Anthony Baxter82201742006-04-09 15:07:40 +000015- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
16 to load extension modules and now provides the dl module. As a result,
17 sys.setdlopenflags() now works correctly on these systems. (SF patch
18 #1454844)

Raymond Hettinger4901a1f2004-12-02 08:59:14 +000054Core and builtins
55-----------------
56
Martin v. Löwisea62d252006-04-03 10:56:49 +000057- Bug #1421664: sys.stderr.encoding is now set to the same value as
58 sys.stdout.encoding.
59
Neal Norwitz92e212f2006-04-03 04:48:37 +000060- __import__ accepts keyword arguments.
61
Georg Brandlccadf842006-03-31 18:54:53 +000062- Patch #1460496: round() now accepts keyword arguments.
63
Anthony Baxter262c00a2006-03-30 10:53:17 +000064- Fixed bug #1459029 - unicode reprs were double-escaped.
65
Hye-Shik Changd478f342006-03-23 12:32:36 +000066- Patch #1396919: The system scope threads are reenabled on FreeBSD
67 5.4 and later versions.
68
Neal Norwitze98ccf62006-03-23 05:39:47 +000069- Bug #1115379: Compiling a Unicode string with an encoding declaration
70 now gives a SyntaxError.
71
Georg Brandlabd1ff82006-03-18 07:59:59 +000072- Previously, Python code had no easy way to access the contents of a
73 cell object. Now, a ``cell_contents`` attribute has been added
74 (closes patch #1170323).
75
Tim Peterscf79aac2006-03-16 01:14:46 +000076- Patch #1123430: Python's small-object allocator now returns an arena to
77 the system ``free()`` when all memory within an arena becomes unused
78 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
79 freed. Some applications will see a drop in virtual memory size now,
80 especially long-running applications that, from time to time, temporarily
81 use a large number of small objects. Note that when Python returns an
82 arena to the platform C's ``free()``, there's no guarantee that the
83 platform C will in turn return that memory to the operating system. The
84 effect of the patch is to stop making that impossible, and in tests it
85 appears to be effective at least on Microsoft C and gcc-based systems.
86 Thanks to Evan Jones for hard work and patience.
87
Georg Brandl533ff6f2006-03-08 18:09:27 +000088- Patch #1434038: property() now uses the getter's docstring if there is
89 no "doc" argument given. This makes it possible to legitimately use
90 property() as a decorator to produce a read-only property.
91
Guido van Rossum9aa37ab2006-03-07 18:54:08 +000092- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
93 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
94 of requiring an int or long in slicing and a few other contexts, enabling
95 other objects (e.g. Numeric Python's integers) to be used as slice indices.
96
Neal Norwitz995acdf2006-03-07 05:01:00 +000097- Fixed various bugs reported by Coverity's Prevent tool.
98
Brett Cannonbf364092006-03-01 04:25:17 +000099- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
100 new exception base class, BaseException, which has a new message attribute.
101 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
102 Raising a string exception now raises a DeprecationWarning.
103
Thomas Woutersfb609f42006-02-28 16:37:25 +0000104- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
105 explicitly relative, using 'from .module import name' to mean 'from the same
106 package as this module is in. Imports without dots still default to the
107 old relative-then-absolute, unless 'from __future__ import
108 absolute_import' is used.
109
Brett Cannona7446e32006-02-27 23:39:10 +0000110- Properly check if 'warnings' raises an exception (usually when a filter set
111 to "error" is triggered) when raising a warning for raising string
112 exceptions.
113
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000114- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000115 The name was removed from Include/code.h.
116
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000117- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000118
Guido van Rossum1968ad32006-02-25 22:38:04 +0000119- Patch 1433928:
120 - The copy module now "copies" function objects (as atomic objects).
121 - dict.__getitem__ now looks for a __missing__ hook before raising
122 KeyError.
123
Tim Peters84ef21c2006-02-28 20:39:06 +0000124- PEP 343: with statement implemented. Needs ``from __future__ import
125 with_statement``. Use of 'with' as a variable will generate a warning.
126 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000127 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000128 The following objects have __context__ methods:
129 - The built-in file type.
130 - The thread.LockType type.
131 - The following types defined by the threading module:
132 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
133 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000134
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000135- Fix the encodings package codec search function to only search
136 inside its own package. Fixes problem reported in patch #1433198.
137
138 Note: Codec packages should implement and register their own
139 codec search function. PEP 100 has the details.
140
Martin v. Löwis18e16552006-02-15 17:27:45 +0000141- PEP 353: Using ssize_t as the index type.
142
Neal Norwitzfc76d632006-01-10 06:03:13 +0000143- Patch #1400181, fix unicode string formatting to not use the locale.
144 This is how string objects work. u'%f' could use , instead of .
145 for the decimal point. Now both strings and unicode always use periods.
146
Neal Norwitz671b9e32006-01-09 07:07:12 +0000147- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
148 configure would break checking curses.h.
149
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000150- Bug #959576: The pwd module is now builtin. This allows Python to be
151 built on UNIX platforms without $HOME set.
152
Neal Norwitzc10978f2005-12-19 06:07:16 +0000153- Bug #1072182, fix some potential problems if characters are signed.
154
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000155- Bug #889500, fix line number on SyntaxWarning for global declarations.
156
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000157- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
158
Neal Norwitze7214a12005-12-18 05:03:17 +0000159- Support for converting hex strings to floats no longer works.
160 This was not portable. float('0x3') now raises a ValueError.
161
Barry Warsaw2a38a862005-12-18 01:27:35 +0000162- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000163 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000164 is now displayed in interactive prompt banner.
165
Georg Brandlfa166682005-12-17 21:45:17 +0000166- Implementation of PEP 341 - Unification of try/except and try/finally.
167 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000168 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000169
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000170- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
171 now encodes backslash correctly.
172
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000173- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
174
