Neal Norwitza1f10902006-07-12 07:28:29 +00007What's New in Python 2.5 release candidate 1?
8=============================================
9
10*Release date: XX-AUG-2006*
11
12Core and builtins
13-----------------
14
Martin v. Löwisd22968a2006-07-24 11:54:53 +000015- Patch #1232023: Stop including current directory in search
16 path on Windows.
17
Neal Norwitze1fdb322006-07-21 05:32:28 +000018- Fix some potential crashes found with failmalloc.
19
Neal Norwitze7563102006-07-17 01:00:16 +000020- Fix warnings reported by Klocwork's static analysis tool.
21
Neal Norwitz84be93b2006-07-16 01:50:38 +000022- Bug #1512814, Fix incorrect lineno's when code within a function
23 had more than 255 blank lines.
24
Georg Brandl9dceedb2006-07-12 15:31:17 +000025- Patch #1521179: Python now accepts the standard options ``--help`` and
26 ``--version`` as well as ``/?`` on Windows.
27
Neal Norwitza1f10902006-07-12 07:28:29 +000028- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
29 again. Fixing this problem required changing the .pyc magic number.
30 This means that .pyc files generated before 2.5c1 will be regenerated.
31
Tim Peters112aad32006-07-19 00:03:19 +000032- Bug #1524317: Compiling Python ``--without-threads`` failed.
33 The Python core compiles again then, and, in a build without threads, the
34 new ``sys._current_frames()`` returns a dictionary with one entry,
35 mapping the faux "thread id" 0 to the current frame.
36

38-------
39
Greg Ward48fae7a2006-07-23 16:05:51 +000040- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
41
Martin v. Löwis426f4a12006-07-18 17:46:31 +000042- Patch #1524429: Use repr() instead of backticks in Tkinter again.
43
Brett Cannoncaebe222006-07-18 04:41:36 +000044- Bug #1520914: Change time.strftime() to accept a zero for any position in its
45 argument tuple. For arguments where zero is illegal, the value is forced to
46 the minimum value that is correct. This is to support an undocumented but
47 common way people used to fill in inconsequential information in the time
48 tuple pre-2.4.
49
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000050- Patch #1220874: Update the binhex module for Mach-O.
51
Barry Warsawb110bad2006-07-21 14:51:07 +000052- The email package has improved RFC 2231 support, specifically for
53 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
54 (name*0=<blah>) parameter continuations. This may change the types of
55 values returned from email.message.Message.get_param() and friends.
56 Specifically in some cases where non-encoded continuations were used,
57 get_param() used to return a 3-tuple of (None, None, string) whereas now it
58 will just return the string (since non-encoded continuations don't have
59 charset and language parts).
60
61 Also, whereas % values were decoded in all parameter continuations, they are
62 now only decoded in encoded parameter parts.

65-----------------
66
Martin v. Löwisbda0dde2006-07-24 10:26:33 +000067- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
68
Thomas Hellerce049a02006-07-14 17:51:14 +000069- Patch #1521817: Index range checking on ctypes arrays containing
70 exactly one element enabled again. This allows iterating over these
71 arrays, without the need to check the array size before.
72
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000073- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000074 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000075 /dev/null in certain cases; this is now fixed.
76
Thomas Heller47d7a062006-07-12 08:43:47 +000077- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
78 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000079
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000080- Because of a misspelled preprocessor symbol, ctypes was always
81 compiled without thread support; this is now fixed.

88Core and builtins
89-----------------
90
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000091- Bug #1441486: The literal representation of -(sys.maxint - 1)
92 again evaluates to a int object, not a long.
93
Neil Schemenauer0e07b602006-07-09 16:16:34 +000094- Bug #1501934: The scope of global variables that are locally assigned
95 using augmented assignment is now correctly determined.
96
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000097- Bug #927248: Recursive method-wrapper objects can now safely
98 be released.
99
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000100- Bug #1417699: Reject locale-specific decimal point in float()
101 and atof().
102
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000103- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
104 omit a default "error" argument for NULL pointer. This allows
105 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000106
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000107- Bug #1519018: 'as' is now validated properly in import statements.
108
Neal Norwitz28746ab2006-07-09 22:14:42 +0000109- On 64 bit systems, int literals that use less than 64 bits are
110 now ints rather than longs.
111
Neal Norwitzed657552006-07-10 00:04:44 +0000112- Bug #1512814, Fix incorrect lineno's when code at module scope
113 started after line 256.
114
Tim Peters32a83612006-07-10 21:08:24 +0000115- New function ``sys._current_frames()`` returns a dict mapping thread
116 id to topmost thread stack frame. This is for expert use, and is
117 especially useful for debugging application deadlocks. The functionality
118 was previously available in Fazal Majid's ``threadframe`` extension
119 module, but it wasn't possible to do this in a wholly threadsafe way from
120 an extension.
121
Georg Brandlad29e632006-06-21 17:45:17 +0000122Library
123-------
124
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000125- Patch #1519566: Update turtle demo, make begin_fill idempotent.
126
Tim Peters32a83612006-07-10 21:08:24 +0000127- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000128 environment variable to be set in order to the SDK environment
129 for finding the compiler, include files, etc.
130
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000131- Bug #1515998: Properly generate logical ids for files in bdist_msi.
132
Nick Coghlan2d792252006-07-06 13:47:18 +0000133- warnings.py now ignores ImportWarning by default
134
Thomas Woutersadd19112006-07-05 11:03:49 +0000135- string.Template() now correctly handles tuple-values. Previously,
136 multi-value tuples would raise an exception and single-value tuples would
137 be treated as the value they contain, instead.
138
Martin v. Löwisede77f52006-07-03 13:01:35 +0000139- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
140 even if some data are received.
141
Martin v. Löwis45482392006-07-03 12:28:58 +0000142- Bug #1267547: Put proper recursive setup.py call into the
143 spec file generated by bdist_rpm.
144
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000145- Bug #1514693: Update turtle's heading when switching between
146 degrees and radians.
147
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000148- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000149 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000150
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000151- Bug #1514703: Only setup canvas window in turtle when the canvas
152 is created.
153
Martin v. Löwis7596e832006-07-01 15:33:37 +0000154- Bug #1513223: .close() of a _socketobj now releases the underlying
155 socket again, which then gets closed as it becomes unreferenced.
156
Fred Drake10497c82006-06-29 02:57:48 +0000157- Bug #1504333: Make sgmllib support angle brackets in quoted
158 attribute values.
159
160- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
161 sgmllib ('[' and ']' were not accepted).
162
Georg Brandl1be63af2006-06-28 20:23:25 +0000163- Fix a bug in the turtle module's end_fill function.
164
Brett Cannon53ab5b72006-06-22 16:49:14 +0000165- Bug #1510580: The 'warnings' module improperly required that a Warning
166 category be either a types.ClassType and a subclass of Warning. The proper
167 check is just that it is a subclass with Warning as the documentation states.
168
Georg Brandlad29e632006-06-21 17:45:17 +0000169- The compiler module now correctly compiles the new try-except-finally
170 statement (bug #1509132).
171
Neal Norwitz60373cd2006-06-22 06:30:50 +0000172- The wsgiref package is now installed properly on Unix.
173
Vinay Sajip28e57612006-07-01 10:45:20 +0000174- A bug was fixed in logging.config.fileConfig() which caused a crash on
175 shutdown when fileConfig() was called multiple times.
176
Gerhard Häring762fbd32006-07-02 17:48:30 +0000177- The sqlite3 module did cut off data from the SQLite database at the first
178 null character before sending it to a custom converter. This has been fixed
179 now.
180
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000181Extension Modules
182-----------------
183
Tim Peters112aad32006-07-19 00:03:19 +0000184- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
185 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
186 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000187
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000188- Assigning None to pointer type fields in ctypes structures possible
189 overwrote the wrong fields, this is fixed now.
190
191- Fixed a segfault in _ctypes when ctypes.wintypes were imported
192 on non-Windows platforms.
193
194- Bug #1518190: The ctypes.c_void_p constructor now accepts any
195 integer or long, without range checking.
196
197- Patch #1517790: It is now possible to use custom objects in the ctypes
198 foreign function argtypes sequence as long as they provide a from_param
199 method, no longer is it required that the object is a ctypes type.
200
201- The '_ctypes' extension module now works when Python is configured
202 with the --without-threads option.
203
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000204- Bug #1513646: os.access on Windows now correctly determines write
205 access, again.
206
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000207- Bug #1512695: cPickle.loads could crash if it was interrupted with
208 a KeyboardInterrupt.
209
Neal Norwitza12aa882006-07-06 06:45:08 +0000210- Bug #1296433: parsing XML with a non-default encoding and
211 a CharacterDataHandler could crash the interpreter in pyexpat.
212
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000213- Patch #1516912: improve Modules support for OpenVMS.
214
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000215Build
216-----
217
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000218- Automate Windows build process for the Win64 SSL module.
219
Tim Peters32a83612006-07-10 21:08:24 +0000220- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000221 Previously, the slight difference could cause compilation errors of the
222 'zlib' module on systems with more than one version of zlib.
223
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000224- The MSI compileall step was fixed to also support a TARGETDIR
225 with spaces in it.
226
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000227- Bug #1517388: sqlite3.dll is now installed on Windows independent
228 of Tcl/Tk.
229
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000230- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000231 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000233Tests
234-----
235
236- Call os.waitpid() at the end of tests that spawn child processes in order
237 to minimize resources (zombies).
238
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000239Documentation
240-------------
241
Nick Coghlan2d792252006-07-06 13:47:18 +0000242- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
243 documentation for the warnings module.
244

