15- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
16 again. Fixing this problem required changing the .pyc magic number.
17 This means that .pyc files generated before 2.5c1 will be regenerated.

32-----------------
33
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000034- Bug #1441486: The literal representation of -(sys.maxint - 1)
35 again evaluates to a int object, not a long.
36
Neil Schemenauer0e07b602006-07-09 16:16:34 +000037- Bug #1501934: The scope of global variables that are locally assigned
38 using augmented assignment is now correctly determined.
39
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000040- Bug #927248: Recursive method-wrapper objects can now safely
41 be released.
42
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000043- Bug #1417699: Reject locale-specific decimal point in float()
44 and atof().
45
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000046- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
47 omit a default "error" argument for NULL pointer. This allows
48 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000049
Neal Norwitzfb48afa2006-07-08 05:31:37 +000050- Bug #1519018: 'as' is now validated properly in import statements.
51
Neal Norwitz28746ab2006-07-09 22:14:42 +000052- On 64 bit systems, int literals that use less than 64 bits are
53 now ints rather than longs.
54
Neal Norwitzed657552006-07-10 00:04:44 +000055- Bug #1512814, Fix incorrect lineno's when code at module scope
56 started after line 256.
57
Tim Peters32a83612006-07-10 21:08:24 +000058- New function ``sys._current_frames()`` returns a dict mapping thread
59 id to topmost thread stack frame. This is for expert use, and is
60 especially useful for debugging application deadlocks. The functionality
61 was previously available in Fazal Majid's ``threadframe`` extension
62 module, but it wasn't possible to do this in a wholly threadsafe way from
63 an extension.

67
Martin v. Löwis06c68b82006-07-10 22:11:28 +000068- Patch #1519566: Update turtle demo, make begin_fill idempotent.
69

Martin v. Löwis8d656812006-07-10 07:23:48 +000071 environment variable to be set in order to the SDK environment
72 for finding the compiler, include files, etc.
73
Martin v. Löwis388a8c22006-07-06 19:28:03 +000074- Bug #1515998: Properly generate logical ids for files in bdist_msi.
75
Nick Coghlan2d792252006-07-06 13:47:18 +000076- warnings.py now ignores ImportWarning by default
77
Thomas Woutersadd19112006-07-05 11:03:49 +000078- string.Template() now correctly handles tuple-values. Previously,
79 multi-value tuples would raise an exception and single-value tuples would
80 be treated as the value they contain, instead.
81
Martin v. Löwisede77f52006-07-03 13:01:35 +000082- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
83 even if some data are received.
84
Martin v. Löwis45482392006-07-03 12:28:58 +000085- Bug #1267547: Put proper recursive setup.py call into the

