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.

35
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000036- Bug #1441486: The literal representation of -(sys.maxint - 1)
37 again evaluates to a int object, not a long.
38
Neil Schemenauer0e07b602006-07-09 16:16:34 +000039- Bug #1501934: The scope of global variables that are locally assigned
40 using augmented assignment is now correctly determined.
41
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000042- Bug #927248: Recursive method-wrapper objects can now safely
43 be released.
44
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000045- Bug #1417699: Reject locale-specific decimal point in float()
46 and atof().
47
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000048- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
49 omit a default "error" argument for NULL pointer. This allows
50 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000051
Neal Norwitzfb48afa2006-07-08 05:31:37 +000052- Bug #1519018: 'as' is now validated properly in import statements.
53
Neal Norwitz28746ab2006-07-09 22:14:42 +000054- On 64 bit systems, int literals that use less than 64 bits are
55 now ints rather than longs.
56
Neal Norwitzed657552006-07-10 00:04:44 +000057- Bug #1512814, Fix incorrect lineno's when code at module scope
58 started after line 256.
59
Tim Peters32a83612006-07-10 21:08:24 +000060- New function ``sys._current_frames()`` returns a dict mapping thread
61 id to topmost thread stack frame. This is for expert use, and is
62 especially useful for debugging application deadlocks. The functionality
63 was previously available in Fazal Majid's ``threadframe`` extension
64 module, but it wasn't possible to do this in a wholly threadsafe way from
65 an extension.

Martin v. Löwis06c68b82006-07-10 22:11:28 +000070- Patch #1519566: Update turtle demo, make begin_fill idempotent.
71
Tim Peters32a83612006-07-10 21:08:24 +000072- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +000073 environment variable to be set in order to the SDK environment
74 for finding the compiler, include files, etc.
75
Martin v. Löwis388a8c22006-07-06 19:28:03 +000076- Bug #1515998: Properly generate logical ids for files in bdist_msi.
77
Nick Coghlan2d792252006-07-06 13:47:18 +000078- warnings.py now ignores ImportWarning by default
79
Thomas Woutersadd19112006-07-05 11:03:49 +000080- string.Template() now correctly handles tuple-values. Previously,
81 multi-value tuples would raise an exception and single-value tuples would
82 be treated as the value they contain, instead.
83
Martin v. Löwisede77f52006-07-03 13:01:35 +000084- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
85 even if some data are received.
86
Martin v. Löwis45482392006-07-03 12:28:58 +000087- Bug #1267547: Put proper recursive setup.py call into the

Martin v. Löwis2b88f632006-07-03 10:19:49 +000094 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +000095
Martin v. Löwisbd39c032006-07-03 09:44:00 +000096- Bug #1514703: Only setup canvas window in turtle when the canvas
97 is created.
98
Martin v. Löwis7596e832006-07-01 15:33:37 +000099- Bug #1513223: .close() of a _socketobj now releases the underlying
100 socket again, which then gets closed as it becomes unreferenced.
101
Fred Drake10497c82006-06-29 02:57:48 +0000102- Bug #1504333: Make sgmllib support angle brackets in quoted
103 attribute values.
104
105- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
106 sgmllib ('[' and ']' were not accepted).
107
Georg Brandl1be63af2006-06-28 20:23:25 +0000108- Fix a bug in the turtle module's end_fill function.
109
Brett Cannon53ab5b72006-06-22 16:49:14 +0000110- Bug #1510580: The 'warnings' module improperly required that a Warning
111 category be either a types.ClassType and a subclass of Warning. The proper
112 check is just that it is a subclass with Warning as the documentation states.
113
Georg Brandlad29e632006-06-21 17:45:17 +0000114- The compiler module now correctly compiles the new try-except-finally
115 statement (bug #1509132).
116
Neal Norwitz60373cd2006-06-22 06:30:50 +0000117- The wsgiref package is now installed properly on Unix.
118
Vinay Sajip28e57612006-07-01 10:45:20 +0000119- A bug was fixed in logging.config.fileConfig() which caused a crash on
120 shutdown when fileConfig() was called multiple times.
121
Gerhard Häring762fbd32006-07-02 17:48:30 +0000122- The sqlite3 module did cut off data from the SQLite database at the first
123 null character before sending it to a custom converter. This has been fixed
124 now.
125
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000126Extension Modules
127-----------------
128
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000129- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
130 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
131 The patch makes sockets use poll() internally where available.
132
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000133- Assigning None to pointer type fields in ctypes structures possible
134 overwrote the wrong fields, this is fixed now.
135
136- Fixed a segfault in _ctypes when ctypes.wintypes were imported
137 on non-Windows platforms.
138
139- Bug #1518190: The ctypes.c_void_p constructor now accepts any
140 integer or long, without range checking.
141
142- Patch #1517790: It is now possible to use custom objects in the ctypes
143 foreign function argtypes sequence as long as they provide a from_param
144 method, no longer is it required that the object is a ctypes type.
145
146- The '_ctypes' extension module now works when Python is configured
147 with the --without-threads option.
148
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000149- Bug #1513646: os.access on Windows now correctly determines write
150 access, again.
151
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000152- Bug #1512695: cPickle.loads could crash if it was interrupted with
153 a KeyboardInterrupt.
154
Neal Norwitza12aa882006-07-06 06:45:08 +0000155- Bug #1296433: parsing XML with a non-default encoding and
156 a CharacterDataHandler could crash the interpreter in pyexpat.
157
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000158- Patch #1516912: improve Modules support for OpenVMS.
159

161-----
162
Tim Peters32a83612006-07-10 21:08:24 +0000163- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000164 Previously, the slight difference could cause compilation errors of the
165 'zlib' module on systems with more than one version of zlib.
166
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000167- The MSI compileall step was fixed to also support a TARGETDIR
168 with spaces in it.
169
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000170- Bug #1517388: sqlite3.dll is now installed on Windows independent
171 of Tcl/Tk.
172
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000173- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000174 trying to be installed even though it's empty.

