Raymond Hettinger4901a1f2004-12-02 08:59:14 +00007What's New in Python 2.5 alpha 1?
8=================================
9
Anthony Baxter12b6f6c2005-03-29 13:36:16 +000010*Release date: XX-XXX-2006*
11
Raymond Hettinger4901a1f2004-12-02 08:59:14 +000012Core and builtins
13-----------------
14
Georg Brandlabd1ff82006-03-18 07:59:59 +000015- Previously, Python code had no easy way to access the contents of a
16 cell object. Now, a ``cell_contents`` attribute has been added
17 (closes patch #1170323).
18
Tim Peterscf79aac2006-03-16 01:14:46 +000019- Patch #1123430: Python's small-object allocator now returns an arena to
20 the system ``free()`` when all memory within an arena becomes unused
21 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
22 freed. Some applications will see a drop in virtual memory size now,
23 especially long-running applications that, from time to time, temporarily
24 use a large number of small objects. Note that when Python returns an
25 arena to the platform C's ``free()``, there's no guarantee that the
26 platform C will in turn return that memory to the operating system. The
27 effect of the patch is to stop making that impossible, and in tests it
28 appears to be effective at least on Microsoft C and gcc-based systems.
29 Thanks to Evan Jones for hard work and patience.
30
Georg Brandl533ff6f2006-03-08 18:09:27 +000031- Patch #1434038: property() now uses the getter's docstring if there is
32 no "doc" argument given. This makes it possible to legitimately use
33 property() as a decorator to produce a read-only property.
34
Guido van Rossum9aa37ab2006-03-07 18:54:08 +000035- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
36 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
37 of requiring an int or long in slicing and a few other contexts, enabling
38 other objects (e.g. Numeric Python's integers) to be used as slice indices.
39
Neal Norwitz995acdf2006-03-07 05:01:00 +000040- Fixed various bugs reported by Coverity's Prevent tool.
41
Brett Cannonbf364092006-03-01 04:25:17 +000042- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
43 new exception base class, BaseException, which has a new message attribute.
44 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
45 Raising a string exception now raises a DeprecationWarning.
46
Thomas Woutersfb609f42006-02-28 16:37:25 +000047- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
48 explicitly relative, using 'from .module import name' to mean 'from the same
49 package as this module is in. Imports without dots still default to the
50 old relative-then-absolute, unless 'from __future__ import
51 absolute_import' is used.
52
Brett Cannona7446e32006-02-27 23:39:10 +000053- Properly check if 'warnings' raises an exception (usually when a filter set
54 to "error" is triggered) when raising a warning for raising string
55 exceptions.
56
Neal Norwitz0023a2f2006-02-27 23:24:48 +000057- CO_GENERATOR_ALLOWED is no longer defined, this behavior is the default.
58 The name was removed from Include/code.h.
59
Neal Norwitzeb651252006-02-27 16:47:12 +000060- PEP 308: conditional expressions were added (x if cond else y).
61
Guido van Rossum1968ad32006-02-25 22:38:04 +000062- Patch 1433928:
63 - The copy module now "copies" function objects (as atomic objects).
64 - dict.__getitem__ now looks for a __missing__ hook before raising
65 KeyError.
66
Tim Peters84ef21c2006-02-28 20:39:06 +000067- PEP 343: with statement implemented. Needs ``from __future__ import
68 with_statement``. Use of 'with' as a variable will generate a warning.
69 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +000070 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +000071 The following objects have __context__ methods:
72 - The built-in file type.
73 - The thread.LockType type.
74 - The following types defined by the threading module:
75 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
76 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +000077
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +000078- Fix the encodings package codec search function to only search
79 inside its own package. Fixes problem reported in patch #1433198.
80
81 Note: Codec packages should implement and register their own
82 codec search function. PEP 100 has the details.
83
Martin v. Löwis18e16552006-02-15 17:27:45 +000084- PEP 353: Using ssize_t as the index type.
85
Neal Norwitzfc76d632006-01-10 06:03:13 +000086- Patch #1400181, fix unicode string formatting to not use the locale.
87 This is how string objects work. u'%f' could use , instead of .
88 for the decimal point. Now both strings and unicode always use periods.
89
Neal Norwitz671b9e32006-01-09 07:07:12 +000090- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
91 configure would break checking curses.h.
92
Georg Brandlcd4d1e82005-12-27 17:37:07 +000093- Bug #959576: The pwd module is now builtin. This allows Python to be
94 built on UNIX platforms without $HOME set.
