Anthony Baxter51bcb682006-04-05 14:51:42 +00007What's New in Python 2.5 alpha 2?
8=================================
9
Anthony Baxterc7d00322006-04-27 02:11:24 +000010*Release date: 27-APR-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Martin v. Löwis879768d2006-05-11 13:28:43 +000015- WindowsError now has two error code attributes: errno, which carries
16 the error values from errno.h, and winerror, which carries the error
17 values from winerror.h. Previous versions put the winerror.h values
18 (from GetLastError()) into the errno attribute.
19
Martin v. Löwis77736712006-05-04 05:51:03 +000020- Patch #1475845: Raise IndentationError for unexpected indent.
21
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000022- Patch #1479181: split open() and file() from being aliases for each other.
23
Thomas Heller1b046642006-04-18 18:51:06 +000024- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
25 by converting these apis from macros into exported functions again:
26
27 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
28 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
29 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
30 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
31 PyRun_String Py_CompileString
32
Martin v. Löwis45294a92006-04-18 06:24:08 +000033- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
34
Martin v. Löwis19ab6c92006-04-16 18:55:50 +000035- All uses of PyStructSequence_InitType have been changed to initialize
36 the type objects only once, even if the interpreter is initialized
37 multiple times.
38
Neal Norwitz61546162006-04-14 05:20:28 +000039- Bug #1454485, array.array('u') could crash the interpreter. This was
40 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
41 to unicode when it didn't make sense. 'u#' now requires a unicode string.
42
43- Py_UNICODE is unsigned. It was always documented as unsigned, but
44 due to a bug had a signed value in previous versions.
45
Tim Peters3a5e8b12006-04-11 01:44:07 +000046- Patch #837242: ``id()`` of any Python object always gives a positive
47 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
48 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000049 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000050 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000051
Tim Peters3a5e8b12006-04-11 01:44:07 +000052 def __hash__(self):
53 return id(self) # WRONG
54
55 because a hash result must be a (short) Python int but it was always
56 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000057 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000058 was always usable as a hash value before this patch. That's no longer
59 necessarily so.
60
61- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000062 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000063 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000064 #1454844)
65
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000066- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
67 involving generators that have paused outside of any ``try`` or ``with``
68 blocks. (In 2.5a1, a paused generator that was part of a reference
69 cycle could not be garbage collected, regardless of whether it was
70 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +000071
Anthony Baxter51bcb682006-04-05 14:51:42 +000072Extension Modules
73-----------------
74
Tim Petersad2ef332006-05-10 02:43:01 +000075- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
Martin v. Löwisd4e3bb32006-05-06 16:32:54 +000076 As a result, these functions now raise WindowsError instead of OSError.
Martin v. Löwis8e0d4942006-05-04 10:08:42 +000077
Martin v. Löwis86725192006-05-01 06:28:01 +000078- Calling Tk_Init twice is refused if the first call failed as that
79 may deadlock.
80
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000081- Patch #1191065: Fix preprocessor problems on systems where recvfrom
82 is a macro.
83
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000084- Bug #1467952: os.listdir() now correctly raises an error if readdir()
85 fails with an error condition.
86
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000087- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
88
89- Bug #1117761: bsddb.*open() no longer raises an exception when using
90 the cachesize parameter.
91
92- Bug #1149413: bsddb.*open() no longer raises an exception when using
93 a temporary db (file=None) with the 'n' flag to truncate on open.
94
95- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
96 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +000097
Armin Rigoa9017c32006-04-19 11:50:27 +000098- Patch #1062014: AF_UNIX sockets under Linux have a special
99 abstract namespace that is now fully supported.
100
Anthony Baxter51bcb682006-04-05 14:51:42 +0000101Library
102-------
103
Georg Brandl19564802006-05-10 17:13:20 +0000104- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
105 stdout arguments, making it possible to redirect input and output
106 for remote debugging.
107
Georg Brandl38c6a222006-05-10 16:26:03 +0000108- Patch #1484695: Update the tarfile module to version 0.8. This fixes
109 a couple of issues, notably handling of long file names using the
110 GNU LONGNAME extension.
111
Tim Petersad2ef332006-05-10 02:43:01 +0000112- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
113 new flag when ``name`` is already the name of an option flag.