178
179- Call os.waitpid() at the end of tests that spawn child processes in order
180 to minimize resources (zombies).
181
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000182Documentation
183-------------
184
Nick Coghlan2d792252006-07-06 13:47:18 +0000185- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
186 documentation for the warnings module.
187
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000188- Patch #1509163: MS Toolkit Compiler no longer available.
189
Neal Norwitz56640df2006-07-10 02:36:41 +0000190- Patch #1504046: Add documentation for xml.etree.

197Core and builtins
198-----------------
199
Georg Brandla56b9152006-06-19 06:35:54 +0000200- Patch #1507676: Error messages returned by invalid abstract object operations
201 (such as iterating over an integer) have been improved and now include the
202 type of the offending object to help with debugging.
203
Brett Cannonea3912b2006-06-13 21:46:41 +0000204- Bug #992017: A classic class that defined a __coerce__() method that returned
205 its arguments swapped would infinitely recurse and segfault the interpreter.
206
Neal Norwitz909eb122006-06-12 02:13:21 +0000207- Fix the socket tests so they can be run concurrently.
208
Neal Norwitzb9845e72006-06-12 02:11:18 +0000209- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000210 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000211
Brett Cannon22565aa2006-06-09 22:31:23 +0000212- Bug #532646: object.__call__() will continue looking for the __call__
213 attribute on objects until one without one is found. This leads to recursion
214 when you take a class and set its __call__ attribute to an instance of the
215 class. Originally fixed for classic classes, but this fix is for new-style.
216 Removes the infinite_rec_3 crasher.
217
Georg Brandl24250812006-06-09 18:45:48 +0000218- The string and unicode methods startswith() and endswith() now accept
219 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
220
Brett Cannonde3b0522006-06-08 17:00:45 +0000221- Buffer objects, at the C level, never used the char buffer
222 implementation even when the char buffer for the wrapped object was
223 explicitly requested (originally returned the read or write buffer).
224 Now a TypeError is raised if the char buffer is not present but is
225 requested.
226
Georg Brandlddbaa662006-06-04 21:56:52 +0000227- Patch #1346214: Statements like "if 0: suite" are now again optimized
228 away like they were in Python 2.4.
229
Georg Brandlb7c8f542006-05-27 12:30:25 +0000230- Builtin exceptions are now full-blown new-style classes instead of
231 instances pretending to be classes, which speeds up exception handling
232 by about 80% in comparison to 2.5a2.
233
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000234- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
235 Unicode 4.1.
236
Georg Brandlf4ef1162006-05-26 18:03:31 +0000237- Patch #921466: sys.path_importer_cache is now used to cache valid and
238 invalid file paths for the built-in import machinery which leads to
239 fewer open calls on startup.
240
Tim Peters696cf432006-05-24 21:10:40 +0000241- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
242 of-2 bases. The largest speedup is for inputs with about 1000 decimal
243 digits. Conversion from non-power-of-2 bases remains quadratic-time in
244 the number of input digits (it was and remains linear-time for bases
245 2, 4, 8, 16 and 32).
246
Tim Petersb713ec22006-05-23 18:45:30 +0000247- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
248 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
249 an integer close to ``sys.maxint``. This was repaired by patch
250 #1335972, which also gives a nice speedup.
251
Richard Jonescebbefc2006-05-23 18:28:17 +0000252- Patch #1337051: reduced size of frame objects.
253
254- PyErr_NewException now accepts a tuple of base classes as its
255 "base" parameter.
256
Richard Jones7c88dcc2006-05-23 10:37:38 +0000257- Patch #876206: function call speedup by retaining allocated frame
258 objects.
259
Georg Brandl7b90e162006-05-18 07:01:27 +0000260- Bug #1462152: file() now checks more thoroughly for invalid mode
261 strings and removes a possible "U" before passing the mode to the
262 C library function.
263
Neal Norwitz1004a532006-05-15 07:17:23 +0000264- Patch #1488312, Fix memory alignment problem on SPARC in unicode
265
Neal Norwitz373f0a72006-05-15 07:04:36 +0000266- Bug #1487966: Fix SystemError with conditional expression in assignment
267
Martin v. Löwis879768d2006-05-11 13:28:43 +0000268- WindowsError now has two error code attributes: errno, which carries
269 the error values from errno.h, and winerror, which carries the error
270 values from winerror.h. Previous versions put the winerror.h values
271 (from GetLastError()) into the errno attribute.
272
Martin v. Löwis77736712006-05-04 05:51:03 +0000273- Patch #1475845: Raise IndentationError for unexpected indent.
274
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000275- Patch #1479181: split open() and file() from being aliases for each other.
276
Tim Peters44bd9862006-06-01 13:49:23 +0000277- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
278 methods were always silently ignored by dictionaries when comparing keys.
279 They are now passed through (except when using the C API function
280 ``PyDict_GetItem()``, whose semantics did not change).
281
282- Bug #1456209: In some obscure cases it was possible for a class with a
283 custom ``__eq__()`` method to confuse dict internals when class instances
284 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
285 No, you don't have any code that did this ;-)

292- Patch #1462338: Upgrade pyexpat to expat 2.0.0
293
Brett Cannon6ee7d012006-06-08 16:23:04 +0000294- Change binascii.hexlify to accept a read-only buffer instead of only a char
295 buffer and actually follow its documentation.
296
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000297- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
298
Nick Coghlanc649ec52006-05-29 12:43:05 +0000299- Patch #1478788 (modified version): The functional extension module has
300 been renamed to _functools and a functools Python wrapper module added.
301 This provides a home for additional function related utilities that are
302 not specifically about functional programming. See PEP 309.
303
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000304- Patch #1493701: performance enhancements for struct module.