95
Neal Norwitzc10978f2005-12-19 06:07:16 +000096- Bug #1072182, fix some potential problems if characters are signed.
97
Neal Norwitz5d0ad502005-12-19 04:27:42 +000098- Bug #889500, fix line number on SyntaxWarning for global declarations.
99
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000100- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
101
Neal Norwitze7214a12005-12-18 05:03:17 +0000102- Support for converting hex strings to floats no longer works.
103 This was not portable. float('0x3') now raises a ValueError.
104
Barry Warsaw2a38a862005-12-18 01:27:35 +0000105- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000106 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000107 is now displayed in interactive prompt banner.
108
Georg Brandlfa166682005-12-17 21:45:17 +0000109- Implementation of PEP 341 - Unification of try/except and try/finally.
110 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000111 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000112
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000113- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
114 now encodes backslash correctly.
115
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000116- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
117
Georg Brandlf06e30a2005-11-24 15:37:42 +0000118- Bug #1281408: Py_BuildValue now works correct even with unsigned longs
119 and long longs.
120
Neal Norwitz67715f02005-11-09 06:59:35 +0000121- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
122 It was possible dlerror() returns a NULL pointer, use a default error
123 message in this case.
124
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000125- Replaced most Unicode charmap codecs with new ones using the
126 new Unicode translate string feature in the builtin charmap
127 codec; the codecs were created from the mapping tables available
128 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
129 encodings now include a mapping for the Apple logo)
130
Tim Peterse3547fd2005-12-16 23:13:57 +0000131- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000132
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000133- Speed up some Unicode operations.
134
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000135- A new AST parser implementation was completed. The abstract
136 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000137 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000138
Neal Norwitzb6570f52005-10-21 06:26:10 +0000139- SF bug #1167751: fix incorrect code being for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000140 The following code now raises a SyntaxError: foo(a = i for i in range(10))
141
Neal Norwitz708e51a2005-10-03 04:48:15 +0000142- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
143
Neal Norwitz11bd1192005-10-03 00:54:56 +0000144- SF Bug #887946: fix segfault when redirecting stdin from a directory.
145 Provide a warning when a directory is passed on the command line.
146
Neal Norwitz40d37812005-10-02 01:48:49 +0000147- Fix segfault with invalid coding.
148
149- SF bug #772896: unknown encoding results in MemoryError.
150
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000151- All iterators now have a Boolean value of true. Formerly, some iterators
152 supported a __len__() method which evaluated to False when the iterator
153 was empty.
154
Guido van Rossum630db602005-09-20 18:49:54 +0000155- On 64-bit platforms, when __len__() returns a value that cannot be
156 represented as a C int, raise OverflowError.
157
Skip Montanarof8948ca2005-09-19 03:54:46 +0000158- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000159 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000160
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000161- SF bug #893549: parsing keyword arguments was broken with a few format
162 codes.
163
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000164- Changes donated by Elemental Security to make it work on AIX 5.3
165 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
166 bug #105470: test_pwd fails on 64bit system (Opteron).
167
Guido van Rossum539c6622005-09-14 17:49:54 +0000168- Changes donated by Elemental Security to make it work on HP-UX 11 on
169 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
170
Georg Brandl4550b8d2005-08-26 06:43:52 +0000171- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000172 (fixes bug #1119418).
173
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000174- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
175
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000176- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
177 exceptions that cause a function to exit.
178
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000179- The implementation of set() and frozenset() was revised to use its
180 own internal data structure. Memory consumption is reduced by 1/3
181 and there are modest speed-ups as well. The API is unchanged.
182
Tim Petersde7990b2005-07-17 23:45:23 +0000183- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
184
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000185- SF bug #1229429: PyObject_CallMethod failed to decrement some
186 reference counts in some error exit cases.
187
Tim Petersecc6e6a2005-07-10 22:30:55 +0000188- SF bug #1185883: Python's small-object memory allocator took over
189 a block managed by the platform C library whenever a realloc specified
190 a small new size. However, there's no portable way to know then how
191 much of the address space following the pointer is valid, so no
192 portable way to copy data from the C-managed block into Python's
193 small-object space without risking a memory fault. Python's small-object
194 realloc now leaves such blocks under the control of the platform C
195 realloc.
196
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000197- SF bug #1232517: An overflow error was not detected properly when
198 attempting to convert a large float to an int in os.utime().
199
Raymond Hettinger3296e692005-06-29 23:29:56 +0000200- SF bug #1224347: hex longs now print with lowercase letters just
201 like their int counterparts.