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000175- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000176 and long longs.
177
Neal Norwitz67715f02005-11-09 06:59:35 +0000178- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000179 It was possible for dlerror() to return a NULL pointer, so
180 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000181
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000182- Replaced most Unicode charmap codecs with new ones using the
183 new Unicode translate string feature in the builtin charmap
184 codec; the codecs were created from the mapping tables available
185 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
186 encodings now include a mapping for the Apple logo)
187
Tim Peterse3547fd2005-12-16 23:13:57 +0000188- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000189
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000190- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000191
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000192- A new AST parser implementation was completed. The abstract
193 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000194 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000195
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000196- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000197 The following code now raises a SyntaxError: foo(a = i for i in range(10))
198
Neal Norwitz708e51a2005-10-03 04:48:15 +0000199- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
200
Neal Norwitz11bd1192005-10-03 00:54:56 +0000201- SF Bug #887946: fix segfault when redirecting stdin from a directory.
202 Provide a warning when a directory is passed on the command line.
203
Neal Norwitz40d37812005-10-02 01:48:49 +0000204- Fix segfault with invalid coding.
205
206- SF bug #772896: unknown encoding results in MemoryError.
207
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000208- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000209 supported a __len__() method which evaluated to False when the iterator
210 was empty.
211
Guido van Rossum630db602005-09-20 18:49:54 +0000212- On 64-bit platforms, when __len__() returns a value that cannot be
213 represented as a C int, raise OverflowError.
214
Skip Montanarof8948ca2005-09-19 03:54:46 +0000215- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000216 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000217
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000218- SF bug #893549: parsing keyword arguments was broken with a few format
219 codes.
220
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000221- Changes donated by Elemental Security to make it work on AIX 5.3
222 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
223 bug #105470: test_pwd fails on 64bit system (Opteron).
224
Guido van Rossum539c6622005-09-14 17:49:54 +0000225- Changes donated by Elemental Security to make it work on HP-UX 11 on
226 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
227
Georg Brandl4550b8d2005-08-26 06:43:52 +0000228- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000229 (fixes bug #1119418).
230
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000231- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
232
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000233- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
234 exceptions that cause a function to exit.
235
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000236- The implementation of set() and frozenset() was revised to use its
237 own internal data structure. Memory consumption is reduced by 1/3
238 and there are modest speed-ups as well. The API is unchanged.
239
Tim Petersde7990b2005-07-17 23:45:23 +0000240- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
241
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000242- SF bug #1229429: PyObject_CallMethod failed to decrement some
243 reference counts in some error exit cases.
244
Tim Petersecc6e6a2005-07-10 22:30:55 +0000245- SF bug #1185883: Python's small-object memory allocator took over
246 a block managed by the platform C library whenever a realloc specified
247 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000248 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000249 portable way to copy data from the C-managed block into Python's
250 small-object space without risking a memory fault. Python's small-object
251 realloc now leaves such blocks under the control of the platform C
252 realloc.
253
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000254- SF bug #1232517: An overflow error was not detected properly when
255 attempting to convert a large float to an int in os.utime().
256
Raymond Hettinger3296e692005-06-29 23:29:56 +0000257- SF bug #1224347: hex longs now print with lowercase letters just
258 like their int counterparts.
259
Michael W. Hudson188d4362005-06-20 16:52:57 +0000260- SF bug #1163563: the original fix for bug #1010677 ("thread Module
261 Breaks PyGILState_Ensure()") broke badly in the case of multiple
262 interpreter states; back out that fix and do a better job (see
263 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
264 for a longer write-up of the problem).
265
Michael W. Hudsondf888462005-06-03 14:41:55 +0000266- SF patch #1180995: marshal now uses a binary format by default when
267 serializing floats.
268
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000269- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
270 the routines that promise to produce IEEE 754 binary representations
271 of floats now simply copy bytes around.
272
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000273- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
274 278.
275
Brett Cannonc3647ac2005-04-26 03:45:26 +0000276- patch #1109424: int, long, float, complex, and unicode now check for the
277 proper magic slot for type conversions when subclassed. Previously the
278 magic slot was ignored during conversion. Semantics now match the way
279 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000280 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000281 PyNumber_*().
282 Thanks Walter Dörwald.
283
Barry Warsawc8d907c2005-04-19 23:43:40 +0000284- Descriptors defined in C with a PyGetSetDef structure, where the setter is
285 NULL, now raise an AttributeError when attempting to set or delete the
286 attribute. Previously a TypeError was raised, but this was inconsistent
287 with the equivalent pure-Python implementation.
288
Michael W. Hudson774479c2005-04-18 08:46:17 +0000289- It is now safe to call PyGILState_Release() before
290 PyEval_InitThreads() (note that if there is reason to believe there
291 are multiple threads around you still must call PyEval_InitThreads()
292 before using the Python API; this fix is for extension modules that
293 have no way of knowing if Python is multi-threaded yet).
294
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000295- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
296 disabled caused a crash.
297
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000298- Bug #1165306: instancemethod_new allowed the creation of a method
299 with im_class == im_self == NULL, which caused a crash when called.

Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000325 an ferror() call.
326
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000327- min() and max() now support key= arguments with the same meaning as in

Jeremy Hyltonab630502005-02-04 18:44:06 +0000338- The parser did not complain about future statements in illegal

340 statement occurs after anything other than a doc string.
341
Neil Schemenauercf52c072005-08-12 17:34:58 +0000342- Change the %s format specifier for str objects so that it returns a
343 unicode instance if the argument is not an instance of basestring and
344 calling __str__ on the argument returns a unicode instance.
345
Tim Petersf4e69282006-02-27 17:15:31 +0000346- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
347 current thread state when the auto-GIL-state machinery knows about
348 it (since the thread state is being deleted, continuing to remember it
349 can't help, but can hurt if another thread happens to get created with
350 the same thread id).

Georg Brandl828fdef2006-04-01 08:59:03 +0000553 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Anthony Baxterc51ee692006-04-01 00:57:31 +0000554 later to build this - if you have an earlier version, the C extension
555 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +0000557- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
558 aren't officially supported here, and trying to use them will probably
559 raise an exception some day. But dicts have been allowed, and "mostly
560 worked", so support for them won't go away without warning.
561
Georg Brandl338ef7d2006-03-31 18:42:16 +0000562- Bug #1445068: getpass.getpass() can now be given an explicit stream

Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000581- email 4.0 package now integrated. This is largely the same as the email 3.0
582 package that was included in Python 2.3, except that PEP 8 module names are
583 now used (e.g. mail.message instead of email.Message). The MIME classes
584 have been moved to a subpackage (e.g. email.mime.text instead of
585 email.MIMEText). The old names are still supported for now. Several
586 deprecated Message methods have been removed and lots of bugs have been
587 fixed. More details can be found in the email package documentation.
588

590 (a subclass of tuple) that provides incremental decoders and encoders
591 (a way to use stateful codecs without the stream API). Python functions
592 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
593 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
594 have been added.

597 a ValueError instead of a StopIteration now (like file and cString.String do).