114
Georg Brandl1bb62302006-05-03 18:18:32 +0000115- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
116 package.
117
Georg Brandl3583cff2006-04-30 18:14:54 +0000118- Patch #1472854: make the rlcompleter.Completer class usable on non-
119 UNIX platforms.
120
Georg Brandlfa42bd72006-04-30 07:06:11 +0000121- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
122
Tim Peters711bf302006-04-25 03:31:36 +0000123- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
124 a doctest to be skipped (the code is not run, and the expected output
125 or exception is ignored).
126
Nick Coghlanda2268f2006-04-24 04:37:15 +0000127- Fixed contextlib.nested to cope with exceptions being raised and
128 caught inside exit handlers.
129
Greg Wardab05edc2006-04-23 03:47:58 +0000130- Updated optparse module to Optik 1.5.1 (allow numeric constants in
131 hex, octal, or binary; add ``append_const`` action; keep going if
132 gettext cannot be imported; added ``OptionParser.destroy()`` method;
133 added ``epilog`` for better help generation).
134
Tim Peters21fbd572006-04-21 21:18:10 +0000135- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
136 called from a thread spawned as a side effect of importing a module.
137
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000138- The pydoc module now supports documenting packages contained in
139 .zip or .egg files.
140
141- The pkgutil module now has several new utility functions, such
142 as ``walk_packages()`` to support working with packages that are either
143 in the filesystem or zip files.
144
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000145- The mailbox module can now modify and delete messages from
146 mailboxes, in addition to simply reading them. Thanks to Gregory
147 K. Johnson for writing the code, and to the 2005 Google Summer of
148 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000149
Tim Petersc7605f22006-04-17 21:12:33 +0000150- The ``__del__`` method of class ``local`` in module ``_threading_local``
151 returned before accomplishing any of its intended cleanup.
152
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000153- Patch #790710: Add breakpoint command lists in pdb.
154
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000155- Patch #1063914: Add Tkinter.Misc.clipboard_get().
156
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000157- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
158
Anthony Baxtere29002c2006-04-12 12:07:31 +0000159- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
160 Windows. Bug #1469163.
161
Phillip J. Eby47032112006-04-11 01:07:43 +0000162- The warnings, linecache, inspect, traceback, site, and doctest modules
163 were updated to work correctly with modules imported from zipfiles or
164 via other PEP 302 __loader__ objects.
165
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000166- Patch #1467770: Reduce usage of subprocess._active to processes which
167 the application hasn't waited on.
168
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000169- Patch #1462222: Fix Tix.Grid.
170
Neal Norwitza31bf182006-04-09 03:35:43 +0000171- Fix exception when doing glob.glob('anything*/')
172
Skip Montanaro262fb922006-04-21 02:31:07 +0000173- The pstats.Stats class accepts an optional stream keyword argument to
174 direct output to an alternate file-like object.
175
Anthony Baxter51bcb682006-04-05 14:51:42 +0000176Build
177-----
178
Martin v. Löwisb75d43d2006-04-29 12:37:25 +0000179- Patch #1471883: Add --enable-universalsdk.
180
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000181- The Makefile now has a reindent target, which runs reindent.py on
182 the library.
183
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000184- Patch #1470875: Building Python with MS Free Compiler
185
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000186- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000187
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000188- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
189 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000190 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000191 CXX from --with-cxx-main, see description in README.
192
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000193- Patch #1429775: Link extension modules with the shared libpython.
194
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000195- Fixed a libffi build problem on MIPS systems.

200Tests
201-----
202
Nick Coghlanda2268f2006-04-24 04:37:15 +0000203- test_contextlib now checks contextlib.nested can cope with exceptions
204 being raised and caught inside exit handlers.
205
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000206- test_cmd_line now checks operation of the -m and -c command switches
207
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000208- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
209 it separately and by hand. It also wasn't cleaning up its changes to
210 the current Decimal context.
211
Thomas Woutersabd08882006-04-26 15:53:30 +0000212- regrtest.py now has a -M option to run tests that test the new limits of
213 containers, on 64-bit architectures. Running these tests is only sensible
214 on 64-bit machines with more than two gigabytes of memory. The argument
215 passed is the maximum amount of memory for the tests to use.

