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
Neal Norwitze1fdb322006-07-21 05:32:28 +000015- Fix some potential crashes found with failmalloc.
16
Neal Norwitze7563102006-07-17 01:00:16 +000017- Fix warnings reported by Klocwork's static analysis tool.
18
Neal Norwitz84be93b2006-07-16 01:50:38 +000019- Bug #1512814, Fix incorrect lineno's when code within a function
20 had more than 255 blank lines.
21
Georg Brandl9dceedb2006-07-12 15:31:17 +000022- Patch #1521179: Python now accepts the standard options ``--help`` and
23 ``--version`` as well as ``/?`` on Windows.
24
Neal Norwitza1f10902006-07-12 07:28:29 +000025- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
26 again. Fixing this problem required changing the .pyc magic number.
27 This means that .pyc files generated before 2.5c1 will be regenerated.
28
Tim Peters112aad32006-07-19 00:03:19 +000029- Bug #1524317: Compiling Python ``--without-threads`` failed.
30 The Python core compiles again then, and, in a build without threads, the
31 new ``sys._current_frames()`` returns a dictionary with one entry,
32 mapping the faux "thread id" 0 to the current frame.
33
Neal Norwitza1f10902006-07-12 07:28:29 +000034Library
35-------
36
Greg Ward48fae7a2006-07-23 16:05:51 +000037- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
38
Martin v. Löwis426f4a12006-07-18 17:46:31 +000039- Patch #1524429: Use repr() instead of backticks in Tkinter again.
40
Brett Cannoncaebe222006-07-18 04:41:36 +000041- Bug #1520914: Change time.strftime() to accept a zero for any position in its
42 argument tuple. For arguments where zero is illegal, the value is forced to
43 the minimum value that is correct. This is to support an undocumented but
44 common way people used to fill in inconsequential information in the time
45 tuple pre-2.4.
46
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000047- Patch #1220874: Update the binhex module for Mach-O.
48
Barry Warsawb110bad2006-07-21 14:51:07 +000049- The email package has improved RFC 2231 support, specifically for
50 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
51 (name*0=<blah>) parameter continuations. This may change the types of
52 values returned from email.message.Message.get_param() and friends.
53 Specifically in some cases where non-encoded continuations were used,
54 get_param() used to return a 3-tuple of (None, None, string) whereas now it
55 will just return the string (since non-encoded continuations don't have
56 charset and language parts).
57
58 Also, whereas % values were decoded in all parameter continuations, they are
59 now only decoded in encoded parameter parts.

Neal Norwitza1f10902006-07-12 07:28:29 +000061Extension Modules
62-----------------
63
Martin v. Löwisbda0dde2006-07-24 10:26:33 +000064- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
65
Thomas Hellerce049a02006-07-14 17:51:14 +000066- Patch #1521817: Index range checking on ctypes arrays containing
67 exactly one element enabled again. This allows iterating over these
68 arrays, without the need to check the array size before.
69
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000070- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000071 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000072 /dev/null in certain cases; this is now fixed.
73
Thomas Heller47d7a062006-07-12 08:43:47 +000074- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
75 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000076
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000077- Because of a misspelled preprocessor symbol, ctypes was always
78 compiled without thread support; this is now fixed.

Georg Brandlad29e632006-06-21 17:45:17 +000084
85Core and builtins
86-----------------
87
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000088- Bug #1441486: The literal representation of -(sys.maxint - 1)
89 again evaluates to a int object, not a long.
90
Neil Schemenauer0e07b602006-07-09 16:16:34 +000091- Bug #1501934: The scope of global variables that are locally assigned
92 using augmented assignment is now correctly determined.
93
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000094- Bug #927248: Recursive method-wrapper objects can now safely
95 be released.
96
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000097- Bug #1417699: Reject locale-specific decimal point in float()
98 and atof().
99
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000100- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
101 omit a default "error" argument for NULL pointer. This allows
102 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000103
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000104- Bug #1519018: 'as' is now validated properly in import statements.
105
Neal Norwitz28746ab2006-07-09 22:14:42 +0000106- On 64 bit systems, int literals that use less than 64 bits are
107 now ints rather than longs.
108
Neal Norwitzed657552006-07-10 00:04:44 +0000109- Bug #1512814, Fix incorrect lineno's when code at module scope
110 started after line 256.
111
Tim Peters32a83612006-07-10 21:08:24 +0000112- New function ``sys._current_frames()`` returns a dict mapping thread
113 id to topmost thread stack frame. This is for expert use, and is
114 especially useful for debugging application deadlocks. The functionality
115 was previously available in Fazal Majid's ``threadframe`` extension
116 module, but it wasn't possible to do this in a wholly threadsafe way from
117 an extension.
118
Georg Brandlad29e632006-06-21 17:45:17 +0000119Library
120-------
121
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000122- Patch #1519566: Update turtle demo, make begin_fill idempotent.
123
Tim Peters32a83612006-07-10 21:08:24 +0000124- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000125 environment variable to be set in order to the SDK environment
126 for finding the compiler, include files, etc.
127
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000128- Bug #1515998: Properly generate logical ids for files in bdist_msi.
129
Nick Coghlan2d792252006-07-06 13:47:18 +0000130- warnings.py now ignores ImportWarning by default
131
Thomas Woutersadd19112006-07-05 11:03:49 +0000132- string.Template() now correctly handles tuple-values. Previously,
133 multi-value tuples would raise an exception and single-value tuples would
134 be treated as the value they contain, instead.
135
Martin v. Löwisede77f52006-07-03 13:01:35 +0000136- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
137 even if some data are received.
138
Martin v. Löwis45482392006-07-03 12:28:58 +0000139- Bug #1267547: Put proper recursive setup.py call into the
140 spec file generated by bdist_rpm.
141
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000142- Bug #1514693: Update turtle's heading when switching between
143 degrees and radians.
144
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000145- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000146 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000147
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000148- Bug #1514703: Only setup canvas window in turtle when the canvas
149 is created.
150
Martin v. Löwis7596e832006-07-01 15:33:37 +0000151- Bug #1513223: .close() of a _socketobj now releases the underlying
152 socket again, which then gets closed as it becomes unreferenced.
153
Fred Drake10497c82006-06-29 02:57:48 +0000154- Bug #1504333: Make sgmllib support angle brackets in quoted
155 attribute values.
156
157- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
158 sgmllib ('[' and ']' were not accepted).
159
Georg Brandl1be63af2006-06-28 20:23:25 +0000160- Fix a bug in the turtle module's end_fill function.
161
Brett Cannon53ab5b72006-06-22 16:49:14 +0000162- Bug #1510580: The 'warnings' module improperly required that a Warning
163 category be either a types.ClassType and a subclass of Warning. The proper
164 check is just that it is a subclass with Warning as the documentation states.
165
Georg Brandlad29e632006-06-21 17:45:17 +0000166- The compiler module now correctly compiles the new try-except-finally
167 statement (bug #1509132).
168
Neal Norwitz60373cd2006-06-22 06:30:50 +0000169- The wsgiref package is now installed properly on Unix.
170
Vinay Sajip28e57612006-07-01 10:45:20 +0000171- A bug was fixed in logging.config.fileConfig() which caused a crash on
172 shutdown when fileConfig() was called multiple times.
173
Gerhard Häring762fbd32006-07-02 17:48:30 +0000174- The sqlite3 module did cut off data from the SQLite database at the first
175 null character before sending it to a custom converter. This has been fixed
176 now.
177
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000178Extension Modules
179-----------------
180
Tim Peters112aad32006-07-19 00:03:19 +0000181- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
182 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
183 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000184
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000185- Assigning None to pointer type fields in ctypes structures possible
186 overwrote the wrong fields, this is fixed now.
187
188- Fixed a segfault in _ctypes when ctypes.wintypes were imported
189 on non-Windows platforms.
190
191- Bug #1518190: The ctypes.c_void_p constructor now accepts any
192 integer or long, without range checking.
193
194- Patch #1517790: It is now possible to use custom objects in the ctypes
195 foreign function argtypes sequence as long as they provide a from_param
196 method, no longer is it required that the object is a ctypes type.
197
198- The '_ctypes' extension module now works when Python is configured
199 with the --without-threads option.
200
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000201- Bug #1513646: os.access on Windows now correctly determines write
202 access, again.
203
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000204- Bug #1512695: cPickle.loads could crash if it was interrupted with
205 a KeyboardInterrupt.
206
Neal Norwitza12aa882006-07-06 06:45:08 +0000207- Bug #1296433: parsing XML with a non-default encoding and
208 a CharacterDataHandler could crash the interpreter in pyexpat.
209
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000210- Patch #1516912: improve Modules support for OpenVMS.
211
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000212Build
213-----
214
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000215- Automate Windows build process for the Win64 SSL module.
216
Tim Peters32a83612006-07-10 21:08:24 +0000217- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000218 Previously, the slight difference could cause compilation errors of the
219 'zlib' module on systems with more than one version of zlib.
220
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000221- The MSI compileall step was fixed to also support a TARGETDIR
222 with spaces in it.
223
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000224- Bug #1517388: sqlite3.dll is now installed on Windows independent
225 of Tcl/Tk.
226
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000227- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000228 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000229
Neal Norwitzb15ac312006-06-29 04:10:08 +0000230Tests
231-----
232
233- Call os.waitpid() at the end of tests that spawn child processes in order
234 to minimize resources (zombies).
235
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000236Documentation
237-------------
238
Nick Coghlan2d792252006-07-06 13:47:18 +0000239- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
240 documentation for the warnings module.
241