202
Michael W. Hudson188d4362005-06-20 16:52:57 +0000203- SF bug #1163563: the original fix for bug #1010677 ("thread Module
204 Breaks PyGILState_Ensure()") broke badly in the case of multiple
205 interpreter states; back out that fix and do a better job (see
206 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
207 for a longer write-up of the problem).
208
Michael W. Hudsondf888462005-06-03 14:41:55 +0000209- SF patch #1180995: marshal now uses a binary format by default when
210 serializing floats.
211
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000212- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
213 the routines that promise to produce IEEE 754 binary representations
214 of floats now simply copy bytes around.
215
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000216- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
217 278.
218
Brett Cannonc3647ac2005-04-26 03:45:26 +0000219- patch #1109424: int, long, float, complex, and unicode now check for the
220 proper magic slot for type conversions when subclassed. Previously the
221 magic slot was ignored during conversion. Semantics now match the way
222 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000223 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000224 PyNumber_*().
225 Thanks Walter Dörwald.
226
Barry Warsawc8d907c2005-04-19 23:43:40 +0000227- Descriptors defined in C with a PyGetSetDef structure, where the setter is
228 NULL, now raise an AttributeError when attempting to set or delete the
229 attribute. Previously a TypeError was raised, but this was inconsistent
230 with the equivalent pure-Python implementation.
231
Michael W. Hudson774479c2005-04-18 08:46:17 +0000232- It is now safe to call PyGILState_Release() before
233 PyEval_InitThreads() (note that if there is reason to believe there
234 are multiple threads around you still must call PyEval_InitThreads()
235 before using the Python API; this fix is for extension modules that
236 have no way of knowing if Python is multi-threaded yet).
237
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000238- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
239 disabled caused a crash.
240
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000241- Bug #1165306: instancemethod_new allowed the creation of a method
242 with im_class == im_self == NULL, which caused a crash when called.
243
Tim Petersecc6e6a2005-07-10 22:30:55 +0000244- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000245 fixes the crash seen in bug #1165761
246
Raymond Hettinger96229b12005-03-11 06:49:40 +0000247- Added two new builtins, any() and all().
248
Brett Cannon409d8f22005-03-05 06:47:57 +0000249- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000250 (e.g., ``class C(): pass`` is no longer a syntax error).
251 Patch #1176012 added support to the 'parser' module and 'compiler' package
252 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000253
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000254- Patch #1115086: Support PY_LONGLONG in structmember.
255
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000256- Bug #1155938: new style classes did not check that __init__() was
257 returning None.
258
Tim Petersecc6e6a2005-07-10 22:30:55 +0000259- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000260 ('\') with a specific error message.
261
Martin v. Löwisff232d72005-03-03 09:24:38 +0000262- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
263
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000264- Bug #1124295: the __name__ attribute of file objects was
265 inadvertently made inaccessible in restricted mode.
266
Tim Petersecc6e6a2005-07-10 22:30:55 +0000267- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000268 an ferror() call.
269
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000270- min() and max() now support key= arguments with the same meaning as in
271 list.sort().
272
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000273- The peephole optimizer now performs simple constant folding in expressions:
274 (2+3) --> (5).
275
Raymond Hettingera422c342005-01-11 03:03:27 +0000276- set and frozenset objects can now be marshalled. SF #1098985.
277
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000278- Bug #1077106: Poor argument checking could cause memory corruption
279 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000280
Jeremy Hyltonab630502005-02-04 18:44:06 +0000281- The parser did not complain about future statements in illegal
282 positions. It once again reports a syntax error if a future
283 statement occurs after anything other than a doc string.
284
Neil Schemenauercf52c072005-08-12 17:34:58 +0000285- Change the %s format specifier for str objects so that it returns a
286 unicode instance if the argument is not an instance of basestring and
287 calling __str__ on the argument returns a unicode instance.
288
Tim Petersf4e69282006-02-27 17:15:31 +0000289- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
290 current thread state when the auto-GIL-state machinery knows about
291 it (since the thread state is being deleted, continuing to remember it
292 can't help, but can hurt if another thread happens to get created with
293 the same thread id).

578 "The consensus of researchers in this area (at least as
579 expressed at the NIST Hash Function Workshop 10/31/05),
580 is that SHA-256 is a good choice for the time being, but
581 that research should continue, and other alternatives may
582 arise from this research. The larger SHA's also seem OK."