219
220- Added the Python benchmark suite pybench to the Tools/ directory;
221 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000223Documentation
224-------------
225
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000226- PEP 343: Added Context Types section to the library reference
227 and attempted to bring other PEP 343 related documentation into
228 line with the implementation and/or python-dev discussions.
229
Tim Peters8dc73d22006-04-24 02:03:16 +0000230- Bug #1337990: clarified that ``doctest`` does not support examples
231 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000234What's New in Python 2.5 alpha 1?
235=================================
236
Anthony Baxterebed3f62006-04-03 15:03:44 +0000237*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000238
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000239Core and builtins
240-----------------
241
Nick Coghlan43832302006-04-23 17:04:07 +0000242- PEP 338: -m command line switch now delegates to runpy.run_module
243 allowing it to support modules in packages and zipfiles
244
Martin v. Löwisc661b882006-04-20 04:54:23 +0000245- On Windows, .DLL is not an accepted file name extension for
246 extension modules anymore; extensions are only found if they
247 end in .PYD.
248
Martin v. Löwisea62d252006-04-03 10:56:49 +0000249- Bug #1421664: sys.stderr.encoding is now set to the same value as
250 sys.stdout.encoding.
251
Neal Norwitz92e212f2006-04-03 04:48:37 +0000252- __import__ accepts keyword arguments.
253
Georg Brandlccadf842006-03-31 18:54:53 +0000254- Patch #1460496: round() now accepts keyword arguments.
255
Anthony Baxter262c00a2006-03-30 10:53:17 +0000256- Fixed bug #1459029 - unicode reprs were double-escaped.
257
Hye-Shik Changd478f342006-03-23 12:32:36 +0000258- Patch #1396919: The system scope threads are reenabled on FreeBSD
259 5.4 and later versions.
260
Neal Norwitze98ccf62006-03-23 05:39:47 +0000261- Bug #1115379: Compiling a Unicode string with an encoding declaration
262 now gives a SyntaxError.
263
Georg Brandlabd1ff82006-03-18 07:59:59 +0000264- Previously, Python code had no easy way to access the contents of a
265 cell object. Now, a ``cell_contents`` attribute has been added
266 (closes patch #1170323).
267
Tim Peterscf79aac2006-03-16 01:14:46 +0000268- Patch #1123430: Python's small-object allocator now returns an arena to
269 the system ``free()`` when all memory within an arena becomes unused
270 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
271 freed. Some applications will see a drop in virtual memory size now,
272 especially long-running applications that, from time to time, temporarily
273 use a large number of small objects. Note that when Python returns an
274 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000275 platform C library will in turn return that memory to the operating system.
276 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000277 appears to be effective at least on Microsoft C and gcc-based systems.
278 Thanks to Evan Jones for hard work and patience.
279
Georg Brandl533ff6f2006-03-08 18:09:27 +0000280- Patch #1434038: property() now uses the getter's docstring if there is
281 no "doc" argument given. This makes it possible to legitimately use
282 property() as a decorator to produce a read-only property.
283
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000284- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
285 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
286 of requiring an int or long in slicing and a few other contexts, enabling
287 other objects (e.g. Numeric Python's integers) to be used as slice indices.
288
Neal Norwitz995acdf2006-03-07 05:01:00 +0000289- Fixed various bugs reported by Coverity's Prevent tool.
290
Brett Cannonbf364092006-03-01 04:25:17 +0000291- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
292 new exception base class, BaseException, which has a new message attribute.
293 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
294 Raising a string exception now raises a DeprecationWarning.
295
Thomas Woutersfb609f42006-02-28 16:37:25 +0000296- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
297 explicitly relative, using 'from .module import name' to mean 'from the same
298 package as this module is in. Imports without dots still default to the
299 old relative-then-absolute, unless 'from __future__ import
300 absolute_import' is used.
301
Brett Cannona7446e32006-02-27 23:39:10 +0000302- Properly check if 'warnings' raises an exception (usually when a filter set
303 to "error" is triggered) when raising a warning for raising string
304 exceptions.
305
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000306- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000307 The name was removed from Include/code.h.
308
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000309- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000310
Guido van Rossum1968ad32006-02-25 22:38:04 +0000311- Patch 1433928:
312 - The copy module now "copies" function objects (as atomic objects).
