1216 + a configurable limit to the size of parsed fields has been added -
1217 previously, an unmatched quote character could result in the entire
1218 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001219 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001220 the parser field size limit (returning the former limit). The initial
1221 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001222 + A line_num attribute has been added to the reader object, which tracks
1223 the number of lines read from the source iterator. This is not
1224 the same as the number of records returned, as records can span
1225 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001226 + reader and writer objects were not being registered with the cyclic-GC.
1227 This has been fixed.
1228
Brett Cannone6539c42005-01-08 02:43:53 +00001229- _DummyThread objects in the threading module now delete self.__block that is
1230 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1231 lock primitives tend to be limited in number and thus should not be wasted on
1232 a _DummyThread object. Fixes bug #1089632.
1233
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001234- The imghdr module now detects Exif files.
1235
Raymond Hettinger6065d322004-12-20 23:51:53 +00001236- StringIO.truncate() now correctly adjusts the size attribute.
1237 (Bug #951915).
1238
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001239- locale.py now uses an updated locale alias table (built using
1240 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1241 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001242 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001243
Raymond Hettinger3557f422004-12-07 12:02:02 +00001244- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1245
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001246- the pickle module no longer accepts the deprecated None option in the
1247 args tuple returned by __reduce__().
1248
Brett Cannon84667c02004-12-07 03:25:18 +00001249- optparse now optionally imports gettext. This allows its use in setup.py.
1250
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001251- the pickle module no longer uses the deprecated bin parameter.
1252
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001253- the shelve module no longer uses the deprecated binary parameter.
1254
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001255- the pstats module no longer uses the deprecated ignore() method.
1256
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001257- the filecmp module no longer uses the deprecated use_statcache argument.
1258
Raymond Hettinger664347b2004-12-04 21:21:53 +00001259- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1260 extended or overridden by subclasses. Formerly, the subclassed method would
1261 be ignored by the rest of the module. (Bug #1078905).
1262
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001263- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001264 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001265
Walter Dörwald36733692004-12-22 12:50:50 +00001266- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1267 once when a size argument is given. This prevents a buffer overflow in the
1268 tokenizer with very long source lines.
1269
Barry Warsaw538561e2006-01-01 21:48:54 +00001270- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1271 immediately after creating the object, without any intervening
1272 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001273
Skip Montanaro05885812005-01-16 20:48:27 +00001274- The reconvert.quote function can now emit triple-quoted strings. The
1275 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001276
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001277- ``UserString.MutableString`` now supports negative indices in
1278 ``__setitem__`` and ``__delitem__``
1279
Greg Ward40407942005-03-05 02:53:17 +00001280- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1281 correctly.
1282
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001283- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1284 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1285 character even if the user has passed a size parameter to get a proper
1286 line ending. Remove the special handling of a "\r\n" that has been split
1287 between two lines.
1288
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001289- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1290 about illegal code points. The codec now supports PEP 293 style error
1291 handlers.
1292
Walter Dörwald78a78b02005-09-01 12:04:29 +00001293- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001294 from the input stream, so that the output is a byte string in the correct
1295 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001296
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001297- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1298 considering it exactly like a '*'.
1299
Walter Dörwald007f8df2005-10-09 19:42:27 +00001300- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1301 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001302
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001303- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1304
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001305- Patch #1413711: Certain patterns of differences were making difflib
1306 touch the recursion limit.
1307
Walter Dörwald58917a62006-03-31 15:26:22 +00001308- Bug #947906: An object oriented interface has been added to the calendar
1309 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001310 called as a script (e.g. via ``python -mcalendar``). Localized month and
1311 weekday names can be ouput (even if an exotic encoding is used) using
1312 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001313
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001314Build
1315-----
1316
Neal Norwitz602d3392006-03-31 08:21:40 +00001317- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1318 by using -mieee gcc option.
1319

1321
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001322- Build support for Win64-AMD64 was added.
1323
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001324- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1325
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001326- Patch #881820: look for openpty and forkpty also in libbsd.
1327
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001328- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1329 The zlib module is now builtin on Windows.
1330
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001331- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1332
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001333- Bug #1189330: configure did not correctly determine the necessary
1334 value of LINKCC if python was built with GCC 4.0.
1335
Trent Mick8321b422005-07-26 02:29:21 +00001336- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1337 vulnerability in zlib 1.2.1 and 1.2.2.
1338
Brett Cannon08cd5982005-04-24 22:26:38 +00001339- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1340 flags that change binary compatibility. Changes were also made to
1341 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001342 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001343
Bob Ippolitoed233462005-03-29 13:47:59 +00001344- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1345 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1346 no longer exists). This configure patch makes things right.
1347
Martin v. Löwise2713be2005-03-08 15:03:08 +00001348- Bug #1158607: Build with --disable-unicode again.
1349
Brett Cannon46d96232005-02-16 00:07:19 +00001350- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1351 defined. Discovered as a result of not being able to build on OS X.
1352
Brett Cannon516592f2004-12-07 00:42:59 +00001353- setup.py now uses the directories specified in LDFLAGS using the -L option
1354 and in CPPFLAGS using the -I option for adding library and include
1355 directories, respectively, for compiling extension modules against. This has
1356 led to the core being compiled using the values in CPPFLAGS. It also removes
1357 the need for the special-casing of both DarwinPorts and Fink for darwin since
1358 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1359 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1360 Fink, ``-I/opt/local/include`` for DarwinPorts).
1361
Brett Cannon43802422005-02-10 20:48:03 +00001362- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1363 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1364 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1365 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001367C API
1368-----
1369
Tim Petersc9d78aa2006-03-26 23:27:58 +00001370- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1371 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1372 is obtained via the ``PyObject_`` family, it must be released via the
1373 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1374 always been officially true, but when Python's small-object allocator was
1375 introduced, an attempt was made to cater to a few extension modules
1376 discovered at the time that obtained memory via ``PyObject_New`` but
1377 released it via ``PyMem_DEL``. It's years later, and if such code still
1378 exists it will fail now (probably with segfaults, but calling wrong
1379 low-level memory management functions can yield many symptoms).
1380
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001381- Added a C API for set and frozenset objects.
1382
Raymond Hettinger66517482004-12-03 11:45:13 +00001383- Removed PyRange_New().
1384
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001385- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1386 mapping argument now. This string is used as a mapping table. Byte values
1387 greater than the length of the string and 0xFFFE are treated as undefined
1388 mappings.
