Georg Brandl9dceedb2006-07-12 15:31:17 +000015- Patch #1521179: Python now accepts the standard options ``--help`` and
16 ``--version`` as well as ``/?`` on Windows.
17
Neal Norwitza1f10902006-07-12 07:28:29 +000018- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
19 again. Fixing this problem required changing the .pyc magic number.
20 This means that .pyc files generated before 2.5c1 will be regenerated.

Thomas Hellerce049a02006-07-14 17:51:14 +000030- Patch #1521817: Index range checking on ctypes arrays containing
31 exactly one element enabled again. This allows iterating over these
32 arrays, without the need to check the array size before.
33
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000034- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000035 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000036 /dev/null in certain cases; this is now fixed.
37
Thomas Heller47d7a062006-07-12 08:43:47 +000038- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
39 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000040
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000041- Because of a misspelled preprocessor symbol, ctypes was always
42 compiled without thread support; this is now fixed.

49Core and builtins
50-----------------
51
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000052- Bug #1441486: The literal representation of -(sys.maxint - 1)
53 again evaluates to a int object, not a long.
54
Neil Schemenauer0e07b602006-07-09 16:16:34 +000055- Bug #1501934: The scope of global variables that are locally assigned
56 using augmented assignment is now correctly determined.
57
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000058- Bug #927248: Recursive method-wrapper objects can now safely
59 be released.
60
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000061- Bug #1417699: Reject locale-specific decimal point in float()
62 and atof().
63
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000064- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
65 omit a default "error" argument for NULL pointer. This allows
66 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000067
Neal Norwitzfb48afa2006-07-08 05:31:37 +000068- Bug #1519018: 'as' is now validated properly in import statements.
69
Neal Norwitz28746ab2006-07-09 22:14:42 +000070- On 64 bit systems, int literals that use less than 64 bits are
71 now ints rather than longs.
72
Neal Norwitzed657552006-07-10 00:04:44 +000073- Bug #1512814, Fix incorrect lineno's when code at module scope
74 started after line 256.
75
Tim Peters32a83612006-07-10 21:08:24 +000076- New function ``sys._current_frames()`` returns a dict mapping thread
77 id to topmost thread stack frame. This is for expert use, and is
78 especially useful for debugging application deadlocks. The functionality
79 was previously available in Fazal Majid's ``threadframe`` extension
80 module, but it wasn't possible to do this in a wholly threadsafe way from
81 an extension.

87
Tim Peters32a83612006-07-10 21:08:24 +000088- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +000089 environment variable to be set in order to the SDK environment
90 for finding the compiler, include files, etc.
91
Martin v. Löwis388a8c22006-07-06 19:28:03 +000092- Bug #1515998: Properly generate logical ids for files in bdist_msi.
93
Nick Coghlan2d792252006-07-06 13:47:18 +000094- warnings.py now ignores ImportWarning by default
95
Thomas Woutersadd19112006-07-05 11:03:49 +000096- string.Template() now correctly handles tuple-values. Previously,
97 multi-value tuples would raise an exception and single-value tuples would
98 be treated as the value they contain, instead.
99
Martin v. Löwisede77f52006-07-03 13:01:35 +0000100- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
101 even if some data are received.
102
Martin v. Löwis45482392006-07-03 12:28:58 +0000103- Bug #1267547: Put proper recursive setup.py call into the
104 spec file generated by bdist_rpm.
105
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000106- Bug #1514693: Update turtle's heading when switching between
107 degrees and radians.
108

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000110 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000111
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000112- Bug #1514703: Only setup canvas window in turtle when the canvas
113 is created.
114
Martin v. Löwis7596e832006-07-01 15:33:37 +0000115- Bug #1513223: .close() of a _socketobj now releases the underlying
116 socket again, which then gets closed as it becomes unreferenced.
117
Fred Drake10497c82006-06-29 02:57:48 +0000118- Bug #1504333: Make sgmllib support angle brackets in quoted
119 attribute values.
120
121- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
122 sgmllib ('[' and ']' were not accepted).
123
Georg Brandl1be63af2006-06-28 20:23:25 +0000124- Fix a bug in the turtle module's end_fill function.
125
Brett Cannon53ab5b72006-06-22 16:49:14 +0000126- Bug #1510580: The 'warnings' module improperly required that a Warning
127 category be either a types.ClassType and a subclass of Warning. The proper
128 check is just that it is a subclass with Warning as the documentation states.
129
Georg Brandlad29e632006-06-21 17:45:17 +0000130- The compiler module now correctly compiles the new try-except-finally
131 statement (bug #1509132).
132
Neal Norwitz60373cd2006-06-22 06:30:50 +0000133- The wsgiref package is now installed properly on Unix.
134
Vinay Sajip28e57612006-07-01 10:45:20 +0000135- A bug was fixed in logging.config.fileConfig() which caused a crash on
136 shutdown when fileConfig() was called multiple times.
137
Gerhard Häring762fbd32006-07-02 17:48:30 +0000138- The sqlite3 module did cut off data from the SQLite database at the first
139 null character before sending it to a custom converter. This has been fixed
140 now.
141
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000142Extension Modules
143-----------------
144
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000145- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
146 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
147 The patch makes sockets use poll() internally where available.
148
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000149- Assigning None to pointer type fields in ctypes structures possible
150 overwrote the wrong fields, this is fixed now.
151
152- Fixed a segfault in _ctypes when ctypes.wintypes were imported
153 on non-Windows platforms.
154
155- Bug #1518190: The ctypes.c_void_p constructor now accepts any
156 integer or long, without range checking.
157
158- Patch #1517790: It is now possible to use custom objects in the ctypes
159 foreign function argtypes sequence as long as they provide a from_param
160 method, no longer is it required that the object is a ctypes type.
161
162- The '_ctypes' extension module now works when Python is configured
163 with the --without-threads option.
164
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000165- Bug #1513646: os.access on Windows now correctly determines write
166 access, again.
167
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000168- Bug #1512695: cPickle.loads could crash if it was interrupted with
169 a KeyboardInterrupt.
170
Neal Norwitza12aa882006-07-06 06:45:08 +0000171- Bug #1296433: parsing XML with a non-default encoding and
172 a CharacterDataHandler could crash the interpreter in pyexpat.
173
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000174- Patch #1516912: improve Modules support for OpenVMS.
175
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000176Build
177-----
178
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000179- Automate Windows build process for the Win64 SSL module.
180
Tim Peters32a83612006-07-10 21:08:24 +0000181- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000182 Previously, the slight difference could cause compilation errors of the
183 'zlib' module on systems with more than one version of zlib.
184
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000185- The MSI compileall step was fixed to also support a TARGETDIR
186 with spaces in it.
187
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000188- Bug #1517388: sqlite3.dll is now installed on Windows independent
189 of Tcl/Tk.
190
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000191- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000192 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000193
Neal Norwitzb15ac312006-06-29 04:10:08 +0000194Tests
195-----
196
197- Call os.waitpid() at the end of tests that spawn child processes in order
198 to minimize resources (zombies).
199