Martin v. Löwis2b88f632006-07-03 10:19:49 +000092 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000093
Martin v. Löwisbd39c032006-07-03 09:44:00 +000094- Bug #1514703: Only setup canvas window in turtle when the canvas
95 is created.
96
Martin v. Löwis7596e832006-07-01 15:33:37 +000097- Bug #1513223: .close() of a _socketobj now releases the underlying
98 socket again, which then gets closed as it becomes unreferenced.
99
Fred Drake10497c82006-06-29 02:57:48 +0000100- Bug #1504333: Make sgmllib support angle brackets in quoted
101 attribute values.
102
103- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
104 sgmllib ('[' and ']' were not accepted).
105
Georg Brandl1be63af2006-06-28 20:23:25 +0000106- Fix a bug in the turtle module's end_fill function.
107
Brett Cannon53ab5b72006-06-22 16:49:14 +0000108- Bug #1510580: The 'warnings' module improperly required that a Warning
109 category be either a types.ClassType and a subclass of Warning. The proper
110 check is just that it is a subclass with Warning as the documentation states.
111
Georg Brandlad29e632006-06-21 17:45:17 +0000112- The compiler module now correctly compiles the new try-except-finally
113 statement (bug #1509132).
114
Neal Norwitz60373cd2006-06-22 06:30:50 +0000115- The wsgiref package is now installed properly on Unix.
116
Vinay Sajip28e57612006-07-01 10:45:20 +0000117- A bug was fixed in logging.config.fileConfig() which caused a crash on
118 shutdown when fileConfig() was called multiple times.
119
Gerhard Häring762fbd32006-07-02 17:48:30 +0000120- The sqlite3 module did cut off data from the SQLite database at the first
121 null character before sending it to a custom converter. This has been fixed
122 now.
123
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000124Extension Modules
125-----------------
126
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000127- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
128 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
129 The patch makes sockets use poll() internally where available.
130
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000131- Assigning None to pointer type fields in ctypes structures possible
132 overwrote the wrong fields, this is fixed now.
133
134- Fixed a segfault in _ctypes when ctypes.wintypes were imported
135 on non-Windows platforms.
136
137- Bug #1518190: The ctypes.c_void_p constructor now accepts any
138 integer or long, without range checking.
139
140- Patch #1517790: It is now possible to use custom objects in the ctypes
141 foreign function argtypes sequence as long as they provide a from_param
142 method, no longer is it required that the object is a ctypes type.
143
144- The '_ctypes' extension module now works when Python is configured
145 with the --without-threads option.
146
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000147- Bug #1513646: os.access on Windows now correctly determines write
148 access, again.
149
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000150- Bug #1512695: cPickle.loads could crash if it was interrupted with
151 a KeyboardInterrupt.
152
Neal Norwitza12aa882006-07-06 06:45:08 +0000153- Bug #1296433: parsing XML with a non-default encoding and
154 a CharacterDataHandler could crash the interpreter in pyexpat.
155
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000156- Patch #1516912: improve Modules support for OpenVMS.
157
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000158Build
159-----
160
Tim Peters32a83612006-07-10 21:08:24 +0000161- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000162 Previously, the slight difference could cause compilation errors of the
163 'zlib' module on systems with more than one version of zlib.
164
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000165- The MSI compileall step was fixed to also support a TARGETDIR
166 with spaces in it.
167
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000168- Bug #1517388: sqlite3.dll is now installed on Windows independent
169 of Tcl/Tk.
170
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000171- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000172 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000174Tests
175-----
176
177- Call os.waitpid() at the end of tests that spawn child processes in order
178 to minimize resources (zombies).
179
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000180Documentation
181-------------
182
Nick Coghlan2d792252006-07-06 13:47:18 +0000183- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
184 documentation for the warnings module.
185
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000186- Patch #1509163: MS Toolkit Compiler no longer available.
187
Neal Norwitz56640df2006-07-10 02:36:41 +0000188- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000194
195Core and builtins
196-----------------
197
Georg Brandla56b9152006-06-19 06:35:54 +0000198- Patch #1507676: Error messages returned by invalid abstract object operations
199 (such as iterating over an integer) have been improved and now include the
200 type of the offending object to help with debugging.
201
Brett Cannonea3912b2006-06-13 21:46:41 +0000202- Bug #992017: A classic class that defined a __coerce__() method that returned
203 its arguments swapped would infinitely recurse and segfault the interpreter.
204
Neal Norwitz909eb122006-06-12 02:13:21 +0000205- Fix the socket tests so they can be run concurrently.
206
Neal Norwitzb9845e72006-06-12 02:11:18 +0000207- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000208 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000209
Brett Cannon22565aa2006-06-09 22:31:23 +0000210- Bug #532646: object.__call__() will continue looking for the __call__
211 attribute on objects until one without one is found. This leads to recursion
212 when you take a class and set its __call__ attribute to an instance of the
213 class. Originally fixed for classic classes, but this fix is for new-style.
214 Removes the infinite_rec_3 crasher.
215
Georg Brandl24250812006-06-09 18:45:48 +0000216- The string and unicode methods startswith() and endswith() now accept
217 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
218
Brett Cannonde3b0522006-06-08 17:00:45 +0000219- Buffer objects, at the C level, never used the char buffer
220 implementation even when the char buffer for the wrapped object was
221 explicitly requested (originally returned the read or write buffer).
222 Now a TypeError is raised if the char buffer is not present but is
223 requested.
224
Georg Brandlddbaa662006-06-04 21:56:52 +0000225- Patch #1346214: Statements like "if 0: suite" are now again optimized
226 away like they were in Python 2.4.
227
Georg Brandlb7c8f542006-05-27 12:30:25 +0000228- Builtin exceptions are now full-blown new-style classes instead of
229 instances pretending to be classes, which speeds up exception handling
230 by about 80% in comparison to 2.5a2.
231
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000232- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
233 Unicode 4.1.
234
Georg Brandlf4ef1162006-05-26 18:03:31 +0000235- Patch #921466: sys.path_importer_cache is now used to cache valid and
236 invalid file paths for the built-in import machinery which leads to
237 fewer open calls on startup.
238
Tim Peters696cf432006-05-24 21:10:40 +0000239- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
240 of-2 bases. The largest speedup is for inputs with about 1000 decimal
241 digits. Conversion from non-power-of-2 bases remains quadratic-time in
242 the number of input digits (it was and remains linear-time for bases
243 2, 4, 8, 16 and 32).
244
Tim Petersb713ec22006-05-23 18:45:30 +0000245- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
246 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
247 an integer close to ``sys.maxint``. This was repaired by patch
248 #1335972, which also gives a nice speedup.
249
Richard Jonescebbefc2006-05-23 18:28:17 +0000250- Patch #1337051: reduced size of frame objects.
251
252- PyErr_NewException now accepts a tuple of base classes as its
253 "base" parameter.
254
Richard Jones7c88dcc2006-05-23 10:37:38 +0000255- Patch #876206: function call speedup by retaining allocated frame
256 objects.
257
Georg Brandl7b90e162006-05-18 07:01:27 +0000258- Bug #1462152: file() now checks more thoroughly for invalid mode
259 strings and removes a possible "U" before passing the mode to the
260 C library function.
261
Neal Norwitz1004a532006-05-15 07:17:23 +0000262- Patch #1488312, Fix memory alignment problem on SPARC in unicode
263
Neal Norwitz373f0a72006-05-15 07:04:36 +0000264- Bug #1487966: Fix SystemError with conditional expression in assignment
265
Martin v. Löwis879768d2006-05-11 13:28:43 +0000266- WindowsError now has two error code attributes: errno, which carries
267 the error values from errno.h, and winerror, which carries the error
268 values from winerror.h. Previous versions put the winerror.h values
269 (from GetLastError()) into the errno attribute.
270
Martin v. Löwis77736712006-05-04 05:51:03 +0000271- Patch #1475845: Raise IndentationError for unexpected indent.
272
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000273- Patch #1479181: split open() and file() from being aliases for each other.
274
Tim Peters44bd9862006-06-01 13:49:23 +0000275- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
276 methods were always silently ignored by dictionaries when comparing keys.
277 They are now passed through (except when using the C API function
278 ``PyDict_GetItem()``, whose semantics did not change).
279
280- Bug #1456209: In some obscure cases it was possible for a class with a
281 custom ``__eq__()`` method to confuse dict internals when class instances
282 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
283 No, you don't have any code that did this ;-)