307
Georg Brandl8d3342b2006-05-16 07:38:27 +0000308- Patch #1435422: zlib's compress and decompress objects now have a
309 copy() method.
310
Andrew MacIntyre92913322006-06-13 15:04:24 +0000311- Patch #1454481: thread stack size is now tunable at runtime for thread
312 enabled builds on Windows and systems with Posix threads support.
313
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000314- On Win32, os.listdir now supports arbitrarily-long Unicode path names
315 (up to the system limit of 32K characters).
316
317- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
318 As a result, these functions now raise WindowsError instead of OSError.
319
Tim Peters7a822da2006-05-25 21:50:17 +0000320- ``time.clock()`` on Win64 should use the high-performance Windows
321 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000324- Calling Tk_Init twice is refused if the first call failed as that
325 may deadlock.
326
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000327- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
328 accept it without potentially using an uninitialized pointer.
329
330- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
331 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smithf0547d02006-06-05 17:38:04 +0000335 [pybsddb project SF patch number 1466734]
336
Gregory P. Smith372b5832006-06-05 18:48:21 +0000337- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
338 parameter is supplied. [SF pybsddb bug #1477863]
339
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000340- bsddb: the __len__ method of a DB object has been fixed to return correct
341 results. It could previously incorrectly return 0 in some cases.
342 Fixes SF bug 1493322 (pybsddb bug 1184012).
343
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000344- bsddb: the bsddb.dbtables Modify method now raises the proper error and
345 aborts the db transaction safely when a modifier callback fails.
346 Fixes SF python patch/bug #1408584.
347
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000348- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000349 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000350 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
351 database calls that would previously deadlock. [SF python bug #775414]

381 double-byte encodings.
382
Tim Peters43898b42006-06-14 04:09:25 +0000383- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
384 guarantee that adjacent triples in the return list always describe
385 non-adjacent blocks. Previously, a pair of matching blocks could end
386 up being described by multiple adjacent triples that formed a partition
387 of the matching pair.

396
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000397- The wsgiref package has been added to the standard library.
398
Nick Coghlan676725d2006-06-08 13:54:49 +0000399- The functions update_wrapper() and wraps() have been added to the functools
400 module. These make it easier to copy relevant metadata from the original
401 function when writing wrapper functions.
402
Tim Petersd6a9eef2006-06-05 01:48:21 +0000403- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
404 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000405
Martin v. Löwis3f767792006-06-04 19:36:28 +0000406- Patch #1359618: Speed up charmap encoder by using a trie structure
407 for lookup.
408
Tim Petersd609b1a2006-06-02 23:22:51 +0000409- The functions in the ``pprint`` module now sort dictionaries by key
410 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
411 if and only if its display required more than one line, although that
412 wasn't documented. The new behavior increases predictability; e.g.,
413 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
414
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000415- Patch #1497027: try HTTP digest auth before basic auth in urllib2

426 format_string() to get the effect of "format % items" but locale-aware,
427 and currency() to format a monetary number with currency sign.
428

436 stdout arguments, making it possible to redirect input and output
437 for remote debugging.
438
439- Patch #1484695: Update the tarfile module to version 0.8. This fixes
440 a couple of issues, notably handling of long file names using the
441 GNU LONGNAME extension.

488*Release date: 27-APR-2006*
489
490Core and builtins
491-----------------
492
Thomas Heller1b046642006-04-18 18:51:06 +0000493- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
494 by converting these apis from macros into exported functions again:
495
496 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
497 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
498 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
499 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
500 PyRun_String Py_CompileString
501
Martin v. Löwis45294a92006-04-18 06:24:08 +0000502- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
503
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000504- All uses of PyStructSequence_InitType have been changed to initialize
505 the type objects only once, even if the interpreter is initialized
506 multiple times.
507
Neal Norwitz61546162006-04-14 05:20:28 +0000508- Bug #1454485, array.array('u') could crash the interpreter. This was
509 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
510 to unicode when it didn't make sense. 'u#' now requires a unicode string.
511
512- Py_UNICODE is unsigned. It was always documented as unsigned, but
513 due to a bug had a signed value in previous versions.
514
Tim Peters3a5e8b12006-04-11 01:44:07 +0000515- Patch #837242: ``id()`` of any Python object always gives a positive
516 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
517 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000518 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000519 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000520
Tim Peters3a5e8b12006-04-11 01:44:07 +0000521 def __hash__(self):
522 return id(self) # WRONG
523
524 because a hash result must be a (short) Python int but it was always
525 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000526 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000527 was always usable as a hash value before this patch. That's no longer
528 necessarily so.
529
530- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000531 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000532 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000533 #1454844)
534
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000535- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
536 involving generators that have paused outside of any ``try`` or ``with``
537 blocks. (In 2.5a1, a paused generator that was part of a reference
538 cycle could not be garbage collected, regardless of whether it was
539 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +0000567- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
568 a doctest to be skipped (the code is not run, and the expected output
569 or exception is ignored).
570