201-------------
202
Nick Coghlan2d792252006-07-06 13:47:18 +0000203- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
204 documentation for the warnings module.
205
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000206- Patch #1509163: MS Toolkit Compiler no longer available.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000210What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000211================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000212
Anthony Baxterd1136802006-06-19 12:04:15 +0000213*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000214
215Core and builtins
216-----------------
217
Georg Brandla56b9152006-06-19 06:35:54 +0000218- Patch #1507676: Error messages returned by invalid abstract object operations
219 (such as iterating over an integer) have been improved and now include the
220 type of the offending object to help with debugging.
221
Brett Cannonea3912b2006-06-13 21:46:41 +0000222- Bug #992017: A classic class that defined a __coerce__() method that returned
223 its arguments swapped would infinitely recurse and segfault the interpreter.
224
Neal Norwitz909eb122006-06-12 02:13:21 +0000225- Fix the socket tests so they can be run concurrently.
226
Neal Norwitzb9845e72006-06-12 02:11:18 +0000227- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000228 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000229
Brett Cannon22565aa2006-06-09 22:31:23 +0000230- Bug #532646: object.__call__() will continue looking for the __call__
231 attribute on objects until one without one is found. This leads to recursion
232 when you take a class and set its __call__ attribute to an instance of the
233 class. Originally fixed for classic classes, but this fix is for new-style.
234 Removes the infinite_rec_3 crasher.
235
Georg Brandl24250812006-06-09 18:45:48 +0000236- The string and unicode methods startswith() and endswith() now accept
237 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
238
Brett Cannonde3b0522006-06-08 17:00:45 +0000239- Buffer objects, at the C level, never used the char buffer
240 implementation even when the char buffer for the wrapped object was
241 explicitly requested (originally returned the read or write buffer).
242 Now a TypeError is raised if the char buffer is not present but is
243 requested.
244
Georg Brandlddbaa662006-06-04 21:56:52 +0000245- Patch #1346214: Statements like "if 0: suite" are now again optimized
246 away like they were in Python 2.4.
247
Georg Brandlb7c8f542006-05-27 12:30:25 +0000248- Builtin exceptions are now full-blown new-style classes instead of
249 instances pretending to be classes, which speeds up exception handling
250 by about 80% in comparison to 2.5a2.
251
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000252- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
253 Unicode 4.1.
254
Georg Brandlf4ef1162006-05-26 18:03:31 +0000255- Patch #921466: sys.path_importer_cache is now used to cache valid and
256 invalid file paths for the built-in import machinery which leads to
257 fewer open calls on startup.
258
Tim Peters696cf432006-05-24 21:10:40 +0000259- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
260 of-2 bases. The largest speedup is for inputs with about 1000 decimal
261 digits. Conversion from non-power-of-2 bases remains quadratic-time in
262 the number of input digits (it was and remains linear-time for bases
263 2, 4, 8, 16 and 32).
264
Tim Petersb713ec22006-05-23 18:45:30 +0000265- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
266 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
267 an integer close to ``sys.maxint``. This was repaired by patch
268 #1335972, which also gives a nice speedup.
269
Richard Jonescebbefc2006-05-23 18:28:17 +0000270- Patch #1337051: reduced size of frame objects.
271
272- PyErr_NewException now accepts a tuple of base classes as its
273 "base" parameter.
274
Richard Jones7c88dcc2006-05-23 10:37:38 +0000275- Patch #876206: function call speedup by retaining allocated frame
276 objects.
277
Georg Brandl7b90e162006-05-18 07:01:27 +0000278- Bug #1462152: file() now checks more thoroughly for invalid mode
279 strings and removes a possible "U" before passing the mode to the
280 C library function.
281
Neal Norwitz1004a532006-05-15 07:17:23 +0000282- Patch #1488312, Fix memory alignment problem on SPARC in unicode
283
Neal Norwitz373f0a72006-05-15 07:04:36 +0000284- Bug #1487966: Fix SystemError with conditional expression in assignment
285
Martin v. Löwis879768d2006-05-11 13:28:43 +0000286- WindowsError now has two error code attributes: errno, which carries
287 the error values from errno.h, and winerror, which carries the error
288 values from winerror.h. Previous versions put the winerror.h values
289 (from GetLastError()) into the errno attribute.
290
Martin v. Löwis77736712006-05-04 05:51:03 +0000291- Patch #1475845: Raise IndentationError for unexpected indent.
292
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000293- Patch #1479181: split open() and file() from being aliases for each other.
294
Tim Peters44bd9862006-06-01 13:49:23 +0000295- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
296 methods were always silently ignored by dictionaries when comparing keys.
297 They are now passed through (except when using the C API function
298 ``PyDict_GetItem()``, whose semantics did not change).
299
300- Bug #1456209: In some obscure cases it was possible for a class with a
301 custom ``__eq__()`` method to confuse dict internals when class instances
302 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
303 No, you don't have any code that did this ;-)