286-----------------
287
Trent Mick960a3f82006-06-28 20:30:41 +0000288- Bug #1295808: expat symbols should be namespaced in pyexpat
289
290- Patch #1462338: Upgrade pyexpat to expat 2.0.0
291
Brett Cannon6ee7d012006-06-08 16:23:04 +0000292- Change binascii.hexlify to accept a read-only buffer instead of only a char
293 buffer and actually follow its documentation.
294
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000295- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
296
Nick Coghlanc649ec52006-05-29 12:43:05 +0000297- Patch #1478788 (modified version): The functional extension module has
298 been renamed to _functools and a functools Python wrapper module added.
299 This provides a home for additional function related utilities that are
300 not specifically about functional programming. See PEP 309.
301
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000302- Patch #1493701: performance enhancements for struct module.
303

305
Georg Brandl8d3342b2006-05-16 07:38:27 +0000306- Patch #1435422: zlib's compress and decompress objects now have a
307 copy() method.
308
Andrew MacIntyre92913322006-06-13 15:04:24 +0000309- Patch #1454481: thread stack size is now tunable at runtime for thread
310 enabled builds on Windows and systems with Posix threads support.
311
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000312- On Win32, os.listdir now supports arbitrarily-long Unicode path names
313 (up to the system limit of 32K characters).
314
315- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
316 As a result, these functions now raise WindowsError instead of OSError.
317
Tim Peters7a822da2006-05-25 21:50:17 +0000318- ``time.clock()`` on Win64 should use the high-performance Windows
319 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
320 Windows platforms).
321
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000322- Calling Tk_Init twice is refused if the first call failed as that
323 may deadlock.
324
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000325- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
326 accept it without potentially using an uninitialized pointer.
327
328- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
329 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smithf0547d02006-06-05 17:38:04 +0000333 [pybsddb project SF patch number 1466734]
334
Gregory P. Smith372b5832006-06-05 18:48:21 +0000335- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
336 parameter is supplied. [SF pybsddb bug #1477863]
337
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000338- bsddb: the __len__ method of a DB object has been fixed to return correct
339 results. It could previously incorrectly return 0 in some cases.
340 Fixes SF bug 1493322 (pybsddb bug 1184012).
341
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000342- bsddb: the bsddb.dbtables Modify method now raises the proper error and
343 aborts the db transaction safely when a modifier callback fails.
344 Fixes SF python patch/bug #1408584.
345
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000346- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000347 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000348 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
349 database calls that would previously deadlock. [SF python bug #775414]

379 double-byte encodings.
380
Tim Peters43898b42006-06-14 04:09:25 +0000381- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
382 guarantee that adjacent triples in the return list always describe
383 non-adjacent blocks. Previously, a pair of matching blocks could end
384 up being described by multiple adjacent triples that formed a partition
385 of the matching pair.

394
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000395- The wsgiref package has been added to the standard library.
396
Nick Coghlan676725d2006-06-08 13:54:49 +0000397- The functions update_wrapper() and wraps() have been added to the functools
398 module. These make it easier to copy relevant metadata from the original
399 function when writing wrapper functions.
400
Tim Petersd6a9eef2006-06-05 01:48:21 +0000401- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
402 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.

Martin v. Löwis3f767792006-06-04 19:36:28 +0000404- Patch #1359618: Speed up charmap encoder by using a trie structure
405 for lookup.
406
Tim Petersd609b1a2006-06-02 23:22:51 +0000407- The functions in the ``pprint`` module now sort dictionaries by key
408 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
409 if and only if its display required more than one line, although that
410 wasn't documented. The new behavior increases predictability; e.g.,
411 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
412
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000413- Patch #1497027: try HTTP digest auth before basic auth in urllib2

424 format_string() to get the effect of "format % items" but locale-aware,
425 and currency() to format a monetary number with currency sign.
426
Georg Brandle3a25832006-05-17 14:56:04 +0000427- Patch #1486962: Several bugs in the turtle Tk demo module were fixed

431 tarfiles.
432
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000433- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
434 stdout arguments, making it possible to redirect input and output
435 for remote debugging.
436
437- Patch #1484695: Update the tarfile module to version 0.8. This fixes
438 a couple of issues, notably handling of long file names using the
439 GNU LONGNAME extension.
440
441- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
442 new flag when ``name`` is already the name of an option flag.
443
444- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
445 package.

487
488Core and builtins
489-----------------
490
Thomas Heller1b046642006-04-18 18:51:06 +0000491- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
492 by converting these apis from macros into exported functions again:
493
494 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
495 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
496 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
497 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
498 PyRun_String Py_CompileString
499
Martin v. Löwis45294a92006-04-18 06:24:08 +0000500- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
501
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000502- All uses of PyStructSequence_InitType have been changed to initialize
503 the type objects only once, even if the interpreter is initialized
504 multiple times.
505
Neal Norwitz61546162006-04-14 05:20:28 +0000506- Bug #1454485, array.array('u') could crash the interpreter. This was
507 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
508 to unicode when it didn't make sense. 'u#' now requires a unicode string.
509
510- Py_UNICODE is unsigned. It was always documented as unsigned, but
511 due to a bug had a signed value in previous versions.
512
Tim Peters3a5e8b12006-04-11 01:44:07 +0000513- Patch #837242: ``id()`` of any Python object always gives a positive
514 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
515 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000516 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000517 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000518
Tim Peters3a5e8b12006-04-11 01:44:07 +0000519 def __hash__(self):
520 return id(self) # WRONG
521
522 because a hash result must be a (short) Python int but it was always
523 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000524 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000525 was always usable as a hash value before this patch. That's no longer
526 necessarily so.
527
528- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000529 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000530 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000531 #1454844)
532
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000533- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
534 involving generators that have paused outside of any ``try`` or ``with``
535 blocks. (In 2.5a1, a paused generator that was part of a reference
536 cycle could not be garbage collected, regardless of whether it was
537 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +0000565- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
566 a doctest to be skipped (the code is not run, and the expected output
567 or exception is ignored).
568

