12Core and builtins
13-----------------
14
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000015- Bug #1441486: The literal representation of -(sys.maxint - 1)
16 again evaluates to a int object, not a long.
17
Neil Schemenauer0e07b602006-07-09 16:16:34 +000018- Bug #1501934: The scope of global variables that are locally assigned
19 using augmented assignment is now correctly determined.
20
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000021- Bug #927248: Recursive method-wrapper objects can now safely
22 be released.
23
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000024- Bug #1417699: Reject locale-specific decimal point in float()
25 and atof().
26
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000027- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
28 omit a default "error" argument for NULL pointer. This allows
29 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000030
Neal Norwitzfb48afa2006-07-08 05:31:37 +000031- Bug #1519018: 'as' is now validated properly in import statements.

39
Thomas Heller5becdbe2006-07-06 08:48:35 +000040- Patch #1517790: It is now possible to use custom objects in the ctypes
41 foreign function argtypes sequence as long as they provide a from_param
42 method, no longer is it required that the object is a ctypes type.
43
Thomas Woutersadd19112006-07-05 11:03:49 +000044- string.Template() now correctly handles tuple-values. Previously,
45 multi-value tuples would raise an exception and single-value tuples would
46 be treated as the value they contain, instead.
47
Martin v. Löwisede77f52006-07-03 13:01:35 +000048- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