309
310- Patch #1462338: Upgrade pyexpat to expat 2.0.0
311
Brett Cannon6ee7d012006-06-08 16:23:04 +0000312- Change binascii.hexlify to accept a read-only buffer instead of only a char
313 buffer and actually follow its documentation.
314
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000315- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000317- Patch #1478788 (modified version): The functional extension module has
318 been renamed to _functools and a functools Python wrapper module added.
319 This provides a home for additional function related utilities that are
320 not specifically about functional programming. See PEP 309.
321
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000322- Patch #1493701: performance enhancements for struct module.
323
Georg Brandl378d5922006-05-17 14:26:50 +0000324- Patch #1490224: time.altzone is now set correctly on Cygwin.
325
Georg Brandl8d3342b2006-05-16 07:38:27 +0000326- Patch #1435422: zlib's compress and decompress objects now have a
327 copy() method.
328
Andrew MacIntyre92913322006-06-13 15:04:24 +0000329- Patch #1454481: thread stack size is now tunable at runtime for thread
330 enabled builds on Windows and systems with Posix threads support.
331
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000332- On Win32, os.listdir now supports arbitrarily-long Unicode path names
333 (up to the system limit of 32K characters).
334
335- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
336 As a result, these functions now raise WindowsError instead of OSError.
337
Tim Peters7a822da2006-05-25 21:50:17 +0000338- ``time.clock()`` on Win64 should use the high-performance Windows
339 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
340 Windows platforms).
341
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000342- Calling Tk_Init twice is refused if the first call failed as that
343 may deadlock.
344
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000345- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
346 accept it without potentially using an uninitialized pointer.
347
348- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
349 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
350 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000351
Gregory P. Smith372b5832006-06-05 18:48:21 +0000352- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000353 [pybsddb project SF patch number 1466734]
354
Gregory P. Smith372b5832006-06-05 18:48:21 +0000355- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
356 parameter is supplied. [SF pybsddb bug #1477863]
357
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000358- bsddb: the __len__ method of a DB object has been fixed to return correct
359 results. It could previously incorrectly return 0 in some cases.
360 Fixes SF bug 1493322 (pybsddb bug 1184012).
361
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000362- bsddb: the bsddb.dbtables Modify method now raises the proper error and
363 aborts the db transaction safely when a modifier callback fails.
364 Fixes SF python patch/bug #1408584.
365
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000366- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000367 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000368 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
369 database calls that would previously deadlock. [SF python bug #775414]
370
Vinay Sajip28e57612006-07-01 10:45:20 +0000371- Patch #1446489: add support for the ZIP64 extensions to zipfile.

393 mime.types file for determining MIME types.
394
Georg Brandl2605ca82006-06-14 06:08:31 +0000395- Bug #1339007: Shelf objects now don't raise an exception in their
396 __del__ method when initialization failed.
397
Martin v. Löwisd8251432006-06-14 05:21:04 +0000398- Patch #1455898: The MBCS codec now supports the incremental mode for
399 double-byte encodings.
400
Tim Peters43898b42006-06-14 04:09:25 +0000401- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
402 guarantee that adjacent triples in the return list always describe
403 non-adjacent blocks. Previously, a pair of matching blocks could end
404 up being described by multiple adjacent triples that formed a partition
405 of the matching pair.
406
Greg Ward0e0c9f42006-06-11 16:24:11 +0000407- Bug #1498146: fix optparse to handle Unicode strings in option help,
408 description, and epilog.
409
Greg Wardd1c797e2006-06-11 14:42:41 +0000410- Bug #1366250: minor optparse documentation error.

413 clarify docs.
414
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000415- The wsgiref package has been added to the standard library.
416
Nick Coghlan676725d2006-06-08 13:54:49 +0000417- The functions update_wrapper() and wraps() have been added to the functools
418 module. These make it easier to copy relevant metadata from the original
419 function when writing wrapper functions.
420
Tim Petersd6a9eef2006-06-05 01:48:21 +0000421- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
422 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000423
Martin v. Löwis3f767792006-06-04 19:36:28 +0000424- Patch #1359618: Speed up charmap encoder by using a trie structure
425 for lookup.
426
Tim Petersd609b1a2006-06-02 23:22:51 +0000427- The functions in the ``pprint`` module now sort dictionaries by key
428 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
429 if and only if its display required more than one line, although that
430 wasn't documented. The new behavior increases predictability; e.g.,
431 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
432
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000433- Patch #1497027: try HTTP digest auth before basic auth in urllib2
434 (thanks for J. J. Lee).
435
Georg Brandl2b330372006-05-28 20:23:12 +0000436- Patch #1496206: improve urllib2 handling of passwords with respect to
437 default HTTP and HTTPS ports.
438
George Yoshidaf3c65de2006-05-28 16:39:09 +0000439- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
440
Bob Ippolito7298f272006-05-23 18:43:47 +0000441- Patch #1281707: speed up gzip.readline.
442
Georg Brandlb89316f2006-05-17 15:51:16 +0000443- Patch #1180296: Two new functions were added to the locale module:
444 format_string() to get the effect of "format % items" but locale-aware,
445 and currency() to format a monetary number with currency sign.
446
Georg Brandle3a25832006-05-17 14:56:04 +0000447- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
448 and several features added, such as speed and geometry control.
449
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000450- Patch #1488881: add support for external file objects in bz2 compressed
451 tarfiles.
452
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000453- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
454 stdout arguments, making it possible to redirect input and output
455 for remote debugging.
456
457- Patch #1484695: Update the tarfile module to version 0.8. This fixes
458 a couple of issues, notably handling of long file names using the
459 GNU LONGNAME extension.
460
461- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
462 new flag when ``name`` is already the name of an option flag.
463
464- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
465 package.
466
467- Patch #1472854: make the rlcompleter.Completer class usable on non-
468 UNIX platforms.
469
470- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
471
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000472- Bug #1472827: correctly escape newlines and tabs in attribute values in

506*Release date: 27-APR-2006*
507
508Core and builtins
509-----------------
510
Thomas Heller1b046642006-04-18 18:51:06 +0000511- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
512 by converting these apis from macros into exported functions again:
513
514 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
515 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
516 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
517 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
518 PyRun_String Py_CompileString
519
Martin v. Löwis45294a92006-04-18 06:24:08 +0000520- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
521
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000522- All uses of PyStructSequence_InitType have been changed to initialize
523 the type objects only once, even if the interpreter is initialized
524 multiple times.
525
Neal Norwitz61546162006-04-14 05:20:28 +0000526- Bug #1454485, array.array('u') could crash the interpreter. This was
527 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
528 to unicode when it didn't make sense. 'u#' now requires a unicode string.
529
530- Py_UNICODE is unsigned. It was always documented as unsigned, but
531 due to a bug had a signed value in previous versions.
532
Tim Peters3a5e8b12006-04-11 01:44:07 +0000533- Patch #837242: ``id()`` of any Python object always gives a positive
534 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
535 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000536 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000537 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000538
Tim Peters3a5e8b12006-04-11 01:44:07 +0000539 def __hash__(self):
540 return id(self) # WRONG
541
542 because a hash result must be a (short) Python int but it was always
543 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000544 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000545 was always usable as a hash value before this patch. That's no longer
546 necessarily so.
547
548- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000549 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000550 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000551 #1454844)
552
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000553- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
554 involving generators that have paused outside of any ``try`` or ``with``
555 blocks. (In 2.5a1, a paused generator that was part of a reference
556 cycle could not be garbage collected, regardless of whether it was
557 paused in a ``try`` or ``with`` block.)