575 hex, octal, or binary; add ``append_const`` action; keep going if
576 gettext cannot be imported; added ``OptionParser.destroy()`` method;
577 added ``epilog`` for better help generation).
578
Tim Peters21fbd572006-04-21 21:18:10 +0000579- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
580 called from a thread spawned as a side effect of importing a module.
581
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000582- The pydoc module now supports documenting packages contained in
583 .zip or .egg files.
584
585- The pkgutil module now has several new utility functions, such
586 as ``walk_packages()`` to support working with packages that are either
587 in the filesystem or zip files.
588
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000589- The mailbox module can now modify and delete messages from
590 mailboxes, in addition to simply reading them. Thanks to Gregory
591 K. Johnson for writing the code, and to the 2005 Google Summer of
592 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000593
Tim Petersc7605f22006-04-17 21:12:33 +0000594- The ``__del__`` method of class ``local`` in module ``_threading_local``
595 returned before accomplishing any of its intended cleanup.
596

604 Windows. Bug #1469163.
605
Phillip J. Eby47032112006-04-11 01:07:43 +0000606- The warnings, linecache, inspect, traceback, site, and doctest modules

Hye-Shik Changf4795c82006-04-26 19:20:26 +0000637- Fixed a libffi build problem on MIPS systems.
638
Tim Peters8931ff12006-05-13 23:28:20 +0000639- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
640 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
641 and "%zu" for unsigned integers of type ``size_t``.
642
Anthony Baxter51bcb682006-04-05 14:51:42 +0000643Tests
644-----
645
Nick Coghlanda2268f2006-04-24 04:37:15 +0000646- test_contextlib now checks contextlib.nested can cope with exceptions
647 being raised and caught inside exit handlers.
648
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000649- test_cmd_line now checks operation of the -m and -c command switches
650
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000651- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
652 it separately and by hand. It also wasn't cleaning up its changes to
653 the current Decimal context.
654
Thomas Woutersabd08882006-04-26 15:53:30 +0000655- regrtest.py now has a -M option to run tests that test the new limits of
656 containers, on 64-bit architectures. Running these tests is only sensible
657 on 64-bit machines with more than two gigabytes of memory. The argument
658 passed is the maximum amount of memory for the tests to use.