573 hex, octal, or binary; add ``append_const`` action; keep going if
574 gettext cannot be imported; added ``OptionParser.destroy()`` method;
575 added ``epilog`` for better help generation).
576
Tim Peters21fbd572006-04-21 21:18:10 +0000577- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
578 called from a thread spawned as a side effect of importing a module.
579
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000580- The pydoc module now supports documenting packages contained in
581 .zip or .egg files.
582
583- The pkgutil module now has several new utility functions, such
584 as ``walk_packages()`` to support working with packages that are either
585 in the filesystem or zip files.
586
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000587- The mailbox module can now modify and delete messages from
588 mailboxes, in addition to simply reading them. Thanks to Gregory
589 K. Johnson for writing the code, and to the 2005 Google Summer of
590 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000591
Tim Petersc7605f22006-04-17 21:12:33 +0000592- The ``__del__`` method of class ``local`` in module ``_threading_local``
593 returned before accomplishing any of its intended cleanup.
594

602 Windows. Bug #1469163.
603
Phillip J. Eby47032112006-04-11 01:07:43 +0000604- The warnings, linecache, inspect, traceback, site, and doctest modules

Tim Peters8931ff12006-05-13 23:28:20 +0000637- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
638 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
639 and "%zu" for unsigned integers of type ``size_t``.