Martin v. Löwis2b88f632006-07-03 10:19:49 +000058 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000059
Martin v. Löwisbd39c032006-07-03 09:44:00 +000060- Bug #1514703: Only setup canvas window in turtle when the canvas
61 is created.
62
Martin v. Löwis7596e832006-07-01 15:33:37 +000063- Bug #1513223: .close() of a _socketobj now releases the underlying
64 socket again, which then gets closed as it becomes unreferenced.
65
Thomas Hellerbde08132006-06-29 18:34:15 +000066- The '_ctypes' extension module now works when Python is configured
67 with the --without-threads option.
68
Fred Drake10497c82006-06-29 02:57:48 +000069- Bug #1504333: Make sgmllib support angle brackets in quoted
70 attribute values.
71
72- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
73 sgmllib ('[' and ']' were not accepted).
74
Georg Brandl1be63af2006-06-28 20:23:25 +000075- Fix a bug in the turtle module's end_fill function.
76
Brett Cannon53ab5b72006-06-22 16:49:14 +000077- Bug #1510580: The 'warnings' module improperly required that a Warning
78 category be either a types.ClassType and a subclass of Warning. The proper
79 check is just that it is a subclass with Warning as the documentation states.
80
Georg Brandlad29e632006-06-21 17:45:17 +000081- The compiler module now correctly compiles the new try-except-finally
82 statement (bug #1509132).
83
Neal Norwitz60373cd2006-06-22 06:30:50 +000084- The wsgiref package is now installed properly on Unix.
85
Vinay Sajip28e57612006-07-01 10:45:20 +000086- A bug was fixed in logging.config.fileConfig() which caused a crash on
87 shutdown when fileConfig() was called multiple times.
88
Gerhard Häring762fbd32006-07-02 17:48:30 +000089- The sqlite3 module did cut off data from the SQLite database at the first
90 null character before sending it to a custom converter. This has been fixed
91 now.
92
Neal Norwitz0f8b31a2006-06-28 06:28:31 +000093Extension Modules
94-----------------
95
Martin v. Löwisee1e06d2006-07-02 18:44:00 +000096- Bug #1513646: os.access on Windows now correctly determines write
97 access, again.
98
Neal Norwitz0f8b31a2006-06-28 06:28:31 +000099- Bug #1512695: cPickle.loads could crash if it was interrupted with
100 a KeyboardInterrupt.
101
Neal Norwitza12aa882006-07-06 06:45:08 +0000102- Bug #1296433: parsing XML with a non-default encoding and
103 a CharacterDataHandler could crash the interpreter in pyexpat.
104
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000105Build
106-----
107
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000108- 'configure' now detects the zlib library the same way as distutils.
109 Previously, the slight difference could cause compilation errors of the
110 'zlib' module on systems with more than one version of zlib.
111
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000112- The MSI compileall step was fixed to also support a TARGETDIR
113 with spaces in it.
114
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000115- Bug #1517388: sqlite3.dll is now installed on Windows independent
116 of Tcl/Tk.
117
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000118- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000119 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000120
Neal Norwitzb15ac312006-06-29 04:10:08 +0000121Tests
122-----
123
124- Call os.waitpid() at the end of tests that spawn child processes in order
125 to minimize resources (zombies).
126
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000127Documentation
128-------------
129
Nick Coghlan2d792252006-07-06 13:47:18 +0000130- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
131 documentation for the warnings module.
132
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000133- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000138
Anthony Baxterd1136802006-06-19 12:04:15 +0000139*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000140
141Core and builtins
142-----------------
143
Georg Brandla56b9152006-06-19 06:35:54 +0000144- Patch #1507676: Error messages returned by invalid abstract object operations
145 (such as iterating over an integer) have been improved and now include the
146 type of the offending object to help with debugging.
147
Brett Cannonea3912b2006-06-13 21:46:41 +0000148- Bug #992017: A classic class that defined a __coerce__() method that returned
149 its arguments swapped would infinitely recurse and segfault the interpreter.
150
Neal Norwitz909eb122006-06-12 02:13:21 +0000151- Fix the socket tests so they can be run concurrently.
152
Neal Norwitzb9845e72006-06-12 02:11:18 +0000153- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000154 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000155
Brett Cannon22565aa2006-06-09 22:31:23 +0000156- Bug #532646: object.__call__() will continue looking for the __call__
157 attribute on objects until one without one is found. This leads to recursion
158 when you take a class and set its __call__ attribute to an instance of the
159 class. Originally fixed for classic classes, but this fix is for new-style.
160 Removes the infinite_rec_3 crasher.
161
Georg Brandl24250812006-06-09 18:45:48 +0000162- The string and unicode methods startswith() and endswith() now accept
163 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
164
Brett Cannonde3b0522006-06-08 17:00:45 +0000165- Buffer objects, at the C level, never used the char buffer
166 implementation even when the char buffer for the wrapped object was
167 explicitly requested (originally returned the read or write buffer).
168 Now a TypeError is raised if the char buffer is not present but is
169 requested.
170
Georg Brandlddbaa662006-06-04 21:56:52 +0000171- Patch #1346214: Statements like "if 0: suite" are now again optimized
172 away like they were in Python 2.4.
173
Georg Brandlb7c8f542006-05-27 12:30:25 +0000174- Builtin exceptions are now full-blown new-style classes instead of
175 instances pretending to be classes, which speeds up exception handling
176 by about 80% in comparison to 2.5a2.
177
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000178- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
179 Unicode 4.1.
180
Georg Brandlf4ef1162006-05-26 18:03:31 +0000181- Patch #921466: sys.path_importer_cache is now used to cache valid and
182 invalid file paths for the built-in import machinery which leads to
183 fewer open calls on startup.
184
Tim Peters696cf432006-05-24 21:10:40 +0000185- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
186 of-2 bases. The largest speedup is for inputs with about 1000 decimal
187 digits. Conversion from non-power-of-2 bases remains quadratic-time in
188 the number of input digits (it was and remains linear-time for bases
189 2, 4, 8, 16 and 32).
190
Tim Petersb713ec22006-05-23 18:45:30 +0000191- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
192 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
193 an integer close to ``sys.maxint``. This was repaired by patch
194 #1335972, which also gives a nice speedup.
195
Richard Jonescebbefc2006-05-23 18:28:17 +0000196- Patch #1337051: reduced size of frame objects.
197
198- PyErr_NewException now accepts a tuple of base classes as its
199 "base" parameter.
200
Richard Jones7c88dcc2006-05-23 10:37:38 +0000201- Patch #876206: function call speedup by retaining allocated frame
202 objects.
203
Georg Brandl7b90e162006-05-18 07:01:27 +0000204- Bug #1462152: file() now checks more thoroughly for invalid mode
205 strings and removes a possible "U" before passing the mode to the
206 C library function.
207
Neal Norwitz1004a532006-05-15 07:17:23 +0000208- Patch #1488312, Fix memory alignment problem on SPARC in unicode
209
Neal Norwitz373f0a72006-05-15 07:04:36 +0000210- Bug #1487966: Fix SystemError with conditional expression in assignment
211
Martin v. Löwis879768d2006-05-11 13:28:43 +0000212- WindowsError now has two error code attributes: errno, which carries
213 the error values from errno.h, and winerror, which carries the error
214 values from winerror.h. Previous versions put the winerror.h values
215 (from GetLastError()) into the errno attribute.
216
Martin v. Löwis77736712006-05-04 05:51:03 +0000217- Patch #1475845: Raise IndentationError for unexpected indent.
218
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000219- Patch #1479181: split open() and file() from being aliases for each other.
220
Tim Peters44bd9862006-06-01 13:49:23 +0000221- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
222 methods were always silently ignored by dictionaries when comparing keys.
223 They are now passed through (except when using the C API function
224 ``PyDict_GetItem()``, whose semantics did not change).
225
226- Bug #1456209: In some obscure cases it was possible for a class with a
227 custom ``__eq__()`` method to confuse dict internals when class instances
228 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
229 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000231Extension Modules
232-----------------
233
Trent Mick960a3f82006-06-28 20:30:41 +0000234- Bug #1295808: expat symbols should be namespaced in pyexpat
235
236- Patch #1462338: Upgrade pyexpat to expat 2.0.0
237
Brett Cannon6ee7d012006-06-08 16:23:04 +0000238- Change binascii.hexlify to accept a read-only buffer instead of only a char
239 buffer and actually follow its documentation.
240
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000241- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
242
Nick Coghlanc649ec52006-05-29 12:43:05 +0000243- Patch #1478788 (modified version): The functional extension module has
244 been renamed to _functools and a functools Python wrapper module added.
245 This provides a home for additional function related utilities that are
246 not specifically about functional programming. See PEP 309.
247
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000248- Patch #1493701: performance enhancements for struct module.
249
Georg Brandl378d5922006-05-17 14:26:50 +0000250- Patch #1490224: time.altzone is now set correctly on Cygwin.