677 Bug #1224621.
678
Raymond Hettinger68c04532005-06-10 11:05:19 +0000679- The tokenize module has a new untokenize() function to support a full
680 roundtrip from lexed tokens back to Python sourcecode. In addition,
681 the generate_tokens() function now accepts a callable argument that

688
Skip Montanaro174dd222005-05-14 20:54:16 +0000689- Patch #1120353: The xmlrpclib module provides better, more transparent,
690 support for datetime.{datetime,date,time} objects. With use_datetime set
691 to True, applications shouldn't have to fiddle with the DateTime wrapper
692 class at all.
693
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000694- distutils.commands.upload was added to support uploading distribution

698 them to PyPI.
699
Raymond Hettinger267b8682005-03-27 10:47:39 +0000700- decimal operator and comparison methods now return NotImplemented
701 instead of raising a TypeError when interacting with other types. This
702 allows other classes to implement __radd__ style methods and have them
703 work as expected.
704
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000705- Bug #1163325: Decimal infinities failed to hash. Attempting to
706 hash a NaN raised an InvalidOperation instead of a TypeError.
707

742
Guido van Rossumd0641422005-02-03 15:01:24 +0000743- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
744 disables recursive traversal through instance attributes, which can
745 be exploited in various ways.
746
Tim Peterse3547fd2005-12-16 23:13:57 +0000747- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000748 flags on the HTTP listening socket.
749
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000750- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
751 Fixed by reading the HTTP body in chunks instead of one big socket.read().
752
Tim Peterse3547fd2005-12-16 23:13:57 +0000753- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000754 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
755

759
Martin v. Löwis22b457e2005-01-16 08:40:58 +0000760- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
761
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000762- Enhancements to the csv module:
763
764 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +0000765 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +0000766 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000767 + Dialect parameter parsing has been re-implemented to improve error
768 reporting.
769 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
770 dictates.
771 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000772 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000773 types, rather than any object than can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000774 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
775 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000776 + reader now allows \r characters to be quoted (previously it only allowed
777 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +0000778 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000779 + Dialect classes passed to the module are no longer instantiated by
780 the module before being parsed (the former validation scheme required
781 this, but the mechanism was unreliable).
782 + The dialect registry now contains instances of the internal
783 C-coded dialect type, rather than references to python objects.
784 + the internal c-coded dialect type is now immutable.
785 + register_dialect now accepts the same keyword dialect specifications
786 as the reader and writer, allowing the user to register dialects
787 without first creating a dialect class.
788 + a configurable limit to the size of parsed fields has been added -
789 previously, an unmatched quote character could result in the entire
790 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +0000791 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000792 the parser field size limit (returning the former limit). The initial
793 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +0000794 + A line_num attribute has been added to the reader object, which tracks
795 the number of lines read from the source iterator. This is not
796 the same as the number of records returned, as records can span
797 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000798 + reader and writer objects were not being registered with the cyclic-GC.
799 This has been fixed.
800
Brett Cannone6539c42005-01-08 02:43:53 +0000801- _DummyThread objects in the threading module now delete self.__block that is
802 inherited from _Thread since it uses up a lock allocated by 'thread'. The
803 lock primitives tend to be limited in number and thus should not be wasted on
804 a _DummyThread object. Fixes bug #1089632.
805
Raymond Hettinger97db05d2005-01-07 08:15:41 +0000806- The imghdr module now detects Exif files.
807
Raymond Hettinger6065d322004-12-20 23:51:53 +0000808- StringIO.truncate() now correctly adjusts the size attribute.
809 (Bug #951915).
810
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000811- locale.py now uses an updated locale alias table (built using
812 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
813 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000814 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000815
Raymond Hettinger3557f422004-12-07 12:02:02 +0000816- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
817
Raymond Hettingera6b45cc2004-12-07 07:05:57 +0000818- the pickle module no longer accepts the deprecated None option in the
819 args tuple returned by __reduce__().
820
Brett Cannon84667c02004-12-07 03:25:18 +0000821- optparse now optionally imports gettext. This allows its use in setup.py.
822
Raymond Hettinger3489cad2004-12-05 05:20:42 +0000823- the pickle module no longer uses the deprecated bin parameter.
824
Raymond Hettinger1bc82f82004-12-05 03:58:17 +0000825- the shelve module no longer uses the deprecated binary parameter.
826
Raymond Hettinger6c92d762004-12-05 03:28:00 +0000827- the pstats module no longer uses the deprecated ignore() method.