313 - dict.__getitem__ now looks for a __missing__ hook before raising
314 KeyError.
315
Tim Peters84ef21c2006-02-28 20:39:06 +0000316- PEP 343: with statement implemented. Needs ``from __future__ import
317 with_statement``. Use of 'with' as a variable will generate a warning.
318 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000319 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000320 The following objects have __context__ methods:
321 - The built-in file type.
322 - The thread.LockType type.
323 - The following types defined by the threading module:
324 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
325 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000326
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000327- Fix the encodings package codec search function to only search
328 inside its own package. Fixes problem reported in patch #1433198.
329
330 Note: Codec packages should implement and register their own
331 codec search function. PEP 100 has the details.
332
Martin v. Löwis18e16552006-02-15 17:27:45 +0000333- PEP 353: Using ssize_t as the index type.
334
Neal Norwitzfc76d632006-01-10 06:03:13 +0000335- Patch #1400181, fix unicode string formatting to not use the locale.
336 This is how string objects work. u'%f' could use , instead of .
337 for the decimal point. Now both strings and unicode always use periods.
338
Neal Norwitz671b9e32006-01-09 07:07:12 +0000339- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
340 configure would break checking curses.h.
341
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000342- Bug #959576: The pwd module is now builtin. This allows Python to be
343 built on UNIX platforms without $HOME set.
344
Neal Norwitzc10978f2005-12-19 06:07:16 +0000345- Bug #1072182, fix some potential problems if characters are signed.
346
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000347- Bug #889500, fix line number on SyntaxWarning for global declarations.
348
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000349- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
350
Neal Norwitze7214a12005-12-18 05:03:17 +0000351- Support for converting hex strings to floats no longer works.
352 This was not portable. float('0x3') now raises a ValueError.
353
Barry Warsaw2a38a862005-12-18 01:27:35 +0000354- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000355 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000356 is now displayed in interactive prompt banner.
357
Georg Brandlfa166682005-12-17 21:45:17 +0000358- Implementation of PEP 341 - Unification of try/except and try/finally.
359 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000360 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000361
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000362- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
363 now encodes backslash correctly.
364
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000365- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
366
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000367- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000368 and long longs.
369
Neal Norwitz67715f02005-11-09 06:59:35 +0000370- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000371 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000372 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000373
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000374- Replaced most Unicode charmap codecs with new ones using the
375 new Unicode translate string feature in the builtin charmap
376 codec; the codecs were created from the mapping tables available
377 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
378 encodings now include a mapping for the Apple logo)
379
Tim Peterse3547fd2005-12-16 23:13:57 +0000380- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000381
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000382- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000383
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000384- A new AST parser implementation was completed. The abstract
385 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000386 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000387
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000388- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000389 The following code now raises a SyntaxError: foo(a = i for i in range(10))
390
Neal Norwitz708e51a2005-10-03 04:48:15 +0000391- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
392
Neal Norwitz11bd1192005-10-03 00:54:56 +0000393- SF Bug #887946: fix segfault when redirecting stdin from a directory.
394 Provide a warning when a directory is passed on the command line.
395
Neal Norwitz40d37812005-10-02 01:48:49 +0000396- Fix segfault with invalid coding.
397
398- SF bug #772896: unknown encoding results in MemoryError.
399
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000400- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000401 supported a __len__() method which evaluated to False when the iterator
402 was empty.
403
Guido van Rossum630db602005-09-20 18:49:54 +0000404- On 64-bit platforms, when __len__() returns a value that cannot be
405 represented as a C int, raise OverflowError.
406
Skip Montanarof8948ca2005-09-19 03:54:46 +0000407- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000408 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000409
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000410- SF bug #893549: parsing keyword arguments was broken with a few format
411 codes.
412
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000413- Changes donated by Elemental Security to make it work on AIX 5.3
414 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
415 bug #105470: test_pwd fails on 64bit system (Opteron).
416
Guido van Rossum539c6622005-09-14 17:49:54 +0000417- Changes donated by Elemental Security to make it work on HP-UX 11 on
418 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
419
Georg Brandl4550b8d2005-08-26 06:43:52 +0000420- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000421 (fixes bug #1119418).
422
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000423- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
424
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000425- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
426 exceptions that cause a function to exit.