662
663- Added the Python benchmark suite pybench to the Tools/ directory;
664 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000666Documentation
667-------------
668
Tim Petersb06d28c2006-05-12 01:57:59 +0000669- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
670
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000671- PEP 343: Added Context Types section to the library reference
672 and attempted to bring other PEP 343 related documentation into
673 line with the implementation and/or python-dev discussions.
674
Tim Peters8dc73d22006-04-24 02:03:16 +0000675- Bug #1337990: clarified that ``doctest`` does not support examples
676 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000679What's New in Python 2.5 alpha 1?
680=================================
681
Anthony Baxterebed3f62006-04-03 15:03:44 +0000682*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000683
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000684Core and builtins
685-----------------
686
Nick Coghlan43832302006-04-23 17:04:07 +0000687- PEP 338: -m command line switch now delegates to runpy.run_module
688 allowing it to support modules in packages and zipfiles
689
Martin v. Löwisc661b882006-04-20 04:54:23 +0000690- On Windows, .DLL is not an accepted file name extension for
691 extension modules anymore; extensions are only found if they
692 end in .PYD.
693
Martin v. Löwisea62d252006-04-03 10:56:49 +0000694- Bug #1421664: sys.stderr.encoding is now set to the same value as
695 sys.stdout.encoding.
696
Neal Norwitz92e212f2006-04-03 04:48:37 +0000697- __import__ accepts keyword arguments.
698
Georg Brandlccadf842006-03-31 18:54:53 +0000699- Patch #1460496: round() now accepts keyword arguments.
700
Anthony Baxter262c00a2006-03-30 10:53:17 +0000701- Fixed bug #1459029 - unicode reprs were double-escaped.
702
Hye-Shik Changd478f342006-03-23 12:32:36 +0000703- Patch #1396919: The system scope threads are reenabled on FreeBSD
704 5.4 and later versions.
705
Neal Norwitze98ccf62006-03-23 05:39:47 +0000706- Bug #1115379: Compiling a Unicode string with an encoding declaration
707 now gives a SyntaxError.
708
Georg Brandlabd1ff82006-03-18 07:59:59 +0000709- Previously, Python code had no easy way to access the contents of a
710 cell object. Now, a ``cell_contents`` attribute has been added
711 (closes patch #1170323).
712
Tim Peterscf79aac2006-03-16 01:14:46 +0000713- Patch #1123430: Python's small-object allocator now returns an arena to
714 the system ``free()`` when all memory within an arena becomes unused
715 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
716 freed. Some applications will see a drop in virtual memory size now,
717 especially long-running applications that, from time to time, temporarily
718 use a large number of small objects. Note that when Python returns an
719 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000720 platform C library will in turn return that memory to the operating system.
721 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000722 appears to be effective at least on Microsoft C and gcc-based systems.
723 Thanks to Evan Jones for hard work and patience.
724
Georg Brandl533ff6f2006-03-08 18:09:27 +0000725- Patch #1434038: property() now uses the getter's docstring if there is
726 no "doc" argument given. This makes it possible to legitimately use
727 property() as a decorator to produce a read-only property.
728
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000729- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
730 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
731 of requiring an int or long in slicing and a few other contexts, enabling
732 other objects (e.g. Numeric Python's integers) to be used as slice indices.
733
Neal Norwitz995acdf2006-03-07 05:01:00 +0000734- Fixed various bugs reported by Coverity's Prevent tool.
735
Brett Cannonbf364092006-03-01 04:25:17 +0000736- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
737 new exception base class, BaseException, which has a new message attribute.
738 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
739 Raising a string exception now raises a DeprecationWarning.
740
Thomas Woutersfb609f42006-02-28 16:37:25 +0000741- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
742 explicitly relative, using 'from .module import name' to mean 'from the same
743 package as this module is in. Imports without dots still default to the
744 old relative-then-absolute, unless 'from __future__ import
745 absolute_import' is used.
746
Brett Cannona7446e32006-02-27 23:39:10 +0000747- Properly check if 'warnings' raises an exception (usually when a filter set
748 to "error" is triggered) when raising a warning for raising string
749 exceptions.
750
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000751- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000752 The name was removed from Include/code.h.
753
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000754- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000755
Guido van Rossum1968ad32006-02-25 22:38:04 +0000756- Patch 1433928:
757 - The copy module now "copies" function objects (as atomic objects).
758 - dict.__getitem__ now looks for a __missing__ hook before raising
759 KeyError.
760
Tim Peters84ef21c2006-02-28 20:39:06 +0000761- PEP 343: with statement implemented. Needs ``from __future__ import
762 with_statement``. Use of 'with' as a variable will generate a warning.
763 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000764 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000765 The following objects have __context__ methods:
766 - The built-in file type.
767 - The thread.LockType type.
768 - The following types defined by the threading module:
769 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
770 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000771
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000772- Fix the encodings package codec search function to only search
773 inside its own package. Fixes problem reported in patch #1433198.
774
775 Note: Codec packages should implement and register their own
776 codec search function. PEP 100 has the details.
777
Tim Peters9ea89d22006-06-04 03:26:02 +0000778- PEP 353: Using ``Py_ssize_t`` as the index type.
779
780- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
781 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
782 now allow Python to make use of memory blocks exceeding 2**32 bytes for
783 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
784 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000785
Neal Norwitzfc76d632006-01-10 06:03:13 +0000786- Patch #1400181, fix unicode string formatting to not use the locale.
787 This is how string objects work. u'%f' could use , instead of .
788 for the decimal point. Now both strings and unicode always use periods.
789
Neal Norwitz671b9e32006-01-09 07:07:12 +0000790- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
791 configure would break checking curses.h.
792
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000793- Bug #959576: The pwd module is now builtin. This allows Python to be
794 built on UNIX platforms without $HOME set.
795
Neal Norwitzc10978f2005-12-19 06:07:16 +0000796- Bug #1072182, fix some potential problems if characters are signed.
797
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000798- Bug #889500, fix line number on SyntaxWarning for global declarations.
799
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000800- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
801
Neal Norwitze7214a12005-12-18 05:03:17 +0000802- Support for converting hex strings to floats no longer works.
803 This was not portable. float('0x3') now raises a ValueError.
804
Barry Warsaw2a38a862005-12-18 01:27:35 +0000805- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000806 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000807 is now displayed in interactive prompt banner.
808
Georg Brandlfa166682005-12-17 21:45:17 +0000809- Implementation of PEP 341 - Unification of try/except and try/finally.
810 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000811 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000812
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000813- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
814 now encodes backslash correctly.
815
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000816- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
817
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000818- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000819 and long longs.
820
Neal Norwitz67715f02005-11-09 06:59:35 +0000821- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000822 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000823 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000824
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000825- Replaced most Unicode charmap codecs with new ones using the
826 new Unicode translate string feature in the builtin charmap
827 codec; the codecs were created from the mapping tables available
828 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
829 encodings now include a mapping for the Apple logo)
830
Tim Peterse3547fd2005-12-16 23:13:57 +0000831- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000832
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000833- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000834
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000835- A new AST parser implementation was completed. The abstract
836 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000837 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000838
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000839- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000840 The following code now raises a SyntaxError: foo(a = i for i in range(10))
841
Neal Norwitz708e51a2005-10-03 04:48:15 +0000842- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
843
Neal Norwitz11bd1192005-10-03 00:54:56 +0000844- SF Bug #887946: fix segfault when redirecting stdin from a directory.
845 Provide a warning when a directory is passed on the command line.
846
Neal Norwitz40d37812005-10-02 01:48:49 +0000847- Fix segfault with invalid coding.
848
849- SF bug #772896: unknown encoding results in MemoryError.
850
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000851- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000852 supported a __len__() method which evaluated to False when the iterator
853 was empty.
854
Guido van Rossum630db602005-09-20 18:49:54 +0000855- On 64-bit platforms, when __len__() returns a value that cannot be
856 represented as a C int, raise OverflowError.
857
Skip Montanarof8948ca2005-09-19 03:54:46 +0000858- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000859 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000860
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000861- SF bug #893549: parsing keyword arguments was broken with a few format
862 codes.
863
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000864- Changes donated by Elemental Security to make it work on AIX 5.3
865 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
866 bug #105470: test_pwd fails on 64bit system (Opteron).
867
Guido van Rossum539c6622005-09-14 17:49:54 +0000868- Changes donated by Elemental Security to make it work on HP-UX 11 on
869 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
870
Georg Brandl4550b8d2005-08-26 06:43:52 +0000871- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000872 (fixes bug #1119418).
873
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000874- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
875
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000876- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
877 exceptions that cause a function to exit.
878
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000879- The implementation of set() and frozenset() was revised to use its
880 own internal data structure. Memory consumption is reduced by 1/3
881 and there are modest speed-ups as well. The API is unchanged.
882
Tim Petersde7990b2005-07-17 23:45:23 +0000883- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
884
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000885- SF bug #1229429: PyObject_CallMethod failed to decrement some
886 reference counts in some error exit cases.
887
Tim Petersecc6e6a2005-07-10 22:30:55 +0000888- SF bug #1185883: Python's small-object memory allocator took over
889 a block managed by the platform C library whenever a realloc specified
890 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000891 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000892 portable way to copy data from the C-managed block into Python's
893 small-object space without risking a memory fault. Python's small-object
894 realloc now leaves such blocks under the control of the platform C
895 realloc.
896
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000897- SF bug #1232517: An overflow error was not detected properly when
898 attempting to convert a large float to an int in os.utime().
899
Raymond Hettinger3296e692005-06-29 23:29:56 +0000900- SF bug #1224347: hex longs now print with lowercase letters just
901 like their int counterparts.
902
Michael W. Hudson188d4362005-06-20 16:52:57 +0000903- SF bug #1163563: the original fix for bug #1010677 ("thread Module
904 Breaks PyGILState_Ensure()") broke badly in the case of multiple
905 interpreter states; back out that fix and do a better job (see
906 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
907 for a longer write-up of the problem).
908
Michael W. Hudsondf888462005-06-03 14:41:55 +0000909- SF patch #1180995: marshal now uses a binary format by default when
910 serializing floats.
911
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000912- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
913 the routines that promise to produce IEEE 754 binary representations
914 of floats now simply copy bytes around.
915
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000916- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP

Brett Cannonc3647ac2005-04-26 03:45:26 +0000919- patch #1109424: int, long, float, complex, and unicode now check for the
920 proper magic slot for type conversions when subclassed. Previously the
921 magic slot was ignored during conversion. Semantics now match the way
922 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000923 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000924 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000925 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000926
Barry Warsawc8d907c2005-04-19 23:43:40 +0000927- Descriptors defined in C with a PyGetSetDef structure, where the setter is
928 NULL, now raise an AttributeError when attempting to set or delete the
929 attribute. Previously a TypeError was raised, but this was inconsistent
930 with the equivalent pure-Python implementation.
931
Michael W. Hudson774479c2005-04-18 08:46:17 +0000932- It is now safe to call PyGILState_Release() before
933 PyEval_InitThreads() (note that if there is reason to believe there
934 are multiple threads around you still must call PyEval_InitThreads()
935 before using the Python API; this fix is for extension modules that
936 have no way of knowing if Python is multi-threaded yet).
937
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000938- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
939 disabled caused a crash.
940
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000941- Bug #1165306: instancemethod_new allowed the creation of a method
942 with im_class == im_self == NULL, which caused a crash when called.
943
Tim Petersecc6e6a2005-07-10 22:30:55 +0000944- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000945 fixes the crash seen in bug #1165761
946
Raymond Hettinger96229b12005-03-11 06:49:40 +0000947- Added two new builtins, any() and all().
948
Brett Cannon409d8f22005-03-05 06:47:57 +0000949- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000950 (e.g., ``class C(): pass`` is no longer a syntax error).
951 Patch #1176012 added support to the 'parser' module and 'compiler' package
952 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000953
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000954- Patch #1115086: Support PY_LONGLONG in structmember.
955
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000956- Bug #1155938: new style classes did not check that __init__() was
957 returning None.
958
Tim Petersecc6e6a2005-07-10 22:30:55 +0000959- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000960 ('\') with a specific error message.
961
Martin v. Löwisff232d72005-03-03 09:24:38 +0000962- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
963
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000964- Bug #1124295: the __name__ attribute of file objects was
965 inadvertently made inaccessible in restricted mode.
966
Tim Petersecc6e6a2005-07-10 22:30:55 +0000967- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000968 an ferror() call.
969
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000970- min() and max() now support key= arguments with the same meaning as in
971 list.sort().
972
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000973- The peephole optimizer now performs simple constant folding in expressions:
974 (2+3) --> (5).
975
Raymond Hettingera422c342005-01-11 03:03:27 +0000976- set and frozenset objects can now be marshalled. SF #1098985.
977
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000978- Bug #1077106: Poor argument checking could cause memory corruption
979 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000980
Jeremy Hyltonab630502005-02-04 18:44:06 +0000981- The parser did not complain about future statements in illegal
982 positions. It once again reports a syntax error if a future
983 statement occurs after anything other than a doc string.
984
Neil Schemenauercf52c072005-08-12 17:34:58 +0000985- Change the %s format specifier for str objects so that it returns a
986 unicode instance if the argument is not an instance of basestring and
987 calling __str__ on the argument returns a unicode instance.
988
Tim Petersf4e69282006-02-27 17:15:31 +0000989- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
990 current thread state when the auto-GIL-state machinery knows about
991 it (since the thread state is being deleted, continuing to remember it
992 can't help, but can hurt if another thread happens to get created with
993 the same thread id).

1023 for applications that require this specific version (such as IDNA).
1024
Neal Norwitzb62c4332006-03-04 18:35:47 +00001025- The timing module is no longer built by default. It was deprecated

Anthony Baxter93f5b932006-04-03 08:05:07 +00001189- The email module's parsedate_tz function now sets the daylight savings
1190 flag to -1 (unknown) since it can't tell from the date whether it should
1191 be set.
1192
Fred Drakead5177c2006-04-01 22:14:43 +00001193- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
1194 now sport attributes that provide access to the parts of the result.
1195
Georg Brandl7f6b67c2006-04-01 08:35:18 +00001196- Patch #1462498: sgmllib now handles entity and character references
1197 in attribute values.
1198
Anthony Baxterc51ee692006-04-01 00:57:31 +00001199- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001200 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001201 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001202 module will not be built.
1203
Tim Petersc17976e2006-04-01 00:26:53 +00001204- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1205 aren't officially supported here, and trying to use them will probably
1206 raise an exception some day. But dicts have been allowed, and "mostly
1207 worked", so support for them won't go away without warning.
1208
Georg Brandl338ef7d2006-03-31 18:42:16 +00001209- Bug #1445068: getpass.getpass() can now be given an explicit stream
1210 argument to specify where to write the prompt.
1211