574 a temporary db (file=None) with the 'n' flag to truncate on open.
575
576- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
577 as older versions cause excessive test failures.

583-------
584
Peter Astrand7d1d4362006-07-14 14:04:45 +0000585- Bug #1223937: subprocess.CalledProcessError reports the exit status
586 of the process using the returncode attribute, instead of
587 abusing errno.
588
Tim Peters711bf302006-04-25 03:31:36 +0000589- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
590 a doctest to be skipped (the code is not run, and the expected output
591 or exception is ignored).
592
Nick Coghlanda2268f2006-04-24 04:37:15 +0000593- Fixed contextlib.nested to cope with exceptions being raised and
594 caught inside exit handlers.
595
Greg Wardab05edc2006-04-23 03:47:58 +0000596- Updated optparse module to Optik 1.5.1 (allow numeric constants in
597 hex, octal, or binary; add ``append_const`` action; keep going if
598 gettext cannot be imported; added ``OptionParser.destroy()`` method;
599 added ``epilog`` for better help generation).
600
Tim Peters21fbd572006-04-21 21:18:10 +0000601- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
602 called from a thread spawned as a side effect of importing a module.
603
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000604- The pydoc module now supports documenting packages contained in
605 .zip or .egg files.
606
607- The pkgutil module now has several new utility functions, such
608 as ``walk_packages()`` to support working with packages that are either
609 in the filesystem or zip files.
610
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000611- The mailbox module can now modify and delete messages from
612 mailboxes, in addition to simply reading them. Thanks to Gregory
613 K. Johnson for writing the code, and to the 2005 Google Summer of
614 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000615
Tim Petersc7605f22006-04-17 21:12:33 +0000616- The ``__del__`` method of class ``local`` in module ``_threading_local``
617 returned before accomplishing any of its intended cleanup.
618
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000619- Patch #790710: Add breakpoint command lists in pdb.

624
Anthony Baxtere29002c2006-04-12 12:07:31 +0000625- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
626 Windows. Bug #1469163.
627
Phillip J. Eby47032112006-04-11 01:07:43 +0000628- The warnings, linecache, inspect, traceback, site, and doctest modules
629 were updated to work correctly with modules imported from zipfiles or
630 via other PEP 302 __loader__ objects.
631
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000632- Patch #1467770: Reduce usage of subprocess._active to processes which
633 the application hasn't waited on.
634