Anthony Baxter51bcb682006-04-05 14:51:42 +0000253
254Core and builtins
255-----------------
256
Georg Brandla56b9152006-06-19 06:35:54 +0000257- Patch #1507676: Error messages returned by invalid abstract object operations
258 (such as iterating over an integer) have been improved and now include the
259 type of the offending object to help with debugging.
260
Brett Cannonea3912b2006-06-13 21:46:41 +0000261- Bug #992017: A classic class that defined a __coerce__() method that returned
262 its arguments swapped would infinitely recurse and segfault the interpreter.
263
Neal Norwitz909eb122006-06-12 02:13:21 +0000264- Fix the socket tests so they can be run concurrently.
265
Neal Norwitzb9845e72006-06-12 02:11:18 +0000266- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000267 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000268
Brett Cannon22565aa2006-06-09 22:31:23 +0000269- Bug #532646: object.__call__() will continue looking for the __call__
270 attribute on objects until one without one is found. This leads to recursion
271 when you take a class and set its __call__ attribute to an instance of the
272 class. Originally fixed for classic classes, but this fix is for new-style.
273 Removes the infinite_rec_3 crasher.
274
Georg Brandl24250812006-06-09 18:45:48 +0000275- The string and unicode methods startswith() and endswith() now accept
276 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
277
Brett Cannonde3b0522006-06-08 17:00:45 +0000278- Buffer objects, at the C level, never used the char buffer
279 implementation even when the char buffer for the wrapped object was
280 explicitly requested (originally returned the read or write buffer).
281 Now a TypeError is raised if the char buffer is not present but is
282 requested.
283
Georg Brandlddbaa662006-06-04 21:56:52 +0000284- Patch #1346214: Statements like "if 0: suite" are now again optimized
285 away like they were in Python 2.4.
286
Georg Brandlb7c8f542006-05-27 12:30:25 +0000287- Builtin exceptions are now full-blown new-style classes instead of
288 instances pretending to be classes, which speeds up exception handling
289 by about 80% in comparison to 2.5a2.
290
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000291- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
292 Unicode 4.1.
293
Georg Brandlf4ef1162006-05-26 18:03:31 +0000294- Patch #921466: sys.path_importer_cache is now used to cache valid and
295 invalid file paths for the built-in import machinery which leads to
296 fewer open calls on startup.
297
Tim Peters696cf432006-05-24 21:10:40 +0000298- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
299 of-2 bases. The largest speedup is for inputs with about 1000 decimal
300 digits. Conversion from non-power-of-2 bases remains quadratic-time in
301 the number of input digits (it was and remains linear-time for bases
302 2, 4, 8, 16 and 32).
303
Tim Petersb713ec22006-05-23 18:45:30 +0000304- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
305 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
306 an integer close to ``sys.maxint``. This was repaired by patch
307 #1335972, which also gives a nice speedup.
308
Richard Jonescebbefc2006-05-23 18:28:17 +0000309- Patch #1337051: reduced size of frame objects.
310
311- PyErr_NewException now accepts a tuple of base classes as its
312 "base" parameter.
313
Richard Jones7c88dcc2006-05-23 10:37:38 +0000314- Patch #876206: function call speedup by retaining allocated frame
315 objects.
316
Georg Brandl7b90e162006-05-18 07:01:27 +0000317- Bug #1462152: file() now checks more thoroughly for invalid mode
318 strings and removes a possible "U" before passing the mode to the
319 C library function.
320
Neal Norwitz1004a532006-05-15 07:17:23 +0000321- Patch #1488312, Fix memory alignment problem on SPARC in unicode
322
Neal Norwitz373f0a72006-05-15 07:04:36 +0000323- Bug #1487966: Fix SystemError with conditional expression in assignment
324
Martin v. Löwis879768d2006-05-11 13:28:43 +0000325- WindowsError now has two error code attributes: errno, which carries
326 the error values from errno.h, and winerror, which carries the error
327 values from winerror.h. Previous versions put the winerror.h values
328 (from GetLastError()) into the errno attribute.
329
Martin v. Löwis77736712006-05-04 05:51:03 +0000330- Patch #1475845: Raise IndentationError for unexpected indent.
331
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000332- Patch #1479181: split open() and file() from being aliases for each other.
333
Tim Peters44bd9862006-06-01 13:49:23 +0000334- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
335 methods were always silently ignored by dictionaries when comparing keys.
336 They are now passed through (except when using the C API function
337 ``PyDict_GetItem()``, whose semantics did not change).
338
339- Bug #1456209: In some obscure cases it was possible for a class with a
340 custom ``__eq__()`` method to confuse dict internals when class instances
341 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
342 No, you don't have any code that did this ;-)