828
Raymond Hettingerf3fa9462004-12-05 01:58:09 +0000829- the filecmp module no longer uses the deprecated use_statcache argument.
830
Raymond Hettinger664347b2004-12-04 21:21:53 +0000831- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
832 extended or overridden by subclasses. Formerly, the subclassed method would
833 be ignored by the rest of the module. (Bug #1078905).
834
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000835- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000836 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000837
Walter Dörwald36733692004-12-22 12:50:50 +0000838- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
839 once when a size argument is given. This prevents a buffer overflow in the
840 tokenizer with very long source lines.
841
Barry Warsaw538561e2006-01-01 21:48:54 +0000842- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
843 immediately after creating the object, without any intervening
844 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +0000845
Skip Montanaro05885812005-01-16 20:48:27 +0000846- The reconvert.quote function can now emit triple-quoted strings. The
847 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000848
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +0000849- ``UserString.MutableString`` now supports negative indices in
850 ``__setitem__`` and ``__delitem__``
851
Greg Ward40407942005-03-05 02:53:17 +0000852- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
853 correctly.
854
Walter Dörwaldbc8e6422005-04-21 21:32:03 +0000855- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
856 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
857 character even if the user has passed a size parameter to get a proper
858 line ending. Remove the special handling of a "\r\n" that has been split
859 between two lines.
860
Walter Dörwalda47d1c02005-08-30 10:23:14 +0000861- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
862 about illegal code points. The codec now supports PEP 293 style error
863 handlers.
864
Walter Dörwald78a78b02005-09-01 12:04:29 +0000865- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +0000866 from the input stream, so that the output is a byte string in the correct
867 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +0000868
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +0000869- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
870 considering it exactly like a '*'.
871
Walter Dörwald007f8df2005-10-09 19:42:27 +0000872- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
873 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +0000874
Walter Dörwald09f0dd52005-11-21 19:10:07 +0000875- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
876
Gustavo Niemeyer548148812006-01-31 18:34:13 +0000877- Patch #1413711: Certain patterns of differences were making difflib
878 touch the recursion limit.

886
Martin v. Löwisa55e55e2006-02-11 15:55:14 +0000887- Patch #1428494: Prefer linking against ncursesw over ncurses library.
888
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +0000889- Patch #881820: look for openpty and forkpty also in libbsd.
890
Martin v. Löwis64c33dd2006-01-03 07:42:14 +0000891- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
892 The zlib module is now builtin on Windows.
893
Martin v. Löwisd5845ec2005-12-30 12:31:38 +0000894- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
895
Martin v. Löwis147fbe52005-08-07 21:09:30 +0000896- Bug #1189330: configure did not correctly determine the necessary
897 value of LINKCC if python was built with GCC 4.0.
898
Trent Mick8321b422005-07-26 02:29:21 +0000899- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
900 vulnerability in zlib 1.2.1 and 1.2.2.
901
Brett Cannon08cd5982005-04-24 22:26:38 +0000902- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
903 flags that change binary compatibility. Changes were also made to
904 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +0000905 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +0000906
Bob Ippolitoed233462005-03-29 13:47:59 +0000907- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
908 and linking has changed (prebinding is now deprecated, and libcc_dynamic
909 no longer exists). This configure patch makes things right.
910
Martin v. Löwise2713be2005-03-08 15:03:08 +0000911- Bug #1158607: Build with --disable-unicode again.
912
Brett Cannon46d96232005-02-16 00:07:19 +0000913- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
914 defined. Discovered as a result of not being able to build on OS X.
915
Brett Cannon516592f2004-12-07 00:42:59 +0000916- setup.py now uses the directories specified in LDFLAGS using the -L option
917 and in CPPFLAGS using the -I option for adding library and include
918 directories, respectively, for compiling extension modules against. This has
919 led to the core being compiled using the values in CPPFLAGS. It also removes
920 the need for the special-casing of both DarwinPorts and Fink for darwin since
921 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
922 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
923 Fink, ``-I/opt/local/include`` for DarwinPorts).
924
Brett Cannon43802422005-02-10 20:48:03 +0000925- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
926 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
927 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
928 Closes bug #1096244. Thanks Gregory Bond.

936
Walter Dörwaldd1c1e102005-10-06 20:29:57 +0000937- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
938 mapping argument now. This string is used as a mapping table. Byte values
939 greater than the length of the string and 0xFFFE are treated as undefined
940 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +0000946- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000947
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +0000948- Patch #1276356: New resource "urlfetch" is implemented. This enables
949 even impatient people to run tests that require remote files.