642-----
643
Nick Coghlanda2268f2006-04-24 04:37:15 +0000644- test_contextlib now checks contextlib.nested can cope with exceptions
645 being raised and caught inside exit handlers.
646
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000647- test_cmd_line now checks operation of the -m and -c command switches
648
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000649- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
650 it separately and by hand. It also wasn't cleaning up its changes to
651 the current Decimal context.
652
Thomas Woutersabd08882006-04-26 15:53:30 +0000653- regrtest.py now has a -M option to run tests that test the new limits of
654 containers, on 64-bit architectures. Running these tests is only sensible
655 on 64-bit machines with more than two gigabytes of memory. The argument
656 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000664Documentation
665-------------
666
Tim Petersb06d28c2006-05-12 01:57:59 +0000667- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
668
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000669- PEP 343: Added Context Types section to the library reference
670 and attempted to bring other PEP 343 related documentation into
671 line with the implementation and/or python-dev discussions.
672
Tim Peters8dc73d22006-04-24 02:03:16 +0000673- Bug #1337990: clarified that ``doctest`` does not support examples
674 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000677What's New in Python 2.5 alpha 1?
678=================================
679
Anthony Baxterebed3f62006-04-03 15:03:44 +0000680*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000681
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000682Core and builtins
683-----------------
684
Nick Coghlan43832302006-04-23 17:04:07 +0000685- PEP 338: -m command line switch now delegates to runpy.run_module
686 allowing it to support modules in packages and zipfiles
687
Martin v. Löwisc661b882006-04-20 04:54:23 +0000688- On Windows, .DLL is not an accepted file name extension for
689 extension modules anymore; extensions are only found if they
690 end in .PYD.
691
Martin v. Löwisea62d252006-04-03 10:56:49 +0000692- Bug #1421664: sys.stderr.encoding is now set to the same value as
693 sys.stdout.encoding.
694
Neal Norwitz92e212f2006-04-03 04:48:37 +0000695- __import__ accepts keyword arguments.
696
Georg Brandlccadf842006-03-31 18:54:53 +0000697- Patch #1460496: round() now accepts keyword arguments.
698
Anthony Baxter262c00a2006-03-30 10:53:17 +0000699- Fixed bug #1459029 - unicode reprs were double-escaped.
700
Hye-Shik Changd478f342006-03-23 12:32:36 +0000701- Patch #1396919: The system scope threads are reenabled on FreeBSD
702 5.4 and later versions.
703
Neal Norwitze98ccf62006-03-23 05:39:47 +0000704- Bug #1115379: Compiling a Unicode string with an encoding declaration
705 now gives a SyntaxError.
706
Georg Brandlabd1ff82006-03-18 07:59:59 +0000707- Previously, Python code had no easy way to access the contents of a
708 cell object. Now, a ``cell_contents`` attribute has been added
709 (closes patch #1170323).
710
Tim Peterscf79aac2006-03-16 01:14:46 +0000711- Patch #1123430: Python's small-object allocator now returns an arena to
712 the system ``free()`` when all memory within an arena becomes unused
713 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
714 freed. Some applications will see a drop in virtual memory size now,
715 especially long-running applications that, from time to time, temporarily
716 use a large number of small objects. Note that when Python returns an
717 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000718 platform C library will in turn return that memory to the operating system.
719 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000720 appears to be effective at least on Microsoft C and gcc-based systems.
721 Thanks to Evan Jones for hard work and patience.
722
Georg Brandl533ff6f2006-03-08 18:09:27 +0000723- Patch #1434038: property() now uses the getter's docstring if there is
724 no "doc" argument given. This makes it possible to legitimately use
725 property() as a decorator to produce a read-only property.
726
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000727- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
728 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
729 of requiring an int or long in slicing and a few other contexts, enabling
730 other objects (e.g. Numeric Python's integers) to be used as slice indices.
731
Neal Norwitz995acdf2006-03-07 05:01:00 +0000732- Fixed various bugs reported by Coverity's Prevent tool.
733
Brett Cannonbf364092006-03-01 04:25:17 +0000734- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
735 new exception base class, BaseException, which has a new message attribute.
736 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
737 Raising a string exception now raises a DeprecationWarning.
738
Thomas Woutersfb609f42006-02-28 16:37:25 +0000739- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
740 explicitly relative, using 'from .module import name' to mean 'from the same
741 package as this module is in. Imports without dots still default to the
742 old relative-then-absolute, unless 'from __future__ import
743 absolute_import' is used.
744
Brett Cannona7446e32006-02-27 23:39:10 +0000745- Properly check if 'warnings' raises an exception (usually when a filter set
746 to "error" is triggered) when raising a warning for raising string
747 exceptions.
748
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000749- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000750 The name was removed from Include/code.h.
751
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000752- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000753
Guido van Rossum1968ad32006-02-25 22:38:04 +0000754- Patch 1433928:
755 - The copy module now "copies" function objects (as atomic objects).
756 - dict.__getitem__ now looks for a __missing__ hook before raising
757 KeyError.
758
Tim Peters84ef21c2006-02-28 20:39:06 +0000759- PEP 343: with statement implemented. Needs ``from __future__ import
760 with_statement``. Use of 'with' as a variable will generate a warning.
761 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000762 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000763 The following objects have __context__ methods:
764 - The built-in file type.
765 - The thread.LockType type.
766 - The following types defined by the threading module:
767 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
768 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000769
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000770- Fix the encodings package codec search function to only search
771 inside its own package. Fixes problem reported in patch #1433198.
772
773 Note: Codec packages should implement and register their own
774 codec search function. PEP 100 has the details.
775
Tim Peters9ea89d22006-06-04 03:26:02 +0000776- PEP 353: Using ``Py_ssize_t`` as the index type.
777
778- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
779 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
780 now allow Python to make use of memory blocks exceeding 2**32 bytes for
781 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
782 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000783
Neal Norwitzfc76d632006-01-10 06:03:13 +0000784- Patch #1400181, fix unicode string formatting to not use the locale.
785 This is how string objects work. u'%f' could use , instead of .
786 for the decimal point. Now both strings and unicode always use periods.
787
Neal Norwitz671b9e32006-01-09 07:07:12 +0000788- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
789 configure would break checking curses.h.
790
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000791- Bug #959576: The pwd module is now builtin. This allows Python to be
792 built on UNIX platforms without $HOME set.
793
Neal Norwitzc10978f2005-12-19 06:07:16 +0000794- Bug #1072182, fix some potential problems if characters are signed.
795
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000796- Bug #889500, fix line number on SyntaxWarning for global declarations.
797
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000798- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
799
Neal Norwitze7214a12005-12-18 05:03:17 +0000800- Support for converting hex strings to floats no longer works.
801 This was not portable. float('0x3') now raises a ValueError.
802
Barry Warsaw2a38a862005-12-18 01:27:35 +0000803- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000804 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000805 is now displayed in interactive prompt banner.
806
Georg Brandlfa166682005-12-17 21:45:17 +0000807- Implementation of PEP 341 - Unification of try/except and try/finally.
808 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000809 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000810
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000811- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
812 now encodes backslash correctly.
813
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000814- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
815
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000816- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000817 and long longs.
818
Neal Norwitz67715f02005-11-09 06:59:35 +0000819- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000820 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000821 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000822
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000823- Replaced most Unicode charmap codecs with new ones using the
824 new Unicode translate string feature in the builtin charmap
825 codec; the codecs were created from the mapping tables available
826 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
827 encodings now include a mapping for the Apple logo)
828
Tim Peterse3547fd2005-12-16 23:13:57 +0000829- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000830
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000831- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000832
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000833- A new AST parser implementation was completed. The abstract
834 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000835 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000836
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000837- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000838 The following code now raises a SyntaxError: foo(a = i for i in range(10))
839
Neal Norwitz708e51a2005-10-03 04:48:15 +0000840- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
841
Neal Norwitz11bd1192005-10-03 00:54:56 +0000842- SF Bug #887946: fix segfault when redirecting stdin from a directory.
843 Provide a warning when a directory is passed on the command line.
844
Neal Norwitz40d37812005-10-02 01:48:49 +0000845- Fix segfault with invalid coding.
846
847- SF bug #772896: unknown encoding results in MemoryError.
848
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000849- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000850 supported a __len__() method which evaluated to False when the iterator
851 was empty.
852
Guido van Rossum630db602005-09-20 18:49:54 +0000853- On 64-bit platforms, when __len__() returns a value that cannot be
854 represented as a C int, raise OverflowError.
855
Skip Montanarof8948ca2005-09-19 03:54:46 +0000856- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000857 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000858
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000859- SF bug #893549: parsing keyword arguments was broken with a few format
860 codes.
861
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000862- Changes donated by Elemental Security to make it work on AIX 5.3
863 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
864 bug #105470: test_pwd fails on 64bit system (Opteron).
865
Guido van Rossum539c6622005-09-14 17:49:54 +0000866- Changes donated by Elemental Security to make it work on HP-UX 11 on
867 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
868
Georg Brandl4550b8d2005-08-26 06:43:52 +0000869- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000870 (fixes bug #1119418).
871
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000872- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
873
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000874- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
875 exceptions that cause a function to exit.
876
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000877- The implementation of set() and frozenset() was revised to use its
878 own internal data structure. Memory consumption is reduced by 1/3
879 and there are modest speed-ups as well. The API is unchanged.
880
Tim Petersde7990b2005-07-17 23:45:23 +0000881- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
882
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000883- SF bug #1229429: PyObject_CallMethod failed to decrement some
884 reference counts in some error exit cases.
885
Tim Petersecc6e6a2005-07-10 22:30:55 +0000886- SF bug #1185883: Python's small-object memory allocator took over
887 a block managed by the platform C library whenever a realloc specified
888 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000889 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000890 portable way to copy data from the C-managed block into Python's
891 small-object space without risking a memory fault. Python's small-object
892 realloc now leaves such blocks under the control of the platform C
893 realloc.
894
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000895- SF bug #1232517: An overflow error was not detected properly when
896 attempting to convert a large float to an int in os.utime().
897
Raymond Hettinger3296e692005-06-29 23:29:56 +0000898- SF bug #1224347: hex longs now print with lowercase letters just
899 like their int counterparts.
900
Michael W. Hudson188d4362005-06-20 16:52:57 +0000901- SF bug #1163563: the original fix for bug #1010677 ("thread Module
902 Breaks PyGILState_Ensure()") broke badly in the case of multiple
903 interpreter states; back out that fix and do a better job (see
904 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
905 for a longer write-up of the problem).
906
Michael W. Hudsondf888462005-06-03 14:41:55 +0000907- SF patch #1180995: marshal now uses a binary format by default when
908 serializing floats.
909
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000910- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
911 the routines that promise to produce IEEE 754 binary representations
912 of floats now simply copy bytes around.
913
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000914- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
915 278.