348
349- Patch #1462338: Upgrade pyexpat to expat 2.0.0
350
Brett Cannon6ee7d012006-06-08 16:23:04 +0000351- Change binascii.hexlify to accept a read-only buffer instead of only a char
352 buffer and actually follow its documentation.
353
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000354- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
355
Nick Coghlanc649ec52006-05-29 12:43:05 +0000356- Patch #1478788 (modified version): The functional extension module has
357 been renamed to _functools and a functools Python wrapper module added.
358 This provides a home for additional function related utilities that are
359 not specifically about functional programming. See PEP 309.
360
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000361- Patch #1493701: performance enhancements for struct module.
362
Georg Brandl378d5922006-05-17 14:26:50 +0000363- Patch #1490224: time.altzone is now set correctly on Cygwin.
364
Georg Brandl8d3342b2006-05-16 07:38:27 +0000365- Patch #1435422: zlib's compress and decompress objects now have a
366 copy() method.
367
Andrew MacIntyre92913322006-06-13 15:04:24 +0000368- Patch #1454481: thread stack size is now tunable at runtime for thread
369 enabled builds on Windows and systems with Posix threads support.
370
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000371- On Win32, os.listdir now supports arbitrarily-long Unicode path names
372 (up to the system limit of 32K characters).
373
374- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
375 As a result, these functions now raise WindowsError instead of OSError.
376
Tim Peters7a822da2006-05-25 21:50:17 +0000377- ``time.clock()`` on Win64 should use the high-performance Windows
378 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
379 Windows platforms).
380
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000381- Calling Tk_Init twice is refused if the first call failed as that
382 may deadlock.
383
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000384- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
385 accept it without potentially using an uninitialized pointer.
386
387- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
388 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
389 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000390
Gregory P. Smith372b5832006-06-05 18:48:21 +0000391- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000392 [pybsddb project SF patch number 1466734]
393
Gregory P. Smith372b5832006-06-05 18:48:21 +0000394- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
395 parameter is supplied. [SF pybsddb bug #1477863]
396
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000397- bsddb: the __len__ method of a DB object has been fixed to return correct
398 results. It could previously incorrectly return 0 in some cases.
399 Fixes SF bug 1493322 (pybsddb bug 1184012).
400
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000401- bsddb: the bsddb.dbtables Modify method now raises the proper error and
402 aborts the db transaction safely when a modifier callback fails.
403 Fixes SF python patch/bug #1408584.
404
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000405- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000406 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000407 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
408 database calls that would previously deadlock. [SF python bug #775414]
409
Vinay Sajip28e57612006-07-01 10:45:20 +0000410- Patch #1446489: add support for the ZIP64 extensions to zipfile.

429 classes.
430
Georg Brandl83cc0d02006-06-14 08:50:03 +0000431- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
432 mime.types file for determining MIME types.
433
Georg Brandl2605ca82006-06-14 06:08:31 +0000434- Bug #1339007: Shelf objects now don't raise an exception in their
435 __del__ method when initialization failed.
436
Martin v. Löwisd8251432006-06-14 05:21:04 +0000437- Patch #1455898: The MBCS codec now supports the incremental mode for
438 double-byte encodings.
439
Tim Peters43898b42006-06-14 04:09:25 +0000440- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
441 guarantee that adjacent triples in the return list always describe
442 non-adjacent blocks. Previously, a pair of matching blocks could end
443 up being described by multiple adjacent triples that formed a partition
444 of the matching pair.
445
Greg Ward0e0c9f42006-06-11 16:24:11 +0000446- Bug #1498146: fix optparse to handle Unicode strings in option help,
447 description, and epilog.
448
Greg Wardd1c797e2006-06-11 14:42:41 +0000449- Bug #1366250: minor optparse documentation error.
450
Greg Ward7f547402006-06-11 00:40:49 +0000451- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
452 clarify docs.
453
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000454- The wsgiref package has been added to the standard library.
455
Nick Coghlan676725d2006-06-08 13:54:49 +0000456- The functions update_wrapper() and wraps() have been added to the functools
457 module. These make it easier to copy relevant metadata from the original
458 function when writing wrapper functions.
459
Tim Petersd6a9eef2006-06-05 01:48:21 +0000460- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
461 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000462
Martin v. Löwis3f767792006-06-04 19:36:28 +0000463- Patch #1359618: Speed up charmap encoder by using a trie structure
464 for lookup.
465
Tim Petersd609b1a2006-06-02 23:22:51 +0000466- The functions in the ``pprint`` module now sort dictionaries by key
467 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
468 if and only if its display required more than one line, although that
469 wasn't documented. The new behavior increases predictability; e.g.,
470 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
471
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000472- Patch #1497027: try HTTP digest auth before basic auth in urllib2
473 (thanks for J. J. Lee).
474
Georg Brandl2b330372006-05-28 20:23:12 +0000475- Patch #1496206: improve urllib2 handling of passwords with respect to
476 default HTTP and HTTPS ports.
477
George Yoshidaf3c65de2006-05-28 16:39:09 +0000478- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
479
Bob Ippolito7298f272006-05-23 18:43:47 +0000480- Patch #1281707: speed up gzip.readline.
481
Georg Brandlb89316f2006-05-17 15:51:16 +0000482- Patch #1180296: Two new functions were added to the locale module:
483 format_string() to get the effect of "format % items" but locale-aware,
484 and currency() to format a monetary number with currency sign.
485
Georg Brandle3a25832006-05-17 14:56:04 +0000486- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
487 and several features added, such as speed and geometry control.
488
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000489- Patch #1488881: add support for external file objects in bz2 compressed
490 tarfiles.
491
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000492- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
493 stdout arguments, making it possible to redirect input and output
494 for remote debugging.
495
496- Patch #1484695: Update the tarfile module to version 0.8. This fixes
497 a couple of issues, notably handling of long file names using the
498 GNU LONGNAME extension.
499
500- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
501 new flag when ``name`` is already the name of an option flag.
502
503- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
504 package.
505
506- Patch #1472854: make the rlcompleter.Completer class usable on non-
507 UNIX platforms.
508