253 copy() method.
254
Andrew MacIntyre92913322006-06-13 15:04:24 +0000255- Patch #1454481: thread stack size is now tunable at runtime for thread
256 enabled builds on Windows and systems with Posix threads support.
257
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000258- On Win32, os.listdir now supports arbitrarily-long Unicode path names
259 (up to the system limit of 32K characters).
260
261- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
262 As a result, these functions now raise WindowsError instead of OSError.
263
Tim Peters7a822da2006-05-25 21:50:17 +0000264- ``time.clock()`` on Win64 should use the high-performance Windows
265 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
266 Windows platforms).
267
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000268- Calling Tk_Init twice is refused if the first call failed as that
269 may deadlock.
270
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000271- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
272 accept it without potentially using an uninitialized pointer.
273
274- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
275 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
276 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000277
Gregory P. Smith372b5832006-06-05 18:48:21 +0000278- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000279 [pybsddb project SF patch number 1466734]
280
Gregory P. Smith372b5832006-06-05 18:48:21 +0000281- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
282 parameter is supplied. [SF pybsddb bug #1477863]
283
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000284- bsddb: the __len__ method of a DB object has been fixed to return correct
285 results. It could previously incorrectly return 0 in some cases.
286 Fixes SF bug 1493322 (pybsddb bug 1184012).
287
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000288- bsddb: the bsddb.dbtables Modify method now raises the proper error and
289 aborts the db transaction safely when a modifier callback fails.
290 Fixes SF python patch/bug #1408584.
291
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000292- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000293 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000294 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
295 database calls that would previously deadlock. [SF python bug #775414]
296
Vinay Sajip28e57612006-07-01 10:45:20 +0000297- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Vinay Sajip28e57612006-07-01 10:45:20 +0000310- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000311 Tkinter.BaseWidget.
312
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000313- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
314

316 classes.
317
Georg Brandl83cc0d02006-06-14 08:50:03 +0000318- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
319 mime.types file for determining MIME types.
320
Georg Brandl2605ca82006-06-14 06:08:31 +0000321- Bug #1339007: Shelf objects now don't raise an exception in their
322 __del__ method when initialization failed.
323
Martin v. Löwisd8251432006-06-14 05:21:04 +0000324- Patch #1455898: The MBCS codec now supports the incremental mode for
325 double-byte encodings.
326
Tim Peters43898b42006-06-14 04:09:25 +0000327- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
328 guarantee that adjacent triples in the return list always describe
329 non-adjacent blocks. Previously, a pair of matching blocks could end
330 up being described by multiple adjacent triples that formed a partition
331 of the matching pair.
332
Greg Ward0e0c9f42006-06-11 16:24:11 +0000333- Bug #1498146: fix optparse to handle Unicode strings in option help,
334 description, and epilog.
335
Greg Wardd1c797e2006-06-11 14:42:41 +0000336- Bug #1366250: minor optparse documentation error.
337
Greg Ward7f547402006-06-11 00:40:49 +0000338- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
339 clarify docs.
340
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000341- The wsgiref package has been added to the standard library.
342
Nick Coghlan676725d2006-06-08 13:54:49 +0000343- The functions update_wrapper() and wraps() have been added to the functools
344 module. These make it easier to copy relevant metadata from the original
345 function when writing wrapper functions.
346
Tim Petersd6a9eef2006-06-05 01:48:21 +0000347- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
348 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000349
Martin v. Löwis3f767792006-06-04 19:36:28 +0000350- Patch #1359618: Speed up charmap encoder by using a trie structure
351 for lookup.
352
Tim Petersd609b1a2006-06-02 23:22:51 +0000353- The functions in the ``pprint`` module now sort dictionaries by key
354 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
355 if and only if its display required more than one line, although that
356 wasn't documented. The new behavior increases predictability; e.g.,
357 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
358
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000359- Patch #1497027: try HTTP digest auth before basic auth in urllib2
360 (thanks for J. J. Lee).
361
Georg Brandl2b330372006-05-28 20:23:12 +0000362- Patch #1496206: improve urllib2 handling of passwords with respect to
363 default HTTP and HTTPS ports.
364
George Yoshidaf3c65de2006-05-28 16:39:09 +0000365- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
366
Bob Ippolito7298f272006-05-23 18:43:47 +0000367- Patch #1281707: speed up gzip.readline.
368
Georg Brandlb89316f2006-05-17 15:51:16 +0000369- Patch #1180296: Two new functions were added to the locale module:
370 format_string() to get the effect of "format % items" but locale-aware,
371 and currency() to format a monetary number with currency sign.
372
Georg Brandle3a25832006-05-17 14:56:04 +0000373- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
374 and several features added, such as speed and geometry control.
375
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000376- Patch #1488881: add support for external file objects in bz2 compressed
377 tarfiles.
378
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000379- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
380 stdout arguments, making it possible to redirect input and output
381 for remote debugging.
382
383- Patch #1484695: Update the tarfile module to version 0.8. This fixes
384 a couple of issues, notably handling of long file names using the
385 GNU LONGNAME extension.
386
387- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
388 new flag when ``name`` is already the name of an option flag.
389
390- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
391 package.
392
393- Patch #1472854: make the rlcompleter.Completer class usable on non-
394 UNIX platforms.
395
396- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
397
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000398- Bug #1472827: correctly escape newlines and tabs in attribute values in
399 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000429What's New in Python 2.5 alpha 2?
430=================================
431
432*Release date: 27-APR-2006*
433
434Core and builtins
435-----------------
436
Thomas Heller1b046642006-04-18 18:51:06 +0000437- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
438 by converting these apis from macros into exported functions again:
439
440 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
441 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
442 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
443 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
444 PyRun_String Py_CompileString
445
Martin v. Löwis45294a92006-04-18 06:24:08 +0000446- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
447
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000448- All uses of PyStructSequence_InitType have been changed to initialize
449 the type objects only once, even if the interpreter is initialized
450 multiple times.
451
Neal Norwitz61546162006-04-14 05:20:28 +0000452- Bug #1454485, array.array('u') could crash the interpreter. This was
453 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
454 to unicode when it didn't make sense. 'u#' now requires a unicode string.
455
456- Py_UNICODE is unsigned. It was always documented as unsigned, but
457 due to a bug had a signed value in previous versions.
458
Tim Peters3a5e8b12006-04-11 01:44:07 +0000459- Patch #837242: ``id()`` of any Python object always gives a positive
460 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
461 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000462 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000463 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000464
Tim Peters3a5e8b12006-04-11 01:44:07 +0000465 def __hash__(self):
466 return id(self) # WRONG
467
468 because a hash result must be a (short) Python int but it was always
469 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000470 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000471 was always usable as a hash value before this patch. That's no longer
472 necessarily so.
473
474- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000475 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000476 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000477 #1454844)
478
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000479- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
480 involving generators that have paused outside of any ``try`` or ``with``
481 blocks. (In 2.5a1, a paused generator that was part of a reference
482 cycle could not be garbage collected, regardless of whether it was
483 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000485Extension Modules