Brett Cannonc3647ac2005-04-26 03:45:26 +0000917- patch #1109424: int, long, float, complex, and unicode now check for the
918 proper magic slot for type conversions when subclassed. Previously the
919 magic slot was ignored during conversion. Semantics now match the way
920 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000921 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000922 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000923 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000924
Barry Warsawc8d907c2005-04-19 23:43:40 +0000925- Descriptors defined in C with a PyGetSetDef structure, where the setter is
926 NULL, now raise an AttributeError when attempting to set or delete the
927 attribute. Previously a TypeError was raised, but this was inconsistent
928 with the equivalent pure-Python implementation.
929
Michael W. Hudson774479c2005-04-18 08:46:17 +0000930- It is now safe to call PyGILState_Release() before
931 PyEval_InitThreads() (note that if there is reason to believe there
932 are multiple threads around you still must call PyEval_InitThreads()
933 before using the Python API; this fix is for extension modules that
934 have no way of knowing if Python is multi-threaded yet).
935
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000936- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
937 disabled caused a crash.
938
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000939- Bug #1165306: instancemethod_new allowed the creation of a method
940 with im_class == im_self == NULL, which caused a crash when called.
941
Tim Petersecc6e6a2005-07-10 22:30:55 +0000942- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000943 fixes the crash seen in bug #1165761
944
Raymond Hettinger96229b12005-03-11 06:49:40 +0000945- Added two new builtins, any() and all().
946
Brett Cannon409d8f22005-03-05 06:47:57 +0000947- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000948 (e.g., ``class C(): pass`` is no longer a syntax error).
949 Patch #1176012 added support to the 'parser' module and 'compiler' package
950 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000951
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000952- Patch #1115086: Support PY_LONGLONG in structmember.
953
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000954- Bug #1155938: new style classes did not check that __init__() was
955 returning None.
956
Tim Petersecc6e6a2005-07-10 22:30:55 +0000957- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000958 ('\') with a specific error message.
959
Martin v. Löwisff232d72005-03-03 09:24:38 +0000960- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
961
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000962- Bug #1124295: the __name__ attribute of file objects was
963 inadvertently made inaccessible in restricted mode.
964
Tim Petersecc6e6a2005-07-10 22:30:55 +0000965- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000966 an ferror() call.
967
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000968- min() and max() now support key= arguments with the same meaning as in
969 list.sort().
970
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000971- The peephole optimizer now performs simple constant folding in expressions:
972 (2+3) --> (5).
973
Raymond Hettingera422c342005-01-11 03:03:27 +0000974- set and frozenset objects can now be marshalled. SF #1098985.
975
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000976- Bug #1077106: Poor argument checking could cause memory corruption
977 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000978
Jeremy Hyltonab630502005-02-04 18:44:06 +0000979- The parser did not complain about future statements in illegal
980 positions. It once again reports a syntax error if a future
981 statement occurs after anything other than a doc string.
982
Neil Schemenauercf52c072005-08-12 17:34:58 +0000983- Change the %s format specifier for str objects so that it returns a
984 unicode instance if the argument is not an instance of basestring and
985 calling __str__ on the argument returns a unicode instance.
986
Tim Petersf4e69282006-02-27 17:15:31 +0000987- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
988 current thread state when the auto-GIL-state machinery knows about
989 it (since the thread state is being deleted, continuing to remember it
990 can't help, but can hurt if another thread happens to get created with
991 the same thread id).

1022
Neal Norwitzb62c4332006-03-04 18:35:47 +00001023- The timing module is no longer built by default. It was deprecated

Anthony Baxter93f5b932006-04-03 08:05:07 +00001187- The email module's parsedate_tz function now sets the daylight savings
1188 flag to -1 (unknown) since it can't tell from the date whether it should
1189 be set.
1190

1192 now sport attributes that provide access to the parts of the result.
1193
Georg Brandl7f6b67c2006-04-01 08:35:18 +00001194- Patch #1462498: sgmllib now handles entity and character references
1195 in attribute values.
1196
Anthony Baxterc51ee692006-04-01 00:57:31 +00001197- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001198 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001199 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001200 module will not be built.
1201
Tim Petersc17976e2006-04-01 00:26:53 +00001202- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1203 aren't officially supported here, and trying to use them will probably
1204 raise an exception some day. But dicts have been allowed, and "mostly
1205 worked", so support for them won't go away without warning.
1206
Georg Brandl338ef7d2006-03-31 18:42:16 +00001207- Bug #1445068: getpass.getpass() can now be given an explicit stream
1208 argument to specify where to write the prompt.
1209