544
545*Release date: 27-APR-2006*
546
547Core and builtins
548-----------------
549
Thomas Heller1b046642006-04-18 18:51:06 +0000550- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
551 by converting these apis from macros into exported functions again:
552
553 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
554 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
555 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
556 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
557 PyRun_String Py_CompileString
558
Martin v. Löwis45294a92006-04-18 06:24:08 +0000559- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
560
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000561- All uses of PyStructSequence_InitType have been changed to initialize
562 the type objects only once, even if the interpreter is initialized
563 multiple times.
564
Neal Norwitz61546162006-04-14 05:20:28 +0000565- Bug #1454485, array.array('u') could crash the interpreter. This was
566 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
567 to unicode when it didn't make sense. 'u#' now requires a unicode string.
568
569- Py_UNICODE is unsigned. It was always documented as unsigned, but
570 due to a bug had a signed value in previous versions.
571
Tim Peters3a5e8b12006-04-11 01:44:07 +0000572- Patch #837242: ``id()`` of any Python object always gives a positive
573 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
574 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000575 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000576 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000577
Tim Peters3a5e8b12006-04-11 01:44:07 +0000578 def __hash__(self):
579 return id(self) # WRONG
580
581 because a hash result must be a (short) Python int but it was always
582 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000583 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000584 was always usable as a hash value before this patch. That's no longer
585 necessarily so.
586
587- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000588 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000589 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000590 #1454844)
591
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000592- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
593 involving generators that have paused outside of any ``try`` or ``with``
594 blocks. (In 2.5a1, a paused generator that was part of a reference
595 cycle could not be garbage collected, regardless of whether it was
596 paused in a ``try`` or ``with`` block.)

610 the cachesize parameter.
611
612- Bug #1149413: bsddb.*open() no longer raises an exception when using
613 a temporary db (file=None) with the 'n' flag to truncate on open.
614
615- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
616 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000617
Armin Rigoa9017c32006-04-19 11:50:27 +0000618- Patch #1062014: AF_UNIX sockets under Linux have a special

622-------
623
Peter Astrand7d1d4362006-07-14 14:04:45 +0000624- Bug #1223937: subprocess.CalledProcessError reports the exit status
625 of the process using the returncode attribute, instead of
626 abusing errno.
627
Tim Peters711bf302006-04-25 03:31:36 +0000628- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
629 a doctest to be skipped (the code is not run, and the expected output
630 or exception is ignored).
631
Nick Coghlanda2268f2006-04-24 04:37:15 +0000632- Fixed contextlib.nested to cope with exceptions being raised and
633 caught inside exit handlers.

Greg Wardab05edc2006-04-23 03:47:58 +0000635- Updated optparse module to Optik 1.5.1 (allow numeric constants in
636 hex, octal, or binary; add ``append_const`` action; keep going if
637 gettext cannot be imported; added ``OptionParser.destroy()`` method;
638 added ``epilog`` for better help generation).
639
Tim Peters21fbd572006-04-21 21:18:10 +0000640- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
641 called from a thread spawned as a side effect of importing a module.
642
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000643- The pydoc module now supports documenting packages contained in
644 .zip or .egg files.
645
646- The pkgutil module now has several new utility functions, such
647 as ``walk_packages()`` to support working with packages that are either
648 in the filesystem or zip files.
649
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000650- The mailbox module can now modify and delete messages from
651 mailboxes, in addition to simply reading them. Thanks to Gregory
652 K. Johnson for writing the code, and to the 2005 Google Summer of
653 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000654
Tim Petersc7605f22006-04-17 21:12:33 +0000655- The ``__del__`` method of class ``local`` in module ``_threading_local``
656 returned before accomplishing any of its intended cleanup.
657