490
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000491- Bug #1467952: os.listdir() now correctly raises an error if readdir()
492 fails with an error condition.
493
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000494- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.

496- Bug #1117761: bsddb.*open() no longer raises an exception when using
497 the cachesize parameter.
498
499- Bug #1149413: bsddb.*open() no longer raises an exception when using
500 a temporary db (file=None) with the 'n' flag to truncate on open.
501
502- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
503 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000504
Armin Rigoa9017c32006-04-19 11:50:27 +0000505- Patch #1062014: AF_UNIX sockets under Linux have a special
506 abstract namespace that is now fully supported.
507
Anthony Baxter51bcb682006-04-05 14:51:42 +0000508Library
509-------
510
Tim Peters711bf302006-04-25 03:31:36 +0000511- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
512 a doctest to be skipped (the code is not run, and the expected output
513 or exception is ignored).
514
Nick Coghlanda2268f2006-04-24 04:37:15 +0000515- Fixed contextlib.nested to cope with exceptions being raised and
516 caught inside exit handlers.
517
Greg Wardab05edc2006-04-23 03:47:58 +0000518- Updated optparse module to Optik 1.5.1 (allow numeric constants in
519 hex, octal, or binary; add ``append_const`` action; keep going if
520 gettext cannot be imported; added ``OptionParser.destroy()`` method;
521 added ``epilog`` for better help generation).
522
Tim Peters21fbd572006-04-21 21:18:10 +0000523- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
524 called from a thread spawned as a side effect of importing a module.
525
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000526- The pydoc module now supports documenting packages contained in
527 .zip or .egg files.
528
529- The pkgutil module now has several new utility functions, such
530 as ``walk_packages()`` to support working with packages that are either
531 in the filesystem or zip files.
532
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000533- The mailbox module can now modify and delete messages from
534 mailboxes, in addition to simply reading them. Thanks to Gregory
535 K. Johnson for writing the code, and to the 2005 Google Summer of
536 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000537
Tim Petersc7605f22006-04-17 21:12:33 +0000538- The ``__del__`` method of class ``local`` in module ``_threading_local``
539 returned before accomplishing any of its intended cleanup.
540
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000541- Patch #790710: Add breakpoint command lists in pdb.
542
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000543- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000545- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
546
Anthony Baxtere29002c2006-04-12 12:07:31 +0000547- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
548 Windows. Bug #1469163.
549
Phillip J. Eby47032112006-04-11 01:07:43 +0000550- The warnings, linecache, inspect, traceback, site, and doctest modules
551 were updated to work correctly with modules imported from zipfiles or
552 via other PEP 302 __loader__ objects.
553
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000554- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis4be4e652006-04-17 19:25:49 +0000567- The Makefile now has a reindent target, which runs reindent.py on
568 the library.
569

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000574- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
575 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000576 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000577 CXX from --with-cxx-main, see description in README.
578

582
Tim Peters8931ff12006-05-13 23:28:20 +0000583- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
584 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

586
Anthony Baxter51bcb682006-04-05 14:51:42 +0000587Tests
588-----
589
Nick Coghlanda2268f2006-04-24 04:37:15 +0000590- test_contextlib now checks contextlib.nested can cope with exceptions
591 being raised and caught inside exit handlers.
592
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000593- test_cmd_line now checks operation of the -m and -c command switches
594
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000595- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
596 it separately and by hand. It also wasn't cleaning up its changes to
597 the current Decimal context.
598
Thomas Woutersabd08882006-04-26 15:53:30 +0000599- regrtest.py now has a -M option to run tests that test the new limits of
600 containers, on 64-bit architectures. Running these tests is only sensible
601 on 64-bit machines with more than two gigabytes of memory. The argument
602 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +0000613- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
614
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000615- PEP 343: Added Context Types section to the library reference
616 and attempted to bring other PEP 343 related documentation into
617 line with the implementation and/or python-dev discussions.
618
Tim Peters8dc73d22006-04-24 02:03:16 +0000619- Bug #1337990: clarified that ``doctest`` does not support examples