Anthony Baxter51bcb682006-04-05 14:51:42 +0000250
251Core and builtins
252-----------------
253
Georg Brandla56b9152006-06-19 06:35:54 +0000254- Patch #1507676: Error messages returned by invalid abstract object operations
255 (such as iterating over an integer) have been improved and now include the
256 type of the offending object to help with debugging.
257
Brett Cannonea3912b2006-06-13 21:46:41 +0000258- Bug #992017: A classic class that defined a __coerce__() method that returned
259 its arguments swapped would infinitely recurse and segfault the interpreter.
260
Neal Norwitz909eb122006-06-12 02:13:21 +0000261- Fix the socket tests so they can be run concurrently.
262
Neal Norwitzb9845e72006-06-12 02:11:18 +0000263- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000264 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000265
Brett Cannon22565aa2006-06-09 22:31:23 +0000266- Bug #532646: object.__call__() will continue looking for the __call__
267 attribute on objects until one without one is found. This leads to recursion
268 when you take a class and set its __call__ attribute to an instance of the
269 class. Originally fixed for classic classes, but this fix is for new-style.
270 Removes the infinite_rec_3 crasher.
271
Georg Brandl24250812006-06-09 18:45:48 +0000272- The string and unicode methods startswith() and endswith() now accept
273 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
274
Brett Cannonde3b0522006-06-08 17:00:45 +0000275- Buffer objects, at the C level, never used the char buffer
276 implementation even when the char buffer for the wrapped object was
277 explicitly requested (originally returned the read or write buffer).
278 Now a TypeError is raised if the char buffer is not present but is
279 requested.
280
Georg Brandlddbaa662006-06-04 21:56:52 +0000281- Patch #1346214: Statements like "if 0: suite" are now again optimized
282 away like they were in Python 2.4.
283
Georg Brandlb7c8f542006-05-27 12:30:25 +0000284- Builtin exceptions are now full-blown new-style classes instead of
285 instances pretending to be classes, which speeds up exception handling
286 by about 80% in comparison to 2.5a2.
287
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000288- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
289 Unicode 4.1.
290
Georg Brandlf4ef1162006-05-26 18:03:31 +0000291- Patch #921466: sys.path_importer_cache is now used to cache valid and
292 invalid file paths for the built-in import machinery which leads to
293 fewer open calls on startup.
294
Tim Peters696cf432006-05-24 21:10:40 +0000295- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
296 of-2 bases. The largest speedup is for inputs with about 1000 decimal
297 digits. Conversion from non-power-of-2 bases remains quadratic-time in
298 the number of input digits (it was and remains linear-time for bases
299 2, 4, 8, 16 and 32).
300
Tim Petersb713ec22006-05-23 18:45:30 +0000301- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
302 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
303 an integer close to ``sys.maxint``. This was repaired by patch
304 #1335972, which also gives a nice speedup.
305
Richard Jonescebbefc2006-05-23 18:28:17 +0000306- Patch #1337051: reduced size of frame objects.
307
308- PyErr_NewException now accepts a tuple of base classes as its
309 "base" parameter.
310
Richard Jones7c88dcc2006-05-23 10:37:38 +0000311- Patch #876206: function call speedup by retaining allocated frame
312 objects.
313
Georg Brandl7b90e162006-05-18 07:01:27 +0000314- Bug #1462152: file() now checks more thoroughly for invalid mode
315 strings and removes a possible "U" before passing the mode to the
316 C library function.
317
Neal Norwitz1004a532006-05-15 07:17:23 +0000318- Patch #1488312, Fix memory alignment problem on SPARC in unicode
319
Neal Norwitz373f0a72006-05-15 07:04:36 +0000320- Bug #1487966: Fix SystemError with conditional expression in assignment
321
Martin v. Löwis879768d2006-05-11 13:28:43 +0000322- WindowsError now has two error code attributes: errno, which carries
323 the error values from errno.h, and winerror, which carries the error
324 values from winerror.h. Previous versions put the winerror.h values
325 (from GetLastError()) into the errno attribute.
326
Martin v. Löwis77736712006-05-04 05:51:03 +0000327- Patch #1475845: Raise IndentationError for unexpected indent.
328
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000329- Patch #1479181: split open() and file() from being aliases for each other.
330
Tim Peters44bd9862006-06-01 13:49:23 +0000331- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
332 methods were always silently ignored by dictionaries when comparing keys.
333 They are now passed through (except when using the C API function
334 ``PyDict_GetItem()``, whose semantics did not change).
335
336- Bug #1456209: In some obscure cases it was possible for a class with a
337 custom ``__eq__()`` method to confuse dict internals when class instances
338 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
339 No, you don't have any code that did this ;-)