663
Anthony Baxtere29002c2006-04-12 12:07:31 +0000664- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
665 Windows. Bug #1469163.
666
Phillip J. Eby47032112006-04-11 01:07:43 +0000667- The warnings, linecache, inspect, traceback, site, and doctest modules
668 were updated to work correctly with modules imported from zipfiles or
669 via other PEP 302 __loader__ objects.
670
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000671- Patch #1467770: Reduce usage of subprocess._active to processes which
672 the application hasn't waited on.
673
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000674- Patch #1462222: Fix Tix.Grid.
675
Neal Norwitza31bf182006-04-09 03:35:43 +0000676- Fix exception when doing glob.glob('anything*/')
677
Skip Montanaro262fb922006-04-21 02:31:07 +0000678- The pstats.Stats class accepts an optional stream keyword argument to
679 direct output to an alternate file-like object.
680
Anthony Baxter51bcb682006-04-05 14:51:42 +0000681Build
682-----
683
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000684- The Makefile now has a reindent target, which runs reindent.py on
685 the library.
686
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000687- Patch #1470875: Building Python with MS Free Compiler
688
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000689- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000690
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000691- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
692 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000693 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000694 CXX from --with-cxx-main, see description in README.
695
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000696- Patch #1429775: Link extension modules with the shared libpython.
697
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000698- Fixed a libffi build problem on MIPS systems.
699
Tim Peters8931ff12006-05-13 23:28:20 +0000700- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
701 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
702 and "%zu" for unsigned integers of type ``size_t``.
703
Anthony Baxter51bcb682006-04-05 14:51:42 +0000704Tests
705-----
706
Nick Coghlanda2268f2006-04-24 04:37:15 +0000707- test_contextlib now checks contextlib.nested can cope with exceptions
708 being raised and caught inside exit handlers.
709
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000710- test_cmd_line now checks operation of the -m and -c command switches
711
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000712- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
713 it separately and by hand. It also wasn't cleaning up its changes to
714 the current Decimal context.
715
Thomas Woutersabd08882006-04-26 15:53:30 +0000716- regrtest.py now has a -M option to run tests that test the new limits of
717 containers, on 64-bit architectures. Running these tests is only sensible
718 on 64-bit machines with more than two gigabytes of memory. The argument
719 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000727Documentation
728-------------
729
Tim Petersb06d28c2006-05-12 01:57:59 +0000730- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
731
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000732- PEP 343: Added Context Types section to the library reference
733 and attempted to bring other PEP 343 related documentation into
734 line with the implementation and/or python-dev discussions.
735
Tim Peters8dc73d22006-04-24 02:03:16 +0000736- Bug #1337990: clarified that ``doctest`` does not support examples
737 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000740What's New in Python 2.5 alpha 1?
741=================================
742
Anthony Baxterebed3f62006-04-03 15:03:44 +0000743*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000744
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000745Core and builtins
746-----------------
747
Nick Coghlan43832302006-04-23 17:04:07 +0000748- PEP 338: -m command line switch now delegates to runpy.run_module
749 allowing it to support modules in packages and zipfiles
750
Martin v. Löwisc661b882006-04-20 04:54:23 +0000751- On Windows, .DLL is not an accepted file name extension for
752 extension modules anymore; extensions are only found if they
753 end in .PYD.
754
Martin v. Löwisea62d252006-04-03 10:56:49 +0000755- Bug #1421664: sys.stderr.encoding is now set to the same value as
756 sys.stdout.encoding.
757
Neal Norwitz92e212f2006-04-03 04:48:37 +0000758- __import__ accepts keyword arguments.
759
Georg Brandlccadf842006-03-31 18:54:53 +0000760- Patch #1460496: round() now accepts keyword arguments.
761
Anthony Baxter262c00a2006-03-30 10:53:17 +0000762- Fixed bug #1459029 - unicode reprs were double-escaped.
763
Hye-Shik Changd478f342006-03-23 12:32:36 +0000764- Patch #1396919: The system scope threads are reenabled on FreeBSD
765 5.4 and later versions.
766
Neal Norwitze98ccf62006-03-23 05:39:47 +0000767- Bug #1115379: Compiling a Unicode string with an encoding declaration
768 now gives a SyntaxError.
769
Georg Brandlabd1ff82006-03-18 07:59:59 +0000770- Previously, Python code had no easy way to access the contents of a
771 cell object. Now, a ``cell_contents`` attribute has been added
772 (closes patch #1170323).
773
Tim Peterscf79aac2006-03-16 01:14:46 +0000774- Patch #1123430: Python's small-object allocator now returns an arena to
775 the system ``free()`` when all memory within an arena becomes unused
776 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
777 freed. Some applications will see a drop in virtual memory size now,
778 especially long-running applications that, from time to time, temporarily
779 use a large number of small objects. Note that when Python returns an
780 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000781 platform C library will in turn return that memory to the operating system.
782 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000783 appears to be effective at least on Microsoft C and gcc-based systems.
784 Thanks to Evan Jones for hard work and patience.
785
Georg Brandl533ff6f2006-03-08 18:09:27 +0000786- Patch #1434038: property() now uses the getter's docstring if there is
787 no "doc" argument given. This makes it possible to legitimately use
788 property() as a decorator to produce a read-only property.
789
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000790- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
791 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
792 of requiring an int or long in slicing and a few other contexts, enabling
793 other objects (e.g. Numeric Python's integers) to be used as slice indices.
794
Neal Norwitz995acdf2006-03-07 05:01:00 +0000795- Fixed various bugs reported by Coverity's Prevent tool.
796
Brett Cannonbf364092006-03-01 04:25:17 +0000797- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
798 new exception base class, BaseException, which has a new message attribute.
799 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
800 Raising a string exception now raises a DeprecationWarning.
801
Thomas Woutersfb609f42006-02-28 16:37:25 +0000802- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
803 explicitly relative, using 'from .module import name' to mean 'from the same
804 package as this module is in. Imports without dots still default to the
805 old relative-then-absolute, unless 'from __future__ import
806 absolute_import' is used.
807
Brett Cannona7446e32006-02-27 23:39:10 +0000808- Properly check if 'warnings' raises an exception (usually when a filter set
809 to "error" is triggered) when raising a warning for raising string
810 exceptions.
811
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000812- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000813 The name was removed from Include/code.h.
814
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000815- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000816
Guido van Rossum1968ad32006-02-25 22:38:04 +0000817- Patch 1433928:
818 - The copy module now "copies" function objects (as atomic objects).
819 - dict.__getitem__ now looks for a __missing__ hook before raising
820 KeyError.
821
Tim Peters84ef21c2006-02-28 20:39:06 +0000822- PEP 343: with statement implemented. Needs ``from __future__ import
823 with_statement``. Use of 'with' as a variable will generate a warning.
824 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000825 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000826 The following objects have __context__ methods:
827 - The built-in file type.
828 - The thread.LockType type.
829 - The following types defined by the threading module:
830 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
831 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000832
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000833- Fix the encodings package codec search function to only search
834 inside its own package. Fixes problem reported in patch #1433198.
835
836 Note: Codec packages should implement and register their own
837 codec search function. PEP 100 has the details.
838
Tim Peters9ea89d22006-06-04 03:26:02 +0000839- PEP 353: Using ``Py_ssize_t`` as the index type.
840
841- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
842 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
843 now allow Python to make use of memory blocks exceeding 2**32 bytes for
844 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
845 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000846
Neal Norwitzfc76d632006-01-10 06:03:13 +0000847- Patch #1400181, fix unicode string formatting to not use the locale.
848 This is how string objects work. u'%f' could use , instead of .
849 for the decimal point. Now both strings and unicode always use periods.
850
Neal Norwitz671b9e32006-01-09 07:07:12 +0000851- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
852 configure would break checking curses.h.
853
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000854- Bug #959576: The pwd module is now builtin. This allows Python to be
855 built on UNIX platforms without $HOME set.
856
Neal Norwitzc10978f2005-12-19 06:07:16 +0000857- Bug #1072182, fix some potential problems if characters are signed.
858
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000859- Bug #889500, fix line number on SyntaxWarning for global declarations.
860
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000861- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
862
Neal Norwitze7214a12005-12-18 05:03:17 +0000863- Support for converting hex strings to floats no longer works.
864 This was not portable. float('0x3') now raises a ValueError.
865
Barry Warsaw2a38a862005-12-18 01:27:35 +0000866- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000867 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000868 is now displayed in interactive prompt banner.
869
Georg Brandlfa166682005-12-17 21:45:17 +0000870- Implementation of PEP 341 - Unification of try/except and try/finally.
871 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000872 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000873
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000874- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
875 now encodes backslash correctly.
876
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000877- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
878
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000879- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000880 and long longs.
881
Neal Norwitz67715f02005-11-09 06:59:35 +0000882- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000883 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000884 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000885
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000886- Replaced most Unicode charmap codecs with new ones using the
887 new Unicode translate string feature in the builtin charmap
888 codec; the codecs were created from the mapping tables available
889 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
890 encodings now include a mapping for the Apple logo)
891
Tim Peterse3547fd2005-12-16 23:13:57 +0000892- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000893
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000894- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000895
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000896- A new AST parser implementation was completed. The abstract
897 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000898 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000899
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000900- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000901 The following code now raises a SyntaxError: foo(a = i for i in range(10))
902
Neal Norwitz708e51a2005-10-03 04:48:15 +0000903- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
904
Neal Norwitz11bd1192005-10-03 00:54:56 +0000905- SF Bug #887946: fix segfault when redirecting stdin from a directory.
906 Provide a warning when a directory is passed on the command line.
907
Neal Norwitz40d37812005-10-02 01:48:49 +0000908- Fix segfault with invalid coding.
909
910- SF bug #772896: unknown encoding results in MemoryError.
911
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000912- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000913 supported a __len__() method which evaluated to False when the iterator
914 was empty.
915
Guido van Rossum630db602005-09-20 18:49:54 +0000916- On 64-bit platforms, when __len__() returns a value that cannot be
917 represented as a C int, raise OverflowError.