427
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000428- The implementation of set() and frozenset() was revised to use its
429 own internal data structure. Memory consumption is reduced by 1/3
430 and there are modest speed-ups as well. The API is unchanged.
431
Tim Petersde7990b2005-07-17 23:45:23 +0000432- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
433
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000434- SF bug #1229429: PyObject_CallMethod failed to decrement some
435 reference counts in some error exit cases.
436
Tim Petersecc6e6a2005-07-10 22:30:55 +0000437- SF bug #1185883: Python's small-object memory allocator took over
438 a block managed by the platform C library whenever a realloc specified
439 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000440 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000441 portable way to copy data from the C-managed block into Python's
442 small-object space without risking a memory fault. Python's small-object
443 realloc now leaves such blocks under the control of the platform C
444 realloc.
445
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000446- SF bug #1232517: An overflow error was not detected properly when
447 attempting to convert a large float to an int in os.utime().
448
Raymond Hettinger3296e692005-06-29 23:29:56 +0000449- SF bug #1224347: hex longs now print with lowercase letters just
450 like their int counterparts.
451
Michael W. Hudson188d4362005-06-20 16:52:57 +0000452- SF bug #1163563: the original fix for bug #1010677 ("thread Module
453 Breaks PyGILState_Ensure()") broke badly in the case of multiple
454 interpreter states; back out that fix and do a better job (see
455 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
456 for a longer write-up of the problem).
457
Michael W. Hudsondf888462005-06-03 14:41:55 +0000458- SF patch #1180995: marshal now uses a binary format by default when
459 serializing floats.
460
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000461- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
462 the routines that promise to produce IEEE 754 binary representations
463 of floats now simply copy bytes around.
464
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000465- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
466 278.
467
Brett Cannonc3647ac2005-04-26 03:45:26 +0000468- patch #1109424: int, long, float, complex, and unicode now check for the
469 proper magic slot for type conversions when subclassed. Previously the
470 magic slot was ignored during conversion. Semantics now match the way
471 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000472 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000473 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000474 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000475
Barry Warsawc8d907c2005-04-19 23:43:40 +0000476- Descriptors defined in C with a PyGetSetDef structure, where the setter is
477 NULL, now raise an AttributeError when attempting to set or delete the
478 attribute. Previously a TypeError was raised, but this was inconsistent
479 with the equivalent pure-Python implementation.
480
Michael W. Hudson774479c2005-04-18 08:46:17 +0000481- It is now safe to call PyGILState_Release() before
482 PyEval_InitThreads() (note that if there is reason to believe there
483 are multiple threads around you still must call PyEval_InitThreads()
484 before using the Python API; this fix is for extension modules that
485 have no way of knowing if Python is multi-threaded yet).
486
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000487- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
488 disabled caused a crash.
489
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000490- Bug #1165306: instancemethod_new allowed the creation of a method
491 with im_class == im_self == NULL, which caused a crash when called.
492
Tim Petersecc6e6a2005-07-10 22:30:55 +0000493- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000494 fixes the crash seen in bug #1165761
495
Raymond Hettinger96229b12005-03-11 06:49:40 +0000496- Added two new builtins, any() and all().
497
Brett Cannon409d8f22005-03-05 06:47:57 +0000498- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000499 (e.g., ``class C(): pass`` is no longer a syntax error).
500 Patch #1176012 added support to the 'parser' module and 'compiler' package
501 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000502
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000503- Patch #1115086: Support PY_LONGLONG in structmember.
504
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000505- Bug #1155938: new style classes did not check that __init__() was
506 returning None.
507
Tim Petersecc6e6a2005-07-10 22:30:55 +0000508- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000509 ('\') with a specific error message.
510
Martin v. Löwisff232d72005-03-03 09:24:38 +0000511- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
512
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000513- Bug #1124295: the __name__ attribute of file objects was
514 inadvertently made inaccessible in restricted mode.
515
Tim Petersecc6e6a2005-07-10 22:30:55 +0000516- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000517 an ferror() call.
518
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000519- min() and max() now support key= arguments with the same meaning as in
520 list.sort().
521
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000522- The peephole optimizer now performs simple constant folding in expressions:
523 (2+3) --> (5).