677
678 "The consensus of researchers in this area (at least as
679 expressed at the NIST Hash Function Workshop 10/31/05),
680 is that SHA-256 is a good choice for the time being, but
681 that research should continue, and other alternatives may
682 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000683

Tim Peterse3547fd2005-12-16 23:13:57 +0000847- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000848 flags on the HTTP listening socket.
849
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000850- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
851 Fixed by reading the HTTP body in chunks instead of one big socket.read().
852
Tim Peterse3547fd2005-12-16 23:13:57 +0000853- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000854 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
855
Martin v. Löwis1d11de62005-01-29 13:29:23 +0000856- Bug #1110478: Revert os.environ.update to do putenv again.
857
Thomas Hellerd6c6e222005-01-20 19:20:16 +0000858- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
859
Martin v. Löwis22b457e2005-01-16 08:40:58 +0000860- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
861
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000862- Enhancements to the csv module:
863
864 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +0000865 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +0000866 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000867 + Dialect parameter parsing has been re-implemented to improve error
868 reporting.
869 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
870 dictates.
871 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000872 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000873 types, rather than any object than can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000874 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
875 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000876 + reader now allows \r characters to be quoted (previously it only allowed
877 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +0000878 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000879 + Dialect classes passed to the module are no longer instantiated by
880 the module before being parsed (the former validation scheme required
881 this, but the mechanism was unreliable).
882 + The dialect registry now contains instances of the internal
883 C-coded dialect type, rather than references to python objects.
884 + the internal c-coded dialect type is now immutable.
885 + register_dialect now accepts the same keyword dialect specifications
886 as the reader and writer, allowing the user to register dialects
887 without first creating a dialect class.
888 + a configurable limit to the size of parsed fields has been added -
889 previously, an unmatched quote character could result in the entire
890 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +0000891 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000892 the parser field size limit (returning the former limit). The initial
893 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +0000894 + A line_num attribute has been added to the reader object, which tracks
895 the number of lines read from the source iterator. This is not
896 the same as the number of records returned, as records can span
897 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000898 + reader and writer objects were not being registered with the cyclic-GC.
899 This has been fixed.
900
Brett Cannone6539c42005-01-08 02:43:53 +0000901- _DummyThread objects in the threading module now delete self.__block that is
902 inherited from _Thread since it uses up a lock allocated by 'thread'. The
903 lock primitives tend to be limited in number and thus should not be wasted on
904 a _DummyThread object. Fixes bug #1089632.
905
Raymond Hettinger97db05d2005-01-07 08:15:41 +0000906- The imghdr module now detects Exif files.
907
Raymond Hettinger6065d322004-12-20 23:51:53 +0000908- StringIO.truncate() now correctly adjusts the size attribute.
909 (Bug #951915).
910
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000911- locale.py now uses an updated locale alias table (built using
912 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
913 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000914 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000915
Raymond Hettinger3557f422004-12-07 12:02:02 +0000916- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
917
Raymond Hettingera6b45cc2004-12-07 07:05:57 +0000918- the pickle module no longer accepts the deprecated None option in the
919 args tuple returned by __reduce__().
920
Brett Cannon84667c02004-12-07 03:25:18 +0000921- optparse now optionally imports gettext. This allows its use in setup.py.
922
Raymond Hettinger3489cad2004-12-05 05:20:42 +0000923- the pickle module no longer uses the deprecated bin parameter.
924
Raymond Hettinger1bc82f82004-12-05 03:58:17 +0000925- the shelve module no longer uses the deprecated binary parameter.
926
Raymond Hettinger6c92d762004-12-05 03:28:00 +0000927- the pstats module no longer uses the deprecated ignore() method.
928
Raymond Hettingerf3fa9462004-12-05 01:58:09 +0000929- the filecmp module no longer uses the deprecated use_statcache argument.
930
Raymond Hettinger664347b2004-12-04 21:21:53 +0000931- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
932 extended or overridden by subclasses. Formerly, the subclassed method would
933 be ignored by the rest of the module. (Bug #1078905).
934
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000935- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000936 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000937
Walter Dörwald36733692004-12-22 12:50:50 +0000938- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
939 once when a size argument is given. This prevents a buffer overflow in the
940 tokenizer with very long source lines.
941
Barry Warsaw538561e2006-01-01 21:48:54 +0000942- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
943 immediately after creating the object, without any intervening
944 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +0000945
Skip Montanaro05885812005-01-16 20:48:27 +0000946- The reconvert.quote function can now emit triple-quoted strings. The
947 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000948
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +0000949- ``UserString.MutableString`` now supports negative indices in
950 ``__setitem__`` and ``__delitem__``
951
Greg Ward40407942005-03-05 02:53:17 +0000952- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
953 correctly.
954
Walter Dörwaldbc8e6422005-04-21 21:32:03 +0000955- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
956 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
957 character even if the user has passed a size parameter to get a proper
958 line ending. Remove the special handling of a "\r\n" that has been split
959 between two lines.
960
Walter Dörwalda47d1c02005-08-30 10:23:14 +0000961- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
962 about illegal code points. The codec now supports PEP 293 style error
963 handlers.
964
Walter Dörwald78a78b02005-09-01 12:04:29 +0000965- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +0000966 from the input stream, so that the output is a byte string in the correct
967 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +0000968
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +0000969- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
970 considering it exactly like a '*'.
971
Walter Dörwald007f8df2005-10-09 19:42:27 +0000972- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
973 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +0000974
Walter Dörwald09f0dd52005-11-21 19:10:07 +0000975- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
976
Gustavo Niemeyer548148812006-01-31 18:34:13 +0000977- Patch #1413711: Certain patterns of differences were making difflib
978 touch the recursion limit.
979
Walter Dörwald58917a62006-03-31 15:26:22 +0000980- Bug #947906: An object oriented interface has been added to the calendar
981 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +0000982 called as a script (e.g. via ``python -mcalendar``). Localized month and
983 weekday names can be ouput (even if an exotic encoding is used) using
984 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +0000985
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000986Build
987-----
988
Neal Norwitz602d3392006-03-31 08:21:40 +0000989- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
990 by using -mieee gcc option.
991