347
Brett Cannon6ee7d012006-06-08 16:23:04 +0000348- Change binascii.hexlify to accept a read-only buffer instead of only a char
349 buffer and actually follow its documentation.
350
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000351- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
352
Nick Coghlanc649ec52006-05-29 12:43:05 +0000353- Patch #1478788 (modified version): The functional extension module has
354 been renamed to _functools and a functools Python wrapper module added.
355 This provides a home for additional function related utilities that are
356 not specifically about functional programming. See PEP 309.
357
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000358- Patch #1493701: performance enhancements for struct module.
359
Georg Brandl378d5922006-05-17 14:26:50 +0000360- Patch #1490224: time.altzone is now set correctly on Cygwin.
361
Georg Brandl8d3342b2006-05-16 07:38:27 +0000362- Patch #1435422: zlib's compress and decompress objects now have a
363 copy() method.
364
Andrew MacIntyre92913322006-06-13 15:04:24 +0000365- Patch #1454481: thread stack size is now tunable at runtime for thread
366 enabled builds on Windows and systems with Posix threads support.
367
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000368- On Win32, os.listdir now supports arbitrarily-long Unicode path names
369 (up to the system limit of 32K characters).
370
371- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
372 As a result, these functions now raise WindowsError instead of OSError.
373
Tim Peters7a822da2006-05-25 21:50:17 +0000374- ``time.clock()`` on Win64 should use the high-performance Windows
375 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
376 Windows platforms).
377
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000378- Calling Tk_Init twice is refused if the first call failed as that
379 may deadlock.
380
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000381- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
382 accept it without potentially using an uninitialized pointer.
383
384- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
385 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
386 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000387
Gregory P. Smith372b5832006-06-05 18:48:21 +0000388- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000389 [pybsddb project SF patch number 1466734]
390
Gregory P. Smith372b5832006-06-05 18:48:21 +0000391- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
392 parameter is supplied. [SF pybsddb bug #1477863]
393
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000394- bsddb: the __len__ method of a DB object has been fixed to return correct
395 results. It could previously incorrectly return 0 in some cases.
396 Fixes SF bug 1493322 (pybsddb bug 1184012).
397
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000398- bsddb: the bsddb.dbtables Modify method now raises the proper error and
399 aborts the db transaction safely when a modifier callback fails.
400 Fixes SF python patch/bug #1408584.
401
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000402- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000403 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000404 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
405 database calls that would previously deadlock. [SF python bug #775414]
406
Vinay Sajip28e57612006-07-01 10:45:20 +0000407- Patch #1446489: add support for the ZIP64 extensions to zipfile.

427
Georg Brandl83cc0d02006-06-14 08:50:03 +0000428- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
429 mime.types file for determining MIME types.
430
Georg Brandl2605ca82006-06-14 06:08:31 +0000431- Bug #1339007: Shelf objects now don't raise an exception in their
432 __del__ method when initialization failed.
433
Martin v. Löwisd8251432006-06-14 05:21:04 +0000434- Patch #1455898: The MBCS codec now supports the incremental mode for
435 double-byte encodings.
436
Tim Peters43898b42006-06-14 04:09:25 +0000437- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
438 guarantee that adjacent triples in the return list always describe
439 non-adjacent blocks. Previously, a pair of matching blocks could end
440 up being described by multiple adjacent triples that formed a partition
441 of the matching pair.
442
Greg Ward0e0c9f42006-06-11 16:24:11 +0000443- Bug #1498146: fix optparse to handle Unicode strings in option help,
444 description, and epilog.
445
Greg Wardd1c797e2006-06-11 14:42:41 +0000446- Bug #1366250: minor optparse documentation error.
447
Greg Ward7f547402006-06-11 00:40:49 +0000448- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
449 clarify docs.
450
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000451- The wsgiref package has been added to the standard library.
452
Nick Coghlan676725d2006-06-08 13:54:49 +0000453- The functions update_wrapper() and wraps() have been added to the functools
454 module. These make it easier to copy relevant metadata from the original
455 function when writing wrapper functions.
456
Tim Petersd6a9eef2006-06-05 01:48:21 +0000457- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
458 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000459
Martin v. Löwis3f767792006-06-04 19:36:28 +0000460- Patch #1359618: Speed up charmap encoder by using a trie structure
461 for lookup.
462
Tim Petersd609b1a2006-06-02 23:22:51 +0000463- The functions in the ``pprint`` module now sort dictionaries by key
464 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
465 if and only if its display required more than one line, although that
466 wasn't documented. The new behavior increases predictability; e.g.,
467 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
468
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000469- Patch #1497027: try HTTP digest auth before basic auth in urllib2

471
Georg Brandl2b330372006-05-28 20:23:12 +0000472- Patch #1496206: improve urllib2 handling of passwords with respect to
473 default HTTP and HTTPS ports.
474
George Yoshidaf3c65de2006-05-28 16:39:09 +0000475- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
476
Bob Ippolito7298f272006-05-23 18:43:47 +0000477- Patch #1281707: speed up gzip.readline.
478
Georg Brandlb89316f2006-05-17 15:51:16 +0000479- Patch #1180296: Two new functions were added to the locale module:
480 format_string() to get the effect of "format % items" but locale-aware,
481 and currency() to format a monetary number with currency sign.
482
Georg Brandle3a25832006-05-17 14:56:04 +0000483- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
484 and several features added, such as speed and geometry control.
485
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000486- Patch #1488881: add support for external file objects in bz2 compressed
487 tarfiles.
488
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000489- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
490 stdout arguments, making it possible to redirect input and output
491 for remote debugging.
492
493- Patch #1484695: Update the tarfile module to version 0.8. This fixes
494 a couple of issues, notably handling of long file names using the
495 GNU LONGNAME extension.
496
497- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
498 new flag when ``name`` is already the name of an option flag.
499
500- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
501 package.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000539What's New in Python 2.5 alpha 2?
540=================================
541
542*Release date: 27-APR-2006*
543
544Core and builtins
545-----------------
546
Thomas Heller1b046642006-04-18 18:51:06 +0000547- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
548 by converting these apis from macros into exported functions again:
549
550 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
551 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
552 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
553 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
554 PyRun_String Py_CompileString
555
Martin v. Löwis45294a92006-04-18 06:24:08 +0000556- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
557
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000558- All uses of PyStructSequence_InitType have been changed to initialize
559 the type objects only once, even if the interpreter is initialized
560 multiple times.
561
Neal Norwitz61546162006-04-14 05:20:28 +0000562- Bug #1454485, array.array('u') could crash the interpreter. This was
563 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
564 to unicode when it didn't make sense. 'u#' now requires a unicode string.
565
566- Py_UNICODE is unsigned. It was always documented as unsigned, but
567 due to a bug had a signed value in previous versions.
568
Tim Peters3a5e8b12006-04-11 01:44:07 +0000569- Patch #837242: ``id()`` of any Python object always gives a positive
570 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
571 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000572 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000573 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000574
Tim Peters3a5e8b12006-04-11 01:44:07 +0000575 def __hash__(self):
576 return id(self) # WRONG
577
578 because a hash result must be a (short) Python int but it was always
579 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000580 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000581 was always usable as a hash value before this patch. That's no longer
582 necessarily so.
583
584- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000585 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000586 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000587 #1454844)
588
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000589- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
590 involving generators that have paused outside of any ``try`` or ``with``
591 blocks. (In 2.5a1, a paused generator that was part of a reference
592 cycle could not be garbage collected, regardless of whether it was
593 paused in a ``try`` or ``with`` block.)