Skip Montanarof8948ca2005-09-19 03:54:46 +0000919- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000920 present).

Georg Brandl80bbf3f2005-09-14 19:38:29 +0000922- SF bug #893549: parsing keyword arguments was broken with a few format
923 codes.
924
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000925- Changes donated by Elemental Security to make it work on AIX 5.3
926 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
927 bug #105470: test_pwd fails on 64bit system (Opteron).
928
Guido van Rossum539c6622005-09-14 17:49:54 +0000929- Changes donated by Elemental Security to make it work on HP-UX 11 on
930 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
931
Georg Brandl4550b8d2005-08-26 06:43:52 +0000932- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000933 (fixes bug #1119418).
934
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000935- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
936
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000937- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
938 exceptions that cause a function to exit.
939
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000940- The implementation of set() and frozenset() was revised to use its
941 own internal data structure. Memory consumption is reduced by 1/3
942 and there are modest speed-ups as well. The API is unchanged.
943
Tim Petersde7990b2005-07-17 23:45:23 +0000944- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
945
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000946- SF bug #1229429: PyObject_CallMethod failed to decrement some
947 reference counts in some error exit cases.
948
Tim Petersecc6e6a2005-07-10 22:30:55 +0000949- SF bug #1185883: Python's small-object memory allocator took over
950 a block managed by the platform C library whenever a realloc specified
951 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000952 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000953 portable way to copy data from the C-managed block into Python's
954 small-object space without risking a memory fault. Python's small-object
955 realloc now leaves such blocks under the control of the platform C
956 realloc.
957
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000958- SF bug #1232517: An overflow error was not detected properly when
959 attempting to convert a large float to an int in os.utime().
960
Raymond Hettinger3296e692005-06-29 23:29:56 +0000961- SF bug #1224347: hex longs now print with lowercase letters just
962 like their int counterparts.
963
Michael W. Hudson188d4362005-06-20 16:52:57 +0000964- SF bug #1163563: the original fix for bug #1010677 ("thread Module
965 Breaks PyGILState_Ensure()") broke badly in the case of multiple
966 interpreter states; back out that fix and do a better job (see
967 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
968 for a longer write-up of the problem).
969
Michael W. Hudsondf888462005-06-03 14:41:55 +0000970- SF patch #1180995: marshal now uses a binary format by default when
971 serializing floats.
972
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000973- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
974 the routines that promise to produce IEEE 754 binary representations
975 of floats now simply copy bytes around.
976
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000977- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
978 278.
979
Brett Cannonc3647ac2005-04-26 03:45:26 +0000980- patch #1109424: int, long, float, complex, and unicode now check for the
981 proper magic slot for type conversions when subclassed. Previously the
982 magic slot was ignored during conversion. Semantics now match the way
983 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000984 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000985 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000986 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000987
Barry Warsawc8d907c2005-04-19 23:43:40 +0000988- Descriptors defined in C with a PyGetSetDef structure, where the setter is
989 NULL, now raise an AttributeError when attempting to set or delete the
990 attribute. Previously a TypeError was raised, but this was inconsistent
991 with the equivalent pure-Python implementation.
992
Michael W. Hudson774479c2005-04-18 08:46:17 +0000993- It is now safe to call PyGILState_Release() before
994 PyEval_InitThreads() (note that if there is reason to believe there
995 are multiple threads around you still must call PyEval_InitThreads()
996 before using the Python API; this fix is for extension modules that
997 have no way of knowing if Python is multi-threaded yet).
998
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000999- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1000 disabled caused a crash.
1001
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001002- Bug #1165306: instancemethod_new allowed the creation of a method
1003 with im_class == im_self == NULL, which caused a crash when called.
1004
Tim Petersecc6e6a2005-07-10 22:30:55 +00001005- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001006 fixes the crash seen in bug #1165761
1007
Raymond Hettinger96229b12005-03-11 06:49:40 +00001008- Added two new builtins, any() and all().
1009
Brett Cannon409d8f22005-03-05 06:47:57 +00001010- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001011 (e.g., ``class C(): pass`` is no longer a syntax error).
1012 Patch #1176012 added support to the 'parser' module and 'compiler' package
1013 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001014
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001015- Patch #1115086: Support PY_LONGLONG in structmember.
1016
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001017- Bug #1155938: new style classes did not check that __init__() was
1018 returning None.
1019
Tim Petersecc6e6a2005-07-10 22:30:55 +00001020- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001021 ('\') with a specific error message.
1022
Martin v. Löwisff232d72005-03-03 09:24:38 +00001023- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1024
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001025- Bug #1124295: the __name__ attribute of file objects was
1026 inadvertently made inaccessible in restricted mode.
1027
Tim Petersecc6e6a2005-07-10 22:30:55 +00001028- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001029 an ferror() call.
1030
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001031- min() and max() now support key= arguments with the same meaning as in
1032 list.sort().
1033
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001034- The peephole optimizer now performs simple constant folding in expressions:
1035 (2+3) --> (5).
1036
Raymond Hettingera422c342005-01-11 03:03:27 +00001037- set and frozenset objects can now be marshalled. SF #1098985.
1038
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001039- Bug #1077106: Poor argument checking could cause memory corruption
1040 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001041
Jeremy Hyltonab630502005-02-04 18:44:06 +00001042- The parser did not complain about future statements in illegal
1043 positions. It once again reports a syntax error if a future
1044 statement occurs after anything other than a doc string.
1045
Neil Schemenauercf52c072005-08-12 17:34:58 +00001046- Change the %s format specifier for str objects so that it returns a
1047 unicode instance if the argument is not an instance of basestring and
1048 calling __str__ on the argument returns a unicode instance.
1049
Tim Petersf4e69282006-02-27 17:15:31 +00001050- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1051 current thread state when the auto-GIL-state machinery knows about
1052 it (since the thread state is being deleted, continuing to remember it
1053 can't help, but can hurt if another thread happens to get created with
1054 the same thread id).
1055
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001056Extension Modules