993
Martin v. Löwis856bf9a2006-02-14 20:42:55 +0000994- Build support for Win64-AMD64 was added.
995
Martin v. Löwisa55e55e2006-02-11 15:55:14 +0000996- Patch #1428494: Prefer linking against ncursesw over ncurses library.
997
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +0000998- Patch #881820: look for openpty and forkpty also in libbsd.
999
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001000- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1001 The zlib module is now builtin on Windows.
1002
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001003- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1004
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001005- Bug #1189330: configure did not correctly determine the necessary
1006 value of LINKCC if python was built with GCC 4.0.
1007
Trent Mick8321b422005-07-26 02:29:21 +00001008- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1009 vulnerability in zlib 1.2.1 and 1.2.2.
1010
Brett Cannon08cd5982005-04-24 22:26:38 +00001011- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1012 flags that change binary compatibility. Changes were also made to
1013 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001014 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001015
Bob Ippolitoed233462005-03-29 13:47:59 +00001016- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1017 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1018 no longer exists). This configure patch makes things right.
1019
Martin v. Löwise2713be2005-03-08 15:03:08 +00001020- Bug #1158607: Build with --disable-unicode again.
1021
Brett Cannon46d96232005-02-16 00:07:19 +00001022- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1023 defined. Discovered as a result of not being able to build on OS X.
1024
Brett Cannon516592f2004-12-07 00:42:59 +00001025- setup.py now uses the directories specified in LDFLAGS using the -L option
1026 and in CPPFLAGS using the -I option for adding library and include
1027 directories, respectively, for compiling extension modules against. This has
1028 led to the core being compiled using the values in CPPFLAGS. It also removes
1029 the need for the special-casing of both DarwinPorts and Fink for darwin since
1030 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1031 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1032 Fink, ``-I/opt/local/include`` for DarwinPorts).
1033
Brett Cannon43802422005-02-10 20:48:03 +00001034- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1035 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1036 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1037 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001039C API
1040-----
1041
Tim Petersc9d78aa2006-03-26 23:27:58 +00001042- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1043 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1044 is obtained via the ``PyObject_`` family, it must be released via the
1045 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1046 always been officially true, but when Python's small-object allocator was
1047 introduced, an attempt was made to cater to a few extension modules
1048 discovered at the time that obtained memory via ``PyObject_New`` but
1049 released it via ``PyMem_DEL``. It's years later, and if such code still
1050 exists it will fail now (probably with segfaults, but calling wrong
1051 low-level memory management functions can yield many symptoms).
1052
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001053- Added a C API for set and frozenset objects.
1054
Raymond Hettinger66517482004-12-03 11:45:13 +00001055- Removed PyRange_New().
1056
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001057- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1058 mapping argument now. This string is used as a mapping table. Byte values
1059 greater than the length of the string and 0xFFFE are treated as undefined
1060 mappings.