643-----
644
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000645- The Makefile now has a reindent target, which runs reindent.py on
646 the library.
647
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000648- Patch #1470875: Building Python with MS Free Compiler
649
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000650- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000651
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000652- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
653 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000654 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000655 CXX from --with-cxx-main, see description in README.
656
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000657- Patch #1429775: Link extension modules with the shared libpython.
658
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000659- Fixed a libffi build problem on MIPS systems.
660
Tim Peters8931ff12006-05-13 23:28:20 +0000661- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
662 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
663 and "%zu" for unsigned integers of type ``size_t``.
664
Anthony Baxter51bcb682006-04-05 14:51:42 +0000665Tests
666-----
667
Nick Coghlanda2268f2006-04-24 04:37:15 +0000668- test_contextlib now checks contextlib.nested can cope with exceptions
669 being raised and caught inside exit handlers.
670
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000671- test_cmd_line now checks operation of the -m and -c command switches
672
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000673- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
674 it separately and by hand. It also wasn't cleaning up its changes to
675 the current Decimal context.
676
Thomas Woutersabd08882006-04-26 15:53:30 +0000677- regrtest.py now has a -M option to run tests that test the new limits of
678 containers, on 64-bit architectures. Running these tests is only sensible
679 on 64-bit machines with more than two gigabytes of memory. The argument
680 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000688Documentation
689-------------
690
Tim Petersb06d28c2006-05-12 01:57:59 +0000691- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
692
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000693- PEP 343: Added Context Types section to the library reference
694 and attempted to bring other PEP 343 related documentation into
695 line with the implementation and/or python-dev discussions.
696
Tim Peters8dc73d22006-04-24 02:03:16 +0000697- Bug #1337990: clarified that ``doctest`` does not support examples
698 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000701What's New in Python 2.5 alpha 1?
702=================================
703
Anthony Baxterebed3f62006-04-03 15:03:44 +0000704*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000705
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000706Core and builtins
707-----------------
708
Nick Coghlan43832302006-04-23 17:04:07 +0000709- PEP 338: -m command line switch now delegates to runpy.run_module
710 allowing it to support modules in packages and zipfiles
711
Martin v. Löwisc661b882006-04-20 04:54:23 +0000712- On Windows, .DLL is not an accepted file name extension for
713 extension modules anymore; extensions are only found if they
714 end in .PYD.
715
Martin v. Löwisea62d252006-04-03 10:56:49 +0000716- Bug #1421664: sys.stderr.encoding is now set to the same value as
717 sys.stdout.encoding.
718
Neal Norwitz92e212f2006-04-03 04:48:37 +0000719- __import__ accepts keyword arguments.
720
Georg Brandlccadf842006-03-31 18:54:53 +0000721- Patch #1460496: round() now accepts keyword arguments.
722
Anthony Baxter262c00a2006-03-30 10:53:17 +0000723- Fixed bug #1459029 - unicode reprs were double-escaped.
724
Hye-Shik Changd478f342006-03-23 12:32:36 +0000725- Patch #1396919: The system scope threads are reenabled on FreeBSD
726 5.4 and later versions.
727
Neal Norwitze98ccf62006-03-23 05:39:47 +0000728- Bug #1115379: Compiling a Unicode string with an encoding declaration
729 now gives a SyntaxError.
730
Georg Brandlabd1ff82006-03-18 07:59:59 +0000731- Previously, Python code had no easy way to access the contents of a
732 cell object. Now, a ``cell_contents`` attribute has been added
733 (closes patch #1170323).
734
Tim Peterscf79aac2006-03-16 01:14:46 +0000735- Patch #1123430: Python's small-object allocator now returns an arena to
736 the system ``free()`` when all memory within an arena becomes unused
737 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
738 freed. Some applications will see a drop in virtual memory size now,
739 especially long-running applications that, from time to time, temporarily
740 use a large number of small objects. Note that when Python returns an
741 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000742 platform C library will in turn return that memory to the operating system.
743 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000744 appears to be effective at least on Microsoft C and gcc-based systems.
745 Thanks to Evan Jones for hard work and patience.
746
Georg Brandl533ff6f2006-03-08 18:09:27 +0000747- Patch #1434038: property() now uses the getter's docstring if there is
748 no "doc" argument given. This makes it possible to legitimately use
749 property() as a decorator to produce a read-only property.
750
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000751- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
752 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
753 of requiring an int or long in slicing and a few other contexts, enabling
754 other objects (e.g. Numeric Python's integers) to be used as slice indices.
755
Neal Norwitz995acdf2006-03-07 05:01:00 +0000756- Fixed various bugs reported by Coverity's Prevent tool.
757
Brett Cannonbf364092006-03-01 04:25:17 +0000758- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
759 new exception base class, BaseException, which has a new message attribute.
760 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
761 Raising a string exception now raises a DeprecationWarning.
762
Thomas Woutersfb609f42006-02-28 16:37:25 +0000763- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
764 explicitly relative, using 'from .module import name' to mean 'from the same
765 package as this module is in. Imports without dots still default to the
766 old relative-then-absolute, unless 'from __future__ import
767 absolute_import' is used.
768
Brett Cannona7446e32006-02-27 23:39:10 +0000769- Properly check if 'warnings' raises an exception (usually when a filter set
770 to "error" is triggered) when raising a warning for raising string
771 exceptions.
772
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000773- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000774 The name was removed from Include/code.h.
775
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000776- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000777
Guido van Rossum1968ad32006-02-25 22:38:04 +0000778- Patch 1433928:
779 - The copy module now "copies" function objects (as atomic objects).
780 - dict.__getitem__ now looks for a __missing__ hook before raising
781 KeyError.
782
Tim Peters84ef21c2006-02-28 20:39:06 +0000783- PEP 343: with statement implemented. Needs ``from __future__ import
784 with_statement``. Use of 'with' as a variable will generate a warning.
785 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000786 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000787 The following objects have __context__ methods:
788 - The built-in file type.
789 - The thread.LockType type.
790 - The following types defined by the threading module:
791 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
792 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000793
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000794- Fix the encodings package codec search function to only search
795 inside its own package. Fixes problem reported in patch #1433198.
796
797 Note: Codec packages should implement and register their own
798 codec search function. PEP 100 has the details.
799
Tim Peters9ea89d22006-06-04 03:26:02 +0000800- PEP 353: Using ``Py_ssize_t`` as the index type.
801
802- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
803 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
804 now allow Python to make use of memory blocks exceeding 2**32 bytes for
805 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
806 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000807
Neal Norwitzfc76d632006-01-10 06:03:13 +0000808- Patch #1400181, fix unicode string formatting to not use the locale.
809 This is how string objects work. u'%f' could use , instead of .
810 for the decimal point. Now both strings and unicode always use periods.
811
Neal Norwitz671b9e32006-01-09 07:07:12 +0000812- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
813 configure would break checking curses.h.
814
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000815- Bug #959576: The pwd module is now builtin. This allows Python to be
816 built on UNIX platforms without $HOME set.
817
Neal Norwitzc10978f2005-12-19 06:07:16 +0000818- Bug #1072182, fix some potential problems if characters are signed.
819
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000820- Bug #889500, fix line number on SyntaxWarning for global declarations.
821
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000822- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
823
Neal Norwitze7214a12005-12-18 05:03:17 +0000824- Support for converting hex strings to floats no longer works.
825 This was not portable. float('0x3') now raises a ValueError.
826
Barry Warsaw2a38a862005-12-18 01:27:35 +0000827- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000828 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000829 is now displayed in interactive prompt banner.
830
Georg Brandlfa166682005-12-17 21:45:17 +0000831- Implementation of PEP 341 - Unification of try/except and try/finally.
832 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000833 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000834
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000835- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
836 now encodes backslash correctly.
837
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000838- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
839
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000840- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000841 and long longs.
842
Neal Norwitz67715f02005-11-09 06:59:35 +0000843- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000844 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000845 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000846
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000847- Replaced most Unicode charmap codecs with new ones using the
848 new Unicode translate string feature in the builtin charmap
849 codec; the codecs were created from the mapping tables available
850 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
851 encodings now include a mapping for the Apple logo)
852
Tim Peterse3547fd2005-12-16 23:13:57 +0000853- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000854
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000855- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000856
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000857- A new AST parser implementation was completed. The abstract
858 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000859 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000860
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000861- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000862 The following code now raises a SyntaxError: foo(a = i for i in range(10))
863
Neal Norwitz708e51a2005-10-03 04:48:15 +0000864- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
865
Neal Norwitz11bd1192005-10-03 00:54:56 +0000866- SF Bug #887946: fix segfault when redirecting stdin from a directory.
867 Provide a warning when a directory is passed on the command line.
868
Neal Norwitz40d37812005-10-02 01:48:49 +0000869- Fix segfault with invalid coding.
870
871- SF bug #772896: unknown encoding results in MemoryError.
872
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000873- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000874 supported a __len__() method which evaluated to False when the iterator
875 was empty.
876
Guido van Rossum630db602005-09-20 18:49:54 +0000877- On 64-bit platforms, when __len__() returns a value that cannot be
878 represented as a C int, raise OverflowError.
879
Skip Montanarof8948ca2005-09-19 03:54:46 +0000880- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000881 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000882
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000883- SF bug #893549: parsing keyword arguments was broken with a few format
884 codes.
885
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000886- Changes donated by Elemental Security to make it work on AIX 5.3
887 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
888 bug #105470: test_pwd fails on 64bit system (Opteron).
889
Guido van Rossum539c6622005-09-14 17:49:54 +0000890- Changes donated by Elemental Security to make it work on HP-UX 11 on
891 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
892
Georg Brandl4550b8d2005-08-26 06:43:52 +0000893- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000894 (fixes bug #1119418).
895
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000896- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
897
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000898- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
899 exceptions that cause a function to exit.
900
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000901- The implementation of set() and frozenset() was revised to use its
902 own internal data structure. Memory consumption is reduced by 1/3
903 and there are modest speed-ups as well. The API is unchanged.
904
Tim Petersde7990b2005-07-17 23:45:23 +0000905- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
906
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000907- SF bug #1229429: PyObject_CallMethod failed to decrement some
908 reference counts in some error exit cases.
909
Tim Petersecc6e6a2005-07-10 22:30:55 +0000910- SF bug #1185883: Python's small-object memory allocator took over
911 a block managed by the platform C library whenever a realloc specified
912 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000913 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000914 portable way to copy data from the C-managed block into Python's
915 small-object space without risking a memory fault. Python's small-object
916 realloc now leaves such blocks under the control of the platform C
917 realloc.
918
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000919- SF bug #1232517: An overflow error was not detected properly when
920 attempting to convert a large float to an int in os.utime().
921
Raymond Hettinger3296e692005-06-29 23:29:56 +0000922- SF bug #1224347: hex longs now print with lowercase letters just
923 like their int counterparts.
924
Michael W. Hudson188d4362005-06-20 16:52:57 +0000925- SF bug #1163563: the original fix for bug #1010677 ("thread Module
926 Breaks PyGILState_Ensure()") broke badly in the case of multiple
927 interpreter states; back out that fix and do a better job (see
928 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
929 for a longer write-up of the problem).
930
Michael W. Hudsondf888462005-06-03 14:41:55 +0000931- SF patch #1180995: marshal now uses a binary format by default when
932 serializing floats.
933
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000934- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
935 the routines that promise to produce IEEE 754 binary representations
936 of floats now simply copy bytes around.
937
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000938- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
939 278.
940
Brett Cannonc3647ac2005-04-26 03:45:26 +0000941- patch #1109424: int, long, float, complex, and unicode now check for the
942 proper magic slot for type conversions when subclassed. Previously the
943 magic slot was ignored during conversion. Semantics now match the way
944 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000945 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000946 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000947 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000948
Barry Warsawc8d907c2005-04-19 23:43:40 +0000949- Descriptors defined in C with a PyGetSetDef structure, where the setter is
950 NULL, now raise an AttributeError when attempting to set or delete the
951 attribute. Previously a TypeError was raised, but this was inconsistent
952 with the equivalent pure-Python implementation.
953
Michael W. Hudson774479c2005-04-18 08:46:17 +0000954- It is now safe to call PyGILState_Release() before
955 PyEval_InitThreads() (note that if there is reason to believe there
956 are multiple threads around you still must call PyEval_InitThreads()
957 before using the Python API; this fix is for extension modules that
958 have no way of knowing if Python is multi-threaded yet).
959
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000960- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
961 disabled caused a crash.
962
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000963- Bug #1165306: instancemethod_new allowed the creation of a method
964 with im_class == im_self == NULL, which caused a crash when called.
965
Tim Petersecc6e6a2005-07-10 22:30:55 +0000966- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000967 fixes the crash seen in bug #1165761
968
Raymond Hettinger96229b12005-03-11 06:49:40 +0000969- Added two new builtins, any() and all().
970
Brett Cannon409d8f22005-03-05 06:47:57 +0000971- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000972 (e.g., ``class C(): pass`` is no longer a syntax error).
973 Patch #1176012 added support to the 'parser' module and 'compiler' package
974 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000975
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000976- Patch #1115086: Support PY_LONGLONG in structmember.
977
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000978- Bug #1155938: new style classes did not check that __init__() was
979 returning None.
980
Tim Petersecc6e6a2005-07-10 22:30:55 +0000981- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000982 ('\') with a specific error message.
983
Martin v. Löwisff232d72005-03-03 09:24:38 +0000984- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
985
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000986- Bug #1124295: the __name__ attribute of file objects was
987 inadvertently made inaccessible in restricted mode.
988
Tim Petersecc6e6a2005-07-10 22:30:55 +0000989- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000990 an ferror() call.
991
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000992- min() and max() now support key= arguments with the same meaning as in
993 list.sort().
994
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000995- The peephole optimizer now performs simple constant folding in expressions:
996 (2+3) --> (5).
997
Raymond Hettingera422c342005-01-11 03:03:27 +0000998- set and frozenset objects can now be marshalled. SF #1098985.
999
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001000- Bug #1077106: Poor argument checking could cause memory corruption
1001 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001002
Jeremy Hyltonab630502005-02-04 18:44:06 +00001003- The parser did not complain about future statements in illegal
1004 positions. It once again reports a syntax error if a future
1005 statement occurs after anything other than a doc string.
1006
Neil Schemenauercf52c072005-08-12 17:34:58 +00001007- Change the %s format specifier for str objects so that it returns a
1008 unicode instance if the argument is not an instance of basestring and
1009 calling __str__ on the argument returns a unicode instance.
1010
Tim Petersf4e69282006-02-27 17:15:31 +00001011- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1012 current thread state when the auto-GIL-state machinery knows about
1013 it (since the thread state is being deleted, continuing to remember it
1014 can't help, but can hurt if another thread happens to get created with
1015 the same thread id).
1016
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001017Extension Modules
1018-----------------
1019