1216 key to be used for signing the uploaded code.
1217
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001218- Queue.Queue objects now support .task_done() and .join() methods
1219 to make it easier to monitor when daemon threads have completed
1220 processing all enqueued tasks. Patch #1455676.
1221
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001222- popen2.Popen objects now preserve the command in a .cmd attribute.
1223
Thomas Hellerc61c0492006-03-22 10:09:27 +00001224- Added the ctypes ffi package.
1225
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001226- email 4.0 package now integrated. This is largely the same as the email 3.0
1227 package that was included in Python 2.3, except that PEP 8 module names are
1228 now used (e.g. mail.message instead of email.Message). The MIME classes
1229 have been moved to a subpackage (e.g. email.mime.text instead of
1230 email.MIMEText). The old names are still supported for now. Several
1231 deprecated Message methods have been removed and lots of bugs have been
1232 fixed. More details can be found in the email package documentation.
1233
Walter Dörwald40108c92006-03-27 08:15:44 +00001234- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1235 (a subclass of tuple) that provides incremental decoders and encoders
1236 (a way to use stateful codecs without the stream API). Python functions
1237 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1238 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1239 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001240
Walter Dörwald067db482006-03-15 22:17:27 +00001241- Patch #1359365: Calling next() on a closed StringIO.String object raises
1242 a ValueError instead of a StopIteration now (like file and cString.String do).
1243 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1244 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001245
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001246- A regrtest option -w was added to re-run failed tests in verbose mode.

1249 interpreter to exit.
1250
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001251- The function get_count() has been added to the gc module, and gc.collect()
1252 grew an optional 'generation' argument.
1253
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001254- A library msilib to generate Windows Installer files, and a distutils

1258 and helpful context managers nested() and closing().
1259

1314 LoadError as documented, instead of IOError. For compatibility,
1315 LoadError subclasses IOError.
1316

Tim Peterse3547fd2005-12-16 23:13:57 +00001318 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1319 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1320 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1321 Ronald L. Rivest offered this advice for Python:
1322
1323 "The consensus of researchers in this area (at least as
1324 expressed at the NIST Hash Function Workshop 10/31/05),
1325 is that SHA-256 is a good choice for the time being, but
1326 that research should continue, and other alternatives may
1327 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001328
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001329- Added a subset of Fredrik Lundh's ElementTree package. Available

Walter Dörwalda05834e2005-10-09 19:38:21 +00001383 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001384

1400 parameter, but uses the usual "kwargs=None".
1401
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001402- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1422 Bug #1224621.
1423
Raymond Hettinger68c04532005-06-10 11:05:19 +00001424- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001425 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001426 the generate_tokens() function now accepts a callable argument that
1427 terminates by raising StopIteration.

1437 class at all.
1438
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001439- distutils.commands.upload was added to support uploading distribution

Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001450- Bug #1163325: Decimal infinities failed to hash. Attempting to
1451 hash a NaN raised an InvalidOperation instead of a TypeError.
1452
Tim Petersecc6e6a2005-07-10 22:30:55 +00001453- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001454 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1455

Martin v. Löwisa4dac402005-03-03 11:39:45 +00001465 profile.py if available.
1466
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001467- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1468