Nick Coghlan43832302006-04-23 17:04:07 +0000631- PEP 338: -m command line switch now delegates to runpy.run_module
632 allowing it to support modules in packages and zipfiles
633
Martin v. Löwisc661b882006-04-20 04:54:23 +0000634- On Windows, .DLL is not an accepted file name extension for
635 extension modules anymore; extensions are only found if they
636 end in .PYD.
637
Martin v. Löwisea62d252006-04-03 10:56:49 +0000638- Bug #1421664: sys.stderr.encoding is now set to the same value as
639 sys.stdout.encoding.
640
Neal Norwitz92e212f2006-04-03 04:48:37 +0000641- __import__ accepts keyword arguments.
642
Georg Brandlccadf842006-03-31 18:54:53 +0000643- Patch #1460496: round() now accepts keyword arguments.
644
Anthony Baxter262c00a2006-03-30 10:53:17 +0000645- Fixed bug #1459029 - unicode reprs were double-escaped.
646
Hye-Shik Changd478f342006-03-23 12:32:36 +0000647- Patch #1396919: The system scope threads are reenabled on FreeBSD
648 5.4 and later versions.
649
Neal Norwitze98ccf62006-03-23 05:39:47 +0000650- Bug #1115379: Compiling a Unicode string with an encoding declaration
651 now gives a SyntaxError.
652
Georg Brandlabd1ff82006-03-18 07:59:59 +0000653- Previously, Python code had no easy way to access the contents of a
654 cell object. Now, a ``cell_contents`` attribute has been added
655 (closes patch #1170323).
656
Tim Peterscf79aac2006-03-16 01:14:46 +0000657- Patch #1123430: Python's small-object allocator now returns an arena to
658 the system ``free()`` when all memory within an arena becomes unused
659 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
660 freed. Some applications will see a drop in virtual memory size now,
661 especially long-running applications that, from time to time, temporarily
662 use a large number of small objects. Note that when Python returns an
663 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000664 platform C library will in turn return that memory to the operating system.
665 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000666 appears to be effective at least on Microsoft C and gcc-based systems.
667 Thanks to Evan Jones for hard work and patience.
668
Georg Brandl533ff6f2006-03-08 18:09:27 +0000669- Patch #1434038: property() now uses the getter's docstring if there is
670 no "doc" argument given. This makes it possible to legitimately use
671 property() as a decorator to produce a read-only property.
672
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000673- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
674 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
675 of requiring an int or long in slicing and a few other contexts, enabling
676 other objects (e.g. Numeric Python's integers) to be used as slice indices.
677
Neal Norwitz995acdf2006-03-07 05:01:00 +0000678- Fixed various bugs reported by Coverity's Prevent tool.
679
Brett Cannonbf364092006-03-01 04:25:17 +0000680- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
681 new exception base class, BaseException, which has a new message attribute.
682 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
683 Raising a string exception now raises a DeprecationWarning.
684
Thomas Woutersfb609f42006-02-28 16:37:25 +0000685- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
686 explicitly relative, using 'from .module import name' to mean 'from the same
687 package as this module is in. Imports without dots still default to the
688 old relative-then-absolute, unless 'from __future__ import
689 absolute_import' is used.
690
Brett Cannona7446e32006-02-27 23:39:10 +0000691- Properly check if 'warnings' raises an exception (usually when a filter set
692 to "error" is triggered) when raising a warning for raising string
693 exceptions.
694
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000695- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000696 The name was removed from Include/code.h.
697
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000698- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000699
Guido van Rossum1968ad32006-02-25 22:38:04 +0000700- Patch 1433928:
701 - The copy module now "copies" function objects (as atomic objects).
702 - dict.__getitem__ now looks for a __missing__ hook before raising
703 KeyError.
704
Tim Peters84ef21c2006-02-28 20:39:06 +0000705- PEP 343: with statement implemented. Needs ``from __future__ import
706 with_statement``. Use of 'with' as a variable will generate a warning.
707 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000708 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000709 The following objects have __context__ methods:
710 - The built-in file type.
711 - The thread.LockType type.
712 - The following types defined by the threading module:
713 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
714 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000715
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000716- Fix the encodings package codec search function to only search
717 inside its own package. Fixes problem reported in patch #1433198.
718
719 Note: Codec packages should implement and register their own
720 codec search function. PEP 100 has the details.
721
Tim Peters9ea89d22006-06-04 03:26:02 +0000722- PEP 353: Using ``Py_ssize_t`` as the index type.
723
724- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
725 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
726 now allow Python to make use of memory blocks exceeding 2**32 bytes for
727 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
728 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000729
Neal Norwitzfc76d632006-01-10 06:03:13 +0000730- Patch #1400181, fix unicode string formatting to not use the locale.
731 This is how string objects work. u'%f' could use , instead of .
732 for the decimal point. Now both strings and unicode always use periods.
733
Neal Norwitz671b9e32006-01-09 07:07:12 +0000734- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
735 configure would break checking curses.h.
736
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000737- Bug #959576: The pwd module is now builtin. This allows Python to be
738 built on UNIX platforms without $HOME set.
739
Neal Norwitzc10978f2005-12-19 06:07:16 +0000740- Bug #1072182, fix some potential problems if characters are signed.
741
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000742- Bug #889500, fix line number on SyntaxWarning for global declarations.
743
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000744- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
745
Neal Norwitze7214a12005-12-18 05:03:17 +0000746- Support for converting hex strings to floats no longer works.
747 This was not portable. float('0x3') now raises a ValueError.
748
Barry Warsaw2a38a862005-12-18 01:27:35 +0000749- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000750 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000751 is now displayed in interactive prompt banner.
752
Georg Brandlfa166682005-12-17 21:45:17 +0000753- Implementation of PEP 341 - Unification of try/except and try/finally.
754 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000755 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000756
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000757- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
758 now encodes backslash correctly.
759
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000760- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
761
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000762- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000763 and long longs.
764
Neal Norwitz67715f02005-11-09 06:59:35 +0000765- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000766 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000767 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000768