Tim Petersc9d78aa2006-03-26 23:27:58 +00001032 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001033 util, whatsound, whrandom, zmod
1034
1035- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1036
1037- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001038 is deprecated. The undocumented re.engine variable no longer exists.
1039

1042
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001043- The unicodedata module was updated to the 4.1 version of the Unicode
1044 database. The 3.2 version is still available as unicodedata.db_3_2_0
1045 for applications that require this specific version (such as IDNA).
1046
Neal Norwitzb62c4332006-03-04 18:35:47 +00001047- The timing module is no longer built by default. It was deprecated
1048 in PEP 4 in Python 2.0 or earlier.
1049
Guido van Rossum1968ad32006-02-25 22:38:04 +00001050- Patch 1433928: Added a new type, defaultdict, to the collections module.
1051 This uses the new __missing__ hook behavior added to dict (see above).
1052
Georg Brandldbd83392006-02-20 09:42:33 +00001053- Bug #854823: socketmodule now builds on Sun platforms even when

1055
Georg Brandlf4f44152006-02-18 22:29:33 +00001056- Patch #1393157: os.startfile() now has an optional argument to specify

1063 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1064 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1065
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001066- Patch #1422385: The nis module now supports access to domains other
1067 than the system default domain.
1068
Martin v. Löwis14694662006-02-03 12:54:16 +00001069- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1070 are reported, the limit on path name lengths is removed, and stat reports
1071 WindowsError now (instead of OSError).
1072
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001073- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

1195 This allows islice() to work more readily with slices:
1196 islice(s.start, s.stop, s.step)
1197
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001198- datetime.datetime() now has a strptime class method which can be used to

1206
Nick Coghlan43832302006-04-23 17:04:07 +00001207- PEP 338: new module runpy defines a run_module function to support
1208 executing modules which provide access to source code or a code object
1209 via the PEP 302 import mechanisms.
1210
Anthony Baxter93f5b932006-04-03 08:05:07 +00001211- The email module's parsedate_tz function now sets the daylight savings

1219 in attribute values.
1220
Anthony Baxterc51ee692006-04-01 00:57:31 +00001221- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001222 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001223 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001224 module will not be built.
1225
Tim Petersc17976e2006-04-01 00:26:53 +00001226- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1227 aren't officially supported here, and trying to use them will probably
1228 raise an exception some day. But dicts have been allowed, and "mostly
1229 worked", so support for them won't go away without warning.
1230
Georg Brandl338ef7d2006-03-31 18:42:16 +00001231- Bug #1445068: getpass.getpass() can now be given an explicit stream

1243 to make it easier to monitor when daemon threads have completed
1244 processing all enqueued tasks. Patch #1455676.
1245
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001246- popen2.Popen objects now preserve the command in a .cmd attribute.