1483
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001484- Patch #1049151: xdrlib now unpacks booleans as True or False.
1485
Raymond Hettingerbab41432005-02-05 01:31:19 +00001486- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1487
Guido van Rossumd0641422005-02-03 15:01:24 +00001488- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1489 disables recursive traversal through instance attributes, which can
1490 be exploited in various ways.
1491
Tim Peterse3547fd2005-12-16 23:13:57 +00001492- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001493 flags on the HTTP listening socket.
1494
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001495- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1496 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1497
Tim Peterse3547fd2005-12-16 23:13:57 +00001498- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001499 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1500
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001501- Bug #1110478: Revert os.environ.update to do putenv again.
1502
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001503- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1504
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001505- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1506
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001507- Enhancements to the csv module:
1508
1509 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001510 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001511 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001512 + Dialect parameter parsing has been re-implemented to improve error
1513 reporting.
1514 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1515 dictates.
1516 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001517 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001518 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001519 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1520 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001521 + reader now allows \r characters to be quoted (previously it only allowed
1522 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001523 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001524 + Dialect classes passed to the module are no longer instantiated by
1525 the module before being parsed (the former validation scheme required
1526 this, but the mechanism was unreliable).
1527 + The dialect registry now contains instances of the internal
1528 C-coded dialect type, rather than references to python objects.
1529 + the internal c-coded dialect type is now immutable.
1530 + register_dialect now accepts the same keyword dialect specifications
1531 as the reader and writer, allowing the user to register dialects
1532 without first creating a dialect class.
1533 + a configurable limit to the size of parsed fields has been added -
1534 previously, an unmatched quote character could result in the entire
1535 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001536 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001537 the parser field size limit (returning the former limit). The initial
1538 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001539 + A line_num attribute has been added to the reader object, which tracks
1540 the number of lines read from the source iterator. This is not
1541 the same as the number of records returned, as records can span
1542 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001543 + reader and writer objects were not being registered with the cyclic-GC.
1544 This has been fixed.
1545
Brett Cannone6539c42005-01-08 02:43:53 +00001546- _DummyThread objects in the threading module now delete self.__block that is
1547 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1548 lock primitives tend to be limited in number and thus should not be wasted on
1549 a _DummyThread object. Fixes bug #1089632.
1550
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001551- The imghdr module now detects Exif files.
1552
Raymond Hettinger6065d322004-12-20 23:51:53 +00001553- StringIO.truncate() now correctly adjusts the size attribute.
1554 (Bug #951915).
1555
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001556- locale.py now uses an updated locale alias table (built using
1557 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1558 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001559 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001560
Raymond Hettinger3557f422004-12-07 12:02:02 +00001561- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1562
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001563- the pickle module no longer accepts the deprecated None option in the
1564 args tuple returned by __reduce__().
1565
Brett Cannon84667c02004-12-07 03:25:18 +00001566- optparse now optionally imports gettext. This allows its use in setup.py.
1567
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001568- the pickle module no longer uses the deprecated bin parameter.
1569
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001570- the shelve module no longer uses the deprecated binary parameter.
1571
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001572- the pstats module no longer uses the deprecated ignore() method.
1573
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001574- the filecmp module no longer uses the deprecated use_statcache argument.
1575
Raymond Hettinger664347b2004-12-04 21:21:53 +00001576- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1577 extended or overridden by subclasses. Formerly, the subclassed method would
1578 be ignored by the rest of the module. (Bug #1078905).
1579
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001580- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001581 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001582
Walter Dörwald36733692004-12-22 12:50:50 +00001583- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1584 once when a size argument is given. This prevents a buffer overflow in the
1585 tokenizer with very long source lines.
1586
Barry Warsaw538561e2006-01-01 21:48:54 +00001587- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1588 immediately after creating the object, without any intervening
1589 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001590
Skip Montanaro05885812005-01-16 20:48:27 +00001591- The reconvert.quote function can now emit triple-quoted strings. The
1592 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001593
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001594- ``UserString.MutableString`` now supports negative indices in
1595 ``__setitem__`` and ``__delitem__``
1596
Greg Ward40407942005-03-05 02:53:17 +00001597- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1598 correctly.
1599
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001600- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1601 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1602 character even if the user has passed a size parameter to get a proper
1603 line ending. Remove the special handling of a "\r\n" that has been split
1604 between two lines.
1605
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001606- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1607 about illegal code points. The codec now supports PEP 293 style error
1608 handlers.
1609
Walter Dörwald78a78b02005-09-01 12:04:29 +00001610- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001611 from the input stream, so that the output is a byte string in the correct
1612 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001613
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001614- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1615 considering it exactly like a '*'.
1616
Walter Dörwald007f8df2005-10-09 19:42:27 +00001617- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1618 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001619
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001620- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1621
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001622- Patch #1413711: Certain patterns of differences were making difflib
1623 touch the recursion limit.
1624
Walter Dörwald58917a62006-03-31 15:26:22 +00001625- Bug #947906: An object oriented interface has been added to the calendar
1626 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001627 called as a script (e.g. via ``python -mcalendar``). Localized month and
1628 weekday names can be ouput (even if an exotic encoding is used) using
1629 special classes that use unicode.

1632-----
1633
Neal Norwitz602d3392006-03-31 08:21:40 +00001634- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1635 by using -mieee gcc option.
1636
Martin v. Löwis86d66262006-02-17 08:40:11 +00001637- Patch #1432345: Make python compile on DragonFly.
1638
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001639- Build support for Win64-AMD64 was added.
1640
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001641- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1642
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001643- Patch #881820: look for openpty and forkpty also in libbsd.
1644
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001645- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1646 The zlib module is now builtin on Windows.
1647
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001648- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1649
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001650- Bug #1189330: configure did not correctly determine the necessary
1651 value of LINKCC if python was built with GCC 4.0.
1652
Trent Mick8321b422005-07-26 02:29:21 +00001653- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1654 vulnerability in zlib 1.2.1 and 1.2.2.
1655
Brett Cannon08cd5982005-04-24 22:26:38 +00001656- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1657 flags that change binary compatibility. Changes were also made to
1658 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001659 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001660
Bob Ippolitoed233462005-03-29 13:47:59 +00001661- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1662 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1663 no longer exists). This configure patch makes things right.
1664
Martin v. Löwise2713be2005-03-08 15:03:08 +00001665- Bug #1158607: Build with --disable-unicode again.
1666
Brett Cannon46d96232005-02-16 00:07:19 +00001667- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1668 defined. Discovered as a result of not being able to build on OS X.
1669
Brett Cannon516592f2004-12-07 00:42:59 +00001670- setup.py now uses the directories specified in LDFLAGS using the -L option
1671 and in CPPFLAGS using the -I option for adding library and include
1672 directories, respectively, for compiling extension modules against. This has
1673 led to the core being compiled using the values in CPPFLAGS. It also removes
1674 the need for the special-casing of both DarwinPorts and Fink for darwin since
1675 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1676 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1677 Fink, ``-I/opt/local/include`` for DarwinPorts).
1678
Brett Cannon43802422005-02-10 20:48:03 +00001679- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1680 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1681 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1682 Closes bug #1096244. Thanks Gregory Bond.

1685-----
1686
Tim Petersc9d78aa2006-03-26 23:27:58 +00001687- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1688 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1689 is obtained via the ``PyObject_`` family, it must be released via the
1690 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1691 always been officially true, but when Python's small-object allocator was
1692 introduced, an attempt was made to cater to a few extension modules
1693 discovered at the time that obtained memory via ``PyObject_New`` but
1694 released it via ``PyMem_DEL``. It's years later, and if such code still
1695 exists it will fail now (probably with segfaults, but calling wrong
1696 low-level memory management functions can yield many symptoms).
1697
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001698- Added a C API for set and frozenset objects.
1699
Raymond Hettinger66517482004-12-03 11:45:13 +00001700- Removed PyRange_New().

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001702- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1703 mapping argument now. This string is used as a mapping table. Byte values
1704 greater than the length of the string and 0xFFFE are treated as undefined
1705 mappings.