610 a temporary db (file=None) with the 'n' flag to truncate on open.
611
612- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
613 as older versions cause excessive test failures.

Peter Astrand7d1d4362006-07-14 14:04:45 +0000621- Bug #1223937: subprocess.CalledProcessError reports the exit status
622 of the process using the returncode attribute, instead of
623 abusing errno.
624
Tim Peters711bf302006-04-25 03:31:36 +0000625- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
626 a doctest to be skipped (the code is not run, and the expected output
627 or exception is ignored).
628
Nick Coghlanda2268f2006-04-24 04:37:15 +0000629- Fixed contextlib.nested to cope with exceptions being raised and
630 caught inside exit handlers.
631
Greg Wardab05edc2006-04-23 03:47:58 +0000632- Updated optparse module to Optik 1.5.1 (allow numeric constants in
633 hex, octal, or binary; add ``append_const`` action; keep going if
634 gettext cannot be imported; added ``OptionParser.destroy()`` method;
635 added ``epilog`` for better help generation).
636
Tim Peters21fbd572006-04-21 21:18:10 +0000637- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
638 called from a thread spawned as a side effect of importing a module.
639
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000640- The pydoc module now supports documenting packages contained in
641 .zip or .egg files.
642
643- The pkgutil module now has several new utility functions, such
644 as ``walk_packages()`` to support working with packages that are either
645 in the filesystem or zip files.
646
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000647- The mailbox module can now modify and delete messages from
648 mailboxes, in addition to simply reading them. Thanks to Gregory
649 K. Johnson for writing the code, and to the 2005 Google Summer of
650 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000651
Tim Petersc7605f22006-04-17 21:12:33 +0000652- The ``__del__`` method of class ``local`` in module ``_threading_local``
653 returned before accomplishing any of its intended cleanup.
654