1249
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001250- email 4.0 package now integrated. This is largely the same as the email 3.0
1251 package that was included in Python 2.3, except that PEP 8 module names are
1252 now used (e.g. mail.message instead of email.Message). The MIME classes
1253 have been moved to a subpackage (e.g. email.mime.text instead of
1254 email.MIMEText). The old names are still supported for now. Several
1255 deprecated Message methods have been removed and lots of bugs have been
1256 fixed. More details can be found in the email package documentation.
1257
Walter Dörwald40108c92006-03-27 08:15:44 +00001258- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1259 (a subclass of tuple) that provides incremental decoders and encoders
1260 (a way to use stateful codecs without the stream API). Python functions
1261 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1262 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1263 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001264
Walter Dörwald067db482006-03-15 22:17:27 +00001265- Patch #1359365: Calling next() on a closed StringIO.String object raises
1266 a ValueError instead of a StopIteration now (like file and cString.String do).
1267 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1268 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001269

1276 grew an optional 'generation' argument.
1277
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001278- A library msilib to generate Windows Installer files, and a distutils

1343 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1344 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1345 Ronald L. Rivest offered this advice for Python:
1346
1347 "The consensus of researchers in this area (at least as
1348 expressed at the NIST Hash Function Workshop 10/31/05),
1349 is that SHA-256 is a good choice for the time being, but
1350 that research should continue, and other alternatives may
1351 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001352
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001353- Added a subset of Fredrik Lundh's ElementTree package. Available