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000769- Replaced most Unicode charmap codecs with new ones using the
770 new Unicode translate string feature in the builtin charmap
771 codec; the codecs were created from the mapping tables available
772 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
773 encodings now include a mapping for the Apple logo)
774
Tim Peterse3547fd2005-12-16 23:13:57 +0000775- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000776
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000777- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000778
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000779- A new AST parser implementation was completed. The abstract
780 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000781 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000782
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000783- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000784 The following code now raises a SyntaxError: foo(a = i for i in range(10))
785
Neal Norwitz708e51a2005-10-03 04:48:15 +0000786- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
787
Neal Norwitz11bd1192005-10-03 00:54:56 +0000788- SF Bug #887946: fix segfault when redirecting stdin from a directory.
789 Provide a warning when a directory is passed on the command line.
790
Neal Norwitz40d37812005-10-02 01:48:49 +0000791- Fix segfault with invalid coding.
792
793- SF bug #772896: unknown encoding results in MemoryError.
794
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000795- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000796 supported a __len__() method which evaluated to False when the iterator
797 was empty.
798
Guido van Rossum630db602005-09-20 18:49:54 +0000799- On 64-bit platforms, when __len__() returns a value that cannot be
800 represented as a C int, raise OverflowError.
801
Skip Montanarof8948ca2005-09-19 03:54:46 +0000802- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000803 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000804
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000805- SF bug #893549: parsing keyword arguments was broken with a few format
806 codes.
807
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000808- Changes donated by Elemental Security to make it work on AIX 5.3
809 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
810 bug #105470: test_pwd fails on 64bit system (Opteron).
811
Guido van Rossum539c6622005-09-14 17:49:54 +0000812- Changes donated by Elemental Security to make it work on HP-UX 11 on
813 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
814
Georg Brandl4550b8d2005-08-26 06:43:52 +0000815- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000816 (fixes bug #1119418).
817
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000818- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
819
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000820- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
821 exceptions that cause a function to exit.
822
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000823- The implementation of set() and frozenset() was revised to use its
824 own internal data structure. Memory consumption is reduced by 1/3
825 and there are modest speed-ups as well. The API is unchanged.
826
Tim Petersde7990b2005-07-17 23:45:23 +0000827- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
828
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000829- SF bug #1229429: PyObject_CallMethod failed to decrement some
830 reference counts in some error exit cases.
831
Tim Petersecc6e6a2005-07-10 22:30:55 +0000832- SF bug #1185883: Python's small-object memory allocator took over
833 a block managed by the platform C library whenever a realloc specified
834 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000835 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000836 portable way to copy data from the C-managed block into Python's
837 small-object space without risking a memory fault. Python's small-object
838 realloc now leaves such blocks under the control of the platform C
839 realloc.
840
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000841- SF bug #1232517: An overflow error was not detected properly when
842 attempting to convert a large float to an int in os.utime().
843
Raymond Hettinger3296e692005-06-29 23:29:56 +0000844- SF bug #1224347: hex longs now print with lowercase letters just
845 like their int counterparts.
846
Michael W. Hudson188d4362005-06-20 16:52:57 +0000847- SF bug #1163563: the original fix for bug #1010677 ("thread Module
848 Breaks PyGILState_Ensure()") broke badly in the case of multiple
849 interpreter states; back out that fix and do a better job (see
850 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
851 for a longer write-up of the problem).
852
Michael W. Hudsondf888462005-06-03 14:41:55 +0000853- SF patch #1180995: marshal now uses a binary format by default when
854 serializing floats.
855
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000856- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
857 the routines that promise to produce IEEE 754 binary representations
858 of floats now simply copy bytes around.
859
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000860- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
861 278.
862
Brett Cannonc3647ac2005-04-26 03:45:26 +0000863- patch #1109424: int, long, float, complex, and unicode now check for the
864 proper magic slot for type conversions when subclassed. Previously the
865 magic slot was ignored during conversion. Semantics now match the way
866 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000867 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000868 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000869 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000870
Barry Warsawc8d907c2005-04-19 23:43:40 +0000871- Descriptors defined in C with a PyGetSetDef structure, where the setter is
872 NULL, now raise an AttributeError when attempting to set or delete the
873 attribute. Previously a TypeError was raised, but this was inconsistent
874 with the equivalent pure-Python implementation.
875
Michael W. Hudson774479c2005-04-18 08:46:17 +0000876- It is now safe to call PyGILState_Release() before
877 PyEval_InitThreads() (note that if there is reason to believe there
878 are multiple threads around you still must call PyEval_InitThreads()
879 before using the Python API; this fix is for extension modules that
880 have no way of knowing if Python is multi-threaded yet).
881
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000882- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
883 disabled caused a crash.
884
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000885- Bug #1165306: instancemethod_new allowed the creation of a method
886 with im_class == im_self == NULL, which caused a crash when called.
887
Tim Petersecc6e6a2005-07-10 22:30:55 +0000888- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000889 fixes the crash seen in bug #1165761
890
Raymond Hettinger96229b12005-03-11 06:49:40 +0000891- Added two new builtins, any() and all().
892
Brett Cannon409d8f22005-03-05 06:47:57 +0000893- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000894 (e.g., ``class C(): pass`` is no longer a syntax error).
895 Patch #1176012 added support to the 'parser' module and 'compiler' package
896 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000897
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000898- Patch #1115086: Support PY_LONGLONG in structmember.
899
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000900- Bug #1155938: new style classes did not check that __init__() was
901 returning None.
902

Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000912 an ferror() call.
913
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000914- min() and max() now support key= arguments with the same meaning as in

Jeremy Hyltonab630502005-02-04 18:44:06 +0000925- The parser did not complain about future statements in illegal

Tim Petersf4e69282006-02-27 17:15:31 +0000933- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
934 current thread state when the auto-GIL-state machinery knows about
935 it (since the thread state is being deleted, continuing to remember it
936 can't help, but can hurt if another thread happens to get created with
937 the same thread id).

1127-------
1128
Nick Coghlan43832302006-04-23 17:04:07 +00001129- PEP 338: new module runpy defines a run_module function to support
1130 executing modules which provide access to source code or a code object
1131 via the PEP 302 import mechanisms.
1132
Anthony Baxter93f5b932006-04-03 08:05:07 +00001133- The email module's parsedate_tz function now sets the daylight savings

1141 in attribute values.
1142
Anthony Baxterc51ee692006-04-01 00:57:31 +00001143- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001144 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001145 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001146 module will not be built.
1147
Tim Petersc17976e2006-04-01 00:26:53 +00001148- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1149 aren't officially supported here, and trying to use them will probably
1150 raise an exception some day. But dicts have been allowed, and "mostly
1151 worked", so support for them won't go away without warning.
1152
Georg Brandl338ef7d2006-03-31 18:42:16 +00001153- Bug #1445068: getpass.getpass() can now be given an explicit stream

1171
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001172- email 4.0 package now integrated. This is largely the same as the email 3.0
1173 package that was included in Python 2.3, except that PEP 8 module names are
1174 now used (e.g. mail.message instead of email.Message). The MIME classes
1175 have been moved to a subpackage (e.g. email.mime.text instead of
1176 email.MIMEText). The old names are still supported for now. Several
1177 deprecated Message methods have been removed and lots of bugs have been
1178 fixed. More details can be found in the email package documentation.

Walter Dörwald40108c92006-03-27 08:15:44 +00001180- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1181 (a subclass of tuple) that provides incremental decoders and encoders
1182 (a way to use stateful codecs without the stream API). Python functions
1183 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1184 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1185 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001187- Patch #1359365: Calling next() on a closed StringIO.String object raises
1188 a ValueError instead of a StopIteration now (like file and cString.String do).
1189 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1190 called before (like file and StringIO.StringIO do).

1265 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1266 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1267 Ronald L. Rivest offered this advice for Python:
1268
1269 "The consensus of researchers in this area (at least as
1270 expressed at the NIST Hash Function Workshop 10/31/05),
1271 is that SHA-256 is a good choice for the time being, but
1272 that research should continue, and other alternatives may
1273 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001274