660
Anthony Baxtere29002c2006-04-12 12:07:31 +0000661- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
662 Windows. Bug #1469163.
663
Phillip J. Eby47032112006-04-11 01:07:43 +0000664- The warnings, linecache, inspect, traceback, site, and doctest modules
665 were updated to work correctly with modules imported from zipfiles or
666 via other PEP 302 __loader__ objects.
667
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000668- Patch #1467770: Reduce usage of subprocess._active to processes which
669 the application hasn't waited on.
670
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000671- Patch #1462222: Fix Tix.Grid.
672
Neal Norwitza31bf182006-04-09 03:35:43 +0000673- Fix exception when doing glob.glob('anything*/')
674
Skip Montanaro262fb922006-04-21 02:31:07 +0000675- The pstats.Stats class accepts an optional stream keyword argument to
676 direct output to an alternate file-like object.
677
Anthony Baxter51bcb682006-04-05 14:51:42 +0000678Build
679-----
680
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000681- The Makefile now has a reindent target, which runs reindent.py on
682 the library.
683
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000684- Patch #1470875: Building Python with MS Free Compiler
685
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000686- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000687
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000688- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
689 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000690 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000691 CXX from --with-cxx-main, see description in README.
692
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000693- Patch #1429775: Link extension modules with the shared libpython.
694
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000695- Fixed a libffi build problem on MIPS systems.
696
Tim Peters8931ff12006-05-13 23:28:20 +0000697- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
698 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
699 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000701Tests
702-----
703
Nick Coghlanda2268f2006-04-24 04:37:15 +0000704- test_contextlib now checks contextlib.nested can cope with exceptions
705 being raised and caught inside exit handlers.
706
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000707- test_cmd_line now checks operation of the -m and -c command switches
708
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000709- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
710 it separately and by hand. It also wasn't cleaning up its changes to
711 the current Decimal context.
712
Thomas Woutersabd08882006-04-26 15:53:30 +0000713- regrtest.py now has a -M option to run tests that test the new limits of
714 containers, on 64-bit architectures. Running these tests is only sensible
715 on 64-bit machines with more than two gigabytes of memory. The argument
716 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000724Documentation
725-------------
726
Tim Petersb06d28c2006-05-12 01:57:59 +0000727- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
728
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000729- PEP 343: Added Context Types section to the library reference
730 and attempted to bring other PEP 343 related documentation into
731 line with the implementation and/or python-dev discussions.
732
Tim Peters8dc73d22006-04-24 02:03:16 +0000733- Bug #1337990: clarified that ``doctest`` does not support examples
734 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000737What's New in Python 2.5 alpha 1?
738=================================
739
Anthony Baxterebed3f62006-04-03 15:03:44 +0000740*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000741
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000742Core and builtins
743-----------------
744
Nick Coghlan43832302006-04-23 17:04:07 +0000745- PEP 338: -m command line switch now delegates to runpy.run_module
746 allowing it to support modules in packages and zipfiles
747
Martin v. Löwisc661b882006-04-20 04:54:23 +0000748- On Windows, .DLL is not an accepted file name extension for
749 extension modules anymore; extensions are only found if they
750 end in .PYD.
751
Martin v. Löwisea62d252006-04-03 10:56:49 +0000752- Bug #1421664: sys.stderr.encoding is now set to the same value as
753 sys.stdout.encoding.
754
Neal Norwitz92e212f2006-04-03 04:48:37 +0000755- __import__ accepts keyword arguments.
756
Georg Brandlccadf842006-03-31 18:54:53 +0000757- Patch #1460496: round() now accepts keyword arguments.
758
Anthony Baxter262c00a2006-03-30 10:53:17 +0000759- Fixed bug #1459029 - unicode reprs were double-escaped.
760
Hye-Shik Changd478f342006-03-23 12:32:36 +0000761- Patch #1396919: The system scope threads are reenabled on FreeBSD
762 5.4 and later versions.
763
Neal Norwitze98ccf62006-03-23 05:39:47 +0000764- Bug #1115379: Compiling a Unicode string with an encoding declaration
765 now gives a SyntaxError.
766
Georg Brandlabd1ff82006-03-18 07:59:59 +0000767- Previously, Python code had no easy way to access the contents of a
768 cell object. Now, a ``cell_contents`` attribute has been added
769 (closes patch #1170323).
770
Tim Peterscf79aac2006-03-16 01:14:46 +0000771- Patch #1123430: Python's small-object allocator now returns an arena to
772 the system ``free()`` when all memory within an arena becomes unused
773 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
774 freed. Some applications will see a drop in virtual memory size now,
775 especially long-running applications that, from time to time, temporarily
776 use a large number of small objects. Note that when Python returns an
777 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000778 platform C library will in turn return that memory to the operating system.
779 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000780 appears to be effective at least on Microsoft C and gcc-based systems.
781 Thanks to Evan Jones for hard work and patience.
782
Georg Brandl533ff6f2006-03-08 18:09:27 +0000783- Patch #1434038: property() now uses the getter's docstring if there is
784 no "doc" argument given. This makes it possible to legitimately use
785 property() as a decorator to produce a read-only property.
786
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000787- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
788 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
789 of requiring an int or long in slicing and a few other contexts, enabling
790 other objects (e.g. Numeric Python's integers) to be used as slice indices.
791
Neal Norwitz995acdf2006-03-07 05:01:00 +0000792- Fixed various bugs reported by Coverity's Prevent tool.
793
Brett Cannonbf364092006-03-01 04:25:17 +0000794- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
795 new exception base class, BaseException, which has a new message attribute.
796 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
797 Raising a string exception now raises a DeprecationWarning.
798
Thomas Woutersfb609f42006-02-28 16:37:25 +0000799- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
800 explicitly relative, using 'from .module import name' to mean 'from the same
801 package as this module is in. Imports without dots still default to the
802 old relative-then-absolute, unless 'from __future__ import
803 absolute_import' is used.
804
Brett Cannona7446e32006-02-27 23:39:10 +0000805- Properly check if 'warnings' raises an exception (usually when a filter set
806 to "error" is triggered) when raising a warning for raising string
807 exceptions.
808
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000809- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000810 The name was removed from Include/code.h.
811
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000812- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000813
Guido van Rossum1968ad32006-02-25 22:38:04 +0000814- Patch 1433928:
815 - The copy module now "copies" function objects (as atomic objects).
816 - dict.__getitem__ now looks for a __missing__ hook before raising
817 KeyError.
818
Tim Peters84ef21c2006-02-28 20:39:06 +0000819- PEP 343: with statement implemented. Needs ``from __future__ import
820 with_statement``. Use of 'with' as a variable will generate a warning.
821 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000822 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000823 The following objects have __context__ methods:
824 - The built-in file type.
825 - The thread.LockType type.
826 - The following types defined by the threading module:
827 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
828 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000829
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000830- Fix the encodings package codec search function to only search
831 inside its own package. Fixes problem reported in patch #1433198.
832
833 Note: Codec packages should implement and register their own
834 codec search function. PEP 100 has the details.
835
Tim Peters9ea89d22006-06-04 03:26:02 +0000836- PEP 353: Using ``Py_ssize_t`` as the index type.
837
838- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
839 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
840 now allow Python to make use of memory blocks exceeding 2**32 bytes for
841 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
842 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000843
Neal Norwitzfc76d632006-01-10 06:03:13 +0000844- Patch #1400181, fix unicode string formatting to not use the locale.
845 This is how string objects work. u'%f' could use , instead of .
846 for the decimal point. Now both strings and unicode always use periods.
847
Neal Norwitz671b9e32006-01-09 07:07:12 +0000848- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
849 configure would break checking curses.h.
850
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000851- Bug #959576: The pwd module is now builtin. This allows Python to be
852 built on UNIX platforms without $HOME set.
853
Neal Norwitzc10978f2005-12-19 06:07:16 +0000854- Bug #1072182, fix some potential problems if characters are signed.
855
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000856- Bug #889500, fix line number on SyntaxWarning for global declarations.
857
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000858- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
859
Neal Norwitze7214a12005-12-18 05:03:17 +0000860- Support for converting hex strings to floats no longer works.
861 This was not portable. float('0x3') now raises a ValueError.
862
Barry Warsaw2a38a862005-12-18 01:27:35 +0000863- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000864 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000865 is now displayed in interactive prompt banner.
866
Georg Brandlfa166682005-12-17 21:45:17 +0000867- Implementation of PEP 341 - Unification of try/except and try/finally.
868 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000869 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000870
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000871- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
872 now encodes backslash correctly.
873
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000874- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
875
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000876- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000877 and long longs.
878
Neal Norwitz67715f02005-11-09 06:59:35 +0000879- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000880 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000881 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000882
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000883- Replaced most Unicode charmap codecs with new ones using the
884 new Unicode translate string feature in the builtin charmap
885 codec; the codecs were created from the mapping tables available
886 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
887 encodings now include a mapping for the Apple logo)
888
Tim Peterse3547fd2005-12-16 23:13:57 +0000889- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000890
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000891- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000892
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000893- A new AST parser implementation was completed. The abstract
894 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000895 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000896
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000897- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000898 The following code now raises a SyntaxError: foo(a = i for i in range(10))
899
Neal Norwitz708e51a2005-10-03 04:48:15 +0000900- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
901
Neal Norwitz11bd1192005-10-03 00:54:56 +0000902- SF Bug #887946: fix segfault when redirecting stdin from a directory.
903 Provide a warning when a directory is passed on the command line.
904
Neal Norwitz40d37812005-10-02 01:48:49 +0000905- Fix segfault with invalid coding.
906
907- SF bug #772896: unknown encoding results in MemoryError.
908
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000909- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000910 supported a __len__() method which evaluated to False when the iterator
911 was empty.
912
Guido van Rossum630db602005-09-20 18:49:54 +0000913- On 64-bit platforms, when __len__() returns a value that cannot be
914 represented as a C int, raise OverflowError.
915
Skip Montanarof8948ca2005-09-19 03:54:46 +0000916- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000917 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000918
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000919- SF bug #893549: parsing keyword arguments was broken with a few format
920 codes.
921
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000922- Changes donated by Elemental Security to make it work on AIX 5.3
923 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
924 bug #105470: test_pwd fails on 64bit system (Opteron).
925
Guido van Rossum539c6622005-09-14 17:49:54 +0000926- Changes donated by Elemental Security to make it work on HP-UX 11 on
927 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
928
Georg Brandl4550b8d2005-08-26 06:43:52 +0000929- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000930 (fixes bug #1119418).
931
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000932- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
933
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000934- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
935 exceptions that cause a function to exit.
936
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000937- The implementation of set() and frozenset() was revised to use its
938 own internal data structure. Memory consumption is reduced by 1/3
939 and there are modest speed-ups as well. The API is unchanged.
940
Tim Petersde7990b2005-07-17 23:45:23 +0000941- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
942
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000943- SF bug #1229429: PyObject_CallMethod failed to decrement some
944 reference counts in some error exit cases.
945
Tim Petersecc6e6a2005-07-10 22:30:55 +0000946- SF bug #1185883: Python's small-object memory allocator took over
947 a block managed by the platform C library whenever a realloc specified
948 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000949 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000950 portable way to copy data from the C-managed block into Python's
951 small-object space without risking a memory fault. Python's small-object
952 realloc now leaves such blocks under the control of the platform C
953 realloc.
954
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000955- SF bug #1232517: An overflow error was not detected properly when
956 attempting to convert a large float to an int in os.utime().
957
Raymond Hettinger3296e692005-06-29 23:29:56 +0000958- SF bug #1224347: hex longs now print with lowercase letters just
959 like their int counterparts.
960
Michael W. Hudson188d4362005-06-20 16:52:57 +0000961- SF bug #1163563: the original fix for bug #1010677 ("thread Module
962 Breaks PyGILState_Ensure()") broke badly in the case of multiple
963 interpreter states; back out that fix and do a better job (see
964 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
965 for a longer write-up of the problem).
966
Michael W. Hudsondf888462005-06-03 14:41:55 +0000967- SF patch #1180995: marshal now uses a binary format by default when
968 serializing floats.
969
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000970- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
971 the routines that promise to produce IEEE 754 binary representations
972 of floats now simply copy bytes around.
973
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000974- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
975 278.
976
Brett Cannonc3647ac2005-04-26 03:45:26 +0000977- patch #1109424: int, long, float, complex, and unicode now check for the
978 proper magic slot for type conversions when subclassed. Previously the
979 magic slot was ignored during conversion. Semantics now match the way
980 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000981 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000982 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000983 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000984
Barry Warsawc8d907c2005-04-19 23:43:40 +0000985- Descriptors defined in C with a PyGetSetDef structure, where the setter is
986 NULL, now raise an AttributeError when attempting to set or delete the
987 attribute. Previously a TypeError was raised, but this was inconsistent
988 with the equivalent pure-Python implementation.
989
Michael W. Hudson774479c2005-04-18 08:46:17 +0000990- It is now safe to call PyGILState_Release() before
991 PyEval_InitThreads() (note that if there is reason to believe there
992 are multiple threads around you still must call PyEval_InitThreads()
993 before using the Python API; this fix is for extension modules that
994 have no way of knowing if Python is multi-threaded yet).
995
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000996- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
997 disabled caused a crash.
998
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000999- Bug #1165306: instancemethod_new allowed the creation of a method
1000 with im_class == im_self == NULL, which caused a crash when called.
1001
Tim Petersecc6e6a2005-07-10 22:30:55 +00001002- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001003 fixes the crash seen in bug #1165761
1004
Raymond Hettinger96229b12005-03-11 06:49:40 +00001005- Added two new builtins, any() and all().
1006
Brett Cannon409d8f22005-03-05 06:47:57 +00001007- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001008 (e.g., ``class C(): pass`` is no longer a syntax error).
1009 Patch #1176012 added support to the 'parser' module and 'compiler' package
1010 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001011
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001012- Patch #1115086: Support PY_LONGLONG in structmember.
1013
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001014- Bug #1155938: new style classes did not check that __init__() was
1015 returning None.
1016
Tim Petersecc6e6a2005-07-10 22:30:55 +00001017- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001018 ('\') with a specific error message.
1019
Martin v. Löwisff232d72005-03-03 09:24:38 +00001020- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1021
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001022- Bug #1124295: the __name__ attribute of file objects was
1023 inadvertently made inaccessible in restricted mode.
1024
Tim Petersecc6e6a2005-07-10 22:30:55 +00001025- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001026 an ferror() call.
1027
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001028- min() and max() now support key= arguments with the same meaning as in
1029 list.sort().
1030
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001031- The peephole optimizer now performs simple constant folding in expressions:
1032 (2+3) --> (5).
1033
Raymond Hettingera422c342005-01-11 03:03:27 +00001034- set and frozenset objects can now be marshalled. SF #1098985.
1035
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001036- Bug #1077106: Poor argument checking could cause memory corruption
1037 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001038
Jeremy Hyltonab630502005-02-04 18:44:06 +00001039- The parser did not complain about future statements in illegal
1040 positions. It once again reports a syntax error if a future
1041 statement occurs after anything other than a doc string.
1042
Neil Schemenauercf52c072005-08-12 17:34:58 +00001043- Change the %s format specifier for str objects so that it returns a
1044 unicode instance if the argument is not an instance of basestring and
1045 calling __str__ on the argument returns a unicode instance.
1046
Tim Petersf4e69282006-02-27 17:15:31 +00001047- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1048 current thread state when the auto-GIL-state machinery knows about
1049 it (since the thread state is being deleted, continuing to remember it
1050 can't help, but can hurt if another thread happens to get created with
1051 the same thread id).
1052
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001053Extension Modules