1073
1074- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1075
1076- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001077 is deprecated. The undocumented re.engine variable no longer exists.
1078

1081
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001082- The unicodedata module was updated to the 4.1 version of the Unicode
1083 database. The 3.2 version is still available as unicodedata.db_3_2_0
1084 for applications that require this specific version (such as IDNA).
1085
Neal Norwitzb62c4332006-03-04 18:35:47 +00001086- The timing module is no longer built by default. It was deprecated
1087 in PEP 4 in Python 2.0 or earlier.
1088
Guido van Rossum1968ad32006-02-25 22:38:04 +00001089- Patch 1433928: Added a new type, defaultdict, to the collections module.
1090 This uses the new __missing__ hook behavior added to dict (see above).
1091
Georg Brandldbd83392006-02-20 09:42:33 +00001092- Bug #854823: socketmodule now builds on Sun platforms even when

1094
Georg Brandlf4f44152006-02-18 22:29:33 +00001095- Patch #1393157: os.startfile() now has an optional argument to specify
1096 a "command verb" to invoke on the file.
1097

1102 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1103 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1104
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001105- Patch #1422385: The nis module now supports access to domains other
1106 than the system default domain.
1107
Martin v. Löwis14694662006-02-03 12:54:16 +00001108- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1109 are reported, the limit on path name lengths is removed, and stat reports
1110 WindowsError now (instead of OSError).
1111
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001112- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001246- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1247 been renamed to have only a single underscore prefix. This was done to
1248 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001249
Nick Coghlan43832302006-04-23 17:04:07 +00001250- PEP 338: new module runpy defines a run_module function to support
1251 executing modules which provide access to source code or a code object
1252 via the PEP 302 import mechanisms.
1253
Anthony Baxter93f5b932006-04-03 08:05:07 +00001254- The email module's parsedate_tz function now sets the daylight savings

1262 in attribute values.
1263
Anthony Baxterc51ee692006-04-01 00:57:31 +00001264- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001265 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001266 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001267 module will not be built.
1268
Tim Petersc17976e2006-04-01 00:26:53 +00001269- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1270 aren't officially supported here, and trying to use them will probably
1271 raise an exception some day. But dicts have been allowed, and "mostly
1272 worked", so support for them won't go away without warning.
1273
Georg Brandl338ef7d2006-03-31 18:42:16 +00001274- Bug #1445068: getpass.getpass() can now be given an explicit stream
1275 argument to specify where to write the prompt.
1276
Georg Brandl22ec80b2006-03-31 18:25:44 +00001277- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1286 to make it easier to monitor when daemon threads have completed
1287 processing all enqueued tasks. Patch #1455676.
1288

1292
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001293- email 4.0 package now integrated. This is largely the same as the email 3.0
1294 package that was included in Python 2.3, except that PEP 8 module names are
1295 now used (e.g. mail.message instead of email.Message). The MIME classes
1296 have been moved to a subpackage (e.g. email.mime.text instead of
1297 email.MIMEText). The old names are still supported for now. Several
1298 deprecated Message methods have been removed and lots of bugs have been
1299 fixed. More details can be found in the email package documentation.
1300
Walter Dörwald40108c92006-03-27 08:15:44 +00001301- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1302 (a subclass of tuple) that provides incremental decoders and encoders
1303 (a way to use stateful codecs without the stream API). Python functions
1304 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1305 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1306 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001307
Walter Dörwald067db482006-03-15 22:17:27 +00001308- Patch #1359365: Calling next() on a closed StringIO.String object raises
1309 a ValueError instead of a StopIteration now (like file and cString.String do).
1310 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1311 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001312
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001313- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00001385 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1386 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1387 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1388 Ronald L. Rivest offered this advice for Python:
1389
1390 "The consensus of researchers in this area (at least as
1391 expressed at the NIST Hash Function Workshop 10/31/05),
1392 is that SHA-256 is a good choice for the time being, but
1393 that research should continue, and other alternatives may
1394 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001395
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001396- Added a subset of Fredrik Lundh's ElementTree package. Available

1471
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001472- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1473 to W3C name (404 -> 'Not Found'). RFE #1216944.
1474
Georg Brandl9e43acf2005-07-04 17:16:07 +00001475- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1476 as this can cause problems with apps closing all file descriptors.
1477
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001478- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001479 it can be missing in embedded interpreters

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001488- The tokenize module now detects and reports indentation errors.
1489 Bug #1224621.
1490
Raymond Hettinger68c04532005-06-10 11:05:19 +00001491- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001492 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001493 the generate_tokens() function now accepts a callable argument that
1494 terminates by raising StopIteration.
1495
Georg Brandl9166e1a2005-06-04 09:20:03 +00001496- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1503 to True, applications shouldn't have to fiddle with the DateTime wrapper
1504 class at all.
1505
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001506- distutils.commands.upload was added to support uploading distribution