1218 key to be used for signing the uploaded code.
1219
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001220- Queue.Queue objects now support .task_done() and .join() methods
1221 to make it easier to monitor when daemon threads have completed
1222 processing all enqueued tasks. Patch #1455676.
1223
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001224- popen2.Popen objects now preserve the command in a .cmd attribute.
1225
Thomas Hellerc61c0492006-03-22 10:09:27 +00001226- Added the ctypes ffi package.
1227
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001228- email 4.0 package now integrated. This is largely the same as the email 3.0
1229 package that was included in Python 2.3, except that PEP 8 module names are
1230 now used (e.g. mail.message instead of email.Message). The MIME classes
1231 have been moved to a subpackage (e.g. email.mime.text instead of
1232 email.MIMEText). The old names are still supported for now. Several
1233 deprecated Message methods have been removed and lots of bugs have been
1234 fixed. More details can be found in the email package documentation.
1235
Walter Dörwald40108c92006-03-27 08:15:44 +00001236- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1237 (a subclass of tuple) that provides incremental decoders and encoders
1238 (a way to use stateful codecs without the stream API). Python functions
1239 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1240 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1241 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001242
Walter Dörwald067db482006-03-15 22:17:27 +00001243- Patch #1359365: Calling next() on a closed StringIO.String object raises
1244 a ValueError instead of a StopIteration now (like file and cString.String do).
1245 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1246 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001247
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001248- A regrtest option -w was added to re-run failed tests in verbose mode.

1251 interpreter to exit.
1252
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001253- The function get_count() has been added to the gc module, and gc.collect()
1254 grew an optional 'generation' argument.
1255
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001256- A library msilib to generate Windows Installer files, and a distutils

1260 and helpful context managers nested() and closing().
1261

Tim Peterse3547fd2005-12-16 23:13:57 +00001320 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1321 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1322 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1323 Ronald L. Rivest offered this advice for Python:
1324
1325 "The consensus of researchers in this area (at least as
1326 expressed at the NIST Hash Function Workshop 10/31/05),
1327 is that SHA-256 is a good choice for the time being, but
1328 that research should continue, and other alternatives may
1329 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001330
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001331- Added a subset of Fredrik Lundh's ElementTree package. Available

Walter Dörwalda05834e2005-10-09 19:38:21 +00001385 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001386

1402 parameter, but uses the usual "kwargs=None".
1403
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001404- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1424 Bug #1224621.
1425
Raymond Hettinger68c04532005-06-10 11:05:19 +00001426- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001427 roundtrip from lexed tokens back to Python source code. In addition,

1439 class at all.
1440
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001441- distutils.commands.upload was added to support uploading distribution

Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001452- Bug #1163325: Decimal infinities failed to hash. Attempting to
1453 hash a NaN raised an InvalidOperation instead of a TypeError.
1454
Tim Petersecc6e6a2005-07-10 22:30:55 +00001455- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001456 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1457

Martin v. Löwisa4dac402005-03-03 11:39:45 +00001467 profile.py if available.
1468
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001469- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1470