524
Raymond Hettingera422c342005-01-11 03:03:27 +0000525- set and frozenset objects can now be marshalled. SF #1098985.
526
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000527- Bug #1077106: Poor argument checking could cause memory corruption
528 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000529
Jeremy Hyltonab630502005-02-04 18:44:06 +0000530- The parser did not complain about future statements in illegal
531 positions. It once again reports a syntax error if a future
532 statement occurs after anything other than a doc string.
533
Neil Schemenauercf52c072005-08-12 17:34:58 +0000534- Change the %s format specifier for str objects so that it returns a
535 unicode instance if the argument is not an instance of basestring and
536 calling __str__ on the argument returns a unicode instance.
537
Tim Petersf4e69282006-02-27 17:15:31 +0000538- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
539 current thread state when the auto-GIL-state machinery knows about
540 it (since the thread state is being deleted, continuing to remember it
541 can't help, but can hurt if another thread happens to get created with
542 the same thread id).
543
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000544Extension Modules
545-----------------
546
Georg Brandl43f08a82006-03-31 18:01:16 +0000547- Patch #1380952: fix SSL objects timing out on consecutive read()s
548
Neal Norwitz05a45592006-03-20 06:30:08 +0000549- Patch #1309579: wait3 and wait4 were added to the posix module.
550
Anthony Baxterfa869072006-03-20 05:21:58 +0000551- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
552 In addition, the existing ulaw code was updated.
553
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000554- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000555 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000556
Neal Norwitz10be10c2006-03-16 06:50:13 +0000557- Everything under lib-old was removed. This includes the following modules:
558 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000559 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000560 util, whatsound, whrandom, zmod
561
562- The following modules were removed: regsub, reconvert, regex, regex_syntax.
563
564- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000565 is deprecated. The undocumented re.engine variable no longer exists.
566
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000567- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
568 SS2 (single-shift 2) escape sequences correctly.
569
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000570- The unicodedata module was updated to the 4.1 version of the Unicode
571 database. The 3.2 version is still available as unicodedata.db_3_2_0
572 for applications that require this specific version (such as IDNA).
573
Neal Norwitzb62c4332006-03-04 18:35:47 +0000574- The timing module is no longer built by default. It was deprecated
575 in PEP 4 in Python 2.0 or earlier.

732-------
733
Nick Coghlan43832302006-04-23 17:04:07 +0000734- PEP 338: new module runpy defines a run_module function to support

Georg Brandl828fdef2006-04-01 08:59:03 +0000749 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000750 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000751 module will not be built.
752
Tim Petersc17976e2006-04-01 00:26:53 +0000753- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
754 aren't officially supported here, and trying to use them will probably
755 raise an exception some day. But dicts have been allowed, and "mostly
756 worked", so support for them won't go away without warning.
757
Georg Brandl338ef7d2006-03-31 18:42:16 +0000758- Bug #1445068: getpass.getpass() can now be given an explicit stream

776
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000777- email 4.0 package now integrated. This is largely the same as the email 3.0
778 package that was included in Python 2.3, except that PEP 8 module names are
779 now used (e.g. mail.message instead of email.Message). The MIME classes
780 have been moved to a subpackage (e.g. email.mime.text instead of
781 email.MIMEText). The old names are still supported for now. Several
782 deprecated Message methods have been removed and lots of bugs have been
783 fixed. More details can be found in the email package documentation.
784
Walter Dörwald40108c92006-03-27 08:15:44 +0000785- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
786 (a subclass of tuple) that provides incremental decoders and encoders
787 (a way to use stateful codecs without the stream API). Python functions
788 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
789 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
790 have been added.

793 a ValueError instead of a StopIteration now (like file and cString.String do).
794 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
795 called before (like file and StringIO.StringIO do).

865 LoadError as documented, instead of IOError. For compatibility,
866 LoadError subclasses IOError.
867
Brett Cannon3cbd0382005-12-16 22:49:23 +0000868- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +0000869 SHA1, 224, 256, 384, and 512. Note that recent developments make the
870 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
871 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
872 Ronald L. Rivest offered this advice for Python:
873
874 "The consensus of researchers in this area (at least as
875 expressed at the NIST Hash Function Workshop 10/31/05),
876 is that SHA-256 is a good choice for the time being, but
877 that research should continue, and other alternatives may
878 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000879
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000880- Added a subset of Fredrik Lundh's ElementTree package. Available

933 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000934 correct line numbers for decoding errors in source code.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +0000972- The tokenize module now detects and reports indentation errors.