1446 Bug #1224621.
1447
Raymond Hettinger68c04532005-06-10 11:05:19 +00001448- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001449 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001450 the generate_tokens() function now accepts a callable argument that
1451 terminates by raising StopIteration.
1452
Georg Brandl9166e1a2005-06-04 09:20:03 +00001453- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1454
Georg Brandl268e61c2005-06-03 14:28:50 +00001455- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1456 component of the path.
1457
Skip Montanaro174dd222005-05-14 20:54:16 +00001458- Patch #1120353: The xmlrpclib module provides better, more transparent,
1459 support for datetime.{datetime,date,time} objects. With use_datetime set
1460 to True, applications shouldn't have to fiddle with the DateTime wrapper
1461 class at all.
1462
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001463- distutils.commands.upload was added to support uploading distribution
1464 files to PyPI.
1465
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001466- distutils.commands.register now encodes the data as UTF-8 before posting
1467 them to PyPI.
1468
Raymond Hettinger267b8682005-03-27 10:47:39 +00001469- decimal operator and comparison methods now return NotImplemented
1470 instead of raising a TypeError when interacting with other types. This
1471 allows other classes to implement __radd__ style methods and have them
1472 work as expected.
1473
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001474- Bug #1163325: Decimal infinities failed to hash. Attempting to
1475 hash a NaN raised an InvalidOperation instead of a TypeError.
1476
Tim Petersecc6e6a2005-07-10 22:30:55 +00001477- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001478 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1479
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001480- Patch #1043890: Add extractall method to tarfile.
1481
Martin v. Löwisc72dd382005-03-04 13:50:17 +00001482- Patch #1075887: Don't require MSVC in distutils if there is nothing
1483 to build.
1484
Martin v. Löwis637431b2005-03-03 23:12:42 +00001485- Patch #1103407: Properly deal with tarfile iterators when untarring
1486 symbolic links on Windows.
1487
Tim Petersecc6e6a2005-07-10 22:30:55 +00001488- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001489 profile.py if available.
1490
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001491- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1492
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001493- Patch #1117454: Remove code to special-case cookies without values
1494 in LWPCookieJar.
1495
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001496- Patch #1117339: Add cookielib special name tests.
1497
Martin v. Löwise869eb12005-03-03 09:46:07 +00001498- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1499
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001500- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1501
Martin v. Löwisdf241532005-03-03 08:17:42 +00001502- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1503
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001504- Patch #1104111: Alter setup.py --help and --help-commands.
1505
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001506- Patch #1121234: Properly cleanup _exit and tkerror commands.
1507
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001508- Patch #1049151: xdrlib now unpacks booleans as True or False.
1509
Raymond Hettingerbab41432005-02-05 01:31:19 +00001510- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1511
Guido van Rossumd0641422005-02-03 15:01:24 +00001512- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1513 disables recursive traversal through instance attributes, which can
1514 be exploited in various ways.
1515
Tim Peterse3547fd2005-12-16 23:13:57 +00001516- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001517 flags on the HTTP listening socket.
1518
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001519- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1520 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1521
Tim Peterse3547fd2005-12-16 23:13:57 +00001522- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001523 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1524
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001525- Bug #1110478: Revert os.environ.update to do putenv again.
1526
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001527- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1528
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001529- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1530
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001531- Enhancements to the csv module:
1532
1533 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001534 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001535 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001536 + Dialect parameter parsing has been re-implemented to improve error
1537 reporting.
1538 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1539 dictates.
1540 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001541 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001542 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001543 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1544 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001545 + reader now allows \r characters to be quoted (previously it only allowed
1546 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001547 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001548 + Dialect classes passed to the module are no longer instantiated by
1549 the module before being parsed (the former validation scheme required
1550 this, but the mechanism was unreliable).
1551 + The dialect registry now contains instances of the internal
1552 C-coded dialect type, rather than references to python objects.
1553 + the internal c-coded dialect type is now immutable.
1554 + register_dialect now accepts the same keyword dialect specifications
1555 as the reader and writer, allowing the user to register dialects
1556 without first creating a dialect class.
1557 + a configurable limit to the size of parsed fields has been added -
1558 previously, an unmatched quote character could result in the entire
1559 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001560 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001561 the parser field size limit (returning the former limit). The initial
1562 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001563 + A line_num attribute has been added to the reader object, which tracks
1564 the number of lines read from the source iterator. This is not
1565 the same as the number of records returned, as records can span
1566 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001567 + reader and writer objects were not being registered with the cyclic-GC.
1568 This has been fixed.
1569
Brett Cannone6539c42005-01-08 02:43:53 +00001570- _DummyThread objects in the threading module now delete self.__block that is
1571 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1572 lock primitives tend to be limited in number and thus should not be wasted on
1573 a _DummyThread object. Fixes bug #1089632.
1574
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001575- The imghdr module now detects Exif files.
1576
Raymond Hettinger6065d322004-12-20 23:51:53 +00001577- StringIO.truncate() now correctly adjusts the size attribute.
1578 (Bug #951915).
1579
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001580- locale.py now uses an updated locale alias table (built using
1581 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1582 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001583 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001584
Raymond Hettinger3557f422004-12-07 12:02:02 +00001585- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1586
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001587- the pickle module no longer accepts the deprecated None option in the
1588 args tuple returned by __reduce__().
1589
Brett Cannon84667c02004-12-07 03:25:18 +00001590- optparse now optionally imports gettext. This allows its use in setup.py.
1591
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001592- the pickle module no longer uses the deprecated bin parameter.
1593
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001594- the shelve module no longer uses the deprecated binary parameter.
1595
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001596- the pstats module no longer uses the deprecated ignore() method.
1597
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001598- the filecmp module no longer uses the deprecated use_statcache argument.
1599
Raymond Hettinger664347b2004-12-04 21:21:53 +00001600- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1601 extended or overridden by subclasses. Formerly, the subclassed method would
1602 be ignored by the rest of the module. (Bug #1078905).
1603
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001604- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001605 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001606
Walter Dörwald36733692004-12-22 12:50:50 +00001607- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1608 once when a size argument is given. This prevents a buffer overflow in the
1609 tokenizer with very long source lines.
1610
Barry Warsaw538561e2006-01-01 21:48:54 +00001611- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1612 immediately after creating the object, without any intervening
1613 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001614
Skip Montanaro05885812005-01-16 20:48:27 +00001615- The reconvert.quote function can now emit triple-quoted strings. The
1616 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001617
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001618- ``UserString.MutableString`` now supports negative indices in
1619 ``__setitem__`` and ``__delitem__``
1620
Greg Ward40407942005-03-05 02:53:17 +00001621- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1622 correctly.
1623
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001624- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1625 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1626 character even if the user has passed a size parameter to get a proper
1627 line ending. Remove the special handling of a "\r\n" that has been split
1628 between two lines.
1629
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001630- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1631 about illegal code points. The codec now supports PEP 293 style error
1632 handlers.
1633
Walter Dörwald78a78b02005-09-01 12:04:29 +00001634- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001635 from the input stream, so that the output is a byte string in the correct
1636 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001637
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001638- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1639 considering it exactly like a '*'.
1640
Walter Dörwald007f8df2005-10-09 19:42:27 +00001641- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1642 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001643
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001644- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1645
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001646- Patch #1413711: Certain patterns of differences were making difflib
1647 touch the recursion limit.
1648
Walter Dörwald58917a62006-03-31 15:26:22 +00001649- Bug #947906: An object oriented interface has been added to the calendar
1650 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001651 called as a script (e.g. via ``python -mcalendar``). Localized month and
1652 weekday names can be ouput (even if an exotic encoding is used) using
1653 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001654
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001655Build
1656-----
1657
Neal Norwitz602d3392006-03-31 08:21:40 +00001658- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1659 by using -mieee gcc option.
1660
Martin v. Löwis86d66262006-02-17 08:40:11 +00001661- Patch #1432345: Make python compile on DragonFly.
1662
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001663- Build support for Win64-AMD64 was added.
1664
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001665- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1666
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001667- Patch #881820: look for openpty and forkpty also in libbsd.
1668
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001669- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1670 The zlib module is now builtin on Windows.
1671
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001672- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1673
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001674- Bug #1189330: configure did not correctly determine the necessary
1675 value of LINKCC if python was built with GCC 4.0.
1676
Trent Mick8321b422005-07-26 02:29:21 +00001677- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1678 vulnerability in zlib 1.2.1 and 1.2.2.
1679
Brett Cannon08cd5982005-04-24 22:26:38 +00001680- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1681 flags that change binary compatibility. Changes were also made to
1682 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001683 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001684
Bob Ippolitoed233462005-03-29 13:47:59 +00001685- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1686 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1687 no longer exists). This configure patch makes things right.
1688
Martin v. Löwise2713be2005-03-08 15:03:08 +00001689- Bug #1158607: Build with --disable-unicode again.
1690
Brett Cannon46d96232005-02-16 00:07:19 +00001691- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1692 defined. Discovered as a result of not being able to build on OS X.
1693
Brett Cannon516592f2004-12-07 00:42:59 +00001694- setup.py now uses the directories specified in LDFLAGS using the -L option
1695 and in CPPFLAGS using the -I option for adding library and include
1696 directories, respectively, for compiling extension modules against. This has
1697 led to the core being compiled using the values in CPPFLAGS. It also removes
1698 the need for the special-casing of both DarwinPorts and Fink for darwin since
1699 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1700 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1701 Fink, ``-I/opt/local/include`` for DarwinPorts).
1702
Brett Cannon43802422005-02-10 20:48:03 +00001703- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1704 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1705 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1706 Closes bug #1096244. Thanks Gregory Bond.

Tim Petersc9d78aa2006-03-26 23:27:58 +00001711- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1712 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1713 is obtained via the ``PyObject_`` family, it must be released via the
1714 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1715 always been officially true, but when Python's small-object allocator was
1716 introduced, an attempt was made to cater to a few extension modules
1717 discovered at the time that obtained memory via ``PyObject_New`` but
1718 released it via ``PyMem_DEL``. It's years later, and if such code still
1719 exists it will fail now (probably with segfaults, but calling wrong
1720 low-level memory management functions can yield many symptoms).

Raymond Hettingerbeb31012005-08-16 03:47:52 +00001722- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001726- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1727 mapping argument now. This string is used as a mapping table. Byte values
1728 greater than the length of the string and 0xFFFE are treated as undefined
1729 mappings.