1510 them to PyPI.
1511
Raymond Hettinger267b8682005-03-27 10:47:39 +00001512- decimal operator and comparison methods now return NotImplemented
1513 instead of raising a TypeError when interacting with other types. This
1514 allows other classes to implement __radd__ style methods and have them
1515 work as expected.
1516
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001517- Bug #1163325: Decimal infinities failed to hash. Attempting to
1518 hash a NaN raised an InvalidOperation instead of a TypeError.
1519
Tim Petersecc6e6a2005-07-10 22:30:55 +00001520- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1554
Guido van Rossumd0641422005-02-03 15:01:24 +00001555- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1556 disables recursive traversal through instance attributes, which can
1557 be exploited in various ways.
1558
Tim Peterse3547fd2005-12-16 23:13:57 +00001559- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001560 flags on the HTTP listening socket.
1561
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001562- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1563 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1564
Tim Peterse3547fd2005-12-16 23:13:57 +00001565- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001566 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1567
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001568- Bug #1110478: Revert os.environ.update to do putenv again.
1569
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001570- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1571
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001572- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1573
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001574- Enhancements to the csv module:
1575
1576 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001577 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001578 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001579 + Dialect parameter parsing has been re-implemented to improve error
1580 reporting.
1581 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1582 dictates.
1583 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001584 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001585 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001586 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1587 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001588 + reader now allows \r characters to be quoted (previously it only allowed
1589 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001590 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001591 + Dialect classes passed to the module are no longer instantiated by
1592 the module before being parsed (the former validation scheme required
1593 this, but the mechanism was unreliable).
1594 + The dialect registry now contains instances of the internal
1595 C-coded dialect type, rather than references to python objects.
1596 + the internal c-coded dialect type is now immutable.
1597 + register_dialect now accepts the same keyword dialect specifications
1598 as the reader and writer, allowing the user to register dialects
1599 without first creating a dialect class.
1600 + a configurable limit to the size of parsed fields has been added -
1601 previously, an unmatched quote character could result in the entire
1602 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001603 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001604 the parser field size limit (returning the former limit). The initial
1605 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001606 + A line_num attribute has been added to the reader object, which tracks
1607 the number of lines read from the source iterator. This is not
1608 the same as the number of records returned, as records can span
1609 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001610 + reader and writer objects were not being registered with the cyclic-GC.
1611 This has been fixed.
1612
Brett Cannone6539c42005-01-08 02:43:53 +00001613- _DummyThread objects in the threading module now delete self.__block that is
1614 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1615 lock primitives tend to be limited in number and thus should not be wasted on
1616 a _DummyThread object. Fixes bug #1089632.
1617
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001618- The imghdr module now detects Exif files.
1619
Raymond Hettinger6065d322004-12-20 23:51:53 +00001620- StringIO.truncate() now correctly adjusts the size attribute.
1621 (Bug #951915).
1622
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001623- locale.py now uses an updated locale alias table (built using
1624 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1625 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001626 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001627
Raymond Hettinger3557f422004-12-07 12:02:02 +00001628- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1629
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001630- the pickle module no longer accepts the deprecated None option in the
1631 args tuple returned by __reduce__().
1632
Brett Cannon84667c02004-12-07 03:25:18 +00001633- optparse now optionally imports gettext. This allows its use in setup.py.
1634
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001635- the pickle module no longer uses the deprecated bin parameter.
1636
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001637- the shelve module no longer uses the deprecated binary parameter.
1638
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001639- the pstats module no longer uses the deprecated ignore() method.
1640
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001641- the filecmp module no longer uses the deprecated use_statcache argument.
1642
Raymond Hettinger664347b2004-12-04 21:21:53 +00001643- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1644 extended or overridden by subclasses. Formerly, the subclassed method would
1645 be ignored by the rest of the module. (Bug #1078905).
1646
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001647- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001648 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001649
Walter Dörwald36733692004-12-22 12:50:50 +00001650- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1651 once when a size argument is given. This prevents a buffer overflow in the
1652 tokenizer with very long source lines.
1653
Barry Warsaw538561e2006-01-01 21:48:54 +00001654- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1655 immediately after creating the object, without any intervening
1656 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001657
Skip Montanaro05885812005-01-16 20:48:27 +00001658- The reconvert.quote function can now emit triple-quoted strings. The
1659 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001660
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001661- ``UserString.MutableString`` now supports negative indices in
1662 ``__setitem__`` and ``__delitem__``
1663
Greg Ward40407942005-03-05 02:53:17 +00001664- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1665 correctly.
1666
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001667- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1668 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1669 character even if the user has passed a size parameter to get a proper
1670 line ending. Remove the special handling of a "\r\n" that has been split
1671 between two lines.
1672
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001673- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1674 about illegal code points. The codec now supports PEP 293 style error
1675 handlers.
1676
Walter Dörwald78a78b02005-09-01 12:04:29 +00001677- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001678 from the input stream, so that the output is a byte string in the correct
1679 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001680
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001681- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1682 considering it exactly like a '*'.
1683
Walter Dörwald007f8df2005-10-09 19:42:27 +00001684- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1685 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001686
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001687- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1688
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001689- Patch #1413711: Certain patterns of differences were making difflib
1690 touch the recursion limit.
1691
Walter Dörwald58917a62006-03-31 15:26:22 +00001692- Bug #947906: An object oriented interface has been added to the calendar
1693 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001694 called as a script (e.g. via ``python -mcalendar``). Localized month and
1695 weekday names can be ouput (even if an exotic encoding is used) using
1696 special classes that use unicode.

Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001710- Patch #881820: look for openpty and forkpty also in libbsd.
1711
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001712- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1713 The zlib module is now builtin on Windows.
1714
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001715- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1716
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001717- Bug #1189330: configure did not correctly determine the necessary
1718 value of LINKCC if python was built with GCC 4.0.
1719
Trent Mick8321b422005-07-26 02:29:21 +00001720- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1721 vulnerability in zlib 1.2.1 and 1.2.2.
1722
Brett Cannon08cd5982005-04-24 22:26:38 +00001723- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1724 flags that change binary compatibility. Changes were also made to
1725 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001726 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001727
Bob Ippolitoed233462005-03-29 13:47:59 +00001728- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1729 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1730 no longer exists). This configure patch makes things right.
1731
Martin v. Löwise2713be2005-03-08 15:03:08 +00001732- Bug #1158607: Build with --disable-unicode again.
1733
Brett Cannon46d96232005-02-16 00:07:19 +00001734- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1735 defined. Discovered as a result of not being able to build on OS X.
1736
Brett Cannon516592f2004-12-07 00:42:59 +00001737- setup.py now uses the directories specified in LDFLAGS using the -L option
1738 and in CPPFLAGS using the -I option for adding library and include
1739 directories, respectively, for compiling extension modules against. This has
1740 led to the core being compiled using the values in CPPFLAGS. It also removes
1741 the need for the special-casing of both DarwinPorts and Fink for darwin since
1742 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1743 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1744 Fink, ``-I/opt/local/include`` for DarwinPorts).
1745
Brett Cannon43802422005-02-10 20:48:03 +00001746- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1747 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1748 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1749 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001751C API
1752-----
1753
Tim Petersc9d78aa2006-03-26 23:27:58 +00001754- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1755 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1756 is obtained via the ``PyObject_`` family, it must be released via the
1757 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1758 always been officially true, but when Python's small-object allocator was
1759 introduced, an attempt was made to cater to a few extension modules
1760 discovered at the time that obtained memory via ``PyObject_New`` but
1761 released it via ``PyMem_DEL``. It's years later, and if such code still
1762 exists it will fail now (probably with segfaults, but calling wrong
1763 low-level memory management functions can yield many symptoms).
1764
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001765- Added a C API for set and frozenset objects.
1766

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001769- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1770 mapping argument now. This string is used as a mapping table. Byte values
1771 greater than the length of the string and 0xFFFE are treated as undefined
1772 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001779
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001780- Patch #1276356: New resource "urlfetch" is implemented. This enables
1781 even impatient people to run tests that require remote files.