1070
1071- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1072
1073- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001074 is deprecated. The undocumented re.engine variable no longer exists.
1075

1077 SS2 (single-shift 2) escape sequences correctly.
1078
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001079- The unicodedata module was updated to the 4.1 version of the Unicode
1080 database. The 3.2 version is still available as unicodedata.db_3_2_0
1081 for applications that require this specific version (such as IDNA).
1082
Neal Norwitzb62c4332006-03-04 18:35:47 +00001083- The timing module is no longer built by default. It was deprecated
1084 in PEP 4 in Python 2.0 or earlier.
1085
Guido van Rossum1968ad32006-02-25 22:38:04 +00001086- Patch 1433928: Added a new type, defaultdict, to the collections module.
1087 This uses the new __missing__ hook behavior added to dict (see above).
1088
Georg Brandldbd83392006-02-20 09:42:33 +00001089- Bug #854823: socketmodule now builds on Sun platforms even when

1091
Georg Brandlf4f44152006-02-18 22:29:33 +00001092- Patch #1393157: os.startfile() now has an optional argument to specify
1093 a "command verb" to invoke on the file.
1094
Neal Norwitz082b2df2006-02-07 07:04:46 +00001095- Bug #876637, prevent stack corruption when socket descriptor

1097
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001098- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1099 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1100 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1101
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001102- Patch #1422385: The nis module now supports access to domains other
1103 than the system default domain.
1104
Martin v. Löwis14694662006-02-03 12:54:16 +00001105- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1106 are reported, the limit on path name lengths is removed, and stat reports
1107 WindowsError now (instead of OSError).
1108
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001109- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

1199 were set in a different thread than that which called readline.
1200

1202
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001203- operator.itemgetter() and operator.attrgetter() now support retrieving

1229
Raymond Hettingerb2594052004-12-05 09:25:51 +00001230- itertools.islice() now accepts None for the start and step arguments.