Guido van Rossumd0641422005-02-03 15:01:24 +00001434- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1435 disables recursive traversal through instance attributes, which can
1436 be exploited in various ways.
1437
Tim Peterse3547fd2005-12-16 23:13:57 +00001438- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001439 flags on the HTTP listening socket.
1440
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001441- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1442 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1443
Tim Peterse3547fd2005-12-16 23:13:57 +00001444- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001445 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1446
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001447- Bug #1110478: Revert os.environ.update to do putenv again.
1448
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001449- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1450
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001451- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1452
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001453- Enhancements to the csv module:
1454
1455 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001456 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001457 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001458 + Dialect parameter parsing has been re-implemented to improve error
1459 reporting.
1460 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1461 dictates.
1462 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001463 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001464 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001465 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1466 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001467 + reader now allows \r characters to be quoted (previously it only allowed
1468 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001469 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001470 + Dialect classes passed to the module are no longer instantiated by
1471 the module before being parsed (the former validation scheme required
1472 this, but the mechanism was unreliable).
1473 + The dialect registry now contains instances of the internal
1474 C-coded dialect type, rather than references to python objects.
1475 + the internal c-coded dialect type is now immutable.
1476 + register_dialect now accepts the same keyword dialect specifications
1477 as the reader and writer, allowing the user to register dialects
1478 without first creating a dialect class.
1479 + a configurable limit to the size of parsed fields has been added -
1480 previously, an unmatched quote character could result in the entire
1481 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001482 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001483 the parser field size limit (returning the former limit). The initial
1484 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001485 + A line_num attribute has been added to the reader object, which tracks
1486 the number of lines read from the source iterator. This is not
1487 the same as the number of records returned, as records can span
1488 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001489 + reader and writer objects were not being registered with the cyclic-GC.
1490 This has been fixed.
1491
Brett Cannone6539c42005-01-08 02:43:53 +00001492- _DummyThread objects in the threading module now delete self.__block that is
1493 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1494 lock primitives tend to be limited in number and thus should not be wasted on
1495 a _DummyThread object. Fixes bug #1089632.
1496
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001497- The imghdr module now detects Exif files.
1498
Raymond Hettinger6065d322004-12-20 23:51:53 +00001499- StringIO.truncate() now correctly adjusts the size attribute.
1500 (Bug #951915).
1501
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001502- locale.py now uses an updated locale alias table (built using
1503 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1504 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001505 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001506
Raymond Hettinger3557f422004-12-07 12:02:02 +00001507- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1508
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001509- the pickle module no longer accepts the deprecated None option in the
1510 args tuple returned by __reduce__().
1511
Brett Cannon84667c02004-12-07 03:25:18 +00001512- optparse now optionally imports gettext. This allows its use in setup.py.
1513
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001514- the pickle module no longer uses the deprecated bin parameter.
1515
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001516- the shelve module no longer uses the deprecated binary parameter.
1517
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001518- the pstats module no longer uses the deprecated ignore() method.
1519
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001520- the filecmp module no longer uses the deprecated use_statcache argument.
1521
Raymond Hettinger664347b2004-12-04 21:21:53 +00001522- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1523 extended or overridden by subclasses. Formerly, the subclassed method would
1524 be ignored by the rest of the module. (Bug #1078905).
1525
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001526- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001527 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001528
Walter Dörwald36733692004-12-22 12:50:50 +00001529- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1530 once when a size argument is given. This prevents a buffer overflow in the
1531 tokenizer with very long source lines.
1532
Barry Warsaw538561e2006-01-01 21:48:54 +00001533- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1534 immediately after creating the object, without any intervening
1535 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001536
Skip Montanaro05885812005-01-16 20:48:27 +00001537- The reconvert.quote function can now emit triple-quoted strings. The
1538 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001539
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001540- ``UserString.MutableString`` now supports negative indices in
1541 ``__setitem__`` and ``__delitem__``
1542
Greg Ward40407942005-03-05 02:53:17 +00001543- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1544 correctly.
1545
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001546- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1547 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1548 character even if the user has passed a size parameter to get a proper
1549 line ending. Remove the special handling of a "\r\n" that has been split
1550 between two lines.
1551
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001552- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1553 about illegal code points. The codec now supports PEP 293 style error
1554 handlers.
1555
Walter Dörwald78a78b02005-09-01 12:04:29 +00001556- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001557 from the input stream, so that the output is a byte string in the correct
1558 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001559
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001560- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1561 considering it exactly like a '*'.
1562
Walter Dörwald007f8df2005-10-09 19:42:27 +00001563- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1564 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001565
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001566- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1567
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001568- Patch #1413711: Certain patterns of differences were making difflib
1569 touch the recursion limit.
1570
Walter Dörwald58917a62006-03-31 15:26:22 +00001571- Bug #947906: An object oriented interface has been added to the calendar
1572 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001573 called as a script (e.g. via ``python -mcalendar``). Localized month and
1574 weekday names can be ouput (even if an exotic encoding is used) using
1575 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001576
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001577Build
1578-----
1579
Neal Norwitz602d3392006-03-31 08:21:40 +00001580- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1581 by using -mieee gcc option.
1582

1584
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001585- Build support for Win64-AMD64 was added.
1586
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001587- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1588
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001589- Patch #881820: look for openpty and forkpty also in libbsd.
1590
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001591- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1592 The zlib module is now builtin on Windows.
1593
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001594- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1595
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001596- Bug #1189330: configure did not correctly determine the necessary
1597 value of LINKCC if python was built with GCC 4.0.
1598
Trent Mick8321b422005-07-26 02:29:21 +00001599- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1600 vulnerability in zlib 1.2.1 and 1.2.2.
1601
Brett Cannon08cd5982005-04-24 22:26:38 +00001602- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1603 flags that change binary compatibility. Changes were also made to
1604 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001605 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001606
Bob Ippolitoed233462005-03-29 13:47:59 +00001607- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1608 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1609 no longer exists). This configure patch makes things right.
1610
Martin v. Löwise2713be2005-03-08 15:03:08 +00001611- Bug #1158607: Build with --disable-unicode again.
1612
Brett Cannon46d96232005-02-16 00:07:19 +00001613- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1614 defined. Discovered as a result of not being able to build on OS X.
1615
Brett Cannon516592f2004-12-07 00:42:59 +00001616- setup.py now uses the directories specified in LDFLAGS using the -L option
1617 and in CPPFLAGS using the -I option for adding library and include
1618 directories, respectively, for compiling extension modules against. This has
1619 led to the core being compiled using the values in CPPFLAGS. It also removes
1620 the need for the special-casing of both DarwinPorts and Fink for darwin since
1621 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1622 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1623 Fink, ``-I/opt/local/include`` for DarwinPorts).
1624
Brett Cannon43802422005-02-10 20:48:03 +00001625- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1626 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1627 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1628 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001630C API
1631-----
1632
Tim Petersc9d78aa2006-03-26 23:27:58 +00001633- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1634 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1635 is obtained via the ``PyObject_`` family, it must be released via the
1636 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1637 always been officially true, but when Python's small-object allocator was
1638 introduced, an attempt was made to cater to a few extension modules
1639 discovered at the time that obtained memory via ``PyObject_New`` but
1640 released it via ``PyMem_DEL``. It's years later, and if such code still
1641 exists it will fail now (probably with segfaults, but calling wrong
1642 low-level memory management functions can yield many symptoms).
1643
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001644- Added a C API for set and frozenset objects.
1645
Raymond Hettinger66517482004-12-03 11:45:13 +00001646- Removed PyRange_New().
1647
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001648- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1649 mapping argument now. This string is used as a mapping table. Byte values
1650 greater than the length of the string and 0xFFFE are treated as undefined
1651 mappings.