973 Bug #1224621.
974
Raymond Hettinger68c04532005-06-10 11:05:19 +0000975- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000976 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000977 the generate_tokens() function now accepts a callable argument that

995
Raymond Hettinger267b8682005-03-27 10:47:39 +0000996- decimal operator and comparison methods now return NotImplemented
997 instead of raising a TypeError when interacting with other types. This
998 allows other classes to implement __radd__ style methods and have them
999 work as expected.
1000
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001001- Bug #1163325: Decimal infinities failed to hash. Attempting to
1002 hash a NaN raised an InvalidOperation instead of a TypeError.
1003
Tim Petersecc6e6a2005-07-10 22:30:55 +00001004- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1038
Guido van Rossumd0641422005-02-03 15:01:24 +00001039- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1040 disables recursive traversal through instance attributes, which can
1041 be exploited in various ways.
1042
Tim Peterse3547fd2005-12-16 23:13:57 +00001043- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001044 flags on the HTTP listening socket.
1045
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001046- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1047 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1048
Tim Peterse3547fd2005-12-16 23:13:57 +00001049- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001050 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1051

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001054- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1055
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001056- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1057
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001058- Enhancements to the csv module:
1059
1060 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001061 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001062 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001063 + Dialect parameter parsing has been re-implemented to improve error
1064 reporting.
1065 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1066 dictates.
1067 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001068 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001069 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001070 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1071 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001072 + reader now allows \r characters to be quoted (previously it only allowed
1073 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001074 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001075 + Dialect classes passed to the module are no longer instantiated by
1076 the module before being parsed (the former validation scheme required
1077 this, but the mechanism was unreliable).
1078 + The dialect registry now contains instances of the internal
1079 C-coded dialect type, rather than references to python objects.
1080 + the internal c-coded dialect type is now immutable.
1081 + register_dialect now accepts the same keyword dialect specifications
1082 as the reader and writer, allowing the user to register dialects
1083 without first creating a dialect class.
1084 + a configurable limit to the size of parsed fields has been added -
1085 previously, an unmatched quote character could result in the entire
1086 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001087 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001088 the parser field size limit (returning the former limit). The initial
1089 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001090 + A line_num attribute has been added to the reader object, which tracks
1091 the number of lines read from the source iterator. This is not
1092 the same as the number of records returned, as records can span
1093 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001094 + reader and writer objects were not being registered with the cyclic-GC.
1095 This has been fixed.
1096
Brett Cannone6539c42005-01-08 02:43:53 +00001097- _DummyThread objects in the threading module now delete self.__block that is
1098 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1099 lock primitives tend to be limited in number and thus should not be wasted on
1100 a _DummyThread object. Fixes bug #1089632.
1101
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001102- The imghdr module now detects Exif files.
1103
Raymond Hettinger6065d322004-12-20 23:51:53 +00001104- StringIO.truncate() now correctly adjusts the size attribute.
1105 (Bug #951915).
1106
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001107- locale.py now uses an updated locale alias table (built using
1108 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1109 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001110 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001111
Raymond Hettinger3557f422004-12-07 12:02:02 +00001112- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1113
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001114- the pickle module no longer accepts the deprecated None option in the
1115 args tuple returned by __reduce__().
1116
Brett Cannon84667c02004-12-07 03:25:18 +00001117- optparse now optionally imports gettext. This allows its use in setup.py.
1118
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001119- the pickle module no longer uses the deprecated bin parameter.
1120

1126
Raymond Hettinger664347b2004-12-04 21:21:53 +00001127- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1128 extended or overridden by subclasses. Formerly, the subclassed method would
1129 be ignored by the rest of the module. (Bug #1078905).
1130
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001131- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001132 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001133
Walter Dörwald36733692004-12-22 12:50:50 +00001134- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1135 once when a size argument is given. This prevents a buffer overflow in the
1136 tokenizer with very long source lines.