Tim Peters112aad32006-07-19 00:03:19 +00001242
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001243- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1244 been renamed to have only a single underscore prefix. This was done to
1245 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001246
Nick Coghlan43832302006-04-23 17:04:07 +00001247- PEP 338: new module runpy defines a run_module function to support
1248 executing modules which provide access to source code or a code object
1249 via the PEP 302 import mechanisms.
1250
Anthony Baxter93f5b932006-04-03 08:05:07 +00001251- The email module's parsedate_tz function now sets the daylight savings
1252 flag to -1 (unknown) since it can't tell from the date whether it should

1259 in attribute values.
1260
Anthony Baxterc51ee692006-04-01 00:57:31 +00001261- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001262 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001263 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001264 module will not be built.
1265
Tim Petersc17976e2006-04-01 00:26:53 +00001266- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1267 aren't officially supported here, and trying to use them will probably
1268 raise an exception some day. But dicts have been allowed, and "mostly
1269 worked", so support for them won't go away without warning.
1270
Georg Brandl338ef7d2006-03-31 18:42:16 +00001271- Bug #1445068: getpass.getpass() can now be given an explicit stream
1272 argument to specify where to write the prompt.
1273
Georg Brandl22ec80b2006-03-31 18:25:44 +00001274- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1281
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001282- Queue.Queue objects now support .task_done() and .join() methods
1283 to make it easier to monitor when daemon threads have completed
1284 processing all enqueued tasks. Patch #1455676.
1285
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001286- popen2.Popen objects now preserve the command in a .cmd attribute.

1289
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001290- email 4.0 package now integrated. This is largely the same as the email 3.0
1291 package that was included in Python 2.3, except that PEP 8 module names are
1292 now used (e.g. mail.message instead of email.Message). The MIME classes
1293 have been moved to a subpackage (e.g. email.mime.text instead of
1294 email.MIMEText). The old names are still supported for now. Several
1295 deprecated Message methods have been removed and lots of bugs have been
1296 fixed. More details can be found in the email package documentation.
1297
Walter Dörwald40108c92006-03-27 08:15:44 +00001298- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1299 (a subclass of tuple) that provides incremental decoders and encoders
1300 (a way to use stateful codecs without the stream API). Python functions
1301 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1302 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1303 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001304
Walter Dörwald067db482006-03-15 22:17:27 +00001305- Patch #1359365: Calling next() on a closed StringIO.String object raises
1306 a ValueError instead of a StopIteration now (like file and cString.String do).
1307 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1308 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001309
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001310- A regrtest option -w was added to re-run failed tests in verbose mode.

1320
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001321- PEP 343: new module contextlib.py defines decorator @contextmanager
1322 and helpful context managers nested() and closing().
1323

Martin v. Löwis3e865952006-01-24 15:51:21 +00001358 specifications, raises IOErrors when proxies for unsupported protocols
1359 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001382 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1383 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1384 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1385 Ronald L. Rivest offered this advice for Python:
1386
1387 "The consensus of researchers in this area (at least as
1388 expressed at the NIST Hash Function Workshop 10/31/05),
1389 is that SHA-256 is a good choice for the time being, but
1390 that research should continue, and other alternatives may
1391 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001392
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001393- Added a subset of Fredrik Lundh's ElementTree package. Available

1462
Georg Brandla4a8b822005-07-15 09:13:21 +00001463- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1464 parameter, but uses the usual "kwargs=None".
1465
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001466- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001467 Patch #1209527 (Contributed by Connelly).
1468
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001469- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1470 to W3C name (404 -> 'Not Found'). RFE #1216944.
1471
Georg Brandl9e43acf2005-07-04 17:16:07 +00001472- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1473 as this can cause problems with apps closing all file descriptors.
1474
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001475- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001476 it can be missing in embedded interpreters