1485
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001486- Patch #1049151: xdrlib now unpacks booleans as True or False.
1487
Raymond Hettingerbab41432005-02-05 01:31:19 +00001488- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1489
Guido van Rossumd0641422005-02-03 15:01:24 +00001490- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1491 disables recursive traversal through instance attributes, which can
1492 be exploited in various ways.
1493
Tim Peterse3547fd2005-12-16 23:13:57 +00001494- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001495 flags on the HTTP listening socket.
1496
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001497- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1498 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1499
Tim Peterse3547fd2005-12-16 23:13:57 +00001500- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001501 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1502
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001503- Bug #1110478: Revert os.environ.update to do putenv again.
1504
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001505- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1506
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001507- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1508
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001509- Enhancements to the csv module:
1510
1511 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001512 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001513 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001514 + Dialect parameter parsing has been re-implemented to improve error
1515 reporting.
1516 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1517 dictates.
1518 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001519 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001520 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001521 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1522 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001523 + reader now allows \r characters to be quoted (previously it only allowed
1524 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001525 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001526 + Dialect classes passed to the module are no longer instantiated by
1527 the module before being parsed (the former validation scheme required
1528 this, but the mechanism was unreliable).
1529 + The dialect registry now contains instances of the internal
1530 C-coded dialect type, rather than references to python objects.
1531 + the internal c-coded dialect type is now immutable.
1532 + register_dialect now accepts the same keyword dialect specifications
1533 as the reader and writer, allowing the user to register dialects
1534 without first creating a dialect class.
1535 + a configurable limit to the size of parsed fields has been added -
1536 previously, an unmatched quote character could result in the entire
1537 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001538 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001539 the parser field size limit (returning the former limit). The initial
1540 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001541 + A line_num attribute has been added to the reader object, which tracks
1542 the number of lines read from the source iterator. This is not
1543 the same as the number of records returned, as records can span
1544 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001545 + reader and writer objects were not being registered with the cyclic-GC.
1546 This has been fixed.
1547
Brett Cannone6539c42005-01-08 02:43:53 +00001548- _DummyThread objects in the threading module now delete self.__block that is
1549 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1550 lock primitives tend to be limited in number and thus should not be wasted on
1551 a _DummyThread object. Fixes bug #1089632.
1552
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001553- The imghdr module now detects Exif files.
1554
Raymond Hettinger6065d322004-12-20 23:51:53 +00001555- StringIO.truncate() now correctly adjusts the size attribute.
1556 (Bug #951915).
1557
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001558- locale.py now uses an updated locale alias table (built using
1559 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1560 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001561 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001562
Raymond Hettinger3557f422004-12-07 12:02:02 +00001563- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1564
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001565- the pickle module no longer accepts the deprecated None option in the
1566 args tuple returned by __reduce__().
1567
Brett Cannon84667c02004-12-07 03:25:18 +00001568- optparse now optionally imports gettext. This allows its use in setup.py.
1569
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001570- the pickle module no longer uses the deprecated bin parameter.
1571
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001572- the shelve module no longer uses the deprecated binary parameter.
1573
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001574- the pstats module no longer uses the deprecated ignore() method.
1575
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001576- the filecmp module no longer uses the deprecated use_statcache argument.
1577
Raymond Hettinger664347b2004-12-04 21:21:53 +00001578- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1579 extended or overridden by subclasses. Formerly, the subclassed method would
1580 be ignored by the rest of the module. (Bug #1078905).
1581
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001582- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001583 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001584
Walter Dörwald36733692004-12-22 12:50:50 +00001585- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1586 once when a size argument is given. This prevents a buffer overflow in the
1587 tokenizer with very long source lines.
1588
Barry Warsaw538561e2006-01-01 21:48:54 +00001589- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1590 immediately after creating the object, without any intervening
1591 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001592
Skip Montanaro05885812005-01-16 20:48:27 +00001593- The reconvert.quote function can now emit triple-quoted strings. The
1594 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001595
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001596- ``UserString.MutableString`` now supports negative indices in
1597 ``__setitem__`` and ``__delitem__``
1598
Greg Ward40407942005-03-05 02:53:17 +00001599- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1600 correctly.
1601
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001602- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1603 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1604 character even if the user has passed a size parameter to get a proper
1605 line ending. Remove the special handling of a "\r\n" that has been split
1606 between two lines.
1607
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001608- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1609 about illegal code points. The codec now supports PEP 293 style error
1610 handlers.
1611
Walter Dörwald78a78b02005-09-01 12:04:29 +00001612- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001613 from the input stream, so that the output is a byte string in the correct
1614 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001615
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001616- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1617 considering it exactly like a '*'.
1618
Walter Dörwald007f8df2005-10-09 19:42:27 +00001619- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1620 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001621
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001622- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1623
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001624- Patch #1413711: Certain patterns of differences were making difflib
1625 touch the recursion limit.
1626
Walter Dörwald58917a62006-03-31 15:26:22 +00001627- Bug #947906: An object oriented interface has been added to the calendar
1628 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001629 called as a script (e.g. via ``python -mcalendar``). Localized month and
1630 weekday names can be ouput (even if an exotic encoding is used) using
1631 special classes that use unicode.

1634-----
1635
Neal Norwitz602d3392006-03-31 08:21:40 +00001636- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1637 by using -mieee gcc option.
1638
Martin v. Löwis86d66262006-02-17 08:40:11 +00001639- Patch #1432345: Make python compile on DragonFly.
1640
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001641- Build support for Win64-AMD64 was added.
1642
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001643- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1644
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001645- Patch #881820: look for openpty and forkpty also in libbsd.
1646
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001647- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1648 The zlib module is now builtin on Windows.
1649
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001650- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1651
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001652- Bug #1189330: configure did not correctly determine the necessary
1653 value of LINKCC if python was built with GCC 4.0.
1654
Trent Mick8321b422005-07-26 02:29:21 +00001655- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1656 vulnerability in zlib 1.2.1 and 1.2.2.
1657
Brett Cannon08cd5982005-04-24 22:26:38 +00001658- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1659 flags that change binary compatibility. Changes were also made to
1660 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001661 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001662
Bob Ippolitoed233462005-03-29 13:47:59 +00001663- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1664 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1665 no longer exists). This configure patch makes things right.
1666
Martin v. Löwise2713be2005-03-08 15:03:08 +00001667- Bug #1158607: Build with --disable-unicode again.
1668
Brett Cannon46d96232005-02-16 00:07:19 +00001669- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1670 defined. Discovered as a result of not being able to build on OS X.
1671
Brett Cannon516592f2004-12-07 00:42:59 +00001672- setup.py now uses the directories specified in LDFLAGS using the -L option
1673 and in CPPFLAGS using the -I option for adding library and include
1674 directories, respectively, for compiling extension modules against. This has
1675 led to the core being compiled using the values in CPPFLAGS. It also removes
1676 the need for the special-casing of both DarwinPorts and Fink for darwin since
1677 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1678 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1679 Fink, ``-I/opt/local/include`` for DarwinPorts).
1680
Brett Cannon43802422005-02-10 20:48:03 +00001681- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1682 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1683 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1684 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001686C API
1687-----
1688
Tim Petersc9d78aa2006-03-26 23:27:58 +00001689- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1690 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1691 is obtained via the ``PyObject_`` family, it must be released via the
1692 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1693 always been officially true, but when Python's small-object allocator was
1694 introduced, an attempt was made to cater to a few extension modules
1695 discovered at the time that obtained memory via ``PyObject_New`` but
1696 released it via ``PyMem_DEL``. It's years later, and if such code still
1697 exists it will fail now (probably with segfaults, but calling wrong
1698 low-level memory management functions can yield many symptoms).
1699
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001700- Added a C API for set and frozenset objects.
1701
Raymond Hettinger66517482004-12-03 11:45:13 +00001702- Removed PyRange_New().
1703
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001704- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1705 mapping argument now. This string is used as a mapping table. Byte values
1706 greater than the length of the string and 0xFFFE are treated as undefined
1707 mappings.