1137
Barry Warsaw538561e2006-01-01 21:48:54 +00001138- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1139 immediately after creating the object, without any intervening
1140 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001141
Skip Montanaro05885812005-01-16 20:48:27 +00001142- The reconvert.quote function can now emit triple-quoted strings. The
1143 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001144
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001145- ``UserString.MutableString`` now supports negative indices in
1146 ``__setitem__`` and ``__delitem__``
1147
Greg Ward40407942005-03-05 02:53:17 +00001148- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1149 correctly.
1150
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001151- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1152 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1153 character even if the user has passed a size parameter to get a proper
1154 line ending. Remove the special handling of a "\r\n" that has been split
1155 between two lines.
1156
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001157- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1158 about illegal code points. The codec now supports PEP 293 style error
1159 handlers.
1160
Walter Dörwald78a78b02005-09-01 12:04:29 +00001161- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001162 from the input stream, so that the output is a byte string in the correct
1163 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001164
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001165- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1166 considering it exactly like a '*'.
1167
Walter Dörwald007f8df2005-10-09 19:42:27 +00001168- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1169 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001170
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001171- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1172
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001173- Patch #1413711: Certain patterns of differences were making difflib
1174 touch the recursion limit.
1175
Walter Dörwald58917a62006-03-31 15:26:22 +00001176- Bug #947906: An object oriented interface has been added to the calendar
1177 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001178 called as a script (e.g. via ``python -mcalendar``). Localized month and
1179 weekday names can be ouput (even if an exotic encoding is used) using
1180 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001182Build
1183-----
1184
Neal Norwitz602d3392006-03-31 08:21:40 +00001185- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1186 by using -mieee gcc option.
1187

1189
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001190- Build support for Win64-AMD64 was added.
1191
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001192- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1193
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001194- Patch #881820: look for openpty and forkpty also in libbsd.
1195
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001196- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1197 The zlib module is now builtin on Windows.
1198
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001199- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1200
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001201- Bug #1189330: configure did not correctly determine the necessary
1202 value of LINKCC if python was built with GCC 4.0.
1203
Trent Mick8321b422005-07-26 02:29:21 +00001204- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1205 vulnerability in zlib 1.2.1 and 1.2.2.
1206
Brett Cannon08cd5982005-04-24 22:26:38 +00001207- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1208 flags that change binary compatibility. Changes were also made to
1209 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001210 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001211
Bob Ippolitoed233462005-03-29 13:47:59 +00001212- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1213 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1214 no longer exists). This configure patch makes things right.
1215
Martin v. Löwise2713be2005-03-08 15:03:08 +00001216- Bug #1158607: Build with --disable-unicode again.
1217
Brett Cannon46d96232005-02-16 00:07:19 +00001218- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1219 defined. Discovered as a result of not being able to build on OS X.
1220
Brett Cannon516592f2004-12-07 00:42:59 +00001221- setup.py now uses the directories specified in LDFLAGS using the -L option
1222 and in CPPFLAGS using the -I option for adding library and include
1223 directories, respectively, for compiling extension modules against. This has
1224 led to the core being compiled using the values in CPPFLAGS. It also removes
1225 the need for the special-casing of both DarwinPorts and Fink for darwin since
1226 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1227 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1228 Fink, ``-I/opt/local/include`` for DarwinPorts).
1229
Brett Cannon43802422005-02-10 20:48:03 +00001230- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1231 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1232 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1233 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001235C API
1236-----
1237
Tim Petersc9d78aa2006-03-26 23:27:58 +00001238- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1239 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1240 is obtained via the ``PyObject_`` family, it must be released via the
1241 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1242 always been officially true, but when Python's small-object allocator was
1243 introduced, an attempt was made to cater to a few extension modules
1244 discovered at the time that obtained memory via ``PyObject_New`` but
1245 released it via ``PyMem_DEL``. It's years later, and if such code still
1246 exists it will fail now (probably with segfaults, but calling wrong
1247 low-level memory management functions can yield many symptoms).
1248
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001249- Added a C API for set and frozenset objects.
1250

1252
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001253- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1254 mapping argument now. This string is used as a mapping table. Byte values
1255 greater than the length of the string and 0xFFFE are treated as undefined
1256 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001262- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001263
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001264- Patch #1276356: New resource "urlfetch" is implemented. This enables
1265 even impatient people to run tests that require remote files.