1479
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001480- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1481 error messages.
1482
Georg Brandl379f99d2005-06-26 21:09:38 +00001483- Bug #1108948: Cookie.py produced invalid JavaScript code.
1484
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001485- The tokenize module now detects and reports indentation errors.
1486 Bug #1224621.
1487
Raymond Hettinger68c04532005-06-10 11:05:19 +00001488- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001489 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001490 the generate_tokens() function now accepts a callable argument that
1491 terminates by raising StopIteration.
1492
Georg Brandl9166e1a2005-06-04 09:20:03 +00001493- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1496 component of the path.
1497
Skip Montanaro174dd222005-05-14 20:54:16 +00001498- Patch #1120353: The xmlrpclib module provides better, more transparent,
1499 support for datetime.{datetime,date,time} objects. With use_datetime set
1500 to True, applications shouldn't have to fiddle with the DateTime wrapper
1501 class at all.
1502
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001503- distutils.commands.upload was added to support uploading distribution
1504 files to PyPI.
1505
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001506- distutils.commands.register now encodes the data as UTF-8 before posting
1507 them to PyPI.
1508
Raymond Hettinger267b8682005-03-27 10:47:39 +00001509- decimal operator and comparison methods now return NotImplemented
1510 instead of raising a TypeError when interacting with other types. This
1511 allows other classes to implement __radd__ style methods and have them
1512 work as expected.
1513
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001514- Bug #1163325: Decimal infinities failed to hash. Attempting to
1515 hash a NaN raised an InvalidOperation instead of a TypeError.
1516
Tim Petersecc6e6a2005-07-10 22:30:55 +00001517- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1551
Guido van Rossumd0641422005-02-03 15:01:24 +00001552- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1553 disables recursive traversal through instance attributes, which can
1554 be exploited in various ways.
1555
Tim Peterse3547fd2005-12-16 23:13:57 +00001556- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001557 flags on the HTTP listening socket.
1558
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001559- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1560 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1561
Tim Peterse3547fd2005-12-16 23:13:57 +00001562- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001563 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1564
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001565- Bug #1110478: Revert os.environ.update to do putenv again.
1566
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001567- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1568
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001569- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1570
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001571- Enhancements to the csv module:
1572
1573 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001574 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001575 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001576 + Dialect parameter parsing has been re-implemented to improve error
1577 reporting.
1578 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1579 dictates.
1580 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001581 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001582 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001583 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1584 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001585 + reader now allows \r characters to be quoted (previously it only allowed
1586 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001587 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001588 + Dialect classes passed to the module are no longer instantiated by
1589 the module before being parsed (the former validation scheme required
1590 this, but the mechanism was unreliable).
1591 + The dialect registry now contains instances of the internal
1592 C-coded dialect type, rather than references to python objects.
1593 + the internal c-coded dialect type is now immutable.
1594 + register_dialect now accepts the same keyword dialect specifications
1595 as the reader and writer, allowing the user to register dialects
1596 without first creating a dialect class.
1597 + a configurable limit to the size of parsed fields has been added -
1598 previously, an unmatched quote character could result in the entire
1599 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001600 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001601 the parser field size limit (returning the former limit). The initial
1602 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001603 + A line_num attribute has been added to the reader object, which tracks
1604 the number of lines read from the source iterator. This is not
1605 the same as the number of records returned, as records can span
1606 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001607 + reader and writer objects were not being registered with the cyclic-GC.
1608 This has been fixed.
1609
Brett Cannone6539c42005-01-08 02:43:53 +00001610- _DummyThread objects in the threading module now delete self.__block that is
1611 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1612 lock primitives tend to be limited in number and thus should not be wasted on
1613 a _DummyThread object. Fixes bug #1089632.
1614
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001615- The imghdr module now detects Exif files.
1616
Raymond Hettinger6065d322004-12-20 23:51:53 +00001617- StringIO.truncate() now correctly adjusts the size attribute.
1618 (Bug #951915).
1619
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001620- locale.py now uses an updated locale alias table (built using
1621 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1622 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001623 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001624
Raymond Hettinger3557f422004-12-07 12:02:02 +00001625- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1626
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001627- the pickle module no longer accepts the deprecated None option in the
1628 args tuple returned by __reduce__().
1629
Brett Cannon84667c02004-12-07 03:25:18 +00001630- optparse now optionally imports gettext. This allows its use in setup.py.
1631
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001632- the pickle module no longer uses the deprecated bin parameter.
1633
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001634- the shelve module no longer uses the deprecated binary parameter.
1635
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001636- the pstats module no longer uses the deprecated ignore() method.
1637
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001638- the filecmp module no longer uses the deprecated use_statcache argument.
1639
Raymond Hettinger664347b2004-12-04 21:21:53 +00001640- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1641 extended or overridden by subclasses. Formerly, the subclassed method would
1642 be ignored by the rest of the module. (Bug #1078905).
1643
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001644- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001645 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001646
Walter Dörwald36733692004-12-22 12:50:50 +00001647- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1648 once when a size argument is given. This prevents a buffer overflow in the
1649 tokenizer with very long source lines.
1650
Barry Warsaw538561e2006-01-01 21:48:54 +00001651- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1652 immediately after creating the object, without any intervening
1653 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001654
Skip Montanaro05885812005-01-16 20:48:27 +00001655- The reconvert.quote function can now emit triple-quoted strings. The
1656 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001657
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001658- ``UserString.MutableString`` now supports negative indices in
1659 ``__setitem__`` and ``__delitem__``
1660
Greg Ward40407942005-03-05 02:53:17 +00001661- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1662 correctly.
1663
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001664- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1665 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1666 character even if the user has passed a size parameter to get a proper
1667 line ending. Remove the special handling of a "\r\n" that has been split
1668 between two lines.
1669
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001670- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1671 about illegal code points. The codec now supports PEP 293 style error
1672 handlers.
1673
Walter Dörwald78a78b02005-09-01 12:04:29 +00001674- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001675 from the input stream, so that the output is a byte string in the correct
1676 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001677
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001678- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1679 considering it exactly like a '*'.
1680
Walter Dörwald007f8df2005-10-09 19:42:27 +00001681- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1682 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001683
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001684- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1685
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001686- Patch #1413711: Certain patterns of differences were making difflib
1687 touch the recursion limit.
1688
Walter Dörwald58917a62006-03-31 15:26:22 +00001689- Bug #947906: An object oriented interface has been added to the calendar
1690 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001691 called as a script (e.g. via ``python -mcalendar``). Localized month and
1692 weekday names can be ouput (even if an exotic encoding is used) using
1693 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001694

1706
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001707- Patch #881820: look for openpty and forkpty also in libbsd.
1708
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001709- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1710 The zlib module is now builtin on Windows.
1711
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001712- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1713
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001714- Bug #1189330: configure did not correctly determine the necessary
1715 value of LINKCC if python was built with GCC 4.0.
1716
Trent Mick8321b422005-07-26 02:29:21 +00001717- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1718 vulnerability in zlib 1.2.1 and 1.2.2.
1719
Brett Cannon08cd5982005-04-24 22:26:38 +00001720- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1721 flags that change binary compatibility. Changes were also made to
1722 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001723 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001724
Bob Ippolitoed233462005-03-29 13:47:59 +00001725- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1726 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1727 no longer exists). This configure patch makes things right.
1728
Martin v. Löwise2713be2005-03-08 15:03:08 +00001729- Bug #1158607: Build with --disable-unicode again.
1730
Brett Cannon46d96232005-02-16 00:07:19 +00001731- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1732 defined. Discovered as a result of not being able to build on OS X.
1733
Brett Cannon516592f2004-12-07 00:42:59 +00001734- setup.py now uses the directories specified in LDFLAGS using the -L option
1735 and in CPPFLAGS using the -I option for adding library and include
1736 directories, respectively, for compiling extension modules against. This has
1737 led to the core being compiled using the values in CPPFLAGS. It also removes
1738 the need for the special-casing of both DarwinPorts and Fink for darwin since
1739 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1740 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1741 Fink, ``-I/opt/local/include`` for DarwinPorts).
1742
Brett Cannon43802422005-02-10 20:48:03 +00001743- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1744 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1745 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1746 Closes bug #1096244. Thanks Gregory Bond.

1749-----
1750
Tim Petersc9d78aa2006-03-26 23:27:58 +00001751- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1752 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1753 is obtained via the ``PyObject_`` family, it must be released via the
1754 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1755 always been officially true, but when Python's small-object allocator was
1756 introduced, an attempt was made to cater to a few extension modules
1757 discovered at the time that obtained memory via ``PyObject_New`` but
1758 released it via ``PyMem_DEL``. It's years later, and if such code still
1759 exists it will fail now (probably with segfaults, but calling wrong
1760 low-level memory management functions can yield many symptoms).
1761
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001762- Added a C API for set and frozenset objects.
1763

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001766- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1767 mapping argument now. This string is used as a mapping table. Byte values
1768 greater than the length of the string and 0xFFFE are treated as undefined
1769 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001776
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001777- Patch #1276356: New resource "urlfetch" is implemented. This enables
1778 even impatient people to run tests that require remote files.
